AB - BACKGROUND Increasing attention is being paid to research misconduct in academic journals and in the media, but we know relatively little about its extent or attitudes to research misconduct, or how these are changing. This study therefore aims to investigate PhD candidates' knowledge, own actions and attitudes to specific forms of research misconduct.MATERIAL AND METHOD In autumn 2015, an anonymous questionnaire survey was distributed to all participants in the introductory course for PhD candidates at the Faculty of Medicine at the University of Oslo.RESULTS Altogether 77 PhD candidates (79 %) responded to the questionnaire. A total of 62 % conducted clinical research and 25 % conducted basic research. Around one in four had heard about serious forms of research misconduct in the previous year, and around 4 % were aware of various forms of serious research misconduct in their own department in the previous year. Compared to earlier studies, an increasing number (16 %) responded that they had been subjected to unethical pressure with regard to inclusion or order of authors. Approximately two-thirds were uncertain of whether their department had written policies for academic conduct. One-third of PhD candidates did not disassociate themselves from actions that are generally viewed as scientific misconduct. One-tenth thought it acceptable to falsify or fabricate data in order to expedite publication, one-fifth did not object to taking the credit for others' ideas, and almost half did not believe it was wrong to attempt a number of methods of analysis until one arrived at a significant answer.INTERPRETATION PhD candidates at the Faculty of Medicine were aware of research misconduct, both generally and from their own department. They themselves reported some type of scientific misconduct, and a large majority were uncertain of their department's guidelines. Some of the candidates also accepted several forms of research misconduct. PMID- 27686204 TI - [Attendance in the Norwegian Breast Cancer Screening Programme]. AB - BACKGROUND: A high rate of attendance among women invited to the Norwegian Breast Cancer Screening Programme (NBCSP) is essential to achieve optimal effect, including reduction in breast cancer mortality. This article describes attendance in the programme by county, period and women's age at invitation. MATERIAL AND METHOD: All women in the age group 50 - 69 years who are registered in the National Population Register are invited to attend the NBCSP every second year. In the study period 2007 - 2014, 2 142 369 invitations were sent, and 1 600 293 screening examinations were performed for 710 169 women. Use of the data is pursuant to the Cancer Registry Regulations. RESULTS: Altogether 84 % of the women invited attended at least once in the study period. The average attendance rate per screening round was 75 %. In Rogaland, Nordland and Sogn og Fjordane counties more than 80 % attended, while in Oslo the figure was 62 %. The highest rate of attendance recorded was for women in the age group 62 - 67 years. The attendance in the prior screening round was of influence for reattendance. INTERPRETATION: The mammography screening programme has a high level of acceptance among women in the target group. Possible reasons for the variation in attendance among the county districts should be identified. PMID- 27686205 TI - Congenital thrombotic thrombocytopenic purpura. AB - BACKGROUND: Congenital thrombotic thrombocytopenic purpura (TTP) is a rare, hereditary disorder. Clinically it presents as episodic microangiopathic haemolytic anaemia and thrombocytopenia with varying degrees of damage to internal organs. The condition may present in neonates, but can also present for the first time in adulthood. The prevalence of congenital TTP is particularly high in Norway, and it is therefore important for Norwegian doctors to be aware of the condition. In this article we review the main characteristics of the disease, including its diagnosis and management, and introduce potential new treatments for the future. METHOD: The article is based on a literature search in PubMed as well as the authors' own research and clinical experience. RESULTS: There was great variation in the severity of congenital TTP: from neonatal mortality to disease-free intervals of several years. Episodes are generally precipitated by a trigger. Acute episodes are treated with plasma infusions, and approximately half of all patients experience frequent episodes and require prophylactic infusions to avoid organ damage. The risk of episodes is greatest in neonates, during pregnancy and in association with infections. INTERPRETATION: There is little research-based evidence regarding long-term prognosis in congenital TTP. There is also a need for guidelines to help identify candidates for prophylactic treatment. An international patient registry would provide useful information and form the basis for better guidelines on the monitoring and treatment of these patients.

Neurological manifestations associated with rotavirus infections are well described and range from benign afebrile convulsions to lethal encephalopathy or encephalitis.CASE PRESENTATION We present an uncommon neurological manifestation in a Caucasian child in the course of a rotavirus infection. A 4-year old girl presented with mutism, hypotonia and reduced consciousness. Magnetic resonance imaging revealed diffusion abnormalities in the splenium corpus callosum and bilaterally in the nuclei dentate in the cerebellum. She was diagnosed with rotavirus cerebellitis.INTERPRETATION Her clinical symptoms and the magnetic resonance imaging abnormalities were uncommon and previously described in only a few Caucasian children. The outcome has varied, and some children have shown long term neurological sequela. Treatment with immunoglobulins and corticosteroids has been used in similar cases, but there is no established treatment for this condition.

PMID- 27686215 TI - High expression of MAP7 predicts adverse prognosis in young patients with cytogenetically normal acute myeloid leukemia. AB - Microtubule-associated protein 7 (MAP7) plays an important role in cancer cells. In this study, we identified the prognostic significance of MAP7 expression in cytogenetically normal acute myeloid leukemia (CN-AML) patients (aged <60 years) based on several microarray datasets. In the first group (n = 129), high MAP7 expression (MAP7high) was associated with adverse overall survival (OS; P = 0.0441) and event-free survival (EFS; P = 0.0114) compared with low MAP7 expression (MAP7low). In addition, the prognostic significance of MAP7 was confirmed by European Leukemia Net (ELN) intermediate-I genetic categories and multivariable analysis. In the second independent group of CN-AML patients (aged <60 years), MAP7high was also associated with adverse OS (n = 88, OS; P = 0.00811). To understand the inherent mechanisms of MAP7's prognosis, we investigated genome-wide gene/microRNA expression signatures associated with MAP7 expression. Several known oncogenic genes/microRNAs and anti-oncogenic genes/microRNAs were disordered in MAP7high CN-AML patients. In conclusion, MAP7high is an adverse prognostic biomarker for CN-AML, which may be attributed to the distinctive genome-wide gene/microRNA expression and related cell signaling pathways. PMID- 27686216 TI - Development of dopant-free conductive bioelastomers. AB - Conductive biodegradable materials are of great interest for various biomedical applications, such as tissue repair and bioelectronics. They generally consist of multiple components, including biodegradable polymer/non-degradable conductive polymer/dopant, biodegradable conductive polymer/dopant or biodegradable polymer/non-degradable inorganic additives. The dopants or additives induce material instability that can be complex and possibly toxic. Material softness and elasticity are also highly expected for soft tissue repair and soft electronics. To address these concerns, we designed a unicomponent dopant-free conductive polyurethane elastomer (DCPU) by chemically linking biodegradable segments, conductive segments, and dopant molecules into one polymer chain. The DCPU films which had robust mechanical properties with high elasticity and conductivity can be degraded enzymatically and by hydrolysis. It exhibited great electrical stability in physiological environment with charge. Mouse 3T3 fibroblasts survived and proliferated on these films exhibiting good cytocompatibility. Polymer degradation products were non-toxic. DCPU could also be processed into a porous scaffold and in an in vivo subcutaneous implantation model, exhibited good tissue compatibility with extensive cell infiltration over 2 weeks. Such biodegradable DCPU with good flexibility and elasticity, processability, and electrical stability may find broad applications for tissue repair and soft/stretchable/wearable bioelectronics. PMID- 27686217 TI - Characterization of Amyloid Cores in Prion Domains. AB - Amyloids consist of repetitions of a specific polypeptide chain in a regular cross-beta-sheet conformation. Amyloid propensity is largely determined by the protein sequence, the aggregation process being nucleated by specific and short segments. Prions are special amyloids that become self-perpetuating after aggregation. Prions are responsible for neuropathology in mammals, but they can also be functional, as in yeast prions. The conversion of these last proteins to the prion state is driven by prion forming domains (PFDs), which are generally large, intrinsically disordered, enriched in glutamines/asparagines and depleted in hydrophobic residues. The self-assembly of PFDs has been thought to rely mostly on their particular amino acid composition, rather than on their sequence. Instead, we have recently proposed that specific amyloid-prone sequences within PFDs might be key to their prion behaviour. Here, we demonstrate experimentally the existence of these amyloid stretches inside the PFDs of the canonical Sup35, Swi1, Mot3 and Ure2 prions. These sequences self-assemble efficiently into highly ordered amyloid fibrils, that are functionally competent, being able to promote the PFD amyloid conversion in vitro and in vivo. Computational analyses indicate that these kind of amyloid stretches may act as typical nucleating signals in a number of different prion domains. PMID- 27686218 TI - Comparison of diagnostic validity of mannitol and methacholine challenges and relationship to clinical status and airway inflammation in steroid-naive asthmatic patients. AB - OBJECTIVES: The purpose of this study was to demonstrate and compare the diagnostic validity of two bronchial challenges and to investigate their correlation with patient clinical status, atopy and inflammation markers. METHODS: Eighty-eight patients, 47 women and 41 men, mean age 38.56 +/- 16.73 years who presented with asthma related symptoms and were not on any anti-asthma medication, were challenged with mannitol and methacholine on separate days. Medical history regarding asthmatic symptoms, physical examination, skin prick tests and FeNO levels were also assessed. The clinical diagnosis of asthma was based on bronchodilator reversibility test. RESULTS: Sixty-seven patients were diagnosed with asthma and 21 without asthma. Both methacholine (P < 0.014) and mannitol (P < 0.000) challenges were significant in diagnosing asthma. The positive/negative predictive value was 93.33%/41.86% for methacholine, 97.72%/45.45% for mannitol and 97.05%/45.45%. for both methods assessed together. Worthy of note that 22% of asthmatics had both tests negative. There was a negative correlation between PC20 of methacholine and the FeNO level P < 0.001, and positive with the PD15 of mannitol P < 0.001 and the pre-test FEV1% pred P < 0.005, whereas PD15 of mannitol was negatively correlated with the FeNO level P < 0.001. Furthermore, dyspnea was the only asthmatic symptom associated with FeNO level P < 0.035 and the positivity of mannitol P < 0.014 and methacholine P < 0.04. CONCLUSIONS: Both challenge tests were equivalent in diagnosing asthma. Nevertheless, specificity appeared to be slightly higher in mannitol challenge. PMID- 27686219 TI - Process-based design of dynamical biological systems. AB - The computational design of dynamical systems is an important emerging task in synthetic biology. Given desired properties of the behaviour of a dynamical system, the task of design is to build an in-silico model of a system whose simulated be- haviour meets these properties. We introduce a new, process-based, design methodology for addressing this task. The new methodology combines a flexible process-based formalism for specifying the space of candidate designs with multi-objective optimization approaches for selecting the most appropriate among these candidates. We demonstrate that the methodology is general enough to both formulate and solve tasks of designing deterministic and stochastic systems, successfully reproducing plausible designs reported in previous studies and proposing new designs that meet the design criteria, but have not been previously considered.

PMID- 27686221 TI - A Novel Reference Security Model with the Situation Based Access Policy for Accessing EPHR Data. AB - Electronic Patient Health Record (EPHR) systems may facilitate a patient not only to share his/her health records securely with healthcare professional but also to control his/her health privacy, in a convenient and easy way even in case of emergency. In order to fulfill these requirements, it is greatly desirable to have the access control mechanism which can efficiently handle every circumstance without negotiating security. However, the existing access control mechanisms used in healthcare to regulate and restrict the disclosure of patient data are often bypassed in case of emergencies. In this article, we propose a way to securely share EPHR data under any situation including break-the-glass (BtG) without compromising its security. In this regard, we design a reference security model, which consists of a multi-level data flow hierarchy, and an efficient access control framework based on the conventional Role-Based Access Control (RBAC) and Mandatory Access Control (MAC) policies. PMID- 27686222 TI - Processing Time Reduction: an Application in Living Human High-Resolution Diffusion Magnetic Resonance Imaging Data. AB - High Angular Resolution Diffusion Imaging (HARDI) is a type of brain imaging that collects a very large amount of data, and if many subjects are considered then it amounts to a big data framework (e.g., the human connectome project has 20 Terabytes of data). HARDI is also becoming increasingly relevant for clinical settings (e.g., detecting early cerebral ischemic changes in acute stroke, and in pre-clinical assessment of white matter-WM anatomy using tractography). Thus, this method is becoming a routine assessment in clinical settings. In such settings, the computation time is critical, and finding forms of reducing the processing time in high computation processes such as Diffusion Spectrum Imaging (DSI), a form of HARDI data, is very relevant to increase data-processing speed. Here we analyze a method for reducing the computation time of the dMRI-based axonal orientation distribution function h by using Monte Carlo sampling-based methods for voxel selection. Results evidenced a robust reduction in required data sampling of about 50 % without losing signal's quality. Moreover, we show that the convergence to the correct value in this type of Monte Carlo HARDI/DSI data-processing has a linear improvement in data-processing speed of the ODF determination. Although further improvements are needed, our results represent a promissory step for future processing time reduction in big data. PMID- 27686224 TI - Profiling risk for acute rejection in kidney transplantation: recipient age is a robust risk factor. AB - Careful management of immunosuppression is paramount to prevent acute rejection in kidney transplantation. We studied a cohort of 139,875 kidney transplant recipients from the Organ Procurement and Transplantation Network (OPTN) database between 2002 and 2013. We confirmed the analysis with a cohort of 35,277 who received thymoglobulin induction with tacrolimus maintenance, and a third cohort of 12,161 recipients who received basiliximab induction with tacrolimus maintenance. We performed multivariate logistic regression analyses on data from all three cohorts and identified independent risk factors for treated acute rejection at 1 year. Recipient age was a robust risk factor for rejection in all three cohorts in a dose response pattern. Young age (18-25 years) was among the strongest risk factors for rejection in all three cohorts; thymoglobulin cohort: OR 1.87 (1.59-2.19); basiliximab cohort: OR 2.41 (1.89-3.05); and inclusive cohort: OR 1.97 (1.83-2.12). The opposite was true for old age (65-69 years); thymoglobulin cohort: OR 0.69 (0.59-0.81); basiliximab cohort: OR 0.77 (0.62 0.96); and inclusive cohort: OR 0.75 (0.70-0.80). This study is unique because it is the largest and most comprehensive multivariate analysis that demonstrates recipient age is a robust risk factor for acute rejection in an inverse dose response pattern. PMID- 27686223 TI - Body fluid levels of neuroactive amino acids in autism spectrum disorders: a review of the literature. AB - A review of studies on the body fluid levels of neuroactive amino acids, including glutamate, glutamine, taurine, gamma-aminobutyric acid (GABA), glycine, tryptophan, D-serine, and others, in autism spectrum disorders (ASD) is given. The results reported in the literature are generally inconclusive and contradictory, but there has been considerable variation among the previous studies in terms of factors such as age, gender, number of subjects, intelligence quotient, and psychoactive medication being taken. Future studies should include simultaneous analyses of a large number of amino acids [including D-serine and branched-chain amino acids (BCAAs)] and standardization of the factors mentioned above. It may also be appropriate to use saliva sampling to detect amino acids in ASD patients in the future-this is noninvasive testing that can be done easily more frequently than other sampling, thus providing more dynamic monitoring. PMID- 27686226 TI - Comparison of mirabegron and imidafenacin for efficacy and safety in Japanese female patients with overactive bladder: A randomized controlled trial (COMFORT study). AB - OBJECTIVES: To evaluate the efficacy and safety of mirabegron compared with imidafenacin for the treatment of female patients with overactive bladder. METHODS: Patients (n = 89) were randomized to receive 0.1 mg imidafenacin twice daily (n = 47) or 50 mg mirabegron once daily (n = 42) for 12 weeks. The primary efficacy end-point was change in total Overactive Bladder Symptom Score. Secondary efficacy end-points included change in Overactive Bladder Symptom Score, 3-day micturition diary, International Prostate Symptom Score and Overactive Bladder Questionnaire. Safety assessments included adverse events, vital signs, post-void residual volume and patient-reported incidence, and severity of distinctive symptoms related to adverse events. RESULTS: The mirabegron group showed a significantly reduced mean total Overactive Bladder Symptom Score from baseline, but no significant differences were noted in change of total Overactive Bladder Symptom Score compared with the imidafenacin group. Significant improvements in secondary efficacy end-points were observed regarding the mean number of micturitions/24 h, mean number of urgency episodes/24 h, mean number of incontinence episodes/24 h, mean volume voided/micturition, total International Prostate Symptom Score and quality of life in both groups, with no significant differences between the groups. The overall incidence of adverse events and the incidence of dry mouth were significantly higher in the imidafenacin group than in the mirabegron group. Patient-reported incidence and the severity of dry mouth were significantly exacerbated in the imidafenacin group. CONCLUSIONS: Treatment with 50 mg mirabegron once daily effectively relieves overactive bladder symptoms in women with fewer adverse events than treatment with antimuscarinics. PMID- 27686225 TI - Association of Calf Muscle Pump Stimulation With Sleep Quality in Adults. AB - Prevention of lower extremity fluid pooling (LEFP) is associated with improved sleep quality. Physical activity and compression stockings are non-invasive methods used to manage LEFP, but both are associated with low adherence. Calf muscle pump (CMP) stimulation is an alternative and more convenient approach. Convenience sampling was used to recruit 11 participants between ages 45 and 65 with poor sleep quality. A within-person single-group pre-test-post-test design was used to evaluate changes in sleep quality, daytime sleepiness, and functional outcomes sensitive to impaired sleep as measured by the Pittsburgh Sleep Quality Index (PSQI), Functional Outcomes of Sleep Questionnaire, and Epworth Sleepiness Scale after 4 weeks of CMP stimulation. Statistical analysis included effect size (ES) calculations. After daily use of CMP stimulation, participants demonstrated improvement in overall sleep quality (ES = -.97) and a large reduction in daily disturbance from poor sleep (ES = -1.25). Moderate improvements were observed in daytime sleepiness (ES = -.53) and functional outcomes sensitive to sleepiness (ES = .49). Although causality could not be determined with this study design, these results support further research to determine whether CMP stimulation can improve sleep quality.

PMID- 27686227 TI - Synergistic Coordination and Hydrogen Bonding Interaction Modulate the Emission of Iridium Complex for Highly Sensitive Glutamine Imaging in Live Cells. AB - Highly selective detection of intracellular glutamine (Gln) is very essential to understand the roles of Gln in some biological processes. Here, we report a new fluorescent method for selective imaging of Gln in live cells with an aldehyde containing iridium complex, [Ir(pba)2(DMSO)2]PF6 (Hpba = 4-(2 pyridiyl)benzaldehyde) (Ir1), as the probe. Density functional theory (DFT) calculation and experimental results suggest that the coordination and hydrogen bonding interaction between Ir1 and Gln synergistically stabilize the Ir1-Gln complex, modulate charge-transfer characteristics and emission of Ir1, and as a consequence, enable Ir1 as the probe for the fluorescent sensing of Gln. The sensing strategy is well-responsive to Gln without interference from other amino acids or Gln-containing peptides and is demonstrated to be useful for in situ Gln imaging in live cells. The study provides a new method for fluorescent imaging of Gln in live cells, which is envisioned to find interesting applications in understanding the roles of Gln in some physiological processes. PMID- 27686228 TI - The UCA1/miR-204/Sirt1 axis modulates docetaxel sensitivity of prostate cancer cells. AB - PURPOSE: In this study, we firstly investigated the regulative effect of miR-204 on Sirt1 expression in prostate cancer cells. Then, we examined whether miR-204 downregulation in the cells is a result of UCA1 upregulation. In addition, the regulative effect of UCA1/miR-204/Sirt1 axis on docetaxel sensitivity of prostate cancer cells was studied. METHODS: QRT-PCR was performed to detect UCA1, miR-204 and Sirt1 mRNA expression. Western blot assay was performed to assess Sirt1, P-gp and caspase-3 expression. The regulative effect of UCA1/miR-204/Sirt1 axis on docetaxel sensitivity of prostate cancer cells was examined by measurement of docetaxel IC50, dictation of cleaved caspase-3 and flow cytometric analysis of cell apoptosis. RESULTS: MiR-204 negatively modulated Sirt1 expression in prostate cancer cells. UCA1 upregulation directly resulted in decreased miR-204 expression. UCA1 overexpression resulted in increased Sirt1 expression in PNT2 cells, while knockdown of endogenous UCA1 led to decreased Sirt1 in LNCaP and 22RV1 cells. UCA1 siRNA, Sirt1 siRNA and miR-204 mimics could enhance docetaxel induced activation of caspase-3 and cell apoptosis in 22RV1/DR cells. CONCLUSIONS: There is a UCA1/miR-204/Sirt1 axis in LNCaP and 22RV1 cells. The UCA1/miR-204/Sirt1 axis plays an important role in modulating in vitro docetaxel sensitivity of the prostate cancer cells. PMID- 27686229 TI - [Not Available]. PMID- 27686230 TI - Correlation of blood biomarkers with age informs pathomechanisms in succinic semialdehyde dehydrogenase deficiency (SSADHD), a disorder of GABA metabolism. AB - We hypothesized that blood levels of gamma-aminobutyric acid (GABA) and gamma hydroxybutyric acid (GHB), biomarkers of succinic semialdehyde dehydrogenase deficiency (SSADHD), would correlate with age. GABA and GHB were quantified in plasma and red blood cells (RBCs) from 18 patients (age range 5-41 years; median 8). Both metabolites negatively correlated with age (P < 0.05). Plasma and RBC GHB declined with age, reaching a nadir and approximate steady state by 10 years. Declining plasma GABA achieved this approximate steady state at 30-40 years of age. These biomarker relationships may reflect further GABA- and GHB-ergic neurotransmission imbalances that correlate with the onset of adolescent/adulthood neuropsychiatric morbidity and epilepsy in SSADHD.

PMID- 27686232 TI - Predictive Value of C-Reactive Protein for Complications Post-Laparoscopic Roux En-Y Gastric Bypass. AB - BACKGROUND: Laparoscopic roux-en-Y gastric bypass (LRYGB) has gained increasing popularity as the primary procedure of choice for the management of patients with morbid obesity. Despite the advances, a few patients will still develop complications and predicting these early complications in morbidly obese patients can prove to be difficult. Radiological investigations have limited diagnostic value and have associated side effects and cost. We propose that C-reactive protein (CRP) is a useful predictor for early postoperative complications. This study aims to determine the ability of CRP taken on postoperative day 1 (POD 1) and 2 to predict occurrence of complications within 30 days of surgery. METHODS: This retrospective observational study selected 183 consecutive patients from the York bariatric database between 01 December 2010 and 23 March 2015. EXCLUSIONS: Patients undergoing dual procedures, conversion to open, and if no postoperative CRP measurement was performed. RESULTS: In total, 138 patients satisfied the inclusion criteria during the study period (median age 44 years [20-68], BMI 50.6 kg/m2 [38.3-62.5]). Fifteen (10.8 %) patients had minor complications (CD of 2) and 8 (5.6 %) had major complications (CD 3 or above). A CRP of greater than 127 mg/L on POD 2 was found to predict complications with 93 % sensitivity and 64 % specificity with diagnostic accuracy 0.82 (95 % confidence interval 0.731-0.908). CONCLUSIONS: In our patients, CRP on POD 2 has been shown to be a good predictor of both minor and major complications and can therefore be used to guide clinicians in making decision as to which patients may need further investigation or who can be safely discharged. PMID- 27686233 TI - The Impact of Biliopancreatic Diversion with Duodenal Switch (BPD/DS) Over 9 Years. AB - BACKGROUND: There is limited information on the multiple long-term effects of the biliopancreatic diversion with duodenal switch (BPD/DS). METHODS: Patients who consented to a BPD/DS from 1999 to 2010 were evaluated for weight change, complications, comorbidity resolution, body composition, quality of life, and depressive symptoms during visits at 1, 3,5, 7, and 9 years. Descriptive statistics, analysis of variance, and pair-wise comparisons were calculated for each of the five follow-up cohorts vs. the baseline cohort. RESULTS: Between 1999 and 2010, 284 patients received a BPD/DS; 275 patients (69.8 % women) age 42.7 years, BMI 53.4 kg/m2 qualified for baseline analysis. Two hundred seventy-five patients were available in year 1; 275 patients in year 3; 273 patients in year 5; 259 patients in year 7; and 228 patients in year 9. Gender distribution was not different. BMI was 30.1 at 1 year and 32.0 at 9 years. Body fat was reduced to 26 % after 2 years. Complications requiring surgery were significant. Nutritional problems developed in 29.8 % of patients over the course of observation. The baseline Beck Depression Index (BDI) was 13.9 and 7.2 in year 1. Year 1 through 9 remained unchanged. There were significant positive changes in quality of life between baseline and year 1 for most domains. These positive changes were maintained for the follow-up cohorts. After surgery the resolution of comorbidities continued for the 9 years. CONCLUSIONS: Weight loss during the first year was well maintained, resolving comorbidities and improving quality of life. Rates of surgical complications resemble other bariatric procedures. Long term nutrient deficiencies are of concern. PMID- 27686234 TI - Prospective Comparison and Quality of Life for Single-Incision and Conventional Laparoscopic Sleeve Gastrectomy in a Series of Morbidly Obese Patients. AB - BACKGROUND: Laparoscopic sleeve gastrectomy has gained a wide acceptance in the surgical community with an increasing popularity in the field of bariatric surgery. Simultaneously more surgeons have become acquainted with the single port techniques and sleeve gastrectomy has been regarded as an ideal field of application. Literature is scarce about operative and clinical outcomes of single port sleeve gastrectomy compared to conventional laparoscopy. The primary purpose of the study was to compare operative outcomes in the two study groups. Assessment and comparison of functional outcomes in terms of quality of life between groups was also performed. METHODS: Prospective data on 130 consecutive patients who underwent randomized SI or CL sleeve gastrectomy were collected between January 2009 to December 2014. Preoperative parameters, outcomes, post operative functional results and quality of life, according to the short-form SF 36 questionnaire, were evaluated and compared between groups. RESULTS: 65 patients underwent conventional laparoscopic (CL) and 65 single incision (SI) sleeve gastrectomy. Operative time, post-operative pain, in-hospital stay, and complications were similar in the two groups. No difference emerged with respect to passage of flatus and resumption of oral intake (p = NS). Cosmetic results were excellent in SI patients with higher satisfaction rates. Post-operative quality of life was significant higher compared to baseline (p < 0.05), and comparable between the two procedures. CONCLUSIONS: Single incision sleeve gastrectomy is safe, effective and comparable to the conventional laparoscopic technique in terms of outcomes. Post-operative quality of life is comparable between the two procedures. PMID- 27686235 TI - Prognostic factors for severe Pneumocystis jiroveci pneumonia of non-HIV patients in intensive care unit: a bicentric retrospective study. AB - BACKGROUND: Pneumocystis jiroveci pneumonia (PJP) in non-HIV patients is still a challenge for intensivists. The aim of our study was to evaluate mortality predictors of PJP patients requiring Intensive care unit (ICU) admission. METHODS: Retrospectively review medical records of patients with diagnosis of PJP admitted to four ICUs of two academic medical centers from October 2012 to October 2015. RESULTS: Eighty-two patients were enrolled in the study. Overall hospital mortality was 75.6 %. Compared with survivors, the non-survivors had older age (55 +/- 16 vs. 45 +/- 17, p = 0.014), higher APACHE II score (20 +/- 5 vs. 17 +/- 5, p = 0.01), lower white blood cell count (7.68 +/- 3.44 vs. 10.48 +/ 4.62, p = 0.005), less fever (80.6%vs. 100 %, p = 0.033), more hypotension (58.1 % vs. 20 %, p = 0.003), more pneumomediastinum (29 % vs. 5 %, p = 0.027). Logistic regression analysis demonstrated that age [odds ratio (OR)1.051; 95 % CI 1.007-1.097; p = 0.022], white blood cell count [OR 0.802; 95 % CI 0.670-0.960; p = 0.016], and pneumomediastinum [OR 16.514; 95 % CI 1.330-205.027; p = 0.029] were independently associated with hospital mortality. CONCLUSIONS: Mortality rate for non-HIV PJP patients requiring ICU admission was still high. Poor prognostic factors included age, white blood cell count and pneumomediastinum.

AB - The objective of this study was to investigate the toxic effects of arsenic on testicular measurements and histology of adult Teddy goats bucks and to examine whether these toxic effects are scavenged by vitamin E. Twelve adult Teddy goat bucks were divided randomly into three groups, A, B and C. Group A was kept as control, the B was given sodium arsenite 5 mg/kg BW per day, and group C was fed with vitamin E 200 mg/kg BW per day + arsenic 5 mg/kg BW per day. This treatment was continued for 84 days. Analysis of data revealed that the testicular measurements (scrotal circumference, width, length and weight) were significantly reduced in arsenic-treated animals, whereas there were ameliorating effects of vitamin E on these parameters. The major histopathological changes were present in the form of loss of germinal epithelium, atrophy of Leydig cells and vacuolations. Vitamin E in combination with sodium arsenite increased the active spermatogenesis as well as restoration of germinal epithelium. It can be concluded from the present findings that sodium arsenite causes toxicity in the male reproductive system of Teddy goat bucks with major changes in parenchyma of testes. Supplementation of vitamin E has protective effects on the toxicity of sodium arsenite on the reproductive system of male Teddy goat bucks. PMID- 27686237 TI - Emotional Intelligence and Personality Traits as Predictors of Occupational Therapy students' Practice Education Performance: A Cross-Sectional Study. AB - This study investigated whether occupational therapy students' emotional intelligence and personality traits are predictive of specific aspects of their fieldwork performance. A total of 114 second and third year undergraduate occupational therapy students (86.6% response rate) completed the Genos Emotional Intelligence Inventory (Genos EI) and the Ten-Item Personality Inventory (TIPI). Fieldwork performance scores were obtained from the Student Practice Evaluation Form Revised (SPEF-R). Linear regressions were completed with the SPEF-R domains being the dependent variables and the Genos EI and TIPI factors being the independent variables. Regression analysis results revealed that the Genos EI subscales of Emotional Management of Others (EMO), Emotional Awareness of Others (EAO), Emotional Expression (EEX) and Emotional Reasoning (ERE) were significant predictors of various domains of students' fieldwork performance. EAO and ERE were significant predictors of students' Communication Skills accounting for 4.6% of its variance. EMO, EAO, EEX and ERE were significant predictors of students' Documentation Skills explaining 6.8% of its variance. EMO was a significant predictor of students' Professional Behaviour accounting for 3.2% of its variance. No TIPI factors were found to be significant predictors of the SPEF-R domains. Occupational therapy students' emotional intelligence was a significant predictor of components of their fieldwork performance while students' personality traits were not. The convenience sampling approach used, small sample size recruited and potential issue of social desirability of the self-reported Genos EI and TIPI data are acknowledged as study limitations. It is recommended that other studies be completed to investigate if any other relevant constructs or factors are predictive of occupational therapy students' fieldwork performance.

AB - BACKGROUND: In the recent International Study Group of Pancreatic Surgery (ISGPS) consensus on extended pancreatectomy, several issues on perioperative outcome and long-term survival remained unclear. Robust data on outcomes are sparse. The present study aimed to assess the outcome of extended pancreatectomy for borderline resectable and locally advanced pancreatic cancer. METHODS: A consecutive series of patients with primary pancreatic adenocarcinoma undergoing extended pancreatectomies, as defined by the new ISGPS consensus, were compared with patients who had a standard pancreatectomy. Univariable and multivariable analysis was performed to identify risk factors for perioperative mortality and characteristics associated with survival. Long-term outcome was assessed by means of Kaplan-Meier analysis. RESULTS: The 611 patients who had an extended pancreatectomy had significantly greater surgical morbidity than the 1217 patients who underwent a standard resection (42.7 versus 34.2 per cent respectively), and higher 30-day mortality (4.3 versus 1.8 per cent) and in hospital mortality (7.5 versus 3.6 per cent) rates. Operating time of 300 min or more, extended total pancreatectomy, and ASA fitness grade of III or IV were associated with increased in-hospital mortality in multivariable analysis, whereas resections involving the colon, portal vein or arteries were not. Median survival and 5-year overall survival rate were reduced in patients having extended pancreatectomy compared with those undergoing a standard resection (16.1 versus 23.6 months, and 11.3 versus 20.6 per cent, respectively). Older age, G3/4 tumours, two or more positive lymph nodes, macroscopic positive resection margins, duration of surgery of 420 min or above, and blood loss of 1000 ml or more were independently associated with decreased overall survival. CONCLUSION: Extended resections are associated with increased perioperative morbidity and mortality, particularly when extended total pancreatectomy is performed. Favourable long-term outcome is achieved in some patients. PMID- 27686239 TI - Interpretation of Workplace Tests for Cannabinoids. AB - Workplace urine drug testing for an inactive THC metabolite is common in both federally regulated and non-regulated drug testing. A positive result does not document impairment, or even recent use, when impairment is likely the most important parameter being searched for by the drug testing procedure. Most cannabinoid testing does not detect imported synthetics. Currently, urine is the most widely tested matrix, but blood, plasma, oral fluid, and hair may also be accepted in federally regulated testing in the future. This article will discuss the history, the status quo, and the possible near term future of workplace testing for marijuana in employees. PMID- 27686240 TI - Sulfate metabolites as alternative markers for the detection of 4 chlorometandienone misuse in doping control. AB - Sulfate metabolites have been described as long-term metabolites for some anabolic androgenic steroids (AAS). 4-chlorometandienone (4Cl-MTD) is one of the most frequently detected AAS in sports drug testing and it is commonly detected by monitoring metabolites excreted free or conjugated with glucuronic acid. Sulfation reactions of 4Cl-MTD have not been studied. The aim of this work was to evaluate the sulfate fraction of 4Cl-MTD metabolism by liquid chromatography tandem mass spectrometry (LC-MS/MS) to establish potential long-term metabolites valuable for doping control purposes. 4Cl-MTD was administered to two healthy male volunteers and urine samples were collected up to 8 days after administration. A theoretical selected reaction monitoring (SRM) method working in negative mode was developed. Ion transitions were based on ionization and fragmentation behaviour of sulfate metabolites as well as specific neutral losses (NL of 15 Da and NL of 36 Da) of compounds with related chemical structure. Six sulfate metabolites were detected after the analysis of excretion study samples. Three of the identified metabolites were characterized by liquid chromatography tandem mass spectrometry (LC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS). Results showed that five out of the six identified sulfate metabolites were detected in urine up to the last collected samples from both excretion studies. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27686241 TI - A synthetic three-dimensional niche system facilitates generation of functional hematopoietic cells from human-induced pluripotent stem cells. AB - BACKGROUND: The efficient generation of hematopoietic stem cells (HSCs) from human-induced pluripotent stem cells (iPSCs) holds great promise in personalized transplantation therapies. However, the derivation of functional and transplantable HSCs from iPSCs has had very limited success thus far. METHODS: We developed a synthetic 3D hematopoietic niche system comprising nanofibers seeded with bone marrow (BM)-derived stromal cells and growth factors to induce functional hematopoietic cells from human iPSCs in vitro. RESULTS: Approximately 70 % of human CD34+ hematopoietic cells accompanied with CD43+ progenitor cells could be derived from this 3D induction system. Colony-forming-unit (CFU) assay showed that iPSC-derived CD34+ cells formed all types of hematopoietic colonies including CFU-GEMM. TAL-1 and MIXL1, critical transcription factors associated with hematopoietic development, were expressed during the differentiation process. Furthermore, iPSC-derived hematopoietic cells gave rise to both lymphoid and myeloid lineages in the recipient NOD/SCID mice after transplantation. CONCLUSIONS: Our study underscores the importance of a synthetic 3D niche system for the derivation of transplantable hematopoietic cells from human iPSCs in vitro thereby establishing a foundation towards utilization of human iPSC-derived HSCs for transplantation therapies in the clinic. PMID- 27686242 TI - The Lund University Checklist for Incipient Exhaustion: a prospective validation of the onset of sustained stress and exhaustion warnings. AB - BACKGROUND: The need for instruments that can assist in detecting the prodromal stages of stress-related exhaustion has been acknowledged. The aim of the present study was to evaluate whether the Lund University Checklist for Incipient Exhaustion (LUCIE) could accurately and prospectively detect the onset of incipient exhaustion and to what extent work stressor exposure and private burdens were associated with increasing LUCIE scores. METHODS: Using surveys, 1355 employees were followed for 11 quarters. Participants with prospectively elevated LUCIE scores were targeted by three algorithms entailing 4 quarters: (1) abrupt onset to a sustained Stress Warning (n = 18), (2) gradual onset to a sustained Stress Warning (n = 42), and (3) sustained Exhaustion Warning (n = 36). The targeted participants' survey reports on changes in work situation and private life during the fulfillment of any algorithm criteria were analyzed, together with the interview data. Participants untargeted by the algorithms constituted a control group (n = 745). RESULTS: Eighty-seven percent of participants fulfilling any LUCIE algorithm criteria (LUCIE indication cases) rated a negative change in their work situation during the 4 quarters, compared to 48 % of controls. Ratings of negative changes in private life were also more common in the LUCIE indication groups than among controls (58 % vs. 29 %), but free-text commentaries revealed that almost half of the ratings in the LUCIE indication groups were due to work-to-family conflicts and health problems caused by excessive workload, assigned more properly to work-related negative changes. When excluding the themes related to work-stress-related private life compromises, negative private life changes in the LUCIE indication groups dropped from 58 to 32 %, while only a negligible drop from 29 to 26 % was observed among controls. In retrospective interviews, 79 % of the LUCIE indication participants confirmed exclusively/predominantly work stressors, while 6 % described a predominance of private life stressors. CONCLUSIONS: Negative changes in the work situation were the most prominent change related to a sustained increase in LUCIE scores. The findings seem to confirm that LUCIE is a potentially useful tool for clinical screening of incipient work-related exhaustion. PMID- 27686243 TI - Analysis of the predictive qualities of betting odds and FIFA World Ranking: evidence from the 2006, 2010 and 2014 Football World Cups. AB - The present study aims to investigate the ability of a new framework enabling to derive more detailed model-based predictions from ranking systems. These were compared to predictions from the bet market including data from the World Cups 2006, 2010, and 2014. The results revealed that the FIFA World Ranking has essentially improved its predictive qualities compared to the bet market since the mode of calculation was changed in 2006. While both predictors were useful to obtain accurate predictions in general, the world ranking was able to outperform the bet market significantly for the World Cup 2014 and when the data from the World Cups 2010 and 2014 were pooled. Our new framework can be extended in future research to more detailed prediction tasks (i.e., predicting the final scores of a match or the tournament progress of a team). PMID- 27686244 TI - Physician trust and depression influence adherence to factor replacement: a single-centre cross-sectional study. AB - INTRODUCTION: Poor adherence to factor replacement therapy among patients with haemophilia can lead to joint bleeding and eventual disability. AIM: The aim of this study was to determine patient-related characteristics associated with adherence to factor replacement in adults with haemophilia. METHODS: Adults with haemophilia were recruited to participate in this cross-sectional study. Adherence was measured using either the Validated Hemophilia Regimen Treatment Adherence Scale (VERITAS)-Pro or the VERITAS-PRN questionnaire. Simple and multiple regression analyses that controlled for confounding were performed to determine the association between patient-related characteristics and adherence to factor replacement therapy. RESULTS: Of the 99 subjects enrolled, all were men; 91% had haemophilia A and 78% had severe disease. Age ranged from 18 to 62 years. Most (95%) had functional health literacy; but only 23% were numerate. Mean adherence scores were 45.6 (SD 18) and 51.0 (SD 15) for those on a prophylactic and those on an episodic regimen, respectively, with a lower score indicating better adherence. On multivariable analysis, being on any chronic medication, longer duration followed at our haemophilia treatment centre, higher physician trust and better quality of life were associated with higher adherence. A history of depression was associated with lower adherence. CONCLUSION: Two potentially modifiable characteristics, physician trust and depression, were identified as motivator and barrier to adherence to factor replacement therapy. Promoting a high level of trust between the patient and the healthcare team as well as identifying and treating depression may impact adherence to factor replacement therapy and accordingly reduce joint destruction. PMID- 27686245 TI - Usage of personal music players in adolescents and its association with noise induced hearing loss: A cross-sectional analysis of Ohrkan cohort study data. AB - OBJECTIVE: To describe personal music player (PMP) usage among adolescents, sociodemographic determinants and association with audiometric notches. DESIGN: Audiometric evaluation to assess hearing status, and standardized questionnaires to evaluate PMP listening behaviors, leisure noise exposures and self-reported hearing loss symptoms. Sociodemographic information was collected using a parent questionnaire. Noise exposure by PMP usage equivalent for a 40 h week was estimated based on self-reported volume and duration of use. STUDY SAMPLE: A total of 2143 students (54% females) attending 9th grade in Regensburg, Germany, during 2009 to 2011. RESULTS: Overall, 85% of the students reported using PMPs. Exposure level exceeded 80 dB(A) in approximately one third, and 85 dB(A) in one quarter, of those who used PMP. An audiometric notch was found in 2.3% of participants, but was not significantly associated with higher PMP exposure. CONCLUSIONS: PMP exposure above the occupational limits of 80 and 85 dB(A) set by the Directive 2003/10/EC may be a risk factor for developing noise-induced hearing loss. Educational measures to ameliorate high risk behaviors in PMP usage are needed, particularly for socially disadvantaged groups. PMID- 27686246 TI - A review of the sentinel prey method as a way of quantifying invertebrate predation under field conditions. AB - Sentinel prey can provide a direct, quantitative measure of predation under field conditions. Live sentinel prey provides more realistic data but rarely allows the partitioning of the total predation pressure; artificial prey is less natural but traces left by different predators are identifiable, making it suitable for comparative studies. We reviewed the available evidence of the use of both types of invertebrate sentinel prey. Fifty-seven papers used real prey, usually measuring predation on a focal (often pest) species, with studies overwhelmingly from North America. The median predation was 25.8% d-1 . Artificial sentinel prey (45 papers) were used in both temperate and tropical areas, placed more above ground than at ground level. The most commonly used artificial prey imitated a caterpillar. Up to 14 predator groups were identified, registering a median of 8.8% d-1 predation; half the studies reported only bird predation. Predation on real prey was higher than on artificial ones, but invertebrate predation was not higher than vertebrate predation. Invertertebrate but not vertebrate predation was negatively related to prey size. Predation near the Equator was not higher than at higher latitudes, nor in cultivated than noncultivated habitats. The use of sentinel prey is not yet standardised in terms of prey size, arrangement, exposure period or data reporting. Due to the simplicity and ease of use of the method, such standardisation may increase the usefulness of comparative studies, contributing to the understanding of the importance and level of predation in various habitats worldwide.

PMID- 27686249 TI - Synaptic signalling and plasticity: emerging new players. PMID- 27686250 TI - Dual processing of visual rotation for bipedal stance control. AB - KEY POINTS: When standing, the gain of the body-movement response to a sinusoidally moving visual scene has been shown to get smaller with faster stimuli, possibly through changes in the apportioning of visual flow to self motion or environment motion. We investigated whether visual-flow speed similarly influences the postural response to a discrete, unidirectional rotation of the visual scene in the frontal plane. Contrary to expectation, the evoked postural response consisted of two sequential components with opposite relationships to visual motion speed. With faster visual rotation the early component became smaller, not through a change in gain but by changes in its temporal structure, while the later component grew larger. We propose that the early component arises from the balance control system minimising apparent self-motion, while the later component stems from the postural system realigning the body with gravity. ABSTRACT: The source of visual motion is inherently ambiguous such that movement of objects in the environment can evoke self-motion illusions and postural adjustments. Theoretically, the brain can mitigate this problem by combining visual signals with other types of information. A Bayesian model that achieves this was previously proposed and predicts a decreasing gain of postural response with increasing visual motion speed. Here we test this prediction for discrete, unidirectional, full-field visual rotations in the frontal plane of standing subjects. The speed (0.75-48 deg s(-1) ) and direction of visual rotation was pseudo-randomly varied and mediolateral responses were measured from displacements of the trunk and horizontal ground reaction forces. The behaviour evoked by this visual rotation was more complex than has hitherto been reported, consisting broadly of two consecutive components with respective latencies of ~190 ms and >0.7 s. Both components were sensitive to visual rotation speed, but with diametrically opposite relationships. Thus, the early component decreased with faster visual rotation, while the later component increased. Furthermore, the decrease in size of the early component was not achieved by a simple attenuation of gain, but by a change in its temporal structure. We conclude that the two components represent expressions of different motor functions, both pertinent to the control of bipedal stance. We propose that the early response stems from the balance control system attempting to minimise unintended body motion, while the later response arises from the postural control system attempting to align the body with gravity. PMID- 27686251 TI - Evaluation of injectable robenacoxib for the treatment of post-operative pain in cats: results of a randomized, masked, placebo-controlled clinical trial. AB - BACKGROUND: Few pharmaceuticals are registered in cats for the management of post operative pain and inflammation. The objective of this study was to assess the field efficacy and safety of an injectable formulation of the nonsteroidal anti inflammatory drug robenacoxib in cats undergoing surgery. The study was a multi center, prospective, randomized, masked, parallel-group, placebo-controlled clinical trial. A total of 349 cats were enrolled and underwent surgery comprising forelimb onychectomy, as an example of orthopedic surgery, plus either ovariohysterectomy or castration. All cats received butorphanol prior to anesthesia and forelimb four-point regional nerve blocks with bupivacaine after induction of general anesthesia. Cats were randomized to receive daily subcutaneous (s.c.) injection of robenacoxib, at a target dosage of 2.0 mg/kg (n = 174), or placebo (n = 175) once prior to surgery and for an additional two days post-operatively. RESULTS: Significantly (P = 0.037) fewer cats administered robenacoxib received additional analgesia rescue therapy (34 of 173, 19.7 %) compared to cats given placebo (73 of 175, 41.7 %). The percentage of treatment success was therefore 80.3 % with robenacoxib and 58.3 % with placebo. Behavior, posture, pain on palpation of the paw and soft tissue surgery sites, and overall pain were significantly (P < 0.05) improved versus placebo at various time points within the first 8 h in cats receiving robenacoxib. The most frequently reported adverse events were incision site infection/dehiscence, bleeding, vomiting, decreased appetite and lethargy. Frequencies of reported adverse clinical signs, hematology, serum chemistry and urinalysis variables, and body weight changes were similar between groups. There were no significant changes from baseline with robenacoxib in hepatic, hematological or renal clinical pathology variables. CONCLUSIONS: Robenacoxib by s.c. injection was effective and well tolerated in the control of post-operative pain associated with orthopedic, ovariohysterectomy and castration surgery in cats. PMID- 27686252 TI - Successful thrombolysis with recombinant tissue plasminogen activator after antagonizing dabigatran by idarucizumab: a case report. AB - BACKGROUND: Effective anticoagulation routinely precludes patients from receiving intravenous thrombolysis with recombinant tissue plasminogen activator to reverse severe symptoms of ischemic stroke. We report what we believe to be the first case of ischemic stroke successfully treated with recombinant tissue plasminogen activator after antagonizing dabigatran with the monoclonal antibody idarucizumab, recently approved worldwide. CASE PRESENTATION: A 75-year-old Caucasian man presented to our hospital with severe aphasia and mild hemiparesis. After providing written consent, he received two doses of 2.5 g of idarucizumab over 20 minutes followed by standard protocol in-label recombinant tissue plasminogen activator application. All symptoms resolved within 1 h. CONCLUSIONS: Applying a recombinant tissue plasminogen activator after antagonizing dabigatran with idarucizumab is feasible and easy to manage in an emergency room or stroke unit. Thus, idarucizumab represents a new therapeutic option for patients receiving dabigatran treatment, reestablishing their eligibility for recombinant tissue plasminogen activator thrombolysis.

PMID- 27686254 TI - The poly(ADP-ribosyl)ation of FoxO3 mediated by PARP1 participates in isoproterenol-induced cardiac hypertrophy. AB - The Forkhead box-containing protein, O subfamily 3 (FoxO3) transcription factor negatively regulates myocardial hypertrophy, and its transcriptional activity is finely conditioned by diverse posttranslational modifications, such as phosphorylation, acetylation, ubiquitination, methylation and glycosylation. Here, we introduce a novel modification of the FoxO3 protein in cardiomyocytes: poly(ADP-ribosyl)ation (PARylation) mediated by poly(ADP-ribose) polymerase-1 (PARP1). This process catalyzes the NAD+-dependent synthesis of polymers of ADP ribose (PAR) and their subsequent attachment to target proteins by PARPs. Primary cultured neonatal rat cardiomyocytes were incubated with isoproterenol (ISO) to induce hypertrophy, or were infected with recombinant adenovirus vectors harboring PARP1 cDNA (Ad-PARP1). Sprague-Dawley (SD) rats were treated with ISO to induce cardiac hypertrophy, or were injected with Ad-PARP1 into the anterior and posterior left ventricular walls. Cardiomyocyte surface area, the mRNA expression of hypertrophic biomarkers, echocardiography, morphometry of the hearts were measured. The PARP1 activity was tested by cellular PAR levels. Interactions of PARP1 and FoxO3 were investigated by co-immunoprecipitation and immunofluorescence technique. PARylation of FoxO3 mediated by PARP1 facilitated its phosphorylation at the T32, S252 and S314 sites, triggered its nucleus export and suppressed its transcriptional activity and target genes expression, ultimately inducing cardiac hypertrophy. Additionally, PARP1 silencing or specific inhibition by 3-Aminobenzamide (3AB) and veliparib (ABT-888) alleviated the inhibition of FoxO3 activity by ISO, thus suppressing ISO-induced cardiac hypertrophy. Our data provide the first evidence that PARP1 exacerbates cardiac hypertrophy by PARylation of FoxO3. PMID- 27686255 TI - Altered regulation of the Spry2/Dyrk1A/PP2A triad by homocysteine impairs neural progenitor cell proliferation. AB - Hyperhomocysteinemia reduces neurogenesis in the adult mouse brain. Homocysteine (Hcy) inhibits postnatal neural progenitor cell (NPC) proliferation by specifically impairing the fibroblast growth factor receptor (FGFR)-Erk1/2-cyclin E signaling pathway. We demonstrate herein that the inhibition of FGFR-dependent NPC proliferation induced by Hcy is mediated by its capacity to alter the cellular methylation potential. Our results show that this alteration modified the expression pattern and activity of Sprouty2 (Spry2), a negative regulator of the above mentioned pathway. Both elevated concentrations of Hcy and methyltransferase activity inhibition induced Spry2 promoter demethylation in NPC cultures leading to a sustained upregulation of the expression of Spry2 mRNA and protein. In addition, protein levels of two kinases responsible for Spry2 activation/deactivation were altered by Hcy: Spry2 kinase Dyrk1A levels diminished while Spry2 phosphatase PP2A increased, leading to changes in the phosphorylation pattern, activity and stability of Spry2. In conclusion, Hcy inhibits NPC proliferation by indirect mechanisms involving alterations in DNA methylation, gene expression, and Spry2 function, causing FGFR signaling impairment. PMID- 27686256 TI - Further evidence of early development of attention to dynamic facial emotions: Reply to Grossmann and Jessen. AB - Adults exhibit enhanced attention to negative emotions like fear, which is thought to be an adaptive reaction to emotional information. Previous research, mostly conducted with static faces, suggests that infants exhibit an attentional bias toward fearful faces only at around 7months of age. In a recent study (Journal of Experimental Child Psychology, 2016, Vol. 147, pp. 100-110), we found that 5-month-olds also exhibit heightened attention to fear when tested with dynamic face videos. This indication of an earlier development of an attention bias to fear raises questions about developmental mechanisms that have been proposed to underlie this function. However, Grossmann and Jessen (Journal of Experimental Child Psychology, 2016, Vol. 153, pp. 149-154) argued that this result may have been due to differences in the amount of movement in the videos rather than a response to emotional information. To examine this possibility, we tested a new sample of 5-month-olds exactly as in the original study (Heck, Hock, White, Jubran, & Bhatt, 2016) but with inverted faces. We found that the fear bias seen in our study was no longer apparent with inverted faces. Therefore, it is likely that infants' enhanced attention to fear in our study was indeed a response to emotions rather than a reaction to arbitrary low-level stimulus features. This finding indicates enhanced attention to fear at 5months and underscores the need to find mechanisms that engender the development of emotion knowledge early in life.

PMID- 27686258 TI - Understanding Technology and People Issues in Hospital Information System (HIS) Adoption: Case study of a tertiary hospital in Malaysia. AB - BACKGROUND: Hospital Information Systems (HIS) can improve healthcare outcome quality, increase efficiency, and reduce errors. The government of Malaysia implemented HIS across the country to maximize the use of technology to improve healthcare delivery, however, little is known about the benefits and challenges of HIS adoption in each institution. This paper looks at the technology and people issues in adopting such systems. METHODS: The study used a case study approach, using an in-depth interview with multidisciplinary medical team members who were using the system on a daily basis. A thematic analysis using Atlas.ti was employed to understand the complex relations among themes and sub-themes to discover the patterns in the data. . RESULTS: Users found the new system increased the efficiency of workflows and saved time. They reported less redundancy of work and improved communication among medical team members. Data retrieval and storage were also mentioned as positive results of the new HIS system. Healthcare workers showed positive attitudes during training and throughout the learning process. CONCLUSIONS: From a technological perspective, it was found that medical workers using HIS has better access and data management compared to the previously used manual system. The human issues analysis reveals positive attitudes toward using HIS among the users especially from the physicians' side. PMID- 27686259 TI - Local deformation fields and marginal integrity of sculptable bulk-fill, low shrinkage and conventional composites. AB - OBJECTIVE: To compare strain and displacement of sculptable bulk-fill, low shrinkage and conventional composites as well as dye penetration along the dentin restoration interface. METHODS: Modified Class II cavities (N=5/group) were filled with sculptable bulk-fill (Filtek Bulk Fill Posterior, 3M ESPE; Tetric EvoCeram Bulk Fill, Ivoclar Vivadent; fiber-reinforced EverX Posterior, GC; giomer Beautifil Bulk, Schofu), low-shrinkage (Kalore, GC), nanohybrid (Tetric EvoCeram, Ivoclar Vivadent) or microhybrid (Filtek Z250, 3M ESPE) composites. Strain and displacement were determined using the 3D digital image correlation method based on two cameras with 1MUm displacement sensitivity and 1600*1200 pixel resolution (Aramis, GOM). Microleakage along dentin axial and gingival cavity walls was measured under a stereomicroscope using a different set of teeth (N=8/group). Data were analyzed using analyses of variance with Tukey's post test, Pearson correlation and paired t-test (alpha=0.05). RESULTS: Strain of TEC Bulk, Filtek Bulk, Beautifil Bulk and Kalore was in the range of 1-1.5%. EverX and control composites showed 1.5-2% strain. Axial displacements were between 5MUm and 30MUm. The least strain was identified at 2mm below the occlusal surface in 4-mm but not in 2-mm layered composites. Greater microleakage occurred along the gingival than axial wall (p<0.05). No correlation was found between strain/displacements and microleakage axially (r2=0.082, p=0.821; r2=-0.2, p=0.605, respectively) or gingivally (r2=-0.126, p=0.729, r2=-0.278, p=0.469, respectively). SIGNIFICANCE: Strain i.e. volumetric shrinkage of sculptable bulk fill and low-shrinkage composites was comparable to control composites but strain distribution across restoration depth differed. Marginal integrity was more compromised along the gingival than axial dentin wall. PMID- 27686260 TI - Bioactivity and biocompatibility of two fluoride containing bioactive glasses for dental applications. AB - OBJECTIVE: Bioactive glasses (BAG) form, in contrast to formerly used implant materials, a stable bond with tissues, especially bone, when implanted. Nowadays BAGs are often mixed with a cement/composite that hardens in situ to broaden its applications in dentistry or orthopedics. The bioactivity and biocompatibility of possible BAG candidates for BAG-cement/composite development were evaluated. METHODS: Two fluoride containing BAGs were tested: a Na+-containing (45S5F), based on the first commercial BAG, and a Na+-free BAG (CF9), with a higher Ca2+ and PO43- content. BAGs were tested on their bioactivity upon immersion in SBF for 7days by evaluating the surface changes by FT-IR, SEM, EDS and PO43- and Ca2+ uptake and/or release from SBF. Moreover, the biocompatibility of the BAGs was investigated with a direct contact cell viability study with HFF cells and a cell adhesion study with MG-63 cells. RESULTS: The Na+-free BAG, CF9, showed the highest potential to bioactivate cements because of its high Ca2+-release and apatite (Ap) formation, as evidenced by SEM pictures and corresponding EDX patterns. FT-IR confirmed the formation of an Ap layer. Moreover CF9 had a higher biocompatibility than 45S5F. SIGNIFICANCE: For the bioactivation of GICs/composites in order to enhance bonding and remineralization of surrounding tissues, fluoride containing BAG may have advantages over other BAGs as a more stable fluorapatite can be formed. CF9 may be an excellent candidate therefore. PMID- 27686261 TI - Down the Rabbit Hole-Carrots, Genetics and Art.

AB - The Oriental fruit moth, Grapholita molesta (Lepidoptera: Tortricidae), is a major pest of fruit trees worldwide, such as peach and apple. Bacillus thuringiensis has been shown to be an efficient alternative to synthetic insecticides in the control of many agricultural pests. The objective of this study was to evaluate the effectiveness of B. thuringiensis individual toxins and their mixtures for the control of G. molesta. Bioassays were performed with Cry1Aa, Cry1Ac, Cry1Ca, Vip3Aa, Vip3Af and Vip3Ca, as well as with the commercial products DiPel(r) and XenTari(r). The most active proteins were Vip3Aa and Cry1Aa, with LC50 values of 1.8 and 7.5ng/cm2, respectively. Vip3Ca was nontoxic to this insect species. Among the commercial products, DiPel(r) was slightly, but significantly, more toxic than XenTari(r), with LC50 values of 13 and 33ng commercial product/cm2, respectively. Since Vip3A and Cry1 proteins are expressed together in some insect-resistant crops, we evaluated possible synergistic or antagonistic interactions among them. The results showed moderate to high antagonism in the combinations of Vip3Aa with Cry1Aa and Cry1Ca.

AB - BACKGROUND AND STUDY AIMS: Polymorphisms in the DNA repair genes may influence individual capacity to repair DNA damage, which may be associated with increased genetic instability and carcinogenesis. Our aim was to evaluate the relation of genetic polymorphisms in 2 DNA repair genes, XPD Lys751Gln and XRCC1 (A399G), with colorectal cancer (CRC) susceptibility. We further investigated the potential effect of these DNA repair variants on clinicopathological parameters of CRC patients. PATIENTS AND METHODS: Both XPD and XRCC1 polymorphisms were characterised in one hundred CRC patients and one hundred healthy controls who had no history of any malignancy by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method and PCR with confronting two-pair primers (PCR-CTPP), using DNA from peripheral blood in a case control study. RESULTS: Our results revealed that the frequencies of GG genotype of XRCC1 399 polymorphism were significantly higher in the CRC patients than in the normal individuals (p?0.03), and did not observe any association between the XPD Lys751Gln polymorphism and CRC risk. We found association between both XRCC1 A399G polymorphisms and histological grading of disease. CONCLUSION: Our results suggested that, XRCC1 gene is an important candidate gene for susceptibility to colorectal carcinoma. PMID- 27686264 TI - Single incision laparoscopic appendicectomy versus conventional three-port laparoscopic appendicectomy: A systematic review and meta-analysis. AB - BACKGROUND: Appendicectomy is a well-established surgical procedure used in the management of acute appendicitis. The operation can be performed with minimally invasive surgery or as an open procedure. A further development in the minimally invasive appendicectomy technique has been the introduction of single incision laparoscopic surgery (SILA). AIM: To ascertain any differences in outcomes from available trials comparing SILA with conventional multi-incision laparoscopic appendicectomy (CLA). METHODS: A literature search of MEDLINE/PubMed, EMBASE/Ovid and CENTRAL for articles from Jan1990 to June 2015 with key words: 'appendectomy', 'appendicetomy'; 'appendicitis'; 'laparoscopy'; 'keyhole'; 'single port'; 'single incision'; 'single site'; 'one port'; 'incisionless'; 'scarless'. Randomised control trials of patients with signs and symptoms of appendicitis undergoing laparoscopic appendicectomy, with one arm being SILA were included. Statistical analysis was performed through Mantle-Haenszel and inverse variance methods. RESULTS: A total of 8 RCTs published between 2012 and 2014 with a total of 995 patients were included. Meta-analysis showed no significant differences between SILA and CLA for complication rates, post-operative ileus, length of hospital stay, return to work or post-operative pain. CLA was significantly superior to SILA with reduced operating time (mean difference 5.81 [2.01, 9.62] P = 0.003) and conversion rates (OR 4.14 [1.93, 8.91] P = 0.0003). SILA surgery had better wound cosmesis (mean difference 0.55 [0.33, 0.77] P = 0.00001). CONCLUSION: SILA is comparable to CLA in terms of complications, post operative pain and recovery. Therefore, SILA could be a viable option in the hands of an experienced surgeons and for patients' groups who place great value on the final cosmetic outcome.

PMID- 27686266 TI - Optimizing antibiotic usage in hospitals: a qualitative study of the perspectives of hospital managers. AB - BACKGROUND: Antibiotic optimization in hospitals is an increasingly critical priority in the context of proliferating resistance. Despite the emphasis on doctors, optimizing antibiotic use within hospitals requires an understanding of how different stakeholders, including non-prescribers, influence practice and practice change. AIM: This study was designed to understand Australian hospital managers' perspectives on antimicrobial resistance, managing antibiotic governance, and negotiating clinical vis-a-vis managerial priorities. METHODS: Twenty-three managers in three hospitals participated in qualitative semi structured interviews in Australia in 2014 and 2015. Data were systematically coded and thematically analysed. FINDINGS: The findings demonstrate, from a managerial perspective: (1) competing demands that can hinder the prioritization of antibiotic governance; (2) ineffectiveness of audit and monitoring methods that limit rationalization for change; (3) limited clinical education and feedback to doctors; and (4) management-directed change processes are constrained by the perceived absence of a 'culture of accountability' for antimicrobial use amongst doctors. CONCLUSION: Hospital managers report considerable structural and interprofessional challenges to actualizing antibiotic optimization and governance. These challenges place optimization as a lower priority vis-a-vis other issues that management are confronted with in hospital settings, and emphasize the importance of antimicrobial stewardship (AMS) programmes that engage management in understanding and addressing the barriers to change. PMID- 27686267 TI - Vaccine profile of PPV23: Beijing Minhai Biotech 23-valent pneumococcal vaccine. AB - INTRODUCTION: Diseases caused by Streptococcus pneumoniae are a major public health problem worldwide, which can be effectively prevented by the 23-valent pneumococcal polysaccharide vaccines (PPV23). Areas covered: The Beijing Minhai PPV23 showed good safety and immunogenicity profiles in clinical trials. The immunogenicity of Beijing Minhai PPV23 was non-inferior to other licensed PPVs. Although PPV23 has been proved to be highly efficient and cost-effective, and was recommended for vaccination in high-risk populations in industrialized countries, the coverage of PPV23 vaccination was relatively low in developing countries. Expert commentary: The low vaccination proportions of PPV23 in China have not been improved in recent decades. Most of the populations with indications for receiving PPV23 were not aware of the possible benefits of PPV23. Moreover, PPV23 had some limitations, which called for the development of a new generation of vaccines against pneumococcal infection. PMID- 27686268 TI - Symplocos cochinchinensis enhances insulin sensitivity via the down regulation of lipogenesis and insulin resistance in high energy diet rat model. AB - ETHNOPHARMACOLOGICAL RELEVANCE: This plant has been utilized in Indian system of medicine for treatment of diabetes. This is clearly evident from the composition of Ayurvedic preparation for diabetes 'Nisakathakadi Kashayam' where this is one of the main ingredients of this preparation AIM OF THE STUDY: The study aims in elucidating the molecular mechanisms underlying the insulin sensitizing effects of Symplocos cochinchinensis ethanol extract (SCE) using a high fructose and saturated fat (HFS) fed insulin resistant rat model. MATERIALS AND METHODS: Experimental groups consisted of normal diet (ND), ND+SCE 500mg/kg bwd, HFS+vehicle, HFS+metformin 100mg/kg bwd, HFS+SCE 250/500mg/kg bwd. Initially the animals were kept under HFS diet for 8 weeks, and at the end of 8 week period, animals were found to develop insulin resistance and dyslipidemia. Post administration of SCE, metformin or vehicle were carried out for 3 weeks. Gene and protein expressions relevant to insulin signalling pathway were analysed. RESULTS: HFS significantly altered the normal physiology of animals via proteins and genes relevant to metabolism like stearoyl-CoA desaturase (SCD1), sterol regulatory element binding protein 1 (SREBP-1c), fatty acid synthase (FAS), glucose 6 phosphatase (G6Pase), phosphoenol pyruvate carboxykinase (PEPCK), glucose transporter 2 (GLUT2), protein tyrosine phosphatse 1B (PTP1B), peroxisome proliferator activated receptor alpha (PPAR alpha), sirtuin 1 (SIRT1) and glucokinase. SCE administration attenuates the insulin resistance in HFS rat by the down regulation of SCD1 gene expression that modulates SREBP-1c dependent and independent hepatic lipid accumulation. CONCLUSION: SCE enhances insulin sensitivity via the down regulation of lipogenesis and insulin resistance in HFS rat model. PMID- 27686269 TI - Phytochemical and ethnomedicinal study of Huperzia species used in the traditional medicine of Saraguros in Southern Ecuador; AChE and MAO inhibitory activity. AB - ETHNOBOTANICAL AND ETHNOMEDICINAL RELEVANCE: This study concerns seven Huperzia species (Lycopodiaceae), namely H. brevifolia, H. columnaris, H. compacta, H. crassa, H. espinosana, H. tetragona, H. weberbaueri, which are considered sacred plants by the Saraguro community, living in the Southern Andes of Ecuador; these plants are widely used in traditional medicine and ritual ceremonies. MATERIAL AND METHODS: The plants were selected on the basis of written interviews with 10 visionary healers (yachak) (2 women, 8 men), indicated as the most credible by the Saraguro Healers Council. The Informant Consensus Factor (Fic) was determined. The first phytochemical study of the plants was performed by standard procedures, while the AChE and MAO-A inhibition by fractions enriched in high MW alkaloids, was measured in vitro. AIMS OF THE STUDY: i) to investigate the uses of some Huperzia plants in healing and magical-religious practices of Saraguros; ii) to identify the main components of plant hydromethanolic extracts; iii) to test the effects of alkaloidal fractions on the activity of two enzymes linked to mental health. RESULTS: All the interviewed Saraguro yachak showed a high consensus about the uses of the seven Huperzia plants as purgatives and against supernatural diseases, such as the "espanto" (startle). In admixtures with other plants, some species also induce a state of trance or hallucinations in participants in magical-religious rituals. GC-MS of the volatile alkaloid fractions allowed the identification of some lycodine-type and lycopodine-type alkaloids (1-5) in H. compacta, H. columnaris, and H. tetragona. The flavones selgin) (6) and tricin (7) were isolated from H. brevifolia and H. espinosana. Tricin (7) was also detected in the other five species. The rare serratene triterpenes serratenediol (8) serratenediol-3-O-acetate (9), 21-episerratenediol (10), and 21-episerratenediol-3-O-acetate (11) were isolated from H. crassa. In addition, the presence of an unprecedented group of high molecular weight alkaloids has been determined. Alkaloid fractions of H. brevifolia, H. compacta, H. espinosana, and H. tetragona significantly inhibited AChE and MAO-A activities in vitro. CONCLUSIONS: The first phytochemical and ethnopharmacological study of seven Huperzia plants, widely used by Saraguro healers, led to the identification of several alkaloids and triterpenoids with different remarkable biological activities. In addition, alkaloid fractions exhibited a significant AChE and MAO A inhibitory activity. These results may support the use of these plants in brews prepared for inducing psychoactive effects in participants in magical-religious ceremonies. This study confirms the rich traditional medical knowledge of Saraguro healers which must be documented and preserved for future generations. PMID- 27686270 TI - Three indigenous plants used in anti-cancer remedies, Garcinia kola Heckel (stem bark), Uvaria chamae P. Beauv. (root) and Olax subscorpioidea Oliv. (root) show analgesic and anti-inflammatory activities in animal models. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Phytochemicals with anti-oxidative and anti inflammatory properties are known to inhibit tumour initiation, promotion and progression. Hence, there is an increasingly-convincing rationale for employing remedies containing those phytochemicals in the treatment of cancers and also as analgesic and anti-inflammatory adjuvants in therapy. The plants Garcinia kola Heckel (Clusiaceae), stem bark; Uvaria chamae P. Beauv. (Annonaceae), root; and Olax subscorpioidea Oliv. (Olacaceae), root, have been documented to be part of various indigenous anti-cancer regimens. AIM OF THE STUDY: To determine if the three plants exhibit significant anti-oxidative and anti-inflammatory properties. MATERIALS AND METHODS: Using established models, the analgesic and anti inflammatory activities of the three plants were investigated. RESULTS: Pre treatment with the plant extracts at 100, 200 and 400mg/kg produced inhibition of writhes; G. kola and U. chamae showed no significant effect on formalin-induced pain, but O. subscorpioidea produced inhibition in both phases of the formalin test. Similarly, while G. kola and U. chamae did not produce any significant inhibitory effect in the xylene-induced ear oedema model, the oedema was significantly reduced by O. subscorpioidea pre-treatment. However, all the three plants significantly inhibited the time-dependent increase in paw circumference in the carrageenan- and formaldehyde-induced rat paw oedema tests, with peak effects observed at 400mg/kg, 6h after the induction of oedema, comparable in some cases to the effects of two standard drugs, the non-steroidal anti inflammatory drug diclofenac and the anti-inflammatory antibiotic doxycycline. CONCLUSION: We conclude that the three plant extracts possess analgesic and anti inflammatory properties, thus providing a scientific rationale for their inclusion in some traditional anti-cancer regimens. PMID- 27686271 TI - Bufalin inhibits pancreatic cancer by inducing cell cycle arrest via the c-Myc/NF kappaB pathway. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Bufalin, a cardiotonic steroid isolated from toad venom (bufo gargarizans Cantor or B. melanotictus Schneider), has widely demonstrated antitumor effects and exhibits potential antitumor activity in various human cancer cells lines. AIMS OF THE STUDY: The main characteristic of cancers including pancreatic cancer is the ability of uncontrolled proliferation. The aim of this study is to clarify the underlying mechanism by which bufalin inhibits pancreatic cancer cell proliferation. MATERIALS AND METHODS: The effect of bufalin on the suppression of tumor growth in vivo was studied in a bioluminescent mouse model generated using the pancreatic cancer cell line BxPC3 luc2 and the cytotoxicity was evaluated in BcPc3 and Sw1990 cells with MTT. Flow cytometry and western blotting analyses were utilized to detect the effect of bufalin on the cell cycle and to detect the cell cycle-related proteins, respectively. Then, a luciferase reporter assay was applied to screen the activity of potent transcription factors following bufalin exposure and their expression was detected by western blotting. RESULTS: Bufalin suppressed tumor growth in a bioluminescence mouse model generated using BxPC3-luc2 cells and inhibited cell proliferation in vitro through inducing cell cycle arrest at S phase. Bufalin treatment inhibited cyclin D1 and cyclin E1 expression and therefore increased expression of p27, a regulatory molecular that controls cell cycle transition from S to G2 phase. Furthermore, luciferase reporter screening studies revealed that bufalin inhibited the expression and activity of the transcription factors c-Myc and NF-kappaB, which might cause cell cycle arrest at S phase and the inhibition of cell proliferation. CONCLUSIONS: Taken together, our results indicate that bufalin can inhibit pancreatic cancer by targeting c Myc, thus suggesting that the mechanism of c-Myc regulation by bufalin might be worthy of further study regarding its potential as a therapeutic target for pancreatic cancer treatment.

AB - Identifying appropriate molecular targets is a critical step in drug development. Despite many advantages, the traditional tools of observational epidemiology and cellular or animal models of disease can be misleading in identifying causal pathways likely to lead to successful therapeutics. Here, we review some favorable aspects of human genetics studies that have the potential to accelerate drug target discovery. These include using genetic studies to identify pathways relevant to human disease, leveraging human genetics to discern causal relationships between biomarkers and disease, and studying genetic variation in humans to predict the potential efficacy and safety of inhibitory compounds aimed at molecular targets. We present some examples taken from studies of plasma lipids and coronary artery disease to highlight how human genetics can accelerate therapeutics development. PMID- 27686274 TI - The ordered assembly of tau is the gain-of-toxic function that causes human tauopathies. AB - A pathological pathway leading from soluble to insoluble and filamentous tau underlies human tauopathies. This ordered assembly causes disease and is the gain of-toxic function. It involves the transition from an intrinsically disordered monomer to a highly structured filament. Based on recent findings, one can divide the ordered assembly into propagation of pathology and neurodegeneration. Short tau fibrils constitute the major species of seed-competent tau in the brains of mice transgenic for human P301S tau. The molecular species of aggregated tau that are essential for neurodegeneration remain to be identified. PMID- 27686275 TI - The development of the spatially correlated adjustment wavelet filter for atomic force microscopy data. AB - In this paper a novel approach for the practical utilization of the 2D wavelet filter in terms of the artifacts removal from atomic force microscopy measurements results is presented. The utilization of additional data such as summary photodiode signal map is implemented in terms of the identification of the areas requiring the data processing, filtering settings optimization and the verification of the process performance. Such an approach allows to perform the filtering parameters adjustment by average user, while the straightforward method requires an expertise in this field. The procedure was developed as the function of the Gwyddion software. The examples of filtering the phase imaging and Electrostatic Force Microscopy measurement result are presented. As the wavelet filtering feature may remove a local artifacts, its superior efficiency over similar approach with 2D Fast Fourier Transformate based filter (2D FFT) can be noticed. PMID- 27686276 TI - Dependence of the volume of an antibody on the force applied in a force microscopy experiment in liquid. AB - The volume of a protein can be estimated from its molecular weight. This approach has also been applied in force microscopy experiments. Two factors contribute to the determination of the volume from a force microscope image, the applied force and the tip radius. Those factors act in opposite directions. Here, we demonstrate that in the optimum conditions to image a protein, the apparent volume deduced from an AFM image overestimates the real protein volume. The lateral broadening due to the tip finite size, makes the simulated volume to exceed the real protein volume value, while the force applied by the tip tends to decrease the measured volume. The measured volume could coincide with the real volume for either a point-size tip at zero force or when the compression exerted by the tip compensates its dilation effects. The interplay between the above factors make unsuitable to apply the molecular weight method to determine the volume of a protein from AFM data. PMID- 27686277 TI - Temporal course of gene expression during motor memory formation in primary motor cortex of rats. AB - Motor learning is associated with plastic reorganization of neural networks in primary motor cortex (M1) that depends on changes in gene expression. Here, we investigate the temporal profile of these changes during motor memory formation in response to a skilled reaching task in rats. mRNA-levels were measured 1h, 7h and 24h after the end of a training session using microarray technique. To assure learning specificity, trained animals were compared to a control group. In response to motor learning, genes are sequentially regulated with high time-point specificity and a shift from initial suppression to later activation. The majority of regulated genes can be linked to learning-related plasticity. In the gene-expression cascade following motor learning, three different steps can be defined: (1) an initial suppression of genes influencing gene transcription. (2) Expression of genes that support translation of mRNA in defined compartments. (3) Expression of genes that immediately mediates plastic changes. Gene expression peaks after 24h - this is a much slower time-course when compared to hippocampus dependent learning, where peaks of gene-expression can be observed 6-12h after training ended. PMID- 27686278 TI - Deficient fear extinction memory in posttraumatic stress disorder. AB - BACKGROUND: Posttraumatic stress disorder (PTSD) might be maintained by deficient extinction memory. We used a cued fear conditioning design with extinction and a post-extinction phase to provoke the return of fear and examined the role of the interplay of amygdala, hippocampus and prefrontal regions. METHODS: We compared 18 PTSD patients with two healthy control groups: 18 trauma-exposed subjects without PTSD (nonPTSD) and 18 healthy controls (HC) without trauma experience. They underwent a three-day ABC-conditioning procedure in a functional magnetic resonance imaging scanner. Two geometric shapes that served as conditioned stimuli (CS) were presented in the context of virtual reality scenes. Electric painful stimuli were delivered after one of the two shapes (CS+) during acquisition (in context A), while the other (CS-) was never paired with pain. Extinction was performed in context B and extinction memory was tested in a novel context C. RESULTS: The PTSD patients showed significantly higher differential skin conductance responses than the non-PTSD and HC and higher differential amygdala and hippocampus activity than the HC in context C. In addition, elevated arousal to the CS+ during extinction and to the CS- throughout the experiment was present in the PTSD patients but self-reported differential valence or contingency were not different. During extinction recall, differential amygdala activity correlated positively with the intensity of numbing and ventromedial prefrontal cortex activity correlated positively with behavioral avoidance. CONCLUSIONS: PTSD patients show heightened return of fear in neural and peripheral measures. In addition, self-reported arousal was high to both danger (CS+) and safety (CS-) cues. These results suggest that a deficient maintenance of extinction and a failure to identify safety signals might contribute to PTSD symptoms, whereas non-PTSD subjects seem to show normal responses. PMID- 27686279 TI - Do adverse perinatal events predict mortality in schizophrenia during midlife? AB - BACKGROUND: We examined mortality in schizophrenia spectrum disorder (SSD) and non-schizophrenic psychosis (NSSD) compared to individuals without psychosis, and whether perinatal factors predict mortality. METHODS: Within Northern Finland Birth Cohort 1966 (n=10 933; 203 with SSD, 178 with NSSD), mortality was followed until end of 2011 by national register. Wantedness of pregnancy, mother's antenatal depression, smoking and age, parity, paternal socio-economic status (SES) and family type at birth were examined as predictors of mortality. RESULTS: Mortality was higher in SSD (hazard ratio (HR) 3.60; 95% confidence interval (CI) 2.38-5.45) and NSSD (4.05; 2.65-6.17) compared to persons without psychoses after adjustment for gender. HR for natural death was 2.01 (0.82-4.91) in SSD and 4.63 (2.43-8.80) in NSSD after adjustment for gender. Corresponding figures for unnatural deaths were 4.71 (2.94-7.54) and 2.94 (1.56-5.55), respectively. Among non-psychotic persons, mother's depression, smoking and low SES predicted mortality after adjustment for gender and parental psychoses (and SES), whereas among psychosis those whose father was a farmer had lower risk of mortality compared to those with high SES. CONCLUSIONS: Individuals with SSD had a higher risk of unnatural death and individuals with NSSD of natural and unnatural deaths. Perinatal factors seem to be more important predictors of mortality in individuals without psychoses than with psychoses. According to population-based long follow-up data, it is important to pay attention to somatic morbidity behind natural causes of death in psychoses and to prevent suicides in order to prevent excess mortality. PMID- 27686280 TI - Conservation and Variability of Meiosis Across the Eukaryotes. AB - Comparisons among a variety of eukaryotes have revealed considerable variability in the structures and processes involved in their meiosis. Nevertheless, conventional forms of meiosis occur in all major groups of eukaryotes, including early-branching protists. This finding confirms that meiosis originated in the common ancestor of all eukaryotes and suggests that primordial meiosis may have had many characteristics in common with conventional extant meiosis. However, it is possible that the synaptonemal complex and the delicate crossover control related to its presence were later acquisitions. Later still, modifications to meiotic processes occurred within different groups of eukaryotes. Better knowledge on the spectrum of derived and uncommon forms of meiosis will improve our understanding of many still mysterious aspects of the meiotic process and help to explain the evolutionary basis of functional adaptations to the meiotic program. PMID- 27686281 TI - The Ecology and Evolution of Cancer: The Ultra-Microevolutionary Process. AB - Although tumorigenesis has been accepted as an evolutionary process ( 20 , 102 ), many forces may operate differently in cancers than in organisms, as they evolve at vastly different time scales. Among such forces, natural selection, here defined as differential cellular proliferation among distinct somatic cell genotypes, is particularly interesting because its action might be thwarted in multicellular organisms ( 20 , 29 ). In this review, selection is analyzed in two stages of cancer evolution: Stage I is the evolution between tumors and normal tissues, and Stage II is the evolution within tumors. The Cancer Genome Atlas (TCGA) data show a low degree of convergent evolution in Stage I, where genetic changes are not extensively shared among cases. An equally important, albeit much less highlighted, discovery using TCGA data is that there is almost no net selection in cancer evolution. Both positive and negative selection are evident but they neatly cancel each other out, rendering total selection ineffective in the absence of recombination. The efficacy of selection is even lower in Stage II, where neutral (non-Darwinian) evolution is increasingly supported by high density sampling studies ( 81 , 123 ). Because natural selection is not a strong deterministic force, cancers usually evolve divergently even in similar tissue environments. PMID- 27686282 TI - Electrocardiographic surveillance in a psychiatric institution: avoiding iatrogenic cardiovascular death. AB - OBJECTIVE: To describe a new initiative developed to optimise patient safety in a mental health setting in order to prevent serious cardiac events. MATERIALS AND METHODS: A longitudinal study of all in-patients admitted at the hospital, comprised of 197 beds distributed among three units, was conducted for 12 months. All admitted patients at the hospital underwent electrocardiogram surveillance, as it was described in our new local guideline for sudden cardiac death prevention. When electrocardiographic alterations were detected, treating physicians searched for patient's risk factors and suspicious medication and communicated the adverse event to the Pharmacy Department. These data were registered in electronic medical record system. RESULTS: Over the 12-month study period, 225 patients were evaluated and 9 cases (4%) of long QT segment were detected. A multidisciplinary evaluation was done and it resulted in treatment modification and patient close monitoring. No sudden cardiac deaths occurred during the study period. Drugs more often involved in QT segment prolongation were: olanzapine, clomipramine, clozapine and risperidone. CONCLUSION: QT segment interval enlargement is a frequent clinical problem that affects patients with mental pathology. This inexpensive initiative has allowed identifying patients at risk of sudden cardiac death and has helped to avoid mayor side effects. PMID- 27686283 TI - Safety and immunogenicity of a combined Tetanus, Diphtheria, recombinant acellular Pertussis vaccine (TdaP) in healthy Thai adults. AB - BACKGROUND: An acellular Pertussis (aP) vaccine containing recombinant genetically detoxified Pertussis Toxin (PTgen), Filamentous Hemagglutinin (FHA) and Pertactin (PRN) has been developed by BioNet-Asia (BioNet). We present here the results of the first clinical study of this recombinant aP vaccine formulated alone or in combination with tetanus and diphtheria toxoids (TdaP). METHODS: A phase I/II, observer-blind, randomized controlled trial was conducted at Mahidol University in Bangkok, Thailand in healthy adult volunteers aged 18-35 y. The eligible volunteers were randomized to receive one dose of either BioNet's aP or Tetanus toxoid-reduced Diphtheria toxoid-acellular Pertussis (TdaP) vaccine, or the Tdap Adacel(r) vaccine in a 1:1:1 ratio. Safety follow-up was performed for one month. Immunogenicity was assessed at baseline, at 7 and 28 d after vaccination. Anti-PT, anti-FHA, anti-PRN, anti-tetanus and anti-diphtheria IgG antibodies were assessed by ELISA. Anti-PT neutralizing antibodies were assessed also by CHO cell assay. RESULTS: A total of 60 subjects (20 per each vaccine group) were enrolled and included in the safety analysis. Safety laboratory parameters, incidence of local and systemic post-immunization reactions during 7 d after vaccination and incidence of adverse events during one month after vaccination were similar in the 3 vaccine groups. One month after vaccination, seroresponse rates of anti-PT, anti-FHA and anti-PRN IgG antibodies exceeded 78% in all vaccine groups. The anti-PT IgG, anti-FHA IgG, and anti-PT neutralizing antibody geometric mean titers (GMTs) were significantly higher following immunization with BioNet's aP and BioNet's TdaP than Adacel(r) (P< 0.05). The anti-PRN IgG, anti-tetanus and anti-diphtheria GMTs at one month after immunization were comparable in all vaccine groups. All subjects had seroprotective titers of anti-tetanus and anti-diphtheria antibodies at baseline. CONCLUSION: In this first clinical study, PTgen-based BioNet's aP and TdaP vaccines showed a similar tolerability and safety profile to Adacel(r) and elicited significantly higher immune responses to PT and FHA. PMID- 27686284 TI - The harmonization process to set up and maintain an operational biological and physical retrospective dosimetry network: QA QM applied to the RENEB network. AB - PURPOSE: The European Network of Biological and Physical Retrospective Dosimetry 'RENEB' has contributed to European radiation emergency preparedness. To give homogeneous dose estimation results, RENEB partners must harmonize their processes. MATERIALS AND METHODS: A first inter-comparison focused on biological and physical dosimetry was used to detect the outliers in terms of dose estimation. Subsequently, trainings were organized to improve both tools dose estimation. A second inter-comparison was performed to validate training efficiency. Simultaneously, based on ISO standards, a QA&QM manual on all dosimetry assays was produced which states a common basis and harmonized procedures for each assay. The evaluation of the agreement of RENEB partners to follow the QA&QM manual was performed through a questionnaire. The integration of new members into the network was carried out in the same way, whatever the assays. RESULTS: The training courses on biological and physical dosimetry were judged to be successful because most of the RENEB members' dose estimates improved in the second inter-comparison. The QA&QM manual describes the consensus for the minimum requirements and the performance criteria for both dosimetry assays. The questionnaire revealed that the whole network capacity currently can manage between 15 and 3800 samples once. CONCLUSION: The methodology used to harmonize all dosimetry practice within the network RENEB was highly successful. The network is operational to manage a mass casualty radiation accident for immediate dose assessment. PMID- 27686285 TI - CTHRC1 promotes angiogenesis by recruiting Tie2-expressing monocytes to pancreatic tumors. AB - CTHRC1 (collagen triple-helix repeat-containing 1), a protein secreted during the tissue-repair process, is highly expressed in several malignant tumors, including pancreatic cancer. We recently showed that CTHRC1 has an important role in the progression and metastasis of pancreatic cancer. Although CTHRC1 secretion affects tumor cells, how it promotes tumorigenesis in the context of the microenvironment is largely unknown. Here we identified a novel role of CTHRC1 as a potent endothelial activator that promotes angiogenesis by recruiting bone marrow-derived cells to the tumor microenvironment during tumorigenesis. Recombinant CTHRC1 (rCTHRC1) enhanced endothelial cell (EC) proliferation, migration and capillary-like tube formation, which was consistent with the observed increases in neovascularization in vivo. Moreover, rCTHRC1 upregulated angiopoietin-2 (Ang-2), a Tie2 receptor ligand, through ERK-dependent activation of AP-1 in ECs, resulting in recruitment of Tie2-expressing monocytes (TEMs) to CTHRC1-overexpressing tumor tissues. Treatment with a CTHRC1-neutralizing antibody-abrogated Ang-2 expression in the ECs in vitro. Moreover, administration of a CTHRC1-neutralizing antibody to a xenograft mouse model reduced the tumor burden and infiltration of TEMs in the tumor tissues, indicating that blocking the CTHRC1/Ang-2/TEM axis during angiogenesis inhibits tumorigenesis. Collectively, our findings support the hypothesis that CTHRC1 induction of the Ang-2/Tie2 axis mediates the recruitment of TEMs, which are important for tumorigenesis and can be targeted to achieve effective antitumor responses in pancreatic cancers. PMID- 27686286 TI - Adsorbate-induced lifting of substrate relaxation is a general mechanism governing titania surface chemistry. AB - Under ambient conditions, almost all metals are coated by an oxide. These coatings, the result of a chemical reaction, are not passive. Many of them bind, activate and modify adsorbed molecules, processes that are exploited, for example, in heterogeneous catalysis and photochemistry. Here we report an effect of general importance that governs the bonding, structure formation and dissociation of molecules on oxidic substrates. For a specific example, methanol adsorbed on the rutile TiO2(110) single crystal surface, we demonstrate by using a combination of experimental and theoretical techniques that strongly bonding adsorbates can lift surface relaxations beyond their adsorption site, which leads to a significant substrate-mediated interaction between adsorbates. The result is a complex superstructure consisting of pairs of methanol molecules and unoccupied adsorption sites. Infrared spectroscopy reveals that the paired methanol molecules remain intact and do not deprotonate on the defect-free terraces of the rutile TiO2(110) surface. PMID- 27686287 TI - Splenorenal shunt via magnetic compression technique: a feasibility study in canine and cadaver. AB - INTRODUCTION: The concept of magnetic compression technique (MCT) has been accepted by surgeons to solve a variety of surgical problems. In this study, we attempted to explore the feasibility of a splenorenal shunt using MCT in canine and cadaver. MATERIAL AND METHODS: The diameters of the splenic vein (SV), the left renal vein (LRV), and the vertical interval between them, were measured in computer tomography (CT) images obtained from 30 patients with portal hypertension and in 20 adult cadavers. The magnetic devices used for the splenorenal shunt were then manufactured based on the anatomic parameters measured above. The observation of the anatomical structure showed there were no special structural tissues or any important organs between SV and LRV. Then the magnetic compression splenorenal shunt procedure was performed in three dogs and five cadavers. Seven days later, the necrotic tissue between the two magnets was shed and the magnets were removed with the anchor wire. RESULTS: The feasibility of splenorenal shunt via MCT was successfully shown in both canine and cadaver, thus providing a theoretical support for future clinical application.

PMID- 27686290 TI - Perceptions of house officers working in hospitals of Lahore about joining the field of anaesthesiology as a career. AB - OBJECTIVE: To determine the perceptions of house officers working in hospitals about joining anaesthesiology as a career. METHODS: This quantitative, descriptive questionnaire-based study was carried out from September 2014 to February 2015 in 26 teaching hospitals of Lahore, Pakistan, and comprised house officers. Those with at least three months of working experience in anaesthesiology were included. They were approached in their respective departments and a validated self-reporting questionnaire was delivered to them and received back by hand. SPSS 16 was used for data analysis. RESULTS: Of the 73 house officers approached, 53(72.6%) responded; 35(66%) men and 18(33%) women. Overall, 25(47.16%) respondents refused to join anaesthesiology as a career and 27(50.94%) included it in their first three career choices. Moreover, 25(47.16%) cited minimal interaction with patient as a reason for not taking anaesthesia as a career choice; 29(56.6%) of the respondents believed an anaesthetist had no or little role in surgery. Change in attitude about anaesthesiology as a specialty after having an anaesthesia rotation was mentioned by 26(49.05%) respondents. CONCLUSIONS: House officers had reservations about joining anaesthesiology as a career. The findings are suggestive of a positive effect of anaesthesiology house job on house officers attitude about the specialty. PMID- 27686291 TI - Perception of educational environment: Does it impact academic performance of medical students? AB - OBJECTIVE: To compare environmental perception as measured by the Dundee Ready Educational Environment Measure of students with high and low academic performance. METHODS: This cross-sectional analytical study was carried out at the Gujranwala Medical College, Gujranwala, Pakistan, and comprised medical students. Dundee Ready Educational Environment Measure questionnaire with 50 items was used to determine students' perception of the institutional environment. Academic performance was based on mean percentage of marks obtained in all professional examinations. High achievers with 70% or more marks were compared with low achievers with <70% marks for Dundee Ready Educational Environment Measure scores using unpaired Student's t-test. RESULTS: Of the 180 students, 153(85%) were included. Of them, 35(22.87%) were boys and 118(77.12%) girls. The overall mean Dundee Ready Educational Environment Measure score was 116.13+/-18.24. As for the subscales, the mean score for 'perceptions of learning' was 27.97+/-6.0, 25.76+/-4.6 for 'perceptions of teachers', 18.67+/ 4.05 for 'academic self-perceptions', 27.76+/-6.03 for perceptions of atmosphere and 15.97+/-3.0 for social self-perceptions. The mean dream score was 108.51+/ 17.54 among boys and 118.39+/-17.90 among girls. The mean score for perception of having successful learning strategies was 1.66+/-0.9and 2.18+/-0.9 among low and high achievers (p>0.05) and 1.71+/-0.98 and 2.18+/-1.1 for ability to memorise all that was needed (p>0.05). CONCLUSIONS: Environmental perception of the institution was more positive than negative and better performance in examinations was associated with better academic self-perception and social self perception in students. PMID- 27686292 TI - Serum vitamin D levels and gene polymorphisms (Fok1 and Apa1) in children with type I diabetes and healthy controls. AB - OBJECTIVE: To compare the pattern of Vitamin D receptor (VDR) polymorphisms (Apa I and Fok I) in Type I Diabetes mellitus (T1DM) as cases vs healthy population as control and to investigate the association of VDR polymorphism with vitamin D levels in cases and controls. METHODS: The hypothesis of the study was "VDR gene polymorphisms (Fok 1 and Apa 1) and vitamin D levels are associated with the T1DM". The case-control study was carried out on 44 cases and 44 controls. Clinically diagnosed unrelated cases were recruited from the Diabetic Clinic of Jinnah Hospital, Lahore during Aug. 2012 to Jan 2013. Unrelated controls with normal glucose levels and no first-degree family history of T1DM were selected by convenient sampling. Vitamin D levels of both cases and controls were measured using Enzyme Linked Immunosorbant Assay (ELISA). Genotyping was performed by Restriction Fragment Length Polymorphism (RFLP)-PCR method and the data were analyzed statistically with IBM-SPSS 21. RESULTS: Our results demonstrated suboptimal vitamin D levels in whole of our sample population, whether control or cases (p = 0.529). There was no statistically significant difference in 25 Hydroxyvitamin D3 levels between cases (11.351 +/- 5.92) and controls (12.335 +/- 6.64). VDR polymorphism was not associated with susceptibility to T1DM in our sample population. Similarly, no association between VDR polymorphism and vitamin D levels was observed i.e. FokI p=0.507 and p=0.543 and ApaI p=0.986 and p=0.307 for cases and controls respectively. CONCLUSIONS: There is an overall deficiency of Vitamin D levels in cases and control subjects while SNPs association studies suggested that in our sample population there was no association of VDR gene polymorphisms Fok I and Apa I with TIDM. PMID- 27686293 TI - Neck circumference: A supplemental tool for the diagnosis of metabolic syndrome. AB - OBJECTIVE: To explore the usefulness of neck circumference as a supplemental tool for diagnosing metabolic syndrome while identifying its cut-off values. METHODS: This case-control study was conducted at Dr. Essa's Laboratory and Diagnostic Centre, Karachi, from December 2014 to April 2015, and comprised subjects with and without metabolic syndrome aged between 35 and 65 years regardless of their diabetic status. Evaluation was done for metabolic syndrome by measuring anthropometric, clinical and biochemical parameters according to the criteria proposed by the International Diabetes Federation. Variables in both cases and controls were correlated with neck circumference and its cut-off values were determined for diagnosing metabolic syndrome. SPSS 20 was used for statistical analysis. RESULTS: Of the 215 subjects enrolled, 164(76.28%) were selected. Of them, 83(50.61%) were cases and 81(49.39%) were controls. Moreover, 90(55%) of them were men and 74(45%) were women. The overall mean age was 51.15+/-10.36 years (range: 35 to 65 years).The mean neck circumference was 36.13+/-2.14 cm and 31.59+/-1.18 cm in normal-weight men and women, respectively, compared with 40.0+/-2.13 cm and 35.75 +/- 2.74 cm among obese men and women. The neck circumference correlated best with waist circumference in men (p=0.001) and with body surface area in women (p=0.001). The area under the curve of neck circumference for metabolic syndrome was 0.760 for men (p<0.001) and 0.631 for women (p<0.05). Optimal neck circumference cut-off points to determine metabolic syndrome were >38 cm for men and >34 cm for women. The odds ratio for metabolic syndrome was 12.44 (95% confidence interval: 4.13-37.41) among male cases and controls compared to 3.34 (1.26-8.80) among women. CONCLUSIONS: Neck circumference strongly correlated with adiposity indices and had a definite cut off point. It can therefore be used as a useful adjunct for clinical screening of metabolic syndrome. PMID- 27686294 TI - The effect of ethanol vapour exposure on atrial and ventricular walls of chick embryos. AB - OBJECTIVE: To study the effects of ethanol vapour exposure on atrial and ventricular walls of heart in chick embryo. METHODS: The study design was experimental, conducted at Islamabad Centre of College of Physicians and Surgeons, Pakistan. One hundred and eighty chicken eggs were divided into two groups, experimental and control, of 90 eggs each. Each group was subdivided into three subgroups of 30 eggs each based on the day of sacrifice. Experimental group was exposed to ethanol vapours and then compared with age matched controls. RESULTS: The thickness of atrial and ventricular walls along with lengths of valvular cusps increased in hearts of day 7 and day 10 chick embryos in experimental group. There was thinning of walls and decreased length of valvular cusps in hearts of experimental chicks on hatching as compared to age matched controls. CONCLUSIONS: Ethanol vapour exposure during development causes cardiac and septal wall thickening during initial days of development followed by cardiac and septal wall thinning which is a classical picture of alcohol induced cardiomyopathies.

AB - OBJECTIVE: To identify major dietary patterns and examine their association with anthropometric, lifestyle and socio-economic factors among women belonging to different communities living in Karachi. METHODS: This cross-sectional study was conducted in Karachi from June 2014 to August 2015, and comprised women of Aga Khani, Dawoodi Bohra and Memon communities. Dietary data was collected through a 108-item food frequency questionnaire and dietary patterns were derived by factor analysis. Three dietary patterns were extracted: processed, mixed and traditional. SPSS 20 was used for data analysis. RESULTS: Of the 322 participants, 108(33.54%) belonged to the Aga Khani community, and 107(33.23%) each to Dawoodi Bohra and Memon communities. Moreover, 58(53.7%), 39(36.4%) and 25(23.4%) in the three groups, respectively, had a university degree. Besides, 44(40.7%) women belonging to the Aga Khani community were married, compared to 53(49.5%) and 37(34.6%) in Dawoodi Bohra and Memon communities. The mean factor loading for mixed food pattern was 0.24 among women of the Aga Khani community, whereas respective values for Dawoodi Bohra and Memon communities were 0.005 and 0.25. The mean factor loading for traditional pattern was 0.77 in the Dawoodi Bohra community, in contrast to -0.24 and -0.52 among women belonging to Memon and Aga Khan communities. Processed food pattern was negatively associated with age in the Aga Khani community (p<0.001) and Dawoodi Bohra community (p=0.010). Mixed food pattern was positively associated with family size in the Aga Khani community (p=0.007), with watching television for 1-3 hours (p=0.007) and higher family income in the Dawoodi Bohra community (p=0.009). Traditional food pattern depicted a positive association for watching television >1-3 hours/day (p=0.028) and total calorie consumption/day (p=0.008) in Dawoodi Bohra community. A negative trend was noted for watching television (1-3 hours/day p=0.020; >3hours/day p=0.004) and physical inactivity (p=0.039) in the Memon community. CONCLUSIONS: Lifestyle and socio-economic variables were found to be associated with dietary patterns in all communities.

METHODS: This prospective, observational study was conducted at 1 Mountain Medical Battalion, Bagh, Azad Kashmir, from May 2012 to April 2015, and comprised adult type 2 diabetics. Patients already on lipid lowering agents, hypothyroidism, nephrotic syndrome, unwilling patients and those who had serum triglycerides>4.5mmol/l were excluded. Blood pressure was measured twice in sitting position. Amongst hypertensive patients, blood pressure <140/90mmHg reflected good control. Serum total cholesterol, triglyceride and high-density lipoproteins were measured using enzymatic calorimetric method. Friedewald equation was used to calculate low-density lipoprotein levels.Subjects were divided into three groups: those without hypertension; those with hypertension but good blood pressure control; and hypertensives with poor blood pressure control. SPSS 20 was used for data analysis. RESULTS: Of the 322 patients, 129(40.06%) were women and 193(59.94%) were men. The overall mean age was 51.42+/-10.93 years. Hypertension was seen in 144(44.72%) patients. Blood pressure was well controlled in 46(31.94%) hypertensive patients. Among patients without hypertension and those with good or poorly controlled blood pressure, the mean values for serum total cholesterol were 181.08+/- 32.05, 186.87+/- 39.00, 185.33+/- 35.55 mg/dl, triglycerides were 172.57+/-80.53, 187.61+/-81.42, 183.19+/-74.34 mg/dl, high-density lipoproteins were 40.54+/-12.36, 37.06+/-8.80, 40.15+/-12.35 mg/dl and low-density lipoproteins were 105.79+/-29.73, 110.81+/ 31.66, 106.56+/-35.16 mg/dl. The number of patients with abnormalities of total cholesterol was 44(26.83%), 13(28.26%), 33(29.46%), triglycerides was 83(50.61%), 30(65.22%), 66(58.93%), high-density lipoproteins was 119(72.56%), 39(84.78%), 93(83.04%) and low-density lipoproteins was 90(54.88%), 29(63.04%) and 59(52.68%), respectively.

PMID- 27686302 TI - Age-related cataract and its types in patients with and without type 2 diabetes mellitus: A Hospital-based comparative study. AB - OBJECTIVE: To determine the frequency and types of age-related cataract in type 2 diabetic patients compared to non-diabetics. METHODS: This comparative, cross sectional study was carried out at Al-Ibrahim Eye Hospital, Karachi, from July 2014 to June 2015, and comprised both diabetics and non-diabetics. All patients were selected from the out-patient department and had their full ocular examination done, including retinal screening of diabetic patients with non mydriatic fundus camera. The criterion for diagnosis of cataract was sufficiently advanced lens opacity that caused impaired vision/un-gradable images. Cataract was classified on a morphological basis into cortical, nuclear, posterior sub capsular and mixed types. RESULTS: Of the 49,384 patients, 4,556(9.2%) were diabetics and 44,828(90.8%) were non-diabetics. Among the diabetics, cataract was found in 1,956(42.9%) compared to 7,050(15.7%) in non-diabetics. Adjusted odds ratio (95% confidence interval) between the two groups was 4.40 (range: 4.11 4.71) (p<0.001). Male-to-female adjusted odds ratio (95% confidence interval) was 2.05 (range: 1.95-2.15) (p<0.001). Nuclear sclerosis was the commonest type in 2,123(46.6%) cataract cases in diabetics whereas posterior sub-capsular cataract was the commonest type in 14,480(32.3%) cases among the non-diabetics. CONCLUSIONS: Cataract was four times more common in diabetics and twice more frequent in men. Nuclear sclerosis was the commonest type of cataract in diabetic patients.

PMID- 27686304 TI - Frequency of post-stroke dysphagia in Pakistan: a hospital based study. AB - OBJECTIVE: Purpose of the study is to determine the frequency of dysphagia after stroke and to see the factors associated with it. METHODS: Cross Sectional study design was used by including individuals pre-diagnosed as stroke on the basis of CT scan or MRI findings. Study was conducted in three hospitals of Lahore within six months. Sample size of 150 patients of any age and both gender was taken by using convenient sampling technique. To assess the conscious level, Glasgow coma scale was administered and those who scored mild or moderate on GCS were included in the study. Modified Massey Bedside Swallow Screener was used to screen out the patients for dysphagia. SPSS-19 was used for the statistical analysis. RESULTS: In the sample of 150 individuals with stroke 53% of patients had dysphagia. Females were 38% while males were 62%. Individuals who were older were more likely to have dysphagia. Among dysphagic individuals 65% had ischemic stroke while 35% were with haemorrhagic. There were 87% of dysphagic individuals who presented with history of smoking and 13% were without any. These factors demonstrate significant relationship by showing p-value <0.05. While no significant difference was seen between levels of alertness and risk of dyspagia by showing p-value 0.2. CONCLUSIONS: Dysphagia after stroke occurs frequently that should be actively assessed and factors like type of stroke and history of smoking are significantly related to this condition. PMID- 27686305 TI - Pioglitazone improves serum lipid profile in diet induced hyperlipidaemic non diabetic rats. AB - OBJECTIVE: To evaluate the anti-dyslipidaemic effects of pioglitazone in diet induced non-diabetic hyperlipidaemic rats and to compare them with gemfibrozil. METHODS: This comparative animal study was conducted at the Postgraduate Medical Institute, Lahore, Pakistan, from July to September 2011, and comprised Sprague Dawley albino rats divided into three equal groups. Initially all three groups were given high-lipid diet containing cholesterol 1.5g, coconut oil 8ml and sodium cholate 1.0g per 100g of rat chow to induce hyperlipidaemia. From 4th to 8th week, Group A (control) was given 0.5ml of distilled water, Group B was given pioglitazone 10mg/kg body weight, and Group C was given gemfibrozil 10mg/kg body weight as single morning dose by oral route for a period of 04 weeks in addition to hyperlipidaemic diet. Serum lipid levels were estimated at zero, 4th and 8th week. Blood sugar level was estimated at 4th week to exclude diabetic rats.SPSS 17 was used for data analysis. RESULTS: Of the 27 rats, each group had 9(33.33%) rats. At the start of the study, the mean weight was 254.44+/-14.67g in Group A, 255.11+/-14.66g in Group B and 252.22+/-14.18g in Group C. It was 352.22+/ 16.79g, 332.22+/-17.19 and 328.11+/- 12.92 at the 8th week. The mean total cholesterol at 0 week was 71.4+/-4.88 mg/dl in Group A, 71.9+/-7.03 in Group B and 73.4+/-5.27 in Group C. At the 8th week, the values were 161.8+/-9.2 mg/dl, 100.8+/-7.0 and 95.0+/-6.6. The mean low-density lipoproteincholesterol levels in the respective groups were 30.2+/-4.9mg/dl, 32.2+/-7.0 and 33.6+/-6.0 at 0 week; 77.8+/-8.4, 85.1+/- 15.3 and 86.9+/- 6.3 at the 4th week and 113.9+/- 10.1, 60.4+/- 9.2 (p< 0.001) and 54.8+/- 6.6 (p< 0.001) at the 8th week.The mean serum high-density lipoprotein cholesterol at the 8th week was 11.4+/- 1.7 mg/dl, 19.7+/- 2.4 (p< 0.001) and 19.2+/- 2.5 (p< 0.001) in the three groups, respectively. CONCLUSIONS: Treatment with pioglitazone improved serum lipid profile of non-diabetic hyperlipidaemic rats equivalent to that of gemfibrozil. PMID- 27686306 TI - Antimicrobial susceptibility of bacterial and fungal infections among infected diabetic patients. AB - Objective: To determine the antimicrobial susceptibility of the most common bacterial and fungal infections among infected diabetic patients. Methods: This study was conducted at the Umm Al-Qura University, Makkah, Saudi Arabia, from June 2011 to June 2012, and comprised specimens collected from diabetics. Antibiotic susceptibility test using disc diffusion method was performed for bacterial isolates, and antifungal susceptibility test using colorimetric method for candida isolates. Results: Of the 138 specimens, antibacterial susceptibility test was performed for 129(93.5%) bacterial isolates while antifungal resistance test was performed for 9(6.5%) candida isolates. Of the bacterial isolates, 27(20.9%) were escherichia coli, 26(20.1%) staphylococcus aureus and 15(11.6%) were pseudomonas aeruginosa isolates. All Escherichia coli and staphylococcus aureus were susceptible to amikacin and vancomycin (100% each). Moreover, all candida species were susceptible to amphotericin B, econazole, fluconazole, ketoconazole and nystatin (100% each). CONCLUSIONS: The most effective antibiotics for bacterial infections among diabetic patients were vancomycin for gram-positive bacteria, amikacin for gram-negative bacteria and for bacteria isolated from diabetic patients with foot infections.

AB - OBJECTIVE: To determine friend leukaemia integration 1 transcription factor protein expression in cases of Ewing sarcoma. METHODS: This retrospective, descriptive study was conducted at the Armed Forces Institute of Pathology, Rawalpindi, Pakistan, and comprised data of diagnosed cases of Ewing sarcoma related to the period from February 2013 to December 2014. Clinico-pathological features, including patient age, gender and site of biopsy were studied. Positivity of immunohistochemical markers such as cluster of differentiation 99(membranous staining) and Friend leukaemia integration 1 transcription factor (nuclear staining) were noted. SPSS17 was used for data analysis. RESULTS: Of the 50 Ewing sarcoma cases, 26(52%) related to women and 24(48%) to men. The overall mean age was 17+11.53 years (range: 3 to 42 years). Moreover, 30(60%) patients had presented with bone swelling or growth whereas 20(40%) had presented with soft tissue swelling. The site of presentation was upper extremities in 16(32%) patients, lower extremities in 14(28%), maxilla in 7(14%), chest wall in 6(12%), paraspinal region in 4(8%), scalp in 2(4%) and retroperitoneum in 1(2%). Membranous positivity for cluster of differentiation 99 was seen in 48(98%) cases. Nuclear positivity for Friend leukaemia integration 1 transcription factor was seen in 39(78%) cases. CONCLUSIONS: Friend leukaemia integration 1 transcription factor was found to be a useful marker in diagnosing Ewing sarcoma/peripheral primitive neuroectodermal tumour. However, its positivity was more dependable when it was used in combination with other markers such as cluster of differentiation 99. PMID- 27686308 TI - Serum YKL-40 and MDA levels in Behcet disease. AB - OBJECTIVE: To measure plasma levels of chitinase-3-like 1 protein and its association with malondialdehyde in Behcet's disease patients. METHODS: The case control study was conducted at Faculty of Medicine, Ataturk University Erzurum, Turkey, from October 2012 to March 2014, and comprised patients with Behcet's disease and healthy subjects. The patients were divided into two groups, as active and inactive, based on the classification of phases of activity in Behcet's disease. Differences between groups were analysed. SPSS 20 was used for data analysis. RESULTS: Of the 79 participants, 51(64.56%) were patients and 28(35.44%) were controls. The mean age of the first group was 29.45+/-7.82 years and the second group was 32.21+/-9.61 years. Among patients, 37(72.55%) were categorised as "active" and 14(27.45%) as "inactive". Median serum Chitinase-3 like 1 protein and malondialdehyde levels were 37.57 ng/mL (interquartilerange: 13.7-293.0 ng/mL) in patients and 26.25 ng/mL (interquartile range: 17.0-44.7 ng/mL) in controls. There was no significant correlation between Chitinase-3-like 1 protein and malondialdehyde (p>0.05). CONCLUSIONS: Chitinase-3-like 1 protein might be associated with Behcet's disease. Elevated malondialdehyde levels were not only the cause of inflammation but also indicator of oxidative stress in Behcet's disease. PMID- 27686309 TI - Temperature on admission among cases of neonatal sepsis and its association with mortality. AB - OBJECTIVE: To ascertain the prevalence of hyperthermia and different categories of hypothermia among the cases of probable and culture-proven neonatal sepsis, and to evaluate association of mortality rate with axillary temperature at admission. METHODS: This analytical study was conducted at Fazl-e-Omar Hospital, Rabwah, Pakistan, from January to December 2013, and comprised all cases of culture-proven and probable neonatal sepsis admitted in the neonatal intensive care unit of the hospital. Using World Health Organisation classification, cases were categorised according to their temperature on admission, and outcome was recorded. SPSS 20 was used for data analysis. RESULTS: Of the 374 patients, 47(12.6%) died. Besides, 217(58%) cases had normal temperature, 49(13.1%) had hyperthermia, 50(13.4%) had mild hypothermia, and 58(15.5%) had moderate hypothermia. Mortality rate was high among cases with mild and moderate hypothermia i.e. 15(32.6%) and 15(33%), compared with the mortality rate in cases with normal temperature i.e. 12(6.1%). Mortality rate among cases with hyperthermia was 5(11.6%). In early onset cases, 33(16.2%) had mild and 45(22.1%) had moderate hypothermia. In late onset cases, 37(21.8%) had hyperthermia. CONCLUSIONS: Most cases with neonatal sepsis had normal temperature. Mild and moderate hypothermia were found to be associated with higher mortality rate. PMID- 27686310 TI - Research productivity of Gulf Cooperation Council (GCC) countries in science and social sciences. AB - OBJECTIVE: To investigate the research progress of Gulf Cooperation Council countries in science and social sciences. METHODS: This study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia, from June 2014 to February 2015.All research documents related to the 1996-2013 period having an affiliation with Gulf Cooperation Council countries, including Saudi Arabia, the United Arab Emirates, Kuwait, Qatar, Bahrain and Oman, were tracked. The main source for data-gathering was World Association of Universities, Sci-mago Journal and Country ranking and Web of Science Institute of Scientific Information (ISI) Thomson Reuters. RESULTS: Of the 544 institutions produced research papers, 141(25.92%) were universities or degree-awarding institutes, 372(68.38%) were research institutes and 31(5.7%) were Institute of Scientific Information-indexed scientific journals. The number of degree awarding institutes were 68(48.23%) in Saudi Arabia, 33(23.4%) in the United Arab Emirates and 12(8.51%) in Qatar. The total number of publications contributed by the region was 133638 (Mean +/- SD: 22273 +/- 26302.20); citable documents 127739 (Mean +/- SD: 21289.83 +/-25241.22); self-citations 105,716 (Mean +/- SD: 17619.33 +/- 23328.44); total citations 756141 (Mean +/- SD: 126023.5 +/- 143260.95) and citations per documents 33.22 (Mean +/- SD: 5.53 +/- 1.09).The overall and mean Hirschindex was 513and 85.5+/- 35.39. CONCLUSIONS: Among Gulf Cooperation Council countries, Saudi Arabia was the most productive country producing adequate number of research publications, citations and holding the highest Hirsch index value. PMID- 27686311 TI - Proton pump inhibitors use; beware of side-effects. AB - Proton pump inhibitors are most widely prescribed medicines all over the world. Since their introduction in pharmacy, life of millions of people has changed completely. Their ability to inhibit acid secretion in stomach has changed the natural history of many once-dreaded conditions like peptic ulcer and gastroesophageal reflux disease. Operation like gastrectomy and partial gastrectomy are carried out very rarely. These medicines are considered very cost effective, have excellent safety profile, and provide prompt symptomatic relief. However, they are not without side effects, and several warnings have been issued by the Food and Drug Agency of the United States about the risk of hypomagnesaemia, possibility of increased fracture risk, and reduction in efficacy of clopidogrel by concomitant use of proton pump inhibitors. But despite all these warnings, their use is still on the rise. This Review was planned to highlight side effects and drug interactions so that a practising physician may keep the rare but potentially devastating effects in mind while prescribing the pumps. PMID- 27686312 TI - Domestic violence in consanguineous marriages - findings from Pakistan Demographic and Health Survey 2012-13. AB - Domestic violence is a pandemic and estimated to affect one in three women globally, in their lifetime. Marriages within blood relations in Pakistan are common. In this study a secondary analysis of Pakistan Demographic and Health Survey 2012-13 was done to study the prevalence and profile of domestic violence in the context of consanguineous marriages in Pakistan. Almost 65% of women had some kind of blood relationship with their husbands. Women having a blood relationship with husbands were more likely to report having ever been subjected to marital control behaviours, emotional and physical violence by their husbands, compared to ones without such relationship. However, these associations fail to reach statistical significance; underscoring the ubiquitous nature of marital control and violence. More effective public health education campaigns for just and equal treatment of wives by their husbands to speedily curb the scourge of domestic violence in the country are needed. PMID- 27686313 TI - Bilateral optic neuropathy, acral gangrene and visceral ischaemia as a rare presentation of calciphylaxis: A case report. AB - We report a case with calciphylaxis very rarely presenting with bilateral optic neuropathy, acral gangrene and visceral ischaemia. Bilateral papilloedaema was found in a 43 year-old female with chronic renal failure. Acral dry gangrene was observed. Pathological examination of her amputated thumb revealed calcification, thrombi, obstructive endovascular fibrotic areas in the walls of arteries. She was diagnosed with calciphylaxis. Bilateral optic neuropathy was defined secondary to calciphylaxis. Abdominal computerized tomography revealed prominent calcifications in mesenteric, spleen and renal arteries. She died eight months after the diagnosis. Calciphylaxis should be considered in the differential diagnosis of the optic neuropathy. PMID- 27686314 TI - Catamenial pneumothorax: A case report. AB - Catamenial pneumothorax (CP) is a rare and complex clinical condition caused by endometrial tissues, commonly found in reproductive women (age 15-49 years).Its diagnosis is often delayed or overlooked by clinicians, which may result in recurrent hospitalizations and other complications. A case of Catamenial pneumothorax is presented of a 38-year-old young married woman, admitted to hospital with signs and symptoms including chest pain and shortness of breath that started with her menstrual period. Right pneumothorax was observed in the Chest x-ray. Patient underwent Video-assisted thoracoscopic surgery (VATS). Patient was kept under observation, and was discharged when stable with no pain.Catamenial pneumothorax is still considered to be a mysterious disease and difficult to diagnose. Surgery is the best treatment. PMID- 27686315 TI - Management of Cyclops Syndrome: A case report. AB - Anterior Cruciate ligament (ACL) is a typical athletic injury. One of the most frequent complication after ACL reconstruction is reduced range of motion (ROM) due to the impingement on the inter-condylar notch of a fibrous tissue mass, defined as Cyclops Syndrome. We report the case of a 25 years old male, who underwent reconstruction of ACL with Gracilis-semitendinosus (GR-ST) tendons with delayed onset of loss of knee extension seven years after ACL reconstruction. Clinical and magnetic resonance image (MRI) findings were consistent with Cyclops syndrome. The patient underwent arthroscopy in May 2015, which revealed a fixed fibrous nodule impinging on the inter-condylar notch in extension that was treated by mechanical shaving, radiofrequency ablation remodeling inter-condylar notch and releasing of the ACL transplant. After surgery our patient returned to his routine activities after 5 days and started running about 10 days later, without anterior knee pain and without deficit of hyperextension. PMID- 27686316 TI - Alveoler process fracture in mandibular immature permanent incisors region. AB - The presented case evaluates the treatment of an alveolar fracture associated with mandibular immature lower permanent incisors. An 8-year-old girl was referred to our clinic 3 hours after the trauma. The clinical and radiographic examination of the alveoler bone showed a fracture, along with the mandibular fracture and significant segment mobility and dislocation of several immature mandibular permanent incisors. These were moving together to the lingual side because of the direct trauma associated with falling from the school wall. After the application of the buccal and lingual infiltration of local anaesthesia, the dislodged bone including the lower permanent incisors, were carefully repositioned. The teeth were splinted using semi-rigid arch bars with orthodontic brackets keeping the teeth between primary molars.The splints were removed one month later and no abnormality was observed in the immature permanent incisors. After 24 months follow up, the mandibular permanent incisors were observed to have the apical closure. Treatment of alveolar fractures in growing children with immature teeth may provide beneficial healing pattern with careful semi-rigid splinting and follow up procedures. PMID- 27686317 TI - Extra pancreatic solid pseudopapillary tumour in a young male. AB - Solid pseudo-papillary tumour of pancreas is a rare neoplasm having a low malignant potential. It mostly affects young adolescent females. We report an unusual case of an 18 year old male with a mass in the mesocolon which was reported as solid pseudo-papillary tumour of pancreas. This case is unusual by virtue of extra pancreatic location and male gender of the patient. PMID- 27686318 TI - Henoch-Schonlein purpura without typical lesions, presenting with gastrointestinal manifestations and kidney involvement following influenza - A case report. AB - We report a case of Henoch-Schonlein purpura (HSP) presenting without typical skin lesion; atypical symptoms initially appeared following influenza infection. A 4-year-old girl with influenza presented with epigastric pain and vomiting. On physical examination, there was epigastric tenderness, but no other signs, such as skin rash. On the second day, she vomited blood 10 times. Ultrasonography indicated focal bowel wall thickening in the right upper quadrant. Esophagogastroduodenoscopy showed oedematous and purpuric mucosa in the gastric pylorus and duodenum. Steroid therapy was initiated, and symptoms improved, but microscopic haematuria persisted. Even in the absence of typical purpura, if any gastrointestinal symptoms are observed and HSP is suspected, aggressive diagnostic tools must be considered, including ultrasonography or endoscopy. With only a few reported cases of HSP associated with influenza infection, this is the first reported case with gastrointestinal involvement and renal impairment, but without typical skin lesions. PMID- 27686319 TI - Choice of first injectable therapy in type 2 diabetes. AB - A variety of injectable therapies are now available for use in patients of type 2 diabetes mellitus, when metformin alone proves inadequate. These injectable therapies include basal insulins, glucagon-like peptide 1 receptor agonists (GLP1RA), co-formulations of basal insulin with GLP1RA, and premixed or co formulated dual action insulins. This article helps choose appropriate first injectable therapy in a rational manner, and achieve glycaemic control in an efficient way. The discussion utilizes the pharmacokinetic and pharmacodynamic properties of various injectable drugs to match them with various clinical situations. It highlights a gluco-phenotypic approach, utilizing readily available anthropometric measurements, glycaemic patterns, and other bio psychosocial parameters, to create a simple model which facilitates correct choice of first injectable therapy in type 2 diabetes. PMID- 27686320 TI - Diabetes and travel. AB - This article encapsulates pragmatic advice that is necessary to ensure safe travel for people with diabetes.

PMID- 27686322 TI - Prevalence of Blood Lead Levels (BLLs) in children visiting tertiary care hospitals of Peshawar from February to April 2015: A pilot study. AB - OBJECTIVE: To determine blood lead level in young children visiting tertiary care hospitals. METHODS: This cross-sectional study was conducted from February to April 2015 at Khyber Teaching Hospital, Kuwait Teaching Hospital and Siffat Ghayoor Memorial Children's Hospital, Peshawar, Pakistan, and comprised children aged1-10 years. Purposive sampling technique (non-probability) was used. SPSS 17 was used for data analysis. Charts were made in Microsoft Excel 2007. RESULTS: Of the 100 children in the study, 79(79%) had lead present in their blood, while 21(21%) had no traces whatsoever. Of those who had lead in their blood, 5(6%) showed blood lead level of above 1 mg/dL. The overall mean blood lead level was 0.344+/- 0.05 mg/dL. There was significance association between lead level and the residential areas of participants (p<0.05). CONCLUSIONS: Lead was found in the blood of children aged 1-10 years and was significantly related to the place of residence. Age and gender had no relation with blood lead levels. PMID- 27686323 TI - Observation of orbital two-channel Kondo effect in a ferromagnetic L10-MnGa film. AB - The experimental existence and stability of the fixed point of the two-channel Kondo (2CK) effect displaying exotic non-Fermi liquid physics have been buried in persistent confusion despite the intensive theoretical and experimental efforts in past three decades. Here we report an experimental realization of the two level system resonant scattering-induced orbital 2CK effect in a ferromagnetic L10-MnGa film, which is signified by a magnetic field-independent resistivity upturn that has a logarithmic and a square-root temperature dependence beyond and below the Kondo temperature of ~14.5 K, respectively. Our results not only evidence the robust existence of orbital 2CK effect even in the presence of strong magnetic fields and long-range ferromagnetic ordering, but also extend the scope of 2CK host materials from nonmagnetic nanoscale point contacts to diffusive conductors of disordered alloys. PMID- 27686324 TI - Ultraviolet-B Radiation (UV-B) Relieves Chilling-Light-Induced PSI Photoinhibition And Accelerates The Recovery Of CO2 Assimilation In Cucumber (Cucumis sativus L.) Leaves. AB - Ultraviolet-B radiation (UV-B) is generally considered to negatively impact the photosynthetic apparatus and plant growth. UV-B damages PSII but does not directly influence PSI. However, PSI and PSII successively drive photosynthetic electron transfer, therefore, the interaction between these systems is unavoidable. So we speculated that UV-B could indirectly affect PSI under chilling-light conditions. To test this hypothesis, the cucumber leaves were illuminated by UV-B prior or during the chilling-light treatment, and the leaves were then transferred to 25 degrees C and low-light conditions for recovery. The results showed that UV-B decreased the electron transfer to PSI by inactivating the oxygen-evolving complex (OEC), thereby protecting PSI from chilling-light induced photoinhibition. This effect advantages the recoveries of PSI and CO2 assimilation after chilling-light stress, therefore should minimize the yield loss caused by chilling-light stress. Because sunlight consists of both UV-B and visible light, we suggest that UV-B-induced OEC inactivation is critical for chilling-light-induced PSI photoinhibition in field. Moreover, additional UV-B irradiation is an effective strategy to relieve PSI photoinhibition and yield loss in protected cultivation during winter. This study also demonstrates that minimizing the photoinhibition of PSI rather than that of PSII is essential for the chilling-light tolerance of the plant photosynthetic apparatus. PMID- 27686325 TI - Nebivolol Ameliorates Cardiac NLRP3 Inflammasome Activation in a Juvenile Adolescent Animal Model of Diet-Induced Obesity. AB - NLRP3 is involved in obesity-induced cardiac remodeling and dysfunction. In this study, we evaluated whether the cardiac protective effects of nebivolol relied on attenuating NLRP3 activation in a juvenile-adolescent animal model of diet induced obesity. Weaning male Sprague-Dawley rats were fed with either a standard chow diet (ND) or a high-fat diet (HFD) for 8 weeks. The obese rats were subsequently subdivided into three groups: 1) HFD control group; 2) HFD with low dose nebivolol (5 mg/kg/d); 3) HFD with high-dose nebivolol (10 mg/kg/d). Treatment with nebivolol prevented HFD-induced obesity associated excess cardiac lipid accumulation as well as myocardial mitochondrial dysfunction. Nebivolol attenuated pro-inflammatory cytokines secretion and NLRP3 inflammasome activation in myocardium of obese rats. In parallel, nebivolol treatment of obese animals increased cardiac beta3-AR expression, reversing the reduction of endothelial nitric oxide synthase (eNOS). In vitro, nebivolol treatment of palmitate incubated H9C2 cells suppressed autophagy, restored mitochondrial biogenesis, leading to decreased mitochondrial reactive oxygen species (mtROS) generation, and suppressed NLRP3 inflammasome activation. Meanwhile the presence of shRNA against beta3-AR or against eNOS deteriorated the protective effects of nebivolol. These data suggest the beneficial effect of nebivolol on myocardial lipotoxicity contributing to inhibiting NLRP3 inflammasome activation possibly via improved mitochondrial dysfunction. PMID- 27686327 TI - How the BMA lost control of the junior doctors' dispute. PMID- 27686326 TI - Association of Microcirculation, Macrocirculation, and Severity of Illness in Septic Shock: A Prospective Observational Study to Identify Microcirculatory Targets Potentially Suitable for Guidance of Hemodynamic Therapy. AB - PURPOSE: Clinically unapparent microcirculatory impairment is common and has a negative impact on septic shock, but specific therapy is not established so far. This prospective observational study aimed at identifying candidate parameters for microcirculatory-guided hemodynamic therapy. ClinicalTrials.gov : NCT01530932. MATERIALS AND METHODS: Microcirculatory flow and postcapillary venous oxygen saturation were detected during vaso-occlusive testing (VOT) on days 1 (T0), 2 (T24), and 4 (T72) in 20 patients with septic shock at a surgical intensive care unit using a laser Doppler spectrophotometry system (O2C). RESULTS: Reperfusional maximal venous capillary oxygen saturation (SvcO2max) showed negative correlations with Simplified Acute Physiology Score II (SAPSII)/Sequential Organ Failure Assessment (SOFA) score, norepinephrine dosage, and lactate concentration and showed positive correlations with cardiac index (CI). At T24 and T72, SvcO2max was also inversely linked to fluid balance. With respect to any predictive value, SvcO2max and CI determined on day 1 (T0) were negatively correlated with SAPS II/SOFA on day 4 (T72). Moreover, SvcO2max measured on day 1 or day 2 was negatively correlated with cumulated fluid balance on day 4 ( r= -.472, P < .05 and r = -.829, P < .001). By contrast, CI neither on day 1 nor on day 2 was correlated with cumulated fluid balance on day 4 ( r = .343, P = .17 and r = -.365, P = .15). CONCLUSION: In patients with septic shock, microcirculatory reserve as assessed by SvcO2max following VOT was impaired and negatively correlated with severity of illness and fluid balance. In contrast to CI, SvcO2max determined on day 1 or day 2 was significantly negatively correlated with cumulative fluid balance on day 4. Therefore, early microcirculatory measurement of SvcO2max might be superior to CI in guidance of sepsis therapy to avoid fluid overload. This has to be addressed in future clinical studies. PMID- 27686328 TI - Value and usability of unpublished data sources for systematic reviews and network meta-analyses. AB - Peer-reviewed publications and conference proceedings are the mainstay of data sources for systematic reviews and network meta-analyses (NMA), but access to informative unpublished data is now becoming commonplace. To explore the usefulness of three types of 'grey' literature-clinical trials registries, clinical study reports and data from regulatory authorities-we conducted four case studies. The reporting of outcome data in peer-reviewed publications, the clinical trials registries and the clinical study reports for two clinical trials one in melanoma, one in juvenile idiopathic arthritis (JIA)-was examined. In addition, we assessed the value of including unpublished data from the European Medicines Agency (EMA) and US Food and Drug Administration (FDA) in evidence syntheses of hepatitis C virus (HCV) and chronic obstructive pulmonary disease (COPD), respectively. For the clinical trials in melanoma and JIA, we identified outcome parameters on ClinicalTrials.gov additional to those reported in the peer reviewed publications: subgroup data and additional efficacy end points/extended follow-up, respectively. The clinical study report also provided results for several subgroups unavailable elsewhere. For HCV and COPD, additional outcome data were obtained from the EMA European Public Assessment Report (EPAR) and the FDA, respectively, including data on subgroups and mortality. We conclude that data from these grey literature sources have the potential to influence results of systematic reviews and NMAs, and may thus have implications for healthcare decisions. However, it is important to consider carefully the availability, reliability and consequent usability of these data sources in systematic reviews and NMAs. PMID- 27686329 TI - Heavy Metal Concentrations in some Edible Vegetables: A Case Study in Uyo and Ibesikpo Asutan Local Government Areas of Akwa-Ibom State. AB - BACKGROUND: This study assessed the level of heavy metals (Zn, Cu, Mn, Hg and Fe) accumulation in leaves of five vegetables viz: Telfairia occidentalis, Heinsia crinita, Gnetum africanum, Talinum triangulare and Vernonia amygdalina planted in different gardens in Ibesikpo Asutan and Uyo L.G.As in Akwa Ibom State, Nigeria using standard scientific methods. METHODS: Soil samples were obtained at a depth of 0 - 10 cm each at the base of each vegetable using soil auger. RESULTS: The results obtained from this study showed that the nutrient status and heavy metals concentrations of the soil of the two Local Government Areas were not significantly (P= 0.05) different. However, the levels of the heavy metals contents of the leaves of the vegetables were observed to fall within World Health Organisation (WHO) permissible concentration range. This observation indicated that there are little or no anthropogenic activities in or around the garden leading to the emission of heavy metals into the environment. Also, the result attributes the low heavy metals accumulation in the soil and poor translocation to the use of organic supplements in the gardens. CONCLUSION: The finding of this study certifies that there is no risk associated with the consumption of vegetables from these farms. This result is discussed in line with current global trends in pollution management and dietetics. PMID- 27686330 TI - Predicting episodic memory formation for movie events. AB - Episodic memories are long lasting and full of detail, yet imperfect and malleable. We quantitatively evaluated recollection of short audiovisual segments from movies as a proxy to real-life memory formation in 161 subjects at 15 minutes up to a year after encoding. Memories were reproducible within and across individuals, showed the typical decay with time elapsed between encoding and testing, were fallible yet accurate, and were insensitive to low-level stimulus manipulations but sensitive to high-level stimulus properties. Remarkably, memorability was also high for single movie frames, even one year post-encoding. To evaluate what determines the efficacy of long-term memory formation, we developed an extensive set of content annotations that included actions, emotional valence, visual cues and auditory cues. These annotations enabled us to document the content properties that showed a stronger correlation with recognition memory and to build a machine-learning computational model that accounted for episodic memory formation in single events for group averages and individual subjects with an accuracy of up to 80%. These results provide initial steps towards the development of a quantitative computational theory capable of explaining the subjective filtering steps that lead to how humans learn and consolidate memories. PMID- 27686331 TI - A powerful weighted statistic for detecting group differences of directed biological networks. AB - Complex disease is largely determined by a number of biomolecules interwoven into networks, rather than a single biomolecule. Different physiological conditions such as cases and controls may manifest as different networks. Statistical comparison between biological networks can provide not only new insight into the disease mechanism but statistical guidance for drug development. However, the methods developed in previous studies are inadequate to capture the changes in both the nodes and edges, and often ignore the network structure. In this study, we present a powerful weighted statistical test for group differences of directed biological networks, which is independent of the network attributes and can capture the changes in both the nodes and edges, as well as simultaneously accounting for the network structure through putting more weights on the difference of nodes locating on relatively more important position. Simulation studies illustrate that this method had better performance than previous ones under various sample sizes and network structures. One application to GWAS of leprosy successfully identifies the specific gene interaction network contributing to leprosy. Another real data analysis significantly identifies a new biological network, which is related to acute myeloid leukemia. One potential network responsible for lung cancer has also been significantly detected. The source R code is available on our website. PMID- 27686332 TI - Can Lay Community Advisors Improve the Clarity of Research Participant Recruitment Materials and Increase the Likelihood of Participation? AB - Despite decades of effort, lower income people and ethnic minorities continue to be underrepresented as participants in health research. A group of racially and ethnically diverse, lower income community members (Community Advisors on Research Design and Strategies: CARDS(r)) was trained to review study designs and procedures and provide recommendations to researchers for increasing participation and making research materials more understandable to members of underrepresented communities. In this mixed methods study, one participant group (n = 55) was shown research materials (recruitment documents and a consent form) developed by a research team and approved by the local IRB. A second group (n = 45) was shown the same materials after they had also been reviewed and revised by CARDS. Interviews, which included both fixed-response and open-ended questions, were used to assess reactions of participants in both groups to the materials, including their hypothetical willingness to volunteer for the research described. Group differences were examined using the Chi-square distribution test. Proportional difference effect sizes were estimated using arcsine transformation. The qualitative data were subjected to conventional content analysis. Participants in the group shown the recruitment materials revised by CARDS were more likely to say they understood the documents, more likely to ask for more information about the study, and more likely to say they would participate in the research. Results of content analysis suggested a four-phase sequential process for deciding whether to participate in the research. (c) 2016 Wiley Periodicals, Inc. PMID- 27686333 TI - Tapping the archives: the sterol composition of marine sponge species, as determined non-invasively from museum-preserved specimens, reveals biogeographical features. AB - Over 8600 species are currently recorded in the phylum Porifera (sponges). They produce a large diversity of biochemical compounds including sterols, with more than 250 different sterols identified. Some of these sterols are of great interest, due to their use for fingerprinting in ecological and biomarker (molecular fossil) studies. As a large number of identified extant species from biodiversity surveys are housed in museum collections, preserved in ethanol, these present a potentially rich source of identified specimens for comparative lipid analyses. Here, we show that, in at least one species, sterol distributions obtained from the ethanol used to preserve specimens of sponges were representative, and comparable to the sterol distribution obtained from wet frozen and from freeze-dried tissue from the same species. We employed both GC-MS and two-dimensional gas chromatography-time-of-flight mass spectrometry (GC*GC TOFMS), with an improved signal-to-noise ratio for even minor constituents. Analysis of two additional specimens of the same species, but of different provenance, resulted in detection of marked differences in sterol composition, which could be attributed to variations in geography, environmental conditions, microbial communities, diet or cryptic speciation. The possibility of using ethanol from identified, preserved museum sponges could drastically increase the number of available samples. This could enable the study of their sterol complements, and the detailed investigation of differences due to geographical and oceanographic, phylogenetic, and other factors in unprecedented detail.

PMID- 27686335 TI - A Stimuli-Responsive, Binary Reagent System for Rapid Isolation of Protein Biomarkers. AB - Magnetic microbeads exhibit rapid separation characteristics and are widely employed for biomolecule and cell isolations in research laboratories, clinical diagnostics assays, and cell therapy manufacturing. However, micrometer particle diameters compromise biomarker recognition, which leads to long incubation times and significant reagent demands. Here, a stimuli-responsive binary reagent system is presented that combines the nanoscale benefits of efficient biomarker recognition and the microscale benefits of rapid magnetic separation. This system comprises magnetic nanoparticles and polymer-antibody (Ab) conjugates that transition from hydrophilic nanoscale reagents to microscale aggregates in response to temperature stimuli. The binary reagent system was benchmarked against Ab-labeled Dynabeads in terms of biomarker isolation kinetics, assay speed, and reagent needs. Surface plasmon resonance (SPR) measurements showed that polymer conjugation did not significantly alter the Ab's binding affinity or kinetics. ELISA analysis showed that the unconjugated Ab, polymer-Ab conjugates, and Ab-labeled Dynabeads exhibited similar equilibrium dissociation constants (Kd), ~2 nM. However, the binary reagent system isolated HIV p24 antigen from spiked serum specimens (150 pg/mL) much more quickly than Dynabeads, which resulted in shorter binding times by tens of minutes, or about 30-50% shorter overall assay times. The binary reagent system showed improved performance because the Ab molecules were not conjugated to large, solid microparticle surfaces.

PMID- 27686337 TI - Ascending Aortic Elasticity and Related Risk Factors Study on Prehypertension Patients. AB - BACKGROUND: A new feature of coronary computed tomography angiography (CTA) is to estimate ascending aortic elasticity without additional cost, but its applicable benefit for prehypertension patients is still unclear. The aim of this study is to discuss the characteristic of ascending aortic elasticity for specific prehypertension patients and its risk factors. METHODS: Coronary CTA examinations of 398 participants were performed using a 128 slicer CT scanner. The differences of 3 ascending aortic elasticity related indices, including aortic distensibility (AD), aortic compliance (AC), and aortic stiffness (ASI), and anatomical measurements were analyzed among the normal, prehypertension, and primary hypertension groups. RESULTS: No difference was found for normalized minimum cross-sectional diameter and area for the ascending aorta between prehypertension and normal groups. AD, AC, and ASI were significantly different in 3 groups. Between prehypertension and normal groups, AD and AC were found much smaller but no difference were found for ASI; while between prehypertension and hypertension groups, significant differences were found in AD and ASI, and AC was found to a lesser extent. Risk factor study for prehypertension patients indicated that age and systolic pressure were the independent risk factors for AD decline. CONCLUSION: As a byproduct, coronary CTA can provide multiple aortic elasticity related indices for the prehypertension patients, without additional contrast media consumption and radiation dose. It is proofed that the early detection of ascending aortic elasticity index changes, especially for AD are essential for identifying the high-risk individuals in the prehypertension populations.

AB - Second coordination sphere (SCS) effects in proteins are modulated by active site residues and include hydrogen bonding, electrostatic/dipole interactions, steric interactions, and pi-stacking of aromatic residues. In Cyt P450s, extended H bonding networks are located around the proximal cysteinate ligand of the heme, referred to as the 'Cys pocket'. These hydrogen bonding networks are generally believed to regulate the Fe-S interaction. Previous work identified the S(Cys) -> Fe sigma CT transition in the high-spin (hs) ferric form of Cyt P450cam and corresponding Cys pocket mutants by low-temperature (LT) MCD spectroscopy [Biochemistry 50:1053, 2011]. In this work, we have investigated the effect of the hydrogen bond from W409 to the axial Cys ligand of the heme in the hs ferric state (with H4B and L-Arg bound) of rat neuronal nitric oxide synthase oxygenase construct (nNOSoxy) using MCD spectroscopy. For this purpose, wt enzyme and W409 mutants were investigated where the H-bonding network with the axial Cys ligand is perturbed. Overall, the results are similar to Cyt P450cam and show the intense S(Cys) -> Fe sigma CT band in the LT MCD spectrum at about 27,800 cm-1, indicating that this feature is a hallmark of {heme-thiolate} active sites. The discovery of this MCD feature could constitute a new approach to classify {heme thiolate} sites in hs ferric proteins. Finally, the W409 mutants show that the hydrogen bond from this group only has a small effect on the Fe-S(Cys) bond strength, at least in the hs ferric form of the protein studied here. Low temperature MCD spectroscopy is used to investigate the effect of the hydrogen bond from W409 to the axial Cys ligand of the heme in neuronal nitric oxide synthase. The intense S(Cys) -> Fe sigma-CT band is monitored to identify changes in the Fe-S(Cys) bond in wild-type protein and W409 mutants. PMID- 27686339 TI - A new approach to selective brain cooling by a Ranque-Hilsch vortex tube. AB - BACKGROUND: Target temperature management is the single most effective intervention and the gold standard in post-resuscitation care today. However, cooling the whole body below 33-34 degrees C can cause severe complications. Therefore, developing a selective brain cooling (SBC) approach which can be initiated early to induce rapid cooling and maintain the target temperature over 12-24 h before slowly rewarming brain temperature by itself alone would be advantageous. Vortex tubes are simple mechanical devices generating cold air from a stream of compressed air without applied chemical or energy. This study investigated whether blowing cooled air from a vortex tube into the nasal cavities is safe and effective to selectively reduce and maintain before slowly rewarming brain temperature back to normal temperature. METHODS: Experiments were conducted on ten juvenile pigs. Body temperature was measured using an esophageal and a rectal temperature probe while brain temperature with an intraparenchymal thermocouple probe. Cerebral blood flow (CBF) was measured with CT perfusion. RESULTS: Brain temperature dropped below 34 degrees C within 30-40 min while a brain-esophageal temperature difference greater than 3 degrees C was maintained over 6 h. There was no evidence of nasal or nasopharynx mucosal swelling, necrosis, or hemorrhage on MRI examination. CBF first decreased and then stabilized together with brain temperature before increasing to the baseline level during rewarming. CONCLUSIONS: SBC was accomplished by blowing cold air from a vortex tube into the nasal cavities. Due to its portability, the method can be used continuously in resuscitated patients in both in- and out-of-hospital situations without interruption. PMID- 27686340 TI - Functional assessment for elimination of mismatches in nuclear and whole cell extracts obtained from mouse and human blastocysts. AB - Preimplantation embryos may have an increased risk of having mismatches due to the rates of cell proliferation and DNA replication. Elimination of mismatches in human gametes and embryos has not been investigated. In this study we developed a sensitive functional assay to examine the repair or elimination of mismatches in both commercially available cell extracts and extracts obtained from preimplantation embryos. Heteroduplex molecules were constructed using synthetic oligonucleotides. Efficiency of the repair of mismatches was semi-quantitatively analysed by exposure to nuclear/whole cell extracts (as little as 2.5 ug) and extracts obtained from pooled mouse and human blastocysts to investigate the repair capacity in human embryos. A cell free in vitro assay was successfully developed to analyze the repair of mismatches using heteroduplex complexes. The assay was further optimized to analyze repair of mismatches in cell extracts obtained from oocytes and blastocysts using minute amounts of protein. The efficiency of mismatch repair was examined in both mouse and human blastocysts (2.5 ug). The blastocysts were observed to have a lower repair efficiency compared to commercially available nuclear and whole cell extracts. In conclusion, a sensitive, easy, and fast in vitro technique was developed to detect the repair of mismatch efficiency in embryos. PMID- 27686341 TI - The Forgotten Virulence Factor: The 'non-conventional' Hemolysin TlyA And Its Role in Helicobacter pylori Infection. AB - Helicobacter pylori is a human-specific Gram-negative pathogenic bacterium which colonizes the gastric mucosal layer in the stomach causing diseases such as peptic ulcer, adenocarcinoma, and gastric lymphoma. It is estimated that approximately half of the world's population is infected with H. pylori making it the most intensively characterized microbial pathogen up to now. Hemolysis has been suggested to significantly contribute to colonization of the stomach and disease progression by H. pylori. In a number of earlier studies, TlyA was characterized as a putative pore-forming cytolysin. Although a few observations in the literature suggest a role for TlyA as significant virulence factor of H. pylori, the molecular and structural characterization of this protein is much curtailed at present. Given the intensive characterization of numerous H. pylori virulence factors over the past decade, surprisingly little information exists for the TlyA toxin and its significance for pathogenesis. This review provides a brief overview on microbial hemolysis and its role for pathogenesis and discusses recent research efforts aimed at an improved understanding of the role of the 'non-conventional' hemolysin and its associated RNA methyltransferase TlyA from H. pylori. PMID- 27686342 TI - Total antioxidant status and lipid peroxidation with and without in vitro zinc supplementation in infertile men. AB - The aim of this study was to assess the total antioxidant capacity (TAC) and malondialdehyde (MDA) level in infertile men with asthenozoospermia and asthenoteratozoospermia compared to fertile donors, and to examine the effect of zinc on sperm lipid peroxidation and antioxidant status in infertile and fertile men. Semen samples provided by infertile men (n = 38) and fertile donors (controls; n = 12) were exposed to 6 mmol/L of zinc for 2 hr at 37 degrees C. After semen analysis, lipid peroxidation was detected by MDA assay and seminal TAC was assessed by colorimetric method using TAS (total antioxidant status) Kit. TAC was significantly lower in infertile group compared to controls (p = .037). However, lipid peroxidation did not alter in infertile patients compared to controls (p > .05). After in vitro incubation of samples with zinc, a significant increase in TAC level was found only in infertile men (p < .001). Meanwhile, zinc had no effect on sperm lipid peroxidation in both fertile and infertile men (p > .05). Our data indicate that antioxidant treatment based on zinc in vitro supplementation may be helpful to enhance the rate of seminal antioxidant status in infertile men; however, it does not prevent sperm lipid peroxidation. PMID- 27686343 TI - Nitric oxide administration during paediatric cardiopulmonary bypass: a randomised controlled trial. AB - PURPOSE: Cardiopulmonary bypass induces an ischaemia-reperfusion injury and systemic inflammatory response, which contributes to low cardiac output syndrome following cardiac surgery. Exogenous nitric oxide during cardiopulmonary bypass has shown potential to ameliorate such injury. We undertook a large randomised controlled trial to investigate the clinical effects of administering nitric oxide to the cardiopulmonary bypass circuit in children. METHODS: After written informed consent, children were randomised to receive 20 ppm nitric oxide to the gas inflow of the cardiopulmonary bypass oxygenator, or standard conduct of bypass. RESULTS: 101 children received nitric oxide and developed low cardiac output syndrome less frequently (15 vs. 31 %, p = 0.007) than the 97 children who did not receive nitric oxide. This effect was most marked in children aged less than 6 weeks of age (20 vs. 52 %, p = 0.012) and in those aged 6 weeks to 2 years (6 vs. 24 %, p = 0.026), who also had significantly reduced ICU length of stay (43 vs. 84 h, p = 0.031). Low cardiac output syndrome was less frequent following more complex surgeries if nitric oxide was administered (17 vs. 48 %, p = 0.018). ECMO was used less often in the nitric oxide group (1 vs. 8 %, p = 0.014). CONCLUSIONS: Delivery of nitric oxide to the oxygenator gas flow during paediatric cardiopulmonary bypass reduced the incidence of low cardiac output syndrome by varying degrees, according to age group and surgery complexity.

PMID- 27686345 TI - Long-term outcomes in patients with septic shock transfused at a lower versus a higher haemoglobin threshold: the TRISS randomised, multicentre clinical trial. AB - PURPOSE: We assessed the predefined long-term outcomes in patients randomised in the Transfusion Requirements in Septic Shock (TRISS) trial. METHODS: In 32 Scandinavian ICUs, we randomised 1005 patients with septic shock and haemoglobin of 9 g/dl or less to receive single units of leuko-reduced red cells when haemoglobin level was 7 g/dl or less (lower threshold) or 9 g/dl or less (higher threshold) during ICU stay. We assessed mortality rates 1 year after randomisation and again in all patients at time of longest follow-up in the intention-to-treat population (n = 998) and health-related quality of life (HRQoL) 1 year after randomisation in the Danish patients only (n = 777). RESULTS: Mortality rates in the lower- versus higher-threshold group at 1 year were 53.5 % (268/501 patients) versus 54.6 % (271/496) [relative risk 0.97; 95 % confidence interval (CI) 0.85-1.09; P = 0.62]; at longest follow-up (median 21 months), they were 56.7 % (284/501) versus 61.0 % (302/495) (hazard ratio 0.88; 95 % CI 0.75-1.03; P = 0.12). We obtained HRQoL data at 1 year in 629 of the 777 (81 %) Danish patients, and mean differences between the lower- and higher threshold group in scores of physical HRQoL were 0.4 (95 % CI -2.4 to 3.1; P = 0.79) and in mental HRQoL 0.5 (95 % CI -3.1 to 4.0; P = 0.79). CONCLUSIONS: Long term mortality rates and HRQoL did not differ in patients with septic shock and anaemia who were transfused at a haemoglobin threshold of 7 g/dl versus a threshold of 9 g/dl. We may reject a more than 3 % increased hazard of death in the lower- versus higher-threshold group at the time of longest follow-up. PMID- 27686346 TI - Intravenous iron or placebo for anaemia in intensive care: the IRONMAN multicentre randomized blinded trial : A randomized trial of IV iron in critical illness. AB - PURPOSE: Both anaemia and allogenic red blood cell transfusion are common and potentially harmful in patients admitted to the intensive care unit. Whilst intravenous iron may decrease anaemia and RBC transfusion requirement, the safety and efficacy of administering iron intravenously to critically ill patients is uncertain. METHODS: The multicentre, randomized, placebo-controlled, blinded Intravenous Iron or Placebo for Anaemia in Intensive Care (IRONMAN) study was designed to test the hypothesis that, in anaemic critically ill patients admitted to the intensive care unit, early administration of intravenous iron, compared with placebo, reduces allogeneic red blood cell transfusion during hospital stay and increases the haemoglobin level at the time of hospital discharge. RESULTS: Of 140 patients enrolled, 70 were assigned to intravenous iron and 70 to placebo. The iron group received 97 red blood cell units versus 136 red blood cell units in the placebo group, yielding an incidence rate ratio of 0.71 [95 % confidence interval (0.43-1.18), P = 0.19]. Overall, median haemoglobin at hospital discharge was significantly higher in the intravenous iron group than in the placebo group [107 (interquartile ratio IQR 97-115) vs. 100 g/L (IQR 89-111), P = 0.02]. There was no significant difference between the groups in any safety outcome. CONCLUSIONS: In patients admitted to the intensive care unit who were anaemic, intravenous iron, compared with placebo, did not result in a significant lowering of red blood cell transfusion requirement during hospital stay. Patients who received intravenous iron had a significantly higher haemoglobin concentration at hospital discharge. The trial was registered at http://www.anzctr.org.au as # ACTRN12612001249842. PMID- 27686347 TI - Neurally adjusted ventilatory assist as an alternative to pressure support ventilation in adults: a French multicentre randomized trial. AB - PURPOSE: Neurally adjusted ventilatory assist (NAVA) is a ventilatory mode that tailors the level of assistance delivered by the ventilator to the electromyographic activity of the diaphragm. The objective of this study was to compare NAVA and pressure support ventilation (PSV) in the early phase of weaning from mechanical ventilation. METHODS: A multicentre randomized controlled trial of 128 intubated adults recovering from acute respiratory failure was conducted in 11 intensive care units. Patients were randomly assigned to NAVA or PSV. The primary outcome was the probability of remaining in a partial ventilatory mode (either NAVA or PSV) throughout the first 48 h without any return to assist control ventilation. Secondary outcomes included asynchrony index, ventilator free days and mortality. RESULTS: In the NAVA and PSV groups respectively, the proportion of patients remaining in partial ventilatory mode throughout the first 48 h was 67.2 vs. 63.3 % (P = 0.66), the asynchrony index was 14.7 vs. 26.7 % (P < 0.001), the ventilator-free days at day 7 were 1.0 day [1.0-4.0] vs. 0.0 days [0.0-1.0] (P < 0.01), the ventilator-free days at day 28 were 21 days [4-25] vs. 17 days [0-23] (P = 0.12), the day-28 mortality rate was 15.0 vs. 22.7 % (P = 0.21) and the rate of use of post-extubation noninvasive mechanical ventilation was 43.5 vs. 66.6 % (P < 0.01). CONCLUSIONS: NAVA is safe and feasible over a prolonged period of time but does not increase the probability of remaining in a partial ventilatory mode. However, NAVA decreases patient-ventilator asynchrony and is associated with less frequent application of post-extubation noninvasive mechanical ventilation.

PMID- 27686350 TI - Improving outcomes after critical illness: harder than we thought! PMID- 27686349 TI - Restricting volumes of resuscitation fluid in adults with septic shock after initial management: the CLASSIC randomised, parallel-group, multicentre feasibility trial. AB - PURPOSE: We assessed the effects of a protocol restricting resuscitation fluid vs. a standard care protocol after initial resuscitation in intensive care unit (ICU) patients with septic shock. METHODS: We randomised 151 adult patients with septic shock who had received initial fluid resuscitation in nine Scandinavian ICUs. In the fluid restriction group fluid boluses were permitted only if signs of severe hypoperfusion occurred, while in the standard care group fluid boluses were permitted as long as circulation continued to improve. RESULTS: The co primary outcome measures, resuscitation fluid volumes at day 5 and during ICU stay, were lower in the fluid restriction group than in the standard care group [mean differences -1.2 L (95 % confidence interval -2.0 to -0.4); p < 0.001 and 1.4 L (-2.4 to -0.4) respectively; p < 0.001]. Neither total fluid inputs and balances nor serious adverse reactions differed statistically significantly between the groups. Major protocol violations occurred in 27/75 patients in the fluid restriction group. Ischaemic events occurred in 3/75 in the fluid restriction group vs. 9/76 in the standard care group (odds ratio 0.32; 0.08 1.27; p = 0.11), worsening of acute kidney injury in 27/73 vs. 39/72 (0.46; 0.23 0.92; p = 0.03), and death by 90 days in 25/75 vs. 31/76 (0.71; 0.36-1.40; p = 0.32). CONCLUSIONS: A protocol restricting resuscitation fluid successfully reduced volumes of resuscitation fluid compared with a standard care protocol in adult ICU patients with septic shock. The patient-centred outcomes all pointed towards benefit with fluid restriction, but our trial was not powered to show differences in these exploratory outcomes. TRIAL REGISTRATION: NCT02079402. PMID- 27686351 TI - Improvement in functional abilities at ICU discharge is feasible without prolongation of the length of stay ICU. PMID- 27686352 TI - The effects of performance status one week before hospital admission on the outcomes of critically ill patients. AB - PURPOSE: To assess the impact of performance status (PS) impairment 1 week before hospital admission on the outcomes in patients admitted to intensive care units (ICU). METHODS: Retrospective cohort study in 59,693 patients (medical admissions, 67 %) admitted to 78 ICUs during 2013. We classified PS impairment according to the Eastern Cooperative Oncology Group (ECOG) scale in absent/minor (PS = 0-1), moderate (PS = 2) or severe (PS = 3-4). We used univariate and multivariate logistic regression analyses to investigate the association between PS impairment and hospital mortality. RESULTS: PS impairment was moderate in 17.3 % and severe in 6.9 % of patients. The hospital mortality was 14.4 %. Overall, the worse the PS, the higher the ICU and hospital mortality and length of stay. In addition, patients with worse PS were less frequently discharged home. PS impairment was associated with worse outcomes in all SAPS 3, Charlson Comorbidity Index and age quartiles as well as according to the admission type. Adjusting for other relevant clinical characteristics, PS impairment was associated with higher hospital mortality (odds-ratio (OR) = 1.96 (95 % CI 1.63-2.35), for moderate and OR = 4.22 (3.32-5.35), for severe impairment). The effects of PS on the outcome were particularly relevant in the medium range of severity-of-illness. These results were consistent in the subgroup analyses. However, adding PS impairment to the SAPS 3 score improved only slightly its discriminative capability. CONCLUSION: PS impairment was associated with worse outcomes independently of other markers of chronic health status, particularly for patients in the medium range of severity of illness.

PMID- 27686353 TI - The optimal target for acute glycemic control in critically ill patients: a network meta-analysis. AB - PURPOSE: The optimal target blood glucose concentration for acute glycemic control remains unclear because few studies have directly compared 144-180 with 110-144 or >180 mg/dL. Accordingly, we performed a network meta-analysis to compare four different target blood glucose levels (<110, 110-144, 144-180, and >180 mg/dL) in terms of the benefit and risk of insulin therapy. METHODS: We included all of the studies from three systematic reviews and searched the PubMed and Cochrane databases for other studies investigating glucose targets among critically ill patients. The primary outcome was hospital mortality, and the secondary outcomes were sepsis or bloodstream infection and the risk of hypoglycemia. Network meta-analysis to identify an optimal target glucose concentration. RESULTS: The network meta-analysis included 18,098 patients from 35 studies. There were no significant differences in the risk of mortality and infection among the four blood glucose ranges overall or in subgroup analysis. Conversely, target concentrations of <110 and 110-144 mg/dL were associated with a four to ninefold increase in the risk of hypoglycemia compared with 144-180 and >180 mg/dL. However, there were no significant differences between the target concentrations of 144-180 and >180 mg/dL. CONCLUSIONS: This network meta-analysis found no significant difference in the risk of mortality and infection among four target blood glucose ranges in critically ill patients, but indicated that target blood glucose levels of <110 and 110-144 mg/dL were associated with a higher risk of hypoglycemia than target levels of 144-180 and >180 mg/dL. Further studies are required to refute or confirm our findings. PMID- 27686355 TI - Incidence of severe sepsis and septic shock in German intensive care units: the prospective, multicentre INSEP study. AB - PURPOSE: To estimate the incidence density, point prevalence and outcome of severe sepsis and septic shock in German intensive care units (ICUs). METHODS: In a prospective, multicentre, longitudinal observational study, all patients already on the ICU at 0:00 on 4 November 2013 and all patients admitted to a participating ICU between 0:00 on 4 November 2013 and 2359 hours on 1 December 2013 were included. The patients were followed up for the occurrence of severe sepsis or septic shock (SEPSIS-1 definitions) during their ICU stay. RESULTS: A total of 11,883 patients from 133 ICUs at 95 German hospitals were included in the study, of whom 1503 (12.6 %) were diagnosed with severe sepsis or septic shock. In 860 cases (57.2 %) the infections were of nosocomial origin. The point prevalence was 17.9 % (95 % CI 16.3-19.7).The calculated incidence rate of severe sepsis or septic shock was 11.64 (95 % CI 10.51-12.86) per 1000 ICU days. ICU mortality in patients with severe sepsis/septic shock was 34.3 %, compared with 6 % in those without sepsis. Total hospital mortality of patients with severe sepsis or septic shock was 40.4 %. Classification of the septic shock patients using the new SEPSIS-3 definitions showed higher ICU and hospital mortality (44.3 and 50.9 %). CONCLUSIONS: Severe sepsis and septic shock continue to be a frequent syndrome associated with high hospital mortality. Nosocomial infections play a major role in the development of sepsis. This study presents a pragmatic, affordable and feasible method for the surveillance of sepsis epidemiology. Implementation of the new SEPSIS-3 definitions may have a major effect on future epidemiological data.

AB - To validate the proxy version of the Quality of Life after Brain Injury (QOLIBRI) questionnaire to utilize caregivers for comparison and to evaluate the correspondence between patients' self-perceived and caregivers' perception of patients' Health-Related Quality of Life (HRQoL). Ninety-two patients with severe TBI and their main caregivers were enrolled. Patients' and caregivers' HRQoL was assessed by the Patient-QOLIBRI (Pt-QOLIBRI) and the Proxy-QOLIBRI (Pro-QOLIBRI), respectively. The Pro-QOLIBRI is a modified version of the QOLIBRI to investigate caregivers' perception of patients' HRQoL (Pro-QOLIBRIpatient-centered), and their degree of satisfaction and botheredness (Pro-QOLIBRIcaregiver centered). The patients' disability and their social reintegration was investigated by means of Glasgow Outcome Scale Extended and Community Integration Questionnaire. Pro QOLIBRI has good internal consistency and homogeneity. There was also positive correlation between the level of satisfaction measured by Pro-QOLIBRI but not by Pt-QOLIBRI, and the disability severity and social integration of the patients. The comparison between the Pt-QOLIBRI and Pro-QOLIBRI confirmed the usefulness of the Pro-QOLIBRI, especially the caregiver-centered version, to predict the social reintegration of survivors. To our knowledge this is the first study that correlates the HRQoL of survivors, as self-perceived and as perceived by the caregivers with social reintegration. PMID- 27686363 TI - Is Hepatitis Delta infections important in Brazil? AB - BACKGROUND: The Hepatitis Delta Virus (HDV) can increase the incidence of fulminant hepatitis. For this infection occurs, the host must also be infected with Hepatitis B Virus. Previous studies demonstrated the endemicity and near exclusivity of this infection in the Amazon region, and as a consequence of the difficulty in accessing this area we used dried blood spots (DBS) in sample collection. The aims of this study were to investigate the presence of recombination, to analyze the epidemiology, ancestry and evolutionary pressures on HDV in Brazil. METHODS: Blood samples from 50 individuals were collected using dried-blood spots (DBS 903, Whatman), and sent via regular mail to Retrovirology Laboratory from Federal University of Sao Paulo, where the samples were processed. In the analysis the following software were used: PhyML, RDP, BEAST, jModelTest and CODEML. RESULTS: Our results confirm the prevalence of HDV-3 in the Amazon region of Brazil, with the absence of inter-genotypic recombination. It was identified a positive selection in probable epitopes of HDV on B lymphocytes that might indicate that the virus is changing to escape the humoral response of the host. The analysis of the time of the most common ancestor demonstrated the exponential growth of this virus in late 1970s that lasted until 1995, after which it remained constant. It was also observed a probable founder effect in two cities, which demonstrate the need to focus on prevention methods against HBV/HDV infection. CONCLUSION: We confirmed the prevalence of HDV-3 in the Amazon region of Brazil, without inter-genotypic recombination. The analysis of the time of the most common ancestor showed that this infection remain constant in the studied area. Taking into account the probable founder effect established in the cities of Rio Branco and Porto Velho, a focus on preventive methods is recommended against these infections. PMID- 27686364 TI - Charcot-Marie-Tooth disease type 2G redefined by a novel mutation in LRSAM1. AB - OBJECTIVE: To identify the unknown genetic cause in a large pedigree previously classified with a distinct form of axonal Charcot-Marie-Tooth disease type 2G (CMT2G) and to explore its transcriptional consequences. METHODS: Clinical reevaluation of the pedigree was performed, followed by linkage analysis with the redefined disease statuses, and whole genome and exome sequencing. The impact of the mutation was investigated by immunoblotting and transcriptome sequencing. RESULTS: Thirteen affected individuals over 3 generations displayed mild and quiescent lower-limb axonal sensorimotor neuropathy. Magnetic resonance imaging (MRI) of lower-limb musculature systematically showed fatty atrophy in clinical and subclinical mutation carriers. We redefined the disease-linked region to chr9q31.3-q34.2 and subsequently identified a novel missense variant in the E3 ubiquitin-protein ligase LRSAM1 (p.Cys694Tyr). Unlike previous reports, we demonstrated in patients' lymphoblasts that the mutation does not influence overall protein levels of LRSAM1, nor of its ubiquitylation target TSG101. The mutation is associated with several transcriptional changes, including a significant upregulation of another E3 ubiquitin-protein ligase, NEDD4L, and of TNFRSF21, a key regulator of axonal degeneration. INTERPRETATION: Our findings demonstrate that the isolated genetic entity CMT2G is caused by a missense mutation in LRSAM1 and should be reclassified as CMT2P. MRI of lower-limb musculature can be used to detect minimal signs of the disease. Transcriptome analysis of patients' cells highlights novel molecular players associated with LRSAM1 dysfunction, and reveals pathways and therapeutic targets shared with amyotrophic lateral sclerosis and Alzheimer disease.

AB - Metformin, belonging to a class of drugs called biguanides, is the recommended first-line treatment for overweight patients with type 2 diabetes mellitus. It has multiple mechanisms of action, such as reduction of gluconeogenesis, increases peripheral uptake of glucose, and decreases fatty acid oxidation. However, a potential serious complication, defined metformin-associated lactic acidosis (MALA), is related to increased plasma lactate levels, linked to an elevated plasma metformin concentrations and/or a coexistent condition altering lactate production or clearance. The mortality rate for MALA approaches 50% and metformin has been contraindicated in moderate and severe renal impairment, to minimize its potential toxic levels. Nevertheless, metformin prescription or administration, despite the presence of contraindications or precipitating factors for MALA, was a common topic highlighted in all reviewed papers. Routine assessment of metformin plasma concentration is not easily available in all laboratories, but plasma metformin concentrations measured in the emergency room could ensure the correct diagnosis, eliminating metformin as the cause of lactic acidosis if low plasma levels occurred. Renal replacement therapies have been successfully employed to achieve the correction of metabolic acidosis and rapidly remove metformin and lactate, but the optimal treatment modality for MALA is still controversial.

AB - BACKGROUND: Antibiotics are advised in most guidelines on acute diverticulitis, despite a lack of evidence to support their routine use. This trial compared the effectiveness of a strategy with or without antibiotics for a first episode of uncomplicated acute diverticulitis. METHODS: Patients with CT-proven, primary, left-sided, uncomplicated, acute diverticulitis were included at 22 clinical sites in the Netherlands, and assigned randomly to an observational or antibiotic treatment strategy. The primary endpoint was time to recovery during 6 months of follow-up. Main secondary endpoints were readmission rate, complicated, ongoing and recurrent diverticulitis, sigmoid resection and mortality. Intention-to-treat and per-protocol analyses were done. RESULTS: A total of 528 patients were included. Median time to recovery was 14 (i.q.r. 6-35) days for the observational and 12 (7-30) days for the antibiotic treatment strategy, with a hazard ratio for recovery of 0.91 (lower limit of 1-sided 95 per cent c.i. 0.78; P = 0.151). No significant differences between the observation and antibiotic treatment groups were found for secondary endpoints: complicated diverticulitis (3.8 versus 2.6 per cent respectively; P = 0.377), ongoing diverticulitis (7.3 versus 4.1 per cent; P = 0.183), recurrent diverticulitis (3.4 versus 3.0 per cent; P = 0.494), sigmoid resection (3.8 versus 2.3 per cent; P = 0.323), readmission (17.6 versus 12.0 per cent; P = 0.148), adverse events (48.5 versus 54.5 per cent; P = 0.221) and mortality (1.1 versus 0.4 per cent; P = 0.432). Hospital stay was significantly shorter in the observation group (2 versus 3 days; P = 0.006). Per protocol analyses were concordant with the intention-to-treat analyses. CONCLUSION: Observational treatment without antibiotics did not prolong recovery and can be considered appropriate in patients with uncomplicated diverticulitis.

AB - E-health has experienced a dynamic development across the European Union in the recent years and enjoys support from the European Commission that seeks to achieve interoperability of national healthcare systems in order to facilitate free movement. Differences that can be observed between the member states in legal regulations, cultural approaches and technological solutions may hinder this process. This study compares the legal standing of e-health in Denmark, Poland, Spain and the UK, along with key legal acts and their implications. The academic literature review along with an analysis of materials found through the desk study research (reports, legal acts, press articles, governmental web pages and so on) was performed in order to identify aspects relevant to e-health interoperability. The approach to legal regulation of e-health substantially differs by country. So do the procedures that they have developed regarding the requirement for patient's consent for the processing of their data, their rights to access to the medical data, to change the data, data confidentiality and types of electronic health records. The principles governing the assignment of responsibility for data protection are also different. These legal and technological differences must be reconciled if interoperability of European national e-health systems is to be achieved. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27686368 TI - Classification and regression tree analysis of acute-on-chronic hepatitis B liver failure: Seeing the forest for the trees. AB - At present, there is no ideal model for predicting the short-term outcome of patients with acute-on-chronic hepatitis B liver failure (ACHBLF). This study aimed to establish and validate a prognostic model by using the classification and regression tree (CART) analysis. A total of 1047 patients from two separate medical centres with suspected ACHBLF were screened in the study, which were recognized as derivation cohort and validation cohort, respectively. CART analysis was applied to predict the 3-month mortality of patients with ACHBLF. The accuracy of the CART model was tested using the area under the receiver operating characteristic curve, which was compared with the model for end-stage liver disease (MELD) score and a new logistic regression model. CART analysis identified four variables as prognostic factors of ACHBLF: total bilirubin, age, serum sodium and INR, and three distinct risk groups: low risk (4.2%), intermediate risk (30.2%-53.2%) and high risk (81.4%-96.9%). The new logistic regression model was constructed with four independent factors, including age, total bilirubin, serum sodium and prothrombin activity by multivariate logistic regression analysis. The performances of the CART model (0.896), similar to the logistic regression model (0.914, P=.382), exceeded that of MELD score (0.667, P<.001). The results were confirmed in the validation cohort. We have developed and validated a novel CART model superior to MELD for predicting three-month mortality of patients with ACHBLF. Thus, the CART model could facilitate medical decision-making and provide clinicians with a validated practical bedside tool for ACHBLF risk stratification.

AB - OBJECTIVE: Persistent postural-perceptual dizziness (PPPD) is a common cause of chronic dizziness, but only a few studies have reported its clinical characteristics, and no related research has been performed in China. Therefore, the purpose of this study was to analyze the characteristics of PPPD for the first time in China. DESIGN: Data was collected from all patients during standard clinical practice, and further to evaluate the characteristics of PPPD comparing with the control group. STUDY SAMPLE: A total of 43 patients diagnosed with PPPD were selected as the study group for analysis. RESULTS: Women were significantly more represented in the study group than men, and in the majority of cases the age of onset was in middle-age, and sleep quality was clearly decreased compared with controls, with more statistically significantly higher levels of anxiety. Personality analysis identified that neuroticism was significantly higher than in controls. CONCLUSIONS: In this sample we showed that PPPD was more represented in female patients, the age of onset was 40-60 years old, the majority of patients had sleep disorders, anxiety was the main mood disorder to be identified, and personality analysis found that neurotic personality may be the risk factor for developing PPPD. Further large scale studies are suggested in China. PMID- 27686370 TI - Nutritional status and complementary feeding among HIV-exposed infants: a prospective cohort study. AB - Complementary feeding is crucial for improving child survival and promoting growth and development, particularly among HIV-exposed children who have higher risk of morbidity and mortality than their un-exposed peers. This prospective study employed an infant and child feeding index (ICFI) to measure complementary feeding and determine its association with nutritional status among 2092 HIV exposed infants followed from 6 to 24 months of age in Dar es Salaam, Tanzania. The ICFI measured both quality and quantity of complementary feeding, including current breastfeeding status, food consistency, dietary diversity scores (DDS), food group frequency score, and meal frequency. The ICFI score ranged from 0 to 9; the median score was 6 (Inter-Quartile Range, IQR= 4-7). After adjusting for potential confounders, high ICFI scores were associated with reduced risk of stunting (high vs. low tertile hazard ratio, HR: 0.72; 95% confidence interval, CI: 0.57, 0.91; P< 0.01) and underweight (high vs. low tertile HR: 0.79; 95% CI: 0.61, 1.02; P= 0.07). Low DDS were associated with higher risk of stunting (low vs. high tertile HR: 1.59; 95% CI: 1.23, 2.07; P< 0.01) and underweight (low vs. high tertile HR: 1.48; 95% CI: 1.12, 1.96; P= 0.01). In this setting, high DDS and ICFI scores were protective of stunting and underweight. We recommend for nutrition programs in low-income countries to emphasize educating HIV-exposed children's caregivers on the importance of dietary diversity and optimal complementary feeding to improve nutritional status in this important subpopulation. PMID- 27686371 TI - To image or not to image? A cost-effectiveness analysis of MRI for patients with asymmetric sensorineural hearing loss. AB - OBJECTIVES/HYPOTHESIS: Our objective was to perform an economic analysis evaluating whether ordering a magnetic resonance imaging (MRI) is a cost effective practice in the workup of undifferentiated asymmetric sensorineural hearing loss (ASNHL). Use of T1 gadolinium-weighted MR (GdT1W) and T2 weighted MR without contrast (T2MR) was each examined. METHODS: The incremental cost effectiveness ratio (ICER) of MR imaging among ASNHL patients was evaluated using a decision tree. We calculated what the probability of having a cerebellopontine angle/internal auditory canal lesion would have to be to make MR more cost effective than observation. The decision pathways included observation, GdT1W, and T2MR. The probability of detecting a lesion and associated costs were employed in constructing our tree. Missing a mass in the observation branch was considered to have an effectiveness of 0. The costs and probabilities were extracted from previously published studies. RESULTS: The ICERs of pursuing GdT1W and T2MR were $27,660 and $15,943, respectively, both below the widely accepted willingness to pay (WTP) thresholds of $30,000 and $50,000. Probabilistic sensitivity analysis with Monte Carlo simulations for GdT1W showed that it is more cost-effective than no imaging, with 54.4% and 83.5% certainty at $30,000 and $50,000 WTP thresholds. Probabilistic sensitivity analysis with Monte Carlo simulations for T2MR showed that it is more cost-effective than no imaging, with 75.2% and 92.6% certainty at $30,000 and $50,000 WTP thresholds. CONCLUSION: This economic evaluation strongly supports pursuing MRI in patients with documented ASNHL as a cost-effective strategy. Both GdT1W and T2MR are more cost-effective than observation. Furthermore, noncontrast T2 imaging may be the more cost effective modality of these two techniques. LEVEL OF EVIDENCE: 2c. Laryngoscope, 127:939-944, 2017. PMID- 27686372 TI - Interleukin-15 enhances the proliferation, stimulatory phenotype, and antitumor effector functions of human gamma delta T cells. AB - BACKGROUND: Adoptive immunotherapy is gaining momentum to fight malignancies, whereby gammadelta T cells have received recent attention as an alternative cell source as to natural killer cells and alphabeta T cells. The advent of gammadelta T cells is largely due to their ability to recognize and target tumor cells using both innate characteristic and T cell receptor (TCR)-mediated mechanisms, their capacity to enhance the generation of antigen-specific T cell responses, and their potential to be used in an autologous or allogeneic setting. METHODS: In this study, we explored the beneficial effect of the immunostimulatory cytokine interleukin (IL)-15 on purified gammadelta T cells and its use as a stimulatory signal in the ex vivo expansion of gammadelta T cells for adoptive transfer. The expansion protocol was validated both with immune cells of healthy individuals and acute myeloid leukemia patients. RESULTS: We report that the addition of IL 15 to gammadelta T cell cultures results in a more activated phenotype, a higher proliferative capacity, a more pronounced T helper 1 polarization, and an increased cytotoxic capacity of gammadelta T cells. Moreover gammadelta T cell expansion starting with peripheral blood mononuclear cells from healthy individuals and acute myeloid leukemia patients is boosted in the presence of IL 15, whereby the antitumor properties of the gammadelta T cells are strengthened as well. CONCLUSIONS: Our results support the rationale to explore the use of IL 15 in clinical adoptive therapy protocols exploiting gammadelta T cells. PMID- 27686373 TI - Regenerate bone stimulation following limb lengthening: a meta-analysis. AB - BACKGROUND: Limb lengthening with external fixation is performed to treat patients with leg length discrepancy or short stature. Although the procedure has a high rate of success, one potential drawback from limb lengthening is the amount of time spent in the fixation device while regenerate bone consolidates. Although some studies have assessed different treatment modalities, there has not been a study that has systematically evaluated whether low intensity pulsed ultrasound (LIPUS) or pulsed electromagnetic fields (PEMF) have significant effects on regenerate bone growth. The purpose of this study was to evaluate these two non-pharmacological treatment options to stimulate regenerate bone, and to assess whether they affect the treatment time in limb lengthening. METHODS: Utilizing the electronic databases Medline, Embase and Ovid, we performed a literature search for studies describing the application of LIPUS or PEMF following limb lengthening. With the aid of a statistical software package, Forest-Plots were generated to compare the differences in bone healing index with and without the use of regenerate bone stimulation. RESULTS: A total of 7 studies assessed these two bone stimulation modalities in a cohort of 153 patients. Overall, the mean healing index was 11.7 days/cm faster when using bone stimulation that in the comparison cohorts (33.7 vs 45.4 day, standardized mean difference of 1.16; p = 0.003). CONCLUSION: Amongst the drawbacks from limb lengthening is the relatively high rate of non- and delayed-union. Several methods, both pharmacological and non-pharmacological, have been investigated for their potential to stimulate the growth of regenerate bone. After systematically evaluating the limited and heterogeneous current literature, we found that LIPUS and PEMF both decreased the time for bone healing (healing index in days/cm) of the newly formed regenerate bone in an adequately selected cohort of patients that underwent limb lengthening. However, a high number of complications should be noted, which could be attributed to the lengthening procedure or to the additional bone stimulation. PROSPERO REGISTRATION NUMBER: CRD42016039024. PMID- 27686374 TI - Impaired pulmonary endothelial barrier function in sickle cell mice. PMID- 27686375 TI - The role of ZAP70 kinase in acute lymphoblastic leukemia infiltration into the central nervous system. AB - Central nervous system infiltration and relapse are poorly understood in childhood acute lymphoblastic leukemia. We examined the role of zeta-chain associated protein kinase 70 in preclinical models of central nervous system leukemia and performed correlative studies in patients. Zeta-chain-associated protein kinase 70 expression in acute lymphoblastic leukemia cells was modulated using short hairpin ribonucleic acid-mediated knockdown or ectopic expression. We show that zeta-chain-associated protein kinase 70 regulates CCR7/CXCR4 via activation of extracellular signal-regulated kinases. High expression of zeta chain-associated protein kinase 70 in acute lymphoblastic leukemia cells resulted in a higher proportion of central nervous system leukemia in xenografts as compared to zeta-chain-associated protein kinase 70 low expressing counterparts. High zeta-chain-associated protein kinase 70 also enhanced the migration potential towards CCL19/CXCL12 gradients in vitro CCR7 blockade almost abrogated homing of acute lymphoblastic leukemia cells to the central nervous system in xenografts. In 130 B-cell precursor acute lymphoblastic leukemia and 117 T-cell acute lymphoblastic leukemia patients, zeta-chain-associated protein kinase 70 and CCR7/CXCR4 expression levels were significantly correlated. Zeta-chain associated protein kinase 70 expression correlated with central nervous system disease in B-cell precursor acute lymphoblastic leukemia, and CCR7/CXCR4 correlated with central nervous system involvement in T-cell acute lymphoblastic leukemia patients. In multivariate analysis, zeta-chain-associated protein kinase 70 expression levels in the upper third and fourth quartiles were associated with central nervous system involvement in B-cell precursor acute lymphoblastic leukemia (odds ratio=7.48, 95% confidence interval, 2.06-27.17; odds ratio=6.86, 95% confidence interval, 1.86-25.26, respectively). CCR7 expression in the upper fourth quartile correlated with central nervous system positivity in T-cell acute lymphoblastic leukemia (odds ratio=11.00, 95% confidence interval, 2.00-60.62). We propose zeta-chain-associated protein kinase 70, CCR7 and CXCR4 as markers of central nervous system infiltration in acute lymphoblastic leukemia warranting prospective investigation. PMID- 27686376 TI - Improving results of allogeneic hematopoietic cell transplantation for adults with acute lymphoblastic leukemia in first complete remission: an analysis from the Acute Leukemia Working Party of the European Society for Blood and Marrow Transplantation. AB - Allogeneic hematopoietic cell transplantation is widely used to treat adults with high-risk acute lymphoblastic leukemia. The aim of this study was to analyze whether the results changed over time and to identify prognostic factors. Adult patients treated between 1993 and 2012 with myeloablative allogeneic hematopoietic cell transplantation from HLA matched sibling (n=2681) or unrelated (n=2178) donors in first complete remission were included. For transplantations from sibling donors performed between 2008 and 2012, 2-year probabilities of overall survival were: 76% (18-25 years old), 69% (26-35 and 36-45 years old) and 60% (46-55 years old). Among recipients of transplantations from unrelated donors, the respective survival rates were 66%, 70%, 61%, and 62%. In comparison with the 1993-2007 period, significant improvements were observed for all age groups except for the 26-35-year old patients. In a multivariate model, transplantations performed between 2008 and 2012, when compared to 1993-2007, were associated with significantly reduced risks of non-relapse mortality (Hazard Ratio 0.77, P=0.00006), relapse (Hazard Ratio 0.85, P=0.007), treatment failure (Hazard Ratio 0.81, P<0.00001), and overall mortality (Hazard Ratio 0.79, P<0.00001). In the analysis restricted to transplantations performed between 2008 and 2012, the use of total body irradiation-based conditioning was associated with reduced risk of relapse (Hazard Ratio 0.48, P=0.004) and treatment failure (Hazard Ratio 0.63, P=0.02). We conclude that results of allogeneic hematopoietic cell transplantation for adults with acute lymphoblastic leukemia improved significantly over time. Total body irradiation should be considered as the preferable type of myeloablative conditioning. PMID- 27686377 TI - Risk of thrombosis according to need of phlebotomies in patients with polycythemia vera treated with hydroxyurea. AB - Hematocrit control below 45% is associated with a lower rate of thrombosis in polycythemia vera. In patients receiving hydroxyurea, this target can be achieved with hydroxyurea alone or with the combination of hydroxyurea plus phlebotomies. However, the clinical implications of phlebotomy requirement under hydroxyurea therapy are unknown. The aim of this study was to evaluate the need for additional phlebotomies during the first five years of hydroxyurea therapy in 533 patients with polycythemia vera. Patients requiring 3 or more phlebotomies per year (n=85, 16%) showed a worse hematocrit control than those requiring 2 or less phlebotomies per year (n=448, 84%). There were no significant differences between the two study groups regarding leukocyte and platelet counts. Patients requiring 3 or more phlebotomies per year received significantly higher doses of hydroxyurea than the remaining patients. A significant higher rate of thrombosis was found in patients treated with hydroxyurea plus 3 or more phlebotomies per year compared to hydroxyurea with 0-2 phlebotomies per year (20.5% vs. 5.3% at 3 years; P<0.0001). In multivariate analysis, independent risk factors for thrombosis were phlebotomy dependency (HR: 3.3, 95%CI: 1.5-6.9; P=0.002) and thrombosis at diagnosis (HR: 4.7, 95%CI: 2.3-9.8; P<0.0001). The proportion of patients fulfilling the European LeukemiaNet criteria of resistance/intolerance to hydroxyurea was significantly higher in the group requiring 3 or more phlebotomies per year (18.7% vs. 7.1%; P=0.001) mainly due to extrahematologic toxicity. In conclusion, phlebotomy requirement under hydroxyurea therapy identifies a subset of patients with increased proliferation of polycythemia vera and higher risk of thrombosis. PMID- 27686378 TI - An accurate, simple prognostic model consisting of age, JAK2, CALR, and MPL mutation status for patients with primary myelofibrosis. AB - In most patients with primary myelofibrosis, one of three mutually exclusive somatic mutations is detected. In approximately 60% of patients, the Janus kinase 2 gene is mutated, in 20%, the calreticulin gene is mutated, and in 5%, the myeloproliferative leukemia virus gene is mutated. Although patients with mutated calreticulin or myeloproliferative leukemia genes have a favorable outcome, and those with none of these mutations have an unfavorable outcome, prognostication based on mutation status is challenging due to the heterogeneous survival of patients with mutated Janus kinase 2. To develop a prognostic model based on mutation status, we screened primary myelofibrosis patients seen at the MD Anderson Cancer Center, Houston, USA, between 2000 and 2013 for the presence of Janus kinase 2, calreticulin, and myeloproliferative leukemia mutations. Of 344 primary myelofibrosis patients, Janus kinase 2V617F was detected in 226 (66%), calreticulin mutation in 43 (12%), and myeloproliferative leukemia mutation in 16 (5%); 59 patients (17%) were triple-negatives. A 50% cut-off dichotomized Janus kinase 2-mutated patients into those with high Janus kinase 2V617F allele burden and favorable survival and those with low Janus kinase 2V617F allele burden and unfavorable survival. Patients with a favorable mutation status (high Janus kinase 2V617F allele burden/myeloproliferative leukemia/calreticulin mutation) and aged 65 years or under had a median survival of 126 months. Patients with one risk factor (low Janus kinase 2V617F allele burden/triple-negative or age >65 years) had an intermediate survival duration, and patients aged over 65 years with an adverse mutation status (low Janus kinase 2V617F allele burden or triple negative) had a median survival of only 35 months. Our simple and easily applied age- and mutation status-based scoring system accurately predicted the survival of patients with primary myelofibrosis. PMID- 27686379 TI - Class P dye-decolorizing peroxidase gene: Degenerated primers design and phylogenetic analysis. AB - Dye-decolorizing peroxidases (DyPs) were classified as a new family of heme peroxidase in 2007. Produced by various bacteria, they are the first bacterial enzymes known able to degrade lignin and dyes, for which their application in waste treatment and pretreatment of lignocellulosic biomass could be envisaged. In this work, a PCR primer pair was created and tested that enabled the detection and quantification of a wide range of bacterial genes of P class DyP in complex matrices. In addition, a phylogenetic tree was built with all available sequences of DyP genes available, offering a first overview of their presence in the bacteria kingdom. PMID- 27686380 TI - Effects of field conditions on fecal microbiota. AB - Gut microbiota can provide great insight into host health, and studies of the gut microbiota in wildlife are becoming more common. However, the effects of field conditions on gut microbial samples are unknown. This study addresses the following questions: 1) How do environmental factors such as sunlight and insect infestations affect fecal microbial DNA? 2) How does fecal microbial DNA change over time after defecation? 3) How does storage method affect microbial DNA? Fresh fecal samples were collected, pooled, and homogenized from a family group of 6 spider monkeys, Ateles geoffroyi. Samples were then aliquoted and subjected to varying light conditions (shade, sun), insect infestations (limited or not limited by netting over the sample), and sample preservation methods (FTA - Fast Technology for Analysis of nucleic acid - cards, or freezing in liquid nitrogen then storing at -20 degrees C). Changes in the microbial communities under these conditions were assessed over 24h. Time and preservation method both effected fecal microbial community diversity and composition. The effect size of these variables was then assessed in relation to fecal microbial samples from 2 other primate species (Rhinopithecus bieti and R. brelichi) housed at different captive institutions. While the microbial community of each primate species was significantly different, the effects of time and preservation method still remained significant indicating that these effects are important considerations for fieldwork. PMID- 27686381 TI - Intestinal angina in a patient with hypertrophic obstructive cardiomyopathy: a case report. AB - BACKGROUND: Intestinal angina is characterized by recurrent postprandial abdominal pain and anorexia. Commonly, these symptoms are caused by severe stenosis of at least two vessels among the celiac and mesenteric arteries. However, intestinal perfusion is affected not only by the degree of arterial stenosis but also by systemic perfusion. We experienced a unique case of intestinal angina caused by relatively mild stenosis of the abdominal arteries complicated with hypertrophic obstructive cardiomyopathy. CASE PRESENTATION: We report an 86-year old Japanese man with hypertrophic obstructive cardiomyopathy and advanced atrioventricular block who was diagnosed with intestinal angina. Computed tomography showed mild stenosis of the celiac artery and severe stenosis of the inferior mesenteric artery, and these lesions were relatively mild compared with other reports. A dual-chamber pacemaker with right ventricular apical pacing was implanted to improve the obstruction of the left ventricular outflow tract. After implantation, the patient's abdominal symptoms diminished markedly, and improvement of the left ventricular outflow tract obstruction was observed. CONCLUSIONS: Although intestinal angina is generally defined by severe stenosis of at least two vessels among the celiac and mesenteric arteries, the present case suggests that hemodynamic changes can greatly affect intestinal perfusion and induce intestinal angina in the presence of mild stenosis of the celiac and mesenteric arteries.

PMID- 27686382 TI - Efficient evaluation of cellulose digestibility by Trichoderma reesei Rut-C30 cultures in online monitored shake flasks. AB - BACKGROUND: Pretreated lignocellulosic biomass is considered as a suitable feedstock for the sustainable production of chemicals. However, the recalcitrant nature of cellulose often results in very cost-intensive overall production processes. A promising concept to reduce the costs is consolidated bioprocessing, which integrates in a single step cellulase production, cellulose hydrolysis, and fermentative conversion of produced sugars into a valuable product. This approach, however, requires assessing the digestibility of the applied celluloses and, thus, the released sugar amount during the fermentation. Since the released sugars are completely taken up by Trichoderma reesei Rut-C30 and the sugar consumption is stoichiometrically coupled to oxygen uptake, the respiration activity was measured to evaluate the digestibility of cellulose. RESULTS: The method was successfully tested on commercial cellulosic substrates identifying a correlation between the respiration activity and the crystallinity of the substrate. Pulse experiments with cellulose and cellulases suggested that the respiration activity of T. reesei on cellulose can be divided into two distinct phases, one limited by enzyme activity and one by cellulose-binding-sites. The impact of known (cellobiose, sophorose, urea, tween 80, peptone) and new (miscanthus steepwater) compounds enhancing cellulase production was evaluated. Furthermore, the influence of two different pretreatment methods, the OrganoCat and OrganoSolv process, on the digestibility of beech wood saw dust was tested. CONCLUSIONS: The introduced method allows an online evaluation of cellulose digestibility in complex and non-complex cultivation media. As the measurements are performed under fermentation conditions, it is a valuable tool to test different types of cellulose for consolidated bioprocessing applications. Furthermore, the method can be applied to identify new compounds, which influence cellulase production. PMID- 27686386 TI - Bacterial pathogens and endosymbionts in ticks. AB - Ticks collected from goats in northern Greece were tested for the presence of tick-borne bacteria. Among adult ticks, 37 (57.8%) were Rhipicephalus bursa, 11 (17.2%) Dermacentor marginatus, 10 (15.6%) Ixodes ricinus, 3 (4.7%) Rhipicephalus sanguineus sensu lato and 2 (3.1%) Haemaphysalis parva; one (1.6%) Rhipicephalus spp. tick was nymph. Rickettsia monacensis, Rickettsia massilae, Anaplasma phagocytophilum and Anaplasma platys were detected in I. ricinus and Rh. bursa ticks. A variety of Coxiella-like endosymbionts were detected in all tick genera tested, forming distinct clades from Coxiella burnetii in the phylogenetic tree based on the 16S rRNA gene. An additional endosymbiont, Candidatus Midichloria mitochondrii, was detected in most of the I. ricinus ticks. Surveillance for human pathogens in ticks provides knowledge helpful for the public health, while further studies are needed to determine the role of endosymbionts in tick physiology, vector competence and probably in public health. PMID- 27686387 TI - High sensitivity of embryo-larval stage of the Mediterranean mussel, Mytilus galloprovincialis to metal pollution in combination with temperature increase. AB - The present work aimed to assess the effects of two widespread metallic pollutants, copper and silver, along with environmentally-realistic temperature increases, on embryo-larval development of the Mediterranean mussel Mytilus galloprovincialis. First, mussel embryos upon fertilization were exposed for 48 h to increasing concentrations of Cu (0.5-500 MUg/L) and Ag (0.1-100 MUg/L) at different temperatures (18, 20, 22 or 24 degrees C) in order to characterize toxicity of each toxicant at the different tested temperatures. Increasing concentrations of a Cu-Ag mixture were then tested in order to assess the mixture effect at different temperatures (18, 20 or 22 degrees C). Embryotoxicity was measured after 48 h of exposure (D-larvae stage) considering both the percentage of abnormalities and developmental arrest in D-larvae. The results suggest that the optimum temperature for mussel larvae development is 18 degrees C (12.65+/- 1.6% malformations) and beyond 20 degrees C a steep increase of abnormal larvae was observed up to 100% at 24 degrees C. Ag was more toxic than Cu with a 50% effective concentration (EC50) at 18 degrees C of 6.58 MUg/L and 17.6 MUg/L, respectively. Temperature increased the toxicity of both metals as proved with the EC50 at 20 degrees C at 3.86 MUg/L and 16.28 MUg/L for Ag and Cu respectively. Toxic unit calculation suggests additive effects of Cu and Ag in mixture at 18 and 20 degrees C. These results highlight a possible impairment of M. galloprovincialis reproduction in the Mediterranean Sea in relation to increase of both pollutants and water temperature due to global warming. PMID- 27686388 TI - Aggregation of European storm-petrel (Hydrobates pelagicus ssp. melitensis) around cage fish farms. Do they benefit from the farms resources? AB - Cage aquaculture aggregates wild fauna due to food provision. Several seabirds frequent fish farms, including the European storm-petrel (Hydrobates pelagicus melitensis). This work investigates the presence of storm-petrels around two aquaculture areas interspersed between breeding colonies in western Mediterranean Sea. Contribution of aquaculture-derived resources to their diet was assessed. Storm-petrels were mist-netted at the colonies and marked by bleaching feathers. Density around aquaculture areas was estimated through visual counts. Marks recognition was conducted visually and by photo-capture. Storm-petrel regurgitates were used as target tissue to estimate diet sources contribution. Contribution of surface zooplankton, ichthyoplankton and aquaculture wastes was estimated through Bayesian mixing modelling combining carbon and nitrogen stable isotopes and fatty acids as biomarkers. Storm-petrel density was high in open-sea aquaculture area, but not observed around near shore farms. Temporal variability of storm-petrels density during the breeding season was linked to their reproductive phenology. Within the open-sea aquaculture area, bluefin tuna farm was more attractive for storm-petrels than seabream/seabass farms. Visual identification of bleaching marks was not useful. Photo-capture showed that 8.3% of the storm-petrels watched around farms were firstly trapped in some of the nearby colonies, and 91.7% were unmarked. Qualitative evidence of aquaculture derived wastes utilization was obtained. However, its estimated contribution was low (4.3%) when compared to ichthyoplankton (61.1%) or zooplankton (34.6%). The studied open-sea farms significantly aggregated storm-petrels along their entire breeding season. Storm-petrels got a slight profit from aquaculture resources. Nevertheless, some concerns arise regarding the cost/benefit balance of the interaction. PMID- 27686389 TI - Future aquafeeds may compromise reproductive fitness in a marine invertebrate. AB - Aquaculture of higher trophic level species is increasingly dependent on the use of terrestrial oil products. The input of terrestrially derived n-6 polyunsaturated fatty acids (PUFA) into marine environments has subsequently increased, with unknown consequences for recipient species. We exposed a sea urchin, Heliocidaris erythrogramma to three experimental diets for 78 days: a high n-3 PUFA marine imitation treatment, a high n-6 PUFA "future aquafeed" treatment and an intermediate "current aquafeed" treatment. Female urchins fed the high n-6 PUFA diet produced larvae with lower survival rates than all other treatments. Males fed the high n-6 PUFA diet produced no viable sperm. Fatty acid composition in reproductive material revealed comprehensive biosynthetic and dietary sparing capabilities in H. erythrogramma. Despite this, the ratio of n-6 PUFA to n-3 PUFA in reproductive tissue increased significantly with diet. We suggest alterations to this ratio is the likely mechanism of negative impact on larval development. PMID- 27686390 TI - Decision Activity in Parietal Cortex - Leader or Follower? AB - Katz and colleagues demonstrate that inactivating the primate lateral intraparietal area (LIP) spares visual motion decisions, even though these same decisions strongly modulate LIP neurons. This work is the latest addition to an intense effort spanning sensory modalities, animals, and techniques to understand which structures comprise the circuits responsible for interpreting sensory signals to make decisions. PMID- 27686392 TI - [Acute bacterial gastroenteritis: 729 cases recruited by a Primary Care national network]. AB - OBJECTIVE: To determine the main clinical and epidemiological features of bacterial gastroenteritis in our environment. PATIENTS AND METHODS: An observational study of a Spanish population in 17 Autonomous Communities. Questionnaires of children with a stool positive culture to bacteria were collected over a one year period. A bivariate analysis was performed on the variables involved, as well as two multivariate models (for antibiotic treatment variables, and comparison Campylobacter/Salmonella). RESULTS: A total of 729 bacterial gastroenteritis episodes were recorded in the 17 Spanish autonomous regions, of which 41.2% were girls and 58.8% boys. The median age was 3.41 years old (interquartile range 1.55 to 6.72). The bacteria isolated were 59.9% Campylobacter, 31.8% non-Typhi Salmonella, 2.7% Aeromonas, 2.4% Yersinia, and 1.5% had more than one strain. Most infections (70%) were direct contacts, and food poisoning was less probable (25.9%). Salmonella is significantly less frequent than Campylobacter in children under the age of 3 years (adjusted OR 0.61; 95%CI: 0.43 to 0.86; P=.005), and Campylobacter is more frequent in rural areas (adjusted OR 1.48; 95%CI: 1.07 to 2.07; P=.012). Antibiotic was prescribed in 33.2% of cases. There was a greater significant difference if stools contained blood or mucus (adjusted OR 1.53; 95%CI: 1.04 to 2.27; P=.031), if the symptoms lasted more than 7days (adjusted OR 2.81; 95%CI: 2.01 to 3.93; P<.000), or if the child was admitted to hospital (adjusted OR 1.95; 95%CI: 1.08 to 3.52; P=.027). CONCLUSIONS: The aetiology of bacterial diarrhoea in paediatrics is typical of that of a developed country. The transmission mechanism is mainly direct, and more cases than appropriate are treated with antibiotics. PMID- 27686391 TI - Keratinocyte-Derived Chemokines Orchestrate T-Cell Positioning in the Epidermis during Vitiligo and May Serve as Biomarkers of Disease. AB - Vitiligo is an autoimmune disease of the skin that results in the destruction of melanocytes and the clinical appearance of white spots. Disease pathogenesis depends on IFN-gamma and IFN-gamma-induced chemokines to promote T-cell recruitment to the epidermis where melanocytes reside. The skin is a complex organ, with a variety of resident cell types. We sought to better define the microenvironment and distinct cellular contributions during autoimmunity in vitiligo, and we found that the epidermis is a chemokine-high niche in both a mouse model and human vitiligo. Analysis of chemokine expression in mouse skin showed that CXCL9 and CXCL10 expression strongly correlate with disease activity, whereas CXCL10 alone correlates with severity, supporting them as potential biomarkers for following disease progression. Further studies in both our mouse model and human patients showed that keratinocytes were the major chemokine producers throughout the course of disease, and functional studies using a conditional signal transducer and activator of transcription (STAT)-1 knockout mouse showed that IFN-gamma signaling in keratinocytes was critical for disease progression and proper autoreactive T-cell homing to the epidermis. In contrast, epidermal immune cell populations including endogenous T cells, Langerhans cells, and gammadelta T cells were not required. These results have important clinical implications, because topical therapies that target IFN-gamma signaling in keratinocytes could be safe and effective new treatments, and skin expression of these chemokines could be used to monitor disease activity and treatment responses.

PMID- 27686394 TI - Indole modifies the central carbon flux in the anaerobic metabolism of Escherichia coli: application to the production of hydrogen and other metabolites. AB - Indole is a bicyclic signaling molecule with effects on both eukaryotic and prokaryotic cells. The majority of studies of indole action have been performed with bacteria cultured under aerobic conditions and little information is available about its effects under anaerobic conditions. Here the effect of the indole on anaerobic metabolism of Escherichia coli WDHL was studied. Indole in the range 0.5-8mM was added to the culture medium and cell growth, hydrogen and metabolite production were compared to cultures lacking indole. Results showed that while 8mM indole abolished growth completely, 4mM indole had a partial bacteriostatic effect and the maximum optical density of the culture decreased by 44% compared to the control cultures. In addition, 4mM indole had an important effect on anaerobic metabolism. Hydrogen production increased from 650+/-115 to 1137+/-343mL H2/L, and hydrogen yield increased from 0.45+/-0.1 to 0.94+/-0.34mol H2/mol glucose, compared to the control culture. Carbon flux was also affected and the composition of the final by-products changed. Lactate (41mM) was the main metabolite in the control cultures, whereas ethanol (56.2mM) and acetate (41.2mM) were the main metabolites in the cultures with 2mM indole. We conclude that the supplementation of E. coli cultures with exogenous indole is a simple and novel strategy to improve the production of hydrogen as well as other metabolites such as ethanol used as biofuels. PMID- 27686395 TI - Plant-assisted bioremediation of a historically PCB and heavy metal-contaminated area in Southern Italy. AB - A plant-assisted bioremediation strategy was applied in an area located in Southern Italy, close to the city of Taranto, historically contaminated by polychlorinated biphenyls (PCBs) and heavy metals. A specific poplar clone (Monviso) was selected for its ability to promote organic pollutant degradation in the rhizosphere, as demonstrated elsewhere. Chemical and microbiological analyses were performed at the time of poplar planting in selected plots at different distances from the trunk (0.25-1m) and at different soil depths (0-20 and 20-40cm), at day 420. A significant decrease in PCB congeners and a reduction in all heavy metals was observed where the poplar trees were present. No evidence of PCB and heavy metal reduction was observed in the non poplar-vegetated soil. Microbial analyses (dehydrogenase activity, cell viability, microbial abundance) of the autochthonous microbial community showed an improvement in soil quality. In particular, microbial activity generally increased in the poplar-rhizosphere and a positive effect was observed in some cases at up to 1m distance from the trunk and up to 40cm depth. The Monviso clone was effective in promoting both a general decrease in contaminant occurrence and an increase in microbial activity in the chronically polluted area a little more than one year after planting. PMID- 27686396 TI - de Quervain's thyroiditis: A review of experience with surgery. AB - BACKGROUND: de Quervain's thyroiditis is an inflammatory condition of the thyroid mostly treated medically, rarely requiring surgical treatment. We intend to review the surgical experience with de Quervain's thyroiditis at a tertiary cancer center over a period of 22years. METHODS: A retrospective review of medical records from 1992 to 2014 at a tertiary cancer center was performed and all patients with a histopathological diagnosis of de Quervain's thyroiditis were included. RESULTS: Ten patients with a histopathological diagnosis of de Quervain's thyroiditis were included in the study. One patient in the study presented with dysphagia due to the goiter. The remaining patients presented with thyroid nodules. None presented with typical symptoms of the disease. Seven of the ten patients that had been evaluated for a goiter at an outside facility underwent fine needle aspiration cytology. Of the seven patients, one patient was suspected to have medullary carcinoma of the thyroid, two had follicular neoplasia, and the others had indeterminate nodules. Eight of the ten patients underwent surgery for suspected malignancy, with eight receiving a total thyroidectomy and two patients getting a thyroid lobectomy with isthmusectomy. Two patients had an abnormally hard gland to palpate during surgery with the others not having any suspicious findings. Seven of the ten of the patients had lymph node sampling from level 6 and all were benign on final pathology. The mean duration of post-operative follow-up was 15months. There was no morbidity associated with surgery in any of these patients with eight of the ten patients requiring thyroid hormone replacement. None of the patients needed further neck surgery for thyroid disease. CONCLUSION: de Quervain's thyroiditis is an inflammatory condition of the thyroid that is rarely treated surgically. However when presentation is atypical and the FNAC is inconclusive or is suspicious for a malignancy, patients receive surgery putting them at a risk for morbidity. Good clinical assessment with combined use of ultrasound with FNAC especially read by an experienced cytopathologist has the potential to reduce unnecessary operative intervention.

AB - Nanotechnology has gained much attention over the last decades, as it offers unique opportunities for the advancement of the next generation of sensing tools. Point-of-care (POC) devices for the selective detection of biomolecules using engineered nanoparticles have become a main research thrust in the diagnostic field. This review presents an overview on how the POC-associated nanotechnology, currently applied for the identification of nucleic acids, proteins and antibodies, might be further exploited for the detection of infectious pathogens: although still premature, future integrations of nanoparticles with biological markers that target specific microorganisms will enable timely therapeutic intervention against life-threatening infectious diseases. PMID- 27686398 TI - Transjugular Access for Endovascular Treatment of Immature Autogenous Arteriovenous Fistulae. AB - PURPOSE: To assess the feasibility and outcome of transjugular access for endovascular treatment of immature arteriovenous fistulae (AVFs). MATERIALS AND METHODS: Between August 2013 and January 2016, 90 patients (mean age, 64.5 y +/- 12.8) underwent endovascular treatment of immature AVFs via transjugular access. The mean age of fistulae was 3.3 months +/- 1.8. Total procedure time and technical and clinical success rates of endovascular procedures were assessed. Primary and secondary patency rates were calculated according to the Kaplan-Meier method, and complications were assessed. RESULTS: All patients had inflow lesions, among which 19 (21.1%) had occlusions. The juxtaanastomotic segment was the most common site (44.3%). Transjugular access was successful in 83 patients (92.2%), and 7 required additional standard or transarterial access. The mean procedure time was 36.5 minutes. Technical and clinical success rates were 98.9% and 90.5%, respectively. Mean primary and secondary patency durations were 14.3 months +/- 1.7 and 31.0 months +/- 0.7, respectively. Primary patency rates at 3, 6, and 12 months were 84.4%, 67.3%, and 48.8%, respectively. Secondary patency rates at 6 and 18 months were 98.6% and 95.5%, respectively. Venous rupture occurred as a result of balloon inflation in 9 patients (10%), and was managed by balloon tamponade. There were no complications related to transjugular access during a mean follow-up period of 12.6 months. CONCLUSIONS: Transjugular access for angioplasty of immature AVFs is feasible and safe. Potential problems associated with access in the outflow vein could be avoided by transjugular access. PMID- 27686399 TI - Pharmacokinetic properties, in vitro metabolism and plasma protein binding of govaniadine an alkaloid isolated from Corydalis govaniana Wall. AB - Govaniadine (GOV) is an alkaloid isolated from Corydalis govaniana Wall. It has been reported to show a different number of biological activities including anti urease, leishmanicidal and antinociceptive. The present study aims to characterize the GOV in vitro metabolism after incubation with rat and human liver microsomes (RLM and HLM, respectively) and to evaluate its pharmacokinetic properties. The identification of GOV metabolites was conducted by different mass analyzers: a micrOTOF II-ESI-ToF Bruker Daltonics(r) and an amaZon-SL ion trap (IT) Bruker Daltonics(r). For the pharmacokinetic study of GOV in rats after intravenous administration, a LC-MS/MS method was developed and applied to. The analyses were performed using an Acquity UPLC(r) coupled to an Acquity TQD detector equipped with an ESI interface. The liver microsomal incubation resulted in new O-demethylated, di-hydroxylated and mono-hydroxylated compounds. Regarding the method validation, the calibration curve was linear over the concentration range of 2.5-3150.0ngmL-1, with a lower limit of quantitation (LLOQ) of 2.5ngmL 1. This method was successfully applied to a pharmacokinetic study. The profile was best fitted to a two-compartment model, the first phase with a high distribution rate constant (alpha) 0.139+/-0.086min-1, reflected by the short distribution half-life (t1/2alpha) 9.2+/-8.9min and the later one, with an elimination half-life (t1/2beta) 55.1+/-37.9min. The main plasma protein binding was 96.1%. This is a first report in this field and it will be useful for further development of govaniadine as a drug candidate. PMID- 27686400 TI - Sculpting the labyrinth: Morphogenesis of the developing inner ear. AB - The vertebrate inner ear is a precision sensory organ, acting as both a microphone to receive sound and an accelerometer to detect gravity and motion. It consists of a series of interlinked, fluid-filled chambers containing patches of sensory epithelia, each with a specialised function. The ear contains many different differentiated cell types with distinct morphologies, from the flask shaped hair cells found in thickened sensory epithelium, to the thin squamous cells that contribute to non-sensory structures, such as the semicircular canal ducts. Nearly all cell types of the inner ear, including the afferent neurons that innervate it, are derived from the otic placode, a region of cranial ectoderm that develops adjacent to the embryonic hindbrain. As the ear develops, the otic epithelia grow, fold, fuse and rearrange to form the complex three dimensional shape of the membranous labyrinth. Much of our current understanding of the processes of inner ear morphogenesis comes from genetic and pharmacological manipulations of the developing ear in mouse, chicken and zebrafish embryos. These traditional approaches are now being supplemented with exciting new techniques-including force measurements and light-sheet microscopy that are helping to elucidate the mechanisms that generate this intricate organ system. PMID- 27686401 TI - Relationships among plasma granzyme B level, pruritus and dermatitis in patients with atopic dermatitis. AB - BACKGROUND: Atopic dermatitis (AD) is a multifactorial inflammatory skin disease characterized by skin barrier dysfunction, allergic inflammation and intractable pruritus resistant to conventional antipruritic treatments, including H1 antihistamines. Granzymes (Gzms) are a family of serine proteases expressed by cytotoxic T lymphocytes and natural killer cells that have been shown to modulate inflammation. However, the relationship between Gzms and pathology in AD remains unclear. OBJECTIVE: This study assessed the correlation between plasma GzmB levels and severity of pruritus and dermatitis, in AD patients. METHODS: Plasma was collected from 46 patients with AD, 24 patients with psoriasis, and 30 healthy controls. AD severity was assessed with the scoring atopic dermatitis (SCORAD) index, psoriasis severity with the psoriasis area and severity index (PASI), and degree of pruritus by visual analogue scale (VAS) score. GzmA, GzmB and gastrin releasing peptide (GRP) levels were measured by enzyme-linked immunosorbent assays. RESULTS: Plasma GzmB concentrations were significantly higher in patients with AD and psoriasis than in healthy controls. Correlation analyses showed that plasma GzmB concentrations positively correlated with SCORAD and serum levels of severity markers such as thymus and activation-regulated chemokine, and lactate dehydrogenase in AD patients. Moreover, plasma levels of GRP, an itch-related peptide, were higher in patients with AD, positively correlating with VAS score and plasma GzmB level. In addition, plasma GzmB concentration was significantly lower in the treatment group than the untreated group with AD. Meanwhile, there were no correlations among GzmB levels, VAS score and PASI score in patients with psoriasis. In contrast to the results of plasma GzmB, plasma GzmA levels were unchanged among AD, psoriasis and healthy groups, and showed no correlations with VAS score and SCORAD index in patients with AD. CONCLUSION: Plasma GzmB levels may reflect the degree of pruritus and dermatitis in patients with AD. PMID- 27686402 TI - Exercise promotes IL-6 release from legs in older men with minor response to unilateral immobilization. AB - Physical inactivity is a major contributor to low-grade systemic inflammation. Most of the studies characterizing interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) release from exercising legs have been done in young, healthy men, but studies on inactivity in older people are lacking. The impact of 14 days of one-leg immobilization (IM) on IL-6 and TNF-alpha release during exercise in comparison to the contralateral control (CON) leg was investigated. Fifteen healthy men (age 68.1 +/- 1.1 year (mean +/- SEM); BMI 27.0 +/- 0.4 kg.m(2); VO2max 33.3 +/- 1.6 ml.kg(-1).min(-1)) performed 45 min of two-leg dynamic knee extensor exercise at 19.5 +/- 0.9 W. Arterial and femoral venous blood samples from the CON and the IM legs were collected every 15 min during exercise, and thigh blood flow was measured with ultrasound Doppler. Arterial plasma IL-6 concentration increased with exercise (rest vs. 45 min, main effect p < .05). IL-6 release increased with exercise (rest vs. 30 min, main effect p < .05). Furthermore, IL-6 release was borderline (main effect, p = .085, effect size 0.28) higher in the IM leg compared to the CON leg (288 (95% CI: 213-373) vs. 220 (95% CI: 152-299) pg.min(-1), respectively). There was no release of TNF alpha in either leg and arterial concentrations remained unchanged during exercise (p > .05). In conclusion, exercise induces more pronounced IL-6 secretion in healthy older men. Two weeks of unilateral immobilization on the other hand had only a minor influence on IL-6 release. Neither immobilization nor exercise had an effect on TNF-alpha release across the working legs in older men. PMID- 27686403 TI - Influence of a caffeine mouth rinse on sprint cycling following glycogen depletion. AB - Attenuated performance during intense exercise with limited endogenous carbohydrate (CHO) is well documented. Therefore, this study examined whether caffeine (CAF) mouth rinsing would augment performance during repeated sprint cycling in participants with reduced endogenous CHO. Eight recreationally active males (aged 23 +/- 2 yr, body mass 84 +/- 4 kg, stature 178 +/- 7 cm) participated in this randomized, single-blind, repeated-measures crossover investigation. Following familiarization, participants attended two separate evening glycogen depletion sessions. The following morning, participants completed five, 6 s sprints on a cycle ergometer (separated by 24 s active recovery), with mouth rinsing either (1) a placebo solution or (2) a 2% CAF solution. During a fifth visit, participants completed the sprints without prior glycogen depletion. Repeated-measures ANOVA identified significant main effect of condition (CAF, placebo, and control [P < .05; effect size (ES) = 0.850-0.897]), sprint (1-5 [P < .005; ES = 0.871-0.986]), and interaction (condition * sprint [P < .05; ES = 0.831-0.846]), for peak and mean power. The control condition exhibited the highest peak power (overall mean 760 +/- 77 W) and mean power (overall mean 699 +/- 83W) over the five sprints (P < .001 in both instances). CAF peak power (overall mean 643 +/- 79 W) was significantly greater than placebo (mean 573 +/- 79 W [P < .05; ES = 0.850]). Additionally, CAF mean power (overall mean 589 +/- 80 W) was significantly greater than placebo (519 +/- 82 W [P < .05; ES = 0.397]). These data indicate that mouth rinsing a caffeinated solution reduces decrements caused by CHO reduction, which may benefit athletes wishing to train in a low-CHO state. PMID- 27686404 TI - Evaluation of the performance of high temperature conversion reactors for compound-specific oxygen stable isotope analysis. AB - In this study conversion conditions for oxygen gas chromatography high temperature conversion (HTC) isotope ratio mass spectrometry (IRMS) are characterised using qualitative mass spectrometry (IonTrap). It is shown that physical and chemical properties of a given reactor design impact HTC and thus the ability to accurately measure oxygen isotope ratios. Commercially available and custom-built tube-in-tube reactors were used to elucidate (i) by-product formation (carbon dioxide, water, small organic molecules), (ii) 2nd sources of oxygen (leakage, metal oxides, ceramic material), and (iii) required reactor conditions (conditioning, reduction, stability). The suitability of the available HTC approach for compound-specific isotope analysis of oxygen in volatile organic molecules like methyl tert-butyl ether is assessed. Main problems impeding accurate analysis are non-quantitative HTC and significant carbon dioxide by product formation. An evaluation strategy combining mass spectrometric analysis of HTC products and IRMS 18O/16O monitoring for future method development is proposed.

PMID- 27686407 TI - Discovery and characterization of miRNAs in mouse thymus responses to ionizing radiation by deep sequencing. AB - To investigate the potential regulatory roles of microRNA (miRNA) in mouse response to ionizing radiation (IR)-induced thymus injury, miRNA expression profiles of mouse thymus with or without IR were analyzed using deep sequencing technology. Potential target candidates of the identified miRNA were predicted using RNAhybrid and miRanda. Differently expressed miRNA targets functional annotation and pathways were noted using Swiss-Prot, Gene Ontology (GO), Clusters of Orthologous Groups (COG), Kyoto Encyclopedia of Genes and Genomes (KEGG) and non-redundant (NR) databases. In this study, there were 112 differently expressed miRNAs identified, including 45 known mature and 67 novel miRNAs, which meanwhile contained 77 up-regulated and 35 down-regulated miRNAs. The results of quantitative RT-polymerase chain reaction (qRT-PCR) verification were in agreement with the sequencing analysis. And the target genes of miRNA were annotated. These results revealed the differences of miRNA expression, further extended the biological knowledge and greatly facilitated future studies on the function of miRNA in IR-induced thymus injury. PMID- 27686406 TI - Inhibitory mechanism of peptides with a repeating hydrophobic and hydrophilic residue pattern on interleukin-10. AB - Interleukin 10 (IL-10) is a cytokine that is able to downregulate inflammation. Its overexpression is directly associated with the difficulty in the clearance of chronic viral infections, such as chronic hepatitis B, hepatitis C and HIV infection, and infection-related cancer. IL-10 signaling blockade has been proposed as a promising way of clearing chronic viral infection and preventing tumor growth in animal models. Recently, we have reported that peptides with a helical repeating pattern of hydrophobic and hydrophilic residues are able to inhibit IL-10 significantly both in vitro and in vivo. 1 In this work, we seek to further study the inhibiting mechanism of these peptides using sequence-modified peptides. As evidenced by both experimental and molecular dynamics simulation in concert the N-terminal hydrophobic peptide constructed with repeating hydrophobic and hydrophilic pattern of residues is more likely to inhibit IL10. In addition, the sequence length and the ability of protonation are also important for inhibition activity. PMID- 27686408 TI - Impact of T-cell-specific Smad4 deficiency on the development of autoimmune diabetes in NOD mice. AB - Type 1 diabetes results from autoimmune-mediated pancreatic beta-cell destruction and transforming growth factor-beta (TGF-beta) is known to play a preventive role in type 1 diabetes in non-obese diabetic (NOD) mice. In this study, we investigated the role of Smad4, a key molecule for Smad-dependent TGF-beta signaling, in T cells of NOD mice in the pathogenesis of autoimmune diabetes. We generated T-cell-specific Smad4 knockout (Smad4 tKO) NOD mice and assessed the pathological and immunological changes. Smad4 tKO showed earlier onset and increased incidence of diabetes than wild type (WT) NOD mice. Pathological features such as insulitis, anti-glutamic acid decarboxylase auto-antibody levels and serum IFN-gamma levels were significantly increased in Smad4 tKO compared with WT NOD mice. Proportion and number of activated/memory CD4+ T cell were significantly increased in pancreatic lymph nodes of Smad4 tKO compared with WT NOD mice. However, the proportion and function of regulatory T cells was not different. Effector CD4+ T cells from Smad4 tKO were more resistant to suppression by regulatory T cells than effector cells from WT NOD mice. The proliferative potential of effector T cells from Smad4 tKO was significantly elevated compared with WT NOD mice, and activation of sterol regulatory element binding protein-1c (SREBP-1c) in T cells of Smad4 tKO NOD mice was correlated with this proliferative activity. We conclude that Smad4 deletion in T cells of NOD mice accelerated the development of autoimmune diabetes and increased the incidence of the disease by dysregulation of T cell activation at least in part via SREBP-1c activation. PMID- 27686409 TI - Single-molecule visualization of dynamic transitions of pore-forming peptides among multiple transmembrane positions. AB - Research on the dynamics of single-membrane proteins remains underdeveloped due to the lack of proper approaches that can probe in real time the protein's insertion depth in lipid bilayers. Here we report a single-molecule visualization method to track both vertical insertion and lateral diffusion of membrane proteins in supported lipid bilayers by exploiting the surface-induced fluorescence attenuation (SIFA) of fluorophores. The attenuation follows a d-4 dependency, where d is the fluorophore-to-surface distance. The method is validated by observing the antimicrobial peptide LL-37 to transfer among five transmembrane positions: the surface, the upper leaflet, the centre, the lower leaflet and the bottom of the lipid bilayer. These results demonstrate the power of SIFA to study protein-membrane interactions and provide unprecedented in-depth understanding of molecular mechanisms of the insertion and translocation of membrane proteins. PMID- 27686410 TI - Treating epileptic emergencies - pharmacological advances. AB - INTRODUCTION: Epileptic emergencies are frequently encountered and include ictal events as status epilepticus or seizure clusters, and non-ictal situations like postictal psychosis or acute drug side effects. The aim of this review was to describe recent pharmacological advances in the treatment of epileptic emergencies. Areas covered: Based on clinically relevant questions, a literature search was performed. The search showed that most pharmacological advances have been made in management of status epilepticus, where substantial literature has accumulated on several AEDs with potentially less side-effects than the traditional choices. The use of these drugs; valproate, levetiracetam, and lacosamide, was therefore made the main focus of this review. Pharmacological advances in treatment of other epileptic emergencies were scarce, and were therefore covered more briefly in the Expert Opinion section. Expert opinion: This section outlines our current practice in management of status epilepticus and seizures clusters. Our opinion is that valproate is an equal alternative as second line treatment to fosphenytoin, with levetiracetam considered a good choice in frail and elderly patients. Due to the lack of literature, lacosamide is used mainly as a 2nd line drug after the failure of valproate, fosphenytoin and levetiracetam. Our review underlines the need for more research in management of epileptic emergencies. PMID- 27686411 TI - Management of a Patient With Acute Acetabular Labral Tear and Femoral Acetabular Impingement With Intra-articular Steroid Injection and a Neuromotor Training Program. AB - Study Design Case report. Background Intra-articular hip pathologies can be difficult to diagnose, and evidence to guide physical therapy interventions is lacking. The purpose of this case report is to describe a clinical pathway for conservative management of a patient with an acute acetabular labral tear and femoroacetabular impingement. Case Description The patient was an 18-year-old woman with recent onset of right groin pain who underwent intra-articular corticosteroid injection and therapeutic exercise for the management of an acute acetabular labral tear identified on radiographic imaging. Prior to physical therapy, the patient received an intra-articular hip injection for diagnostic purposes and pain relief. Upon initial evaluation, the patient presented with improved pain but with continued kinesthetic deficits, inflexibility, muscle imbalances, and reproduction of symptoms with end-range hip motions. A physical therapy plan was implemented using neuromuscular re-education to address her continued impairments. Outcomes Marked improvements were noted at discharge and 6 month follow-up for pain, strength, and function as demonstrated on the Patient Specific Functional Scale, global rating of change scale, and International Hip Outcome Tool-33. Discussion This case demonstrates a clinical pathway for collaborative medical management of a patient with confirmed intra-articular pathology. Details illustrate the clinical reasoning and rationale used to guide the clinical decision-making process. Level of Evidence Therapy, level 4. J Orthop Sports Phys Ther 2016;46(11):965-975.

AB - Study Design Controlled laboratory study. Background Altered hip and knee kinematics have been associated with several knee disorders, including anterior cruciate ligament tear, patellofemoral pain, and iliotibial band syndrome. Limited ankle dorsiflexion (DF) range of motion (ROM), which has been linked with some of these disorders, has also been associated with altered knee kinematics. Objective To explore the association of ankle DF ROM with hip and knee kinematics during a step-down task. Methods Thirty healthy participants underwent a 3-D analysis of hip and knee kinematics during a lateral step-down test, followed by measurement of ankle DF ROM in weight bearing (WB) and non-weight bearing (NWB). Participants were dichotomized using the median values into low- and high-DF subgroups within both WB and NWB. Hip and knee kinematics were compared between the low- and high-DF subgroups. Results Participants in the low-DF subgroups exhibited greater peak hip adduction (WB, P = .02; NWB, P<.01) and greater peak knee external rotation (WB, P = .02; NWB, P<.01) compared with participants in the high-DF subgroups. In addition, participants in the low-DF WB subgroup exhibited decreased peak knee flexion compared with participants in the high-DF WB subgroup (P<.01). Conclusion Individuals with lower ankle DF ROM exhibited hip and knee kinematics previously associated with several knee disorders, suggesting that this impairment may be involved in the pathogenesis of the same disorders. Assessment of ankle DF ROM may be useful as part of a preparticipation screening. Furthermore, deficits in ankle DF ROM may need to be addressed in individuals with altered movement patterns.

PMID- 27686413 TI - Pelvic Rotation in Femoroacetabular Impingement Is Decreased Compared to Other Symptomatic Hip Conditions. AB - Study Design Cross-sectional, case-control design. Background Pelvic movement has been considered a possible discriminating parameter associated with femoroacetabular impingement (FAI) symptom onset. Decreased pelvic rotation has been found during squatting in people with FAI when compared to people with healthy hips. However, it is possible that changes in pelvic movement may occur in other hip conditions because of pain and may not be specific to FAI. Objectives To compare sagittal pelvic rotation during hip flexion and in sitting between people with FAI and people with other symptomatic hip conditions. Methods Thirty people with symptomatic FAI, 30 people with other symptomatic hip conditions, and 20 people with healthy hips participated in the study. Sagittal pelvic rotation was calculated based on measures of pelvic alignment in standing, hip flexion to 45 degrees and 90 degrees , and sitting. Results There were significant differences in sagittal pelvic rotation among the 3 groups in all conditions (P<.05). Post hoc analyses revealed that participants in the symptomatic FAI group had less pelvic rotation during hip flexion to 45 degrees and 90 degrees compared to participants in the other symptomatic hip conditions group and the hip-healthy group (mean difference, 1.2 degrees -1.9 degrees ). In sitting, participants in the other symptomatic hip conditions group had less posterior pelvic rotation compared to those in the hip-healthy group (mean difference, 3.9 degrees ). Conclusion People with symptomatic FAI have less posterior pelvic rotation during hip flexion when compared to people with other symptomatic hip conditions and those with healthy hips.

AB - OBJECTIVES: To develop an electromagnetic navigation technology for transjugular intrahepatic portosystemic shunt (TIPS) creation and translate it from phantom to an in-vivo large animal setting. MATERIAL AND METHODS: A custom-designed device for TIPS creation consisting of a stylet within a 5 French catheter as well as a software prototype were developed that allow real-time tip tracking of both stylet and catheter using an electromagnetic tracking system. Feasibility of navigated TIPSS creation was tested in a phantom by two interventional radiologists (A/B) followed by in-vivo testing evaluation in eight domestic pigs. Procedure duration and number of attempts needed for puncture of the portal vein were recorded. RESULTS: In the phantom setting, intervention time to gain access to the portal vein (PV) was 144 +/- 67 s (A) and 122 +/- 51 s (B), respectively. In the in-vivo trials, TIPS could be successfully completed in five out of eight animals. Mean time for the complete TIPS was 245 +/- 205 minutes with a notable learning curve towards the last animal. CONCLUSIONS: TIPS creation with the use of electromagnetic tracking technology proved to be feasible in-vitro as well as in-vivo. The system may be useful to facilitate challenging TIPSS procedures.

AB - Gut colonization with enterotoxigenic Bacteroides fragilis (ETBF) appears to be associated with the development of colorectal cancer. However, differences in carriage rates are seen with various testing methods and sampling sites. We compared standard PCR, SYBR green and TaqMan quantitative PCR (qPCR) and digital PCR (dPCR) in detecting the B. fragilis toxin (bft) gene from cultured ETBF, and from matched luminal and faecal stool samples from 19 colorectal cancer patients. Bland-Altman analysis found that all three quantitative methods performed comparably in detecting bft from purified bacterial DNA, with the same limits of detection (<1 copy/MUl). However, SYBR qPCR under-performed compared to TaqMan qPCR and dPCR in detecting bft in clinical stool samples; 13/38 samples were reported positive by SYBR, compared to 35 and 36 samples by TaqMan and dPCR, respectively. TaqMan qPCR and dPCR gave bft copy numbers that were 48-fold and 75 fold higher for the same samples than SYBR qPCR, respectively (p < 0.001). For samples that were bft-positive in both fecal and luminal stools, there was no difference in relative abundance between the sites, by any method tested. From our findings, we recommend the use of TaqMan qPCR as the preferred method to detect ETBF from clinical stool samples. PMID- 27686416 TI - Allochthonous carbon is a major regulator to bacterial growth and community composition in subarctic freshwaters. AB - In the subarctic region, climate warming and permafrost thaw are leading to emergence of ponds and to an increase in mobility of catchment carbon. As carbon of terrestrial origin is increasing in subarctic freshwaters the resource pool supporting their microbial communities and metabolism is changing, with consequences to overall aquatic productivity. By sampling different subarctic water bodies for a one complete year we show how terrestrial and algal carbon compounds vary in a range of freshwaters and how differential organic carbon quality is linked to bacterial metabolism and community composition. We show that terrestrial drainage and associated nutrients supported higher bacterial growth in ponds and river mouths that were influenced by fresh terrestrial carbon than in large lakes with carbon from algal production. Bacterial diversity, however, was lower at sites influenced by terrestrial carbon inputs. Bacterial community composition was highly variable among different water bodies and especially influenced by concentrations of dissolved organic carbon (DOC), fulvic acids, proteins and nutrients. Furthermore, a distinct preference was found for terrestrial vs. algal carbon among certain bacterial tribes. The results highlight the contribution of the numerous ponds to cycling of terrestrial carbon in the changing subarctic and arctic regions.

AB - We consider Bayesian estimate of static magnetic field, characterized by a prior Gaussian probability distribution, in systems of a few electron quantum dot spins interacting with infinite temperature spin environment via hyperfine interaction. Sudden transitions among optimal states and measurements are observed. Usefulness of measuring occupation levels is shown for all times of the evolution, together with the role of entanglement in the optimal scenario. For low values of magnetic field, memory effects stemming from the interaction with environment provide limited metrological advantage.

AB - Noise overstimulation can induce loss of synaptic ribbons associated with loss of Inner Hair Cell - Auditory Nerve synaptic connections. This study examined if systemic administration of Piribedil, a dopamine agonist that reduces the sound evoked auditory nerve compound action potential and/or Memantine, an NMDA receptor open channel blocker, would reduce noise-induced loss of Inner Hair Cell ribbons. Rats received systemic Memantine and/or Piribedil for 3 days before and 3 days after a 3 hour 4 kHz octave band noise at 117 dB (SPL). At 21 days following the noise there was a 26% and 38% loss of synaptic ribbons in regions 5.5 and 6.5 mm from apex, respectively, elevations in 4-, 8- and 20 kHz tonal ABR thresholds and reduced dynamic output at higher intensities of stimulation. Combined treatment with Piribedil and Memantine produced a significant reduction in the noise-induced loss of ribbons in both regions and changes in ABR sensitivity and dynamic responsiveness. Piribedil alone gave significant reduction in only the 5.5 mm region and Memantine alone did not reach significance in either region. Results identify treatments that could prevent the hearing loss and hearing disorders that result from noise-induced loss of Inner Hair Cell - Auditory Nerve synaptic connections. PMID- 27686419 TI - High-mechanical-frequency characteristics of optomechanical crystal cavity with coupling waveguide. AB - Optomechanical crystals have attracted great attention recently for their ability to realize strong photon-phonon interaction in cavity optomechanical systems. By far, the operation of cavity optomechanical systems with high mechanical frequency has to employ tapered fibres or one-sided waveguides with circulators to couple the light into and out of the cavities, which hinders their on-chip applications. Here, we demonstrate larger-centre-hole nanobeam structures with on chip transmission-coupling waveguide. The measured mechanical frequency is up to 4.47 GHz, with a high mechanical Q-factor of 1.4 * 103 in the ambient environment. The corresponding optomechanical coupling rate is calculated and measured to be 836 kHz and 1.2 MHz, respectively, while the effective mass is estimated to be 136 fg. With the transmission waveguide coupled structure and a small footprint of 3.4 MUm2, this simple cavity can be directly used as functional components or integrated with other on-chip devices in future practical applications.

AB - Two alkaloids of the furoquinoline-type were isolated from Ammi majus L.; a new one and was identified as 4-hydro-7-hydroxy-8-methoxyfuroquinoline (1), and the other was isolated for the second time from nature and was identified as 4-hydro 7-hydroxy-8-prenyloxyfuroquinoline (2). The structures of the isolated compounds were established and confirmed by 1D and 2D NMR spectroscopy including 1H, 13C NMR, COSY, HSQC and HMBC, while the exact masses were confirmed by HRESI/MS. The cytotoxic activity of the isolated compounds (1 and 2) was evaluated against HepG 2, PC-3, A-549 and MCF-7 and the obtained results suggested selective antiproliferative and cytotoxic effects, with IC50 = 230.2 and 326.5 MUM against HepG-2 and MCF-7, respectively, for compound (1). While, compound (2) recorded IC50 = 234.2 MUM against MCF-7. PMID- 27686421 TI - A Case Study of Engaging Hard-to-Reach Participants in the Research Process: Community Advisors on Research Design and Strategies (CARDS)(r). AB - Lack of diversity among study participants in clinical research limits progress in eliminating health disparities. The engagement of lay stakeholders, such as patient or community advisory boards (CABs), has the potential to increase recruitment and retention of underrepresented groups by providing a structure for gathering feedback on research plans and materials from this target population. However, many CABs intentionally recruit prominent stakeholders who are connected to or comfortable with research and academia and thus may not accurately represent the perspectives of underrepresented groups who have been labeled hard to-reach, including racial minorities and low-income or low-literacy populations. We developed a partnership between the University of Wisconsin-Madison School of Nursing and two community centers to deliberately engage hard-to-reach people in two lay advisory groups, the Community Advisors on Research Design and Strategies (CARDS)(r). Community center staff recruited the CARDS from center programs, including parenting and childcare programs, women's support groups, food pantries, and senior meal programs. The CARDS model differs from other CABs in its participants, processes, and outcomes. Since 2010, the CARDS have met monthly with nurses and other researchers, helping them understand how research processes and the language, tone, appearance, and organization of research materials can discourage people from enrolling in clinical studies. We have successfully used the CARDS model to bring hard-to-reach populations into the research process and have sustained their participation. The model represents a promising strategy for increasing the diversity of participants in clinical research. (c) 2016 Wiley Periodicals, Inc. PMID- 27686422 TI - A trophic framework for animal origins. AB - Metazoans emerged in a microbial world and play a unique role in the biosphere as the only complex multicellular eukaryotes capable of phagocytosis. While the bodyplan and feeding mode of the last common metazoan ancestor remain unresolved, the earliest multicellular stem-metazoans likely subsisted on picoplankton (planktonic microbes 0.2-2 MUm in diameter) and dissolved organic matter (DOM), similarly to modern sponges. Once multicellular stem-metazoans emerged, they conceivably modulated both the local availability of picoplankton, which they preferentially removed from the water column for feeding, and detrital particles 2-100 MUm in diameter, which they expelled and deposited into the benthos as waste products. By influencing the availability of these heterotrophic food sources, the earliest multicellular stem-metazoans would have acted as ecosystem engineers, helping create the ecological conditions under which other metazoans, namely detritivores and non-sponge suspension feeders incapable of subsisting on picoplankton and DOM, could emerge and diversify. This early style of metazoan feeding, specifically the phagocytosis of small eukaryotic prey, could have also encouraged the evolution of larger, even multicellular, eukaryotic forms less prone to metazoan consumption. Therefore, the first multicellular stem-metazoans, through their feeding, arguably helped bridge the strictly microbial food webs of the Proterozoic Eon (2.5-0.541 billion years ago) to the more macroscopic, metazoan-sustaining food webs of the Phanerozoic Eon (0.541-0 billion years ago).

AB - Herein, we report a carbazolyl tubular macrocycle (3), which possesses a "pi tube" capable of encapsulating and sensing bisphenol F (BPF), which is a toxic industrial material. In this work, the synthesis of 3, its conformation in solution as well as its binding property to BPF have been investigated. Nuclear magnetic resonance (NMR), ultraviolet-visible light (UV-vis), fluorescence spectra, and molecular modeling studies reveal that the "pi-tube" of 3 in 1,3 alternate conformation could encapsulate BPF with 1:1 binding stoichiometry in water, with its orthogonal tweezers sandwiching the two phenol units of BPF. Moreover, 3 could serve as a sensitive fluorescent probe for BPF (limitation of detection = 157 nM). PMID- 27686425 TI - Saint Ioannis Lampadistis, the first possible case of blindness due to organic mercury poisoning in history. AB - Saint Ioannis Lampadistis is a Cypriot saint of the Greek Orthodox Church, widely venerated in his island of origin. He lived during the 11th century and was blinded by ingesting contaminated fish in the mountainous area of Galata, withdrew from civil life when he was 18, and died at the age of 22. The reason for his blindness remains unknown, though it is widely attributed to an unknown poison related to the copper mines of the region. As fish is the end reservoir of organic mercury, it is quite possible that his blindness was the result of heavy metal toxicity. Organic mercury is associated with CNS atrophy and hypoplasia, and blindness is a frequent presenting symptom. While not much is known about the saint's clinical symptoms (as his ecclestiastical biography focuses on his example and miracles), organic mercury poisoning could explain his sudden loss of vision, thus possibly making him the first-recorded case of organic mercury poisoning in history.

PMID- 27686428 TI - SAnDReS a Computational Tool for Statistical Analysis of Docking Results and Development of Scoring Functions. AB - BACKGROUND: Docking allows to predict ligand binding to proteins, since the 3D structure for the target is available. Several docking studies have been carried out to identify potential ligands for drug targets. Many of these studies resulted in the leads that were later developed as drugs. OBJECTIVE: Our goal here is to describe the development of an integrated computational tool to assess docking accuracy and build new scoring functions to predict ligandbinding affinity. METHOD: We carried out docking simulations using MVD program for a data set available on CSAR 2014 database (coagulation factor Xa) for which ligand binding information and structures are available. These docking results were analyzed using SAnDReS available at www.sandres.net. Machine learning methods were applied to build new scoring functions and our results were compared with previously published benchmarks. RESULTS: Our integrated docking strategy generated poses with docking accuracy higher than previously published benchmarks. In addition, the new scoring function developed using SAnDReS shows better performance than well-established scoring functions such the ones available in Autodock, Autodock- Vina, Gold, Glide, and MVD. CONCLUSION: The big data generated during docking lacked an integrated computational tool for statistical analysis of the influence of structural parameters on docking and scoring function performance. Here we describe methods to evaluate docking results using SAnDReS, a computational environment for statistical analysis of docking results and development of scoring functions. We believe that SAnDReS is a computational tool with potential to improve accuracy in docking projects.

AB - Objective: To analyze the features of nerve conduction in patients with amyotrophic lateral sclerosis (ALS), and explore the correlation between compound muscle action potential (CMAP) amplitude and disease duration and revised amyotrophic lateral sclerosis functional rating scale (ALSFRS-R). Methods: Standard motor and sensory nerve conduction studies were performed in 154 patients with ALS. The following parameters were collected including CMAP amplitude, distal motor latency (DML), motor conduction velocity, sensory conduction velocity and sensory nerve action potential amplitude. Regression study was done to explore the correlation between CMAP amplitude and disease duration and ALSFRS-R. Results: Motor nerve conduction abnormalities were presented in a majority of the patients with prolonged DML in the tibial nerve, median nerve and ulnar nerve as the most common form (61.06%-81.42%), followed by decreased CMAP amplitude (30.12%-53.98%), decreased MCV (12.05%-16.81%) and absence of CMAP (2.65%-9.73%). Sensory nerve conduction abnormalities were detected in a small proportion of patients and the decreased SCV, decreased SNAP amplitude and absence of SNAP in the sural nerve, median nerve and ulnar nerve were found in 1.22%-2.73%, 0-1.82% and 0-1.22% patients respectively. No correlation was found between CMAP of the common peroneal nerve, tibial nerve, median nerve and ulnar nerve and the disease duration (P>0.05), while significant positive correlation was established between CMAP amplitude of the median nerve and ulnar nerve and ALSFRS-R (r=0.273, P=0.016; r=0.357, P=0.001). Conclusions: Motor nerve conduction is abnormal in a majority of ALS patients with prolonged DML as the most common form, while abnormal sensory nerve conduction is only found in a few of ALS patients. CMAP amplitude of the median nerve and ulnar nerve might be of certain clinical value in evaluating the severity of ALS. PMID- 27686435 TI - [A clinical study of single subcortical cerebral infarction of middle cerebral artery territory]. AB - Objective: To explore the clinical characteristics of single subcortical cerebral infarction of middle cerebral artery (MCA) territory and the possible pathogenesis. Methods: A total of 344 cases diagnosed as single subcortical cerebral infarction of MCA territory were enrolled in the study and divided into the parent artery disease (PAD) group and the non-PAD group according to whether the MCA stenosis was presented or not. A total of 312 cases diagnosed as single subcortical cerebral infarction of MCA territory were divided into the BAD group and the SVD group according to the relationship between the lesion sites and MCA. Differences in the clinical and imaging feature were compared between different groups. Results: A total of 32 patients were in the PAD group. Compared with the non-PAD group, patients in the PAD group were found with higher prevalence of asymptomatic cerebral arterial atherosclerosis [93.8%(30/32) vs 57.1%(178/312), P<0.001], higher prevalence of branch atheromatous disease[75.0%(24/32) vs 58.7%(183/312), P=0.072]. A total of 183 patients were in the BAD group. Compared with the BAD group, patients in the SVD group were older[(64.7+/-11.2) years vs (61.7+/-12.2) years, P=0.031], more with hypertension [65.9%(85/129) vs 53.0%(97/183), P=0.027] and smoking [41.9%(54/129) vs 57.9%(106/183), P=0.006] and more severe leukoaraiosis. Conclusions: Single subcortical cerebral infarction of MCA territory has different etiology and pathogenesis. Evidence of systemic atherosclerosis should be carefully searched in patients with branch atheromatous disease.

AB - Objective: To investigate the efficacy and outcome in newly diagnosed multiple myeloma (MM) patients with renal insufficiency using bortezomib- or thalidomide based regimens as front line treatment. Method: Sixty-nine newly diagnosed MM patients with renal insufficiency were retrospectively analyzed from August 2006 to August 2014. Results: 1 Among thirty-nine patients with bortezomib based regimens (the bortezomib group), the overall response rate (ORR) was 89.7% and complete response (CR) plus near CR(nCR) rate was 41.0%. By contrast, among thirty patients with thalidomide based regimens (the thalidomide group), the ORR was 83.3% and CR+ nCR rate was 26.7%. There was no significant difference of either ORR or CR+ nCR rate between bortezomib and thalidomide groups. 2 The improvement rate of renal function in bortezomib group and thalidomide group were 87.2% and 60.0% respectively (P=0.012). The median duration time of renal injury was 45 days in 52 patients with renal function improved, which was significantly shorter compared with 222 days in 17 patients without improvement (P<0.05). There was no difference of median serum creatinine and creatinine clearance rate between the two groups.3 The median progression-free survival (PFS) and the overall survival (OS) were 18 and 33.5 months, respectively in all patients. The three-year and five-year OS rates were 57% and 17%, respectively. The median PFS was 19 months in bortezomib group, while it was only 12 months in thalidomide group (P=0.023). The median OS were 36.5 months and 25.5 months respectively, which was no difference (P=0.285). Conclusions: The newly diagnosed MM patients with renal insufficiency could get higher ORR and the longer PFS using bortezomib containing regimens as initial therapy. Meanwhile the improvement rate of renal function and the living quality in patients with bortezomib are better compared with those with thalidomide based treatment.

AB - Objective: To study the clinical characteristics of childhood- and adolescent- onset hypoparathyroidism. Methods: The clinical data of 128 hypoparathyroidism patients with onset before the age of 18 years were collected and analyzed retrospectively. Results: The predominant features of the hypoparathyroidism were carpopedal spasm (89.3%, 108/121) and seizures (66.1%, 84/127). Intracranial calcification was identified in 89.4%(101/113) of the patients. Duration is an independent predictive factor (OR=1.483, P=0.011) for intracranial calcification. All the patients were treated with calcium and vitamin D or its metabolites. Hypercalciuria was associated with serum calcium (P=0.016). Conclusions: Carpopedal spasm and seizures were the main manifestations of childhood- and adolescent- onset hypoparathyroidism. Calcium and vitamin D or its metabolites are effective. Monitoring the concentration of serum and urinary calcium is of highly importance for the prevention of hypercalciuria. PMID- 27686438 TI - [The clinical feature and microbiological etiology of patients with infective endocarditis]. AB - Objective: To investigate the clinical features, pathogenic distribution and drug susceptibility of patients with infective endocarditis (IE). Methods: Clinical data of IE patients were collected, who were admitted to Capital Medical University Affiliated Beijing Anzhen Hospital from January 2012 to March 2015. Results: Three hundred and three IE patients were enrolled with age of (43+/-16) years old. Fever (85.5%)and cardiac murmur (62.4%)were the most common clinical presentations. Congenital heart diseases was the leading underlying diseases in IE patients. Non rheumatic valve diseases (13.5%) followed. Vegetations were found in 90.4%(274/303) patients. Streptococcus which accounted for 44.2% was the major pathogen of IE. Staphylococcus (28.9%)was the second common pathogen. Gram negative bacteria were diversified in categories. Gram-positive cocci were consistently sensitive to vancomycin and linezolid. Conclusions: Congenital heart disease is the main underlying disease related to IE. Streptococcus is still the primary pathogen. Gram-positive cocci keep good sensitivity to vancomycin and linezolid. PMID- 27686439 TI - [The correlation between optic nerve sheath diameter and volume status in patients after cardiac surgery]. AB - Objective: To investigate the relationship between optic nerve sheath diameter (ONSD) and volume status of patients after cardiac surgery. Methods: A total of consecutive 56 patients who were treated in Critical Care Unit in Peking Union Medical College Hospital after open heart surgery from January to August 2015 were screened in this study. Central venous pressure (CVP) and 72 h net fluid balance were monitored. ONSD and diameter of inferior vena cava (IVC) were measured by ultrasound. Results: A total of 44 patients were finally included in the study. The postoperative baseline ONSD was (5.31+/-1.96)mm, compared to (5.07+/-1.77)mm after 72 h treatment, with DeltaONSD(0.22+/-0.21)mm. Baseline and post-treatment at 72 h CVP were (11.98+/-4.09)mmHg and (8.95+/-4.02)mmHg respectively. IVC dropped from (19.75+/-4.12)mm to (17.11+/-4.68)mm. DeltaONSD and DeltaCVP were significantly correlated (r=0.422, P<0.05), DeltaONSD and net fluid balance (NFB) at 72 h were significantly correlated (r=-0.388, P<0.05). While DeltaONSD were significantly correlated with DeltaIVC (r=0.423, P<0.05), DeltaCVP and DeltaIVC were also significantly correlated (r=0.391, P<0.05). Conclusion: The change of ONSD in patients after cardiac surgery is related to the change of volume status. Therefore ONSD is helpful to estimate brain edema, not only could be a potential index to evaluate volume status, but also be used to guide improving prognosis after cardiac surgery.

AB - Objective: To evaluate the effects of tidal volume on the survival in adult patients without acute respiratory distress syndrome (non-ARDS). Methods: We searched relevant clinical randomized controlled trials (RCT) from January 2000 to December 2015. Meta analyses related to the effects of tidal volume on mortality in non-ARDS adults were conducted using the methods recommended by the Cochrane Collaboration. Results: A total of nineteen RCTs (n=1 679) were finally included. There were 838 patients ventilated with low tidal volume, and the other 841 patients ventilated with normal tidal volume. The mortality rates were not significantly different between low tidal volume group and control group (5.87% vs 6.52%; RR=0.9, P=0.58). But respiratory complications were significantly lower in low tidal volume group, such as development of acute respiratory distress syndrome(RR=0.32, 95% CI 0.16-0.63, P=0.001), pneumonia (RR=0.48, 95%CI 0.29 0.78, P=0.003), while the incidence of atelectasis was quite comparable between two groups (RR=0.78, 95%CI 0.391-1.356, P=0.48). Conclusion: Non-ARDS patients ventilated with low tidal volume is associated with a lower risk of pulmonary complications, yet clinical outcome, mainly mortality is similar to that of patients with regular tidal volume.

The response rates of interferon plus IM versus second generation TKI in CML-CP with non-T315I ABL kinase domain mutations were comparable (61.11% vs 65.52%, P>0.05). When CML-CP patients with ABL kinase domain mutations were resistant to TKI or not accessible to second-generation TKI, interferon plus IM can be an alternative choice.

AB - BACKGROUND: Somatotype is a complex trait influenced by different genetic and environmental factors as well as by other covariates whose effects are still unclear. AIMS: To (1) estimate siblings' resemblance in their general somatotype; (2) identify sib-pair (brother-brother (BB), sister-sister (SS), brother-sister (BS)) similarities in individual somatotype components; (3) examine the degree to which between and within variances differ among sib-ships; and (4) investigate the effects of physical activity (PA) and family socioeconomic status (SES) on these relationships. SUBJECTS AND METHODS: The sample comprises 1058 Portuguese siblings (538 females) aged 9-20 years. Somatotype was calculated using the Health-Carter method, while PA and SES information was obtained by questionnaire. Multi-level modelling was done in SuperMix software. RESULTS: Older subjects showed the lowest values for endomorphy and mesomorphy, but the highest values for ectomorphy; and more physically active subjects showed the highest values for mesomorphy. In general, the familiality of somatotype was moderate (rho = 0.35). Same-sex siblings had the strongest resemblance (endomorphy: rhoSS > rhoBB > rhoBS; mesomorphy: rhoBB = rhoSS > rhoBS; ectomorphy: rhoBB > rhoSS > rhoBS). For the ectomorphy and mesomorphy components, BS pairs showed the highest between sib ship variance, but the lowest within sib-ship variance; while for endomorphy BS showed the lowest between and within sib-ship variances. CONCLUSIONS: These results highlight the significant familial effects on somatotype and the complexity of the role of familial resemblance in explaining variance in somatotypes.

The microRNAs (miRNAs) have been identified to mediate chemotherapy drug resistance. MiR-451 as a tumor suppressor has been evaluated its potential effect on the sensitivity of cancer cells to DDP. However, the role of miR-451 in regulatory mechanism of chemosensitivity in lung cancer cells is still largely unknown. In this study, we first constructed a cisplatin-resistant A549 cell line (A549/DPP) accompanied with a decreased expression of miR-451 and an increased expression of Mcl-1in the drug resistant cells compared with the parental cells. Exogenous expression of miR-451 level in A549/DPP was found to sensitize their reaction to the treatment of cisplatin, which coincides with reduced expression of Mcl-1. Interestingly, Mcl-1 knockdown in A549/DPP cells increased the chemosensitivity to DPP, suggesting the dependence of Mcl-1 regulation in miR-451 activity. Moreover, miR-451 can restore cisplatin treatment response in cisplatin-resistant xenografts in vivo, while Mcl-1 protein levels were decreased. Thus, these findings provided that in lung cancer cells, tumor suppressor miR-451 enhanced DPP sensitivity via regulation of Mcl-1 expression, which could be served as a novel therapeutic target for the treatment of chemotherapy resistant in lung cancer. PMID- 27686451 TI - Dihydromyricetin suppresses TNF-alpha-induced NF-kappaB activation and target gene expression. AB - Nuclear factor-kappa B (NF-kappaB) has been reported to play a pivotal role in many physiological processes including inflammation, apoptosis, and angiogenesis. We discovered a potent natural NF-kappaB inhibitor, dihydromyricetin, from the traditional herb Ampelopsis grossedentata, which has a long history of use in food and medicine. In this study, we demonstrated the effect of dihydromyricetin on NF-kappaB activation in TNF-alpha-induced HeLa cells. Dihydromyricetin was found to markedly inhibit the phosphorylation and degradation of the inhibitor of NF-kappaB alpha (IkappaBalpha), and subsequent nuclear translocation of p65. Dihydromyricetin also has an impact on upstream signaling of IKK through the inhibition of expression of adaptor proteins, TNF receptor-associated factor 2 (TRAF2), and receptor-interacting protein 1 (RIP1). Furthermore, the current results reveal that dihydromyricetin led to the downregulation of target genes involved in inflammation, proliferation, as well as potentiation of TNF-alpha induced apoptosis through suppressing the activation of NF-kappaB. In conclusion, our data indicate that dihydromyricetin may be a potentially useful therapeutic agent for inflammatory diseases. PMID- 27686453 TI - Adenosine monophosphate-activated protein kinase activation and suppression of inflammatory response by cell stretching in rabbit synovial fibroblasts. AB - Joint mobilization is known to be beneficial in osteoarthritis (OA) patients. This study aimed to investigate the effect of stretching on adenosine monophosphate-activated protein kinase (AMPK) activity and its role in modulating inflammation in rabbit synovial fibroblasts. Uniaxial stretching of isolated rabbit synovial fibroblasts for ten min was performed. Stretching-induced AMPK activation, its underlying mechanism, and its anti-inflammatory effect were investigated using Western blot. Static stretching at 20 % of initial length resulted in AMPK activation characterized by expression of phosphorylated AMPK and phosphorylated acetyl-Co A carboxylase. AMP-activated protein kinase phosphorylation peaked 1 h after stretching and declined toward resting activity. Using cell viability assays, static stretching did not appear to cause cellular damage. Activation of AMPK involves Ca2+ influx via a mechanosensitive L-type Ca2+ channel, which subsequently raises intracellular Ca2+ and activates AMPK via Ca2+/calmodulin-dependent protein kinase kinase beta (CaMKKbeta). Interestingly, stretching suppressed TNFalpha-induced expression of COX-2, iNOS, and phosphorylated NF-kappaB. These effects were prevented by pretreatment with compound C, an AMPK inhibitor. These results suggest that mechanical stretching suppressed inflammatory responses in synovial fibroblasts via a L-type Ca2+ channel-CaMKKbeta-AMPK-dependent pathway which may underlie joint mobilization's ability to alleviate OA symptoms. PMID- 27686454 TI - Chronic intermittent hypoxia affects the cytosolic phospholipase A2alpha/cyclooxygenase 2 pathway via beta2-adrenoceptor-mediated ERK/p38 stimulation. AB - Cardiac resistance against acute ischemia/reperfusion (I/R) injury can be enhanced by adaptation to chronic intermittent hypoxia (CIH), but the changes at the molecular level associated with this adaptation are still not fully explored. Phospholipase A2 (PLA2) plays an important role in phospholipid metabolism and may contribute to membrane destruction under conditions of energy deprivation during I/R. The aim of this study was to determine the effect of CIH (7000 m, 8 h/day, 5 weeks) on the expression of cytosolic PLA2alpha (cPLA2alpha) and its phosphorylated form (p-cPLA2alpha), as well as other related signaling proteins in the left ventricular myocardium of adult male Wistar rats. Adaptation to CIH increased the total content of cPLA2alpha by 14 % in myocardial homogenate, and enhanced the association of p-cPLA2alpha with the nuclear membrane by 85 %. The total number of beta-adrenoceptors (beta-ARs) did not change but the beta2/beta1 ratio markedly increased due to the elevation of beta2-ARs and drop in beta1-ARs. In parallel, the amount of adenylyl cyclase decreased by 49 % and Gialpha proteins increased by about 50 %. Besides that, cyclooxygenase 2 (COX-2) and prostaglandin E2 (PGE2) increased by 36 and 84 %, respectively. In parallel, we detected increased phosphorylation of protein kinase Calpha, ERK1/2 and p38 (by 12, 48 and 19 %, respectively). These data suggest that adaptive changes induced in the myocardium by CIH may include activation of cPLA2alpha and COX-2 via beta2 AR/Gi-mediated stimulation of the ERK/p38 pathway. PMID- 27686455 TI - Serum levels of 25-hydroxyvitamin D are associated with periodontal disease. AB - OBJECTIVES: Vitamin D plays an essential role in bone metabolism as well as in immunity. Hence, it might affect the development and extent of periodontal disease. The aim of this study was the assessment of 25-hydroxyvitamin D (25(OH)D) status in periodontal disease. MATERIALS AND METHODS: Twenty-nine patients with severe periodontal disease and 29 healthy volunteers were recruited in this case-control-study. Serum 25(OH)D levels, Periodontal Probing Depth (PPD), Clinical Attachment Level (CAL), Bleeding on Probing (BOP), Body Mass Index (BMI), and current smoking status and smoking history (packyears) were assessed in all participants. Serum 25(OH)D levels were compared between controls and cases. Multivariable logistic regression was used to determine the odds ratio (OR) and 95 % confidence interval (CI) for periodontal disease in 25(OH)D deficient probands. RESULTS: Patients with periodontal disease presented a significantly higher proportion of deficient 25(OH)D levels (i.e., <50 nmol/l) compared to healthy controls (48 vs. 14 % respectively). The adjusted OR for periodontal disease with vitamin D deficiency was 1.5 (95 % CI, 1.13-1.98). No correlation between serum 25(OH)D levels and CAL, PPD, and BOP in the group with periodontal disease was found. CONCLUSIONS: In this case-control-study 25(OH)D deficiency is significantly associated with periodontal disease. CLINICAL RELEVANCE: The assessment of vitamin D levels in patients presenting with periodontal disease seems advisable, as vitamin D deficiency might be involved in the onset and progression of periodontal disease. PMID- 27686456 TI - The utilization of spitz-related nomenclature in the histological interpretation of cutaneous melanocytic lesions by practicing pathologists: results from the M Path study. AB - BACKGROUND: Spitz nevi, atypical Spitz tumors and spitzoid melanomas ('spitzoid lesions') represent controversial and poorly understood cutaneous melanocytic lesions that are difficult to diagnose histologically. It is unknown how these terms are used by pathologists. METHODS: We describe use of Spitz-related terminology using data from the Melanoma Pathology (M-Path) study database comprising pathologists' interpretations of biopsy slides, a nation-wide study evaluating practicing US pathologists' (N = 187) diagnoses of melanocytic lesions (8976 independent diagnostic assessments on 240 total test cases, with 1 slide per case). RESULTS: Most pathologists (90%) used the Spitz-related terminology. However, significant variation exists in which specific lesions were diagnosed as spitzoid and in the corresponding treatment recommendations. Recommendations ranged from 'no further treatment' to 'wide excision of 10 mm or greater' with no category capturing more than 50% of responses. For spitzoid melanoma diagnoses, 90% of pathologists recommended excision with >=10 mm margin. Pathologists report less confidence in diagnosing these lesions compared with other melanocytic proliferations and are more likely to request second opinions and additional clinical information (all p < 0.05). CONCLUSIONS: Spitzoid lesions are often not classified in any standardized way, evoke uncertainty in diagnosis by pathologists, and elicit variability in treatment recommendations. PMID- 27686457 TI - The effect of statins on influenza-like illness morbidity and mortality. AB - PURPOSE: The effect of statins on cytokine-mediated inflammatory responses may impact on the prognosis of influenza. We assessed whether statin use decreases the incidence of adverse influenza-related outcomes. Additionally, we used a new user study design to minimize healthy user bias. We further examined the possibility of non-causal associations by using unrelated outcomes. METHODS: We used the UK Clinical Practice Research Datalink to identify all patients aged 30 or older diagnosed with influenza-like illness during 1997-2010. Statin users were compared with propensity score-matched patients not receiving statins. The outcome was hospitalization for influenza or pneumonia or death in the 30 days following influenza diagnosis. Logistic regression estimated cumulative incidence ratios. RESULTS: The study cohort included 5181 statin users matched to 5181 non users. The 30-day incidence of hospitalization or death was 3.5% in statin users and 5.2% in non-users, resulting in a 27% lower incidence with statin use (cumulative incidence ratio: 0.73, 95%CI: 0.59-0.89). New statin users were less protected against our composite outcome. The effect of statins was less pronounced among those with respiratory and cardiac disease. Statin use was shown to be associated with a non-statistically significant risk reduction of motor vehicle accident and burns. CONCLUSION: The attenuation of the effect of statins with the new-user design, supporting evidence from the assessment of effect modification, and additional sub-analyses evaluating the effect of statins on non related outcomes suggest that the beneficial effect of statins on influenza related adverse outcomes may be explained by a healthy user bias.

AB - PURPOSE: To identify weak points in daily routine use of radiation therapy (RT) for non-metastatic breast cancer patients, particularly when data are lacking or equivocal, a "think tank" of experts met in Assisi. METHODS: Before the meeting, controversial issues on non-metastatic breast cancer were identified and reviewed, and clinical practice investigated by means of an online questionnaire. During the 3-day meeting, topics were discussed in-depth with attendees and potential sponsors that are involved in breast cancer treatment. RESULTS: Three issues were identified as needing further investigation: (1) Regional lymph node treatment in early-stage breast cancer; (2) Combined post-mastectomy RT and breast reconstruction; (3) RT in patients treated with primary systemic therapy. Future research proposals included the following: (1) Participating in appropriately selected on-going clinical trials; (2) Designing new randomized controlled clinical trials and prospective population cohort studies; (3) Setting up large database(s) to generate predictive response models and detect biomarkers for tailored loco-regional treatments. CONCLUSIONS: It is hoped that the ATTM findings, as described in the present white paper, will stimulate a new generation of radiation oncologists to focus on research in these areas, and that the white paper will become a tool for multidisciplinary groups to help them design research proposals and strategies. PMID- 27686461 TI - Characterization of the LBD gene family in Brachypodium: a phylogenetic and transcriptional study. AB - KEY MESSAGE: An unambiguous nomenclature is proposed for the twenty-eight-member LOB domain transcription factor family in Brachypodium . Expression analysis provides unique transcript patterns that are characteristic of a wide range of organs and plant parts. LOB (lateral organ boundaries)-domain proteins define a family of plant-specific transcription factors involved in developmental processes from embryogenesis to seed production. They play a crucial role in shaping the plant architecture through coordinating cell fate at meristem to organ boundaries. Despite their high potential importance, our knowledge of them is limited, especially in the case of monocots. In this study, we characterized LOB domain protein coding genes (LBDs) of Brachypodium distachyon, a model plant for grasses, and present their phylogenetic relationships and an overall spatial expression study. In the Brachypodium genome database, 28 LBDs were found and then classified based on the presence of highly conserved LOB domain motif. Their transcript amounts were measured via quantitative real-time RT-PCR in 37 different plant parts from root tip to generative organs. Comprehensive phylogenetic analysis suggests that there are neither Brachypodium- nor monocot specific lineages among LBDs, but there are differences in terms of complexity of subclasses between monocots and dicots. Although LBDs in Brachypodium have wide variation of tissue-specific expression and relative transcript levels, overall expression patterns show similarity to their counterparts in other species. The varying transcript profiles we observed support the hypothesis that Brachypodium LBDs have diverse but conserved functions in plant organogenesis. PMID- 27686463 TI - Increased revision rate with posterior tibial tunnel placement after using the 70 degree tibial guide in ACL reconstruction. AB - PURPOSE: To map knee morphology radiographically in a population with a torn ACL and to investigate whether anatomic factors could be related to outcomes after ACL reconstruction at mid- to long-term follow-up. Further, we wanted to assess tibial tunnel placement after using the 70-degree "anti-impingement" tibial tunnel guide and investigate any relation between tunnel placement and revision surgery. METHODS: Patients undergoing ACL reconstruction involving the 70-degree tibial guide from 2003 to 2008 were included. Two independent investigators analysed pre- and post-operative radiographs. Demographic data and information on revision surgery were collected from an internal database. Anatomic factors and post-operative tibial tunnel placements were investigated as predictors of revision. RESULTS: Three-hundred and seventy-seven patients were included in the study. A large anatomic variation with significant differences between men and women was seen. None of the anatomic factors could be related to a significant increase in revision rate. Patients with a posterior tibial tunnel placement, defined as 50 % or more posterior on the Amis and Jakob line, did, however, have a higher risk of revision surgery compared to patients with an anterior tunnel placement (P = 0.03). CONCLUSION: Use of the 70-degree tibial guide did result in a high incidence (47 %) of posterior tibial tunnel placements associated with an increased rate of revision surgery. The current study was, however, not able to identify any anatomic variation that could be related to a higher risk of revision surgery. Avoiding graft impingement from the femoral roof in anterior tibial tunnel placements is important, but the insight that overly posterior tunnel placement can lead to inferior outcome should also be kept in mind when performing ACL surgery. LEVEL OF EVIDENCE: IV. PMID- 27686464 TI - RNAi prevents and reverses phenotypes induced by mutant human ataxin-1. AB - OBJECTIVE: Spinocerebellar ataxia type 1 is an autosomal dominant fatal neurodegenerative disease caused by a polyglutamine expansion in the coding region of ATXN1. We showed previously that partial suppression of mutant ataxin-1 (ATXN1) expression, using virally expressed RNAi triggers, could prevent disease symptoms in a transgenic mouse model and a knockin mouse model of the disease, using a single dose of virus. Here, we set out to test whether RNAi triggers targeting ATXN1 could not only prevent, but also reverse disease readouts when delivered after symptom onset. METHODS: We administered recombinant adeno associated virus (rAAV) expressing miS1, an artificial miRNA targeting human ATXN1 mRNA (rAAV.miS1), to a mouse model of spinocerebellar ataxia type 1 (SCA1; B05 mice). Viruses were delivered prior to or after symptom onset at multiple doses. Control B05 mice were treated with rAAVs expressing a control artificial miRNA, or with saline. Animal behavior, molecular phenotypes, neuropathology, and magnetic resonance spectroscopy were done on all groups, and data were compared to wild-type littermates. RESULTS: We found that SCA1 phenotypes could be reversed by partial suppression of human mutant ATXN1 mRNA by rAAV.miS1 when delivered after symptom onset. We also identified the therapeutic range of rAAV.miS1 that could prevent or reverse disease readouts. INTERPRETATION: SCA1 disease may be reversible by RNAi therapy, and the doses required for advancing this therapy to humans are delineated. Ann Neurol 2016;80:754-765. PMID- 27686465 TI - Systematic review to establish absolute standards for technical performance in surgery. AB - BACKGROUND: Standard setting allows educators to create benchmarks that distinguish between those who pass and those who fail an assessment. It can also be used to create standards in clinical and simulated procedural skill. The objective of this review was to perform a systematic review of the literature using absolute standard-setting methodology to create benchmarks in technical performance. METHODS: A systematic review was conducted by searching MEDLINE, Embase, PsycINFO and the Cochrane Database of Systematic Reviews. Abstracts of retrieved studies were reviewed and those meeting the inclusion criteria were selected for full-text review. The quality of evidence presented in the included studies was assessed using the Medical Education Research Study Quality Instrument (MERSQI), where a score of 14 or more of 18 indicates high-quality evidence. RESULTS: Of 1809 studies identified, 37 used standard-setting methodology for assessment of procedural skill. Of these, 24 used participant centred and 13 employed item-centred methods. Thirty studies took place in a simulated environment, and seven in a clinical setting. The included studies assessed residents (26 of 37), fellows (6 of 37) and staff physicians (17 of 37). Seventeen articles achieved a MERSQI score of 14 or more of 18, whereas 20 did not meet this mark. CONCLUSION: Absolute standard-setting methodologies can be used to establish cut-offs for procedural skill assessments. PMID- 27686466 TI - Cytological and biophysical comparative analysis of cell structures at the microsporogenesis stage in sterile and fertile Allium species. AB - MAIN CONCLUSION: Using a live-cell-imaging approach and autofluorescence-spectral imaging, we showed quantitative/qualitative fluctuations of chemical compounds within the meiocyte callose wall, providing insight into the molecular basis of male sterility in plants from the genus Allium. Allium sativum (garlic) is one of the plant species exhibiting male sterility, and the molecular background of this phenomenon has never been thoroughly described. This study presents comparative analyses of meiotically dividing cells, which revealed inhibition at the different microsporogenesis stages in male-sterile A. sativum plants (cultivars Harnas and Arkus) and sterile A. ampeloprasum var. ampeloprasum (GHG-L), which is phylogenetically related to garlic. Fertile species A. ampeloprasum (leek) was used as the control material, because leek is closely related to both garlic and GHG-L. To shed more light on the molecular basis of these disturbances, autofluorescence-spectral imaging of live cells was used for the assessment of the biophysical/biochemical differences in the callose wall, pollen grain sporoderm, and the tapetum in the sterile species, in comparison with the fertile leek. The use of techniques for live-cell imaging (autofluorescence-spectral imaging) allowed the observation of quantitative/qualitative fluctuations of autofluorescent chemical compounds within the meiocyte callose wall. The biophysical characterisation of the metabolic disturbances in the callose wall provides insight into the molecular basis of male sterility in A. sativum. In addition, using this method, it was possible for the first time, to determine precisely (on the basis of fluctuations of autofluorescence compounds) the meiosis stage in which normal microsporogenesis is disturbed, which was not visible using light microscopy. PMID- 27686467 TI - Stilbene accumulation and expression of stilbene biosynthesis pathway genes in wild grapevine Vitis amurensis Rupr. AB - MAIN CONCLUSION: We detected and quantified six stilbenes ( cis -piceid, t piceid, t -epsilon-viniferin, cis -epsilon-viniferin, t -resveratrol, and t delta-viniferin) in the leaves, petioles, berry skins, and seeds of wild-growing Vitis amurensis . The highest content of stilbenes and expression of stilbene biosynthesis genes were in the probes collected in the autumn and after ultraviolet elicitation. Stilbenes, including the best-studied stilbene resveratrol, are known to display valuable bioactivities and protect plants against various pathogens. There is a lack of studies on stilbene quantities and spectrum combined with an analysis of the stilbene biosynthesis pathway gene expression in Vitaceae species, despite grapevine is an important source of stilbenes. This study presents an analysis of stilbene spectrum, stilbene content, and expression of stilbene biosynthesis genes both in natural conditions and after ultraviolet (UV-C) elicitation in the leaves, petioles, berry skins, and seeds of wild-growing Vitis amurensis, a highly stress-tolerant plant species. Using HPLC analysis, we detected six main stilbenes: cis-piceid (up to 0.257 mg/g of dry weight (DW) of plant material), t-piceid (up to 0.055 mg/g DW), t-epsilon-viniferin (up to 0.122 mg/g DW), cis-epsilon-viniferin (up to 0.031 mg/g DW), t-resveratrol (from 0.004 to 0.121 mg/g DW), and t-delta-viniferin (up to 0.019 mg/g DW). The stilbenes were actively synthesized in the leaves (total stilbenes 0.39 mg/g DW) and berry skins (total stilbenes 0.249 mg/g DW) of V. amurensis collected in the autumn. qRT-PCR revealed that the stilbene synthase (STS), resveratrol O-glucosyltransferase (Glu1), and polyphenol oxidase (PPO1) genes were actively expressed in the analyzed tissues. The resveratrol methyltransferase (Romt1) gene, which is known to catalyze biosynthesis of pterostilbene, was also expressed, but no pterostilbene has been detected in V. amurensis. The content of all detected stilbenes and expression of stilbene biosynthesis genes increased after UV-C treatment, except for Romt1. The data are important for understanding the stilbene biosynthesis in grapevine. PMID- 27686468 TI - Diagnostic utility of a computer-aided diagnosis system for whole-body bone scintigraphy to detect bone metastasis in breast cancer patients. AB - OBJECTIVE: To compare the diagnostic ability of planar images (PI) and images obtained by a computer-aided diagnosis (CAD) system (Viewer for Standardized Bone Scintigraphies; VSBONE) of whole-body bone scintigraphy for detecting bone metastases in breast cancer patients. METHODS: 81 women (median: 56 years; range: 32-79) with a history of breast cancer were included in this study. They underwent whole-body bone scintigraphy after intravenous injection of 740 MBq technetium-99m hydroxymethylene diphosphonate. A total of 1066 bones (162 regions of the skull, 657 regions of the spine and pelvis, 223 regions of the sternum and rib, 18 regions of the upper extremities, and 6 regions of the lower extremities) were analyzed. The PI alone, VSBONE images alone, and both PI and VSBONE images (PI + VSBONE) were interpreted independently by two radiologists to diagnose bone metastases, which were then confirmed by magnetic resonance imaging. The sensitivity and specificity for each modality were analyzed using Fisher's exact and McNemar tests. Inter-reviewer agreement was evaluated using a kappa statistic. RESULTS: Bone metastases were confirmed in 43 patients with 442 positive lesions. The average sensitivity of PI, VSBONE images, and PI + VSBONE images was 40.8, 50.2, and 61.8 %, respectively. The average specificity was 97.8, 97.5, and 97.6 %, respectively. The kappa scores were 0.62 for PI, 0.69 for VSBONE, and 0.77 for PI + VSBONE. CONCLUSIONS: VSBONE was superior to PI in regard to sensitivity for detecting bone metastases in breast cancer patients. However, an improved CAD system is required to decrease the number of false negative results. PMID- 27686469 TI - Intratumoral heterogeneity of 18F-FLT uptake predicts proliferation and survival in patients with newly diagnosed gliomas. AB - BACKGROUND: The nucleoside analog 3'-deoxy-3'-18F-fluorothymidine (FLT) has been investigated for evaluating tumor proliferating activity in brain tumors. We evaluated FLT uptake heterogeneity using textural features from the histogram analysis in patients with newly diagnosed gliomas and examined correlation of the results with proliferative activity and patient prognosis, in comparison with the conventional PET parameters. METHODS: FLT PET was investigated in 37 patients with newly diagnosed gliomas. The conventional parameters [tumor-to-contralateral normal brain tissue (T/N) ratio and metabolic tumor volume (MTV)] and textural parameters (standard deviation, skewness, kurtosis, entropy, and uniformity) were derived from FLT PET images. Linear regression analysis was used to compare PET parameters and the proliferative activity as indicated by the Ki-67 index. The associations between parameters and overall survival (OS) were tested by Cox regression analysis. RESULTS: Median OS was 662 days. For the conventional parameters, linear regression analysis indicated a significant correlation between T/N ratio and Ki-67 index (p = 0.02) and MTV and Ki-67 index (p = 0.02). Among textural parameters, linear regression analysis indicated a significant correlation for kurtosis (p = 0.003), entropy (p < 0.001), and uniformity (p < 0.001) as compared to Ki-67 index, exceeding those of the conventional parameters. The results of univariate analysis suggested that skewness and kurtosis were associated with OS (p = 0.03 and 0.02, respectively). Mean survival for patients with skewness values less than 0.65 was 1462 days, compared with 917 days for those with values greater than 0.65 (p = 0.02). Mean survival for patients with kurtosis values less than 6.16 was 1616 days, compared with 882 days for those with values greater than 6.16 (p = 0.006). CONCLUSIONS: Based on the results of this preliminary study in a small patient population, textural features reflecting heterogeneity on FLT PET images seem to be useful for the assessment of proliferation and for the potential prediction of survival in newly diagnosed gliomas. PMID- 27686470 TI - Risk Factors for Return to the Operating Room after Resident-Performed Cataract Surgery. AB - OBJECTIVE: Investigate risk factors for unplanned return to the operating room after resident-performed cataract surgery. DESIGN: Retrospective case-control study. SETTING: Institutional. METHODS: Study population: All patients with reoperation within 90 days of resident-performed phacoemulsification were matched to four control eyes which had surgery within 30 days of the reoperation at the same institution. OBSERVATION PROCEDURE: Billing codes were used to identify all patients who underwent resident-performed intended phacoemulsification with intraocular lens placement from January 2005 to December 2010. MAIN OUTCOME MEASURES: Investigated risk factors for reoperation included cataract characteristics and preexisting ocular co-morbidities, including diabetic retinopathy, retinal detachment history, glaucoma, corneal pathology, and uveitis. Additional preoperative risk factors studied included resident training year, history of tamsulosin use, phacodonesis, pupillary dilation, presence of pseudoexfoliation, myopia, history of trauma, visual acuity, and monocular status. Intraoperative variables were the use of iris expansion devices, use of capsular stain, attending type, incision type, use of sutures, vitreous loss, anesthesia type, and phacoemulsification technique. RESULTS: There were 67 returns to the operating room (i.e., cases) over five years that were assigned to 268 control eyes. In preoperative multivariate analysis, phacoemulsification done by a first- or second-year resident (OR 3.2, 95% CI: 1.7-6.0, p < 0.001) was associated with an increased risk of reoperation. In postoperative multivariate analysis, only the use of the divide-and-conquer technique (OR 4.0, 95% CI:1.7 9.2, p = 0.001) was associated with an increased risk of reoperation. CONCLUSIONS: Phacoemulsification done by a junior resident or using the divide and-conquer technique had the highest risk of reoperation. PMID- 27686471 TI - Targeted de-escalation rounds may effectively and safely reduce meropenem use. AB - OBJECTIVE: Use of meropenem in our hospital has doubled in recent years. An audit in 2013 showed that although initiation of therapy with meropenem was generally appropriate, therapy was rarely subsequently reviewed and de-escalated where appropriate. Therefore, a structured stewardship initiative focussed on meropenem de-escalation was developed. METHODS: A local guideline for review and de escalation of meropenem was developed and approved by the Antimicrobial Stewardship Team. The guideline outlined clinical and microbiological criteria which when met should lead to recommendation for meropenem de-escalation. Implementation of the guideline was piloted for a period of 4 weeks by a consultant microbiologist and an antimicrobial pharmacist. Days of meropenem use and crude mortality in those in whom de-escalation was implemented were compared with those where de-escalation was not recommended or was recommended but not implemented. RESULTS: Thirty-three patients were reviewed. Overall, a recommendation to de-escalate from meropenem to a specified alternative antibiotic was made for 18 (55 %) patients. This advice was followed for 12 (36 %) patients. The median days of meropenem use in patients where meropenem was de escalated was 4.5 days (range 2-19) compared with 14 days (range 6-84) where de escalation was not recommended or the recommendation was not implemented. There was no statistically significant difference in crude mortality between patients de-escalated from meropenem and those where meropenem was continued. CONCLUSION: This pilot study suggests that targeted carbapenem de-escalation stewardship activity based on pre-determined criteria, while labour intensive, can effectively and safely reduce meropenem use in the acute hospital setting. PMID- 27686472 TI - Is intraoperative frozen section analysis of the proximal bile ducts in hilar cholangiocarcinoma of limited value? AB - Mantel et al. showed that the use of intraoperative frozen section analysis of the proximal bile ducts has a limited contribution in obtaining secondary R0 resections and final resection status had no impact on recurrence rate in hilar cholangiocarcinoma. However, the accuracy, sensitivity, and specificity of intraoperative frozen section analysis were determined by the specific pathologic features of the tumor and the different experienced pathologists in different pathology laboratories. It has been demonstrated that tumor-free resection margin (R0) is the most prognostic factor for survival, as well as the only factor that can be modified by the surgeons. Ribero et al. reported an improvement in prognosis was found in the secondary R0 group. As the conclusion given by Mantel et al. and Shingu et al., which is contrary to Ribero et al. Before the real role of intraoperative frozen section in the analysis of the margin of proximal bile ducts in treating hilar cholangiocarcinoma is concluded, further studies are still needed. PMID- 27686473 TI - The effect of the order in which episodic autobiographical memories versus autobiographical knowledge are shared on feelings of closeness. AB - Autobiographical memories (AMs) can be used to create and maintain closeness with others [Alea, N., & Bluck, S. (2003). Why are you telling me that? A conceptual model of the social function of autobiographical memory. Memory, 11(2), 165-178]. However, the differential effects of memory specificity are not well established. Two studies with 148 participants tested whether the order in which autobiographical knowledge (AK) and specific episodic AM (EAM) are shared affects feelings of closeness. Participants read two memories hypothetically shared by each of four strangers. The strangers first shared either AK or an EAM, and then shared either AK or an EAM. Participants were randomly assigned to read either positive or negative AMs from the strangers. Findings suggest that people feel closer to those who share positive AMs in the same way they construct memories: starting with general and moving to specific. PMID- 27686474 TI - Impurities in Drug Products and Active Pharmaceutical Ingredients. AB - Analytical methods should be selective and fast. In modern times, scientists strive to meet the criteria of green chemistry, so they choose analytical procedures that are as short as possible and use the least toxic solvents. It is quite obvious that the products intended for human consumption should be characterized as completely as possible. The safety of a drug is dependent mainly on the impurities that it contains. High pressure liquid chromatography and ultra high pressure liquid chromatography have been proposed as the main techniques for forced degradation and impurity profiling. The aim of this article was to characterize the relevant classification of drug impurities and to review the methods of impurities determination for atorvastatin (ATV) and duloxetine (DLX) (both in active pharmaceutical ingredients and in different dosage forms). These drugs have an impact on two systems of the human body: cardiac and nervous. Simple characteristics of ATV and DLX, their properties and specificity of action on the human body, are also included in this review. The analyzed pharmaceuticals ATV (brand name Lipiron) and DLX (brand name Cymbalta)-were selected for this study based on annual rankings prepared by Information Medical Statistics.

AB - BACKGROUND: We present an extremely rare case of tubo-ovarian abscesses involving Corynebacterium striatum (C. striatum) as causative agent in a 53-year-old woman. CASE PRESENTATION: The patient presented with stomach pain, chills, and nausea. Her medical history included poorly controlled psoriasis vulgaris and diabetes. Laboratory and imaging findings led to diagnosis of septic shock due to tubo ovarian abscesses. She was treated with antibiotic therapy and surgery to remove the left adnexa. Various cultures detected Prevotella spp. and C. striatum. We concluded that C. striatum from skin contaminated by psoriasis vulgaris had caused the tubo-ovarian abscesses by way of ascending infection. CONCLUSIONS: This may be the first known case of tubo-ovarian abscesses due to C. striatum. In patients whose skin has been weakened by psoriasis vulgaris or other infections, Corynebacterium should be considered as causative microorganisms, and antibiotic therapy including vancomycin should be administered. PMID- 27686476 TI - The effect of oral positioning on the hypopharyngeal airway. AB - OBJECTIVES: It is generally assumed that mouth opening decreases the hypopharyngeal cross-sectional area (HA) and that tongue protrusion (TP) increases the HA. We hypothesize that a substantial number of patients do not exhibit this expected pattern. STUDY DESIGN: Prospective cohort conducted at a tertiary academic center. METHODS: With a flexible fiberoptic scope in position, the hypopharyngeal airway was visualized and assessed in 189 patients with the mouth closed. Patients were then asked to open the mouth with the tongue in neutral position (MOTN) to determine the effect on the airway. The same methodology was used to compare the airway with the MOTN versus TP. Basic demographics, including age, gender, body mass index, and presence and severity of obstructive sleep apnea (OSA), were collected. Student t test, Mantel-Haenszel chi-square, and Cochran-Armitage analyses were assessed for significant relationships and trends with oral positions. RESULTS: Although mean HA decreased with MOTN (P < 0.0001), 33% of patients exhibited an increase in HA. Similarly, mean HA increased with TP (P = 0.0018); however, 38% of patients demonstrated a decrease in HA. There was no significant relationship in HA between OSA and non OSA patients. For those with OSA, increasing severity trended toward a higher incidence of smaller HA with TP (P = 0.038). CONCLUSION: The airway is typically most obstructed with mouth opening (MOTN) and most patent with tongue protrusion (TP). Nevertheless, hypopharyngeal changes with MOTN and TP followed a paradoxical pattern in one-third of our population. This may have implications in patient selection for targeted OSA treatment.

AB - BACKGROUND: Occupational identity (OI) is shaped by occupational experiences over time and has been studied among individuals with a variety of health conditions. Adolescents with ADHD face numerous challenges in their occupational performance that may threaten their OI. OBJECTIVE: This study sought to compare the occupational identities of adolescents with and without ADHD and to gain a deeper understanding of the characteristics of OI among adolescents with ADHD. METHODS: Sixty-four adolescents with (n = 21) and without ADHD (n = 43) were interviewed using the Occupational Performance History Interview (OPHI-II). A mixed methodology was applied, using quantitative and subsequent qualitative content analyses of 10 interviews, with a directed approach. RESULTS: OPHI-II OI interval scores and 7/11 items of the OI scale were significantly lower in the ADHD group compared to controls. In the qualitative content analyses, three major themes were found: (i) the meaning of success in academic participation, (ii) the consequences of not succeeding in academic participation and (iii) self explanations for not succeeding in academic participation. CONCLUSION: Findings demonstrate the presence of OI challenges among adolescents with ADHD. Occupational therapy intervention may be needed in order to promote occupational adaptation. PMID- 27686478 TI - Quassinoids isolated from Brucea javanica inhibit pepper mottle virus in pepper. AB - A green fluorescent protein (GFP)-tagged pepper mottle virus (PepMoV) based leaf disc method and systemic host method were developed to identify antiviral agents. Preliminary experiments using a PepMoV-GFP based leaf-disc method led to the isolation of five quassinoids, including brusatol (1), bruceantin (2), brucein A (3), bruceantinol (4), and brucein B (5), from the CH3OH extract of Brucea javanica. All isolated compounds exhibited inactivation effects in systemic host plants, and compounds 3 and 4 were potent, with a minimum inhibitory concentration of 10MUM. Furthermore, compound 3 was found to have a protective effect at the tested concentration of 40MUM. PMID- 27686479 TI - Tumor-homing effect of human mesenchymal stem cells in a TH-MYCN mouse model of neuroblastoma. AB - BACKGROUND: Human mesenchymal stem cells (hMSCs) are multipotent stem-like cells that are reported to have tumor-suppression effects and migration ability toward damaged tissues or tumors. The aim of this study was to analyze the tumor-homing ability of hMSCs and antitumor potency in a transgenic TH-MYCN mouse model of neuroblastoma (NB). METHODS: hMSCs (3*106) labeled with DiR, a lipophilic near infrared dye, were intraperitoneally (i.p.) or intravenously (i.v.) administered to the TH-MYCN mice. hMSC in vivo kinetics were assayed using the IVIS(r) imaging system for 24h after injection. Immunohistochemistry using human CD90 antibody was also performed to confirm the location of hMSCs in various organs and tumors. Furthermore, the survival curve of TH-MYCN mice treated with hMSCs was compared to a control group administered PBS. RESULTS: i.p. hMSCs were recognized in the tumors of TH-MYCN mice by IVIS. hMSCs were also located inside the tumor tissue. Conversely, most of the i.v. hMSCs were captured by the lungs, and migration into the tumors was not noted. There was no significant difference in the survival between the hMSC and control groups. CONCLUSION: The present study suggested that hMSCs may be potential tumor-specific therapeutic delivery vehicles in NB according to their homing potential to tumors. PMID- 27686480 TI - Fine clinical differences between patients with multifocal and diffuse hepatic hemangiomas. AB - BACKGROUND: It has been reported that multifocal and diffuse hepatic hemangiomas are true infantile hemangiomas for which a continuum probably exists. We determined the similarities and fine differences between the two types of hemangioma and identified the multifocal subgroup of type, which needs timely treatment. MATERIAL AND METHODS: Twenty-four patients (4 males and 20 females; age 114+/-142days) with multifocal or diffuse hepatic hemangiomas who were treated between January 2000 and June 2015 were studied. For the multifocal type, patients were divided into countable (MC) and uncountable (MU) subgroups. The medical data were analyzed retrospectively. RESULTS: The clinical presentations included hepatomegaly (n=11), dyspnea (n=7), heart failure (n=9), hypothyroidism (n=6), and anemia (n=1). There were 19 and 5 patients with multifocal and diffuse types, and 6 and 13 patients in the MC and MU groups, respectively. There were significant differences between the multifocal and diffuse types with respect to hepatomegaly, heart failure, dyspnea, and hypothyroidism. However, there was no difference between the MU group and the diffuse type except for hypothyroidism. Observation was commonly recommended for patients with the multifocal type, and their survival rate was clearly higher than for patients with the diffuse type. Both the MU and diffuse-type groups needed treatment, unlike MC patients. The complete remission rate was higher in the MC group than in the MU and diffuse type groups. Patients with the diffuse type were more likely to die. CONCLUSIONS: Patients with diffuse-type hepatic hemangioma are at high risk and need active treatment. The MU group for the multifocal type is unique and has high similarities to the diffuse type with respect to clinical presentation and treatment, which suggests that a continuum of the disease phenotypes exists.

AB - BACKGROUND/PURPOSE: The purpose of this study was to evaluate the association of insurance status on the probability of transfer of pediatric trauma patients to level I/II centers after initial evaluation at lower level centers. METHODS: A retrospective review of all pediatric trauma patients (age<16years) registered in the 2007-2012 National Trauma Data Bank was performed. Multiple regression techniques controlling for clustering at the hospital level were used to determine the impact of insurance status on the probability of transfer to level I/II trauma centers. RESULTS: Of 38,205 patients, 33% of patients (12,432) were transferred from lower level centers to level I/II trauma centers. Adjusting for demographics and injury characteristics, children with no insurance had a higher likelihood of transfer than children with private insurance. Children with public or unknown insurance status were no more likely to be transferred than privately insured children. There were no variable interactions with insurance status. CONCLUSIONS: Among pediatric trauma patients, lack of insurance is an independent predictor for transfer to a major trauma center. While burns, severely injured, and younger patients remain the most likely to be transferred, these findings suggest a triage bias influenced by insurance status. Additional policies may be needed to avoid unnecessary transfer of uninsured pediatric trauma patients. LEVEL OF EVIDENCE: Case-control study, level III. PMID- 27686482 TI - MEK inhibitors as a novel therapy for neuroblastoma: Their in vitro effects and predicting their efficacy. AB - BACKGROUND: A recent study reported that relapsed neuroblastomas had frequent RAS ERK pathway mutations. We herein investigated the effects and pathways of MEK inhibitors, which inhibit the RAS-ERK pathway, as a new molecular-targeted therapy for refractory neuroblastomas. METHOD: Five neuroblastoma cell lines were treated with trametinib (MEK inhibitor) or CH5126766 (RAF/MEK inhibitor). Growth inhibition was analyzed using a cell viability assay. ERK phosphorylation and the MYCN expression were analyzed by immunoblotting or immunohistochemistry. RAS/RAF mutations were identified by direct sequencing or through the COSMIC database. RESULTS: Both MEK inhibitors showed growth inhibition effects on cells with ERK phosphorylation, but almost no effect on cells without. In immunoblotting analyses, ERK phosphorylation and MYCN expression were suppressed in ERK active cells by these drugs. Furthermore, phosphorylated-ERK immunohistochemistry corresponded to the drug responses. Regarding the relationship between RAS/Raf mutations and ERK phosphorylation, ERK was phosphorylated in one cell line (NLF) without RAS/Raf mutations. CONCLUSION: MEK inhibitors are a promising molecular targeted therapeutic option for ERK active neuroblastomas. The efficacy of MEK inhibitors corresponds to ERK phosphorylation, while RAS/RAF mutations are not always detected in drug-sensitive cells. Phosphorylated-ERK immunohistochemistry is thus a useful method to analyze ERK activity and predict the therapeutic effects of MEK inhibitors. PMID- 27686483 TI - Treatment outcomes in pediatric melanoma-Are there benefits to specialized care? AB - PURPOSE: The purpose of this study was to evaluate the impact of hospital specialization on survival in pediatric melanoma. METHODS: We reviewed all patients under 18years old with cutaneous melanoma evaluated at MD Anderson Cancer Center, a National Cancer Institute (NCI)-designated center, from 2000 to 2014. We compared overall survival (OS) and disease-free survival (DFS) between patients who underwent all treatments at MDACC (Group A, n=146) and those who underwent initial surgical treatment at a non-NCI center (Group B, n=58). Kaplan Meier survival curves were compared using the log-rank test. RESULTS: Group A patients had significantly better OS and DFS (both p<0.001). Five-year OS was 97% (95% CI 92%-99%) in Group A versus 88% (95% CI 74%-94%) in Group B. Group survival differences were most notable in Stage 3 and 4 patients. Group A patients presenting with stage III or IV disease had a 5-year OS rate of 91.2% (95% CI 75.1%-97.1%) compared to 80.8% (95% CI 59.8%-91.5%) in Group B. The DFS rate was 94.4% (95% CI 88.5%-97.3%) in Group A versus 77.2% (95% CI 62.5%-86.7%) in Group B. CONCLUSION: Surgical treatment at a comprehensive cancer center may improve outcomes for pediatric melanoma especially for patients presenting with later stage disease.

PMID- 27686484 TI - Reinforcing the ventral penile shaft with pedicled fat/connective tissues before urethroplasty lowers the risk for post-urethroplasty complications in hypospadias. AB - PURPOSE: CHARGE is our technique for reinforcing the ventral penile shaft with pedicled pericordal/scrotal fat, pedicled perimeatal connective tissue, or a combination of these at the time of initial hypospadias surgery. Such pedicled grafts "charge" poorly developed urethral plates and thin ventral foreskin prior to urethroplasty to improve compromised vascular perfusion that could prevent post-urethroplasty complications (post-UPC). METHODS: We reviewed post-UPC in 179 staged hypospadias repair patients (1997-2015). CHARGE, adopted routinely in 2010 was used in 39 patients (C-group), not indicated in 7 because ventral connective tissue was thick, and not used in 133 (NC-group). Initial hypospadias surgery included foreskin degloving with or without chordectomy, dorsal plication, tunica albuginea incision, or a combination of these. RESULTS: Subject demographics were similar. NC had significantly more post-UPC than C (25 versus 0; p<.01) comprising stenosis (n=14), fistula (n=7), diverticulum (n=2), and wound infection (n=2) that developed after a mean of 0.7+/-0.2years (range: 1day 2.8years). Extra time taken for CHARGE was less than 15minutes in all cases. Mean follow-up after urethroplasty (years) was significantly shorter in C (1.5+/-1.0 versus 5.7+/-3.8) (p<.01), but almost double the time taken to develop post-UPC. CONCLUSION: CHARGE would appear to prevent post-UPC. LEVEL OF EVIDENCE: Retrospective Comparative Study - Level III. PMID- 27686485 TI - Clinicoradiologic Correlations of Cerebral Microbleeds in Advanced Age. AB - BACKGROUND AND PURPOSE: The presence of cerebral microbleeds has been associated with dementia and cognitive decline, although studies report conflicting results. Our aim was to determine the potential role of the presence and location of cerebral microbleeds in early stages of cognitive decline. MATERIALS AND METHODS: Baseline 3T MR imaging examinations including SWI sequences of 328 cognitively intact community-dwelling controls and 72 subjects with mild cognitive impairment were analyzed with respect to the presence and distribution of cerebral microbleeds. A neuropsychological follow-up of controls was performed at 18 months post inclusion and identified cases with subtle cognitive deficits were referred to as controls with a deteriorating condition. Group differences in radiologic parameters were studied by using nonparametric tests, 1-way analysis of variance, and Spearman correlation coefficients. RESULTS: Cerebral microbleed prevalence was similar in subjects with mild cognitive impairment and controls with stable and cognitively deteriorating conditions (25%-31.9%). In all diagnostic groups, lobar cerebral microbleeds were more common. They occurred in 20.1% of all cases compared with 6.5% of cases with deep cerebral microbleeds. None of the investigated variables (age, sex, microbleed number, location and depth, baseline Mini-Mental State Examination score, and the Fazekas score) were significantly associated with cognitive deterioration with the exception of education of >12 years showing a slight but significant protective effect (OR, 0.44; 95% CI, 0.22-0.92; P = .028). The Mini-Mental State Examination and the Buschke total score were correlated with neither the total number nor lobar versus-deep location of cerebral microbleeds. CONCLUSIONS: Cerebral microbleed presence, location, and severity are not related to the early stages of cognitive decline in advanced age. PMID- 27686486 TI - Genetics of Frontotemporal Dementia. PMID- 27686487 TI - Hippocampal and Deep Gray Matter Nuclei Atrophy Is Relevant for Explaining Cognitive Impairment in MS: A Multicenter Study. AB - BACKGROUND AND PURPOSE: The structural MR imaging correlates of cognitive impairment in multiple sclerosis are still debated. This study assessed lesional and atrophy measures of white matter and gray matter involvement in patients with MS acquired in 7 European sites to identify the MR imaging variables most closely associated with cognitive dysfunction. MATERIALS AND METHODS: Brain dual-echo, 3D T1-weighted, and double inversion recovery scans were acquired at 3T from 62 patients with relapsing-remitting MS and 65 controls. Patients with at least 2 neuropsychological tests with abnormal findings were considered cognitively impaired. Focal WM and cortical lesions were identified, and volumetric measures from WM, cortical GM, the hippocampus, and deep GM nuclei were obtained. Age- and site-adjusted models were used to compare lesion and volumetric MR imaging variables between patients with MS who were cognitively impaired and cognitively preserved. A multivariate analysis identified MR imaging variables associated with cognitive scores and disability. RESULTS: Twenty-three patients (38%) were cognitively impaired. Compared with those with who were cognitively preserved, patients with MS with cognitive impairment had higher T2 and T1 lesion volumes and a trend toward a higher number of cortical lesions. Significant brain, cortical GM, hippocampal, deep GM nuclei, and WM atrophy was found in patients with MS with cognitive impairment versus those who were cognitively preserved. Hippocampal and deep GM nuclei atrophy were the best predictors of cognitive impairment, while WM atrophy was the best predictor of disability. CONCLUSIONS: Hippocampal and deep GM nuclei atrophy are key factors associated with cognitive impairment in MS. These MR imaging measures could be applied in a multicenter context, with cognition as clinical outcome. PMID- 27686488 TI - Flow Conditions in the Intracranial Aneurysm Lumen Are Associated with Inflammation and Degenerative Changes of the Aneurysm Wall. AB - BACKGROUND AND PURPOSE: Saccular intracranial aneurysm is a common disease that may cause devastating intracranial hemorrhage. Hemodynamics, wall remodeling, and wall inflammation have been associated with saccular intracranial aneurysm rupture. We investigated how saccular intracranial aneurysm hemodynamics is associated with wall remodeling and inflammation of the saccular intracranial aneurysm wall. MATERIALS AND METHODS: Tissue samples resected during a saccular intracranial aneurysm operation (11 unruptured, 9 ruptured) were studied with histology and immunohistochemistry. Patient-specific computational models of hemodynamics were created from preoperative CT angiographies. RESULTS: More stable and less complex flows were associated with thick, hyperplastic saccular intracranial aneurysm walls, while slower flows with more diffuse inflow were associated with degenerated and decellularized saccular intracranial aneurysm walls. Wall degeneration (P = .041) and rupture were associated with increased inflammation (CD45+, P = .031). High wall shear stress (P = .018), higher vorticity (P = .046), higher viscous dissipation (P = .046), and high shear rate (P = .046) were associated with increased inflammation. Inflammation was also associated with lack of an intact endothelium (P = .034) and the presence of organized luminal thrombosis (P = .018), though overall organized thrombosis was associated with low minimum wall shear stress (P = .034) and not with the flow conditions associated with inflammation. CONCLUSIONS: Flow conditions in the saccular intracranial aneurysm are associated with wall remodeling. Inflammation, which is associated with degenerative wall remodeling and rupture, is related to high flow activity, including elevated wall shear stress. Endothelial injury may be a mechanism by which flow induces inflammation in the saccular intracranial aneurysm wall. Hemodynamic simulations might prove useful in identifying saccular intracranial aneurysms at risk of developing inflammation, a potential biomarker for rupture.

PMID- 27686489 TI - Comparison of Quantitative Cerebral Blood Flow Measurements Performed by Bookend Dynamic Susceptibility Contrast and Arterial Spin-Labeling MRI in Relapsing Remitting Multiple Sclerosis. AB - BACKGROUND AND PURPOSE: Quantitative CBF usage as a biomarker for cognitive impairment and disease progression in MS is potentially a powerful tool for longitudinal patient monitoring. Dynamic susceptibility contrast perfusion with bookend T1-calibration (bookend technique) and pseudocontinuous arterial spin labeling have recently been used for CBF quantification in relapsing-remitting MS. The noninvasive nature of pseudocontinuous arterial spin-labeling is advantageous over gadolinium-based techniques, but correlation between the techniques is not well-established in the context of MS. MATERIALS AND METHODS: We compared pseudocontinuous arterial spin-labeling CBF with the bookend technique in a prospective cohort of 19 healthy controls, 19 subjects with relapsing-remitting MS without cognitive impairment, and 20 subjects with relapsing-remitting MS with cognitive impairment on a voxelwise and Brodmann region basis. The linear Pearson correlation, SNR, and coefficient of variation were quantified. RESULTS: Voxelwise paired t tests revealed no significant CBF differences between techniques after normalization of global mean intensities. The highest Pearson correlations were observed in deep GM structures (average r = 0.71 for the basal ganglia and r = 0.65 for the thalamus) but remained robust for cortical GM, WM, and white matter lesions (average r = 0.51, 0.53, 0.54, respectively). Lower Pearson correlations were observed for cortical lesions (average r = 0.23). Brodmann region correlations were significant for all groups. All correlations were maintained in healthy controls and in patients with relapsing-remitting multiple sclerosis. The highest SNR was present in bookend perfusion, while the highest coefficient of variation was present in white matter lesions. CONCLUSIONS: Agreement between pseudocontinuous arterial spin-labeling and bookend technique CBF measurements is demonstrated in healthy controls and patients with relapsing-remitting MS. PMID- 27686493 TI - Causes of hepatic capsular retraction: a pictorial essay. AB - : Hepatic capsular retraction refers to the loss of the normal convex hepatic contour, with the formation of an area of flattening or concavity. This can result from myriad causes, including intrinsic hepatic conditions such as cirrhosis, biliary obstruction, benign tumours, malignancy and infections, as well as extrahepatic causes such as trauma. This article aims to provide familiarity with this wide spectrum of conditions, including mimics of hepatic capsular retraction, by highlighting the anatomic, pathologic and imaging features that help distinguish these entities from one another. TEACHING POINTS: * Hepatic capsular retraction can occur due to various intrinsic or extrinsic hepatic causes. * Hepatic capsular retraction is observed in both benign and malignant conditions. * Recognising associated imaging features can help elicit causes of hepatic capsular retraction. PMID- 27686494 TI - Chronic administration of [Pyr1] apelin-13 attenuates neuropathic pain after compression spinal cord injury in rats. AB - Apelin is an endogenous ligand for apelin receptor (APJ) with analgesic effect on visceral, analgesic and proanalgesic influences on acute pains in animal models. The purpose of this study was to determine the possible analgesic effects of [Pyr1] apelin-13 on chronic pain after spinal cord injury (SCI) in rats. Animals were randomly divided into three major groups as intact, sham and SCI. The SCI group randomly allocated to four subgroups as no treatment, vehicle-treatment (normal saline: 10MUl, intrathecally) and two subgroups with intrathecal injection (i.t) of 1MUg and 5MUg of [Pyr1] apelin-13. After laminectomy at T6-T8 level, spinal cord compression injury was induced using an aneurysm clip. Vehicle or [Pyr1] apelin-13 injected from day1 post SCI and continued for a week on a daily basis. Pain behaviors and locomotor activity were monitored up to 8weeks. At the end of the experiments, intracardial paraformaldehyde perfusion was made under deep anesthesia in some animals for histological and immunohistochemistry evaluations. Western blot technique was also done to detect caspase-3 in fresh spinal cord tissues. SCI decreased nociceptive thresholds and locomotor scores. Administration of [Pyr1] apelin-13 (1MUg and 5MUg) improved locomotor activity and reduced pain symptoms, cavity size and caspase-3 levels. Results showed long term beneficial effects of [Pyr1] apelin-13 on neuropathic pain and locomotion. Therefore, we may suggest [Pyr1] apelin-13 as a new option for further neuropathic pain research and a suitable candidate for ensuing clinical trials in spinal cord injury arena. PMID- 27686492 TI - Protein glycosylation in cancers and its potential therapeutic applications in neuroblastoma. AB - Glycosylation is the most complex post-translational modification of proteins. Altered glycans on the tumor- and host-cell surface and in the tumor microenvironment have been identified to mediate critical events in cancer pathogenesis and progression. Tumor-associated glycan changes comprise increased branching of N-glycans, higher density of O-glycans, generation of truncated versions of normal counterparts, and generation of unusual forms of terminal structures arising from sialylation and fucosylation. The functional role of tumor-associated glycans (Tn, sTn, T, and sLea/x) is dependent on the interaction with lectins. Lectins are expressed on the surface of immune cells and endothelial cells or exist as extracellular matrix proteins and soluble adhesion molecules. Expression of tumor-associated glycans is involved in the dysregulation of glycogenes, which mainly comprise glycosyltransferases and glycosidases. Furthermore, genetic and epigenetic mechanisms on many glycogenes are associated with malignant transformation. With better understanding of all aspects of cancer-cell glycomics, many tumor-associated glycans have been utilized for diagnostic, prognostic, and therapeutic purposes. Glycan-based therapeutics has been applied to cancers from breast, lung, gastrointestinal system, melanomas, and lymphomas but rarely to neuroblastomas (NBs). The success of anti-disialoganglioside (GD2, a glycolipid antigen) antibodies sheds light on glycan-based therapies for NB and also suggests the possibility of protein glycosylation-based therapies for NB. This review summarizes our understanding of cancer glycobiology with a focus of how protein glycosylation and associated glycosyltransferases affect cellular behaviors and treatment outcome of various cancers, especially NB. Finally, we highlight potential applications of glycosylation in drug and cancer vaccine development for NB. PMID- 27686495 TI - Coexisting giant splenic artery and portal vein aneurysms leading to non cirrhotic portal hypertension: a case report. AB - BACKGROUND: Splenic artery aneurysms are the commonest visceral and third most common abdominal artery aneurysms, having a strong association with both pregnancy and multiparity. Here we report possibly the first case of a giant splenic artery aneurysm in association with a smaller portal vein aneurysm, in a woman who had never conceived, leading to non-cirrhotic portal hypertension. CASE PRESENTATION: A 40-year-old Pakistani Asian woman who had no evidence of liver cirrhosis presented in April 2016 for a diagnostic workup of ascites, massive splenomegaly, and pancytopenia. An abdominal ultrasound followed by computed tomography angiography showed a giant aneurysm in her splenic artery and another smaller one in her portal vein. She underwent splenectomy and excision of the splenic artery aneurysm. Surgical findings included a giant splenic artery aneurysm pressing on her portal vein and causing its aneurysmal dilatation. On her first review in July 2016, she was generally in good health, ascites had subsided, and her full blood count was normal. Her portal vein aneurysmal dilatation, which was presumed to be secondary to the pressure effect from the splenic artery aneurysm, had shrunken remarkably in size. CONCLUSION: A giant splenic artery aneurysm can cause non-cirrhotic portal hypertension and should be treated with splenectomy and aneurysmectomy. PMID- 27686496 TI - Transient Kinetic Analysis of ATP Hydrolysis by the CCT/TRiC Chaperonin. AB - The chaperonin-containing t-complex polypeptide 1 (CCT, also known as TRiC) assists protein folding in an ATP-dependent manner. CCT/TRiC was mixed rapidly with different concentrations of ATP, and the amount of phosphate formed upon ATP hydrolysis was measured as a function of time using the coumarin-labeled phosphate-binding protein method. Two burst phases were observed, followed by a lag phase and then a linear steady-state phase of ATP hydrolysis. The phases were assigned by (i) determining their dependence on ATP and K+ concentrations and (ii) by measuring their sensitivity to the mutation Gly345->Asp in subunit CCT4, which decreases cooperativity in ATP binding. The values of the observed rate constants corresponding to the burst phases are found to decrease with increasing ATP and K+ concentrations, thereby indicating that the apo state of CCT/TRiC is in equilibrium between several conformations and that "conformational selection" by ATP takes place before hydrolysis. The amplitude of the lag phase, which follows, decreases with increasing ATP concentrations, thus indicating that it reflects a transition between states with low affinity for ATP and a state with high affinity for ATP that is predominant under steady-state conditions. A kinetic model based on the data is suggested, in which CCT/TRiC is in equilibrium between a relatively large number of states that are distinguished kinetically, in agreement with its proposed sequential allosteric mechanism. PMID- 27686497 TI - The gender gap among school children in poor rural areas of western China: evidence from a multi-province dataset. AB - BACKGROUND: The gender gap remains a major impediment in the path towards equality and it is especially wide in low-income countries. Up to the early 2000s, many studies documented extensive inequalities in China: girls had poorer health, less nutrition and less education than their male counterparts. The goal of this study is to examine whether the gender gap persists, given that China is now making the transition into the ranks of upper-middle income countries. We consider educational outcomes, mental and physical health status, as well as non cognitive outcomes. METHODS: We draw on a dataset containing 69,565 observations constructed by combining data from 7 different school-level surveys spanning 5 provinces. The surveys were all conducted by the authors between 2008 and 2013 using uniform survey instruments and data collection protocols in randomly selected schools across western provinces in rural China. The sample children range in age from 9 to 14 years (with 79 % of the sample being aged 10 to 12). Our analysis compares rural girls with rural boys in terms of 13 different indicators. RESULTS: With the exception of anemia rates, the health outcomes of girls are equal to those of boys. Girls and boys are statistically identical in terms of weight-for-age, height-for-age, and prevalence of intestinal worm infections. Girls performed better than boys on five of six cognitive and educational performance indicators. Girls performed worse than boys on all mental health indicators. All estimates are robust to the inclusion of different age ranges, controlling for the level of household assets, ethnic minority status, as well as the addition of provincial dummies. CONCLUSIONS: Our findings suggest that with the exception of non-cognitive outcomes, anemia and standardized math test scores, the gender gap in our study areas in China appears to be diminishing. PMID- 27686498 TI - Relationship between birth weight and total cholesterol concentration in adulthood: A meta-analysis. AB - BACKGROUND: Although a substantial number of studies have investigated the relationship between birth weight and serum cholesterol later in life, the results vary extensively. The aim of this study was to explore the relationship between birth weight and total cholesterol concentration in adulthood. METHODS: We considered the results of several published observational studies that reported the association between birth weight and total cholesterol concentration in adulthood. The associations were assessed by linear regression coefficients. Summary regression coefficients with 95% confidence intervals (CI) were computed using random-effects models. Subgroup and sensitivity analyses were also conducted to explore possible explanations for heterogeneity among the studies. RESULTS: A total of 20 studies with 26,122 participants were identified. After adjustment for adult body mass index, the summary regression coefficient for an increment in birth weight of 1 kg was -0.09 mmol/L (95% CI: -0.13, -0.05) for men without heterogeneity (I2 = 17.2%) and -0.08 mmol/L (95% CI: -0.13, -0.03) for women with low heterogeneity (I2 = 34.0%). Stratified and sensitivity analyses generally confirmed the robustness of the findings in men. However, subgroup analyses by age indicated that the association of birth weight with total cholesterol was statistically significant only in women aged <50 years. There was no evidence of publication bias in these studies. CONCLUSION: Based on our results, lower birth weight was found to be associated with higher concentrations of total cholesterol in men aged >18 years and in women aged <50 years.

AB - BACKGROUND: The etiology of autism is complex, and may involve the interaction between genetic and environmental factors. Recent studies suggested an association between maternal immune response and this disorder. METHODS: Forty nine women with autistic children (cases) were studied in comparison with 73 women with normal children (controls). After interviewing for sociodemographic and clinical information, mothers' sera were tested for the presence of antineuronal antibodies. RESULTS: Mothers of autistic children had significantly higher seropositivity for anti-Yo antibodies (34.7%) than control women (13.7%), with an (adjusted odds ratio of 2.60 (95% confidence interval, 1.03-6.61; p=0.044). Similarly, women with autistic children showed significantly higher seropositivity for antiamphiphysin than the control group (40.8% vs. 17.8%), with an adjusted odds ratio of 2.54 (95% confidence interval, 1.07-6.04; p=0.035). No significant association was found between autism spectrum disorders and maternal anti-Hu antibodies and anti-Ri antibodies, and the history of autoimmune diseases. CONCLUSION: Some maternal antineuronal antibodies may contribute significantly to the risk of childhood autism. PMID- 27686500 TI - Verification of a formula developed to predict the postoperative intraocular pressure after cataract surgery in primary angle-closure glaucoma. AB - BACKGROUND: The aim of this study was to verify the accuracy of a formula predicting postoperative intraocular pressure (IOP) after phacoemulsification and intraocular lens implantation (PHCE-IOL) in primary angle-closure glaucoma (PACG). In a retrospective chart review of patients with PACG who underwent PHCE IOL between 2011 and 2014, we collected preoperative IOP, axial length, anterior chamber depth (ACD), number of pre-PHCE glaucoma medications, and IOP and glaucoma medications at 1 month and 3 months post-PHCE. METHODS: Post-PHCE IOP values at 1 month and 3 months were compared with those predicted using the formula: postoperative IOP = 6.354 + 0.186 pre-PHCE IOP * pre-PHCE ACD. Agreements between measured and predicted IOP values were analyzed using correlation coefficients and Bland-Altman plots. RESULTS: Of the 62 eyes included, the average pre-PHCE IOP was 19.47 +/- 5.84 mm Hg. Post-PHCE IOP values were 14.94 +/- 4.03 mm Hg at 1 month and 14.21 +/- 3.51 mm Hg at 3 months. Patients using more preoperative medications tended to show greater postoperative declines in medication usage. Predicted IOP significantly correlated with post PHCE IOP measured at 1 month (R = 0.314, p = 0.013) and 3 months (R = 0.325, p = 0.01). Bland-Altman plots of difference against average of measured and estimated IOP revealed two cases falling outside+/-1.96 standard deviation at 1 month, and five cases at 3 months, indicating good consistency between measurement and prediction. CONCLUSION: This formula was useful for predicting IOP at 1 month and 3 months after PHCE-IOL in PACG. It aids clinicians in preoperative assessment of whether PHCE-IOL alone is likely to achieve acceptable postoperative IOP control. PMID- 27686501 TI - Higher platelet counts are associated with metabolic syndrome independent of fatty liver diagnosis. AB - BACKGROUND: Platelet count (PC) and fatty liver are both associated with metabolic syndrome (MS), obesity, and type 2 diabetes. While PC increases in obesity and type 2 diabetes, the severity of hepatic fibrosis caused by fatty liver reduces PC. We aimed to investigate the correlation of PC and MS in patients with and without fatty liver. METHODS: We enrolled consecutive patients who received health check-ups at Taipei Veterans General Hospital from 2002 to 2009. Ultrasonography was used to diagnose fatty liver, and MS was diagnosed according to the criteria defined by the International Diabetes Federation Task Force on Epidemiology and Prevention. RESULTS: Among the 29,797 patients, MS was present in 28.74%. Higher PC was correlated with MS using multivariate analysis, while fatty liver had the strongest association with MS. After dividing the patients by the presence or absence of fatty liver, higher PC was still associated with MS in both groups. The patients were further stratified by age and gender, and MS was correlated with PC among all age groups in women and in men under 60 years of age; however, the association between PC and MS did not reach statistical difference in men older than 60 years. CONCLUSION: There is a significant correlation between PC and MS, and the correlation exists independent of gender, age, and fatty liver. PC may act as a surrogate marker for MS, and physicians should be concerned with the presence of MS among patients with high PC. PMID- 27686502 TI - Does intrauterine insemination timing matter for achieving pregnancy during ovulation induction using gonadotropins? A retrospective cohort study. AB - BACKGROUND: Intrauterine insemination (IUI) is a commonly used procedure to increase the infertile couples' chance of pregnancy. Single or double insemination and different timing choices are modifications of this intervention. The aim of this study was to elucidate the effect of the IUI procedure on clinical pregnancy rates when performed at 24 hours or 36 hours after ovulation triggered by human chorionic gonadotropin (hCG) following ovulation induction with gonadotropins. METHODS: One hundred and thirteen women diagnosed with polycystic ovarian syndrome (PCOS) (as per Rotterdam's criteria) or unexplained infertility, who were treated using gonadotropins for ovulation induction and IUI for increasing fertilization potential, were recruited from the medical records of the infertility clinic. Demographic features, cycle outcomes, and clinical pregnancy rates of the patients were compared based on two different timing strategies of IUI (24 hours and 36 hours) following ovulation trigger using hCG. RESULTS: Clinical pregnancy rates per cycle were 22.9% in the PCOS group and 26.9% in the unexplained group. The clinical pregnancy rates according to the timing of IUI were found to be similar for PCOS patients, unlike patients with unexplained infertility whose clinical pregnancy rates were significantly better when the IUI procedure was performed 24 hours following the hCG trigger. The cycle day of hCG trigger was also found to be significantly related to clinical pregnancy rate as utilizing a later hCG trigger day appeared to positively affect the odds of clinical pregnancy establishment. CONCLUSION: IUI performed at either 24 hours or 36 hours after ovulation triggered by hCG injection does not change clinical pregnancy rates for PCOS patients. Patients with unexplained infertility seem to benefit from earlier IUI procedures, which increases their fertility potential during ovulation induction with gonadotropins. Avoiding earlier than physiologically needed artificial-hCG triggering before IUI procedures results with better pregnancy rates. PMID- 27686503 TI - December 2016, Editor-in-Chief Letter. PMID- 27686504 TI - Intraventricular Meningiomas: A Series of 42 Patients at a Single Institution and Literature Review. AB - BACKGROUND: Primary intraventricular meningiomas (IVMs) make up 0.5%-5% of all intracranial meningiomas and represent one of the most challenging lesions in neurosurgery. METHODS: Between 1990 and 2013, 42 patients (30 female, 12 male; mean age, 43.6 years) underwent resection of their IVM. The removal was performed by a posterior parietal approach in 19 of the 40 lateral ventricle tumors, and 1 third ventricle meningioma. The transcallosal approach was used for 3 meningiomas, and patients with other lesions underwent temporal (7 cases) and temporoparietal approaches (12 patients), respectively. RESULTS: The most common presenting signs were increased intracranial pressure (83.3%), visual impairment (78.6%) and cognitive changes (50%). Forty lesions (95.2%) arose in the lateral ventricles, and 2 (4.8%) in the third ventricle, ranging in size from 3 to 10 cm. Total removal was achieved in 39 cases and the pathology report disclosed World Health Organization grade I lesions in 41 cases. Hydrocephalus, cerebrospinal fluid leakage, and cerebral edema were the postoperative complications (7.15%); 1 patient died of respiratory problems not directly related to surgery. Thirty-five patients (83.3%) showed a 6-month Glasgow Outcome Scale of 5. One patient, who underwent partial resection, presented a recurrence after 1 year that remained stable until last follow-up. CONCLUSIONS: IVMs usually reach a large size before being diagnosed. Surgical treatment is the most suitable option and total removal should represent the main goal of the procedure. The posterior parietal transulcal approach and the temporoparietal approach are the most common surgical routes used in our series. PMID- 27686505 TI - Fatal Superior Sagittal Sinus and Torcular Thrombosis After Vestibular Schwannoma Surgery: Report of a Rare Complication and Review of the Literature. AB - BACKGROUND: Cerebral venous sinus thrombosis (CVST) is a rare condition with the potential to cause severe morbidity and mortality. CVST can also occur after vestibular schwannoma (VS) surgery with the thrombosis of transverse and sigmoid sinus. However, there is not a single report of superior sagittal sinus (SSS) thrombosis after VS surgery reported in the literature. CASE DESCRIPTION: A 45 year-old woman presented to our center with large left-sided solid cystic VS. On admission she was dehydrated, and after clinical stabilization, she underwent gross total excision of tumor through left retromastoid suboccipital craniotomy after cerebrospinal fluid drainage through an external ventricular drain. Surgery was uneventful, but postoperatively she had an episode of seizure. Immediate postoperative computed tomography (CT) brain scan was normal with good operative cavity. However, 24 hours later, she developed left-sided motor deficit, and a repeat CT scan showed right frontal parenchymal hemorrhage with intraventricular extension. On further evaluation, magnetic resonance venography showed entire SSS thrombosis, with patent bilateral transverse and sigmoid sinuses. She was not started on the anticoagulants in view of intracranial hemorrhage. Subsequently, she underwent right-sided decompressive craniectomy because there was progressive deterioration in her Glasgow Coma Scale, and she succumbed despite all efforts. Retrospectively, dehydration and intracranial hypotension could be likened to her sinus thrombosis. CONCLUSIONS: This case underscores the significance of adequate optimization of the patients prior to surgery, besides adequate operative skills to avoid this rare but serious complication of SSS and torcular thrombosis after VS surgery. PMID- 27686506 TI - Clinical Impact and Implication of Real-Time Oscillation Analysis for Language Mapping. AB - BACKGROUND: We developed a functional brain analysis system that enabled us to perform real-time task-related electrocorticography (ECoG) and evaluated its potential in clinical practice. We hypothesized that high gamma activity (HGA) mapping would provide better spatial and temporal resolution with high signal-to noise ratios. METHODS: Seven awake craniotomy patients were evaluated. ECoG was recorded during language tasks using subdural grids, and HGA (60-170 Hz) maps were obtained in real time. The patients also underwent electrocortical stimulation (ECS) mapping to validate the suspected functional locations on HGA mapping. The results were compared and calculated to assess the sensitivity and specificity of HGA mapping. For reference, bedside HGA-ECS mapping was performed in 5 epilepsy patients. RESULTS: HGA mapping demonstrated functional brain areas in real time and was comparable with ECS mapping. Sensitivity and specificity for the language area were 90.1% +/- 11.2% and 90.0% +/- 4.2%, respectively. Most HGA positive areas were consistent with ECS-positive regions in both groups, and there were no statistical between-group differences. CONCLUSIONS: Although this study included a small number of subjects, it showed real-time HGA mapping with the same setting and tasks under different conditions. This study demonstrates the clinical feasibility of real-time HGA mapping. Real-time HGA mapping enabled simple and rapid detection of language functional areas in awake craniotomy. The mapping results were highly accurate, although the mapping environment was noisy. Further studies of HGA mapping may provide the potential to elaborate complex brain functions and networks. PMID- 27686507 TI - Benign Glandular Schwannoma in Basal Ganglia. AB - BACKGROUND: The oncogenesis and biologic behaviors of benign glandular schwannoma have not been clinically unveiled because of its rarity and variability. CASE DESCRIPTION: However, we report a young male patient who presented with a benign glandular schwannoma in the basal ganglia, a site that has not been reported in any literature. Histologically, the samples are composed of spindle-shaped cells and variable glandular structures. The spindle-shaped cells are identified with the appearance of Antoni A and Antoni B zones. Moreover, the glandular structures are lined by stratified epithelial cells, glandular epithelium cells, intestinal epithelial cells, and few degenerative syncytial macrophage cells. Hemorrhage, necrosis and cystic changes were observed in the specimen cells, but no mitotic figures were found. The immunohistochemical results showed that the spindle cells were stained with S-100 protein, but lacked carcinoembryonic antigen (CEA), cytokeratin pan (AE1/AE3) (CK), synaptophysin, chromogranin A, and glial fibrillary acidic protein reactivity after surgery. Meanwhile, the glandular epithelium cells mostly consisted of glandular epithelium and stratified epithelium cells stained with CEA, chromogranin A, and CK antigen. CONCLUSIONS: Therefore, the morphologic and immunohistochemical findings support the diagnosis of benign glandular schwannoma. PMID- 27686508 TI - Risk of Infection After Local Field Potential Recording from Externalized Deep Brain Stimulation Leads in Parkinson's Disease. AB - OBJECTIVE: Adaptive deep brain stimulation (aDBS) controlled by local field potentials (LFPs) is considered a promising treatment for advanced Parkinson's disease (PD). The clinical research investigating aDBS functioning is performed using external deep brain stimulation (DBS) systems that require LFP recording through the temporary externalization of DBS leads. Although research examining LFP was first undertaken more than 20 years ago, only a few studies concern lead externalization and LFP recording safety. In the present retrospective study, we assessed the risk of infection related to these procedures. METHODS: A total of 105 patients with PD who underwent DBS surgery and lead externalization at our hospital from 2002 to 2014 were included in the present study. The medical records were used to collect clinical data and information concerning surgical site infections. We assessed the infection incidence in our cohort and the risk of infection related to the LFP recording procedure. RESULTS: The incidence of infections in patients who underwent lead externalization was 2.8%, which was consistent with the postoperative infectious risk reported in the literature (Wilcoxon signed rank test; P > 0.05). Moreover, the LFP recording procedure did not significantly increase the infection risk (LFP recordings vs. no LFP recordings: 2.5% vs. 4.2%; Fisher exact test; P > 0.05). CONCLUSIONS: DBS lead externalization and LFP recording are safe and do not increase the postoperative infection risk in patients with PD who undergo DBS surgery. Our retrospective study supported further clinical research in the field of LFP-based aDBS. PMID- 27686510 TI - The safety and efficacy of ramucirumab in combination with docetaxel in the treatment of lung cancer. AB - INTRODUCTION: Angiogenesis is critical for tumor growth, proliferation and metastasis with the crucial role of Vascular Endothelial Growth factor (VEGF) pathway. Ramucirumab is a monoclonal antibody that specifically targets the extracellular domain of Vascular Endothelial Growth Factor Receptor 2. Areas covered: We performed a search on Medline to browse the current literature on Ramucirumab and anti-angiogenic agents, for the treatment of NSCLC. The REVEL study demonstrated a significant improvement of response rate, progression-free survival and overall survival by adding ramucirumab to docetaxel compared to docetaxel plus a placebo in second-line treatment of advanced non-small cell lung cancer, irrespective of histology, with an acceptable safety profile. This article has for objective to summarize efficacy and safety data of the use of ramucirumab in combination with docetaxel in second line in NSCLC. Expert commentary: REVEL constitutes the first significant advance in second-line setting for patients eligible to anti-angiogenic therapy. The landscape of post platinum therapy in NSCLC is considerably evolving and the role of ramucirumab or other anti-angiogenic agents as nintedanib in this setting has to be discussed for each patient with other available treatment options, among which immune checkpoints inhibitors, as well as the best treatment sequence. PMID- 27686509 TI - Influence of Body Mass Index on Subjective and Objective Measures of Pain, Functional Impairment, and Health-Related Quality of Life in Lumbar Degenerative Disc Disease. AB - OBJECTIVE: To analyze the influence of body mass index (BMI) on subjective and objective measures of pain, functional impairment, and health-related quality of life in patients with lumbar degenerative disc disease undergoing surgery. METHODS: Prospective institutional review board-approved 2-center study, measuring visual analog scale (VAS) back and leg pain, Roland-Morris Disability Index (RMDI), Oswestry Disability Index (ODI), EuroQol 5D questionnaire, and Short Form-12 at baseline, 6 weeks, 6 months, and 1 year postoperatively. T scores of objective functional impairment (OFI) were determined using the Timed Up and Go (TUG) test. RESULTS: A total of 375 patients with a median BMI of 26.6 kg/m2 (94 obese patients [BMI >=30 kg/m2]) were included. Obese patients presented more VAS back pain (mean, 4.7 vs. 3.6; P = 0.001) and greater disability on the RMDI (mean, 12.6 vs. 11.3; P = 0.045). The prevalence and severity of OFI were similar in obese and nonobese patients. There was a weak positive correlation between BMI and VAS back pain (r = 0.1552; P = 0.0026), on both RMDI (r = 0.1138; P = 0.0276) and ODI (r = 0.1075; P = 0.0374). There was no correlation between BMI and TUG T-scores (r = 0.0475; P = 0.3585). Obese patients were as likely as nonobese patients to show a positive 6-week treatment response, and the outcome up to 1 year was similar. CONCLUSIONS: BMI positively correlates with VAS back pain, RMDI, and ODI. Standardized TUG T scores reflect the patient's degree of OFI well, irrespective of BMI. The TUG test appears to be a good means to estimate functional impairment in populations with a high prevalence of obesity. PMID- 27686511 TI - Insufficient developmental excitatory neuronal activity fails to foster establishment of normal levels of inhibitory neuronal activity. AB - The nervous system is composed of excitatory and inhibitory neurons. One major class of inhibitory neurons release the neurotransmitter gamma-Aminobutyric acid (GABA). GABAergic inhibitory activity maintains the balance that is disrupted in conditions such as epilepsy. At least some GABAergic neurons are initially excitatory and undergo a developmental conversion to convert to inhibitory neurons. The mechanism(s) behind this conversion are thought to include a critical developmental increase in excitatory activity. To test this hypothesis, we subjected ex vivo developing neuronal networks on multi-electrode arrays to various stimulation and pharmacological regimens. Synaptic activity of networks initially consists of epileptiform-like high-amplitude individual "spikes", which convert to organized bursts of activity over the course of approximately 1 month. Stimulation of networks with a digitized synaptic signal for 5days hastened the decrease of epileptiform activity. By contrast, stimulation for a single day delayed the appearance of bursts and instead increased epileptiform signaling. GABA treatment reduced total signals in unstimulated networks and networks stimulated for 5days, but instead increased signaling in networks stimulated for 1day. This increase was prevented by co-treatment with (2R)-amino-5 phosphonopentanoate and 6-cyano-7-nitroquinoxaline-2,3-dione, confirming that GABA invoked excitatory activity in networks stimulated for 1day. Glutamate increased signals in networks subjected to all stimulation regimens; the GABA receptor antagonist bicuculline prevented this increase only in networks stimulated for 1day. These latter findings are consistent with the induction of so-called "mixed" synapses (which release a combination of excitatory and inhibitory neurotransmitters) in networks stimulated for 1day, and support the hypothesis that a critical level of excitatory activity fosters the developmental transition of GABAergic neurons from excitatory to inhibitory. PMID- 27686512 TI - Assessment of Perioperative Ultrasound Workflow Understanding: A Consensus. AB - OBJECTIVES: Understanding of the workflow of perioperative ultrasound (US) examination is an integral component of proficiency. Workflow consists of the practical steps prior to executing an US examination (eg, equipment operation). Whereas other proficiency components (ie, cognitive knowledge and manual dexterity) can be tested, workflow understanding is difficult to define and assess due to its contextual and institution-specific nature. The objective was to define the workflow components of specific perioperative US applications using an iterative process to reach a consensus opinion. DESIGN: Expert consensus, survey study. SETTING: Tertiary university hospital. PARTICIPANTS: This study sought expert consensus among a focus group of 9 members of an anesthesia department with experience in perioperative US. Afterward, 257 anesthesia faculty members from 133 academic centers across the United States were surveyed. INTERVENTIONS: A preliminary list of tasks was designed to establish the expectations of workflow understanding by an anesthesiology resident prior to clinical exposure to perioperative US. This list was modified by a focus group through an iterative process. Afterwards, a survey was sent to faculty members nationwide, and Likert scale ratings for each task were obtained and reviewed during a second round. MEASUREMENTS AND MAIN RESULTS: Consensus among members of the focus group was reached after 2 iterations. 72 participants responded to the nationwide survey (28%), and consensus was reached after the second round (Cronbach's alpha = 0.99, ICC = 0.99) on a final list of 46 workflow-related tasks. CONCLUSIONS: Specific components of perioperative US workflow were identified. Evaluation of workflow understanding may be combined with cognitive knowledge and manual dexterity testing for assessing proficiency in perioperative US. PMID- 27686513 TI - Mobile Extracorporeal Membrane Oxygenation Teams: The North American Versus the European Experience. AB - OBJECTIVE: To evaluate differences in the inclusion of anesthesiologists in mobile extracorporeal membrane oxygenation (ECMO) teams between North American and European centers. DESIGN: A retrospective review of North American versus European mobile ECMO teams. The search terms used to identify relevant articles were the following: "extracorporeal membrane transport," "mobile ECMO," and "interhospital transport." SETTING: MEDLINE review of articles. PARTICIPANTS: None. INTERVENTIONS: None. RESULTS: Between 1986 and 2015, 25 articles were published that reported the personnel makeup of mobile ECMO teams in North America and Europe: 6 from North American centers and 19 from European centers. The included articles reported a total of 1,329 cases: 389 (29%) adult-only cohorts and 940 (71%) mixed-age cohorts. Among North American studies, 0 of 6 (0%) reported the presence of an anesthesiologist on the mobile ECMO team in contrast to European studies, in which 10 of 19 (53%) reported the inclusion of an anesthesiologist (Fisher exact p for difference = 0.05). In terms of number of cases, this discrepancy translated to 543 total cases in North America (all without an anesthesiologist) and 499 cases in Europe (37%) including an anesthesiologist on the team (Fisher exact p for difference<0.001). CONCLUSIONS: This study demonstrated significant geographic discrepancies in the inclusion of anesthesiologists on mobile ECMO teams, with European centers more likely to incorporate an anesthesiologist into the mobile ECMO process compared with North American centers. PMID- 27686514 TI - Preparation of protein nano-objects by assembly of polymer-grafted proteins. AB - We carried out surface-grafting from proteins and their assembling into objects with unique nanostructured materials (nano-objects). To immobilize polymer initiating sites, amino groups of bovine serum albumin (BSA) were allowed to react with iniferter groups (BSA-i). Then, graft polymerization of N-isopropyl acrylamide (NIPAM) was performed by light-initiated living radical polymerization from immobilized iniferter moieties of BSA-i. The polymer-grafted BSA (BSA-g PNIPAM) was assembled into nano-objects through the precipitation of PNIPAM graft chains and their sizes and morphologies were tuned by the chain length, the density and the chemical structure of graft polymers in addition to the environmental conditions such as temperature and pH. It was possible to retain the structures of nano-objects by thermal denaturation via heat treatment. Fluorescent substances were encapsulated in particulate nano-objects (nanoparticles) assembled from PNIPAM-g-BSA and their release could be regulated by tuning pH and temperature. Next, further graft polymerization from PNIPAM grafted BSA was carried out by living radical polymerization of a cationic monomer, N,N-dimethylamino propyl acrylamide methyl chloride quaternary (DMAPAAQ). The grafted polymer was composed of a block copolymer of PNIPAM and a cationic polymer (PDMAPAAQ) and the gel-like nano-object was generated by increasing temperature. In contrast to PNIPAM-g-BSA, it became insoluble even when the temperature decreased, probably due to the electrostatic association between anionic regions of BSA and cationic regions of graft polymers. Coating of BSA-g-P(NIPAM-b-DMAPAAQ) enabled to form a uniform thin layer over a human hair. A free-standing membrane could be obtained by peeling from a water repellent substrate to create a porous membrane. PMID- 27686515 TI - Compression tests of Fusarium graminearum ascocarps provide insights into the strength of the perithecial wall and the quantity of ascospores. AB - The plant pathogenic ascomycete Fusarium graminearum produces perithecia on corn and small grain residues. These perithecia forcibly discharge ascospores into the atmosphere. Little is known about the relationship among the strength of the perithecial wall, the age of the perithecium, and the quantity of ascospores produced. We used a mechanical compression testing instrument to examine the structural failure rate of perithecial walls from three different strains of F. graminearum (two wild type strains, and a mutant strain unable to produce asci). The force required to compress a perithecium by one micrometer (the mean perithecium compression constant, MPCC) was used to determine the strength of the perithecial wall. Over the course of perithecial maturation (5-12days after the initiation of perithecial development), the MPCC was compared to the number of ascospores contained inside the perithecia. The MPCC increased as perithecia matured, from 0.06NMUm-1 at 5d to 0.12NMUm-1 at 12d. The highest number of ascospores was found in older perithecia (12d). The results indicated that for every additional day of perithecial aging, the perithecia become more resilient to compression forces. Every additional day of perithecial aging resulted in ~900 more ascospores. Knowledge of how perithecia respond to external forces may provide insight into the development of ascospores and the accumulation of turgor pressure. In the future, compression testing may provide a unique method of determining perithecial age in the field, which could extend to management practices that are informed by knowledge of ascospore release and dispersal. PMID- 27686516 TI - The association between location, age and advanced colorectal adenoma characteristics: a propensity-matched analysis. AB - PURPOSE: Evidence supports an association between certain colorectal adenoma characteristics and predisposition to cancer. The association between anatomical location of colorectal adenoma, age and advanced adenomas needs attention. The objective of this study was to evaluate the possible association between occurrence of sporadic advanced adenomas with location and age. MATERIALS AND METHODS: A cross-sectional study using baseline data from index colonoscopy from a randomized controlled trial evaluating chemopreventive treatment against recurrence of colorectal adenomas was performed. Inclusion criteria for patients were one adenoma of >1 cm in diameter or multiple adenomas of any size, or an adenoma of any size and familial disposition for colorectal cancer. Multivariate regression and propensity score-matched analyses were used to correlate location of adenomas and age with advanced adenoma features. RESULTS: In this study, 2149 adenomas were removed in 1215 patients. Advanced colorectal adenomas primarily occurred in the anal part of the colon. Older age was associated with more adenomas and more oral occurrence of adenomas, as well as a higher risk of advanced adenomas. Surprisingly, specifically for the oral adenomas the risk of advanced adenoma seems to be lower for older patients compared with younger. CONCLUSIONS: This study presents new results with regard to association between age, location of adenomas and risk of advanced adenomas. The results indicate that sigmoidoscopy for screening purposes may be obsolete, and add to the existing literature on which future guidelines for screening may be based. PMID- 27686517 TI - A case of recent myocardial infarction with cardiac failure. AB - CLINICAL INTRODUCTION: A 50-year-old hypertensive smoker presented with a typical angina of 2 days duration. An urgent ECG revealed extensive anterior wall myocardial infarction. In view of the delayed presentation, the patient was conservatively managed with heparin. In-hospital echocardiogram showed akinesia of entire left anterior descending artery (LAD) territory with severe left ventricular (LV) dysfunction. He was discharged with a plan for early coronary intervention. However, he presented a fortnight later with acute pulmonary oedema. General appraisal revealed a restless individual who was dyspnoeic and diaphoretic at rest. On clinical examination, the patient was in hypotension with features of biventricular failure. A 12-lead ECG showed QS pattern with persistent ST segment elevation in precordial leads. The chest radiograph demonstrated features of pulmonary oedema, cardiomegaly and bilateral pleural effusion. Creatine Phosphokinase-MB (CPK-MB) was negative. A preliminary transthoracic echocardiography was done (figure 1 and see online supplementary video 1). QUESTION: What is the most likely diagnosis based on the echocardiogram? LV pseudo-aneurysm with contained ruptureDissecting intramural haematoma of LV apexVentricular apical aneurysm with thrombusLV non-compaction with prominent ventricular trabaculations. PMID- 27686518 TI - The long and unfinished journey of hyperglycaemia and heart failure research. PMID- 27686519 TI - Influenza vaccine as a coronary intervention for prevention of myocardial infarction. AB - Cardiovascular disease (CVD) is the leading cause of morbidity and mortality globally. Influenza is one of the leading infectious causes of morbidity and mortality globally, and evidence is accumulating that it can precipitate acute myocardial infarction (AMI). This is thought to be due to a range of factors including inflammatory release of cytokines, disruption of atherosclerotic plaques and thrombogenesis, which may acutely occlude a coronary artery. There is a large body of observational and clinical trial evidence that shows that influenza vaccine protects against AMI. Estimates of the efficacy of influenza vaccine in preventing AMI range from 15% to 45%. This is a similar range of efficacy compared with the accepted routine coronary prevention measures such as smoking cessation (32-43%), statins (19-30%) and antihypertensive therapy (17 25%). Influenza vaccine should be considered as an integral part of CVD management and prevention. While it is recommended in many guidelines for patients with CVD, rates of vaccination in risk groups aged <65 years are very low, in the range of 30%. The incorporation of vaccination into routine CVD prevention in patient care requires a clinical practice paradigm change. PMID- 27686520 TI - Optimisation of nutritional requirements for dopamine synthesis by calcium alginate-entrapped mutant strain of Aspergillus oryzae EMS-6. AB - The optimisation of nutritional requirements for dopamine (DA) synthesis by calcium alginate-entrapped mutant variant of Aspergillus oryzae EMS-6 using submerged fermentation technique was investigated. A total of 13 strains were isolated from soil. Isolate I-2 was selected as a better producer of DA and improved by exposing with ethyl methylsulphonate (EMS). EMS-6 was selected as it exhibited 43 MUg/mL DA activity. The mutant variable was further treated with low levels of l-cysteine HCl to make it resistant against diversion and environmental stress. The conidiospores of mutant variant were entrapped in calcium alginate beads for stable product formation. EMS-6 gave maximum DA activity (124 MUg/mL) when supplemented with 0.1% peptone and 0.2% sucrose, under optimised parameters viz. pH 3, temperature of 55 degrees C and incubation time of 70 min. The study involves the high profile of DA activity and is needed, as DA is capable to control numerous neurogenic disorders.

PMID- 27686522 TI - Association of rotavirus strains and severity of gastroenteritis in Indian children. AB - Rotavirus is the leading cause of severe and dehydrating diarrhea in children aged under 5 years. We undertook this hospital-based surveillance study to examine the possible relationship between the severity of diarrhea and the various G-group rotaviruses circulating in India. Stool samples (n = 2,051) were systematically collected from 4,711 children aged <5 years admitted with severe acute gastroenteritis to 12 medical school centers from April 2011 to July 2012. Rotavirus testing was undertaken using a commercially available enzyme immunoassay kit for the rotavirus VP6 antigen (Premier Rotaclone Qualitative ELISA). Rotavirus positive samples were genotyped for VP7 and VP4 antigens by reverse-transcription polymerase chain reaction at a central laboratory. Of the stool samples tested for rotavirus antigen, 541 (26.4%) were positive for VP6 antigen. Single serotype infections from 377 stool samples were compared in terms of gastroenteritis severity. Among those with G1 rotavirus infection, very severe diarrhea (Vesikari score >= 16) was reported in 59 (33.9%) children, severe diarrhea (Vesikari score 11-15) in 104 (59.8%), moderate (Vesikari score 6-10) and mild diarrhea (Vesikari score 0-5) in 11 (6.3%). Among those with G2 infection, very severe diarrhea was reported in 26 (27.4%) children, severe diarrhea in 46 (48.4%), and moderate and mild diarrhea in 23 (24.2 %). Among those with G9 infection, very severe diarrhea was reported in 47 (54.5%) children, severe diarrhea in 29 (33.6%), and moderate and mild diarrhea in 10 (11.9%). Among those with G12 infection, very severe diarrhea was reported in 9 (40.9%) children and severe diarrhea in 13 (59.1%). The results of this study indicate some association between rotavirus serotypes and severity of gastroenteritis. PMID- 27686523 TI - The second gamma-H2AX assay inter-comparison exercise carried out in the framework of the European biodosimetry network (RENEB). AB - PURPOSE: Within the EU RENEB project, seven laboratories have taken part in training and harmonisation activities to strengthen triage gamma-H2AX-based radiation exposure assessment. This has culminated in a second triage biodosimetry exercise. MATERIALS AND METHODS: Whole blood and separated lymphocyte samples were homogenously irradiated with 60Co gamma rays at 0.5, 2.5 (blind samples), 0 and 2 Gy (reference samples). Following post-exposure incubations of 4 and 24 h, 16 samples were shipped on ice packs to each partner. The samples were stained and scored for gamma-H2AX foci, using manual and/or automated fluorescence microscope scoring strategies. Dose estimates were obtained and used to assign triage categories to the samples. RESULTS: Average dose estimates across all the laboratories correlated well with true doses. The most accurate assignment of triage category was achieved by manual scoring of the 4-h blood and lymphocyte samples. Only three samples out of a total of 46 were miscategorized in a way that could have adversely effected the clinical management of a radiation casualty. CONCLUSIONS: This inter-comparison exercise has demonstrated that following a recent acute radiation exposure, the gamma-H2AX assay could be a useful triage tool that can be successfully applied across a network of laboratories. PMID- 27686524 TI - Renal cell carcinoma survival and body mass index: a dose-response meta-analysis reveals another potential paradox within a paradox. AB - BACKGROUND: In healthy subjects increasing body mass index (BMI) leads to greater mortality from a range of causes. Following onset of specific diseases, however, the reverse is often found: called the 'obesity paradox'. But we recently observed the phenomenon called the 'paradox within the paradox' for stroke patients. OBJECTIVE: The objective of our study was to examine the effect of each unit increase in BMI on renal cancer-specific survival (CSS), cancer-specific mortality, overall survival (OS) and overall mortality. DESIGN: Random-effects generalized least squares models for trend estimation were used to analyze the data. Eight studies, comprising of 8699 survivals of 10 512 renal cell carcinoma (RCC) patients met the inclusion criteria, including 5 on CSS and 3 on OS. RESULTS: The association of BMI with CSS and OS was non-linear (P<0.0001, P=0.004, respectively). We observed that CSS increased in relation to BMI, indicating that there was the obesity paradox in RCC. However, each unit increase in BMI over 25 was associated with decreased OS, indicating that RCC may also exhibit a paradox within the paradox. CONCLUSIONS: Inconsistent effects of increases in BMI on CSS and OS, as previously observed for stroke, creates a paradox (different directions of mortality for different causes) within the obesity paradox. PMID- 27686525 TI - An unconventional pathway for mitochondrial protein degradation. AB - Many vital metabolic pathways take place in mitochondria, but some of the associated processes generate toxic substances including reactive oxygen species that can damage proteins and DNA. Therefore, it is critical to maintain normally functioning mitochondria to achieve proper cellular homeostasis. Along these lines, mitochondrial dysfunction is associated with numerous diseases, and mitochondria quality control is essential for cell survival. The maintenance of functioning mitochondria is particularly important in aging cells, and there is a strong relationship between cellular aging and dysfunctional mitochondria. The best characterized pathway that is responsible for the elimination of damaged mitochondria is mitophagy, a selective type of autophagy. In yeast, mitophagy requires the mitochondrial protein Atg32 to serve as a receptor for recognition and sequestration by a phagophore. Although conventional mitophagy has been extensively studied, recent research suggests that an unconventional pathway, which is independent of Atg32, contributes to the removal of mitochondria. PMID- 27686528 TI - MicroRNA let-7f-5p Inhibits Porcine Reproductive and Respiratory Syndrome Virus by Targeting MYH9. AB - Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most important viral pathogens in the swine industry. Current antiviral strategies do not effectively prevent and control PRRSV. Recent reports show that microRNAs (miRNAs) play vital roles in viral infections by post transcriptionally regulating the expression of viral or host genes. Our previous research showed that non-muscle myosin heavy chain 9 (MYH9) is an essential factor for PRRSV infection. Using bioinformatic prediction and experimental verification, we demonstrate that MYH9 expression is regulated by the miRNA let-7f-5p, which binds to the MYH9 mRNA 3'UTR and may play an important role during PRRSV infection. To understand how let-7f-5p regulates PRRSV infection, we analyzed the expression pattern of both let-7f-5p and MYH9 in porcine alveolar macrophages (PAMs) after infection with either highly pathogenic PRRSV (HP-PRRSV) or classical type PRRSV (N-PRRSV) using a deep sequencing approach with quantitative real-time PCR validation. Our results showed that both HP-PRRSV and N-PRRSV infection reduced let-7f-5p expression while also inducing MYH9 expression. Furthermore, let-7f-5p significantly inhibited PRRSV replication through suppression of MYH9 expression. These findings not only provide new insights into the pathogenesis of PRRSV, but also suggest potential new antiviral strategies against PRRSV infection. PMID- 27686527 TI - Identification of DNA methylation changes associated with disease progression in subchondral bone with site-matched cartilage in knee osteoarthritis. AB - Subchondral bone plays a key role in the development of osteoarthritis, however, epigenetics of subchondral bone has not been extensively studied. In this study, we examined the genome-wide DNA methylation profiles of subchondral bone from three regions on tibial plateau representing disease progression using HumanMethylation450 BeadChip to identify progression associated DNA methylation alterations. Significant differential methylated probes (DMPs) and differential methylated genes (DMGs) were identified in the intermediate and late stages and during the transition from intermediate to late stage of OA in the subchondral bone. Over half of the DMPs were hyper-methylated. Genes associated with OA and bone remodeling were identified. DMGs were enriched in morphogenesis and development of skeletal system, and HOX transcription factors. Comparison of DMGs identified in subchondral bone and site-matched cartilage indicated that DNA methylation changes occurred earlier in subchondral bone and identified different methylation patterns at the late stage of OA. However, shared DMPs, DMGs and common pathways that implicated the tissue reparation were also identified. Methylation is one key mechanism to regulate the crosstalk between cartilage and subchondral bone. PMID- 27686526 TI - Proteome-wide identification of the endogenous ADP-ribosylome of mammalian cells and tissue. AB - Although protein ADP-ribosylation is involved in diverse biological processes, it has remained a challenge to identify ADP-ribose acceptor sites. Here, we present an experimental workflow for sensitive and unbiased analysis of endogenous ADP ribosylation sites, capable of detecting more than 900 modification sites in mammalian cells and mouse liver. In cells, we demonstrate that Lys residues, besides Glu, Asp and Arg residues, are the dominant in vivo targets of ADP ribosylation during oxidative stress. In normal liver tissue, we find Arg residues to be the predominant modification site. The cellular distribution and biological processes that involve ADP-ribosylated proteins are different in cultured cells and liver tissue, in the latter of which the majority of sites were found to be in cytosolic and mitochondrial protein networks primarily associated with metabolism. Collectively, we describe a robust methodology for the assessment of the role of ADP-ribosylation and ADP-ribosyltransferases in physiological and pathological states. PMID- 27686529 TI - Clinical trials of lasers for toenail onychomycosis: The implications of new regulatory guidance. AB - BACKGROUND: Despite the fact that lasers are presently indicated for the cosmetic outcome "temporary increase in clear nail", these devices are increasingly used to treat onychomycosis and particularly in patients who are unwilling or unable to take oral antifungal medication. The US Food and Drug Administration (FDA) recently issued draft guidance for medical device trials for onychomycosis. OBJECTIVE: This review evaluates the quality of laser trials for onychomycosis and compares the design guidelines for medical devices and antifungal drugs. METHOD: The PubMed database up to 29 May 2015 was searched for clinical studies of laser treatment for onychomycosis. RESULTS: The evidence demonstrating that lasers eradicate pathogenic fungi is limited and published laser trials suffer from limitations such as incomplete reporting of randomization and lack of stratified analyzes for fingernail/toenail data and infecting organisms. Differences in inclusion criteria and efficacy outcomes between drug and device guidelines may prevent the comparison of results from device and drug trials. CONCLUSION: We propose the standardization of device guidelines to match those of antifungal drug trials. Patients and physicians need to be aware of the capabilities and limitations of laser treatment for onychomycosis. PMID- 27686531 TI - An engineering approach to design of dextran microgels size fabricated by water/oil emulsification. AB - A correlation, based on fluid mechanics, has been investigated for the mean particle diameter of crosslinked dextran microgels (CDMs) prepared via a water/oil emulsification methodology conducted in a single-stirred vessel. To this end, non-dimensional correlations were developed to predict the mean particle size of CDMs as a function of Weber number, Reynolds number and viscosity number similar to ones introduced for liquid-liquid dispersions. Moreover, a Rosin-Rammler distribution function has been successfully applied to the microgel particle size distributions. The correlations were validated using experimentally obtained mean particle sizes for CDMs prepared at different stirring conditions. The validated correlation is especially applicable to medical and pharmaceutical applications where strict control on the mean particle size and size distribution of CDMs are extremely essential.

AB - E. coli of the phylogenetic group B2 harbouring Extra intestinal Pathogenic Escherichia coli (ExPEC) genes are frequently seen as colonizers of the intestine in patients with active ulcerative colitis (UC). In this study, we describe the influence of E. coli Nissle (EcN) B2 as add-on treatment to conventional therapies in patients with active UC. For this study one hundred active UC patients were randomized to ciprofloxacin or placebo for 1 week followed by EcN or placebo for 7 weeks. Stool samples were collected at weeks 0, 1, 8, 12, where E. coli were characterized and fecal calprotectin was measured. We showed that in the active UC patient group receiving Placebo/EcN, fewer patients reached remission, in comparison to the patient group receiving Placebo/placebo (p < 0.05). Active UC patients initially colonized with E. coli B2 had increased fecal calprotectin values and Colitis Activity Index scores in comparison to patients colonized with E. coli A and D (p < 0.05*). In conclusion, treatment of UC patients with E. coli Nissle (B2) does not promote clinical remission and active UC patients colonized with E. coli B2 have an increased intestinal inflammation. PMID- 27686532 TI - Gamma-H2AX upregulation caused by Wip1 deficiency increases depression-related cellular senescence in hippocampus. AB - The PP2C family member Wild-type p53-induced phosphatase 1 (Wip1) critically regulates DNA damage response (DDR) under stressful situations. In the present study, we investigated whether Wip1 expression was involved in the regulation of DDR-induced and depression-related cellular senescence in mouse hippocampus. We found that Wip1 gene knockout (KO) mice showed aberrant elevation of hippocampal cellular senescence and of gamma-H2AX activity, which is known as a biomarker of DDR and cellular senescence, indicating that the lack of Wip1-mediated gamma-H2AX dephosphorylation facilitates cellular senescence in hippocampus. Administration of the antidepressant fluoxetine had no significant effects on the increased depression-like behaviors, enriched cellular senescence, and aberrantly upregulated hippocampal gamma-H2AX activity in Wip1 KO mice. After wildtype C57BL/6 mice were exposed to the procedure of chronic unpredictable mild stress (CUMS), cellular senescence and gamma-H2AX activity in hippocampus were also elevated, accompanied by the suppression of Wip1 expression in hippocampus when compared to the control group without CUMS experience. These CUMS-induced symptoms were effectively prevented following fluoxetine administration in wildtype C57BL/6 mice, with the normalization of depression-like behaviors. Our data demonstrate that Wip1-mediated gamma-H2AX dephosphorylation may play an important role in the occurrence of depression-related cellular senescence. PMID- 27686533 TI - Ecosystem services sustainability in the Mediterranean Sea: assessment of status and trends using multiple modelling approaches. AB - Mediterranean ecosystems support important processes and functions that bring direct benefits to human society. Yet, marine ecosystem services are usually overlooked due to the challenges in identifying and quantifying them. This paper proposes the application of several biophysical and ecosystem modelling approaches to assess spatially and temporally the sustainable use and supply of selected marine ecosystem services. Such services include food provision, water purification, coastal protection, lifecycle maintenance and recreation, focusing on the Mediterranean region. Overall, our study found a higher number of decreasing than increasing trends in the natural capacity of the ecosystems to provide marine and coastal services, while in contrast the opposite was observed to be true for the realised flow of services to humans. Such a study paves the way towards an effective support for Blue Growth and the European maritime policies, although little attention is paid to the quantification of marine ecosystem services in this context. We identify a key challenge of integrating biophysical and socio-economic models as a necessary step to further this research. PMID- 27686534 TI - Sit-To-Stand Lift: Effects of Lifted Height on Weight Borne and Upper Extremity Strength Requirements. AB - To prevent back and shoulder injuries to nursing personnel, sit-to-stand lifts are used to transfer partial-weight-bearing patients with upper extremity strength. However, the weight-bearing capacity and upper extremity strength required of patients have not been defined. The objectives of this study were to determine: (a) the percentage of body weight borne by the patient when lifted to different heights in the lift and (b) whether a patient needs upper extremity strength. Nineteen healthy normal-weight volunteers (ages 19-39) were transferred from a hospital bed to a wheelchair using (a) a gait belt and (b) a sit-to-stand lift. With legs secured in the lift, participants were lifted to five different heights (knee angles 120-180 degrees) while holding and not holding the lift handles. Participants supported a greater percentage of body weight as they were lifted higher, increasing from 60% to almost 100% (p < .01). Holding the handles did not have an effect on weight borne overall. At low heights, slightly less weight was borne when not using the handles than with them, and no difference in weight borne was found at heights near standing (p < .01). All participants felt more comfortable and safer transferring from bed to wheelchair with the mechanical lift than with the gait belt (p < .01). Results are limited to normal weight patients but suggest that sit-stand lifts can be used in patients without upper extremity strength. Patients with limited weight-bearing capacity can be transferred by not raising them high in the lift. (c) 2016 Wiley Periodicals, Inc.

AB - Camelid nanobodies (Nbs) raised against the outward-facing conformer of a double Trp mutant of the lactose permease of Escherichia coli (LacY) stabilize the permease in outward-facing conformations. Isothermal titration calorimetry is applied herein to dissect the binding thermodynamics of two Nbs, one that markedly improves access to the sugar-binding site and another that dramatically increases the affinity for galactoside. The findings presented here show that both enthalpy and entropy contribute favorably to binding of the Nbs to wild-type (WT) LacY and that binding of Nb to double-Trp mutant G46W/G262W is driven by a greater enthalpy at an entropic penalty. Thermodynamic analyses support the interpretation that WT LacY is stabilized in outward-facing conformations like the double-Trp mutant with closure of the water-filled cytoplasmic cavity through conformational selection. The LacY conformational transition required for ligand binding is reflected by a favorable entropy increase. Molecular dynamics simulations further suggest that the entropy increase likely stems from release of immobilized water molecules primarily from the cytoplasmic cavity upon closure. PMID- 27686535 TI - Function of the SIRT3 mitochondrial deacetylase in cellular physiology, cancer, and neurodegenerative disease. AB - In mammals, seven members of the sirtuin protein family known as class III histone deacetylase have been identified for their characteristic features. These distinguished characteristics include the tissues where they are distributed or located, enzymatic activities, molecular functions, and involvement in diseases. Among the sirtuin members, SIRT3 has received much attention for its role in cancer genetics, aging, neurodegenerative disease, and stress resistance. SIRT3 controls energy demand during stress conditions such as fasting and exercise as well as metabolism through the deacetylation and acetylation of mitochondrial enzymes. SIRT3 is well known for its ability to eliminate reactive oxygen species and to prevent the development of cancerous cells or apoptosis. This review article provides a comprehensive review on numerous (noteworthy) molecular functions of SIRT3 and its effect on cancer cells and various diseases including Huntington's disease, amyotrophic lateral sclerosis, and Alzheimer's disease.

PMID- 27686538 TI - The effect of purmorphamine on differentiation of endometrial stem cells into osteoblast-like cells on collagen/hydroxyapatite scaffolds. AB - We assessed the effect of purmorphamine along with collagen/hydroxyapatite scaffold in inducing osteogenesis of human endometrial stem cells (hEnSCs). The adhesion, viability, proliferation, and differentiation of cells on scaffold were assayed with SEM, MTT, real time-PCR, and ALP assay, respectively. The results were shown good integration of cells with scaffold. Also, qRT-PCR of differentiated cells shows that osteoblast cell markers are expressed after 21d in 2D and scaffold groups while in the scaffold group the expression of these markers were higher than the 2D group. Based on our findings, collagen/hydroxyapatite scaffold with PMA has the potential role in osteogenic differentiation of hEnSCs. PMID- 27686541 TI - [Clinical application of multi-electrode synchronous radiofrequency ablation via switching controller for treating large hepatocellular carcinoma]. AB - Objective: To explore the preliminary clinical efficacy and safety of multi electrode synchronous radiofrequency ablation via switching controller for treating large hepatocellular carcinoma. Methods: A total of 20 patients with large hepatocellular carcinoma from minimally invasive Interventional department of Sun Yat-sen University Cancer Center were enrolled in this retrospective study from December 2013 to December 2014.The procedures were conducted with multi electrode synchronous radiofrequency ablation via switching controller under CT guidance.The necrosis rate of tumor was assessed by the following imaging examination.The single factor analysis of variance (ANOVA) was employed to compare the total bilirubin, albumin, renal function, blood coagulation function before and after ablation, to evaluate the safety of treatment. Result: Twenty patients with a total of 31 lesions accepted 23 times ablation procedures using multi-electrode synchronous radiofrequency ablation via switching controller.The recent evaluation after treatment was as followed: complete necrosis rate 51.6% (16/31), nearly complete necrosis rate 22.6% (7/31), partial necrosis rate 9.7% (3/31), treatment effectiveness rate (necrosis rate > 50%) 83.9%.The necrosis rate which was less than half volume of the tumor was only seen in 5 cases with huge hepatocellular carcinoma (16.1%). No dead cases appeared after ablation procedures.The patients' total bilirubin elevated moderately after ablation procedures and reversed to normal level after liver function protection treatment.There were no statistical differences of renal function and blood coagulation function before and after ablation.After ablation procedures, 5 cases (21.7%, 5/23) appeared fever, 6 cases (26.1%) with vomiting, only 3 cases (13.0%, 3/23) with moderately severe pain in 3 days after ablation and remitted after taking oral analgesics in one week. Conclusion: The clinical efficacy of multi electrode synchronous radiofrequency ablation via switching controller for large hepatocellular carcinoma is satisfactory with guaranteed security, which can be a choice for treating large hepatocellular carcinoma.

AB - Objective: To retrospectively investigate the clinical characteristics, risk factors of Cytomegalovirus (CMV) infection in patients with underlying rheumatic diseases. Methods: Clinical records of 263 rheumatic patients with or without CMV infection, hospitalized from March 2011 to June 2014 in Peking University People's Hospital, were analyzed.Clinical characteristics were summarized and compared in CMV positive and negative groups, to investigate the risk factors for CMV infection.Statistical analyses were conducted with SPSS 20.0 software. Results: A total of 62 rheumatic patients were found to have CMV infection, with 48 regarded as CMV viremia, 7 diagnosed as CMV pneumonia, while the remaining 7 suffered both CMV viremia and pneumonia.Eleven of 62 patients (17.7%) had a fatal outcome.Systemic lupus erythematosus (SLE) was the most commonly underlying disease (41.9%), followed by Sjogren syndrome (16.1%) and systemic vasculitis (12.9%). Lymphopenia and the reduction of CD4+ T lymphocytes, corticosteroids, cyclophosphamide (CTX) or mycophenolate mofetil (MMF), combined use of more than 2 immunosuppressants and other severe underlying infections as risk factors for CMV infection in rheumatic patients.Meanwhile, the total dose of CTX wasn't different significantly between CMV positive and negative groups.Multivariate analysis revealed that large or pulsed dose of corticosteroids, combined use of immunosuppressants, and severe underlying infections remained independent risk factors for CMV infection. Conclusions: Lymphocytes, particularly the CD4+ T subsets, might play a vital role in the regulation and control of CMV infection.Other underlying infections, undergoing large dose corticosteroids therapy or combined use of immunosuppressants could be the risk factors for CMV infection in rheumatic patients.

AB - Objective: To initially explore MRI features and its changing trends including of lung tumors after Argon-Helium cryoablation therapy, and enhance the recognition of MR findings of lung tumors postcryoablation. Methods: Twenty-three cases of patients with twenty six nodules of pulmonary malignance who received Argon Helium cryoablation therapy in Henan Cancer Hospital from July 2014 to January 2016 were enrolled.All patients underwent unenhanced and dynamic contrast enhanced MRI scans at pre-and 1-day, 1-week, 1-, 3-, 6-, 12-month postcryoablation. Two radiologists independently reviewed MRI images, signal intensity in the ablated zone on T1WI and T2WI were assessed by a 5-point scale.The changing trends of size and signal intensity with time were showed by time-maximum diameter and time-score curve.Time-signal intensity curves based on dynamic enhanced sequence were also performed. Results: Typical MRI findings includes: heterogeneous signal intensity on both T1WI and T2WI at 1-day postcryoablation(26/26, 100%). Hyper-intense on T1WI(22/26, 84.6%) and T2WI(17/26, 65.4%) with a hypo-intense rim at 1-week postcryoablation.Decreasing signal intensity on T1WI(17/26, 65.4%) and increasing signal intensity on T2WI(22/26, 84.6%) at 1-month.Signal intensity declined to the level of muscle on both T1WI(18/26, 69.2%) and T2WI(19/26, 73.1%) at 3-month, nineteen ablated zone turned into patchy shape(19/26, 73.1%). The maximum diameter was largest at 1-day and gradually shrunk with time. The mean score value toped at 1-week and gradually decreased. A straight line type without definite enhancement was found from 1-day to 1-month postcryoablation, an inflow curve with a mild delayed enhancement was seen from 3- to 12- month. Totally 4 recurrence (4/26, 15.4%) all occurred at 3-month and were lack of a complete hypo-intense rim at 1-week postcryoablation. Conclusion: MRI findings of lung tumors postcryoablation are characteristic, a complete hypo-intense rim at 1-week is helpful to determine further recurrence, 1-week to 3-month is an important period to observe significant change of the ablation zone, MRI is valuable in identifying the ablation zone and can reflect its evolution with time.

AB - Objective: To evaluate the clinical value of changes of maximum standardized uptake value (SUVmax) in series 18F-FDG PET/CT imaging before and after chemotherapy for non-small cell lung cancer. Methods: From July 2008 to July 2014, a total of 18 patients with pathological confirmed advanced NSCLC who received systemic chemotherapy were enrolled.18F-FDG PET/CT scans were performed before, 3-4 weeks after 2-4 cycles chemotherapy, 3-4 weeks after the end of chemotherapy for all patients, and added fourth scan for 3 patients 1 year later.The SUVmax of region of interesting was calculated.The histological diagnosis or clinical findings in a 36 months follow-up period served as the standard of control. Results: New metastases foci were found by 18F-FDG PET/CT scans before chemotherapy in 7 of 18 patients.The plans of chemotherapy for 5 patients were changed as therapeutic responses were evaluated according to changes of SUVmax.Targeted therapy was added for 2 patients after the end of chemotherapy.There was a statistically significant difference in outcome of survival analysis between patients performed PET/CT scans and non-performed (P<0.05). Conclusion: Changes of SUVmax in series 18F-FDG PET/CT imaging before and after chemotherapy could be used to evaluate therapeutic response and effectively predict survival in patients with advanced NSCLC.

AB - Objective: To investigate the different genotype and allele frequency distribution of ADAM33 gene T1, T2, V4, S2 sites Mongolian population, and discuss the relationship between ADAM33 gene polymorphism and bronchial asthma. Methods: From January 2014 to December 2015, a total of 180 cases of Mongolian patients with asthma were detected, compared with 186 cases of healthy Mongolian as controled and screening significant genes.Selected restriction fragment length polymorphism (PCR-RFLP) method to detected ADAM33 gene polymorphism.According to condition , the asthma group was divided into mild(n=83), medium group(n=47)and severe group(n=50). The distribution difference of different genotype and every genotype of V4 FEV1, eosinophils, IgE comparison were compared , and analysis their correlation. Results: In ADAM33 , the distribution of T1 sites (AA and AG genotypes) had statistical significance compared asthma group with control group(chi2=8.810, 8.294, P<0.05, OR=1.983, 0.500). The OR value of G allele was 0.580.The distribution of S2 site(CC genotype) had statistical significance(chi2=4.277, P<0.05), the OR value of G allele was 1.423.the distribution of V4 sites (GC and GG genotypes) had statistical significance between the two groups (chi2=7.880, 10.313, P<0.05), OR value was 0.459, 2.130, G allele OR value was 1.496.The distribution frequency difference of each genotype in V4 sites in mild, medium and severe group was statistically significant (chi2=16.049, P<0.05), and compared various genotypes of FEV1, IgE, the difference was statistically significant (P<0.05), for each genotype of T2 site in asthma group and the control group there was no statistically significant in the distribution (chi2=1.218, 0.248, 1.287, P>0.05). Conclusions: T1, V4, S2 locus polymorphism of ADAM33 gene may play a role in the Mongolian asthma population, and T2 locus polymorphism may has no relationship with Mongolian asthma patients.And the genotype polymorphism of V4 sites may be associated with asthma severity. PMID- 27686545 TI - [Correlation between post-stroke pneumonia and outcome in patients with acute brain infarction]. AB - Objective: To investigate the correlation between post-stroke pneumonia and outcome in patients with acute brain infarction. Methods: Consecutive acute cerebral infarction patients who were hospitalized in Department of Neurology, Jinan Military General Hospital were prospectively recruited from August 2010 to August 2014. The baseline data including age, sex, the National Institute of Health Stroke Scale (NIHSS) scores, type of Oxfordshire Community Stroke Project (OCSP: total anterior circulation infarct, partial anterior circulation infarct, posterior circulation infarct and lacunar infarct), fasting blood glucose etc. after admission were recorded. Post-stroke pneumonia was diagnosed by treating physician according to criteria for hospital-acquired pneumonia of the Centers for Disease Control and Prevention. Recovery was assessed by modified Rankin Scale (mRS) 180 days after stroke by telephone interview (mRS<=2 reflected good prognosis, and mRS>2 reflected unfavorable prognosis). Multinominal Logistic regression analysis, Kaplan-Meier curve and log rank test were used. Results: A total of 1 249 patients were enrolled, among them 173 patients were lost during follow-up. A total of 159 patients had post-stroke pneumonia, while 1 090 patients were without post-stroke. Compared with patients without post-stoke pneumonia, patients with post-stroke pneumonia were older (67+/-13 vs 63+/-12 years, P=0.000), more severe (NIHSS, 15(14) vs 4(4), P=0.000). Compared with patients without post-stoke pneumonia, more patients with post-stroke pneumonia suffered from heart failure (12.58% vs 3.40%, P=0.000), atrial fibrillation (26.42% vs 8.81%, P=0.000), myocardial infarction (10.06% vs 5.05%, P=0.016), recurrent brain infarction (30.19% vs 22.66%, P=0.045), total anterior circulation infarct type of OCSP (46.54% vs 19.63%, P=0.000), posterior circulation infarct of OCSP (39.62% vs 25.51%, P=0.001); more patients suffered from disorder of consciousness (60.38% vs 9.27%, P=0.000), dysphagia (34.59% vs 19.89%, P=0.000), vomiting (26.42% vs 8.81%, P=0.000), aphasia (35.85% vs 16.61%, P=0.000) since onset. The morbidity of post-stroke pneumonia among patients with unfavorable outcome (29.37%(111/378)) was significantly higher than that among patients with favorable outcome (3.73%(26/698)) (P=0.000). Post-stroke pneumonia was an independent prognostic factor for long-term unfavorable outcome (OR=2.414, 95%CI: 1.336-4.361, P=0.004) and long-term mortality (OR=2.132, 95%CI: 1.229 3.699, P=0.007). According Kaplan-Meier estimation, the cumulative 180 days survival of patients with post-stroke pneumonia was lower than those without post stroke pneumonia (62.04%(85/137) vs 93.29%(876/939)); Log-rank test: chi2=137.32, P=0.000. Conclusions: Acute brain infarction patients with post-stroke pneumonia are older, more severe; more suffering from heart failure, atrial fibrillation, myocardial infarction; more suffering from disorder of consciousness since onset. Post-stroke pneumonia is an independent prognostic factor for long-term unfavorable outcome and for long term mortality in patients with acute brain infarction.

AB - Objective: To investigate the effectiveness and advantage of improved microsurgery for fulminant hemorrhagic dilation of the fourth ventricle. Methods: The clinical data of 21 patients with fulminant hemorrhagic dilation of the fourth ventricle were analyzed retrospectively.All patients underwent hemorrhage evacuation and improved atlantooccipital decompression via middle suboccipital trans-cerebellar vermis approach, with preceding external ventricular drain. Results: One patient died of brainstem failure postoperative, and 20 patients were followed up from 6 to 17 months.There were 8 patients whose KPS exceeded 90, 6 patients whose KPS were 60 to 90, 4 patients whose KPS were 30 to 60, and two patients whose KPS were lower than 30.There was no recurrence of hydrocephalus and posterior fossa fluid. Conclusions: The improved microsurgery for fulminant hemorrhagic dilation of the fourth ventricle not only could effectively raise the success rate of salvage, but also greatly reduce postoperative complications compared with traditional mode.

AB - Objective: To compare the clinical efficacy of the direct anterior approach (DAA) and the posterolateral approach (PLA) for total hip arthroplasty (THA) in the lateral decubitus position. Methods: From July to December, 2014, 104 patients randomly divided into two equal groups of the DAA group and the PLA group underwent unilateral primary THA procedures.All procedures were performed by the same surgeon in the Department of Orthopaedics, the Affiliated Anhui Provincial Hospital of Anhui Medical University.General data, perioperative index, postoperative function and radiological evaluation were recorded and statistically analyzed. Results: The patients had an average follow-up of 14 (range, 10-16) months.No significant differences were detected with respect to the operation time, incision length, preoperative Hb concentration and transfusion rate between two groups (P> 0.05 for all comparisons). However, there were significant differences associated with the intraoperative bleeding, postoperative drainage and postoperative Hb concentration in the two groups(P<0.05 for all comparisons). The DAA group showed significant superior outcomes compared with the PLA group in the Harris hip scores [(83.6+/-7.1) vs (79.8+/-6.6), P<0.05], WOMAC[ (28.9+/-6.1) vs (36.1+/-6.9), P<0.001], and VAS pain scores[ (2.2+/-0.9) vs (2.9+/-1.1), P<0.05]at 1 month after surgery. No differences were seen between the study groups in the evaluation of radiography and the incidence of adverse event (P> 0.05 for all comparisons). Conclusions: Compared with the posterolateral approach, the present study shows the exciting results in patients underwent the DAA THA in the lateral decubitus position at early follow-up.The advantages of THA using the DAA include less operative trauma, alleviation of postoperative pain, and faster postoperative rehabilitation. It is a safe, reliable and effective surgery approach.

AB - Objective: To assess the pain control efficiency of continuous adductor canal block in total knee arthroplasty. Methods: From October to December 2015, patients with severe knee osteoarthritis undergoing primary unilateral TKA were observed clinically.All of the patients received ultrasound-guided continuous adductor canal block after surgery.NPRS Pain score in rest and activity at 2, 6, 12, 24, 48 h after surgery were collected, preoperative and postoperative quadriceps strength at 24, 48 h were analyzed. Opioids consumption and anesthesia related adverse effects were also recorded. Results: All of the patients were enrolled. Rest pain control was fairly good(1.8+/-1.5), (2.4+/-1.5), (2.7+/-1.3), (2.7+/-1.7), (2.3+/-1.4) score, but the patients were not satisfied with activity pain control(3.1+/-2.1), (3.1+/-2.1), (4.2+/-2.2), (4.7+/-2.5), (6.2+/-2.4) score. There were statistically differences comparing the NPRS in rest pain with the score in activity, except for the results between each other at 6 hours (P=0.252>0.05)after surgery.The results showed no significant differences comparing quadriceps strengthpreoperatively with 24, 48 h postoperatively by repeated measurements variance analysis.Eight patients acquired additional use of dolantin once (100 mg/per time) within 24 h and among them three patients acquired once dolantin during 24 to 48 h. Eleven patients complained nausea postoperatively, one reported vomiting and one experienced xerostomia. Conclusion: Ultrasound-guided continuous adductor canal block can reduce resting pain after TKA, but has a limited effect in activity pain control.Quadriceps strength had been spared after ACB, which might performearly benefits in rehabilitation. ACB-related complications need further observation to be defined. PMID- 27686549 TI - [The Study of relationship between fetal radius loss and chromosomal abnormality]. AB - Objective: To explore the relationship between fetal radius loss and chromosomal abnormalities.

Conclusion: Through a comparison between the chromosome and ultrasonic characteristics of fetuses who have absent radius, we had indicated the relationship of fetal radius deletion and chromosomal anomaly, improved the positive rate of chromosome invasion examination, and provided the reference for eugenics. PMID- 27686550 TI - [Comparison of radiofrequency catheter ablation for paroxysmal supraventricular tachycardia guided by three dimensional navigation with X-ray]. AB - Objective: To compare the therapeutic efficiency and safety of radiofrequency catheter ablation (RFCA) for paroxysmal ventricular tachycardia (PSVT) guided by three-dimensional navigation with X-ray. Methods: One hundred and seventy-six patients with PSVT hospitalized in Department of Cardiology, Zhejiang Provincial People's Hospital between January 2013 and December 2014 were enrolled in this study. RFCA was performed on 95 patients (Group A) guided by the three dimensional electric-field navigation system (NavX) and the procedures were done with the spatial localization method, unless X-ray was needed in some cases.Eighty-one patients (Group B) underwent RFCA guided by X-ray only.The success rate, complications, recurrence rate, operation time, and X-ray exposure were compared between the two groups. Results: The immediate success rate of operation was 100% in the 176 PSVT patients without complications.There were recurrences in 2 cases of Group A, while in 1 case of Group B. The average operation time in Group A was (97+/-20) min, while (91+/-26) min in Group B. The median X-ray fluoroscopy time was 3.0 min and radiation dose was 18.5 MUGym2 in Group A, which were significantly reduced compared with those in Group B (34.5 min, 167.3 MUGym2) (P<0.05). There was no significant difference in immediate procedure success rate, complications, recurrence, and operative time between this two groups (P>0.05). Conclusions: The RFCA for PSVT guided by three dimensional navigation is safe and feasible in the experienced electrophysiological center.Most patients suffer less or no X-ray radiation.

AB - Objective: To evaluate the level of lexiscan-induced blood-brain barrier opening of healthy rabbits via CT perfusion weighted imaging (PWI) scan. Methods: Between November 2014 and May 2015, thirty New Zealand white rabbits were randomly assigned into three groups: the experimental group A1 which received one injection of lexiscan(1 ml/kg); the experimental group A2 which received three times injection of lexiscan(total dose: 1.5 ml/kg), finished within 15 minutes; the control group B which was injected the same volume normal saline(1 ml/kg), after 30 minutes, CT PWI scan was performed. Then cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT) and permeability surface(PS) of the region of interest of each group were acquired and compared statistically. Five cases of each group were injected with 2% Evans blue intravenously posterior to imaging. After one hour of infusion, all the animals were killed. Their brains were examined for the determination of Evans blue distribution. Results: Both the values of CBF and CBV and the staining with Evans blue of the group A1(CBF: (89.88+/-2.21), (81.42+/-4.28) ml.(100 g)-1.min-1; CBV: (3.97+/-0.43), (3.66+/ 0.16) ml/g)and group A2 (CBF: (75.16+/-0.84), (63.66+/-7.21) ml.(100 g)-1.min-1; CBV: (4.07+/-0.01), (3.75+/-0.05) ml/g) were higher than those of the group B(CBF: (20.08+/-5.08), (14.58+/-8.62) ml.(100 g)-1.min-1; CBV: (0.85+/-0.04), (0.65+/-0.17) ml/g), the differences were all statistically significant (all P<0.01). While there was no statistically difference between group A1 and group A2(P>0.05). The value of PS of the group A2((22.43+/-8.09), (20.20+/-7.01)ml.(100 g)-1.min-1 )was higher than that of group A1((13.82+/-4.44), (10.12+/ 2.44)ml.(100 g)-1.min-1) and group B(0.00, 0.00)(the lowest one), the differences were all statistically significant(all P<0.01). The value of MTT of the group A1((2.50+/-0.82, 2.47+/-0.10) s) had no statistical difference with group A2 and group B, while the value of group A2((4.50+/-0.17), (4.72+/-0.15) s) was higher than that of group B((1.88+/-0.09), (1.99+/-0.00) s), the differences were all statistically significant (P<0.05). Conclusion: Changes in hemodynamics of lexiscan-induced blood-brain barrier opening can be monitored by CT PWI scan. When the total dose of lexiscan increasing, the level of the BBB opening is higher with significantly increased CBF, CBV, PS and MTT. PMID- 27686552 TI - [Effects of body mass index on blood pressure control rate in elderly coronary heart disease outpatients with hypertension]. AB - Objective: To explore the influences of body mass index (BMI) on blood pressure control rate in elderly coronary heart disease (CHD) outpatients with hypertension. Methods: In this multicenter, non-intervention and cross-sectional survey, the elderly coronary heart disease patients with hypertension aged 60 years or over were recruited from 165 hospitals in 21 provinces or cities across China from April to July 2011, and 5 140 cases of elderly CHD patients with hypertension were finally included into the study. The cases were divided into low BMI group (n=130 cases), normal body mass index (BMI) group (n=1 390 cases), overweight (n=2 418 cases), obesity group (n=662 cases) according to the different levels of BMI. Clinical data and blood pressure control rate were compared among the groups, and relationships of different BMI levels with blood pressure control rate were analyzed by the binary classification unconditioned Logistic regression equation. Results: There was a statistically significant difference in blood pressure control rate of general population, men and women patients among low BMI group, normal BMI group, overweight and obesity group (chi2=66.346, 58.995, 26.044, respectively, P<0.001), blood pressure failure rate in obesity group (73.7%) was higher than that in overweight group (65.8%) and normal BMI group (57.5%) (P<0.05), and overweight group was also higher than normal BMI group (P<0.05); blood pressure failure rate in obesity men was higher than that in normal BMI and low BMI group (P<0.05), overweight group was higher than normal BMI group (P<0.05); blood pressure failure rate in obesity women was higher than that in normal BMI and low BMI group (P<0.05). There was a statistically significant difference in blood pressure control rate of different age groups (60-70, 71-80, >80 years old) among low BMI group, normal BMI group, overweight and obesity group (chi2=37.729, 20.007, 15.538, respectively, P<0.001). Blood pressure failure rate in obesity patients with 60-70 years old was higher than that in overweight and normal BMI group (P<0.05), blood pressure failure rates in obesity and overweight patients with 71-80 and > 80 years old were also higher than those in normal BMI group (P<0.05). Multivariable Logistic regression equation showed that overweight in overall population (OR=1.313, 95%CI 1.170-1.731, P<0.05), obesity (OR=2.295, 95%CI 2.295-1.496, P<0.05) were independent risk factors for blood pressure failure rate, in addition, obesity was also risk factor for blood pressure failure rate in men and women patients. Conclusions: Increased BMI has an adverse effect on blood pressure control rate in elderly CHD outpatients with hypertension, and may be the independent risk for blood pressure failure rate in those patients. Much more attention should be given to control BMI level so as to increase the blood pressure success rate and improve the patients' prognosis. PMID- 27686553 TI - MYC amplification in angiosarcomas arising in the setting of chronic lymphedema of morbid obesity. AB - BACKGROUND: Angiosarcoma is a malignancy of vascular endothelial cells which may arise secondarily as a complication of lymphedema, including chronic lymphedema of morbid obesity. Amplifications in MYC are frequently present in secondary angiosarcoma (arising in irradiated sites and chronic lymphedema) and less frequently in primary cutaneous angiosarcoma. OBJECTIVE: To describe the presence of MYC amplifications in two cases of cutaneous angiosarcoma secondary to chronic lymphedema of morbid obesity. METHODS: This study is a case series of two patients with cutaneous angiosarcoma. Clinical data was retrieved from the medical records. Histopathological analysis of the biopsy specimens was performed, including immunohistochemistry, along with fluorescence in situ hybridization. RESULTS: Angiosarcoma arose in the setting of massive chronic lymphedema complicating morbid obesity without other predisposing risk factors. Both cases exhibited epithelioid cell morphology and high-level MYC amplification. CONCLUSION: We report MYC amplification in two cases of angiosarcoma arising in massive chronic lymphedema of morbid obesity. PMID- 27686554 TI - The value of time-to-onset in statistical signal detection of adverse drug reactions: a comparison with disproportionality analysis in spontaneous reports from the Netherlands. AB - PURPOSE: In pharmacovigilance, the commonly used disproportionality analysis (DPA) in statistical signal detection is known to have its limitations. The aim of this study was to investigate the value of the time to onset (TTO) of ADRs in addition to DPA. METHODS: We performed a pilot study using individual case safety reports (ICSRs) for three drugs (Cervarix(r), nitrofurantoin and simvastatin) from the Lareb spontaneous reporting database. TTO distributions for drug - ADR associations were compared to other ADRs for the same drug and to other drugs for the same ADR using two-sample Anderson-Darling testing. Statistically significant associations were considered true positive (TP) signals if the association was present in the official product information of the drug. Sensitivity and specificity for the TTO method were compared with the DPA method. As a measure of disproportionality, the reporting odds ratio (ROR) was used. RESULTS: In general, sensitivity was lower, and specificity was higher for the TTO method compared to DPA. The TTO method showed similar sensitivity for all three drugs, whereas specificity was lower for Cervarix(r). Eight additional TP signals were found using the TTO method compared to DPA. CONCLUSIONS: Our study shows that statistical signal detection based on the TTO alone resulted in a limited number of additional signals compared to DPA. We therefore conclude that the TTO method is of limited value for full database statistical screening in our setting. Copyright (c) 2016 John Wiley & Sons, Ltd.

PMID- 27686556 TI - A meta-analysis for echocardiographic assessment of right ventricular structure and function in ARVC. AB - INTRODUCTION: Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is an inherited pathology that can increase the risk of sudden death. Current Task Force Criteria for echocardiographic diagnosis do not include new, regional assessment tools which may be relevant in a phenotypically diverse disease. We adopted a systematic review and meta-analysis approach to highlight echocardiographic indices that differentiated ARVC patients and healthy controls. METHODS: Data was extracted and analysed from prospective trials that employed a case-control design meeting strict inclusion and exclusion as well as a-priori quality criteria. Structural indices included proximal RV outflow tract(RVOT1) and RV diastolic area(RVDarea). Functional indices included RV fractional area change (RVFAC), Tricuspid Annular Systolic Excursion(TAPSE), peak systolic and early diastolic myocardial velocities (S' and E' respectively) and myocardial strain. RESULTS: Patients with ARVC had larger RVOT1 (mean ? SD; 34 vs. 28 mm P<0.001) and RVDarea (23 vs. 18 cm2 P<0.001) compared to healthy controls. ARVC patients also had lower RVFAC (38 vs. 46 % P<0.001), TAPSE(17 vs. 23 mm P<0.001), S' (9 vs. 12 cm.s-1 P<0.001), E' (9 vs. 13 cm.s-1 P<0.001) and myocardial strain (-17 vs. -30% P<0.001). CONCLUSION: The data from this meta-analysis support current Task Force criteria for the diagnosis of ARVC. In addition, other RV measures that reflect the complex geometry and function in ARVC clearly differentiated between ARVC and healthy controls and may provide additional diagnostic and management value. We recommend that future working groups consider this data when proposing new / revised criteria for the echocardiographic diagnosis of ARVC.

AB - We report a 16-year-old male patient diagnosed with paratesticular rhabdomyosarcoma and mediastinal tuberculous lymphadenitis. The differential diagnosis between high or early stage of rhabdomyosarcoma and tuberculosis (TB) was critical in this patient without a history of TB. Unexpected lymphadenopathies detected during the staging of patients with malignancy should be carefully evaluated, and TB should be taken into consideration in the differential diagnosis especially in underdeveloped and developing countries. Unnecessary additional treatments increase the rate of mortality and morbidity because of upstaging of cancer. Further, TB reactivation can be seen during chemotherapy because of immunosuppression. PMID- 27686558 TI - Prediction of Bronchial Mucus Plugs Formation in Patients with Refractory Mycoplasma Pneumoniae Pneumonia. AB - Background: We aimed to find the relationship between the clinical characteristics and mucus plug formation and developed models to predict mucus plug formation in refractory Mycoplasma pneumoniae pneumonia (RMPP) infection. Methods: RMPP patients treated with bronchoscopy were retrospectively enrolled in the study between November 2011 and November 2015. Multivariate logistic regression was performed to identify independent predictors of mucus plug formation. Results: Of the 173 RMPP patients enrolled, the mucus plug group accounted for 82 (47.4%) cases. Multivariate logistic regression analysis identified age, fever duration, C-reactive protein (CRP) and lactic dehydrogenase (LDH) as independent risk factors for mucus plug. We assigned one point for age, length of fever and CRP and two points for LDH. Using this predicted score, we identified patients with mucus plug with 71.8% sensitivity and 78.9% specificity. Conclusions: Our predictive models based on demographic and laboratory variables accurately predicted mucus plug formation in initial treatment of patients with RMPP.

AB - A molecular dynamics method was employed to study the binding energies associated with the cocrystallization (at selected crystal planes) of either 1,3,5-triamino 2,4,6-trinitro-benzene (TATB), 1,1-diamino-2,2-dinitroethylene, 3-nitro-1,2,4 triazol-5-one (TATB, FOX-7, and NTO, respectively, all of which are explosives), or N,N-dimethylformamide (DMF, a nonenergetic solvent) in various molar ratios with 1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane in its alpha and beta conformations (alpha-HMX and beta-HMX, respectively). The results showed that the cocrystals with low molar ratios (2:1, 1:1, 1:2, and 1:3) were the most stable. The binding energies of HMX/NTO and HMX/DMF were larger than those of HMX/TATB and HMX/FOX-7. According to the calculated stabilities, HMX prefers to adopt its alpha form in HMX/TATB and its beta form in HMX/NTO, whereas the two forms coexist in HMX/FOX-7. For HMX/TATB, HMX/NTO, and alpha-HMX/FOX-7, increasing the proportion of the cocrystal component with the highest detonation heat (HMX in the first two cases, FOX-7 in the latter) increases the detonation heat, velocity, and pressure of the cocrystal. However, increasing the proportion of the component with the highest detonation heat in beta-HMX/FOX-7 and gamma-CL 20/FOX-7 increases the detonation heat of the cocrystal but decreases its detonation velocity. An investigation of the surface electrostatic potential revealed how the sensitivity changes upon cocrystal formation. Graphical Abstract Surface electrostatic potential of HMX/TATB. PMID- 27686559 TI - Evaluating genomic DNA extraction methods from human whole blood using endpoint and real-time PCR assays. AB - The extraction of genomic DNA is the crucial first step in large-scale epidemiological studies. Though there are many popular DNA isolation methods from human whole blood, only a few reports have compared their efficiencies using both end-point and real-time PCR assays. Genomic DNA was extracted from coronary artery disease patients using solution-based conventional protocols such as the phenol-chloroform/proteinase-K method and a non-phenolic non-enzymatic Rapid Method, which were evaluated and compared vis-a-vis a commercially available silica column-based Blood DNA isolation kit. The appropriate method for efficiently extracting relatively pure DNA was assessed based on the total DNA yield, concentration, purity ratios (A260/A280 and A260/A230), spectral profile and agarose gel electrophoresis analysis. The quality of the isolated DNA was further analysed for PCR inhibition using a murine specific ATP1A3 qPCR assay and mtDNA/Y-chromosome ratio determination assay. The suitability of the extracted DNA for downstream applications such as end-point SNP genotyping, was tested using PCR-RFLP analysis of the AGTR1-1166A>C variant, a mirSNP having pharmacogenetic relevance in cardiovascular diseases. Compared to the traditional phenol-chloroform/proteinase-K method, our results indicated the Rapid-Method to be a more suitable protocol for genomic DNA extraction from human whole blood in terms of DNA quantity, quality, safety, processing time and cost. The Rapid Method, which is based on a simple salting-out procedure, is not only safe and cost-effective, but also has the added advantage of being scaled up to process variable sample volumes, thus enabling it to be applied in large-scale epidemiological studies. PMID- 27686561 TI - Benchmarking the DFT methodology for assessing antioxidant-related properties: quercetin and edaravone as case studies. AB - The overall objective was to identify an accurate computational electronic method to virtually screen phenolic compounds through their antioxidant and free-radical scavenging activity. The impact of a key parameter of the density functional theory (DFT) approach was studied. Performances of the 21 most commonly used exchange-correlation functionals are thus detailed in the evaluation of the main energetic parameters related to the activities of two prototype antioxidants, namely quercetin and edaravone, is reported. These functionals have been chosen among those belonging to three different families of hybrid functionals, namely global, range separated, and double hybrids. Other computational parameters have also been considered, such as basis set and solvent effects. The selected parameters, namely bond dissociation enthalpy (BDE), ionization potential (IP), and proton dissociation enthalpy (PDE) allow a mechanistic evaluation of the antioxidant activities of free radical scavengers. Our results show that all the selected functionals provide a coherent picture of these properties, predicting the same order of BDEs and PDEs. However, with respect to the reference values, the errors found at CBS-Q3 level significantly vary with the functional. Although it is difficult to evidence a global trend from the reported data, it clearly appears that LC-omegaPBE, M05-2X, and M06-2X are the most suitable approaches for the considered properties, giving the lowest cumulative mean absolute errors. These methods are therefore suggested for an accurate and fast evaluation of energetic parameters related to an antioxidant activity via free radical scavenging. PMID- 27686562 TI - Protonation and electronic structure of 2,6-dichlorophenolindophenolate during reduction. A theoretical study including explicit solvent. AB - Protonation in the two-electron/two-proton reduction processes of 2,6 dichlorophenolindophenolate (DCIP) is investigated combining density functional theory (DFT) and molecular dynamics (MD) methods. DCIP (anion), DCIP*- (radical anion), and DCIP2- (dianion) are considered, including the electronic structure analysis from the prospective of quantum theory of atoms and molecules (QTAIM). It is shown that oxygen on the indophenolate moiety and nitrogen are the first and/or the second proton acceptor sites and their energetic order depends on the total charge of the system. MD simulations of differently charged species interacting with the solvent molecules have been performed for methanol, water, and oxonium cation (H3O+). Methanol and water molecules are found to form only hydrogen bonds with the solute irrespective of its charge. The calculated pKa values show that the imino group of DCIPH- is a weaker acid than water. While in the case of DCIP (and DCIP*-) plus oxonium cation, proton transfer from the solvent to the solute was evidenced for both aforementioned acceptor sites. In addition, MD simulations of bulks containing 15 and 43 molecules of water around the DCIP molecule have been performed, revealing the formation of 2-4 hydrogen bonds. Graphical Abstract 2,6-Dichlorophenolindophenolate interacts with solvent molecules (water, oxonium cation and methanol). Hydrogen transfer and electronic structure are studied by DFT and molecular dynamics methods. PMID- 27686565 TI - Evolving Surgical Interventions in the Treatment of Glaucoma. AB - Interventions in the treatment of mild to moderate glaucoma have evolved to include a group of procedures collectively named "Minimally Invasive Glaucoma Surgery (MIGS)." These procedures are less invasive than traditional filtering surgery and setons and offer the benefit of an improved side-effect profile. A review of current published literature has shown that these procedures offer lower intraocular pressure, decrease reliance on topical medications, have no negative effect on refractive outcomes, and can be safely done following failed tube surgery. PMID- 27686563 TI - Neuroinflammatory component of gray matter pathology in multiple sclerosis. AB - OBJECTIVE: In multiple sclerosis (MS), using simultaneous magnetic resonance positron emission tomography (MR-PET) imaging with 11 C-PBR28, we quantified expression of the 18kDa translocator protein (TSPO), a marker of activated microglia/macrophages, in cortex, cortical lesions, deep gray matter (GM), white matter (WM) lesions, and normal-appearing WM (NAWM) to investigate the in vivo pathological and clinical relevance of neuroinflammation. METHODS: Fifteen secondary-progressive MS (SPMS) patients, 12 relapsing-remitting MS (RRMS) patients, and 14 matched healthy controls underwent 11 C-PBR28 MR-PET. MS subjects underwent 7T T2*-weighted imaging for cortical lesion segmentation, and neurological and cognitive evaluation. 11 C-PBR28 binding was measured using normalized 60- to 90-minute standardized uptake values and volume of distribution ratios. RESULTS: Relative to controls, MS subjects exhibited abnormally high 11 C PBR28 binding across the brain, the greatest increases being in cortex and cortical lesions, thalamus, hippocampus, and NAWM. MS WM lesions showed relatively modest TSPO increases. With the exception of cortical lesions, where TSPO expression was similar, 11 C-PBR28 uptake across the brain was greater in SPMS than in RRMS. In MS, increased 11 C-PBR28 binding in cortex, deep GM, and NAWM correlated with neurological disability and impaired cognitive performance; cortical thinning correlated with increased thalamic TSPO levels. INTERPRETATION: In MS, neuroinflammation is present in the cortex, cortical lesions, deep GM, and NAWM, is closely linked to poor clinical outcome, and is at least partly linked to neurodegeneration. Distinct inflammatory-mediated factors may underlie accumulation of cortical and WM lesions. Quantification of TSPO levels in MS could prove to be a sensitive tool for evaluating in vivo the inflammatory component of GM pathology, particularly in cortical lesions. Ann Neurol 2016;80:776-790. PMID- 27686564 TI - Theorizing epigenesis in a time of preexistence: From the end of the seventeenth century to the 1720s. AB - According to a classic periodization in the history of science, biological thought as it emerged in France from the last decades of the seventeenth century to the 1740s was strongly committed to the doctrine of the preexistence of germs. Nicolas Malebranche's role in disseminating this paradigm, particularly in the milieu of the Academie Royale des Sciences during the years when Bernard Le Bouyer de Fontenelle was its secretary, has been studied in detail, especially by Jacques Roger. However, much less has been said about the authors who argued against this doctrine prior to the appearance of the relevant pieces by Pierre Louis Moreau de Maupertuis, Georges-Louis Leclerc, Comte de Buffon, and Denis Diderot. I aim to examine a series of French medical treatises and clandestine manuscripts that outlined a mechanist theory of epigenesis, between the end of the seventeenth century and the 1720s, to bring to light the strategies-often quite original-that allowed them to achieve this result. One interesting case is the heterodox readers of Malebranche, which use some of his own arguments (notably on the physiology of brain traces and the laws of nature) both against preexistence and to support epigenesis. I inquire into the historical worth of the positions defended by these authors as well as into the connections existing between the history of epigenesis and that of materialism in the early modern era.

AB - OBJECTIVES: To investigate the relationship between image quality and patient size at 100 kilovoltage (kV) compared to 120 kV ECG-gated Triple-Rule-Out CT angiography (TRO-CTA). METHODS: We retrospectively included 73 patients (age 64 +/- 14 years) who underwent retrospective ECG-gated chest CTA. 40 patients were scanned with 100 kV while 33 patients with 120 kV. Body mass index (BMI), patients' chest circumference (PC) and thoracic surface area (TSA) were recorded. Quantitative image quality was assessed as vascular attenuation in the ascending aorta (AA), pulmonary trunk (PA) and left coronary artery (LCA) and the signal-to noise ratio (SNR) in the AA. RESULTS: There was no significant difference in BMI (26.0 +/- 4.6 vs. 28.0 +/- 6.7 kg/m2), PC (103 +/- 7 vs. 104 +/- 10 cm2) and TSA (92 +/- 15 vs. 91 +/- 19 cm2) between 100 kV and 120 kV group. Mean vascular attenuation was significantly higher in the 100 kV compared to the 120 kV group (AA 438 vs. 354 HU, PA 460 vs. 349 HU, LCA 370 vs. 299 HU all p < 0.001). SNR was not significantly different, even after adjusting for patient size. Radiation dose was significantly lower in the 100 kV group (10.7 +/- 4.1 vs. 20.7 +/- 10.7 mSv; p < 0.001). CONCLUSIONS: 100 kV TRO-CTA is feasible in normal-to-overweight patients while maintaining image quality and achieving substantial dose reduction. KEY POINTS: * 100 kV protocols result in a significantly lower radiation dose. * Mean vascular attenuation is significantly higher using 100 kV. * SNR and CNR are not significantly different between 100 kV and 120 kV. * 100 kV CTA is feasible regardless of patient size while maintaining image quality. PMID- 27686567 TI - Anaplastic lymphoma kinase positive large B-cell lymphoma: Literature review and report of an endoscopic fine needle aspiration case with tigroid backgrounds mimicking seminoma. AB - Anaplastic lymphoma kinase-positive large B-cell lymphoma (ALK+ LBCL) is a rare distinct type of non-Hodgkin's lymphoma that arises in association with alterations of the ALK gene. This distinct disease entity is typically associated with an aggressive clinical course and appears in light microscopic preparations as a monomorphic population of large, immunoblast-like cells. In this report, we describe a case of ALK+ LBCL diagnosed by transgastric endoscopic ultrasound guided fine needle aspiration (EUS FNA) of splenic hilar lymph nodes. Modified Giemsa stained direct smears from the FNA sample demonstrated large lesional cells with foamy cytoplasm and macronucleoli admixed with small lymphocytes in tigroid backgrounds, mimicking the cytologic appearance of seminoma. Ancillary immunohistochemical studies subsequently confirmed the diagnosis of ALK+ LBCL with the lesional cells being immunoreactive for CD138, VS38c, MUM1, ALK1, and lambda light chain. The cohesiveness of the cells, the cellular morphology, and the tigroid backgrounds were all pitfalls for accurate diagnosis of this rare specific type of lymphoid malignancy by cytology. To our knowledge this is the first case report detailing the diagnosis of ALK+ LBCL by EUS FNA and the first report describing a glycogen-rich tigroid background in direct FNA smears. Establishing a refined diagnosis in cases of this rare form of LBCL is necessary, as therapies targeting ALK may be of value in clinical management. Diagn. Cytopathol. 2017;45:148-155.

AB - INTRODUCTION AND HYPOTHESIS: The objective was to investigate the expression of endothelial nitric oxide synthase (eNOS) and phosphodiesterase (PDE) 5 in vaginal tissue of premenopausal women experiencing stress urinary incontinence (SUI) with and without sexual dysfunction. METHODS: Women presenting for treatment of SUI were screened using the Female Sexual Function Index (FSFI) and 10 were selected who met the criteria for female sexual dysfunction (FSD) and 10 asymptomatic controls. Vaginal tissue specimens were obtained from those premenopausal women aged >=40 years who had had sexual activity >=2 times every month for the last 6 months and who were scheduled to undergo surgery for SUI. FSD criteria was FSFI scores <18 and arousal domain scores <3. The control group had FSFI scores >=26 and individual domain scores >=4. The expressions of eNOS and PDE 5 were compared in the two groups using immunofluorescence staining and western blotting. RESULTS: The mean total FSFI scores were 30.4 +/- 2.6 and 15.3 +/- 2.3 in the control and FSD groups respectively. In immunofluorescence staining, eNOS and PDE5 were localized in the vaginal epithelium. In western blotting, the expressions of eNOS and PDE5 were significantly lower in the FSD group than in the control group (p = 0.003 and p = 0.038 respectively). CONCLUSIONS: eNOS and PDE5 in the vagina may play important roles in the pathophysiology of FSD. PMID- 27686569 TI - Five years after midurethral sling surgery for stress incontinence: obesity continues to have an impact on outcomes. AB - INTRODUCTION AND HYPOTHESIS: The objective was to evaluate the impact of preoperative body mass index >=30 on objective and subjective cure rates 5 years after midurethral sling surgery. METHODS: Secondary analysis of the 5-year results of a randomized clinical trial evaluating tension-free vaginal tape vs transobturator tape surgery. Women (n = 176) were classified as obese or non obese based on preoperative height and weight. Women self-reported symptoms and quality of life, and underwent standardized physical examinations and pad testing. Categorical data were analyzed using Chi-squared or Fisher's exact tests, continuous data by Mann-Whitney U test. Primary outcome was objective cure defined as <1 g urine lost on pad-test at 5 years post-surgery. Secondary outcomes were subjective cure of incontinence, urinary urge incontinence symptoms, and quality of life scores. RESULTS: Non-obese women had a higher rate of objective cure, 87.4 % (n = 83 out of 95) compared with 65.9 % (n = 29 out of 44) in the obese group (P = 0.003, risk difference [RD] 21.5 %, 95 % CI 5.9-37.0 %). Subjectively, non-obese women also reported higher rates of cure, 76.7 % (n = 89 out of 116) compared with 53.6 % (n = 30 out of 56) of obese women (P = 0.002, RD 23.2 %, 95 % CI 8.0-38.3 %). Overall rates of urge incontinence symptoms were similar in the two groups, but rates of bothersome symptoms were higher for obese women (58.9 % vs 42.1 %, P = 0.039, RD 16.8 % 95 % CI 1.1-32.6). CONCLUSIONS: Five years after surgery, obese women continued to experience lower rates of cure compared with non-obese women. PMID- 27686571 TI - Physical exercise induces structural alterations in the hippocampal astrocytes: exploring the role of BDNF-TrkB signaling. AB - While it has been known that physical activity can improve cognitive function and protect against neurodegeneration, the underlying mechanisms for these protective effects are yet to be fully elucidated. There is a large body of evidence indicating that physical exercise improves neurogenesis and maintenance of neurons. Yet, its possible effects on glial cells remain poorly understood. Here, we tested whether physical exercise in mice alters the expression of trophic factor-related genes and the status of astrocytes in the dentate gyrus of the hippocampus. In addition to a significant increase in Bdnf mRNA and protein levels, we found that 4 weeks of treadmill and running wheel exercise in mice, led to (1) a significant increase in synaptic load in the dentate gyrus, (2) alterations in astrocytic morphology, and (3) orientation of astrocytic projections towards dentate granule cells. Importantly, these changes were possibly linked to increased TrkB receptor levels in astrocytes. Our study suggests that astrocytes actively respond and could indeed mediate the positive effects of physical exercise on the central nervous system and potentially counter degenerative processes during aging and neurodegenerative disorders. PMID- 27686570 TI - A thicker intima-media carotid wall was found in a cohort of children with recent onset migraine. AB - AIM: Migraine affects approximately 10-20% of the general population, including children and adolescents, and an association between migraine and increased risks for cardiovascular disease and stroke have been reported in adult patients. This study aimed to address the lack of data on children with migraine. METHODS: This study comprised 30 children and adolescents (16 male) with migraine. We evaluated their biochemical profile, glucose homeostasis, vascular function by flow mediated dilatation and arterial structure by carotid intima-media thickness (cIMT). A group of 32 age, sex and auxologically matched children (17 male) served as controls. RESULTS: The group of children with migraine had a normal biochemical profile and glucose homeostasis, but presented with significantly thicker cIMT than the control group (0.48 +/- 0.07 mm versus 0.45 +/- 0.04, p < 0.05). CONCLUSION: We observed a significantly thicker cIMT in children with migraine compared with the controls. The brief time interval between the onset of the disease and the time of the study makes it unlikely that repetitive migraine attacks could be responsible for the thickening of the cIMT. Thus, it may be speculated that primitive vascular function abnormalities were wholly or partly responsible for the development of migraine in this paediatric cohort. PMID- 27686572 TI - Fractures of the axis: a review of pediatric, adult, and geriatric injuries. AB - Fractures of the second cervical vertebra (C2, axis) are common in adult spine surgery. Those fractures occurring in younger adult patients are often associated with high-energy mechanism trauma, resulting in a "Hangman's Fracture." Management of these fractures is often successful with nonoperative means, though surgery may be needed in those fractures with greater displacement and injury to the C2-C3 disc. Older patients are more likely to sustain fractures of the odontoid process. The evidence supporting surgical management of these fractures is evolving, as there may be a mortality benefit to surgery. Regardless of treatment, longer-term mortality rates are high in this patient population, which should be discussed with the patient and family at the time of injury. Pediatric patients may suffer fractures of the axis, though differentiation of normal and pathologic findings is necessary and more difficult with the skeletally immature spine. PMID- 27686573 TI - Knowledge is power: Issues of measuring training and performance in cycling. AB - Mobile power meters provide a valid means of measuring cyclists' power output in the field. These field measurements can be performed with very good accuracy and reliability making the power meter a useful tool for monitoring and evaluating training and race demands. This review presents power meter data from a Grand Tour cyclist's training and racing and explores the inherent complications created by its stochastic nature. Simple summary methods cannot reflect a session's variable distribution of power output or indicate its likely metabolic stress. Binning power output data, into training zones for example, provides information on the detail but not the length of efforts within a session. An alternative approach is to track changes in cyclists' modelled training and racing performances. Both critical power and record power profiles have been used for monitoring training-induced changes in this manner. Due to the inadequacy of current methods, the review highlights the need for new methods to be established which quantify the effects of training loads and models their implications for performance. PMID- 27686574 TI - Coronary Physiology Assessment for the Diagnosis and Treatment of Stable Ischemic Heart Disease. AB - Coronary artery disease is the most prevalent cardiovascular disease in the USA. In the majority of settings, percutaneous coronary intervention (PCI) for stable coronary artery disease (CAD) reduces angina and improves quality of life; however, it does not improve survival and is associated with infrequent but serious complications. Selection of appropriate patients and coronary lesions for revascularization with PCI is crucial to maximize the benefit-to-risk ratio. The assessment of the hemodynamic significance of intermediate coronary lesions has been shown to improve outcomes and reduce healthcare costs. The current review summarizes the existing evidence regarding the physiological assessment of coronary lesions, with emphasis on fractional flow reserve, the most common invasive hemodynamic assessment modality. PMID- 27686575 TI - Knowledge and attitude of parents/caregivers towards hearing loss and screening in newborns - a systematic review. AB - OBJECTIVE: The parents/caregivers of a newborn play a pivotal role in the process of hearing screening and intervention. The decisions taken by them depend on their knowledge and attitude. The purpose of this study was to review the literature systematically on knowledge and attitude of parents/caregivers towards infant hearing loss and newborn hearing screening. DESIGN: A systematic search was conducted using electronic databases for the periods from 1990 to March 2016. Two authors scrutinized the studies and extracted the data based on predetermined criteria. STUDY SAMPLE: Ten studies. RESULTS: Ear discharge was correctly identified as a risk factor for hearing loss along with measles, drugs/medication, family history, congenital causes and noise exposure. The studies revealed mixed results for knowledge about newborn hearing screening. Overall, the parents/caregivers showed positive attitudes towards hearing screening and intervention options. However, due to heterogeneity in the studies, it's hard to derive a conclusion. CONCLUSIONS: The present review sheds light on the common areas of misconception among parents/caregivers about risk factors of infant hearing loss and newborn hearing screening. The review also draws attention to the need to have more studies exploring this knowledge and attitude of parents/caregivers among diverse populations. PMID- 27686576 TI - Modulation of inflammation and disease tolerance by DNA damage response pathways. AB - The accurate replication and repair of DNA is central to organismal survival. This process is challenged by the many factors that can change genetic information such as replication errors and direct damage to the DNA molecule by chemical and physical agents. DNA damage can also result from microorganism invasion as an integral step of their life cycle or as collateral damage from host defense mechanisms against pathogens. Here we review the complex crosstalk of DNA damage response and immune response pathways that might be evolutionarily connected and argue that DNA damage response pathways can be explored therapeutically to induce disease tolerance through the activation of tissue damage control processes. Such approach may constitute the missing pillar in the treatment of critical illnesses caused by multiple organ failure, such as sepsis and septic shock. PMID- 27686577 TI - Biparental chloroplast inheritance leads to rescue from cytonuclear incompatibility. AB - Although organelle inheritance is predominantly maternal across animals and plants, biparental chloroplast inheritance has arisen multiple times in the angiosperms. Biparental inheritance has the potential to impact the evolutionary dynamics of cytonuclear incompatibility, interactions between nuclear and organelle genomes that are proposed to be among the earliest types of genetic incompatibility to arise in speciation. We examine the interplay between biparental inheritance and cytonuclear incompatibility in Campanulastrum americanum, a plant species exhibiting both traits. We first determine patterns of chloroplast inheritance in genetically similar and divergent crosses, and then associate inheritance with hybrid survival across multiple generations. There is substantial biparental inheritance in C. americanum. The frequency of biparental inheritance is greater in divergent crosses and in the presence of cytonuclear incompatibility. Biparental inheritance helps to mitigate cytonuclear incompatibility, leading to increased fitness of F1 hybrids and recovery in the F2 generation. This study demonstrates the potential for biparental chloroplast inheritance to rescue cytonuclear compatibility, reducing cytonuclear incompatibility's contribution to reproductive isolation and potentially slowing speciation. The efficacy of rescue depended upon the strength of incompatibility, with a greater persistence of weak incompatibilities in later generations. These findings suggest that incompatible plastids may lead to selection for biparental inheritance. PMID- 27686578 TI - Domestic work division and satisfaction in cohabiting adults: Associations with life satisfaction and self-rated health. AB - BACKGROUND: The amount and perception of domestic work may affect satisfaction with everyday life, but further knowledge is needed about the relationship between domestic work division and health and well-being. AIM: To describe the division of, and satisfaction with, domestic work and responsibility for home/family in adults living with a partner. A further aim was to investigate the associations between these aspects and self-rated life satisfaction and health. METHOD: Data from the Work, Lipids and Fibrinogen survey collected 2009 were used, comprising 4924 participants living with a partner. Data were analyzed using logistic regression. RESULTS: The majority shared domestic work and responsibility for home/family equally with their partner. However, more women conducted the majority of the domestic work and were less satisfied with its division. When both division and satisfaction with division was included in the analysis, solely satisfaction with the division and the responsibility were associated with higher odds for good life satisfaction. Regarding health, higher odds for good self-rated health were seen in those who were satisfied with their division of responsibility. CONCLUSION AND SIGNIFICANCE: The results highlight the importance of taking into account not solely the actual division of domestic work but also the satisfaction with it. PMID- 27686579 TI - A case report of a deep surgical site infection with Terrisporobacter glycolicus/T. Mayombei and review of the literature. AB - BACKGROUND: There are increasing data regarding Terrisporobacter glycolicus as an emerging anaerobic pathogen. However, the few published cases to date usually report it as part of a polymicrobial infection. Here, we describe the first reported monomicrobial surgical site infection with this bacterium. Identification methods, taxonomy, and clinical management of this rarely identified pathogen are also discussed. CASE PRESENTATION: A previously healthy 66-year-old sustained an open olecranon fracture of his left arm after trauma. He subsequently underwent open reduction and internal fixation (ORIF), with insertion of an olecranon locking plate and two locking screws. Ten days after surgery, the patient developed increasing pain at the surgical site and noted green discharge from the wound. Culture of the wound discharge yielded grew a pure Gram-positive anaerobe identified by the RapidANA(r) microbial identification system as C. difficile (profile 000010, 99.1 % probability). Reference laboratory testing identified the isolate as T. glycolicus/mayombei (previously designated as Clostridium glycolicum/mayombei) by 16S rRNA gene sequencing and as Clostridium glycolicum by MALDI-TOF mass spectrometry. The patient received an 8-week course of moxifloxacin and metronidazole with an excellent clinical response at 12 months' follow-up. CONCLUSIONS: We describe the case of a deep surgical site infection with T. glycolicus/mayombei (formerly known as Clostridium glycolicum and Clostridium mayombei, respectively), which extends our knowledge of the clinical spectrum of this pathogen. The isolate was misidentified by phenotypic identification methods. PMID- 27686580 TI - Modelling drug flux through microporated skin. AB - A simple mathematical equation has been developed to predict drug flux through microporated skin. The theoretical model is based on an approach applied previously to water evaporation through leaf stomata. Pore density, pore radius and drug molecular weight are key model parameters. The predictions of the model were compared with results derived from a simple, intuitive method using porated area alone to estimate the flux enhancement. It is shown that the new approach predicts significantly higher fluxes than the intuitive analysis, with transport being proportional to the total pore perimeter rather than area as intuitively anticipated. Predicted fluxes were in good general agreement with experimental data on drug delivery from the literature, and were quantitatively closer to the measured values than those derived from the intuitive, area-based approach. PMID- 27686581 TI - Temperature responsive porous silicon nanoparticles for cancer therapy - spatiotemporal triggering through infrared and radiofrequency electromagnetic heating. AB - : One critical functionality of the carrier system utilized in targeted drug delivery is its ability to trigger the release of the therapeutic cargo once the carrier has reached its target. External triggering is an alluring approach as it can be applied in a precise spatiotemporal manner. In the present study, we achieved external triggering through the porous silicon (PSi) nanoparticles (NPs) by providing a pulse of infrared or radiofrequency radiation. The NPs were grafted with a temperature responsive polymer whose critical temperature was tailored to be slightly above 37 degrees C. The polymer coating improved the biocompatibility of the NPs significantly in comparison with their uncoated counterparts. Radiation induced a rapid temperature rise, which resulted in the collapse of the polymer chains facilitating the cargo release. Both infrared and radiofrequency radiation were able to efficiently trigger the release of the encapsulated drug in vitro and induce significant cell death in comparison to the control groups. Radiofrequency radiation was found to be more efficient in vitro, and the treatment efficacy was verified in vivo in a lung carcinoma (3LL) mice model. After a single intratumoral administration of the carrier system combined with radiofrequency radiation, there was clear suppression of the growth of the carcinoma and a prolongation of the survival time of the animals. TOC IMAGE: The temperature responsive (TR) polymer grafted on the surface of porous silicon nanoparticles (PSi NPs) changes its conformation in response to the heating induced by infrared or radiofrequency radiation. The conformation change allows the loaded doxorubicin to escape from the pores, achieving controlled drug release from TR PSi NPs, which displayed efficacy against malignant cells both in vitro and in vivo. PMID- 27686582 TI - Intracellular delivery and ultrasonic activation of folate receptor-targeted phase-change contrast agents in breast cancer cells in vitro. AB - Breast cancer is a diverse and complex disease that remains one of the leading causes of death among women. Novel, outside-of-the-box imaging and treatment methods are needed to supplement currently available technologies. In this study, we present evidence for the intracellular delivery and ultrasound-stimulated activation of folate receptor (FR)-targeted phase-change contrast agents (PCCAs) in MDA-MB-231 and MCF-7 breast cancer cells in vitro. PCCAs are lipid-coated, perfluorocarbon-filled particles formulated as nanoscale liquid droplets capable of vaporization into gaseous microbubbles for imaging or therapy. Cells were incubated with 1:1 decafluorobutane (DFB)/octafluoropropane (OFP) PCCAs for 1h, imaged via confocal microscopy, exposed to ultrasound (9MHz, MI=1.0 or 1.5), and imaged again after insonation. FR-targeted PCCAs were observed intracellularly in both cell lines, but uptake was significantly greater (p<0.001) in MDA-MB-231 cells (93.0% internalization at MI=1.0, 79.5% at MI=1.5) than MCF-7 cells (42.4% internalization at MI=1.0, 35.7% at MI=1.5). Folate incorporation increased the frequency of intracellular PCCA detection 45-fold for MDA-MB-231 cells and 7-fold for MCF-7 cells, relative to untargeted PCCAs. Intracellularly activated PCCAs ranged from 500nm to 6MUm (IQR=800nm-1.5MUm) with a mean diameter of 1.15+/-0.59 (SD) microns. The work presented herein demonstrates the feasibility of PCCA intracellular delivery and activation using breast cancer cells, illuminating a new platform toward intracellular imaging or therapeutic delivery with ultrasound. PMID- 27686583 TI - High intensity focused ultrasound hyperthermia for enhanced macromolecular delivery. AB - Mild hyperthermia has been used in combination with polymer therapeutics to further increase delivery to solid tumors and enhance efficacy. An attractive method for generating heat is through non-invasive high intensity focused ultrasound (HIFU). HIFU is often used for ablative therapies and must be adapted to produce uniform mild hyperthermia in a solid tumor. In this work a magnetic resonance imaging guided HIFU (MRgHIFU) controlled feedback system was developed to produce a spatially uniform 43 degrees C heating pattern in a subcutaneous mouse tumor. MRgHIFU was employed to create hyperthermic conditions that enhance macromolecular delivery. Using a mouse model with two subcutaneous tumors, it was demonstrated that MRgHIFU enhanced delivery of both Evans blue dye (EBD) and Gadolinium-chelated N-(2-hydroxypropyl)methacrylamide (HPMA) copolymers. The EBD accumulation in the heated tumors increased by nearly 2-fold compared to unheated tumors. The Gadolinium-chelated HPMA copolymers also showed significant enhancement in accumulation over control as evaluated through MRI T1-mapping measurements. Results show the potential of HIFU-mediated hyperthermia for enhanced delivery of polymer therapeutics. PMID- 27686584 TI - Necrobiosis Lipoidica. PMID- 27686585 TI - Congenital Anorectal Malformation Severity Does Not Predict Severity of Congenital Heart Defects. AB - OBJECTIVE: To determine the prevalence of congenital heart defects (CHDs) in patients with mild or severe congenital anorectal malformations (CARMs), and whether all patients with CARM need pediatric cardiology screening. STUDY DESIGN: We included 129 patients with CARM born between 2004 and 2013, and referred to University Medical Center Groningen. Recto-perineal and recto-vestibular fistulas were classified as mild CARMs, all others as severe. Significant patent foramen ovale, secundum atrial septal defect, and small ventricular septum defect were classified as minor CHDs, all others as major. RESULTS: Of 129 patients with CARM, 67% had mild CARM, 33% severe CARM, and 17% were additionally diagnosed with CHD. CHDs were distributed equally in patients with mild or severe CARMs. Patients with multiple congenital abnormalities were more frequently diagnosed with CHD (n = 16, 36%) than patients without multiple congenital malformations (n = 5, 9%, P = .001). Patients with CARM diagnosed with CHD using pediatric cardiac echo screening were younger than 3 months of age at diagnosis. Earlier general pediatric examinations missed 7 (50%) children with mild and 4 (50%) with severe CHDs. CONCLUSIONS: The severity of CARM could predict neither prevalence nor severity of CHD. More than one-half of CHDs were missed during the first physical examination. No new CHDs were found in patients older than 3 months of age at the time CARMs were diagnosed. We recommend screening all patients with CARM younger than 3 months of age for CHD at the time CARM is diagnosed. Preoperative echocardiography should be the rule in children younger than 3 months of age and with multiple congenital anomalies. PMID- 27686586 TI - Cesarean Delivery, Overweight throughout Childhood, and Blood Pressure in Adolescence. AB - OBJECTIVES: To investigate whether children delivered by cesarean had a higher risk of being overweight from early until late childhood and whether they had a higher blood pressure in adolescence compared with children delivered vaginally. STUDY DESIGN: We used data from a Dutch birth cohort study with prenatal inclusion in 1996 and 1997. Mode of delivery (cesarean or vaginal delivery) was ascertained at 3 months after birth by questionnaire. During clinical examinations, height and weight (at age 4, 8, 12, and 16 years) and blood pressure (at age 12 and 16 years) were measured. We used mixed model analysis to estimate associations of cesarean delivery with overweight and blood pressure z scores in 2641 children who participated in at least 1 of the 4 examinations. RESULTS: Children born by cesarean delivery (n = 236, 8.9%) had a 1.52 (95% CI 1.18, 1.96) higher odds of being overweight throughout childhood than children delivered vaginally. Children born by cesarean delivery had no higher systolic blood pressure z-score (0.11 SD, 95% CI -0.04, 0.26), nor a different diastolic blood pressure z-score (-0.00 SD, 95% CI -0.10, 0.09) in adolescence than children delivered vaginally. CONCLUSIONS: Compared with children delivered vaginally, children delivered by cesarean had a 52% higher risk of being overweight throughout childhood, but this was not accompanied by a higher blood pressure in adolescence. PMID- 27686587 TI - Risk of recurrence after a first unprovoked seizure in children. AB - OBJECTIVES: This study aimed to evaluate the first episode of unprovoked epileptic seizure in children and assess recurrence risk factors. METHODS: This was a retrospective observational study, based on the analysis of medical records of patients admitted between 2003 and 2014, with first epileptic seizure, at the pediatric service of a secondary hospital. The data were analyzed using the SPSS 20.0 program. RESULTS: Of the 103 patients, 52.4% were boys. The median age at the first seizure was 59 (1-211) months. About 93% of children were submitted to an electroencephalogram at the first episode and 47% underwent neuroimaging assessment. Treatment with an antiepileptic drug was started in 46% of patients. The recurrence rate was 38% and of these, 80% had the second seizure within six months after the first event. Of the assessed risk factors, there was a statistically significant association between seizure during sleep and recurrence (p=0.004), and between remote symptomatic etiology seizure and occurrence of new seizure (p=0.02). The presence of electroencephalogram abnormalities was also associated with the occurrence of new seizures (p=0.021). No association was found between age, duration of the seizure, and family history of epilepsy with increased risk of recurrence. CONCLUSIONS: Most children with a first unprovoked epileptic seizure had no recurrences. The risk of recurrence was higher in patients with seizure occurring during sleep or remote symptomatic ones and those with abnormal electroencephalogram results. PMID- 27686588 TI - Influence of the informal primary caretaker on glycemic control among prepubertal pediatric patients with type 1 diabetes mellitus. AB - OBJECTIVES: In prepubertal type 1 diabetic patients (DM1), the availability of an informal primary caregiver (ICP) is critical to making management decisions; in this study, the ICP-related risk factors associated with glycemic control were identified. PATIENTS, MATERIALS, AND METHODS: A comparative cross-sectional study was performed. Fifty-five patients with DM1 under the age of 11 years were included. The patient-related factors associated with glycemic control evaluated were physical activity, DM1 time of evolution, and adherence to medical indications. The ICP-related factors evaluated were education, employment aspects, depressive traits (Beck questionnaire), family functionality (family APGAR), support of another person in patient care, stress (Perceived Stress Scale), and socioeconomic status (Bronfman questionnaire). Multivariate logistic and linear regression analyses were performed. RESULTS: The patients' median age was 8 years; 29 patients had good glycemic control, and 26 were uncontrolled. The main risk factor associated with glycemic dyscontrol was stress in the ICP (OR 24.8; 95% CI 4.06-151.9, p=0.001). While, according to the linear regression analysis it was found that lower level of education (beta 0.991, 95% CI 0.238 1.743, p=0.011) and stress (beta 1.918, 95% CI 1.10-2.736, p=0.001) in the ICP, as well as family dysfunction (beta 1.256, 95% CI 0.336-2.177, p=0.008) were associated with higher levels of glycated hemoglobin. CONCLUSIONS: Level of education and stress in the ICP, as well as family dysfunction, are factors that influence the lack of controlled blood glucose levels among prepubertal DM1 patients. PMID- 27686590 TI - Pseudo-tying injuries in a hanged person. AB - A 50-year-old man was found hanged on the concrete dam of a water reservoir. The ligature, a braided rope made of synthetic fibres, was attached to a lamp on the dam crest. The length of the rope between the fastening point and the noose was about 4m. At autopsy, stretchmark-like intimal tears of the carotid arteries were found, but the full pattern of (internal) decapitation and severance of the cervical spine was not present. The right wrist showed two almost circular, ribbon-like abrasions initially suggesting that the man had been tied before hanging. When the ligature was examined, horny scales adhered to the noose, but were also detected away from the slip-knot. By means of a DNA analysis the epidermal traces could be assigned to the deceased. The overall picture of the findings suggested that the man had roped down from the dam crest with the ligature wrapped around his right wrist thus abrading the skin. PMID- 27686591 TI - A radiation oncologist's guide to contour the parotid gland. PMID- 27686592 TI - Boost delineation in breast radiation therapy: Isotropic versus anisotropic margin expansion. AB - PURPOSE: The purpose of this article is to compare isotropic and anisotropic margin expansion with regard to the size of the clinical target volume boost (CTVboost) and the interobserver variability (IOV). METHODS AND MATERIALS: Lumpectomy cavities marked with 3 or more surgical clips were delineated by 6 radiation oncologists who specialized in breast radiation therapy. CTVboost anisotropic was created by manually expanding the tumor bed with an anisotropic margin of 15 mm (20 mm in case of extensive intraductal component) minus the surgical free margins in 6 directions (anteroposterior, craniocaudal, and superoinferior). For the CTVboost isotropic, the tumor bed was enlarged with an isotropic margin of 15 mm (20 mm in case of extensive intraductal component) minus the minimal surgical free margin. The volumes of the delineated CTVboost (cm3) were measured. To assess the IOV, the Jaccard index (JI), defined as the intersection divided by the size of the union of the sample sets, was used (ideal value = 1). The JI was calculated for each case and each observer pair. Linear mixed models were used for all analyses. RESULTS: A total of 444 delineated tumor beds were evaluated. The mean volume of the CTVboost almost doubled by expanding the tumor bed with an isotropic margin compared with anisotropic margins (CTVboost isotropic 94 mL [12.5-331.0] vs CTVboost anisotropic 50 mL [3.2-332.7]; P = .0006). The IOV, assessed by the JI, significantly decreased by using isotropic versus anisotropic margin expansion (JICTV boost isotropic 0.73 [0.02 0.92] vs JICTV boost anisotropic 0.51 [0.0-0.8]; P< .0001). Because of the known positive correlation of the IOV and larger volumes, we corrected for CTVboost volumes. With this correction, the difference in IOV remains highly significant (P < .0001) in favor of isotropic margin expansion. CONCLUSIONS: The use of anisotropic margin expansion from tumorbed to CTVboost isotropic significantly reduced the volume of the delineated CTVboost with a factor of 1.9 compared with isotropic margin expansion, but it substantially increased the interobserver variability.

AB - A novel heterotrophic nitrifying fungus, defined as Penicillium sp. L1, can form mycelial pellets in liquid medium in this study. The effects of inoculation method, C/N ratio, initial pH, and temperature were gradually evaluated to improve the simultaneous removal of total nitrogen (TN) and chemical oxygen demand (COD) in wastewater by Penicillium sp. L1. Results showed that compared with spore inoculation, 48 h pellet inoculum could significantly increase the pellet size (from about 1.5 mm to 3.2 mm) and improve the removal capability, particularly for COD removal (from less than 50-86.20%). The removal efficiencies of TN and COD reached 98.38% (from 136.01 mg/L to 2.20 mg/L) and 92.40% (from 10,720 mg/L to 815 mg/L) under the following conditions: C/N 36, pH 3, 30 degrees C, and inoculation with 48 h pellets. The pellet diameter reached 4.8 mm after 4 day cultivation. In this case, Penicillium sp. L1 removed TN from 415.93 mg/L to 43.39 mg/L, as well as COD from 29,533 mg/L to 8850 mg/L. Overall, the results indicated that the pellet size was closely related to the pollutant-removal ability of Penicillium sp. L1. Furthermore, mycelial pellets (4.8 mm, dead) only adsorbed 38.08% TN (from 125.45 mg/L to 77.78 mg/L), which indicated that adsorption did not play a major role in the nitrogen-removal process. PMID- 27686593 TI - From pathogenesis to clinical application: insights into exosomes as transfer vectors in cancer. AB - Exosomes are nanoscale extracellular membrane vesicles that are created by the fusion of an intracellular multivesicular body with the cell membrane. They are widely distributed in serum, urine, saliva and other biological fluids. As important transfer vectors for intercellular communication and genetic material, exosomes can stimulate target cells directly via receptor-mediated interactions or via the transfer of various bioactive molecules, such as cell membrane receptors, proteins, mRNAs and microRNAs, thus exerting their biological functions. This review focuses on the biological characteristics of exosomes, as well as their role and underlying mechanisms of action in the evolution of tumor formation, metastasis, drug resistance and other malignant behaviors. Additionally, this review emphasizes the potential applications of exosomes in the treatment of tumors. Further research may provide new ideas and methods to establish effective, exosome-based strategies for the early diagnosis and treatment of tumors. PMID- 27686595 TI - Low-density lipoprotein transport through an arterial wall under hypertension - A model with time and pressure dependent fraction of leaky junction consistent with experiments. AB - The influence of hypertension on low-density lipoproteins intake into the arterial wall is an important factor for understanding mechanisms of atherosclerosis. It has been experimentally observed that the increased pressure leads to the higher level of the LDL inside the wall. In this paper we attempt to construct a model of the LDL transport which reproduces quantitatively experimental outcomes. We supplement the well-known four-layer arterial wall model to include two pressure induced effects: the compression of the intima tissue and the increase of the fraction of leaky junctions. We demonstrate that such model can reach the very good agreement with experimental data. PMID- 27686596 TI - Allometric scaling of electrical excitation and propagation in the mammalian heart. AB - Variations in body mass impose constraints on the structure and function of mammalian species, including those of the cardiovascular system. Numerous biological processes, including cardiovascular parameters, have been shown to scale with body mass (BM) according to the law of allometric scaling: Y=Y =a?BMb (Y, biological process; a, normalization constant; b, scaling exponent, which in many instances is a multiple of 1/4). These parameters include heart and breathing rates, intervals and subintervals of the electrocardiogram (ECG), action potential duration (APD), metabolic rate, and temporal properties of ventricular fibrillation. For instance, the hierarchical branching networks of the vascular system, and of the specialized conduction system in the heart have been proposed to be important determinants of allometric scaling. A global and unifying molecular mechanism of allometric scaling has not been put forth, but changes in gene expression have been proposed to play an important role. Even though it is accepted that differences in body size have cardiovascular effects, the use of scaling in the clinical setting is limited. An increase in the clinical utilization of scaling is thought to lead to improved cardiovascular disease diagnosis and management in patients.

PMID- 27686599 TI - Anabolic action of parathyroid hormone (PTH) does not compromise bone matrix mineral composition or maturation. AB - Intermittent administration of parathyroid hormone (PTH) is used to stimulate bone formation in patients with osteoporosis. A reduction in the degree of matrix mineralisation has been reported during treatment, which may reflect either production of undermineralised matrix or a greater proportion of new matrix within the bone samples assessed. To explore these alternatives, high resolution synchrotron-based Fourier Transform Infrared Microspectroscopy (sFTIRM) coupled with calcein labelling was used in a region of non-remodelling cortical bone to determine bone composition during anabolic PTH treatment compared with region matched samples from controls. 8week old male C57BL/6 mice were treated with vehicle or 50MUg/kg PTH, 5 times/week for 4weeks (n=7-9/group). Histomorphometry confirmed greater trabecular and periosteal bone formation and 3-point bending tests confirmed greater femoral strength in PTH-treated mice. Dual calcein labels were used to match bone regions by time-since-mineralisation (bone age) and composition was measured by sFTIRM in six 15MUm2 regions at increasing depth perpendicular to the most immature bone on the medial periosteal edge; this allowed in situ measurement of progressive changes in bone matrix during its maturation. The sFTIRM method was validated in vehicle-treated bones where the expected progressive increases in mineral:matrix ratio and collagen crosslink type ratio were detected with increasing bone maturity. We also observed a gradual increase in carbonate content that strongly correlated with an increase in longitudinal stretch of the collagen triple helix (amide I:amide II ratio). PTH treatment did not alter the progressive changes in any of these parameters from the periosteal edge through to the more mature bone. These data provide new information about how the bone matrix matures in situ and confirm that bone deposited during PTH treatment undergoes normal collagen maturation and normal mineral accrual. PMID- 27686600 TI - Variants of HSD11B2 gene in hypertensive disorders of pregnancy. AB - INTRODUCTION: One of the hypotheses concerning the etiology of gestational hypertension (GH) and pre-eclampsia (PE) assumes that they develop as a result of placenta malfunctioning at the early stage of pregnancy. Placental dysfunction is also associated with the decreased activity of 11beta-hydroxysteroid dehydrogenase 2 (11beta-HSD2), which in normal pregnancy protects the fetus from the excess of maternal cortisol. OBJECTIVE: The aim of the study was to analyze the sequence of HSD11B2, a gene that encodes 11beta-HSD2, searching for mutations and haplotypes associated with the increased risk of GH or PE. Those may serve as potential genetic markers of GH and PE. METHODS: The study was performed in case control structure and included pregnant women (in third trimester) diagnosed with: GH, PE or being normotensive (control group). The research comprised DNA sequencing of HSD11B2, followed by restriction analysis (PCR-RFLP). The linkage disequilibrium analysis and haplotype-based case-control analysis were performed. RESULTS: Six sequence variations were observed. Four mutations were indicated in the coding region of HSD11B2 and the other two in 3'-UTR. Two SNPs: c.468C > A and c.534G > A were found to be in total disequilibrium. CONCLUSIONS: High variability in HSD11B2 sequence was indicated in the study population, but the relevance of observed SNPs to GH or PE development was not confirmed.

PMID- 27686598 TI - The regulation of iron metabolism by hepcidin contributes to unloading-induced bone loss. AB - Iron overload inhibits osteoblast function and promotes osteoclastogenesis. Hepcidin plays an important role in this process. The changes in iron content and the regulation of hepcidin under unloading-induced bone loss remain unknown. A hindlimb suspension model was adopted to simulate unloading-induced bone loss in mice. The results showed that iron deposition in both liver and bone was markedly increased in hindlimb unloaded mice, and was accompanied by the upregulation of osteoclast activity and downregulation of osteoblast activity. The iron chelator deferoxamine mesylate (DFO) reduced the iron content in bone and alleviated unloading-induced bone loss. The increased iron content in bone was mainly a result of the upregulation of transferrin receptor 1 (TfR1) and divalent metal transporter 1 with iron response element (DMT1+IRE), rather than changes in the iron transporter ferroportin 1 (FPN1). The hepcidin level in the liver was significantly higher, while the FPN1 level in the duodenum was substantially reduced. However, there were no changes in the FPN1 level in bone tissue. During hindlimb unloading, downregulation of hepcidin by siRNA increased iron uptake in bone and liver, which aggravated unloading-induced bone loss. In summary, these data show that unloading-induced bone loss was orchestrated by iron overload and coupled with the regulation of hepcidin by the liver. PMID- 27686602 TI - Association of recipient age and causes of heart transplant mortality: Implications for personalization of post-transplant management-An analysis of the International Society for Heart and Lung Transplantation Registry. AB - BACKGROUND: Survival beyond 1 year after heart transplantation has remained without significant improvement for the last 2 decades. A more individualized approach to post-transplant care could result in a reduction of long-term mortality. Although recipient age has been associated with an increased incidence of certain post-transplant morbidities, its effect on cause-specific mortality has not been established. METHODS: We analyzed overall and cause-specific mortality of heart transplant recipients registered in the International Society for Heart and Lung Transplantation Registry between 1995 and 2011. Patients were grouped by recipient age: 18 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, and >= 70 years. Multivariable regression models were used to examine the association between recipient age and leading causes of post-transplant mortality. We also compared immunosuppression (IS) use among the different recipient age groups. RESULTS: There were 52,995 recipients (78% male; median age [5th, 95th percentile]: 54 [27, 66] years). Survival through 10 years after transplant was lower in heart transplant recipients in the 2 more advanced age groups: 49% for 60 to 69 years and 36% for >= 70 years (p < 0.01 for pairwise comparisons with remaining groups). The risk of death caused by acute rejection (hazard ratio [HR], 4.11; p < 0.01), cardiac allograft vasculopathy (HR, 2.85; p < 0.01), and graft failure (HR, 2.29; p < 0.01) was highest in the youngest recipients (18-29 years) compared with the reference group (50-59 years). However, the risk of death caused by infection (HR, 2.10; p < 0.01) and malignancy (HR, 2.23; p < 0.01) was highest in older recipients (>= 70 years). Similarly, the risk of death caused by renal failure was lower in younger recipients than in the reference group (HR, 0.53; p < 0.01 for 18-49 years vs 50-59 years). The use of induction IS was similar among the different recipient age groups, and differences in maintenance IS were not clinically important. CONCLUSIONS: Causes of death in this large cohort of heart transplant recipients varied significantly with recipient age at the time of transplant, with cause-specific mortality profiles suggesting a possible effect of inadequate IS in younger recipients and over-IS in older recipients. Thus, a more personalized approach, possibly including different IS strategies according to recipient age, might result in improved post transplant survival. PMID- 27686603 TI - Facile ratiometric fluorapatite nanoprobes for rapid and sensitive bacterial spore biomarker detection. AB - Since bacterial spores, such as Bacillus anthracis spores, are extremely hazardous to human beings and animals, efforts have focused on the development of bacterial spore detector with rapid response and high selectivity and sensitivity. Therefore, we reported a facile one-step chelating-reagent-assisted hydrothermal synthesis of lanthanide-doped fluorapatite (FA) nanoprobes for detecting the biomarker of bacterial spores. In FA synthesis, ethylenediaminetetraacetic acid (EDTA) can serve not only as a shape controller and a stabilizer but also as a chelating reagent for lanthanide ions. After the fabrication, terbium (or europium) ions were not only embedded into lattice models of FA nanocrystals, but also chelated by EDTA on the surface of the FA nanocrystals, which can be available for detecting the biomarker (i.e., dipicolinic acid) of bacterial spores. The obtained FA: Ln-EDTA nanoprobes can provide reference fluorescence which play crucial roles in the calibration and correction of concentration. The fluorescence intensities of FA: Tb-EDTA or FA: Eu-EDTA from Tb3+ or Eu3+ emission were highly sensitive and increased gradually with increasing DPA concentrations. The limit of detection of FA: Tb-EDTA was 8.2nM, which is lower than that of FA: Eu-EDTA (20.9nM). It can be attributed to the fact that DPA can achieve a more effective energy transfer to Tb3+ than to Eu3+. Additionally, the nanoprobes were successfully applied for the determination of DPA in fetal calf serum samples. Given their rapid response and high sensitivity and selectivity, these ratiometric fluorescent nanoprobes are promising tools for the detection of bacterial spores. PMID- 27686605 TI - A unique iridium(III) complex-based chemosensor for multi-signal detection and multi-channel imaging of hypochlorous acid in liver injury. AB - Although hypochlorous acid (HOCl) has long been associated with a number of inflammatory diseases in mammalian bodies, the functions of HOCl in specific organs at abnormal conditions, such as liver injury, remain unclear due to its high reactivity and the lack of effective methods for its detection. Herein, a unique Ir(III) complex-based chemosensor, Ir-Fc, was developed for highly sensitive and selective detection of HOCl. Ir-Fc was designed by incorporating a ferrocene (Fc) quencher to a Ir(III) complex through a HOCl-responsive linker. In the presence of HOCl, the fast cleavage of Fc moiety in less than 1s led to the enhancement of photoluminescence (PL) and electrochemical luminescence (ECL), by which the concentration of HOCl was determined by both PL and ECL analysis. Taking advantages of excellent properties of Ir(III) complexes, optical and electrochemical analyses of the response of Ir-Fc towards HOCl were fully investigated. Followed by the measurements of low cytotoxicity of Ir-Fc by MTT analysis, one-photon (OP), two-photon (TP) and lifetime imaging experiments were conducted to visualise the generation of HOCl in live microphage and HepG2 cells, and in zebrafish and mouse, respectively. Furthermore, the generation and distribution of HOCl in liver cells and liver injury of zebrafish and mouse were investigated. The results demonstrated the applicability of Ir-Fc as an effective chemosensor for imaging of HOCl generation in mitochondria of cells and liver injury in vivo, implying the potential of Ir-Fc for biomedical diagnosis and monitoring applications. PMID- 27686604 TI - Nanostructured cobalt phosphates as excellent biomimetic enzymes to sensitively detect superoxide anions released from living cells. AB - Monitoring superoxide anion radicals in living cells has been attracting much academic and industrial interest due to the dual roles of the radicals. Herein, we synthesized a novel nanostructured cobalt phosphate nanorods (Co3(PO4)2 NRs) with tunable pore structure using a simple and effective micro-emulsion method and explored their potential utilization in the electrochemical sensing of superoxide anions. As an analytical and sensing platform, the nanoscale biomimetic enzymes Co3(PO4)2 NRs exhibited excellent selectivity and sensitivity towards superoxide anion (O2*-) with a low detection limit (2.25nM), wide linear range (5.76-5396nM), and long-term stability. Further, the nanoscale biomimetic enzyme could be efficiently applied in situ to electrochemically detect O2*- released from human malignant melanoma cells and normal keratinocyte, showing excellent real time quantitative detection capability. This material open up exciting opportunities for implementing biomimetic enzymes in nanoscale transition metal phosphates and designing enzyme-free biosensors with much higher sensitivity and durability in health and disease analysis than those of natural one. PMID- 27686606 TI - Direct determination of small RNAs using a biotinylated polythiophene impedimetric genosensor. AB - Herein, direct determination of small RNAs is described using a functional polymer modified genosensor. The analytical strategy adopted involves deposition by electropolymerization of biotinylated polythiophene films on the surface of miniaturized, disposable, gold screen-printed electrodes, followed by the layer by-layer deposition of streptavidin, and then biotynilated capture probes. A small RNA (miR-221) target was determined via the impedimetric measurement of the hybridization event in a label-free and PCR-free approach. Under optimized conditions, the limit of detection (LOD) was 0.7 pM miR-221 (15% RSD). The genosensor was applied for determination of miR-221 in total RNA extracted from human lung and breast cancer cell lines, discriminating between the cancer positive and -negative cells, without any amplification step, in less than 2h. PMID- 27686607 TI - Lipid content and fatty acid profile during lake whitefish embryonic development at different incubation temperatures. AB - Lipids serve as energy sources, structural components, and signaling molecules during fish embryonic development, and utilization of lipids may vary with temperature. Embryonic energy utilization under different temperatures is an important area of research in light of the changing global climate. Therefore, we examined percent lipid content and fatty acid profiles of lake whitefish (Coregonus clupeaformis) throughout embryonic development at three incubation temperatures. We sampled fertilized eggs and embryos at gastrulation, eyed and fin flutter stages following chronic incubation at temperatures of 1.8, 4.9 and 8.0 degrees C. Hatchlings were also sampled following incubation at temperatures of 3.3, 4.9 and 8.0 degrees C. Fertilized eggs had an initial high percentage of dry mass composed of lipid (percent lipid content; ~29%) consisting of ~20% saturated fatty acids (SFA), ~32% monounsaturated fatty acids (MUFA), ~44% polyunsaturated fatty acids (PUFA), and 4% unidentified. The most abundant fatty acids were 16:0, 16:1, 18:1(n-9c), 20:4(n-6), 20:5(n-3) and 22:6(n-3). This lipid profile matches that of other cold-water fish species. Percent lipid content increased during embryonic development, suggesting protein or other yolk components were preferentially used for energy. Total percentage of MUFA decreased during development, which indicated MUFA were the primary lipid catabolized for energy during embryonic development. Total percentage of PUFA increased during development, driven largely by an increase in 22:6(n-3). Temperature did not influence percent lipid content or percent MUFA at any development stage, and had inconsistent effects on percent SFA and percent PUFA during development. Thus, lake whitefish embryos appear to be highly adapted to low temperatures, and do not alter lipids in response to temperature within their natural incubation conditions. PMID- 27686608 TI - Creation of an apoptin-derived peptide that interacts with SH3 domains and inhibits glioma cell migration and invasion. AB - Glioblastoma multiforme (GBM) is an aggressive tumor of the central nervous system characterized by high rates of recurrence, morbidity, and mortality. This study investigated the antitumor effects of an apoptin-derived peptide (ADP) on glioma cells and explored the underlying mechanisms. The U251, U87, and C6 glioma cell lines were used in the present study, and the expression of p-Akt, Akt, and MMP-9 was determined through Western blotting, quantitative real-time PCR, and hematoxylin and eosin (HE) staining. Tumor growth was evaluated by magnetic resonance imaging, and cell viability was assessed through an 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide MTT assay. Glioma cell metastasis was evaluated using transwell migration, invasion, and scratch-wound assays. An ADP was designed and synthesized based on the results of a domain based analysis of the structure of apoptin. The ADP inhibited glioma cell viability, invasion and migration, and treatment with the synthesized ADP led to downregulation of p-Akt and MMP-9 and inhibited MMP-9 translation. The ADP also inhibited glioma invasion and migration in vivo, and HE staining showed decreases in the satellite-like invasion of cell masses and apoptotic cell populations after treatment with the ADP. Our findings demonstrate that treatment with an ADP can suppress glioma cell migration and invasion via the PI3K/Akt/MMP-9 signaling pathway and provide a new platform for the development of drugs for treating glioma. PMID- 27686609 TI - Colistin versus polymyxin B for the treatment of patients with multidrug resistant Gram-negative infections: a systematic review and meta-analysis. AB - Colistin and polymyxin B (PMB) have different pharmacokinetic profiles and minor differences in antimicrobial activities that may result in discrepancies in mortality and nephrotoxicity. A systematic review and meta-analysis was conducted. PubMed, Scopus and Cochrane Library databases were searched. There was no significant difference in unadjusted mortality between patients treated with colistin and PMB [risk ratio (RR) = 0.71, 95% confidence interval (CI) 0.45 1.13]. Adjusted data were not available. Unadjusted nephrotoxicity was more common in patients treated with colistin than PMB (RR = 1.55, 95% CI 1.36-1.78). According to the RIFLE (Risk, Injury, Failure, Loss of kidney function, and End stage kidney disease) criteria, there was no difference regarding risk, injury or failure between colistin and PMB. Although episodes of loss of renal function were few in general, they developed primarily in colistin-treated patients (RR = 8.55, 95% CI 1.48-49.49). Colistin was associated with more episodes of nephrotoxicity that also occurred sooner in the analysis of adjusted data (hazard ratio = 2.16, 95% CI 1.43-3.27). Colistin administration was an independent risk factor for nephrotoxicity in two studies. Future studies should evaluate in depth the factors associated with mortality and nephrotoxicity in patients treated with polymyxins and the impact of polymyxin-associated nephrotoxicity on mortality.

PMID- 27686611 TI - Searching and synthesising 'grey literature' and 'grey information' in public health: critical reflections on three case studies. AB - BACKGROUND: Grey literature includes a range of documents not controlled by commercial publishing organisations. This means that grey literature can be difficult to search and retrieve for evidence synthesis. Much knowledge and evidence in public health, and other fields, accumulates from innovation in practice. This knowledge may not even be of sufficient formality to meet the definition of grey literature. We term this knowledge 'grey information'. Grey information may be even harder to search for and retrieve than grey literature. METHODS: On three previous occasions, we have attempted to systematically search for and synthesise public health grey literature and information-both to summarise the extent and nature of particular classes of interventions and to synthesise results of evaluations. Here, we briefly describe these three 'case studies' but focus on our post hoc critical reflections on searching for and synthesising grey literature and information garnered from our experiences of these case studies. We believe these reflections will be useful to future researchers working in this area. RESULTS: Issues discussed include search methods, searching efficiency, replicability of searches, data management, data extraction, assessing study 'quality', data synthesis, time and resources, and differentiating evidence synthesis from primary research. CONCLUSIONS: Information on applied public health research questions relating to the nature and range of public health interventions, as well as many evaluations of these interventions, may be predominantly, or only, held in grey literature and grey information. Evidence syntheses on these topics need, therefore, to embrace grey literature and information. Many typical systematic review methods for searching, appraising, managing, and synthesising the evidence base can be adapted for use with grey literature and information. Evidence synthesisers should carefully consider the opportunities and problems offered by including grey literature and information. Enhanced incentives for accurate recording and further methodological developments in retrieval will facilitate future syntheses of grey literature and information. PMID- 27686612 TI - Plasma CTGF is independently related to an increased risk of cardiovascular events and mortality in patients with atherosclerotic disease: the SMART study. AB - AIMS: Connective tissue growth factor (CTGF) plays a key role in tissue fibrogenesis and growing evidence indicates a pathogenic role in cardiovascular disease. Aim of this study is to investigate the association of connective tissue growth factor (CTGF/CCN2) with cardiovascular risk and mortality in patients with manifest vascular disease. METHODS AND RESULTS: Plasma CTGF was measured by ELISA in a prospective cohort study of 1227 patients with manifest vascular disease (mean age 59.0 +/- 9.9 years). Linear regression analysis was performed to quantify the association between CTGF and cardiovascular risk factors. Results are expressed as beta (beta) regression coefficients with 95% confidence intervals (CI). The relation between CTGF and the occurrence of new cardiovascular events and mortality was assessed with Cox proportional hazard analysis. Adjustments were made for potential confounding factors. Plasma CTGF was positively related to total cholesterol (beta 0.040;95%CI 0.013-0.067) and LDL cholesterol (beta 0.031;95%CI 0.000-0.062) and inversely to glomerular filtration rate (beta -0.004;95%CI -0.005 to -0.002). CTGF was significantly lower in patients with cerebrovascular disease. During a median follow-up of 6.5 years (IQR 5.3-7.4) 131 subjects died, 92 experienced an ischemic cardiac complication and 45 an ischemic stroke. CTGF was associated with an increased risk of new vascular events (HR 1.21;95%CI 1.04-1.42), ischemic cardiac events (HR 1.41;95%CI 1.18-1.67) and all-cause mortality (HR 1.18;95%CI 1.00-1.38) for every 1 nmol/L increase in CTGF. No relation was observed between CTGF and the occurrence of ischemic stroke. CONCLUSIONS: In patients with manifest vascular disease, elevated plasma CTGF confers an increased risk of new cardiovascular events and all-cause mortality. PMID- 27686614 TI - Somatostatin regulates NHE8 protein expression via the ERK1/2 MAPK pathway in DSS induced colitis mice. AB - Previous studies reported that administration of somatostatin (SST) to human patients mitigated their diarrheal symptoms. Octreotide (an analog of SST) treatment in animals resulted in upregulation of sodium/hydrogen exchanger 8 (NHE8). NHE8 is important for water/sodium absorption in the intestine, and loss of NHE8 function results in mucosal injury. Thus we hypothesized that NHE8 expression is inhibited during colitis and that SST treatment during pathological conditions can restore NHE8 expression. Our data showed for the first time that NHE8 is expressed in the human colonic tissue and that NHE8 expression is decreased in ulcerative colitis (UC) patients. We also found that octreotide could stimulate colonic NHE8 expression in colitic mice. Furthermore, the somatostatin receptor 2 (SSTR2) agonist seglitide and the somatostatin receptor 5 (SSTR5) agonist L-817,818 could restore NHE8 expression via its role in suppressing ERK1/2 phosphorylation. Our study uncovered a novel mechanism of SST stimulation of NHE8 expression in colitis. PMID- 27686613 TI - Comprehensive analysis of microRNA signature of mouse pancreatic acini: overexpression of miR-21-3p in acute pancreatitis. AB - In the current study, we have characterized the global miRNA expression profile in mouse pancreatic acinar cells and during acute pancreatitis using next generation RNA sequencing. We identified 324 known and six novel miRNAs that are expressed in mouse pancreatic acinar cells. In the basal state, miR-148a-3p, miR 375-3p, miR-217-5p, and miR-200a-3p were among the most abundantly expressed, whereas miR-24-5p and miR-421-3p were the least abundant. Treatment of acinar cells with caerulein (100 nM) and taurolithocholic acid 3-sulfate [TLC-S (250 MUM)] induced numerous changes in miRNA expression profile. In particular, we found significant overexpression of miR-21-3p in acini treated with caerulein and TLC-S. We further looked at the expression of miR-21-3p in caerulein, l-arginine, and caerulein + LPS-induced acute pancreatitis mouse models and found 12-, 21-, and 50-fold increased expression in the pancreas, respectively. In summary, this is the first comprehensive analysis of global miRNA expression profile of mouse pancreatic acinar cells in normal and disease conditions. Our analysis shows that miR-21-3p expression level correlates with the severity of the disease. PMID- 27686616 TI - Optimizing ankle performance when taped: Effects of kinesiology and athletic taping on proprioception in full weight-bearing stance. AB - OBJECTIVES: To explore the effects of kinesiology taping (KT) and athletic taping (AT) on ankle proprioception when tested in functional, full weight-bearing stance. DESIGN: Cross-sectional study. METHODS: Twenty-four healthy university students participated. Proprioception was measured using the Active Movement Extent Discrimination Apparatus (AMEDA). The three testing conditions: no-taping, KT, AT, and foot tested were randomly assigned. Perceived comfort, support and proprioceptive performance under two taping conditions were recorded. RESULTS: Proprioceptive discrimination scores with 95% CIs for no-taping, KT and AT were 0.81 (0.79-0.84), 0.81 (0.79-0.83), and 0.79 (0.77-0.81). Repeated measures ANOVA showed neither any significant difference associated with taping compared with no taping (p=0.30), nor any difference between KT and AT (p=0.19). The group was then divided, according to their no-taping scores, into two sub-groups: with scores below the no-taping mean (n=13), and above the mean (n=11). ANOVA revealed a significant interaction (p=0.008) indicating that above-average no-taping performers proprioception scores were worse when taped, whereas below-average performers improved. For both KT and AT, only ratings of perceived comfort when taped were significantly associated with actual proprioceptive performance (both r>0.44, p<=0.03). Other perception ratings (support and performance) were significantly inter-correlated (both r>0.42, p<0.04), but neither was significantly correlated with actual performance (both p>0.31). CONCLUSIONS: Taping of the foot and ankle may amplify sensory input in a way that enhances proprioception of poor performers but produces an input overload that impairs proprioception in those who originally performed well when no-taping.

AB - The magnetic mesoporous silica of magMCM-41 with large surface area (695 m2 g-1) and high magnetization (10.79 emu g-1) was synthesized using extracted amorphous silica from rice husk. The synthesized materials were applied for adsorption of Cd(II) ions from aqueous solution in batch operation systems. A highly selective adsorbent was obtained by grafting 3-aminopropyltrimethoxysilane on the pores of the magMCM-41 in which the adsorption capacity of Cd(II) ions increased from 41.8 to 86 mg g-1, under the same conditions. A total of 20 sets of experiments were planned by the central composite design under response surface methodology. The effects of three independent variables pH, initial Cd(II) ion concentration and sorbent dosage were investigated on the adsorption capacity (qe) and removal efficiency (R) of cadmium. The best responses for Cd(II) adsorption capacity and removal efficiency were 493.21 mg g-1 and 60.25%, respectively, which was achieved at pH of 5.05, sorbent dosage of 0.1 g L-1 and Cd(II) concentration of 150 mg L-1. Additionally, the obtained value for desirability was equal to 0.807. The theoretical isotherm models were applied to describe the adsorption process that the Langmuir model provides the best correlation of the equilibrium data. The kinetics study revealed that data from the experiments fitted well to the pseudo-second-order equation than the pseudo-first-order equation. The thermodynamic parameters revealed that the adsorption process strongly depended on temperature and indicated the exothermic behavior and spontaneous nature of the adsorption.

AB - Alcoholic liver disease (ALD) and nonalcoholic fatty liver disease (NAFLD) represent a major health burden in industrialized countries. Although alcohol abuse and nutrition play a central role in disease pathogenesis, preclinical models support a contribution of the gut microbiota to ALD and NAFLD. This review describes changes in the intestinal microbiota compositions related to ALD and NAFLD. Findings from in vitro, animal, and human studies are used to explain how intestinal pathology contributes to disease progression. This review summarizes the effects of untargeted microbiome modifications using antibiotics and probiotics on liver disease in animals and humans. While both affect humoral inflammation, regression of advanced liver disease or mortality has not been demonstrated. This review further describes products secreted by Lactobacillus- and microbiota-derived metabolites, such as fatty acids and antioxidants, that could be used for precision medicine in the treatment of liver disease. A better understanding of host-microbial interactions is allowing discovery of novel therapeutic targets in the gut microbiota, enabling new treatment options that restore the intestinal ecosystem precisely and influence liver disease. The modulation options of the gut microbiota and precision medicine employing the gut microbiota presented in this review have excellent prospects to improve treatment of liver disease. PMID- 27686621 TI - MiR-4500 is epigenetically downregulated in colorectal cancer and functions as a novel tumor suppressor by regulating HMGA2. AB - This study aimed to understand the exact function and potential mechanism of miR 4500 in colorectal cancer (CRC). In this study, the expression of miR-4500 was decreased in both CRC cells and tissues, and downregulated miR-4500 indicated advanced tumor stage and poor survival. By bisulfite sequencing analysis, we found that the CpG island in the promoter region of miR-4500 was hypermethylated in CRC cells and tissues compared with normal control cells and non-tumor tissues, respectively. Functionally, gain- and loss-of-function analyses indicated the tumor suppressor role of miR-4500: it suppressed cell proliferation, cell cycle progression, migration, and invasion. Predictive algorithms and experimental analyses identified HMGA2 as a direct target of miR 4500. Reintroducing HMGA2 impaired the inhibitory effects of miR-4500 on cell growth and motility. Clinically, higher HMGA2 protein expression in CRC tissues was associated with advanced tumor stage and poor survival. An inverse correlation was found between miR-4500 levels and HMGA2 protein expression. Taken together, this study provides the first evidence that miR-4500 functions as a novel tumor suppressor in the miR-4500/HMGA2 axis in colorectal carcinogenesis, and restoring miR-4500 expression might represent a promising therapeutic strategy for CRC. PMID- 27686622 TI - Adhesive ligand tether length affects the size and length of focal adhesions and influences cell spreading and attachment. AB - Cells are known to respond to physical cues from their microenvironment such as matrix rigidity. Discrete adhesive ligands within flexible strands of fibronectin connect cell surface integrins to the broader extracellular matrix and are thought to mediate mechanosensing through the cytoskeleton-integrin-ECM linkage. We set out to determine if adhesive ligand tether length is another physical cue that cells can sense. Substrates were covalently modified with adhesive arginylglycylaspartic acid (RGD) ligands coupled with short (9.5 nm), medium (38.2 nm) and long (318 nm) length inert polyethylene glycol tethers. The size and length of focal adhesions of human foreskin fibroblasts gradually decreased from short to long tethers. Furthermore, we found cell adhesion varies in a linker length dependent manner with a remarkable 75% reduction in the density of cells on the surface and a 50% reduction in cell area between the shortest and longest linkers. We also report the interplay between RGD ligand concentration and tether length in determining cellular spread area. Our findings show that without varying substrate rigidity or ligand density, tether length alone can modulate cellular behaviour. PMID- 27686623 TI - Non-specific alarm calls trigger mobbing behavior in Hainan gibbons (Nomascus hainanus). AB - Alarm calls are important defensive behaviors. Here, we report the acoustic spectrum characteristics of alarm calls produced by Hainan gibbons (Nomascus hainanus) inhabiting Bawangling National Nature Reserve in Hainan, China. Analysis of call data collected from 2002-2014 shows that alarm calls are emitted by all family group members, except infants. Alarm behavior included simple short alarming calls (7-10 min) followed by longer variable-frequency mobbing calls lasting 5-12 min. The duration of individual alarming and mobbing calls was 0.078 +/- 0.014 s and 0.154 +/- 0.041 s at frequency ranges of 520-1000 Hz and 690-3920 Hz, respectively. Alarming call duration was positively associated with group size. The alarm calls can trigger mobbing behavior in Hainan gibbons; this is a defense way of social animals, and first report among the primates' species. The system of vocal alarm behavior described in this critically endangered species is simple and effective. PMID- 27686624 TI - SCOP/PHLPP1beta mediates circadian regulation of long-term recognition memory. AB - Learning and memory depend on the time of day in various organisms, but it is not clear whether and how the circadian clock regulates memory performance. Here we show that consolidation of long-term recognition memory is a circadian-regulated process, which is blunted by disruption of the hippocampal clock. We focused on SCOP, a key molecule regulating hippocampus-dependent long-term memory for objects. The amounts of SCOP and its binding partner K-Ras in the hippocampal membrane rafts exhibit robust circadian changes, and SCOP knockdown in the hippocampal CA1 impairs long-term memory at night. Circadian changes in stimulus dependent activation of ERK in the hippocampal neurons are dependent on the SCOP levels in the membrane rafts, while Scop knockout abrogates the activation rhythm. We conclude that long-term memory formation is regulated by the circadian clock through SCOP dynamics in the membrane rafts of the hippocampal CA1. PMID- 27686625 TI - Exosomes derived from MSCs ameliorate retinal laser injury partially by inhibition of MCP-1. AB - Although accumulated evidence supports the notion that mesenchymal stem cells (MSCs) act in a paracrine manner, the mechanisms are still not fully understood. Recently, MSC-derived exosomes (MSC-Exos), a type of microvesicle released from MSCs, were thought to carry functional proteins and RNAs to recipient cells and play therapeutic roles. In the present study, we intravitreally injected MSCs derived from either mouse adipose tissue or human umbilical cord, and their exosomes to observe and compare their functions in a mouse model of laser-induced retinal injury. We found that both MSCs and their exosomes reduced damage, inhibited apoptosis, and suppressed inflammatory responses to obtain better visual function to nearly the same extent in vivo. Obvious down-regulation of monocyte chemotactic protein (MCP)-1 in the retina was found after MSC-Exos injection. In vitro, MSC-Exos also down-regulated MCP-1 mRNA expression in primarily cultured retinal cells after thermal injury. It was further demonstrated that intravitreal injection of an MCP-1-neutralizing antibody promoted the recovery of retinal laser injury, whereas the therapeutic effect of exosomes was abolished when MSC-Exos and MCP-1 were administrated simultaneously. Collectively, these results suggest that MSC-Exos ameliorate laser-induced retinal injury partially through down-regulation of MCP-1.

PMID- 27686626 TI - PLGA nanoparticle encapsulation reduces toxicity while retaining the therapeutic efficacy of EtNBS-PDT in vitro. AB - Photodynamic therapy regimens, which use light-activated molecules known as photosensitizers, are highly selective against many malignancies and can bypass certain challenging therapeutic resistance mechanisms. Photosensitizers such as the small cationic molecule EtNBS (5-ethylamino-9-diethyl aminobenzo[a]phenothiazinium chloride) have proven potent against cancer cells that reside within acidic and hypoxic tumour microenvironments. At higher doses, however, these photosensitizers induce "dark toxicity" through light-independent mechanisms. In this study, we evaluated the use of nanoparticle encapsulation to overcome this limitation. Interestingly, encapsulation of the compound within poly(lactic-co-glycolic acid) (PLGA) nanoparticles (PLGA-EtNBS) was found to significantly reduce EtNBS dark toxicity while completely retaining the molecule's cytotoxicity in both normoxic and hypoxic conditions. This dual effect can be attributed to the mechanism of release: EtNBS remains encapsulated until external light irradiation, which stimulates an oxygen-independent, radical mediated process that degrades the PLGA nanoparticles and releases the molecule. As these PLGA-encapsulated EtNBS nanoparticles are capable of penetrating deeply into the hypoxic and acidic cores of 3D spheroid cultures, they may enable the safe and efficacious treatment of otherwise unresponsive tumour regions. PMID- 27686628 TI - Synthesis of maltodextrin-grafted-cinnamic acid and evaluation on its ability to stabilize anthocyanins via microencapsulation. AB - In this work, maltodextrin-grafted-cinnamic acid (MD-g-CA) was synthesised and used as wall material to improve the stability of purple sweet potato anthocyanins (PSPa) via microencapsualtion. MD-g-CA was prepared through esterification in a two-step convenient synthesis procedure and characterised using infra-red (IR) spectroscopy. The IR data indicated the typical ester carbonyl stretching at around 1721 cm-1. Moreover, MD-g-CA could give about 40% inhibition of DPPH radical and present excellent UV-absorption, which were notably better than that of native MD. Maltodextrin (MD) and MD-g-CA were used to prepare PSPa microcapsules by spray drying. The stability of PSPa was evaluated by UV-Vis analysis. The microcapsules produced by MD-g-CA showed a spheres-like appearance with some cracks. Storage tests revealed that the degradation rate of PSPa embedded by MD-g-CA was much lower than that of free PSPa under the same condition. Thus, MD-g-CA could be used as an effective wall material to improve stability of anthocyanins. PMID- 27686629 TI - A High-Throughput, Arbitrary-Waveform, MPI Spectrometer and Relaxometer for Comprehensive Magnetic Particle Optimization and Characterization. AB - Magnetic Particle Imaging (MPI) is a promising new tracer modality with zero attenuation deep in tissue, high contrast and sensitivity, and an excellent safety profile. However, the spatial resolution of MPI is limited to around 1 mm currently and urgently needs to be improved for clinical applications such as angiography and brain perfusion. Although MPI resolution is highly dependent on tracer characteristics and the drive waveforms, optimization is limited to a small subset of possible excitation strategies by current MPI hardware that only does sinusoidal drive waveforms at very few frequencies. To enable a more comprehensive and rapid optimization of drive waveforms for multiple metrics like resolution and signal strength simultaneously, we demonstrate the first untuned MPI spectrometer/relaxometer with unprecedented 400 kHz excitation bandwidth and capable of high-throughput acquisition of harmonic spectra (100 different drive field frequencies in only 500 ms). It is also capable of arbitrary drive-field waveforms which have not been experimentally evaluated in MPI to date. Its high throughput capability, frequency-agility and tabletop size makes this Arbitrary Waveform Relaxometer/Spectrometer (AWR) a convenient yet powerfully flexible tool for nanoparticle experts seeking to characterize magnetic particles and optimize MPI drive waveforms for in vitro biosensing and in vivo imaging with MPI. PMID- 27686630 TI - Psychometric Testing of the Self-Care of Coronary Heart Disease Inventory (SC CHDI). AB - Although coronary heart disease (CHD) requires a significant amount of self-care, there are no instruments available to measure self-care in this population. The purpose of this study was to test the psychometric properties of the Self-Care of Coronary Heart Disease Inventory (SC-CHDI). Using the Self-Care of Chronic Illness theory, we developed a 22-item measure of maintenance, management, and confidence appropriate for persons with stable CHD and tested it in a convenience sample of 392 adults (62% male, mean age 61.4 +/- 9.6 years). Factorial validity was tested with confirmatory factor analysis. Convergent validity was tested with the Medical Outcomes Study MOS-SAS Specific Adherence Scale and the Decision Making Competency Inventory (DMCI). Cronbach alpha and factor determinacy scores (FDS) were calculated to assess reliability. Two multidimensional self-care scales were confirmed: self-care maintenance included "consultative behaviors" (e.g., taking medicines as prescribed) and "autonomous behaviors" (e.g., exercising 30 minute/day; FDS = .87). The multidimensional self-care management scale included "early recognition and response" (e.g., recognizing symptoms) and "delayed response" (e.g., taking an aspirin; FDS = .76). A unidimensional confidence factor captured confidence in each self-care process (alpha = .84). All the self-care dimensions were associated with treatment adherence as measured by the MOS-SAS. Only self-care maintenance and confidence were associated with decision-making (DCMI). These findings support the conceptual basis of self-care in patients with CHD as a process of maintenance that includes both consultative and autonomous behaviors, and management with symptom awareness and response. The SC-CHDI confidence scale is promising as a measure of self-efficacy, an important factor influencing self-care. (c) 2016 Wiley Periodicals, Inc. PMID- 27686632 TI - Evidence of Trivalent Am Substitution into U3O8. AB - U3O8 is considered to be the most stable phase for uranium oxide. Its structural properties must be accurately understood to foresee and manage aspects such as its leaching behavior when spent nuclear fuel is stored in an oxidative environment. Moreover, as fuel irradiation causes the formation of fission products and activation products such as plutonium and minor actinides, it is probable that U3O8 will be mixed with other chemical elements under real conditions of oxidation. The storage issue can be extended to americium transmutation, where the irradiated compounds are mixed oxides composed of uranium and americium. This study thus focused on determining the structural properties of a solid solution containing uranium and trivalent americium (U/Am ratio = 90/10) and synthesized so as to obtain conventional U3O8 oxide. This paper presents the possibility of combining trivalent americium with uranium in a U3O8 mixed oxide for the first time, despite the high valence and atomic ratio differences, and proposes novel structural arrangements. X-ray diffraction measurements reveal americium substitution in U3O8 uranium cationic sites, leading to phase transformation into a U3O8 high-temperature structure and general lattice swelling. X-ray absorption near-edge spectroscopy and extended X ray absorption fine structure experiments highlight an excess of U+VI organized in uranyl units as the main consequence of accommodation. PMID- 27686631 TI - DNA polymerase beta decrement triggers death of olfactory bulb cells and impairs olfaction in a mouse model of Alzheimer's disease. AB - Alzheimer's disease (AD) involves the progressive degeneration of neurons critical for learning and memory. In addition, patients with AD typically exhibit impaired olfaction associated with neuronal degeneration in the olfactory bulb (OB). Because DNA base excision repair (BER) is reduced in brain cells during normal aging and AD, we determined whether inefficient BER due to reduced DNA polymerase-beta (Polbeta) levels renders OB neurons vulnerable to degeneration in the 3xTgAD mouse model of AD. We interrogated OB histopathology and olfactory function in wild-type and 3xTgAD mice with normal or reduced Polbeta levels. Compared to wild-type control mice, Polbeta heterozygous (Polbeta+/- ), and 3xTgAD mice, 3xTgAD/Polbeta+/- mice exhibited impaired performance in a buried food test of olfaction. Polbeta deficiency did not affect the proliferation of OB neural progenitor cells in the subventricular zone. However, numbers of newly generated neurons were reduced by approximately 25% in Polbeta+/- and 3xTgAD mice, and by over 60% in the 3xTgAD/Polbeta+/- mice compared to wild-type control mice. Analyses of DNA damage and apoptosis revealed significantly greater degeneration of OB neurons in 3xTgAD/Polbeta+/- mice compared to 3xTgAD mice. Levels of amyloid beta-peptide (Abeta) accumulation in the OB were similar in 3xTgAD and 3xTgAD/Polbeta+/- mice, and cultured Polbeta-deficient neurons exhibited increased vulnerability to Abeta-induced death. Olfactory deficit is an early sign in human AD, but the mechanism is not yet understood. Our findings in a new AD mouse model demonstrate that diminution of BER can endanger OB neurons, and suggest a mechanism underlying early olfactory impairment in AD.

PMID- 27686633 TI - Management of swallowing in thrombolysed stroke patients: Implementation of a new protocol. AB - PURPOSE: There is a paucity of evidence regarding dysphagia management post thrombolysis. The aim of this case-control study was to evaluate the impact of a dysphagia management protocol on patient outcomes. Thrombolysis has been completed at our metropolitan hospital since 2011 and a dysphagia management protocol was developed in 2012. METHOD: Chart auditing was completed for 83 participants in three groups: pre-protocol (n = 12) (2011), post-protocol (n = 28) (2012-2014), and non-thrombolysed stroke patients (n = 43). RESULT: Following the implementation of this clinical protocol, the average time patient remained nil by mouth reduced by 9.5 h, the percentage of patients who were malnourished or at risk reduced by 24% and the number of patients who developed aspiration pneumonia reduced by 11%. The cost of hospital stay reduced by $1505. Service compliance with best practice in dysphagia management in thrombolysed patients increased from 67% to 96% in the thrombolysed patient groups. CONCLUSION: The outcomes suggest that a clinical protocol for dysphagia management in thrombolysed patients has the potential to improve service outcomes, reduce complications from dysphagia, have financial benefits for the hospital and increase service compliance. Furthermore, the results lend support for speech pathology services to manage dysphagia on weekends. PMID- 27686635 TI - [Key issues of nephron spring surgery for renal neoplasms]. AB - In recent years the incidence of small renal carcinoma is increasing, and nephron sparing surgery(NSS) becomes the mainstream to treat it. NSS is considered based on comprehensive analysis: the imaging examination, systemic evaluation of the patients, and the indications of NSS. There are three common surgical approaches: intraperitoneal approach, retroperitoneal approach and the joint approach. It is recommended to do intraoperative frozen pathology. If the edge is positive, it is better to cut a deeper layer of the tissue around the renal tumor or transform to radical nephrectomy. Attention should also be paid to reduce heat ischemia time, in order to protect renal function and reduce postoperative renal atrophy. In addition, there are some factors, such as the accurate preoperative evaluation of renal function and surgical skill of the doctors, which can reduce the incidence of postoperative complications and improve survival and quality of life. PMID- 27686636 TI - [Effect of Sunitinib therapy on immune function of patients with advanced renal cell carcinoma]. AB - Objective: To evaluate the effect of Sunitinib therapy on immune function of patient with advanced renal cell carcinoma. Methods: A total of 27 patient with advanced renal cell carcinoma who received Sunitinib therapy in Chongqing Cancer Hospital from July 2010 to July 2014 were recruited in a prospective cohort study.Nineteen were male patients and 8 were female patients aged from 36 to 75 years with mean age of (58+/-7)years.Twenty-five cases were renal clear cell carcinoma, the other two cases were papillary renal cell carcinoma and Xp11.2 translocation renal cell carcinoma.According to MSKCC terminal prognosis scoring recommend by NCCN: 22 cases were in low risk, 5 cases were in high risk.All the patient took Sunitinib 50 mg orally once daily for 4 weeks, followed-up by 2 weeks.Flow cytometry was used to detect the levels of CD3+ , CD8+ , CD4+ T lymphocyte, NK cell and B lymphocyte in peripheral blood of patients before taking medicine.The levels of CD3+ , CD8+ , CD4+ T lymphocyte, NK cell, B lymphocyte in peripheral blood were detected again after 4 weeks, 6 weeks, 10 weeks and the disease progression.Paired t-test was used to analyze the data comparison of two groups, mean comparison in groups was conducted with repeated measurements analysis of variance, and the pairwise comparison was performed with LSD-t method. Results: The levels of CD3+ , CD8+ T lymphocyte, NK cell, B lymphocyte were significantly increased after the therapy of Sunitinib for 1 cycle(I-J was 212+/-22, 163+/-18, 59+/-12, 13.8+/-1.4, respectively, all P<0.05). The levels of CD3+ , CD8+ T lymphocyte, NK cell, B lymphocyte were significantly increased after the therapy of Sunitinib for 2 cycles(I-J was 362+/-43, 299+/-28, 91+/-19, 28.1+/-3.9, respectively, all P<0.05), while the level of CD4+ lymphocyte was decreased, but no significant difference(F=0.873, P>0.05). CD4+ /CD8+ was significantly decreased after the therapy of Sunitinib for 1 cycle, and it went on decreasing after the therapy of Sunitinib for 2 cycles(I-J was -0.31+/ 0.03, -0.44+/-0.04, respectively, all P<0.05). Disease progression occurred in 10 cases during the follow-up period.The NK cell, CD3+ , CD4+ , CD8+ T lymphocyte were significantly decreased when the disease progressed(t=2.39-5.769, all P<0.05). Conclusions: Sunitinib has effect on the immune function of patients with advanced renal cell carcinoma, and the progression of renal cell carcinoma is related to the immune function.It suggests that targeted drug therapy should be combined with biological immunotherapy, which may be the research direction for the treatment of advanced renal cell carcinoma. PMID- 27686637 TI - [Safety and efficacy of partial nephrectomy for solitary kidney tumor]. AB - Objective: To explore the safety and clinical efficacy of partial nephrectomy for solitary kidney tumor. Methods: Twenty patients with a functional or anatomic solitary kidney who underwent nephron-sparing surgery for one or more renal masses were retrospectively analyzed. There were 15 male and 5 female patients with mean age of 63 years.Patients were divided into open partial nephrectomy(OPN) group and laparoscopic partial nephrectomy(LPN) group, the two groups were followed up.Demographic and clinical characteristics were analyzed using student t-test for continuous variables, and the chi2 test for categorical variables. Results: There were 21 tumors whose maximum diameter were 1.5 to 6.0 cm, the mean size was (3.7+/-1.3)cm, mean operative time was (205.3+/ 81.8)minutes, and median estimated blood loss was 385.6 ml.Five cases accepted blood transfusion intro-operation, 1 case appeared leakage of urine post operation, none had obvious fever.Eighteen cases were clear cell carcinoma, 2 cases were chromophobe renal carcinoma, 1 case was papillary renal cell carcinoma.Seventeen cases were T1aNxM0, 3 cases were T1bNxM0, 1 case was T3NxM0.One case lost to follow up, the others had completed a mean follow-up of 21.5 months (ranging from 1 to 53 months). One case recurred, no one had metastasis, all patients were alive.The hemoglobin ((114.9+/-19.6)g/L) and estimated glomerular filtration rate(eGFR) ((46.5+/-18.2) ml/min) of postoperative day were lesser than pre-operation ((130.7+/-18.8)g/L, (58.0+/ 16.4) ml/min), while the serum creatinine was higher ((123.8+/-39.8) MUmol/L vs.(90.9+/-33.2) MUmol/L). Three months after operation, hemoglobin, serum creatinine and eGFR had no difference with pre-operative.Compared with OPN group, LPN group gain less blood loss (306 ml vs.510 ml)(t=-2.38, P=0.03), had shorter length of stays (15 d vs.21 d)(t=-3.34, P=0.04), had longer time of renal artery clamping (25.8 min vs.16.5 min)(t=2.60, P=0.02). Conclusions: Partial nephrectomy is secure and effective selection for solitary kidney tumor.The LPN has less trauma, gain less blood loss, recover faster and has shorter length of stays than the OPN, which needs shorter ischaemic time. PMID- 27686638 TI - [Transvesical single-site laparoscopic radical prostatectomy of 39 cases: technique and clinical outcomes]. AB - Objectives: To present the surgical technique of transvesical single-site laparoscopic radical prostatectomy (TVSSLRP) and to evaluate its clinical efficacy. Methods: The clinical parameters of 39 patients who underwent transvesical single-site laparoscopic radical prostatectomy in Department of Urology, Third Affiliated Hospital of Sun Yat-Sen University from November 2010 to June 2015 were retrospectively reviewed. The age was (M(QR)) 64 (10) years (range 47 to 70 years). The median preoperative serum total prostate specific antigen (PSA) level was 7.9 (2.9) MUg/L (range 4.2 to 9.8 MUg/L). The clinical TNM stage comprised 24 cases of cT1c and 15 cases of cT2a. All the transrectal biopsy Gleason score <=6. The International Index of Erectile Function (IIEF-5) was (21.7+/-1.6) points (range 18 to 24 points). The surgical procedures were performed through single-site transvesical approach. The postoperative serum PSA was regularly detected. The continence status were recorded at 1st month, 3rd month and 6th month after catheter removal, and the potencies were evaluated at 3rd month, 6th month and 12th month postoperative, respectively. Results: All the operations were successfully performed and there was no intraoperative complication or conversion to standard laparoscopic approach. The operation duration was (105+/-26) minuetes, the estimated blood loss was (100+/-56) ml and no blood transfusion was required. The pathological TNM stage comprised 30 cases of pT2a and 9 cases of pT2b, the Gleason score all <=6 and no patient had positive surgical margins. The duration of urinary catheterization was (11.6+/ 1.4) days and hospital stay was (12.9+/-4.3) days. The continence rates were 84.6%, 97.4%, 100% at 1st month, 3rd month and 6th month after catheter removal, respectively. The potency rates were 48.7%, 64.1%, 76.9% at 3rd month, 6th month and 12th month postoperative, respectively, with an IIEF-5 score>=18. Two cases demonstrated biochemical recurrence and one case presented vesico-urethral stricture during an average follow-up of 39 months (range 12 to 60 months). Conclusions: TVSSLRP is suitable for low-risk organ-confined prostate cancer. It can provide satisfactory continence and potency recovery, less complications and good oncological results. PMID- 27686639 TI - [Surgical outcomes after laparoscopy-assisted distal gastrectomy and open distal gastrectomy for patients with advanced gastric cancer: a case-control study using a propensity score method]. AB - Objective: To investigate the surgical outcomes after the laparoscopy-assisted distal gastrectomy (LADG) for patients with advanced gastric cancer. Methods: The data of 213 patients who underwent LADG and 213 treated by open distal gastrectomy (ODG) were selected using the propensity score matching method from a prospectively constructed database of 641 patients who underwent radical distal gastrectomy between January 2005 and June 2012 in Department of Gastric Surgery, Fujian Medical University Union Hospital. The baseline characteristics and surgical outcomes were compared using a paired t-test or the Wilcoxon signed ranks test for continuous variables. The cumulative survival rates were compared using the Kaplan-Meier method and log-rank test. Results: Among all patients, there were significant differences in tumor location, digestive tract reconstruction, histologic type, pT stage, and pTNM stage between LADG and ODG group (P<0.05). After propensity score matching, patient distributions were closely balanced. There was no significant difference in clinicopathologic characteristics between the two groups (P>0.05). Regarding perioperative characteristics, the time to first flatus, and time to resumption of diet, did not differ between the two groups (P>0.05), while there were significant differences in the operation time (t=-11.28, P=0.000), blood loss (t=-5.674, P=0.000), number of dissected lymph nodes (t=4.727, P=0.000), and post-operative hospital stay (t=-2.193, P=0.038). LADG group has less morbidity than ODG group (chi2=4.777, P=0.029). Multivariate analysis revealed that the laparoscopic surgery (RR=0.392, P=0.009) was the protected factor for determining postoperative complications. There was no significant difference in the cumulative survival rate at total and each UICC stage between the two groups, either (P>0.05). Conclusion: LADG is an oncological safe minimally invasive procedure for advanced gastric cancer yields comparable oncological outcomes with ODG. PMID- 27686640 TI - [Endovascular repair of primary retrograde Stanford type A aortic dissection]. AB - Objective: To summarize the short- and mid-term results on endovascular repair of primary retrograde Stanford type A aortic dissection with an entry tear in distal aortic arch or descending aorta. Methods: Between December 2009 and December 2014, 21 male patients of primary retrograde Stanford type A aortic dissection with a mean age of (52+/-9) years received endovascular repair in Department of Cardiothoracic Surgery, Jinling Hospital. Among the 21 cases, 17 patients were presented as ascending aortic intramural hematoma, 4 patients as active blood flow in false lumen and partial thrombosis, 8 patients as ulcer on descending aorta combined intramural hematoma in descending aorta, and 13 patients as typical dissection changes. All patients received endovascular stent-graft repair successfully, with 15 cases in acute phase and 6 cases in chronic phase. Results: Cone stent was implanted in 13 cases, while straight stent in 8 cases, including 1 case of left common carotid-left subclavian artery bypass surgery and 1 case of restrictive bare-metal stent implantation. No perioperative stroke, paraplegia, stent fracture or displacement, limbs or abdominal organ ischemia or other severe complications occured, except for tracheotomy in 2 patients. Active blood flow in ascending aorta or aortic arch disappeared, and intramural hematoma started being absorbed on CT angiography images before discharge. All patients were alive during follow-up (6 to 72 months), and intramural hematoma in ascending aorta and aortic arch was absorbed thoroughly. Type I endoleak and ulcer expansion were found in 1 patient, and type IV endoleak in distal stent was found in another one patient. Secondary ascending aortic dissection was found in 1 case two years later, which was cured by hybrid procedure with cardiopulmonary bypass. Conclusion: Endovascular repair of primary retrograde Stanford type A aortic dissection was safe and effective, which correlated with favorable short- and mid term results.

AB - Objective: To investigate the clinical character and treating strategy of extreme distal radial fractures. Methods: From June 2012 to May 2014, 12 patients who suffered from extreme distal radial fractures were treated in Department of Orthopedics, Tongji Hospital, Tongji University. According to AO/OTA classification, there were 4 cases of type 23B1, 3 cases of 23B2, 3 cases of 23C1 and 2 cases of 23C3.When classified by morphological features, there were 4 of simple styloid process fracture, 3 of simple extreme distal radial fracture without articular surface involved, 3 of styloid process fracture combined with distal radial articular fracture, and 2 of articular surface splintered or collapse fracture. According to the fracture features that radiographic exams showed, different surgical paths and fixation methods were chosen in order to protect soft tissues to the best advantage. To those patients with simple styloid process fracture, screw alone, Kirschner-wire or styloid plate were used for fixation. To the other types of fracture, open reduction and compound internal fixation with low-notch volar plate, dorsal or volar mini-plate, screw or Kirschner-wire was applied to ensure the stability of fixation, and maximally protect soft tissues like tendons, ligaments and neurovascular bundles, counting on the "stuffing-squeezing" effects after reduction or reconstruction of the articular surface. Situation of the wound and soft tissue were mainly checked in the first 2 weeks, and in the 3rd month post-operatively, fracture reduction and internal fixation were evaluated by radiographic methods like X-ray and CT scan. When 12 months post-operatively, not only radiographic follow-up such as fracture reduction, internal fixation and osteoarthritis were taken, but also some other evaluation, such as pain of wrist, rotation range of forearm, grip strength, and function of wrist according to DASH scores. Results: All of the 12 cases were followed up for at least 1 year. The wound healed well in all cases 2 weeks post operatively, and no soft tissue infections, necrosis or neurovascular complications occurred. All fractures healed and no loss of reduction occurred 3 months post-operatively. Internal fixations were at good condition except in 2 cases, whose Kirschner-wire had been removed 2.5 and 2.8 months after the operation due to loosening and partly backing out on dorsal side. When followed up at 12 months post-operatively, one from these 2 patients suffered from a mild pain of wrist, and grip strength together with the function of the affected wrist dramatic declined when compared to the unaffected side. With the help of radiograph, local collapse on the articular surface was found, which meant to be traumatic arthritis. There were no pain in the rest 11 cases, and flexion extension range of the wrist, rotation range of forearm and grip strength of the affected side recovered to over 80% of the unaffected side, with a DASH score was from 7 to 15 points(average 11.9 points)below 15 points. Conclusions: Traditional volar plates can not be used for extreme distal radial fractures. It may be an effective way to treat extreme distal radial fractures with compound internal fixation on the basis of morphological feature of fractures and the situation of soft tissue because of vivid of the fixation, reducing damage of soft tissue and early functional training.

AB - Objective: To evaluate the clinical effect and safety of oxycodone hydrochloride in the anesthesia for percutaneous radiofrequency ablation (PRFA) in hepatocellular carcinoma. Methods: Between March and December 2015, 60 cases of hepatocellular carcinoma patients undergoing percutaneous radiofrequency ablation surgery in Peking University Cancer Hospital were randomly divided into three groups: oxycodone group (group Q), fentanyl group (group F) and dezocine group (group D), 20 cases in each group. Respectively intravenously injection oxycodone 0.1 mg/kg, fentanyl 0.001 mg/kg, dezocine 0.1 mg/kg before surgery. After the surgeon completed puncture administer propofol to maintain anesthesia. Recorded mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), oxygen saturation (SpO2) changes in each group at entrance, beginning of radiofrequency ablation (T1), radiofrequency ablation began after 10 minutes (T2), the end of the surgical and awake. Observe the analgesia effect, respiratory depression, nausea, vomit and other complications. Postoperative pain scores were recorded.Using ANOVA, repeated measure variance analysis, SNK test, chi2 test and other tests to evaluate the anesthetic effect indexes. Results: The observation completed in all patients. Patients of three groups had no significant differences in general information. No significant difference between MAP, HR and SpO2 at each time points among the three groups. At the T1 time point (group Q: (11.7+/-1.6)/min, group D: (12.1+/-1.7)/min, group F: (10.3+/-2.3)/min, F=5.068, P=0.009) and T2 time point (group Q: (11.9+/-1.3)/min, group D: (12.2+/-1.4)/min, group F: (10.7+/-1.3)/min, F=7.024, P=0.002), RR in group F were lower than in group Q and group D. Pain visual analogue scores after waking (group Q: 0.2+/ 0.7, group D: 0.3+/-0.7, group F: 1.7+/-1.5, F=12.981, P=0.000) and postoperative pain score of 1 hour (group Q: 2.0+/-0.9, group D: 1.8+/-0.8, group F: 4.3+/-0.9, F=42.362, P=0.000) in the group Q and group D were significantly lower than in group F. The body movements in group Q and group D were significantly less than in group F (3 cases, 3 cases, 9 cases, chi2=6.400, P=0.041 ). Intraoperative respiratory depression in group Q and group D were lower than group F (3 cases, 2 cases, 9 cases, chi2=8.012, P=0.018). Conclusions: Oxycodone hydrochloride can be used safely and effectively for radiofrequency ablation. It has favorable hemodynamic stability, lower incidence of respiratory depression, and advantage in terms of postoperative pain. PMID- 27686643 TI - [The application effect of traditional monitoring and self-monitoring methods in oral anticoagulant patients with mechanical valve replacement patients: a meta analysis]. AB - Objective: To evaluate the effects of traditional monitoring and self-monitoring in patients who take the oral anticoagulation medicine after mechanical valve replacement surgical operations. Methods: A great number of Chinese and English literatures about this subject were investigated in detail, and these literatures were selected from the Cochrane Central Register of Controlled Trials, EMBase, MEDLINE, Web of Knowledge, CNKI, CBM, VIP, and WanFang Data. It should be noted that all of the literatures were published before October, 2015. Based on the results of the literature investigation, several studies were selected as the candidates. Moreover, many aspects about these candidates such as the experimental designs, characteristics of the objects of the studies and the results of the studies were filtered and recorded by two researchers independently. Furthermore, RevMan 5.3 were employed to analyze the data of the candidates. Results: Eight randomized controlled trials were studied, which included 1 262 cases in self-monitoring group and 1 198 cases in traditional monitoring group. The results of meta-analysis indicated that compared with the traditional monitoring group, lower incidence of thromboembolism (Z=3.50, P=0.000) and lower mortality (Z=4.64, P=0.000) were observed, and the bleeding difference (Z=0.07, P=0.940) had no significant statistical meaning. Moreover, compared with the traditional monitoring, the international normalized ratio (INR) of the patients who were controlled in the range of treatment of the self monitoring increased from 6% to 20.9%, and the total number of the INR tests was increased by 2.1 to 4.98 times. Conclusions: Self-monitoring could obviously reduce the possibilities of the thromboembolism and death of the patients who took the oral anticoagulation medicine after mechanical valve replacement surgical operations. Furthermore, self-monitoring could not only control the INR in the range of treatment but also increase the total number of the INR tests. In short, self-monitoring has practical value of clinical application. PMID- 27686644 TI - [New progress of castration-resistant prostate cancer immunotherapy]. AB - Prostate cancer, especially castration-resistant prostate cancer (CRPC) with its very poor prognosis, quite difficult treatments and urgent need of new theraputic strategies has become a serious problem of men's health in our country. Recent studies have shown that prostate cancer cells can stimulate the immune response; therefore, immunotherapy has become one of the hot spots in the treatment of CRPC. Cancer vaccines including polypeptide vaccines, nucleic acid vaccines, whole cell vaccines and autologous dendritic cell vaccines have been in stage II or III clinical trials, and will have good application prospects. Immune checkpoint inhibitors for the treatment of melanoma have got satisfactory results, but for CRPC are lack of systematic researches and the effects remain to be followed-up. Immune modulators for CRPC have shown antitumor activity, but the overall survival of patients was not improved. Existing studies have shown that immunotherapy of CRPC has good prospects, but most drugs are still in the research stage and need a considerable distance before clinical application. The optimal timing of immunotherapy, value of combined administration, evaluation of therapeutic effect, potential immune-based predictive and prognostic biomarkers are to be explored. With the development of tumor immune agents and the accumulation of evidence based medicine, CRPC immunotherapy will be more standard. PMID- 27686645 TI - [Recent progress in MRI-ultrasound fusion for guidance of targeted prostate biopsy]. AB - Prostate cancer is currently diagnosed by prostate biopsy performed by the transrectal ultrasound-guided technique. However, overdetection of clinical insignificant tumours and missed detection of clinical significant tumours have become problematic. MRI of the prostate, particularly if performed with multiparametric imaging, is capable of detecting clinical significant prostate cancer, which has brought the opportunity to use those images as targets for needle biopsy. Three methods of fusing MRI for targeted biopsy have been recently described: MRI-ultrasound fusion, MRI-MRI fusion ('in-bore' biopsy) and cognitive fusion. Fusion of MRI with ultrasound allows urologists to progress from blind, systematic biopsies to biopsies, which are mapped, targeted and tracked. In the future, MRI-ultrasound fusion for lesion targeting is likely to result in fewer and more accurate prostate biopsies than the present use of systematic biopsies with ultrasound guidance alone. PMID- 27686646 TI - [Progress of application for enhanced recovery after surgery in pancreaticoduodenectomy]. AB - Due to the large surgical trauma and postoperative complications, the perioperative management of pancreaticoduodenectomy has been one of the urgent problems to be solved by the surgeons. With the development of modern medicine, enhanced recovery after surgery (ERAS) comes into being, basing on anti-stress mechanism and multi-disciplinary team, and the perioperative management of pancreaticoduodenectomy has been optimized and improved continuously. The surgeons through a range of measures that had evidence-based medicine basis to mitigate the extent of surgical trauma stress, reduce the incidence of postoperative complications, shorten patient recovery time previously healthy state, and achieve maximize benefit for patients. Currently, the ERAS application in the specific aspects of pancreaticoduodenectomy remains contentious. However, with the emergence of evidence-based medicine, ERAS is constantly being refined. Therefore, this article combined with ERAS guidelines and expert consensus is of great significance to deepen the research and understanding of ERAS in pancreaticoduodenectomy. PMID- 27686648 TI - Telehealth interventions for reducing waiting lists and waiting times for specialist outpatient services: A scoping review. AB - We undertook a scoping review of the published literature to identify and summarise key findings on the telehealth interventions that influence waiting times or waiting lists for specialist outpatient services. Searches were conducted to identify relevant articles. Articles were included if the telehealth intervention restructured or made the referral process more efficient. We excluded studies that simply increased capacity. Two categories of interventions were identified - electronic consultations and image-based triage. Electronic consultations are asynchronous, text-based provider-to-provider consultations. Electronic consultations have been reported to obviate the need for face-to-face appointments between the patient and the specialist in between 34-92% of cases. However, it is often reported that electronic consultations are appropriate in less than 10% of referrals for outpatient care. Image-based triage has been used successfully to reduce unnecessary or inappropriate referrals and was used most often in dermatology, ophthalmology and otolaryngology (ENT). Reported reduction rates for face-to-face appointments by specialty were: dermatology 38-88%, ophthalmology 16-48% and ENT 89%. Image-based triage can be twice as effective as non-image based triage in reducing unnecessary appointments. Telehealth interventions can effectively be used to reduce waiting lists and improve the coordination of specialist services, and should be considered in conjunction with clinical requirements. PMID- 27686647 TI - Cutaneous nodular fasciitis with genetic analysis: a case series. AB - Nodular fasciitis is a benign self-limited myofibroblastic neoplasm, which usually involves the upper extremities and trunk of young patients. These tumors have been shown to harbor a translocation involving the MYH9 and USP6 genes, leading to overexpression of the latter. We report seven cases of nodular fasciitis with cutaneous presentations. All cases involved the dermis, with six involving the superficial subcutis, and one auricular tumor extending into cartilage. All cases showed USP6 rearrangement by fluorescence in situ hybridization; in two of three cases, the characteristic MYH9-USP6 fusion was shown by RT-PCR. All patients underwent conservative resection. Nodular fasciitis is an uncommon mesenchymal neoplasm that can occasionally present in superficial locations and is sometimes mistaken for a malignant process. Molecular testing can be useful to distinguish this entity from other cutaneous spindle cell tumors. PMID- 27686650 TI - David Oliver: Frailty in acute care. PMID- 27686649 TI - Association of Mycobacterium infections in patients with Mendelian susceptibility to mycobacterial disease with venous thromboembolism. AB - An association between a hypercoagulable state and Mendelian susceptibility to mycobacterial disease (MSMD) has been established in a few studies; resultant thrombosis is considered rare. In a case-control study, the prevalence of factor V Leiden, prothrombin G20210A and methylenetetrahydrofolate reductase (MTHFR) C677T, A1298C mutations were investigated in mycobacterium-infected patients. The study comprised 30 patients with mycobacterial infections (invasive, disseminated and/or recurrent infections with Bacille Calmette-Guerin or non-tuberculosis mycobacteria and Mycobacterium Tuberculosis with positive results for acid-fast bacilli and tuberculin skin tests) and 30 normal healthy controls. Forty female (66.7%) and 20 male subjects (33.3%) aged from 3 to 70 years were recruited into this study. Genotyping of targeted genes was performed by RT-PCR and cytokine TNF alpha concentrations were quantified using a commercially available ELISA kit. Significant associations between mycobacterial infection and TNF-alpha production after stimulating peripheral blood mononuclear cells with LPS alone and with IFN gamma plus LPS were identified. Moreover, genotyping analysis in the studied population revealed a significant association between MTHFR c.677C>T (OR, 3.28; 95% CI, 1.35-7.92; P < 0.05), MTHFR c.1298A>C (OR, 2.33; 95% CI, 1.10-4.93; P < 0.05) and mycobacterial infection in affected patients, indicating susceptibility to venous thromboembolism according to previous studies. Additionally, mycobacterium-infected patients had a significantly greater prevalence of MTHFR C677T and A1298C mutations than controls. PMID- 27686651 TI - Value of video monitoring for nocturnal seizure detection in a residential setting. AB - OBJECTIVE: Following a sudden death at a residential care unit, the Dutch Health and Care Inspectorate advised intensification of the use of video monitoring (VM) at the unit. We assessed whether VM resulted in increased identification of seizures that required clinical intervention. METHODS: The unit provides care for 340 individuals with refractory epilepsy and severe learning disabilities. Acoustic detection systems (ADSs) cover all individuals; 37 people also have a bed motion sensor (BMS) and 46 people with possible nocturnal seizures are now monitored by VM. During a 6-month period, in all cases of a suspected seizure we asked the caregivers to specify which device alerted them and to indicate whether this led to an intervention. Staff costs of VM were estimated using payroll information. RESULTS: We identified 1,208 seizures in 37 individuals: 4 had no nocturnal seizures and 393 (33%) seizures were seen only on video. In 169 (14%) of 1,208 seizures an intervention was made and this included 39 (10%) of 393 seizures seen only on video. When compared to seizures observed with an ADS or BMS, seizures seen only on video were more often tonic seizures (71% vs. 22%, p < 0.001) and occurred mostly in the beginning or at the end of the night (40% vs. 26%, p < 0.001). The extra staff costs of monitoring was 7,035 euro per seizure seen only on video and leading to an intervention. SIGNIFICANCE: VM facilitates nocturnal surveillance, but the costs are high. This underscores the need for development of reliable seizure detection devices. PMID- 27686652 TI - Developing immunotherapies for childhood cancer. PMID- 27686653 TI - Available Evidence on Leber Congenital Amaurosis and Gene Therapy. AB - Leber congenital amaurosis (LCA) is a group of severe inherited retinal dystrophies that lead to early childhood blindness. In the last decade, interest in LCA has increased as advances in genetics have been applied to better identify, classify, and treat LCA. To date, 23 LCA genes have been identified. Gene replacement in the RPE65 form of LCA represents a major advance in treatment, although limitations have been recognized. In this article, we review the clinical and genetic features of LCA and evaluate the evidence available for gene therapy in RPE65 disease. PMID- 27686654 TI - Structural Insights into IRE1 Functions in the Unfolded Protein Response. AB - IRE1 signaling is the most evolutionarily conserved branch in the UPR. IRE1 is an ER stress sensor and provides a structure-based platform for the unfolded proteins docking, which causes the luminal domain conformational change and oligomerization. This selfassociation of IRE1 facilitates the phosphorylation of activation loop, which unlocks the autoinhibition in the kinase domain. The activating mechanistic cascade is thus initiated to induce DFG-in conformational change and movement of alphaC-helix to the active site. Structurally, RNase activity is coupled to autophosphorylation and activation of kinase domain. Consequently, the activation of RNase domain in human IRE1 indicates the conformational rearrangement switching the structural arranging pattern from face to-face to back-to-back. IRE1 is still under investigation for target-specific drug development. Two types of ATP-competitive inhibitors of IRE1 kinase are introduced to modify RNase activity, regulating the UPR in response to ER stress. However, once the high activation of RNase surpasses the threshold, its biological roles will switch from adaption to destruction. This might explain for the dual functions of IRE1 in pro-survival and pro-apoptosis. Structural and mechanistic studies of IRE1 highlight the challenge of controlling the UPR in diseases. PMID- 27686655 TI - Anti-cancer Drug Delivery Using Metal Organic Frameworks (MOFs). AB - Cancer is the uncontrolled growth of cells in the body and is considered as one of the major causes of death globally. There are several cytotoxic chemotherapeutic agents used to treat cancer including methotrexate, 5 fluorouracil, cisplatin, tamoxifen, doxorubicin and others. Although billions of dollars have been spent on cancer research to develop these chemotherapies, it still remains a major illness for mankind partly due to the shortcomings of these therapies. These shortcomings include low targeting specificity, severe side effects (due to high doses) and poor pharmacokinetics. To avoid these drawbacks, anti-cancer drug delivery systems have been developed recently using nanocarriers including liposomes, micelles, polyelectrolyte capsules and others. One of the recent class of nanoparticles investigated for chemotherapeutic use are metal organic frameworks (MOFs) which are hybrid polymers that consist of metal ions or clusters and organic ligands. MOFs are used in many applications including gas/vapor separation, gas storage, catalysis, luminescent materials, and biomedical imaging. These structures have additional features that promote their use as drug carriers in the biomedical field. First, they are nontoxic, biodegradable and have the ability to carry high loadings of the anti-neoplastic agent due to their porous nature. Also, they have well-defined crystalline structures that can be characterized by different analytical techniques and their sizes are suitable to control their in vivo drug release. This paper reviews the methods used to synthesize MOFs and their recent use as antineoplastic drug delivery carriers. PMID- 27686656 TI - MDM2 Increases Drug Resistance in Cancer Cells by Inducing EMT Independent of p53. AB - Mdm2 is a well studied oncogene and has been reported to be closely related to chemoresistance in different manners. In this article, we discuss the current knowledge of mdm2's function in drug resistance, the novel relationship between MDM2 and Akt phosphorylation, the role of Akt signaling pathway in epithelial mesenchymal transition, and the positive correlation among MDM2, epithelial mesenchymal transition and drug resistance. We propose a possible pathway by which MDM2 increases drug resistance through inducing epithelial-mesenchymal transition independent of p53. This pathway may play a significant role in the tumorigenesis and chemoresistance. By targeting MDM2, we can re-activate the function of p53, inhibit the epithelial-mesenchymal transition process and thus increase cancer cells sensitivity to chemotherapy. Thus, from p53-dependent and p53-independent aspects, it may present a better strategy for cancer treatment than targeting other genes. PMID- 27686657 TI - Overview of Systems Biology and Omics Technologies. AB - Traditional technologies using reductionist approach are relatively insufficient to solve problems in a biological system. Rather than a reductionist approach, systems biology uses a holistic and integrative approach to better figure out the whole process. Both qualitatively and quantitatively of biological system provide information about diseases, toxicities, therapies etc. Omics technologies, which systems biology brings, are valuable tools for comprehensive analyses. Automated DNA sequencers enabled the sequencing of genomes; microarray and mass spectrometry analysis permit global transcriptional profiling and lead to large scale proteomic and metabolomics analysis. These high-throughput data need to be interpreted by bioinformatics. So far there has been no concrete published paper that compiles omics technologies according to PubMed database. In the present review, it was aimed to give brief description of systems biology and information on the advantages and disadvantages of omics technologies. PMID- 27686658 TI - Alterations in Cerebral Cortical Glucose and Glutamine Metabolism Precedes Amyloid Plaques in the APPswe/PSEN1dE9 Mouse Model of Alzheimer's Disease. AB - Alterations in brain energy metabolism have been suggested to be of fundamental importance for the development of Alzheimer's disease (AD). However, specific changes in brain energetics in the early stages of AD are poorly known. The aim of this study was to investigate cerebral energy metabolism in the APPswe/PSEN1dE9 mouse prior to amyloid plaque formation. Acutely isolated cerebral cortical and hippocampal slices of 3-month-old APPswe/PSEN1dE9 and wild type control mice were incubated in media containing [U-13C]glucose, [1,2 13C]acetate or [U-13C]glutamine, and tissue extracts were analyzed by mass spectrometry. The ATP synthesis rate of isolated whole-brain mitochondria was assessed by an on-line luciferin-luciferase assay. Significantly increased 13C labeling of intracellular lactate and alanine and decreased tricarboxylic acid (TCA) cycle activity were observed from cerebral cortical slices of APPswe/PSEN1dE9 mice incubated in media containing [U-13C]glucose. No changes in glial [1,2-13C]acetate metabolism were observed. Cerebral cortical slices from APPswe/PSEN1dE9 mice exhibited a reduced capacity for uptake and oxidative metabolism of glutamine. Furthermore, the ATP synthesis rate tended to be decreased in isolated whole-brain mitochondria of APPswe/PSEN1dE9 mice. Thus, several cerebral metabolic changes are evident in the APPswe/PSEN1dE9 mouse prior to amyloid plaque deposition, including altered glucose metabolism, hampered glutamine processing and mitochondrial dysfunctions. PMID- 27686659 TI - Increased Expression of Slit2 and its Robo Receptors During Astroglial Scar Formation After Transient Focal Cerebral Ischemia in Rats. AB - Slit2, a secreted glycoprotein, has recently been implicated in the post-ischemic astroglial reaction. The objective of this study was to investigate the temporal changes and cellular localization of Slit2 and its receptors, Robo1, Robo2, and Robo4, in a rat transient focal ischemia model induced by middle cerebral artery occlusion. We used double- and triple-immunolabeling to determine the cell specific changes in Slit2 and its receptors during a 10-week post-ischemia period. The expression profiles of Slit2 and the Robo receptors shared overlapping expression patterns in sham-operated and ischemic striatum. Constitutive expression of Slit2 and Robo receptors was observed in striatal neurons with weak intensity, whereas in rats reperfused after ischemic insults, these immunoreactivities were increased in reactive astrocytes. Astroglial induction of Slit2 and Robo in the peri-infarct region was distinct on days 7-14 after reperfusion and thereafter increased progressively throughout the 10-week experimental period. Slit2 and Robo were prominently expressed in the perinuclear cytoplasm and main processes of reactive astrocytes forming the astroglial scar. This observation was confirmed by quantification of the mean fluorescence intensity of Slit2 and Robo receptors over reactive astrocytes localized at the edge of the infarct area. However, activated microglia/macrophages in the peri infarct area were devoid of any specific labeling for Slit2 and Robo. Thus, our data revealed a selective and sustained induction of Slit2 and Robo in astrocytes localized throughout the astroglial scar after ischemic stroke, suggesting that Slit2/Robo signaling participates in glial scar formation and brain remodeling following ischemic injury. PMID- 27686660 TI - Neuroprotective Effects of Theaflavins Against Oxidative Stress-Induced Apoptosis in PC12 Cells. AB - Oxidative stress can induce neuronal apoptosis via the production of superoxide and hydroxyl radicals. This process is as a major pathogenic mechanism in neurodegenerative disorders. In this study, we aimed to clarify whether theaflavins protect PC12 cells from oxidative stress damage induced by H2O2. A cell model of PC12 cells undergoing oxidative stress was created by exposing cells to 200 MUM H2O2 in the presence or absence of varying concentrations of theaflavins (5, 10, and 20 MUM). Cell viability was monitored using the MTT assay and Hoechst 33258 staining, showing that 10 MUM theaflavins enhanced cell survival following 200 MUM H2O2 induced toxicity and increased cell viability by approximately 40 %. Additionally, we measured levels of intracellular reactive oxygen species (ROS) and antioxidant enzyme activity. This suggested that the neuroprotective effect of theaflavins against oxidative stress in PC12 cells is derived from suppression of oxidant enzyme activity. Furthermore, Western blot analyses indicated that theaflavins downregulated the ratio of pro-apoptosis/anti apoptosis proteins Bax/Bcl-2. Theaflavins also downregulated the expression of caspase-3 compared with a H2O2-treated group that had not been treated with theaflavins. Interestingly, this is the first study to report that the four main components of theaflavins found in black tea can protect neural cells (PC12) from apoptosis induced by H2O2. These findings provide the foundations for a new field of using theaflavins or its source, black tea, in the treatment of neurodegenerative diseases caused by oxidative stress. PMID- 27686661 TI - Lidocaine controls pain and allows safe wound bed preparation and debridement of digital ulcers in systemic sclerosis: a retrospective study. AB - In Systemic Sclerosis (SSc), digital ulcers (DU) are painful, difficult to heal, and frequently infected. To reduce the risk of bacterial infection and to prevent chronicity, it is essential to carefully remove necrotic tissue from DU, with maximum patient comfort. Debridement, although very efficacious, is invasive and causes local pain: lidocaine is a local anesthetic commonly used as to fight pain during debridement procedures. The aim of the study was to evaluate the efficacy of lidocaine 4 % in pain control during debridement procedure of DU in SSc. One hundred eight DU characterized by pain Numeric Rating Scale (NRS) >3/10 before starting the procedure were treated with lidocaine 4 % (lidocaine cloridrate 200 mg in 5 ml of injecting solution). Pain was measured with NRS (0-10) before starting debridement, after 15 min of lidocaine application and at the end of the procedure. In DU, in respect to baseline (mean NRS 6.74 +/- 2.96), pain after application of lidocaine 4 % for 15 min was significantly lower (mean NRS 2.83 +/ 2.73) (p < 0.001). At the end of the procedure, pain control was still maintained and significantly lower (mean NRS 2.88 +/- 2.65) in respect to baseline (p < 0.001). No systemic adverse event due to topical lidocaine were observed. In SSc, topical application of lidocaine 4 % significantly reduces pain, allowing a safe debridement procedure, thus improving the management of DU. PMID- 27686663 TI - Effects of Mydrin eye-drops on central corneal thickness values in adult patients with myopia. AB - OBJECTIVE: This study aimed to evaluate the effect of Mydrin eye-drops on central corneal thickness values and investigate the duration of the effect. METHODS: In this prospective randomised self-controlled study, we enrolled 60 myopic patients (120 eyes) undergoing corneal laser refractive surgery. The central corneal thickness was measured before and one and four hours after administration of Mydrin eye-drops (major components are tropicamide and phenylephrine hydrochloride) using the Orbscan II anterior segment analysis system and a SP 2000P non-contact specular microscope, respectively. RESULTS: Using the Orbscan II system, the baseline central corneal thickness (545 +/- 27 um) was significantly lower than that at one hour after Mydrin eye-drop application (559 +/- 31 um; p < 0.001); it was comparable to that at four hours post-Mydrin eye drop administration (544 +/- 26 um; p < 0.74). Measured by non-contact specular microscopy, the baseline central corneal thickness (508 +/- 26 um) was significantly lower than that at one hour after Mydrin eye-drop application (521 +/- 29 um; p < 0.001); it was comparable to that at four hours after Mydrin eye drop administration (506 +/- 24 um; p = 0.62). A significant difference was observed in the central corneal thickness at one and four hours after Mydrin eye drop application by both methods (p < 0.001). Bland-Altman plots showed agreement between the measurements by the two methods at different times. CONCLUSION: Central corneal thickness increases one hour after topical application of Mydrin eye-drops and is normalised at four hours following the administration of the drops. For patients scheduled to undergo excimer laser corneal refractive surgery, the central corneal thickness should be measured before or four hours after administration of Mydrin eye-drops. PMID- 27686662 TI - Different roles of TNF inhibitors in acute anterior uveitis associated with ankylosing spondylitis: state of the art. AB - The purpose of the present review was to provide a comprehensive picture of the efficacy of the different tumor necrosis factor (TNF)-alpha inhibiting agents in the treatment of acute anterior uveitis (AAU), the most common extra-articular manifestation of ankylosing spondylitis (AS). AS related, AAU may lead to severe visual impairment, due to frequent flare recurrences, anterior, and posterior segment complications and traditional treatment side effects. Considerably higher levels of tumor necrosis factor (TNF) have been assessed in the aqueous humor and inflamed joints of patients with AS. Anti-TNF drugs have shown efficacy in preventing relapses of rheumatological manifestations of spondyloarthropathies. Several studies have underlined the sustained efficacy of the monoclonal anti-TNF antibodies also in reducing the recurrence of anterior chamber flares in patients with AS-related AAU. On the other hand, retrospective studies and observational reports have indicated lower effectiveness and some paradoxical occurrence of uveitis following treatment with the soluble receptor agent etanercept. Growing evidence suggests that a prophylactic strategy could be advocated in subjects with frequent and recalcitrant attacks of AS-AAU. In this regard, the administration of monoclonal anti-TNF antibodies such as adalimumab (ADA) has been shown to significantly reduce the rate of AAU recurrences. Indeed, during ADA treatment about 90 % of patients have shown to remain completely free of attacks for the entire follow-up period, in most studies. Further studies are needed to confirm the long-term efficacy of TNF inhibitors in AS related AAU and also their role in preventing ocular complications and visual impairment. PMID- 27686664 TI - Investigation of a type C/D botulism outbreak in free-range laying hens in France. AB - In 2014, a botulism outbreak in a flock of laying hens was investigated in France. In the flock of 5020 hens, clinical signs of botulism occurred at 46 weeks of age. A type C/D botulism outbreak was confirmed using the mouse lethality assay for detection of botulinum toxin in serum and a real-time PCR test to detect Clostridium botulinum in intestinal contents. The disease lasted one week with a mortality rate of 2.6% without recurrence. Botulism in laying hens has rarely been reported. Five monthly visits were made to the farm between December 2014 and May 2015 for a longitudinal study of the persistence of C. botulinum in the poultry house after the outbreak, and to assess egg contamination by C. botulinum. Several samples were collected on each visit: in the house (from the ventilation circuit, the egg circuit, water and feed, droppings) and the surrounding area. Thirty clean and 30 dirty eggs were also swabbed at each visit. In addition, 12 dirty and 12 clean eggs were collected to analyse eggshell and egg content. The samples were analysed using real-time PCR to detect type C/D C. botulinum. The bacterium was still detected in the house more than 5 months after the outbreak, mostly on the walls and in the egg circuit. Regarding egg contamination, the bacteria were detected only on the shell but not in the content of the eggs. Control measures should therefore be implemented throughout the egg production period to avoid dissemination of the bacteria, particularly during egg collection. PMID- 27686665 TI - Antiinflammatory Effects of Functionally Active Compounds Isolated from Aged Black Garlic. AB - The antiinflammatory effects of functionally active compounds isolated from aged black garlic (AGE-1 and AGE-2) were investigated using a lipopolysaccharide induced inflammatory response model. To examine the potential antiinflammatory properties of AGE-1 and AGE-2, cell viability as well as nitric oxide, prostaglandin E2, and pro-inflammatory cytokine [interleukin-6 (IL-6), TNF-alpha, and IL-1beta] levels were measured. The mRNA and protein expression levels of inducible nitric oxide synthase and cyclooxygenase-2 were detected by reverse transcription polymerase chain reaction and western blotting. The results indicated that AGE-1 and AGE-2 were not cytotoxic to macrophages. Nitric oxide and prostaglandin E2 levels decreased significantly with increasing concentration of AGE-1 (IC50 = 29.6 and 1.41 ug/mL, respectively), but not AGE-2. The secretion of IL-6, TNF-alpha, and IL-1beta was also suppressed by AGE-1 in a dose dependent manner, and inducible nitric oxide synthase and cyclooxygenase-2 mRNA, and protein expression decreased with AGE-1 treatment. Furthermore, AGE-1 attenuated the phosphorylation of the extracellular signal-regulated kinase, p38, and c-Jun terminal kinase in lipopolysaccharide-induced RAW264.7 cells. These results suggested that compound AGE-1 may have significant effects on inflammatory factors and could potentially be used as an antiinflammatory therapeutic agent.

PMID- 27686666 TI - Pathological complete response after neoadjuvant chemotherapy for rectal cancer with synchronous multiple liver metastases: a report of an unusual case. AB - BACKGROUND: Systemic chemotherapy for stage IV colorectal cancer has advanced markedly in the recent years. We report an unusual case of 13 synchronous liver metastases for which a pathological complete response was achieved with neoadjuvant chemotherapy (NAC) consisting of a combination of 5-fluorouracil (5 FU), oxaliplatin, leucovorin (mFOLFOX6), and bevacizumab. CASE PRESENTATION: A 44 year-old man was diagnosed with colorectal cancer with synchronous liver metastases. We resected the primary rectal tumor first. Further, after providing NAC for hepatic metastases, lateral segmentectomy and partial resection of the liver were performed. The subsequent result was compatible with a complete pathological response. The postoperative course was uneventful, and the patient is currently alive 5 years after the first surgery without evidence of recurrence and without adjuvant chemotherapy. CONCLUSIONS: For patients with initially resectable colorectal liver metastases, the survival benefits of NAC are still unclear. We report a rare case of 13 synchronous liver metastatic lesions from rectal cancer with a complete pathological response after neoadjuvant bevacizumab containing chemotherapy.

AB - We assessed the functional properties in atrial and ventricular myocardium (using isolated cardiac strips) of smooth dogfish (Mustelus canis), clearnose skate (Raja eglanteria), and sandbar shark (Carcharhinus plumbeus) by blocking Ca2+ release from the sarcoplasmic reticulum (SR) with ryanodine and thapsigargin and measuring the resultant changes in contraction-relaxation parameters and the force-frequency relationship at 20 degrees C and 30 degrees C. We also examined ultrastructural differences with electron microscopy. In tissues from smooth dogfish, net force (per cross-sectional area) and measures of the speeds of contraction and relaxation were all higher in atrial than ventricular myocardium at both temperatures. Atrial-ventricular differences were evident in the other two species primarily in measures of the rates of contraction and relaxation. Ryanodine-thapsigargin treatment reduced net force and its maximum positive first derivative (i.e., contractility), and increased time to 50 % relaxation in atrial tissue from smooth dogfish at 30 degrees C. It also increased times to peak force and half relaxation in clearnose skate atrial and ventricular tissue at both temperatures, but only in atrial tissue from sandbar shark at 30 degrees C; indicating that SR involvement in excitation-contraction (EC) coupling is species and temperature-specific in elasmobranch fishes, as it is in teleost fishes. Atrial and ventricular myocardium from all three species displayed a negative force-frequency relationship, but there was no evidence that SR involvement in EC coupling was influenced by heart rate. SR was evident in electron micrographs, generally located in proximity to mitochondria and intercalated discs, and to a lesser extent between the myofibrils; with mitochondria being more numerous in ventricular than atrial myocardium in all three species.

AB - Marine mammals are characterized as having physiological specializations that maximize the use of oxygen stores to prolong time spent under water. However, it has been difficult to undertake the requisite controlled studies to determine the physiological limitations and trade-offs that marine mammals face while diving in the wild under varying environmental and nutritional conditions. For the past decade, Steller sea lions (Eumetopias jubatus) trained to swim and dive in the open ocean away from the physical confines of pools participated in studies that investigated the interactions between diving behaviour, energetic costs, physiological constraints, and prey availability. Many of these studies measured the cost of diving to understand how it varies with behaviour and environmental and physiological conditions. Collectively, these studies show that the type of diving (dive bouts or single dives), the level of underwater activity, the depth and duration of dives, and the nutritional status and physical condition of the animal affect the cost of diving and foraging. They show that dive depth, dive and surface duration, and the type of dive result in physiological adjustments (heart rate, gas exchange) that may be independent of energy expenditure. They also demonstrate that changes in prey abundance and nutritional status cause sea lions to alter the balance between time spent at the surface acquiring oxygen (and offloading CO2 and other metabolic by-products) and time spent at depth acquiring prey. These new insights into the physiological basis of diving behaviour further our understanding of the potential scope for behavioural responses of marine mammals to environmental changes, the energetic significance of these adjustments, and the consequences of approaching physiological limits. PMID- 27686670 TI - Clients' perspective on quality of audiology care: Development of the Consumer Quality Index (CQI) 'Audiology Care' for measuring client experiences. AB - OBJECTIVE: Clients' perspective on the quality of audiology care has not been investigated thoroughly. Research has focused primarily on satisfaction with, and limitations of hearing aids. We developed a Consumer Quality Index (CQI) questionnaire 'Audiology Care' to systematically assess client experiences with audiology care. DESIGN: The CQI Audiology Care was developed in three steps: (1) posing open-ended questions through e-mail (n = 14), (2) two small-scale surveys assessing psychometric properties of the questionnaire (n = 188) and importance of quality aspects (n = 118), and (3) a large-scale survey (n = 1793) assessing psychometric properties and discriminatory power of the questionnaire. STUDY SAMPLE: People with complex hearing impairments and/or balance and communicative disorders who visited an audiology care centre during the past year. RESULTS: Important quality aspects were translated into seven reliable scales: accommodation and facilities, employees' conduct and expertise, arrangement of appointments, waiting times, client participation and effectiveness of treatment. Client experiences differed among the participating centres concerning accommodation and facilities, arrangement of appointments, waiting times and client participation. CONCLUSION: The CQI Audiology Care is a valid and reliable instrument to assess clients' experiences with audiology care. Future implementation will reveal whether results can be used to monitor and improve the quality of audiology care.

AB - Large granular lymphocyte leukemia (LGL-L) is defined morphologically as a group of lymphoproliferative disorders, including T-cell large granular lymphocytic leukemia (T-LGL-L), chronic lymphoproliferative disorders of NK cells (CLPD-NK), and aggressive NK cell leukemia. We investigated the morphological features of LGL leukemic cells in LGL-L patients to identify screening methods best suited to application in daily clinical practice. LGL leukemic cells were mostly indistinguishable from normal LGL; however, we developed a simplified approach to distinguishing among these cells, in which lymphocyte % and the proportion of granular lymphocytes among lymphocytes (GL %) can serve as parameters at the cut off values of 52 and 50 %, respectively. We confirmed the accuracy of these methods in validation groups. It may be useful to evaluate GL % to screen for LGL L using a cut-off threshold of 50 when Lym % exceeds 52 in the peripheral blood examination in cases in which LGL-L is suspected in daily practice while keeping clinical context and the coefficient of variation of these parameters under consideration. PMID- 27686671 TI - Structural basis of steroid binding and oxidation by the cytochrome P450 CYP109E1 from Bacillus megaterium. AB - : Cytochrome P450 monooxygenases (P450s) are attractive enzymes for the pharmaceutical industry, in particular, for applications in steroidal drug synthesis. Here, we report a comprehensive functional and structural characterization of CYP109E1, a novel steroid-converting cytochrome P450 enzyme identified from the genome of Bacillus megaterium DSM319. In vitro and whole-cell in vivo turnover experiments, combined with binding assays, revealed that CYP109E1 is able to hydroxylate testosterone at position 16beta. Related steroids with bulky substituents at carbon C17, like corticosterone, bind to the enzyme without being converted. High-resolution X-ray structures were solved of a steroid-free form of CYP109E1 and of complexes with testosterone and corticosterone. The structural analysis revealed a highly dynamic active site at the distal side of the heme, which is wide open in the absence of steroids, can bind four ordered corticosterone molecules simultaneously, and undergoes substantial narrowing upon binding of single steroid molecules. In the crystal structures, the single bound steroids adopt unproductive binding modes coordinating the heme-iron with their C3-keto oxygen. Molecular dynamics (MD) simulations suggest that the steroids may also bind in ~180 degrees reversed orientations with the C16 carbon and C17-substituents pointing toward the heme, leading to productive binding of testosterone explaining the observed regio- and stereoselectivity. The X-ray structures and MD simulations further identify several residues with important roles in steroid binding and conversion, which could be confirmed by site-directed mutagenesis. Taken together, our results provide unique insights into the CYP109E1 activity, substrate specificity, and regio/stereoselectivity. DATABASE: The atomic coordinates and structure factors have been deposited in the Protein Data Bank with accession codes 5L90 (steroid free CYP109E1), 5L91 (CYP109E1-COR4), 5L94 (CYP109E1-TES), and 5L92 (CYP109E1 COR).

PMID- 27686673 TI - Comparison of cyclosporine and tacrolimus combined with mycophenolate mofetil in prophylaxis for graft-versus-host disease after reduced-intensity umbilical cord blood transplantation. AB - Umbilical cord blood transplantation with a reduced-intensity conditioning regimen (RIC-UCBT) is used increasingly in patients who have comorbid organ functions and lack human leukocyte antigen-identical donors. We compared the outcomes in 35 patients who received mycophenolate mofetil plus cyclosporine (MMF/CSP, n = 17) or MMF plus tacrolimus (MMF/TAC, n = 18) for graft-versus-host disease (GVHD) prophylaxis after RIC-UCBT. Cumulative incidence of neutrophil engraftment was 94 and 89 % in MMF/CSP and MMF/TAC groups, respectively (p = 0.34). The incidence of pre-engraftment immune reaction did not differ between the MMF/CSP (41 %) and MMF/TAC (39 %, p = 1.00) groups; however, patients in the MMF/TAC group tended to have a lower incidence of grade II-IV acute GVHD than those in MMF/CSP group (28 vs 53 %, p = 0.11). Overall survival (OS) at 1 year was 43 and 60 % in MMF/CSP and MMF/TAC groups, respectively (p = 0.39). Progression-free survival, non-relapse mortality, and relapse rate were comparable between the two groups (p = 0.76, 0.59, and 0.88, respectively). In multivariate analyses, MMF/TAC GVHD prophylaxis was closely associated with improved OS, but not with incidence of engraftment and acute GVHD. These results suggest that more intensive GVHD prophylaxis with MMF/TAC decreased acute GVHD without affecting other clinical outcomes, resulting in improved OS after RIC UCBT. PMID- 27686674 TI - Constitutional t(8;22)(q24;q11.2) that mimics the variant Burkitt-type translocation in Philadelphia chromosome-positive chronic myeloid leukemia. AB - Constitutional translocations that coincide with t(9;22)(q34;q11.2) may lead to unnecessary treatments in chronic myeloid leukemia (CML) patients, as, under the standard criteria, a diagnosis of CML with additional chromosomal abnormalities indicates an accelerated phase (AP). In the present report, a 47-year-old male had pain in the right foot due to gout. Peripheral blood examination showed leukocytosis with left shift. Bone marrow aspiration revealed myeloid hyperplasia with megakaryocytosis. RT-PCR revealed the major BCR-ABL fusion transcript, and CML in the chronic phase was diagnosed, followed by nilotinib treatment. Although WBC counts decreased immediately, G-banding analysis showed 46,XY,t(8;22)(q24;q11.2),t(9;22)(q34;q11.2) [20]. The t(8;22)(q24;q11.2) translocation is known to be recurrent in Burkitt's lymphoma. The diagnosis was changed to CML in AP, leading to B-lymphoid crisis. Unexpectedly, the karyotype was 46,XY,t(8;22)(q24;q11.2) [20] in hematological complete remission, even after 3 months. Fluorescence in situ hybridization on metaphase spreads revealed the MYC signal on the der(22)t(8;22), indicating that the 8q24 breakpoint was centromeric to MYC at 8q24.21. G-banding analysis of phytohemagglutinin stimulated peripheral blood T-lymphocytes also indicated 46,XY,t(8;22)(q24.1;q11.2). We conclude that the t(8;22) is constitutional in this patient. As the tumor suppressor gene TRC8/RNF139 is disrupted by constitutional t(8;22)(q24.13;q11.21) in dysgerminoma, it may be associated with the onset of CML. PMID- 27686676 TI - Central Nervous System Device Infections. AB - Nosocomial meningitis can occur in association with central nervous system (CNS) devices such as cerebrospinal shunts or drains, intrathecal pumps, and deep brain stimulators and carry substantial morbidity and mortality. Diagnosing and treating these infections may be challenging to physicians as cerebrospinal fluid cultures may be negative due to previous antibiotic therapy and cerebrospinal abnormalities may be secondary to the primary neurosurgical issue that prompted the placement of the CNS device (e.g., "chemical meningitis" due to intracranial hemorrhage). Besides antibiotic therapy given intravenously and sometimes intrathecally, removal of the device with repeat cultures prior to re implantation is key in achieving successful outcomes. PMID- 27686675 TI - Progressive Multifocal Leukoencephalopathy in HIV-Uninfected Individuals. AB - Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system (CNS) caused by the human neurotropic polyomavirus JC (JCV). The disease occurs virtually exclusively in immunocompromised individuals, and, prior to the introduction of antiretroviral therapy, was seen most commonly in the setting of HIV/AIDS. More recently, however, the incidence of PML in HIV uninfected persons has increased with broader use of immunosuppressive and immunomodulatory medications utilized in a variety of systemic and neurologic autoimmune disorders. In this review, we discuss the epidemiology and clinical characteristics of PML in HIV-uninfected individuals, as well as diagnostic modalities and the limited treatment options. Moreover, we describe recent findings regarding the neuropathogenesis of PML, with specific focus on the unique association between PML and natalizumab, a monoclonal antibody that prevents trafficking of activated leukocytes into the CNS that is used for the treatment of multiple sclerosis.

PMID- 27686677 TI - Laboratory Diagnosis of Central Nervous System Infection. AB - Central nervous system (CNS) infections are potentially life threatening if not diagnosed and treated early. The initial clinical presentations of many CNS infections are non-specific, making a definitive etiologic diagnosis challenging. Nucleic acid in vitro amplification-based molecular methods are increasingly being applied for routine microbial detection. These methods are a vast improvement over conventional techniques with the advantage of rapid turnaround and higher sensitivity and specificity. Additionally, molecular methods performed on cerebrospinal fluid samples are considered the new gold standard for diagnosis of CNS infection caused by pathogens, which are otherwise difficult to detect. Commercial diagnostic platforms offer various monoplex and multiplex PCR assays for convenient testing of targets that cause similar clinical illness. Pan-omic molecular platforms possess potential for use in this area. Although molecular methods are predicted to be widely used in diagnosing and monitoring CNS infections, results generated by these methods need to be carefully interpreted in combination with clinical findings. This review summarizes the currently available armamentarium of molecular assays for diagnosis of central nervous system infections, their application, and future approaches. PMID- 27686679 TI - Epithelial-mesenchymal transition in cholangiocarcinoma: From clinical evidence to regulatory networks. AB - Cholangiocarcinoma (CCA) is an aggressive tumor with a poor prognosis due to its late clinical presentation and the lack of effective non-surgical therapies. Unfortunately, most of the patients are not eligible for curative surgery owing to the presence of metastases at the time of diagnosis. Therefore, it is important to understand the steps leading to cell dissemination in patients with CCA. To metastasize from the primary site, cancer cells must acquire migratory and invasive properties by a cell plasticity-promoting phenomenon known as epithelial-mesenchymal transition (EMT). EMT is a reversible dynamic process by which epithelial cells gradually adopt structural and functional characteristics of mesenchymal cells, and has lately become a centre of attention in the field of metastatic dissemination. In the present review, we aim to provide an extensive overview of the current clinical data and the prognostic value of different EMT markers that have been analysed in CCA. We summarize all the regulatory networks implicated in EMT from the membrane receptors to the main EMT-inducing transcription factors (SNAIL, TWIST and ZEB). Furthermore, since a tumor is a complex structure not exclusively formed by tumor cells, we also address the prominent role of the main cell types of the desmoplastic stroma that characterizes CCA in the regulation of EMT. Finally, we discuss the therapeutic considerations and difficulties faced to develop an effective anti-EMT treatment due to the redundancies and bypasses among the pathways regulating EMT. PMID- 27686680 TI - Effect of ventriculo-arterial coupling on transplant outcomes in cirrhotics: Analysis of pressure-volume curve relations. AB - BACKGROUND & AIMS: Ventriculo-arterial coupling (VAC) reflects the interaction between ventricular performance and effective arterial load. Current criteria for cirrhotic cardiomyopathy focus only on cardiac function without addressing the effect of hyperdynamic, low-resistance circulation. We investigated alterations in VAC in cirrhotic patients and their associations with post-liver transplant all-cause mortality. METHODS: In this single institution cohort study, cirrhotic patients who underwent liver transplantation (LT) (n=914) were retrospectively compared with healthy matched controls using noninvasively measured end-systolic ventricular elastance (Ees), arterial elastance (Ea), and VAC (Ea/Ees). All-cause mortality based on VAC values were investigated using a Cox hazard model with the inverse probability treatment weighting (IPTW) of propensity score. RESULTS: Cirrhotic patients had significantly lower Ees, Ea and VAC values than controls. Over a median of 30months, 96 patients died after LT. In patients with a high model for end-stage liver disease score (?25), VAC of >0.61 (highest tertile) had poorer survival outcomes than patients with VAC of ?0.50 (lowest tertile) (66.0% vs. 91.8%; Log-rank p=0.001), and was independently associated with risk of mortality (hazard ratio, 2.44; 95% CI, 1.10-5.39; p=0.028) compared with VAC of ?0.61 after IPTW adjustment. CONCLUSIONS: In cirrhotic patients, ventricular elastance and VAC values are lower than those in controls. However, in advanced cirrhotic patients, an increase in VAC value is associated with all-cause mortality after LT, suggesting that this non-invasive estimation of ventriculo arterial uncoupling is an additional novel prognosticator in cirrhotic cardiovascular disorders. LAY SUMMARY: In cirrhotic patients, cardiac dysfunction is latent and only manifests under stressful conditions because of arterial vasodilation. In this study, based on the pressure-volume curve of cardiac function, we investigated characteristics of the ventricular-arterial coupling in cirrhotic patients and further found that disparities in the ventriculo-arterial relationship are associated with graft failure and all-cause mortality after liver transplantation. PMID- 27686681 TI - Mimicking the Impact of Infant Tongue Peristalsis on Behavior of Solid Oral Dosage Forms Administered During Breastfeeding. AB - An in vitro simulation system was developed to study the effect of an infant's peristaltic tongue motion during breastfeeding on oral rapidly disintegrating tablets in the mouth, for use in rapid product candidate screening. These tablets are being designed for use inside a modified nipple shield worn by a mother during breastfeeding, a proposed novel platform technology to administer drugs and nutrients to breastfeeding infants. In this study, the release of a model compound, sulforhodamine B, from tablet formulations was studied under physiologically relevant forces induced by compression and rotation of a tongue mimic. The release profiles of the sulforhodamine B in flowing deionized water were found to be statistically different using 2-way ANOVA with matching, when tongue mimic rotation was introduced for 2 compression levels representing 2 tongue strengths (p = 0.0013 and p < 0.0001 for the lower and higher compression settings, respectively). Compression level was found to be a significant factor for increasing model compound release at rotational rates representing nonnutritive breastfeeding (p = 0.0162). This novel apparatus is the first to simulate the motion and pressures applied by the tongue and could be used in future infant oral product development. PMID- 27686682 TI - Note on the Use of Diametrical Compression to Determine Tablet Tensile Strength. AB - The diametrical compression (DC) test, as defined in United States Pharmacopeia <1217> and in American Society for Testing and Materials testing standard D 3967, has been used extensively to derive the tensile strength (TS) of pharmaceutical tablets from the measured breaking force. DC-derived TSs provide a good approach to measuring the consistency of tablet mechanical properties from one batch to the next. For these quality control type applications, method precision is required, but accuracy is not. In addition, DC has been used to calibrate parameters of the Druker Prager Cap model, a yield criterion expressing the failure of a powder compact under arbitrary 3D loading conditions. For this application, the DC method must not only provide suitable precision but also provide accuracy. In this work, we explore the accuracy of the DC method by comparing TS results to those of the 3-point bend test method (also defined in United States Pharmacopeia <1217>). We conclude that the true TS of a powder compact is approximately double the DC-derived value. Although historical literature assumes that tablets fracture under tension along the centerline of the tablet, analysis of the stress state suggests that tablets are likely to fracture under shear. The impact of this ~50% error should be considered when accuracy of the TS result is required. PMID- 27686683 TI - Assessment of Tablet Surface Hardness by Laser Ablation and Its Correlation With the Erosion Tendency of Core Tablets. AB - Surface erosion of uncoated tablets results in processing problems such as dusting and defects during coating and is governed by the strength of particle bonding on tablet surface. In this study, the correlation between dusting tendency of tablets in a coating pan with friability and laser ablation surface hardness was assessed using tablets containing different concentrations of magnesium stearate and tartaric acid. Surface erosion propensity of different batches was evaluated by assessing their dusting tendency in the coating pan. In addition, all tablets were analyzed for crushing strength, friability, modified friability test using baffles in the friability apparatus, and weight loss after laser ablation. Tablets with similar crushing strength showed differences in their surface erosion and dusting tendency when rotated in a coating pan. These differences did not correlate well with tablet crushing strength or friability but did show reasonably good correlation with mass loss after laser ablation. These results suggest that tablet surface mass loss by laser ablation can be used as a minipiloting (small-scale) tool to assess tablet surface properties during early stages of drug product development to assess the risk of potential large scale manufacturing issues.

PMID- 27686684 TI - A case report of unusually long lag time between immunotactoid glomerulopathy (itg) diagnosis and diffuse large B-cell lymphoma (DLBCL) development. AB - BACKGROUND: Immunotactoid glomerulopathy (ITG) is a rare cause of proteinuria characterized by organized microtubular deposits in the glomerulus. ITG has been associated with underlying lymphoproliferative disorders and any renal impairment may be reversible with treatment of the concomitant hematologic malignancy. This case is the first reported in literature where diffuse large B cell lymphoma developed two years following the initial ITG diagnosis. CASE PRESENTATION: A 55 year-old woman with a history of well-controlled diabetes mellitus and thalassemia trait presented with proteinuria (830 mg/day) in 2010. Initially, she was managed with renin-angiotensin-aldosterone-system blockade. In 2012, the proteinuria worsened (4.3 g/day) and a renal biopsy showed immunotactoid glomerulopathy (Fig. 1). Despite extensive work up, no lymphoproliferative disorder was initially found. In January 2014, the patient presented with a soft palate mass found on biopsy to be diffuse large B-cell lymphoma. She received 6 cycles of R-CHOP, 4 cycles of high dose methotrexate chemotherapy for CNS prophylaxis and 30 Gy of Intensity Modulated Radiation Therapy. Follow-up revealed complete remission of diffuse large B-cell lymphoma and resolution of proteinuria from the ITG. CONCLUSION: As we recognize that patients with ITG may develop hematopoietic neoplasms, close long-term monitoring is important. Moreover, treatment of the lymphoproliferative disorder can allow for complete remission of ITG. PMID- 27686687 TI - Spectral characteristics of intracranial electroencephalographic activity in patients with Lennox-Gastaut syndrome. AB - OBJECTIVE: The purpose of the current study was to characterize the frequency profiles of epileptogenic regions, independent of visible epileptiform discharges, in intracranial EEG (iEEG) recordings of Lennox-Gastaut syndrome (LGS) patients. METHODS: We selected eight LGS patients who underwent resective surgery in the absence of definite neuroimaging findings. We calculated the absolute and relative band powers of continuous spike-free iEEG data and compared the characteristics of the resected and remaining regions. RESULTS: For absolute band powers, there was a trend for higher absolute gamma band power in the remaining brain section. We also found that the absolute delta power in the resected area was higher than that in the remaining area. However, this trend was not statistically different in all patients. For relative band powers, we found decreased relative band power in the beta and gamma band ranges within the areas defined by the surgical margins. Delta, theta, and alpha relative band power differences between the resected and remaining areas were inconsistent between the subjects. CONCLUSIONS: Our results showed systematic relative beta and gamma band power variation in the resected areas of LGS patients. PMID- 27686688 TI - A pediatric patient of hemorrhagic acute transverse myelitis. AB - An 11-year-old boy presented with progressive leg hypesthesia but no history of trauma. Dysuria and constipation appeared subsequent to gait difficulty. He was admitted 8days after onset. Spinal magnetic resonance imaging (MRI) revealed longitudinal hyperintensity with cord swelling and hypointensity on T2-weighted images, suggesting severe inflammation and microbleeding change, respectively. Gadolinium contrast-enhanced MRI demonstrated mild enhancement in the lesions. Platelet count and coagulation findings were normal, and cerebrospinal fluid analysis showed no pleocytosis. He was diagnosed with idiopathic acute transverse myelitis (ATM), and intravenous methylprednisolone pulse therapy and plasmapheresis were initiated. On day 14, motor dysfunction aggravated suddenly, accompanied by expanding hemorrhagic lesions. Thereafter, administration of intravenous immunoglobulin, repeated intravenous methylprednisolone pulse therapy and prednisolone for one month resulted in complete recovery four months later. Both anti-aquaporin-4 and anti-myelin oligodendrocyte glycoprotein antibodies were negative. We presented the first pediatric case showing hemorrhagic spinal lesions in the clinical course of ATM. This severe complication should be recognized in the management of ATM. PMID- 27686689 TI - An Evaluation of Treatment Patterns and Outcomes in Elderly Patients Newly Diagnosed With Acute Myeloid Leukemia: A Retrospective Analysis of Electronic Medical Records From US Community Oncology Practices. AB - BACKGROUND: Many elderly patients with acute myeloid leukemia (AML) are considered ineligible for standard intensive induction therapy due to performance status and comorbidities. We analyzed treatment patterns and outcomes among elderly patients newly diagnosed with AML in the US community oncology setting. METHODS: A retrospective observational study was conducted using patient-level data from a network of US community oncology practices provided by Altos Solutions. Patients aged >= 60 years, diagnosed with AML between November 2005 and February 2014, with >= 1 recorded visit and >= 6 months between diagnosis and data cutoff, were included. Only patients who received active treatment or best supportive care (BSC) per National Comprehensive Cancer Network (NCCN) AML Guidelines were analyzed. RESULTS: Of 1139 patients meeting the inclusion criteria, 922 (median age 76 years) received NCCN-recommended treatments: standard induction (n = 5), low-intensity therapy (n = 425), BSC with hydroxyurea (HU) (n = 36), or BSC without HU (n = 455). For the low-intensity therapy cohort, median time from diagnosis to treatment initiation was 17 days; median duration of therapy was 5.1 months. Median overall survival (OS) from diagnosis in the low intensity, BSC with HU, and BSC without HU groups was 12.3, 7.0, and 49.4 months, respectively. Median time to next therapy/death was 10.1 months in patients receiving low-intensity therapy. A higher proportion of patients receiving low intensity therapy required transfusion or other supportive care versus those receiving BSC. CONCLUSIONS: As expected, OS in patients receiving low-intensity therapy or BSC with HU is poor for elderly patients with AML. Remarkably, intensive induction strategies are rarely used for older patients in community oncology practice. PMID- 27686690 TI - Glutathione S-Transferase T1 (GSTT1) Null Polymorphism, Smoking, and Their Interaction in Coronary Heart Disease: A Comprehensive Meta-Analysis. AB - BACKGROUND: The association between glutathione S-transferase T1 (GSTT1) null polymorphism and coronary heart disease (CHD) is inconsistent among studies, and data on the GSTT1 null genotype-smoking interplay in CHD is lacking. We conducted this meta-analysis to investigate the relationship between GSTT1 null polymorphism and CHD and to assess the potential interaction between GSTT1 null genotype and smoking. METHODS: PubMed and EMBASE databases were searched up to 27 January 2016 using the appropriate terms. Odds ratios were pooled using either fixed-effects or random-effects models. RESULTS: Twenty-nine articles including 31 studies with 15,004 cases and 35,597 controls were eligible. The random effects model showed that the GSTT1 null genotype was associated with increased CHD risk (OR=1.213, 95%CI: 1.004-1.467; I2=90.4%). After excluding 10 studies detected by Galbraith plot, the fixed effects summary estimate also showed an increased risk of CHD (OR=1.14, 95% CI: 1.06-1.22; I2=27.7%). A case-only analysis including eight studies showed a statistically significant positive interaction between GSTT1 null polymorphism and smoking status on CHD (OR=1.34, 95% CI: 1.09-1.64; I2=0%). Sensitivity analyses further supported the associations. No publication bias was observed. CONCLUSIONS: This meta-analysis suggests that GSTT1 null polymorphism is associated with the risk of CHD. To our knowledge, this is the first meta-analysis to prove a positive effect of the interaction between GSTT1 null genotype and smoking status on the risk of CHD. Future studies with detailed individual information are needed to confirm our findings. PMID- 27686691 TI - Functional Effects of Bulbospongiosus Muscle Sparing on Ejaculatory Function and Post-Void Dribbling after Bulbar Urethroplasty. AB - PURPOSE: Bulbar urethroplasty outcomes studies have shown low but significant rates of post-void dribbling and ejaculatory dysfunction. The bulbospongiosus muscle is involved with the expulsion of seminal fluid and urine from the bulbar urethra and, thus, we hypothesized that performing urethroplasty using a technique that does not split the muscle may result in better postoperative patient reported ejaculatory function and less post-void dribbling. MATERIALS AND METHODS: We performed a multi-institutional matched, case-control analysis comparing men treated with a bulbospongiosus sparing technique to men treated with the traditional nonbulbospongiosus sparing technique. Preoperative and postoperative (3 to 12 months) ejaculatory function was assessed using the 4 ejaculatory questions of the Male Sexual Health Questionnaire short form as well as a patient perception questionnaire. Post-void dribbling was assessed using a validated urethroplasty questionnaire. RESULTS: A total of 25 patients who underwent bulbospongiosus sparing urethroplasty and 25 who underwent nonbulbospongiosus sparing urethroplasty were matched by total preoperative Male Sexual Health Questionnaire score, age, and performance of excision and primary anastomosis. The bulbospongiosus sparing and nonbulbospongiosus sparing groups had similar postoperative total Male Sexual Health Questionnaire scores (15.24 vs 15.40, respectively, p=0.90) and there were no significant postoperative questionnaire score changes in either group (bulbospongiosus sparing 14.56 to 15.24, p=0.4; nonbulbospongiosus sparing 14.64 vs 15.40, p=0.44). Individual responses to the Male Sexual Health Questionnaire were analyzed and no statistically significant difference was found between the groups. Rates of postoperative post-void dribbling and perception of ejaculatory function were similar between the groups. CONCLUSIONS: Sparing the bulbospongiosus muscle during urethroplasty does not seem to have a significant impact on patient reported ejaculatory function or post-void dribbling compared with nonbulbospongiosus sparing urethroplasty at early followup. PMID- 27686692 TI - Metabolic syndrome in breast cancer survivors with high carbohydrate consumption: The first report in community setting. AB - BACKGROUND & AIMS: This study was conducted to examine the prevalence of and lifestyle factors associated with the metabolic syndrome in breast cancer survivors and to compare those factors with controls without cancer in a community setting. METHODS: This study included 584 female breast cancer survivors >=3 years after the initial diagnosis and 2336 age-matched cancer-free female controls from 39 community health examination centers located in 14 urban areas in Korea. The prevalence of the metabolic syndrome is shown. Factors associated with the metabolic syndrome were analyzed as odds ratios (ORs) in cancer survivors and controls; differences between the two groups in the ORs of associated factors were evaluated by calculating p-heterogeneity values. RESULTS: The prevalence of metabolic syndrome in breast cancer survivors and age-matched controls were 26.8% and 26.9%, respectively. Higher percentage of caloric intake from carbohydrates was associated with increased metabolic syndrome only in the breast cancer survivors (OR for the highest vs. lowest quartile for survivors = 2.48 [95% CI = 1.20-5.14]; OR for controls = 1.11 [95% CI = 0.81-1.51]; P heterogeneity = 0.046). Sweat-inducing exercise for >=150 min/week was associated with a lower risk of metabolic syndrome only in controls (controls: OR = 0.72 [95% CI = 0.58-0.89]; survivors: OR = 0.88 [95% CI = 0.57-1.36]). Older age, higher body mass index, and a lower education level (<=12 years) was associated with an increased prevalence of metabolic syndrome in both groups. CONCLUSIONS: Our results suggest that, in regions with excess carbohydrate intake, the association of the metabolic syndrome with percentage of caloric intake from carbohydrate might be more prominent than exercise in breast cancer survivors, compared with general population. PMID- 27686693 TI - Carbohydrates and insulin resistance in clinical nutrition: Recommendations from the ESPEN expert group. AB - Growing evidence underscores the important role of glycemic control in health and recovery from illness. Carbohydrate ingestion in the diet or administration in nutritional support is mandatory, but carbohydrate intake can adversely affect major body organs and tissues if resulting plasma glucose becomes too high, too low, or highly variable. Plasma glucose control is especially important for patients with conditions such as diabetes or metabolic stress resulting from critical illness or surgery. These patients are particularly in need of glycemic management to help lessen glycemic variability and its negative health consequences when nutritional support is administered. Here we report on recent findings and emerging trends in the field based on an ESPEN workshop held in Venice, Italy, 8-9 November 2015. Evidence was discussed on pathophysiology, clinical impact, and nutritional recommendations for carbohydrate utilization and management in nutritional support. The main conclusions were: a) excess glucose and fructose availability may exacerbate metabolic complications in skeletal muscle, adipose tissue, and liver and can result in negative clinical impact; b) low-glycemic index and high-fiber diets, including specialty products for nutritional support, may provide metabolic and clinical benefits in individuals with obesity, insulin resistance, and diabetes; c) in acute conditions such as surgery and critical illness, insulin resistance and elevated circulating glucose levels have a negative impact on patient outcomes and should be prevented through nutritional and/or pharmacological intervention. In such acute settings, efforts should be implemented towards defining optimal plasma glucose targets, avoiding excessive plasma glucose variability, and optimizing glucose control relative to nutritional support. PMID- 27686694 TI - Current interventional strategy for the treatment of hepatic alveolar echinococcosis. AB - INTRODUCTION: The use of various types of invasive interventions combined with anti-infective drugs in the therapeutic strategy of alveolar echinococcosis (AE) has changed during the last 30 years. Areas covered: This article reviews the current respective indications of surgical, percutaneous and perendoscopic interventions in AE and proposes an integrative therapeutic strategy. Expert commentary: Hepatic resection is indicated whenever it is feasible and curative; palliative surgery should be avoided; percutaneous procedures are best adapted to the drainage of the necrotic cavity present in advanced cases; perendoscopic procedures with stenting are best adapted to alleviating the biliary complications that are common and life-threatening in AE patients. Continuous administration of albendazole or mebendazole, without interruption is mandatory in all cases, temporarily (recommended duration: 2 years) after radical lesion resection in patients without immune suppression; for life in all other cases. Long-term follow-up is essential. PMID- 27686695 TI - Selecting symptom instruments for cardiovascular populations. AB - The purpose of this review is to provide a guide for researchers and clinicians in selecting an instrument to measure four commonly occurring symptoms (dyspnea, chest pain, palpitations, and fatigue) in cardiac populations (acute coronary syndrome, heart failure, arrhythmia/atrial fibrillation, and angina, or patients undergoing cardiac interventions). An integrative review of the literature was conducted. A total of 102 studies summarizing information on 36 different instruments are reported in this integrative review. The majority of the instruments measured multiple symptoms and were used for one population. A majority of the symptom measures were disease-specific and were multi dimensional. This review summarizes the psychometrics and defining characteristics of instruments to measure the four commonly occurring symptoms in cardiac populations. Simple, psychometrically strong instruments do exist and should be considered for use; however, there is less evidence of responsiveness to change over time for the majority of instruments. PMID- 27686696 TI - Development of a methodology for in vivo follow-up of hepatocellular carcinoma in hepatocyte specific Trim24-null mice treated with myo-inositol trispyrophosphate. AB - BACKGROUND: Genetically induced hepatocellular carcinoma (HCC) models are generally used to investigate carcinogenesis pathways, but very few attempts were made to valorize them for pharmacological testing. This study describes a micro computed tomography (micro-CT) - based methodology for the diagnostic and lifelong follow-up of HCC in the hepatocyte-specific Trim24-null mouse line. Myo inositol trispyrophosphate (ITPP) was tested as anti-cancer drug. METHODS: Partial hepatectomy was performed in 2 months-old Trim24-null mice, in order to accelerate the carcinogenesis process. HCC diagnosis was obtained by micro-CT scan with double contrast agent: 10 MUl/g FenestraTM LC was injected intraperitoneally 6 h prior to imaging and 10 MUl/g FenestraTM VC was injected intravenously 15 min prior to imaging. Twenty three hepatocyte-specific Trim24 null mice were considered for ITPP testing (3 mg/g/week intraperitoneally during 10 months in 12 mice, versus 11 controls). Lifelong follow-up was performed using micro-CT. Comparative analysis was performed using unpaired t test with Welch correction and survival curves were compared by log-rank test. Gene expression analysis was performed using the RT q-PCR technique. RESULTS: Double contrast micro-CT scan allowed HCC diagnosis as hypodense, isodense or hyperdense nodules. Positive predictive value was 81.3 %. Negative predictive value was 83.3 %. Tumor growth could be objectified by micro-CT scan before the ITPP treatment was started, and at 3 and 9 months follow-up. Significant progression of tumor volume was demonstrated in the both groups, with no difference between groups (p > 0.05). In the ITPP group, a mild decrease in tumor doubling time was first observed (31.9 +/- 12 days, p > 0.05) followed by a significant increase (59.8 +/ 18.3 days, p = 0.008). However, tumor doubling time was not different between groups (p > 0.05). Median survival after treatment initiation was 223 days (controls) versus 296 days (ITPP group, p = 0.0027). HIF1alpha, VEGF, glutamine synthase, osteopontin expression levels were not significantly modified at the end of follow-up. In the ITPP group, the p53 expression profile was inversed as compared to the control group, higher in non-tumor livers than in tumors. CONCLUSION: ITPP treatment allowed for a two-month survival improvement, with better tolerance of tumor burden and apoptosis increase in non-tumor, pathological livers. PMID- 27686697 TI - Patient Discussion About Sexual Health With Health Care Providers After Cancer-A National Survey. AB - INTRODUCTION: A discussion about sexuality should become a routine part of the personalized care pathway for patients with cancer. AIM: To assess rates of patient discussion about sexuality with health care providers after cancer. METHODS: We used data from the representative French nationwide 2012 VICAN survey, which included 4,349 adults 18 to 82 years old who were still alive 2 years after diagnosis at 12 cancer sites. MAIN OUTCOME MEASURES: Self-reported rates of discussion about sexuality with health care providers were assessed, and associated factors were tested after systematic adjustment for a sexual health indicator (created from six items of the Relationship and Sexuality Scale). RESULTS: Of 4,181 respondents to the question on a discussion about sexuality, 54.7% reported that nobody had proposed a discussion to them, 21.9% did not want any discussion, and 23.4% had had a discussion. Women had less discussion about sexuality with health care providers (11.1% vs 36.7% of men, P < .001) and were more likely to request a discussion at their own initiative (62.9% vs 48.0% of men, P < .001). Discussion about sexuality was more frequent with patients with prostate (56.3%) and cervical (39.6%) cancer, but increasing age was associated with a greater reluctance to discuss this issue (odds ratio = 1.17, 95% CI = 1.04 1.2). The likelihood of discussion increased with severe sexual problems, radiotherapy, general sequelae, having an information-seeker profile, previous professional psychological help, and initial treatment in private centers. Patients initially wishing for psychological help were more likely to desire a discussion about sexuality. CONCLUSION: Sexuality receives little attention in French patients with cancer. Inequalities in the discussion about sexuality were observed in relation to the type of care center where the patient was initially managed. Information on supportive interventions, including more systematic referral for professional psychological help, should be developed to facilitate discussion and should be offered to all patients, irrespective of severity of sexual problems, age, sex, cancer site, and care center. PMID- 27686698 TI - Characterization of EEG patterns in brain-injured subjects and controls after a Snoezelen((r)) intervention. AB - BACKGROUND AND OBJECTIVE: The aim of this study was to assess the changes induced in electroencephalographic (EEG) activity by a Snoezelen((r)) intervention on individuals with brain-injury and control subjects. METHODS: EEG activity was recorded preceding and following a Snoezelen((r)) session in 18 people with cerebral palsy (CP), 18 subjects who have sustained traumatic brain-injury (TBI) and 18 controls. EEG data were analyzed by means of spectral and nonlinear measures: median frequency (MF), individual alpha frequency (IAF), sample entropy (SampEn) and Lempel-Ziv complexity (LZC). RESULTS: Our results showed decreased values for MF, IAF, SampEn and LZC as a consequence of the therapy. The main changes between pre-stimulation and post-stimulation conditions were found in occipital and parietal brain areas. Additionally, these changes are more widespread in controls than in brain-injured subjects, which can be due to cognitive deficits in TBI and CP groups. CONCLUSIONS: Our findings support the notion that Snoezelen((r)) therapy affects central nervous system, inducing a slowing of oscillatory activity, as well as a decrease of EEG complexity and irregularity. These alterations seem to be related with higher levels of relaxation of the participants. PMID- 27686699 TI - Supervised discretization can discover risk groups in cancer survival analysis. AB - Discretization of continuous variables is a common practice in medical research to identify risk patient groups. This work compares the performance of gold standard categorization procedures (TNM+A protocol) with that of three supervised discretization methods from Machine Learning (CAIM, ChiM and DTree) in the stratification of patients with breast cancer. The performance for the discretization algorithms was evaluated based on the results obtained after applying standard survival analysis procedures such as Kaplan-Meier curves, Cox regression and predictive modelling. The results show that the application of alternative discretization algorithms could lead the clinicians to get valuable information for the diagnosis and outcome of the disease. Patient data were collected from the Medical Oncology Service of the Hospital Clinico Universitario (Malaga, Spain) considering a follow up period from 1982 to 2008. PMID- 27686700 TI - Study of heat transfer on physiological driven movement with CNT nanofluids and variable viscosity. AB - BACKGROUND AND OBJECTIVES: With ongoing interest in CNT nanofluids and materials in biotechnology, energy and environment, microelectronics, composite materials etc., the current investigation is carried out to analyze the effects of variable viscosity and thermal conductivity of CNT nanofluids flow driven by cilia induced movement through a circular cylindrical tube. Metachronal wave is generated by the beating of cilia and mathematically modeled as elliptical wave propagation by Blake (1971). METHODS, RESULTS AND CONCLUSIONS: The problem is formulated in the form of nonlinear partial differential equations, which are simplified by using the dimensional analysis to avoid the complicacy of dimensional homogeneity. Lubrication theory is employed to linearize the governing equations and it is also physically appropriate for cilia movement. Analytical solutions for velocity, temperature and pressure gradient and stream function are obtained. The analytical results are numerically simulated by using the Mathematica Software and plotted the graphs for velocity profile, temperature profile, pressure gradient and stream lines for better discussion and visualization. This model is applicable in physiological transport phenomena to explore the nanotechnology in engineering the artificial cilia and ciliated tube/pipe. PMID- 27686701 TI - GPU accelerated dynamic respiratory motion model correction for MRI-guided cardiac interventions. AB - BACKGROUND AND OBJECTIVES: The use of pre-procedural magnetic resonance (MR) roadmap images for interventional guidance has limited anatomical accuracy due to intra-procedural respiratory motion of the heart. Therefore, the objective of this study is to explore the use of a rapidly updated dynamic motion model to correct for respiratory motion induced errors during MRI-guided cardiac interventions. The motivation for the proposed technique is to improve the accuracy of MRI guidance by taking advantage of the anatomical context provided by the high resolution prior images and the respiratory motion information present in a series of realtime MR images. METHODS: We implemented a GPU accelerated image registration algorithm to derive the respiratory motion information and used the resulting transformation parameters to update an adaptive motion model once every heart cycle. In the subsequent heart cycle, the dynamic motion model could be used to predict the respiratory motion and provide a motion estimate to realign the prior volume with the realtime MR image. This iterative update and prediction process is then continuously repeated. RESULTS: The GPU accelerated image registration algorithm could be completed in an average of 176.9 +/- 14.0 ms, which is 139* faster than a CPU implementation. Thus, it was feasible to update the dynamic model once every heart cycle. The proposed dynamic model was also able to improve the registration accuracy from 86.0 +/- 7.5% to 93.0 +/- 3.3% in case of variable breathing patterns, as evaluated by the dice similarity coefficient of the left ventricular border overlap between the prior and realtime images. CONCLUSIONS: The feasibility of a dynamic motion correction framework was demonstrated. The resulting improvements may lead to more accurate MRI-guided cardiac interventions in the future. PMID- 27686702 TI - Predicting intentions of nurses to adopt patient personal health records: A structural equation modeling approach. AB - OBJECTIVE: The American Nurses Association endorsed the use of online patient personal health records (PHRs) and challenged all nurses to obtain the health records of patients. However, few studies have explored the factors associated with the intentions of nurses to use patient PHRs. Our study used an extended technology acceptance model, with the theory of planned behavior and perceived credibility, to explore factors associated with the intentions of nurses to use patient PHRs. METHODS: This cross-sectional quantitative study comprised a sample of 635 nurses who had worked full time for at least 3 months, and they were recruited from three hospitals affiliated with a university in northern Taiwan. We used a questionnaire to obtain information on perceived usefulness, perceived ease of use, perceived credibility, subjective norms, computer self-efficacy, attitudes, and intentions to use patient PHRs. RESULTS: This study indicated that perceived usefulness, computer self-efficacy, and subjective norms significantly and positively affected intentions to use patient PHRs. The attitudes of nurses toward PHR adoption directly influenced their intentions to use patient PHRs. Moreover, subjective norms indirectly affected intentions to use patient PHRs through the factor of attitudes. The proposed model explained 82.1% of the variance in the intentions of nurses to use patient PHRs. CONCLUSIONS: Subjective norms had stronger total effects on the attitudes and intentions of nurses to use patient PHRs than perceived usefulness, perceived ease of use, or perceived credibility did. The results may help practitioners further understand that the attitudes of nurses toward using patient PHRs are influenced by peer groups and administrators. The current study provides evidence that peer groups influence the attitudes of nurses to use patient PHRs, which in turn influence their intentions toward PHR adoption. PMID- 27686703 TI - Traumatic brain injury in pedestrian-vehicle collisions: Convexity and suitability of some functionals used as injury metrics. AB - BACKGROUND AND OBJECTIVE: Abrupt accelerations or decelerations can cause large strain in brain tissues and, consequently, different forms of Traumatic Brain Injury (TBI). In order to predict the effect of the accelerations on the soft tissues of the brain, many different injury metrics have been proposed (typically, an injury metric is a real valued functional of the accelerations). The objective of this article is to make a formal and empirical comparison, in order to identify general criteria for reasonable injury metrics, and propose a general guideline to avoid ill-proposed injury metrics. METHODS: A medium-sized sample of vehicle-pedestrian collisions, from Post Mortem Human Subject (PMHS) tests, is analyzed. A statistical study has been conducted in order to determine the discriminant power of the usual metrics. We use Principal Component Analysis to reduce dimensionality and to check consistency among the different metrics. In addition, this article compares the mathematical properties of some of these functionals, trying to identify the desirable properties that any of those functionals needs to fulfill in order to be useful for optimization. RESULTS: We have found a pair-wise consistency of all the currently used metrics (any two injury metrics are always positively related). In addition, we observed that two independent principal factors explain about 72.5% of the observed variance among all collision tests. This is remarkable because it indicates that despite high number of different injury metrics, a reduced number of variables can explain the results of all these metrics. With regard to the formal properties, we found that essentially all injury mechanisms can be accounted by means of scalable, differentiable and convex functionals (we propose to call minimization suitable injury metric any metric having these three formal properties). In addition three useful functionals, usable as injury metrics, are identified on the basis of the empirical comparisons. CONCLUSIONS: The commonly used metrics are highly consistent, but also highly redundant. Formal minimal conditions of a reasonable injury metric has been identified. Future proposals of injury metrics can benefit from the results of this study. PMID- 27686704 TI - Automatic identification of epileptic seizures from EEG signals using linear programming boosting. AB - BACKGROUND AND OBJECTIVE: Computerized epileptic seizure detection is essential for expediting epilepsy diagnosis and research and for assisting medical professionals. Moreover, the implementation of an epilepsy monitoring device that has low power and is portable requires a reliable and successful seizure detection scheme. In this work, the problem of automated epilepsy seizure detection using singe-channel EEG signals has been addressed. METHODS: At first, segments of EEG signals are decomposed using a newly proposed signal processing scheme, namely complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN). Six spectral moments are extracted from the CEEMDAN mode functions and train and test matrices are formed afterward. These matrices are fed into the classifier to identify epileptic seizures from EEG signal segments. In this work, we implement an ensemble learning based machine learning algorithm, namely linear programming boosting (LPBoost) to perform classification. RESULTS: The efficacy of spectral features in the CEEMDAN domain is validated by graphical and statistical analyses. The performance of CEEMDAN is compared to those of its predecessors to further inspect its suitability. The effectiveness and the appropriateness of LPBoost are demonstrated as opposed to the commonly used classification models. Resubstitution and 10 fold cross-validation error analyses confirm the superior algorithm performance of the proposed scheme. The algorithmic performance of our epilepsy seizure identification scheme is also evaluated against state-of-the-art works in the literature. Experimental outcomes manifest that the proposed seizure detection scheme performs better than the existing works in terms of accuracy, sensitivity, specificity, and Cohen's Kappa coefficient. CONCLUSION: It can be anticipated that owing to its use of only one channel of EEG signal, the proposed method will be suitable for device implementation, eliminate the onus of clinicians for analyzing a large bulk of data manually, and expedite epilepsy diagnosis. PMID- 27686705 TI - A new computer vision-based approach to aid the diagnosis of Parkinson's disease. AB - BACKGROUND AND OBJECTIVE: Even today, pointing out an exam that can diagnose a patient with Parkinson's disease (PD) accurately enough is not an easy task. Although a number of techniques have been used in search for a more precise method, detecting such illness and measuring its level of severity early enough to postpone its side effects are not straightforward. In this work, after reviewing a considerable number of works, we conclude that only a few techniques address the problem of PD recognition by means of micrography using computer vision techniques. Therefore, we consider the problem of aiding automatic PD diagnosis by means of spirals and meanders filled out in forms, which are then compared with the template for feature extraction. METHODS: In our work, both the template and the drawings are identified and separated automatically using image processing techniques, thus needing no user intervention. Since we have no registered images, the idea is to obtain a suitable representation of both template and drawings using the very same approach for all images in a fast and accurate approach. RESULTS: The results have shown that we can obtain very reasonable recognition rates (around ~67%), with the most accurate class being the one represented by the patients, which outnumbered the control individuals in the proposed dataset. CONCLUSIONS: The proposed approach seemed to be suitable for aiding in automatic PD diagnosis by means of computer vision and machine learning techniques. Also, meander images play an important role, leading to higher accuracies than spiral images. We also observed that the main problem in detecting PD is the patients in the early stages, who can draw near-perfect objects, which are very similar to the ones made by control patients. PMID- 27686706 TI - Intraoral radiographs texture analysis for dental implant planning. AB - BACKGROUND AND OBJECTIVES: Computer vision extracts features or attributes from images improving diagnosis accuracy and aiding in clinical decisions. This study aims to investigate the feasibility of using texture analysis of periapical radiograph images as a tool for dental implant treatment planning. METHODS: Periapical radiograph images of 127 jawbone sites were obtained before and after implant placement. From the superimposition of the pre- and post-implant images, four regions of interest (ROI) were delineated on the pre-implant images for each implant site: mesial, distal and apical peri-implant areas and a central area. Each ROI was analysed using Matlab(r) software and seven image attributes were extracted: mean grey level (MGL), standard deviation of grey levels (SDGL), coefficient of variation (CV), entropy (En), contrast, correlation (Cor) and angular second moment (ASM). Images were grouped by bone types-Lekholm and Zarb classification (1,2,3,4). Peak insertion torque (PIT) and resonance frequency analysis (RFA) were recorded during implant placement. Differences among groups were tested for each image attribute. Agreement between measurements of the peri implant ROIs and overall ROI (peri-implant + central area) was tested, as well as the association between primary stability measures (PIT and RFA) and texture attributes. RESULTS: Differences among bone type groups were found for MGL (p = 0.035), SDGL (p = 0.024), CV (p < 0.001) and En (p < 0.001). The apical ROI showed a significant difference from the other regions for all attributes, except Cor. Concordance correlation coefficients were all almost perfect (rho > 0.93), except for ASM (rho = 0.62). Texture attributes were significantly associated with the implant stability measures. CONCLUSION: Texture analysis of periapical radiographs may be a reliable non-invasive quantitative method for the assessment of jawbone and prediction of implant stability, with potential clinical applications. PMID- 27686707 TI - Correlation coefficient based supervised locally linear embedding for pulmonary nodule recognition. AB - BACKGROUND AND OBJECTIVE: Dimensionality reduction techniques are developed to suppress the negative effects of high dimensional feature space of lung CT images on classification performance in computer aided detection (CAD) systems for pulmonary nodule detection. METHODS: An improved supervised locally linear embedding (SLLE) algorithm is proposed based on the concept of correlation coefficient. The Spearman's rank correlation coefficient is introduced to adjust the distance metric in the SLLE algorithm to ensure that more suitable neighborhood points could be identified, and thus to enhance the discriminating power of embedded data. The proposed Spearman's rank correlation coefficient based SLLE (SC(2)SLLE) is implemented and validated in our pilot CAD system using a clinical dataset collected from the publicly available lung image database consortium and image database resource initiative (LICD-IDRI). Particularly, a representative CAD system for solitary pulmonary nodule detection is designed and implemented. After a sequential medical image processing steps, 64 nodules and 140 non-nodules are extracted, and 34 representative features are calculated. The SC(2)SLLE, as well as SLLE and LLE algorithm, are applied to reduce the dimensionality. Several quantitative measurements are also used to evaluate and compare the performances. RESULTS: Using a 5-fold cross-validation methodology, the proposed algorithm achieves 87.65% accuracy, 79.23% sensitivity, 91.43% specificity, and 8.57% false positive rate, on average. Experimental results indicate that the proposed algorithm outperforms the original locally linear embedding and SLLE coupled with the support vector machine (SVM) classifier. CONCLUSIONS: Based on the preliminary results from a limited number of nodules in our dataset, this study demonstrates the great potential to improve the performance of a CAD system for nodule detection using the proposed SC(2)SLLE. PMID- 27686708 TI - Integrating evolutionary game theory into an agent-based model of ductal carcinoma in situ: Role of gap junctions in cancer progression. AB - BACKGROUND AND OBJECTIVE: There are many cells with various phenotypic behaviors in cancer interacting with each other. For example, an apoptotic cell may induce apoptosis in adjacent cells. A living cell can also protect cells from undergoing apoptosis and necrosis. These survival and death signals are propagated through interaction pathways between adjacent cells called gap junctions. The function of these signals depends on the cellular context of the cell receiving them. For instance, a receiver cell experiencing a low level of oxygen may interpret a received survival signal as an apoptosis signal. In this study, we examine the effect of these signals on tumor growth. METHODS: We make an evolutionary game theory component in order to model the signal propagation through gap junctions. The game payoffs are defined as a function of cellular context. Then, the game theory component is integrated into an agent-based model of tumor growth. After that, the integrated model is applied to ductal carcinoma in situ, a type of early stage breast cancer. Different scenarios are explored to observe the impact of the gap junction communication and parameters of the game theory component on cancer progression. We compare these scenarios by using the Wilcoxon signed-rank test. RESULTS: The Wilcoxon signed-rank test succeeds in proving a significant difference between the tumor growth of the model before and after considering the gap junction communication. The Wilcoxon signed-rank test also proves that the tumor growth significantly depends on the oxygen threshold of turning survival signals into apoptosis. CONCLUSIONS: In this study, the gap junction communication is modeled by using evolutionary game theory to illustrate its role at early stage cancers such as ductal carcinoma in situ. This work indicates that the gap junction communication and the oxygen threshold of turning survival signals into apoptosis can notably affect cancer progression. PMID- 27686709 TI - Improving the text classification using clustering and a novel HMM to reduce the dimensionality. AB - In text classification problems, the representation of a document has a strong impact on the performance of learning systems. The high dimensionality of the classical structured representations can lead to burdensome computations due to the great size of real-world data. Consequently, there is a need for reducing the quantity of handled information to improve the classification process. In this paper, we propose a method to reduce the dimensionality of a classical text representation based on a clustering technique to group documents, and a previously developed Hidden Markov Model to represent them. We have applied tests with the k-NN and SVM classifiers on the OHSUMED and TREC benchmark text corpora using the proposed dimensionality reduction technique. The experimental results obtained are very satisfactory compared to commonly used techniques like InfoGain and the statistical tests performed demonstrate the suitability of the proposed technique for the preprocessing step in a text classification task. PMID- 27686710 TI - Profiling intra-patient type I diabetes behaviors. AB - BACKGROUND: The large intra-patient variability in type 1 diabetic patients dramatically reduces the ability to achieve adequate blood glucose control. A novel methodology to identify different blood glucose dynamics profiles will allow therapies to be more accurate and tailored according to patient's conditions and to the situations faced by patients (exercise, week-ends, holidays, menstruation, etc). MATERIALS AND METHODS: A clustering methodology based on the normalized compression distance is applied to identify different profiles for diabetic patients. First, the methodology is validated using "in silico" data from 10 patients in 3 different scenarios: days without exercise, poor controlled exercise days and days with well-controlled exercise. Second, we perform a series of in vivo experiments using data from 10 patients assessing the ability of the proposed methodology in real scenarios. RESULTS: In silico experiments show that the methodology is able to identify poor and well controlled days in theoretical scenarios. In vivo experiments present meaningful profiles for working days, bank days and other situations, where different insulin requirements were detected. CONCLUSIONS: A tool for profiling blood glucose dynamics of patients can be implemented in a short term to enhance existing analysis platforms using combined CGM-CSII systems. Besides coping with the information overload, the tool will assist physicians to adjust and improve insulin therapy and patients in the self-management of the disease. PMID- 27686711 TI - Dynamic ECG features for atrial fibrillation recognition. AB - BACKGROUND: Atrial fibrillation (AF) can cause the formation of blood clots in the heart. The clots may move to the brain and cause a stroke. Therefore, this study analyzed the ECG features of AF and normal sinus rhythm signals for AF recognition which were extracted by using a second-order dynamic system (SODS) concept. OBJECTIVE: To find the appropriate windowing length for feature extraction based on SODS and to determine a machine learning method that could provide higher accuracy in recognizing AF. METHOD: ECG features were extracted based on a dynamic system (DS) that uses a second-order differential equation to describe the short-term behavior of ECG signals according to the natural frequency (omega), damping coefficient, (xi), and forcing input (u). The extracted features were windowed into 2, 3, 4, 6, 8, and 10 second episodes to find the appropriate windowing size for AF signal processing. ANOVA and t-tests were used to determine the significant features. In addition, pattern recognition machine learning methods (an artificial neural network (ANN) and a support vector machine (SVM)) with k-fold cross validation (k-CV) were used to develop the ECG recognition system. RESULTS: Significant differences (p < 0.0001) were observed among all ECG groups (NSR, N, AF) using 2, 3, 4 and 6 second episodes for the features omega and u/omega; 4, 6 and 8 second episodes for features omega and u; 4 and 6 second episodes for features omega, u and u/omega, and; 10 second episodes for the feature xi. The highest accuracy for AF recognition (AF, NSR) using ANN with k-CV was 95.3% using combination of features (omega and u; omega, u and u/omega) and SVM with k-CV was 95.0% using a combination of features omega, u and u/omega. CONCLUSION: This study found that 4 s is the most appropriate windowing length, using two features (omega and u) for AF detection with an accuracy of 95.3%. Moreover, the pattern recognition learning machine uses an ANN with 10-fold cross validation based on DS.

AB - BACKGROUND AND OBJECTIVE: Depression has become a major health burden worldwide, and effectively detection of such disorder is a great challenge which requires latest technological tool, such as Electroencephalography (EEG). This EEG-based research seeks to find prominent frequency band and brain regions that are most related to mild depression, as well as an optimal combination of classification algorithms and feature selection methods which can be used in future mild depression detection. METHODS: An experiment based on facial expression viewing task (Emo_block and Neu_block) was conducted, and EEG data of 37 university students were collected using a 128 channel HydroCel Geodesic Sensor Net (HCGSN). For discriminating mild depressive patients and normal controls, BayesNet (BN), Support Vector Machine (SVM), Logistic Regression (LR), k-nearest neighbor (KNN) and RandomForest (RF) classifiers were used. And BestFirst (BF), GreedyStepwise (GSW), GeneticSearch (GS), LinearForwordSelection (LFS) and RankSearch (RS) based on Correlation Features Selection (CFS) were applied for linear and non-linear EEG features selection. Independent Samples T-test with Bonferroni correction was used to find the significantly discriminant electrodes and features. RESULTS: Data mining results indicate that optimal performance is achieved using a combination of feature selection method GSW based on CFS and classifier KNN for beta frequency band. Accuracies achieved 92.00% and 98.00%, and AUC achieved 0.957 and 0.997, for Emo_block and Neu_block beta band data respectively. T-test results validate the effectiveness of selected features by search method GSW. Simplified EEG system with only FP1, FP2, F3, O2, T3 electrodes was also explored with linear features, which yielded accuracies of 91.70% and 96.00%, AUC of 0.952 and 0.972, for Emo_block and Neu_block respectively. CONCLUSIONS: Classification results obtained by GSW + KNN are encouraging and better than previously published results. In the spatial distribution of features, we find that left parietotemporal lobe in beta EEG frequency band has greater effect on mild depression detection. And fewer EEG channels (FP1, FP2, F3, O2 and T3) combined with linear features may be good candidates for usage in portable systems for mild depression detection. PMID- 27686713 TI - Cardiac arrhythmia beat classification using DOST and PSO tuned SVM. AB - BACKGROUND AND OBJECTIVE: The increase in the number of deaths due to cardiovascular diseases (CVDs) has gained significant attention from the study of electrocardiogram (ECG) signals. These ECG signals are studied by the experienced cardiologist for accurate and proper diagnosis, but it becomes difficult and time consuming for long-term recordings. Various signal processing techniques are studied to analyze the ECG signal, but they bear limitations due to the non stationary behavior of ECG signals. Hence, this study aims to improve the classification accuracy rate and provide an automated diagnostic solution for the detection of cardiac arrhythmias. METHODS: The proposed methodology consists of four stages, i.e. filtering, R-peak detection, feature extraction and classification stages. In this study, Wavelet based approach is used to filter the raw ECG signal, whereas Pan-Tompkins algorithm is used for detecting the R peak inside the ECG signal. In the feature extraction stage, discrete orthogonal Stockwell transform (DOST) approach is presented for an efficient time-frequency representation (i.e. morphological descriptors) of a time domain signal and retains the absolute phase information to distinguish the various non-stationary behavior ECG signals. Moreover, these morphological descriptors are further reduced in lower dimensional space by using principal component analysis and combined with the dynamic features (i.e based on RR-interval of the ECG signals) of the input signal. This combination of two different kinds of descriptors represents each feature set of an input signal that is utilized for classification into subsequent categories by employing PSO tuned support vector machines (SVM). RESULTS: The proposed methodology is validated on the baseline MIT-BIH arrhythmia database and evaluated under two assessment schemes, yielding an improved overall accuracy of 99.18% for sixteen classes in the category-based and 89.10% for five classes (mapped according to AAMI standard) in the patient based assessment scheme respectively to the state-of-art diagnosis. The results reported are further compared to the existing methodologies in literature. CONCLUSIONS: The proposed feature representation of cardiac signals based on symmetrical features along with PSO based optimization technique for the SVM classifier reported an improved classification accuracy in both the assessment schemes evaluated on the benchmark MIT-BIH arrhythmia database and hence can be utilized for automated computer-aided diagnosis of cardiac arrhythmia beats. PMID- 27686715 TI - Editorial. PMID- 27686714 TI - The reliability and validity of a clinical 3D freehand ultrasound system. AB - BACKGROUND AND OBJECTIVE: Acquiring large anatomical volumes in a feasible manner is useful for clinical decision-making. A relatively new technique called 3D freehand ultrasonography is capable of this by combining a conventional 2D ultrasonography system. Currently, a thorough analysis of this technique is lacking, as the analyses are dependent on the software implementation details and the choice of measurement systems. Therefore this study starts by making this implementation available under the form of an open-source software library to perform 3D freehand ultrasonography. Following that, reliability and validity analyses of extracting volumes and lengths will be carried out using two independent motion-tracking systems. METHODS: A PC-based ultrasonography device and two optical motion-tracking systems were used for data acquisition. An in house software library called Py3DFreeHandUS was developed to reconstruct (off line) the corresponding data into one 3D data set. Reliability and validity analyses of the entire experimental set-up were performed by estimating the volumes and lengths of ground truth objects. Ten water-filled balloons and six cross-wires were used. Repeat measurements were also performed by two experienced operators. RESULTS: The software library Py3DFreeHandUS is available online, along with the relevant documentation. The reliability analyses showed high intra and inter-operator intra-class correlation coefficient results for both volumes and lengths. The accuracy analysis revealed a discrepancy in all cases of around 3%, which corresponded to 3 ml and 1 mm for volume and length measurements, respectively. Similar results were found for both of the motion-tracking systems. CONCLUSIONS: The undertaken analyses for estimating volume and lengths acquired with 3D freehand ultrasonography demonstrated reliable design measurements and suitable performance for applications that do not require sub-mm and -ml accuracy. PMID- 27686716 TI - Intestinal transport of Cylindrospermopsin using the Caco-2 cell line. AB - Cylindrospermopsin (CYN) is a cyanotoxin produced by various cyanobacterial species. It is a water soluble zwitterion, stable at extreme temperatures and pH. Despite the main route of exposure to CYN is through drinking water and food, there is a lack of data concerning its intestinal absorption and the mechanisms implicated. The aim of this study was to characterize the mechanisms involved in the intestinal absorption of CYN, using Caco-2 human cell line as a model of the intestinal epithelium. The results obtained in the present work increases the limited knowledge regarding CYN transport across the intestinal epithelium and identifies the paracellular route as an important pathway in CYN absorption. A minor carrier-mediated transcellular transport has been evidenced. This transport is not affected by low temperatures, suggesting that an active mechanism is not involved. Moreover, the transport through the intestinal monolayer is H+ and GSH dependent and Na+independent. The transport characteristics elucidated in this study prepare the ground for future studies directed at identifying transporters involved in the intestinal absorption of this toxin. PMID- 27686717 TI - A Home-Based Rehabilitation Intervention for Adults Living With HIV: A Randomized Controlled Trial. AB - A randomized controlled trial was conducted to investigate the effects of a 16 week home-based rehabilitation (HBR) intervention on the quality of life, functional mobility, and functional capacity of adult people living with HIV (PLWH) on antiretroviral therapy in KwaZulu-Natal, South Africa. The intervention was carried out by community health care workers under the supervision of a qualified physical therapist. Participants in the control group received the standard of care as well as written health advice. While participants in the intervention group showed greater improvements across all outcome measures, between-group differences were nonsignificant. HBR for PLWH is a safe means of addressing the functional deficits experienced by PLWH and appears likely to improve quality of life. A task-shifting approach may be a feasible method of meeting the varied needs of PLWH, while at the same time potentially minimizing costs to already overburdened health care systems. PMID- 27686718 TI - Microbiome and food allergy. AB - Food allergy is a common disease affecting approximately 8% of children and 5% of adults. The prevalence has increased over the last two decades, suggesting an important environmental contribution to susceptibility. Studies have identified mode of birth, pet exposure, and having older siblings as being significant risk modifying factors in the development of food allergy. With the discovery that these factors significantly impact the composition of the intestinal microbiome, which is known to play a critical role in shaping the immune system, recent studies have begun to address the role of the intestinal microbiota in the development of food allergy. Studies in human cohorts support a dysbiosis in food allergy, and limited data suggest that this dysbiosis occurs early in life, preceding the onset of sensitization. Studies from animal models have clearly shown that the composition of the intestinal microbiota confers susceptibility to food allergy, and that there are organisms such as Clostridia species that are protective in the development of food allergy. Our understanding of microbial regulation of food allergy is in its nascency, but the state of the field supports an important contribution of intestinal microbes to susceptibility. Challenges going forward are to identify commensal-derived microorganisms that could be used therapeutically to prevent or perhaps treat food allergy. PMID- 27686719 TI - Developing a water-circulating column photobioreactor for microalgal growth with low energy consumption. AB - A water-circulating column photobioreactor (WCC-PBR) was developed to decrease bubble generation time and mixing time for growing microalgal biomass at low energy consumption. Bubble generation time was decreased by 60.4% and mixing time was decreased by 41.5% owing to an enhanced solution velocity with a water pump. Bubble residence time was decreased by 31.1% and mass transfer coefficient was decreased by 0.4% owing to a reduced distance between air aerator and solution surface. Microalgal growth rate was decreased by 12.7% from 128.9mg/Lday in an air-lifting column photobioreactor (ALC-PBR) to 112.6mg/Lday in a WCC-PBR because of the decrease in residence time of bubbles and an additional shear of cells in a water pump. However, total energy consumption of a WCC-PBR with an air compressor and a water pump was lower by 21.1% than that of an ALC-PBR with only an air compressor. PMID- 27686720 TI - Comparative biogas generation from fruit peels of fluted pumpkin (Telfairia occidentalis) and its optimization. AB - This study evaluated the potentials of fluted pumpkin fruit peels for biogas generation using three different pre-treatment methods (A, B, C) and the optimization of its process parameters. The physic-chemical characteristics of the substrates revealed it to be rich in nutrients and mineral elements needed by microorganisms. Gas chromatography analysis revealed the gas composition to be within the range of 58.5+/-2.5% Methane and 27+/-3% Carbon dioxide for all the three digestions. The study revealed that combination of three pre-treatment methods enhanced enormous biogas yield from the digested substrates as against the use of two methods and no pre-treatment experiment. Optimization of the generated biogas data revealed that RSM predicted higher gas yield than ANN, the latter gives higher accuracy and efficiency than the former. It is advocated that fluted pumpkin fruit peels be used for energy generation especially in the locations of its abundance. PMID- 27686721 TI - Fermentative hydrogen production in an up-flow anaerobic biofilm reactor inoculated with a co-culture of Clostridium acetobutylicum and Desulfovibrio vulgaris. AB - Dark fermentation systems often show low H2 yields and unstable H2 production, as the result of the variability of microbial dynamics and metabolic pathways. Recent batch investigations have demonstrated that an artificial consortium of two anaerobic bacteria, Clostridium acetobutylicum and Desulfovibrio vulgaris Hildenborough, may redirect metabolic fluxes and improve H2 yields. This study aimed at evaluating the scale-up from batch to continuous H2 production in an up flow anaerobic packed-bed reactor (APBR) continuously fed with a glucose-medium. The effects of various parameters, including void hydraulic retention time (HRTv), pH, and alkalinity, on H2 production performances and metabolic pathways were investigated. The results demonstrated that a stable H2 production was reached after 3-4days of operation. H2 production rates increased significantly with decreasing HRTv from 4 to 2h. Instead, H2 yields remained almost stable despite the change in HRTv, indicating that the decrease in HRTv did not affect the global metabolism. PMID- 27686722 TI - The type of carbohydrates specifically selects microbial community structures and fermentation patterns. AB - The impact on dark fermentation of seven carbohydrates as model substrates of lignocellulosic fractions (glucose, cellobiose, microcrystalline cellulose, arabinose, xylose, xylan and wheat straw) was investigated. Metabolic patterns and bacterial communities were characterized at the end of batch tests inoculated with manure digestate. It was found that hydrogen production was linked to the sugar type (pentose or hexose) and the degree of polymerisation. Hexoses produced less hydrogen, with a specific selection of lactate-producing bacterial community structures. Maximal hydrogen production was five times higher on pentose-based substrates, with specific bacterial community structures producing acetate and butyrate as main metabolites. Low hydrogen amounts accumulated from complex sugars (cellulose, xylan and wheat straw). A relatively high proportion of the reads was affiliated to Ruminococcaceae suggesting an efficient hydrolytic activity. Knowing that the bacterial community structure is very specific to a particular substrate offers new possibilities to design more efficient H2 producing biological systems. PMID- 27686723 TI - Modelling of pretreatment and saccharification with different feedstocks and kinetic modeling of sorghum saccharification. AB - Experiments have been performed for pretreatment of sorghum, wheat straw and bamboo through high temperature alkali pretreatment with different alkaline loading and temperatures, and the data on extent of delignification in terms of the final compositions of cellulose, hemicellulose and lignin have been generated. Further, enzymatic saccharification has been carried out in all the cases to find the extent of conversion possible after 72h. The effect of different operating parameters on the extent of delignification and cellulose conversion are evaluated. This data is employed to develop a generalized multi feedstock and individual feedstock based models which can be used to determine the extent of delignification and cellulose conversion for any and specific biomass respectively with alkaline pretreatment and similar enzyme conditions as considered in the present study. Also, a kinetic model is developed and validated for sorghum for cellulosic conversion. PMID- 27686724 TI - Migration and risk assessment of heavy metals in sewage sludge during hydrothermal treatment combined with pyrolysis. AB - In this study, the immobilization and risk assessment of heavy metals (HMs) in sewage sludge (SS) during hydrothermal treatment combined with pyrolysis (HTP) was investigated. The experimental results showed that the immobilization of HMs in SS was significantly affected and that the eco-toxicity/risk of SS to the environment was reduced through HTP, in addition to the enhancement of dehydration and a reduction in the volume of the sewage sludge. After the HTP process, although the majority of HMs were accumulated in the biochar, the HMs could be transformed from bioavailable fractions to more stable fractions, such as the acid soluble/exchangeable fractions (F1) of Zn, Ni and Cd in the biochar, which decreased to less than 6.31%, 2.36% and 3.64%, respectively. Moreover, the leaching potential of HMs decreased after the HTP process. PMID- 27686725 TI - Insight into the solvent, temperature and time effects on the hydrogenolysis of hydrolyzed lignin. AB - The aim of this study is to explore the reaction mediums and conditions for producing high yield of valuable monomers from concentrated sulfuric acid hydrolyzed lignin. The solvent, temperature and time effects on the hydrogenolysis of hydrolyzed lignin were investigated under the catalysis of Pd/C and CrCl3. Supercritical methanol exhibits the best depolymerization performance, because of its unique diffusion, dissolution and acid-base properties. Afterwards, the influence of reaction temperature and time on depolymerization, repolymerization and coking during hydrogenolysis was examined in methanol. The high temperature is found to favor the depolymerization, with the beta-O-4 linkages cleaved significantly. However, the repolymerization is promoted simultaneously, and a high amount of beta-beta groups form. These reactions are in constant competition with each other and the repolymerization is preferred at excessive high temperature, producing bulk char residues, that is coking. This study will provide a beneficial reference for the maximization of lignin waste valorization. PMID- 27686726 TI - Cannabidiol: a potential treatment for post Ebola syndrome? AB - Patients recovered from Ebola virus infection may experience short- and long-term physical, neuropsychological and social sequelae, including arthralgia, musculoskeletal pain, ophthalmic inflammation, auditory problems, fatigue, confusion, insomnia, short-term memory impairment, anxiety, depression and anorexia, all lasting from two weeks to more than two years. Currently there are no treatments for post Ebola sequelae. We hypothesize that cannabidiol (CBD) may attenuate some of these post Ebola sequelae, several of which have been postulated to result from inflammation and/or an autoimmune response. CBD has anti-inflammatory actions in various animal models. Clinical studies have shown that oral administration of CBD, compared to placebo, significantly reduces anxiety, has antinociceptive and anticonvulsant actions, and may be therapeutic for insomnia. Overall, CBD has a number of pharmacological effects that may significantly improve the mental and somatic health of patients suffering from post Ebola sequelae. In humans, CBD, at therapeutic doses, does not: 1) elicit dependence or tolerance; 2) significantly alter heart rate or blood pressure; 3) affect gastrointestinal transit; 4) produce significant cognitive or psychomotor impairments. Mild sedation and nausea are the most commonly reported adverse effects associated with CBD.CBD, based on its pharmacological effects and favorable safety profile, should be considered as a treatment for individuals with post Ebola sequelae. PMID- 27686727 TI - Implementing a care bundle approach reduces ventilator-associated pneumonia and delays ventilator-associated tracheobronchitis in children: differences according to endotracheal or tracheostomy devices. AB - OBJECTIVE: To reduce ventilator-associated infections (VARI) and improve outcomes for children. METHODS: This prospective interventional cohort study was conducted in a paediatric intensive care unit (PICU) over three periods: pre-intervention, early post-intervention, and late post-intervention. These children were on mechanical ventilation (MV) for >=48h. RESULTS: Overall, 312 children (11.9% of whom underwent tracheostomy) and 6187 ventilator-days were assessed. There was a significant reduction in ventilator-associated pneumonia (VAP) among tracheostomized patients (8.16, 3.27, and 0.65 per 1000 tracheostomy ventilation days before the intervention, after the general bundle implementation, and after the tracheostomy intervention, respectively). The median time from onset of MV to diagnosis of ventilator-associated tracheobronchitis (VAT) increased from 5.5 to 48 days in the late post-intervention period (p=0.004), and was associated with a significant increase in median 28-day ventilator-free days and PICU-free days. Tracheostomy (odds ratio 7.44) and prolonged MV (odds ratio 2.75) were independent variables significantly associated with VARI. A trend towards a reduction in PICU mortality was observed, from 28.4% to 16.6% (relative risk 0.58). CONCLUSIONS: The implementation of a care bundle to prevent VARI in children had a different impact on VAP and VAT, diminishing VAP rates and delaying VAT onset, resulting in reduced healthcare resource use. Tracheostomized children were at increased risk of VARI, but preventive measures had a greater impact on them. PMID- 27686728 TI - Quantitative intrahepatic HBV cccDNA correlates with histological liver inflammation in chronic hepatitis B virus infection. AB - BACKGROUND: The aim of this study was to determine the role of baseline hepatitis B virus (HBV) forming covalently closed circular DNA (HBV cccDNA) in liver inflammation in patients infected with HBV with serum alanine aminotransferase (ALT) levels under two times the upper limit of normal (2*ULN). METHODS: After liver biopsy and serum virological and biochemical marker screening, patients diagnosed with chronic HBV infection with serum ALT levels under 2*ULN and histological liver inflammation of less than grade G2 were prospectively recruited into this study. Recruitment took place between March 2009 and November 2010 at the Center of Infectious Disease, Sichuan University. Patient virological and biochemical markers, as well as markers of liver inflammation, were monitored. RESULTS: A total of 102 patients were recruited and 68 met the inclusion criteria; the median follow-up was 4.1 years (range 3.9-5.2 years). During follow-up, 41 patients (60.3%) exhibited signs of inflammation. Baseline HBV cccDNA >1 copy/cell (odds ratio 9.43, p=0.049) and liver inflammation grade >=G1 (odds ratio 5.77, p=0.046) were both independent predictors of liver inflammation. CONCLUSIONS: A higher baseline intrahepatic HBV cccDNA level may increase the risk of liver inflammation. Further investigations will be required to validate HBV cccDNA as an intrahepatic virological marker of patients who require extended outpatient management. PMID- 27686729 TI - Molecular mechanisms underlying fibrosis and elastin destruction in childhood interstitial lung diseases. AB - OBJECTIVE: This study aimed to evaluate fibrosis and elastin destruction in childhood interstitial lung disease (chILD) patients. METHODS: Sixty patients and twenty healthy children were recruited. On admission, evaluation of chILD severity was made using Fan chILD score. Participants provided urine and blood samples. Plasma levels of transforming growth factor (TGF)-beta1, connective tissue growth factor (CCN2), soluble factor related apoptosis (sFas) and long non coding RNAs and urinary levels of desmosine/urinary creatinine (UDes/UCr) were measured. RESULTS: In patients, clinical findings were crackles (100.00%), tachypnea (65.00%), cardiomegaly (45.00%), digital clubbing (43.30%), cough (33.00%), cyanosis (26.70%), hepatomegaly (28.30%) and wheezes (23.30%). Categorizing of the patients with Fan chILD clinical score revealed that most patients 33.30% scored (3, symptomatic with abnormal saturation/cyanosis during exercise) then 28.30% scored (5, symptomatic with clinical and echocardiographic features of pulmonary hypertension), 18.30% scored (2, symptomatic with normal room air saturations), 15.00% scored (1, asymptomatic) and 5.00% scored (4, symptomatic with abnormal room air saturation/cyanosis at rest). TGF-beta1, CCN2, sFas, lncrRNA-2700086A05Rik relative gene expression and UDes/UCr levels were higher in patients than controls (P=0.002, P=0.001, P=0.001, P=0.001, P=0.001, respectively). In patients, significant positive correlations were found between TGF-beta1 and CCN2, sFas, UDes/UCr; between CCN2 and both sFas and UDes/UCr; between UDes/UCr and sFas. Morbidity and mortality rates were 46.70% and 10.00%, respectively. CONCLUSION: Markers of fibrosis (TGF-beta1, sFas, CCN2) and elastin destruction (UDes/UCr) were increased in chILD especially in patients with long disease duration. So blockage of their pathways signals may offer novel therapeutic targets. PMID- 27686730 TI - Publish (in English) or perish: The effect on citation rate of using languages other than English in scientific publications. AB - There is a tendency for non-native English scientists to publish exclusively in English, assuming that this will make their articles more visible and cited. We tested this hypothesis by comparing the effect of language on the number of citations of articles published in six natural sciences journals from five countries that publish papers in either English or other languages. We analyzed the effect of language (English vs non-English), paper length, and year of publication on the number of citations. The articles published in English have a higher number of citations than those published in other languages, when the effect of journal, year of publication, and paper length are statistically controlled. This may result because English articles are accessible to a larger audience, but other factors need to be explored. Universities and scientific institutions should be aware of this situation and improve the teaching of English, especially in the natural sciences. PMID- 27686731 TI - Rehabilitating mussel beds in Coffee Bay, South Africa: Towards fostering cooperative small-scale fisheries governance and enabling community upliftment. AB - Along the coast of South Africa, marine resources play a significant role in supporting livelihoods and contributing to food security in impoverished rural communities. Post-apartheid fisheries laws and policies have begun to address traditional fishing rights and development needs, and new management arrangements are being implemented. One such initiative has been the Mussel Rehabilitation Project in Coffee Bay, which piloted a resource rehabilitation technique at several over-exploited fishing sites. Mussel stocks in these exploited areas had dropped to under 1 % mussel cover, and during the project period, stocks increased to >80 % cover, supporting a sustainable harvest well above national daily bag limits. This stock enhancement was achieved only after the project had started to address social challenges such as the lack of local management institutions and the need to enhance food security. The project embarked on training and institution-building; it formed a robust community mussel management committee; and developed a local resource management plan, facilitating increased community participation in the day-to-day management of the resource. The project also saw the initiation of various ancillary projects aimed at improving food security and stimulating the local economy and hence alleviating pressure on the marine resources. Here we review this 10-year project's outcomes, and present lessons for small-scale fisheries governance in South Africa and internationally. We show, through empirical experience, that balancing stock rebuilding needs in a context of widespread poverty and dependency on natural resources by a local fisher community can only be addressed through an integrated approach to development. Participation of resource users and a thorough understanding of the local context are imperative to negotiating appropriate small-scale fisheries governance approaches. We recommend that the implementation of South Africa's newly minted Small-Scale Fisheries Policy should begin with bottom-up, demonstrative resource management measures such as mussel rehabilitation. This type of initiative can deliver short-term food security benefits and foster social learning towards sustainable and cooperative fisheries governance.

AB - Hb Zurich-Albisrieden [HBA2: c.178G > C; alpha59(E8)Gly->Arg (alpha2)] is a rare nondeletional alpha-thalassemia (alpha-thal) that results from a nucleotide substitution at codon 59 of the alpha2-globin gene. In this report, we present a fetus with cardiomegaly, enlarged placenta and increased middle cerebral artery peak systolic velocity (MCA-PSV) at 25 weeks' gestation. Fetal blood sampling revealed the severe anemia [hemoglobin (Hb) level being 5.5 g/dL] and Hb H (beta4) disease-like hematological findings with Hb Bart's (gamma4) level of 30.7%. Molecular analysis of the family found that the father was an Hb Zurich Albisrieden carrier, the mother heterozygous for the - -SEA alpha0-thal deletion, and the fetus was a compound heterozygote for Hb Zurich-Albisrieden and the - SEA alpha0-thal deletion. Therefore, this was a rare case of Hb Bart's hydrops fetalis associated with Hb Zurich Albisrieden. PMID- 27686734 TI - Single-dose acarbose decreased glucose-dependent insulinotropic peptide and glucagon levels in Chinese patients with newly diagnosed type 2 diabetes mellitus after a mixed meal. AB - BACKGROUND: Acarbose slows down the intestinal absorption of carbohydrates, but its effects on the secretion of incretins are still poorly known. This study aimed to examine the effects of single-dose acarbose on the secretion of incretins in patients with newly diagnosed type 2 diabetes mellitus (T2DM). METHODS: In this pilot study, twenty-three patients diagnosed with T2DM were randomly assigned to the oral glucose tolerance test (OGTT) group (n = 11) and the mixed meal test (MMT) group (n = 12). Fourteen subjects with normal OGTT were included as controls. Plasma glucose, insulin, glucagon, glucagon-like peptide-1 (GLP-1), and glucose-dependent insulinotropic peptide (GIP) were measured at 0 (fasting), 15, 30, 60, 90, and 120 min after nutrient load. A week later, controls underwent MMT, the OGTT group underwent OGTT receiving 100 mg acarbose, and the MMT group underwent MMT receiving 100 mg acarbose. The same blood markers were measured again. RESULTS: No significant difference was observed in the OGTT group before and after administering acarbose. In the MMT group, postprandial levels of glucose (P < 0.01), insulin (P < 0.01), glucagon at 15 min (P < 0.05), glucagon area under the curve (AUC) (P < 0.05), GIP levels at 30 min (P < 0.05), and GIP AUC (P < 0.05) were decreased after receiving acarbose with a mixed meal, but GLP-1 levels and GLP-1 AUC did not change. CONCLUSIONS: Single-dose acarbose could reduce the secretion of GIP and glucagon after a mixed meal in patients with newly diagnosed T2DM. The influence of acarbose on incretin levels could be related to the types of carbohydrate being consumed. TRIAL REGISTRATION: This study was registered with the Chinese Clinical Trial Registry (Registration Number: ChiCTR-TRC-14004260 , Date of Registration: 2014-01-19). PMID- 27686732 TI - Long non-coding RNAs: potential new biomarkers for predicting tumor invasion and metastasis. AB - Long non-coding RNAs (lncRNAs) play important roles in malignant neoplasia. Indeed, many hallmarks of cancer define that the malignant phenotype of tumor cells are controlled by lncRNAs. Despite a growing number of studies highlighting their importance in cancer, there has been no systematic review of metastasis associated lncRNAs in various cancer types. Accordingly, we focus on the key metastasis-related lncRNAs and outline their expression status in cancer tissues by reviewing the previous stuides, in order to summarize the nowadays research achivements for lncRNAs related to cancer metastasis. Medline, EMBASE, as well as PubMed databases were applied to study lncRNAs which were tightly associated with tumor invasion and metastasis. Up to now, a substantial number of lncRNAs have been found to have important biological functions. In this review, according to their various features in cancer, lncRNAs were roughly divided into three categories: promoting tumor invasion and metastasis, negative regulation of tumor metastasis and with dual regulatory roles. The present studies may establish the foundation for both further research on the mechanisms of cancer progression and future lncRNA-based clinical applications.

PMID- 27686735 TI - Assessing the level of evidence on transfer and transition in young people with chronic conditions: protocol of a scoping review. AB - BACKGROUND: Life-long specialized care is of the utmost importance to safeguard longevity as well as the quality of life in children diagnosed with a chronic condition (CC). Provision of life-long care, however, infers transfers to different settings in line with person's development status. Young people with CC (10-25 years) will transfer care from a pediatric towards an adult-oriented care setting. As a transfer of care is associated with a change of care context, healthcare team, responsibilities, expectations, and roles, patients need to be prepared for this alteration. One type of preparatory intervention is the provision of transitional care. Transition prepares adolescents for the responsibilities associated with adult care and age through support, education, skills demonstration, and guidance. The past decades, increasing attention has been paid towards the concept of transfer and transition, both in clinical practice and research. Numerous consensus papers have been established, emphasizing the need for the establishment of a transition program for young patients with CC. To date, it remains, however, unclear what the overall level of evidence is on transfer and transition in this population. This scoping review aims to analyze and determine the level of evidence of published literature on transfer and transition of young people diagnosed with CC. METHOD: MEDLINE, CINAHL, Scopus, and Web of Science databases will be searched for relevant publications. Any publication in English, Spanish, German, or French, related to transfer and/or transition in young people with CC will be included. A three staged approach will identify relevant papers, comprising systematic database searches, application of snowball method, and citation searching. Study selection will be performed through screening of titles/abstracts followed by a full-text assessment using a standardized selection form. Data extraction will be performed by two reviewers independently using a pilot-tested, standardized form. Descriptive statistics and content analysis will be applied to present the results. Bibliometric visualization techniques will be performed with VOS viewer(r). DISCUSSION: Our review will map the overall level of evidence of published literature on transfer and transition in young people with CC. It will provide guidance for future research initiatives, clinical practice, and policy makers. PMID- 27686737 TI - New revised simple models for interactive wild and sterile mosquito populations and their dynamics. AB - Based on previous research, we formulate revised, new, simple models for interactive wild and sterile mosquitoes which are better approximations to real biological situations but mathematically more tractable. We give basic investigations of the dynamical features of these simple models such as the existence of equilibria and their stability. Numerical examples to demonstrate our findings and brief discussions are also provided. PMID- 27686738 TI - Variation of anthocyanins and other major phenolic compounds throughout the ripening of four Portuguese blueberry (Vaccinium corymbosum L) cultivars. AB - Blueberries are widely recognised as one of the richest sources of bioactive compounds, among which are anthocyanins, though the ripeness of berries has been reported as affecting the phytochemical composition of fruits. Therefore, the present work aimed to evaluate the variation of anthocyanins, and other major phenolics, throughout five ripening stages in four blueberry cultivars. The results showed that the antioxidant capacity and anthocyanin content increased during ripening, reaching the highest values when the blueberries are collected from bunches comprised of 75% ripe blueberries. Antagonistically, the amount of phenolic acid decreases, while the quercetin-3-glucoside levels remain stable. Furthermore, Goldtraube blueberries appear to possess, systematically, higher amounts of phenolic compounds than the other cultivars studied. Thus, when seeking the highest yield of anthocyanins, the preferred harvest should occur in bunches that contain ca 75% of ripe blueberries and, considering the cultivars assayed, the Goldtraube cultivar appears to be the richest in phenolic compounds.

PMID- 27686740 TI - Efficacy of poly (ADP-ribose) polymerase inhibitor olaparib against head and neck cancer cells: Predictions of drug sensitivity based on PAR-p53-NF-kappaB interactions. AB - Poly (ADP-ribose) polymerase (PARP) is a key molecule in the DNA damage response (DDR), which is a major target of both chemotherapies and radiotherapies. PARP inhibitors therefore comprise a promising class of anticancer therapeutics. In this study, we evaluated the efficacy of the PARP inhibitor olaparib, and also sought to identify the mechanism and predictive marker associated with olaparib sensitivity in head and neck cancer (HNC) cells. A total of 15 HNC cell lines, including AMC HNC cells, were tested. AMC-HN3 and HN4 exhibited stronger responses to olaparib. Among cisplatin-resistant cell lines, only AMC HN9-cisR cells were significantly suppressed by olaparib. We found that basal poly (ADP ribose) (PAR) levels, but not PARP-1 levels, correlated with olaparib sensitivity. AMC-HN3 and HN4 cells exhibited higher basal levels of NF-kappaB that decreased significantly after olaparib treatment. In contrast, apoptotic proteins were intrinsically expressed in AMC-HN9-cisR cells. As interference with p53 expression led to NF-kappaB reactivation, we concluded that elevated basal PAR and NF-kappaB levels are predictive of olaparib responsiveness in HNC cells; in addition, olaparib inhibits HNC cells via PAR-p53-NF-kappaB interactions. PMID- 27686741 TI - Maternal high-fat diet during lactation impairs thermogenic function of brown adipose tissue in offspring mice. AB - Maternal obesity and high-fat diet (HFD) predisposes offspring to obesity and metabolic diseases. Due to uncoupling, brown adipose tissue (BAT) dissipates energy via heat generation, mitigating obesity and diabetes. The lactation stage is a manageable period for improving the health of offspring of obese mothers, but the impact of maternal HFD during lactation on offspring BAT function is unknown. To determine, female mice were fed either a control or HFD during lactation. At weaning, HFD offspring gained more body weight and had greater body fat mass compared to the control, and these differences maintained into adulthood, which correlated with glucose intolerance and insulin resistance in HFD offspring. Adaptive thermogenesis of BAT was impaired in HFD offspring at weaning. In adulthood, HFD offspring BAT had lower Ucp1 expression and thermogenic activity. Mechanistically, maternal HFD feeding during lactation elevated peripheral serotonin, which decreased the sensitivity of BAT to sympathetic beta3-adrenergic signaling. Importantly, early postnatal metformin administration decreased serotonin concentration and ameliorated the impairment of offspring BAT due to maternal HFD. Our data suggest that attenuation of BAT thermogenic function may be a key mechanism linking maternal HFD during lactation to persisted metabolic disorder in the offspring.

AB - INTRODUCTION: Chronic insufficiency of lower extremity venous valves represents a frequent structural disorder of the vascular system being responsible for a substantial global disease load. While in the field of superficial valve insufficiency surgical as well as endoluminal interventions represent good therapeutic options with high rates of complete remission of symptoms, only limited options exist in the field of deep venous reflux today. Bioengineered, autologous cell-based, endothelialized valve constructs may open up new therapeutic options in these patients, potentially offering novel treatment options in cases with severe insufficiency of deep venous segments in the future. Areas covered: This review summarizes previous reports focusing on venous valve replacement and bioengineering, also including first preclinical in vivo studies and first clinical trials in patients. In particular, the aspects of current technical and medical limitations of venous valve bioengineering approaches preventing clinical translation and potential solutions by upcoming technologies will be discussed as part of this review. Expert commentary: Bioengineered replacement valves may open up novel options in the treatment of venous valve disease in defined patient groups in the future. However, preventing thromboembolic complications will remain the bottle-neck for clinical translation of the technologies involved. PMID- 27686742 TI - Bithionol blocks pathogenicity of bacterial toxins, ricin, and Zika virus. AB - Diverse pathogenic agents often utilize overlapping host networks, and hub proteins within these networks represent attractive targets for broad-spectrum drugs. Using bacterial toxins, we describe a new approach for discovering broad spectrum therapies capable of inhibiting host proteins that mediate multiple pathogenic pathways. This approach can be widely used, as it combines genetic based target identification with cell survival-based and protein function-based multiplex drug screens, and concurrently discovers therapeutic compounds and their protein targets. Using B-lymphoblastoid cells derived from the HapMap Project cohort of persons of African, European, and Asian ancestry we identified host caspases as hub proteins that mediate the lethality of multiple pathogenic agents. We discovered that an approved drug, Bithionol, inhibits host caspases and also reduces the detrimental effects of anthrax lethal toxin, diphtheria toxin, cholera toxin, Pseudomonas aeruginosa exotoxin A, Botulinum neurotoxin, ricin, and Zika virus. Our study reveals the practicality of identifying host proteins that mediate multiple disease pathways and discovering broad-spectrum therapies that target these hub proteins. PMID- 27686744 TI - Stille coupling via C-N bond cleavage. AB - Cross-coupling is a fundamental reaction in the synthesis of functional molecules, and has been widely applied, for example, to phenols, anilines, alcohols, amines and their derivatives. Here we report the Ni-catalysed Stille cross-coupling reaction of quaternary ammonium salts via C-N bond cleavage. Aryl/alkyl-trimethylammonium salts [Ar/R-NMe3]+ react smoothly with arylstannanes in 1:1 molar ratio in the presence of a catalytic amount of commercially available Ni(cod)2 and imidazole ligand together with 3.0 equivalents of CsF, affording the corresponding biaryl with broad functional group compatibility. The reaction pathway, including C-N bond cleavage step, is proposed based on the experimental and computational findings, as well as isolation and single-crystal X-ray diffraction analysis of Ni-containing intermediates. This reaction should be widely applicable for transformation of amines/quaternary ammonium salts into multi-aromatics.

AB - The fabrication of all polymer optical waveguides, based on a highly fluorescent conjugated polymer (CP) poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT) and a mechanically flexible and biodegradable polymer, cellulose acetate (CA), is reported. The replication by hot embossing of patterned surfaces in CA substrates, onto which high quality F8BT films can be easily processed by spin coating, is exploited to produce an entirely plastic device that exhibits low optical loss and low threshold for amplified spontaneous emission (ASE). As a result, highly transparent and flexible waveguides are obtained, with excellent optical properties that remain unaltered after bending, allowing them to be adapted in various flexible photonic devices. PMID- 27686746 TI - In low protein diets, microRNA-19b regulates urea synthesis by targeting SIRT5. AB - Ammonia detoxification, which takes place via the hepatic urea cycle, is essential for nitrogen homeostasis and physiological well-being. It has been reported that a reduction in dietary protein reduces urea nitrogen. MicroRNAs (miRNAs) are major regulatory non-coding RNAs that have significant effects on several metabolic pathways; however, little is known on whether miRNAs regulate hepatic urea synthesis. The objective of this study was to assess the miRNA expression profile in a low protein diet and identify miRNAs involved in the regulation of the hepatic urea cycle using a porcine model. Weaned 28-days old piglets were fed a corn-soybean normal protein diet (NP) or a corn-soybean low protein diet (LP) for 30 d. Hepatic and blood samples were collected, and the miRNA expression profile was assessed by sequencing and qRT-PCR. Furthermore, we evaluated the possible role of miR-19b in urea synthesis regulation. There were 25 differentially expressed miRNAs between the NP and LP groups. Six of these miRNAs were predicted to be involved in urea cycle metabolism. MiR-19b negatively regulated urea synthesis by targeting SIRT5, which is a positive regulator of CPS1, the rate limiting enzyme in the urea cycle. Our study presented a novel explanation of ureagenesis regulation by miRNAs. PMID- 27686747 TI - Neutrophil-to-lymphocyte ratio is a reliable marker of treatment response in rheumatoid arthritis patients during tocilizumab therapy. AB - OBJECTIVE: To investigate the reliable markers reflecting treatment response better than the traditional inflammatory indices in patients with rheumatoid arthritis (RA) receiving tocilizumab therapy. METHODS: A total of 58 RA patients treated with tocilizumab for more than six months from January 2013 to December 2014 were initially included. Flares were defined as events that required steroid dose escalation, intra-articular steroid injections, or switching tocilizumab to other biologic agents. The clinical and laboratory data were retrospectively collected from electronic medical records. RESULTS: Of the 52 patients except for six patients who were excluded, 16 experienced flares, and 36 were stable during tocilizumab therapy. The C-reactive protein (CRP) level did not significantly differ between a stable state before flares and at flares. Compared with those at the preflare time point, erythrocyte sedimentation rate (ESR), and neutrophil to lymphocyte ratio (NLR) were significantly higher at flares; however, ESR levels (n = 9) were within the normal limit or decreased (n = 4) at flares. Interestingly, NLR increased at flares in all but one patient in the flare group. CONCLUSION: NLR is a more reliable marker than ESR or CRP for evaluating the disease activity in patients with RA during tocilizumab therapy. PMID- 27686748 TI - Accuracy Improvement for Predicting Parkinson's Disease Progression. AB - Parkinson's disease (PD) is a member of a larger group of neuromotor diseases marked by the progressive death of dopamineproducing cells in the brain. Providing computational tools for Parkinson disease using a set of data that contains medical information is very desirable for alleviating the symptoms that can help the amount of people who want to discover the risk of disease at an early stage. This paper proposes a new hybrid intelligent system for the prediction of PD progression using noise removal, clustering and prediction methods. Principal Component Analysis (PCA) and Expectation Maximization (EM) are respectively employed to address the multi-collinearity problems in the experimental datasets and clustering the data. We then apply Adaptive Neuro-Fuzzy Inference System (ANFIS) and Support Vector Regression (SVR) for prediction of PD progression. Experimental results on public Parkinson's datasets show that the proposed method remarkably improves the accuracy of prediction of PD progression. The hybrid intelligent system can assist medical practitioners in the healthcare practice for early detection of Parkinson disease. PMID- 27686749 TI - Mepacrine as successful monotherapy for refractory Jessner-Kanof disease: still an important drug in the dermatologic armamentarium. AB - INTRODUCTION: Jessner-Kanof disease (JKD), a lymphocytic infiltration of the skin, can be difficult to treat. Mepacrine (quinacrine), an anti-malarial less available in Belgium, may be beneficial. PATIENTS AND METHODS: Two female patients with biopsy-proven and therapy-resistant JKD, not responding to topical and systemic corticosteroids, (hydroxy-)chloroquine and/or dapsone, were treated with mepacrine 100 mg daily. RESULTS: In both patients an amelioration was observed during the first month of treatment, and clinical remission was obtained by the fourth month, without any side-effects. In both cases, the dose could be tapered to three times weekly. DISCUSSION: JKD is strongly related to lupus erythematosus (tumidus), and although spontaneous remissions may occur, it is notoriously difficult to treat. Mepacrine may be initiated as an add-on therapy to (hydroxy-)chloroquine, but also as monotherapy. A dose of 100 mg a day, tapered to weekly doses once remission is obtained, seems feasible. Except for (mild) yellow skin discoloration, the drug has few side-effects, and offers the advantage of not displaying retinal toxicity. CONCLUSION: Mepacrine is still a useful and safe drug for treating cutaneous lupus erythematosus and related skin conditions, such as refractory JKD in particular. Its future availability, also in Belgium, is therefore important. PMID- 27686750 TI - Caffeoylquinic acids from antiplasmodial active extract of Xanthium cavanillesii fruits and their molecular modelling studies. AB - The antiplasmodial active extract of Xanthium cavanillesii contains 3,4 dicaffeoyl quinic acid (3,4-DCQA), 3,5-dicaffeoyl quinic acid (3,5-DCQA) and 1,3,5-tricaffeoyl quinic acid (1,3,5-TCQA). These results inspired us to investigate the interaction of these molecules with a promising validated target of Plasmodium, PfATP6 orthologue of mammalian Ca+2-ATPase. Models of this receptor were obtained through comparative modelling. Afterwards, molecular docking studies were used to identify possible interaction modes of these caffeoyl quinic derivatives on the binding site. The 1,3,5-TCQA had the best energy, but all of these had better energy than thapsigargin, a non-competitive inhibitor of the sarco/endoplasmatic reticulum Ca+2-ATPase (SERCA). PMID- 27686752 TI - Patient Satisfaction with Pharmacist-Led Collaborative Follow-Up Care in an Ambulatory Rheumatology Clinic. AB - OBJECTIVES: Patient satisfaction is known to increase with pharmacist intervention in general outpatient clinics and with nurse-led care in rheumatology clinics. The aim of the present study was to describe and compare patient satisfaction with two different types of care: a pharmacist physician collaborative model and a traditional physician model in a rheumatology clinic setting. METHODS: A cross-sectional survey of inflammatory arthritis patients seen during a follow-up visit in Edmonton, Alberta, Canada, was conducted over a ten-week period. Patient satisfaction was measured using a modified version of the validated Leeds Satisfaction Questionnaire, which uses a five-point Likert scale to measure six dimensions of satisfaction, and compared between the collaborative care and traditional physician models. RESULTS: A total of 62 patients completed the questionnaire (21 collaborative care and 41 traditional physician model). The average age of respondents was 52 years and the majority were female. The mean score for satisfaction across the six dimensions was 4.56 in the collaborative care group and 4.30 in the traditional physician group (p = 0.02). Patient satisfaction in the collaborative care group was consistently higher across all dimensions. No difference was noted between participants seen for the first time compared with those seen two or more times by the pharmacist. CONCLUSIONS: A collaborative care model can exceed the already high expectations for care of patients with inflammatory arthritis. Our findings support the role of pharmacists using a collaborative care approach to care for patients in rheumatology clinics. PMID- 27686753 TI - Overlapping Electronic States with Nearly Parallel Transition Dipole Moments in Reduced Anionic Flavin Can Distort Photobiological Dynamics. AB - Chromophoric biomolecules are exploited as reporters of a diverse set of phenomena, acting as internal distance monitors, environment and redox sensors, and endogenous imaging probes. The extent to which they can be exploited is dependent on an accurate knowledge of their fundamental electronic properties. Arguably of greatest importance is a precise knowledge of the direction(s) of the absorption transition dipole moment(s) (TDMs) in the molecular frame of reference. Such is the case for flavins, fluorescent redox cofactors utilized for ground- and excited-state redox and photochemical processes. The directions of the TDMs in oxidized and semiquinone flavins were characterized decades ago, and the details of charge redistribution in these forms have also been studied by Stark spectroscopy. The electronic structure of the fully reduced hydroquinone anionic state, FlH-, however, has been the subject of unfounded assumptions and estimates about the number and direction of TDMs in FlH-, as well the electronic structure changes that occur upon light absorption. Here we have used Stark spectroscopy to measure the magnitude and direction of charge redistribution in FlH- upon optical excitation. These data were analyzed using TD-DFT calculations. The results show unequivocally that not one but two nearly orientation-degenerate electronic transitions are required to explain the 340-500 nm absorption spectral range, demolishing the commonly held assumption of a single transition. The difference dipole moments for these states show that electron density shifts toward the xylene ring for both transitions. These measurements force a reappraisal of previous studies that have used erroneous assumptions and unsubstantiated estimates of these quantities. The results put future optical studies of reduced flavins/flavoproteins on a firm photophysical footing. PMID- 27686751 TI - Characteristics of Qualitative Descriptive Studies: A Systematic Review. AB - Qualitative description (QD) is a term that is widely used to describe qualitative studies of health care and nursing-related phenomena. However, limited discussions regarding QD are found in the existing literature. In this systematic review, we identified characteristics of methods and findings reported in research articles published in 2014 whose authors identified the work as QD. After searching and screening, data were extracted from the sample of 55 QD articles and examined to characterize research objectives, design justification, theoretical/philosophical frameworks, sampling and sample size, data collection and sources, data analysis, and presentation of findings. In this review, three primary findings were identified. First, although there were some inconsistencies, most articles included characteristics consistent with the limited available QD definitions and descriptions. Next, flexibility or variability of methods was common and effective for obtaining rich data and achieving understanding of a phenomenon. Finally, justification for how a QD approach was chosen and why it would be an appropriate fit for a particular study was limited in the sample and, therefore, in need of increased attention. Based on these findings, recommendations include encouragement to researchers to provide as many details as possible regarding the methods of their QD studies so that readers can determine whether the methods used were reasonable and effective in producing useful findings.

AB - PURPOSE: Limited data exist that support the reproducibility of cervical auscultation (CA) use in children. This study aimed to determine the reliability of CA in detecting oropharyngeal aspiration (OPA) in children within a controlled environment. METHOD: This observational study included eight speech-language pathologists who rated clips of 40 normal and 40 OPA swallowing sounds on two separate occasions (i.e.160 sound clips rated by each speech-language pathologist) to comprise a total of 1280 swallow clips rated. Swallowing sound clips were collected from (1) a volunteer sample of 20 healthy children from the general community (mean 16.2 +/- 10.7 months; 65% female); (2) a referred sample of 19 children with demonstrated OPA (mean 22.8 +/- 25.5 months; 36.8% female), as determined on videofluoroscopic swallow studies (VFSS) using the Penetration Aspiration Scale (PAS) (>=6 score). RESULT: Inter-rater reliability was very good (kappa =0.81, 95%CI 0.79-0.84). Intra-rater reliability for each rater was good to very good (kappa range 0.72-0.98). Overall sensitivity was 93.9% (95%CI 91.8 95.6) and specificity was 94.5% (95%CI 92.5-96.2). High reliability values were found for the detection of OPA versus normal swallows using CA alone. CONCLUSION: Future research should investigate the use of CA in a variety of clinical settings with less environmental control before CA can be advocated for use in routine clinical practice. PMID- 27686758 TI - [Discussion of HIV control and prevention strategies]. AB - Expansion of HIV testing and ART treatment are core strategies for achieving the ambitious global goal of ending the HIV epidemic by the end of 2030, and achieving the "90-90-90" target by 2020. In China, great progress in HIV control and prevention has been made; however, there is room to enhance the effectiveness of HIV-related strategies. In addition, some implemented strategies have not achieved their expected output. To confront the challenge of sexual transmission of HIV, which is the main route of transmission in China, more targeted HIV prevention strategies that lead to their expected outcomes are essential. It is important to strengthen existing strategies that have been proved effective. However, it is also critical to create innovative strategies, and there are five approaches to achieve this. First, a holistic perspective should be adopted, to better understand the current situation and problems. This means intervention strategies should give serious consideration of how to meet the sociocultural needs of target populations rather than merely carry out behavioral interventions. Second, community-based HIV prevention settings should have more important roles in providing HIV-related health care services. Moreover, to improve the effectiveness of these strategies, a problem-led working style should be integrated into HIV prevention measures overall. Third, thoroughly analyzing characteristics of the current HIV epidemic using more evidence-based considerations must be undertaken, to better control HIV sexual transmission. Fourth, continued improvement of AIDS prevention and control mechanisms is needed, to ensure their sustainable development. Last, it is necessary to involve more NGOs in HIV prevention work by strengthening their management and working capacities to provide HIV-related services. Also needed is further improvement in both technical and management capacities, so as to build a stable basis for effective response.

AB - Objective: To introduce the development strategy of " Internet Plus" AIDS prevention services and its implementation results from 2010 to 2015 in Guangzhou, China. Methods: A gay men's health column was created for an active website aimed at men who have sex with men(MSM), in collaboration with local community organizations and the Guangzhou CDC. We designed intervention tools(including scenario-based applications and HIV risk self-assessment systems)and an online HIV testing service platform, integrated with applied psychology and behavioral theory as well as the " Internet Plus" concept, to intervene in HIV infection risk factors among MSM. Data of clients who accessed the " Internet Plus" AIDS services from 2010 to 2015 were used to evaluate service operation. Six-year consecutive surveys, conducted between April and July of each service year, were collected using a national AIDS sentinel surveillance questionnaire. For each year of surveillance, information on HIV prevalence, HIV interventions received during the past year, unprotected anal intercourse in the past 6 months, and HIV testing in the past year were compared using the chi squared(chi2)test, to roughly reflect the effect of"Internet Plus" AIDS prevention services. Results: As of 31 December 2015, a total of 34 395 MSM had received " Internet Plus" services and HIV testing. The number of MSM tested increased from 2 338 in 2010 to 8 054 in 2015. From 2010 to 2015, newly identified HIV cases in each year were 59, 166, 312, 283, 291, and 270, which accounted for 25.0%, 32.8%, 38.8%, 35.1%, 30.5%, and 23.2% of MSM HIV cases of Guangzhou, respectively. Sentinel surveillance data showed that during the study period, 3 047 MSM were investigated, with 405, 400, 401, 633, 608, and 600 each year, respectively. The proportion of participants who had received any HIV intervention during the past year was 74.3%(301), 70.8%(283), 83.3%(334), 85.0%(538), 69.1%(420), and 83.8%(503)each year, respectively(trend chi2=6.53, P=0.011). HIV testing done during the past year accounted for 44.0%(178), 44.3%(177), 49.4%(198), 53.4%(338), 56.1%(341), and 60.2%(361)each year, respectively(trend chi2=40.83, P<0.001). Unprotected anal intercourse in the past 6 months accounted for 59.3%(240), 62.0%(248), 56.6%(227), 57.0%(361), 48.4%(294), and 43.7%(262)each year, respectively(trend chi2=42.21, P<0.001). Conclusion: The"Internet Plus"AIDS prevention services in this study represent a manner to enhance traditional HIV prevention strategies. We found these services to be effective in implementation of the national AIDS control and prevention strategy, especially for the expansion of intervention, testing, and case identification among high-risk populations. PMID- 27686762 TI - [Influence of sociocultural factors on HIV transmission among men who have sex with men: a qualitative study]. AB - Objective: To understand how social and cultural factors influence sexual perceptions, sexual practices, and HIV transmission among men who have sex with men at selected sites in China. Methods: Qualitative methodology was used and face to face, semi-structured, in-depth interviews conducted from April 2013 to October 2015 in Sichuan, Jiangxi, Henan, Heilongjiang provinces and Chongqing municipality of China. Results: A total of 184 men who have sex with men participated in the interviews. Forty-eight originated from Henan Province, and 12, 50, 47, and 27 from Jiangxi, Heilongjiang, Sichuan provinces and Chongqing municipality, respectively. A total of 122 participants(66.3%)were under 30 years of age, 111 were college graduates(61.3%), 140 were unmarried(76.5%), and 74 were HIV positive(40.2%). Among interviewees, 6%(11 MSM)were employed at nongovernmental organizations. The main findings revealed that: Owing to sociocultural influences and social norms, most homosexual men concealed their sexual orientation and married females so as to fulfill their family obligation; this may encourage HIV transmission from a high-risk population to the general population; the main features of male homosexual behaviors, as well as those of the associated community and subculture, included hedonism, less concern about health, drug abuse, encouraging of high risk behaviors among men who have sex with men, and negative attitudes regarding HIV prevention; subgroups among MSM were found to have differential HIV transmission risk behaviors, with young men more vulnerable to infection with HIV. Conclusion: Sociocultural factors, including external socioenvironmental circumstances and internal MSM community subcultures, have adverse impacts on HIV transmission among men who have sex with men. Because there were varied behavior modes and HIV transmission risks among MSM subgroups, further study focusing on MSM subgroups is imperative, to provide a basis for more targeted and effective prevention strategies. PMID- 27686763 TI - [Features and influencing factors of self-discrimination among HIV/AIDS patients according to sex]. AB - Objective: To investigate the features and influencing factors of self discrimination among patients with HIV/AIDS according to sex. Methods: A total of 2 432 HIV/AIDS patients were recruited in Yunnan, Henan, Hubei, Jiangsu, Shanxi, Jilin, and Inner Mongolia provinces by a multistage stratified cluster sampling method, based on HIV epidemic and transmission modes, from May 2013 to October 2013. All participants were >=18 years old, and we excluded those with mental disorders, hearing loss or other factors that prevented them from properly answering questions, and those who were unwilling to participate. A self-designed questionnaire was conducted to collect information about self-discrimination features and social behavior changes among HIV/AIDS patients. Differences in performance and self-discrimination features between participants of different sexes were compared using the chi-squared test. Factors influencing self discrimination were analyzed by sex, using unconditional logistic regression. Results: Of the 2 432 cases, 78.9%(1 918 cases)were male and 21.1%(514 cases)female. The proportion of self-discrimination overall was 76.1%(1 850 cases); this proportion among female HIV/AIDS patients was 80.5%(414 cases), which was higher than that among men(74.9%, 1 436 cases)(chi2=7.17, P=0.007). Of the 11 forms of self-discrimination performance, proportions of feeling guilt, shame, and self-abasement among participants were greater than 50%. Proportions of feeling shame, inferiority, and blaming others among females were 61.3%, 59.5%, and 45.3%, respectively, which were higher than these among males(49.8%, 50.0%, 28.4%, respectively)(P<0.01). Multivariate unconditional logistic regression analysis showed that the risk of self-discrimination among those with HIV confirmatory testing time >=1 year was higher than those with HIV confirmatory testing time <1 year(females: OR=35.67, 95%CI:17.28-73.64; males: OR=8.74, 95% CI:6.79-11.25). Compared with other occupations, the risk of self discrimination among male farm workers was higher(OR=1.62, 95% CI:1.03-2.54). The risks of self-discrimination in males who had been infected with HIV by transmission routes of blood transfusion or blood collection(OR=2.38, 95% CI:1.31 4.30), injection drug use(OR=1.78, 95% CI:1.09-2.91), and male-to-male sexual behavior(OR=1.48, 95%CI:1.08-2.03)were higher than in males infected via heterosexual behavior. Conclusion: Female HIV/AIDS patients are more likely to engage in self-discrimination than male patients. Self-discrimination mainly takes the form of feeling remorse, shame, and inferiority. Confirmatory testing time >=1 year, occupation as a farm work, and routes of transmission via blood transfusion or collection, injection drug use, and male-to-male sexual behavior are influencing factors of self-discrimination among male HIV/AIDS patients. Confirmatory testing time >=1 year is the influencing factor of self discrimination among female HIV/AIDS patients.

AB - Objective: To investigate the number and distribution of N-linked glycosylation sites of simian/human immunodeficiency virus envelope proteins(SHIVSF162P3)and SHIV transmission. Methods: Two female adult Chinese rhesus macaques(4 years old)were intravenously inoculated with 300 TCID50 SHIVSF162P3. The macaques weighed 4 and 5 kg and were identified as Rh1 and Rh2. We collected plasma samples at days 3, 7, 10, 14, 17, 21, 24, 28, 35, 42, 49, 56, 63, 70 and 77 post challenge. Subsequently, we monitored plasma viral load by real-time PCR after viral RNA isolation and cDNA synthesis. We amplified the full-length envelope gene by single genome amplification(SGA)at days 7, 14, 28 and 77. BioEdit, MEGA, and the HIV Databases were used to analyze envelope sequences. Sequence diversity and N-linked glycosylation sites were compared between virus stock and plasma viruses of the two macaques. Results: A total of 55 env sequences were obtained from virus stock and their average pairwise distances were(0.166 6+/- 0.096 3)%. Viral loads peaked at 7.68 and 7.49 log10 copies/ml at day 10 and reached the set point at day 42(4.27 and 4.81 log10 copies/ml). The percentages of envelope sequences containing 25 potential N-linked glycosylation sites(PNGSs)were 83%(20/24)and 94%(29/31)in Rh1 and Rh2, respectively, at day 7; these were significantly higher than the proportion in SHIVSF162P3 stock(49%(27/55)). Viral diversity after infection increased with time whereas the proportion of sequences containing 25 PNGSs decreased and sequences containing 27 PNGSs gradually increased. In Rh1, the percentage of sequences containing 27 PNGSs increased to 29% at day 28 and reached 35% at day 77 in Rh2. By analyzing the number of PNGSs in the V1-V5 regions, we found that PNGS variation mainly occurred in the V4 loop. Compared with sequences containing 27 PNGSs, a seven amino acid(TWNNTIG)deletion was found in the V4 loop, which resulted in a loss of two PNGSs at positions 392 and 396. Conclusion: Low glycosylation of the SHIVSF162P3 V4 loop may facilitate spread of the SHIV virus whereas viruses with highly glycosylated V4 loops showed replication advantages after infection. PMID- 27686765 TI - [Impact of PM2.5 on daily outpatient numbers for respiratory diseases in Shenzhen, China]. AB - Objective: To assess the association between the concentration of the air pollutant PM2.5 and daily outpatient visits for respiratory disease. Methods: All records of daily outpatient visits to three hospitals in Shenzhen from January 1 to December 31, 2013 were collected. Daily air pollution monitoring and meteorology data from the same period were also collected in Shenzhen. The data were analyzed using a semiparametric generalized additive model with Poisson distribution of time series analysis controlling for long-term and seasonal trends, flu, DOW, public holidays, and meteorological factors. The excess risk(ER)of respiratory disease and its 95% CI value were calculated, along with the incremental increase of 10 MUg/m3 in PM2.5 concentration. Results: Number of outpatient visits for respiratory diseases totaled 1 428 672(daily range: 1 790-5 228). The annual average PM2.5 concentration was 40.2 MUg/m3(daily range: 7.2 137.1 MUg/m3). The lag1 factor had the most significant impact on the lag effect. We estimated that a 10 MU g/m3 increase in day-before PM2.5 concentration was associated with a 1.809%(95% CI: 1.709%-1.909%)ER of visits for respiratory disease. After controlling for other pollutants(NO2, CO, and O3), the effect remained stable. When NO2, CO, and O3 were introduced separately, for every 10 MUg/m3 rise in PM2.5 concentration, the excess risk of daily outpatient visits for respiratory disease was 1.814%(95% CI: 1.706%-1.923%), 2.780%(95% CI: 2.668% 2.892%), and 1.513%(95% CI: 1.403%-1.624%), respectively. With simultaneous control of NO2 and O3, NO2 and CO, and CO and O3, for every 10 MUg/m3 rise in PM2.5 concentration, the excess risk of respiratory disease was 1.369%(95% CI: 1.242%-1.497%), 2.709%(95% CI: 2.590%-2.828%), and 2.577%(95% CI: 2.452%-2.702%), respectively. With simultaneous control of NO2, CO, and O3, for every 10 MUg/m3 rise in PM2.5 concentration, the excess risk of respiratory disease was 2.370%(95% CI: 2.231%-2.509%). Conclusions: PM2.5 can increase the risk of outpatient visits for respiratory disease in Shenzhen. PMID- 27686766 TI - [Study of survival factors of oral squamous cell carcinoma]. AB - Objective: To explore the survival factors for oral squamous cell carcinoma(OSCC). Methods: A total of 492 patients with OSCC were recruited from the First Affiliated Hospital of Fujian Medical University from June 2003 to December 2014. Then, 456 cases were included in the present study according to inclusion and exclusion criteria. Clinical and follow-up data were collected to evaluate survival factors of OSCC. Survival rates were calculated using the Kaplan-Meier method and compared using the Log-rank test. The Cox proportional hazards regression model was used to estimate the hazard ratio(HR)and 95% confidence intervals(CI)of survival factors. We also stratified by TNM Classification of Malignant Tumours stage and BMI to assess the association between treatments and OSCC outcomes. Results: The age of the recruited patients was(57.89+/-11.61)years, and the proportions in TNM stages I, II, III, and IV were 14.0%(64), 23.7%(108), 16.1%(73)and 42.5%(194), respectively. The multivariate Cox regression indicated that the HR(95% CI)of the increase to mortality risk associated with stage T2-T3, T4(T1 as reference), stage N2-N3(N0 as reference), poormoderate differentiation, BMI<18.5 kg/m2(compared with BMI 18.5-23.9 kg/m2), alcohol consumption >=20 g/d(compared with no alcohol)before treatment were 2.69(1.21-5.95), 3.40(1.54-7.53), 2.65(1.17-6.00), 2.56(1.39 4.71), 2.00(1.15-3.50), 2.09(1.11-3.93), and 1.68(1.03-2.73), respectively. The stratification analysis demonstrated that, compared with surgery alone, surgery combined with radiotherapy reduced the mortality risk of stage III-IV, HR(95% CI)0.33(0.12-0.93). Surgery combined with chemoradiotherapy reduced the mortality risk of OSCC with normal BMI, HR(95% CI)were 0.39(0.17-0.87). Conclusions: Clinical stage and histological grade are survival factors for patients with OSCC. PMID- 27686767 TI - [Analysis for the breast cancer screening among urban populations in China, 2012 2013]. AB - Objective: To analyze results of breast cancer screenings in the Cancer Screening Program in Urban China(CanSPUC)during 2012-2013. Methods: In 14 cities of 9 provinces(Eastern Region: Beijing, Hebei, Liaoning, Shandong and Guangdong; Central Region: Heilongjiang and Hunan; Western Region: Chongqing and Gansu), 198 097 women aged 40-69 years who had lived in their cities for >=3 years were surveyed through a cancer risk assessment questionnaire during 2012-2013. The questionnaires identified women considered to be at high risk for breast cancer, of whom 17 104 received screening examinations, for whom complete records of breast cancer screening and other data were available for 12 440 subjects altogether, including breast ultrasound exams for subjects 40-44 years old. Subjects older than 45 years or in whom breast imaging reporting and data system(BI-RADS)ultrasound had found >= 3 lesions also underwent mammography. In this cohort, BI-RADS 3 class was defined as suspicious and BI-RADS >=4 class as positive. Chi-square tests were used to compare breast cancer screening results by groups. Results: As of October 2013, breast cancer screening percentages for the 12 440 subjects for whom full data were available were, by region, Eastern: 55.43%(6 895); Central: 21.45%(2 669); and Western: 23.12%(2 876); by age, 40-44 years: 5.50%(684); >=45 years: 94.50%(11 756). Using BI-RADS, 2018 subjects were found to have 3 lesions(detection rate: 16.22%), which were distributed regionally as Eastern: 19.00%(1 310 women), Central: 13.75%(367)and Western; 11.86%(341); chi2=91.45, P<0.001; and 289 were found to have >=4 lesions(detection rate: 2.32%), which were distributed regionally as Eastern: 2.41%(166), Central: 1.54%(41)and Western; 2.85%(82); chi2=11.04, P=0.004. Women aged 50-54 years had the highest detection rate of BI-RADS 3 lesions at 18.74%(561/2 994), and those aged 40-44 years had the highest detection rate of BI-RADS >=4 at 2.92%(20/684). Conclusion: Detection rates of BI-RADS >=4 lesions were highest in the Western region and in women aged 40-44 years, and lowest in the Central region and in women aged 60-64 years. Detection rates of BI-RADS 3 lesions were highest in the Eastern region and in women aged 50-54 years and the lowest in the Western region and in women aged 60-64 years. PMID- 27686768 TI - [Association of exposure to environmental chemicals with risk of childhood acute lymphocytic leukemia]. AB - Objective: This study aimed to investigate the association between exposure to environmental chemicals and the risk of childhood acute lymphocytic leukemia(cALL). Methods: A case-controlled study was conducted in Shenzhen Children's Hospital, China from January 2015 to January 2016. The cases were selected from the section of Hematology and Oncology, and the controls were selected from Orthopedics by 1?2 matching of cases according to sex and age. A questionnaire including population data and chemical exposure characteristics was conducted on the children's parents, and urine and EDTA-blood were collected from the children. Then, we quantitatively measured the internal dose of formaldehyde(i.e., formaldehyde-human serum albumin)by enzyme-linked immunosorbent assay and the doses of metabolites benzene, toluene, and xylene(i.e., trans-muconic acid, hippuric acid, and methylhippuric acid)by high performance liquid chromatography. Logistic regression models were used to analyze the relationships between exposure factors measured from children and their parents and cALL. Results: In the study, 71 cases(average age: 6.08+/-3.61 years), and 142 controls(average age: 5.91+/-3.57 years)were assessed; there were no differences in general demographics between two groups. The self-reported results showed that living in a home that had been painted in the past 10 years(OR=4.39, 95% CI: 1.87-10.31), maternal chemical exposure during pregnancy(OR=11.78, 95% CI: 1.65-83.88), paternal diesel or gasoline exposure(OR=8.15, 95% CI: 2.68-24.83), paternal dye exposure(OR=7.77, 95% CI: 1.52-39.67)and trash burning near the child's residence(OR=6.08, 95% CI: 1.17 31.66)were associated with increased risk of cALL. The positive detection rates of only benzene metabolites were significantly higher in cases(40/44)than controls(81/111)(chi2=5.92, P=0.021). The median formaldehyde and benzene concentrations in cases(32.120 pg/ml, 2.505 MUg/gCr)were significantly higher than those in controls(18.705 pg/ml, 0.672 MUg/gCr; Z values:-1.98 and-3.95, P values: 0.047 and<0.001, respectively). Multiple logistic regression analysis showed that benzene exposure(OR=1.09, 95% CI: 1.00-1.19), home painting in the past 10 years(OR=3.56, 95% CI: 1.20-10.53)and paternal diesel or gasoline exposure(OR= 3.75, 95% CI: 1.06-13.22)were associated with increased risk of cALL. Conclusion: A variety of environmental chemistry factors, such as benzene exposure, increase the risk of cALL, and further studies are warranted to explore their specific roles. PMID- 27686769 TI - [Association and interaction of heat shock proteins B1 gene and tumor-suppressor protein p53 gene with chromosome damage levels among coke oven workers]. AB - Objective: To investigate the association and interaction of heat shock proteins B1(HSPB1)gene rs2868371 and tumor-suppressor protein p53(TP53)gene rs1042522 polymorphisms with chromosome damage levels among coke oven workers. Methods: We recruited 1 333 male workers from a state-run coke oven plant in Wuhan in September-October 2010. Among them, 949 who had worked in coke oven workplaces, including auxiliary facilities and bottom, side, and top ovens, were nominated as coke oven workers(i.e., exposed), and 384 administrative or medical staff whose workplaces were offices were used as controls. General characteristics and 5 ml of venous blood were collected from each participant. The plasma concentrations of benzo[a]pyrene-diolepoxide(BPDE)-albumin adducts and the lymphocytic micronucleus(MN)frequencies for each individual were detected by ELISA and cytokinesis-block micronucleus assay, respectively. Gene polymorphisms were genotyped using TaqMan assays via quantitative PCR(ABI Prism 7900HT), and the corresponding frequency ratios(FR)with 95% confidence intervals(CI)were computed for all assays. Results: In the exposed group, the MN frequencies were higher in HSPB1 rs2868371 GC, CC, and GC+ CC genotype carriers((3.88 +/- 2.88)0/00,(4.00 +/ 2.66)0/00, and(3.91 +/- 2.83)0/00, respectively)than in rs2868371 GG genotype carriers((3.52+/-2.67)0/00; FR=1.10, 1.13, and 1.11; 95% CI: 1.02-1.19, 1.02 1.25, and 1.03-1.19, respectively), and the HSPB1 rs2868371C allele was associated with increased MN frequency(Ptrend=0.006). Further, in the exposed group, the MN frequencies were lower in TP53 rs1042522 CG and CG+GG genotype carriers((3.63+/-2.61)0/00 and(3.66+/-2.61)0/00, respectively)than in TP53 rs1042522 CC genotype carriers(3.95+/-3.06)0/00(FR=0.87 and 0.90; 95% CI: 0.83 0.96 and 0.84-0.97, respectively). The effect of gene-gene interaction between HSPB1, rs2868371, and TP53 rs1042522 on MN frequency was significant among coke oven workers(P=0.001). Further stratified analyses showed that the effects of the HSPB1 rs2868371C allele in increasing MN frequencies were robust in subjects aged >40 years(FR=1.07, 95% CI: 1.01-1.12), those working >20 years(FR=1.08, 95% CI: 1.02-1.14), those with BMI <=24 kg/m2(FR=1.07, 95% CI: 1.01-1.13), drinkers(FR=1.09, 95% CI: 1.02-1.16), and workers with higher BPDE-albumin adduct levels(FR=1.07, 95% CI: 1.01-1.13)(Ptrend=0.023, 0.013, 0.029, and 0.020, respectively). The decreasing effect of the TP53 rs1042522 G allele on MN frequencies was robust in subjects aged >40 years(FR=0.94, 95% CI: 0.89-0.99), those with BMI <=24 kg/m2(FR=0.94, 95% CI: 0.88-0.99), and drinkers(FR=0.94, 95% CI: 0.88-1.00)(Ptrend=0.031, 0.023, and 0.038, respectively). In addition, there were interactions between HSPB1 rs2868371 and age and between HSPB1 rs2868371 and working years in terms of MN frequency(P=0.030 and 0.013, respectively). Conclusion: In coke oven workers, the HSPB1 rs2868371 C and TP53 rs1042522 G alleles were associated with increased and decreased chromosome damage levels, respectively, and their interaction effect on chromosome damage levels was significant. PMID- 27686770 TI - [Survey on fungi contamination and natural occurrence of mycotoxins in 94 corn feed ingredients collected from China]. AB - Objective: To investigate fungi contamination and the natural occurrence of mycotoxins in corn feed ingredients collected from China. Methods: A total of 94 corn feed ingredient samples were collected from 8 Chinese provinces(i.e., Anhui, Hebei, Heilongjiang, Jilin, Jiangsu, Liaoning, Inner Mongolia, and Shandong)in February 2014. A tandem ultra-performance liquid chromatographymass spectrometry method was used for simultaneous detection of twelve kinds of mycotoxins, including aflatoxin(AF), type A and type B tricothecenes, and zearalenone(ZEN). Contaminated fungi were also identified and counted. Results: AF was detected in 36.2%(34/94)of samples; the concentration of AFB1 was the highest in the four AFs with the range: 0.3~181.3 MUg/kg; and then followed by AFB2(range: 1.0-74.3 MUg/kg). There were 7 samples(7.5%)with AFB1 concentrations higher than the tolerance limit of 50 MUg/kg. The concentration of type A tricothecenes in all samples was lower(0.1-10.5 MUg/kg). DON had the most serious contamination than other kind of type B tricothecenes(range: 0.7-606.6 MUg/kg; median: 66.3 MUg/kg). The DON concentration in all samples was below the tolerance limit of 1 000 MUg/kg. ZEN was detected in 76.6%(72/ 94)of samples(median: 36.9 MUg/kg), with 3 samples having ZEN concentrations higher than the tolerance limit of 500 MUg/kg. The survey on fungi contamination showed that all samples were contaminated by fungi(range: 5.0-1.4*105 CFU/g). There were 18 and 3 samples with quantities of fungi higher than the tolerance and forbidden limits, respectively. The Aspergillus, Penicillium, Fusarium, Trichoderma and Mucor genuses were the predominant fungi in corn feed ingredients, with detection rates of 71.3%(67), 60.6%(57), 71.3%(67), 27.7%(26), and 24.5%(23), respectively. The detection rate of Fusarium moniliforme, 73.4%(69/94)was higher than that of Aspergillus flavus, 41.5%(39/94). Conclusion: In this survey, the corn feed ingredients were not seriously contaminated by AF and type A tricothecenes but mainly contaminated by type B trichothecenes, including DON and its derivatives, as well as ZEN. They were also contaminated by fungi such as Aspergillus, Penicillium, and Fusarium.

AB - Parkinson's disease(PD)was the second most common neurodegenerative disorder after Alzheimer's disease. Incidence of PD was ascending year by year. The etiology of PD is poorly understood, involving aging, genetic and environmental factors. Recently, environmental compound had attracted more and more research interest. Studies and extrapolation from epidemiology, animal experiments and cell culture suggested that environmental compound had involved in the molecular mechanisms including mitochondrial dysfunction, oxidative stress, microglia activation, abnormal aggregation of alpha-synuclein and autophagy damage ,which seemed to increase PD risk.

PMID- 27686778 TI - Folliculitis in prurigo pigmentosa: a proposed pathogenesis based on clinical and pathological observation. AB - BACKGROUND: Prurigo pigmentosa is a rare inflammatory dermatosis whose exact etiology is not understood yet. The purpose of this study was to provide evidence of hair follicle involvement in the pathogenesis by analyzing its clinicopathologic features. METHODS: Patients who fulfilled both the clinical and histological diagnostic criteria of prurigo pigmentosa were recruited. Their histopathologic findings, clinical features and medical histories were analyzed. RESULTS: A total of 32 confirmed patients were enrolled from 2002 to 2013. Their ages ranged from 11 to 79 years with a female predominance. Patient lesions were primarily reddish-brown and located on the back. A total of 25 patients (78%) had pathological involvement of hair follicles, either bacterial colonies in the hair follicles (21/32, 66%), folliculitis (8/32, 25%) or perifolliculitis (15/32, 47%). There was a significantly higher proportion of patients with hair follicle involvement compared with control groups with either noninflammatory (5/43, 12%, p < 0.001) or inflammatory skin diseases (12/32, 38%, p = 0.002) on the back. Minocycline was an effective antibiotic treatment either singly or in combination with steroids. CONCLUSIONS: The frequent presence of bacterial colonies along with sequelae of inflammatory changes on biopsy provides new evidence to support the theory that prurigo pigmentosa is a reactive inflammation associated with bacterial folliculitis. PMID- 27686779 TI - Concentrating Emergency Rooms: Penny-Wise and Pound-Foolish? An Empirical Research on Scale Economies and Chain Economies in Emergency Rooms in Dutch Hospitals. AB - In this paper, we address the issue of whether it is economically advantageous to concentrate emergency rooms (ERs) in large hospitals. Besides identifying economies of scale of ERs, we also focus on chain economies. The latter term refers to the effects on a hospital's costs of ER patients who also need follow up inpatient or outpatient hospital care. We show that, for each service examined, product-specific economies of scale prevail indicating that it would be beneficial for hospitals to increase ER services. However, this seems to be inconsistent with the overall diseconomies of scale for the hospital as a whole. This intuitively contradictory result is indicated as the economies of scale paradox. This scale paradox also explains why, in general, hospitals are too large. There are internal (departmental) pressures to expand certain services, such as ER, in order to benefit from the product-specific economies of scale. However, the financial burden of this expansion is borne by the hospital as a whole. The policy implications of the results are that concentrating ERs seems to be advantageous from a product-specific perspective, but is far less advantageous from the hospital perspective.

AB - Residents of Southwest Virginia (SWVA) face significant barriers in accessing the most advanced forms of cancer care, cancer risk reduction, and clinical trials involvement. A collaboration between the University of Virginia (UVA) Cancer Center and UVA School of Nursing was forged with oncology caregivers in this region to build community capacity to support Cancer Clinical trials (CCT) by strengthening the workforce, and thus improving health outcomes for this underserved region of Appalachia. The UVA School of Nursing designed an educational workshop focusing on the basics of CCT to facilitate the development of a skilled nursing workforce in the SWVA region that could provide care to patients on protocol and/or to encourage residents to participate in trials. The goal of the workshop was to offer a CCT training session for oncology nurses that fostered the knowledge and skills necessary to facilitate and support CCT infrastructure across this high-risk region. This evaluation reports the learning outcomes of the CCT training on 32 nurse participants from SWVA. Evaluations of the training program showed high rates of satisfaction, increased comfort level with CCTs, and increased knowledge and attitude toward CCTs. These findings provide information about a curriculum that could be useful in educating other oncology nurses and student nurses how to care for patients who may be enrolled in a clinical trial. Nurses can also be advocates for participation in clinical trials once they have the knowledge and are comfortable in their own understanding of a trial's usefulness. Educating the nursing workforce is an essential component of building capacity and infrastructure to support clinical trials research. PMID- 27686781 TI - Determinants of Potentially Inappropriate Medication Use among Community-Dwelling Older Adults. AB - OBJECTIVE: To examine the determinants of potentially inappropriate medication (PIM) use. DATA SOURCES/STUDY SETTING: U.S. nationally representative data on (n = 16,588) noninstitutionalized older adults (age >=65) with drug use from the 2006-2010 Medical Expenditure Panel Survey. STUDY DESIGN: We operationalized the 2012 Beers Criteria to identify PIM use during the year, and we examined associations with individual-level characteristics hypothesized to be quality enabling or related to need complexity. PRINCIPAL FINDINGS: Almost one-third (30.9 percent) of older adults used a PIM. Multivariate results suggest that poor health status and high-PIM-risk conditions were associated with increased PIM use, while increasing age and educational attainment were associated with lower PIM use. Contrary to expectations, lack of a usual care source of care or supplemental insurance was associated with lower PIM use. Medication intensity appears to be in the pathway between both quality-enabling and need-complexity characteristics and PIM use. CONCLUSION: Our results suggest that physicians attempt to avoid PIM use in the oldest old but have inadequate focus on the high PIM-risk conditions. Educational programs targeted to physician practice regarding high-PIM-risk conditions and patient literacy regarding medication use are potential responses. PMID- 27686782 TI - An Overview of Treatment Methods for Primary Angle Closure. AB - BACKGROUND: Glaucoma is the second leading cause of blindness in the world. Angle closure glaucoma accounts for 25% of all glaucoma, with Asia having the highest rate. Angle closure is an anatomical variation, making the Inuit, Chinese, and other Asians more susceptible. Current treatments include medical, laser, and surgical modalities. PURPOSE: To identify the current treatment protocols for primary angle closure. DISCUSSION: The current general protocol to treat angle closure is to lower the intraocular pressure with medications and perform laser iridotomy. However, cataract surgery, laser iridoplasty, goniosynechiolysis, diode cyclophotocoagulation, and filtering surgery are additional treatment modalities used for primary angle closure. CONCLUSION: Primary angle closure occurs due to various anatomical angle variations. Laser iridotomy is not the sole method of treatment. Specifically, cataract surgery can be particularly effective in the treatment and prevention of angle closure. Recalcitrant cases can be treated with trabeculectomy and shunt implants, although these are not usually first-line treatments.

AB - In recent years, wildlife conservation has attracted great public attention. However, substantial distinctions can be found in the prevailing concepts of wildlife conservation, particularly with the recent notion that emphasizes animal rights. Wildlife welfare and wildlife rights are not synonymous, with welfare more compatible with the reasonable and legal utilization of wildlife. The key to scientific wildlife conservation is the appropriate awareness and appreciation of the relationship between wildlife conservation and utilization and the theoretical basis of holism. Nevertheless, rational biases regarding the public's understanding of wildlife conservation and the spread of information via social media still exist. As such, expansion of the concept of scientific wildlife conservation requires the application of several measures. Wildlife conservation researchers should be regarded as the most important disseminators of scientifically-based information, with education in schools and universities of growing importance. Furthermore, the media should shoulder the social responsibility for the accurate dissemination of conservation information. PMID- 27686784 TI - Lamprey: a model for vertebrate evolutionary research. AB - Lampreys belong to the superclass Cyclostomata and represent the most ancient group of vertebrates. Existing for over 360 million years, they are known as living fossils due to their many evolutionally conserved features. They are not only a keystone species for studying the origin and evolution of vertebrates, but also one of the best models for researching vertebrate embryonic development and organ differentiation. From the perspective of genetic information, the lamprey genome remains primitive compared with that of other higher vertebrates, and possesses abundant functional genes. Through scientific and technological progress, scientists have conducted in-depth studies on the nervous, endocrine, and immune systems of lampreys. Such research has significance for understanding and revealing the origin and evolution of vertebrates, and could contribute to a greater understanding of human diseases and treatments. This review presents the current progress and significance of lamprey research. PMID- 27686786 TI - What is the destiny of a threatened fish, Ptychobarbus chungtienensis, now that non-native weatherfishes have been introduced into Bita Lake, Shangri-La? AB - Biological invasion is a pervasive negative force of global change, especially in its effects on sensitive freshwater ecosystems. Even protected areas are usually not immune. Ptychobarbus chungtienensis is a threatened freshwater fish now almost confined to Bita Lake, in the Shangri-La region of Yunnan province, China. Its existence is threatened by the introduction of non-native weatherfishes (Misgurnus anguillicaudatus and Paramisgurnus dabryanus) by an unusual method known as 'prayer animal release'. Periodic surveys revealed the ratio of invasive weatherfishes to P. chungtienensis has been increasing since the former species was first recorded from the lake in August, 2009. Ptychobarbus chungtienensis shows low genetic diversity in the relict Lake Bita population. Weatherfishes, however, have highly successful survival strategies. The degree of dietary overlap between the species is alarming and perhaps critical if food is found to be a limiting factor. PMID- 27686788 TI - A new species of the genus Triplophysa (Cypriniformes: Nemacheilidae), Triplophysa daochengensis, from Sichuan Province, China. AB - Triplophysa daochengensis sp. nov. is described from the Daocheng River, a northern tributary of the Jinsha River in Sichuan Province, China. The new species can be distinguished from its congeners by the following characters: body smooth and scales absent; lateral line complete; caudal peduncle compressed, depth unchanging; head length equal to caudal-peduncle length; lower jaw shovel shaped; dorsal-fin origin anterior to pelvic-fin origin and closer to the tip of the snout than to the caudal-fin base, last unbranched ray hard; pelvic-fin tip not reaching anus; posterior chamber of gas bladder absent; intestine of spiral type with three winding coils. PMID- 27686787 TI - Evolution and phylogenetic application of the MC1R gene in the Cobitoidea (Teleostei: Cypriniformes). AB - Fish of the superfamily Cobitoidea sensu stricto (namely loaches) exhibit extremely high diversity of color patterns, but so far little is known about their evolutionary mechanism. Melanocortin 1 receptor gene (MC1R) plays an important role during the synthesis of melanin and formation of animal body color patterns. In this study, we amplified and sequenced the partial MC1R gene for 44 loach individuals representing 31 species of four families. Phylogenetic analyses yielded a topology congruent with previous studies using multiple nuclear loci, showing that each of the four families was monophyletic with sister relationships of Botiidae+ (Cobitidae+(Balitoridae+Nemacheilidae)). Gene evolutionary analyses indicated that MC1R in loaches was under purifying selection pressure, with various sites having different dN/dS values. Both Botiidae and Cobitidae had lower dN/dS values than those of background lineages, suggesting their evolution might be strongly affected by purifying selection pressure. For Balitoridae and Nemacheilidae, both had larger dN/dS values than those of background lineages, suggesting they had a faster evolutionary rate under more relaxed selection pressure. Consequently, we inferred that the relatively stable color patterns in Botiidae and Cobitidae might result from the strong purifying selection pressure on the MC1R gene, whereas the complicated and diverse color patterns in Balitoridae and Nemacheilidae might be associated with the relaxed selection pressure. Given the easy experimental procedure for the partial MC1R gene and its excellent performance in reconstructing phylogeny, we suggest this gene could be used as a good molecular marker for the phylogenetic study of fish species. PMID- 27686789 TI - A new cave species of the Genus Triplophysa from Yunnan, China. AB - In September and October 2015, a new species of the family Nemacheilidae, Triplophysa tianxingensis sp. nov., was discovered from underground water in Qiubei County, Yunnan Province, China. It can be distinguished from all other troglobiotic Triplophysa species occurring in Yunnan by the following combination of characters: eyes small, a little degenerated; barbels longer; ventral profiles greatly convex; pectoral fin short, attaining a third of the distance from the pectoral-fin base to pelvic fin base; body with many brown blotches; caudal peduncle with fin fold; caudal fin shallowly forked, and free posterior chamber of swim bladder cylindrical. PMID- 27686790 TI - Identification of candidate piRNAs in the gonads of Paralichthys olivaceus (Japanese flounder). AB - Piwi-interacting RNA (piRNA) plays an important role in the gonadal development and maintenance of Teleostei. In this study, piRNA libraries derived from the adult gonads of Japanese flounder (Paralichthys olivaceus) were generated using next-generation sequencing technology. Using zebrafish piRNAs as a reference, 5 865 unique candidate piRNAs were identified; 289 candidate piRNA clusters (PRCs) were generated from the above piRNAs. Among the isolated candidate PRCs, a total of 38 ovary-specific, 45 ovary-bias, 24 testis-specific, and 131 testis-bias PRCs were found. The relative expression levels of seven PRCs were validated through quantitative reverse transcription-polymerase chain reaction. The results of this study will help facilitate exploration of the development and maintenance of the phenotypic sex mechanism in P. olivaceus. PMID- 27686791 TI - Identification of Sphaeroma terebrans via morphology and the mitochondrial cytochrome c oxidase subunit I (COI) gene. AB - Sphaeroma terebrans, a wood-boring isopoda, is distributed worldwide in tropical and subtropical mangroves. The taxonomy of S. terebrans is usually based on morphological characteristics, with its molecular identification still poorly understood. The number of teeth on the uropodal exopod and the length of the propodus of the seventh pereopod are considered as the major morphological characteristics in S. terebrans, which can cause difficulty in regards to accurate identification. In this study, we identified S. terebrans via molecular and morphological data. Furthermore, the validity of the mitochondrial cytochrome c oxidase subunit I (COI) gene as a DNA barcode for the identification of genus Sphaeroma, including species S. terebrans, S. retrolaeve, and S. serratum, was examined. The mitochondrial COI gene sequences of all specimens were sequenced and analysed. The interspecific Kimura 2-parameter distances were higher than intraspecific distances and no intraspecific-interspecific distance overlaps were observed. In addition, genetic distance and nucleotide diversity (pi) exhibited no differences within S. terebrans. Our results revealed that the mitochondrial COI gene can serve as a valid DNA barcode for the identification of S. terebrans. Furthermore, the number of teeth on the uropodal exopod and the length of the propodus of the seventh pereopod were found to be unreliable taxonomic characteristics for S. terebrans. PMID- 27686792 TI - Authorship misconduct. PMID- 27686793 TI - Eradication of Helicobacter spp. in mucin2-deficient mice. AB - Infections with Helicobacter spp. are known to have serious effects on rodent health, especially in immunocompromised animals. In this study three approaches were used to eradicate Helicobacter spp. infection in mice with a deficiency in intestinal proteoglycan (mucin2), namely triple oral antibiotic therapy (amoxicillin, clarithromycin and metronidazole), cross-fostering of neonatal pups by surrogate mothers negative for Helicobacter spp., and in vitro fertilization (IVF) with embryo transfer into Helicobacter-free mothers. However, triple antibiotic therapy in mice with mucin2 deficiency was not effective and had negative effects on reproductive performance, and high susceptibility of mucin2 deficient mice to Helicobacter spp. during the first 12 h after birth rendered cross-fostering impossible. Only IVF with embryo transfer was effective in eradicating Helicobacter infection from transgenic mice with mucin2 deficiency. PMID- 27686794 TI - Post-trabeculectomy ocular biometric changes. AB - Trabeculectomy is the most common surgical procedure for the management of glaucoma, which may significantly influence ocular biometry. Axial length and anterior chamber depth tend to decrease, while crystalline lens and choroidal thickness increase post-operatively. An increase in with-the-rule astigmatism is also observed after the procedure. Such biometric changes affect intraocular lens power calculation even years after the procedure. Non-contact biometric methods and postponing cataract surgery after trabeculectomy could reduce calculation errors associated with surgically induced alterations in ocular biometrics. PMID- 27686795 TI - Emerging treatments for severe obesity in children and adolescents. AB - Severe obesity in childhood is increasing in prevalence and is associated with considerable morbidity. Studies into pediatric obesity have focused largely on interventions that do not necessarily target the unique biologic or psychological underpinnings for the weight gain in the individual child or adolescent. Outcomes show modest improvement and are of questionable benefit for patients with severe obesity. Although weight is a commonly used outcome, other psychological and metabolic parameters including normalization of physical activity and eating behaviors should be primary outcome goals. The durability of weight loss is often limited by physiologic systems that are evolutionarily designed to promote weight gain. Drug therapies for children are limited, as is their effect on weight and metabolism. Existing drugs that are incidentally found to cause weight loss through off-target effects are being actively investigated for obesity indications. Bariatric surgery results in the most significant weight reduction, but it is associated with potential morbidity and long term data are not available for adolescents undergoing this procedure. As understanding of the biologic and psychosocial contributors to eating behaviors and body weight regulation increases, multifaceted and targeted behavioral, pharmacological, and surgical treatment algorithms should be developed and applied to target the underlying pathways involved for the individual child or adolescent with severe obesity. PMID- 27686796 TI - A computer program to simplify analysis of mass scan data of organometallic compounds from high-resolution mass spectrometers. AB - RATIONALE: Software accompanying high-resolution mass spectrometers, particularly that used for the analysis of organometallic compounds, has lagged the technology of the instruments themselves. We have developed a computer program that partially fills this gap. METHODS: Given the user's expectation for the number of atoms of a target element likely to be in an ion, the program calculates isotopologue mass differences for combinations of that element's isotopes and their expected intensity ratios relative to the most abundant isotopologue. These values are compared with mass differences and intensity ratios found in the experimental mass scan data and these metrics feed into a four-factor scoring model which ranks the ions as to the likelihood of each containing the specified number of the target atoms. The program was tested using experimental data obtained for selenomethionine. RESULTS: Across a broad range of sample concentrations, the program consistently ranked selenomethionine at or near the top of the list of ions that passed the screening and ranking process. Mass scan data files in excess of 24,000 records were analyzed in less than one second. CONCLUSIONS: The program is quick and efficient at scanning voluminous experimental data files for the presence of ions containing the expected number of atoms of a target element. Best results were obtained the scarcer the target element and the more isotopes it comprised. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27686797 TI - A systematic review of measurement properties of the instruments measuring health related quality of life in patients with irritable bowel syndrome. AB - PURPOSE: The systematic review of patient-reported outcome instruments can allow the selection of the most appropriate instrument for use in research and clinical practice. There has been no systematic review of the measurement properties of irritable bowel syndrome (IBS)-specific health-related quality-of-life (HRQOL) instruments. The purposes of this study were to identify all available instruments for measuring the IBS-specific HRQOL and to determine which is the most appropriate instrument to apply in clinical practice. METHODS: A systematic review study was conducted. The MEDLINE, EMBASE, and CINAHL databases were searched. The methodological quality of the included studies was assessed using the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) checklist. The measurement property results of each study were assessed using Terwee's quality criteria. RESULTS: Seven instruments were identified: The Irritable Bowel Syndrome-Quality of Life (IBS-QOL) instrument was the only one that had been analyzed in multiple studies, with each of the remaining six instruments only being analyzed in a single psychometric study. The IBS-QOL demonstrated moderate positive evidence for internal consistency and reliability and is the best instrument based on the currently available evidence. CONCLUSIONS: Even though the IBS-QOL is currently the best instrument, there is conflicting evidence for its underlying structural validity. The factor structure or dimensionality of the IBS-QOL needs to be elucidated further. PMID- 27686798 TI - Long Non-Coding RNA: An Emerging Paradigm of Pancreatic Cancer. AB - Pancreatic cancer remains a worldwide issue and burden that is hard to resolve given its low resection rate and chemo-resistance. Early diagnosis and early treatment are critical for conquering pancreatic cancer. Therefore, new biomarkers for diagnosis and prognosis are urgently needed. Previously, researchers mainly focused on protein-coding genetic and epigenetic changes in many types of cancers, and regarded the noncoding part as waste. Recently, however, long non-coding RNA (lncRNA) has emerged as a major participant in carcinogenesis, as it regulates cell proliferation, migration, invasion, metastasis, chemo-resistance, etc. The underlying mechanisms are summarized as signaling, decoy, guide and scaffold, yet the specific regulation networks remain to be uncovered. Several studies have revealed that some lncRNAs are dysregulated in pancreatic cancer, participating in biological functions. In this review, we will briefly outline the functional lncRNAs in pancreatic cancer, decipher possible mechanisms of lncRNAs, and further explore their significance in pancreatic cancer. PMID- 27686800 TI - Corrigendum. PMID- 27686799 TI - Potential clinical and economic outcomes of active beta-D-glucan surveillance with preemptive therapy for invasive candidiasis at intensive care units: a decision model analysis. AB - Early initiation of antifungal treatment for invasive candidiasis is associated with change in mortality. Beta-D-glucan (BDG) is a fungal cell wall component and a serum diagnostic biomarker of fungal infection. Clinical findings suggested an association between reduced invasive candidiasis incidence in intensive care units (ICUs) and BDG-guided preemptive antifungal therapy. We evaluated the potential cost-effectiveness of active BDG surveillance with preemptive antifungal therapy in patients admitted to adult ICUs from the perspective of Hong Kong healthcare providers. A Markov model was designed to simulate the outcomes of active BDG surveillance with preemptive therapy (surveillance group) and no surveillance (standard care group). Candidiasis-associated outcome measures included mortality rate, quality-adjusted life year (QALY) loss, and direct medical cost. Model inputs were derived from the literature. Sensitivity analyses were conducted to evaluate the robustness of model results. In base-case analysis, the surveillance group was more costly (1387 USD versus 664 USD) (1 USD = 7.8 HKD), with lower candidiasis-associated mortality rate (0.653 versus 1.426 per 100 ICU admissions) and QALY loss (0.116 versus 0.254) than the standard care group. The incremental cost per QALY saved by the surveillance group was 5239 USD/QALY. One-way sensitivity analyses found base-case results to be robust to variations of all model inputs. In probabilistic sensitivity analysis, the surveillance group was cost-effective in 50 % and 100 % of 10,000 Monte Carlo simulations at willingness-to-pay (WTP) thresholds of 7200 USD/QALY and >=27,800 USD/QALY, respectively. Active BDG surveillance with preemptive therapy appears to be highly cost-effective to reduce the candidiasis-associated mortality rate and save QALYs in the ICU setting. PMID- 27686801 TI - Differences in alexithymia and emotional awareness in exhaustion syndrome and chronic fatigue syndrome. AB - Symptoms of Exhaustion Syndrome (ES) and Chronic Fatigue Syndrome (CFS) are overlapping and create difficulties of differential diagnosis. Empirical studies comparing ES and CFS are scarce. This study aims to investigate if there are any emotional differences between ES and CFS. This cross-sectional study compared self-reported alexithymia and observer-rated emotional awareness in patients with ES (n = 31), CFS (n = 38) and healthy controls (HC) (n = 30). Self-reported alexithymia was measured with the Toronto Alexithymia Scale-20 (TAS-20) and emotional awareness with an observer-rated performance test, the Level of Emotional Awareness Scale (LEAS). Additionally, depression and anxiety were scored by the Hospital Anxiety and Depression Scale (HADS). Results show that patients with ES expressed higher self-reported alexithymia in the TAS-20 compared to HC, but had similar emotional awareness capacity in the observer rated performance test, the LEAS. Patients with CFS expressed more difficulties in identifying emotions compared to HCs, and performed significantly worse in the LEAS-total and spent more time completing the LEAS as compared to HC. Correlation and multiple regressions analyses revealed that depression and anxiety positively correlated with and explained part of the variances in alexithymia scores, while age and group explained the major part of the variance in LEAS. Findings of this study indicate that emotional status is different in patients with ES and CFS with respect to both self-reported alexithymia and observer-rated emotional awareness. Emotional parameters should be approached both in clinical investigation and psychotherapy for patients with ES and CFS. PMID- 27686802 TI - Proteogenomic Tools and Approaches to Explore Protein Coding Landscapes of Eukaryotic Genomes. AB - Proteogenomic strategies aim to refine genome-wide annotations of protein coding features by using actual protein level observations. Most of the currently applied proteogenomic approaches include integrative analysis of multiple types of high-throughput omics data, e.g., genomics, transcriptomics, proteomics, etc. Recent efforts towards creating a human proteome map were primarily targeted to experimentally detect at least one protein product for each gene in the genome and extensively utilized proteogenomic approaches. The 14 year long wait to get a draft human proteome map, after completion of similar efforts to sequence the genome, explains the huge complexity and technical hurdles of such efforts. Further, the integrative analysis of large-scale multi-omics datasets inherent to these studies becomes a major bottleneck to their success. However, recent developments of various analysis tools and pipelines dedicated to proteogenomics reduce both the time and complexity of such analysis. Here, we summarize notable approaches, studies, software developments and their potential applications towards eukaryotic genome annotation and clinical proteogenomics. PMID- 27686803 TI - Next Generation Sequencing Data and Proteogenomics. AB - The field of proteogenomics has been driven by combined advances in next generation sequencing (NGS) and proteomic methods. NGS technologies are now both rapid and affordable, making it feasible to include sequencing in the clinic and academic research setting. Alongside the improvements in sequencing technologies, methods in high throughput proteomics have increased the depth of coverage and the speed of analysis. The integration of these data types using continuously evolving bioinformatics methods allows for improvements in gene and protein annotation, and a more comprehensive understanding of biological systems. PMID- 27686804 TI - Proteogenomics: Key Driver for Clinical Discovery and Personalized Medicine. AB - Proteogenomics is a multi-omics research field that has the aim to efficiently integrate genomics, transcriptomics and proteomics. With this approach it is possible to identify new patient-specific proteoforms that may have implications in disease development, specifically in cancer. Understanding the impact of a large number of mutations detected at the genomics level is needed to assess the effects at the proteome level. Proteogenomics data integration would help in identifying molecular changes that are persistent across multiple molecular layers and enable better interpretation of molecular mechanisms of disease, such as the causal relationship between single nucleotide polymorphisms (SNPs) and the expression of transcripts and translation of proteins compared to mainstream proteomics approaches. Identifying patient-specific protein forms and getting a better picture of molecular mechanisms of disease opens the avenue for precision and personalized medicine. Proteogenomics is, however, a challenging interdisciplinary science that requires the understanding of sample preparation, data acquisition and processing for genomics, transcriptomics and proteomics. This chapter aims to guide the reader through the technology and bioinformatics aspects of these multi-omics approaches, illustrated with proteogenomics applications having clinical or biological relevance. PMID- 27686805 TI - Identification of Small Novel Coding Sequences, a Proteogenomics Endeavor. AB - The identification of small proteins and peptides has consistently proven to be challenging. However, technological advances as well as multi-omics endeavors facilitate the identification of novel small coding sequences, leading to new insights. Specifically, the application of next generation sequencing technologies (NGS), providing accurate and sample specific transcriptome / translatome information, into the proteomics field led to more comprehensive results and new discoveries. This book chapter focuses on the inclusion of RNA Seq and RIBO-Seq also known as ribosome profiling, an RNA-Seq based technique sequencing the +/- 30 bp long fragments captured by translating ribosomes. We emphasize the identification of micropeptides and neo-antigens, two distinct classes of small translation products, triggering our current understanding of biology. RNA-Seq is capable of capturing sample specific genomic variations, enabling focused neo-antigen identification. RIBO-Seq can identify translation events in small open reading frames which are considered to be non-coding, leading to the discovery of micropeptides. The identification of small translation products requires the integration of multi-omics data, stressing the importance of proteogenomics in this novel research area. PMID- 27686806 TI - Using Proteomics Bioinformatics Tools and Resources in Proteogenomic Studies. AB - Proteogenomic studies ally the omic fields related to gene expression into a combined approach to improve the characterization of biological samples. Part of this consists in mining proteomics datasets for non-canonical sequences of amino acids. These include intergenic peptides, products of mutations, or of RNA editing events hypothesized from genomic, epigenomic, or transcriptomic data. This approach poses new challenges for standard peptide identification workflows. In this chapter, we present the principles behind the use of peptide identification algorithms and highlight the major pitfalls of their application to proteogenomic studies. PMID- 27686807 TI - Mutant Proteogenomics. AB - Identification of mutant proteins in biological samples is one of the emerging areas of proteogenomics. Despite the fact that only a limited number of studies have been published up to now, it has the potential to recognize novel disease biomarkers that have unique structure and desirably high specificity. Such properties would identify mutant proteoforms related to diseases as optimal drug targets useful for future therapeutic strategies. While mass spectrometry has demonstrated its outstanding analytical power in proteomics, the most frequently applied bottom-up strategy is not suitable for the detection of mutant proteins if only databases with consensus sequences are searched. It is likely that many unassigned tandem mass spectra of tryptic peptides originate from single amino acid variants (SAAVs). To address this problem, a couple of protein databases have been constructed that include canonical and SAAV sequences, allowing for the observation of mutant proteoforms in mass spectral data for the first time. Since the resulting large search space may compromise the probability of identifications, a novel concept was proposed that included identification as well as verification strategies. Together with transcriptome based approaches, targeted proteomics appears to be a suitable method for the verification of initial identifications in databases and can also provide quantitative insights to expression profiles, which often reflect disease progression. Important applications in the field of mutant proteoform identification have already highlighted novel biomarkers in large-scale investigations. PMID- 27686808 TI - Proteogenomic Analysis of Single Amino Acid Polymorphisms in Cancer Research. AB - The integration of genomics and proteomics has led to the emergence of proteogenomics, a field of research successfully applied to the characterization of cancer samples. The diagnosis, prognosis and response to therapy of cancer patients will largely benefit from the identification of mutations present in their genome. The current state of the art of high throughput experiments for genome-wide detection of somatic mutations in cancer samples has allowed the development of projects such as the TCGA, in which hundreds of cancer genomes have been sequenced. This huge amount of data can be used to generate protein sequence databases in which each entry corresponds to a mutated peptide associated with certain cancer types. In this chapter, we describe a bioinformatics workflow for creating these databases and detecting mutated peptides in cancer samples from proteomic shotgun experiments. The performance of the proposed method has been evaluated using publicly available datasets from four cancer cell lines. PMID- 27686809 TI - Developments for Personalized Medicine of Lung Cancer Subtypes: Mass Spectrometry Based Clinical Proteogenomic Analysis of Oncogenic Mutations. AB - Molecular therapies targeting lung cancers with mutated epidermal growth factor receptor (EGFR) by EGFR-tyrosin kinase inhibitors (EGFR-TKIs), gefitinib and erlotinib, changed the treatment system of lung cancer. It was revealed that drug efficacy differs by race (e.g., Caucasians vs. Asians) due to oncogenic driver mutations specific to each race, exemplified by gefitinib / erlotinib. The molecular target drugs for lung cancer with anaplastic lymphoma kinase (ALK) gene translocation (the fusion gene, EML4-ALK) was approved, and those targeting lung cancers addicted ROS1, RET, and HER2 have been under development. Both identification and quantification of gatekeeper mutations need to be performed using lung cancer tissue specimens obtained from patients to improve the treatment for lung cancer patients: (1) identification and quantitation data of targeted mutated proteins, including investigation of mutation heterogeneity within a tissue; (2) exploratory mass spectrometry (MS)-based clinical proteogenomic analysis of mutated proteins; and also importantly (3) analysis of dynamic protein-protein interaction (PPI) networks of proteins significantly related to a subgroup of patients with lung cancer not only with good efficacy but also with acquired resistance. MS-based proteogenomics is a promising approach to directly capture mutated and fusion proteins expressed in a clinical sample. Technological developments are further expected, which will provide a powerful solution for the stratification of patients and drug discovery (Precision Medicine). PMID- 27686810 TI - Proteogenomics for the Study of Gastrointestinal Stromal Tumors. AB - Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. Gain-of-function mutations in KIT or platelet-derived growth factor receptor alpha (PDGFRA) drive most GISTs, and 85 % of GISTs also contain oncogenic mutations in one of two receptor tyrosine kinases. The advent of tyrosine kinase inhibitors has had a significant impact on the clinical practices for GISTs. However, tumors in more than 80 % of GIST patients acquire resistance against treatments with tyrosine kinase inhibitors; thus, driver mechanisms of secondary resistance as well as biomarkers for early detection of recurrence have been explored for better clinical outcomes. Proteomics is a versatile and straightforward approach to finding the molecular basis of malignancies as well as the innovative seeds for clinical applications. Comprehensive genome, epigenome, and transcriptome data have already been obtained and examined together in GISTs, and proteome data has a unique additional value in multi-omics studies. Various types of samples were examined using proteomics modalities in GIST, suggest the promising utility of proteomic approaches. PMID- 27686811 TI - Proteogenomics for the Comprehensive Analysis of Human Cellular and Serum Antibody Repertoires. AB - The vast repertoire of immunoglobulins produced by the immune system is a consequence of the huge amount of antigens to which we are exposed every day. The diversity of these immunoglobulins is due to different mechanisms (including VDJ recombination, somatic hypermutation, and antigen selection). Understanding how the immune system is capable of generating this diversity and which are the molecular bases of the composition of immunoglobulins are key challenges in the immunological field. During the last decades, several techniques have emerged as promising strategies to achieve these goals, but it is their combination which appears to be the fruitful solution for increasing the knowledge about human cellular and serum antibody repertoires.In this chapter, we address the diverse strategies focused on the analysis of immunoglobulin repertoires as well as the characterization of the genomic and peptide sequences. Moreover, the advantages of combining various -omics approaches are discussed through review different published studies, showing the benefits in clinical areas. PMID- 27686812 TI - Antibody-Based Proteomics. AB - Antibody-based proteomic approaches play an important role in high-throughput, multiplexed protein expression profiling in health and disease. These antibody based technologies will provide (miniaturized) set-ups capable of the simultaneously profiling of numerous proteins in a specific, sensitive, and rapid manner, targeting high- as well as low-abundant proteins, even in crude proteomes such as serum. The generated protein expression patterns, or proteomic snapshots, can then be transformed into proteomic maps, or detailed molecular fingerprints, revealing the composition of the target (sample) proteome at a molecular level. By using bioinformatics, candidate biomarker signatures can be deciphered and evaluated for clinical applicability. The approaches will provide unique opportunities for e.g. disease diagnostics, biomarker discovery, patient stratification, predicting disease recurrence, and evidence-based therapy selection. In this review, we describe the current status of the antibody-based proteomic approaches, focusing on antibody arrays. Furthermore, the current benefits and limitations of the approaches, as well as a set of selected key applications outlining the applicative potential will be discussed. PMID- 27686813 TI - Patterns of pre-hospital events and management of motorcycle-related injuries in a tropical setting. AB - This study sought to highlight associated factors and evaluate outcomes of motorcycle-related injuries (MCRI) among adults managed in a university teaching hospital in south-western Nigeria. The study was a cross-sectional descriptive study of 150 adult patients presenting with MCRI at the adult accident and emergency unit of the hospital. Information on the use of helmet, alcohol intake, number of pillion passengers, type of collision and time of arrival at hospital was collected. Patients were followed up and questionnaires were completed after discharge, referral or death. The male to female ratio was 4:1 with patients aged 20-29 years (n = 44, 29.3%) having the highest incidence of MCRI. Only 4 (2.7%) patients used helmet at the time of injury. About one-third of the patients (n = 59, 39.3%) arrived at the hospital within 1-6 hours after injury. The limbs were the most frequently involved site of injury, hence orthopaedic procedures constituted the highest number of interventions. Mortality rate was 10.7% (16 out of 150) with head injury being the leading cause. MCRI requires more emphasis on preventive measures. This will play a crucial role in the reduction of the associated morbidity and mortality. PMID- 27686814 TI - In vitro cytotoxic and genotoxic evaluation of peptides used in nuclear medicine (DOTATATE and Ubiquicidin29-41) in CHO-K1 cells. AB - Micronucleus (MN) assay constitutes a valuable surrogate to the chromosome aberration technique for in vitro testing of the genotoxicity of substances. As test substances, two peptidic compounds (DOTATATE and Ubiquicidin29-41) used in nuclear medicine, were tested for in vitro cytotoxicity and genotoxicity in CHO K1 cells. None of the compounds showed detectable cytotoxicity (0.5-7.3 ng/mL for DOTATATE and 0.3-4.5 ng/mL for UBI29-41), genotoxicity (0.72, 7.2 and 72.0 ng/ml for DOTATATE and 0.45, 4.5 and 45.0 ng/mL for UBI29-41) or cell cycle changes as compared to untreated controls at the concentrations tested. Statistical analysis showed good concordance between two independent analysts. The results corroborate the notion of the safety of the compounds and present improvements of the in vitro MN assay when performed in a pre-clinical trial context that increase the throughput of small-to-medium testing facilities as an alternative to high content screening systems. PMID- 27686818 TI - Shrinking the food-print: A qualitative study into consumer perceptions, experiences and attitudes towards healthy and environmentally friendly food behaviours. AB - Internationally, there is increasing recognition of the importance of multilevel policies and actions that address healthy and environmentally friendly food behaviours. However it is not yet clear which actions are most suitable to support consumers to adopt both behaviours concurrently. To this end, we undertook a qualitative study to assess consumer perceptions, experiences and attitudes towards healthy and environmentally friendly foods and four target behaviours: reducing overconsumption of food beyond energy needs, reducing consumption of low-nutrient energy dense foods, eating less animal- and more plant-derived foods, and reducing food waste. Online in-depth interviews were held with 29 Australian food shoppers representing different levels of involvement with health and environment in daily food choices. The results indicate that compared to health, the relationship between food and the environment is rarely considered by consumers. The four target food behaviours were primarily associated and motivated by an impact on health, except for not wasting foods. Participants had the most positive attitude and highest motivation for eating less processed and packaged foods, mostly to avoid excessive packaging and 'chemicals' in foods. This was followed by the behaviours reducing food waste and overconsumption. Conversely, there was a predominantly negative attitude towards, and low motivation for, eating less animal-derived products and more plant based foods. Overall, consumers found a joined concept of healthy and environmentally friendly foods an acceptable idea. We recommend that health should remain the overarching principle for policies and actions concerned with shifting consumer behaviours, as this personal benefit appears to have a greater potential to support behaviour change. Future consumer focused work could pay attention to framing behavioural messages, providing intermediate behavioural goals, and a multiple target approach to change habitual behaviours. PMID- 27686819 TI - Yogurt's flexible image during its rise in popularity in post-war Belgium. AB - The consumption of yogurt in Western countries has risen for over a century, first slowly, then more rapidly. The purpose of the present study was to investigate this prolonged phase of growth, by examining the popularity and the projected image of yogurt. A particular focus was on the way these aspects were reflected in consumption patterns and media representations. The data showed how during its period of rapid popularization, yogurt's visibility in the media greatly increased. It was concluded that the product's image was highly flexible in post-war decades, evidenced by the multi-pronged approach taken by marketers. Yogurt was not only advertised as both tasty and healthy, but also as natural and convenient, a strategy that appears to have been informed by consumers' preferences and existing cultural values. This demonstrates how a high degree of product differentiation and diversification during a product's growth stage can result in a heterogeneous image, allowing for a broad range of marketing strategies. PMID- 27686821 TI - Release of synthetic microplastic plastic fibres from domestic washing machines: Effects of fabric type and washing conditions. AB - Washing clothes made from synthetic materials has been identified as a potentially important source of microscopic fibres to the environment. This study examined the release of fibres from polyester, polyester-cotton blend and acrylic fabrics. These fabrics were laundered under various conditions of temperature, detergent and conditioner. Fibres from waste effluent were examined and the mass, abundance and fibre size compared between treatments. Average fibre size ranged between 11.9 and 17.7MUm in diameter, and 5.0 and 7.8mm in length. Polyester cotton fabric consistently shed significantly fewer fibres than either polyester or acrylic. However, fibre release varied according to wash treatment with various complex interactions. We estimate over 700,000 fibres could be released from an average 6kg wash load of acrylic fabric. As fibres have been reported in effluent from sewage treatment plants, our data indicates fibres released by washing of clothing could be an important source of microplastics to aquatic habitats.

AB - Comprising of two experiments, this study assessed the metabolic, endocrine and appetite-related responses to acute and chronic milk consumption in adolescent males (15-18 y). Eleven adolescents [mean +/- SD age: 16.5 +/- 0.9 y; BMI: 23.3 +/- 3.3 kg/m2] participated in the acute experiment and completed two laboratory visits (milk vs. fruit-juice) in a randomized crossover design, separated by 7-d. Seventeen adolescents [age: 16.1 +/- 0.9 y; BMI: 21.8 +/- 3.7 kg/m2] completed the chronic experiment. For the chronic experiment, a parallel design with two groups was used. Participants were randomly allocated and consumed milk (n = 9) or fruit-juice (n = 8) for 28-d, completing laboratory visits on the first (baseline, day-0) and last day (follow-up, day-28) of the intervention phase. On laboratory visits (for both experiments), measures of appetite, metabolism and endocrine responses were assessed at regular intervals. In addition, eating behavior was quantified by ad libitum assessment under laboratory conditions and in the free-living environment by weighed food record. Acute milk intake stimulated glucagon (P = 0.027 [16.8 pg mL; 95% CI: 2.4, 31.3]) and reduced ad libitum energy intake relative to fruit-juice (P = 0.048 [-651.3 kJ; 95% CI: 1294.1, -8.6]), but was comparable in the free-living environment. Chronic milk intake reduced free-living energy intake at the follow-up visit compared to baseline (P = 0.013 [-1910.9 kJ; 95% CI: -554.6, -3267.2]), whereas the opposite was apparent for fruit-juice. Relative to baseline, chronic milk intake increased the insulin response to both breakfast (P = 0.031) and mid-morning milk consumption (P = 0.050) whilst attenuating blood glucose (P = 0.025). Together, these findings suggest milk consumption impacts favorably on eating behavior in adolescent males, potentially through integrated endocrine responses.

We performed five net-tows and collected 44 pieces of plastic. Total particle counts of the entire water column, which is free of vertical mixing, were computed using the surface concentration (particle count per unit seawater volume) of microplastics, wind speed, and significant wave height during the observation period. Total particle counts at two stations near Antarctica were estimated to be in the order of 100,000pieceskm-2. PMID- 27686823 TI - Marine copepod cytochrome P450 genes and their applications for molecular ecotoxicological studies in response to oil pollution. AB - Recently, accidental spills of heavy oil have caused adverse effects in marine organisms. Oil pollution can induce damages on development and reproduction, linking with detrimental effects on diverse molecular levels of genes and proteins in plankton and fish. However, most information was mainly focused on marine vertebrates and consequently, limited information was available in marine invertebrates. Furthermore, there is still a lack of knowledge bridging in vivo endpoints with the functional regulation of cytochrome P450 (CYP) genes in response to oil spill pollution in marine invertebrates. In this paper, adverse effects of oil spill pollution in marine invertebrates are summarized with the importance of CYP genes as a potential biomarker, applying for environmental monitoring to detect oil spill using marine copepods.

PMID- 27686826 TI - A Modified Delphi Study to Identify Factors Associated With Clinical Deterioration in Hospitalized Children. AB - OBJECTIVE: Hospitalized children who are admitted to the inpatient ward can deteriorate and require unplanned transfer to the PICU. Studies designed to validate early warning scoring systems have focused mainly on abnormalities in vital signs in patients admitted to the inpatient ward. The objective of this study was to determine the patient and system factors that experienced clinicians think are associated with progression to critical illness in hospitalized children. METHODS: We conducted a modified Delphi study with 3 iterations, administered electronically. The expert panel consisted of 11 physician and nonphysician health care providers from hospitals in Canada and the United States. RESULTS: Consensus was reached that 21 of the 57 factors presented are associated with clinical deterioration in hospitalized children. The final list of variables includes patient characteristics, signs and symptoms in the emergency department, emergency department management, and system factors. CONCLUSIONS: We generated a list of variables that can be used in future prospective studies to determine if they are predictors of clinical deterioration on the inpatient ward.

AB - PURPOSE: Metastasis is the leading cause of death for a majority of cancer patients, and thus the need to understand the biology of metastasis becomes increasingly acute. When metastasis is initiated in tumor progression remains obscure. Better understanding of mechanisms regulating acquisition of metastatic ability in tumor cells will provide novel therapeutic targets and prevention of metastasis in clinics accompanied with the treatment of the primary tumor might be helpful in reducing metastasis-related mortality. METHODS: A literature search was performed in multiple electronic databases. Research papers from clinical reports to experimental studies on metastasis were analyzed. RESULTS: The article discusses tumor heterogeneity and genomic instability in the context of metastasis and tumor cell dissemination. And then we review biological mechanism of metastasis at an early stage in both intracellular (CSCs and CTCs) and extracellular (microenvironment) context. Finally, current development of anti metastatic therapies is summarized. CONCLUSIONS: Metastasis could be initiated at an early point of tumor progression. Therefore, early intervention on metastasis should be applied among cancer patients in clinical settings.

AB - Nano-particles (NPs) are used in industrial and biomedical fields such as cosmetics, food additives and biosensors. Beside their favorable properties, nanoparticles are responsible for toxic effects. Local adverse effects and/or systemic toxicity are described with nanoparticle delivery to target organs of the human body. Animal studies provide evidence for the aforementioned toxicity. Cardiac function is a specific target of nanoparticles. Thus, reviewing the current bibliography on cardiotoxicity of nanoparticles and specifically of titanium, zinc, silver, carbon, silica and iron oxide nano-materials is the aim of this study. PMID- 27686831 TI - Glabridin-induced vasorelaxation: Evidence for a role of BKCa channels and cyclic GMP. AB - BACKGROUND AND PURPOSE: Glabridin is a major flavonoid in Glycyrrhiza glabra (licorice) root, a traditional Asian medicine. Glabridin is reported to have anti atherogenic, anti-inflammatory and anti-nephritic properties; however its effects on vascular tone remain unexplored. EXPERIMENTAL APPROACH: We examined the effect of glabridin on rat main mesenteric artery using isometric myography and also ELISA to measure cGMP levels. KEY RESULTS: Glabridin (30MUM) relaxed arteries pre constricted with the thromboxane A2 analog U46619 (0.2MUM) by ~60% in an endothelium-independent manner. Relaxation to 30MUM glabridin was abolished by the guanylate cyclase inhibitor 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (1MUM) and by the BKCa channel blocker tetraethyammonium (1mM) but was unaffected by the estrogen receptor antagonist ICI182780. The concentration-response curve to glabridin (0.1 to 30MUM) was downshifted by the KATP channel blocker glibenclamide (10MUM), the KV channel blocker 4-aminopyridine (300MUM), and the KIR blocker BaCl2 (30MUM). In U46619-contracted arteries partially relaxed by 0.1MUM sodium nitroprusside, application of 10 and 30nM glabridin caused additional vasorelaxation. Glabridin (30MUM) approximately doubled tissue [cyclic GMP]. Application of the phosphodiesterase inhibitor isobutylmethylxanthine caused a much larger rise in [cyclic GMP], and glabridin failed to cause vasorelaxation or a further rise in [cGMP] when co-applied with IBMX. CONCLUSIONS AND IMPLICATIONS: Vasorelaxation to glabridin is dependent on the opening of K+ channels, particularly BKCa, probably caused by a rise in cellular [cyclic GMP] owing to phosphodiesterase inhibition. In the presence of sodium nitroprusside an effect of glabridin is observed at nM concentrations, similar those measured in plasma following human ingestion of licorice flavonoid oil. PMID- 27686833 TI - Long-term follow-up of Japanese encephalitis chimeric virus vaccine: Immune responses in children. AB - BACKGROUND: A single dose of live attenuated Japanese encephalitis chimeric virus vaccine (JE-CV) was shown to be immunogenic and well tolerated when given either as a booster to formalin-inactivated Japanese encephalitis (JE)-vaccine (mouse brain-derived vaccine [MBDV])-primed 2-5-year-olds, or as a primary vaccination to JE-vaccine-naive 12-24-month-old toddlers in Thailand. A 5-year follow-up assessment of immune response persistence over time was conducted. METHODS: Four additional visits (at 2, 3, 4, and 5years) for immunologic assessments were added to the original 12-month open-label crossover study, in which 100 healthy children aged 2-5years with a history of two-dose primary vaccination with MBDV (according to the Thai Expanded Program for Immunization schedule), and 200 healthy JE-vaccine-naive 12-24-month-old toddlers, were randomized 1:1 to receive JE-CV, containing ?4 log10 plaque forming units, 1month before or after hepatitis A control vaccine. RESULTS: In MBDV-primed 2-5-year-olds (n=78), the immune response to the JE-CV vaccine persisted up to at least 5years after vaccination with a single dose of JE-CV, with all (n=78) children seroprotected at the year 5 visit (geometric mean titers [GMT]: 2521/dil). There was no decrease of seroprotection rate over time (100% at 6months post-vaccination and 96.8% (90.3 98.9) at 5yearspost-vaccination). In JE-vaccine-naive toddlers, a protective immune response persisted up to at least 5years in 58.8% (50.9-66.4) after a single-dose administration of JE-CV (GMT 26.71/dil; sensitivity analysis). CONCLUSIONS: A single-dose of JE-CV as a booster following MBDV administration provided long-lasting immunity. In JE-vaccine-naive toddlers, despite relatively high seroprotection rates persisting over time, a subsequent booster dose is recommended following a JE-CV primary vaccination for long-term protection. This study was registered on www.clinicaltrials.gov (NCT00621764). PMID- 27686834 TI - Integrating pharmacies into public health program planning for pandemic influenza vaccine response. AB - BACKGROUND: During an influenza pandemic, to achieve early and rapid vaccination coverage and maximize the benefit of an immunization campaign, partnerships between public health agencies and vaccine providers are essential. Immunizing pharmacists represent an important group for expanding access to pandemic vaccination. However, little is known about nationwide coordination between public health programs and pharmacies for pandemic vaccine response planning. METHODS: To assess relationships and planning activities between public health programs and pharmacies, we analyzed data from Centers for Disease Control and Prevention assessments of jurisdictions that received immunization and emergency preparedness funding from 2012 to 2015. RESULTS: Forty-seven (88.7%) of 53 jurisdictions reported including pharmacies in pandemic vaccine distribution plans, 24 (45.3%) had processes to recruit pharmacists to vaccinate, and 16 (30.8%) of 52 established formal relationships with pharmacies. Most jurisdictions plan to allocate less than 10% of pandemic vaccine supply to pharmacies. DISCUSSION: While most jurisdictions plan to include pharmacies as pandemic vaccine providers, work is needed to establish formalized agreements between public health departments and pharmacies to improve pandemic preparedness coordination and ensure that vaccinating pharmacists are fully utilized during a pandemic. PMID- 27686835 TI - Equity in disease prevention: Vaccines for the older adults - a national workshop, Australia 2014. AB - On the 20th June, 2014 the National Health and Medical Research Council's Centre for Research Excellence in Population Health "Immunisation in under Studied and Special Risk Populations", in collaboration with the Public Health Association of Australia, hosted a workshop "Equity in disease prevention: vaccines for the older adults". The workshop featured international and national speakers on ageing and vaccinology. The workshop was attended by health service providers, stakeholders in immunisation, ageing, primary care, researchers, government and non-government organisations, community representatives, and advocacy groups. The aims of the workshop were to: provide an update on the latest evidence around immunisation for the older adults; address barriers for prevention of infection in the older adults; and identify immunisation needs of these groups and provide recommendations to inform policy. There is a gap in immunisation coverage of funded vaccines between adults and infants. The workshop reviewed provider misconceptions, lack of Randomised Control Trials (RCT) and cost-effectiveness data in the frail elderly, loss of autonomy, value judgements and ageism in health care and the need for an adult vaccination register. Workshop recommendations included recognising the right of elderly people to prevention, the need for promotion in the community and amongst healthcare workers of the high burden of vaccine preventable diseases and the need to achieve high levels of vaccination coverage, in older adults and in health workers involved in their care. Research into new vaccine strategies for older adults which address poor coverage, provider attitudes and immunosenescence is a priority. A well designed national register for tracking vaccinations in older adults is a vital and basic requirement for a successful adult immunisation program. Eliminating financial barriers, by addressing inequities in the mechanisms for funding and subsidising vaccines for the older adults compared to those for children, is important to improve equity of access and vaccination coverage. Vaccination coverage rates should be included in quality indicators of care in residential aged care for older adults. Vaccination is key to healthy ageing, and there is a need to focus on reducing the immunisation gap between adults and children.

PMID- 27686836 TI - The innate immune response to RSV: Advances in our understanding of critical viral and host factors. AB - Respiratory syncytial virus (RSV) causes mild to severe respiratory illness in humans and is a major cause of hospitalizations of infants and the elderly. Both the innate and the adaptive immune responses contribute to the control of RSV infection, but despite successful viral clearance, protective immunity against RSV re-infection is usually suboptimal and infections recur. Poor understanding of the mechanisms limiting the induction of long-lasting immunity has delayed the development of an effective vaccine. The innate immune response plays a critical role in driving the development of adaptive immunity and is thus a crucial determinant of the infection outcome. Advances in recent years have improved our understanding of cellular and viral factors that influence the onset and quality of the innate immune response to RSV. These advances include the identification of a complex system of cellular sensors that mediate RSV detection and stimulate transcriptome changes that lead to virus control and the discovery that cell stress and apoptosis participate in the control of RSV infection. In addition, it was recently demonstrated that defective viral genomes (DVGs) generated during RSV replication are the primary inducers of the innate immune response. Newly discovered host pathways involved in the innate response to RSV, together with the potential generation of DVG-derived oligonucleotides, present various novel opportunities for the design of vaccine adjuvants able to induce a protective response against RSV and similar viruses. PMID- 27686839 TI - Betterment, undermining, support and distortion: A heuristic model for the analysis of pressure on evaluators. AB - Evaluations can only serve as a neutral evidence base for policy decision-making as long as they have not been altered along non-scientific criteria. Studies show that evaluators are repeatedly put under pressure to deliver results in line with given expectations. The study of pressure and influence to misrepresent findings is hence an important research strand for the development of evaluation praxis. A conceptual challenge in the area of evaluation ethics research is the fact that pressure can be not only negative, but also positive. We develop a heuristic model of influence on evaluations that does justice to this ambivalence of influence: the BUSD-model (betterment, undermining, support, distortion). The model is based on the distinction of two dimensions, namely 'explicitness of pressure' and 'direction of influence'. We demonstrate how the model can be applied to understand pressure and offer a practical tool to distinguish positive from negative influence in the form of three so-called differentiators (awareness, accordance, intention). The differentiators comprise a practical component by assisting evaluators who are confronted with influence. PMID- 27686838 TI - CCL18 synergises with high concentrations of glucose in stimulating fibronectin production in human renal tubuloepithelial cells. AB - BACKGROUND: Diabetic nephropathy is the leading cause of end stage kidney disease worldwide. The pathogenesis of this disease remains elusive and multiple factors have been implicated. These include the effects of hyperglycaemia, haemodynamic and metabolic factors, and an inflammatory process that stimulates cellular signalling pathways leading to disease progression and severe fibrosis. Fibronectin (Fn) is an important protein of the extracellular matrix that is essential in fibrosis and its presence in increased amounts has been identified in the kidney in diabetic nephropathy. METHODS: Proximal tubuloepithelial (HK-2) cells were stimulated with high glucose (30 mM D-glucose) or glycated albumin (500 MUg/mmol) + 4 mM D-glucose or their controls, Mannitol (26 mM + 4 mM D glucose) and 4 mM D-glucose, respectively. Following 48 h of stimulation the supernatant was collected and MTT [3-(4,5-dimethylthiazole-2,5 diphenyltetrazolium bromide] assay performed to assess cell viability. HK-2 cells were also stimulated in the above environments with recombinant CCL18 (rCCL18) or MCP-1 (rMCP-1) for 48 h with quantification of Fn levels using ELISA. RESULTS: Co stimulation of HK-2 cells with high concentrations of glucose and rCCL18 significantly increased Fn (p < 0.001), in comparison to high concentrations of glucose alone. HK-2 cells stimulated with glycated albumin consistently produced Fn and this did not alter following co-stimulation with rCCL18 or rMCP-1. CONCLUSION: This study demonstrates how stimulation with a specific chemokine CCL18 in high glucose upregulates the production of Fn from proximal tubuloepithelial cells. This may be relevant to the development of renal fibrosis in diabetic nephropathy. PMID- 27686840 TI - Amniopatch treatment of iatrogenic preterm premature rupture of membranes (iPPROM) after fetoscopic laser surgery for twin-twin transfusion syndrome. AB - OBJECTIVES: Amniopatch is a proposed treatment of iatrogenic preterm premature rupture of membranes (iPPROM). We studied characteristics associated with successful amniopatch treatment of iPPROM after fetoscopic laser surgery for twin twin transfusion syndrome. METHODS: Patients with iPPROM within 15 days of laser surgery treated with an amniopatch were studied. Factors associated with amniopatch success (i.e. cessation of leakage with normalization of amniotic fluid volume) were tested univariately and in multivariate logistic regression models. Continuous variables are expressed as median (range). RESULTS: Of 1124 patients undergoing laser surgery, 19 (1.7%) had iPPROM and subsequent amniopatch. Twelve (63.2%) were successful. Latency in days from iPPROM to delivery was greater in the successful group (114.0 [87.0-141.0]) versus (44.0 [3.9-88.0], p = 0.0005), which translated into greater gestational age (GA) (weeks) at delivery (35.1 [30.9-39.4] versus 28.1 [22.0-31.0], p = 0.0005). The 30-day survival of the affected recipient twin was improved (100% versus 57.1%, p = 0.0361). After multivariate testing, GA < 20 weeks at the time of the amniopatch placement was the only variable that remained associated with successful sealing of the membranes. CONCLUSIONS: Treatment of iPPROM via amniopatch was successful in almost two-thirds of cases and was associated with higher GA at delivery and improved perinatal survival. PMID- 27686841 TI - Women's views about the timing of birth. AB - BACKGROUND: Estimated date of birth (EDB) is used to guide the care provided to women during pregnancy and birth, although its imprecision is recognised. Alternatives to the EDB have been suggested for use with women however their attitudes to timing of birth information have not been examined. AIMS: To explore women's expectations of giving birth on or near their EDB, and their attitudes to alternative estimates for timing of birth. METHODS: A survey of pregnant women attending four public hospitals in Sydney, Australia, between July and December 2012. RESULTS: Among 769 surveyed women, 42% expected to birth before their due date, 16% after the due date, 15% within a day or so of the due date, and 27% had no expectations. Nulliparous women were more likely to expect to give birth before their due date. Women in the earlier stages of pregnancy were more likely to have no expectations or to expect to birth before the EDB while women in later pregnancy were more likely to expect birth after their due date. For timing of birth information, only 30% of women preferred an EDB; the remainder favoured other options. CONCLUSIONS: Most women understood the EDB is imprecise. The majority of women expressed a preference for timing of birth information in a format other than an EDB. In support of woman-centred care, clinicians should consider discussing other options for estimated timing of birth information with the women in their care. PMID- 27686842 TI - Can antenatal classes reduce the rate of cesarean section in southern Italy? AB - BACKGROUND: Among European Countries, Italy has the highest rate of cesarean section (36.8%), and in the Campania region this rate reaches 60.0%. QUESTION: We conducted a retrospective cohort study to evaluate whether participation in antenatal classes during pregnancy reduces the rate of cesarean delivery in southern Italy. METHODS: We selected three local health authorities, with the lowest, the highest, and an intermediate rate of cesarean delivery. The study included 1893 mothers who brought their children for vaccination and were interviewed about their participation in antenatal classes and their obstetric history. FINDINGS: The main causes of cesarean section given in the interview were clinical indications (61.0%), previous cesarean section (31.0%) and woman's request (8.0%). When we excluded emergency cesarean delivery, we found a moderate association between participation in antenatal classes and cesarean section reduction (relative risk=1.27; 95% CI=1.08-1.49; in percentage values from 49.3% to 38.8%). Private hospitals and the two local health authorities with higher baseline rates of cesarean section showed an enhanced reduction of these rates. CONCLUSION: Our paper shows moderate efficacy of antenatal classes, which reduced the occurrence of cesarean section by about 10%. However, the cesarean section rate remained high. As it is possible that different classes have a different level of efficacy, a further study on a standardized model of an antenatal classes is in progress, to assess its efficacy in term of cesarean section reduction, with the purpose of its widespread implementation to the whole region. PMID- 27686843 TI - Does neuroinflammation drive the relationship between tau hyperphosphorylation and dementia development following traumatic brain injury? AB - A history of traumatic brain injury (TBI) is linked to an increased risk for the later development of dementia. This encompasses a variety of neurodegenerative diseases including Alzheimer's Disease (AD) and chronic traumatic encephalopathy (CTE), with AD linked to history of moderate-severe TBI and CTE to a history of repeated concussion. Of note, both AD and CTE are characterized by the abnormal accumulation of hyperphosphorylated tau aggregates, which are thought to play an important role in the development of neurodegeneration. Hyperphosphorylation of tau leads to destabilization of microtubules, interrupting axonal transport, whilst tau aggregates are associated with synaptic dysfunction. The exact mechanisms via which TBI may promote the later tauopathy and its role in the later development of dementia are yet to be fully determined. Following TBI, it is proposed that axonal injury may provide the initial perturbation of tau, by promoting its dissociation from microtubules, facilitating its phosphorylation and aggregation. Altered tau dynamics may then be exacerbated by the chronic persistent inflammatory response that has been shown to persist for decades following the initial impact. Importantly, immune activation has been shown to play a role in accelerating disease progression in other tauopathies, with pro inflammatory cytokines, like IL-1beta, shown to activate kinases that promote tau hyperphosphorylation. Thus, targeting the inflammatory response in the sub-acute phase following TBI may represent a promising target to halt the alterations in tau dynamics that may precede overt neurodegeneration and later development of dementia.

PMID- 27686844 TI - A survey of neuroimmune changes in pregnant and postpartum female rats. AB - During pregnancy and the postpartum period, the adult female brain is remarkably plastic exhibiting modifications of neurons, astrocytes and oligodendrocytes. However, little is known about how microglia, the brain's innate immune cells, are altered during this time. In the current studies, microglial density, number and morphological phenotype were analyzed within multiple regions of the maternal brain that are known to show neural plasticity during the peripartum period and/or regulate peripartum behavioral changes. Our results show a significant reduction in microglial density during late pregnancy and the early-mid postpartum period in the basolateral amygdala, medial prefrontal cortex, nucleus accumbens shell and dorsal hippocampus. In addition, microglia numbers were reduced postpartum in all four brain regions, and these reductions occurred primarily in microglia with a thin, ramified morphology. Across the various measures, microglia in the motor cortex were unaffected by reproductive status. The peripartum decrease in microglia may be a consequence of reduced proliferation as there were fewer numbers of proliferating microglia, and no changes in apoptotic microglia, in the postpartum hippocampus. Finally, hippocampal concentrations of the cytokines interleukin (IL)-6 and IL-10 were increased postpartum. Together, these data point to a shift in the maternal neuroimmune environment during the peripartum period that could contribute to neural and behavioral plasticity occurring during the transition to motherhood. PMID- 27686847 TI - Selected reaction monitoring mass spectrometry for relative quantification of proteins involved in cellular life and death processes. AB - Monitoring of proteins involved in cellular life and death processes is of high scientific interest since it permits the elucidation of functional changes in a variety of diseases. In this study, we have developed a nanoLC-MS/MS assay for the simultaneous detection and quantification of 24 selected proteins that are known to be important for cellular homeostasis. The Selected Reaction Monitoring (SRM) assay applies heavy-labeled peptide analogues for the relative quantification of proteins with central functions in cellular stress and metabolism, including many mitochondrial proteins. The assay includes proteins involved in the quality control of mitochondrial proteins, oxidative stress, respiratory chain, and fatty acid degradation, as well as the cytosolic glyceraldehyde 3-phosphate dehydrogenase, lactate dehydrogenase and ribosomal proteins. The assay can thus quantitate the balance between mitochondrial and cytosolic pathways, which is relevant in many disease states, and can be studied by comparing patient and control samples. The measured validation parameters showed satisfactory results for the proteins included in the analysis. The linear range of the monitored proteins was 0.01-20nM, with a median precision of less than 10%. The assay performed well in monitoring proteins in both cultured human skin fibroblast cells as well as in isolated peripheral blood mononuclear cells. We therefore believe that this assay is applicable for the study of cellular stress response in various types of cell defects and disease states. PMID- 27686849 TI - Redox signaling and oxidative stress: Cross talk with TNF-related apoptosis inducing ligand activity. AB - Redox regulation plays a key role in several physiopathological contexts and free radicals, from nitric oxide and superoxide anion up to other forms of reactive oxygen species (ROS), have been demonstrated to be involved in different biological and regulatory processes. The data reported in the current literature describe a link between ROS, inflammation and programmed cell death that is attracting interest as new pathways to be explored and targeted for therapeutic purposes. In this light, there is also growing attention to the involvement of this link in the activity of the TNF-related apoptosis inducing ligand (TRAIL). TRAIL is a member of the TNF ligands super family able to mediate multiple intracellular signals, with the potential to lead to a range of biological effects in different cell types. In particular, the hallmark of TRAIL is the ability to induce selective apoptosis in transformed cells leaving normal cells almost unaffected and this feature has already opened the door to several clinical studies for cancer treatment. Moreover, TRAIL plays a role in several physiological and pathological processes of both innate and adaptive immune systems and of the cardiovascular context, with a strong clinical potential. Nonetheless, several issues still need to be clarified about the signaling mediated by TRAIL to gain deeper insight into its therapeutic potential. In this light, the aim of this review is to summarize the main preclinical evidences about the interplay between TRAIL and redox signaling, with particular emphasis to the implications in vascular physiopathology and cancer.

AB - Among several types of tumor, lung cancer is considered one of the most fatal and still the main cause of cancer-related deaths. Although chemotherapeutic agents can improve survival and quality of life compared with symptomatic treatment, cancers usually still progress after chemotherapy and are often aggravated by serious side effects. In the last few years there has been a growing interest in immunotherapy for lung cancer based on promising preliminary results in achieving meaningful and durable treatments responses with minimal manageable toxicity. This article is divided into two parts, the first part discusses the role of human immune system in controlling and eradicating cancer and the mechanisms of immune response evasion by tumor. The second part reviews the recent progress made in immunotherapy for lung cancer with results from trials evaluating therapeutic vaccines in addition to immune checkpoint blockade, specifically cytotoxic T lymphocyte associated protein 4, programmed death receptor 1 pathway, using monoclonal antibodies. PMID- 27686851 TI - Executable medical guidelines with Arden Syntax-Applications in dermatology and obstetrics. AB - INTRODUCTION: Clinical decision support systems (CDSSs) are being developed to assist physicians in processing extensive data and new knowledge based on recent scientific advances. Structured medical knowledge in the form of clinical alerts or reminder rules, decision trees or tables, clinical protocols or practice guidelines, score algorithms, and others, constitute the core of CDSSs. Several medical knowledge representation and guideline languages have been developed for the formal computerized definition of such knowledge. One of these languages is Arden Syntax for Medical Logic Systems, an International Health Level Seven (HL7) standard whose development started in 1989. Its latest version is 2.10, which was presented in 2014. In the present report we discuss Arden Syntax as a modern medical knowledge representation and processing language, and show that this language is not only well suited to define clinical alerts, reminders, and recommendations, but can also be used to implement and process computerized medical practice guidelines. METHODS: This section describes how contemporary software such as Java, server software, web-services, XML, is used to implement CDSSs based on Arden Syntax. Special emphasis is given to clinical decision support (CDS) that employs practice guidelines as its clinical knowledge base. RESULTS: Two guideline-based applications using Arden Syntax for medical knowledge representation and processing were developed. The first is a software platform for implementing practice guidelines from dermatology. This application employs fuzzy set theory and logic to represent linguistic and propositional uncertainty in medical data, knowledge, and conclusions. The second application implements a reminder system based on clinically published standard operating procedures in obstetrics to prevent deviations from state-of-the-art care. A to do list with necessary actions specifically tailored to the gestational week/labor/delivery is generated. DISCUSSION: Today, with the latest versions of Arden Syntax and the application of contemporary software development methods, Arden Syntax has become a powerful and versatile medical knowledge representation and processing language, well suited to implement a large range of CDSSs, including clinical-practice-guideline-based CDSSs. Moreover, such CDS is provided and can be shared as a service by different medical institutions, redefining the sharing of medical knowledge. Arden Syntax is also highly flexible and provides developers the freedom to use up-to-date software design and programming patterns for external patient data access. PMID- 27686852 TI - Clinical Course of Two Children with Unstable Hemoglobins: The Effect of Hydroxyurea Therapy. AB - Case reports on the effect of hydroxyurea (HU) therapy for unstable hemoglobins (Hbs) are sparse; only three adult cases have been reported. We report for the first time on the effect of HU therapy in children carrying unstable Hbs. The first case concerns a female child with a familial history of chronic hemolytic anemia. She was diagnosed with Hb Volga (HBB: c.83C>A) at the age of 7 months. At age 6, treatment options were reconsidered due to increasing fatigue and decreasing Hb concentration. The second case also concerns a female child with chronic hemolytic anemia and icterus since the age of 5. She was diagnosed with Hb Koln (HBB: c.295G>A) at the age of 9. At age 10, treatment options were reconsidered due to decreased general condition and poor school performance. Both children were started on HU therapy. The child with Hb Volga showed reduced clinical symptoms and increased average Hb concentrations. She has been on HU therapy for over 7 years at preparation of this manuscript. The child with Hb Koln showed decreasing Hb concentrations upon start of therapy; clinical symptoms did not improve. Therapy was discontinued after 31/2 months. The Hb Volga case report suggests that HU therapy could improve clinical symptoms in some patients with unstable Hbs. Based on these and previously published cases, it was speculated that response can be predicted by the percentage of Hb F and reticulocyte counts. PMID- 27686853 TI - Mixed Micelles Loaded with Bile Salt: An Approach to Enhance Intestinal Transport of the BCS Class III Drug Cefotaxime in Rats. AB - BACKGROUND AND OBJECTIVES: Cefotaxime is a class III drug according to the Biopharmaceutical Classification System due to low intestinal permeability based on poor oral bioavailability. Bile salt compounds have been shown to be effective additive for drug permeation through several biological membranes. The main purpose of this study was to investigate the ability of a mixed micelles made of phosphatidylcholine, sodium deoxycholate, and loaded with a cefotaxime 3alpha,7alpha-dihydroxy-12-keto-5beta-cholanate complex to enhance the oral bioavailability of cefotaxime in rats. METHODS: Thin-film hydration method was used to prepare cefotaxime-loaded mixed micelles using different bile salt concentrations (0.87-25 mM of sodium deoxycholate). Overall, micelle sizes ranging from 86.9 to 155.6 nm were produced with negative zeta potential values from -15.9 to -19.5 mV and drug loading from 10.5 to 18.9 %. The oral bioavailability of cefotaxime in mixed micellar formulation was assessed and the pharmacokinetic parameters were compared with cefotaxime-3alpha,7alpha-dihydroxy 12-keto-5beta-cholanate complex and cefotaxime aqueous solution. 24 Male Wistar rats were randomly allocated into four groups (n = 6, per group) to receive the following: (1) a single intravenous dose of cefotaxime (25 mg/kg) in sterilized normal saline solution for injection; (2) a single oral dose of mixed micelles (100 mg/kg of cefotaxime) in phosphate buffered saline administered by oral gavage; (3) a single oral dose of cefotaxime-3alpha,7alpha-dihydroxy-12-keto 5beta-cholanate complex (100 mg/kg of cefotaxime) in phosphate buffered saline administered by oral gavage; (4) a single oral dose of free cefotaxime (100 mg/kg) in aqueous solution administered by oral gavage. Blood samples were collected for up to 24 h and cefotaxime analyzed using a validated HPLC assay. RESULTS: Pharmacokinetic data showed that the oral bioavailability of cefotaxime in mixed micelles was found to be 4.91 % higher compared to the cefotaxime in aqueous solution (1.30 %). Maximum concentration (C max) of cefotaxime in mixed micellar formulation was higher (1.08 +/- 0.1 ug/ml) compared to the cefotaxime 3alpha,7alpha-dihydroxy-12-keto-5beta-cholanate complex (0.69 +/- 0.1 ug/ml) and cefotaxime in aqueous solution (0.52 +/- 0.1 ug/ml). Similarly, the mean values for area under the plasma concentration-time curve extrapolated to infinity (AUC0 infinity) of cefotaxime in the mixed micellar formulation was higher (3.89 +/- 0.9 MUg.h/mL) compared to the cefotaxime-3alpha,7alpha-dihydroxy-12-keto-5beta cholanate complex (1.52 +/- 0.2 MUg.h/mL) and cefotaxime in aqueous solution (1.03 +/- 0.4 MUg.h/mL), respectively. CONCLUSION: The mixed micellar formulation was able to increase the oral bioavailability of the BCS Class III drug cefotaxime up to fourfold by enhancing drug permeation through the mucosal membrane of the small intestine. PMID- 27686854 TI - Ghrelin and adipose-derived mesenchymal stromal cells improve nerve regeneration in a rat model of epsilon-caprolactone conduit reconstruction. AB - OBJECTIVE: Attempts have been made to improve nerve conduits in peripheral nerve reconstruction. We investigated the potential therapeutic effect of adipose derived mesenchymal cells (ASCs) and ghrelin (GHR), a neuropeptide with neuroprotective, trophic, and developmental regulatory actions, on peripheral nerve regeneration in a model of severe nerve injury repaired with nerve conduits. MATERIAL AND METHODS: The right sciatic nerves of 24 male Wistar rats were 10-mm transected unilaterally and repaired with Dl-lactic-epsilon caprolactone conduits. Rats were then treated locally with saline, ASCs, or GHR. At 12 weeks post-surgery, we assessed limb function by measuring ankle stance angle and percentage muscle mass reduction and evaluated the histopathology, immunohistochemistry, ultrastructure, and morphometry of myelinated fibers. MAIN RESULTS: Rats receiving GHR or ASCs showed no significant increased functional recovery in ankle stance angle (p=0.372) but a higher nerve area (p=0.015), myelin area (p=0.046) and number of myelinated fibers (p=0.012) in the middle and distal segments of operated sciatic nerves in comparison to saline-treated control animals. CONCLUSION: These results suggest that utilization of ghrelin or ASCs may improve nerve regeneration using Dl-lactic-epsilon-caprolactone conduits. PMID- 27686856 TI - Tunisian tomato by-products, as a potential source of natural bioactive compounds. AB - Consumption of tomato and tomato products is positively related to the reduction in cardiovascular disease and several types of cancer, thanks to the presence of natural compounds, such as antioxidants. Peels and seeds fractions of tomato, collected after industrial processing in Tunisian industries, were analysed for nutritional and antioxidants composition in perspective of its utilisation. Proximate composition, fatty acids profile, carotenoids, such as lycopene and beta-carotene, polyphenols contents, demonstrated the good potential of these residual products as a source of natural compounds, useful for food and nutraceuticals applications. PMID- 27686857 TI - Ganetespib, an HSP90 inhibitor, kills Epstein-Barr virus (EBV)-infected B and T cells and reduces the percentage of EBV-infected cells in the blood. AB - HSP90 inhibitors have been shown to kill Epstein-Barr virus (EBV)-infected cells by reducing the level of EBV EBNA-1 and/or LMP1. We treated virus-infected cells with ganetespib, an HSP90 inhibitor currently being evaluated in multiple clinical trials for cancer and found that the drug killed EBV-positive B and T cells and reduced the level of both EBV EBNA-1 and LMP1. Treatment of cells with ganetespib also reduced the level of pAkt. Ganetespib delayed the onset of EBV positive lymphomas and prolonged survival in SCID mice inoculated with one EBV transformed B-cell line, but not another B-cell line. The former cell line showed lower levels of EBNA-1 after treatment with ganetespib in vitro. Treatment of a patient with T-cell chronic active EBV with ganetespib reduced the percentage of EBV-positive cells in the peripheral blood. These data indicate that HSP90 inhibitors may have a role in the therapy of certain EBV-associated diseases. PMID- 27686858 TI - Oral hygiene practices and their socio-demographic correlates among Nepalese adult: evidence from non communicable diseases risk factors STEPS survey Nepal 2013. AB - BACKGROUND: Oral diseases remain a significant public health problem in Nepal, as do oral health behaviours. Socio-demographic factors play a crucial role in driving oral hygiene practices. This study aims to identify oral hygiene practices and associated socio-demographic factors in Nepalese population. METHODS: This descriptive, cross-sectional study recruited 4200 adults (15-69 years) through multistage cluster sampling. Data obtained from the WHO NCD STEPS instrument version 2.2 were analysed in STATA 13.0 using complex sample weighted analysis. RESULTS: Prevalence of cleaning teeth at least once a day was 94.9 % (95 % CI: 93.7-95.9), while that of cleaning teeth at least twice a day was 9.9 % (95 % CI: 8.2-11.9). Use of fluoridated toothpaste was seen among 71.4 % (95 % CI: 67.9-74.7) respondents. A 3.9 % (95 % CI: 3.1-5.0) made a dental visit in the last 6 months. The 45-69 years age group had lesser odds of cleaning teeth at least once a day (AOR: 0.4; 95 % CI: 0.2-0.8), in comparison to 15-29 years age group. Women had greater odds of cleaning teeth at least twice a day (AOR: 1.7; 95 % CI: 1.1-2.4) and having visited a dentist in the last 6 months (AOR: 2.2; 95 % CI: 1.2-3.8) compared to men. With reference to rural residents, urban population had higher odds of using fluoridated toothpaste (AOR: 2.3; 95 % CI: 1.4-3.4) and making a dental visit within the last 6 months (AOR: 1.9; 95 % CI:1.1-3.6). Inhabitants of the Terai had five-fold (AOR: 4.9; 95 % CI: 3.1-7.8) greater odds of cleaning teeth once per day than did hill residents. Those with higher education had greater odds than non-formal education holders of cleaning teeth at least once a day (AOR: 9.0; 95 % CI: 2.9-27.7), cleaning teeth at least twice a day (AOR: 5.6; 95 % CI: 2.9-10.6), using fluoridated toothpaste (AOR: 13.9; 95 % CI: 8.4-23.1), and having visited a dentist in the last 6 months (AOR: 2.8; 95 % CI: 1.4-5.4). CONCLUSIONS: Cleaning teeth at least once a day is widely prevalent in Nepal and a substantial number of population use fluoridated toothpaste. However, cleaning teeth twice a day and visiting a dentist is less common. Being women, Terai residents, urban residents, and educated were significantly associated with oral hygiene practices assessed in this study. PMID- 27686855 TI - Synthetic lethality in lung cancer and translation to clinical therapies. AB - Lung cancer is a heterogeneous disease consisting of multiple histological subtypes each driven by unique genetic alterations. Despite the development of targeted therapies that inhibit the oncogenic mutations driving a subset of lung cancer cases, there is a paucity of effective treatments for the majority of lung cancer patients and new strategies are urgently needed. In recent years, the concept of synthetic lethality has been established as an effective approach for discovering novel cancer-specific targets as well as a method to improve the efficacy of existing drugs which provide partial but insufficient benefits for patients. In this review, we discuss the concept of synthetic lethality, the various types of synthetic lethal interactions in the context of oncology and the approaches used to identify these interactions, including recent advances that have transformed the ability to discover novel synthetic lethal combinations on a global scale. Lastly, we describe the specific synthetic lethal interactions identified in lung cancer to date and explore the pharmacological challenges and considerations in translating these discoveries to the clinic. PMID- 27686859 TI - Relative efficacy of topical non-steroidal anti-inflammatory drugs and topical capsaicin in osteoarthritis: protocol for an individual patient data meta analysis. AB - BACKGROUND: Pain is the most troubling issue to patients with osteoarthritis (OA), yet current pharmacological treatments offer only small-to-moderate pain reduction. Current guidelines therefore emphasise the need to identify predictors of treatment response. In line with these recommendations, an individual patient data (IPD) meta-analysis will be conducted. The study aims to investigate the relative treatment effects of topical non-steroidal anti-inflammatory drugs (NSAIDs) and topical capsaicin in OA and to identify patient-level predictors of treatment response. METHODS: IPD will be collected from randomised controlled trials (RCTs) of topical NSAIDs and capsaicin in OA. Multilevel regression modelling will be conducted to determine predictors for the specific and the overall treatment effect. DISCUSSION: Through the identification of treatment responders, this IPD meta-analysis may improve the current understanding of the pain mechanisms in OA and guide clinical decision-making. Identifying and prescribing the treatment most likely to be beneficial for an individual with OA will improve the efficiency of patient management. SYSTEMATIC REVIEW REGISTRATION: CRD42016035254. PMID- 27686860 TI - The eIF2A knockout mouse. AB - Eukaryotic initiation factor 2A (eIF2A) is a 65-kDa protein that was first identified in the early 1970s as a factor capable of stimulating initiator methionyl-tRNAi (Met-tRNAMeti) binding to 40S ribosomal subunits in vitro. However, in contrast to the eIF2, which stimulates Met-tRNAMeti binding to 40S ribosomal subunits in a GTP-dependent manner, eIF2A didn't reveal any GTP dependence, but instead was found to direct binding of the Met-tRNAMeti to 40S ribosomal subunits in a codon-dependent manner. eIF2A appears to be highly conserved across eukaryotic species, suggesting conservation of function in evolution. The yeast Saccharomyces cerevisae eIF2A null mutant revealed no apparent phenotype, however, it was found that in yeast eIF2A functions as a suppressor of internal ribosome entry site (IRES)-mediated translation. It was thus suggested that eIF2A my act by impinging on the expression of specific mRNAs. Subsequent studies in mammalian cell systems implicated eIF2A in non canonical (non-AUG-dependent) translation initiation events involving near cognate UUG and CUG codons. Yet, the role of eIF2A in cellular functions remains largely enigmatic. As a first step toward characterization of the eIF2A function in mammalian systems in vivo, we have obtained homozygous eIF2A-total knockout (KO) mice, in which a gene trap cassette was inserted between eIF2A exons 1 and 2 disrupting expression of all exons downstream of the insertion. The KO mice strain is viable and to date displays no apparent phenotype. We believe that the eIF2A KO mice strain will serve as a valuable tool for researchers studying non canonical initiation of translation in vivo. PMID- 27686861 TI - A pre-metazoan origin of the CRK gene family and co-opted signaling network. AB - CRK and CRKL adapter proteins play essential roles in development and cancer through their SRC homology 2 and 3 (SH2 and SH3) domains. To gain insight into the origin of their shared functions, we have investigated their evolutionary history. We propose a term, crk/crkl ancestral (crka), for orthologs in invertebrates before the divergence of CRK and CRKL in the vertebrate ancestor. We have isolated two orthologs expressed in the choanoflagellate Monosiga brevicollis, a unicellular relative to the metazoans. Consistent with its highly conserved three-dimensional structure, the SH2 domain of M. brevicollis crka1 can bind to the mammalian CRK/CRKL SH2 binding consensus phospho-YxxP, and to the SRC substrate/focal adhesion protein BCAR1 (p130CAS) in the presence of activated SRC. These results demonstrate an ancient origin of the CRK/CRKL SH2-target recognition specificity. Although BCAR1 orthologs exist only in metazoans as identified by an N-terminal SH3 domain, YxxP motifs, and a C-terminal FAT-like domain, some pre-metazoan transmembrane proteins include several YxxP repeats in their cytosolic region, suggesting that they are remotely related to the BCAR1 substrate domain. Since the tyrosine kinase SRC also has a pre-metazoan origin, co-option of BCAR1-related sequences may have rewired the crka-dependent network to mediate adhesion signals in the metazoan ancestor. PMID- 27686862 TI - Neural Stem Cell Tumorigenicity and Biodistribution Assessment for Phase I Clinical Trial in Parkinson's Disease. AB - Human pluripotent stem cells (PSC) have the potential to revolutionize regenerative medicine. However undifferentiated PSC can form tumors and strict quality control measures and safety studies must be conducted before clinical translation. Here we describe preclinical tumorigenicity and biodistribution safety studies that were required by the US Food and Drug Administration (FDA) and Australian Therapeutic Goods Administration (TGA) prior to conducting a Phase I clinical trial evaluating the safety and tolerability of human parthenogenetic stem cell derived neural stem cells ISC-hpNSC for treating Parkinson's disease (ClinicalTrials.gov Identifier NCT02452723). To mitigate the risk of having residual PSC in the final ISC-hpNSC population, we conducted sensitive in vitro assays using flow cytometry and qRT-PCR analyses and in vivo assays to determine acute toxicity, tumorigenicity and biodistribution. The results from these safety studies show the lack of residual undifferentiated PSC, negligible tumorigenic potential by ISC-hpNSC and provide additional assurance to their clinical application. PMID- 27686863 TI - Feralisation targets different genomic loci to domestication in the chicken. AB - Feralisation occurs when a domestic population recolonizes the wild, escaping its previous restricted environment, and has been considered as the reverse of domestication. We have previously shown that Kauai Island's feral chickens are a highly variable and admixed population. Here we map selective sweeps in feral Kauai chickens using whole-genome sequencing. The detected sweeps were mostly unique to feralisation and distinct to those selected for during domestication. To ascribe potential phenotypic functions to these genes we utilize a laboratory controlled equivalent to the Kauai population-an advanced intercross between Red Junglefowl and domestic layer birds that has been used previously for both QTL and expression QTL studies. Certain sweep genes exhibit significant correlations with comb mass, maternal brooding behaviour and fecundity. Our analyses indicate that adaptations to feral and domestic environments involve different genomic regions and feral chickens show some evidence of adaptation at genes associated with sexual selection and reproduction. PMID- 27686864 TI - The impact of P2Y12 promoter DNA methylation on the recurrence of ischemic events in Chinese patients with ischemic cerebrovascular disease. AB - The primary mechanism of clopidogrel resistance is still unclear. We aimed to investigate whether the methylation status of the P2Y12 promoter has effects on platelet function and clinical ischemic events. Patients with ischemic cerebrovascular disease were enrolled into our study. Venous blood samples were drawn for thrombelastograpy (TEG) and active metabolite assay. Patients were divided into a case- or control-group based on the occurrence of ischemic events during a one year follow-up. Two TEG parameters between the case and control groups were statistically significant [ADP inhibition rate (ADP%): P = 0.018; ADP induced platelet-fibrin clot strength (MAADP): P = 0.030]. The concentrations of clopidogrel active metabolite had no significant difference (P = 0.281). Sixteen CpG dinucleotides on P2Y12 promoter were tested. Three CpG sites (CpG11 and CpG12 + 13) showed lower methylation status, which correlated with a strong association with increased risk of clinical events. Changes of MAADP and ADP% were also associated with methylation levels of CpG 11 and CpG 12 + 13. Hypomethylation of the P2Y12 promoter is associated with a higher platelet reactivity and increased risk of ischemic events in our patients. Methylation analysis of peripheral blood samples might be a novel molecular marker to help early identification of patients at high risk for clinical ischemic events. PMID- 27686865 TI - The Architecture of the Cytoplasmic Region of Type III Secretion Systems. AB - Type III secretion systems (T3SSs) are essential devices in the virulence of many Gram-negative bacterial pathogens. They mediate injection of protein effectors of virulence from bacteria into eukaryotic host cells to manipulate them during infection. T3SSs involved in virulence (vT3SSs) are evolutionarily related to bacterial flagellar protein export apparatuses (fT3SSs), which are essential for flagellar assembly and cell motility. The structure of the external and transmembrane parts of both fT3SS and vT3SS is increasingly well-defined. However, the arrangement of their cytoplasmic and inner membrane export apparatuses is much less clear. Here we compare the architecture of the cytoplasmic regions of the vT3SSs of Shigella flexneri and the vT3SS and fT3SS of Salmonella enterica serovar Typhimurium at ~5 and ~4 nm resolution using electron cryotomography and subtomogram averaging. We show that the cytoplasmic regions of vT3SSs display conserved six-fold symmetric features including pods, linkers and an ATPase complex, while fT3SSs probably only display six-fold symmetry in their ATPase region. We also identify other morphological differences between vT3SSs and fT3SSs, such as relative disposition of their inner membrane-attached export platform, C-ring/pods and ATPase complex. Finally, using classification, we find that both types of apparatuses can loose elements of their cytoplasmic region, which may therefore be dynamic. PMID- 27686866 TI - Ocular adnexal marginal zone lymphoma arising in a patient with IgG4-related ophthalmic disease. AB - A 41-year-old man was diagnosed with immunoglobulin G4-related disease (IgG4-RD) in both eyelids 4 years ago and exhibited good response to steroid therapy. However, rapid swelling of the right eyelid lesion was recently observed. As IgG4 RD progression was suspected, biopsy was performed. Although the histology was consistent with IgG4-RD, the infiltrating large atypical lymphoid cells showed immunoglobulin light-chain restriction and IgH gene rearrangement. Consequently, he was diagnosed with extranodal marginal zone lymphoma with abundant IgG4 positive cells. PMID- 27686867 TI - Copy-number analysis identified new prognostic marker in acute myeloid leukemia. AB - Recent advances in genomic technologies have revolutionized acute myeloid leukemia (AML) understanding by identifying potential novel actionable genomic alterations. Consequently, current risk stratification at diagnosis not only relies on cytogenetics, but also on the inclusion of several of these abnormalities. Despite this progress, AML remains a heterogeneous and complex malignancy with variable response to current therapy. Although copy-number alterations (CNAs) are accepted prognostic markers in cancers, large-scale genomic studies aiming at identifying specific prognostic CNA-based markers in AML are still lacking. Using 367 AML, we identified four recurrent CNA on chromosomes 11 and 21 that predicted outcome even after adjusting for standard prognostic risk factors and potentially delineated two new subclasses of AML with poor prognosis. ERG amplification, the most frequent CNA, was related to cytarabine resistance, a cornerstone drug of AML therapy. These findings were further validated in The Cancer Genome Atlas data. Our results demonstrate that specific CNA are of independent prognostic relevance, and provide new molecular information into the genomic basis of AML and cytarabine response. Finally, these CNA identified two potential novel risk groups of AML, which when confirmed prospectively, may improve the clinical risk stratification and potentially the AML outcome. PMID- 27686869 TI - Hydrogenation-controlled phase transition on two-dimensional transition metal dichalcogenides and their unique physical and catalytic properties. AB - Two-dimensional (2D) transition metal dichalcogenides (TMDs) have been widely used from nanodevices to energy harvesting/storage because of their tunable physical and chemical properties. In this work, we systematically investigate the effects of hydrogenation on the structural, electronic, magnetic, and catalytic properties of 33 TMDs based on first-principles calculations. We find that the stable phases of TMD monolayers can transit from 1T to 2H phase or vice versa upon the hydrogenation. We show that the hydrogenation can switch their magnetic and electronic states accompanying with the phase transition. The hydrogenation can tune the magnetic states of TMDs among non-, ferro, para-, and antiferro magnetism and their electronic states among semiconductor, metal, and half-metal. We further show that, out of 33 TMD monolayers, 2H-TiS2 has impressive catalytic ability comparable to Pt in hydrogen evolution reaction in a wide range of hydrogen coverages. Our findings would shed the light on the multi-functional applications of TMDs. PMID- 27686870 TI - A new C20-diterpenoid alkaloid from the lateral roots of Aconitum carmichaeli. AB - A new C20-diterpenoid alkaloid carmichaedine (1) and six known alkaloids (2-7) were isolated from the lateral roots of Aconitum carmichaeli. Their structures were established on the basis of extensive spectroscopic analyses. Compound 1 exhibited potent antibacterial activity against Bacillus subtilis with minimum inhibitory concentration of 8 MUg/mL. PMID- 27686868 TI - Pan-Raf co-operates with PI3K-dependent signalling and critically contributes to myeloma cell survival independently of mutated RAS. AB - Direct therapeutic targeting of oncogenic RAS is currently still impossible due to lack of suitable pharmacological inhibitors. Because specific blockade of druggable RAS effectors might represent an alternative treatment approach, we evaluated the role of the Raf complex for multiple myeloma (MM) pathobiology. We found frequent overexpression of the Raf isoforms (A-, B- and C-Raf) and downstream activation of MEK1,2/ERK1,2 in MM cells. Concomitant inhibition of all Raf isoforms (pan-Raf inhibition) by RNAi or pharmacological inhibitors was required to strongly induce apoptosis in human MM cell lines (HMCLs), in primary MM cells in vitro, and in a syngeneic MM mouse model in vivo. The anti-MM effect of pan-Raf inhibition did not correlate with the RAS mutation status, and functionally appeared to involve both MEK-dependent and -independent mechanisms. Furthermore, transcriptome analyses revealed that pan-Raf activity affects PI3K dependent signalling, thus highlighting a functional link between the RAS/Raf and PI3K/mTOR/Akt pro-survival pathways. Accordingly, pharmacological inhibition of PI3K strongly enhanced the anti-MM effect of pan-Raf inhibition in MM cell lines and in primary MM cells in vitro and in vivo. Concomitant pan-Raf/PI3K inhibition was also effective in carfilzomib- and lenalidomide-resistant MM models underscoring that this attractive therapeutic anti-MM strategy is suitable for immediate clinical translation. PMID- 27686871 TI - Role of the Internet in Care Initiation by People Living With HIV. AB - People frequently use the internet to obtain information, including information about health, but we lack understanding of how people living with HIV (PLHIV) use the internet in their care and treatment decisions. In this secondary analysis, interviews with 23 individuals who initiated HIV care at an urban, Midwestern medical center and mentioned internet use were analyzed using qualitative content analysis to explore how they used the internet during the process of initiating HIV care. HIV care had been initiated by this sample from less than one month to three years post-diagnosis. Participants discussed the internet as a source of information about their diagnosis that influenced their care and treatment decisions. Five themes were predominant: (i) The internet alerted me to the possibility of HIV, (ii) the internet showed me a solution is available, (iii) the internet influenced my decisions about care, (iv) the internet empowered me to participate in my treatment decisions, and (v) the internet gave me hope for my future. The results suggest that the internet has the potential to provide information that can profoundly influence PLHIVs' acceptance of care and treatment decisions. Clinicians face a new reality in which patients use internet resources to obtain information and shape opinions about HIV treatment and care initiation decision-making. Guiding PLHIV in their selection of online resources is one approach to educating and empowering individuals as they cope with their diagnosis and contemplate decisions regarding HIV care and treatment.

PMID- 27686873 TI - Protocatechuic Acid: Inhibition of Fibril Formation, Destabilization of Preformed Fibrils of Amyloid-beta and alpha-Synuclein, and Neuroprotection. AB - Protocatechuic acid (PCA) is the major metabolite of the anthocyanin known as cyanidin 3-glucoside. It is found in plasma and tissues, such as the brain, heart, liver, and kidneys, following consumption of a rich source of this flavonoid. The abnormal pathological assembly of amyloid-beta (Abeta) and alpha synuclein (alphaS) is an underlying mechanism involved in the formation of amyloid plaques and Lewy bodies in the brain, which are responsible for neuropathology symptoms in Alzheimer's (AD) and Parkinson's diseases (PD), respectively. This research was performed to evaluate the protective effects of PCA, by establishing its potential role in inhibiting aggregation and fibril destabilization of Abeta and alphaS proteins. It has been found that PCA inhibits the aggregation of Abeta and alphaS and destabilizes their preformed fibrils. These results were confirmed by TEM images, electrophoresis, and immunoblotting experiments. Furthermore, PCA prevents the death of PC12 cells triggered by Abeta and alphaS-induced toxicity. PMID- 27686872 TI - Delayed Implants Outcome in Maxillary Molar Region. AB - BACKGROUND: The aim of the present study was to assess bone volume changes in maxillary molar regions after delayed implants placement. MATERIALS AND METHODS: Patients presented large bone defects after tooth extractions. Reactive soft tissue was left into the defects. No grafts were used. Cone beam computed tomography (CBCT) scans were performed before tooth extractions, at implant placement (at 3 months from extraction) and 3 years after implant placement, bone volume measurements were assessed. RESULTS: Bucco-lingual width showed a statistically significant decrease (p = .013) at implant placement, 3 months after extraction. Moreover, a statistically significant increase (p < .01) was measured 3 years after implant placement. No statistically significant differences (p > .05) were found between baseline values (before extraction) and at 3 years from implant placement. Vertical dimension showed no statistically significant differences (p > .05) at implant placement, 3 months after extraction. Statistically significant differences (p < .0001) were found between baseline values (before extraction) and at 3 months from implant placement as well as between implant placement values and 3 years later. CONCLUSION: CT scans presented successful outcome of delayed implants placed in large bone defects at 3-year follow-up. PMID- 27686874 TI - Screening patients for communication difficulty: The diagnostic accuracy of the IFCI staff questionnaire. AB - PURPOSE: Many patients have difficulty communicating about their healthcare. At present there is no tool to identify these patients. This research investigated whether the Inpatient Functional Communication Interview Staff Questionnaire (IFCI SQ) could detect patients who have difficulty communicating their healthcare needs by investigating the sensitivity, specificity and internal consistency of the IFCI SQ. METHOD: Fifty patients and their nurses participated in this research. Every second consecutive admission on the general medical ward of a hospital was assessed for communication difficulty by a speech-language pathologist on the IFCI and screened for communication difficulty by a nurse using the IFCI SQ. RESULT: At a cut off score of <2, the IFCI SQ had a sensitivity of 95% and a specificity of 77% compared with the IFCI. The IFCI SQ is a useful test in identifying patients who have communication difficulty and is an extremely good test at ruling out patients who do not have communication difficulty. The internal consistency of the IFCI SQ was also high at 0.954. CONCLUSION: The IFCI SQ is a promising tool to detect patients in hospital with communication difficulty. Further research is required to explore the psychometric properties of the IFCI SQ in more detail. PMID- 27686875 TI - UNderstanding uptake of Immunisations in TravellIng aNd Gypsy communities (UNITING): a qualitative interview study. AB - BACKGROUND: Gypsies, Travellers and Roma (referred to as Travellers) are less likely to access health services, including immunisation. To improve immunisation rates, we need to understand what helps and hinders individuals in these communities in taking up immunisations. AIMS: (1) Investigate the barriers to and facilitators of acceptability and uptake of immunisations among six Traveller communities across four UK cities; and (2) identify possible interventions to increase uptake of immunisations in these Traveller communities that could be tested in a subsequent feasibility study. METHODS: Three-phase qualitative study underpinned by the social ecological model. Phase 1: interviews with 174 Travellers from six communities: Romanian Roma (Bristol); English Gypsy/Irish Traveller (Bristol); English Gypsy (York); Romanian/Slovakian Roma (Glasgow); Scottish Showpeople (Glasgow); and Irish Traveller (London). Focus on childhood and adult vaccines. Phase 2: interviews with 39 service providers. Data were analysed using the framework approach. Interventions were identified using a modified intervention mapping approach. Phase 3: 51 Travellers and 25 service providers attended workshops and produced a prioritised list of potentially acceptable and feasible interventions. RESULTS: There were many common accounts of barriers and facilitators across communities, particularly across the English speaking communities. Scottish Showpeople were the most similar to the general population. Roma communities experienced additional barriers of language and being in a new country. Men, women and service providers described similar barriers and facilitators. There was widespread acceptance of childhood and adult immunisation, with current parents perceived as more positive than their elders. A minority of English-speaking Travellers worried about multiple/combined childhood vaccines, adult flu and whooping cough. Cultural concerns about vaccines offered during pregnancy and about human papillomavirus were most evident in the Bristol English Gypsy/Irish Traveller community. Language, literacy, discrimination, poor school attendance, poverty and housing were identified by Travellers and service providers as barriers for some. Trustful relationships with health professionals were important and continuity of care was valued. A few English-speaking Travellers described problems of booking and attending for immunisation. Service providers tailored their approach to Travellers, particularly the Roma. Funding cuts, NHS reforms and poor monitoring challenged their work. Five 'top-priority' interventions were agreed across communities and service providers to improve the immunisation among Travellers who are housed or settled on an authorised site: (1) cultural competence training for health professionals and frontline staff; (2) identification of Travellers in health records to tailor support and monitor uptake; (3) provision of a named frontline person in general practitioner practices to provide respectful and supportive service; (4) flexible and diverse systems for booking appointments, recall and reminders; and (5) protected funding for health visitors specialising in Traveller health, including immunisation. LIMITATIONS: No Travellers living on the roadside or on unofficial encampments were interviewed. We should exert caution in generalising to these groups. FUTURE WORK: To include development, implementation and evaluation of a national policy plan (and practice guidance plan) to promote the uptake of immunisation among Traveller communities.

AB - The study aimed to investigate the experience of adults with a diagnosis of psychosis and who have survived childhood physical abuse. We interviewed eight participants and used interpretative phenomenological analysis to generate themes. The main themes were of perceiving an everyday world of aggression and contempt by others, pervasive mistrust, feeling isolated and for some, attacking oneself with hate. Most participants were also able to reflect on what they saw as 'paranoia' or 'voices'. Paranoia was described as a fluctuating compulsive 'thread' of meaning, feeling and sometimes a transformation of the self. The paranoia and voices experienced often involved a dread of murderous obliteration. The discussion considers the relevance of altered consciousness, psychotic states of self and the contribution of mutating narrative and meaning. Our findings point to the importance of therapy for interpersonal difficulties and the long term effects of trauma. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - The histopathologic characteristics of reactions caused by the many novel anticancer agents are under-recognized. We report a case of a 67-year-old female with locally advanced metastatic breast cancer, who initially presented with an extensive reticulated erythematous patch on the trunk caused by intravascular metastases confirmed by a skin biopsy. Owing to disease progression, she was started on ixabepilone, a mitotic inhibitor. While receiving ixabepilone, another skin biopsy was obtained and initially interpreted as extramammary Paget's disease. However, the biopsy showed metaphase arrest of numerous keratinocytes in the basilar and suprabasilar epidermis. Atypical epithelial cells were only present in the intravascular spaces similar to the initial biopsy. Given the temporal association between the initiation of ixabepilone therapy and the epidermal mitotic arrest, a diagnosis of chemotherapy reaction to ixabepilone was rendered. Ixabepilone is an analog of epothilone, a microtubule stabilizer causing mitotic arrest of the cell cycle approved for the treatment of metastatic and locally advanced treatment-resistant breast cancer. The demonstration of epidermal mitotic arrest caused by ixabepilone is without precedent. The case emphasizes the importance of considering a chemotherapy reaction in the histologic differential diagnosis of epidermal mitotic arrest in a cancer patient receiving chemotherapy.

AB - BACKGROUND: Conducting federally mandated community health needs assessments through academic-practice partnerships provides new opportunities for developing population health nursing competencies. OBJECTIVES: The purpose of this article was to describe how a baccalaureate practicum experience within such an assessment process, involving health care system partners, re-affirms the importance of community and population health assessment in the development of future nursing leaders. RESULTS: Student evaluations indicated an emerging appreciation for the social determinants of health, the power of partnerships, and the importance of diversity. Integrating health care and public health system perspectives on assessment meets both public health and nursing accreditation standards and extends student leadership experiences. Such integration also improves regional capacity for improving population health. CONCLUSIONS: Federal mandates for community health needs assessments provide opportunities to advance leadership roles for nursing graduates throughout the health care system, and for confirming the importance of community assessment as an essential nursing competency. PMID- 27686879 TI - Evaluation of conservative approach in the management of ureteroenteric strictures following radical cystectomy with Bricker ileal conduit: a single center experience. AB - OBJECTIVE: The aim of this study was to evaluate the risk factors and treatment options for ureteroenteric strictures (UES) following radical cystectomy (RC) and ileal conduit (IC) formation, and specifically to comment on the conservative management of UES in asymptomatic patients. MATERIALS AND METHODS: The datasheets were reviewed of 304 consecutive patients who were treated with an RC and IC between January 2001 and May 2011 in a Belgian tertiary center and who followed a strict follow-up protocol. Long-term treatment outcomes were retrospectively analyzed. RESULTS: Twenty-two patients (7.2%) were diagnosed with UES (affecting 27 ureters in total), when a new-onset hydroureteronephrosis or increase of the pre-existing hydroureteronephrosis was detected by ultrasound or computed tomography. A retrograde loopogram was then performed to confirm the UES. The mean follow-up time was 33 months. A decline in renal function, the presence of flank pain and urinary tract infections were indications for interventional treatment. Six patients underwent double-J stent placement, two patients received percutaneous nephrostomies as a definitive treatment and two patients underwent ureterointestinal reimplantation. Asymptomatic patients with a UES and a favorable renal function were conservatively managed. They remained asymptomatic during follow-up and required no active treatment. CONCLUSIONS: No clinical variable was independently associated with an increased risk of UES. These long term data suggest that a selected patient population of asymptomatic patients with good renal function at the time of UES diagnosis can be safely managed conservatively. PMID- 27686880 TI - Combination of preoperative NLR, PLR and CEA could increase the diagnostic efficacy for I-III stage CRC. AB - BACKGROUND: Inflammation plays an important role in the development and progression of CRC. The members of inflammatory biomarkers, preoperative NLR and PLR, have been proved by numerous studies to be promising prognostic biomarkers for CRC. However, the diagnostic value of the two biomarkers in CRC remains unknown, and no study reported the combined diagnostic efficacy of NLR, PLR and CEA. METHODS: Five hundred and fifty-nine patients with I-III stage CRC undergoing surgical resection and 559 gender- and age-matched healthy controls were enrolled in this retrospective study. NLR and PLR were calculated from preoperative peripheral blood cell count detected using white blood cell five classification by Sysmex XT-1800i Automated Hematology System and serum CEA were measured by electrochemiluminescence by ELECSYS 2010. The diagnostic performance of NLR, PLR and CEA for CRC was evaluated by ROC curve. RESULTS: Levels of NLR and PLR in the cases were significantly higher than them in the healthy controls. ROC curves comparison analyses showed that the diagnostic efficacy of NLR (AUC=.755, 95%CI=.728-.780) alone for CRC was significantly higher than PLR (AUC=.723, 95%CI=.696-.749, P=.037) and CEA (AUC=.690, 95%CI=.662-.717, P=.002) alone. In addition, the diagnostic efficacy of the combination of NLR, PLR and CEA(AUC=.831, 95%CI=.807-.852)for CRC was not only significantly higher than NLR alone but also higher than any combinations of the two of these three biomarkers (P<.05). Moreover, the NLR and PLR in the patients with TNM stage I/II was higher than that in the healthy controls, and patients with stage III had a higher NLR and PLR than those with stage I/II, but no significant difference was observed. CONCLUSION: Our study indicated that preoperative NLR could be a CRC diagnostic biomarker, even for early stage CRC, and the combination of NLR, PLR and CEA could significantly improve the diagnostic efficacy. PMID- 27686881 TI - The effects of anxiety and depression on in vitro fertilisation outcomes of infertile Chinese women. AB - The object was to assess anxiety and depression during in vitro fertilisation (IVF) treatment and determine IVF-related psychological factors in infertile Chinese women. The self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate anxiety and depression among 842 patients, respectively. A univariate analysis was used to compare variables among three SAS groups and three SDS groups. Anxiety and depression were both represented in 21.3% of the cases. Patients <35 years tended to be more anxious. In women <35 years, the SDS scores were higher with lower educational backgrounds and female or couple's infertility, while the SAS scores were higher in female or couple's infertility. In older ones, the SDS scores were higher in those with lower educational backgrounds and longer time for infertility, while the SAS scores were higher in those with lower educational backgrounds. In SAS groups 1-3, the embryo availability was 5.0 (3.0-8.0), 5.0 (3.0-8.0), and 3.0 (2.0-4.5) (p = .013); and the fertilisation rate was 91.9, 90.4, and 81.8% (p < .001), respectively. We concluded that infertile women experience anxiety and depression during IVF treatment, especially in women <35 years. Younger women with female infertility would be more anxious and depressive while higher education can protect them from depression. In older ones, they would experience more depressive with longer time for infertility and be less anxious and depressive with higher education. Anxiety affects the fertilisation rate and embryo availability. PMID- 27686882 TI - Determination of an optimally sensitive and specific chemical exchange saturation transfer MRI quantification metric in relevant biological phantoms. AB - The purpose of this study was to develop realistic phantom models of the intracellular environment of metastatic breast tumour and naive brain, and using these models determine an analysis metric for quantification of CEST MRI data that is sensitive to only labile proton exchange rate and concentration. The ability of the optimal metric to quantify pH differences in the phantoms was also evaluated. Novel phantom models were produced, by adding perchloric acid extracts of either metastatic mouse breast carcinoma cells or healthy mouse brain to bovine serum albumin. The phantom model was validated using 1 H NMR spectroscopy, then utilized to determine the sensitivity of CEST MRI to changes in pH, labile proton concentration, T1 time and T2 time; six different CEST MRI analysis metrics (MTRasym , APT*, MTRRex , AREX and CESTR* with and without T1 /T2 compensation) were compared. The new phantom models were highly representative of the in vivo intracellular environment of both tumour and brain tissue. Of the analysis methods compared, CESTR* with T1 and T2 time compensation was optimally specific to changes in the CEST effect (i.e. minimal contamination from T1 or T2 variation). In phantoms with identical protein concentrations, pH differences between phantoms could be quantified with a mean accuracy of 0.6 pH units. We propose that CESTR* with T1 and T2 time compensation is the optimal analysis method for these phantoms. Analysis of CEST MRI data with T1 /T2 time compensated CESTR* is reproducible between phantoms, and its application in vivo may resolve the intracellular alkalosis associated with breast cancer brain metastases without the need for exogenous contrast agents. PMID- 27686883 TI - Patterns of sexual behaviour and sexual healthcare needs among transgender individuals in Melbourne, Australia, 2011-2014. AB - OBJECTIVE: Literature surrounding the healthcare needs of transgender individuals is limited in Australia. This study aimed to investigate the demographic characteristics, risk behaviours and HIV/STI positivity among male-to-female (MTF) and female-to-male (FTM) transgender individuals attending Melbourne Sexual Health Centre (MSHC), Australia, between 2011 and 2014. METHOD: A retrospective cohort analysis for 133 transgender individuals was conducted based on the first visit of individuals to MSHC during the study period. Demographic characteristics, sexual behaviours and HIV/STI positivity were examined. RESULTS: The majority of transgender individuals were single or never married (74%; n=99). Almost half of the individuals (47%; n=62) had ever engaged in sex work during their lifetime. The median number of male sexual partners (MSP) reported in the last 3 months was 1 (IQR: 1-2) and with female sexual partners (FSP) was 2 (IQR: 1-4). For those who reported having sexual partners in the previous 3 months, always using condoms with MSP was 31% (n=22), and that with FSP was 18% (n=2). HIV/STI positivity during the study period was 7% (n=8) for chlamydia, 5% (n=6) for gonorrhoea, 5% (n=5) for syphilis and 1% (n=1) for HIV. Hormone use for reassignment was reported by 63% (n=90) of individuals and reassignment surgery was reported by 27% (n=29+6=35). CONCLUSIONS: Transgender individuals in this study were found to be a diverse group, with a history of sex work being a common feature. These findings indicate that transgender individuals' sexual healthcare needs differ substantially from those in other countries, including the US and Canada. Attention to differences in MTF and FTM transgender persons must be considered in healthcare settings in Australia.

PMID- 27686884 TI - Trichomonas vaginalis infection is uncommon in the British general population: implications for clinical testing and public health screening. AB - INTRODUCTION: Variable use of new molecular assays, asymptomatic infections and a lack of population data mean that the population burden of Trichomonas vaginalis is uncertain. We investigated the age-specific prevalence of T. vaginalis within the sexually active British general population to inform testing strategies. METHODS: Britain's third National Survey of Sexual Attitudes and Lifestyle (Natsal-3) is a probability sample survey of 15 162 individuals aged 16-74 years, undertaken during 2010-2012. Urine from 4386 participants aged 16-44 years reporting >=1 lifetime sexual partner was tested for T. vaginalis using in-house real-time PCR. RESULTS: Urinary T. vaginalis was detected in seven women and no men providing urine samples, giving a weighted prevalence estimate of 0.3% (95% CI 0.1% to 0.5%) in sexually experienced women aged 16-44 years. Of the seven women with T. vaginalis detected, four were of black or mixed ethnicity (prevalence 2.7% (0.9% to 7.7%) in this group) and five reported recent partners of black or mixed ethnicity. Six of the women reported symptoms, and five reported sexual health clinic attendance in the past 5 years (prevalence in those reporting clinic attendance: 1.0% (0.4% to 2.3%)). The prevalence of a self reported history of T. vaginalis (past 5 years) was 0.1% (0.0% to 0.2%) in women and 0.0% (0.0% to 0.2%) in men aged 16-44 years. CONCLUSIONS: Our British population prevalence estimates indicate that T. vaginalis is a rare infection. These data support policies that restrict asymptomatic screening for T. vaginalis and suggest deployment of molecular tests should be focused within clinical settings and guided by symptoms and local demography. PMID- 27686886 TI - Neuroprotective Effects of Cannabidiol in Hypoxic Ischemic Insult. The Therapeutic Window in Newborn Mice. AB - BACKGROUND: A relevant therapeutic time window (TTW) is an important criterion for considering the clinical relevance of a substance preventing newborn hypoxic ischemic (HI) brain damage. OBJECTIVE: To test the TTW of the neuroprotective effects of cannabidol (CBD), a non-psychoactive cannabinoid in a model of newborn HI brain damage. METHOD: 9-10 day-old C57BL6 mice underwent a HI insult (10% oxygen for 90 min after left carotid artery electrocoagulation). Then, CBD 1 mg/kg or vehicle were administered s.c. 15 min, or 1, 3, 6, 12, 18 or 24 h after the end of the HI insult. Seven days later brain damage was assessed using T2W Magnetic Resonance Imaging scan (ipsilateral hemisphere volume loss, IVHL) and histological studies: Nissl staining (neuropathological score), TUNEL staining (apoptotic damage) and immunohistochemistry with glial fibrillary acidic protein (astrocyte viability) or ionized calcium binding adaptor molecule (microglial activation). RESULTS: CBD administered up to 18 h after HI reduced IHVL and neuropathological score by 60%, TUNEL+ count by 90% and astrocyte damage by 50%. In addition, CBD blunted the HI-induced increase in microglial population. When CBD administration was delayed 24 h, however, the neuroprotective effect was lost in terms of IHVL, apoptosis or astrogliosis reduction. CONCLUSION: CBD shows a TTW of 18 h when administered to HI newborn mice, which represents a broader TTW than reported for other neuroprotective treatments including hypothermia. PMID- 27686887 TI - Enhancing Social Responsibility and Prosocial Leadership to Prevent Aggression, Peer Victimization, and Emotional Problems in Elementary School Children. AB - Testing the theories that form the basis of prevention programs can enhance our understanding of behavioral change and inform the development, coordination, and adaptation of prevention programs. However, theories of change showing the linkages from intervention program components to risk or protective factors to desired outcomes across time are rarely specified or tested. In this 2-year longitudinal study, we test the theory that increases in two protective factors (i.e., children's prosocial leadership and their teachers' expectations of social responsibility) targeted by the WITS Programs (Walk Away, Ignore, Talk it Out, and Seek Help) would be associated with declines in peer victimization, aggression, and emotional problems. Participants included Canadian students, in grades 1-4 at baseline (n = 1329) and their parents and teachers. Consistent with our theory of change, variability in program implementation (adherence and integration) and in children's use of program skills (child responsiveness) are related to increases in both protective factors. Increases in these protective factors are associated with subsequent declines in children's aggression, victimization, and emotional problems. We discuss how enhancement of these protective factors may operate to improve child outcomes and the need for theory based research to refine and improve the effectiveness of intervention strategies and to improve program scale-up. PMID- 27686888 TI - Role of lasers as an adjunct to scaling and root planing in patients with type 2 diabetes mellitus: a systematic review. AB - The aim of the study was to assess the efficacy of adjunctive use of laser therapy (LT) alone or antimicrobial photodynamic therapy (aPDT) to improve clinical periodontal and HbA1c levels in patients with both chronic periodontitis (CP) and type 2 diabetes mellitus (T2DM). Electronic search of the MEDLINE, PubMed, EMBASE, Science Direct, and SCOPUS databases were combined with hand searching of articles published from 1975 up to and including March 2016 using relevant MeSH terms. Six studies were selected for this review. In these six studies, laser treatment was applied, after scaling and root planing (SRP), in two ways: Three studies used laser alone and three studies used laser with photosensitizer. All the six included studies reporting clinical periodontal and glycemic parameters showed that LT and aPDT were effective in the treatment of CP in T2DM subjects at follow-up. Two studies showed significantly better periodontal outcomes for LT as an adjunct to SRP as compared to SRP alone, whereas four studies showed comparable periodontal outcomes among adjunctive LT or aPDT with SRP. Two studies showed significant reduction of HbA1c levels in LT and aPDT as compared to SRP, whereas three studies showed comparable percentage levels at follow-up. It remains debatable whether LT or aPDT as adjunct to SRP is more effective as compared to SRP alone in the improvement of clinical periodontal and glycemic control in patients with both CP and T2DM, given that the scientific evidence is weak. PMID- 27686889 TI - Treatment outcome of vocal cord leukoplakia by transoral laser microsurgery. AB - The aim of this study is to evaluate the treatment outcome and analyze the associated factors of postoperative recurrence in patients who received transoral laser microsurgery for vocal cord leukoplakia. The demographic, histopathological data were retrospectively reviewed and the factors associated with recurrence of vocal leukoplakia after surgery were analyzed statistically. A total of 44 patients, including 36 males and 8 females, with a mean age of 50.4 +/- 13.4 years, were enrolled. All the patients received excision of the vocal leukoplakia by carbon dioxide laser (2-4 Watt, ultrapulse mode) under general anesthesia. No patients had malignant transformation after surgery. Postoperative recurrence occurred in 10 patients (22.7 %). Univariate analysis showed that patients who had the habit of cigarette smoking, alcohol drinking, and presence of gastroesophageal reflux disease tended to recur. Among these risk factors, presence of gastroesophageal reflux disease (odds ratio 8.43) was the independent prognostic factor for recurrence using multivariate logistic regression analysis. Carbon dioxide laser excision is effective for treating vocal leukoplakia that is still confined to dysplasia of any degree, with acceptable morbidity. This study suggests that the presence of gastroesophageal reflux disease is the prognostic indicator for postoperative recurrence of vocal leukoplakia. Aggressive treatment of reflux disease for those who have received surgical excision for vocal leukoplakia is indicated. PMID- 27686891 TI - Senior staff need more support to stay in post.

PMID- 27686890 TI - Treatment of periorbital wrinkles using multipolar fractional radiofrequency in Korean patients. AB - A limited number of studies have evaluated the efficacy and safety of electrode pin fractional radiofrequency (FRF) for periorbital wrinkle treatment in Asian patients, but none have measured noninvasive methodological objective parameters such as periorbital wrinkle area. This study aimed to investigate the efficacy and safety of electrode pin multipolar FRF for the improvement of periorbital wrinkles in Korean patients by using a noninvasive methodological objective parameter. Seventy female subjects with periorbital wrinkles (age range, 40-60 years) participated in this study. Each patient underwent three sessions of FRF treatment to the periorbital region separated by 2-week intervals. The area of periorbital wrinkles was analyzed by using a Robo Skin Analyzer CS50 at 4 weeks after the final treatment session. Periorbital wrinkle area was significantly decreased at 1-month follow-up (75.77 +/- 29.46 mm2) compared to baseline (94.74 +/- 31.62 mm2). The improvement ratio of periorbital wrinkle area was 20.02 %. Side effects were limited to transient mild erythema, swelling, and crusts. Pain was tolerable without local anesthesia. Our findings suggest that the multipolar electrode pin FRF can be an effective and safe method for reducing periorbital wrinkles in Asian patients.

AB - Aim This article describes the development and testing of an Excel-based scheduling solution for the flexible allocation and reallocation of nurses to cover sudden, unplanned absences among permanent nursing staff. Method A quasi experimental, one group, pre- and post-test study design was used ( Box 1 ) with total sampling. Participants (n=17) were selected purposefully by including all ward managers (n=8) and assistant ward managers (n=9) from one university hospital department. The number of sudden absences among the nursing staff was identified during two 4-week data collection periods (pre- and post-test). Results During the use of the paper-based scheduling system, 121 absences were identified; during the use of the Excel-based system, 106 were identified. The main reasons for the use of flexible 'floating' nurses were sick leave (n=66) and workload (n=31). Other reasons (n=29) included patient transfer to another hospital, scheduling errors and the start or end of employment. Conclusion The Excel-based scheduling solution offered better support in obtaining substitute labour inside the organisation, with smaller employment costs. It also reduced the number of tasks ward managers had to carry out during the process of reallocating staff.

AB - The move towards healthcare being delivered predominantly in people's own homes has been seen as creating more choice and giving patients better access to care. How this is being delivered in practice is under question as district nursing teams endeavour to meet a range of needs and coordinate the transfer of care from hospital to home. The research project outlined in this article explored district nurses' views on what are the 'enablers' and 'barriers' to the transfer of care from hospital to home.

AB - BACKGROUND: Biomarkers for the early prediction of the severity of acute pancreatitis (AP) are urgently needed for clinical management of the disease. Angiopoietin-2 (Ang-2), one of the autocrine peptides that reduce endothelial permeability, has been found to be associated with various diseases, including inflammatory disorders. AIMS: This study aimed to determine whether serum Ang-2 could serve as a noninvasive biomarker for the early prediction of persistent organ failure (POF) in acute pancreatitis. METHODS: A total of 120 AP patients were prospectively enrolled at Jinling Hospital. Serum samples were collected on admission. Clinical and laboratory data were recorded. Ang-2 levels were measured by enzyme-linked immunosorbent assay. RESULTS: A total of 37 patients developed POF and were classified as having severe AP (SAP). Ang-2 was significantly higher on admission in patients who developed POF than in those who did not (p < 0.001 for all). Furthermore, receiver operating characteristic (ROC) curve analysis revealed that Ang-2 could distinguish patients who developed POF from mild AP (MAP, area under ROC curve [AUC] = 0.88, 95 % CI 0.78-0.94) and moderately severe AP patients (MSAP, AUC = 0.74, 95 % CI 0.63-0.83). In addition, multivariate logistic regression showed that increased Ang-2 was an independent predictor of developing POF between subgroups with MSAP and SAP (OR 7.2, 95 % CI 2.7-19.4) and among all AP patients (OR 12.1, 95 % CI 4.8-30.3). CONCLUSIONS: Elevated serum Ang-2 levels on admission may be a promising biomarker for the prediction of POF in AP. PMID- 27686936 TI - Skin infection by Mycobacterium marinum.

AB - Gregarines thrive in the digestive tract of arthropods and may be deleterious to their hosts, especially when present in high densities. The impact of parasites on these invertebrates may affect both the ecosystem equilibrium and human economic activities. However, information available on gregarines in Spain is limited. Therefore, a microscopic study on prevalence of gregarine infection in 560 insects and crustaceans was undertaken in Madrid and Tarragona.Gregarina ormierei (78 % prevalence), Stylocephalus gigas (56 %), Oocephalus hispanus (13 %) and Actinocephalus permagnus (only one infected out of six beetles examined) were found in coleopteran hosts. Gregarina ovata and G. chelidurellae showed moderate frequency of infection (35 %) in dermapterans. An undescribed Gregarina sp. (76 % prevalence) was observed for the first time in freshwater decapod crustaceans. Interestingly, G. ormierei showed a noticeable phenotypic dimorphism, which justifies its redescription based on modern taxonomic criteria. Sequences of the 18S rRNA gene could be obtained only in the presence of highly prevalent gregarines. G. ormierei and Gregarina sp. were related (85 and 94 % identity by BLASTN, respectively) to G. basiconstrictonea and G. cloptoni, respectively, whereas S. gigas was closely related to both Xiphocephalus ellisi and S. giganteus (>97 % identity). Phylogenetic trees based on ribosomal sequences unequivocally grouped these new isolates either with the Gregarinidae (G. ormierei and Gregarina sp.) or the Stylocephalidae (S. gigas). PMID- 27686941 TI - Carboxymethyl Starch Excipients for Drug Chronodelivery. AB - Carboxymethyl starch (CMS) is a pH-responsive excipient exhibiting also interesting properties for applications in delayed drug delivery systems. This work was aimed to investigate the release properties of monolithic and dry-coated tablets based on ionic sodium CMS and on protonated CMS, formulated with three model tracers: acetaminophen, acetylsalicylic acid (ASA), and sodium diclofenac. The sodium or protonated CMS were obtained from the same CMS synthesis by controlling the final pH of reaction media. The two forms of CMS were confirmed by the Fourier transform infrared spectroscopy. The in vitro dissolution profiles for monolithic and double core tablets were different and allowed a better understanding of characteristics of the two excipient forms. It was found that the protonated CMS exhibited a better stability in simulated gastric fluid in comparison to its sodium salt in monolithic dosage forms, whereas both excipients afforded a complete gastric protection of drugs when formulated as dry-coated dosages. Determination of water uptake and erosion rate of monolithic matrices based on the two CMS forms showed different mechanisms involved in the delivery of the three model active molecules in simulated intestinal media. When pancreatic enzymes were added in dissolution media, the drug release was accelerated showing that CMS is still a substrate for alpha-amylase. Both sodium and protonated starch excipients, formulated as dry-coated dosages, afforded a good gastro-protection and allowed a drug chronodelivery at various intervals up to 4-5 h. They could be considered as an alternative for delayed delivery and a solvent-free coating procedure. PMID- 27686942 TI - Age differences in the takeover of vehicle control and engagement in non-driving related activities in simulated driving with conditional automation. AB - High-level vehicle automation has been proposed as a valuable means to enhance the mobility of older drivers, as older drivers experience age-related declines in many cognitive functions that are vital for safe driving. Recent research attempted to examine age differences in how engagement in non-driving-related activities impact driving performance, by instructing drivers to engage in mandatory pre-designed activities. While the mandatory engagement method allows a precise control of the timing and mental workload of the non-driving-related activities, it is different from how a driver would naturally engage in these activities. This study allowed younger (age 18-35, mean age=19.9years) and older drivers (age 62-81, mean age=70.4years) to freely decide when and how to engage in voluntarily chosen non-driving-related activities during simulated driving with conditional automation. We coded video recordings of participants' engagement in non-driving-related activities. We examined the effect of age, level of activity-engagement and takeover notification interval on vehicle control performance during the takeover, by comparing between the high and low engagement groups in younger and older drivers, across two takeover notification interval conditions. We found that both younger and older drivers engaged in various non-driving-related activities during the automated driving portion, with distinct preferences on the type of activity for each age group (i.e., while younger drivers mostly used an electronic device, older drivers tended to converse). There were also significant differences between the two age groups and between the two notification intervals on various driving performance measures. Older drivers benefited more than younger drivers from the longer interval in terms of response time to notifications. Voluntary engagement in non-driving related activities did not impair takeover performance in general, although there was a trend of older drivers who were more engaged in non-driving-related activities braking harder than those with low activity-engagement during the takeover. PMID- 27686943 TI - Health-related quality of life in patients with high-risk low-grade glioma (EORTC 22033-26033): a randomised, open-label, phase 3 intergroup study. AB - BACKGROUND: Temozolomide chemotherapy versus radiotherapy in patients with a high risk low-grade glioma has been shown to have no significant effect on progression free survival. If these treatments have a different effect on health-related quality of life (HRQOL), it might affect the choice of therapy. We postulated that temozolomide compromises HRQOL and global cognitive functioning to a lesser extent than does radiotherapy. METHODS: We did a prospective, phase 3, randomised controlled trial at 78 medical centres and large hospitals in 19 countries. We enrolled adult patients (aged >=18 years) with histologically confirmed diffuse (WHO grade II) astrocytoma, oligodendroglioma, or mixed oligoastrocytoma, with a WHO performance status of 2 or lower, without previous chemotherapy or radiotherapy, who needed active treatment other than surgery. We randomly assigned eligible patients (1:1) using a minimisation technique, stratified by WHO performance status (0-1 vs 2), age (<40 years vs >=40 years), presence of contrast enhancement on MRI, chromosome 1p status (deleted vs non-deleted vs indeterminate), and the treating medical centre, to receive either radiotherapy (50.4 Gy in 28 fractions of 1.8 Gy for 5 days per week up to 6.5 weeks) or temozolomide chemotherapy (75 mg/m2 daily, for 21 of 28 days [one cycle] for 12 cycles). The primary endpoint was progression-free survival (results published separately); here, we report the results for two key secondary endpoints: HRQOL (assessed using the European Organisation for Research and Treatment of Cancer's [EORTC] QLQ-C30 [version 3] and the EORTC Brain Cancer Module [QLQ-BN20]) and global cognitive functioning (assessed using the Mini-Mental State Examination [MMSE]). We did analyses on the intention-to-treat population. This study is closed and is registered at EudraCT, number 2004-002714-11, and at ClinicalTrials.gov, number NCT00182819. FINDINGS: Between Dec 6, 2005, and Dec 21, 2012, we randomly assigned 477 eligible patients to either radiotherapy (n=240) or temozolomide chemotherapy (n=237). The difference in HRQOL between the two treatment groups was not significant during the 36 months' follow-up (mean between group difference [averaged over all timepoints] 0.06, 95% CI -4.64 to 4.75, p=0.98). At baseline, 32 (13%) of 239 patients who received radiotherapy and 32 (14%) of 236 patients who received temozolomide chemotherapy had impaired cognitive function, according to the MMSE scores. After randomisation, five (8%) of 63 patients who received radiotherapy and three (6%) of 54 patients who received temozolomide chemotherapy and who could be followed up for 36 months had impaired cognitive function, according to the MMSE scores. No significant difference was recorded between the groups for the change in MMSE scores during the 36 months of follow-up. INTERPRETATION: The effect of temozolomide chemotherapy or radiotherapy on HRQOL or global cognitive functioning did not differ in patients with low-grade glioma. These results do not support the choice of temozolomide alone over radiotherapy alone in patients with high-risk low grade glioma.

PMID- 27686945 TI - Induction chemotherapy plus concurrent chemoradiotherapy versus concurrent chemoradiotherapy alone in locoregionally advanced nasopharyngeal carcinoma: a phase 3, multicentre, randomised controlled trial. AB - BACKGROUND: The value of adding cisplatin, fluorouracil, and docetaxel (TPF) induction chemotherapy to concurrent chemoradiotherapy in locoregionally advanced nasopharyngeal carcinoma is unclear. We aimed to compare TPF induction chemotherapy plus concurrent chemoradiotherapy with concurrent chemoradiotherapy alone in a suitably powered trial. METHODS: We did an open-label, phase 3, multicentre, randomised controlled trial at ten institutions in China. Patients with previously untreated, stage III-IVB (except T3-4N0) nasopharyngeal carcinoma, aged 18-59 years without severe comorbidities were enrolled. Eligible patients were randomly assigned (1:1) to receive induction chemotherapy plus concurrent chemoradiotherapy or concurrent chemoradiotherapy alone (three cycles of 100 mg/m2 cisplatin every 3 weeks, concurrently with intensity-modulated radiotherapy). Induction chemotherapy was three cycles of intravenous docetaxel (60 mg/m2 on day 1), intravenous cisplatin (60 mg/m2 on day 1), and continuous intravenous fluorouracil (600 mg/m2 per day from day 1 to day 5) every 3 weeks before concurrent chemoradiotherapy. Randomisation was by a computer-generated random number code with a block size of four, stratified by treatment centre and disease stage (III or IV). Treatment allocation was not masked. The primary endpoint was failure-free survival calculated from randomisation to locoregional failure, distant failure, or death from any cause; required sample size was 476 patients (238 per group). We did efficacy analyses in our intention-to-treat population. The follow-up is ongoing; in this report, we present the 3-year survival results and acute toxic effects. This trial is registered with ClinicalTrials.gov, number NCT01245959. FINDINGS: Between March 1, 2011, and Aug 22, 2013, 241 patients were assigned to induction chemotherapy plus concurrent chemoradiotherapy and 239 to concurrent chemoradiotherapy alone. After a median follow-up of 45 months (IQR 38-49), 3-year failure-free survival was 80% (95% CI 75-85) in the induction chemotherapy plus concurrent chemoradiotherapy group and 72% (66-78) in the concurrent chemoradiotherapy alone group (hazard ratio 0.68, 95% CI 0.48-0.97; p=0.034). The most common grade 3 or 4 adverse events during treatment in the 239 patients in the induction chemotherapy plus concurrent chemoradiotherapy group versus the 238 patients in concurrent chemoradiotherapy alone group were neutropenia (101 [42%] vs 17 [7%]), leucopenia (98 [41%] vs 41 [17%]), and stomatitis (98 [41%] vs 84 [35%]). INTERPRETATION: Addition of TPF induction chemotherapy to concurrent chemoradiotherapy significantly improved failure-free survival in locoregionally advanced nasopharyngeal carcinoma with acceptable toxicity. Long-term follow-up is required to determine long-term efficacy and toxicities.

PMID- 27686946 TI - Temozolomide chemotherapy versus radiotherapy in high-risk low-grade glioma (EORTC 22033-26033): a randomised, open-label, phase 3 intergroup study. AB - BACKGROUND: Outcome of low-grade glioma (WHO grade II) is highly variable, reflecting molecular heterogeneity of the disease. We compared two different, single-modality treatment strategies of standard radiotherapy versus primary temozolomide chemotherapy in patients with low-grade glioma, and assessed progression-free survival outcomes and identified predictive molecular factors. METHODS: For this randomised, open-label, phase 3 intergroup study (EORTC 22033 26033), undertaken in 78 clinical centres in 19 countries, we included patients aged 18 years or older who had a low-grade (WHO grade II) glioma (astrocytoma, oligoastrocytoma, or oligodendroglioma) with at least one high-risk feature (aged >40 years, progressive disease, tumour size >5 cm, tumour crossing the midline, or neurological symptoms), and without known HIV infection, chronic hepatitis B or C virus infection, or any condition that could interfere with oral drug administration. Eligible patients were randomly assigned (1:1) to receive either conformal radiotherapy (up to 50.4 Gy; 28 doses of 1.8 Gy once daily, 5 days per week for up to 6.5 weeks) or dose-dense oral temozolomide (75 mg/m2 once daily for 21 days, repeated every 28 days [one cycle], for a maximum of 12 cycles). Random treatment allocation was done online by a minimisation technique with prospective stratification by institution, 1p deletion (absent vs present vs undetermined), contrast enhancement (yes vs no), age (<40 vs >=40 years), and WHO performance status (0 vs >=1). Patients, treating physicians, and researchers were aware of the assigned intervention. A planned analysis was done after 216 progression events occurred. Our primary clinical endpoint was progression-free survival, analysed by intention-to-treat; secondary outcomes were overall survival, adverse events, neurocognitive function (will be reported separately), health-related quality of life and neurological function (reported separately), and correlative analyses of progression-free survival by molecular markers (1p/19q co-deletion, MGMT promoter methylation status, and IDH1/IDH2 mutations). This trial is closed to accrual but continuing for follow-up, and is registered at the European Trials Registry, EudraCT 2004-002714-11, and at ClinicalTrials.gov, NCT00182819. FINDINGS: Between Sept 23, 2005, and March 26, 2010, 707 patients were registered for the study. Between Dec 6, 2005, and Dec 21, 2012, we randomly assigned 477 patients to receive either radiotherapy (n=240) or temozolomide chemotherapy (n=237). At a median follow-up of 48 months (IQR 31-56), median progression-free survival was 39 months (95% CI 35-44) in the temozolomide group and 46 months (40-56) in the radiotherapy group (unadjusted hazard ratio [HR] 1.16, 95% CI 0.9-1.5, p=0.22). Median overall survival has not been reached. Exploratory analyses in 318 molecularly-defined patients confirmed the significantly different prognosis for progression-free survival in the three recently defined molecular low-grade glioma subgroups (IDHmt, with or without 1p/19q co-deletion [IDHmt/codel], or IDH wild type [IDHwt]; p=0.013). Patients with IDHmt/non-codel tumours treated with radiotherapy had a longer progression free survival than those treated with temozolomide (HR 1.86 [95% CI 1.21-2.87], log-rank p=0.0043), whereas there were no significant treatment-dependent differences in progression-free survival for patients with IDHmt/codel and IDHwt tumours. Grade 3-4 haematological adverse events occurred in 32 (14%) of 236 patients treated with temozolomide and in one (<1%) of 228 patients treated with radiotherapy, and grade 3-4 infections occurred in eight (3%) of 236 patients treated with temozolomide and in two (1%) of 228 patients treated with radiotherapy. Moderate to severe fatigue was recorded in eight (3%) patients in the radiotherapy group (grade 2) and 16 (7%) in the temozolomide group. 119 (25%) of all 477 patients had died at database lock. Four patients died due to treatment-related causes: two in the temozolomide group and two in the radiotherapy group. INTERPRETATION: Overall, there was no significant difference in progression-free survival in patients with low-grade glioma when treated with either radiotherapy alone or temozolomide chemotherapy alone. Further data maturation is needed for overall survival analyses and evaluation of the full predictive effects of different molecular subtypes for future individualised treatment choices.

PMID- 27686949 TI - Alkali-activated concrete with Serbian fly ash and its radiological impact. AB - The present paper reports the results of a study on different types of fly ash from Serbian coal burning power plants and their potential use as a binder in alkali-activated concrete (AAC) depending on their radiological and mechanical properties. Five AAC mixtures with different types of coal burning fly ash and one type of blast furnace slag were designed. Measurements of the activity concentrations of 40K, 226Ra and 232Th were done both on concrete constituents (fly ash, blast furnace slag and aggregate) and on the five solid AAC samples. Experimental results were compared by using the activity concentration assessment tool for building materials - the activity concentration index I, as introduced by the EU Basic Safety Standards (CE, 2014). All five designed alkali-activated concretes comply with EU BSS screening requirements for indoor building materials. Finally, index I values were compared with the results of the application of a more accurate index - I(rhod), which accounts for thickness and density of building materials (Nuccetelli et al., 2015a). Considering the actual density and thickness of each concrete sample index - I(rhod) values are lower than index I values. As an appendix, a synthesis of main results concerning mechanical and chemical properties is provided. PMID- 27686948 TI - Levodopa medication improves incidental sequence learning in Parkinson's disease. AB - Empirical evidence suggests that levodopa medication used to treat the motor symptoms of Parkinson's disease (PD) may either improve, impair or not affect specific cognitive processes. This evidence led to the 'dopamine overdose' hypothesis that levodopa medication impairs performance on cognitive tasks if they recruit fronto-striatal circuits which are not yet dopamine-depleted in early PD and as a result the medication leads to an excess of dopamine. This hypothesis has been supported for various learning tasks including conditional associative learning, reversal learning, classification learning and intentional deterministic sequence learning, on all of which PD patients demonstrated significantly worse performance when tested on relative to off dopamine medication. Incidental sequence learning is impaired in PD, but how such learning is affected by dopaminergic therapy remains undetermined. The aim of the current study was to investigate the effect of dopaminergic medication on incidental sequence learning in PD. We used a probabilistic serial reaction time task (SRTT), a sequence learning paradigm considered to make the sequence less apparent and more likely to be learned incidentally rather than intentionally. We compared learning by the same group of PD patients (n=15) on two separate occasions following oral administration of levodopa medication (on state) and after overnight withdrawal of medication (off state). Our results demonstrate for the first time that levodopa medication enhances incidental learning of a probabilistic sequence on the serial reaction time task in PD. However, neither group significantly differed from performance of a control group without a neurological disease, which indicates the importance of within group comparisons for identifying deficits. Levodopa medication enhanced incidental learning by patients with PD on a probabilistic sequence learning paradigm even though the patients were not aware of the existence of the sequence or their acquired knowledge. The results suggest a role in acquiring incidental motor sequence learning for dorsal striatal areas strongly affected by dopamine depletion in early PD.

AB - Osteoarthritis (OA), the most common type of arthritis worldwide, is a degenerative disease of diarthrodial joints resulting in pain, reduced quality of life, and socioeconomic burden. Gout, the most common form of inflammatory arthritis, is a consequence of persistently elevated levels of urate and the formation of proinflammatory monosodium urate crystals in joints. Clinicians have long noted a predilection for both diseases to occur in the same joints. In this review, we provide an overview into research elucidating possible biochemical, mechanical, and immunological relationships between gout and OA. We additionally consider the potential implications of these relationships for OA treatment. PMID- 27686953 TI - Congo fever rears its head again in Pakistan.

AB - This study evaluated the utility of items and scales from the Iowa Violence and Victimization Instrument in a sample of 1961 males from the state of Iowa who were on probation or released from prison to parole supervision. This is the first study to examine the potential of the Iowa Violence and Victimization Instrument to predict criminal offenses. The males were followed for 30months immediately following their admission to probation or parole. AUC analyses indicated fair to good predictive power for the Iowa Violence and Victimization Instrument for charges of violence and victimization, but chance predictive power for drug offenses. Notably, both scales of the instrument performed equally well at the 30-month follow-up. Items on the Iowa Violence and Victimization Instrument not only predicted violence, but are straightforward to score. Violence management strategies are discussed as they relate to the current findings, including the potential to expand the measure to other jurisdictions and populations.

AB - As bisphenol A (BPA) exerts oxidative/pro-apoptotic effects in several cell types, we explored whether the in vitro exposure to BPA could affect human sperm integrity through the induction of pro-oxidative/apoptotic mitochondrial dysfunction. The exposure of motile sperm suspensions to scalar BPA concentrations for 4h produced a decrease in the mitochondrial membrane potential, starting from 300MUM. It was associated with an increased mitochondrial generation of superoxide anion, caspase-9 and caspase-3 activation and motility decrement. Vitality decline was observed at BPA>=400MUM. Twenty hours exposure to 300MUM BPA, but not to lower concentrations, produced a significant loss in sperm vitality associated with a complete sperm immobilization. Finally, 300MUM BPA also produced a significant DNA oxidative damage, as revealed by the formation of oxidized base adduct 8-hydroxy-2' deoxyguanosine. In conclusion, BPA affected human sperm integrity by inducing pro oxidative/apoptotic mitochondrial dysfunction.

AB - Trehalose, a non-permeating cryoprotective agent (CPA), has been documented as less toxic and highly efficient at cryopreserving different kinds of cells or organisms. In the present study, trehalose was evaluated for its application in cryopreservation of both Trypanosoma brucei procyclic and bloodstream form cells. The cryopreservation efficiency was determined by the motility of trypanosomes after thawing, as well as a subsequent recovery and infectivity assessment. The viability of trypanosomes from cultivation that were frozen in a serial concentrations of trehalose showed similar results to classical CPAs of glycerol and DMSO. Nevertheless, trypanosomes cryopreserved in 0.2M trehalose showed the best growth characteristic during subsequent cultivation. In addition, CPA cocktails with trehalose and permeating CPA glycerol or DMSO were developed and evaluated. Interestingly, trypanosomes in host (mouse) blood cryopreserved in 0.4M trehalose plus 5% glycerol showed higher infectivity than those preserved in trehalose/DMSO cocktails as well as individually. Further investigations showed that, in comparison with slow freezing at -80 degrees C, flash freezing in liquid nitrogen provided better cryopreservation for bloodstream form cells than slow freezing. In conclusion, trehalose is an easy, safe and efficient CPA for cryopreservation of T. brucei and potentially for other protozoan species and cells. PMID- 27686959 TI - First detection and molecular identification of Babesia gibsoni from Rhipicephalus sanguineus ticks. AB - Babesia gibsoni was firstly identified in Rhipicephalus sanguineus ticks infested on dogs in Asia. A total of 1195 ticks collected from veterinary practitioners and pet clinics were examined for Babesia by nested-polymerase chain reaction assay based on the 18S small subunit ribosomal RNA (ssrRNA) gene. Babesia infection was detected in nymph, male and female ticks with an infection rate of 2.42%, 0.98% and 1.97%, respectively. Sequence and phylogenetic analysis revealed that these Babesia spp. were genetically affiliated to the same clades within the genospecies of B. gibsoni and B. vogeli, and can be discriminated from other genospecies of Babesia. Intra- and inter-species analysis based on the genetic distance (GD) values indicated a lower level in B. gibsoni (GD<0.011) compared with other genospecies of Babesia (GD>0.106) and out-group protozoa (GD>0.244). This study provides the first molecular evidence of B. gibsoni identified in nymphs of R. sanguineus ticks in Asia, and further confirms the detection of B. vogeli in nymphs and adults of R. sanguineus in northern Taiwan. The epizootiological significance of canine Babesia spp. transmitted by R. sanguineus tick needs to be further identified. PMID- 27686957 TI - The effect of Lucilia sericata- and Sarconesiopsis magellanica-derived larval therapy on Leishmania panamensis. AB - This study's main objective was to evaluate the action of larval therapy derived from Lucilia sericata and Sarconesiopsis magellanica (blowflies) regarding Leishmania panamensis using an in vivo model. Eighteen golden hamsters (Mesocricetus auratus) were used; they were divided into 6 groups. The first three groups consisted of 4 animals each; these, in turn, were internally distributed into subgroups consisting of 2 hamsters to be used separately in treatments derived from each blowfly species. Group 1 was used in treating leishmanial lesions with larval therapy (LT), whilst the other two groups were used for evaluating the used of larval excretions and secretions (ES) after the ulcers had formed (group 2) and before they appeared (group 3). The three remaining groups (4, 5 and 6), consisting of two animals, were used as controls in the experiments. Biopsies were taken for histopathological and molecular analysis before, during and after the treatments; biopsies and smears were taken for assessing parasite presence and bacterial co-infection. LT and larval ES proved effective in treating the ulcers caused by the parasite. There were no statistically significant differences between the blowfly species regarding the ulcer cicatrisation parameters. There were granulomas in samples taken from lesions at the end of the treatments. The antibacterial action of larval treatment regarding co-infection in lesions caused by the parasite was also verified. These results potentially validate effective LT treatment against cutaneous leishmaniasis aimed at using it with humans in the future. PMID- 27686960 TI - Kerteszia Theobald (Diptera: Culicidae) mosquitoes and bromeliads: A landscape ecology approach regarding two species in the Atlantic rainforest. AB - On the ecological scale of an organism, a homogeneous geographical landscape can represent a mosaic of heterogeneous landscapes. The bionomy of Kerteszia mosquitoes can contribute to foundation landscape ecology by virtue of in the role of the configuration and composition of the habitat played in the distribution of mosquito species. Thus, this study aimed: to compare the abundance of Kerteszia in dense tropical rainforest, restinga and rural area, to assess the bioecological characteristics of the main bromeliads hosting Kerteszia, and to associate the bioecological arrangement of the bromeliads with Kerteszia distribution. Field collections were conducted in a monthly schedule from December of 2010 to November 2011. The vegetation of landscapes was characterized on the basis of a digital cartographic database, the manual of the Brazilian vegetation, environmental atlas information, satellite images and visits to the sites. Multivariate generalized linear models were employed using the R-project statistical program. The results were: Anopheles cruzii was the most frequent species in dense tropical rainforest (67.42%), with a positive association (deviance=25.8; P=0.002). Anopheles bellator was more abundant in the Restinga area (78.97%), with a positive association (deviance=10.4, P=0.018). There was a positive aggregation of Restinga with An. bellator (RR=2.42) but a lower level with An. cruzii (RR=0.31). Thus we can conclude that landscape characteristics influence the distribution of Kerteszia mosquitoes. An. bellator has a higher prevalence in Restinga areas, whereas An. cruzii was the most prevalent in the dense tropical rainforest. PMID- 27686962 TI - Efficacy and safety of pharmacological treatments for Lyme neuroborreliosis in children: a systematic review. AB - BACKGROUND: Many aspects of pharmacological treatment of Lyme neuroborreliosis in children, such as choice of drug, dosage, and duration are subject to intense debates, leading to uncertainties in patients' parents and healthcare providers alike. To assess the available evidence for pharmacological treatment for children with Lyme neuroborreliosis we conducted a systematic review. METHODS: The comprehensive systematic literature search included randomized-controlled trials (RCTs) and non-randomized studies (NRS) on treatment of Lyme neuroborreliosis in children (age <18 years). Our primary outcome was neurological symptoms after treatment. Risk of bias was assessed with the Cochrane risk of bias tools for RCTs and NRS. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: Two RCTs and four NRS were eligible for inclusion. Risk of bias in RCTs and NRS was generally high. Reporting of studies was generally poor. Regarding the primary outcome neurological symptoms at 1-3 months, no statistically significant difference could be found in cohort studies between doxycycline and beta-lactam antibiotics. In two RCTs comparing penicillin G and ceftriaxone, no patient experienced residual neurological symptoms at the last reported time points. Quality of evidence according to GRADE was judged very low. CONCLUSIONS: Data is scarce and with limited quality. Several issues could not be addressed due to scarcity of information. No eligible study compared different treatment durations. According to the available evidence, there seems to be no difference between different antibiotic agents for the treatment of Lyme neuroborreliosis in children regarding neurological symptoms. We found no evidence that supports extended antibiotic regimes. REVIEW REGISTRATION: Systematic review registration: CRD42014008839 . PMID- 27686961 TI - Role of placental barrier integrity in infection by Trypanosoma cruzi. AB - American trypanosomiasis has long been a neglected disease endemic in LatinAmerica, but congenital transmission has now spread Chagas disease to cause a global health problem. As the early stages of the infection of placental tissue and the vertical transmission by Trypanosoma cruzi are still not well understood, it is important to investigate the relevance of the first structure of the placental barrier in chorionic villi infection by T. cruzi during the initial stage of the infection. Explants of human chorionic villi from healthy pregnant women at term were denuded of their syncytiotrophoblast and co-cultured for 3h, 24h and 96h with 800,000 trypomastigotes (simulating acute infection). T. cruzi infected cells were identified by immunohistochemistry for cytokeratin-7 (+cytotrophoblast) and CD68 (+macrophages), and the infection was quantified. In placental tissue, the parasite load was analyzed by qPCR and microscopy, and the motile trypomastigotes were quantified in culture supernatant. In denuded chorionic villous, the total area occupied by the parasite (451.23MUm2, 1.33%) and parasite load (RQ: 87) was significantly higher (p<0.05) than in the entire villous (control) (5.98MUm2, 0.016%) (RQ:1) and with smaller concentration of nitric oxide. Stromal non-macrophage cells were infected as well as cytotrophoblasts and some macrophages, but with significant differences being observed. The parasite quantity in the culture supernatant was significantly higher (p<0.05) in denuded culture explants from 96h of culture. Although the human complete chorionic villi limited the infection, the detachment of the first structure of the placenta barrier (syncytiotrophoblast) increased both the infection of the villous stroma and the living trypomastigotes in the culture supernatant. Therefore structural and functional alterations to chorionic villi placental barrier reduce placental defenses and may contribute to the vertical transmission of Chagas. PMID- 27686963 TI - Safety profile of biologic drugs in the therapy of Crohn disease: A systematic review and network meta-analysis. AB - BACKGROUND: Crohn disease (CD) is an inflammatory bowel disease which occurs especially in developed countries of Western Europe and North America. The aim of the study was to compare the safety profile of biologic drugs in patients with CD. METHODOLOGY: A systematic literature search was performed using PubMed, Embase, and CENTRAL databases, until April 27, 2016. We included randomized controlled trials (RCTs) that compared the safety of biologic drugs (infliximab, adalimumab, vedolizumab, certolizumab pegol, and ustekinumab) with one another or with placebo in patients with CD. The network meta-analysis (NMA) was conducted for an induction phase (6-10 weeks) and maintenance phase (52-56 weeks) with a Bayesian hierarchical random effects model in the ADDIS(r) software. The PROSPERO registration number was CRD42016032606. RESULTS: Ten RCTs were included in the systematic review with NMA. In the case of the induction phase, the NMA could be conducted for the assessment of the relative safety profile of adalimumab, vedolizumab, certolizumab pegol, and ustekinumab, and in the case of the maintenance phase-of infliximab, adalimumab, and vedolizumab. There were no significant differences in the rate of adverse events in patients treated with biologics. Statistical analysis revealed that vedolizumab had the greatest probability of being the safest treatment in most endpoints in the induction phase and adalimumab-in the maintenance phase. CONCLUSIONS: No significant differences between the biologics in the relative safety profile analysis were observed. Further studies are needed to confirm our findings, including head-to head comparisons between the analyzed biologics. PMID- 27686964 TI - The antifibrotic effects of alveolar macrophages 5-HT2C receptors blockade on bleomycin-induced pulmonary fibrosis in rats. AB - BACKGROUND: The most widespread chronic fibrosing lung disease is idiopathic pulmonary fibrosis. Lung serotonin (5-HT) content is increased during pulmonary fibrosis with the implication of 5-HT2 receptors in the pathogenesis. Serotonin plays important roles in alveolar macrophages function through 5-HT2C receptors activation. Numerous studies described the important role of 5-HT2A/B receptor blockers in suppressing different types of fibrosis as idiopathic pulmonary fibrosis. The current study pointed to examine the antifibrotic effects of RS 102221 and/or terguride through in vivo model of pulmonary fibrosis. METHODS: Induction of pulmonary fibrosis was through a single dose of intra-tracheal bleomycin instillation (5mg/kg dissolved in phosphate buffer saline) in adult male albino Wistar rats. Next day of bleomycin instillation, intraperitoneal injection of RS-102221 (0.5mg/kg/d) and/or terguride (1.2mg/kg/d) were administered and continued for 14 days. RESULTS: Noticeable increase in 5-HT2C receptors expression was observed in fibrotic lung tissues with marked allocation belonging to alveolar macrophages. Either RS-102221 or terguride reduced the increments in lung water contents, grading of lung fibrosis, lung tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta1 (TGF-beta1) and vascular endothelial growth factor (VEGF) levels in lung injury and fibrosis induced by bleomycin. Moreover, collagen content and myofibroblasts-alpha smooth muscle actin (alpha-SMA) were significantly decreased. Additionally, the simultaneous administration of RS-102221 with terguride had a synergistic outcome compared to that obtained by individual monotherapy. CONCLUSION: These findings suggested the potential use of 5-HT2A/B/C antagonists as anti-fibrotic agents in lung fibrosis. PMID- 27686965 TI - Benzimidazole-core as an antimycobacterial agent. AB - Mycobacterium tuberculosis (Mtb) is considered as one of the precarious bacterial infections around the world. Through a projected 8.7 million new tuberculosis (TB) cases and 1.4 million mortalities per annum, this deadly infection resulted insubstantial amount of human deaths than any other single organism bacterial infections. TB is one of India's most threatening human health problems and it accounts for approximately 33% of the global health issues. Subsequently, for TB there is an imperative need for the improvement of existing drug candidates with newer targets and specified mechanism of action. Within the wide spectra of heterocycles, benzimidazole and its substituted analogues were evidenced promising biological efficacies enabling them to perform as new drug or prodrug candidates. Exceptional structural features of this class of heterocycle and versatile biological applications made it a privileged structural backbone in new drug design and discovery. Majorly, 2,5- and 2,6-disubstituted benzimidazole derivatives shown to induce significant antiTB potential. To seek more insights on this unique feature of benzimidazole candidates, there is an urgency to assemble the recent advances in this promising area. This review presents an overview of the recent advancements and focuses on the structural features responsible for unique antiTB applications and compiled published reports on benzimidazole derivatives emphasizing on different approaches employed for their syntheses in order to help medicinal and clinical chemists in designing next generation, yet effective and safer antiTB candidates. PMID- 27686966 TI - Combretastatins: In vitro structure-activity relationship, mode of action and current clinical status. AB - For the first time combretastatins were isolated from African willow tree Combretum Caffrum. Subsequent studies have shown the impact of combretastatin A4 phosphate, a water-soluble prodrug, on endothelial cells in tumor vascular system. The same effect was not observed in the vascular system. This selectivity is associated with combretastatins mechanism of action: binding to colchicine domain of microtubules, which affects the cytoskeleton functionality of immature endothelial cells. At the same time, combretastatins directly induce cell death via apoptosis and/or mitotic catastrophe pathways. The combination of both elements makes combretastatin an anticancer compound of high efficiency. The cis configuration is crucial for its biological activity. To date, many derivatives were synthesized. The attempts to resolve spontaneous isomerization to less active trans-stilbene derivative are still in progress. This issue seems to be overcome by incorporation of the ethene bridge with heterocyclic moiety in combretastatins structure. This modification retains the cis-configuration and prevents isomerization. Nevertheless, combretastatin A4 phosphate disodium is still the most potent compound of this group. The combination therapy, which is the most effective treatment, includes combretastatin A4 phosphate (CA4P) and conventional chemotherapeutics and/or radiotherapy. CA4P is relatively well tolerated giving adverse events of moderate severity, which includes: nausea, vomiting, headache, and tumor pain. The aforementioned effects subside on the day of drug administration or on the following day. PMID- 27686968 TI - Stereotactic Body Radiotherapy Virtual Special Issue. PMID- 27686967 TI - Rapamycin negatively impacts insulin signaling, glucose uptake and uncoupling protein-1 in brown adipocytes. AB - New onset diabetes after transplantation (NODAT) is a metabolic disorder that affects 40% of patients on immunosuppressive agent (IA) treatment, such as rapamycin (also known as sirolimus). IAs negatively modulate insulin action in peripheral tissues including skeletal muscle, liver and white fat. However, the effects of IAs on insulin sensitivity and thermogenesis in brown adipose tissue (BAT) have not been investigated. We have analyzed the impact of rapamycin on insulin signaling, thermogenic gene-expression and mitochondrial respiration in BAT. Treatment of brown adipocytes with rapamycin for 16h significantly decreased insulin receptor substrate 1 (IRS1) protein expression and insulin-mediated protein kinase B (Akt) phosphorylation. Consequently, both insulin-induced glucose transporter 4 (GLUT4) translocation to the plasma membrane and glucose uptake were decreased. Early activation of the N-terminal Janus activated kinase (JNK) was also observed, thereby increasing IRS1 Ser 307 phosphorylation. These effects of rapamycin on insulin signaling in brown adipocytes were partly prevented by a JNK inhibitor. In vivo treatment of rats with rapamycin for three weeks abolished insulin-mediated Akt phosphorylation in BAT. Rapamycin also inhibited norepinephrine (NE)-induced lipolysis, the expression of peroxisome proliferator-activated receptor gamma coactivator 1alpha (PGC-1alpha) and uncoupling protein (UCP)-1 in brown adipocytes. Importantly, basal mitochondrial respiration, proton leak and maximal respiratory capacity were significantly decreased in brown adipocytes treated with rapamycin. In conclusion, we demonstrate, for the first time the important role of brown adipocytes as target cells of rapamycin, suggesting that insulin resistance in BAT might play a major role in NODAT development.

PMID- 27686970 TI - Effect of Thoracic Radiotherapy Timing and Fractionation on Survival in Nonmetastatic Small Cell Lung Carcinoma. AB - BACKGROUND: The optimal timing of thoracic radiation therapy (RT) in relation to chemotherapy is unknown in the treatment of nonmetastatic small cell lung cancer (SCLC). We analyzed the National Cancer Data Base (NCDB) to assess the effect on overall survival (OS) of RT timing with chemotherapy for patients with SCLC. MATERIALS AND METHODS: The NCDB was queried for patients diagnosed with nonmetastatic SCLC from 1998 to 2011 who had undergone definitive chemoradiation. The patients were stratified into quartiles according to the interval between the start of chemotherapy and the start of RT. The first and second quartiles (RT started 0-20 days after chemotherapy) were classified as "early" RT and the third and fourth quartiles (RT started 21-126 days after chemotherapy) as "late" RT. Patients were included if they had received hyperfractionated 45 Gy in 30 fractions or standard fractionation of >= 60 Gy in 1.8- to 2-Gy fractions. Kaplan Meier analyses of OS were performed, and multivariable Cox regression analysis was conducted to assess the effect of the covariates on OS. RESULTS: A total of 8391 patients were included (50.5% had received early RT). Early RT was associated with significant improvement in survival (5-year OS, 21.9% vs. 19.1%; P = .01). On subgroup analysis, the survival advantage for early RT was significant for patients receiving hyperfractionated RT (5-year OS, 28.2% vs. 21.2%; P = .004) but not for those receiving standard fractionation (19.8% vs. 18.4%; P = .29). On multivariable Cox regression analysis, hyperfractionated RT was associated with reduced mortality (hazard ratio [HR], 0.90; 95% confidence interval [CI], 0.85-0.96; P = .001), but early RT was not (HR, 0.98; 95% CI, 0.94 1.04; P = .53). CONCLUSION: These data support the early initiation of hyperfractionated thoracic RT for nonmetastatic SCLC. PMID- 27686972 TI - L-DOPA in the hu man ovarian follicular fluid acts as an antioxidant factor on granulosa cells. AB - BACKGROUND: A previous study showed that dopamine (DA), which is contained in follicular fluid (FF) from IVF patients, strongly increased the production of reactive oxygen species (ROS) by cultured human granulosa cells (GCs). ROS, including H2O2, are assumed to play roles in ovarian physiology and pathology. Ovarian DA could be derived from the circulation, ovarian innervation and/or unknown ovarian sources. L-DOPA is the direct precursor of DA in its synthetic pathway. It was not yet described in FF. We examined L-DOPA levels in FF from IVF patients. As it may exert anti-oxidative and ROS-scavenging functions, we studied whether it exerts such actions in human GCs and whether DOPA-decarboxylase (DDC), the enzyme converting L-DOPA to DA, is expressed in the human ovary. RESULTS: ELISA measurements revealed that human IVF-derived FF contains L-DOPA. In cultured human GCs automated confluence analyses showed that L-DOPA enhanced their survival. This is in contrast to the actions of DA, which reduced cell survival. A dose-dependent mode of action of L-DOPA was identified using a fluorescent ROS indicator. The results showed that it antagonized intracellular ROS accumulation induced by exogenous H2O2. DDC was absent in follicular GCs, but immunohistochemistry identified it in theca cells (TCs) of large follicles in the human ovary. Laser micro-dissection followed by RT-PCR corroborated the expression. DDC was also identified in the steroidogenic cells of the corpus luteum. CONCLUSIONS: L-DOPA in FF is an antioxidant factor and exerts positive influences on GCs. Ovarian DA is derived from L-DOPA and has opposite actions. Exogenous L-DOPA is a standard therapy for Parkinson's disease, and the results raise the possibility that it may be able to exert positive actions as an antioxidant in ovarian conditions, as well. PMID- 27686971 TI - Phase 2 Study of Erlotinib in Combination With Linsitinib (OSI-906) or Placebo in Chemotherapy-Naive Patients With Non-Small-Cell Lung Cancer and Activating Epidermal Growth Factor Receptor Mutations. AB - INTRODUCTION: First-line epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor treatment of advanced non-small-cell lung cancer with EGFR-activating mutations improves outcomes compared with chemotherapy, but resistance develops in most patients. Compensatory signaling through type 1 insulin-like growth factor 1 receptor (IGF-1R) may contribute to resistance; dual blockade of IGF-1R and EGFR may improve outcomes. PATIENTS AND METHODS: We performed a randomized, double-blind, placebo-controlled phase II study of linsitinib, a dual IGF-1R and insulin receptor tyrosine kinase inhibitor, plus erlotinib versus placebo plus erlotinib in chemotherapy-naive patients with EGFR-mutation positive, advanced non-small-cell lung cancer. Patients received linsitinib 150 mg twice daily or placebo plus erlotinib 150 mg once daily on continuous 21-day cycles. The primary end point was progression-free survival. RESULTS: After randomization of 88 patients (44 each arm), the trial was unblinded early owing to inferiority in the linsitinib arm. The median progression-free survival for the linsitinib versus the placebo group was 8.4 months versus 12.4 months (hazard ratio, 1.37; P = .29). Overall response rate (47.7% vs. 75.0%; P = .02) and disease control rate (77.3% vs. 95.5%; P = .03) were also inferior. Whereas most adverse events were <= grade 2, linsitinib plus erlotinib was associated with increased adverse events that led to decreased erlotinib exposure (median days, 228 vs. 305). No drug-drug interaction was suggested by pharmacokinetic and pharmacodynamic results. CONCLUSION: Adding linsitinib to erlotinib resulted in inferior outcomes compared with erlotinib alone. Further understanding of the signaling pathways and a biomarker that can predict efficacy is needed prior to further clinical development of IGF-1R inhibitors in lung cancer.

AB - The present study demonstrates that one-step peptide backbone fragmentations can be achieved using the TEMPO [2-(2,2,6,6-tetramethyl piperidine-1-oxyl)]-assisted free radical-initiated peptide sequencing (FRIPS) mass spectrometry in a hybrid quadrupole time-of-flight (Q-TOF) mass spectrometer and a Q-Exactive Orbitrap instrument in positive ion mode, in contrast to two-step peptide fragmentation in an ion-trap mass spectrometer (reference Anal. Chem. 85, 7044-7051 (30)). In the hybrid Q-TOF and Q-Exactive instruments, higher collisional energies can be applied to the target peptides, compared with the low collisional energies applied by the ion-trap instrument. The higher energy deposition and the additional multiple collisions in the collision cell in both instruments appear to result in one-step peptide backbone dissociations in positive ion mode. This new finding clearly demonstrates that the TEMPO-assisted FRIPS approach is a very useful tool in peptide mass spectrometry research. Graphical Abstract ?. PMID- 27686976 TI - Highlights of WHO's work in the Eastern Mediterranean Region. PMID- 27686975 TI - Plasma triglyceride and high density lipoprotein cholesterol are poor surrogate markers of pro-atherogenic chylomicron remnant homeostasis in subjects with the metabolic syndrome. AB - BACKGROUND: Subjects with metabolic syndrome (MetS) exhibit impaired lipoprotein metabolism and have an increased risk of cardiovascular disease. Although the risk is attributed primarily to the risk associated with individual components, it is also likely affected by other associated metabolic defects. Remnants of postprandial lipoproteins show potent atherogenicity in cell and animal models of insulin resistance and in pre-diabetic subjects with postprandial dyslipidemia. However, few studies have considered regulation of chylomicron remnant homeostasis in MetS per se. This study measured the plasma concentration in Caucasian men and women of small dense chylomicrons following fasting and explored associations with metabolic and anthropometric measures. METHODS: A total of 215 Australian Caucasian participants (median age 62 years) were investigated. Of them, 40 participants were classified as having MetS. Apolipoprotein (apo) B-48, an exclusive marker of chylomicrons, metabolic markers and anthropometric measures were determined following an overnight fast. RESULTS: The fasting apo B-48 concentration was 40 % higher in subjects with MetS than those without MetS. In all subjects, triglyceride (r = 0.445, P < 0.0005), non HDL cholesterol (r = 0.28, P < 0.0005) and HDL cholesterol concentration (r = 0.272, P < 0.0005) were weakly associated with apo B-48 concentration. In subjects with MetS, the association of apo B-48 with triglyceride and non-HDL cholesterol was enhanced, but neither were robust markers of elevated apo B-48 in MetS (r = 0.618 and r = 0.595 respectively). There was no association between apo B-48 and HDL cholesterol in subjects with MetS. CONCLUSION: This study demonstrates a substantial accumulation of pro-atherogenic remnants in subjects with MetS. We have shown that in a Caucasian cohort, the fasting plasma concentration of triglyceride or HDL/non-HDL cholesterol serves as poor surrogate markers of atherogenic chylomicron remnants. These findings suggest that subjects with MetS exhibit a chronic defect in chylomicron metabolism that is likely to contribute to their increased CV risk.

AB - The study was conducted to determine the family, social and economic factors associated with deaths of children aged under 5 years. A registry-based nested case-control study was conducted of the deaths of all children aged under 5 years in Kohgilooyeh and Boyer-Ahmad Province in the Islamic Republic of Iran. For each death, two controls were randomly selected among children of the same age, sex and place of residence (186 cases and 372 controls). Congenital abnormality (37.6%) and preterm birth (29.0%) were the two most frequent causes of death among children aged under 5 years. No vaccine-preventable disease was reported as the cause of death. The strongest associations were found with consanguinity of the parents (OR = 3.92; 95% CI = 2.27-6.85 for being first cousins in comparison with no family relation; P < 0.001) and with domestic violence to the mother during pregnancy (OR = 3.13; 95% CI = 1.60-6.17; P < 0.01). The main causes of death of children aged under 5 years in the Province were congenital abnormality and prematurity. PMID- 27686978 TI - Collaboration between pharmacists and general practitioners in the health care system in the Islamic Republic of Iran. AB - Collaboration between pharmacists and general practitioners (GPs) has been shown to enhance patient care and outcomes. The aim of the present study was to investigate the collaborative working relationship between pharmacists and GPs in terms of their attitudes, role perceptions, experience with collaborative practice, preferred method of communication, areas of current and further collaboration, and perceived barriers to interprofessional collaboration in a sample of the Iranian population. We distributed 318 questionnaires to community pharmacists and GPs in Tehran. Both groups had a positive attitude towards collaboration; however, about half the respondents reported only occasional collaborative practice. Both groups preferred communication by telephone or face toface communication by fax or letter. Few current areas of collaboration were identified; however, an area favoured by both groups was "decision-making for patients' pharmacotherapy". The two groups expressed concern about possible fragmentation of patient care with the involvement of multiple health care providers, and perceived lack of face-to-face communication as a possible barrier to collaboration. PMID- 27686979 TI - Direct-to-consumer advertising for pharmaceuticals in Jordan from a gender perspective. AB - This study aimed to investigate the extent to which direct-to-consumer advertising (DTCA) for pharmaceuticals is disseminated in Jordan and to identify subsequent gender differences. The study was conducted on two samples: 1) patients (drug consumers) attending Jordan University Hospital, and 2) physicians working at the hospital (prescribers). A questionnaire was distributed to male and female patients (n=550), and based on its results a second questionnaire was designed and distributed to male and female physicians (n=200). The response rate was 93% for patients and 72% for physicians. Although the Jordanian Drug and Pharmacy Law prohibits the public promotion of medicines, consumers remain exposed to pharmaceutical advertising. The top ten drug classes advertised directly to consumers in Jordan included prescription-only drugs. Approximately 45% of the two samples agreed that women were more likely to be targeted by DTCA, while only 2% of them believed that men are more likely to be targeted. However, there was no statistically significant gender difference in attitudes towards pharmaceutical DTCA and tools used. PMID- 27686980 TI - Burden and associated factors for caregivers of the elderly in a developing country. AB - The elderly population in South Asia is growing. In Pakistan trained caregivers are scarce and culturally not acceptable. This study assessed the level of stress experienced by caregivers of the elderly and determined the association of care giving burden with different characteristics of the elderly. A cross-sectional, questionnaire based study was conducted using nonprobability purposive sampling. All consenting participants aged 60 years and above needing help with at least one activity of daily living or two instrumental activities of daily living were included. 350 participants were assessed for perceived care giver burden. Care providers were mostly female (68.9%). Half (50.3%) of the caregivers had a positive score on a perceived care burden scale. Financial impact had a strong correlation (0.79) with perceived caregiver burden. Higher dependency levels of a physical and cognitive nature posed greater burden on caregivers. Behavioural issues of the elderly such as verbal abuse and difficulty sleeping were predictors of a higher caregiver burden. Caregiver burden is a significant issue for those caring for elderly family members in Karachi, Pakistan.

AB - No study has investigated the availability and adherence of preventive oral care products on the Syrian market to evidence-based international recommendations. Data were collected in 2012, and updated in 2016, in terms of availability, characteristics and adherence to evidence-based international recommendations. Few preventive products adhered to the recommendations. Despite the large decrease in the number of oral care products on the Syrian market, due to the Syrian crisis, nonadherence of some of the available products is still present. A multisectorial approach at a policy level is needed to address such important limitations. The Syrian Ministry of Health should reform regulations for fluoride products to become subject to drug monitoring systems; the Syrian Arab Committee for Measurements and Standards needs to update its standards; and the Syrian General Dental Association should distribute a preventive booklet to dental practitioners.

AB - This study assessed the association between oral health knowledge and practices of pregnant Saudi women selected from visitors to a government hospital in Dammam, Saudi Arabia in 2014. Women answered questions on oral health knowledge during pregnancy and knowledge of infant oral health. Most women (> 70%) knew that dental caries in children can be prevented, that pregnancy affects oral health and that dental treatment during pregnancy can negatively affect infants. Most women (> 80%) performed oral hygiene procedures but only 18% regularly visited the dentist. In a regression analysis, oral health knowledge was not significantly associated with reported oral hygiene practices. Women who visited the dentist regularly were more likely to know how to prevent caries in children, and that dental treatment during pregnancy and infant health were associated.

AB - Palestinian refugees served by the United Nation Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) are experiencing increasing rates of diagnosis of non-communicable diseases. In response, in 2011 UNRWA initiated an Agency-wide programme of primary healthcare reform, informed by the Chronic Care Model framework. Health services were reorganized following a family-centred approach, with delivery by multidisciplinary family health teams supported by updated technical advice. An inclusive clinical information system, termed e Health, was implemented to collect a wide range of health information, with a focus on continuity of treatment. UNRWA was able to bring about these wide ranging changes within its existing resources, reallocating finances, reforming its payment mechanisms, and modernizing its drug-procurement policies. While specific components of UNRWA's primary healthcare reform are showing promising results, additional efforts are needed to empower patients further and to strengthen involvement of the community. PMID- 27686984 TI - Microplastic fragments and microbeads in digestive tracts of planktivorous fish from urban coastal waters. AB - We investigated microplastics in the digestive tracts of 64 Japanese anchovy (Engraulis japonicus) sampled in Tokyo Bay. Plastic was detected in 49 out of 64 fish (77%), with 2.3 pieces on average and up to 15 pieces per individual. All of the plastics were identified by Fourier transform infrared spectroscopy. Most were polyethylene (52.0%) or polypropylene (43.3%). Most of the plastics were fragments (86.0%), but 7.3% were beads, some of which were microbeads, similar to those found in facial cleansers. Eighty percent of the plastics ranged in size from 150 MUm to 1000 MUm, smaller than the reported size range of floating microplastics on the sea surface, possibly because the subsurface foraging behavior of the anchovy reflected the different size distribution of plastics between surface waters and subsurface waters. Engraulis spp. are important food for many humans and other organisms around the world. Our observations further confirm that microplastics have infiltrated the marine ecosystem, and that humans may be exposed to them. Because microplastics retain hazardous chemicals, increase in fish chemical exposure by the ingested plastics is of concern. Such exposure should be studied and compared with that in the natural diet.

The purpose of the study presented was to use Stattin and Kerr's (2000) monitoring subscales for the first time in a German-speaking area and to explore the relations to behaviour problems in an adolescent school sample. The two active monitoring strategies "parental control" and "parental solicitation" as well as "parental knowledge" and "child disclosure" relating to behaviour problems and risk behaviour were examined. A sample of 494 pupils, grades 5, 7 and 9, of German secondary schools and their parents answered questions on "parental knowledge", "control", "solicitation" and "child disclosure". Adolescents also answered the German version of the Strengths and Difficulties Questionnaire (SDQ) and items about risk behaviour like frequency of violence, delinquency, substance abuse, self-injuring behaviour and school absenteeism. Behaviour problems in terms of the SDQ could be predicted sufficiently by "parental knowledge", but for the prediction of risk behaviour, the active parental monitoring strategies were of importance, too. More "parental knowledge", more "control" and less "solicitation" could predict less risk behaviour. Results confirm "parental knowledge" as a general protective factor for problem behaviour. However, they show the importance of "parental control" for adolescent risk behaviour.

AB - Social-Emotional Competence in Young Children with Hearing, Visual or Intellectual Impairments - an Explorative Study with the ITSEA Early emotional and social competence is considered as an important requirement for social participation in family and child care settings. We report on a study exploring the usefulness of the competence scales as a part of the "Infant-Toddler Social and Emotional Assessment" (ITSEA) for one- to three-year old children in a sample of 253 toddlers with hearing, visual or intellectual impairments. Internal consistency of the six scales is good (alpha > .86). An ANOVA reveals significant differences between the three groups and a correlation with additional disabilities. These explorative results support the development of a German standardization of the ITSEA. PMID- 27686988 TI - [The Therapy Process of Accompanying Mothers in Multiple Family Therapy Groups: Evidence from a German Child Psychiatric Setting]. AB - The Therapy Process of Accompanying Mothers in Multiple Family Therapy Groups: Evidence from a German Child Psychiatric Setting This study provides an empirical contribution to the understanding of parents that accompany their children in psychiatric multiple family therapy settings (MFT). To this end, we conducted qualitative interviews with mothers that had successfully participated, with their diagnosed children (ages 3 to 9), in disorder-independent, age-homogeneous, and open family groups (the "Magdeburg Model") for several months. We performed a theoretical coding approach to the extensive interview material (n = 6 interviews, duration = 70 to 100 minutes each) according to Grounded Theory and extracted seven main and 29 sub-categories. These categories yield a coherent, complete, and specific subjective therapy model for this setting. One of the central findings is a profound understanding of to what extent and by which means the family group as a social arena paves and supports the arrival of the mothers in the group, their engagement into the therapy process, and their motivational and volitional steps during therapy. Another relevant result is a reconstruction of what we termed Arriving Home, which is the epitome of the positive cognitive, affective, and behavioral therapeutic development that mothers perceive. Conclusions for clinical practice as well as for qualitative and mixed methods therapy research are discussed. PMID- 27686995 TI - Conscientious objection in healthcare, referral and the military analogy. AB - An analogy is sometimes drawn between the proper treatment of conscientious objectors in healthcare and in military contexts. In this paper, I consider an aspect of this analogy that has not, to my knowledge, been considered in debates about conscientious objection in healthcare. In the USA and elsewhere, tribunals have been tasked with the responsibility of recommending particular forms of alternative service for conscientious objectors. Military conscripts who have a conscientious objection to active military service, and whose objections are deemed acceptable, are required either to serve the military in a non-combat role, or assigned some form of community service that does not contribute to the effectiveness of the military. I argue that consideration of the role that military tribunals have played in determining the appropriate form of alternative service for conscripts who are conscientious objectors can help us to understand how conscientious objectors in healthcare ought to be treated. Additionally, I show that it helps us to address the vexed issue of whether or not conscientious objectors who refuse to provide a service requested by a patient should be required to refer that patient to another healthcare professional.

It outlines civic republican concerns about the domination that arises from subjection to an arbitrary power of interference, while suggesting republican remedies to such domination in healthcare. These include proposals for greater review, challenge and pre-authorisation of medical power. It extends this analysis by providing a civic republican account of assistive arbitrary power, showing how it can create similar problems within both formal and informal relationships of care, and offering strategies for tackling it. Two important objections to civic republican medical ethics-that it overvalues independence and political participation in healthcare-are also considered and rebutted.

PMID- 27687000 TI - Changes in antioxidant and antibacterial activities as well as phytochemical constituents associated with ginger storage and polyphenol oxidase activity. AB - BACKGROUND: Herbal materials should be stored at optimal conditions in order to retain their nutritional quality. Proper storage has a significant impact on the quality of the herbs and spices. METHODS: The effects of storage temperature (5 and 15 degrees C) and time (4 and 8 months) on the phytochemical constituents associated with the antioxidant and antibacterial activities of ginger varieties (Halia bentong and Halia bara) were evaluated to determine the optimal storage conditions for ginger rhizomes. Total flavonoid content (TFC) and Total phenolic content (TPC) were measured using the spectrophotometric method. Individual phenolic acids and flavonoids, 6-gingerol and 6-shogaol were identified by ultra high performance liquid chromatography. Ferric reducing antioxidant potential (FRAP) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays were used for evaluation of antioxidant activities. An antibacterial property of ginger varieties was evaluated using well diffusion method. RESULTS: Dry matter, TPC, TFC and individual phenolics and flavonoids content, 6-gingerol and 6-shogaol content noticeably decreased at 5 and 15 degrees C during the storage times from 4 to 8 months. Highest content of flavonoids, phenolic acids, 6-gingerol, and 6-shogaol was observed in fresh samples followed by rhizomes stored at 5 degrees C for 4 months. Storage at 15 degrees C for 4 months reduced the phytochemical content significantly. Cinnamic acid and tannic acid were not detected in those variety stored at 15 degrees C for 4 and 8 months. Polyphenol oxidase (PPO) activity was associated significantly with storage time and temperature. Highest and lowest PPO activity was observed in stored and fresh rhizomes respectively. Antioxidant and antimicrobial activities gradually declined with the increase of storage temperature (from 5 to 15 degrees C) and duration (from 4 to 8 months) in both the varieties. Freshly harvested Halia bara variety had higher antioxidant and antibacterial activity compared to the Halia bentong variety. CONCLUSIONS: Halia bara exhibited valuable phytochemical content and antioxidant and antibacterial activities at higher levels compared to that exhibited by Halia bentong rhizomes. In general, storage of Malaysian ginger varieties at temperature of 5 degrees C is recommended and the storage time should be not more than 4 months. This storage condition will provide greater stability to the concentration of the phytochemical constituents more similar to the fresh material. PMID- 27686998 TI - Spatiotopic updating facilitates perception immediately after saccades. AB - As the neural representation of visual information is initially coded in retinotopic coordinates, eye movements (saccades) pose a major problem for visual stability. If no visual information were maintained across saccades, retinotopic representations would have to be rebuilt after each saccade. It is currently strongly debated what kind of information (if any at all) is accumulated across saccades, and when this information becomes available after a saccade. Here, we use a motion illusion to examine the accumulation of visual information across saccades. In this illusion, an annulus with a random texture slowly rotates, and is then replaced with a second texture (motion transient). With increasing rotation durations, observers consistently perceive the transient as large rotational jumps in the direction opposite to rotation direction (backward jumps). We first show that accumulated motion information is updated spatiotopically across saccades. Then, we show that this accumulated information is readily available after a saccade, immediately biasing postsaccadic perception. The current findings suggest that presaccadic information is used to facilitate postsaccadic perception and are in support of a forward model of transsaccadic perception, aiming at anticipating the consequences of eye movements and operating within the narrow perisaccadic time window.

AB - Photothermal therapy (PTT) offers many advantages such as high efficiency and minimal invasiveness, but clinical adoption of PTT nanoagents have been stifled by unresolved concerns such as the biodegradability as well as long-term toxicity. Herein, poly (lactic-co-glycolic acid) (PLGA) loaded with black phosphorus quantum dots (BPQDs) is processed by an emulsion method to produce biodegradable BPQDs/PLGA nanospheres. The hydrophobic PLGA not only isolates the interior BPQDs from oxygen and water to enhance the photothermal stability, but also control the degradation rate of the BPQDs. The in vitro and in vivo experiments demonstrate that the BPQDs/PLGA nanospheres have inappreciable toxicity and good biocompatibility, and possess excellent PTT efficiency and tumour targeting ability as evidenced by highly efficient tumour ablation under near infrared (NIR) laser illumination. These BP-based nanospheres combine biodegradability and biocompatibility with high PTT efficiency, thus promising high clinical potential. PMID- 27687002 TI - A picture is worth a thousand data points: an imagery dataset of paired shrub open microsites within the Carrizo Plain National Monument. AB - BACKGROUND: Carrizo Plain National Monument (San Joaquin Desert, California, USA) is home to many threatened and endangered species including the blunt-nosed leopard lizard (Gambelia sila). Vegetation is dominated by annual grasses, and shrubs such as Mormon tea (Ephedra californica), which is of relevance to our target species, the federally listed blunt-nosed leopard lizard, and likely also provides key ecosystem services. We used relatively nonintrusive camera traps, or trail cameras, to capture interactions between animals and these shrubs using a paired shrub-open deployment. Cameras were placed within the shrub understory and in open microhabitats at ground level to estimate animal activity and determine species presence. FINDINGS: Twenty cameras were deployed from April 1st, 2015 to July 5th, 2015 at paired shrub-open microsites at three locations. Over 425,000 pictures were taken during this time, of which 0.4 % detected mammals, birds, insects, and reptiles including the blunt-nosed leopard lizard. Trigger rate was very high on the medium sensitivity camera setting in this desert ecosystem, and rates did not differ between microsites. CONCLUSIONS: Camera traps are an effective, less invasive survey method for collecting data on the presence or absence of desert animals in shrub and open microhabitats. A more extensive array of cameras within an arid region would thus be an effective tool to estimate the presence of desert animals and potentially detect habitat use patterns. PMID- 27687001 TI - Various nanoparticle morphologies and surface properties of waterborne polyurethane controlled by water. AB - Water plays important roles in organic reactions such as polyurethane synthesis, and the aqueous solution environment affects polymer morphology and other properties. This paper focuses on the morphology and surface properties of waterborne polyurethane resulting from the organic reaction in water involving different forms (solid and liquid), temperatures and aqueous solutions. We provide evidence from TEM observations that the appearance of polyurethane nanoparticles in aqueous solutions presents diverse forms, including imperfect spheres, perfect spheres, perfect and homogenous spheres and tubes. Based on the results on FTIR, GPC, AFM and XRD experiments, we suggest that the shape of the nanoparticles may be decided by the crimp degree (i.e., the degree of polyurethane chains intertangling in the water environment) and order degree, which are determined by the molecular weight (Mn) and hydrogen bonds. Meanwhile, solid water and high-temperature water can both reduce hard segments that gather on the polyurethane film surface to reduce hydrophilic groups and produce a soft surface. Our findings show that water may play key roles in aqueous polymer formation and bring order to molecular chains.

PMID- 27687004 TI - Plasmablastic lymphoma phenotype is determined by genetic alterations in MYC and PRDM1. AB - Plasmablastic lymphoma is an uncommon aggressive non-Hodgkin B-cell lymphoma type defined as a high-grade large B-cell neoplasm with plasma cell phenotype. Genetic alterations in MYC have been found in a proportion (~60%) of plasmablastic lymphoma cases and lead to MYC-protein overexpression. Here, we performed a genetic and expression profile of 36 plasmablastic lymphoma cases and demonstrate that MYC overexpression is not restricted to MYC-translocated (46%) or MYC amplified cases (11%). Furthermore, we demonstrate that recurrent somatic mutations in PRDM1 are found in 50% of plasmablastic lymphoma cases (8 of 16 cases evaluated). These mutations target critical functional domains (PR motif, proline rich domain, acidic region, and DNA-binding Zn-finger domain) involved in the regulation of different targets such as MYC. Furthermore, these mutations are found frequently in association with MYC translocations (5 out of 9, 56% of cases with MYC translocations were PRDM1-mutated), but not restricted to those cases, and lead to expression of an impaired PRDM1/Blimp1alpha protein. Our data suggest that PRDM1 mutations in plasmablastic lymphoma do not impair terminal B-cell differentiation, but contribute to the oncogenicity of MYC, usually disregulated by MYC translocation or MYC amplification. In conclusion, aberrant coexpression of MYC and PRDM1/Blimp1alpha owing to genetic changes is responsible for the phenotype of plasmablastic lymphoma cases. PMID- 27687005 TI - Prognostic impact of MYC protein expression in central nervous system diffuse large B-cell lymphoma: comparison with MYC rearrangement and MYC mRNA expression. AB - The prognostic role of MYC has been well documented in non-central nervous system diffuse large B-cell lymphoma; however, it remains controversial in central nervous system diffuse large B-cell lymphoma. To investigate the prognostic value of MYC, we analyzed the MYC protein expression by immunohistochemistry, mRNA expression by RNA in situ hybridization, and gene status by fluorescence in situ hybridization in 74 cases of central nervous system diffuse large B-cell lymphoma. Moreover, we examined the correlation between MYC translocation, mRNA expression, and protein expression. The mean percentage of MYC immunopositive cells was 49%. Using a 44% cutoff value, 49 (66%) cases showed MYC protein overexpression. The result of mRNA in situ hybridization using the RNA scope technology was obtained using the H-scoring system; the median value was 34.2. Using the cutoff value of 63.5, 16 (22%) cases showed MYC mRNA overexpression. MYC gene rearrangement was detected in five out of 68 (7%) cases. MYC translocation showed no statistically significant correlation with mRNA expression; however, all MYC translocation-positive cases showed MYC protein overexpression, with a higher mean percentage of MYC protein expression than that of translocation-negative cases (78 vs 48%, P=0.001). The level of MYC mRNA expression was moderately correlated with the level of MYC protein expression (P<0.001). The mean percentage of MYC protein expression in the high MYC mRNA group was higher than that in the low MYC mRNA group (70 vs 47%, P<0.001). A univariate analysis showed that age over 60 years, Eastern Cooperative Oncology Group (ECOG) performance status >=2 and MYC protein overexpression were significantly associated with an increased risk of death. MYC translocation and MYC mRNA expression had no prognostic significance. On multivariate analysis, MYC protein overexpression and ECOG score retained prognostic significance.

The microdisks are integrated with side-coupling bus waveguides in a two-dimensional photonic circuit. The second harmonic generation is excited with a continuous wave laser in the telecom band. By fabricating a series of microdisks with diameters varying by steps of 8 nm, we obtain a tuning of the whispering gallery mode resonances for the fundamental and harmonic waves. Phase matching is obtained when both resonances are matched with modes satisfying the conservation of orbital momentum, which leads to a pronounced enhancement of frequency conversion. PMID- 27687008 TI - Can Nursing Units With High Fall Rates Be Identified Using One Year of Data? Reliability of Fall Rates As a Function of the Number of Quarters on Which They Are Based. AB - Reliability-the extent to which multiple measurements of a target yield similar results-is critical in comparing healthcare provider quality. Hospital unit fall rates are widely tracked and used for benchmarking, but their reliability is not well-studied. Our twofold purpose was to estimate fall rate reliability, both in terms of signal (between-unit variability) relative to noise (within-unit variability) and in terms of the accuracy with which units can be classified as high-fall units; and to assess reliability as a function of the number of quarters of data used to compute fall rates. Using year 2013 data from 11,765 critical care, step-down, medical, surgical, medical-surgical, and rehabilitation units in 1,552 US hospitals, we identified high-fall-rate units, computed units' signal-noise reliability, and simulated data to assess accuracy of high-fall-rate unit classification as a function of quarters of data. When critical care units were excluded, median unit type signal-noise reliabilities for annual total and injurious fall rates, respectively, ranged from .74 to .82 and from .53 to .68. In simulation, seven quarters of data were sufficient to achieve top-decile misclassification rates at or below 10% for all unit types except critical care. Top-quartile misclassification rates were higher; even 12 quarters of data did not consistently yield top-quartile misclassification rates below 10%. In the absence of long-term data, and for units with low patient volume and unit types with very low fall rates, comparison with a unit's own historical data may be more helpful for quality monitoring than attempting to rank it among its peers.

PMID- 27687006 TI - Fatty acid-binding protein 1 is preferentially lost in microsatellite instable colorectal carcinomas and is immune modulated via the interferon gamma pathway. AB - Fatty acid-binding protein 1 (FABP1) is an intracellular protein responsible for the transportation of long chain fatty acids. Aside from its functions in lipid metabolism and cellular differentiation, FABP1 also plays a role in inflammation through its interaction with peroxisome proliferator-activated receptors (PPARs). Previously, we compared expression of colonic epithelium genes in a subset of microsatellite instable (MSI) colorectal carcinomas (medullary carcinomas) to normal colonic mucosa and found that FABP1 expression was markedly decreased in the tumors. Further analysis of RNA expression in the colorectal subtypes and The Cancer Genome Atlas data set found that FABP1 expression is decreased in the CMS1 subset of colorectal carcinomas, which is characterized by microsatellite instability. As MSI colorectal carcinomas are known for their robust immune response, we then aimed to link FABP1 to the immune microenvironment of MSI carcinomas. To confirm the gene expression results, we performed immunohistochemical analysis of a cohort of colorectal carcinomas. FABP1 was preferentially lost in MSI carcinomas (123/133, 93%) compared with microsatellite stable carcinomas (240/562, 43%, P<0.0001). In addition, higher numbers of tumor infiltrating lymphocytes were present in tumors with loss of FABP1 (P<0.0001). Decreased expression of the fatty acid storage and glucose regulator, PPARgamma, was associated with the loss of FABP1 (P<0.0001). Colorectal cancer cell lines treated with interferon gamma exhibited decreased expression of FABP1. FABP1 expression was partially recovered with the treatment of the cell lines with rosiglitazone, a PPARgamma agonist. This study demonstrated that the loss of FABP1 expression is associated with MSI carcinomas and that interferon gamma stimulation plays a role in this process via its interaction with PPARgamma. PMID- 27687009 TI - A Green Approach to the Synthesis of alpha-Amino Phosphonate in Water Medium: Carbene Insertion into the N-H Bond by Cu(I) Catalyst. AB - Synthesis of amino phosphonates is more important owing to their significant applications in the biological systems. There are few methods already known in the literature to make these molecules; however, known methods have their own disadvantages. In this regard, synthesis of different kinds of amino phosphonates have been achieved via phosphonate substituted carbene insertion into the N-H bond of aniline catalyzed by readily available copper salt under mild reaction conditions in water. In order to find an efficient catalyst for carbene insertion reaction in neat water, a large number of transition metal catalysts were screened, and we found that the [Cu(CH3CN)4]ClO4 was the best catalyst under employed reaction conditions. Using this environmentally benign methodology (copper catalyzed reaction in water), a large number of biologically important amino phosphonates have been synthesized, isolated (37 examples), and characterized using standard analytical and spectroscopic techniques. PMID- 27687010 TI - Discrimination and internalised feelings experienced by people who stutter in Jordan. AB - PURPOSE: This study investigated the internalised feelings and discrimination experienced by people who stutter in Jordan. METHOD: Five adult speakers who stutter were interviewed as a focus group. The participants were asked about their feelings related to stuttering and discrimination. The participants' responses in the focus group and items adapted from the extant literature formed the basis of a 20-item questionnaire. The questionnaire was administered to 20 additional adults who stutter to assess their internalised feelings about stuttering and their perceived rejecting behaviours (discrimination) associated with their impairment. RESULT: Feeling "annoyed" was the item that received the highest percentage of negative internalised feelings, followed by "embarrassed," "shame," "disappointed," "nervous, "sad," "pessimistic," "fearful," "worried" and "lonely." The results of the discrimination experiences indicated that "getting a leadership position" was the item that most people who stutter reported being worried about, followed by "participation in the classroom," "getting a job," "getting married," "being fully paid in their jobs," "teased," "promoted" and "renting a house." CONCLUSION: These findings provide further evidence of the universality that stuttering is more than the core surface features of speech, but also include aspects that exist below the surface such as negative internalised feelings and various discrimination experiences. PMID- 27687011 TI - Superficial malignant peripheral nerve sheath tumor with overlying intradermal melanocytic nevus mimicking spindle cell melanoma. AB - Malignant peripheral nerve sheath tumors are rare soft tissue sarcomas with histological and immunohistochemical similarities to spindle cell melanoma. Although spindle cell melanoma is significantly more common, both tumors may express S100 and lack staining for HMB-45, Melan-A or MITF. Here we present a case of superficial malignant peripheral nerve sheath tumor with diffuse S100 positivity arising in a subtle neurofibroma in close proximity to an intradermal melanocytic nevus. This configuration had led to prior misdiagnosis as a desmoplastic melanoma arising in the nevus and to sentinel lymph node biopsy. Identification of the background neurofibroma, as well as CD34 positivity raised consideration of a low grade malignant peripheral nerve sheath tumor, which was confirmed via observation of Schwannian differentiation on electron microscopy. The importance of distinguishing these two tumors is stressed owing to the difference in management. PMID- 27687012 TI - Impact of chromium dinicocysteinate supplementation on inflammation, oxidative stress, and insulin resistance in type 2 diabetic subjects: an exploratory analysis of a randomized, double-blind, placebo-controlled study. AB - BACKGROUND: Chromium dinicocysteinate (CDNC) is a unique chromium complex consisting of chromium, niacin, and L-cysteine. Previous preclinical and clinical studies support the safety and efficacy of CDNC in modulating oxidative stress, vascular inflammation, and glycemia in type 2 diabetes. OBJECTIVE: Herein, we report the results of several exploratory analyses conducted on type 2 diabetic subjects who previously participated in a 3-month randomized, double-blind, placebo-controlled trial and were treated with only metformin as standard diabetic care in addition to receiving the test supplementations. DESIGN: Results from 43 metformin users, who were randomly assigned to receive either placebo (P, n=13), chromium picolinate (CP, 400 ug elemental Cr(3+)/day, n=12), or CDNC (400 ug elemental Cr(3+)/day, n=18), were analyzed for blood markers of vascular inflammation, insulin resistance, and oxidative stress at baseline and at 3 months of supplementation. RESULTS: A statistically significant decrease in insulin resistance in the CDNC-supplemented cohort compared to placebo (p=0.01) was observed at 3 months. The CDNC group also demonstrated a significant reduction in insulin levels (p=0.03), protein carbonyl (p=0.02), and in TNF-alpha (p=0.03) compared to the placebo group. The CP group only showed a significant reduction in protein carbonyl levels (p=0.03) versus placebo. CONCLUSIONS: When controlling for diabetes medication, CDNC supplementation showed beneficial effects on blood markers of vascular inflammation, insulin resistance, and oxidative stress compared to placebo. The findings suggest that CDNC supplementation has potential as an adjunct therapy for individuals with type 2 diabetes. PMID- 27687013 TI - Becoming Therapeutic Agents: A Grounded Theory of Mothers' Process When Implementing Cognitive Behavioural Therapy at Home with an Anxious Child. AB - : The premise of parent-centred programmes for parents of anxious children is to educate and train caregivers in the sustainable implementation of cognitive behaviour therapy (CBT) in the home. The existing operationalization of parent involvement, however, does not address the systemic, parent or child factors that could influence this process. The qualitative approach of grounded theory was employed to examine patterns of action and interaction involved in the complex process of carrying out CBT with one's child in one's home. A grounded theory goes beyond the description of a process, offering an explanatory theory that brings taken-for-granted meanings and processes to the surface. The theory that emerged from the analysis suggests that CBT implementation by mothers of anxious children is characterized by the evolution of mothers' perception of their child and mothers' perception of their role as well as a shift from reacting with emotion to responding pragmatically to the child. Changes occur as mothers recognize the crisis, make links between the treatment rationale, child's symptoms and their own parenting strategies, integrate tenets of CBT for anxiety and eventually focus on sustaining therapeutic gains through natural life transitions. The theory widens our understanding of mothers' role, therapeutic engagement, process, and decision-making. The theory also generates new hypotheses regarding parent involvement in the treatment of paediatric anxiety disorders and proposes novel research avenues that aim to maximize the benefits of parental involvement in the treatment of paediatric anxiety disorders. Copyright (c) 2016 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Mothers of anxious youth who take part in parent-centred programmes experience a shift in their perception of the child and of their role. Parental strategy after CBT implementation shifts from emotional empathy to cognitive empathy. Mothers experience significant challenges and require additional support in prevention of relapse and knowledge translation. PMID- 27687014 TI - Can pictures promote the acquisition of sight-word reading? An evaluation of two potential instructional strategies. AB - Sight-word instruction can be a useful supplement to phonics-based methods under some circumstances. Nonetheless, few studies have evaluated the conditions under which pictures may be used successfully to teach sight-word reading. In this study, we extended prior research by examining two potential strategies for reducing the effects of overshadowing when using picture prompts. Five children with developmental disabilities and two typically developing children participated. In the first experiment, the therapist embedded sight words within pictures but gradually faded in the pictures as needed using a least-to-most prompting hierarchy. In the second experiment, the therapist embedded text-to picture matching within the sight-word reading sessions. Results suggested that these strategies reduced the interference typically observed with picture prompts and enhanced performance during teaching sessions for the majority of participants. Text-to-picture matching also accelerated mastery of the sight words relative to a condition under which the therapist presented text without pictures.

AB - Till now, no evidence illustrates the prevalence and predictors of metabolically healthy obesity (MHO) in rural areas of China. The objective of this study was, firstly, to examine the prevalence of MHO in rural areas of China, and identify contributing determinants of MHO, Secondly, to comprehensively investigate to the different characteristics between MHO and metabolically unhealthy obesity (MUO). We conducted a population-based cross-sectional study of 2037 participants with obesity in rural Liaoning Province during 2012-2013. Obesity was defined as BMI >=28 kg/m2 and metabolically healthy was defined as not having the metabolic syndrome. The prevalence of MHO was 23.1%, and significantly decreased with advancing age in female group. However there was no significant tendency with advancing age in male group. Independent determinant factors for MHO were age <55 years (odds ratio [OR] 1.659; p = .001), non-current smoking (OR 1.397; p = .038), pre-menopause (OR 1.648; p = .030) and non-hyperuricemia (OR 2.317; p < .001), whereas race, gender, diet score, current drinking, marriage, sleep duration, hyperhomocysteinemia, levels of physical activity, annual income and educational status were not significant contributors. In conclusion, we found that age <55 years, non-current smoking, pre-menopause and non-hyperuricemia were identified as independent determinant factors for MHO in this population. PMID- 27687017 TI - Short and long time MR signal behavior of randomly distributed water and fat numerical simulations. AB - The MR time-signal behavior of water has been reported to be different on short and long time scales for systems of randomly distributed perturbers in water in the static dephasing regime. Up to now, the signal of the perturbers in such systems has not been taken into consideration. Water-fat emulsions are macroscopically homogeneous systems and can be considered as microscopically randomly distributed perturbing fat spheres embedded in water. In such water-fat systems, the signal of the perturber, fat, cannot be ignored. Since water and fat are within the same system, the fat signal behavior may show similarities with water, with differences in short and long time scales. This could complicate fat referenced MR thermometry (MRT) methods such as multi-gradient echo-based (MGE) MRT. Simulations were performed using a numerical phantom comprising spherical fat objects embedded in a spherical water medium. To characterize the fat signal, the theoretical signal description of water was fitted to the simulated fat signal. The simulated signals were sampled as an MGE signal and MGE MRT was used to calculate temperatures. The sampling was done with and without delay, to investigate the effect on the temperature error of the time ranges in which the signal was sampled. It was confirmed that the fat signal behavior was similar to that of water and consisted of two regimes. The separation between the short and long time scales was approximately at 55 ms for fat, as compared with 8.9 ms for water. Without delayed signal sampling, the MGE MRT temperature error was about 2.5 degrees C. With delayed sampling such that both the water and the fat signals were either in the short or in the long time scale the error was reduced to 0.2 degrees C. PMID- 27687018 TI - The future of Australia's Indigenous Population, 2011-61. AB - Existing projections of Australia's Indigenous Population suffer from a number of limitations: problematic input data, unsatisfactory projection model design, and poor forecast performance. The aim of this study was to create a new model for projecting that population that better represents the demographic processes at work, and that makes use of a newly available data source on identification change. A new projection model is presented that explicitly incorporates ethnic identification change, and mixed (Indigenous/Non-Indigenous) partnering and childbearing. It is a composite static-dynamic model which takes a multi-state form where data allow. The model was used to produce projections for the 2011-61 period. Rapid growth of the Indigenous Population is expected, with population momentum, identification change, and mixed partnering and childbearing shown to contribute more to growth than above-replacement fertility and increasing life expectancy. The future growth of Australia's Indigenous Population is thus intimately connected to its interaction with the Non-Indigenous Population.

AB - Although Internet games have been proven to be addictive, only a few game players develop online gaming addiction. A large number of players play online games recreationally without being addicted to it. These individuals are defined as recreational Internet gaming users (RGU). So far, no research has investigated decision-making and impulse control in RGU. In the current study, we used delay discounting (DD) task and probabilistic discounting (PD) task to examine decision making and impulse control in 20 healthy controls, 20 subjects with Internet gaming disorder (IGD) and 23 RGU during fMRI scanning. At the behavioral level, RGU showed lower DD rate and higher PD rate than subjects with IGD and there was no significant difference between RGU and healthy controls on the DD and PD rates. At the neural level, RGU showed increased neural response in the parahippocampal gyrus, the anterior cingulate cortex, the medial frontal gyrus and the inferior frontal gyrus as compared with subjects with IGD. These brain regions may play an important role in preventing RGU from developing addiction. The results suggest that the RGU are capable of inhibiting impulse due to additional cognitive endeavor and the subjects with IGD have deficit in decision making and impulsive control, which are associated with brain dysfunction.

AB - Systemic lupus erythematosus (SLE), a disorder of the immune system, is potentially curable by allogeneic bone marrow transplantation (alloBMT). Until recently, alloBMT was limited by donor availability and toxicity. Reduced intensity conditioning (RIC) combined with post-transplantation cyclophosphamide (PTCy) has improved the availability and safety of alloBMT permitting its exploration in severe-refractory autoimmune illnesses. We report the six-year follow-up of a young female whose refractory SLE-associated nephrosis resolved after RIC alloBMT with PTCy. PMID- 27687022 TI - The prevalence of self-reported lower limb and foot health problems experienced by participants with systemic lupus erythematosus: Results of a UK national survey. AB - Objective The main aim of this survey was to determine the frequency of self reported lower limb or foot and ankle complications experienced by participants with systemic lupus erythematosus (SLE). A secondary aim was to determine the frequency of treatments that have been received or that participants with SLE may like to receive if offered. Method A quantitative, cross-sectional, self-reported survey design was utilized. The developed survey was checked for face and content validity prior to patient partner cognitive debriefing in order to ensure usability, understanding of the process of completion and of the questions posed. The full protocol for survey development has been published previously. Results This is the first comprehensive national UK survey of lower limb and foot health problems reported by participants with SLE. A high prevalence of vascular, dermatological and musculoskeletal complications was reported by survey respondents. Additionally, whilst the relative prevalence of sensory loss was low, a quarter of people reported having had a fall related to changes in foot sensation demonstrating a previously unknown rate and cause of falls. Conclusion Complications related to vascular, dermatological and musculoskeletal health are identified as particularly prevalent in participants with SLE. Further, there is a suggestion that the provision of interventions to maintain lower limb health is highly varied and lacks national standardization, despite there being a strong indication of participant reported need. The findings of this work can be used to inform care guideline development in addition to identifying areas for future research. PMID- 27687023 TI - Biological therapies in the treatment of cutaneous lupus erythematosus. AB - Cutaneous lupus erythematosus (CLE) is an autoimmune skin disease occurring in association with or without systemic lupus erythematosus (SLE). Although antimalarials are widely used as the first-line systemic agent, refractory cases may benefit from additional immunomodulators, immunosuppressives, and biologics. An interest in biological therapies for CLE has emerged in recent years due to novel insight into the pathogenesis of CLE. These targets include B cells, T cells, and cytokines that are involved in immune system pathways. Currently belimumab is the only biological therapy approved for SLE and no biologic has been approved for CLE. While there is a paucity of high quality evidence with regard to biologics in CLE management, trials are currently being performed to determine their role. PMID- 27687024 TI - Complementary role of cardiovascular imaging and laboratory indices in early detection of cardiovascular disease in systemic lupus erythematosus. AB - Background Cardiovascular disease (CVD) has been documented in >50% of systemic lupus erythematosus (SLE) patients, due to a complex interplay between traditional risk factors and SLE-related factors. Various processes, such as coronary artery disease, myocarditis, dilated cardiomyopathy, vasculitis, valvular heart disease, pulmonary hypertension and heart failure, account for CVD complications in SLE. Methods Electrocardiogram (ECG), echocardiography (echo), nuclear techniques, cardiac computed tomography (CT), cardiovascular magnetic resonance (CMR) and cardiac catheterization (CCa) can detect CVD in SLE at an early stage. ECG and echo are the cornerstones of CVD evaluation in SLE. The routine use of cardiac CT and nuclear techniques is limited by radiation exposure and use of iodinated contrast agents. Additionally, nuclear techniques are also limited by low spatial resolution that does not allow detection of sub endocardial and sub-epicardial lesions. CCa gives definitive information about coronary artery anatomy and pulmonary artery pressure and offers the possibility of interventional therapy. However, it carries the risk of invasive instrumentation. Recently, CMR was proved of great value in the evaluation of cardiac function and the detection of myocardial inflammation, stress-rest perfusion defects and fibrosis. Results An algorithm for CVD evaluation in SLE includes clinical, laboratory, ECG and echo assessment as well as CMR evaluation in patients with inconclusive findings, persistent cardiac symptoms despite normal standard evaluation, new onset of life-threatening arrhythmia/heart failure and/or as a tool to select SLE patients for CCa. Conclusions A non invasive approach including clinical, laboratory and imaging evaluation is key for early CVD detection in SLE. PMID- 27687025 TI - 25-hydroxyvitamin D is associated with metabolic syndrome among premenopausal women with systemic lupus erythematosus in China. AB - Objectives This study aimed to investigate the status of 25-hydroxyvitamin D (25(OH)D) and its association with metabolic syndrome (MS) and different MS components among premenopausal women with systemic lupus erythematosus (SLE) in China. Patients and methods Altogether 113 premenopausal women with SLE and the age-matched healthy cohorts were recruited in this cross-sectional study. Clinical manifestations and laboratory data including serum 25(OH)D concentration were collected. A multivariable analysis was performed to analyze the association of 25(OH)D with MS and its components. Results The prevalence of 25(OH)D deficiency (25(OH)D < 20 ng/ml) and MS were common (24.8% and 30.1%, respectively) in premenopausal patients with SLE in China. Analysis of the association between 25(OH)D, MS and its components demonstrated that the lower level of 25(OH)D was associated with increased MS prevalence (OR = 0.920, p = 0.012), a decreased level of high-density lipoprotein (OR = 1.059, p = 0.033) and a higher level of fasting glucose (OR = 0.810, p = 0.004). These associations were still detectible after adjustment for age, body mass index and SLE-related variables. Conclusion The level of 25(OH)D is associated with MS and its components in premenopausal women with SLE. PMID- 27687026 TI - Fatigue and cognitive function in systemic lupus erythematosus: associations with white matter microstructural damage. A diffusion tensor MRI study and meta analysis. AB - Objective The objective of this study was to investigate fatigue and cognitive impairments in systemic lupus erythematous (SLE) in relation to diffuse white matter microstructural brain damage. Methods Diffusion tensor MRI, used to generate biomarkers of brain white matter microstructural integrity, was obtained in patients with SLE and age-matched controls. Fatigue and cognitive function were assessed and related to SLE activity, clinical data and plasma biomarkers of inflammation and endothelial dysfunction. Results Fifty-one patients with SLE (mean age 48.8 +/- 14.3 years) were included. Mean diffusivity (MD) was significantly higher in all white matter fibre tracts in SLE patients versus age matched healthy controls ( p < 0.0001). Fatigue in SLE was higher than a normal reference range ( p < 0.0001) and associated with lower MD ( beta = -0.61, p = 0.02), depression ( beta = 0.17, p = 0.001), anxiety ( beta = 0.13, p = 0.006) and higher body mass index ( beta = 0.10, p = 0.004) in adjusted analyses. Poorer cognitive function was associated with longer SLE disease duration ( p = 0.003) and higher MD ( p = 0.03) and, in adjusted analysis, higher levels of IL-6 ( beta = -0.15, p = 0.02) but not with MD. Meta-analysis (10 studies, n = 261, including the present study) confirmed that patients with SLE have higher MD than controls. Conclusion Patients with SLE have more microstructural brain white matter damage for age than the general population, but this does not explain increased fatigue or lower cognition in SLE. The association between raised IL-6 and worse current cognitive function in SLE should be explored in larger datasets. PMID- 27687027 TI - Lupus nephritis is associated with more corticosteroid-associated organ damage but less corticosteroid non-associated organ damage. AB - Objective The objective of this study was to investigate the association of lupus nephritis on organ damage and mortality in patients with systemic lupus erythematosus (SLE). Methods A total of 1112 patients with SLE were investigated. Lupus nephritis was defined as a proteinuria based on the 1997 American College of Rheumatology criteria. Damage was assessed using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index. The associations of lupus nephritis with overall, non-renal, corticosteroid-associated, and non-associated damage were analyzed using logistic regression. The age-adjusted and sex-adjusted standardized mortality ratio was evaluated in patients with and without lupus nephritis. Results The prevalence of lupus nephritis in patients with SLE was 46.3%. Patients with lupus nephritis had a higher percentage of overall cumulative damage than patients without lupus nephritis (51.5% vs. 35.7%, p < 0.001). The odds ratio was 1.40 after adjusting for age at SLE diagnosis, sex, disease duration, anti-malarial agents, immunosuppressive agents and cumulative corticosteroid dose. Among non-renal damage, the odds of corticosteroid-associated damage were higher (2.06, 95% confidence interval (CI) 1.43-2.96) whereas the odds of non-associated damage were lower (0.50, 95% CI 0.35-0.75) in patients with lupus nephritis. The standardized mortality ratios of patients with and without lupus nephritis were 5.17 (95% CI 3.49-7.38) and 2.32 (95% CI 1.47-3.48), respectively. Conclusion In patients with SLE, the presence of lupus nephritis is associated with increased corticosteroid-associated damage but less corticosteroid non-associated damage. Also, mortality is significantly higher in patients with lupus nephritis than in those without lupus nephritis.

AB - Objective There is a decreased breast cancer risk in systemic lupus erythematosus (SLE) versus the general population. We assessed a large sample of SLE patients, evaluating demographic and clinical characteristics and breast cancer risk. Methods We performed case-cohort analyses within a multi-center international SLE sample. We calculated the breast cancer hazard ratio (HR) in female SLE patients, relative to demographics, reproductive history, family history of breast cancer, and time-dependent measures of anti-dsDNA positivity, cumulative disease activity, and drugs, adjusted for SLE duration. Results There were 86 SLE breast cancers and 4498 female SLE cancer-free controls. Patients were followed on average for 7.6 years. Versus controls, SLE breast cancer cases tended to be white and older. Breast cancer cases were similar to controls regarding anti dsDNA positivity, disease activity, and most drug exposures over time. In univariate and multivariate models, the principal factor associated with breast cancers was older age at cohort entry. Conclusions There was little evidence that breast cancer risk in this SLE sample was strongly driven by any of the clinical factors that we studied. Further search for factors that determine the lower risk of breast cancer in SLE may be warranted. PMID- 27687029 TI - Urinary sediment suggests lupus nephritis histology. AB - Objectives The objective of this paper was to evaluate correlations between kidney biopsy indexes (activity and chronicity) and urinary sediment findings; the secondary objective was to find which components of urinary sediment can discriminate proliferative from other classes of lupus nephritis. Methods Lupus nephritis patients scheduled for a kidney biopsy were included in our study. The morning before the kidney biopsy, we took urine samples from each patient. Receiver operating characteristic (ROC) curves were plotted to determine the area under the curve (AUC) of each test for detecting proliferative lupus nephritis; a classification tree was calculated to select a set of values that best-predicted lupus nephritis classes. Results We included 51 patients, 36 of whom were women (70.6%). Correlations of lupus nephritis activity index with the counts in the urinary sediment of erythrocytes (isomorphic and dysmorphic), acanthocytes, and leukocytes were 0.65 ( p < 0.0001) 0.62 ( p < 0.0001) and 0.22 ( p = 0.1228), respectively. Correlations of lupus nephritis chronicity index with the counts of erythrocytes, acanthocytes, and leukocytes were 0.60 ( p <= 0.0001), 0.52 ( p = 0.0001) and 0.17 ( p = 0.2300), respectively. Our classification tree had an accuracy of 84.3%. Conclusions Evaluation of urine sediment reflects lupus nephritis histology. PMID- 27687033 TI - Russia's generalising HIV epidemic. PMID- 27687032 TI - Impact of bromocriptine-QR therapy on cardiovascular outcomes in type 2 diabetes mellitus subjects on metformin. AB - OBJECTIVES: Type 2 diabetes mellitus (T2DM) is associated with a substantially increased risk of cardiovascular disease (CVD). Bromocriptine-QR (B-QR), a quick release sympatholytic dopamine D2 receptor agonist, is a FDA-approved therapy for T2DM which may provide CVD risk reduction. Metformin is considered to be an agent with a potential cardioprotective benefit. This large placebo controlled clinical study assessed the impact of B-QR addition to existing metformin therapy on CVD outcomes in T2DM subjects. METHODS: 1791 subjects (1208 B-QR; 583 placebo) on metformin +/- another anti-diabetes therapy at baseline derived from the Cycloset Safety Trial, a 12-month, randomized, multicenter, placebo-controlled, double blind study in T2DM, were included in this study. The primary CVD endpoint evaluated was treatment impact on CVD event rate, prespecified as a composite of time to first myocardial infarction, stroke, coronary revascularization, or hospitalization for unstable angina/congestive heart failure. Impact on glycemic control was evaluated as a secondary analysis. RESULTS: The composite CVD end point occurred in 16/1208 B-QR treated (1.3%) and 18/583 placebo treated (3.1%) subjects resulting in a 55% CVD hazard risk reduction (intention-to-treat, Cox regression analysis; HR: 0.45 [0.23-0.88], p = 0.028). Kaplan-Meier curves demonstrated a significantly lower cumulative incidence rate of the CVD endpoint in the B-QR treatment group (Log-Rank p = 0.017). In subjects with poor glycemic control (HbA1c >= 7.5) at baseline, B-QR therapy relative to placebo resulted in a significant mean %HbA1c reduction of -0.59 at week 12 and -0.51 at week 52 respectively (p < 0.001 for both) and a 10 fold higher percent of subjects achieving HbA1c goal of <=7% by week 52 (B-QR 30%, placebo 3%; p = 0.003). CONCLUSION: These findings suggest that in T2DM subjects on metformin, BQR therapy may represent an effective strategy for reducing CVD risk.

PMID- 27687031 TI - Transgenic expression of phytase in wheat endosperm increases bioavailability of iron and zinc in grains. AB - Phytate is a major constituent of wheat seeds and chelates metal ions, thus reducing their bioavailability and so the nutritional value of grains. Transgenic plants expressing heterologous phytase are expected to enhance degradation of phytic acid stored in seeds and are proposed to increase the in vitro bioavailability of mineral nutrients. Wheat transgenic plants expressing Aspergillus japonicus phytase gene (phyA) in wheat endosperm were developed till T3 generation. The transgenic lines exhibited 18-99 % increase in phytase activity and 12-76 % reduction of phytic acid content in seeds. The minimum phytic acid content was observed in chapatti (Asian bread) as compared to flour and dough. The transcript profiling of phyA mRNA indicated twofold to ninefold higher expression as compared to non transgenic controls. There was no significant difference in grain nutrient composition of transgenic and non transgenic seeds. In vitro bioavailability assay for iron and zinc in dough and chapatti of transgenic lines revealed a significant increase in iron and zinc contents. The development of nutritionally enhanced cereals is a step forward to combat nutrition deficiency for iron and zinc in malnourished human population, especially women and children.

PMID- 27687041 TI - Temporal Regularity Detection and Rate Discrimination in Cochlear-Implant Listeners. AB - Cochlear implants (CIs) convey fundamental-frequency information using primarily temporal cues. However, temporal pitch perception in CI users is weak and, when measured using rate discrimination tasks, deteriorates markedly as the rate increases beyond 300 pulses-per-second. Rate pitch may be weak because the electrical stimulation of the surviving neural population of the implant recipient may not allow accurate coding of inter-pulse time intervals. If so, this phenomenon should prevent listeners from detecting when a pulse train is physically temporally jittered. Performance in a jitter detection task was compared to that in a rate-pitch discrimination task. Stimuli were delivered using direct stimulation in cochlear implants, on a mid-array and an apical electrode, and at two different rates (100 and 300 pps). Average performance on both tasks was worse at the higher pulse rate and did not depend on electrode. However, there was a large variability across and within listeners that did not correlate between the two tasks, suggesting that rate-pitch judgement and regularity detection are to some extent limited by task-specific processes. Simulations with filtered pulse trains presented to NH listeners yielded broadly similar results, except that, for the rate discrimination task, the difference between performance with 100- and 300-pps base rates was smaller than observed for CI users. PMID- 27687042 TI - Simvastatin enhances the hippocampal klotho in a rat model of streptozotocin induced cognitive decline. AB - Brain oxidative status is a crucial factor in the development of sporadic Alzheimer's disease (AD). Klotho, an anti-aging protein, diminishes oxidative stress by the induction of manganese superoxide dismutase (MnSOD). Thus, the substances that increase klotho expression could be considered as a potential treatment for Alzheimer's disease when the oxidative imbalance is present. Statins are suggested to up-regulate klotho expression. We examined the effect of simvastatin (5mg/kg, daily for 3weeks) on hippocampal klotho and MnSOD expression in the cognitive declined animal model induced by intracerebroventricular (ICV) streptozotocin (STZ) administration. Cognitive assessment was performed by the Morris Water Maze (MWM) test. The results indicated that mean escape latency and distance were prolonged in the ICV-STZ group compared with the control group. The expression of klotho and MnSOD were also down regulated in the hippocampus. Furthermore, improved spatial performance was observed in simvastatin-treated animals. This effect could be related to increase in oxidative stress tolerance as evidenced by klotho and MnSOD up-regulation. Our current study indicates that klotho upregulation may be a neuroprotective mechanism of simvastatin against cognitive decline in AD. PMID- 27687043 TI - Different association between specific manifestations of bruxism and temporomandibular disorder pain. AB - INTRODUCTION: A growing body of evidence suggests that bruxism exists in two separate manifestations. However, little is known about the association between specific manifestations of bruxism and temporomandibular disorder (TMD) pain. AIM: The aim of our study was to analyze the association between TMD pain and specific diagnoses of bruxism (sleep, awake, and mixed diagnosis of sleep and awake bruxism). MATERIAL AND METHODS: 508 adult patients (296 women and 212 men), aged between 18 and 64 years (mean age 34+/-12 years), attending to a clinic for general dental treatment. Patients were asked to fill an anonymous questionnaire, consisting of three questions, verifying the presence of TMD pain and two forms of bruxism. All questions were based on the Polish version of the Research Diagnostic Criteria for Temporomandibular Disorders patient history questionnaire. Cross tabulation was done, and chi2 was used as a test of significance to find the association between the variables. RESULTS: Awake bruxism was associated with TMD pain only in men (chi2=7.746, p<0.05) while mixed diagnosis of bruxism was associated with TMD pain in both women (chi2=10.486, p<0.05) and men (chi2=4.314, p<0.05). There was no statistically significant association between sleep bruxism and TMD pain. Gender-related differences in the presence of all bruxism diagnoses were also statistically insignificant. CONCLUSIONS: Interaction between sleep and awake bruxism may increase the risk for TMD pain. We suggest considering concomitance as a confounder, when studying sleep or awake bruxism.

PMID- 27687044 TI - Feasibility and outcomes of interventional treatment for vascular access site complications following transfemoral aortic valve implantation. AB - BACKGROUND: Despite the completion of more than 60,000 transcutaneous aortic valve implantations (TAVI) per year and an approximately 10-15 % incidence of vascular access site complications (VAC), there is a paucity of data on the efficacy and safety of percutaneous VAC treatment. HYPOTHESIS: Percutaneous endovascular treatment will be an effective treatment of VAC and associated with a low rate of surgical repair. Despite stent placement in proximity to the hip joint, endovascular treatment will be only rarely associated with disabling symptoms or complications. METHODS: We conducted a retrospective database analysis including 355 patients who underwent TAVI from January 2011 to October 2015. To facilitate the detection of secondary complications of interventional VAC repair, we conducted structured telephone interviews with a focus on new diagnoses or symptoms of peripheral artery disease. RESULTS: Only four patients (1.1 %) required surgical treatment for VAC. Percutaneous balloon angioplasty (PTA) or stent implantation was required for VAC in 44 patients (12.4 %). The technical success rate of percutaneous VAC treatment was 93 %. Four patients died within 30 days of VAC treatment, but only one fatality was directly attributable to VAC. Post procedure mean hospital stay was numerically prolonged by 2.4 days in the VAC treatment group (P = 0.06). During a median follow-up of 385 days (range 89-909 days) none of the patients were diagnosed with a late VAC or reported a new diagnosis or symptoms of perfusion deficit or peripheral artery disease. CONCLUSION: Percutaneous treatment of VAC during TAVI is safe and effectively helps to minimize the need for surgery in the vast majority of VAC. During short- and mid-term follow-up, percutaneous VAC management is associated with low complication rates and good clinical outcomes.

PMID- 27687047 TI - Incidence of infusion reactions to anti-neoplastic agents in early phase clinical trials: The MD Anderson Cancer Center experience. AB - Infusion reactions (IRs) to anti-neoplastic agents require prompt recognition and immediate treatment to avert significant complications. We conducted a retrospective review of the medical records of consecutive patients who received anti-neoplastic therapy in the outpatient treatment center of the Department of Investigational Cancer Therapeutics from January 1, 2013 to November 30, 2013. Of the 597 patients who received treatment, 9 (1.5 %) had IRs (all <= grade 2). The most common IRs observed on first occurrence were chills (n = 5), itching, rash, and facial flushing (n = 3 each). There were no IR-related deaths. All the IRs were reversible with appropriate symptomatic treatment and the therapy was completed after temporary cessation of infusion in 7 of the 9 patients. The infusion was stopped in 2 patients due to symptoms suggestive of IgE-mediated allergic reaction and cytokine storm. Five of the 8 patients who were re challenged with the same therapy developed a similar reaction. However, the infusion was completed in 4 of the 5 patients after administration of intravenous diphenhydramine and/or hydrocortisone, or slowing the rate of infusion. And, subsequent cycles with the same agents were uneventful. IRs to anti-neoplastic agents are rare. Though the clinical presentations are overlapping, most IRs are not IgE-mediated allergic reactions. Appropriate premedication and slow rate of infusion facilitates uneventful administration of the anti-neoplastic agents in subsequent cycles. Further study in a larger cohort of patients to identify biomarkers of hypersensitivity is warranted. PMID- 27687049 TI - Cardiology consultation reduces provocative testing rates in an ED observation unit. AB - BACKGROUND: In evaluating patients with chest pain, emergency department observation units (EDOUs) may use a staffing model in which emergency physicians determine patient testing (EP model) or a model similar to a chest pain unit (CPU) in which cardiologists determine provocative testing (CPU model). METHODS: We performed a prospective study with 30-day telephone follow-up for all chest pain patients placed in our EDOU. Halfway through the study period, our EDOU transitioned from an EP model to a CPU model. We compared provocative testing rates and outcomes between the 2 models. RESULTS: Over the 34-month study period, our EDOU evaluated 1190 patients for chest pain. Patients placed in the EDOU during the 17-month CPU model were more likely to be moderate risk (Thrombolysis in Myocardial Infarction score 3-5) than those during the 17-month EP model: 24.9% vs 18.8%, P = .011. Despite this difference, rates of provocative testing (stress testing or coronary computed tomography) were lower during the CPU model: 47.1% vs 56.5%, P = .001. This reduction was particularly evident among low-risk patients (Thrombolysis in Myocardial Infarction score 0-2): 49.8% vs 58.1%, P = .011. Rates of myocardial infarction, percutaneous coronary intervention, or coronary artery bypass graft were similar between the 2 groups (2.8% vs 3.2%, P = .140). We noted no significant events or missed diagnoses in either group during the 30-day follow-up. CONCLUSION: An EDOU model that used mandatory cardiology consultation resulted in decreased provocative testing, particularly among low risk chest pain patients. Future research should explore the cost-effectiveness of this model. PMID- 27687050 TI - A dedicated palliative care nurse improves access to palliative care and hospice services in an urban ED. PMID- 27687052 TI - Meta-Analysis Comparing Established Risk Prediction Models (EuroSCORE II, STS Score, and ACEF Score) for Perioperative Mortality During Cardiac Surgery. AB - A wide variety of multivariable risk models have been developed to predict mortality in the setting of cardiac surgery; however, the relative utility of these models is unknown. This study investigated the literature related to comparisons made between established risk prediction models for perioperative mortality used in the setting of cardiac surgery. A systematic review was conducted to capture studies in cardiac surgery comparing the relative performance of at least 2 prediction models cited in recent guidelines (European System for Cardiac Operative Risk Evaluation [EuroSCORE II], Society for Thoracic Surgeons 2008 Cardiac Surgery Risk Models [STS] score, and Age, Creatinine, Ejection Fraction [ACEF] score) for the outcomes of 1-month or inhospital mortality. For articles that met inclusion criteria, we extracted information on study design, predictive performance of risk models, and potential for bias. Meta analyses were conducted to calculate a summary estimate of the difference in AUCs between models. We identified 22 eligible studies that contained 33 comparisons among the above models. Meta-analysis of differences in AUCs revealed that the EuroSCORE II and STS score performed similarly (with a summary difference in AUC = 0.00), while outperforming the ACEF score (with summary differences in AUC of 0.10 and 0.08, respectively, p <0.05). Other metrics of discrimination and calibration were presented less consistently, and no study presented any metric of reclassification. Small sample size and absent descriptions of missing data were common in these studies. In conclusion, the EuroSCORE II and STS score outperform the ACEF score on discrimination. PMID- 27687051 TI - Effect of Body Mass Index on Left Ventricular Mass in Career Male Firefighters. AB - Left ventricular (LV) mass is a strong predictor of cardiovascular disease (CVD) events; increased LV mass is common among US firefighters and plays a major role in firefighter sudden cardiac death. We aim to identify significant predictors of LV mass among firefighters. Cross-sectional study of 400 career male firefighters selected by an enriched randomization strategy. Weighted analyses were performed based on the total number of risk factors per subject with inverse probability weighting. LV mass was assessed by echocardiography (ECHO) and cardiac magnetic resonance, and normalized (indexed) for height. CVD risk parameters included vital signs at rest, body mass index (BMI)-defined obesity, obstructive sleep apnea risk, low cardiorespiratory fitness, and physical activity. Linear regression models were performed. In multivariate analyses, BMI was the only consistent significant independent predictor of LV mass indexes (all, p <0.001). A 1-unit decrease in BMI was associated with 1-unit (g/m1.7) reduction of LV mass/height1.7 after adjustment for age, obstructive sleep apnea risk, and cardiorespiratory fitness. In conclusion, after height-indexing ECHO-measured and cardiac magnetic resonance-measured LV mass, BMI was found to be a major driver of LV mass among firefighters. Our findings taken together with previous research suggest that reducing obesity will improve CVD risk profiles and decrease on-duty CVD and sudden cardiac death events in the fire service. Our results may also support targeted noninvasive screening for LV hypertrophy with ECHO among obese firefighters. PMID- 27687053 TI - DNA methyltransferases exhibit dynamic expression during spermatogenesis. AB - DNA methylation is one of the epigenetic marks and plays critically important functions during spermatogenesis in mammals. DNA methylation is catalysed by DNA methyltransferase (DNMT) enzymes, which are responsible for the addition of a methyl group to the fifth carbon atom of the cytosine residues within cytosine phosphate-guanine (CpG) and non-CpG dinucleotide sites. Structurally and functionally five different DNMT enzymes have been identified in mammals, including DNMT1, DNMT2, DNMT3A, DNMT3B and DNMT3L. These enzymes mainly play roles in two DNA methylation processes: maintenance and de novo. While DNMT1 is primarily responsible for maintenance methylation via transferring methyl groups to the hemi-methylated DNA strands following DNA replication, both DNMT3A and DNMT3B are capable of methylating unmodified cytosine residues, known as de novo methylation. However, DNMT3L indirectly participates in de novo methylation, and DNMT2 carries out methylation of the cytosine 38 in the anticodon loop of aspartic acid transfer RNA. To date, many studies have been performed to determine spatial and temporal expression levels and functional features of the DNMT in the male germ cells. This review article comprehensively discusses dynamic expression of the DNMT during spermatogenesis and their relationship with male infertility development in the light of existing investigations. PMID- 27687054 TI - Effects of Trans-Resveratrol on hyperglycemia-induced abnormal spermatogenesis, DNA damage and alterations in poly (ADP-ribose) polymerase signaling in rat testis. AB - Diabetes induces oxidative stress, DNA damage and alters several intracellular signaling pathways in organ systems. This study investigated modulatory effects of Trans-Resveratrol on type 1 diabetes mellitus (T1DM)-induced abnormal spermatogenesis, DNA damage and alterations in poly (ADP-ribose) polymerase (PARP) signaling in rat testis. Trans-Resveratrol administration (5mg/kg/day, ip) to Streptozotocin-induced T1DM adult male Wistar rats from day 22-42 resulted in recovery of induced oxidative stress, abnormal spermatogenesis and inhibited DNA synthesis, and led to mitigation of 8-hydroxy-2'-deoxyguanosine formation in the testis and spermatozoa, and DNA double-strand breaks in the testis. Trans Resveratrol aggravated T1DM-induced up-regulation of aminoacyl tRNA synthetase complex-interacting multifunctional protein 2 expression; however, it did not modify the up-regulated total PARP and down-regulated PARP1 expressions, but recovered the decreased SirT1 (Sirtuin 1) levels in T1DM rat testis. Trans Resveratrol, when given alone, reduced the poly (ADP-ribosyl)ation (pADPr) process in the testis due to an increase in PAR glycohydrolase activity, but when given to T1DM rats it did not affect the pADPr levels. T1DM with or without Trans Resveratrol did not induce nuclear translocation of apoptosis-inducing factor and the formation of 50 kb DNA breaks, suggesting to the lack of caspase-3 independent cell death called parthanatos. T1DM with or without Trans-Resveratrol did not increase necrotic cell death in the testis. Primary spermatocytes, Sertoli cells, Leydig cells and intra-testicular vessels showed the expression of PARP pathway related proteins. In conclusion, Trans-Resveratrol mitigates T1DM induced sperm abnormality and DNA damage, but does not significantly modulate PARP signaling pathway, except the SirT1 expression, in the rat testis. PMID- 27687055 TI - Dapoxetine attenuates testosterone-induced prostatic hyperplasia in rats by the regulation of inflammatory and apoptotic proteins. AB - Serotonin level plays a role in suppressing the pathological findings of benign prostatic hyperplasia (BPH). Thus a new selective serotonin reuptake inhibitor, dapoxetine was used to test its ability to ameliorate the pathological changes in the rat prostate. A dose response curve was constructed between the dose of dapoxetine and prostate weight as well as relative prostate weight, then a 5mg/kg dose was used as a representative dose for dapoxetine administration. Rats were divided into four groups; the control group that received the vehicle; the BPH induced group received daily s.c injection of 3mg/kg testosterone propionate dissolved in olive oil for four weeks; BPH-induced group treated with finasteride 5mg/kg/day p.o and BPH-induced group treated with dapoxetine 5mg/kg/day p.o. Injection of testosterone increased prostate weight and relative prostate weight which were both returned back to the normal value after treatment with dapoxetine as well as finasteride. Testosterone also upregulated androgen receptor (AR) and proliferating cell nuclear antigen gene expression. Furthermore, testosterone injection elevated cyclooxygenase-II (COX II), inducible nitric oxide synthase (iNOS), B-cell lymphoma-2 (Bcl2) expression and tumor necrosis factor alpha content and reduced caspase-3 activity, Bcl-2-associated X protein (Bax) expression and Bax/Bcl2 ratio. Dapoxetine and finasteride administration reverted most of the changes made by testosterone injection. In conclusion, the current study provides an evidence for the protective effects of dapoxetine against testosterone-induced BPH in rats. This can be attributed, at least in part, to decreasing AR expression, and the anti-proliferative, anti-inflammatory and pro apoptotic activities of dapoxetine in BPH. PMID- 27687056 TI - Training in surgery of the temporomandibular joint: the UK trainers' perspective. AB - Surgery of the temporomandibular joint (TMJ) is increasingly recognised as a subspecialist area of interest within our specialty and many procedures such as arthroscopy, arthroplasty, and replacement of the TMJ are becoming increasingly centralised and restricted to certain regions. We previously made a national survey of trainees and have sought to augment this with a survey of trainers to find out the nature of practice and patterns of referral nationally. We have also examined the consultants' expectations of competent final-year trainees. To do this we made an electronic survey of Fellows of the British Association of Oral and Maxillofacial Surgeons (BAOMS) and received 82 responses (26%). Many just provided simple treatments within their clinical practice, only 16 did arthroscopy, and 14 alloplastic joint replacements. From those who answered the question, only 10 would allow a competent final-year trainee to do an alloplastic joint replacement under supervision. Referrals for TMJ subspecialist care were predominantly made to the West Midlands, East Midlands, and North West, with 24 respondents stating they would either refer open TMJ surgery centrally within or outside the region. Centralisation of services means that training opportunities in surgery of the TMJ are reduced, and restricted to only a few regions. Other models of training may need to be introduced such as simulation, "taster" sessions, and brief clinical attachments. For the budding subspecialist, however, a dedicated Fellowship may become essential to ensure adequate exposure before starting independent consultant practice. PMID- 27687057 TI - Relationship of Modic Changes, Disk Herniation Morphology, and Axial Location to Outcomes in Symptomatic Cervical Disk Herniation Patients Treated With High Velocity, Low-Amplitude Spinal Manipulation: A Prospective Study. AB - OBJECTIVE: The purpose of this study was to evaluate whether cervical disk herniation (CDH) location, morphology, or Modic changes (MCs) are related to treatment outcomes. METHODS: Magnetic resonance imaging (MRI) and outcome data from 44 patients with CDH treated with spinal manipulative therapy were evaluated. MRI scans were assessed for CDH axial location, morphology, and MCs. Pain (0-10 for neck and arm) and Neck Disability Index (NDI) data were collected at baseline; 2 weeks; 1, 3, and 6 months; and 1 year. The Patient's Global Impression of Change data were collected at all time points and dichotomized into "improved," yes or no. Fischer's exact test compared the proportion improved with MRI abnormalities. Numerical rating scale and NDI scores were compared with MRI abnormalities at baseline and change scores at all time points using the t test or Mann-Whitney U test. RESULTS: Patients who were Modic positive had higher baseline NDI scores (P = .02); 77.8% of patients who were Modic positive and 53.3% of patients who were Modic negative reported improvement at 2 weeks (P = .21). Fifty percent of Modic I and 83.3% of Modic II patients were improved at 2 weeks (P = .07). At 3 months and 1 year, all patients with MCs were improved. Patients who were Modic positive had higher NRS and NDI change scores. Patients with central herniations were more likely to improve only at the 2-week time point (P = .022). CONCLUSIONS: Although patients who were Modic positive had higher baseline NDI scores, the proportion of these patients improved was higher for all time points up to 6 months. Patients with Modic I changes did worse than patients with Modic II changes at only 2 weeks. PMID- 27687058 TI - Claudin-1 Protein Expression Is a Good Prognostic Factor in Non-Small Cell Lung Cancer, but only in Squamous Cell Carcinoma Cases. AB - The aim of the study was to investigate the correlation between claudin (CLDN) protein expression and clinicopathological parameters as well as survival in histological subtypes of non-small cell lung cancer. Archived surgical resection specimens of 137 pathologic stage I primary bronchial cancers including 49 adenocarcinomas of non-lepidic variants (ADC), 46 adenocarcinomas of lepidic variants (L-ADC), and 42 squamous cell carcinomas (SCC) were examined. Immunohistochemistry (IHC) using antibodies against CLDN1,-2,-3,-4,-7 proteins as well as semiquantitative estimation (IHC scores 0-5) were performed. Claudin IHC scores of L-ADC differed significantly from ADC (CLDN1: p = 0.009, CLDN2: p = 0.005, CLDN3: p = 0.004, CLDN4: p = 0.001, CLDN7: p < 0.001, respectively) and SCC (CLDN1: p < 0.001, CLDN3: p < 0.001, CLDN7: p < 0.001, respectively). Highly significant CLDN3-CLDN4 parallel expression could be demonstrated in ADC and L ADC (p < 0.001 in both), which was not observed in SCC (p = 0.131). ADC and SCC showed no correlation with smoking, whereas in case of L-ADC heavier smoking correlated with higher CLDN3 expression (p = 0.020). Regarding claudin expression and survival, in SCC significant correlation could be demonstrated between CLDN1 IHC positivity and better survival (p = 0.038). In NSCLC as a whole, high CLDN2 expression proved to be a better prognostic factor when compared with cases where CLDN2 IHC score was 0-1 vs. 2-5 (p = 0.009), however, when analyzed separately, none of the histological subgroups showed correlation between CLDN2 expression and overall survival. The claudin expression pattern was significantly different not only between the SCC-ADC and SCC-L-ADC but also between the L-ADC and ADC histological subgroups, which strongly underlines that L-ADC represents a distinct entity within the ADC group. CLDN1 overexpression is a good prognostic factor in NSCLC, but only in the SCC subgroup. PMID- 27687059 TI - Anesthesia and analgesia methods for outpatient anterior cruciate ligament reconstruction. AB - INTRODUCTION: More and more anterior cruciate ligament (ACL) reconstructions are being performed as outpatient surgery in France, because of economic considerations. Postoperative pain is the most common reason for delayed discharge that could require hospitalization, and the main reason for unanticipated hospital admission. The purpose of this study was to define the best anesthesia and analgesia methods for ACL reconstruction. MATERIALS AND METHODS: This was a prospective, multicenter, comparative study performed between January 2014 and April 2015. Inclusion criteria were ACL reconstruction in patients above 15 years of age performed as an outpatient surgical procedure. The anesthesia techniques analyzed were general anesthesia, spinal anesthesia and quadruple nerve blockade. The analgesic methods studied were single-shot nerve blocks, continuous nerve blocks, peri-articular and intra-articular local infiltration analgesia (LIA), non-steroidal anti-inflammatory agents (NSAIDs) and intravenous corticosteroids. The main outcome criterion was pain on a visual analog scale (VAS). The secondary outcome criteria were delayed discharge of a patient who had undergone outpatient surgery, consumption of opioids and complications for the various anesthesia techniques and analgesia methods. RESULTS: In all, 680 patients were included in this study, which was 63% of the ACL reconstruction procedures performed during this period. The study population was 69% male and 31% female, with an average age of 30 years. Twenty-three patients (3.4%) could not be discharged on the day of surgery. No correlation was found with the anesthesia technique used. NSAID treatment was protective relative to delayed discharge (P=0.009), while opioid consumption was a risk factor (P<0.01). There were no differences in the pain levels related to the type of anesthesia. Peri-articular LIA of the hamstring tendon harvest site was effective. Intra-articular LIA did not provide better analgesia. Continuous nerve block had complication rates above 13%. DISCUSSION: All types of anesthesia were compatible with outpatient ACL reconstruction. No gold standard analgesia method can be defined based on this study's findings. However, we recommend multimodal analgesia associating peri-articular LIA or one-shot sensory saphenous nerve block, NSAIDs and corticosteroid treatment, and cryotherapy. LEVEL OF EVIDENCE: II, prospective comparative non-randomized study. PMID- 27687060 TI - Complications in posteromedial arthroscopic suture of the medial meniscus. AB - INTRODUCTION: All-inside posteromedial suture for lesions of the posterior horn of the medial meniscus in anterior cruciate ligament (ACL) repair provides effective freshening and good healing. HYPOTHESIS: The posteromedial portal provides satisfactory healing rates without increasing morbidity or complications rates. MATERIAL AND METHODS: Intra- and postoperative complications were collected for a consecutive single-center series of 132 patients undergoing posteromedial hook suture of the medial meniscus in ACL repair. Meniscal healing was assessed as the rate of recurrence of symptomatic medial meniscus lesions (Barret criteria) and on revision surgery, if any, in terms of the aspect and extent of the iterative lesion. The severity of any sensory disorder was assessed by questionnaire. RESULTS: The intraoperative complications rate was 1.5% (2 saphenous vein punctures). At a mean 31months (range, 28-35months), there was no loss to follow-up. Twelve patients (9%) showed symptomatic recurrence of the medial meniscus lesion, requiring 10 repeat surgeries. In 6 cases (4.5%), the iterative lesion involved a smaller, more central part of the meniscus anterior to the sutures, of "postage-stamp" effect, possibly implicating the suture hook and/or non-absorbable sutures. There were no cases of infection or fistula. Postoperative hematoma occurred in 7% of patients. In total, 1.8% reported dysesthesia areas equal to or greater than the size of a credit card (45cm2). DISCUSSION: Some retears, or "partial failures", may implicate a new lesion caused by the suture hook and possibly prolonged by non-resorbable sutures. Hematoma and sensory disorder rates were comparable to those reported in isolated ACL repair without posteromedial portal. CONCLUSION: The present results show that posteromedial arthroscopic hook suture in posterior medial meniscus tear provides good healing rates without increased morbidity due to the supplementary portal. LEVEL OF EVIDENCE: IV. PMID- 27687061 TI - Pain after out-patient vs. in-patient ACL reconstruction: French prospective study of 1076 patients. AB - BACKGROUND: Anterior cruciate ligament (ACL) repair is increasingly performed on an out-patient basis. In France, however, concern about post-operative pain remains a strong barrier to out-patient ACL repair. The primary objective of this study was to compare post-operative pain after ACL repair as out-patient versus in-patient surgery. The secondary objectives were to assess the time-course of post-operative pain and to identify factors associated with pain intensity. MATERIAL AND METHODS: A multicentre, prospective, comparative, non-randomised study was conducted in France for the French Society for Arthroscopy (SFA) symposium. Patients who underwent primary ACL repair between January 2014 and March 2015 were included if they were eligible for out-patient surgery. The choice between out-patient and in-patient surgery was based on organisational and logistical considerations. Pain intensity was self-evaluated by the patients using a visual analogue scale (VAS), pre-operatively then in the evening after surgery, during the night after surgery, and 1, 3, and 5 days after surgery. The patients performed the evaluations at home using websurvey.fr(r) software. Demographic data, the characteristics of the surgical procedure, and the IKDC and Lysholm scores before and after surgery were collected. RESULTS: Of the 1076 patients included in the study, 680 had out-patient surgery and 396 in-patient surgery. Mean age was 30+/-9 years. The two groups were comparable at baseline. Pain intensity was not significantly different between the two groups at any of the measurement time points. Pain intensity showed a peak on post-operative day 1 that was similar in the two groups. The initial post-operative pain intensity score predicted subsequent pain intensity: patients with VAS scores <2 on the day of surgery also had low pain scores after surgery. In both groups, factors associated with greater pain intensity were age <25 years, high pre-operative pain score, and surgery performed after noon. Neither surgical technique nor concomitant lesions and methods used to treat them were associated with pain intensity. Risk factors for severe post-operative pain (VAS score >7) in the out patient group were younger age, female gender, pre-operative VAS score >3, and tourniquet time >50minutes. CONCLUSION: Pain intensity is similar after out patient and in-patient ACL repair. Concern about pain should not be a barrier to performing ACL repair on an out-patient basis. Our data on the time-course of the pain and factors associated with greater pain intensity should prove useful for improving patient management after ACL repair. LEVEL OF EVIDENCE: Level III, case control study. PMID- 27687062 TI - French prospective multicenter comparative assessment of ambulatory surgery feasibility in anterior cruciate ligament reconstruction. AB - INTRODUCTION: The main objective of this multicenter study was to assess the feasibility of ambulatory surgery in France in anterior cruciate ligament (ACL) reconstructions for any technique or graft used (hamstring, patellar tendon, fascia lata). We hypothesized that a dedicated organization would guarantee the patient's safety. PATIENTS AND METHODS: A multicenter, non-randomized, prospective, comparative study, conducted within the SFA symposium was conducted between January 2014 and March 2015, included all the patients operated on for arthroscopic ACL reconstruction using different surgical techniques. The outpatient group (OP) included patients eligible for day surgery who provided informed consent; the conventional hospitalization group (CH) comprised patients declined for outpatient surgery for organizational reasons. The main outcome was failure of the admission mode defined by hospitalization of a patient undergoing outpatient surgery or rehospitalization within the 1st week after discharge. The secondary outcomes were assessment of pain and postoperative complications. A total of 1076 patients were studied with 680 in the OP group and 396 in the CH group. The mean age was 30years+/-9years. In the CH group, the mean hospital stay was 2.7+/-0.8days. RESULTS: Twenty-three OP patients were hospitalized or rehospitalized (3.4%). Thirty-six (5.2%) early postoperative complications were noted in the OP group and 17 (4.3%) in the CH group (non-significant difference). Mean postoperative pain on D0-D4 and satisfaction were comparable between the two groups. CONCLUSION: This prospective multicenter study observed no serious incidents. In a selected population, the risks are comparable to those of conventional hospitalization. Outpatient ACL surgery is therefore feasible in France in 2016. LEVEL OF PROOF: III: case-control study. PMID- 27687063 TI - Arthroscopic subtalar arthrodesis. AB - Arthroscopic subtalar arthrodesis is gaining in popularity based on evidence of bone fusion in over 90% of cases, with a shorter time to healing, a simpler postoperative course, and fewer complication compared to open surgery. Two arthroscopic techniques have been reported: one with the patient in lateral decubitus and lateral portals and the other with the patient prone and posterior portals. The objective of this technical note is to describe these two techniques, with emphasis on the specific characteristics of each. PMID- 27687064 TI - Functional outcomes after open versus arthroscopic Latarjet procedure: A prospective comparative study. AB - INTRODUCTION: The Latarjet procedure provides effective stabilization of chronically unstable shoulders. Since this procedure is mainly performed in a young athletic population, the functional impact is significant. Published data does not shed light on the time needed to recover work-related or sports-related function. Performing this procedure arthroscopically may improve functional recovery. This led us to carry out a prospective, multicenter study to compare the functional recovery after arthroscopic versus open Latarjet procedure. MATERIAL AND METHODS: Between June and November 2014, 184 patients were included in a prospective multicenter study: 85 in the open group and 99 in the arthroscopy group. The patients were evaluated preoperatively with the WOSI score. The early postoperative pain was evaluated on D3, D7 and D30. The WOSI score was determined postoperatively at 1, 3, 6 and 12 months of follow-up. RESULTS: The functional scores of the shoulder in both cohorts were identical overall preoperatively. In the immediate postoperative period, the arthroscopy group had statistically lower pain levels on D3 and D7. The postoperative WOSI was improved in both groups at 3 months, then continued to improve until it reached a plateau at 1 year. The WOSI score was better in the arthroscopy group at 3 months, but better in the open group at 6 months. CONCLUSION: This study found that a Latarjet procedure performed arthroscopically generates less immediately postoperative pain than when it is performed as an open procedure. The Latarjet procedure (whether open or arthroscopic) improves shoulder function, with normal function returning after 1 year. PMID- 27687065 TI - Anatomical and morphological study of the subcoracoacromial canal. AB - INTRODUCTION: Many clinical anatomy studies have looked into how variations in the acromion, coracoacromial ligament (CAL) and subacromial space are associated with rotator cuff injuries. However, no study up to now had defined anatomically the fibro-osseous canal that confines the supraspinatus muscle in the subcoracoacromial space. Through an anatomical study of the scapula, we defined the bone-related parameters of this canal and its anatomical variations. MATERIALS AND METHODS: This study on dry bones involved 71 scapulas. With standardised photographs in two orthogonal views (superior and lateral), the surface area of the subcoracoacromial canal and the anatomical parameters making up this canal were defined and measured using image analysis software. The primary analysis evaluated the anatomical parameters of the canal as a function of three canal surface area groups; the secondary analysis looked into how variations in the canal surface area were related to the type of acromion according to the Bigliani classification. RESULTS: Relative to glenoid width, the group with a large canal surface area (L) had significantly less lateral overhang of the acromion than the group with a small canal surface area (S), with ratios of 0.41+/-0.23 and 0.58+/-0.3, respectively (P=0.04). The mean length of the CAL was 46+/-8mm in the L group and 39+/-9mm in the S group (P=0.003). The coracoacromial arch angle was 38 degrees +/-11 degrees in the L group and 34 degrees +/-9 degrees in the S group; the canal surface area was smaller in specimens with a smaller coracoacromial arch angle (P=0.20). CONCLUSION: Apart from acromial morphology, there could be innate anatomical features of the scapula that predispose people to extrinsic lesions to the supraspinatus tendon (lateral overhang, coracoacromial arch angle) by reducing the subcoracoacromial canal's surface area. LEVEL OF EVIDENCE: Anatomical descriptive study. PMID- 27687066 TI - Four novel polymorphisms of buffalo INSIG2 gene are associated with milk production traits in Chinese buffaloes. AB - Insulin-induced genes (INSIGs), including INSIG1 and INSIG2, are important mediators that play a pivotal role in the lipid metabolism and could cause the retention of the SCAP/SREBP complex. Therefore, the objective of this study is to detect the single nucleotide polymorphisms (SNPs) of buffalo INSIG2 gene and evaluate their associations with milk production traits in Chinese buffaloes. A total of four SNPs (g.621272A > G, g.621364A > C, g.632543G > A, and g.632684C > T) were identified using DNA pooled sequencing, and the SNP genotyping for the identified SNPs was performed by using Matrix-assisted laser desorption/ionization time of flight mass spectrometry method from 264 individuals. The results showed that four SNPs were significantly associated with 305-day milk yield or protein percentage in Murrah and crossbred breeds (P < 0.05), but they had no significant effect on milk production traits in Nili-Ravi buffaloes (P > 0.05). Linkage disequilibrium (LD) analysis revealed that one haplotype block was successfully constructed, of which the diplotype H1H1 showed significant association with 305-day milk yield in Murrah buffaloes (P < 0.05). Our findings provide evidence that polymorphisms in buffalo INSIG2 gene are associated with milk production traits, and could be used as a candidate gene for marker-assisted selection in buffalo breeding program.

AB - OPINION STATEMENT: Prosthesis-patient mismatch (PPM) occurs when the effective orifice area (EOA) of a normally functioning prosthesis is too small in relation to the patient's body size, resulting in abnormally high postoperative gradients. PPM is frequent following aortic valve replacement (AVR), and it is associated with increased risk of morbidity and mortality proportionally to its severity. Differential diagnosis between PPM and prosthetic valve stenosis is made by comparing the measured valve effective orifice area, by assessing the changes in valve area and gradient during follow-up and by evaluating leaflet morphology and mobility. Preventive strategies to avoid or minimize PPM should be implemented especially in the patients who are at high risk for severe PPM and in those who have vulnerability factors to PPM. Transcatheter AVR may be superior to surgical AVR for the prevention of PPM and associated adverse cardiac events, particularly in the subset of patients with a small (<21 mm) aortic annulus. In this article, we discuss the most updated data regarding the diagnosis, clinical impact, and prevention of PPM after AVR.

PMID- 27687074 TI - Carbapenemase-producing Enterobacteriaceae in the UK: a national study (EuSCAPE UK) on prevalence, incidence, laboratory detection methods and infection control measures. AB - OBJECTIVES: To estimate UK prevalence and incidence of clinically significant carbapenemase-producing Enterobacteriaceae (CPE), and to determine epidemiological characteristics, laboratory methods and infection prevention and control (IPC) measures in acute care facilities. METHODS: A 6 month survey was undertaken in November 2013-April 2014 in 21 sentinel UK laboratories as part of the European Survey on Carbapenemase-Producing Enterobacteriaceae (EuSCAPE) project. Up to 10 consecutive, non-duplicate, clinically significant and carbapenem-non-susceptible isolates of Escherichia coli or Klebsiella pneumoniae were submitted to a reference laboratory. Participants answered a questionnaire on relevant laboratory methods and IPC measures. RESULTS: Of 102 isolates submitted, 89 (87%) were non-susceptible to >=1 carbapenem, and 32 (36%) were confirmed as CPE. CPE were resistant to most antibiotics, except colistin (94% susceptible), gentamicin (63%), tigecycline (56%) and amikacin (53%). The prevalence of CPE was 0.02% (95% CI = 0.01%-0.03%). The incidence of CPE was 0.007 per 1000 patient-days (95% CI = 0.005-0.010), with north-west England the most affected region at 0.033 per 1000 patient-days (95% CI = 0.012-0.072). Recommended IPC measures were not universally followed, notably screening high risk patients on admission (applied by 86%), using a CPE 'flag' on patients' records (70%) and alerting neighbouring hospitals when transferring affected patients (only 30%). Most sites (86%) had a laboratory protocol for CPE screening, most frequently using chromogenic agar (52%) or MacConkey/CLED agars with carbapenem discs (38%). CONCLUSIONS: The UK prevalence and incidence of clinically significant CPE is currently low, but these MDR bacteria affect most UK regions. Improved IPC measures, vigilance and monitoring are required. PMID- 27687075 TI - Active follow-up versus passive linkage with cancer registries for case ascertainment in a cohort. AB - BACKGROUND: Ascertaining incident cancers is a critical component of cancer focused epidemiologic cohorts and of cancer prevention trials. Potential methods: for cancer case ascertainment include active follow-up and passive linkage with state cancer registries. Here we compare the two approaches in a large cancer screening trial. METHODS: The Prostate, Lung, Colorectal and Ovarian (PLCO) cancer screening trial enrolled 154,955 subjects at ten U.S. centers and followed them for all-cancer incidence. Cancers were ascertained by an active follow-up process involving annual questionnaires, retrieval of records and medical record abstracting to ascertain and confirm cancers. For a subset of centers, linkage with state cancer registries was also performed. We assessed the agreement of the two methods in ascertaining incident cancers from 1993 to 2009 in 80,083 subjects from six PLCO centers where cancers were ascertained both by active follow-up and through linkages with 14 state registries. RESULTS: The ratio (times 100) of confirmed cases ascertained by registry linkage compared to active follow-up was 96.4 (95% CI: 95.1-98.2). Of cancers ascertained by either method, 86.6% and 83.5% were identified by active follow-up and by registry linkage, respectively. Of cancers missed by active follow-up, 30% were after subjects were lost to follow-up and 16% were reported but could not be confirmed. Of cancers missed by the registries, 27% were not sent to the state registry of the subject's current address at the time of linkage. CONCLUSION: Linkage with state registries identified a similar number of cancers as active follow-up and can be a cost effective method to ascertain incident cancers in a large cohort. PMID- 27687076 TI - Self-reported illness among Boston-area international travelers: A prospective study. AB - BACKGROUND: The Boston Area Travel Medicine Network surveyed travelers on travel related health problems. METHODS: Travelers were recruited 2009-2011 during pre travel consultation at three clinics. The investigation included pre-travel data, weekly during-travel diaries, and a post-travel questionnaire. We analyzed demographics, trip characteristics, health problems experienced, and assessed the relationship between influenza vaccination, influenza prevention advice, and respiratory symptoms. RESULTS: Of 987 enrolled travelers, 628 (64%) completed all surveys, of which 400 (64%) reported health problems during and/or after travel; median trip duration was 12 days. Diarrhea affected the most people during travel (172) while runny/stuffy nose affected the most people after travel (95). Of those with health problems during travel, 25% stopped or altered plans; 1% were hospitalized. After travel, 21% stopped planned activities, 23% sought physician or other health advice; one traveler was hospitalized. Travelers who received influenza vaccination and influenza prevention advice had lower rates of respiratory symptoms than those that received influenza prevention advice alone (18% vs 28%, P = 0.03). CONCLUSIONS: A large proportion of Boston-area travelers reported health problems despite pre-travel consultation, resulting in inconveniences. The combination of influenza prevention advice and influenza immunization was associated with fewer respiratory symptoms than those who received influenza prevention advice alone. PMID- 27687077 TI - A proposal for a test method for assessment of hazard property HP 12 ("Release of an acute toxic gas") in hazardous waste classification - Experience from 49 waste. AB - A stepwise method for assessment of the HP 12 is proposed and tested with 49 waste samples. The hazard property HP 12 is defined as "Release of an acute toxic gas": waste which releases acute toxic gases (Acute Tox. 1, 2 or 3) in contact with water or an acid. When a waste contains a substance assigned to one of the following supplemental hazards EUH029, EUH031 and EUH032, it shall be classified as hazardous by HP 12 according to test methods or guidelines (EC, 2014a, 2014b). When the substances with the cited hazard statement codes react with water or an acid, they can release HCl, Cl2, HF, HCN, PH3, H2S, SO2 (and two other gases very unlikely to be emitted, hydrazoic acid HN3 and selenium oxide SeO2 - a solid with low vapor pressure). Hence, a method is proposed:For a set of 49 waste, water addition did not produce gas. Nearly all the solid waste produced a gas in contact with hydrochloric acid in 5 min in an automated calcimeter with a volume >0.1L of gas per kg of waste. Since a plateau of pressure is reached only for half of the samples in 5 min, 6 h trial with calorimetric bombs or glass flasks were done and confirmed the results. Identification of the gases by portable probes showed that most of the tested samples emit mainly CO2. Toxic gases are emitted by four waste: metallic dust from the aluminum industry (CO), two air pollution control residue of industrial waste incinerator (H2S) and a halogenated solvent (organic volatile(s) compound(s)). HF has not been measured in these trials started before the present definition of HP 12. According to the definition of HP 12, only the H2S emission of substances with hazard statement EUH031 is accounted for. In view of the calcium content of the two air pollution control residue, the presence of calcium sulphide (EUH031) can be assumed. These two waste are therefore classified potentially hazardous for HP 12, from a total of 49 waste. They are also classified as hazardous for other properties (HP 7, 10and14 for one of them, and HP 10and14 for the other one respectively). Given these results, it can be assumed that few common household and industrial waste will be classified hazardous only by HP 12. PMID- 27687078 TI - Where next on e-waste in Australia? AB - For almost two decades waste electrical and electronic equipment, WEEE or e waste, has been considered a growing problem that has global consequences. The value of recovered materials, primarily in precious and base metals, has prompted some parts of the world to informally and inappropriately process e-waste causing serious environmental and human health issues. Efforts in tackling this issue have been limited and in many ways unsuccessful. The global rates for formal e waste treatment are estimated to be below the 20% mark, with the majority of end of-life (EoL) electronic devices still ending up in the landfills or processed through rudimentary means. Industrial confidentiality regarding device composition combined with insufficient reporting requirements has made the task of simply characterizing the problem difficult at a global scale. To address some of these key issues, this paper presents a critical overview of existing statistics and estimations for e-waste in an Australia context, including potential value and environmental risks associated with metals recovery. From our findings, in 2014, on average per person, Australians purchased 35kg of electrical and electronic equipment (EEE) while disposed of 25kg of WEEE, and possessed approximately 320kg of EEE. The total amount of WEEE was estimated at 587kt worth about US$ 370million if all major metals are fully recovered. These results are presented over the period 2010-2014, detailed for major EEE product categories and metals, and followed by 2015-2024 forecast. Our future projection, with the base scenario fixing EEE sales at 35kg per capita, predicts stabilization of e-waste generation in Australia at 28-29kg per capita, with the total amount continuing to grow along with the population growth.

AB - OBJECTIVES: To explore current use and perceptions of glove and gown use in nursing homes. DESIGN: Qualitative study using focus groups and semi-structured interviews. SETTING: Three community-based nursing homes in Maryland. PARTICIPANTS: Direct care staff, administrators, and residents. METHODS: We conducted three focus groups among nursing home staff, one focus group among nursing home administrators, and five interviews with residents. Topic guides were created based on our recent study results and a review of the literature. Two investigators separately analyzed the transcribed recordings and identified recurrent themes. RESULTS: Direct care staff reported using gowns and gloves primarily as self-protection against contact with bodily fluids, not to prevent MRSA transmission. Glove use was described as common and more acceptable to staff and residents than gown use. Administrators were surprised that MRSA transmission to health care worker hands and clothing occurred during activities when direct care staff perceives no contact with bodily fluids. Staff and administrators expressed willingness to use gowns and gloves for high-risk care activities, particularly if use is targeted toward specific types of residents such as those with pressure ulcers. There was a knowledge deficit about MRSA transmission and infection among direct care staff and residents. CONCLUSIONS: Results from this study will inform a strategy to reduce MRSA transmission in long-term care. PMID- 27687080 TI - Natural selection? The evolution of diagnostic criteria for gestational diabetes. AB - Gestational diabetes is a common pregnancy disorder which is generally managed with diet, exercise, metformin or insulin treatment and which usually resolves after delivery of the infant. Identifying and treating gestational diabetes improves maternal and fetal outcomes and allows for health promotion to reduce the mother's risk of type 2 diabetes in later life. However, there remains considerable controversy about the optimal method of identification and diagnosis of women with gestational diabetes. The NICE-2015 diagnostic criteria (75 g oral glucose tolerance test (OGTT) 0 h >=5.6 mmol/L; 2 h >=7.8 mmol/L) are based upon cost-effectiveness estimates using observational data, while the WHO-2013 criteria (75 g OGTT 0 h >=5.1 mmol/L; 1 h >=10.0 mmol/L; 2 h >=8.5 mmol/L) identify women and infants at risk of adverse outcomes according to prospective data. There is also considerable controversy about testing for gestational diabetes using universal or risk factor-based screening, and when and how testing should be performed. The aim of this review is to provide a summary of the clinical biochemistry aspects to these debates and to highlight the importance of appropriate identification of gestational diabetes and subsequent type 2 diabetes in this population. PMID- 27687083 TI - Evaluation of a reduced centrifugation time and higher centrifugal force on various general chemistry and immunochemistry analytes in plasma and serum. AB - Background Centrifugation of blood samples is an essential preanalytical step in the clinical biochemistry laboratory. Centrifugation settings are often altered to optimize sample flow and turnaround time. Few studies have addressed the effect of altering centrifugation settings on analytical quality, and almost all studies have been done using collection tubes with gel separator. Methods In this study, we compared a centrifugation time of 5 min at 3000 * g to a standard protocol of 10 min at 2200 * g. Nine selected general chemistry and immunochemistry analytes and interference indices were studied in lithium heparin plasma tubes and serum tubes without gel separator. Results were evaluated using mean bias, difference plots and coefficient of variation, compared with maximum allowable bias and coefficient of variation used in laboratory routine quality control. Results For all analytes except lactate dehydrogenase, the results were within the predefined acceptance criteria, indicating that the analytical quality was not compromised. Lactate dehydrogenase showed higher values after centrifugation for 5 min at 3000 * g, mean bias was 6.3 +/- 2.2% and the coefficient of variation was 5%. Conclusions We found that a centrifugation protocol of 5 min at 3000 * g can be used for the general chemistry and immunochemistry analytes studied, with the possible exception of lactate dehydrogenase, which requires further assessment. PMID- 27687081 TI - Falsely elevated serum oestradiol due to exemestane therapy. AB - In this study, we present a case of falsely elevated oestradiol (E2) concentration, determined by two immunoassays, in a breast cancer patient receiving exemestane therapy. The positive bias of immunochemical measurements was revealed using liquid chromatography tandem mass spectrometry which showed undetectable E2 concentration. The discrepancy is expected to be a consequence of the structural resemblance of E2 and exemestane sharing the same steroidal backbone. Inaccurate laboratory findings in therapy monitoring, as in this case, may lead to unnecessary changes of therapy. PMID- 27687082 TI - Elevated concentrations of hypoxia-inducible factor-1alpha in patients with fracture and concomitant traumatic brain injury. AB - Background Compelling evidence indicate that traumatic brain injury is highly related to accelerated bone fracture repair, but the underlying mechanism still remains elusive. Fracture repair process relies greatly on the formation of new blood vessels in fracture site, and angiogenic factors have been confirmed to be essential for the initiation and maintenance of the fracture healing. Hypoxia inducible factor-1alpha was demonstrated to be a critical regulator of angiogenic osteogenic coupling during bone development and regeneration. The aim of the present study was to investigate the local and circulating concentrations of hypoxia-inducible factor-1alpha in patients with long-bone fractures and concomitant traumatic brain injury and to determine the potential role of hypoxia inducible factor-1alpha in fracture healing. Methods Twenty-five patients with a long-bone fracture and concomitant traumatic brain injury (FT group) and 33 without a brain injury (Fr group) were enrolled in this study. Healthy subjects donated serum samples as control. Serum samples were collected over a period of six months, following a standardized time schedule. Hypoxia-inducible factor 1alpha concentrations were measured in fracture haematoma and serum of patients in both groups using enzyme-linked immunosorbent assay. Results Patients in FT group had a short time to union. Serum hypoxia-inducible factor-1alpha concentrations elevated in the early healing period and reached the maximum level during intramembranous bone formation phase in both groups. Thereafter, it decreased continuously and approached to the minimum levels until the end of the observation period. Serum hypoxia-inducible factor-1alpha concentrations in both groups were significantly higher compared with controls and hypoxia-inducible factor-1alpha concentrations in both serum and fracture haematoma were higher in FT group than that in Fr group. Fracture haematoma contained significantly higher hypoxia-inducible factor-1alpha concentrations compared with hypoxia-inducible factor-1alpha concentrations in serum. Serum hypoxia-inducible factor-1alpha concentrations had a positive correlation with hypoxia-inducible factor-1alpha concentrations in fracture haematoma in patients with fractures. Conclusions These findings suggest the local and systemic involvement of hypoxia-inducible factor-1alpha in fracture healing and the accelerated fracture repair in patients with traumatic brain injury might be associated with elevated hypoxia-inducible factor-1alpha concentrations in fracture haematoma and serum. PMID- 27687084 TI - Assessment of a semi-quantitative screening method for diagnosis of ethylene glycol poisoning. AB - Background Ethylene glycol poisoning remains a rare but important presentation to acute toxicology units. Guidelines recommended that ethylene glycol should be available as an 'urgent' test within 4 h, but these are difficult to deliver in practice. This study assessed a semi-quantitative enzymatic spectrophotometric assay for ethylene glycol compatible with automated platforms. Methods The ethylene glycol method was assessed in 21 samples from patients with an increased anion gap and metabolic acidosis not due to ethylene glycol ingestion, and seven samples known to contain ethylene glycol. All samples were analysed in random order in a blinded manner to their origin on a laboratory spectrophotometer. Results In this study, seven samples were known to contain ethylene glycol at concentrations >100 mg/L. The method correctly identified all seven samples as containing ethylene glycol. No false-positives were observed. Thirteen samples gave clear negative results. Ethylene glycol was present at <20 mg/L in one sample, but this sample remained within the limits of the negative control. Passing-Bablock correlation of estimates of ethylene glycol concentration against results obtained when the samples had been analysed using the quantitative method on an automated analyser showed a good correlation (R = 0.84) but with an apparent under-recovery. Conclusions A semi-quantitative assay for ethylene glycol was able to discriminate well between samples containing ethylene glycol and those with other causes of acidosis. It is a practical small-scale assay for rapid identification of cases of ethylene glycol poisoning. PMID- 27687085 TI - Risk factors for recurrent injurious falls that require hospitalization for older adults with dementia: a population based study. AB - BACKGROUND: Older adults with dementia are at an increased risk of falls, however, little is known about risk factors for recurrent injurious falls (a subsequent fall after the first fall has occurred) among this group. This study aimed to identify risk factors for recurrent injurious falls requiring hospitalization among adults aged 60+ years with dementia. METHODS: This retrospective, whole-population cohort study was conducted using the Western Australian Hospital Morbidity Data System and Western Australian Death Registrations from 2001 to 2013. Survival analysis using a stratified conditional Cox model (type 1) was undertaken to identify risk factors for recurrent injurious falls requiring hospitalization. RESULTS: There were 32,519 participants with an index hospital admission with dementia during the study period. Over 27 % (n = 8970) of the cohort experienced a total of 11,073 injurious falls requiring hospitalization during follow up with 7297 individuals experiencing a single fall, 1330 experiencing two falls and 343 experiencing three or more falls. The median follow-up time for each individual was 2.49 years. Females were at a significantly increased risk of 7 % for recurrent injurious falls resulting in hospitalization (adjusted hazard ratio 1.07, 95 % CI 1.01-1.12), compared to males. Increasing age, living in rural areas, and having an injurious fall in the year prior to the index hospital admission with dementia also increased the risk of recurrent injurious falls resulting in hospitalization. CONCLUSIONS: Screening those with dementia for injurious falls history could help to identify those most at risk of recurrent injurious falls. Improvement of heath care and falls prevention services for those with dementia who live in rural areas may also reduce recurrent injurious falls. PMID- 27687086 TI - Ships as future floating farm systems? AB - Environmental and agriculture challenges such as severe drought, desertification, sprawling cities and shrinking arable lands in large regions in the world compel us to think about alternative and sustainable farming systems. Ongoing projects to build floating cities in the sea suggest that building specific ships for farming purposes (as farming ships or farming boats) would also be attainable to introduce new farming surfaces and boost food production worldwide to cope with food insecurity issues.

PMID- 27687088 TI - Possible role of chromatin alteration in the radiosensitivity of ataxia telangiectasia. AB - Cells derived from individuals with ataxia-telangiectasia (A-T) are known to exhibit increased sensitivity to ionizing radiation and certain radiomimetic chemical agents. Here we summarize our findings regarding the role of chromosome damage and repair in this radiosensitivity. Lymphoblas- toid cells derived from A T homozygotes were characterized for initial chromosome (premature chromosome condensation) and DNA (neutral filter elution) damage and repair kinetics in cells from G1 and G2 cell cycle phases. Despite initial levels of DNA damage being similar to normal controls, A-T cells exhibited nearly a two-fold higher initial amount of chromosome damage. Different A-T cell lines exhibited differing chromosome repair capacities compared with control lymphoblastoid cell lines. These results suggest that A-T cells have an altered chromatin structure whereby DNA double-strand breaks are apparently more efficiently converted into chromosome breaks. Four A-T heterozygote cell lines were examined for chromosome damage and repair in the same fashion and all exhibited increased levels of chromosome damage, although the degree of sensitivity was more prominent in G2 phase cells (two-fold higher) than in G1 phase cells (1-5-fold higher than normal controls). These results suggest that A-T heterozygotes also exhibit an altered chromatin structure which impacts on chromosome damage expression. Of interest, A T cells also exhibited increased chromosome stickiness after irradiation, and telomere regions appeared to be frequently involved. While the molecular basis for preferential telomere involvement is not understood, these results again suggest that structural alterations in the chromatin of A-T cells may play an important role in A-T radiosensitivity. PMID- 27687089 TI - Enhanced chromosomal response of ataxia-telangiectasia cells to specific types of DNA double-strand breaks. AB - The chromosomal response of two ataxiatelangiectasia (A-T) lymphoblastoid cell lines (A-T-PA and A-T-KM) to restriction endonucleases (RE) is compared with that of a normal (N-SW) lymphoblastoid cell line. The RE used were PvuII (generating DNA double-strand breaks with blunt termini), BamHI (cohesive termini with 4 base, 5' overhangs) and PstI (cohesive termini with 4 base 3' overhangs). Chromatid aberrations were analysed in cells 5 h after treatment. Cells were porated using streptolysin O to allow entry of RE. Both A-T lines showed an enhanced frequency of chromatid breaks in G2 phase compared with normal cells in response to RE. The enhanced response of A-T cells was most marked in the case of PvuII treatment when the enhancement ratios were 2-5 and 4-2 for A-T-PA and A-T KM respectively. However, the frequency of DNA double-strand breaks (dsb), measured by neutral filter elution, were considerably lower in A-T-PA cells than N-SW, due to a lower efficiency of poration. When A-T- PA cells were treated with streptolysin O at a higher concentration (0-3 Units/ml), a condition that apparently led to a similar level of poration in A-T-PA as in N-SW cells treated with 0-06 Units/ml as judged by the similar number of dsb induced in the two lines for a given PvuII concentration, the enhancement ratio for A-T-PA cells treated with PvuII increased from 2-5 to 5-8. BamHI and PstI were found to be less clastogenic in all three cell lines as found previously for Chinese hamster cells, although part of this effect may be due to a lower activity, particularly in the case of PstI. However, even at a 4-6-fold higher concentration, BamHI was still less clastogenic than PvuII. It is concluded that dsb with blunt termini are more clastogenic than those with cohesive termini. The results suggest that the chromosomal sensitivity of A-T cells may result from a defect causing a higher rate of conversion of dsb into chromatid aberrations. PMID- 27687090 TI - Cloning efficiency and spontaneous mutant frequency in circulating T-lymphocytes in ataxia-telangiectasia patients. AB - The mutant frequency at the hprt locus in circulating T-lymphocytes has been determined in 16 ataxia- telangiectasia (A-T) patients, 19 A-T heterozygotes and 12 A-T sibs. Mutant frequency in the A-T patients is highly significantly elevated as a group, even when the relatively poor cloning efficiency of many of the A-T lymphocyte samples is taken into account. However, within the A-T set, considerable variation in both cloning efficiency and mutant frequency is seen. Cellular radiation sensitivity, measured by clonal survival assays and chromosome breakage, also varies, as do the clinical symptoms of the patients, including the age at which they become wheelchair bound and the severity of their telangiectasia. Here all the information available to us on this group of patients is presented in an attempt to discern if there is any relationship between those cellular characteristics we have observed and the severity of the symptoms and progression of the disease in the patients. Although we feel that it may be relevant that the adult patients in our study all have mutant frequencies that are not highly elevated, insufficient data are available at present to resolve any relationship between the heterogeneous clinical symptoms and cellular responses seen in the A-T patients as a group. PMID- 27687091 TI - The nature of ataxia-telangiectasia: problems and perspectives. PMID- 27687092 TI - Radiation checkpoints in model systems. AB - The response to DNA damaging agents includes a delay to progression through the cell cycle. Irradiation of premitotic cells causes a delay to mitosis and irradiation of Gi and S phase cells causes a delay to DNA synthesis. These delays have become known as checkpoints. The mechanisms that mediate the mitotic (or G2) checkpoint delay have recently come under study in yeast model systems. Work in the eukaryotic organisms S. cerevisiae and S. pombe has identified at least seven proteins controlling the interactions between DNA damage and cell cycle progression. Genetic analysis of this checkpoint pathway has identified substantial overlap with the feedback controls that co-ordinate progression through the cell cycle. Molecular analysis has revealed structural conservation between these highly diverged yeasts, which suggests that similar proteins may act in related pathways in mammalian cells. In addition, the rad24 and rad25 genes of S. pombe (which are involved in the radiation checkpoint) encode functionally overlapping essential proteins that are highly conserved in mammalian cells. Studies of checkpoints in the yeasts may therefore help to define the signal pathways that control cell cycle delay in mammalian cells following irradiation, some of which have been proposed to be deficient in A-T cells. PMID- 27687093 TI - Testing the role of p53 in the expression of genetic instability and apoptosis in ataxia-telangiectasia. AB - We have obtained initial evidence supporting a new model for the human disease ataxia-telangiectasia (A-T), in which the A-T and p53 genes play crucial roles in a signal transduction network that activates multiple cellular functions in response to DNA damage. Three of the model's predictions were tested. (1) Disrupting cell cycle checkpoints should increase spontaneous rates in normal cells. In order to interfere with the G1/S checkpoint, we transfected a normal cell line with vectors expressing either a dominant-negative p53ala143 mutant or a human papilloma virus E6 gene. These transformants showed 10-80-fold elevations in spontaneous recombination rates when compared with their parent. (2) A-T cells should be sensitive to DNA damage-induced apoptosis. Widespread apoptosis was detectable in four A-T fibroblast lines, but not two control lines, beginning 24 h after exposure to X-rays or streptonigrin, but not UV. Streptonigrin also induced widespread apoptosis in A-T lymphoblasts but not in control lymphoblasts. (3) Disruption of p53 function in A-T cells should increase their mutagen resistance by interfering with apoptosis. Stable transfection of either the p53143ala or the HPV18 E6 construct was associated with acquisition of streptonigrin and radiation resistance, while transfection with the p53143ala construct did not affect the streptonigrin sensitivity of a control cell line. PMID- 27687094 TI - Defect in radiation signal transduction in ataxia-telangiectasia. AB - Exposure of mammalian cells to ionizing radiation causes a delay in progression through the cycle at several checkpoints. Cells from patients with ataxia telangiectasia (A-T) ignore these checkpoint controls postirradiation. The tumour suppressor gene product p53 plays a key role at the G1/S checkpoint preventing the progression of cells into S phase. The induction of p53 by radiation is reduced and/or delayed in A-T cells, which appears to account for the failure of delay at the G1/S checkpoint. We have investigated further this defect in radiation signal transduction in A-T. While the p53 response was defective after radiation, agents that interfered with cell cycle progression such as mimosine, aphidicolin and deprivation of serum led to a normal p53 response in A-T cells. None of these agents caused breaks in DNA, as determined by pulse-field gel electrophoresis, in order to elicit the response. Since this pathway is mediated by protein kinases, we investigated the activity of several of these enzymes in control and A-T cells. Ca+2-dependent and -independent protein kinase C activities were increased by radiation to the same extent in the two cell types, a variety of serine/threonine protein kinase activities were approximately the same and anti-tyrosine anti-bodies failed to reveal any differences in protein phosphorylation between A-T and control cells. It is not evident what is the nature of the defect in signal transduction in A-T cells. However, it is clear that the p53 response is normal in these cells after exposure to some agents and it is mediated through protein kinase C or another serine/threonine kinase. PMID- 27687095 TI - Radiation-induced G2 delay and spontaneous chromosome aberrations in ataxia telangiectasia homozygotes and heterozygotes. AB - The extent of cell cycle delay of lymphocytes X-irradiated in G2 phase was measured by mitotic inhibition determinations in 66 controls, 14 ataxia telangiectasia (A-T) homozygotes and 27 obligate heterozygotes, Homozygotes had a significantly reduced mitotic index (MI) in unirradiated samples and showed significantly less radiation-induced mitotic inhibition than controls, This confirms our earlier disputed observations on A-T fibroblasts and demonstrates a G2 checkpoint defect in addition to the well-known defects in S phase and at the G1-S phase transition. There are two separate and opposite abnormal Ga responses of A-T cells; a primary event in which cells in G2 at the time of irradiation suffer less delay than controls, and a secondary event in which cells irradiated at earlier stages of the cycle are more delayed when they pass into G2, The MI of unirradiated heterozygote cells and the extent of mitotic inhibition were indistinguishable from controls. Spontaneous unstable chromosome aberrations were, as previously reported, significantly higher in homozygotes than in controls. This was true for breaks, but not for gaps, There was a suggestion of an increase in breaks in heterozygotes, but a much larger study would be required to confirm or refute this. PMID- 27687096 TI - Prenatal diagnosis of ataxia-telangiectasia and Nijmegen Breakage Syndrome by the assay of radioresistant DNA synthesis. AB - Prenatal diagnosis was performed in 16 pregnancies at risk of ataxia telangiectasia (A-T) or Nijmegen Breakage Syndrome (NBS). Radioresistant DNA synthesis (RDS) was investigated in cultured chorionic villus (CV) cells and/or amniotic fluid (AF) cells. In four pregnancies, an affected foetus was diagnosed with increased RDS in cultured CV cells. In three of the four cases confirmation of the diagnosis was obtained by analysis of AF cells and/or skin fibroblasts from the foetus cultured after termination of the pregnancy; in the fourth case a fibroblast culture from the aborted foetus failed. In one case, only AF cells could be analysed in a late stage of pregnancy; pregnancy was terminated due to intermediate/ equivocal results but the foetal fibroblasts showed normal RDS. Normal RDS was demonstrated in the other 11 pregnancies at 25% risk either by analysis of CV cells (nine cases) or of AF cells (two cases). In some cases the (normal) results on the CV cells were corroborated by subsequent analysis of AF cells. The results suggest that RDS analysis of CV cells allows reliable prenatal diagnosis of A-T/NBS. However, amniocentesis may be necessary to confirm normal results on CV cells if the foetus is female (because of the risk of maternal cell contamination) or in the rare case of equivocal results. PMID- 27687097 TI - Cancer risks in A-T heterozygotes. AB - It is well established that ataxia-telangiectasia (A-T) patients suffer a grossly elevated risk of cancer, particularly lymphoma and leukaemia, but the possibility of an excess cancer risk of cancer in heterozygotes carriers of A-T mutations is more controversial. A number of studies indicate that female relatives of A-T patients suffer excess risk of breast cancer; based on an overview of all currently available data the esti-mated relative risk of breast cancer to A-T heterozygotes is 3.9-fold (95%CI 2.1-7.2). There is some suggestion that relative risk declines with age. In contrast, there is no consistent evidence of a risk from any other cancer; the estimated risk from all studies is 1.9 (95%CI 1.5-2.5) but some studies show a larger effect whilst others show no excess risk. On the basis of these results and the likely frequency of the A-T gene, A-T heterozygotes would account for between 1 and 13% of breast cancer cases, with 3.8% being the best estimate. However, unless the breast cancer risk has been seriously underestimated, the A-T gene will make little contribution to familial breast cancer. PMID- 27687098 TI - Nijmegen Breakage Syndrome: a progress report. AB - We report the findings in the first 30 patients with the Nijmegen Breakage Syndrome (NBS). All had microcephaly from birth, short stature and a 'bird-like' face. Most of them suffered from recurrent respiratory tract infections. Intelligence was normal in half of the patients. Serum immunoglobulins were disturbed in 22/25 patients investigated (IgG deficiency, IgA deficiency, IgG2 and IgG4 deficiency) and T cell defects were found in 23/24 patients tested. The immunodeficiency appears to be more severe than in A-T. Chromosomal aberrations in cultured T lymphocytes occurred preferentially in chromosomes 7 and 14 and at the same breakpoints as in A-T. However, the percentage of chromosome 7 and/or 14 rearrangements was significantly higher in NBS patients than in A-T patients (p < 0.0005). Inv(7) was amongst the most frequently detected aberration in NBS cells as it is in A-T cells. Large clones of cells with rearrangements of chromosome 14 were rare in NBS. Of the first 19 reported patients eight have already developed a malignancy: seven a lymphoma and one a meningioma. It is noteworthy that both the tendency to express rearrangements of chromosomes 7 and 14 and the tendency to develop a malignancy is much higher in NBS than in A-T. Whether there is any causal relationship is as yet unknown. PMID- 27687099 TI - Functional complementation studies with X-ray-sensitive mutants of Chinese hamster cells closely resembling ataxia-telangiectasia cells. AB - In order to isolate a human gene complementing the defect in A-T-like hamster cell mutants, the mutants were used as recipients for genomic DNA transfection, using either HeLa chromosomal DNA or DNA from a human cosmid library. Three primary transformants with an intermediate X-ray sensitivity and almost normal sensitivity to MMS, but retaining radioresistant DNA synthesis (RDS), were obtained. To identify the human chromosome that complements the defect in the A-T like mutants, and to assess the degree of complementation for survival and RDS, microcell-mediated chromosome transfer was used. At least 20 independent hybrid clones between the mutant and each one of the human chromosomes 1, 2, 4, 5, 15, 17 or 18 were isolated. All hybrid clones remained X-ray sensitive, except one with chromosome 4, and another with chromosome 15, both showing an intermediate X ray sensitivity. By using in situ hybridization we found that this partial correction was due to the presence of a mouse chromosome. In these two hybrids containing the mouse chromosome together with human chromosome 4 or 15, RDS was fully complemented only in the hybrid with chromosome 4 but not in the one containing chromosome 15, suggesting that RDS and X-ray sensitivity may be complemented independently. PMID- 27687100 TI - After-thoughts and conclusions on the nature of the A-T gene. PMID- 27687101 TI - Clinical and genetic features of ataxia-telangiectasia. AB - There are several variants of ataxia-telangiectasia (A-T) : classical A-T with marked radiation sensitivity; classical A-T with intermediate levels of radiation sensitivity; mild A-T with intermediate levels of radiation sensitivity; A-T without telangiectasia; A-T without oculomotor apraxia; and A-T with microcephaly. These disorders are probably caused by different allelic mutations, because affected sibs resemble the index patients, and because there is an association of certain haplo- types of 11 q22-23 with specific phenotypes. The Nijmegen Breakage Syndrome, with its lack of ataxia, seems on clinical grounds to be a different disorder. Although A-T is almost always inherited as an autosomal recessive, there are some unusual features; an unexpectedly low parental consanguinity rate, an incidence in sibs that is <0-25, and occurrence of disease in many different races and in the offspring of mixed race unions. Moreover, looking at haplotypes from 63 UK patients, there is a remarkably low incidence of homozygosity. An autosomal recessive condition that is deficient in parental consanguinity, and in homozygosity for the region around the gene, can be explained by J. H. Edwards' hyopothesis that homozygosity for alleles at a neighbouring locus are lethal early in embryogenesis. Other possible mechanisms to explain the unusual genetic features are discussed. PMID- 27687102 TI - Ataxia-telangiectasia in Italy: genetic analysis. AB - Genetic analysis was performed on 72 Italian A-T families ascertained through 91 probands. The frequency of the A-T gene was estimated through Dahlberg's formula, which uses the frequencies of first cousin marriages among the patients' parents and in the general population. Data on consanguinity in the general population were obtained from the collection of Catholic Church dispensations for the period 1910-1964. Accurate estimates of the disease frequency were made by subdividing data into 5-year periods and between provinces, in order to take into account temporal (decrease over time) and spatial (higher frequency in Southern Italy) heterogeneity. The estimate of the gene frequency for the whole sample was q = 0.012 +/- 0.0065, corresponding to a heterozygote frequency of 2*34% and to a disease frequency of 1 in 7090. When considering q before and after 1970, there was an apparent increase of heterozygote frequency from 1.69 to 3.43%, perhaps due to a better ascertainment of the disease in the latter period. A segregation ratio of 0.249 +/- 0.043 was obtained by analyzing the offspring of the 72 families under the model of incomplete multiple selection. This value is not significantly different from 0.25, as expected for an autosomal recessive disease. PMID- 27687104 TI - Genetic and physical mapping of the ataxia-telangiectasia locus on chromosome Ilq22-q23. AB - The identification of A-T gene(s) using both positional and functional cloning techniques has been a major objective in A-T research over the past 10 years. Functional cloning, using complementation of the radiosensitivity phenotype, has met with some success, although technical problems remain to be overcome. Recent progress, however, in both genetic and physical mapping of the A-T locus on chromosome lIq22-q23, described in this review, suggests that the positional cloning of candidate genes should be achieved in the very near future. The region of the chromosome containing the gene(s) has been identified, and is no more than 1-6 Mb in size. The detailed physical characterization of this region, as a preliminary to candidate gene isolation, is now underway. There are, however, still some unresolved issues, most notably the existence of four A-T complementation groups, with the resulting supposition that these equate to a number of different genes. Although genetic linkage evidence does not support the hypothesis of genetic heterogeneity, the possibility of a cluster of genes at the 11 q22-23 locus cannot be ruled out. It is likely that the explanations for this and other problems such as discrepancies in expected levels of consanguinity, and difficulties in the classification of atypical phenotypes will become much more obvious once a gene or genes have been cloned. PMID- 27687103 TI - A haplotype common to intermediate radiosensitivity variants of ataxia telangiectasia in the UK. AB - In a study of ataxia-telangiectasia (A-T) in the UK, patients in 10 out of 60 families were shown to have a much lower level of chromosomal radiosensitivity compared with the majority of patients. In some patients the level of radiosensitivity was hardly distinguishable from normal. Patients in this group, however, could be distinguished clinically from the majority either by the later onset of severe cerebellar features or the slower rate of progress of the disorder. By using highly polymorphic microsatellite repeat markers a chromosome llq22-23 haplotype common to the majority of these patients, and not occurring in any non-A-T chromosome in 60 families, was identified on one chromosome. The haplotype probably defines the region of the A-T gene in these families and the mutation associated with this haplotype may be much less severe than the second mutation thereby producing the slightly milder phenotype.

AB - Genetic heterogeneity in ataxia-telangiectasia (A-T) points to four different genes responsible for this disease. The two major A-T genes, ATA and ATC, were localized by genetic analysis close to each other on chromosome 11q22-23, prompting efforts of positional cloning. Essential steps in positional cloning are long-range cloning of the genomic region of interest, and derivation of highly polymorphic markers that would allow further reduction of the interval carrying the A-T gene. We constructed genomic contigs across the D11S611-D1S424 region harbouring the ATA and ATC genes in yeast artificial chromosome (YAC) vectors. These contigs were used as a fine mapping tool and enabled us to localize along the A-T region, eight microsatellite markers generated randomly by genome mapping centres. In addition, we used specific YAC clones to generate five new microsatellite markers based on polymorphic CA repeats. Recombination mapping based on Israeli A-T families indicates that the ATC gene is distal to the locus D11S1817. Further linkage analysis using these markers is expected to reduce the major A-T locus considerably to a size appropriate for cosmid cloning and identification of transcribed sequences. PMID- 27687106 TI - Genetic haplotyping of ataxia-telangiectasia families localizes the major gene to an ~850 kb region on chromosome 11 q23.1. AB - The genotyping data given localize the major A-T gene to an ~ 850 kb region. They also localize the group A A-T gene (ATA) to a region that contains the ~ 850 kb region. They are compatible with linking A-TFresno to 11 q22-23. NBS-V2 does not link to this region. Four non-linking families contain only single affecteds, suggesting that these may be spontaneous mutations rather than evidence for an A T gene outside the 11 q22-23 region. Finally, two other non-linking families contain recombinant haplotypes that are compatible with a second A-T gene at llq22-23, slightly distal to the ~ 850 kb region. However, convincing evidence for a second gene is still lacking. PMID- 27687108 TI - DNA marker D11S384 shows zero recombination with the ataxia-telangiectasia locus in North American families. AB - At the genetic locus D11S384, one probe detects a Taql RFLP and another detects a RFMP. In 52 pedigrees of North American A-T patients, parental haplotypes based on these two bi-allelic systems have a heterozygosity of 0.69 and a PIC of 0.64. No recombinant events between D11S384 and the A-T locus were detected in the 43 pedigrees in which this marker locus was informative. PMID- 27687109 TI - Expression of a candidate ataxia-telangieetasia group D gene in cultured fibroblast cell lines and human tissues. AB - A candidate gene for ataxia-telangiectasia group D (.ATDC) has been cloned (Kapp et al. 1992), sequenced and found to be a member of a recently reported gene family (Leonhardt et al. 1994). Transcriptional behaviour of ATDC has been examined in a number of cell lines and human tissues using a 3-0 kb cloned cDNA as a probe. Three normal and two ataxia-telangiectasia (A-T) group D, non transformed fibroblast cell lines produced a 2-4 kb mRNA transcript. The size of mRNA transcripts seen and the level of expression differ in different human tissues. Many tissues have multiple transcripts of ATDC and the most prominent transcripts observed were 3'0, 2-4 and 1-6 kb. Two out of three SV-40 transformed normal and one SV-40-transformed A-T group D fibroblast cell lines demonstrated no transcription of ATDC by RNA blotting analysis. These results suggest that SV 40 transformation may affect the expression of ATDC. Reverse transcription- polymerase chain reaction analysis showed that ATDC was expressed at low levels in all of these cells. Additional Northern blot analysis demonstrated that X irradiation with 10 Gy had no effect on ATDC expression at 1, 4 and 24h after irradiation in either SV-40-transformed normal or in SV-40-transformed A-T group D fibroblast cell lines. Further understanding of ATDC will require cloning of additional transcripts and studies of ATDC protein behaviour. PMID- 27687110 TI - Expression of the candidate A-T gene ATDC is not detectable in a human cell line with a normal response to ionizing radiation. AB - Nucleotide sequence analysis of a candidate gene for A-T group D {ATDC) demonstrated that it is related to a group of proteins that contain both zinc finger and leucine zipper motifs. The presence of a leucine zipper suggested that this protein might form homodimers, and this was confirmed by means of the two hybrid system in yeast. The activity of some proteins that form homodimers can be effectively eliminated by overexpression of inactive forms of the protein that bind to the wild-type protein to create a dominant negative phenotype. An ATDC cDNA containing a 37 amino acid deletion in the zinc finger region (ATDCDelta) was therefore transfected into colorectal carcinoma human tumour cells (RKO) to determine whether its expression would produce a response to radiation similar to that seen in A-T cells. RKO cells have been shown to have normal radiosensitivity and cell cycle regulation and, therefore, seemed ideal for this study. Despite the fact that the A-T gene has been found to be important in the radiation damage response, no ATDC mRNA transcripts were detectable in the RKO cell line. In addition, the RKO subclones expressing the ATDCDelta mRNA showed no change in radiosensitivity or cell cycle regulation. These results do not support the conclusion that ATDC is an A-T gene, and suggest that the ATDC protein acts indirectly to suppress radiosensitivity in A-T cells. PMID- 27687111 TI - Cellular radiosensitivity tn ataxia-telangiectasia. AB - Hypersensitivity to both the cell-killing and chromosome-damaging effects of ionizing radiations, and other agents causing DNA breakage, is a consistent feature of cells from individuals with the cancer-prone disorder ataxiatelangiectasia (A-T). Evidence for a defect in DNA strand break rejoining is slight, but a higher-than-normal level of chromosomal breaks persists in irradiated A-T cells. There is also evidence for elevated frequencies of DNA recombination and deletion mutation in A-T cells; these responses may be linked through a loss of fidelity in rejoining DNA breaks through recombination mechanisms. Additionally the regulation of cell-cycle responses is altered in A-T cells: in all phases of the cycle there is some loss of 'checkpoint' function shortly after irradiation, allowing cells to continue cycling despite extensive DNA damage. However, on present evidence, radiation hypersensitivity cannot be explained simply by this loss of regulatory function. It is suggested that the A T gene product acts in the early stages of a DNA damage-recognition pathway, normally interacting with regulatory proteins such as p53, but also with proteins involved in the processing of DNA breaks. Reduced efficiency in this type of signalling function could well explain the link between radiosensitivity and cancer proneness.

AB - I review one aspect of the A-T phenotype, the remarkable and fascinating increase of lymphocytes carrying chromosomal aberrations caused by V(D)J site-specific recombination. The review is organized to first present the facts of V(D)J recombination and the findings in this regard in A-T patients. Other populations that demonstrate similar increases in such chromosomal aberrations are then presented and a hypothesis is offered as to the basis and relevance of these increases vis-a-vis A-T. The contribution of V(D)J recombination to the clonal proliferations and frank lymphoid malignancies seen in A-T patients is briefly discussed. I conclude with some speculative comments extending the observations presented into a more global consideration of a possible function of an A-T gene.

AB - BACKGROUND: Asthma is one of the most common reasons for hospital admission among children and constitutes a significant economic burden. Use of non-invasive positive pressure ventilation (NPPV) in the care of children with acute asthma has increased even though evidence supporting the intervention has been considered weak and clinical guidelines do not recommend the intervention. NPPV might be an effective intervention for acute asthma, but no systematic review has been conducted to assess the effects of NPPV as an add-on therapy to usual care in children with acute asthma. OBJECTIVES: To assess the benefits and harms of NPPV as an add-on therapy to usual care (e.g. bronchodilators and corticosteroids) in children with acute asthma. SEARCH METHODS: We identified trials from the Cochrane Airways Group Specialised Register (CAGR). The Register contains trial reports identified through systematic searches of bibliographic databases, including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, AMED and PsycINFO, and by handsearching of respiratory journals and meeting abstracts. We also conducted a search of ClinicalTrials.gov (www.ClinicalTrials.gov) and the WHO trials portal (www.who.int/ictrp/en/). We searched all databases from their inception to February 2016, with no restriction on language of publication. SELECTION CRITERIA: We included randomised clinical trials (RCTs) assessing NPPV as add-on therapy to usual care versus usual care for children (age < 18 years) hospitalised for an acute asthma attack. DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles and abstracts. We retrieved all relevant full-text study reports, independently screened the full text, identified trials for inclusion and identified and recorded reasons for exclusion of ineligible trials. We resolved disagreements through discussion or, if required, consulted a third review author. We recorded the selection process in sufficient detail to complete a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta analyses) flow diagram and 'Characteristics of excluded studies' table. We identified the risk of bias of included studies to reduce the risk of systematic error. We contacted relevant study authors when data were missing. MAIN RESULTS: We included two RCTs that randomised 20 participants to NPPV and 20 participants to control. We assessed both studies as having high risk of bias; both trials assessed effects of bilateral positive airway pressure (BiPAP). Neither trial used continuous positive airway pressure (CPAP). Controls received standard care. Investigators reported no deaths and no serious adverse events (Grades of Recommendation, Assessment, Development and Evaluation (GRADE): very low quality of evidence due to serious risk of bias and serious imprecision of results). Both trials showed a statistically significant reduction in symptom score. One trial did not report a standard deviation (SD), but by using an estimated SD, we found a statistically significantly reduced asthma symptom score (mean difference (MD) 2.50, 95% confidence interval (CI) -4.70 to -0.30, P = 0.03, 19 participants, GRADE: very low quality of evidence). In the other trial, NPPV was associated with a lower total symptom score (5.6 vs 1.9, 16 participants, very low quality of evidence) before cross-over, but investigators did not report an SD, nor could it be estimated from the first phase of the trial, before the cross-over. These gains could be clinically relevant, as a reduction of three or more points in symptom score is considered a clinically meaningful change. Researchers documented five dropouts (12.5%), four of which were due to intolerance to NPPV, and one to respiratory failure requiring intubation. Owing to insufficient reporting in the latter trial and use of different scoring systems, it was not possible to conduct a meta-analysis nor a Trial Sequential Analysis. AUTHORS' CONCLUSIONS: Current evidence does not permit confirmation or rejection of the effects of NPPV for acute asthma in children. Large RCTs with low risk of bias are warranted. PMID- 27687115 TI - BEN domain protein Elba2 can functionally substitute for linker histone H1 in Drosophila in vivo. AB - Metazoan linker histones are essential for development and play crucial roles in organization of chromatin, modification of epigenetic states and regulation of genetic activity. Vertebrates express multiple linker histone H1 isoforms, which may function redundantly. In contrast, H1 isoforms are not present in Dipterans, including D. melanogaster, except for an embryo-specific, distantly related dBigH1. Here we show that Drosophila BEN domain protein Elba2, which is expressed in early embryos and was hypothesized to have insulator-specific functions, can compensate for the loss of H1 in vivo. Although the Elba2 gene is not essential, its mutation causes a disruption of normal internucleosomal spacing of chromatin and reduced nuclear compaction in syncytial embryos. Elba2 protein is distributed ubiquitously in polytene chromosomes and strongly colocalizes with H1. In H1 depleted animals, ectopic expression of Elba2 rescues the increased lethality and ameliorates abnormalities of chromosome architecture and heterochromatin functions. We also demonstrate that ectopic expression of BigH1 similarly complements the deficiency of H1 protein. Thus, in organisms that do not express redundant H1 isoforms, the structural and biological functions performed by canonical linker histones in later development, may be shared in early embryos by weakly homologous proteins, such as BigH1, or even unrelated, non-homologous proteins, such as Elba2. PMID- 27687116 TI - Experiments with More Than One Random Factor: Designs, Analytic Models, and Statistical Power. AB - Traditional methods of analyzing data from psychological experiments are based on the assumption that there is a single random factor (normally participants) to which generalization is sought. However, many studies involve at least two random factors (e.g., participants and the targets to which they respond, such as words, pictures, or individuals). The application of traditional analytic methods to the data from such studies can result in serious bias in testing experimental effects. In this review, we develop a comprehensive typology of designs involving two random factors, which may be either crossed or nested, and one fixed factor, condition. We present appropriate linear mixed models for all designs and develop effect size measures. We provide the tools for power estimation for all designs. We then discuss issues of design choice, highlighting power and feasibility considerations. Our goal is to encourage appropriate analytic methods that produce replicable results for studies involving new samples of both participants and targets.

There has been a dramatic increase in randomized controlled trials (RCTs) of mindfulness interventions over the past two decades. This article evaluates the growing evidence of mindfulness intervention RCTs by reviewing and discussing (a) the effects of mindfulness interventions on health, cognitive, affective, and interpersonal outcomes; (b) evidence-based applications of mindfulness interventions to new settings and populations (e.g., the workplace, military, schools); (c) psychological and neurobiological mechanisms of mindfulness interventions; (d) mindfulness intervention dosing considerations; and (e) potential risks of mindfulness interventions. Methodologically rigorous RCTs have demonstrated that mindfulness interventions improve outcomes in multiple domains (e.g., chronic pain, depression relapse, addiction). Discussion focuses on opportunities and challenges for mindfulness intervention research and on community applications. PMID- 27687117 TI - Memory: Organization and Control. AB - A major goal of memory research is to understand how cognitive processes in memory are supported at the level of brain systems and network representations. Especially promising in this direction are new findings in humans and animals that converge in indicating a key role for the hippocampus in the systematic organization of memories. New findings also indicate that the prefrontal cortex may play an equally important role in the active control of memory organization during both encoding and retrieval. Observations about the dialog between the hippocampus and prefrontal cortex provide new insights into the operation of the larger brain system that serves memory. PMID- 27687120 TI - Culture Three Ways: Culture and Subcultures Within Countries. AB - Culture can be thought of as a set of everyday practices and a core theme individualism, collectivism, or honor-as well as the capacity to understand each of these themes. In one's own culture, it is easy to fail to see that a cultural lens exists and instead to think that there is no lens at all, only reality. Hence, studying culture requires stepping out of it. There are two main methods to do so: The first involves using between-group comparisons to highlight differences and the second involves using experimental methods to test the consequences of disruption to implicit cultural frames. These methods highlight three ways that culture organizes experience: (a) It shields reflexive processing by making everyday life feel predictable, (b) it scaffolds which cognitive procedure (connect, separate, or order) will be the default in ambiguous situations, and (c) it facilitates situation-specific accessibility of alternate cognitive procedures. Modern societal social-demographic trends reduce predictability and increase collectivism and honor-based go-to cognitive procedures. PMID- 27687121 TI - The Structure of Social Cognition: In(ter)dependence of Sociocognitive Processes. AB - Social cognition is a topic of enormous interest and much research, but we are far from having an agreed taxonomy or factor structure of relevant processes. The aim of this review is to outline briefly what is known about the structure of social cognition and to suggest how further progress can be made to delineate the in(ter)dependence of core sociocognitive processes. We focus in particular on several processes that have been discussed and tested together in typical and atypical (notably autism spectrum disorder) groups: imitation, biological motion, empathy, and theory of mind. We consider the domain specificity/generality of core processes in social learning, reward, and attention, and we highlight the potential relevance of dual-process theories that distinguish systems for fast/automatic and slow/effortful processing. We conclude with methodological and conceptual suggestions for future progress in uncovering the structure of social cognition. PMID- 27687123 TI - How Power Affects People: Activating, Wanting, and Goal Seeking. AB - Sociocognitive research has demonstrated that power affects how people feel, think, and act. In this article, I review literature from social psychology, neuroscience, management, and animal research and propose an integrated framework of power as an intensifier of goal-related approach motivation. A growing literature shows that power energizes thought, speech, and action and orients individuals toward salient goals linked to power roles, predispositions, tasks, and opportunities. Power magnifies self-expression linked to active parts of the self (the active self), enhancing confidence, self-regulation, and prioritization of efforts toward advancing focal goals. The effects of power on cognitive processes, goal preferences, performance, and corruption are discussed, and its potentially detrimental effects on social attention, perspective taking, and objectification of subordinates are examined. Several inconsistencies in the literature are explained by viewing power holders as more flexible and dynamic than is usually assumed. PMID- 27687122 TI - Numerical Development. AB - In this review, we attempt to integrate two crucial aspects of numerical development: learning the magnitudes of individual numbers and learning arithmetic. Numerical magnitude development involves gaining increasingly precise knowledge of increasing ranges and types of numbers: from nonsymbolic to small symbolic numbers, from smaller to larger whole numbers, and from whole to rational numbers. One reason why this development is important is that precision of numerical magnitude knowledge is correlated with, predictive of, and causally related to both whole and rational number arithmetic. Rational number arithmetic, however, also poses challenges beyond understanding the magnitudes of the individual numbers. Some of these challenges are inherent; they are present for all learners. Other challenges are culturally contingent; they vary from country to country and classroom to classroom. Generating theories and data that help children surmount the challenges of rational number arithmetic is a promising and important goal for future numerical development research. PMID- 27687119 TI - Learning, Reward, and Decision Making. AB - In this review, we summarize findings supporting the existence of multiple behavioral strategies for controlling reward-related behavior, including a dichotomy between the goal-directed or model-based system and the habitual or model-free system in the domain of instrumental conditioning and a similar dichotomy in the realm of Pavlovian conditioning. We evaluate evidence from neuroscience supporting the existence of at least partly distinct neuronal substrates contributing to the key computations necessary for the function of these different control systems. We consider the nature of the interactions between these systems and show how these interactions can lead to either adaptive or maladaptive behavioral outcomes. We then review evidence that an additional system guides inference concerning the hidden states of other agents, such as their beliefs, preferences, and intentions, in a social context. We also describe emerging evidence for an arbitration mechanism between model-based and model-free reinforcement learning, placing such a mechanism within the broader context of the hierarchical control of behavior.

AB - Acute disseminated encephalomyelitis is a monophasic demyelinating disorder of the central nervous system associated with various viral infections including HIV infection. We present the findings of seven HIV-infected patients with mild to moderate immunosuppression presenting with atypical features. Four patients had a multiphasic course; three patients had tumefactive lesions, and two patients had corpus callosum lesions. Two patients with the multiphasic course also had tumefactive lesions. Their clinical and radiological findings are presented. Despite the few cases, we propose that the dysimmune process lying between marked immunosuppression (CD4 < 200 cells/MUL) and normal CD4 counts (CD4 > 500 cells/MUL) might be responsible for these atypical presentations. PMID- 27687127 TI - The role of background diet on the effects of eicosapentaenoic acid and docosahexaenoic acid supplementation in healthy pre-menopausal women: a randomized, cross-over, controlled study. AB - BACKGROUND: The links between dietary fat intake, polyunsaturated fatty acid intake and breast cancer risk remain equivocal, with some studies pointing to improvements in risk upon omega-3 supplementation. However, the background diet is poorly controlled in most studies, potentially confounding this link. Therefore, this study examined the hypothesis that in order to see the benefits of omega-3 fatty acid supplementation, the background diet must be low in fat. METHODS: Of the 56 healthy, pre-menopausal women randomized to one of two experimental arms, consisting of a two-treatment, randomized, cross-over design, 41 completed the 10 month intervention. The two diet phases (habitual and low fat) were separated by a washout phase, each lasting 3 menstrual cycles. During each diet phase, women were supplemented with 1.2 g eicosapentaenoic acid + docosahexaenoic acid per day. RESULTS: Red blood cell fatty acid composition indicated that more eicosapentaenoic acid and docosahexaenoic acid was incorporated in the low-fat diet than the habitual diet, though both diet phases resulted in significant increases in the omega-3 to omega-6 ratio. In the context of omega-3 supplementation in breast cancer risk reduction, we also measured fatty acid incorporation into nipple aspirate fluid. Similar changes to red blood cells were noted in nipple aspirate fluid, with higher incorporation of eicosapentaenoic acid in the low-fat diet phase. CONCLUSIONS: These data suggest that the total level of dietary fat has some direct impact on fatty acid partitioning in addition to the recognized importance of fatty acid ratios, and supports the hypothesis that dietary fat intake must be considered a confounder in supplementation trials. Additionally, we demonstrate that n3 supplementation both reaches and imparts improvements in lipid content and n3:n6 at the target breast tissue.

AB - INTRODUCTION: The majority of allergic subjects are polysensitized. In Europe, allergy immunotherapy (AIT) in these patients is usually limited to their single clinically most troublesome allergy while in the U.S. the immunotherapy prescription usually includes all allergen extracts to which the patient has evidence of clinical sensitivity. Areas covered: This article will review the evidence supporting the U.S. practice. It will also review the major new development in the management of polysensitized patients, the introduction of component-resolved diagnosis (CRD). Expert commentary: This allows, in many cases, distinguishing in polysensitized patients between sensitization to the major allergens of several unrelated allergen extracts and to panallergens that cause broad patterns of cross-reactivity. PMID- 27687125 TI - Electroacupuncture in conscious free-moving mice reduces pain by ameliorating peripheral and central nociceptive mechanisms. AB - Integrative approaches such as electroacupuncture, devoid of drug effects are gaining prominence for treating pain. Understanding the mechanisms of electroacupuncture induced analgesia would benefit chronic pain conditions such as sickle cell disease (SCD), for which patients may require opioid analgesics throughout life. Mouse models are instructive in developing a mechanistic understanding of pain, but the anesthesia/restraint required to administer electroacupuncture may alter the underlying mechanisms. To overcome these limitations, we developed a method to perform electroacupuncture in conscious, freely moving, unrestrained mice. Using this technique we demonstrate a significant analgesic effect in transgenic mouse models of SCD and cancer as well as complete Freund's adjuvant-induced pain. We demonstrate a comprehensive antinociceptive effect on mechanical, cold and deep tissue hyperalagesia in both genders. Interestingly, individual mice showed a variable response to electroacupuncture, categorized into high-, moderate-, and non-responders. Mechanistically, electroacupuncture significantly ameliorated inflammatory and nociceptive mediators both peripherally and centrally in sickle mice correlative to the antinociceptive response. Application of sub-optimal doses of morphine in electroacupuncture-treated moderate-responders produced equivalent antinociception as obtained in high-responders. Electroacupuncture in conscious freely moving mice offers an effective approach to develop a mechanism-based understanding of analgesia devoid of the influence of anesthetics or restraints.

PMID- 27687129 TI - Flux of signalling endosomes undergoing axonal retrograde transport is encoded by presynaptic activity and TrkB. AB - Axonal retrograde transport of signalling endosomes from the nerve terminal to the soma underpins survival. As each signalling endosome carries a quantal amount of activated receptors, we hypothesized that it is the frequency of endosomes reaching the soma that determines the scale of the trophic signal. Here we show that upregulating synaptic activity markedly increased the flux of plasma membrane-derived retrograde endosomes (labelled using cholera toxin subunit-B: CTB) in hippocampal neurons cultured in microfluidic devices, and live Drosophila larval motor neurons. Electron and super-resolution microscopy analyses revealed that the fast-moving sub-diffraction-limited CTB carriers contained the TrkB neurotrophin receptor, transiently activated by synaptic activity in a BDNF independent manner. Pharmacological and genetic inhibition of TrkB activation selectively prevented the coupling between synaptic activity and the retrograde flux of signalling endosomes. TrkB activity therefore controls the encoding of synaptic activity experienced by nerve terminals, digitalized as the flux of retrogradely transported signalling endosomes. PMID- 27687130 TI - Differential roles of NF-Y transcription factor in ER chaperone expression and neuronal maintenance in the CNS. AB - The mammalian central nervous system (CNS) contains various types of neurons with different neuronal functions. In contrast to established roles of cell type specific transcription factors on neuronal specification and maintenance, whether ubiquitous transcription factors have conserved or differential neuronal function remains uncertain. Here, we revealed that inactivation of a ubiquitous factor NF Y in different sets of neurons resulted in cell type-specific neuropathologies and gene downregulation in mouse CNS. In striatal and cerebellar neurons, NF-Y inactivation led to ubiquitin/p62 pathologies with downregulation of an endoplasmic reticulum (ER) chaperone Grp94, as we previously observed by NF-Y deletion in cortical neurons. In contrast, NF-Y inactivation in motor neurons induced neuronal loss without obvious protein deposition. Detailed analysis clarified downregulation of another ER chaperone Grp78 in addition to Grp94 in motor neurons, and knockdown of both ER chaperones in motor neurons recapitulated the pathology observed after NF-Y inactivation. Finally, additional downregulation of Grp78 in striatal neurons suppressed ubiquitin accumulation induced by NF-Y inactivation, implying that selective ER chaperone downregulation mediates different neuropathologies. Our data suggest distinct roles of NF-Y in protein homeostasis and neuronal maintenance in the CNS by differential regulation of ER chaperone expression.

AB - Neurofibrillary tangles composed of aggregates of hyperphosphorylated tau proteins are one of the neuropathological hallmarks of Alzheimer's disease (AD) in addition to the deposition of beta-amyloid plaques. Since the deposition of tau aggregates is closely associated with the severity of AD, the in vivo detection of tau aggregates may be useful as a biomarker for the diagnosis and progression of AD. In this study, we designed and synthesized a new series of radioiodinated benzoimidazopyridine (BIP) derivatives, and evaluated their utility as single photon emission computed tomography (SPECT) imaging agents targeting tau aggregates in AD brains. Five radioiodinated BIP derivatives were successfully prepared in high radiochemical yields and purities. In in vitro autoradiographic studies using postmortem AD brains, all BIP derivatives displayed high accumulation of radioactivity in the brain sections with abundant neurofibrillary tangles, while no marked radioactivity accumulation was observed in the brain sections with only beta-amyloid aggregates, indicating that the BIP derivatives exhibited selective binding to tau aggregates. Biodistribution studies in normal mice showed high brain uptake at 2 min postinjection (3.5-4.7% ID/g) and rapid clearance at 60 min postinjection (0.04-0.23% ID/g), which is highly desirable for tau imaging agents. The results of the present study suggest that [123I]BIP derivatives may be useful SPECT agents for the in vivo imaging of tau aggregates in AD.

PMID- 27687139 TI - Inhibitory actions of selected natural substances on formation of advanced glycation endproducts and advanced oxidation protein products. AB - BACKGROUND: Advanced glycation endproducts (AGE) and advanced oxidation protein products (AOPP) arise as a result of excessive glycation and oxidation processes of proteins in hyperglycemia and oxidative stress conditions respectively, both in vivo and in vitro. In vivo these processes are especially intensified in patients with diabetes, and the adverse effects of AGE and AOPP are particularly unfavorable for the pathogenesis and aggravate the biochemical disturbances and clinical complications of diabetes. Total AGE and AOPP (T-AGE and T-AOPP) are heterogeneous groups of compounds, and they can be divided into two main fractions: high- and low-molecular-weight, i.e. HMW-AGE and HMW-AOPP as well as LMW-AGE and LMW-AOPP. Therefore it is important to find natural substances that will prevent formation of total AGE and AOPP and their high- and low-molecular weight fractions and thereby reduce their adverse effects on tissues and organs. METHOD: Selected natural substances and dietary supplements such as vitamin C, aminoguanidine, quercetin and green tea as well as the multicompound formulations Padma Circosan and Padma 28 were tested in an in vitro model using bovine serum albumin (BSA). Fluorescence of T-, HMW- and LMW-AGE and concentration of T-, HMW- and LMW-AOPP were measured after incubation with these substances. RESULTS: In the examined concentrations quercetin showed the greatest degree of inhibition for T-AGE (60.5 %) as well as for HMW-AGE (79.5 %), while in the case of LMW-AGE the greatest degree of glycation inhibition was shown by Padma Circosan (74.9 %). T-AOPP and HMW-AOPP were best inhibited by vitamin C (87.3 and 89.1 % respectively). The results obtained for LMW-AOPP are atypical, but the lowest concentration was observed in a sample with Padma 28. CONCLUSION: The results show that all tested natural compounds have inhibitory activity towards the formation of total and low- and high-molecular-weight forms of AGE and AOPP in vitro. That suggest a possible role in the prevention of diabetic complications, especially the multiherbal compound Padma preparations, which are especially effective in lowering the most dangerous, i.e. LMW fractions.

On presentation to our emergency department, the patient's complaints were solemnly intermittent pain and occasional swelling of his proximal lower leg. Deep vein thrombosis, compartment syndrome, and implant dislocation were ruled out, and the patient was discharged after his symptoms improved without further intervention. Four weeks later, the patient was readmitted for similar symptoms. A computed tomography (CT) angiography then revealed a pseudoaneurysm of the anterior tibial artery at the level of the proximal interlocking screw insertion. Aneurysmal sac excision with vessel repair was performed while reconstructing the additional dislocated proximal fibular fracture using standard AO/ASIF plating. Postoperatively, sufficient flow through the repaired vessel was documented using Doppler ultrasound and CT angiography. However, the patient sustained a temporal damage to the peroneal nerve after surgery. This case highlights the risk of a pseudoaneurysm of the anterior tibial artery after interlocking screw insertion as a rare but major complication of a routine surgical procedure. Early ultrasound diagnostics, CT angiography, or magnetic resonance (MR) angiogram should be performed to prevent the delay in diagnosis and treatment of such complications.

AB - Polycrystalline bis(dialkyldithiophosphato)Pt(II) complexes of the form [Pt{S2P(OR)2}2] (R = ethyl, iso-propyl, iso-butyl, sec-butyl or cyclo-hexyl group) were studied using solid-state 31P and 195Pt NMR spectroscopy, to determine the influence of R to the structure of the central chromophore. The measured anisotropic chemical shift (CS) parameters for 31P and 195Pt afford more detailed chemical and structural information, as compared to isotropic CS and J couplings alone. Advanced theoretical modeling at the hybrid DFT level, including both crystal lattice and the important relativistic spin-orbit effects qualitatively reproduced the measured CS tensors, supported the experimental analysis, and provided extensive orientational information. A particular correction model for the non-negligible lattice effects was adopted, allowing one to avoid a severe deterioration of the 195Pt anisotropic parameters due to the high requirements posed on the pseudopotential quality in such calculations. Though negligible differences were found between the 195Pt CS tensors with different substituents R, the 31P CS parameters differed significantly between the complexes, implying the potential to distinguish between them. The presented approach enables good resolution and a detailed analysis of heavy-element compounds by solid-state NMR, thus widening the understanding of such systems.

AB - OBJECTIVES: The management of neonatal post-haemorrhagic hydrocephalus (nPHH) varies considerably between centres and even between neurosurgeons in the same centre. We performed a nationwide survey to evaluate current practice in the UK and reviewed the evidence for each intervention. METHODS: An online semi structured questionnaire was emailed to all units registered on the British Paediatric Neurosurgery Group Mailing List. The survey consisted of 18 questions designed to establish the status quo in the management of nPHH, including preferred temporising procedure, factors guiding the timing of intervention and willingness to participate in a prospective study. RESULTS: A total of 24 consultants responded to the survey. Ventricular access device (VAD), trans fontanelle tap, ventriculosubgaleal shunt (VSGS) and lumbar puncture (LP) were used by 33, 25, 17 and 17%, respectively, as the first temporising measure. Almost all reported that the timing of this intervention was guided by increasing head circumference and tense fontanelle. If the first temporising procedure fails, VAD, external ventricular drainage (EVD), trans-fontanelle tap, VSGS and other procedures (including ventriculoperitoneal (VP) shunting and endoscopic third ventriculostomy (ETV)) were performed by 42, 17, 13, 8 and 21%, respectively. Almost all respondents reported that VP shunting would be their preferred method of definitive cerebrospinal fluid (CSF) diversion. Almost all responded that they would be willing to participate in a prospective study in the future to determine best practice. CONCLUSION: As expected there was a significant heterogeneity between respondents in the initial management of nPHH in the UK. VAD was the most popular first and second choice temporising measure. On reviewing the literature, it is clear that more work still needs to be done to establish which temporising measure is best. There is willingness in the UK to participate in a study to help determine this. PMID- 27687146 TI - On the maintenance of genetic variation and adaptation to environmental change: considerations from population genomics in fishes. AB - The first goal of this paper was to overview modern approaches to local adaptation, with a focus on the use of population genomics data to detect signals of natural selection in fishes. Several mechanisms are discussed that may enhance the maintenance of genetic variation and evolutionary potential, which have been overlooked and should be considered in future theoretical development and predictive models: the prevalence of soft sweeps, polygenic basis of adaptation, balancing selection and transient polymorphisms, parallel evolution, as well as epigenetic variation. Research on fish population genomics has provided ample evidence for local adaptation at the genome level. Pervasive adaptive evolution, however, seems to almost never involve the fixation of beneficial alleles. Instead, adaptation apparently proceeds most commonly by soft sweeps entailing shifts in frequencies of alleles being shared between differentially adapted populations. One obvious factor contributing to the maintenance of standing genetic variation in the face of selective pressures is that adaptive phenotypic traits are most often highly polygenic, and consequently the response to selection should derive mostly from allelic co-variances among causative loci rather than pronounced allele frequency changes. Balancing selection in its various forms may also play an important role in maintaining adaptive genetic variation and the evolutionary potential of species to cope with environmental change. A large body of literature on fishes also shows that repeated evolution of adaptive phenotypes is a ubiquitous evolutionary phenomenon that seems to occur most often via different genetic solutions, further adding to the potential options of species to cope with a changing environment. Moreover, a paradox is emerging from recent fish studies whereby populations of highly reduced effective population sizes and impoverished genetic diversity can apparently retain their adaptive potential in some circumstances. Although more empirical support is needed, several recent studies suggest that epigenetic variation could account for this apparent paradox. Therefore, epigenetic variation should be fully integrated with considerations pertaining to role of soft sweeps, polygenic and balancing selection, as well as repeated adaptation involving different genetic basis towards improving models predicting the evolutionary potential of species to cope with a changing world.

AB - INTRODUCTION: Successful global treatment as prevention (TasP) requires identifying HIV-positive individuals at high risk for transmitting HIV, and having impact via potential infections averted. This study estimated the frequency and predictors of numbers of HIV transmissions and bacterial sexually transmitted infection (STI) acquisition among sexually active HIV-positive individuals in care from three representative global settings. METHODS: HIV positive individuals (n=749), including heterosexual men, heterosexual women and men who have sex with men (MSM) in HIV care, were recruited from Chiang Mai (Thailand), Rio De Janeiro (Brazil) and Lusaka (Zambia). Participants were assessed on HIV and STI sexual transmission risk variables, psychosocial characteristics and bacterial STIs at enrolment and quarterly for 12 months (covering 15 months). Estimated numbers of HIV transmissions per person were calculated using reported numbers of partners and sex acts together with estimates of HIV transmissibility, accounting for ART treatment and condom use. RESULTS: An estimated 3.81 (standard error, (SE)=0.63) HIV transmissions occurred for every 100 participants over the 15 months, which decreased over time. The highest rate was 19.50 (SE=1.68) for every 100 MSM in Brazil. In a multivariable model, country*risk group interactions emerged: in Brazil, MSM had 2.85 (95% CI=1.45, 4.25, p<0.0001) more estimated transmissions than heterosexual men and 3.37 (95% CI=2.01, 4.74, p<0.0001) more than heterosexual women over the 15 months. For MSM and heterosexual women, the combined 12-month STI incidence rate for the sample was 22.4% (95% CI=18.1%, 27.3%; incidence deemed negligible in heterosexual men). In the multivariable model, MSM had 12.3 times greater odds (95% CI=4.44, 33.98) of acquiring an STI than women, but this was not significant in Brazil. Higher alcohol use on the Alcohol Use Disorders Identification Test (OR=1.04, 95% CI=1.01, 1.08) was also significantly associated with increased STI incidence. In bivariate models for both HIV transmissions and STI incidence, higher depressive symptoms were significant predictors. CONCLUSIONS: These data help to estimate the potential number of HIV infections transmitted and bacterial STIs acquired over time in patients established in care, a group typically considered at lower transmission risk, and found substantial numbers of estimated HIV transmissions. These findings provide an approach for evaluating the impact (in phase 2 studies) and potentially cost-effectiveness of global TasP efforts. PMID- 27687147 TI - Does age matter? Comparison of neurobehavioral effects of paraquat exposure on postnatal and adult C57BL/6 mice. AB - Epidemiological studies have revealed that environmentally relevant low levels of paraquat (PQ) exposure is listed on the etiology of neurological disorders such as Parkinson's disease (PD). The behavioral effects of PQ are of current interest, especially when exposure occurs in the period of early stage of life. To characterize whether and how age affects neurobehavioral performances of mice after PQ exposure, 21 days postnatal (PN21) and adult male C57BL/6 mice were daily administrated by oral gavage with 0 mg/kg (saline, control), 5 mg/kg or 10 mg/kg of PQ for 28 consecutive days. Survival rate and body weight were analyzed. Subsequently, mice were subjected to Morris water maze tests (MWM). The results showed that mice exposed to PQ had significantly longer latencies than those in the control group, with a dose-dependent manner. Furthermore, PN21 mice tended to have longer latencies than adult mice in the same dose group. Our data suggested that PQ exposure induced significant learning and memory impairment and more severely in PN21 mice when compared with adult mice.

AB - Microglia can aggravate olfactory dysfunction by mediating neuronal death in the olfactory bulb (OB) of a murine model of Niemann-Pick disease type C1 (NPC1), a fatal neurodegenerative disorder accompanied by lipid trafficking defects. In this study, we focused on the crosstalk between neurons and microglia to elucidate the mechanisms underlying extensive microgliosis in the NPC1-affected brain. Microglia in the OB of NPC1 mice strongly expressed CX3C chemokine receptor 1 (Cx3cr1), a specific receptor for the neural chemokine C-X3-C motif ligand 1 (Cx3cl1). In addition, a high level of Cx3cl1 was detected in NPC1 mouse derived CSF due to enhanced catalytic activity of Cathepsin S (Ctss), which is responsible for Cx3cl1 secretion. Notably, nasal delivery of Cx3cl1 neutralizing antibody or Ctss inhibitor could inhibit the Cx3cl1-Cx3cr1 interaction and support neuronal survival through the suppression of microglial activation, leading to an improvement in the olfactory function in NPC1 mice. Relevant in vitro experiments revealed that intracellular cholesterol accumulation could act as a strong inducer of abnormal Ctss activation and, in turn, stimulated the Cx3cl1-Cx3cr1 axis in microglia via p38 mitogen-activated protein kinase signaling. Our data address the significance of Cx3cl1-Cx3cr1 interaction in the development of microglial neurotoxicity and suggest that Ctss is a key upstream regulator. Therefore, this study contributes to a better understanding of the crosstalk between neurons and microglia in the development of the neurodegeneration and provides a new perspective for the management of olfactory deficits and other microglia-dependent neuropathies.

AB - The present study examined the relationships between work-related characteristics in internships, psychological needs satisfaction, motivation and mental health using a partial least squares path modeling. Midwifery students (N = 214; Mage = 22.8 years) from three French schools completed different questionnaires online. Results showed (1) the importance of work resources (work control and social support) as protective factors of psychological needs satisfaction; and (2) the role of competence need satisfaction through motivation in the relationships between work resources and mental health. Midwifery schools should pay more attention to these two results, and take them into account in midwifery students' training. PMID- 27687150 TI - Structural and functional quantitative susceptibility mapping from standard fMRI studies. AB - Standard functional MRI (fMRI), which includes resting-state or paradigm-driven designs, is widely used in studies of brain function, aging, and disease. These fMRI studies typically use two-dimensional gradient echo-planar imaging, which inherently contains phase data that enables quantitative susceptibility mapping (QSM). This work focuses on the dual value of QSM within fMRI studies, by providing both a localized analysis of functional changes in activated tissue, and iron-sensitive structural maps in deep grey matter (DGM). Using a visual paradigm fMRI study on healthy volunteers at clinical (1.5 T) and high field strength (4.7 T), we perform functional analysis of magnitude and QSM time series, and at the same time harness structural QSM of iron-rich DGM, including globus pallidus, putamen, caudate head, substantia nigra, and red nucleus. The effects of fMRI spatial resolution and time series variation on structural DGM QSM are investigated. Our results indicate that structural DGM QSM is feasible within existing fMRI studies, provided that the voxel dimensions are equal to or less than 3 mm, with higher resolutions preferred. The mean DGM QSM values were about 40 to 220 ppb, while the interquartile ranges of the DGM QSM time series varied from about 3 to 9 ppb, depending on structure and resolution. In contrast, the peak voxel functional QSM (fQSM) changes in activated visual cortex ranged from about -10 to -30 ppb, and functional clusters were consistently smaller on QSM than magnitude fMRI. Mean-level DGM QSM of the time series was successfully extracted in all cases, while fQSM results were more prone to residual background fields and showed less functional change compared with standard magnitude fMRI. Under the conditions prescribed, standard fMRI studies may be used for robust mean-level DGM QSM, enabling study of DGM iron accumulation, in addition to functional analysis.

PMID- 27687151 TI - Exploring gender perceptions of risk of HIV infection and related behaviour among elderly men and women of Ga-Rankuwa, Gauteng Province, South Africa. AB - The literature shows that there are important differences between women and men in the underlying mechanisms of transmission of HIV infection and AIDS, as well as in the social and economic consequences of HIV/AIDS. These stem from sexual behaviour and socially constructed 'gender' differences between women and men in roles and responsibilities. Despite the fact that numerous gender-related sociocultural factors influence HIV/AIDS protective behaviours, little gender specificity is included in HIV prevention among the elderly. In order to close this gap, this study explored gender-related perceptions of risk of HIV infection among elderly men and women of Ga-Rankuwa in Gauteng Province, South Africa. This qualitative study used purposive sampling to conduct three focus group interviews with 22 women and 10 men who were above 60 years of age. Findings revealed that both genders blame each other for the spreading of HIV/AIDS. Male participants displayed the tendency to have multiple partners, whereas females accepted that males are promiscuous. Mixed perceptions about disclosure of HIV status were found. Condom use was a challenge, as men did not know how to introduce it with their wives, and some female participants indicated that men are resistant to using condoms. The elderly men also believed that women will have sex in exchange for money. It is concluded that there is a need for substantial behaviour change among both elderly males and females, which should address gender power relations. More in-depth and extensive research in this area is recommended. PMID- 27687152 TI - Qualitative evaluation of selected social factors that impact sexual risk-taking behaviour among African students in Kwazulu-Natal, South Africa. AB - BACKGROUND: The incidence of HIV and AIDS continues to be a source of great concern within universities in South Africa. Furthermore, university students constitute an important community in the intervention against the HIV/AIDS epidemic. Students in the age group of 15-24 years are at a greater risk of HIV infection than any other group in the country; yet, little is known about why they continue to engage in risky sexual practices. OBJECTIVES: This study was designed to explore the sexual behaviour of students in a metropolitan Durban University of Technology in KwaZulu-Natal to understand the social factors underlying their risk of HIV infection. METHODS: This is a qualitative study that used cluster sampling where the population was stratified by campus and faculty. The study population was selected using a standard randomization technique. This was a part of a multi-phased research project aimed at providing a sero prevalence baseline and an analysis of risk-taking behaviour at a Durban University of Technology in the eThekwini Metropolitan Municipality area. RESULTS: The study highlights peer pressure among students as an influence in promoting high-risk sexual behaviour. Within this context, the findings revealed that university students lack the ability to negotiate risk-aware decisions especially regarding sexual relationships. CONCLUSION: This study draws attention to the perspectives of African university students regarding their risk-taking sexual practices and selected factors which influence such behaviour. The findings are not exhaustive in exploring contextual antecedents that shape students' sexual practices. However, they provide an important basis in understanding key factors which expose students to HIV infections. The study provides insights into opportunities for further studies as well as preventative implications. PMID- 27687153 TI - Food insecurity among students living with HIV: Strengthening safety nets at the Nelson Mandela Metropolitan University, South Africa. AB - The HIV prevalence in South Africa among students at higher education institutions (HEIs) in 2008 was reported to be 3.4%, with the highest HIV prevalence found in the Eastern Cape Province. Students at these facilities are also increasingly affected by socio-economic constraints that may impact on food security. Little is known about the impact of food insecurity on HIV-infected students in HEIs in South Africa. The purpose of this paper is to describe food insecurity and the nutritional status among HIV-infected students on the Nelson Mandela Metropolitan University campuses in South Africa, as well as current initiatives to strengthen the safety nets for food-insecure students. This descriptive, cross-sectional survey was conducted among a convenience sample of known HIV-infected, registered students (n = 63), older than 18 years of age and managed as part of the Campus Health Service antiretroviral therapy (ART) programme. Ethical approval for the study was obtained from the Research Ethics Committee (NMMU) and participants were included in the sample after providing written, informed consent. Findings indicate that food insecurity was common with more than 60% of the sample reporting food insecurity at the household level during the previous month. Of the sample, 51% were classified as being either overweight or obese. Although food insecurity did not contribute to weight loss in our sample, food-insecure students were more likely to consume inadequate amounts of vitamins and minerals, especially antioxidants that are important in supporting the immune system. Food insecurity has been identified as affecting the majority of HIV-infected students in this study, especially regarding their difficulty in accessing nutritious foods. As overweight and obesity also seem to threaten the health and future well-being of the students, appropriate management of the overweight individuals and those with obesity should be instituted in order to prevent the development of chronic diseases of lifestyle, thus allowing for a healthier more productive life. Current intervention strategies to strengthen food security have made inroads to improve access to healthier food options. PMID- 27687154 TI - Beliefs and implementation of evidence-based practice among nurses and allied healthcare providers in the Valais hospital, Switzerland. AB - RATIONALE: Evidence-based practice (EBP) is upheld as a means for patients to receive the most efficient care in a given context. Despite the available evidence and positive beliefs about it, implementing EBP as standard daily practice still faces many obstacles. AIMS AND OBJECTIVES: This study investigated the beliefs about and implementation of EBP among nurses and allied healthcare providers (AHP) in 9 acute care hospitals in the canton of Valais, Switzerland. MATERIALS AND METHODS: A cross-sectional descriptive survey was conducted. The target population was composed of 1899 nurses and 126 AHPs. Beliefs about and implementation of EBP were measured using EBP-Beliefs and EBP-Implementation scales of Melnyk et al. RESULTS: The initial sample consisted in 491 participants (overall response rate 24.2%): 421 nurses (22.4% response rate) and 78 AHPs (61.9% response rate). The final sample, composed only of those who declared previous exposure to EBP, included 391 participants (329 nurses and 62 AHPs). Overall, participants had positive attitudes towards EBP and were willing to increase their knowledge to guide practice. However, they acknowledged poor implementation of EBP in daily practice. A significantly higher level of EBP implementation was declared by those formally trained in it (P = 0.006) and by those occupying more senior professional functions (P = 0.004). EBP-Belief scores predicted 13% of the variance in the EBP-Implementation scores (R2 = 0.13). DISCUSSION: EBP is poorly implemented despite positive beliefs about it. Continuing education and support on EBP would help to ensure that patients receive the best available care based on high-quality evidence, patient needs, clinical expertise, and a fair distribution of healthcare resources. CONCLUSION: This study's results will be used to guide institutional strategy to increase the use of EBP in daily practice. PMID- 27687155 TI - Ligand-dependent ribozymes. AB - The discovery of catalytic RNA (ribozymes) more than 30 years ago significantly widened the horizon of RNA-based functions in natural systems. Similarly to the activity of protein enzymes that are often modulated by the presence of an interaction partner, some examples of naturally occurring ribozymes are influenced by ligands that can either act as cofactors or allosteric modulators. Recent discoveries of new and widespread ribozyme motifs in many different genetic contexts point toward the existence of further ligand-dependent RNA catalysts. In addition to the presence of ligand-dependent ribozymes in nature, researchers have engineered ligand dependency into natural and artificial ribozymes. Because RNA functions can often be assembled in a truly modular way, many different systems have been obtained utilizing different ligand-sensing domains and ribozyme activities in diverse applications. We summarize the occurrence of ligand-dependent ribozymes in nature and the many examples realized by researchers that engineered ligand-dependent catalytic RNA motifs. We will also highlight methods for obtaining ligand dependency as well as discuss the many interesting applications of ligand-controlled catalytic RNAs.

PMID- 27687156 TI - Measuring the representational space of music with fMRI: a case study with Sting. AB - Functional brain imaging has revealed much about the neuroanatomical substrates of higher cognition, including music, language, learning, and memory. The technique lends itself to studying of groups of individuals. In contrast, the nature of expert performance is typically studied through the examination of exceptional individuals using behavioral case studies and retrospective biography. Here, we combined fMRI and the study of an individual who is a world class expert musician and composer in order to better understand the neural underpinnings of his music perception and cognition, in particular, his mental representations for music. We used state of the art multivoxel pattern analysis (MVPA) and representational dissimilarity analysis (RDA) in a fixed set of brain regions to test three exploratory hypotheses with the musician Sting: (1) Composing would recruit neutral structures that are both unique and distinguishable from other creative acts, such as composing prose or visual art; (2) listening and imagining music would recruit similar neural regions, indicating that musical memory shares anatomical substrates with music listening; (3) the MVPA and RDA results would help us to map the representational space for music, revealing which musical pieces and genres are perceived to be similar in the musician's mental models for music. Our hypotheses were confirmed. The act of composing, and even of imagining elements of the composed piece separately, such as melody and rhythm, activated a similar cluster of brain regions, and were distinct from prose and visual art. Listened and imagined music showed high similarity, and in addition, notable similarity/dissimilarity patterns emerged among the various pieces used as stimuli: Muzak and Top 100/Pop songs were far from all other musical styles in Mahalanobis distance (Euclidean representational space), whereas jazz, R&B, tango and rock were comparatively close. Closer inspection revealed principaled explanations for the similarity clusters found, based on key, tempo, motif, and orchestration. PMID- 27687158 TI - Concordance between cardio-protective effect on isoproterenol-induced acute myocardial ischemia and phenolic content of different extracts of Curcuma aromatica. AB - CONTEXT: A classic traditional Chinese medicine Curcuma aromatica Salisb. (Zingiberaceae) has been reported to have favourable effects on the cardiovascular system. OBJECTIVE: To research the cardio-protective effect of different C. aromatica hydroalcoholic extracts on isoproterenol (ISO)-induced acute myocardial ischemia (AMI) in rats. The total phenols in different extracts were detected simultaneously. MATERIALS AND METHODS: The rhizomes of C. aromatica dry powder were refluxed with 30%, 50%, 70% and 90% hydroalcoholic solvents to obtain different extracts. Rats were pretreated with four C. aromatica extracts (150 mg/kg/day, i.g.) for 9 days and then given ISO (30 mg/kg/day, s.c.) for 2 consecutive days, respectively. Heart rate, ST-segment, T-wave and serum levels of CK-MB, LDH, TAC, SOD, NO and MDA were measured. Total phenols of the different extracts were determined using the Folin-Ciocalteu assay. RESULTS: Pretreatment with C. aromatica significantly decreased the elevated levels of serum specific cardiac injury biomarkers (CK-MB and LDH), the serum level of MDA, the ST-segment and T-wave. In addition, C. aromatica increased the heart rate, as well as the levels of TAC, SOD and NO, compared to ISO-induced controls. The total phenols in the 70% extract were higher than in the other extracts reaching 5.629 +/- 0.037 mg/g, crude drug. DISCUSSION AND CONCLUSION: Curcuma aromatica hydroalcoholic extracts exhibited remarkable cardio-protective effects against AMI in rats. The 70% extracts showed the strongest bioactivity. These results indicate that ethanol concentration in preparation of extracts of C. aromatica plays an important role in the protective effect against AMI. PMID- 27687157 TI - Comparison of antibiotic regimens in preterm premature rupture of membranes: neonatal morbidity and 2-year follow-up of neurologic outcome. AB - OBJECTIVES: The objective of this study was to compare neonatal morbidity and neurologic outcome at 2 years between groups treated with antibiotics regimens consisting clarithromycin and erythromycin in preterm premature rupture of the membranes (pPROM) patients delivered before 32 weeks of gestation. METHODS: This was a retrospective study comparing neonatal morbidity as primary outcome measures and the neurological outcome at 2 years as secondary outcome. RESULTS: A total of 166 women were included: 80 treated with erythromycin and 86 treated with clarithromycin. The median gestational age at delivery was greater in clarithromycin group (p = 0.005). There was no significant difference in latency (p = 0.77). The incidence of histological chorioamnionitis was significantly lower in clarithromycin group (p = 0.004). By multivariable analysis adjusting confounding variables, the incidence of bronchopulmonary dysplasia and intraventricular hemorrhage (>=Grade 3) was lower in clarithromycin group (BPD; OR 0.34, 95% CI [0.13-0.90]), IVH; OR 0.23, 95% CI [0.06-0.91], respectively). Other morbidities and neurologic outcome at 2 years' corrected age showed no statistically significant difference between two groups. CONCLUSION: We suggest that clarithromycin-based regimen may be worth considering as an alternative choice of erythromycin in pPROM patients.

AB - South African pig sector is a contributor to the agricultural industry. A study was conducted to identify the production constraints and compare the management practices in smallholder pig farms in Mpumalanga, South Africa. A total of 220 selected smallholder pig farmers were interviewed. Smallholder pig farming was predominated by male (64 %), age above 50 years (54 %), black Africans (98.6 %), and three quarters of the smallholder farmers were poor to just below average. Majority (80 %) have no pig husbandry training, while only 33 % received assistance from government's Agricultural Department. In terms of stock, mixed breeds (89 %) from exotic pigs were mostly kept and majority (87 %) of the farmers kept <=10 sows in their herds. Many farmers (75 %) engaged in risky behavior of buying auctioned-sourced boars, free-range boars, and untested boars from neighbors and relatives. Few (17 %) farmers practiced vaccination and only 10 % kept farm records. Majority of the responses on pre-weaning mortality (50 %) and post-weaning mortality (90 %) were within acceptable range of 1-10 and 1-5 % mortality rates, respectively. The lead causes of mortality were weak piglets and crushing (46 %), diarrhea (27 %), poor management knowledge (19 %), and malnutrition (16 %). Agricultural training and government incentives will facilitate improved productivity in smallholder pig farming. PMID- 27687161 TI - The chondroitin sulfate/dermatan sulfate 4-O-endosulfatase from marine bacterium Vibrio sp FC509 is a dimeric species: Biophysical characterization of an endosulfatase. AB - Sulfatases catalyze hydrolysis of sulfate groups. They have a key role in regulating the sulfation states that determine the function of several scaffold molecules. Currently, there are no studies of the conformational stability of endosulfatases. In this work, we describe the structural features and conformational stability of a 4-O-endosulfatase (EndoV) from a marine bacterium, which removes specifically the 4-O-sulfate from chondroitin sulfate/dermatan sulfate. For that purpose, we have used several biophysical techniques, namely, fluorescence, circular dichroism (CD), FTIR spectroscopy, analytical ultracentrifugation (AUC), differential scanning calorimetry (DSC), mass spectrometry (MS), dynamic light scattering (DLS) and size exclusion chromatography (SEC). The protein was a dimer with an elongated shape. EndoV acquired a native-like structure in a narrow pH range (7.0-9.0); it is within this range where the protein shows the maximum of enzymatic activity. The dimerization did not involve the presence of disulphide-bridges as suggested by AUC, SEC and DLS experiments in the presence of beta-mercaptoethanol (beta-ME). EndoV secondary structure is formed by a mixture of alpha and beta-sheet topology, as judged by deconvolution of CD and FTIR spectra. Thermal and chemical denaturations showed irreversibility and the former indicates that protein did not unfold completely during heating. PMID- 27687162 TI - Biophysical dissection of schistosome septins: Insights into oligomerization and membrane binding. AB - Septins are GTP-binding proteins that are highly conserved among eukaryotes and which are usually membrane-associated. They have been linked to several critical cellular functions such as exocytosis and ciliogenesis, but little mechanistic detail is known. Their assembly into filaments and membrane binding properties are incompletely understood and that is specially so for non-human septins where such information would offer therapeutic potential. In this study we use Schistosoma mansoni, exhibiting just four septin genes, as a simpler model for characterizing the septin structure and organization. We show that the biochemical and biophysical proprieties of its SmSEPT5 and SmSEPT10 septins are consistent with their human counterparts of subgroups SEPT2 and SEPT6, respectively. By succeeding to isolate stable constructs comprising distinct domains of SmSEPT5 and SmSEPT10 we were able to infer the influence of terminal interfaces in the oligomerization and membrane binding properties. For example, both proteins tended to form oligomers interacting by the N- and C-terminal interfaces in a nucleotide independent fashion but form heterodimers via the G interface, which are nucleotide dependent. Furthermore, we report for the first time that it is the C-terminus of SmSETP10, rather than the N-terminal polybasic region found in other septins, that mediates its binding to liposomes. Upon binding we observe formation of discrete lipo-protein clusters and higher order septin structures, making our system an exciting model to study interactions of septins with biological membranes. PMID- 27687163 TI - Embracing an "African Ethos" to facilitate African immigrants participation in medical genetics and genomics research. AB - BACKGROUND: Limited published research exists on perceptions and potentials for black African immigrants' participation in medical genetics and genomics research. PURPOSE: This study explores the inclination and disinclination of African immigrants to be involved in genetics and genomics research. METHODS: In depth qualitative interviews were employed in which a sample of black African immigrants 18 years and older (n = 34) were interviewed. DISCUSSION: Barriers included contrary beliefs and customs about disease and the human body that differs from Western conceptions, and lack of genuine connection to the health care system. Facilitators included promotion of an "African ethos," wherein Africans unite with one another in a communal extension of self and robust community involvement across the life span of genetic studies. CONCLUSION: It is important for researchers and genetic counselors to understand the sociocultural underpinnings of African immigrants about genetics and genomics research as an initial step to encouraging their participation. PMID- 27687164 TI - Genome-wide association studies of immune, disease and production traits in indigenous chicken ecotypes. AB - BACKGROUND: The majority of chickens in sub-Saharan Africa are indigenous ecotypes, well adapted to the local environment and raised in scavenging production systems. Although they are generally resilient to disease challenge, routine vaccination and biosecurity measures are rarely applied and infectious diseases remain a major cause of mortality and reduced productivity. Management and genetic improvement programmes are hampered by lack of routine data recording. Selective breeding based on genomic technologies may provide the means to enhance sustainability. In this study, we investigated the genetic architecture of antibody response to four major infectious diseases [infectious bursal disease (IBDV), Marek's disease (MDV), fowl typhoid (SG), fowl cholera (PM)] and resistance to Eimeria and cestode parasitism, along with two production traits [body weight and body condition score (BCS)] in two distinct indigenous Ethiopian chicken ecotypes. We conducted variance component analyses, genome-wide association studies, and pathway and selective sweep analyses. RESULTS: The large majority of birds was found to have antibody titres for all pathogens and were infected with both parasites, suggesting almost universal exposure. We derived significant moderate to high heritabilities for IBDV, MDV and PM antibody titres, cestodes infestation, body weight and BCS. We identified single nucleotide polymorphisms (SNPs) with genome-wide significance for each trait. Based on these associations, we identified for each trait, pathways, networks and functional gene clusters that include plausible candidate genes. Selective sweep analyses revealed a locus on chromosome 18 associated with viral antibody titres and resistance to Eimeria parasitism that is within a positive selection signal. We found no significant genetic correlations between production, immune and disease traits, implying that selection for altered antibody response and/or disease resistance will not affect production. CONCLUSIONS: We confirmed the presence of genetic variability and identified SNPs significantly associated with immune, disease and production traits in indigenous village chickens. Results underpin the feasibility of concomitant genetic improvement for enhanced antibody response, resistance to parasitism and productivity within and across indigenous chicken ecotypes. PMID- 27687165 TI - Brain natriuretic peptide suppresses pain induced by BmK I, a sodium channel specific modulator, in rats. AB - BACKGROUND: A previous study found that brain natriuretic peptide (BNP) inhibited inflammatory pain via activating its receptor natriuretic peptide receptor A (NPRA) in nociceptive sensory neurons. A recent study found that functional NPRA is expressed in almost all the trigeminal ganglion (TG) neurons at membrane level suggesting a potentially important role for BNP in migraine pathophysiology. METHODS: An inflammatory pain model was produced by subcutaneous injection of BmK I, a sodium channel-specific modulator from venom of Chinese scorpion Buthus martensi Karsch. Quantitative PCR, Western Blot, and immunohistochemistry were used to detect mRNA and protein expression of BNP and NPRA in dorsal root ganglion (DRG) and dorsal horn of spinal cord. Whole-cell patch clamping experiments were conducted to record large-conductance Ca2+-activated K+ (BKCa) currents of membrane excitability of DRG neurons. Spontaneous and evoked pain behaviors were examined. RESULTS: The mRNA and protein expression of BNP and NPRA was up-regulated in DRG and dorsal horn of spinal cord after BmK I injection. The BNP and NPRA was preferentially expressed in small-sized DRG neurons among which BNP was expressed in both CGRP-positive and IB4-positive neurons while NPRA was preferentially expressed in CGRP-positive neurons. BNP increased the open probability of BKCa channels and suppressed the membrane excitability of small sized DRG neurons. Intrathecal injection of BNP significantly inhibited BmK induced pain behaviors including both spontaneous and evoked pain behaviors. CONCLUSIONS: These results suggested that BNP might play an important role as an endogenous pain reliever in BmK I-induced inflammatory pain condition. It is also suggested that BNP might play a similar role in other pathophysiological pain conditions including migraine. PMID- 27687166 TI - Radial Head Subluxation: Factors Associated with Its Recurrence and Radiographic Evaluation in a Tertiary Pediatric Emergency Department. AB - BACKGROUND: Radial head subluxation (RHS) is a common complaint seen in the pediatric emergency department in children ages 6 months to 4 years. Classically, injury occurs due to axial traction on the arm, but this mechanism is not universal. Some patients will have recurrent RHS; some may undergo x-ray (XR) evaluation for alternative diagnosis. OBJECTIVES: To determine factors associated with recurrences and radiographic evaluations in RHS. METHODS: A retrospective study with inclusion criteria: under 10 years of age with discharge diagnosis "nursemaid," "radial head," or "subluxation." We examined factors associated with RHS recurrences, circumstances when radiographic evaluations performed, physician's training background (pediatric vs. general emergency medicine), mechanisms of injury, and demographic factors including age, gender, and arm involved. RESULTS: In 246 visits, median age was 27 months (interquartile range 16.1), with females comprising 55.7% (n = 137), and left-sided predominance (52%, n = 130). Mechanisms of injury were classified as "pull" (65.9%, n = 162), "non pull" (15.9%, n = 39), and "unknown" (18.3%, n = 45). Eighteen patients with recurring RHS were more likely to be male (p = 0.008). In 61 visits where radiography was performed, patients were older (p = 0.03), with a higher frequency seen in non-pull and unknown mechanism (p = 0.0001). No significant difference was found in frequency of radiographs obtained in regard to physician training (p = 0.4660). CONCLUSION: RHS can result from a myriad of mechanisms. We found that recurrence was more likely in male patients. Factors associated with radiographic evaluation included atypical mechanism, older age, and unclear history, regardless of physician training background.

PMID- 27687168 TI - Effect of a Multi-Diagnosis Observation Unit on Emergency Department Length of Stay and Inpatient Admission Rate at Two Canadian Hospitals. AB - BACKGROUND: Observation units (OUs) have been shown to reduce emergency department (ED) lengths of stay (LOS) and admissions. Most published studies have been on OUs managing single complaints. OBJECTIVE: Our aim was to determine whether an OU reduces ED LOS and hospital admission rates for adults with a variety of presenting complaints. METHODS: We comparatively evaluated two hospitals in British Columbia, Canada (hereafter ED A and ED B) using a pre-post design. Data were extracted from administrative databases. The post-OU cohort included all adults presenting 6 months after OU implementation. The pre-OU cohort included all adults presenting in the same 6-month period 1 year before OU implementation. RESULTS: There were 109,625 patient visits during the study period. Of the 56,832 visits during the post-OU period (27,512 to ED A and 29,318 to ED B), 1.9% were managed in the OU in ED A and 1.4% in ED B. Implementation was associated with an increase in the median ED LOS at ED A (179.0 min pre vs. 192.0 min post [+13.0 min]; p < 0.001; mean difference -12.5 min, 95% confidence interval [CI] -15.2 to -9.9 min), but no change at ED B (182.0 min pre vs. 182.0 min post; p = 0.55; mean difference +2.0 min, 95% CI -0.7 to +4.7 min). Implementation significantly decreased the hospital admission rate for ED A (17.8% pre to 17.0% post [-0.8%], 95% CI -0.18% to 0.15%; p < 0.05) and did not significantly change the hospital admission rate at ED B (18.9% pre to 18.3% post [-0.6%], 95% CI -1.19% to -0.09%; p = 0.09). CONCLUSIONS: A multi-diagnosis OU can reduce hospital admission rate in a site-specific manner. In contrast to previous studies, we did not find that an OU reduced ED LOS. Further research is needed to determine whether OUs can reduce ED overcrowding. PMID- 27687169 TI - Influenza in the Emergency Department: Vaccination, Diagnosis, and Treatment. PMID- 27687170 TI - Catamenial Epilepsy: The Menstrual Cycle as a Clue to Predict Future Refractory Seizures. AB - BACKGROUND: Catamenial epilepsy is defined as an increase in the frequency of seizures during a particular phase of the menstrual cycle. The increased seizure frequency is attributed to the cyclic variation and neuroactive properties of endogenous steroid hormones. It is estimated that more than one-third of women with epilepsy experience catamenial seizure exacerbation. CASE REPORT: We present the case of a young female patient who presented to the emergency department with an increase in seizure frequency that coincided with her menstrual cycle, despite complete medication compliance. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is important for the emergency physician to consider catamenial epilepsy in the differential diagnosis for secondary causes of seizure to ensure appropriate follow-up, as well as improve the quality of life of patients suffering from uncontrolled seizures. PMID- 27687171 TI - Emergent Needle Aspiration of an Orbital Subperiosteal Hematoma. AB - BACKGROUND: Delayed presentation of orbital trauma as an acute subperiosteal hematoma. CASE REPORT: A 12-year-boy developed sudden painful abaxial proptosis of the left eyeball 15 days after blunt trauma over the forehead. On contrast enhanced computed tomography, a heterogeneous, hypodense, non-enhancing mass with biconvex contour was seen adjacent to the orbital roof. Direct needle drainage was performed and about 10 mL dark blood was aspirated. Proptosis reduced immediately and resolved completely at 2 weeks follow-up. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Sudden proptosis with no immediate history of trauma can be alarming for the emergency physician. Familiarity with this clinical entity and early drainage can decrease morbidity. PMID- 27687172 TI - Malpractice Litigation and Testicular Torsion in the Spanish Setting: Lessons to Learn. PMID- 27687173 TI - Airway Management of a Patient with an Acute Floor of the Mouth Hematoma after Dental Implant Surgery in the Lower Jaw. AB - BACKGROUND: Over the last decades, dental implants have become increasingly popular in the prosthetic rehabilitation of patients. This has subsequently led to an increase of perioperative complications. Obstruction of the airway as a result of a floor of mouth hematoma after dental implant surgery is a rare but life-threatening complication. CASE REPORT: A 62-year-old man presented to the emergency department with a compromised airway caused by a hematoma in the floor of the mouth that occurred during dental implant surgery in the edentulous anterior mandible. Computed tomography angiography images revealed an elevation of the floor of mouth with subsequent occlusion of the airway. In addition, a perforation of the lingual mandibular cortical plate was observed that was caused by two malpositioned dental implants. Awake fiberoptic intubation was immediately performed, the two malpositioned dental implants were subsequently removed, and the patient was extubated after 3 days. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Perforation of the lingual mandibular cortical plate during dental implant surgery can lead to life-threatening bleeding in the floor of the mouth. This condition can be successfully treated by awake fiberoptic intubation and, if necessary, the malpositioned dental implants can be subsequently removed. PMID- 27687174 TI - Delayed Antitoxin Treatment of Two Adult Patients with Botulism after Cosmetic Injection of Botulinum Type A Toxin. AB - BACKGROUND: Injection of botulinum toxin type A for cosmetic purposes is common. It is believed to be safe, but adverse reactions have been reported, including dysphagia, generalized paralysis, respiratory depression, and death caused by focal injection of the toxin. Early administration of antitoxin in patients with adverse reactions is the mainstay of management, but the time window for its clinical efficacy is not well defined. CASE REPORTS: Two female adult patients with clinical botulism after botulinum toxin type A injection are described. Both patients had received intramuscular injection of botulinum toxin type A in their calves at beauty shops for cosmetic reasons. They developed clinical botulism about 3 days postinjection. They presented late to the emergency department. Monovalent type A botulinum antitoxin was administered 7 and 9 days from symptom onset, respectively. Both patients showed clinical improvement after the antitoxin treatment. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Patients may present to the emergency department with systemic effects of botulinum toxin type A after cosmetic injection. Clinical efficacy of botulinum antitoxin treatment was observed in two patients who were given the drug 7 and 9 days after the occurrence of symptoms of botulism after cosmetic injection of botulinum toxin type A. It may be worthwhile to commence antitoxin treatment even if patients present late. PMID- 27687176 TI - The role of patelloplasty in total knee arthroplasty. AB - INTRODUCTION: Anterior knee pain (AKP) is a frequent complication after total knee arthroplasty (TKA). Patelloplasty, defined as reshaping the patella for optimal tracking in the trochlea, has been proposed to reduce the rate of this complication in patellar retaining implants. Aim of this study was to analyze the available literature regarding the outcomes of patelloplasty and to assess its methodological quality. MATERIALS AND METHODS: A comprehensive review of the English literature was performed using the keywords "total knee arthroplasty", "patelloplasty" and "patellaplasty" with no limit regarding the year of publication. All the selected articles were evaluated with the Coleman score. RESULTS: Seven full text articles were retrieved. The initial cohort included 461 knees in the study groups and 465 in the control groups. At an average FU of 70.6 months 447 knees were reviewed in the study group and 447 in the control groups. The global rate of AKP after patelloplasty was 11.3 % which compared to 7.9 % in the patella resurfacing control group. No signs of specific patellar complications due to patelloplasty were reported. Average Coleman score was 66.9. CONCLUSION: Most of the literature has barely sufficient methodological quality. Patelloplasty aims at reducing patellar thickness and improve its tracking with TKA. This procedure is a safe and easy option with no reported adverse effects. In the included studies, outcome seemed to be superior in comparison with isolated osteophyte removal and denervation with a lower rate of AKP. The included studies, however, report a lower rate of AKP following TKA with patellar resurfacing. Patelloplasty may have the potential to improve the outcome of patellar retaining implants.

AB - The critical need for species preservation has driven the evolution of mechanisms that integrate stress signals from both exogenous and endogenous sources. Past research has been largely focused on cell-autonomous stress responses; however, recently their systemic outcomes within an organism and their implications at the ecological and species levels have emerged. Maintenance of species depends on the high fidelity transmission of the genome over infinite generations; thus, many pathways exist to monitor and restore the integrity of the genome and to coordinate DNA repair with other cellular processes, such as cell division and growth. The specifics of these DNA damage responses (DDRs) vary vastly but some general themes are conserved from ancient organisms, such as bacteria and archaea, to humans. Despite decades of research, however, DDRs still have many layers of complexity and some surprises left to be discovered. One of the most interesting current research topics is the link between DNA damage and stress resistance: the outcomes of DDRs can protect the organism from other secondary challenges. At this time, these types of responses are best characterized in bacteria and the simple metazoan model, Caenorhabditis elegans, but it is becoming clear that similar processes also exist in higher organisms. PMID- 27687177 TI - Safety of simultaneous bilateral total knee arthroplasty using an extramedullary referencing system: results from 2098 consecutive patients. AB - INTRODUCTION: Simultaneous bilateral total knee arthroplasty (TKA) has been associated with a high risk of morbidity and mortality. The orthopedic surgeon must, therefore, decide whether bilateral simultaneous TKA is a safe operation to perform and endeavor to decrease the risk of serious complications or even death. METHODS: This retrospective review included 2098 consecutive patients who underwent bilateral simultaneous TKAs by the protocol used in our institution, including the use of extramedullary instruments to minimize medullary canal invasion and overlapping procedures for both knees to decrease operation time. RESULTS: The incidence rate of occurred complications was 0.33 % for symptomatic pulmonary embolism, 0.62 % for deep surgical infection requiring revision surgery, 0.05 % for 14-day mortality, 1.14 % for adverse cardiac events, and 0.76 % for postsurgical delirium within the 1-year follow-up. CONCLUSIONS: Our protocols, including the use of an extramedullary referencing system and overlapping procedures for both knees, may be considered to decrease the perioperative short-term morbidity and 14-day mortality rates in simultaneous bilateral TKA.

PMID- 27687183 TI - Multitemporal analysis of forest fragmentation in Hindu Kush Himalaya-a case study from Khangchendzonga Biosphere Reserve, Sikkim, India. AB - Forests in the mountains are a treasure trove; harbour a large biodiversity; and provide fodder, firewood, timber and non-timber forest products; all of these are essential for human survival in the highest mountains on earth. The present paper attempts a spatiotemporal assessment of forest fragmentation and changes in land use land cover (LULC) pattern using multitemporal satellite data over a time span of around a decade (2000-2009), within the third highest protected area (PA) in the world. The fragmentation analysis using Landscape Fragmentation Tool (LFT) depicts a decrease in large core, edge and patches areas by 5.93, 3.64 and 0.66 %, respectively, while an increase in non-forest and perforated areas by 6.59 and 4.01 %, respectively. The land cover dynamics shows a decrease in open forest, alpine scrub, alpine meadows, snow and hill shadow areas by 2.81, 0.39, 8.18, 3.46 and 0.60 %, respectively, and there is an increase in dense forest and glacier area by 4.79 and 10.65 %, respectively. The change analysis shows a major transformation in areas from open forest to dense forest and from alpine meadows to alpine scrub. In order to quantify changes induced by forest fragmentation and to characterize composition and configuration of LULC mosaics, fragmentation indices were computed using Fragstats at class level, showing the signs of accelerated fragmentation. The outcome of the analysis revealed the effectiveness of geospatial tools coupled with landscape ecology in characterization and quantification of forest fragmentation and land cover changes. The present study provides a baseline database for sustainable conservation planning that will benefit the subsistence livelihoods in the region. Recommendations made based on the present analysis will help to recover forest and halt the pessimistic effects of fragmentation and land cover changes on biodiversity and ecosystem services in the region. PMID- 27687184 TI - The effects of soil liming and sewage sludge application on dynamics of copper fractions and total copper concentration. AB - The paper deals with effects of liming and different doses of municipal sewage sludge (5, 10, and 15 % of soil mass) on copper speciation in soil. In all samples, pH was determined together with total copper concentration, which was measured with the ICP-AES method. Concentration of copper chemical fractions was determined using the seven-step procedure of Zeien and Brummer. In the soil treated with the highest dose of sludge (15 %), there was, compared to the control, a twofold increase in the concentration of copper and a threefold increase in the concentration of nitrogen. Copper speciation analysis showed that in the municipal sewage sludge the easily soluble and exchangeable fractions (F1 and F2) constituted only a small share of copper with the highest amount of this metal in the organic (F4) and residual (F7) fractions. In the soil, at the beginning of the experiment, the highest share was in the organic fraction (F4), the residual fraction (F7) but also in the fraction where copper is bound to amorphous iron oxides (F5). After 420 days, at the end of the experiment, the highest amount of copper was mainly in the organic fraction (F4) and in the fraction with amorphous iron oxides (F5). Due to mineralization of organic matter in the sewage sludge, copper was released into the soil with the share of the residual fraction (F7) decreasing. In this fraction, there was much more copper in limed soil than in non-limed soil. PMID- 27687185 TI - Diffusive gradients in thin films measurement of sulfur stable isotope variations in labile soil sulfate. AB - A diffusive gradient in thin films (DGT) technique, based on a strongly basic anion exchange resin (Amberlite IRA-400), was successfully tested for 34S/32S analysis in labile soil sulfate. Separation of matrix elements (Na, K, and Ca) that potentially cause non-spectral interferences in 34S/32S analysis by MC ICP MS (multi-collector inductively coupled plasma-mass spectrometry) during sampling of sulfate was demonstrated. No isotopic fractionation caused by diffusion or elution of sulfate was observed below a resin gel disc loading of <=79 MUg S. Above this threshold, fractionation towards 34S was observed. The method was applied to 11 different topsoils and one mineral soil profile (0-100 cm depth) and compared with soil sulfate extraction by water. The S amount and isotopic ratio in DGT-S and water-extractable sulfate correlated significantly (r 2 = 0.89 and r 2 = 0.74 for the 11 topsoils, respectively). The systematically lower 34S/32S isotope ratios of the DGT-S were ascribed to mineralization of organic S. PMID- 27687186 TI - High-throughput and sensitive analysis of urinary heterocyclic aromatic amines using isotope-dilution liquid chromatography-tandem mass spectrometry and robotic sample preparation system. AB - Heterocyclic aromatic amines (HCAA) are listed by the US Food and Drug Administration (FDA) as harmful or potentially harmful constituents of tobacco smoke. However, quantifying HCAA exposure is challenging. In this study, we developed a sensitive, precise, and accurate isotope dilution, liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to quantify urinary HCAAs in smokers and nonsmokers. The high-throughput robotic sample preparation system could handle a throughput of over 300 samples per day, while maintaining intra-day and inter-day imprecision and bias <=10 %. The limits of detection of carcinogenic HCAAs ranged from 0.31 to 0.83 pg/mL. The validated method was applied to measure HCAAs in urine collected from smokers and non-smokers. This sensitive and efficient analytical method is ideal to support large-scale biomonitoring studies of HCAA exposure.

PMID- 27687187 TI - The strategy of repeat stereotactic radiosurgery without whole brain radiation treatment for new brain metastases: Outcomes and implications for follow-up monitoring. AB - PURPOSE: Stereotactic radiosurgery (SRS) is widely used to treat brain metastases in place of whole brain radiation therapy (WBRT), with the goal of reducing treatment toxicity balanced against the risk of developing new metastases. We evaluated outcomes of repeated courses of SRS in the management of new brain metastases as an alternative to salvage WBRT. METHODS AND MATERIALS: We conducted a single-institution retrospective review of 239 patients treated with SRS without WBRT for brain metastases from 2004 to 2014. Eighty-six patients received at least 2 courses of SRS for new brain metastases. Outcome metrics included survival, development of symptomatic new brain metastases, neurologic symptoms at death or last follow-up, and ultimate WBRT. RESULTS: Eighty-six patients (median age, 59 years) underwent a median of 2 courses of SRS (range, 2-6), with a median of 2 lesions treated initially and on retreatment. The median interval between SRS treatments was 5.8 months (range, 1.2-69.1). New brain metastases after initial radiosurgery were detected by routine imaging in 87% of cases. Median overall survival from repeat SRS was 13.0 months (range, 0.3-64.5) and from initial brain metastasis diagnosis 25.0 months (range, 2.0-68.1). On multivariate analysis, Eastern Cooperative Oncology Group performance status 0-1 (hazard ratio [HR], 0.37; 95% confidence interval [CI], 0.15-0.90; P=.029), controlled extracranial disease (HR, 0.35; 95% CI, 0.13-0.94; P=.038), and interval between initial and second SRS >6 months (HR, 0.49; 95% CI, 0.25-0.96; P=.037) correlated with improved overall survival from brain metastasis diagnosis. A total of 24.7% of patients had symptomatic intracranial metastatic disease at death or last follow-up, and 26.7% ultimately received WBRT. CONCLUSION: Repeated SRS is a reasonable option for patients with new brain metastases, as our results suggest favorable survival outcomes with this approach. New lesions infrequently caused neurologic symptoms before routine imaging detection, and a minority of patients had symptomatic intracranial disease at death or last follow-up. PMID- 27687188 TI - The American Board of Radiology radiation oncology Maintenance of Certification Part 3 Modular Examination: Evaluation of the first administration. AB - Based on data obtained from clinical practice analysis (CPA) surveys performed in 2010 and 2013, and with input from its maintenance of certification (MOC) advisory committee, the American Board of Radiology (ABR) recognized that the changing nature of radiation oncology practice patterns warranted revisions of its MOC Part III cognitive examination. One significant revision was the introduction of a modular examination that allowed diplomates to select specific areas of clinical interest. The module-based items represented 30% (60 of 200) of total examination content. The new modular examination was administered for the first time in October 2015. Logistics of examination development, administration, and diplomate post-examination survey responses are reviewed. PMID- 27687189 TI - Delineation of radiation therapy target volumes for cutaneous malignancies involving the ophthalmic nerve (cranial nerve V-1) pathway. AB - PURPOSE: The ophthalmic nerve (cranial nerve V-1) runs in close proximity to the globe, optic nerve, chiasm, and brain. The purpose of this study was to provide contouring guidance using computed tomography (CT)-identifiable landmarks, based on an analysis of skin cancer patients with V-1 invasion. METHODS AND MATERIALS: Radiation oncology planning CT scans were analyzed for landmarks to guide V-1 target delineation from the skin surface to the trigeminal ganglion. Axial and coronal magnetic resonance imaging (MRI) sequences were fused with the planning CT to confirm soft-tissue findings and identify enhancement related to perineural spread. CT/MRI-based anatomic landmarks were catalogued and described on an atlas. RESULTS: Soft-tissue and bony landmarks were confirmed as consistently identifiable on CT with assistance from fused MRI. A reference atlas was developed that shows the entirety of the V-1 pathway on consecutive CT slices. CONCLUSIONS: Initial delineation of the V-1 pathway can be accomplished using CT visualized landmarks confirmed on fused MRI. This CT/MRI atlas will assist radiation oncologists in delineation of the V-1 pathway. PMID- 27687190 TI - Mitral Regurgitation in Patients With Hypertrophic Obstructive Cardiomyopathy: Implications for Concomitant Valve Procedures. AB - BACKGROUND: Incidence and outcome of mitral valve (MV) surgery are unknown in patients with hypertrophic obstructive cardiomyopathy (HOCM) undergoing extended transaortic septal myectomy. OBJECTIVES: This study sought to define indications and suitable operative strategy for mitral regurgitation (MR) in patients with HOCM. METHODS: A total of 2,107 septal myectomy operations performed in adults from January 1993 to May 2014 at Mayo Clinic in Rochester, Minnesota, were retrospectively reviewed. Patients with prior MV operation and apical hypertrophic cardiomyopathy were excluded. Overall, 2,004 operations were performed in 1,993 patients. RESULTS: Pre-operative MR was grade >=3 (of 4) in 1,152 operations (57.5%). Systolic anterior motion of mitral leaflets caused the MR in most patients. However, intrinsic MV disease was identified pre-operatively in 99 patients, all of whom had MV surgery (with septal myectomy). In 1,905 operations, no intrinsic MV disease was identified pre-operatively; in 1,830 (96.1%), septal myectomy was performed without a direct MV procedure. For 75 patients, intrinsic MV disease discovered intraoperatively led to concomitant MV repair (86.7%) or replacement (13.3%). After isolated septal myectomy, the percentage of patients with MR grade >=3 decreased from 54.3% to 1.7% (p = 0.001) on early post-operative echocardiography. Among 174 patients with concomitant MV surgery, late survival was superior with MV repair (n = 133 [76.4%]) versus replacement (10-year survival: 80.0% vs. 55.2%; p = 0.002). CONCLUSIONS: In most patients with HOCM, MR related to systolic anterior motion of the MV is relieved through adequate myectomy. Concomitant MV surgery is rarely necessary unless intrinsic MV disease is present. When MV procedures are required, repair is preferred because of improved survival compared with replacement.

PMID- 27687192 TI - Association of Changes in Abdominal Fat Quantity and Quality With Incident Cardiovascular Disease Risk Factors. AB - BACKGROUND: Subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) are associated with adverse cardiometabolic risk profiles. OBJECTIVES: This study explored the degree to which changes in abdominal fat quantity and quality are associated with changes in cardiovascular disease (CVD) risk factors. METHODS: Study participants (n = 1,106; 44.1% women; mean baseline age 45.1 years) were drawn from the Framingham Heart Study Third Generation cohort who participated in the computed tomography (CT) substudy Exams 1 and 2. Participants were followed for 6.1 years on average. Abdominal adipose tissue volume in cm(3) and attenuation in Hounsfield units (HU) were determined by CT-acquired abdominal scans. RESULTS: The mean fat volume change was an increase of 602 cm(3) for SAT and an increase of 703 cm(3) for VAT; the mean fat attenuation change was a decrease of 5.5 HU for SAT and an increase of 0.07 HU for VAT. An increase in fat volume and decrease in fat attenuation were associated with adverse changes in CVD risk factors. An additional 500 cm(3) increase in fat volume was associated with incident hypertension (odds ratio [OR]: 1.21 for SAT; OR: 1.30 for VAT), hypertriglyceridemia (OR: 1.15 for SAT; OR: 1.56 for VAT), and metabolic syndrome (OR: 1.43 for SAT; OR: 1.82 for VAT; all p < 0.05). Similar trends were observed for each additional 5 HU decrease in abdominal adipose tissue attenuation. Most associations remained significant even after further accounting for body mass index change, waist circumference change, or respective abdominal adipose tissue volumes. CONCLUSIONS: Increasing accumulation of fat quantity and decreasing fat attenuation are associated with worsening of CVD risk factors beyond the associations with generalized adiposity, central adiposity, or respective adipose tissue volumes. PMID- 27687194 TI - Transcatheter Pulmonary Valve Replacement Reduces Tricuspid Regurgitation in Patients With Right Ventricular Volume/Pressure Overload. AB - BACKGROUND: Tricuspid regurgitation (TR) is a common and important comorbidity in patients with postoperative right ventricular outflow tract (RVOT) obstruction or pulmonary regurgitation (PR). Transcatheter pulmonary valve replacement (TPVR) has become a useful tool in the management of postoperative RVOT obstruction and PR, but it is unknown whether relief of the right ventricular volume and/or pressure overload by TPVR will have a beneficial effect on TR, as is often seen with surgical pulmonary valve replacement. OBJECTIVES: This study sought to assess the prevalence of and factors associated with significant TR in patients undergoing TPVR for RVOT obstruction or PR. METHODS: Data were combined from 3 prospective multicenter trials of patients referred for TPVR. Follow-up data through 5 years post-implantation were analyzed. RESULTS: Of 300 patients studied, 77 (25.6%) had moderate or severe TR at baseline. After TPVR, TR severity was improved in 65% of those patients, and more than one-half had mild TR or less TR at discharge. Of 13 patients with severe TR pre-implantation, only 1 had severe TR at 1-year follow-up and beyond. Moderate or severe baseline TR was associated with shorter freedom from RVOT reintervention after TPVR. CONCLUSIONS: In this prospective multicenter study of post-operative patients with RVOT obstruction and/or PR, TR was common. In patients with significant baseline TR, TPVR resulted in clinically relevant acute reductions in TR that persisted over at least 5 years of follow-up. These observations support the application of TPVR therapy in patients with RVOT obstruction or PR who are anatomically suitable, even in the setting of significant concomitant TR.

PMID- 27687196 TI - Cardiac Recovery During Long-Term Left Ventricular Assist Device Support. AB - BACKGROUND: The number of centers with left ventricular assist device (LVAD) research programs focused on cardiac recovery is very small. Therefore, this phenomenon has been reported in real-world multi-center registries as a rare event. OBJECTIVES: This study evaluated the incidence of cardiac recovery with an a priori LVAD implantation strategy of bridge-to-recovery (BTR) and constructed a recovery predictive model. METHODS: The study included LVAD recipients registered in the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS). Cardiac recovery was evaluated in BTR and non-BTR patients. A weighted score was derived and externally validated in patients of the Utah Cardiac Recovery (UCAR) program. RESULTS: Of 15,138 INTERMACS patients, cardiac recovery occurred in 192 (1.3%). The incidence of recovery was 11.2% (n = 14) in BTR compared with 1.2% (n = 178) in non-BTR patients (p < 0.0001). Independent predictors of recovery included: age <50 years, non-ischemic cardiomyopathy, time from cardiac diagnosis <2 years, absence of ICD, creatinine <=1.2 mg/dl, and LVEDD <6.5 cm (c-index: 0.85; p < 0.0001). A weighted score termed I-CARS, effectively stratified patients based on their probability of recovery. I-CARS was validated in the UCAR cohort (n = 190) with good performance (AUC: 0.94; 95% CI: 0.91 to 0.98). One-year survival after LVAD explantation, available in INTERMACS for 21 (11%) patients, was 86%. CONCLUSIONS: The incidence of cardiac recovery is higher in patients implanted with an a priori BTR strategy. We developed a simple tool to help identify patients in whom recovery is feasible. In BTR patients with favorable characteristics, I-CARS suggests a 24% probability of successful LVAD explantation. Large-scale studies to better address post explantation outcomes are warranted.

PMID- 27687198 TI - Preclinical Development of a MicroRNA-Based Therapy for Elderly Patients With Myocardial Infarction. AB - BACKGROUND: Aging populations show higher incidences of myocardial infarction (MI) and heart failure (HF). Cardiac remodeling post-MI leads to progressive impaired cardiac function caused by a disarray of several processes including derailed autophagy. Microribonucleic acids (miRNAs) are known to be key players in cardiovascular disease but their involvement in cardiac autophagy and aging is not well understood. OBJECTIVES: This study sought to identify new miRNA candidates that regulate cardiac autophagy and aging. METHODS: We exploited a high-throughput, fluorescence-activated cell sorting-based green fluorescent protein-LC3 detection method to measure the autophagic flux in cardiomyocytes after transfection of a precursor miRNA library consisting of 380 miRNAs. This was followed by a series of molecular and in vivo studies. RESULTS: Together with additional expression screenings, we identified miR-22 as an abundant and strong inhibitor of the cardiac autophagy process. Cardiac miR-22 expression levels increased during aging of mice as well as in aging neonatal cardiomyocytes in vitro by a P53-dependent mechanism. Inhibition of miR-22 in aging cardiomyocytes in vitro activated autophagy and inhibited cellular hypertrophy. Pharmacological inhibition of miR-22 post-MI in older mice activated cardiac autophagy, prevented post-infarction remodeling, and improved cardiac function compared with control subjects. Interestingly, similar effects were less pronounced in younger mice with significantly lower cardiac miR-22 expression levels. In addition, circulating levels of miR-22 in 154 patients with systolic HF were highly associated with early mortality. CONCLUSIONS: We concluded that miR-22 is an important regulator of cardiac autophagy and a potential therapeutic target, especially in the older myocardium. Finally, circulating miR-22 provides prognostic information for HF patients, highlighting miR-22 as a promising therapeutic and biomarker candidate for cardiovascular disorders. PMID- 27687200 TI - Hyperkalemia in Heart Failure. AB - Disorders of potassium homeostasis can potentiate the already elevated risk of arrhythmia in heart failure. Heart failure patients have a high prevalence of chronic kidney disease, which further heightens the risk of hyperkalemia, especially when renin-angiotensin-aldosterone system inhibitors are used. Acute treatment for hyperkalemia may not be tolerated in the long term. Recent data for patiromer and sodium zirconium cyclosilicate, used to treat and prevent high serum potassium levels on a more chronic basis, have sparked interest in the treatment of hyperkalemia, as well as the potential use of renin-angiotensin aldosterone system inhibitors in patients who were previously unable to take these drugs or tolerated only low doses. This review discusses the epidemiology, pathophysiology, and outcomes of hyperkalemia in heart failure; provides an overview of traditional and novel ways to approach management of hyperkalemia; and discusses the need for further research to optimally treat heart failure. PMID- 27687201 TI - Implantable Electronic Cardiac Devices and Compatibility With Magnetic Resonance Imaging. AB - There is a growing population of patients with implanted electronic cardiac devices and a concomitant increase in the use of magnetic resonance (MR). There are theoretical safety risks posed to such devices by MR. However, there are now considerable laboratory data and clinical experience demonstrating safety in this setting, assuming appropriate device selection and patient monitoring. Herein, we review these data and our safety protocol and the new generation of devices that have been prospectively designed and tested to be safe for MR scanning, assuming certain conditions are met (i.e., devices that are MR-conditional). We also argue that the available data do not support a complete transition to implantation of MR-conditional devices.

PMID- 27687210 TI - Lack of mitochondrial DNA impairs chemical hypoxia-induced autophagy in liver tumor cells through ROS-AMPK-ULK1 signaling dysregulation independently of HIF 1alpha. AB - Alterations in mitochondrial DNA (mtDNA) and autophagy activation are common events in tumors. Here we have investigated the effect of mitochondrial genome depletion on chemical hypoxia-induced autophagy in liver tumor cells. Human SK Hep-1 wild-type and mtDNA-depleted (Rho) cells were exposed to the hypoxia mimetic agents CoCl2 and deferoxamine (DFO). Up-regulation of HIF-1alpha, but not HIF-2alpha was observed. The expression of several HIF-1alpha target genes was also found. In human SK-Hep-1 and mouse Hepa 1-6 liver tumor cells, but not in the counterpart Rho derived lines, chemical hypoxia increased the abundance of autophagosomes and autolysosomes. In wild-type and Rho cells, chemical hypoxia induced down-regulation of HIF-1alpha-dependent autophagy inhibitors Bcl-2 and mTOR, whereas activation of AMPK/ULK1-mediated pro-autophagy pathway occurred only in wild-type cells. Chemical (compound C) and genetic (shRNA) inhibition of AMPK activation resulted in reduced autophagy. ATP levels were similar in both cell types, whereas constitutive and chemical hypoxia-induced reactive oxygen species (ROS) generation was lower in Rho cells. In wild-type cells, the antioxidant N-acetylcysteine blocked CoCl2- and DFO-induced AMPK and autophagy activation, but not endoplasmic reticulum stress induced by CoCl2. Enhanced Bax alpha/Bcl-2 ratio and cell death was induced by hypoxia mimetic agents more markedly in wild-type than in Rho cells. Upon blocking autophagy activation with 3-methyladenine, DFO-induced cell death was partially prevented whereas that induced by CoCl2 was increased, but only in wild-type cells. These results suggest that mitochondrial dysfunction associated with the lack of mtDNA impairs the signaling pathways mediated by ROS, controlling autophagy activation in liver tumor cells, which may contributes to cancer development. PMID- 27687212 TI - Efficacy of Cognitive Behavioral Therapy for Generalized Anxiety Disorder in Older Adults: Systematic Review, Meta-Analysis, and Meta-Regression. AB - OBJECTIVE: Generalized anxiety disorder (GAD) is a common disorder in older adults producing functional impairment, and psychotherapy is the preferred treatment option. Meta-analytic methods sought to determine the efficacy of outpatient cognitive behavioral therapy (CBT) with respect to the hallmark feature of GAD-uncontrolled and excessive worry. In order to optimize clinical applicability, variables associated with GAD treatment outcomes were also examined. METHODS: Systematic search of relevant databases and iterative searches of references from articles retrieved. All studies were required to have been a randomized control trial (RCT), to have used the Penn State Worry Questionnaire (PSWQ) or its abbreviated version (PSWQ-A) as an outcome measure, and to have conducted CBT with outpatient older adults. Fourteen RCTs (N = 985) were suitable and random-effects meta-analyses and univariate meta-regressions were conducted. RESULTS: At the end of treatment, and at 6-month follow-up, significant treatment effects favoring CBT were found in comparison to a waitlist or treatment-as usual. When CBT was compared with active controls, a small nonsignificant treatment advantage was found for CBT at the end of treatment, with equivalence of outcomes at follow-up. Treatment effect size of CBT for GAD was significantly associated with attrition rates and depression outcomes. CONCLUSIONS: CBT is more helpful than having no treatment for GAD in later life. Nevertheless, whether CBT shows long-term durability, or is superior to other commonly available treatments (such as supportive psychotherapy), remains to be tested. The relationship between treatment effects for GAD and depression following CBT warrants further research. PMID- 27687211 TI - Tissue metabolism and host-microbial interactions in the intestinal mucosa. AB - In recent years, studies in the gastrointestinal (GI) mucosa have taught us a number of important lessons related to tissue oxygenation and metabolism in health and disease. The highly vascularized mucosa lies immediately adjacent to an anaerobic lumen containing trillions of metabolically active microbes (i.e. the microbiome) that results in one of the more austere tissue microenvironments in the body. These studies have also implicated a prominent role for oxygen metabolism and hypoxia in inflammation, so called "inflammatory hypoxia", that results from the activation of multiple oxygen consuming enzymes. Inflammation associated shifts in the composition of the microbiome and microbial-derived metabolites have revealed a prominent role for the transcription factor hypoxia inducible factor (HIF) in the regulation of key target genes that promote inflammatory resolution. Analyses of these pathways have provided a multitude of opportunities for understanding basic mechanisms of both homeostasis and disease and have defined new targets for intervention. Here, we review recent advances in our understanding of metabolic influences on host-microbe interactions in the GI mucosa. PMID- 27687213 TI - Facilitators and barriers to the use of standing orders for vaccination in obstetrics and gynecology settings. AB - BACKGROUND: Many young and middle-aged women receive their primary health care from their obstetrician-gynecologists. A recent change to vaccination recommendations during pregnancy has forced the integration of new clinical processes at obstetrician-gynecology practices. Evidence-based best practices for vaccination delivery include the establishment of vaccination standing orders. OBJECTIVES: As part of an intervention to increase adoption of evidence-based vaccination strategies for women in safety-net and private obstetrician gynecology settings, we conducted a qualitative study to identify the facilitators and barriers experienced by obstetrician-gynecology sites when establishing vaccination standing orders. STUDY DESIGN: At 6 safety-net and private obstetrician-gynecology practices, 51 semistructured interviews were completed by trained qualitative researchers over 2 years with clinical staff and vaccination program personnel. Standardized qualitative research methods were used during data collection and team-based data analysis to identify major themes and subthemes within the interview data. RESULTS: All study practices achieved partial to full implementation of vaccine standing orders for human papillomavirus, tetanus diphtheria pertussis, and influenza vaccines. Facilitating factors for vaccine standing order adoption included process standardization, acceptance of a continual modification process, and staff training. Barriers to vaccine standing order adoption included practice- and staff-level competing demands, pregnant women's preference for medical providers to discuss vaccine information with them, and staff hesitation in determining HPV vaccine eligibility. CONCLUSIONS: With guidance and commitment to integration of new processes, obstetrician-gynecology practices are able to establish vaccine standing orders for pregnant and nonpregnant women. Attention to certain process barriers can aid the adoption of processes to support the delivery of vaccinations in obstetrician-gynecology practice setting, and provide access to preventive health care for many women. PMID- 27687214 TI - Dose-adjusted plasma concentrations of sublingual buprenorphine are lower during than after pregnancy. AB - BACKGROUND: Buprenorphine is a Food and Drug Administration-approved maintenance therapy for opioid use disorders and is increasingly being used in pregnant women with opioid use disorders as an alternative to methadone. Dosing of buprenorphine in pregnant women is based on the regimen recommended for nonpregnant females and males. Limited data are available defining the pharmacokinetic properties of sublingual buprenorphine administered during pregnancy. OBJECTIVE: This study evaluated the impact of physiological changes associated with pregnancy on the pharmacokinetics of sublingual buprenorphine during and after pregnancy. STUDY DESIGN: Pregnant women (n = 13), between 180/7 and 376/7 weeks' singleton gestation, receiving sublingual buprenorphine twice daily for opioid use disorders were studied. Pharmacokinetic-2 studies were performed between 18 and 25 weeks (n = 7), pharmacokinetic-3 studies were performed between 31 and 37 weeks (n = 11), and pharmacokinetic-P was performed 4-18 weeks postpartum (n = 10). On the day of the study, blood was withdrawn prior to the daily morning dose of buprenorphine and at 0.25, 0.5, 0.75, 1, 1.5, 2, 4, 8, and 12 hours after the dose. Buprenorphine plasma concentrations were analyzed by liquid chromatography tandem mass spectrometric detection. All pharmacokinetic parameters were observed or estimated using Microsoft Excel. Statistical analyses were performed to identify significant changes in study participants' buprenorphine pharmacokinetic parameter estimates over the duration of the study. Univariate linear and generalized linear mixed models were used to investigate changes in these measures over time, some of which were log transformed for normality. RESULTS: Dose-normalized (plasma concentration per dose) buprenorphine plasma concentrations were significantly lower during pregnancy (pharmacokinetic-2 plus pharmacokinetic-3) than during the postpartum period (pharmacokinetic-P). Specific pharmacokinetic parameters (and level of significance) were as follows: the area under the buprenorphine plasma concentration-time curves (P < .003), maximum buprenorphine concentrations (P < .018), buprenorphine concentrations at 0 hour (P < .002), and buprenorphine concentrations at 12 hours (P < .001). None of these parameters differed significantly during pregnancy (ie, pharmacokinetic 2 vs pharmacokinetic-3). The time to maximum buprenorphine concentrations did not differ significantly between groups. CONCLUSION: The dose-normalized plasma concentrations during a dosing interval and the overall exposure of buprenorphine (area under the buprenorphine plasma concentration-time curves) are lower throughout pregnancy compared with the postpartum period. This indicates an increase in apparent clearance of buprenorphine during pregnancy. These data suggest that pregnant women may need a higher dose of sublingual buprenorphine compared with postpartum individuals. The dose of buprenorphine should be assessed after delivery to maintain similar buprenorphine exposure during the postpartum period.

PMID- 27687216 TI - Explaining the recent decrease in US infant mortality rate, 2007-2013. AB - BACKGROUND: The US infant mortality rate has been steadily decreasing in recent years as has the preterm birth rate; preterm birth is a major factor associated with death during the first year of life. The degree to which changes in gestational age-specific mortality and changes in the distribution of births by gestational age have contributed to the decrease in the infant mortality rate requires clarification. OBJECTIVE: The objective of the study was to better understand the major contributors to the 2007-2013 infant mortality decline for the total population and for infants born to non-Hispanic black, non-Hispanic white, and Hispanic women. STUDY DESIGN: We identified births and infant deaths from 2007 and 2013 Centers for Disease Control and Prevention National Vital Statistics System's period linked birth and infant death files. We included all deaths and births for which there was a reported gestational age at birth on the birth certificate of 22 weeks or greater. The decrease in the infant mortality rate was disaggregated such that all of the change could be attributed to improvements in gestational age-specific infant mortality rates and changes in the distribution of gestational age, by week of gestation, using the Kitagawa method. Sensitivity analyses were performed to account for records in which the obstetric estimate of gestational age was missing and for deaths and births less than 22 weeks' gestation. Maternal race and ethnicity information was obtained from the birth certificate. RESULTS: The infant mortality rates after exclusions were 5.72 and 4.92 per 1000 live births for 2007 and 2013, respectively, with an absolute difference of -0.80 (14% decrease). Infant mortality rates declined by 11% for non-Hispanic whites, by 19% for non-Hispanic blacks, and by 14% for Hispanics during the period. Compared with 2007, the proportion of births in each gestational age category was lower in 2013 with the exception of 39 weeks during which there was an increase in the proportion of births from 30.1% in 2007 to 37.5% in 2013. Gestational age-specific mortality decreased for each gestational age category between 2007 and 2013 except 33 weeks and >42 weeks. About 31% of the decrease in the US infant mortality rate from 2007 through 2013 was due to changes in the gestational age distribution, and 69% was due to improvements in gestational age-specific survival. Improvements in the gestational age distribution from 2007 through 2013 benefited infants of non-Hispanic white women (48%) the most, followed by infants of non-Hispanic black (31%) and Hispanic (14%) women. CONCLUSION: Infant mortality improved between 2007 and 2013 as a result of both improvements in the distribution of gestational age at birth and improvements in survival after birth. The differential contribution of improvements in the gestational age distribution at birth by race and ethnicity suggests that preconception and antenatal health and health care aimed at preventing or delaying preterm birth may not be reaching all populations. PMID- 27687221 TI - Kinetic of orange pigment production from Monascus ruber on submerged fermentation. AB - Pigments produced by species of Monascus have been used to coloring rice, meat, sauces, wines and beers in East Asian countries. Monascus can produce orange (precursor), yellow and red pigments. Orange pigments have low solubility in culture media and when react with amino groups they become red and largely soluble. The orange pigments are an alternative to industrial pigment production because the low solubility facilitates the downstream operations. The aim of this work was to study the kinetic on the production of orange pigments by Monascus ruber CCT 3802. The shaking frequency of 300 rpm was favorable to production, whereas higher shaking frequencies showed negative effect. Pigment production was partially associated with cell growth, the critical dissolved oxygen concentration was between 0.894 and 1.388 mgO2 L-1 at 30 degrees C, and limiting conditions of dissolved oxygen decreased the production of orange pigments. The maintenance coefficient (mo) and the conversion factor of oxygen in biomass (Yo) were 18.603 mgO2 g x-1 h-1 and 3.133 gx gO 2-1 and the consideration of these parameters in the oxygen balance to estimate the biomass concentration provided good fits to the experimental data. PMID- 27687218 TI - Changes in brain oxysterols at different stages of Alzheimer's disease: Their involvement in neuroinflammation. AB - Alzheimer's disease (AD) is a gradually debilitating disease that leads to dementia. The molecular mechanisms underlying AD are still not clear, and at present no reliable biomarkers are available for the early diagnosis. In the last several years, together with oxidative stress and neuroinflammation, altered cholesterol metabolism in the brain has become increasingly implicated in AD progression. A significant body of evidence indicates that oxidized cholesterol, in the form of oxysterols, is one of the main triggers of AD. The oxysterols potentially most closely involved in the pathogenesis of AD are 24 hydroxycholesterol and 27-hydroxycholesterol, respectively deriving from cholesterol oxidation by the enzymes CYP46A1 and CYP27A1. However, the possible involvement of oxysterols resulting from cholesterol autooxidation, including 7 ketocholesterol and 7beta-hydroxycholesterol, is now emerging. In a systematic analysis of oxysterols in post-mortem human AD brains, classified by the Braak staging system of neurofibrillary pathology, alongside the two oxysterols of enzymatic origin, a variety of oxysterols deriving from cholesterol autoxidation were identified; these included 7-ketocholesterol, 7alpha-hydroxycholesterol, 4beta-hydroxycholesterol, 5alpha,6alpha-epoxycholesterol, and 5beta,6beta epoxycholesterol. Their levels were quantified and compared across the disease stages. Some inflammatory mediators, and the proteolytic enzyme matrix metalloprotease-9, were also found to be enhanced in the brains, depending on disease progression. This highlights the pathogenic association between the trends of inflammatory molecules and oxysterol levels during the evolution of AD. Conversely, sirtuin 1, an enzyme that regulates several pathways involved in the anti-inflammatory response, was reduced markedly with the progression of AD, supporting the hypothesis that the loss of sirtuin 1 might play a key role in AD. Taken together, these results strongly support the association between changes in oxysterol levels and AD progression. PMID- 27687222 TI - Dysfunctional Pain Modulation in Torture Survivors: The Mediating Effect of PTSD. AB - : Trauma survivors, and particularly torture survivors, suffer from high rates of chronic pain and posttraumatic stress disorder (PTSD) for years afterward, along with alterations in the function of the pain system. On the basis of longitudinal data on PTSD symptomatology, we tested whether exposure to torture, PTSD or PTSD trajectories accounted for chronic pain and altered pain perception. Participants were 59 torture survivors and 44 age-matched healthy control subjects. Chronic pain was characterized. Pain threshold, pain tolerance, conditioned pain modulation (CPM), and temporal summation of pain were measured. Three PTSD trajectories were identified among torture survivors; chronic, delayed, and resilient. Lack of CPM and more intense chronic pain was found among the chronic and delayed groups compared with the resilient and healthy control groups. Temporal summation of pain was strongest among the chronic group. PTSD trajectories mediated the relationship between torture and CPM. It appears that the duration and severity of posttraumatic distress, rather than the exposure to trauma, are crucial factors that mediate the association between trauma and chronic pain. Because PTSD and its resultant distress are measurable, their evaluation seems particularly important in the management of pain among trauma survivors. The results may be generalized to other instances in which chronic pain persists after traumatic events. PERSPECTIVE: This article presents the mediation effect of PTSD trajectory on pain modulation among trauma survivors suggesting that it is the duration and severity of PTSD/distress, rather than the exposure to trauma per se, that influence the perception and modulation of pain. PMID- 27687220 TI - Glutathione maintenance mitigates age-related susceptibility to redox cycling agents. AB - Isolated hepatocytes from young (4-6mo) and old (24-26mo) F344 rats were exposed to increasing concentrations of menadione, a vitamin K derivative and redox cycling agent, to determine whether the age-related decline in Nrf2-mediated detoxification defenses resulted in heightened susceptibility to xenobiotic insult. An LC50 for each age group was established, which showed that aging resulted in a nearly 2-fold increase in susceptibility to menadione (LC50 for young: 405MUM; LC50 for old: 275MUM). Examination of the known Nrf2-regulated pathways associated with menadione detoxification revealed, surprisingly, that NAD(P)H: quinone oxido-reductase 1 (NQO1) protein levels and activity were induced 9-fold and 4-fold with age, respectively (p=0.0019 and p=0.018; N=3), but glutathione peroxidase 4 (GPX4) declined by 70% (p=0.0043; N=3). These results indicate toxicity may stem from vulnerability to lipid peroxidation instead of inadequate reduction of menadione semi-quinone. Lipid peroxidation was 2-fold higher, and GSH declined by a 3-fold greater margin in old versus young rat cells given 300uM menadione (p<0.05 and p<=0.01 respectively; N=3). We therefore provided 400uMN-acetyl-cysteine (NAC) to hepatocytes from old rats before menadione exposure to alleviate limits in cysteine substrate availability for GSH synthesis during challenge. NAC pretreatment resulted in a >2-fold reduction in cell death, suggesting that the age-related increase in menadione susceptibility likely stems from attenuated GSH-dependent defenses. This data identifies cellular targets for intervention in order to limit age-related toxicological insults to menadione and potentially other redox cycling compounds. PMID- 27687219 TI - Resistance training and redox homeostasis: Correlation with age-associated genomic changes. AB - Regular physical activity is effective as prevention and treatment for different chronic conditions related to the ageing processes. In fact, a sedentary lifestyle has been linked to a worsening of cellular ageing biomarkers such as telomere length (TL) and/or specific epigenetic changes (e.g. DNA methylation), with increase of the propensity to aging-related diseases and premature death. Extending our previous findings, we aimed to test the hypothesis that 12 weeks of low frequency, moderate intensity, explosive-type resistance training (EMRT) may attenuate age-associated genomic changes. To this aim, TL, global DNA methylation, TRF2, Ku80, SIRT1, SIRT2 and global protein acetylation, as well as other proteins involved in apoptotic pathway (Bcl-2, Bax and Caspase-3), antioxidant response (TrxR1 and MnSOD) and oxidative damage (myeloperoxidase) were evaluated before and after EMRT in whole blood or peripheral mononuclear cells (PBMCs) of elderly subjects. Our findings confirm the potential of EMRT to induce an adaptive change in the antioxidant protein systems at systemic level and suggest a putative role of resistance training in the reduction of global DNA methylation. Moreover, we observed that EMRT counteracts the telomeres' shortening in a manner that proved to be directly correlated with the amelioration of redox homeostasis and efficacy of training regime, evaluated as improvement of both muscle's power/strength and functional parameters. PMID- 27687223 TI - Dorsal Root Ganglionic Field Stimulation Relieves Spontaneous and Induced Neuropathic Pain in Rats. AB - : Dorsal root ganglion (DRG) electrical stimulation (ganglionic field stimulation [GFS]) is effective in relieving clinical pain, but its mechanism is unknown. We therefore developed a rat model for GFS to test analgesic effects in the context of neuropathic pain. GFS was applied with a bipolar electrode at L4, using parameters replicating clinical use (20 Hz, 150-MUs pulse width, current at 80% of motor threshold). Neuropathic pain was generated by tibial nerve injury (TNI). Pain behavior was monitored by determining the threshold for withdrawal from punctate mechanical stimuli, by identifying hyperalgesic responses to noxious mechanical stimuli, and by hypersensitivity to cold. The affective dimension of pain was measured using conditioned place preference. We found that electrode insertion caused no behavioral evidence of pain and produced no histological evidence of DRG damage. GFS reversed TNI-induced hypersensitivity to cold and mechanical hyperalgesia and allodynia. Allodynia remained diminished 15 minutes after GFS. Conditioned place preference showed that GFS was not rewarding in uninjured control animals but was rewarding in animals subjected to TNI, which reveals analgesic efficacy of GFS for spontaneous pain. We conclude that GFS relieves neuropathic pain in rats. This model may provide a platform for identifying mechanisms and novel applications of GFS. PERSPECTIVE: We show that electrical stimulation of the DRG in rats reverses neuropathic pain behavior and provides a rewarding effect to animals with spontaneous neuropathic pain. This confirms analgesic efficacy of DRG stimulation in an animal model, and provides a platform for preclinical exploration. PMID- 27687224 TI - Real time observation and automated measurement of red blood cells agglutination inside a passive microfluidic biochip containing embedded reagents. AB - The process of agglutination is commonly used for the detection of biomarkers like proteins or viruses. The multiple bindings between micrometer sized particles, either latex beads or red blood cells (RBCs), create aggregates that are easily detectable and give qualitative information about the presence of the biomarkers. In most cases, the detection is made by simple naked-eye observation of agglutinates without any access to the kinetics of agglutination. In this study, we address the development of a real-time time observation of RBCs agglutination. Using ABO blood typing as a proof-of-concept, we developed i) an integrated biological protocol suitable for further use as point-of-care (POC) analysis and ii) two dedicated image processing algorithms for the real-time and quantitative measurement of agglutination. Anti-A or anti-B typing reagents were dried inside the microchannel of a passive microfluidic chip designed to enhance capillary flow. A blood drop deposit at the tip of the biochip established a simple biological protocol. In situ agglutination of autologous RBCs was achieved by means of embedded reagents and real time agglutination process was monitored by video recording. Using a training set of 24 experiments, two real-time indicators based on correlation and variance of gray levels were optimized and then further confirmed on a validation set. 100% correct discrimination between positive and negative agglutinations was performed within less than 2min by measuring real-time evolution of both correlation and variance indicators. PMID- 27687225 TI - Global transcriptional regulator TrmB family members in prokaryotes. AB - Members of the TrmB family act as global transcriptional regulators for the activation or repression of sugar ABC transporters and central sugar metabolic pathways, including glycolytic, gluconeogenic, and other metabolic pathways, and also as chromosomal stabilizers in archaea. As a relatively newly classified transcriptional regulator family, there is limited experimental evidence for their role in Thermococcales, halophilic archaeon Halobacterium salinarum NRC1, and crenarchaea Sulfolobus strains, despite being one of the extending protein families in archaea. Recently, the protein structures of Pyrococcus furiosus TrmB and TrmBL2 were solved, and the transcriptomic data uncovered by microarray and ChIP-Seq were published. In the present review, recent evidence of the functional roles of TrmB family members in archaea is explained and extended to bacteria. PMID- 27687226 TI - Diversity and enzyme activity of Penicillium species associated with macroalgae in Jeju Island. AB - A total of 28 strains of 19 Penicillium species were isolated in a survey of extracellular enzyme-producing fungi from macroalgae along the coast of Jeju Island of Korea. Penicillium species were identified based on morphological and beta-tubulin sequence analyses. In addition, the halo-tolerance and enzyme activity of all strains were evaluated. The diversity of Penicillium strains isolated from brown algae was higher than the diversity of strains isolated from green and red algae. The commonly isolated species were Penicillium antarcticum, P. bialowiezense, P. brevicompactum, P. crustosum, P. oxalicum, P. rubens, P. sumatrense, and P. terrigenum. While many strains showed endoglucanase, beta glucosidase, and protease activity, no alginase activity was detected. There was a positive correlation between halo-tolerance and endoglucanase activity within Penicillium species. Among 19 Penicillium species, three species-P. kongii, P. olsonii, and P. viticola-have not been previously recorded in Korea. PMID- 27687227 TI - Arcobacter acticola sp. nov., isolated from seawater on the East Sea in South Korea. AB - A Gram-stain-negative, facultative aerobic, non-flagellated, and rod-shaped bacterium, designated AR-13(T), was isolated from a seawater on the East Sea in South Korea, and subjected to a polyphasic taxonomic study. Strain AR-13(T) grew optimally at 30 degrees C, at pH 7.0-8.0 and in the presence of 0-0.5% (w/v) NaCl. The phylogenetic trees based on 16S rRNA gene sequences showed that strain AR-13(T) fell within the clade comprising the type strains of Arcobacter species, clustering coherently with the type strain of Arcobacter venerupis. Strain AR 13(T) exhibited 16S rRNA gene sequence similarity values of 98.1% to the type strain of A. venerupis and of 93.2-96.9% to the type strains of the other Arcobacter species. Strain AR-13(T) contained MK-6 as the only menaquinone and summed feature 3 (C16:1 omega7c and/or C16:1 omega6c), C16:0, C18:1 omega7c, and summed feature 2 (iso-C16:1 I and/or C14:0 3-OH) as the major fatty acids. The major polar lipids detected in strain AR-13(T) were phosphatidylethanolamine, phosphatidylglycerol, and one unidentified aminophospholipid. The DNA G+C content was 28.3 mol% and its mean DNA-DNA relatedness value with the type strain of A. venerupis was 21%. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain AR-13(T) is separated from recognized Arcobacter species. On the basis of the data presented, strain AR-13(T) is considered to represent a novel species of the genus Arcobacter, for which the name Arcobacter acticola sp. nov. is proposed. The type strain is AR-13(T) (=KCTC 52212(T) =NBRC 112272(T)).

AB - RraA is a protein inhibitor of RNase E (Rne), which catalyzes the endoribonucleolytic cleavage of a large proportion of RNAs in Escherichia coli. The antibiotic-producing bacterium Streptomyces coelicolor also contains homologs of RNase E and RraA, designated as RNase ES (Rns), RraAS1, and RraAS2, respectively. Here, we report that RraAS2 requires both scaffold domains of RNase ES for high-affinity binding and inhibitory action on the ribonucleolytic activity. Analyses of the steady-state level of RNase E substrates indicated that coexpression of RraAS2 in E. coli cells overproducing Rns effectively inhibits the ribonucleolytic activity of full-length RNase ES, but its inhibitory effects were moderate or undetectable on other truncated forms of Rns, in which the N- or/and C-terminal scaffold domain was deleted. In addition, RraAS2 more efficiently inhibited the in vitro ribonucleolytic activity of RNase ES than that of a truncated form containing the catalytic domain only. Coimmunoprecipitation and in vivo cross-linking experiments further showed necessity of both scaffold domains of RNase ES for high-affinity binding of RraAS2 to the enzyme, resulting in decreased RNA-binding capacity of RNase ES. Our results indicate that RraAS2 is a protein inhibitor of RNase ES and provide clues to how this inhibitor affects the ribonucleolytic activity of RNase ES. PMID- 27687229 TI - Functional analysis of recombinant human and Yarrowia lipolytica O-GlcNAc transferases expressed in Saccharomyces cerevisiae. AB - O-linked beta-N-acetylglucosamine (O-GlcNAc) glycosylation is an important post translational modification in many cellular processes. It is mediated by O-GlcNAc transferases (OGTs), which catalyze the addition of O-GlcNAc to serine or threonine residues of the target proteins. In this study, we expressed a putative Yarrowia lipolytica OGT (YlOGT), the only homolog identified in the subphylum Saccharomycotina through bioinformatics analysis, and the human OGT (hOGT) as recombinant proteins in Saccharomyces cerevisiae, and performed their functional characterization. Immunoblotting assays using antibody against O-GlcNAc revealed that recombinant hOGT (rhOGT), but not the recombinant YlOGT (rYlOGT), undergoes auto-O-GlcNAcylation in the heterologous host S. cerevisiae. Moreover, the rhOGT expressed in S. cerevisiae showed a catalytic activity during in vitro assays using casein kinase II substrates, whereas no such activity was obtained in rYlOGT. However, the chimeric human-Y. lipolytica OGT, carrying the human tetratricopeptide repeat (TPR) domain along with the Y. lipolytica catalytic domain (CTD), mediated the transfer of O-GlcNAc moiety during the in vitro assays. Although the overexpression of full-length OGTs inhibited the growth of S. cerevisiae, no such inhibition was obtained upon overexpression of only the CTD fragment, indicating the role of TPR domain in growth inhibition. This is the first report on the functional analysis of the fungal OGT, indicating that the Y. lipolytica OGT retains its catalytic activity, although the physiological role and substrates of YlOGT remain to be elucidated. PMID- 27687230 TI - Degradation and polymerization of monolignols by Abortiporus biennis, and induction of its degradation with a reducing agent. AB - This study was carried out to better understand the characteristic modification mechanisms of monolignols by enzyme system of Abortiporus biennis and to induce the degradation of monolignols. Degradation and polymerization of monolignols were simultaneously induced by A. biennis. Whole cells of A. biennis degraded coniferyl alcohol to vanillin and coniferyl aldehyde, and degraded sinapyl alcohol to 2,6-dimethoxybenzene- 1,4-diol, with the production of dimers. The molecular weight of monolignols treated with A. biennis increased drastically. The activities of lignin degrading enzymes were monitored for 24 h to determine whether there was any correlation between monolignol biomodification and ligninolytic enzymes. We concluded that complex enzyme systems were involved in the degradation and polymerization of monolignols. To degrade monolignols, ascorbic acid was added to the culture medium as a reducing agent. In the presence of ascorbic acid, the molecular weight was less increased in the case of coniferyl alcohol, while that of sinapyl alcohol was similar to that of the control. Furthermore, the addition of ascorbic acid led to the production of various degraded compounds: syringaldehyde and acid compounds. Accordingly, these results demonstrated that ascorbic acid prevented the rapid polymerization of monolignols, thus stabilizing radicals generated by enzymes of A. biennis. Thereafter, A. biennis catalyzed the oxidation of stable monolignols. As a result, ascorbic acid facilitated predominantly monolignols degradation by A. biennis through the stabilization of radicals. These findings showed outstanding ability of A. biennis to modify the lignin compounds rapidly and usefully. PMID- 27687231 TI - Molecular epidemiology of norovirus in asymptomatic food handlers in Busan, Korea, and emergence of genotype GII.17. AB - The molecular epidemiology of norovirus infections was studied in food handlers without any symptoms from January to December 2015 in Busan city, Korea. A total of 2,174 fecal specimens from asymptomatic food handlers were analyzed, and 2.3% (49/2,174) were norovirus-positive. Fourteen of 335 samples (4.2%) were positive in January; fifteen of 299 samples (5.0%) in February, and seven of 189 samples (3.7%) in December. However, norovirus was rarely detected in other months. From sequencing analysis, 11 genotypes (five GI and six GII genotypes) were detected. Among the 42 capid gene sequences identified, 14 were from the GI genogroup, while 28 were from the GII genogroup. The most commonly detected genotype was GII.17, comprising 15 (35.7%) of positive samples. From January 2012 to December 2015, 5,138 samples were collected from gastroenteritis patients and outbreaks in Busan. The most detected genotype in 2012, 2013, and 2014 was GII.4 (121, 24, and 12 cases, respectively), but in 2015, GII.17 (25 cases) was the most common. The GII.4 genotype was the major cause of acute gastroenteritis from 2012 to 2014, but the GII.17 genotype became the most prevalent cause in 2015. Continued epidemiological surveillance of GII.17 is needed, together with assessment of the risk of norovirus infection.

PMID- 27687232 TI - MDA7/IL-24 is an anti-viral factor that inhibits influenza virus replication. AB - Melanoma differentiation associated gene-7 (mda-7)/interleukin- 24 (IL-24) is a secreted cytokine, which plays an essential role in tumor suppression. Although its role as a multifunctional protein affecting broad types of cancers is well described, functions of IL-24 in host defense against virus infection are yet to be determined. In this study, we explored the anti-viral effect of recombinant IL 24 treatment during influenza infection. Infection of human lung adenocarcinoma cells (A549) with the influenza A virus up-regulated IL-24 mRNA and protein expression in a time-dependent manner. Pre-treatment of A549 cells with recombinant IL-24 protein effectively suppressed viral plaque formation. Furthermore, IL-24 treatment of A549 cells reduced viral non-structural protein 1 (NS1) synthesis, whereas IL-24 knockdown resulted in increased viral replication. Interestingly, IL-24 treatment following influenza A virus infection led to up regulation of interferon (IFN)-induced antiviral signaling. Taken together, our results suggest that IL-24 exerts a potent suppressive effect on influenza viral replication and can be used in the treatment of influenza infection. PMID- 27687234 TI - Finding the Right Treatment for Achalasia Treatment: Risks, Efficacy, Complications. AB - OPINION STATEMENT: Achalasia is a primary esophageal motor disorder of the esophagus that is characterized by the absence of esophageal peristalsis and a failure of the lower esophageal sphincter (LES) to relax upon swallowing. The defective relaxation leads to symptoms of dysphagia for solids and liquids, regurgitation, aspiration, chest pain, and weight loss. Achalasia is believed to result from a selective loss of enteric inhibitory neurons, most likely due to an autoimmune phenomenon in genetic susceptible individuals. As there is no curative treatment for achalasia, treatment is confined to disruption of the LES to improve bolus passage. The two most commonly used treatment modalities available are the endoscopic pneumodilation (PD) and the surgical laparoscopic Heller myotomy (LHM). A recent European randomized controlled trial showed that both treatment modalities have comparable success rates after a follow-up of at least 5 years. In view of these data, both treatments can be used as an initial therapy in achalasia and the choice should be based on the expertise available. Recently, a new endoscopic technique, peroral endoscopic myotomy (POEM), has been introduced with excellent short-term success rates. However, longer follow-up and data from randomized controlled trials are needed before accepting this technique as a new treatment option for achalasia in clinical practice. PMID- 27687235 TI - Design and application of a tool for structuring, capitalizing and making more accessible information and lessons learned from accidents involving machinery. AB - Accident reports are published in order to communicate the information and lessons learned from accidents. An efficient accident recording and analysis system is a necessary step towards improvement of safety. However, currently there is a shortage of efficient tools to support such recording and analysis. In this study we introduce a flexible and customizable tool that allows structuring and analysis of this information. This tool has been implemented under TEEXMA(r). We named our prototype TEEXMA(r)SAFETY. This tool provides an information management system to facilitate data collection, organization, query, analysis and reporting of accidents. A predefined information retrieval module provides ready access to data which allows the user to quickly identify the possible hazards for specific machines and provides information on the source of hazards. The main target audience for this tool includes safety personnel, accident reporters and designers. The proposed data model has been developed by analyzing different accident reports. PMID- 27687236 TI - Distribution of microRNA biomarker candidates in solid tissues and body fluids. AB - Small non-coding RNAs, especially microRNAs, are discussed as promising biomarkers for a substantial number of human pathologies. A broad understanding in which solid tissues, cell types or body fluids a microRNA is expressed helps also to understand and to improve the suitability of miRNAs as non- or minimally invasive disease markers. We recently reported the Human miRNA Tissue Atlas ( http://www.ccb.uni-saarland.de/tissueatlas ) containing 105 miRNA profiles of 31 organs from 2 corpses. We subsequently added miRNA profiles measured by others and us using the same array technology as for the first version of the Human miRNA Tissue Atlas. The latter profiles stem from 163 solid organs including lung, prostate and gastric tissue, from 253 whole blood samples and 66 fractioned blood cell isolates, from body fluids including 72 serum samples, 278 plasma samples, 29 urine samples, and 16 saliva samples and from different collection and storage conditions. While most miRNAs are ubiquitous abundant in solid tissues and whole blood, we also identified miRNAs that are rather specific for tissues. Our web-based repository now hosting 982 full miRNomes all of which are measured by the same microarray technology. The knowledge of these variant abundances of miRNAs in solid tissues, in whole blood and in other body fluids is essential to judge the value of miRNAs as biomarker.

A systematic review on the effects of surgical and pharmacological treatments for endometriosis on female sexual functioning. AB - INTRODUCTION: Endometriosis is associated with an increased risk of dyspareunia, therefore this chronic gynecologic disease should be considered as a major cause of sexual dysfunctions. The aims of this study were to review the literature on the effects of surgical and pharmacological treatments for endometriosis on female sexual functioning, and to provide suggestions for future treatment strategies. MATERIAL AND METHODS: We followed the PRISMA guidelines to conduct this systematic review, which involved an electronic database search of studies on the association between endometriosis and sexuality published between 2000 and 2016. RESULTS: As a result of the screening process, 22 studies were included in this systematic review. The 22 studies included were divided into two categories: (a) surgical intervention studies (n = 17), examining postoperative sexual outcomes of surgery for endometriosis; (b) pharmacological intervention studies (n = 5), evaluating the effects of pharmacological endometriosis treatments on sexual functioning. The studies considered showed that overall surgical and pharmacological interventions for endometriosis can lead to medium-/long-term improvement, but not necessarily to a definitive resolution of female sexual dysfunctions due to endometriosis. CONCLUSIONS: Sexual functioning is a multidimensional phenomenon and the ideal treatment for endometriosis-related sexual dysfunctions should be conducted by a multidisciplinary team that involves not only gynecologists, but also sexologists and psychologists/psychotherapists. Improving global sexual functioning, and not just reducing pain at intercourse, should be considered as a major clinical goal of endometriosis treatment. PMID- 27687242 TI - Sociocultural factors contributing to teenage pregnancy in Zomba district, Malawi. AB - This study explores sociocultural and other risk factors associated with unplanned teenage pregnancy in Zomba district of Malawi. Data were obtained from 505 participants under the age of 20 years using a questionnaire administered through face-to-face interviews held at five antenatal clinics. The data were analysed using descriptive statistics, frequency tables and chi-square analysis which allowed comparative understanding of the sociocultural risk factors for planned and unplanned teenage pregnancy in Zomba district. The findings revealed that teenage pregnancy is a major health and social problem. Over 76% of the teenage respondents in the study had experienced unplanned pregnancy. Among the prominent factors that stood out in the analysis for this high rate of teenage pregnancy were early sex and marriage, low contraceptive use, low educational levels, low socio-economic status, lack of knowledge of reproductive and sexual health, gender inequity, and physical/sexual violence. The consequences on teenage mothers of unplanned pregnancy have been tragic and have compromised their physical, psychological and socioeconomic wellbeing, not just on them but also their families and society at large. The findings point to the need for a multi-sectoral approach to tackle the problem on teenage pregnancy in this district, and likely throughout Malawi. PMID- 27687241 TI - The role of mitogen-activated protein kinases and sterol receptor coactivator-1 in TGF-beta-regulated expression of genes implicated in macrophage cholesterol uptake. AB - The anti-atherogenic cytokine TGF-beta inhibits macrophage foam cell formation by suppressing the expression of key genes implicated in the uptake of modified lipoproteins. We have previously shown a critical role for p38 MAPK and JNK in the TGF-beta-mediated regulation of apolipoprotein E expression in human monocytes. However, the roles of these two MAPK pathways in the control of expression of key genes involved in the uptake of modified lipoproteins in human macrophages is poorly understood and formed the focus of this study. TGF-beta activated both p38 MAPK and JNK, and knockdown of p38 MAPK or c-Jun, a key downstream target of JNK action, demonstrated their requirement in the TGF-beta inhibited expression of several key genes implicated in macrophage lipoprotein uptake. The potential role of c-Jun and specific co-activators in the action of TGF-beta was investigated further by studies on the lipoprotein lipase gene. c Jun did not directly interact with the minimal promoter region containing the TGF beta response elements and a combination of transient transfection and knock down assays revealed an important role for SRC-1. These studies provide novel insights into the mechanisms underlying the TGF-beta-mediated inhibition of macrophage gene expression associated with the control of cholesterol homeostasis. PMID- 27687243 TI - Measuring maternal mortality using a Reproductive Age Mortality Study (RAMOS). AB - BACKGROUND: Assessing the feasibility of conducting a prospective Reproductive Age Mortality Survey (RAMOS) study in the low-income setting of Mangochi District, Malawi to obtain cotemporaneous estimates of the number, cause of and conditions associated with maternal deaths (MD) in all women of reproductive age (WRA) (n = 207 688). METHODS: MD among all deaths of WRA were identified using the ICD-10 definition. Cause of death and contributing conditions identified by a panel of experts using the classification system for deaths during pregnancy, childbirth and puerperium (ICD-MM). RESULTS: Out of 424 deaths of WRA, 151 were MD giving a Maternal Mortality Ratio (MMR) of 363 per 100,000 live births (95 % CI: 307-425). Only 86 MD had been reported via existing reporting mechanisms representing an underreporting of 43 %. The majority of MD (62.3 %) occurred in a health facility and were the result of direct obstetric causes (74.8 %) with obstetric haemorrhage as the leading cause (35.8 %), followed by pregnancy related infections (19.4 %), hypertensive disorders (16.8 %) and pregnancy with abortive outcome (13.2 %). Malaria was the most frequently identified indirect cause (9.9 %). Contributing conditions were more frequently identified when both verbal autopsy and facility-based death review had taken place and included obstructed labour (28.5 %), anaemia (12.6 %) and positive HIV status (4.0 %). CONCLUSION: The high number of MD that occur at health facility level, cause of death and contributing conditions reflect deficiencies in the quality of care at health facility level. A RAMOS is feasible in low- and middle-income settings and provides contemporaneous estimates of MMR. PMID- 27687244 TI - Adaptive pattern of nectar volume within inflorescences: bumblebee foraging behavior and pollinator-mediated natural selection. AB - Larger floral displays increase pollinator visitation as well as among-flower self-pollination (geitonogamy) in self-compatible species. Dichogamy (temporal separation of gender expression) can limit geitonogamy and increase outcrossing but this depends on pollinator behavior within inflorescences. Declining nectar volume from lower to upper flowers is a hypothesized adaptation to increase outcrossing and pollen export by encouraging the upward movment of pollinators from female to male flowers and by reducing the number of flowers probed per inflorescence, but supporting evidence has been equivocal. We tested this hypothesis in Aconitum gymnandrum by studying floral display and rewards, pollinator visitation, and pollinator-mediated selection on floral traits. We found that larger inflorescences of A. gymnandrum attracted more pollinators, but did not increase the number of flowers probed per visit. Nectar production declined with increasing flower height on average, but the opposite pattern was also common. Bumblebees responded strongly to the nectar pattern, moving from higher to lower nectar concentration. Finally, there was significant pollinator mediated direct selection for this pattern of declining nectar volume after correcting for correlations with flower size, number, and mean nectar volume. Together, the results strongly suggest that declining nectar production in higher flowers is an adaptation to enhance outcrossing in A. gymnandrum. PMID- 27687245 TI - Chemotaxis towards autoinducer 2 mediates autoaggregation in Escherichia coli. AB - Bacteria communicate by producing and sensing extracellular signal molecules called autoinducers. Such intercellular signalling, known as quorum sensing, allows bacteria to coordinate and synchronize behavioural responses at high cell densities. Autoinducer 2 (AI-2) is the only known quorum-sensing molecule produced by Escherichia coli but its physiological role remains elusive, although it is known to regulate biofilm formation and virulence in other bacterial species. Here we show that chemotaxis towards self-produced AI-2 can mediate collective behaviour-autoaggregation-of E. coli. Autoaggregation requires motility and is strongly enhanced by chemotaxis to AI-2 at physiological cell densities. These effects are observed regardless whether cell-cell interactions under particular growth conditions are mediated by the major E. coli adhesin (antigen 43) or by curli fibres. Furthermore, AI-2-dependent autoaggregation enhances bacterial stress resistance and promotes biofilm formation. PMID- 27687246 TI - Europium (III) Organic Complexes in Porous Boron Nitride Microfibers: Efficient Hybrid Luminescent Material. AB - We report the design and synthesis of a novel kind of organic-inorganic hybrid material via the incorporation of europium (III) beta-diketonate complexes (Eu(TTA)3, TTA = 2-thenoyltrifluoroacetone) into one-dimensional (1D) porous boron nitride (BN) microfibers. The developed Eu(TTA)3@BN hybrid composites with typical 1D fibrous morphology exhibit bright visible red-light emission on UV illumination. The confinement of Eu(TTA)3 within pores of BN microfibers not only decreases the aggregation-caused quenching in solid Eu(TTA)3, but also improves their thermal stabilities. Moreover, The strong interactions between Eu(TTA)3 and porous BN matrix result in an interesting energy transfer process from BN host to TTA ligand and TTA ligand to Eu3+ ions, leading to the remarkable increase of red emission. The synthetic approach should be a very promising strategy which can be easily expanded to other hybrid luminescent materials based on porous BN.

PMID- 27687249 TI - Dichotomy of cellular inhibition by small-molecule inhibitors revealed by single cell analysis. AB - Despite progress in drug development, a quantitative and physiological understanding of how small-molecule inhibitors act on cells is lacking. Here, we measure the signalling and proliferative response of individual primary T lymphocytes to a combination of antigen, cytokine and drug. We uncover two distinct modes of signalling inhibition: digital inhibition (the activated fraction of cells diminishes upon drug treatment, but active cells appear unperturbed), versus analogue inhibition (the activated fraction is unperturbed whereas activation response is diminished). We introduce a computational model of the signalling cascade that accounts for such inhibition dichotomy, and test the model predictions for the phenotypic variability of cellular responses. Finally, we demonstrate that the digital/analogue dichotomy of cellular response as revealed on short (signal transduction) timescales, translates into similar dichotomy on longer (proliferation) timescales. Our single-cell analysis of drug action illustrates the strength of quantitative approaches to translate in vitro pharmacology into functionally relevant cellular settings. PMID- 27687248 TI - Low expression of galectin-3 is associated with poor survival in node-positive breast cancers and mesenchymal phenotype in breast cancer stem cells. AB - BACKGROUND: Galectin-3 (Gal3) plays diverse roles in cancer initiation, progression, and drug resistance depending on tumor type characteristics that are also associated with cancer stem cells (CSCs). Recurrence of breast carcinomas may be attributed to the presence of breast CSCs (BCSCs). BCSCs exist in mesenchymal-like or epithelial-like states and the transition between these states endows BCSCs with the capacity for tumor progression. The discovery of a feedback loop with galectins during epithelial-to-mesenchymal transition (EMT) prompted us to investigate its role in breast cancer stemness. METHOD: To elucidate the role of Gal3 in BCSCs, we performed various in vitro and in vivo studies such as sphere-formation assays, Western blotting, flow cytometric apoptosis assays, and limited dilution xenotransplant models. Histological staining for Gal3 in tissue microarrays of breast cancer patients was performed to analyze the relationship of clinical outcome and Gal3 expression. RESULTS: Here, we show in a cohort of 87 node-positive breast cancer patients treated with doxorubicin-based chemotherapy that low Gal3 was associated with increased lymphovascular invasion and reduced overall survival. Analysis of in vitro BCSC models demonstrated that Gal3 knockdown by small hairpin RNA (shRNA) interference in epithelial-like mammary spheres leads to EMT, increased sphere-formation ability, drug-resistance, and heightened aldefluor activity. Furthermore, Gal3negative BCSCs were associated with enhanced tumorigenicity in orthotopic mouse models. CONCLUSIONS: Thus, in at least some breast cancers, loss of Gal3 might be associated with EMT and cancer stemness-associated traits, predicts poor response to chemotherapy, and poor prognosis. PMID- 27687251 TI - Fully automated structural MRI of the brain in clinical dementia workup. AB - Background The dementia syndrome has been regarded a clinical diagnosis but the focus on supplemental biomarkers is increasing. An automatic magnetic resonance imaging (MRI) volumetry method, NeuroQuant(r) (NQ), has been developed for use in clinical settings. Purpose To evaluate the clinical usefulness of NQ in distinguishing Alzheimer's disease dementia (AD) from non-dementia and non-AD dementia. Material and Methods NQ was performed in 275 patients diagnosed according to the criteria of ICD-10 for AD, vascular dementia and Parkinson's disease dementia (PDD); the Winblad criteria for mild cognitive impairment; the Lund-Manchester criteria for frontotemporal dementia; and the revised consensus criteria for Lewy body dementia (LBD). Receiver operating curve (ROC) analyses with calculation of area under the curve (AUC) and regression analyses were carried out. Results Forebrain parenchyma (AUC 0.82), hippocampus (AUC 0.80), and inferior lateral ventricles (AUC 0.78) yielded the highest AUCs for AD/non dementia discrimination. Only hippocampus (AUC 0.62) and cerebellum (AUC 0.67) separated AD from non-AD dementia. Cerebellum separated AD from PDD-LBD (AUC 0.83). Separate multiple regression analyses adjusted for age and gender, showed that memory (CERAD 10-word delayed recall) (beta 0.502, P < 0.001) was more strongly associated to the hippocampus volume than the diagnostic distinction of AD versus non-dementia (beta -0.392, P < 0.001). Conclusion NQ measures could separate AD from non-dementia fairly well but generally poorer from non-AD dementia. Degree of memory impairment, age, and gender, but not diagnostic distinction, were associated to the hippocampus volume in adjusted analyses. Surprisingly, cerebellum was found relevant in separating AD from PDD-LBD.

AB - In this study, we have employed graphene oxide as a matrix to simultaneously and directly quantify serum nonesterified and esterified fatty acids (FAs) using matrix-assisted laser/desorption ionization-Fourier transform ion cyclotron resonance mass spectrometry (MALDI-FTICR MS). Twelve serum nonesterified FAs combined with their individual esterified FAs (i.e., C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C20:2, C20:3, C20:4, C20:5, C22:5, and C22:6) were quantified based on their calibration curves with the correlation coefficients of >0.99, along with the analytical time of <1 min each sample. As a result, serum levels of twelve total FAs (TFAs) in 1440 serum samples from 487 healthy controls (HCs), 479 patients with benign lung diseases (BLDs) and 474 patients with lung cancer (LC) were determined. Statistical analysis indicated that significantly increased levels of C16:0, C16:1, C18:0, C18:1, C18:3, C20:3, and C22:6 and decreased levels of C20:5 were observed in LC patients compared with BLDs. Receiver operating characteristic (ROC) analysis revealed that panel a (C18:2, C20:3, C20:4, C20:5, C22:5, and C22:6), panel b (C18:0, C20:4, C20:5, and C22:6), and panel c (C16:1, C18:0, C18:1, C20:3, and C22:6) have exhibited good diagnostic ability to differentiate BLDs from LC relative to clinical uses of tumor markers (CEA and Cyfra 21-1).

AB - Background Self-expandable metallic stent (SEMS) placement is a well-established palliative treatment approach for malignant gastroduodenal obstruction. In patients with a long (>10 cm) stricture, multiple stents placed in an overlapping fashion are often required. Purpose To investigate the outcomes of overlapping SEMS placement for the palliative treatment of malignant gastroduodenal obstruction in patients with a long (>10 cm) stricture. Material and Methods The medical records of 40 patients who underwent fluoroscopic overlapping SEMS placement for malignant gastroduodenal obstruction due to a long (>10 cm) stricture were reviewed. Results The technical and clinical success rates were 100% and 65.0%, respectively. The mean length of the stricture was 17.0 +/- 4.7 cm and the mean number of stents placed in each patient was 2.2 +/- 0.5. Metastatic cancer (odds ratio [OR], 0.315; P = 0.018), Eastern Cooperative Oncology Group (ECOG) score >=3 (OR, 0.018; P = 0.006), and carcinomatosis with ascites (OR, 0.025; P = 0.017) were independent predictors of poor clinical success. The rates of minor and major complications were 27.5% and 2.5%, respectively. The median stent patency and survival were 33 days (interquartile range [IQR], 19-60 days) and 35 days (IQR, 19-73 days), respectively. An ECOG score >=3 was an independent predictor of a poor survival outcome (hazard ratio, 4.681; P < 0.001). Conclusion Overlapping SEMS placement may be safe and effective for the palliative treatment of malignant gastroduodenal obstruction in patients with a long (>10 cm) stricture.

AB - BACKGROUND: We investigated whether polymorphism rs7555523 (A > C) in human transmembrane and coiled-coil domain 1 (TMCO1) gene is a risk factor for primary open angle glaucoma (POAG) in a Saudi cohort. METHODS: A cohort of 87 unrelated POAG cases and 94 control subjects from Saudi Arabia were genotyped using Taq Man(r) assay. The association of genotypes with POAG and other glaucoma specific clinical indices was investigated. RESULTS: The genotype and allele frequency of polymorphism rs7555523 at TMCO1 did not show any statistically significant association with POAG as compared to controls. The minor allele frequency was 0.103 in cases and 0.085 in controls. Except for awareness of glaucoma (p = 0.036), no significant association of genotypes were seen with glaucoma specific clinical indices such as intraocular pressure (IOP), cup/disc ratio and number of anti-glaucoma medications used. Binary logistic regression analysis (adjusted for age and gender) showed that age was a significant indicator for the development of glaucoma in this group (adjusted odds ratio = 1.2; 95 % confidence interval = 1.078-1.157; p < 0.001). CONCLUSION: Our study was unable to replicate the findings of previously reported association for polymorphism rs7555523 in TMCO1 with POAG and related clinical indices such as IOP and cup/disc ratio indicating that this variant is not a risk factor for POAG in the Saudi cohort.

AB - Integrins are cell surface receptors that bind cells to their physical external environment, linking the extracellular matrix to cell function. They are essential in the biology of all animals. In the late 1980s, we discovered that integrins are required for the ability of breast epithelia to do what they are programmed to do, which is to differentiate and make milk. Since then, integrins have been shown to control most other aspects of phenotype: to stay alive, to divide, and to move about. Integrins also provide part of the mechanism that allows cells to form tissues. Here I discuss how we discovered that integrins control mammary gland differentiation and explore the role of integrins as central architects of other aspects of cell behavior.

Hartley (Rutaceae) is an endemic species to Madagascar. The chemical composition of leaf essential oil is reported for the first time. A sample was extracted by hydrodistillation and analysis was carried out by combination of chromatographic (GC), spectroscopic and spectrometric (MS, 13C NMR) techniques. In total, 56 compounds have been identified. The chemical composition was dominated by alpha-pinene (42.6%) followed by linalool (6.2%) and (E)-beta-caryophyllene (5.2%). PMID- 27687257 TI - Topoisomerases: Resistance versus Sensitivity, How Far We Can Go? AB - DNA topoisomerases are ubiquitously present remarkable molecular machines that help in altering topology of DNA in living cells. The crucial role played by these nucleases during DNA replication, transcription, and recombination vis-a vis less sequence similarity among different species makes topoisomerases unique and attractive targets for different anticancer and antibacterial drugs. However, druggability of topoisomerases by the existing class of molecules is increasingly becoming questationable due to resistance development predominated by mutations in the corresponding genes. The current scenario facing a decline in the development of new molecules further comprises an important factor that may challenge topoisomerase-targeting therapy. Thus, it is imperative to wisely use the existing inhibitors lest with this rapid rate of losing grip over the target we may not go too far. Furthermore, it is important not only to design new molecules but also to develop new approaches that may avoid obstacles in therapies due to multiple resistance mechanisms. This review provides a succinct account of different classes of topoisomerase inhibitors, focuses on resistance acquired by mutations in topoisomerases, and discusses the various approaches to increase the efficacy of topoisomerase inhibitors. In a later section, we also suggest the possibility of using bisbenzimidazoles along with efflux pump inhibitors for synergistic bactericidal effects.

PMID- 27687259 TI - Spontaneous pneumothorax in paracoccidioidomycosis patients from an endemic area in Midwestern Brazil. AB - Paracoccidioidomycosis (PCM) is the most important systemic mycosis in Latin America. About 80% of PCM patients are present with its chronic form. The lungs are affected in most patients with the chronic form; however, pleural involvement has rarely been reported. We describe nine cases of PCM that presented with lung involvement and spontaneous pneumothorax. All patients, except one whose condition was not investigated, were smokers. PCM was diagnosed during the pneumothorax episode in three patients, and from 3 to 16 years before the pneumothorax episode in six patients. A total of six patients underwent chest drainage and one died as a direct result of the pneumothorax. We suggest that pneumothorax, although rare, should be considered in PCM patients who present with suddenly worsening dyspnoea. PCM should also be investigated in cases of pneumothorax in adult men from mycosis-endemic areas. PMID- 27687265 TI - Looking out and looking in at BVA Members' Day.

AB - BACKGROUND: Trained medical interpreters are instrumental to patient satisfaction and quality of care. They are especially important in student-run clinics, where many patients have limited English proficiency. Because student-run clinics have ties to their medical schools, they have access to bilingual students who may volunteer to interpret, but are not necessarily formally trained. METHODS: To study the feasibility and efficacy of leveraging medical student volunteers to improve interpretation services, we performed a pilot study at the student-run clinic at the Icahn School of Medicine at Mount Sinai. In each fall semester in 2012-2015, we implemented a 6-h course providing didactic and interactive training on medical Spanish interpreting techniques and language skills to bilingual students. We then assessed the impact of the course on interpreter abilities. RESULTS: Participants' comfort levels, understanding of their roles, and understanding of terminology significantly increased after the course (p < 0.05), and these gains remained several months later (p < 0.05) and were repeated in an independent cohort. Patients and student clinicians also rated participants highly (averages above 4.5 out of 5) on these measures in real clinical encounters. CONCLUSIONS: These findings suggest that a formal interpreter training course tailored for medical students in the setting of a student-run clinic is feasible and effective. This program for training qualified student interpreters can serve as a model for other settings where medical students serve as interpreters. PMID- 27687286 TI - Distribution and Diversity of Microbial Eukaryotes in Bathypelagic Waters of the South China Sea. AB - Little is known about the biodiversity of microbial eukaryotes in the South China Sea, especially in waters at bathyal depths. Here, we employed SSU rDNA gene sequencing to reveal the diversity and community structure across depth and distance gradients in the South China Sea. Vertically, the highest alpha diversity was found at 75-m depth. The communities of microbial eukaryotes were clustered into shallow-, middle-, and deep-water groups according to the depth from which they were collected, indicating a depth-related diversity and distribution pattern. Rhizaria sequences dominated the microeukaryote community and occurred in all samples except those from less than 50-m deep, being most abundant near the sea floor where they contributed ca. 64-97% and 40-74% of the total sequences and OTUs recovered, respectively. A large portion of rhizarian OTUs has neither a nearest named neighbor nor a nearest neighbor in the GenBank database which indicated the presence of new phylotypes in the South China Sea. Given their overwhelming abundance and richness, further phylogenetic analysis of rhizarians were performed and three new genetic clusters were revealed containing sequences retrieved from the deep waters of the South China Sea. Our results shed light on the diversity and community structure of microbial eukaryotes in this not yet fully explored area. PMID- 27687287 TI - Taking OSCE examiner training on the road: reaching the masses. AB - BACKGROUND: To ensure the rigour of objective structured clinical examinations (OSCEs) in assessing medical students, medical school educators must educate examiners with a view to standardising examiner assessment behaviour. Delivering OSCE examiner training is a necessary yet challenging part of the OSCE process. A novel approach to implementing training for current and potential OSCE examiners was trialled by delivering large-group education sessions at major teaching hospitals. METHODS: The 'OSCE Roadshow' comprised a short training session delivered in the context of teaching hospital 'Grand Rounds' to current and potential OSCE examiners. The training was developed to educate clinicians about OSCE processes, clarify the examiners' role and required behaviours, and to review marking guides and mark allocation in an effort to standardise OSCE processes and encourage consistency in examiner marking behaviour. A short exercise allowed participants to practise marking a mock OSCE to investigate examiner marking behaviour after the training. RESULTS: OSCE Roadshows at four metropolitan and one rural teaching hospital were well received and well attended by 171 clinicians across six sessions. Unexpectedly, medical students also attended in large numbers (n=220). After training, participants' average scores for the mock OSCE clustered closely around the ideal score of 28 (out of 40), and the average scores did not differ according to the levels of clinical experience. CONCLUSION: The OSCE Roadshow demonstrated the potential of brief familiarisation training in reaching large numbers of current and potential OSCE examiners in a time and cost-effective manner to promote standardisation of OSCE processes.

AB - In order to improve the conservation and sustainable utilization of the African catfish Clarias gariepinus of the Yala Swamp in Kenya, genetic diversity and population structure of Lakes Kanyaboli and Namboyo populations of the species were studied using DNA sequences of the mitochondrial D-loop control region. Genetic diversity inferred as haplotype and nucleotide diversities and number of singletons and shared haplotypes was higher in the Lake Kanyaboli population (LKG) than the Lake Namboyo population (LNG) of C. gariepinus. Thirty-one haplotypes were inferred, of which 25 (80.6%) were private or singletons, while only six (19.4%) haplotypes were shared between LKG and LNG. Both populations were differentiated, with FST value that was significantly different from zero (P < 0.05). Two clusters were inferred both from the maximum likelihood tree and the spanning networks of phylogenetic relationships of haplotypes. Mismatch distribution for total sample was multi-modal but individually, distributions were uni-modal in LKG, but multimodal in LNG. The mean +/- s.d. raggedness index for both populations was 0.085 +/- 0.098 and not significantly different from zero (P > 0.05). Individual raggedness indices were 0.015 and 0.154 for LKG and LNG respectively. Fu's Fs was negative for both populations, with LKG recording 14.871, while LNG had -2.565, significantly different from zero for LKG (P < 0.05), but the value for LNG was not significant (P > 0.05). Tajima's D was negative for both populations, with LKG recording -1.734, while LNG had -1.136. Standardized square differences (SSD) were 0.001 for LKG and 0.048 for LNG and non-significant between them (P > 0.05). Values between all populations were also not significantly different (P > 0.05), mean +/- s.d. SSD 0.025 +/- 0.033. PMID- 27687289 TI - Progression of motor neuron disease is accelerated and the ability to recover is compromised with advanced age in rNLS8 mice. AB - In order to treat progressive paralysis in ALS patients, it is critical to develop a mouse that closely models human ALS in both pathology and also in the timing of these events. We have recently generated new TDP-43 bigenic mice (called rNLS8) with doxycycline (Dox)-suppressible expression of human TDP-43 (hTDP-43) harboring a defective nuclear localization signal (hTDP-43?NLS) under the control of the NEFH promoter. Our previous studies characterized the pathology and disease course in young rNLS8 mice following induction of neuronal hTDP-43DeltaNLS. We now seek to examine if the order and timing of pathologic events are changed in aged mice. We found that the expression of hTDP-43?NLS in 12+ month old mice did not accelerate the appearance of neuromuscular abnormalities or motor neuron (MN) death in the lumbar spinal cord (SC), though disease progression was accelerated. However, following suppression of the transgene, important differences between young and aged rNLS8 mice emerged in functional motor recovery. We found that recovery was incomplete in aged mice relative to their younger treatment matched counterparts based on gross behavioral measures and physiological recordings from the animals' gastrocnemius (GC) muscles, despite muscle reinnervation by surviving MNs. This is likely because the reinnervation most often only resulted in partial nerve and endplate connections and the muscle's junctional folds were much more disorganized in aged rNLS8 mice. We believe that these studies will be an important basis for the future design and evaluation of therapies designed to slow denervation and promote re-innervation in adult ALS patients. PMID- 27687290 TI - Calendaring and alarms can improve naturalistic time-based prospective memory for youth infected with HIV. AB - Individuals with HIV disease often evidence deficits in prospective memory (PM), which interfere with daily functioning and increase the risk of suboptimal health behaviours. This study examined the benefits of simple encoding and cueing supports on naturalistic time-based PM in 47 HIV-positive young adults. All participants completed a naturalistic time-based PM task in which they were instructed to text the examiner once per day for seven days at a specified time. Participants were randomised into (1) a Calendaring condition in which they created a calendar event in their mobile telephone for the specified texting time; (2) an Alarm condition in which they programmed an alarm into their mobile telephone for the specified texting time; (3) a Combined calendaring and alarm condition; and (4) a Control condition. Participants in the Combined condition demonstrated significantly better naturalistic PM performance than participants in the Control and Calendaring conditions. Findings indicate that HIV-positive young people may benefit from a combined calendaring and alarm supportive strategy for successful execution of future intentions in daily life. PMID- 27687292 TI - Decision-making in rectal and colorectal cancer: systematic review and qualitative analysis of surgeons' preferences. AB - Surgeons are experiencing difficulties implementing recommendations not only owing to incomplete, confusing or conflicting information but also to the increasing involvement of patients in decisions relating to their health. This study sought to establish which common factors including heuristic factors guide surgeons' decision-making in colon and rectal cancers. We conducted a systematic literature review of surgeons' decision-making factors related to colon and rectal cancer treatment. Eleven of 349 identified publications were eligible for data analyses. Using the IRaMuTeQ (Interface of R for the Multidimensional Analyses of Texts and Questionnaire), we carried out a qualitative analysis of the significant factors collected in the studies reviewed. Several validation procedures were applied to control the robustness of the findings. Five categories of factors (i.e. patient, surgeon, treatment, tumor and organizational cues) were found to influence surgeons' decision-making. Specifically, all decision criteria including biomedical (e.g. tumor information) and heuristic (e.g. surgeons' dispositional factors) criteria converged towards the factor 'age of patient' in the similarity analysis. In the light of the results, we propose an explanatory model showing the impact of heuristic criteria on medical issues (i.e. diagnosis, prognosis, treatment features, etc.) and thus on decision making. Finally, the psychosocial complexity involved in decision-making is discussed and a medico-psycho-social grid for use in multidisciplinary meetings is proposed. PMID- 27687291 TI - Transcriptomic regulations in oligodendroglial and microglial cells related to brain damage following fetal growth restriction. AB - Fetal growth restriction (FGR) is a major complication of human pregnancy, frequently resulting from placental vascular diseases and prenatal malnutrition, and is associated with adverse neurocognitive outcomes throughout life. However, the mechanisms linking poor fetal growth and neurocognitive impairment are unclear. Here, we aimed to correlate changes in gene expression induced by FGR in rats and abnormal cerebral white matter maturation, brain microstructure, and cortical connectivity in vivo. We investigated a model of FGR induced by low protein-diet malnutrition between embryonic day 0 and birth using an interdisciplinary approach combining advanced brain imaging, in vivo connectivity, microarray analysis of sorted oligodendroglial and microglial cells and histology. We show that myelination and brain function are both significantly altered in our model of FGR. These alterations, detected first in the white matter on magnetic resonance imaging significantly reduced cortical connectivity as assessed by ultrafast ultrasound imaging. Fetal growth retardation was found associated with white matter dysmaturation as shown by the immunohistochemical profiles and microarrays analyses. Strikingly, transcriptomic and gene network analyses reveal not only a myelination deficit in growth-restricted pups, but also the extensive deregulation of genes controlling neuroinflammation and the cell cycle in both oligodendrocytes and microglia. Our findings shed new light on the cellular and gene regulatory mechanisms mediating brain structural and functional defects in malnutrition-induced FGR, and suggest, for the first time, a neuroinflammatory basis for the poor neurocognitive outcome observed in growth restricted human infants.

AB - The reduction in intraoral pressure during swallowing has previously been linked to bolus transport, although no such relation has yet been proven. The purpose of this work was to evaluate the time course of intraoral pressure during swallowing using simultaneous real-time magnetic resonance imaging (MRI) and dynamic pressure recordings. Real-time MRI based on highly undersampled radial fast low angle shot (FLASH) and regularized nonlinear inverse reconstruction was performed at 3 T using a standard head coil and a mid-sagittal section covering the entire oral cavity. Voluntary swallowing (10 mL of pineapple juice or saliva) was monitored for about 30 s in 11 normal subjects at spatial and temporal resolution of 1.3 * 1.3 * 8 mm3 and 40 ms, respectively. Simultaneously, the intraoral atmospheric pressure was recorded at a resolution of 10 ms during the entire course of deglutition. Quantitative measures of bolus transport, larynx elevation and submental muscle changes were obtained from the image series. As a key result, negative intraoral pressure accompanied laryngeal elevation during swallowing in all subjects. A reduction in submental muscle length during swallowing was also observed. No correlations of maximum negative pressure with larynx elevation and submental muscle change were found. In conclusion, intraoral pressure reduction during swallowing is not connected to oral bolus transport, but supports laryngeal elevation by palatal fixation of the tongue. PMID- 27687294 TI - The influence of the menstrual cycle on reactivity to a CO2 challenge among women with and without premenstrual symptoms. AB - Clinically significant premenstrual symptoms (PMS) is conceptualized as a depressive disorder in DSM-5, however, it may share pathophysiological processes with anxiety- and fear-related disorders. Specifically, women with PMS panic at higher rates during biological challenge procedures. It is unclear if this increased interoceptive sensitivity is a general vulnerability or specific to the premenstrual phase. The current study examined the role of menstrual cycle phase on reactivity to a CO2 challenge among women with (n = 11) and without (n = 26) clinically significant PMS (N = 37). During the late follicular phase (days 6 12), women with and without PMS responded similarly to the CO2 challenge, whereas during the premenstrual phase (within 5 days before menses), women with PMS reported significantly more intense panic symptoms in response to the challenge than women without PMS. Vulnerability to panic in women with PMS may be specific to the premenstrual phase. Potential psychological and neurobiological mechanisms underlying this phenomenon are discussed. PMID- 27687295 TI - Decision making about Pap test use among Korean immigrant women: A qualitative study. AB - BACKGROUND: Understanding how individuals make decisions about Pap tests concerning their personal values helps health-care providers offer tailored approaches to guide patients' decision making. Yet research has largely ignored decision making about Pap tests among immigrant women who experience increased risk of cervical cancer. OBJECTIVE: To explore decision making about Pap tests among Korean immigrant women. METHODS: We conducted a qualitative descriptive study using 32 semi-structured, in-depth interviews with Korean immigrant women residing in a north-eastern metropolitan area. Data were audio-recorded, transcribed verbatim and analysed using inductive coding. RESULTS: Although most women with positive decisions made their own decisions, some women deferred to their providers, and others made decisions in collaboration with their providers and significant others. While women making positive decisions tended to consider both barriers to and facilitators of having Pap tests, women making negative decisions predominantly discussed the barriers to having Pap tests, such as modesty and differences between the South Korean and US health-care systems. The women's reflections on their decisions differed regarding their Pap test decisions. CONCLUSIONS: Women's desired roles in the decision-making process and reflection on their decision outcome appeared to vary, although most participants with positive decisions made their own decisions and were satisfied with their decisions. Future research should conduct longitudinal, quantitative studies to test our findings regarding decision-making processes and outcomes about Pap tests. IMPLICATIONS: The findings should be incorporated into cervical cancer screening practices to fulfil the unmet needs of immigrant women in patient provider communication and to facilitate women's decision making about Pap tests. PMID- 27687296 TI - Phytoestrogens and risk of prostate cancer: an updated meta-analysis of epidemiologic studies. AB - This updated meta-analysis was performed to clarify the relationship between phytoestrogens and prostate cancer risk. Twenty one case-control and two cohort studies were finally selected for this meta-analysis, totaling 11,346 cases and 140,177 controls. Analytical results showed that daidzein (OR = 0.85; 95% CI: 0.75-0.96), genistein (OR = 0.87; 95% CI: 0.78-0.98), and glycitein (OR = 0.89; 95% CI: 0.81-0.98) were associated with a reduction of prostate cancer risk, but total isoflavones (OR = 0.93; 95% CI: 0.84-1.04), equol (OR = 0.86; 95% CI: 0.66 1.14), total lignans (OROgna.05; 95% CI: 0.54-2.04), secoisolariciresinol (OR = 1.02; 95% CI: 0.83-1.24), matairesinol (OR = 0.91; 95% CI: 0.75-1.11), enterolactone (OR = 0.94; 95% CI: 0.73-1.20), and coumestrol (OR = 0.89; 95% CI: 0.76-1.06) were not. Sensitivity and publication bias analyses demonstrated that the pooled estimates were stable and reliable. The results support the notion that some phytoestrogens may have a role in decreasing the risk of prostate cancer. Additional large and well-designed cohort studies are needed to confirm these relationships. PMID- 27687297 TI - Recombinant flavin-dependent halogenases are functional in tobacco chloroplasts without co-expression of flavin reductase genes. AB - Halogenation of natural compounds in planta is rare. Herein, a successful engineering of tryptophan 6-halogenation into the plant context by heterologous expression of the Streptomyces toxytricini Stth gene and localization of its enzymatic product in various tobacco cell compartments is described. When co expressed with the flavin reductase rebF from Lechevalieria aerocolonigenes, Stth efficiently produced chlorinated tryptophan in the cytosol. Further, supplementation of KBr yielded the brominated metabolite. More strikingly, targeting of the protein to the chloroplasts enabled effective halogenation of tryptophan even in absence of the partner reductase, providing crucial evidence for sufficient, organelle-specific supply of the FADH2 cofactor to drive halogen integration. Incorporation of an alternative enzyme, the 7-halogenase RebH from L. aerocolonigenes, into the metabolic set-up resulted in the formation of 6,7 dichlorotryptophan. Finally, expression of tryptophan decarboxylase (tdc) in concert with stth led to the generation of 6-chlorotryptamine, a new-to-nature precursor of monoterpenoid indole alkaloids. In sum, the report highlights the tremendous application potential of plants as a unique chassis for the engineering of rare and valuable halogenated natural products, with chloroplasts as the cache of reduction equivalents driving metabolic reactions. PMID- 27687298 TI - Pre-steady state kinetics of DNA binding and abasic site hydrolysis by tyrosyl DNA phosphodiesterase 1. AB - Tyrosyl-DNA phosphodiesterase 1 (Tdp1) processes DNA 3'-end-blocking modifications, possesses DNA and RNA 3'-nucleosidase activity and is also able to hydrolyze an internal apurinic/apyrimidinic (AP) site and its synthetic analogs. The mechanism of Tdp1 interaction with DNA was analyzed using pre-steady state stopped-flow kinetics with tryptophan, 2-aminopurine and Forster resonance energy transfer fluorescence detection. Phosphorothioate or tetramethyl phosphoryl guanidine groups at the 3'-end of DNA have been used to prevent 3'-nucleosidase digestion by Tdp1. DNA binding and catalytic properties of Tdp1 and its mutants H493R (Tdp1 mutant SCAN1) and H263A have been compared. The data indicate that the initial step of Tdp1 interaction with DNA includes binding of Tdp1 to the DNA ends followed by the 3'-nucleosidase reaction. In the case of DNA containing AP site, three steps of fluorescence variation were detected that characterize (i) initial binding the enzyme to the termini of DNA, (ii) the conformational transitions of Tdp1 and (iii) search for and recognition of the AP-site in DNA, which leads to the formation of the catalytically active complex and to the AP site cleavage reaction. Analysis of Tdp1 interaction with single- and double stranded DNA substrates shows that the rates of the 3'-nucleosidase and AP-site cleavage reactions have similar values in the case of single-stranded DNA, whereas in double-stranded DNA, the cleavage of the AP-site proceeds two times faster than 3'-nucleosidase digestion. Therefore, the data show that the AP-site cleavage reaction is an essential function of Tdp1 which may comprise an independent of AP endonuclease 1 AP-site repair pathway.

PMID- 27687304 TI - Anti-PD-1 therapy in patients with advanced melanoma and preexisting autoimmune disorders or major toxicity with ipilimumab. AB - Background: Anti-PD-1 antibodies (anti-PD-1) have clinical activity in a number of malignancies. All clinical trials have excluded patients with significant preexisting autoimmune disorders (ADs) and only one has included patients with immune-related adverse events (irAEs) with ipilimumab. We sought to explore the safety and efficacy of anti-PD-1 in such patients. Patients and methods: Patients with advanced melanoma and preexisting ADs and/or major immune-related adverse events (irAEs) with ipilimumab (requiring systemic immunosuppression) that were treated with anti-PD-1 between 1 July 2012 and 30 September 2015 were retrospectively identified. Results: One hundred and nineteen patients from 13 academic tertiary referral centers were treated with anti-PD-1. In patients with preexisting AD (N = 52), the response rate was 33%. 20 (38%) patients had a flare of AD requiring immunosuppression, including 7/13 with rheumatoid arthritis, 3/3 with polymyalgia rheumatica, 2/2 with Sjogren's syndrome, 2/2 with immune thrombocytopaenic purpura and 3/8 with psoriasis. No patients with gastrointestinal (N = 6) or neurological disorders (N = 5) flared. Only 2 (4%) patients discontinued treatment due to flare, but 15 (29%) developed other irAEs and 4 (8%) discontinued treatment. In patients with prior ipilimumab irAEs requiring immunosuppression (N = 67) the response rate was 40%. Two (3%) patients had a recurrence of the same ipilimumab irAEs, but 23 (34%) developed new irAEs (14, 21% grade 3-4) and 8 (12%) discontinued treatment. There were no treatment related deaths. Conclusions: In melanoma patients with preexisting ADs or major irAEs with ipilimumab, anti-PD-1 induced relatively frequent immune toxicities, but these were often mild, easily managed and did not necessitate discontinuation of therapy, and a significant proportion of patients achieved clinical responses. The results support that anti-PD-1 can be administered safely and can achieve clinical benefit in patients with preexisting ADs or prior major irAEs with ipilimumab. PMID- 27687306 TI - Whole-exome sequencing and immune profiling of early-stage lung adenocarcinoma with fully annotated clinical follow-up. AB - Background: Lung adenocarcinomas (LUADs) lead to the majority of deaths attributable to lung cancer. We performed whole-exome sequencing (WES) and immune profiling analyses of a unique set of clinically annotated early-stage LUADs to better understand the pathogenesis of this disease and identify clinically relevant molecular markers. Methods: We performed WES of 108 paired stage I-III LUADs and normal lung tissues using the Illumina HiSeq 2000 platform. Ten immune markers (PD-L1, PD-1, CD3, CD4, CD8, CD45ro, CD57, CD68, FOXP3 and Granzyme B) were profiled by imaging-based immunohistochemistry (IHC) in a subset of LUADs (n = 92). Associations among mutations, immune markers and clinicopathological variables were analyzed using ANOVA and Fisher's exact test. Cox proportional hazards regression models were used for multivariate analysis of clinical outcome. Results: LUADs in this cohort exhibited an average of 243 coding mutations. We identified 28 genes with significant enrichment for mutation. SETD2 mutated LUADs exhibited relatively poor recurrence- free survival (RFS) and mutations in STK11 and ATM were associated with poor RFS among KRAS-mutant tumors. EGFR, KEAP1 and PIK3CA mutations were predictive of poor response to adjuvant therapy. Immune marker analysis revealed that LUADs in smokers and with relatively high mutation burdens exhibited increased levels of immune markers. Analysis of immunophenotypes revealed that LUADs with STK11 mutations exhibited relatively low levels of infiltrating CD4+/CD8+ T-cells indicative of a muted immune response. Tumoral PD-L1 was significantly elevated in TP53 mutant LUADs whereas PIK3CA mutant LUADs exhibited markedly down-regulated PD-L1 expression. LUADs with TP53 or KEAP1 mutations displayed relatively increased CD57 and Granzyme B levels indicative of augmented natural killer (NK) cell infiltration. Conclusion(s): Our study highlights molecular and immune phenotypes that warrant further analysis for their roles in clinical outcomes and personalized immune based therapy of LUAD. PMID- 27687307 TI - Multicenter randomized phase II study of cisplatin and fluorouracil plus docetaxel (DCF) compared with cisplatin and fluorouracil plus Adriamycin (ACF) as preoperative chemotherapy for resectable esophageal squamous cell carcinoma (OGSG1003). AB - Background: This phase II trial evaluated the efficacy of cisplatin and fluorouracil (CF)-based combination neoadjuvant chemotherapy on the outcome of patients with resectable locally advanced esophageal squamous cell carcinoma (ESCC). We compared the recurrence-free survival (RFS) associated with CF plus Adriamycin (ACF) with that associated with CF plus docetaxel (DCF) to select an alternative regimen in a new phase III trial investigating the optimal neoadjuvant treatment of patients with ESCC. Patients and methods: Patients with resectable advanced ESCC were randomly assigned to either ACF (Adriamycin 35 mg/m2, cisplatin 70 mg/m2 i.v. on day 1, fluorouracil 700 mg/m2 continuous infusion for 7 days) every 4 weeks or DCF (docetaxel 70 mg/m2, cisplatin 70 mg/m2 i.v. on day 1, fluorouracil 700 mg/m2 continuous infusion for 5 days) every 3 weeks. Surgery was scheduled after completion of two cycles of chemotherapy. The primary end point was RFS, analyzed by the intention-to-treat. Results: Between October 2011 and October 2013, 162 patients at 10 institutions were enrolled in the study, all of whom were eligible and randomly assigned to the two groups (81 to the ACF group and 81 to the DCF group). The R0 resection rates for the ACF and DCF groups were equivalent (95.9% versus 96.2%, P = 0.93). The 2-year RFS and overall survival rates for DCF versus ACF were 64.1% versus 42.9% (hazard ratio 0.53, 95% confidence interval 0.33-0.83, P = 0.0057) and 78.6% versus 65.4% (P = 0.08), respectively. Conclusion: Compared with ACF, DCF chemotherapy was associated with prolonged RFS for patients with resectable advanced ESCC. Thus, DCF chemotherapy has potential as a standard neoadjuvant therapy for resectable ESCC.

PMID- 27687308 TI - Impact of early palliative care on caregivers of patients with advanced cancer: cluster randomised trial. AB - Background: Early palliative care improves the quality of life (QoL) and satisfaction with care of patients with advanced cancer, but little is known about its effect on caregivers. Here, we report outcomes of caregiver satisfaction with care and QoL from a trial of early palliative care. Patients and methods: Twenty-four medical oncology clinics were cluster-randomised, stratified by tumour site (lung, gastrointestinal, genitourinary, breast and gynaecological), to early palliative care team referral, or to standard oncology care with palliative care only as needed. Caregivers of patients with advanced cancer (clinical prognosis of 6-24 months, Eastern Cooperative Oncology Group 0 2) in both trial arms completed validated measures assessing satisfaction with care (FAMCARE-19) and QoL [SF-36v2 Health Survey; Caregiver QoL-Cancer (CQoL-C)], at baseline and monthly for 4 months. We used a multilevel linear random intercept mixed-effect model to test whether there was improvement in the intervention group relative to the control group over 3 and 4 months. Results: A total of 182 caregivers completed baseline measures (94 intervention, 88 control); 151 caregivers (77 intervention, 74 control) completed at least one follow-up assessment. Satisfaction with care improved in the palliative intervention group compared with controls over 3 months (P = 0.007) and 4 months (P = 0.02). There was no significant improvement in the intervention group compared with controls for CQoL-C (3 months: P = 0.92, 4 months: P = 0.51), Physical Component Summary of the SF-36v2 Health Survey (3 months: P = 0.83, 4 months: P = 0.20), or Mental Component Summary of the SF-36v2 Health Survey (3 months: P = 0.87, 4 months: P = 0.60). Conclusion: Early palliative care increased satisfaction with care in caregivers of patients with advanced cancer. ClinicalTrials.gov identifier: NCT01248624.

PMID- 27687309 TI - Quantitative proteomic analysis of HER2 expression in the selection of gastric cancer patients for trastuzumab treatment. AB - Background: A wide range of response rates have been reported in HER2-positive gastric cancer (GC) patients treated with trastuzumab. Other HER2-targeted therapies for GC have yet to show efficacy in clinical trials. These findings raise question about the ability of standard HER2 diagnostics to accurately distinguish between GC patients who would and would not benefit from anti-HER2 therapies. Patients and methods: GC patients (n = 237), including a subset from the Trastuzumab in GC (ToGA) trial were divided into three groups based on HER2 status and history of treatment with standard chemotherapy or chemotherapy plus trastuzumab. We applied mass spectrometry-based proteomic analysis to quantify HER2 protein expression in formalin-fixed tumor samples. Using HER2 expression as a continuous variable, we defined a predictive protein level cutoff to identify which patients would benefit from trastuzumab. We compared quantitated protein level with clinical outcome and HER2 status as determined by conventional HER2 diagnostics. Results: Quantitative proteomics detected a 115-fold range of HER2 protein expression among patients diagnosed as HER2 positive by standard methods. A protein level of 1825 amol/ug was predicted to determine benefit from the addition of trastuzumab to chemotherapy. Trastuzumab treated patients with HER2 protein levels above this cutoff had twice the median overall survival (OS) of their counterparts below the cutoff (35.0 versus 17.5 months, P = 0.011). Conversely, trastuzumab-treated patients with HER2 levels below the cutoff had outcomes similar to HER2-positive patients treated with chemotherapy. (Progression-free survival = 7.0 versus 6.5 months: P = 0.504; OS = 17.5 versus 12.6 months: P = 0.520). HER2 levels were not prognostic for response to chemotherapy. Conclusions: Proteomic analysis of HER2 expression demonstrated a quantitative cutoff that improves selection of GC patients for trastuzumab as compared with current diagnostic methods.

AB - Background: Sinonasal carcinomas (SNCs) comprise various rare tumor types that are characterized by marked histologic diversity and largely unknown molecular profiles, yet share an overall poor prognosis owing to an aggressive clinical course and frequent late-stage diagnosis. The lack of effective systemic therapies for locally advanced or metastatic SNC poses a major challenge to therapeutic decision making for individual patients. We here aimed to identify actionable genetic alterations in a patient with metastatic SNC whose tumor, despite all diagnostic efforts, could not be assigned to any known SNC category and was refractory to multimodal therapy. Patients and methods: We used whole exome and transcriptome sequencing to identify a KIT exon 11 mutation (c.1733_1735del, p.D579del) as potentially druggable target in this patient and carried out cancer hotspot panel sequencing to detect secondary resistance conferring mutations in KIT. Furthermore, as a step towards clinical exploitation of the recently described signatures of mutational processes in cancer genomes, we established and applied a novel bioinformatics algorithm that enables supervised analysis of the mutational catalogs of individual tumors. Results: Molecularly guided treatment with imatinib in analogy to the management of gastrointestinal stromal tumor (GIST) resulted in a dramatic and durable response with remission of nearly all tumor manifestations, indicating a dominant driver function of mutant KIT in this tumor. KIT dependency was further validated by a secondary KIT exon 17 mutation (c.2459_2462delATTCinsG, p.D820_S821delinsG) that was detected upon tumor progression after 10 months of imatinib treatment and provided a rationale for salvage therapy with regorafenib, which has activity against KIT exon 11/17 mutant GIST. Conclusions: These observations highlight the potential of unbiased genomic profiling for uncovering the vulnerabilities of individual malignancies, particularly in rare and unclassifiable tumors, and underscore that KIT exon 11 mutations represent tractable therapeutic targets across different histologies.

AB - INTRODUCTION AND OBJECTIVES: Quadratus Lumborum block was recently described and has already shown good results as an analgesic technique in abdominal surgeries, having the potential to significantly reduce opioids consumption and be a valid alternative to epidural catheter. We performed a type II Quadratus Lumborum block for analgesia in a septic patient having a sub-total gastrectomy. CASE REPORT: An 80 year-old, ASA III, male patient, weighting 50kg, with a history of arterial hypertension and hypercholesterolemia, diagnosed with sepsis due to purulent peritonitis was submitted to an open laparotomy. Bilateral ultrasound-guided type II Quadratus Lumborum block was performed before surgery, using 10mL of levobupivacaine 0.25% and 5mL of mepivacaine 1%, per side. Pain relief was achieved 5minutes after injection and the patient referred no pain in the immediate postoperative period. DISCUSSION: Type II Quadratus Lumborum block may be considered a valid alternative for postoperative analgesia in a septic patient undergoing major abdominal surgery with some relative contraindications to epidural catheter placement. It allowed us to achieve excellent pain management avoiding opioids usage. However, more reports are still needed to properly access its usefulness. PMID- 27687316 TI - [Effect of equipotent doses of bupivacaine and ropivacaine in high-fat diet fed neonatal rodent model]. AB - OBJECTIVES: The increase in the prevalence of obesity presents a significant health and economic problem. Obesity has been reported to be a major contributor to variety of chronic diseases. Childhood obesity has been rising over the past decades leading to various complications in health. Millions of infants and children undergo surgery every year on various health grounds. The present investigation was undertaken to evaluate the effect of spinal anesthesia of equipotent doses of ropivacaine and bupivacaine on over-weight neonatal rats. METHODS: The Sprague-Dawley rat pups were overfed on high fat diet to induce obesity. Behavioral assessments for sensory and motor blockade was made by evaluating thermal and mechanical withdrawal latencies at various time intervals following intrathecal injections of bupivacaine (5.0mg.kg-1) and ropivacaine (7.5mg.kg-1) in P14 rats. Spinal tissue was analyzed for apoptosis by determination of activated caspase-3 using monoclonal anti-activated caspase-3 and Fluoro-Jade C staining. Long-term spinal function in P30 rat pups was evaluated. RESULTS: Exposure to intrathecal anesthesia in P14 increased thermal and mechanical latencies and was observed to increase apoptosis as presented by increase in activated caspase-3 and Fluro-Jade C positive cells. Significant alterations in spinal function were observed in high fat diet-fed pups as against non-obese control pups that were on standard diet. Bupivacaine produced more pronounced apoptotic effects on P14 pups; ropivacaine however produced long lasting effects as evidenced in motor function tests at P30. CONCLUSION: Ropivacaine and bupivacaine induced spinal toxicity that was more pronounced in over-fed rat pups as against normal controls.

AB - Anti-N-methyl-d-aspartate receptor encephalitis is a recently described neurological disorder and an increasingly recognized cause of psychosis, movement disorders and autonomic dysfunction. We report 20-year-old Chinese female who presented with generalized tonic-clonic seizures, recent memory loss, visual hallucinations and abnormal behavior. Anti-N-methyl-d-aspartate receptor encephalitis was diagnosed and a computed tomography scan of abdomen reviewed a left adnexal tumor. We describe the first such case report of a patient with anti N-methyl-d-aspartate receptor encephalitis who was given a bilateral transversus abdominis plane block as the sole anesthetic for removal of ovarian tumor. We also discuss the anesthetic issues associated with anti-N-methyl-d-aspartate receptor encephalitis. As discovery of tumor and its removal is the focus of initial treatment in this group of patients, anesthetists will encounter more such cases in the near future.

AB - I report a case of hypotension and bradycardia before spinal anesthesia in a pregnant woman with mild to moderate hypertension treated with nifedipine and methyldopa, scheduled for an elective cesarean delivery. She had the history of neurally-mediated syncopes. Two main factors (increased vagal tone and adverse effects of antihypertensive drugs) could explain the hypotension and bradycardia before spinal anesthesia. Monitoring allowed recognizing the problem and corrected it. Thus, it was avoided a disaster in anesthesia, as hemodynamic changes after spinal anesthesia, they would have joined to previous hypotension and bradycardia, which would have caused even a cardiac arrest. PMID- 27687319 TI - First-line treatment of NSCLC with bevacizumab: real world data from an Italian regional based survey. AB - BACKGROUND: We aimed to explore the use of platinum plus bevacizumab in a real world NSCLC population. PATIENTS AND METHODS: We retrospectively collected data from patients affected by NS-NSCLC treated with platinum plus bevacizumab across Tuscany. RESULTS: We evaluated 62 (median age: 63.5 [30-77] years) pts. All but one presented with adenocarcinoma and the majority had ECOG PS of 0/1. 17.7% presented with central lesion, 11.3% with brain metastasis, 38.7% with hypertension and 4.8% with mild haemoptysis. We observed a median time to progression (TTP) of 6.5 [2-37] and a median overall survival (OS) of 10.5 [2-39] months. Overall response rate (ORR) was 59.6% with a disease control rate (DCR) of 80.6%. Safety profile was acceptable. We observed five cardiovascular events and two major bleedings with no toxic deaths. CONCLUSION: Safety and efficacy real world data are consistent with those from clinical trials even in a less selected population. PMID- 27687320 TI - Study of the optimum haplotype length to build genomic relationship matrices. AB - BACKGROUND: As genomic data becomes more abundant, genomic prediction is more routinely used to estimate breeding values. In genomic prediction, the relationship matrix ([Formula: see text]), which is traditionally used in genetic evaluations is replaced by the genomic relationship matrix ([Formula: see text]). This paper considers alternative ways of building relationship matrices either using single markers or haplotypes of different lengths. We compared the prediction accuracies and log-likelihoods when using these alternative relationship matrices and the traditional [Formula: see text] matrix, for real and simulated data. METHODS: For real data, we built relationship matrices using 50k genotype data for a population of Brahman cattle to analyze three traits: scrotal circumference (SC), age at puberty (AGECL) and weight at first corpus luteum (WTCL). Haplotypes were phased with hsphase and imputed with BEAGLE. The relationship matrices were built using three methods based on haplotypes of different lengths. The log-likelihood was considered to define the optimum haplotype lengths for each trait and each haplotype-based relationship matrix. RESULTS: Based on simulated data, we showed that the inverse of [Formula: see text] matrix and the inverse of the haplotype relationship matrices for methods using one-single nucleotide polymorphism (SNP) phased haplotypes provided coefficients of determination (R2) close to 1, although the estimated genetic variances differed across methods. Using real data and multiple SNPs in the haplotype segments to build the relationship matrices provided better results than the [Formula: see text] matrix based on one-SNP haplotypes. However, the optimal haplotype length to achieve the highest log-likelihood depended on the method used and the trait. The optimal haplotype length (7 to 8 SNPs) was similar for SC and AGECL. One of the haplotype-based methods achieved the largest increase in log-likelihood for SC, i.e. from -1330 when using [Formula: see text] to -1325 when using haplotypes with eight SNPs. CONCLUSIONS: Building the relationship matrix by using haplotypes that comprise multiple SNPs will increase the accuracy of estimated breeding values. However, the optimum haplotype length that shows the correct relationship among individuals for each trait can be derived from the data. PMID- 27687321 TI - Predictors of renal dysfunction after endovascular and open repair of abdominal aortic aneurysms. AB - OBJECTIVE: Renal complications after repair of abdominal aortic aneurysms (AAAs) have been associated with increased morbidity and mortality. However, limited data have assessed risk factors for renal complications in the endovascular era. This study aimed to identify predictors of renal complications after endovascular AAA repair (EVAR) and open repair. METHODS: Patients who underwent EVAR or open repair of a nonruptured infrarenal AAA between 2011 and 2013 were identified in the National Surgical Quality Improvement Project Targeted Vascular module. Patients on hemodialysis preoperatively were excluded. Renal complications were defined as new postoperative dialysis or creatinine increase >2 mg/dL. Patient demographics, comorbidities, glomerular filtration rate (GFR), operative details, and outcomes were compared using univariate analysis between those with and without renal complications. Multivariable logistic regression was used to identify independent predictors of renal complications. RESULTS: We identified 4503 patients who underwent elective repair of an infrarenal AAA (EVAR: 3869, open repair: 634). Renal complication occurred in 1% of patients after EVAR and in 5% of patients after open repair. There were no differences in comorbidities between patients with and without renal complications. A preoperative GFR <60 mL/min/1.73m2 occurred more frequently among patients with renal complications (EVAR: 81% vs 37%, P < .01; open: 60% vs 34%, P < .01). The 30-day mortality was also significantly increased (EVAR: 55% vs 1%, P < .01; open: 30% vs 4%, P < .01). After adjustment, renal complications were strongly associated with 30-day mortality (odds ratio [OR], 38.3; 95% confidence interval [CI], 20.4-71.9). Independent predictors of renal complications included GFR <60 mL/min/1.73m2 (OR, 4.6; 95% CI, 2.4-8.7), open repair (OR, 2.6; 95% CI, 1.3-5.3), transfusion (OR, 6.1; 95% CI, 3.0-12.6), and prolonged operative time (OR, 3.0; 95% CI, 1.6-5.6). CONCLUSIONS: Predictors of renal complications include elevated baseline GFR, open approach, transfusion, and prolonged operative time. Given the dramatic increase in mortality associated with renal complications, care should be taken to use renal protective strategies, achieve meticulous hemostasis to limit transfusions, and to use an endovascular approach when technically feasible. PMID- 27687322 TI - Early infection risk with primary versus staged Hemodialysis Reliable Outflow (HeRO) graft implantation. AB - OBJECTIVE: This study evaluated whether the use of a staged Hemodialysis Reliable Outflow (HeRO; Merit Medical, South Jordan, Utah) implantation strategy incurs increased early infection risk compared with conventional primary HeRO implantation. METHODS: A retrospective review was performed of 192 hemodialysis patients who underwent HeRO graft implantation: 105 patients underwent primary HeRO implantation in the operating room, and 87 underwent a staged implantation where a previously inserted tunneled central venous catheter was used for guidewire access for the venous outflow component. Within the staged implantation group, 32 were performed via an existing tunneled hemodialysis catheter (incidentally staged), and 55 were performed via a tunneled catheter inserted across a central venous occlusion in an interventional radiology suite specifically for HeRO implantation (intentionally staged). Early infection was defined as episodes of bacteremia or HeRO infection requiring resection <=30 days of HeRO implantation. RESULTS: For staged HeRO implantations, the median interval between tunneled catheter insertion and conversion to a HeRO graft was 42 days. The overall HeRO-related infection rate <=30 days of implantation was 8.6% for primary HeRO implantation and 2.3% for staged implantations (P = .12). The rates of early bacteremia and HeRO resection requiring surgical resection were not significantly different between groups (P = .19 and P = .065, respectively), nor were age, gender, laterality, anastomosis to an existing arteriovenous access, human immunodeficiency virus status, diabetes, steroids, chemotherapy, body mass index, or graft location. None of the patient variables, techniques, or graft related variables correlated significantly with the early infection rate. CONCLUSIONS: The staged HeRO implantation strategy did not result in an increased early infection risk compared with conventional primary implantation and is thus a reasonable strategy for HeRO insertion in hemodialysis patients with complex central venous disease. PMID- 27687323 TI - Midterm results from a physician-sponsored investigational device exemption clinical trial evaluating physician-modified endovascular grafts for the treatment of juxtarenal aortic aneurysms. AB - OBJECTIVE: The objective of this study was to report midterm results of an ongoing physician-sponsored investigational device exemption pivotal clinical trial using physician-modified endovascular grafts (PMEGs) for treatment of patients with juxtarenal aortic aneurysms who are deemed unfit for open repair. METHODS: Data from a nonrandomized, prospective, consecutively enrolling investigational device exemption clinical trial were used. Data collection began on April 1, 2011, and data lock occurred on May 31, 2015, with outcomes analysis through December 31, 2015. Primary safety and efficacy end points were used to measure treatment success. The primary safety end point was defined as the proportion of subjects who experienced a major adverse event within 30 days of the procedure. The primary efficacy end point was the proportion of subjects who achieved treatment success. Treatment success required the following at 12 months: technical success, defined as successful delivery and deployment of a PMEG with preservation of those branch vessels intended to be preserved; and freedom from type I and III endoleak, stent graft migration >10 mm, aortic aneurysm sack enlargement >5 mm, and aortic aneurysm rupture or open conversion. RESULTS: During the 50-month study period, 64 patients were enrolled; 60 began the implant procedure and 59 received the PMEG implant. Aneurysm anatomy, operative details, and lengths of stay were recorded and included aneurysm diameter (mean, 65.9 mm; range, 49-104 mm), proximal seal zone length (mean, 40.8 mm; range, 18.9-72.2 mm), graft manufacture time (mean, 55.1 minutes), procedure time (mean, 156.8 minutes), fluoroscopy time (mean, 39.6 minutes), contrast material use (mean, 75.3 mL), estimated blood loss (mean, 213 mL), and length of hospital stay (mean, 4.1 days) with intensive care unit length of stay (mean, 2.2 days). There were 145 fenestrations made for 110 renal arteries and 38 superior mesenteric arteries (SMAs). One patient had an SMA stent placed before the procedure for severe stenosis, and one subject had the SMA stented during the procedure. Renal arteries were stented whenever possible (93%). There were 102 stented renal arteries in 58 patients. There were no open conversions or explantations. Thirty-day mortality was 5.1% (3/59). There were zero type Ia, one type Ib, and two type III endoleaks during follow-up treated with successful reintervention. The overall rate of major adverse events at 30 days was 11.9%. The primary efficacy end points were achieved in 94.1% of patients. CONCLUSIONS: These midterm results are favorable and verify our early report that endovascular repair with PMEG is safe and effective for managing patients with juxtarenal aortic aneurysms. PMEG has exceptional midterm rates of morbidity, mortality, and endoleak and may outperform standard endovascular aneurysm repair with favorable anatomy. In patients who are poor open surgical candidates who present with symptomatic or ruptured juxtarenal aortic aneurysms, PMEG continues to be an extremely appealing option as reliable off-the-shelf solutions are not widely available. Preoperative planning remains the key ingredient for success with use of these techniques. PMID- 27687324 TI - Revascularization of smokers with claudication is not predicted to limit quality of life despite a higher risk of late failure. AB - OBJECTIVE: Tobacco smoking after lower extremity revascularization for claudication has repeatedly been shown to increase the risk of adverse events, such that many vascular specialists consider that refusal to abstain from smoking constitutes a major contraindication to open surgical bypass or endovascular intervention. METHODS: A Markov decision analysis (DA) model was used to compare the options of direct revascularization vs medical therapy only in smokers with claudication. The primary outcome was calculated quality of life (cQoL), determined for each patient at follow-up based on the outcomes of the treatment received. Markov DA software was used to predict the QoL for each treatment option preoperatively based on smoking status. RESULTS: Among patients referred during a recent 64-month period with vasculogenic claudication, 94 were actively smoking compared with 217 who were not. The DA model predicted that if the patients who smoked were to discontinue smoking, the best therapy would be bypass surgery for 77% and endovascular intervention for 17%. However, despite at least doubling the risks with intervention in the patients who continue to smoke, the DA model still predicted that 78% and 9% would fare better with open surgical or endovascular intervention, respectively. Among actively smoking patients, open surgical (3%) or endovascular (4%) therapies were initially performed in few patients, whereas 93% were offered only medical therapy. Among initial nonsmokers, revascularization was performed by open (27%) or endovascular (42%) means. At 3 years, the median (interquartile range [IQR]) cQoL was lower in initial smokers than in nonsmokers (0.73 [IQR, 0.73-0.77] vs 0.82 [IQR, 0.75 0.86]; P < .0001), primarily because of a lack of revascularization for smokers. Among initial smokers who did undergo revascularization initially, because of progression of symptoms, or after smoking cessation, cQoL was similar to initial nonsmokers (0.77 [IQR, 0.73-0.84] vs 0.73 [IQR, 0.73-0.73]; P = .37). Although 26% of initial smokers had stopped by the time of their last follow-up, 10% of initially nonsmoking patients were smoking at follow-up. However, among all patients undergoing intervention, the cQoL of patients smoking at the time of last their follow-up was similar to nonsmokers (0.82 [IQR, 0.82-0.86] vs 0.83 [IQR, 0.73-0.86]; P = .99). CONCLUSIONS: Patients with claudication who smoke may be denied the symptom improvement associated with revascularization, yet recidivism for smoking also occurs among patients who have stopped smoking in order to receive revascularization. The strategy not to directly revascularize patients with claudication who continue to smoke does not appear to maximize patient midterm QoL. PMID- 27687325 TI - Limb-sparing surgery with vascular reconstruction for malignant lower extremity soft tissue sarcoma. AB - BACKGROUND: The standard of care for lower extremity soft tissue sarcoma (STS) is limb-sparing surgery. A small subset of these patients will require concomitant vascular reconstruction to ensure adequate resection and to preserve limb viability and function. The aim of this study was to evaluate outcomes in these patients with respect to wound healing and postoperative functional status. METHODS: Outcomes for a total of 154 patients treated for malignant lower extremity STS during an 8-year period between 2005 and 2013 were entered in a prospective registry. Treatment was by medical management in 3 patients (2%), limb-sparing surgery with vascular reconstruction (LSVR) in 9 patients (6%), and limb-sparing surgery without vascular reconstruction (LS) in 142 patients (92%). The registry and patient records and the intraoperative records were consulted to determine the primary outcomes of patient survival and time for complete wound healing. The functional status of patients was assessed using the Musculoskeletal Tumor Society (MSTS) functional assessment score before surgery and at 6 and 12 months after surgery. RESULTS: Mean follow-up time was 74.7 months for the LSVR group and 53.4 months for the LS group. The mean time to complete wound healing was significantly longer in LSVR vs LS patients (88 days vs 34 days, respectively; P = .002), and overall survival was lower in LSVR patients (P = .01). Seven of the 9 LSVR patients required a total of 12 additional procedures to achieve wound healing, including 9 procedures to drain seromas (incision and drainage) with vacuum-assisted closure in 4 cases. Plastic surgery intervention was required in three patients, including one skin graft, one gracilis pedicle flap, and one vertical rectus abdominis myocutaneous flap. There was no significant difference in the mean MSTS scores preoperatively, at 6 months, and at 1 year after surgery between the two groups (27, 25, and 29 for LSVR vs 28, 31, and 31 for LS, respectively; P = .63, .11, and .67, respectively). CONCLUSIONS: The need for vascular reconstruction during limb-sparing surgery for lower extremity malignant STS is rare in a high-volume sarcoma center. Overall survival was lower in these patients, and the time to complete wound healing is prolonged and requires multiple secondary interventions. However, postoperative functional status as assessed by the MSTS is acceptable and comparable to that of patients not requiring vascular reconstruction.

AB - BACKGROUND: Vascular Ehlers-Danlos syndrome (EDS) is a relatively rare genetic syndrome that occurs owing to disorders in the metabolism of fibrillary collagen. These defects affect the soft connective tissues resulting in abnormalities in the skin, joints, hollow organs, and blood vessels. Patients with these defects frequently present at a young age with spontaneous arterial complications involving the medium-sized arteries. Complications involving the hollow organs, such as spontaneous colonic perforation, are observed as well. Given the fragility of the soft tissue, open and endovascular intervention on patients with vascular EDS is fraught with high complication rates. METHODS: A PubMed search was performed to identify manuscripts published related to vascular EDS. This search included more than 747 articles. These findings were cross-referenced using key terms, including endovascular, embolization, surgery, genetics, pathophysiology, connective tissue disorders, vascular complications, systematic review, type III collagen, and COL3A1. RESULTS: The references in key articles and review articles were evaluated for additional resources not identified in the PubMed search. Care must be taken to balance the risk of intervention vs the risk of continued observation. Life-threatening hemorrhage, however, mandates intervention. CONCLUSIONS: With careful, altered approaches to tissue handling, endovascular approaches may provide a safer option for managing the arterial complications observed in patients with vascular EDS. Additional hope may also be found in the use of pharmacologic agents that reduce the incidence and severity of the arterial complications. PMID- 27687328 TI - Reconstruction for renal artery aneurysms using the tailoring technique. AB - OBJECTIVE: Renal artery (RA) aneurysm (RAA) is a rare and complex disease. Treatment options for a RAA include endovascular surgery and open surgery with ex vivo repair or in situ reconstruction. This study evaluated the long-term outcome after vascular reconstruction of RAAs using the tailoring technique. Tailoring or aneurysmorrhaphy means a partial resection of the aneurysm with direct suture of the remaining arterial wall. METHODS: A single-center retrospective study was conducted between January 1990 and December 2015. The tailoring technique was used to surgically repair 88 RAAs in 80 patients (52 women) with a mean age of 52.9 years. Patients' demographic data, vascular therapy, and renal function during follow-up were retrospectively evaluated. RESULTS: The localization of the RAA was at the right kidney in 58 patients. The mean size of the aneurysm was 21.4 +/- 9.7 mm (range, 8-67 mm). Hypertension was diagnosed in 56 patients, and 23 were asymptomatic. One RAA was ruptured. The overall morbidity rate was 16.3%, including bleeding (n = 4), RA stenosis (n = 3), RA occlusion (n = 4), RA dissection (n = 1), and myocardial infarction (n = 1). One patient died of myocardial infarction for a 30-day mortality rate of 1.3%. The 30-day primary patency rate was 90.0%. The 30-day secondary patency rate was 95.0%. Follow-up data were obtained from 71 patients who underwent tailoring in 78 RAAs. The mean follow-up period was 60.7 months (range 2-229 months). In 76.4% of patients with RAA and hypertension, RAA reconstruction contributed to the cure or improvement of hypertension. The long-term patency after RAA reconstruction was demonstrated in a Kaplan-Meier curve, with cumulative patency rates of 98.7%, 97.4%, 94.8%, and 92.3% after 18, 24, 36, and 48 months, respectively. Estimated survival rates were 98.8%, 97.5%, and 96.3% after 12, 48, and 60 months, with an estimated mean time of 216.5 +/- 7.2 months. CONCLUSIONS: The tailoring technique is a safe and effective procedure with good long-term outcomes. RAA reconstruction contributed to the cure or improvement of renovascular hypertension. PMID- 27687329 TI - Comparison among dimensionality reduction techniques based on Random Projection for cancer classification. AB - Random Projection (RP) technique has been widely applied in many scenarios because it can reduce high-dimensional features into low-dimensional space within short time and meet the need of real-time analysis of massive data. There is an urgent need of dimensionality reduction with fast increase of big genomics data. However, the performance of RP is usually lower. We attempt to improve classification accuracy of RP through combining other reduction dimension methods such as Principle Component Analysis (PCA), Linear Discriminant Analysis (LDA), and Feature Selection (FS). We compared classification accuracy and running time of different combination methods on three microarray datasets and a simulation dataset. Experimental results show a remarkable improvement of 14.77% in classification accuracy of FS followed by RP compared to RP on BC-TCGA dataset. LDA followed by RP also helps RP to yield a more discriminative subspace with an increase of 13.65% on classification accuracy on the same dataset. FS followed by RP outperforms other combination methods in classification accuracy on most of the datasets. PMID- 27687327 TI - Fast-degrading bioresorbable arterial vascular graft with high cellular infiltration inhibits calcification of the graft. AB - OBJECTIVE: Bioresorbable vascular grafts are biologically active grafts that are entirely reconstituted by host-derived cells through an inflammation-mediated degradation process. Calcification is a detrimental condition that can severely affect graft performance. Therefore, prevention of calcification is of great importance to the success of bioresorbable arterial vascular grafts. The objective of this study was to test whether fast-degrading (FD) bioresorbable arterial grafts with high cellular infiltration will inhibit calcification of grafts. METHODS: We created two versions of bioresorbable arterial vascular grafts, slow-degrading (SD) grafts and FD grafts. Both grafts had the same inner layer composed of a 50:50 poly(l-lactic-co-epsilon-caprolactone) copolymer scaffold. However, the outer layer of SD grafts was composed of poly(l-lactic acid) nanofiber, whereas the outer layer of FD grafts was composed of a combination of poly(l-lactic acid) and polyglycolic acid nanofiber. Both grafts were implanted in 8- to 10-week-old female mice (n = 15 in the SD group, n = 10 in the FD group) as infrarenal aortic interposition conduits. Animals were observed for 8 weeks. RESULTS: von Kossa staining showed calcification in 7 of 12 grafts in the SD group but zero in the FD group (P < .01, chi2 test). The cell number in the outer layer of FD grafts was significantly higher than in the SD grafts (SD, 0.87 +/- 0.65 * 103/mm2; FD, 2.65 +/- 1.91 * 103/mm2; P = .02). CONCLUSIONS: The FD bioresorbable arterial vascular graft with high cellular infiltration into the scaffold inhibited calcification of grafts. PMID- 27687330 TI - Delayed Obstruction With Asymptomatic Loss of Renal Function After Dextranomer/Hyaluronic Acid Copolymer (Deflux) Injection for Vesicoureteral Reflux: A Close Look at a Disturbing Outcome. AB - Dextranomer/hyaluronic acid copolymer (Deflux) first received Food and Drug Administration approval in 2001 for endoscopic injection in children with grade II-IV vesicoureteral reflux VUR. As experience has grown, Deflux has been used more liberally with encouraging results. We report 3 cases where Deflux was used in off-label fashion, resulting in delayed ureteral obstruction and loss of renal function (range 18-52 months postoperatively). We now place increased emphasis on the need for long-term follow-up after Deflux in both routine and complex cases, particularly in situations of off-label use. PMID- 27687331 TI - The association between the gut microbiota and the inflammatory bowel disease activity: a systematic review and meta-analysis. AB - BACKGROUND: The pathogenesis of inflammatory bowel diseases (IBD) involves complex interactions between the microbiome and the immune system. We evaluated the association between the gut microbiota and disease activity in IBD patients. METHODS: Systematic review of clinical studies based on a published protocol. Included patients had ulcerative colitis (UC) or Crohn's disease (CD) classified as active or in remission. We selected bacteria assessed in at least three studies identified through electronic and manual searches (November 2015). Bias control was evaluated with the Newcastle Ottawa scale (NOS). Results of random effects meta-analyses were presented as mean differences (MD). RESULTS: Three prospective and seven cross-sectional studies (NOS score 6-8) were included. Five studies included patients with CD (231 patients) and eight included patients with UC (392 patients). Compared to patients in remission, patients with active IBD had lower abundance of Clostridium coccoides (MD = -0.49, 95% CI: -0.79 to 0.19), Clostridium leptum (MD = -0.44, 95% CI: -0.74 to -0.14), Faecalibacterium prausnitzii (MD = -0.81, 95% CI: -1.23 to -0.39) and Bifidobacterium (MD = -0.37, 95% CI: -0.56 to -0.17). Subgroup analyses showed a difference in all four bacteria between patients with UC classified as active or in remission. Patients with active CD had fewer C. leptum, F. prausnitzii and Bifidobacterium, but not C. coccoides. CONCLUSION: This systematic review suggests that dysbiosis may be involved in the activity of IBD and that there may be differences between patients with CD and UC. PMID- 27687332 TI - Complicated function of dopamine in Abeta-related neurotoxicity: Dual interactions with Tyr10 and SNK(26-28) of Abeta. AB - With the capability to inhibit the formation of amyloid beta peptides (Abeta) fibril, dopamine (DA) and other catechol derivatives have been considered for the potential treatment of Alzheimer's disease (AD). Such treatment, however, remains debatable because of the diverse functions of Abeta and DA in AD pathology. Moreover, the complicated oxidation accompanying DA has caused the majority of the previous research to focus on the binding of DA oxides onto Abeta. The molecular mechanism by which Abeta interacts with the reduction state of DA, which is correlative with the brain function, should be urgently explored. By controlling rigorous anaerobic experimental conditions, this work investigated the molecular mechanism of the Abeta/DA interaction, and two binding sites were revealed. For the binding of DA, Tyrosine (Tyr10) was identified as the strong binding site, and serine-asparagine-lysing (SNK(26-28)) segment was the weak binding segment. Furthermore, the Thioflavin T (THT) fluorescence confirmed DA's positive function of inhibiting Abeta aggregation through its weakly binding with SNK(26-28) segment. Meanwhile, 7-OHCCA fluorescence exhibited DA's negative function of enhancing OH generation through inhibiting the Abeta/Cu2+ coordination. The viability tests of the neuroblastoma SH-SY5Y cells displayed that the coexistence of DA, Cu2+, and Abeta induced lower cell viability than free Cu2+, indicating the significant negative effect of excessive DA on AD progression. This research revealed the potential DA-induced damage in AD brain, which is significant for understanding the function of DA in AD neuropathology and for designing a DA-related therapeutic strategy for AD. PMID- 27687333 TI - Organometallic myoglobins: Formation of Fe-carbon bonds and distal pocket effects on aryl ligand conformations. AB - Bioorganometallic Fe-C bonds are biologically relevant species that may result from the metabolism of natural or synthetic hydrazines. The molecular structures of four new sperm whale mutant myoglobin derivatives with Fe-aryl moieties, namely H64A-tolyl-m, H64A-chlorophenyl-p, H64Q-tolyl-m, and H64Q-chlorophenyl-p, have been determined at 1.7-1.9A resolution. The structures reveal conformational preferences for the substituted aryls resulting from attachment of the aryl ligands to Fe at the site of net -NHNH2 release from the precursor hydrazines, and show distal pocket changes that readily accommodate these bulky ligands.

AB - Sodium-glucose cotransporter 2 inhibitors are a novel pharmacological class of oral hypoglycemic agents that lower glucose levels by increasing renal glucose excretion in an insulin-independent manner. However, this seemingly simple mechanism has more complex indirect metabolic effects. The results of randomized clinical trials have shown that these inhibitors effectively lower blood glucose and glycated hemoglobin levels without increasing the risk of hypoglycemia and, at the same time, also reduce bodyweight and systolic blood pressure. In this review, we describe the mechanism of action, efficacy, and safety of currently marketed drugs, as well as other risk factors besides glucose that can potentially be modulated positively. Recent data on empagliflozin showing a significant cardiovascular benefit have compelled us to update knowledge of this new therapeutic class for the treatment of type 2 diabetes. PMID- 27687337 TI - Postanesthesia emergence in patients with post-traumatic stress disorder. AB - STUDY OBJECTIVE: Recovery from anesthesia may be complicated with development of severe panic symptoms and anxiety. Preexisting anxiety disorder has been reported as a risk factor for development of these symptoms. We aimed to examine the frequency of emergence delirium (EDL) among veterans diagnosed with posttraumatic stress disorders (PTSDs). DESIGN: Retrospective cohort. SETTING: Postoperative recovery area. PATIENTS: Perioperative information of 1763 consecutive patients who underwent a surgical procedure requiring general anesthesia were collected. The patients were grouped on the basis of previous diagnosis of PTSD. A total of 317 patients were identified with a positive history of PTSD and were compared to 1446 patients without such a history for the occurrence of EDL in the postanesthesia care unit (PACU) as the primary endpoint. MEASUREMENTS: Duration of stay in PACU in minutes and the frequency of hospital admission were the secondary endpoints. Multivariate binary logistic regression analysis was performed to identify the predictors of EDL among the veteran population. MAIN RESULTS: Emergence delirium was reported in 37 cases (2.1%) after general anesthesia. Fifteen (4.7%) of 317 patients with PTSD and 22 (1.5%) of 1446 patients without history of PTSD demonstrated symptoms related to EDL in the PACU (P=.002). After propensity matching, there were 8 patients with EDL in the PTSD group whereas there were only 2 patients with EDL among controls. Posttraumatic stress disorder was also an independent predictor of EDL in multivariate analysis with an odds ratio of 6.66 and a 95% confidence interval of 2.04 to 21.72 (P=.002). CONCLUSIONS: Posttraumatic stress disorder independently predicted the frequency of EDL even after correcting for preexisting depression and anxiety disorders. A relatively longer duration of PACU stay in PTSD patients may reflect raised awareness of the health care workers about this debilitating mental disorder. PMID- 27687338 TI - Cardiovascular magnetic resonance is successfully feasible in many patients aged 3 to 8years without general anesthesia or sedation. AB - OBJECTIVES: Patients younger than 8 years are usually examined by cardiovascular magnetic resonance (CMR) under general anesthesia (GA) or sedation without intubation. Therefore, we sought to study the feasibility of CMR in patients aged 3 to 8years without GA or sedation. PATIENTS: Data sets of 71 consecutive patients aged 3 to 8years were studied retrospectively. DESIGN: The total cohort was divided into 2 groups: a no-GA or sedation without intubation group (no-GA or sedation) and a GA or sedation without intubation group (GA or sedation). MEASUREMENTS: The patients' age, scan durations for each group, successfully answered clinical question, and number of sequences per study were compared between both groups. MAIN RESULTS: Scan duration in the no-GA or sedation group (n=44) was 35+/- 20minutes, and that in the GA or sedation group (n=27) was 60+/- 31minutes (P<.001). The percentage of successful reports was 95% (42/44) in the no-GA or sedation group and 89% (24 of 27) in the GA or sedation group (P=.29). CONCLUSION: CMR in patients aged 3 to 8years is usually successfully feasible without GA or sedation. PMID- 27687339 TI - Acute stroke after total joint arthroplasty: a population-based trend analysis. AB - STUDY OBJECTIVES: This study aims to determine trends and predictors of acute stroke among total joint arthroplasty (TJA) patients using nationally representative data. DESIGN: Retrospective database review. SETTING: Nationwide Inpatient Sample database. PATIENTS: A total of 1,762,496 TJAs from 2002 to 2011. INTERVENTIONS: Patients underwent primary or revision total hip or total knee arthroplasty. MEASUREMENTS: Development of perioperative acute stroke. MAIN RESULTS: Among 1,762,496 TJAs, 2414 patients (0.14%) developed stroke; 1918 (79.45%) cases were ischemic and the remaining 496 (20.55%) cases were hemorrhagic stroke. The incidence of stroke decreased steadily from 0.17% in 2002 to 0.14% in 2011, which was statistically significant (P<.0001). The in-hospital mortality rate was much higher after stroke at 9% vs 0.15% for general TJA patients. Logistic regression analysis showed that stroke is a strong predictor of in-hospital mortality (odds ratio [OR], 27.73; 95% confidence interval [CI], 23.06-33.05; P<.001). Independent predictors of stroke were presence of pulmonary circulation disorders (including pulmonary embolism; OR, 2.23; 95% CI, 1.73 2.87), advanced diabetes mellitus (OR, 2.10; 95% CI, 1.61-2.73), cardiac arrhythmia (OR, 2.05; 95% CI, 1.83-2.29), peripheral vascular disease (OR, 1.74; 95% CI, 1.42-2.12), valvular heart disease (OR, 1.67; 95% CI, 1.43-1.95), renal disease (OR, 1.66; 95% CI, 1.38-1.99), and revision hip (OR, 1.39; 95% CI, 1.18 1.65). History of stroke or ischemic heart disease was not an independent predictor of stroke. CONCLUSIONS: Despite a decline in the rate of stroke and stroke-related mortality after TJA, stroke still seems to be a major cause of in hospital mortality. The present study outlines some risk factors for stroke after TJA. Recognition of these factors and identification of the at-risk patients may allow for appropriate allocation of resources and ability to minimize this complication after TJA. PMID- 27687340 TI - Anesthetic management of a myotonic dystrophy patient with paraganglionoma. AB - Myotonic dystrophy (DM), though rare, can significantly complicate anesthesia due to muscular and extra-muscular involvement. When this condition is compounded by a pheochromocytoma, anesthetizing such patients becomes extra challenging. We present a case report of a 61-year-old lady with congenital DM, with the whole gamut of associated features, was diagnosed with a noradrenaline secreting paraganglionoma following investigation of refractory hypertension. We anesthetized her for an open resection of the lesion. The conduct of anesthesia and recovery of this patient is described. Our experience suggests that anesthetizing these patients though challenging can be safely managed with relaxant general anesthesia and epidural analgesia with meticulous care pre, intra and post-surgical intervention.

PMID- 27687342 TI - Multisource feedback in professionalism for anesthesia residents. AB - STUDY OBJECTIVE: To assess professionalism in anesthesiology residents, it is important to obtain evaluations from people with whom they interact on daily basis. The purpose of this study was to evaluate the effect of a Multisource feedback (MSF) on resident's professional behavior and to assess the effect of faculty feedback on resident performance. DESIGN: This study was a two-group randomized clinical trial. SETTING: Residents were recruited from Cleveland Clinic Children's Hospital. PATIENTS: Participants included twenty eight residents doing a two-month rotation in Pediatric Anesthesia. INTERVENTIONS: Multisource feedback questionnaires were developed and then validated using face and content validity. Residents were randomly assigned to a feedback group or a control group. Both groups received the MSF evaluation. Only the group assigned to feedback had a 'coaching meeting' every month creating strategies for improvement. MEASUREMENTS: MSF questionnaires were validated using a face validation and expert content validity. The effect of MSF on a professionalism questionnaire was assessed using analysis of covariance and linear mixed effects regression models. MAIN RESULTS: Observed test-retest agreement was greater than 0.90 for all items, with more than half of kappa statistics greater than 0.50. Cronbach's alpha was 0.71.The MSF increased the self-assessment score with an estimated effect of 0.21 (95% CI 0.06, 0.37), P=.015. There was no detected effect on patient family evaluation, with mean difference (CI) in change from baseline of 0.03 (-0.15, 0.21), P=.77, faculty evaluation, 0.21 (-0.02, 0.44), P=.08, or coworker evaluation 0.13 (-0.11, 0.37). CONCLUSIONS: Our new multi source feedback questionnaire to assess professionalism had good reliability and internal consistency. Using our validated questionnaire we assessed the effect of a monthly feedback to improve professionalism in anesthesia residents. While we did see improvement in anesthesiology residents' self-assessment, we did not see a similar effect on patient family, faculty or coworker evaluations. PMID- 27687343 TI - Low-dose butorphanol alleviates remifetanil-induced hyperalgesia in patients undergoing laparoscopic cholecystectomy. AB - OBJECTIVE: To evaluate the effects of low-dose butorphanol on hyperalgesia induced by high-dose remifetanil in patients undergoing laparoscopic cholecystectomy. DESIGN: Randomized double-blind clinical trial. SETTING: Intraoperative. PATIENTS: Seventy-five patients scheduled for laparoscopic cholecystectomy were enrolled. INTERVENTIONS: Randomly allocated into 3 groups, low dose of remifentanil (LR) group and high dose of remifentanil (HR) group received low (0.1MUg kg(-1) min(-1)) or high (0.3MUg kg(-1) min(-1)) doses of remifentanil, respectively, and butorphanol combined with remifentanil (BR) group received remifentanil (0.3MUg kg(-1) min(-1)) and butorphanol (0.2MUg/kg). MEASUREMENTS: The visual analog scale scores and cumulative consumption of fentanyl were recorded. MAIN RESULTS: Visual analog scale scores were significantly higher in the HR group than in the LR and BR groups (P<.001). The dose of intravenously given fentanyl was significantly higher in the HR group than in the LR and BR groups (P<.001). In addition, the HR group showed a significantly higher cumulative consumption of fentanyl during 5 to 8 hours after the operation (P<.001). CONCLUSIONS: A high dose of remifentanil induces postoperative hyperalgesia, which could be prevented by a continuous intravenous administration of a low dose of butorphanol. PMID- 27687344 TI - Dose-ranging effect of systemic diphenhydramine on postoperative quality of recovery after ambulatory laparoscopic surgery: a randomized, placebo-controlled, double-blinded, clinical trial. AB - STUDY OBJECTIVE: Diphenhydramine is an antihistamine with previously demonstrated analgesic and antiemetic properties. However, it is unknown if the beneficial perioperative properties of diphenhydramine can translate to a better quality of postsurgical recovery. The main objective of the current investigation was to investigate dose-ranging effects of diphenhydramine on quality of recovery after surgery. SETTING: Tertiary hospital in the United States. DESIGN: A prospective, randomized, double-blind trial. INTERVENTION: Saline, diphenhydramine 25 >mg, or diphenhydramine 50 mg given intravenously before induction. MEASUREMENTS: The primary outcome was global Quality of Recovery-40 at 24hours. Postoperative pain, nausea, opioid consumption, and discharge time were also evaluated. MAIN RESULTS: Ninety subjects were randomized, and 75 completed the study. The median (interquartile range) Quality of Recovery-40 scores were not different among study groups: 164 (151-189), 169 (159-181), and 172 (157-185) for the saline, 25 mg diphenhydramine, and 50-mg diphenhydramine groups, respectively (P=.74). Postoperative nausea was decreased in the 50-mg group, 3 of 24 (12.5%), compared with the saline group, 12 of 27 (44%), P=.01. There was an inverse linear association between postoperative opioid consumption and quality of recovery (R(2)=0.37, P<.001). CONCLUSIONS: Diphenhydramine does not provide dose-ranging improvements on postoperative quality of recovery after ambulatory laparoscopic gynecologic surgery. Our results support a recent concept that not all postoperative nausea and vomiting symptoms are clinically important. Future studies evaluating postoperative nausea and vomiting should include patient centered outcomes to validate the clinical importance of the examined interventions.

PMID- 27687346 TI - Comparison of volume-controlled ventilation and pressure-controlled ventilation volume guaranteed during laparoscopic surgery in Trendelenburg position. AB - STUDY OBJECTIVE: To analyze the effects of pressure-controlled ventilation-volume guaranteed (PCV-VG) and volume controlled ventilation (VCV) on airway pressures and respiratory and circulatory indicators during laparoscopic surgery in Trendelenburg position. DESIGN: Prospective randomized comparative clinical study. SETTING: Tertiary hospital. PATIENTS: Forty ASA physical status 1 and 2 patients who underwent elective laparoscopic surgery in Trendelenburg position. INTERVENTIONS: Patients were randomly allocated to either VCV group (n=20) or the PCV-VG group (n=20). After induction of anesthesia, for both modes of ventilation, the target tidal volume (VT) was 8mL/kg and the respiratory rate was adjusted to avoid hypercarbia. MEASUREMENTS: The peak and mean inspiratory pressures, dynamic compliance, exhaled VT, oxygenation index and physiological dead space were calculated and recorded at T1, 5minutes after induction of anesthesia in supine position, T2, 5minutes after stabilization of pneumoperitoneum, T3 and T4, 15 and 60minutes after 30 degrees Trendelenburg position with pneumoperitoneum respectively. MAIN RESULTS: PCV-VG group had significantly lower peak inspiratory pressure and greater dynamic compliance than VCV group (P<.001). CONCLUSIONS: In patients who underwent laparoscopic surgery in Trendelenburg position, PCV-VG was superior to VCV in its ability to provide ventilation with lower peak inspiratory pressure and greater dynamic compliance. PMID- 27687348 TI - I have only D-blade: Is it enough? PMID- 27687347 TI - The effect of sugammadex on steroid hormones: A randomized clinical study. AB - STUDY OBJECTIVE: Sugammadex is an alternative drug to traditional decurarization by cholinesterase inhibitors. It has been examined the effect of sugammadex on steroid hormones in this study. DESIGN: Randomized clinical trial. SETTING: The study was conducted in a University Teaching Hospital from January 2013 to May 2014. PATIENTS: Fifty male patients between 18 and 45years of age with an American Society of Anesthesiology (ASA) class I or II undergoing elective lower extremity surgery were included in this study. INTERVENTIONS: Patients were categorized into two groups (neostigmin group, Group N; and sugammadex group, Group S). In addition to standard monitorization, train-of-four (TOF) was also used to monitorize the level of neuromuscular blockade. Standard induction and maintenance of anesthesia were performed. At the termination of surgery, neuromuscular blockade was antagonized using 0.05mg/kg of neostigmine and 0.01mg/kg of atropin when spontaneous recovery of neuromuscular blockade occurred with the reappearance of T2 in Group N and using 4mg/kg sugammadex in Group S. MEASUREMENTS: The primary outcome in this study was to determine serum aldosterone, cortisol, progesterone, and free testosterone levels. Three blood samples were obtained in each patient just before and 15minutes and 4hours after antagonism, MAIN RESULTS: No significant differences were found in demographic characteristics between the groups. While there were no differences in serum progesterone levels, patients in neostigmin group had significantly higher cortisol levels at 15minutes as compared to baseline. Also, patients in sugammadex group had significantly higher serum aldosterone and testosterone levels 15minutes after antagonism as compared to those in the neostigmine group. CONCLUSIONS: Our findings suggest that sugammadex is not associated with adverse effects on steroid hormones progesterone and cortisol, while it may lead to a temporary increase in aldosterone and testosterone.

PMID- 27687350 TI - Transversus abdominis plane block as a component of multimodal analgesia for laparoscopic cholecystectomy. AB - OBJECTIVE: To evaluate and compare intercostal-iliac transversus abdominis plane (TAP) and oblique subcostal TAP (OSTAP) blocks for multimodal analgesia in patients receiving laparoscopic cholecystectomy. DESIGN: A prospective, randomized, double-blinded clinical study. SETTING: Operating room, postoperative recovery area, and ward. PATIENTS: In total, 60 laparoscopic cholecystectomy patients (43 women, 17 men, American Society of Anesthesiologists grades I-II) were enrolled from the general surgery department of our tertiary care center. INTERVENTION: The patients were assigned to 1 of the 3 groups. Group 1 received TAP blocks (n=20), group 2 received OSTAP blocks (n=20), and group 3 patients were used as controls and received patient-controlled analgesia (PCA) only (n=20). After the induction of anesthesia, blocks were performed bilaterally in study groups 1 and 2, using 20mL of lidocaine (5mg/mL). PCA with intravenous tramadol was routinely provided for all patients during the first 24hours. MEASUREMENTS: The intraoperative use of remifentanil, postoperative visual analog scale (VAS) scores, demand for PCA, and total analgesic consumption were recorded. MAIN RESULTS: The patients in the control group had greater analgesic demands and analgesic consumption than did those in groups 1 and 2. However, patients in the OSTAP group had lower VAS scores than did those in groups 1 and 3. RESULTS: The demand for analgesia was greater in the control group than in groups 1 and 2. Moreover, lower VAS scores were recorded in the OSTAP group than in groups 1 and 3 and were positively correlated with total PCA consumption among all patients. However, postoperative VAS scores were negatively correlated with the total intraoperative consumption of remifentanil at 24hours. CONCLUSIONS: TAP and OSTAP blocks improved postoperative analgesia in patients receiving laparoscopic cholecystectomy, which resulted in lower VAS scores and reduction in total analgesic consumption. PMID- 27687351 TI - New technique targeting the C5 nerve root proximal to the traditional interscalene sonoanatomical approach is analgesic for outpatient arthroscopic shoulder surgery. AB - STUDY OBJECTIVE: Regional anesthesia and analgesia for shoulder surgery is most commonly performed via interscalene nerve block. We developed an ultrasound guided technique that specifically targets the C5 nerve root proximal to the traditional interscalene block and assessed its efficacy for shoulder analgesia. DESIGN: Prospective case series. SETTING: Vanderbilt Bone and Joint Surgery Center. PATIENTS: Patients undergoing shoulder arthroscopy at an ambulatory surgery center. INTERVENTIONS: Thirty-five outpatient shoulder arthroscopy patients underwent an analgesic nerve block using a new technique where ultrasound visualization of the C5 nerve root served as the primary target at a level proximal to the traditional interscalene approach. The block was performed with 15mL of 0.5% plain ropivicaine. MEASUREMENTS: Post anesthesia care unit pain scores, opioid consumption, hand strength, and duration of block were recorded. Cadaver dissection after injection with methylene blue confirmed that the primary target under ultrasound visualization was the C5 nerve root. MAIN RESULTS: Pain scores revealed 97% patients had 0/10 pain at arrival to PACU, with 91% having a pain score of 3/10 or less at discharge from PACU. Medical Research Council (MRC) hand strength mean (SD) score was 4.17 (0.92) on a scale of 1-5. The mean (SD) duration of the block was 13.9 (3.5) hours. CONCLUSIONS: A new technique for ultrasound-guided blockade at the level of the C5 nerve root proximal to the level of the traditional interscalene block is efficacious for shoulder post operative pain control.

AB - STUDY OBJECTIVE: The development of outpatient surgery was one of the major goals of public health policy in 2010. The purpose of this observational prospective study was to evaluate the feasibility of laparoscopic sleeve gastrectomy (SG) in an ambulatory setting. DESIGN: Study design was a prospective prospective observational, nonrandomized study, registered (ClinicalTrials.gov identifier: NCT01513005), with institutional review board approval and written informed consent. SETTING: Amiens University Medical Center. PATIENTS: Patients undergoing SG who were preselected by inclusion ambulatory criteria. INTERVENTIONS: All patients operated on for obesity by laparoscopic SG, from May 2011 through July 2013. MEASUREMENTS: We collected outcomes data on 100 patients including incidence of postoperative nausea and vomiting, maximum and average pain scores, and the overall satisfaction rate. MAIN RESULTS: Of the 100 obese patients, 93% were women. The mean age was 36 years (22-55 years). The mean preoperative body mass index was 42.4 kg/m(2). The mean operating time was 60 minutes (range, 30-95 minutes). The overall satisfaction rate was 93% (n = 93). When leaving the postoperative care unit, 94% of patients felt no or mild pain. Eighty-two percent had no postoperative postoperative nausea and vomiting, and 7 patients needed treatment using ondasetron. CONCLUSIONS: Laparoscopic SG in an ambulatory setting is feasible with a dedicated anesthesiological approach and an expert surgical team. Appropriate patient selection is important for ensuring safety and quality of care within the outpatient program. PMID- 27687353 TI - Pectoralis-serratus interfascial plane block vs thoracic paravertebral block for unilateral radical mastectomy with axillary evacuation. AB - STUDY OBJECTIVE: The aim of this study was to evaluate the analgesic efficacy and safety of pectoralis-serratus interfascial plane block in comparison with thoracic paravertebral block for postmastectomy pain. DESIGN: A prospective randomized controlled study. SETTING: Tertiary center, university hospital. PATIENTS: Sixty-four adult women, American Society of Anesthesiologists physical status classes I, II, and III, scheduled for unilateral modified radical mastectomy with axillary evacuation. INTERVENTIONS: Patients were randomized to receive either pectoralis-serratus interfascial plane block, PS group (n=32), or thoracic paravertebral block, PV group (n=32). MEASUREMENTS: Twenty-four-hour morphine consumption and the time to rescue analgesic were recorded. The pain intensity evaluated by visual analog scale (VAS) score at 0, 2, 4, 8, 16, and 24hours postoperatively was also recorded. MAIN RESULTS: The median (interquartile range) postoperative 24-hour morphine consumption was significantly increased in PS group in comparison to PV group (PS vs PV), 20 mg (16-23 mg) vs 12 mg (10-14 mg) (P<.001). The median postoperative time to first analgesic request was significantly shorter in PS group compared to PV group (PS, 6 hours [5-7 hours], vs PV, 11 hours [9-13 hours]) (P<.001). The intensity of pain was low in both groups in VAS 0, 2, and 4hours postoperatively. However, there was significant reduction in VAS in PV group compared to PS group at 8, 16, and 24hours postoperatively. CONCLUSIONS: Pectoralis-serratus interfascial plane block was safe and easy to perform and decreased intensity of postmastectomy pain, but it was inferior to thoracic paravertebral block. PMID- 27687354 TI - The influence of patient position on withdrawal force of lumbar epidural catheters after total knee arthroplasty: A randomized trial. AB - STUDY OBJECTIVE: Elderly patients with degenerative knee disease may have accompanying degenerative spine conditions. There are no studies on lumbar epidural catheter withdrawal forces in these patients. The aim of this study was to investigate withdrawal forces and possible associated risk factors in patients undergoing total knee arthroplasty (TKA). DESIGN: Prospective randomized trial. SETTING: Operating room and ward in a university hospital. PATIENTS: Seventy eight patients aged 65 to 80years who were undergoing TKA and combined spinal epidural anesthesia were enrolled. INTERVENTIONS: Lumbar epidural catheterization was performed in a lateral position before surgery and the patients were randomly allocated to one of 3 positions for removal: flexed lateral (L), prone (P), and sitting (S). On the third postoperative day, the lumbar epidural catheters were removed by a single investigator with the patient in the assigned position. MEASUREMENTS: We measured the peak tension during catheter withdrawal and evaluated the factors affecting peak tension. MAIN RESULTS: The forces required to remove the catheters were considerably greater in the sitting and prone than in the flexed lateral position: group P (3.9N [0.28-10.36]), group S (4.1N [0.04 11.57]), and group L (1.3N [0.07-3.65]) (P<.001). There was a positive correlation between the length of catheter in the epidural space and peak tension (P=.0026, beta coefficient=.223). CONCLUSIONS: For ease of removal of catheters from the lumbar epidural space, the flexed lateral position is recommended for elderly patients undergoing TKA. When placing the epidural catheter, the physician should be careful not to insert a catheter that is excessively long. PMID- 27687355 TI - Entropy vs standard clinical monitoring using total intravenous anesthesia during transvaginal oocyte retrieval in patients for in vitro fertilization. AB - STUDY OBJECTIVE: Day care surgery is an important arena for monitors of anesthetic depth where minimizing drug use is essential for rapid turnover. Underdosage, on the other hand, carries the risks of intraoperative awareness and pain. Transvaginal oocyte retrieval (TVOR), often performed under total intravenous anesthesia using propofol and fentanyl in Indian patients, is a procedure of special interest because, in addition to the above concerns, toxic effects of propofol on oocytes have been described. We have studied the role of entropy monitor, a depth of anesthesia monitor, in optomising drug titration and facilitating distinction between analgesic and hypnotic components of anesthesia. DESIGN: Prospective randomized controlled study. SETTING: Operating theater and postoperative recovery area. PATIENTS: One hundred twenty American Society of Anesthesiologists class I and II female patients coming to the IVF centre for TVOR under total intravenous anesthesia using propofol and fentanyl. They were randomly allocated into 2 groups: Group EM (drugs titrated as per entropy values: state entropy and response entropy) and group CM (drugs titrated as per standard clinical monitoring). INTERVENTION: None. MEASUREMENTS: Total propofol consumption (TP), total fentanyl consumption (TF), on-table recovery time (T1), time to discharge (T2), intraoperative awareness (A). MAIN RESULTS: Patients in group EM demonstrated 6.7% lesser consumption of propofol (P= .01), 10.9% more consumption of fentanyl (P= .007) and 1 minute faster recovery on-table (P= .009) as compared to group CM. In the PACU, only 10% patients of group EM required supplemental analgesia as opposed to 28.3% in CM group (P= .01). Time to discharge was similar in both groups and no intraoperative awareness was noted. CONCLUSION: Entropy monitor is a useful tool allowing distinction between analgesic and hypnotic components of general anesthesia in patients undergoing TVOR and facilitating drug titration accordingly. Its impact on intraoperative awareness needs to be further evaluated. PMID- 27687356 TI - Educational review of Perioperative Medicine for the Junior Clinician. PMID- 27687357 TI - Regional anesthesia practice in China: a survey. AB - STUDY OBJECTIVE: Neuraxial anesthesia has been widely used in China. Recently, Chinese anesthesiologists have applied nerve stimulator and ultrasound guidance for peripheral nerve blocks. Nationwide surveys about regional anesthesia practices in China are lacking. We surveyed Chinese anesthesiologists about regional anesthesia techniques, preference, drug selections, complications, and treatments. DESIGN: A survey was sent to all anesthesiologist members by WeChat. The respondents can choose mobile device or desktop to complete the survey. Each IP address is allowed to complete the survey once. MAIN RESULTS: A total of 6589 members read invitations. A total of 2654 responses were received with fully completed questionnaires, which represented an overall response rate of 40%. Forty-one percent of the respondents reported that more than 50% of surgeries in their hospitals were done under regional anesthesia. Most of the participants used test dose after epidural catheter insertion. The most common drug for test dose was 3-mL 1.5% lidocaine; 2.6% of the participants reported that they had treated a patient with epidural hematoma after neuraxial anesthesia. Most anesthesiologists (68.2%) performed peripheral nerve blocks as blind procedures based on the knowledge of anatomical landmarks. A majority of hospitals (80%) did not stock Intralipid; 61% of the respondents did not receive peripheral nerve block training. CONCLUSIONS: The current survey can serve as a benchmark for future comparisons and evaluation of regional anesthesia practices in China. This survey revealed potential regional anesthesia safety issues in China.

In this case report, we present the perioperative management of a 70-year-old male with a history of HCM who underwent a robotic laparoscopic prostatectomy. Discussion focuses on the utilization of echocardiographic guidance in the care of patients with HCM undergoing noncardiac surgery, as well as the pathophysiology of laparoscopic insufflation and its effects on left ventricular outflow tract obstruction in HCM. PMID- 27687359 TI - A comparison of prophylactic use of meperidine, meperidine plus dexamethasone, and ketamine plus midazolam for preventing of shivering during spinal anesthesia: a randomized, double-blind, placebo-controlled study. AB - STUDY OBJECTIVES: The aim of this study is to compare the efficacy of combination of meperidine and dexamethasone with that of placebo, meperidine alone, and the combination of ketamine and midazolam in preventing shivering during spinal anesthesia. DESIGN: This is a prospective, placebo-controlled study. SETTING: The setting is at an operating room of a university-based teaching hospital. PATIENTS: Two hundred American Society of Anesthesiologists I and II patients undergoing orthopedic and urologic surgery under spinal anesthesia were included. INTERVENTIONS: Subarachnoid anesthesia was performed by using 15mg of 0.5% hyperbaric bupivacaine. Patients were randomly allocated to receive saline (placebo, group C), meperidine 0.4mg/kg (group Me), ketamine 0.25mg/kg plus midazolam 37.5MUg/kg (group KMi), and meperidine 0.2mg/kg plus dexamethasone 0.1mg/kg (group MeD). All drugs were given as an intravenous bolus immediately after intrathecal injection. MEASUREMENTS: During surgery and stay in the recovery room, shivering score, blood pressure, and some other adverse effects were recorded at 5-minute intervals. Axillary and tympanic temperatures were recorded at 15-minute intervals during the perioperative period. MAIN RESULTS: The incidence of shivering after 30minutes of spinal anesthesia in groups C, Me, KMi, and MeD was 64%, 20%, 20%, and 4%, respectively, which was significantly higher in group C compared with other groups (P<.0001). Regarding adverse effects, there was no significant difference between groups (P>=.2). Axillary temperature significantly increased in the 15th-120th-minute interval in groups Me, KMi, and MeD (P<.0001) and in group MeD was higher than that in other groups. Core temperature decreased in the 15th-120th-minute interval in group MeD, lower than that in other groups (P<.0001). CONCLUSIONS: Prophylactic use of meperidine 0.2mg/kg plus dexamethasone 0.1mg/kg was more effective than meperidine 0.4mg/kg as a sole agent or the combination of ketamine 0.25mg/kg and midazolam 37.5MUg/kg in preventing shivering resulting from spinal anesthesia. PMID- 27687360 TI - Comparison of dexamethasone or intravenous fluids or combination of both on postoperative nausea, vomiting and pain in pediatric strabismus surgery. AB - BACKGROUND: Strabismus surgery is perhaps a pediatric surgical procedure that has the strongest evidence of postoperative nausea and vomiting (PONV) risk. This randomized controlled blind study was designed to evaluate the efficacy of combined therapy of dexamethasone and intraoperative superhydration vs their monotherapy on the incidence and severity of PONV and on pain intensity after pediatric strabismus surgery. METHODS: A total of 120 children aged 6 to 12 years undergoing strabismus surgery were randomized to equally 3 groups to receive 0.15 mg/kg dexamethasone (dexamethasone group) or intraoperative superhydration of lactated Ringer's solution in a dose of 30 mL/kg per fasting time (superhydration group), or a combination of dexamethasone and intraoperative fluid in the same strategy (combination therapy group). The incidence and severity of PONV and pain using visual analog scale score, and need for supplemental antiemetic and analgesic therapy and their consumptions were assessed and compared in the 3 studied groups for 24 hours postoperatively. RESULTS: The incidence of PONV and postoperative vomiting was significantly lower (P> .001) in the combination therapy group (5% and 5% respectively) compared with the dexamethasone group (35% and 30%) and superhydration group (32.5% and 35%). There was no significant difference among patients in the superhydration group and dexamethasone group in the cumulative incidences of PONV in the whole 24 hours postoperatively. Postoperative aggregated visual analog scale pain score and total acetaminophen consumption showed a significant reduction (P> .05) in the combination therapy group together with significant prolongation of time to the first analgesic request compared with both the superhydration group and the dexamethasone group. CONCLUSION: Combined therapy of 0.15 mg/kg dexamethasone 1 minute before induction and intraoperative fluid superhydration is an effective and safe way to reduce PONV and pain better than monotherapy of dexamethasone, or intraoperative superhydration separately for pediatric strabismus surgery.

PMID- 27687362 TI - LMA-ProSeal insertion by novice doctors as affected by a 90 degrees bend created by an intubating stylet: a randomized clinical trial. AB - STUDY OBJECTIVE: This study aimed to test the hypothesis that insertion of the supraglottic device LMA-ProSeal (ProSeal) by novice doctors in anesthetized patients can be improved by using an intubating stylet to create a 90 degrees bend and that better sealing pressure is achieved. DESIGN: Randomized clinical trial. SETTING: Operating room. PATIENTS: Seventy adult patients scheduled for elective surgery under general anesthesia using ProSeal with American Society of Anesthesiologists physical status 1 to 3. INTERVENTIONS: ProSeal were inserted with the 90 degrees bend created by the intubating stylet (90D group, 35 patients) or not (ie, conventional insertion; C group, 35 patients). MEASUREMENTS: The number of attempts to successful insertion, sealing pressure, subjective difficulty of insertion by novice doctors, and postoperative pharyngeal pain or hoarseness were compared between groups. MAIN RESULTS: The total number of insertion attempts for the 90D and control groups were 1 (24 and 8, respectively), 2 (8 and 13), 3 (3 and 9), and failure (0 and 5), respectively, showing significant differences between groups (P<.001). Sealing pressure was significantly higher in the 90D group than in the C group (90D group, 23.3+/ 3.7cm H2O; C group, 19.5+/-2.6cm H2O; P<.001), and the subjective difficulty of insertion was significantly lower in the 90D group (90D group, 27.3+/-17.6mm; C group, 55.4+/-22.8mm; P<.001). The incidence of postoperative pharyngeal pain and hoarseness did not differ significantly between groups. CONCLUSIONS: Our results suggest that creating a 90 degrees bend using an intubating stylet facilitates ProSeal insertion by novice doctors, as reflected by higher successful insertion rates, higher sealing pressure, and lower subjective difficulty of insertion in anesthetized patients.

PMID- 27687364 TI - Continuous epidural pumping of saline contributes to prevent and treat postdural puncture headache. AB - STUDY OBJECTIVE: Postdural puncture headache (PDPH) is the most common symptom of accidental dural puncture, a frequent complication of intraspinal anesthesia. We developed a postoperative intervention technique to prevent and treat PDPH in accidental dural puncture patients, including epidural pumping of saline. This retrospective study aimed to retrospectively evaluate this new technique for PDPH prevention and treatment. DESIGN: Retrospective study. SETTING: Beijing Obstetrics and Gynecology Hospital affiliated to the Capital Medical University, between January 2006 and December 2012. PATIENTS: Eighty-seven cases undergoing intraspinal anesthesia were assessed. INTERVENTIONS: Of these patients, 68 cases had successful repuncture and were assigned to group A (epidural filling group, n=68), receiving continuous epidural pumping of 0.9% NS (150mL) at a rate of 6mL/h; the remaining cases were assigned to group B (conservative therapy group, n=19). MEASUREMENTS: Age, height, and body weight were collected, and postoperative headache was assessed using a visual analog scale. MAIN RESULTS: Of 68 patients in group A, 49 (72.1%) developed PDPH, whereas all in group B developed PDPH (P=.009). In addition, all patients showed PDPH within 3days after surgery regardless of treatment group. However, a statistically significant difference was obtained for PDPH duration between groups A and B (P<.001). Multivariate logistic regression analysis showed that frequency of epidural puncture and continuous epidural pumping of saline were significant risk factors for PDPH. CONCLUSIONS: Our data indicated that application of 6mL/h saline effectively contributes to PDPH management, and its clinical application should be broadened. PMID- 27687365 TI - Sonographic evaluation of lumbar interlaminar space opening in a variety of patient body positions for optimal neuraxial anesthesia delivery. AB - OBJECTIVE: To find the position that provided the most comfort, as well as the widest L3-L4 interlaminar space opening. DESIGN: Pilot study. SETTING: Operating room. PATIENTS: Thirty-two healthy volunteers. INTERVENTIONS: L3-L4 interlaminar space was measured on volunteers assuming a baseline position (sitting upright) and 5 study positions: (1) sitting in fetal position, (2) sitting on a table tilted at 30 degrees , (3) sitting while hugging an exercise ball, (4) sitting with midcalves on the table's edge, and (5) lying on one side in fetal position. Interlaminar spaces were measured to determine which position resulted in the largest interlaminar space compared with baseline. The comfort level of each position was rated by subjects using a visual analogue scale from 1 to 10. MAIN RESULTS: The means of the interlaminar openings in all study positions were significantly different from baseline, with the "sitting fetal" having the greatest difference, (1.32mm, P<.001), followed by "hugging a ball" (0.94mm, P<.001) and "lying fetal" (0.92mm, P<.001). Alternatively, when using "sitting fetal" (a more commonly used position) as a comparative baseline, "hugging a ball" and "lying fetal" showed smaller but not significantly different interlaminar openings (Delta=-0.38mm, P value = .221 and Delta=-0.40mm, P value = .164, respectively)."Sitting on a tilted table" and "sitting midcalf" showed significantly smaller interlaminar openings (Delta=-0.52mm, P value = .025 and Delta=-0.72mm, P value < .001, respectively) when compared with the alternative baseline of "sitting fetal." Mean visual analogue scale scores for comfort showed that "hugging a ball" (7.8/10), "lying fetal" (7.5/10), and "sitting fetal" (7.2/10) positions had the highest ratings. CONCLUSIONS: Ultrasonographic measurements carried out on 32 subjects showed that "sitting fetal," "lying fetal," and "hugging a ball" positions provided the widest L3-L4 interlaminar openings. These 3 positions were also found to be more comfortable. PMID- 27687367 TI - Clinical experiences of laser Doppler blood flow sensor for thoracic paravertebral nerve block. PMID- 27687366 TI - Randomized comparison of the feasibility of three anesthetic techniques for day case open inguinal hernia repair. AB - STUDY OBJECTIVE: Comparison of local anesthetic infiltration (LAI), spinal anesthesia (SPIN) and total intravenous anesthesia (TIVA) for open inguinal herniorrhaphy. We hypothesized that patients receiving LAI could be discharged faster than SPIN and TIVA patients. DESIGN: Randomized, prospective trial. SETTING: University hospital day-surgery center. PATIENTS: 156 adult male patients (ASA 1-3) undergoing day-case open inguinal herniorrhaphy. INTERVENTIONS: Patients were randomized to either LAI (lidocaine+ropivacaine), SPIN (bupivacaine+fentanyl) or TIVA (propofol+remifentanil). Perioperative Ringer infusion was 1.5mL/h. Urinary bladder was scanned before and after surgery. Interviews were performed on postoperative days 1, 7 and 90. MEASUREMENTS: Duration of surgery, duration of the patients' stay in the operating room and time until their readiness for discharge home. Patient satisfaction and adverse effects were registered. MAIN RESULTS: Surgery lasted longer in LAI group (median 40min) than in SPIN group (35min) (P=.003) and TIVA group (33min) (P<.001). Although surgery was shortest in TIVA group, TIVA patients stayed longer in the operating room than LAI patients (P=.001). Time until readiness for discharge was shorter in LAI group (93min) than in TIVA (147min) and SPIN (190min) groups (P<.001). Supplementary lidocaine infiltration was given to 32 LAI patients, and IV fentanyl to 29 LAI and 4 SPIN patients. Ephedrine was required in 34 TIVA, 5 LAI and 5 SPIN patients. One SPIN and three LAI patients had to be given TIVA and another SPIN patient LAI to complete the operations. Urinary retention was absent. Discomfort in the scar (26%) three months postoperatively was not anesthesia-related. CONCLUSIONS: Logistically, LAI was superior because of the fastest recovery postoperatively. The anesthetic techniques were adequate for surgery in all but a few LAI and SPIN patients. Lack of urinary retention was probably related to the small IV infusion volumes.

PMID- 27687369 TI - Magnesium sulfate or diltiazem as adjuvants to total intravenous anesthesia to reduce blood loss in functional endoscopic sinus surgery. AB - STUDY OBJECTIVE: This study was designed to know whether addition of magnesium sulfate (MgSO4) or diltiazem to total intravenous anesthesia (TIVA) (propofol) aided reduction in blood loss during functional endoscopic sinus surgery (FESS). The secondary outcomes measured were surgeon's assessment of the surgical field and hemodynamics. DESIGN: Randomized, double-blinded, placebo-controlled trial. SETTING: Operating room. PATIENTS: Forty-five American Society of Anesthesiologists I and II adult patients (18-60years) undergoing FESS. INTERVENTIONS: All groups received propofol-fentanyl TIVA. Patients were randomly allocated to 1 of the 3 groups (MgSO4 group, n=15; diltiazem group, n=15; saline group, n=15). MEASUREMENTS: Intraoperative bleeding was quantified, and quality of surgical field was graded. Hemodynamic parameters were recorded. MAIN RESULTS: Addition of both MgSO4 and diltiazem significantly reduced blood loss (240 and 350mL) in comparison to control group (415mL) (P=.003). The surgical field was significantly better in the MgSO4 group compared with the diltiazem (P=.028) and saline groups (P=.0001). CONCLUSION: It was concluded that the addition of both MgSO4 and diltiazem to TIVA propofol results in significant reduction in blood loss and significant improvement in the quality of surgical field during FESS without causing any adverse effects on the hemodynamics or on the recovery from anesthesia. The surgical field in the MgSO4 group was significantly better than that in the diltiazem group (P=.04). PMID- 27687370 TI - Rocuronium is associated with an increased risk of reintubation in patients with soft tissue infections. AB - STUDY OBJECTIVE: To determine risk factors associated with reintubations in adult patients with soft tissue infections. DESIGN: A retrospective case-control design. SETTING: Operating room and postoperative recovery area. PATIENTS: There were 39 patients who presented for surgical intervention of their soft tissue infection and 222 controls having general surgery who were matched for age, sex, and body mass index. All patients were older than the age of 18 years and mostly American Society of Anesthesiologists physical status of III to IV and presented to our level 1 trauma center. INTERVENTIONS: Reintubation within 2 hours after planned extubation. MEASUREMENTS: The following data were collected: reintubation rates, train of four ratio, reversal agents, age, sex, creatinine, smoking history, transfusion requirements, Sequential Organ Failure Assessment score, hemoglobin, and lactate. MAIN RESULTS: The use of rocuronium was independently associated with increased odds of reintubation. Patients with a higher train of four ratio were more likely to be reintubated and less likely to be reversed as compared to those with a lower train of four ratio. CONCLUSIONS: Soft tissue patients who have received rocuronium are at increased risk for reintubation, particularly those with renal failure. In addition, this article supports the use of neuromuscular blockade reversals, even in patients with a strong train of four ratio.

PMID- 27687372 TI - Transnasal sphenopalatine ganglion block for the treatment of postdural puncture headache in obstetric patients. AB - STUDY OBJECTIVE: To demonstrate a possible alternative treatment for postdural puncture headache (PDPH). DESIGN: Postdural puncture headache is a common complication associated with neuraxial anesthesia and unintentional dural puncture. Epidural blood patch (EBP) is the standard therapy for PDPH but has risks including pain, dural puncture, and infection. Transnasal sphenopalatine ganglion block (SPGB) has been successfully used to treat migraine, cluster headache, and trigeminal neuralgia. This is a small case series in which SPGB was used to treat PDPH in 3 obstetric patients. SETTING: Labor and delivery suite. PATIENTS: Three postpartum patients with PDPH were studied. One patient was American Society of Anesthesiologists physical status 1, and the other 2 were American Society of Anesthesiologists physical status 2. INTERVENTIONS: Transnasal SPGB using cotton-tipped applicators and 2% viscous lidocaine was performed on all 3 patients. MEASUREMENTS: Height, weight, and vital signs were measured on all patients. In addition, the numeric rating scale (0-10) was used to quantify the pain level while in the sitting position preprocedure, immediately postprocedure, 24 hours postprocedure, and 48 hours postprocedure. MAIN RESULTS: All 3 patients had significant pain relief following the SPGB without the need for EBP. CONCLUSIONS: When comparing the risks of a transnasal SPGB, which include bleeding and temporary discomfort, against those of an EBP, which are documented as dural puncture, neurologic complications, bleeding, and infection, it seems reasonable to offer the SPGB before EBP. PMID- 27687373 TI - Effect of depth of neuromuscular blockade on the abdominal space during pneumoperitoneum establishment in laparoscopic surgery. AB - STUDY OBJECTIVE: To evaluate the effect of neuromuscular blockade (NMB) upon the abdominal space during pneumoperitoneum establishment in laparoscopic surgery, comparing moderate NMB and deep NMB. DESIGN: Prospective, randomized, crossover clinical trial. SETTING: Operating room. PATIENTS: Seventy-six American Society of Anesthesiologists 1 to 2 patients scheduled for elective laparoscopic surgery. INTERVENTIONS: Two independent evaluations were performed at the establishment of pneumoperitoneum for a preset intraabdominal pressures (IAPs) of 8 and 12 mm Hg, both during moderate NMB (train-of-four count, 1-3) and deep NMB (posttetanic count, <5). Rocuronium was used to induce NMB, and sugammadex was used for reversal. MEASUREMENTS: We evaluated (i) the volume of CO2 introduced in 41 patients and (ii) the skin-sacral promontory distance in 35 patients, at pneumoperitoneum establishment. RESULTS: Compared to moderate NMB, deep NMB increased, in a significant manner, both the intraabdominal volume of CO2 insufflated (mean [SD], 2.24 [1.10] vs 2.81 [1.13] L at 8 mm Hg IAP, P<.001, and 3.52 [1.31] vs 4.09 [1.31] L at 12 mm Hg IAP, P<.001) and the skin-sacral promontory distance (11.78 [1.52] vs 12.16 [1.51] cm at 8 mm Hg IAP, P=.002, and 13.34 [1.87] vs 13.80 [1.81] cm at 12 mm Hg IAP, P<.001). Increase in intraabdominal volume after inducing deep NMB was observed in 88% and 81.7% of patients at 8 and 12 mm Hg pneumoperitoneum, with a volume increase of mean of 36.8% (95% confidence interval [CI], 22.8-50.8) and 25% (95% CI, 13.7-36.4), respectively (P=.003). Increase in distance was observed in 61% and 82% of patients at 8 and 12 mm Hg pneumoperitoneum, with a mean distance increase of 3.3% (95% CI, 1.3-5.4) and 3.6% (95% CI, 1.9-5.2), respectively (P=.840). CONCLUSIONS: Deep NMB, in comparison to moderate NMB, increased in a significant manner the abdominal space at pneumoperitoneum establishment. However, the effective increase in the abdominal cavity dimensions could be low, the increase showed a great interindividual variability, and it was not observed in every patient. Clinical significance of this increase on surgical conditions is yet to be demonstrated.

PMID- 27687377 TI - A randomized trial comparing prophylactic phenylephrine and ephedrine infusion during spinal anesthesia for emergency cesarean delivery in cases of acute fetal compromise. AB - BACKGROUND: Previous evidence showed that use of phenylephrine was associated with higher umbilical artery pH (UA pH) than ephedrine after elective cesarean delivery (CD). However, the best choice of vasopressor and its effect on funic gases in cases of acute fetal compromise require additional studies. METHODS: Ninety parturients showing acute fetal compromise during intrapartum period and taken up for CD (category II) under spinal anesthesia were randomized to receive prophylactic infusion of ephedrine 2.5mg/min or phenylephrine 30MUg/min. Systolic blood pressure was targeted between 90% and 110% of baseline. Incidence of fetal acidosis (UA pH <7.2 and/or base deficit >12mmol/L) was recorded. Other parameters of cord gases, Apgar score, need for immediate resuscitation, maternal hemodynamics, and adverse events were also compared. RESULTS: Number of neonates showing acidosis with ephedrine or phenylephrine was comparable (P=.22). Of these, newborns with base deficit >12mmol had low 1-minute Apgar scores (n=15/23). The ephedrine group had higher oxygen content in UA (P=.03). There was no adverse neonatal outcome during the period of observation. Incidence of maternal nausea and vomiting was higher with ephedrine than with phenylephrine (22.2% vs 4.4%; P=.02). Maternal bradycardia was observed with phenylephrine (P=.02). CONCLUSION: Our data report similar fetal acidosis with either phenylephrine or ephedrine administered during spinal anesthesia for treating maternal hypotension in cases of emergency CD. PMID- 27687378 TI - Comparing the efficacy and safety between propofol and dexmedetomidine for sedation in claustrophobic adults undergoing magnetic resonance imaging (PADAM trial). AB - STUDY OBJECTIVE: To determine the efficacy of sedation with dexmedetomidine compared to propofol for claustrophobic adults undergoing magnetic resonance imaging (MRI) in our institution. DESIGN: Randomized, prospective, double-blinded study. SETTING: University-based tertiary referral center. PATIENTS: Thirty claustrophobic adults with American Society of Anesthesiologists physical status I and II who were planned for MRI. INTERVENTIONS: Patients were randomly assigned to target-controlled infusion propofol or dexmedetomidine loading followed by maintenance dose for procedural sedation. MEASUREMENTS AND MAIN RESULTS: The primary end point was adequate reduction in patient anxiety levels to allow successful completion of the MRI sequence. Both methods of sedation adequately reduced anxiety levels in visual analog scale scores and Spielberger Strait Test Anxiety Inventory (P<.001). Dexmedetomidine required a longer time to achieve anxiolysis, 7.36minutes (SD, 2.59), and required increasing maintenance dose to induce sleep compared to 10.71minutes (SD, 4.63) for propofol. In terms of image quality, 2 patients (16.67%) in the dexmedetomidine group were satisfactory, whereas all with propofol were graded as good to excellent. Adverse effects were seen in patients sedated with dexmedetomidine with number needed to harm 8 for hypotension and 15 for bradycardia compared to none recorded in the propofol arm. There was no significant difference in patient satisfaction scores or home readiness after the MRI. CONCLUSIONS: Both dexmedetomidine and propofol can effectively reduce anxiety levels of claustrophobic adults undergoing MRI, but dexmedetomidine takes longer to achieve adequate anxiolysis and sleep and may have an effect on image quality. Hypotension and bradycardia are common adverse effects observed with dexmedetomidine. PMID- 27687379 TI - Comparison of the clinical performances of Air-Qsp and i-Gel for airway management under general anesthesia with a muscle relaxant. AB - STUDY OBJECTIVES: Recently, i-Gel intubating laryngeal airway (ILA) has been frequently used because of the ease for airway insertion by residents and young anesthesiologists. However, it sometimes fails to fit or ventilate sufficiently in Japanese patients. Use of Air-Qsp, which is a new non-inflatable cuffed ILA, in a clinical setting has become possible. The purpose of this study was to compare the clinical performance of Air-Qsp with that of i-Gel for airway management in Japanese adult patients. DESIGN: A randomized, single-blinded, prospective study was conducted after approval from the institutional review board. SETTING: Operating rooms at hospitals. PATIENTS: Thirty-seven adult patients aged 20 to 69 years, with ASA physical status I or II, and scheduled for elective surgery under general anesthesia in the supine position. INTERVENTIONS: Patients were randomly assigned to insertion with Air-Qsp (Group A: n=20) or i Gel (Group I: n=17). MEASUREMENTS: The number of insertions, duration of insertion, changes in systolic blood pressure and heart rate during insertion, delivered tidal volume for setting volume control ventilation, distribution of the tips of the bronchofiberscopes (BFs) on a clock face, and the number of postoperative complications was evaluated. MAIN RESULTS: Two patients in Group A and one patient in Group I were excluded because insertion of the device failed. There were no significant differences in measured parameters between the 2 groups. The distribution of the tips of the bronchofiberscopes tended to be around the center of the glottis in Group A, whereas they were more toward the 6 o'clock position in Group I. CONCLUSIONS: Air-Qsp is as useful as i-Gel in Japanese patients and the distributions of the tips of BFs through ILAs are different for Air-Qsp and i-Gel. PMID- 27687380 TI - Dose of intraoperative remifentanil administration is independently associated with increase in the risk of postoperative nausea and vomiting in elective mastectomy under general anesthesia. AB - BACKGROUND: Postoperative nausea and vomiting (PONV) is one of the common complications in patients who have undergone surgery with general anesthesia. The association of intraoperative use of remifentanil with PONV has remained controversial. The aim of the current study was to determine the association of dose of intraoperative remifentanil administration with incidence of PONV. METHODS: The present study was a single-center retrospective observational study and included 423 female patients with American Society of Anesthesiologists physical status I or II who underwent elective mastectomy under general anesthesia between October 2011 and October 2012. The incidence of PONV within 3 days after the operation was prospectively assessed. The time-weighted average of remifentanil during the operation (twRem) was calculated. We used a multivariate regression model to assess the independent association of the twRem with the incidence of PONV. RESULTS: Among 423 patients, 129 patients (30.5%) had PONV during the study period. Remifentanil was administrated in 355 patients (83.9%). In the multivariate logistic regression model using categories of twRem, we found that increased twRem was independently associated with increase in the risk of PONV (P=.01). There was an independent association between twRem greater than 0.2 MUg/kg per minute and increase in the risk of PONV. CONCLUSION: This retrospective observational study revealed a dose-dependent association between dose of intraoperative remifentanil administration and increase in the risk of PONV. Time-weighted average of remifentanil greater than 0.2 MUg/kg per minute was independently associated with risk of PONV. PMID- 27687381 TI - Perioperative factors associated with Hospital Consumer Assessment of Healthcare Providers and Systems responses of total hip arthroplasty patients. AB - OBJECTIVE: To determine perioperative treatments and events associated with Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) responses among patients who undergo total hip arthroplasties (THAs) and total knee arthroplasties (TKAs). DESIGN: Retrospective analysis. SETTING: Single tertiary care, academic, urban, level 1 trauma center. PARTICIPANTS: Final cohort represents 301 consecutive surgical inpatients meeting criteria for evaluation by HCAHPS survey. EXPOSURES: Responses to 4 HCAHPS questions were analyzed against perioperative treatments and events. MEASURES: Positive and negative responses to HCAHPS questions. RESULTS: THA patients responding affirmatively to both pain specific and general satisfaction were associated with preoperative use of chronic nonsteroidal anti-inflammatory drugs. In addition, THA patients responding affirmatively "how often was your pain well controlled" were also associated decreased postanesthesia care unit (PACU) opioid requirement. TKA patients responding affirmatively to "what number would you use to rate this hospital" were associated with shorter PACU stays and lower final pain scores. TKA patients responding affirmatively to "would you recommend this hospital to your family" were associated with shorter lengths of stay in the hospital and in the PACU. TKA patients responding affirmatively to "How often did the hospital staff do everything to help with your pain" were not associated with any measured perioperative event. TKA patients responding affirmatively to "how often was your pain well controlled" were associated with older age, decreased use of preoperative chronic benzodiazepines, and increased use of preoperative midazolam. CONCLUSIONS: These data suggest that chronic use of nonsteroidal anti inflammatory drugs is associated with improved overall satisfaction and satisfaction with pain in THA patients. Furthermore, increased PACU opioid use was negatively associated satisfaction with pain management. Age, lengths of stay preadmission medications, anxiolytic medications, and PACU pain scores are associated with patient satisfaction with regards to both pain management and overall satisfaction in TKA patients. PMID- 27687382 TI - Iterative epidural blood patch for recurrent spontaneous intracranial hypotension during pregnancy. AB - A 30-year-old woman at 28 weeks presented with sudden onset of intense headache, epigastric pain, hot flushes, nausea, vomiting, and stiff neck. Cerebral magnetic resonance imaging showed pathognonomic signs of spontaneous intracranial hypotension (SIH). Epidural blood patch was performed 2 times during pregnancy for symptoms relief in spite of medical treatments. No other recurrence was noted until the spontaneous delivery. SIH is a rare entity during pregnancy which may be diagnosed using magnetic resonance imaging. Iterative Epidural blood patch should be proposed to patients with SIH during pregnancy because it allowed faster symptoms improvement and patient relief with complete recovery than medical treatment only. PMID- 27687383 TI - Real-time measurement of blood pressure with Nexfin in a patient with thalidomide related phocomelia. AB - We report the novel application of photoplethysmographic technology with the Nexfin HD monitor for real-time measurement of blood pressure (BP) in a patient with tetraamelia. The patient was a 58-year-old man with tetraamelia secondary to thalidomide exposure in utero, who presented for surgical excision of a maxillary schwannoma. Because difficulty of cuff use on rudimentary limbs and failure to gain invasive arterial access due to abnormalities of limb vasculature, this population is known to pose some unique challenges for BP measurement. Nexfin may offer an alternative noninvasive method to detect BP in patients with phocomelia during the perioperative period. PMID- 27687384 TI - Effect of thoracic epidural analgesia on recovery of bowel function after major upper abdominal surgery. AB - STUDY OBJECTIVE: We investigated whether thoracic epidural analgesia (TEA) shortens the first gas-out time compared to intravenous patient-controlled analgesia (iv-PCA) and promotes earlier discharge after major upper abdominal surgery. DESIGN: Prospective observational study. SETTING: A tertiary care university hospital. PATIENTS: Fifty-six patients undergoing major upper abdominal surgery. INTERVENTIONS: TEA (n=28) was performed using a paramedian approach at T6-7 or T7-8. Hydromorphone (8 MUg/mL) was added to 0.15% ropivacaine (bolus/lockout time/basal: 3 mL/15 minutes/5 mL). The iv-PCA regimen (n=28) included 20 MUg/mL fentanyl (bolus/lockout time/basal: 0.5 mL/15 minutes/0.5 mL). The 2 analgesic methods were maintained for 3 days. MEASUREMENT: The primary end point was first gas-out time, and the secondary end points were hospital discharge, pain scores, and first voiding time. MAIN RESULTS: No differences in first gas-out time (TEA, 4.1+/-1.2 days; iv-PCA, 3.4+/-1.9 days; P=.15) or hospital stay (TEA, 9.8+/-2.2 days; iv-PCA, 11.4+/-5.2 days; P=.19) were observed between the 2 groups. A visual analog pain scale scores during rest and coughing were lower in the TEA than those for iv-PCA even with 40% to 46% less rescue analgesic. However, TEA delayed first voiding time (3.6+/-0.9 vs 2.8+/-1.6 days; P=.02) and required more frequent bladder catheterization (46% vs 11%; P=.008) than those of iv-PCA. CONCLUSION: TEA with a regimen of hydromorphone (8 MUg/mL) added to 0.15% ropivacaine did not provide earlier gas-out compared to that of iv PCA in patients who underwent major upper abdominal surgery.

AB - STUDY OBJECTIVE AND DESIGN: To evaluate the hypothesis that assigning grades to magnetic resonance imaging (MRI) findings of suspected placenta accreta will correlate with hemorrhagic outcomes. We chose a single-center, retrospective, observational design. SETTING, PATIENTS, AND MEASUREMENTS: Nulliparous or multiparous women who had antenatal placental MRI performed at a tertiary level academic hospital were included. Cases with antenatal placental MRI were included and compared with cases without MRI performed. Two radiologists assigned a probability score for accreta to each study. Estimated blood loss and transfusion requirements were compared among groups by the Kruskal-Wallis H test. RESULTS: Thirty-five cases had placental MRI performed. MRI performance was associated with higher blood loss compared with the non-MRI group (2600 [1400-4500]mL vs 900[600-1500]mL, P<.001). There was no difference in estimated blood loss (P=.31) or transfusion (P=.57) among the MRI probability groups. CONCLUSIONS: In cases of suspected placenta accreta, probability scores for antenatal placental MRI may not be associated with increasing degrees of hemorrhage. Continued research is warranted to determine the effectiveness of assigning probability scores for antenatal accreta imaging studies, combined with clinical indices of suspicion, in assisting with antenatal multidisciplinary team planning for operative management of this morbid condition. PMID- 27687390 TI - Cardiopulmonary exercise testing in a patient with a permanent tracheostomy. AB - The benefits of cardiopulmonary exercise testing have been well established. Certain patient groups present challenges for conducting such a test. We were presented with a patient with a permanent tracheostomy at the preoperative assessment clinic. We describe our technique in overcoming the problem of connecting him to the testing machine, as this is normally done with the aid of a tight-fitting face mask. We used a cuffed tracheostomy tube together with some widely available tubing from theaters to connect the patient to the gas analyzer. The test was only stopped because of excessive secretions from the patient, and we had already established enough data to tell us that the patient was fit enough to proceed to surgery. As more patients present with tracheostomies, we feel that this case would be a useful reference in managing and assessing such patients. PMID- 27687391 TI - Comparing 3 ventilation modalities by measuring several respiratory parameters using the ProSeal laryngeal mask airway in children. AB - STUDY OBJECTIVE: To determine quantitative differences in several routinely measured ventilation parameters using a standardized anesthetic technique and 3 different ventilation modalities in pediatric patients with a ProSeal laryngeal mask airway (PLMA). DESIGN: Randomized prospective study. SETTING: Pediatric hospital of a tertiary care academic medical center. PATIENTS: Thirty-three, American Society of Anesthesiologists classification 1-2, pediatric patients (12 months to 5 years). INTERVENTIONS: Three different ventilation strategies: spontaneous ventilation (SV), pressure support ventilation (PSV), and pressure controlled ventilation (PCV) were randomly applied to patients who underwent a standardized mask induction with sevoflurane/oxygen and propofol 3 mg/kg and morphine 0.05 mg/kg administered intravenously followed by PLMA insertion. Patients were maintained on sevoflurane and N2O. MEASUREMENTS: We measured the differences in end-tidal CO2 (Etco2), tidal volume, and respiratory rate over time between SV, PSV, and PCV. These data were recorded at 5-minute intervals. MAIN RESULTS: Etco2 (mm Hg) was significantly higher in the SV vs PSV (P=.016) and vs PCV (P<.001). Tidal volume (mL/kg) was significantly lower in SV vs PSV (P<.001) and vs PCV (P<.001). Respiratory rate (breaths/min) was significantly higher in SV vs PSV (P<.001) and vs PCV (P=.005). CONCLUSIONS: All 3 modes of ventilation using a PLMA were safely used. Our SV group was noted to have a significantly higher Etco2 when compared with PSV and PCV with a mean Etco2 over time in excess of 55 mm Hg. PSV and PCV were found to be more appropriate ventilation strategies to more optimally control Etco2 over time in these patients. PMID- 27687392 TI - Inappropriately low bispectral index of the elderly during emergence from sevoflurane anesthesia. PMID- 27687393 TI - Unexpectedly high incidence of hypothermia before induction of anesthesia in elective surgical patients. AB - STUDY OBJECTIVE: Perioperative hypothermia is a frequently observed phenomenon of general anesthesia and is associated with adverse patient outcome. Recently, a significant influence of core temperature before induction of anesthesia has been reported. However, there are still little existing data on core temperature before induction of anesthesia and no data regarding potential risk factors for developing preoperative hypothermia. The purpose of this investigation was to estimate the incidence of hypothermia before anesthesia and to determine if certain factors predict its incidence. DESIGN/SETTING/PATIENTS: Data from 7 prospective studies investigating core temperature previously initiated at our department were analyzed. Patients undergoing a variety of elective surgical procedures were included. INTERVENTIONS/MEASUREMENTS: Core temperature was measured before induction of anesthesia with an oral (314 patients), infrared tympanic (143 patients), or tympanic contact thermometer (36 patients). Available potential predictors included American Society of Anesthesiologists status, sex, age, weight, height, body mass index, adipose ratio, and lean body weight. Association with preoperative hypothermia was assessed separately for each predictor using logistic regression. Independent predictors were identified using multivariable logistic regression. MAIN RESULTS: A total of 493 patients were included in the study. Hypothermia was found in 105 patients (21.3%; 95% confidence interval, 17.8%-25.2%). The median core temperature was 36.3 degrees C (25th-75th percentiles, 36.0 degrees C-36.7 degrees C). Two independent factors for preoperative hypothermia were identified: male sex and age (>52years). CONCLUSIONS: As a consequence of the high incidence of hypothermia before anesthesia, measuring core temperature should be mandatory 60 to 120minutes before induction to identify and provide adequate treatment to hypothermic patients. PMID- 27687394 TI - The optimal combination of mechanical ventilator parameters under general anesthesia in obese patients undergoing laparoscopic surgery. AB - OBJECTIVE: Pulmonary dysfunction after laparoscopic surgery is commonly seen in the high-risk group of obese patients. To reduce or avoid this complication caused by an improper combination of mechanical ventilation parameters, we conducted the following trial of 3 factors with 3 levels of mechanical ventilation, aimed to obtain the low airway pressure with good ventilator effects. METHODS: Patients were randomly allocated as a sample of cases according to the "30<=weight/height(2)<40" obesity index. Anesthesia machine was checked on the most fundamental respiratory frequency (f), tidal volume (VT), and respiratory ratio (I:E) as the 3 factors of A, B, and C, with 3 levels of f=15, 12, 9 (beats per minute), VT=8, 10, 12 (mL/kg), and I:E=1:2.5, 1:2.0, 1:1.5. By using L9 (3(4)) K=3 repeat, the orthogonal experimental design and analysis table for statistics, testing, and analysis of the factors that affect the respiratory and change at the end of the level of carbon dioxide (PETCO2), peak airway pressure (PIP), mean airway pressure (Pmean), and the end of endogenous airway pressure (PEEPi) are of statistical significance. SPSS 13.0 analysis of variance was used for statistically significant test, with P<.05 and P<.01 as statistically significant differences. RESULTS: In this study, a total of 27 cases of laparoscopic surgery were allocated in 9 experimental groups under general anesthesia. Patients' vital signs are stable; SPO2 is 100%. There are different combinations among 3 factors and 3 levels of parameters: (1) the impact on the PETCO2, respiratory frequency (f), and/or VT, choose either level, P<.01 means statistically significant, respiratory ratio (I:E) of either selection, P>.05, not statistically significant; (2) the impact of PIP: respiratory frequency (f) change, P<.05, significant difference, VT and I:E changes, P<.01 means statistically significant; (3) the impact of airway pressure on average (Pmean): 3 factors and 3 levels of selected respiratory parameters, P<.01 means statistically significant. CONCLUSION: The best combination of respiratory parameters is A3B1C2, that is, f=9beats per minute, VT=8mL/kg, and I:E=1:2.0. That is, neither small tidal volume and faster frequency nor slow frequency large tidal volume is a good choice. To let obese patients under general anesthesia can obtain a lung protective effect of low airway pressure with good ventilation; it is noteworthy that (1) I:E of airway pressure (PIP, Pmean) is the important impact factor for the protection of the lung and (2) I:E of airway pressure (PIP, Pmean) is the factor with opposite properties. PMID- 27687395 TI - Respiratory volume monitoring in an obese surgical population and the prediction of postoperative respiratory depression by the STOP-bang OSA risk score. AB - STUDY OBJECTIVE: To evaluate use of a respiratory volume monitor (RVM; ExSpiron, Respiratory Motion, Inc., Waltham, MA, USA) that provides minute ventilation (MV), tidal volume (TV) and respiratory rate (RR) measurements in obese surgical patients, hitherto undescribed. DESIGN: Prospective, IRB-approved observational study of RVM parameter accuracy in obese surgical patients, designed to test the ability of the RVM to detect predefined postoperative respiratory depression (PORD) and apneic events (POA) and to correlate STOP-Bang scores with PORD and POA. SETTING: Pre-, intra-, and post-op patient-care areas, including the post anesthesia care unit (PACU) in 2 academic centers with bariatric populations. PATIENTS: 80 patients (47+/-12 years), BMI of 43+/-7 kg/m(2) undergoing elective surgery were enrolled. INTERVENTIONS: Data collected included patient characteristics, STOP-Bang scores and RVM data from immediately preoperatively through PACU completion without effecting standard clinical care. MEASUREMENTS: Low minute ventilation (LMV) was defined as 40% of predicted MV, and PORD was defined as sustained LMV for 5 minutes. Appropriate parametric and non-parametric statistical analyses were performed, P<.05 considered significant. MAIN RESULTS: In 56 patients with complete intraoperative ventilator data, correlation between RVM and ventilator MV measurements was r=0.89 (measurement bias 1.5%, accuracy 11%). Measurement error was 0.13 L/min (95% confidence interval-0.93 L/min - 1.20 L/min). In PACU, 16.3% and 31% of patients had PORD and POA respectively. There were no significant differences in the incidence of PORD and POA in 3 STOP-Bang risk categories (P>.2). CONCLUSIONS: There was excellent correlation and accuracy between the RVM and ventilator volumes in obese surgical patients. A considerable number of patients exhibited PORD and POA in the PACU. The STOP-Bang risk scores correlated poorly with PORD and POA which suggests that obese surgical patients remain at risk for early post-operative respiratory events irrespective of the STOP-Bang score.

PMID- 27687397 TI - Analgesic efficacy of pregabalin in acute postmastectomy pain: placebo controlled dose ranging study. AB - STUDY OBJECTIVE: We hypothesized that oral administration of a single dose of pregabalin 2 hours before modified radical mastectomy (MRM) would produce dose related reduction in postoperative opioid consumption. DESIGN: Prospective randomized controlled clinical trial. SETTING: Postanesthesia care unit. PATIENTS: One hundred twenty adult women scheduled for unilateral (MRM) with axillary evacuation. INTERVENTIONS: Patients were randomized to receive either, placebo capsule, pregabalin 75 mg, pregabalin 150 mg, or pregabalin 300 mg. MEASUREMENTS: The assessment parameters were the postoperative analgesic effect using visual analog scale (VAS) pain scores, the subsequent 24-hour morphine consumption, and the systemic adverse effects of pregabalin doses. MAIN RESULTS: The VAS score at rest and movement was significantly decreased only in group P300 and group P150 in comparison to group P0 and group P75 at 0 hour (P<.01). The median (interquartile range) consumption of morphine in the first postoperative 24 hours was significantly decreased in group P300 in comparison to group P0 and group P75 (P300 vs P0: 6.5 [5-6.5] vs 20.5 [15.8-20.5] [P<.001]; P300 vs P75: 6.5 [5-6.5] vs 20 [14-20] [P<.001]), but there was no significant difference between group P300 and group P150. In addition, there was a significant decrease in consumption of morphine in group P150 in comparison to group P0 and group P75 (P150 vs P0: 7 [5-7] vs 20.5 [15.8-20.5] [P<.001]; P150 vs P75: 7 [5-7] vs 20 [14 20] [P<.001]). There were statistical significant increase in dizziness and blurred vision in group P300 in comparison to other groups (P<.05). CONCLUSIONS: A single preoperative oral dose of pregabalin 150 mg is an optimal dose for reducing postoperative pain and morphine consumption in patients undergoing MRM.

PMID- 27687400 TI - Transorbital endotracheal intubation: a nonstandard approach to a difficult airway. AB - We present the case report of a 49-year-old gentleman with a history of adenoid cystic carcinoma of the left nare status post curative bifrontal craniotomy, left lateral rhinotomy and medial maxillectomy, adjuvant radiotherapy, and orbital exenteration for optic neuropathy, complicated by medial wall dehiscence. His course was also complicated by severe radiation trismus, for which he was scheduled to undergo bilateral mandibular coronoidectomies. Given his limited mouth opening, the surgeon requested a nasal endotracheal tube. Because of concerns of traumatizing his nare, we utilized a flexible fiberoptic bronchoscope to perform asleep transorbital intubation. Airway management in patients with severe trismus may require ingenuity. PMID- 27687401 TI - Pulse oximetry-derived pleth variability index can predict dexmedetomidine induced changes in blood pressure in spontaneously breathing patients. AB - STUDY OBJECTIVE: Hypertension or hypotension in patients receiving continuous infusions of dexmedetomidine (DEX) is often due to changes in vascular resistance caused by alpha2 receptor stimulation. We investigated whether baseline perfusion index (PI) and pleth variability index (PVI), derived from pulse oximetry readings, could predict DEX-induced changes in the hemodynamic status in spontaneously breathing patients. DESIGN: Observational study. SETTING: Operating room. PATIENTS: Patients (American Society of Anesthesiologists performance status 1 or 2) scheduled to undergo lower extremity or abdominal procedures under regional anesthesia were approached. INTERVENTIONS: The PI and PVI were set as baseline upon arrival in theater and were then measured at 2.5-minute intervals. Upon attaining stable hemodynamic status under spontaneous breathing, intravenous administration of DEX was initiated at 6 MUg kg(-1) h(-1) for 10minutes, followed by continuous infusion at 0.6 MUg kg(-1) h(-1). MEASUREMENTS: Blood pressure, heart rate, PI, and PVI were measured. Hypertension was defined as an increase in systolic blood pressure (SBP) >15% and hypotension as a decrease in SBP <15% from baseline. MAIN RESULTS: Baseline PI and PVI correlated with the degree of change in SBP. The maximum percentage increase as well as the maximum percentage of decrease in SBP from baseline correlated with baseline PI (r=0.418 [P=.005] and r=0.507 [P<.001], respectively) and PVI (r=-0.658 [P<.001] and r=-0.438 [P=.003], respectively). PVI <15 identified DEX-induced hypertension (sensitivity 94%, specificity 85%) and PVI >16 identified DEX-induced hypotension (sensitivity 83%, specificity 64%). CONCLUSIONS: PVI may predict DEX-induced changes in blood pressure in spontaneously breathing patients.

PMID- 27687403 TI - A comparison of the effectiveness of the streamlined liner of pharyngeal airway in paralyzed and nonparalyzed patients undergoing gynecological surgery: a randomized trial. AB - STUDY OBJECTIVE: To compare the effectiveness of streamlined liner of pharyngeal airway (SLIPA) in paralyzed and nonparalyzed, anesthetized patients undergoing gynecological surgery. DESIGN: Prospective randomized double-blind clinical trial. SETTING: Intraoperative. PATIENTS: A total of 80 female patients with American Society of Anesthesiologists class I or II and who were undergoing gynecological surgery. INTERVENTIONS: The patients were randomly allocated to either the nonparalyzed group (group NR, n=40) or the paralyzed group (group R, n=40). MEASUREMENTS: Oropharyngeal leakage pressure was the primary outcome. Insertion time; number of insertion attempts; success rate at first insertion; involuntary movement; peak inspiratory pressure (PIP); leakage fraction; hemodynamic changes; complications, such as blood tinging, regurgitation, and sore throat; and recovery time were also evaluated for secondary outcomes. MAIN RESULTS: Oropharyngeal leakage pressure, which is primary outcome, was no difference among the groups. Insertion time, number of insertion attempts, success rate at first insertion, involuntary movement, leakage fraction, hemodynamic changes, and complications were not statistically different among the groups. The PIP in group NR was significantly increased compared to that of group R (P=.002). Recovery time was significantly longer in group R than in group NR (P<.001). CONCLUSIONS: SLIPA had good performance in both paralyzed and nonparalyzed patients. There was no difference in SLIPA performance or complications irrespective of muscle relaxant use, except decrease in PIP and prolong recovery time in paralyzed patients. PMID- 27687404 TI - Fiberoptic nasopharyngoscopy for evaluating a potentially difficult airway in a patient with elevated intracranial pressure. AB - A 62-year-old man with a left temporal lobe tumor was scheduled for a semiurgent craniotomy for tumor excision. Previously, the patient had a laryngeal carcinoma that was resected and treated with chemotherapy and radiotherapy and a history of laryngeal biopsy with awake fiberoptic intubation. Because a difficult airway was anticipated, awake fiberoptic nasopharyngoscopy of the airway was performed under topical anesthesia in the operating room. This revealed a narrow glottic opening with no supraglottic pathology or friable tissue. Based on these airway observations, we proceeded safely with intravenous induction and secured the airway in a controlled fashion, thereby minimizing the risk of increased intracranial pressure and catastrophic complications. Nasopharyngoscopy can be used safely to evaluate the upper airway to stratify airway management in patients with a history of head and neck cancer presenting for neurosurgical procedures in the setting of elevated intracranial pressure. PMID- 27687405 TI - Impact of pillow height on double-lumen endotracheal tube intubation with McGRATH MAC: a prospective randomized clinical trial. AB - STUDY OBJECTIVE: This study aimed to compare the impact of pillow height on double-lumen tracheal tube (DLT) intubation with McGRATH MAC (McG) in patients undergoing elective surgery. DESIGN: Randomized clinical trial. SETTING: Operating room. PATIENTS: Fifty adult patients scheduled for elective surgery under 1-lung ventilation with an American Society of Anesthesiologists physical status of 1 to 3. INTERVENTIONS: DLT intubation with McG was performed with a high pillow (HP group; 25 patients) or low pillow (LP group; 25 patients) by anesthesiologists. MEASUREMENTS: Intubation time, number of laryngoscopy, number of tracheal intubation attempts to successful intubation, percentage of glottic opening score, and subjective difficulty of laryngoscopy and tube passage through the glottis were assessed. MAIN RESULTS: Intubation time was significantly shorter in the HP group compared with the LP group (HP: 32.1+/-14.9seconds vs LP: 49.4+/-11.2seconds, P<.001). The number of laryngoscopy were 1 (HP group, 22 patients; LP group, 17 patients), 2 (HP group, 3 patient; LP group, 7 patients), and 3 (HP group, 0 patient; LP group, 1 patient), with no significant difference between the 2 groups (P=.197). Although the percentage of glottic opening score did not significantly differ between HP and LP groups (HP: 95.6%+/-6.7% vs LP: 96.0%+/-12.3%, P=.08), the number of tracheal intubation attempts was significantly lower in the HP group compared with the LP group (P=.009). The visual analog scale score for laryngoscopy did not significantly differ between the 2 groups (P=.54). However, the visual analog scale for tube passage through the glottis was significantly higher in the LP group than in the HP group (P<.001). CONCLUSIONS: Intubation with an HP was associated with a better DLT intubation profile than with an LP with McG, possibly due to smoother tracheal tube progression through the glottis. PMID- 27687406 TI - Anesthetic considerations for renal transplant surgery in patients with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes syndrome: a case report. AB - Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes syndrome is a progressive syndrome with variable involvement of multiple-organ systems. These patients require special consideration for preoperative optimization, intraoperative management, and postoperative care. The medical literature regarding perioperative management of these patients relies heavily on case reports. Here we present a novel experience providing care for a patient with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes syndrome who underwent renal transplantation for focal segmental glomerulosclerosis and end-stage renal disease.

PMID- 27687409 TI - Evaluating sepsis training for medical students and nonphysicians in Malawi. AB - STUDY OBJECTIVE: This study aimed to evaluate whether (regarding the Surviving Sepsis Campaign [SSC] guidelines) the training of Malawis scarce medical staff is adequate. Hospitals in Malawi have a severe shortage of human resources and therefore rely heavily on junior staff. Sepsis is a leading cause of admission to hospitals particularly in resource poor countries. It is associated with a high mortality rate. The SSC guidelines have been developed to help frontline staff diagnose and treat patients with sepsis. DESIGN: A questionnaire consisting of 10 multiple choice questions, which was to be completed before and after a teaching module. SETTING: Anesthesia courses at the University of Malawi. INTERVENTION: Participants had to answer the questionnaire before and after their teaching block on anesthetics and critical care. The medical students have a 2-week teaching block, and the nonmedical staff have an intensive 3-day training course. MBBS 1 was asked only once as a baseline. PARTICIPANTS: 168 medical students and 31 nonphysician staff returned 345 questionnaires (return rate, 97.1%). MEASUREMENTS: A total of 345 anonymous multiple choice questionnaires were completed. The same questionnaire was then repeated after their teaching block on anesthesia and critical care (not MBBS 1). The aim was for us to assess the knowledge the students had of sepsis. Overall 67% of the questions were answered correctly (2299 correct answers of 3450). The MBBS IV students had an average score of 68% to 72%, and the MBBS I students had a score of 42%. The highest score was achieved by the nonphysician clinical staff after their teaching as they improved by 11% (65%-76%). CONCLUSIONS: Medical students and health care workers have a lack of knowledge regarding the SSC guidelines which needs to be addressed via training. The medical student teaching was not as effective as the nonphysician clinical staff course, and therefore, we need to think about restructuring their teaching block by having an intensive "Sepsis Day" that focuses on the SSC guidelines. PMID- 27687410 TI - Intraocular pressure changes: the McGrath video laryngoscope vs the Macintosh laryngoscope; a randomized trial. AB - STUDY OBJECTIVE: To determine the effects of the McGrath Series 5 video laryngoscope on intraocular pressure (IOP) during laryngoscopy. DESIGN: Prospective, randomized, double blind. SETTING: Operating room. PATIENTS: Eighty adult patients of American Society of Anesthesiologist physical status 1 scheduled for nonophthalmic elective surgery under general anesthesia. INTERVENTIONS: The endotracheal intubation was provided using McGrath series 5 video laryngoscope in MG group (n=40) or Macintosh laryngoscope in M group (n=40). MEASUREMENTS: The IOP of the right and left eyes was measured before and after the laryngoscopic process. MAIN RESULTS: The mean arterial blood pressure values just before laryngoscopy and intubation and after intubation were 77.38+/ 6.18 and 97.38+/-12.77 in the McGrath video laryngoscope group and 75.85+/-7.88 and 99.12+/-14.30 in the Macintosh laryngoscope group, respectively. The IOP values of the left eye after intubation and at the 5th and the 10th minutes in the Macintosh laryngoscope group were found to be significantly higher than those in the McGrath video laryngoscope group (P=.019, P=.019, and P=.007, respectively). In addition, the IOP values of the right eye were found to be higher after intubation and at the 5th and the 10th minutes in the Macintosh laryngoscope group, compared to the McGrath video laryngoscope group (P=.009, P=.021, and P=.011, respectively). The mean IOP values for the left eye just before laryngoscopy and intubation and after intubation were 10.65+/-2.52 and 15.57+/-3.62 in the McGrath video laryngoscope group, and for the right eye, they were 10.60+/-1.64 and 17.17+/-2.38 in the Macintosh laryngoscope group, respectively. CONCLUSION: The McGrath Series 5 video laryngoscope may provide a lower IOP level compared to the Macintosh laryngoscope in an otherwise healthy, young patient population.

AB - STUDY OBJECTIVE: The aim of this study is to compare the analgesic effect of intravenous infusion of magnesium sulfate to ketorolac during laparoscopic surgeries. DESIGN: Double-blind randomized controlled trial. SETTING: University affiliated teaching hospital. PATIENTS: Sixty women submitted to laparoscopic gynecologic oncology surgeries. INTERVENTIONS: Intravenous ketorolac 30 mg in bolus followed by saline infusion (group K), intravenous magnesium sulfate 20 mg/kg in bolus followed by magnesium 2 mg kg(-1) h(-1) (group M) or intravenous saline solution 20 mL in bolus followed by saline infusion during the entire procedure (group S). MEASUREMENTS: Postoperative pain, nausea, vomiting, sedation, opioid consumption, time to first dose of analgesic. MAIN RESULTS: Magnesium sulfate reduced opioid consumption compared with placebo in the postoperative, but not in the intraoperative, period. Nausea, not vomiting, was reduced in ketorolac but not in the magnesium group. Pain intensity was higher in placebo than in the other 2 groups during all periods of observation. In the first 60 minutes, pain intensity was lower in the magnesium than in the ketorolac or the placebo group. CONCLUSION: Intraoperative magnesium sulfate improves postoperative pain control, acting as an opioid-sparing adjuvant, and is similar to ketorolac 30 mg administered in the beginning of surgery. PMID- 27687418 TI - Perioperative course in patients with hereditary or acquired angioedema. AB - PURPOSE: Two types of bradykinin-mediated angioedema, hereditary angioedema (HAE) and acquired angioedema (AAE), result from deficiency or dysfunction of C1 esterase inhibitor, leading to an overproduction of bradykinin, which can lead to vascular permeability and life-threatening angioedema of the airway. The objective of this study was to review perioperative outcomes in a series of patients with HAE and AAE and to review current knowledge about anesthetic complications in patients with HAE or AAE. METHODS: Medical records were retrospectively reviewed for perioperative complications in patients with HAE or AAE who underwent general anesthesia from January 1, 2000, to December 31, 2014, at our institution. RESULTS: Twenty-four patients (13 with HAE, 10 with AAE, and 1 with unspecified angioedema) underwent 38 instances of general anesthesia with airway manipulation. All except 4 received prophylactic therapy. One patient, a 67-year-old woman who was pretreated with stanozolol and fresh frozen plasma required reintubation after postoperative airway edema developed. CONCLUSION: Life-threatening episodes of angioedema of the airway occur infrequently, but they can occur in patients who received pretreatment and in patients who have previously undergone anesthesia uneventfully. Anesthesiologists must be ready to emergently manage a difficult airway and must be familiar with recommendations provided in consensus guidelines for the treatment of HAE and AAE patients.

In conclusion, epidural anesthesia can cause spinal myoclonus, which can be treated with a benzodiazepine. PMID- 27687420 TI - Surgical Apgar score is associated with myocardial injury after noncardiac surgery. AB - STUDY OBJECTIVE: To assess the impact of intraoperative hemodynamics in the development of perioperative myocardial infarction (MI) and myocardial ischemia after noncardiac surgery. DESIGN: Single-center retrospective cohort study of surgical patients from 2007 to 2012. SETTING: Postanesthesia care unit, intensive care unit, and medical-surgical ward at an academic tertiary medical center. PATIENTS: A total of 46,799 adult noncardiac, nonthoracic surgery patients, for which 2290 peak cardiac troponin (cTn) levels were available. MEASUREMENTS: The 10-point Surgical Apgar Score (SAS) was calculated from intraoperative heart rate, blood pressure, and blood loss. Peak troponin (cTn) levels, hospital length of stay, 7- and 30-day postoperative mortality, patient demographics, and prior medical conditions were gathered. Troponin leak was defined as cTn-I 0.6 to 1.5 ng/mL or cTn-T 0.1 to 0.3 ng/mL; perioperative MI criteria were cTn-I greater than 1.5 ng/mL or cTn-T greater than 0.30 ng/mL. MAIN RESULTS: Of 46,799 noncardiac surgical cases, 209 (0.4%) and 192 (0.4%) suffered cTn leak and MI, respectively. Low SAS (0-4) was associated with increased risk of cTn leak and perioperative MI (univariate odds ratio, 2.76 and 2.06; 95% confidence interval, 2.20-3.45 and 1.57-2.70, respectively). In multivariable analysis, Surgical Apgar Score, age 65 years or older, American Society of Anesthesiologists physical status greater than or equal to III, emergency surgery, history of MI or hypertension, prolonged intraoperative tachycardia (heart rate >100 beats/min for >59 minutes), and prolonged hypotension (mean arterial pressure <40 mm Hg for >2 minutes) were independently associated with cTn leak and perioperative MI. CONCLUSIONS: Low SAS scores (0-4) may be associated with cTn elevation after noncardiac surgery. SAS-based risk stratification may guide perioperative cTn surveillance in lieu of routine postoperative screening.

AB - Opioids are important for surgical pain control but may not be appropriate for patients with narcotic abuse histories or opioid intolerance. We describe a laparoscopic bilateral inguinal herniorrhaphy performed without perioperative or postoperative narcotics. Postoperative analgesia involves a novel technique using 2 different bupivacaine formulations that act synergistically to avoid lag time and provide extended pain relief during the acute surgical recovery phase. PMID- 27687422 TI - In vitro antimicrobial activity of commonly used vasoactive drugs. AB - STUDY OBJECTIVE: Microbial contamination during preparation of the infusion drugs is an important issue in intensive care units. Objective of this study was to investigate in vitro antimicrobial properties of commonly used vasoactive drugs. DESIGN: Prospective study. SETTING: Clinical microbiology laboratory of a university hospital. MEASUREMENTS: Growth of the microorganisms Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans in saline dilutions of adrenaline at 1, 10, and 100 MUg/mL; noradrenaline at 1, 10, and 100 MUg/mL; and dopamine at 0.1, 1, and 10 mg/mL concentrations was investigated. Each drug solution and saline were analyzed with a digital pH meter. MAIN RESULTS: Saline dilutions of adrenaline, noradrenaline, and dopamine at clinically used concentrations decreased microbial growth. The highest concentration doses of adrenaline, noradrenaline, and dopamine used in the study had significant antimicrobial effect when compared to the low and moderate doses. This effect was shown with the all microorganisms. S aureus, S epidermidis, and C albicans were more sensitive; on the other hand, E coli and P aeruginosa were more resistant against the effect of the drug dilutions. CONCLUSIONS: To limit microbial growth in case of contamination of the drug solution, it is advisable to use more concentrated dilutions of adrenaline, noradrenaline, and dopamine used in clinical practice.

PMID- 27687425 TI - Using an at-risk salary model to improve throughput in academic medical center operating rooms. AB - STUDY OBJECTIVE: The objective was to analyze if an at-risk salary model for faculty anesthesiologists could improve on-time first case starts (FCSs) and case turnovers (TOs) in an academic hospital inpatient operating room (IOR) and ambulatory surgery center (ASC). Organizational goals were 65% and 70% on-time FCS and case TO times for IOR and ASC, respectively. DESIGN: This was a retrospective study. SETTING: Surgical cases performed at both the IORs and the ASCs at a large academic medical center were included. INTERVENTIONS: We converted 5% to 7% (academic rank dependent) of anesthesiologist salary from guaranteed to an at-risk salary model. Salary was earned back on a case-by-case basis by starting cases on time or by documenting a valid reason for case delay in the anesthesia record. On-time first case and goal TO times were determined using American Association of Clinical Directors standard definitions. MEASUREMENTS: Data were reviewed for 1 year prior to implementation of the at risk salary model and for 1 year after the implementation. Monthly average on time FCS and TO times were compared between the preimplementation and postimplementation time frames. Data were analyzed using analysis of variance for repeated measures. MAIN RESULTS: After the implementation of the at-risk salary model, the organization experienced a 33% and 86% improvement in on-time FCSs (P< .01) in the inpatient and ambulatory operating rooms, respectively. A 41% (IOR) and 44% (ASC) improvement in timely case TOs (P< .01) was also seen. CONCLUSIONS: Anesthesiologists can drive efficiency in an operating room setting. By incentivizing on-time FCS and timely case TO with an at-risk salary model for faculty anesthesiologists, we were able to demonstrate a sustained significant improvement for these metrics. In both an inpatient and an ambulatory setting, operating room efficiency may be best served by aligning provider financial incentives with desired outcome metrics. PMID- 27687426 TI - Noninvasive ventilation during spontaneous breathing anesthesia: an observational study using electrical impedance tomography. AB - STUDY OBJECTIVE: To assess the effects of noninvasive ventilation (NIV) during spontaneous breathing anesthesia on functional residual capacity and ventilation distribution. DESIGN: Prospective and observational study. SETTING: Operating room, military teaching hospital. PATIENTS: Eighteen adult patients submitted to digestive endoscopic procedures under spontaneous breathing anesthesia. INTERVENTIONS: Anesthetic management was standardized. Patients were submitted to combined digestive endoscopic procedures (gastric fibroscopy and colonoscopy) under spontaneous breathing anesthesia in lateral decubitus position. Anesthesia was induced with propofol intravenous 1 mg/kg. Repeated boluses of propofol were administered according to the patients' clinical needs during endoscopic procedures. Ventilation distribution and functional residual capacity were assessed by electrical impedance tomography. MEASUREMENTS: Ventilation distribution was assessed by electrical impedance changes in left and right lung, and functional residual capacity changes were evaluated by measurement of end expiratory lung impedance changes. Measures were performed before anesthesia induction, 5 minutes after anesthesia induction during gastric fibroscopy, at the end of gastric fibroscopy, 5 minutes after NIV application during colonoscopy, and at the end of colonoscopy. MAIN RESULTS: In awake patients, tidal volume was primarily distributed to the dependent lung (57.5% vs 43.1%; P=.009). After anesthesia induction, we observed a shift of ventilation to the nondependent lung (43.1% before anesthesia, 58.9% after anesthesia; P=.002) and marked decrease in end-expiratory lung impedancemetry of -1.68UI (4.47). Noninvasive ventilation application resulted in a significant increase of end-expiratory lung impedancemetry of 1.33 (6.49) (P=.005) but did not impact ventilation distribution. CONCLUSIONS: This study showed that NIV application in pressure support mode during spontaneous breathing anesthesia increased functional residual capacity. Other studies are needed to evaluate the clinical impact of this technique during anesthesia, especially in patients with poor respiratory conditions. PMID- 27687427 TI - The effect of serratus plane block performed under direct vision on postoperative pain in breast surgery. AB - STUDY OBJECTIVES: To determine the effectiveness of serratus plane block performed under direct vision on postoperative pain after mastectomy. DESIGN: We performed a retrospective study of elective breast surgery patients undergoing mastectomy over 6 months. We collected data on the outcomes for the pain score and use of analgesia in recovery, the use of analgesia and antiemetics overnight, and the pain score and mobilization status of the patient 1 day after the operation. SETTING: Breast cancer is the most common cancer in women, and mastectomy is commonly performed as part of the management. A mastectomy can cause significant acute pain which progresses to chronic pain in 25% to 60% of women. Recent studies have suggested that a serratus plane block is a viable alternative to regional anesthetic techniques without the side effect profile and that injection of local anesthetic into serratus anterior provided predictable and effective anesthesia to the chest wall. Serratus blocks target the thoracic nerves more selectively than pectoral blocks, and local blocks can reduce the use of opiates postoperatively thereby lessening opiate-related side effects. PATIENTS: Our sample included 16 patients who had received a serratus block and 11 patients who only had wound infiltration with levobupivacaine with adrenaline and clonidine. INTERVENTION: Serratus plane block was conducted by injecting 50% of the totally available levobupivacaine 0.375% with adrenaline and clonidine deep to serratus anterior under direct observation. MAIN RESULTS: No patients receiving a serratus block suffered severe pain in recovery or day 1 postoperatively. Patients receiving wound infiltration alone had 2 patients suffering severe pain in recovery and 3 patients suffering severe pain day 1 postoperatively. CONCLUSION: Serratus block provides effective regional anesthesia, suitable for mastectomies, and currently appears to be superior to wound infiltration alone. However, further data will need to be collected to support this finding. PMID- 27687428 TI - Bilateral tension pneumothorax during colonoscopy in a patient with chronic obstructive pulmonary disease: a case report. AB - Colonoscopy is widely performed for the diagnosis and treatment of various colonic disorders and the screening and surveillance of colorectal neoplasia. According to research evidence, up to one-third of patients had at least 1 minor and transient gastrointestinal symptom after colonoscopy. Although severe complications developed uncommonly, they are potentially serious and life threatening. Here, we present the case of a 95-year-old man with chronic obstructive pulmonary disease who developed bilateral tension pneumothorax during therapeutic colonoscopy for sigmoid volvulus. In this case, air trapping resulting from the Valsalva maneuver under inadequate pain control may be the mechanism for fatal tension pneumothorax during colonoscopy.

Despite adequate dosing of both intravenous and inhalation anesthetics, our patient was resistant to induction of the state of general anesthesia. Subsequently, we noticed extreme hyperlipidemia. We hypothesized that the patient's extreme hyperlipidemia served as an anesthetic "sink" and prevented the full dose of intravenous agents from quickly reaching their intended site of action. PMID- 27687431 TI - Different interventions in preventing opioid-induced cough: a meta-analysis. AB - BACKGROUND: Cough is one of the most common complications of opioids. Many studies have evaluated the effect of various drugs in preventing opioid-induced cough (OIC). However, there is existing controversy about those reports. The present study was performed to assess the efficacy of different interventions on OIC. METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, and Embase to identify randomized controlled trials on the efficacy of different drugs in the prevention of OIC. Opioids included fentanyl, sufentanil, and remifentanil. We mainly investigated the incidence and severity of OIC after different interventions. RESULTS: Thirty-four trials including 9906 patients were analyzed in this study. Twenty different drugs were reported, and 10 drugs were indentified in more than 2 articles. These drugs, including lidocaine, ketamine, dexmedetomidine, priming of fentanyl, propofol, dezocine, dexamethasone, dextromethorphan, and magnesium sulfate (MgSO4), showed a significant efficacy compared with controls. There were insufficient numbers of trials for salbutamol, clonidine, tramadol, pentazocine, rocuronium, midazolam, atropine, terbutaline, sodium chromoglycate, beclomethasone, and ephedrine. From these data, we found that salbutamol, tramadol, midazolam, and atropine were ineffective. CONCLUSIONS: This meta-analysis suggested that the prophylactic administration of lidocaine, ketamine, dexmedetomidine, priming of fentanyl, propofol, and dezocine was effective in preventing OIC.

PMID- 27687433 TI - Individualized remediation during fellowship training. AB - The Accreditation Council for Graduate Medical Education requires medical training programs to monitor, track, and formally document a fellow's performance. If deficiencies are found, programs are expected to prepare and implement an effective plan of action for improvement and to ensure that graduates acquire the personal and professional attributes of an independent physician. We revised our evaluation policy and instituted a remediation protocol in 2008. Since that time, 130 pediatric anesthesia fellows have graduated. Seven fellows (5%) underwent departmental formal consultation for deficient behavior or poor performance. Of these 7 fellows, 4 underwent an individualized remediation program (IRP). A formal performance review and written contract, with specifically identified problems and general themes, recommendations for time based successful behaviors, and clearly identified consequences for unsuccessful behaviors, was initiated for each fellow undergoing an IRP. All fellows who participated in this program completed their subspecialty training in pediatric anesthesia, and all eligible fellows have successfully achieved their subspecialty board certification. Our approach has the advantage of multimodality, time-based daily evaluations, and group discussions in the context of a Clinical Competency Committee. Utilization of an IRP as a metric for progress has features similar to effective cognitive behavioral therapy contracts and has ensured that our graduates are held to clearly delineated and specified skills and behaviors that allow them to work independently in the field of pediatric anesthesiology. PMID- 27687434 TI - Efficacy of palonosetron in postoperative nausea and vomiting (PONV)-a meta analysis. AB - INTRODUCTION: Palonosetron is a second-generation 5-HT3 receptor antagonist with proposed higher efficacy and sustained action for prophylaxis of postoperative nausea and vomiting (PONV). METHODS: Randomized controlled trials involving adult population undergoing elective surgery under general anesthesia comparing palonosetron to placebo, ramosetron, granisetron, and ondansetron were included. Data were extracted for vomiting incidence (VI), complete response (no nausea/vomiting; Complete Response [CR]), and rescue antiemetic need. This was categorized as early phase (24 hours postoperative for ramosetron and 6 hours for rest) and delayed phase (48 hours for ramosetron and 24 hours for rest). VI and CR were used as markers of drug efficacy. Any adverse effects were evaluated. RESULTS: Twenty-two trials (4 with 3 groups) were included (comparing palonosetron to placebo in 5, ramosetron in 5, granisetron in 4, and ondansetron in 12 subgroups). Palonosetron demonstrated statistical superiority over placebo for VI and CR, both early/delayed PONV prevention. For delayed phase, palonosetron surpassed ramosetron in all 3 variables; however, none of the variables attained statistical significance during early phase. In early phase, palonosetron had better VI and CR than did granisetron; however, variables other than CR (better for palonosetron) failed to achieve statistical significance for delayed phase. All 3 outcomes were significantly better for palonosetron compared with ondansetron in delayed phase, but statistical superiority could only be demonstrated for VI in early phase. Being inconsistently documented across trials, nausea scores could not be evaluated. CONCLUSION: Palonosetron is as safe as and more effective than placebo, ramosetron, granisetron, and ondansetron in preventing delayed PONV. For early PONV, it has higher efficacy over placebo, granisetron, and ondansetron. PMID- 27687435 TI - King Vision video laryngoscope versus Lightwand as an intubating device in adult patients with Mallampatti grade III and IV patients. AB - STUDY OBJECTIVE: Anticipated and unanticipated difficult airways are often encountered by anesthesiologists in their clinical practice. There are various devices available in such situations. We aim to compare King Vision video laryngoscope and Lightwand for their performance as an intubating device in predicted difficult intubation. DESIGN: Prospective, randomized, single blind study. SETTING: Jawaharlal Nehru Medical College. PATIENTS: Sixty ASA 1 and 2 with Mallampati grade III and IV. INTERVENTIONS: Patients were divided into 2 groups of 30 patients each. Patients of King Vision group [n=30] and Lightwand group [n=30] were intubated using respective devices. Primary outcome measure was time taken to intubate whereas secondary outcome measure ware number of attempts for intubation, no of adjustment maneuvers, changes in heart rate and mean arterial pressure and airway trauma. MEASUREMENTS AND MAIN RESULTS: Mean intubation time using King Vision video laryngoscope (19.50+/-6.73 seconds was lower than the intubation time using Lightwand 25.40+/-7.42 s, P=.00). The difference between number of attempts, success of intubation, numbers of adjustment maneuvers were comparable. There was a significant rise in heart rate within the groups from the pre-induction values. However inter group variations were similar. In addition, there was a significant rise in mean arterial pressure within the groups from the pre-induction values. Inter group variations show less increase in mean arterial pressure with Lightwand at immediate post intubation (P=.0234) and at 3 min and 5 min post intubation anesthesia.

AB - STUDY OBJECTIVE: Acute postoperative pain may transition to persistent/chronic pain in up to 50% or more of patients after certain surgeries. Despite this concern, it is unclear that patients' preprocedure understanding and expectations are aligned with these potential outcomes. This study was designed to evaluate the extent of this alignment and the potential impact on the quality of risk/benefit discussions before procedures. DESIGN: Prospective survey. SETTING: A large, tertiary care preoperative assessment clinic. PATIENTS: A total of 1481 adult patients. INTERVENTIONS: Survey administration. MEASUREMENTS: The survey items evaluated patients' expectations of postoperative pain and how familiar patients were with the risk of persistent postsurgical pain based on their specific characteristics and procedure type. MAIN RESULTS: The overwhelming majority (80%) of patients were unaware of the risk of persistent postsurgical pain. Given the choice, most patients (65%) wanted to be informed of their risk, and 25% stated that it might even affect their decision to proceed with surgery. CONCLUSIONS: There is great need for health care providers to discuss the significant risk of persistent postsurgical pain with patients in the preoperative setting. Patients need to be armed with realistic data to ensure high-quality discussions of risk/benefit, align expectations with outcomes, and potentially identify high-risk groups in which preoperative intervention can reduce the likelihood or severity of persistent postoperative pain syndromes. PMID- 27687439 TI - "Are We hurting ourselves?" What is the prevalence of back pain in anesthesia providers? AB - STUDY OBJECTIVE: Back injuries are a highly reported category of occupational injury in the health care setting. The daily clinical activities of an anesthesia provider, including lifting, pushing stretchers, transferring patients, and bending for procedures, are risk factors for developing low back pain. The purpose of this study is to investigate the prevalence of work related low back pain in anesthesia providers. DESIGN/SETTING: We conducted a cross-sectional survey study of anesthesia providers at an academic institution. PATIENTS: The target population included all 141 clinical anesthesia providers employed by the Penn State Milton S. Hershey Medical Center Department of Anesthesia. INTERVENTIONS: A survey study was conducted using the Oswestry Disability Index (ODI), a validated scoring system for low back pain. Additional questions related to the daily activities of clinical anesthesia practice were also asked. The survey instrument underwent pretesting and clinical sensibility testing to ensure validity and consistent interpretation. MEASUREMENTS: The primary self-reported measures were the prevalence of low back pain in anesthesia providers and an assessment of disability based on the ODI. Secondary functional measures included the impact of low back pain on work flow. MAIN RESULTS: Nearly half (46.6%) of respondents suffer from low back pain attributed to clinical practice. In this subset of respondents, 70.1% reported not having back pain prior to their anesthesia training. Of those with low back pain, 44% alter their work flow, and 9.8% reported missing at least one day of work. Six providers (5.3%) required surgical intervention. Using the ODI score interpretation guidelines, 46% of respondents had a "mild disability" and 2% had a "moderate disability." Respondents reporting feeling "burned out" from their job had a significantly higher average ODI score compared to those who did not (6.8 vs 3.3, respectively; P=.01). CONCLUSIONS: Nearly half of all anesthesia providers sampled suffer from low back pain subjectively attributed to their clinical practice. This leads to changes in work flow and missed days of work. The results of this study suggest a deficiency in the effectiveness of anesthesia training programs in teaching proper techniques to prevent musculoskeletal injuries.

AB - STUDY OBJECTIVE: To determine the most effective time interval between remifentanil and propofol (TimeRP) for the prevention of propofol injection pain in association with remifentanil dosage. DESIGN: Prospective randomized study. SETTING: Operating room of a university hospital. PATIENTS: Sixty American Society of Anesthesiologists physical status 1 and 2 patients scheduled for elective surgery under general anesthesia. INTERVENTIONS: Patients were randomly assigned to 1 of 3 groups to receive remifentanil at dosages of 0.25, 0.5, or 0.75 MUg/kg over 30 seconds before the injection of 1% propofol 2 mg/kg. TimeRP was defined as the time interval from the initiation of the remifentanil injection to the initiation of the propofol injection. TimeRP for each subsequent patient was determined by the response of the previous patient using an up-and down sequential allocation method. Injection pain caused by propofol was evaluated using a 4-point scale during the propofol injection. MEASUREMENTS: TimeRP50 was defined as the TimeRP at which propofol injection pain was absent in 50% of patients, and it was estimated using isotonic regression for each dose group. MAIN RESULTS: TimeRP50 was significantly lower in the remifentanil 0.75 MUg/kg group (38.6 seconds, 83% confidence interval [CI], 35.6-45.0) than in the 0.5 MUg/kg group (65.0 seconds; 83% CI, 52.5-75.0) or the 0.25 MUg/kg group (66.6 seconds; 83% CI, 57.1-76.5). CONCLUSIONS: The efficacy of remifentanil pretreatment for preventing propofol injection pain can be influenced by the time interval between remifentanil and propofol as well as the remifentanil dose.

PMID- 27687445 TI - Incidence of acute kidney injury after elective lower limb arthroplasty. AB - STUDY OBJECTIVE: The aim of this study was to establish the incidence of acute kidney injury (AKI) in patients undergoing elective hip and knee arthroplasty. DESIGN: This was a retrospective cohort study. SETTING: The study was conducted in a district general hospital in the United Kingdom. PATIENTS: All patients undergoing elective hip and knee arthroplasty over a period of 6 months were included in the study. MEASUREMENT: Preoperative and postoperative serum creatinine concentration was recorded in all patients. AKI was defined according to the Acute Kidney Injury Network classification as an increase of serum creatinine concentration of >26.5 MUmol/L (>=0.3 mg/dL) or increase to 1.5-fold from baseline. MAIN RESULTS: Three hundred thirty-seven patients were included in the study. Forty-eight had preexisting stage 3 chronic kidney disease (CKD). The overall incidence of AKI in our study was 6.2%. The incidence in patients with preexisting stage 3 CKD (estimated glomerular filtration rate <60 mL/[min 1.73 m(2)]) was 16.3%, whereas in patients without preexisting stage 3 CKD, the incidence was 4.5%. CONCLUSION: We identified stage 3 or higher CKD as a major risk factor for developing postoperative AKI. Preexisting CKD raised the risk of developing AKI 4-fold. We recommend that all patients undergoing lower limb arthroplasty should have renal function assessed preoperatively. In the perioperative period, renal function should be monitored in all patients. This is of particular importance in patients with estimated glomerular filtration rate <60.

PMID- 27687447 TI - The risk factors of intraoperative anesthesia adverse events in children with laryngeal diseases. AB - BACKGROUND: This study aimed to investigate the risk factors of intraoperative anesthesia adverse events (IAAEs) in children with laryngeal diseases. METHODS: We retrospectively recruited 118 children with laryngeal diseases who underwent surgical therapy. Based on medical history and preoperative imaging diagnosis, the baseline data, including sex, age, weight, onset age, the number of operation, the degree of airway obstruction, the nature of disease, the location of disease, complications, tracheotomy, and trachea intubation, were defined and recorded. IAAEs, such as pulse oxygen saturation (SpO2) decline, heart rate (HR) decline, emergency orotracheal intubation, emergency tracheotomy, and remaining intubated postoperatively, were also recorded. The risk factors for IAAEs were identified using multivariate logistic regression model. RESULTS: Increasing severity of airway obstruction and the presence of pneumonia were risk factors for SpO2 and HR decline in children with laryngeal diseases. Older age, supraglottic rather than subglottic disease, and trachea intubation rather than unprotected airway during surgery were protective factors for SpO2 decline. Furthermore, severe airway obstruction increased risks of emergency orotracheal intubation and remaining intubated postoperatively, whereas supraglottic rather than subglottic disease were protective factors for emergency orotracheal intubation and remaining intubated postoperatively. Only HR decline was found to be associated with the presence of congenital heart disease. CONCLUSIONS: The severe airway obstruction increases the risk of SpO2 decline and HR decline as well as the possibility of perioperative emergency orotracheal intubation and remaining intubated postoperatively, whereas supraglottic surgery and surgery performed under endotracheal intubation reduce the incidence rates of these IAAEs in children with laryngeal diseases. PMID- 27687448 TI - The effect of obesity on the anatomical relationship of the popliteal artery and tibial nerve in the proximal and distal popliteal fossa: relevance to popliteal sciatic nerve block and a traceback technique using the popliteal artery. AB - STUDY OBJECTIVE: To determine the effect of body mass index (BMI) on the relationship of the popliteal artery to the sciatic and tibial nerves in the popliteal fossa. DESIGN: Prospective, observational study. SETTING: University medical center. SUBJECTS: One hundred patients scheduled for magnetic resonance imaging scans of the knee. MEASUREMENTS: BMI was recorded and magnetic resonance imaging scans were assessed at 3 different measurement points along the femur for the distance and angle between the popliteal artery and tibial nerve, or sciatic nerve if the sciatic nerve had not bifurcated at the measurement point. MAIN RESULTS: At the distal femur, the tibial nerve was a mean of 2.9 mm from the popliteal artery. The nerve was consistently posterior to the artery; however, it was variably located medial or lateral to the artery. At the 5- and 8-cm measurement points, the nerve was 10.0 and 16.1 mm (SD, 4.1 and 5.2 mm), and 31 degrees and 44 degrees (SD, 15 degrees and 16 degrees ) lateral to the popliteal artery, respectively. Zero degree was defined as directly posterior to the artery. Increasing BMI was correlated with increasing distance between the nerve and the artery at the 5- and 8-cm measurement points (r= 0.36 P> |t| .000 and .45 P> |t| .002). CONCLUSIONS: At 5 cm proximal to the distal femoral condyles, the popliteal artery is a reliable sonographic landmark to locate the tibial nerve due to the close proximity and consistent location of the nerve 1 cm posterolateral to the artery, with only a moderate effect of BMI. PMID- 27687449 TI - Active perioperative patient warming using a self-warming blanket (BARRIER EasyWarm) is superior to passive thermal insulation: a multinational, multicenter, randomized trial. AB - STUDY OBJECTIVE: Incidence of inadvertent perioperative hypothermia is still high; therefore, present guidelines advocate "prewarming" for its prevention. Prewarming means preoperative patient skin warming, which minimizes redistribution hypothermia caused by induction of anesthesia. In this study, we compared the new self-warming BARRIER EasyWarm blanket with passive thermal insulation regarding mean perioperative patient core body temperature. DESIGN: Multinational, multicenter randomized prospective open-label controlled trial. SETTING: Surgical ward, operation room, postanesthesia care unit at 4 European hospitals. PATIENTS: A total of 246 adult patients, American Society of Anesthesiologists class I to III undergoing elective orthopedic; gynecologic; or ear, nose, and throat surgery scheduled for 30 to 120 minutes under general anesthesia. INTERVENTIONS: Patients received warmed hospital cotton blankets (passive thermal insulation, control group) or BARRIER EasyWarm blanket at least 30 minutes before induction of general anesthesia and throughout the perioperative period (intervention group). MEASUREMENTS: The primary efficacy outcome was the perioperative mean core body temperature measured by a tympanic infrared thermometer. Secondary outcomes were hypothermia incidence, change in core body temperature, length of stay in postanesthesia care unit, thermal comfort, patient satisfaction, ease of use, and adverse events related to the BARRIER EasyWarm blanket. MAIN RESULTS: The BARRIER EasyWarm blanket significantly improved perioperative core body temperature compared with standard hospital blankets (36.5 degrees C, SD 0.4 degrees C, vs 36.3, SD 0.3 degrees C; P<.001). Intraoperatively, in the intervention group, hypothermia incidence was 38% compared with 60% in the control group (P=.001). Postoperatively, the figures were 24% vs 49%, respectively (P=.001). Patients in the intervention group had significantly higher thermal comfort scores, preoperatively and postoperatively. No serious adverse effects were observed in either group. CONCLUSIONS: Perioperative use of the new self-warming blanket improves mean perioperative core body temperature, reduces the incidence of inadvertent perioperative hypothermia, and improves patients' thermal comfort during elective adult surgery.

PMID- 27687451 TI - Successful recovery after amniotic fluid embolism in a patient undergoing vacuum assisted vaginal delivery. AB - Amniotic fluid embolism (AFE) is a rare, catastrophic emergency that requires prompt recognition and treatment. Despite early recognition and supportive therapy, the morbidity and mortality remain high. We report a case of AFE after vacuum-assisted vaginal delivery resulting in hemodynamic collapse and subsequent multiorgan failure. Management included mechanical ventilation, extracorporeal membrane oxygenation, and continuous veno-venous hemodialysis. The patient was able to make a full recovery with minimal sequelae. In AFE with multiorgan failure, extracorporeal membrane oxygenation and continuous veno-venous hemodialysis can be valuable therapies. Proper management requires effective communication and the combined efforts of physicians of several disciplines. PMID- 27687452 TI - Effect of Boussignac continuous positive airway pressure ventilation on Pao2 and Pao2/Fio2 ratio immediately after extubation in morbidly obese patients undergoing bariatric surgery: a randomized controlled trial. AB - STUDY OBJECTIVE: Pathophysiological changes after laparoscopic Roux-en-Y gastric bypass may increase the risk of pulmonary complications in morbidly obese patients. The purpose of the study was to assess the impact of immediate postextubation use of Boussignac continuous positive airway pressure (CPAP) on arterial oxygenation in morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass. The hypothesis is that the use of CPAP may improve oxygenation in the postoperative period when compared to Venturi mask. DESIGN: Randomized controlled study. SETTING: A tertiary referral hospital. PATIENTS: Recruited morbidly obese adult patients undergoing laparoscopic Roux-en-Y gastric bypass. INTERVENTIONS: Boussignac CPAP or Venturi mask was randomly applied immediately after extubation in the operating room and was maintained during the first 2 hours in the recovery room. MEASUREMENTS: Pao2 and Pao2/fraction of inspired oxygen (Fio2) ratio values were measured preoperatively and at 1 (T1), 2 (T2), and 24 hours (T24) after extubation, through arterial blood samples. Secondary outcomes (spirometric parameters) were measured at the same periods. For comparison between groups, Student t test, Mann-Whitney U nonparametric test, and chi(2) test were used. Statistical significance is at P < .05. MAIN RESULTS: Twenty-four patients were included, 12 in each group. There were no differences in preoperative evaluation. There were significant differences between groups in Pao2 and Pao2/Fio2 mean values at T1, T2, and T24, being superior in the Boussignac group. During the 24 hours postextubation, 9% of patients in the Boussignac group and 50% in the Venturi group had a Pao2 less than 60 mm Hg in at least 1 of the evaluations. After extubation, a Pao2/Fio2 ratio value less than 300 was observed in all patients in the Venturi group and in 55% in Boussignac group in at least 1 of the evaluations. There were no differences in spirometric parameters between groups at T1, T2, and T24. CONCLUSIONS: Application of Boussignac CPAP for 2 hours after extubation improved oxygenation but did not improve forced expiratory volume at 1 second and forced vital capacity. PMID- 27687453 TI - Delayed onset and long-lasting hemidiaphragmatic paralysis and cranial nerve deficit after interscalene nerve block for rotator cuff repair in beach chair position. AB - Hemidiaphragmatic paralysis is the most common adverse effect associated with interscalene block. In most cases, it resolves with the resolution of nerve blockade with only an estimated incidence of 0.048% persisting for longer duration. Occasionally, interscalene block is also associated with recurrent laryngeal nerve block and seldom with cranial nerve paresis. We present a case of delayed onset and prolonged hemidiaphragmatic paralysis that was associated with 3 cranial nerve deficits after interscalene nerve block for shoulder surgery performed under general anesthesia in the beach chair position. Etiology is unclear, but most likely multifactorial. PMID- 27687455 TI - Risk stratification, perioperative and periprocedural management of the patient receiving anticoagulant therapy. AB - As a result of the aging US population and the subsequent increase in the prevalence of coronary disease and atrial fibrillation, therapeutic use of anticoagulants has increased. Perioperative and periprocedural management of anticoagulated patients has become routine for anesthesiologists, who frequently mediate communication between the prescribing physician and the surgeon and assess the risks of both thromboembolic complications and hemorrhage. Data from randomized clinical trials on perioperative management of antithrombotic therapy are lacking. Therefore, clinical judgment is typically needed regarding decisions to continue, discontinue, bridge, or resume anticoagulation and regarding the time points when these events should occur in the perioperative period. In this review, we will discuss the most commonly used anticoagulants used in outpatient settings and discuss their management in the perioperative period. Special considerations for regional anesthesia and interventional pain procedures will also be reviewed. PMID- 27687454 TI - Dexmedetomidine acts as an oxidative damage prophylactic in rats exposed to ionizing radiation. AB - STUDY OBJECTIVE: To investigate the effects of dexmedetomidine on oxidative injury caused by ionizing radiation. DESIGN: Randomized controlled experimental study. SETTING: Department of radiation oncology and research laboratory of an academic hospital. INTERVENTIONS: Twenty-eight rats were randomized to 4 groups (n=7 per group). Group S rats were administered physiologic serum; group SR rats were administered physiologic serum and 10 Gy external ionizing radiation. Groups D100 and D200 were administered 100 and 200 MUg/kg dexmedetomidine intraperitoneally, respectively, 45 minutes before ionizing radiation. MEASUREMENTS: Liver, kidney, lung, and thyroid tissue and serum levels of antioxidant enzymes (glutathione peroxidase [GPX], superoxide dismutase, and catalase) and oxidative metabolites (advanced oxidation protein products, malondialdehyde, and nitrate/nitrite, and serum ischemia-modified albumin) were measured 6 hours postprocedure. MAIN RESULTS: In group SR, IR decreased antioxidant enzyme levels and increased oxidative metabolite levels (P<.05). In plasma, antioxidant enzyme levels were higher and oxidative metabolite levels were lower in groups D100 and D200 than in group SR (P<.01). In tissues, hepatic and lung GPX levels were higher in groups D100 and D200 than in group SR (P<.001). Renal and thyroid GPX levels were higher in D200 than in group SR (P<.01). Thyroid superoxide dismutase levels were higher in groups D100 and D200 than in group SR (P<.01). Renal, lung, and thyroid catalase levels were higher in group D200 than in group SR (P<.01). Hepatic, renal, and lung advanced oxidation protein products and malondialdehyde levels were lower in groups D100 and D200 than in group SR (P<.01). Hepatic, renal, and lung nitrate/nitrite levels were lower in group D200 than in group SR (P<.05). CONCLUSIONS: Dexmedetomidine preserves the antioxidant enzyme levels and reduces toxic oxidant metabolites. Therefore, it can provide protection from oxidative injury caused by ionizing radiation. PMID- 27687456 TI - Comparison of esophageal Doppler and plethysmographic variability index to guide intraoperative fluid therapy for low-risk patients undergoing colorectal surgery. AB - STUDY OBJECTIVE: This study aims to investigate if there is equivalence in volumes of fluid administered when intravenous fluid therapy is guided by Pleth Variability Index (PVI) compared to the established technology of esophageal Doppler in low-risk patients undergoing major colorectal surgery. DESIGN: Randomized controlled trial. SETTING: Operating room. PATIENTS: Forty low-risk patients undergoing elective colorectal surgery. INTERVENTION: Patients were monitored by esophageal Doppler and PVI probes and were randomized to have fluid therapy directed by using one of these technologies, with 250 mL boluses of colloid to maintain a maximal stroke volume, or a PVI of less than 14%. MEASUREMENTS: Absolute volumes of fluid volumes given intraoperatively were measured as were 24 hours fluid volumes. Perioperative measurements of lactate and base excess were recorded as were postoperative complications. MAIN RESULT: There was no significant difference between PVI and esophageal Doppler groups in mean total fluid administered (1286 vs 1520 mL, P=.300) or mean intraoperative fluid balance (+839 v+1145 mL, P=.150). CONCLUSIONS: PVI offers an entirely non invasive alternative for goal-directed fluid therapy in this group of patients. PMID- 27687457 TI - Seldinger technique for nasal intubation: a case series. AB - Nasotracheal intubation can be both challenging and traumatic, especially in cases of atypical anatomy. We present a series of 3 such cases in which an endotracheal tube introducer (bougie) was used to facilitate successful, atraumatic, nasotracheal intubation via Seldinger technique. The technique described can guide a nasotracheal tube through narrow nasal passages, small pharyngeal spaces, and past acute laryngeal approach angles, all without transoral manipulation of the tube. The technique is easy to perform, uses a routine skill set, and can be advantageous in numerous clinical scenarios. PMID- 27687458 TI - Difficult mask ventilation: simple step to make the impossible, possible! AB - Mask ventilation is one of the most important skills in airway management. Difficulty in mask ventilation can become life threatening if it is associated with difficulty in intubation during general anesthesia. We report a potential impossible ventilation condition which was safely and easily overcome with appropriate innovative modification of an Opsite adhesive film.

AB - STUDY OBJECTIVE: Neuraxial blockade may increase external cephalic version (ECV) success rates. This survey aimed to assess the frequency and characteristics of neuraxial blockade used to facilitate ECV. SETTING AND DESIGN: We surveyed Society for Obstetric Anesthesia and Perinatology members regarding ECV practice using a 15-item survey developed by 3 obstetric anesthesiologists and tested for face validity. The survey was e-mailed in January 2015 and again in February 2015 to the 1056 Society of Obstetric Anesthesiology and Perinatology members. We present descriptive statistics of responses. PARTICIPANTS: Our survey response rate was 322 of 1056 (30.5%). MAIN RESULT: Neuraxial blockade was used for ECV always by 18 (5.6%), often by 52 (16.1%), sometimes by 98 (30.4%), rarely by 78 (24.2%), and never by 46 (14.3%) of respondents. An anesthetic sensory block target was selected by 141 (43.8%) respondents, and analgesic by 102 (31.7%) respondents. Epidural drug doses ranged widely, including sufentanil 5-25 MUg; lidocaine 1% or 2% 10-20 mL, bupivacaine 0.0625% to 0.5% 6-15 mL, and ropivacaine 0.2% 20 mL. Intrathecal bupivacaine was used by 182 (56.5%) respondents; the most frequent doses were 2.5 mg used by 24 (7.5%), 7.5 mg used by 35 (10.9%), and 12 mg used by 30 (9.3%). CONCLUSIONS: Neuraxial blockade is not universally offered to facilitate ECV, and there is wide variability in neuraxial blockade techniques, in drugs and doses administered, and in the sensory blockade (anesthetic or analgesic) targeted. Future studies need to evaluate and remove barriers to allow for more widespread use of neuraxial blockade for pain relief and to optimize ECV success rates. PMID- 27687461 TI - National Survey of US academic anesthesiology chairs on clinician wellness. AB - STUDY OBJECTIVE: The prevalence of anesthesiology department wellness programs is unknown. A database of wellness programs is needed as a resource for departments attempting to respond to the Accreditation Council for Graduate Medical Education Anesthesiology Milestones Project. The purpose of this study was to survey academic anesthesiology chairs on wellness issues, characterize initiatives, and establish wellness contacts for a Wellness Initiative Database (WID). DESIGN: An Internet-based survey instrument was distributed to academic anesthesiology department chairs in the United States. SETTING: On-line. PATIENTS: None. INTERVENTIONS: None. MEASUREMENTS: Analysis for continuous variables used standard means, modes, and averages for individual responses; 95% confidence intervals for proportions were calculated by Wilson's method. MAIN RESULTS: Seventy-five (56.4%) responses (of a potential 133 programs) were obtained. Forty one (of 71 responders; 57.8%) expressed interest in participating in a WID, and 33 (44%) provided contact information. Most (74.7%) had recently referred staff for counseling or wellness resources, yet many (79.5% and 67.1%, respectively) had never surveyed their department's interest in wellness resources. Thirty-four percent had a wellness resources repository. Of 22 wellness topics, 8 garnered >60% strong interest from respondents: Addiction Counseling, Sleep Hygiene, Peer Support Program, Stress Management, Conflict Management, Burnout Counseling, Time Management, and Dealing with Adverse Events Training. There was a statistically significant difference in interest between those willing to participate or not in the WID across most topics but no significant difference based on need for recent staff referral. CONCLUSIONS: The majority of chairs needed to recently refer a department member to wellness resources or counseling. Most were interested in participating in a WID, whereas a minority had gauged staff interest in wellness topics or had a wellness resource repository. Highest interest was in topics most related to function as an anesthesiologist. Those willing to participate in the database had statistically significant differences in interest across most wellness topics. PMID- 27687462 TI - An in vitro evaluation of the pressure generated during programmed intermittent epidural bolus injection at varying infusion delivery speeds. AB - STUDY OBJECTIVE: Programmed intermittent bolus injection of epidural anesthetic solution results in decreased anesthetic consumption and better patient satisfaction compared with continuous infusion, presumably by better spread of the anesthetic solution in the epidural space. It is not known whether the delivery speed of the bolus injection influences analgesia outcomes. The objective of this in vitro study was to determine the pressure generated by a programmed intermittent bolus pump at 4 infusion delivery speeds through open ended, single-orifice and closed-end, multiorifice epidural catheters. DESIGN: In vitro observational study. SETTING: Not applicable. PATIENTS: Not applicable. INTERVENTIONS: A CADD-Solis Pain Management System v3.0 with Programmed Intermittent Bolus Model 2110 was connected via a 3-way adapter to an epidural catheter and a digital pressure transducer. Pressures generated by delivery speeds of 100, 175, 300, and 400 mL/h of saline solution were tested with 4 epidural catheters (2 single orifice and 2 multiorifice). These runs were replicated on 5 pumps. Analysis of variance was used to compare the mean peak pressures of each delivery speed within each catheter group (single orifice and multiorifice). MAIN RESULTS: Thirty runs at each delivery speed were performed with each type of catheter for a total of 240 experimental runs. Peak pressure increased with increasing delivery speeds in both catheter groups (P<.001). Peak pressures were higher with the multiorifice catheter compared with the single orifice catheter at all delivery speeds (P<.001, for all). CONCLUSION: Using a pump designed for programmed intermittent infusion boluses, the delivery speed of saline solution through epidural catheters was directly related to the peak pressures. Future work should evaluate whether differences in the delivery speed of anesthetic solution into the epidural space correlate with differences in the duration and quality of analgesia during programmed intermittent epidural bolus delivery. PMID- 27687463 TI - Confirmation of laryngeal mask airway placement by ultrasound examination: a pilot study. AB - STUDY OBJECTIVE: We sought to validate ultrasound against other established methods of confirming laryngeal mask airway (LMA) placement. DESIGN: An observational study. SETTING: A university teaching hospital, operating department. PATIENTS: Fifty-eight patients undergoing general anesthesia using an LMA Supreme supraglottic airway device. INTERVENTIONS: The position of the LMA was assessed by ultrasound in 3 planes: the pharynx, the larynx, and along the cranial-caudal axis in the midline. The leakage test at 20 cm H2O and fiberoptic examination were also undertaken independently, with the latter being used to detect suboptimal placement (in which case, the LMA was reinserted). MEASUREMENTS: We scored the position of the LMA based on the location of the cuff and whether it had inflated correctly in each of the 3 planes. This score was converted to correspond with the leakage test grading system. We tested the strength of the correlation between the scores and the sensitivity and specificity for predicting reinsertion. MAIN RESULTS: Seven patients (12.1%) required LMA reinsertion, and ventilation was inadequate in a further 6 (10.3%). Three patients (5.2%) developed laryngospasm and inspiratory stridor after insertion resulting in inadequate ventilation, but none needed reinsertion as optimal placement was confirmed by fiberscope. Spearman coefficient of rank correlation between the leakage test and ultrasound examination was 0.713 (P< .0001). The kappa test and Bland-Altman analysis showed good agreement between the 2 scoring systems (weighted kappa = 0.605, standard error = 0.086). An ultrasound examination score equating to grade 3 in the leakage test predicted the need for reinsertion with a sensitivity and specificity of 85.7% and 94.1%, respectively. CONCLUSIONS: Ultrasound examination is a fast, noninvasive and reliable means of detecting LMA misplacement that agrees closely with the leakage test. Ultrasound is as effective as a fiberoptic examination to confirm LMA placement and indicate the need for reinsertion, but does not require ventilation to be interrupted. PMID- 27687464 TI - Effects of music on sedation depth and sedative use during pediatric dental procedures. AB - STUDY OBJECTIVE: The study aimed to investigate the effects of listening to music or providing sound isolation on the depth of sedation and need for sedatives in pediatric dental patients. DESIGN: Prospective, randomized, and controlled study. SETTING: Tertiary, university hospital. PATIENTS: In total, 180 pediatric patients, American Society of Anesthesiologists physical status I and II, who were scheduled for dental procedures of tooth extraction, filling, amputation, and root treatment. INTERVENTIONS: Patients were categorized into 3 groups: music, isolation, and control. During the procedures, the patients in the music group listened to Vivaldi's The Four Seasons violin concertos by sound-isolating headphones, whereas the patients in the isolation group wore the headphones but did not listen to music. All patients were sedated by 0.1 mg/kg midazolam and 1 mg/kg propofol. During the procedure, an additional 0.5 mg/kg propofol was administered as required. MEASUREMENTS AND MAIN RESULTS: Bispectral index was used for quantifying the depth of sedation, and total dosage of the propofol was used for sedative requirements. The patients' heart rates, oxygen saturations, and Observer's Assessment of Alertness and Sedation Scale and bispectral index scores, which were monitored during the operation, were similar among the groups. In terms of the amount of propofol used, the groups were similar. Prolonged postoperative recovery cases were found to be significantly frequent in the control group, according to the recovery duration measurements (P = .004). CONCLUSIONS: Listening to music or providing sound isolation during pediatric dental interventions did not alter the sedation level, amount of medication, and hemodynamic variables significantly. This result might be due to the deep sedation levels reached during the procedures. However, listening to music and providing sound isolation might have contributed in shortening the postoperative recovery duration of the patients. PMID- 27687465 TI - Chlorhexidine-related refractory anaphylactic shock: a case successfully resuscitated with extracorporeal membrane oxygenation. AB - IMPORTANCE: We report a patient with a life-threatening anaphylactic reaction to a chlorhexidine-coated central venous catheter, confirmed with a high serum level of chlorhexidine-specific IgE. To our knowledge, this is the first case successfully resuscitated using extracorporeal membrane oxygenation (ECMO). Great caution is required when using chlorhexidine and chlorhexidine-impregnated catheters, given that its widespread use has the potential to sensitize certain patients and may result in life-threatening anaphylaxis on subsequent exposure. OBSERVATIONS: A case report of a single patient with life-threatening anaphylactic shock to chlorhexidine, who was successfully resuscitated using ECMO. CONCLUSIONS: We have designed a flowchart for the diagnosis and management of severe anaphylaxis. This case report highlights the potential for chlorhexidine to be a source for the development of refractory anaphylactic shock. We suggest that ECMO may save the lives of patients with severe bronchospasm and refractory anaphylactic shock secondary to chlorhexidine. PMID- 27687466 TI - Assessing electronic interruptions experienced by an anesthesiology clinical director. AB - STUDY OBJECTIVE: The purpose of this study was to assess the workflow interruptions on an anesthesiology clinical director (CD). By assessing the interruptions on the CD, we hypothesize that these frequent interruptions would prohibit the CD from medical direction of residents or certified nurse anesthetists in operating rooms. DESIGN: Cellular phone data were obtained from Verizon Wireless statements over 10 months, August 2012 through May 2013. These data were from a single cellular phone carried by the anesthesia CD and subsequent overnight anesthesiologist 24 hours a day. The data obtained from the billing records included number of calls, date and time call occurred, number of minutes per call, and number of texts received. SETTING: These calls occurred in the operating room. PATIENTS: Not applicable. INTERVENTION: Not applicable. MEASUREMENTS: Phone calls, texts, and pager interruptions. MAIN RESULTS: A total of 19,924 calls and 19,803 texts were received by the CD. The phone calls minutes for this period were 31,236 minutes. A total of 15,831 (80%) of the calls occurred during this period (0600-1800). A total of 24 489 minutes (78%) of the total minutes occurred during this time. CONCLUSION: This study revealed that distracting events are frequent for an anesthesiology CD. The quantity of cellular phone interruptions, both calls and texts, by the anesthesiology CD was considered high. These calls occurred mainly during prime operating room time and utilization. As the CD is an integral part of the perioperative management team, they are expected to answer and return calls and texts promptly. Operating room efficiency and staff satisfaction decline if responses to these calls and texts are delayed. Although the nature of these distractions and interruptions can be viewed as having a positive or negative effect, many of these events are necessary to efficiently run the operating rooms. PMID- 27687467 TI - A temporal analysis of opioid use, patient satisfaction, and pain scores in colorectal surgery patients. AB - BACKGROUND: Recent health care policy changes promote objective measurements of patient satisfaction with care provided during hospitalization. Acute postsurgical pain is a significant medical problem and strongly impacts patient experience and patient satisfaction. Multimodal analgesic pathways are used for acute pain management, but opioid medications remain a mainstay of treatment. Opioid use is increasing in the outpatient setting, but opioid use trends in the inpatient postsurgical setting are not well known. We hypothesized that use of opioid medications has increased over time along with decrease in postoperative pain scores and increase in pain-related patient satisfaction. METHODS: In this single-center study, we studied the trends and correlation in the average daily pain scores, opioid consumption, and patient satisfaction scores as measured by pain-related patient satisfaction questions in the Hospital Consumer Assessment of Healthcare Providers and System survey. Pain scores and opioid use data were obtained from electronic health records, vital signs monitoring, and medication databases. Adult patients who had nonemergent colorectal surgeries between January 2009 and December 2012 were included. RESULTS: We found no significant trend in opioid use or pain-related patient satisfaction scores. There was an average annual increase of 0.3 (98.3% confidence interval, 0.2-0.4; P< .001) in average daily pain score from 2.8 +/- 1.5 to 3.8 +/- 1.5. The univariable associations between time-weighted pain score, average daily opioid dose, and pain-related patient satisfaction score were all highly significant. CONCLUSION: In this retrospective cohort study, opioid use and pain-related patient satisfaction scores were stable over time. Pain-related patient satisfaction scores were negatively associated with both pain score and opioid dose. The associations we report should not be considered evidence of a causal relationship.

AB - STUDY OBJECTIVE: Compare the effectiveness of nerve stimulator-guided pudendal nerve block (PNB) vs general anesthesia (GA) for anterior and posterior (AP) colporrhaphy in terms of pain relief and analgesic consumption within 24 and 48 hours postoperatively. DESIGN: Prospective randomized trial. PATIENTS: Fifty seven patients whose ages ranged between 20 and 53 years scheduled to undergo AP colporrhaphy due to the presence of cystorectocele. INTERVENTIONS: Patients were randomly assigned into 2 groups receiving either nerve stimulator-guided PNB (n = 28) or GA (n = 29). A total volume of 0.7 mL/kg of the local anesthetic mixture was injected at 4 sites. MAIN RESULTS: Both groups were similar with respect to age, weight, height, and surgery duration. There was a significant difference in average pain scores within the first and second postoperative days (P values = .005 and .004, respectively). Total analgesic consumption (ketoprofen and tramadol) was significantly lower in the PNB within the first (P values = .018 and .010) and second postoperative days (P values = .041 and .011), respectively. Return to normal daily activity was significantly (P< .0001) shorter in the PNB group compared with the GA group (3.6 days vs 12.2 days). A total of 71.4% of the patients in the PNB group were satisfied compared with 27.8% in the GA group (P< .0001). Surgeon satisfaction was significantly higher in the PNB group (82.1% vs 34.5%, P< .0001). CONCLUSION: This randomized controlled trial demonstrated that nerve stimulator-guided PNB could be used as an alternative to GA for AP repair of stages I and II prolapse because it is associated with less postoperative pain and analgesic consumption, in addition to shorter duration of recovery.

PMID- 27687471 TI - Impact of Hair Removal on Surgical Site Infection Rates: A Prospective Randomized Noninferiority Trial. AB - BACKGROUND: Despite substantial prevention efforts, surgical site infections (SSIs) remain the most common health care-associated infection. It is unclear whether the Centers for Disease Control and Prevention recommendation to leave hair intact preoperatively reduces SSIs. STUDY DESIGN: A single-center, prospective, randomized, clinical trial was conducted from October 2009 to February 2015 in a 325-bed multispecialty, tertiary care teaching hospital to test the noninferiority of clipping hair to no hair removal in the prevention of SSIs. A total of 4,908 adults scheduled for elective general surgical procedures were screened for study participation. Of these, 600 were approached but refused, and 2,630 were excluded. Patients were randomized 1:1 to either the clipped group (n = 834) or the not-clipped group (n = 844). The clipped group had hair at the surgical site removed using disposable electric clippers. Of the randomized patients, 1,543 (768 in the clipped group and 775 in the not-clipped group) completed follow-up. The primary endpoint was the proportion of patients who could be evaluated and who had no SSI, as defined by CDC criteria. RESULTS: Baseline demographic, clinical, and surgical characteristics were similar between groups. The overall rate of SSI in the per-protocol analysis was 6.12% (47 of 768) in the clipped group and 6.32% (49 of 775) in the not-clipped group (absolute risk difference -0.20%; 95% CI -2.61% to 2.21%), p = 0.037). Because the absolute risk difference confidence interval included the prespecified noninferiority margin of 2%, we were unable to definitively demonstrate noninferiority for clipping hair. CONCLUSIONS: Surgical site infection rates were similar whether hair was clipped or not in patients undergoing general surgical procedures.

However, limited studies have followed individuals pre- and post initiation of alcohol and marijuana use to help identify to what extent discrepancies in structural brain integrity are pre-existing or substance related. Adolescents (N=69) were followed from ages 13 (pre-initiation of substance use, baseline) to ages 19 (post-initiation, follow-up). Three subgroups were identified, participants that initiated alcohol use (ALC, n=23, >20 alcohol use episodes), those that initiated both alcohol and marijuana use (ALC+MJ, n=23, >50 marijuana use episodes) and individuals that did not initiate either substance regularly by follow-up (CON, n=23, <3 alcohol use episodes, no marijuana use episodes). All adolescents underwent neurocognitive testing, neuroimaging, and substance use and mental health interviews. Significant group by time interactions and main effects on cortical thickness estimates were identified for 18 cortical regions spanning the left and right hemisphere (ps<0.05). The vast majority of findings suggest a more substantial decrease, or within-subjects effect, in cortical thickness by follow-up for individuals who have not initiated regular substance use or alcohol use only by age 19; modest between-group differences were identified at baseline in several cortical regions (ALC and CON>ALC+MJ). Minimal neurocognitive differences were observed in this sample. Findings suggest pre-existing neural differences prior to marijuana use may contribute to initiation of use and observed neural outcomes. Marijuana use may also interfere with thinning trajectories that contribute to morphological differences in young adulthood that are often observed in cross-sectional studies of heavy marijuana users. PMID- 27687472 TI - A new multiple sex chromosome system X1X1X2X2/X1Y1X2Y2 in Siluriformes: cytogenetic characterization of Bunocephalus coracoideus (Aspredinidae). AB - We analyzed one Bunocephalus coracoideus population from the Negro River basin using cytogenetic techniques. The results showed a diploid number of 42 chromosomes in both sexes, with the karyotypic formula 4m + 14sm + 24a and fundamental number (FN) = 60 for females and the formula 5m + 14sm + 23a and FN = 61 for males, constituting an X1X1X2X2/X1Y1X2Y2 multiple sex chromosome system. The constitutive heterochromatin is distributed in the pericentromeric regions of most of the chromosomes, except for the sex chromosomes, of which the X1, X2, and Y1 chromosomes were euchromatic and the Y2 chromosome was partially heterochromatic. 18S rDNA mapping confirmed the presence of nucleolar organizer regions on the short arms of the fifth chromosomal pair for both sexes. The 5S rDNA is present in the terminal regions of the short arms on the 2nd, 10th, and 12th pairs and on the X2 chromosome of both sexes; however, we observed variations in the presence of these ribosomal cistrons on the Y1 chromosome, on which the cistrons are pericentromeric, and on the Y2 chromosome, on which these cistrons are present in the terminal portions of the short and long arms. Telomeric sequences are located in the terminal regions of all of the chromosomes, particularly conspicuous blocks on the 10th and 12th pairs and internal telomeric sequences in the centromeric regions of the 1st, 6th, and 9th pairs for both sexes. This work describes an new sex chromosomes system for the Siluriformes and increases our genetic knowledge of the Aspredinidae family. PMID- 27687473 TI - On the mechanism of ubiquinone mediated photocurrent generation by a reaction center based photocathode. AB - Upon photoexcitation, the reaction center (RC) pigment-proteins that facilitate natural photosynthesis achieve a metastable separation of electrical charge among the embedded cofactors. Because of the high quantum efficiency of this process, there is a growing interest in their incorporation into biohybrid materials for solar energy conversion, bioelectronics and biosensing. Multiple bioelectrochemical studies have shown that reaction centers from various photosynthetic organisms can be interfaced with diverse electrode materials for the generation of photocurrents, but many mechanistic aspects of native protein functionality in a non-native environment is unknown. In vivo, RC's catalyse ubiquinone-10 reduction, protonation and exchange with other lipid phase ubiquinone-10s via protein-controlled spatial orientation and protein rearrangement. In contrast, the mechanism of ubiquinone-0 reduction, used to facilitate fast RC turnover in an aqueous photoelectrochemical cell (PEC), may not proceed via the same pathway as the native cofactor. In this report we show truncation of the native isoprene tail results in larger RC turnover rates in a PEC despite the removal of the tail's purported role of ubiquinone headgroup orientation and binding. Through the use of reaction centers with single or double mutations, we also show the extent to which two-electron/two-proton ubiquinone chemistry that operates in vivo also underpins the ubiquinone-0 reduction by surface-adsorbed RCs in a PEC. This reveals that only the ubiquinone headgroup is critical to the fast turnover of the RC in a PEC and provides insight into design principles for the development of new biophotovoltaic cells and biosensors.

AB - The herbicide atrazine has been used worldwide with subsequent residual contamination of water and food, which may cause adverse effects on non-target organisms. Animal exposure to this herbicide may affect development, reproduction and energy metabolism. Here, the effects of atrazine regarding survival and redox metabolism were assessed in the fruit fly D. melanogaster exposed during embryonic and larval development. The embryos (newly fertilized eggs) were exposed to different atrazine concentrations (10MUM and 100MUM) in the diet until the adult fly emerged. Pupation and emergence rates, developmental time and sex ratio were determined as well as oxidative stress parameters and gene expression of the antioxidant defence system were evaluated in newly emerged male and female flies. Atrazine exposure reduced pupation and emergence rates in fruit flies without alterations to developmental time and sex ratio. Different redox imbalance patterns were observed between males and females exposed to atrazine. Atrazine caused an increase in oxidative damage, reactive oxygen species generation and antioxidant capacity and decreased thiol-containing molecules. Further, atrazine exposure altered the mRNA expression of antioxidant genes (keap1, sod, sod2, cat, irc, gss, gclm, gclc, trxt, trxr-1 and trxr-2). Reductions in fruit fly larval and pupal viability observed here are likely consequences of the oxidative stress induced by atrazine exposure. PMID- 27687476 TI - Consequences of the Convergence of Multiple Alternate Pathways on the Estrogen Receptor in the Treatment of Metastatic Breast Cancer. AB - Endocrine therapy is the usual first-line therapy for patients with hormone receptor-positive metastatic breast cancer. However, resistance to hormone therapies frequently occurs during the course of treatment. Growing understanding of the signal cascade of estrogen receptors and the signaling pathways that interact with estrogen receptors has revealed the complex role of these receptors in cell growth and proliferation, and on the mechanism in development of resistance. These insights have led to the development of targeted therapies that may prove to be effective options for the treatment of breast cancer and may overcome hormone therapy resistance. This article reviews current understanding of the cellular receptor signaling pathways that interact with estrogen receptors. It also reviews data from recent ongoing clinical trials that examine the effects of targeted therapies, which might interfere with estrogen receptor pathways and might reduce or reverse resistance to traditional, sequential, single-agent endocrine therapy. PMID- 27687475 TI - Structures of the colossal RyR1 calcium release channel. AB - Ryanodine receptors (RyRs) are intracellular cation channels that mediate the rapid and voluminous release of Ca2+ from the sarcoplasmic reticulum (SR) as required for excitation-contraction coupling in cardiac and skeletal muscle. Understanding of the architecture and gating of RyRs has advanced dramatically over the past two years, due to the publication of high resolution cryo-electron microscopy (cryoEM) reconstructions and associated atomic models of multiple functional states of the skeletal muscle receptor, RyR1. Here we review recent advances in our understanding of RyR architecture and gating, and highlight remaining gaps in understanding which we anticipate will soon be filled. PMID- 27687477 TI - Interactional synchrony and negative symptoms: An outcome study of body-oriented psychotherapy for schizophrenia. AB - OBJECTIVE: We sought to assess the efficacy of a manualized body-oriented psychotherapy (BPT) intervention for schizophrenia, by focusing on improvement of negative symptoms and on changes in interactional synchrony. We also explored aspects of a phenomenological theory of schizophrenia, which states that negative symptoms should be understood within an encompassing disturbance of subjectivity and intersubjectivity. METHOD: Sixteen persons with schizophrenia participated in 10 weeks of BPT. General psychiatric symptomatology and negative symptoms were assessed before and after therapy. Interactional synchrony was assessed via cross correlations of movements between patient and interviewer in interviews conducted before and after therapy. RESULTS: Psychiatric symptomatology and negative symptoms significantly improved with a medium effect size. We also demonstrated a significant increase in interactional synchrony with a strong effect size. Post hoc analyses showed a significant increase only with open-ended interviews conducted by the same interviewer. Furthermore, we explored the correlation between negative symptoms and interactional synchrony, finding a large inverse relationship. CONCLUSIONS: BPT for schizophrenia may effectively reduce patients' negative symptoms and psychiatric symptomatology. Moreover, it may yield some recovery of pre-reflective social relations. Further evidence of the specific relation between negative symptoms and interactional synchrony would support a phenomenologically informed holistic view of schizophrenia. PMID- 27687478 TI - Neem (Azadirachta indica): towards the ideal insecticide? AB - Pesticide resistance is going to change rapidly our antibiotics and insecticides arsenal. In this scenario, plant-derived natural products are considered valuable candidates to reverse this negative trend. Growing research attention is focused on neem (Azadirachta indica, Meliaceae), exploring the utility of its products as insecticides and antibiotics. In this review, we summarised the knowledge on neem oil and neem cake by-products in arthropod pest control, with special reference to mosquito vectors of public health importance. To the best of our knowledge, neem-borne products currently showed effective and eco-friendly features, including little non-target effects, multiple mechanisms of action, low cost, easy production in countries with limited industrial facilities. In particular, the potentiality of neem cake as ideal and affordable source of mosquitocidal compounds in anopheline and aedine control programmes is outlined. Overall, we propose the employ of neem-based products as an advantageous alternative to build newer and safer arthropod control tools. PMID- 27687479 TI - Rab3a and Rab10 are regulators of lysosome exocytosis and plasma membrane repair. AB - Disruption of the cell plasma membrane can occur due to mechanical damage, pore forming toxins, etc. Resealing or plasma membrane repair (PMR) is the emergency response required for cell survival. It is triggered by Ca2+ entering through the disruption, causing organelles such as lysosomes located underneath the plasma membrane to fuse rapidly with the adjacent plasma membrane. We have recently identified some of the molecular traffic machinery that is involved in this vital process. Specifically, we showed that 2 members of the Rab family of small GTPases, Rab3a and Rab10, are essential for lysosome exocytosis and PMR in cells challenged with a bacterial toxin, streptolysin-O (SLO). Additionally, we showed that Rab3a regulates PMR via the interaction with 2 effectors, synaptotagmin-like protein 4a (Slp4-a) and nonmuscle myosin heavy chain IIA (NMHC IIA), the latter being identified for the first time as a Rab3a effector. This tripartite complex is essential for the positioning of the peripheral lysosomes responsible for PMR. In cells lacking any of the components of this tripartite complex, lysosomes were concentrated in the perinuclear region and absent in the periphery culminating with PMR inhibition.

PMID- 27687482 TI - The IL-20 receptor axis in immune-mediated inflammatory arthritis: novel links between innate immune recognition and bone homeostasis. AB - The treatment of rheumatoid arthritis (RA) and spondyloarthritis (SpA) was transformed a little over a decade ago by the introduction of agents neutralizing the pro-inflammatory cytokine tumour necrosis factor (TNF)-alpha. Nevertheless, some patients do not achieve remission and the inhibition of the normal immune system with current drugs increases the risk of infection. The interleukin (IL) 20 receptor (IL-20R) axis is pivotal for tissue homeostasis. By contrast, this axis does not seem to directly activate cells of the immune system. Thus, modulation of the IL-20R axis might not result in increased risk of infection. The IL-20R axis consists of the three cytokines IL-19, IL-20, and IL-24 (termed the IL-20R cytokines) and their shared receptors. All three cytokines bind the receptor complex of IL-20R2/IL-20R1 whereas only IL-20 and IL-24 also bind the receptor complex of IL-20R2/IL-22R1. This short review describes how the IL-20R axis could be a novel link between innate immune recognition and bone homeostasis. The IL-20R cytokines are produced in response to both danger associated molecular patterns and immune complexes formed by RA-associated autoantibodies. This could be of importance because these mediators can thus be present even in situations without inflammation. IL-19 shows anti-inflammatory properties in arthritis through IL-20R1. IL-20 and IL-24 through IL-22R seem to participate in the recruitment of mononuclear cells to the synovial joint and to sites of bone erosion in particular. Our results indicate that dual inhibition of IL-20 and IL-24 or attenuation of the shared IL-22R subunit could have a beneficial effect on radiographic progression, especially in seropositive RA. PMID- 27687480 TI - Enzymatic activities of circulating plasma proteasomes in newly diagnosed multiple myeloma patients treated with carfilzomib, lenalidomide and dexamethasone. AB - The proteasome inhibitor carfilzomib is highly effective in the treatment of multiple myeloma. It irreversibly binds the chymotrypsin-like active site in the beta5 subunit of the 20S proteasome. Despite impressive response rates when carfilzomib is used in combination with immunomodulatory agents in newly diagnosed multiple myeloma patients; no biomarker exists to accurately predict response and clinical outcomes. We prospectively assessed the activity in peripheral blood of the chymotrypsin-like (CHYM), caspase-like (CASP) and trypsin like (TRYP) proteolytic sites in 45 newly diagnosed multiple myeloma patients treated with eight cycles of carfilzomib, lenalidomide and dexamethasone (CRd) (NCT01402284). Samples were collected per protocol and proteasome activity measured through a fluorogenic assay. Median CHYM levels after one dose of carfilzomib decreased by >70%. CHYM and CASP activity decreased throughout treatment reaching a minimum after eight cycles of treatment. Higher levels of proteasome activity associated with higher disease burden (r > 0.30; p < 0.05) and higher disease stage (0.10 < p <0.20). No association was found with the probability of achieving a complete response, minimal residual disease negativity or time to best response. Further studies evaluating proteasome activity in malignant plasma cells may help elucidate how proteasome activity can be used as a biomarker in multiple myeloma. PMID- 27687483 TI - Hand osteoarthritis: current knowledge and new ideas. AB - Hand osteoarthritis (OA) is a prevalent disease that can lead to substantial pain and physical disability. Currently, no disease-modifying drugs exist for the treatment of OA. Most OA research has been conducted on knee OA and we have limited knowledge about disease mechanisms in hand OA. During her research career, Ida K Haugen (IKH) has focused on the epidemiology of hand OA and imaging techniques. She has established a large international network, providing the opportunity to study the epidemiology of hand OA in large international OA cohorts. In the Framingham study, she found that symptomatic hand OA was present in 16% of women and 8% of men aged between 40 and 84 years. In her PhD thesis, IKH studied the reliability and validity of magnetic resonance imaging (MRI) in hand OA. In collaboration with OMERACT (Outcome Measures in Rheumatology), an MRI scoring system for hand OA was developed. MRI is more sensitive than radiographs for detecting structural abnormalities. Synovitis, as detected by both MRI and ultrasound, is associated with pain and predicts future disease progression. Hence, synovitis may represent a treatment target in hand OA. Her future research plans include the observational Nor-Hand study and a placebo-controlled randomized trial on methotrexate (MTX) in hand OA. The data collection of 300 patients in the Nor-Hand study is ongoing, and focuses on causes of pain and novel imaging techniques to assess inflammation in hand OA. In a future clinical trial, patients with moderate to severe long-lasting pain and inflammation will be treated with MTX and the effect on pain and inflammation will be explored. PMID- 27687484 TI - Optimizing biological treatments for rheumatoid arthritis. AB - The area of rheumatoid arthritis (RA) treatment has been revolutionized during the last decades with the development of biological therapies and their introduction into daily clinical practice contributing greatly to this dramatic change. However, several aspects of the use of these highly effective but expensive therapies remain far from optimal. To date, there is no clear evidence for the optimal sequence of biological agents, and the choice of a second- or third-line biologic is random. The effect of drug levels and the presence of neutralizing anti-drug antibodies remain unclear. In addition, the identification of prognostic factors of response, both clinical and histopathological, is crucial for a more individualized treatment approach.

PMID- 27687487 TI - Individualized follicle-stimulating hormone dosing and in vitro fertilization outcome in agonist downregulated cycles: a systematic review. AB - INTRODUCTION: This systematic review examines whether individualized gonadotropin dosing in in vitro fertilization (IVF) leads to better outcomes with respect to safety, costs, and live birth rates compared with standard dosing. MATERIAL AND METHODS: Electronic databases searched were PubMed, Embase, and Cochrane. The primary outcome was live birth rate. The secondary outcomes included pregnancy rate, costs, and safety. Papers were critically appraised by two reviewers. RESULTS: A total of 7022 articles were retrieved and assessed for eligibility, of which seven randomized controlled trials were selected. All studies used gonadotropin-releasing hormone agonist co-treatment. Clinical and methodological heterogeneity was present, so data could not be pooled for meta-analysis. Only one study, that mainly included women with a good prognosis, revealed an increased chance of ongoing pregnancy in the individualized dosing group compared with standard treatment. With respect to safety, individualized dosing might reduce the occurrence of hyper-response and ovarian hyperstimulation syndrome, without affecting the outcome of pregnancy. In predicted poor responders, higher than standard dosages do not reduce the incidence of poor response. A cost efficacy analysis was not performed in any of the studies included. CONCLUSION: It is currently not possible to conclude whether individualized dosing leads to higher pregnancy or live birth rates compared with standard dosing, because evidence from well-designed studies that are adequately powered for one of these outcomes is lacking. So, large well-designed studies that evaluate the impact of individualized dosing on live birth rates are needed to assess whether individualized dosing should become the standard in IVF practice.

PMID- 27687493 TI - The peak velocity derived from the Carminatti Test is related to physical match performance in young soccer players. AB - The aim of this study was to examine the relationship between the peak velocity derived from the Carminatti Test (T-CAR) (PVT-CAR) and physical match performance in young soccer players. Thirty-three youth soccer players were recruited from 2 non-professional clubs. Friendly matches and small-sided game were performed. Physical match demands were assessed using Global Positioning System (GPS) technology. On a separate occasion, the players were submitted to the T-CAR. Players were categorised into 3 groups based on their T-CAR performance: Low (PVT CAR <= P33), Intermediate (P33 > PVT-CAR < P66) and High (PVT-CAR >= P66). The PVT-CAR (15.5 +/- 0.7 km.h-1) was significantly related to high-intensity activities (HIA; r = 0.78, P < 0.001), high-intensity running (HIR; r = 0.66, P < 0.001), sprinting (r = 0.62, P < 0.001) and total distance (TD) covered (r = 0.47, P < 0.01) during friendly matches. The PVT-CAR was strongly correlated with the amount of HIA (r = 0.81, P < 0.001), HIR (r = 0.85, P < 0.001) and TD covered (r = 0.81, P < 0.001) during small-sided game. No significant correlation was observed between the PVT-CAR and distance of sprinting (r = 0.49, P = 0.067) during small-side game. Furthermore, players in the High group covered significantly more TD (10%) and did more HIA (42%), sprinting (31%) and HIR (25%) during friendly matches compared to the players classified as having Low performance on the T-CAR. These differences still remained after adjusting for chronological age (CA), maturity and body size. In conclusion, the current study gives empirical support to the ecological and construct validity of this novel field test (T-CAR) as an indicator of match-related physical performance in young soccer players during pubertal years. PMID- 27687492 TI - Single-cell analysis reveals IGF-1 potentiation of inhibition of the TGF beta/Smad pathway of fibrosis in human keratocytes in vitro. AB - Corneal wound healing is often affected by TGF-beta-mediated fibrosis and scar formation. Guided fibrosis with IGF-1 and antifibrotic substances might maintain corneal transparency. Primary human corneal keratocytes under serum-free conditions were used as a model of corneal stromal wounding, with markers of corneal fibrosis and opacity studied under TGF-beta2 stimulation. Single-cell imaging flow cytometry was used to determine nuclearization of Smad3, and intracellular fluorescence intensity of Smad7 and the corneal crystallin aldehyde dehydrogenase 3A1. Extracellular matrix proteoglycans keratocan and biglycan were quantified using ELISAs. On the TGF-beta2 background, the keratocytes were treated with IGF-1, and suberoylanilidehydroxamic acid (SAHA) or halofuginone +/- IGF-1. IGF-1 alone decreased Smad3 nuclearization and increased aldehyde dehydrogenase 3A1 expression, with favorable extracellular matrix proteoglycan composition. SAHA induced higher Smad7 levels and inhibited translocation of Smad3 to the nucleus, also when combined with IGF-1. Immunofluorescence showed that myofibroblast transdifferentiation is attenuated and appearance of fibroblasts is favored by IGF-1 alone and in combination with the antifibrotic substances. The TGF-beta/Smad pathway of fibrosis and opacity was inhibited by IGF-1, and further with SAHA in particular, and with halofuginone. IGF-1 is thus a valid aid to antifibrotic treatment, with potential for effective and transparent corneal wound healing. PMID- 27687494 TI - The endocrine influence on the bone microenvironment in early breast cancer. AB - Multiple factors influence the survival of disseminated breast tumour cells (DTCs) in bone. Whereas gene signature studies have identified genes that predict a propensity of tumours to metastasise to bone, the bone environment is key in determining the fate of these tumour cells. Breast cancer cells locate to specific niches within the bone that support their survival, regulated by host factors within the bone microenvironment including bone cells, cells of the bone micro vasculature, immune cells and the extracellular matrix. Reproductive endocrine hormones that affect bone and clinical studies across the menopausal transition have provided comprehensive understanding of the changes in the bone microenvironment during this time. Menopause is characterized by a decrease in ovarian oestradiol and inhibins, with an increase in pituitary follicle stimulating hormone and this review will focus on the role of these three hormones in determining the fate of DTCs in bone. Both in vivo and clinical data suggest that premenopausal bone is a conducive environment for growth of breast cancer cells in bone. Adjuvant cancer treatment aims to reduce the risk of tumour recurrence by affecting DTCs. Drugs targeting the bone resorbing osteoclasts, such as bisphosphonates, have therefore been evaluated in this setting. Both preclinical and adjuvant clinical studies have shown that bisphosphonates' ability to decrease tumour growth in bone is influenced by the levels of endocrine hormones, with enhanced effects in a postmenopausal bone microenvironment. The challenge is to understand the molecular mechanisms behind this phenomenon and to evaluate if alternative adjuvant bone-targeted therapies may be effective in premenopausal women. PMID- 27687495 TI - Frequency-time coherence for all-optical sampling without optical pulse source. AB - Sampling is the first step to convert an analogue optical signal into a digital electrical signal. The latter can be further processed and analysed by well-known electrical signal processing methods. Optical pulse sources like mode-locked lasers are commonly incorporated for all-optical sampling, but have several drawbacks. A novel approach for a simple all-optical sampling is to utilise the frequency-time coherence of each signal. The method is based on only using two coupled modulators driven with an electrical sine wave. Since no optical source is required, a simple integration in appropriate platforms, such as Silicon Photonics might be possible. The presented method grants all-optical sampling with electrically tunable bandwidth, repetition rate and time shift.

AB - INTRODUCTION: Anti TNF-alpha agents have become a significant advance in the management of ulcerative colitis, proving to induce, with rapid onset, clinical and endoscopic remission. However, there is still a considerable unmet medical need in ulcerative colitis. Areas covered: The aim of this review was to summarize the patterns of use and the effectiveness of anti TNF-alpha in ulcerative colitis, highlighting their current position in treatment algorithms. Moreover, we set out a five-year view hypothesizing different treatment strategies. Expert commentary: The rapid onset of action and the effectiveness in inducing mucosal healing are the most important pros of anti TNF-alpha, supporting present and future use. Conversely, the relevant risk of loss of response and the safety profile have raised several concerns. In the future, the advent of different molecular targeting therapies can improve the management of UC patients, evolving to individually tailored strategies. PMID- 27687497 TI - Antagonistic roles of Drosophila Tctp and Brahma in chromatin remodelling and stabilizing repeated sequences. AB - Genome stability is essential for all organisms. Translationally controlled tumour protein (TCTP) is a conserved protein associated with cancers. TCTP is involved in multiple intracellular functions, but its role in transcription and genome stability is poorly understood. Here, we demonstrate new functions of Drosophila TCTP (Tctp) in transcription and the stability of repeated sequences (rDNA and pericentromeric heterochromatin). Tctp binds Brahma (Brm) chromatin remodeler to negatively modulate its activity. Tctp mutants show abnormally high levels of transcription in a large set of genes and transposons. These defects are ameliorated by brm mutations. Furthermore, Tctp promotes the stability of repeated sequences by opposing the Brm function. Additional regulation of pericentromeric heterochromatin by Tctp is mediated by su(var)3-9 transcriptional regulation. Altogether, Tctp regulates transcription and the stability of repeated sequences by antagonizing excess Brm activity. This study provides insights into broader nuclear TCTP functions for the maintenance of genome stability. PMID- 27687498 TI - A general solution for opening double-stranded DNA for isothermal amplification. AB - Nucleic acid amplification is the core technology of molecular biology and genetic engineering. Various isothermal amplification techniques have been developed as alternatives to polymerase chain reaction (PCR). However, most of these methods can only detect single stranded nucleic acid. Herein, we put forward a simple solution for opening double-stranded DNA for isothermal detection methods. The strategy employs recombination protein from E. coli (RecA) to form nucleoprotein complex with single-stranded DNA, which could scan double stranded template for homologous sites. Then, the nucleoprotein can invade the double-stranded template to form heteroduplex in the presence of ATP, resulting in the strand exchange. The ATP regeneration system could be eliminated by using high concentration of ATP, and the 3'-OH terminal of the invasion strand can be recognized by other DNA modifying enzymes such as DNA polymerase or DNA ligase. Moreover, dATP was found to be a better cofactor for RecA, which make the system more compatible to DNA polymerase. The method described here is a general solution to open dsDNA, serving as a platform to develop more isothermal nucleic acids detection methods for real DNA samples based on it.

AB - Peters Plus syndrome (PPS), a congenital disorder of glycosylation, results from recessive mutations affecting the glucosyltransferase B3GLCT, leading to congenital corneal opacity and diverse extra-ocular manifestations. Together with the fucosyltransferase POFUT2, B3GLCT adds Glucosebeta1-3Fucose disaccharide to a consensus sequence in thrombospondin type 1 repeats (TSRs) of several proteins. Which of these target proteins is functionally compromised in PPS is unknown. We report here that haploinsufficiency of murine Adamts9, encoding a secreted metalloproteinase with 15 TSRs, leads to congenital corneal opacity and Peters anomaly (persistent lens-cornea adhesion), which is a hallmark of PPS. Mass spectrometry of recombinant ADAMTS9 showed that 9 of 12 TSRs with the O fucosylation consensus sequence carried the Glucosebeta1-3Fucose disaccharide and B3GLCT knockdown reduced ADAMTS9 secretion in HEK293F cells. Together, the genetic and biochemical findings imply a dosage-dependent role for ADAMTS9 in ocular morphogenesis. Reduced secretion of ADAMTS9 in the absence of B3GLCT is proposed as a mechanism of Peters anomaly in PPS. The functional link between ADAMTS9 and B3GLCT established here also provides credence to their recently reported association with age-related macular degeneration.

AB - BACKGROUND: Facility-based births have been promoted as the main strategy to reduce maternal and neonatal death risks at global scale. To improve birth outcomes, it is critical that health facilities provide quality care. Using a framework to assess quality of care, this paper examines health workers' perceptions about access to facility birth; the effectiveness of the care provided and obstacles to quality birth care in a rural area of Burkina Faso. METHODS: A qualitative study was conducted in 2011 in the Banfora Region, Burkina Faso. Participant observations were carried out in four different health centres for a period of three months; more than 30 deliveries were observed. In-depth interviews were conducted with 12 frontline health workers providing birth care and with two staff of the local health district management team. Interview transcripts and field notes were analysed thematically. RESULTS: Health workers in this rural area of Burkina Faso provided birth care in a context of limited financial resources, insufficient personnel and poorly equipped facilities; the quality of the birth care provided was severely compromised. Health workers tended to place the responsibility for poor quality of care on infrastructural limitations and patient behaviour, while our observational data also identified missed opportunities that would not demand additional resources throughout the process of care like early initiation of breastfeeding and skin-to-skin contact after birth. Health workers felt disempowered, having limited abilities to prevent and treat birth complications, and resorted to alternative and potentially harmful strategies. CONCLUSIONS: We found poor quality of care at birth, missed opportunities, and health worker disempowerment in rural health facilities of Banfora, Burkina Faso. There is an urgent need to provide health workers with the necessary tools to prevent and handle birth complications, and to ensure that existing low cost life-saving interventions in maternal and new born health are appropriately used and integrated into the daily routines in maternity wards at all levels.

AB - Maximizing the conversion of biogenic carbon feedstocks into chemicals and fuels is essential for fermentation processes as feedstock costs and processing is commonly the greatest operating expense. Unfortunately, for most fermentations, over one-third of sugar carbon is lost to CO2 due to the decarboxylation of pyruvate to acetyl-CoA and limitations in the reducing power of the bio feedstock. Here we show that anaerobic, non-photosynthetic mixotrophy, defined as the concurrent utilization of organic (for example, sugars) and inorganic (for example, CO2) substrates in a single organism, can overcome these constraints to increase product yields and reduce overall CO2 emissions. As a proof-of-concept, Clostridium ljungdahlii was engineered to produce acetone and achieved a mass yield 138% of the previous theoretical maximum using a high cell density continuous fermentation process. In addition, when enough reductant (that is, H2) is provided, the fermentation emits no CO2. Finally, we show that mixotrophy is a general trait among acetogens. PMID- 27687502 TI - Can CuO nanoparticles lead to epigenetic regulation of antioxidant enzyme system? AB - Copper has been used from ancient time in various applications. Scientists have exploited its means of exposure and consequences to living organisms. The peculiar property of nanomaterials that is a high surface to volume ratio has increased the range of application in products. Copper oxide nanoparticles (CuO NPs) are widely used in industrial applications such as semiconductor devices, gas sensor, batteries, solar energy converter, microelectronics, heat transfer fluids and consumer products. In contrast, acute toxicity of CuO NPs has also been reported. Subsequently, human and environmental health may be at a high risk. Their frequent use can also contaminate ecosystems. Therefore, the toxicity of CuO NPs needs to be thoroughly understood. In this review, we have tried to discuss the recent facts and mechanism that have been explored for CuO NPs induced toxicity at a cellular, in vivo and ecotoxicological level. Accordingly, the main cause for induction of toxicity by CuO NPs is the generation of reactive oxygen species (ROS) followed by the mitochondrial destruction that leads to apoptosis via the intrinsic pathway or under the condition such as hypoxia cell on exposure to CuO NPs may commit to necrosis. Moreover, CuO NPs also result in activation of MAPK pathways, ERKs and JNK/SAPK thus play an important role in the activation of AP-1. Furthermore, CuO NPs also leads to up-regulation of p53 and caspase three genes. Therefore, careful measures are required to explore omic technology to understand the molecular mechanism of the deleterious effects caused by CuO NPs. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - Although being an utterly frequent, non-mortal, yet distressing disease, and despite good knowledge of the pathogenesis and the availability of specific and safe treatment, vulvovaginal Candida (VVC) infection remains one of the most enigmatic problems for both physicians and patients. Good treatment requires a proper diagnosis. Too many caregivers (and patients treating themselves) react too simple-minded on the symptoms of VVC and treat VVC where they see it on the vulva. In this opinion paper, we plea for a thorough examination of women with VVC, especially in those women who suffer from recurrent disease since a long time, sometimes decades, which necessitates intensive examination of the vaginal flora, as this is invariably the reservoir for relapses and recurrent vulvitis. Examination of such complicated cases requires experienced clinical judgement, expertise bedside phase contrast microscopy of fresh vaginal fluid, classical cultures on Sabouroud medium and, if still unresolved, repetitive cultures taken by the patient herself at moments of symptoms, and/or nuclear acid amplification techniques to detect Candida genes in the vaginal fluid. Even if only vulvitis is evident, thorough expert examination of vaginal fluid is obligatory to diagnose VVC.

AB - A previous study has demonstrated that Ganshuang granule (GSG) plays an anti fibrotic role partially by deactivation of hepatic stellate cells (HSCs). In HSCs activation, mammalian target of rapamycin (mTOR)-autophagy plays an important role. We attempted to investigate the role of mTOR-autophagy in anti-fibrotic effect of GSG. The cirrhotic mouse model was prepared to demonstrate the anti fibrosis effect of GSG. High performance liquid chromatography (HPLC) analyses were used to identify the active component of GSG. The primary mouse HSCs were isolated and naringin was added into activated HSCs to observe its anti-fibrotic effect. 3-methyladenine (3-MA) and Insulin-like growth factor-1 (IGF-1) was added, respectively, into fully activated HSCs to explore the role of autophagy and mTOR. GSG played an anti-fibrotic role through deactivation of HSCs in cirrhotic mouse model. The concentration of naringin was highest in GSG by HPLC analyses and naringin markedly suppressed HSCs activation in vitro, which suggested that naringin was the main active component of GSG. The deactivation of HSCs caused by naringin was not because of the autophagic activation but mTOR inhibition, which was supported by the following evidence: first, naringin induced autophagic activation, but when autophagy was blocked by 3-MA, deactivation of HSCs was not attenuated or reversed. Second, naringin inhibited mTOR pathway, meanwhile when mTOR was activated by IGF-1, deactivation of HSCs was reversed. In conclusion, we have demonstrated naringin in GSG suppressed activation of HSCs for anti-fibrosis effect by inhibition of mTOR, indicating a potential therapeutic application for liver cirrhosis.

AB - Extracts of different parts (heads, bracts and stems) of Cynara cardunculus L. (cardoon) and Cynara scolymus L. (globe artichoke), obtained by two different extraction techniques (Ultrasound-Assisted Extraction (UAE) and classical extraction (CE)) were examined and compared for their total phenolic content (TPC) and their antioxidant activity. Moreover, infusions of the plant's parts were also analysed and compared to aforementioned samples. Results showed that cardoon's heads extract (obtained by Ultrasound-Assisted Extraction) displayed the highest TPC values (1.57 mg Gallic Acid Equivalents (GAE) g-1 fresh weight (fw)), the highest DPPH* scavenging activity (IC50; 0.91 mg ml-1) and the highest ABTS*+ radical scavenging capacity (2.08 mg Trolox Equivalents (TE) g-1 fw) compared to infusions and other extracts studied. Moreover, Ultrasound-Assisted Extraction technique proved to be more appropriate and effective for the extraction of antiradical and phenolic compounds. PMID- 27687507 TI - Oceanography promotes self-recruitment in a planktonic larval disperser. AB - The application of high-resolution genetic data has revealed that oceanographic connectivity in marine species with planktonic larvae can be surprisingly limited, even in the absence of major barriers to dispersal. Australia's southern coast represents a particularly interesting system for studying planktonic larval dispersal, as the hydrodynamic regime of the wide continental shelf has potential to facilitate onshore retention of larvae. We used a seascape genetics approach (the joint analysis of genetic data and oceanographic connectivity simulations) to assess population genetic structure and self-recruitment in a broadcast spawning marine gastropod that exists as a single meta-population throughout its temperate Australian range. Levels of self-recruitment were surprisingly high, and oceanographic connectivity simulations indicated that this was a result of low-velocity nearshore currents promoting the retention of planktonic larvae in the vicinity of natal sites. Even though the model applied here is comparatively simple and assumes that the dispersal of planktonic larvae is passive, we find that oceanography alone is sufficient to explain the high levels of genetic structure and self-recruitment. Our study contributes to growing evidence that sophisticated larval behaviour is not a prerequisite for larval retention in the nearshore region in planktonic-developing species.

AB - OBJECTIVE: There are currently no local data on the sperm retrieval and pregnancy rates in in-vitro fertilisation and testicular sperm extraction cycles, especially with regard to the presence of genetic abnormalities. This study aimed to determine the sperm retrieval and pregnancy rates in infertile couples who underwent in-vitro fertilisation and testicular sperm extraction for non obstructive azoospermia. METHODS: This retrospective case series was conducted at a tertiary assisted reproduction unit in Hong Kong. Men with non-obstructive azoospermia who underwent in-vitro fertilisation and testicular sperm extraction between January 2001 and December 2013 were included. The main outcome measures were sperm retrieval and pregnancy rates. RESULTS: During the study period, 89 men with non-obstructive azoospermia underwent in-vitro fertilisation and testicular sperm extraction. Sperm was successfully retrieved in 40 (44.9%) men. There was no statistically significant difference in the sperm retrieval rate of those with karyotypic abnormalities (2/5, 40.0% vs 28/61, 45.9%; P=1.000) and AZFc microdeletion (3/6, 50.0% vs 28/61, 45.9%; P=1.000) compared with those without. Sperms were successfully retrieved in patients who had mosaic Klinefelter syndrome (2/3, 66.7%) but not in the patient with non-mosaic Klinefelter syndrome. No sperms were found in men with AZFa or AZFb microdeletions. Pregnancy test was positive in 15 (16.9%) patients and the clinical pregnancy rate was 13.5% (12/89) per cycle. The clinical pregnancy rate per transfer was 34.3% (12/35). CONCLUSIONS: The sperm retrieval rate and clinical pregnancy rate per initiated cycle in men undergoing in-vitro fertilisation and testicular sperm extraction in our unit were 44.9% and 13.5%, respectively. No sperms could be retrieved in the presence of AZFa and AZFb microdeletions, but karyotype and AZFc microdeletion abnormalities otherwise did not predict the success of sperm retrieval in couples undergoing in-vitro fertilisation and testicular sperm extraction. Genetic tests are important prior to testicular sperm extraction for patient selection and genetic counselling.

AB - INTRODUCTION: The negative impact of paediatric cancer on parents is well known and is even greater when intensive treatments are used. This study aimed to describe how couples whose child has received a transplant for the treatment of leukaemia view conjugal resilience and to evaluate the role of we-ness as a precursor of conjugal adjustment. METHODS: Four parental couples were interviewed. Interviews were analysed in two ways: inductive thematic analysis and rating of verbal content with the We-ness Coding Scale. RESULTS: Participants report that conjugal resilience involves the identification of the couple as a team and cohesion in the couple. Being a team generates certain collaborative interactions that lead to conjugal resilience. A sense of we-ness in parents is associated with fluctuation in the frequency of themes. DISCUSSION: Participants' vision of conjugal resilience introduced novel themes. The sense of we-ness facilitates cohesion and the process of conjugal resilience.

AB - BACKGROUND: Helicobacter pylori (HP) infection induces methylation silencing of specific genes in gastric epithelium. Various stimuli activate the nonselective cation channel TRPV4, which is expressed in gastric epithelium where it detects mechanical stimuli and promotes ATP release. As CpG islands in TRPV4 are methylated in HP-infected gastric epithelium, we evaluated HP infection-dependent changes in TRPV4 expression in gastric epithelium. MATERIALS AND METHODS: Human gastric biopsy samples, a human gastric cancer cell line (AGS), and a normal gastric epithelial cell line (GES-1) were used to detect TRPV4 mRNA and protein expression by RT-PCR and Western blotting, respectively. Ca2+ imaging was used to evaluate TRPV4 ion channel activity. TRPV4 methylation status was assessed by methylation-specific PCR (MSP). ATP release was measured by a luciferin luciferase assay. RESULTS: TRPV4 mRNA and protein were detected in human gastric biopsy samples and in GES-1 cells. MSP and demethylation assays showed TRPV4 methylation silencing in AGS cells. HP coculture directly induced methylation silencing of TRPV4 in GES-1 cells. In human samples, HP infection was associated with TRPV4 methylation silencing that recovered after HP eradication in a time dependent manner. CONCLUSION: HP infection-dependent DNA methylation suppressed TRPV4 expression in human gastric epithelia, suggesting that TRPV4 methylation may be involved in HP-associated dyspepsia. PMID- 27687511 TI - Genetic diversity and population structure of Hyporhamphus sajori (Beloniformes: Hemiramphidae) inferred from mtDNA control region and msDNA markers. AB - This paper presents preliminary data on the genetic diversity and population structure of Hyporhamphus sajori by analysing a 510 bp sequence in the mitochondrial DNA (mtDNA) control region and eight polymorphic microsatellite DNA loci. The H. sajori individuals from different locations were indistinguishable from one another based on mtDNA variation, as demonstrated with a neighbour joining tree and minimum spanning network analysis. Low level of genetic diversity and the absence of population structure in H. sajori from the north west Pacific Ocean, combined with negative indices for neutral evolution in these populations, suggest that H. sajori underwent a population expansion after a recent bottleneck. The Structure analysis, discriminant analysis of principal components (DAPC) and the pair-wise PhiST values after Bonferroni correction using eight microsatellite loci provided no clear inference on the genetic differentiation and thus no evidence of population structure of H. sajori. The genetic connectivity among locations might be due to fairly high gene flow via transport of eggs and larvae by the Kuroshio and Tsushima warm current. This study revealed low levels of genetic diversity and suggested high level of contemporary gene flow among populations of H. sajori in the East (Japan) Sea and the Pacific Ocean.

AB - Cadmium (Cd) is one of the well-known highly toxic environmental and industrial pollutants. Cd first accumulates in the nucleus and later interacts with zinc finger proteins of antiapoptotic genes and inhibit the binding of transcriptional factors and transcription. However, the role of Cd in oxidative stress and apoptosis is less understood. Hence, the present study was undertaken to unveil the mechanism of action. A549 cells were treated with or without Cd and cell viability was measured by MTT assay. Treatment of cells with Cd shows reduced viability in a dose-dependent manner with IC50 of 45 MUM concentration. Cd significantly induces the reactive oxygen species (ROS), lipid peroxidation followed by membrane damage with the leakage of lactate dehydrogenase (LDH). Cells with continuous exposure of Cd deplete the antioxidant super oxide dismutase (SOD) and glutathione peroxidase (GSH-Px) enzymes. Further, analysis of the expression of genes involved in apoptosis show that both the extrinsic and intrinsic apoptotic pathways were involved. Death receptor marker tumor necrosis factor-alpha (TNF-alpha), executor caspase-8 and pro-apoptotic gene (Bax) were induced, while antiapoptotic gene (Bcl-2) was decreased in Cd-treated cells. Fluorescence-activated cell sorting (FACS) analysis further confirms the induction of apoptosis in Cd-treated A549 cells. PMID- 27687514 TI - Anatomic Patterns of Renal Arterial Sympathetic Innervation: New Aspects for Renal Denervation. AB - AIMS: Initial studies of catheter-based renal arterial sympathetic denervation to lower blood pressure in resistant hypertensive patients renewed interest in the sympathetic nervous system's role in the pathogenesis of hypertension. However, the SYMPLICITY HTN-3 study failed to meet its prespecified blood pressure lowering efficacy endpoint. To date, only a limited number of studies have described the microanatomy of renal nerves, of which, only two involve humans. METHODS AND RESULTS: Renal arteries were harvested from 15 cadavers from the Klinikum Osnabruck and Schuchtermann Klinik, Bad Rothenfelde. Each artery was divided longitudinally in equal thirds (proximal, middle, and distal), with each section then divided into equal superior, inferior, anterior, and posterior quadrants, which were then stained. Segments containing no renal nerves were given a score value = 0, 1-2 nerves with diameter <300 um a score = 1; 3-4 nerves or nerve diameter 300-599 um a score = 2, and >4 nerves or nerve diameter >=600 um a score = 3. A total of 22 renal arteries (9 right-sided, 13 left-sided) were suitable for examination. Overall, 691 sections of 5 mm thickness were prepared. Right renal arteries had significantly higher mean innervation grade (1.56 +/- 0.85) compared to left renal arteries (1.09 +/- 0.87) (P < 0.001). Medial (1.30 +/- 0.59) and distal (1.39 +/- 0.62) innervation was higher than the proximal (1.17 +/- 0.55) segments (p < 0.001). When divided in quadrants, the anterior (1.52 +/- 0.96) and superior (1.71 +/- 0.89) segments were more innervated compared to posterior (0.96 +/- 0.72) and inferior (0.90 +/- 0.68) segments (P < 0.001). CONCLUSIONS: That the right renal artery has significantly higher innervation scores than the left. The anterior and superior quadrants of the renal arteries scored higher in innervation than the posterior and inferior quadrants did. The distal third of the renal arteries are more innervated than the more proximal segments. These findings warrant further evaluation of the spatial innervation patterns of the renal artery in order to understand how it may enhance catheter-based renal arterial denervation procedural strategy and outcomes. CONDENSED ABSTRACT: The SYMPLICITY HTN-3 study dealt a blow to the idea of the catheter-based renal arterial sympathetic denervation. We investigated the location and patterns of periarterial renal nerves in cadaveric human renal arteries. To quantify the density of the renal nerves we created a novel innervation score. On average the right renal arteries were significantly more densely innervated than the left renal arteries, the anterior and superior segments were significantly more innervated compared to the posterior and inferior segments, absolute innervation scores in the proximal third of the left or right renal arteries were always lower when compared to distal segments. These findings may enhance catheter-based renal arterial denervation procedural strategy and outcomes. PMID- 27687515 TI - Psychological distress and coping in nasopharyngeal cancer: an explorative study in Western Europe. AB - Nasopharyngeal carcinoma (NPC) is the head and neck cancer with the greatest impact on patients' quality of life. The aim of this explorative study is to investigate the psychological distress, coping strategies and quality of life of NPC patients in the post-treatment observation period. Twenty-one patients disease-free for at least two years were assessed with a medical and a psycho oncological evaluation. Clinically relevant depressive symptoms (CRD) were present in 23.8% of patients and 33.3% reported clinically relevant anxiety symptoms (CRA). Patients with CRD and CRA showed a significantly higher score in the use of hopelessness/helplessness and anxious preoccupation coping strategies and a worse quality of life. Even in the post-treatment period, about a quarter of patients showed CRD and CRA. Results showed that patients with high anxiety or depressive symptoms seem to use dysfunctional coping strategies, such as hopelessness and anxious preoccupation, more than patients with lower levels of anxiety and depression. The use of these styles of coping thus seems to be associated to a higher presence of CRA or CRD symptomatology and to a worse quality of life. PMID- 27687516 TI - Productivity, Rank, and Returns in Polygamy. AB - This study sheds light on the development of family structures in a polygamous context with a particular emphasis on wife order, and offers an explanation for the association between outcomes of children and the status of their mothers among wives based on observable maternal characteristics. In a simple framework, I propose that selection into rank among wives with respect to female productivity takes place: highly productive women are more strongly demanded in the marriage market than less productive women, giving them a higher chance of becoming first wives. Furthermore, productivity is positively associated with a wife's bargained share of family income to be spent on consumption and investment for herself and her offspring because of greater contributions to family income and larger outside options. The findings are empirically supported by a positive relationship between indicators of female productivity and women's levels of seniority among wives, and by a concise replication of existing evidence relating wife order to children's educational outcomes in household survey data from rural Ethiopia. PMID- 27687517 TI - Number of evaluated lymph nodes and positive lymph nodes, lymph node ratio, and log odds evaluation in early-stage pancreatic ductal adenocarcinoma: numerology or valid indicators of patient outcome? AB - BACKGROUND: We evaluated the prognostic significance and universal validity of the total number of evaluated lymph nodes (ELN), number of positive lymph nodes (PLN), lymph node ratio (LNR), and log odds of positive lymph nodes (LODDS) in a relatively large and homogenous cohort of surgically treated pancreatic ductal adenocarcinoma (PDAC) patients. METHODS: Prospectively accrued data were retrospectively analyzed for 282 PDAC patients who had pancreaticoduodenectomy (PD) at our institution. Long-term survival was analyzed according to the ELN, PLN, LNR, and LODDS. RESULTS: Of these patients, 168 patients (59.5 %) had LN metastasis (N1). Mean ELN and PLN were 13.5 and 1.6, respectively. LN positivity correlated with a greater number of evaluated lymph nodes; positive lymph nodes were identified in 61.4 % of the patients with ELN >= 13 compared with 44.9 % of the patients with ELN < 13 (p = 0.014). Median overall survival (OS) and 5-year OS rate were higher in N0 than in N1 patients, 22.4 vs. 18.7 months and 35 vs. 11 %, respectively (p = 0.008). Mean LNR was 0.12; 91 patients (54.1 %) had LNR < 0.3. Among the N1 patients, median OS was comparable in those with LNR >= 0.3 vs. LNR < 0.3 (16.7 vs. 14.1 months, p = 0.950). Neither LODDS nor various ELN and PLN cutoff values provided more discriminative information within the group of N1 patients. CONCLUSIONS: Our data confirms that lymph node positivity strongly reflects PDAC biology and thus patient outcome. While a higher number of evaluated lymph nodes may provide a more accurate nodal staging, it does not have any prognostic value among N1 patients. Similarly, PLN, LNR, and LODDS had limited prognostic relevance. PMID- 27687518 TI - Quantification of gamma-aminobutyric acid (GABA) in 1 H MRS volumes composed heterogeneously of grey and white matter. AB - The quantification of gamma-aminobutyric acid (GABA) concentration using localised MRS suffers from partial volume effects related to differences in the intrinsic concentration of GABA in grey (GM) and white (WM) matter. These differences can be represented as a ratio between intrinsic GABA in GM and WM: rM . Individual differences in GM tissue volume can therefore potentially drive apparent concentration differences. Here, a quantification method that corrects for these effects is formulated and empirically validated. Quantification using tissue water as an internal concentration reference has been described previously. Partial volume effects attributed to rM can be accounted for by incorporating into this established method an additional multiplicative correction factor based on measured or literature values of rM weighted by the proportion of GM and WM within tissue-segmented MRS volumes. Simulations were performed to test the sensitivity of this correction using different assumptions of rM taken from previous studies. The tissue correction method was then validated by applying it to an independent dataset of in vivo GABA measurements using an empirically measured value of rM . It was shown that incorrect assumptions of rM can lead to overcorrection and inflation of GABA concentration measurements quantified in volumes composed predominantly of WM. For the independent dataset, GABA concentration was linearly related to GM tissue volume when only the water signal was corrected for partial volume effects. Performing a full correction that additionally accounts for partial volume effects ascribed to rM successfully removed this dependence. With an appropriate assumption of the ratio of intrinsic GABA concentration in GM and WM, GABA measurements can be corrected for partial volume effects, potentially leading to a reduction in between-participant variance, increased power in statistical tests and better discriminability of true effects.

AB - Ancient grain varieties have been shown to have some beneficial effects on health. Forty-five clinically healthy subjects were included in a randomized, double-blinded crossover trial aimed at evaluating the effect of a replacement diet with bread derived from ancient grain varieties versus modern grain variety on cardiovascular risk profile. After 8 weeks of intervention, consumption of bread obtained by the ancient varieties showed a significant amelioration of various cardiovascular parameters. Indeed, the ancient varieties were shown to result in a significant reduction of total cholesterol, low-density lipoprotein (LDL)-cholesterol and blood glucose, whereas no significant differences during the phase with the modern variety were reported. Moreover, a significant increase in circulating endothelial progenitor cells were reported after the consumption of products made from the ancient "Verna" variety. The present results suggest that a dietary consumption of bread obtained from ancient grain varieties was effective in reducing cardiovascular risk factors. PMID- 27687520 TI - Polyester hydrolysis is enhanced by a truncated esterase: Less is more. AB - An esterase from Clostridium botulinum (Cbotu_EstA) previously reported to hydrolyze the biodegradable polyester poly(butylene adipate-co-terephthalate) was redesigned to improve the hydrolysis of synthetic polyesters. Increased activity was indeed observed for del71Cbotu_EstA variant, which performed activity on the widespread polyester polyethylene terephthalate, which was not able to be attacked by the wild-type enzyme Cbotu_EstA. Analysis of the 3D structure of the enzyme showed that removing 71 residues at the N-terminus of the enzyme exposed a hydrophobic patch on the surface and improved sorption of hydrophobic polyesters concomitantly facilitating the access of the polymer to the active site. These results show a new route for enhancing enzyme activity for hydrolysis and modification of polyesters. PMID- 27687521 TI - Tongue Strength is Associated with Grip Strength and Nutritional Status in Older Adult Inpatients of a Rehabilitation Hospital. AB - The aim of this cross-sectional study was to investigate whether tongue strength observed in older adult inpatients of a rehabilitation hospital is associated with muscle function, nutritional status, and dysphagia. A total of 174 older adult inpatients aged 65 years and older in rehabilitation (64 men, 110 women; median age, 84 years; interquartile range, 80-89 years) who were suspected of having reduced tongue strength due to sarcopenia were included in this study. Isometric tongue strength was measured using a device fitted with a disposable oral balloon probe. We evaluated age, muscle function as assessed by the Barthel index and grip strength, nutritional status as measured by the Mini Nutritional Assessment-short form (MNA-SF), body mass index, serum albumin, controlling nutritional status, and calf circumference and arm muscle area to assess muscle mass. In addition, the functional oral intake scale (FOIS) was used as an index of dysphagia. Multivariate linear regression analysis revealed that isometric tongue strength was independently associated with grip strength (coefficient = 0.33, 95 % confidence interval (CI) 0.12-0.54, p = 0.002), MNA-SF (coefficient = 0.74, 95 % CI 0.12-1.35, p = 0.019), and FOIS (coefficient = 0.02, 95 % CI 0.00 0.15, p = 0.047). To maintain and improve tongue strength in association with sarcopenic dysphagia, exercise therapy and nutritional therapy interventions, as well as direct interventions to address tongue strength, may be effective in dysphagia rehabilitation in older adult inpatients.

AB - Some patients with Guillain-Barre syndrome require respiratory management by tracheotomy and/or nutritional management by tube feeding; however, few studies have reported the follow-up course in these patients. The objective of this study was to investigate the follow-up course of tracheotomy and gastrostomy in patients with Guillain-Barre syndrome. The study subjects were 50 patients with Guillain-Barre syndrome (25 males, 25 females; mean age, 51.1 +/- 18.7 years) who were admitted to the Hiroshima City Rehabilitation Hospital during the period from April 2008 to December 2015. We retrospectively reviewed the medical records to determine the presence or absence of tracheotomy and/or feeding tube, and the timing of withdrawal from these treatments. During the acute phase, 15 patients underwent tracheotomy and 14 underwent tube feeding management. A tracheotomy tube was inserted for 110 days or longer in five patients, and four of these five patients also had a gastrostomy tube inserted. Among the 14 patients in the tube feeding group, seven underwent nasal feeding and seven underwent percutaneous endoscopic gastrostomy. All patients had the nasal tube removed (mean duration of nasal tube placement, 62.1 +/- 46.5 days); however, the gastrostomy tube could not be removed in two patients. Our findings indicate that patients in the acute phase of Guillain-Barre syndrome carry a relevant risk of long-term tube feeding and prolonged need of an artificial airway.

AB - From a population-based cohort of cases of first cancers diagnosed between 1987 and 2004, before the patient's age of 15 years, the authors conducted a nested case-control study, matching 64 patients who experienced a second malignant neoplasm (SMN) with 190 controls. SMNs comprised 10 leukemia or myelodysplastic syndromes, 5 lymphomas induced by Epstein-Barr virus after allograft, and 49 solid tumors, including mainly 25 carcinomas (17 of the thyroid), 9 bone sarcomas, and 7 central nervous system (CNS) tumors. The median latency occurrence was 6.5 years, and that of thyroid carcinomas induced by 12 Gy fractioned total body irradiation (TBI) was 7.6 years. The relative risk (RR) of an SMN was increased by genetic and family factors and increased 17 to 69 times according to the dose of radiotherapy administered in the region for the first cancer. Age younger than 4 years at the time of radiotherapy increased the risk of SMN. Chemotherapy adjusted according to the dose of radiotherapy administered in the field yielded a greater RR of an SMN only for cumulative doses exceeding 2 g/m2 of epipodophyllotoxin but not for alkylating agents or platinum compounds. The RR of secondary leukemia increased 10-fold following high doses of epipodophyllotoxin >2 g/m2 but was not affected by alkylating agents or anthracyclines. The crude RR of a solid SMN developing after radiotherapy was very high at 18 and reached 90.7 for thyroid carcinoma after TBI, whereas the authors observed no increased risk associated with chemotherapy. These results confirm the risk of secondary leukemia after epipodophyllotoxin and of solid tumor after radiotherapy.

AB - Individual spatial positioning plays an important role in mediating the costs and benefits of group living, and thus shapes different aspects of animal social systems including group structure and cohesiveness. I aimed to quantify variation in individual spacing behavior and its correlates in a group of wild patas monkeys (Erythrocebus patas) living in north Cameroon. I collected data on inter individual distances during group scans when following subject females. Individuals had longer inter-individual distances during the non-birth season than during the birth season. Dominance relationships had little effect on inter individual distances between females during both the non-birth and birth seasons. The results suggest that group cohesion was higher during the birth season than the non-birth season. Thus I conclude that higher group cohesion during the birth season may reduce the predation risk of infants. PMID- 27687525 TI - Microglia energy metabolism in metabolic disorder. AB - Microglia are the resident macrophages of the CNS, and are in charge of maintaining a healthy microenvironment to ensure neuronal survival. Microglia carry out a non-stop patrol of the CNS, make contact with neurons and look for abnormalities, all of which requires a vast amount of energy. This non-signaling energy demand increases after activation by pathogens, neuronal damage or other kinds of stimulation. Of the three major energy substrates - glucose, fatty acids and glutamine - glucose is crucial for microglia survival and several glucose transporters are expressed to supply sufficient glucose influx. Fatty acids are another source of energy for microglia and have also been shown to strongly influence microglial immune activity. Glutamine, although possibly suitable for use as an energy substrate by microglia, has been shown to have neurotoxic effects when overloaded. Microglial fuel metabolism might be associated with microglial reactivity under different pathophysiological conditions and a microglial fuel switch may thus be the underlying cause of hypothalamic dysregulation, which is associated with obesity. PMID- 27687526 TI - Assessment of patient safety culture: what tools for medical students? AB - BACKGROUND: The assessment of patient safety culture refers mainly to surveys exploring the perceptions of health professionals in hospitals. These surveys have less relevance when considering the assessment of the patient safety culture of medical students, especially at university or medical school. They are indeed not fully integrated in care units and constitute a heterogeneous population. This work aimed to find appropriate assessment tools of the patient safety culture of medical students. METHODS: Systematic review of the literature. Surveys related to a care unit were excluded. A typology of the patient safety culture of medical students was built from the included surveys. RESULTS: Eighteen surveys were included. In our typology of patient safety culture of medical students (15 dimensions), the number of dimensions explored by survey (n) ranged from 1 to 12, with 6 "specialized" tools (n <= 4) and 12 "global" tools (N >= 5). These surveys have explored: knowledge about patient safety, acknowledgment of the inevitability of human error, the lack of skills as the main source of errors, the errors reporting systems, disclosure of medical errors to others health professionals or patients, teamwork and patient involvement to improve safety in care. CONCLUSIONS: We recommend using Wetzel's survey for making an overall assessment of the patient safety culture of medical students at university. In a specific purpose-e.g. to assess an educational program on medical error disclosure-the authors recommend to determine which dimensions of patient safety will be taught, to select the best assessment tool. Learning on patient safety should however be considered beyond the university. International translations of tools are required to create databases allowing comparative studies. PMID- 27687527 TI - Evaluation of the brain-penetrant microtubule-stabilizing agent, dictyostatin, in the PS19 tau transgenic mouse model of tauopathy. AB - Neurodegenerative disorders referred to as tauopathies, which includes Alzheimer's disease (AD), are characterized by insoluble deposits of the tau protein within neuron cell bodies and dendritic processes in the brain. Tau is normally associated with microtubules (MTs) in axons, where it provides MT stabilization and may modulate axonal transport. However, tau becomes hyperphosphorylated and dissociates from MTs in tauopathies, with evidence of reduced MT stability and defective axonal transport. This has led to the hypothesis that MT-stabilizing drugs may have potential for the treatment of tauopathies. Prior studies demonstrated that the brain-penetrant MT-stabilizing drug, epothilone D, had salutary effects in transgenic (Tg) mouse models of tauopathy, improving MT density and axonal transport, while reducing axonal dystrophy. Moreover, epothilone D enhanced cognitive performance and decreased hippocampal neuron loss, with evidence of reduced tau pathology. To date, epothilone D has been the only non-peptide small molecule MT-stabilizing agent to be evaluated in Tg tau mice. Herein, we demonstrate the efficacy of another small molecule brain-penetrant MT-stabilizing agent, dictyostatin, in the PS19 tau Tg mouse model. Although dictyostatin was poorly tolerated at once-weekly doses of 1 mg/kg or 0.3 mg/kg, likely due to gastrointestinal (GI) complications, a dictyostatin dose of 0.1 mg/kg was better tolerated, such that the majority of 6 month old PS19 mice, which harbor a moderate level of brain tau pathology, completed a 3-month dosing study without evidence of significant body weight loss. Importantly, as previously observed with epothilone D, the dictyostatin treated PS19 mice displayed improved MT density and reduced axonal dystrophy, with a reduction of tau pathology and a trend toward increased hippocampal neuron survival relative to vehicle-treated PS19 mice. Thus, despite evidence of dose limiting peripheral side effects, the observed positive brain outcomes in dictyostatin-treated aged PS19 mice reinforces the concept that MT-stabilizing compounds have significant potential for the treatment of tauopathies. PMID- 27687528 TI - Respiratory health effects of occupational exposure to charcoal dust in Namibia. AB - BACKGROUND: Charcoal processing activities can increase the risk of adverse respiratory outcomes. OBJECTIVE: To determine dose-response relationships between occupational exposure to charcoal dust, respiratory symptoms and lung function among charcoal-processing workers in Namibia. METHODS: A cross-sectional study was conducted with 307 workers from charcoal factories in Namibia. All respondents completed interviewer-administered questionnaires. Spirometry was performed, ambient and respirable dust levels were assessed in different work sections. Multiple logistic regression analysis estimated the overall effect of charcoal dust exposure on respiratory outcomes, while linear regression estimated the exposure-related effect on lung function. Workers were stratified according to cumulative dust exposure category. RESULTS: Exposure to respirable charcoal dust levels was above occupational exposure limits in most sectors, with packing and weighing having the highest dust exposure levels (median 27.7 mg/m3, range: 0.2-33.0 for the 8-h time-weighted average). The high cumulative dust exposure category was significantly associated with usual cough (OR: 2.1; 95% CI: 1.1 4.0), usual phlegm (OR: 2.1; 95% CI: 1.1-4.1), episodes of phlegm and cough (OR: 2.8; 95% CI: 1.1-6.1), and shortness of breath. A non-statistically significant lower adjusted mean-predicted % FEV1 was observed (98.1% for male and 95.5% for female) among workers with greater exposure. CONCLUSIONS: Charcoal dust levels exceeded the US OSHA recommended limit of 3.5 mg/m3 for carbon-black-containing material and study participants presented with exposure-related adverse respiratory outcomes in a dose-response manner. Our findings suggest that the Namibian Ministry of Labour introduce stronger enforcement strategies of existing national health and safety regulations within the industry. PMID- 27687529 TI - Birth Outcomes Among U.S. Women With Hearing Loss. AB - INTRODUCTION: The purpose of this study is to estimate the national occurrence of deliveries in women with hearing loss and to compare their birth outcomes to women without hearing loss. METHODS: This study examined the 2008-2011 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project in 2015 to compare birth outcomes in women with hearing loss and without. Birth outcomes included preterm birth and low birth weight. Multivariate regression analyses compared birth outcomes between women with and without hearing loss, controlling for maternal age, racial and ethnic identity, type of health insurance, comorbidity, region of hospital, location and teaching status of the hospital, ownership of the hospital, and median household income for mother's ZIP code. RESULTS: Of an estimated 17.9 million deliveries, 10,462 occurred in women with hearing loss. In adjusted regression analyses controlling for demographic characteristics, women with hearing loss were significantly more likely than those without hearing loss to have preterm birth (OR=1.28, 95% CI=1.08, 1.52, p<0.001) and low birth weight (OR=1.43, 95% CI=1.09, 1.90, p<0.05). CONCLUSIONS: This study provides a first examination of the pregnancy outcomes among women with hearing loss in the U.S. This analysis demonstrates significant disparities in birth outcomes between women with and without hearing loss. Understanding and addressing the causes of these disparities is critical to improving pregnancy outcomes among women with hearing loss. PMID- 27687530 TI - Wip 1 inhibits intestinal inflammation in inflammatory bowel disease. AB - Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is a chronically intestinal autoimmune disease, the pathological mechanisms of which are not very clear. Wild type p-53 induced phosphatase 1 (Wip1), a serine/threonine protein phosphatase, has been reported to negatively regulate the inflammation in sepsis. However, the role of Wip1 in IBD is not very clear. Therefore, colonic tissues and peripheral blood from patients with IBD and healthy controls were collected to analyzed mRNA and protein expression of Wip1 using the method of qPCR and immunohistochemistry. Immune cells of neutrophils, CD4+ T cells, CD8+ T cells, B cells, monocytes and intestinal epithelial cells were isolated to analyze Wip1 expression by means of qPCR. Expression of Wip 1 was analyzed after the cells were stimulated by various of cytokines. DSS-colitis model was induced on the wild type (WT) and Wip 1 knock out (Wip1-/-) mice, and cytokines expression were analyzed in intestinal lamina propria from WT and Wip1 /- mice. Neutrophil specific markers were examined in intestinal lamina propria from WT and Wip1-/- mice. Moreover, neutrophils were isolated from bone marrow of WT and Wip1-/- mice to examine neutrophil migration with or without inhibitors of signaling pathway in vitro. The expression of Wip 1 mRNA and protein were found to be significantly decreased in patients with active IBD compared with healthy controls. And Wip 1 was mainly expressed on neutrophils from peripheral blood and colonic tissues. Moreover, expression of Wip1 was significantly decreased on neutrophils after the stimulation of TNF-alpha and IFN-gamma. Wip1-/- mice were more susceptible to DSS induced colitis compared to WT mice, and expressed more pro-inflammatory cytokines (e.g. TNF-alpha, IFN-gamma, IL-17A, etc). Moreover, expression of neutrophil specific markers (e.g. Ly6G, CD11b, elastase, etc) was also increased in Wip1-/- mice. The migration of neutrophils from the bone marrow of Wip1 mice was marked increased, which was mediated by MAPK-P38 signaling pathway. Wip1 plays an importantly protective role in the pathogenesis of IBD. Therefore, Wip1 may be used a new targets in the treatment for IBD in the future. PMID- 27687531 TI - Long-term outcomes of the Kropp and Salle urethral lengthening bladder neck reconstruction procedures. AB - INTRODUCTION: The Kropp and Salle procedures have shown good short-term outcomes for managing neuropathic urinary incontinence. However, few studies have assessed their long-term results. OBJECTIVE: This study aimed to evaluate the long-term outcomes of Kropp and Salle procedures, including: dryness, secondary interventions for incontinence or complications, upper urinary tract changes, and use of urethral catheterizations. STUDY DESIGN: Consecutive patients undergoing Kropp and Salle procedures at the present institution (1983-2012) were retrospectively reviewed. Patients with <1-year follow-up or prior bladder neck (BN) continence procedures were excluded. Data were collected on postoperative dryness per urethra at 4-hourly and 3-hourly intervals, secondary interventions, lab tests, and imaging. Non-parametric tests were used for statistical analysis. RESULTS: Thirty-eight patients had Kropp (K: 30 boys) and 12 had Salle procedures (S: 8 boys). Patients underwent surgery at similar median ages (K: 7.4 vs S: 8.7 years old, P = 0.51) and had similar median follow-up (6.9 vs 10.3 years, P = 0.10). Most patients had myelomeningocele, a prior/concomitant bladder augmentation (K: 73.7%, S: 58.3%) and catheterizable channel (K: 81.6%, S: 50.0%). Differences in all outcomes between Kropp and Salle procedures were statistically non-significant. The majority of patients did not have additional BN procedures for dryness (K: 84.2%, S: 66.7%). Of this group, K: 81.3% and S: 75.0% were dry for >=4 h, K: 93.8% and S: 87.5% were dry for >=3 h between catheterizations (Table). Of the minority of patients who underwent additional BN procedures for dryness (K: 15.8%, S: 33.3%), most achieved dryness for >=4 h (K: 66.7%, S: 100%) and >=3 h (100% for both). Among patients without an initial catheterizable channel, 57.1% had one subsequently created after a Kropp procedure, and 33.3% after a Salle. Among patients without bladder augmentation, approximately half underwent delayed augmentation (K: 50.0%, S: 40.0%). Ultimately, most patients required a secondary intervention under anesthesia for incontinence or complications (K: 79.0%, S: 66.7%). Few patients developed worsening hydronephrosis, vesicoureteral reflux or renal function (K: 2.6%, S: 0.0%). At the end of follow-up, few patients catheterized per urethra (K: 10.5%, S: 33.3%). DISCUSSION: This was a retrospective study without urodynamic data. Originating from a tertiary center, the results may not apply to other clinical settings. CONCLUSIONS: At the present institution the Kropp and Salle procedures attained similar dryness in 75-81% at 4-hourly intervals and 88-94% at 3-hourly intervals without additional BN procedures. Few patients required subsequent BN procedures to achieve dryness. However, the overall need for secondary procedures during long-term follow-up was high for both procedures. PMID- 27687532 TI - Management of undescended testes: European Association of Urology/European Society for Paediatric Urology Guidelines. AB - CONTEXT: Undescended testis is the most common endocrinological disease in the male newborn period. Incidence varies between 1.0% and 4.6% in full-term neonates, with rates as high as 45% in preterm neonates. Failure or delay of treatment can result in reduced fertility and/or increased testicular cancer risk in adulthood. OBJECTIVE: To provide recommendations for the diagnosis and treatment of boys with undescended testes which reduce the risk of impaired fertility and testicular cancer in adulthood. EVIDENCE ACQUISITION: Embase and Pubmed were searched for all relevant publications, from 1990 to 2015 limited to English language. Data were narratively synthesized in light of methodological and clinical heterogeneity. The risk of bias of each included study was assessed. EVIDENCE SYNTHESIS: There is consensus that early treatment, by 18 months at the latest, for undescended testes is mandatory to avoid possible sequelae regarding fertility potential and cancer risk. The current standard therapy is orchidopexy, while hormonal therapy is still under debate. However, in some individuals the successful scrotal placement of previously undescended testes may not prevent potential negative long-term outcomes regarding fertility and testicular malignancy. CONCLUSIONS: There is good evidence for early placement of undescended testes in the scrotal position to prevent potential impairment of fertility and reduce the risk of testicular malignancy. No consensus exists on the various forms of hormonal treatment, which are assessed on an individual basis. PMID- 27687533 TI - Robotic-assisted laparoscopic bladder augmentation in the pediatric patient. AB - INTRODUCTION: Bladder augmentation is a common surgical intervention for neuropathic bladder dysfunction, and has conventionally been an open procedure. We present a robotic ileocystoplasty to demonstrate the feasibility of an entirely intracorporeal approach in a pediatric patient. METHODS: The patient was a 6 year old (18.5 kg) boy with a neurogenic bladder secondary to lumbar myelomeningocele. Urodynamics revealed a small capacity and poorly compliant bladder and he was incontinent between frequent catheterizations. A robotic augmentation cystoplasty was performed. RESULTS: At one-month postoperatively, a cystogram revealed no urine leak, and the suprapubic tube was removed. The patient resumed CIC every 3 h during the day and once overnight until postoperative urodynamic studies confirmed safe dynamics, after which the CIC interval was lengthened. CONCLUSION: Robotic bladder augmentation is safe and feasible in a select pediatric population. The entire procedure including preparation of the bowel segment can be completed intracorporeally, even in smaller children. PMID- 27687534 TI - Characterizing the intersection of Co-occurring risk factors for illicit drug abuse and dependence in a U.S. nationally representative sample. AB - Few studies have attempted to characterize how co-occurring risk factors for substance use disorders intersect. A recent study examined this question regarding cigarette smoking and demonstrated that co-occurring risk factors generally act independently. The present study examines whether that same pattern of independent intersection of risk factors extends to illicit drug abuse/dependence using a U.S. nationally representative sample (National Survey on Drug Use and Health, 2011-2013). Logistic regression and classification and regression tree (CART) modeling were used to examine risk of past-year drug abuse/dependence associated with a well-established set of risk factors for substance use (age, gender, race/ethnicity, education, poverty, smoking status, alcohol abuse/dependence, mental illness). Each of these risk factors was associated with significant increases in the odds of drug abuse/dependence in univariate logistic regressions. Each remained significant in a multivariate model examining all eight risk factors simultaneously. CART modeling of these 8 risk factors identified subpopulation risk profiles wherein drug abuse/dependence prevalence varied from <1% to >80% corresponding to differing combinations of risk factors present. Alcohol abuse/dependence and cigarette smoking had the strongest associations with drug abuse/dependence risk. These results demonstrate that co-occurring risk factors for illicit drug/abuse dependence generally intersect in the same independent manner as risk factors for cigarette smoking, underscoring further fundamental commonalities across these different types of substance use disorders. These results also underscore the fundamental importance of differences in the presence of co-occurring risk factors when considering the often strikingly different prevalence rates of illicit drug abuse/dependence in U.S. population subgroups. PMID- 27687536 TI - A comprehensive scoring system to measure healthy community design in land use plans and regulations. AB - Comprehensive land use plans and their corresponding regulations play a role in determining the nature of the built environment and community design, which are factors that influence population health and health disparities. To determine the level in which a plan addresses healthy living and active design, there is a need for a systematic, reliable and valid method of analyzing and scoring health related content in plans and regulations. This paper describes the development and validation of a scoring tool designed to measure the strength and comprehensiveness of health-related content found in land use plans and the corresponding regulations. The measures are scored based on the presence of a specific item and the specificity and action-orientation of language. To establish reliability and validity, 42 land use plans and regulations from across the United States were scored January-April 2016. Results of the psychometric analysis indicate the scorecard is a reliable scoring tool for land use plans and regulations related to healthy living and active design. Intraclass correlation coefficients (ICC) scores showed strong inter-rater reliability for total strength and comprehensiveness. ICC scores for total implementation scores showed acceptable consistency among scorers. Cronbach's alpha values for all focus areas were acceptable. Strong content validity was measured through a committee vetting process. The development of this tool has far-reaching implications, bringing standardization of measurement to the field of land use plan assessment, and paving the way for systematic inclusion of health-related design principles, policies, and requirements in land use plans and their corresponding regulations. PMID- 27687535 TI - Impact of provider-patient communication on cancer screening adherence: A systematic review. AB - Cancer screening is critical for early detection and a lack of screening is associated with late-stage diagnosis and lower survival rates. The goal of this review was to analyze studies that focused on the role of provider-patient communication in screening behavior for cervical, breast, and colorectal cancer. A comprehensive search was conducted in four online databases between 1992 and 2016. Studies were included when the provider being studied was a primary care provider and the communication was face-to-face. The search resulted in 3252 records for review and 35 articles were included in the review. Studies were divided into three categories: studies comparing recommendation status to screening compliance; studies examining the relationship between communication quality and screening behavior; and intervention studies that used provider communication to improve screening behavior. There is overwhelming evidence that provider recommendation significantly improves screening rates. Studies examining quality of communication are heterogeneous in method, operationalization and results, but suggest giving information and shared decision making had a significant relationship with screening behavior. Intervention studies were similarly heterogeneous and showed positive results of communication interventions on screening behavior. Overall, results suggest that provider recommendation is necessary but not sufficient for optimal adherence to cancer screening guidelines. Quality studies suggest that provider-patient communication is more nuanced than just a simple recommendation. Discussions surrounding the recommendation may have an important bearing on a person's decision to get screened. Research needs to move beyond studies examining recommendations and adherence and focus more on the relationship between communication quality and screening adherence. PMID- 27687537 TI - Repletion of vitamin D associated with deterioration of sleep quality among postmenopausal women. AB - Reduced health-related quality of life (HRQOL), depressive symptoms and poor sleep quality are important health issues among postmenopausal women and may be associated with low vitamin D status. Overweight postmenopausal women, with serum 25-hydroxyvitamin D [25(OH)D] 10-32ng/m, were recruited in Seattle, WA (2010 2012) and randomly assigned to 12months of weight loss +2000IU oral vitamin D3/day or weight loss+daily placebo. The weight-loss program included a reduced calorie diet and 225min/week of moderate-to-vigorous aerobic activity. Eight subscales of HRQOL were assessed by the MOS 36-Item Short-Form Health Survey. Depressive symptoms were assessed using the Brief Symptom Inventory-18, and sleep quality was assessed using the Pittsburg Sleep Quality Index (PSQI). Mean 12 month changes in HRQOL, depressive symptoms and sleep quality were compared between groups (intent-to-treat) using generalized estimating equations. Compared to placebo, women receiving vitamin D did not experience any significant change in depressive symptoms (p=0.78), HRQOL subscales (all p>0.05), or overall sleep quality (p=0.21). However, a greater magnitude of change in serum 25(OH)D was associated with an increased need to take medications to sleep (ptrend=0.01) and overall worse sleep quality (ptrend<0.01). Women who became vitamin D replete (>=32ng/mL) also showed a deterioration in total PSQI sleep quality score compared to women who remained <32ng/mL despite supplementation, even after adjusting for relevant covariates (Non-Replete: -5.7% vs. Replete: +6.2%, p<0.01). Vitamin D supplementation of 2000IU/d may result in overall worse sleep quality for postmenopausal women with low circulating vitamin D undergoing weight loss. PMID- 27687538 TI - Effectiveness of a scaled up physical activity intervention in Brazil: A natural experiment. AB - Physical inactivity causes 5.3 million deaths annually worldwide. We evaluated the impact on population leisure-time physical activity (LTPA) of scaling up an intervention in Brazil, Academia das Cidades program (AC-P). AC-P is a health promotion program classified as physical activity classes in community settings which started in the state of Pernambuco state in 2008. We surveyed households from 80 cities of Pernambuco state in 2011, 2012 and 2013, using monitoring data to classify city-level exposure to AC-P. We targeted 2370 individuals in 2011; 3824 individuals in 2012; and 3835 individuals in 2013. We measured participation in AC-P and whether respondents had seen an AC-P activity or heard about AC-P. We measured LTPA using the International Physical Activity Questionnaire. We estimated the odds of reaching recommended LTPA by levels of exposure to the three AC-P measures. For women, the odds of reaching recommended LTPA were 1.10 for those living in cities with AC-P activity for less than three years, and 1.46 for those living in cities with AC-P activity for more than three years compared to those living in cities that had not adopted AC-P. The odds of reaching recommended LTPA increased with AC-P participation and knowledge about AC-P. AC-P exposure is associated with increased population LTPA. Extending AC-P to all cities could potentially impact non-communicable diseases in Brazil. PMID- 27687539 TI - The MacTRAUMA TTL Assessment Tool: Developing a Novel Tool for Assessing Performance of Trauma Trainees: Initial Reliability Testing. AB - OBJECTIVES: To develop a novel assessment tool for trainees-led trauma resuscitation. Assess psychometric properties of the proposed tool. Evaluate feasibility and utility of the tool. INTRODUCTION: Trauma resuscitation is a structured and complex process involving unique sets of skills. There is currently no published structured formative evaluation tool for trauma trainees. Therefore, many trauma trainees rely upon limited, unstructured feedback on their performance. We developed a tool to assess trainee performance while leading a trauma resuscitation and to assist faculty in providing trainee feedback after the encounter. METHODS: This study was conducted in a level I trauma centre in Ontario, Canada. Principles of learning theories, literature review, and clinical expert opinions were used to design a tool to assess clinical competence required to lead the resuscitation. In total, 5 critical domains were identified. High fidelity simulation-based environment was used to test interrater reliability using intraclass correlation coefficients. To gauge feasibility, practicality, and utility of the tool, an online survey was sent to raters and trainees at the end of the study. RESULTS: We found "excellent" agreement for "initial critical assessment" domain (0.80) and "moderate to good" agreement for the "communication and leadership" (0.67) and "clinical performance" domains (0.53). "Poor" agreement was identified for the "decision-making" domain (0.33). The coefficients for individual items reached "good" agreement for 5 items, and "moderate" agreement for 8 items. Intraclass correlation coefficients for the remaining 7 items were "fair" or "poor." Most raters agreed that items in the medical training domain were not applicable. Feedback from raters and trainees confirmed the feasibility and acceptability of the tool for formative feedback, in addition to some suggestions to enhance the tool. CONCLUSION: MacTrauma TTL assessment tool is a novel tool for formative feedback for trainees' performance during trauma resuscitation. Initial psychometric property testing is promising. Further reliability and validity testing of the modified tool is needed. The tool has been shown to be feasible and acceptable by both trainees and faculty as a formative assessment tool. PMID- 27687540 TI - Analysis of Practice Settings for Craniofacial Surgery Fellowship Graduates in North America. AB - OBJECTIVE: In North America, the number of craniofacial surgery fellowship graduates is increasing, yet an analysis of practice settings upon graduation is lacking. We characterize the practice types of recent graduates of craniofacial fellowship programs in the United States and Canada. DESIGN: A 6-year cohort of craniofacial fellows in the United States and Canada (2010-2016) were obtained from craniofacial programs recognized by the American Society of Craniofacial Surgery. Practice setting was determined at 1 and 3 years of postgraduation, and predictors of practice setting were determined. RESULTS: A total of 175 craniofacial surgeons were trained at 35 fellowship programs. At 1 year of postgraduation, 33.6% had an academic craniofacial position and 27.1% were in private practice (p = 0.361). A minority of graduates pursued additional fellowships (16.4%), nonacademic craniofacial positions (10.0%), academic noncraniofacial positions (5.7%), and international practices (7.1%). At 3 years of postgraduation, the percentage of graduates in academic craniofacial positions was unchanged (34.5% vs 33.6%, p = 0.790). The strongest predictors of future academic craniofacial practice were completing plastic surgery residency at a program with a craniofacial fellowship program (odds ratio = 6.78, p < 0.001) and completing an academic craniofacial fellowship program (odds ratio = 4.48, p = 0.020). CONCLUSIONS: A minority of craniofacial fellowship graduates practice academic craniofacial surgery. A strong academic craniofacial surgery background during residency and fellowship is associated with a future career in academic craniofacial surgery. These data may assist trainees choose training programs that align with career goals and educators select future academic surgeons. PMID- 27687541 TI - Cholesterol-rich membrane microdomains modulate Wnt/beta-catenin morphogen gradient during Xenopus development. AB - Wnt/beta-catenin has been described as crucial for dorsal-ventral and antero posterior patterning, playing multiple roles at different stages of development. Cholesterol-rich membrane microdomains (CRMMs), cholesterol- and sphingolipid enriched domains of the plasma membrane, are known as platforms for signaling pathways. Although we have demonstrated the importance of the CRMMs for head development, how they participate in prechordal plate formation and embryo axis patterning remains an open question. Moreover, the participation of the CRMMs in the Wnt/beta-catenin signaling pathway activity in vivo is unclear, particularly during embryonic development. In this study, we demonstrated that CRMMs disruption by methyl-beta-cyclodextrin (MbetaCD) potentiates the activation of the Wnt/beta-catenin signaling pathway in vitro and in vivo during embryonic development, causing head defects by expanding the Wnt expression domain. Furthermore, we also found that the action of CRMMs depends on the microenvironmental context because it also works in conjunction with dkk1, when dkk1 is overexpressed. Thus, we propose CRMMs as a further mechanism of prechordal plate protection against the Wnt signals secreted by posterolateral cells, complementing the action of secreted antagonists.

PMID- 27687543 TI - Evaluation of beta-blockers and survival among hypertensive patients with renal cell carcinoma. AB - OBJECTIVES: Beta-blocker use is associated with improved survival for multiple nonurologic malignancies. Our objective was to evaluate the association between beta-blocker use and survival among surgically managed hypertensive patients with clear-cell renal cell carcinoma (ccRCC). METHODS: Hypertensive patients with ccRCC treated with either radical or partial nephrectomy between 2000 and 2010 were identified from our Nephrectomy Registry. Beta-blocker use within 90 days before surgery was identified. The associations between beta-blocker use and risk of disease progression, death from renal cell carcinoma (RCC), and all-cause mortality were assessed using Cox proportional hazards regression models. RESULTS: In total, 913 hypertensive patients were identified who underwent either partial or radical nephrectomy for ccRCC. Of these, 104 (11%) had documented beta blocker use within 90 days before surgery. At last follow-up (median 8.2y among survivors), 258 patients showed progression (median 1.6y following surgery), and 369 patients had died (median 4.1y following surgery), including 138 who died of RCC. After adjusting for PROG (progression-free survival) and SSIGN (cancer specific survival) scores, beta-blocker use was not significantly associated with the risk of disease progression (hazard ratio [HR] = 0.94; 95% CI: 0.61-1.47; P = 0.80) or the risk of death from RCC (HR = 0.74; 95% CI: 0.38-1.41; P = 0.35). Similarly, on multivariable analysis adjusting for clinicopathologic features, there was not a significant association between beta-blocker use and the risk of all-cause mortality (HR = 0.83; 95% CI: 0.59-1.16; P = 0.27). CONCLUSIONS: Beta blocker use for hypertension within 90 days before surgery was not associated with the risk of progression, death from RCC, or death from any cause. PMID- 27687544 TI - Effect of delayed resection after initial surveillance and tumor growth rate on final surgical pathology in patients with small renal masses (SRMs). AB - OBJECTIVE: To understand potential harms associated with delaying resection of small renal masses (SRMs) in patients ultimately treated, and whether these patients have factors associated with adverse pathology. METHODS: Patients with SRMs (<=4cm) who underwent surgical resection at our institution (2009-2015) were classified as undergoing early resection or initial surveillance with delayed resection (defined by a time from presentation to intervention of at least 6mo). Demographic and clinical variables were compared among groups. Using multivariable logistic regression, we examined the association between delayed resection and adverse pathology (Fuhrman grade 3-4, papillary type 2, sarcomatoid histology, angiomyolipoma with epithelioid features, or stage>=pT3). For patients who underwent delayed intervention, we used similar methods to examine the association between SRM growth rate and adverse pathology. RESULTS: Overall, 401 (81%) and 94 (19%) patients underwent early and delayed resection, respectively. Median time to resection was 84 days (interquartile range: 59-121) and 386 days (interquartile range: 272-702) (P<0.001). Patients undergoing delayed resection were older (62 vs. 58y, P = 0.01) and had smaller masses (2.3 vs. 2.7cm, P<0.001) at initial presentation. Utilization of partial vs. radical nephrectomy was similar regardless of resection timing (P = 0.5). Delayed resection was not associated with adverse pathology (P = 0.8); however, male sex was independently associated with adverse pathology (odds ratio: 1.7, 95% CI: 1.1-2.4, P = 0.009). In patients on surveillance, increasing annual SRM growth rate was associated with adverse pathology (odds ratio: 1.2, 95% CI: 1.03-1.3mm/y, P = 0.02). CONCLUSIONS: Delayed resection was not associated with adverse pathology. Patients on surveillance with increased SRM growth rates had a modest but significant increase in the risk of adverse pathology.

AB - Paclitaxel (PTX) is a microtubule-targeting drug widely used for the treatment of a variety of cancers. However, drug resistance can emerge after a series of treatments, and this can seriously affect the patient's prognosis. Here, we analyzed the mechanism of PTX resistance using a human prostate cancer cell line, PC3, and its PTX-resistant subline, PC3-PR. Compared with PC3, PC3-PR exhibited some unique phenotypes that might be associated with PTX resistance, including decreased expression of acetylated alpha-tubulin and the cell cycle regulator p21, and increased expression of betaIII tubulin, histone deacetylase 6 (HDAC6), and the anti-apoptotic protein Bcl2. The drug exporters MDR1 and MRP1 were not involved in PTX resistance. Although cabazitaxel (CTX), a novel taxoid, has been reported to overcome PTX resistance, its mechanism of action is unknown. We found that treatment of PC3-PR cells with CTX induced expression of acetylated alpha tubulin and p21, but not the related regulators p27, p15, and p16 or the Bcl2 family proteins. The pan-HDAC inhibitors trichostatin A and suberanilohydroxamic acid and the HDAC6-specific inhibitor tubacin inhibited PC3-PR proliferation and increased expression of p21 and acetylated alpha-tubulin in a manner similar to CTX. Our data shed light on the cellular response to PTX and CTX. PMID- 27687546 TI - Wnt4 antagonises Wnt3a mediated increases in growth and glucose stimulated insulin secretion in the pancreatic beta-cell line, INS-1. AB - The Wnt signalling pathway in beta-cells has been linked to the development of type 2 diabetes. Investigating the impact of a non-canonical Wnt ligand, Wnt4, on beta-cell function we found that in INS-1 cells, Wnt4 was able to completely block Wnt3a stimulated cell growth and insulin secretion. However, despite high levels of Wnt4 protein being detected in INS-1 cells, reducing the expression of Wnt4 had no impact on cell growth or Wnt3a signalling. As such, the role of the endogenously expressed Wnt4 in beta-cells is unclear, but the data showing that Wnt4 can act as a negative regulator of canonical Wnt signalling in beta-cells suggests that this pathway could be a potential target for modulating beta-cell function. PMID- 27687547 TI - Chemotherapy impedes in vitro microcirculation and promotes migration of leukemic cells with impact on metastasis. AB - Although most cancer drugs target the proliferation of cancer cells, it is metastasis, the complex process by which cancer cells spread from the primary tumor to other tissues and organs of the body where they form new tumors, that leads to over 90% of all cancer deaths. Thus, there is an urgent need for anti metastasis therapy. Surprisingly, emerging evidence suggests that certain anti cancer drugs such as paclitaxel and doxorubicin can actually promote metastasis, but the mechanism(s) behind their pro-metastatic effects are still unclear. Here, we use a microfluidic microcirculation mimetic (MMM) platform which mimics the capillary constrictions of the pulmonary and peripheral microcirculation, to determine if in-vivo-like mechanical stimuli can evoke different responses from cells subjected to various cancer drugs. In particular, we show that leukemic cancer cells treated with doxorubicin and daunorubicin, commonly used anti-cancer drugs, have over 100% longer transit times through the device, compared to untreated leukemic cells. Such delays in the microcirculation are known to promote extravasation of cells, a key step in the metastatic cascade. Furthermore, we report a significant (p < 0.01) increase in the chemotactic migration of the doxorubicin treated leukemic cells. Both enhanced retention in the microcirculation and enhanced migration following chemotherapy, are pro metastatic effects which can serve as new targets for anti-metastatic drugs. PMID- 27687548 TI - NSAIDs diclofenac, indomethacin, and meloxicam highly upregulate expression of ICAM-1 and COX-2 induced by X-irradiation in human endothelial cells. AB - BACKGROUND: It is well known that radiation exposure to the heart and the use of non-steroidal anti-inflammatory drugs (NSAIDs) increase the risk of myocardial infarction (MI). Some NSAIDs are also known to act synergistically with ionizing radiation and have radio-sensitizing effects in radiotherapy. These evidences suggest that NSAIDs may affect the risk of MI after radiation exposure to the heart. In the present study, we investigated effects of NSAIDs on radiation induced expression of cell adhesion molecules and COX-2, which are associated with inflammation and an increased risk of MI, in human endothelial cells. METHODS: Effects of NSAIDs on radiation-induced expression of ICAM-1, VCAM-1, E selectin, and COX-2 were investigated in human umbilical vein endothelial cells (HUVECs). As NSAIDs, diclofenac, etodolac, indomethacin, ketoprofen, meloxicam, and rofecoxib were used. RESULTS: Irradiation with 10 Gy increased expression of ICAM-1 and COX-2, but it did not affect expression of VCAM-1 or E-selectin. All the NSAIDs upregulated radiation-induced expression of ICAM-1 and COX-2. The extent of upregulation varied depending on the types of NSAIDs. Indomethacin, diclofenac, and meloxicam highly upregulated radiation-induced expression of ICAM 1 and COX-2. The extent of upregulation was not related to the degree of COX-2 selectivity. An NF-kappaB inhibitor BAY 11-7082 suppressed radiation-induced expression of ICAM-1, but it did not suppress upregulated expression of ICAM-1 or COX-2 by combination treatment with X-irradiation and meloxicam, suggesting the existence of NF-kappaB-independent pathways for ICAM-1 and COX-2 induction. CONCLUSION: Indomethacin, diclofenac, and meloxicam highly upregulated radiation induced expression of ICAM-1 and COX-2 in HUVECs, which suggests that use of these NSAIDs may increase the effects of ionizing radiation and affect the risk of MI after radiation exposure to the heart. PMID- 27687549 TI - Mitochondrial DNA mutation m.5512A > G in the acceptor-stem of mitochondrial tRNATrp causing maternally inherited essential hypertension. AB - Essential hypertension (EH) is a common complex disorder with high heritability. Maternal inherited pattern was observed in some families with EH, which was known as maternally inherited essential hypertension (MIEH). Mitochondrial DNA (mtDNA) mutations were identified to account for some MIEH in previous studies. In the present study, we characterized clinical manifestations and the complete mitochondrial genome of a Chinese family with MIEH. Through analyzing the whole mtDNA genome of the proband, we identified a mutation m.5512A > G in the MT-TW gene that changed a highly conserved nucleotide and could potentially affect the function of tRNATrp. Furthermore, significantly exercise intolerance, left ventricular remodeling and increased arterial stiffness were observed in carriers with mutation m.5512A > G, which further supported the potentially pathogenic effect of m.5512A > G in MIEH. PMID- 27687550 TI - A-to-I RNA editing of the IGFBP7 transcript increases during aging in porcine brain tissues. AB - The IGFBP7 gene encodes insulin-like growth factor protein 7. IGFPB7 is involved in diverse biological functions including cell growth regulation, senescence and apoptosis, and also acts as a tumor suppressor in multiple cancers. The IGFBP7 mRNA is subject to A-to-I RNA editing mediated by adenosine deaminases acting on RNA 1 and 2 (ADAR1 and ADAR2). In the current study we have examined molecular characteristics of the porcine IGFBP7 gene, and determined the mRNA editing in different tissues. The A-to-I RNA editing of human IGFBP7 in positions Arg78 and Lys95 was shown to be conserved in the porcine homologue. In addition, a novel editing site was discovered in position Lys97 in the porcine IGFBP7 transcript. A differential editing was demonstrated at the three positions in the IGFBP7 transcript with very high degrees of editing in frontal cortex, cerebellum and lung. Interestingly, the degree of editing increased during aging in porcine frontal cortex and cerebellum. The IGFBP7 gene was mapped to pig chromosome 8. The porcine IGFBP7 gene was found to be ubiquitously expressed in examined organs and tissues. The methylation status of the IGFBP gene was examined in brain and liver by bisulfate sequencing and a high degree of methylation was found in the two tissues, 52% and 54%, respectively.

AB - This comment contains the reflections of a first-time participant in the 13th International Association of Bioethics Congress (IAB 2016), held from June 14 to 17, 2016, in Edinburgh. At the outset, I would like to make a couple of clarifications. First, the opinions expressed here are my personal reflections and second, I am a physician and public health practitioner by profession and my interest is bioethics. I reflect on the justice implications of the IAB 2016 from the perspective of the challenge of maintaining inclusivity in a multidisciplinary bioethics world. PMID- 27687552 TI - A computer-human interaction model to improve the diagnostic accuracy and clinical decision-making during 12-lead electrocardiogram interpretation. AB - INTRODUCTION: The 12-lead Electrocardiogram (ECG) presents a plethora of information and demands extensive knowledge and a high cognitive workload to interpret. Whilst the ECG is an important clinical tool, it is frequently incorrectly interpreted. Even expert clinicians are known to impulsively provide a diagnosis based on their first impression and often miss co-abnormalities. Given it is widely reported that there is a lack of competency in ECG interpretation, it is imperative to optimise the interpretation process. Predominantly the ECG interpretation process remains a paper based approach and whilst computer algorithms are used to assist interpreters by providing printed computerised diagnoses, there are a lack of interactive human-computer interfaces to guide and assist the interpreter. METHODS: An interactive computing system was developed to guide the decision making process of a clinician when interpreting the ECG. The system decomposes the interpretation process into a series of interactive sub-tasks and encourages the clinician to systematically interpret the ECG. We have named this model 'Interactive Progressive based Interpretation' (IPI) as the user cannot 'progress' unless they complete each sub-task. Using this model, the ECG is segmented into five parts and presented over five user interfaces (1: Rhythm interpretation, 2: Interpretation of the P-wave morphology, 3: Limb lead interpretation, 4: QRS morphology interpretation with chest lead and rhythm strip presentation and 5: Final review of 12-lead ECG). The IPI model was implemented using emerging web technologies (i.e. HTML5, CSS3, AJAX, PHP and MySQL). It was hypothesised that this system would reduce the number of interpretation errors and increase diagnostic accuracy in ECG interpreters. To test this, we compared the diagnostic accuracy of clinicians when they used the standard approach (control cohort) with clinicians who interpreted the same ECGs using the IPI approach (IPI cohort). RESULTS: For the control cohort, the (mean; standard deviation; confidence interval) of the ECG interpretation accuracy was (45.45%; SD=18.1%; CI=42.07, 48.83). The mean ECG interpretation accuracy rate for the IPI cohort was 58.85% (SD=42.4%; CI=49.12, 68.58), which indicates a positive mean difference of 13.4%. (CI=4.45, 22.35) An N-1 Chi-square test of independence indicated a 92% chance that the IPI cohort will have a higher accuracy rate. Interpreter self-rated confidence also increased between cohorts from a mean of 4.9/10 in the control cohort to 6.8/10 in the IPI cohort (p=0.06). Whilst the IPI cohort had greater diagnostic accuracy, the duration of ECG interpretation was six times longer when compared to the control cohort. CONCLUSIONS: We have developed a system that segments and presents the ECG across five graphical user interfaces. Results indicate that this approach improves diagnostic accuracy but with the expense of time, which is a valuable resource in medical practice. PMID- 27687553 TI - Efficacy and Safety of Bevacizumab Combined With Fluoropyrimidine Monotherapy for Unfit or Older Patients With Metastatic Colorectal Cancer: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Whether bevacizumab represents a feasible option for the first-line treatment of unfit and elderly patients with metastatic colorectal cancer (mCRC) remains controversial. The present systematic review and meta-analysis evaluated the efficacy and safety data of bevacizumab combined with first-line fluoropyrimidine monochemotherapy for these complex patients. PATIENTS AND METHODS: A systematic search of the published data was conducted through May 31, 2016. The random-effects model was used to combine the effect estimates and the I2 index to quantify the between-study heterogeneity unexplained by sampling error. RESULTS: We included 3 randomized controlled trials, 4 single-arm phase II trials, and 1 prospective cohort study in the present meta-analysis (n = 782). The monochemotherapy administered was capecitabine in 531 patients (67.9%) and 5 fluorouracil in 251 (32.1%); 500 (63.9%) also received bevacizumab. The median age was 75 years, 441 patients (56.4%) were men, and the Eastern Cooperative Oncology Group performance status was 0 to 1 in 684 patients (87.7%). The combination with bevacizumab produced advantages in terms of both progression free survival (hazard ratio, 0.52; 95% confidence interval, 0.43-0.64; P < .00001; I2 = 0%) and overall survival (HR, 0.79; 95% CI, 0.64-0.98; P = .03; I2 = 0%). The pooled effect estimates of the randomized controlled trials have been previously reported. As expected, all-grade hypertension (27% vs. 4.9%), bleeding (24% vs. 6.4%), thromboembolic events (10% vs. 5%), and proteinuria (25.6% vs. 8.2%) were more frequent in the bevacizumab combination group. CONCLUSION: Adding bevacizumab to first-line fluoropyrimidine monochemotherapy significantly improved progression-free and overall survival in unfit and elderly patients with mCRC, with a manageable safety profile and no unexpected toxicities.

AB - Though only one component product of the larger eugenics movement, the eugenic family study proved to be, by far, its most potent ideological tool. The Kallikak Family, for instance, went through eight editions between 1913 and 1931. This essay argues that the current scholarship has missed important ways that the architects of the eugenic family studies theorized and described the subjects of their investigation. Using one sparsely interrogated work (sociologist Frank Wilson Blackmar's "The Smoky Pilgrims") and one previously unknown eugenic family study (biologist Frank Gary Brooks' untitled analysis of the flood-zone Oklahomans) from the Southern Plains, this essay aims to introduce "environment" as a schema that allows for how the subjects of the eugenic family study were conceptualized with respect to their surroundings. Geospatially and environmentally relevant constructions of scientific knowledge were central to the project of eugenics during its formative years, but remain largely and conspicuously absent from the critical literature which engages this project to separate the fit from the unfit in American society. The dysgenic constituted a unique human geography, giving us significant insight into how concatenations of jurisprudence as well as cultural and social worth were tied to the land. PMID- 27687555 TI - Enhanced Th1 and Th17 responses in peripheral blood in active non-segmental vitiligo. AB - Accumulating studies have indicated that vitiligo, especially non-segmental vitiligo (NSV), is one kind of autoimmune diseases and CD4+ T cells play important roles in the pathogenesis. However, there have been very limited data on the detailed changes of each of the CD4+ T cell subsets in periphery in active NSV. To clarify this issue, we collected the peripheral blood mononuclear cells (PBMCs) from 30 patients with active NSV and 30 age- and sex-matched healthy controls. The percentages of circulating Th1, Th2, Th17 and Tregs were evaluated using flow cytometry and the expressions of their specific transcription factors T-bet, GATA3, RORgammat and FOXP3 at mRNA level and protein levels were qualified by qPCR and flow cytometry, respectively. Meanwhile, the expression levels of IFN gamma, IL-4, TGF-beta, and IL-17A in serum were measured. We found that in patients with NSV, the percentages and absolute numbers of circulating Th1 and Th17 were both significantly higher than those of healthy controls, while the percentages of Th2 and Tregs and absolute numbers showed no significant difference compared to healthy controls. Moreover, the ratios of Th1/Tregs and Th17/Tregs in circulation were both statistically elevated in active NSV. Similar results were got in qualification of their corresponding transcription factors at mRNA level and protein levels. Compared with healthy controls, the expression level of IL-17A was significantly increased in serum of patients with NSV, while the productions of IFN-gamma, IL-4, TGF-beta had no significant change. These data suggested that in circulating CD4+ T cell subsets, Th1 and Th17 played the major role in cellular immunity in the progression of vitiligo. The immune lever in circulation was inclined to effector CD4+ T cells not suppressor CD4+ T cells that may result in the loss of self-tolerance to melanocytes. PMID- 27687556 TI - Walking through an aperture with visual information obtained at a distance. AB - The present study addressed whether visual information about the width of an aperture, obtained at a distance, would be sufficient to guide walking through the aperture without collision. For this purpose, we asked twelve young participants to walk while holding a 66-cm horizontal bar (bar length needs to be considered in order to perceive space necessary for crossing) and pass through an aperture without vision from 3 m in front of the aperture. Participants performed the tasks under each of four visual conditions, which differed in how vision was available: observation for 1.5 s while standing (static vision), observation during two forward steps and stopping (dynamic vision), observation during two forward steps and not stopping (dynamic vision with nonstop walking), and full vision. The results showed that, for narrow apertures (the widths were 0.8 and 1.0 times the bar length), the rate of collision without vision was about 40-50 %. This was mainly due to the maladaptive planning of body rotation. For the aperture 1.0 times the bar length, the percentage of trials with no body rotation was high, suggesting that at least some participants underestimated the space necessary for crossing. The location at which maximum body rotation occurred became farther from the obstacle, which may have been related to decreased movement speed. The availability of dynamic visual sampling during two forward steps did not contribute to improving collision avoidance. These results suggest that, while fundamental locomotor patterns are maintained even without online vision, both the underestimation of space required for crossing and the lack of fine-tuning of behavior prior to crossing increased collision rates. PMID- 27687558 TI - The prefrontal oxygenation and ventilatory responses at start of one-legged cycling exercise have relation to central command. AB - When performing exercise arbitrarily, activation of central command should start before the onset of exercise, but when exercise is forced to start with cue, activation of central command should be delayed. We examined whether the in advance activation of central command influenced the ventilatory response and reflected in the prefrontal oxygenation, by comparing the responses during exercise with arbitrary and cued start. The breath-by-breath respiratory variables and the prefrontal oxygenated-hemoglobin concentration (Oxy-Hb) were measured during one-legged cycling. Minute ventilation (Ve) at the onset of arbitrary one-legged cycling was augmented to a greater extent than cued cycling, while end-tidal carbon dioxide tension (ETco2) decreased irrespective of arbitrary or cued start. Symmetric increase in the bilateral prefrontal Oxy-Hb occurred before and at the onset of arbitrary one-legged cycling, whereas such an increase was absent with cued start. The time course and magnitude of the increased prefrontal oxygenation were not influenced by the extent of subjective rating of perceived exertion and were the same as those of the prefrontal oxygenation during two-legged cycling previously reported. Mental imagery or passive performance of the one-legged cycling increased Ve and decreased ETco2 Neither intervention, however, augmented the prefrontal Oxy-Hb. The changes in ETco2 could not explain the prefrontal oxygenation response during voluntary or passive one-legged cycling. Taken together, it is likely that the in-advance activation of central command influenced the ventilatory response by enhancing minute ventilation at the onset of one-legged cycling exercise and reflected in the preexercise increase in the prefrontal oxygenation. PMID- 27687559 TI - Interstitial glucose concentrations and hypoglycemia during 2 days of caloric deficit and sustained exercise: a double-blind, placebo-controlled trial. AB - Military personnel and some athlete populations endure short-term energy deficits from reduced energy intake and/or increased energy expenditure (EE) that may degrade physical and cognitive performance due to severe hypoglycemia (<3.1 mmol/l). The extent to which energy deficits alter normoglycemia (3.9-7.8 mmol/l) in healthy individuals is not known, since prior studies measured glucose infrequently, not continuously. The purpose of this study was to characterize the glycemic response to acute, severe energy deficit compared with fully fed control condition, using continuous glucose monitoring (CGM). For 2 days during a double blind, placebo-controlled, crossover study, 23 volunteers (17 men/6 women; age: 21.3 +/- 3.0 yr; body mass index: 25 +/- 3 kg/m) increased habitual daily EE [2,300 +/- 450 kcal/day [means +/- SD)] by 1,647 +/- 345 kcal/day through prescribed exercise (~3 h/day; 40-65% peak O2 consumption), and consumed diets designed to maintain energy balance (FED) or induce 93% energy deficit (DEF). Interstitial glucose concentrations were measured continuously by CGM (Medtronic Minimed). Interstitial glucose concentrations were 1.0 +/- 0.9 mmol/l lower during DEF vs. FED (P < 0.0001). The percentage of time spent in mild (3.1-3.8 mmol/l) hypoglycemia was higher during DEF compared with FED [mean difference = 20.5%; 95% confidence interval (CI): 13.1%, 27.9%; P = 0.04], while time spent in severe (<3.1 mmol/l) hypoglycemia was not different between interventions (mean difference = 4.6%; 95% CI: -0.6%, 9.8%; P = 0.10). Three of 23 participants spontaneously reported symptoms (e.g., nausea) potentially related to hypoglycemia during DEF, and an additional participant reported symptoms during both interventions. These findings suggest that severe hypoglycemia rarely occurs in healthy individuals enduring severe, short-term energy deficit secondary to heavy exercise and inadequate energy intake. PMID- 27687560 TI - Effects of repetitive transcranial magnetic stimulation of upper airway muscles during sleep in obstructive sleep apnea patients. AB - We tested the hypothesis that stimulating the genioglossus by repetitive transcranial magnetic stimulation (rTMS) during the ascendant portion of the inspiratory flow of airflow-limited breaths would sustain the recruitment of upper airway dilator muscles over time and improve airway dynamics without arousing obstructive sleep apnea (OSA) patients. In a cross-sectional design, nine OSA patients underwent a rTMS trial during stable non-rapid eye movement (NREM) sleep. Submental muscle motor threshold (SUB) and motor-evoked potential were evaluated during wakefulness and sleep. During NREM sleep, maximal inspiratory flow, inspiratory volume, inspiratory time, shifts of electroencephalogram frequency, and pulse rate variability were assessed under three different stimulation paradigms completed at 1.2 sleep SUB stimulation output: 1) 5Hz-08 (stimulation frequency: 5 Hz; duration of train stimulation: 0.8 s); 2) 25Hz-02 (stimulation frequency: 25 Hz; duration of train stimulation: 0.2 s); and 3) 25Hz-04 (stimulation frequency: 25 Hz; duration of train stimulation: 0.4 s). SUB increased during NREM sleep (wakefulness: 23.8 +/- 6.1%; NREM: 26.8 +/- 5.2%; = 0.001). Two distinct airflow patterns were observed in response to rTMS: with and without initial airflow drops, without other airflow variables change regardless the stimulation paradigm applied. Finally, rTMS induced cortical and/or autonomic arousal were observed in 36, 26, and 35% of all delivered rTMS trains during 5Hz-08, 25Hz-02, and 25Hz-04 stimulation paradigms, respectively. In conclusion, rTMS does not provide any airflow improvement of flow-limited breaths as seen with nonrepetitive TMS of upper airway dilator muscles. However, rTMS trains were free of arousals in the majority of cases. PMID- 27687561 TI - Estimating oxygen uptake and energy expenditure during treadmill walking by neural network analysis of easy-to-obtain inputs. AB - The study of oxygen uptake (Vo2) dynamics during walking exercise transitions adds valuable information regarding fitness. However, direct Vo2 measurements are not practical for general population under realistic settings. Devices to measure Vo2 are associated with elevated cost, uncomfortable use of a mask, need of trained technicians, and impossibility of long-term data collection. The objective of this study was to predict the Vo2 dynamics from heart rate and inputs from the treadmill ergometer by a novel artificial neural network approach. To accomplish this, 10 healthy young participants performed one incremental and three moderate constant work rate treadmill walking exercises. The speed and grade used for the moderate-intensity protocol was related to 80% of the Vo2 response at the gas exchange threshold estimated during the incremental exercise. The measured Vo2 was used to train an artificial neural network to create an algorithm able to predict the Vo2 based on easy-to-obtain inputs. The dynamics of the Vo2 response during exercise transition were evaluated by exponential modeling. Within each participant, the predicted Vo2 was strongly correlated to the measured Vo2 ( = 0.97 +/- 0.0) and presented a low bias (~0.2%), enabling the characterization of the Vo2 dynamics during treadmill walking exercise. The proposed algorithm could be incorporated into smart devices and fitness equipment, making them suitable for tracking changes in aerobic fitness and physical health beyond the infrequent monitoring of patients during clinical interventions and rehabilitation programs. PMID- 27687562 TI - State-dependent and -independent effects of dialyzing excitatory neuromodulator receptor antagonists into the ventral respiratory column. AB - Unilateral dialysis of the broad-spectrum muscarinic receptor antagonist atropine (50 mM) into the ventral respiratory column [(VRC) including the pre-Botzinger complex region] of awake goats increased pulmonary ventilation (Vi) and breathing frequency (f), conceivably due to local compensatory increases in serotonin (5 HT) and substance P (SP) measured in effluent mock cerebral spinal fluid (mCSF). In contrast, unilateral dialysis of a triple cocktail of antagonists to muscarinic (atropine; 5 mM), neurokinin-1, and 5-HT receptors does not alter Vi or f, but increases local SP. Herein, we tested hypotheses that 1) local compensatory 5-HT and SP responses to 50 mM atropine dialyzed into the VRC of goats will not differ between anesthetized and awake states; and 2) bilateral dialysis of the triple cocktail of antagonists into the VRC of awake goats will not alter Vi or f, but will increase local excitatory neuromodulators. Through microtubules implanted into the VRC of goats, probes were inserted to dialyze mCSF alone (time control), 50 mM atropine, or the triple cocktail of antagonists. We found 1) equivalent increases in local 5-HT and SP with 50 mM atropine dialysis during wakefulness compared with isoflurane anesthesia, but Vi and f only increased while awake; and 2) dialyses of the triple cocktail of antagonists increased Vi, f, 5-HT, and SP (<0.05) during both day and night studies. We conclude that the mechanisms governing local neuromodulator levels are state independent, and that bilateral excitatory receptor blockade elicits an increase in breathing, presumably due to a local, (over)compensatory neuromodulator response.NEW & NOTEWORTHY The two major findings are as follows: 1) during unilateral dialysis of 50 mM atropine into the ventral respiratory column to block excitatory muscarinic receptor activity, a compensatory increase in other neuromodulators was state independent, but the ventilatory response appears to be state dependent; and 2) the hypothesis that absence of decreased Vi and f during unilateral dialysis of excitatory receptor antagonists was due to compensation by the contralateral VRC was not supported by findings herein.

PMID- 27687563 TI - Validity and reliability of measuring resting muscle sympathetic nerve activity using short sampling durations in healthy humans. AB - Resting muscle sympathetic nerve activity (MSNA) demonstrates high intraindividual reproducibility when sampled over 5-30 min epochs, although shorter sampling durations are commonly used before and during a stress to quantify sympathetic responsiveness. The purpose of the present study was to examine the intratest validity and reliability of MSNA sampled over 2 and 1 min and 30 and 15 s epoch durations. We retrospectively analyzed 68 resting fibular nerve microneurographic recordings obtained from 53 young, healthy participants (37 men; 23 +/- 6 yr of age). From a stable 7-min resting baseline, MSNA (burst frequency and incidence, normalized mean burst amplitude, total burst area) was compared among each epoch duration and a standard 5-min control. Bland-Altman plots were used to determine agreement and bias. Three sequential MSNA measurements were collected using each sampling duration to calculate absolute and relative reliability (coefficients of variation and intraclass correlation coefficients). MSNA values were similar among each sampling duration and the 5 min control (all P > 0.05), highly correlated (r = 0.69-0.93; all P < 0.001), and demonstrated no evidence of fixed bias (all P > 0.05). A consistent proportional bias (P < 0.05) was present for MSNA burst frequency (all sampling durations) and incidence (1 min and 30 and 15 s), such that participants with low and high average MSNA underestimated and overestimated the true value, respectively. Reliability decreased progressively using the 30- and 15-s sampling durations. In conclusion, short 2 and 1 min and 30 s sampling durations can provide valid and reliable measures of MSNA, although increased sample size may be required for epochs <=30 s, due to poorer reliability. PMID- 27687565 TI - A Thousand Fly Genomes: An Expanded Drosophila Genome Nexus. AB - The Drosophila Genome Nexus is a population genomic resource that provides D. melanogaster genomes from multiple sources. To facilitate comparisons across data sets, genomes are aligned using a common reference alignment pipeline which involves two rounds of mapping. Regions of residual heterozygosity, identity-by descent, and recent population admixture are annotated to enable data filtering based on the user's needs. Here, we present a significant expansion of the Drosophila Genome Nexus, which brings the current data object to a total of 1,121 wild-derived genomes. New additions include 305 previously unpublished genomes from inbred lines representing six population samples in Egypt, Ethiopia, France, and South Africa, along with another 193 genomes added from recently-published data sets. We also provide an aligned D. simulans genome to facilitate divergence comparisons. This improved resource will broaden the range of population genomic questions that can addressed from multi-population allele frequencies and haplotypes in this model species. The larger set of genomes will also enhance the discovery of functionally relevant natural variation that exists within and between populations.

AB - The anti-microbial and anti-oxidant effects of xanthones extract from Swertia macrosperma C.B. Clark were investigated using extracts from whole plant and partitioned by petroleum ether, ethyl acetate and n-butanol, respectively. Anti microbial and anti-oxidant activities were detected among different fractions. High-performance liquid chromatography was performed to separate and purify the elutions. The compounds were elucidated by 1H, 13C NMR and LCMS. The ethyl acetate extract showed maximum inhibitory activity in fungal organisms and Gram positive bacteria, and had the highest anti-oxidant capacity. Eight xanthones were isolated in ethyl acetate fraction from S. macrosperma. Moreover, compounds IV-VI and VIII were isolated from the plant for the first time, and compound VII had the strongest anti-oxidant effect. PMID- 27687567 TI - Nuf and Rip11 requirement for polarity determinant recycling during Drosophila development. AB - A tight relationship between apico-basal polarity and trafficking is essential for epithelial physiology and tissue homeostasis. Recent studies have described how some Rab GTPases, key components of the intracellular traffic machinery, contribute to the establishment of cell polarity in vertebrates. We have demonstrated a novel connection between cell polarity and trafficking: in Drosophila epithelia, the apical determinant aPKC is recycled via Rab11-Nuf recycling endosomes to maintain cell polarity. Furthermore, the phosphorylation of Nuf by aPKC allows aPKC to control the sub-cellular localization of Nuf and its own membrane accumulation. Here we review these data and show the different contribution of the 2 Drosophila Rab11 adaptor proteins, Nuf and Rip11, to the maintenance of Drosophila embryonic ectoderm polarity. PMID- 27687568 TI - Intrauterine fetal death and risk of shoulder dystocia at delivery. AB - INTRODUCTION: Vaginal delivery is recommended after intrauterine fetal death. However, little is known about the risk of shoulder dystocia in these deliveries. We studied whether intrauterine fetal death increases the risk of shoulder dystocia at delivery. MATERIAL AND METHODS: In this population-based register study using the Medical Birth Registry of Norway, we included all singleton pregnancies with vaginal delivery of offspring in cephalic presentation in Norway during the period 1967-2012 (n = 2 266 118). Risk of shoulder dystocia was estimated as absolute risk (%) and odds ratio with 95% confidence interval. Adjustment was made for offspring birthweight (in grams). We performed sub analyses within categories of birthweight (<4000 and >=4000 g) and in pregnancies with maternal diabetes. RESULTS: Shoulder dystocia occurred in 1.1% of pregnancies with intrauterine fetal death and in 0.8% of pregnancies without intrauterine fetal death (p < 0.0001) (crude odds ratio 1.5, 95% confidence interval 1.2-4.9). After adjustment for birthweight, the odds ratio was 5.9 (95% confidence interval 4.7-7.4). In pregnancies with birthweight >=4000 g, shoulder dystocia occurred in 14.6% of pregnancies with intrauterine fetal death and in 2.8% of pregnancies without intrauterine fetal death (p < 0.001) (crude odds ratio 5.9, 95% confidence interval 4.5-7.9). In pregnancies with birthweight >=4000 g and concurrent maternal diabetes, shoulder dystocia occurred in 57.1% of pregnancies with intrauterine fetal death and 9.6% of pregnancies without intrauterine fetal death (p < 0.001) (crude odds ratio 12.6, 95% confidence interval 5.9-26.9). CONCLUSIONS: Intrauterine fetal death increased the risk of shoulder dystocia at delivery, and the absolute risk of shoulder dystocia was particularly high if offspring birthweight was high and the mother had diabetes. PMID- 27687569 TI - Representing and decomposing genomic structural variants as balanced integer flows on sequence graphs. AB - BACKGROUND: The study of genomic variation has provided key insights into the functional role of mutations. Predominantly, studies have focused on single nucleotide variants (SNV), which are relatively easy to detect and can be described with rich mathematical models. However, it has been observed that genomes are highly plastic, and that whole regions can be moved, removed or duplicated in bulk. These structural variants (SV) have been shown to have significant impact on phenotype, but their study has been held back by the combinatorial complexity of the underlying models. RESULTS: We describe here a general model of structural variation that encompasses both balanced rearrangements and arbitrary copy-number variants (CNV). CONCLUSIONS: In this model, we show that the space of possible evolutionary histories that explain the structural differences between any two genomes can be sampled ergodically. PMID- 27687570 TI - Weak low-frequency electromagnetic oscillations in water. AB - Recent observations of low-frequency electromagnetic oscillations in water suggest an inductive structural component. Accordingly, we assume a helical basis enabling us to model water as an LC tuned oscillator. A proposed tetrahedral structure consisting of three water molecules and one hydronium ion is incorporated into the Boerdijk-Coxeter tetrahelix to form long water chains that are shown to have resonance frequencies consistent with observation. This model also serves to explain separately reported claims of ion cyclotron resonance of hydronium ions, in that the tetrahelix provides a built-in path for helical proton-hopping. PMID- 27687571 TI - Volitional exaggeration of body size through fundamental and formant frequency modulation in humans. AB - Several mammalian species scale their voice fundamental frequency (F0) and formant frequencies in competitive and mating contexts, reducing vocal tract and laryngeal allometry thereby exaggerating apparent body size. Although humans' rare capacity to volitionally modulate these same frequencies is thought to subserve articulated speech, the potential function of voice frequency modulation in human nonverbal communication remains largely unexplored. Here, the voices of 167 men and women from Canada, Cuba, and Poland were recorded in a baseline condition and while volitionally imitating a physically small and large body size. Modulation of F0, formant spacing (?F), and apparent vocal tract length (VTL) were measured using Praat. Our results indicate that men and women spontaneously and systemically increased VTL and decreased F0 to imitate a large body size, and reduced VTL and increased F0 to imitate small size. These voice modulations did not differ substantially across cultures, indicating potentially universal sound-size correspondences or anatomical and biomechanical constraints on voice modulation. In each culture, men generally modulated their voices (particularly formants) more than did women. This latter finding could help to explain sexual dimorphism in F0 and formants that is currently unaccounted for by sexual dimorphism in human vocal anatomy and body size.

AB - Surface-enhanced Raman scattering (SERS) substrates with high activity and stability are desirable for SERS sensing. Here, we report a new single atomic layer graphitic-C3N4 (S-g-C3N4) and Ag nanoparticles (NPs) hybrid as high performance SERS substrates. The SERS mechanism of the highly stable S-g-C3N4/Ag substrates was systematically investigated by a combination of experiments and theoretical calculations. From the results of XPS and Raman spectroscopies, it was found that there was a strong interaction between S-g-C3N4 and Ag NPs, which facilitates the uniform distribution of Ag NPs over the edges and surfaces of S-g C3N4 nanosheets, and induces a charge transfer from S-g-C3N4 to the oxidizing agent through the silver surface, ultimately protecting Ag NPs from oxidation. Based on the theoretical calculations, we found that the net surface charge of the Ag atoms on the S-g-C3N4/Ag substrates was positive and the Ag NPs presented high dispersibility, suggesting that the Ag atoms on the S-g-C3N4/Ag substrates were not likely to be oxidized, thereby ensuring the high stability of the S-g C3N4/Ag substrate. An understanding of the stability mechanism in this system can be helpful for developing other effective SERS substrates with long-term stability. PMID- 27687574 TI - Plastic microfibre ingestion by deep-sea organisms. AB - Plastic waste is a distinctive indicator of the world-wide impact of anthropogenic activities. Both macro- and micro-plastics are found in the ocean, but as yet little is known about their ultimate fate and their impact on marine ecosystems. In this study we present the first evidence that microplastics are already becoming integrated into deep-water organisms. By examining organisms that live on the deep-sea floor we show that plastic microfibres are ingested and internalised by members of at least three major phyla with different feeding mechanisms. These results demonstrate that, despite its remote location, the deep sea and its fragile habitats are already being exposed to human waste to the extent that diverse organisms are ingesting microplastics. PMID- 27687575 TI - Hormesis running hot and cold. PMID- 27687576 TI - Wideband dynamic microwave frequency identification system using a low-power ultracompact silicon photonic chip. AB - Photonic-based instantaneous frequency measurement (IFM) of unknown microwave signals offers improved flexibility and frequency range as compared with electronic solutions. However, no photonic platform has ever demonstrated the key capability to perform dynamic IFM, as required in real-world applications. In addition, all demonstrations to date employ bulky components or need high optical power for operation. Here we demonstrate an integrated photonic IFM system that can identify frequency-varying signals in a dynamic manner, without any need for fast measurement instrumentation. The system is based on a fully linear, ultracompact system based on a waveguide Bragg grating on silicon, only 65-MUm long and operating up to ~30 GHz with carrier power below 10 mW, significantly outperforming present technologies. These results open a solid path towards identification of dynamically changing signals over tens of GHz bandwidths using a practical, low-cost on-chip implementation for applications from broadband communications to biomedical, astronomy and more. PMID- 27687577 TI - Ectopic expression of Cripto-1 in transgenic mouse embryos causes hemorrhages, fatal cardiac defects and embryonic lethality. AB - Targeted disruption of Cripto-1 in mice caused embryonic lethality at E7.5, whereas we unexpectedly found that ectopic Cripto-1 expression in mouse embryos also led to embryonic lethality, which prompted us to characterize the causes and mechanisms underlying embryonic death due to ectopic Cripto-1 expression. RCLG/EIIa-Cre embryos displayed complex phenotypes between embryonic day 14.5 (E14.5) and E17.5, including fatal hemorrhages (E14.5-E15.5), embryo resorption (E14.5-E17.5), pale body surface (E14.5-E16.5) and no abnormal appearance (E14.5 E16.5). Macroscopic and histological examination revealed that ectopic expression of Cripto-1 transgene in RCLG/EIIa-Cre embryos resulted in lethal cardiac defects, as evidenced by cardiac malformations, myocardial thinning, failed assembly of striated myofibrils and lack of heartbeat. In addition, Cripto-1 transgene activation beginning after E8.5 also caused the aforementioned lethal cardiac defects in mouse embryos. Furthermore, ectopic Cripto-1 expression in embryonic hearts reduced the expression of cardiac transcription factors, which is at least partially responsible for the aforementioned lethal cardiac defects. Our results suggest that hemorrhages and cardiac abnormalities are two important lethal factors in Cripto-1 transgenic mice. Taken together, these findings are the first to demonstrate that sustained Cripto-1 transgene expression after E11.5 causes fatal hemorrhages and lethal cardiac defects, leading to embryonic death at E14.5-17.5. PMID- 27687578 TI - Early CMV-replication after allogeneic stem cell transplantation is associated with a reduced relapse risk in lymphoma. AB - A preventive effect of early human cytomegalovirus (HCMV) replication was evaluated in 136 non-Hodgkin lymphoma (NHL) patients with mature B-cell NHLs (n = 94), and mature T- and NK-cell NHLs (n = 42) after allogeneic stem cell transplantation (alloSCT). Most study-patients (85%) had received at least 2 cycles of chemotherapy and 60% had also received an autograft prior to alloSCT. First detection of CMV-replication by HCMV antigenemia/viremia was found at a median of day +33 after alloSCT. The cumulative incidence of relapse at 5 years after alloSCT was 38% (95% confidence interval [95%CI]: 26-49) in 82 patients without compared to 22% (95%CI: 8-37) in 54 patients with HCMV antigenemia/viremia (p = .013). A decreased relapse risk of HCMV replication was confirmed by multivariate analysis for HCMV antigenemia/viremia (Hazard ratio [HR]: 0.29, 95%CI: 0.11-0.76, p < .014). This report demonstrated a possible improvement of relapse incidence after replicative HCMV infection in patients with NHL after alloSCT. PMID- 27687579 TI - Variants of the elastin (ELN) gene and susceptibility to intracranial aneurysm: a synthesis of genetic association studies using a genetic model-free approach. AB - BACKGROUND: The presence of an intracranial aneurysm (IA) is thought to have a genetic origin. The genetic association studies (GAS) that investigated the association between IA and elastin gene (ELN) variants have produced contradictory or inconclusive results. MATERIALS AND METHODS: In order to decrease the uncertainty of estimated genetic risk effects, a meta-analysis of published GAS-related variants in the ELN gene (ELN INT20 1315T > C, EX20 1264G > A, INT23 1501 + 24T > C and INT4 196 + 71G > A) with susceptibility to IA was conducted using a genetic model-free approach. The risk effects were estimated using the generalized odds ratio (ORG) metric. RESULTS: The analysis showed significant association for the INT20 1315T > C variant [ORG = 0.66 (0.45-0.95)], indicating a protection effect. For the variants EX20 1264G > A, INT23 1501 + 24T > C and INT4 196 + 71G > A, no statistically significant association with IAs was found. CONCLUSION: There is evidence that the ELN variant INT20 1315T > C is implicated in the development of IA; however, the results should be interpreted with caution since the number of published studies is limited. PMID- 27687581 TI - SOD1 dimerization monitoring using a novel split NanoLuc, NanoBit. AB - In the present study, we applied a highly sensitive NanoLuc-based technology to understand the status of superoxide dismutase 1 (SOD1) within mammalian cells. Two fragments of NanoLuc (NanoBit), large N-terminal and small C-terminal regions, were fused with wild-type (wt) and mutant human SOD1 (hSOD1) genes and transfected into cells. Luciferase activity through NanoBit assembly was only detected in NanoBit-tagged wtSOD1-expressing cells. Furthermore, the developed NanoLuc system was used to investigate the role of protein-protein interactions in the pathogenesis of amyotrophic lateral sclerosis (ALS). In addition to SOD1, we also applied this NanoBit system for detecting the dimerization of wild-type, M337V-mutated human TAR-binding protein 43 kDa (hTDP43) and its cleaved C terminal fragment (TDP25M337V ) as well as their interactions with SOD1. Luciferase activities of NanoBit-tagged mutant SOD1, TDP43, or TDP25 were negligible. Finally, we found that a zinc chelator partially reduced the luciferase activity of NanoBit-wtSOD1. Collectively, these results show that the present assay is sensitive and convenient to appreciate ALS and to develop useful agents for the modulation of SOD1 conformation. PMID- 27687580 TI - Phototaxis of synthetic microswimmers in optical landscapes. AB - Many microorganisms, with phytoplankton and zooplankton as prominent examples, display phototactic behaviour, that is, the ability to perform directed motion within a light gradient. Here we experimentally demonstrate that sensing of light gradients can also be achieved in a system of synthetic photo-activated microparticles being exposed to an inhomogeneous laser field. We observe a strong orientational response of the particles because of diffusiophoretic torques, which in combination with an intensity-dependent particle motility eventually leads to phototaxis. Since the aligning torques saturate at high gradients, a strongly rectified particle motion is found even in periodic asymmetric intensity landscapes. Our results are in excellent agreement with numerical simulations of a minimal model and should similarly apply to other particle propulsion mechanisms. Because light fields can be easily adjusted in space and time, this also allows to extend our approach to dynamical environments.

AB - A lung transplant recipient was diagnosed with penicilliosis due to Talaromyces marneffei, a fungus endemic in South-East Asia, which was acquired by donor transmission. This first case of Talaromyces marneffei-transmission by transplantation underscores that current globalisation of travelling necessitates increased vigilance for transmission of unusual pathogens in organ recipients. PMID- 27687584 TI - Colloidal Nanocrystals Embedded in Macrocrystals: Methods and Applications. AB - Colloidal semiconductor nanocrystals have gained substantial interest as spectrally tunable and bright fluorophores for color conversion and enrichment solids. However, they suffer from limitations in processing their solutions as well as efficiency degradation in solid films. As a remedy, embedding them into crystalline host matrixes has stepped forward for superior photostability, thermal stability, and chemical durability while simultaneously sustaining high quantum yields. Here, we review three basic methods for loading the macrocrystals with nanocrystals, namely relatively slow direct embedding, as well as accelerated methods of vacuum-assisted and liquid-liquid diffusion-assisted crystallization. We discuss photophysical properties of the resulting composites and present their application in light-emitting diodes as well as their utilization for plasmonics and excitonics. Finally, we present a future outlook for the science and technology of these materials. PMID- 27687583 TI - Endodontic repair in immature dogs' teeth with apical periodontitis: blood clot vs plasma rich in growth factors scaffold. AB - BACKGROUND/AIM: Different types of scaffolds have been suggested for endodontic repair procedures. The aim of this study was to compare the outcome of procedures using blood clot vs plasma rich in growth factors (PRGF) scaffold in immature teeth with apical periodontitis in dogs. MATERIALS AND METHODS: In this in vivo animal study, 20 teeth (30 canals) with open apices were divided into two groups (n = 12): (1) blood clot and (2) PRGF. Two positive and negative control groups were also selected randomly. After exposing the pulp and inducing periapical inflammation by placing a sponge soaked in a suspension of dental plaque, the root canals of both groups were flushed with sodium hypochlorite and filled with triple antibiotic paste. After 28 days, the antibiotic mixture was removed, bleeding was induced through the apical foramen, and mineral trioxide aggregate was placed over the blood clot in group one and PRGF scaffold in group two. Access cavities were then filled with composite resin. The radiographic and histological findings were compared immediately after the procedure, as well as after 3 and 6 months of follow-up. RESULTS: There was no statistically significant difference between the two experimental groups with regard to the radiographic or histological results (P > 0.05). The incidence of healed periapical radiolucency was 60% and 53.33% in groups one and two, respectively. Apical closure was noted in 60% of samples in both experimental groups. New cementum-like tissue formation was detected along the walls of the canals, and bone-like islands within the canals were also observed. CONCLUSIONS: Plasma rich in growth factors scaffold showed no advantage over blood clots regarding healing of the periapical radiolucency, radiographic apical closure and type of the newly formed soft and hard tissues. PMID- 27687585 TI - Current state of genomic policies in healthcare among EU member states: results of a survey of chief medical officers. AB - Background: A need for a governance of genomics in healthcare among European Union (EU) countries arose during an international meeting of experts on public health genomics (PHG). We have conducted a survey on existing national genomic policies in healthcare among Chief Medical Officers (CMOs) of the 28 EU member states, plus Norway. Methods: A questionnaire was sent to CMOs after a meeting on the policy implications of PHG held during the Italian presidency of the Council of EU in 2014. The survey was closed in November 2015. Results: CMOs response rate was 65.5% (19/29). Twelve (63.2%) reported that their countries had a policy for genomics in healthcare in place, and 15 (78.9%) reported that public funding existed. Public research facilities for the development of such policies were documented in 13 (68.4%) countries, and 15 (83.3%) had working groups devoted to policy development. National agencies carrying out Health Technology Assessment of genomic-based technologies were present in nine countries (50%). Sixteen (88.9%) countries reported having agencies dealing with ethical issues related to genomic technologies. About 55% of countries disclosed the lack of information campaigns aimed at citizens, and 44.4% reported they had a legal framework for direct-to-consumer genetic tests. Conclusion: Belgium, France, Italy, Spain and UK documented the presence of a policy on genomics in healthcare. While many caveats are necessary because of the methodology, results suggest a need for a co ordinated effort to foster development and harmonization of dedicated policies across EU to responsibly integrate genomics policies into existing health systems. PMID- 27687587 TI - Essential and Beneficial Trace Elements in Plants, and Their Transport in Roots: a Review. AB - The essentiality of 14 mineral elements so far have been reported in plant nutrition. Eight of these elements were known as micronutrients due to their lower concentrations in plants (usually <=100 mg/kg/dw). However, it is still challenging to mention an exact number of plant micronutrients since some elements have not been strictly proposed yet either as essential or beneficial. Micronutrients participate in very diverse metabolic processes, including from the primary and secondary metabolism to the cell defense, and from the signal transduction to the gene regulation, energy metabolism, and hormone perception. Thus, the attempt to understand the molecular mechanism(s) behind their transport has great importance in terms of basic and applied plant sciences. Moreover, their deficiency or toxicity also caused serious disease symptoms in plants, even plant destruction if not treated, and many people around the world suffer from the plant-based dietary deficiencies or metal toxicities. In this sense, shedding some light on this issue, the 13 mineral elements (Fe, B, Cu, Mn, Mo, Si, Zn, Ni, Cl, Se, Na, Al, and Co), required by plants at trace amounts, has been reviewed with the primary focus on the transport proteins (transporters/channels) in plant roots. So, providing the compiled but extensive information about the structural and functional roles of micronutrient transport genes/proteins in plant roots. PMID- 27687586 TI - WNT1 Gene from WNT Signaling Pathway Is a Direct Target of miR-122 in Hepatocellular Carcinoma. AB - Hepatocellular carcinoma (HCC) is an invasive form of hepatic cancer arising from the accumulation of multiple genetic alterations. In this study, the causal role of disturbed canonical Wnt/beta-catenin pathway was approved, and some of HCC driven important gene candidates were determined. MicroRNAs (miRNAs), small non coding RNAs, are the key regulators of important cancer genes, and their participation in tumorigenesis has been shown. By reviewing literature, WNT1 gene with functional significance was selected to approve miRNAs as new subjects for targeted therapy.For proper and fast miRNA detection and also confirmation of the role of bioinformatics in obtaining practical data, we benefited from different bioinformatics tools such as TargetScan, miRanda, and DIANA. In order to use an HCC model, we used HepG2 cell line. Luciferase assay was applied to assess the ability of the selected miRNAs in targeting WNT1 3'-UTR. To overexpress the selected miRNA in HepG2 cell line, viral construct was prepared. Quantitative real-time PCR was performed to evaluate selected miRNA and target gene expression levels. miR-122 was selected according to data concerning various bioinformatics tools.miR-122 was downregulated and WNT1 gene expression was upregulated in HepG2 cell line. After viral construct transduction, miR-122 expression was elevated and WNT1 expression was notably declined. Finally, we introduced WNT1 gene as one of the important genes in HCC, and also, we showed that miR-122 can regulate WNT1 gene expression.Moreover, our study determines the potential of bioinformatics analyses in providing accurate and reliable data for miRNA: messenger RNA (mRNA) prediction. PMID- 27687588 TI - Identification and impact of discoverers in online social systems. AB - Understanding the behavior of users in online systems is of essential importance for sociology, system design, e-commerce, and beyond. Most existing models assume that individuals in diverse systems, ranging from social networks to e-commerce platforms, tend to what is already popular. We propose a statistical time-aware framework to identify the users who differ from the usual behavior by being repeatedly and persistently among the first to collect the items that later become hugely popular. Since these users effectively discover future hits, we refer them as discoverers. We use the proposed framework to demonstrate that discoverers are present in a wide range of real systems. Once identified, discoverers can be used to predict the future success of new items. We finally introduce a simple network model which reproduces the discovery patterns observed in the real data. Our results open the door to quantitative study of detailed temporal patterns in social systems. PMID- 27687589 TI - Immune adjuvant effect of a Toxoplasma gondii profilin-like protein in autologous whole-tumor-cell vaccination in mice. AB - Profilin-like protein in Toxoplasma gondii (TgPLP) is a Toll-like receptor (TLR) agonist. In this study, we investigated whether TgPLP has an adjuvant effect on immune function in autologous whole-tumor-cell vaccine (AWV) treatment. Mice vaccinated with AWV together with recombinant TgPLP protein had smaller CT26 tumors and increased survival. TgPLP treatment strongly increased the production of IL-12 through MyD88 signaling and several chemokines, including CCL5, CCL12, and XCL1, in bone marrow-derived macrophages (BMMs). In addition, TgPLP increased the phagocytosis of tumor cells by BMMs and promoted immune cell mobility on a tumor-matrigel scaffold. TgPLP triggered immune responses as demonstrated by increased expression of antigen presenting cell markers (MHC class I and II, B7.1, and B7.2) in BMMs and increased IL-12 and IFN-gamma expression in mice. Mice vaccinated with AWV and TgPLP had more immune cells (CD4+ and CD8+ T cells, natural killer cells, and macrophages) in the spleen and higher total IgG and IgG2a concentrations in the blood than mice vaccinated with AWV alone. These findings suggest that TgPLP is a TLR-based vaccine adjuvant that enhances antitumor immune responses during vaccination with AWV. PMID- 27687590 TI - Fiber-modified adenovirus-mediated suicide gene therapy can efficiently eliminate bladder cancer cells in vitro and in vivo. AB - Adenovirus-mediated gene therapy is a promising strategy for bladder cancer treatment. However, the loss of the coxsackie and adenovirus receptor (CAR) in bladder cancer cells decreases the infection efficiency of the therapeutic adenovirus. In this study, we constructed an Arg-Gly-Asp (RGD)-modified adenovirus, RGDAd-UPII-TK, that carries a suicide gene called HSV-TK that is driven by a human UPII promoter. Then, we tested the bladder cancer specificity of the UPII promotor and the expression of the HSV-TK protein. Additionally, we observed a potent cytotoxic effects of RGDAd-UPII-TK and ganciclovir (GCV) on bladder cancer as demonstrated by reduced cell survival and morphology changes in vitro. Furthermore, we confirmed that RGDAd-UPII-TK in combination with a GCV injection could significantly reduce the established T24 tumor growth and increase apoptosis in vivo. Altogether, our results indicated that the recombinant adenovirus RGDAd-UPII-TK could target bladder cancer through valid gene therapy. PMID- 27687591 TI - MDM4 rs4245739 A > C polymorphism correlates with reduced overall cancer risk in a meta-analysis of 69477 subjects. AB - Mouse double minute 4 (MDM4) is a p53-interacting oncoprotein that plays an important role in the p53 tumor suppressor pathway. The common rs4245739 A > C polymorphism creates a miR-191 binding site in the MDM4 gene transcript. Numerous studies have investigated the association between this MDM4 polymorphism and cancer risk, but have failed to reach a definitive conclusion. To address this issue, we conducted a meta-analysis by selecting eligible studies from MEDLINE, EMBASE, and Chinese Biomedical databases. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of the associations. We also performed genotype-based mRNA expression analysis using data from 270 individuals retrieved from public datasets. A total of 15 studies with 19796 cases and 49681 controls were included in the final meta-analysis. The pooled results revealed that the MDM4 rs4245739C allele is associated with a decreased cancer risk in the heterozygous (AC vs. AA: OR = 0.82, 95% CI = 0.73-0.93), dominant (AC/CC vs. AA: OR = 0.82, 95% CI = 0.72-0.93), and allele contrast models (C vs. A: OR = 0.84, 95% CI = 0.76-0.94). The association was more prominent in Asians and population based studies. We also found that the rs4245739C allele was associated with decreased MDM4 mRNA expression, especially for Caucasians. Thus the MDM4 rs4245739 A > C polymorphism appears to be associated with decreased cancer risk. These findings would be strengthened by new studies with larger sample sizes and encompassing additional ethnicities. PMID- 27687592 TI - Correlation of neuroendocrine features with prognosis of non-small cell lung cancer. AB - The improvement in histological diagnostic tools, including neuroendocrine markers by immunohistochemistry (IHC), has led to increased recognition of non small cell lung cancer (NSCLC) with neuroendocrine (NE) feature. However, little is known regarding the prevalence and clinical implications of NE feature in patients with NSCLC. In this study, we performed IHC in a tissue microarray containing 451 Chinese NSCLC cases, and analyzed correlation of the expression of neuroendocrine marker with pathological and clinical features of NSCLC. The result showed that NE feature in NSCLC was detectable in almost 30% of studied patients, and tumors with NE feature were significantly correlated with pathological classification, clinical stages and cell differentiation of NSCLC. Our data also revealed that NE feature indicated worse overall survival and disease free survival. Compared with mutant p53, NE markers showed more significance as for prognostic evaluation. Multi-factor COX analysis further suggested a potential clinical impact for NE feature as an independent indicator of poor prognosis for NSCLC patients. PMID- 27687593 TI - CARP-1 functional mimetics are novel inhibitors of drug-resistant triple negative breast cancers. AB - Doxorubicin and Cisplatin are the frontline therapeutics for treatment of the triple negative breast cancers (TNBCs). Emergence of drug-resistance often contributes to failure of drugs and poor prognosis, and thus necessitates development of new and improved modalities to treat TNBCs. We generated and characterized chemotherapy-resistant TNBC cells following their culture in chronic presence of Doxorubicin or Cisplatin, and tested whether their viabilities were inhibited by a novel class of CARP- 1 functional mimetic (CFM) compounds. Analogs of parent compound CFM-4 were obtained through structure activity based medicinal chemistry studies. CFM-4.16, a novel analog of CFM-4, caused superior inhibition of viability of TNBC cells when used in combination with doxorubicin. Doxorubicin and cisplatin inhibited viabilities of parental cells with GI50 dose of 0.02-0.1 MUM and 1.65 MUM, respectively. The GI50 dose of doxorubicin for doxorubicin-resistant TNBC cells was >= 10.0 MUM. For Cisplatin resistant cells, the GI50 dose of Cisplatin was >= 6-15.0 MUM for MDA-MB-468 sublines and >= 150.0 MUM for MDA-MB-231 sublines. CFM-4.16 inhibited viability of chemotherapy-resistant TNBC cells, in part by inhibiting oncogenic cMet activation and expression, stimulating CARP-1 expression, caspase-8 cleavage and apoptosis. CFM-4.16 pretreatment enhanced anti-TNBC efficacies of inhibitors of cMET (Tevatinib) or cSrc (Dasatinib). CFM-4.16 suppressed growth of resistant TNBC cells in soft agar as well as in three-dimensional suspension cultures derived from enriched, stem-like cells. Finally, a nanolipid formulation of CFM 4.16 in combination with doxorubicin had superior efficacy in inhibiting TNBC xenograft growth. Our findings collectively demonstrate therapeutic potential of CFM-4.16 for parental and drug-resistant TNBCs. PMID- 27687596 TI - Chest pain in the emergency room-an interesting case presentation. AB - A 61-year-old woman presented to the emergency room with atypical chest pain, non diagnostic electrocardiogram, and an initial troponin level that was normal. A coronary computed tomography angio (CCTA) was performed, and on initial review, it appeared to be normal. Subsequent review including evaluation of functional data from the retrospective scan identified a distal left anterior descending occlusion and an apical wall-motion abnormality with no other evidence of heart disease. This case illustrates the complementary contribution of anatomic and functional data and serves to remind us that on rare occasions, what looks "normal" is not always normal. PMID- 27687595 TI - Differentiation of five enterohepatic Helicobacter species by nested PCR with high-resolution melting curve analysis. AB - BACKGROUND: Enterohepatic Helicobacter species (EHS) are widespread in rodent species around the world. Several studies have demonstrated that infection with EHS can interfere with the outcomes of animal experiments in cancer research and significantly influence the study results. Therefore, it is essential to establish a rapid detection and identification of EHS for biomedical research using laboratory rodents. Our study aimed to develop a rapid and sensitive method to detect and distinguish five enterohepatic Helicobacter species. MATERIALS AND METHODS: Nested PCR followed by high-resolution melting curve analysis (HRM) was developed for identification of H. bilis, H. rodentium, H. muridarum, H. typhlonius, as well as H. hepaticus. To validate the accuracy of nested PCR-HRM analysis, quantitative real-time PCR methods for five different enterohepatic Helicobacter species were developed. A total of 50 cecal samples were tested using both nested PCR-HRM analysis and qPCR method. RESULTS: The nested PCR-HRM method could distinguish five enterohepatic Helicobacter species by different melting temperatures. The melting curve were characterized by peaks of 78.7 +/- 0.12 degrees C for H. rodentium, 80.51 +/- 0.09 degrees C for H. bilis, 81.6 +/- 0.1 degrees C for H. typhlonius, 82.11 +/- 0.18 degrees C for H. muridarum, and 82.95 +/- 0.09 degrees C for H. hepaticus. CONCLUSIONS: The nested PCR-HRM assay is a simple, rapid, and cost-effective assay. This assay could be a useful tool for molecular epidemiology study of enterohepatic Helicobacter infection and an attractive alternative for genotyping of enterohepatic Helicobacter species. PMID- 27687594 TI - Role of autophagy and lysosomal drug sequestration in acquired resistance to doxorubicin in MCF-7 cells. AB - BACKGROUND: The roles and mechanisms involved in starvation-induced autophagy in mammalian cells have been extensively studied. However, less is known about the potential role for autophagy as a survival pathway in acquired drug resistance in cancer cells under nutrient-rich conditions. METHODS: We selected MCF-7 breast tumor cells for survival in increasing concentrations of doxorubicin and assessed whether the acquisition of doxorubicin resistance was accompanied by changes in doxorubicin and lysosome localization and the activation of autophagy, as assessed by laser scanning confocal microscopy with or without immunohistochemical approaches. The ultrastructure of cells was also viewed using transmission electron microscopy. Cellular levels of autophagy and apoptosis related proteins were assessed by immunoblotting techniques, while protein turnover was quantified using a flux assay. RESULTS: As cells acquired resistance to doxorubicin, the subcellular location of the drug moved from the nucleus to the perinuclear region. The location of lysosomes and autophagosomes also changed from being equally distributed throughout the cytoplasm to co-localizing with doxorubicin in the perinuclear region. There was an apparent temporal correlation between the acquisition of doxorubicin resistance and autophagy induction, as measured by increases in monodansylcadaverine staining, LC3-II production, and co localization of LAMP1 and LC3-II immunofluorescence. Electron microscopy revealed an increase in cytoplasmic vacuoles containing mitochondria and other cellular organelles, also suggestive of autophagy. Consistent with this view, a known autophagy inhibitor (chloroquine) was highly effective in restoring doxorubicin sensitivity in doxorubicin-resistant cells. Moreover, this induction of autophagy correlated temporally with increased expression of the selective cargo receptor p62, which facilitates the delivery of doxorubicin-damaged mitochondria and other organelles to autophagosomes. Finally, we suggest that autophagy associated with doxorubicin resistance may be distinct from classical starvation-induced autophagy, since Beclin 1 and Atg7 expression did not change upon acquisition of doxorubicin resistance, nor did recombinant Bcl2 overexpression or an Atg7 knockdown alter doxorubicin cytotoxicity. CONCLUSION: Taken together, our findings suggest that doxorubicin resistance in MCF-7 breast cancer cells is mediated, at least in part, by the activation of autophagy, which may be distinct from starvation-induced autophagy. PMID- 27687597 TI - [Pulmonary hypertension: definition, classification and treatments]. AB - Pulmonary hypertension (PH) is a cardio-pulmonary disorder that may involve multiple clinical conditions and can complicate the majority of cardiovascular and respiratory diseases. Its definition is an increase in mean pulmonary artery pressure (mPAP) ?hbox{$?geqslant $} ? 25 mmHg at rest, leading to right heart failure and ultimately death. The clinical classification of pulmonary hypertension (PH) categorizes PH into groups which share similar pathophysiological and hemodynamic characteristics and treatments. Five groups of disorders that cause PH are identified: pulmonary arterial hypertension (Group 1) which is a pre-capillary PH, defined by a normal pulmonary artery wedge pressure (PAWP) ?hbox{$?leqslant $} ? 15 mmH, due to remodelling of the small pulmonary arteries (<500 MUm); pulmonary hypertension due to left heart disease (Group 2) which is a post-capillary PH, defined by an increased pulmonary artery wedge pressure (PAWP) >15 mmHg; pulmonary hypertension due to chronic lung disease and/or hypoxia (Group 3); chronic thrombo-embolic pulmonary hypertension (Group 4); and pulmonary hypertension due to unclear and/or multifactorial mechanisms (Group 5). PAH (PH group 1) can be treated with agents targeting three dysfunctional endothelial pathways of PAH: nitric oxide (NO) pathway, endothelin 1 pathway and prostacyclin pathway. Patients at low or intermediate risk can be treated with either initial monotherapy or initial oral combination therapy. In patients at high risk initial combination therapy including intravenous prostacyclin analogues should be considered. Patients with inadequate clinical response to maximum treatment (triple therapy with an intravenous prostacyclin) should be assessed for lung transplantation. Despite progresses, PAH remains a fatal disease with a 3-year survival rate of 58%. Treatment of group 2, group 3 and group 5 PH is the treatment of the causal disease and PAH therapeutics are not recommended. Treatment of group 4 PH is pulmonary endarteriectomy if patients are eligible, otherwise balloon pulmonary angioplasty and/or medical therapy can be considered. PMID- 27687598 TI - [Towards new targets for the treatment of pulmonary arterial hypertension : Importance of cell-cell communications]. AB - Pulmonary arterial hypertension (PAH) is a disorder in which mechanical obstruction of the pulmonary vascular bed is largely responsible for the rise in mean pulmonary arterial pressure (mPAP), resulting in a progressive functional decline despite current available therapeutic options. There are multiple mechanisms predisposing to and/or promoting the aberrant pulmonary vascular remodeling in PAH, and these involve not only altered crosstalk between cells within the vascular wall but also sustained inflammation and dysimmunity, cell accumulation in the vascular wall and excessive activation of some growth factor stimulated signaling pathways, in addition to the interaction of systemic hormones, local growth factors, cytokines, and transcription factors. Heterozygous germline mutations in the bone morphogenetic protein receptor, type 2 (BMPR2) gene, a gene encoding a receptor for the transforming growth factor (TGF)-beta superfamily, can predispose to the disease. Although the spectrum of therapeutic options for PAH has expanded in the last 20 years, available therapies remain essentially palliative. Over the past decade, however, a better understanding of key regulators of this irreversible remodeling of the pulmonary vasculature has been obtained. New and more effective approaches are likely to emerge. The present article profiles the innovative research into novel pathways and therapeutic targets that may lead to the development of targeted agents in PAH. PMID- 27687599 TI - [Pulmonary arterial hypertension, bone marrow, endothelial cell precursors and serotonin]. AB - Serotonin and bone-marrow-derived stem cells participate together in triggering pulmonary hypertension. Our work has shown that the absence of 5-HT2B receptors generates permanent changes in the composition of the blood and bone-marrow in the myeloid lineages, particularly in endothelial cell progenitors. The initial functions of 5-HT2B receptors in pulmonary arterial hypertension (PAH) are restricted to bone-marrow cells. They contribute to the differentiation/proliferation/mobilization of endothelial progenitor cells from the bone-marrow. Those bone-marrow-derived cells have a critical role in the development of pulmonary hypertension and pulmonary vascular remodeling. These data indicate that bone-marrow derived endothelial progenitors play a key role in the pathogenesis of PAH and suggest that interactions involving serotonin and bone morphogenic protein type 2 receptor (BMPR2) could take place at the level of the bone-marrow. PMID- 27687600 TI - [Venoms and medical research]. AB - Animal venoms are complex chemical cocktails, comprising a wide range of biologically active reticulated peptides that target with high selectivity and efficacy a variety of enzymes, membrane receptors, ion channels...Venoms can therefore be seen as large natural libraries of biologically active molecules that are continuously selected and highly refined by the evolution process, up to the point where every molecule is endowed with pharmacological properties that are highly valuable in the context of human use and drug development. Therefore, venom exploration constitutes a prerequisite to drug discovery. However, mass spectrometry and transcriptomics via NGS (Next Generation Sequencing) studies have shown the presence of up to 1000 peptides in the venom of single species of cone snails and spiders. Therefore the global animal venom resource can be seen as a collection of more than 50 to 100 000 000 peptides and proteins of which only ~5000 are known. That extraordinary "Eldorado" of bio-optimized compounds justifies the development of more global and cutting-edge strategies and technologies to explore this resource more efficiently than actually. De novo developed approaches and recently obtained results will be described. PMID- 27687601 TI - [Amphibian skin as a source of therapeutic peptides]. AB - The search for new bioactive molecules that could be used in therapeutics is a major public health issue, particularly in the treatment of certain diseases such as cancer. In this context the exploration of the venom of animals (snakes, amphibians, cones, scorpions, insects...) that produce molecules of various structures and biological activities, is a very promising direction. Research in this area led to the discovery of neuropeptides, hormones, toxins, antimicrobial peptides and other extremely potent mediators. These are now used in many areas both in fundamental research and in translational research, respectively, to understand biochemical and physiological mechanisms, or to use as medical diagnostic tools and for therapeutic purposes. Pr. V. Erspamer is the first researcher to have shown, in the 1930s, that in addition to biogenic amines and alkaloids, granular glands from the skin of amphibians also produced huge amounts of peptides with various structures and biological activities. He also showed that these peptides had their counterparts, most often in the form of identical or similar peptides, in the central nervous system and the gastrointestinal tract of mammals. These observations are summarized in the form of a triangle concept of "brain-gut-skin" that states that any peptide found in a compartment should be present in the other two. In addition, abundance, ease of extraction and identification of peptides from amphibian skin make this model a means to search for their counterparts in mammals where they are present in minute quantities. This approach has two advantages: (i) at the fundamental level, the large peptide diversity, ubiquity and multiplicity of functions to which they participate, constitute a true chemical library to understand the mechanisms of recognition and signal transduction and study the physicochemical basic of the specificity; and (ii) in terms of applications, the relative simplicity of these peptides and the rise of the production techniques by chemical or recombinant synthesis offer an innovative potential for the development of molecules with pharmacological or therapeutic purposes. PMID- 27687602 TI - [Ants: a chemical library of anticancer molecules]. AB - Animal venoms are complex mixtures containing simple organic molecules, proteins, peptides, and other bioactive elements with extraordinary biological properties associated with their ability to act on a number of molecular receptors in the process of incapacitating their target organisms. In such a context, arthropod venoms are invaluable sources of bioactive substances, with therapeutic interest but the limited availability of some venom such as those from ants, has restricted the potential that these biomolecules could represent. We investigated for the first time transcriptomic expression from the ant species Tetramorium bicarinatum. Four hundred randomly selected clones from cDNA libraries were sequenced and a total of 374 expressed sequence tags (ESTs) were generated. Based on the results of BLAST searches, these sequences were clustered and assembled into 269 contigs. About 72% (269) of these matched BLASTx hits with an interesting diversity and unusual abundance of cellular transcripts (48%) related to gene and protein expression reflecting the specialization of this tissue. In addition, transcripts encoding transposases were relatively highly expressed (14%). It may be that transposable elements are present and that their presence accounts for some of the variation in venom toxins. About twenty per cent of the ESTs were categorized as putative toxins, the major part represented by allergens (48% of the total venom toxins) such as pilosulin 5, sol i 3 and Myp p I and II. Several contigs encoding enzymes, including zinc-metalloproteases (17%) that are likely involved in the processing and activation of venom proteins/peptides, were also identified from the library. In addition, a number of sequences (8%) had no significant similarity to any known sequence which indicates a potential source of for the discovery of new toxins. In order to provide a global insight on the transcripts expressed in the venom gland of the Brazilian ant species Tetramorium bicarinatum and to unveil the potential of their products, high-throughput expressed sequence tags were generated using Illumina paired-end sequencing technology. A total of 212 371 758 pairs of quality-filtered, 100-base-pair Illumina reads were obtained. The de novo assemblies yielded 36 042 contigs for which 27 873 have at least one predicted ORF among which 59.77% produce significant hits in the available databases. The investigation of the read mapping toxin class revealed and confirmed a high diversification with the major part consistent with the classical hymenopteran venom protein signature represented by venom allergen (33.3%) followed by a diverse toxin-expression profile including several distinct isoforms of phospholipase A1 and A2, venom serine protease, hyaluronidase, protease inhibitor and secapin. Moreover, our results revealed for the first time the presence of toxin-like peptides that have been previously identified from unrelated venomous animals such as waprin-like (snakes) and agatoxins (spiders and conus). These studies provide a first insight of the gene expression scenario of the venom gland of T. bicarinatum which might contribute to acquiring a more comprehensive view about the origin and functional diversity of venom proteins of this ant. Based on such results, we conducted cytotoxic tests from the crude venom of T.bicarinatum ant and reported toxic effect on tumoral cells lines from one of the fifth of the most frequently occurring cancers with a 3-year survival rate of only 30%. In such a context, new therapeutic strategies are essential and the discovery of new molecules in ant venom could be one possible avenue. Thus our project aims to characterize, from the crude venom of T.bicarinatum, the molecule(s) which have potential anti cancerous toxicity as well as their mechanisms of action. PMID- 27687603 TI - Endothelial Cells Require CD98 for Efficient Angiogenesis-Brief Report. AB - OBJECTIVE: CD98 regulates integrin signaling and is critical for tumor cell proliferation. It is also expressed on endothelial cells (EC), but its role in angiogenesis is unclear. APPROACH AND RESULTS: We used specific genetic targeting and antibody blockade approaches to examine the function of CD98 in EC proliferation, blood vessel growth, and tumor angiogenesis. It is upregulated on angiogenic ECs, and EC-specific deletion of CD98 in mice inhibited tumor growth, retinal angiogenesis, and EC proliferation. Reconstitution with CD98 mutants showed that integrin and CD98 interaction is necessary for EC survival and growth. Moreover, anti-CD98 treatment inhibited vessel formation and reversed EC assisted tumor growth. CONCLUSIONS: Our findings demonstrate a requirement for CD98 in EC growth and suggest that CD98-specific reagents could have a dual anticancer effect: directly by inhibiting tumor cell proliferation and indirectly by preventing tumor angiogenesis. PMID- 27687606 TI - Monitoring stress among internal medicine residents: an experience-driven, practical and short measure. AB - Residents experience severely high levels of stress, depression and burnout, leading to perceived medical errors, as well as to symptoms of impairment, such as chronic anger, cognitive impairment, suicidal behavior and substance abuse. Because research has not yet provided a psychometrically robust population specific tool to measure the level of stress of medicine residents, we aimed at building and validating such a measure. Using an inductive scale development approach, a short, pragmatic measure was built, based on the interviews of 17 medicine residents. The Internal Medicine Residency Stress Scale (IMRSS) was then administered in a sample of 259 internal medicine residents (199 females, 60 males, MAge = 25.6) along with the Hospital Anxiety and Depression Scale, Maslach Burnout Inventory, Satisfaction With Life Scale and Ways of Coping Checklist. The IMRSS showed satisfactory internal reliability (Cronbach's alpha = .86), adequate structural validity - studied through Confirmatory Factor Analysis (chi2/df = 2.51, CFI = .94; SRMR = .037, RMSEA = .076) - and good criterion validity - the IMRSS was notably strongly correlated with emotional exhaustion (r = .64; p < .001) and anxiety (r = .57; p < .001). Because of its short length and robust psychometric qualities, the use of the IMRSS is recommended to quickly and frequently assess and monitor stress among internal medicine residents. PMID- 27687604 TI - Is High-Density Lipoprotein Cholesterol Causally Related to Kidney Function? Evidence From Genetic Epidemiological Studies. AB - OBJECTIVE: A recent observational study with almost 2 million men reported an association between low high-density lipoprotein (HDL) cholesterol and worse kidney function. The causality of this association would be strongly supported if genetic variants associated with HDL cholesterol were also associated with kidney function. APPROACH AND RESULTS: We used 68 genetic variants (single-nucleotide polymorphisms [SNPs]) associated with HDL cholesterol in genome-wide association studies including >188 000 subjects and tested their association with estimated glomerular filtration rate (eGFR) using summary statistics from another genome wide association studies meta-analysis of kidney function including <=133 413 subjects. Fourteen of the 68 SNPs (21%) had a P value <0.05 compared with the 5% expected by chance (Binomial test P=5.8*10-6). After Bonferroni correction, 6 SNPs were still significantly associated with eGFR. The genetic variants with the strongest associations with HDL cholesterol concentrations were not the same as those with the strongest association with kidney function and vice versa. An evaluation of pleiotropy indicated that the effects of the HDL-associated SNPs on eGFR were not mediated by HDL cholesterol. In addition, we performed a Mendelian randomization analysis. This analysis revealed a positive but nonsignificant causal effect of HDL cholesterol-increasing variants on eGFR. CONCLUSIONS: In summary, our findings indicate that HDL cholesterol does not causally influence eGFR and propose pleiotropic effects on eGFR for some HDL cholesterol-associated SNPs. This may cause the observed association by mechanisms other than the mere HDL cholesterol concentration.

PMID- 27687605 TI - Local Matrix Metalloproteinase 9 Level Determines Early Clinical Presentation of ST-Segment-Elevation Myocardial Infarction. AB - OBJECTIVE: Early clinical presentation of ST-segment-elevation myocardial infarction (STEMI) and non-ST-segment-elevation myocardial infarction affects patient management. Although local inflammatory activities are involved in the onset of MI, little is known about their impact on early clinical presentation. This study aimed to investigate whether local inflammatory activities affect early clinical presentation. APPROACH AND RESULTS: This study comprised 94 and 17 patients with MI (STEMI, 69; non-STEMI, 25) and stable angina pectoris, respectively. We simultaneously investigated the culprit lesion morphologies using optical coherence tomography and inflammatory activities assessed by shedding matrix metalloproteinase 9 (MMP-9) and myeloperoxidase into the coronary circulation before and after stenting. Prevalence of plaque rupture, thin-cap fibroatheroma, and lipid arc or macrophage count was higher in patients with STEMI and non-STEMI than in those with stable angina pectoris. Red thrombus was frequently observed in STEMI compared with others. Local MMP-9 levels were significantly higher than systemic levels (systemic, 42.0 [27.9-73.2] ng/mL versus prestent local, 69.1 [32.2-152.3] ng/mL versus poststent local, 68.0 [35.6 133.3] ng/mL; P<0.01). Poststent local MMP-9 level was significantly elevated in patients with STEMI (STEMI, 109.9 [54.5-197.8] ng/mL versus non-STEMI: 52.9 [33.0 79.5] ng/mL; stable angina pectoris, 28.3 [14.2-40.0] ng/mL; P<0.01), whereas no difference was observed in the myeloperoxidase level. Poststent local MMP-9 and the presence of red thrombus are the independent determinants for STEMI in multivariate analysis. CONCLUSIONS: Local MMP-9 level could determine the early clinical presentation in patients with MI. Local inflammatory activity for atherosclerosis needs increased attention. PMID- 27687607 TI - The Identification and Quantification of Suberin Monomers of Root and Tuber Periderm from Potato (Solanum tuberosum) as Fatty Acyl tert-Butyldimethylsilyl Derivatives. AB - INTRODUCTION: Protective plant lipophilic barriers such as suberin and cutin, with their associated waxes, are complex fatty acyl derived polyesters. Their precise chemical composition is valuable to understand the specific role of each compound to the physiological function of the barrier. OBJECTIVES: To develop a method for the compositional analysis of suberin and associated waxes by gas chromatography (GC) coupled to ion trap-mass spectrometry (IT-MS) using N-(tert butyldimethylsilyl)-N-methyl-trifluoroacetamide (MTBSTFA) as sylilating reagent, and apply it to compare the suberin of the root and tuber periderm of potato (Solanum tuberosum). METHODOLOGY: Waxes and suberin monomers from root and periderm were extracted subsequently using organic solvents and by methanolysis, and subjected to MTBSTFA derivatisation. GC analyses of periderm extracts were used to optimise the chromatographic method and the compound identification. Quantitative data was obtained using external calibration curves. The method was fully validated and applied for suberin composition analyses of roots and periderm. RESULTS: Wax and suberin compounds were successfully separated and compound identification was based on the specific (M-57) and non-specific ions in mass spectra. The use of calibration curves built with different external standards provided quantitative accurate data and showed that suberin from root contains shorter chained fatty acyl derivatives and a relative predominance of alpha,omega-alkanedioic acids compared to that of the periderm. CONCLUSION: We present a method for the analysis of suberin and their associated waxes based on MTBSTFA derivatisation. Moreover, the characteristic root suberin composition may be the adaptive response to its specific regulation of permeability to water and gases. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27687609 TI - Maltitol inhibits small intestinal glucose absorption and increases insulin mediated muscle glucose uptake ex vivo but not in normal and type 2 diabetic rats. AB - This study investigated the effects of maltitol on intestinal glucose absorption and muscle glucose uptake using ex vivo and in vivo experimental models. The ex vivo experiment was conducted in isolated jejunum and psoas muscle from normal rats. The in vivo study investigated the effects of a single bolus dose of maltitol on gastric emptying, intestinal glucose absorption and digesta transit in normal and type 2 diabetic rats. Maltitol inhibited glucose absorption in isolated rat jejunum and increased glucose uptake in isolated rat psoas muscle in the presence of insulin but not in the absence of insulin. In contrast, maltitol did not significantly (p > 0.05) alter small intestinal glucose absorption or blood glucose levels as well as gastric emptying and digesta transit in normal or type 2 diabetic rats. The results suggest that maltitol may not be a suitable dietary supplement for anti-diabetic food and food products to improve glycemic control. PMID- 27687610 TI - Engineering Halomonas spp. as A Low-Cost Production Host for Production of Bio surfactant Protein PhaP. AB - Halomonas spp. have been studied as a low cost production host for producing bulk materials such as polyhydroxyalkanoates (PHA) bioplastics, since they are able to grow at high pH and high NaCl concentration under unsterile and continuous conditions without microbial contamination. In this paper, Halomonas strain TD is used as a host to produce a protein named PHA phasin or PhaP which has a potential to be developed into a bio-surfactant. Four Halomonas TD expression strains are constructed based on a strong T7-family expression system. Of these, the strain with phaC deletion and chromosomal expression system resulted in the highest production of PhaP in soluble form, reaching 19% of total cellular soluble proteins and with a yield of 1.86 g/L in an open fed-batch fermentation process. A simple "heat lysis and salt precipitation" method is applied to allow rapid PhaP purification from a mixture of cellular proteins with a PhaP recovery rate of 63%. It clearly demonstrated that Halomonas TD could be used for high yield expression of a bio-surfactant protein PhaP for industrial application in an economical way. PMID- 27687612 TI - Assessing developmental delay in early childhood - concerns with the Bayley-III scales. AB - OBJECTIVE: Early detection of children with developmental delay is crucial for determining which children require close surveillance and intervention services. For many decades, the Bayley Scales has been the most widely used objective measure of early developmental delay, both in clinical and research settings. Significant structural changes were incorporated in the most recent edition, the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III). This article reviews the psychometric properties of the Bayley-III and investigates criticisms raised on the Bayley-III, namely that it overestimates developmental status and is a poor predictor of later functioning. METHOD: This critical review examines the literature on the Bayley-III, which was released in 2006. RESULTS: The Cognitive, Language, and Motor composites of the Bayley-III overestimate development, resulting in an under-identification of children with developmental delay. A range of strategies have been proposed for dealing with the inflated scores on the Bayley-III, none of which are ideal. Evidence to date suggests that the Bayley-III is a poor predictor of later cognitive and motor impairments. CONCLUSIONS: The Bayley-III needs new norms, or alternatively, it may be time for a new edition of the Bayley Scales. PMID- 27687611 TI - A synthesis of recent analyses of human resources for health requirements and labour market dynamics in high-income OECD countries. AB - BACKGROUND: Recognition of the importance of effective human resources for health (HRH) planning is evident in efforts by the World Health Organization (WHO) and the Global Health Workforce Alliance (GHWA) to facilitate, with partner organizations, the development of a global HRH strategy for the period 2016-2030. As part of efforts to inform the development of this strategy, the aims of this study, the first of a pair, were (a) to conduct a rapid review of recent analyses of HRH requirements and labour market dynamics in high-income countries who are members of the Organisation for Economic Co-operation and Development (OECD) and (b) to identify a methodology to determine future HRH requirements for these countries. METHODS: A systematic search of peer-reviewed literature, targeted website searches, and multi-stage reference mining were conducted. To supplement these efforts, an international Advisory Group provided additional potentially relevant documents. All documents were assessed against predefined inclusion criteria and reviewed using a standardized data extraction tool. RESULTS: In total, 224 documents were included in the review. The HRH supply in the included countries is generally expected to grow, but it is not clear whether that growth will be adequate to meet health care system objectives in the future. Several recurring themes regarding factors of importance in HRH planning were evident across the documents reviewed, such as aging populations and health workforces as well as changes in disease patterns, models of care delivery, scopes of practice, and technologies in health care. However, the most common HRH planning approaches found through the review do not account for most of these factors. CONCLUSIONS: The current evidence base on HRH labour markets in high-income OECD countries, although large and growing, does not provide a clear picture of the expected future HRH situation in these countries. Rather than HRH planning methods and analyses being guided by explicit HRH policy questions, most of the reviewed studies appeared to derive HRH policy questions based on predetermined planning methods. Informed by the findings of this review, a methodology to estimate future HRH requirements for these countries is described. PMID- 27687613 TI - BMI independently relates to glycaemia in patients with severe enduring mental illness (SMI). AB - BACKGROUND: People with severe mental illness (SMI) have higher rates of diabetes than the general population. AIMS: To assess the type-2 diabetes screening rates in primary care and the relation between body mass index (BMI) and dysglycaemia for patients on the SMI register in the Cheshire region of the United Kingdom. METHODS: The setting was 24 general practices in Central and Eastern Cheshire, United Kingdom. Subjects were identified through a semianonymized search of GP registers. RESULTS: About 451 of the 787 SMI patients were screened for dysglycaemia and dyslipidaemia. Fasting glucose was in the impaired fasting glycaemia range (6.1-6.9 mmol/l) in 6.5%, and indicative of type-2 diabetes (>=7.0 mmol/l) in 17.3%. There was a positive univariate relation between BMI and fasting glucose (normalized beta = 0.26, p < 0.001). In multivariate models, adjusting for age, gender, smoking and blood pressure, each unit increase in BMI [OR = 1.07 (1.01, 1.13); p = 0.031] and triglycerides [OR = 1.28 (1.06, 1.55); p = 0.009] were independently associated with an increased risk of having type-2 diabetes. CONCLUSION: Increasing BMI relates to dysglycaemia in patients with severe enduring mental illness (SMI). All patients with SMI whether or not receiving neuroleptic treatment should undergo routine monitoring of weight and metabolic parameters. PMID- 27687614 TI - Patient-reported long-term outcome after primary hypospadias repair. AB - PURPOSE: Long-term evaluation of the surgical outcome after puberty, particularly patient reported outcome is rare in the literature. The aims of this study were to investigation the patients' satisfaction with the long-term results and their views and memories of their childhood surgery and follow-up. METHODS: A modified version of previously used questionnaire was sent to 134 patients ages 18 years or older previously primarily repaired due to hypospadias by one of the authors (HS) between 1989 -2009. RESULTS: Thirty-nine patients responded. Eighty-two per cent were satisfied with the appearance of their penis, 87% were satisfied with their ability to urinate and their sexual function and 92% were satisfied with the overall surgical results. Ninety per cent of patients were positive to the current duration of our post-pubertal follow-up program or would have preferred an even longer follow-up. CONCLUSIONS: The majority of patients were satisfied with the long-term surgical results and the duration of follow-up. Despite having problems patients does not always contact the health care system spontaneously, which warrants long-term follow-up.

AB - PURPOSE: We evaluated the rate of hyperlipidemia identified during workplace screening in previously undiagnosed individuals, the association between workplace hyperlipidemia screening and use of medical care during follow-up, and changes in lipid profile among individuals with hyperlipidemia at screening. DESIGN: Nonexperimental longitudinal study. SETTING: Employees who participated in a workplace health screening. PARTICIPANTS: A total of 18 993 individuals from 39 self-insured employers in the United States. MEASURES: Total cholesterol, low density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides were measured during screening. A claims-based algorithm was used to identify hyperlipidemia cases. ANALYSIS: Discrete-time survival analysis was used to estimate monthly rates of new hyperlipidemia diagnoses or prescriptions. Paired t tests were used to evaluate 1-year changes in lipid profile. RESULTS: A total of 1872 (9.9%) individuals had hyperlipidemia at screening. Among all individuals, a significantly greater rate of new hyperlipidemia diagnoses was observed during the first month after screening, compared to the 3 months before screening (odds ratio [95% CI]: 2.99 [2.66-3.36]). Among the 987 individuals who were followed up 1 year later, significant improvements were observed in total cholesterol (-8.5% +/- 13.6%) and LDL levels (-10.2% +/- 19.3%). CONCLUSION: Workplace health screenings in an insured population were associated with a subsequent increase in physician visits and prescriptions for hyperlipidemia. After 1 year, significant improvements in total cholesterol and LDL levels were observed among individuals who screened positive for hyperlipidemia. PMID- 27687616 TI - Why Has the Health-Promoting Prison Concept Failed to Translate to the United States? AB - Two decades since the World Health Organization Regional Office for Europe published a report on health promotion in prison that stimulated further debate on the concept of the "health-promoting prison," this article discusses the extent to which the concept has translated to the United States. One predicted indicator of success for the health-promoting prison movement was the expansion of activity beyond European borders; yet 2 decades since the European model was put forward, there has been very limited activity in the United States. This "Critical Issues and Trends" article suggests reasons why this translation has failed to occur. PMID- 27687617 TI - An Empirical Analysis of the Association Between Cigarette Smoking and Participation in the Supplemental Nutrition Assistance Program. AB - PURPOSE: To examine the association between smoking and participation in Supplemental Nutrition Assistance Program (SNAP) among low-income families. DESIGN: A quasi-experimental design using pooled cross-sectional data from the Bureau of Labor Statistics' Consumer Expenditure Diary Survey. SETTING: A national, representative sample of US households from 2005 through 2012. PARTICIPANTS: A total of 19 395 low-income households. MEASURES: US poverty thresholds were used, in conjunction with household income, to create a sample of families at 130% of the federal poverty level and below. Expenditures on cigarettes and self-reported enrollment in SNAP were used to measure smoking behavior and program participation, respectively. ANALYSIS: Estimation of a maximum likelihood model was used to predict the probability of smoking given participation in SNAP. RESULTS: The SNAP participation among low-income households was associated with a 30% ( P < .01) increase in the likelihood of a household containing at least 1 smoker, relative to low-income non-SNAP households. Among smokers, SNAP households do not spend more money on tobacco products than non-SNAP households. CONCLUSION: Given the strong association found between SNAP participation and smoking, connecting program participants who smoke to effective smoking cessation programs could be an effective tool in reducing the prevalence of smoking among the low-income population. States have a unique opportunity to use SNAP-Education programs to integrate tobacco prevention and cessation into curriculum for direct client impact. PMID- 27687618 TI - A Pilot Study of Healthy Living Options at 16 Truck Stops Across the United States. AB - PURPOSE: There is a growing body of evidence that the built environment influences diet and exercise and, as a consequence, community health status. Since long-haul truck drivers spend long periods of time at truck stops, it is important to know if this built environment includes resources that contribute to the emotional and physical well-being of drivers. SETTING: The truck stop environment was defined as the truck stop itself, grocery stores, and medical clinics near the truck stop that could be accessed by a large truck or safely on foot. DESIGN: Researchers at the National Institute for Occupational Safety and Health (NIOSH) developed and utilized a checklist to record the availability of resources for personal hygiene and comfort, communication and mental stimulation, health care, safety, physical activity, and nutrition at truck stops. SUBJECTS: The NIOSH checklist was used to collect data at a convenience sample of 16 truck stops throughout the United States along both high-flow and low-flow truck traffic routes. MEASURES: The checklist was completed by observation within and around the truck stops. RESULTS: No truck stops offered exercise facilities, 94% lacked access to health care, 81% lacked a walking path, 50% lacked fresh fruit, and 37% lacked fresh vegetables in their restaurant or convenience store. CONCLUSION: The NIOSH found that most truck stops did not provide an overall healthy living environment. PMID- 27687619 TI - Comparing State Legislative Aides' Perspectives on Tobacco Policymaking in States With Strong and Weak Policies: A Qualitative Study. AB - PURPOSE: The study compared perceptions of state legislative aides about tobacco policymaking in states with strong and weak tobacco control policies. APPROACH: Qualitative in-depth interviews carried out in 2009. SETTING: The US states were ranked on a combination of tobacco prevention funding, taxes, and presence of smoke-free policies. States at the top and bottom of the rankings were chosen. PARTICIPANTS: Interviews were conducted with 10 legislative aides in 5 states with strong tobacco control policies and 10 aides in 7 states with weak policies. METHOD: Twenty semistructured interviews were conducted, coded, and analyzed using a consensus coding process. RESULTS: Tobacco control was a lower priority in states with weak policies, and respondents from these states listed more barriers to tobacco control policymaking than those from states with strong policies. Successful arguments for tobacco control emphasized operational applications, for example, enhanced revenue from tobacco taxes or safety of children and employees. CONCLUSION: Our findings support propositions posited in the Advocacy Coalition Framework. They point to the preeminence of contextual factors, notably political leanings and economic climate on success of policy change efforts. Lessons learned from participants from states with strong policy nonetheless show promise for success in states with weak policy. PMID- 27687620 TI - Assessment of dietary intake of children with chronic kidney disease. AB - OBJECTIVE: Our aim was to characterize the nutrient intake of children with chronic kidney disease (CKD) relative to recommended intake levels. METHODS: We conducted a cross-sectional study of dietary intake assessed by Food Frequency Questionnaire (FFQ) in The North American Chronic Kidney Disease in Children (CKiD) prospective cohort study. Nutrient intake was analyzed to estimate the daily consumption levels of various nutrients and compared with national guidelines for intake. RESULTS: There were 658 FFQs available for analysis; 69.9 % of respondents were boys, with a median age [Interquartile range (IQR)] of 11 years (8-15). Median daily sodium, potassium, and phosphorus intake was 3089 mg (2294-4243), 2384 mg (1804-3076), and 1206 mg (894-1612) respectively. Sodium and phosphorus consumptions were higher than recommended in all age groups. Caloric intake decreased with dropping glomerular filtration rate (GFR) (p = 0.003). The median daily caloric intakes were 1307 kcal in male children 2-3 years old, 1875 kcal in children 4-8 years old, 1923 kcal in those 9-13 years old, and 2427 kcal in those 14-18 years old. Respective levels for girls were 1467 kcal, 1736 kcal, 1803 kcal, and 2281 kcal. Median protein intake exceeded recommended levels in all age groups, particularly among younger participants. Younger children were more likely than older children to exceed the recommended intakes for phosphorus (p < 0.001) and the age-specific recommended caloric intake (p < 0.001). Macronutrient distribution (carbohydrate:fat:protein) was consistent with recommendation. CONCLUSIONS: Children in the CKiD cohort consumed more sodium, phosphorus, protein, and calories than recommended. The gap between actual consumption and recommendations indicates a need for improved nutritional counseling and monitoring. PMID- 27687621 TI - Ofatumumab in two pediatric nephrotic syndrome patients allergic to rituximab. AB - BACKGROUND: Rituximab, a chimeric anti-CD20 monoclonal antibody, is an effective treatment in steroid-dependent nephrotic syndrome (SDNS). However, some patients develop adverse reactions. CASE-DIAGNOSIS/TREATMENT: Patient 1, a 14-year-old boy with SDNS since the age of 2, was treated with oral prednisone, cyclosporine A (CsA) and mycophenolate mofetil. A first infusion of rituximab at age 12 years was well tolerated, but this was followed by a prolonged relapse unresponsive to oral prednisone, mycophenolate mofetil and CsA. A second rituximab infusion was attempted, but treatment was interrupted due to severe dyspnea. Treatment with a humanized anti-CD20 monoclonal antibody, ofatumumab, was then attempted. The patient experienced a mild allergic reaction and maintained remission despite interruption of all treatment at >12 months of follow-up. Patient 2, a 3-year-old boy who presented at 18 months with nephrotic syndrome initially resistant to treatment with oral prednisone, was given with three intravenous boluses of methylprednisolone followed by CsA and achieved remission. Upon steroid discontinuation, the NS relapsed. Prednisone was restarted and treatment with a single dose of rituximab was never completed due to a severe allergic reaction. Ofatumumab infusion was uneventful, and he maintained remission during the follow up period (>12 months) despite interruption of prednisone therapy. B cells reappeared at 7 months in both patients. CONCLUSIONS: Ofatumumab may be a therapeutic option in severe forms of NS with allergy to rituximab. PMID- 27687623 TI - Preoperative 6-minute walk distance accurately predicts postoperative complications after operations for hepato-pancreato-biliary cancer. AB - BACKGROUND: Operation for hepato-pancreato-biliary cancer is among the most invasive open abdominal operations, with a high postoperative morbidity and mortality rate. The purpose of the present study is to investigate whether a preoperative 6-minute walk distance can predict major postoperative complications after operation for hepato-pancreato-biliary diseases. METHODS: A total of 81 participants who underwent pancreaticoduodenectomy, major hepatectomy with extrahepatic bile duct resection, or hepatopancreatoduodenectomy were included. The 6-minute walk distance was performed within 1 week before operation. Patients were categorized into 2 groups based on surgical complications: Clavien-Dindo grade <3 and Clavien-Dindo grade >=3. Clinical differences between the 2 groups were analyzed. Multivariate logistic regression analysis was performed to identify risk factors for postoperative complications that were categorized as Clavien-Dindo grade >=3. RESULTS: The multiple logistic regression model revealed a significant correlation between major postoperative complications and preoperative low 6-minute walk distance, low body mass index, and major blood loss. In patients with 6-minute walk distance <400 m (1,312 feet), the Clavien Dindo grade was considerably greater than patients with >=400 m. CONCLUSION: The 6-minute walk distance is useful in identifying patients with a greater chance of developing major postoperative complications after surgery for hepato-pancreato biliary cancer. PMID- 27687622 TI - Statin derivatives as therapeutic agents for castration-resistant prostate cancer. AB - Despite recent advances in modern medicine, castration-resistant prostate cancer remains an incurable disease. Subpopulations of prostate cancer cells develop castration-resistance by obtaining the complete steroidogenic ability to synthesize androgens from cholesterol. Statin derivatives, such as simvastatin, inhibit cholesterol biosynthesis and may reduce prostate cancer incidence as well as progression to advanced, metastatic phenotype. In this study, we demonstrate novel simvastatin-related molecules SVA, AM1, and AM2 suppress the tumorigenicity of prostate cancer cell lines including androgen receptor-positive LNCaP C-81 and VCaP as well as androgen receptor-negative PC-3 and DU145. This is achieved through inhibition of cell proliferation, colony formation, and migration as well as induction of S-phase cell-cycle arrest and apoptosis. While the compounds effectively block androgen receptor signaling, their mechanism of inhibition also includes suppression of the AKT pathway, in part, through disruption of the plasma membrane. SVA also possess an added effect on cell growth inhibition when combined with docetaxel. In summary, of the compounds studied, SVA is the most potent inhibitor of prostate cancer cell tumorigenicity, demonstrating its potential as a promising therapeutic agent for castration-resistant prostate cancer. PMID- 27687625 TI - Introduction to the Special Section. PMID- 27687624 TI - Reproducibility of locus coeruleus and substantia nigra imaging with neuromelanin sensitive MRI. AB - OBJECTIVES: The purpose of this study was to assess the reproducibility of substantia nigra pars compacta (SNpc) and locus coeruleus (LC) delineation and measurement with neuromelanin-sensitive MRI. MATERIALS AND METHODS: Eleven subjects underwent two neuromelanin-sensitive MRI scans. SNpc and LC volumes were extracted for each scan. Reproducibility of volume and magnetization transfer contrast measurements in SNpc and LC was assessed using intraclass correlation coefficients (ICC) and dice similarity coefficients (DSC). RESULTS: SNpc and LC volume measurements showed excellent reproducibility (SNpc-ICC: 0.94, p < 0.001; LC-ICC: 0.96, p < 0.001). SNpc and LC were accurately delineated between scans (SNpc-DSC: 0.80 +/- 0.03; LC-DSC: 0.63 +/- 0.07). CONCLUSION: Neuromelanin sensitive MRI can consistently delineate SNpc and LC. PMID- 27687626 TI - A study of tumor heterogeneity in a case with breast cancer. AB - Tumor heterogeneity has been suggested based on clinical and pathological findings. Several clinical findings can be explained by tumor evolution during progression and metastasis. We herein report a case of metastatic breast cancer indicated tumor heterogeneity by clinical findings and a genomic analysis. A 64 year-old woman with advanced breast cancer was treated with primary chemotherapy, to which primary tumor responded. After a 6 month treatment pause, lung, liver, and skin metastases developed and her serum tumor markers were elevated. None of those serum markers had been elevated before the treatment, despite the large tumor burden. Notably, there was discordance in the expression of human epidermal growth factor receptor 2 (HER2) between the primary tumor and metastatic skin lesions, with the former being negative and the latter positive. A genomic analysis was performed by in-house Breast Cancer Panel, which consisted of 53 pre selected genes. Twenty-three somatic mutations were found in primary breast tumor and 7 in the skin metastasis. None of these 30 genes matched. However, the cell free (cf) DNA in the plasma taken at the time of skin metastasis contained 10 mutations, 7 from the primary lesion and 3 from the metastasis. These data indicate that the clonal changes or tumor heterogeneity was shown in two solid tumors by clinical and the result of a genomic analysis. Of particular interest was that cell-free DNA could be a powerful tool to look into these dynamic changes. PMID- 27687628 TI - [Which patients with infective endocarditis require emergency surgery?] AB - Half of patients with infectious endocarditis have surgery during the active phase of infective endocarditis (before the end of antibiotic therapy). The American Heart Association and the European Society of Cardiology, independently from each other, have published guidelines in September 2015. As regards surgical indications, these guidelines are similar. The surgical indication must be a common decision of a multidisciplinary team of experts in cardiology, cardiac surgery, imaging and infectious diseases. The main indications are heart failure, non-infectious process control and prevention of embolisms. PMID- 27687630 TI - Surveillance liver MRI for monitoring patients with known or suspected chronic liver disease. PMID- 27687629 TI - Fitness consequences of polymorphic inversions in the zebra finch genome. AB - BACKGROUND: Inversion polymorphisms constitute an evolutionary puzzle: they should increase embryo mortality in heterokaryotypic individuals but still they are widespread in some taxa. Some insect species have evolved mechanisms to reduce the cost of embryo mortality but humans have not. In birds, a detailed analysis is missing although intraspecific inversion polymorphisms are regarded as common. In Australian zebra finches (Taeniopygia guttata), two polymorphic inversions are known cytogenetically and we set out to detect these two and potentially additional inversions using genomic tools and study their effects on embryo mortality and other fitness-related and morphological traits. RESULTS: Using whole-genome SNP data, we screened 948 wild zebra finches for polymorphic inversions and describe four large (12-63 Mb) intraspecific inversion polymorphisms with allele frequencies close to 50 %. Using additional data from 5229 birds and 9764 eggs from wild and three captive zebra finch populations, we show that only the largest inversions increase embryo mortality in heterokaryotypic males, with surprisingly small effect sizes. We test for a heterozygote advantage on other fitness components but find no evidence for heterosis for any of the inversions. Yet, we find strong additive effects on several morphological traits. CONCLUSIONS: The mechanism that has carried the derived inversion haplotypes to such high allele frequencies remains elusive. It appears that selection has effectively minimized the costs associated with inversions in zebra finches. The highly skewed distribution of recombination events towards the chromosome ends in zebra finches and other estrildid species may function to minimize crossovers in the inverted regions. PMID- 27687631 TI - Pd(II) adsorption characteristics of glutaraldehyde cross-linked chitosan copolymer resin. AB - Deliberating upon the role of solution chemistry in influencing the Pd(II) adsorption and desorption characteristics using chitosan based resins, this work addresses the competence of glutaraldehyde cross-linked chitosan (GCC) co-polymer resin for the removal and recovery of Pd(II) from synthetic electroless plating solutions. GCC copolymer adsorbent was prepared by grafting of fixed weight ratio (1/17) of medium molecular weight chitosan and glutaraldehyde (25% in H2O). Within the adsorption parametric range of 2-10pH, 60-300min contact time, 10-50mg adsorbent dosage and 50-500mg/L initial Pd(II) concentration, the solution chemistry associated to synthetic ELP solution has been evaluated to strongly reduce the adsorption capacity of the GCC resin. Batch equilibrium adsorption studies inferred upon the fitness of Langmuir isotherm with a monolayer adsorption capacity of 166.67mg/g. Adsorption kinetics and thermodynamic parametric evaluations affirmed pseudo-second-order kinetics and spontaneous exothermic Pd(II) adsorption on the resin. Further, speciation analysis provided valuable insights by indicating greater favourability of Pd(NH3)42+ species (at pH=8) than PdEDTA-2 (at lower pH) to foster chemisorption with the GCC resin. In summary, the observations affirmed that solution chemistry needs to be addressed in laboratory investigations to further industrial application and competitiveness of alternate resins. PMID- 27687632 TI - Implementing an mHealth system for substance use disorders in primary care: a mixed methods study of clinicians' initial expectations and first year experiences. AB - BACKGROUND: Millions of Americans need but don't receive treatment for substance use, and evidence suggests that addiction-focused interventions on smart phones could support their recovery. There is little research on implementation of addiction-related interventions in primary care, particularly in Federally Qualified Health Centers (FQHCs) that provide primary care to underserved populations. We used mixed methods to examine three FQHCs' implementation of Seva, a smart-phone app that offers patients online support/discussion, health tracking, and tools for coping with cravings, and offers clinicians information about patients' health tracking and relapses. We examined (a) clinicians' initial perspectives about implementing Seva, and (b) the first year of implementation at Site 1. METHODS: Prior to staggered implementation at three FQHCs (Midwest city in WI vs. rural town in MT vs. metropolitan NY), interviews, meetings, and focus groups were conducted with 53 clinicians to identify core themes of initial expectations about implementation. One year into implementation at Site 1, clinicians there were re-interviewed. Their reports were supplemented by quantitative data on clinician and patient use of Seva. RESULTS: Clinicians anticipated that Seva could help patients and make behavioral health appointments more efficient, but they were skeptical that physicians would engage with Seva (given high caseloads), and they were uncertain whether patients would use Seva. They were concerned about legal obligations for monitoring patients' interactions online, including possible "cries for help" or inappropriate interactions. One year later at Site 1, behavioral health care providers, rather than physicians, had incorporated Seva into patient care, primarily by discussing it during appointments. Given workflow/load concerns, only a few key clinicians monitored health tracking/relapses and prompted outreach when needed; two researchers monitored the discussion board and alerted the clinic as needed. Clinician turnover/leave complicated this approach. Contrary to clinicians' initial concerns, patients showed sustained, mutually supportive use of Seva, with few instances of misuse. CONCLUSIONS: Results suggest the value of (a) focusing implementation on behavioral health care providers rather than physicians, (b) assigning a few individuals (not necessarily clinicians) to monitor health tracking, relapses, and the discussion board, (c) anticipating turnover/leave and having designated replacements. Patients showed sustained, positive use of Seva. TRIAL REGISTRATION: ClinicalTrials.gov ( NCT01963234 ). PMID- 27687633 TI - Valuing setting-based recreation for selected visitors to national forests in the southern United States. AB - In this study we estimate selected visitors' demand and value for recreational trips to settings such as developed vs. undeveloped sites in U.S. national forests in the Southern United States using the travel cost method. The setting based approach allows for valuation of multi-activity trips to particular settings. The results from an adjusted Poisson lognormal estimator corrected for truncation and endogenous stratification reveal that economic value per trip estimates are higher for wilderness compared to day-use developed settings, overnight-use developed settings, and general forest areas. Estimates of these economic values are important to resource managers because their management decisions and actions typically control recreational settings. For example, managers control developed campground capacity in a national forest, but typically not the number of campers below the capacity constraint and the number and types of activities visitors engage in during a multi-activity trip to a developed campground (within limits since some activities such as discharging a firearm are not permitted in a developed campground). PMID- 27687634 TI - Radiologically inserted gastrostomy: differences of maintenance of balloon- vs. loop-retained devices. AB - PURPOSE: To compare outcome and associated complications of ballon- vs. loop retained devices for radiologically inserted gastrostomy (RIG). METHODS: From 2007 to 2011 233 patients (age 63.7 +/- 10.6 years) were referred for a RIG because of pharyngeal stricture Intervention was performed with four different devices: balloon-retained - Freka(r) GastroTube, Fresenius Kabi (n = 121); MIC(r) Gastrostomy Feeding Tube, Kimberly-Clark (n = 34); Russell(r) Gastrostomy Tray, Cook Medical Inc. (n = 17); and loop-retained - Tilma(r) Gastrostomy Set, Cook Medical Inc. (n = 50). Follow-up was performed with regard to RIG-related complications, cause of removal and fatalities. Revision-free survival times after RIG were evaluated using Kaplan-Meier analysis and group differences by log rank tests. For analysis of demographic and methodical variables multivariate Cox regression models were used. RESULTS: With a primary technical success rate of 95.3% (222/233) a total of 92 instances of revisions were necessary in 66 patients (66/233, 28.3%) during follow-up (mean 182.8 +/- 86.6 days). The most common complication was tube dislodgement (14.3%). There were no significant differences between the distinct devices (p = 0.098), but analyzing the data in subgroups of balloon-compared to loop-retained gastrostomy tubes we observed a significantly higher probability of minor complications for the latter (p = 0.023). CONCLUSION: As it is significantly less prone to minor complications we recommend the use of balloon-retained gastrostomy tubes to improve the practicability and maintenance of RIG. PMID- 27687635 TI - Alternative functions of the complement protein C1q at embryo implantation site. AB - Complement component C1q is one of the recognition molecules of the complement system which can serve several functions unrelated to complement activation. This molecule is produced at foeto-maternal interface by macrophages as wells as by decidual endothelial cells and invading trophoblast. Foetal trophoblast cells migrating through the decidua in the early stages of pregnancy synthesize and express C1q on their surface, which is actively involved in promoting trophoblast endovascular and interstitial invasion of the decidua. These functions are mediated by two cell surface receptors, gC1qR and alpha4beta1 integrin, which promote trophoblast adhesion and migration through the activation of ERK1/2 MAPKs. C1q-/- mice manifest increased frequency of foetal resorption, reduced foetal weight, and smaller litter size when compared to their wild-type counterparts, suggesting that defective local production of C1q may be involved in pregnancy disorders, such as pre-eclampsia. C1q acts also as a strong angiogenic factor and promotes neovascularization. These studies suggest novel and unexpected roles of this complement component in physiological and pathological pregnancies. PMID- 27687636 TI - Exercise facilities for neurologically disabled populations - Perceptions from the fitness industry. AB - BACKGROUND: People with neurological disabilities (pwND) face many barriers to undertaking physical activity. One option for exercise alongside formal physiotherapy is local fitness facilities but accessibility is often found wanting and gyms are seen as unwelcoming to pwND. OBJECTIVE: The objective of this exploratory study was to investigate the perceptions of fitness facility managers with respect to exercise for pwND in a gym environment. The aim was to identify potential barriers to provision by the fitness industry for pwND. METHODS: The participants included those who were in a position to influence provision at a policy level and those working at management level within fitness providers. A mixed methods approach was used: a quantitative questionnaire and 4 qualitative interviews. Descriptive and correlational analysis, thematic content analysis and concurrent triangulation analysis was undertaken. RESULTS: Specially trained staff is perceived to be necessary to make fitness facilities accessible for pwND. CONCLUSIONS: Ensuring the provision of specially trained staff to support pwND to exercise in gyms may be the main barrier to provision for this population. Investigation into the standard training of fitness professionals combining the expertise of neurological physiotherapists with that of fitness professionals to meet the needs of pwND would be advantageous. PMID- 27687637 TI - Hot-melt extrusion as a continuous manufacturing process to form ternary cyclodextrin inclusion complexes. AB - The aim of this study was to evaluate hot-melt extrusion (HME) as a continuous process to form cyclodextrin (CD) inclusion complexes in order to increase the solubility and dissolution rate of itraconazole (ITZ), a class II model drug molecule of the Biopharmaceutics Classification System. Different CD derivatives were tested in a 1:1 (CD:ITZ) molar ratio to obtain CD ternary inclusion complexes in the presence of a polymer, namely Soluplus(r) (SOL). The CD used in this series of experiments were beta-cyclodextrin (betaCD), hydroxypropyl-beta cyclodextrin (HPbetaCD) with degrees of substitution of 0.63 and 0.87, randomly methylated beta-cyclodextrin (Rameb(r)), sulfobutylether-beta-cyclodextrin (Captisol(r)) and methyl-beta-cyclodextrin (Crysmeb(r)). Rheology testing and mini extrusion using a conical twin screw mini extruder were performed to test the processability of the different CD mixtures since CD are not thermoplastic. This allowed Captisol(r) and Crysmeb(r) to be discarded from the study due to their high impact on the viscosity of the SOL/ITZ mixture. The remaining CD were processed by HME in an 18mm twin screw extruder. Saturation concentration measurements confirmed the enhancement of solubility of ITZ for the four CD formulations. Biphasic dissolution tests indicated that all four formulations had faster release profiles compared to the SOL/ITZ solid dispersion. Formulations of HPbetaCD 0.63 and Rameb(r) even reached 95% of ITZ released in both phases after 1h. The formulations were characterized using thermal differential scanning calorimetry and attenuated total reflectance infra-red analysis. These analyses confirmed that the increased release profile was due to the formation of ternary inclusion complexes. PMID- 27687638 TI - Structure and function of anhydride-modified forms of human insulin: In silico, in vitro and in vivo studies. AB - Insulin is a therapeutic protein whose amyloid formation is reported in diabetic patients. Four anhydride compounds were used in the current study in order to experiment their potential reducing effect on insulin propensity to form amyloid fibrils. The modified forms (obtained with succinic-, 3,3-dimethylglutaric, 2 phenylglutaric-, and (2-Dodecen-1-yl) succinic anhydride), were first characterized with regard to melting temperature (Tm), changes in secondary structure percentage and hydrophobic surface. Fibril formation was then assessed by Congo red absorbance kinetics and transmission electron microscopy. Functionality was investigated with the use of an insulin tolerance test in NMRI mice. Finally, 10ns molecular dynamics simulations were performed during which structural changes, potential energy, gyration radius, RMSD, and accessible surface area were monitored. In all cases, alpha-helical structure content of the modified forms was reduced, but thermal stability and structural compactness of modified insulin were increased except in case of the dodecenylated species. All modified insulin forms undergo amorphous aggregation instead of amyloid fibrils formation, and dodecenylated insulin makes the largest amorphous aggregates. In silico results were overall in accordance with in vitro studies. Finally, only succinylated insulin was functional, although dimethylglutaric-modified insulin started to show some activity after 2h. PMID- 27687639 TI - Influence of barium sulfate X-ray imaging contrast material on properties of floating drug delivery tablets. AB - The objective of the study was to reveal the influence of necessarily added barium sulfate (BaSO4) X-ray contrast material on floating drug delivery tablets. Based on literature survey, a chosen floating tablet composition was determined containing HPMC and carbopol 943P as matrix polymers. One-factor factorial design with five levels was created for evaluation of BaSO4 (X1) effects on experimental parameters of tablets including: floating lag time, total floating time, swelling , erosion-, dissolution-, release kinetics parameters and X-ray detected volume changes of tablets. Applied concentrations of BaSO4 were between 0 and 20.0% resulting in remarkable alteration of experimental parameters related especially to flotation. Drastic deterioration of floating lag time and total floating time could be observed above 15.0% BaSO4. Furthermore, BaSO4 showed to increase the integrity of tablet matrix by reducing eroding properties. A novel evaluation of dissolutions from floating drug delivery systems was introduced, which could assess the quantity of drug dissolved from dosage form in floating state. In the cases of tablets containing 20.0% BaSO4, only the 40% of total API amount could be dissolved in floating state. In vitro fine resolution X-ray CT imagings were performed to study the volume change and the voxel distributions as a function of HU attenuations by histogram analysis of the images. X-ray detected relative volume change results did not show significant difference between samples. After 24h, all tablets containing BaSO4 could be segmented, which highlighted the fact that enough BaSO4 remained in the tablets for their identification. PMID- 27687640 TI - Are Sonographically Measured Vascular Haemodynamic Parameters Reproducible Using Magnetic Resonance Imaging? AB - OBJECTIVE/BACKGROUND: Hemodynamic measurements of blood flow in the common femoral vein and artery can be performed readily using duplex sonography. The ratio of venous to arterial volume flow in these vessels, the venous arterial flow index (VAFI), is increased in patients with varicose veins and/or chronic venous disease. The objective was to determine the reproducibility of sonographically measured hemodynamic flow parameters using phase contrast magnetic resonance imaging (MRI). METHODS: Based on hemodynamic volume flow measurements from the common femoral vein and artery the VAFI was calculated in seven patients with varicose veins (C2, Ep, As, Pr) and 32 healthy controls using standard duplex sonography and MRI. RESULTS: Based on duplex sonography, the average VAFI (VAFI_d) was 1.05 +/- 0.17. The same ratio, using MRI (VAFI_mri) was 1.05 +/- 0.19. There was a significant correlation between the VAFI_d and the VAFI_MRI (p = .0021). In patients with venous disease, the average VAFI_d and VAFI_mri were 1.36 +/- 0.21 and 1.36 +/- 0.20, respectively. In contrast, in the healthy cohort the VAFI_d was 1.00 +/- 0.12 and the VAFI_mri measured 1.01 +/- 0.15. As expected, there was a significant difference between the VAFI measured in those with venous disease when compared with that of healthy controls (p < .0001). CONCLUSION: There is a significant correlation between the VAFI measured using sonography and MRI. The study confirmed the elevation of VAFI in patients with chronic venous disease. PMID- 27687641 TI - Antibiotics in late clinical development. AB - Most pharmaceutical companies have stopped or have severely limited investments to discover and develop new antibiotics to treat the increasing prevalence of infections caused by multi-drug resistant bacteria, because the return on investment has been mostly negative for antibiotics that received marketing approved in the last few decades. In contrast, a few small companies have taken on this challenge and are developing new antibiotics. This review describes those antibiotics in late-stage clinical development. Most of them belong to existing antibiotic classes and a few with a narrow spectrum of activity are novel compounds directed against novel targets. The reasons for some of the past failures to find new molecules and a path forward to help attract investments to fund discovery of new antibiotics are described. PMID- 27687642 TI - Search for new compounds from Kitasato microbial library by physicochemical screening. AB - The Omura research group of the Kitasato Institute has isolated multiple microorganisms over a period of five decades. The resulting collection comprises a broad spectrum of microbes, including strains producing novel and diverse compounds with biological activities. A bioassay-guided fractionation of microbial culture broths has been employed to screen the microbial collection for compounds with new biological activities. And numerous novel natural products have been discovered among the microbial metabolites produced by members of the collection. However, dereplication of already known compounds and their potential analogs is a vital part of the discovery process of new microbial natural products. Recently, it has become easy to acquire the ultraviolet (UV) and mass spectrometry (MS) spectra of many single components of microbial culture broths in combination with high-performance liquid chromatography. To achieve most effective utilization of our microbial library, new compounds from microbial culture broths were investigated by employing an approach based on the physico chemical properties using spectral analyses such as UV and MS and color reaction, collectively designated as physicochemical (PC) screening. As a result of physicochemical screening, many new compounds were identified among the secondary metabolites of fresh isolated rare actinomycetes and Streptomyces spp. preserved for a long time as producer of biological compounds. In this review, we introduce the Kitasato microbial library and the new compounds discovered from the library by PC screening. PMID- 27687643 TI - Reduced metabolic activity of gut microbiota by antibiotics can potentiate the antithrombotic effect of aspirin. AB - In this study, we investigated the effects of antibiotics on the pharmacological effects of aspirin. The antithrombotic activity of aspirin was evaluated after antibiotic treatment using tail bleeding assay. The pyrosequencing analysis and selective medium culture assay were performed to investigate the alterations in gut microbiota. In addition, the in vitro metabolism assay with fecal suspension and in vivo pharmacokinetic experiments with antibiotic treatment were conducted. Ampicillin treatment significantly prolonged the bleeding time in aspirin-dosed rats. Oral administration of ampicillin significantly reduced gut microbial aspirin-metabolizing activity by 67.0% in rats. Furthermore, systemic exposure to aspirin and its primary metabolite (M1) was significantly increased in ampicillin treated rats. The results from the pyrosequencing and selective medium culture with rat fecal samples revealed that ampicillin treatment led to the changes of the amounts and composition profile of gut microbiota. These findings suggest that co-administration of antibiotics can modulate the metabolism and pharmacokinetics of aspirin via suppression of metabolic activity of gut microbiota, which could potentiate the therapeutic potency of aspirin.

AB - OBJECTIVE: To study the changes in the physiological parameters and gene expression of two drug efflux transporters MDR1 and MRP2 in the small intestine, liver and kidney of rats exposed to acute hypoxia. METHODS: Eighteen Wistar rats were randomly divided into control group, hypoxia for 24 h group and hypoxia for 72 h group. Blood samples were obtained from the abdominal aorta of the rats after the exposure for analyzing the physiological indexes. The mRNA expressions of MDR1 and MRP2 were determined using Real-Time PCR, and their protein expressions were detected with enzyme-linked immunosorbent assay (ELISA). RESULTS: The physiological parameters of the rats in hypoxia group were significantly changed compared with those in the control group. The expressions of MDR1 and MRP2 mRNA and proteins in the small intestine, liver and kidney were significantly increased in rats with hypoxic exposure than in the control rats (P<0.05 or 0.01). As the hypoxic exposure prolonged, the two transporters showed different patterns of variation in different tissues. CONCLUSION: Acute hypoxia affects the physiological parameters and expression levels of MDR1 and MRP2, thus causing changes in the metabolism of the substrates of the transporters. These changes may play an important role in the pharmacokinetics of drugs at a high altitude. PMID- 27687644 TI - Hemodynamic effects of sustained postoperative cardiac resynchronization therapy in infants after repair of congenital heart disease: Results of a randomized clinical trial. AB - BACKGROUND: It is unknown whether continuous cardiac resynchronization therapy (CRT) can lead to sustained improvement in hemodynamics after surgery for congenital heart disease (CHD). OBJECTIVE: We investigated whether CRT improves cardiac index (CI) and blood pressure in infants after biventricular repair of CHD. METHODS: We randomized infants younger than 4 months after biventricular CHD surgery to standard care or standard care plus CRT for 48 hours or until extubation if sooner. Change in the primary outcome of CI and blood pressure over time was compared between groups. For subgroup analysis, QRS duration was considered prolonged if greater than the 98th percentile. RESULTS: Forty-two patients were randomized: 21 controls and 21 patients receiving CRT (median weight 4 kg). There were no identified adverse events from pacing. The change in CI over time was not different between patients receiving CRT and controls, but trended toward improvement in patients with wide QRS who received CRT (n = 9) vs controls with wide QRS (n = 8) (+1.65 (0.86) L/(min.m2); P = .06). Controls with wide QRS experienced the smallest increase in CI (0.33 L/(min.m2)). Blood pressure was significantly higher in infants with wide QRS who received CRT than in controls (+7.14 (3.08) mm Hg; P = .02). Serum lactate level, catecholamine use, ventilation time, and length of intensive care unit stay were similar between the 2 groups. CONCLUSION: CRT improved blood pressure and a trend toward higher CI in infants after repair of biventricular CHD with prolonged QRS duration. These findings warrant further study of CRT to improve postoperative recovery in infants with electrical dyssynchrony.

AB - OBJECTIVE: To investigate the characteristic 18F-FDG PET/CT findings in patients with primary intestinal lymphoma (PIL). METHODS: We collected the clinical and 18F-FDG PET/CT data of 23 patients with PIL who underwent 18F-FDG PET/CT in our center between January, 2005 and January, 2016. The location, morphologies and metabolic features of the lesions were analyzed in these patients. RESULTS: In the 23 PIL patients, diffusive large B cell lymphoma (DLBCL) and enteropathy- associated T cell lymphoma (EATL) were the primary histopathological types, accounting for 47.8% and 43.4% of the total patients, respectively. The ileum, ileocecus and ascending colon were the most commonly compromised locations (57.0%). All the 42 intestinal lesions showed 18F-FDG-avid foci with a mean SUVmax of 15.2?8.1 (range 3.6-33.7), and no significant difference was found in SUVmax between DLBCL and EATL groups (t=1.851, P=0.073). Diffusive regular or irregular intestinal wall thickening was the primary CT finding in PIL lesions without significant difference between the two groups (chi2=0.426, P=0.514). The aneurismal sign was found in 26.2% (11/42) lesions, more commonly seen in the patients with DLBCL than in those with EATL (chi2=8.101, P=0.004). PET/CT detected abdominal lymph node involvement of lymphoma was detected in 56.5% of the patients, and a small quantity of asites was seen in 30.4% of the patients. CONCLUSION: PIL presents with characteristic imaging features in 18F-FDG PET/CT. 18F-FDG PET/CT is a sensitive imaging modality for detecting inter- and extra intestinal lesions of PIL and displays characteristic imaging features of the disease.

AB - OBJECTIVE: To explore the effect of exposure to vehicle exhaust in pregnant mice on the reproductive function and DNA methylation in male offspring mice. METHODS: Twenty pregnant mice were randomized into control group and vehicle exhaust exposure group (n=10) and exposed to routine laboratory condition and to vehicle exhaust for 10 consecutive days (8 h per day) in a tunnel with a heavy traffic, where the concentrations of TSP, PM10, PM2.5, SO2 and NOX and the decibel of noise were measured. The offspring mice were raised till reaching maturity, and the epididymides of the male mice were collected to test the weight coefficients, DNA methylation level, and mRNA levels of Aldh7a1 and Rpe. RESULTS: The body weight and the weight coefficients of the epididymides and testes differed significantly between the exposure group and the control group (P>0.05). The concentrations of TSP, PM2.5, PM10 and NOx and the decibel of noise were significantly higher in the traffic environment and the control environment (P<0.05). Reduced representation bisulphite sequencing (RRBS) and Gene ontology (GO) showed that 58 genes had significantly different methylation levels between the two groups, mostly relating to the process of spermatogenesis (P<0.05). Compared with the control group, Aldh7a1 and Rpe mRNA expressions in the testes were down-regulated significantly in the exposure group (P<0.05). CONCLUSION: Exposure of pregnant mice to vehicle exhaust causes damages of the reproductive function in the male offspring mice. PMID- 27687648 TI - [Efficacy of Yunnan Baiyao as an adjuvant treatment for active ulcerative colitis: an open-label randomized controlled study]. AB - OBJECTIVE: To investigate the efficacy of Yunnan Baiyao (YNBY)as an adjuvant treatment of active ulcerative colitis. METHODS: A total of 221 patients with active ulcerative colitis were randomized into YNBY group (78 cases) and control group (143 cases). The patients were followed up for 26 weeks and time of remission and serological data (WBC, HGB, PLT, and CRP) were recorded. RESULTS: The patients receiving YNBY as an adjuvant therapy had a median remission time of 9 weeks (95% CI: 8.293-9.707), significantly shorter than that of 13 weeks (95% CI: 11.855-14.145) in the control patients (P<0.001). According to the extent of the lesion, both YNBY group and control group were classified into E1, E2 and E3 subgroups, and the median remission time was 7 versus 11 weeks in E1 subgroups (P=0.09), 10 versus 13 weeks in E2 subgroups (P=0.04), and 9 versus 14 weeks in E3 subgroups (P<0.001). According to the disease severity, the patients in YNBY group and control group had a median remission time of 9 versus 10 weeks in mild cases (P=0.568), 9 versus 14 weeks in moderate cases (P<0.001), and 11 versus 20 weeks in severe cases (P=0.001). According to the standard treatment received, the median remission time in YNBY group and control group was 9 versus 12 weeks in those receiving mesalazine (P<0.001), 9 versus 13 weeks in those receiving corticosteroid (P=0.001), and 7 versus 14 weeks in those receiving infliximab (P=0.04). Cox proportional hazards regression analysis showed that YNBY was a protective factor for disease remission. The remission time was shortened by 2.283 times (95% CI: 1.69-3.070, P<0.001) in patients having YNBY as an adjuvant treatment compared to the control group. CONCLUSION: Patients with active ulcerative colitis can benefit from YNBY as an adjuvant treatment, which shortens the time of disease remission, relieves the symptoms and improves the quality of life of the patients. PMID- 27687649 TI - [Effect of chronic arsenic exposure on mouse brain tissue and serum metabolomics]. AB - OBJECTIVE: To observe the effect of chronic arsenic exposure on cerebral cortex and serum metabolics of mice and explore the mechanism of arsenic neurotoxicity. METHODS: Twelve 3-week-old male C57BL/6J mice were randomly assigned into exposure group and control group and exposed to sodium arsenite (50 mg/L) via drinking water and deionized water for 12 weeks, respectively. After the exposure, arsenic level in the cerebrum was determined by hydride generation atomic fluorescence spectrometry. The metabolites in the cerebral cortex and serum were determined using gas chromatography-mass spectrometry (GC/MS) analysis. Principal component analysis (PCA) was used to analyze the difference of the metabolites between the exposure and the control groups. Online tools for analyzing metabolic pathways were used to identify the related metabolites pathways. RESULTS: Arsenic content in the brain of exposure group was significantly higher than that in the control group (P<0.05). The mice exposed to arsenic had a higher level of citric acid, phenylalanine, tyrosine, histidine and lysine in the cerebral cortex (P<0.05). Serum levels of serine, glycine, proline, aspartate and glutamate were significantly higher while alpha-ketoglutaric acid level was significantly lower in the exposure group than in the control group (P<0.05). PCA analysis showed a significant difference in cerebral cortex and serum metabolites between the two groups. CONCLUSION: Chronic arsenic exposure may affect the function of the central nervous system by interfering with amino acid metabolism and tricarboxylic acid cycle, which may be one of the mechanisms of arsenic neurotoxicity. PMID- 27687650 TI - [Effects of bisoprolol pretreatment on hypoxia/reoxygenation-induced injury in H9c2 cardiomyocytes]. AB - OBJECTIVE: To investigated the effects of bisoprolol pretreatment on hypoxia/reoxygenation (H/R)-induced injury in H9c2 cardiomyocytes. METHODS: Cultured H9c2 cells were exposed to hypoxia for 6 h followed by reoxygenation for 2 h with or without pretreatments with bisoprolol or bisoprolol + LY294002. The cell survival was measured by MTT assay, and the cell apoptosis and levels of radical oxygen species (ROS) were evaluated with flow cytometry. The protein levels of phosphyorylated AKT and phosphorylated GSK3beta in the cells were determined by Western blotting. RESULTS: Compared with the normal control cells, the cells exposed to H/R injury showed significantly decreased cell survival and increased cell apoptosis and ROS production; pretreatment of the cells with bisoprolol significantly decreased the cell apoptotic rates and ROS production and obviously enhanced the cell survival and protein levels of p-AKT and p GSK3beta in the exposed cells. The protective effect of bsioprolol against H/R induced cell injury was significantly attenuated by LY294002. CONCLUSION: Bisoprolol can protect H9c2 cells against H/R-induced injury and oxidative stress by activating PI3K/AKT/Gsk-3beta pathway to increase the phosphorylation of AKT and GSK3beta and reduce ROS production. PMID- 27687651 TI - [Correlation of DNase I in serum and synovial fluid with inflammatory activity in patients with rheumatoid arthritis]. AB - OBJECTIVE: To investigate the potential role of deoxyribonuclease I (DNase I) in the pathogenesis of rheumatoid arthritis (RA). METHODS: DNase I activity was measured by radial enzyme-diffusion method in serum samples from 83 RA patients and 60 healthy volunteers and in the synovial fluid (SF) from 27 RA patients and 38 patients with other inflammatory arthritis. SF cfDNA level was measured with Pico Green Kit, and the correlation among DNase I activity, cfDNA level and clinical parameters of RA patients was analyzed. RESULTS: Serum DNase I activity was significantly lower in RA patients than in the healthy control subjects (0.3065?0.1436 vs 0.4289?0.1976 U/mL, P<0.001), and was negatively correlated with ESR (r=-0.2862, P=0.0122), CRP (r=-0.2790, P=0.0184) and neutrophil cell counts (r=-0.287, P=0.011). SF DNase I activity was almost negative in patients with RA, ankylosing spondylitis (AS) and gouty arthritis (GA). SF cfDNA level in RA patients was significantly higher than that in patients with osteoarthritis (100.81?142.98 vs 18.98?31.40 ug/mL, P=0.002), but similar to that in patients with AS (45.85?47.67 ug/mL, P=0.428) and GA (162.95?97.49 ug/mL, P=0.132). In patients with inflammatory arthritis, SF cfDNA level was positively correlated with ESR (r=0.4106, P=0.0116) and CRP (r=0.5747, P=0.0002). CONCLUSION: Impairment of DNase I activity may be responsible for the enhanced NETs generation and plays a role in the pathogenesis of RA. PMID- 27687652 TI - [P38 MAPK signaling pathway mediates advanced oxidation protein product-induced epithelial-to-mesenchymal transition in tubular cells]. AB - OBJECTIVE: To investigate whether the p38 mitogen-activated protein kinase (MAPK) signaling pathway mediates advanced oxidation protein products (AOPPs)-induced epithelial-to-mesenchymal transition (EMT) in tubular cells. METHODS: Human proximal tubular cells (HK-2 cells) exposed to AOPP-bovine serum albumin (BSA) were examined for expressions of p38 MAPK and phosphorylated p38 MAPK using Western blotting. Western blotting and quantitative RT-PCR were used to examine the protein and mRNA expressions of EMT markers E-cadherin and vimentin and endoplasmic reticulum stress marker glucose-regulated protein (GRP) 78 in cells treated with SB203580 (an inhibitor of the p38 MAPK signaling pathway) prior to AOPP exposure. The cells treated with AOPPs following pretreatment with salubrinal (an inhibitor of endoplasmic reticulum stress) were also examined for expressions of p38 MAPK and phosphorylated p38 MAPK. RESULTS: AOPP treatment induced the phosphorylation of p38 MAPK in HK-2 cells. AOPP-induced decrease in E cadherin expression and overexpression of vimentin and GRP78 were partly inhibited by pretreatment of the cells with SB203580. Salubrina partly suppressed AOPP-induced phosphorylation of p38 MAPK in the cells. CONCLUSION: p38 MAPK signaling pathway, which is regulated by endoplasmic reticulum stress, might mediate AOPP-induced EMT in HK-2 cells. PMID- 27687653 TI - [Correlation of CD4+CD29+ regulatory T cells with recurrence and survival time in patients with non-small cell lung cancer]. AB - OBJECTIVE: To investigate the correlation of CD4+CD29+ regulatory T cells (Treg) with tumor recurrence and survival time in patients with non-small cell lung cancer (NSCLC). METHODS: Fifty-nine patients with NSCLC treated with radical surgery were followed up for 5 years. Blood Treg cells were examined during the follow-up using flow cytometry (FCM). The sensitivity and specificity of Treg cells to predict recurrence of NSCLC were analyzed using receiver-operating characteristic (ROC) curve and compared with those of carcinoembryonic antigen (CEA) and cytokeratin21-1 (Cyfra21-1). The influences of gender, age, occupation and radiotherapy on survival time of the patients were analyzed with Kaplan-Meier method. RESULTS: Among the 59 patients, the shortest survival time was 23 months while the longest time was over 67 months. Nineteen patients had NSCLC recurrence, and 17 (28.81%) of them died of metastasis during the follow-up. The frequencies of blood Treg cells in patients who did not receive radiotherapy and in patients with tumor recurrence were significantly higher than those in patients receiving radiotherapy and in patients free of recurrence (P=0.000). ROC curves showed that the area under curve (AUC) lowered in the order of Treg cells, Cyfra21-1, CEA (P=0.002, 0.006 and 0.013, respectively) with 95% confidence interval (CI) of 0.649-0.981, 0.621-0.936 and 0.584-0.944, respectively. At the cut-off value of 7.53%, the sensitivity and specificity of Treg cells to predict NSCLC recurrence was 91.42% and 87.59%, respectively. The five-year survival rate of the 59 patients was 71.18% (42/59), and Kaplan-Meier analysis revealed a longer survival time in female patients (P=0.038), in patients below 50 years of age (P=0.013), in patients not engaging in mental work (P=0.029), and in patients receiving radiotherapy (P=0.003). CONCLUSION: Treg cells has a better efficiency than Cyfra21-1 and CEA to predict tumor recurrence in patients with NSCLC following radical surgery. The male gender, an age beyond 50 years, an occupation of mental work, and failure to receive radiotherapy are all risk factors for recurrence of NSCLC. PMID- 27687654 TI - [Association of waist-to-hip ratio with chronic kidney disease in non-diabetic subjects]. AB - OBJECTIVE: To explore the relationship between waist-to-hip ratio (WHR) and chronic kidney disease (CKD) in non-diabetic subjects and compare the difference between male and female subjects. METHODS: We performed a cross-sectional survey among 2142 community-based southern Chinese participants without diabetes from June to October 2012. We divided all the participants into 4 groups according to the gender-specific quartiles of WHR. Logistic regression models were used to explore the associations of WHR with CKD in these subjects. RESULTS: In the unadjusted model, WHR was significantly associated with CKD in women (OR=7.29, 95% CI: 3.56-16.32, P<0.001), and the association was still significant (OR=6.13, 95% CI: 2.56-15.20, P=0.003 ) after adjustment for the potential confounders (including age, history of hypertension, coronary heart disease, current smoker, physical inactivity, education level, systolic blood pressure, diastolic blood pressure, serum triglyceride, serum high density lipoprotein, blood glucose, and BMI). The odds ratio (OR) for having CKD in the highest versus lowest quartile of WHR levels was 2.44 (95% CI: 0.98-4.97, P=0.103) in men in the unadjusted model. CONCLUSION: WHR levels are associated with CKD in non-diabetic women but not in non-diabetic male subjects. PMID- 27687655 TI - [Role of specificity protein 1 in modulating radiosensitivity of cervical cancer cell lines]. AB - OBJECTIVE: To investigate the role of specificity protein 1 (Sp1) in regulating radiosensitivity of cervical cancer cell lines. METHODS: We analyzed Sp1 expression in 6 different cervical cancer cell lines (SiHa, HeLa, Caski, Me180, Ms751, and C33a) using Western blotting and real-time PCR. Clonogenic survival assay and curve fitting were used to assess the changes in radiosensitivity of Me180 cells transfected with lentivirus-mediated shRNA vector targeting sp1 and HeLa cells transfected with sp1 over-expression vector. RESULTS: In the 6 cell lines tested, the cellular expression levels of Sp1 decreased gradually in the order of Me180, Caski, C33a, SiHa, Ms751, and HeLa. SP1 knockdown with lentivirus mediated shRNA significantly lowered the survival rate of Me180 cells following radiation exposure (P<0.05), and obviously lowered the values of SF2, D0 and Dq but significantly increased alpha/beta of the cells. Compared with the cells transfected with the mock vector, HeLa cells with sp1 over-expression showed a significantly increased survival following radiation exposure (P<0.05) with obviously increased values of SF2, D0 and Dq but significantly lowered alpha/beta. CONCLUSION: Silencing Sp1 can increase the radiosensitivity while Sp1 overexpression enhances the radioresistance of cervical cancer cell lines, suggesting an important role of Sp1 in radiotherapy for cervical cancer. PMID- 27687656 TI - [Correlation of serum omentin-1 and chemerin with gestational diabetes mellitus]. AB - OBJECTIVE: To investigate the relationship of serum omentin-1 and chemerin with gestational diabetes mellitus (GDM). METHODS: Serum levels of omentin-1 chemerin, glycolipids biochemical index, inflammation index, fasting insulin (FINS), and insulin resistance indexes (HOMA-IR) were determined in 85 women with GDM and 85 pregnant women with normal glucose tolerance (NGT). RESULTS: BMI, FPG, hs-CRP, blood lipids, blood glucose, FINS, HOMA-IR and serum chemerin level were all significantly higher while serum omentin-1 significantly lower in GDM group than in NGT group (P<0.05). In both groups, serum omentin-1 level was significantly lower and serum chemerin was significantly higher in obese subjects than in the non-obese subjects (P<0.05). Obesity before delivery and/or HOMA-IR >=2 was associated with a significantly decreased serum omentin-1 level; serum chemerin increased significantly in obese women before delivery but was not associated with HOMA-IR. Serum omentin-1 level was positively correlated with HDL but inversely with BMI (at pregnancy and before delivery), FPG, FINS and HOMA-IR; Chemerin was positively correlated with TC, TG, hs-CRP and FPG; serum omentin-1 and chemerin levels were not significant correlated (P=0.301). In women with GDM, BMI at pregnancy, TG, FPG, and FINS were all independent factors affecting serum omentin-1; TG, LDL, and hs-CRP were independent factors affecting serum chemerin. CONCLUSION: An decreased serum omentin-1 can be indicative of glucose and lipid metabolism disorder and insulin resistance, and an increased serum chemerin level indicates hyperlipidemia and chronic inflammation in pregnant women. Both of the adipokines are closed associated with GDM and probably participate in the occurrence and development of GDM. PMID- 27687657 TI - [Distribution of podophyllotoxin-loaded nanostructured lipid carriers after topical application on cervical mucosa in Tibet minipigs]. AB - OBJECTIVE: To assess the distribution and systemic toxicity of podophyllotoxin loaded nanostructured lipid carriers (POD-NLC) after topical application on the cervical mucosa in Tibet minipigs. METHODS: Twelve Tibet mini-pigs were randomized into test group and control group to receive topical application of 0.5% POD-NLC and 0.5% POD tincture, respectively, on the cervical mucosa. Cervical mucosal irritation, targeted distribution and systemic absorption of POD were observed at different time points within 24 h after the drug application. RESULTS: No local inflammation reaction was observed in the test group, while serious local irritations (swelling, blisters, blood blisters, erosion and ulceration) occurred in the control group. The fluorescence intensity of POD in the mucosal tissue reached the peak level at 4 h after drug application in the control group, while the POD fluorescence intensity increased slowly and reached the peak level at 16 h in the test group. The peak blood POD concentration occurred at 6 h after POD-NLC application in the test group (14.28?0.33 ng/mL), as compared to 4 h in the control group (42.46?0.32 ng/mL). At all the time points within 24 h, blood POD concentration remained significantly lower in the test group than in the control group (P<0.05), and the area under curve of blood POD concentration in the control group was 1.38-fold greater than that in the test group. CONCLUSION: POD-NLC allows sustained release of POD and achieves a higher POD concentration in the mucosal tissue without causing local irritation or obvious systemic toxicity in Tibet minipigs. PMID- 27687658 TI - [Construction of a lentivirus vector expressing wheat germ agglutinin and its infection in human adipose-derived stem cells]. AB - OBJECTIVE: To construct a lentivirus vector carrying wheat germ agglutinin (WGA) and evaluate its ability of tracing WGA in the brain of mice with ischemic brain injury. METHODS: WGA gene was inserted into the lentiviral vector Plvx IRES ZsGreen1 using genetic engineering methods. 293T cells were transfected with the vector and 3 packaging plasmids (RPEV, PRRE, and VSVG) to obtain the recombinant lentivirus for infection of human adipose-derived stem cells (hADSCs). The infected hADSCs were injected into the damaged brain area by in situ injection in a mouse model of middle cerebral artery occlusion (MCAO) and the expression of GFP was traced. RESULTS: Immunofluorescence identification detected WGA protein expression in the infected hADSCs, which survived in the infarct area of mice with MCAO. CONCLUSION: Packaging WGA gene in lentivirus is a reliable approach to allow efficient neuroanatomical tracing of various cells. PMID- 27687659 TI - [Comparison of endothelial differentiation capacity of adipose-derived stem cells and bone marrow mesenchymal stem cells from rats]. AB - OBJECTIVE: To compared the differentiation capacity of rat adipose-derived stem cells (ASCs) and bone marrow mesenchymal stem cells (BMSCs) into endothelial cells. METHODS: Rat BMSCs and ASCs were isolated, cultured and identified for cell surface markers using flow cytometry. The cell growth curves were drawn by CCK-8 assay, and the cells in active growth were induced for endothelial differentiation following standard protocols. On day 21 of induction, the cells were examined for mRNA expressions of endothelial cell specific markers CD31, KDR, and vWF using qPCR. Immunostaining was performed to observe the expression of CD31 on the cells. The induced cells were also tested for Dil-labeled acetylated low-density lipoprotein (ac-LDL) uptake ability. The tube-forming ability of the induced cells was verified on Matrigel. RESULTS: We successfully isolated rat ASCs and BMSCs. Morphologically, ASCs were similar with BMSCs, both having long spindle-shaped and fibroblast-like morphology. Flow cytometry showed that both BMSCs and ASCs had high expressions of mesenchymal markers CD29 and CD90 and a low expression of hematopoietic cell surface markers CD45. CCK-8 assay showed that ASCs proliferated more quickly than BMSCs. The cells with induced endothelial differentiation exhibited increased levels of CD31, KDR, and vWF mRNA expressions and immunofluorescent staining identified CD31 antigen expression on the cell membrane. Fluorescence microscopy revealed red fluorescence in the induced cells suggesting uptake of Dil-Ac-LDL by the cells. The induced cells were capable of forming tube on Matrigel, confirming their identity of endothelial cells. CONCLUSION: Both rat BMSCs and ASCs can be induced to differentiate into endothelial cells, but ASCs differentiate more quickly into endothelial cells and possess a stronger proliferation ability, suggesting its greater potential than BMSCs in future applications. PMID- 27687660 TI - [Propofol suppresses migration and invasion of breast cancer MDA-MB-231 cells by down-regulating H19]. AB - OBJECTIVE: To explore the effect of propofol on H19 expression, migration and invasion of human breast cancer MDA-MB-231 cells in vitro. METHODS: MDA-MB-231 cells were randomly divided into 5 groups for treatment with basal medium, DMSO, or propofol at concentrations of 25, 50, and 100 umol/L. H19 expression of the treated cells was assessed with RT-PCR, and the changes of cell motility, migration and invasion were evaluated with wound-healing assay and Transwell assays. RESULTS: Treatment of the cells with 25, 50, and 100 umol/L propofol for 24 h down-regulated H19 by 17.83%, 37.50% and 63.67% (P<0.05), and suppressed cell motility by 13.46%, 36.54% and 46.17% (P<0.05), cell migration by 27.93%, 57.90% and 76.51% (P<0.05), and cell invasion by 25.72%, 53.32% and 81.43% (P<0.05), respectively. CONCLUSION: Propofol-induced cell migration and invasion suppression are partially mediated by down-regulating H19 in MDA-MB-231 cells in vitro. PMID- 27687661 TI - [Super-resolution reconstruction for 4-dimensional computed tomography of the lung using graph cuts]. AB - Four-dimensional computer tomography (4D-CT) has a great value in lung cancer radiotherapy for its capability in providing lung information with respiratory motion. We employed a global graph cuts super-resolution (SR) reconstruction method to reconstruct high-resolution lung 4D-CT images. First, the high resolution images reconstruction energy function was built based on a Maximum a posteriori Markov Random Field (MAP-MRF) formulation. The energy function was then transformed to a graph formulation, which was solved using graph cut algorithm. All the evaluation results showed that this approach outperformed the line interpolation and projection onto convex sets (POCS) approach with an improved structural clarity.

AB - OBJECTIVE: To explore the molecular mechanism responsible for apoptosis of PC-12 neuronal cells induced by oxygen-glucose deprivation (OGD). METHODS: PC12 cells were exposed to OGD for 24 h to simulate ischemia-reperfusion injury. Flow cytometry was employed detect the cell apoptosis, and the expresions of TRPM8, UCP4, cAMP and PKA in the exposed cells were detected with RT-PCR and Western blotting. The changes in the expressions of Bax, Bcl-2, cAMP, PKA and UCP4 proteins were detected in the exposed cells in resposne to inhibition of TRPM8 and cAMP-PKA signal or over-expression of UCP4. RESULTS: OGD for 24 induced obvious apoptosis in PC-12 cells and caused TRPM8 over-expression and inhibition of UCP4 and cAMP-PKA signaling. Inhibiting TRPM8 expression reduced the cell apoptosis and up-regulated cAMP, p-PKA and UCP4 in the cells exposed to OGD. In cells exposed to OGD, inhibition of TRPM8 and cAMP-PKA signaling suppressed the expressio of UCP4 and increased the cell apoptosis. CONCLUSION: TRPM8 mediates OGD-induced PC12 cell apoptosis through cAMP-PKA/UCP4 signaling. PMID- 27687663 TI - [Expression of CDK6 in early ovarian cancer and its clinical significance]. AB - OBJECTIVE: To explore the expression of CDK6 in early ovarian cancer and explore its clinical significance. METHODS: Real-time PCR and immunohistochemistry was used to examine the differential expression of CDK6 mRNA and protein in ovarian cancer and normal ovarian tissues. The correlation of CDK6 expression with the clinical characteristics and prognosis of the patients was analyzed. RESULTS: The expression of CDK6 mRNA was obviously up-regulated in 36 ovarian cancer tissues as compared to that in 16 ovarian tissues. Immunohistochemistry demonstrated that CDK6 protein was expressed in both the cytoplasm and cell nuclei. Compared with the 48 normal ovarian tissues, the 121 ovarian cancer tissues showed significantly up-regulated CDK6 protein expression (P=0.044). Increased CDK6 protein expression was not significantly correlated with the clinical features of the patients with ovarian cancer, but showed a significant negative correlation with the patients' prognosis (P=0.006). Multivariate analysis suggested that CDK6 expression level was an independent prognostic indicator (P=0.008) for the survival of patients with ovarian cancer. CONCLUSION: Increased CDK6 protein expression may promote the development and progression of early ovarian cancer. PMID- 27687664 TI - [Relationship between vitamin D receptor gene polymorphism and preterm birth]. AB - OBJECTIVE: To explore the relationship between vitamin D receptor (VDR) gene pol ymorphisms at Fok I site and the risk of preterm birth for potential intervention of of preterm birth or threatened premature delivery. METHODS: Fifty-seven women with preterm birth and 84 with full-term birth were included in this analysis. Polymerase chain reaction-restriction frag-ment length polymorphism (PCR-RFLP) was performed to identify VDR gene Fok I geno-types. RESULTS: No significant difference was found in age, D-dimer (DDI), fibrinogen (Fg), serum calcium (Ca2+), leukocyte count or glycosylated hemoglobin (HbA1c) level between the women in the preterm and full-term birth groups (P>0.05). The two groups differed signifi-cantly in the distribution of VDR gene Fok I site genotypes and allele frequency of F/F (P<0.05).The frequency of FF genotype was significantly higher in the preterm group than in the full-term group. Compared with Ff and ff genotypes, FF genotype was associated with an in-creased risk of preterm delivery (chi2=9.701, P=9.701, OR=3.320, 95% CI [1.560, 7.066]). In the preterm group, the maternal age, DDI, Fg, serum Ca2+, leukocyte count or HbA1c did not differ significantly between the genotypes (P>0.05). CONCLUSION: VDR gene Fok I site geno-types are related with preterm birth, and the FF genotype may serve as a potential risk factor for preterm birth. PMID- 27687665 TI - [Prognostic value of preoperative carcinoembryonic antigen level in patients with stage I-III colorectal cancer]. AB - OBJECTIVE: To evaluate the prognostic value of preoperative serum carcinoembryonic antigen (CEA) level in patients with stage I-III colorectal cancer. METHODS: The clinicopathological data and prognosis were retrospectively analyzed for 393 patients with colorectal cancer treated in our hospital from January, 2003 to December, 2013. Of these patients, 136 had elevated serum CEA level (>=5 ng/mL) and 257 did not show serum CEA elevation (<5 ng/mL). RESULTS: The two groups of patients showed significant differences in the tumor size, degree of tumor differentiation and lymph node metastasis (P<0.05). Cox proportional hazards model suggested that an elevated preoperative CEA level was a risk factor for survival and tumor recurrence, and increased the risks of death and tumor recurrence by 1.59 and 1.89 folds, respectively. Compared with the patients without CEA elevation, those with elevated CEA level had a significantly higher mortality rate (28.7% vs 19.8%, P<0.05) and tumor recurrence rate (32.4% vs 19.1%, P<0.05) with a significantly lower cumulative total survival rate and cumulative disease-free survival rate (P<0.05); the same results were also found in stage-III patients (P<0.05). CONCLUSIONS: New survival and recurrence data can be generated by incorporating serum CEA level in TNM staging system for more accurate prognostic assessment of the patients.

AB - OBJECTIVE: To investigate the effect of propofol on cell invasion and expressions of aquaporin-3 (APQ-3) and matrix metalloproteinase-9 (MMP-9) in human lung adenocarcinoma cancer A549 cells. METHOD: A549 cells were treated with propofol at the concentrations of 25, 50, and 100 umol/L for 12 or 24 h. RT-PCR was used to detect the effect of propofol on AQP-3 mRNA level in A549 cells, and the effects of propofol treatments for 24 h on AQP-3 and MMP-9 protein expression and the invasive ability of A549 cells were assessed with Western blotting and Transwell assay, respectively. RESULTS: Compared with the control cells, the cells treated with 25, 50, and 100 umol/L propofol showed a obvious inhibition of AQP-3 mRNA expression, with inhibition rates ranging from 0.19 to 0.65 in cells with a 12-h treatment and from 0.13 to 0.41 in cells treated for 24 h; 100 umol/L propofol treatment for 24 h produced the strongest inhibitory effect (0.13?0.035, P<0.05). AQP-3 protein expression in cells treated with 25, 50, and 100 umol/L propofol for 24 h (0.91?0.009, 0.60?0.020, and 0.57?0.006, respectively) and MMP 9 protein expression in cells treated with 50 and 100 umol/L propofol for 24 h (0.65?0.006 and 0.46?0.021, respectively) were significantly lower than those in the control cells (P<0.05). Treatment with 25, 50, and 100 umol/L propofol for 24 significantly lowered the number of invading cells (122.55?17.20, 96.33?5.82, and 74.33?2.85, respectively) compared with the control group (199.33?23.88, P<0.05). CONCLUSION: Treatment with 50 and 100 umol/L propofol inhibits cell invasion by down-regulating the expression of AQP-3 and MMP-9 in A549 cells.

AB - We treated 4 with a diagnosis of diffuse large B cell lymphoma involving the gastrointestinal tract with rituximab combined with adjusted dose EPOCH (R-DA EPOCH) scheme based on a comprehensive analysis of the onset process, clinical and pathological features, and prognosis of the patients, and evaluated their treatment response. Complete remission (CR) was achieved in 3 patients after the treatment and 1 patient with diabetes and hypertension died due to severe infection. R-DA-EPOCH regimen as the first-line treatment of gastrointestinal diffuse large B cell lymphoma has a good short-term efficacy, but its long-term efficacy awaits further evaluation in future studies with larger sample sizes. PMID- 27687668 TI - [Hemoglobin H disease with a rare alpha-thalassemia gene mutation (- SEA/alpha*92A>Galpha): pedigree analysis and genetic diagnosis]. AB - OBJECTIVE: To identify a rare alpha-thalassemia gene mutation in a family from south China and perform a pedigree analysis and genetic diagnosis of hemoglobin H (HbH) disease caused by this mutation. METHODS: Peripheral blood samples were collected from the family members for analysis of the hematological phenotype and routine test of thalassemia genes. DNA sequencing was carried out for samples that showed genotype and phenotype inconsistency. RESULTS: A rare alpha thalassemia *92A>G gene mutation was detected within this family. The proband and his sister were confirmed to have non-deletional HbH disease with alpha- SEA/alpha*92A>Galpha genotype. The proband's brother was confirmed to have an alpha-thalassemia trait with the genotype of -alpha3.7/alpha*92A>Galpha. The proband's father was identified as an alpha-thalassemia silent carrier with the genotype of alphaalpha/alpha*92A>Galpha. CONCLUSION: A rare alpha-thalassemia *92A>G gene mutation was identified for first time in south China. The description of the basic phenotypic characteristics of alpha-thalassemia trait and silent carrier caused by this mutation enriches the alpha-thalassemia gene mutation spectrum in Chinese population and helps in population screening, clinical molecular diagnosis and genetic counseling. PMID- 27687669 TI - [Clinicopathological characteristics and prognosis of uterine malignant mixed Mullerian tumor]. AB - OBJECTIVE: To evaluate the clinicopathological characteristics, treatment and prognosis of uterine malignant mixed mullerian tumor. METHODS: The clinical, pathologic and follow-up data of 16 patients with uterine malignant mixed Mullerian tumor treated in our hospital between March, 2003 and June, 2015 were analyzed. RESULTS: The 16 patients had a median age of 58 years at diagnosis, and 13 of them were postmenopausal. The number of patients with FIGO stage Ia, Ib, II, IIIa, IIIc2, and IV was 7, 3, 1, 3, 1, and 1, respectively. In 15 patients who received uterine segment diagnostic curettage, pathological examination all reported malignant results. Among the 15 patients having serum CA125 level test upon admission, 2 had elevated CA125 levels. The overall and disease-free survival rates of the 16 patients were 75% and 68.8%, respectively, and the 3 year survival rate of 13 patients who were followed up for at least 3 years was 72.7%. Two out of 12 patients receiving retroperitoneal lymph?node?dissection?had had postoperative recurrence, as compared with 3 out 4 who did not had the operation; tumor recurrence was found in 3 out of 13 patients receiving postoperative chemotherapy, as compared with 2 out of 3 patients who did not have chemotherapy; tumor recurrence occurred in 1 out of 10 patients receiving radiotherapy, as compared with 4 out of 6 patients without radiotherapy. The recurrence rates in 11 patients with FIGO stage I-II was 18.2%, and that among the 5 patients with FIGO stage III-IV was 60.0%. CONCLUSIONS: Uterine segment diagnostic curettage has a high diagnostic value for uterine malignant mixed Mullerian tumor. FIGO stage is the important prognostic factor for these patients, and early?diagnosis, accurate surgical staging, platinum-based chemotherapy and postoperative pelvic radiotherapy are all associated with a better prognosis.

AB - We report a rare case of HBsAg seroconversion after 7 years of entecavir therapy in a 48-year-old HBeAg-negative CHB male patient with chronic hepatitis B (CHB). After a poor response to a 48-week interferon-alpha 2b therapy, the patient received long-term entecavir therapy. Serum ALT levels became normal and HBV DNA viral load was undetectable at the 10th week after commencement of entecavir treatment, and seroconversion of HBsAg was detected after 7 years of entecavir therapy. PMID- 27687671 TI - Identification of small molecules that bind to the mitochondrial protein mitoNEET. AB - MitoNEET (CISD1) is a 2Fe-2S iron-sulfur cluster protein belonging to the zinc finger protein family. Recently mitoNEET has been shown to be a major role player in the mitochondrial function associated with metabolic type diseases such as obesity and cancers. The anti-diabetic drug pioglitazone and rosiglitazone were the first identified ligands to mitoNEET. Since little is known about structural requirements for ligand binding to mitoNEET, we screened a small set of compounds to gain insight into these requirements. We found that the thiazolidinedione (TZD) warhead as seen in rosiglitazone was not an absolutely necessity for binding to mitoNEET. These results will aid in the development of novel compounds that can be used to treat mitochondrial dysfunction seen in several diseases.

AB - The efficient assembly of an 18-membered macrocyclic peptide core was realized by a straightforward and convergent approach utilizing ring-closing metathesis of the corresponding linear tetrapeptides as the key transformation. This approach allowed for the facile preparation of a focused library of novel macrocycles that culminated in the discovery of a cyclophilin A inhibitor with a Kd=5.4MUM. PMID- 27687673 TI - Practical synthesis of a phthalimide-based Cereblon ligand to enable PROTAC development. AB - The use of small molecules to regulate cellular levels of specific proteins is poised to become a powerful technique in the coming years. Critical to the success of any project utilizing such an approach will be the ability to synthesize libraries of candidate small molecules for testing in cellular systems. Herein, we describe a practical synthesis of a phthalimide-based scaffold, which can be easily diversified to make Cereblon-targeting PROTACs. We demonstrate the effectiveness of this approach by synthesizing a 'PROTAC toolbox' of four amines which can be coupled to inhibitors in a straightforward manner. PMID- 27687674 TI - Targeting cytochrome P450 (CYP) 1B1 with steroid derivatives. AB - Inhibition of cytochrome P450 1B1 (CYP1B1) represents a promising therapeutic strategy, because it would enable action at three different levels: (1) by inhibiting the formation of mutagenic 4-hydroxy-estradiol, (2) by inhibiting the bioactivation of procarcinogens, and (3) by reducing drug-resistance. Surprisingly, few steroids were reported as inhibitors of CYP1B1. From a screening performed with 90 steroid derivatives, we identified thioestrone (B19) as an inhibitor (IC50=3.4MUM) of CYP1B1. Molecular modeling studies showed that the 3-SH group of B19 is closer (3.36A) to the iron atom of the heme system than the 3-OH group of enzyme substrates estrone and estradiol (4.26A and 3.58A, respectively). B19 also produced a better docking GOLD score that correlated with the inhibitory results obtained. The estrane derivative B19 represents an interesting lead compound that can be easily modified to extend the structure activity relationship study and to provide a next generation of more powerful CYP1B1 inhibitors. PMID- 27687675 TI - Detection of Infectious Pancreatic Necrosis Virus from the Leeches Hemiclepsis marginata and Hirudo medicinalis. AB - Leeches have been reported to harbor several important fish pathogens, including spring viremia of carp virus, infectious hematopoietic necrosis virus (IHNV), and viral hemorrhagic septicemia virus (VHSV), and also may contain blood protozoa. In the present study, leeches were collected from water bodies located in Kurdistan province, Iran. The specimens were tested for IHNV, VHSV, and infectious pancreatic necrosis virus (IPNV) using the PCR method. The results showed that two different species of leeches, Hemiclepsis marginata and Hirudo medicinalis, were infected by IPNV among the seven species studied. The infected leeches were found in areas that were polluted with untreated sewage coming from upstream fish farms culturing Rainbow Trout Oncorhynchus mykiss. In addition, the fish at fish farms in the vicinity had been infected with IPNV 9 months previously. Our results showed that the virus causing infectious pancreatic necrosis is present in the leeches H. marginata and H. medicinalis, suggesting that leeches are a potential source of IPNV in fish farms.

AB - PURPOSE: The aim of this observational study was to investigate the influence of continuous positive airway pressure (CPAP) on arterial blood gas and venous lactate, markers of tissue hypoxia, among obstructive sleep apnea syndrome (OSAS) patients, and determine the risk factor of serum lactate and hydrogen ion concentration (PH) in OSAS patients. MATERIALS AND METHODS: One-hundred and nine patients with newly diagnosed OSAS were enrolled in the study. All individuals were treated with CPAP for one night. Venous lactate and arterial blood gas were gathered from all subjects in the morning at the end of polysomnography and the next morning after CPAP treatment. RESULTS: Of the 109 selected subjects, the average lactate level was 2.23 +/- 0.59 mmol/L, and the mean PH, PaO2, and PaCO2 were 7.380 +/- 0.23, 88.14 +/- 17.83 mmHg, and 38.70 +/- 4.28 mmHg, respectively. Compared to baseline, lactic acid significantly decreased (2.10 +/- 0.50 mmol/L, p = 0.03), while PH increased (7.388 +/- 0.27, p < 0.05) after CPAP treatment. In addition, neck circumference and the polysomnographic parameters, including apnea hypopnea index, oxygen desaturation index (ODI), mean oxygen saturation (SpO2), and the percentage of sleep time with SpO2 <90 % (TS90 %), positively correlated with lactate, while age correlated negatively with lactate (all p < 0.05). Significantly positive associations were found between age, neck circumference, and PH; furthermore, a negative correlation was found between ODI and PH. Finally, after adjusting for confounding factors, TS90 % was the major contributing predictor for elevated lactate (p < 0.05), and age was a predictor for an increase in PH (p < 0.05). CONCLUSIONS: The results indicated that CPAP treatment could reduce serum lactate and increase PH in OSAS patients and might alleviate acid-base balance disorders in OSAS. Furthermore, TS90 % was a risk factor for elevated lactate, and age was independently associated with PH. PMID- 27687677 TI - A new alpha-pyrone from the mangrove endophytic fungus Phomopsis sp.

PMID- 27687678 TI - Comparing two lower-dose cisplatin programs for radio-chemotherapy of locally advanced head-and-neck cancers. AB - Radio-chemotherapy is a common treatment for locally advanced squamous cell head and-neck cancers (LA-SCCHN). Cisplatin (100 mg/m2) every 3 weeks is very common but associated with considerable toxicity. Therefore, cisplatin programs with lower daily doses were introduced. There is a lack of studies comparing lower dose programs. In this study, 85 patients receiving radio-chemotherapy with 20 mg/m2 cisplatin on 5 days every 4 weeks (group A) were retrospectively compared to 85 patients receiving radio-chemotherapy with 30-40 mg/m2 cisplatin weekly (group B). Groups were matched for nine factors including age, gender, performance score, tumor site, T-/N-category, surgery, hemoglobin before radio chemotherapy, and radiation technique. One- and 3-year loco-regional control rates were 83 and 69 % in group A versus 74 and 63 % in group B (p = 0.12). One- and 3-year survival rates were 93 % and 73 % in group A versus 91 and 49 % in group B (p = 0.011). On multivariate analysis, survival was significantly better for group A (HR 1.17; p = 0.002). In groups A and B, 12 and 28 % of patients, respectively, did not receive a cumulative cisplatin dose >=180 mg/m2 (p = 0.016). Toxicity rates were not significantly different. On subgroup analyses, group A patients had better loco-regional control (p = 0.040) and survival (p = 0.005) than group B patients after definitive radio-chemotherapy. In patients receiving adjuvant radio-chemotherapy, outcomes were not significantly different. Thus, 20 mg/m2 cisplatin on 5 days every 4 weeks resulted in better loco-regional control and survival in patients receiving definitive radio-chemotherapy and may be preferable for these patients. Confirmation of these results in a randomized trial is warranted. PMID- 27687679 TI - Anatomical approach to surgery for intrathoracic goiter. AB - The anatomical approach to the intrathoracic goiter (ITG) was used to understand its etiology and to rationalize surgical technique of thyroidectomy. For a retrospective chart review, we selected cases of multinodular goiter with totally ITGs (n = 69; M 29, F 40), while 916 cases with cervical goiter were used for comparison. The topography of the thyroid gland was assessed against the tracheal rings and against the vertebrae. The regional anatomy of the thoracic inlet was assessed by its bony margins and the relations of structures traversing the area. Average tracheal-diameter-to-thoracic-inlet ratio was calculated. The ITG group consisted of 52 cases of retrosternal goiter (75.4 %), nine cases of retrotracheal goiter (13 %), and eight cases of retroesophageal goiter (11.6 %). In all but one analyzed cases, the goiters were removed via cervical incision. Mean weight of goiters was 183 g. The area of thoracic inlet in the cases of ITG had no difference in comparison with the cases of cervical goiter (F/M p = 0.11/0.15), but the tracheal-diameter-to-thoracic-inlet ratio was significantly smaller (F/M p = 0.06/0.04). In the ITG cases, the position of the upper edge of the isthmus of the thyroid was about 1.5 tracheal rings lower than in healthy individuals (p = 0.03). The area of the thoracic inlet, the neck size, and the anteroposterior diameter of the inlet do not affect the development of the ITG. The smaller tracheal-diameter-to-thoracic-inlet ratio and the lower position of the thyroid gland are the main indicators for the development of the ITG. PMID- 27687680 TI - Social support and substitute voice acquisition on psychological adjustment among patients after laryngectomy. AB - The objective is to clarify whether social support and acquisition of alternative voice enhance the psychological adjustment of laryngectomized patients and which part of the psychological adjustment structure would be influenced by social support. We contacted 1445 patients enrolled in a patient association using mail surveys and 679 patients agreed to participate in the study. The survey items included age, sex, occupation, post-surgery duration, communication method, psychological adjustment (by the Nottingham Adjustment Scale Japanese Laryngectomy Version: NAS-J-L), and the formal support (by Hospital Patient Satisfaction Questionnaire-25: HPSQ-25). Social support and communication methods were added to the three-tier structural model of psychological adjustment shown in our previous study, and a covariance structure analysis was conducted. Formal/informal supports and acquisition of alternative voice influence only the "recognition of oneself as voluntary agent", the first tier of the three-tier structure of psychological adjustment. The results suggest that social support and acquisition of alternative voice may enhance the recognition of oneself as voluntary agent and promote the psychological adjustment. PMID- 27687681 TI - Comparison of escalating, constant, and reduction energy output in ESWL for renal stones: multi-arm prospective randomized study. AB - This study was designed to find out the optimized energy delivery strategy in Shock Wave Lithotripsy (SWL) that yield to the best stone-free rate (SFR). In this clinical trial, 150 consecutive patients were randomized into three groups: (a) Dose escalation, 1500 SW at 18 kV, followed by 1500 SW at 20 kV then 1500 SW at 22 kV. (b) Constant dose, 4500 SW at 20 kV. All patients undergo plain X-ray film of the urinary tract at day 1, 14, and 90 to assess stone-free rate (SFR) which was defined as no stones or painless fragments less than 4 mm. (c) Dose reduction, 1500 SW at 22 kV, followed by 1500 SW at 20 kV and then 1500 SW at 18 kV. The three treatment groups were comparable in terms of age, sex, stone size and distribution of the kidneys, and the need for Double J stent use. On day 90, the SFR achieved was 82, 90, and 84 % in the escalating, constant, and reduction energy groups, respectively. However, this rate was not statistically significant (x 2 = 1.38, p level = 0.28). At a slow rate of 60 shocks, there was no difference in stone-free rate between different voltages at 1, 14, and 90 days. Our randomized clinical trial showed no statistically significant difference in SFR between the three groups while using the slow SWL rate. Our trial is the first randomized trial comparing the three strategies. As such, a dose adjustment strategy while delivering SWL in slow rate was not recommended. PMID- 27687683 TI - Corrigendum. PMID- 27687682 TI - ADHD Symptoms in Post-Institutionalized Children Are Partially Mediated by Altered Frontal EEG Asymmetry. AB - Individual differences in the propensity for left versus right frontal electroencephalogram (EEG) asymmetry may underlie differences in approach/withdrawal tendencies and mental health deficits. Growing evidence suggests that early life adversity may shape brain development and contribute to the emergence of mental health problems. The present study examined frontal EEG asymmetry (FEA) following the transition to family care in children adopted internationally from institutional care settings between 15 and 36 months of age (N = 82; 46 female, 36 male). Two comparison groups were included: an international adoption control consisting of children adopted from foster care with little to no institutional deprivation (N = 45; 17 female, 28 male) and a post-adoption condition control consisting of children reared in birth families of the same education and income as the adoptive families (N = 48; 23 female, 25 male). Consistent with evidence of greater approach and impulsivity-related behavior problems in post-institutionalized (PI) children, PI status was associated with greater left FEA than found in the other two groups. In addition, left FEA served as a mediator between institutionalization and age 5 ADHD symptoms for girls. Age at adoption and other preadoption factors were examined with results suggesting that earlier adoption into a supportive family resulted in a more typical pattern of brain functioning. Findings support the idea that the capacity of brain activity to evidence typical functioning following perturbation may differ in relation to the timing of intervention and suggest that the earlier the intervention of adoption, the better. PMID- 27687684 TI - Novel proteasome inhibitor ixazomib sensitizes neuroblastoma cells to doxorubicin treatment. AB - Neuroblastoma (NB) is the most common extracranial malignant solid tumor seen in children and continues to lead to the death of many pediatric cancer patients. The poor outcome in high risk NB is largely attributed to the development of chemoresistant tumor cells. Doxorubicin (dox) has been widely employed as a potent anti-cancer agent in chemotherapeutic regimens; however, it also leads to chemoresistance in many cancer types including NB. Thus, developing novel small molecules that can overcome dox-induced chemoresistance is a promising strategy in cancer therapy. Here we show that the second generation proteasome inhibitor ixazomib (MLN9708) not only inhibits NB cell proliferation and induces apoptosis in vitro but also enhances dox-induced cytotoxicity in NB cells. Ixazomib inhibits dox-induced NF-kappaB activity and sensitizes NB cells to dox-induced apoptosis. More importantly, ixazomib demonstrated potent anti-tumor efficacy in vivo by enhancing dox-induced apoptosis in an orthotopic xenograft NB mouse model. Collectively, our study illustrates the anti-tumor efficacy of ixazomib in NB both alone and in combination with dox, suggesting that combination therapy including ixazomib with traditional therapeutic agents such as dox is a viable strategy that may achieve better outcomes for NB patients. PMID- 27687685 TI - Treatment of epilepsy in patients with Alzheimer's disease. AB - INTRODUCTION: Epilepsy is significantly more frequent in AD patients than in age matched controls, even though the true extent of the phenomenon is not clear yet. Areas covered: In this review, we describe in detail the available data on the pharmacological treatment of epilepsy in patients with AD. We also briefly describe general principles of AEDs use in elderly, as well as the potential cognitive profile of AEDs and safety of concomitant psychotropic drugs in patients with epilepsy and AD. Expert commentary: As some preclinical data suggest a role of epileptiform discharges in cognitive decline in AD, a prompt diagnosis and treatment of seizures in these patients should be pursued. The few data on the use of AEDs in AD patients suggest that newer AEDs (in particular lamotrigine and levetiracetam) might be good choices. Experimental data even support a potential role of some AEDs in modifying the disease course of AD. PMID- 27687686 TI - Rhythmic displays of female gibbons offer insight into the origin of dance. AB - Dance is a universal art form practiced by all human societies and has many functions including sexual attraction, social cohesion, and the therapeutic release of energy. Dance also has been reported in a small number of non-human primate species, in particular apes. However, its function has not been systematically evaluated. We observed 357 intentional, rhythmic, and nonverbal dance displays performed by four adult female cao vit gibbons (Nomascus nasutus) residing in four polygynous groups during 3000 h of observation in Bangliang, Guangxi, China. Females used dance to solicit copulations, as well as to promote a social bond with the group's lone adult male. In addition, this display appears to represent a form of non-aggressive competition among adult females living in the same group. We found that a female who had a weaker social relationship with the breeding male increased her social and sexual access to the male by an increase in dancing frequency. Given that gibbons dance in various behavioral contexts, and appears to serve several important social and sexual functions, a greater understanding of this form of gestural communication offers an instructive model for examining the origin and evolution of dance in humans and other apes.

Treatment options are limited. Herein we present successful bisphosphonate therapy in three affected patients. Patients were treated with bisphosphonates (either pamidronate or zoledronate) for different time periods. The following outcome variables were assessed: skeletal pain, range of motion, bone densitometry, internal medical problems as well as neurocognitive function. Skeletal pain was dramatically reduced in all patients soon after initiation of therapy and bone mineral density increased. Range of motion did not significantly improve. One patient is still able to walk with aids at the age of 14 years. Neurocognitive development was normal in all patients. Bisphosphonate therapy was effective especially in controlling skeletal pain in MONA spectrum disorder. Early initiation of treatment seems to be particularly important in order to achieve the best possible outcome.

AB - The common behaviour of a wave is determined by wave parameters of its medium, which are generally associated with the characteristic oscillations of its corresponding elementary particles. In the context of metamaterials, the decoupled excitation of these fundamental oscillations would provide an ideal platform for top-down and reconfigurable access to the entire constitutive parameter space; however, this has remained as a conceivable problem that must be accomplished, after being pointed out by Pendry. Here by focusing on acoustic metamaterials, we achieve the decoupling of density rho, modulus B-1 and bianisotropy xi, by separating the paths of particle momentum to conform to the characteristic oscillations of each macroscopic wave parameter. Independent access to all octants of wave parameter space (rho, B-1, xi)=(+/-,+/-,+/-) is thus realized using a single platform that we call an omni meta-atom; as a building block that achieves top-down access to the target properties of metamaterials. PMID- 27687690 TI - SAMSA: a comprehensive metatranscriptome analysis pipeline. AB - BACKGROUND: Although metatranscriptomics-the study of diverse microbial population activity based on RNA-seq data-is rapidly growing in popularity, there are limited options for biologists to analyze this type of data. Current approaches for processing metatranscriptomes rely on restricted databases and a dedicated computing cluster, or metagenome-based approaches that have not been fully evaluated for processing metatranscriptomic datasets. We created a new bioinformatics pipeline, designed specifically for metatranscriptome dataset analysis, which runs in conjunction with Metagenome-RAST (MG-RAST) servers. Designed for use by researchers with relatively little bioinformatics experience, SAMSA offers a breakdown of metatranscriptome transcription activity levels by organism or transcript function, and is fully open source. We used this new tool to evaluate best practices for sequencing stool metatranscriptomes. RESULTS: Working with the MG-RAST annotation server, we constructed the Simple Annotation of Metatranscriptomes by Sequence Analysis (SAMSA) software package, a complete pipeline for the analysis of gut microbiome data. SAMSA can summarize and evaluate raw annotation results, identifying abundant species and significant functional differences between metatranscriptomes. Using pilot data and simulated subsets, we determined experimental requirements for fecal gut metatranscriptomes. Sequences need to be either long reads (longer than 100 bp) or joined paired-end reads. Each sample needs 40-50 million raw sequences, which can be expected to yield the 5-10 million annotated reads necessary for accurate abundance measures. We also demonstrated that ribosomal RNA depletion does not equally deplete ribosomes from all species within a sample, and remaining rRNA sequences should be discarded. Using publicly available metatranscriptome data in which rRNA was not depleted, we were able to demonstrate that overall organism transcriptional activity can be measured using mRNA counts. We were also able to detect significant differences between control and experimental groups in both organism transcriptional activity and specific cellular functions. CONCLUSIONS: By making this new pipeline publicly available, we have created a powerful new tool for metatranscriptomics research, offering a new method for greater insight into the activity of diverse microbial communities. We further recommend that stool metatranscriptomes be ribodepleted and sequenced in a 100 bp paired end format with a minimum of 40 million reads per sample.

AB - Alzheimer's disease (AD) is the most prevalent form of dementia characterized by the extracellular accumulation of amyloid beta (Abeta) peptides, which are produced by proteolytic cleavages of amyloid precursor protein (APP). Gangliosides are involved in AD pathophysiology including Abeta deposition and APP processing, yet the detailed mechanisms are not fully understood. Here we examined how changes in the carbohydrate moiety of gangliosides alter APP processing in human melanoma cells, neuroectoderm-derived cells. We showed that forced expression of GD2, GM2 or GM1 (by introducing B4GALNT1 cDNA into cells not expressing this glycosyltransferase) results in increases of alpha- and beta-site cleavages of APP with a prominent increase in beta-cleavage. We also showed that beta-site APP cleaving enzyme 1 (BACE1) protein is highly protected from the degradation in cells expressing these gangliosides, thereby increasing the expression of this protein. Unexpectedly, adding gangliosides exogenously altered neither BACE1 levels nor beta-site cleavage. The stabilisation of BACE1 protein led to the increase of this protein in lipid rafts, where BACE1 processes APP. Based on the current results, we propose a hitherto undisclosed link between ganglioside expression and AD; the expression of B4GALNT1 positively regulates the beta-site cleavage by mainly inhibiting the lysosomal degradation of BACE1 protein. PMID- 27687692 TI - T-cell subsets in lymph nodes identify a subgroup of follicular lymphoma patients with favorable outcome. AB - We have analyzed in lymph nodes at diagnosis of 75 patients with follicular lymphoma (FL) the relationship between different T-cell subpopulations, assessed by immunohistochemistry (IHC) and flow cytometry (FC), with the outcome. CD4+ cells were the most abundant T-cells in tumor tissue sections, whilst CD57+ cells were the less frequent. In addition to nonambulatory performance status, advanced stage and FLIPI, low CD4+CD57+/CD4+ ratio (p = .041), and low CD4+/CD8+ ratio (p = .008) predicted poor overall survival (OS). Multivariate analysis showed that CD4+CD57+/CD4+ ratio was the most important variable for OS. In conclusion, T cell subpopulations, including CD4+CD57+/CD4+ ratio analyzed by FC, could identify FL patients with favorable outcome.

AB - Water is characterized by large molecular electric dipole moments and strong interactions between molecules; however, hydrogen bonds screen the dipole-dipole coupling and suppress the ferroelectric order. The situation changes drastically when water is confined: in this case ordering of the molecular dipoles has been predicted, but never unambiguously detected experimentally. In the present study we place separate H2O molecules in the structural channels of a beryl single crystal so that they are located far enough to prevent hydrogen bonding, but close enough to keep the dipole-dipole interaction, resulting in incipient ferroelectricity in the water molecular subsystem. We observe a ferroelectric soft mode that causes Curie-Weiss behaviour of the static permittivity, which saturates below 10 K due to quantum fluctuations. The ferroelectricity of water molecules may play a key role in the functioning of biological systems and find applications in fuel and memory cells, light emitters and other nanoscale electronic devices. PMID- 27687695 TI - Canthaxanthin: From molecule to function. AB - The aim of this review is to summarize the relevant literature about the use of canthaxanthin in food science and nutrition research. Canthaxanthin is a red orange carotenoid that belongs to the xanthophyll group. This naturally occurring pigment is present in bacteria, algae and some fungi. Canthaxanthin is also responsible for the color of flamingo feathers, koi carp skin and crustacean shells. Canthaxanthin is widely used in poultry (broiler, laying hens) as a feed additive. Canthaxanthin can be obtained by total synthesis. The canthaxanthin mediated color of foods is an important quality criterion for consumers. Recently, the potential health-promoting effects of canthaxanthin have been discussed. Canthaxanthin enrichment of LDL has the potential to protect cholesterol from oxidation. In addition to its free radical scavenging and antioxidant properties (e.g., the induction of catalase and superoxide dismutase), canthaxanthin's immunomodulatory activity (e.g., enhancing the proliferation and function of immune competent cells) and its important role in gap junction communication (e.g., induction of the transmembrane protein connexin 43) have been reported. Many studies regarding the potential health benefits of canthaxanthin have been conducted in vitro and should be validated in appropriate in vivo models. PMID- 27687696 TI - Efficient and Tunable Three-Dimensional Functionalization of Fully Zwitterionic Antifouling Surface Coatings. AB - To enhance the sensitivity and selectivity of surface-based (bio)sensors, it is of crucial importance to diminish background signals that arise from the nonspecific binding of biomolecules, so-called biofouling. Zwitterionic polymer brushes have been shown to be excellent antifouling materials. However, for sensing purposes, antifouling does not suffice but needs to be combined with the possibility to efficiently modify the brush with recognition units. So far this has been achieved only at the expense of either antifouling properties or binding capacity. Herein we present a conceptually new approach by integrating both characteristics into a single tailor-made monomer: a novel sulfobetaine-based zwitterionic monomer equipped with a clickable azide moiety. Copolymerization of this monomer with a well-established standard sulfobetaine monomer results in highly antifouling surface coatings with a large yet tunable number of clickable groups present throughout the entire brush. Subsequent functionalization of the azido brushes via widely used strain-promoted alkyne azide click reactions yields fully zwitterionic 3D-functionalized coatings with a recognition unit of choice that can be tailored for any specific application. Here we show a proof of principle with biotin-functionalized brushes on Si3N4 that combine excellent antifouling properties with specific avidin binding from a protein mixture. The signal-to-noise ratio is significantly improved over that of traditional chain end modification of sulfobetaine polymer brushes, even if the azide content is lowered to 1%. This therefore offers a viable approach to the development of biosensors with greatly enhanced performance on any surface. PMID- 27687697 TI - Widespread DNA hypomethylation and differential gene expression in Turner syndrome. AB - Adults with 45,X monosomy (Turner syndrome) reflect a surviving minority since more than 99% of fetuses with 45,X monosomy die in utero. In adulthood 45,X monosomy is associated with increased morbidity and mortality, although strikingly heterogeneous with some individuals left untouched while others suffer from cardiovascular disease, autoimmune disease and infertility. The present study investigates the leukocyte DNAmethylation profile by using the 450K Illumina Infinium assay and the leukocyte RNA-expression profile in 45,X monosomy compared with karyotypically normal female and male controls. We present results illustrating that genome wide X-chromosome RNA-expression profile, autosomal DNA methylation profile, and the X-chromosome methylation profile clearly distinguish Turner syndrome from controls. Our results reveal genome wide hypomethylation with most differentially methylated positions showing a medium level of methylation. Contrary to previous studies, applying a single loci specific analysis at well-defined DNA loci, our results indicate that the hypomethylation extend to repetitive elements. We describe novel candidate genes that could be involved in comorbidity in TS and explain congenital urinary malformations (PRKX), premature ovarian failure (KDM6A), and aortic aneurysm formation (ZFYVE9 and TIMP1). PMID- 27687698 TI - Evaluation of intraosseous sampling for measurements of alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, creatinine kinase, gamma glutamyl transferase and lactate dehydrogenase. AB - BACKGROUND: Intraosseous (IO) access can be established faster than a venous or arterial access when there is an urgent need for rapid initiation of treatment. The access can also be used to draw marrow samples. The aim of the present study was to evaluate the potential use of IO samples for enzyme determinations using a porcine model. MATERIALS AND METHODS: Bilateral tibial intraosseous cannulae and an arterial catheter were used for blood sampling from five healthy anesthetized pigs. Samples were collected at baseline and thereafter hourly for 6 h and analyzed for alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, creatinine kinase, gamma-glutamyl transferase and lactate dehydrogenase. RESULTS: Creatinine kinase, lactate dehydrogenase and alkaline phosphatase levels decreased over time. The differences between IO and arterial sampling were limited for all studied markers. CONCLUSION: The correlation between marrow and blood analysis for liver function tests and CK is sufficiently accurate in an emergency situation. PMID- 27687699 TI - The Effect of Aluminum Exposure on Reproductive Ability in the Bank Vole (Myodes glareolus). AB - Human impact on the environment is steadily increasing the amounts of aluminum in the ecosystems. This element accumulates in plants and water, potentially exposing herbivores to its harmful effect. In heavily polluted sites, a decrease in the density of small rodent populations has been observed. This decline may be caused by many factors, including decreased fertility. The aim of the presented research was to determine how aluminum, administered at concentrations similar to those recorded in industrial districts (Al I = 3 mg/l, Al II = 200 mg/l), affects the reproductive abilities of small rodents. As the indicators of reproductive abilities, body weight, weight of the testes and accessory sex glands of males, and uterus weight of females were estimated. In females, the number of matured follicles (types 6, 7, and 8) was analyzed, while in males, the quantity and quality (matured, viable, swollen, motile, head abnormalities) of epididymal sperm cells were assessed. Moreover, the development of testes, measured by spermatogenic index, was determined. The model species was the bank vole. Our results have proven that aluminum impairs adult individuals' reproductive abilities by decreasing the quality and quantity of sperm cells and by causing morphologically abnormal development of the gonads. However, no difference in male organometric parameters was found, and only in females treated with 3 mg/l Al, the uterus weight was higher than control. No differences were found in the total number of matured follicles. These results suggest that the decline in rodent numbers in industrial districts is due, at least in part, to poorer males' reproductive abilities, resulting from exposure to aluminum contamination. PMID- 27687700 TI - Determine Multiple Elements Simultaneously in the Sera of Umbilical Cord Blood Samples-a Very Simple Method. AB - Analyzing the concentrations of heavy metals in the sera of umbilical cord blood samples can provide useful information about prenatal exposure to environmental agents. An analytical method based on ICP-MS to simultaneously determine multiple elements in umbilical cord blood samples was developed for assessing the in utero exposure to metallic and metalloid elements. The method only required as little as 100 MUL of serum diluted 1:25 for direct analysis. Matrix-matched protocol was used to eliminate mass matrix interference and kinetic energy discrimination mode was used to eliminate the polyatomic ion interference. The assay was completed on average within 4 min with the detection limits ranging from 0.0002 to 44.4 MUg/L for all the targeted elements. The detection rates for most of elements were 100 % other than cadmium (Cd), lead (Pb), and mercury (Hg). The testing results of the certified reference materials were ideal. The method is simple and sensitive, so it is suitable for the monitoring of large quantities of samples. PMID- 27687701 TI - Aberrant iron metabolism might have an impact on progression of diseases in Tsumura Suzuki obese diabetes mice, a model of spontaneous metabolic syndrome. AB - Tsumura Suzuki obese diabetes (TSOD) mice spontaneously develop obesity and type 2 diabetes with aberrant accumulation of excessive iron in the spleen. Aberrantly accumulated iron may cause oxidative stress and result in various symptoms of metabolic syndrome in the mice. We investigated iron metabolism and oxidative stress in TSOD mice. Male TSOD and control mice were killed at 2, 3, 6, and 8 months of age, and blood and tissue samples were collected. The serum levels of ferritin and oxidized low-density lipoprotein (OxLDL) were measured. Total glutathione concentrations of liver and spleen were also measured. Serum ferritin and OxLDL were higher in TSOD mice than in control mice at 2 and 6 months. In addition, the glutathione concentrations in TSOD mice were lower in the liver and higher in the spleen at 3 and 6 months than those in control mice. These results suggest that abnormal iron metabolism and imbalanced oxidative stress occurs in young and old TSOD mice. We propose herein that TSOD mice might be a unique and valuable model for investigating the role of iron metabolism in pathogenesis of metabolic syndrome.

AB - We present a case of an adult with metastatic carcinoid heart disease, in whom live/real time three-dimensional transthoracic echocardiography provided incremental value over two-dimensional transthoracic echocardiography in assessing involvement of the aortic valve. PMID- 27687703 TI - Negative beliefs about low back pain are associated with persistent high intensity low back pain. AB - While previous cross-sectional studies have found that negative beliefs about low back pain are associated with pain intensity, the relationship between back beliefs and persistent low back pain is not well understood. This cohort study aimed to examine the role of back beliefs in persistent low back pain in community-based individuals. A hundred and ninety-two participants from a previous musculoskeletal health study were invited to take part in a two-year follow-up study. Beliefs about back pain were assessed by the Back Beliefs Questionnaire (BBQ) at baseline and low back pain intensity was measured by the Chronic Pain Grade Questionnaire at baseline and follow-up. Of the 150 respondents (78.1%), 16 (10.7%) reported persistent high intensity low back pain, 12 (8.0%) developed high intensity low back pain, in 16 (10.7%) their high intensity low back pain resolved and 106 (70.7%) experienced no high intensity low back pain. While participants were generally positive about low back pain (BBQ mean (SD) = 30.2 (6.4)), those with persistent high intensity pain reported greater negativity (BBQ mean (SD) = 22.6 (4.9)). Negative beliefs about back pain were associated with persistent high intensity low back pain after adjusting for confounders (M (SE) = 23.5 (1.6) vs. >30.1 (1.7), p < .001). This study found negative back beliefs were associated with persistent high intensity low back pain over 2 years in community-based individuals. While further longitudinal studies are required, these findings suggest that targeting beliefs in programs designed to treat and prevent persistent high intensity low back pain may be important. PMID- 27687704 TI - In situ DART-MS as a Versatile and Rapid Dereplication Tool in Lichenology: Chemical Fingerprinting of Ophioparma ventosa. AB - INTRODUCTION: Lichens widely occur all over the world and are known to produce unique secondary metabolites with various biological activities. OBJECTIVE: To develop high-throughput screening approaches requiring little to no sample preparation to alleviate the dereplication holdup and accelerate the discovery workflow of new structures from lichens. METHODOLOGY: The extracellular distribution of lichen metabolites is incentive for in situ chemical profiling of lichens using the ambient mass spectrometry DART-MS. For this purpose, the chlorolichen Ophioparma ventosa, producing an array of lichen polyphenolics that encompass the main structural classes associated to lichen chemodiversity, represented a relevant model to assess the versatility of this platform. The feasibility of this approach was first established by analysing the pure compounds known from this species prior to being extended to different solid organs of the lichen. RESULTS: All tested compounds could be detected in positive and negative ion modes, most often with prevalent protonated or deprotonated molecules. Only depsides underwent a significant in-source fragmentation in both ionisation modes, which should be regarded as an added value for their structural elucidation. In situ DART-MS analyses of Ophioparma ventosa provided an extensive chemical profile and noteworthy pinpointed miriquidic acid, an unusual lichen depside so far unknown within this species. At last, in situ DART-MS granted a first insight into the distribution of the metabolites within the lichen. CONCLUSION: DART-MS represents a versatile tool to the wide field of lichenology, facilitating accelerated and sharp analyses of lichens and bypassing costly and tedious procedures of solvent extraction.

AB - We report the characterization of kisspeptin gene which is considered to be essential for successful animal reproduction. The full-length cDNA sequence of kiss2 was 583 bp, consisted of 11 bp 5'-UTR (untranslated region) and 194 bp 3' UTR, respectively. Open reading frame of 378 bp encoding a putative protein of 125 amino acids. The Catla catla kiss2 protein was having a molecular weight of 14.51 kDa and isoelectric point (pI) of 8.46. There were four serine (Ser), four threonine (Thr) and two tyrosine (Tyr) phosphorylation sites and no N glycosylation sites on the predicted protein. The amino acids on positions 8, 11, 24, 80 and 114 were detected to be ligand binding sites. The signal peptide analysis predicted that C. catla kiss2 is a secretory protein. Kiss2 protein is localized in nuclear region (49.7%) and the extracellular region (38.3%) of the cell. Analysis of tissue distribution revealed that, kiss2 transcripts were predominantly expressed in the brain and gonads, with expression levels in female higher than those of male. Ontogenetic analysis of kiss2 demonstrated that expression level was low during early phase of development stages and more expression was observed during mature stage. Overall present results lay a strong basis for understanding the role of kisspeptin in the neuroendocrine system in teleosts. PMID- 27687707 TI - Preparation, characterization, and pharmacokinetics of tilmicosin- and florfenicol-loaded hydrogenated castor oil-solid lipid nanoparticles. AB - To effectively control bovine mastitis, tilmicosin (TIL)- and florfenicol (FF) loaded solid lipid nanoparticles (SLN) with hydrogenated castor oil (HCO) were prepared by a hot homogenization and ultrasonication method. In vitro antibacterial activity, properties, and pharmacokinetics of the TIL-FF-SLN were studied. The results demonstrated that TIL and FF had a synergistic or additive antibacterial activity against Streptococcus dysgalactiae, Streptococcus uberis, and Streptococcus agalactiae. The size, polydispersity index, and zeta potential of nanoparticles were 289.1 +/- 13.7 nm, 0.31 +/- 0.05, and -26.7 +/- 1.3 mV, respectively. The encapsulation efficiencies for TIL and FF were 62.3 +/- 5.9% and 85.1 +/- 5.2%, and the loading capacities for TIL and FF were 8.2 +/- 0.6% and 3.3 +/- 0.2%, respectively. The TIL-FF-SLN showed no irritation in the injection site and sustained release in vitro. After medication, TIL and FF could maintain about 0.1 MUg/mL for 122 and 6 h. Compared to the control solution, the SLN increased the area under the concentration-time curve (AUC0-t ), elimination half-life (T1/2ke ), and mean residence time (MRT) of TIL by 33.09-, 23.29-, and 37.53-fold, and 1.69-, 5.00-, and 3.83-fold for FF, respectively. These results of this exploratory study suggest that the HCO-SLN could be a useful system for the delivery of TIL and FF for bovine mastitis therapy. PMID- 27687706 TI - Ketamine-induced inhibition of glycogen synthase kinase-3 contributes to the augmentation of alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptor signaling. AB - OBJECTIVES: Sub-anesthetic doses of ketamine have been found to provide rapid antidepressant actions, indicating that the cellular signaling systems targeted by ketamine are potential sites for therapeutic intervention. Ketamine acts as an antagonist of N-methyl-D-aspartate (NMDA) receptors, and animal studies indicate that subsequent augmentation of signaling by alpha-amino-3-hydroxy-5 methylisoxazole-4-propionic acid (AMPA) receptors is critical for the antidepressant outcome. METHODS: In this study, we tested if the inhibitory effect of ketamine on glycogen synthase kinase-3 (GSK3) affected hippocampal cell surface AMPA receptors using immunoblotting of membrane and synaptosomal extracts from wild-type and GSK3 knockin mice. RESULTS: Treatment with an antidepressant dose of ketamine increased the hippocampal membrane level of the AMPA glutamate receptor (GluA)1 subunit, but did not alter the localization of GluA2, GluA3, or GluA4. This effect of ketamine was abrogated in GSK3 knockin mice expressing mutant GSK3 that cannot be inhibited by ketamine, demonstrating that ketamine induced inhibition of GSK3 is necessary for up-regulation of cell surface AMPA GluA1 subunits. AMPA receptor trafficking is regulated by post-synaptic density 95 (PSD-95), a substrate for GSK3. Ketamine treatment decreased the hippocampal membrane level of phosphorylated PSD-95 on Thr-19, the target of GSK3 that promotes AMPA receptor internalization. CONCLUSIONS: These results demonstrate that ketamine-induced inhibition of GSK3 causes reduced phosphorylation of PSD 95, diminishing the internalization of AMPA GluA1 subunits to allow for augmented signaling through AMPA receptors following ketamine treatment. PMID- 27687710 TI - Junior doctors say what BMA should do now to stop the new contract. PMID- 27687709 TI - Performance validity in undergraduate research participants: a comparison of failure rates across tests and cutoffs. AB - OBJECTIVE: This study compared failure rates on performance validity tests (PVTs) across liberal and conservative cutoffs in a sample of undergraduate students participating in academic research. METHOD: Participants (n = 120) were administered four free-standing PVTs (Test of Memory Malingering, Word Memory Test, Rey 15-Item Test, Hiscock Forced-Choice Procedure) and three embedded PVTs (Digit Span, letter and category fluency). Participants also reported their perceived level of effort during testing. RESULTS: At liberal cutoffs, 36.7% of the sample failed >=1 PVTs, 6.7% failed >=2, and .8% failed 3. At conservative cutoffs, 18.3% of the sample failed >=1 PVTs, 2.5% failed >=2, and .8% failed 3. Participants were 3 to 5 times more likely to fail embedded (15.8-30.8%) compared to free-standing PVTs (3.3-10.0%). There was no significant difference in failure rates between native and non-native English speaking participants at either liberal or conservative cutoffs. Additionally, there was no relation between self reported effort and PVT failure rates. CONCLUSIONS: Although PVT failure rates varied as a function of PVTs and cutoffs, between a third and a fifth of the sample failed >=1 PVTs, consistent with high initial estimates of invalid performance in this population. Embedded PVTs had notably higher failure rates than free-standing PVTs. Assuming optimal effort in research using students as participants without a formal assessment of performance validity introduces a potentially significant confound in the study design. PMID- 27687711 TI - Of making many books there is no end: the development of the developmental literature. PMID- 27687708 TI - Multi-perspective quality control of Illumina RNA sequencing data analysis. AB - Quality control (QC) is a critical step in RNA sequencing (RNA-seq). Yet, it is often ignored or conducted on a limited basis. Here, we present a multi perspective strategy for QC of RNA-seq experiments. The QC of RNA-seq can be divided into four related stages: (1) RNA quality, (2) raw read data (FASTQ), (3) alignment and (4) gene expression. We illustrate the importance of conducting QC at each stage of an RNA-seq experiment and demonstrate our recommended RNA-seq QC strategy. Furthermore, we discuss the major and often neglected quality issues associated with the three major types of RNA-seq: mRNA, total RNA and small RNA. This RNA-seq QC overview provides comprehensive guidance for researchers who conduct RNA-seq experiments. PMID- 27687712 TI - Functional outcome in 17 patients whose mandibles were reconstructed with free fibular flaps. AB - OBJECTIVE: The vascularised free fibular flap is considered to be a reliable choice for reconstruction of oromandibular defects, especially after resection of malignant tumours in the area. This study evaluates the functional outcome of this method. METHOD: From January 2001 - May 2014, 37 patients were treated at the University Hospital of Linkoping using the free fibular flap. The authors present the results from 17. This study reviewed their records and used the University of Washington Quality-of-Life questionnaire (UW-QoL), the Head and Neck Performance Status Scale (PSS), and interviews to assess their outcome. RESULTS AND CONCLUSIONS: Functional evaluation showed a significant decrease in chewing (16 out of 17 patients), appearance (n = 10), salivation (n = 6), sensitivity in the mouth and skin (n = 16), occlusive problems in the mouth (n = 13), and range of mouth opening (n = 12). The remaining domains showed acceptable results, although most of them probably could not compare with the preoperative function. Out of 17 patients, six had to adjust their eating in public significantly, three thought their activity to be considerably restricted and two their recreation to be notably diminished. Common postoperative complications were infections or fistula in the mandible (n = 6), partial or complete rejection of the cutaneous flap (n = 4), and rupture of some of the sutures (n = 3). Nine patients required at least one more operation to repair defects, and six required a new soft tissue flap. PMID- 27687714 TI - Comparison of post-authorisation measures from regulatory authorities with additional evidence requirements from the HTA body in Germany - are additional data requirements by the Federal Joint Committee justified? AB - OBJECTIVES: The aim of this study was to compare post-authorisation measures (PAMs) from the European Medicines Agency (EMA) with data requests in fixed termed conditional appraisals of early benefit assessments from the German Federal Joint Committee (G-BA). METHODS: Medicinal products with completed benefit assessments during an assessment period of 3.5 years were considered. PAMs extracted from European Public Assessment Reports (EPARs) were compared with data requests issued by the G-BA in the context of conditional appraisals. RESULTS: Twenty conditional appraisals (19 products) and 34 EPARs containing PAMs (33 products) were identified. Data categories (efficacy, safety, etc.), data types (type of study required to address the request) and clarity of requests were determined. Conditional appraisals disproportionately focused on oncology products (13/19 products with conditional appraisals vs. 14/33 products with PAMs). No clear rationale for the G-BA issuing conditional appraisals could be identified in public sources. Both EMA and G-BA requested mainly efficacy and safety data (44/54 and 23/35 categories requested, respectively); however, 28/35 G-BA data requirements went beyond requests made by the EMA. Almost half of the G BA requests (9/20), but no PAMs, were unclear, and no methodological guidance for fulfilling the data requirements was provided by the G-BA. CONCLUSIONS: Better alignment between data requests from regulatory authorities and health technology assessment bodies is strongly recommended. PMID- 27687715 TI - Voxel-wise grey matter asymmetry analysis in left- and right-handers. AB - Handedness is thought to originate in the brain, but identifying its structural correlates in the cortex has yielded surprisingly incoherent results. One idea proclaimed by several authors is that structural grey matter asymmetries might underlie handedness. While some authors have found significant associations with handedness in different brain areas (e.g. in the central sulcus and precentral sulcus), others have failed to identify such associations. One method used by many researchers to determine structural grey matter asymmetries is voxel based morphometry (VBM). However, it has recently been suggested that the standard VBM protocol might not be ideal to assess structural grey matter asymmetries, as it establishes accurate voxel-wise correspondence across individuals but not across both hemispheres. This could potentially lead to biased and incoherent results. Recently, a new toolbox specifically geared at assessing structural asymmetries and involving accurate voxel-wise correspondence across hemispheres has been published [F. Kurth, C. Gaser, E. Luders. A 12-step user guide for analyzing voxel-wise gray matter asymmetries in statistical parametric mapping (SPM), Nat Protoc 10 (2015), 293-304]. Here, we used this new toolbox to re-assess grey matter asymmetry differences in left- vs. right-handers and linked them to quantitative measures of hand preference and hand skill. While we identified several significant left-right asymmetries in the overall sample, no difference between left- and right-handers reached significance after correction for multiple comparisons. These findings indicate that the structural brain correlates of handedness are unlikely to be rooted in macroscopic grey matter area differences that can be assessed with VBM. Future studies should focus on other potential structural correlates of handedness, e.g. structural white matter asymmetries.

AB - BACKGROUND: Patients with lower extremity peripheral artery disease (PAD) have decreased mobility, which is not fully explained by impaired blood supply to the lower limb. Additionally, reports are conflicted regarding fiber type distribution patterns in PAD, but agree that skeletal muscle mitochondrial respiration is impaired. METHODS: To test the hypothesis that reduced muscle fiber oxidative activity and type I distribution are negatively associated with walking performance in PAD, calf muscle biopsies from non-PAD (n = 7) and PAD participants (n = 26) were analyzed immunohistochemically for fiber type and size, oxidative activity, markers of autophagy, and capillary density. Data were analyzed using analysis of covariance. RESULTS: There was a wide range in fiber type distribution among subjects with PAD (9-81 % type I fibers) that did not correlate with walking performance. However, mean type I fiber size correlated with 4-min normal- and fastest-paced walk velocity (r = 0.4940, P = 0.010 and r = 0.4944, P = 0.010, respectively). Although intensity of succinate dehydrogenase activity staining was consistent with fiber type, up to 17 % of oxidative fibers were devoid of mitochondria in their cores, and the core showed accumulation of the autophagic marker, LC3, which did not completely co-localize with LAMP2, a lysosome marker. CONCLUSIONS: Calf muscle type I fiber size positively correlates with walking performance in PAD. Accumulation of LC3 and a lack of co localization of LC3 with LAMP2 in the area depleted of mitochondria in PAD fibers suggests impaired clearance of damaged mitochondria, which may contribute to reduced muscle oxidative capacity. Further study is needed to determine whether defective mitophagy is associated with decline in function over time, and whether interventions aimed at preserving mitochondrial function and improving autophagy can improve walking performance in PAD.

AB - Nitric oxide (NO) possibly plays an important role in the events resulting in hyperalgesia. NO synthase (NOS) is a key enzyme in the production of NO. Changes in NOS expression in primary sensory neurons may be involved in the persistent sensory abnormalities that can be induced by inflammation. To assess the possible roles of NOS in trigeminal sensory system, we studied changes in the expression of NOS isoforms in the trigeminal ganglion (TG) following chronic inflammation after pulp exposure (PX) in rats. The neurons innervating injured tooth in the TG were labeled by fluoro-gold (FG). Immunohistochemical staining was used to reveal the presence of NOS. The results showed that within the FG-labeled population, neuron counts revealed a significant increase in the proportion of NOS neurons following PX, in which the frequency of iNOS and nNOS-positive neurons started to increase at 3 and 7day, respectively, and peaked at 28day. There was no eNOS expression observed in the control group and PX-treated groups. The results demonstrate that PX-induced chronic pulpal inflammation results in significant increase of nNOS and iNOS in the TG. It suggests that nNOS and iNOS could be involved in mediation of peripheral processing of nociceptive information following chronic tooth pulp inflammation.

AB - DNAJC6 has been reported as a causative gene for early onset Parkinson's disease (EOPD) in some populations, and different mutations have been reported to be associated with EOPD. However, Until now, there is limited information about DNAJC6 gene test in sporadic EOPD patients in Chinese population. Herein, we performed comprehensive DNAJC6 mutation screenings in 117 EOPD patients from Chinese population. None of the reported disease-causing mutations were found. However, we identified a novel non-synonymous heterozygous variant c.2798T>C (p.Val933Ala). Bioinformatics analysis demonstrate that the c.2798T>C variant exhibits highly conserved residues across species. Our data suggests that DNAJC6 mutations are not common causes of EOPD in Chinese population. PMID- 27687718 TI - Epigenetic legacy of parental experiences: Dynamic and interactive pathways to inheritance. AB - The quality of the environment experienced by an individual across his or her lifespan can result in a unique developmental trajectory with consequences for adult phenotype and reproductive success. However, it is also evident that these experiences can impact the development of offspring with continued effect on subsequent generations. Epigenetic mechanisms have been proposed as a mediator of both these within- and across-generation effects, and there is increasing evidence to support the role of environmentally induced changes in DNA methylation, posttranslational histone modifications, and noncoding RNAs in predicting these outcomes. Advances in our understanding of these molecular modifications contribute to increasingly nuanced perspectives on plasticity and transmission of phenotypes across generations. A challenge that emerges from this research is in how we integrate these "new" perspectives with traditional views of development, reproduction, and inheritance. This paper will highlight evidence suggestive of an epigenetic impact of the environment on mothers, fathers, and their offspring, and illustrate the importance of considering the dynamic nature of reproduction and development and inclusive views of inheritance within the evolving field of behavioral and environmental epigenetics. PMID- 27687719 TI - The role of p38MAPK activation in spinal dorsal horn in remifentanil-induced postoperative hyperalgesia in rats. AB - OBJECTIVES: Remifentanil may induce hyperalgesia. Recent studies implicate a close relationship between post-surgical hyperalgesia and phosphorylation and activation of p38 mitogen-activated protein kinase (p38MAPK) in the spinal microglia. This study aimed to investigate whether the combination of post surgical and remifentanil-induced hyperalgesia worsens post-operative pain and whether phosphorylated p38MAPK (phospho-p38MAPK) in the spinal dorsal horn in rats is involved in remifentanil-induced postoperative hyperalgesia. METHODS: Sprague-Dawley rats were randomly divided into six groups: control, incision only, remifentanil only, remifentanil + incision, remifentanil + incision + SB203580, and remifentanil + incision + DMSO. The p38MAPK inhibitor SB203580 and DMSO were injected intrathecally. A right plantar surgical incision was performed in the incision groups, and remifentanil was infused for 60 min in the remifentanil groups. Mechanical paw withdrawal threshold (PWT) and thermal paw withdrawal latency (PWL) of the bilateral hind paws were measured and the number of phospho-p38MAPK-positive cells in rat spinal dorsal horn sections was counted. RESULTS: Intravenous remifentanil infusion decreased bilateral plantar PWL values from 1 h to 3 days after surgery, however there was no additive effect with incision-induced values. There was a significant increase in the number of dorsal horn phospho-p38MAPK-positive cells in the remifentanil + incision group compared to the incision group, but no increase in the number of these cells when remifentanil was given alone. Intrathecal pretreatment with SB203580 attenuated remifentanil + incision-induced postoperative hyperalgesia and significantly reduced activation of phospho-p38MAPK in spinal dorsal horn. CONCLUSIONS: Incision-induced and remifentanil-induced increases in hyperalgesia were not additive when incision and remifentanil were used together. Data on phospho 38MAPK activation in remifenanil-induced hyperalgesia were contradictory and need further clarification. PMID- 27687720 TI - Prevention of Critical Care Complications in the Coronary Intensive Care Unit: Protocols, Bundles, and Insights From Intensive Care Studies. AB - Over the past half century, coronary care units have expanded from specialized ischemia arrhythmia monitoring units into intensive care units (ICUs) for acutely ill and medically complex patients with a primary cardiac diagnosis. Patients admitted to contemporary coronary intensive care units (CICUs) are at risk for common and preventable critical care complications, yet many CICUs have not adopted standard-of-care prevention protocols and practices from general ICUs. In this article, we (1) review evidence-based interventions and care bundles that reduce the incidence of ventilator-associated pneumonia, excess sedation during mechanical ventilation, central line infections, stress ulcers, malnutrition, delirium, and medication errors and (2) recommend pragmatic adaptations for common conditions in critically ill patients with cardiac disease, and (3) provide example order sets and practical CICU protocol implementation strategies.

PMID- 27687722 TI - Evaluation of the effects and adverse drug reactions of low-dose dexamethasone premedication with weekly docetaxel. AB - PURPOSE: A weekly docetaxel regimen had comparable efficacy with a tri-weekly schedule and caused significantly less severe neutropenia and febrile neutropenia. Therefore, a weekly docetaxel regimen has become increasingly common in cancer treatment. Premedication with corticosteroids can effectively prevent or reduce the severity of hypersensitivity and fluid retention. However, no recommended steroid dosage for a weekly docetaxel regimen has been established to date. The aim of this study is to compare the efficacy and complications of two different weekly docetaxel premedication protocols. METHODS: We retrospectively compared the hypersensitivity, hyperglycemia, and infection incidence associated with two weekly docetaxel premedication protocols. The control group (dexamethasone 10 mg intravenously and 4 mg orally every 12 h for four doses, starting 1 h before docetaxel administration) patients started weekly docetaxel chemotherapy between May 2012 and April 2013 at Seoul National University Hospital, and the experimental group (dexamethasone 10 mg intravenously 1 h prior to each docetaxel administration) patients started weekly docetaxel chemotherapy between May 2013 and April 2014. RESULTS: In total, 109 patients in the control group and 97 patients in the experimental group were included in this study, and there were no statistically significant differences in baseline characteristics between the two groups. The incidence of hypersensitivity and hyperglycemia were similar, but infections were observed significantly less in the experimental group (p = 0.020, OR = 0.408, 0.0190-0.0879). CONCLUSIONS: A low-dose dexamethasone premedication protocol has comparable efficacy in the prevention of docetaxel hypersensitivity with fewer infection complications. Therefore, we recommend a low-dose dexamethasone premedication protocol for weekly docetaxel regimens. PMID- 27687723 TI - Residential road traffic noise exposure and survival after breast cancer - A cohort study. AB - BACKGROUND: It is generally acknowledged that patients with already existing clinical conditions are especially vulnerable to the effects of traffic noise exposure. The aim of the present study was to investigate the association between residential road traffic noise and breast cancer survival. METHODS: Road traffic noise was calculated for all residential addresses from 1987 to February 2012 for incident breast cancer cases (n=1,759) in a cohort of 57,053 Danes. We used Cox Proportional Hazard Models to investigate the association between residential road traffic noise at different time-windows, and overall and breast cancer specific mortality. Furthermore, we investigated interaction with prognostic and socioeconomic factors. Mortality Rate Ratios (MRR) were calculated in both unadjusted models, and adjusted for residential railway noise, lifestyle factors and socioeconomic variables. RESULTS: During a median of 7.3 years of follow-up, 402 patients died; 274 from breast cancer. We found no association between time weighted averages of residential road traffic noise 1-, 3- or 5-years before death, or over the entire follow-up period, and overall or breast cancer-specific mortality. A 10dB higher road traffic noise from diagnosis until censoring was associated with an adjusted MRR of 0.94 (0.81-1.08) for all-cause mortality. The association was modified by lymph node involvement, with a MRR of 1.20 (0.97 1.48) for those with tumor-positive lymph nodes and 0.76 (0.59-0.98) for those without. CONCLUSION: The present study suggests no association between residential road traffic noise and concurrent mortality. As it is the first study of its kind, with relatively limited power, further studies are warranted. PMID- 27687724 TI - Crystal Structure of the Acid Sphingomyelinase-like Phosphodiesterase SMPDL3B Provides Insights into Determinants of Substrate Specificity. AB - The enzyme acid sphingomyelinase-like phosphodiesterase 3B (SMPDL3B) was shown to act as a negative regulator of innate immune signaling, affecting cellular lipid composition and membrane fluidity. Furthermore, several reports identified this enzyme as an off target of the therapeutic antibody rituximab, with implications in kidney disorders. However, structural information for this protein is lacking. Here we present the high resolution crystal structure of murine SMPDL3B, which reveals a substrate binding site strikingly different from its paralogs. The active site is located in a narrow boot-shaped cavity. We identify a unique loop near the active site that appears to impose size constraints on incoming substrates. A structure in complex with phosphocholine indicates that the protein recognizes this head group via an aromatic box, a typical choline-binding motif. Although a potential substrate for SMPDL3B is sphingomyelin, we identify other possible substrates such as CDP-choline, ATP, and ADP. Functional experiments employing structure-guided mutagenesis in macrophages highlight amino acid residues potentially involved in recognition of endogenous substrates. Our study is an important step toward elucidating the specific function of this poorly characterized enzyme. PMID- 27687725 TI - Protein Phosphatase PP5 Controls Bone Mass and the Negative Effects of Rosiglitazone on Bone through Reciprocal Regulation of PPARgamma (Peroxisome Proliferator-activated Receptor gamma) and RUNX2 (Runt-related Transcription Factor 2). AB - Peroxisome proliferator-activated receptor gamma (PPARgamma) and runt-related transcription factor 2 (RUNX2) are key regulators of mesenchymal stem cell (MSC) differentiation toward adipocytes and osteoblasts, respectively. Post translational modifications of these factors determine their activities. Dephosphorylation of PPARgamma at Ser-112 is required for its adipocytic activity, whereas phosphorylation of RUNX2 at serine 319 (Ser-319) promotes its osteoblastic activity. Here we show that protein phosphatase 5 (PP5) reciprocally regulates each receptor by targeting each serine. Mice deficient in PP5 phosphatase have increased osteoblast numbers and high bone formation, which results in high bone mass in the appendicular and axial skeleton. This is associated with a substantial decrease in lipid-containing marrow adipocytes. Indeed, in the absence of PP5 the MSC lineage allocation is skewed toward osteoblasts and away from lipid accumulating adipocytes, although an increase in beige adipocyte gene expression is observed. In the presence of rosiglitazone, PP5 translocates to the nucleus, binds to PPARgamma and RUNX2, and dephosphorylates both factors, resulting in activation of PPARgamma adipocytic and suppression of RUNX2 osteoblastic activities. Moreover, shRNA knockdown of PP5 results in cells refractory to rosiglitazone treatment. Lastly, mice deficient in PP5 are resistant to the negative effects of rosiglitazone on bone, which in wild type animals causes a 50% decrease in trabecular bone mass. In conclusion, PP5 is a unique phosphatase reciprocally regulating PPARgamma and RUNX2 activities in marrow MSC. PMID- 27687726 TI - Psoralen and Ultraviolet A Light Treatment Directly Affects Phosphatidylinositol 3-Kinase Signal Transduction by Altering Plasma Membrane Packing. AB - Psoralen and ultraviolet A light (PUVA) are used to kill pathogens in blood products and as a treatment of aberrant cell proliferation in dermatitis, cutaneous T-cell lymphoma, and graft-versus-host disease. DNA damage is well described, but the direct effects of PUVA on cell signal transduction are poorly understood. Because platelets are anucleate and contain archetypal signal transduction machinery, they are ideally suited to address this. Lipidomics on platelet membrane extracts showed that psoralen forms adducts with unsaturated carbon bonds of fatty acyls in all major phospholipid classes after PUVA. Such adducts increased lipid packing as measured by a blue shift of an environment sensitive fluorescent probe in model liposomes. Furthermore, the interaction of these liposomes with lipid order-sensitive proteins like amphipathic lipid packing sensor and alpha-synuclein was inhibited by PUVA. In platelets, PUVA caused poor membrane binding of Akt and Bruton's tyrosine kinase effectors following activation of the collagen glycoprotein VI and thrombin protease activated receptor (PAR) 1. This resulted in defective Akt phosphorylation despite unaltered phosphatidylinositol 3,4,5-trisphosphate levels. Downstream integrin activation was furthermore affected similarly by PUVA following PAR1 (effective half-maximal concentration (EC50), 8.4 +/- 1.1 versus 4.3 +/- 1.1 MUm) and glycoprotein VI (EC50, 1.61 +/- 0.85 versus 0.26 +/- 0.21 MUg/ml) but not PAR4 (EC50, 50 +/- 1 versus 58 +/- 1 MUm) signal transduction. Our findings were confirmed in T-cells from graft-versus-host disease patients treated with extracorporeal photopheresis, a form of systemic PUVA. In conclusion, PUVA increases the order of lipid phases by covalent modification of phospholipids, thereby inhibiting membrane recruitment of effector kinases. PMID- 27687727 TI - Prohibitin 1 Regulates the H19-Igf2 Axis and Proliferation in Hepatocytes. AB - Prohibitin 1 (PHB1) is a mitochondrial chaperone that regulates cell growth. Phb1 knock-out mice exhibit liver injury and hepatocellular carcinoma (HCC). Phb1 knock-out livers show induction of tumor growth-associated genes, H19 and insulin like growth factor 2 (Igf2). These genes are controlled by the imprinting control region (ICR) containing CCCTC-binding transcription factor (CTCF)-binding sites. Because Phb1 knock-out mice exhibited induction of H19 and Igf2, we hypothesized that PHB1-mediated regulation of the H19-Igf2 axis might control cell proliferation in normal hepatocytes. H19 and Igf2 were induced (8-20-fold) in 3 week-old Phb1 knock-out livers, in Phb1 siRNA-treated AML12 hepatocytes (2-fold), and HCC cell lines when compared with control. Phb1 knockdown lowered CTCF protein in AML12 by ~30% when compared with control. CTCF overexpression lowered basal H19 and Igf2 expression by 30% and suppressed Phb1 knockdown-mediated induction of these genes. CTCF and PHB1 co-immunoprecipitated and co-localized on the ICR element, and Phb1 knockdown lowered CTCF ICR binding activity. The results suggest that PHB1 and CTCF cooperation may control the H19-Igf2 axis. Human HCC tissues with high levels of H19 and IGF2 exhibited a 40-50% reduction in PHB1 and CTCF expression and their ICR binding activity. Silencing Phb1 or overexpressing H19 in the mouse HCC cell line, SAMe-D, induced cell growth. Blocking H19 induction prevented Phb1 knockdown-mediated growth, whereas H19 overexpression had the reverse effect. Interestingly H19 silencing induced PHB1 expression. Taken together, our results demonstrate that the H19-Igf2 axis is negatively regulated by CTCF-PHB1 cooperation and that H19 is involved in modulating the growth-suppressive effect of PHB1 in the liver. PMID- 27687728 TI - Alternative Selection of beta-Site APP-Cleaving Enzyme 1 (BACE1) Cleavage Sites in Amyloid beta-Protein Precursor (APP) Harboring Protective and Pathogenic Mutations within the Abeta Sequence. AB - beta-Site APP-cleaving enzyme 1 (BACE1) cleaves amyloid beta-protein precursor (APP) at the bond between Met671 and Asp672 (beta-site) to generate the carboxyl terminal fragment (CTFbeta/C99). BACE1 also cleaves APP at another bond between Thr681 and Gln682 (beta'-site), yielding CTFbeta'/C89. Cleavage of CTFbeta/C99 by gamma-secretase generates Abeta(1-XX), whereas cleavage of CTFbeta'/C89 generates Abeta(11-XX). Thus, beta'-site cleavage by BACE1 is amyloidolytic rather than amyloidogenic. beta' cleavage of mouse APP is more common than the corresponding cleavage of human APP. We found that the H684R substitution within human Abeta, which replaces the histidine in the human protein with the arginine found at the corresponding position in mouse, facilitated beta' cleavage irrespective of the species origin of BACE1, thereby significantly increasing the level of Abeta(11 XX) and decreasing the level of Abeta(1-XX). Thus, amino acid substitutions within the Abeta sequence influenced the selectivity of alternative beta- or beta'-site cleavage of APP by BACE1. In familial Alzheimer's disease (FAD), the APP gene harbors pathogenic variations such as the Swedish (K670N/M671L), Leuven (E682K), and A673V mutations, all of which decrease Abeta(11-40) generation, whereas the protective Icelandic mutation (A673T) increases generation of Abeta(11-40). Thus, A673T promotes beta' cleavage of APP and protects subjects against AD. In addition, CTFbeta/C99 was cleaved by excess BACE1 activity to generate CTFbeta'/C89, followed by Abeta(11-40), even if APP harbored pathogenic mutations. The resultant Abeta(11-40) was more metabolically labile in vivo than Abeta(1-40). Our analysis suggests that some FAD mutations in APP are amyloidogenic and/or amyloidolytic via selection of alternative BACE1 cleavage sites. PMID- 27687729 TI - Forkhead Box O3A (FOXO3) and the Mitochondrial Disulfide Relay Carrier (CHCHD4) Regulate p53 Protein Nuclear Activity in Response to Exercise. AB - Although exercise is linked with improved health, the specific molecular mechanisms underlying its various benefits require further clarification. Here we report that exercise increases the nuclear localization and activity of p53 by acutely down-regulating coiled-coil-helix-coiled-coil-helix domain 4 (CHCHD4), a carrier protein that mediates p53 import into the mitochondria. This response to exercise is lost in transgenic mice with constitutive expression of CHCHD4. Mechanistically, exercise-induced nuclear transcription factor FOXO3 binds to the CHCHD4 promoter and represses its expression, preventing the translocation of p53 to the mitochondria and thereby increasing p53 nuclear localization. The synergistic increase in nuclear p53 and FOXO3 by exercise can facilitate their known interaction in transactivating Sirtuin 1 (SIRT1), a NAD+-dependent histone deacetylase that mediates adaptation to various stresses. Thus, our results reveal one mechanism by which exercise could be involved in preventing cancer and potentially other diseases associated with aging. PMID- 27687731 TI - Conjugative DNA-transfer in Streptomyces, a mycelial organism. AB - Conjugative DNA-transfer in the Gram-positive mycelial soil bacterium Streptomyces, well known for the production of numerous antibiotics, is a unique process involving the transfer of a double-stranded DNA molecule. Apparently it does not depend on a type IV secretion system but resembles the segregation of chromosomes during bacterial cell division. A single plasmid-encoded protein, TraB, directs the transfer from the plasmid-carrying donor to the recipient. TraB is a FtsK-like DNA-translocase, which recognizes a specific plasmid sequence, clt, via interaction with specific 8-bp repeats. Chromosomal markers are mobilized by the recognition of clt-like sequences randomly distributed all over the Streptomyces chromosomes. Fluorescence microcopy with conjugative reporter plasmids and differentially labelled recipient strains revealed conjugative plasmid transfer at the lateral walls of the hyphae, when getting in contact. Subsequently, the newly transferred plasmids cross septal cross walls, which occur at irregular distances in the mycelium and invade the neighboring compartments, thus efficiently colonizing the recipient mycelium. This intramycelial plasmid spreading requires the DNA-translocase TraB and a complex of several Spd proteins. Inactivation of a single spd gene interferes with intramycelial plasmid spreading. The molecular function of the Spd proteins is widely unknown. Spd proteins of different plasmids are highly diverse, none showing sequence similarity to a functionally characterized protein. The integral membrane protein SpdB2 binds DNA, peptidoglycan and forms membrane pores in vivo and in vitro. Intramycelial plasmid spreading is an adaptation to the mycelial growth characteristics of Streptomyces and ensures the rapid dissemination of the plasmid within the recipient colony before the onset of sporulation. PMID- 27687730 TI - Neuropilin 2 Signaling Is Involved in Cell Positioning of Adult-born Neurons through Glycogen Synthase Kinase-3beta (GSK3beta). AB - Proper positioning of neurons is fundamental for brain functions. However, little is known on how adult-born neurons generated in the hilar side of hippocampal dentate gyrus migrate into the granular cell layer. Because class 3 Semaphorins (Sema3) are involved in dendritic growth of these newborn neurons, we examined whether they are essential for cell positioning. We disrupted Sema3 signaling by silencing neuropilin 1 (NRP1) or 2 (NRP2), the main receptors for Sema3A and Sema3F, in neural progenitors of adult mouse dentate gyrus. Silencing of NRP2, but not NRP1, affected cell positioning of adult newborn neurons. Glycogen synthase kinase-3beta (GSK3beta) knockdown phenocopied this NRP2 silencing mediated cell positioning defect, but did not affect dendritic growth. Furthermore, GSK3beta is activated upon stimulation with Sema3F, and GSK3beta overexpression rescued the cell positioning phenotypes seen in NRP2-deficient neurons. These results point to a new role for NRP2 in the positioning of neurons during adult hippocampal neurogenesis, acting via the GSK3beta signaling pathway. PMID- 27687732 TI - Late-Onset Friedreich's Ataxia (LOFA) Mimicking Charcot-Marie-Tooth Disease Type 2: What Is Similar and What Is Different? AB - Herein, we report a patient that presented with late-onset progressive steppage gait, neuropathy and pes cavus, suggesting Charcot-Marie-Tooth (CMT) disease. Subsequent genetic investigation confirmed Friedreich's ataxia (FRDA). We demonstrate that late-onset Friedreich's ataxia (LOFA) may be a CMT mimicker. This case reinforces that other genetic conditions may clinically resemble CMT. The clinical similarities between CMT and FRDA include a symmetrical neuropathy (axonal in FRDA), steppage gait, and eventually scoliosis. We suggest that late onset forms of hereditary neuropathies should be carefully evaluated, since LOFA may be a CMT mimicker. PMID- 27687733 TI - Dominant factor analysis of B-flow twinkling sign with phantom and simulation data. AB - BACKGROUND AND PURPOSE: The twinkling sign in B-flow imaging (BFI-TS) has been reported in the literature to increase both specificity and sensitivity compared to the traditional gray-scale imaging. Unfortunately, there has been no conclusive study on the mechanism of this effect. METHODS: In the study presented here, a comparative test on phantoms is introduced, where the variance of a phase estimator is used to quantify the motion amplitude. The statistical inference is employed later to find the dominate factor for the twinkling sign, which is proven by computer simulation. RESULTS: Through the analysis, it is confirmed that the tissue viscoelasticity is closely coupled with the twinkling sign. Moreover, the acoustic radiation force caused by tissue attenuation is found to be the trigger of the twinkling sign. CONCLUSION: Based on these findings, the BFI-TS is interpreted as a tissue movement triggering vibration of microcalcifications particle. PMID- 27687734 TI - Sonoreperfusion Therapy Kinetics in Whole Blood Using Ultrasound, Microbubbles and Tissue Plasminogen Activator. AB - Coronary intervention for myocardial infarction often results in microvascular embolization of thrombus. Sonoreperfusion therapy (SRP) using ultrasound and microbubbles restored perfusion in our in vitro flow model of microvascular obstruction. In this study, we assessed SRP efficacy using whole blood as the perfusate with and without tissue plasminogen activator (tPA). In a phantom vessel bearing a 40-MUm-pore mesh to simulate the microvasculature, microthrombi were injected to cause microvascular obstruction and were treated using SRP. Without tPA, the lytic rate increased from 2.6 +/- 1.5 mmHg/min with 1000-cycle pulses to 7.3 +/- 3.2 mmHg/min with 5000-cycle ultrasound pulses (p < 0.01). The lytic index was similar for tPA-only ([2.0 +/- 0.5] * 10-3 mmHg-1 min-1) and 5000 cycles without tPA ([2.3 +/- 0.5] * 10-3 mmHg-1 min-1) (p = 0.5) but increased ([3.6 +/- 0.8] * 10-3 mmHg-1 min-1) with tPA in conjunction with 5000-cycles ultrasound (p < 0.01). In conclusion, SRP restored microvascular perfusion in whole blood, SRP lytic rate in experiments without tPA increased with ultrasound pulse length and efficacy increased with the addition of tPA. PMID- 27687736 TI - The Case Report of Priapus and a Modern Approach to an Ancient Affliction. AB - INTRODUCTION: Priapism, taking its name from God Priapus, is total or partial erection lasting longer than 4 hours independent of sexual stimulus and can result in erectile dysfunction. There are three subtypes of priapism. AIM: To review the three subtypes of priapism, their pathophysiology, current treatment options, and complications. METHODS: The literature including priapism guidelines, review articles, and current trial studies was reviewed and the priapism type of God Priapus was investigated according to the mythology. MAIN OUTCOME MEASURES: All three types of priapism were reviewed for etiology, diagnosis, and management. Medical and surgical treatment options were reviewed in relation to the current literature. Special emphasis concerned current treatment strategies and controversial surgical topics. RESULTS: Ischemic priapism is the most common type, constituting 95% of all cases, and is an emergency. First-line treatments are blood aspiration and intracavernosal sympathomimetic drug injections. If these fail, then surgical shunt operations are recommended. A T-shunt combined with corporal tunneling is the currently popular option. Immediate penile prosthesis implantation is recommended for patients who present 48 to 72 hours after the onset of a priapism episode. High flow priapism is caused by irregular arterial cavernosal blood flow, which usually occurs after a blunt perineal trauma. Antiandrogens and selective arterial embolization are the treatment options. Stuttering priapism is repetitive, self-limiting ischemic priapism and frequent in patients with sickle cell anemia. Ketoconazole is safe, cheap, and effective and appears to be a logical and suitable current treatment option to prevent further episodes, which is the primary treatment goal of stuttering priapism. CONCLUSION: Priapism is a relatively common condition but not well known by clinicians. The lack and delay of treatment result in irreversible complications such as erectile dysfunction. Each type of priapism should be diagnosed and treated correctly with caution. PMID- 27687735 TI - CellMapper: rapid and accurate inference of gene expression in difficult-to isolate cell types. AB - We present a sensitive approach to predict genes expressed selectively in specific cell types, by searching publicly available expression data for genes with a similar expression profile to known cell-specific markers. Our method, CellMapper, strongly outperforms previous computational algorithms to predict cell type-specific expression, especially for rare and difficult-to-isolate cell types. Furthermore, CellMapper makes accurate predictions for human brain cell types that have never been isolated, and can be rapidly applied to diverse cell types from many tissues. We demonstrate a clinically relevant application to prioritize candidate genes in disease susceptibility loci identified by GWAS. PMID- 27687737 TI - Nutritional risk factors and status of serum 25(OH)D levels in patients with breast cancer: A case control study in India. AB - To study the nutritional risk factors and status of serum 25(OH)D levels in patients with breast cancer. A total of 100 women (cases) with confirmed breast cancer (BC) matched with equal number of healthy females (controls) of similar age and socioeconomic status (SES) were included in study. Controls included were nonbreast cancer patients who accompanied the patients to a tertiary care hospital. All the subjects (cases and controls) were administered a questionnaires to collect data on socioeconomic status, dietary pattern and the frequency of food consumption using a validated food frequency questionnaire. Anthropometric assessment was done for waist and hip circumference to calculate waist to hip ratio (WHR). Non fasting blood samples were collected for serum 25 hydroxyvitamin D [25(OH)D] levels estimation using chemiluminescent immunoassay technique and total serum calcium levels by colorimetric assay technique. Serum 25(OH)D and total calcium levels were expressed in ng/ml and mg/dl. Vitamin D deficiency was defined as per the guidelines set by United States Endocrine Society. The mean age of cases and controls was 45+/-9 and 46+/-10 years respectively. On multivariate analysis, an inverse association with BC was found for less frequency of fruits consumption with an adjusted (ORs, 95% CI) (2.7, 0.5 15.7) respectively. Mushroom intake was inversely associated with risk of BC (ORs, 95% CI) (5.6, 1.9-16.6). Saturated fat intake and high WHR were significantly associated with high risk of BC with adjusted ORs, 95% CI of (3.4, 1.4-8.1) and (5, 1.4-17). A significant association (p<0.05) was found between low serum 25(OH)D levels and the risk of BC with adjusted ORs, 95% CI of (2.5, 0.9-7.4). Majority of the patients with BC were suffering from vitamin D deficiency. Dietary intake of mushrooms containing vitamin D naturally was found to be associated with decreased risk of breast cancer. A significant association was found between low serum 25(OH)D levels (<20ng/ml) with the risk of BC. Obesity as a consequence of nutritional risk factors determined by higher WHR was found to be significantly associated with the risk of BC. PMID- 27687738 TI - Serum 25-hydroxyvitamin D concentration is not associated with glomerular filtration rate in a predominantly obese otherwise healthy population. AB - Evidence from observational studies indicates a role for vitamin D in kidney function and progression to chronic kidney disease. Findings from animal studies have proposed underlying mechanisms including increased activation of the renin angiotensin system, increased blood pressure, insulin resistance and chronic low grade inflammation. However, human studies are limited by confounders arising from heterogeneous samples of participants. We examined the relationship between 25(OH)D and estimated glomerular filtration rate (eGFR) in a predominantly obese otherwise healthy and drug-naive population with no history of chronic kidney disease (CKD). One hundred and twenty one non-diabetic (75g oral glucose tolerance test; OGTT) volunteers (70 males and 51 females), aged 18-57 years participated in the study. Median 25(OH)D level was 37nmol/L with no difference by sex. Twenty six participants (21.5%) had 25(OH)D <25 nmol/L, 75 participants (62%) had 25(OH)D of 25-49.99nmol/L, and 20 participants (16.5%) had 25(OH)D >=50nmol/L. In univariate analysis, 25(OH)D was related negatively to percent body fat and 2-h glucose level post OGTT. Mean (SD) eGFR was 113.1 (14.9)mL/min/1.73m2, and in the multivariable analysis, it was related to age, sex, percent body fat and 2-h glucose level post OGTT, but not to 25(OH)D. Furthermore, there was no relationship between eGFR and 25(OH)D across BMI categories. Our data suggest that measuring 25(OH)D in predominantly obese otherwise healthy individuals with no history of CKD may not be beneficial in early recognition of kidney disease. PMID- 27687739 TI - Electroencephalographic coupling in the amygdala and prefrontal cortex in relation to the estrous cycle and duration of vaginocervical stimulation in the rat. AB - The influence of the duration of vaginocervical stimulation (VCS) on the electroencephalographic activity (EEG) of medial amygdala (MeA) and prefrontal cortex (PFC) in rats during proestrus-estrus (P-E) and diestrus (D) was examined. Using a glass syringe plunger, a constant force of 300g was exerted against the cervix during 60s. Relative power (RP) and correlation of three EEG band frequencies were compared between the first and last 30s intervals of VCS. A higher RP of the 4-7Hz band and a lower RP of the fast frequencies were observed in the MeA and PFC in P-E females during the first 30s of VCS as compared to the last 30s. Only during P-E, a higher interamygdaline correlation in the 8-12Hz band and a lower correlation in the 13-21Hz band during the first 30s were observed. Similarly, a higher interamygdaline correlation in the 8-12Hz band was observed during the first 30s of VCS during P-E as compared to D. During the last 30s of VCS there was no difference between phases. The VCS evoked EEG changes in the MeA that varied between phases of the estrous cycle and depended on the duration of the stimulation. These effects could be associated with the quantification processes of VCS that has been proposed to occur in the amygdala. These findings show differential responsiveness of the MeA and PFC according to the amount of VCS received, and that the response varies according to the estrous cycle. PMID- 27687740 TI - Opposite effects of acute and chronic amphetamine on Nurr1 and NF-kappaB p65 in the rat ventral tegmental area. AB - Dopamine neurons are overstimulated by drugs of abuse and suffer molecular alterations that lead to addiction behavior. Nurr1 is a transcription factor crucial for dopamine neurons survival and dopamine production, activating the transcription of key genes like tyrosine hydroxylase (TH). Interestingly, nuclear factor-kappa B (NF-kappaB) has emerged as a new Nurr1 partner in response to inflammatory stimulus. In this study we evaluated the effects of single and repeated amphetamine administration in the expression of Nurr1 and the NF-kappaB p65 subunit in the rat ventral tegmental area (VTA). We found that acute amphetamine treatment increased Nurr1, p65 and TH protein levels in the VTA. On the other hand, chronic amphetamine treatment decreased Nurr1 and p65 protein levels, but TH was unchanged. Mammalian reporter assays in cell lines showed that p65 represses Nurr1 transcriptional activity in an artificial promoter driven by Nurr1 response elements and in the native rat TH promoter. These results indicate that Nurr1 and NF-kappaB p65 factors are involved in the adaptive response of dopamine neurons to psychostimulants and that both transcription factors could be regulating Nurr1-dependent transactivation in the VTA. PMID- 27687741 TI - Treatment outcomes of endoscopic resection for rectal carcinoid tumors: an analysis of the resectability and long-term results from 46 consecutive cases. AB - AIM: In Japan, most of colorectal carcinoid tumors developed in rectum. The choice of treatment is important because surgical treatment may need to construct artificial anus. Although curative endoscopic resection (ER) is desirable from the point of quality of life, sufficient evidence of endoscopic treatment for rectal carcinoid tumors is not fully obtained. METHODS: Between April 2001 and August 2013, 46 rectal carcinoid tumors in 46 patients who underwent either with endoscopic mucosal resection with a ligation device (EMR-L) or endoscopic submucosal dissection (ESD) were analyzed retrospectively. The rates of en bloc resection, positive for lateral and/or vertical margin, curative resection, local recurrence, additional treatments, overall and disease-specific survival rate after ER were evaluated during follow-up (median observation period 61.6 months). RESULTS: Twenty-two lesions were treated by EMR-L and 24 lesions were treated by ESD. Both groups had similar mean tumor size (EMR-L: 6.2 mm, ESD: 6.0 mm). The rate of en bloc resection, negative for both lateral and vertical margins, and curative resection were, respectively, 73%, 63%, and 50% for EMR-L, 100%, 100%, and 83% for ESD. These results suggested that the rate of resectability and curability for ESD was significantly higher than EMR-L (p < 0.05). Complications such as perforation and bleeding did not occur in both groups. Fifteen patients were judged as non-curative and 3 patients underwent additional surgery and lymph node metastasis was evident in 1 patient. Remained 11 patients were carefully followed-up, and so far no obvious recurrence was found. Thirty-two patients (84%) were eligible for long-term follow-up and 5-year overall and disease specific survival rates were 100% and 100%, respectively. CONCLUSION: The long term outcomes of ER for rectal carcinoid tumors were excellent. ESD has advantage for resectability and curability compared with EMR-L; therefore, ESD is more favorable procedure as treatment for rectal carcinoid tumors. PMID- 27687742 TI - The effects of intermittent calorie restriction on metabolic health: Rationale and study design of the HELENA Trial. AB - Mechanistic studies suggest benefits of intermittent calorie restriction (ICR) in chronic disease prevention that may exceed those of continuous calorie restriction (CCR), even at equal net calorie intake. Despite promising results from first trials, it remains largely unknown whether ICR-induced metabolic alterations reported from experimental studies can also be observed in humans, and whether ICR diets are practicable and effective in real life situations. Thus, we initiated the HELENA Trial to test the effects of ICR (eu-caloric diet on five days and very low energy intake on two days per week) on metabolic parameters and body composition over one year. We will assess the effectiveness of ICR compared to CCR and a control diet over a 12-week intervention, 12-week maintenance phase and 24-week follow-up in 150 overweight or obese non-smoking adults (50 per group, 50% women). Our primary endpoint is the difference between ICR and CCR with respect to fold-changes in expression levels of 82 candidate genes in abdominal subcutaneous adipose tissue biopsies (SATb) during the intervention phase. The candidate genes represent pathways, which may link obesity-related metabolic alterations with the risk for major chronic diseases. In secondary and exploratory analyses, changes in metabolic, hormonal, inflammatory and metagenomic parameters measured in different biospecimens (SATb, blood, urine, stool) are investigated and effects of ICR/CCR/control on imaging based measures of subcutaneous, visceral and hepatic fat are evaluated. Our study is the first randomized trial over one year testing the effects of ICR on metabolism, body composition and psychosocial factors in humans.

AB - The ability to set realistic expectations of treatment response in patients with overactive bladder (OAB) can have an impact on patient engagement and adherence to study medication. In order to help set treatment expectations for OAB, a Physician Predictive Tool has been developed based on predictive modelling. Models have been developed utilizing data from eight Phase 3 and 4 fesoterodine clinical trials and these models enable the prediction of individual treatment response in subjects with OAB, based on various baseline characteristics. The data utilized and covariates that were hypothesized to influence treatment response are described. The model selection and development process are also outlined, and the final model and some example results utilizing this model are presented. Finally, we discuss the potential benefits and limitations of such a predictive tool. PMID- 27687745 TI - Exploring the Relationship Between Online Social Network Site Usage and the Impact on Quality of Life for Older and Younger Users: An Interaction Analysis. AB - BACKGROUND: Analyzing content generated by users of social network sites has been shown to be beneficial across a number of disciplines. Such analysis has revealed the precise behavior of users that details their distinct patterns of engagement. An issue is evident whereby without direct engagement with end users, the reasoning for anomalies can only be the subject of conjecture. Furthermore, the impact of engaging in social network sites on quality of life is an area which has received little attention. Of particular interest is the impact of online social networking on older users, which is a demographic that is specifically vulnerable to social isolation. A review of the literature reveals a lack of knowledge concerning the impact of these technologies on such users and even less is known regarding how this impact varies across different demographics. OBJECTIVE: The objective of our study was to analyze user interactions and to survey the attitudes of social network users directly, capturing data in four key areas: (1) functional usage, (2) behavioral patterns, (3) technology, and (4) quality of life. METHODS: An online survey was constructed, comprising 32 questions. Each question directly related to a research question. Respondents were recruited through a variety of methods including email campaigns, Facebook advertisements, and promotion from related organizations. RESULTS: In total, data was collected from 919 users containing 446 younger and 473 older users. In comparison to younger users, a greater proportion of older users (289/473, 61.1% older vs 218/446, 48.9% younger) (P<.001) stated that Facebook had either a positive or huge impact on their quality of life. Furthermore, a greater percentage of older users strongly agreed that Facebook strengthened their relationship with other people (64/473, 13.5% older vs 40/446, 9.0%younger) (P=.02). In comparison to younger users, a greater proportion of older users had more positive emotions-classified as slightly better or very good-during their engagement with Facebook (186/473, 39.3% older vs 120/446, 26.9% younger) (P<.001). CONCLUSIONS: The results reveal that despite engaging at considerably lower rates with significantly fewer connections, older users gain a greater quality-of-life benefit. Results disclose how both cohorts vary in their use, interactions, and rationale for engaging with Facebook. PMID- 27687743 TI - Ethical and clinical safety considerations in the design of an effectiveness trial: A comparison of buprenorphine versus naltrexone treatment for opioid dependence. AB - We examine ethical challenges encountered in the design of an effectiveness trial (CTN-0051; X:BOT), comparing sublingual buprenorphine-naloxone (BUP-NX), an established treatment for opioid dependence, to the newer extended-release injectable naltrexone (XR-NTX). Ethical issues surrounded: 1) known poor effectiveness of one possible, commonly used treatment as usual control condition detoxification followed by counseling without medication; 2) the role of patients' preferences for treatments, given that treatments were clinically approved and available to the population; 3) differences between the optimal "usual treatment" clinical settings for different treatments making it challenging to design a fair comparison; 4) vested interest groups favoring different treatments exerting potential influence on the design process; 5) potentially vulnerable populations of substance users and prisoners; 6) potential therapeutic misconception in the implementation of safety procedures; and 7) high cost of a large trial limiting questions that could be addressed. We examine how the design features underlying these ethical issues are characteristic of effectiveness trials, which are often large trials that compare treatments with varying degrees of existing effectiveness data and familiarity to patients and clinicians, in community-based treatment settings, with minimal exclusion criteria that could involve vulnerable populations. Hence, investigators designing effectiveness trials may wish to remain alert to the possibility of similar ethical issues. PMID- 27687746 TI - Unresectability during open surgical exploration in planned cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. AB - BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy are the treatment of choice for selected patients with peritoneal metastasis. Despite a stringent selection process, some patients were found to be unresectable only at surgery, which leads to disappointment and poor utilisation of limited infrastructural resources. This study aims to determine the pre operative factors associated with unresectability in planned CRS and HIPEC. METHODS: Retrospective analysis of 172 consecutive patients eligible for CRS and HIPEC at the National Cancer Centre Singapore from April 2004 to May 2014 was performed. Pre-operative factors (clinical presentation, disease factors, and investigation findings) between the unresectable (13%) and the successful groups (87%) were compared. RESULTS: Patient demographics between the two cohorts were comparable. In terms of clinical presentation, the unresectable group was more likely to present with bloating (p = .00), altered bowel habits (p = .04), abdominal distension (p = .00), palpable abdominal masses (p = .00) and palpable pouch of Douglas nodules (p = .00). Differences were also noted in disease factors with the unresectable group having more high-grade tumours (p = .01), inadequate initial resections (p = .01), progression through chemotherapy (p = .00) and shorter median disease-free intervals (p = .03). In addition, investigations in the unresectable group revealed more patients with elevated tumour markers (p = .01), thrombocytosis (p = .00) and computed tomography findings of ascites (p = .00), omental thickening (p = .00), lymphadenopathy (p = .02) and small bowel disease (p = .00). CONCLUSIONS: Significant factors associated with unresectability that were identified in our study could potentially create a new treatment algorithm and refine current selection process to exclude patients at risk of unresectability in planned CRS and HIPEC.

PMID- 27687748 TI - Use of Twitter Polls to Determine Public Opinion Regarding Content Presented at a Major National Specialty Society Meeting. AB - PURPOSE: The aim of this study was to evaluate the feasibility of using Twitter polls to assess public opinion regarding session content at a national specialty society meeting. METHODS: Twitter polls allow users to embed multiple-choice questions within tweets and automatically aggregate responses. Two radiologists attending the 2016 annual meeting of the ACR posted a Twitter poll containing the hashtag #ACR2016 during 10 meeting sessions addressing socioeconomics/advocacy, patient experience, and social media/informatics (20 polls total). Each poll contained a question asking for an opinion regarding the session's content. Polls were open for responses for 24 hours. RESULTS: The average number of responses per poll was significantly higher for the user with the larger number of Twitter followers (24.3 +/- 14.4 versus 11.2 +/- 9.8, P = .015). A total of 57% of respondents agreed that radiologists' payments should shift to value-based payments, and 86% agreed that radiologists should routinely survey their patients to monitor quality; however, 83% disagreed with basing physician payments on patient satisfaction scores. A total of 85% disagreed that the artificial intelligence supercomputer Watson will entirely replace radiologists. A total of 76% agreed that social media can drive business at less cost than standard marketing. A total of 56% agreed with the direction of the ACR's advocacy and regulatory efforts, whereas 74% considered the ACR's advocacy efforts to be moderately or very useful for their practice. A total of 50% planned to change their practice on the basis of keynote remarks by Dr Ezekiel Emanuel. CONCLUSIONS: Twitter polls provide a free and easy infrastructure to potentially capture global public sentiment during the course of a medical society meeting. Their use may enrich and promote discussions of key session content. PMID- 27687749 TI - The Economic and Social Value of an Image Exchange Network: A Case for the Cloud. AB - As the health care environment continually changes, radiologists look to the ACR's Imaging 3.0(r) initiative to guide the search for value. By leveraging new technology, a cloud-based image exchange network could provide secure universal access to prior images, which were previously siloed, to facilitate accurate interpretation, improved outcomes, and reduced costs. The breast imaging department represents a viable starting point given the robust data supporting the benefit of access to prior imaging studies, existing infrastructure for image sharing, and the current workflow reliance on prior images. This concept is scalable not only to the remainder of the radiology department but also to the broader medical record.

PMID- 27687751 TI - Partnering With Your Health System to Select and Implement Clinical Decision Support for Imaging. AB - Recent legislation mandates the documentation of appropriateness criteria consultation when ordering advanced imaging for Medicare patients to remain eligible for reimbursement. Implementation of imaging clinical decision support (CDS) is a solution adopted by many systems to automate compliance with the new requirements. This article is intended to help radiologists who are employed by, contracted with, or otherwise affiliated with systems planning to implement CDS in the near future and ensure that they are able to understand and contribute to the process wherever possible. It includes an in-depth discussion of the legislation, evidence for and against the efficacy of imaging CDS, considerations for selecting a CDS vendor, tips for configuring CDS in a fashion consistent with departmental goals, and pointers for implementation and change management. PMID- 27687752 TI - What Do Women Know About Breast Density? Results From a Population Survey of Virginia Women. AB - PURPOSE: Breast density reduces the sensitivity of mammography and is a moderate independent risk factor for breast cancer. Virginia is one of 24 states that currently require notification of patients when they have dense breasts. However, little is known about what women in the general population know about breast density. This survey study assessed knowledge about breast density and about its impact on mammography and breast cancer risk. METHODS: A random sample of 1024 Virginia women between ages 35 and 70 years without breast cancer, reached by landline and cell phone, who completed a 24-minute interview. Bivariate and multivariate analysis was performed. RESULTS: Thirty-six percent of respondents had been informed about their breast density. These women were more likely to be familiar with the term "breast density." Seventy-five percent of respondents reported being either somewhat or very familiar with risk factors for breast cancer, but <1% spontaneously listed breast density as a risk factor. About half of women who had a mammogram in the last year were aware of their breast density. Overall, only one in five women were aware that density reduces the sensitivity of mammography and only one in eight were aware that density increases breast cancer risk. Very few respondents (5.3%) were able to correctly answer three density knowledge questions. Lower-education, African-American, and Jewish women were less knowledgeable about breast density. CONCLUSIONS: Although women are becoming aware of the term "breast density," they may not understand its relationship to cancer detection on mammography and, especially, its relationship to breast cancer risk. PMID- 27687753 TI - Telehealth monitor to measure physical activity and pressure relief maneuver performance in wheelchair users. AB - This study demonstrated the feasibility of a device for monitoring pressure relief maneuvers and physical activity for wheelchair users. The device counts the number of wheel pushes based on wheelchair acceleration and measures pressure relief maneuvers using a seat sensor consisting of three force sensing resistors (FSRs). To establish the feasibility of the seat sensor for the detection of pressure relief maneuvers, 10 wheelchair users and 10 non-disabled controls completed a series of wheelchair depression raises, forward trunk leans, and lateral trunk leans. The seat sensor was placed underneath the user's seat cushion. To establish the feasibility of wheel push counting, 10 full-time wheelchair users navigated a flat 50-m outdoor track and a 100-m outdoor obstacle course during self-propulsion (e.g., wheel pushes) and during assisted-propulsion (e.g., no wheel pushes). Of the 240 performed pressure relief, 225 were properly classified by the seat sensor (accuracy: 94%, sensitivity: 96%, specificity: 80%). Sensitivity was highest for depression raises (98%) and lowest for front lean maneuvers (80%). The wheelchair activity monitor measured 2,112 pushes during the self-propulsion trials compared to 2,162 pushes measured with the instrumented push-rim (97.7%). During assisted-propulsion trials, there were 477 incorrectly identified pushes (8.0 per trial).

AB - Annona squamosa L. fruit played great anti-neoplastic activities. Its pericarps were discarded as waste. In this study, essential oil extracted from A. squamosa L. pericarps (APEO) was obtained by hydrodistillation and analysed by GC-MS. Furthermore, the anti-hepatoma activities and the underlying mechanism of the oil were firstly described. A total of 59 compounds were identified by Gas chromatography-mass spectrometry (GC-MS). The major compound in the oil was (-) spathulenol (32.51%). The APEO demonstrated anti-hepatoma activity against SMMC 7721 hepatoma cell line with IC50 lower than 55 MUg/mL. At the same time, nucleus shrinkage or broken were found in cells incubated with APEO through fluorescent microscope. In addition, pro-apoptosis and cell cycle arrest effects were confirmed by flow cytometry analysis. PMID- 27687756 TI - Erratum to: Perfluoroalkyl acids in aqueous samples from Germany and Kenya. PMID- 27687757 TI - Comparative effects of direct-fed microbials alone or with a trace minerals supplements on the productive performance, blood metabolites, and antioxidant status in grazing Awassi lambs. AB - Twenty Awassi lambs were used to find the effects of direct-fed microbials (DFM) and long-acting trace minerals rumen bolus (TMB) supplements on performance, blood biochemical variables, and antioxidant status of the lambs under grazing conditions. The lambs were randomly distributed into four groups as follows: (1) untreated, (2) oral dose of 5 mL DFM, (3) TMB, or (4) oral dose of 5 mL DFM and TMB. The treatments were carried out for 90 days. Supplementation with TMB significantly increased (P < 0.05) average daily gain (ADG) and feed efficiency compared with the control. A significant (P < 0.05) increase in blood albumin in the DFM and a significant (P < 0.05) decrease in aspartate aminotrasferase were found in the lambs supplemented with TMB alone or in combination with DFM. Supplementing lambs with TMB resulted in higher glutathione peroxidase, total antioxidant capacity (P < 0.001) and activity of superoxide dismutase (P < 0.05) compared with no supplementation and supplementation with DFM only. In conclusion, TMB supplementation had a positive impact on performance traits and the antioxidant system of the lambs under grazing condition. PMID- 27687755 TI - Aspergillosis and stem cell transplantation: An overview of experimental pathogenesis studies. AB - Invasive aspergillosis is a life-threatening infection caused by the opportunistic filamentous fungus Aspergillus fumigatus. Patients undergoing haematopoietic stem cell transplant (HSCT) for the treatment of hematological malignancy are at particularly high risk of developing this fatal infection. The susceptibility of HSCT patients to infection with A. fumigatus is a consequence of a complex interplay of both fungal and host factors. Here we review our understanding of the host-pathogen interactions underlying the susceptibility of the immunocompromised host to infection with A. fumigatus with a focus on the experimental validation of fungal and host factors relevant to HSCT patients. These include fungal factors such as secondary metabolites, cell wall constituents, and metabolic adaptations that facilitate immune evasion and survival within the host microenvironment, as well as the innate and adaptive immune responses involved in host defense against A. fumigatus. PMID- 27687758 TI - Erythrocyte micronucleus cytome assay of 17 wild bird species from the central Monte desert, Argentina. AB - Birds have the potential to be considered valuable bioindicators of the quality of ecosystems and the environmental impact of pollutants. The aims of this study were to determine the micronuclei frequency and other nuclear abnormalities in erythrocytes by analyzing a wild bird community from central Monte desert (Argentina) and to clarify if there were any differences among certain species. Frequencies of nuclear abnormalities were determined in 73 wild birds belonging to 17 species and two orders (Passeriformes and Columbiformes). A high proportion of individuals, 90.4 and 80.9 %, had erythrocytes with micronuclei and nuclear buds, respectively. Notched nuclei, binucleated cells, nuclear tails, and nucleoplasmic bridges were also recorded. Certain species appeared to be more informative than others with regard to the possibility of being used as bioindicators of genetic damage. Saltator aurantiirostris and Columbina picui were the only species that showed significantly different frequencies of nuclear alterations, in comparison with the other species. The frequencies here presented are the first reported for these bird species from the orders Passeriformes and Columbiformes. This research supports the notion that the use of these biomarkers could be effectively applied to evaluate spontaneous or induced genetic instability in wild birds. PMID- 27687759 TI - Sorption of selected pharmaceuticals and pesticides on different river sediments. AB - In the present work, the sorption ability of 17 pharmaceutical compounds, two metabolites, and 15 pesticides (34 target compounds in total) onto four different river sediments was investigated separately. Selected compounds present the most frequently prescribed pharmaceuticals in human and animal medicine and the most frequently used pesticides in agriculture. Their presence into the surface, ground, and waste waters was confirmed into the numerous papers in literature, as well as their presence into the river sediments (for some of them). However, investigations of their sorption onto the river sediments, as major natural protection from potential pollution of ground water by them is missing. Sorption in this study was investigated onto river sediments taken from rivers in the Republic of Serbia, where only less than 10 % of total generated waste water passes through mainly basic treatment processes. Experiments were based on batch equilibrium procedures and obtained solutions were analyzed by previously developed and validated sensitive high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) analytical methods. All results were modeled by Freundlich isotherms. Obtained results have shown that Kf coefficient values are in correlation with organic carbon content. Kd sorption coefficient values were relatively low and ranged in wide ranges for almost all compounds and sediments. That implicates on the conclusion that capacities of the investigated sorbents are not large for those compounds. PMID- 27687760 TI - Organophosphate pesticide in agricultural soils from the Yangtze River Delta of China: concentration, distribution, and risk assessment. AB - Organophosphorus pesticides (OPPs) are used worldwide and pose great risks to human health. However, information on their presence in agricultural soils at regional scale and the associated risks is limited. In this study, an extensive investigation on agricultural soils was conducted throughout the Yangtze River Delta (YRD) of China to reveal the status of OPP pollution. The total concentrations of the nine OPPs ranged from <3.0 to 521 ng g-1 dry weight, with a mean of 64.7 ng g-1 dry weight and a detection rate of 93 %. Dimethoate was found to be the primary compound, followed by methyl parathion and parathion. The highest concentrations of OPPs were found in Jiangsu province due to the intensive agricultural activities. The pollution of OPPs is also highly associated with the land use types. The lower concentrations of OPPs found in vegetable fields could be attributed to their easy photodegradation and hydrolysis in aerobic soils. There was no significant difference in microbial communities among the sample sites, indicating that OPPs in agricultural soils of the YRD region cause negligible effects on microbiota. The risks of OPPs in the soils to human health were further evaluated. The hazard indexes in all the soil samples were below 1, suggesting absence of non-cancer risks. This study provides valuable information for a better understanding of the pollution status of OPPs in agricultural soils and a scientific basis for soil quality assessments. PMID- 27687761 TI - Development of a fuzzy-stochastic programming with Green Z-score criterion method for planning water resources systems with a trading mechanism. AB - This study developed a fuzzy-stochastic programming with Green Z-score criterion (FSGZ) method for water resources allocation and water quality management with a trading-mechanism (WAQT) under uncertainties. FSGZ can handle uncertainties expressed as probability distributions, and it can also quantify objective/subjective fuzziness in the decision-making process. Risk-averse attitudes and robustness coefficient are joined to express the relationship between the expected target and outcome under various risk preferences of decision makers and systemic robustness. The developed method is applied to a real-world case of WAQT in the Kaidu-Kongque River Basin in northwest China, where an effective mechanism (e.g., market trading) to simultaneously confront severely diminished water availability and degraded water quality is required. Results of water transaction amounts, water allocation patterns, pollution mitigation schemes, and system benefits under various scenarios are analyzed, which indicate that a trading-mechanism is a more sustainable method to manage water-environment crisis in the study region. Additionally, consideration of anthropogenic (e.g., a risk-averse attitude) and systemic factors (e.g., the robustness coefficient) can support the generation of a robust plan associated with risk control for WAQT when uncertainty is present. These findings assist local policy and decision makers to gain insights into water-environment capacity planning to balance the basin's social and economic growth with protecting the region's ecosystems. PMID- 27687762 TI - Temporal stability analysis of surface soil water content on two karst hillslopes in southwest China. AB - Knowledge of the temporal variability of soil water content (SWC) at the hillslope scale is essential for guiding rehabilitation strategies and for optimizing water resource management in the karst region of southwest China. This study aimed to use temporal stability analysis to upscale point-scale measurements to represent mean areal SWC on two typical karst hillslopes. Based on a grid sampling scheme (10 m * 10 m) applied to two 90 m * 120 m plots located on two hillslops, the SWC at a depth of 0-16 cm was measured 11-12 times across 259 sampling points, using time domain reflectometry (TDR) from April 2011 to October 2012. Soil texture, bulk density (BD), saturated hydraulic conductivity (K s ), organic carbon (SOC), rock fragment content (RFC), and site elevation (SE) were also measured at these locations. Results showed the hillslope with more shrub cover was wetter than the hillslope with mixed grass-shrub cover. This difference was related to the differences in soil texture, soil hydraulic permeability, and topography. Through a comparison of values obtained with the Spearman correlation coefficient (r s ), standard deviation of mean relative difference (SDRD), and mean absolute bias error (MABE), we inferred that there is a higher degree of temporal stability for SWC in wet conditions than in drier conditions on the two hillslopes. Based on the values of the index of temporal stability (ITS), which combine the mean relative difference (MRD) and SDRD, the two locations were determined to be representative of mean SWC on both hillslopes. Moreover, these locations captured changes in mean SWC (NSCE = 0.69, and 0.65, and RMSE = 1.96, and 1.96 %, respectively). This demonstrates the feasibility of using the temporal stability of SWC to acquire mean SWC on karst hillslopes of southwestern China. The indirect method, which estimates mean SWC by considering the offset between the mean and the measurement value at a time stable location, predicted mean SWC (NSCE = 0.86, and 0.76, and RMSE = 1.29, and 1.63 %, respectively) more precisely than the direct method (mean SWC directly measured at a time-stable location), because it eliminates deviation by introducing a constant offset (MRD). We recommended the use of the indirect method to acquire mean SWC values, when an allowable bias of 5 % for both MRD and SDRD can not be achieved. In addition, we found that soil texture, RFC, and elevation affect the pattern of SWC on the shrub hillslope. These results are expected to be useful for monitoring soil water dynamics on karst hillslopes, especially for restoration purposes.

AB - Aluminum is ingested through foods, water, air, and even drugs. Its intake is potentiated further through foods and tea prepared in aluminum utensils and Al salt added in the drinking water for removal of suspended impurities and also fluoride in the affected areas. The ameliorating role of a blue green alga Spirulina is well documented to various pollutants in the animal models. We, therefore, examined its protective role (230 mg/kg body weight) on the hematology of male Swiss albino mice treated with aluminum (sub-acute = 78.4 mg/kg body weight for 7 days, sub-chronic = 7.8 mg/kg body weight for 90 days) and aluminum fluoride (sub-acute = 103 mg/kg body weight, sub-chronic = 21 mg/kg body weight), along with their recovery after 90 days of sub-chronic exposure. This study revealed significant reduction in the values of RBC (5-18 %), Hb (15-17 %), PCV (8-14 %), and platelets (26-36 %), and increase in WBC (54-124 %) in the treated mice, particularly after sub-acute exposure. Aluminum fluoride was comparatively more toxic than aluminum. Further, Spirulina supplement not only alleviated toxicity of test chemicals in Swiss albino mice but also led to their better recovery after withdrawal. PMID- 27687765 TI - Unleashing the potential of ligninolytic bacterial contributions towards pulp and paper industry: key challenges and new insights. AB - Lignocellulose biomass predominantly constitutes the main feedstock for pulp and paper industry. Though some products of pulp and paper industry require the presence of lignin content, for most of the useful products formation lies in the efficient and selective removal of lignin component to make use of the intact cellulose fraction during the pretreatment of pulp. Lignin is a recalcitrant heteropolymer comprised of several complex stable bonds and linkages. The chemicals or intense energy processes used for delignification process release the hazardous chemicals compounds in the wastewater which cause toxicity and environmental pollution. The implementation of bacterial species has elucidated an effective approach in the generation of value-added products while degrading lignin from pulp biomass as well as detoxification of effluent. The direct use of bacterial cells in lignocellulose biomass and wastewater streams is promising as it outperforms the practical and technical constraints largely confronted by fungal and enzymatic means. The present review paper thus unleashed the potential of ligninolytic bacteria towards delignification of pulp biomass and treatment of effluent together with bioconversion of biomass and lignin into value-added products.

PMID- 27687766 TI - Auditory cortical field coding long-lasting tonal offsets in mice. AB - Although temporal information processing is important in auditory perception, the mechanisms for coding tonal offsets are unknown. We investigated cortical responses elicited at the offset of tonal stimuli using flavoprotein fluorescence imaging in mice. Off-responses were clearly observed at the offset of tonal stimuli lasting for 7 s, but not after stimuli lasting for 1 s. Off-responses to the short stimuli appeared in a similar cortical region, when conditioning tonal stimuli lasting for 5-20 s preceded the stimuli. MK-801, an inhibitor of NMDA receptors, suppressed the two types of off-responses, suggesting that disinhibition produced by NMDA receptor-dependent synaptic depression might be involved in the off-responses. The peak off-responses were localized in a small region adjacent to the primary auditory cortex, and no frequency-dependent shift of the response peaks was found. Frequency matching of preceding tonal stimuli with short test stimuli was not required for inducing off-responses to short stimuli. Two-photon calcium imaging demonstrated significantly larger neuronal off-responses to stimuli lasting for 7 s in this field, compared with off responses to stimuli lasting for 1 s. The present results indicate the presence of an auditory cortical field responding to long-lasting tonal offsets, possibly for temporal information processing. PMID- 27687767 TI - Perspectives in neonatal and childhood arterial ischemic stroke. AB - INTRODUCTION: Over the last decade considerable advances have been made in the identification, understanding and management of pediatric arterial ischemic stroke. Such increasing knowledge has also brought new perspectives and interrogations in the current acute and rehabilitative care of these patients. Areas covered: In developed countries, focal cerebral arteriopathy is one of the most common causes of arterial ischemic stroke in childhood and imaging features are well characterized. However, there are ongoing debates regarding its underlying mechanisms, natural evolution and proper management. The implementation of thrombolytic therapy in acute pediatric stroke has been shown to be efficient in anecdotal cases but is still limited by a number of caveats, even in large tertiary centers. Finally, neonatal stroke represents a unique circumstance of possible early intervention before the onset of any neurological disability but this appears meaningful only in a selective group of neonates. Expert commentary: While perinatal stroke, a leading cause of cerebral palsy, appears to be multifactorial, a large number of childhood ischemic stroke are probably essentially triggered by infectious factors leading to vessel wall damage. Current research is aiming at better identifying risk factors in both conditions, and to define optimal acute and preventive therapeutic strategies in order to reduce significant long-term morbidity. PMID- 27687768 TI - Angiotensin-(1-7) abrogates angiotensin II-induced proliferation, migration and inflammation in VSMCs through inactivation of ROS-mediated PI3K/Akt and MAPK/ERK signaling pathways. AB - The proliferation, migration and inflammation of vascular smooth muscle cells (VSMCs) contribute to the pathogenesis and progression of several cardiovascular diseases such as atherosclerosis and hypertension. Angiotensin (Ang)-(1-7) and Ang II are identified to be involved in regulating cardiovascular activity. The present study is designed to determine the interaction between Ang-(1-7) and Ang II on VSMCs proliferation, migration and inflammation as well as their underlying mechanisms. We found that Ang-(1-7) significantly suppressed the positive effects of Ang II on VSMCs proliferation, migration and inflammation, as well as on induction of the phosphorylation of Akt and ERK1/2 and increase of superoxide anion level and NAD(P)H oxidase activity in VSMCs, whereas Ang-(1-7) alone had no significant effects. This inhibitory effects of Ang-(1-7) were abolished by Mas receptor antagonist A-779. In addition, Ang II type 1 (AT1) receptor antagonist losartan, but not A-779, abolished Ang II induced VSMCs proliferation, migration and inflammation responses. Furthermore, superoxide anion scavenger N-acetyl-L cysteine (NAC) or NAD(P)H oxidase inhibitor apocynin inhibited Ang II-induced activation of Akt and ERK1/2 signaling. These results indicate that Ang-(1-7) antagonizes the Ang II-induced VSMC proliferation, migration and inflammation through activation of Mas receptor and then suppression of ROS-dependent PI3K/Akt and MAPK/ERK signaling pathways. PMID- 27687770 TI - Collective modes in multi-Weyl semimetals. AB - We investigate collective modes in three dimensional (3D) gapless multi-Weyl semimetals with anisotropic energy band dispersions (i.e., with a positive integer J). For comparison, we also consider the gapless semimetals with the isotropic band dispersions (i.e. E ~ kJ). We calculate analytically long wavelength plasma frequencies incorporating interband transitions and chiral properties of carriers. For both the isotropic and anisotropic cases, we find that interband transitions and chirality lead to the depolarization shift of plasma frequencies. For the isotropic parabolic band dispersion the long wavelength plasmons do not decay via Landau damping, while for the higher-order band dispersions the long-wavelength plasmons experience damping below a critical density. For systems with the anisotropic dispersion the density dependence of the long-wavelength plasma frequency along the direction of non-linear dispersion behaves like that of the isotropic linear band model, while along the direction of linear dispersion it behaves like that of the isotropic non-linear model. Plasmons along both directions remain undamped over a broad range of densities due to the chirality induced depolarization shift. Our results provide a comprehensive picture of how band dispersion and chirality affect plasmon behaviors in 3D gapless chiral systems with the arbitrary band dispersion. PMID- 27687769 TI - Ultrasound and MRI predictors of surgical bowel resection in pediatric Crohn disease. AB - BACKGROUND: Imaging predictors for surgery in children with Crohn disease are lacking. OBJECTIVE: To identify imaging features of the terminal ileum on short interval bowel ultrasound (US) and MR enterography (MRE) in children with Crohn disease requiring surgical bowel resection and those managed by medical therapy alone. MATERIALS AND METHODS: This retrospective study evaluated patients 18 years and younger with Crohn disease undergoing short-interval bowel US and MRE (within 2 months of one another), as well as subsequent ileocecectomy or endoscopy within 3 months of imaging. Appearance of the terminal ileum on both modalities was compared between surgical patients and those managed with medical therapy, with the following parameters assessed: bowel wall thickness, mural stratification, vascularity, fibrofatty proliferation, abscess, fistula and stricture on bowel US; bowel wall thickness, T2 ratio, enhancement pattern, mesenteric edema, fibrofatty proliferation, abscess, fistula and stricture on MRE. A two-sided t-test was used to compare means, a Mann-Whitney U analysis was used for non-parametric parameter scores, and a chi-square or two-sided Fisher exact test compared categorical variables. Imaging findings in surgical patients were correlated with location-matched histopathological scores of inflammation and fibrosis using a scoring system adapted from the Simple Endoscopic Score for Crohn Disease, and a Spearman rank correlation coefficient was used to compare inflammation and fibrosis on histopathology. RESULTS: Twenty-two surgical patients (mean age: 16.5 years; male/female: 13/9) and 20 nonsurgical patients (mean age: 14.8; M/F: 8/12) were included in the final analysis. On US, the surgical group demonstrated significantly increased mean bowel wall thickness (6.1 mm vs. 4.7 mm for the nonsurgical group; P = 0.01), loss of mural stratification (odds ratio [OR] = 6.3; 95% confidence interval [CI]: 1.4-28.4; P = 0.02) and increased fibrofatty proliferation (P = 0.04). On MRE, the surgical group showed increased mean bowel wall thickness (9.1 mm vs. 7.2 mm for the nonsurgical group; P = 0.02), increased mean T2 ratio (4.6 vs. 3.6 for the nonsurgical group; P = 0.03), different enhancement patterns (P = 0.03), increased mesenteric edema (P = 0.001) and increased stricture formation (OR = 8.2; 95% CI: 1.8-36.4; P = 0.005). Nineteen of 22 ileocecectomy specimens showed severe inflammation and 21/22 showed severe fibrosis, with significant correlation between inflammation and fibrosis scores (rho = 0.55; P = 0.008); however, correlation with imaging findings was limited by the uniformity of findings on histopathology. CONCLUSION: Children with terminal ileal Crohn disease requiring surgical bowel resection demonstrate more severe manifestations of imaging features traditionally associated with both active inflammation and chronic fibrosis than those managed medically on US and MRE, findings that are corroborated by histopathology. These features may potentially serve as imaging biomarkers indicating the necessity for surgical intervention. PMID- 27687772 TI - A ketone/alcohol polymer for cycle of electrolytic hydrogen-fixing with water and releasing under mild conditions. AB - Finding a safe and efficient carrier of hydrogen is a major challenge. Recently, hydrogenated organic compounds have been studied as hydrogen storage materials because of their ability to stably and reversibly store hydrogen by forming chemical bonds; however, these compounds often suffer from safety issues and are usually hydrogenated with hydrogen at high pressure and/or temperature. Here we present a ketone (fluorenone) polymer that can be moulded as a plastic sheet and fixes hydrogen via a simple electrolytic hydrogenation at -1.5 V (versus Ag/AgCl) in water at room temperature. The hydrogenated alcohol derivative (the fluorenol polymer) reversibly releases hydrogen by heating (80 degrees C) in the presence of an aqueous iridium catalyst. Both the use of a ketone polymer and the efficient hydrogen fixing with water as a proton source are completely different from other (de)hydrogenated compounds and hydrogenation processes. The easy handling and mouldable polymers could suggest a pocketable hydrogen carrier. PMID- 27687771 TI - CSL protein regulates transcription of genes required to prevent catastrophic mitosis in fission yeast. AB - For every eukaryotic cell to grow and divide, intricately coordinated action of numerous proteins is required to ensure proper cell-cycle progression. The fission yeast Schizosaccharomyces pombe has been instrumental in elucidating the fundamental principles of cell-cycle control. Mutations in S. pombe 'cut' (cell untimely torn) genes cause failed coordination between cell and nuclear division, resulting in catastrophic mitosis. Deletion of cbf11, a fission yeast CSL transcription factor gene, triggers a 'cut' phenotype, but the precise role of Cbf11 in promoting mitotic fidelity is not known. We report that Cbf11 directly activates the transcription of the acetyl-coenzyme A carboxylase gene cut6, and the biotin uptake/biosynthesis genes vht1 and bio2, with the former 2 implicated in mitotic fidelity. Cbf11 binds to a canonical, metazoan-like CSL response element (GTGGGAA) in the cut6 promoter. Expression of Cbf11 target genes shows apparent oscillations during the cell cycle using temperature-sensitive cdc25-22 and cdc10-M17 block-release experiments, but not with other synchronization methods. The penetrance of catastrophic mitosis in cbf11 and cut6 mutants is nutrient-dependent. We also show that drastic decrease in biotin availability arrests cell proliferation but does not cause mitotic defects. Taken together, our results raise the possibility that CSL proteins play conserved roles in regulating cell-cycle progression, and they could guide experiments into mitotic CSL functions in mammals. PMID- 27687773 TI - Plant virus infections control stomatal development. AB - Stomata are important regulators of carbon dioxide uptake and transpirational water loss. They also represent points of vulnerability as bacterial and fungal pathogens utilise this natural opening as an entry portal, and thus have an increasingly complex relationship. Unlike the situation with bacterial and fungal pathogens, we know very little about the role of stomata in viral infection. Here we report findings showing that viral infection influences stomatal development in two susceptible host systems (Nicotiana tabacum with TMV (Tobacco mosaic virus), and Arabidopsis thaliana with TVCV (Turnip vein-clearing virus)), but not in resistant host systems (Nicotiana glutinosa and Chenopodium quinoa with TMV). Virus infected plants had significantly lower stomatal indices in systemic leaves of susceptible systems; N. tabacum 9.8% reduction and A. thaliana 12.3% reduction, but not in the resistant hosts. Stomatal density in systemic leaves was also significantly reduced in virus infected A. thaliana by 19.6% but not in N. tabacum or the resistant systems. In addition, transpiration rate was significantly reduced in TMV infected N. tabacum. PMID- 27687774 TI - Clinical characteristics of women with reproductive cycle-associated bipolar disorder symptoms. AB - OBJECTIVE: Although there is clear evidence that reproductive cycle events are associated with mood episodes for women with bipolar disorder, few studies have examined for relationships between these and specific clinical characteristics of the disorder. This study aimed to explore the relationship between mood symptoms associated with reproductive cycle events and features of the disorder indicative of a more severe lifetime course. METHOD: Totally, 158 women of at least 18 years of age participated in the study. Subjects were recruited through a specialist clinic at the Black Dog Institute, Sydney, Australia. RESULTS: In total, 77% of women reported increases in mood symptoms during perimenstrual, postnatal or menopausal periods. These women had an earlier age of onset for depressive and hypo/manic episodes and a greater likelihood of comorbid anxiety disorders, rapid cycling and mixed mood compared to those who did not report such reproductive cycle-associated mood changes. Women who experienced postnatal episodes were also more likely to experience worse mood symptoms perimenstrually and menopausally. CONCLUSION: First, reproductive cycle event-related worsening of mood was associated with a more severe lifetime course of bipolar disorder, and, second, it appears that some women have a greater propensity to mood worsening at each of these reproductive cycle events. If replicated, these findings provide important information for clinicians treating women with reproductive cycle event mood changes and highlight the need for improved therapeutics for such presentations.

AB - The distribution of ions into a bilayer lipid membrane (BLM) and their adsorption on the BLM are investigated by extracting a hydrophobic cation, rhodamine 6G (R6G+), into a liposome through the dialysis membrane method. R6G+ distribution mainly depends upon the concentration of the coexisting anion and its species (Cl , Br-, BF4-, ClO4-, and picrate). On the other hand, R6G+ adsorption on the BLM surface follows the Langmuir adsorption model and is independent of the coexisting anion in the aqueous phase. We propose an extraction model of ionic species into the BLM, to explain the dependence of extraction of ionic species upon the coexisting anion. In this model, an ion is distributed with a coexisting counterion into the BLM and then forms an ion pair in the BLM. Here, the ion adsorption equilibrium on the BLM surface is independent of the species and concentration of the coexisting counterion under the same ionic strength. On the basis of this model, we estimate the distribution constant of R6G+ and anion (KD), the ion-pair formation constant in the BLM (Kip), and the R6G+ adsorption constant on the BLM surface (Kad). Even for an ultrathin membrane system, such as a BLM, R6G+ is distributed with a coexisting counterion and the distribution equilibrium of the ionic species at the water-BLM interface is analyzable similar to that at the water-organic solvent interface. PMID- 27687780 TI - Single-cell RNA sequencing reveals dynamic changes in A-to-I RNA editome during early human embryogenesis. AB - BACKGROUND: A-to-I RNA-editing mediated by ADAR (adenosine deaminase acting on RNA) enzymes that converts adenosine to inosine in RNA sequence can generate mutations and alter gene regulation in metazoans. Previous studies have shown that A-to-I RNA-editing plays vital roles in mouse embryogenesis. However, the RNA-editing activities in early human embryonic development have not been investigated. RESULTS: Here, we characterized genome-wide A-to-I RNA-editing activities during human early embryogenesis by profiling 68 single cells from 29 human embryos spanning from oocyte to morula stages. We demonstrate dynamic changes in genome-wide RNA-editing during early human embryogenesis in a stage specific fashion. In parallel with ADAR expression level changes, the genome-wide A-to-I RNA-editing levels in cells remained relatively stable until 4-cell stage, but dramatically decreased at 8-cell stage, continually decreased at morula stage. We detected 37 non-synonymously RNA-edited genes, of which 5 were frequently found in cells of multiple embryonic stages. Moreover, we found that A to-I editings in miRNA-targeted regions of a substantial number of genes preferably occurred in one or two sequential stages. CONCLUSIONS: Our single-cell analysis reveals dynamic changes in genome-wide RNA-editing during early human embryogenesis in a stage-specific fashion, and provides important insights into early human embryogenesis. PMID- 27687782 TI - Giant superconducting fluctuations in the compensated semimetal FeSe at the BCS BEC crossover. AB - The physics of the crossover between weak-coupling Bardeen-Cooper-Schrieffer (BCS) and strong-coupling Bose-Einstein condensate (BEC) limits gives a unified framework of quantum-bound (superfluid) states of interacting fermions. This crossover has been studied in the ultracold atomic systems, but is extremely difficult to be realized for electrons in solids. Recently, the superconducting semimetal FeSe with a transition temperature Tc=8.5 K has been found to be deep inside the BCS-BEC crossover regime. Here we report experimental signatures of preformed Cooper pairing in FeSe, whose energy scale is comparable to the Fermi energies. In stark contrast to usual superconductors, large non-linear diamagnetism by far exceeding the standard Gaussian superconducting fluctuations is observed below T*~20 K, providing thermodynamic evidence for prevailing phase fluctuations of superconductivity. Nuclear magnetic resonance and transport data give evidence of pseudogap formation at ~T*. The multiband superconductivity along with electron-hole compensation in FeSe may highlight a novel aspect of the BCS-BEC crossover physics. PMID- 27687783 TI - Increased GABAB receptor signaling in a rat model for schizophrenia. AB - Schizophrenia is a complex disorder that affects cognitive function and has been linked, both in patients and animal models, to dysfunction of the GABAergic system. However, the pathophysiological consequences of this dysfunction are not well understood. Here, we examined the GABAergic system in an animal model displaying schizophrenia-relevant features, the apomorphine-susceptible (APO-SUS) rat and its phenotypic counterpart, the apomorphine-unsusceptible (APO-UNSUS) rat at postnatal day 20-22. We found changes in the expression of the GABA synthesizing enzyme GAD67 specifically in the prelimbic- but not the infralimbic region of the medial prefrontal cortex (mPFC), indicative of reduced inhibitory function in this region in APO-SUS rats. While we did not observe changes in basal synaptic transmission onto LII/III pyramidal cells in the mPFC of APO-SUS compared to APO-UNSUS rats, we report reduced paired-pulse ratios at longer inter stimulus intervals. The GABAB receptor antagonist CGP 55845 abolished this reduction, indicating that the decreased paired-pulse ratio was caused by increased GABAB signaling. Consistently, we find an increased expression of the GABAB1 receptor subunit in APO-SUS rats. Our data provide physiological evidence for increased presynaptic GABAB signaling in the mPFC of APO-SUS rats, further supporting an important role for the GABAergic system in the pathophysiology of schizophrenia. PMID- 27687786 TI - Assessment of average of normals (AON) procedure for outlier-free datasets including qualitative values below limit of detection (LoD): an application within tumor markers such as CA 15-3, CA 125, and CA 19-9. AB - Average of normals (AON) is a quality control procedure that is sensitive only to systematic errors that can occur in an analytical process in which patient test results are used. The aim of this study was to develop an alternative model in order to apply the AON quality control procedure to datasets that include qualitative values below limit of detection (LoD). The reported patient test results for tumor markers, such as CA 15-3, CA 125, and CA 19-9, analyzed by two instruments, were retrieved from the information system over a period of 5 months, using the calibrator and control materials with the same lot numbers. The median as a measure of central tendency and the median absolute deviation (MAD) as a measure of dispersion were used for the complementary model of AON quality control procedure. The ubias values, which were determined for the bias component of the measurement uncertainty, were partially linked to the percentages of the daily median values of the test results that fall within the control limits. The results for these tumor markers, in which lower limits of reference intervals are not medically important for clinical diagnosis and management, showed that the AON quality control procedure, using the MAD around the median, can be applied for datasets including qualitative values below LoD. PMID- 27687785 TI - An original pharmacoepidemiological-pharmacodynamic method: application to antipsychotic-induced movement disorders. AB - AIMS: Pharmacovigilance databases are usually used to detect new potential signals that are relevant for drug safety. They are seldom used for explanatory purposes, e.g. to understand the mechanisms of adverse drug reactions (ADRs). The aim of the present study was to combine pharmacovigilance and pharmacodynamic data to investigate the association between dopamine D2, serotonin 5HT2A, and muscarinic M1 receptor occupancy and the risks of antipsychotic drug (AP)-induced movement disorders. METHODS: First, we performed a case-noncase analysis using spontaneous reports from the World Health Organization (WHO) Global Individual Case Safety Report (ICSR) database, VigiBase(r). We thus measured the risk of reporting movement disorders compared with all other ADRs [expressed as a reporting odds ratio (ROR)] for APs. Second, we performed a linear regression analysis to explore the association between the estimated risk of reporting for individual drugs and their receptor occupancy properties, for D2, 5HT2A and M1 receptors. RESULTS: Compared with second-generation APs, first-generation APs were found to be significantly more associated with the reporting of movement disorders in general but also with dystonia, Parkinsonism, akathisia and tardive dyskinesia, irrespective of gender. A significant inverse correlation was found between the ROR for movement disorders and the receptor occupancy of 5HT2A [P < 0.001; R2 = 0.51; slope = -0.014; 95% confidence interval (CI) (-0.029, 0.001)], M1 (P < 0.001; R2 = 0.56; slope = -0.014; 95% CI (-0.028, 0.001) but not D2 dopamine (P = 0.54; R2 = 0.02; slope = -0.003; 95% CI (-0.007, 0.001) receptors. CONCLUSIONS: Using the example of AP-induced movement disorders, the present study underlines the value of the pharmacoepidemiological-pharmacodynamic method to explore ADR mechanisms in humans and real-life settings. PMID- 27687787 TI - Illness perception in patients with coronary artery disease: A systematic review. AB - The aim of this study was to conduct a systematic review that investigates the differences in illness perception with age and gender in patients diagnosed with coronary artery disease. Previous studies show some discrepancies regarding the influence of age and gender on the specific dimensions of coronary artery disease patients' illness perception. A systematic review using a narrative synthesis process included preliminary synthesis, exploration of relationships and assessment of the robustness of the synthesis and findings was conducted. Search terms were used to identify research studies published between 1996 and December 2014 across four key databases: CINAHL, Medline, PsycINFO and Web of Science. A total of 14 studies met the inclusion criteria of the review. The review found that men had a stronger perception that their own behaviour had caused their illness than women. In addition, older patients had lower perceptions of the consequences and chronicity of their illness. This analysis concludes that some dimensions of illness perception vary according to age and gender of patients with coronary artery disease. These differences should be taken into consideration, particularly when providing health education and cardiac rehabilitation. PMID- 27687784 TI - Addressing the inter-individual variation in response to consumption of plant food bioactives: Towards a better understanding of their role in healthy aging and cardiometabolic risk reduction. AB - Bioactive compounds in plant-based foods have health properties that contribute to the prevention of age-related chronic diseases, particularly cardiometabolic disorders. Conclusive proof and understanding of these benefits in humans is essential in order to provide effective dietary recommendations but, so far, the evidence obtained from human intervention trials is limited and contradictory. This is partly due to differences between individuals in the absorption, distribution, metabolism and excretion of bioactive compounds, as well as to heterogeneity in their biological response regarding cardiometabolic health outcomes. Identifying the main factors underlying inter-individual differences, as well as developing new and innovative methodologies to account for such variability constitute an overarching goal to ultimately optimize the beneficial health effects of plant food bioactives for each and every one of us. In this respect, this position paper from the COST Action FA1403-POSITIVe examines the main factors likely to affect the individual responses to consumption of plant food bioactives and presents perspectives for assessment and consideration of inter-individual variability.

AB - Subway systems worldwide transport more than 100 million people daily; therefore, air quality on station platforms and inside trains is an important urban air pollution issue. We examined the microbiological composition and abundance in space and time of bioaerosols collected in the Barcelona subway system during a cold period. Quantitative PCR was used to quantify total bacteria, Aspergillus fumigatus, influenza A and B, and rhinoviruses. Multitag 454 pyrosequencing of the 16S rRNA gene was used to assess bacterial community composition and biodiversity. The results showed low bioaerosol concentrations regarding the targeted microorganisms, although the bacterial bioburden was rather high (104 bacteria/m3 ). Airborne bacterial communities presented a high degree of overlap among the different subway environments sampled (inside trains, platforms, and lobbies) and were dominated by a few widespread taxa, with Methylobacterium being the most abundant genus. Human-related microbiota in sequence dataset and ascribed to potentially pathogenic bacteria were found in low proportion (maximum values below 2% of sequence readings) and evenly detected. Hence, no important biological exposure marker was detected in any of the sampled environments. Overall, we found that commuters are not the main source of bioaerosols in the Barcelona subway system. PMID- 27687791 TI - Needle Trap Device as a New Sampling and Preconcentration Approach for Volatile Organic Compounds of Herbal Medicines and its Application to the Analysis of Volatile Components in Viola tianschanica. AB - INTRODUCTION: The needle trap device (NTD) technique is a new microextraction method for sampling and preconcentration of volatile organic compounds (VOCs). Previous NTD studies predominantly focused on analysis of environmental volatile compounds in the gaseous and liquid phases. Little work has been done on its potential application in biological samples and no work has been reported on analysis of bioactive compounds in essential oils from herbal medicines. OBJECTIVE: The main purpose of the present study is to develop a NTD sampling method for profiling VOCs in biological samples using herbal medicines as a case study. METHODOLOGY: A combined method of NTD sample preparation and gas chromatography-mass spectrometry was developed for qualitative analysis of VOCs in Viola tianschanica. A 22-gauge stainless steel, triple-bed needle packed with Tenax, Carbopack X and Carboxen 1000 sorbents was used for analysis of VOCs in the herb. Furthermore, different parameters affecting the extraction efficiency and capacity were studied. RESULTS: The peak capacity obtained by NTDs was 104, more efficient than those of the static headspace (46) and hydrodistillation (93). This NTD method shows potential to trap a wide range of VOCs including the lower and higher volatile components, while the static headspace and hydrodistillation only detects lower volatile components, and semi-volatile and higher volatile components, respectively. CONCLUSION: The developed NTD sample preparation method is a more rapid, simpler, convenient, and sensitive extraction/desorption technique for analysis of VOCs in herbal medicines than the conventional methods such as static headspace and hydrodistillation.

AB - BACKGROUND & AIM: Search for an effective therapy for patients with hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) remains an important issue. This study investigated the efficacy of umbilical cord-derived mesenchymal stem cell (UC-MSC) transplantation in patients with HBV-ACLF. METHODS: 45 consecutive entecavir-treated HBV-ACLF patients were prospectively studied. Among these patients, 11 received both plasma exchange (PE) and a single transplantation of UC-MSCs (group A), while 34 received only PE (group B). The primary endpoint was survival at 24 months. RESULTS: Compared with group B, levels of albumin, alanine aminotransferase, aspartate aminotransferase, total bilirubin, direct bilirubin, prothrombin time (PT), international normalized ratio (INR) and model for end-stage liver disease score in group A improved significantly at 4 weeks after transplantation (p < 0.05). Levels of albumin, PT and INR in group A were also markedly improved at 24 months (p < 0.05). Group A had significantly higher cumulative survival rate at 24 months (54.5 % v.s. 26.5 %, p = 0.015 by log rank test). Between the two groups, levels of creatinine, White blood cell, hemoglobin and platelet were similar. HBeAg loss and hepatocellular carcinoma incidence were similar at 24 months. Group assignment (relative risk: 2.926, 95%confidence interval: 1.043-8.203, p = 0.041) was an independent predictor for survival at 24 months. Success rate of UC-MSC transplantation was 100 % in group A. No severe adverse event was observed in any patient. CONCLUSION: UC-MSC transplantation is safe and effective for HBV-ACLF patients treated with PE and entecavir. It further improves the hepatic function and survival.

AB - Pollen-pistil interactions are a fundamental process in the reproductive biology of angiosperms and play a particularly important role in maintaining incipient species that exist in sympatry. However, the majority of previous studies have focused on species with syncarpous gynoecia (fused carpels) and not those with apocarpous gynoecia (unfused carpels). In the present study, we investigated the growth of conspecific pollen tubes compared to heterospecific pollen tubes in Sagittaria species, which have apocarpous gynoecia. We conducted controlled pollinations between S. pygmaea and S. trifolia and observed the growth of conspecific and heterospecific pollen tubes under a fluorescence microscope. Heterospecific and conspecific pollen tubes arrived at locules within the ovaries near simultaneously. However, conspecific pollen tubes entered into the ovules directly, whereas heterospecific tubes passed through the carpel base and adjacent receptacle tissue, to ultimately fertilize other unfertilized ovules. This longer route taken by heterospecific pollen tubes therefore caused a delay in the time required to enter into the ovules. Furthermore, heterospecific pollen tubes displayed similar growth patterns at early and peak pollination. The growth pattern of heterospecific pollen tubes at late pollination was similar to that of conspecific pollen tubes at peak pollination. Heterospecific and conspecific pollen tubes took different routes to fertilize ovules. A delayed entry of heterospecific pollen into ovules may be a novel mechanism of conspecific pollen advantage (CPA) for apocarpous species.

AB - Repairing large calvarial bone defects remains a challenging task. Previously, it was discovered that that miR-148b, when acting in concert with bone morphogenetic protein 2 (BMP-2), enhanced the osteogenesis of human adipose-derived stem cells (hASCs) and improved calvarial bone healing in nude mice. However, the molecular target of miR-148b remained elusive. Here it is revealed that miR-148b directly targets NOG, whose gene product (noggin) is an antagonist to BMPs and negatively regulates BMP-induced osteogenic differentiation and bone formation. A new Cre/loxP-based baculovirus system was employed to drive prolonged BMP-2 and miR 148b overexpression in hASCs, wherein the BMP-2 overexpression induced noggin expression but the concurrent miR-148b expression downregulated noggin, thus relieving the negative regulatory loop and ameliorating hASC osteogenesis without hindering hASC proliferation or triggering appreciable cytotoxicity. Implantation of the engineered hASCs coexpressing BMP-2 and miR-148b into nude mice enabled substantial repair of critical-size calvarial bone defects (4 mm diameter) at 12 weeks post-transplantation, filling 83% of the defect area, 75% of bone volume and restoring the bone density to 89% of the original bone density. Such superior healing effects indicate the potential of the Cre/loxP-based baculovirus-mediated BMP-2/miR-148b expression for calvarial bone repair. Copyright (c) 2016 John Wiley & Sons, Ltd.

The objective was to review history, educational and training pathways, licensure and board certification, practice and compensation, and unique aspects of, or challenges faced by, neuropsychology in mainland China. METHOD: Historical, scientific, and clinical literatures were reviewed and integrated. RESULTS: The history of neuropsychology in mainland China is traced back to the late 1930s. Educational pathways have not yet been fully formalized. Clinical practice generally occurs within rehabilitation settings, and medical license is required. The main challenge lies in the establishment of training guidelines and the expansion of neuropsychology to meet the tremendous needs of a large nation. CONCLUSIONS: Although the development and status of psychology has gradually gained momentum in mainland China, the development of neuropsychology has not shown significant advancement since the late 1930s.

AB - OBJECTIVE: Many skin flaps have been described for fingertip reconstruction; however, they have not been compared histologically. The aim of this study is to compare the histological features of common insensate flaps that are used for fingertip reconstruction. METHOD: Skin from fingertips and common flap donor sites on the hand and forearm of cadavers were harvested. This study investigated four histological characteristics, namely thickness of the epidermis and dermis; the ratio of collagen to elastic fibres (C/E ratio) in subdermal tissues, and distribution densities of Merkel cells and Meissner's corpuscles. It then compared the values obtained to determine which flap donor site best matched the fingertip. RESULTS: Epidermal thickness of the reverse digital artery island flap, thenar flap, and hypothenar flap was similar to that of fingertip tissue; dermal thickness of the hypothenar flap was similar to that of fingertip tissue. The C/E ratio of the reverse digital artery island flap was similar to that of fingertip tissue. Merkel cells were abundant in the reverse digital artery island flap, but Meissner's corpuscles were few in each of the flaps compared with fingertip tissue. CONCLUSION: The flap donor site with histological properties most similar to fingertip tissue was the palmar lateral aspect at the finger base, representative of the reverse digital artery island flap with respect to epidermal thickness, C/E ratio, and presence of Merkel cells. The thenar and hypothenar flaps also showed similar properties.

PMID- 27687799 TI - What is the probability of replicating a statistically significant association in genome-wide association studies? AB - The goal of genome-wide association studies (GWASs) is to discover genetic variants associated with diseases/traits. Replication is a common validation method in GWASs. We regard an association as true finding when it shows significance in both primary and replication studies. A question worth pondering is what is the probability of a primary association (i.e. a statistically significant association in the primary study) being validated in the replication study? This article systematically reviews the answers to this question from different points of view. As Bayesian methods can help us integrate out the uncertainty about the underlying effect of the primary association, we will mainly focus on the Bayesian view in this article. We refer the Bayesian replication probability as the replication rate (RR). We further describe an estimation method for RR, which makes use of the summary statistics from the primary study. We can use the estimated RR to determine the sample size of the replication study and to check the consistency between the results of the primary study and those of the replication study. We describe an R-package to estimate and apply RR in GWASs. Simulation and real data experiments show that the estimated RR has good prediction and calibration performance. We also use these data to demonstrate the usefulness of RR. The R-package is available at http://bioinformatics.ust.hk/RRate.html. PMID- 27687800 TI - Participation of peripheral TRPV1, TRPV4, TRPA1 and ASIC in a magnesium sulfate induced local pain model in rat. AB - We previously showed that magnesium sulfate (MS) has systemic antinociceptive and local peripheral pronociceptive effects. The role of transient receptor potential (TRP) channels and acid-sensing ion channels (ASICs) in the mechanism of action of MS has not been investigated in detail. The aim of this study was to explore the participation of TRP channels in the pronociceptive action of MS in rats after its intraplantar injection. The paw withdrawal threshold (PWT) to mechanical stimuli was measured by the electronic von Frey test. Drugs that were tested were either co-administered with an isotonic pH-unadjusted or pH-adjusted solution of MS intraplantarily, or to the contralateral paw to exclude systemic effects. We found that the subcutaneous administration of both pH-adjusted (7.4) and pH-unadjusted (about 6.0) isotonic (6.2% w/v in water) solutions of MS induce the pain at the injection site. The pH-unadjusted MS solution-induced mechanical hyperalgesia decreased in a dose-dependent manner as a consequence of co injection of capsazepine, a selective TRPV1 antagonist (20, 100 and 500pmol/paw), RN-1734, a selective TRPV4 antagonist (1.55, 3.1 and 6.2MUmol/paw), HC-030031, a selective TRPA1 antagonist (5.6, 28.1 and 140nmol/paw), and amiloride hydrochloride, a non-selective ASIC inhibitor (0.83, 2.5 and 7.55MUmol/paw). In pH-adjusted MS-induced hyperalgesia, the highest doses of TRPV1, TRPV4 and TRPA1 antagonists displayed effects that were, respectively, either similar, less pronounced or delayed in comparison to the effect induced by administration of the pH-unadjusted MS solution; the ASIC antagonist did not have any effect. These results suggest that the MS-induced local peripheral mechanical hyperalgesia is mediated via modulation of the activity of peripheral TRPV1, TRPV4, TRPA1 and ASICs. Specific local inhibition of TRP channels represents a novel approach to treating local injection-related pain. PMID- 27687801 TI - Exposure to alcohol during adolescence exerts long-term effects on stress response and the adult brain stress circuits. AB - The hypothalamic-pituitary-adrenal (HPA) axis undergoes critical developments during adolescence. Therefore, stressors experienced during this period potentially have long-term effects on adult HPA axis function. We hypothesized that adolescent intermittent ethanol (AIE) exposure would affect adult HPA axis function, resulting in altered responses to an alcohol challenge in young adults or adults. To test these hypotheses, male rats were exposed to alcohol vapor for 6h per day from post-natal day (PND) 28-42, then acutely challenged with alcohol intragastrically (3.2-4.5g/kg) in young adults (PND 70) or adults (PND 90). Overall, we observed blunted HPA axis responses to an alcohol challenge due to AIE exposure. Specifically, AIE tended to inhibit the alcohol challenge-induced increase in plasma corticosterone (CORT) concentrations in young adult and adult rats. As well, AIE significantly blunted the alcohol challenge-induced arginine vasopressin (Avp) mRNA expression in the paraventricular nucleus (PVN) of the hypothalamus of adult rats. Results of the present study are similar to what we have previously shown, that these changes in PVN responsiveness may result from AIE-induced alterations in adrenergic neurons in brain stem regions C1-C3 known to project to the PVN. AIE elevated the number of colocalized c fos/phenylethanolamine N-methyltransferase (PNMT)-positive cell bodies in the C1 region of adult rats. Together, these data suggest that AIE exposure produces alterations in male HPA axis responsiveness to administration of an acute alcohol challenge that may be long-lasting. PMID- 27687802 TI - State-dependent variability of dynamic functional connectivity between frontoparietal and default networks relates to cognitive flexibility. AB - The brain is a dynamic, flexible network that continuously reconfigures. However, the neural underpinnings of how state-dependent variability of dynamic functional connectivity (vdFC) relates to cognitive flexibility are unclear. We therefore investigated flexible functional connectivity during resting-state and task-state functional magnetic resonance imaging (rs-fMRI and t-fMRI, resp.) and performed separate, out-of-scanner neuropsychological testing. We hypothesize that state dependent vdFC between the frontoparietal network (FPN) and the default mode network (DMN) relates to cognitive flexibility. Seventeen healthy subjects performed the Stroop color word test and underwent t-fMRI (Stroop computerized version) and rs-fMRI. Time series were extracted from a cortical atlas, and a sliding window approach was used to obtain a number of correlation matrices per subject. vdFC was defined as the standard deviation of connectivity strengths over these windows. Higher task-state FPN-DMN vdFC was associated with greater out-of-scanner cognitive flexibility, while the opposite relationship was present for resting-state FPN-DMN vdFC. Moreover, greater contrast between task-state and resting-state vdFC related to better cognitive performance. In conclusion, our results suggest that not only the dynamics of connectivity between these networks is seminal for optimal functioning, but also that the contrast between dynamics across states reflects cognitive performance. PMID- 27687804 TI - Gemcitabine reduces MDSCs, tregs and TGFbeta-1 while restoring the teff/treg ratio in patients with pancreatic cancer. AB - BACKGROUND: Cancer immunotherapy can be potentiated by conditioning regimens such as cyclophosphamide, which reduces the level of regulatory T cells (tregs). However, myeloid suppressive cells are still remaining. Accordingly to previous reports, gemcitabine improves immune status of cancer patients. In this study, the role of gemcitabine was further explored to map its immunological target cells and molecules in patients with pancreatic cancer. METHODS: Patient blood was investigated by flow cytometry and cytokine arrays at different time points during gemcitabine treatment. RESULTS: The patients had elevated myeloid-derived suppressor cells (MDSCs), and Tregs at diagnosis. Myeloid cells were in general decreased by gemcitabine. The granulocytic MDSCs were significantly reduced while monocytic MDSCs were not affected. In vitro, monocytes responding to IL-6 by STAT3 phosphorylation were prevented to respond in gemcitabine medium. However, gemcitabine could not prevent STAT3 phosphorylation in IL-6-treated tumor cell lines. TGFbeta-1 was significantly reduced after only one treatment and continued to decrease. At the same time, the effector T cell:Treg ratio was increased and the effector T cells had full proliferative capacity during the gemcitabine cycle. However, after a resting period, the level of suppressor cells and TGFbeta 1 had been restored showing the importance of continuous conditioning. CONCLUSIONS: Gemcitabine regulates the immune system in patients with pancreatic cancer including MDSCs, Tregs and molecules such as TGFbeta-1 but does not hamper the ability of effector lymphocytes to expand to stimuli. Hence, it may be of high interest to use gemcitabine as a conditioning strategy together with immunotherapy. PMID- 27687805 TI - A Prospective Randomized Clinical Trial in Total Hip Arthroplasty-Comparing Early Results Between the Direct Anterior Approach and the Posterior Approach. AB - BACKGROUND: We report a prospective randomized study comparing early clinical results between the direct anterior approach (DAA) and posterior approach (PA) in primary hip arthroplasty. METHODS: Surgeries were performed by 2 senior hip arthroplasty surgeons. Seventy-two patients with complete data were assessed preoperatively 2, 6, and 12 weeks postoperatively. The primary outcomes were the Western Ontario McMasters Arthritis Index and Oxford Hip Scores. Secondary outcome measures included the EuroQoL, 10-meter walk test, and clinical and radiographic parameters. RESULTS: Data analyses showed no difference between DAA (n = 35) and PA (n = 37) groups when comparing total scores for primary outcomes. No significant differences were observed for 10-meter walk test, EuroQoL, and radiographic analyses. Subgroup analysis for surgeon 1 identified that the DAA group had shorter acute hospital stay, less postoperative opiate requirements, and smaller wounds. However, this was offset by increased operative time, higher intraoperative blood loss, and weaker hip flexion at 2 and 6 weeks. Subgroup analysis of items on the Western Ontario McMasters Arthritis Index and Oxford Hip Score identified that hip flexion activity favored the DAA group up to 6 weeks postoperatively. There was an 83% incidence of lateral cutaneous nerve of thigh neuropraxia at the 12-week mark in the DAA group. No neuropraxias occurred in the PA group. One dislocation occurred in each group. A single patient from the DAA group required reoperation for leg-length discrepancy. CONCLUSION: DAA total hip arthroplasty (THA) has comparable results with PA THA. Choice of surgical approach for THA should be based on patient factors, surgeon preference, and experience. PMID- 27687806 TI - Do Conversion Total Hip Arthroplasty Yield Comparable Results to Primary Total Hip Arthroplasty? AB - BACKGROUND: The incidence of hip fractures is growing with the increasing elderly population. Typically, hip fractures are treated with open reduction internal fixation, hemiarthroplasty, or total hip arthroplasty (THA). Failed hip fracture fixation is often salvaged by conversion THA. The total number of conversion THA procedures is also supplemented by its use in treating different failed surgical hip treatments such as acetabular fracture fixation, Perthes disease, slipped capital femoral epiphysis, and developmental dysplasia of the hip. As the incidence of conversion THA rises, it is important to understand the perioperative characteristics of conversion THA. Some studies have demonstrated higher complication rates in conversion THAs than primary THAs, but research distinguishing the 2 groups is still limited. METHODS: Perioperative data for 119 conversion THAs and 251 primary THAs were collected at 2 centers. Multivariable linear regression was performed for continuous variables, multivariable logistic regression for dichotomous variables, and chi-square test for categorical variables. RESULTS: Outcomes for conversion THAs were significantly different (P < .05) compared to primary THA and had longer hospital length of stay (average 3.8 days for conversion THA, average 2.8 days for primary THA), longer operative time (168 minutes conversion THA, 129 minutes primary THA), greater likelihood of requiring metaphysis/diaphysis fixation, and greater likelihood of requiring revision type implant components. CONCLUSION: Our findings suggest that conversion THAs require more resources than primary THAs, as well as advanced revision type components. Based on these findings, conversion THAs should be reclassified to reflect the greater burden borne by treatment centers. PMID- 27687807 TI - Drivers of the Variation in Prosthetic Implant Purchase Prices for Total Knee and Total Hip Arthroplasties. AB - BACKGROUND: Previous studies have documented wide variation in health care spending and prices; however, the causes for the variation in supply purchase prices across providers are not well understood. The purpose of this study was to determine the drivers of variation in prosthetic implant purchase prices for primary total knee and hip arthroplasties (TKA and THA, respectively) across providers. METHODS: We obtained retrospective data from 27 hospitals on the average prosthetic implant purchase prices for primary TKAs and THAs over the 12 months ending September 30, 2013, as well as data on a range of independent potential explanatory variables. Each hospital performed at least 200 primary total joint arthroplasties per year. The multivariate seemingly unrelated regression approach was used to evaluate the impact of the variables on purchase price for each type of implant. RESULTS: The average purchase price at the hospital at the 90th percentile was 2.1 times higher for TKAs and 1.7 times higher for THAs than that at the hospital at the 10th percentile. The use of a hospital-physician committee for implant vendor selection and negotiation was associated with 17% and 23% lower implant purchase prices (P < .05) for TKAs and THAs, respectively, relative to hospitals that did not have this collaborative approach. CONCLUSION: The use of a joint hospital-physician committee is a potential strategy for achieving lower average purchase prices for prosthetic implants. Policies to increase hospital-physician collaboration may lead to lower average purchase prices in this market. PMID- 27687803 TI - Insight from animal models of environmentally driven epigenetic changes in the developing and adult brain. AB - The efforts of many neuroscientists are directed toward understanding the appreciable plasticity of the brain and behavior. In recent years, epigenetics has become a core of this focus as a prime mechanistic candidate for behavioral modifications. Animal models have been instrumental in advancing our understanding of environmentally driven changes to the epigenome in the developing and adult brain. This review focuses mainly on such discoveries driven by adverse environments along with their associated behavioral outcomes. While much of the evidence discussed focuses on epigenetics within the central nervous system, several peripheral studies in humans who have experienced significant adversity are also highlighted. As we continue to unravel the link between epigenetics and phenotype, discerning the complexity and specificity of epigenetic changes induced by environments is an important step toward understanding optimal development and how to prevent or ameliorate behavioral deficits bred by disruptive environments. PMID- 27687808 TI - The Influence of Cement Morphology Parameters on the Strength of the Cement-Bone Interface in Tibial Tray Fixation. AB - BACKGROUND: The strength of the cement-bone interface in tibial component fixation depends on the morphology of the cement mantle. The purpose of this study was to identify thresholds of cement morphology parameters to maximize fixation strength using a minimum amount of cement. METHODS: Twenty-three cadaveric tibiae were analyzed that had been implanted with tibial trays in previous studies and for which the pull-out strength of the tray had been measured. Specimens were separated into a group failing at the cement-bone interface (INTERFACE) and one failing in the bulk bone (BULK). Maximum pull-out strength corresponds to the ultimate strength of the bulk bone if the cement-bone interface is sufficiently strong. 3D models of the cement mantle in situ were reconstructed from computed tomography scans. The influences of bone mineral density and 6 cement morphology parameters (reflecting cement penetration, bone cement interface, cement volume) on pull-out strength of the BULK group were determined using multiple regression analysis. The threshold of each parameter for classification of the specimens into either group was determined using receiver operating characteristic analysis. RESULTS: Cement penetration exceeding a mean of 1.1 mm or with a maximum of 5.6 mm exclusively categorized all BULK bone failure specimens. Failure strength of BULK failure specimens increased with bone mineral density (R2 = 0.67, P < .001) but was independent of the cement morphology parameters. CONCLUSION: To maximize fixation strength, a mean cement penetration depth of at least 1.1 mm should be achieved during tibial tray cementing. PMID- 27687809 TI - Management of Vancouver B2 and B3 Periprosthetic Proximal Femoral Fractures by Distal Locking Femoral Stem (Cannulok) in Patients 75 Years and Older. AB - BACKGROUND: Periprosthetic fracture following total hip arthroplasty is a significant problem faced by hip surgeons, and its management in elderly patients remains a considerable challenge. METHODS: We retrospectively reviewed 28 Vancouver B2 and B3 periprosthetic femoral fractures (PFF) treated with revision of the femoral stems by distally locked, hydroxyapatite-coated uncemented stems (Cannulok). Patients were aged 75 years or older at the time of surgery. RESULTS: The mean follow-up was 44.6 months (range, 24-102). The mean postoperative Oxford hip score was 30.1 (range, 10-46). The rate of fracture union was 95.8%, and the survivorship of the stem was 100% at the end of follow-up. CONCLUSION: The management of PFF in elderly is associated with increased postoperative morbidity and mortality. The use of a distally locked, hydroxyapatite-coated femoral stem is a valid option for the treatment of PFF to achieve fracture union with a low rate of revision. PMID- 27687810 TI - Bone Remodeling in Acetabular Reconstruction Using a Kerboull-Type Reinforcement Device and Structural Bone-Grafting in Total Hip Arthroplasty. AB - BACKGROUND: The purpose of this study was to identify the long-term durability of the Kerboull-type reinforcement device (KT plate) in acetabular reconstruction for massive bone defects, assessing the remodeling of structural bone grafts. METHODS: This study retrospectively evaluated 106 hips that underwent acetabular reconstruction using a KT plate between November 2000 and December 2010. Thirty eight primary total hip arthoplasties (THAs) and 68 revised THAs were performed, and the mean duration of clinical follow-up was 8 years (5-14 years). Regarding reconstructing the acetabular bone defects, autografts were used in 37 hips, allografts in 68 hips, and A-W glass ceramics in 2 hips. RESULTS: One hip exhibited radiological migration and no revision for aseptic loosening. The mean Merle d'Aubigne Clinical Score improved from 7.5 points (4-12 points) preoperatively to 10.9 points (9-18 points) at the last follow-up. The Kaplan Meier survival rate for radiological migration of primary and revised THAs at 10 years was 100% and 97% (95% confidence interval: 96%-100%), respectively. Bone remodeling was evaluated using the radiological demarcation at the bone-to-bone interface, and an improvement of 100% in primary THAs and 94% in revised THAs was observed. CONCLUSION: For massive bone defects, acetabular reconstruction using the KT plate with a structural bone grafting can yield successful results. PMID- 27687813 TI - Recognizing "Bella Swan" and "Hermione Granger": No Own-Race Advantage in Recognizing Photos of Famous Faces. AB - We investigated recognition of familiar and unfamiliar own- and other-race faces across natural variability in appearance. Participants sorted 20 photographs of each of two identities into piles such that each pile contained all photographs of a single identity. The other-race effect was limited to unfamiliar faces. When faces were unfamiliar, participants perceived more identities when sorting other race races; when faces were familiar, participants made two piles for both own- and other-race faces. Our work calls for rethinking the concept of the other-race effect. PMID- 27687812 TI - Self-Ratings of Olfactory Performance and Odor Annoyance Are Associated With the Affective Impact of Odor, but Not With Smell Test Results. AB - Our aim was to explore factors potentially associated with subjective (self rated) and objective (measured using the Sniffin' Sticks Extended test) olfactory performance in the general population without olfactory disorders. We studied associations between olfactory performance and how important odors were in determining liking for new places, things, and people (measured using the Affective Impact of Odor scale) and the average annoyance caused by odors in 117 adults (83 women, 34 men; age 18-69 years, mean age 32 years). In a subset of 44 participants, we also studied associations between olfactory performance and spice odor identification task scores (14 odors) and the number of herbs and spices consumed. Self-rated olfactory acuity and odor-related annoyance were associated with the Affective Impact of Odor scores, but neither correlated with the smell test results. Instead, the number of spices consumed correlated with spice odor identification score ( r = .50) and the identification (but not threshold nor discrimination) subscore of the Sniffin' Sticks test ( r = .49). Our results suggest that a tendency to perceive odors in affective terms may be associated with overestimation of olfactory abilities and that recurrent exposure to a large variety of spice odors may improve performance on odor identification. PMID- 27687811 TI - Dyslipidemia: Obese or Not Obese-That Is Not the Question. AB - PURPOSE OF REVIEW: Purpose of review: It is becoming increasingly clear that some obese individuals do not develop dyslipidemia and instead remain healthy, while some normal weight individuals become dyslipidemic and unhealthy. RECENT FINDINGS: The present review examines the similarities and differences between healthy and unhealthy individuals with and without obesity and discusses putative underlying mechanisms of dyslipidemia. The presence of dyslipidemia and compromised metabolic health in both lean and obese individuals suggests that the obese phenotype per se does not represent a main independent risk factor for the development of dyslipidemia and that dyslipidemia, rather than obesity, may be the driver of metabolic diseases. Notably, adipose tissue dysfunction and ectopic lipid deposition, in particular in the liver, seems a common trait of unhealthy individuals. PMID- 27687815 TI - Capecitabine and Oxaliplatin Prior and Concurrent to Preoperative Pelvic Radiotherapy in Patients With Locally Advanced Rectal Cancer: Long-Term Outcome. AB - BACKGROUND: The risk/benefit ratio of any treatment can only be fully assessed if long-term results of both efficacy and toxicity are taken into account. Whereas the combined modality treatment of locally advanced rectal cancer (LARC) has considerably improved prognosis, particularly with regard to local control, long term results-including patient-reported outcomes-are underreported. PATIENTS AND METHODS: Patients with LARC treated within a multicenter single-arm phase II study were prospectively assessed for at least 5 years after surgery. Study treatment consisted of capecitabine and oxaliplatin prior and concurrent to preoperative pelvic radiotherapy followed by total mesorectal excision. Progression-free survival time (first endpoint), overall survival time, and pattern of relapse were analyzed in the whole study population and in pre-planned exploratory subgroups. Patient-reported outcomes, including overall satisfaction with bowel, stoma, and urinary function, were assessed in 6-month intervals. RESULTS: Five-year progression-free and overall survival rate was 61% (95% confidence interval [CI], 46%-73%) and 78% (95% CI, 63%-87%), respectively. Distant to local recurrence rate was 3:1, with only 8% of patients relapsing locally. Main predictors for recurrence in univariate analyses were tumor downstaging (hazard ratio, 0.16; 95% CI, 0.05-0.56; P = .0011) and nodal downstaging (hazard ratio, 0.17; 95% CI, 0.06-0.52; P = .0005). The self-reported burden of symptoms related to bowel function was high in up to one-third of patients. A total of 28% of patients were dissatisfied with their urinary, bowel, or stoma function for at least 1 observation period. CONCLUSION: Combined modality treatment of LARC results in a high and durable local disease control rate, especially in patients with tumor and/or nodal downstaging, at the cost of relevant long-term toxicity. Long-term care is required for a proportion of patients with poor gastrointestinal and/or urinary function after multimodality therapy. Reporting of long-term follow-up, including patient-recorded outcomes should be mandatory for future trials in LARC. PMID- 27687816 TI - Upholding WAG/Rij rats as a model of absence epileptogenesis: Hidden mechanisms and a new theory on seizure development. AB - The WAG/Rij rat model has recently gathered attention as a suitable animal model of absence epileptogenesis. This latter term has a broad definition encompassing any possible cause that determines the development of spontaneous seizures; however, most of, if not all, preclinical knowledge on epileptogenesis is confined to the study of post-brain insult models such as traumatic brain injury or post-status epilepticus models. WAG/Rij rats, but also synapsin 2 knockout, Kv7 current-deficient mice represent the first examples of genetic models where an efficacious antiepileptogenic treatment (ethosuximide) was started before seizure onset. In this review, we have critically reconsidered all articles published regarding WAG/Rij rats, from the perspective that the period before SWD onset is considered as the latent period. In our new theory on seizure development, it is proposed that genes might be considered as the initial 'insult' responsible for all plastic changes underpinning the development of spontaneous seizures. According to this idea, in WAG/Rij rats, genetic predisposition would lead to the development of abnormal bilateral cortical epileptic foci, which would then non-genetically stimulate the rest of the brain to rearrange networks in order to phenotypically develop seizures similarly to what happens during electrical kindling. PMID- 27687814 TI - The Olfactory Mosaic: Bringing an Olfactory Network Together for Odor Perception. AB - Olfactory perception and its underlying neural mechanisms are not fixed, but rather vary over time, dependent on various parameters such as state, task, or learning experience. In olfaction, one of the primary sensory areas beyond the olfactory bulb is the piriform cortex. Due to an increasing number of functions attributed to the piriform cortex, it has been argued to be an associative cortex rather than a simple primary sensory cortex. In fact, the piriform cortex plays a key role in creating olfactory percepts, helping to form configural odor objects from the molecular features extracted in the nose. Moreover, its dynamic interactions with other olfactory and nonolfactory areas are also critical in shaping the olfactory percept and resulting behavioral responses. In this brief review, we will describe the key role of the piriform cortex in the larger olfactory perceptual network, some of the many actors of this network, and the importance of the dynamic interactions among the piriform-trans-thalamic and limbic pathways. PMID- 27687817 TI - The link between autoimmune diseases and obsessive-compulsive and tic disorders: A systematic review. AB - Immunological factors are increasingly recognized as being important in a range of neuropsychiatric disorders. We aimed to summarize the disperse and often conflicting literature on the potential association between autoimmune diseases (ADs) and obsessive-compulsive disorder (OCD) and tic disorders. We searched PubMed, EMBASE, and PsycINFO for original studies evaluating the relationship between ADs and OCD/tic disorders until July, 13th 2016. Seventy-four studies met inclusion criteria. Overall, the studies were of limited methodological quality. Rates of OCD were higher in rheumatic fever patients who were also affected by its neurological manifestation, Sydenham's chorea. The literature on other ADs was scarce and the findings inconclusive. Few studies examined the association between ADs and tic disorders. A handful of family studies reported elevated rates of ADs in first-degree relatives of individuals with OCD/tic disorders, and vice versa, potentially suggesting shared genetic and/or environmental mechanisms. In conclusion, at present, there is modest evidence for a possible association and familial co-aggregation between ADs and OCD/tic disorders. We offer some suggestions for future research. PMID- 27687818 TI - Feelings of shame, embarrassment and guilt and their neural correlates: A systematic review. AB - This systematic review aimed to provide a comprehensive summary of the current literature on the neurobiological underpinnings of the experience of the negative moral emotions: shame, embarrassment and guilt. PsycINFO, PubMed and MEDLINE were used to identify existing studies. Twenty-one functional and structural magnetic resonance imaging and positron emission tomography studies were reviewed. Although studies differed considerably in methodology, their findings highlight both shared and distinct patterns of brain structure/function associated with these emotions. Shame was more likely to be associated with activity in the dorsolateral prefrontal cortex, posterior cingulate cortex and sensorimotor cortex; embarrassment was more likely to be associated with activity in the ventrolateral prefrontal cortex and amygdala; guilt was more likely to be associated with activity in ventral anterior cingulate cortex, posterior temporal regions and the precuneus. Although results point to some common and some distinct neural underpinnings of these emotions, further research is required to replicate findings.

PMID- 27687820 TI - Solifenacin in Children and Adolescents with Overactive Bladder: Results of a Phase 3 Randomised Clinical Trial. AB - BACKGROUND: Solifenacin, an effective, well-tolerated treatment for adult overactive bladder (OAB) symptoms, has not been evaluated in placebo-controlled paediatric clinical trials. OBJECTIVES: To evaluate the efficacy and safety of once-daily oral solifenacin suspension in OAB patients aged 5-<12 yr (children) and 12-<18 yr (adolescents). DESIGN, SETTING, AND PARTICIPANTS: The study involved a 4-wk urotherapy run-in followed by 1:1 randomisation to 12-wk double blind solifenacin or placebo treatment alongside urotherapy. INTERVENTION: Solifenacin paediatric equivalent doses (PEDs) of adult doses: 2.5mg, 5mg, 7.5mg, and 10mg. The starting dose was PED 5mg; all patients were titrated to an optimum dose at 3-wk intervals over 9 wk, resulting in >=3 wk at the optimum dose before end of treatment (EoT). OUTCOME MEASUREMENTS AND STATISTICS: Superiority of solifenacin versus placebo in change from baseline to EoT for mean volume voided/micturition (MVV, primary endpoint); daytime maximum volume voided/micturition (DMaxVV); incontinence episodes (mean/24h); mean number of incontinence-free days or nights/7 d; micturition frequency; and Micturition frequency adjusted for baseline total voided volume (VTB) as an exploratory parameter). Efficacy parameters were analysed using analysis of covariance. Safety parameters (treatment-emergent adverse events, serious adverse events, laboratory variables, vital signs, electrocardiogram, postvoid residual volume) are summarised using descriptive statistics. RESULTS AND LIMITATIONS: In children, solifenacin was superior to placebo in terms of the change from baseline to EoT for MVV (solifenacin-placebo difference 12.1ml, 95% confidence interval [CI] 0.2-24.0; p=0.046), DMaxVV (difference in adjusted mean change from baseline for solifenacin-placebo 31.9ml, 95% CI 4.3-59.5; p=0.024), VTB-adjusted micturition frequency (p=0.028). Other endpoints were not significantly different. Solifenacin was well tolerated. For adolescents, it was not possible to draw firm efficacy conclusions because of the low numbers recruited. CONCLUSIONS: Once-daily solifenacin oral suspension in children with OAB was superior to placebo for MVV (primary efficacy endpoint) and was well tolerated. PATIENT SUMMARY: In this 12-wk study, a once-daily oral suspension of solifenacin in children aged 5-<12 yr with overactive bladder was superior to placebo in increasing mean volume voided/micturition, the primary efficacy variable in the study. Solifenacin was well tolerated, with a low incidence of dry mouth and constipation. This study is registered at ClinicalTrials.gov as NCT01565707. PMID- 27687821 TI - Systematic Review of the Performance of Noninvasive Tests in Diagnosing Bladder Outlet Obstruction in Men with Lower Urinary Tract Symptoms. AB - CONTEXT: Several noninvasive tests have been developed for diagnosing bladder outlet obstruction (BOO) in men to avoid the burden and morbidity associated with invasive urodynamics. The diagnostic accuracy of these tests, however, remains uncertain. OBJECTIVE: To systematically review available evidence regarding the diagnostic accuracy of noninvasive tests in diagnosing BOO in men with lower urinary tract symptoms (LUTS) using a pressure-flow study as the reference standard. EVIDENCE ACQUISITION: The EMBASE, MEDLINE, Cochrane Database of Systematic Reviews, Cochrane Central, Google Scholar, and WHO International Clinical Trials Registry Platform Search Portal databases were searched up to May 18, 2016. All studies reporting diagnostic accuracy for noninvasive tests for BOO or detrusor underactivity in men with LUTS compared to pressure-flow studies were included. Two reviewers independently screened all articles, searched the reference lists of retrieved articles, and performed the data extraction. The quality of evidence and risk of bias were assessed using the QUADAS-2 tool. EVIDENCE SYNTHESIS: The search yielded 2774 potentially relevant reports. After screening titles and abstracts, 53 reports were retrieved for full-text screening, of which 42 (recruiting a total of 4444 patients) were eligible. Overall, the results were predominantly based on findings from nonrandomised experimental studies and, within the limits of such study designs, the quality of evidence was typically moderate across the literature. Differences in noninvasive test threshold values and variations in the urodynamic definition of BOO between studies limited the comparability of the data. Detrusor wall thickness (median sensitivity 82%, specificity 92%), near-infrared spectroscopy (median sensitivity 85%, specificity 87%), and the penile cuff test (median sensitivity 88%, specificity 75%) were all found to have high sensitivity and specificity in diagnosing BOO. Uroflowmetry with a maximum flow rate of <10ml/s was reported to have lower median sensitivity and specificity of 68% and 70%, respectively. Intravesical prostatic protrusion of >10mm was reported to have similar diagnostic accuracy, with median sensitivity of 68% and specificity of 75%. CONCLUSIONS: According to the literature, a number of noninvasive tests have high sensitivity and specificity in diagnosing BOO in men. However, although the majority of studies have a low overall risk of bias, the available evidence is limited by heterogeneity. While several tests have shown promising results regarding noninvasive assessment of BOO, invasive urodynamics remain the gold standard. PATIENT SUMMARY: Urodynamics is an accurate but potentially uncomfortable test for patients in diagnosing bladder problems such as obstruction. We performed a thorough and comprehensive review of the literature to determine if there were less uncomfortable but equally effective alternatives to urodynamics for diagnosing bladder problems. We found that some simple tests appear to be promising, although they are not as accurate. Further research is needed before these tests are routinely used in place of urodynamics.

PMID- 27687824 TI - Dysphagia - Results from multivariable predictive modelling on aspiration from a subset of the ARTSCAN trial. AB - PURPOSE: To establish predictive models for late objective aspiration and late patient-reported choking based on dose-volume parameters and baseline patient and treatment characteristics, for patients with head and neck cancer undergoing definitive radiotherapy (RT). The impact of electively treated volume on late aspiration was also investigated. METHODS AND MATERIAL: This prospective cohort is a subsample of 124 survivors from the ARTSCAN study. Late aspiration was identified with videofluoroscopy, at a minimum of 25months after the start of RT. Patient-reported choking was analysed at 12 and 60months post RT using the EORTC Quality of Life Module for Head and Neck Cancer 35. Univariable and multivariable analyses were performed to describe the association between clinical factors and dose-volume descriptors for organs at risk (OARs) and late dysphagia. RESULTS: Aspiration was found in 47% of the eligible patients. Mean dose to the middle pharyngeal constrictor (MPC), neck dissection post RT and age at randomisation in ARTSCAN were associated to late aspiration. Mean dose to the superior pharyngeal constrictor (SPC) and swallowing complaints at baseline were associated to patient reported choking at both time-points. CONCLUSIONS: Three separate risk groups for late aspiration, and two risk groups for late patient-reported choking were identified based on number of risk factors. The size of the electively treated volume could be used as a surrogate for individual OARs predicting late aspiration. PMID- 27687826 TI - An epistatic explanation. AB - Interactions between two gene variants that rarely cause midline craniosynostosis on their own make the development of the disorder a certainty. PMID- 27687823 TI - Quality of life and disability: can they be improved by active postoperative rehabilitation after spinal fusion surgery in patients with spondylolisthesis? A randomised controlled trial with 12-month follow-up. AB - PURPOSE: The aim of the study was to investigate the effectiveness of the postoperative 12-month exercise program compared to usual care on disability and health-related quality of life (HRQoL) in patients after lumbar spine fusion surgery (LSF). METHODS: Altogether, 98 patients with isthmic (31) or degenerative (67) spondylolisthesis were randomised to exercise therapy group (EG) (n = 48) or usual care group (UCG) (n = 50) 3 months after LSF. EG patients had home-based progressive strength and aerobic training program for 12 months. UCG patients received only oral and written instructions of exercises. Oswestry Disability Index (ODI) and HRQoL (RAND-36) were evaluated at the time of randomization, at the end of the intervention and 1 year after intervention. RESULTS: The mean ODI score decreased from 24 (12) to 18 (14) in the EG and from 18 (12) to 13 (11) in the UCG during intervention (between-groups p = 0.69). At 1-year follow-up, 25 % of the EG and 28 % of the UCG had an ODI score >=20. No between-group differences in HRQoL change were found at any time point. The mean (95 % CI) physical functioning dimension of the HRQoL improved by 10.0 (4.6-15.3) in the EG and by 7.8 (2.5-13.0) in the UCG. In addition, the role physical score improved by 20.0 (7.7-32.3) in the EG and by 16.4 (4.4-28.4) in the UCG during the intervention. CONCLUSIONS: The exercise intervention did not have an impact on disability or HRQoL beyond the improvement achieved by usual care. However, disability remained at least moderate in considerable proportion of patients. PMID- 27687825 TI - Fluorescent quantitative PCR detection of Mycobacterium tuberculosis in tissue sections from granulomatous lesions retrieved using EDTA. AB - AIMS: This study aimed to use EDTA to retrieve paraffin-embedded tissue sections of inflammatory granulomatous lesions and increase the detection rate of tuberculosis (TB)/non-tuberculous mycobacteria. Due to the influence of chemical reagents during the fixation process, the amplification of fluorescent quantitative PCR was blocked after DNA extraction, and the results were not ideal. METHODS: Special staining technologies (acid-fast and Auramine O) and fluorescent quantitative PCR were used to detect TB/non-tuberculous mycobacteria in 125 cases of inflammatory granulomatous lesions in paraffin-embedded tissue sections with and without EDTA retrieval. RESULTS: In 125 cases of inflammatory granulomatous lesions, 75 cases (60%) were positive for mycobacteria using fluorescent quantitative PCR without EDTA retrieval, of which 74 cases (59.2%) were detected with TB mycobacteria and 1 case (0.8%) with non-tuberculous mycobacteria. The average cycle threshold value of positive specimens ranged from 29 to 32 (30.5). However, 88 cases (70.4%) were positive for mycobacteria using fluorescent quantitative PCR with EDTA retrieval, of which 83 cases (66.4%) were detected with TB mycobacteria and 5 cases (4%) with non-tuberculous mycobacteria. The average Ct value of positive specimens ranged from 27 to 30 (28.0). Statistical differences were found between the two groups (p<0.05; p<0.01). CONCLUSIONS: This study showed that compared with special staining technologies (acid-fast and Auramine O) and molecular pathology detection, fluorescent quantitative PCR with EDTA retrieval could greatly improve the detection rate of TB/non-tuberculous mycobacteria and increase the sensitivity of the fluorescent quantitative PCR. PMID- 27687827 TI - Esophageal stricture after endoscopic submucosal dissection treated successfully by temporary stent placement. AB - The growing use of endoscopic submucosal dissection (ESD) has enabled the highly curative treatment of early esophageal cancer. The circumferential extent of the tumor is reportedly related to the frequency of post-treatment stricture, with postoperative esophageal stricture reported to occur frequently when the post resection mucosal defect exceeds 75 % of the esophageal luminal circumference. In some clinical cases, locally injected or orally administered steroids aimed at preventing post-treatment stricture fail to prevent re-stricture. Only two prior reports have investigated temporary stent placement for stricture after ESD for early esophageal cancer, and consensus is lacking on the appropriate duration and timing of stent placement. Here, we report our experience with a case of stricture after ESD for early esophageal cancer, in which temporary stent placement was effective for releasing the stricture for at least 6 months. PMID- 27687828 TI - Postmortem computed tomography findings in suicide victims. AB - Suicide is the eighth cause of mortality in France and the leading cause in people aged between 25 and 34 years. The most common methods of suicide are hanging, self-poisoning with medicines and firearms. Postmortem computed tomography (CT) is a useful adjunct to autopsy to confirm suicide and exclude other causes of death. At autopsy, fractures of the hyoid bone or thyroid cartilage, or both, are found in more than 50% of suicidal hangings. Cervical vertebra fractures are rare and only seen in suicide victims jumping from a great height. Three-dimensional reconstructions from CT data are useful to visualize the ligature mark on the neck. In suicides by firearm, postmortem CT shows entry and exit wounds, parenchymal lesions along the bullet path, as well as projectiles in case of penetrating trauma. However, in the chest and abdomen it is more difficult to identify the path of the projectile. Postmortem CT also shows specific features of suicide by drowning or stabbing, but its use is limited in cases of self-poisoning. The use of postmortem CT is also limited by decomposition and change of body position. This article presents the imaging features seen on postmortem CT according to the method of suicide. PMID- 27687829 TI - Contrast-enhanced spectral mammography (CESM) versus breast magnetic resonance imaging (MRI): A retrospective comparison in 66 breast lesions. AB - OBJECTIVE: The purpose of this study was to retrospectively compare the diagnostic performance of contrast-enhanced spectral mammography (CESM) with that of breast magnetic resonance imaging (BMRI) in breast cancer detection using parameters, including sensitivity, positive predictive value (PPV), lesion size, morphology, lesion and background enhancement, and examination time. MATERIALS AND METHODS: A total of 48 women (mean age, 56years+/-10.6 [SD]) with breast lesions detected between October 2012 and March 2014 were included. Both CESM and BMRI were performed for each patient within 30 days. The enhancement intensity of lesions and breast background parenchyma was subjectively assessed for both modalities and was quantified for comparison. Statistical significance was analyzed using paired t-test for mean size of index lesions in all malignant breasts (an index lesion defined as the largest lesion in each breast), and a mean score of enhancement intensity for index lesions and breast background. PPV, sensitivity, and accuracy were calculated for both CESM and BMRI. The average duration time of CESM and MRI examinations was also compared. RESULTS: A total of 66 lesions were identified, including 62 malignant and 4 benign lesions. Both CESM and BMRI demonstrated a sensitivity of 100% for detection of breast cancer. There was no statistically significant difference between the mean size of index lesions (P=0.108). The enhancement intensity of breast background was significantly lower for CESM than for BMRI (P<0.01). The mean score of enhancement intensity of index lesions on CESM was significantly less than that for BMRI (P<0.01). The smallest lesion that was detected by both modalities measured 4mm. CESM had a higher PPV than BMRI (P>0.05). The average examination time for CESM was significantly shorter than that of BMRI (P<0.01). CONCLUSION: CESM has similar sensitivity than BMRI in breast cancer detection, with higher PPV and less background enhancement. CESM is associate with significantly shorter exam time thus a more accessible alternative to BMRI, and has the potential to play an important tool in breast cancer detection and staging. PMID- 27687830 TI - Normal postoperative appearances of lung cancer. AB - The major lung resections are the pneumonectomies and lobectomies. The sublobar resections are segmentectomies and wedge resections. These are performed either through open surgery through a thoracotomy or by video-assisted mini-invasive surgery for lobectomies and sublobar resections. Understanding the procedures involved allows the normal postoperative appearances to be interpreted and these normal anatomical changes to be distinguished from potential postoperative complications. Surgery results in a more or less extensive physiological adaptation of the chest cavity depending on the lung volume, which has been resected. This adaptation evolves during the initial months postoperatively. Chest radiography and computed tomography can show narrowing of the intercostal spaces, a rise of the diaphragm and shift of the mediastinum on the side concerned following major resections. PMID- 27687831 TI - Correlation between apparent diffusion coefficient value on diffusion-weighted MR imaging and Gleason score in prostate cancer. AB - OBJECTIVES: To investigate whether diffusion-weighted imaging (DWI) apparent diffusion coefficient (ADC) correlates with prostate cancer aggressiveness and further to compare the diagnostic performance of ADC and normalized ADC (nADC: normalized to non-tumor tissue). PATIENTS AND METHODS: Thirty pre-treatment patients (mean age, 69years; range: 59-78years) with prostate cancer underwent magnetic resonance imaging (MRI) examination, including DWI with three b values: 50, 400, and 800s/mm2. Both ADC and nADC were correlated with the Gleason score obtained through transrectal ultrasound-guided biopsy. RESULTS: The tumor minimum ADC (ADCmin: the lowest ADC value within tumor) had an inverse correlation with the Gleason score (r=-0.43, P<0.05), and it was lower in patients with Gleason score 3+4 than in those with Gleason score 3+3 (0.54+/-0.11*103mm2/s vs. 0.64+/ 0.12*10-3mm2/s, P<0.05). Both the nADCmin and nADCmean correlated with the Gleason score (r=-0.52 and r=-0.55, P<0.01; respectively), and they were lower in patients with Gleason score 3+4 than those with Gleason score 3+3 (P<0.01; respectively). Receiver operating characteristic (ROC) analysis showed that the area under the ROC curve was 0.765, 0.818, or 0.833 for the ADCmin, nADCmin, or nADCmean; respectively, in differentiating between Gleason score 3+4 and 3+3 tumors. CONCLUSION: Tumor ADCmin, nADCmin, and nADCmean are useful markers to predict the aggressiveness of prostate cancer. PMID- 27687832 TI - A single enhanced phase is sufficient for the initial computed tomography evaluation of retroperitoneal tumors in children. AB - PURPOSE: The goal of this study was to evaluate the incremental value of unenhanced phase in the initial evaluation of retroperitoneal tumors in children by comparison with an enhanced phase alone using computed tomography (CT). MATERIALS AND METHODS: A total of 53 patients (26 girls, 27 boys) with a total of 53 tumors who had CT examination of the abdomen and pelvis for the initial assessment of retroperitoneal tumor were retrospectively included. All CT examinations were obtained with an unenhanced set of CT images and a set of CT images obtained after intravenous administration of iodinated contrast material. One junior and one senior radiologist independently evaluated the two sets in two separate reading sessions. CT images were analyzed for tumor calcifications, tumor location, vascular encasement, local invasion and tumor content. RESULTS: Calcifications were present in 24/53 tumors (45%). On the enhanced set, the senior radiologist was able to detect calcifications in 22/24 tumors (92%) and the junior radiologist in 20/24 tumors (83%), yielding sensitivities of 92% and 83%, and specificities of 96.5% and 100%, respectively. Inter-observer agreement was excellent (Kappa=0.89). Tumor location was correctly determined by the senior radiologist in 53/53 tumors (100%) and 37/53 tumors (70%) by the junior radiologist. Using the unenhanced set, the senior radiologist was able to assess vascular encasement in 26/53 tumors (49%) against 21/53 (39%) for the junior radiologist. For tumor content, agreement between the enhanced and combined unenhanced and enhanced CT was 77% for both radiologists. CONCLUSION: Enhanced CT performs as well as unenhanced CT for evidencing calcifications and is therefore sufficient for the initial assessment of retroperitoneal tumor in children.

AB - RNA interference (RNAi) is a useful reverse genetics tool for investigation of gene function as well as for practical applications in many fields including medicine and agriculture. RNAi works very well in coleopteran insects including the Colorado potato beetle (CPB), Leptinotarsa decemlineata. We used a cell line (Lepd-SL1) developed from CPB to identify genes that play key roles in RNAi. We screened 50 genes with potential functions in RNAi by exposing Lepd-SL1 cells to dsRNA targeting one of the potential RNAi pathway genes followed by incubation with dsRNA targeting inhibitor of apoptosis (IAP, silencing of this gene induces apoptosis). Out of 50 genes tested, silencing of 29 genes showed an effect on RNAi. Silencing of five genes (Argonaute-1, Argonaute-2a, Argonaute-2b, Aubergine and V-ATPase 16 kDa subunit 1, Vha16) blocked RNAi suggesting that these genes are essential for functioning of RNAi in Lepd-SL1 cells. Interestingly, Argonaute 1 and Aubergine which are known to function in miRNA and piRNA pathways respectively are also critical to siRNA pathway. Using 32P labeled dsRNA, we showed that these miRNA and piRNA Argonautes but not Argonaute-2 are required for processing of dsRNA to siRNA. Transfection of pIZT/V5 constructs containing these five genes into Sf9 cells (the cells where RNAi does not work well) showed that expression of all genes tested, except the Argonaute-2a, improved RNAi in these cells. Results from Vha16 gene silencing and bafilomycin-A1 treatment suggest that endosomal escape plays an important role in dsRNA-mediated RNAi in Lepd-SL1 cells. PMID- 27687846 TI - Gossypol toxicity and detoxification in Helicoverpa armigera and Heliothis virescens. AB - Gossypol is a polyphenolic secondary metabolite produced by cotton plants, which is toxic to many organisms. Gossypol's aldehyde groups are especially reactive, forming Schiff bases with amino acids of proteins and cross-linking them, inhibiting enzyme activities and contributing to toxicity. Very little is known about gossypol's mode of action and its detoxification in cotton-feeding insects that can tolerate certain concentrations of this compound. Here, we tested the toxicity of gossypol and a gossypol derivative lacking free aldehyde groups (SB gossypol) toward Helicoverpa armigera and Heliothis virescens, two important pests on cotton plants. Larval feeding studies with these two species on artificial diet supplemented with gossypol or SB-gossypol revealed no detectable toxicity of gossypol, when the aldehyde groups were absent. A cytochrome P450 enzyme, CYP6AE14, is upregulated in H. armigera feeding on gossypol, and has been claimed to directly detoxify gossypol. However, using in vitro assays with heterologously expressed CYP6AE14, no metabolites of gossypol were detected, and further studies suggest that gossypol is not a direct substrate of CYP6AE14. Furthermore, larvae feeding on many other plant toxins also upregulate CYP6AE14. Our data demonstrate that the aldehyde groups are critical for the toxicity of gossypol when ingested by H. armigera and H. virescens larvae, and suggest that CYP6AE14 is not directly involved in gossypol metabolism, but may play a role in the general stress response of H. armigera larvae toward plant toxins. PMID- 27687847 TI - Hospital Volume and Outcomes of Robot-Assisted Lobectomies. AB - BACKGROUND: The positive impact of hospital operative volume on outcomes following video-assisted thoracoscopic surgery has been established. The goal of this study was to determine whether or not this volume/outcome relationship translates to robot-assisted thoracoscopic surgery (RobATS) lobectomy. METHODS: Patients who underwent RobATS lobectomy were identified between 2008 and 2013 in the Healthcare Cost and Utilization Project National Inpatient Sample database. Hospital volume, as well as demographic, clinical, and health-care system-related factors were selected as potential predictors of outcomes. Outcome variables included length of stay (LOS), inpatient mortality, and complications. Hospitals were designated by quartiles according to annual case volume, with very low volume defined as the first quartile and high-volume defined as the fourth quartile. Regression analyses were used to identify independent predictors of the outcomes of interest. RESULTS: A total of 8,253 RobATS lobectomies were identified. Compared with very low-volume centers, patients at high-volume hospitals had a shorter mean LOS (5.8 vs 6.5 days; P = .001) and decreased mortality rate (0.5% vs 1.9%; P < .001) but more complications (28.1% vs 27.6%; P = .025). In multivariable analysis, high hospital volume was prognostic for decreased mortality (OR, 0.134; P< .001) and shorter LOS (0.2 days; SE, 0.05; P<.001). Hospital volume was not prognostic for any complications, including pulmonary, cardiovascular, intraoperative, or infectious complications. CONCLUSIONS: Undergoing lobectomy at high-volume RobATS centers confers favorable mortality and LOS outcomes compared with very low-volume centers. In this relatively early phase of adoption of RobATS, the long-term clinical impact of differences in LOS as well as the lack of clinical impact on the incidence of complications remain to be determined more definitively. However, the beneficial effect of volume on mortality suggests a need for the careful adoption of this promising technology. PMID- 27687849 TI - Heroes of peer review: Hyongbum (Henry) Kim.

PMID- 27687848 TI - Association of Sarcoidosis With Increased Risk of VTE: A Population-Based Study, 1976 to 2013. AB - OBJECTIVE: The goal of this study was to investigate the risk of VTE among patients with sarcoidosis. METHODS: A cohort of 345 incident cases of sarcoidosis and 345 sex- and age-matched comparator subjects in Olmsted County, Minnesota, from 1976 to 2013 were identified from the comprehensive medical record linkage system. Medical records were reviewed for DVT and pulmonary embolism (PE). The cumulative incidence was estimated, adjusted for the competing risk of death. Cox proportional hazards models were used to compare the rate of development of these events between patients with sarcoidosis and the nonsarcoidosis comparison cohort. RESULTS: The prevalence of VTE, DVT, and PE prior to the index date was not significantly different between case and comparator subjects. The risk of incident VTE adjusted for age, sex, and calendar year was significantly higher among patients with sarcoidosis (hazard ratio [HR], 3.04 [95% CI, 1.47-6.29]). Significantly elevated risk was observed in both subtypes of VTE, with an HR of 3.14 (95% CI, 1.32-7.48) for DVT and an HR of 4.29 (95% CI, 1.21-15.23) for PE. A sensitivity analysis including only VTE events that occurred at least 6 months after the index date adjusted for age, sex, and calendar year revealed somewhat lower HRs: VTE, 2.73 (95% CI, 1.30-5.72); DVT, 3.00 (95% CI, 1.25-7.20); and PE, 3.58 (95% CI, 0.98-13.03). CONCLUSIONS: An increased risk of VTE among patients with sarcoidosis was observed in this population-based cohort.

MATERIALS AND METHODS: After 'in vitro' demonstration of H. pylori DNA detection from pure and stool-mixed bacteria, 52 consecutive patients at the first diagnosis of infection were investigated. DNA was extracted from biopsy tissue and stool samples (THD(r) Fecal Test, Italy). RT-PCR was performed to detect 23S rRNA encoding bacterial subunit gene and search A2143G, A2142C, A2142G point mutations for clarithromycin resistance assessment. RESULTS: RT-PCR showed H. pylori positive DNA in all infected patients with full concordance between tissue and stool detection (100%). We found A2143G mutation in 10 (19.2%), A2142G in 4 (7.7%) and A2142C in 5 (9.6%) patients; there was a full agreement between biopsy and fecal samples. A2143G was found in all the four A2142G positive cases and in three out of the five A2142C positive strains. Overall clarithromycin resistance rate in our series was 23%. CONCLUSIONS: Despite the need of confirmation on large sample, stool RT-PCR analysis could represent a feasible tool to detect H. pylori DNA sequences and antibiotic resistance point mutations. As compared to tissue molecular analysis, this technique is noninvasive, with potential advantages such as improvement of patient compliance, reduction of diagnostic procedure time/cost and improvement of therapeutic outcome. PMID- 27687852 TI - Laparoscopic Removal of a Retroperitoneal Hysteroscopic Microinsert Using Fluoroscopy. AB - Perforation during placement of hysteroscopic microinserts for permanent sterilization occurs in approximately .9% to 2.6% of women undergoing the procedure. Most of the time perforation results in intraperitoneal placement of the hysteroscopic microinsert requiring laparoscopy or laparotomy for removal of the device. Herein we present a case of hysteroscopic microinsert perforation with subsequent retroperitoneal identification of the device. This is the first such case to our knowledge of retroperitoneal identification and retrieval of a perforated device that required real-time fluoroscopy during laparoscopy. PMID- 27687851 TI - A Randomized Controlled Multicenter US Food and Drug Administration Trial of the Safety and Efficacy of the Minerva Endometrial Ablation System: One-Year Follow Up Results. AB - STUDY OBJECTIVE: To assess the safety and effectiveness of the Minerva Endometrial Ablation System for the treatment of heavy menstrual bleeding in premenopausal women. DESIGN: Multicenter, randomized, controlled, international study (Canadian Task Force classification I). SETTING: Thirteen academic and private medical centers. PATIENTS: Premenopausal women (n = 153) suffering from heavy menstrual bleeding (PALM-COEIN: E, O). INTERVENTION: Patients were treated using the Minerva Endometrial Ablation System or rollerball ablation. MEASUREMENTS AND MAIN RESULTS: At 1-year post-treatment, study success (alkaline hematin <=80 mL) was observed in 93.1% of Minerva subjects and 80.4% of rollerball subjects with amenorrhea reported by 71.6% and 49% of subjects, respectively. The mean procedure times were 3.1 minutes for Minerva and 17.2 minutes for rollerball. There were no intraoperative adverse events and/or complications reported. CONCLUSION: The results of this multicenter randomized controlled trial demonstrate that at the 12-month follow-up, the Minerva procedure produces statistically significantly higher rates of success, amenorrhea, and patient satisfaction as well as a shorter procedure time when compared with the historic criterion standard of rollerball ablation. Safety results were excellent and similar for both procedures. PMID- 27687853 TI - Conservative Management of Cesarean Scar Pregnancy Following Diagnosis via Magnetic Resonance Imaging. PMID- 27687854 TI - Integrating informal providers into a people-centered health systems approach: qualitative evidence from local health systems in rural Nigeria. AB - BACKGROUND: The presence of a large informal healthcare sector in many low- and middle-income countries poses both challenges and opportunities for achieving a people-centered health system. However, few studies have considered how informal providers may fit into a people-centered health systems approach. We examine the self-described roles and motivations of informal medicine vendors and public healthcare workers in rural Nigeria, as well as interactions between them, with the aim of identifying how local health systems may be reoriented for improved service delivery through a people-centered approach. METHODS: We analyzed data from in-depth interviews with 70 medicine vendors and 21 staff of public health facilities in 30 villages across Kogi, Kwara and Enugu states in Nigeria. Interview guides covered the respondent's or her facility's role in providing health services to the local community, motivation to work in her respective profession, and relationships and interactions with other frontline healthcare providers. Data were analyzed in Atlas.ti using an open coding approach. RESULTS: Both medicine vendors and staff of public health facilities viewed themselves as fulfilling an essential primary healthcare function in their villages, and described their main motivation as the desire to help their communities. Medicine vendors were acknowledged by both groups to play an important role in providing care close to underserved rural communities, but within a limited scope of practice. Vendors described referring cases beyond their self-defined capacity to the local public facility. Health facility staff also sent clients to vendors to purchase drugs that were out of stock. However, referrals were informal and unspecific in nature, and the degree to which relationships between vendors and health facility staff were collaborative was highly context-dependent despite their recognized interdependencies in health services provision. CONCLUSIONS: Policies aimed at fostering people-centered health systems should consider the role of informal providers in the delivery of integrated care. In the context of our rural study sites in Nigeria, supporting stronger and more consistent linkages between medicine vendors and public health facilities is a key step towards improving health service delivery. PMID- 27687856 TI - The Effect of Cushion Properties on Skin Temperature and Humidity at the Body Support Interface. AB - PURPOSE: To explore the effects of various cushions on skin temperature and moisture at the body-seat interface during a 2-h period of continuous sitting. METHOD: Seventy-eight participants were randomly assigned to sit on one of the three types of wheelchair cushion for unrelieved sitting over 2 h. Skin temperature and relative humidity (RH) were measured under the subjects' ischial tuberosities and thighs bilaterally with digital temperature and humidity sensors. Data were collected before sitting and at 15-min intervals thereafter. RESULTS: Participants sitting on foam-fluid hybrid cushions showed significantly lower skin temperatures than those sitting on air-filled and foam cushions (p < 0.05), but RH did not differ significantly among the cushions (p = 0.97). The three cushions produced a similar increasing trend in RH over time and RH reached a plateau during the 2-h sitting period. CONCLUSION: In order to select the appropriate wheelchair cushion, the microclimate (heat and moisture control) between the body-seat interface should be considered as well as pressure distribution. In comparison with foam-fluid hybrid cushions, the air-filled rubber and foam cushions tended to increase skin temperature by several degrees after prolonged sitting. However, cushion materials did not have significant differences in moisture accumulations. PMID- 27687855 TI - Adolescent Female Text Messaging Preferences to Prevent Pregnancy After an Emergency Department Visit: A Qualitative Analysis. AB - BACKGROUND: Over 15 million adolescents use the emergency department (ED) each year in the United States. Adolescent females who use the ED for medical care have been found to be at high risk for unintended pregnancy. Given that adolescents represent the largest users of text messaging and are receptive to receiving text messages related to their sexual health, the ED visit represents an opportunity for intervention. OBJECTIVE: The aim of this qualitative study was to explore interest in and preferences for the content, frequency, and timing of an ED-based text message intervention to prevent pregnancy for adolescent females. METHODS: We conducted semistructured, open-ended interviews in one urban ED in the United States with adolescent females aged 14-19 years. Eligible subjects were adolescents who were sexually active in the past 3 months, presented to the ED for a reproductive health complaint, owned a mobile phone, and did not use effective contraception. Using an interview guide, enrollment continued until saturation of key themes. The investigators designed sample text messages using the Health Beliefs Model and participants viewed these on a mobile phone. The team recorded, transcribed, and coded interviews based on thematic analysis using the qualitative analysis software NVivo and Excel. RESULTS: Participants (n=14) were predominantly Hispanic (13/14; 93%), insured (13/14; 93%), ED users in the past year (12/14; 86%), and frequent text users (10/14; 71% had sent or received >30 texts per day). All were interested in receiving text messages from the ED about pregnancy prevention, favoring messages that were "brief," "professional," and "nonaccusatory." Respondents favored texts with links to websites, repeated information regarding places to receive "confidential" care, and focused information on contraception options and misconceptions. Preferences for text message frequency varied from daily to monthly, with random hours of delivery to maintain "surprise." No participant feared that text messages would violate her privacy. CONCLUSIONS: Adolescent female patients at high pregnancy risk are interested in ED-based pregnancy prevention provided by texting. Understanding preferences for the content, frequency, and timing of messages can guide in designing future interventions in the ED. PMID- 27687857 TI - Triterpenoids from Abies faxoniana and their cytotoxic activities. AB - Two previously unreported triterpenoids (1 and 2) and four known compounds were isolated from Abies faxoniana. Compound 1 has a alpha,beta-unsaturated-gamma lactone ring conjugated with the C-22/23 olefin in the C-17 side chain. The structures of the new compounds were established on the basis of spectroscopic data analysis. These compounds were tested for their cytotoxicities against six human tumour cell lines. Compound 1 showed cytotoxic activities against MCF-7 and A549 cells with IC50 values of 7.5 and 8.7 MUM, respectively. PMID- 27687859 TI - A review of emerging IL-17 inhibitors in the treatment of psoriasis focusing on preclinical through phase II studies. AB - INTRODUCTION: Interleukin-17 has recently been identified as a key player in the pathogenesis of psoriasis. As such, several drugs targeting IL-17 are in various stages of clinical development. Areas covered: In this review, the authors describe several emerging therapies and drug candidates targeting IL-17. The authors detail many biologic injectable drug candidates as well as numerous potential oral and topical small molecule drug candidates. Expert opinion: Approval of IL-17 inhibitors has significantly improved the treatment options for psoriasis patients. Secukinumab and ixekizumab are approved in both Europe and the USA, and brodalumab is likely facing approval by the end of 2016. Numerous additional biologic and small molecule drug candidates are in the pipeline, and once deemed safe and effective will likely offer significant benefit to our psoriasis population. PMID- 27687858 TI - The lung mycobiome in the next-generation sequencing era. AB - The fungi that reside in the human lungs represent an understudied, but medically relevant comm-unity. From the few studies published on the lung mycobiome, we find that there are fungi in both the healthy and diseased respiratory tract, that these fungi vary widely between individuals, and that there is a trend toward lower fungal diversity among individuals with disease. This review discusses the few studies of the lung mycobiome and details the challenges that accompany lung mycobiome studies. These challenges include sample collection and processing, sequence amplification and processing, and a history of multiple names for species. Some challenges may never be solved, but others can be solved with more data and additional studies of the lung mycobiome.

PMID- 27687860 TI - The role of Silodosin as a new medical expulsive therapy for ureteral stones: a meta-analysis. AB - To evaluate the efficacy of Silodosin as a medical expulsive therapy of ureteral stones, we searched PubMed, EMBASE, the Cochrane Library, and CBM up to June 2015. All randomized controlled trials (RCTs) were identified in which patients were randomized to receive Silodosin versus placebo or other therapies for ureteral stones. Outcome measures assessed were overall stone expulsion rate (primary) and expulsion time, analgesics times, and the incidence of additional treatment and regarding treatment complications (secondary). Two authors independently assessed study quality and extracted data. All data were analyzed using RevMan 5.3. Seven RCTs with a total of 1035 patients met the inclusion criteria. The pooled meta-analysis showed a significant improvement in stone clearance with Silodosin (Silodosin versus placebo, OR =1.69, 95% CI [1.19-2.40], p = 0.003; Silodosin versus tamsulosin, OR =2.82, 95% CI [1.79-4.44], p < 0.00001). According to the size and location of ureteral stone, the pooling effects of Silodosin were analyzed, with a meaningful expulsion rate in distal ureteral stone when the size was 5-10 mm. In addition, a shorter expulsion time, fewer analgesics times, and additional treatments were observed. The common side effect was retrograde ejaculation. In summary, Silodosin appears to be more effective than either placebo or tamsulosin. Within the limits of available data, high-quality multicenter RCTs are needed to thoroughly evaluate the outcome in the future. PMID- 27687862 TI - Type-specific detection of herpes simplex virus type 1 and type 2 using the cobas(r) HSV 1 and 2 test on the cobas(r) 4800 platform. AB - INTRODUCTION: HSV-1 and HSV-2 are among the most common causes of sexually transmitted infections (stis) globally. these infections are strongly associated with increased risk of hiv acquisition and rare, but devastating, neonatal disease. available treatment options can reduce HSV transmission and improve quality of life. accurate diagnosis early in disease can improve patient management. Areas covered: This paper describes the clinical manifestations of HSV infection often used for clinical diagnostic purposes. The paper then describes the evolution of laboratory diagnostic assays. Serology, culture and molecular diagnostics are described since all are currently in use. The features and performance characteristics of the cobas 4800 HSV1 and HSV2 Test (cobas HSV) on the cobas 4800(r) system (cobas 4800) are described in detail. Expert commentary: Diagnosis of HSV has historically been unreliable or technically difficult, but the availability of molecular assays such as the cobas HSV test for detection and typing of herpes can improve our ability to correctly manage this disease. Utilization of tools such as the cobas HSV assay may help shorten the time to accurate diagnosis and treatment thus potentially reducing the risk of transmission and the global burden of HSV. PMID- 27687863 TI - Simple and rapid direct cloning and heterologous expression of natural product biosynthetic gene cluster in Bacillus subtilis via Red/ET recombineering. AB - Heterologous expression of biosynthetic pathways is an important way to research and discover microbial natural products. Bacillus subtilis is a suitable host for the heterologous production of natural products from bacilli and related Firmicutes. Existing technologies for heterologous expression of large biosynthetic gene clusters in B. subtilis are complicated. Herein, we present a simple and rapid strategy for direct cloning based heterologous expression of biosynthetic pathways in B. subtilis via Red/ET recombineering, using a 5.2 kb specific direct cloning vector carrying homologous sequences to the amyE gene in B. subtilis and CcdB counterselection marker. Using a two-step procedure, two large biosynthetic pathways for edeine (48.3 kb) and bacillomycin (37.2 kb) from Brevibacillus brevis X23 and B. amyloliquefaciens FZB42, respectively, were directly cloned and subsequently integrated into the chromosome of B. subtilis within one week. The gene cluster for bacillomycin was successfully expressed in the heterologous host, although edeine production was not detectable. Compared with similar technologies, this method offers a simpler and more feasible system for the discovery of natural products from bacilli and related genera. PMID- 27687864 TI - The domesticated brain: genetics of brain mass and brain structure in an avian species. AB - As brain size usually increases with body size it has been assumed that the two are tightly constrained and evolutionary studies have therefore often been based on relative brain size (i.e. brain size proportional to body size) rather than absolute brain size. The process of domestication offers an excellent opportunity to disentangle the linkage between body and brain mass due to the extreme selection for increased body mass that has occurred. By breeding an intercross between domestic chicken and their wild progenitor, we address this relationship by simultaneously mapping the genes that control inter-population variation in brain mass and body mass. Loci controlling variation in brain mass and body mass have separate genetic architectures and are therefore not directly constrained. Genetic mapping of brain regions indicates that domestication has led to a larger body mass and to a lesser extent a larger absolute brain mass in chickens, mainly due to enlargement of the cerebellum. Domestication has traditionally been linked to brain mass regression, based on measurements of relative brain mass, which confounds the large body mass augmentation due to domestication. Our results refute this concept in the chicken. PMID- 27687865 TI - Arsenic prepared by Chinese alchemist-pharmacists. PMID- 27687867 TI - Nonlinear optical observation of coherent acoustic Dirac plasmons in thin-film topological insulators. AB - Low-energy collective electronic excitations exhibiting sound-like linear dispersion have been intensively studied both experimentally and theoretically for a long time. However, coherent acoustic plasmon modes appearing in time domain measurements are rarely observed due to Landau damping by the single particle continua. Here we report on the observation of coherent acoustic Dirac plasmon (CADP) modes excited in indirectly (electrostatically) opposite-surface coupled films of the topological insulator Bi2Se3. Using transient second harmonic generation, a technique capable of independently monitoring the in-plane and out-of-plane electron dynamics in the films, the GHz-range oscillations were observed without corresponding oscillations in the transient reflectivity. These oscillations were assigned to the transverse magnetic and transverse electric guided CADP modes induced by the evanescent guided Lamb acoustic waves and remained Landau undamped due to fermion tunnelling between the opposite-surface Dirac states. PMID- 27687866 TI - Genetic controls of DNA damage avoidance in response to acetaldehyde in fission yeast. AB - Acetaldehyde, a primary metabolite of alcohol, forms DNA adducts and disrupts the DNA replication process, causing genomic instability, a hallmark of cancer. Indeed, chronic alcohol consumption accounts for approximately 3.6% of all cancers worldwide. However, how the adducts are prevented and repaired after acetaldehyde exposure is not well understood. In this report, we used the fission yeast Schizosaccharomyces pombe as a model organism to comprehensively understand the genetic controls of DNA damage avoidance in response to acetaldehyde. We demonstrate that Atd1 functions as a major acetaldehyde detoxification enzyme that prevents accumulation of Rad52-DNA repair foci, while Atd2 and Atd3 have minor roles in acetaldehyde detoxification. We found that acetaldehyde causes DNA damage at the replication fork and activates the cell cycle checkpoint to coordinate cell cycle arrest with DNA repair. Our investigation suggests that acetaldehyde-mediated DNA adducts include interstrand-crosslinks and DNA-protein crosslinks. We also demonstrate that acetaldehyde activates multiple DNA repair pathways. Nucleotide excision repair and homologous recombination, which are both epistatically linked to the Fanconi anemia pathway, have major roles in acetaldehyde tolerance, while base excision repair and translesion synthesis also contribute to the prevention of acetaldehyde-dependent genomic instability. We also show the involvement of Wss1-related metalloproteases, Wss1 and Wss2, in acetaldehyde tolerance. These results indicate that acetaldehyde causes cellular stresses that require cells to coordinate multiple cellular processes in order to prevent genomic instability. Considering that acetaldehyde is a human carcinogen, our genetic studies serve as a guiding investigation into the mechanisms of acetaldehyde-dependent genomic instability and carcinogenesis. PMID- 27687868 TI - SMC4, which is essentially involved in lung development, is associated with lung adenocarcinoma progression. AB - Structural maintenance of chromosome 4 (SMC4) is a core subunit of condensin complexes that mainly contributes to chromosome condensation and segregation. Our previous study demonstrated that the gene expression profile during lung development is of great values for the study of lung cancer. In this study, we identified SMC4 through co-expression network analysis and clique percolation clustering using genes that constant changes during four stages of lung development. Gene ontology and KEGG pathway enrichment analysis demonstrated that SMC4 is closely related to cell cycle, cell adhesion, and RNA processing in lung development and carcinogenesis. Moreover, SMC4 is overexpressed in lung adenocarcinoma tissues and acts as an independent prognostic factor. SMC4 knockdown significantly inhibits the proliferation and invasion of A549 cells. Furthermore, we found that SMC4 interacts with DDX46 (DEAD-box helicase 46). In conclusion, the pivotal role of SMC4 in lung development and carcinogenesis suggests that genes with a similar expression pattern to SMC4 in lung development may also contribute to lung cancer progression. The identification of genes that are essentially involved in development through a comparative study between development and cancer may be a practical strategy for discovering potential biomarkers and illuminating the mechanisms of carcinogenesis. PMID- 27687869 TI - Allogeneic hematopoietic stem cell transplant in adult patients with myelodysplastic syndrome/myeloproliferative neoplasm (MDS/MPN) overlap syndromes. AB - MDS/MPN (myelodysplastic syndrome/myeloproliferative neoplasm) overlap syndromes are myeloid malignancies for which allogeneic hematopoietic stem cell transplant (allo-HSCT) is potentially curative. We describe transplant outcomes of 43 patients - 35 with chronic myelomonocytic leukemia, CMML (of which 17 had blast transformation, BT) and eight with MDS/MPN-unclassifiable (MDS/MPN,U). At median follow-up of 21 months, overall survival (OS), cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) were 55%, 29%, and 25% respectively in CMML without BT and 47%, 40%, and 34% respectively in CMML with BT. Higher HSCT comorbidity index (HSCT-CI >3 versus <=3; p = 0.015) and splenomegaly (p = 0.006) predicted worse OS in CMML without BT. In CMML with BT, engraftment failure (p = 0.006) and higher HSCT-CI (p = 0.03) were associated with inferior OS, while HSCT within 1-year of diagnosis was associated with improved OS (p = 0.045). In MDS/MPN,U, at median follow-up of 15 months, OS, CIR, and NRM were 62%, 30%, and 14%, respectively. PMID- 27687870 TI - Neuro-visual rehabilitation. AB - Despite the fact that almost one-third of patients suffer from visual deficits following brain damage; neuro-visual rehabilitation to compensate for visual field deficits is relatively neglected in the clinical setting. This is in contrast to physio and speech therapies, which are the bread and butter of rehabilitative programs. Likewise, programs that address coping with dementia usually concentrate on language, memory and cognitive skills, but often fail to address the deficits experienced by the subset of patients suffering from progressive cortico-visual dysfunction. Herein, we will review the different approaches to neuro-visual rehabilitation, mainly concentrating on restorative and compensatory treatments. While the first claims to restore vision in the blind visual field, the latter attempts to improve the use of the remaining intact field. These approaches differ in their premise regarding the ability of the adult human brain to adapt following damage, reflecting different attitudes toward the presumed treatment target organ. While restorative therapies claim to reactivate inactive neurons within or around the damaged cortices, compensatory approaches aim to improve voluntary eye movements to compensate the visual loss. We will also briefly discuss the use of optical devices for bypassing the visual deficit as well as the use of the blind-sight phenomena to convert non-conscious visual abilities in the blind visual field into awareness. The various therapeutic approaches will be discussed in the context of patients suffering from hemianopsia and in patients suffering from posterior cortical atrophy. We will argue that of all, the compensatory strategies have shown the most promising results. PMID- 27687871 TI - Extremely Acidic Soils are Dominated by Species-Poor and Highly Specific Fungal Communities. AB - Highly acidic soils (pH < 3) represent an environment which might potentially offer new biotechnologically interesting fungi. Nevertheless, only little data on fungal communities in highly acidic habitats are available. Here, we focused on the diversity of cultivable filamentous microfungi in highly acidic soils (pH < 3) in the Czech Republic. Altogether, 16 soil samples were collected from four sampling sites and were processed by various approaches. In total, 54 fungal taxa were isolated and identified using classical as well as molecular markers. All dominant species were found both as living mycelia and as resistant stages. Numerous recently described or unknown taxa were isolated. The core of the fungal assemblage under study consisted of phylogenetically unrelated and often globally distributed fungi exclusively inhabiting highly acidic habitats like Acidiella bohemica, Acidomyces acidophilus, and unidentified helotialean fungus, as well as taxa known from less acidic and often extreme environments like Acidea extrema, Penicillium simplicissimum s.l., and Penicillium spinulosum. The large number of identified specialized species indicates that highly acidic environments provide suitable conditions for the evolution of specialist species. The occurrence of ubiquitous fungi in highly acidic substrates points to the principal role of competition in the colonization of such environments. The detected taxa did not require low pH to survive, because they can grow in a broad range of pH. PMID- 27687872 TI - A Metabarcoding Survey on the Fungal Microbiota Associated to the Olive Fruit Fly. AB - The occurrence of interaction between insects and fungi is interesting from an ecological point of view, particularly when these interactions involve insect pests and plant pathogens within an agroecosystem. In this study, we aimed to perform an accurate analysis on the fungal microbiota associated to Bactrocera oleae (Rossi) through a metabarcoding approach based on 454 pyrosequencing. From this analysis, we retrieved 43,549 reads that clustered into 128 operational taxonomic units (OTUs), of which 29 resulted in the "core" associate fungi of B. oleae. This fungal community was mainly represented by sooty mould fungi, such as Cladosporium spp., Alternaria spp. and Aureobasidium spp., by plant pathogens like Colletotrichum spp. and Pseudocercospora spp., along with several other less abundant taxa whose ecology is unclear in most of the cases. Our findings lead to new insights into the microbial ecology of this specific ecological niche, enabling the understanding of a complex network of interactions within the olive agroecosystem.

PMID- 27687874 TI - Response to the Letter to the Editor: "Mitochondria isolated from the striatum of the brain exhibit a higher degree of oxidative phosphorylation coupling, which shows that they are not subject to energetic dysfunction upon acute paraquat administration". PMID- 27687875 TI - Intention and Moral Enhancement. AB - Recently philosophers have proposed a wide variety of interventions referred to as 'moral enhancements'. Some of these interventions are concerned with helping individuals make more informed decisions; others, however, are designed to compel people to act as the intervener sees fit. Somewhere between these two extremes lie interventions designed to direct an agent's attention either towards morally relevant issues - hat-hanging - or away from temptations to do wrong - hat hiding. I argue that these interventions fail to constitute genuine moral enhancement because, although they may result in more desirable outcomes - more altruism, more law-following, and/or less self-destructive behavior, they ignore a person's intentions, and often what makes an action right or wrong is the intent behind it. PMID- 27687876 TI - Insight into the Tribological Behavior of Liposomes in Artificial Joints. AB - Liposomes are widely used in drug delivery and gene therapy, and their new role as boundary lubricant in natural/artificial joints has been found in recent years. In this study, the tribological properties of liposomes on titanium alloy (Ti6Al4 V)/UHMWPE interface were studied by a ball-on-disc tribometer. The efficient reduction of friction coefficient and wear on both surfaces under various velocities and loads is found. A multilayer structure of physically adsorbed liposomes on Ti6Al4 V surface was also observed by atomic force microscope (AFM). Except for the hydration mechanism by phosphatidylcholine (PC) groups, the well-performed tribological properties by liposomes is also attributed to the existence of adsorbed liposome layers on both surfaces, which could reduce asperities contact and show great bearing capacity. This work enriches the research on liposomes for lubrication improvement on artificial surface and shows their value in clinical application. PMID- 27687877 TI - Tuning graphitic oxide for initiator- and metal-free aerobic epoxidation of linear alkenes. AB - Graphitic oxide has potential as a carbocatalyst for a wide range of reactions. Interest in this material has risen enormously due to it being a precursor to graphene via the chemical oxidation of graphite. Despite some studies suggesting that the chosen method of graphite oxidation can influence the physical properties of the graphitic oxide, the preparation method and extent of oxidation remain unresolved for catalytic applications. Here we show that tuning the graphitic oxide surface can be achieved by varying the amount and type of oxidant. The resulting materials differ in level of oxidation, surface oxygen content and functionality. Most importantly, we show that these graphitic oxide materials are active as unique carbocatalysts for low-temperature aerobic epoxidation of linear alkenes in the absence of initiator or metal. An optimum level of oxidation is necessary and materials produced via conventional permanganate-based methods are far from optimal. PMID- 27687878 TI - Genetic homogenization of the nuclear ITS loci across two morphologically distinct gentians in their overlapping distributions in the Qinghai-Tibet Plateau. AB - Interspecific hybridization and introgression can lead to partial genetic homogenization at certain neutral loci between morphologically distinct species and may obscure the species delimitation using nuclear genes. In this study, we investigated this phenomenon through population genetic survey of two alpine plants (Gentiana siphonantha and G. straminea) in the Qinghai-Tibet Plateau, where the distributions of two species are partly overlapped. We identified two clusters of chloroplast DNA haplotypes which correspond to the two species, and three clusters of ITS ribotypes. In addition to clusters specific to each species, the third ITS cluster, which was most likely derived from hybridization between the other two clusters and subsequent recombination and concerted evolution, was widely shared by two species in their adjacent areas. In contrast to the morphological distinctiveness of the two species, interspecific gene flow possibly led to genetic homogenization at their ITS loci. The new ITS lineage recovered for species in adjacent areas is distinctly different from original lineages found in allopatric areas. These findings may have general implications for our understanding of cryptic changes at some genetic loci caused by interspecific gene flow in the history, and they indicate that species delimitation should be based on a combination of both nuclear and chloroplast DNA sequence variations. PMID- 27687879 TI - Treatment with Hizentra in patients with primary and secondary immunodeficiencies: a real-life, non-interventional trial. AB - BACKGROUND: Although Hizentra is indicated for immunoglobulin replacement therapy in patients with primary and secondary immunodeficiencies, phase III trials have focused on patients with primary immunodeficiencies. In this 9-month, real-life, prospective, non-interventional, longitudinal, multicenter study of patients with primary and secondary immunodeficiencies in France, treatment modalities (primary endpoint), efficacy, safety, tolerability, quality of life, and treatment satisfaction were evaluated using descriptive statistics. RESULTS: Starting in January 2012, 117 patients were enrolled (99 adults, 18 children). Secondary immunodeficiencies were present in 48.7 % of patients. At follow-up, injections were administered every 7 days in 92.2 % of patients. Nine patients (7.8 %) were taking Hizentra every 10-14 days. The median dose of Hizentra administered was 0.1 g/kg/injection. Fifty-six patients were administered doses <0.1 g/kg/injection and 13 patients were administered doses >0.2 g/kg/injection. Mean trough IgG titers were 9.0 +/- 3.3 g/L (median 8.3 g/L). The mean yearly rate of infection was 1.2 +/- 1.9. Mean scores on the Short Form-36 physical and mental component summaries were 46.3 +/- 10.0 and 46.6 +/- 9.3, respectively. Scores on the Treatment Satisfaction Questionnaire for Medication ranged from 69.9 +/- 19.9 to 88.3 +/- 21.2 depending on the domain. Treatment with Hizentra was well tolerated. No single drug-related systemic reaction occurred in more than one patient and few local reactions were reported (n = 5). CONCLUSIONS: Under real life conditions and in a cohort that included patients with primary and secondary immunodeficiencies, treatment with Hizentra was effective and well tolerated and patients were generally satisfied with the treatment. PMID- 27687880 TI - The influence of migraine and female hormones on capsaicin-induced dermal blood flow. AB - Background Migraine is much more common in females than in males, and occurrence is associated with changes in female sex hormones. Calcitonin gene-related peptide (CGRP) plays a key role in migraine, and variations in female sex hormones may affect CGRP sensitivity and/or production. Objectives Investigate repeatability, gender differences, influence of the menstrual cycle and of migraine on CGRP-dependent changes in dermal blood flow (DBF). Methods CGRP dependent increases in DBF were assessed using laser Doppler perfusion imaging after topical application of 300 or 1000 ug capsaicin on the forearm of healthy subjects and migraine patients. Results In healthy males, DBF response did not vary over time and was comparable with DBF in male migraineurs. In healthy females, capsaicin-induced DBF responses to both doses of capsaicin were higher during menstruation compared to the late-secretory phase (p < 0.05); this menstrual cycle dependence was absent in female migraine patients. Compared to healthy subjects, female migraineurs displayed a higher DBF response both during menstruation and during the late-secretory phase (p < 0.05). Conclusions An increased capsaicin-induced, CGRP-mediated DBF response was observed during menstruation in healthy women, but in female migraine patients this increased response was not affected by the menstrual cycle.

AB - A new method for the screening of compounds with hypoglycemic effect from traditional Chinese medicines employing high-performance liquid chromatography and lipase-linked magnetic microspheres has been proposed. We hypothesized that the interaction of traditional Chinese medicine extracts with lipase-linked magnetic microspheres should decrease the concentration of compounds with hypoglycemic effect. Using this approach, the potential lipase inhibitors in Folium Mori extract were investigated. First, lipase was immobilized on magnetic microspheres by a chemical method. Then, by comparing the chromatograms of samples before and after the interaction with lipase-linked magnetic microspheres, seven compounds of Folium Mori extract were identified. It was found that protocatechuic acid, chlorogenic acid, protocatechualdehyde, rutin, isoquercitrin, astragalin, and dicaffeoylquinic acid B had evident combination with lipase-linked magnetic microspheres. Their hypoglycemic effects were verified in streptozocin-induced diabetic mice. In the present study, astragalin was verified to improve the glucose tolerance and lower the level of glucose in streptozocin-induced diabetic mice, which indicated that astragalin might be a new highly efficient lipase inhibitor. Based on these significant results, this method could be a convenient approach to screen potential lipase inhibitors from traditional Chinese medicines. Meanwhile, it also could be expanded to screen other active compounds in traditional Chinese medicines.

AB - BACKGROUND: Adipokines are biologically active, low-molecular weight peptides, which play a major role in metabolic homeostasis in humans. Leptin has gained increasing attention in pediatrics as a biomarker for various metabolic pathologies. Yet, its usefulness is hampered by the relative lack of reference values from pediatric settings. Accordingly, this study aims to evaluate serum concentrations of leptin, soluble leptin receptor (sOB-R), and free leptin index (FLI) in healthy Danish schoolchildren aged 6-18 years and subsequently to establish reference intervals across sex and age groups. METHODS: A total of 1193 healthy, non-obese Danish schoolchildren (730 girls, 463 boys) aged 6-18 years (median 11.9) were examined by trained medical staff. Serum leptin and sOB-R concentrations in venous fasting blood samples were quantitated by immunoassay. Percentile curves of leptin, sOB-R, and free leptin index were calculated using the General Additive Model for Location Scale and Shape (GAMLSS). RESULTS: Significant age and sex-dependent differences in circulating leptin levels were found. In boys, the median leptin concentration for all ages combined was 3.35 MUg/L (95%-interval: 0.71-22.47) and in girls, it was 9.89 ng/L (95%-interval: 2.06-41.49). For SOB-R, no sex-specific difference was found, and the median sOB R concentration was 8.24 MUg/L (IQR: 3.58-23.74; range: < 1.56-744.15). CONCLUSION: We demonstrated an age-dependent correlation with both serum leptin concentration and free leptin index with a gradual and significant increase in girls throughout childhood and adolescence and a significantly higher leptin concentration and free leptin index bell-shaped peak in early adolescence in boys. PMID- 27687883 TI - Independent and incremental prognostic value of exercise stress echocardiography in low cardiovascular risk female patients with chest pain. AB - BACKGROUND: Exercise stress echocardiography (ESEcho) is sufficiently sensitive and has high enough specificity for the clinical detection of coronary artery disease (CAD) in women. However, there was little data about the ability of ESEcho to detect CAD and predict clinical outcomes in female patients with chest pain and low global cardiovascular (CV) risks. The purposes of this study were (1) to determine the diagnostic accuracy of ESEcho, (2) to evaluate the clinical outcomes of major cardiovascular outcome (MACE), and (3) to assess the incremental prognostic value of ESEcho for the prediction of MACE in Korean female patients with low CV risks. METHODS: Over a period of 15 years, 3396 patients (57+/-10 years) female patients with chest pain but no previous history of CAD undergoing ESEcho and exercise stress electrocardiography (ESECG) were assessed. RESULTS: During a median follow-up period of 4.8 years (2.8-6.2 years), there were 19 (0.61%) MACE. Positive results for ESEcho were seen in 134 patients (3.9%). The sensitivity and specificity of ESEcho were 66.7% and 84.8%, respectively. Positive ESEcho was an independent predictor of MACE (multivariate hazard ratio: 0.019, 95% CI: 0.004-0.081). ESEcho was incremental to clinical and ESECG parameters to predict the MACE in low CV risk women. CONCLUSIONS: ESEcho is effective for the diagnosis of CAD in Korean female patients with chest pain, a population characterized by low cardiovascular risk profiles. Positive ESEcho was an independent predictor of MACE, and negative results were associated with favorable clinical outcomes. ESEcho was incremental to clinical and ESECG parameters to predict the MACE in low CV risk women. PMID- 27687884 TI - Neuromuscular and inflammatory responses to handball small-sided games: the effects of physical contact. AB - The aim of this study was to investigate the influence of physical contact on neuromuscular impairments and inflammatory response during handball small-sided games. Using a counterbalanced design, 12 elite male junior handball players were divided into two groups: contact (C-SSG) and no-contact (NC-SSG), performing both contact and no-contact small-sided games, in reverse order on two training sessions separated by 5 days. The methodology and rules were identical for the two SSG regimens, with the only difference being the inclusion or prohibition of upper body use for physical contacts. Upper and lower body neuromuscular performances and blood concentrations of inflammatory cytokine IL-6 were assessed before and immediately after the games. During small-sided games, video analysis was used to establish the physical contact counts. Significant differences were found in most upper and lower limbs muscles kinetic variables and in the physical contact events (all P < 0.001) following the two training regimens. There was an increase in IL-6 after C-SSG and no changes following NC-SSG (P < 0.05 and P = 0.12, respectively). Moreover, a strong correlation was found between the number of physical contacts and IL-6 responses (r = 0.971, P < 0.001) in C-SSG. This study indicates that an inflammatory response and large upper and lower body neuromuscular impairments result from physical contact in elite handball players. These outcomes outline the specific physiological profile of C-SSG that, in turn, might be used by practitioners and coaches as a practical approach to strategically select exercises in athlete's overall training program.

AB - AIM: To provide insight into fetal nucleated red blood cell (nRBC) development using genome-wide DNA methylation (DNAm) profiling. MATERIALS & METHODS: The DNAm profile (Illumina 450K array) of cord blood (n = 7) derived nRBCs was compared with B cells, CD4 and CD8 T cells, natural killer cells, granulocytes, monocytes and placenta (n = 5). RESULTS: nRBCs and placenta had similarly low array-wide DNAm compared with white blood cells, but their patterns of hypomethylation differed at biologically relevant subsets of the array. High interindividual variability in nRBC DNAm was driven by a negative association between DNAm and nRBC count. CONCLUSION: nRBC hypomethylation is likely an epigenetic signature of erythropoiesis rather than of early development. Variability in nRBC DNAm may stem from differences in the cell population's maturity or hematopoietic source.

AB - INTRODUCTION: Research on plant root chemical ecology has benefited greatly from recent developments in analytical chemistry. Numerous reports document techniques for sampling root volatiles, although only a limited number describe in situ collection. OBJECTIVES: To demonstrate a new method for non-invasive in situ passive sampling using solid phase micro extraction (SPME), from the immediate vicinity of growing roots. METHODS: SPME fibres inserted into polyfluorotetrafluoroethylene (PTFE) sampling tubes located in situ which were either perforated, covered with stainless steel mesh or with microporous PTFE tubing, were used for non-invasive sub-surface sampling of root volatiles from glasshouse-grown broccoli. Sampling methods were compared with above surface headspace collection using Tenax TA. The roots were either mechanically damaged or infested with Delia radicum larvae. Principal component analysis (PCA) was used to investigate the effect of damage on the composition of volatiles released by broccoli roots. RESULTS: Analyses by gas chromatography-mass spectrometry (GC MS) with SPME and automated thermal desorption (ATD) confirmed that sulphur compounds, showing characteristic temporal emission patterns, were the principal volatiles released by roots following insect larval damage. Use of SPME with in situ perforated PTFE sampling tubes was the most robust method for out-of-lab sampling. CONCLUSION: This study describes a new method for non-invasive passive sampling of volatiles in situ from intact and insect damaged roots using SPME. The method is highly suitable for remote sampling and has potential for wide application in chemical ecology/root/soil research. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - We conducted a randomized, controlled trial to examine the effects of a salt reduction and efficacy-maintenance program on the improvement and maintenance of self-care and self-efficacy in reducing the salt intake of older people with high blood pressure. A total of 51 participants with hypertension/prehypertension in Indonesia were randomly assigned to a control group or one of two intervention groups: salt-reduction training or salt-reduction and efficacy-maintenance. The salt-reduction and efficacy-maintenance group received educational training and a maintenance meeting; the participants' knowledge, attitudes, self-care practices, and self-efficacy significantly improved after training and were maintained after the maintenance meeting. Participants in the salt-reduction training group showed significant effects for the same variables; however, their food salt concentrations rebounded after the maintenance meeting. No significant improvement was found in the control group. The salt-reduction and efficacy maintenance group participants reported positive effects of salt reduction and different practices based on who prepared their meals. The salt-reduction and efficacy-maintenance group program was effective in improving and maintaining knowledge, attitudes, and self-efficacy of salt-reduction practices and could be applied with community-dwelling older people with high blood pressure. PMID- 27687888 TI - Immunosuppressive effects of arsenic in broiler chicks exposed to Newcastle disease virus. AB - To assess the effects of prolonged exposure to arsenic (As, as arsenate) on host immune competence overall and resistance to Newcastle disease (ND) viral infection in particular, a study was carried out in broiler chicks. At 7 days of age, chicks were assigned to groups that would undergo varying vaccination, challenge, and/or As exposures; Group 1 was a control; Group 2 was to receive Newcastle disease virus (NDV) only; two groups (Groups 3, 4) were to be given As daily (50 mg/kg, by gavage) from Days 7-35 of the experiment. All groups underwent normal vaccination on Days 5, 23, and 32 against live NDV (B1 type, LaSota strain); two groups (Groups 2, 4) were challenged with field-isolated NDV at Day 24. At Days 14, 21, 28, and 35 of age, subsets of chicks in each group were evaluated. The results showed feed intake and weight gain were lower in As treated and NDV-challenged chicks. In As-treated chicks, absolute and relative spleen weights were significantly greater, whereas those of the thymus significantly lower, over the entire 35-day period. Effects on bursa weights (absolute, relative) were only significantly reduced through Day 21. Antibody titers against ND were significantly reduced (vs. control) over the whole 35 days in birds that received As alone, but only significantly depressed through the first 21 days in birds that received As + NDV; thereafter, titers were significantly greater (in parallel with effects in birds that received NDV alone). In contrast, antibody responses to T-dependent antigen (Sheep red blood cells [SRBC]) were significantly lower in As only- and As + NDV-treated chicks throughout the study period. Among birds exposed to As (alone or with NDV), in situ phagocytic activity was elevated and cutaneous sensitivity responses decreased during the period from Day 28 to Day 35. NDV alone had spurious effects on phagocytic activity but did cause significant reductions in cutaneous sensitivity responses. It was concluded that arsenic decreased immunity in broiler chicks, thereby making them prone to ND. PMID- 27687889 TI - CD99 as surface anchor for human islet endocrine cell purification. AB - Rat and human beta cell proteomes were quantified by liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS), searching for cell surface markers. In human beta cells, CD99 (cluster of differentiation 99) was ranked among the plasma membrane proteins that combine a high molar abundance with a relative degree of selectivity for the endocrine cells of the islets of Langerhans. Therefore, the applicability of CD99 as anchor for islet endocrine cell purification was investigated. The CD99 gene and protein expression were studied using microarray, LC-MS/MS, western blotting, flow cytometry and immunofluorescence, and a protocol was developed for magnetic bead-mediated beta cell enrichment from human pancreas digests using available anti-CD99 antibodies. In human, but not in rat, CD99 protein and mRNA were abundantly expressed by islet endocrine cells but undetectable in exocrine pancreas. The extracellular CD99 epitopes appeared to be trypsin-resistant, enabling the binding of anti-CD99 antibodies to an insulin+/TSQ+ cell subset and efficient coupling of magnetic beads for positive selection of CD99+ cells. A MACS-CD99 purification of human pancreas fractions with low endocrine purity consistently yielded a fourfold enrichment of insulin+/TSQ+ cells and formation of viable and functional endocrine aggregates after 24 h of culture. It is concluded that CD99 is a human beta cell surface marker that, by virtue of its high molar abundance and resistance to tryptic digestion, can be used as anchor for upscalable magnetic bead-mediated islet endocrine cell purification.

AB - OBJECTIVE: Computerized neuropsychological assessment of concussion has rapidly expanded and Immediate Post-Concussion and Cognitive Testing (ImPACT) is among the most commonly used measures in this domain. ImPACT was primarily developed for use with athletic populations but continues to expand beyond athletics to settings such as the workplace and schools where motivational dispositions may vary. The purpose of the present study was to conduct a systematic review of existing research investigating the prevalence of invalid baseline results and the effectiveness of ImPACT's embedded invalidity indicators in detecting suspect effort. METHOD: Preferred Reporting Items for Systematic Reviews and Meta Analyses guidelines were followed in order to systematically structure a search across four databases and analysis of studies that presented data related to the prevalence of invalid performance and/or the effectiveness of ImPACT's embedded invalidity indicators. RESULTS: A total of 17 studies included prevalence rates of invalid performances or examined the effectiveness of ImPACT's invalidity indicators. Of the 17 studies, 12 included prevalence rates of invalid baseline results; and across this group of studies (after removing an outlier), the weighted prevalence rate of invalid baseline results was 6%. Four of the 17 studies examined the effectiveness of ImPACT's embedded invalidity indicators. ImPACT's embedded invalidity indicators correctly identified suboptimal effort in approximately 80% of individuals instructed to perform poorly and avoid detection ('coached') or instructed to perform poorly ('naive'). CONCLUSIONS: These findings raise a number of issues pertaining to the use of ImPACT. Invalid performance incidence may increase with large group versus individual administration, use in nonclinical settings, and among those with Attention Deficit-Hyperactivity Disorder or learning disability. Additionally, the older desktop version of ImPACT appears to be associated with a higher rate of invalid performances than the online version. Although ImPACT's embedded invalidity indicators detect invalid performance at a rate of 6% on average, known group validity studies suggest that these measures miss invalid performance approximately 20% of the time when individuals purposefully underperform. PMID- 27687892 TI - The microsurgical training programme in Gothenburg, Sweden: early experiences. AB - OBJECTIVE: Microsurgical techniques are increasingly used in routine surgical practice as well as in biomedical research. The training opportunities at standardised training courses are limited, and no microsurgical training facility or programme existed in Scandinavia before 2013. METHODS: A microsurgery laboratory was set up and two different courses were started, aiming separately at biomedical researchers and surgeons. The course for biomedical researchers teaches basic microsurgical skills such as vessel isolation, cannulation, and arterial microvascular suture under magnification. The more advanced course for surgeons focuses on various techniques of microvascular and nerve anastomosis. Both courses use a combination of theory and practice, with emphasis on the practical part, the course for surgeons also includes clinically relevant information. RESULTS: Twelve 5-day courses using both non-living models and exercises on laboratory animals have been conducted and attended by 49 researchers and 44 surgeons. The organisation and the programme of the training courses as well as 'The 4E concept' behind the course (educational curriculum, equipment, ergonomy, and evaluation) are further detailed. CONCLUSIONS: We have successfully established the first training laboratory and series of microsurgical training courses in Scandinavia at two different levels. The experience from the first 12 courses shows the need for this type of structured training, and confirms that the microsurgical education curriculums needs to be adapted to participants' prerequisites and expectations, and various difficulty levels should be considered. PMID- 27687891 TI - Epigenetic Variability of CD4+CD25+ Tregs Contributes to the Pathogenesis of Autoimmune Diseases. AB - Autoimmune diseases are characterized by aberrant immune responses against healthy cells and tissues. However, the exact mechanisms underlying the development of these conditions remain unknown. CD4+CD25+ regulatory T cells (Tregs) are a subset of mature T cells which have an important role in maintaining immune homeostasis and preventing autoimmune diseases. Forkhead box p3 (Foxp3), a member of the fork head transcription factor family, is recognized as a marker of CD4+CD25+ Tregs. The decreased number and/or function of CD4+CD25+ Tregs in peripheral blood and related tissues has been demonstrated in systemic lupus erythematosus, systemic sclerosis, and other autoimmune diseases, which are at least partially regulated by epigenetic mechanisms. Epigenetics refers to the study of potentially heritable alterations in gene expression without underlying changes of the nucleotide sequence, mainly including DNA methylation, histone modification, and microRNAs (miRNAs). For example, DNA methylation status of CpG islands on the Foxp3 gene, which may be affected by normal aging and regulated by environmental factors, plays an important role in modulating the homeostasis of Foxp3 expression in Tregs. Foxp3 gene in Tregs also shows distinct acetylation and trimethylation levels of histone H3 and H4 when compared with effector T cells, leading to an open chromatin structure. MicroRNAs such as miR-155, miR 126, and miR-10a also exert an important influence on the differentiation, development, and immunological functions of Tregs. Aberrant epigenetic modifications affecting Foxp3 and other key genes in Tregs contribute to disease activity and tissue inflammation in autoimmune diseases, which holds great potential for providing novel targets for epigenetic therapies. Advances in research into the epigenetic regulation of CD4+CD25+ Tregs may also lead to the identification of new epigenetic biomarkers for diagnosis and prognosis. PMID- 27687895 TI - Consequences of removing cheap, super-strength beer and cider: a qualitative study of a UK local alcohol availability intervention. AB - OBJECTIVES: Increasingly, English local authorities have encouraged the implementation of an intervention called 'Reducing the Strength' (RtS) whereby off-licences voluntarily stop selling inexpensive 'super-strength' (>=6.5% alcohol by volume (ABV)) beers and ciders. We conceptualised RtS as an event within a complex system in order to identify pathways by which the intervention may lead to intended and unintended consequences. DESIGN: A qualitative study including a focus group and semistructured interviews. SETTING: An inner-London local authority characterised by a high degree of residential mobility, high levels of social inequality and a large homeless population. Intervention piloted in three areas known for street drinking with a high alcohol outlet density. PARTICIPANTS: Alcohol service professionals, homeless hostel employees, street based services managers and hostel dwelling homeless alcohol consumers (n=30). RESULTS: Participants describe a range of potential substitution behaviours to circumvent alcohol availability restrictions including consuming different drinks, finding alternative shops, using drugs or committing crimes to purchase more expensive drinks. Service providers suggested the intervention delivered in this local authority missed opportunities to encourage engagement between the council, alcohol services, homeless hostels and off-licence stores. Some participants believed small-scale interventions such as RtS may facilitate new forms of engagement between public and private sector interests and contribute to long-term cultural changes around drinking, although they may also entrench the view that 'problem drinking' only occurs in certain population groups. CONCLUSIONS: RtS may have limited individual-level health impacts if the target populations remain willing and able to consume alternative means of intoxication as a substitute for super-strength products. However, RtS may also lead to wider system changes not directly related to the consumption of super-strengths and their assumed harms. PMID- 27687894 TI - Isolation of a transcription factor DREB1A gene from Phaseolus vulgaris and computational insights into its characterization: protein modeling, docking and mutagenesis. AB - A transcription factor DREB1A (dehydration-responsive element-binding 1A) gene was amplified and sequenced from the common bean (Phaseolus vulgaris). PvDREB1A had a 777 base pairs (bp) open reading frame encoding a protein of 225 residues. The protein sequence contained a conserved DNA-binding AP2 domain of about 60 residues and a nuclear localization signal (NLS) at N-terminus site. PvDREB1A demonstrated high homology with other DREB1 members only in AP2 domain and NLS site. The phylogenetic distribution of different DREB members showed three main groups as DREB1-3 and PvDREB1A was a member of DREB1 group. Homology modeling and secondary structure analyses revealed that PvDREB1A AP2 domain was packed into the three-stranded antiparallel beta sheets (beta1-3) and an alpha helix (alpha1) almost parallel to these beta sheets. Moreover, DNA-binding AP2 domain of PvDREB1A and GCC-box containing double helix DNA were docked. The docking analysis showed that PvDREB1A AP2 domain could bind to the major groove of the DNA by three-stranded antiparallel beta sheets, with residues Gly86 or Thr87 in beta1-sheet and Arg63 or Arg64 in beta3-sheet. The docked complex also indicated that AP2 domain has a preferential for the binding of GCC stretches in the double helix DNA. A total of 36 reliably estimated hot spots residues were identified with high mutability grade but none of these residues was essential for the protein function since they are located at outside the DNA-binding AP2 domain of PvDREB1A. PMID- 27687896 TI - Delayed discharges at a major arterial centre: a 4-month cross-sectional study at a single specialist vascular surgery ward. AB - OBJECTIVES: Delayed discharges are a significant problem for the National Health Service. The objectives of this study were to determine the prevalence and impact of delayed discharge at a single specialist vascular surgery ward. DESIGN: A cross-sectional observational study. SETTING: A single specialist vascular unit in the UK during a 4-month study period (01/09/2014-31/12/2014). PARTICIPANTS: All patients admitted to the ward during the study period were included. Patients spending >=1 night on the ward once declared medically fit for discharge (MFFD) were prospectively identified and data prospectively collected. All other patients were identified retrospectively with data collected retrospectively from electronic records. OUTCOME MEASURES: Primary outcome was number of patients experiencing delayed discharge. Secondary outcome measures were length of stay, length of delay and cost of delay. RESULTS: There were 268 admissions with a total length of stay (LoS) of 2776 days. 57 admissions (21.3%) experienced delayed discharges with a total 535 excess bed days (19.3% total LoS) once MFFD. Unplanned admission (relative risk 7.3 (95% CI 2.7 to 20.0; p<0.001)) and index amputation (relative risk 9.2 (95% CI 3.8 to 22.0; p<0.001)) were associated with increased risk of delayed discharge. There were significant differences in the length of delay by the reason for the delay (p=0.01). Delay due to the provision of social services and inpatient rehabilitation were associated with longer length of delay (post hoc analysis). Age was not independently associated with either increased risk of delayed discharge or length of delay.The total estimated cost of delayed discharges during the study period was L146 055. CONCLUSIONS: A significant number of vascular patients experience delayed discharge. MFFD vascular patients occupy a high proportion of vascular beds at considerable financial cost. Unplanned admissions, amputees and those delayed due to social services contributed most to delays. Closer integration with community health and social care providers may reduce delays. PMID- 27687893 TI - LncRNA mediated regulation of aging pathways in Drosophila melanogaster during dietary restriction. AB - Dietary restriction (DR) extends lifespan in many species which is a well-known phenomenon. Long non-coding RNAs (lncRNAs) play an important role in regulation of cell senescence and important age-related signaling pathways. Here, we profiled the lncRNA and mRNA transcriptome of fruit flies at 7 day and 42 day during DR and fully-fed conditions, respectively. In general, 102 differentially expressed lncRNAs and 1406 differentially expressed coding genes were identified. Most informatively we found a large number of differentially expressed lncRNAs and their targets enriched in GO and KEGG analysis. We discovered some new aging related signaling pathways during DR, such as hippo signaling pathway-fly, phototransduction-fly and protein processing in endoplasmic reticulum etc. Novel lncRNAs XLOC_092363 and XLOC_166557 are found to be located in 10 kb upstream sequences of hairy and ems promoters, respectively. Furthermore, tissue specificity of some novel lncRNAs had been analyzed at 7 day of DR in fly head, gut and fat body. Also the silencing of lncRNA XLOC_076307 resulted in altered expression level of its targets including Gadd45 (involved in FoxO signaling pathway). Together, the results implicated many lncRNAs closely associated with dietary restriction, which could provide a resource for lncRNA in aging and age related disease field. PMID- 27687897 TI - Knowledge and practice of prostate cancer screening among general practitioners in Malaysia: a cross-sectional study. AB - OBJECTIVE: Screening for prostate cancer remains controversial. General practitioners (GPs) play an important role in assisting men to make an informed decision on prostate cancer screening. The aim of this study was to determine the knowledge and practice of prostate cancer screening among private GPs in Malaysia. DESIGN: A cross-sectional study. SETTING: Private general practices in Selangor, Malaysia. PARTICIPANTS: 311 randomly selected full-time private GPs were recruited between September 2013 and January 2014. OUTCOME MEASURES: Questionnaires were distributed to the GPs via postal mail and clinic visits. The main outcomes were: knowledge of prostate cancer risk factors and screening tests; GPs' prostate cancer screening practices; and factors influencing GPs' decision to screen for prostate cancer. Associations between covariates and propensity to screen for prostate cancer were determined using logistic regression. RESULTS: The response rate was 65%. The proportion of GPs who overestimated the positive predictive values of prostrate-specific antigen (PSA), digital rectal examination (DRE) and a combination of PSA and DRE was 63%, 57% and 64%, respectively. About 49.5% of the respondents would routinely screen asymptomatic men for prostate cancer; of them, 94.9% would use PSA to screen. Male GPs who would consider having a PSA test performed on themselves were six times more likely to screen asymptomatic men than GPs who would not have the test (OR=6.88, 95% CI 1.40 to 33.73), after adjusting for age and duration of practice. CONCLUSIONS: GPs overestimated the accuracy of PSA in prostate cancer screening. Their intention to screen for prostate cancer themselves predicted their propensity to screen their patients for prostate cancer. This finding highlights the potential of using a new approach to change GPs' screening practices via addressing GPs' own screening behaviour. PMID- 27687898 TI - Effect of modelling slum populations on influenza spread in Delhi. AB - OBJECTIVES: This research studies the impact of influenza epidemic in the slum and non-slum areas of Delhi, the National Capital Territory of India, by taking proper account of slum demographics and residents' activities, using a highly resolved social contact network of the 13.8 million residents of Delhi. METHODS: An SEIR model is used to simulate the spread of influenza on two different synthetic social contact networks of Delhi, one where slums and non-slums are treated the same in terms of their demographics and daily sets of activities and the other, where slum and non-slum regions have different attributes. RESULTS: Differences between the epidemic outcomes on the two networks are large. Time-to peak infection is overestimated by several weeks, and the cumulative infection rate and peak infection rate are underestimated by 10-50%, when slum attributes are ignored. CONCLUSIONS: Slum populations have a significant effect on influenza transmission in urban areas. Improper specification of slums in large urban regions results in underestimation of infections in the entire population and hence will lead to misguided interventions by policy planners. PMID- 27687899 TI - Central corneal thickness changes in bevel-up versus bevel-down phacoemulsification cataract surgery: study protocol for a randomised, triple blind, parallel group trial. AB - INTRODUCTION: Corneal endothelial damage following phacoemulsification is still one of the major concerns of modern day cataract surgery. Although many techniques have been proposed, the risks of posterior capsular rupture and corneal endothelium damage persist. In theory, damage to the corneal endothelium is minimised by delivering the lowest phaco energy only in the direction necessary to emulsify the lens nucleus. Hence, it is believed that the bevel of the needle should be turned towards the nucleus or the nuclear fragment (ie, bevel-down. However, there is a difference of opinion among ophthalmologists with reference to the phaco tip's position (bevel-up vs bevel-down) during phacoemulsification. This subject has not been extensively studied earlier. METHODS AND ANALYSIS: This is a prospective, triple-blinded (trial participant, outcome assessor and the data analyst), randomised controlled trial with 2 parallel groups and with an allocation ratio of 1:1. It will be conducted in a tertiary care hospital, Mangaluru, India. The objective is to compare the postoperative central corneal thickness changes between the bevel-up and bevel down techniques of phacoemulsification. Patients aged >18 years with immature cataract undergoing phacoemulsification will be selected for the study. The important exclusion criteria are the history of previous significant ocular trauma or intraocular surgery, corneal pathology, pseudoexfoliation syndrome, intraocular inflammation, a preoperative fully dilated pupil <6 mm, anterior chamber depth <2.5 mm and nuclear sclerosis grade >4. After randomisation, patients will undergo phacoemulsification surgery either by a bevel-up or bevel down procedure. With an estimated power of 80%, the calculated sample size is 55 patients in each group. The recruitment will start from April 2016. ETHICS AND DISSEMINATION: Yenepoya University Ethics Committee, India has approved the study protocol (YUEC/148/2016 on 18 February 2016). It complies with the Declaration of Helsinki, local laws and the International Council for Harmonization-good clinical practices. TRIAL REGISTRATION NUMBER: CTRI/2016/02/006691; Pre-results. PMID- 27687900 TI - Effectiveness of case management interventions for frequent users of healthcare services: a scoping review. AB - OBJECTIVE: Frequent users of healthcare services are a vulnerable population, often socioeconomically disadvantaged, who can present multiple chronic conditions as well as mental health problems. Case management (CM) is the most frequently performed intervention to reduce healthcare use and cost. This study aimed to examine the evidence of the effectiveness of CM interventions for frequent users of healthcare services. DESIGN: Scoping review. DATA SOURCES: An electronic literature search was conducted using the MEDLINE, Scopus and CINAHL databases covering January 2004 to December 2015. A specific search strategy was developed for each database using keywords 'case management' and 'frequent use'. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: To be included in the review, studies had to report effects of a CM intervention on healthcare use and cost or patient outcomes. Eligible designs included randomised and non-randomised controlled trials and controlled and non-controlled before-after studies. Studies limited to specific groups of patients or targeting a single disease were excluded. Three reviewers screened abstracts, screened each full-text article and extracted data, and discrepancies were resolved by consensus. RESULTS: The final review included 11 articles evaluating the effectiveness of CM interventions among frequent users of healthcare services. Two non-randomised controlled studies and 4 before-after studies reported positives outcomes on healthcare use or cost. Two randomised controlled trials, 2 before-after studies and 1 non-randomised controlled study presented mitigated results. Patient outcomes such as drug and alcohol use, health locus of control, patient satisfaction and psychological functioning were evaluated in 3 studies, but no change was reported. CONCLUSIONS: Many studies suggest that CM could reduce emergency department visits and hospitalisations as well as cost. However, pragmatic randomised controlled trials of adequate power that recruit the most frequent users of healthcare services are still needed to clearly confirm its effectiveness. PMID- 27687901 TI - Evidence-based interventions to reduce adverse events in hospitals: a systematic review of systematic reviews. AB - OBJECTIVE: To provide an overview of effective interventions aimed at reducing rates of adverse events in hospitals. DESIGN: Systematic review of systematic reviews. DATA SOURCES: PubMed, CINAHL, PsycINFO, the Cochrane Library and EMBASE were searched for systematic reviews published until October 2015. STUDY SELECTION: English-language systematic reviews of interventions aimed at reducing adverse events in hospitals, including studies with an experimental design and reporting adverse event rates, were included. Two reviewers independently assessed each study's quality and extracted data on the study population, study design, intervention characteristics and adverse patient outcomes. RESULTS: Sixty systematic reviews with moderate to high quality were included. Statistically significant pooled effect sizes were found for 14 types of interventions, including: (1) multicomponent interventions to prevent delirium; (2) rapid response teams to reduce cardiopulmonary arrest and mortality rates; (3) pharmacist interventions to reduce adverse drug events; (4) exercises and multicomponent interventions to prevent falls; and (5) care bundle interventions, checklists and reminders to reduce infections. Most (82%) of the significant effect sizes were based on 5 or fewer primary studies with an experimental study design. CONCLUSIONS: The evidence for patient-safety interventions implemented in hospitals worldwide is weak. The findings address the need to invest in high quality research standards in order to identify interventions that have a real impact on patient safety. Interventions to prevent delirium, cardiopulmonary arrest and mortality, adverse drug events, infections and falls are most effective and should therefore be prioritised by clinicians. PMID- 27687902 TI - Do baby boomers use more healthcare services than other generations? Longitudinal trajectories of physician service use across five birth cohorts. AB - OBJECTIVE: In light of concerns for meeting the provision of healthcare services given the large numbers of ageing baby boomers, we compared the trajectories of primary care and specialist services use across the lifecourse of 5 birth cohorts and examined factors associated with birth cohort differences. DESIGN: Longitudinal panel. SETTING: Canadian National Population Health Survey (1994 2011). POPULATION: Sample of 10 186 individuals aged 20-69 years in 1994-1995 and who were from 5 birth cohorts: Generation X (Gen X; born: 1965-1974), Younger Baby Boomers (born: 1955-1964), Older Baby Boomers (born: 1945-1954), World War II (born: 1935-1944) and pre-World War II (born: 1925-1934). MAIN OUTCOMES: Use of primary care and specialist services. RESULTS: Although the overall pattern suggested less use of physician services by each successive recent cohort, this blinded differences in primary and specialist care use by cohort. Multilevel analyses comparing cohorts showed that Gen Xers and younger boomers, particularly those with multimorbidity, were less likely to use primary care than earlier cohorts. In contrast, specialist use was higher in recent cohorts, with Gen Xers having the highest specialist use. These increases were explained by the increasing levels of multimorbidity. Education, income, having a regular source of care, sedentary lifestyle and obesity were significantly associated with physician services use, but only partially contributed to cohort differences. CONCLUSIONS: The findings suggest a shift from primary care to specialist care among recent cohorts, particularly for those with multimorbidity. This is of concern given policies to promote primary care services to prevent and manage chronic conditions. There is a need for policies to address important generational differences in healthcare preferences and the balance between primary and specialty care to ensure integration and coordination of healthcare delivery. PMID- 27687903 TI - Patient values and preferences on transcatheter or surgical aortic valve replacement therapy for aortic stenosis: a systematic review. AB - OBJECTIVE: To investigate patients' values and preferences regarding aortic valve replacement therapy for aortic stenosis. SETTING: Studies published after transcatheter aortic valve insertion (TAVI) became available (2002). PARTICIPANTS: Adults with aortic stenosis who are considering or have had valve replacement, either TAVI or via surgery (surgical aortic valve replacement, SAVR). OUTCOME MEASURES: We sought quantitative measurements, or qualitative descriptions, of values and preferences. When reported, we examined correlations between preferences and objective (eg, ejection fraction) or subjective (eg, health-related quality of life) measures of health. RESULTS: We reviewed 1348 unique citations, of which 2 studies proved eligible. One study of patients with severe aortic stenosis used a standard gamble study to ascertain that the median hypothetical mortality risk patients were willing to tolerate to achieve full health was 25% (IQR 25-50%). However, there was considerable variability; for mortality risk levels defined by current guidelines, 130 participants (30%) were willing to accept low-to-intermediate risk (<=8%), 224 (51%) high risk (>8-50%) and 85 (19%) a risk that guidelines would consider prohibitive (>50%). Study authors did not, however, assess participants' understanding of the exercise, resulting in a potential risk of bias. A second qualitative study of 15 patients identified the following factors that influence patients to undergo assessment for TAVI: symptom burden; expectations; information support; logistical barriers; facilitators; obligations and responsibilities. The study was limited by serious risk of bias due to authors' conflict of interest (5/9 authors industry-funded). CONCLUSIONS: Current evidence on patient values and preferences of adults with aortic stenosis is very limited, and no studies have enrolled patients deciding between TAVI and SAVR. On the basis of the data available, there is evidence of variability in individual values and preferences, highlighting the importance of well-informed and shared decision-making with patients facing this decision. TRIAL REGISTRATION NUMBER: PROSPERO CRD42016041907. PMID- 27687904 TI - New lanostane-type triterpenoids from the fruiting body of Ganoderma hainanense. AB - Five new lanostane-type triterpenoids, ganoderenses A-E (1-5), two new lanostane nor-triterpenoids, ganoderenses F and G (6 and 7), along with 13 known analogues (8-20) were isolated from the fruiting body of Ganoderma hainanense. Their structures were determined by combined chemical and spectral methods, and the absolute configurations of compounds 1 and 13 were confirmed by single crystal X ray diffraction. All compounds were evaluated for inhibitory activity against thioredoxin reductase (TrxR), a potential target for cancer chemotherapy with redox balance and antioxidant functions, but were inactive.

AB - BACKGROUND: The first 2 years of life is a critical period of rapid growth and brain development. During this period, nutrition and environmental factors play important roles in growth and cognitive development of a child. This report describes the study protocol of early nutrition, growth and cognitive development of infants from birth to 2 years of age. METHODS/DESIGN: This is a prospective cohort study of mothers and infants recruited from government health clinics in Seremban district in Negeri Sembilan, Malaysia. Infants are followed-up at 6, 12, 18 and 24 months of age. Pre-natal factors that include mother's pre-pregnancy body mass index, gestational weight gain, blood glucose and blood pressure during pregnancy, infant's gestational age, birth weight and head circumference at birth are obtained from patient card. Post-natal factors assessed at each follow-up are feeding practices, dietary intake, anthropometric measurements and cognitive development of infants. Iron status is assessed at 6 months, while infant temperament and home environment are assessed at 12 months. Maternal intelligence is assessed at 18 months. DISCUSSION: Early life nutritional programming is of current interest as many longitudinal studies are actively being conducted in developed countries to investigate this concept. The concept however is relatively new in developing countries such as Malaysia. This study will provide useful information on early nutrition and infant development in the first two years of life which can be further followed up to identify factors that track into childhood and contribute to growth and cognitive deviations. PMID- 27687907 TI - Value propositions of mHealth projects. AB - While mHealth holds great potential for addressing global health disparities, a majority of the initiatives never proceed beyond the pilot stage. One fundamental concern is that mHealth projects are seldom designed from the customer's perspective to address their specific problems and/or create appreciable value. A customer-centric view, where direct tangible benefits of interventions are identified and communicated effectively, can drive customer engagement and advance projects toward self-sustaining business models. This article reviews the business models of 234 mHealth projects to identify nine distinct value propositions that solve specific problems for customers. Each of these value propositions is discussed with real-world examples, analyses of their design approaches and business strategies, and common enablers as well as hurdles to surviving past the pilot stage. Furthermore, a deeper analysis of 42 mHealth ventures that have achieved self-sustainability through project revenue provides a host of practical and poignant insights into the design of systems that can fulfil mHealth's promise to address healthcare challenges in the long term. PMID- 27687908 TI - Early life adversity alters normal sex-dependent developmental dynamics of DNA methylation. AB - Studies in rodents, nonhuman primates, and humans suggest that epigenetic processes mediate between early life experiences and adult phenotype. However, the normal evolution of epigenetic programs during child development, the effect of sex, and the impact of early life adversity on these trajectories are not well understood. This study mapped the genome-wide DNA methylation changes in CD3+ T lymphocytes from rhesus monkeys from postnatal day 14 through 2 years of age in both males and females and determined the impact of maternal deprivation on the DNA methylation profile. We show here that DNA methylation profiles evolve from birth to adolescence and are sex dependent. DNA methylation changes accompany imposed weaning, attenuating the difference between males and females. Maternal separation at birth alters the normal evolution of DNA methylation profiles and targets genes that are also affected by a later stage maternal separation, that is, weaning. Our results suggest that early life events dynamically interfere with the normal developmental evolution of the DNA methylation profile and that these changes are highly effected by sex.

AB - Oxysterols are cholesterol metabolites that can be produced through enzymatic or radical processes. They constitute a large family of lipids (i.e. the oxysterome) involved in a plethora of physiological processes. They can act through GPCR (e.g. EBI2, SMO, CXCR2), nuclear receptors (LXR, ROR, ERalpha) and through transporters or regulatory proteins. Their physiological effects encompass cholesterol, lipid and glucose homeostasis. Additionally, they were shown to be involved in other processes such as immune regulatory functions and brain homeostasis. First studied as precursors of bile acids, they quickly emerged as interesting lipid mediators. Their levels are greatly altered in several pathologies and some oxysterols (e.g. 4beta-hydroxycholesterol or 7alpha hydroxycholestenone) are used as biomarkers of specific pathologies. In this review, we discuss the complex metabolism and molecular targets (including binding properties) of these bioactive lipids in human and mice. We also discuss the genetic mouse models currently available to interrogate their effects in pathophysiological settings. We also summarize the levels of oxysterols reported in two key organs in oxysterol metabolism (liver and brain), plasma and cerebrospinal fluid. Finally, we consider future opportunities and directions in the oxysterol field in order to gain a better insight and understanding of the complex oxysterol system. PMID- 27687913 TI - IL-27 attenuates airway inflammation in a mouse asthma model via the STAT1 and GADD45gamma/p38 MAPK pathways. AB - BACKGROUND: Asthma is prone to Th2-mediated chronic airway inflammation. Interleukin-27 (IL-27) is a member of the IL-12 family that promotes the differentiation of Th1 cells and inhibits Th2 cells. We use human/mouse CD4+ T cells to see whether IL-27 could inhibit IL-4 production in vitro and then observe whether IL-27 administration could alleviate allergic airway inflammation in vivo by mice asthma model. METHODS: We isolated and cultured CD4+ T cells from healthy humans and mice to test whether IL-27 could inhibit IL-4 production under different conditions. In vivo study, the effect of IL-27 was examined using two types of intra-nasal (i.n.) administration: low-dose-multiple-times prevention or high-dose-limited-times treatment in murine asthma models. The expression levels of signal transducer and activator of transcription-1 (STAT1) and growth arrest and DNA damage 45-gamma (GADD45gamma)/p38 mitogen activated protein kinase (p38 MAPK) in lung tissues were measured using qPCR and Western blotting. RESULTS: In vitro, although IL-27 could inhibit naive CD4+ T cell differentiate into Th2 cells, but it could not redifferentiate already committed Th2 cells. In vivo, preventative administration of IL-27 attenuated allergic inflammation and airway hyperreactivity, whereas treatment group had no significant effect. In the asthma group, the phosphorylation of STAT1 was impaired, while GADD45gamma and p38 MAPK exhibited no obvious changes. Preventative administration of IL-27 could either reverse the impairment of STAT1 or strengthen the expression of GADD45gamma and p38 MAPK, whereas treatment group had no significant effect. CONCLUSIONS: Preventative administration of IL-27 improved the pathological changes in mouse asthma models via both the STAT1 and GADD45gamma/p38 MAPK pathways while therapeutic administration of IL-27 had no significant effect, which may be due to the presence of already differentiated Th2 cells in asthmatic airways that resist IL-27 inhibition. PMID- 27687914 TI - Comparing the Survivability of Lactobacillus Species in Various Probiotic Delivery Vehicles. AB - BACKGROUND: Probiotics are widely used in healthy and nonhealthy individuals to maintain a favorable gut microbiome and inhibit pathogen takeover. Currently, there are many varieties of probiotic delivery vehicles on the market, with no real research indicating which is the most effective at allowing for colon colonization. In this study, we sought to determine if probiotic preparation influences the ability of Lactobacillus species, one of the most common genera of probiotic bacteria, to survive gastric acidity. OBJECTIVE: To determine the survivability of lactobacilli in stomach-level acidity for a variety of probiotic delivery vehicles. MATERIALS AND METHODS: We tested the ability of 6 different probiotic preparations-enterically encapsulated pills, nonencapsulated pills, lyophilized powder, yogurt, yogurt drink, and kefir-to enhance survivability of lactobacilli in pH 2.0-adjusted phosphate-buffered saline over time. Colony forming units were enumerated by spot plating on both nonselective (brain-heart infusion) and selective (Rogosa SL) agar. RESULTS: Regardless of delivery vehicle, lactobacilli are very capable of surviving gastric acidity, allowing for passage into the intestines. PMID- 27687915 TI - Scalable principles of community-based high-value care for seriously ill individuals: Diamonds in the rough. AB - Early, integrated palliative care has been shown to improve quality of life and reduce utilization in both inpatient and outpatient settings. As health systems shift to risk-based payment structures, palliative care will play an increasing role in improving value of care outside of the hospital. Based on successful models of community-based palliative care, we identify six principles - interdisciplinary team-based care; 24/7 access and responsiveness; concurrent palliative care with disease-directed treatment; targeting services to high-risk patients; integrated medical and social supports; and caregiver support - that are widely implemented because of their impact on improving value for seriously ill individuals.

PMID- 27687917 TI - Determinants of success in Shared Savings Programs: An analysis of ACO and market characteristics. AB - BACKGROUND: Medicare's Accountable Care Organization (ACO) programs introduced shared savings to traditional Medicare, which allow providers who reduce health care costs for their patients to retain a percentage of the savings they generate. OBJECTIVE: To examine ACO and market factors associated with superior financial performance in Medicare ACO programs. METHODS: We obtained financial performance data from the Centers for Medicare and Medicaid Services (CMS); we derived market-level characteristics from Medicare claims; and we collected ACO characteristics from the National Survey of ACOs for 215 ACOs. We examined the association between ACO financial performance and ACO provider composition, leadership structure, beneficiary characteristics, risk bearing experience, quality and process improvement capabilities, physician performance management, market competition, CMS-assigned financial benchmark, and ACO contract start date. We examined two outcomes from Medicare ACOs' first performance year: savings per Medicare beneficiary and earning shared savings payments (a dichotomous variable). RESULTS: When modeling the ACO ability to save and earn shared savings payments, we estimated positive regression coefficients for a greater proportion of primary care providers in the ACO, more practicing physicians on the governing board, physician leadership, active engagement in reducing hospital re-admissions, a greater proportion of disabled Medicare beneficiaries assigned to the ACO, financial incentives offered to physicians, a larger financial benchmark, and greater ACO market penetration. No characteristic of organizational structure was significantly associated with both outcomes of savings per beneficiary and likelihood of achieving shared savings. ACO prior experience with risk-bearing contracts was positively correlated with savings and significantly increased the likelihood of receiving shared savings payments. CONCLUSIONS: In the first year, performance is quite heterogeneous, yet organizational structure does not consistently predict performance. Organizations with large financial benchmarks at baseline have greater opportunities to achieve savings. Findings on prior risk bearing suggest that ACOs learn over time under risk-bearing contracts. IMPLICATIONS: Given the lack of predictive power for organizational characteristics, CMS should continue to encourage diversity in organizational structures for ACO participants, and provide alternative funding and risk bearing mechanisms to continue to allow a diverse group of organizations to participate. LEVEL OF EVIDENCE: III. PMID- 27687918 TI - Does laminar airflow make a difference to the infection rates for lower limb arthroplasty: a study using the National Joint Registry and local surgical site infection data for two hospitals with and without laminar airflow. AB - This study compared the National Joint Registry for England, Wales, Northern Ireland and the Isle of Man (NJR) data for total hip replacements (THRs) and total knee replacements (TKRs) from Hospital A [with laminar airflow (LAF)] and Hospital B (without LAF). These hospitals were originally managed by two different trusts that subsequently merged. Consequently, the theatres in Hospital A have always had LAF and those in Hospital B had only conventional ventilation systems. As this merger happened before the establishment of the NJR, it puts us in a unique position, enabling direct comparison of the revision rates for infected hip and knee replacements between the two hospitals that follow similar infection protocols. Analysis of the NJR data showed there were no statistical differences. Of the 2234 TKRs performed at Hospital A, 16 were revised for infection, whereas 19 of the 3694 TKRs at Hospital B were revised (p < 0.33). Of the 1752 THRs at Hospital A, 5 were revised for infection, whereas this was the case for 12 of the 3163 THRs at Hospital B (p < 0.59). There was also no statistical difference when combining the figures for TKRs and THRs (p < 0.59). Our local surgical site infection (SSI) data from these two hospitals were also analysed. Again, there was no statistical difference between the two sites (p < 0.34). Using LAF has not reduced the rate of revision for infection nor it has reduced the incidence of SSI in our theatres. This is the first study comparing infection rates in two different hospitals serving similar patient populations using the NJR and SSI data. Our study questions the rationale of increasing use of LAF in routine lower limb arthroplasty. We call for greater debate and more robust studies on the subject. PMID- 27687919 TI - Bone density of elbow joints in Labrador retrievers and Golden retrievers: Comparison of healthy joints and joints with medial coronoid disease. AB - The aims of this study were: (1) to determine the inter-observer repeatability of particular regions of the canine elbow joints; (2) to assess the effect of age, bodyweight and breed on bone density in healthy young dogs; (3) to compare Hounsfield units (HU) and bone density (BD) measurements between normal elbow joints and diseased elbow joints; and (4) to determine the sensitivity and specificity for HU and BD measurements in specific regions in the canine elbow joint. Regions with the highest repeatability were located at the medial coronoid process (MCP) base and apex, and at the level of the humerus, on the sagittal and sagittal oblique planes of the elbow joint. Age and breed were significantly associated with several regions of interest; conversely, none of the measurements were associated with bodyweight. Increased HU and BD values in the MCP base and apex regions are likely to be related to medial coronoid disease. Labrador retrievers had higher HU and BD values than Golden retrievers and an increase in BD was found in older animals. Cut-offs determined with receiver operating characteristic plots of the MCP base and apex suggested fairly good sensitivity and specificity (base: area under the curve 0.85, sensitivity 75.0%, specificity 88.8%; apex: area under the curve 0.89, sensitivity 80.0%, specificity 92.5%). PMID- 27687920 TI - Responses to diagnostic tests for bovine tuberculosis in dairy and non-dairy cattle naturally exposed to Mycobacterium bovis in Great Britain. AB - Field surveillance of British cattle using the single intradermal comparative cervical tuberculin (SICCT) test shows a higher incidence rate of bovine tuberculosis (bTB) in dairy compared to beef herds, but a lower probability of post-mortem examination confirmed (PMC) Mycobacterium bovis infection in dairy herds. A cross-sectional study was conducted to compare animal level differences in bTB detection between dairy and non-dairy cattle in Great Britain. During the period from 2002 to 2005, 200 (41% dairy) reactors in the SICCT test (standard interpretation) were randomly selected, and 200 in-contact cattle (43% dairy) were purposively selected from bTB-infected herds. Interferon (IFN)-gamma responses in blood to bovine and avian purified protein derivative (PPD), and early secretory antigen target 6 kDa and culture filtrate protein 10 (ESAT 6/CFP10), were measured. The post-mortem examination included gross pathological examination, mycobacterial culture and histopathology. The proportions of cattle positive to ESAT6/CFP10 were 26% (95% confidence interval, CI, 15-39%) in dairy reactors and 62% (95% CI 51-72%) in non-dairy reactors (P <0.001). PMC risk was 34% (95% CI 24-45%) in dairy reactors and 69% (95% CI 60-78%) in non-dairy reactors (P <0.001). The odds ratio for PMC risk in dairy reactors compared to non-dairy reactors, after controlling for bTB prevalence, herd size and SICCT test response, was 0.27 (95% CI 0.14-0.53; P <0.001). In surveillance data, adjusted animal level PMC risks were lower for dairy reactors than for beef reactors aged >2 years (P <0.001). PMID- 27687921 TI - Effects of preoperative carprofen on cardio-respiratory, hormonal and metabolic stress response in calves during umbilical surgery under isoflurane inhalation anaesthesia. AB - The aim of this study was to examine the effects of preoperative carprofen on the cardiorespiratory, hormonal and metabolic stress response during umbilical surgery under isoflurane anaesthesia combined with local anaesthesia, in calves. A randomised, blinded experimental study was conducted in 24 calves. Carprofen (n = 12; 1.4 mg/kg) or physiological saline solution (controls; n = 12) was administered 1 h prior to surgery. Anaesthesia was induced with xylazine (0.1 mg/kg, IM) and, after the onset of sedation (i.e. after 5-8 min), ketamine was administered (2 mg/kg, IV). Anaesthesia was then maintained with isoflurane (ISO) in oxygen to effect and completed by infiltration of the incision line with 20 mL of 2% procaine. Cardiorespiratory, endocrine and metabolic parameters were examined before, during and after surgery at short intervals. In both groups, anaesthesia appeared adequate for the surgical intervention. Heart rate, stroke index and arterial blood pressure were significantly elevated after the onset of surgery. Oxygen partial pressure and oxygen delivery increased, while the oxygen extraction ratio decreased intraoperatively, ensuring sufficient oxygen supply. In the control group, the mean surge in serum cortisol concentrations tended to be higher (P = 0.089) and systemic vascular resistance (SVR) was significantly greater (P <0.05) than in the carprofen group during surgery. In conclusion, the anaesthetic protocol used in this study induced reliable analgesia in both groups. The lower serum cortisol levels and SVR may indicate a reduced surgical stress response in calves undergoing umbilical surgery under ISO anaesthesia after administering carprofen preoperatively. PMID- 27687922 TI - Elimination of virulent strains (aprV2) of Dichelobacter nodosus from feet of 28 Swiss sheep flocks: A proof of concept study. AB - Virulent ovine footrot caused by Dichelobacter nodosus is an endemic disease worldwide. It is associated with severe pain, impaired animal welfare and economic losses. The competitive real-time PCR for the differentiation of virulent aprV2 and benign aprB2 strains of Dichelobacter nodosus provides an objective, rapid and sensitive diagnostic tool for footrot surveillance, especially as it enables early detection of subclinical carriers of virulent strains. The aim of this study was to evaluate the feasibility of complete elimination of Dichelobacter nodosus strains carrying the aprV2 gene from sheep flocks. The treatment protocol was based on careful removal of loose and severely overgrown claw horn, weekly stand-in foot baths of the entire flock for 10 min per sheep, using a 10% zinc sulphate disinfectant solution, clinical and PCR follow-up and isolation or culling of non-responders. Dichelobacter nodosus strains carrying the aprV2 gene were successfully eliminated from the feet of the sheep of all 28 flocks (100%) participating in the study within 6-19 weeks of weekly foot bathing. A strong correlation between the length of time for weekly foot bathing to eliminate the virulent strains and the within-flock prevalence of clinical footrot at the beginning was observed (rho, 0.68; P <0.001). A statistically significant correlation was not detected between flock size and the length of time for weekly foot bathing (rho, 0.28; P = 0.14), or the prevalence of clinical footrot at study commencement (rho, -0.04; P = 0.82), respectively. In conclusion, a complete elimination of Dichelobacter nodosus strains carrying the aprV2 gene in sheep flocks was possible with a protocol based on careful trimming, weekly stand-in foot baths, and identification of infection using a specific PCR-test and isolation or culling of non-responders. PMID- 27687923 TI - Diagnostic accuracy of a smartphone electrocardiograph in dogs: Comparison with standard 6-lead electrocardiography. AB - The diagnostic accuracy of a smartphone electrocardiograph (ECG) in evaluating heart rhythm and ECG measurements was evaluated in 166 dogs. A standard 6-lead ECG was acquired for 1 min in each dog. A smartphone ECG tracing was simultaneously recorded using a single-lead bipolar ECG recorder. All ECGs were reviewed by one blinded operator, who judged if tracings were acceptable for interpretation and assigned an electrocardiographic diagnosis. Agreement between smartphone and standard ECG in the interpretation of tracings was evaluated. Sensitivity and specificity for the detection of arrhythmia were calculated for the smartphone ECG. Smartphone ECG tracings were interpretable in 162/166 (97.6%) tracings. A perfect agreement between the smartphone and standard ECG was found in detecting bradycardia, tachycardia, ectopic beats and atrioventricular blocks. A very good agreement was found in detecting sinus rhythm versus non-sinus rhythm (100% sensitivity and 97.9% specificity). The smartphone ECG provided tracings that were adequate for analysis in most dogs, with an accurate assessment of heart rate, rhythm and common arrhythmias. The smartphone ECG represents an additional tool in the diagnosis of arrhythmias in dogs, but is not a substitute for a 6-lead ECG. Arrhythmias identified by the smartphone ECG should be followed up with a standard ECG before making clinical decisions. PMID- 27687924 TI - Evaluation of three competitive ELISAs and a fluorescence polarisation assay for the diagnosis of bovine brucellosis. AB - Bovine brucellosis is an infectious disease of worldwide public health and economic importance. The usual tests for the diagnosis of this disease include the Rose-Bengal test (RBT), complement fixation test (CFT), serum agglutination test (SAT) and indirect ELISA. New tests such as competitive ELISAs (C-ELISA) and fluorescence polarisation assay (FPA) have been developed. However, C-ELISA may correspond to different protocols and a wide variation may exist in their diagnostic performance. The aim of this study was to evaluate three commercially available C-ELISA kits (C-ELISA1-3) and FPA for the diagnosis of bovine brucellosis and compare test performance with RBT, CFT, indirect ELISA and FPA. Sera submitted to EU laboratories in 2011 from 5111 adult cattle were tested. Individual test sensitivities (Se) and specificities (Sp) were estimated. Threshold assessment using the receiver operating characteristic method was also performed. The most sensitive tests were FPA (99.0%; 95% confidence interval [CI], 97.9-100%), C-ELISA1 (98.4%; 95% CI, 97.0-99.8%) and RBT (97.7%; 95% CI, 95.9-99.3%). The most specific tests were CFT (99.98%; 95% CI, 99.93-100%), SAT (99.98%; 95% CI, 99.93-100%) and RBT (99.89%; 95% CI, 99.79-99.99%). Among the new tests, none of the three C-ELISA kits studied could be recommended as a single screening test because of their low specificity, especially when used in a herd. C-ELISA3 could not be recommended as confirmatory test on individual animals to determine whether false positive serological test results had occurred. PMID- 27687925 TI - Quantitative analysis of infiltrating immune cells and bovine papillomavirus type 1 E2-positive cells in equine sarcoids. AB - Sarcoids are the most frequently observed skin tumours in equids and consist of cutaneous accumulations of transformed fibroblasts. Their aetiopathogenesis is closely linked to a presumably abortive infection by bovine papillomavirus (BPV) types 1 and 2. In cattle, dermal fibropapillomas induced by BPV1/2 usually regress spontaneously due to a local, cell-mediated, immune response; however, equids appear to lack an effective immune response to BPV1/2 and mechanisms of immune evasion have been postulated. As a consequence, equine sarcoids tend to persist and are prone to recur. In this study, cryosections were analysed by immunofluorescent staining and a high content analysis system to determine the presence and distribution of CD4(+), CD8(+), FoxP3(+), RORgammat(-), CD206(+) and CD14(+) cells, along with expression of the BPV1 early regulatory protein E2. A higher density of cells was positive for BPV1 E2(+) within the transformed tissue than in perilesional tissue or normal skin of horses with sarcoids and control horses. The proportion of CD8(+) cytotoxic T cells was significantly increased in perilesional and lesional tissues, whereas CD4(+) T helper cells were present in higher density only in lesional tissue compared to normal skin from horses with and without sarcoids. The proportion of pro-inflammatory CD4(+)FoxP3(+)RORgammat(+) regulatory T cells was decreased in sarcoid tissue compared to perilesional, distant and control tissue. There were no significant differences in densities of CD4(+)FoxP3(+) RORgammat(-) regulatory T cells between sarcoids and control tissues. Equine sarcoids are characterised by infiltrations of CD8(+) and CD4(+) T cells, with decreased representation by pro inflammatory CD4(+)FoxP3(+)RORgammat(+) regulatory T cells. PMID- 27687926 TI - A novel set of behavioural indicators for measuring perception of food by cats. AB - Behavioural indicators provide a promising approach for objective assessment of the perceptions of animals. In cats, the frequency of specific behaviours as indicators of perception has been studied in connection with food palatability. The aim of this study was to expand that knowledge by identifying behavioural indicators correlating with three degrees of palatability. Thirty-four pet cats were presented with three types of items: favoured food (FF), favoured food with a placebo mini-tablet hidden inside (TFF) and non-favoured food (NFF). The items were presented in a pseudo-randomised sequence, with six trials per item and 18 trials per cat. The behaviour of cats before, during and after eating, or refusing to eat, was video-recorded. Two trained observers, blinded to the types of food items, independently determined the frequency of 16 behavioural patterns on the video recordings. The data were analysed using a mixed logistic regression model. Five behavioural patterns differentiated FF from NFF; 'flick ears backwards', 'lick nose, not eaten', 'flick tail' and 'groom body' were more frequent with NFF, whereas 'lick lips' was more frequent with FF. One indicator, 'drop item', was more frequent with TFF than FF. These findings provide evidence of new behavioural indicators for objective assessment of food perception in cats. The findings also have practical applicability in designing a novel palatability test to be utilised in developing veterinary pharmaceuticals with improved palatability for cats. PMID- 27687927 TI - Existence of bovine neonatal pancytopenia before the year 2005? Retrospective evaluation of 215 cases of haemorrhagic diathesis in cattle. AB - Haemorrhagic diathesis (HD) in cattle is a relatively rare syndrome that can have many different causes. With the occurrence of bovine neonatal pancytopenia (BNP) in 2007, the number of cases of HD in cattle has increased. This led to an enhanced interest in diseases presenting with bleeding disorders. The possible causes of HD in cattle, the clinical findings, and the course of various diseases are described and evaluated. Furthermore, we determined whether cases of BNP occurred before the introduction of the vaccine Pregsure BVD since its widespread use was associated with the syndrome. Records of 215 cases of HD in cattle that had been referred to the Clinic for Ruminants with Ambulatory and Herd Health Services at the Centre for Clinical Veterinary Medicine, Ludwig Maximilian University, Munich, between 1982 and 2014 were evaluated. The two most commonly diagnosed diseases were BNP (n = 95) and septicaemia (n = 35), with fatality rates of 82% and 66%, respectively. In 27 (13%) cases, no clear cause for the HD could be designated. Statistically significant differences were found with regard to the course of the various disorders and the clinical findings. A receiver operating characteristic analysis of thrombocyte counts of affected animals at the time of arrival at the clinic did not provide any predictive information on disease outcome. Two cases of HD occurred before the introduction of Pregsure BVD (1989, 1991). In both cases, clinical, haematological, and pathological findings were identical to BNP. The cause of HD in these two cases could not be determined retrospectively. PMID- 27687928 TI - Bovine spastic paresis: A review of the genetic background and perspectives for the future. AB - Bovine spastic paresis (BSP) is a sporadic, progressive neuromuscular disease that is thought to affect all breeds of cattle. The disease manifests as a unilateral or bilateral hyperextension of the hind limb due to increased muscle tone or permanent spasm of mainly the gastrocnemius and/or the quadriceps muscle. Clinical signs only appear in rising, standing and moving animals, which is an important diagnostic feature. Although several medical treatments have been described, surgical procedures such as neurectomy or tenectomy are generally indicated. Even though complete recovery can be achieved, BSP-affected animals should not be used for breeding, since BSP is commonly considered a hereditary disease. The condition therefore negatively affects animal welfare, economics and breeding. When first described in 1922, BSP was already assumed to be heritable, and this assumption has been perpetuated by subsequent authors who have only discussed its possible modes of inheritance, which included monogenetic and polygenetic modes and gene-environment interactions. Besides some clinical aspects and the consideration of the tarsal joint angle as a BSP-correlated trait, this review mainly focuses on the assumed genetic aspects of BSP. Evaluation of the published literature demonstrates that to date, irrevocable proof for the assumed heritability of BSP is still missing. The assumption of heredity is further contradicted by known allele frequencies and incidences of proven hereditary diseases in cattle, such as arachnomelia or bovine spinal muscular atrophy. Consequently, future research is needed to determine the cause of spastic paresis. Procedures that will help test the null-hypothesis ('BSP is not hereditary') and possible modes of inheritance are discussed in this review. PMID- 27687929 TI - Serum biochemistry profile, inflammatory cytokines, adipokines and cardiovascular findings in obese dogs. AB - The aim of this study was to evaluate the serum biochemistry profile, inflammatory cytokines, adipokines and cardiovascular findings in obese dogs. Twenty obese and 20 normal weight healthy pet dogs were recruited into the study, where they underwent blood testing and assessment of cardiovascular function (blood pressure analysis, electrocardiography and echocardiography). Higher concentrations of total cholesterol, triglycerides, lactate dehydrogenase, total serum proteins, alpha-globulins, total bilirubin, insulin, insulin:glucose ratio, alkaline phosphate and alanine aminotransferase were observed in obese dogs than dogs of normal weight. There were no differences in concentrations of tumour necrosis factor (TNF)-alpha or interleukin (IL)-6 between the two groups. Obese dogs had higher serum leptin but lower adiponectin concentrations than dogs of normal weight. Systolic arterial blood pressure was higher in obese dogs than dogs of normal weight. The values for the thickness of the free wall of the left ventricle and interventricular septal thickness were greater at end-diastole in obese dogs compared to dogs of normal weight. Four of 20 obese dogs were determined to have obesity-related metabolic dysfunction (ORMD). The findings indicate that a chronic inflammatory state is not necessarily evident in obese dogs, as has been described in human beings, and the criteria used for ORMD can be used to define this syndrome in dogs. In this study, canine obesity was associated with cardiac and vascular dysfunction. PMID- 27687930 TI - Challenging conventional wisdom with vigour. PMID- 27687931 TI - Claw health and prevalence of lameness in cows from compost bedded and cubicle freestall dairy barns in Austria. AB - Claw health and lameness data from five dairies with compost bedded barns (n = 201 data sets) were evaluated and compared with data from five dairy herds housed in freestall cubicle barns (n = 297 data sets). They were matched for having the same cow numbers, flooring type and similar milk yield. The prevalence of lameness, claw lesions and their severity grades were analysed. Two claw health indicators, the cow claw score (CCS) and the farm claw score (FCS), were calculated using a computerised claw trimming database programme; there was no significant difference in overall lameness prevalence in cows from five compost bedded barns (18.7%) compared to cows from five freestall cubicle herds (14.9%). A cumulative link mixed model (CLMM) did not show significant differences in locomotion between different types of bedding material, flooring system, breed, visit number, observer and time since last trimming, but locomotion was significantly influenced by CCS. Another CLMM tested the impact of parameters mentioned on CCS and showed significant influence of flooring type, visit number and cattle breed. Statistically significant differences in the prevalence of claw disorders between compost bedded and freestall cubicle barns were found for white line disease (WLD; 20.4% and 46.6%, respectively), heel horn erosion (HHE; 26.9% and 59.9%, respectively), concave dorsal wall as a result of chronic laminitis (6.5% and 15.9%, respectively) and for interdigital hyperplasia (0.2% and 3.1%, respectively). The results of this study indicate that compost dairy barns are a good alternative to common cubicle housing systems in terms of lameness, claw health and animal welfare. PMID- 27687932 TI - Bioluminescent avian pathogenic Escherichia coli for monitoring colibacillosis in experimentally infected chickens. AB - Avian pathogenic Escherichia coli (APEC) are responsible for significant economic losses in the poultry industry. In this study, a model for investigating the pathogenesis of APEC infections was established. APEC strain CH2 (O78) was marked with the luciferase operon (luxCDABE) using a Tn7 transposon and tissues of experimentally infected chickens were analysed for a correlation between the bioluminescent signal and the number of bacteria. Transposition of the lux operon into the chromosome of the APEC isolate did not affect sensitivity to lytic bacteriophages and there was no effect on virulence in an intratracheal infection model in 1-day-old chicks, although results with a subcutaneous infection model were inconclusive. A correlation between the number of bacteria and the luminescent signal was found in liquid medium, as well as in homogenised heart, liver, spleen and lung of 4-week-old experimentally infected chickens. This study showed that lux could be used for identification of the infecting strain after experimental infection with APEC in poultry. PMID- 27687933 TI - Controlled trial of whole body protein synthesis and plasma amino acid concentrations in yearling horses fed graded amounts of lysine. AB - Lysine has been reported as the first limiting amino acid in typical equine diets. Indicator amino acid oxidation (IAAO) has become the standard method for determining amino acid requirements in other species, but prior to this study, it has not been used to determine equine requirements. The aim of this study was to evaluate whole body protein synthesis and plasma and muscle amino acid concentrations in response to graded levels of lysine intake in yearling horses. Six Thoroughbred colts (358 +/- 5 kg) were fed each of six treatment lysine intakes ranging from 76 to 136 mg/kg body weight/day. Blood samples were taken before and 90 min after the morning concentrate meal. Gluteal muscle biopsies were taken ~100 min after the morning concentrate meal. The next day, whole body phenylalanine kinetics were determined using a 2 h primed, constant infusion of [(13)C] sodium bicarbonate followed by a 6 h primed, constant infusion of [1 (13)C] phenylalanine. Plasma lysine concentrations increased linearly (P <0.05) at both the 0 and 90 min time points with increasing lysine intakes. Free muscle asparagine, aspartate, arginine, glutamine, lysine, taurine and tryptophan concentrations responded quadratically to lysine intake (P <0.05). Phenylalanine kinetics did not differ between treatment intakes (P > 0.10). A broken line analysis of lysine intake and phenylalanine oxidation failed to yield a breakpoint from which to determine a lysine requirement. These diets may have been limiting in an amino acid other than lysine, underscoring the lack of data concerning amino acid requirements and bioavailability data in the horse. PMID- 27687934 TI - Distortion product otoacoustic emissions in geriatric dogs. AB - Recordings of distortion product otoacoustic emissions (DPOAE) were taken from 28 geriatric dogs aged 12.2 +/- 2.2 years and 15 control dogs aged 5.9 +/- 3.0 years (mean +/- standard deviation) to demonstrate frequency-specific changes in cochlear responses. Recordings were performed for primary frequencies of 2-12 kHz in 2 kHz increments. Brainstem auditory evoked response (BAER) recordings were also made from geriatric dogs for comparison with DPOAE responses. Significant decreases in DPOAE response amplitudes were observed at frequencies of 6-12 kHz in geriatric dogs compared to control dogs, reflecting loss of cochlear outer hair cells along the length of the cochlea. Significant decreases in response amplitudes were not seen at frequencies of 2 or 4 kHz. Decreases in BAER response amplitudes subjectively paralleled the depressed DPOAE amplitudes. No significant linear regression relationships were found for DPOAE response amplitude vs. age despite the progressive nature of age-related hearing loss. The reductions in response at all frequencies starting at the age where dogs are considered geriatric indicate that age-related hearing loss begins earlier in the life span. DPOAE recordings provide a means to assess cochlear function across different portions of the auditory spectrum for assessing hearing loss associated with aging, and potentially for losses from other causes of decreased auditory function.

AB - In cats, lymphoma (lymphosarcoma) is the most common neoplasm affecting the spinal cord and the second most common intracranial tumour. Although lymphoma commonly develops in the spinal cord as a part of a multicentric process, a primary form may occur. Lymphoma can exhibit a wide range of morphological patterns, including intraparenchymal brain mass, lymphomatosis cerebri, intravascular lymphoma, lymphomatous choroiditis and meningitis, extradural, intradural-extramedullary or intramedullary lymphoma in the spinal cord, or neurolymphomatosis in the peripheral nerves. Lymphoma may occur as a paraneoplastic disorder associated with peripheral neuropathies. Magnetic resonance imaging (MRI) and computed tomography (CT) are the techniques of choice for morphological assessment of nervous system lesions in vivo. However, biopsy should be performed to achieve a definitive diagnosis. Knowledge of the different morphological patterns expressed by lymphoma in the nervous system of cats allows veterinary clinicians to suspect lymphoma and to arrange appropriate diagnostic procedures, including immunophenotype and clonality studies, along with therapeutic protocols and prognostic evaluations. PMID- 27687937 TI - Prevalence and antimicrobial susceptibility of bacterial isolates from horses with synovial sepsis: A cross-sectional study of 95 cases. AB - Bacterial culture and antimicrobial susceptibility testing of septic synovial samples allows instigation of targeted antimicrobial therapy; however, bacterial culture takes more than 24 h and has low sensitivity. This study aimed to identify the most frequently cultured bacteria and their antimicrobial susceptibility profile from septic synovial samples in our referral equine hospital, to allow recommendations regarding appropriate initial antimicrobial therapy prior to culture results. Hospital records for all horses with synovial sepsis and a synovial sample submitted to the microbiology laboratory between 2004 and 2013 were retrieved (n= 379 samples). One horse had positive cultures from more than one synovial structure, and two horses had positive cultures obtained from repeat samples. Overall, 114 bacterial isolates were obtained. Gram positive bacteria were isolated in 75% of cases, of which 22% were haemolytic Staphylococcus spp., and 52% were Staphylococcus aureus including two multidrug resistant isolates. Gram-negative bacteria were isolated from 25% of cases. Anaerobic Clostridium spp. was isolated in 3% of cases. Of the first line antimicrobials, oxytetracycline and doxycycline were effective against 70-100% of the Gram-positive bacteria and 20-100% of the Gram-negative organisms, whilst trimethoprim-sulphamethoxazole and gentamicin efficacy ranged between 50% and 88% for both Gram-positive and Gram-negative bacteria. Of the equine protected antimicrobials, ceftiofur was effective against 70-90% of all bacterial isolates whilst 80% of isolates were susceptible to enrofloxacin. These results indicate that tetracyclines, trimethoprim-sulphamethoxazole or gentamicin may be suitable first-line antimicrobials for treatment of synovial sepsis cases while awaiting laboratory results, findings which support current recommendations for antimicrobial stewardship in equine medicine. PMID- 27687938 TI - Expression of microRNAs miR-21 and miR-181c in cerebrospinal fluid and serum in canine meningoencephalomyelitis of unknown origin. AB - The potential of microRNAs (miRNAs) as biomarkers for canine meningoencephalomyelitis of unknown origin (MUO) was investigated by using quantitative real-time (qRT)-PCR to determine the expression of microRNA-21 (miR 21) and microRNA-181c (miR-181c) in the cerebrospinal fluid (CSF) of dogs. Dogs with MUO (n = 10) had higher levels of expression of miR-21 and miR-181c in the CSF than dogs with non-inflammatory neurological diseases (n = 8). There was a positive correlation between CSF cellularity and expression of miRNAs in the CSF, particularly for miR-21 in the MUO group. PMID- 27687939 TI - Equine atypical myopathy: A metabolic study. AB - Atypical myopathy (AM) is a potentially fatal disease of grazing horses. It is reportedly caused by the ingestion of sycamore seeds containing toxic hypoglycin A. In order to study metabolic changes, serum and urine samples from nine horses with atypical myopathy and 12 control samples from clinically healthy horses were collected and then analysed using a high-performance liquid chromatography coupled with tandem mass spectrometry; serum metabolic profiles as the disease progressed were also studied. Metabolic data were evaluated using unsupervised and supervised multivariate analyses. Significant differences were demonstrated in the concentrations of various glycine conjugates and acylcarnitines (C2-C26). Moreover, the concentrations of purine and pyrimidine metabolites, vitamins and their degradation products (riboflavin, trigonelline, pyridoxate, pantothenate), and selected organic and amino acids (aspartate, leucine, 2-oxoglutarate, etc.) were altered in horses with AM. These results represent a global view of altered metabolism in horses with atypical myopathy. PMID- 27687940 TI - Detection of Yersinia enterocolitica serotype O:9 in the faeces of cattle with false positive reactions in serological tests for brucellosis in Ireland. AB - Intestinal infection by Yersinia enterocolitica serotype O:9 (YeO9) in cattle has been linked to false positive serological reactivity (FPSR) in diagnostic tests for brucellosis. Although eradicated in Ireland, brucellosis monitoring still identifies seropositive animals, usually one or two (termed singletons) per herd, which are classed as FPSR. To investigate a link between FPSR and YeO9, faeces and blood were collected from singleton FPSR cattle, and from companion animals, in eight selected herds with more than one FPSR animal, for YeO9 culture and Brucella serology. YeO9 was isolated from 76/474 (16%) FPSR singletons in 309 herds, but not from any of 621 animals in 122 control non-FPSR herds. In the FPSR herds 52/187 (27.8%) animals were culture positive, and 17% of the isolates were from seronegative animals. Seropositive animals were more likely to have a rising antibody titre when culture positive. PMID- 27687941 TI - Differential secretion of adipokines from subcutaneous and visceral adipose tissue in healthy dogs: Association with body condition and response to troglitazone. AB - This study aimed to determine the effects of body condition, fat depot, and a peroxisome proliferator-activated receptor gamma-agonist (troglitazone) on secretion of adiponectin, interleukin-6 (IL6), and tumor necrosis factor-alpha (TNFalpha) from adipose tissue of healthy dogs. Subcutaneous and omental visceral adipose tissue samples were collected from 16 healthy intact female dogs, and body condition score (range 4-8/9) was determined. Concentrations of adiponectin were measured in mature adipocytes cultures and concentrations of IL6 and TNFalpha were measured in stromovascular cells cultures after 48 h incubation in fresh control medium, or fresh medium containing 10 uM troglitazone. Mature adipocytes and stromovascular cells of subcutaneous origin secreted higher concentrations of adiponectin and lower concentration of IL6 and TNFalpha, respectively, than corresponding cells of visceral origin, in both the control (P = 0.015, P = 0.004, and P = 0.016, respectively) and troglitazone-treated cultures (P <0.001, P = 0.004, and P = 0.016, respectively). Troglitazone increased adiponectin secretion from mature adipocytes in visceral (P = 0.019), but not in subcutaneous fat cultures (P = 0.4). Troglitazone decreased IL6 and TNFalpha secretion from stromovascular cells both in visceral (P = 0.047 and P = 0.016, respectively) and subcutaneous (P = 0.047 and P = 0.016, respectively) fat cultures. Higher body condition score was associated with lower secretion of adiponectin from mature adipocytes (P = 0.007), lower secretion of IL6 (P = 0.040) and higher secretion of TNFalpha (P = 0.040) from stromovascular cells. This study showed differential secretion of adipokines by subcutaneous and visceral fat depots in dogs and association between body condition and adipokine secretion. Activation of PPARgamma altered adipokine secretion. PMID- 27687942 TI - Mycoplasma mastitis in cattle: To cull or not to cull. AB - Bovine mastitis caused by mycoplasmas, in particular Mycoplasma bovis, is a major problem for milk production and animal welfare in large dairy herds in the USA and a serious, although sporadic, disease in Europe and the Middle East. It causes severe damage to the udder of cattle and is largely untreatable by chemotherapy. Mycoplasma mastitis has a distinct epidemiology and a unique set of risk factors, the most important of which is large herd size. The disease is often self-limiting, disappearing within months of outbreaks, sometimes without deliberate intervention. Improved molecular diagnostic tests are leading to more rapid detection of mycoplasmas. Typing tests, such as multi-locus sequence typing, can help trace the source of outbreaks. An approach to successful control is proposed, which involves regular monitoring and rapid segregation or culling of infected cows. Serious consideration should be given by owners of healthy dairy herds to the purchase of M. bovis-free replacements. Increased cases of disease could occur in Europe and Israel if the trend for larger dairy herds continues. PMID- 27687943 TI - T-cell factor-4 and MHC upregulation in pigs receiving a live attenuated classical swine fever virus (CSFV) vaccine strain with interferon-gamma adjuvant. AB - The effect of co-administration of interferon (IFN)-gamma in pigs undergoing vaccination with an attenuated strain (LPC) of classical swine fever virus (CSFV) was investigated. Unvaccinated pigs demonstrated pyrexia and died 7-9 days after challenge with virulent CSFV. Pigs receiving the attenuated vaccine remained healthy after virus challenge, except for mild, transient pyrexia, whereas pigs receiving IFN-gamma simultaneously with the vaccine demonstrated normal body temperatures after virus challenge. Examination by nested RT-PCR revealed greater viral load in the spleens of the pigs vaccinated with the attenuated CSFV, compared with those that had additionally received IFN-gamma. Expression of major histocompatibility complex (MHC) class I and MHC class II molecules was upregulated in the spleens of the IFN-gamma treated vaccinated pigs, demonstrated by immunohistochemistry. Based on Western blot analysis, anti-CSFV IgG2 antibodies were elevated in vaccinated pigs by co-administration of IFN-gamma (IFN-gamma(Hi): P < 0.01; IFN-gamma(Lo): P <0.05). By employing the suppression subtractive hybridization technique, RT-PCR, in situ hybridization, and immunohistochemistry, T-cell factor-4 (Tcf-4) mRNA and protein expression were found to be upregulated in the spleens of vaccinated pigs that had received IFN gamma. This study suggests involvement of Tcf-4 in IFN-gamma-mediated immune regulation following CSFV vaccination. PMID- 27687944 TI - Comparison of treatment outcomes for superficial digital flexor tendonitis in National Hunt racehorses. AB - Superficial digital flexor (SDF) tendonitis is a common injury in Thoroughbred racehorses. Injuries require prolonged rehabilitation, with unpredictable outcomes and a high incidence of re-injury. This observational case-control study aimed to compare race outcomes after commonly advocated treatments for tendon healing. Clinical and racing records were evaluated for 127 National Hunt racehorses treated between 2007 and 2011 for an SDF tendon injury. Two age- and sex-matched control horses were selected for each case horse to analyse the effect on post-injury racing outcomes of pre-injury data, lesion severity and treatment group [controlled exercise alone, bar firing, intralesional platelet rich plasma (PRP), tendon splitting, tendon splitting combined with bar firing]. Control horses raced more often than case horses, with higher maximum racing post rating (RPRmax) and longer racing distances. Pre-injury racing performance was not associated with treatment group. Rate of return to racing was not associated with lesion severity or treatment group. Number of races, total distance raced post-injury and RPRmax were not associated with lesion severity or treatment group. Controlled exercise alone offered similar post-injury racing outcomes in National Hunt racehorses with SDF tendonitis to the other treatment options examined. Bar firing, either alone or in conjunction with tendon splitting, provided no additional benefit in rate of return to racing and race performance. PMID- 27687945 TI - Management factors associated with mortality of dairy calves in Finland: A cross sectional study. AB - Mortality at herd level is an indicator of overall calf welfare on dairy farms. The aim of this cross sectional study was to identify management factors associated with calf mortality on dairy farms in Finland. Calf mortality data and information on management practices collected during farm visits and farmer interviews were analysed using linear models. The average size of 82 herds enrolled in the study was 125 +/- 41 cows. The mortality risk of calves <7 days of age was 5 (or 5.2) +/- 2.3% and was associated with larger herd size and the practice of not separating sick calves from other calves (6.0 +/- 0.4 vs. 4.7 +/- 0.3%; P < 0.05). The mortality risk of calves aged 7-180 days was 6 (or 5.7) +/- 6.2% and increased with a shorter whole milk feeding period, longer period in the calving pen and lower average herd production level (P < 0.05). The mortality risk of calves was lower on farms where a veterinarian disbudded calves instead of farmer. Longer milk feeding and improved management of sick calves are recommended to reduce calf mortality. Specific management practices associated with lower mortality risk should be emphasised when advising farmers on how to enhance calf welfare. PMID- 27687947 TI - Corrigendum to 'Variance associated with use of relative velocity for force platform gait analysis in a heterogeneous population of clinically normal dogs' [The Veterinary Journal 207 (2016) 80-84]. PMID- 27687946 TI - Evaluation of different sampling methods and criteria for diagnosing canine urinary tract infection by quantitative bacterial culture. AB - The use of voided urine specimens for bacteriological culture in dogs is discouraged because contamination from external genitalia could lead to misinterpretation of laboratory results. Quantitative culturing and defining significant bacteriuria could increase the usefulness of voided specimens. However, limited evidence exists for the cut-offs currently recommended. The aim of this study was to evaluate the accuracy of current veterinary cut-off values for significant bacteriuria in voided canine urine. A secondary aim was to investigate if accuracy improved when applying qualitative criteria used in humans. Paired urine specimens were collected by both cystocentesis and voiding, and quantitative bacteriological cultures were performed within the same day. Cystocentesis was used as the reference standard with a cut-off for significant bacteriuria of >=1000 colony forming units (CFU)/mL. Voided specimens were compared to cystocentesis using: (1) the veterinary cut-off of >=100,000 CFU/mL; and (2) various cut-offs depending on qualitative criteria (sex, clinical signs and complicating factors), adapted from human guidelines. Ninety-four dogs with suspected urinary tract infection (UTI) were included for analysis. The veterinary cut-off yielded an accuracy of 94% with a sensitivity and specificity of 94% (95% confidence intervals [CI] 0.81, 0.99) and 94% (95% CI 0.86, 0.98), respectively. Applying the human guidelines did not improve overall accuracy (89%), and yielded a sensitivity and specificity of 97% (95% CI 0.86, 1.00) and 86% (95% CI 0.77, 0.92), respectively. The veterinary cut-off value of >=100,000 CFU/mL for voided urine is appropriate for determining significant bacteriuria in the majority of dogs with suspected UTI if specimens are refrigerated and cultured on the day of collection. PMID- 27687948 TI - Monitoring acute equine visceral pain with the Equine Utrecht University Scale for Composite Pain Assessment (EQUUS-COMPASS) and the Equine Utrecht University Scale for Facial Assessment of Pain (EQUUS-FAP): A validation study. AB - This study presents the validation of two recently described pain scales, the Equine Utrecht University Scale for Composite Pain Assessment (EQUUS-COMPASS) and the Equine Utrecht University Scale for Facial Assessment of Pain (EQUUS-FAP), in horses with acute colic. A follow-up cohort study of 46 adult horses (n = 23 with acute colic; n = 23 healthy control horses) was performed for validation and refinement of the constructed scales. Both pain scales showed statistically significant differences between horses with colic and healthy control horses, and between horses with colic that could be treated conservatively and those that required surgical treatment or were euthanased. Sensitivity and specificity were good for both EQUUS-COMPASS (87% and 71%, respectively) and EQUUS-FAP (77% and 100%, respectively) and were not substantially influenced by applying weighting factors to the individual parameters. PMID- 27687949 TI - Motor evoked potentials in standing and recumbent calves induced by magnetic stimulation at the foramen magnum. AB - The aims of this study were to determine reference values for magnetic motor evoked potentials (mMEPs) in calves and the influence of position during examination (standing or lateral recumbency). Reference values were determined using 41 healthy Holstein Friesian bull calves aged 1-10 months; standing and lateral recumbency were examined in 11 calves. Maximal magnetic stimulation was performed at the level of the foramen magnum with a magnetic field of 4 T at the coil surface. In standing position, distinct, reproducible mMEPs were obtained in all calves. Onset latency (LAT) (mean +/- standard deviation) was significantly shorter in the thoracic limbs (34.4 +/- 3.1 ms) than in the pelvic limbs (44.6 +/ 3.0 ms). Amplitude (AMPL) was significantly higher in the thoracic limbs (3.7 +/ 1.7 mV) than in the pelvic limbs (3.3 +/- 1.7 mV) and significantly increased with body length. Age, body weight, height at the withers and rectal temperature had no significant association with LAT or AMPL, and no differences between left and right were noted. In the lateral position, only 64% of the calves showed responses in the four limbs; in these calves, LAT (29.7 +/- 4.7 ms) and AMPL (3.0 +/- 1.8 mV) in the thoracic limbs were significantly different from AMPL (47.0 +/ 7.4 ms) and LAT (2.1 +/- 2.1 mV) in the pelvic limbs. In conclusion, mMEPs in limb muscles can be evoked in calves by stimulation at the level of the foramen magnum. mMEPs are more difficult to obtain in lateral recumbency than in standing calves. PMID- 27687950 TI - Isolation and characterisation of peripheral blood-derived feline mesenchymal stem cells. AB - The aim of this study was to isolate mesenchymal stem cells (MSCs) from feline peripheral blood (fPB-MSCs) and to characterise the cells' in vitro properties. The mononuclear cell fractions were isolated from venous blood of cats by density gradient centrifugation and cultured on plastic dishes under various culture conditions to isolate MSCs. When these cells were cultured with 5% autologous plasma (AP) and 10% foetal bovine serum (FBS), adherent spindle shaped fibroblast like cells (fPB-MSCs) were obtained from 15/22 (68%) cats. These cells were isolated only from medium containing both AP and FBS. The morphology of these MSCs was similar to those isolated from other species and from other feline tissues. fPB-MSCs expanded steadily up to 5-6 passages, but had increased population doubling time during passaging and almost all cells stopped proliferation at passages 7-9. These cells expressed CD44 and CD90, and were mostly negative for major histocompatibility class II and CD4. The cells could be induced to differentiate into adipogenic, osteogenic and chondrogenic cell lineages. These findings indicate that fPB-MSCs can be generated but appear to require specific culture conditions. PMID- 27687951 TI - Inter-observer agreement for clinical examinations of foot lesions of sheep. AB - In sheep, the diagnosis of foot lesions is routinely based on physical examination of the hoof. Correct diagnosis is important for the effective treatment, prevention and control of both infectious and non-infectious causes of lameness. Therefore, the aim of this study was to evaluate the level of inter observer agreement for clinical examination of ovine foot lesions. Eight observers of varying experience, training and occupation performed foot examinations on a total of 1158 sheep from 38 farms across North England and Wales. On each farm, a group of two to four observers independently examined a sample of 24 to 30 sheep to diagnose the presence or absence of specific foot lesions including white line lesions (WL), contagious ovine digital dermatitis (CODD), footrot (FR), inter-digital dermatitis (ID) and toe granuloma (TG). The inter-observer agreement of foot lesion assessments was examined using Fleiss kappa (kappa), and Cohen's kappa examined the paired agreement between the test standard observer (TSO) and each observer. Scoring differences with the TSO were examined as the percentage of scoring errors and assessed for evidence of systematic scoring bias. With the exception of WL (maximum error rate 33.3%), few scoring differences with the TSO occurred (maximum error rate 3.3%). This suggests that observers can achieve good levels of reliability when diagnosing most of the commonly observed foot conditions associated with lameness in sheep. PMID- 27687952 TI - Clinical, histopathological and metabolic responses following exercise in Arabian horses with a history of exertional rhabdomyolysis. AB - A previous report suggests a substantial incidence of exertional rhabdomyolysis (ER) in Arabian horses performing endurance racing. This study compared formalin histopathology and clinical and metabolic responses to a standardised field exercise test (SET) between Arabians with and without ER. Arabian horses with (n = 10; age 15.4 +/- 5.6 years) and without (n = 9; 12.9 +/- 6.1 years) prior ER were stall-rested for 24-48 h, after which paired ER and control horses were fitted with a telemetric ECG and performed a 47 min submaximal SET. Plasma glucose, lactate, electrolyte and total protein concentrations and packed cell volume were measured before and immediately after exercise. Blood and percutaneous gluteal muscle samples were also obtained before and 3 h after exercise for measurement of plasma creatine kinase (CK) activity and muscle glycogen concentration, respectively. Histopathologic analysis of formalin-fixed pre-exercise muscle sections was performed. Data were analyzed by ANOVA and non parametric tests (P <0.05). No horses displayed clinical signs of ER during exercise, and plasma CK increased similarly in ER and control Arabians. Muscle glycogen, heart rate, and remaining plasma variables did not differ between horses with ER and control horses. Horses with ER had more internalised nuclei in mature myofibers, more aggregates of cytoplasmic glycogen and desmin, and higher myopathic scores than control horses. Although many horses with ER had histopathologic evidence of chronic myopathy, muscle glycogen concentrations and metabolic exercise responses were normal. Results did not support a consistent metabolic myopathy or a glycogen storage disorder in Arabians with ER.

AB - Compressive hydrated nucleus pulposus extrusion (HNPE) in dogs is defined as acute extradural compression by hydrated nucleus pulposus material at the level of the associated intervertebral disc. Magnetic resonance imaging (MRI) is the imaging modality of choice for diagnosis of HNPE. The aims of this study were to determine the usefulness of unenhanced computed tomography (CT) and contrast enhanced CT (CE-CT), and the sensitivity and specificity of CE-CT, for detection of compressive HNPE. Using CE-CT, HNPE was visualised as a hypodense extradural compressive lesion with rim enhancement immediately dorsal to the intervertebral disc space, with a sensitivity of 91% and a specificity of 100%. CE-CT is a useful technique to detect compressive HNPE in dogs. However, if no clear lesion is identified with CE-CT, or if additional information about intramedullary changes is required, MRI still needs to be performed. PMID- 27687954 TI - Molecular epidemiology of senecavirus A associated with vesicular disease in pigs in Brazil. AB - Senecavirus A (SV-A) may cause vesicular disease and neonatal mortality in pigs, and was first detected in Brazil in 2015. Samples including tissues and serum from pigs with suspected vesicular diseases were collected from January to August in 2015 from farms in the states of Minas Gerais, Santa Catarina, Goias and Rio Grande do Sul, Brazil, and tested for the presence of SV-A by reverse transcriptase PCR. All samples were negative for foot and mouth disease virus, as well as 13 other infectious agents associated with vesicular diseases in pigs. SV A was detected by PCR in 65/265 (24.5%) specimens. A 530 base pair fragment sequenced from the VP1 protein coding region indicated a high genetic distance from SV-A in other countries, but a common origin among the Brazilian isolates. PMID- 27687956 TI - A novel slow-releasing hydrogen sulfide donor, FW1256, exerts anti-inflammatory effects in mouse macrophages and in vivo. AB - Exogenous hydrogen sulfide (H2S) is known to exert anti-inflammatory effects both in macrophages and in animal models. In this study, we first showed that NaHS caused a concentration dependent reduction in TNFalpha and IL-6 secretion in LPS stimulated RAW264.7 macrophages in the absence of cell death. Thereafter, we screened a series of novel slow H2S donors for similar activity. One such compound, FW1256, concentration dependently decreased TNFalpha, IL-6, PGE2 and NO generation in LPS-stimulated RAW264.7 macrophages and BMDMs. FW1256 also significantly reduced IL-1beta, COX-2 and iNOS mRNA and protein in LPS-stimulated RAW264.7 macrophages. Mechanistically, FW1256 decreased NFkappaB activation as evidenced by reduced cytosolic phospho-IkappaBalpha levels and reduced nuclear p65 levels in LPS-stimulated RAW264.7 macrophages treated with FW1256. Using a H2S fluorescent probe in FW1256-treated RAW264.7 macrophages, H2S release from FW1256 was apparent over a period of 24h in these cells. Moreover, the effect of FW1256 on TNFalpha and IL-6 by FW1256 in LPS-stimulated RAW264.7 macrophages was reversed by treatment with the H2S scavenger, vitamin B12a. FW1256 had no cytotoxic effect on LPS-stimulated RAW264.7 macrophages or BMDMs. In vivo, FW1256 administration also reduced IL-1beta, TNFalpha, nitrate/nitrite and PGE2 levels in LPS-treated mice. We show here a novel slow H2S-releasing compound that exerts anti-inflammatory effects in macrophages and in vivo. FW1256 may be a useful tool to study the biological effects of exogenous H2S and could also have future therapeutic value in inflammatory conditions. PMID- 27687955 TI - The thiirane-based selective MT1-MMP/MMP2 inhibitor ND-322 reduces melanoma tumor growth and delays metastatic dissemination. AB - MT1-MMP and MMP2 have been implicated as pro-tumorigenic and pro-metastatic factors in a wide variety of cancers including melanoma. We have previously demonstrated that MT1-MMP is highly expressed in melanoma where it promotes melanoma cell invasion and metastasis in part through the activation of its target MMP2. Given the accessibility of MMPs, as they are either secreted (e.g. MMP2) or membrane-tethered (e.g. MT1-MMP), they represent ideal targets for specific inhibition via small molecules. Here we show that the novel small molecule inhibitor ND-322 with high selectivity for MT1-MMP and MMP2, effectively inhibits MT1-MMP and MMP2 activity resulting in reduced in vitro melanoma cell growth, migration and invasion. Importantly, these inhibitory effects lead to significant reduction of melanoma tumor growth and metastasis. We further show that while cell migration and invasion could be similarly hampered by specific inhibition of either MT1-MMP or MMP2 via shRNAs, the growth inhibitory activity of ND-322 could only be mirrored by specific inhibition of MT1-MMP. These data support ND-322 as a novel effective inhibitor capable of counteracting both MT1 MMP and MMP2, two key proteases involved in melanoma growth and metastasis. ND 322 may therefore represent a new inhibitor in the repertoire of treatments against melanoma. PMID- 27687957 TI - Toll-like receptors and autophagy in interstitial lung diseases. AB - Interstitial lung diseases (ILDs) include a number of diseases whose pathogenesis still is not fully understood. Idiopathic pulmonary fibrosis (IPF), the most frequent and severe form of ILDs is an epithelial-driven disease and the treatment consists of the use of antifibrotic agents. In the rest of ILDs an inflammation-driven pathway is believed to be the main pathogenetic mechanism and treatment consists of the use of immunomodulatory agents. In both groups it is believed that infection can play an important role in the development and progression of the diseases. The immune system can recognize exogenous threats or endogenous stress through specialized receptors namely pattern recognition receptors (PRRs) which in turn, initiate downstream signaling pathways to control immune responses. Recently, a link between PRRs and autophagy, a specialized biological process involved in maintaining cellular homeostasis but also involved in various immunologic processes, has been described. In this review, we focus on the reciprocal influences of PRRs with particular emphasis on Toll-like receptors and autophagy in modulating innate immune responses. PMID- 27687958 TI - Treatment of diabetes: Crossing to the other side. AB - Type 2 diabetes mellitus affects nearly four hundred million people worldwide, and one of its major complications is cardiovascular disease. The evaluation of the effectiveness and safety of antidiabetic medication has been a challenging issue. Large clinical trials of new antidiabetic medications have used the non inferiority approach to ensure primary safety of the drug before its incorporation into clinical practice. Currently, the trend is to prove superiority, that is, to prove that the new drug has additional beneficial effects to those of standard medications. In this review, we present the results of recent clinical trials on type 2 diabetes mellitus medications and outline what can be anticipated from ongoing clinical trials. PMID- 27687959 TI - Effect of Irradiation on Queen Survivorship and Reproduction in the Invasive Fire Ant Solenopsis invicta (Hymenoptera: Formicidae) and a Proposed Phytosanitary Irradiation Treatment for Ants. AB - We studied radiation tolerance in queens of the red imported fire ant Solenopsis invicta Buren (Hymenoptera: Formicidae) to identify a dose that prevents reproduction. Virgin or fertile queens were collected from Santa Fe and Formosa provinces in Argentina and reared in the laboratory in microcolonies. Virgin queens were irradiated at 0 (control), 70, 90, 120, or 150 Gy, and fertile queens were irradiated at 0, 60, 125, and 190 Gy, and then followed for 11 wk in the microcolonies to evaluate survival and reproduction. Virgin queens lay trophic eggs that do not hatch, whereas fertile queens lay eggs that hatch and develop into brood. In general, queen oviposition and survival decreased with increasing irradiation dose. For virgin queens, no eggs were laid by irradiated queens after the third week, whereas the control queens continued laying eggs throughout the 11-wk experiment. For fertile queens, only one larva and no pupae was observed in the 60 Gy treatment and no larvae or pupae were observed in the 125 and 190 Gy treatments, whereas a total of 431 larvae and 83 pupae were produced by untreated control queens during 11 wks. Survivorship of virgin and fertile queens was similarly reduced by irradiation treatment. These results with S. invicta are consistent with previous findings for three other invasive ants, Wasmannia auropunctata (Roger), Pheidole megacephala (F.), and Linephithema humile (Mayr), that are hitchhiker pests on fresh horticultural commodities. A radiation dose of 150 Gy is proposed as a phytosanitary treatment to prevent reproduction in ants. PMID- 27687960 TI - Educating patients in IBD. PMID- 27687961 TI - Assessment of vitreous haze using ultra-wide field retinal imaging. AB - BACKGROUND: Conventional fundus imaging has been used to assess vitreous haze (VH) in patients with uveitis. Ultra-wide field (UWF) retinal imaging that uses scanning laser technology has not been evaluated for the detection of VH. This pilot study evaluates the ability of UWF imaging in detecting VH. Patients with intermediate, posterior, or panuveitis were examined to assess the level of VH using slit-lamp biomicroscopy. Colored fundus images were acquired using a Carl Zeiss FF450 camera. The same photographer obtained fundus images of the same eyes during the same visit by Optos UWF P200Tx retinal camera. Two graders independently analyzed UWF fundus images for presence or absence of VH, without quantifying the degree of VH using any scale. The images were analyzed using the composite red plus red-free wavelengths utilized by the Optos UWF camera and by using each wavelength exclusively. These findings were compared to clinical detection of VH and detection of VH using conventional fundus photography. RESULTS: Ninety-two eyes were included in the study. For composite UWF images, sensitivity was 0.27, specificity was 0.88, PPV was 0.31, NPV was 0.86, positive LR was 2.25, and negative LR was 0.83. For the conventional Zeiss images, sensitivity was 0.5, specificity was 0.84, PPV was 0.33, NPV was 0.91, positive LR was 3.13, and negative LR was 0.6. Agreement between the composite UWF and Zeiss techniques was substantial with k = 0.64. Inter-observer agreement for composite UWF images was also substantial with k = 0.65. Inter-observer agreement for Zeiss images was moderate with k = 0.471. Intra-observer agreement for both imaging modalities was substantial with a composite UWF k = 0.76 and Zeiss k = 0.7. CONCLUSIONS: UWF fundus imaging using scanning laser technique may be used to assess VH and employed in the management of intermediate, posterior, and panuveitis. PMID- 27687962 TI - The IASLC Mesothelioma Staging Project: Proposals for the M Descriptors and for Revision of the TNM Stage Groupings in the Forthcoming (Eighth) Edition of the TNM Classification for Mesothelioma. AB - INTRODUCTION: The M component and TNM stage groupings for malignant pleural mesothelioma (MPM) have been empirical. The International Association for the Study of Lung Cancer developed a multinational database to propose evidence-based revisions for the eighth edition of the TNM classification of MPM. METHODS: Data from 29 centers were submitted either electronically or by transfer of existing institutional databases. The M component as it currently stands was validated by confirming sufficient discrimination (by Kaplan-Meier analysis) with respect to overall survival (OS) between the clinical M0 (cM0) and cM1 categories. Candidate stage groups were developed by using a recursive partitioning and amalgamation algorithm applied to all cM0 cases. RESULTS: Of 3519 submitted cases, 2414 were analyzable and 84 were cM1 cases. Median OS for cM1 cases was 9.7 months versus 13.4 months (p = 0.0013) for the locally advanced (T4 or N3) cM0 cases, supporting inclusion of only cM1 in the stage IV group. Exploratory analyses suggest a possible difference in OS for single- versus multiple-site cM1 cases. A recursive partitioning and amalgamation-generated survival tree on the OS outcomes restricted to cM0 cases with the newly proposed (eighth edition) T and N components indicates that optimal stage groupings for the eighth edition will be as follows: stage IA (T1N0), stage IB (T2-3N0), stage II (T1-2N1), stage IIIA (T3N1), stage IIIB (T1-3N2 or any T4), and stage IV (any M1). CONCLUSIONS: This first evidence-based revision of the TNM classification for MPM leads to substantial changes in the T and N components and the stage groupings. PMID- 27687966 TI - Shear Modulus of the Partially Obstructed Rat Small Intestine. AB - A number of factors influence gastrointestinal tissue structure and mechanical properties such as the physical environment and diseases like partial obstruction. Hence multi-axial biomechanical properties are important for understanding the pathophysiology of the obstructed intestine. The aim was to estimate the multi-axial biomechanical properties, in particular with focus on the shear modulus. Partial obstruction of mid-jejunum was created surgically by placement of a polyethylene ring for two weeks in seven male rats. Sham operation was made in five other rats. At the time for termination, three 6-cm intestinal segments were used for histological and mechanical analysis. The segments were obtained distal (S1), proximal (S2) and further proximal (S3) to the site of obstruction or suturing site. The tri-axial testing included simultaneous torsion, inflation and longitudinal stretching. The lumen size, wall thickness, wall cross-sectional area, and muscle layer thickness increased in S2 and S3 of the obstructed rats (p < 0.001) with the most pronounced changes in S2. The opening angle decreased in S2 in the obstructed group (p < 0.05). The tissue stiffness increased in circumferential and longitudinal direction where as it was softer in shear direction, especially in S2 (p < 0.01). In conclusion, the histomorphological and mechanical properties including shear properties remodeled proximal to the intestinal obstruction site. PMID- 27687963 TI - The IASLC Mesothelioma Staging Project: Proposals for Revisions of the T Descriptors in the Forthcoming Eighth Edition of the TNM Classification for Pleural Mesothelioma. AB - INTRODUCTION: The current T component for malignant pleural mesothelioma (MPM) has been predominantly informed by surgical data sets and consensus. The International Association for the Study of Lung Cancer undertook revision of the seventh edition of the staging system for MPM with the goal of developing recommendations for the eighth edition. METHODS: Data elements including detailed T descriptors were developed by consensus. Tumor thickness at three pleural levels was also recorded. An electronic data capture system was established to facilitate data submission. RESULTS: A total of 3519 cases were submitted to the database. Of those eligible for T-component analysis, 509 cases had only clinical staging, 836 cases had only surgical staging, and 642 cases had both available. Survival was examined for T categories according to the current seventh edition staging system. There was clear separation between all clinically staged categories except T1a versus T1b (hazard ratio = 0.99, p = 0.95) and T3 versus T4 (hazard ratio = 1.22, p = 0.09), although the numbers of T4 cases were small. Pathological staging failed to demonstrate a survival difference between adjacent categories with the exception of T3 versus T4. Performance improved with collapse of T1a and T1b into a single T1 category; no current descriptors were shifted or eliminated. Tumor thickness and nodular or rindlike morphology were significantly associated with survival. CONCLUSIONS: A recommendation to collapse both clinical and pathological T1a and T1b into a T1 classification will be made for the eighth edition staging system. Simple measurement of pleural thickness has prognostic significance and should be examined further with a view to incorporation into future staging. PMID- 27687965 TI - Web-Based Intervention to Reduce Substance Abuse and Depressive Symptoms in Mexico: Development and Usability Test. AB - BACKGROUND: The development of Web-based interventions for substance abuse in Latin America is a new field of interest with great potential for expansion to other Spanish-speaking countries. OBJECTIVE: This paper describes a project aimed to develop and evaluate the usability of the Web-based Help Program for Drug Abuse and Depression (Programa de Ayuda para Abuso de Drogas y Depresion, PAADD, in Spanish) and also to construct a systematic frame of reference for the development of future Web-based programs. METHODS: The PAADD aims to reduce substance use and depressive symptoms with cognitive behavioral techniques translated into Web applications, aided by the participation of a counselor to provide support and guidance. This Web-based intervention includes 4 steps: (1) My Starting Point, (2) Where Do I Want to Be? (3) Strategies for Change, and (4) Maintaining Change. The development of the program was an interactive multistage process. The first stage defined the core structure and contents, which were validated in stage 2 by a group of 8 experts in addiction treatment. Programming of the applications took place in stage 3, taking into account 3 types of end users: administrators, counselors, and substance users. Stage 4 consisted of functionality testing. In stage 5, a total of 9 health professionals and 20 drug users currently in treatment voluntarily interacted with the program in a usability test, providing feedback about adjustments needed to improve users' experience. RESULTS: The main finding of stage 2 was the consensus of the health professionals about the cognitive behavioral strategies and techniques included in PAADD being appropriate for changing substance use behaviors. In stage 5, the health professionals found the functionalities easy to learn; their suggestions were related to the page layout, inclusion of confirmation messages at the end of activities, avoiding "read more" links, and providing feedback about every activity. On the other hand, the users said the information presented within the modules was easy to follow and suggested more dynamic features with concrete instructions and feedback. CONCLUSIONS: The resulting Web-based program may have advantages over traditional face-to-face therapies owing to its low cost, wide accessibility, anonymity, and independence of time and distance factors. The detailed description of the process of designing a Web-based program is an important contribution to others interested in this field. The potential benefits must be verified in specific studies.

PMID- 27687964 TI - The IASLC Mesothelioma Staging Project: Proposals for Revisions of the N Descriptors in the Forthcoming Eighth Edition of the TNM Classification for Pleural Mesothelioma. AB - INTRODUCTION: Nodal categories for malignant pleural mesothelioma are derived from the lung cancer staging system and have not been adequately validated. The International Association for the Study of Lung Cancer developed a multinational database to generate evidence-based recommendations to inform the eighth edition of the TNM classification of malignant pleural mesothelioma. METHODS: Data from 29 centers were entered prospectively (n = 1566) or by transfer of retrospective data (n = 1953). Survival according to the seventh edition N categories was evaluated using Kaplan-Meier survival curves and Cox proportional hazards regression analysis. Survival was measured from the date of diagnosis. RESULTS: There were 2432 analyzable cases: 1603 had clinical (c) staging, 1614 had pathologic (p) staging, and 785 had both. For clinically staged tumors there was no separation in Kaplan-Meier curves between cN0, cN1 or cN2 (cN1 versus cN0 hazard ratio [HR] = 1.06, p = 0.77 and cN2 versus cN1 HR = 1.04, p = 0.85). For pathologically staged tumors, patients with pN1 or pN2 tumors had worse survival than those with pN0 tumors (HR = 1.51, p < 0.0001) but no survival difference was noted between those with pN1 and pN2 tumors (HR = 0.99, p = 0.99). Patients with both pN1 and pN2 nodal involvement had poorer survival than those with pN2 tumors only (HR = 1.60, p = 0.007) or pN0 tumors (HR = 1.62, p < 0.0001). CONCLUSIONS: A recommendation to collapse both clinical and pN1 and pN2 categories into a single N category comprising ipsilateral, intrathoracic nodal metastases (N1) will be made for the eighth edition staging system. Nodes previously categorized as N3 will be reclassified as N2. PMID- 27687967 TI - Structure-based design of a new series of N-(piperidin-3-yl)pyrimidine-5 carboxamides as renin inhibitors. AB - The action of the aspartyl protease renin is the rate-limiting initial step of the renin-angiotensin-aldosterone system. Therefore, renin is a particularly promising target for blood pressure as well as onset and progression of cardiovascular and renal diseases. New pyrimidine derivatives 5-14 were designed in an attempt to enhance the renin inhibitory activity of compound 3 identified by our previous fragment-based drug design approach. Introduction of a basic amine essential for interaction with the two aspartic acids in the catalytic site and optimization of the S1/S3 binding elements including an induced-fit structural change of Leu114 ('Leu-in' to 'Leu-out') by a rational structure-based drug design approach led to the discovery of N-(piperidin-3-yl)pyrimidine-5 carboxamide 14, a 65,000-fold more potent renin inhibitor than compound 3. Surprisingly, this remarkable enhancement in the inhibitory activity of compound 14 has been achieved by the overall addition of only seven heavy atoms to compound 3. Compound 14 demonstrated excellent selectivity over other aspartyl proteases and moderate oral bioavailability in rats.

AB - A facile stereoselective synthesis of novel dispiro indeno pyrrolidine/pyrrolothiazole-thiochroman hybrids has been achieved by 1,3-dipolar cycloaddition of azomethine ylides, generated in situ from ninhydrin and sarcosine/thiaproline, on a series of 3-benzylidenethiochroman-4-ones. The synthesised compounds were screened for their antimycobacterial, anticancer and AchE inhibition activities. Compound 4l (IC50 1.07MUM) has been found to exhibit the most potent antimycobacterial activity compared to cycloserine (12 times), pyrimethamine (37 times) and ethambutol (IC50 <1.56MUM) and 6l (IC50=2.87MUM) is more active than both cycloserine (4 times) and pyrimethamine (12 times). Three compounds, 4a, 6b and 6i, display good anticancer activity against CCRF-CEM cell lines. Compounds 6g and 4g display maximum AchE inhibitory activity with IC50 values of 1.10 and 1.16MUmol/L respectively. PMID- 27687969 TI - Design, synthesis and biological evaluation of potential antibacterial butyrolactones. AB - Novel butyrolactone analogues were designed and synthesized based on the known lichen antibacterial compounds, lichesterinic acids (B-10 and B-11), by substituting different functional groups on the butyrolactone ring trying to enhance its activity. All synthesized butyrolactone analogues were evaluated for their in vitro antibacterial activity against Streptococcus gordonii. Among the derivatives, B-12 and B-13 had the lowest MIC of 9.38MUg/mL where they have shown to be stronger bactericidals, by 2-3 times, than the reference antibiotic, doxycycline. These two compounds were then checked for their cytotoxicity against human gingival epithelial cell lines, Ca9-22, and macrophages, THP-1, by MTT and LDH assays which confirmed their safety against the tested cell lines. A preliminary study of the structure-activity relationships unveiled that the functional groups at the C4 position had an important influence on the antibacterial activity. An optimum length of the alkyl chain at the C5 position registered the best antibacterial inhibitory activity however as its length increased the bactericidal effect increased as well. This efficiency was attained by a carboxyl group substitution at the C4 position indicating the important dual role contributed by these two substituents which might be involved in their mechanism of action. PMID- 27687970 TI - Design, synthesis and evaluation of anti-CD123 antibody drug conjugates. AB - Leukemia stem cells (LSCs) account for the development of drug resistance and increased recurrence rate in acute myeloid leukemia (AML) patients. Targeted drug delivery to leukemia stem cells remains a major challenge in AML chemotherapy. Overexpressed interleukin-3 receptor alpha chain, CD123, on the surface of leukemia stem cells was reported to be a potential target in AML treatment. Here, we designed and developed an antibody drug conjugate (CD123-CPT) by integrating anti-CD123 antibody with a chemotherapeutic agent, Camptothecin (CPT), via a disulfide linker. The linker is biodegradable in the presence of Glutathione (GSH, an endogenous component in cells), which leads to release of CPT. Anti CD123 antibody conjugates showed significant higher cellular uptake in CD123 overexpressed tumor cells. More importantly, CD123-CPT demonstrated potent inhibitory effects on CD123-overexpressed tumor cells. Consequently, these results provide a promising targeted chemotherapeutical strategy for AML treatment. PMID- 27687971 TI - Tyrosyl-DNA phosphodiesterase inhibitors: Progress and potential. AB - DNA topoisomerases are essential during transcription and replication. The therapeutic mechanism of action of topoisomerase inhibitors is enzyme poisoning rather than catalytic inhibition. Tyrosyl-DNA phosphodiesterases 1 or 2 were found as DNA repair enzymes hydrolyzing the covalent bond between the tyrosyl residue of topoisomerases I or II and the 3'- or 5'-phosphate groups in DNA, respectively. Tyrosyl-DNA phosphodiesterase 1 is a key enzyme in DNA repair machinery and a promising target for antitumor and neurodegenerative therapy. Inhibitors of tyrosyl-DNA phosphodiesterase 1 could act synergistically with topoisomerase I inhibitors and thereby potentiate the effects of topoisomerase I poisons. Tyrosyl-DNA phosphodiesterase 2 is an enzyme that specifically repairs DNA damages induced by topoisomerase II poisons and causes resistance to these drugs. Selective inhibition of tyrosyl-DNA phosphodiesterase 2 may be a novel approach to overcome intrinsic or acquired resistance to topoisomerase II targeted drug therapy. Thus, agents that inhibit tyrosyl-DNA phosphodiesterases 1 and 2 have many applications in biochemical and physiological research and they have the potential to become anticancer and antiviral drugs. The structures, mechanism of action and therapeutic rationale of tyrosyl-DNA phosphodiesterase inhibitors and their development for combinations with topoisomerase inhibitors and DNA damaging agents are discussed. PMID- 27687973 TI - Measuring time utilization of pharmacists in the Birmingham Free Clinic dispensary. AB - BACKGROUND: Free and charitable clinics are a critical part of America's healthcare safety net. Although informatics tools have the potential to mitigate many of the organizational and service-related challenges facing these clinics, little research attention has been paid to the workflows and potential impact of electronic systems in these settings. In previous work, we performed a qualitative investigation at a free clinic dispensary to identify workflow challenges that may be alleviated through introduction of informatics interventions. However, this earlier study did not quantify the magnitude of these challenges. Time-motion studies offer a precise standard in quantifying healthcare workers' time expenditures on clinical activities, and can provide valuable insight into system specifications. These data, informed by a lean healthcare perspective, provide a quality improvement framework intended to maximize value and eliminate waste in inefficient workflow processes. METHODS: We performed a continuous observation time-motion study in the Birmingham Free Clinic dispensary. Two researchers followed pharmacists over the course of three general clinic sessions and recorded the duration of specific tasks. Pharmacists were then asked to identify tasks as value-added or non-value-added to facilitate calculation of the value quotient, a metric used to determine a workflow's level of efficiency. RESULTS: Four high-level workflow categories occupied almost 95 % of pharmacist time: prescription (Rx) preparation (39.8 %), clinician interaction (21.5 %), EMR operations (14.8 %), and patient interaction (18.7 %). Pharmacists invested the largest portion of time in prescription preparation, with 21.8 % of pharmacist time spent handwriting medication labels. Based on value categorizations made by the pharmacists, the average value quotient was found to be 40.3 %, indicating that pharmacists spend more than half of their time completing tasks they consider to be non-value-added. CONCLUSIONS: Our results show that pharmacists spend a large portion of their time preparing prescriptions, primarily the handwritten labeling of medication bottles and documentation tasks, which is not an optimal utilization of pharmacist expertise. The value quotient further supports that there are many wasteful tasks that may benefit from workflow redesign and health information technology, which could result in efficiency improvements for pharmacists. PMID- 27687972 TI - Deep brain stimulation of the posterior subthalamic area and the thalamus in patients with essential tremor: study protocol for a randomized controlled pilot trial. AB - BACKGROUND: Deep brain stimulation (DBS) of the ventral intermediate nucleus (VIM) of the thalamus is effective in medication refractory essential tremor (ET). In recent years, evidence has accumulated that the region ventral to the VIM, the posterior subthalamic area (PSA), might be an equally or even more effective target for electrode implantation. However, this evidence is primarily based on case series, cross-sectional observations, and retrospective data. METHODS/DESIGN: A prospective crossover pilot study investigating the effects of PSA stimulation in medication refractory ET patients was designed. In this study, bilateral electrodes are implanted such that at least one of the electrode contacts is located in the PSA and VIM, respectively. This implantation approach allows (1) a prospective double-blind investigation of the effects of PSA stimulation compared to baseline, as well as (2) a crossover comparison between VIM and PSA stimulation with respect to tremor suppression and side effect profiles. DISCUSSION: The results of this double-blinded, prospective study will allow a better understanding of the effects and side effects of PSA compared to VIM-DBS in patients with ET.

AB - SAR11 is a group of small, carbon-oxidizing bacteria that reach a global estimated population size of 2.4*1028 cells-approximately 25% of all plankton. They are found throughout the oceans but reach their largest numbers in stratified, oligotrophic gyres, which are an expanding habitat in the warming oceans. SAR11 likely had a Precambrian origin and, over geological time, evolved into the niche of harvesting labile, low-molecular-weight dissolved organic matter (DOM). SAR11 cells are minimal in size and complexity, a phenomenon known as streamlining that is thought to benefit them by lowering the material costs of replication and maximizing transport functions that are essential to competition at ultralow nutrient concentrations. One of the surprises in SAR11 metabolism is their ability to both oxidize and produce a variety of volatile organic compounds that can diffuse into the atmosphere. SAR11 cells divide slowly and lack many forms of regulation commonly used by bacterial cells to adjust to changing environmental conditions. As a result of genome reduction, they require an unusual range of nutrients, which leads to complex biochemical interactions with other plankton. The study of SAR11 is providing insight into the biogeochemistry of labile DOM and is affecting microbiology beyond marine science by providing a model for understanding the evolution and function of streamlined cells.

However, up to now, investigations of the phase selection in HEAs mainly focused on the thermodynamic equilibrium phase, while kinetic ways of tailoring the phases in HEAs are seldom considered. In HEAs, the kinetics of sluggish diffusion and the numerous possible phases make the kinetics of phase transformation more complex and intriguing. Here, the kinetic effect in CoCrFeNiTi0.4 HEAs was investigated to reveal the possibility of controlling phase selection via kinetic ways for HEAs. The sigma, gamma' and R phases in the CoCrFeNiTi0.4 HEA can be controlled under different cooling rate both in solidification and solid transformation. The theoretical analyses revealed the kinetic effect on phase selection. The method proposed here, tailoring the phases with different kinetic ways, could be used to prepare promising HEAs with very rich composition design.

AB - Cilia are cell surface organelles with key roles in a range of cellular processes, including generation of fluid flow by motile cilia. The axonemes of motile cilia and immotile kinocilia contain 9 peripheral microtubule doublets, a central microtubule pair, and 9 connecting radial spokes. Aberrant radial spoke components RSPH1, 3, 4a and 9 have been linked with primary ciliary dyskinesia (PCD), a disorder characterized by ciliary dysmotility; yet, radial spoke functions remain unclear. Here we show that zebrafish Rsph9 is expressed in cells bearing motile cilia and kinocilia, and localizes to both 9 + 2 and 9 + 0 ciliary axonemes. Using CRISPR mutagenesis, we show that rsph9 is required for motility of presumptive 9 + 2 olfactory cilia and, unexpectedly, 9 + 0 neural cilia. rsph9 is also required for the structural integrity of 9 + 2 and 9 + 0 ciliary axonemes. rsph9 mutant larvae exhibit reduced initiation of the acoustic startle response consistent with hearing impairment, suggesting a novel role for Rsph9 in the kinocilia of the inner ear and/or lateral line neuromasts. These data identify novel roles for Rsph9 in 9 + 0 motile cilia and in sensory kinocilia, and establish a useful zebrafish PCD model. PMID- 27687977 TI - Dysbiosis of small intestinal microbiota in liver cirrhosis and its association with etiology. AB - Cirrhosis-associated duodenal dysbiosis is not yet clearly defined. In this research, duodenal mucosal microbiota was analyzed in 30 cirrhotic patients and 28 healthy controls using 16S rRNA gene pyrosequencing methods. The principal coordinate analysis revealed that cirrhotic patients were colonized by remarkable different duodenal mucosal microbiota in comparison with controls. At the genus level, Veillonella, Megasphaera, Dialister, Atopobium, and Prevotella were found overrepresented in cirrhotic duodenum. And the duodenal microbiota of healthy controls was enriched with Neisseria, Haemophilus, and SR1 genera incertae sedis. On the other hand, based on predicted metagenomes analyzed, gene pathways related to nutrient absorption (e.g. sugar and amino acid metabolism) were highly abundant in cirrhosis duodenal microbiota, and functional modules involved in bacterial proliferation and colonization (e.g. bacterial motility proteins and secretion system) were overrepresented in controls. When considering the etiology of cirrhosis, two operational taxonomic units (OTUs), OTU-23 (Neisseria) and OTU 36 (Gemella), were found discriminative between hepatitis-B-virus related cirrhosis and primary biliary cirrhosis. The results suggest that the structure of duodenal mucosa microbiota in cirrhotic patients is dramatically different from healthy controls. The duodenum dysbiosis might be related to alterations of oral microbiota and changes in duodenal micro-environment. PMID- 27687978 TI - Radon versus other lung cancer risk factors: How accurate are the attribution estimates? AB - : This notebook paper provides a brief overview of attribution estimates for some key lung cancer risk factors, focusing on indoor radon gas exposure in the U.S., UK, and Canada. Tobacco smoking represents the primary cause of lung cancer worldwide. Radon is regarded as the second leading lung cancer risk factor in the U.S. and Canada. It can be observed, however, that the reported estimates appear not to add up to the maximum cumulative attribution of 100%. IMPLICATIONS: Limitations and uncertainties associated with published epidemiological studies and the observed lack of consistency in lung cancer attribution estimates for radon and other non-smoking lung cancer risk factors should be taken into consideration by policy makers in setting population health protection priorities.

AB - Fundamental cancer research and the development of efficacious antineoplastic treatments both rely on experimental systems in which the relationship between malignant cells and immune cells can be studied. Mouse models of transplantable, carcinogen-induced or genetically engineered malignancies - each with their specific advantages and difficulties - have laid the foundations of oncoimmunology. These models have guided the immunosurveillance theory that postulates that evasion from immune control is an essential feature of cancer, the concept that the long-term effects of conventional cancer treatments mostly rely on the reinstatement of anticancer immune responses and the preclinical development of immunotherapies, including currently approved immune checkpoint blockers. Specific aspects of pharmacological development, as well as attempts to personalize cancer treatments using patient-derived xenografts, require the development of mouse models in which murine genes and cells are replaced with their human equivalents. Such 'humanized' mouse models are being progressively refined to characterize the leukocyte subpopulations that belong to the innate and acquired arms of the immune system as they infiltrate human cancers that are subjected to experimental therapies. We surmise that the ever-advancing refinement of murine preclinical models will accelerate the pace of therapeutic optimization in patients. PMID- 27687983 TI - Wnt/beta-catenin signaling pathway activation is required for proliferation of chicken primordial germ cells in vitro. AB - Here, we investigated the role of the Wnt/beta-catenin signaling pathway in chicken primordial germ cells (PGCs) in vitro. We confirmed the expression of Wnt signaling pathway-related genes and the localization of beta-catenin in the nucleus, revealing that this pathway is potentially activated in chicken PGCs. Then, using the single-cell pick-up assay, we examined the proliferative capacity of cultured PGCs in response to Wnt ligands, a beta-catenin-mediated Wnt signaling activator (6-bromoindirubin-3'-oxime [BIO]) or inhibitor (JW74), in the presence or absence of basic fibroblast growth factor (bFGF). WNT1, WNT3A, and BIO promoted the proliferation of chicken PGCs similarly to bFGF, whereas JW74 inhibited this proliferation. Meanwhile, such treatments in combination with bFGF did not show a synergistic effect. bFGF treatment could not rescue PGC proliferation in the presence of JW74. In addition, we confirmed the translocation of beta-catenin into the nucleus by the addition of bFGF after JW74 treatment. These results indicate that there is signaling crosstalk between FGF and Wnt, and that beta-catenin acts on PGC proliferation downstream of bFGF. In conclusion, our study suggests that Wnt signaling enhances the proliferation of chicken PGCs via the stabilization of beta-catenin and activation of its downstream genes. PMID- 27687985 TI - A Critique of Henrik Friberg-Fernros's Defense of the Substance View. AB - Proponents of the substance view contend that abortion is seriously morally wrong because it is killing something with the same inherent value and right to life as you or I. Rob Lovering offers two innovative criticisms of the anti-abortion position taken by the substance view - the rescue argument and the problem of spontaneous abortion. Henrik Friberg-Fernros offers an interesting response to Lovering, but one I argue would be inconsistent with the anti-abortion stance taken by most substance view theorists. PMID- 27687984 TI - MITK-OpenIGTLink for combining open-source toolkits in real-time computer assisted interventions. AB - PURPOSE: Due to rapid developments in the research areas of medical imaging, medical image processing and robotics, computer-assisted interventions (CAI) are becoming an integral part of modern patient care. From a software engineering point of view, these systems are highly complex and research can benefit greatly from reusing software components. This is supported by a number of open-source toolkits for medical imaging and CAI such as the medical imaging interaction toolkit (MITK), the public software library for ultrasound imaging research (PLUS) and 3D Slicer. An independent inter-toolkit communication such as the open image-guided therapy link (OpenIGTLink) can be used to combine the advantages of these toolkits and enable an easier realization of a clinical CAI workflow. METHODS: MITK-OpenIGTLink is presented as a network interface within MITK that allows easy to use, asynchronous two-way messaging between MITK and clinical devices or other toolkits. Performance and interoperability tests with MITK OpenIGTLink were carried out considering the whole CAI workflow from data acquisition over processing to visualization. RESULTS: We present how MITK OpenIGTLink can be applied in different usage scenarios. In performance tests, tracking data were transmitted with a frame rate of up to 1000 Hz and a latency of 2.81 ms. Transmission of images with typical ultrasound (US) and greyscale high-definition (HD) resolutions of [Formula: see text] and [Formula: see text] is possible at up to 512 and 128 Hz, respectively. CONCLUSION: With the integration of OpenIGTLink into MITK, this protocol is now supported by all established open-source toolkits in the field. This eases interoperability between MITK and toolkits such as PLUS or 3D Slicer and facilitates cross-toolkit research collaborations. MITK and its submodule MITK-OpenIGTLink are provided open source under a BSD-style licence ( http://mitk.org ). PMID- 27687986 TI - The Google matrix controls the stability of structured ecological and biological networks. AB - May's celebrated theoretical work of the 70's contradicted the established paradigm by demonstrating that complexity leads to instability in biological systems. Here May's random-matrix modelling approach is generalized to realistic large-scale webs of species interactions, be they structured by networks of competition, mutualism or both. Simple relationships are found to govern these otherwise intractable models, and control the parameter ranges for which biological systems are stable and feasible. Our analysis of model and real empirical networks is only achievable on introducing a simplifying Google-matrix reduction scheme, which in the process, yields a practical ecological eigenvalue stability index. These results provide an insight into how network topology, especially connectance, influences species stable coexistence. Constraints controlling feasibility (positive equilibrium populations) in these systems are found more restrictive than those controlling stability, helping explain the enigma of why many classes of feasible ecological models are nearly always stable. PMID- 27687982 TI - Epstein-Barr virus: more than 50 years old and still providing surprises. AB - It is more than 50 years since the Epstein-Barr virus (EBV), the first human tumour virus, was discovered. EBV has subsequently been found to be associated with a diverse range of tumours of both lymphoid and epithelial origin. Progress in the molecular analysis of EBV has revealed fundamental mechanisms of more general relevance to the oncogenic process. This Timeline article highlights key milestones in the 50-year history of EBV and discusses how this virus provides a paradigm for exploiting insights at the molecular level in the diagnosis, treatment and prevention of cancer. PMID- 27687987 TI - Discontinuation of long-term adalimumab treatment in patients with juvenile idiopathic arthritis-associated uveitis. AB - PURPOSE: The purpose of this study was to evaluate the discontinuation of adalimumab (ADA) treatment in patients with juvenile idiopathic arthritis associated uveitis (JIAU). METHODS: Patients in whom ADA treatment was initiated for JIAU were included in this retrospective analysis. Reasons for discontinuing ADA treatment in patients with primary treatment response were analysed. RESULTS: Within a group of 387 JIAU patients, 59 of 68 patients who were treated with ADA achieved a sufficient response to treatment within 6 months. Here, 39 patients (66.1 %) were still on therapy at their last follow-up visit (mean treatment duration of 38.3 months, range 12-91). In another 20 patients, ADA had been discontinued after 1 or 2 years or later, in 10 % (n = 2), 45 % (n = 9) and 45 % (n = 9) of patients, respectively (mean 30.6 months; range 10-65). Reasons for discontinuing ADA were reactivation of uveitis (n = 8, 3.93 per 100 patient years) or arthritis (n = 4; 1.97 per 100 patient-years), or >=2 years of complete disease inactivity (n = 3, 1.47 per 100 patient-years), adverse events (n = 4; 1.89 per 100 patient-years), or other (n = 1; 0.47 per 100 patient-years). CONCLUSIONS: The data show a good primary response to ADA in patients with refractory JIAU. Due to the increasing rate of adalimumab failure or adverse events during long-term treatment, further treatment options may be required. PMID- 27687989 TI - Maternal Body Mass Index and Risk of Autism Spectrum Disorders in Offspring: A Meta-analysis. AB - Controversial results of the association between maternal body mass index (BMI) and risk of autism spectrum disorder (ASD) in offspring were reported among several studies. This meta-analysis was conducted to estimate the overall association between maternal BMI and risk of ASD in offspring. PubMed, EMBASE, Web of Science, and the Cochrane Library were searched until January 2016. Cohort and case-control studies addressing the association between maternal BMI and risk of ASD in offspring were included. We used random-effect models to estimate the summary relative risks (RRs), we also performed a dose-response meta-analysis to estimate the trend from the correlated log RR estimates across levels of BMI quantitatively. Totally, 6 cohort studies and 1 case-control study involving 8,403 cases and 509,167 participants were included for analysis. The summary RR (95% confidence interval) for ASD in offspring in relation to maternal underweight, overweight, and obesity vs. normal weight during pre-pregnancy or pregnancy, was 1.07 (0.93, 1.23), 1.28 (1.19, 1.36) and 1.36 (1.03, 1.78), respectively. A linear dose-response relationship was found, with a pooled RR of 1.16 (1.01, 1.33) for each 5 kg/m2. increment in maternal BMI. The present study suggests that excessive maternal BMI is associated with increased ASD risk in offspring. PMID- 27687988 TI - One-year outcome of combination therapy with intravitreal aflibercept and verteporfin photodynamic therapy for polypoidal choroidal vasculopathy. AB - PURPOSE: The purpose of the study was to evaluate the 1-year visual and anatomical outcomes of combination therapy with intravitreal aflibercept (IVA) and verteporfin photodynamic therapy (vPDT) for polypoidal choroidal vasculopathy (PCV), and to determine the predictors of a good visual outcome. METHODS: This was a prospective case-series study. Twenty eyes from 20 treatment-naive PCV patients were treated with combination therapy with IVA and vPDT. Best-corrected visual acuity (BCVA) and morphological parameters including polypoidal lesions in indocyanine green angiography (ICGA) were evaluated over 12 months of follow-up. RESULTS: The mean logMAR BCVA was significantly improved from 0.30 at baseline to 0.20 at 3 months and 0.18 at 12 months. The mean central retinal thickness was also significantly improved at 3 months and at 12 months. In ICGA, complete regression of polypoidal lesions was found in 14 out of 20 eyes (70 %) at 3 months and in 14 out of 18 eyes (78 %) at 12 months although no ICGA were done on two eyes. In the multivariate logistic regression analyses, the baseline greatest linear dimension was found as a significant predictive factor for good visual improvement (?0.3 LogMAR units improvement from baseline) at 12 months. CONCLUSION: In this study, combination therapy with IVA and vPDT gave visual and anatomical improvements to treatment-naive PCV patients over 12 months of follow up period. PMID- 27687990 TI - Reevaluating multicolor flow cytometry to assess microbial viability. AB - Flow cytometry is a rapid and quantitative method to determine bacterial viability. Although different stains can be used to establish viability, staining protocols are inconsistent and lack a general optimization approach. Very few "true" multicolor protocols, where dyes are combined in one sample, have been developed for microbiological applications. In this mini-review, the discrepancy between protocols for cell-permeant nucleic acid and functional stains are discussed as well as their use as viability dyes. Furthermore, optimization of staining protocols for a specific setup are described. Original data using the red-excitable SYTO dyes SYTO 59 to 64 and SYTO 17, combined with functional stains, for double and triple staining applications is also included. As each dye and dye combination behaves differently within a certain combination of medium matrix, microorganism, and instrument, protocols need to be tuned to obtain reproducible results. Therefore, single, double, and triple stains are reviewed, including the different parameters that influence staining such as stain kinetics, optimal stain concentration, and the effect of the chelator EDTA as membrane permeabilizer. In the last section, we highlight the need to investigate the stability of multicolor assays to ensure correct results as multiwell autoloaders are now commonly used. PMID- 27687991 TI - Transfer and consumption of oxygen during the cultivation of the ectomycorrhizal fungus Rhizopogon nigrescens in an airlift bioreactor. AB - The study had the objective of examining the aspects involved in the cultivation of ectomycorrhizal fungi for the production of commercially sustainable inoculant to attend the demands of the seedling nursery industry. It focused on certain parameters, such as the oxygen consumption levels, during the cultivation of the ectomycorrhizal fungus Rhizopogon nigrescens CBMAI 1472, which was performed in a 5-L airlift bioreactor. The dynamic method was employed to determine the volumetric coefficient for the oxygen transfer (k L a) and the specific oxygen uptake rate (Q O2 ). The results indicate that specific growth rates (MU X ) and oxygen consumption decline rapidly with time, affected mainly by increases in biomass concentration (X). Increases in X are obtained primarily by increases in the size of pellets that are formed, altering, consequently, the cultivation dynamics. This is the result of natural increases in transferring resistance that are observed in these environments. Therefore, to avoid critical conditions that affect viability and the productivity of the process, particular settings are discussed. PMID- 27687993 TI - Effective production of fermentable sugars from brown macroalgae biomass. AB - Brown macroalgae are renewable and sustainable biomass resources for the production of biofuels and chemicals, owing to their high levels of carbohydrates and low levels of lignin. To increase the biological usage of brown macroalgae, it is necessary to depolymerize the polysaccharides that generate macroalgal monomeric sugars or sugar derivatives and to convert them into fermentable sugars for the production of biofuels and chemicals. In this review, we discuss the chemical and enzymatic saccharification of the major carbohydrates found in brown macroalgae and the use of the resulting constituents in the production of biofuels and chemicals, as well as high-value health-benefiting functional oligosaccharides and sugars. We also discuss recently reported experimental results, novel enzymes, and technological breakthroughs that are related to polysaccharide depolymerization, fermentable sugar production, and the biological conversion of non-favorable sugars for fermentation using industrial microorganisms. This review provides a comprehensive perspective of the efficient utilization of brown macroalgae as renewable resources for the production of biofuels and chemicals. PMID- 27687992 TI - Adhesion of the genome-sequenced Lactococcus lactis subsp. cremoris IBB477 strain is mediated by specific molecular determinants. AB - Understanding the nature of mucus-microbe interactions will provide important information that can help to elucidate the mechanisms underlying probiotic adhesion. This study focused on the adhesive properties of the Lactococcus lactis subsp. cremoris IBB477 strain, previously shown to persist in the gastrointestinal tract of germ-free rats. The shear flow-induced detachment of L. lactis cells was investigated under laminar flow conditions. Such a dynamic approach demonstrated increased adhesion to bare and mucin-coated polystyrene for IBB477, compared to that observed for the MG1820 control strain. To identify potential genetic determinants giving adhesive properties to IBB477, the improved high-quality draft genome sequence comprising chromosome and five plasmids was obtained and analysed. The number of putative adhesion proteins was determined on the basis of surface/extracellular localisation and/or the presence of adhesion domains. To identify proteins essential for the IBB477 specific adhesion property, nine deletion mutants in chromosomal genes have been constructed and analysed using adhesion tests on bare polystyrene as well as mucin-, fibronectin- or collagen IV-coated polystyrene plates in comparison to the wild-type strain. These experiments demonstrated that gene AJ89_07570 encoding a protein containing DUF285, MucBP and four Big_3 domains is involved in adhesion to bare and mucin coated polystyrene. To summarise, in the present work, we characterised the adhesion of IBB477 under laminar flow conditions; identified the putative adherence factors present in IBB477, which is the first L. lactis strain exhibiting adhesive and mucoadhesive properties to be sequenced and demonstrated that one of the proteins containing adhesion domains contributes to adhesion. PMID- 27687994 TI - Stereospecificity of Corynebacterium glutamicum 2,3-butanediol dehydrogenase and implications for the stereochemical purity of bioproduced 2,3-butanediol. AB - The stereochemistry of 2,3-butanediol (2,3-BD) synthesis in microbial fermentations is important for many applications. In this work, we showed that Corynebacterium glutamicum endowed with the Lactococcus lactis genes encoding alpha-acetolactate synthase and decarboxylase activities produced meso-2,3-BD as the major end product, meaning that (R)-acetoin is a substrate for endogenous 2,3 butanediol dehydrogenase (BDH) activity. This is curious in view of the reported absolute stereospecificity of C. glutamicum BDH for (S)-acetoin (Takusagawa et al. Biosc Biotechnol Biochem 65:1876-1878, 2001). To resolve this discrepancy, the enzyme encoded by butA Cg was produced in Escherichia coli and purified, and the stereospecific properties of the pure protein were examined. Activity assays monitored online by 1H-NMR using racemic acetoin and an excess of NADH showed an initial, fast production of (2S,3S)-2,3-BD, followed by a slow (~20-fold lower apparent rate) formation of meso-2,3-BD. Kinetic parameters for (S)-acetoin, (R) acetoin, meso-2,3-BD and (2S,3S)-BD were determined by spectrophotometric assays. V max values for (S)-acetoin and (R)-acetoin were 119 +/- 15 and 5.23 +/- 0.06 MUmol min-1 mg protein-1, and K m values were 0.23 +/- 0.02 and 1.49 +/- 0.07 mM, respectively. We conclude that C. glutamicum BDH is not absolutely specific for (S)-acetoin, though this is the preferred substrate. Importantly, the low activity of BDH with (R)-acetoin was sufficient to support high yields of meso 2,3-BD in the engineered strain C. glutamicum DeltaaceEDeltapqoDeltaldhA(pEKEx2 als,aldB,butA Cg ). Additionally, we found that the BDH activity was nearly abolished upon inactivation of butA Cg (from 0.30 +/- 0.03 to 0.004 +/- 0.001 MUmol min-1 mg protein-1), indicating that C. glutamicum expresses a single BDH under the experimental conditions examined. PMID- 27687995 TI - Screening of novel bacteria for the 2,3-butanediol production. AB - Biotechnologically produced 2,3-butanediol (2,3-BDO) is a potential starting material for industrial bulk chemicals such as butadiene or methyl ethyl ketone which are currently produced from fossil feedstocks. So far, the highest 2,3-BDO concentrations have been obtained with risk group 2 microorganisms. In this study, three risk group 1 microorganisms are presented that are so far unknown for an efficient production of 2,3-BDO. The strains Bacillus atrophaeus NRS-213, Bacillus mojavensis B-14698, and Bacillus vallismortis B-14891 were evaluated regarding their ability to produce high 2,3-BDO concentrations with a broad range of different carbon sources. A maximum 2,3-BDO concentration of 60.4 g/L was reached with the strain B. vallismortis B-14891 with an initial glucose concentration of 200 g/L within 55 h in a batch cultivation. Besides glucose, B. vallismortis B-14891 converts 14 different substrates that can be obtained from residual biomass sources to 2,3-BDO. Therefore B. vallismortis B-14891 is a promising candidate for the large-scale production of 2,3-BDO with low-cost substrates. PMID- 27687996 TI - Assessment of active methanogenic archaea in a methanol-fed upflow anaerobic sludge blanket reactor. AB - Methanogenic archaea enrichment of a granular sludge was undertaken in an upflow anaerobic sludge blanket (UASB) reactor fed with methanol in order to enrich methylotrophic and hydrogenotrophic methanogenic populations. A microbial community assessment, in terms of microbial composition and activity-throughout the different stages of the feeding process with methanol and acetate-was performed using specific methanogenic activity (SMA) assays, quantitative real time polymerase chain reaction (qPCR), and high-throughput sequencing of 16S ribosomal RNA (rRNA) genes from DNA and complementary DNA (cDNA). Distinct methanogenic enrichment was revealed by qPCR of mcrA gene in the methanol-fed community, being two orders of magnitude higher with respect to the initial inoculum, achieving a final mcrA/16S rRNA ratio of 0.25. High-throughput sequencing analysis revealed that the resulting methanogenic population was mainly composed by methylotrophic archaea (Methanomethylovorans and Methanolobus genus), being also highly active according to the RNA-based assessment. SMA confirmed that the methylotrophic pathway, with a direct conversion of methanol to CH4, was the main step of methanol degradation in the UASB. The biomass from the UASB, enriched in methanogenic archaea, may bear great potential as additional inoculum for bioreactors to carry out biogas production and other related processes. PMID- 27687997 TI - Organogenesis and foetal haemodynamics during the normal gestation of healthy black-rumped agoutis (Dasyprocta prymnolopha, Wagler, 1831) bred in captivity. AB - The objective of this study was to define the patterns of organogenesis and foetal haemodynamics during the normal gestation of healthy agoutis (Dasyprocta prymnolopha) kept in captivity. Thirty pregnant agoutis that ranged in size from small to medium and weighed between 2.5 and 3 kg underwent B-mode and Doppler ultrasonography for the biometric evaluation of the foetal organs. The foetal aortic blood flow proved to be predominantly systolic, and the measured flow velocity was 78.89 +/- 2.95 cm/s, with a maximum pressure gradient of 2.12 +/- 0.27 mmHg. The liver was characterized by its large volume, occupying the entire cranial aspect of the abdominal cavity, and it was associated cranially with the diaphragm and caudally with the stomach. The flow velocity in the portal vein was estimated to equal 12.17 +/- 2.37 cm/s, with a resistivity index of 0.82 +/- 0.05. The gallbladder was centrally located and protruded cranially towards the diaphragm. The spleen was visualized as an elongated structure with tapered cranial and caudal extremities, and the foetal kidneys were visualized bilaterally in the retroperitoneal region, with the right kidney positioned slightly more cranially than the left. The morphological characterization and hemodynamic analysis of the foetal organs of black-rumped agoutis via B-mode and Doppler ultrasonography allow determination of the vascular network and of reference values for the blood flow required for perfusing the anatomical elements essential for maintaining the viability of foetuses at different gestational ages. PMID- 27687999 TI - A proteomic approach for the identification of immunotoxic properties of Tulipalin A. AB - The immune system is permanently exposed to several environmental influences that can have adverse effects on immune cells or organs leading to immunosuppression or inappropriate immunostimulation, called direct immunotoxicity. The natural compound Tulipalin A (TUPA), a lactone with alpha-methylene-gamma-butyrolactone moiety, can influence the immune system and lead to allergic contact dermatitis. This in vitro study focused on effects of TUPA using two immune cell lines (Jurkat T cells and THP-1 monocytes). To evaluate the immunotoxic potential of the compound, a proteomic approach applying 2D gel electrophoresis and MALDI TOF/TOF-MS in combination with metabolomic analysis was used after exposure of the cells to IC10 of TUPA. THP-1 cells showed a strong robustness to TUPA treatment since only five proteins were altered. In contrast, in Jurkat T cells an increase in the abundance of 66 proteins and a decrease of six proteins was determined. These intracellular proteins were mapped to biological processes. Especially an accumulation of chaperones and an influence on the purine synthesis were observed. The changes in purine synthesis were confirmed by metabolomic analysis. In conclusion, the data indicate possible target processes of low doses of TUPA in Jurkat T cells and provides knowledge of how TUPA affects the functionality of immune cells.

A diagnosis of nonbacterial thrombotic embolism was made, and he was discharged on anticoagulation therapy with subcutaneous low molecular heparin. PMID- 27687998 TI - Volatile Organic Compounds Emitted by Fungal Associates of Conifer Bark Beetles and their Potential in Bark Beetle Control. AB - Conifer bark beetles attack and kill mature spruce and pine trees, especially during hot and dry conditions. These beetles are closely associated with ophiostomatoid fungi of the Ascomycetes, including the genera Ophiostoma, Grosmannia, and Endoconidiophora, which enhance beetle success by improving nutrition and modifying their substrate, but also have negative impacts on beetles by attracting predators and parasites. A survey of the literature and our own data revealed that ophiostomatoid fungi emit a variety of volatile organic compounds under laboratory conditions including fusel alcohols, terpenoids, aromatic compounds, and aliphatic alcohols. Many of these compounds already have been shown to elicit behavioral responses from bark beetles, functioning as attractants or repellents, often as synergists to compounds currently used in bark beetle control. Thus, these compounds could serve as valuable new agents for bark beetle management. However, bark beetle associations with fungi are very complex. Beetle behavior varies with the species of fungus, the stage of the beetle life cycle, the host tree quality, and probably with changes in the emission rate of fungal volatiles. Additional research on bark beetles and their symbiotic associates is necessary before the basic significance of ophiostomatoid fungal volatiles can be understood and their applied potential realized. PMID- 27688001 TI - Evaluation of bacteriocinogenic activity, safety traits and biotechnological potential of fecal lactic acid bacteria (LAB), isolated from Griffon Vultures (Gyps fulvus subsp. fulvus). AB - BACKGROUND: Lactic acid bacteria (LAB) are part of the gut microbiota and produce ribosomally synthesized antimicrobial peptides or bacteriocins with interest as natural food preservatives and therapeutic agents. Bacteriocin-producing LAB are also attractive as probiotics. Griffon vultures (Gyps fulvus subspecies fulvus) are scavenger birds that feed almost exclusively on carrion without suffering apparent ill effects. Therefore, griffon vultures might be considered a reservoir of bacteriocin-producing lactic acid bacteria (LAB) with potential biotechnological applications. RESULTS: Griffon vulture feces were screened for LAB with antimicrobial activity, genes encoding bacteriocins, potential virulence determinants, susceptibility to antibiotics, genotyping and characterization of bacteriocins. In this study, from 924 LAB evaluated 332 isolates (36 %) showed direct antimicrobial activity against Gram-positive bacteria only. The molecular identification of the most antagonistic 95 isolates showed that enterococci was the largest LAB group with antimicrobial activity (91 %) and E. faecium (40 %) the most identified antagonistic species. The evaluation of the presence of bacteriocin structural genes in 28 LAB isolates with the highest bacteriocinogenic activity in their supernatants determined that most enterococcal isolates (75 %) encoded multiple bacteriocins, being enterocin A (EntA) the largest identified (46 %) bacteriocin. Most enterococci (88 %) were resistant to multiple antibiotics. ERIC-PCR and MLST techniques permitted genotyping and recognition of the potential safety of the bacteriocinogenic enterococci. A multiple-step chromatographic procedure, determination of the N terminal amino acid sequence of purified bacteriocins by Edman degradation and a MALDI TOF/TOF tandem MS procedure permitted characterization of bacteriocins present in supernatants of producer cells. CONCLUSIONS: Enterococci was the largest LAB group with bacteriocinogenic activity isolated from griffon vulture feces. Among the isolates, E. faecium M3K31 has been identified as producer of enterocin HF (EntHF), a bacteriocin with remarkable antimicrobial activity against most evaluated Listeria spp. and of elevated interest as a natural food preservative. E. faecium M3K31 would be also considered a safe probiotic strain for use in animal nutrition. PMID- 27688002 TI - Physical activity and motivational predictors of changes in health behavior and health among DM2 and CAD patients. AB - This study tested a physical activity intervention and the self-determination theory (SDT) process model of health-behavior change and health among 108 adult patients with both diabetes mellitus type 2 (DM2) and coronary artery disease (CAD). Patients were randomly assigned to an organized physical activity intervention group (led by instructors) or a non-physical activity control group. At baseline and after 12 months, we measured the following: needs satisfaction, autonomous and controlled motivation for physical activity, perceived competence for physical activity and blood sugar testing, physical activity and blood sugar testing, body weight, glucose control (HbA1c), and self-perceptions of general health and vitality. The intervention produced, as hypothesized, significant changes in all study variables in favor of the experimental group (Cohen's d effect sizes: 0.23-0.72), except the non-significant result for controlled motivation and body weight. The data supported the SDT process model, in which the effect of the intervention significantly predicted indirect changes in behavior and health through motivation variables. Considering the moderate to large effects on increases in motivation, behavior, and health, promoting organized physical activity programs that are perceived as need-supportive may have important health implications for patients with DM2 and CAD. PMID- 27688003 TI - High Triterpenic Acids Production in Callus Cultures from Fruit Pulp of Two Apple Varieties. AB - INTRODUCTION: Very rarely fruit pulp has been used in in vitro culture to produce secondary metabolites useful in promoting health. OBJECTIVES: The aims of this work were the study of the best conditions to obtain the callus cultures from the pulp of two varieties of apples, Golden Delicious (GD) and "Mela Rosa Marchigiana" (MRM), and the quali-quantitative analysis of secondary metabolites produced by the two in vitro callus cultures. METHODOLOGY: Callus was induced on both Murashige and Skoog and Gamborg B5 media containing various combinations of supplements. To achieve the maximum recovery of secondary metabolites produced, preliminary extraction tests were carried out on GD apple culture using two different organic solvents (MeOH and EtOAc). The quali-quantitative analysis of the methanolic extract of both cultures was carried out by ESI-MSn and GC-MS techniques. RESULTS: The GC-MS analysis revealed the presence of triterpenic acids, in particular, oleanolic, ursolic, maslinic, pomolic, tormentic, corosolic and annurcoic acid along with a phytosterol, beta-sitosterol. In addition, GD callus culture produced phloridzin, absent in the MRM culture. In this last culture, however, the total amount of secondary metabolites was markedly higher. The in vivo production of these bioactive compounds were also quantified in the GD and MRM apple pulps. CONCLUSION: Apple pulps produced higher amounts of triterpenic acids in vitro than in vivo. The present work can be considered a method to amplify the production of important secondary metabolites which exert beneficial effects on human health. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - Yinao (healthcare disturbance) refers to violent incidents directed against healthcare staff and facilities for financial benefit. In China, incidences of Yinao are widespread and increasing, but little is known of this phenomenon in the wider global community. This commentary investigates the factors behind Yinao to achieve a deeper understanding. Causes include a lack of trust in medical staff, fueled by costly medical expenses; difficulties in accessing treatment; poor treatment outcomes; high patient expectations; a misunderstanding or rejection of medical ethics; misleading media reports; and a complex appeals process. Both doctors and nurses have been the targets of violent and distressing Yinao events, resulting in emotional pain, physical injury, and even death. In response, hospitals have established a series of preventative measures and and the government has increased the penalties for perpetrators of acts of Yinao. The situation is a salient reminder to policymakers worldwide of the importance of an accessible, affordable, and equitable health system. PMID- 27688005 TI - Magnitude-dependent and inversely-related osteogenic/chondrogenic differentiation of human mesenchymal stem cells under dynamic compressive strain. AB - Biomechanical forces have been shown to significantly affect tissue development, morphogenesis, pathogenesis and healing, especially in orthopaedic tissues. Such biological processes are critically related to the differentiation of human mesenchymal stem cells (hMSCs). However, the mechanistic details regarding how mechanical forces direct MSC differentiation and subsequent tissue formation are still elusive. Electrospun three-dimensional scaffolds were used to culture and subject hMSCs to various magnitudes of dynamic compressive strains at 5, 10, 15 or 20% (epsilon = 0.05, 0.10, 0.15, 0.20) at a frequency of 1 Hz for 2 h daily for up to 28 days in osteogenic media. Gene expression of chondrogenic markers (ACAN, COL2A1, SOX9) and glycosaminoglycan (GAG) synthesis were upregulated in response to the increased magnitudes of compressive strain, whereas osteogenic markers (COL1A1, SPARC, RUNX2) and calcium deposition had noticeable decreases by compressive loading in a magnitude-dependent manner. Dynamic mechanical analysis showed enhanced viscoelastic modulus with respect to the increased dynamic strain peaking at 15%, which coincides with the maximal GAG synthesis. Furthermore, polarization-sensitive optical coherence tomography revealed that mechanical loading enhanced the alignment of extracellular matrix to the greatest level by 15% strain as well. Overall, we show that the degree of differentiation of hMSCs towards osteogenic or chondrogenic lineage is inversely related, and it depends on the magnitude of dynamic compressive strain. These results demonstrate that multiphenotypic differentiation of hMSCs can be controlled by varying the strain regimens, providing a novel strategy to modulate differentiation specification and tissue morphogenesis.

AB - Emotional state may influence cognitive processes such as attention and decision making. A cognitive judgement bias is the propensity to anticipate either positive or negative consequences in response to ambiguous information. Recent work, mainly on vertebrates, showed that the response to ambiguous stimuli might change depending on an individual's affective state, which is influenced by e.g. the social and physical environment. However, the response to ambiguous stimuli could also be affected by the individual's behavioural type (personality), a question that has been under-investigated. We studied the link between individual differences in exploratory activity and the response to an ambiguous stimulus in the ant Camponotus aethiops. Exploratory behaviour, quantified with an open-field test, was variable among individuals but consistent over time within individuals. Individual ants learned to associate a spatial position to a reinforcement and another spatial position to a punishment. Once the ants had acquired this discrimination, cognitive judgement bias was tested with the stimulus in an intermediate position. Fast explorers in the open-field took significantly more time to approach the ambiguous stimulus compared to slow explorers, suggesting a negative judgement bias for fast explorers and a positive bias for slow explorers. This previously unknown link between individual difference in exploratory activity and cognitive bias in a social insect may help understanding the evolution and organization of social life. PMID- 27688006 TI - Moderate Alcohol Consumption and Chronic Disease: The Case for a Long-Term Trial. AB - Drinking within recommended limits is highly prevalent in much of the world, and strong epidemiological associations exist between moderate alcohol consumption and risk of several major chronic diseases, including coronary heart disease, diabetes, and breast cancer. In many cases, plausible biological mediators for these associations have been identified in randomized trials, but gold standard evidence that moderate drinking causes or prevents any chronic disease remains elusive and important concerns about available evidence have been raised. Although long-term randomized trials to test the observed associations have been termed impossible, clinical investigators have now successfully completed randomized trials of complex nutritional interventions in a variety of settings, along with trials of alcohol consumption itself of up to 2 years duration. The successful completion of these trials suggests that objections to the execution of a full-scale, long-term clinical trial of moderate drinking on chronic disease are increasingly untenable. We present potential lessons learned for such a trial and discuss key features to maximize its feasibility and value. PMID- 27688008 TI - Resection of tumors of the third ventricle involving the hypothalamus: effects on body mass index using a dedicated surgical approach. AB - Resection of large lesions growing into the third ventricle is considered nowadays still a demanding surgery, due to the high risk of severe endocrine and neurological complications. Some neurosurgical approaches were considered in the past the procedures of choice to access the third ventricle, however they were burden by endocrine and neurological consequences, like memory loss and epilepsy. We report here the endocrine and functional results in a series of patients operated with a recently developed approach specifically tailored for the resection of large lesions growing into the third ventricle. Authors conducted a retrospective analysis on 10 patients, operated between 2011 and 2012, for the resection of large tumors growing into the third ventricle. Total resection was achieved in all patients. No perioperative deaths were recorded and all patients were alive after the follow-up. One year after surgery 8/10 patients had an excellent outcome with a Karnofsky Performance Status of 100 and a Glasgow Outcome score of 5, with 8 patients experiencing an improvement of the Body Mass Index. Modern neurosurgery allows a safe and effective treatment of large lesions growing into the third ventricle with a postoperative good functional status. PMID- 27688009 TI - 10-year follow-up study comparing primary medical vs. surgical therapy in women with prolactinomas. AB - While dopamine-agonists are the first-line approach in treating prolactinomas, surgery can be considered in selected cases besides non-responders or patients with dopamine-agonist intolerance. The aim of the present study was to compare the long-term outcome in women with prolactinomas treated primarily either surgically or medically who had not had prior dopamine-agonist treatment. Retrospective case-note study of all consecutive women with prolactinomas primarily managed with medical therapy or surgery in a tertiary referral centre. The clinical, biochemical, and radiological responses to first-line treatment at early and long-term follow-up were analysed. The primary therapeutic strategy was dopamine-agonists for 36 (34 %) and surgery for 71 (66 %) of the women. Baseline clinical and biochemical characteristics were not significantly different between the primary surgical and medical cohort. Median follow-up time was 90 months (range 13-408). Following primary treatment, prolactin level significantly decreased in both cohorts, on average to 13.5 ug/L (IQR 7-21; p < 0.001), and was within the normal range in 82 % of all patients. No women in the surgical cohort demonstrated permanent sequelae and morbidity was low. At final follow-up, control of hyperprolactinaemia required dopamine-agonist therapy in 64 % of women who had undergone primary medical therapy vs. 32 % of those who had primary surgical therapy (p = 0.003). Logistic regression revealed that the primary therapeutic strategy, but not adenoma size, was an independent risk factor for long-term dependence on dopamine-agonists. The present data indicate that in a dedicated tertiary referral centre, long-term control of hyperprolactinaemia in women with prolactinomas is high. In selected cases, a primary neurosurgical approach might at least be interdisciplinarily discussed with the primary goal of minimizing long-term dependence on dopamine-agonists. PMID- 27688010 TI - Comparison of the therapeutic effects of prednisolone and nonsteroidal anti inflammatory drugs in patients with subacute thyroiditis. AB - Subacute thyroiditis is a transient inflammatory thyroid disease of unknown etiology. The primary goal for treatment is to mitigate inflammation. The aim of this retrospective study was to compare the therapeutic effects of prednisolone and nonsteroidal anti-inflammation drugs in patients with subacute thyroiditis. In this study, 53 consecutive Japanese patients who had been diagnosed with were referred to our hospital for further management. After excluding 11 patients (9 did not need treatment, 2 did not meet the criteria for diagnosis of subacute thyroiditis), the remaining 42 patients were treated either with prednisolone (n = 25) or loxoprofen (n = 17). We compared the time periods required for resolution of clinical symptoms and signs and normalization of thyroid function between the two groups. The mean dose of prednisolone was 15.0 (range, 14-16) mg/day and that of loxoprofen was 180 mg/day. The time period to normalization of thyroid function was comparable between the prednisolone and loxoprofen groups (25, 18-36, vs 32, 21-39 days, p = 0.388). However, the time period for resolution of symptoms was shorter under prednisolone than loxoprofen (7, 7-12 days, vs 21, 14-32 days, p < 0.001). Prednisolone treatment of patients with subacute thyroiditis was superior to nonsteroidal anti-inflammation drugs with regard to resolution of symptoms. PMID- 27688011 TI - Frequency, pattern, and outcome of recurrences after gamma knife radiosurgery for pituitary adenomas. AB - Gamma Knife radiosurgery is often used in pituitary adenomas. Aim of our study is to describe the characteristics and long-term outcome of patients with adenoma recurrence after Gamma Knife radiosurgery. We conducted a retrospective analysis of patients with pituitary adenoma treated by Gamma Knife radiosurgery between 1994 and 2014. Tumor recurrence was labeled as "in field" when the tumor growth occurred adjacent or within the prescribed isodose, whereas it was classified as "out of field" when the tumor growth occurred outside the prescribed isodose. Five hundred forty-three patients were included, 272 (50.1 %) had a nonfunctioning pituitary adenoma (NFPA) and 271 (49.9 %) patients had a hormone secreting-pituitary adenoma. The median follow-up after GKRS was 78 months (IQR, 36-125 months). Thirty-nine patients (7.2 %) had recurrence of disease and it was more frequent in patients with NFPA than in patients with hormone secreting adenomas (9.6 % vs. 4.8 %). The 10-yr progression-free survival in patients with NFPA was 78.7 % (95 % CI 69.5 - 87.9 %), as compared with 93.3 % (95 % CI 89.3 - 97.3 %; p < 0.01) in hormone secreting adenomas. Tumor recurrence was "in field" in 17 cases (43.6 %) and "out of field" in 22 cases (56.4 %). Seven of the 39 patients with recurrence died despite further treatments. Six of these patients had an "in field" recurrence. Recurrence of a pituitary adenoma after GKRS may occur several years after initial treatment. Distinction between "in field" and "out of field" tumor recurrence probably reflects two different pathophysiological mechanisms and may have prognostic importance.

AB - Two independent lines of inquiry suggest that growing up under conditions of contextual adversity (e.g., poverty and household chaos) accelerates aging and undermines long-term health. Whereas work addressing the developmental origins of health and disease highlights accelerated-aging effects of contextual adversity on telomere erosion, that informed by an evolutionary analysis of reproductive strategies highlights such effects with regard to pubertal development (in females). That both shorter telomeres early in life and earlier age of menarche are associated with poor health later in life raises the prospect, consistent with evolutionary life-history theory, that these two bodies of theory and research are tapping into the same evolutionary-developmental process whereby longer term health costs are traded off for increased probability of reproducing before dying via a process of accelerated aging. Here we make the case for such a claim, while highlighting biological processes responsible for these effects, as well as unknowns in the epigenetic equation that might instantiate these contextually regulated developmental processes. PMID- 27688013 TI - Effects of the single and combined treatment with dopamine agonist, somatostatin analog and mTOR inhibitors in a human lung carcinoid cell line: an in vitro study. AB - Somatostatin analogues and mTOR inhibitors have been used as medical therapy in lung carcinoids with variable results. No data are available on dopamine agonists as treatment for lung carcinoids. The main aim of the current study was to evaluate the effect of the combined treatment of somatostatin analogue octreotide and the dopamine agonist cabergoline with mTOR inhibitors in an in vitro model of typical lung carcinoids: the NCI-H727 cell line. In NCI-H727 cell line, reverse transcriptase-quantitative polymerase chain reaction and immunofluorescence were assessed to characterize the expression of the somatostatin receptor 2 and 5, dopamine receptor 2 and mTOR pathway components. Fifteen typical lung carcinoids tissue samples have been used for somatostatin receptor 2, dopamine receptor 2, and the main mTOR pathway component p70S6K expression and localization by immunohistochemistry. Cell viability, fluorescence-activated cell sorting analysis and western blot have been assessed to test the pharmacological effects of octreotide, cabergoline and mTOR inhibitors, and to evaluate the activation of specific cell signaling pathways in NCI-H727 cell line. NCI-H727 cell line expressed somatostatin receptor 2, somatostatin receptor 5 and dopamine receptor 2 and all mTOR pathway components at messenger and protein levels. Somatostatin receptor 2, dopamine receptor 2, and p70S6K (non phosphorylated and phosphorylated) proteins were expressed in most typical lung carcinoids tissue samples. Octreotide and cabergoline did not reduce cell viability as single agents but, when combined with mTOR inhibitors, they potentiate mTOR inhibitors effect after long-term exposure, reducing Akt and ERK phosphorylation, mTOR escape mechanisms, and increasing the expression DNA-damage-inducible transcript 4, an mTOR suppressor. In conclusion, the single use of octreotide and cabergoline is not sufficient to block cell viability but the combined approach of these agents with mTOR inhibitors might reduce the mTOR inhibitors-induced escape mechanisms and/or activate the endogenous mTOR suppressor, potentiating the effect of the mTOR inhibitors in an in vitro model of typical lung carcinoids. PMID- 27688016 TI - Probiotics for the Prevention of Pediatric Antibiotic-Associated Diarrhea. AB - : Goldenberg JZ, Lytvyn L, Steurich J, Parkin P, Mahant S, Johnston BC. Probiotics for the prevention of pediatric antibiotic-associated diarrhea.Cochrane Database Syst Rev2015, Issue 12. Art. No.: CD004827. http://dx.doi.org/10.1002/14651858.CD004827.pub4. BACKGROUND: Antibiotics are frequently prescribed in children. They alter the microbial balance within the gastrointestinal tract, commonly resulting in antibiotic-associated diarrhea (AAD). Probiotics may prevent AAD via restoration of the gut microflora. OBJECTIVES: The primary objectives were to assess the efficacy and safety of probiotics (any specified strain or dose) used for the prevention of AAD in children. SEARCH METHODS: MEDLINE, EMBASE, CENTRAL, CINAHL, AMED, and the Web of Science (inception to November 2014) were searched along with specialized registers including the Cochrane IBD/FBD review group, CISCOM (Centralized Information Service for Complementary Medicine), NHS Evidence, the International Bibliographic Information on Dietary Supplements, as well as trial registries. Letters were sent to authors of included trials, nutraceutical and pharmaceutical companies, and experts in the field requesting additional information on ongoing or unpublished trials. Conference proceedings, dissertation abstracts, and reference lists from included and relevant articles were also searched. SELECTION CRITERIA: Randomized, parallel, controlled trials in children (0-18 years) receiving antibiotics, that compare probiotics to placebo, active alternative prophylaxis, or no treatment and measure the incidence of diarrhea secondary to antibiotic use were considered for inclusion. DATA COLLECTION AND ANALYSIS: Study selection, data extraction, and methodological quality assessment using the risk of bias instrument were conducted independently and in duplicate by two authors. Dichotomous data (incidence of diarrhea and adverse events) were combined using a pooled risk ratio (RR) or risk difference (RD), and continuous data (mean duration of diarrhea and mean daily stool frequency) as mean difference (MD), along with their corresponding 95% confidence interval (95% CI). For overall pooled results on the incidence of diarrhea, sensitivity analyses included available case versus extreme-plausible analyses and random- versus fixed-effect models. To explore possible explanations for heterogeneity, a priori subgroup analysis was conducted on probiotic strain, dose, definition of antibiotic associated diarrhea, and risk of bias. We also conducted post hoc subgroup analyses by patient diagnosis, single versus multi-strain, industry sponsorship, and inpatient status. The overall quality of the evidence supporting the outcomes was evaluated using the GRADE criteria. MAIN RESULTS: Overall, 23 studies (3938 participants) met the inclusion criteria. Trials included treatment with either Bacillus spp., Bifidobacterium spp., Clostridium butyricum, Lactobacilli spp., Lactococcus spp., Leuconostoc cremoris, Saccharomyces spp., or Streptococcus spp., alone or in combination. Eleven studies used a single-strain probiotic, four combined two probiotic strains, three combined three probiotic strains, one combined four probiotic strains, two combined seven probiotic strains, one included ten probiotic strains, and one study included two probiotic arms that used three and two strains, respectively. The risk of bias was determined to be high or unclear in 13 studies and low in 10 studies. Available case (patients who did not complete the studies were not included in the analysis) results from 22/23 trials reporting on the incidence of diarrhea show a precise benefit from probiotics compared to active, placebo, or no treatment control. The incidence of AAD in the probiotic group was 8% (163/1992) compared to 19% (364/1906) in the control group (RR = 0.46; 95% CI: 0.35-0.61; I2 = 55%, 3898 participants). A GRADE analysis indicated that the overall quality of the evidence for this outcome was moderate. This benefit remained statistically significant in an extreme-plausible (60% of children lost to follow-up in probiotic group and 20% lost to follow-up in the control group had diarrhea) sensitivity analysis, where the incidence of AAD in the probiotic group was 14% (330/2294) compared to 19% (426/2235) in the control group (RR = 0.69; 95% CI: 0.54-0.89; I2 = 63%, 4529 participants). None of the 16 trials (n = 2455) that reported on adverse events documented any serious adverse events attributable to probiotics. Meta-analysis excluded all but an extremely small non-significant difference in adverse events between treatment and control (RD = 0.00, 95% CI: -0.01 to 0.01). The majority of adverse events were in placebo, standard care, or no treatment group. Adverse events reported in the studies include rash, nausea, gas, flatulence, abdominal bloating, abdominal pain, vomiting, increased phlegm, chest pain, constipation, taste disturbance, and low appetite. AUTHORS' CONCLUSIONS: Moderate quality evidence suggests a protective effect of probiotics in preventing AAD. Our pooled estimate suggests a precise (RR 0.46; 95% CI: 0.35-0.61) probiotic effect with an NNT of 10. Among the various probiotics evaluated, Lactobacillus rhamnosus or Saccharomyces boulardii at 5-40 billion colony-forming units/day may be appropriate given the modest NNT and the likelihood that adverse events are very rare. It is premature to draw conclusions about the efficacy and safety of other probiotic agents for pediatric AAD. Although no serious adverse events were observed among otherwise healthy children, serious adverse events have been observed in severely debilitated or immunocompromised children with underlying risk factors including central venous catheter use and disorders associated with bacterial/fungal translocation. Until further research has been conducted, probiotic use should be avoided in pediatric populations at risk for adverse events. Future trials would benefit from a standard and valid outcomes to measure AAD.

AB - CONTEXT: School-based mindfulness and yoga studies generally measure stress related outcomes using quantitative measures. OBJECTIVE: This study answers the following research questions: How do youth define stress and in what ways, if any, was a mindful yoga intervention helpful to youth during stress experiences? DESIGN AND SUBJECTS: To explore youths' own perspectives on stress, stressors in youths' lives, and perceived changes in responses to stress post-intervention, we conducted focus group discussions with 22 middle school students from low-income urban communities following a 16-week mindful yoga intervention. RESULTS: Using thematic analysis, the following three themes emerged: (1) youth conflated stress with negative emotions; (2) peer and family conflicts were common stressors; and (3) youth reported improved impulse control and emotional regulation following the intervention. Study findings have implications for refining intervention content (e.g., discussions of stress), as well as informing the selection and development of quantitative measures for future research on stress and stress responses in urban youth. PMID- 27688018 TI - Improved detection of soma location and morphology in fluorescence microscopy images of neurons. AB - BACKGROUND: Automated detection and segmentation of somas in fluorescent images of neurons is a major goal in quantitative studies of neuronal networks, including applications of high-content-screenings where it is required to quantify multiple morphological properties of neurons. Despite recent advances in image processing targeted to neurobiological applications, existing algorithms of soma detection are often unreliable, especially when processing fluorescence image stacks of neuronal cultures. NEW METHOD: In this paper, we introduce an innovative algorithm for the detection and extraction of somas in fluorescent images of networks of cultured neurons where somas and other structures exist in the same fluorescent channel. Our method relies on a new geometrical descriptor called Directional Ratio and a collection of multiscale orientable filters to quantify the level of local isotropy in an image. To optimize the application of this approach, we introduce a new construction of multiscale anisotropic filters that is implemented by separable convolution. RESULTS: Extensive numerical experiments using 2D and 3D confocal images show that our automated algorithm reliably detects somas, accurately segments them, and separates contiguous ones. COMPARISON WITH EXISTING METHODS: We include a detailed comparison with state-of the-art existing methods to demonstrate that our algorithm is extremely competitive in terms of accuracy, reliability and computational efficiency. CONCLUSIONS: Our algorithm will facilitate the development of automated platforms for high content neuron image processing. A Matlab code is released open-source and freely available to the scientific community. PMID- 27688019 TI - Self-immolation: A cultural view.

AB - Granulocytic-macrophage colony-stimulating factor (GM-CSF) is used as an adjuvant in cancer vaccine trials and has the potential to enhance antitumor efficacy with immunotherapy; however, its immunologic effects are not fully understood. Here, we report results from a phase I study of neoadjuvant GM-CSF in patients with localized prostate cancer undergoing radical prostatectomy. Patients received subcutaneous injections of GM-CSF (250 MUg/m2/day) daily for 2 weeks (cohort 1; n = 6), 3 weeks (cohort 2; n = 6), or 4 weeks (cohort 3; n = 6). Treatment was well tolerated with all grade 1 or 2 adverse events. Two patients had a decline in prostate-specific antigen (PSA) of more than 50%. GM-CSF treatment increased the numbers of circulating mature myeloid dendritic cells, proliferating conventional CD4 T cells, proliferating CD8 T cells, and to a lesser magnitude FoxP3+ regulatory CD4 T cells. Although GM-CSF treatment did not augment antigen presenting cell localization to the prostate, treatment was associated with recruitment of CD8+ T cells to the tumor. These results suggest that systemic GM CSF can modulate T-cell infiltration in the tumor microenvironment. Cancer Immunol Res; 4(11); 948-58. (c)2016 AACR. PMID- 27688022 TI - Early group psychoeducation for bipolar disorder. PMID- 27688021 TI - Clinical effectiveness and acceptability of structured group psychoeducation versus optimised unstructured peer support for patients with remitted bipolar disorder (PARADES): a pragmatic, multicentre, observer-blind, randomised controlled superiority trial. AB - BACKGROUND: Group psychoeducation is a low-cost National Institute for Health and Care Excellence-recommended treatment for bipolar disorder. However, the clinical effectiveness and acceptability of this intervention are unclear compared with unstructured peer support matched for delivery and aim of treatment, and for previous bipolar history. We aimed to assess the clinical effectiveness and acceptability of structured group psychoeducation versus optimised unstructured peer support for patients with remitted bipolar disorder. METHODS: We did this pragmatic, multicentre, parallel-group, observer-blind, randomised controlled superiority trial at eight community sites in two regions in England. Participants aged 18 years or older with bipolar disorder and no episode in the preceding 4 weeks were recruited via self-referral or secondary care referral. Participants were individually randomly assigned (1:1), via a computer-generated stochastic allocation sequence, to attend 21 2-h weekly sessions of either structured group psychoeducation or optimised unstructured peer support. Randomisation was minimised by number of previous episodes (one to seven, eight to 19, or >=20) and stratified by clinical site. Outcome assessors were masked to group allocation. The primary outcome was time from randomisation to next bipolar episode, with planned moderator analysis of number of previous bipolar episodes and qualitative interview of participant experience. We did analysis by intention to treat. This trial is registered with the International Standard Randomised Controlled Trial registry, number ISRCTN62761948. FINDINGS: Between Sept 28, 2009, and Jan 9, 2012, we randomly assigned 304 participants to receive psychoeducation (n=153) or peer support (n=151); all (100%) participants had complete primary outcome data. Attendance at psychoeducation groups was higher than at peer-support groups (median 14 sessions [IQR three to 18] vs nine sessions [two to 17]; p=0.026). At 96 weeks, 89 (58%) participants in the psychoeducation group had experienced a next bipolar episode compared with 98 (65%) participants in the peer-support group; time to next bipolar episode did not differ between groups (hazard ratio [HR] 0.83, 95% CI 0.62-1.11; p=0.217). Planned moderator analysis showed that psychoeducation was most beneficial in participants with few (one to seven) previous bipolar episodes (chi2; HR 0.28, 95% CI 0.12-0.68; p=0.034). Four (1%) participants (one in the psychoeducation group and three in the peer-support group) died during follow-up; these deaths were deemed unrelated to the study interventions or procedures. INTERPRETATION: Structured group psychoeducation was no more clinically effective than similarly intensive unstructured peer support, but was more acceptable and improved outcome in participants with fewer previous bipolar episodes. Optimum provision of structured psychological interventions, such as group psychoeducation, early in the course of bipolar disorder might have important benefits on the course of illness, and merits further research.

AB - Glycoside hydrolases are divided into two groups, known as inverting and retaining enzymes, based on their hydrolytic mechanisms. Glycoside hydrolase family 63 (GH63) is composed of inverting alpha-glycosidases, which act mainly on alpha-glucosides. We previously found that Escherichia coli GH63 enzyme, YgjK, can hydrolyze 2-O-alpha-d-glucosyl-d-galactose. Two constructed glycosynthase mutants, D324N and E727A, which catalyze the transfer of a beta-glucosyl fluoride donor to galactose, lactose, and melibiose. Here, we determined the crystal structures of D324N and E727A soaked with a mixture of glucose and lactose at 1.8 and 2.1-A resolutions, respectively. Because glucose and lactose molecules are found at the active sites in both structures, it is possible that these structures mimic the enzyme-product complex of YgjK. A glucose molecule found at subsite -1 in both structures adopts an unusual 1S3 skew-boat conformation. Comparison between these structures and the previously determined enzyme substrate complex structure reveals that the glucose pyranose ring might be distorted immediately after nucleophilic attack by a water molecule. These structures represent the first enzyme-product complex for the GH63 family, as well as the structurally-related glycosidases, and it may provide insight into the catalytic mechanism of these enzymes.

A structured communication approach, placing patients' perspectives at the heart of discussions about their care, was used to improve patients' quality of life in secure settings. The objectives were to: * Establish the feasibility of the trial design * Determine the variability of the outcomes of interest * Estimate the costs of the intervention * If necessary, refine the intervention METHODS: A pilot cluster randomised controlled trial was conducted. Data was collected from July 2012 to January 2015 from participants in 6 medium secure in-patient services in London and Southern England. 55 patients and 47 nurses were in the intervention group with 57 patients and 45 nurses in the control group. The intervention comprised 6 nurse-patient meetings over a 6 month period. Patients rated their satisfaction with a range of domains followed by discussions on improving patient identified problems. Assessments took place at baseline, 6 months, and 12 months. Participants were not blind to their allocated group. The primary outcome was self-reported quality of life collected by a researcher blind to participants' allocation status. RESULTS: The randomisation procedures and intervention approach functioned well. The measures used were understood by the participants and gave relevant outcome information. The response rates were good with low patient withdrawal rates. The quality of life estimated treatment effect was 0.2 (95 % CI: -0.4 to 0.8) at 6 months and 0.4 (95 % CI: -0.3 to 1.1) indicating the likely extreme boundaries of effect in the main trial. The estimated treatment effect of the primary outcome is clinically important, and a positive effect of the intervention is not ruled out. The estimate of the ICC for the primary outcome at 6 and 12 months was 0.04 (0.00 to 0.17) and 0.05 (0.00 to 0.18). The cost of the intervention was L529 per patient. CONCLUSIONS: The trial design was viable as the basis for a full-scale trial. A full trial is justified to estimate the effect of the intervention with greater certainty. The variability of the outcomes could be used to calculate numbers needed for a full-scale trial. Ratings of need for therapeutic security may be useful in any future study.

PMID- 27688025 TI - Completeness of Spontaneous Adverse Drug Reaction Reports Sent by General Practitioners to a Regional Pharmacovigilance Centre: A Descriptive Study. AB - INTRODUCTION: Spontaneous reporting of adverse drug reactions (ADRs) remains the cornerstone of postmarketing drug safety surveillance (pharmacovigilance); however, one of its main limitations is incomplete data, thus limiting conclusions about causality assessment. OBJECTIVE: The primary aim of this study was to assess the completeness of ADR reports sent by general practitioners (GPs) to regional pharmacovigilance centres and the secondary objective was to identify factors associated with complete ADR reports. METHODS: All ADR reports sent by GPs to the Midi-Pyrenees Regional Pharmacovigilance Center (Toulouse, France) from 1 January 2010 to 31 December 2013 were reviewed. Healthcare professionals and patients can forward an ADR using either an online form through the Pharmacology Information Bulletin website ( http://www.bip31.fr ) or 'traditional' ADR reports (i.e. email, letter or fax). According to information provided in ADR reports (i.e. patient identification, ADR, date of occurrence, clinical description, drugs, etc.), reports were classified into three groups: 'well-documented', 'slightly documented' or 'poorly documented'. A multivariate logistic regression was performed to investigate potential factors associated with a 'well-documented' ADR report. RESULTS: During the study period, 613 ADR reports were analysed. Among these reports, only 12.7 % were classified as 'well documented', 68.5 % as 'slightly documented' and 18.8 % as 'poorly documented'. An association between a 'well-documented' ADR report and its 'seriousness' was found (odds ratio = 1.70 [95 % CI 1.04-2.76], p = 0.01). No association between report completeness ('well-documented' report) and GP practice location or mode of ADR reporting was found. CONCLUSIONS: The study shows that only one out of eight ADR reports from GPs was 'well-documented'. Therefore, it appears to be important to promote further information being available regarding the data required in ADR reports to optimise the evaluation of drug causality. PMID- 27688026 TI - Estimating Herbal Product Authentication and Adulteration in India Using a Vouchered, DNA-Based Biological Reference Material Library. AB - INTRODUCTION: India is considered the 'medicinal garden' of the world, with 8000 medicinal plants of which 960 are commercial species that are traded nationally and globally. Although scientific studies estimate herbal product adulteration as 42-66 % in North America, India does not have any published marketplace studies and subsequent estimates of adulteration in an industry facing considerable supply demands. OBJECTIVES: The goal of this project is to provide an initial assessment of herbal product authentication and adulteration in the marketplace in India by (1) developing a biological reference material (BRM) herbal DNA library for Indian herbal species using DNA barcode regions (ITS2 and rbcL) in order to facilitate accurate species resolution when testing the herbal products; and (2) assessing herbal product identification using our BRM library; and (3) comparing the use of our BRM library to identify herbal products with that of GenBank. METHODS: A BRM herbal DNA library consisting of 187 herbal species was prepared to authenticate the herbal products within India. Ninty-three herbal products representing ten different companies were procured from local stores located at Coimbatore, India. These samples were subjected to blind testing for authenticity using the DNA barcode regions rbcL and ITS2. RESULTS: The results indicate that 40 % of the products tested are authentic, and 60 % of the products may be adulterated (i.e. contained species of plants not listed on the product labels). The adulterated samples included contamination (50 %), substitution (10 %) and fillers (6 %). Our BRM library provided a 100 % Basic Local Alignment Search Tool (BLAST) match for all species, whereas the GenBank match was 64 %. CONCLUSIONS: Our findings suggest that most Indian herbal medicinal products are essentially mixed with one or a few other herbs that could lessen the therapeutic activity of the main ingredients. We do not recommend the use of GenBank to identify herbal products because the use of this non-curated and/or vouchered database will result in inaccurate species identification. These DNA-based tools provide a scientific foundation for herbal pharmacovigilance to ensure the safety and efficacy of natural drugs. This study provides curated BRMs that will underpin innovations in molecular diagnostic biotechnology, which will soon provide more robust estimates of adulteration and commercial tools that will strengthen due diligence in quality assurance within the herbal industry. PMID- 27688027 TI - Role of glypican-1 in endothelial NOS activation under various steady shear stress magnitudes. AB - Blood flow patterns in proatherogenic and antiatherogenic regions are rather different. We hypothesize that the laminar flow with steady shear stress increased nitric oxide (NO) bioavailability while disturbed flow with low shear stress reduced it, which is mediating by glypican-1. Thus, we detected the expression of glypican-1 under different shear stress magnitudes, and tested whether the magnitude of shear stress determines the level of endothelial NO synthase (eNOS) via glypican-1 by using phosphatidylinositol phospholipase C (PI PLC). Results revealed that the expression of glypican-1 depends on the magnitude and duration of shear stress loading. Activation of eNOS in HUVECs is downregulated by 4dyn/cm2 of shear stress, but is upregulated by 15dyn/cm2. Removal of glypican-1 significantly suppressed the 15dyn/cm2 shear stress-induced eNOS activity, and further reduced the 4dyn/cm2-inhibited eNOS activity. Therefore, eNOS activation depends on shear stress magnitudes and is mediated by glypican-1. The role of glypican-1 in mediating the eNOS activation under shear stress might involve in protecting the endothelial function against disturbed flow and enhancing the sensitive of the endothelial cell to laminar flow, supporting a potential role of glypican-1 against atherosclerosis. PMID- 27688029 TI - Evaluation of the necessity for chest drain placement following thoracoscopic wedge resection. AB - PURPOSE: To evaluate the outcomes of patients who underwent thoracoscopic wedge resection without chest drain placement. METHODS: The subjects of this retrospective study were 89 patients, who underwent thoracoscopic wedge resection at our hospital between January, 2013 and July, 2015. A total of 45 patients whose underlying condition did not meet the following criteria were assigned to the "chest drain placement group" (group A): peripheral lesions, healthy lung parenchyma, no intraoperative air leaks, hemorrhage or effusion accumulation, and no pleural adhesion. The other 44 patients whose underlying condition met the criteria were assigned to the "no chest drain placement group" (group B). Patient characteristics, specimen data, and postoperative conditions were analyzed and compared between the groups. RESULTS: Group A patients had poorer forced expiratory volume in one second (FEV1) values, less normal spirometric results, significantly higher resected lung volume, a greater maximum tumor-pleura distance, and a larger maximum tumor size. They also had a longer postoperative hospital stay. There was no difference between the two groups in postoperative complications. CONCLUSIONS: Avoiding chest drain placement after a thoracoscopic wedge resection appears to be safe and beneficial for patients who have small peripheral lesions and healthy lung parenchyma. PMID- 27688028 TI - Early-stage heart failure with preserved ejection fraction in the pig: a cardiovascular magnetic resonance study. AB - BACKGROUND: The hypertensive deoxy-corticosterone acetate (DOCA)-salt-treated pig (hereafter, DOCA pig) was recently introduced as large animal model for early stage heart failure with preserved ejection fraction (HFpEF). The aim of the present study was to evaluate cardiovascular magnetic resonance (CMR) of DOCA pigs and weight-matched control pigs to characterize ventricular, atrial and myocardial structure and function of this phenotype model. METHODS: Five anesthetized DOCA and seven control pigs underwent 3 T CMR at rest and during dobutamine stress. Left ventricular/atrial (LV/LA) function and myocardial mass (LVMM), strains and torsion were evaluated from (tagged) cine imaging. 4D phase contrast measurements were used to assess blood flow and peak velocities, including transmitral early-diastolic (E) and myocardial tissue (E') velocities and coronary sinus blood flow. Myocardial perfusion reserve was estimated from stress-to-rest time-averaged coronary sinus flow. Global native myocardial T1 times were derived from prototype modified Look-Locker inversion-recovery (MOLLI) short-axis T1 maps. After in-vivo measurements, transmural biopsies were collected for stereological evaluation including the volume fractions of interstitium (VV(int/LV)) and collagen (VV(coll/LV)). Rest, stress, and stress-to rest differences of cardiac and myocardial parameters in DOCA and control animals were compared by t-test. RESULTS: In DOCA pigs LVMM (p < 0.001) and LV wall thickness (end-systole/end-diastole, p = 0.003/p = 0.007) were elevated. During stress, increase of LV ejection-fraction and decrease of end-systolic volume accounted for normal contractility reserves in DOCA and control pigs. Rest-to stress differences of cardiac index (p = 0.040) and end-diastolic volume (p = 0.042) were documented. Maximal (p = 0.042) and minimal (p = 0.012) LA volumes in DOCA pigs were elevated at rest; total LA ejection-fraction decreased during stress (p = 0.006). E' was lower in DOCA pigs, corresponding to higher E/E' at rest (p = 0.013) and stress (p = 0.026). Myocardial perfusion reserve was reduced in DOCA pigs (p = 0.031). T1-times and VV(int/LV) did not differ between groups, whereas VV(coll/LV) levels were higher in DOCA pigs (p = 0.044). CONCLUSIONS: LA enlargement, E' and E/E' were the markers that showed the most pronounced differences between DOCA and control pigs at rest. Inadequate increase of myocardial perfusion reserve during stress might represent a metrics for early stage HFpEF. Myocardial T1 mapping could not detect elevated levels of myocardial collagen in this model. TRIAL REGISTRATION: The study was approved by the local Bioethics Committee of Vienna, Austria (BMWF-66.010/0091-II/3b/2013). PMID- 27688030 TI - Association between the participation of board-certified surgeons in gastroenterological surgery and operative mortality after eight gastroenterological procedures. AB - PURPOSE: The aim of this study is to evaluate the association between the participation of board-certified surgeons in gastroenterological surgery (BCS-Gs) and the surgical outcomes of gastroenterological surgery. METHODS: Data from the National Clinical Database on patients who underwent eight major gastroenterological procedures were analyzed retrospectively. First, the ratio of cases in which BCS-G were involved to the total cases was calculated for each procedure, and the impact of BCS-G involvement on surgical outcome was assessed by comparing mortality rates in the group with BCS-G involvement vs. the group without BCS-G involvement. Second, the differences in the observed/expected ratio were assessed among four hospital categories according to the available BCS-G number. Finally, the impact of the hospital BCS-G number on mortality was evaluated. RESULTS: The ratio of BCS-G involvement ranged from 59.0 % for acute diffuse peritonitis to 89.1 % for hepatectomy, and the mortality rate was significantly lower for three procedures when BCS-Gs participated as the operator or assistant. The observed/expected ratio of hospitals with four or more BCS-Gs was less than 1.0 for all the procedures assessed. A multivariable logistic regression model showed that the hospital BCS-G number was a predictor of operative mortality. CONCLUSIONS: BCS-Gs contribute to favorable outcomes of gastroenterological surgery in Japan. The hospital BCS-G number is a surrogate marker of operative mortality. PMID- 27688031 TI - Safety and efficacy of an "enhanced recovery after surgery" protocol for patients undergoing colon cancer surgery: a multi-institutional controlled study. AB - PURPOSE: The aim of this multi-institutional study was to prospectively evaluate the safety and efficacy of an enhanced recovery after surgery (ERAS) protocol for colonic surgery. METHODS: The subjects of this study were 320 patients with an American Society of Anesthesiologists (ASA) grade I or II physical status. Patients underwent elective open or laparoscopic colonic resection or high anterior resection between April 2011 and January 2014 at one of six institutions. Three hospitals implemented an ERAS protocol (n = 159), and three administered conventional care (n = 161). The primary outcome measure was the surgical complication rate. RESULTS: Most operations, irrespective of group, were performed laparoscopically. The incidence of a surgical complication was 17.0 % in the ERAS group vs. 16.1 % in the conventional group (P = 0.842), in which several non-surgical complications also arose. Oral food intake was implemented earlier for the ERAS group vs. the conventional group, after a median (range) of 1 (1-31) vs. 3 (1-9) days for the ERAS vs. conventional care groups, respectively (P < 0.001). The median length of postoperative hospital stay was reduced by 5.5 days for the ERAS group, being 8.5 (5-41) vs. 14 (7-56) days for the ERAS vs. conventional care groups, respectively (P < 0.001). CONCLUSION: This multi institutional controlled study clearly demonstrated that an ERAS protocol was efficient, without increasing the complication risk. PMID- 27688032 TI - Treatment of simultaneously discovered lung cancer and cardiovascular disease: a 20-year single-institution experience. AB - PURPOSE: To propose a treatment strategy for simultaneously discovered non-small cell lung cancer (NSCLC) and cardiovascular disease (CVD). METHODS: Of 1302 patients who underwent surgery for NSCLC, CVD requiring invasive treatment was simultaneously discovered in 33 (3 %). The details of the treatments as well as the short- and long-term outcomes of pulmonary resection were analyzed. RESULTS: CVD included coronary artery disease in 20 patients, valvular disease in 6, abdominal aortic aneurysm in 5, and congenital heart disease in 2. Twenty-six patients underwent two-stage treatment, while seven received simultaneous surgery. In 23 patients whose treatment for CVD preceded that for lung cancer, the median interval between those treatments was 78 days (range 18-197 days). Postoperative complications occurred in 8 (31 %) of 26 patients who underwent 2 stage treatment and in 3 (43 %) of 7 who underwent simultaneous surgery. Notably, of 3 patients who underwent lobectomy or bilobectomy, 2 (67 %) experienced respiratory dysfunction that required intubation. The 5-year overall survival rate of all 33 patients was 84.5 %. CONCLUSION: The outcomes of two-stage treatment in the present cohort were favorable. Given our experience, simultaneous surgery for lung cancer and CVD should, therefore, be selected only for patients who may benefit from that strategy. PMID- 27688033 TI - Cloning, expression, molecular characterization and preliminary studies on immunomodulating properties of recombinant Trypanosoma congolense calreticulin. AB - Trypanosomes are bloodstream protozoan parasites, which are pathogens of veterinary and medical importance. Several mammalian species, including humans, can be infected by different species of the genus Trypanosoma (T. congolense, T. evansi, T. brucei, T. vivax) exhibiting more or less virulent and pathogenic phenotypes. A previous screening of the excreted-secreted proteins of T. congolense demonstrated an overexpression of several proteins correlated with the virulence and pathogenicity of the strain. Of these proteins, calreticulin (CRT) has shown differential expression between two T. congolense strains with opposite infectious behavior and has been selected as a target molecule based on its immune potential functions in parasitic diseases. In this study, we set out to determine the role of T. congolense calreticulin as an immune target. Immunization of mice with recombinant T. congolense calreticulin induced antibody production, which was associated with delayed parasitemia and increased survival of the challenged animal. These results strongly suggest that some excreted secreted proteins of T. congolense are a worthwhile target candidate to interfere with the infectious process. PMID- 27688034 TI - Baseline Motivation Type as a Predictor of Dropout in a Healthy Eating Text Messaging Program. AB - BACKGROUND: Growing evidence suggests that text messaging programs are effective in facilitating health behavior change. However, high dropout rates limit the potential effectiveness of these programs. OBJECTIVE: This paper describes patterns of early dropout in the HealthyYou text (HYTxt) program, with a focus on the impact of baseline motivation quality on dropout, as characterized by Self Determination Theory (SDT). METHODS: This analysis included 193 users of HYTxt, a diet and physical activity text messaging intervention developed by the US National Cancer Institute. Descriptive statistics were computed, and logistic regression models were run to examine the association between baseline motivation type and early program dropout. RESULTS: Overall, 43.0% (83/193) of users dropped out of the program; of these, 65.1% (54/83; 28.0% of all users) did so within the first 2 weeks. Users with higher autonomous motivation had significantly lower odds of dropping out within the first 2 weeks. A one unit increase in autonomous motivation was associated with lower odds (odds ratio 0.44, 95% CI 0.24-0.81) of early dropout, which persisted after adjusting for level of controlled motivation. CONCLUSIONS: Applying SDT-based strategies to enhance autonomous motivation might reduce early dropout rates, which can improve program exposure and effectiveness. PMID- 27688035 TI - Current status of laparoscopic pancreaticoduodenectomy and pancreatectomy. AB - This review describes the recent advances in, and current status of, minimally invasive pancreatic surgery (MIPS). Typical MIPS procedures are laparoscopic pancreaticoduodenectomy (LPD), laparoscopic distal pancreatectomy (LDP), laparoscopic central pancreatectomy (LCP), and laparoscopic total pancreatectomy (LTP). Some retrospective studies comparing LPD or LDP and open procedures have demonstrated the safety and feasibility as well as the intraoperative outcomes and postoperative recovery of these procedures. In contrast, LCP and LTP have not been widely accepted as common laparoscopic procedures owing to their complicated reconstruction and limited indications. Nevertheless, our concise review reveals that LCP and LTP performed by expert laparoscopic surgeons can result in good short-term and long-term outcomes. Moreover, as surgeons' experience with laparoscopic techniques continues to grow around the world, new innovations and breakthroughs in MIPS will evolve. Well-designed and suitably powered randomized controlled trials of LPD, LDP, LCP, and LTP are now warranted to demonstrate the superiority of these procedures. PMID- 27688037 TI - Hydrodisplacement of sural nerve for safety and efficacy of endovenous thermal ablation for small saphenous vein incompetence. AB - Background Endovenous radio frequency ablation for small saphenous vein incompetence by and large appears to be superior and safer than conventional open surgery. Small saphenous vein ablation from approximately mid-calf to the point proximally where the small saphenous vein dives into the popliteal fossa is considered to be safe, as the sural nerve is in most cases separated from this segment of the small saphenous vein by the deep fascia. The outcome of the distal incompetent small saphenous vein remains unclear. Efficacy of the endovenous radio frequency ablation can be enhanced by increasing the length of the ablatable small saphenous vein segment. Methodology To optimise endovenous radio frequency ablation outcome, the distal small saphenous vein may be made amenable to ablation if safety of the sural nerve can be assured. The sural nerve was successfully located using duplex ultrasound in 100% of our cohort in this study. The standard entry point for venous access was just above the lateral malleolus. After introduction of the introducer sheath, the radio frequency catheter was advanced proximally; the sural nerve was displaced from the small saphenous vein by approximately 1 cm with the administration of tumescent anaesthesia ( hydrodisplacement). A total of 118 patients underwent extended endovenous radio frequency ablation of 124 incompetent small saphenous vein trunks using the method described. Results Successful extended ablation of the small saphenous vein was achieved in 100% of cases and it was confirmed by duplex scanning at one and six weeks. Two neurological events were recorded during the study: 1. One patient with temporary foot drop lasting for less than 6 h with complete recovery. 2. A second patient with a sural nerve sensory deficit reported by the patient at day 2-3, which remains current at six weeks. Conclusions Extended endovenous radio frequency ablation of the small saphenous vein to optimise length of the ablatable vein segment is feasible with careful identification and hydrodisplacement of the sural nerve. This method is shown to be associated with fewer neurological complications than other methods reported in the literature. PMID- 27688036 TI - Effects of an endothelin receptor antagonist, Macitentan, on right ventricular substrate utilization and function in a Sugen 5416/hypoxia rat model of severe pulmonary arterial hypertension. AB - BACKGROUND: Altered myocardial energy metabolism has been linked to worsening of RV function in pulmonary arterial hypertension (PAH). The aim of this study was to evaluate RV glucose and fatty acid metabolism in vivo in a rat model of PAH using positron emission tomography (PET) and investigate the effects of Macitentan on RV substrate utilization. METHODS: PAH was induced in male Sprague Dawley rats by a single subcutaneous injection of Sugen 5416 (20 mg/kg) followed by 3 weeks of hypoxia (10% oxygen). At week 5 post-injection, the PAH rats were randomized to Macitentan (30 mg/kg daily) treatment or no treatment. Substrate utilization was serially assessed 5 and 8 weeks post-injection with 2-[18F]fluoro 2-deoxyglucose (FDG) and 14(R,S)-[18F]fluoro-6-thia-heptadecanoic acid (FTHA) PET for glucose and fatty acid metabolism respectively and correlated with in vivo functional measurements. RESULTS: PAH induction resulted in a 2.5-fold increase in RV FDG uptake (standardized uptake value (SUV) of normal control: 1.6 +/- 0.4, week 5: 4.1 +/- 1.9, week 8: 4.0 +/- 1.6, P < 0.05 for all groups vs. control). RV FTHA showed twofold increased uptake at week 5 (SUV control: 1.50 +/- 0.39, week 5: 3.06 +/- 1.10, P = 0.03). Macitentan significantly decreased RV FDG uptake at 8 weeks (SUV: 2.5 +/- 0.9, P = 0.04), associated with improved RV ejection fraction and reduced RV systolic pressure, while FTHA uptake was maintained. CONCLUSION: PAH is associated with metabolic changes in the RV, characterized by a marked increase in FDG and FTHA uptake. Macitentan treatment reduced PAH severity and was associated with a decrease in RV FDG uptake and improved RV function. PMID- 27688038 TI - Angiomatosis of soft tissue as an important differential diagnosis for intramuscular venous malformations. AB - Background We aimed to improve management of extremity low-flow vascular malformations by analyzing the histology and imaging of venous malformations (VMs) not responsive to sclerotherapy. Method We reviewed patient records of 102 consecutive patients treated with sclerotherapy for extremity VM in our institution to identify patients who had undergone surgery due to insufficient response. We semi-quantitatively analysed the tissue specimens and compared histological findings to those in preoperative imaging. Result The number of patients operated on was 19 (18.6%); 15 of them had lower-extremity intramuscular lesions. The histological pattern of 13 of these 15 lesions corresponded to angiomatosis of soft tissue (AST). All other lesions treated surgically were VMs. The histology of AST was distinctive but magnetic resonance imaging findings often overlapped with those of VM. Conclusion AST is easily mixed with intramuscular VM. The differentiation of these two entities has therapeutic importance. We emphasize the role of histology in the differential diagnostics of intramuscular slow-flow vascular malformations. PMID- 27688039 TI - Colluvium supply in humid regions limits the frequency of storm-triggered landslides. AB - Shallow landslides, triggered by extreme rainfall, are a significant hazard in mountainous landscapes. The hazard posed by shallow landslides depends on the availability and strength of colluvial material in landslide source areas and the frequency and intensity of extreme rainfall events. Here we investigate how the time taken to accumulate colluvium affects landslide triggering rate in the Southern Appalachian Mountains, USA and how this may affect future landslide hazards. We calculated the failure potential of 283 hollows by comparing colluvium depths to the minimum (critical) soil depth required for landslide initiation in each hollow. Our data show that most hollow soil depths are close to their critical depth, with 62% of hollows having soils that are too thin to fail. Our results, supported by numerical modeling, reveal that landslide frequency in many humid landscapes may be insensitive to projected changes in the frequency of intense rainfall events. PMID- 27688040 TI - Role of NF-kbeta factor Rel2 during Plasmodium falciparum and bacterial infection in Anopheles dirus. AB - BACKGROUND: Anopheles mosquitoes transmit malaria which is one of the world's most threatening diseases. Anopheles dirus (sensu stricto) is among the main vectors of malaria in South East Asia. The mosquito innate immune response is the first line of defence against malaria parasites during its development. The immune deficiency (IMD) pathway, a conserved immune signaling pathway, influences anti-Plasmodium falciparum activity in Anopheles gambiae, An. stephensi and An. albimanus. The aim of the study was to determine the role of Rel2, an IMD pathway controlled NF-kappabeta transcription factor, in An. dirus. METHODS: RACE (Rapid amplification of cDNA ends) was performed on the Rel2 gene. Double-stranded Rel2 was constructed and injected into the thorax of female mosquitoes. The injected mosquitoes were fed on a P. falciparum gametocyte culture and dissected on day 7 9 post-feeding in order to count the oocysts. A survival analysis was conducted by exposing the dsRNA injected mosquitoes to Gram-positive and Gram-negative bacteria. RESULTS: This study demonstrated that the Rel2 gene in An. dirus has two isoforms, short length and full length. RNA interference-mediated gene silencing of Rel2 showed that the latter is involved in protection against P. falciparum, Gram-positive bacteria (Micrococcus luteus) with Lys-type peptidoglycan and Gram-negative bacteria (Escherichia coli) with DAP-type peptidoglycan. CONCLUSION: This study suggested that there are similarities in the splicing events and functionality of the Rel2 gene, between the Anopheles species. Among all the important anophelines, the immunity of only a few has been thoroughly investigated. In order to develop novel vector-based control strategies and restrict malaria transmission, the immune pathways of these important vectors should be thoroughly investigated. PMID- 27688041 TI - Orphan nuclear receptor SHP regulates iron metabolism through inhibition of BMP6 mediated hepcidin expression. AB - Small heterodimer partner (SHP) is a transcriptional corepressor regulating diverse metabolic processes. Here, we show that SHP acts as an intrinsic negative regulator of iron homeostasis. SHP-deficient mice maintained on a high-iron diet showed increased serum hepcidin levels, decreased expression of the iron exporter ferroportin as well as iron accumulation compared to WT mice. Conversely, overexpression of either SHP or AMP-activated protein kinase (AMPK), a metabolic sensor inducing SHP expression, suppressed BMP6-induced hepcidin expression. In addition, an inhibitory effect of AMPK activators metformin and AICAR on BMP6 mediated hepcidin gene expression was significantly attenuated by ablation of SHP expression. Interestingly, SHP physically interacted with SMAD1 and suppressed BMP6-mediated recruitment of the SMAD complex to the hepcidin gene promoter by inhibiting the formation of SMAD1 and SMAD4 complex. Finally, overexpression of SHP and metformin treatment of BMP6 stimulated mice substantially restored hepcidin expression and serum iron to baseline levels. These results reveal a previously unrecognized role for SHP in the transcriptional control of iron homeostasis. PMID- 27688042 TI - Proton Conducting Graphene Oxide/Chitosan Composite Electrolytes as Gate Dielectrics for New-Concept Devices. AB - New-concept devices featuring the characteristics of ultralow operation voltages and low fabrication cost have received increasing attention recently because they can supplement traditional Si-based electronics. Also, organic/inorganic composite systems can offer an attractive strategy to combine the merits of organic and inorganic materials into promising electronic devices. In this report, solution-processed graphene oxide/chitosan composite film was found to be an excellent proton conducting electrolyte with a high specific capacitance of ~3.2 MUF/cm2 at 1.0 Hz, and it was used to fabricate multi-gate electric double layer transistors. Dual-gate AND logic operation and two-terminal diode operation were realized in a single device. A two-terminal synaptic device was proposed, and some important synaptic behaviors were emulated, which is interesting for neuromorphic systems.

PMID- 27688043 TI - Evaluation of medicine retail outlets for sale of typhoid fever vaccine among adults in two urban and rural settings in western Kenya: a proof-of-concept study. AB - BACKGROUND: Private sector medicine outlets are an important provider of health services across the developing world, and are an untapped means of distributing and selling vaccines outside of childhood immunization programs. The present study assessed the viability of medicine outlets (chemists and pharmacies) as potential channels for sale of vaccines. METHODS: To evaluate the viability of the medicine outlet model, we partnered with nine outlets across urban and rural communities in western Kenya to sell a nurse-administered typhoid vaccine. Purchasers were surveyed to reveal market demographic characteristics, reasons for vaccine purchase, and sources of information about the program. Key informant interviews and focus group discussions defined acceptability, demand, and additional suggestions for improving this mechanism of selling and distributing vaccines. RESULTS: There was a higher than expected demand for the vaccine that resulted in stock-outs. Previous instance of typhoid, desire to prevent disease, affordable price and convenience were cited by most participants as main reasons for purchase of vaccine at the local outlet. The most common source of information on the vaccine sale was word-of-mouth and referral from friends. Longer vaccine sale duration, adequate stocking of vaccines and extended hours of administration in the evening to allow working individuals to buy vaccines were cited by participants as ways for improved participation in the future. CONCLUSIONS: This study demonstrated a high demand for vaccines at community medicine outlets. Important insights on how to improve and sustain such a program included extension of distribution time, education of outlet keepers, and minimizing vaccine stockouts. With improved social marketing, infrastructure mapping, education and pricing schemes, medicine outlets could become a sustainable avenue for selling adult vaccines in emerging markets for both routine and pandemic vaccines.

AB - Treatment of patients with multiple brain metastases using a single-isocenter volumetric modulated arc therapy (VMAT) has been shown to decrease treatment time with the tradeoff of larger low dose to the normal brain tissue. We have developed an efficient Projection Summing Optimization Algorithm to optimize the treatment geometry in order to reduce dose to normal brain tissue for radiosurgery of multiple metastases with single-isocenter VMAT. The algorithm: (a) measures coordinates of outer boundary points of each lesion to be treated using the Eclipse Scripting Application Programming Interface, (b) determines the rotations of couch, collimator, and gantry using three matrices about the cardinal axes, (c) projects the outer boundary points of the lesion on to Beam Eye View projection plane, (d) optimizes couch and collimator angles by selecting the least total unblocked area for each specific treatment arc, and (e) generates a treatment plan with the optimized angles. The results showed significant reduction in the mean dose and low dose volume to normal brain, while maintaining the similar treatment plan qualities on the thirteen patients treated previously. The algorithm has the flexibility with regard to the beam arrangements and can be integrated in the treatment planning system for clinical application directly.

Of the primary host-associated cues known to attract bed bugs - CO2, odors, heat - heat has received little attention as an independent stimulus. We evaluated the effects of target temperatures ranging from 23 to 48 degrees C on bed bug activation, orientation and feeding. Activation and orientation responses were assessed using a heated target in a circular arena. All targets heated above ambient temperature activated bed bugs (initiated movement) and elicited oriented movement toward the target, with higher temperatures generally resulting in faster activation and orientation. The distance over which bed bugs could orient toward a heat source was measured using a 2-choice T-maze assay. Positive thermotaxis was limited to distances <3 cm. Bed bug feeding responses on an artificial feeding system increased with feeder temperature up to 38 and 43 degrees C, and declined precipitously at 48 degrees C. In addition, bed bugs responded to the relative difference between ambient and feeder temperatures. These results highlight the wide range of temperatures that elicit activation, orientation and feeding responses in bed bugs. In contrast, the ability of bed bugs to correctly orient towards a heated target, independently of other cues, is limited to very short distances (<3 cm). Finally, bed bug feeding is shown to be relative to ambient temperature, not an absolute response to feeder blood temperature. PMID- 27688051 TI - Asymmetric energetic costs in reciprocal-cross hybrids between carnivorous mice (Onychomys). AB - Aerobic respiration is a fundamental physiological trait dependent on coordinated interactions between gene products of the mitochondrial and nuclear genomes. Mitonuclear mismatch in interspecific hybrids may contribute to reproductive isolation by inducing reduced viability (or even complete inviability) due to increased metabolic costs. However, few studies have tested for effects of mitonuclear mismatch on respiration at the whole-organism level. We explored how hybridization affects metabolic rate in closely related species of grasshopper mice (genus Onychomys) to better understand the role of metabolic costs in reproductive isolation. We measured metabolic rate across a range of temperatures to calculate basal metabolic rate (BMR) and cold-induced metabolic rate (MRc) in O. leucogaster, O. torridus and O. arenicola, and in reciprocal F1 hybrids between the latter two species. Within the genus, we found a negative correlation between mass-specific BMR and body mass. Although O. arenicola was smaller than O. torridus, hybrids from both directions of the cross resembled O. arenicola in body mass. In contrast, hybrid BMR was strongly influenced by the direction of the cross: reciprocal F1 hybrids were different from each other but indistinguishable from the maternal species. In addition, MRc was not significantly different between hybrids and either parental species. These patterns indicate that metabolic costs are not increased in Onychomys F1 hybrids and, while exposure of incompatibilities in F2 hybrids cannot be ruled out, suggest that mitonuclear mismatch does not act as a primary barrier to gene flow. Maternal matching of BMR is suggestive of a strong effect of mitochondrial genotype on metabolism in hybrids. Together, our findings provide insight into the metabolic consequences of hybridization, a topic that is understudied in mammals. PMID- 27688052 TI - Speed-dependent interplay between local pattern-generating activity and sensory signals during walking in Drosophila. AB - In insects, the coordinated motor output required for walking is based on the interaction between local pattern-generating networks providing basic rhythmicity and leg sensory signals, which modulate this output on a cycle-to-cycle basis. How this interplay changes speed-dependently and thereby gives rise to the different coordination patterns observed at different speeds is not sufficiently understood. Here, we used amputation to reduce sensory signals in single legs and decouple them mechanically during walking in Drosophila. This allowed for the dissociation between locally generated motor output in the stump and coordinating influences from intact legs. Leg stumps were still rhythmically active during walking. Although the oscillatory frequency in intact legs was dependent on walking speed, stumps showed a high and relatively constant oscillation frequency at all walking speeds. At low walking speeds we found no strict cycle-to-cycle coupling between stumps and intact legs. In contrast, at high walking speeds stump oscillations were strongly coupled to the movement of intact legs on a one to-one basis. Although during slow walking there was no preferred phase between stumps and intact legs, we nevertheless found a preferred time interval between touch-down or lift-off events in intact legs and levation or depression of stumps. Based on these findings, we hypothesize that, as in other insects, walking speed in Drosophila is predominantly controlled by indirect mechanisms and that direct modulation of basic pattern-generating circuits plays a subsidiary role. Furthermore, inter-leg coordination strength seems to be speed dependent and greater coordination is evident at higher walking speeds. PMID- 27688053 TI - Unique magnetostriction of Fe68.8Pd31.2 attributable to twinning. AB - Fe68.8Pd31.2 exhibits an anomalously large magnetostriction of ~400 ppm at room temperature as well as linear, isotropic, and hysteresis free magnetization behavior. This near perfectly reversible magnetic response is attributable to the presence of a large number of premartensitic magnetoelastic twin clusters present in the system made possible through the elastic softening that occurs near a martensitic transformation temperature of 252 K. It is proposed that the twin clusters in the material reduce both internal elastic and magnetic energy, causing the elastic and magnetic behavior of the material to be intimately linked. In such a framework, the anisotropy energy becomes extremely low causing the material to bear no crystalline dependence on magnetization, and application of a magnetic field causes simultaneous magnetic and twin domain movement which relaxes the system. PMID- 27688054 TI - Detecting reproductive system abnormalities of broiler breeder roosters at different ages. AB - The objective of this study was to detect the reasons of rooster's fertility decrease at 50 weeks of age. Therefore, the reproductive system of broiler breeder roosters was laparoscopic, macroscopic and histopathology evaluated, and a comparison of the anatomical aspect with the sperm analysis and birds' age was realized. Cobb roosters (n = 59) were distributed into two groups (30 and 50 weeks). Evaluations were performed with laparoscopy, macroscopy and histopathology, and seminal quality, blood serum testosterone concentration and weight were also determined. The old roosters presented smaller testicle size, higher intensity epididymal lithiasis and lower testicle sperm production, compared to the young roosters. The use of the endoscope could easily distinguish a normal-sized testicle than an atrophic one. Four old roosters with severe testicular atrophy did not show spermatogenesis, although three still had sperm in the ejaculate. This would falsely indicate a wrong diagnosis of normal fertility before the testicular atrophy took place. In conclusion, in addition to the weight increase with age, the testicular atrophy and impairment of sperm production seemed to be the main reason to the decrease in the rooster's fertility at 50 weeks of age. Therefore, the use of the laparoscopy as a way to detect the roosters with testicular atrophy before 50 weeks of age and their removal from them flock could be useful as a diagnostic tool to prevent the birds' fertility loss. PMID- 27688055 TI - Proteomic analysis of pear (Pyrus pyrifolia) ripening process provides new evidence for the sugar/acid metabolism difference between core and mesocarp. AB - Pears are one of the most popular nutrient-rich fruits in the world. The pear core and mesocarp have significantly different metabolism, although they display similar profiles. Most strikingly, the core is more acidic in taste. Our results showed that there is more titrated acid but lower total soluble solids in the core compared to the mesocarp, and the content of citric acid was more than 17 fold higher in the core compared to the mesocarp at the ripening stage. Proteomics was used to investigate the difference between core and mesocarp tissues during "Cuiguan" pear ripening. Fifty-four different protein expression patterns were identified in the core and mesocarp. In general, common variably expressed proteins between the core and mesocarp were associated with important physiological processes, such as glycolysis, pyruvate metabolic processes, and oxidative stress. Further, protein level associated qRT-PCR verification revealed a higher abundance of fructose-bisphosphate aldolase and NADP-dependent malic enzymes, which may play a role in the low acid content in the mesocarp, whereas a higher abundance of disulfide isomerase-like 2-2 and calcium-dependent lipid binding in the core may explain why it is less prone to accumulate sugar. The different levels of a few typical ROS scavenger enzymes suggested that oxidative stress is higher in the core than in the mesocarp. This study provides the first characterization of the pear core proteome and a description of its variation compared to the mesocarp during ripening. PMID- 27688056 TI - Health game interventions to enhance physical activity self-efficacy of children: a quantitative systematic review. AB - AIM: To describe and explore health game interventions that enhance the physical activity self-efficacy of children and to evaluate the effectiveness of these interventions. BACKGROUND: Physical inactivity among children has increased globally. Self-efficacy is one of the key determinants of physical activity engagement in children. There is a need to explore new and innovative interventions to enhance physical activity self-efficacy that are also acceptable for today's children. DESIGN: Quantitative systematic review. DATA SOURCES: MEDLINE (Ovid), CINAHL, PsychInfo, EMBASE and the Cochrane Library between 1996 2016. REVIEW METHODS: A review was conducted in accordance with the Cochrane Collaboration guidelines. A systematic search was done in June 2016 by two independent reviewers according to the eligibility criteria as follows: controlled trial, comparison of digital game intervention with no game intervention control condition, participants younger than 18 years of age and reported statistical analyses of a physical activity self-efficacy outcome measure. RESULTS: Altogether, five studies met the eligibility criteria. Four game interventions, employing three active games and one educational game, had positive effects on children's physical activity self-efficacy. An intervention, employing a game-themed mobile application, showed no intervention effects. The variation between intervention characteristics was significant and the quality of the studies was found to be at a medium level. CONCLUSION: Although health game interventions seemingly enhance the physical activity self-efficacy of children and have potential as a means of increasing physical activity, more rigorous research is needed to clarify how effective such interventions are in the longer run to contribute to the development of game-based interventions. PMID- 27688058 TI - Current insights into the sulfatase pathway in human testis and cultured Sertoli cells. AB - Within the human testis, large amounts of sulfated steroid hormones are produced. As shown in breast tissue and placenta, these might not only be excretion intermediates, but re-activated in target cells by steroid sulfatase (STS). This process is called sulfatase pathway and may play a pivotal role in para- and/or intracrine regulation by creating a local supply for steroid hormones. This requires a facilitated transport via uptake carriers and efflux transporters as these hydrophilic molecules cannot pass the cell membrane. Moreover, blood-testis barrier formation in the testis requires a transport through Sertoli cells (SCs) to reach germ cells (GCs). Sertoli cells are therefore expected to play a key role as gate-keepers for sulfatase pathway in human seminiferous epithelium. We analyzed the mRNA and protein expression of uptake carriers and efflux transporters like organic anion-transporting polypeptides (OATP2B1, OATP3A1) and multidrug resistance-related proteins (MRP1, MRP4) in testicular tissue and cultured Sertoli cells (FS1, HSEC). Additionally, expression pattern of STS as well as sulfonating enzymes (SULTs) were assessed. OATP2B1, OATP3A1 and STS were detected in SCs as well as GCs, whereas MRP1 is only expressed in SCs, and SULT1E1 only in Leydig cells, respectively. By transcellular transport of [H3]DHEAS in HSEC, we showed a functional transport of sulfated steroids in vitro. Our data indicate that steroid synthesis via sulfatase pathway in Sertoli cells in vivo and in vitro is possible and may contribute to paracrine and intracrine regulation employing the local supply of sulfated and free steroid hormones inside seminiferous tubules.

AB - In the nineteenth century, there was a dispute about the existence of a lung alveolar epithelium which remained unsolved until the invention of electron microscopy (EM) and its application to the lung. From the early 1960s, Ewald Weibel became the master of lung EM. He showed that the alveolar epithelium is covered with a lining layer containing surfactant. Weibel also explained the phenomenon of "non-nucleated plates" observed already in 1881 by Albert Kolliker. Weibel's most significant contribution was to the development of stereological methods. Therefore, quantitative characterization of lung structure revealing structure-function relationships became possible. Today, the spectrum of EM methods to study the fine structure of the lung has been extended significantly. Cryo-preparation techniques are available which are necessary for immunogold labeling of molecules. Energy-filtering techniques can be used for the detection of elements. There have also been major improvements in stereology, thus providing a very versatile toolbox for quantitative lung phenotype analyses. A new dimension was added by 3D EM techniques. Depending on the desired sample size and resolution, the spectrum ranges from array tomography via serial block face scanning EM and focused ion beam scanning EM to electron tomography. These 3D datasets provide new insights into lung ultrastructure. Biomedical EM is an ever developing field. Its high resolution remains unparalleled. Moreover, EM has the unique advantage of providing an "open view" into cells and tissues within their full architectural context. Therefore, EM will remain an indispensable tool for a better understanding of the lung's functional design. PMID- 27688062 TI - The spaghetti sign. PMID- 27688061 TI - Microwave ablation for hepatocellular carcinoma associated with Budd-Chiari syndrome after transarterial chemoembolization: an analysis of ten cases. AB - PURPOSE: To evaluate the feasibility, efficacy, and safety of microwave ablation (MWA) in the treatment of hepatocellular carcinoma associated with Budd-Chiari syndrome (BCS) after transarterial chemoembolization (TACE). METHODS: A total of 10 patients (mean 50.0 +/- 7.5 years) with 15 BCS-associated HCC lesions were retrospectively evaluated. All patients received MWA treatment for residual tumors after 1 to 3 sessions of TACE. The diagnosis of residual tumors was confirmed by at least two types of enhanced imaging. CEUS images were performed to confirm the residual lesions and guide the placement of antenna before MWA. Thermal monitoring and artificial pleural effusion or ascites were used to guarantee ablative accuracy and safety for patients with tumors adjacent to vital structures. Technical success, technique efficacy, local tumor progression, survival rate, and the incidence of complications were comprehensively analyzed. RESULTS: Technical success and technique effectiveness were achieved in all patients. Thirteen lesions achieved complete ablation for the first time, and 2 lesions needed two sessions. Thermal monitoring was used in 2 patients, artificial pleural effusion was used in 1 patient, and artificial ascites in 2 patients. In a median follow-up of 34.5 months (range 21-52 months), no LTP was founded in all patients. Intrahepatic recurrence was found in 5 patients. 1-, 2-, 3-, and 4-year survival rates were 100%, 100%, 74.1%, and 37.0%, respectively. No major or minor complications were observed. CONCLUSION: Microwave ablation is a feasible and effective way to treat residual tumors after TACE treatment in patients with BCS-associated HCC.

PMID- 27688063 TI - Agreement between region-of-interest- and parametric map-based hepatic proton density fat fraction estimation in adults with chronic liver disease. AB - PURPOSE: To compare agreement between region-of-interest (ROI)- and parametric map-based methods of hepatic proton density fat fraction (PDFF) estimation in adults with known or suspected hepatic steatosis secondary to chronic liver disease over a range of imaging and analysis conditions. MATERIALS AND METHODS: In this IRB approved HIPAA compliant prospective single-site study, 31 adults with chronic liver disease undergoing clinical gadoxetic acid-enhanced liver magnetic resonance imaging at 3 T were recruited. Multi-echo gradient-echo imaging at flip angles of 10 degrees and 50 degrees was performed before and after administration of gadoxetic acid. Six echoes were acquired at successive nominally out-of-phase and in-phase echo times. PDFF was estimated with a nonlinear fitting algorithm using the first two, three, four, five, and (all) six echoes. Hence, 20 different imaging and analysis conditions were used (pre/post contrast x low/high flip angle x 2/3/4/5/6 echoes). For each condition, PDFF estimation was done in corresponding liver locations using two methods: a region of-interest (ROI)-based method in which mean signal intensity values within ROIs were run through the fitting algorithm, and a parametric map-based method in which individual signal intensities were run through the fitting algorithm pixel by pixel. Agreement between ROI- and map-based PDFF estimation was assessed by Bland-Altman and intraclass correlation (ICC) analysis. RESULTS: Depending on the condition and method, PDFF ranged from -2.52% to 45.57%. Over all conditions, mean differences between ROI- and map-based PDFF estimates ranged from 0.04% to 0.24%, with all ICCs >=0.999. CONCLUSION: Agreement between ROI- and parametric map-based PDFF estimation is excellent over a wide range of imaging and analysis conditions. PMID- 27688066 TI - Synthesis of Water Dispersible Fluorescent Carbon Nanocrystals from Syzygium cumini Fruits for the Detection of Fe3+ Ion in Water and Biological Samples and Imaging of Fusarium avenaceum Cells. AB - In this work, water dispersible fluorescent carbon nanocrystals (NCs) were synthesized by a simple, green and low cost hydrothermal method using Syzygium cumini (jamun) as a carbon source at 180 degrees C for 6 h. The average size of carbon NCs was found to be 2.1 +/- 0.5 nm and shown bright blue fluorescence when excited at 365 nm under UV lamp. The carbon NCs were characterized by spectroscopic (UV-visible and fluorescence, Fourier transform infrared and dynamic light scattering) and high resolution transmission electron microscopic techniques. The quantum yield of carbon NCs was found to be ~5.9 % at 438 nm emission wavelength when excited at 360 nm. It was noticed that none of the metal ions quenched the fluorescence intensity of carbon NCs at 438 nm except for Fe3+, indicating the formation of Fe3+ ion-carbon NCs complexes. The linear range was observed in the concentration range of 0.01-100 MUM with the corresponding detection limits of 0.001 MUM, respectively. Furthermore, the carbon NCs were used as probes for imaging of fungal (Fusarium avenaceum) cells. PMID- 27688067 TI - The prevalence of chronic peri-pouch sepsis in patients treated for antibiotic dependent or refractory primary idiopathic pouchitis. AB - AIM: Chronic peri-pouch sepsis (CPPS) may be mistaken for antibiotic-dependent or refractory primary idiopathic pouchitis (ADRP), but requires different treatment such as drainage. The study aimed to identify the prevalence of CPPS in patients thought to have ADRP. The secondary aims were to identify any specific features on pouchoscopy suggesting CPPS and to determine the results of treatment for CPPS. METHOD: The records of patients who had been treated for ADRP between March 2006 and June 2015 were reviewed retrospectively. Only those with endoscopic evidence of pouch inflammation who had also undergone MRI of the pelvis were included. The findings on pouchoscopy and the outcome of treatment were determined. RESULTS: Sixty-eight patients (43 men, 63%) were identified with apparent ADRP between March 2006 and June 2015. MRI of the pelvis showed CPPS in 26 (38%). In those with CPPS, the inflammation was more often located in the upper pouch alone (15%) compared with patients without CPPS (0%) (P = 0.0184). Examination under anaesthesia was performed in 13 of those with CPPS. In five a collection was identified and drained; symptoms improved in only one (4%). Eighteen patients (69%) remained on antibiotics and seven (27%) had a defunctioning stoma or underwent pouch excision. CONCLUSION: In patients thought to have ADRP, 38% had CPPS on MRI. There was no clinically relevant specific feature on pouchoscopy suggestive of CPPS. The possibility of CPPS should be considered early in patients with apparent ADRP and pelvic MRI performed. This might lead to earlier detection of CPPS and appropriate treatment. PMID- 27688068 TI - Static magnetic fields enhance dental pulp stem cell proliferation by activating the p38 mitogen-activated protein kinase pathway as its putative mechanism. AB - Dental pulp stem cells (DPSCs) can be a potential stem cell resource for clinical cell therapy and tissue engineering. However, obtaining a sufficient number of DPSCs for repairing defects is still an issue in clinical applications. Static magnetic fields (SMFs) enhance the proliferation of several cell types. Whether or not SMFs have a positive effect on DPSC proliferation is unknown. Therefore, the aim of this study was to investigate the effect of SMFs on DPSC proliferation and its possible intracellular mechanism of action. For methodology, isolated DPSCs were cultured with a 0.4-T SMF. Anisotropy of the lipid bilayer was examined using a fluorescence polarization-depolarization assay. The intracellular calcium ions of the SMF-treated cells were analysed using Fura-2 acetoxymethyl ester labelling. The cytoskeletons of exposed and unexposed control cells were labelled with actin fluorescence dyes. Cell viability was checked when the tested cells were cultured with inhibitors of ERK, JNK and p38 to discern the possible signalling cascade involved in the proliferative effect of the SMF on the DPSCs. Our results showed that SMF-treated cells demonstrated a higher proliferation rate and anisotropy value. The intracellular calcium ions were activated by SMFs. In addition, fluorescence microscopy images demonstrated that SMF-treated cells exhibit higher fluorescence intensity of the actin cytoskeletal structure. Cell viability and real-time polymerase chain reaction suggested that the p38 signalling cascade was activated when the DPSCs were exposed to a 0.4-T SMF. F-actin intensity tests showed that SB203580-treated cells decreased even with SMF exposure. Additionally, the F-/G-actin ratio increased due to slowing of the cytoskeleton reorganization by p38 mitogen-activated protein kinase inhibition. According to these results, we suggest that a 0.4-T SMF affected the cellular membranes of the DPSCs and activated intracellular calcium ions. This effect may activate p38 mitogen-activated protein kinase signalling, and thus reorganize the cytoskeleton, which contributes to the increased cell proliferation of the DPSCs.

AB - BACKGROUND: Early detection of fetal alcohol spectrum disorders (FASDs) is desirable to allow earlier and more comprehensive interventions to be initiated for the mother and infant. We examined prenatal ultrasound as an early method of detecting markers of the physical features and neurobehavioral deficits characteristic of FASD. METHODS: A longitudinal cohort of pregnant women in Ukraine was recruited as part of the Collaborative Initiative on Fetal Alcohol Spectrum Disorders. Women were enrolled into a moderately to heavy-alcohol exposed group or a low- or no-alcohol exposure group and were followed to pregnancy outcome. In the second trimester, a fetal ultrasound was performed to measure transverse cerebellar diameter, occipital frontal diameter (OFD), caval calvarial distance, frontothalamic distance (FTD), interorbital distance (IOD), outer orbital diameter, and orbital diameter (OD). Live born infants received a dysmorphological examination and a neurobehavioral evaluation using the Bayley Scales of Infant Development. These data were used to classify infants with respect to FASD. Comparisons were made on the ultrasound measures between those with and without features of FASD, adjusting for gestational age at ultrasound and maternal smoking. RESULTS: A total of 233 mother/child dyads were included. Children classified as FASD had significantly longer IOD and lower FTD/IOD, OFD/IOD, and FTD/OD ratios (p < 0.05). Children with a Bayley score <85 had significantly shorter FTD, longer IOD, lower OFD/IOD, and FTD/IOD ratios (p < 0.05). In general, mean differences were small. Ultrasound variables alone predicted <10% of the variance in the FASD outcome. CONCLUSIONS: Some ultrasound measurements were associated with FASD, selected facial features of the disorder, and lower neurobehavioral scores. However, mean differences were relatively small, making it difficult to predict affected children based solely on these measures. It may be advantageous to combine these easily obtained ultrasound measures with other data to aid in identifying high risk for an FASD outcome. PMID- 27688070 TI - A supervised weighted similarity measure for gene expressions using biological knowledge. AB - A supervised similarity measure for Saccharomyces cerevisiae gene expressions is developed which can capture the gene similarity when multiple types of experimental conditions like cell cycle, heat shock are available for all the genes. The measure is called Weighted Pearson correlation (WPC), where the weights are systematically determined for each type of experiment by maximizing the positive predictive value for gene pairs having Pearson correlation greater than 0.80. The positive predictive value is computed by using the annotation information available from yeast GO-Slim process annotations in Saccharomyces Genome Database (SGD). Genes are then clustered by k-medoid algorithm using the newly computed WPC, and functions of 135 unclassified genes are predicted with a p-value cutoff 10-5 using Munich Information for Protein Sequences (MIPS) annotations. Out of these genes, functional categories of 55 gene are predicted with p-value cutoff greater than 10-10 and reported in this investigation. The superiority of WPC as compared to some existing similarity measures like Pearson correlation and Euclidean distance is demonstrated using positive predictive (PPV) values of gene pairs for different Saccharomyces cerevisiae data sets. The related code is available at http://www.sampa.droppages.com/WPC.html. PMID- 27688071 TI - Transcriptional regulation analysis of FAM3A gene and its effect on adipocyte differentiation. AB - FAM3A (family with sequence similarity 3, member A) is regulated by PPARG and participates in the metabolism of lipid in liver. However, the transcriptional regulation analysis of FAM3A is very little and biological function of FAM3A still unclear. In this study, the core promoter region and transcription factor binding sites of FAM3A gene were identified and characterized using dual luciferase report experiments and electrophoretic mobility shift assays (EMSA). The promoter activity of FAM3A was dramatically decreased after the mutation of C/EBPbeta binding sites, suggesting that C/EBPbeta is a transcriptional activator of FAM3A. Overexpression of FAM3A significantly inhibited the efficiency of preadipocytes to differentiate into adipocytes as indicated by Western Blot and Oil Red O staining assay. These results suggest that C/EBPbeta plays an important role in regulating FAM3A promoter activity and FAM3A inhibits adipocyte differentiation. PMID- 27688072 TI - Treatment of prostate cancer cells with S-adenosylmethionine leads to genome-wide alterations in transcription profiles. AB - The hypomethylation of DNA may support tumor progression; however, the mechanism underlying this relationship is not clear. Several studies have demonstrated that the in vitro application of the methyl donor S-adenosylmethionine (SAM) leads to promoter remethylation and the downregulation of proto-oncogene expression in cancer cells. It is not clear if this represents a general mechanism of SAM or is limited to selected genes. We examined this problem using new bisulfite sequencing and transcriptomic technologies. Treatment with SAM caused the downregulation of proliferation, migration, and invasion of prostate cancer (PC 3) cells. RNA sequencing revealed the genome-wide downregulation of genes involved in proliferation, migration, invasion, and angiogenesis. Real-time PCR of a subset of the genes confirmed these results. Reduced representation bisulfite sequencing (RRBS) displayed only minor differential methylation between treated cells and controls. In summary, we confirmed the anti-proliferative and anti-invasive effects of SAM. Additionally, we observed anti-migratory effects and downregulation of genes, especially those related to cancerogenesis. For some of the related genes, this is the first reported evidence of an association with prostate cancer. However, genome-wide modifications in methylation profiles were not observed by RRBS; thus, they are obviously not a major cause of alteration in transcription profiles and anti-cancer effects. PMID- 27688073 TI - Identification of genes in the hypothalamus-pituitary-gonad axis in the brain of Amur sturgeons (Acipenser schrenckii) by comparative transcriptome analysis in relation to kisspeptin treatment. AB - Kisspeptin plays an important role in the reproduction and onset of puberty in vertebrates through stimulation of gonadotropin-releasing hormone (GnRH). However, the mechanisms whereby kisspeptin-related genes regulate sexual differentiation in teleosts are poorly understood. We aimed to study the relationship between the hypothalamus-pituitary-gonad (HPG) axis and sexual differentiation in relation to kisspeptin in the sturgeon Acipenser schrenckii. We performed comparative transcriptomic analysis of the brains of sturgeons treated with KISS1-10 during the gonadal sex-differentiation-sensitive period (170-210days post-hatching (dph)) using an Illumina sequencing platform. We also analyzed mRNA expression levels of genes in the HPG axis using real-time quantitative polymerase chain reaction, and measured estradiol-17beta (E2) and testosterone (T) levels in the brain and gonads using radioimmunological methods. A total of 75,960 and 74,907 unigenes were produced from Kisspeptin-treated and physiological saline-treated fish, respectively, among which 47,891 genes were matched to the non-redundant nr database. Potential genes and their functions were identified by GO (32,435), KEGG (37,619), and COG analyses (18,502). A total of 3169 unigenes were differentially expressed between transcriptomes in KISS1-10 and saline-injected fish, including 300 up-regulated and 2869 down-regulated unigenes. Gene expression levels of KISS1, G protein-coupled receptor-54, GnRH, androgen receptor, estrogen receptor, and Cyp19a in the brain and gonad were significantly affected by KISS1-10 treatment. KISS1-10 injection also significantly increased brain levels of E2 and T, compared with controls. These results support important roles for KISS1 in the regulation of the HPG axis, and in sex differentiation and reproduction in the Amur sturgeon. PMID- 27688074 TI - Differential protection by cell wall components of Lactobacillus amylovorus DSM 16698Tagainst alterations of membrane barrier and NF-kB activation induced by enterotoxigenic F4+ Escherichia coli on intestinal cells. AB - BACKGROUND: The role of Lactobacillus cell wall components in the protection against pathogen infection in the gut is still largely unexplored. We have previously shown that L. amylovorus DSM 16698T is able to reduce the enterotoxigenic F4+ Escherichia coli (ETEC) adhesion and prevent the pathogen induced membrane barrier disruption through the regulation of IL-10 and IL-8 expression in intestinal cells. We have also demonstrated that L. amylovorus DSM 16698T protects host cells through the inhibition of NF-kB signaling. In the present study, we investigated the role of L. amylovorus DSM 16698T cell wall components in the protection against F4+ETEC infection using the intestinal Caco 2 cell line. METHODS: Purified cell wall fragments (CWF) from L. amylovorus DSM 16698T were used either as such (uncoated, U-CWF) or coated with S-layer proteins (S-CWF). Differentiated Caco-2/TC7 cells on Transwell filters were infected with F4+ETEC, treated with S-CWF or U-CWF, co-treated with S-CWF or U-CWF and F4+ETEC for 2.5 h, or pre-treated with S-CWF or U-CWF for 1 h before F4+ETEC addition. Tight junction (TJ) and adherens junction (AJ) proteins were analyzed by immunofluorescence and Western blot. Membrane permeability was determined by phenol red passage. Phosphorylated p65-NF-kB was measured by Western blot. RESULTS: We showed that both the pre-treatment with S-CWF and the co- treatment of S-CWF with the pathogen protected the cells from F4+ETEC induced TJ and AJ injury, increased membrane permeability and activation of NF-kB expression. Moreover, the U-CWF pre-treatment, but not the co-treatment with F4+ETEC, inhibited membrane damage and prevented NF-kB activation. CONCLUSIONS: The results indicate that the various components of L. amylovorus DSM 16698T cell wall may counteract the damage caused by F4+ETEC through different mechanisms. S layer proteins are essential for maintaining membrane barrier function and for mounting an anti-inflammatory response against F4+ETEC infection. U-CWF are not able to defend the cells when they are infected with F4+ETEC but may activate protective mechanisms before pathogen infection.

AB - A genome-wide methylation study was conducted among a sample of 114 infants (M age = 13.2 months, SD = 1.08) of low-income urban women with (n = 73) and without (n = 41) major depressive disorder. The Illumina HumanMethylation450 BeadChip array with a GenomeStudio Methylation Module and Illumina Custom model were used to conduct differential methylation analyses. Using the 5.0 * 10-7 p value, 2,119 loci were found to be significantly different between infants of depressed and nondepressed mothers. Infants of depressed mothers had greater methylation at low methylation sites (0%-29%) compared to infants of nondepressed mothers. At high levels of methylation (70%-100%), the infants of depressed mothers were predominantly hypomethylated. The mean difference in methylation between the infants of depressed and infants of nondepressed mothers was 5.23%. Disease by biomarker analyses were also conducted using GeneGo MetaCore Software. The results indicated significant cancer-related differences in biomarker networks such as prostatic neoplasms, ovarian and breast neoplasms, and colonic neoplasms. The results of a process networks analysis indicated significant differences in process networks associated with neuronal development and central nervous system functioning, as well as cardiac development between infants of depressed and nondepressed mothers. These findings indicate that early in development, infants of mothers with major depressive disorder evince epigenetic differences relative to infants of well mothers that suggest risk for later adverse health outcomes. PMID- 27688076 TI - Event-triggered reliable Hinfinity filter design for networked systems with multiple sensor distortions: A probabilistic partition approach. AB - In this paper, the problem of event-triggered reliable Hinfinity filtering for networked systems with multiple sensor distortions is investigated. The interval of sensor distortion in each channel is partitioned several segments. By introducing a set of rand variables, the model of multiple sensor distortions with their information of probability distribution in each segment is established, which is more general than the one in open results. Furthermore, an event-triggered communication scheme is proposed to mitigate the utility of limited network bandwidth. Then a unified model with consideration of the event triggered communication scheme and the sensor distortion is put forward. Based on this model, sufficient conditions of the mean square stability of the filtering error system and Hinfinity filter parameters are achieved. Finally, a simulation example is exploited to demonstrate the effectiveness of the presented method. PMID- 27688077 TI - Reinnervation of rat endometrium in the anterior eye chamber model of experimental endometriosis: Old methods for new questions. AB - Endometriosis is a benign estrogen-dependent chronic gynecological disease characterized by the presence of endometrial-like tissue outside the uterine cavity. In both women and experimental endometriotic rats, endometriosis lesions endow autonomic and sensory nerves, which are thought to contribute to the disease-associated pain. Some evidence indicates that the reinnervation of lesions is regulated by factors produced by the endometrial tissue as well as by environmental factors from the peritoneum. In this study, we examined the reinnervation of the rat endometrial tissue in an ectopic environment different from the peritoneum employing the anterior eye chamber model of experimental endometriosis. At 3 and 6weeks following transplantation, endometrial grafts retained many histological features of the eutopic tissue. Both sympathetic and sensory nerves reinnervated endometrial grafts and distributed in the stroma-like tissue, around blood vessels and in close proximity to the glands and lining epithelium. Sympathetic innervation was more robust than sensory innervation. No significant topographical relationship between sympathetic nerves and macrophages was observed. These results suggest that the rat endometrium possesses intrinsic neuritogenic capacities and can be reinnervated by sympathetic and sensory nerves in ectopic sites different from the peritoneum. PMID- 27688079 TI - Sarcomatoid Adrenal Carcinoma: Case Report with Contribution to Pathogenesis. AB - A tumor in the adrenal region with two metastases in the liver was classified as poorly differentiated sarcoma on the base of extensive immunostainings (expression of vimentin, desmin, myogenin, and CD31, no expression of inhibin, melan A). Four years later in a second examination with molecular methods for a study of adrenal sarcomas, this diagnosis must be revised due to the lack of MDM 2 gene amplification and FKHR translocation which exclude sarcoma. Further immunostainings of many other parts of the tumor showed in one area more mature tumor tissue expressing synaptophysin, SF-1, and melan A. From these findings we classified an adrenal cortical cancer with predominant dedifferentiation into a sarcomatoid adrenal carcinoma. The properties of this very rare cancer type are presented and discussed. PMID- 27688078 TI - DNA vaccine encoding central conserved region of G protein induces Th1 predominant immune response and protection from RSV infection in mice. AB - Human respiratory syncytial virus (RSV) can cause serious infection in the lower respiratory tract, especially in infants, young children, the elderly and the immunocompromised population worldwide. Previous study demonstrated the polypeptide (amino acids 148-198) of RSV attachment (G) glycoprotein, corresponding to the central conserved region and encompassing CX3C chemokine motif, could induce antibodies and protection from RSV challenge in mice [1,2]. In this study, we evaluated the immune efficacy of the recombinant DNA vaccine of pVAX1/3G148-198 encoding RSV G protein polypeptide. RSV specific serum IgG antibodies with neutralizing activity were stimulated following prime-boost immunization of pVAX1/3G148-198 intramuscularly, and the ratio of IgG2a/IgG1 was 4.93, indicating a Th1 biased immune response. After challenged intranasally with RSV Long, the vaccinated mice showed both decreased lung RSV titers, pulmonary inflammation and body weight loss. The results suggest that pVAX1/3G148-198 DNA vaccine may be an effective RSV vaccine candidate, and deserves further exploration. PMID- 27688080 TI - Reliability of Ki-67 Determination in FNA Samples for Grading Pancreatic Neuroendocrine Tumors. AB - Neuroendocrine pancreatic tumors (PanNETs) are graded on the basis of their proliferative activity. Cytological samples are commonly the only samples available, but the determination of Ki-67 in cytology and its reliability as a measure of tumor mitotic activity is not well settled. We have retrospectively reviewed all the cases of FNA under EUS control of PanNETs in a 10-year period (2006-2016) in the Hospital Clinico San Carlos (Madrid). We identified 10 PanNET cases with histological correlation. Median age was 49.4 years and the patients were mainly women. PanNETs were located more frequently in the tail of the pancreas, with a median size of 33.8 mm. None of our cases was a grade 3 tumor. The seven grade 1 tumors confirmed in histology had consistent Ki-67 in cytology. In three cases (30 %), there were discrepancies between the Ki-67 index measured in cytology and histology, and the differences ranged from 2 to 15 %; all these cases were grade 2 tumors in histology and were graded as grade 1 tumors in FNA material. Our results are consistent with previous studies which showed understaging when tumor grade was assessed in cytological samples, mainly in G2 tumors. Previous literature has shown that Ki-67 assessment in EUS-FNA samples is a useful tool to rule out G3 tumors, but can be problematic for distinguishing G1 and G2 tumors.

AB - The cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) is a rare thyroid neoplasm characterized by unique morphologic findings and association with familial adenomatous polyposis. The biologic behavior of this variant has been reported to behave similarly to classic PTC. We report a rare sporadic case of CMV-PTC occurring in a 45-year-old female with multiple lymph nodes and bone metastases, which were detected after total thyroidectomy and radioactive iodine remnant ablation. Molecular analyses of primary thyroid and metastatic tumor tissues revealed a telomerase reverse transcriptase (TERT) promoter mutation, but absence of BRAF, KRAS, NRAS, HRAS, and PIK3CA mutations. Over a 4-year follow-up period, structurally identifiable bone metastases were persistent, but serial post-operative serum thyroglobulin levels remained undetectable in the absence of thyroglobulin antibody. The literature was reviewed. This is the first case of aggressive CMV-PTC showing TERT promoter mutation. TERT promoter mutations may help in predicting aggressive clinical behavior in CMV-PTC. Postoperative serum thyroglobulin measurement may have no impact on clinical decision-making in this type of tumor. PMID- 27688083 TI - Leptin and leptin receptors in salivary glands of primary Sjogren's syndrome. AB - BACKGROUND: The role of leptin in primary Sjogren's syndrome (SS) pathogenesis is unknown. The aim of this study was to investigate the expression of leptin and leptin receptor (LEPR) in minor salivary glands in patients with SS. MATERIALS AND METHODS: The expression of leptin and LEPR in minor salivary gland specimens obtained from patients with primary SS (n=50) and control subjects (n=50) were examined using immunohistochemical staining. RESULTS: Acinar cells, epithelial cells and adipocytes in salivary glands can express leptin and LEPR. It was observed that there was intense staining in the focal lymphocytic infiltration areas in SS patients. The intensity of leptin and LEPR staining under microscopy (400*) were graded semiquantitatively as negative, mild, moderate or strongly positive, and scored as 1, 2 or 3, respectively. The expression levels of leptin and LEPR in patients with primary SS were not higher than in controls. There was no significant difference in degrees of leptin and LEPR staining, staining intensity, and immunoreactive scores between groups. The expression of leptin and LEPR were not correlated with autoantibodies such as RF, ANA, anti-Ro, and/or anti-La positivity. CONCLUSIONS: These findings indicate that leptin and its receptors do not play an important role in primary SS pathophysiology. PMID- 27688084 TI - "Diabetic nephropathy" in a non-diabetic patient. AB - Kimmelstiel and Wilson originally described nodular glomerulosclerosis as the pathognomonic lesion of diabetic nephropathy. Nevertheless, nodular glomerulosclerosis pattern can rarely occur in non-diabetic patients. In such cases, the differential diagnosis includes membranoproliferative glomerulonephritis, light or heavy chain deposition disease, amyloidosis, fibrillary and immunotactoid glomerulonephritis and chronic hypoxic or ischemic conditions. In cases that the above entities cannot be proven, the term idiopathic nodular glomerulosclerosis is given. Here, we report a case of a male patient with renal failure stage IV and non-nephrotic range proteinuria. He had a history of heavy smoking and hypertension. The kidney biopsy revealed diabetic like lesions. However, there was no evidence of glucose impairment despite the thorough work-up at the biopsy time and thereafter. The laboratory data and the electron microscopy of the specimen could not prove any other cause of nodular glomerulosclerosis, and the final diagnosis was idiopathic nodular glomerulosclerosis. Moreover, we focus on the pathological differential diagnosis and work-up. PMID- 27688085 TI - Differentiation and prognostic markers in ampullary cancer: Role of p53, MDM2, CDX2, mucins and cytokeratins. AB - INTRODUCTION: Subclassification of ampullary adenocarcinomas into intestinal and pancreatobiliary type has prognostic and therapeutic implications. Immunohistochemical staining against specific biomarkers has been proven to be a useful adjunct in determining the exact histotype. Furthermore the immunohistochemical profile is suggestive of the molecular pathogenic mechanisms through which the tumor evolved. The aim of this study was to correlate p53, MDM2, CK7, CK20, MUC1, MUC2 and CDX2 expression in ampullary adenocarcinomas with the type of differentiation and patients' survival. MATERIAL AND METHODS: Forty seven radically resected ampullary adenocarcinomas were included in this study. Thirty-eight of them were eligible for survival analysis. Patients' data were retrospectively collected. All tumors were classified as intestinal or pancreatobiliary type, according to histologic criteria, and immunohistochemically stained against the aforementioned markers. RESULTS: There were 18 intestinal and 29 pancreatobiliary type ampullary adenocarcinomas. A trend was found between intestinal type tumors and large tumor size. CK20, MUC2 and CDX2 expression was more prevalent in intestinal type tumors, while MUC1 was more frequently expressed in pancreatobiliary type tumors. Neither p53 nor MDM2 differential expression between the two histotypes reached statistical significance. Multivariate analysis indicated CK20 and MUC1 as independent predictors of the histotype. Mean and median survival was 90.3 and 55 months respectively. Overall 5-year survival rate was 48%. Survival analysis indicated TNM stage as the only independent prognostic factor. Although significant difference in survival rates among the two histotypes was implied based on survival plots, this difference could not gain statistical significance. CONCLUSION: Immunoreactivity against CK20 and MUC1 in ampullary carcinomas is a useful adjunct to histologic examination in determining histotype. None of the immunohistochemical markers studied has prognostic significance. Future studies focused on other signaling pathways should seek further evidence of distinct tumorigenic mechanisms between histotypes of ampullary adenocarcinoma. PMID- 27688086 TI - Presence of high risk HPV DNA but indolent transcription of E6/E7 oncogenes in invasive ductal carcinoma of breast. AB - BACKGROUND AND AIMS: The causative role of high risk human papillomavirus (HR HPV) in breast cancer development is controversial, though a number of reports have identified HR-HPV DNA in breast cancer specimens. Nevertheless, most studies to date have focused primarily on viral DNA rather than the viral transcription. The aim of this study was to investigate the presence of HR-HPV in breast cancer tissues at HPV DNA level and HPV oncogenes mRNA level by in situ hybridization (ISH). METHODS: One hundred and forty six (146) cases of breast invasive ductal carcinoma(IDC) and 83 cases of benign breast lesions were included in the study. Type specific oligonucleotide probes were used for the DNA detection of HPV 16,18 and 58 by ISH. HR-HPV oncogenes mRNA was assayed by novel RNAscope HR-HPV HR7 assay ISH. p16 protein expression was evaluated by immunohistochemistry (IHC). RESULTS: HR-HPV 16,18 and 58 DNA were detected in 52 out of 146 (35.6%) IDC and in 3 out of 83 (3.6%) benign breast lesions by ISH. The HR-HPV mRNAs was detected only in a few specimens with strong HPV DNA positivity(4/25) in a few scattered cancer cells with very weak punctate nuclear and/or cytoplasmic staining. p16 over-expression did not correlate with the HPV DNA positive breast cancer samples(17/52 HPVDNA+ vs 28/94 HPV DNA-, p=0.731). CONCLUSIONS: HR-HPVs certainly exist in breast cancer tissue with less active transcription, which implies that the causal role of HPV in breast cancer development need further study. PMID- 27688087 TI - B-lymphoblastic leukemia in a patient with chronic lymphocytic leukemia: Sequential development of biclonal B-cell neoplasms over a 23-year period in a single individual. AB - Chronic lymphocytic leukemia (CLL) is an indolent mature B-cell neoplasm. During a prolonged disease course, a secondary B-cell neoplasm may arise in some patients, the most common example being the clonal evolution of CLL to diffuse large B-cell lymphoma, which is referred to as Richter transformation. Secondary de novo mature B-cell neoplasms arising in a patient with pre-existing CLL have been described; however, B-lymphoblastic leukemia (B-ALL) developing in untreated CLL is rare, and its clonal relationship to the primary neoplasm has been an interesting issue. Herein, we report an unusual case of the sequential development of CLL and B-ALL over a 23-year period in a 64-year-old male. Examination of the peripheral blood smear and bone marrow biopsy demonstrated dual neoplastic populations: small mature lymphocytes consistent with those seen in CLL and a population of blasts that were confirmed to be B-ALL by immunophenotyping. The biclonality of these two B-cell neoplasms was supported by cytogenetic studies. While an intrinsic immunodeficiency in patients with CLL may predispose them to the development of other malignancies, the pathogenesis of this unusual phenomenon remains to be further investigated. PMID- 27688088 TI - Diagnostic roles of MUC1 and GLUT1 in differentiating thymic carcinoma from type B3 thymoma. AB - MUC1 is a transmembrane mucin that has been related to tumor progression and outcome in various malignancies. GLUT1 is a member of the mammalian facilitative glucose transporter (GLUT) family of passive carriers that functions as an energy independent system for transporting glucose. Both of them are useful markers for the diagnosis, progression, and prognosis of various tumors, especially those that are cancerous. However, the clinical significance of MUC1 and GLUT1 in thymic epithelial tumors remains uncertain due to a lack of quality specimen and studies at sufficient scale, both owing, in part, to the rarity of the tumors. The aim of this article is to study the expression patterns of MUC1 and GLUT1 in thymic carcinoma and type B3 thymoma, and to evaluate their diagnostic value for these two types of tumors via immunohistochemistry. Forty-three patients were included in the study, including twenty-two with thymic carcinoma and twenty-one with type B3 thymoma. Tumor tissue sections were immunohistochemically stained for MUC1 and GLUT1; meanwhile, some tumors were also stained with CKpan, TDT, CD5, and CD117. MUC1 was expressed in a total of 17 cases, with a positive rate of 77.27% (17/22) in thymic carcinoma and 9.52% (2/21) in type B3 thymoma, revealing a significant difference (p<0.0001). A significant difference (p<0.0001) was also shown for GLUT1, where the positive rates for thymic carcinoma and type B3 thymoma were 100% (22/22) and 42.86% (9/21), respectively. The expression of MUC1 was significantly correlated with GLUT1 (p<0.0001). Furthermore, GLUT1 staining sensitivity and specificity for thymic carcinoma were 100% (22/22) and 70.97% (22/31), respectively, while MUC1 staining sensitivity and specificity were 77.27% (17/22) and 89.47% (17/19), respectively. In conclusion, our study shows that MUC1 and GLUT1 staining may play a useful role in differentiating thymic carcinoma from type B3 thymoma, with high sensitivity and specificity.

PMID- 27688090 TI - Metabolomic study of two rice lines infected by Rhizoctonia solani in negative ion mode by CE/TOF-MS. AB - Rhizoctonia solani is a fungal pathogen that causes sheath blight disease in rice plants. In this study, metabolomic analysis using CE/TOF-MS in negative ion mode was used to investigate the resistance response of resistant and susceptible rice lines (32R and 29S, respectively) due to R. solani infection. Two rice lines showed different responses to the infection of R. solani. In 32R, R. solani infection induced significant increases in adenosine diphosphate (ADP), glyceric acid, mucic acid and jasmonic acid. In 29S, inosine monophosphate (IMP) was involved in the plant response to R. solani infection. Phenol compounds showed an increase as a response of the rice lines to R. solani infection. The study suggests that R. solani infection effects in 32R are associated with the induction of plant metabolic processes such as respiration, photorespiration, pectin synthesis, and lignin accumulation. In 29S, the R. solani infection is suggested to correlate with nitrogen metabolism. PMID- 27688091 TI - Antioxidative response in variegated Pelargonium zonale leaves and generation of extracellular H2O2 in (peri)vascular tissue induced by sunlight and paraquat. AB - In this study we exposed variegated leaves of Pelargonium zonale to strong sunlight (>1100MUmolm-2s-1 of photosynthetically active radiation) with and without paraquat (Pq), with the aim to elucidate the mechanisms of H2O2 regulation in green and white tissues with respect to the photosynthetically dependent generation of reactive oxygen species (ROS). Sunlight induced marked accumulation of H2O2 in the apoplast of vascular and (peri)vascular tissues only in green sectors. This effect was enhanced by the addition of Pq. In the presence of diphenyl iodide, an NADPH oxidase inhibitor, H2O2 accumulation was abolished. Distinct light-induced responses were observed: in photosynthetic cells, sunlight rapidly provoked ascorbate (Asc) biosynthesis and an increase of glutathione reductase (GR) and catalase activities, while in non-photosynthetic cells, early up-regulation of soluble ascorbate peroxidase, dehydroascorbate reductase (DHAR) and GR activities was observed. Paraquat addition stimulated DHAR and GR activities in green sectors, while in white sectors activities of monodehydroascorbate reductase, DHAR and class III peroxidases, as well as Asc content rapidly increased. Differential antioxidative responses in the two tissues in the frame of their contrasting metabolisms, and the possible role of (peri)vascular H2O2 in signaling were discussed. PMID- 27688092 TI - The alkaline tolerance in Lotus japonicus is associated with mechanisms of iron acquisition and modification of the architectural pattern of the root. AB - The response of fifty-four Lotus japonicus ecotypes, and of six selected ecotypes was investigated under alkaline conditions. Sensitive, but not tolerant ecotypes, showed interveinal chlorosis under all alkalinity conditions and high mortality under extreme alkalinity. Interveinal chlorosis was associated with Fe deficiency, as a reduced Fe2+ shoot content was observed in all sensitive ecotypes. In addition, some showed a decline in photosynthesis rate and PSII performance compared to the control. In contrast, some tolerant ecotypes did not change these parameters between treatments. Alkaline tolerance could be explained by a mechanism of Fe acquisition and a root structural modification. This conclusion was based on the fact that all tolerant, but not the sensitive ecotypes, presented high ferric reductase oxidase activity under alkaline stress compared to the control, and a Herringbone root pattern modification. On this basis, the analysis of these mechanisms of alkaline tolerance could be used in screening programs for the selection of new tolerant genotypes in the Lotus genus.

AB - The recent Zika virus (ZIKV) epidemic has highlighted the poor knowledge on its physiopathology. Recent studies showed that ZIKV of the Asian lineage, responsible for this international outbreak, causes neuropathology in vitro and in vivo. However, two African lineages exist and the virus is currently found circulating in Africa. The original African strain was also suggested to be neurovirulent but its laboratory usage has been criticized due to its multiple passages. In this study, we compared the French Polynesian (Asian) ZIKV strain to an African strain isolated in Central African Republic and show a difference in infectivity and cellular response between both strains in human neural stem cells and astrocytes. Consistently, this African strain led to a higher infection rate and viral production, as well as stronger cell death and anti-viral response. Our results highlight the need to better characterize the physiopathology and predict neurological impairment associated with African ZIKV. PMID- 27688095 TI - Defective Connective Tissue Remodeling in Smad3 Mice Leads to Accelerated Aneurysmal Growth Through Disturbed Downstream TGF-beta Signaling. AB - Aneurysm-osteoarthritis syndrome characterized by unpredictable aortic aneurysm formation, is caused by SMAD3 mutations. SMAD3 is part of the SMAD2/3/4 transcription factor, essential for TGF-beta-activated transcription. Although TGF-beta-related gene mutations result in aneurysms, the underlying mechanism is unknown. Here, we examined aneurysm formation and progression in Smad3-/- animals. Smad3-/- animals developed aortic aneurysms rapidly, resulting in premature death. Aortic wall immunohistochemistry showed no increase in extracellular matrix and collagen accumulation, nor loss of vascular smooth muscle cells (VSMCs) but instead revealed medial elastin disruption and adventitial inflammation. Remarkably, matrix metalloproteases (MMPs) were not activated in VSMCs, but rather specifically in inflammatory areas. Although Smad3 /- aortas showed increased nuclear pSmad2 and pErk, indicating TGF-beta receptor activation, downstream TGF-beta-activated target genes were not upregulated. Increased pSmad2 and pErk staining in pre-aneurysmal Smad3-/- aortas implied that aortic damage and TGF-beta receptor-activated signaling precede aortic inflammation. Finally, impaired downstream TGF-beta activated transcription resulted in increased Smad3-/- VSMC proliferation. Smad3 deficiency leads to imbalanced activation of downstream genes, no activation of MMPs in VSMCs, and immune responses resulting in rapid aortic wall dilatation and rupture. Our findings uncover new possibilities for treatment of SMAD3 patients; instead of targeting TGF-beta signaling, immune suppression may be more beneficial. PMID- 27688096 TI - The miR-367-3p Increases Sorafenib Chemotherapy Efficacy to Suppress Hepatocellular Carcinoma Metastasis through Altering the Androgen Receptor Signals. AB - The androgen receptor (AR) was found to suppress hepatocellular carcinoma (HCC) metastasis at late stages. Due to this discovery, we searched for some AR enhancers to increase the efficacy of Sorafenib chemotherapy, and identified the microRNA (miR)-367-3p, whose expression is positively correlated with AR expression in advanced HCC, as an HCC metastasis suppressor. Combining miR-367-3p with Sorafenib showed better efficacy to suppress HCC cell invasion in vitro and in vivo. Mechanism dissection revealed that miR-367-3p could increase AR expression via directly targeting the 3'UTR of MDM2 to decrease MDM2 protein expression. The resultant increase of AR expression might then promote the expression of FKBP5 and PHLPP, thus dephosphorylating and inactivating AKT and ERK, to suppress the HCC cell invasion. Interestingly, the suppression of pAKT by miR-367-3p could subsequently attenuate the phosphorylation of AR and MDM2, giving rise to additional enhancement of AR protein expression, effectively forming a positive feedback loop. Together, these results suggest that miR-367-3p may function as an AR enhancer to increase Sorafenib chemotherapy efficacy via altering the MDM2/AR/FKBP5/PHLPP/(pAKT and pERK) signals to better suppress HCC metastasis. Successful development of this newly combined chemotherapy in the future may help us to better suppress the HCC metastasis at late stages. PMID- 27688098 TI - The development of a liquid biopsy for head and neck cancers. AB - Developing non-invasive diagnostic tools in the field of head and neck oncology has been a challenge. Analysis of circulating tumour derivatives in a patient's blood has been explored in other solid cancers. This includes analysis of circulating tumour DNA, intact circulating tumour cells (CTCs) and exosomes. These circulating tumour derivatives provide avenues of investigation which can be representative of a patient's primary tumour signature and can be assessed from a patient's blood sample. In advanced stage cancer patients, these tumour derivatives are found in higher amounts, attributed to higher cellular turnover (apoptosis, autophagy), lysed CTCs and sloughing from necrotic tumours. Head and neck squamous cell carcinoma (HNSCC) patients often present with advanced disease associated with a poor 5-year survival of <50%. Outside of sophisticated imaging and clinical examination, there is a lack of available biomarkers to measure disease burden, and/or response to therapy. Implementation of a liquid biopsy in HNSCC through serial blood samples has the potential to detect metastatic events earlier, thereby allowing better selection of appropriate treatment choices, predict prognosis in patients with potentially curable disease, monitor systemic therapies and residual disease post-treatment. PMID- 27688097 TI - nab-Paclitaxel, cisplatin, and 5-fluorouracil followed by concurrent cisplatin and radiation for head and neck squamous cell carcinoma. AB - OBJECTIVES: We previously reported the efficacy of nab-paclitaxel added to cisplatin, 5-FU, and cetuximab (APF-C) followed by concurrent high dose bolus cisplatin and radiation therapy (CRT) in patients with locally advanced head and neck squamous cell carcinoma (HNSCC). In this phase II trial, we determined the efficacy of APF (without cetuximab) followed by CRT in similar patients. MATERIALS AND METHODS: Eligible patients had stage III-IV oropharynx (OP), larynx, or hypopharynx SCC and adequate organ function and performance status. T1 tumors were excluded. Patients were treated with three cycles of APF followed by CRT. Efficacy endpoints included two-year disease-specific survival (DSS), progression-free survival (PFS), overall survival (OS), and relapse rate. RESULTS: Thirty patients were enrolled. Most patients were smokers (77%) with bulky T3/4 (73%) and N2/3 (83%) tumors. Analyses were stratified for human papilloma virus (HPV) status: HPV-related OPSCC (n=17; 57%) and HPV-unrelated HNSCC (n=13; 43%). With a minimum follow-up of 21months, relapse occurred in 1 (3%) patient. Two-year DSS was 94% in HPV-related OPSCC and 100% in HPV-unrelated HNSCC. Two-year PFS was 94% in HPV-related OPSCC and 100% in HPV-unrelated HNSCC. Two-year OS was 94% in HPV-related OPSCC and 92% in HPV-unrelated HNSCC. Causes of death were relapse (1), treatment-related mortality (1), and co-morbidity (1). Two patients with HPV-unrelated HNSCC treated with APF declined CRT and remained free of relapse at 36 and 28months of follow-up. CONCLUSION: This phase II trial demonstrated favorable two-year DSS, PFS, and OS and a low relapse rate in HPV unrelated HNSCC and HPV-related OPSCC treated with APF followed by CRT. PMID- 27688099 TI - Oral cancer: Deregulated molecular events and their use as biomarkers. AB - Oral Cancer (OC) is a subset of head and neck cancer (HNC) with an annual worldwide incidence of 275,000 cases. OC remains a significant burden worldwide in terms of diagnosis, treatment and prognosis. Despite desirable outcomes in early diagnosed OCs and treatment advances most OCs are detected in advanced stages. The 5-year survival rate of early-stage disease is ~80% and that of late stage disease is only ~20%. Recurrence and chemoresistance from a treatment point of view and pain and disfiguration are important factors contributing to the high morbidity and mortality of OC. Furthermore the process of oral carcinogenesis is complex and not yet fully understood. Consequently numerous potential biomarkers have been hypothesised though controversial results across the board hamper their clinical implementation. Of greatest advantage would be biomarkers signalling early events preceeding OC. Biomarker targets predominately involve deregulated molecular events that participate in cell signalling, growth, survival, motility, angiogenesis and cell cycle control but can also use changes in metabolic genes to discriminate healthy form disease state. Promising potential biomarkers include the growth signalling oncogenes, Epidermal Growth Factor Receptor and Cyclin D1, the anti-growth signalling components p53 and p21, apoptotic effectors such as Bcl-2 and also components involved in immortalisation, angiogenesis, invasion and metastasis processes. Translation of these potential biomakers to the patients is closer than ever though few issues remain to be resolved. Firstly large clinical trials are needed to validate their clinical applicability but also standardised methods of collection, storage and processing methods are needed to minimise variability. PMID- 27688100 TI - Patterns of failure after reirradiation with intensity-modulated radiation therapy and the competing risk of out-of-field recurrences. AB - PURPOSE: To describe patterns of failure (POF) after reirradiation (reRT) with intensity modulated radiation therapy (IMRT) for recurrent/second primary squamous cell carcinoma of the head and neck. METHODS: From 08/2004-02/2013, 75 consecutive patients received reRT with IMRT. Gross tumor was generally treated with a 5mm planning target volume (PTV) margin. For postoperative cases, a 5mm PTV was added to the clinical target volume which included the postoperative bed. Elective neck coverage was not standard. POF were characterized by correlating the recurrent tumor location on CT-imaging with the reRT IMRT plan. RESULTS: Patients received definitive reRT (55%) or postoperative reRT (45%) to a median 60Gy (range, 59.4-70Gy). Most patients (88%) received concurrent chemotherapy including induction (16%). The median overall survival was 1.8years. Isolated local-regional recurrence (LRR) was the most common failure-type (2-year cumulative incidence [CI] 22.5% [95% C.I. 13.6-32.7%]), but concurrent LRR and distant-failure occurred frequently (2-year CI LRR+distant-failure 19.6% [95% C.I. 11.3-29.5%]); isolated distant-failure was rare (2-year CI 5.7% [95% C.I. 1.8-12.8%]). The 2-year in-field control was 65% (95% C.I. 52-81%) reflecting encouraging control within the irradiated target. Patients with gross disease were more likely to recur in-field (p=0.02), whereas postoperative patients were more likely to recur out-of-field/marginally than in-field (p=0.02). CONCLUSIONS: POF after reRT differ when treating gross disease or postoperatively and should be considered when delineating reRT targets. Aggressive local therapy resulted in favorable in-field control, yet there remains a high competing risk of regional and distant micrometastatic disease. Better systemic agents are needed to control clinically occult local-regional and distant disease. PMID- 27688101 TI - The effect of human papillomavirus on DNA repair in head and neck squamous cell carcinoma. AB - Much of the current literature regarding the molecular pathophysiology of human papillomavirus (HPV) in head and neck squamous cell carcinoma (HNSCC) has focused on the virus's effect on cell cycle modulation and cell proliferation. A second mechanism of pathogenicity employed by HPV, dysregulation of cellular DNA repair processes, has been more sparsely studied. The purpose of this review is to describe current understanding about the effect of HPV on DNA repair in HNSCC, taking cues from cervical cancer literature. HPV affects DNA-damage response pathways by interacting with many proteins, including ATM, ATR, MRN, gamma-H2AX, Chk1, Chk2, p53, BRCA1, BRCA2, RAD51, Rb-related proteins 107 and 130, Tip60, and p16INK4A. Further elucidation of these pathways could lead to development of targeted therapies and improvement of current treatment protocols. PMID- 27688102 TI - PARTNER: An open-label, randomized, phase 2 study of docetaxel/cisplatin chemotherapy with or without panitumumab as first-line treatment for recurrent or metastatic squamous cell carcinoma of the head and neck. AB - OBJECTIVE: This phase 2 estimation study evaluated docetaxel/cisplatin with/without panitumumab, an anti-epidermal growth factor receptor monoclonal antibody, as first-line therapy for recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN). PATIENTS AND METHODS: Randomized patients received docetaxel/cisplatin (75mg/m(2) each) with/without panitumumab (9mg/kg) in 21-day cycles. Patients randomized to panitumumab+chemotherapy could continue panitumumab monotherapy after completing six chemotherapy cycles without progression; patients randomized to chemotherapy alone could receive second-line panitumumab after progression. Progression-free survival (PFS) was the primary endpoint. Secondary endpoints included overall survival (OS), overall response rate (ORR), time to response (TTR), duration of response (DOR), and safety. A protocol amendment limited enrollment to patients <70years owing to excess toxicity in older patients and added mandatory pegfilgrastim/filgrastim support. Outcomes were also analyzed by human papillomavirus status. RESULTS: 103 of the 113 enrolled patients were evaluable and randomized to receive ?1 dose of first line treatment. Median PFS for panitumumab+chemotherapy was 6.9 (95% CI=4.7-8.3) months versus 5.5 (95% CI=4.1-6.8) months for chemotherapy alone (hazard ratio [HR]=0.629; 95% CI=0.395-1.002; P=0.048). ORR for panitumumab+chemotherapy was 44% (95% CI=31-58%) versus 37% (95% CI=24-51%) for chemotherapy alone (odds ratio [OR]=1.37; 95% CI=0.57-3.33). Median OS for panitumumab+chemotherapy was 12.9 (95% CI=9.4-18.5) months versus 13.8 (95% CI=11.8-22.9) months for chemotherapy alone (HR=1.103; 95% CI=0.709-1.717). Median TTR for panitumumab+chemotherapy treatment was 6.9weeks versus 11.0weeks for chemotherapy alone. Median DOR was 8.0 (95% CI=5.7-11.1) months with panitumumab+chemotherapy versus 5.1 (95% CI=4.4 7.2) months with chemotherapy alone. Grade 3/4 adverse event incidence was 73% with panitumumab+chemotherapy versus 56% with chemotherapy alone. 41% and 55% of patients in the panitumumab+chemotherapy and chemotherapy-alone arms, respectively, received panitumumab monotherapy. CONCLUSION: The addition of panitumumab to docetaxel/cisplatin may improve PFS in recurrent/metastatic SCCHN and has the potential to improve outcomes in these fully, or mostly, active patients. PMID- 27688103 TI - Oncologic outcomes and patient-reported quality of life in patients with oropharyngeal squamous cell carcinoma treated with definitive transoral robotic surgery versus definitive chemoradiation. AB - OBJECTIVE: It has been postulated that treatment outcomes are similar between transoral robotic surgery (TORS) and definitive chemoradiation (CRT) for oropharyngeal squamous cell carcinomas (OPSCC). We compared oncologic and quality of life (QOL) outcomes between definitive CRT and definitive TORS. MATERIALS AND METHODS: An observational comparison study was performed on 92 patients treated with TORS+/-adjuvant therapy and 46 patients treated with definitive CRT between July 2005 and January 2016. The Kaplan Meier method was used for survival analyses, and the Mann-Whitney test was used to compare QOL scores between groups. RESULTS: All patients had T0-T2 and N0-N2 disease, although CRT patients had higher clinical staging (p<0.001). HPV+ disease was present in 79% (n=73) of TORS patients and 91% (n=19) of tested CRT patients. Median follow-up was 22.1months (range: 0.33-83.4). There were no significant differences in locoregional control or overall survival between CRT and TORS groups. Definitive TORS resulted in better saliva-related QOL than definitive CRT at 1, 6, 12, and 24months (p<0.001, p=0.025, p=0.017, p=0.011). Among TORS patients, adjuvant therapy was associated with worse QOL in the saliva domain at 6, 12, and 24months (p<0.001, p<0.001, p=0.007), and taste domain at 6 and 12months (p=0.067, p=0.008). CONCLUSION: Definitive CRT and definitive TORS offer similar rates of locoregional control, overall survival, and disease-free survival in patients with early stage OPSCC. TORS resulted in significantly better short and long-term saliva-related QOL, whereas adjuvant therapy was associated with worse saliva and taste-related QOL compared to TORS alone. PMID- 27688104 TI - Diabetes mellitus, metformin and head and neck cancer. AB - INTRODUCTION: Diabetes mellitus (DM (Diabetes Mellitus)) is directly associated with some cancers. However, studies on the association between diabetes mellitus and head and neck cancer (HNC (Head and Neck Cancer)) have rendered controversial results. The objective of this study was to evaluate the association between DM and HNC, as well as the impact of metformin use on the risk of HNC. MATERIAL AND METHODS: This case-control study was conducted within the framework of the Brazilian Head and Neck Genome Project in 2011-2014. The study included 1021 HNC cases with histologically confirmed squamous cell carcinoma of the head and neck admitted to five large hospitals in Sao Paulo state. A total of 1063 controls were selected in the same hospitals. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using unconditional logistic regression. RESULTS: Diabetic participants had a decreased risk of HNC (OR=0.68; 95% CI: 0.49-0.95) than non-diabetic participants, and this risk was further decreased among diabetic metformin users (OR=0.54; 95% CI: 0.29-0.99). Diabetic metformin users that were current smokers (OR=0.13; 95% CI: 0.04-0.44) or had an alcohol consumption of >40g/day (OR=0.31; 95% CI: 0.11-0.88) had lower risk of HNC than equivalent non-diabetic participants. CONCLUSION: The risk of HNC was decreased among diabetic participants; metformin use may at least partially explain this inverse association. PMID- 27688105 TI - Low etiologic fraction for human papillomavirus in larynx squamous cell carcinoma. AB - BACKGROUND: Human Papillomavirus (HPV) is a cause of oropharyngeal squamous cell carcinoma (OPSCC), but its pathogenic role in larynx squamous cell carcinoma (LSCC) remains unclear. MATERIAL AND METHODS: A single-institutional, retrospective case-series was performed to estimate the etiological fraction (EF) for HPV in LSCC. Eligible cases included 436 consecutive cases of LSCC diagnosed (2005-2014) at The Ohio State University Medical Center. HPV DNA presence was detected by consensus primer PCR (Inno-LiPa) and HPV type-specific qPCR. HPV E6/E7 mRNA expression was detected by type-specific qRT-PCR. Tumor p16 expression was evaluated by immunohistochemistry (IHC). RESULTS: HPV DNA was detected by Inno-LiPa in 54 of 404 (13.4%, 95% CI 10.2-17.1) evaluable samples but was confirmed by HPV type-specific qPCR in only 14 (3.5%, 95% CI 1.9-5.7). Only 7 of 404 (1.7%, 95% CI 0.7-3.5) LSCC were positive for HPV E6/E7 mRNA expression, including HPV16 (n=4) and 1 each for 11, 26 and 33. In the HPV11-positive tumor, Sanger sequencing discovered 6 nucleotide mutations in the upstream regulation region, E6 and E7. Of 404 LSCC, 18 had strong and diffuse p16 expression. In comparison to a gold standard of HPV E6/E7 mRNA expression, p16 expression had a sensitivity of 71.4% (95% CI 29.0-96.3), specificity of 96.7% (95% CI 94.5-98.3), positive-predictive-value (PPV) of 27.8% (95% CI 9.7-53.5) and negative predictive-value of 99.5% (95% CI 98.1-99.9). CONCLUSION: The EF for HPV in LSCC is low (1.7%) in a geographic region with high EF for OPSCC. Low-risk HPV may rarely cause LSCC. Finally, p16 expression has poor PPV for HPV in LSCC. PMID- 27688107 TI - Trends of oral cavity, oropharyngeal and laryngeal cancer incidence in Scotland (1975-2012) - A socioeconomic perspective. AB - AIM: To examine current incidence trends (1975-2012) of oral cavity (OCC), oropharyngeal (OPC) and laryngeal cancer in Scotland by socioeconomic status (SES). METHODS: We included all diagnosed cases of OCC (C00.3-C00.9, C02-C06 excluding C2.4), OPC (C01, C2.4, C09-C10, C14) and laryngeal cancer (C32) on the Scottish Cancer Registry (1975-2012) and annual midterm population estimates by age, sex, geographic region and SES indices (Carstairs 1991 and Scottish Index of Multiple Deprivation 2009). Age-standardized incidence rates were computed and adjusted Poisson regression rate-ratios (RR) compared subsites by age, sex, region, SES and year of diagnosis. RESULTS: We found 28,217 individuals (19,755 males and 8462 females) diagnosed with head and neck cancer (HNC) over the study period. Between 1975 and 2012, relative to the least deprived areas, those living in the most deprived areas exhibited the highest RR (>double) of OCC, OPC and laryngeal cancer, and an almost dose-like response was observed between SES and HNC incidence. Between 2001 and 2012, this socioeconomic inequality tended to increase over time for OPC and laryngeal cancer but remained relatively unchanged for OCC. Incidence rates increased markedly for OPC, decreased for laryngeal cancer and remained stable for OCC, particularly in the last decade. Males exhibited significantly higher RRs compared to females, and the peak age of incidence of OPC was slightly lower than the other subsites. CONCLUSION: Contrary to reports that OPC exhibits an inverse socioeconomic profile, Scotland country level data show that those from the most deprived areas consistently have the highest rates of head and neck cancers. PMID- 27688106 TI - Quantitative body mass characterization before and after head and neck cancer radiotherapy: A challenge of height-weight formulae using computed tomography measurement. AB - OBJECTIVES: We undertook a challenge to determine if one or more height-weight formula(e) can be clinically used as a surrogate for direct CT-based imaging assessment of body composition before and after radiotherapy for head and neck cancer (HNC) patients, who are at risk for cancer- and therapy-associated cachexia/sarcopenia. MATERIALS AND METHODS: This retrospective single-institution study included 215 HNC patients, treated with curative radiotherapy between 2003 and 2013. Height/weight measures were tabulated. Skeletal muscle mass was contoured on pre- and post-treatment CT at the L3 vertebral level. Three common lean body mass (LBM) formulae (Hume, Boer, and James) were calculated, and compared to CT assessment at each time point. RESULTS: 156 patients (73%) had tumors arising in the oropharynx and 130 (61%) received concurrent chemotherapy. Mean pretreatment body mass index (BMI) was 28.5+/-4.9kg/m(2) in men and 27.8+/ 8kg/m(2) in women. Mean post-treatment BMI were 26.2+/-4.4kg/m(2) in men, 26+/ 7.5kg/m(2) in women. Mean CT-derived LBM decreased from 55.2+/-11.8kg pre-therapy to 49.27+/-9.84kg post-radiation. Methods comparison revealed 95% limit of agreement of +/-12.5-13.2kg between CT and height-weight formulae. Post-treatment LBM with the three formulae was significantly different from CT (p<0.0001). In all instances, no height-weight formula was practically equivalent to CT within+/ 5kg. CONCLUSION: Formulae cannot accurately substitute for direct quantitative imaging LBM measurements. We therefore recommend CT-based LBM assessment as a routine practice of head and neck cancer patient body composition. PMID- 27688108 TI - A cohort study into head and neck cancer mortality in Belgium (2001-11): Are individual socioeconomic differences conditional on area deprivation? AB - OBJECTIVE: The aim of this study is to assess to what extent individual and area level socioeconomic position (SEP) are associated to head and neck cancer (HNC) mortality and to what extent they contribute to regional variation in HNC mortality in Belgium. MATERIALS AND METHODS: Data on men aged 40-64 are collected from a population based dataset based on the 2001 Belgian census linked to register data on emigration and mortality for 2001-2011. Individual SEP is measured using education, employment status and housing conditions. Deprivation at municipal level is measured by a deprivation index. Absolute mortality differences are estimated by age standardised mortality rates. Multilevel Poisson models are used to estimate the association and interaction between HNC mortality and individual and area-level SEP, and to estimate the regional variation in HNC mortality. RESULTS: HNC mortality rates are significantly higher for men with a low SEP and men living in deprived areas. Cross-level interactions indicate that the association between individual SEP and HNC mortality is conditional on area deprivation. HNC mortality in deprived areas is especially high among high-SEP men. As a result, social disparities appear to be smaller in more deprived areas. Regional variation in HNC mortality was significant. Population composition partially explains this regional variation, while area deprivation and cross level interactions explains little. CONCLUSION: Both individual and area-level deprivation are important determinants of HNC mortality. Underlying trends in incidence and survival, and risk factors, such as alcohol and tobacco use, should be explored further. PMID- 27688109 TI - Geographic variation in Medicare treatment costs and outcomes for advanced head and neck cancer. AB - BACKGROUND: Advanced head and neck cancer (HNC) is a complex group of diseases that requires the input and coordination of multiple providers. While there are general guidelines for treatment, there is also considerable variation in how patients are treated, and how long they survive after treatment. It is unclear how the treatment variations relate to treatment costs and survival. METHODS: We identified 3678 Medicare patients with advanced HNC treated in 12 US regions between 2004 and 2009 using the linked database containing Medicare and Surveillance Epidemiology and End Results (SEER) data. We calculated average cost per patient during the period three months before to 12months after diagnosis for each region. Costs included inpatient hospital, outpatient, physician, and durable medical equipment charges. We also calculated three-year overall survival for each of the regions. RESULTS: The mean cost-per-patient varied substantially among the regions, ranging from $51,857 for Utah to $82,181 for Detroit. Utah incurred the lowest total costs within one year of advanced HNC diagnosis ($51,857 per patient, 95% CI $42,285-$61,429), whereas Detroit had the highest costs ($82,181 per patient, 95% CI $74,752-$89,610). Overall survival also varied among the regions, ranging from 45months in Kentucky to 58months in Washington. There was little correlation between expenditures and length of survival, with correlation coefficient of 0.0088. CONCLUSION: Despite significant variation in both expenditures and survival among the regions, we found no correlation between costs and mean survival time, suggesting that more costly care did not lead to improved outcomes. PMID- 27688110 TI - A clinicopathologic study of head and neck rhabdomyosarcomas showing FOXO1 fusion positive alveolar and MYOD1-mutant sclerosing are associated with unfavorable outcome. AB - BACKGROUND: Based on their distinctive histologic and genetic features, the latest WHO classification of soft tissue tumors includes four pathologic variants of rhabdomyosarcoma (RMS): embryonal (ERMS), alveolar (ARMS), spindle cell sclerosing (SRMS-ScRMS) and pleomorphic RMS. The aim of this study focused on a detailed clinicopathologic and survival analysis of head and neck RMS (HNRMS) using the latest pathologic and molecular criteria reflecting this new subclassification in a large cohort. PATIENTS AND METHODS: Patients managed for HNRMS in our institution (1996-2015) were analyzed. The presence of a FOXO1 fusion was required for the classification of ARMS. MYOD1 mutations in SRMS-ScRMS were tested when material available. Univariate and multivariate analyses were performed to evaluate variables related to overall survival (OS). RESULTS: Ninety nine HNRMS patients (52 males and 47 females, mean of 16years) were included in the study after pathologic re-review. The most common location was parameningeal (PM) (n=64), followed by non-orbital/non-PM (n=25) and orbital (n=10). There were 53 ERMS, 33 fusion-positive ARMS and 13 SRMS-ScRMS [SRMS (8); ScRMS (5)]. The 5 year OS rate for ERMS patients was significantly higher (82%) compared to ARMS (53%) and SRMS-ScRMS (50%) [SRMS (75%); ScRMS (30%)]. Univariate analysis showed that survival was dependent on histology (P=0.012), tumor size >5cm (P<0.001), regional lymph node involvement (P=0.002), metastasis at initial presentation (P<0.001), stage (P<0.001), and recurrence (P=0.002). Multivariate analysis confirmed histologic subtype to be significant (P=0.043). CONCLUSION: Our findings reinforce that HNRMS is a heterogenous disease with ARMS and SRMS-ScRMS having an equally unfavorable outcome. PMID- 27688112 TI - Induction chemotherapy for squamous cell carcinomas of the oral cavity: A cumulative meta-analysis. AB - Induction chemotherapy (ICT) is a controversial treatment for head and neck squamous cell carcinomas (HNSCC). Despite numerous randomized controlled trials (RCTs), a majority do not have enough statistical power alone to conclude ICT's treatment value among oral squamous carcinoma patients (OSCC) since many addressed HNSCC as one entity instead of by specific subtypes. By performing a systematic review and cumulative meta-analysis, we aim to determine the benefits of ICT in OSCC therapy. A literature search identified for RCTs comparing OSCC patients who received ICT against those without. Log-hazard ratio, and relative risk were used for comparison. Heterogeneity was determined using the I(2) statistic package. The primary endpoint was overall survival (OS), followed by disease-free survival (DFS), locoregional recurrence (LRR) and distant metastasis (DM) as secondary endpoints. RESULTS: 27 randomized trials were included for analysis (n=2872 patients). The shortest median follow-up was 15months whereas the longest was 11.5years. ICT does not improve OS (HR=0.947, 95% CI 0.85-1.05, p=0.318), DFS (RR=1.05, 95% CI 0.92-1.21, p=0.462) and DM (RR=0.626, CI 95% 0.361 1.086, p=0.096) compared to locoregional treatment alone. However, there was a significant improvement to LRR (RR=0.778, 95% CI 0.622-0.972, p=0.027). There is no evidence ICT improves survival outcomes for OSCC patients. However, ICT reduces locoregional recurrence of OSCC, which may need further verification. PMID- 27688113 TI - Pretreatment pain predicts perineural invasion in oral squamous cell carcinoma: A prospective study. AB - OBJECTIVES: Perineural invasion (PNI) is an established poor prognostic pathological feature for oral squamous cell carcinoma (OSCC). The purpose of this study was to analyze the role of pretreatment parameters in predicting PNI for OSCC. MATERIALS AND METHODS: We prospectively enrolled into our study 102 newly diagnosed OSCC patients, who were surgically treated from 2011 to 2012. Before treatment, patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire H&N35 and the visual analogue scale (VAS) for cancer pain. Pathological examination was performed to ascertain PNI status in all patients. Patients were divided into two groups, those with PNI and without PNI. Pretreatment parameters were compared between the two groups. RESULTS: In univariate analysis, clinical T classification (P<0.001), painkiller use (P=0.001), problem with social eating (P<0.001) and social contact (P=0.002), VAS scores of primary pain (P<0.001) and referred pain (P=0.004) were found to be associated with PNI. Multivariate logistic regression analysis further revealed VAS score of primary pain (P=0.001, OR 2.014) and T3-4 classification (P=0.014, OR 6.422) were independent predictors of PNI. A regression equation incorporating pretreatment pain was developed to predict the probability of having PNI. CONCLUSION: PNI can be predicted by higher pretreatment VAS score of primary pain, as well as more advanced clinical T classification. Careful evaluation of pretreatment pain of primary tumor can thus be helpful in improving treatment decision making for OSCC. PMID- 27688111 TI - Prognostic significance of non-HPV16 genotypes in oropharyngeal squamous cell carcinoma. AB - OBJECTIVES: Recent studies have found that cases with oropharyngeal squamous cell carcinoma (OPSCC) positive for HPV16 genotype have better overall survival compared with cases positive for other HPV genotypes. We sought to further replicate these studies and determine if this relationship is modified by expression of p16 tumor suppressor protein. MATERIAL AND METHODS: We identified 238 OPSCC cases from the Carolina Head and Neck Cancer Study (CHANCE) study, a population based case-control study. Tumors that tested positive solely for HPV16 genotype and no other genotypes with PCR were classified as HPV16-positive. Tumors positive for any other high-risk HPV genotype were classified as non-HPV16 positive. Expression of p16 in the tumor was determined with immunohistochemistry. Follow-up time was calculated from the date of diagnosis to date of death or December 31, 2013. Overall survival was compared with the Kaplan Meier curves and log-rank test. Hazard ratios (HR) adjusted for smoking, alcohol use, sex, race, and age was calculated with the Cox proportional hazard regression. RESULTS: Cases with HPV16-positive OPSCC had better overall survival than cases with non-HPV16-positive OPSCC (log-rank p-value: 0.010). When restricted to OPSCC cases positive for p16 expression, the same trend continued (log-rank p-value: 0.002). In the adjusted model, cases with non-HPV16-positive OPSCC had greater risk of death compared to cases with HPV16-positive tumors (HR: 1.92; 95% CI: 1.03, 3.60). CONCLUSIONS: This finding indicates that HPV genotyping carries valuable prognostic significance in addition to p16 status and future survival studies of OPSCC should take into account differing HPV genotypes. PMID- 27688114 TI - Autophagy: A boon or bane in oral cancer. AB - Autophagy is a catabolic process involving cellular recycling and is believed to play a distinct role in cell survival especially when exposed to stressors, rendering it comparable to the elixir sustaining life. It plays a significant role in various conditions like cancers, neuropathies, heart diseases, auto immune diseases, etc. Its role in tumorigenesis and cancer therapeutics is worth exploring. Autophagy is believed to help in survival and longevity of cancer cells by buffering metabolic stress. Inhibition of autophagy in an environment of nutrient deprivation leads to cell death. Autophagy is also seen to facilitate metastasizing tumor cells in surviving the conditions of metabolic deprivation and in recovery when conditions turn favorable. Many current cancer therapies tend to inflict metabolic stress, thus autophagy inhibitors may be useful in cancer treatment. As per the adage, "excess of anything is bad", the autophagy promoters can also be exploited as beneficial tools in the fight against cancer. Another method for tumor-cell elimination can be by inducing autophagic cell death through over-stimulation. Oral cancers are becoming a leading cause of deaths worldwide. Much remains to be explored about the role autophagy plays in progression of head and neck cancers, so as to harness it in the therapeutics of these cancers. Research on autophagy is still in its infancy. There are knowledge gaps in understanding this complex process. But there is no doubt that understanding exact mechanism behind autophagy will open up new avenues in cancer therapeutics and even prevention. PMID- 27688115 TI - Does elimination of planned postoperative radiation to the primary bed in p16 positive, transorally-resected oropharyngeal carcinoma associate with poorer outcomes? AB - OBJECTIVE: The purpose of our study is to compare oncologic and functional outcomes of p16-positive oropharyngeal squamous cell carcinoma (OPSCC) patients, in the presence and absence of planned radiation to the primary bed following transoral surgery (TOS), stratified by T-classification. METHODS: Retrospective cohort study of 261, T1-T4, consecutively TOS-treated OPSCC patients. RESULTS: At a median follow-up of 61months, local recurrence (LR) occurred in 6 (2.3%)patients (3 each in T1-T2 and T3-T4 groups), of which 5 had tumors in the tongue base and one in the tonsil. Of patients not receiving planned primary bed radiation, LR occurred in 3% of T1-T2s versus 17% of T3-T4s. In patients with T1 T2 tumors, Absolute Risk Reduction of LR with primary bed radiation was 3.26% (95% CI: -0.37%, 7%); Number Needed to Treat to prevent one LR was 31 (95% CI: 14.5, 271). Absolute Risk Increase for gastrostomy-tube with primary bed radiation was 34.4% (95% CI: 24%, 45%); Number Needed to Harm was 3 (95% CI: 2.2, 4.2), i.e., for every three patients with T1-T2 tumors receiving primary bed radiation, one had a gastrostomy-tube. CONCLUSIONS: Elimination of primary bed radiation in margin-negative resected, T1-T2 p16-positive OPSCC was not associated with significant compromise of local control, and correlated with superior swallowing preservation, assessed using gastrostomy rate as a surrogate. Lack of primary bed radiation in T3-T4 tumors associated with significantly increased LR rates. PMID- 27688116 TI - Prospective swallowing outcomes after IMRT for oropharyngeal cancer: Dosimetric correlations in a population-based cohort. AB - OBJECTIVES: To identify dose constraints to preserve swallowing after head and neck (H&N) radiotherapy using prospectively collected functional outcomes. MATERIALS AND METHODS: Stage III-IV oropharyngeal cancer patients were prospectively evaluated using the Royal Brisbane Hospital Outcome Measure for Swallowing and Performance Status Scale for H&N Cancer Patients at pre-treatment and 3, 6, 12, and 24months after intensity-modulated radiotherapy. Dosimetric parameters were correlated with swallowing function. RESULTS: Ninety-six patients were evaluated with median follow-up of 14.1months (interquartile range 9.9 26.3). Six patients (8.3%) remained feeding tube (FT) dependent at 12months. At 2years, 32.6% tolerated a normal diet without restrictions. Mean doses of 55Gy to supraglottic larynx, 44Gy to glottic larynx, 48Gy to cricopharyngeus, and 44Gy to esophageal inlet were associated with >25% risk of FT dependence at 6months. CONCLUSION: Higher mean doses to the larynx and pharyngo-esophageal junction were associated with longer duration of FT dependence and dietary restrictions. PMID- 27688117 TI - Comparison of spinal accessory dysfunction following neck dissection with harmonic scalpel and electrocautery - A randomized study. AB - INTRODUCTION: Harmonic scalpel is being increasingly used in neck dissection as alternative to conventional electro-cautery for achieving haemostasis. Use of harmonic scalpel has been shown to significantly reduce intra operative blood loss and intra operative time in neck dissection. But how safe is it with regards to nerve injury (spinal accessory nerve and other nerves) during neck dissection. We intended to study the spinal accessory nerve injury during neck dissection by both harmonic scalpel and electro cautery technique and compared postoperative recovery of shoulder function after neck dissection. METHODS: 40 patients undergoing selective neck dissection for primary oral malignancy were enrolled in this study. The Harmonic scalpel (HS) group consisted of 20 patients, and the electo cautery technique (ET) group had 20 patients. The following variables were examined: shoulder pain by visual analog scoring and shoulder function by means of degree of abduction and graded was grade I-0-90 degrees ; grade II-90-135 degrees ; grade III-135-180 degrees . They assessment was done at the time of discharge, 1month and 3month and six month after surgery. RESULTS: Though shoulder pain was almost similar at 1st week and 1month, however at 2nd and 6th month shoulder pain was found to be significantly lesser in harmonic scalpel group as compared to electro cautery. At 1week more no of patients had restricted shoulder mobility in HS as compared to EC group. But at 6months the shoulder function was found to be significantly better in HS group as compared to EC group (p value<0.05). CONCLUSION: Spinal accessory nerve function recovery after selective neck dissection is better in HS group as compared to the electro cautery group.

AB - CD59 is a complement regulatory protein that inhibits the formation of membrane attack complex of complement. In this study, we examined the expression and activity of tongue sole (Cynoglossus semilaevis) CD59 (CsCD59). CsCD59 possesses the conserved structural features of CD59 and shares 33%-46% sequence identities with other fish CD59. Expression of CsCD59 was high in liver, spleen, and muscle, and was stimulated by infection of bacterial pathogens. Recombinant CsCD59 (rCsCD59) exhibited an apparent inhibition effect on the activation of tongue sole serum complement. ELISA and microscopy detected binding of rCsCD59 to a number of Gram-negative and Gram-positive bacteria. Interaction with rCsCD59 did not affect bacterial viability but significantly enhanced bacterial resistance against the killing effect of fish serum. Together these results indicate that fish CD59 may to some degrees facilitate a general escape of bacteria from complement-mediated immunity. PMID- 27688118 TI - Single nucleotide polymorphisms as markers of genetic susceptibility for oral potentially malignant disorders risk: Review of evidence to date. AB - BACKGROUND: Oral cancers are preceded by oral potentially malignant disorders (OPMD). Understanding genetic susceptibility for OPMD risk could provide an opportunity for risk assessment of oral cancer through early disease course. We conducted a review of single nucleotide polymorphism (SNP) studies for OPMD risk. METHODS: We identified all relevant studies examining associations of SNPs with OPMD (leukoplakia, erythroplakia and oral sub-mucous fibrosis) conducted world wide between January, 2000 and February, 2016 using a combined keyword search on PubMed. Of these, 47 studies that presented results as odds ratios and 95% CI were considered for full review. RESULTS: The majority of eligible studies that explored candidate gene associations for OPMD were small (N<200 cases), limiting their scope to provide strong inference for any SNP identified to date in any population. Commonly studied SNPs were genes of carcinogen metabolism (n=18 studies), DNA repair (n=11 studies), cell cycle control (n=8 studies), extra cellular matrix alteration (n=8 studies) and immune-inflammatory (n=6 studies) pathways. Based on significant associations as reported by two or more studies, suggestive markers included SNPs in GSTM1 (null), CCND1 (G870A), MMP3 (-1171; promotor region), TNFalpha (-308; rs800629), XPD (codon 751) and Gemin3 (rs197412) as well as in p53 (codon 72) in Indian populations. However, an equal or greater number of studies reported null or mixed associations for SNPs in GSTM1 (null), p53 (codon 72), XPD (codon 751), XRCC (rs25487 C/T), GSTT1 (null) and CYP1A1m1 (MspI site). CONCLUSION: Candidate gene association studies have not yielded consistent data on risk loci for OPMD. High-throughput genotyping approaches for OPMD, with concurrent efforts for oral cancer, could prove useful in identifying robust risk-loci to help understand early disease course susceptibility for oral cancer. PMID- 27688120 TI - Characterisation of a new, highly effective method for detecting nematode eggs (Ascaris spp., Toxocara spp., Trichuris spp.) in sewage sludge containing flocculants. AB - Because traditional methods used for sewage sludge parasitological examinations have low sensitivity, a new, highly effective method (own method - OM) was devised. The principle of this method is to eliminate the flocculent effect on the structure of sewage sludge by mechanically damaging floccules in the presence of surfactants and to increase the effectiveness of egg isolation processes in large volumes of liquids. The objective of this study was to estimate the effectiveness of the OM in detecting nematode eggs in sewage sludge samples containing flocculants. In the first stage, the effectiveness of the OM was compared to 4 other methods routinely used in parasitological examinations of dehydrated sewage sludge. Next, method standardisation was performed using sewage sludge samples supplemented with eggs from 3 parasite species (Ascaris suum, Toxocara canis and Trichuris vulpis). The study demonstrated that OM efficiency was 6-65 times greater than other methods, depending on the method and type of detected eggs. Limit of detection (LOD) calculations for the OM were performed on samples supplemented with a known number of parasite eggs resulting in 10, 5 and 3 eggs/50 g of sample for A. suum, T. vulpis and T. canis eggs, respectively. The limits of quantification (LOQ) of the OM were established as 200 eggs/50 g of sample for A. suum and T. vulpis eggs and 50 eggs/50 g of sample for T. canis eggs. The rectilinear regression functions, which determined the relationship between the number of eggs detected in OM measurements and the number of eggs contained in the samples, were characterised by high and statistically significant coefficients of determination (r2). The slopes of the trend lines were 0.3188, 0.3821 and 0.3276, and the intercepts were -11.223, -9.0261 and 23.15 for A. suum, T. canis and T. vulpis eggs, respectively. Method sensitivity, calculated as the slope coefficient of the regression function and expressed as a percentage, ranged from 32% to 38% depending on egg type. The study confirmed that the OM may be applied to quantify parasite eggs in dehydrated sewage sludge containing polyelectrolytes. PMID- 27688121 TI - Brain mechanism of itch in atopic dermatitis and its possible alteration through non-invasive treatments. AB - Atopic dermatitis (AD) is a common chronic skin disease that is characterized by intense pruritus and has high impairment of quality of life. AD is often described as "the itch that rashes, rather than the rash that itches". Several studies suggest that mechanisms of central modulation play an important role in the development and maintenance of chronic itch. Therefore, treating the neurosensory aspects of itch is an important part in the management of chronic itch. However, little attention has been paid to the role of the central nervous system in the processing of itch in AD. Targeting itch-related anatomical structures in the brain with non-invasive treatments such as psychological interventions and transcranial Direct Current Stimulation (tDCS) could have an antipruritic effect in AD. Therefore, in this review article, we discuss the current progress in brain imaging research of itch, as well as the efficacy of non-invasive interventions for itch relief in this patient group. PMID- 27688122 TI - Cardio-respiratory responses to hypoxia combined with CO2 inhalation during maximal exercise. AB - We measured the effects of adding CO2 to an inhaled hypoxic gas mixture on cardio respiratory parameters during maximal exercise. Eight young males performed four incremental maximal exercise tests on cycle under ambient air, hypoxia (FIO2 0.125), inhaled CO2 (FICO2 0.045), and combination of hypoxia and inhaled CO2. The highest ventilation (VE) and VE/CO2 output were recorded in CO2 inhalation and combined treatments. Arterial O2 partial pressure was higher in combined than in hypoxia treatment, but the difference between the treatments narrowed from rest to end-exercise, at least partly because the magnitude of the increase in VE (%) at exercise was smaller in combined treatment than in hypoxia. Arterial O2 content was higher in combined treatment than in hypoxia at rest, but no more at maximal exercise. Cardiac output was higher and O2 extraction lower when breathing O2-poor gas mixtures than under the two other treatments. For a given oxygen consumption, hypoxia and combined treatment showed similar cardiac output and O2 extraction. PMID- 27688123 TI - A family nursing educational intervention supports nurses and families in an adult intensive care unit. AB - The family experience of critical illness is filled with distress that may have a lasting impact on family coping and family health. A nurse can become a source of comfort that helps the family endure. Yet, nurses often report a lack of confidence in communicating with families and families report troubling relationships with nurses. In spite of strong evidence supporting nursing practice focused on the family, family nursing interventions often not implemented in the critical care setting. This pilot study examined the influence of an educational intervention on nurses' attitudes towards and confidence in providing family care, as well as families' perceptions of support from nurses in an adult critical care setting. An academic-clinical practice partnership used digital storytelling as an educational strategy. A Knowledge to Action Process Framework guided this study. Results of pre-intervention data collection from families and nurses were used to inform the educational intervention. A convenience sample of family members completed the Iceland Family Perceived Support Questionnaire (ICE-FPSQ) to measure perception of support provided by nurses. Video, voice, and narrative stories of nurses describing their experiences caring for family members during a critical illness and family members' experiences with a critically ill family member also guided education plans. When comparing the pre and post results of the Family Nurse Practice Scale (FNPS), nurses reported increased confidence, knowledge, and skill following the educational intervention. Qualitative data from nurses reported satisfaction with the educational intervention. Findings suggest that engaging nurses in educational opportunities focused on families while using storytelling methods encourages empathic understandings. Academic-clinician teams that drive directions show promise in supporting families and nurses in critical care settings. Plans are moving forward to use this study design and methods in other critical care settings. PMID- 27688124 TI - Association between abnormal default mode network activity and suicidality in depressed adolescents. AB - BACKGROUND: Suicide is the second leading cause of death among 15- to 29-year olds in China, and 60 % of suicidal patients have a history of depression. Previous brain imaging studies have shown that depression and suicide may be associated with abnormal activity in default mode network (DMN) regions. However, no study has specifically investigated the relationship between DMN functional activity and suicidal behavior in depressed individuals. Therefore, in the present study, we directly investigated features of DMN brain activity in adolescent patients with histories of depression and attempted suicide. METHODS: A total of 35 sex- and age-matched suicidal depressed patients were compared with 18 non-suicidal depressed patients and 47 healthy controls. We explored functional activity changes in DMN regions that could be associated with suicidal behavior by comparing resting-state functional magnetic resonance imaging (rs fMRI) signals using independent component analysis (ICA). Scores on six clinical scales that measure depression severity (Hamilton Depression Scale (HDRS) and Beck Depression Inventory (BDI)) and suicidal traits (Barratt Impulsiveness Scale (BIS-11), Suicide Attitude Questionnaire (SAQ), Beck Hopelessness Scale (BHS), and Scale for Suicide Ideation (SSI)) were compared in the three groups. RESULTS: Compared with the healthy controls, all of the evaluated depressed patients showed increased functional connectivity in select DMN regions. The suicidal patients showed increased connectivity in the left cerebellum and decreased connectivity in the right posterior cingulate cortex (PCC), whereas the non suicidal depressed patients showed increased connectivity in the left superior frontal gyrus, left lingual gyrus and right precuneus and decreased connectivity in the left cerebellum. Compared to the non-suicidal patients, the suicidal patients showed increased connectivity in the left cerebellum and the left lingual gyrus and decreased connectivity in the right precuneus. No differences in the scores of any clinical scales were found between the suicidal and non suicidal depressed patients. CONCLUSIONS: Collectively, our results highlight the importance of the DMN in the pathophysiology of depression and suggest that suicidal behavior in depressed adolescents may be related to abnormal functional connectivity in the DMN. In particular, abnormal connectivity in the PCC/precuneus and left cerebellum might be a predictor of suicidal behavior in depressed adolescent patients. PMID- 27688125 TI - Opioid-Sparing Effect of Ketamine in Children: A Meta-Analysis and Trial Sequential Analysis of Published Studies. AB - INTRODUCTION: Reducing postoperative opioid consumption is a priority given its impact upon recovery, and the efficacy of ketamine as an opioid-sparing agent in children is debated. The goal of this study was to update a previous meta analysis on the postoperative opioid-sparing effect of ketamine, adding trial sequential analysis (TSA) and four new studies. MATERIALS AND METHODS: A comprehensive literature search was conducted to identify clinical trials that examined ketamine as a perioperative opioid-sparing agent in children and infants. Outcomes measured were postoperative opioid consumption to 48 h (primary outcome: postoperative opioid consumption to 24 h), postoperative pain intensity, postoperative nausea and vomiting and psychotomimetic symptoms. The data were combined to calculate the pooled mean difference, odds ratios or standard mean differences. In addition to this classical meta-analysis approach, a TSA was performed. RESULTS: Eleven articles were identified, with four added to seven from the previous meta-analysis. Ketamine did not exhibit a global postoperative opioid-sparing effect to 48 postoperative hours, nor did it decrease postoperative pain intensity. This result was confirmed using TSA, which found a lack of power to draw any conclusion regarding the primary outcome of this meta analysis (postoperative opioid consumption to 24 h). Ketamine did not increase the prevalence of either postoperative nausea and vomiting or psychotomimetic complications. CONCLUSIONS: This meta-analysis did not find a postoperative opioid-sparing effect of ketamine. According to the TSA, this negative result might involve a lack of power of this meta-analysis. Further studies are needed in order to assess the postoperative opioid-sparing effects of ketamine in children. PMID- 27688128 TI - Monitored anesthetic care and cataract surgery.

PMID- 27688126 TI - Brain omega-3 polyunsaturated fatty acids modulate microglia cell number and morphology in response to intracerebroventricular amyloid-beta 1-40 in mice. AB - BACKGROUND: Neuroinflammation is a proposed mechanism by which Alzheimer's disease (AD) pathology potentiates neuronal death and cognitive decline. Consumption of omega-3 polyunsaturated fatty acids (PUFA) is associated with a decreased risk of AD in human observational studies and exerts protective effects on cognition and pathology in animal models. These fatty acids and molecules derived from them are known to have anti-inflammatory and pro-resolving properties, presenting a potential mechanism for these protective effects. METHODS: Here, we explore this mechanism using fat-1 transgenic mice and their wild type littermates weaned onto either a fish oil diet (high in n-3 PUFA) or a safflower oil diet (negligible n-3 PUFA). The fat-1 mouse carries a transgene that enables it to convert omega-6 to omega-3 PUFA. At 12 weeks of age, mice underwent intracerebroventricular (icv) infusion of amyloid-beta 1-40. Brains were collected between 1 and 28 days post-icv, and hippocampal microglia, astrocytes, and degenerating neurons were quantified by immunohistochemistry with epifluorescence microscopy, while microglia morphology was assessed with confocal microscopy and skeleton analysis. RESULTS: Fat-1 mice fed with the safflower oil diet and wild type mice fed with the fish oil diet had higher brain DHA in comparison with the wild type mice fed with the safflower oil diet. Relative to the wild type mice fed with the safflower oil diet, fat-1 mice exhibited a lower peak in the number of labelled microglia, wild type mice fed with fish oil had fewer degenerating neurons, and both exhibited alterations in microglia morphology at 10 days post-surgery. There were no differences in astrocyte number at any time point and no differences in the time course of microglia or astrocyte activation following infusion of amyloid-beta 1-40. CONCLUSIONS: Increasing brain DHA, through either dietary or transgenic means, decreases some elements of the inflammatory response to amyloid-beta in a mouse model of AD. This supports the hypothesis that omega-3 PUFA may be protective against AD by modulating the immune response to amyloid-beta. PMID- 27688130 TI - Lung isolation in thoracic anesthesia, state of the art. AB - Although the incidence of cases with the original indications for lung isolation such as abscess and hemoptysis has decreased, lung isolation is required with increasing frequency in an ever-widening spectrum of clinical situations. The preference of anesthesiologists has oscillated between bronchial blockers and single or double-lumen tubes for the past 50 yr. At present, double-lumen tubes continue to have the widest application for providing safe reliable lung separation in the majority of cases. However the optimal method of lung isolation in any individual case will depend on multiple factors which include the patient's underlying pathology and anatomy and the skill and training of the anesthesiologist.

PMID- 27688134 TI - Trauma in pregnancy. AB - CONCLUSION: An exhaustive review of the care of the pregnant trauma patient would fill a book. Nevertheless, an understanding of the normal physiologic changes of pregnancy is virtually all there is to go on except in a few special situations such as listed above. Close communication with critical care, surgical and obstetrical colleagues are essential. This is certainly a clinical situation where a truly multi-disciplinary approach brings positive results. With this is mind it should be possible to confidently care for these special patients. PMID- 27688135 TI - Anesthesia and the progress of labour. AB - CONCLUSIONS: The last decade has seen a remarkable advance in our understanding of the effects of regional analgesia on the progress and outcome of labour. In particular, the appearance of several well conducted prospective, randomized trials have helped confirm the opinion of most anesthesiologists and a growing number of obstetricians, that epidural analgesia only minimally lengthens labour and does not increase the risk of cesarean section. But the extraordinary methodological complexities of studying this unblindable treatment in patients who are anything but ambivalent about whether or not they receive it ensures the debate will continue. It is perhaps time to move away from outcome studies and on to investigations of the putative mechanisms of any effects epidural analgesia may have on the labour and delivery process. It is also vital to place greater emphasis on the interaction between obstetrical practice, analgesic technique, and the patient. There may be important differences between subsets of patients with regard to their risk of cesarean section and the effect epidural analgesia may have on this risk. This is almost certainly true for certain obstetrical practices. Only by an appreciation of the actual physiology of epidural analgesia in the context of obstetrical care and the labour process itself will one of the longest running debates in anesthesiology come to an end.

PMID- 27688140 TI - Gaining control: can we reduce perioperative cardiovascular complications? AB - Cardiovascular complications are common in patients at risk for coronary disease undergoing surgery. The role of hyperactivity of the sympathetic nervous system and impaired parasympathetic control mechanisms in the genesis and consequences of perioperative myocardial ischemia has been discussed. Sympathetic blocking drugs of the beta blocker and alpha2 agonist classes have been used extensively in the perioperative setting to control hemodynamic responses and reduce episodes of myocardial ischemia. To date, perioperative beta blockade is the only strategy shown to improve long-term outcome after surgery in this population.

AB - CONCLUSION: Despite profound advances in anesthesia care, feeding techniques, and drug development, the catabolic response to injury still represents a metabolic phenomenon in surgical patients, which deserves the attention of clinicians and researchers. Although there is evidence that single pharmacological interventions are able to modulate protein catabolism, nitrogen losses following surgery cannot be completely suppressed and organ function promptly restored. We believe that multimodal approaches combining analgesic, anesthetic and surgical strategies with the provision of specific nutrients and anabolic agents hold great promise for not only reducing the loss of body protein, but also for accelerating recovery, shortening the length of hospitalization, and reducing convalescence resulting in a major improvement in clinical outcome. Furthermore, the use of tracer methodologies will further increase our understanding of the pathophysiological changes induced by tissue trauma and will help to identify subgroups of patients who might particularly benefit from our therapeutical efforts.

PMID- 27688143 TI - Effects of Karate Training Versus Mindfulness Training on Emotional Well-Being and Cognitive Performance in Later Life. AB - In a randomized controlled trial, we investigated the effects of karate versus a mindfulness-based stress reduction (MBSR) intervention on well-being and cognitive functioning in older adults. Fifty-five adults (52-81 years old) participated in twice-weekly karate versus MBSR sessions or no training for 8 weeks. In pre- and postassessments, subjective well-being, health, cognitive functioning, and chronic stress were measured. Preassessment hair cortisol served as physiological stress marker. The results showed an improvement for the karate group, but not the MBSR and control group, in subjective mental health and anxiety as well as cognitive processing speed. The MBSR group showed by trend as a decrease in stress. No significant correlation between preassessment hair cortisol and postassessment outcomes could be established. But the higher the level of baseline self-reported perceived stress, the higher the increase in depression, anxiety, and chronic stress. Generally, it can be assumed that karate and MBSR showed only small training effects concerning the assessed emotional and cognitive parameters. PMID- 27688147 TI - Bleomycin-induced skin toxicity: is it always flagellate erythema? AB - Bleomycin-induced skin toxicity is a rare and unique complication. We report a 35 year-old man with nodular lymphocytic predominant Hodgkin's lymphoma, stage IVB, who was started on adriamycin, bleomycin, vinblastin and dacarbazine (ABVD) chemotherapy. He developed pruritic hyperpigmented, patchy skin lesions on the neck, back, chest and thighs after IA cycle of ABVD chemotherapy. Lesions were not typical flagellate rash but hyperpigmented, patchy and mildly pruritic lesions over the trunk and proximal extremities. Lesions increased with continuation of bleomycin and improved gradually after removing the drug from chemotherapy schedule. The patient was in complete remission after VI cycles of chemotherapy (AVD Regimen) and skin lesions healed with minimal residual hyperpigmentation. PMID- 27688144 TI - Sex Disparities in Adverse Childhood Experiences and HIV/STIs: Mediation of Psychopathology and Sexual Behaviors. AB - HIV and other sexually transmitted infections (STIs) are important public health challenges in the US. Adverse childhood experiences (ACEs), including abuse (emotional, physical or sexual), witnessing violence among household members, may have an effect on sexual behaviors, which increase the risk of HIV/STIs. The aim of this study was to examine the sex differences in the role of posttraumatic stress disorder (PTSD), major depression (MD), substance use disorders (SUDs), early sexual debut, and intimate partner violence (IPV) perpetration as mediators in the association between ACEs and HIV/STIs. Data were obtained from Wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions. Structural equation modeling was used to determine the role of PTSD, MD, SUDs, early sexual debut, and IPV perpetration as mediators in the relationships between ACEs and HIV/STIs. Differences and similarities existed in the mediational roles of psychopathology and sexual behaviors. For example, among men, MD fully mediated physical/psychological abuse (beta = 0.0002; p = 0.012) and sexual abuse (beta = 0.0002; p = 0.006), and HIV/STIs while among women, MD fully mediated physical/psychological abuse (beta = 0.0005; p < 0.001) and parental violence (beta = -0.0002; p = 0.012). Among men, IPV perpetration fully mediated sexual abuse (beta = -0.0005; p = 0.012) and HIV/STIs while among women, IPV perpetration was not a statistically significant mediator. HIV/STI prevention and intervention programs should use a life course approach by addressing adverse childhood events among men and women and consider the sex differences in the roles of psychopathology and sexual behaviors. PMID- 27688146 TI - Assessment of diagnostic doses for widely used synthetic pyrethroids (Deltamethrin & Permethrin) in an endemic focus of leishmaniasis in Turkey. AB - BACKGROUND: Leishmania is a group of parasitic flagellated protozoons, which are transmitted by female sand flies and produces health problems in humans and also in wild and domestic animals. So far, 25 Phlebotomus and 4 Sergentomyia species were recorded in Turkey including proven or possible vectors of Leishmania spp. As no single insecticide susceptibility test was conducted targeting the sand flies in Turkey, we aimed to determine the diagnostic dose against two commonly used synthetic pyrethroids (deltamethrin and permethrin) in a hyperendemic area for leishmaniasis. METHODS: Sand flies were collected from villages of Adana in 2 4 September 2013 using Centers for Disease Control and Prevention (CDC) light traps and transferred to the laboratory. The World Health Organisation tube test method was conducted using self-prepared filter papers with different concentrations. In order to determine the diagnostic dose, lethal doses (LD) were calculated by EPA Probit Analysis. Sand flies used in the experiments were dissected, mounted and identified. RESULTS: For the lowest (0.025 %) and highest dose of permethrin (0.5 %), the mortality rate was recorded as 52.6 % and 100 % by the end of 24-h period and the diagnostic dose was recorded as 0.36 %. The mortality rate for lowest (0.0025 %) and highest (0.05 %) doses of deltamethrin was recorded as 54.8 % and 100 %. The diagnostic dose of deltamethrin was determined as 0.9 %. CONCLUSION: An insecticide susceptibility study was conducted in Turkey for the first time and effective doses were determined by calculating the LDs. According to presented results, the wild population of sand flies collected from a hyper-endemic region of Adana Province is still susceptible to deltamethrin and permethrin. PMID- 27688145 TI - Large-scale characterization study of patients with antimitochondrial antibodies but nonestablished primary biliary cholangitis. AB - : The prevalence, clinical characteristics, and outcomes of patients with antimitochondrial antibodies (AMAs), but no clinical evidence of primary biliary cholangitis (PBC), are largely unknown. A prospective study of AMA incidence was conducted through a nation-wide network of 63 French immunology laboratories. Clinical data from 720 of 1,318 AMA-positive patients identified in 1 year were collected. Patients were categorized as either newly diagnosed with PBC (n = 275), previously diagnosed with PBC (n = 216), or with nonestablished diagnosis of PBC (n = 229). The latter group was specifically evaluated. Follow-up data were collected for up to 7 years after detection of AMAs. Prevalence of AMA positive patients without evidence of PBC was 16.1 per 100,000. These patients had the following characteristics: 78% female; median age 58 years; median AMA titer 1:160; extrahepatic autoimmune disorders 46%; normal serum alkaline phosphatases (ALP) 74%; ALP above 1.5 times the upper limit of normal 13%; and cirrhosis 6%. Compared to those newly diagnosed with PBC, the patients were slightly younger, had lower AMA titers, and lower sex-ratio imbalance. Among the patients with normal ALP and no evidence of cirrhosis, the 5-year incidence rate of PBC was 16%. Whereas no patients died from PBC, the 5-year survival rate was 75%, as compared to 90% in a control, standardized population matched for age and sex (P < 0.05). CONCLUSION: Nearly half of the newly detected AMAs in clinical practice does not lead to a diagnosis of PBC. PBC is unrecognized in 13% of those cases. Only 1 in 6 patients with AMAs and normal ALP will develop PBC after 5 years. The mortality of AMA-positive patients without PBC is increased irrespective of the risk of PBC development.

PMID- 27688150 TI - The ACAT2 expression of human leukocytes is responsible for the excretion of lipoproteins containing cholesteryl/steryl esters. AB - Acyl-coenzymeA:cholesterol acyltransferase 2 (ACAT2) is abundantly expressed in intestine and fetal liver of healthy human. Our previous studies have shown that in monocytic cells the low-level expression of human ACAT2 gene with specific CpG hypomethylated promoter is regulated by the CCAAT/enhancer binding protein (C/EBP) transcription factors. In this study, we further report that the ACAT2 gene expression is attributable to the C/EBPs in the human leukocytes and correlated with the excretion of fluorescent lipoproteins containing the ACAT2 catalyzed NBD22-steryl esters. Moreover, this lipoprotein excretion can be inhibited by the ACAT2 isoform-selective inhibitor pyripyropene A (PPPA) in a dose-dependent manner, and employed to determine the half maximum inhibitory concentration (IC50) values of PPPA. Significantly, it is found that the differentiation-inducing factor all-trans retinoic acid, but not the proinflammatory cytokine tumor necrosis factor-alpha, enhances this ACAT2 dependent lipoprotein excretion. These data demonstrate that the ACAT2 expression of human leukocytes is responsible for the excretion of lipoproteins containing cholesteryl/steryl esters (CE/SE), and suggest that the excretion of lipoproteins containing the ACAT2-catalyzed CS/SE may avoid cytotoxicity through decreasing the excess intracellular cholesterols/sterols (especially various oxysterols), which is essential for the action of the human leukocytes. PMID- 27688152 TI - A modelling tool for capacity planning in acute and community stroke services. AB - BACKGROUND: Mathematical capacity planning methods that can take account of variations in patient complexity, admission rates and delayed discharges have long been available, but their implementation in complex pathways such as stroke care remains limited. Instead simple average based estimates are commonplace. These methods often substantially underestimate capacity requirements. We analyse the capacity requirements for acute and community stroke services in a pathway with over 630 admissions per year. We sought to identify current capacity bottlenecks affecting patient flow, future capacity requirements in the presence of increased admissions, the impact of co-location and pooling of the acute and rehabilitation units and the impact of patient subgroups on capacity requirements. We contrast these results to the often used method of planning by average occupancy, often with arbitrary uplifts to cater for variability. METHODS: We developed a discrete-event simulation model using aggregate parameter values derived from routine administrative data on over 2000 anonymised admission and discharge timestamps. The model mimicked the flow of stroke, high risk TIA and complex neurological patients from admission to an acute ward through to community rehab and early supported discharge, and predicted the probability of admission delays. RESULTS: An increase from 10 to 14 acute beds reduces the number of patients experiencing a delay to the acute stroke unit from 1 in every 7 to 1 in 50. Co-location of the acute and rehabilitation units and pooling eight beds out of a total bed stock of 26 reduce the number of delayed acute admissions to 1 in every 29 and the number of delayed rehabilitation admissions to 1 in every 20. Planning by average occupancy would resulted in delays for one in every five patients in the acute stroke unit. CONCLUSIONS: Planning by average occupancy fails to provide appropriate reserve capacity to manage the variations seen in stroke pathways to desired service levels. An appropriate uplift from the average cannot be based simply on occupancy figures. Our method draws on long available, intuitive, but underused mathematical techniques for capacity planning. Implementation via simulation at our study hospital provided valuable decision support for planners to assess future bed numbers and organisation of the acute and rehabilitation services.

AB - Acyl-coenzyme A:cholesterol acyltransferases (ACATs) are the exclusive intracellular enzymes that catalyze the formation of cholesteryl/steryl esters (CE/SE). In our previous work, we found that the high-level expression of human ACAT2 gene with the CpG hypomethylation of its whole promoter was synergistically regulated by two transcription factors Cdx2 and HNF1alpha in the intestine and fetal liver. Here, we first observed that the specific CpG-hypomethylated promoter was correlated with the low expression of human ACAT2 gene in monocytic cell line THP-1. Then, two CCAAT/enhancer binding protein (C/EBP) elements within the activation domain in the specific CpG-hypomethylation promoter region were identified, and the expression of ACAT2 in THP-1 cells was evidently decreased when the C/EBP transcription factors were knock-downed using RNAi technology. Furthermore, ChIP assay confirmed that C/EBPs directly bind to their elements for low-level expression of human ACAT2 gene in THP-1 cells. Significantly, the increased expressions of ACAT2 and C/EBPs were also found in macrophages differentiated from both ATRA-treated THP-1 cells and cultured human blood monocytes. These results demonstrate that the low-level expression of human ACAT2 gene with specific CpG-hypomethylated promoter is regulated by the C/EBP transcription factors in monocytic cells, and imply that the lowly expressed ACAT2 catalyzes the synthesis of certain CE/SE that are assembled into lipoproteins for the secretion.

AB - In the case of high valuable individuals with very precious genetic material, widening the genetic pool including gametes with poor morphological characteristics, as cumulus-denuded oocytes (CDOs), could be an option. To improve the in vitro culture of low-competence feline CDOs, an enriched three dimensional (3D) system in association with competent cumulus-oocyte complexes (COCs) was developed. For this purpose, domestic cat CDOs were cultured with or without companion COCs in the 3D barium alginate microcapsules. The overall viability and the meiotic progression of feline CDOs cocultured with COCs or cultured separately in 3D or in 2D (traditional microdrops) system were compared. The 3D system was able to support viability and meiotic resumption of the feline oocytes, as well as the 2D microdrops. In 3D microcapsules, the presence of COCs resulted in a higher viability of CDOs (91.1%, p < .05), than that obtained without COCs or in 2D microdrops (71.2% and 67.3%, respectively), but the percentages of meiotic resumption were similar of those of CDOs cultured separately (55.4% vs. 40.4%, p > .05). It is notable that the presence of CDOs seemed to enhance the meiotic progression of the associated COCs. In conclusion, the 3D barium alginate microcapsules are a suitable system for feline oocytes in vitro culture, but more specific enriched conditions should be developed to improve the CDOs full competence in vitro. PMID- 27688154 TI - Multiplexed MRM-based assays for the quantitation of proteins in mouse plasma and heart tissue. AB - The mouse is the most commonly used laboratory animal, with more than 14 million mice being used for research each year in North America alone. The number and diversity of mouse models is increasing rapidly through genetic engineering strategies, but detailed characterization of these models is still challenging because most phenotypic information is derived from time-consuming histological and biochemical analyses. To expand the biochemists' toolkit, we generated a set of targeted proteomic assays for mouse plasma and heart tissue, utilizing bottom up LC/MRM-MS with isotope-labeled peptides as internal standards. Protein quantitation was performed using reverse standard curves, with LC-MS platform and curve performance evaluated by quality control standards. The assays comprising the final panel (101 peptides for 81 proteins in plasma; 227 peptides for 159 proteins in heart tissue) have been rigorously developed under a fit-for-purpose approach and utilize stable-isotope labeled peptides for every analyte to provide high-quality, precise relative quantitation. In addition, the peptides have been tested to be interference-free and the assay is highly multiplexed, with reproducibly determined protein concentrations spanning >4 orders of magnitude. The developed assays have been used in a small pilot study to demonstrate their application to molecular phenotyping or biomarker discovery/verification studies. PMID- 27688155 TI - Sex and gender affect the social brain: Beyond simplicity. AB - As the most fascinating, complex, and dynamic part of our organism, the human brain is shaped by many interacting factors that not only are of neurobiological (including sex hormones) and environmental origin but are also sociocultural in their very nature (such as social roles). Gender is one of these factors. Most neurological, neurodevelopmental, neuropsychiatric, and psychosomatic disorders are characterized by impairments in visual social cognition (primarily body language reading and face perception) and a skewed sex ratio: females and males are affected differently in terms of clinical picture, prevalence, and severity. Is the social brain sex specific? This is still an open question. For a long time and for many reasons, sex differences have been overlooked or entirely ignored in neuroscience and biomedical research: there is a paucity of neuroimaging work examining sex differences in the social brain. However, the pattern of experimental behavioral data in both healthy, typically developing individuals and patients with deficient social cognition is beyond simple interpretation: contrary to popular wisdom, females are not always more proficient in understanding social signals, and their social abilities may be particularly affected by disease. Clarification of how neurobiological sex and sociocultural gender affect the social brain would provide novel insights into understanding gender-specific vulnerability to neuropsychiatric disorders. This interaction is far beyond simplicity. Although sex differences represent a rather delicate topic, underestimation or exaggeration of possible effects retards progress in the field.

AB - Mesenchymal stem cells (MSCs) are a populace of non-haematopoietic multipotent stromal cells, which have the ability to differentiate into tissue derived from a single germ layer. MSCs have been isolated from various sites, including adipose tissue, skeletal muscle, synovium, spleen, thymus, lung and amniotic fluid, but are most often isolated from bone marrow. MSCs have several valuable functions that make them a promising therapeutic option in the field of regenerative medicine, including the secretion of anti-inflammatory cytokines and growth factors, the migration of cells to the site of injury when administered and the ability to 'rescue' cells through the transfer of functional mitochondria. They also offer the possibility of autologous cell transplantation, circumventing immune rejection. These properties, among others, make MSCs a promising potential therapeutic agent in the treatment of chronic lung diseases with high rates of morbidity and mortality, such as idiopathic pulmonary fibrosis (IPF), COPD and obstructive bronchiolitis (OB). Numerous animal models have shown the protective and reparative effects of MSCs in models of experimental lung injury. There are currently several clinical trials underway to evaluate the safety and efficacy of MSCs in the treatment of IPF, COPD and OB. While early results are encouraging, a considerable amount of research must be done concerning the safety MSCs, as well as their optimal dosage, time and route of administration. In addition, much is still unknown about the pathogenesis of these chronic lung diseases, as well as the mechanisms MSCs utilize to assist in their repair. PMID- 27688157 TI - Clinical spectrum and diagnostic pitfalls of multiple abnormal uptakes on bone scintigraphy. AB - Bone scintigraphy with technetium-99m (99mTc)-labeled diphosphonates is one of the most frequently performed radionuclide procedures. Accumulation of 99mTc labeled diphosphonate is well recognized to reflect conditions of accelerated bone turnover and metabolism. Therefore, it is a functional imaging modality for detecting metastatic bone tumors, metabolic bone disease, traumatic injury, and inflammation. This pictorial essay describes the possible patterns of distribution of abnormal uptake for differential diagnosis of metastatic bone tumor, as well as the diagnostic pitfalls of bone scintigraphy. PMID- 27688158 TI - Clinicopathological features and outcomes in patients with late recurrence of renal cell carcinoma after radical surgery. AB - OBJECTIVES: To characterize patients experiencing late recurrence after primary radical surgery for renal cell carcinoma and to approach the mechanism of late recurrence. METHODS: We retrospectively analyzed 657 consecutive patients who underwent radical surgery for pathologically confirmed <=stage III renal cell carcinoma in a single institution between January 1981 and December 2008. Early or late recurrence was defined as a recurrence occurring before or after 60 months after primary surgery. RESULTS: Of 657 patients, 96 (14.6%) experienced early recurrence, and 41 (6.2%) developed late recurrence. Patients with late recurrence had smaller diameter of primary tumor (median 5 cm vs 8 cm, P < 0.001), lower pathological stage (P < 0.001) and lower nuclear grade (P = 0.004) at primary surgery than those with early recurrence. On multivariate analysis, vascular invasion (including microscopic and gross invasion) was the predictor of late recurrence (P < 0.01, HR 3.79). Overall survival and disease-specific survival after recurrence were longer in patients with late recurrence (median 64 and 76 months, respectively) than in those with early recurrence (34.5 and 35 months, respectively; P = 0.008 and 0.002). CONCLUSIONS: These results suggest that micrometastasis at the time of surgery associated with vascular invasion at primary tumor site and their relatively lower malignant potential could lead to late recurrence. Further studies are warranted for better understanding and managing late recurrence of renal cell carcinoma. PMID- 27688159 TI - Safety and seizure control in patients with mesial temporal lobe epilepsy treated with regional superselective intra-arterial injection of autologous bone marrow mononuclear cells. AB - Temporal lobe epilepsy (TLE) is a highly prevalent syndrome among people with epilepsy, and is usually refractory to drug treatment. Structural and physiological changes, such as hippocampal sclerosis, are often present in TLE patients. The objective of this study is to evaluate the feasibility and safety of intra-arterial infusion of autologous bone marrow mononuclear cells (BMMC) in adults with medically refractory mesial TLE (MTLE) and unilateral hippocampal sclerosis (HS). We enrolled 20 patients who had been diagnosed with MTLE-HS and were refractory to medical treatment. All patients underwent a neurological evaluation, magnetic resonance imaging with hippocampal volumetry, video electroencephalography (EEG) with ictal recording, and a neuropsychological test battery focusing on verbal and nonverbal memory domains. After bone marrow aspiration and subsequent cell preparation, the BMMC were infused by selective posterior cerebral artery catheterization. Patients were followed for 6 months. Safety of the procedure, seizure frequency, neuropsychological evaluation, EEG variables, routine brain magnetic resonance imaging and hippocampal volumetry were considered measurements of outcome. Any serious intercurrent clinical event or adverse effects related to the procedure were reported. No additional lesions and no significant hippocampal volumetric changes were observed. EEG recordings showed a decrease in theta activity and spike density. At 6 months, eight patients (40%) were seizure free. A significant increase in the memory scores over time was observed. The BMMC autologous transplant for the treatment of temporal lobe epilepsy is feasible and safe. The seizure control achieved in this novel study supports the therapeutic potential of stem cell transplants in MTLE HS patients. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27688160 TI - Effects of plantar stimulation on cardiovascular response to orthostatism. AB - PURPOSE: Walking is a complex locomotor process that involves both spinal cord reflexes and cortical integration of peripheral nerve input. Maintaining an upright body position requires not only neuromuscular activity but also cardiovascular regulation. We postulated that plantar mechanical stimulation might modulate autonomic nervous system activity and, thereby, impact blood pressure adaptation during standing. METHODS: Twelve healthy subjects underwent three randomly ordered 45-min 70 degrees -saddle tilt tests while the plantar surfaces of the feet were stimulated using specially engineered Korvit boots in the following modes: (1) no stimulation, (2) disrupted stimulation, and (3) walking mode. Orthostatic tolerance time was measured for each trial. During testing, we obtained an electrocardiogram and measured blood pressure, skin blood flow, and popliteal vein cross-sectional area. We estimated central hemodynamics, baroreflex sensitivity and heart rate variability. RESULTS: Orthostatic tolerance time was not found to differ significantly between test conditions (37.2 +/- 10.4, 40.9 +/- 7.6, and 41.8 +/- 8.2 min, for no stimulation, disrupted stimulation, and walking mode, respectively). No significant differences between treatment groups were observed for stroke volume or cardiac baroreflex sensitivity, both of which decreased significantly from baseline during tilt testing in all groups. Cardiac sympathetic index and popliteal vein cross sectional area increased at the end of the tilt period in all groups, without significant differences between treatments. CONCLUSIONS: Plantar mechanical stimulation is insufficient for immediate modulation of cardiac sympathetic and parasympathetic activity under orthostatic stress. PMID- 27688161 TI - Prenatal Alcohol Exposure and Pair Feeding Differentially Impact Puberty and Reproductive Development in Female Rats: Role of the Kisspeptin System. AB - BACKGROUND: Reproductive maturation is initiated with the onset of puberty, which activates the hypothalamic-pituitary-gonadal axis and coincidences with increased expression of the hormone kisspeptin within the hypothalamus. Maturational events are sensitive to environmental factors, including alcohol, which is known to delay reproductive development. We hypothesized that, similar to alcohol's adverse effects during reproductive maturation, prenatal alcohol exposure (PAE) would alter pubertal markers, sex hormone profiles, and kisspeptin expression in the hypothalamus. METHODS: Female offspring from control (C), pair-fed (PF), and PAE groups were sacrificed prior to puberty onset (postnatal day [PND] 30), during puberty [PND 35], or in adulthood [PND 65]. Estradiol (E2 ), progesterone (P4 ), prolactin, and luteinizing hormone levels, and Kiss1 mRNA expression were measured in the arcuate (ARC) and anteroventral periventricular (AVPV) nuclei of the hypothalamus. Pubertal markers (vaginal opening [VO], uterus/body wt ratio) were assessed. RESULTS: Our findings indicate that (i) PAE inhibits the expected increases in E2 levels with age and delays maturational increases of P4 levels; (ii) PAE and pair feeding have similar adverse effects on VO and uterus/body wt ratio; (iii) differential relationships between PRL and P4 suggest that different mechanisms may underlie delayed maturation in PAE and PF; that is, PF females have low PRL levels and no increase in P4 with age, whereas PAE animals, despite low PRL, show the expected age-related increase in P4 ; and (iv) there is higher mean density of Kiss1 mRNA in the ARC of adult PAE females and altered Kiss1 expression in the AVPV of both PAE and PF females. CONCLUSIONS: PAE and pair feeding have some overlapping but important differential effects on hormonal profiles and Kiss1 mRNA expression during reproductive development. Preadolescent alterations in Kiss1 expression in the AVPV and ARC, which may change the balance of function in these 2 nuclei, may differentially contribute to delayed reproductive maturation in PAE and PF compared to C females. PMID- 27688162 TI - Phase I/II trial of combination of temozolomide chemotherapy and immunotherapy with fusions of dendritic and glioma cells in patients with glioblastoma. AB - BACKGROUND: This trial was designed to evaluate the safety and clinical responses to a combination of temozolomide (TMZ) chemotherapy and immunotherapy with fusions of DCs and glioma cells in patients with glioblastoma (GBM). METHOD: GBM patients were assigned to two groups: a group of recurrent GBMs after failing TMZ chemotherapy against the initially diagnosed glioma (Group-R) or a group of newly diagnosed GBMs (Group-N). Autologous cultured glioma cells obtained from surgical specimens were fused with autologous DCs using polyethylene glycol. The fusion cells (FC) were inoculated intradermally in the cervical region. Toxicity, progression-free survival (PFS), and overall survival (OS) of this trial were evaluated. Expressions of WT-1, gp-100, and MAGE-A3, recognized as chemoresistance-associated peptides (CAP), were confirmed by immunohistochemistry of paraffin-embedded tumor samples. Patient's PBMCs of pre- and post-vaccination were evaluated by tetramer and ELISPOT assays. RESULTS: FC-immunotherapy was well tolerated in all patients. Medians of PFS and OS of Group-R (n = 10) were 10.3 and 18.0 months, and those of Group-N (n = 22) were 18.3 and 30.5 months, respectively. Up-regulation and/or cytoplasmic accumulation of CAPs was observed in the recurrent tumors of Group-R patients compared with their initially excised tumors. Specific immune responses against CAPs were observed in the tetramer and ELISPOT assays. CONCLUSIONS: The combination of TMZ-treatment leading to up regulation and/or cytoplasmic accumulation of CAPs, with FC-immunotherapy as a means of producing specific immunity against CAPs, may safely induce anti-tumor effects in patients with GBM. PMID- 27688163 TI - Predicting PD-L1 expression on human cancer cells using next-generation sequencing information in computational simulation models. AB - PURPOSE: Interaction of the programmed death-1 (PD-1) co-receptor on T cells with the programmed death-ligand 1 (PD-L1) on tumor cells can lead to immunosuppression, a key event in the pathogenesis of many tumors. Thus, determining the amount of PD-L1 in tumors by immunohistochemistry (IHC) is important as both a diagnostic aid and a clinical predictor of immunotherapy treatment success. Because IHC reactivity can vary, we developed computational simulation models to accurately predict PD-L1 expression as a complementary assay to affirm IHC reactivity. METHODS: Multiple myeloma (MM) and oral squamous cell carcinoma (SCC) cell lines were modeled as examples of our approach. Non transformed cell models were first simulated to establish non-tumorigenic control baselines. Cell line genomic aberration profiles, from next-generation sequencing (NGS) information for MM.1S, U266B1, SCC4, SCC15, and SCC25 cell lines, were introduced into the workflow to create cancer cell line-specific simulation models. Percentage changes of PD-L1 expression with respect to control baselines were determined and verified against observed PD-L1 expression by ELISA, IHC, and flow cytometry on the same cells grown in culture. RESULT: The observed PD-L1 expression matched the predicted PD-L1 expression for MM.1S, U266B1, SCC4, SCC15, and SCC25 cell lines and clearly demonstrated that cell genomics play an integral role by influencing cell signaling and downstream effects on PD-L1 expression. CONCLUSION: This concept can easily be extended to cancer patient cells where an accurate method to predict PD-L1 expression would affirm IHC results and improve its potential as a biomarker and a clinical predictor of treatment success. PMID- 27688165 TI - Upregulation of SIRT1-AMPK by thymoquinone in hepatic stellate cells ameliorates liver injury. AB - Thymoquinone (TQ) is a biologically active compound isolated from the seeds of Nigella sativa L. (Ranuculaceae). This study investigated the hepato-protective effect of TQ on liver injury through AMP-activated protein kinase (AMPK) signaling in hepatic stellate cells (HSCs). In vitro, TGF-beta time-dependently attenuated liver kinase B-1 (LKB1) and AMPK phosphorylation, which were blocked by pretreatment with TQ and AICAR (an activator of AMPK). TQ significantly inhibited collagen-Iota, alpha-SMA, TIMP-1 and enhanced MMP-13 expression, contributing to prevent TGF-beta-induced human HSCs activation. Moreover, TQ induced peroxisome proliferator activated receptor-gamma (PPAR-gamma) expression, which was inhibited by genetic deletion of AMPK. In vivo, C57BL/6 mice were fed with ethanol diet for 10 days, then administering a single dose of ethanol (5g/kg body weight) via gavage. TQ (20 or 40mg/kg) were given by gavage every day. TQ attenuated the increases in serum aminotransferase and hepatic triglyceride in mice fed with ethanol, while significantly activated LKB1 and AMPK phosphorylation. In addition, TQ enhanced the sirtuin 1 (SIRT1) expression. In conclusion, we demonstrate that AMPK pathway is a key therapeutic target for controlling liver injury and TQ confers hepato-protection against TGF-beta induced the activation of HSCs and ethanol-induced liver injury. PMID- 27688166 TI - Randomised trial of bisphosphonate-coated dental implants: Radiographic follow-up after five years of loading. AB - The results of a randomised trial with bisphosphonate-coated dental implants have been reported previously. Each patient received one coated and one uncoated implant in a double-blind split-mouth design study. After 6 months of osseointegration, resonance frequency analysis indicated better fixation of the coated implants. Reduced marginal bone resorption was also shown. However, it was not known whether the advantage of the bisphosphonate coating would persist over time. The radiographic results at 5 years after implant installation are reported herein. A blinded investigator measured marginal resorption on fresh radiographs obtained for 14 of the 16 patients (two had died) and compared these with the post-implantation images. Non-parametric statistics were used. All implants functioned well. The median marginal bone loss for control implants was found to be 0.70mm, which is less than usually reported in the literature. The bisphosphonate-coated implants showed even less resorption (median 0.20mm). The median difference within each pair of implants after 5 years of use was 0.34mm (95% confidence interval 0.00-0.75mm; P=0.04). The present data suggest that bisphosphonate-coated implants enable prolonged preservation of the marginal bone. PMID- 27688164 TI - A Psycho-Educational Intervention for People with a Family History of Depression: Pilot Results. AB - We developed and pilot-tested the first online psycho-educational intervention that specifically targets people with a family history of depression ('LINKS'). LINKS provides genetic risk information and evidence-rated information on preventive strategies for depression and incorporates a risk assessment tool and several videos using professional actors. LINKS was pilot-tested in the general practitioner (GP) setting. The patient sample included people with a family history of at least one first-degree relative (FDR) with major depressive disorder (MDD) or bipolar disorder (BD). Patients attending participating GP practices were invited to enroll in the study by letter from their GP. Patients who self-identified as having at least one first-degree relative (FDR) with MDD or BD were eligible. Patients completed questionnaires, pre-post viewing LINKS, with measures assessing satisfaction, relevance, emotional impact and perceived improvement of understanding. Six GP practices participated, and 24 patients completed both questionnaires. Of these, all reported that they were satisfied or very satisfied with LINKS, and 74 % reported that LINKS met their expectations, and 21 % that it exceeded their expectations. LINKS was judged highly acceptable by this sample of GP attendees, and results indicate that an assessment of its effectiveness in a larger controlled trial is warranted. PMID- 27688167 TI - Changes in the lower lip soft tissue after bone graft harvesting from the mandibular symphysis. AB - Following the surgical release of the mentalis muscle, lip incompetence and/or an increase in lower incisor exposure may be seen due to undesirable attachment of the muscle fibres. The aim of this study was to evaluate the extent of lip ptosis, lower incisor exposure, and other soft tissue changes following bone graft harvesting from the mandibular symphysis when the mentalis muscle is reapproximated precisely to its original position. Seventeen consecutive patients who underwent bone graft harvesting from the mandibular symphysis were included in this study. The mentalis muscle was isolated, identified, marked, and reapproximated precisely during the bone harvesting operation. Digital lateral cephalograms obtained preoperatively and at 6 months postoperative were analyzed and compared by paired samples t-test to determine the horizontal and vertical soft tissue changes in the lower lip and chin. Although the soft tissue thickness at soft tissue point B and at soft tissue pogonion had increased significantly at 6 months after chin bone graft harvesting, there were no significant changes in lower incisor exposure or other positional alterations of the lower lip (P<0.05). Precise reattachment of the mentalis muscle in its original position helps to avoid significant vertical positional changes in the lower lip. Increases in soft tissue thickness can be observed following bone graft harvesting from the mandibular symphysis. PMID- 27688168 TI - Effects of surgical correction of class III malocclusion on the pharyngeal airway and its influence on sleep apnoea. AB - The objective of this study was to evaluate, through cone beam computed tomography, the immediate changes in pharyngeal airway space (PAS) after orthognathic surgery in class III patients, and to determine the influence of surgery on the development of obstructive sleep apnoea hypopnoea syndrome (OSAHS). A prospective study was conducted; 33 patients were divided into three groups: mandibular setback surgery (nine patients), bimaxillary surgery (18 patients), and maxillary advancement surgery (six patients). PAS measurements obtained pre- and postoperatively were compared using the t-test. All patients were assessed clinically for OSAHS before surgery and at 6 months postoperative using the Berlin questionnaire and a combined clinical assessment, which included the assessment of OSAHS symptoms, Epworth Sleepiness Scale score, and body mass index. Patients undergoing isolated mandibular setback surgery demonstrated a decrease in total PAS volume, in hypopharynx volume, and in minimum cross sectional area of the pharynx immediately after surgery (P<0.05). The clinical analysis did not reveal signs or symptoms of OSAHS in any of the 33 patients. Although patients who underwent mandibular setback surgery alone demonstrated a volume reduction in the PAS and a decrease in minimum cross-sectional area, these reductions were not accompanied by signs or symptoms of OSAHS. PMID- 27688169 TI - The influence of mild dysplasia at the surgical margin on the prognosis of oral squamous cell carcinoma. AB - The purpose of this study was to evaluate the clinical relevance between different margin statuses and local recurrence rate in patients undergoing primary surgical treatment for oral squamous cell carcinoma (OSCC). Five hundred and thirty-nine patients with T1-4N0M0 OSCC, who underwent surgery alone at a stomatology hospital in Nanjing, China during the years 2005-2014, were included. Tumour and margin status were assessed. Overall survival (OS), disease-free survival (DFS), and recurrence-free survival (RFS) were calculated by Kaplan Meier method. Predictors of RFS, OS, and DFS were analysed. Positive or dysplastic margins were found in the initial specimen in 20.0% of the cases. On multivariate analysis, there was no significant difference between RFS (hazard ratio (HR) 1.379, P=0.361) or DFS (HR 1.452, P=0.183) of those with mild dysplasia and those with negative margins. However, patients with mild dysplasia who did not undergo re-excision demonstrated significantly worse RFS (HR 2.286, P=0.010) and DFS (HR 2.070, P=0.014) than those with negative margins. It is concluded that there appears to be a correlation between initial mild dysplastic margins that are not subjected to re-excision and inferior RFS and DFS. Additional attention should be drawn to mild dysplasia at the initial margin in OSCC, and extended excision is suggested. PMID- 27688170 TI - Late mandibular fracture occurring in the postoperative period after third molar removal: systematic review and analysis of 124 cases. AB - Factors associated with the diagnosis, aetiology, and treatment of mandibular fractures occurring during the postoperative period following the removal of a lower third molar are discussed. The following databases were searched using specific key words: PubMed/MEDLINE, LILACS, Embase, and Scopus. The search yielded 124 cases. Sex, age, side, tooth position and angulation, bone impaction, relationship between the tooth and the inferior alveolar nerve, local pathological conditions, aetiology of the fracture, symptomatology, and time between surgery and fracture, as well as any displacement of the fracture and the treatment of the fracture, were evaluated. Data were tabulated and the chi2 statistical test was applied (P<0.05). Male patients aged >35 years, with teeth in positions II/III and B/C, complete bony impaction, and local bone-like alterations, were found to have a higher frequency of fracture and pericoronitis (P<0.05). Late fractures generally occurred between the second and fourth postoperative weeks (P<0.05). They were generally not displaced and the typical treatment was the non-surgical approach (P<0.05). It is concluded that the risk of mandibular fracture after extraction is associated with excessive ostectomy and/or local alterations. At-risk patients should be thoroughly briefed on the importance of a proper postoperative diet. PMID- 27688171 TI - A rapid and fully automatic method for the accurate determination of a wide carbon-chain range of per- and polyfluoroalkyl substances (C4-C18) in human serum. AB - A rapid and fully automatic method for determining 21 per- and polyfluoroalkyl substances (with carbon chains ranging from C4 to C18, including 13 PFCAs, 5 PFSAs, 2 Cl-PFESAs, and PFOSA) in human serum samples was developed. The HPLC parameters, Turboflow column, mobile phase, sample injection volume, loading flow rate, and sample cleanup and elution time were optimized. 25MUL serum sample was directly injected into the developed on-line Turboflow SPE HPLC-MS/MS system for analysis after dilution. Matrix effects were corrected due to the matrix removal efficiency of the Turboflow column and sufficient types of internal isotope standards that were used. The established method showed a good linearity (r2>0.99), rapid processing time (20min per sample), satisfactory recoveries (matrix spiked recoveries range from 84.6% to 114%) and precision (intra-day and inter-day RSDs ranged from 1.5% to 9.2% and from 1.1% to 7.0%, respectively). The limits of detection (LODs) of the 21 analyzed PFASs were between 0.008 and 0.19ngmL-1. The LODs of short- and long-chain PFASs, such as PFBA, PFPeA, PFHxDA, and PFODA, were 0.008, 0.022, 0.15 and 0.19ngmL-1, respectively; the spiked recoveries of these PFASs were 101, 105, 87.1, and 85.8%, respectively. Both the LODs and recoveries were better than previous studies. Further, serum PFASs concentrations detected by the presented on-line SPE method were consistent with the traditional off-line SPE method (r: 0.98-0.99), which verified the accuracy and applicability of the present method. The method shows good practical prospects in the analysis of trace per- and polyfluoroalkyl substances in human serum. PMID- 27688172 TI - Using a box instead of a column for process chromatography. AB - Columns with relatively short bed-height to diameter ratios are frequently used for process-scale chromatography applications such as biopharmaceutical purification. Non-uniform flow distribution within such columns could result in broad and poorly resolved eluted peaks, which could in turn affect purity, recovery and productivity of the process. Different strategies centered on improved column header design have been proposed for addressing this problem. This paper describes a radically different approach, i.e. the use of a chromatography box (or chromato-box) instead of a column, for addressing the challenges posed by flow mal-distribution in process-scale, packed-bed chromatography devices. The design of the chromatography box devices used in this study is based on a laterally-fed membrane chromatography (or LFMC) device, that has been described and discussed in several recent papers. The performances of two chromatography box devices were compared with their equivalent columns in terms of sharpness and asymmetry of flow-through and eluted peaks, number of theoretical plates per metre, and peak resolution in binary and ternary protein separations. In each of the above comparisons, the chromatography box devices performed better than their equivalent columns, clearly indicating their potential as an alternative in process-scale chromatography applications. PMID- 27688173 TI - Determination of glucose in human stomach cancer cell extracts and single cells by capillary electrophoresis with a micro-biosensor. AB - Bioactive species in cells can provide information about signal transduction, cell function, and the effects of disease treatment. In this article, a novel micro-biosensor was fabricated to detect glucose in individual human stomach cancer cells (MGC80-3 cells) with capillary electrophoresis (CE). We fabricated the micro-biosensors by immobilizing a single-walled carbon nanotube-glucose oxidase (GOx)-glutaraldehyde (GA) bio-composite at the palladium nanoparticle (PdNPs) modified Pt electrode. The linear concentration of glucose ranged from 2.0MUM to 1.0mM, with a detection limit of 0.5MUM. Using this method, the mean amount of glucose in MGC80-3 cell extracts and in single cells was 20.0 fmol and 20+/-6 fmol (n=10), respectively. The micro-biosensor exhibited high sensitivity, stability, and a long operating life, which are likely due to the biocompatible environment provided by BSA and GA, and the adsorption and faster electron transfer of SWNTs and PdNPs to GOx.

AB - Highly selective and efficient magnetic molecularly imprinted polymers (MMIPs) were prepared using Fe3O4@SiO2 as a magnetic supporter, 3 methacryloxypropyltrimethoxy-silane (MPS) as a silane coupling agent, DIS as a template, methacrylic acid (MAA) as a functional monomer and ethyleneglycol dimethacrylate (EGDMA) as a cross-linker for the extraction of trace residuals of the synthetic estrogen dienestrol (DIS) in seawater, which is a concern worldwide for its endocrine disruption and carcinogenic danger to human health. The obtained MMIPs were demonstrated to have spherical morphologies, core-shell structures, large binding capacities, high efficiency and selectivity. These were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and adsorption experiments. Owing to the specific binding sites, the MMIPs exhibited an almost three times higher adsorption capacity towards DIS (Qmax=4.68mgg-1) than magnetic molecularly non-imprinted polymers (MNIPs) (Qmax=1.72mgg-1). DIS in spiked seawater samples from the Weihai Bay of China was extracted and enriched by MMIPs, and satisfactory recoveries (87.3%-96.4%) with low relative standard deviation (RSD) values (2.03%-5.18%, n=5) were obtained. The limit of detection (LOD) of the method obtained was 0.16MUgL-1, and the limit of quantitation was 0.52MUgL-1 after MMIPs. No significant deterioration of the adsorption capacity of the MMIPs was observed after six rounds of regeneration. The results further demonstrated the applicability of the MMIPs method, a simple and straightforward method for the extraction and enrichment of DIS in seawater without any time-consuming procedures.

Part II: Application 1 - Large increases in isoform resolution of human transferrin by use of dual simultaneous independent gradients of pH & acetonitrile on a mixed bed (anion exchange plus reversed phase) stationary phase. AB - We have previously described a liquid chromatographic (LC) method for uncoupling controlled, wide range pH gradients and simultaneous controlled gradients of a non-buffering solute on ion exchange resins (Hirsh and Tsonev, 2012) [1]. Here we report the application of this two dimensional LC technique to the problem of resolving Human Transferrin (HT) isoforms. This important iron transporting protein should theoretically occur in several thousand glycoforms, but only about a dozen have been reported. Using dual simultaneous independent gradients (DSIGs) of acetonitrile (ACN) and pH on a mixed bed stationary phase (SP) consisting of a mixture of an anion exchange resin and a reversed phase (RP) resin we partially resolve about 60 isoforms. These are likely to be partially refolded glycoforms generated by interaction of HT with the highly hydrophobic RP SP, as well as distinct folded glycoforms. Thus this study should have interesting implications for both glycoform separation and the study of protein folding.

AB - Both 3-mercaptohexan-1-ol (3MH) and 3-mercaptohexyl acetate (3MHA) were largely studied for the last 20 years due to their pleasant olfactory notes conferred to wine. Until now, many analytical methods focused only on the free forms of both 3MH and 3MHA in wine that provided partial information in the wine aroma evolution. Our study proposes new analytical measurements which allow quantification of both free and disulfide forms of 3MH and 3MHA to better understand the redox phenomenon occurring in wines and further, to orientate wine aroma evolution. Free thiols were analyzed by an original method based on maleimide derivatization allowing in-situ disulfide reduction followed by SIDA-LC MS/MS analyses exhibiting excellent performances. Indeed, the accuracy ranged from 95 to 110% in three different wine matrices and the repeatability and intermediate reproducibility were inferior to 15% (RSD measurements). Our method exhibited very low limits of detection, which are below to 0.5ng/L and inferior to the perception thresholds of both compounds. Then, this method was applied to three different wines exposed to several oxidative conditions. On the one hand, it was demonstrated that copper sulfate treatment firstly destroyed the total amount of free 3MH to the benefit of thioether and disulfides compounds, with proportions that could be slightly modified by glutathione addition. On the other hand, oxygenation of wines resulted in partial free 3MH destruction to the benefit of thioether compounds. We proposed for the first time an innovative analysis that gives a complete picture of wine aroma, which can be really useful to winemakers to manage wine aroma evolution and to take advantage of the disulfide reservoir. PMID- 27688177 TI - Highly porous nanostructured copper foam fiber impregnated with an organic solvent for headspace liquid-phase microextraction. AB - A new headspace liquid-phase microextraction technique based on using a copper foam nanostructure substrate followed by gas chromatography-flame ionization detection was developed for the determination of volatile organic compounds in water and wastewater samples. The copper foam with highly porous nanostructured walls was fabricated on the surface of a copper wire by a rapid and facile electrochemical process and used as the extractant solvent holder. Propyl benzoate was immobilized in the pores of the copper foam coating and used for the microextraction of benzene, toluene, ethylbenzene and xylenes. The experimental parameters such as the type of organic solvent, desorption temperature, desorption time, salt concentration, sample temperature, equilibrium time and extraction time, were investigated and optimized. Under the optimum conditions, the method detection limit was between 0.06 and 0.25MUgL-1. The relative standard deviation of the method for the analytes at 4-8MUgL-1 concentration level ranged from 7.9 to 11%. The fiber-to-fiber reproducibility for three fibers prepared under the same condition was 9.3-12%. The enrichment factor was in the range of 615-744. Different water samples were analyzed for the evaluation of the method in real sample analysis. Relative recoveries for spiked tap, river and wastewater samples were in the range of 85-94%. Finally, the extraction efficiency of the method was compared with those of headspace single drop microextraction and headspace SPME with the commercial fibers.

AB - Red seabream iridovirus (RSIV) is a member of genus Megalocytivirus in the family Iridoviridae. RSIV infection causes significant economic losses of marine-fishes in East Asian countries. Grunt fin (GF) cell line has been commonly used for culturing RSIV. However, it is not suitable for definite evaluation of infectivity titer of RSIV because cells infected with RSIV are not completely cytolysed. Thus, we established a new cell line, RoBE-4, from rock bream (Oplegnathus fasciatus) eyed-egg embryos in this study. Morphologically, RoBE-4 cells were fibroblastic-like. They have been stably grown over two-years with 60 passages using Leibovitz's L-15 medium containing 10% (v/v) fetal bovine serum. RoBE-4 cells infected with RSIV exhibited cytopathic effects (CPE) with cell rounding. They were cytolysed completely after >=2 weeks of culture. Numerous RSIV particles with icosahedral morphology of approximately 122nm in diameter were observed in cytoplasmic area of infected RoBE-4 cells. The RSIV suceptibility and amount of extracellular RSIV released by RoBE-4 cells were 100 fold higher than those by GF cells. RSIV cultured with RoBE-4 cells was highly virulent to rock bream in infection experiments. Therefore, using RoBE-4 cells instead of GF cells will enable accurate and sensitive measurement of RSIV infectivity. In addition, RoBE-4 cells might be used to produce RSIV vaccine in the future with significant reduction in cost.

AB - EGFR and VEGFR-2 are involved in pathological disorders and the progression of different kinds of tumors, the combined blockade of EGFR and VEGFR signaling pathways appears to be an attractive approach to cancer therapy. In this work, a series of 4-anilinoquinazoline derivatives containing substituted diaryl urea or glycine methyl ester moiety were designed and identified as EGFR and VEGFR-2 dual inhibitors. Compounds 19i, 19j and 19l exhibited the most potent inhibitory activities against EGFR (IC50 = 1 nM, 78 nM and 51 nM, respectively) and VEGFR-2 (IC50 = 79 nM, 14 nM and 14 nM, respectively), they showed good antiproliferative activities as well. Molecular docking established the interaction of 19i with the DFG-out conformation of VEGFR-2, suggesting that they might be type II kinase inhibitors.

AB - INTRODUCTION: Evisceration is currently becoming the technique of choice in the treatment of certain eye diseases, including, among others, painful blind eye and endophthalmitis. The most widely used implants are currently the hydroxyapatite and porous polyethylene for the rehabilitation of the anophthalmic socket. OBJECTIVE: To describe the indications, type of implant material used, and complications in evisceration surgery. METHODS: A retrospective, observational, descriptive study based on clinical records of patients that underwent evisceration between 2008 and 2015 in the Instituto Fundacion Conde de Valenciana, Mexico. RESULTS: A total of 186 evisceration surgeries were performed, of which 52.7% of the patients were men. The mean age was 54 years. The right eye was eviscerated in 53% of cases, and 79.2% had a vision of no light perception. Most patients had preoperative pain. The most common diagnosis for which evisceration was performed was endophthalmitis. Phthisis bulbi was reported in 20 eyes. A primary implant was inserted in 86.81% of the cases, with 34.81% of the implants being made of porous polyethylene. Four cases showed extrusion of the implant, with 2 cases of porous polyethylene. The ocular prosthesis was tolerated in 91% of cases. There were no cases of sympathetic ophthalmia. CONCLUSION: Evisceration is shown to be a good alternative to enucleation in cases where the sclera can be preserved, showing a low incidence of sympathetic ophthalmia.

AB - A series of aliphatic and aromatic substituted 1H-1,2,3-triazole-tethered 4-amino quinoline-ferrocenylchalcone conjugates has been synthesized and evaluated for anti-plasmodial activity. The conjugates with flexible aliphatic (aminoethanol or aminopropanol) substituents on the quinoline ring showed better anti-plasmodial activities compared to those with cyclic (piperazine or aminophenol) substituents. The conjugate 17j was the most potent and non-cytotoxic, with an IC50 value of 0.37 MUM against the chloroquine-resistant W2 strain of Plasmodium falciparum. PMID- 27688181 TI - Synthesis and evaluation of C9 alkoxy analogues of (-)-stepholidine as dopamine receptor ligands. AB - Tetrahydroprotoberberine alkaloids have shown interesting polypharmacological actions at dopamine receptors and are a unique template from which to mine novel molecules with dual selective actions at D1 and D3 receptors. Such compounds will be valuable to evaluate as anti-cocaine therapeutics. Towards that eventual goal, we engaged an SAR study in which a series of C9 alkoxy analogues of the D1/D2/D3 ligand (-)-stepholidine that possessed or lacked a C12 bromo functionality, were synthesized and evaluated for affinity at dopamine D1, D2 and D3 receptors. We found that the analogues are generally selective for the D1 receptor. Small n alkoxy substituents (up to 4 carbons in length) were generally well tolerated for high D1 affinity but such groups reduced D3 affinity. In the case of C12 brominated analogues, C9 alkoxylation also had little effect on D1 affinity for the smaller alkoxy groups, but reduced D2 and D3 affinities significantly. C12 bromination tends to increase D1 receptor selectivity. A number of compounds were identified that retain affinity for D1 and D3 receptors but lack D2 receptor affinity. Among them, compound 22a was found to be a selective D1/D3 dual antagonist (Ki = 5.3 and 106 nM at D1 and D3 receptors). Docking studies performed on the analogues at the D3 receptor revealed a number of interactions that are important for affinity including a critical N - Asp110 salt bridge motif, H-bonds to Ser192 and Cys181 and hydrophobic interactions between the aryl rings and Phe106 and Phe345. The analogues adopt an orientation in which ring A is located in the orthosteric binding site while the C9 alkoxy substituents attached to ring D project into the secondary binding pocket of the D3 receptor. PMID- 27688183 TI - Identification of novel microsomal prostaglandin E2 synthase-1 (mPGES-1) lead inhibitors from Fragment Virtual Screening. AB - Identification of new microsomal prostaglandin E2 synthase-1 (mPGES-1) inhibitors is currently sought for the treatment of cancer and inflammation. Here we show the results of a Fragment Virtual Screening campaign using the X-ray crystal structure of human mPGES-1 (PDB code: 4AL0). Among the fragments selected and biologically tested, 6 (9H-indeno [1,2-b] [1,2,5]oxadiazolo [3,4-e]pyrazin-9-one) showed the most promising mPGES-1 inhibitory activity (~30% inhibition at 10 MUM). A minimal structure-based optimization of 6 led to compounds 15, 20 and 21, with a promising enhancement of the inhibitory activity (IC50 = 4.6 +/- 0.2 MUM for 15; IC50 = 2.4 +/- 1.0 MUM for 20; IC50 = 2.4 +/- 0.8 MUM for 21). The unprecedented chemical core and the possibility of synthesizing novel derivatives reveal a new and attractive field of action for the development of mPGES-1 inhibitors with potential anti-inflammatory and anticancer properties. PMID- 27688184 TI - New azepino[4,3-b]indole derivatives as nanomolar selective inhibitors of human butyrylcholinesterase showing protective effects against NMDA-induced neurotoxicity. AB - Several 6-substituted 3,4,5,6-tetrahydroazepino[4,3-b]indol-1(2H)-one (THAI) derivatives were synthesized and evaluated for their activity as cholinesterase (ChE) inhibitors. The most potent inhibitors were identified among 6-(2 phenylethyl)-THAI derivatives, and in particular compounds 12b and 12d proved to be very active against human BChE (IC50 = 13 and 1.8 nM, respectively), with 1000 fold selectivity over AChE. Structure-activity relationships highlighted critical features (e.g., ring fusion [4,3-b], integrity of the lactam CONH function) and favorable physicochemical properties of the 6-(2-phenylethyl) group (i.e., optimal position, size and lipophilicity of phenyl substituents). The effects of a number of compounds against NMDA-induced SH-SY5Y neuronal cell injury were also evaluated. Treatment with 12b increased cell viability in SH-SY5Y cells pretreated with 250 MUM NMDA, with significant effects (P < 0.05) at concentrations between 0.5 and 5 MUM. These findings suggest that THAI can be used as a scaffold for developing new drug leads for the treatment of Alzheimer type neurodegeneration syndrome. PMID- 27688185 TI - K-Ras and its inhibitors towards personalized cancer treatment: Pharmacological and structural perspectives. AB - The discovery of genetic, genomic and clinical biomarkers have revolutionized the treatment option in the form of personalized medicine which allows to accurately predict a person's susceptibility/progression of disease, the patient's response to therapy, and maximize the therapeutic outcome in terms of low/no toxicity for a particular patient. Recently, the U.S. Food and Drug Administration has realized the contribution of pharmacogenomics in better healthcare and advocated the consideration of pharmacogenomic principles in making safer and more effective drug. Many anticancer drugs show reduced or no response in cancer patients with tumor specific gene mutations such as B-Raf and K-Ras. The high incidence of K-Ras mutation has been reported in pancreatic, colon, and lung carcinomas. The identification of K-Ras as a clinical biomarker and potential therapeutic target has attracted the scientific community to develop effective and precise anticancer drug. Inhibitors which block farnesylation of Ras have been developed or under clinical trial studies. Tipifarnib, approved by USFDA for the treatment of elderly acute leukemia is a Ras pathway inhibitor. Some peptidomimetics and bi-substrate inhibitors like FTI 276, FTI 277, B956, B1086, L731, L735, L739, L750, BMS-214662, L778123, and L778123 are under clinical trials. Recently mutant K-Ras has been considered as potential biomarker and target for precise cancer therapy. This review focuses primarily on the Ras/Raf/MEK/ERK signaling pathway including K-Ras mutation as therapeutic target, inhibitors and their structure activity relationships (SARs) for the design and development of anticancer agents. PMID- 27688186 TI - Design, synthesis and pharmacological evaluation of 4,5-diarylisoxazols bearing amino acid residues within the 3-amido motif as potent heat shock protein 90 (Hsp90) inhibitors. AB - A structure-based medicinal chemistry optimization was conducted on the clinical Hsp90 inhibitor diarylisoxazole 3. Several series of new compounds were designed and synthesized by incorporating diversified amino acid derivatives with various lengths to the 3-amido motif of the isoxazole scaffold. Compound 14j was identified to have high Hsp90 binding potency (14 nM) and antiproliferative activity against H3122 human lung cancer and BT-474 breast cancer cells. Treatment of 14j with H3122 cell led to degradation of client protein ALK, reduction of downstream phosphorylation of AKT and ERK, and up-regulation of Hsp70. Molecular docking suggested that the terminal valine moiety and the ethyleneglycol linker in compound 14j formed additional apolar and polar interaction network with a number of amino acid residues. PMID- 27688187 TI - Novel 2-arylazoimidazole derivatives as inhibitors of Trypanosoma cruzi proliferation: Synthesis and evaluation of their biological activity. AB - In this work, the synthesis of a series of 2-arylazoimidazole derivatives 6-20 has been achieved through the reaction of imidazole with aryldiazonium salts, followed by ultrasound-assisted alkylation. This approach has important advantages including higher yield, shorter reaction times and milder reaction conditions. The structures of the compounds obtained were determined by MS, IR; and 1H and 13C NMR. The anti-Trypanosoma cruzi activity of the 15 compounds obtained was evaluated. Two compounds with piperidino substituents in the carboxamide moiety proved to be effective inhibitors of epimastigote proliferation, obtaining inhibition values comparable to those achieved with the reference drug Benznidazole. Besides, these compounds displayed low cytotoxicity on mammalian cells. In vivo, both compounds protected mice against a challenge with a lethal Trypanosoma cruzi strain. These results allow us to propose 2 arylazoimidazoles as lead compounds for the design of novel drugs to treat Chagas' disease. PMID- 27688188 TI - Synthesis and antioxidant evaluation of desmethylxanthohumol analogs and their dimers. AB - Four ring-closed analogs of natural prenylated chalcone desmethylxanthohumol (1) and their dimers were synthesized from the commercially available 1-(2,4,6 trihydroxyphenyl)ethan-1-one in five and six linear steps, respectively. The structures of the eight new derivatives were confirmed using1H NMR, 13C NMR and HRMS. The antioxidant activity of the new chalcone derivatives were evaluated in a PC12 cell model of H2O2-induced oxidative damage. The SAR studies suggested that the catechol motif was essential for the antioxidant activity. Moreover, the dimers showed better antioxidant activity than their corresponding monomers did. Among them, compound 14d was the most potent and increased PC12 cell viability from 25% to 85%. Flow cytometric analysis showed that compound 14d, the most potent compound, decreased the apoptotic PC12 cell percentage and significantly reduced the LDH release and 8-OHdG generation but increased the GSH levels in H2O2-treated PC12 cells. Furthermore, compound 14d had a higher FRAP value than that of gallic acid. It also reduced the stable ABTS+ free radical with a lower EC50 than that of gallic acid. PMID- 27688189 TI - Synthesis and in vitro characterization of novel fluorinated derivatives of the translocator protein 18 kDa ligand CfO-DPA-714. AB - The translocator protein 18 kDa (TSPO) is today a validated target for a number of therapeutic applications, but also a well-recognized diagnostic/imaging biomarker for the evaluation of inflammatory related-disease state and progression, prompting the development of specific and dedicated TSPO ligands worldwide. For this purpose, pyrazolo[1,5-a]pyrimidine acetamides constitute a unique class of high affinity and selectivity TSPO ligands; it includes DPA-714, a fluorine-containing derivative that has also been labelled with the positron emitter fluorine-18, and is nowadays widely used as a Positron Emission Tomography imaging probe. Recently, to prevent defluorination issues encountered in vivo with this tracer, a first series of analogues was reported where the oxygen atom bridging the phenyl ring of the core structure and the fluorinated moiety was replaced with a more robust linkage. Among this new series, CfO-DPA 714 was discovered as a highly promising TSPO ligand. Herein, a novel series of fluorinated analogues of the latter molecule were synthesized and in vitro characterized, where the pharmacomodulation at the amide position of the molecule was explored. Thirteen compounds were thus prepared from a common key-ester intermediate (synthesized in 7 steps from 4-iodobenzoate - 11% overall yield) and a set of commercially available amines and obtained with moderate to good yields (23-81%) and high purities (>95%). With one exception, all derivatives displayed nanomolar to subnanomolar affinity for the TSPO and also high selectivity versus the CBR (Ki (CBR)/Ki (TSPO) > 103). Within this series, three compounds showed better Ki values (0.25, 0.26 and 0.30 nM) than that of DPA-714 (0.91 nM) and CfO DPA-714 (0.37 nM), and favorable lipophilicity for brain penetration (3.6 < logD7.4 < 4.4). Among these three compounds, the N-methyl-N-propyl amide analogue (9) exhibited similar metabolic stability when compared to CfO-DPA-714 in mouse, rat and human microsomes. Therefore, the latter compound stands out as a promising candidate for drug development or for use as a PET probe, once fluorine 18-labelled, for in vivo neuroinflammation imaging. PMID- 27688190 TI - Design, selective alkylation and X-ray crystal structure determination of dihydro indolyl-1,2,4-triazole-3-thione and its 3-benzylsulfanyl analogue as potent anticancer agents. AB - Three sets of substituted indolyl-triazoles were synthesized by the alkylation of 1,2-dihydro-5-(1H-indol-2-yl)-1,2,4-triazole-3-thione with different alkyl halides. The use of pyridine restricted the alkylation to sulfur. Whereas, upon using K2CO3, the alkylation exceeded sulfur to one of the remaining triazole nitrogens. The assignment of which nitrogen is alkylated besides sulfur is made for the first time using X-ray analysis of single crystals and 2D NMR which indicated that S-, 2-N-isomers will be preferably formed over the S-, 1-N isomers. The antiproliferative activity on HEPG-2 and MCF-7 cancer cell lines was tested. The results showed that compound 2a is the most active with an IC50 3.58 MUg/mL and 4.53 MUg/mL for HEPG-2 and MCF-7 respectively and compound 7 is the least active with an IC50 > 100 MUg/mL compared to the standard drug doxorubicin (IC50 4.0 MUg/mL). The interaction of the synthesized compounds with tyrosine kinases, namely, Akt, PI3, and EGFR was also studied using molecular docking simulation to predict their mode of action which will drive future work directions. PMID- 27688191 TI - Mechanistic and biological characteristics of different sugar conjugated 2-methyl malonatoplatinum(II) complexes as new tumor targeting agents. AB - Novel cis-2-methylmalonato(trans-R,R-cyclohexane-1,2-diamine)platinum(II) glycoconjugates derived from different sugar motifs, namely, glucose (Glu-Me-Pt), mannose (Man-Me-Pt) and galactose (Gal-Me-Pt) were designed and synthesized based on the third generation clinical drug oxaliplatin for potential glucose transporters (GLUTs) mediated tumor targeting. All platinum(II) glycoconjugates were characterized by 1H NMR, 13C NMR, IR, HRMS as well as 195Pt-NMR analysis. Despite their substantial improvement in water solubility, the conjugates exhibited comparable or better in vitro cytotoxicities than oxaliplatin determined in six different human cancer cell lines. Glu-Me-Pt has been shown to be more effective than cisplatin and oxaliplatin with improved therapeutic index in leukemia-bearing DBA/2 mice model. The potential GLUT transportability of the complexes was investigated using cell-based fluorescent competition assay and GLUT inhibitor mediated cell viability analysis in GLUT over-expressing HT29 cell line. Each sugar motif was found to be useful to enable the platinum(II) complexes as substrate for GLUT mediated cell uptake. In vitro DNA adduct formation analysis has been investigated for the first time for this class of compounds to reveal the intrinsic differences in antitumor activity between the malonatoplatinum(II) glycoconjugates and oxaliplatin. The intrinsic DNA reactivity of the platinum(II)-sugar conjugates was found as Gal-Me-Pt > Glu-Me Pt > Man-Me-Pt ~ oxaliplatin by kinetic study on the formation of platinum(II) adducts with guanosine-5'-monophosphate (5'-GMP). The results from this study demonstrate the usefulness of glucose, mannose and galactose as alternative sugar motif on glycoconjugation for GLUT mediated drug design and pharmaceutical R&D, and the obtained fundamental results also support the potential of the GLUT targeted platinum(II)-sugar conjugates as lead compounds for further pre-clinical evaluation. PMID- 27688192 TI - Quinolidene-rhodanine conjugates: Facile synthesis and biological evaluation. AB - A series of rhodanine incorporated quinoline derivatives were efficiently synthesized using reusable DBU acetate as ionic liquid and evaluated for their in vitro antitubercular activity against Mycobacterium tuberculosis H37Ra (MTB) (ATCC 25177) and Mycobacterium bovis BCG (ATCC 35743) both in active and dormant state. Compounds 3e, 3f, 3g, 3h and 3i exhibited very good antitubercular activity. The active compounds were studied for cytotoxicity against HUVEC, THP 1, macrophages, A549, PANC-1 and HeLa cell lines using modified MTT assay and were found to be noncytotoxic. Inactivity of all these compounds against Gram positive and Gram negative bacteria indicates their specificity towards the MTB. Further, the synthesized compounds have been screened for their in vitro antifungal activity. In addition, the molecular docking studies revealed the binding modes of these compounds in active site of Zmp1 enzyme, which in turn helped to establish a structural basis of inhibition of mycobacteria. The results of present study clearly indicate the identification of some novel, selective and specific inhibitors against MTB that can be explored further for potential antitubercular drug.

The synthesized compounds were evaluated for their in vitro anti proliferative activity against PANC 1, HeLa and MDA-MB-231. The compounds 8d, 8e, 8f, 8g, 8h and 8k exhibited considerable anti-proliferative activity with GI50 values ranging from 0.15 to 1.4 MUM. The structure and anti-proliferative activity relationship was further supported by in silico molecular docking study of the active compounds against tubulin protein.

AB - BACKGROUND: Effects on non-motor symptoms, mainly cognitive and psychiatric side effects, could influence the decision for either globus pallidus pars interna (GPi) or subthalamic nucleus (STN) deep brain stimulation (DBS) for patients with Parkinson's disease (PD). OBJECTIVE: 1) To compare cognitive and psychiatric outcomes 3 years after GPi DBS versus STN DBS, and 2) to report on occurrence of suicidal ideation, psychiatric diagnoses, social functioning, and marital satisfaction 3 years after DBS. METHODS: Patients were randomized to receive GPi DBS (n = 65) or STN DBS (n = 63). Standardized assessments were performed at baseline, 1 year, and 3 years. We used linear mixed model analyses to investigate between-group differences on the Mattis Dementia Rating Scale (MDRS), neuropsychological tests, and psychiatric questionnaires 3 years after DBS. RESULTS: Eighty-seven patients (68%) completed at least one neuropsychological test after 3 years. No significant between-group differences were found on the MDRS (p = 0.61), neuropsychological tests (p-values between 0.17 and 0.87), and psychiatric questionnaires (p-values between 0.23 and 0.88) 3 years after DBS. The Mini International Neuropsychiatric Interview did not indicate a substantial number of psychiatric diagnoses after 3 years. Social functioning and marital satisfaction were comparable in both groups. CONCLUSIONS: Three years after GPi DBS and STN DBS no pronounced between-group differences on measures of cognitive and psychiatric functioning could be demonstrated. Overall, cognitive and psychiatric outcome 3 years after DBS do not provide a clear direction for clinicians when considering which of these two surgical targets to choose. PMID- 27688201 TI - Do tumor necrosis factor inhibitors increase cancer risk in patients with chronic immune-mediated inflammatory disorders? AB - Inhibition of tumor necrosis factor (TNF) activity has profoundly changed the management of several immune-mediated inflammatory diseases with great benefit for patients. The application of TNF inhibitors (TNFi), however, also brings a new concern, malignancy. We performed a systemic review to collect the studies reporting cancer incidences and risks in TNFi users regardless of indications. TNFi were most frequently used in treating patients with rheumatoid arthritis (RA) and inflammatory bowel diseases (IBD). In RA patients without prior cancer history, the incidences of malignancies ranged from the lowest rate 0 per 1000 person-years in etanercept users regarding lymphoma to the highest rate 35.62 per 1000 person-years in adalimumab users on non-melanoma skin cancer (NMSC), while in those patients with prior cancer history, the recurrent incidences of malignancies ranged from the lowest rate 5.05 per 1000 person-years regarding melanoma to the highest rate 63.20 per 1000 person-years on basal cell carcinoma (BCC) in TNFi users. In IBD patients, incidences ranged from 0 per 1000 person years in TNFi users on lymphoma to 34.0 per 1000 person-years in infliximab users on overall cancer. However, these incidence rates of overall cancer, lymphoma and melanoma were not higher in comparison with those patients who were not treated with TNFi. Compared to general population, incidences of lymphoma were elevated in RA patients and rates of NMSC were higher in patients with psoriasis, RA and IBD. In conclusion, cancer incidences vary across different studies, indications, cancer types and studies with different individual TNFi. Treatment with TNFi is not associated with increased malignant risks of overall cancer, lymphoma or melanoma. Results of NMSC risk were inconsistent among studies. A latest prospective registry study demonstrated a small increased risk of squamous cell cancer in RA patients treated with TNFi (one additional case for every 1600years of treatment experience). Further prospective studies are needed to verify whether TNFi users have higher NMSC risk than non-TNFi users.

AB - Photic stimulation of rods, cones and intrinsically photosensitive melanopsin containing retinal ganglion cells (ipRGCs) mediates non-visual light responses, including entrainment of circadian rhythms and pupillary light reflex. Unlike visual responses to photic stimulation, the cerebral correlates of non-visual light responses in humans remains elusive. In this study, we used functional magnetic resonance imaging (fMRI) in 14 healthy young participants, to localize cerebral regions which are differentially activated by metameric light that gave rise to different levels of melanopic excitation. Mean blood oxygen-level dependent (BOLD) responses disclosed bilateral activation of the frontal eye fields during exposure to light geared towards melanopsin. Furthermore, multivariate pattern analyses showed distinct bilateral pattern activity in the inferior temporal gyri and the caudate nuclei. Taken together, our findings suggest that melanopsin-based photoreception activates a cerebral network including frontal regions, classically involved in attention and ocular motor responses. PMID- 27688203 TI - Individualized parcellation of the subthalamic nucleus in patients with Parkinson's disease with 7T MRI. AB - Deep brain stimulation of the subthalamic nucleus (STN) is a widely performed surgical treatment for patients with Parkinson's disease. The goal of the surgery is to place an electrode centered in the motor region of the STN while lowering the effects of electrical stimulation on the non-motor regions. However, distinguishing the motor region from the neighboring associative and limbic areas in individual patients using imaging modalities was until recently difficult to obtain in vivo. Here, using ultra-high field MR imaging, we have performed a dissection of the subdivisions of the STN of individual Parkinson's disease patients. We have acquired 7T diffusion-weighted images of seventeen patients with Parkinson's disease scheduled for deep brain stimulation surgery. Using a structural connectivity-based parcellation protocol, the STN's connections to the motor, limbic, and associative cortical areas were used to map the individual subdivisions of the nucleus. A reproducible patient-specific parcellation of the STN into a posterolateral motor and gradually overlapping central associative area was found in all STNs, taking up on average 55.3% and 55.6% of the total nucleus volume. The limbic area was found in the anteromedial part of the nucleus. Our results suggest that 7T MR imaging may facilitate individualized and highly specific planning of deep brain stimulation surgery of the STN.

AB - Dyslexia is a literacy disorder affecting the efficient acquisition of reading and writing skills. The disorder is neurobiological in origin. Due to its developmental nature, longitudinal studies of dyslexia are of essence. They are, however, relatively scarce. The present study took a longitudinal approach to cortical connectivity of brain imaging data in reading tasks in children with dyslexia and children with typical reading development. The participants were followed with repeated measurements through Pre-literacy (6 years old), Emergent Literacy (8 years old) and Literacy (12 years old) stages, using Dynamic Causal Modelling (DCM) when analysing functional magnetic resonance imaging (fMRI) data. Even though there are a few longitudinal studies on effective connectivity in typical reading, to our knowledge, no studies have previously investigated these issues in relation to dyslexia. We set up a model of a brain reading network involving five cortical regions (inferior frontal gyrus, precentral gyrus, superior temporal gyrus, inferior parietal lobule, and occipito-temporal cortex). Using DCM, connectivity measures were calculated for each connection in the model. These measures were further analysed using factorial ANOVA. The results showed that the difference between groups centred on connections going to and from the inferior frontal gyrus (two connections) and the occipito-temporal cortex (three connections). For all five connections, the typical group showed stable or decreasing connectivity measures. The dyslexia group, on the other hand, showed a marked up-regulation (occipito-temporal connections) or down regulation (inferior frontal gyrus connections) from 6 years to 8 years, followed by normalization from 8 years to 12 years. We interpret this as a delay in the dyslexia group in developing into the Pre-literacy and Emergent literacy stages. This delay could possibly be detrimental to literacy development. By age 12, there was no statistically significant difference in connectivity between the groups, but differences in literacy skills were still present, and were in fact larger than when measured at younger ages.

AB - BACKGROUND AND AIMS: The role of endoscopic submucosal dissection (ESD) in Barrett's early neoplasia is not well defined, with most studies originating from Asia and Europe. We aimed to assess the efficacy, safety, and results of ESD in Barrett's esophagus (BE) with high-grade dysplasia (HGD) and early adenocarcinoma (EAC) across centers in the United States. METHODS: Multicenter retrospective analysis on 46 patients with BE who underwent ESD for BE-HGD or EAC, or both, between January 2010 and April 2015. The primary endpoint was the rate of en bloc resection. Secondary aims included rate of R0 (complete) and curative resection, a comparison of pre- and post-ESD histology, procedure-related adverse events, and rate of remission at follow-up. RESULTS: Median age was 69 years (range, 42 82 years). The median resected specimen size was 45 mm (range, 13-125 mm). En bloc and curative resection rates were 96% (44/46) and 70% (32/46), respectively. Most lesions (11/20; 55%) diagnosed as BE-HGD on biopsy were upstaged to intramucosal or invasive EAC on post-ESD histopathology. There were 4 early (<48 hours) adverse events (3 bleeding and 1 perforation), and all were treated endoscopically. Seven patients (15%) developed esophageal strictures that were managed endoscopically. Complete remission of BE neoplasia was found in 100% (32/32) of patients with curative resection at median follow-up of 11 months (range, 2-25 months). CONCLUSIONS: This is the largest multicenter series of ESD for early neoplastic BE from the United States. ESD appears to be safe and effective, with high en bloc and curative resection rates in the treatment of early BE neoplasia. PMID- 27688206 TI - Arbuscular Mycorrhizal Symbiosis Requires a Phosphate Transceptor in the Gigaspora margarita Fungal Symbiont. AB - The majority of terrestrial vascular plants are capable of forming mutualistic associations with obligate biotrophic arbuscular mycorrhizal (AM) fungi from the phylum Glomeromycota. This mutualistic symbiosis provides carbohydrates to the fungus, and reciprocally improves plant phosphate uptake. AM fungal transporters can acquire phosphate from the soil through the hyphal networks. Nevertheless, the precise functions of AM fungal phosphate transporters, and whether they act as sensors or as nutrient transporters, in fungal signal transduction remain unclear. Here, we report a high-affinity phosphate transporter GigmPT from Gigaspora margarita that is required for AM symbiosis. Host-induced gene silencing of GigmPT hampers the development of G. margarita during AM symbiosis. Most importantly, GigmPT functions as a phosphate transceptor in G. margarita regarding the activation of the phosphate signaling pathway as well as the protein kinase A signaling cascade. Using the substituted-cysteine accessibility method, we identified residues A146 (in transmembrane domain [TMD] IV) and Val357 (in TMD VIII) of GigmPT, both of which are critical for phosphate signaling and transport in yeast during growth induction. Collectively, our results provide significant insights into the molecular functions of a phosphate transceptor from the AM fungus G. margarita. PMID- 27688208 TI - Resection of highly language-eloquent brain lesions based purely on rTMS language mapping without awake surgery. AB - BACKGROUND: The resection of left-sided perisylvian brain lesions harbours the risk of postoperative language impairment. Therefore the individual patient's language distribution is investigated by intraoperative direct cortical stimulation (DCS) during awake surgery. Yet, not all patients qualify for awake surgery. Non-invasive language mapping by repetitive navigated transcranial magnetic stimulation (rTMS) has frequently shown a high correlation in comparison with the results of DCS language mapping in terms of language-negative brain regions. The present study analyses the extent of resection (EOR) and functional outcome of patients who underwent left-sided perisylvian resection of brain lesions based purely on rTMS language mapping. METHODS: Four patients with left sided perisylvian brain lesions (two gliomas WHO III, one glioblastoma, one cavernous angioma) underwent rTMS language mapping prior to surgery. Data from rTMS language mapping and rTMS-based diffusion tensor imaging fibre tracking (DTI FT) were transferred to the intraoperative neuronavigation system. Preoperatively, 5 days after surgery (POD5), and 3 months after surgery (POM3) clinical follow-up examinations were performed. RESULTS: No patient suffered from a new surgery-related aphasia at POM3. Three patients underwent complete resection immediately, while one patient required a second rTMS-based resection some days later to achieve the final, complete resection. CONCLUSIONS: The present study shows for the first time the feasibility of successfully resecting language-eloquent brain lesions based purely on the results of negative language maps provided by rTMS language mapping and rTMS-based DTI-FT. In very select cases, this technique can provide a rescue strategy with an optimal functional outcome and EOR when awake surgery is not feasible. PMID- 27688209 TI - D-Xylose fermentation, xylitol production and xylanase activities by seven new species of Sugiyamaella. AB - Sixteen yeast isolates identified as belonging to the genus Sugiyamaella were studied in relation to D-xylose fermentation, xylitol production, and xylanase activities. The yeasts were recovered from rotting wood and sugarcane bagasse samples in different Brazilian regions. Sequence analyses of the internal transcribed spacer (ITS) region and the D1/D2 domains of large subunit rRNA gene showed that these isolates belong to seven new species. The species are described here as Sugiyamaella ayubii f.a., sp. nov. (UFMG-CM-Y607T = CBS 14108T), Sugiyamaella bahiana f.a., sp. nov. (UFMG-CM-Y304T = CBS 13474T), Sugiyamaella bonitensis f.a., sp. nov. (UFMG-CM-Y608T = CBS 14270T), Sugiyamaella carassensis f.a., sp. nov. (UFMG-CM-Y606T = CBS 14107T), Sugiyamaella ligni f.a., sp. nov. (UFMG-CM-Y295T = CBS 13482T), Sugiyamaella valenteae f.a., sp. nov. (UFMG-CM Y609T = CBS 14109T) and Sugiyamaella xylolytica f.a., sp. nov. (UFMG-CM-Y348T = CBS 13493T). Strains of the described species S. boreocaroliniensis, S. lignohabitans, S. novakii and S. xylanicola, isolated from rotting wood of Brazilian ecosystems, were also compared for traits relevant to xylose metabolism. S. valenteae sp. nov., S. xylolytica sp. nov., S. bahiana sp. nov., S. bonitensis sp. nov., S. boreocarolinensis, S. lignohabitans and S. xylanicola were able to ferment D-xylose to ethanol. Xylitol production was observed for all Sugiyamaella species studied, except for S. ayubii sp. nov. All species studied showed xylanolytic activity, with S. xylanicola, S. lignohabitans and S. valenteae sp. nov. having the highest values. Our results suggest these Sugiyamaella species have good potential for biotechnological applications. PMID- 27688210 TI - Microbacterium rhizosphaerae sp. nov., isolated from a Ginseng field, South Korea. AB - A novel Gram-stain positive, aerobic, short rod-shaped, non-motile bacterium, designated strain CHO1T, was isolated from rhizosphere soil from a ginseng agriculture field. Strain CHO1T was observed to form yellow colonies on R2A agar medium. The cell wall peptidoglycan was found to contain alanine, glycine, glutamic acid, D-ornithine and serine. The cell wall sugars were identified as galactose, mannose, rhamnose and ribose. Strain CHO1T was found to contain MK-11, MK-12, MK-13 as the predominant menaquinones and anteiso-C15:0, iso-C16:0, and anteiso-C17:0 as the major fatty acids. Diphosphatidylglycerol, phosphatidylglycerol, phosphoglycolipid, an unidentified phospholipid and three unidentified glycolipids were found to be present in strain CHO1T. Based on 16S rRNA gene sequence analysis, strain CHO1T was found to be closely related to Microbacterium mangrovi DSM 28240T (97.81 % similarity), Microbacterium immunditiarum JCM 14034T (97.45 %), Microbacterium oryzae JCM 16837T (97.33 %) and Microbacterium ulmi KCTC 19363T (97.10 %) and to other species of the genus Microbacterium. The DNA G+C content of CHO1T was determined to be 70.1 mol %. The DNA-DNA hybridization values of CHO1T with M. mangrovi DSM 28240T, M. immunditiarum JCM 14034T, M. oryzae JCM 16837T and M. ulmi KCTC 19363T were 46.7 +/- 2, 32.4 +/- 2, 32.0 +/- 2 and 29.2 +/- 2 %, respectively. On the basis of genotypic, phenotypic and phylogenetic properties, it is concluded that strain CHO1T represents a novel species within the genus Microbacterium, for which the name Microbacterium rhizosphaerae sp. nov. is proposed. The type strain of M. rhizosphaerae is CHO1T (= KEMB 7306-513T = JCM 31396T). PMID- 27688211 TI - Reclassification of Halomonas caseinilytica Wu et al. 2008 as a later synonym of Halomonas sinaiensis-Comments on the proposal by Hwang et al., Antonie van Leeuwenhoek 109:1345-1352, 2016. AB - Hwang et al. (Antonie van Leeuwenhoek 109:1345-1352, 2016) proposed the reclassification of Halomonas caseinilytica (Wu et al. 2008) as a later synonym of Halomonas sinaiensis, based on the publication of the latter name in 2007 by Romano et al. However, the name H. sinaiensis was validly published only in 2011. Therefore the proposal by Hwang et al. is not appropriate; instead, the name H. sinaiensis can be proposed as a later synonym of H. casinilytica. PMID- 27688207 TI - Applications of Extracellular RNAs in Oncology. AB - Extracellular RNAs consist of coding and non-coding transcripts released from all cell types, which are involved in multiple cellular processes, predominantly through regulation of gene expression. Recent advances have helped us better understand the functions of these molecules, particularly microRNAs (miRNAs). Numerous pre-clinical and human studies have demonstrated that miRNAs are dysregulated in cancer and contribute to tumorigenesis and metastasis. miRNA profiling has extensively been evaluated as a non-invasive method for cancer diagnosis, prognostication, and assessment of response to cancer therapies. Broader applications for miRNAs in these settings are currently under active development. Investigators have also moved miRNAs into the realm of cancer therapy. miRNA antagonists targeting miRNAs that silence tumor suppressor genes have shown promising pre-clinical activity. Alternatively, miRNA mimics that silence oncogenes are also under active investigation. These miRNA-based cancer therapies are in early development, but represent novel strategies for clinical management of human cancer. PMID- 27688213 TI - Mucosal Perforation During Laparoscopic Heller Myotomy Has No Influence on Final Treatment Outcome. AB - BACKGROUND: The aims of the study were (a) to examine the final outcome in patients experiencing accidental mucosal perforation during laparoscopic Heller myotomy with Dor fundoplication (LHD) and (b) to evaluate whether perforation episodes might influence the way in which surgeons subsequently approached the LHD procedure. METHODS: We studied all consecutive patients that underwent LHD between 1992 and 2015. Patients were divided into two main groups: those who experienced an intraoperative mucosal perforation (group P) and those whose LHD was uneventful (group NP). Two additional groups were compared: group A, which consisted of patients operated by a given surgeon immediately before a perforation episode occurred, and group B, which included those operated immediately afterwards. RESULTS: Eight hundred seventy-five patients underwent LHD; a mucosal perforation was detected in 25 patients (2.9 %), which was found unrelated to patients' symptom's score and age, radiological stage, manometric pattern, or the surgeon's experience. The median postoperative symptom score was similar for the two groups as the failure rate: 92 failures in group NP (10.8 %) and 4 in group P (16 %) (p = 0.34); moreover, symptoms recurred in 2 patients of group A (10 %) and 3 patients of group B (15 %) (p = 0.9). CONCLUSIONS: Accidental perforation during LHD is infrequent and impossible to predict on the grounds of preoperative therapy or the surgeon's personal experience. Despite a longer surgical procedure and hospital stay, the outcome of LHD is much the same as for patients undergoing uneventful myotomy. A recent mucosal perforation does not influence the surgeon's subsequent performance. PMID- 27688214 TI - The Clinical Utility of Over-the-Scope Clip for the Treatment of Gastrointestinal Defects. AB - BACKGROUND: The over-the-scope clip (OTSC) is a novel endoscopic tool that enables non-surgical management of gastrointestinal (GI) defects. The aim of this study was to report our experience with OTSC for patients with GI defects. METHODS: A prospectively maintained IRB-approved institutional database was queried for all patients treated with OTSC from 2012 to 2015. Primary outcome was the clinical success of the OTSC for the individual indication. Secondary outcome was the number of additional procedures needed following OTSC. RESULTS: Fifty-one patients were treated with OTSC: upper GI (UGI) 30 and lower GI (LGI) 21. GI leak (n = 24; UGI = 12, LGI = 12) and fistulae (n = 17; UGI = 8, LGI = 9) were the most common indications. Overall success rate for the treatment of leaks was 59 % [UGI 66 % vs. LGI 33 % (p = 0.1)]. A lower success rate (35 %) was noted for fistulae [UGI 62 % vs. LGI 0 % (p = 0.001)]. Success rates for UGI perforation, bleeding, and stent anchoring indications were 75, 75, and 50 %, respectively. Additional endoscopic or surgical interventions following OTSC were indicated in 68.6 % of the patients. CONCLUSIONS: OTSC appears to have additional value in treating UGI defects. However, lower success rates for LGI defects were noted, specifically for fistulae. Most patients require an additional endoscopic or surgical procedure after one OTSC application. PMID- 27688212 TI - Patient Adherence and Experience with Extended Use of Prophylactic Low-Molecular Weight Heparin Following Pancreas and Liver Resection. AB - BACKGROUND: Guidelines recommend 28 days venous thromboembolism (VTE) prophylaxis with low-molecular-weight heparin (LMWH) following major abdominal surgery for cancer. Overall adherence with these recommendations is poor, but little is known about feasibility and tolerability from a patient perspective. METHODS: An institution-wide policy for routine administration of 28 days of post-operative LMWH following major hepatic or pancreatic resection for cancer was implemented in April 2013. Patients having surgery from July 2013 to June 2015 were approached to participate in an interview examining adherence and experience with extended duration LMWH. RESULTS: There were 100 patients included, with 81.4 % reporting perfect adherence with the regimen. The most frequent reasons for non adherence were that a healthcare provider stopped the regimen or because of poor experience with injections. Most patients were able to correctly recall the reason for being prescribed LMWH (82.6 %), and 78.4 % of patients performed all injections themselves. Over half the patients (55.7 %) did not find the injections bothersome. CONCLUSION: Patients reported high adherence and a manageable experience with post-operative extended-duration LMWH in an ambulatory setting following liver or pancreas resection. These findings suggest that patient adherence is not a major contributor to poor compliance with VTE prophylaxis guidelines. PMID- 27688218 TI - Nonlinear statistical data assimilation for HVC[Formula: see text] neurons in the avian song system. AB - With the goal of building a model of the HVC nucleus in the avian song system, we discuss in detail a model of HVC[Formula: see text] projection neurons comprised of a somatic compartment with fast Na[Formula: see text] and K[Formula: see text] currents and a dendritic compartment with slower Ca[Formula: see text] dynamics. We show this model qualitatively exhibits many observed electrophysiological behaviors. We then show in numerical procedures how one can design and analyze feasible laboratory experiments that allow the estimation of all of the many parameters and unmeasured dynamical variables, given observations of the somatic voltage [Formula: see text] alone. A key to this procedure is to initially estimate the slow dynamics associated with Ca, blocking the fast Na and K variations, and then with the Ca parameters fixed estimate the fast Na and K dynamics. This separation of time scales provides a numerically robust method for completing the full neuron model, and the efficacy of the method is tested by prediction when observations are complete. The simulation provides a framework for the slice preparation experiments and illustrates the use of data assimilation methods for the design of those experiments. PMID- 27688220 TI - Effects of Kinesio taping compared to arterio-venous Impulse SystemTM on limb swelling and skin temperature after total knee arthroplasty. AB - PURPOSE: It is an established fact that post-operative (p.o.) soft-tissue swelling and lymphoedema after total knee arthroplasty (TKA) have a major influence on the p.o. early functional outcome. Kinesio taping has a proven clinical effect in increasing lymph drainage. Despite the decades of experience gained and the assumed positive effects, hardly any investigations have been conducted to date on the influence of Kinesio taping on the p.o. healing process after TKA. The objective of the present study was to test the hypothesis that Kinesio taping used as a lymph application leads to a reduction of p.o. soft tissue swelling. As a secondary objective, it was to be tested whether there is an effect on skin temperature as a surrogate parameter for dermal micro circulation. METHODS: In this prospective study with a historical control (A-V Impulse SystemTM group), 42 subjects were included and treated with Kinesio taping after implantation of a TKA. The patients of the study group were treated immediately p.o. with Kinesio(r) Tex GoldTM fan cut tape as a lymph application with a common base. A thermographic temperature determination of the knee joint operated on was performed on each patient in the supine position every day from the first to the seventh p.o. day. The leg circumference was documented daily at eight specified measuring points on both lower limbs. As a statistical analytical approach, the so-called principal component analysis was used. An analysis of variance was performed. The significance level was set at p < 0.001. RESULTS: The course of soft-tissue swelling of the study group did not differ from that of the control group at any point in time. For the temperature course of the medial wound aspect, no difference was seen between the Kinesio taping study group and the A-V Impulse SystemTM group. In contrast, the temperature course of the lateral wound aspect showed a reproducibly higher temperature in the Kinesio tape group than in the control group (0.6 degrees C (0.5-0.8), p < 0.001). CONCLUSION: The hypothesis of the study that Kinesio taping as a lymph application induces a reduction of soft-tissue swelling after TKA must be rejected on the basis of the present data. Solely the temperature of the lateral wound aspect was higher in the Kinesio taping group than in the control group, so that an increased blood circulation can be assumed here. Considering that the actively working A-V Impulse SystemTM used in the control group also increases local blood circulation, the effect of the passive Kinesio tape is surprising. However, this was not reflected in a quicker wound healing, as the day of last wound secretion was the same in both groups. Kinesio taping as a lymph application represents an equivalent alternative to the A-V Impulse SystemTM for therapy after total knee arthroplasty with regard to soft-tissue swelling and wound healing. PMID- 27688221 TI - Examining Smoking Cessation in a Community-Based Versus Clinic-Based Intervention Using Community-Based Participatory Research. AB - Tobacco use remains a major public health problem in the U.S. disproportionately affecting underserved communities. The Communities Engaged and Advocating for a Smoke-free Environment (CEASE) initiative is an intervention to address the problem using a community-based participatory research (CBPR) approach. This study compares quit rates in a peer-led community-based intervention with those achieved in a clinical setting. The intervention consisted of three Phases. Phase I (n = 404) was a clinic-based trial comparing two types of counseling. Phase II (n = 398) and Phase III (n = 163) interventions were conducted in community venues by trained Peer Motivators. Quit rates at 12-week follow-up increased from 9.4 % in Phase I (clinic-based) to an average of 23.7 % in Phases II and III combined (community-based). The main predictor of smoking cessation was delivery of services in community settings (OR 2.6, 95 % CI 1.7-4.2) while controlling for possible confounders. A community-based approach can significantly guide and improve effectiveness and acceptability of smoking cessation services designed for low-income urban populations. In addition, CBPR can result in better recruitment and retention of the participants. PMID- 27688222 TI - Antibiotics: The good, the bad, and the ugly. PMID- 27688219 TI - Strengthening Health Systems While Responding to a Health Crisis: Lessons Learned by a Nongovernmental Organization During the Ebola Virus Disease Epidemic in Sierra Leone. AB - An epidemic of Ebola virus disease (EVD) beginning in 2013 has claimed an estimated 11 310 lives in West Africa. As the EVD epidemic subsides, it is important for all who participated in the emergency Ebola response to reflect on strengths and weaknesses of the response. Such reflections should take into account perspectives not usually included in peer-reviewed publications and after action reports, including those from the public sector, nongovernmental organizations (NGOs), survivors of Ebola, and Ebola-affected households and communities. In this article, we first describe how the international NGO Partners In Health (PIH) partnered with the Government of Sierra Leone and Wellbody Alliance (a local NGO) to respond to the EVD epidemic in 4 of the country's most Ebola-affected districts. We then describe how, in the aftermath of the epidemic, PIH is partnering with the public sector to strengthen the health system and resume delivery of regular health services. PIH's experience in Sierra Leone is one of multiple partnerships with different stakeholders. It is also one of rapid deployment of expatriate clinicians and logistics personnel in health facilities largely deprived of health professionals, medical supplies, and physical infrastructure required to deliver health services effectively and safely. Lessons learned by PIH and its partners in Sierra Leone can contribute to the ongoing discussion within the international community on how to ensure emergency preparedness and build resilient health systems in settings without either.

AB - Polyaniline (PANi)/graphene nanocomposites have attracted tremendous interest because of their great potential in electrochemical energy storage applications, especially supercapacitors. We herein focus on the composite synthesis, device fabrication and particularly various techniques for the improvement of electrochemical performance. It is imperative to take close control of the interface in these nanostructured composites, which thus would lead to the desired synergistic effects and cyclic stability with the efficient diffusion of electrolyte ions and electrons. Challenges and perspectives are discussed for the development of highly efficient PANi/graphene electrodes for supercapacitors. PMID- 27688235 TI - Location of In-Hospital Cardiac Arrest in the United States-Variability in Event Rate and Outcomes. AB - BACKGROUND: In-hospital cardiac arrest (IHCA) is a major public health problem with significant mortality. A better understanding of where IHCA occurs in hospitals (intensive care unit [ICU] versus monitored ward [telemetry] versus unmonitored ward) could inform strategies for reducing preventable deaths. METHODS AND RESULTS: This is a retrospective study of adult IHCA events in the Get with the Guidelines-Resuscitation database from January 2003 to September 2010. Unadjusted analyses were used to characterize patient, arrest, and hospital level characteristics by hospital location of arrest (ICU versus inpatient ward). IHCA event rates and outcomes were plotted over time by arrest location. Among 85 201 IHCA events at 445 hospitals, 59% (50 514) occurred in the ICU compared to 41% (34 687) on the inpatient wards. Compared to ward patients, ICU patients were younger (64+/-16 years versus 69+/-14; P<0.001) and more likely to have a presenting rhythm of ventricular tachycardia/ventricular fibrillation (21% versus 17%; P<0.001). In the ICU, mean event rate/1000 bed-days was 0.337 (+/-0.215) compared with 0.109 (+/-0.079) for telemetry wards and 0.134 (+/-0.098) for unmonitored wards. Of patients with an arrest in the ICU, the adjusted mean survival to discharge was 0.140 (0.037) compared with the unmonitored wards 0.106 (0.037) and telemetry wards 0.193 (0.074). More IHCA events occurred in the ICU compared to the inpatient wards and there was a slight increase in events/1000 patient bed-days in both locations. CONCLUSIONS: Survival rates vary based on location of IHCA. Optimizing patient assignment to unmonitored wards versus telemetry wards may contribute to improved survival after IHCA.

PMID- 27688236 TI - Cardiac Remote Ischemic Preconditioning Prior to Elective Vascular Surgery (CRIPES): A Prospective, Randomized, Sham-Controlled Phase II Clinical Trial. AB - BACKGROUND: Remote ischemic preconditioning (RIPC) has been shown to reduce infarct size in animal models. We hypothesized that RIPC before an elective vascular operation would reduce the incidence and amount of a postoperative rise of the cardiac troponin level. METHODS AND RESULTS: Cardiac Remote Ischemic Preconditioning Prior to Elective Vascular Surgery (CRIPES) was a prospective, randomized, sham-controlled phase 2 trial using RIPC before elective vascular procedures. The RIPC protocol consisted of 3 cycles of 5-minute forearm ischemia followed by 5 minutes of reperfusion. The primary endpoint was the proportion of subjects with a detectable increase in cardiac troponin I (cTnI) and the distribution of such increases. From June 2011 to September 2015, 201 male patients (69+/-7, years) were randomized to either RIPC (n=100) or a sham procedure (n=101). Indications for vascular surgery included an expanding abdominal aortic aneurysm (n=115), occlusive peripheral arterial disease of the lower extremities (n=37), or internal carotid artery stenosis (n=49). Of the 201 patients, 47 (23.5%) had an increase in cTnI above the upper reference limit within 72 hours of the vascular operation, with no statistically significant difference between those patients assigned to RIPC (n=22; 22.2%) versus sham procedure (n=25; 24.7%; P=0.67). Among the cohort with increased cTnI, the median peak values (interquartile range) in the RIPC and control group were 0.048 (0.004 0.174) and 0.017 (0.003-0.105), respectively (P=0.54). CONCLUSIONS: In this randomized, controlled trial of men with increased perioperative cardiac risks, elevation in cardiac troponins was common following vascular surgery, but was not reduced by a strategy of RIPC.

PMID- 27688238 TI - Sex Differences and Survival in Adults With Bicuspid Aortic Valves: Verification in 3 Contemporary Echocardiographic Cohorts. AB - BACKGROUND: Sex-related differences in morbidity and survival in bicuspid aortic valve (BAV) adults are fundamentally unknown. Contemporary studies portend excellent survival for BAV patients identified at early echocardiographic clinical stages. Whether BAV adults incur a survival disadvantage throughout subsequent echocardiographic-clinical stages remains undetermined. METHODS AND RESULTS: Analysis was done of 3 different cohorts of consecutive patients with echocardiographic diagnosis of BAV identified retrospectively: (1) a community cohort of 416 patients with first BAV diagnosis (age 35+/-21 years, follow-up 16+/-7 years), (2) a tertiary clinical referral cohort of 2824 BAV adults (age 51+/-16 years, follow-up 9+/-6 years), and (3) a surgical referral cohort of 2242 BAV adults referred for aortic valve replacement (AVR) (age 62+/-14 years, follow up 6+/-5 years). For the community cohort, 20-year risks of aortic regurgitation (AR), AVR, and infective endocarditis were higher in men (all P<=0.04); for a total BAV-related morbidity risk of 52+/-4% vs 35+/-6% in women (P=0.01). The cohort's 25-year survival was identical to that in the general population (P=0.98). AR independently predicted mortality in women (P=0.001). Baseline AR was more common in men (P<=0.02) in the tertiary cohort, with 20-year survival lower than that in the general population (P<0.0001); age-adjusted relative death risk was 1.16 (95% confidence interval [CI] 1.05-1.29) for men versus 1.67 (95% CI 1.38-2.03) for women (P=0.001). AR independently predicted mortality in women (P=0.01). Baseline AR and infective endocarditis were higher in men (both <=0.001) for the surgical referral cohort, with 15-year survival lower than that in the general population (P<0.0001); age-adjusted relative death risk was 1.34 (95% CI 1.22-1.47) for men versus 1.63 (95% CI 1.40-1.89) for women (P=0.026). AR and NYHA class independently predicted mortality in women (both P<=0.04). CONCLUSIONS: Within evolving echocardiographic-clinical stages, the long-term survival of adults with BAV is not benign, as both men and women incur excess mortality. Although BAV-related morbidity is higher in men in the community, and AR and infective endocarditis are more prevalent in men, women exhibit a significantly higher relative risk of death in tertiary and surgical referral cohorts, which is independently associated with AR. PMID- 27688240 TI - How strong is the association between IPF and lung cancer? An answer from airway's DNA. AB - Idiopathic pulmonary fibrosis is a chronic progressive disease of lung interstitium of unknown etiology with poor prognosis. In patients with IPF, the incidence of lung cancer is much higher than that in the general population. The identification of noninvasive biomarkers for early diagnosis of IPF is of great relevance in consideration of the management of these patients. Among the noninvasive omic markers, an increasing interest has been directed toward the study of genetic alterations of microsatellites (MAs) in exhaled breath condensate (EBC). The aim of this preliminary study was to investigate the MAs, located in chromosomal regions 8p21.3-q11.1 and 17q11.2-q21, that harbor tumor suppressor genes, in EBC and in the paired whole blood (WB) of IPF patients. Eleven IPF patients were compared with 10 healthy control subjects. All subjects underwent collection of the EBC and WB. The EBC was collected using a condenser. Four microsatellite markers (THRA1, D17S579, D17S250 and D8S137) were used for the analysis of MAs. The EBC-DNA and WB-DNA were amplified by PCR; PCR products were analyzed using the ABI Prism 310 DNA. Microsatellite alterations were found in 58.82 % of EBC-DNA and 12.50 % of WB-DNA in patients with IPF (p < 0.01). None of the healthy subjects exhibited MAs in the studied markers. Our findings suggest that these genetic alterations, studied in EBC, may play an important role in the complex genetic basis of IPF. Since these MAs are frequently detected in cancer, they might explain the higher relative risk of tumorigenesis in this disease. PMID- 27688241 TI - Expression of Ezrin and Estrogen Receptors During Cervical Carcinogenesis. AB - RATIONALE: Development of cervical squamous carcinoma (CXCA) is accompanied by changes in estrogen receptors (ERs, ERalpha and ERbeta) and ezrin expression; however, reports have been conflicting. Using histologically documented staging of cervical biopsies, we determined ezrin and ER relationships during CXCA development. METHODS: Immunoreactive (ir) ezrin, ir-ERalpha, and ir-ERbeta were studied in normal epithelium, carcinoma in situ/cervical intraepithelial neoplasia (CIN) 1 to 3, and local invasion or metastatic CXCA. Results were compared using H scoring. Cultures of Caski metastatic CXCA cells were treated with estradiol and/or tamoxifen and studied for ER-driven ir-ezrin and the morphologic response. RESULTS: Koilocytosis was present and indicated viral presence. The ezrin H score increased from CIN1 to CIN3, reaching significant differences from normal by CIN3 ( P = .004) and 2* normal in metastatic CXCA. Estrogen receptor alpha and ERbeta H scores fell, reaching significance by CIN3 (ERalpha, P = .0001; ERbeta, P = .024). During estradiol treatment, ezrin in Caski cells increased and localized to the periphery, in ruffles and processes. The selective ER modulator tamoxifen blocked the estradiol-induced changes. CONCLUSIONS: During cervical carcinogenesis, the usual relationship between estrogen and ezrin induction is abridged. This is consistent with the effects of human papilloma virus viral proteins such as E6 and E7 that upregulate SIX1, a protein that induces ezrin. Cervical carcinogenesis is progressive but arrests at the preinvasive stage for varying lengths of time. These studies suggest that changes in ezrin may be associated with the development of the invasive phenotype and penetration of the basement membrane. They also raise the possibility that inhibiting ezrin expression could be a target for the prevention of invasive CXCA. PMID- 27688239 TI - Expression of the anaphylatoxin C5a receptor in gastric cancer: implications for vascular invasion and patient outcomes. AB - The C5a receptor (C5aR) expressed in various types of cancers is involved in C5a induced cancer cell invasion. However, its role in gastric cancer has not yet been fully elucidated. Therefore, we studied the clinical significance of C5aR expression in gastric cancer. The association of C5aR expression in gastric cancer, determined by immunostaining using the anti-C5aR antibody, with clinicopathological parameters and outcomes was evaluated in 148 patients. Further, the association of C5aR expression in liver metastatic sites with clinicopathological parameters was investigated in a separate cohort of 58 patients who underwent hepatectomy. High tumoral C5aR expression (n = 45, 30.4 %) was significantly related to tumor location, cancer invasion depth, vascular and lymphatic invasion, and tumor stage. The 5-year recurrence-free and overall survival rates of patients with high tumoral C5aR expression were significantly lower than those of patients with low tumoral C5aR expression (50.9 vs. 84.2 %, P = 0.002 and 58.8 vs. 86.1 %, P = 0.007, respectively). The incidence of liver metastasis was significantly higher in patients with high tumoral C5aR expression (13.3 %) than in those with low tumoral C5aR expression (3.9 %; P = 0.04). C5aR expression at liver metastatic sites was associated with the C5aR expression status at the primary site (P = 0.0004), vascular invasion at the primary site (P = 0.04), and tumor size at the metastatic site (P = 0.01). C5aR expression in gastric cancer was associated with cancer progression, liver metastasis, and poor prognosis. Therefore, C5aR may represent a prognostic factor and therapeutic target in gastric cancer. PMID- 27688242 TI - Both the Suprachiasmatic Nucleus and the Superior Ovarian Nerve Contribute to the Processes of Ovulation and Steroid Hormone Secretion on Proestrus. AB - The aims of the present study were to analyze if the superior ovarian nerve (SON) plays a role in the neural signals from suprachiasmatic nucleus (SCN) that lead to ovulation and ovarian steroids secretion on proestrus day. Rats on proestrus day were treated at 11.00 to 11.30 or 17.00 to 17.30 hours with 1 of the 3 experimental procedures (1) unilateral or bilateral SON sectioning, (2) unilateral or bilateral injury to the SCN, or (3) unilateral injury to the SCN followed by unilateral sectioning of the SON ipsilateral to the treated SCN. Treatments were evaluated 24 hours after surgical procedures. Compared to laparotomized animals, right or bilateral SON sectioning treatment at 17.00 hours resulted in lower ovulation rates and number of ova shed by the right ovary. The ovaries of nonovulating animals showed early follicular luteinization signs and trapped ova. Bilateral SCN injury treatment at 11.00 hours resulted in anovulation; whereas right SCN injury treatment, with or without right SON sectioning, resulted in a lower number of ova shed. Injecting luteinizing hormone releasing hormone to animals with bilateral SCN injury restored ovulation. In rats with unilateral or bilateral SON sectioning, or with injury to the SCN with or without unilateral sectioning of the SON, the effects on hormone levels depended of the hormone studied and the time of day treatment was performed. The present results suggest that on proestrus day, the role of the right or both SON in ovulation and steroid hormone secretion regulation takes place through different neuroendocrine mechanisms from SCN. PMID- 27688243 TI - Follicular Volume Predicts Oocyte Maturity: A Prospective Cohort Study Using Three-Dimensional Ultrasound and SonoAVC. AB - The aim of this study was to investigate whether the automatic measurement of follicular volume by three-dimensional (3D) ultrasound can predict the number of mature oocytes retrieved. A prospective cohort study including 47 women undergoing in vitro fertilization was conducted in a private fertility center. Follicular growth was monitored both manually and automatically using 3D scanning with SonoAVC on the day of human chorionic gonadotropin (hCG) administration. Regression analysis showed that under a standard protocol for hCG administration, the count of mature oocytes is well predicted by a multivariate model including the counts of follicles in the volume classes 2.00 to 5.00 cm3, 1.50 to 1.99 cm3, 1.00 to 1.49 cm3, and 0.60 to 0.99 cm3 In conclusion, this study shows that follicular volume as measured by SonoAVC on the day of hCG administration can be useful to predict oocyte maturity. Specifically, larger follicles and smaller size follicles (class 0.60-0.99 cm3) contribute to the mature oocyte count. This finding warrants the design of clinical trials to establish new criteria for hCG administration based on follicular volume. PMID- 27688244 TI - Endometriosis-Derived Thromboxane A2 Induces Neurite Outgrowth. AB - Hyperinnervation in endometriosis is now well documented, but so far only a few neurotrophins have been identified. Since endometriotic stromal cells secrete thromboxane A2 (TXA2), we sought to determine whether TXA2, derived from endometriotic stromal cells, induces neurite outgrowth. Using primary sensory neurons derived from rat dorsal root ganglia (DRG) and ectopic endometrial stromal cells (EESCs) derived from human ovarian endometrioma tissues, we treated the primary neurons with different concentrations of U-46619, a stable TXA2 mimetic, and performed a neuronal growth assay. The primary neurons were also cocultured with a vehicle, nerve growth factor (NGF, serving as a positive control), the supernatant of EESC culture medium, or the supernatant of EESCs pretreated with ozagrel, a thromboxane synthase inhibitor, and a neuronal growth assay was performed. The total neurite length was evaluated through immunofluorescence microscopy. We found that U-46619 significantly increased the neurite outgrowth in DRG neurons in a concentration-dependent fashion ( P < .001). It also increased the number of neurite ends in a concentration-dependent fashion. Ozagrel treatment alone had no effect on the neurite growth ( P > .05), and the treatment with the supernatant of EESCs induced neurite outgrowth just as potently as that treated with NGF (positive control; P > .05). Remarkably, treatment with the EESC supernatant increased the neurite outgrowth by nearly 3 fold as compared with the control ( P < .01), but the pretreatment with ozagrel abolished the stimulatory effect of the EESC by 31.3% ( P < .05). These findings indicate that EESCs potently induce neurite outgrowth, and endometriosis-derived TXA2 is responsible, at least in part, for this neurotrophic effect. PMID- 27688245 TI - When a Baby Dies: A Systematic Review of Experimental Interventions for Women After Stillbirth. AB - OBJECTIVES: To identify and evaluate intervention studies (ie, experimental study in which the participants undergo some kind of intervention in order to evaluate its impact) that target mental and/or physical health outcomes in women who have experienced stillbirth and to provide specific recommendations for future research and intervention work. METHODS: A librarian conducted an initial search using CINAHL, Cochrane Library, PsycInfo, PubMed, SocIndex, and Web of Knowledge in the spring of 2016. Reference mining provided further articles. Articles were eligible if they were: (1) published in English, (2) published in a peer-reviewed journal, (3) published in 1980 or later, (4) an intervention that evaluated (qualitative or quantitative methods) mental and/or physical health, and (5) included women who had experienced a stillbirth (in utero fetal death at >=20 weeks of gestation). RESULTS: The combined searches produced 2733 articles (including duplicates). After duplicate articles were removed (n = 928), the research team screened the titles, abstracts, and full texts (when necessary) for eligibility (n = 1805). Two articles were identified that met our eligibility criteria. Conclusion for Practice: There is a lack of intervention research in women with stillbirth. It is imperative to develop and implement interventions to improve both mental and physical health in this population, especially in the interconception period (ie, stillbirth aftercare). Future intervention research is needed to determine appropriate support and efficacious delivery of support interventions, feasibility and effectiveness of physical activity interventions and complementary approaches, appropriate timing and dose of interventions, and culturally sensitive interventions appropriate for racial/ethnic minority women with stillbirth. PMID- 27688246 TI - Adiponectin: possible link between metabolic stress and oxidative stress in the elderly. AB - OBJECTIVE: The aim of this study was to evaluate the relationships between the serum levels of adiponectin and systemic oxidative stress exerted on lipids, proteins, as well as endothelial function and cardiovascular diseases (CVD) risk markers, in elderly subjects with metabolic syndrome (MS). METHODS: The serum advanced glycation and oxidation protein products, low-density lipoprotein susceptibility to oxidation (oxLDL), nitric oxide metabolic pathway products (NOx), serum lipid peroxidation, as well as total antioxidant/oxidative capacity (TAC/TOC), were analyzed in elderly subjects with MS (n = 44), compared to aged matched control (n = 39). RESULTS: We pointed out significantly lower levels of adiponectin in elderly MS subjects concomitantly with significantly higher levels of oxidative stress and CVD risk markers. Significant positive correlations were found between serum adiponectin levels and HDL-cholesterol (p < 0.05) and the total cholesterol/LDL-cholesterol ratio (p < 0.01). Additionally, adiponectin levels were significantly inversely associated with insulin resistance index (HOMA-IR, r = -0.348; p < 0.05) and serum lipid peroxidation (r = -0.337; p < 0.05), and significantly positively with the antioxidant capacity (TAC, r = 0.339; p < 0.05). Conversely, adiponectin levels were significantly negatively (r = -0.310; p < 0.05) associated with serum uric acid concentration. CONCLUSIONS: The major protective role of adiponectin versus stress related to an impaired glucose and lipid metabolism suggests that adiponectin plays a critical role in adiposity-related metabolic stress and redox homeostasis. PMID- 27688248 TI - Synergistic protective effect of paeoniflorin and beta-ecdysterone against rotenone-induced neurotoxicity in PC12 cells. AB - There are several factors, like oxidative stress and neurons loss, involving neurodegenerative diseases such as Parkinson's disease (PD). The combination of antioxidant and anti-apoptotic agent is becoming a promising approach to fight against PD. This study evaluates the hypothesis that paeoniflorin (PF) and beta ecdysterone (beta-Ecd) synergize to protect PC12 cells against toxicity induced by PD-related neurotoxin rotenone. The combination of PF and beta-Ecd, hereafter referred to as the PF/beta-Ecd, at suboptimal concentrations increased the viability of rotenone-exposed PC12 cells in a synergistic manner. PF and beta-Ecd cooperate to attenuate the rotenone-induced apoptosis by decrease in Bax expression, caspase-9 activity, and caspase-3 activity. PF or PF/beta-Ecd, but not beta-Ecd, inhibited rotenone-triggered protein kinase C-deltakinase C-delta (PKCdelta) upregulation and nuclear factor kappaB (NF-kappaB) activation. beta Ecd or PF/beta-Ecd, but not PF, enhanced serine/threonine protein kinase (Akt) activation, promoted nuclear factor E2-related factor 2 (Nrf2) nuclear accumulation, suppressed reactive oxygen species (ROS) production. Neuroprotection of PF/beta-Ecd could be completely blocked by PKCdelta inhibitor rottlerin plus Akt specific inhibitor LY294002. Dual blockade of the PKCdelta/NF kappaB pathway by PF and activation of Akt/Nrf2 pathway by beta-Ecd results in a synergistic neuroprotective effect against rotenone-induced neurotoxicity in vitro. These findings provide the rationale for determining the in vivo activity of combined therapy with PF and beta-Ecd against PD. PMID- 27688247 TI - Higher levels of different muscarinic receptors in the cortex and hippocampus from subjects with Alzheimer's disease. AB - It has been suggest that drugs specifically targeting muscarinic receptors will be useful in treating Alzheimer's disease. We decided to determine if the response to such drugs may be altered, because of changes in the levels of muscarinic receptors in the CNS from subjects with the disorder. We used in situ radioligand binding with autoradiography to measure the levels of [3H]pirenzepine binding to muscarinic M1 receptors, [3H]AF-DX 386 binding to muscarinic M1, M2, and M4 receptors, and [3H]4-DAMP binding to muscarinic M1 and M3 receptors in the dorsolateral prefrontal cortex and hippocampus from subjects with Alzheimer's and age/sex-matched controls. Compared with controls, [3H]pirenzepine binding was higher in the dentate gyrus from subjects with Alzheimer's disease. [3H]AF-DX 386 binding was higher in the subiculum and parahippocampal gyrus from subjects with the disorder. In Alzheimer's disease, [3H]-DAMP binding was higher in the dorsolateral prefrontal cortex but not different in the hippocampus. Our data show complex changes in the levels of muscarinic receptors in the CNS from subjects with Alzheimer's disease which may affect clinical response to treatment with drugs-targeting these receptors. PMID- 27688250 TI - Engaging research participants to inform the ethical conduct of mobile imaging, pervasive sensing, and location tracking research. AB - Researchers utilize mobile imaging, pervasive sensing, social media, and location tracking (MISST) technologies to observe and intervene with participants in their natural environment. The use of MISST methods and tools introduces unique ethical issues due to the type and quantity of data, and produces raising new challenges around informed consent, risk assessment, and data management. Since MISST methods are relatively new in behavioral research, there is little documented evidence to guide institutional review board (IRB) risk assessment and inform appropriate risk management strategies. This study was conducted to contribute the participant perspectives when considering ethical and responsible practices. Participants (n = 82) enrolled in an observational study where they wore several MISST devices for 1 week completed an exit survey. Survey items focused on the following: 1-device comfort, 2-informed consent, 3-privacy protections, and 4 bystander engagement. The informed consent process reflected participant actual experience. Device comfort and privacy were raised as concerns to both the participants and bystanders. While the majority of the participants reported a positive experience, it is important to note that the participants were volunteers who were not mandated to wear tracking devices and that persons who are mandated may not have a similar response. Findings support strategies proposed in the Kelly et al. (2013) ethical framework, which emphasizes procedures to improve informed consent, protect privacy, manage data, and respect bystander rights when using a wearable camera.

PMID- 27688249 TI - Implementation evaluation of the Telephone Lifestyle Coaching (TLC) program: organizational factors associated with successful implementation. AB - The Telephone Lifestyle Coaching (TLC) program provided telephone-based coaching for six lifestyle behaviors to 5321 Veterans at 24 Veterans Health Administration (VHA) medical facilities. The purpose of the study was to conduct an evaluation of the TLC program to identify factors associated with successful implementation. A mixed-methods study design was used. Quantitative measures of organizational readiness for implementation and facility complexity were used to purposively select a subset of facilities for in-depth evaluation. Context assessments were conducted using interview transcripts. The Consolidated Framework for Implementation Research (CFIR) was used to guide qualitative data collection and analysis. Factors most strongly correlated with referral rates included having a skilled implementation leader who used effective multi-component strategies to engage primary care clinicians as well as general clinic structures that supported implementation. Evaluation findings pointed to recommendations for local and national leaders to help anticipate and mitigate potential barriers to successful implementation.

PMID- 27688254 TI - Limited Influence of Urban Stormwater Runoff on Salt Marsh Platform and Marsh Creek Oxygen Dynamics in Coastal Georgia. AB - Oxygen concentrations and oxygen utilization rates were monitored continuously for 23 months on marsh platforms and in small tidal creeks at two sites in coastal Georgia, USA, that receive urban stormwater runoff via an extensive network of drainage canals. These data were compared to nearby control sites that receive no significant surface runoff. Overall, rainfall and runoff per se were not associated with differences in the oxygen dynamics among the different locations. Because of the large tidal range and long tidal excursions in coastal Georgia, localized inputs of stormwater runoff are rapidly mixed with large volumes of ambient water. Oxygen concentrations in tidal creeks and on flooded marsh platforms were driven primarily by balances of respiration and photosynthesis in the surrounding regional network of marshes and open estuarine waters. Local respiration, while measurable, was of relatively minor importance in determining oxygen concentrations in tidal floodwaters. Water residence time on the marshes could explain differences in oxygen concentration between the runoff-influenced and control sites. PMID- 27688255 TI - A Large-Scale, Multiagency Approach to Defining a Reference Network for Pacific Northwest Streams. AB - Aquatic monitoring programs vary widely in objectives and design. However, each program faces the unifying challenge of assessing conditions and quantifying reasonable expectations for measured indicators. A common approach for setting resource expectations is to define reference conditions that represent areas of least human disturbance or most natural state of a resource characterized by the range of natural variability across a region of interest. Identification of reference sites often relies heavily on professional judgment, resulting in varying and unrepeatable methods. Standardized methods for data collection, site characterization, and reference site selection facilitate greater cooperation among assessment programs and development of assessment tools that are readily shareable and comparable. We illustrate an example that can serve the broader global monitoring community on how to create a consistent and transparent reference network for multiple stream resource agencies. We provide a case study that offers a simple example of how reference sites can be used, at the landscape level, to link upslope management practices to a specific in-channel response. We found management practices, particularly areas with high road densities, have more fine sediments than areas with fewer roads. While this example uses data from only one of the partner agencies, if data were collected in a similar manner they can be combined and create a larger, more robust dataset. We hope that this starts a dialog regarding more standardized ways through inter-agency collaborations to evaluate data. Creating more consistency in physical and biological field protocols will increase the ability to share data. PMID- 27688256 TI - Using Different Grazing Practices for Increasing Plant Biodiversity in the Dykes and Embankments Along the Rhone River (Southern France). AB - Extensive grazing by domestic herbivores is a widespread management practice used since the 80s in many European agro-ecosystems such as semi-natural grasslands to maintain open habitats and to enhance biodiversity. Such grazing systems have principally been tested in cultural ecosystems of high nature value threatened by grazing abandonment. However, there have been few case studies of grazing management in very anthropized ecosystems, such as the new ecosystems created by urban or industrial conversions. In Southern France, the Rhone channeling for navigation and electricity production generated in the 1950s the construction of thousands of hectares of dams and dykes which were colonized naturally by diverse plant communities. Yet shrub encroachment and the consequent recourse to mechanical cutting to facilitate control and maintenance, raise the question of how best to maintain and manage these new habitats. Consequently, since 1999, different low-intensity grazing management systems using rustic breeds of cattle, horses and goats have been tested on a protected reserve of 1454 ha located in the lower part of the Rhone river. Extensive grazing, more than cutting or no management, positively modified vegetation heterogeneity (beta-diversity), the target open grassland species, but not plant species richness (alpha-diversity). However, the current monitoring shows that these benefits of grazing will be confirmed only if low-intensity grazing systems are sustained and if new adaptations can be also made, such as the use of mixed stocking and the establishment of multiyear contracts with breeders. PMID- 27688257 TI - Cranes and Crops: Investigating Farmer Tolerances toward Crop Damage by Threatened Blue Cranes (Anthropoides paradiseus) in the Western Cape, South Africa. AB - The Western Cape population of Blue Cranes (Anthropoides paradiseus) in South Africa is of great importance as the largest population throughout its range. However, Blue Cranes are strongly associated with agricultural lands in the Western Cape, and therefore may come into conflict with farmers who perceive them as damaging to crops. We investigated the viability of this population by exploring farmer attitudes toward crane damage in two regions of the Western Cape, the Swartland and Overberg, using semi-structured interviews. Perceptions of cranes differed widely between regions: farmers in the Swartland perceived crane flocks to be particularly damaging to the feed crop sweet lupin (65 % of farmers reported some level of damage by cranes), and 40 % of these farmers perceived cranes as more problematic than other common bird pests. Farmers in the Overberg did not perceive cranes as highly damaging, although there was concern about cranes eating feed at sheep troughs. Farmers who had experienced large flocks on their farms and farmers who ranked cranes as more problematic than other bird pests more often perceived cranes to be damaging to their livelihoods. Biographical variables and crop profiles could not be related to the perception of damage, indicating the complexity of this human-wildlife conflict. Farmers' need for management alternatives was related to the perceived severity of damage. These results highlight the need for location-specific management solutions to crop damage by cranes, and contribute to the management of this vulnerable species. PMID- 27688259 TI - Pre-hospital identification and post-recovery challenges of intoxication with synthetic cannabinoid containing legal high products such as 'Exodus Damnation'. AB - This short report describes the case of a young adult male who had smoked a synthetic cannabinoid legal high product called 'Exodus Damnation'. The patient's presentation was atypical from that described in the literature, with hypotension and hypoxaemia. Of note was the rapid recovery after pre-hospital intervention with high-flow oxygen therapy and intravenous fluids. The patient refused on going care, despite repeated advice to attend the Emergency Department. The distinct lack of specialist support and referral to drug treatment for this patient population, with whom ambulance services are coming into contact with increasing frequency, is reported. For those patients with the capacity to refuse on-going care, ambulance services may be in an opportune position to actively promote referral to support services for these vulnerable individuals. PMID- 27688258 TI - Quantitation of isobaric phosphatidylcholine species in human plasma using a hybrid quadrupole linear ion-trap mass spectrometer. AB - Phosphatidylcholine (PC) species in human plasma are used as biomarkers of disease. PC biomarkers are often limited by the inability to separate isobaric PCs. In this work, we developed a targeted shotgun approach for analysis of isobaric and isomeric PCs. This approach is comprised of two MS methods: a precursor ion scanning (PIS) of mass m/z 184 in positive mode (PIS m/z +184) and MS3 fragmentation in negative mode, both performed on the same instrument, a hybrid triple quadrupole ion-trap mass spectrometer. The MS3 experiment identified the FA composition and the relative abundance of isobaric and sn-1, sn 2 positional isomeric PC species, which were subsequently combined with absolute quantitative data obtained by PIS m/z +184 scan. This approach was applied to the analysis of a National Institute of Standards and Technology human blood plasma standard reference material (SRM 1950). We quantified more than 70 PCs and confirmed that a majority are present in isobaric and isomeric mixtures. The FA content determined by this method was comparable to that obtained using GC with flame ionization detection, supporting the quantitative nature of this MS method. This methodology will provide more in-depth biomarker information for clinical and mechanistic studies. PMID- 27688260 TI - Echocardiographic associates of atrial fibrillation in end-stage renal disease. AB - Background: The prevalence of atrial fibrillation (AF) in end-stage renal disease (ESRD) patients is relatively high. The present study evaluated the association between left atrial (LA) remodelling, including an increased size and myocardial fibrosis, and slow LA conduction and the occurrence of AF. Methods: In 171 ESRD patients enrolled in the Implantable Cardioverter Defibrillators in Dialysis patients (ICD2) trial, the LA dimensions, LA conduction delay [as reflected by the time difference between P-wave onset on surface electrocardiogram and A'-wave on tissue Doppler imaging (PA-TDI)] and LA function were compared between patients who exhibited AF versus patients without AF. Based on ICD remote monitoring or clinical records, the occurrence of AF was detected. Results: Of 171 patients, 47 (27%) patients experienced AF. Despite comparable left ventricular ejection fraction and prevalence of significant mitral regurgitation, patients with AF had significantly larger LA volume index (mean +/- standard deviation) (29 +/- 11 versus 23 +/- 10 mL/m2, P = 0.001), longer PA-TDI duration (144 +/- 30 versus 131 +/- 27 ms, P = 0.010) and reduced late diastolic mitral annular velocity (A') (7.1 +/- 2.8 versus 8.2 +/- 2.4 cm/s, P = 0.012) compared with patients without AF. On multivariable analysis, larger LA volume index [odds ratio (OR) 1.04, 95% confidence interval (CI) 1.01-1.08, P = 0.017], longer PA TDI duration (OR 1.02, 95% CI 1.00-1.03, P = 0.025) and reduced A' (OR 0.84, 95% CI 0.72-0.98, P = 0.025) were independently associated with AF after adjusting for age and left ventricle diastolic relaxation. Conclusion: ESRD patients with AF show more advanced changes in the LA substrate than ESRD patients without AF. PMID- 27688261 TI - Optical Coherence Tomography Predictors for Edge Restenosis After Everolimus Eluting Stent Implantation. AB - BACKGROUND: Stent edge restenosis (SER) remains a potential limitation of drug eluting stents. The aim of this study was to determine optical coherence tomography (OCT) predictors for angiographic late SER after everolimus-eluting stent implantation. METHODS AND RESULTS: We retrospectively analyzed 319 patients who underwent OCT immediately after everolimus-eluting stent implantation and scheduled 9- to 12-month follow-up angiography. The binary angiographic SER rate was 10% (32/319) in the patients, 8.4% (32/382) in lesions, and 4.4% (33/744) in stent edge segments. In the stent edge segments at post stenting, OCT-derived lipidic plaque (61% versus 20%; P<0.001) was more often observed in the SER group, and OCT-measured minimum lumen area (4.13+/-2.61 versus 5.58+/-2.46 mm2; P=0.001) was significantly smaller in the SER group compared with the non-SER group. Multivariate analysis identified lipidic plaque (odds ratio: 5.99; 95% confidence interval: 2.89-12.81; P<0.001) and minimum lumen area (odds ratio: 0.64; 95% confidence interval: 0.42-0.96; P=0.029) as independent predictors of binary SER. Receiver-operating characteristic analysis demonstrated that lipid arc of 185 degrees (sensitivity: 71%; specificity: 72%; area under the curve: 0.761) and minimum lumen area of 4.10 mm2 (sensitivity: 67%; specificity: 77%; area under the curve: 0.787) were optimal cutoff values for predicting ischemia driven SER. CONCLUSIONS: The present OCT study demonstrated that lipidic plaque and minimum lumen area in the stent edge segments at post stenting were associated with late SER after everolimus-eluting stent implantation. OCT provides valuable information to determine an appropriate landing zone for stent implantation. PMID- 27688264 TI - Supercollision cooling effects on the hot photoluminescence emission of graphene. AB - We report on hot photoluminescence measurements that show the effects of acoustic phonon supercollision processes in the intensity of graphene light emission. We use a simple optical method to induce defects on single layer graphene in a controlled manner to study in detail the light emission dependence on the sample defect density. It is now well accepted that the graphene photoluminescence is due to black-body thermal emission from the quasi-equilibrium electrons at a temperature well above the lattice temperature. Our results show that as the sample defect density is increased the electrons relax energy more efficiently via acoustic phonon supercollision processes leading to lower electron temperatures and thus lower emission intensities. The calculated intensity decrease due to supercollision energy relaxation agrees well with the experimental data. PMID- 27688262 TI - The Prognostic Effect of MAC30 Expression on Patients With Non-Small Cell Lung Cancer Receiving Adjuvant Chemotherapy. AB - The purpose of this study was to examine the MAC30 expression in non-small cell lung cancer and to evaluate its prognostic value on therapeutic response in patients with non-small cell lung cancer receiving postoperative chemotherapy. Among a total of 218 retrospective Chinese patients with non-small cell lung cancer, 164 patients receiving adjuvant chemotherapy were enrolled in this study. Real-time polymerase chain reaction was performed to confirm the expression of MAC30 messenger RNA in 32 cases of non-small cell lung cancer tumors with the corresponding nontumor lung tissues. The MAC30 protein expression in all specimens was analyzed by immunohistochemical staining. Moreover, we assessed the correlation of MAC30 expression with clinicopathological features, therapeutic response, and survival of patients. Here, we observed the increased expression of MAC30 messenger RNA in patients with non-small cell lung cancer compared to those in control samples. The overexpression of MAC30 was strongly associated with poor tumor differentiation, high tumor-node-metastasis stage, and lymph node metastasis. In addition, we observed that patients with increased MAC30 expression showed gloomy overall survival and disease-free survival. A multivariate analysis explicated that higher MAC30 expression was a valuable independent prognostic factor of poorer tumor differentiation, shorter overall survival, and disease-free survival in patients receiving chemotherapy. MAC30 could be a useful biomarker of tumor differentiation and outcome of patients with non-small cell lung cancer. Overexpression of MAC30 predicts a worse tumor differentiated stage and prognosis in patients with non-small cell lung cancer receiving adjuvant chemotherapy. PMID- 27688265 TI - Effect of V/III ratio on the structural and optical properties of self-catalysed GaAs nanowires. AB - The performance of GaAs nanowire (NW) devices depends critically on the presence of crystallographic defects in the NWs such as twinning planes and stacking faults, and considerable effort has been devoted to understanding and preventing the occurrence of these. For self-catalysed GaAs NWs grown by molecular beam epitaxy (MBE) in particular, there are in addition other types of defects that may be just as important for NW-based optoelectronic devices. These are the point defects such as the As vacancy and the Ga antisite occurring due to the inherently Ga-rich conditions of the self-catalysed growth. Here we demonstrate experimentally the effects of these point defects on the optical properties of GaAs/AlGaAs core-shell NWs grown by self-catalysed MBE. The present results enable insight into the role of the point defects both on their own and in conjunction with crystallographic planar defects. PMID- 27688263 TI - Integrating molecular markers into the World Health Organization classification of CNS tumors: a survey of the neuro-oncology community. AB - Background: Molecular markers provide important biological and clinical information related to the classification of brain tumors, and the integration of relevant molecular parameters into brain tumor classification systems has been a widely discussed topic in neuro-oncology over the past decade. With recent advances in the development of clinically relevant molecular signatures and the 2016 World Health Organization (WHO) update, the views of the neuro-oncology community on such changes would be informative for implementing this process. Methods: A survey with 8 questions regarding molecular markers in tumor classification was sent to an email list of Society for Neuro-Oncology members and attendees of prior meetings (n=5065). There were 403 respondents. Analysis was performed using whole group response, based on self-reported subspecialty. Results: The survey results show overall strong support for incorporating molecular knowledge into the classification and clinical management of brain tumors. Across all 7 subspecialty groups, >=70% of respondents agreed to this integration. Interestingly, some variability is seen among subspecialties, notably with lowest support from neuropathologists, which may reflect their roles in implementing such diagnostic technologies. Conclusion: Based on a survey provided to the neuro-oncology community, we report strong support for the integration of molecular markers into the WHO classification of brain tumors, as well as for using an integrated "layered" diagnostic format. While membership from each specialty showed support, there was variation by specialty in enthusiasm regarding proposed changes. The initial results of this survey influenced the deliberations underlying the 2016 WHO classification of tumors of the central nervous system. PMID- 27688266 TI - Race and Religious Beliefs Are Associated With Communication Regarding Reproductive Health and Preconception Counseling in Young Women With Diabetes. AB - PURPOSE: The purpose of this study was to examine the relationship between selected internal and external characteristics and communication (intended and actual) with health care providers (HCPs) about reproductive health and preconception counseling among adolescent females with diabetes. METHODS: A descriptive, correlational design was employed to conduct a secondary analysis of baseline data from a multisite, randomized controlled trial. Participants were 110 female adolescents (92% type 1 diabetes). Analysis included multiple linear regression and multivariate binary logistic regression analyses to examine the association of internal characteristics (age, race, religion, and religious beliefs) and external characteristics (ever sexually active, social support, and type of routine HCP). RESULTS: Participants were from 13.3 to 20.0 years of age, 82% were Caucasian, 80% had never been sexually active, and 58% perceived low to moderate amounts of social support. For both internal and external characteristics, no significant main effects were found for actual or intended communication. For internal characteristics, there was an interaction between race and religious beliefs for the probability of actual communication. African American women who reported that their religious beliefs did not influence their sexual behavior had the lowest probability of actual communication compared to all other participants. CONCLUSION: Race and religious beliefs should be considered when providing reproductive health information to young women with diabetes. Further research with a larger, more diverse sample is warranted. These results may be considered for future development of novel interventions with targeted messages based on these personal characteristics to empower young women to initiate conversations with HCPs about reproductive health and preconception counseling. PMID- 27688268 TI - Identifying and mapping the polytypes and orientation relationships in ZnO/CdSe core-shell nanowire arrays. AB - Identifying and mapping the crystalline phases and orientation relationships on the local scale in core-shell ZnO nanowire heterostructures are of primary importance to improve the interface quality, which governs the performances of the nanoscale devices. However, this represents a major difficulty, especially when the expected polytypes exhibit very similar properties as in the case of CdSe. In the present work, we address that issue in ZnO nanowire heterostructures involving a uniform and highly conformal CdSe shell grown by molecular beam epitaxy. It is shown by x-ray diffraction and Raman spectroscopy through the occurrence of the (1010) and (1011) diffraction peaks and of the [Formula: see text] mode at 34 cm-1, respectively, that the CdSe shell is mostly crystallized into the wurtzite phase. By using automated crystal phase and orientation mapping with precession (ASTAR) in a transmission electron microscope and thus by benefiting from highly precise electron diffraction patterns, the CdSe shell is found to crystallize also into the minority zinc blende phase. The wurtzite CdSe shell is epitaxially grown on the top of ZnO nanowires, and some specific orientation relationships are mapped and revealed when grown on their vertical sidewalls. Zinc blende CdSe domains are also formed exclusively in the center of wurtzite CdSe grains located on the vertical sidewalls; both wurtzite and zinc blende CdSe crystalline phases have a strong orientation relationship. These findings reveal that ASTAR is a powerful technique to elucidate the structural properties on the local scale and to gain a deeper insight into their crystalline phases and orientation relationships, which is highly promising for many types of semiconducting nanowire heterostructures. PMID- 27688267 TI - Vessel perforation during stent retriever thrombectomy for acute ischemic stroke: technical details and clinical outcomes. AB - BACKGROUND: Vessel perforation during stent retriever thrombectomy is a rare complication; typically only single instances have been reported. OBJECTIVE: To report on a series of patients whose stent retriever thrombectomy was complicated by intraprocedural vessel perforation and discuss its potential mechanisms, rescue treatment strategies, and clinical significance. METHODS: Cases with intraprocedural vessel perforation, where a stent retriever was used either as a primary treatment approach or as a part of a direct aspiration first pass technique (ADAPT), were included in the final analysis. Clinical data, procedural details, radiographic and clinical outcomes were collected from nine participating centers. RESULTS: Intraprocedural vessel perforation during stent retriever thrombectomy occurred in 16 (1.0%) of 1599 cases. 63% of intraprocedural perforations occurred at distal locations. Endovascular rescue techniques (most commonly, intracranial balloon occlusion for tamponade) were attempted in 50% of cases. Procedure was aborted without any rescue attempts in 44% of cases. Mortality during hospitalization and at 3 months was 56% and 63%, respectively. 25% of patients achieved good functional outcome at 3 months after the procedure. CONCLUSIONS: Intraprocedural perforations during stent retriever thrombectomy were rare, but when they occurred were associated with high mortality. Perforations most commonly occurred at distal occlusion sites and were often characterized by difficulty traversing the occlusion with a microcatheter or microwire, or while withdrawing the stent retriever. Nevertheless, 25% of patients had a favorable functional outcome, suggesting that in some patients with this complication good neurological recovery is achievable. PMID- 27688273 TI - The emerging battlefront: Infectious diseases. PMID- 27688274 TI - Clinical spectrum, diagnostic criteria, and polymerase chain reaction of aqueous humor in viral and toxoplasma detection in Fuchs' uveitis syndrome. AB - AIM: The aim of this study is to describe the clinical features and diagnostic criteria of Fuchs' uveitis (FU) and to determine whether it has an association with virus and toxoplasma in the aqueous humor during cataract surgery. SETTING AND DESIGN: This is a prospective, case-control study. MATERIALS AND METHODS: Patients with FU (n = 25), anterior uveitis (n = 15), and no uveitis (normal) (n = 50) were included based on predefined inclusion and exclusion criteria for all three groups. Polymerase chain reaction (PCR) of aqueous humor and serum for rubella, herpes simplex virus (HSV), cytomegalovirus (CMV), varicella-zoster virus (VZV), and toxoplasma was done using conventional uniplex PCR. STATISTICAL ANALYSIS: It was done using SPSS software using Chi-square test for categorical variables, and P < 0.05 was considered statistically significant. RESULTS: Ninety patients were enrolled in the study in three groups, comparable for age, gender, and laterality of ocular involvement. All patients had diffuse keratic precipitates in FU group (P = 0001) with none having posterior synechiae (P = 0.046) which was statistically significant when compared to anterior uveitis patients. Iris nodules were noted in one case in both groups. Serum and aqueous PCR was negative for detection of VZV, CMV, toxoplasma, and rubella in all groups. PCR for HSV was positive in one patient in "normal" group but was not statistically significant. CONCLUSION: Our study shows that diagnosis of FU is mainly clinical. There appears to be no role of aqueous humor testing for viruses by PCR to aid in etiological diagnosis. PMID- 27688275 TI - Anterior stromal puncture with staining: A modified technique for preoperative reference corneal marking for toric lenses and its retrospective analyses. AB - INTRODUCTION: Toric intraocular lenses (IOLs) are an effective way of compensating preexisting corneal astigmatism during cataract surgery. To achieve success, it is imperative to align the toric IOLs in desired position and preoperative reference marking is one among the three important steps for accurate alignment. To make the marking procedure simpler and effective, we have modified the conventional three-step slit lamp-based technique. MATERIALS AND METHODS: Patient is seated in front of the slit lamp and asked to keep the chin over chin rest. A 26-gauge bent needle with tip stained by sterile blue ink marker is used to make anterior stromal puncture (ASP) at the edges of horizontal 180 degrees axis near the limbus. RESULTS: A total of 58 eyes were retrospectively evaluated. Mean (+/-SD) IOL deviation on day 1 and day 30 was 5.7 +/- 6.5 degrees and 4.7 +/- 5.6 degrees , respectively. Median IOL misalignment on day 1 and day 30 was 3 degrees . Redialing of IOL was required in 2 (3.4%) eyes only, all of which were performed within 1 week of surgery. In total, 2 (3.7%) eyes had a residual astigmatism of - 0.5 Dcyl and - 1.0 Dcyl, respectively. CONCLUSION: ASP is an effective technique for reference marking, technically simpler and can be practiced by most of the surgeons. It avoids the necessity of high-end sophisticated machinery and gives a better platform for the reference corneal marking along with the benefit of reproducibility and simplicity. PMID- 27688276 TI - Repair of 50-75% full-thickness lower eyelid defects: Lateral stabilization as a guiding principle. AB - INTRODUCTION: Repair of large defects of the lower eyelid can be difficult. A common procedure performed to address these defects is a Hughes flap. This procedure has a number of disadvantages: The eye is closed postoperatively, a second stage is required, and the edge of the flap is often erythematous. The purpose of this paper is to describe a one-stage procedure for the repair of large full-thickness defects of the lower lid as an alternative to a Hughes flap. MATERIALS AND METHODS: This is a retrospective study of patients who underwent the described procedure. The procedure employs lateral stabilization of the posterior lamella with a periosteal strip, medial transposition of the lateral posterior lamella for central and medial defects, and a myocutaneous advancement flap to stabilize the anterior lamella. RESULTS: A total of 38 patients underwent the procedure to reconstruct full-thickness defects of the lower lid ranging from 50% to 75%. All patients underwent previous Mohs excision of a skin cancer. The average follow-up was 5.6 months. Eleven patients (29%) had postoperative sequelae, but only two patients (5%) required additional treatment. CONCLUSION: Lateral stabilization with a periosteal strip and myocutaneous advancement flap is an excellent one-step procedure that avoids many of the complications seen with the Hughes procedure and is comparable to other techniques used for the reconstruction of subtotal, full-thickness lower lid defects. PMID- 27688277 TI - Laser intervention on trabeculo-Descemet's membrane after resistant viscocanalostomy: Selective 532 nm gonioreconditioning or conventional 1064 nm neodymium-doped yttrium aluminum garnet laser goniopuncture? AB - PURPOSE: To compare the results of conventional 1064 nm neodymium-doped yttrium aluminum garnet laser goniopuncture (Nd:YAG-GP) and selective 532 nm Nd:YAG laser (selective laser trabeculoplasty [SLT]) gonioreconditioning (GR) on trabeculo Descemet's membrane in eyes resistant to viscocanalostomy surgery. METHODS: Thirty-eight eyes of 35 patients who underwent laser procedure after successful viscocanalostomy surgery were included in the study. When postoperative intraocular pressure (IOP) was above the individual target, the eyes were scheduled for laser procedure. Nineteen eyes underwent 532 nm SLT-GR (Group 1), and the remaining 19 eyes underwent conventional 1064 nm Nd:YAG-GP (Group 2). IOPs before and after laser (1 week, 1 month, 3 months, 6 months, 1 year, and last visit), follow-up periods, number of glaucoma medications, and complications were recorded for both groups. RESULTS: Mean times from surgery to laser procedures were 17.3 +/- 9.6 months in Group 1 and 13.0 +/- 11.4 months in Group 2. Mean IOPs before laser procedures were 21.2 +/- 1.7 mmHg in Group 1 and 22.8 +/- 1.9 mmHg in Group 2 (P = 0.454). Postlaser IOP measurements of Group 1 were 12.1 +/- 3.4 mmHg and 13.8 +/- 1.7 mmHg in the 1 st week and last visit, respectively; in Group 2, these measurements were 13.6 +/- 3.7 mmHg and 14.9 +/- 4.8 mmHg, respectively. There were statistically significant differences (P < 0.001) in IOP reduction at all visits in both groups; the results of the two groups were similar (P > 0.05). Mean follow-up was 16.6 +/- 6.4 months after SLT GR and 18.9 +/- 11.2 months after Nd:YAG-GP. CONCLUSIONS: While conventional Nd:YAG-GP and SLT-GR, a novel procedure, are both effective choices in eyes resistant to viscocanalostomy, there are fewer complications with SLT-GR. SLT-GR can be an alternative to conventional Nd:YAG-GP. PMID- 27688278 TI - Burden and depression in primary caregivers of persons with visual impairment. AB - CONTEXT: Caregivers who assist persons with visual impairment often neglect their needs, resulting in burden and depression. Rehabilitation efforts, directed to the disabled, seldom target the caregiver. AIM: To assess burden and depression in persons caring for blind individuals. SETTINGS AND DESIGN: This was a cross sectional study carried out in the outpatient department of a tertiary-level teaching hospital in New Delhi. MATERIALS AND METHODS: Institutional Ethical Board approval was obtained and written informed consent too was obtained from the participants involved in this study. Persons with best-corrected vision <20/200 in the better eye, and their primary caregivers, were recruited. We recorded demography, other illness/disability, household income, relationship with disabled person, and caregiver burden (Caregiver Burden Scale) and depression (Centre for Epidemiologic Studies Depression Scale). STATISTICAL ANALYSIS: Statistical analysis was carried out using SPSS version 20 (Released 2011. Armonk, NY: IBM Corp.); range, average, and standard deviation were determined for age, burden, and depression. The association between burden and depression was determined using Pearson's correlation; the relationship between degree of disability and caregiver burden and depression was determined using unpaired t-test; using multiple linear regression, factors were found to be statistically significant; significance was taken at P < 0.05. RESULTS: Twenty seven (53.0%) men and 24 (47.0%) women had visual impairment. Most caregivers (n = 40; 81.6%) were first-degree relatives or a spouse; 32 (65%) had schooling <5 years; and 29 (59%) were unemployed. Depression ranged from 21 to 52 (average 43.2 +/- 5.71); it correlated with degree of disability (P = 0.012), household income (r = -0.320; P = 0.025), and burden (r = 0.616; P < 0.001). Burden ranged from 30 to 73 (average 54.5 +/- 6.73) and correlated with degree of disability (P = 0.006). On multiple linear regression, burden predicted depression (r = 0.557; P < 0.001). CONCLUSIONS: Caregivers merit community support, financial benefit, interventions to diagnose and treat depression, and training in coping. Centers that provide disability certification could offer counseling. PMID- 27688279 TI - Prevalence of glaucoma in Eastern India: The Hooghly River Glaucoma Study. AB - CONTEXT: Glaucoma is the leading cause of global irreversible blindness. No recent study with adequate sample size has been carried out to estimate glaucoma prevalence in Eastern India. AIMS: The aim of this study was to assess and compare the prevalence and types of glaucoma in a rural and urban East Indian population. SETTINGS AND DESIGN: The Hooghly River Glaucoma Study (HRGS) is a population-based cross-sectional study from West Bengal. A tertiary hospital in Kolkata was our urban study center. Our rural study area included 28 contiguous villages from the district of Hooghly surrounding the rural base hospital located at Dhobapara in village Bakulia. Individuals aged 40 years and above were included in this study. SUBJECTS AND METHODS: All subjects underwent a detailed ophthalmic examination at our base hospitals including applanation tonometry, ultrasound pachymetry, gonioscopy, and frequency doubling technology perimetry. Glaucoma was defined using modified International Society of Geographical and Epidemiological Ophthalmology criteria. STATISTICAL ANALYSIS USED: Analysis was performed using Chi-square test and multiple logistic regression using SPSS. RESULTS: Totally, 14,092 individuals participated; 2.7% were detected to have glaucoma in rural arm and 3.23% in urban arm (P < 0.001). In urban population, 2.10% had primary open angle glaucoma (POAG), 0.97% had primary angle closure glaucoma (PACG), and 0.15% had secondary glaucoma. In rural population, 1.45% had POAG, 1.15% had ACG, and 0.10% had secondary glaucoma. CONCLUSIONS: HRGS is the largest population-based glaucoma study in India to date with glaucoma prevalence comparable to other landmark Indian studies. POAG was the most common form of glaucoma in our study population as well. PACG was more common in this region than previously thought. PMID- 27688280 TI - To assess surgical outcomes of combined femtosecond laser-assisted cataract surgery with 25-gauge vitrectomy surgery at a tertiary eye care center. AB - BACKGROUND: The aim of this study was to assess the surgical outcomes of combined femtosecond laser-assisted cataract surgery (FLACS) with 25-gauge vitrectomy surgery. MATERIALS AND METHODS: A retrospective analysis of 45 patients who underwent combined FLACS with 25-gauge vitrectomy surgery. RESULTS: A total number of 45 eyes of 45 patients were treated with a mean age of 63.27 years (range 45-75). The mean follow-up was 3 months (range 3-12 months). The mean preoperative best-corrected visual acuity was 1.47 +/- 0.86. The mean postoperative vision was 0.36 +/- 0.36 and 0.275 +/- 0.184 at a paired t-test revealed a statistically significant improvement in visual acuity at 1 month (P < 0.001) and 3 months (P < 0.001). The most common indication for surgery was full thickness macular hole (51.1%), vitreous hemorrhage (24.4%), followed by epiretinal membrane (17.7%) and rhegmatogenous retinal detachment (4.4%). CONCLUSION: Combining FLACS with vitrectomy may be a step toward achieving better outcomes when combined CS and vitrectomy is performed. PMID- 27688281 TI - A treatment method for chronic suppurative lacrimal canaliculitis using chalazion forceps. AB - PURPOSE: The purpose of this study is to evaluate the effectiveness of chronic suppurative lacrimal canaliculitis treatment using chalazion forceps. PATIENTS AND METHODS: A prospective study was performed on consecutive patients who accepted the aid of chalazion forceps to treat chronic suppurative lacrimal canaliculitis. Two different treatment methods using chalazion forceps were performed according to the degree of lacrimal canaliculitis. Postoperatively, the patients received 0.5% levofloxacin eye drops four times per day and 0.5 g oral levofloxacin tablets once per day for 4 days. The follow-up period was more than 3 months. Lacrimal irrigation, the condition of the lacrimal punctum, and patients' symptoms were carefully evaluated. RESULTS: In total, 32 patients met the criteria for chronic suppurative lacrimal canaliculitis. Included were 6 males and 26 females. Their average age was 51.7 +/- 14.9 years (range; 19-80 years), and all had unilateral canaliculitis. The mean duration of the symptoms was 18.9 +/- 9.8 months (range; 3-48 months). The mean follow-up time was 14.7 +/ 7.8 months. The signs and symptoms resolved completely in all patients within 15 days, and no recurrence was observed. No patients reported epiphora after the treatment. CONCLUSIONS: The use of chalazion forceps is effective in treating chronic suppurative lacrimal canaliculitis. The forceps may offer an alternative treatment technology in the management of suppurative lacrimal canaliculitis. PMID- 27688282 TI - Diagnosis and a minimum effective management for nanophthalmic uveal effusion syndrome. PMID- 27688284 TI - Interface infectious keratitis following deep anterior lamellar keratoplasty. AB - A 32-year-old female patient underwent deep anterior lamellar keratoplasty (DALK) in both eyes for advanced keratoconus. She developed an infiltrate in the nasal paracentral interface of the left eye. In view of the paracentral location, localized epithelial removal/stromal scraping was done and the infiltrate was removed using forceps and sent for microbiological assay, which revealed fungal filaments. The patient successfully responded to intensive topical antifungal therapy with the maintenance of visual acuity. Interface keratitis following DALK frequently needs graft lift/interface wash due to deep location, rapid spread and poor penetration and efficacy of topical medications. In view of a paracentral location, modified debulking with topical therapy resulted in a satisfactory outcome in our case thereby avoiding the need for more invasive treatments. PMID- 27688283 TI - Orbital infarction syndrome after multiple percutaneous sclerotherapy sessions for facial low-flow vascular malformation: A case report and literature review. AB - Vision loss following sclerotherapy for facial vascular malformations (VMs) is a rare but detrimental complication. Here, we report a case of an 11-year-old boy with acute onset blepharoptosis, ophthalmoplegia, and blindness in his right eye after the 14 th sclerotherapy session (percutaneous intralesional injection of sodium tetradecyl sulfate) for a right facial low-flow VM without orbital involvement. Computed tomography angiography revealed no contrast enhancement in the right ophthalmic artery, superior ophthalmic vein, or extraocular muscles. He presented with the hallmarks of orbital infarction syndrome: Clear signs of anterior and posterior segment ischemia and disrupted arterial flow to the extraocular muscles. His blepharoptosis and eye movement improved 4 months later; however, he remained blind, and phthisis bulbi developed eventually. Thus, sclerotherapy for facial VM-even without orbital involvement--may result in severe ocular and orbital complications. PMID- 27688285 TI - IgG4-related intraocular inflammation masquerading as ciliary body melanoma in a young girl. AB - Immunoglobulin G4 (IgG4-related diseases) affects various tissues and organs of the human body. Orbital, adnexal, and scleral inflammations were already reported in the medical literature. To the best of our knowledge, we report the first case of intraocular IgG4-associated inflammatory mass in the ciliary body mimicking as a melanoma in a 23-year-old female from Northeast India. Characteristic histopathology, immunohistochemistry in the tissue, protein chemistry, and raised serum IgG4 were supportive for the diagnosis. As this newly diagnosed disease has multi-organ affection and little is known about its pathogenesis particularly in eye and adnexa, the present case will open many challenges in clinico pathological diagnosis and research in the future.

The report highlights notable aspects in diagnosis, decision-making, and successful removal of this unusual case of retro-orbital foreign body. PMID- 27688288 TI - A rare case of Enterococcus faecalis-induced orbital cellulitis and myositis. AB - Orbital cellulitis is an infection of soft tissue behind the orbital septum. Common pathogens isolated include Staphylococcus aureus, Staphylococcus epidermidis, and Streptococcus pneumoniae. It is a straightforward diagnosis and usually responds to empirical treatment without any sequela. We report a case of orbital cellulitis caused by Enterococcus faecalis, which was complicated by myositis of levator palpebrae superioris. To the best of our knowledge, only one case report exists dating way back to 1986. PMID- 27688287 TI - Choroidal neovascular membrane in a treated choroidal hemangioma. AB - Association of choroidal neovascular (CNV) membrane with circumscribed choroidal hemangioma is rare, and the CNV development after photodynamic therapy (PDT) is also rare. Etiopathogenesis of these associations is poorly understood. We noted the development of CNV over choroidal hemangioma after PDT therapy in a young female patient in our hospital. Temporal association of CNV development after PDT treatment points toward the possible side effects of PDT. Repeat injections of antivascular endothelial growth factor (ranibizumab) regressed the CNV resulting in a favorable visual outcome. PMID- 27688289 TI - Ocular toxicity by seeds of Annona squamosa (custard apple). AB - Custard apple seeds have been used in native medicine from time immemorial for the management of head lice and skin exfoliation. We report six consecutive patients who developed toxic keratoconjunctivitis within 6-12 h of ocular exposure to custard apple seeds. The use of topical steroid worsens the toxicity and predisposes to the development of microbial keratitis in such cases. Patients showed a good response to primary treatment with topical fortified antibiotics and lubricants. This case series highlights the need to educate the patients regarding the potential toxic effects of the custard seeds and the treating physicians about possible deleterious effects on using topical steroid.

AB - Background Pelvic vein incompetence is a cause for pelvic pain and recurrent varicose veins in women. The gold standard diagnostic method is reflux venography involving radiation, nephrotoxic contrast and jugular puncture. Trans-vaginal ultrasound (TVU) is increasingly being used as a diagnostic tool for pelvic vein incompetence. Methods Fifty women with clinical suspicion of pelvic vein incompetence and aged between 18 and 55 years were recruited prospectively over two years at a large UK University Teaching Hospital. Trans-vaginal ultrasound was performed using a standardised protocol which included assessment of the ovarian and internal iliac veins bilaterally in the supine and semi-standing position with provocative manoeuvres. Diagnostic readability and inter-observer variability was determined. Results Mean (range) age of 43 (23-51). Visibility of all four pelvic veins was better in the supine position compared with semi standing position (76% vs 64%). Pelvic vein incompetence was identified in 34 of 50 (68%) women in the supine position compared with 38 of 50 (76%) women in the semi-standing position. Pelvic vein incompetence was demonstrated in 35 of 50 (70%) women with Valsalva manoeuvre. Inter-observer variability was 0.84 (kappa, very good agreement, p = 0.001). Conclusion Trans-vaginal ultrasound is effective at demonstrating pelvic vein incompetence. All trans-vaginal ultrasound protocols should include assessment of pelvic veins in the supine and semi-standing position with Valsalva manoeuvre.

AB - Purpose The aim of this paper is to report our experience of type II endoleak treatment after endovascular aneurysm repair with intra-arterial injection of the embolizing liquid material, Onyx liquid embolic system. Methods From 2005 to 2012, we performed a retrospective review of 600 patients, who underwent endovascular repair of an abdominal aortic aneurysm. During this period, 18 patients were treated with Onyx for type II endoleaks. Principal findings The source of the endoleak was the internal iliac artery in seven cases, inferior mesenteric artery in seven cases and lumbar arteries in four cases. Immediate technical success was achieved in all patients and no endoleak from the treated vessel recurred. During a mean follow-up of 19 months, no major morbidity or mortality occurred, and one-year survival was 100%. Conclusions Treatment of type II endoleaks with Onyx is safe and effective over a significant time period.

AB - Biospecimen donation is key to the Precision Medicine Initiative, which pioneers a model for accelerating biomedical research through individualized care. Personalized medicine should be made available to medically underserved populations, including the large and growing US Hispanic population. We present results of a study of 140 Hispanic women who underwent a breast biopsy at a safety-net hospital and were randomly assigned to receive information and request for consent for biospecimen and data sharing by the patient's physician or a research assistant. Consent rates were high (97.1% and 92.9% in the physician and research assistant arms, respectively) and not different between groups (relative risk [RR] = 1.05, 95% confidence interval [CI] = 0.96 to 1.10). Consistent with a small but growing literature, we show that perceptions of Hispanics' unwillingness to participate in biospecimen sharing for research are not supported by data. Safety-net clinics and hospitals offer untapped possibilities for enhancing participation of underserved populations in the exciting Precision Medicine Initiative. PMID- 27688296 TI - Effects of metformin on hyperglycemia in an experimental model of tacrolimus- and sirolimus-induced diabetic rats. AB - BACKGROUND/AIMS: Metformin (MET) is a first-line drug for type 2 diabetes mellitus (DM); its effect on new-onset diabetes after transplantation caused by immunosuppressant therapy is unclear. We compared the effects of MET on DM caused by tacrolimus (TAC) or sirolimus (SRL). METHODS: DM was induced by injection of TAC (1.5 mg/kg) or SRL (0.3 mg/kg) for 2 weeks in rats, and MET (200 mg/kg) was injected for 2 more weeks. The effects of MET on DM caused by TAC or SRL were evaluated using an intraperitoneal glucose tolerance test (IPGTT) and by measuring plasma insulin concentration, islet size, and glucose-stimulated insulin secretion (GSIS). The effects of MET on the expression of adenosine monophosphate-activated protein kinase (AMPK), a pharmacological target of MET, were compared between TAC- and SRL-treated islets. RESULTS: IPGTT showed that both TAC and SRL induced hyperglycemia and reduced plasma insulin concentration compared with vehicle. These changes were reversed by addition of MET to SRL but not to TAC. Pancreatic islet cell size was decreased by TAC but not by SRL, but addition of MET did not affect pancreatic islet cell size in either group. MET significantly increased GSIS in SRL- but not in TAC-treated rats. AMPK expression was not affected by TAC but was significantly decreased in SRL-treated islets. Addition of MET restored AMPK expression in SRL-treated islets but not in TAC treated islets. CONCLUSIONS: MET has different effects on hyperglycemia caused by TAC and SRL. The discrepancy between these drugs is related to their different mechanisms causing DM. PMID- 27688297 TI - Estimating the Risk of Radiocontrast-Associated Nephropathy. AB - Estimates of the incidence of radiocontrast-associated nephropathy vary widely and suffer from misclassification of the cause of AKI and confounding. Using the Nationwide Inpatient Sample, we created multiple estimates of the risk of radiocontrast-associated nephropathy among adult patients hospitalized in the United States in 2009. First, we stratified patients according to the presence or absence of 12 relatively common diagnoses associated with AKI and evaluated the rate of AKI between strata. Next, we created a logistic regression model, controlling for comorbidity and acuity of illness, to estimate the risk of AKI associated with radiocontrast administration within each stratum. Finally, we performed an analysis stratified by the degree of preexisting comorbidity. In general, patients who received radiocontrast did not develop AKI at a clinically significant higher rate. Adjusted only for the complex survey design, patients to whom radiocontrast was and was not administered developed AKI at rates of 5.5% and 5.6%, respectively. After controlling for comorbidity and acuity of illness, radiocontrast administration associated with an odds ratio for AKI of 0.93 (95% confidence interval, 0.88 to 0.97). In conclusion, the risk of radiocontrast associated nephropathy may be overstated in the literature and overestimated by clinicians. More accurate AKI risk estimates may improve clinical decision-making when attempting to balance the potential benefits of radiocontrast-enhanced imaging and the risk of AKI. PMID- 27688299 TI - Effects of whole-body vibration on neuromuscular performance in individuals with spinal cord injury: a systematic review. AB - OBJECTIVE: To examine the effects of whole-body vibration on neuromuscular performance in people with spinal cord injury and evaluate the safe and effective vibration protocols. METHODS: PubMed, EMBASE, CINAHL and PEDro were mainly searched for English literatures. Other data sources were ClinicalTrials.gov , Current Controlled Trials and reference lists of all relevant articles. The PEDro scale was used to evaluate the methodological quality, and the Oxford Centre for Evidence-based Medicine level of evidence was used to assess the level of evidence. Basic information and whole-body vibration protocols were extracted by two independent researchers. Any disagreements were resolved by the third researcher. RESULTS: Of the eight included studies involving 94 individuals with spinal cord injury and 24 able-bodied participants, six of them reported beneficial effects of whole-body vibration on muscle activation and the other two on muscle spasticity. Based on the reviewed studies, an intermittent mode of whole-body vibration (frequency: 10-50 Hz; amplitude: 0.6-4 mm) is less likely to cause adverse events when applying to spinal cord injury subjects standing on platform (knees flexed at 10 degrees -40 degrees ). CONCLUSIONS: The strength of evidence is insufficient in supporting the benefits of whole-body vibration on neuromuscular performance in individuals with spinal cord injury. The intermittent vibration (frequency: 10-50 Hz; amplitude: 0.6-4 mm; knee flexion: 10 degrees -40 degrees ) may be the possible effective range and have good compliance.

AB - The aim of this study was to determine the influence of different packaging materials on meat quality during cold storage. Therefore pork loins (m. longissimus thoracis et lumborum) obtained from crossbred pigs (Polish Landrance x Duroc, n = 6) were stored at 2 C in modified atmosphere packs (80% O2, 20% CO2) in four types of trays, which differ in gas permeability. Physicochemical (headspace gas composition, pH, colour, drip loss, cooking loss, shear force, the basic composition and fatty acid profile) and microbiological ( Salmonella spp., Escherichia coli, Enterobacteriaceae, total aerobic plates count, total psychrotrophic bacteria count, the number of lactic acid bacteria, Pseudomonas spp., the general amount of yeast and mold) parameters were monitored for up to 12 days. At the end of the storage period no differences in most physicochemical properties of pork loin due to type of packaging were found, however trays with high gas permeability had the greatest impact on total aerobic plates count and Pseudomonas spp. growth. PMID- 27688298 TI - WNT5A-JNK regulation of vascular insulin resistance in human obesity. AB - Obesity is associated with the development of vascular insulin resistance; however, pathophysiological mechanisms are poorly understood. We sought to investigate the role of WNT5A-JNK in the regulation of insulin-mediated vasodilator responses in human adipose tissue arterioles prone to endothelial dysfunction. In 43 severely obese (BMI 44+/-11 kg/m2) and five metabolically normal non-obese (BMI 26+/-2 kg/m2) subjects, we isolated arterioles from subcutaneous and visceral fat during planned surgeries. Using videomicroscopy, we examined insulin-mediated, endothelium-dependent vasodilator responses and characterized adipose tissue gene and protein expression using real-time polymerase chain reaction and Western blot analyses. Immunofluorescence was used to quantify endothelial nitric oxide synthase (eNOS) phosphorylation. Insulin mediated vasodilation was markedly impaired in visceral compared to subcutaneous vessels from obese subjects (p<0.001), but preserved in non-obese individuals. Visceral adiposity was associated with increased JNK activation and elevated expression of WNT5A and its non-canonical receptors, which correlated negatively with insulin signaling. Pharmacological JNK antagonism with SP600125 markedly improved insulin-mediated vasodilation by sixfold (p<0.001), while endothelial cells exposed to recombinant WNT5A developed insulin resistance and impaired eNOS phosphorylation (p<0.05). We observed profound vascular insulin resistance in the visceral adipose tissue arterioles of obese subjects that was associated with up regulated WNT5A-JNK signaling and impaired endothelial eNOS activation. Pharmacological JNK antagonism markedly improved vascular endothelial function, and may represent a potential therapeutic target in obesity-related vascular disease. PMID- 27688301 TI - Characteristics of adult smokers presenting to a mind-body medicine clinic. AB - Mind-body interventions can improve vulnerabilities that underlie smoking behavior. The characteristics of smokers who use mind-body medicine have not been explored, preventing the development of targeted interventions. Patients ( N = 593) presenting to a mind-body medicine clinic completed self-report measures. Patients were 67 percent never smokers, 27 percent former smokers, and 6 percent current smokers. Current smokers were younger; more likely to be single, unemployed, or on disability; and report greater depression symptoms, greater pain, and lower social support ( ps < .05).Current smokers who use mind-body medicine have unique psychosocial needs that should be targeted in mind-body smoking cessation interventions.

AB - Objective: In this study, we compared the efficacy of a combination of PKC blocker St. John's Wort (SJW) and morphine in mice with painful antiretroviral (2,3-dideoxycitidine [ddC]) and chemotherapic (oxaliplatin) neuropathy. Methods: Morphine (1 and 5 mg/Kg i.p.), SJW (1 and 5 mg/Kg o.s.), or their combination was administered by systemic injection, and antinociception was determined by using the hot and cold plate tests. Results: Here we demonstrate the ability of SJW to relieve neuropathic pain in mice neuropathic models and a potentiation of morphine antinociception in thermal pain. The potentiating effect shown by SJW was not secondary to its antinociceptive activity as the increase of the morphine antinociceptive effect was produced at a dose (1mg/kg o.s.) devoid of any capability to modulate the pain threshold in neuropathic pain mice. Further examinations of the SJW main components revealed that hypericin was responsible for the potentiating properties whereas flavonoids were ineffective. Conclusions: These results show that SJW has notable antinociceptive activity for both neuropathic pain models and could be used in neuropathic pain relief alone or in combination with morphine. These data support the utility of combination SJW/opioid therapy in pain management for antinociceptive efficacy by enhancing opioid analgesia. PMID- 27688310 TI - Classical Conditioning Fails to Elicit Allodynia in an Experimental Study with Healthy Humans. AB - Objective: Associative learning has been proposed as a mechanism behind the persistence of pain after tissue healing. The simultaneous occurrence of nociceptive and non-nociceptive input during acute injury mimics the pairings thought to drive classical conditioning effects. However, empirical evidence for classically conditioned allodynia is lacking. We aimed to manipulate pain thresholds with a classical conditioning procedure that used non-nociceptive somatosensory stimuli as conditioned stimuli (CS) and nociceptive stimuli as unconditioned stimuli. We also explored the influence of gender, depression, anxiety, negative affect, and pain catastrophizing on the main manipulation. Design: Thirty-four healthy humans participated in a differential classical conditioning procedure that used vibrotactile stimulations at two different locations as CS. In an acquisition phase, CS+ was paired with painful thermal stimulation, and CS- with nonpainful thermal stimulation. Heat pain threshold was assessed during paired heat-CS trials before and after acquisition. A 2 (time: 1 and 2) x 2 (condition: CS+ and CS-) repeated-measures analysis of variance compared pain thresholds before and after acquisition. Exploratory analyses explored the influence of gender, depression, anxiety, negative affect, and pain catastrophizing. Postexperiment questions investigated participants' awareness of the contingencies employed. Results: The classical conditioning procedure did not alter pain thresholds. Exploratory analyses did not reveal any influence of individual differences. Thirty of the 34 participants were unaware of the contingencies between stimuli. Conclusions: The results of this study provide no evidence that allodynia can be induced in healthy humans using a classical conditioning procedure with simultaneous timing. PMID- 27688311 TI - Predictors of Persistent Disability and Back Pain in Older Adults with a New Episode of Care for Back Pain. AB - Objective: To identify predictors of persistent disability and back pain in older adults. Design: Prospective cohort study. Setting: Back pain outcomes using longitudinal data registry. Subjects: Five thousand two hundred twenty adults age 65 years and older with a new primary care visit for back pain. Methods: Baseline measurements included: demographics, health, and back pain characteristics. We abstracted imaging findings from 348 radiology reports. The primary outcomes were the Roland-Morris Disability Questionnaire (RMDQ) and back pain intensity. We defined persistent disability as RMDQ of 4/24 or higher at both six and 12 months and persistent back pain as pain 3/10 or higher at both six and 12 months. Results: There were 2,498 of 4,143 (60.3%) participants with persistent disability, and 2,099 of 4,144 (50.7%) had persistent back pain. Adjusted analyses showed the following characteristics most strongly predictive of persistent disability and persistent back pain: sex, race, worse baseline clinical characteristics of back pain, leg pain, back-related disability and duration of symptoms, smoking, anxiety symptoms, depressive symptoms, a history of falls, greater number of comorbidities, knee osteoarthritis, wide-spread pain syndromes, and an index diagnosis of lumbar spinal stenosis. Within the imaging data subset, central spinal stenosis was not associated with disability or pain. Conclusion: We found that many predictors in older adults were similar to those for younger populations. PMID- 27688312 TI - Pulsed Radiofrequency Attenuates Complete Freund's Adjuvant-Induced Epigenetic Suppression of Potassium Chloride Cotransporter 2 Expression. AB - Background: Pulsed radiofrequency (PRF) treatment offers pain relief for patients suffering from chronic pain who do not respond well to conventional treatments. We tested whether PRF treatment attenuated complete Freund's adjuvant (CFA) induced inflammatory pain. Epigenetic modification of potassium-chloride cotransporter 2 (KCC2) gene expression was examined to elucidate the potential contributing mechanism. Methods: Male Sprague-Dawley rats were injected with CFA into the plantar surface of the left hind paw to induce inflammation. PRF (20 minutes of 500-kHz RF pulses, delivered at a rate of 2 Hz, maximum temperature 42oC) was delivered to the L5 and L6 anterior primary ramus just distal to the intervertebral foramen of adult CFA or saline rats. The hind paw withdrawal threshold to von Frey filament stimuli and withdrawal latency to radiant heat were determined before and after CFA. Acetyl-histone H3 and H4 was determined by chromatin immunoprecipitation in spinal dorsal horn. KCC2 expression was determined by Western blot. Inhibitory synaptic function was evaluated by patch clamp in lamina II neurons. Results: KCC2 gene expression was suppressed through histone hypoacetylation, resulting in decreased efficacy of GABAergic signaling in CFA rats. PRF increased histone acetylation and KCC2 expression, partially restored the GABA synaptic function, and relieved sensitized pain behavior. Conclusion: These findings suggest that PRF might be an alternative therapy for inflammatory pain. One of the underlying mechanisms is through modification of KCC2, which is an important determinant for the efficacy of inhibitory neurotransmission in the spinal cord, and its expression levels are regulated by histone acetylation epigenetically following inflammation. PMID- 27688313 TI - Pain Treatments for Nursing Home Residents with Advanced Dementia and Substantial Impaired Communication: A Cross-Sectional Analysis at Baseline of a Cluster Randomized Controlled Trial. AB - Objectives: This is a cross-sectional analysis at baseline of a cluster randomized controlled trial to identify factors associated with the use of pharmacological and nonpharmacological pain treatments by nursing home residents with dementia and impaired communication. Methods: One hundred thirty-four residents with dementia and impaired communication were recruited. Nine of them were excluded because data on their pain treatments were missing, resulting in 125 for analysis. Hierarchical generalized estimating equations analyses controlling for the clustering effect of nursing homes were used to identify factors associated with the use of pharmacological and nonpharmacological pain treatments. Results: Although all participants had a confirmed pain condition, only 23 (18.4%) and 45 (36%) had received pharmacological or nonpharmacological pain treatments, respectively. Participants with a higher ability to communicate ( P = 0.031) and fewer pain locations were found to be more likely to receive pain medications, with the impact of communication ability being greater among participants with better cognitive status than among those with poor cognitive status. Participants who had been living in the home longer and who were more dependent were less likely to receive nonpharmacological treatments. Conclusion: Suboptimal pain management was common among this population. Severe impairment in the ability to communicate is a major reason for the underuse of pain medications. Staff may become desensitized and fail to perceive subtle changes in the residents' behavior as indicative of pain, leading to the underadministering of nonpharmacological treatments. To improve this situation, it is suggested that observational pain assessments be systematically carried out in nursing homes.

PMID- 27688314 TI - Genotype-Dependent and -Independent Calcium Signaling Dysregulation in Human Hypertrophic Cardiomyopathy. AB - BACKGROUND: Aberrant calcium signaling may contribute to arrhythmias and adverse remodeling in hypertrophic cardiomyopathy (HCM). Mutations in sarcomere genes may distinctly alter calcium handling pathways. METHODS: We analyzed gene expression, protein levels, and functional assays for calcium regulatory pathways in human HCM surgical samples with (n=25) and without (n=10) sarcomere mutations compared with control hearts (n=8). RESULTS: Gene expression and protein levels for calsequestrin, L-type calcium channel, sodium-calcium exchanger, phospholamban, calcineurin, and calcium/calmodulin-dependent protein kinase type II (CaMKII) were similar in HCM samples compared with controls. CaMKII protein abundance was increased only in sarcomere-mutation HCM (P<0.001). The CaMKII target pT17 phospholamban was 5.5-fold increased only in sarcomere-mutation HCM (P=0.01), as was autophosphorylated CaMKII (P<0.01), suggestive of constitutive activation. Calcineurin (PPP3CB) mRNA was not increased, nor was RCAN1 mRNA level, indicating a lack of calcineurin activation. Furthermore, myocyte enhancer factor 2 and nuclear factor of activated T cell transcription factor activity was not increased in HCM, suggesting that calcineurin pathway activation is not an upstream cause of increased CAMKII protein abundance or activation. SERCA2A mRNA transcript levels were reduced in HCM regardless of genotype, as was sarcoplasmic endoplasmic reticular calcium ATPase 2/phospholamban protein ratio (45% reduced; P=0.03). 45Ca sarcoplasmic endoplasmic reticular calcium ATPaseuptake assay showed reduced uptake velocity in HCM regardless of genotype (P=0.01). The cardiac ryanodine receptor was not altered in transcript, protein, or phosphorylated (pS2808, pS2814) protein abundance, and [3H]ryanodine binding was not different in HCM, consistent with no major modification of the ryanodine receptor. CONCLUSIONS: Human HCM demonstrates calcium mishandling through both genotype-specific and common pathways. Posttranslational activation of the CaMKII pathway is specific to sarcomere mutation-positive HCM, whereas sarcoplasmic endoplasmic reticular calcium ATPase 2 abundance and sarcoplasmic reticulum Ca uptake are depressed in both sarcomere mutation-positive and -negative HCM.

AB - The outcome of root canal treatment is based on efficient disinfection of the root canal system and prevention of reinfection. Current chemomechanical cleaning methods do not always achieve these goals, and insufficient root canal disinfection is the main reason for endodontic failure. Due to high energy content and specific characteristics of laser light, laser treatment has been proposed for cleaning and disinfecting the root canal system. This paper reviews the literature covering the effect of Er:YAG, Er,Cr:YSGG, Nd:YAG and diode laser on the root canal wall in the removal of smear layer and against intracanal bacteria. Recently, the use of laser energy to induce cavitation and acoustic streaming of intracanal irrigants has been investigated. Based on recent literature, it can be concluded that lasers have bactericidal effects. However, they still cannot replace sodium hypochlorite and should be considered as an adjunct to the current chemical root canal disinfection protocols. Certain lasers can help in removing the smear layer and debris and can modify the morphology of the root canal wall. Unfortunately, there have not been enough randomized clinical studies evaluating endodontic treatment outcome following the use of laser. PMID- 27688348 TI - Assessment of implant stability following sinus lift procedures with different grafting materials. AB - OBJECTIVE: The objective of this research was to evaluate implant stability following sinus lift with two grafting materials, and to compare it with the results obtained for the implants placed in a pristine posterior maxilla. MATERIALS AND METHODS: The study included 44 healthy patients with an existing indication for sinus lift procedure (test group). 46 implants were placed following sinus lift with a pure-phase beta-tricalcium phosphate, while 39 implants were placed following augmentation with 60% hydroxyapatite with 40% beta tricalcium phosphate material. The control group consisted of 48 healthy patients who were treated with 85 implants but without bone augmentation in posterior maxilla. Astra Tech OsseoSpeed implants were placed in all subjects. Resonance frequency analysis was used in both groups for determining implant stability 4 months after insertion. A mean implant stability quotient (ISQ) was calculated on the basis of 3 measurements. RESULTS: No statistical difference was observed in ISQ values of implants placed with and without augmentation procedure (p=0,789). Statistically significant difference was not found when ISQ values of implants placed following particular grafting material were compared with ISQ values of corresponding implants in a pristine bone (p=0.697 and p=0.402). CONCLUSIONS: This study demonstrated that the implant stability is comparable among implants placed in the posterior maxilla regardless of sinus lift and grafting procedure. Implants placed in the grafted posterior maxilla can be predictably loaded as the implants placed in a non-grafted, pristine maxilla. PMID- 27688347 TI - Effect of Endodontic Irrigating Solutions on the Micro Push-out Bond Strength of a Fibre Glass Dowel. AB - PURPOSE: To evaluate the effect of different endodontic irrigating solutions on the micro push-out bond strength of a fiber glass dowel. MATERIAL AND METHODS: Seventy 16-mm long root segments of bovine incisors were prepared and randomly assigned to 7 groups (n=10) according to the type of irrigating solution used prior to the cementation of the intra-radicular fiber glass dowels: G1: 5.25% NaOCl + 17% EDTA; G2: 5.25% NaOCl; G3: 17% EDTA; G4: 2% chlorhexidine gel; G5: 70% alcohol; G6: 11.5% polyacrylic acid; and G7: saline (control). After treatment of intracanal dentin, the glass fibre dowels were cemented with self adhesive resin cement (RelyX Unicem). Six slices with the thickness of 1.00 +/- 0.05 mm were obtained from each tooth at the coronal, middle and apical root thirds (2 slices per third) using a low-speed saw. Micro push-out tests were performed at a crosshead speed of 0.5mm/min and the data (MPa) were analyzed statistically by ANOVA and Tukey's and Dunnett's tests. RESULTS: There were statistically significant differences (p<0.0001) among the irrigating solutions, but no significant difference (p=0.0591) was found among the root thirds. G5 presented the highest bond strength mean of all groups (p<0.0001). The use of 70% alcohol increased the adhesion values by 53% compared to the group control. CONCLUSION: The use of 70% alcohol increased the bond strength of the fiber glass dowel to the dentin walls. However, the push-out bond strength between the dowel and the root dentin was not affected by the root third (coronal, middle and apical). PMID- 27688349 TI - Influence of Gender on the Patient's Assessment of Restorations on the Upper Anterior Teeth. AB - OBJECTIVE: The aim of this study was to assess the level of patients' satisfaction with appearance of maxillary anterior teeth restorations and to determine if there is a significant difference in patients' assessment of restoration appearance with regard to gender. MATERIALS AND METHODS: Two hundred subjects evaluated the colour, anatomical shape and surface texture of maxillary anterior teeth restorations (composite fillings, acrylic faceted metal crowns, porcelain-fused-to-metal crowns and all-ceramic crowns) in comparison with adjacent natural teeth. The data were expressed in patients' average assessment scores for colour, anatomical shape and surface texture as well as overall patients' average assessment scores for every type of restoration and overall patients' average assessment scores for colour, anatomical shape and surface texture of all the restorations in general. Patients also assessed the general impression of their maxillary anterior teeth restorations and rated it as satisfactory or unsatisfactory. RESULTS: There was a statistically significant gender difference in patient assessment of colour and surface texture for composite fillings and the overall patient average assessment score for colour of all assessments (p <0.05). Women were more dissatisfied with the general impression of their restorations on the upper teeth than men (p >0.05). Only overall patients' average assessment score for composite restorations almost reached the level of significance (p = 0.069) on patients' general impression. CONCLUSION: Colour of the restorations and the composite material are significant factors which affect dental appearance of maxillary anterior teeth in patients. PMID- 27688350 TI - The importance of a proper selection area to be biopsied in nodular leukoplakia: a case report. AB - Nodular leukoplakia is a non-homogeneous type of oral leukoplakia presenting a white surface with verrucous, nodular, ulcerated or erythematous features with a greater risk of malignant transformation when compared to the homogeneous type. Common sites of involvement include lip commissures, buccal mucosa and soft palate. It is often associated with epithelial dysplasia or carcinoma and requires detailed microscopic assessment and regular follow-up. The importance of a proper selection of the area to be biopsied and the close teamwork between a dentist and oral pathologist is the basis of providing an accurate final diagnosis. PMID- 27688352 TI - FORENSIC SCIENCE:: 20 YEARS OF FORENSIC DENTISTRY AT THE UNIVERSITY OF ZAGREB, 1994 - 2014. AB - Data from available literature point to an early beginning of Forensic Dentistry in Croatia relating to a post-mortem examination of a female patient after a dental procedure in the 1930s. Later on, there were several mass casualties due to collisions and airplane crashes and a railway accident at the Zagreb Main Railway Station wherein the identity of the victims was established based on dental features. Foreign experts in forensics helped identify those victims, particularly forensic dentists because this specialty was almost unknown in our region at the time. During the twenty-year period of the development of Forensic Dentistry at the University of Zagreb, the School of Dental Medicine, the city of Zagreb and Croatia have become internationally recognised on the forensic map of the world. PMID- 27688351 TI - Atypical Presentation of an Upper Lip Pleomorphic Adenoma: Case Report. AB - The pleomorphic adenoma (PA) or mixed tumor is the most common neoplasm of the salivary glands, usually presenting with a non-specific clinical manifestation and a diverse histopathological pattern. The region of the lips is the second most common site for minor gland neoplasms. The aim of this paper is to report the case of a 39 year old caucasian woman presenting with a swelling on the right side of the upper lip combined with a history of trauma in the region of the upper right central incisor, eight years ago. The swelling was attributed to the periapical lesion of the upper right central incisor that was observed on the orthopantomography. Intraoperatively the surgeon came upon a nodule of firm consistency in the mucolabial fold. The histopathologic diagnosis of this lesion was benign mixed tumor of salivary gland. This report discusses the deviation in frequency of mixed salivary gland tumor between upper and lower lip, the clinical differential diagnosis, the histopathological pattern and the appropriate treatment. PMID- 27688353 TI - Three-Dimensional Human Cell Cultures for Cytotoxicity Testing of Dental Filling Materials. AB - OBJECTIVES: So far, bovine immortalized pulp cells have been used as three dimensional cultures for cytotoxicity testing of filling materials in the dentin barrier test (DBT). In this study, the use of human pulp-derived cells was evaluated, which would better simulate the clinical situation, and a composite material with a new resin base was tested. MATERIALS AND METHODS: SV40 transfected human pulp cells (tHPC) were cultured in hydrogels (fibrin, peptide, collagen) and mechanical properties and cell viability (MTT or WST-1) were determined. For cell cultures in collagen, a four week - proliferation assay was performed (WST-1). After 14 days of three-dimensional culture in collagen, tHPC were introduced into the DBT with 200 um dentin disks. After a 24-hour incubation under perfusion (0.3 ml/h), the following materials were applied according to the manufacturers' instructions (1) President (Coltene): negative (non-toxic) control, (2) CaGPG14 (ISO 7405): positive (toxic) control, (3) Tetric EvoCeram (Ivoclar Vivadent) with Clearfil SEBond (Kuraray, reference material), (4) N'Durance (Sepodont, test material), (5) N'Durance with Clearfil SEBond. Cell viability was determined after 24-hour incubation (WST-1). The percentage of relative viability was calculated (negative control=100%) and statistically analyzed (Kruskal-Wallis-test, p<0.05). RESULTS: Fibrin and peptide gels had insufficient mechanical properties for the DBT Collagen and appeared suitable for three-dimensional cell culture of tHPC for up to 21 days. The cultures could be transferred to the DBT device and results for controls were similar to previous tests with bovine cells. The DBT using tHPC in the collagen showed no statistically significant difference between the test material with and without the adhesive and the reference resin composite. CONCLUSIONS: tHPC in collagen can replace bovine cells in the DBT. The tested filling material is not likely to cause pulp damage, if the pulp is covered by an intact dentin layer. PMID- 27688354 TI - CATASTROPHIZING IN PATIENTS WITH BURNING MOUTH SYNDROME. AB - BACKGROUND: Burning mouth syndrome (BMS) is an idiopathic painful condition which manifests with burning sensations in the oral cavity in patients with clinically normal oral mucosa and without any local and/or systemic causative factor. Catastrophizing is defined as an exaggerated negative orientation toward pain stimuli and pain experience. The aim of this study was to examine the association between catastrophizing and clinical parameters of BMS, and to examine the association between catastrophizing and the quality of life in patients with BMS. MATERIALS AND METHODS: Anonymous questionnaire consisting of 3 parts (demographic and clinical data with 100 mm visual analogue scale (VAS), Croatian version of the Oral Health Impact Profile (OHIP-14) scale and Croatian version of the Pain Catastrophizing scale (PC), was distributed to 30 patients diagnosed with BMS. RESULTS: A higher level of catastrophizing was clinically significant in 30% of the patients. Total catastrophizing score and all three subcomponents of catastrophizing significantly correlated with the intensity of symptoms, but did not correlate with the duration of symptoms. Gender and previous treatment did not affect the catastrophizing. CONCLUSION: Obtaining the information about catastrophizing could help a clinician to identify patients with negative behavioural patterns. Additional psychological intervention in these individuals could reduce/eliminate negative cognitive factors and improve coping with chronic painful condition such as BMS. PMID- 27688355 TI - Detection of Sulphate-Reducing Bacteria and Others Cultivable Facultative Bacteria in Dental Tissues. AB - AIM: To detect for the presence of sulphate-reducing bacteria (SRB) and evaluate the possible association between SRB and cultivable facultative bacterial of oral sites with different periodontal conditions. METHODS: The study was carried out on 9 samples from different oral sites in 8 patients (two samples were collected from the same patient). Material was collected using modified Postgate E culture medium, indicated for the growth and isolation of SRB. In addition, a reducing solution for anaerobic bacteria was used as a transport solution for facultative bacteria and identified by polymerase chain reaction amplification (PCR) and sequencing of the 16S rRNA gene. RESULTS: SRB was found in 3 patient samples: the first in a root fragment, the second in a root fragment and a healthy tooth with vertical bone loss and a mobility degree of 3; and the third in a healthy tooth extracted for orthodontic treatment. In the final patient, the cultivable facultative species Lactobacillus casei was identified. Other facultative bacterial species were identified in patient 5 (Kurthia Gibsonii) and patient 7 (Pseudomonas aeruginosa). CONCLUSIONS: The detection of SRB in different dental tissues with distinct periodontal features demonstrated that new studies need to be developed in order to determine the true role of SRB in the oral microbiota. In addition, it was possible to verify the presence of Lactobacillus casei together with SRB in one sample. PMID- 27688356 TI - A Comparative in Vitro Study of Apical Microleakage with Five Obturation Techniques: Lateral Condensation, Soft-Core(r), Obtura II(r), Guttaflow(r) and Resilon(r). AB - AIM: A comparison was made between the root canal lateral condensation technique and other condensation techniques in which physical (temperature: Soft-Core(r), Obtura II(r)) or chemical changes (condensation: Guttaflow(r), Resilon(r)) may affect the dimensional stability of obturation and thus favor apical microleakage. MATERIALS AND METHODS: A total of 212 single-root teeth removed for orthodontic or periodontal reasons were randomized to 5 groups of 40 teeth each. Six samples were used as positive controls, and another 6 as negative controls. The teeth were worked with the Hero 642 system, and each group was obturated using a different technique: lateral condensation, Obtura II(r), Soft-Core(r), Guttaflow(r) or Resilon(r). The samples were immersed in black ink, and after 72 hours the teeth were transparentized using the technique described by Robertson. Filtration of the ink was measured under the stereoscopic microscope. Analysis of variance and post-hoc testing were used for the statistical analysis. RESULTS: The Soft-Core(r) obturated group showed significantly greater microleakage than the other groups, with no differences among the rest of the groups. CONCLUSIONS: Under the conditions of this study, the teeth obturated with the Soft-Core(r) technique showed greater apical microleakage than the other systems. PMID- 27688357 TI - Apical Sealing Ability of a Novel Material: Analysis by Fluid Filtration Technique. AB - AIM: The aim of this study is to evaluate the sealing ability of Biodentine(TM), which is new calcium-silicate based dental cement and has endodontic indications similar to those of MTA. METHODS: The study sample consists of 21extracted human mandibular anterior teeth. The teeth were submitted to root-end preparation and instrumented up to file #40 by step back technique and randomly divided into 3 study groups (n=7): White MTA Angelus(TM) (Angelus, Angelus Odontologica, Londrina, PR, Brazil), Biodentine(TM) (Septodont, SeptodontSpecialites, Saint MaurdesFosses, France) and the controls. The length of dye penetration between the filling material and tooth structure was measured in millimetres, using a calibrated stereo microscope (Leica MZ75, Germany) at 20* magnification under the same conditions. One-way Analysis of Variance (ANOVA) was used to indicate differences between the experimental groups and the controls. In addition, Tukey Multiple Comparisons Test was used to indicate differences within each group. RESULTS: The results showed that none of the groups were completely sealed. The mean and standard deviation for dye penetration in Biodentine(TM) group was 0.63+/-0.20 and in MTA Angelus(TM) group, it was 0.26+/-0.25. Regarding the comparisons between each group, significant differences were not observed (P=0.0193). The comparison between materials only found a significant difference only between MTA Angelus(TM) and Biodentine(TM) (P<0.05). CONCLUSIONS: This study evaluated the possibility of Biodentine(TM)'s sealing ability and marginal adaptation, since no studies are available on Biodentine. However, further in vitro and in vivo investigations should be conducted to determine the suitability of Biodentine(TM) for clinical application. PMID- 27688358 TI - Attitude towards Oral Health at Various Colleges of the University of Zagreb: A Pilot Study. AB - PURPOSE: The aim of this study was to compare the oral status of three various groups of students: students of the School of Dental Medicine, students of technical sciences and students of humanities. MATERIAL AND METHODS: Research included 58 students of the University of Zagreb. They answered 3 questions: how often they brush their teeth, how often they visit their dentist and how important dental health is to them. After a standard dental check-up we calculated the DMFT index. They were given an indicator for plaque Mira-2-Ton(r) (Hager Werken, Duisburg, Germany) and we calculated the plaque index. For statistical analysis the ANOVA test was used. RESULTS: Students of the School of Dental Medicine had a lower plaque index than other students and this was statistically significant (p=0.0018; f=7.14). They also had a lower DMFT index, but it was not statistically significant (p=0.1004; f=2.4). 83% of students said that they brushed their teeth 2-3 times a day. Only 17% of all students brush their teeth more than 3 times a day and they are all students of the School of Dental Medicine (21% of them). Perception of oral health is on a high level, but perception of oral disease is not. The social approval of the answer was also an important factor. CONCLUSION: Students of the School of Dental Medicine are an illustrative example of improving our habits due to education. PMID- 27688359 TI - Dental Identification Through Endodontic Radiographic Records: a Case Report. AB - OBJECTIVE OF WORK: The present study aims to report a case of successful human identification based on the comparison of ante-mortem and post-mortem records of endodontic treatment. Based on these, the legal value of storing and updating clinical records is highlighted throughout the text. CASE REPORT: An unknown body was recovered from a traffic accident site. Forensic examination was conducted in order to establish the identity of the victim. Based on the absence of ante mortem fingerprint registration in the national database, the search for AM data was performed using periapical radiographic records from private dental clinics. A positive dental identification was achieved analyzing evidence of endodontic treatment. CONCLUSION: Dental radiographs play a valuable role as legal tools supporting the criminal demands on the daily forensic practice. Specifically in endodontics, periapical radiographs are essential for a proper treatment. In forensics, these radiographs represent a solid source of ante-mortem data for human identifications. PMID- 27688360 TI - Egg Freezing in Childhood and Young Adult Cancer Survivors. AB - Fertility preservation in prepubertal and young adolescent girls scheduled for chemotherapy is a demanding situation. Despite the recent impressive improvements of ovarian cortex cryopreservation, significant limitations persist. The technique remains experimental, it exposes the girl to the risks of surgery and to an iatrogenic insult to the ovarian reserve, and there is no guarantee of use because not all girls will undergo re-implantation. Moreover, it is impossible to respect all the requested conditions for a valid informed consent. The girl is minor, the time for decision is very short, and the prospect of not surviving clouds both the girl and her relatives. An alternative but neglected option is oocyte cryopreservation after the end of cancer treatments, when the girl reaches adulthood. This possibility can overcome some of the limitations of ovarian cortex freezing and may be considered for girls scheduled for a chemotherapy at low or medium risk of ovarian reserve impairment. In this case report, we describe the case of a young female patient with cancer who survived 2 chemotherapies for 2 distinct cancers and who was diagnosed with reduced ovarian reserve. The patient underwent 3 cycles of ovarian hyperstimulation and ultimately stored 19 oocytes. The success obtained in this girl suggests consideration of egg freezing as an alternative fertility-preservation procedure in prepubertal and young adolescent girls scheduled for chemotherapy. However, cryopreservation of ovarian tissue remains the only option for those scheduled for chemotherapies at high risk of ovarian reserve impairment. PMID- 27688361 TI - Safety of Oral Propranolol for the Treatment of Infantile Hemangioma: A Systematic Review. AB - BACKGROUND AND OBJECTIVES: Given the widespread use of propranolol in infantile hemangioma (IH) it was considered essential to perform a systematic review of its safety. The objectives of this review were to evaluate the safety profile of oral propranolol in the treatment of IH. METHODS: We searched Embase and Medline databases (2007-July 2014) and unpublished data from the manufacturer of Hemangiol/Hemangeol (marketed pediatric formulation of oral propranolol; Pierre Fabre Dermatologie, Lavaur, France). Selected studies included >=10 patients treated with oral propranolol for IH and that either reported >=1 adverse event or effect (AE) or planned to capture AEs. Data capture was standardized and extracted study design, demographic characteristics, IH characteristics, intervention, and safety outcomes. AEs were assigned a system organ class and preferred term. RESULTS: A total of 83 of 398 identified literature records met the inclusion criteria, covering 3766 propranolol-treated patients. The manufacturer's data for 3 pooled clinical trials (435 propranolol-treated patients) and 1 Compassionate Use Program (1661 patients) were included. AE data were reported for 1945 of 5862 propranolol-treated patients. The most frequently reported AEs included a range of sleep disturbances, peripheral coldness, and agitation. The most serious AEs (atrioventricular block, bradycardia, hypotension, bronchospasm/bronchial hyperreactivity, and hypoglycemia-related seizures) were managed by decreasing doses or temporary/permanent discontinuation of propranolol. Limitations included the variety of included study designs; monitoring, collection, and reporting of AE data; small sample sizes for some articles; and the wide scope of review. CONCLUSIONS: Oral propranolol is well tolerated if appropriate pretreatment assessments and within-treatment monitoring are performed to exclude patients with contraindications and to minimize serious side effects during treatment.

AB - Modern documents, scientific articles and books are primarily issued in electronic form and their availability depends on the publisher's, or the document owner's, business ethics. The primary purpose of publishing a scientific article is to communicate with the scientific and professional community; therefore, the published article has to be available worldwide. The question is: Who really needs scientific papers from the 1960's? In cases of brilliant and bold visionaries, new concepts and scientific discoveries often come before their time; hence they have to be "reinvented" decades later. Besides, the scientists of today can enter the spiritual spheres of their professional ancestors and give respect to their legacy.?We have processed more than 1 200 articles published by 1999 and entered more than?6 000 names and surnames of authors. PMID- 27688364 TI - Factors Affecting Oral Health-Related Quality of Life Among Elderly Croatian Patients. AB - OBJECTIVE OF WORK: Oral health-related quality of life (OHRQoL) as a multidimensional concept is affected by many factors. Therefore, the aim of this study was to determine which demographic and subjective factors are significantly affecting the OHRQoL among the elderly people wearing complete removable dental prostheses (CRDP). MATERIALS AND METHODS: This questionnaire-based study included 301 participants, residents of elderly care homes (in Zagreb and Slavonski Brod, Croatia) wearing maxillary and/or mandibular CRDP. The questionnaire used in this study consisted of two sections; the first section included questions giving general information and in the second section the Croatian version of Oral Health Impact Profile (OHIP)-49 questionnaire with 49 items representing seven OHIP domains was used. RESULTS: Participants were aged between 60-99 years, with average age of 74 +/- 12.1 years. OHIP summary score was 26.5. The highest average OHIP mean values in the domain of functional limitation amounted to 6.7, physical pain 5.1, and physical disability 5.9. The participants' age, education, profession, residence place size, type of CRDP, and the time of denture wearing period all statistically significantly affected OHRQoL (p < 0.05). CONCLUSIONS: General and sociodemographic factors had a significant influence on the participant's subjective perception of oral health and OHRQoL. Younger participants, participants from rural places, those with lower levels of education, and shorter period of denture wearing demonstrated a higher impact on OHRQoL. PMID- 27688362 TI - Predicting Severe Pneumonia Outcomes in Children. AB - BACKGROUND: Substantial morbidity and excessive care variation are seen with pediatric pneumonia. Accurate risk-stratification tools to guide clinical decision-making are needed. METHODS: We developed risk models to predict severe pneumonia outcomes in children (<18 years) by using data from the Etiology of Pneumonia in the Community Study, a prospective study of community-acquired pneumonia hospitalizations conducted in 3 US cities from January 2010 to June 2012. In-hospital outcomes were organized into an ordinal severity scale encompassing severe (mechanical ventilation, shock, or death), moderate (intensive care admission only), and mild (non-intensive care hospitalization) outcomes. Twenty predictors, including patient, laboratory, and radiographic characteristics at presentation, were evaluated in 3 models: a full model included all 20 predictors, a reduced model included 10 predictors based on expert consensus, and an electronic health record (EHR) model included 9 predictors typically available as structured data within comprehensive EHRs. Ordinal regression was used for model development. Predictive accuracy was estimated by using discrimination (concordance index). RESULTS: Among the 2319 included children, 21% had a moderate or severe outcome (14% moderate, 7% severe). Each of the models accurately identified risk for moderate or severe pneumonia (concordance index across models 0.78-0.81). Age, vital signs, chest indrawing, and radiologic infiltrate pattern were the strongest predictors of severity. The reduced and EHR models retained most of the strongest predictors and performed as well as the full model. CONCLUSIONS: We created 3 risk models that accurately estimate risk for severe pneumonia in children. Their use holds the potential to improve care and outcomes. PMID- 27688365 TI - Idiopathic Osteosclerosis of the Jaw in a Brazilian Population: a Retrospective Study. AB - OBJECTIVES: To report cases of idiopathic osteosclerosis (IO), to review the literature on the subject, and to discuss its main characteristics, diagnosis, differential diagnosis, and treatment. MATERIAL AND METHODS: Retrospective analysis of 354 panoramic radiographs, searching for IO, its size, shape, location, and noting patients' demographic information. Literature review used Medline and Lilacs databases and the terms idiopathic osteosclerosis OR bone sclerosis OR dense bone island AND jaws. RESULTS: IO was identified in 5.6% of the radiographs (n=20 patients, 22 foci). Patients were healthy, with an age ranging from 5 to 51 years (mean=29.8), with male-female ratio of 3:2. IOs were found mainly in the premolar/molar region, at root apices, between roots, away from the teeth, laterally to the tooth, and in edentulous areas. The distribution between right and left sides of the jaw was equal for the 22 foci, with only one case in the maxilla. IOs were localized, well-defined, radiopaque, mostly round or ovoid in shape, but sometimes irregular. In some cases, IOs were similar to condensing osteitis, but differential diagnosis also considered complex odontoma, focal cemento-osseous dysplasia, and residual roots. Twenty studies on the topic were reviewed. CONCLUSIONS: Incidence of IO in the Brazilian sample was 5.6%, with age ranging from 5 to 51 years (mean=29.8), and male-female ratio of 3:2. The radiopacities occurred in different locations, with significant prevalence in the mandible. The findings and the literature review corroborate the hypothesis that IO should be considered developmental variation of normal bone that does not require treatment. PMID- 27688366 TI - Use of Pre-Injection Diffusion of Local Anaesthetic as a Means of Reducing Needle Penetration Discomfort. AB - AIM: To determine if pre-injection diffusion of local anaesthetic solution influences the discomfort of needle penetration in the palate. METHODS: A placebo controlled, randomised, double-blind split-mouth investigation was conducted. 25 healthy adult volunteers were recruited and each received two needle penetrations in a random order during one visit. The penetration sites were 1 cm from the gingival margin of the first maxillary premolars on each side of the mouth. 30 gauge-13 mm needles which were attached to syringes that contained either 2% lidocaine with 0.125mg/ml epinephrine or physiological saline were used. For each penetration an operator encouraged a drop of solution to appear at the end of the needle and placed this drop with the bevel of the needle flat on the palate for 20 seconds. The discomfort was noted on a 100 mm visual analogue scale with end points marked "No pain" and "Unbearable pain". RESULTS: There was no significant difference in penetration discomfort between solutions, (mean VAS = 26.80+/ 19.36mm for lidocaine and 26.20+/-18.39mm for saline) however the 2nd penetration was significantly more uncomfortable than the first (mean VAS = 31.00+/-19.84 mm and 22.00+/-16.65 mm respectively). CONCLUSION: Pre-injection diffusion of local anaesthetic solution did not influence the discomfort of needle penetration in the palate. PMID- 27688367 TI - A Survey of Removable Partial Denture (RPD) Retentive Elements in Relation to the Type of Edentulism and Abutment Teeth Found in Commercial Laboratories, Athens, Greece. AB - OBJECTIVE: The aim of this survey was to record removable partial denture (RPD) retentive elements and abutment teeth in partially edentulous patients, identified in commercial laboratories in Athens, Greece. MATERIAL AND METHODS: 628 master casts with the corresponding cast metal frameworks used in the construction of RPDs were evaluated. Casts were photographed to identify the number and position of existing teeth, the partial edentulism class and the retentive elements. Prevalence tables and the x(2) test were used for the statistical analysis of the collected data (alpha=.05). RESULTS: There were 276 maxillary (43.9%) and 352 (56.1%) mandibular casts. Maxillary edentulism entailed almost a total absence of right third molars in 96.7% and left third molars 96.0% of casts, with lower rates for the first and second molars. Edentulism in the posterior mandible presented a similar pattern. The most profound findings concerning retentive elements were: 91.9% of the retainers used were clasps and the remaining 8.1% were attachments. Of the clasps used, 48.9% were of the Roach Tau type, a finding more common in Kennedy Class I as compared to other Kennedy Classes (p<0.01). The circumferential clasps accounted for 19.3% of the total clasps used, and it was less frequently presented (8.8%) in Kennedy I Classes (p<0.01). CONCLUSIONS: Roach clasps were used in the majority of cases whereas RPI clasps and attachments were rarely used. PMID- 27688368 TI - A Fast Method for DEFB1 - 44C/G SNP Genotyping in Brazilian Patients with Periodontitis. AB - AIM: Defensins are cationic antimicrobial peptides expressed in epithelial cells. Such peptides exhibit antibacterial, antifungal and antiviral properties, and are a component of the innate immune response. It has been suggested that they have a protective role in the oral cavity. This study evaluated the DEFB1 polymorphism in diabetic patients with or without periodontitis in comparison to healthy controls. MATERIAL AND METHODS: We used Hairpin-Shaped Primer (HP) assay to study the distribution of the -44 C/G SNP (rs1800972) in 119 human DNAs obtained from diabetic patients and healthy control patients. RESULTS: The results indicate that there are no differences in distribution between groups and that in diabetic periodontitis patients the homozygous mutant could be found more frequently. CONCLUSION: Further studies are necessary in order to investigate the role of DEFB1 polymorphisms in diabetic periodontitis patients and the influence of the peptide in periodontal pathogens. PMID- 27688369 TI - Endodontic Management of the Three-Rooted Mandibular First Permanent Molar: a Case Report. AB - The distal root of the mandibular first permanent molar (MFPM) contains one or two canals. More rarely, the second/third distal canal is found in a separate root in a distolingual (DL) position - a radix entomolaris (RE). In Caucasians, this occurs in less than 4% of cases, but it is equally important to be aware of this possibility. Careful examination of the preoperative periapical radiographs (orthoradial and mesially angled) and inspection of the pulp chamber floor during endodontic management may indicate that this radicular variant is present. RE's lingual inclination and buccolingual curvature must be taken into account during cleaning and shaping of the canal within this root to avoid procedural errors, such as straightening and ledging of the root canal, perforation or instrument fracture. The aim of the present paper was to discuss a case report of a young patient, referred to an endodontic office after a ledge was created by inappropriate instrumentation of a buccolingually curved RE canal. PMID- 27688370 TI - Topical Steroids and CO2 Laser in the Treatment of Refractory Oral Lichenoid Drug Reaction and Lichenoid Contact Lesion: a Case Report. AB - A 54-year-old female presented with severe pain on the gingiva and buccal mucosa. Oral findings revealed generalized fiery red gingiva, ulcerative with white striae covered by pseudo-membranes on both buccal mucosae. She had hypertension, dyslipidemia, subclinical hypothyroidism and arthritis. She was treated with atorvastatin, hydrochlorothiazide, valsartan, levothyroxine and non-steroidal anti-inflammatory drug (NSAIDs). Her oral lesions were a slight improvement from a previous treatment with pimecrolimus cream, triamcinolone acetonide 0.1% orabase and injection. After diclofenac was replaced with tenoxicam and oral lesions were treated with various topical steroids, the lesions showed marked improvement. The biopsy from the buccal mucosa revealed oral lichen planus. Patch test showed positivity to mercury, gold sodium thiosulfate and palladium. One year later the left buccal mucosa showed red, round papillomatous-like lesions. The histopathological report showed a non-specific ulcer with chronic inflammation. The lesions flared up after replacing amalgam with crowns. After CO2 laser treatment, the lesions showed some improvement. Direct and indirect immunofluorescence of the lesions proved to be negative. This first case report showed that the palliative treatment of refractory oral lichenoid lesions with potent topical steroids for 7 years had no side-effects. CO2 laser can be an alternative treatment of refractory lesion in this case. PMID- 27688371 TI - Gingival necrosis due to the ill-fitting denture. AB - We present a case of an 80-year-old male who was referred to the Department of Oral Medicine, School of Dental Medicine University of Zagreb, Croatia due to gingival ulcer which was present for eight days. Clinical examination has revealed exposed bone on the toothless alveolar ridge in the lower molar region on the right side of 0.8 cm in diameter. Otherwise, the patient was taking doxazosin due to urinary problems and ipatropium bromide due to respiratory problems. The patient wore a 6-year-old partial lower denture. He was initially treated with periodontal bandage (Resopack, HagenWerken, Germany) for the first three days and was instructed not to wear the denture; however, no benefit could be seen. Therefore, we added a local corticosteroid (betamethasone) and am oral antiseptic (chlorhexidine digluconate) applied three times a day. After 3 weeks the lesion healed. A list of possible causative factors regarding gingival ulcers is included. PMID- 27688372 TI - 50(th) Anniversary of the Central Dental Library of School of Dental Medicine University of Zagreb. AB - Libraries have an exceptional place in the history, culture, education and scientific life of a nation. They collect all aspects of our linguistics and literacy, all out theoretical assumptions as well as all the results of experience and practice. The importance of a library is not mirrored only in the national and historical role and heritage, but in a more permanent, informational role, since a modern library must, above all, be an effective information system. Since a library of a university operates as a part of its matrix, it is easily shadowed by other forms of educational and scientific infrastructure. 50(th) anniversary of the Central Dental Library of the School of Dental Medicine University of Zagreb is an excellent opportunity to make a call to the institution and public to its unique and irreplaceable role. PMID- 27688373 TI - Alveolar Bone Grafting in Cleft Patients from Bone Defect to Dental Implants. AB - Cleft lip and palate is the most common congenital deformity affecting craniofacial structures. Orofacial clefts have great impact on the quality of life which includes aesthetics, function, psychological impact, dental development and facial growth. Incomplete fusion of facial prominences during the fourth to tenth week of gestation is the main cause. Cleft gaps are closed with alveolar bone grafts in surgical procedure called osteoplasty. Autogenic bone is taken from the iliac crest as the gold standard. The time of grafting can be divided into two stages: primary and secondary. The alveolar defect is usually reconstructured between 7 and 11 years and is often related to the development of the maxillary canine root. After successful osteoplasty, cleft defect is closed but there is still a lack of tooth. The space closure with orthodontic treatment has 50-75% success. If the orthodontic treatment is not possible, in order to replace the missing tooth there are three possibilities: adhesive bridgework, tooth transplantation and implants. Dental implant has the role of holding dental prosthesis, prevents pronounced bone atrophy and loads the augmentation material in the cleft area. Despite the fact that autologous bone from iliac crest is the gold standard, it is not a perfect source for reconstruction of the alveolar cleft. Bone morphogenic protein (BMP) is appropriate as an alternative graft material. The purpose of this review is to explain morphology of cleft defects, historical perspective, surgical techniques and possibilities of implant and prosthodontic rehabilitation. PMID- 27688374 TI - The Level of Anxiety and Pain Perception of Endodontic Patients. AB - OBJECTIVES: to compare the level of anxiety reported by patients and assessed by dentists. Also, the expected and actual pain during the treatment perceived by the patient and dentist were assessed. METHODS: sixty six endodontic patients filled in two questionnaires, prior to and after the treatment, so did their therapists. The first set of questions for patients was regarding demographics, the frequency of dental visits, the level of anxiety and expectations about the level of pain. Before the treatment, dentists estimated the level of patients' anxiety and the expected intensity of pain. After the treatment, the patients evaluated the level of experienced pain and dentists' empathy during the treatment, while dentists reassessed the intensity of patients' pain.The data were statistically analysed by t-test for paired samples and by Spearmans's Rho correlation coefficient at level of significance set at 0.05. RESULTS: Patients' expectation of pain intensity was higher than the actual pain during the treatment (t-test=3.540, p=0.001). There was no difference in the level of pain which dentists expected and their perception of pain during the procedure. There was a statistically significant correlation between the patients' level of anxiety and recognition of it by dentists (Spearman Rho=0.460, p<0.001). A higher level of anxiety increased the expected intensity of pain (Spearman Rho=0.401, p=0.001). Actual intensity of pain was not significantly associated with dental anxiety (Spearman Rho=0.080, p=0.524). CONCLUSION: Since the level of dental anxiety was associated with the increased intensity of expected pain, a vicious cycle of pain and anxiety may be terminated by giving positive information to the patient before and during endodontic procedures. PMID- 27688375 TI - Atmospheric Pressure Plasma Jet as an Accelerator of Tooth Bleaching. AB - OBJECTIVE: To study the effect of atmospheric pressure plasma (APP) jet as a potential accelerator of the degradation of hydrogen peroxide in bleaching gels which could lead to better and faster bleaching. MATERIAL AND METHODS: 25 pastilles of hydroxylapatite were colored in green tea for 8 hours and were randomly divided into five groups (n = 5). The bleaching process was performed with 30% and 40% hydrogen peroxide (HP) gel alone and in conjunction with helium APP jet. During the bleaching treatment, optical emission spectroscopy and non contact surface temperature measurement using pyrometer were performed. Color of the pastilles was determined by a red-green-blue (RGB) colorimeter. PH values of bleaching gels were measured before and after the plasma treatment on additional 10 pastilles using a pH meter with contact pH electrode. RESULTS: The color measurements of pastilles before and after the treatment showed that treatment with APP jet improved the bleaching effect by 32% and 15% in the case of 30% and 40% HP gel. Better results were obtained approximately six times faster than with a procedure suggested by the bleaching gel manufacturer. Optical emission spectroscopy proved that plasma has a chemically active role on the gel. After the APP treatment, pH values of bleaching gels dropped to about 50-75% of their initial value while the surface temperature increased by 8-10C above baseline. CONCLUSION: The use of plasma jet provides more effective bleaching results in a shorter period of time without a significant temperature increase which may cause damage of the surrounding tissue. PMID- 27688376 TI - The Effect of Repeated Microwaving Disinfection on the Dimensional Stability of Acrylic Dentures. AB - OBJECTIVE: The aim of this study was to evaluate the effect of repeated microwave disinfections on the dimensional stability of acrylic dentures. MATERIALS AND METHODS: Three groups of dentures made of a heat polymerized acrylic resin were tested. I: dentures kept in water (control group). II: dentures microwaved daily while being immersed into water (wet disinfection). III: dentures microwaved daily without being immersed into water (dry disinfection).?Measurements were taken across three reference points, on two occasions: after curing and immersion in water for 24 hours, and one week later.?Data obtained were analyzed using one way analysis of variance (ANOVA) and Scheffe's multiple range test. RESULTS: The results showed that the microwave disinfection provokes dimensional changes of the same pattern (shrinkage). The dentures which underwent wet disinfection exhibited the greatest shrinkage (p<0.05). CONCLUSIONS: Disinfection using microwave energy may cause dimensional changes (shrinkage) of complete dentures.?The microwave "dry disinfection" method can be safely applied in everyday practice since the dimensional changes which occurred seem to be of no clinical significance. PMID- 27688377 TI - Effects of Wire EDM on the Microstructure of P/M Titanium Samples. AB - PURPOSE: Commercially pure titanium (CP Ti) has been recognized in dentistry for its biocompatibility, good mechanical properties and corrosion resistance. Conventional manufacturing processes can affect surface quality and result in poor bonding of dental ceramics to CP Ti. This is why powder metallurgy (P/M) and wire electro-discharge machining (WEDM) are being introduced in the manufacturing process. The aim of this study was to evaluate the effect of WEDM on the surface composition and microstructure of P/M CP Ti samples produced for bond strength testing according to ISO 9693. MATERIALS AND METHODS: Eight samples of P/M CP Ti, dimensions according to ISO 9693, were made using WEDM and divided in two groups (untreated and grinded). Microanalyses of chemical composition and microstructure of both groups were made using SEM, EDS and XDR. RESULTS: SEM and EDS analysis of untreated samples showed a thin layer on surfaces with fractures in it. Grinded samples showed homogenous structure with no layer and no fractures. XDR analysis showed high level of oxides on the surface of untreated samples, while after grinding only pure alpha-phase was found. CONCLUSION: WEDM is a suitable method of sample production for ISO 9693 if accompanied by grinding with silicon carbide papers P320-P4000. PMID- 27688378 TI - Histochemistry and Immunohistochemistry Evaluation of the Abrikossoff's Tumour of the Tongue: a Case Report. AB - Abrikossoff's tumour is a rare benign soft tissue neoplasm that can occur in any part of the body, including the orofacial region. The tumour is usually benign, but there are reports of cases in which the tumour shows a locally aggressive behaviour, malignancy, and distant metastases. The aetiology is unknown, since several studies have shown that different cells are involved. In the present case, a 36-year-old Dominican woman was referred to the Department of Oral and Maxillofacial Surgery in Policlinico Federico II, Naples with a circumscribed lesion and sessile nodule on the dorsum of the tongue measuring about 17 mm in diameter. The treatment consisted of an excisional biopsy performed on the basis of the diagnostic hypothesis of Abrikossoff's tumour, which was confirmed by histopathological analysis and histochemistry and immunohistochemistry evaluation. Abrikossoff's tumour is an uncommon neoplasm which must be carefully diagnosed considering all the histological and clinical aspects in order to be treated correctly. PMID- 27688379 TI - Epidermoid Cyst Arising in the Buccal Mucosa: Case Report and Literature Review. AB - Epidermoid cysts are benign subcutaneous lesions, and the large majority of these cysts affect the floor of the mouth; however, the buccal mucosa is not the usual site of occurrence. To date, only 5 articles have been published with 6 cases of epidermoid cysts arising in the buccal mucosa. Therefore, the aim of this study was to describe the clinical, histopathological and immunohistochemical features of a case of an epidermoid cyst located in the buccal mucosa. To our knowledge, this is the first report of an oral epidermoid cyst describing an intense foreign body gigantocellular inflammatory reaction against epithelial keratin component. Although the usual diagnosis for epidermoid cysts is based on histopathological findings, this case report addresses novel information regarding the immunohistochemical pattern which may be found in these lesions. PMID- 27688380 TI - Dental Ritual Mutilations and Forensic Odontologist Practice: a Review of the Literature. AB - BACKGROUND: Ethnic mutilations have a social and anthropological significance both in contemporary and past human behavior, influenced by geographic, religious and cultural factors which can greatly help forensic odontologist's practice in dental profiling process.?Dental ritual mutilations and dental decorations were - and still are - practiced among many ethnic groups and cultures. Throughout the history of humanity, having healthy teeth has a symbolic meaning of youth, beauty and strength, but it can also have other meanings.?Dental ritual mutilations were documented in many cultures in the past and were practiced mainly for religious rituals purposes, for esthetic reasons and because they represented a symbol of status or of belonging to a particular social group. Similar rituals are still performed. MATERIAL AND METHOD: The present paper is a systematic review of the literature reporting on dental ritual mutilations from the early 1960s and is included in Pubmed, Scopus and Googlescholar. The research was deliberately limited only to the ritual mutilations, which can be defined as "any irreversible impairment of the integrity of the human organism, made with a ritual purpose and without any curative aim". Therefore all the articles dealing with single or multiple dental self extractions of psychotic origins were excluded, as well as the infant oral mutilations, since the practice is deemed to have therapeutical effects among ethnic groups dedited to this practice. CONCLUSIONS: The knowledge of dental alteration due to oral mutilations can be a powerful tool for the identification procedures of living or dead persons or even in human remains especially providing relevant information about the ethnic origins and the cultural background of a subject. Some medical legal issues for the odontologist about dental mutilation are also addressed in the paper. PMID- 27688381 TI - Periodontal Disease and its Association with Angiographically Verified Coronary Artery Disease. AB - PURPOSE: The aim of this research was to investigate the association of chronic and aggressive periodontitis with the severity of coronary artery disease which was angiographically verified. MATERIAL AND METHODS: Subjects were selected among the hospitalized patients at the University Hospital Centre Zagreb who had coronary angiography done because of the chest pain. Thorough clinical examination included periodontal indices and clinical and socio-demographic characteristics of participants. Subjects were divided in two test groups, acute coronary syndrome (ACS) and stable coronary artery disease (CAD), and the control group with no significant CAD. Data were analyzed using Kruskal-Wallis and Pearson's Chi-Square test. RESULTS: From 106 subjects, 66 (62.3%) were hospitalized for ACS, 22 (20.7%) had stable CAD and only 18 (17.0%) had no significant CAD. Only 26 (24.5%) out of 106 patients were never smokers (p<0.05). Chronic periodontitis was the most common finding with 68.2% in ACS group and 54.5% in stable CAD group, while healthy patients without periodontitis (72.6%) were dominant in the control group (p<0.001). Stable CAD group had the highest mean probing depth (PD) 3.92+/-1.16, gingival recession (GR) 1.34+/-0.78, clinical attachment level (CAL) 4.60+/-1.41 and bleeding on probing (BOP) 45.98+/ 26.19 values, whereas ACS group had mean PD value of 3.77+/-0.91, GR 1.11+/-0.66, CAL 4.32+/-1.08 and BOP 41.30+/-22.09, and no significant CAD group had mean PD value of 3.27+/-0.97, GR 0.69+/-0.37, CAL 3.62+/-1.04 and BOP 26.39+/-13.92 (p<0.05). CONCLUSION: Periodontitis was shown to be associated with angiographically verified coronary artery disease. Physical inactivity, poor oral hygiene and periodontal inflammation were observed in patients with ACS and stable CAD. PMID- 27688382 TI - A Quantitative Analysis of a Probiotic Storage Media for Avulsed Teeth. AB - AIM: The aim of the present in vitro study was to investigate the potential of a storage medium, probiotic yogurt (Bifidibacterium animalis DN 173010) in comparison with Hank's balanced salt solution (HBSS), saline and milk in maintaining viable periodontal ligament (PDL) cells on simulated avulsed teeth. MATERIALS AND METHODS: Thirty-six freshly extracted single-rooted human teeth with closed apices were divided into six experimental groups (N=6). The teeth were extracted as atraumatically as possible and washed in sterile saline solution to eliminate residual blood. Following extractions, the coronal 3 mm of PDL tissues were scraped with a #15 scalpel to remove cells that may have been damaged. The positive and negative controls corresponded to 0 minutes and an 8 hour dry time, respectively. After extraction, the positive control teeth were immediately treated with dispase and collagenase. The negative control teeth were bench-dried for 8 h, with no follow-up storage solution time, and then placed in the dispase and collagenase. The number of viable protective least significant difference PDL cells were counted under a light microscope with a hemocytometer at 20* magnification and analyzed. Statistical analysis of the data was accomplished using Nonparametric ANOVA complemented by Kruskal-Wallis Test and Dunn's Multiple Comparisons Test. RESULTS: Positive control was found to be significantly better than the others, there were statistically significant differences between positive control and other test groups (p=0.000). The teeth stored in positive control demonstrated the highest number of viable PDL cells followed in order by probiotic yogurt, HBSS, saline and milk. CONCLUSION: Bifidibacterium animalis DN 173010 seems to be an alternative for the temporary storage of avulsed teeth, due to high number of viable PDL cells. Probiotics may be suitable transport media for avulsed teeth, but further research is warranted using the commercially available products. PMID- 27688383 TI - Analysis of Translucency Parameter of Glass-Ceramics Fabricated by Different Techniques. AB - THE PURPOSE: of the study was to analyse translucency parameter (TP values) of glass-ceramics fabricated by different techniques and investigate the effect of the corrosive medium on TP values. MATERIALS AND METHODS: Three specimens of each type of IPS e.max ceramics (Ivoclar Vivadent, Schaan, Liechtenstein) were made in three colours (A2, C2 and B3) by three fabrication techniques (layering - e.max Ceram Dentin; heat-pressing - e.max Press; CAD/CAM - e.max CAD). Specimens were made in the form of plates (10 mm x 12 mm x 0.8 mm). CIE L*a*b* values were measured by a spectrophotometer (X-Rite DTP 20 Pulse, Neu Isenburg, Germany) before and after exposure to 4% acetic acid at 80 degrees C for 16 hours (ISO 6872) to calculate translucency parameter (TP values). Statistical data were analysed using the IBM SPSS 22 software. RESULTS: IPS e.max Ceram Dentin had significantly the lowest TP values, and IPS e.max Press the highest TP values of all colours (A2, C2, B3), both prior and after exposure to acid (p<0.001). The difference in TP values among colours was evident in the IPS e.max Ceram Dentin material, both before and after exposure to acid with a great effect size (p<0.001; eta2 = 0.702 and 0.741), and in the IPS e.max Press material (p<0.001, effect size 0.547 and 0.576). CAD/CAD specimens showed uniform TP values between three colours. Further, exposure to a corrosive medium did not result in a statistically significant change of TP values in any of the materials tested. CONCLUSIONS: Different types of glass-ceramics showed significant difference in TP values both with respect to the fabrication technique and colour. Exposure to a corrosive medium did not result in a statistically significant change of TP values. PMID- 27688384 TI - Influence of the Hinge Axis Transfer Modality on the Three-Dimensional Condylar Shift Between the Centric Relation and the Maximum Intercuspation Positions. AB - PURPOSE: The purpose of the study was to determine whether the hinge axis registration and the transfer modality (facebow transfer vs. average mounting) from the subject to the articulator affect the three-dimensional condylar shift between the centric relation (CR) and the maximum intercuspation (MI) position. MATERIAL AND METHODS: The study was comprised of 32 fully dentate subjects (16 male and 16 female). Only the asymptomatic participants with normal occlusal relations (Angle class I) aged 20 - 33 (mean age 22.6 +/- 4.7) met the inclusion criteria. Three-dimensional condylar shift (anteroposterior, superoinferior and mediolateral shift) between the centric relation position (CR) and the maximum intercuspation (MI) position was analyzed by means of Mandibular Position Indicator (SAM Prazisionstechnik GmbH, Muenchen, Germany). RESULTS: The average three-dimensional condylar shift was 0.13 +/- 0.12 mm for facebow transfer and 0.22 +/- 0.23 mm for average mounting. There were no statistically significant differences noted between genders. The results of the Mann-Whitney test showed statistically significant differences for anteroposterior and superoinferior condylar shift (P < 0.001). However, the difference in the mediolateral shift was not statistically significant. CONCLUSIONS: In order to find discrepancies within the three-dimensional condylar shift, facebow transfer proved to be more accurate than the average mounting in the semi-adjustable articulator. However, the average value of three-dimensional shifts of the condyle did not differ from normal values and they did not have clinical significance. Thus, both ways of transfer modalities (facebow transfer and average mounting) in asymptomatic subjects with normal occlusion can be considered reliable. PMID- 27688386 TI - Posttraumatic Stress Disorder and Orofacial Pain. AB - Chronic orofacial pain occurs frequently in patients with posttraumatic stress disorder (PTSD) and at the same time any pathological process involving orofacial area can be reflected in emotional interpretation of pain and can trigger a series of reactions associated with the PTSD group of symptoms in patients with PTSD. Painful stimuli caused in this way may occur after the primary cause ceased, and because of convergence can cause referred pain outside of the anatomical site where the primary injury occurred. Chronic orofacial pain and PTSD are diagnosed on the basis of subjective testimony and this regularly occurs in the context of social interaction between patients, doctors, medical staff or researchers making it difficult to standardize the results and introduces many cultural phenomena. PMID- 27688385 TI - Functional Impressions in Complete Denture and Overdenture Treatment. AB - Tooth loss can cause loss of occlusal, masticatory, esthetic, physiognomic, phonetic and psychosocial function of patients. The most frequently used treatment method of completely edentulous patients and patients with a small number of remaining teeth are complete dentures or overdentures. One of the most important clinical and laboratory procedures in their fabrication is functional impression taking. The aim of this paper was to present procedures of taking functional impressions in fabrication of complete dentures and overdentures, using standardized techniques and materials. An accurate functional impression together with other correctly performed clinical and laboratory procedures ensure good retention and stability of dentures, which is a precondition for restoring patients' lost functions. PMID- 27688387 TI - Craniofacial Fibrous Dysplasia in an Elderly Patient: A Case Report with a Review of Literature. AB - Fibrous dysplasia is a benign fibro-osseous disorder, characterized by fibrous connective tissue containing abnormal bone which replaces normal bone. It represents 2 to 5% of all bone tumors and 7% of all benign tumors. Most commonly it affects younger age groups, with a higher prevalence in the maxilla than the mandible. It is a lesion of unknown etiology, uncertain pathogenesis, and diverse histopathology. Fibrous dysplasia can involve multiple bones (polyostotic) or a single bone (monostotic). The lesions of fibrous dysplasia can be surgically recontoured for esthetic or functional purposes once the growth ceases. Here we report a case of craniofacial fibrous dysplasia in an 83-year-old elderly male patient with emphasis on radiographic features.

PMID- 27688390 TI - Presentation of Certain Parameters Found In 2009-2013 Annual Dental Medicine Reports. AB - The Croatian Institute of Public Health (CIPH) collects health care related statistical data based on the Republic of Croatia's Annual Plan of Implementation of Statistical Activities. The purpose of this study was to analyse the CIPH data retrieved from annual reports, obtained from contractual teams and institutions related to dental medicine activities, collected in respective counties and for the entire country. MATERIAL AND METHODS: The data were collected from the Croatian Statistical Health Care Yearbook for the period from 2009 to 2013. RESULTS: The analysis has shown the increase in the number of insured persons (5%), but the decrease in the number of persons who received care (10%) and the increase in the number of visits (14%) and general examinations (13%). The majority of the beneficiaries were from the City of Zagreb with the highest number of visits, but with a low number of general examinations included in these visits (11%); while the Zadar County had the highest number of general examinations in terms of dental health care users (90.6%) and the proportion of general examinations in visits (30%). The most common diagnosis was dental caries (43%). The incomplete and insufficient reporting from some counties, inadequate recording of diagnoses and of curative and preventive procedures could be the factors affecting the quantity and quality of obtained data. Proper and regular submissions of reports to counties' public health institutes, regular preventive examinations, adequate recording of diagnoses and procedures would contribute positively to further health planning and the implementation of preventive measures for the improvement of oral health. CONCLUSION: The data analysis gives an insight into the current situation allowing on such basis further planning and conducting of activities at national and local level. Further analyses would help to get a better perspective and improvement of dental medicine activities. PMID- 27688391 TI - The Oral Status of Adult Population in the Croatian Town of Knin: a Cross Sectional Study. AB - THE AIM: Epidemiologic studies in many countries show uneven distribution of oral diseases (primarily caries) within the population. This is why more studies are oriented towards specific regions or subpopulations instead of large scale national surveys. The major purpose of this cross sectional study was to obtain relevant data about the oral status of the population of Knin and its surroundings according to the WHO criteria. SUBJECTS AND METHODS: The study included 414 participants aged between 18 and 65. The recorded variables included general anamnestic data, extraoral status, oral mucosa status, temporomandibular joint status, dental, periodontal and prosthetic status, and the need for dental restoration. The comparison between different groups regarding age, gender, educational level and origin was made. RESULTS: DMFT index was 17.3 - with on average 1.7 caries, 6.2 fillings, and 9.4 teeth extracted. SiC index equaled 26.4. The difference was significant regarding the level of education and age (p<0.001). The percentages of individuals with the highest CPI scores from 0-4 were 27.3, 16.9, 36.5, 16.4 and 2.9%, respectively. The difference between the age groups in CPI scores was statistically significant, while the differences according to the gender and origin were not significant (p=0.001). CONCLUSION: The population of Knin and the surrounding area exhibited very bad oral status which can be attributed to the consequences of the war in the 1990-ies, the economic transition, and the lack of national program for oral health promotion. PMID- 27688392 TI - Antimicrobial Capacity of Casein Phosphopeptide/Amorphous Calcium Phosphate and Enzymes in Glass Ionomer Cement in Dentin Carious Lesions. AB - OBJECTIVE: To evaluate the ability of casein phosphopeptide/amorphous calcium phosphate (CPP/ACP) and lysozyme, lactoferrin, and lactoperoxidase (LLL) added to glass ionomer cement (GIC) to inhibit the growth of S. mutans in a caries model. MATERIAL AND METHODS: Eighty permanent third molars were selected. The dentin of these teeth was exposed and flattened. Except for the coronal dentin, the specimens were waterproofed, autoclaved, and submitted to cariogenic challenge with standard strain of S. mutans. The carious lesions were sealed as follows: group 1 (n=20): GIC without additives; group 2 (n=20): GIC + CPP/ACP; group 3 (n=20): GIC + LLL; group 4 (n=20): GIC + CPP/ACP + LLL. S. mutans counts were performed before the caries were sealed (n=5), after 24 hours (n=5), at 1 month (n=5), and at 6 months (n=5). The results were analyzed using descriptive statistical analysis and the Kruskal-Wallis test (Student-Newman-Keuls test). RESULTS: GIC + LLL caused a significant reduction of S. mutans 1 month after sealing (p<0.01); however, there was a significant growth of S. mutans 6 months after sealing. GIC, GIC + CPP/ACP, and GIC + CPP/ACP + LLL showed similar behavior with significant reduction of S. mutans after 24 hours (p<0.05) and increase after 1 and 6 months. CONCLUSION: The addition of LLL to GIC increases the antimicrobial action of GIC on S. mutans. This leads to control of bacterial biofilm for 1 month, thus stopping the progression of carious lesions.

AB - OBJECTIVES: The objective of this study was to evaluate the intra-device repeatability and accuracy of dental shade-matching device (VITA Easyshade(r) Advance 4.0) using both in vitro and in vivo models. MATERIALS AND METHODS: For the repeatability assessment, the in vivo model utilized shade-matching device to measure the central region of the labial surface of right maxillary central incisors of 10 people twice. The following tooth colors were measured: B1, A1, A2, A3, C1 and C3. The in vitro model included the same six Vitapan Classical tabs. Two measurements were made of the central region of each shade tab. For the accuracy assessment, each shade tab from 3 Vitapan Classical shade guides was measured once. CIE L*a*b* values were determined. Intraclass correlation coefficients (ICCs) were used to analyze the in vitro and in vivo intra-device repeatability of the shade-matching device. The difference between in vitro and in vivo models was analyzed. Accuracy of the device tested was calculated. RESULTS: The mean color differences for in vivo and in vitro models were 3.51 and 1.25 E units, respectively. The device repeatability ICCs for in vivo measurements ranged from 0.858 to 0.971 and for in vitro from 0.992 to 0.994. Accuracy of the device tested was 93.75%. CONCLUSION: Within the limitations of the experiment, VITA Easyshade(r)Advance 4.0 dental shade-matching device enabled reliable and accurate measurement. It can be a valuable tool for the determination of tooth colours. PMID- 27688394 TI - Mandibular Range of Movement and Pain Intensity in Patients with Anterior Disc Displacement without Reduction. AB - OBJECTIVE: Temporomandibular disorders (TMD) are the most common source of orofacial pain of a non-dental origin. The study was performed to investigate the therapeutic effect of the conventional occlusal splint therapy and the physical therapy. The hypothesis tested was that the simultaneous use of occlusal splint and physical therapy is an effective method for treatment of anterior disc displacement without reduction. MATERIALS AND METHODS: Twelve patients (mean age =30.5 y) with anterior disc displacement without reduction (according to RDC/TMD and confirmed by magnetic resonance imaging) were randomly allocated into 2 groups: 6 received stabilization splint (SS) and 6 received both physical therapy and stabilization splint (SS&PT). Treatment outcomes included pain-free opening (MCO), maximum assisted opening (MAO), path of mouth opening and pain as reported on visual analogue scale (VAS). RESULTS: At baseline of treatment there were no significant differences among the groups for VAS scores, as well as for the range of mandibular movement. VAS scores improved significantly over time for the SS&PT group (F=28.964, p=0.0001, effect size =0.853) and SS group (F=8.794, p=0.001, effect size =0.638). The range of mouth opening improved significantly only in the SS&PT group (MCO: F=20.971, p=0.006; MAO: F=24.014, p=0.004) (Figure 2). Changes in path of mouth opening differ significantly between the groups (p=0.040). Only 1 patient in SS&PT group still presented deviations in mouth opening after completed therapy while in the SS group deviations were present in 5 patients after completed therapy. CONCLUSION: This limited study gave evidence that during the treatment period lasting for 6 months, the simultaneous use of stabilization splint and physical therapy was more efficient in reducing deviations and improving range of mouth opening than the stabilization splint used alone. Both treatment options were efficient in reducing pain in patients with anterior disc displacement without reduction. Despite of objectively diagnosed disruption of temporomandibular joint anatomy, physiological function was regained.

AB - PURPOSE: The aim of the study was to analyze the amount of maxillary and mandibular crestal bone loss around Bredent Sky Blue type of implants of different dimensions one year after implantation. MATERIALS AND METHODS: 36 implants of diameter 3.5 x 10 mm were inserted in the maxilla and 12 in the mandible. 52 implants of diameter 4.0 x 8 mm were inserted in the maxilla, and 61 in the mandible (two-stage implant surgery). RESULTS: No statistically significant differences were found between the right and left side of the maxilla and between the right and left side of the mandible at the implant sites regarding distal and mesial bone losses as shown by analysis of variance (ANOVA). CONCLUSION: Statistically significant differences were found between anterior maxilla, posterior maxilla and anterior mandible and posterior mandible at implant sites regarding distal and mesial bone losses as shown by analysis of variance (ANOVA). PMID- 27688397 TI - A Fixed Telescopic Prosthesis Designed to Retrieve and Convert to Fixed-Removable Combination Case: A Clinical Report. AB - This clinical report describes a fixed maxillary telescopic dental prosthesis (FTDP) employing milled base metal copings and a metal superstructure veneered with composite resin, for the restoration in a periodontally compromised patient with uncontrolled diabetes. The telescopic prosthesis framework design incorporated occlusal rest seats in key positions along the arch in case of future posterior tooth loss, in order to be converted to fixed - removable combination prosthesis. The mandible was restored with a conventional fixed ceramo-metal dental prosthesis. PMID- 27688396 TI - New Knowledge about Zirconium-Ceramic as a Structural Material in Fixed Prosthodontics. AB - Dental ceramics represents a major structural material in fixed prosthodontics. Increasing demands for esthetics led to development of new ceramic materials in order to eliminate the use of metal framework and for all ceramic restorations with mechanical properties to withstand high occlusal forces. Out of all the present ceramic materials, zirconium-ceramic has the best mechanical properties, and is the only material that can be used for longer span fixed dental restorations. Despite its excellent mechanical properties, to achieve great esthetics, due to absence of translucency, zirconium-dioxide cannot be used as a single material and needs veneering with more esthetic ceramic. When introduced in dental medicine, it was considered an almost ideal material for fixed prosthodontics, but clinical use and in vivo and in vitro studies showed many problems which still persist despite the improvements.?This review aims to reveal new developments in zirconium-ceramics and technical procedures which could increase clinical performance and longevity of these restorations. PMID- 27688398 TI - Severe Generalized Periodontitis in a Patient with an Aplastic Anemia: a 5 Year Follow-up Case Report. AB - Aplastic anemia is a hematological disorder characterized by pancytopenia. This case report presents a young patient with untreated periodontitis associated with hematological disorders, and cyclosporine therapy. During 2 consecutive days, periodontal therapy which consisted of nonsurgical therapy supplemented with an antibiotic treatment and antifibrinolytic therapy was performed. Commercial microbiological PCR tests and periodontitis IL-1 polymorphism risk test were performed. Following the periodontal therapy, the inflammation was resolved and the patient's occlusion was restored by means of removable partial dentures. After the 5 year follow-up, the patient still remained with shallow probing depths although there was inadequate compliance during the maintenance phase. Aplastic anemia increases the risk of onset of severe forms of periodontitis that can be additionally complicated with cyclosporine therapy. In such patients, periodontal therapy must be supplemented with antibiotics. PMID- 27688399 TI - Cystic Shape Cemento-Ossifying Fibroma of Ethmoid Sinus. AB - Cemento-ossifying fibromas are a group of rarely occurring benign tumours, developing from the periodontal membrane and varying considerably in appearance and in the progress of the disease. Their common feature is higher or lower production of cemental tissue. In most cases the tumours are small because their cementoma mature quickly and become inactive, which causes the tumour to stop growing. They develop most frequently in the mandible and also in the maxilla. Other sites, such as paranasal cavities, soft tissues and bones of the head, are extremely rare. The case of a cemento-fibrosing tumour with psammoma infiltrations, developing from the ethmoid sinus in a nine-year-old girl is reported. Due to frontal headaches and sight defects as well as impaired vision on the right side, NMR was done, which showed a mucocele of the front and rear ethmoid with destruction of the orbital wall and a breakthrough into the orbit. The right maxillary sinus showed a visible retention and a thickened mucous membrane. A rhinoscopy revealed a ball-shaped spherical mass in the medial nasal meatus, which was defined as concha bullosa. An endoscopic examination showed that the tumour protruded in front of the medium nasal concha into the right nasal cavity, softened the ethmoid roof, penetrated toward the base of the skull, adhered and pushed the orbit. It was removed by FESS technique, and PHD revealed subsequently that it was not a mucocele but a cemento-ossifying fibroma. PMID- 27688400 TI - Neuron type-specific miRNA represses two broadly expressed genes to modulate an avoidance behavior in C. elegans. AB - Two broad gene classes are distinguished within multicellular organisms: cell type-specific genes, which confer particular cellular properties, and ubiquitous genes that support general cellular functions. However, certain so-called ubiquitous genes show functionally relevant cell type-specific repression. How such repression is achieved is poorly understood. MicroRNAs (miRNAs) are repressors, many of which are expressed with high cell type specificity. Here we show that mir-791, expressed exclusively in the CO2-sensing neurons in Caenorhabditis elegans, represses two otherwise broadly expressed genes. This repression is necessary for normal neuronal function and behavior of the animals toward CO2 miRNA-mediated repression of broadly transcribed genes is a previously unappreciated strategy for cellular specialization. PMID- 27688403 TI - In Vitro Evaluation and Comparison of the Translucency of Two Different All Ceramic Systems. AB - OBJECTIVES: The aim of this study was to evaluate and compare the translucency of two different all-ceramic systems using Vita Easyshade digital shade matching device in an in vitro model. MATERIALS AND METHODS: Translucency of lithium disilicate glass-ceramic (IPS e.max Press) and zirconia all-ceramic system (Ceramill ZI) were evaluated and compared. A total of 5 square-shaped specimens with 0.5 mm thickness were fabricated from each ceramic system in A1 shade according to Vitapan Classical shade tab. Specimens were then veneered and glazed with corresponding veneer ceramics recommended by each system manufacturer and the total thickness was set to 1.5 mm. Translucency was evaluated using VITA Easyshade in two stages: before and after veneering and glazing on black and white background. Translucency parameter (TP) was calculated. A one-way ANOVA and Bonferonni tests were used when appropriate (alpha=0.05). RESULTS: Lithium disilicate glass-ceramic was significantly more translucent than the zirconia system in both stages (P<0.05). Translucency of all specimens was significantly decreased after veneering and glazing in both all-ceramic systems (P<0.05). CONCLUSION: The translucency of two different dental ceramics was significantly influenced by both material and stages of preparation. Within the limitations of the experiment, these results can be valuable and help the clinician to make appropriate esthetic decisions. PMID- 27688402 TI - E2F coregulates an essential HSF developmental program that is distinct from the heat-shock response. AB - Heat-shock factor (HSF) is the master transcriptional regulator of the heat-shock response (HSR) and is essential for stress resilience. HSF is also required for metazoan development; however, its function and regulation in this process are poorly understood. Here, we characterize the genomic distribution and transcriptional activity of Caenorhabditis elegans HSF-1 during larval development and show that the developmental HSF-1 transcriptional program is distinct from the HSR. HSF-1 developmental activation requires binding of E2F/DP to a GC-rich motif that facilitates HSF-1 binding to a heat-shock element (HSE) that is degenerate from the consensus HSE sequence and adjacent to the E2F binding site at promoters. In contrast, induction of the HSR is independent of these promoter elements or E2F/DP and instead requires a distinct set of tandem canonical HSEs. Together, E2F and HSF-1 directly regulate a gene network, including a specific subset of chaperones, to promote protein biogenesis and anabolic metabolism, which are essential in development. PMID- 27688404 TI - The Oral Cavity State in Renal Transplant Recipients. AB - AIM: Patients with a solid organ transplant can have many different complications in the mouth, as a result of immunosuppression and side effects of drugs. The aim of this study was to examine the frequency and type of oral lesions in renal transplant patients, dental status, oral hygiene, oral lesions related to drugs which patients take and the time of transplantation as well as the frequency of patient's visits to the dentist in the post-transplant period. MATERIAL AND METHODS: The study was performed in a period of two years and included 100 subjects with a renal transplant during their regular control visits to the Department of Nephrology and Dialysis, Clinical Hospital Centre Zagreb and the Department of Oral Medicine, School of Dental Medicine, University of Zagreb and 100 randomly selected control subjects at the Department of Endodontics and Restorative Dentistry, School of Dental Medicine, University of Zagreb. RESULTS: Results showed a significantly higher incidence of oral lesions in patients with renal transplant (31%) compared to control subjects. The most frequent were erythematous (inflammatory changes), keratotic lesions and gingival hyperplasia. The average DMFT index was significantly lower in patients with renal transplant than in the control group. One third of patients had a subjective feeling of dry mouth. Oral hygiene was poor overall, and only a small number of subjects used the additional sustainers for oral hygiene. Most patients did not visit the dentist after the transplantation. CONCLUSION: Renal transplant patients need a comprehensive and regular dental care during the pre- and post-transplant period and a doctor of dental medicine should be part of a multidisciplinary team of medical specialists. PMID- 27688401 TI - Functional interplay between Mediator and TFIIB in preinitiation complex assembly in relation to promoter architecture. AB - Mediator is a large coregulator complex conserved from yeast to humans and involved in many human diseases, including cancers. Together with general transcription factors, it stimulates preinitiation complex (PIC) formation and activates RNA polymerase II (Pol II) transcription. In this study, we analyzed how Mediator acts in PIC assembly using in vivo, in vitro, and in silico approaches. We revealed an essential function of the Mediator middle module exerted through its Med10 subunit, implicating a key interaction between Mediator and TFIIB. We showed that this Mediator-TFIIB link has a global role on PIC assembly genome-wide. Moreover, the amplitude of Mediator's effect on PIC formation is gene-dependent and is related to the promoter architecture in terms of TATA elements, nucleosome occupancy, and dynamics. This study thus provides mechanistic insights into the coordinated function of Mediator and TFIIB in PIC assembly in different chromatin contexts. PMID- 27688405 TI - Folate and Vitamin B12 Levels in Thai Patients with Oral Lichenoid Related Drug. AB - BACKGROUND: Medications have been increasingly used by patients for the treatment of their systemic diseases. However, many drugs are reported to induce oral lichenoid lesions (OLL). AIM: The aim of our study was to investigate the relationship between OLL, medications, and folate and vitamin B12 levels. MATERIAL AND METHODS: Twenty Thai patients who were diagnosed with OLL by clinical and histopathological examination were included in this study. These subjects were compared with 24 healthy control subjects. Complete blood counts, hemoglobin typing, serum and red cell folate, and serum vitamin B12 levels were investigated. The medications taken and the systemic diseases of the Thai patients with OLL were recorded and analyzed. RESULTS: Our results showed that only 1/20 patients with OLL (5%) had low red cell folate and only 1 case showed a low level of serum folate. Vitamin B12 levels were within normal range in both groups. There were no significant differences in red cell folate, serum folate, or vitamin B12 levels between the patients with OLL and the control group (p>0.05). Four cases in OLL and 3 cases in the control group had low hematocrit less than 36% and they were defined as anemic. CONCLUSION: Antihypertensives and hypolipidemics were the most common medications taken by patients with OLL; however, these drugs had no effect on red cell folate, serum folate, or vitamin B12 levels. Since the patients were taking multiple drugs and we could not confirm the diagnosis of OLDR by withdrawal of the drugs, we used the term OLL related drug instead. PMID- 27688406 TI - The Effect of Salivary Calcium and Fluoride Toothpaste on the Formation of KOH Soluble Fluoride: In Vitro Study. AB - OBJECTIVE: The aim of this in vitro preliminary study was to assess the effect of smokers' saliva (assuming their higher calcium concentration) in combination with fluoridated toothpaste on the enamel uptake of alkali-soluble (KOH-soluble) fluoride. MATERIALS AND METHODS: Four enamel slabs were cut from each of 14 impacted third molars and randomly assigned into 4 groups. Unstimulated saliva samples were collected from two age and sex matched volunteers. One of the samples was taken from a heavy smoker and the other sample was taken from a non smoker. Two groups (A and B) were shaken in saliva (A in smoker's saliva, B in nonsmoker's saliva) for 5 min and then shaken for 3 min in a toothpaste/deionized water slurry (1:3 w/w). One of the groups (group C) received no saliva treatment and was only shaken in toothpaste slurry for 3 min. The treatment was repeated after a 6-hour period. One of the groups (D) served as a control group with no treatment. RESULTS: Calcium concentration in the smoker's saliva was higher than in the nonsmoker's saliva. The enamel uptake of KOH-soluble fluoride in group A was significantly higher than that in the other two treatment groups, B and C. The enamel uptake of KOH-soluble fluoride in all 3 groups was statistically different from that in the control group. CONCLUSION: These results demonstrate that saliva collected from a heavy smoker, which had higher salivary calcium concentration, enhances enamel uptake of alkali-soluble fluoride and encourages us to conduct a large-scale study. PMID- 27688407 TI - Measurements of Implant Stability Following Sinus Lift: A Pilot Clinical Study. AB - AIM: The aim of this study was to evaluate the implant stability of Bredent Sky Blue implants of different diameters following one stage sinus lift procedure. MATERIAL AND METHODS: This study included 9 male patients with an existing indication for unilateral or bilateral sinus lift procedure. As grafting materials, combination of allograft material MinerOss(r) cortical & cancellous and Ossceram nano were used. RESULTS: All implants were considered successful and ISQ levels were measured by Osstell ISQ device. The ISQ values were from 68 to 84. The mean values of stability of Bredent Sky Blue implants of different diameters following one stage sinus lift procedure were 77.73 +/- 2.93 (MD) and 77.98 +/- 2.72 (VO). PMID- 27688408 TI - Quorum Sensing of Periodontal Pathogens. AB - The term 'quorum sensing' describes intercellular bacterial communication which regulates bacterial gene expression according to population cell density. Bacteria produce and secrete small molecules, named autoinducers, into the intercellular space. The concentration of these molecules increases as a function of population cell density. Once the concentration of the stimulatory threshold is reached, alteration in gene expression occurs. Gram-positive and Gram-negative bacteria possess different types of quorum sensing systems. Canonical LuxI/R type/acyl homoserine lactone mediated quorum sensing system is the best studied quorum sensing circuit and is described in Gram-negative bacteria which employ it for inter-species communication mostly. Gram-positive bacteria possess a peptide mediated quorum sensing system. Bacteria can communicate within their own species (intra-species) but also between species (inter-species), for which they employ an autoinducer-2 quorum sensing system which is called the universal language of the bacteria. Periodontal pathogenic bacteria possess AI-2 quorum sensing systems. It is known that they use it for regulation of biofilm formation, iron uptake, stress response and virulence factor expression. A better understanding of bacterial communication mechanisms will allow the targeting of quorum sensing with quorum sensing inhibitors to prevent and control disease. PMID- 27688410 TI - Influence of Adhesives and Methods of Enamel Pretreatment on the Shear Bond Strength of Orthodontic Brackets. AB - AIM: The objective of present study was to examine influence of adhesives and methods of enamel pretreatment on the shear bond strength (SBS) of orthodontic brackets. The adhesives used were resin-reinforced glass ionomer cements-GIC (Fuji Ortho LC) and composite resin (Transbond XT). MATERIAL AND METHODS: The experimental sample consisted of 80 extracted human first premolars. The sample was divided into four equal groups, and the metal brackets were bonded with different enamel pretreatments by using two adhesives: group A-10% polyacrylic acid; Fuji Ortho LC, group B-37% phosphoric acid; Fuji Ortho LC, group C-self etching primer; Transbond XT, group D-37% phosphoric acid, primer; Transbond XT. SBS of brackets was measured. After debonding of brackets, the adhesive remnant index (ARI) was evaluated. RESULTS: After the statistical analysis of the collected data was performed (ANOVA; Sheffe post-hoc test), the results showed that significantly lower SBS of the group B was found in relation to the groups C (p=0.031) and D (p=0.026). The results of ARI were similar in all testing groups and it was not possible to determine any statistically significant difference of the ARI (Chi- square test) between all four experimental groups. CONCLUSION: The conclusion is that the use of composite resins material with appropriate enamel pretreatment according to manufacturer's recommendation is the "gold standard" for brackets bonding for fixed orthodontic appliances. PMID- 27688409 TI - The Effect of Microwave Disinfection on Denture Base Polymers, Liners and Teeth: A Basic Overview. AB - The aim of this paper was to overview the current scientific knowledge concerning the effect of microwave disinfection on denture related material properties. Cross-infection control in dentistry is a significant issue in everyday clinical practice due to the recent increase in some infectious diseases such as hepatitis B, C and AIDS and therefore numerous methods of disinfection have been used. The most widespread method of disinfection used in everyday practice is chemical, however, studies have suggested that chemical disinfectants alter the physical and mechanical properties of the acrylic resins and enable the growth and proliferation of certain bacteria. Therefore, microwaves were introduced as an easy to use-and-access, low cost, chemical free alternative. The question that arose was if and in what way the microwave irradiation affected the denture related material properties. Microwaving affects the denture resin bases, liners and teeth in different ways. The results showed that microwave disinfection could be a safe alternative for the disinfection of denture bases and liners compared to the chemical one, when the procedure is carried out in dry conditions, but could possibly cause dimensional changes of clinical significance on them when the irradiation takes place in wet environment. It also seems to have no detrimental effects of clinical importance on the flexural properties, impact strength and hardness of denture resins and the bond, flexural strength, porosity and hardness of denture liners. The effects of microwave disinfection on the hardness of denture teeth and teeth/denture bond strength are still controversial and no safe conclusions can be drawn. PMID- 27688411 TI - Presentation of DMFT/dmft Index in Croatia and Europe. AB - BACKGROUND: Dental caries is the most common oral disease affecting all age groups and a major cause of tooth loss. Although a decrease in the prevalence of dental caries has been marked across the globe, in many countries it has remained a major oral-health problem. AIM: The objective of this paper was to show the trends in the DMFT/dmft index in Croatia, compare it with European countries and present further courses of action oriented towards promotion of oral health and decrease in caries prevalence. MATERIAL AND METHODS: The DMFT index databases have been generated based on online database searches for the period from 1985 to 2015. RESULTS: Croatia is one of European countries with a high DMFT index relating to 12-year old children (4.18). The experience of countries with a low DMFT index has shown that dental caries can be controlled through education and prevention activities, which eventually lead to diminished financial costs, at individual and national level, improving overall health and quality of life. CONCLUSION: Tracking and monitoring of oral health i.e. dental caries need to be improved in terms of creation of data base systems on the prevalence of dental caries, determining multi-factorial causes of its occurrence and with respect to the implementation of national oral-health prevention programs. PMID- 27688412 TI - A Comparative Study of Shaping Ability of four Rotary Systems. AB - PURPOSE: This study compared the cutting area, instrumentation time, root canal anatomy preservation and non-instrumented areas obtained by F360((r)), Mtwo((r)), RaCe((r)) and Hyflex((r)) files with ISO size 35. MATERIAL AND METHODS: 120 teeth with a single straight root and root canal were divided into 4 groups. Working length was calculated by using X-rays. The teeth were sectioned with a handpiece and a diamond disc, and the sections were observed with Nikon SMZ-2T stereoscopic microscope and an Intralux 4000-1 light source. The groups were adjusted with a preoperative analysis with AutoCAD. The teeth were reconstructed by a #10 K-File and epoxy glue. Each group was instrumented with one of the four file systems. The instrumentation time was calculated with a 1/100 second chronometer. The area of the thirds and root canal anatomy preservation were analyzed with AutoCAD 2013 and the non-instrumented areas with AutoCAD 2013 and SMZ-2T stereoscopic microscope. The statistical analysis was made with Levene's Test, ANOVA, Bonferroni Test and Pearson's Chi-square. RESULTS: Equal variances were shown by Levene's Test (P > 0.05). ANOVA (P > 0.05) showed the absence of significant differences. There were significant differences in the instrumentation time (P < 0.05). For root canal anatomy preservation and non-instrumented areas, there were no significant differences between all systems (P > 0.05). CONCLUSIONS: The 4 different rotary systems produced similar cutting area, root canal anatomy preservation and non-instrumented areas. Regarding instrumentation time, F360((r)) was the fastest system statistically. PMID- 27688414 TI - Four year Evaluation of Proximal Resin Infiltration in Adolescents. AB - AIM: Resin infiltration of proximal lesions is a new approach to stopping caries progression. Therefore, the aim of the present study was to evaluate four-year efficacy of proximal infiltrates in adolescents. MATERIALS AND METHODS: In ten adolescents, a total of 21 proximal infiltrates (ICON(r) (DMG, Germany) were applied to initial proximal lesions of permanent incisors and premolars according to the manufacturer's instruction. The clinical quality of resin infiltration was assessed at 1 week, 1, 2, 3 and 4 years after the treatment and the evaluation of the therapeutic effect was analyzed by radiographs. RESULTS: Ten patients were followed up clinically for four years. The majority of the infiltrated lesions were located on permanent incisors. Teeth which were proximally infiltrated did not exhibit dental plaque and gingival bleeding in most cases. At annual recalls, plaque scores remained constant. The gingival status remained steady and no differences in tooth shape and contour were detected. Discoloration was detected in four teeth (19%) in 1st year recall and was constant at annual intervals. The radiographic evaluation of the bitewing radiographs showed no progression in 21 lesions (100%) from baseline to the 4-year recall. Overall oral hygiene of the patients was satisfactory. CONCLUSION: In conclusion, proximal infiltration is an effective prophylactic measure in adolescents. PMID- 27688413 TI - Evaluation of Microbial Reduction in Root Canals Instrumented with Reciprocating and Rotary Systems. AB - OBJECTIVE: This in vitro study aimed to evaluate the efficacy of the disinfection of root canal systems carried out with Reciproc(TM) and ProTaper Universal(TM) systems using 1% sodium hypochlorite (NaOCl). METHODS: Forty human single-rooted mandibular premolars were infected with Enterococcus faecalis, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans, and twenty were not infected. The specimens were randomly divided into 6 groups (n = 10): Group 1: ProTaper Universal(TM) + 1% NaOCl; Group 2 (positive control): ProTaper Universal(TM) + saline; Group 3 (negative control without microorganisms): ProTaper Universal(TM) + saline; Group 4: Reciproc(TM) + 1% NaOCl; Group 5 (positive control): Reciproc(TM) + saline; Group 6 (negative control without microorganisms): Reciproc(TM) + saline. Samples were collected before and after the completion of specific treatments, and plated in specific media cultures. The Fisher exact test was used for the statistical analysis of differences in terms of presence or absence of microbial growth among groups. For all tested pathogens, significant differences (p < 0.001) were verified between the instrumentation systems used. RESULTS: ProTaper Universal(TM) associated with 1% NaOCl completely eliminated all microorganisms. Microbial growth, however, was observed when Reciproc(TM) was used associated with 1% NaOCl. CONCLUSION: According to the protocol executed for this study, the Reciproc(TM) system associated with 1% NaOCl was not able to completely eliminate E. faecalis, P. aeruginosa, S. aureus and C. albicans from the root canal systems. PMID- 27688415 TI - The Effect of Tobacco Smoking on Salivation. AB - AIM: The purpose of this study was to examine the detrimental effect of smoking on the function of the salivary glands. MATERIAL AND METHODS: The study was conducted on 60 patients who were divided into two groups: a test group which included smokers and control group represented by non-smokers. Each group included 30 patients. General information was collected from all the respondents via a questionnaire as well as the data on the duration of smoking and number of cigarettes smoked per day. Saliva was collected by spitting method in a graduated tube and the amount of unstimulated and stimulated saliva was measured and recorded in ml per minute. Stimulated saliva was collected immediately after rinsing the mouth with a 2% aqueous solution of citric acid which is carried salivary stimulation. The presence of pigmentation on the teeth and coated tongue were recorded during clinical examination. The degree of oral hygiene was determined by plaque index. All the obtained data were statistically analyzed with significance level p <0.05. RESULTS: The results showed no significant differences in the amount of saliva between smokers and non-smokers, however, the amount of saliva decreases significantly with the duration of smoking and increasing age of smokers. Also proven was the difference in the quality of saliva: smokers have thick saliva and nonsmokers predominantly serous. In addition, smokers have poorer oral hygiene status than non-smokers, and demonstrated a positive correlation between the level of oral hygiene and length of smoking tobacco. CONCLUSION: This study has proven that smoking adversely affects salivation: long-term smoking reduces the secretion of saliva and changes its quality. PMID- 27688416 TI - Flexible Removable Partial Denture Prosthesis: A Survey of Dentists' Attitudes and Knowledge in Greece and Croatia. AB - PURPOSE: The aim of this study was to investigate through a questionnaire the knowledge, attitudes and possible differences in the use of flexible RPDPs among dentists in Greece and Croatia. MATERIAL AND METHODS: A questionnaire of 16 questions was originally created in English, translated into Greek and Croatian language following a two way translation and tested for apprehension, precision, clarity and homogeneity by a number of native English speaking Greek and Croatian dentists. Following the necessary corrections, the questionnaires replicated in two online surveys and their addresses with an informed consent were sent by emails to nearly 4000 dentists in each country to participate. Collected data were analyzed by chi-square tests at a= .05 level of significance. RESULTS: 378 dentists from Greece and 304 from Croatia participated in the study. 137(36.2%) dentists from Greece and 56(18.4%) from Croatia provided flexible RPDPs to their patients. Statistical analysis for all providers indicated no significant difference between genders (P>.05), significant differences between age groups (P<.01), years of practice (P<.05), specialization (P <.001), and instruction on flexible prostheses (P <.001). The analysis between the two countries showed differences for gender and age groups (P<.01) but no differences between experienced, specialized or instructed groups (P >.05). CONCLUSION: The survey indicated differences between the two countries in the percentages of dentists using, selecting and providing RPDPs for their patients. Practitioners' age, years in practice and instruction were associated with the provision of the prostheses, while comfort, esthetics and cost were the reasons for deciding to use the flexible RPDPs. CONCLUSION: Although dentists are not educated in their schools about flexible RPDPs, almost a third of them offer this treatment to their patients. Long term success of these devices depends on clinical education, more experience and definitely more research. PMID- 27688417 TI - The Influence of Different Nonsteroidal Anti-Inflammatory Drugs on Alveolar Bone in Rats: An Experimental Study. AB - THE AIM: The aim of this study was to investigate the effect of dexketoprofen trometamol, meloxicam, diclofenac sodium on any untreated alveolar bone when they are used as drugs for another indication. MATERIALS AND METHODS: Twenty eight male Spraque-Dawley rats were randomized into four groups as dexketoprofen trometamol (Group I), meloxicam (Group II), diclofenac sodium (Group III) and control group. Nonsteroidal anti-inflammatory drugs (NSAID) were administered after a fibula fracture for 10 days. Untreated alveolar bone was histopathologically examined for spongious bone density, osteoclastic density and osteoblastic density. RESULTS: Spongious bone density was lower in study groups (Group I, group II and group III) than the control group (p<0.05). In contrast, the increase in osteoclastic density was observed in other groups apart from the control group (p<0.05). Osteoblastic density was evaluated and it was determined that group II and group III had lower results than the control group (p<0.05) but group I was equal to the control group. CONCLUSION: This study showed that systemically administrated NSAIDs have the potential to affect untreated alveolar bone. This should also be considered in long term use of NSAIDs. PMID- 27688418 TI - Mapping Electrical Impedance Spectra of the Healthy Oral Mucosa: a Pilot Study. AB - OBJECTIVE: Electrical impedance is the resistance to the electric current flow through a tissue and depends on the tissue's structure and chemical composition. The aim of this study was to map electrical impedance spectra for each region of the healthy oral mucosa. MATERIALS AND METHODS: Electrical impedance was measured in 30 participants with healthy oral mucosa. Measurements were performed in 14 points on the right and the left side of the oral cavity, and repeated after 7 and 14 days respectively. RESULTS: The lowest values were measured on the tongue dorsum and the highest values were measured on the hard palate. No significant differences were found between the right and the left side. Significantly higher values were found in females on the upper labial mucosa, tongue dorsum and the ventral tongue. Significant difference between smokers and non-smokers on the lower labial mucosa and floor of the mouth was found. Electrical impedance was negatively correlated with salivary flow on the upper labial mucosa, hard palate, tongue dorsum and sublingual mucosa. Higher variability of measurements was found at low frequencies. CONCLUSIONS: Electrical impedance mostly depends on the degree of mucosal keratinization. Demographic and clinical factors probably affect its values. Further studies with bigger number of participants are required. PMID- 27688420 TI - 50th Anniversary of Acta stomatologica Croatica.

PMID- 27688419 TI - Assessment of Oro-Maxillofacial Trauma According to Gender, Age, Cause and Type of the Injury. AB - OBJECTIVES: The occurrence and causes of maxillofacial trauma varies in different regions of the world. The aim of this study was to identify the occurrence, types and causes of maxillofacial injuries according to the age and gender differences in patients treated at the Department of Maxillofacial Surgery, University Hospital Center Osijek, between January 2011 and December 2013. MATERIALS AND METHODS: A total of 64 patients, 41 males (64.1%) and 23 females (35.9%), aged from 18 to 86 years (mean age 42) participated in the study. Data collected and analyzed included gender, age, cause of injury and the type of maxillofacial injuries. RESULTS: The most common cause of injuries in both gender groups was falling down (39% males; 65% females). The second leading cause of injuries in males was interpersonal violence (29%) and in females traffic accident (26%) (p<0.05). The most common type of injury in both gender groups was bone injury (50%; in males zygomatic bones 55%, in females mandible 40%) (p>0.05). The most common causes of injuries in the youngest patients was violence (43%), and in others fall (50-70%; p<0.05). The most common reported type of injury in all age groups was bone injury (more than 50%; p>0.05). The majority of the falls and violence caused bone tissue injuries, and soft tissue and dentalveolar injuries were detected in traffic and sports accidents (p>0.05). CONCLUSION: Falling down was the most common cause of oro-maxillofacial injuries in both men and women and in all three age groups. The leading type of injury was bone injury. The data obtained from this study provide important information for future prevention from injuries. PMID- 27688421 TI - Cytotoxicity of Two Bioactive Root Canal Sealers. AB - OBJECTIVE: The aim of this study was to investigate the cytotoxicity of two different bioactive root canal sealers: one based on mineral trioxide aggregate, MTA Fillapex (Angelus, Solucoes Odontologicas, Londrina, PR, Brazil), and the other based on bioceramics, Endosequence BC Sealer (Brasseler, Savannah, Georgia, USA), in culture of mouse L929 fibroblasts. MATERIALS AND METHODS: Mouse fibroblasts (L929), obtained from subcutaneous connective tissue of mouse line C3Hf, were cultivated in plastic culture flasks in an incubator at 37sC, with 5% CO2 and 90% humidity. Freshly mixed Endosequence BC Sealer and MTA Fillapex (0.1 g each) were placed on sterile teflon discs, 6 mm in diameter. Teflon discs with the materials as well as empty discs serving as control were placed in wells of 12-well plate. After incubation times of 1, 6, 20 and 24 hours, the teflon discs were removed from the wells and the number of viable cells was determined using trypan blue in Neubauer chamber. RESULTS: In comparison to the control group, MTA Fillapex had significantly less viable cells for all incubation periods (p<=0.05), while Endosequence BC sealer had significantly less viable cells after 6, 20, and 24 hours of incubation (p<=0.05). MTA Fillapex comprised significantly less viable cells in comparison to Endosequence BC sealer after the first hour and after 20 hours of incubation (p<=0.05), while for the other incubation periods there were no significant differences (p>=0.05). CONCLUSION: MTA Fillapex and Endosequence BC sealer were both cytotoxic in cultures of mouse L929 fibroblasts. PMID- 27688422 TI - Eradication of Intracanal Enterococcus Faecalis Biofilm by Passive Ultrasonic Irrigation and RinsEndo System. AB - AIM: The aim of the study was to compare the antimicrobial efficacy of three irrigation techniques after the use of standardized volume of NaOCl and with standardized time and irrigation. METHODOLOGY: Forty-eight single rooted teeth were inoculated with an Enterococcus faecalis suspension for 24 h. The remaining six canals served as negative controls. The 36 root canals were randomly distributed into three experimental groups; group 1, conventional syringe irrigation; group 2, automated-dynamic irrigation (RinsEndo); group 3, passive ultrasonic irrigation (PUI). In the first protocol, the standardized volume of 3% NaOCl (20 mL) was used and in the second protocol, and standardized irrigation time (45 seconds) was used. Samples from root canals were cultured and the colony forming units (CFUs) were counted. RESULTS: When the volume of the irrigant was standardized, RinsEndo was more effective than PUI (p<0.01). When the irrigation time was standardized, there were no significant differences between any irrigation techniques (p>0.05). The RinsEndo group had the highest percentage of minimal counts of E. faecalis CFUs. CONCLUSIONS: RinsEndo was more effective than PUI only when the volume of the irrigant was standardized. However, the RinsEndo provided higher bacterial reduction in both protocols when using the least amount of the irrigant and providing longer contact time. PMID- 27688423 TI - Evaluation of Periodontal Parameters in Patients with Early Stage Chronic Lymphocytic Leukemia. AB - OBJECTIVE: To assess periodontal conditions in patients with early stage CLL and to compare it with the periodontal status of age matched healthy controls and to analyze the relationship between periodontal and hematological parameters in CLL patients. MATERIALS AND METHODS: 60 subjects were examined: 30 patients with CLL Rai 0 (test group) and 30 age-matching healthy individuals (control group). The exclusion criteria were: presence of other systemic disease or condition (e.g. diabetes), history of treatment for periodontitis, use of antibiotics during the last 3 months, use of medications. Socio-demographic data were obtained by means of a questionnaire. Participants with at least 8 teeth underwent a full mouth examination assessing API, PBI, PPD, REC and CAL. Medical data for CLL patients were collected from the patients' records, while hematological data were obtained from the hemogram. RESULTS: Difference between groups was statistically significant for age, number of teeth and frequency of dental checkups (p<0.05). Patients with CLL had significantly higher average values of periodontal indices (API 0.81+/-0.18; PBI 2.72+/-0.68; PPD 3.40+/-0.53; REC 1.95+/-0.87, CAL 4.37+/ 0.80) compared to the control group (API 0.69+/-0.15; PBI 1.91+/-0.45; PPD 2.51+/ 0.40; REC 0.99+/-0.54; CAL 3.00+/-0.58). The correlation coefficients between age and periodontal indices showed statistically significance between age and REC (r=0.357; p<0.01), and age and CAL (r=0.295; p<0.05). Age was not statistically significant covariate for CAL (F=2.205; p>0.05), only for REC (F=4.601; p<0.05). After the removal of the statistical effect of age, the difference in REC between CLL and control group remained statistically significant (F=19.732; p<0.01; eta(2)=0.287). Statistically significant association between periodontal and hematological parameters in CLL patients was not found (p>0.05). CONCLUSION: The results of this study showed that patients with CLL had worse periodontal status compared to healthy subjects. Causal relationship between periodontal and hematological parameters was not proved. PMID- 27688424 TI - In Vivo Evaluations of Inter-Observer Reliability Using VITA Easyshade(r) Advance 4.0 Dental Shade-Matching Device. AB - OBJECTIVES: The aim of this study was to evaluate the inter-observer reliability of dental shade-matching device using an in vivo model. MATERIALS AND METHODS: Four observers who were well trained in color assessment and handling of the dental shade-matching device determined teeth color and CIE-Lab values on maxillary right central incisors in 10 patients with completely healthy and intact dentitions. VITA Easyshade(r) Advance 4.0 shade-matching device was utilized to measure the central region of the labial surface of all investigated teeth, twice by each observer. The inter-observer reliability of the measurements was observed and deviations between Lab and [Formula: see text]E values between the observers were calculated. Intraclass correlation coefficients (ICCs) were used to analyze inter-observer reliability. RESULTS: One-way ANOVA showed no statistically significant differences in color measurement of four observers in all the measured values (p>0.05). Delta E values ranged from 3.018 to 5.234. Although some small differences existed, statistically significant differences between the observers were not found (p>0.05). Inter-observer ICCs were very high for all observers (from 0.651 to 0.992). CONCLUSION: Inter-examiner reliability of measurements using VITA Easyshade(r) Advance 4.0 shade-matching device was acceptable. Apart from the digital equipment, a well trained observer seems to be crucial in order to achieve correct dental color measurement. PMID- 27688425 TI - Titanium Ions Release from an Innovative Titanium-Magnesium Composite: an in Vitro Study. AB - BACKGROUND: The innovative titanium-magnesium composite (Ti-Mg) was produced by powder metallurgy (P/M) method and is characterized in terms of corrosion behavior. MATERIAL AND METHODS: Two groups of experimental material, 1 mass% (Ti 1Mg) and 2 mass% (Ti-2Mg) of magnesium in titanium matrix, were tested and compared to commercially pure titanium (CP Ti). Immersion test and chemical analysis of four solutions: artificial saliva; artificial saliva pH 4; artificial saliva with fluoride and Hank balanced salt solution were performed after 42 days of immersion, using inductively coupled plasma mass spectrometry (ICP-MS) to detect the amount of released titanium ions (Ti). SEM and EDS analysis were used for surface characterization. RESULTS: The difference between the results from different test solutions was assessed by ANOVA and Newman-Keuls test at p<0.05. The influence of predictor variables was found by multiple regression analysis. The results of the present study revealed a low corrosion rate of titanium from the experimental Ti-Mg group. Up to 46 and 23 times lower dissolution of Ti from Ti-1Mg and Ti-2Mg, respectively was observed compared to the control group. Among the tested solutions, artificial saliva with fluorides exhibited the highest corrosion effect on all specimens tested. SEM micrographs showed preserved dual phase surface structure and EDS analysis suggested a favorable surface bioactivity. CONCLUSION: In conclusion, Ti-Mg produced by P/M as a material with better corrosion properties when compared to CP Ti is suggested. PMID- 27688426 TI - Education on occupational health and health related habits among dental students in Croatia. AB - INTRODUCTION: Occupational diseases are diseases caused by occupational exposures at the workplace, while diseases related to work are diseases caused by many factors, wherein the harmful work conditions are one of the possible causes. Dental medicine is a profession with a high risk of developing occupational diseases. The aim of this paper was to present the results of a survey about occupational health risks and health related habits among dental students at the School of Dental Medicine University of Zagreb and to show how this survey led to an improvement in education by introducing a new course into the dental curriculum. PARTICIPANTS AND METHODS: Students of all years at the School of Dental Medicine University of Zagreb (total of 663) were offered to participate in a survey about occupational health risks and health related habits. RESULTS: A questionnaire was completed by 351 students. 28.0% of male students and 22.5% of female students were smokers. During the first two years of study, up to 84.6% of students consumed alcoholic beverages at least once a week. Prior to enrollment in the university, 85.3% male and 77.6% female students were engaged in sports. The significant drop in the number of students who participated in sports was noticed in the first study year in both sexes. Student awareness of the health risks related to dental profession increases with the year of study. Most students believe that occupational diseases can be prevented. CONCLUSION: The results have shown that students enter the School of Dental Medicine with a relatively low level of awareness of the health hazards of dental profession. Although the level of awareness increases with years of study, harmful habits such as smoking, alcohol consumption, and the lack of physical activity also remain present in the later years of study. PMID- 27688427 TI - Prevalence and Pattern of Non-Syndromic Hypodontia in a Group of Turkish Children. AB - OBJECTIVE: The aim of this study was to assess the prevalence and pattern of congenital missing teeth in the permanent dentition (excluding wisdom teeth), among Turkish children in a 4-year period (2009-2012). METHODS: The study group comprised 1658 children (873 girls, 785 boys). The children were examined in Department of Pediatric Dentistry, Dental School of Marmara University. A chi square test was used to determine the difference in the prevalence of hypodontia between genders. RESULTS: The prevalence of hypodontia was 6.2% (6.3% girls, 6% boys) with no statistically significant difference between the genders (P=0.601). The most frequently missing tooth were the mandibular left second premolars, 63 (20.7%), followed by the mandibular right second premolars, 61(20.1%), maxillary left premolars, 31 (10.2%). There were 89 anterior and 214 posterior missing teeth. Bilateral hypodontia was observed in 70 (39 girls, 31 boys) patients (67.9%). The most common bilateral missing teeth were the mandibular second premolar (22 girls, 21 boys) (42.1%) and the maxillary second premolar (6 girls, 15 boys) (20.5%). The mandibular left second premolar (9 boys, 8 girls) was the most frequent unilaterally missing tooth (5.6%) followed by the mandibular right second premolar (10 girls, 6 boys) (5.28%). CONCLUSION: The obtained results point to the importance of detailed clinical and radiographic examination. These help with long-term treatment planning according to a child's individual requirements. PMID- 27688428 TI - Developmental Defects of Enamel in Children with Intellectual Disability. AB - OBJECTIVES: To investigate the frequency of developmental defects of enamel (DDE) in children with intellectual disability. SUBJECTS AND METHODS: Children aged 5 18 years (72 children with intellectual disabilities and 72 controls) were included in the study. All the teeth were screened for developmental defects of enamel using the modified Developmental defects of enamel (mDDE) index. RESULTS: Out of the 72 children with intellectual disabilities in this study, 20 (27.78%) presented dental defects of enamel, compared with 8 (11.11%) of those in the control group, which was considered statistically significant (p = 0.021). The majority of children in both groups had white demarcated opacities. Children in both groups were more likely to have maxillary teeth affected than the mandibular teeth and the asymmetrical demarcated enamel defects were more common than the symmetric ones. Majority of opacities in children in both groups were on the maxillary incisors. CONCLUSIONS: Children with intellectual disabilities have more developmental defects of enamel than children in the control group. Enamel defects increase caries risk and cause reduction in enamel mechanical properties leading to restoration failures. PMID- 27688429 TI - Medical Emergencies in Pediatric Dentistry. AB - Medical emergencies that are life threatening can occur in dental practice. Complications may arise because of an underlying disease or a reaction to medication. Reactions to medications may be allergic and toxic. The most common reactions are toxic reactions to local anesthetics, whereas allergies occur mainly as a consequence of the application of antibiotics, usually penicillin. In response to stress, vasovagal syncope typically occurs. Other causes may be related to an underlying disease-specific pathology (such as acute asthma attack, diabetic ketoacidosis, hypoglycemia, or seizures) or accidents (aspiration of a foreign body causing obstruction of the respiratory system). For all the above conditions, guidelines have been established that need to be known. If complications occur or necessary measures are not taken, it can lead to cardiac and respiratory arrest. Therefore, cardiopulmonary resuscitation is needed. All procedures and dosages should be adapted to the age of the child. PMID- 27688430 TI - Farms, Families, and Markets: New Evidence on Completeness of Markets in Agricultural Settings. AB - The farm household model has played a central role in improving the understanding of small-scale agricultural households and non-farm enterprises. Under the assumptions that all current and future markets exist and that farmers treat all prices as given, the model simplifies households' simultaneous production and consumption decisions into a recursive form in which production can be treated as independent of preferences of household members. These assumptions, which are the foundation of a large literature in labor and development, have been tested and not rejected in several important studies including Benjamin (1992). Using multiple waves of longitudinal survey data from Central Java, Indonesia, this paper tests a key prediction of the recursive model: demand for farm labor is unrelated to the demographic composition of the farm household. The prediction is unambiguously rejected. The rejection cannot be explained by contamination due to unobserved heterogeneity that is fixed at the farm level, local area shocks or farm-specific shocks that affect changes in household composition and farm labor demand. We conclude that the recursive form of the farm household model is not consistent with the data. Developing empirically tractable models of farm households when markets are incomplete remains an important challenge. PMID- 27688431 TI - W' expenditure and reconstitution during severe intensity constant power exercise: mechanistic insight into the determinants of W'. AB - The sustainable duration of severe intensity exercise is well-predicted by critical power (CP) and the curvature constant (W'). The development of the W'BAL model allows for the pattern of W' expenditure and reconstitution to be characterized and this model has been applied to intermittent exercise protocols. The purpose of this investigation was to assess the influence of relaxation phase duration and exercise intensity on W' reconstitution during dynamic constant power severe intensity exercise. Six men (24.6 +/- 0.9 years, height: 173.5 +/- 1.9 cm, body mass: 78.9 +/- 5.6 kg) performed severe intensity dynamic handgrip exercise to task failure using 50% and 20% duty cycles. The W'BAL model was fit to each exercise test and the time constant for W' reconstitution (tauW') was determined. The tauW' was significantly longer for the 50% duty cycle (1640 +/- 262 sec) than the 20% duty cycle (863 +/- 84 sec, P = 0.02). Additionally, the relationship between tauW' and CP was well described as an exponential decay (r(2) = 0.90, P < 0.0001). In conclusion, the W'BAL model is able to characterize the expenditure and reconstitution of W' across the contraction-relaxation cycles comprising severe intensity constant power handgrip exercise. Moreover, the reconstitution of W' during constant power severe intensity exercise is influenced by the relative exercise intensity, the duration of relaxation between contractions, and CP. PMID- 27688432 TI - Leucine-rich repeat containing protein LRRC8A is essential for swelling-activated Cl- currents and embryonic development in zebrafish. AB - A volume-regulated anion channel (VRAC) has been electrophysiologically characterized in innumerable mammalian cell types. VRAC is activated by cell swelling and mediates the volume regulatory efflux of Cl(-) and small organic solutes from cells. Two groups recently identified the mammalian leucine-rich repeat containing protein LRRC8A as an essential VRAC component. LRRC8A must be coexpressed with at least one of the other four members of this gene family, LRRC8B-E, to reconstitute VRAC activity in LRRC8(-/-) cells. LRRC8 genes likely arose with the origin of chordates. We identified LRRC8A and LRRC8C-E orthologs in the zebrafish genome and demonstrate that zebrafish embryo cells and differentiated adult cell types express a swelling-activated Cl(-) current indistinguishable from mammalian VRAC currents. Embryo cell VRAC currents are virtually eliminated by morpholino knockdown of the zebrafish LRRC8A ortholog lrrc8aa VRAC activity is fully reconstituted in LRRC8(-/-) human cells by coexpression of zebrafish lrrc8aa and human LRRC8C cDNAs. lrrc8aa expression varies during zebrafish embryogenesis and lrrc8aa knockdown causes pericardial edema and defects in trunk elongation and somatogenesis. Our studies provide confirmation of the importance of LRRC8A in VRAC activity and establish the zebrafish as a model system for characterizing the molecular regulation and physiological roles of VRAC and LRRC8 proteins. PMID- 27688433 TI - Contraction mode itself does not determine the level of mTORC1 activity in rat skeletal muscle. AB - Resistance training with eccentric contraction has been shown to augment muscle hypertrophy more than other contraction modes do (i.e., concentric and isometric contraction). However, the molecular mechanisms involved remain unclear. The purpose of this study was to investigate the effect of muscle contraction mode on mammalian target of rapamycin complex 1 (mTORC1) signaling using a standardized force-time integral (load (weight) * contraction time). Male Sprague-Dawley rats were randomly assigned to three groups: eccentric contraction, concentric contraction, and isometric contraction. The right gastrocnemius muscle was exercised via percutaneous electrical stimulation-induced maximal contraction. In experiment 1, different modes of muscle contraction were exerted using the same number of reps in all groups, while in experiment 2, muscle contractions were exerted using a standardized force-time integral. Muscle samples were obtained immediately and 3 h after exercise. Phosphorylation of molecules associated with mTORC1 activity was assessed using western blot analysis. In experiment 1, the force-time integral was significantly different among contraction modes with a higher force-time integral for eccentric contraction compared to that for other contraction modes (P < 0.05). In addition, the force-time integral was higher for concentric contraction compared to that for isometric contraction (P < 0.05). Similarly, p70S6K phosphorylation level was higher for eccentric contraction than for other modes of contraction (P < 0.05), and concentric contraction was higher than isometric contraction (P < 0.05) 3 h after exercise. In experiment 2, under the same force-time integral, p70S6K (Thr389) and 4E-BP1 phosphorylation levels were similar among contraction modes 3 h after exercise. Our results suggest that mTORC1 activity is not determined by differences in muscle contraction mode itself. Instead, mTORC1 activity is determined by differences in the force-time integral during muscle contraction. PMID- 27688435 TI - Lichen Planus Pigmentosus: The Controversial Consensus. AB - A pigmented variant of lichen planus (LP) was first reported from India in 1974 by Bhutani et al. who coined the term LP pigmentosus (LPP) to give a descriptive nomenclature to it. LP has a number of variants, one of which is LPP. This disease has also later been reported from the Middle East, Latin America, Korea, and Japan, especially in people with darker skin. It has an insidious onset. Initially, small, black or brown macules appear on sun-exposed areas. They later merge to form large hyperpigmented patches. The disease principally affects the sun-exposed areas of the body such as the face, trunk, and upper extremities. The oral mucosa may rarely be involved. However, the palms, soles, and nails are not affected. Histologically, the epidermis is atrophic along with vacuolar degeneration of basal cell layer. The dermis exhibits incontinence of pigment with scattered melanophages and a sparse follicular or perivascular infiltrate. There is a considerable similarity in histopathological findings between LPP and erythema dyschromicum perstans. However, there are immunologic and clinical differences between the two. These observations have led to a controversy regarding the identity of the two entities. While some dermatologists consider them to be the same, others have opined that the two should be considered as distinctly different diseases. A number of associations such as hepatitis C virus infection, frontal fibrosing alopecia, acrokeratosis of Bazex and nephrotic syndrome have been reported with LPP. A rare variant, LPP inversus, with similar clinical and histopathological findings was reported in 2001. As opposed to LPP, this variant occurs in covered intertriginous locations such as groins and axillae and mostly affects white-skinned persons. PMID- 27688437 TI - Biostatistics Series Module 5: Determining Sample Size. AB - Determining the appropriate sample size for a study, whatever be its type, is a fundamental aspect of biomedical research. An adequate sample ensures that the study will yield reliable information, regardless of whether the data ultimately suggests a clinically important difference between the interventions or elements being studied. The probability of Type 1 and Type 2 errors, the expected variance in the sample and the effect size are the essential determinants of sample size in interventional studies. Any method for deriving a conclusion from experimental data carries with it some risk of drawing a false conclusion. Two types of false conclusion may occur, called Type 1 and Type 2 errors, whose probabilities are denoted by the symbols sigma and beta. A Type 1 error occurs when one concludes that a difference exists between the groups being compared when, in reality, it does not. This is akin to a false positive result. A Type 2 error occurs when one concludes that difference does not exist when, in reality, a difference does exist, and it is equal to or larger than the effect size defined by the alternative to the null hypothesis. This may be viewed as a false negative result. When considering the risk of Type 2 error, it is more intuitive to think in terms of power of the study or (1 - beta). Power denotes the probability of detecting a difference when a difference does exist between the groups being compared. Smaller alpha or larger power will increase sample size. Conventional acceptable values for power and alpha are 80% or above and 5% or below, respectively, when calculating sample size. Increasing variance in the sample tends to increase the sample size required to achieve a given power level. The effect size is the smallest clinically important difference that is sought to be detected and, rather than statistical convention, is a matter of past experience and clinical judgment. Larger samples are required if smaller differences are to be detected. Although the principles are long known, historically, sample size determination has been difficult, because of relatively complex mathematical considerations and numerous different formulas. However, of late, there has been remarkable improvement in the availability, capability, and user-friendliness of power and sample size determination software. Many can execute routines for determination of sample size and power for a wide variety of research designs and statistical tests. With the drudgery of mathematical calculation gone, researchers must now concentrate on determining appropriate sample size and achieving these targets, so that study conclusions can be accepted as meaningful. PMID- 27688438 TI - Methodology Series Module 5: Sampling Strategies. AB - Once the research question and the research design have been finalised, it is important to select the appropriate sample for the study. The method by which the researcher selects the sample is the ' Sampling Method'. There are essentially two types of sampling methods: 1) probability sampling - based on chance events (such as random numbers, flipping a coin etc.); and 2) non-probability sampling - based on researcher's choice, population that accessible & available. Some of the non-probability sampling methods are: purposive sampling, convenience sampling, or quota sampling. Random sampling method (such as simple random sample or stratified random sample) is a form of probability sampling. It is important to understand the different sampling methods used in clinical studies and mention this method clearly in the manuscript. The researcher should not misrepresent the sampling method in the manuscript (such as using the term ' random sample' when the researcher has used convenience sample). The sampling method will depend on the research question. For instance, the researcher may want to understand an issue in greater detail for one particular population rather than worry about the ' generalizability' of these results. In such a scenario, the researcher may want to use ' purposive sampling' for the study. PMID- 27688434 TI - Anti-inflammatory and Immunomodulatory Effects of Antibiotics and Their Use in Dermatology. AB - Antibiotics (antibacterial, antiviral, and antiparasitic) are class of drugs which result in either killing or inhibiting growth and multiplication of infectious organisms. Antibiotics are commonly prescribed by all specialties for treatment of infections. However, antibiotics have hitherto immunomodulatory and anti-inflammatory properties and can be exploited for various noninfectious dermatoses. Dermatologists routinely prescribe antibiotics in treatment of various noninfectious disorders. This study will review anti-inflammatory and immunomodulatory effects of antibiotics and their use in dermatology. PMID- 27688439 TI - Significance of Anti-cyclic Citrullinated Peptide Autoantibodies in Immune mediated Inflammatory Skin Disorders with and without Arthritis. AB - BACKGROUND: Anti-cyclic citrullinated peptides (CCPs) are autoantibodies directed against citrullinated peptides. Rheumatoid factor (RF), an antibody against the Fc portion of IgG, is known to form immune complexes and contribute to the etiopathogenesis of various skin disorders. C-reactive protein (CRP), an acute phase protein, increases following secretion of interleukin-6 from macrophages and T cells. Anti-CCP, RF, and CRP are well-established immune-markers, their diagnostic potential in immune-mediated skin disorders remains less widely studied. AIMS AND OBJECTIVES: To determine the correlation between anti-CCP, RF, and CRP in immune-mediated inflammatory skin diseases. MATERIALS AND METHODS: About 61 clinically diagnosed cases of various immune-mediated skin diseases (psoriasis [n = 38], connective tissue diseases such as systemic lupus erythematosus and systemic sclerosis [n = 14], and immunobullous disorders including pemphigus vulgaris and pemphigus foliaceus [n = 9]) were included in the study. These patients were subclassified on the basis of presence or absence of arthritis. Arthritis was present in nine cases of psoriasis and seven connective tissue disorder patients. Detection of serum anti-CCP was done using enzyme-linked immunosorbent assay, whereas CRP and RF levels were detected using latex agglutination technique. RESULTS: Of the 61 specimens, 14.75% had elevated serum anti-CCP levels. RF and CRP levels were elevated in 18.03% and 39.34% specimens, respectively. RF was elevated in 13.16% of inflammatory and 42.88% of connective tissue disorders, whereas anti-CCP was raised in 10.53% of inflammatory and 35.71% of connective tissue disorders. CRP positivity was highest in connective tissue disorders (50%), followed by 39.47% in inflammatory and 22.22% in immunobullous conditions. In none of the immunobullous patients, anti-CCP or RF levels were found to be elevated. Association of the presence of arthritis with elevated anti-CCP was found to be statistically significant. CONCLUSIONS: Although anti-CCP, RF, and CRP levels are valuable markers of chronic immune-mediated skin disorders, elaborate studies enrolling a larger number of patients are required to validate these diagnostic markers. PMID- 27688440 TI - The Psychosocial Impact of Acne Vulgaris. AB - BACKGROUND: Acne vulgaris causes erythematous papulopustular lesions in active stage and often leave behind residual scarring and pigmentation. Its onset in adolescence may add to the emotional and psychological challenges experienced during this period. AIMS: To assess the impact of acne on the various psychosocial domains of daily life. MATERIALS AND METHODS: This was a prospective, cross-sectional study done in the dermatology out-patient department of a tertiary care hospital from January to March 2015. A total of 100 consecutive, newly diagnosed patients of acne vulgaris, aged 15 years and above were included in this study. The relationship between acne vulgaris and its sequelae was analyzed with ten different domains of daily life by using dermatology life quality index (DLQI) questionnaire. RESULTS: Females (56%), 15 20 year olds (61%), facial lesions (60%), and Grade II acne (70%) were most common. Acne scars were noted in 75% patients, whereas 79% cases had post-acne hyperpigmentation. Thirty-seven percent patients had DLQI scores of (6-10) interpreted as moderate effect on patient's life. Statistically significant correlation (P < 0.05) found were as follows: Physical symptoms with grade of acne; embarrassment with site and grade of acne; daily activities with grade of acne and post-acne pigmentation; choice of clothes with site of acne; social activities with gender, site and grade of acne; effect on work/study with grade of acne; interpersonal problems with site and post-acne pigmentation; sexual difficulties with grade of acne. LIMITATION: It was a hospital-based study with small sample size. CONCLUSION: Significant impact of acne and its sequelae was noted on emotions, daily activities, social activities, study/work, and interpersonal relationships. Assurance and counseling along with early treatment of acne vulgaris is important to reduce disease-related psychosocial sequelae and increase the efficacy of treatment. PMID- 27688436 TI - Skin Hyperpigmentation in Indian Population: Insights and Best Practice. AB - Skin pigmentation is one of the most strikingly variable phenotypes in humans, therefore making cutaneous pigmentation disorders frequent symptoms manifesting in a multitude of forms. The most common among them include lentigines, postinflammatory hyperpigmentation, dark eye circles, and melasma. Variability of skin tones throughout the world is well-documented, some skin tones being reported as more susceptible to pigmentation disorders than others, especially in Asia and India. Furthermore, exposure to ultraviolet radiation is known to trigger or exacerbate pigmentation disorders. Preventive strategies for photoprotection and treatment modalities including topical and other medical approaches have been adopted by dermatologists to mitigate these disorders. This review article outlines the current knowledge on pigmentation disorders including pathophysiology, molecular profiling, and therapeutic options with a special focus on the Indian population. PMID- 27688441 TI - Cutaneous Leishmaniasis in a Nonendemic Area of South Rajasthan: A Prospective Study. AB - BACKGROUND: Cutaneous leishmaniasis (CL) usually occurs in areas with hot and dry climate. In India, the desert areas of Rajasthan, Gujarat, and the plains of Northwestern frontier are endemic for this disorder. AIMS AND OBJECTIVES: The present study was aimed to describe clinicoepidemiological profile of the cases of CL from South Rajasthan, which is a nonendemic area of Rajasthan. MATERIALS AND METHODS: During a period of 4 years (2010-2014), a total of 23 patients with CL were diagnosed. All the suspected cases of CL were interrogated in detail regarding visit to areas where CL is known to occur. This was followed by clinical examination, relevant investigations, and treatment. All except one patient were treated with azole antifungals. In one patient, CO2 laser ablation was done. RESULTS: There were 12 (52.17%) males and 11 (47.83%) females with age ranging from 3 to 72 years. Duration of disease ranged from 7 days to 10 months. Face (15; 65.22%) and extremities (12; 52.17%) were involved in majority of the patients. Common morphologies were noduloulcerative lesions and crusted plaques. Tissue smear for Leishmania donovani bodies was positive in all except one patient. CONCLUSION: The present report highlights occurrence of CL in nonendemic area. Further epidemiological studies are required for identification of vector and strain of Leishmania involved. PMID- 27688442 TI - Dermatoses among Children from Celebration of "Holi," the Spring Festival, in India: A Cross-sectional Observational Study. AB - BACKGROUND: "Holi" is a spring festival celebrated primarily in the Indian subcontinent and also abroad by expatriate Indians. It is a festival of colors, traditionally celebrated by mutual application of colors in different forms on a particular day of the year. These colors frequently comprise a range of synthetic dyes which have harmful effects on the skin and mucosae. Children take part in this colorful festival with much enthusiasm and vigor, making them prone to develop different "Holi"-related dermatoses. Our objective was to find out the different patterns of "Holi"-related dermatoses in a group of pediatric patients. METHODOLOGY: This was a cross-sectional descriptive study carried out over a period of 6 years (2010-2015). Consecutive patients of pediatric age group who attended dermatology outpatient department (OPD) with different dermatoses following application of "Holi" color were included in this study. RESULTS: A total of 63 patients (mean age 11 years; range 1-16 years) were evaluated with a female to male ratio of 1.3:1. Itching is the predominant presenting symptom followed by burning sensation, dryness, scaling, oozing, and loss of hair. Examination revealed that eczematous lesion was the most common (69.8%) reaction pattern followed by xerosis, desquamation, excoriation, erythema, morbilliform eruption, erosion, alopecia, ulceration, acute paronychia, and hyperpigmentation. The face was the most common (76.4%) site of affection. CONCLUSION: A sizable number of patients of pediatric age group may be affected by "Holi"-related dermatoses necessitating precautionary measures. PMID- 27688443 TI - Relapse after Oral Terbinafine Therapy in Dermatophytosis: A Clinical and Mycological Study. AB - BACKGROUND: The incidence of recurrent tinea infections after oral terbinafine therapy is on the rise. AIM: This study aims to identify the appearance of incomplete cure and relapse after 2-week oral terbinafine therapy in tinea corporis and/or tinea cruris. MATERIALS AND METHODS: A total of 100 consecutive patients clinically and mycologically diagnosed to have tinea corporis and/or tinea cruris were included in the study. The enrolled patients were administered oral terbinafine 250 mg once daily for 2 weeks. All clinically cured patients were then followed up for 12 weeks to look for any relapse/cure. RESULTS: The common dermatophytes grown on culture were Trichophyton rubrum and Trichophyton tonsurans in 55% and 20% patients, respectively. At the end of 2-week oral terbinafine therapy, 30% patients showed a persistent disease on clinical examination while 35% patients showed a persistent positive fungal culture (persisters) at this time. These culture positive patients included all the clinically positive cases. Rest of the patients (65/100) demonstrated both clinical and mycological cure at this time (cured). Over the 12-week follow-up, clinical relapse was seen in 22 more patients (relapse) among those who had shown clinical and mycological cure at the end of terbinafine therapy. Thus, only 43% patients could achieve a long-term clinical and mycological cure after 2 weeks of oral terbinafine treatment. Majority of the relapses (16/22) were seen after 8 weeks of completion of treatment. There was no statistically significant difference in the body surface area involvement or the causative organism involved between the cured, persister, or relapse groups. CONCLUSIONS: Incomplete mycological cure as well as relapse is very common after standard (2-week) terbinafine therapy in our patients of tinea cruris/corporis. PMID- 27688444 TI - A Prospective Study of Herpes Zoster in Children. AB - BACKGROUND: Herpes zoster (HZ) is a dermatomal viral infection, caused by reactivation of varicella zoster virus (VZV) that persists in the posterior root ganglion. HZ is uncommonly reported in immunocompetent children. It may be due to intrauterine VZV infection or secondary to postnatal exposure to VZV at an early age. AIMS: Our study was to review clinico-epidemiological data for HZ in children for early diagnosis and treatment to prevent complications. MATERIALS AND METHODS: A prospective observational study was conducted from January 2013 to December 2014. Consecutive cases clinically diagnosed as HZ in the pediatric age group were taken up. RESULTS: We report the clinico-epidemiological study of 26 cases of HZ, their benign course and recovery among children. CONCLUSIONS: HZ is a rare disease in childhood. Varicella in early childhood is a risk factor of HZ in immunocompromised and immunocompetent children. Childhood zoster occurs in either healthy or underlying immunodeficient children. The appearance of HZ in a young child does not always imply an underlying immunodeficiency or malignancy. But the identification of HZ with or without immunodeficiency is of prime importance from the treatment and prognostic point of view and should be considered in the differential diagnosis of vesicular eruptions. The prognosis is generally good in healthy children. PMID- 27688445 TI - Three Hundred Patients Treated with Ultrapulsed 980 nm Diode Laser for Skin Disorders. AB - The use of lasers in skin diseases is quite common. In contrast to other laser types, medical literature about 980 nm ultrapulsed diode laser is sparse in dermatology. Herein, we report the use of ultrapulsed diode 980 nm laser in 300 patients with vascular lesions, cysts and pseudocysts, infectious disease, and malignant tumors. This laser is a versatile tool with excellent safety and efficacy in the hands of the experienced user. PMID- 27688449 TI - IJD((r)) WINDOW. PMID- 27688446 TI - Efficacy of Intense Pulsed Light Therapy in the Treatment of Facial Acne Vulgaris: Comparison of Two Different Fluences. AB - BACKGROUND: Acne vulgaris is the most common disease of the skin affecting adolescents and young adults causing psychological distress. The combination of antibiotic resistance, adverse effects of topical and systemic anti acne medications and desire for high tech approaches have all led to new enthusiasm for light based acne treatment. Intense pulse light (IPL) therapy has three modes of action in acne vulgaris i.e., photochemical, photo thermal and photo immunological. AIMS: (1) to study efficacy of IPL therapy in facial acne vulgaris. (2) To compare two fluences - one normal and other subnormal on right and left side of face respectively. METHODS: (Including settings and design and statistical analysis used). Total 45 patients in age group 16 to 28 years with inflammatory facial acne vulgaris were included in prospective study. Baseline data for each patient was recorded. All patients were given 4 sittings of IPL at 2 weeks interval and were followed for 2 months every 2 weeks. Fluence used was 35J/cm(2) on right and 20J/cm(2) on left side. Percentage reduction in lesion count was calculated at each sitting and follow up and graded as mild (0-25%), moderate (26-50%), good (51-75%) and excellent (76-100%). Side effects were noted. The results were analysed using Mann-Whitney Test. RESULTS: On right side, excellent results were achieved in 10(22%), good in 22(49%) and moderate in 13(29%) patients. On left side excellent were results achieved in 7(15%), good in 19(42%) and moderate in 16(43%) patients. There was no statically significant difference noted in efficacy of two fluences used in treatment of facial acne vulgaris. CONCLUSIONS: IPL is a effective and safe option for inflammatory acne vulgaris with minimal reversible side effects. Subnormal fluence is as effective as normal fluence in Indian skin. PMID- 27688447 TI - Belimumab in Systemic Lupus Erythematosus. AB - Belimumab is the only approved biological agent for the treatment of systemic lupus erythematosus (SLE). It is a fully humanized IgG1gamma monoclonal antibody directed against soluble B lymphocyte stimulator (BLyS). It is indicated as an add-on therapy for the treatment of adult patients with active, autoantibody positive SLE, who are receiving standard therapy. Belimumab is generally well tolerated, common adverse effects include infections, infusion reactions, hypersensitivity, headache, nausea, and fatigue. Psychiatric events including suicidal tendency, progressive multifocal leukoencephalopathy and malignancies too have been reported. Apart from SLE, the drug is also being tried for other autoimmune disorders. PMID- 27688448 TI - Folliculotropic Mycosis Fungoides: Clinical and Histologic Features in Five Patients. AB - BACKGROUND: Alopecia can be a manifestation of mycosis fungoides (MF); however, the prevalence is unknown. AIMS: We sought to describe the clinicopathologic presentation of alopecia in patients with diagnosis of MF. METHODS: A retrospective analysis of patients with biopsy-proven MF, who were evaluated at our cancer center from 2002 to 2012, was performed to identify patients with alopecia. RESULTS: Five patients with alopecia were identified from reviewing of 157 patients with MF. The male:female ratio was 3:2, and the mean age of patients was 42.8 years. Two of these patients showed patchy hair loss on scalp which was clinically identical to alopecia areata. In remaining three patients, hair loss was seen in areas of MF lesions, and epidermal changes consisted of patch- and plaque-type lesions of MF, tumors, and follicular lesions (follicular MF) were also present. In two of these patients, lymphadenopathy without any visceral involvement was detected. CONCLUSIONS: Alopecia was observed in 5 (3.18%) patients with MF, which makes it a rare finding, which included alopecia areata like patchy loss in 2 and alopecia within MF lesions in 3. PMID- 27688450 TI - Inpatient Dermatology: Characteristics of Patients and Admissions in a Tertiary Level Hospital in Eastern India. AB - INTRODUCTION: Dermatology is primarily a non-acute, outpatient-centered clinical specialty, but substantial number of patients need indoor admission for adequate management. Over the years, the need for inpatient facilities in Dermatology has grown manifold; however, these facilities are available only in some tertiary centers. AIMS AND OBJECTIVES: To analyze the characteristics of the diseases and outcomes of patients admitted in the dermatology inpatient Department of a tertiary care facility in eastern India. MATERIALS AND METHODS: We undertook a retrospective analysis of the admission and discharge records of all patients, collected from the medical records department, admitted to our indoor facility from 2011 to 2014. The data thus obtained was statistically analyzed with special emphasis on the patient's demographic profile, clinical diagnosis, final outcome, and duration of stay. RESULTS AND ANALYSIS: A total of 375 patients were admitted to our indoor facility during the period. Males outnumbered females, with the median age in the 5th decade. Immunobullous disorders (91 patients, 24.27%) were the most frequent reason for admissions, followed by various causes of erythroderma (80 patients, 21.33%) and infective disorders (73 patients, 19.47%). Other notable causes included cutaneous adverse drug reactions, psoriasis, vasculitis, and connective tissue diseases. The mean duration of hospital stay was 22.2+/-15.7 days; ranging from 1 to 164 days. Majority of patients (312, 83.2%) improved after hospitalization; while 29 (7.73%) patients died from their illness. About 133 patients (35.64%) required referral services during their stay, while 8 patients (2.13%) were transferred to other departments for suitable management. CONCLUSION: Many dermatoses require inpatient care for their optimum management. Dermatology inpatient services should be expanded in India to cater for the large number of cases with potentially highly severe dermatoses.

The diagnosis of classic MF is based on a constellation of typical clinical presentation, histopathology, immunohistochemistry, and T-cell monoclonality detected by molecular studies. Rarely, atypical clinical presentation may occur. The typical immunohistochemical phenotype is, CD2 +ve, CD3 +ve, CD5 +ve, CD4 +ve, and CD8 - ve. Here, we report a rare case of CD8 +ve MF in a 43-year-male patient who was clinically diagnosed as pyoderma gangrenosum initially. The atypical presentation and rarity of such case have prompted this report. PMID- 27688459 TI - Heterozygous Cylindromatosis Gene Mutation c.1628_1629delCT in a Family with Brook-Spiegler Syndrome. AB - Brooke-Spiegler Syndrome (BSS) is a rare genodermatosis characterized by the progressive formation of adnexal skin tumors in the scalp and face, mainly trichoepitheliomas, cylindromas, and spiradenomas. It has also been associated with salivary glands neoplasms. It is due to mutations in the tumor suppressor gene cylindromatosis (CYLD gene) localized on chromosome 16q12-q13. Around 93 mutations have been described. The study of CYLD gene in patients and their relatives is of vital importance to establish the molecular diagnosis and offer appropriate genetic counseling. There is a low risk of malignancy and patients require long-term follow-up. A case of BSS in a family is described. The existence of the genetic mutation at the CYLD gene c. 1628_1629delCT in three of the women affected was demonstrated. This mutation has only been described once in a previous study. PMID- 27688460 TI - Experience of Varied Presentation of Chronic Progressive Disseminated Histoplasmosis in Immunocompetent Patients: A Diagnostic Conundrum. AB - We report two cases of chronic progressive disseminated histoplasmosis with unusual and rare clinical picture in a patient with no underlying risk factor. One 50-year-old male, presented with hoarseness of voice, chronic cough, with a history of nonresponding anti-tubercular therapy, revealed mucocutaneous lesions on examination. Fungating vocal cord lesions were visualized on bronchoscopy, raised suspicion of carcinoma. The second case, a 22-year-old female, referred to hospital with suspected vasculitis, with complaints of "off and on" fever with decreased oral intake, arthralgia, who later developed generalized nodular skin eruptions. On investigation, human immunodeficiency virus test was found to be negative in both the cases. Histopathological findings of skin biopsy, adrenal and bone marrow aspirates raised suspicion, whereas fungal cultures confirmed Histoplasma infection. Although diagnosis was delayed, but both of them were successfully treated with amphotericin B. PMID- 27688461 TI - Hyaline Fibromatosis Syndrome: A Rare Inherited Disorder. AB - Hyaline fibromatosis syndrome (HFS) is rare autosomal recessive disease characterized by the deposition of amorphous hyaline material in skin and visceral organs. It represents a disease spectrum with infantile systemic hyalinosis (ISH) being the severe form and juvenile hyaline fibromatosis (JHF) being the mild form. Dermatologic manifestations include thickened skin, perianal nodules, and facial papules, gingival hyperplasia, large subcutaneous tumors on the scalp, hyperpigmented plaques over the metacarpophalangeal joints and malleoli, and joint contractures. ISH shows a severe visceral involvement, recurrent infections, and early death. We report a case of 2.5-year-old female patient who presented with HFS who had overlapping features of both ISH and JHF. To the best of our knowledge, very few cases of HFS have been reported in Indian literature till date. PMID- 27688462 TI - Borderline Tuberculoid Leprosy Associated with Histoid Leprosy.

AB - A 34-year-old male came with complaints of multiple firms to hard nontender, nonitchy nodules, measuring 2 cm * 2 cm to 1 cm * 1.5 cm, present predominantly over the lower limbs. This condition started 5 years back as a single nodule over the thigh but gradually increased in number and size with time to involve both lower limbs. A differential diagnosis of cutaneous lymphoma and dermatofibroma was considered. He underwent a biopsy and immunohistochemistry for the same which were consistent with hemosiderotic histiocytoma and positive for vimentin. The patient was advised surgical excision for the same. The occurrence of multiple dermatofibromas although rare has been reported in a few case reports; however, the occurrence of multiple dermatofibromas of the hemosiderotic variant has not been documented yet. PMID- 27688464 TI - Generalized Morphea following Radiotherapy for an Intracranial Tumor. AB - Morphea is a localized scleroderma variety which can be circumscribed or generalized and is characterized by sclerotic plaques developing on trunk and limbs. Surgery and radiation have been implicated as etiological factors for the development of morphea. Majority of the radiation-induced morphea cases have occurred in patients with breast cancer. The affected areas have been generally restricted to the area of radiation and nearby surrounding area in most of the reported cases. We hereby report a case of a 27-year-old male who developed radiation-induced progressive generalized morphea after getting radiotherapy for an intracranial tumor. His condition improved after dexamethasone cyclophosphamide pulse therapy. With increased incidence of cancer worldwide and radiotherapy as a modality of treatment, it is imperative to follow the patient and look for the development of morphea which itself is a debilitating disease.

PMID- 27688469 TI - Optical Imaging of Ionizing Radiation from Clinical Sources. AB - Nuclear medicine uses ionizing radiation for both in vivo diagnosis and therapy. Ionizing radiation comes from a variety of sources, including x-rays, beam therapy, brachytherapy, and various injected radionuclides. Although PET and SPECT remain clinical mainstays, optical readouts of ionizing radiation offer numerous benefits and complement these standard techniques. Furthermore, for ionizing radiation sources that cannot be imaged using these standard techniques, optical imaging offers a unique imaging alternative. This article reviews optical imaging of both radionuclide- and beam-based ionizing radiation from high-energy photons and charged particles through mechanisms including radioluminescence, Cerenkov luminescence, and scintillation. Therapeutically, these visible photons have been combined with photodynamic therapeutic agents preclinically for increasing therapeutic response at depths difficult to reach with external light sources. Last, new microscopy methods that allow single-cell optical imaging of radionuclides are reviewed. PMID- 27688470 TI - NAMPT Inhibitor GMX1778 Enhances the Efficacy of 177Lu-DOTATATE Treatment of Neuroendocrine Tumors. AB - : Neuroendocrine tumors (NETs) can be treated by peptide receptor radionuclide therapy using radiolabeled somatostatin analogs. However, the efficacy of such treatment is low and needs to be optimized. Our study evaluated the potential radiosensitizing effects of inhibition of nicotineamide phosphoribosyltransferase on 177Lu-DOTATATE treatment in a NET model. METHODS: Nude mice xenografted with the human NET cell line GOT1 were treated with semiefficient doses of 177Lu DOTATATE (7.5 MBq, intravenously) or the nicotineamide phosphoribosyltransferase inhibitor GMX1778 (100 mg/kg/wk, orally). RESULTS: Median time to tumor progression (tumor volume larger than at day 0) was 3 d for controls, 7 d for single-dose GMX1778, 28 d for single-dose 177Lu-DOTATATE, 35 d for 3 weekly doses of GMX1778, and 98 d for combined treatment with 177Lu-DOTATATE and GMX1778 * 1. After 177Lu-DOTATATE and 3 weekly doses of GMX1778, none of the tumors progressed within 120 d. CONCLUSION: GMX1778 enhances the efficacy of 177Lu-DOTATATE treatment and induces a prolonged antitumor response. PMID- 27688472 TI - Evaluation of Spleen Glucose Metabolism Using 18F-FDG PET/CT in Patients with Febrile Autoimmune Disease. AB - The purpose of this study was to evaluate the clinical significance of 18F-FDG uptake by the spleen in patients with autoimmune disease. Methods: We retrospectively reviewed Severance Hospital's electronic medical records of patients hospitalized for the evaluation of fever who underwent 18F-FDG PET/CT. We found 91 patients with autoimmune diseases and 101 patients with localized infection. 18F-FDG uptake was assessed by measuring SUV in the spleen and liver. The spleen-to-liver ratio of the SUVmean (SLRmean) was calculated. Clinical and laboratory parameters were collected and evaluated for association with SLRmean In-hospital mortality was defined as all-cause mortality during hospital admission for fever. Results: SLRmean was significantly higher in autoimmune disease than in localized infectious disease (1.28 +/- 0.43 vs. 0.91 +/- 0.21, P < 0.001). In autoimmune disease, SLRmean was correlated with monocytes, aspartate aminotransferase, alanine aminotransferase, albumin, and ferritin. Analysis of receiver-operating-characteristic curves revealed that in comparison with laboratory parameters, SLRmean had the highest performance in differentiating autoimmune from localized infectious disease. Multivariate logistic regression analysis demonstrated that high SLRmean and low platelets were significantly associated with in-hospital mortality in febrile autoimmune disease. Conclusion: These findings suggest that spleen glucose metabolism is increased in febrile autoimmune disease. Spleen 18F-FDG uptake may provide information useful in differentiating febrile autoimmune disease from localized infectious disease and predicting clinical outcomes in febrile autoimmune disease. PMID- 27688473 TI - Repeatability of 18F-FLT PET in a Multicenter Study of Patients with High-Grade Glioma. AB - Quantitative 3'-deoxy-3'-18F-fluorothymidine (18F-FLT) PET has potential as a noninvasive tumor biomarker for the objective assessment of response to treatment. To guide interpretation of these quantitative data, we evaluated the repeatability of 18F-FLT PET as part of a multicenter trial involving patients with high-grade glioma. Methods:18F-FLT PET was performed on 10 patients with recurrent high-grade glioma at 5 different institutions within the Adult Brain Tumor Consortium trial ABTC1101. Data were acquired according to a double baseline protocol in which PET examinations were repeated within 2 d of each other with no intervening treatment. On each of the 2 imaging days, dedicated brain PET was performed at 2 time points, 1 and 3 h after 18F-FLT administration. Tumor SUVs and related parameters were measured at a central laboratory using various volumes of interest: isocontour at 30% of the maximum pixel (SUVmean_30%), gradient-based segmentation (SUVmean_gradient), the maximum pixel (SUVmax), and a 1-mL sphere at the region of highest uptake (SUVpeak). Repeatability coefficients (RCs) were calculated from the relative differences between corresponding SUV measurements obtained on the 2 d. Results: RCs for tumor SUVs were 22.5% (SUVmean_30%), 23.8% (SUVmean_gradient), 23.2% (SUVmax), and 18.5% (SUVpeak) at 1 h after injection. Corresponding data at 3 h were 22.4%, 25.0%, 27.3%, and 23.6%. Normalizing the tumor SUV data with reference to a background region improved repeatability, and the most stable parameter was the tumor-to-background ratio derived using SUVpeak (RC, 16.5%). Conclusion: SUV quantification of 18F-FLT uptake in glioma had an RC in the range of 18%-24% when imaging began 1 h after 18F-FLT administration. The volume-of-interest methodology had a small but not negligible influence on repeatability, with the best performance obtained using SUVpeak Although changes in 18F-FLT SUV after treatment cannot be directly interpreted as a change in tumor proliferation, we have established ranges beyond which SUV differences are likely due to legitimate biologic effects. PMID- 27688474 TI - Fission-Produced 99Mo Without a Nuclear Reactor. AB - 99Mo, the parent of the widely used medical isotope 99mTc, is currently produced by irradiation of enriched uranium in nuclear reactors. The supply of this isotope is encumbered by the aging of these reactors and concerns about international transportation and nuclear proliferation. Methods: We report results for the production of 99Mo from the accelerator-driven subcritical fission of an aqueous solution containing low enriched uranium. The predominately fast neutrons generated by impinging high-energy electrons onto a tantalum convertor are moderated to thermal energies to increase fission processes. The separation, recovery, and purification of 99Mo were demonstrated using a recycled uranyl sulfate solution. Conclusion: The 99Mo yield and purity were found to be unaffected by reuse of the previously irradiated and processed uranyl sulfate solution. Results from a 51.8-GBq 99Mo production run are presented. PMID- 27688475 TI - A Randomized Feasibility Study of 18F-Fluoroestradiol PET to Predict Pathologic Response to Neoadjuvant Therapy in Estrogen Receptor-Rich Postmenopausal Breast Cancer. AB - The aim of this study was to explore the ability of 18F-fluoroestradiol (18F-FES) PET/CT imaging to predict pathologic response to neoadjuvant therapy in postmenopausal women with estrogen receptor (ER)-rich breast cancer. Methods: This was a prospective, single-center study conducted as a substudy of the neoadjuvant study of chemotherapy versus endocrine therapy in postmenopausal patients with primary breast cancer (NEOCENT) trial. Patients with ER-rich breast cancer were randomized to neoadjuvant chemotherapy (NC) or neoadjuvant endocrine therapy (NET). The baseline SUVmax of 18F-FES PET/CT was measured. The pathologic response was assessed by the Miller-Payne system as nonresponse (grades 1 and 2) and response (grades 3-5). Results: Twenty-six patients were enrolled, with pathologic response achieved in 25 (NC, 12; NET, 13). Two patients achieved pathologic complete response after NC, but the remaining 23 patients had residual disease after NC or NET. Eight of 12 patients responded to NC, and 4 of 13 to NET; the difference was marginally significant (P = 0.07). In the NC group, the 2 patients with 18F-FES-negative tumors and none of the 10 patients with 18F-FES avid tumors achieved pathologic complete response (P = 0.02). No difference in the SUVmax between responders and nonresponders was observed in either group. However, 5 of 7 NC patients with a baseline SUVmax of less than 7.3 achieved pathologic response, whereas none of the 5 NET patients with an SUVmax of less than 7.3 were responders (P = 0.03). The SUVmax values of the NC group were negatively correlated with percentage reduction of tumor cellularity (r = -0.63, P = 0.03), whereas those of the NET group showed positive correlation (r = 0.62, P = 0.02). During the median follow-up of 74 mo (range, 44-85 mo), recurrence occurred in only 4 NET patients. In patients with an SUVmax of less than 7.3, recurrence occurred in none of the 8 NC patients and 2 of the 5 NET patients (P = 0.13). Conclusion: Postmenopausal women who are ER-positive, but 18F-FES negative, may benefit from NC rather than NET. 18F-FES PET/CT has the potential to predict response to neoadjuvant therapy in postmenopausal women with ER-rich breast cancer. PMID- 27688476 TI - Optimization of Image Reconstruction for 90Y Selective Internal Radiotherapy on a Lutetium Yttrium Orthosilicate PET/CT System Using a Bayesian Penalized Likelihood Reconstruction Algorithm. AB - Imaging on a gamma-camera with 90Y after selective internal radiotherapy (SIRT) may allow for verification of treatment delivery but suffers relatively poor spatial resolution and imprecise dosimetry calculation. 90Y PET/CT imaging is possible on 3-dimensional, time-of-flight machines; however, images are usually poor because of low count statistics and noise. A new PET reconstruction software using a Bayesian penalized likelihood (BPL) reconstruction algorithm (termed Q.Clear) was investigated using phantom and patient scans to optimize the reconstruction for post-SIRT imaging and clarify whether BPL leads to an improvement in clinical image quality using 90Y. Methods: Phantom studies over an activity range of 0.5-4.2 GBq were performed to assess the contrast recovery, background variability, and contrast-to-noise ratio for a range of BPL and ordered-subset expectation maximization (OSEM) reconstructions on a PET/CT scanner. Patient images after SIRT were reconstructed using the same parameters and were scored and ranked on the basis of image quality, as assessed by visual evaluation, with the corresponding SPECT/CT Bremsstrahlung images by 2 experienced radiologists. Results: Contrast-to-noise ratio was significantly better in BPL reconstructions when compared with OSEM in phantom studies. The patient-derived BPL and matching Bremsstrahlung images scored higher than OSEM reconstructions when scored by radiologists. BPL with a beta value of 4,000 was ranked the highest of all images. Deadtime was apparent in the system above a total phantom activity of 3.3 GBq. Conclusion: BPL with a beta value of 4,000 is the optimal image reconstruction in PET/CT for confident radiologic reading when compared with other reconstruction parameters for 90Y imaging after SIRT imaging. Activity in the field of view should be below 3.3 GBq at the time of PET imaging to avoid deadtime losses for this scanner. PMID- 27688477 TI - Cure of Human Ovarian Carcinoma Solid Xenografts by Fractionated alpha Radioimmunotherapy with 211At-MX35-F(ab')2: Influence of Absorbed Tumor Dose and Effect on Long-Term Survival. AB - The goal of this study was to investigate whether targeted alpha-therapy can be used to successfully treat macrotumors, in addition to its established role for treating micrometastatic and minimal disease. We used an intravenous fractionated regimen of alpha-radioimmunotherapy in a subcutaneous tumor model in mice. We aimed to evaluate the absorbed dose levels required for tumor eradication and growth monitoring, as well as to evaluate long-term survival after treatment. Methods: Mice bearing subcutaneous tumors (50 mm3, NIH:OVCAR-3) were injected repeatedly (1-3 intravenous injections 7-10 d apart, allowing bone marrow recovery) with 211At-MX35-F(ab')2 at different activities (close to acute myelotoxicity). Mean absorbed doses to tumors and organs were estimated from biodistribution data and summed for the fractions. Tumor growth was monitored for 100 d and survival for 1 y after treatment. Toxicity analysis included body weight, white blood cell count, and hematocrit. Results: Effects on tumor growth after fractionated alpha-radioimmunotherapy with 211At-MX35-F(ab')2 was strong and dose-dependent. Complete remission (tumor-free fraction, 100%) was found for tumor doses of 12.4 and 16.4 Gy. The administered activities were high, and long term toxicity effects (<=60 wk) were clear. Above 1 MBq, the median survival decreased linearly with injected activity, from 44 to 11 wk. Toxicity was also seen by reduced body weight. White blood cell count analysis after alpha radioimmunotherapy indicated bone marrow recovery for the low-activity groups, whereas for high-activity groups the reduction was close to acute myelotoxicity. A decrease in hematocrit was seen at a late interval (34-59 wk after therapy). The main external indication of poor health was dehydration. Conclusion: Having observed complete eradication of solid tumor xenografts, we conclude that targeted alpha-therapy regimens may stretch beyond the realm of micrometastatic disease and be eradicative also for macrotumors. Our observations indicate that at least 10 Gy are required. This agrees well with the calculated tumor control probability. Considering a relative biological effectiveness of 5, this dose level seems reasonable. However, complete remission was achieved first at activity levels close to lethal and was accompanied by biologic effects that reduced long-term survival. PMID- 27688478 TI - Hybrid Surgical Guidance: Does Hardware Integration of gamma- and Fluorescence Imaging Modalities Make Sense? AB - The clinically applied hybrid tracer indocyanine green-99mTc-nanocolloid enables combined radio- and fluorescence image guidance during sentinel node (SN) biopsy procedures. To provide optimal surgical guidance, this tracer requires the presence of both gamma- and fluorescence modalities in the operating room. We reasoned that the combination or integration of these modalities could further evolve the hybrid surgical guidance concept. To study this potential, we clinically applied 2 setups that included the combination of gamma-detection modalities and an open surgery fluorescence camera. Methods: To attach the fluorescence camera (VITOM) to either a gamma-ray detection probe (GP; VITOM-GP) or a portable gamma-camera (GC; Vitom GC), clip-on brackets were designed and printed in 3-dimensional sterilizable RC31. Both combined modalities were evaluated in, respectively, 5 and 6 patients with penile cancer during an SN biopsy procedure using indocyanine green-99mTc-nanocolloid. Intraoperatively, radio- and fluorescence-guided SN detection rates were scored at working distances of 0, 10, 20, and 30 cm for both combinations. Results: Using the VITOM GP combination, we evaluated 9 SNs. gamma-tracing rates were shown to be 100%, 88.9%, 55.6%, and 55.6% at a respective working distance of 0, 10, 20, and 30 cm. Detection rates for the fluorescence imaging-based detection were found to be 100%, 77.8%, and 77.8%, at respective working distances of 10, 20, and 30 cm. When the VITOM-GC setup was used, all 10 intraoperatively evaluated SNs could be visualized with the gamma-camera independent of the working distance. Fluorescence detection rates were 90%, 80%, and 80% at 10-, 20-, and 30-cm working distances. The integrated detection modalities were shown to work synergistically; overall the, GC was most valuable for rough localization (10- to 30-cm range) of the SNs, the GP for providing convenient real-time acoustic feedback, whereas fluorescence guidance allowed detailed real-time SN visualization. Conclusion: Our findings suggest that full integration of a fluorescence camera with gamma-detector (GP or GC) can be of value when a hybrid, radioactive and fluorescent tracer is used. PMID- 27688479 TI - 18F-FDG PET in Posterior Cortical Atrophy and Dementia with Lewy Bodies. AB - Posterior cortical atrophy (PCA) and dementia with Lewy bodies (DLB) have both been associated with occipital lobe hypometabolism on 18F-FDG PET, whereas relative sparing of posterior cingulate metabolism compared with precuneus/cuneus (i.e., cingulate island sign) is a feature of DLB. We aimed to determine whether patterns of hypometabolism or the cingulate island sign differed between PCA and DLB. Methods: Sixteen clinically diagnosed PCA and 13 probable DLB subjects underwent 18F-FDG PET. All PCA subjects showed beta-amyloid deposition on PET scanning. Regional hypometabolism was assessed compared with a control cohort (n = 29) using voxel- and region-level analyses in statistical parametric mapping. A ratio of metabolism in the posterior cingulate to precuneus plus cuneus was calculated to assess the cingulate island sign. In addition, the 18F-FDG PET scans were visually assessed to determine whether the cingulate island sign was present in each subject. Results: PCA and DLB showed overlapping patterns of hypometabolism involving the lateral occipital lobe, lingual gyrus, cuneus, precuneus, posterior cingulate, inferior parietal lobe, supramarginal gyrus, striatum, and thalamus. However, DLB showed greater hypometabolism in the medial occipital lobe, orbitofrontal cortex, anterior temporal lobe, and caudate nucleus than PCA, and PCA showed more asymmetric patterns of hypometabolism than DLB. The cingulate island sign was present in both DLB and PCA, although it was more asymmetric in PCA. Conclusion: Regional hypometabolism overlaps to a large degree between PCA and DLB, although the degree of involvement of the frontal and anterior temporal lobes and the presence of asymmetry could be useful in differential diagnosis. PMID- 27688481 TI - Quantitative Accuracy and Lesion Detectability of Low-Dose 18F-FDG PET for Lung Cancer Screening. AB - Lung cancer remains responsible for more deaths worldwide than any other cancer, but recently there has been a significant shift in the clinical paradigm regarding the initial management of subjects at high risk for this disease. Low dose CT has demonstrated significant improvements over planar x-ray screening for patient prognoses and is now performed in the United States. Specificity of this modality, however, is poor, and the additional information from PET has the potential to improve its accuracy. Routine screening requires consideration of the effective dose delivered to the patient, and this work investigates image quality of PET for low-dose conditions, in the context of lung lesion detectability. Reduced radiotracer doses were simulated by randomly discarding counts from clinical lung cancer scans acquired in list-mode. Bias and reproducibility of lesion activity values were relatively stable even at low total counts of around 5 million trues. Additionally, numeric observer models were developed and trained with the results of 2 physicians and 3 postdoctoral researchers with PET experience in a detection task; detection sensitivity of the observers was well correlated with lesion signal-to-noise ratio. The models were used prospectively to survey detectability of lung cancer lesions, and the findings suggested a lower limit around 10 million true counts for maximizing performance. Under the acquisition parameters used in this study, this translates to an effective patient dose of less than 0.4 mSv, potentially allowing a complete low-dose PET/CT lung screening scan to be obtained under 1 mSv. PMID- 27688480 TI - Associations Between Somatic Mutations and Metabolic Imaging Phenotypes in Non Small Cell Lung Cancer. AB - PET-based radiomics have been used to noninvasively quantify the metabolic tumor phenotypes; however, little is known about the relationship between these phenotypes and underlying somatic mutations. This study assessed the association and predictive power of 18F-FDG PET-based radiomic features for somatic mutations in non-small cell lung cancer patients. Methods: Three hundred forty-eight non small cell lung cancer patients underwent diagnostic 18F-FDG PET scans and were tested for genetic mutations. Thirteen percent (44/348) and 28% (96/348) of patients were found to harbor epidermal growth factor receptor (EGFR) or Kristen rat sarcoma viral (KRAS) mutations, respectively. We evaluated 21 imaging features: 19 independent radiomic features quantifying phenotypic traits and 2 conventional features (metabolic tumor volume and maximum SUV). The association between imaging features and mutation status (e.g., EGFR-positive [EGFR+] vs. EGFR-negative) was assessed using the Wilcoxon rank-sum test. The ability of each imaging feature to predict mutation status was evaluated by the area under the receiver operating curve (AUC) and its significance was compared with a random guess (AUC = 0.5) using the Noether test. All P values were corrected for multiple hypothesis testing by controlling the false-discovery rate (FDRWilcoxon, FDRNoether) with a significance threshold of 10%. Results: Eight radiomic features and both conventional features were significantly associated with EGFR mutation status (FDRWilcoxon = 0.01-0.10). One radiomic feature (normalized inverse difference moment) outperformed all other features in predicting EGFR mutation status (EGFR+ vs. EGFR-negative, AUC = 0.67, FDRNoether = 0.0032), as well as differentiating between KRAS-positive and EGFR+ (AUC = 0.65, FDRNoether = 0.05). None of the features was associated with or predictive of KRAS mutation status (KRAS-positive vs. KRAS-negative, AUC = 0.50-0.54). Conclusion: Our results indicate that EGFR mutations may drive different metabolic tumor phenotypes that are captured in PET images, whereas KRAS-mutated tumors do not. This proof-of-concept study sheds light on genotype-phenotype interactions, using radiomics to capture and describe the phenotype, and may have potential for developing noninvasive imaging biomarkers for somatic mutations.

AB - A practical and convenient procedure for the nucleophilic aromatic substitution of aryl fluorides and chlorides with dimethylamine was developed using a hydroxide assisted, thermal decomposition of N,N-dimethylforamide. These conditions are tolerant of nitro, nitrile, aldehyde, ketone, and amide groups but will undergo acyl substitution to form amides for methyl esters and acyl chlorides. Isolated yields of the products range from 44 - 98%, with the majority being greater than 70% for seventeen examples. PMID- 27688485 TI - Opposites Detract. PMID- 27688483 TI - A Long-lived Mouse Lacking Both Growth Hormone and Growth Hormone Receptor: A New Animal Model for Aging Studies. AB - Disruption of the growth hormone (GH) signaling pathway promotes insulin sensitivity and is associated with both delayed aging and extended longevity. Two kinds of long-lived mice-Ames dwarfs (df/df) and GH receptor gene-disrupted knockouts (GHRKO) are characterized by a suppressed GH axis with a significant reduction of body size and decreased plasma insulin-like growth factor-1 (IGF-1) and insulin levels. Ames dwarf mice are deficient in GH, prolactin, and thyrotropin, whereas GHRKOs are GH resistant and are dwarf with decreased circulating IGF-1 and increased GH. Crossing Ames dwarfs and GHRKOs produced a new mouse line (df/KO), lacking both GH and GH receptor. These mice are characterized by improved glucose tolerance and increased adiponectin level, which could imply that these mice should be also characterized by additional life span extension when comparing with GHRKOs and Ames dwarfs. Importantly, our longevity experiments showed that df/KO mice maintain extended longevity when comparing with N control mice; however, they do not live longer than GHRKO and Ames df/df mice. These important findings indicate that silencing GH signal is important to extend the life span; however, further decrease of body size in mice with already inhibited GH signal does not extend the life span regardless of improved some health-span markers. PMID- 27688486 TI - General Practice Forward View: a new charter for general practice? PMID- 27688482 TI - Impact of Aging on Proprioceptive Sensory Neurons and Intrafusal Muscle Fibers in Mice. AB - The impact of aging on proprioceptive sensory neurons and intrafusal muscle fibers (IMFs) remains largely unexplored despite the central function these cells play in modulating voluntary movements. Here, we show that proprioceptive sensory neurons undergo deleterious morphological changes in middle age (11- to 13-month old) and old (15- to 21-month-old) mice. In the extensor digitorum longus and soleus muscles of middle age and old mice, there is a significant increase in the number of Ia afferents with large swellings that fail to properly wrap around IMFs compared with young adult (2- to 4-month-old) mice. Fewer II afferents were also found in the same muscles of middle age and old mice. Although these age related changes in peripheral nerve endings were accompanied by degeneration of proprioceptive sensory neuron cell bodies in dorsal root ganglia (DRG), the morphology and number of IMFs remained unchanged. Our analysis also revealed normal levels of neurotrophin 3 (NT3) but dysregulated expression of the tyrosine kinase receptor C (TrkC) in aged muscles and DRGs, respectively. These results show that proprioceptive sensory neurons degenerate prior to atrophy of IMFs during aging, and in the presence of the NT3/TrkC signaling axis.

PMID- 27688518 TI - Identifying barriers to mental health help-seeking among young adults in the UK: a cross-sectional survey. AB - BACKGROUND: Despite the high prevalence and burden of mental health problems among young people, studies have suggested that they infrequently seek professional help. Understanding the barriers to help-seeking is an important step towards facilitating early access to mental health services and improving psychological wellbeing. AIM: To investigate why young adults may choose not to seek any support for an emotional or mental health difficulty. DESIGN AND SETTING: A cross-sectional online survey of young adults aged 18-25 from the general UK population. METHOD: The survey consisted of an anonymous questionnaire that measured psychological distress, help-seeking preferences, and barriers to accessing help, which included the Barriers to Access to Care Evaluation (BACE) scale and an open-ended question to explore reasons for not seeking help in the past. Qualitative feedback was analysed using thematic analysis. RESULTS: Overall, 35% of participants (n = 45) who reported having an emotional or mental health difficulty did not seek any formal or informal help. The thematic analysis revealed that stigmatising beliefs, difficulty identifying or expressing concerns, a preference for self-reliance, and difficulty accessing help were prominent barrier themes among responders. CONCLUSION: Young adults experiencing psychological distress may struggle to access help from others. Stigma and negative perceptions surrounding mental health and help-seeking may explain why young people are reluctant to approach others for help. Improving public awareness of the services and resources that are available, as well as screening for psychological distress in primary care services, may be necessary to improve mental wellbeing among young adults.

AB - To address shortcomings of purely reaction-time based attentional bias modification (ABM) paradigms, we developed an ABM task that is controlled by eye tracking. This task allows to assess and train both disengagement from negative pictures and maintained attention to positive pictures. As a proof-of-principle study with an unselected student sample, this positive training (PT; N = 44) was compared to a negative training (NT; N = 42), which reinforced the opposite attentional pattern. Importantly, training trials were completed only if participants performed the correct gaze patterns. Results showed that higher depression levels were associated with slower disengagement from negative stimuli at baseline. As expected, the PT induced longer fixations on positive pictures and faster disengagement from negative pictures. The NT showed no changes in attentional processes. The groups did not differ in mood reactivity and recovery from a stressor. Advantages of using eye-tracking in ABM and potential applications of the training are discussed. PMID- 27688523 TI - Multimodality pH imaging in a mouse dorsal skin fold window chamber model. AB - Upregulate levels of expression and activity of membrane H+ ion pumps in cancer cells drives the extracellular pH (pHe,) to values lower than normal. Furthermore, disregulated pH is indicative of the changes in glycolytic metabolism in tumor cells and has been shown to facilitate extracellular tissue remodeling during metastasis Therefore, measurement of pHe could be a useful cancer biomarker for diagnostic and therapy monitoring evaluation. Multimodality in-vivo imaging of pHe in tumorous tissue in a mouse dorsal skin fold window chamber (DSFWC) model is described. A custom-made plastic window chamber structure was developed that is compatible with both imaging optical and MR imaging modalities and provides a model system for continuous study of the same tissue microenvironment on multiple imaging platforms over a 3-week period. For optical imaging of pHe, SNARF-1 carboxylic acid is injected intravenously into a SCID mouse with an implanted tumor. A ratiometric measurement of the fluorescence signal captured on a confocal microscope reveals the pHe of the tissue visible within the window chamber. This imaging method was used in a preliminary study to evaluate sodium bicarbonate as a potential drug treatment to reverse tissue acidosis. For MR imaging of pHe the chemical exchange saturation transfer (CEST) was used as an alternative way of measuring pHe in a DSFWC model. ULTRAVIST(r), a FDA approved x-ray/CT contrast agent has been shown to have a CEST effect that is pH dependent. A ratiometric analysis of water saturation at 5.6 and 4.2 ppm chemical shift provides a means to estimate the local pHe. PMID- 27688522 TI - Fostering Higher Education: A Postsecondary Access and Retention Intervention for Youth with Foster Care Experience. AB - Most youth in foster care aspire to obtain higher education, but face daunting obstacles in doing so. While societal interest and effort to support foster youth in achieving higher education has grown, very few supports have evidence to show that they are effective at improving postsecondary outcomes. In an effort to address the dearth of clearly articulated, evidence-based postsecondary support approaches for foster youth, we have developed Fostering Higher Education (FHE), a comprehensive, structured, and evaluable postsecondary access and retention intervention composed of elements (professional educational advocacy, substance abuse prevention, mentoring) that are either evidence based or promising based on the scientific literature and their ability to address the outcomes of interest. This paper describes the development and youth usability and practitioner feasibility testing of the FHE intervention approach, which was developed through funding from the National Institute on Drug Abuse. Youth usability feedback was primarily positive, with the majority of participants indicating they found the FHE activities interesting and useful, and were comfortable participating in them. Practitioner feasibility feedback was also primarily positive, with almost unanimous ratings of the FHE intervention components as very important to provide to youth and that all would be feasible for an organization to implement, though the mentoring components were seen as slightly less feasible than other components. Next steps and implications of this intervention development process are discussed. PMID- 27688524 TI - TaqI, FokI, and ApaI Polymorphisms in the Vitamin D Receptor in Behcet's Disease in Turkish Population. AB - Objectives. In our study we aimed to determine VDR gene polymorphisms in patients with Behcet's disease (BD) and neuro-Behcet's disease (NBD) in Turkish population. Methods. PBL obtained from 37 patients with BD, 21 patients with NB, and 30 healthy controls were investigated. Genomic DNA was extracted from whole blood using the QIAamp Blood Kit. VDR ApaI (rs7975232), VDR FokI (rs2228570), and VDR TaqI (rs731236) genotyping was performed by real-time polymerase chain reaction with SimpleProbe melting-curve analysis. Results. The allelic and genotype distributions of FokI and TaqI polymorphisms were not different among Behcet's disease, neuro-Behcet's disease, and control subjects in Turkish population (p > 0.05). Only the frequency of ApaI A allele in control is higher than that in BD (60% versus 38.5%), and the p value is 0.014, but the power is not enough to conclude that ApaI A allele is protective in BD in our study. Taken together, we found no significant differences between the BD, NBD, and control groups regarding the distribution of ApaI, TaqI, and FokI genotype and alleles frequencies. Conclusions. Future studies with larger patients' numbers may show differences between VDR polymorphisms and Behcet's disease. PMID- 27688525 TI - Four Lymphomas in 1 Patient: A Unique Case of Triple Composite Non-Hodgkin Lymphoma Followed by Classical Hodgkin Lymphoma. AB - Composite lymphomas consist of 2 or more distinct lymphomas occurring in a single anatomical site or simultaneously in different sites and can be composed of any combination of B-cell non-Hodgkin lymphoma (NHL), T-cell NHL, or Hodgkin lymphoma (HL). Cases of composite lymphomas with more than 2 lymphomas are extremely rare, with only 4 reports in the literature. We report the case of a 49-year-old man with a triple composite lymphoma in a single lymph node, consisting of small lymphocytic lymphoma, follicular lymphoma, and mantle cell lymphoma in situ. The patient received multiple courses of chemotherapy and an autologous stem cell transplant, which resulted in complete remission. Then, 6 years after the stem cell transplant, he developed classical HL. This unique case is, to our knowledge, the first report of a patient with triple composite lymphoma consisting of 3 small mature B-cell NHLs, who subsequently developed a fourth lymphoma. PMID- 27688526 TI - Gender-Role Portrayals in Television Advertising Across the Globe. AB - Although there are numerous studies on gender-role portrayals in television advertising, comparative designs are clearly lacking. With content analytical data from a total of 13 Asian, American, and European countries, we study the stereotypical depiction of men and women in television advertisements. Our sample consists of 1755 ads collected in May 2014. Analyzing the gender of the primary character and voiceover, as well as the age, associated product categories, home- or work setting, and the working role of the primary character, we concluded that gender stereotypes in TV advertising can be found around the world. A multilevel model further showed that gender stereotypes were independent of a country's gender indices, including Hofstede's Masculinity Index, GLOBE's Gender Egalitarianism Index, the Gender-related Development Index, the Gender Inequality Index, and the Global Gender Gap Index. These findings suggest that gender stereotyping in television advertising does not depend on the gender equality prevalent in a country. The role of a specific culture in shaping gender stereotypes in television advertising is thus smaller than commonly thought. PMID- 27688528 TI - The Need to Change. PMID- 27688527 TI - The Relationship Between Endorsement of the Sexual Double Standard and Sexual Cognitions and Emotions. AB - Sexual gender norms promoting sexual prowess for men, but sexual modesty for women have been shown to negatively affect sexual and mental health in both men and women. Knowledge about the relationship between gender norms and sexual cognitions and emotions might further the understanding of continued gender-norm conformity. In the present study, we investigated whether and how gendered sexual attitudes are related to (positive and negative) sex-related emotions, via sexual cognitions (autonomy, body esteem, and approach/avoidance motives for sex). A survey was submitted to 293 heterosexually identified, sexually active, Dutch (central and southern regions) 18-25 year-olds. Results from a moderated mediation model (using structural equation modeling) revealed that women, but not men, who more strongly endorsed traditional gender-related sexual attitudes experienced significantly less positive and more negative emotions, as a result of decreased sexual autonomy and sexual body esteem as well as increased avoidance motives for sex. We conclude that, as a result of negative cognitions associated with the endorsement of traditional gender norms, women in particular are at risk of experiencing negative emotional outcomes in the sexual context. We argue that sexual cognitions and emotions deserve explicit attention in sex positive and gender-transformative sexuality education, which has been proven to be a vital resource for achieving increased gender-equity in sexual and romantic relationships. PMID- 27688529 TI - Parathyroid Neoplasms: The Army Hospital (Research & Referral) Experience. AB - BACKGROUND: Neoplasms of the parathyroid are common but parathyroid carcinoma is exceptionally rare. In contrast to most other malignant endocrine tumours that are usually less hormonally active, malignant parathyroid tumours are hyper functional. Malignant parathyroid tumours pose a diagnostic dilemma for the pathologist. OBJECTIVE: To study the clinicopathological profile of a case series of parathyroid neoplasms and determine features which facilitate a malignant diagnosis. METHODS: A retrospective analysis of seven cases of surgically treated parathyroid tumours over a three-year period at a single centre was done. Clinical, haematological, biochemical, and radiological data was accrued from medical records. The histopathology slides were reviewed along with the clinicopathological profile in an attempt to delineate markers of malignancy. RESULTS: Patients ranged from 30 to 58 years of age. Males and females were approximately equal. Weakness and bone pain were the commonest presenting symptoms. Over 50% had significant hypercalcaemia and all had elevated serum parathormone. Clinically apparent mass was seen in only one. All tumours were successfully localised using CT scan and MRI. Thick fibrous capsule and broad septal fibrosis was seen in both the carcinomas; these were thin in the adenomas. Mitotic counts of 1-3 per high power field (HPF), capsular invasion and nodal metastasis were noted in the malignant tumours. CONCLUSION: Elevated serum calcium and parathormone values point to a parathyroid neoplasm. Current imaging modalities are successful in localising the tumour preoperatively. Markedly elevated serum calcium, broad fibrous bands, mitotic counts and capsular invasion are indicators of malignancy. PMID- 27688530 TI - Detection of Human Immunodeficiency Virus Type 1 (HIV-1) A/AE Circulating Recombinant Form (CRF) in India: Possible Implications. AB - BACKGROUND: Rapidly evolving viruses such as human immunodeficiency virus (HIV-1) develop marked sequence differences in their genome over the course of an epidemic and in individuals infected for longer duration. This is because of the error prone reverse transcriptase (RT), which rapidly incorporates mutations resulting in genomic diversity, altered cell tropism, immune escape, and variable resistance to antiretroviral drugs. As a result, radically different genomic combinations may be generated in individuals infected by genetically diverse viruses that have mosaic genomes. METHODS: Whole blood sample was collected from 25 HIV-1 infected patients. Chromosomal DNA was isolated from the patient's peripheral blood mononuclear cells (PBMCs). Full-length gag gene (~1.5 kb) was amplified. PCR products were subjected to direct automated sequencing. For identification of recombinants Simplot version 2.5 was used. RESULTS: Out of 25 gag genes that were sequenced, the gene amplified from a 29 years old HIV-1 seropositive male revealed a putative recombinant sequence. This sequence showed maximum homology with HIV-1 subtype A. Simplot analysis revealed the sequence to be a likely recombinant with the following composition: Initial stretch of 1 to 200 nucleotides representing AE circulating recombinant form (CRF), 201 to 440 nucleotides representing HIV-1 subtype A, 441 to 660 nucleotides representing AE CRF again, 661 to 700 nucleotides representing HIV-1 subtype A and the remaining stretch of the nucleotides from 701 to 1076 representing AE CRF. CONCLUSION: We document a putative HIV-1 subtype A/ AE CRF. It is important to monitor various CRFs that are being generated and horizontally spread in the community. This has significant implications for development of candidate vaccine for India. PMID- 27688531 TI - Hepatitis G Virus Infection in Healthy Individuals, Acute Viral Hepatitis and Persons at Risk for Parenteral Transmission. AB - BACKGROUND: Hepatitis G virus (HGV), transmitted mostly by parenteral route, has been under investigation for its role as an agent for viral hepatitis. This study was carried out to find out the prevalence of HGV in healthy individuals, multi transfused patients with acute viral hepatitis and those under going dialysis. METHOD: The study included 200 healthy individuals and 180 patients, comprising acute viral hepatitis (100 cases), multi-transfused patients (50 cases) and patients undergoing dialysis (30 cases). HGV RNA and Hepatitis C virus (HCV) RNA was detected by reverse transcription and polymerase chain reaction (RT-PCR) in all. Viral marker studies for hepatitis A, B and E were carried out by ELISA in acute viral hepatitis cases. In healthy individuals, in patients with multiple transfusions or those undergoing dialysis, marker studies for HBV and HCV were carried out. RESULT: The prevalence of HGV in healthy individuals was 2.5% (5/200), in non A-E hepatitis 3% (3/100), in multi-transfused patients 4% (2/50) and in patients undergoing dialysis 6.67% (2/30). There was no significant difference in the prevalence rate of HGV infection in healthy individuals and in patients with non A-E hepatitis. CONCLUSION: Depending on prevalence rate, HGV could not be implicated as cause of acute viral hepatitis. Persons with parenteral risk factor (multiple blood transfusions and those undergoing dialysis) had higher prevalence rate as compared to healthy individuals. PMID- 27688532 TI - Resistance to Antituberculosis Drugs in Pulmonary Tuberculosis. AB - BACKGROUND: Incidence of drug resistance and pattern of susceptibility to antitubercular drugs in pulmonary tuberculosis amongst soldiers and their families was studied for four years at a military hospital in northwest India. METHODS: Identification and susceptibility tests were carried out as per procedures laid out in laboratory manual of Tuberculosis Research Centre (TRC), Chennai. RESULTS: Of the 172 strains of Mycobacterium tuberculosis (MTB) isolated from sputum samples, 150 (87.21%) were sensitive and 22 (12.79%) showed resistance to one or more antitubercular drugs. Acquired drug resistance was observed in 7 (31.82%) and primary drug resistance in 15 (68.18%) cases. Among 22 drug resistant cases, who were on short course chemotherapy (SCC), resistance to single drug was observed in 12 (54.54%), two drugs in 7 (31.82%) and to three or more drugs in 3 (13.64%) isolates. Fourteen (18.14%) strains were resistant to Streptomycin, 8 (4.65%) to Rifampicin, 11 (6.40%) to Isoniazid, 1 (0.58%) to Pyrazinamide and 2 (1.16%) to Ethambutol. Multidrug resistance was observed in 5 (2.91%) cases, of which resistance to Isoniazid and Rifampicin was present in 2 (1.16%) and their combination with other drugs in other 3 (1.74%) isolates. CONCLUSIONS: Drug susceptibility pattern to antitubercular drugs is discussed and compared with studies from other centres. PMID- 27688533 TI - Socio Behavioural Profile of HIV Positive DSC Personnel. AB - BACKGROUND: Few human immunodeficiency virus (HIV) positive Defence Security Corps (DSC) personnel reported for surveillance at one of the Air Force (AF) stations in 1992 and it was appropriate to study socio-behavioural profile of HIV positive DSC personnel to determine the reason for their vulnerability. METHOD: The study was conducted among 46 HIV positive DSC personnel during 1992-2004 at various AF stations. Pretested questionnaires were introduced to the subjects to ascertain their demographic, social, educational and behavioural profile vis-a vis their HIV-AIDS awareness. RESULTS: Majority of the subjects detected during pre-donation screening were middle aged, rural, semiliterate, (56.5%) and acquired the disease through heterosexual (95.66%) mode, mostly from commercial sex workers (CSWs). All were aware of HIV-AIDS prevention and most of them (77.2%) stated that condoms were easily available but 70.7% did not use the same for the fear of failure to perform under the influence of liquor. 74% subjects were found complying with medical instructions. CONCLUSION: The study brings out a discernable gap between the knowledge and practice of safe sex. Adequate preventive knowledge did not always result in practice of safe sex. PMID- 27688534 TI - Epidemiological Investigation of an Outbreak of Viral Hepatitis. AB - BACKGROUND: There was a rise in the number of viral hepatitis cases in a regimental training centre in Mar 2003 and an epidemic of viral hepatitis was suspected. METHODS: The clinical case sheets and preliminary investigations carried out in the local military hospital (MH) were reviewed. A cross sectional descriptive epidemiological study was undertaken with survey odf the suspected sewage and water pipelines. RESULTS: A total of 36 cases occurred from Mar 2003 to Apr 2003. There was clustering in time and space suggesting common source epidemic. All the 36 serum samples tested for IgM anti HEV antibodies were positive. Exploration of the water pipelines revealed sewage contamination due to leakage in the pipeline passing close to the sewage line. The overall attack rate was 1.44%. CONCLUSION: The outbreak of viral hepatitis in the regimental training centre occurred due to sewage contamination of drinking water pipeline. PMID- 27688535 TI - HIV Prevention in the Armed Forces: Perceptions and Attitudes of Regimental Officers. AB - BACKGROUND: Involvement of commanders and regimental officers is believed essential for a successful human immunodeficiency virus (HIV) infection prevention programme in the armed forces. METHODS: A structured questionnaire was sent to 40 different Information, Education and Communication (IEC) nodes to elicit the perception and attitude of regimental officers/commanders. From each station, 40 regimental officers/commanders were randomly selected and information from 1002 valid and completed questionnaires was analysed. RESULTS: Less than 50% could correctly assess the burden of HIV/AIDS in the armed forces. Only 41.19% felt HIV/AIDS is a problem serious enough to adversely affect operational efficiency. Majority had communicated with the troops on the subject of HIV/AIDS. The perceived threat of HIV being a problem in own unit was low. Though condom was often advocated, the felt need of condom in the unit was not commensurate with this advocacy. There were statistically significant differences in the perception and attitude among the three services. Only 7.08% of the officers emphasised the need of maintaining confidentiality while dealing with a HIV positive soldier. CONCLUSION: Energetic advocacy on HIV prevention including condom promotion involving the regimental officers is indicated. Wider dissemination of surveillance figures generated at AIDS Control Organisation (ACO) is needed for apprising them about the menace of HIV in the armed forces. PMID- 27688536 TI - Study of Behaviour Problems in a Paediatric Outpatient Department. AB - BACKGROUND: Behaviour problems in children still needs precise definition, explicit criterion and assessment on multiple paradigms. METHODS: Fifty children of the age group 6-14 years, from paediatric outpatient department, selected after randomisation were assessed for behaviour problems with the child behaviour checklist. The data collected was analysed using appropriate statistical tests. RESULTS: 40% children were above cutoff score. Mean child behaviour check list (CBCL) score was 40.6. Total of 72% children were from armed forces background of whom 9% were siblings of officers. 30.6% children from the armed forces background were above the cutoff score. There was no significant difference in the behaviour problems between different age groups and sex. There was no significant difference in behaviour problems between children of officers, other ranks or various income groups. Female children had behaviour problems like "too concerned with neatness or cleanliness", "feels has to be perfect" and "argues a lot" where as male children had behaviour problems like "Does not feel guilty after misbehaving", "argues a lot" and "restless". CONCLUSION: Behaviour problems in the subjects were externalizing ones. No specific trend was found in children of defence personnel vis-a-vis children of civilian population. PMID- 27688537 TI - Outbreak of Scrub Typhus in Jammu - A Report. AB - BACKGROUND: Jammu is scrub typhus prone. Scrub typhus is often seen when troops move out of permanent locations. METHODS: In a prospective study cases of fever reporting to the local military hospital from July to October 2002 were examined clinically, investigated and categorised as scrub typhus when Weil Felix readings were above 1:160. RESULTS: Twelve cases of scrub typhus were diagnosed during the period of study. The clinical features included fever, malaise and conjunctival congestion. However rashes were rare and only one had an eschar. Multisystem complications occurred in one patient. There was a spatial and temporal clustering of cases. Control of outbreak was carried out by 25% benzyl benzoate impregnation of clothing, clearing of scrub, residual spray with malathion and antirodent measures. CONCLUSION: Scrub typhus outbreaks have been noted whenever troops move out of permanent locations to scrub areas. PMID- 27688539 TI - Transfusion Transmitted Infections in Armed Forces: Prevalence and Trends. AB - BACKGROUND: This study presents data on the prevalence rate of infectious markers among voluntary and replacement donors in the blood transfusion service in Armed Forces from 2000 to 2004. METHODS: 39,646 units of blood were collected from donors during the period from 2000 to 2004. All the samples were screened for hepatitis B surface antigen (HBsAg), human immunodeficiency virus (HIV) 1&2, hepatitis C virus (HCV), and by venereal disease research laboratory test (VDRL). RESULTS: 24,527 (61.9%) were voluntary donations and 15,119 (38.1%) replacement donations. Prevalence of HBsAg had decreased, amongst voluntary donors from 1.67% to 0.77% but the positivity rate has not showed significant change. Seropositivity of HIV had decreased both in voluntary and replacement donors to 0.22% and 0.86% respectively. The seropositivity for anti-HCV showed steady decrease amongst voluntary donors from 0.46% to 0.20% in 2004, but in replacement donors, there was an increase in reactivity rate from 0.43% to 0.65%. CONCLUSION: The increased seropositivity for HCV, HIV and HBsAg could be decreased by introduction of nucleic acid amplification testing (NAT) in minipools for HCV and HIV and introduction of anti-HBcAg (IgM) for hepatitis B virus (HBV) infection. But this may not be possible in near future in developing countries due to financial constraints. At present implementation of strict donor criteria and with use of sensitive laboratory screening tests it is possible to reduce the incidence of transfusion transmitted infections (TTI) in Indian scenario. PMID- 27688538 TI - Cutaneous Tuberculosis : A Clinico-morphological Study. AB - BACKGROUND: Cutaneous tuberculosis forms a small subset of extrapulmonary tuberculosis. The present study is an attempt to observe the clinico morphological pattern seen in cases of cutaneous tuberculosis over a period of 5 years, and to correlate them with mantoux reactivity and human immunodeficiency virus (HIV) status. METHODS: All cases of cutaneous tuberculosis observed among the dermatology in patients and those attending out patient department were included in the study. The basis of diagnosis was clinical, histopathological and microbiological. Intradermal mantoux test and serological test in the form of enzyme-linked immunosorbent assay (ELISA) for tuberculosis was done. HIV screening was carried out in 32 cases. CD4 counts were done in all HIV positive cases. RESULTS: A total 0.02% patient attending the dermatology centre had cutaneous tuberculosis. The spectrum of infection included 19 (51%) cases of lupus vulgaris, 7 (19%) cases of papulonecrotic tuberculids, six cases each of tuberculosis verrucosa cutis and scrofuloderma. One case had scrofuloderma and lupus vulgaris and another both scrofuloderma and papulonecrotic tuberculide. One case of lichen scrofulosorum was seen in a seven year old boy. 11 cases revealed evidence of systemic tuberculosis. Seven cases of HIV with CD4 counts between 50 500 cells/MUl were observed in this study. PMID- 27688540 TI - Medical Abortion-An Alternative to Surgical Abortion. AB - BACKGROUND: Termination of early pregnancy has traditionally been done surgically, but agents are now available which can terminate pregnancy if taken orally, vaginally or parenterally. We have used a combination of mifepristone and misoprostol for termination of early pregnancy. MATERIAL AND METHOD: Fifty patients having amenorrhoea of upto 56 days with confirmed intrauterine pregnancy, were selected for medical termination of pregnancy. The patients were given tablet mifepristone (200mg) on day 1 and tablet misoprostol (400mcg) on day 3. On day 14, an ultrasound was done to confirm complete abortion. RESULT: Majority 35 (70%) patients had amenorrhoea between 40 - 50 days. The duration of bleeding was less than 5 days in 12%, between 5 -10 days in 56%, 10 -13 days in 16% and greater than 14 days in 16%. In all patients with bleeding of more than 14 days ultrasonography confirmed intrauterine products & a suction evacuation was done. In this series there were no failures. CONCLUSION: The combination of mifepristone and misoprostol is an effective method for termination of early pregnancy up to 56 days of amenorrhoea. PMID- 27688541 TI - Efficacy of Nebulised Epinephrine versus Salbutamol in Hospitalised Children with Bronchiolitis. AB - BACKGROUND: The use of bronchodilators in bronchiolitis lacks consensus. The efficacy of nebulised epinephrine versus salbutamol in bronchiolitis and the safety profile of the bronchodilators was studied. METHODS: Effects of nebulised epinephrine and salbutamol were compared in children with moderate to severe acute bronchiolitis. Thirty children between 2 to 24 months of age were recruited, 15 in each treatment group. Children received periodic (0,30,60 minutes followed by 4 hourly) doses of either 1:1000 laevo- epinephrine (0.5ml/kg subject to a maximum of 2.5ml with 3ml saline) or salbutamol (0.15mg/kg with 3ml saline) via nebuliser with oxygen. Changes in heart rate (HR), respiratory rate (RR), respiratory distress assessment instrument (RDAI), oxygen saturation (SpO2), oxygen requirement, duration of hospital stay and the side effects were studied. RESULTS: The respiratory status was better with significant improvement in RR, RDAI score and SpO2, decreased oxygen requirement and shorter hospital stay in the epinephrine group. There were no significant side effects in either group. CONCLUSION: Nebulised epinephrine is a useful and safe drug for moderate/severe bronchiolitis and is superior to salbutamol. PMID- 27688542 TI - Lymphatic Filariasis in India : Problems, Challenges and New Initiatives. AB - Filariasis is a major public health problem in India and inspite of existence of the National Filaria Control Programme since 1955, currently there may be up to 31 million microfilaraemics, 23 million cases of symptomatic filariasis, and about 473 million individuals potentially at risk of infection. Over the last 10 years advances have led to new diagnostic/ treatment tools and control strategies for filariasis. The new control strategy aims at transmission control through mass treatment and at disease control through individual patient management. As a signatory to 50(th) World Health Assembly resolution on global elimination of lymphatic filariasis in 1997, revised filariasis control program was launched in India in 13 districts in seven endemic states where mass drug administration was undertaken. Single dose mass administration annually in combination with other techniques has already eliminated lymphatic filariasis from Japan, Taiwan, South Korea and Solomon Islands and markedly reduced the transmission in China. Very high treatment coverage (probably > 85%) is required to achieve interruption of transmission and elimination in India. Hence, there is an urgent need for effective drug delivery strategies that are adapted to regional differences. This requires powerful advocacy tools and strategies as well as procedures for monitoring and evaluating the impact of elimination programme. PMID- 27688543 TI - Problems in Diagnosis of HIV Infection in Babies. AB - Serological diagnosis of human immunodeficiency virus (HIV) infection in babies born to HIV infected mothers is difficult because of presence of maternal anti HIV antibody up to 18 months. Conventional enzyme-linked immunosorbent assay (ELISA) and western blot may be positive in un-infected cases. Various other modalities which have been adopted include detection of HIV specific IgA, IgM, IgE, detection of p24 antigen, viral culture and detection of HIV nucleic acid by polymerase chain reaction (PCR). Viral culture or PCR positivity within first 48 hours of life indicates intrauterine infection. An early diagnosis of HIV infection in babies born to HIV infected mothers is essential as definite antiretroviral therapy (ART) can be instituted and unnecessary toxicity of drug therapy avoided if found negative. Though viral culture and DNA-PCR has sensitivity of >95% after one month of age, some cases can not be diagnosed during this period. Other tests like viral RNA detection by reverse transcription polymerase chain reaction (RT-PCR) and combination of tests will be required. PMID- 27688544 TI - Partner Counselling and Referral Services (PCRS) for HIV in Armed Forces - Visiting a Blind Spot. AB - The Indian armed forces have over 5000 cases of human immunodeficiency virus (HIV) infection since 1990. The spouses of the affected soldiers are at a constant risk of contracting infection if not informed of their husband's HIV status. The onus of counselling the spouse has been delegated to the commanding officer (CO) of the soldier as per policy. The spouses usually reside at their hometown away from the soldier's unit and bridging this "geographical discordance" and offering effective counselling becomes a tricky issue for the commanding officer (CO). This article examines the effectiveness of this strategy as practised in Indian armed forces. PMID- 27688545 TI - Ultrasound Guided Central Venous Cannulation.

PMID- 27688562 TI - Effects of Low Dose Vasopressin in Catecholamine Resistant Septic Shock. AB - BACKGROUND: Septic shock commonly leads to death in critically ill patients. Severe hypotension resistant to conventional catecholamine leads to multiorgan failure. We studied the effectiveness of low dose vasopressin in resistant septic shock. METHODS: Thirty critically ill patients with catecholamine resistant hypotension were included in the study. After adequate fluid resuscitation, infusion of norepinephrine and dobutamine was started. If the patient remained hypotensive, vasopressin was infused at a fixed rate of 0.04 unit/minute for 24 hours. Haemodynamic parameters and mortality rates were recorded. RESULT: There was a significant improvement in systolic and mean arterial pressure within four hours of starting vasopressin. This improvement continued throughout the 24-hour period. In addition, it was possible to withdraw dopamine in all the patients and significantly reduce infusion rates of dobutamine and norepinephrine. No significant complication was noted. CONCLUSION: Low dose vasopressin at the rate of 0.04 unit/minute is an effective vasopressor in adult patients with catecholamine resistant septic shock. PMID- 27688563 TI - Awake Craniotomy for Tumour Excision. AB - BACKGROUND: Craniotomy and excision of tumours can produce neurological deficits if the tumour is located close to eloquent areas of the brain. One technique of overcoming this problem is to keep the patient 'awake' during surgery. METHODS: Eight patients with intra cranial space occupying lesions (ICSOL) were operated 'awake', using a combination of skull block with sedation and analgesia. A mixture of 0.125% bupivacaine and 0.5% lignocaine was used for various nerve and field blocks. Midazolam, fentanyl and propofol in titrated doses were used to achieve conscious sedation. RESULT: The procedure was successful in all the patients. They tolerated the procedure well and were able to follow the commands intraoperatively as desired. There were no significant complications. CONCLUSION: Awake craniotomy with skull blocks with sedation and analgesia is a well established procedure. It requires a good rapport between surgeon, anaesthesiologist and the patient. PMID- 27688564 TI - Spectrum of Haemoglobinopathies in a Tertiary Care Hospital of Armed Forces. AB - BACKGROUND: Thalassaemia and other structural haemoglobinopathies are the major genetic disorders prevalent in certain parts of the world including India. This study presents the pattern of haemoglobinopathies amongst the referred patients of anaemia in a two-year period. METHODS: A total of 1032 patients were studied during a two-year period for anaemia investigation. Haematological indices, sickling test and haemoglobin electrophoresis with quantification of the bands was done in all cases. RESULT: Out of 1032 cases, 774 (75%) were normal and 258 (25%) cases had abnormal haemoglobin pattern. Of the 258 abnormal cases, 136 (53%) were males and 122 (47%) were females. Of all cases of anaemia 370 (36%) were microcytic hypochromic, 237 (23%) macrocytic, 151 (15%) were dimorphic and the rest (26%) had normocytic normochromic picture. 82% of microcytic hypochromic anaemias had reduced serum iron and elevated total iron binding capacity (TIBC), whereas 85% had decreased serum ferritin levels. Spectrum of haemoglobinopathies prevalent were beta-Thalassemia trait (17%), followed by sickle cell trait (2.3%). Other haemoglobinopathies in descending order of frequency were sickle cell disease (1.7%), Hb D trait (1%), Hb E trait (0.8%), sickle cell - beta thalassemia, Hb E disease, E - beta thalassemia (0.6% each) and thalassemia major (0.4%). CONCLUSION: This study provides a comprehensive database on the spectrum of haemoglobinopathies in the Armed Forces. It is suggested that detection of HbA2 should be carried out in all the high-risk groups with anaemia. PMID- 27688565 TI - Management of Nucleus and IOL Drop. AB - BACKGROUND: Thirty six cases of lenticular nucleus drop following phacoemulsification and 43 cases of posterior dislocation of intraocular lens (IOL) inclusive of two paediatric cases were managed by a modified vitrectomy procedure without using perfluorocarbon liquid (PFCL). METHODS: In these cases the incision was placed inferotemporally at pars plana. The limbal sites of the earlier cataract surgery were utilised as the other two ports. In either case adequate vitrectomy was performed first. In cases of nuclear drop, the nucleus was impaled (speared) with a micro vitreo retinal blade and brought into the anterior chamber from where it was delivered out. In cases of IOL drop the same was picked up by an intra-vitreal forceps. RESULT: Of the 77 adult cases treated 57 (74%) of the eyes had a visual recovery of 6/18 or more. CONCLUSION: Prompt surgical management in cases of nuclear drop or posterior dislocation of IOL yields good results. PMID- 27688566 TI - Risk Factors for Coronary Artery Disease in Indians. AB - BACKGROUND: A case control study was carried out to study the emerging risk factors for coronary artery disease in Indians. METHODS: The diagnosis of coronary artery disease was based on correlation of clinical, biochemical, electrocardiography, echocardiography, treadmill testing and coronary arteriography findings. The study comprised 100 cases of coronary artery disease (acute coronary syndrome and chronic coronary artery disease) and 100 controls in two tertiary care service hospitals. The subjects were evaluated for total plasma homocysteine, insulin, C-reactive protein (CRP), lipoprotein fibrinogen and anti chlamydial anti-bodies. RESULT: Male to female ratio was 10:1 in study group with similar predominance of males in controls. Mean age of the cases was 47 years (range 25-59 years) and that of controls was 43 years (range 23-56 years). 64% cases had acute coronary syndrome and 34% had chronic coronary artery disease. In the coronary artery disease population, 76% cases had hyperhomocyteinemia, 9% hyperinsulinaemia, 11% abnormal CRP values, 23% abnormal lipoprotein (a) levels, 40% IgG anti-chlamydial anti-bodies and only 11% had Ig M anti-chlamydial antibodies. In the control population, 72% had hyperhomocystinaemia and 6% hyperinsulinaemia while 23% and 9% controls had IgG and IgM anti chlamydial antibodies respectively. In control group 19% cases had abnormal lipoprotein(a) levels and only 2% had abnormal C reactive protein values. Significant correlation of CAD was seen with CRP values and Ig G anti-chlamydial antibodies. Both the study group and controls had higher homocysteine levels than that observed in some Indian and Western studies. CONCLUSION: High C reactive protein levels and Ig G anti-chlamydial antibodies are associated with coronary artery disease in Indians. Insulin, lipoprotein A, fibrinogen, lgM anti-chlamydial antibodies and higher levels of total plasma homocysteine have no significant association with coronary artery disease. PMID- 27688567 TI - Use of Anti-Craving Agents in Soldiers with Alcohol Dependence Syndrome. AB - BACKGROUND: In a search for an effective 'anti-alcohol pill', three modern anti craving agents have been studied in alcoholics of Army/ DSC, Air Force, Navy and Coast Guard. METHODS: 129 patients of alcohol dependence syndrome were randomly assigned to three groups where topiramate, acamprosate and naltrexone were used as anti-craving agents in a year long prospective study. Of these 92 patients completed the study. RESULT AND CONCLUSION: Topiramate (76.3%) appears to be significantly more effective (p<0.01) in sustaining abstinence, though naltrexone (57.7%) and acamprosate (60.70%) offer moderate relapse-prevention efficacy. Side effects of all the three agents have been mild, transient and self-limiting. We recommend a trial of topiramate, before invaliding out of any alcoholic soldier. PMID- 27688568 TI - Comparative Study of Recovery after Sevoflurane versus Halothane Anaesthesia in Adult Patients. AB - BACKGROUND: Induction and maintenance characteristics of sevoflurane and halothane have been studied, but little work has been done to compare the postoperative recovery of these two agents. METHODS: Sixty adult, ASA I and II patients were allocated randomly into Group A and Group B of 30 each. Group A received sevoflurane and Group B received halothane for maintenance. At the end of surgery early recovery, intermediate recovery and discharge criteria were assessed. RESULTS: Early recovery assessed with the mean time to extubation was 6.7 +/- 2.29 min in Group A and 9.07 +/- 1.64 min in Group B; eye opening was 7.28 +/- 2.3 min in Group A and 10.6 +/- 1.77 min in Group B; response to verbal command was 8.52 +/- 2.83 min in Group A and 12.33 +/- 2.17 min in Group B, while orientation was 10.43 +/- 3.15 min in Group A and 14.77 +/- 2.66 min in Group B. These differences were statistically significant (p<0.001). The mean time to reach post anaesthesia care unit discharge criteria was shorter for Group A (21.1 +/- 4.69 min) as compared to Group B (27.43 +/- 6.51 min) and this difference was statistically significant (p<0.001). CONCLUSION: Early recovery time and time taken to achieve discharge criteria were faster with sevoflurane. PMID- 27688569 TI - Antibody to Hepatitis B Surface Antigen in Vaccinated Health Care Workers. AB - BACKGROUND: Health care workers (HCWs) in Armed Forces are immunised against Hepatitis B virus (HBV), however they are not subjected to anti-HBs (antibody to Hepatitis B surface antigen) assessment after primary vaccination. The present study was undertaken to determine the protection offered by HBV vaccine in HCW. METHODS: Cross-sectional study was carried out at tertiary care hospital. A total 146 HBV vaccine compliant HCW were evaluated for quantitative anti-HBs by enzyme immune assay. RESULT: 129 (88.4%) subjects had protective levels of anti-HBs. Higher age at vaccination was an important risk factor in low vaccine response. Decline in anti-HBs with time was evident. Anti-HBs levels were more than 10mIU/ml in subjects even after 11 years of primary vaccination. There was no difference in protection in booster and non booster groups. CONCLUSION: Age is the most important factor in HBV vaccine response. Booster dose of HBV vaccine is not necessary in healthy HCW for atleast ten years after primary vaccination. The study recommends early primary vaccination of HCW and 'initial' anti-HBs assay for confirmation of vaccine response. PMID- 27688571 TI - Conjunctival-Limbal Autograft for Primary and Recurrent Pterygium. AB - BACKGROUND: It has been postulated that pterygium results from hypo function of limbal stem cells. Therefore conjunctival-limbal autograft has been advocated for the treatment of this condition. This study was undertaken to evaluate the results of conjunctival-limbal autograft procedure in primary and recurrent pterygia. METHODS: 32 eyes of 28 individuals with primary and recurrent pterygium (24 primary, 8 recurrent) were undertaken for conjunctival-limbal autograft procedure under peribulbar anaesthesia followed by topical antibiotic- steroid drops for two weeks. The cases were reviewed as per protocol for 6 to 18 months. RESULT: There was no recurrence of pterygium in these cases and they were free from any major postoperative complications. CONCLUSION: Conjunctival-limbal autograft is the procedure of choice for primary and recurrent pterygia. PMID- 27688570 TI - Dengue: A Clinicohaematological Profile. AB - BACKGROUND: Fifty cases of fever, clinically suspected to be dengue were studied. METHODS: Complete clinical, haematological evaluation and IgM capture assay was done. RESULT: 54% of patients clinically suspected to have dengue were positive for IgM antibodies by enzyme-linked immunosorbent assay (ELISA). The commonest clinical feature was fever with rash (85%). Thrombocytopenia was seen in 19% of patients only. One patient died of dengue shock syndrome (DSS). CONCLUSION: Out of the 27 cases of seropositive dengue there was one death due to dengue shock syndrome. Thrombocytopenia may not always be a feature of dengue. PMID- 27688572 TI - Chlamydia trachomatis Infection and Photosensitive Dermatoses. AB - BACKGROUND: Photosensitivity to Chlamydia trachomatis has been described in almost 50% of chronic cases of lymphogranuloma venereum (LGV) caused by L1, L2 or L3 serovars. Photosensitivity in non LGV strains of C trachomatis has not been studied. We studied the association of various photosensitive dermatoses with C trachomatis infection in non LGV cases. METHODS: Sera of all the cases of photosensitivity, melasma, chronic actinic dermatitis (CAD), polymorphic light eruption (PLE), actinic prurigo (AP) and rosacea were tested for the presence of IgM, IgG and IgA antibodies to C trachomatis by ELISA method. The results were compared with 30 healthy controls. RESULT: Seventeen (25.53%) of 57 cases of photosensitivity as against two (6.67%) controls were seropositive for IgM/IgG/IgA antibodies, a statistically significant difference (chi(2) 6.18, p 0.013). Similarly, significantly higher seropositivity was observed in 12 (25.53%) of 47 cases of melasma (chi(2) 4.38, p 0.0363) and six (46.15%) of 13 cases with CAD (chi(2) 6.91, p 0.0086). Although higher proportion of patients of rosacea [five (31.25%) of 16 cases] and PLE [four (25.0%) of 16 cases] were seropositive, the difference was not statistically significant (chi(2) 3.23, p >0.05, OR 6.36, CI 95% 0 to 48 and chi(2) 3.09, p 0.078, OR 4.67, CI 95% 5 to 41 respectively). There was no association of AP. CONCLUSION: The observations suggest that C trachomatis infection in non LGV cases is an important cause of PS, melasma and CAD. It appears to be an important cause of rosacea and PLE. We recommend that all cases of photosensitivity, melasma, CAD, PMLE and rosacea and their spouses/sexual contacts be investigated for C trachomatis infection. PMID- 27688573 TI - Cholestasis of Pregnancy : A Prospective Study. AB - BACKGROUND: Intrahepatic cholestasis of pregnancy (ICP) typically occurs during the last trimester of gestation. The most accurate marker for diagnosis and follow-up of ICP is increased total bile acid levels (above 11.0 micro mol/L) [1]. ICP is a benign disease with no consequences to the mother but it is associated with an increased rate of fetal morbidity and mortality. METHOD: A prospective study was carried out in 1500 deliveries which included 27 cases of ICP. The mode of delivery, complications and fetal outcome of intrahepatic cholestasis group were compared with rest of the deliveries. Cases having pruritic lesions of skin, viral hepatitis, gall stones, autoimmune liver diseases were excluded. Random selection of 300 pregnancies in the control group was done and their liver function tests were carried out for comparison. All the patients with cholestasis of pregnancy were treated with ursodeoxycholic acid. RESULT: The levels of the aminotransferases and alkaline phosphatase levels rose significantly (p < 0.05) in the study group. Cholestatic group did not have any significant difference in mode of delivery or fetal outcome from the control group. The patients in the study group were treated with ursodeoxycholic acid with significant relief in symptoms (p < 0.01), while improvement in serum bilirubin levels, alkaline phosphatase levels and aminotransferases levels were not statistically significant. CONCLUSION: In absence of serum bile acids levels, alkaline phosphatase and aminotransferases levels may help in diagnosis and management of cholestasis of pregnancy. Ursodeoxycholic acid treatment is effective in reducing the pruritus. PMID- 27688574 TI - Accidental Outbreak of Non-Bacterial Food Poisoning. AB - BACKGROUND: Troops deployed in isolated garrisons face erratic supply of rations. At times they resort to use of locally grown plants without knowledge of local flora, resulting in accidental food poisoning. METHODS: This is a descriptive, analytical and epidemiological study of one such outbreak of food poisoning, due to use of a locally grown plant as vegetable, amongst soldiers of a unit in high altitude. An epidemiological case sheet was made and food specific attack rates of those exposed and not exposed were calculated to identify the food item. The toxicological analysis of food item established the cause. RESULTS: Of the 39 people who consumed the meal, 29 fell ill with an attack rate of 74.35%. All the cases presented with classical features of atropine poisoning and were managed with sedatives, physostigmine and supportive care. Twenty one had symptoms severe enough to warrant hospitalization. All the cases made complete recovery. The attack rate for food item containing plant poison was 96.4%. The toxicological analysis of food sample established the presence of atropine alkaloids. The plant was identified on flowering as Atropa acuminata. CONCLUSION: An outbreak of non bacterial food poisoning in soldiers at high altitude, caused by accidental ingestion of a dish made out of Atropa acuminata plant leaves containing atropine related alkaloids was investigated and conclusively established. PMID- 27688575 TI - Body Mass Index and Obesity : Tailoring "cut-off" for an Asian Indian Male Population. AB - BACKGROUND: Obesity/overweight is a recognized risk factor for a host of disorders. The disease risk stratification is commonly based on the Quetelets Index (Body Mass Index- BMI), a surrogate measure of fatness. The currently used BMI cut-offs to classify people as overweight or obese in Armed Forces have been defined in studies on Caucasian populations. However, because of differences in body structure and composition in different ethnic, socioeconomic, cultural and regional groups the correspondence between BMI and body fat content varies between populations. We conducted this pilot study in the Indian Navy to define BMI cut-offs for overweight and obesity using body fat content derived from Skin Fold Thickness as the standard. MATERIAL AND METHODS: The study was conducted on 121 volunteers from a naval hospital staff in the age range of 18 to 47 years. The mean age, height, weight, BMI, body fat in the study group was 26.73 years (+/- 5.5098), 168.56 cm (+/- 6.1034), 65.92 Kg (+/- 10.2746), 23.17 Kg/m(2) (+/- 3.0265) and 19.91% (+/- 4.831) respectively. RESULTS: The prevalence of overweight/obesity was 20.66% by BMI and 47.11% by body fat content. Receiver operating characteristic (ROC) curve analysis defined a BMI of 23.85 kg/m(2) as the cut off for overweight with a sensitivity of 70.2% (95% CI 56.6 - 81.6) and 87.5% specificity (95% CI 76.8-94.4) and a BMI of 24.38 kg/m(2)with 90% sensitivity (95% CI 68.3-98.5) and 81.2% specificity (95% CI 72.2-88.3) for obesity. CONCLUSION: The results of our study suggest lower BMI cut offs for overweight and obesity in Indian populations than those recommended by WHO. PMID- 27688576 TI - Cerebral Venous Thrombosis.

PMID- 27688591 TI - Outcomes of keratoplasty in the mucopolysaccharidoses: an international perspective. AB - OBJECTIVE: To describe visual outcomes after penetrating keratoplasty and deep anterior lamellar keratoplasty in patients with mucopolysaccharidoses. METHODS: This is a retrospective review of keratoplasty in consecutive patients from Brazil, England, Finland, Germany, Portugal, Sweden and the USA. All patients had corneal clouding due to mucopolysaccharidoses. Preoperative and postoperative visual outcome and ocular comorbidities were identified. Success was arbitrarily defined as any improvement in visual acuity or best-corrected visual acuity better than logarithm of the minimum angle of resolution 0.30 (20/40). Statistical analysis included only data from first operated eyes in the 16 patients who underwent bilateral keratoplasty. RESULTS: Forty-eight eyes from 32 patients with mucopolysaccharidoses I, IV or VI are reported. Mean follow-up was 70 months (range: 5-186). Penetrating keratoplasty was performed in 45 eyes and deep anterior lamellar keratoplasty in 3 eyes. At last follow-up, a successful visual outcome for penetrating keratoplasty in first operated/only operated eyes was found in 63%. Rejection episodes occurred in 23% of grafts; however, a clear graft was recorded at last follow-up in 94%. Ocular pathway comorbidities were identified in 63% of eyes transplanted. CONCLUSIONS: Clear corneal grafts can be obtained for patients with corneal clouding due to mucopolysaccharidosis with improvement in visual acuity in the majority. PMID- 27688592 TI - Release of experimental retinal vein occlusions by direct intraluminal injection of ocriplasmin. AB - PURPOSE: Retinal vein occlusions (RVO) are a major cause of vision loss in people aged 50 years and older. Current therapeutic options limit the consequences of RVO but do not eliminate the cause. Cannulation of the involved vessel and removal of the clot may provide a more permanent solution with a less demanding follow-up. However, cannulation of smaller retinal veins remains challenging. This paper explores the use of ocriplasmin (recombinant plasmin without its kringles) to clear RVO, using a robotic micromanipulator. METHODS: Branch RVO were induced in a porcine model with rose bengal followed by 532 nm endolaser to the superior venous branch of the optic nerve. The vein was cannulated proximal to the occlusion or beyond the first branching vessel from the obstruction. The vein was infused with a physiologic citric acid buffer solution (CAM) or CAM/ocriplasmin. The time of cannulation, number of attempts, and the ability to release the thrombus were recorded. RESULTS: Cannulation and infusion was possible in all the cases. The use of a micromanipulator allowed for a consistent cannulation of the retinal vein and positional stability allowed the vein to remain cannulated for up to 20 min. In none of the attempts (5/5) with CAM did the thrombus dissolve, despite repeat infusion/relaxation cycles. In 7/7 injections of CAM/ocriplasmin near to the point of obstruction, the clot started to dissolve within a few minutes of injection. An infusion, attempted beyond the first venous branch point proximal to the clot, was unsuccessful in 2/3 attempts. CONCLUSIONS: Ocriplasmin is effective in resolving RVO if injected close to the site of occlusion with the use of a micromanipulator. PMID- 27688593 TI - Characteristics and variations of in vivo Schlemm's canal and collector channel microstructures in enhanced-depth imaging optical coherence tomography. AB - BACKGROUND/AIMS: To characterise in vivo Schlemm's canal (SC) and collector channels (CC) microstructures using enhanced-depth imaging (EDI) optical coherence tomography (OCT). METHODS: Serial horizontal EDI OCT B-scans (81 scans, 15*5 degrees rectangle) were prospectively obtained in the nasal and temporal limbus. SC cross-sectional area (CSA) was measured by delineating its lumen in each B-scan. CCs connected to SC were counted. SC CSA and the number of CCs were compared between the nasal and temporal areas. RESULTS: Eleven eyes (11 normal subjects) were included (mean age, 28+/-5 years). SC and CCs were clearly demarcated in EDI OCT B-scans with excellent repeatability and reproducibility (intraclass correlation coefficients, 0.830-0.886 and 0.793, respectively; all p<0.001). SC CSA varied considerably among subjects, ranging from 1664 to 6007 um2 (average, 3514+/-1235 um2), and among different regions of the same eye with coefficient of variation in each eye ranging from 23% to 46% (average, 32+/-7%). The number of CCs in the analysed area also varied considerably among subjects, ranging from 5 to 11 (average, 8.73+/-1.85). The mean SC CSA (3839+/-1402 um2 vs 3189+/-1209 um2; p=0.033) and number of CCs (5.5+/-1.4 vs 3.3+/-1.1; p=0.001) were significantly greater nasally than temporally. The mean SC CSA was significantly correlated with the number of CCs (r=0.635, p=0.036). CONCLUSIONS: High-quality images of the aqueous outflow pathway can be obtained with a clinical device, avoiding postacquisition processing. In vivo SC and CC microstructures vary considerably among individuals and regions. SC tends to be larger in regions with more CCs. PMID- 27688594 TI - The P1 biomarker for assessing cortical maturation in pediatric hearing loss: a review. AB - We review evidence for a high degree of neuroplasticity of the central auditory pathways in early childhood, citing evidence of studies of the P1 and N1 cortical auditory evoked potentials in congenitally deaf children receiving cochlear implants at different ages during childhood, children with auditory neuropathy spectrum disorder and children with hearing loss and comorbid multiple disabilities. We discuss neuroplasticity, including cortico-cortical de-coupling and cross-modal re-organization that occurs in deafness. We provide evidence for the clinical utility of the P1 cortical auditory evoked potential (CAEP) as a non invasive biomarker that can be used to objectively assess maturation of auditory cortex in clinical cases of cochlear implant patients and candidates. Finally, we present clinical case studies in which the P1 CAEP biomarker proved useful in clinical decision-making regarding intervention in cases of single-sided deafness, auditory neuropathy spectrum disorder, mild hearing loss and hypoplastic auditory nerve. PMID- 27688595 TI - Finding a Life Worth Living: Meaning in Life and Graduation from College. AB - Graduation from college is an important milestone for young adults, marked by mixed emotions and poignancy, and therefore is an especially salient context for studying meaning in life. The present research used experience-sampling methodology to examine the antecedents and consequences of students' experience of meaning in life over the course of graduation. Participants were 74 graduating students who provided a total of 538 reports over the span of three days, including commencement day. Increased levels of state meaning in life during the days around commencement were linked to spending time with people in general and with family in particular, as well as thinking about one's years in college. Thinking about one's years in college mediated the effects of present company on state meaning in life. Graduates who experienced higher levels of state meaning in life during the days around their commencement ceremony had higher trait levels of meaning in life one week following commencement. We discuss how making meaning of a poignant experience has implications for healthy psychological development. PMID- 27688596 TI - A Biomass Flow Approach to Population Models and Food Webs. AB - The dominant differential equation paradigm for modeling the population dynamics of species interacting in the framework of a food web retains at its core the basic prey-predator and competition models formulation by Alfred J. Lotka (1880 1945) and Vito Volterra (1860-1940) nearly nine decades ago. This paradigm lacks a trophic-level-independent formulation of population growth leading to ambiguities in how to treat populations that are simultaneously both prey and predator. Also, this paradigm does not fundamentally include inertial (i.e. change resisting) processes needed to account for the response of populations to fluctuating resource environments. Here I present an approach that corrects both these deficits and provides a unified framework for accounting for biomass transformation in food webs that include both live and dead components of all species in the system. This biomass transformation formulation (BTW) allows for a unified treatment of webs that include consumers of both live and dead material both carnivores and carcasivores, herbivores and detritivores-and incorporates scavengers, parasites, and other neglected food web consumption categories in a coherent manner. I trace how BTW is an outgrowth of the metaphysiological growth modeling paradigm and I provide a general compact formulation of BTW in terms of a three-variable differential equation formulation for each species in the food web: viz. live biomass, dead biomass, and a food-intake-related measure called deficit-stress. I then illustrate the application of this new paradigm to provide insights into two-species competition in variable environments and discuss application of BTW to food webs that incorporate parasites and pathogens.

AB - Content-based medical image retrieval (CBMIR) is an active research area for disease diagnosis and treatment but it can be problematic given the small visual variations between anatomical structures. We propose a retrieval method based on a bag-of-visual-words (BoVW) to identify discriminative characteristics between different medical images with Pruned Dictionary based on Latent Semantic Topic description. We refer to this as the PD-LST retrieval. Our method has two main components. First, we calculate a topic-word significance value for each visual word given a certain latent topic to evaluate how the word is connected to this latent topic. The latent topics are learnt, based on the relationship between the images and words, and are employed to bridge the gap between low-level visual features and high-level semantics. These latent topics describe the images and words semantically and can thus facilitate more meaningful comparisons between the words. Second, we compute an overall-word significance value to evaluate the significance of a visual word within the entire dictionary. We designed an iterative ranking method to measure overall-word significance by considering the relationship between all latent topics and words. The words with higher values are considered meaningful with more significant discriminative power in differentiating medical images. We evaluated our method on two public medical imaging datasets and it showed improved retrieval accuracy and efficiency. PMID- 27688599 TI - Cognitive Impairment Involving Social Cognition in SPG4 Hereditary Spastic Paraplegia. AB - Objectives. To describe cognitive assessment including social cognition in SPG4 patients. Methods. We reported a series of nine patients with SPG4 mutation with an extensive neuropsychological examination including social cognition assessment. Results. None of our patients presented with mental retardation or dementia. All presented with mild cognitive impairment with a high frequency of attention deficit (100%), executive disorders (89%), and social cognition impairment (78%). An asymptomatic patient for motor skills presented with the same cognitive profile. No correlation was found in this small sample between cognitive impairment and motor impairment, age at disease onset, or disease duration. Conclusions. SPG4 phenotypes share some cognitive features of frontotemporal lobar degeneration and amyotrophic lateral sclerosis. Cognitive disorders including executive disorders and social cognition impairment are frequent in SPG4 patients and might sometimes occur before motor disorders. Therefore, cognitive functions including social cognition should be systematically assessed in order to improve the clinical management of this population. PMID- 27688600 TI - Doxycycline and Benznidazole Reduce the Profile of Th1, Th2, and Th17 Chemokines and Chemokine Receptors in Cardiac Tissue from Chronic Trypanosoma cruzi-Infected Dogs. AB - Chemokines (CKs) and chemokine receptors (CKR) promote leukocyte recruitment into cardiac tissue infected by the Trypanosoma cruzi. This study investigated the long-term treatment with subantimicrobial doses of doxycycline (Dox) in association, or not, with benznidazole (Bz) on the expression of CK and CKR in cardiac tissue. Thirty mongrel dogs were infected, or not, with the Berenice-78 strain of T. cruzi and grouped according their treatments: (i) two months after infection, Dox (50 mg/kg) 2x/day for 12 months; (ii) nine months after infection, Bz (3,5 mg/kg) 2x/day for 60 days; (iii) Dox + Bz; and (iv) vehicle. After 14 months of infection, hearts were excised and processed for qPCR analysis of Th1 (CCL2, CCL3, CCL4, CCL5, CXCL9, and CXCL11), Th2 (CCL1, CCL17, CCL24, and CCL26), Th17 (CCL20) CKs, Th1 (CCR5, CCR6, and CXCR3), and Th2/Th17 (CCR3, CCR4, and CCR8) CKR, as well as IL-17. T. cruzi infection increases CCL1, CCL2, CCL4, CCL5, CCL17, CXCL10, and CCR5 expression in the heart. Dox, Bz, or Dox + Bz treatments cause a reversal of CK and CKR and reduce the expression of CCL20, IL-17, CCR6, and CXCR3. Our data reveal an immune modulatory effect of Dox with Bz, during the chronic phase of infection suggesting a promising therapy for cardiac protection. PMID- 27688601 TI - Prospective Clinical Trial for Septic Arthritis: Cartilage Degradation and Inflammation Are Associated with Upregulation of Cartilage Metabolites. AB - Background. Intra-articular infections can rapidly lead to osteoarthritic degradation. The aim of this clinical biomarker analysis was to investigate the influence of inflammation on cartilage destruction and metabolism. Methods. Patients with acute joint infections were enrolled in a prospective clinical trial and the cytokine composition of effusions (n = 76) was analyzed. Characteristics of epidemiology and disease severity were correlated with levels of cytokines with known roles in cartilage turnover and degradation. Results. Higher synovial IL-1beta concentrations were associated with clinical parameters indicating a higher disease severity (p < 0.03) excluding the incidence of sepsis. Additionally, intra-articular IL-1beta levels correlated with inflammatory serum parameters as leucocyte counts (LC) and C-reactive protein concentrations (p < 0.05) but not with age or comorbidity. Both higher LC and synovial IL-1beta levels were associated with increased intra-articular collagen type II cleavage products (C2C) indicating cartilage degradation. Joints with preinfectious lesions had higher C2C levels. Intra-articular inflammation led to increased concentrations of typical cartilage metabolites as bFGF, BMP-2, and BMP 7. Infections with Staphylococcus species induced higher IL-1beta expression but less cartilage destruction than other bacteria. Conclusion. Articular infections have bacteria-specific implications on cartilage metabolism. Collagen type II cleavage products reliably mark destruction, which is associated with upregulation of typical cartilage turnover cytokines. This trial is registered with DRKS00003536, MISSinG. PMID- 27688602 TI - SP600125 Attenuates Nicotine-Related Aortic Aneurysm Formation by Inhibiting Matrix Metalloproteinase Production and CC Chemokine-Mediated Macrophage Migration. AB - Nicotine, a major chemical component of cigarettes, plays a pivotal role in the development of abdominal aortic aneurysm (AAA). c-Jun N-terminal kinase (JNK) has been demonstrated to participate in elastase-induced AAA. This study aimed to elucidate whether the JNK inhibitor SP600125 can attenuate nicotine plus angiotensin II- (AngII-) induced AAA formation and to assess the underlying molecular mechanisms. SP600125 significantly attenuated nicotine plus AngII induced AAA formation. The expression of matrix metalloproteinase- (MMP-) 2, MMP 9, monocyte chemoattractant protein- (MCP-) 1, and regulated-on-activation, normal T-cells expressed and secreted (RANTES) was significantly upregulated in aortic aneurysm lesions but inhibited by SP600125. In vitro, nicotine induced the expression of MCP-1 and RANTES in both RAW264.7 (mouse macrophage) and MOVAS (mouse vascular smooth muscle) cells in a dose-dependent manner; expression was upregulated by 0.5 ng/mL nicotine but strongly downregulated by 500 ng/mL nicotine. SP600125 attenuated the upregulation of MCP-1 and RANTES expression and subsequent macrophage migration. In conclusion, SP600125 attenuates nicotine plus AngII-induced AAA formation likely by inhibiting MMP-2, MMP-9, MCP-1, and RANTES. The expression of chemokines in MOVAS cells induced by nicotine has an effect on RAW264.7 migration, which is likely to contribute to the development of nicotine related AAA. PMID- 27688604 TI - Efficacy and safety of eribulin mesylate in advanced soft tissue sarcomas. AB - Despite recent advances in the field, treatment options for metastatic soft tissue sarcoma patients are limited. Eribulin, an antimitotic derived from the natural marine sponge product halichondrin B, is currently approved for the treatment of metastatic breast cancer. Following the promising activity of eribulin in sarcoma in a Phase II trial, the drug was recently compared to dacarbazine in pretreated advanced leiomyosarcoma (LMS) and liposarcoma (LPS) patients in a Phase III trial. Eribulin was associated with a significant 2-month improvement in median overall survival compared to dacarbazine (13.5 vs. 11.5 months, heart rate: 0.768) despite no documented significant difference in progression-free survival. In a subgroup analysis, the survival advantage associated with eribulin was evident in the LPS subgroup but not in the LMS subgroup. Following these encouraging results, the Food and Drug Administration has approved eribulin for the treatment of advanced LPS for patients who received prior anthracycline chemotherapy. In this short review, we will evaluate the evidence for eribulin in soft tissue sarcoma, highlight its mechanisms of action, and summarize the results of the major preclinical and clinical studies with a particular focus on the results of the Phase III trial. PMID- 27688605 TI - PET/CT in paediatric malignancies - An update. AB - (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a well established imaging modality in adult oncological practice. Its role in childhood malignancies needs to be discussed as paediatric malignancies differ from adults in tumor subtypes and they have different tumor biology and FDG uptake patterns. This is also compounded by smaller body mass, dosimetric restrictions, and physiological factors that can affect the FDG uptake. It calls for careful planning of the PET study, preparing the child, the parents, and expertise of nuclear physicians in reporting pediatric positron emission tomography/computed tomography (PET/CT) studies. In a broad perspective, FDG-PET/CT has been used in staging, assessment of therapy response, identifying metastases and as a follow up tool in a wide variety of pediatric malignancies. This review outlines the role of PET/CT in childhood malignancies other than hematological malignancies such as lymphoma and leukemia. PMID- 27688603 TI - Anti-Inflammation of Natural Components from Medicinal Plants at Low Concentrations in Brain via Inhibiting Neutrophil Infiltration after Stroke. AB - Inflammation after stroke consists of activation of microglia/astrocytes in situ and infiltration of blood-borne leukocytes, resulting in brain damage and neurological deficits. Mounting data demonstrated that most natural components from medicinal plants had anti-inflammatory effects after ischemic stroke through inhibiting activation of resident microglia/astrocytes within ischemic area. However, it is speculated that this classical activity cannot account for the anti-inflammatory function of these natural components in the cerebral parenchyma, where they are detected at very low concentrations due to their poor membrane permeability and slight leakage of BBB. Could these drugs exert anti inflammatory effects peripherally without being delivered across the BBB? Factually, ameliorating blood-borne neutrophil recruitment in peripheral circulatory system has been proved to reduce ischemic damage and improve outcomes. Thus, it is concluded that if drugs could achieve effective concentrations in the cerebral parenchyma, they can function via crippling resident microglia/astrocytes activation and inhibiting neutrophil infiltration, whereas the latter will be dominating when these drugs localize in the brain at a low concentration. In this review, the availability of some natural components crossing the BBB in stroke will be discussed, and how these drugs lead to improvements in stroke through inhibition of neutrophil rolling, adhesion, and transmigration will be illustrated. PMID- 27688606 TI - HIV-associated hematologic malignancies: Experience from a Tertiary Cancer Center in India. AB - CONTEXT AND AIM: Data on HIV associated hematologic malignancies is sparse from India. This study attempts to analyze the spectrum and features of this disease at a tertiary cancer center in India. SETTING AND METHODS: Retrospective study from case records of patients registered with a diagnosis of hematologic malignancy and HIV infection between January 2010 and June 2015. RESULTS: Thirteen cases of HIV associated hematologic malignancies were identified, six of them pediatric. HIV diagnosis was concurrent to diagnosis of cancer in 12 and preceded it in one of them. ECOG PS at presentation was >1 in all of them. All patients, except one, had B symptoms. Six of the patients had bulky disease and six are stage 4. Predominant extranodal disease was seen in 67% of them. NHL accounted for 10 of 13 patients and DLBCL-Germinal center was the most common subtype. Mean CD4+ cell count was 235/MUL (range, 32-494). HAART could be given along with chemotherapy to 11 patients. Two-thirds of patients received standard doses of therapy. Chemo-toxicity required hospitalization in 58%. CR was achieved in 45% and 36% had progressive disease with first-line therapy. At the time of last follow up, 3 patients were alive with responsive disease, 2 in CR and 1 in PR. None of the pediatric patients were long time responders. CONCLUSIONS: These malignancies were of advanced stage and higher grade. Goal of therapy, in the HAART era, is curative. Pediatric patients had dismal outcome despite good chemotherapy and HAART. There is an urgent need to improve data collection for HIV related cancers in India.

Lymphocyte-transforming viruses can directly infect lymphocytes, disrupt normal cell functions, and promote cell division. Epstein-Barr virus (EBV) is known to be associated with several lymphomas, especially Hodgkin lymphomas (HLs). And recently, the lymphocyte-transforming role of hepatitis B virus (HBV) has been emphasized. AIMS: The aim of this study was to elucidate the association of two potentially oncogenic, widely prevalent latent DNA viruses, EBV and HBV, in non HL (NHL). SETTINGS AND DESIGN: In this prospective study, we estimated plasma EBV and HBV DNA in NHL patients. MATERIALS AND METHODS: Peripheral blood was obtained from newly diagnosed, treatment na ive, histologically confirmed NHL patients. Plasma EBV DNA was quantified by real-time polymerase chain reaction (PCR) targeting Epstein-Barr Nucleic acid 1 while the plasma HBV DNA was detected using nested PCR targeting HBX gene. In a small subset of patients, follow-up plasma samples post-anticancer chemotherapy were available and retested for viral DNA. RESULTS: Of the 110 NHL patients, ~79% were B-cell NHL and ~21% were T-cell NHL. Plasma EBV-DNA was detected in 10% NHLs with a higher EBV association in Burkitt lymphoma (33.3%) than other subtypes. Pretherapy HBV DNA was detected in 21% NHLs; most of them being diffuse large B-cell lymphoma (DLBCL). Moreover, 42% of DLBCL patients had HBV DNA in plasma. Since all patients were HBV surface antigen seronegative at diagnosis, baseline plasma HBV-DNAemia before chemotherapy was indicative of occult hepatitis B infection. CONCLUSIONS: Our findings indicate a significant association of HBV with newly diagnosed DLBCL.

AB - BACKGROUND: Tobacco related cancers (TRC) account for major share of all cancers and updated of incidence data are helpful in policy changes. The aim was to present an update of TRCs on age-adjusted incidence data and corresponding lifetime risk of developing TRC for different regions of the country. METHODS: The data for this study were obtained from published reports of 25 population based cancer registries (PBCRs) in India. The PBCRs in different parts of India were divided into seven regions such as North, South, Central, Northeast, West, Rural West, and East. Data indicators such as age-adjusted rates (AARs) of incidence and the cumulative risks of TRCs up to the age of 64 years for each of the 10 TRC sites of either sex in each of 25 registries were obtained from the National Cancer Registry Programme reports. RESULTS: Among all TRCs, esophagus, lung, hypopharynx, and mouth are the leading sites for both males and females. Males in Northeast region had the highest risk 1 in 27 of developing esophageal cancer, 1 in 67 for cancer of lungs and hypopharynx, followed by 1 in 143 for both mouth and tongue cancers. Females also had the highest risk of esophagus and lungs (1 in 63 female) and cancer of mouth (1 in 250) in Northeast region. Proportion of TRC in comparison of all cancer ranged from 11-25% for men and 3 18% for women. CONCLUSIONS: Proportion of TRC in relation to all cancers was still high in different registries of India including the Northeast region. PMID- 27688609 TI - Evaluation of myeloid cells (tumor-associated tissue eosinophils and mast cells) infiltration in different grades of oral squamous cell carcinoma. AB - BACKGROUND: The multifunctional involvement and infiltration of myeloid cells (tumor-associated tissue eosinophils [TATE] and mast cells) can provide a unique opportunity to define relevant effectors functions that may represent novel, therapeutic options for modulation of tumor onset/growth. AIM: Our study aimed to evaluate infiltration of myeloid cells (TATE and Mast cells) infiltration in different grades (WHO grading) of oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS: Total 30 cases of OSCC were selected for this study. Hematoxylin and eosin stain and toluidine blue special stain, to evaluate TATE and the mast cells infiltration, were used. Three-year follow-up of OSCC cases was done. RESULT: Among 30 cases, 63.33% cases of OSCC showed TATE-positive and 36.66% cases showed TATE-negative. Regarding mast cells infiltration, 66.66% OSCC cases showed mast cells positive and 33.33% cases did not show significant mast cells infiltration. We found significant association of TATE and mast cells infiltration in OSCC cases. These myeloid cells infiltration significantly associated with age of patients but did not show any significant association with gender, site, and habit of cases. When we compared these cells infiltration with clinical stages and different histological grades of tumor, we found their infiltration is decreasing, from Stages 1 to Stage 3 of tumor and from well to poorly differentiated carcinoma. We have also found the less infiltration of these myeloid in recurrence cases of OSCC. CONCLUSION: As the infiltration of TATE and mast cells are correlated, along with evaluation of TATE, we should also evaluate the presence of mast cells infiltration in OSCC. The assessment of myeloid cells could become, in the future, useful for therapeutic approaches in this subset of the patient. PMID- 27688611 TI - Bloodstream infections in febrile neutropenic patients at a tertiary cancer institute in South India: A timeline of clinical and microbial trends through the years. AB - INTRODUCTION: Febrile neutropenia (FN) is an oncological emergency. The choice of empiric therapy depends on the locally prevalent pathogens and their sensitivities, the sites of infection, and cost. The Infectious Diseases Society of America guidelines are being followed for the management of FN in India. METHODS: This is a prospective observational study conducted at a tertiary care cancer centre from September 2012 to September 2014. OBJECTIVES: The objectives of this study were as follows: (1) To review the pattern of microbial flora, susceptibility pattern, and important clinical variables among bloodstream infections in febrile neutropenic patients with solid tumors and hematological malignancies. (2) As per the institutional protocol to periodically review the antibiotic policy and susceptibility pattern, and compare the findings with an earlier study done in our institute in 2010. This was a prospective study conducted from September 2012 to September 2014. RESULTS: About 379 episodes of FN were documented among 300 patients. About 887 blood cultures were drawn. Of these, 137 (15%) isolates were cultured. Isolates having identical antibiograms obtained from a single patient during the same hospitalization were considered as one. Hence, 128 isolates were analyzed. About 74 (58%) cultures yielded Gram negative bacilli, 51 (40%) were positive for Gram-positive cocci, and 3 (2%) grew fungi. Among Gram-negative organisms, Escherichia coli followed by Acinetobacter baumannii and Klebsiella pneumoniae accounted for 78% of the isolates. Among Gram positive cocci, Staphylococcus species accounted for 84% of the isolates. We have noted a changing trend in the antibiotic sensitivity pattern over the years. Following the switch in empirical antibiotics, based on the results of the study done in 2010 (when the empirical antibiotics were ceftazidime + amikacin), the sensitivity to cefoperazone-sulbactam has plunged from about 80% to 60%%. Similar reduction in susceptibility was noted for piperacillin-tazobactam, imipenem, and meropenem. On the contrary, there was a marked increase in sensitivity to ceftazidime (50-76%). Based on these results, we have reverted to ceftazidime + amikacin as the empirical antibiotics. CONCLUSION: Every institute must have a regular revision of antibiotic policy based on periodic assessment of the clinical and microbiological profile in FN. This will combat antibiotic resistance. PMID- 27688610 TI - Newly established stem cell transplant program: 100 days follow-up of patients and its comparison with published Indian literature. AB - BACKGROUND: Hematopoietic progenitor stem cell transplantation (HPSCT) is used as a standard treatment option to improve outcome in hematological and nonhematological disorders. It is important for new HPSCT program to look at its patient outcome data and compare it with the published data to evaluate the efficacy of program. AIMS: The aim was to compile and collate the patient outcome data of HPSCT and compare with published reports. MATERIALS AND METHODS: Patient demographics, indications, stem cell harvest by apheresis, dose collected, infusion, engraftment, and follow-up data were collected from hospital information system from 2010 to 2013 in a tertiary care hospital. HPSCs were mobilized with granulocyte colony-stimulating factor, and harvests were done on the 5(th) day. Engraftment was decided for neutrophil when counts were 0.5 * 10(9)/L and for platelets when counts were 20 * 10(9)/L on two consecutive days without any transfusion support. RESULTS: There were 133 harvests for 95 patients with various disorders; multiple myeloma was most common in autologous and acute lymphoblastic leukemia in allogeneic group. One hundred harvests were done for autologous and 33 for allogeneic HPSCT. In autologous group, of 66 patients, 60 (90.9%) received stem cell infusion at median dose of 4.63 * 10(6) CD34(+) cells/kg. Similarly, in allogeneic group, of 29 patients, 27 (93.10%) received infusion at median dose of 5.8 * 10(6) CD34(+) cells/kg. 58 (96.9%) patients and 25 (92.6%) engrafted in autologous and allogeneic group, respectively. The median time for neutrophils engraftment was 11 days in autologous group and 12 days in allogeneic group. The median time for platelet engraftment was 11.5 days in autologous group and 13 days in allogeneic group. The 100-day survival rate was 95% (n = 57) in autologous group and 77.8% (n = 21) in allogeneic group. CONCLUSION: This data analysis shows reasonably good results of HPSCTs with majority of patients surviving at 100-day follow-up. PMID- 27688612 TI - Quantification of telomerase activity in normal oral mucosal tissue and oral squamous cell carcinoma. AB - BACKGROUND AND OBJECTIVE: The role of telomeres and telomerase in oral cancer is an area of much recent interest. The understanding of the role of telomere biology, the end replication problem leading to genomic instability and the reactivation of telomerase, is absolutely critical to our understanding of oral cancer, and more so, to our ability of early diagnosis and developing novel therapies and cancer prevention approaches. The aim of the present study was to quantify telomerase activity (TA) in oral squamous cell carcinoma (OSCC) and normal oral mucosa and assess the role of telomerase as diagnostic and prognostic marker of oral malignancy. MATERIALS AND METHODS: We quantified TA in 45 patients with OSCC and 20 normal oral mucosal specimens using polymerase chain reaction based telomeric repeat amplification protocol assay and compared it with the clinical status and grade of malignancy. RESULTS: TA was detected in 89% of malignant and 5% of normal oral mucosal tissue. The TA levels ranged from 0.28 to 6.91 (mean 2.05, standard deviation [SD] 1.33) in OSCC and 0.21 to 1.09 (mean 0.54, SD 0.27) in normal oral mucosa. There was no relationship between TA levels and clinical stages, site of the lesion, history of adverse habits, or sex of the patient. However, under the WHO classification, there were significant differences (P < 0.00) between Grades I, II, and III. Furthermore, increasing age of the patient significantly correlated with TA. INTERPRETATION AND CONCLUSION: The results of the present study indicate that activation of TA is frequent in OSCC. Statistically significant difference in quantified telomerase levels of OSCC and normal oral mucosa (P < 0.00) demonstrates the significant clinical usefulness of telomerase activation as a valuable marker for diagnosis while significant correlation of TA with grades of malignancy indicates its effectiveness as marker for prognosis of OSCC. PMID- 27688614 TI - Intrathecal trastuzumab for leptomeningeal carcinomatosis in patients with human epidermal growth factor receptor 2 positive breast cancer. AB - There has been recent increase in incidence of leptomeningeal carcinomatosis, possibly due to widespread use of adjuvant trastuzumab and its known poor CNS penetration. Currently there are limited therapeutic options for these patients and outcome is poor. We report two cases of women with HER2 positive breast cancer who developed leptomeningeal carcinomatosis for which they were treated with intrathecal trastuzumab in combination with systemic therapy. Both patients had rapid symptomatic benefit and radiological response and remained progression free for at least seven months. Intrathecal trastuzumab can be considered a reasonable therapeutic option for these difficult to treat patients. PMID- 27688613 TI - Epidermal growth factor receptor mutation in adenocarcinoma lung in a North Indian population: Prevalence and relation with different clinical variables. AB - INTRODUCTION: Lung cancer is one of the most common causes of cancer deaths worldwide. Adenocarcinoma is taking over squamous cell lung cancer as the predominant histological subtype. Several cytotoxic drugs are available for the treatment of lung cancer, but side effects limit their use. Recently, targeted therapies for cancers have come into clinical practice. AIMS AND OBJECTIVES: To determine the prevalence of epidermal growth factor receptor (EGFR) mutation in adenocarcinoma lung in a North Indian population and its relation with different clinical variables. MATERIALS AND METHODS: A total of 57 patients who met inclusion criteria were recruited into the study. Relevant history, clinical examination and investigations were done. EGFR mutation was done in all patients. RESULTS: A total of twenty patients tested positive for EGFR mutation. EGFR was more frequently detected in female patients (53.8%), while as only 19.4% of the male patients expressed EGFR mutation, which was statistically very significant (P = 0.007). EGFR mutation was more frequently detected in nonsmokers (52%) as compared to smokers (21.9%) which also was statistically significant (P value of 0.018). EGFR mutation was more common in Stage III and IV adenocarcinomas (48%) as compared to Stage I and II (21.4%) which was statistically significant (P value 0.034). CONCLUSION: EGFR mutation should be routinely done in all patients of adenocarcinoma lung particularly non-smoker females with Stage III and IV disease.

We report a 52-year-old woman diagnosed to have FIGO Stage 1b, Grade 1 endometrioid adenocarcinoma, presenting with isolated distal humerus metastasis, 2 years after surgery and adjuvant radiotherapy for primary disease. Imaging, bone scintigraphy, and cytology confirmed the diagnosis of poorly differentiated metastatic adenocarcinoma. She was treated with local radiotherapy followed by six cycles of paclitaxel and carboplatin chemotherapy along with zoledronic acid, monthly. She is symptom-free after the treatment and at a first follow-up visit after 3 months. PMID- 27688616 TI - Early integration of palliative medicine into emergency care: Is it a feasible option. AB - Patients with advanced malignancy often experience symptoms of disease and treatment that contribute to distress and diminish their quality of life. Most of these patients present to the emergency department thus raising its importance in providing such care especially at the end of life situation. An approach that is aimed at controlling these symptoms, whether or not undergoing curative therapy, is a key feature of high-quality patient-centered care. This paper explores the potential role of palliative medicine in the emergency room and how early integration with emergency care can help improve the quality of life of patients and thus achieve better outcomes.

PMID- 27688620 TI - Developmental Defects Mediated by the P1/HC-Pro Potyviral Silencing Suppressor Are Not Due to Misregulation of AUXIN RESPONSE FACTOR 8. AB - Plant viral suppressors of RNA silencing induce developmental defects similar to those caused by mutations in genes involved in the microRNA pathway. A recent report has attributed viral suppressor-mediated developmental defects to up regulation of AUXIN RESPONSE FACTOR 8 (ARF8), a target of miR167. The key piece of evidence was that the developmental defects in transgenic Arabidopsis (Arabidopsis thaliana) expressing viral suppressors were greatly alleviated in the F1 progeny of a cross with plants carrying the arf8-6 mutation. Arf8-6 is a SALK line T-DNA insertion mutant, a class of mutations prone to inducing transcriptional silencing of transgenes expressed from the 35S promoter. We have reinvestigated the role of ARF8 in viral suppressor-mediated developmental defects, using two independent arf8 mutations and the P1/HC-Pro potyviral suppressor of silencing. Progeny of a cross between P1/HC-Pro transgenic Arabidopsis and the arf8-6 T-DNA insertion mutant showed little effect on the P1/HC-Pro phenotype in the F1 generation, but almost all arf8-6/P1/HC-Pro progeny had lost the phenotype in the F2 generation. However, the loss of phenotype in the F2 generation was not correlated with the number of functional copies of the ARF8 gene. Instead, it reflected transcriptional silencing of the P1/HC-Pro transgene, as evidenced by a pronounced decrease in P1/HC-Pro mRNA and the appearance of 35S promoter small interfering RNAs. Furthermore, an independent loss-of-function point mutation, Arf8-8, had no detectable effects on P1/HC-Pro phenotype in either the F1 or F2 generations. Together, these data argue against the previously reported role of increased ARF8 expression in developmental defects caused by P1/HC-Pro. PMID- 27688619 TI - Class II Cytochrome P450 Reductase Governs the Biosynthesis of Alkaloids. AB - Expansion of the biosynthesis of plant specialized metabolites notably results from the massive recruitment of cytochrome P450s that catalyze multiple types of conversion of biosynthetic intermediates. For catalysis, P450s require a two electron transfer catalyzed by shared cytochrome P450 oxidoreductases (CPRs), making these auxiliary proteins an essential component of specialized metabolism. CPR isoforms usually group into two distinct classes with different proposed roles, namely involvement in primary and basal specialized metabolisms for class I and inducible specialized metabolism for class II. By studying the role of CPRs in the biosynthesis of monoterpene indole alkaloids, we provide compelling evidence of an operational specialization of CPR isoforms in Catharanthus roseus (Madagascar periwinkle). Global analyses of gene expression correlation combined with transcript localization in specific leaf tissues and gene-silencing experiments of both classes of CPR all point to the strict requirement of class II CPRs for monoterpene indole alkaloid biosynthesis with a minimal or null role of class I. Direct assays of interaction and reduction of P450s in vitro, however, showed that both classes of CPR performed equally well. Such high specialization of class II CPRs in planta highlights the evolutionary strategy that ensures an efficient reduction of P450s in specialized metabolism. PMID- 27688621 TI - Phosphorylation of GENOMES UNCOUPLED 4 Alters Stimulation of Mg Chelatase Activity in Angiosperms. AB - GENOMES UNCOUPLED 4 (GUN4) is a positive regulator of light-dependent chlorophyll biosynthesis. GUN4 activates Mg chelatase (MgCh) that catalyzes the insertion of an Mg2+ ion into protoporphyrin IX. We show that Arabidopsis (Arabidopsis thaliana) GUN4 is phosphorylated at Ser 264 (S264), the penultimate amino acid residue at the C terminus. While GUN4 is preferentially phosphorylated in darkness, phosphorylation is reduced upon accumulation of Mg porphyrins. Expression of a phosphomimicking GUN4(S264D) results in an incomplete complementation of the white gun4-2 null mutant and a chlorotic phenotype comparable to gun4 knockdown mutants. Phosphorylated GUN4 has a reduced stimulatory effect on MgCh in vitro and in vivo but retains its protein stability and tetrapyrrole binding capacity. Analysis of GUN4 found in oxygenic photosynthetic organisms reveals the evolution of a C-terminal extension, which harbors the phosphorylation site of GUN4 expressed in angiosperms. Homologs of GUN4 from Synechocystis and Chlamydomonas lack the conserved phosphorylation site found in a C-terminal extension of angiosperm GUN4. Biochemical studies proved the importance of the C-terminal extension for MgCh stimulation and inactivation of GUN4 by phosphorylation in angiosperms. An additional mechanism regulating MgCh activity is proposed. In conjunction with the dark repression of 5 aminolevulinic acid synthesis, GUN4 phosphorylation minimizes the flow of intermediates into the Mg branch of the tetrapyrrole metabolic pathway for chlorophyll biosynthesis.

PMID- 27688624 TI - Comparison of low- and high-dose recombinant activated factor VII for postcardiac surgical bleeding. AB - AIM OF THE STUDY: A retrospective observational study to compare safety and efficacy of high and low doses of recombinant activated factor VIIa (rFVIIa) in severe postcardiac surgical bleeding. PATIENTS AND METHODS: From 2004 to 2014, all patients who received rFVIIa for bleeding after cardiac surgery were included and arranged in two groups; Group 1: Low dose (40-50 mcg/kg) (n = 98) and Group 2: High dose (90-120 mcg/kg) (n = 156). RESULTS: There was no significant difference in demographic and surgical characteristics of both groups on admission to Cardiac Surgical Intensive Care Unit (CSICU). There was no significant difference between the two groups regarding the reduction in chest tube bleeding in the first 6 h or the transfusion requirement in the 24 h after admission to CSICU. A total of 15 patients (5.9%) had thromboembolic adverse events. (Seven (7.1%) patients in Group 1 compared to 8 (5.1%) patients in Group 2, P = 0.58). There were no significant differences in all-cause mortality at 30 days (2% in Group 1 vs. 3.2% in Group 2, P = 0.6) and at hospital discharge between the two study groups (6.1% in Group 1 vs. 8.3% in Group 2, P = 0.5), respectively. There was no significant difference between the two groups regarding the need for re-exploration, days on mechanical ventilation, CSICU, or hospital stay. CONCLUSION: In this report, Low-dose rFVIIa showed equivalent efficacy and safety to high-dose rFVIIa. Further prospective randomized studies are needed to confirm these findings. PMID- 27688625 TI - Rhabdomyolysis and acute kidney injury in patients with traumatic spinal cord injury. AB - BACKGROUND: Patients with acute traumatic spinal cord injuries (SCIs) exhibit factors that, in other populations, have been associated with rhabdomyolysis. PURPOSE: The aim of the study is to determine the incidence of rhabdomyolysis in patients with acute traumatic SCI admitted to the Intensive Care Unit (ICU), as well as the development of secondary acute kidney injury and associated factors. STUDY DESIGN AND SETTING: This was an observational, retrospective study. PATIENT SAMPLE: All adult patients admitted to the ICU with acute traumatic SCI who presented rhabdomyolysis, diagnosed through creatine phosphokinase (CPK) levels >500 IU/L. OUTCOME MEASURES: Incidence of rhabdomyolysis and subsequent renal dysfunction was calculated. MATERIALS AND METHODS: Data about demographic variables, comorbidity, rhabdomyolysis risk factors, and variables involving SCI, severity scores, and laboratory parameters were obtained from clinical records. Multivariate logistic regression was used to identify renal injury risk factors. RESULTS: In 2006-2014, 200 patients with acute SCI were admitted to ICU. Of these, 103 had rhabdomyolysis (incidence = 51.5%; 95% confidence interval [CI]: 44.3%-58.7%). The most typical American Spinal Injury Association classification was A (70.3%). The injury severity score was 30.3 +/- 12.1 and sequential organ failure assessment (SOFA) score was 5.6 +/- 3.3 points. During their stay, 57 patients (55.3%; 95% CI: 45.2%-65.4%) presented renal dysfunction (creatinine >=1.2 mg/dL). In the multivariate analysis, variables associated with renal dysfunction were creatinine at admission (odds ratio [OR] = 9.20; P = 0.006) and hemodynamic SOFA score the day following admission (OR = 1.33; P = 0.024). Creatinine was a better predictor of renal dysfunction than the peak CPK value during the rhabdomyolysis (area under the receiver operating characteristic curve: 0.91 vs. 0.63, respectively). CONCLUSIONS: Rhabdomyolysis is a frequent condition in patients with acute traumatic SCI admitted to the ICU, and renal dysfunction occurs in half of the cases. Creatinine values should be requested starting at the admission while neither the peak CPK values nor the hemodynamic SOFA scores could be used to properly discriminate between patients with and without renal dysfunction. PMID- 27688623 TI - The Nonspecific Lipid Transfer Protein AtLtpI-4 Is Involved in Suberin Formation of Arabidopsis thaliana Crown Galls. AB - Nonspecific lipid transfer proteins reversibly bind different types of lipid molecules in a hydrophobic cavity. They facilitate phospholipid transfer between membranes in vitro, play a role in cuticle and possibly in suberin formation, and might be involved in plant pathogen defense signaling. This study focuses on the role of the lipid transfer protein AtLTPI-4 in crown gall development. Arabidopsis (Arabidopsis thaliana) crown gall tumors, which develop upon infection with the virulent Agrobacterium tumefaciens strain C58, highly expressed AtLTPI-4 Crown galls of the atltpI-4 loss-of-function mutant were much smaller compared with those of wild-type plants. The gene expression pattern and localization of the protein to the plasma membrane pointed to a function of AtLTPI-4 in cell wall suberization. Since Arabidopsis crown galls are covered by a suberin-containing periderm instead of a cuticle, we analyzed the suberin composition of crown galls and found a reduction in the amounts of long-chain fatty acids (C18:0) in the atltpI-4 mutant. To demonstrate the impact of AtLtpI-4 on extracellular lipid composition, we expressed the protein in Arabidopsis epidermis cells. This led to a significant increase in the very-long-chain fatty acids C24 and C26 in the cuticular wax fraction. Homology modeling and lipid protein-overlay assays showed that AtLtpI-4 protein can bind these very-long chain fatty acids. Thus, AtLtpI-4 protein may facilitate the transfer of long chain as well as very-long-chain fatty acids into the apoplast, depending on the cell type in which it is expressed. In crown galls, which endogenously express AtLtpI-4, it is involved in suberin formation. PMID- 27688626 TI - Bronchoalveolar lavage fluid cytokine bead array profile for prognostication of ventilated trauma patients. AB - AIM OF STUDY: Ventilator-associated pneumonia (VAP) is a common cause of mortality in trauma patients admitted to Intensive Care Units. The outcome of such patients may be dependent on local host immune response, which may be best reflected in studies using bronchoalveolar lavage (BAL) fluid. The present study was conducted to ascertain the cytokine profile of BAL using the cytometric bead array (CBA) in a flow cytometer and to correlate the levels of Th-1/Th-2 cytokines in BAL with the clinical outcome of ventilated trauma patients. PATIENTS AND METHODS: BAL was collected from the patients with suspected VAP. CBA was performed to assess the levels of interleukin-4 (IL-4), IL-6, IL-8, IL-1 beta, interferon gamma (IFN-gamma), and tumor necrosis factor-alpha in the BAL samples. After acquiring the BAL samples on the flow cytometer, the results were generated using FCAP ArrayTM software. The cytokine profile was correlated to clinical outcomes. RESULTS: A total of forty patients were enrolled during the study period. Of these, 12 patients (30%) had confirmed VAP and 8 (20%) patients had a fatal outcome. The levels of IL-8 and IFN-gamma correlated significantly with the development of VAP and elevated IL-6 in BAL was associated with a poor outcome. CONCLUSION: A proinflammatory response in the form of elevated IL-6 and IL-8 correlated poorly with the clinical outcome. Th-1 response was significantly reduced in patients with VAP. A proinflammatory response in the form of elevated IL-6 and IL-8 correlated poorly with the clinical outcome. PMID- 27688627 TI - Association of serum interleukin-6, interleukin-8, and Acute Physiology and Chronic Health Evaluation II score with clinical outcome in patients with acute respiratory distress syndrome. AB - BACKGROUND AND AIM: Studies on potential biomarkers in experimental models of acute lung injury (ALI) and clinical samples from patients with ALI have provided evidence to the pathophysiology of the mechanisms of lung injury and predictor of clinical outcome. Because of the high mortality and substantial variability in outcomes in patients with acute respiratory distress syndrome (ARDS), identification of biomarkers such as cytokines is important to determine prognosis and guide clinical decision-making. MATERIALS AND METHODS: In this study, we have included thirty patients admitted to Intensive Care Unit diagnosed with ARDS, and serum samples were collected on day 1 and 7 and were analyzed for serum interleukin-6 (IL-6) and IL-8 by ELISA method, and Acute Physiology and Chronic Health Evaluation II (APACHE II) scoring was done on day 1. RESULTS: The mortality in the patients observed with ARDS was 34%. APACHE II score was significantly higher in nonsurvivors as compared to survivors. There were no significant differences in gender and biochemical and hematological parameters among the survivors and nonsurvivors. Serum IL-6 and IL-8 levels on day 1 were significantly higher in all the ARDS patients as compared to healthy controls and these levels were returned to near-normal basal levels on day 7. The serum IL-6 and IL-8 levels measured on day 7 were of survivors. As compared to survivors, the IL-6 and IL-8 levels were significantly higher in nonsurvivors measured on day 1. Spearman's rank correlation analysis indicated a significant positive correlation of APACHE II with IL-8. By using APACHE II score, IL-6, and IL-8, the receiver operating characteristic curve was plotted and the provided predictable accuracy of mortality (outcome) was 94%. CONCLUSION: The present study highlighted the importance of measuring the cytokines such as IL-6 and IL-8 in patients with ARDS in predicting the clinical outcome. PMID- 27688628 TI - Acute kidney injury in Pediatric Intensive Care Unit: Incidence, risk factors, and outcome. AB - OBJECTIVE: To determine incidence, risk factors, and outcome of acute kidney injury (AKI) in Pediatric Intensive Care Unit (PICU). MATERIALS AND METHODS: This is a prospective, observational study conducted in PICU of Department of Paediatrics, S.P. Medical College, Bikaner, from October 2013 to May 2014. In this study, 536 patients of aged 29 days to 16 years were screened for AKI according to the Pediatric Risk, Injury, Failure, Loss, End-stage Renal Disease (pRIFLE) criteria. Their clinical and biochemical data were recorded and followed up to their discharge/death. RESULTS: During the study period, 230 (42.9%) out of 536 patients developed AKI. Younger age (<5 years) and females (P <= 0.013) were more prone to develop AKI. Most common etiologies were septicemia, multiple organ dysfunction syndrome (MODS), gastroenteritis, and severe malaria (P <= 0.05). The maximal stage of AKI was stage "R" (49.1%), followed by "I" (29.5%) and "F" (21.3%). Major PICU-related risk factors were use of vasoactive drug (VD) and nephrotoxic drug (ND) and need of mechanical ventilation (MV) (P <= 0.05). Length of stay was significantly longer than non-AKI patients (P <= 0.05). Mortality in AKI (47.5%) was higher (P <= 0.05%) in comparison to non-AKI (25.56%). CONCLUSION: AKI is common in critically sick children, especially in younger age and in females with septicemia and MODS. Use of VD and ND and need of MV are common risk factors. AKI is associated with longer hospital stay and higher mortality. pRIFLE is better diagnostic criteria in early detection of AKI and reduction of their morbidity and mortality. PMID- 27688629 TI - Comparative evaluation of the role of single and multiple blood specimens in the outcome of blood cultures using BacT/ALERT 3D (automated) blood culture system in a tertiary care hospital. AB - INTRODUCTION: Bloodstream infection (BSI) is a leading cause of mortality in critically ill patients. The mortality directly attributable to BSI has been estimated to be around 16% and 40% in general hospital population and Intensive Care Unit (ICU) population, respectively. The detection rate of these infections increases with the number of blood samples obtained for culture. The newer continuous monitoring automated blood culture systems with enhanced culture media show increased yield and sensitivity. Hence, we aimed at studying the role of single and multiple blood specimens from different sites at the same time in the outcome of automated blood culture system. MATERIALS AND METHODS AND RESULTS: A total of 1054 blood culture sets were analyzed over 1 year, the sensitivity of one, two, and three samples in a set was found to be 85.67%, 96.59%, and 100%, respectively, which showed a statistically significant difference (P < 0.0001). Similar findings were seen in few more studies, however, among individual organisms in contrast to other studies, the isolation rates of Gram-positive bacteria were less than that of Gram-negative Bacilli with one (or first) sample in a blood culture set. In our study, despite using BacT/ALERT three-dimensional continuous culture monitoring system with FAN plus culture bottles, 15% of positive cultures would have been missed if only a single sample was collected in a blood culture set. CONCLUSION: The variables like the volume of blood and number of samples collected from different sites still play a major role in the outcome of these automated blood culture systems.

We present a rapidly fatal case of obstructive shock where a vigilant intensivist could diagnose left atrial mass obstructing the mitral inflow as the etiology of shock. PMID- 27688630 TI - Systematic review of statins in sepsis: There is no evidence of dose response. AB - OBJECTIVES: Sepsis is a common cause of morbidity and mortality and is associated with significant costs to the healthcare organizations. We performed a systematic review and meta-analysis to assess whether high or low-dose statin therapy improved mortality in patients with sepsis. METHODS: The trials analyzed in this study were multicenter or single center randomized control studies using statins for sepsis in a hospital setting. The patients included were adults with suspected or confirmed infection. INTERVENTIONS: This study found eight randomized controlled trials where participants were given either a statin or placebo daily for 14-28 days, the duration of their illness, or until their death or discharge, which ever occurred first. PRIMARY AND SECONDARY OUTCOMES MEASURED: This meta-analysis measured the effect of statin therapy on in hospital and 28 days mortality. RESULTS: In unselected patients, there was no demonstrable difference in the 28 days mortality (relative risk [RR] 0.88 95% confidence interval [CI], 0.70-1.12 and P = 0.16). There was also no significant difference between statin versus placebo for in-hospital mortality (RR 0.98 95% CI, 0.85 1.14 P = 0.36). When the studies where divided into low-dose and high-dose groups, there were no statistically significant differences for in-hospital mortality between low-dose statin versus placebo for (RR 0.81 CI 0.44-1.49 P = 0.27) or high-dose statin versus placebo (RR 0.99 95% CI 0.85-1.16, P = 0.28). There was no significant difference in adverse effects between the high- and low dose groups. CONCLUSIONS: In this meta-analysis, we found that the use of statins did not significantly improve either in-hospital mortality or 28-day mortality in patients with sepsis. In the low-dose group, there were fewer quality multicenter studies; hence, conclusions based on the results of this subgroup are limited. PMID- 27688632 TI - Point-of-care ultrasonography of the orbit for detection of retinal detachment in a patient with hemolysis, elevated liver enzymes, and low platelet count syndrome. AB - Retinal detachment is a rare, but well-known cause of visual impairment in patients with hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. With supportive care, patients usually improve, with complete recovery of vision. Bedside ultrasonography of the orbit can be helpful for early detection of retinal detachment in these patients. Here, we present a case of HELLP syndrome presenting with severe visual symptoms. Retinal detachment was detected with point-of-care ocular sonography, which was confirmed with ophthalmoscopic examination. The patient was reassured of the favorable prognosis. Early initiation of aggressive supportive care was followed by progressive improvement of vision, which correlated with sonographic evidence of resolution of detachment. Her vision recovered completely in 2 weeks. PMID- 27688633 TI - Lance-Adams syndrome: A special case of a mother. AB - Predicting the neurological outcome in survivors of cardiorespiratory arrest is difficult. A distinction has been made between acute and chronic posthypoxic myoclonus, called myoclonic status epilepticus and Lance-Adams syndrome (LAS), respectively, with the acute condition carrying a bad prognosis. Here, we report a case of a 37-year-old female who developed seizures after a successful cardiopulmonary resuscitation. The available literature on such cases is very rare and has generally mentioned a poor outcome. However, our patient was successfully managed and showed clinical features of LAS. Thus, making an early diagnosis and proper management of hypoxic brain insults is positively related to improving the patient's functional outcome. PMID- 27688634 TI - Hantavirus pulmonary syndrome in a postpartum woman. AB - Hantavirus infection, a rare disease diagnosed in India and carries a very high mortality. There are no reports of this infection in association with pregnancy or postpartum period in our country. We present a case of a 30-year-old female diagnosed to have hantavirus pulmonary syndrome in the postpartum period. We intend to create awareness about this infection and consider it in the differential diagnosis of patients presenting with acute respiratory distress syndrome and multiorgan dysfunction in association with pregnancy and postpartum period.

PMID- 27688638 TI - E-learning in orthopedic surgery training: A systematic review. AB - E-learning is the use of internet-based resources in education. In the field of surgical education, this definition includes the use of virtual patient cases, digital modeling, online tutorials, as well as video recordings of surgical procedures and lectures. In recent years, e-learning has increasingly been considered a viable alternative to traditional teaching within a number of surgical fields. Here we present (1) a systematic review of literature assessing the efficacy of e-learning modules for orthopedic education and (2) a discussion of their relevance. A systematic search of PubMed, Embase, Web of Science, and the Cochrane Library was conducted according to the guidelines defined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA). The search yielded a total of 255 non-duplicate citations that were screened using predetermined inclusion/exclusion criteria. A total of 9 full text articles met inclusion criteria, which included the use of an objective outcome measure to evaluate an orthopedic e-learning module. Six studies assessed knowledge using a multiple-choice test and 4 assessed skills using a clinical exam. All studies showed positive score improvement pre- to post-intervention, and a majority showed greater score improvement than standard teaching methods in both knowledge (4/6 studies) and clinical skills (3/4 studies). E-learning represents an effective supplement or even alternative to standard teaching techniques within orthopedic education for both medical students and residents. Future work should focus on validating specific e-learning programs using standardized outcome measures and assessing long-term knowledge retention using e learning platforms.

PMID- 27688640 TI - Effect of group cognitive-behavioral therapy on the quality of life and social functioning of patients with mild depression. AB - BACKGROUND: Several studies of moderate-to-severe depression have shown that combined treatment with individual cognitive behavioral therapy (CBT) and antidepressant medication is better than either CBT or antidepressants alone. Less research has focused on the outcomes of group-CBT and antidepressants in persons with mild depression. AIM: Evaluate the effects of group-CBT in combination with antidepressants on the quality of life and social functioning of outpatients with mild depression. METHODS: We randomized 62 outpatients with mild depression into a control group (n=30) that received antidepressant medication for 12 weeks and an intervention group (n=32) that received antidepressants and group-CBT for 12 weeks; both groups were then continued on antidepressants alone for one year. Blinded evaluators used Chinese versions of the Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Social Disability Screening Schedule, Life Satisfaction Rating, Multidimensional Scale of Perceived Social Support, and Short Form Health Survey to assess participants after 12 weeks of treatment and at the end of one year of follow-up. RESULTS: Repeated measures analysis of variance showed that the depressive and anxiety symptoms of both groups improved significantly during treatment and that the improvement was greater in the CBT+antidepressant experimental group. Almost all of the social functioning, social support, and quality of life measures also showed significantly greater improvement in the CBT+antidepressant group than in the antidepressant-only group. Moreover, even after adjusting for differences in baseline demographic and clinical characteristics and for changes in the severity of depression and anxiety over time using an analysis of covariance, the greater improvement in the CBT+antidepressant group remained statistically significant both after the 12 weeks of group-CBT treatment and one year after the group CBT had ended. CONCLUSION: Antidepressants alone or combined treatment with antidepressants and group-CBT can effectively improve the social function, quality of life, and healthy functioning of individuals with mild depression. However, combined treatment with both antidepressants and group CBT is better than treatment with antidepressants alone, and these benefits persist for up to one year after the CBT sessions have ended. PMID- 27688641 TI - Comparison of cognitive flexibility and planning ability in patients with obsessive compulsive disorder, patients with obsessive compulsive personality disorder, and healthy controls. AB - BACKGROUND: Cognitive functioning in individuals with Obsessive Compulsive Disorder (OCD) and with Obsessive Compulsive Personality Disorder (OCPD) has not been adequately studied. AIM: Examine the cognitive flexibility and planning ability of individuals with OCD and OCPD. METHODS: Twenty patients with OCD and 25 patients with OCPD who had not taken medication in the previous two weeks were identified in an outpatient psychology clinic in Tehran, and 25 healthy control subjects were identified from the university staff and local community residents. All participants were administered the 28-item version of the General Health Questionnaire (GHQ-28), the Wisconsin Card Sorting Test (WCST), and the Tower of London (TOL) test. Two measures of the WCTS (number of perseverative errors and number of categories completed) were used to assess cognitive flexibility and three measures of the TOL (total number of moves in 12 trials, total response time, and planning time) were used to assess planning ability. RESULTS: The level of current psychological distress in the two patient groups was significantly greater than that in the control group. After adjusting for demographic variables and the level of psychological distress, both OCD patients and OCPD patients made more perseverative errors on the WCST than control subjects, and the OCD patients (but not the OCPD patients) completed significantly fewer categories than the control subjects. Both the OCD patients and OCPD patients required significantly more moves than control subjects to complete the 12 TOL tasks and OCD patients took significantly longer than both OCPD patients and control subjects to complete the tasks. CONCLUSIONS: Individuals with OCD and OCPD have impaired cognitive flexibility and planning ability compared to healthy controls, and there are some differences in these measures of cognitive functioning between OCD and OCPD. Long term follow-up studies of OCD and OCPD that assess changes in cognitive measures as the severity of obsessive compulsive symptoms wax and wane will be needed to determine whether or not such cognitive measures have diagnostic or clinical relevance for obsessive compulsive disorders. PMID- 27688642 TI - Cross-sectional study of the severity of self-reported depressive symptoms in heroin users who participate in a methadone maintenance treatment program. AB - BACKGROUND: Methadone maintenance treatment (MMT) is widely recognized as an effective method of combatting narcotic addiction. MMT reduces heroin withdrawal symptoms and, thus, makes it possible to provide the psychological and social support that is essential to the rehabilitation of drug users. AIM: Compare the severity of depressive symptoms in heroin users who are currently receiving MMT to that of heroin users who are not receiving MMT. METHODS: We administered the 13-item version of the Beck Depression Inventory (BDI-13) and a demographic history form to 929 heroin users who had been receiving MMT at nine methadone treatment clinics in three Chinese cities for an average of 9 months and to 238 heroin users who had enrolled in a MMT program at the centers but had not yet begun MMT. RESULTS: Seventy-nine percent (188/238) of the untreated individuals reported depressive symptoms compared to 68% (628/929) of the individuals receiving MMT (chi (2)=11.69, p<0.001). The median (interquartile range) BDI score in the untreated group was 10.4 (7.9-11.4) compared to 8.0 (5.7-11.6) in the MMT group (Z=2.75, p=0.006). In the MMT group, there was a negative correlation between the severity of reported depressive symptoms and the duration of participation in the MMT program (rs =-0.24, Z=2.88, p=0.004). Multivariate linear regression analysis showed that after adjusting for all demographic variables the treated group still had less severe depressive symptoms than the untreated group. After adjusting for the effect of MMT treatment, depressive symptoms were more severe in heroin users who self-reported poor family relationships (standardized regression coefficient beta=0.118, t=6.56, p<0.001) and in those who were divorced (beta=0.120, t=3.73, p<0.001). CONCLUSIONS: Moderate to severe depressive symptoms are common in heroin users. MMT is associated with lower levels of depressive symptoms in heroin users, but prospective randomized controlled trials are needed to determine whether or not MMT actually improves depressive symptoms in heroin users. Poor relationships with family members are also associated with depressive symptoms in heroin users; this suggests that treatment of heroin addiction needs to incorporate methods for helping heroin users repair the severed social relationships that their addiction has caused. PMID- 27688643 TI - Genetic findings are challenging the symptom-based diagnostic classification system of mental disorders. AB - The present diagnostic classification of mental illnesses is primarily based on symptomatology. A recent cross-disorder genome-wide association study revealed that there were genetic similarities between multiple clinically defined diagnoses (including schizophrenia, bipolar disorder, depression, attention deficit hyperactivity disorder, and autism spectrum disorder) on regions of chromosomes 3p21 and 10q24 and single-nucleotide polymorphisms (SNPs) within two L-type voltage-gated calcium channel subunits of CACNA1C and CACNB2. These findings suggest that the pathogenesis of these five independent disorders are related. Such cross-disorder genetic studies challenge the current symptom-based diagnostic classification of mental disorders. Researchers need to identify creative ways to bridge the gap between these two approaches to understanding and labelling mental disorders. PMID- 27688644 TI - Influence of cross-disorder analyses on the diagnostic criteria of mental illnesses. AB - Cross-disorder studies are identifying shared genetic variations among common mental illnesses - including schizophrenia, bipolar disorder, and major depression - which are classified as independent disorders in the current diagnostic system. These cross-disorder studies are challenging the traditional system of diagnosing mental disorders based on clinical symptoms, but it remains to be seen whether or not they will lead to an improved method of classifying psychiatric disorders that can, in turn, lead to better outcomes for individuals suffering from these conditions. PMID- 27688645 TI - Case report of body dysmorphic disorder in a suicidal patient. AB - Few reports exist about the treatment of body dysmorphic disorder (BDD) in patients who are suicidal. This case report describes a 19-year-old male with BDD who had delusional-intensity beliefs about facial disfigurement that had gradually intensified over a 2-year period. However, he was initially misdiagnosed with depression partly because he was admitted immediately after a suicide attempt that was associated with depressive symptoms and social withdrawal, symptoms that subsequently proved to be secondary to his BDD. The symptoms resolved completely and his social functioning returned to normal after 8 weeks of inpatient treatment with fluoxetine and cognitive behavioral therapy. This report is a reminder that suicidal behavior and ideation can have many causes; to avoid misdiagnosis and inappropriate treatment, clinicians should consider other possibilities before assuming that suicidal behavior or ideation is the direct result of depression. We discuss the many changes in the understanding and diagnostic classification of BDD since it was first reported by Enrico Morselli in 1886. PMID- 27688646 TI - Case report of a child's anxiety disorder precipitated by tremors from a distant earthquake that was extensively covered in local news stories. AB - Earthquakes are relatively common natural disasters in many parts of the world, but research about the mental health effects of earthquakes remains limited. Individuals experiencing an earthquake often suffer significant loss and are at increased risk for developing mental disorders. However, the prevalence of mental disorders following less dramatic or non-destructive earthquake phenomena is unknown. We report the case of a 10-year-old girl who came to a psychiatric outpatient department with a 2-week history of severe, disabling anxiety symptoms precipitated by non-destructive tremors from a distant earthquake that received extensive coverage in the local press. Her condition did not meet criteria for any of the specific anxiety-related disorders, so the non-specific DSM-5 category 'Other Specified Anxiety Disorder' was considered most appropriate. Her symptoms resolved over 4 weeks when treated with both a benzodiazepine and a selective serotonin reuptake inhibitor. PMID- 27688647 TI - Relationships among three popular measures of differential risks: relative risk, risk difference, and odds ratio. AB - The relative risk, risk difference, and odds ratio are the three most commonly used measures for comparing the risk of disease between different groups. Although widely popular in biomedical and psychosocial research, the relationship among the three measures has not been clarified in the literature. Many researchers incorrectly assume a monotonic relationship, such that higher (or lower) values in one measure are associated with higher (or lower) values in the other measures. In this paper we discuss three theorems and provide examples demonstrating that this is not the case; there is no logical relationship between any of these measures. Researchers must be very cautious when implying a relationship between the different measures or when combining results of studies that use different measures of risk. PMID- 27688648 TI - Segmental colitis associated diverticulosis syndrome. AB - Segmental colitis associated diverticulosis (SCAD) has become increasingly appreciated as a form of inflammatory disease of the colon. Several features suggest that SCAD is a distinct disorder. SCAD tends to develop almost exclusively in older adults, predominately, but not exclusively, males. The inflammatory process occurs mainly in the sigmoid colon, and usually remains localized to this region of the colon alone. SCAD most often presents with rectal bleeding and subsequent endoscopic visualization reveals a well localized process with non-specific histopathologic inflammatory changes. Granulomas are not seen, and if present, may be helpful in definition of other disorders such as Crohn's disease of the colon, an entity often confused with SCAD. Bacteriologic and parasitic studies for an infectious agent are negative. Normal rectal mucosa (i.e., "rectal sparing") is present and can be confirmed with normal rectal biopsies. SCAD often resolves spontaneously without treatment, or completely after a limited course of therapy with only a 5-aminosalicylate. Recurrent episodes may occur, but most often, patients with this disorder have an entirely self-limited clinical course. Occasionally, treatment with other agents, including corticosteroids, or surgical resection has been required. PMID- 27688649 TI - Guanylyl cyclase C signaling axis and colon cancer prevention. AB - Colorectal cancer (CRC) is a major cause of cancer-related mortality and morbidity worldwide. While improved treatments have enhanced overall patient outcome, disease burden encompassing quality of life, cost of care, and patient survival has seen little benefit. Consequently, additional advances in CRC treatments remain important, with an emphasis on preventative measures. Guanylyl cyclase C (GUCY2C), a transmembrane receptor expressed on intestinal epithelial cells, plays an important role in orchestrating intestinal homeostatic mechanisms. These effects are mediated by the endogenous hormones guanylin (GUCA2A) and uroguanylin (GUCA2B), which bind and activate GUCY2C to regulate proliferation, metabolism and barrier function in intestine. Recent studies have demonstrated a link between GUCY2C silencing and intestinal dysfunction, including tumorigenesis. Indeed, GUCY2C silencing by the near universal loss of its paracrine hormone ligands increases colon cancer susceptibility in animals and humans. GUCY2C's role as a tumor suppressor has opened the door to a new paradigm for CRC prevention by hormone replacement therapy using synthetic hormone analogs, such as the FDA-approved oral GUCY2C ligand linaclotide (LinzessTM). Here we review the known contributions of the GUCY2C signaling axis to CRC, and relate them to a novel clinical strategy targeting tumor chemoprevention. PMID- 27688651 TI - Epidemiology of hepatitis C in Greece. AB - Hepatitis C is a global health issue and constitutes a major cause of chronic liver disease worldwide. In this article, a comprehensive literature search was conducted for the prevalence of hepatitis C virus (HCV) infection in Greece, since data on the HCV prevalence, viremia and genotypes are important for developing strategies to manage or eliminate HCV infection. In addition, the pattern of HCV infection was analyzed according to the geographic region and the risk factors. These differences reflect not only distinct epidemiological characteristics among populations, but also differences on the strategy of data acquisition and quantification. Although there are not enough data, the estimation of the current prevalence of Hepatitis C in Greece ranges from 0.5% to 2%. The most important risk factors for HCV infection include blood product transfusion, intravenous drug use, chronic hemodialysis, organ transplantation, occupational exposure, sexual transmission, and vertical transmission. Because of lack of vaccine or effective post-exposure prophylaxis for HCV, the main focus of prevention is to recognize and control these risk factors. HCV infection in Greece is closely associated with the development of chronic liver disease, cirrhosis, and primary hepatocellular carcinoma. As far as the genotype distribution is concerned genotype 1 estimated to be 45%-47% and it constitutes the prevalent genotype in Greece, followed by genotype 3. PMID- 27688650 TI - Pediatric non-alcoholic fatty liver disease: Recent solutions, unresolved issues, and future research directions. AB - Non-alcoholic fatty liver disease (NAFLD) in children is becoming a major health concern. A "multiple-hit" pathogenetic model has been suggested to explain the progressive liver damage that occurs among children with NAFLD. In addition to the accumulation of fat in the liver, insulin resistance (IR) and oxidative stress due to genetic/epigenetic background, unfavorable lifestyles, gut microbiota and gut-liver axis dysfunction, and perturbations of trace element homeostasis have been shown to be critical for disease progression and the development of more severe inflammatory and fibrotic stages [non-alcoholic steatohepatitis (NASH)]. Simple clinical and laboratory parameters, such as age, history, anthropometrical data (BMI and waist circumference percentiles), blood pressure, surrogate clinical markers of IR (acanthosis nigricans), abdominal ultrasounds, and serum transaminases, lipids and glucose/insulin profiles, allow a clinician to identify children with obesity and obesity-related conditions, including NAFLD and cardiovascular and metabolic risks. A liver biopsy (the "imperfect" gold standard) is required for a definitive NAFLD/NASH diagnosis, particularly to exclude other treatable conditions or when advanced liver disease is expected on clinical and laboratory grounds and preferably prior to any controlled trial of pharmacological/surgical treatments. However, a biopsy clearly cannot represent a screening procedure. Advancements in diagnostic serum and imaging tools, especially for the non-invasive differentiation between NAFLD and NASH, have shown promising results, e.g., magnetic resonance elastography. Weight loss and physical activity should be the first option of intervention. Effective pharmacological treatments are still under development; however, drugs targeting IR, oxidative stress, proinflammatory pathways, dyslipidemia, gut microbiota and gut liver axis dysfunction are an option for patients who are unable to comply with the recommended lifestyle changes. When morbid obesity prevails, bariatric surgery should be considered. PMID- 27688652 TI - How significant is the association between metabolic syndrome and prevalence of colorectal neoplasia? AB - The incidence and prevalence of metabolic syndrome (MS) and colorectal cancer (CRC) has been rising in developed countries. The association between these two diseases has been widely studied and reported. Less evidence is available about the relationship between MS and CRC precancerous lesions (adenomatous polyps, adenomas). The aim of this paper is to present an overview of our scientific understanding of that topic and its implication in clinical practice. One of the principal goals of current CRC secondary prevention efforts is to detect and remove the precancerous lesions in individuals with an average CRC risk to prevent the development of invasive cancer. MS is not currently considered a high risk CRC factor and is therefore not included in the guidelines of organized screening programs. However, in light of growing scientific evidence, the approach to patients with MS should be changed. Metabolic risk factors for the development of adenomas and cancers are the same - obesity, impaired glucose tolerance, dyslipidemia, hypertension, cardiovascular diseases and diabetes mellitus type 2. Therefore, the key issue in the near future is the development of a simple scoring system, easy to use in clinical practice, which would identify individuals with high metabolic risk of colorectal neoplasia and would be used for individual CRC secondary prevention strategies. Currently, such scoring systems have been published based on Asian (Asia-Pacific Colorectal Screening Score; APCS) and Polish populations. PMID- 27688653 TI - Iron and non-alcoholic fatty liver disease. AB - The mechanisms that promote liver injury in non-alcoholic fatty liver disease (NAFLD) are yet to be thoroughly elucidated. As such, effective treatment strategies are lacking and novel therapeutic targets are required. Iron has been widely implicated in the pathogenesis of NAFLD and represents a potential target for treatment. Relationships between serum ferritin concentration and NAFLD are noted in a majority of studies, although serum ferritin is an imprecise measure of iron loading. Numerous mechanisms for a pathogenic role of hepatic iron in NAFLD have been demonstrated in animal and cell culture models. However, the human data linking hepatic iron to liver injury in NAFLD is less clear, with seemingly conflicting evidence, supporting either an effect of iron in hepatocytes or within reticulo-endothelial cells. Adipose tissue has emerged as a key site at which iron may have a pathogenic role in NAFLD. Evidence for this comes indirectly from studies that have evaluated the role of adipose tissue iron with respect to insulin resistance. Adding further complexity, multiple strands of evidence support an effect of NAFLD itself on iron metabolism. In this review, we summarise the human and basic science data that has evaluated the role of iron in NAFLD pathogenesis. PMID- 27688654 TI - Inflammatory bowel disease in India - Past, present and future. AB - There is rising incidence and prevalence of inflammatory bowel disease (IBD) in India topping the Southeast Asian (SEA) countries. The common genes implicated in disease pathogenesis in the West are not causal in Indian patients and the role of "hygiene hypothesis" is unclear. There appears to be a North-South divide with more ulcerative colitis (UC) in north and Crohn's disease (CD) in south India. IBD in second generation Indian migrants to the West takes the early onset and more severe form of the West whereas it retains the nature of its country of origin in migrants to SEA countries. The clinical presentation is much like other SEA countries (similar age and sex profile, low positive family history and effect of smoking, roughly similar disease location, use of aminosalicylates for CD, low use of biologics and similar surgical rates) with some differences (higher incidence of inflammatory CD, lower perianal disease, higher use of aminosalicylates and azathioprine and lower current use of corticosteroids). UC presents more with extensive disease not paralleled in severity clinically or histologically, follows benign course with easy medical control and low incidence of fulminant disease, cancer, complications, and surgery. UC related colorectal cancer develop in an unpredictable manner with respect to disease duration and site questioning the validity of strict screening protocol. About a third of CD patients get antituberculosis drugs and a significant number presents with small intestinal bleed which is predominantly afflicted by aggressive inflammation. Biomarkers have inadequate diagnostic sensitivity and specificity for both. Pediatric IBD tends to be more severe than adult. Population based studies are needed to address the lacunae in epidemiology and definition of etiological factors. Newer biomarkers and advanced diagnostic techniques (in the field of gastrointestinal endoscopy, molecular pathology and genetics) needs to be developed for proper disease definition and treatment. PMID- 27688657 TI - Impact of hepatitis B virus infection on hepatic metabolic signaling pathway. AB - A growing body of epidemiologic research has demonstrated that metabolic derangement exists in patients with hepatitis B virus (HBV) infection, indicating that there are clinical associations between HBV infection and host metabolism. In order to understand the complex interplay between HBV and hepatic metabolism in greater depth, we systematically reviewed these alterations in different metabolic signaling pathways due to HBV infection. HBV infection interfered with most aspects of hepatic metabolic responses, including glucose, lipid, nucleic acid, bile acid and vitamin metabolism. Glucose and lipid metabolism is a particular focus due to the significant promotion of gluconeogenesis, glucose aerobic oxidation, the pentose phosphate pathway, fatty acid synthesis or oxidation, phospholipid and cholesterol biosynthesis affected by HBV. These altered metabolic pathways are involved in the pathological process of not only hepatitis B, but also metabolic disorders, increasing the occurrence of complications, such as hepatocellular carcinoma and liver steatosis. Thus, a clearer understanding of the hepatic metabolic pathways affected by HBV and its pathogenesis is necessary to develop more novel therapeutic strategies targeting viral eradication. PMID- 27688656 TI - Gastrointestinal disorders associated with migraine: A comprehensive review. AB - Migraine is a recurrent and commonly disabling primary headache disorder that affects over 17% of women and 5%-8% of men. Migraine susceptibility is multifactorial with genetic, hormonal and environmental factors all playing an important role. The physiopathology of migraine is complex and still not fully understood. Many different neuropeptides, neurotransmitters and brain pathways have been implicated. In connection with the myriad mechanisms and pathways implicated in migraine, a variety of multisystemic comorbidities (e.g., cardiovascular, psychiatric and other neurological conditions) have been found to be closely associated with migraine. Recent reports demonstrate an increased frequency of gastrointestinal (GI) disorders in patients with migraine compared with the general population. Helicobacter pylori infection, irritable bowel syndrome, gastroparesis, hepatobiliary disorders, celiac disease and alterations in the microbiota have been linked to the occurrence of migraine. Several mechanisms involving the gut-brain axis, such as a chronic inflammatory response with inflammatory and vasoactive mediators passing to the circulatory system, intestinal microbiota modulation of the enteric immunological milieu and dysfunction of the autonomic and enteric nervous system, have been postulated to explain these associations. However, the precise mechanisms and pathways related to the gut-brain axis in migraine need to be fully elucidated. In this review, we survey the available literature linking migraine with GI disorders. We discuss the possible physiopathological mechanisms, and clinical implications as well as several future areas of interest for research. PMID- 27688655 TI - Regulation of the serotonin transporter in the pathogenesis of irritable bowel syndrome. AB - Serotonin (5-HT) and the serotonin transporter (SERT) have earned a tremendous amount of attention regarding the pathogenesis of irritable bowel syndrome (IBS). Considering that enteric 5-HT is responsible for the secretion, motility and perception of the bowel, the involvement of altered enteric 5-HT metabolism in the pathogenesis of IBS has been elucidated. Higher 5-HT availability is commonly associated with depressed SERT mRNA in patients with IBS compared with healthy controls. The expression difference of SERT between IBS patients and healthy controls might suggest that SERT plays an essential role in IBS pathogenesis, and SERT was expected to be a novel therapeutic target for IBS. Progress in this area has begun to illuminate the complex regulatory mechanisms of SERT in the etiology of IBS. In this article, current insights regarding the regulation of SERT in IBS are provided, including aspects of SERT gene polymorphisms, microRNAs, immunity and inflammation, gut microbiota, growth factors, among others. Potential SERT directed therapies for IBS are also described. The potential regulators of SERT are of clinical importance and are important for better understanding IBS pathophysiology and therapeutic strategies. PMID- 27688658 TI - Carbonic anhydrase enzymes II, VII, IX and XII in colorectal carcinomas. AB - AIM: To investigate expression of four alpha-carbonic anhydrases (CAs) in colorectal carcinomas (CRC) and compare the results with patients' survival. METHODS: Colorectal carcinoma samples from 539 CRC patients and control tissues were arranged as tissue microarrays and analyzed with antibodies against CA II, CA VII, CA IX, and CA XII. Intensity and extent of staining were both scored from 0 to 3 in each sample. These enzyme expression levels were then correlated to patients' survival and clinicopathological parameters, which were tumor differentiation grade and stage, site of tumor, patients' age, and gender. Kaplan Meier analysis and Cox regression hazard ratio model were used to analyze survival data. RESULTS: CA II and CA XII staining intensities correlated with patients' survival in that higher expression indicated poorer prognosis. In Cox regression analysis one unit increase in the CA II intensity increased the hazard ratio to 1.19 fold (CI: 1.04-1.37, P = 0.009). A significant correlation was also found when comparing CA XII staining intensity with survival of CRC patients (HR = 1.18, 95%CI: 1.01-1.38, P = 0.036). The extent of CA XII immunostaining did not correlate to the patients' survival (P = 0.242, Kaplan-Meier analysis). A significant interaction between age group and extent of the CA II staining was found. Increased extent of CA II had a significant hazard ratio among patients 65 years and older (1.42, 95%CI: 1.16-1.73, P = 0.0006). No correlations were found between CA VII (intensity P = 0.566, extent P = 0.495, Kaplan-Meier analysis), or CA IX (intensity P = 0.879, extent P = 0.315, Kaplan-Meier analysis) immunostaining results and survival, or the other parameters. CONCLUSION: The present findings indicate that CA II and CA XII could be useful in predicting survival in CRC. PMID- 27688660 TI - Etiology of chronic liver diseases in the Northwest of Italy, 1998 through 2014. AB - AIM: To assess the etiology of chronic liver diseases (CLD) from 1998 to 2014 at the outpatient clinic of Gastroenterology of the main hospital in Northwest of Italy among those dedicated to hepatology. METHODS: A random sample of charts of patients referred to for increased liver enzymes between January 1998 and December 2006, and between January 2012 and December 2014 were reviewed. Etiology search included testing for hepatitis B virus (HBV), hepatitis C virus (HCV), autoimmune hepatitis, primary biliary cirrhosis, Wilson's disease and hereditary hemocromatosis. A risky alcohol consumption was also considered. Non-alcoholic fatty liver disease (NAFLD) was diagnosed in patients with histological and/or ultrasound evidence of steatosis/steatohepatitis, and without other causes of CLD. RESULTS: The number of patients included was 1163. Of them, 528 (45%) had positivity for HCV and 85 (7%) for HBV. Among the virus-free patients, 417 (36%) had metabolic disorders whereas the remaining had history of alcohol abuse, less prevalent causes of CLD or concomitant conditions. In comparison to 1998-2000 (41%), a reduction of HCV alone-related cases was detected during the periods 2001-2003 (35%, OR = 0.75, 95%CI: 0.53-1.06), 2004-2006 (33%, OR = 0.70, 95%CI: 0.50-0.97) and 2012-2014 (31%, OR = 0.64, 95%CI: 0.46-0.91). On the contrary, in comparison to 1998-2000 (31%), metabolic-alone disorders increased in the period 2004-2006 (39%, OR = 1.37, 95%CI: 0.99-1.91) and 2012-2014 (41%, OR = 1.53, 95%CI: 1.09-2.16). The other etiologies remained stable. The increase of incidence of metabolic-alone etiology during the period 2004-2006 and 2012-2014 tended to be higher in older patients (>= 50 years) compared to younger (P = 0.058). CONCLUSION: In the Northwest of Italy, during this study period, the prevalence of HCV infection decreased notably whereas that of NAFLD increased. PMID- 27688659 TI - Hepatocyte isolation from resected benign tissues: Results of a 5-year experience. AB - AIM: To analyze retrospectively a 5-year experience of human hepatocyte isolation from resected liver tissues with benign disease. METHODS: We established a method of modified four-step retrograde perfusion to isolate primary human hepatocytes. Samples were collected from the resected livers of patients with intrahepatic duct calculi (n = 7) and liver hemangioma (n = 17). Only the samples weighing >= 15 g were considered suitable for hepatocyte isolation. By using the standard trypan blue exclusion technique, hepatocyte viability and yield were immediately determined after isolation. RESULTS: Twenty-four liver specimens, weighing 15-42 g, were immediately taken from the margin of the removed samples and transferred to the laboratory for hepatocyte isolation. Warm ischemia time was 5-35 min and cold ischemia time was 15-45 min. For the 7 samples of intrahepatic duct calculi, the method resulted in a hepatocyte yield of 3.49 +/- 2.31 * 10(6) hepatocytes/g liver, with 76.4% +/- 10.7% viability. The 17 samples of liver hemangioma had significantly higher yield of cells (5.4 +/- 1.71 * 10(6) cells/g vs 3.49 +/- 2.31 * 10(6) cells/g, P < 0.05) than the samples of intrahepatic duct calculi. However, there seems to be no clear difference in cell viability (80.3% +/- 9.67% vs 76.4% +/- 10.7%, P > 0.05). We obtained a cell yield of 5.31 +/- 1.87 * 10(6) hepatocytes/g liver when the samples weighed > 20 g. However, for the tissues weighing <= 20 g, a reduction in yield was found (3.08 +/- 1.86 * 10(6) cells/g vs 5.31 +/- 1.87 * 10(6) cells/g, P < 0.05). CONCLUSION: Benign diseased livers are valuable sources for large-number hepatocyte isolation. Our study represents the largest number of primary human hepatocytes isolated from resected specimens from patients with benign liver disease. We evaluated the effect of donor liver characteristics on cell isolation, and we found that samples of liver hemangioma can provide better results than intrahepatic duct calculi, in terms of cell yield. Furthermore, the size of the tissues can affect the outcome of hepatocyte isolation. PMID- 27688661 TI - Development of a prognostic scoring system for resectable hepatocellular carcinoma. AB - AIM: To develop a prognostic scoring system for overall survival (OS) of patients undergoing liver resection (LR) for hepatocellular carcinoma (HCC). METHODS: Consecutive patients who underwent curative LR for HCC between 2000 and 2013 were identified. The series was randomly divided into a training and a validation set. A multivariable Cox model for OS was fitted to the training set. The beta coefficients derived from the Cox model were used to define a prognostic scoring system for OS. The survival stratification was then tested, and the prognostic scoring system was compared with the European Association for the Study of the Liver (EASL)/American Association for the Study of Liver Diseases (AASLD) surgical criteria by means of Harrell's C statistics. RESULTS: A total of 917 patients were considered. Five variables independently correlated with post-LR survival: Model for End-stage Liver Disease score, hepatitis C virus infection, number of nodules, largest diameter and vascular invasion. Three risk classes were identified, and OS for the three risk classes was significantly different both in the training (P < 0.0001) and the validation set (P = 0.0002). Overall, 69.4% of patients were in the low-risk class, whereas only 37.8% were eligible to surgery according to EASL/AASLD. Survival of patients in the low-risk class was not significantly different compared with surgical indication for EASL/AASLD guidelines (77.2 mo vs 82.5 mo respectively, P = 0.22). Comparison of Harrell's C statistics revealed no significant difference in predictive power between the two systems (-0.00999, P = 0.667). CONCLUSION: This study established a new prognostic scoring system that may stratify HCC patients suitable for surgery, expanding surgical eligibility with respect to EASL/AASLD criteria with no harm on survival. PMID- 27688662 TI - Clinicopathological features of alpha-fetoprotein producing early gastric cancer with enteroblastic differentiation. AB - AIM: To investigate clinicopathological features of early stage gastric cancer with enteroblastic differentiation (GCED). METHODS: We retrospectively investigated data on 6 cases of early stage GCED and 186 cases of early stage conventional gastric cancer (CGC: well or moderately differentiated adenocarcinoma) who underwent endoscopic submucosal dissection or endoscopic mucosal resection from September 2011 to February 2015 in our hospital. GCED was defined as a tumor having a primitive intestine-like structure composed of cuboidal or columnar cells with clear cytoplasm and immunohistochemical positivity for either alpha-fetoprotein, Glypican 3 or SALL4. The following were compared between GCED and CGC: age, gender, location and size of tumor, macroscopic type, ulceration, depth of invasion, lymphatic and venous invasion, positive horizontal and vertical margin, curative resection rate. RESULTS: Six cases (5 males, 1 female; mean age 75.7 years; 6 lesions) of early gastric cancer with a GCED component and 186 cases (139 males, 47 females; mean age 72.7 years; 209 lesions) of early stage CGC were investigated. Mean tumor diameters were similar but rates of submucosal invasion, lymphatic invasion, venous invasion, and non-curative resection were higher in GCED than CGC (66.6% vs 11.4%, 33.3% vs 2.3%, 66.6% vs 0.4%, 83.3% vs 11% respectively, P < 0.01). Deep submucosal invasion was not revealed endoscopically or by preoperative biopsy. Histologically, in GCED the superficial mucosal layer was covered with a CGC component. The GCED component tended to exist in the deeper part of the mucosa to the submucosa by lymphatic and/or venous invasion, without severe stromal reaction. In addition, Glypican 3 was the most sensitive marker for GCED (positivity, 83.3%), immunohistochemically. CONCLUSION: Even in the early stage GCED has high malignant potential, and preoperative diagnosis is considered difficult. Endoscopists and pathologists should know the clinicopathological features of this highly malignant type of cancer. PMID- 27688664 TI - Pregnancy and inflammatory bowel disease: Do we provide enough patient education? A British study of 1324 women. AB - AIM: To examine patient knowledge and factors influencing knowledge about pregnancy in British women with inflammatory bowel disease (IBD). METHODS: This is a post hoc analysis of a study of female members of Crohn's and Colitis United Kingdom, aged 18-45 years who were sent an online questionnaire recording patient demographics, education, employment, marital status, and disease characteristics. Disease related pregnancy knowledge was recorded using Crohn's and colitis pregnancy knowledge score (CCPKnow). RESULTS: Of 1324 responders, 776 (59%) suffered from Crohn's disease, 496 (38%) from ulcerative colitis and 52 (4%) from IBD-uncategorised. CCPKnow scores were poor (0-7) in 50.8%, adequate (8-10) in 23.6%, good (11-13) in 17.7% and very good (>= 14) in 7.8%. Multiple linear regression analysis revealed that higher CCPKnow scores were independently associated with higher educational achievement (P < 0.001), younger age at diagnosis (P = 0.003) and having consulted a health care professional about pregnancy and IBD (P = 0.001). CONCLUSION: Knowledge was poor in 50%. Speaking with health-care professionals was a modifiable factor associated with better knowledge. This illustrates the importance of disease related pregnancy education. PMID- 27688663 TI - FOCUS: Future of fecal calprotectin utility study in inflammatory bowel disease. AB - AIM: To evaluate the perspective of gastroenterologists regarding the impact of fecal calprotectin (FC) on the management of patients with inflammatory bowel disease (IBD). METHODS: Patients with known IBD or symptoms suggestive of IBD for whom the physician identified that FC would be clinically useful were recruited. Physicians completed an online "pre survey" outlining their rationale for the test. After receipt of the test results, the physicians completed an online "post survey" to portray their perceived impact of the test result on patient management. Clinical outcomes for a subset of patients with follow-up data available beyond the completion of the "post survey" were collected and analyzed. RESULTS: Of 373 test kits distributed, 290 were returned, resulting in 279 fully completed surveys. One hundred and ninety patients were known to have IBD; 147 (77%) with Crohn's Disease, 43 (21%) Ulcerative Colitis and 5 (2%) IBD unclassified. Indications for FC testing included: 90 (32.2%) to differentiate a new diagnosis of IBD from Irritable Bowel Syndrome (IBS), 85 (30.5%) to distinguish symptoms of IBS from IBD in those known to have IBD and 104 (37.2%) as an objective measure of inflammation. FC levels resulted in a change in management 51.3% (143/279) of the time which included a significant reduction in the number of colonoscopies (118) performed (P < 0.001). Overall, 97.5% (272/279) of the time, the physicians found the test sufficiently useful that they would order it again in similar situations. Follow-up data was available for 172 patients with further support for the clinical utility of FC provided. CONCLUSION: The FC test effected a change in management 51.3% of the time and receipt of the result was associated with a reduction in the number of colonoscopies performed. PMID- 27688665 TI - Clinical guidelines of non-alcoholic fatty liver disease: A systematic review. AB - AIM: To perform a systematic review to grade guidelines and present recommendations for clinical management of non-alcoholic fatty liver disease (NAFLD). METHODS: A database search was conducted on PubMed for guidelines published before May 2016, supplemented by reviewing relevant websites. The Appraisal of Guidelines for Research and Evaluation (ARGEE) Instrument II was a tool designed to appraise the methodological rigor and transparency in which a clinical guideline is developed and it is used internationally. It was used to appraise the quality of guidelines in this study. The inclusion criteria include: clinical NAFLD guidelines for adults, published in English, and released by governmental agencies or key organizations. RESULTS: Eleven guidelines were included in this study. Since 2007, guidelines have been released in Asia (3 in China, 1 in South Korea, and 1 in Japan), Europe (1 in Italy), America (1 in United States and 1 in Chile) and three international agencies [European associations joint, Asia-Pacific Working Party and World Gastroenterology Organization (WGO)]. Using the ARGEE II instrument, we found US 2012 and Europe 2016 had the highest scores, especially in the areas of rigor of development and applicability. Additionally, Italy 2010 and Korea 2013 also presented comprehensive content, rigorous procedures and good applicability. And WGO 2014 offered various algorithms for clinical practice. Lastly, a practical algorithm for the clinical management was developed, based on the recommended guidelines. CONCLUSION: This is the first systematic review of NAFLD guidelines. It may yield insights for physicians and policy-makers in the development and application of guidelines. PMID- 27688666 TI - Diagnosis of colonic amebiasis and coexisting signet-ring cell carcinoma in intestinal biopsy. AB - Amebiasis is uncommon in developed countries. Several case reports in the literature emphasize that both the presenting symptoms and the radiological findings of colonic amebiasis closely resemble more common conditions, such as idiopathic inflammatory bowel disease and gastro-intestinal malignancy. We describe a unique case of colonic amebiasis (amebomas) coexisting with signet ring cell carcinoma of the ileocecal valve, the cecum and the appendix. Endoscopically, the ulcerated tumor was indistinguishable from the ulcerations and pseudotumors (amebomas) detected in the ascending colon. Histological examination of biopsy specimens revealed the pathognomonic features of protozoa with ingested erythrocytes in combination with signet-ring cell infiltration. The author concludes that amebiasis may not only mimic carcinoma but, rarely, may coexist with carcinoma in the same patient. Clinicians and pathologists should be aware of this possibility in order not to delay diagnosis and treatment of malignant disease.

PMID- 27688667 TI - Case of a tumor comprising gastric cancer and duodenal neuroendocrine tumor. AB - The present report describes a rare case of a tumor composed of early gastric cancer and a duodenal neuroendocrine tumor (NET). A 78-year-old woman underwent esophagogastroduodenoscopy at a local institution for screening of the upper gastrointestinal tract which revealed a protruded tumor through the pyloric ring from the pyloric antrum. The tumor was too large to treat at the facility; consequently, she was referred to our hospital for further management. Esophagogastroduodenoscopy with tumor biopsy of the lesion revealed the diagnosis of early gastric cancer. Endoscopic submucosal dissection was performed with sufficient free margins in both vertical and horizontal directions. Histopathological findings showed NET confined to the submucosal layer and covered by well-differentiated adenocarcinoma. Immunohistochemical stainings showed that the two lesions existed continuously. While the possibility of a collision cancer was considered, it was suggested that the two lesions existed continuously. Finally, the tumor was diagnosed as gastric cancer composed of duodenal NET G1, with a lymphatic invasion of NET component. PMID- 27688669 TI - Recombinant activated factor VII for uncontrolled bleeding postcardiac surgery. AB - A retrospective observational study to review the safety and efficacy of rFVIIa in persistent hemorrhage in post cardiac surgical patients. METHODS: Patients who had bleeding of 3 ml/kg/h or more for 2 consecutive hours after cardiac surgery were arranged into two groups; control group, who received conventional treatment and rFVIIa group, who received conventional treatment and rFVIIa. RESULTS: There was no significant difference in demographic and surgical characteristics of both groups. The chest tube output significantly decreased in the rFVIIa group compared to the other group 4 hours after admission {1.4 (IQR: 1-2.2) ml/kg/h vs 3.9 (IQR: 3.1-5.6) ml/kg/h; p = 0.004} and continues to be significant till 9 hours after CSICU admission {0.6 (IQR: 0.4-1.1) ml/kg/h vs 1.9 (IQR: 1.2-2.2) ml/kg/h; p = 0.04}. The median number of blood products units transfused to rFVIIa group was significantly lower compared to control group in the period from 3-12 hours after CSICU admission. 13 (5.5%) patients in rFVIIa group had Thromboembolic adverse events (TAE) compared to 7 (2.4%) patients in other group p = 0.27. 8 patients in the rFVIIa group needed reexploration compared to 19 patients in the other group, p = 0.01. No significant difference was noticed between the 2 groups regarding: new onset renal failure, median number of mechanical ventilator days, pneumonia, mediastinitis, ICU and hospital lengths of stay, survival at 30 days and at discharge. CONCLUSION: In this analysis, rFVIIa succefully reduced the chest tube bleeding and blood products transfused during severe post cardiac surgical bleeding. However, safety of rFVIIa remains unclear. Prospective controlled trials are still needed to confirm the role of rFVIIa. PMID- 27688670 TI - Mitral valve replacement for mitral stenosis: A 15-year single center experience. AB - OBJECTIVES: Mitral valve replacement with either a bioprosthetic or a mechanical valve is the treatment of choice for severe mitral stenosis. However, choosing a valve implant type is still a subject of debate. This study aimed to evaluate and compare the early and late outcomes of mitral valve replacement [mechanical (MMV) vs. bioprosthetic (BMV)] for severe mitral stenosis. METHODS: A retrospective cohort study was performed on data involving mitral stenosis patients who have undergone mitral valve replacement with either BMV (n = 50) or MMV (n = 145) valves from 1999 to 2012. Data were collected from the patients' records and follow-up through telephone calls. Data were analyzed for early and late mortality, New York Heart Association (NYHA) functional classes, stroke, pre- and postoperative echocardiographic findings, early and late valve-related complications, and survival. Chi-square test, logistic regression, Kaplan-Meier curve, and dependent proportions tests were some of the tests employed in the analysis. RESULTS: A total of 195 patients were included in the study with a 30 day follow-up echocardiogram available for 190 patients (97.5%), while 103 (53%) were available for follow-up over the telephone. One patient died early postoperatively; twelve patients died late in the postoperative period, six in the bioprosthesis group and six in the mechanical group. The late mortality had a significant association with postoperative stroke (p < 0.001) and postoperative NYHA Classes III and IV (p = 0.002). Postoperative NYHA class was significantly associated with age (p = 0.003), pulmonary disease (p = 0.02), mitral valve implant type (p = 0.01), and postoperative stroke (p = 0.02); 14 patients had strokes in the mechanical (9) and in the bioprosthetic (5) groups. NYHA classes were significantly better after the replacement surgeries (p < 0.001). BMV were significantly associated with worse survival (p = 0.03), worse NYHA postoperatively (p = 0.01), and more reoperations (p = 0.006). Survival was significantly better with MMV (p = 0.03). When the two groups were matched for age and mitral regurgitation, the analysis revealed that BMV were significantly associated with reoperations (p = 0.02) but not significantly associated with worse survival (p = 0.4) or worse NYHA (p = 0.4). CONCLUSION: MMV replacement in mitral stenosis patients is associated with a lower reoperation rate, but there was no difference in survival compared with BMV replacement. PMID- 27688671 TI - Quality of anticoagulation control among patients with atrial fibrillation: An experience of a tertiary care center in Saudi Arabia. AB - BACKGROUND: Atrial fibrillation (AF) is the most common chronic rhythm disorder. Patients with AF are at an increased risk of ischemic stroke. Therefore, optimal anticoagulation is essential to reduce the risk of stroke. The aim of this study was to assess the level of anticoagulation control achieved in patients with nonvalvular AF receiving medical care in a tertiary care hospital. METHODS: This was a retrospective cohort study in ambulatory care clinics at tertiary care hospital in Saudi Arabia. We included 110 nonvalvular AF patients treated with warfarin for at least 3 months at King Abdulaziz Medical City, Riyadh, Saudi Arabia, between May 1, 2012, and July 31, 2012. Thereafter, international normalized ratio results were collected for 1 year. Anticoagulation control was assessed by calculating time within therapeutic range (TTR) as per the Rosendaal method. RESULTS: The mean age was 64.9 +/- 16.5 years; 60.9% were female. The mean TTR was 59%. Almost one third of the patients (32.7%) had poor anticoagulation control; TTR of <50%. Poor anticoagulation control was significantly associated with higher CHADS2 (congestive heart failure, hypertension, age, diabetes, stroke) score (p = 0.043). TTR was not significantly different between men and women. Similarly, TTR was not associated with age or duration of anticoagulation. There was no adequate information to assess the effect of other factors such as diet, compliance, and level of education on anticoagulation. Thirty-one patients (28.2%) had a history of prior stroke. The overall quality of anticoagulation was not significantly different between patients with and without stroke, (TTR was 56.3% and 60.1%, respectively; p = 0.46). CONCLUSION: Quality of anticoagulation in patients with AF receiving medical care in a tertiary care hospital was suboptimal, with nearly 40% of the time spent outside the therapeutic range. Methods to improve anticoagulation control among patients with AF should be implemented. PMID- 27688672 TI - Predictors of cardio pulmonary resuscitation outcome in postoperative cardiac children. AB - BACKGROUND: Outcomes of cardiopulmonary resuscitation (CPR) in children with congenital heart disease have improved and many children have survived after an in-hospital cardiac arrest. AIM: The purpose of this study is to determine predictors of poor outcome after CPR in critical children undergoing cardiac surgery. METHODS: We conducted a retrospective chart review and data analysis of all CPR records and charts of all postoperative cardiac children who had a cardiac arrest and required resuscitation from 2011 until 2015. Demographic, pre operative, and postoperative data were reviewed and analyzed. RESULTS: During the study period, 18 postoperative pediatric cardiac patients had CPR. Nine of them had return of spontaneous circulation and survived (50%). On average CPR was required on the 3(rd) postoperative day. Univariate analysis demonstrated that poor outcome was associated with higher lactic acid measured 4-6 hours prior to arrest (p = 0.045; p = 0.02) coupled with higher heart rate (p = 0.031), lower O2 saturation (p = 0.01), and lower core body temperature (p = 0.019) recorded 6 hours before arrest. Nonsurvival required longer resuscitation duration and more epinephrine doses (p < 0.05). CONCLUSION: Higher heart rate, lower core body temperature, lower O2 saturation, and higher lactic acid measured 6 hours before arrest are possible predictors of poorer outcome and mortality following CPR in postoperative cardiac children. PMID- 27688673 TI - Arterial stiffness in metabolic syndrome. AB - Arterial stiffness is increasingly recognized as an important determinant of cardiovascular risk and may be directly involved in the process of atherosclerosis. As atherosclerosis leads to increased arterial resistance and decrease the flow propagation speed within the arterial lumen, a similar decrease in aortic flow propagation with increased downstream resistance is detected, so aortic flow propagation velocity AVP was evaluated in many studies as a new parameter of aortic stiffness. AIM: To measure arterial stiffness using the new parameter AVP and compare it to flow mediated dilatation FMD as a parameter of endothelial dysfunction in patients with metabolic syndrome MS. METHODS: AVP (assessed by transthoracic echocardiography) and FMD (assessed by brachial artery reactivity test) were measured in 100 patients with MS (Group 1) and were compared to 14 normal subjects (Group 2). RESULTS: Patients with MS had significantly lower values of AVP as compared to the normal subjects; 36 +/- 5 cm/s vs 57 +/- 5, p < 0.05, and lower FMD; 6% +/- 1 vs 17 +/- 3 p < 0.05 as well, there was significant correlations between AVP and FMD (r = 0.89, p < 0.001). CONCLUSION: Transthoracic echocardiographic determination of AVP is a simple practical method and correlates well with FMD in patients with MS. PMID- 27688674 TI - Single coronary artery from right aortic sinus in a very elderly patient. AB - In the absence of other associated cardiac anomalies, single coronary artery (SCA) per se is a rare anomaly detected during coronary angiography or autopsy. Various types of SCA detected during coronary angiography have already been described. We herein report a type of SCA originating from the right sinus of Valsalva, with the right circumflex, left circumflex, and left anterior descending coronary arteries arising from the proximal part of the SCA in a 76 year-old female patient. She developed ventricular fibrillation during coronary angiography, which calls for caution while performing a coronary angiogram in such patients. PMID- 27688675 TI - A continuous murmur following a nonpenetrating chest trauma. AB - We reported a rare case of non-penetrating chest trauma-induced fistula from the right sinus of Valsalva to the right heart chambers. The ruptured sinus of Valsalva aneurysm was diagnosed preoperatively and operated on successfully. The rarity of this case highlights the need for a precise preoperative diagnosis, the role of transthoracic echocardiography, and the importance of a prompt surgical management. PMID- 27688676 TI - Ortner's syndrome: Cardiovocal syndrome caused by aortic arch pseudoaneurysm. AB - 72-year-old hypertensive presented with two weeks history of left sided chest pain and hoarseness. Workup demonstrated a pseudoaneurysm in the lesser curvature of the distal aortic arch opposite the origin of the left subclavian artery from a penetrating atherosclerotic ulcer. Following a left carotid-subclavian bypass, endovascular stenting of the aorta was performed excluding the pseudoaneurysm. Patient had excellent angiographic results post-stenting. Follow up at 12 weeks demonstrated complete resolution of his symptoms and good stent position with no endo-leak. Ortner's syndrome describes vocal changes caused by cardiovascular pathology. It should be included in the differential diagnosis of patients with cardiovascular risk factors presenting with hoarseness. This case demonstrates the use of endovascular stents to treat the causative pathology with resolution of symptoms. In expert hands, it represents low risk, minimally invasive therapeutic strategy with excellent early results in patients who are high risk for open procedure. PMID- 27688677 TI - Aorto-left atrial fistula: Rare cause of acute cardiac failure in a previously healthy individual. AB - Complications of valvular infective endocarditis involving the peri-annular region puts the patient at a significantly high risk of adverse outcomes including heart failure and death. The "mitral-aortic intervalvular fibrosa" is relatively avascular and offers little resistance to the spread of abscesses, aneurysm, and fistula formation. Aorto-cavitary fistulous tract formation in the setting of native valve infective endocarditis is associated with higher rates of heart failure, ventricular septal defect, and atrioventricular block than nonruptured abscesses. Thus, a high index of suspicion is needed for rapid and accurate diagnosis, which can guide further management. A transesophageal echocardiogram is the preferred modality of investigation in such cases. Staphylococci are reported to be the most common pathogen involved. In addition to early antibiotic therapy, prompt surgical intervention might save lives in these scenarios. PMID- 27688679 TI - Pheochromocytoma presenting as an acute coronary syndrome complicated by acute heart failure: The challenge of a great mimic. AB - Pheochromocytoma is a rare neuroendocrine tumor with a highly variable clinical presentation. The serious and potentially lethal cardiovascular complications of these tumors are related to the effects of secreted catecholamines. We describe a case of a 50-year-old woman urgently admitted to our hospital because of symptoms and clinical and instrumental findings consistent with an acute coronary syndrome complicated by acute heart failure. Urgent coronary angiography showed normal coronary arteries. During her hospital stay, the recurrence of episodes characterized by a sudden increase in blood pressure, cold sweating, and nausea allowed us to hypothesize a pheochromocytoma. The diagnosis was confirmed by elevated levels of urinary catecholamines and by the finding of a left adrenal mass on magnetic resonance imaging. The patient underwent left adrenalectomy. Therefore, the initial diagnosis was critically reappraised and reviewed as a cardiac manifestation of a pheochromocytoma during catecholaminergic crisis.

AB - Brugada syndrome (BS), a life-threatening channelopathy associated with reduced inward sodium current due to dysfunctional sodium channels, is characterized by ST-segment elevation with downsloping "coved type" (type 1) or "saddle back" (type 2) pattern in V1-V3 precordial chest leads (1, 2). Brugada phenocopy, a term describing conditions inducing Brugada-like pattern of electrocardiogram (EKG) manifestations in patients without true BS, is an emerging condition (3). We describe a case series of Brugada phenocopy with hyponatremia. PMID- 27688680 TI - Cardiac resynchronization therapy and challenging coronary sinus angiography.

AB - Despite the abundance of research that supports the efficacy of exposure therapy for childhood anxiety disorders and OCD, negative views and myths about the harmfulness of this treatment are prevalent. These beliefs contribute to the underutilization of this treatment and less robust effectiveness in community settings compared to randomized clinical trials. Although research confirms that exposure therapy is efficacious, safe, tolerable, and bears minimal risk when implemented correctly, there are unique ethical considerations in exposure therapy, especially with children. Developing ethical parameters around exposure therapy for youth is an important and highly relevant area that may assist with the effective generalization of these principles.

AB - Objective To investigate attentional bias toward happy and sad faces in remitted depressed (RD) patients compared with healthy control (HC) subjects. Methods This cross-sectional study enrolled RD patients and sex- and age-matched HC subjects. Eye movement data were acquired for all study participants while free viewing a 2 * 2 matrix of emotional faces. The attentional bias toward different emotional faces and whether the attention maintenance components generated attentional bias in the RD patients were analysed by comparing the attentional modes of the RD group with the HC group. Results A total of 27 RD patients and 27 HC subjects were analysed in this study. The RD and HC groups exhibited no significant differences toward first fixation location and initial attentional maintenance. In later attentional maintenance, the RD group showed significantly less attentional bias toward happy faces, but there were no significant differences in their attentional bias toward sad faces, compared with the HC group. Conclusions This present study showed that the negative attentional bias of RD patients was successfully eased, but their positive attentional bias was still insufficient.

AB - Objective To investigate the effect and mechanism of action of metformin on proliferation of a human hypopharyngeal carcinoma cell line (FaDu). Methods FaDu cells were treated with metformin (25-125 mmol/l). Cell proliferation was evaluated via CCK-8 assay. Real-time quantitative reverse transcription polymerase chain reaction was used to evaluate microRNA (miR)-21-5p and PDCD4 (programmed cell death 4) expression. PDCD4 protein was quantified by Western blot. Results Metformin significantly inhibited FaDu cell proliferation in a dose (25-100 mmol/l) and time-dependent manner (12 h-36 h), significantly downregulated miR-21-5p, and upregulated PDCD4 mRNA and protein expression. Conclusions Metformin significantly inhibited FaDu cell proliferation , possibly via downregulation of miR-21-5p and upregulation of PDCD4.

AB - Objective To compare the effects of saddle, lumbar epidural and caudal blocks on anal sphincter tone using anorectal manometry. Methods Patients undergoing elective anorectal surgery with regional anaesthesia were divided randomly into three groups and received a saddle (SD), lumbar epidural (LE), or caudal (CD) block. Anorectal manometry was performed before and 30 min after each regional block. The degree of motor blockade of the anal sphincter was compared using the maximal resting pressure (MRP) and the maximal squeezing pressure (MSP). Results The study analysis population consisted of 49 patients (SD group, n = 18; LE group, n = 16; CD group, n = 15). No significant differences were observed in the percentage inhibition of the MRP among the three regional anaesthetic groups. However, percentage inhibition of the MSP was significantly greater in the SD group (83.6 +/- 13.7%) compared with the LE group (58.4 +/- 19.8%) and the CD group (47.8 +/- 16.9%). In all groups, MSP was reduced significantly more than MRP after each regional block. Conclusions Saddle block was more effective than lumbar epidural or caudal block for depressing anal sphincter tone. No differences were detected between lumbar epidural and caudal blocks.

AB - Objective To perform a meta-analysis of data from available published studies comparing laparoendoscopic single-site surgery varicocelectomy (LESSV) with conventional transperitoneal laparoscopic varicocele ligation. Methods A comprehensive data search was performed in PubMed and Embase to identify randomized controlled trials and comparative studies that compared the two surgical approaches for the treatment of varicoceles. Results Six studies were included in the meta-analysis. LESSV required a significantly longer operative time than conventional laparoscopic varicocelectomy but was associated with significantly less postoperative pain at 6 h and 24 h, a shorter recovery time and greater patient satisfaction with the cosmetic outcome. There was no difference between the two surgical approaches in terms of postoperative semen quality or the incidence of complications. Conclusion These data suggest that LESSV offers a well tolerated and efficient alternative to conventional laparoscopic varicocelectomy, with less pain, a shorter recovery time and better cosmetic satisfaction. Further well-designed studies are required to confirm these findings and update the results of this meta-analysis. PMID- 27688687 TI - Incidence and characteristics of hepatitis E virus infection in children in Assiut, Upper Egypt. AB - Objective To describe the characteristics of hepatitis E virus (HEV) infection in a cohort of children from Upper Egypt using data from a large multicentre prospective study of acute viral hepatitis (AVH). Methods Data from subjects aged 2-18 years with AVH or close contacts of those with AVH found to have asymptomatic AVH were included in the analysis. Information concerning medical history, clinical examination, liver function tests and screening for hepatotropic viruses was recorded and analysed. Results A total of 123 patients (73 boys, 50 girls) were included in the analysis. Of these, 33 (26.8%) had HEV infection, 17 (13.8%) had hepatitis A virus infection, 10 (8.1%) had hepatitis B virus infection, 14 (11.4%) had cytomegalovirus hepatitis, five (4.1%) had autoimmune hepatitis, 11 (8.9%) had hepatitis due to mixed viral infections and 33 (26.8%) had non A-E hepatitis. Overall, 38 (30.9%) had infection with HEV. HEV infection was significantly higher among those using underground wells as a water source compared with tap water. Liver enzymes were significantly raised in patients with non-HEV infection compared with those with HEV infection. Conclusions HEV is a significant cause of AVH among children in Upper Egypt. Contamination of drinking water appears to be a major source of infection. Screening for HEV should be considered in all Egyptian children with AVH. PMID- 27688688 TI - Incidence of insulin resistance and diabetes in patients with portosystemic shunts without liver dysfunction. AB - Objective To investigate the incidence of insulin resistance (IR) and diabetes in patients with chronic hepatic schistosomiasis japonica (HSJ) and portosystemic shunts (PSS). Methods Pre- and post-contrasted computed tomography images obtained from patients with HSJ and control subjects were reviewed by two radiologists who identified and graded any shunting vessels. Anthropometric measurements, hepatic enzymes, lipid profile, blood levels of albumin, glucose, insulin and homeostasis model assessment (HOMA-2) index of all participants were also assessed. Results Fifty-two patients with HSJ and 30 control subjects were involved in the study. The coronary, short gastric and perisplenic veins were the most common shunting vessels. There were no significant differences between patients and controls in terms of body mass index or liver function. The degree of shunting vessels, blood glucose, oral glucose tolerance test120/0, insulin, HOMA-2 index, glycosylated haemoglobin, cholesterol, high- and low-density lipoprotein, and C-reactive protein were significantly higher in the patients with IR. A positive correlation was found between the degree of the shunting vessels and the HOMA-2 index. Conclusions Patients with chronic HSJ and PSS without liver dysfunction had a high incidence of IR and diabetes. The study showed that PSS and IR are related and therefore patients with PSS should be screened for IR and vice versa. PMID- 27688689 TI - Evaluation of a liquid culture system in the detection of mycobacteria at an antituberculosis institution in China; A retrospective study. AB - Objective A retrospective study comparing the diagnostic performance of the BACTECTM MGITTM 960 system (M960 system; BD Worldwide, Franklin Lakes, NJ, USA) with Lowenstein-Jensen (L-J) culture to detect mycobacteria in sputum specimens from patients with suspected pulmonary tuberculosis (TB). Methods Sputum samples were analysed for the presence of acid-fast bacilli (AFB). Samples were inoculated into the M960 system and L-J culture. Positive cultures were examined for the presence of AFB. Results The M960 method detected significantly more positive samples than L-J culture (818/1676 [48.8%] vs 692/1676 [41.3%]). Using L J culture as reference, the sensitivity, specificity, positive predictive and negative predictive values of the M960 system were 91.0%, 76.1%, 77.0% and 92.2%, respectively. The time-to-detection of mycobacteria was 11.78 +/- 5.16 days for M960 and 24.17 +/- 8.73 days for L-J. Conclusions The M960 system had better diagnostic capability than L-J culture. Clinical value may be maximized by combining results from both methods.

PMID- 27688691 TI - Effects of acute cigarette smoking on total blood count and markers of oxidative stress in active and passive smokers. AB - BACKGROUND: Free radicals, as a product of cigarette smoke, are considered to have deleterious effects causing oxidative stress. Acute active smoking seems to be followed by transient leukocytosis and delayed increase in neutrophil activation. The aim of the present study was to investigate the oxidative status of smokers and passive non-smokers, as well as the impact that acute cigarette smoking has on hematological parameters. METHODS: Thirty-two healthy volunteers, 16 active smokers (Group A) aged 20-23 years and 16 age-matched, non-smokers (Group B), 18 women and 14 men in total, participated voluntarily in the study. All subjects did not have any food, drink, or cigarette smoking for eight hours before the study. Each time, two active smokers and two non-smokers were exposed simultaneously for half an hour to the smoke of two cigarettes smoked consecutively by the smokers. Blood was drawn before and after the exposure to cigarette smoke. Whole blood was analyzed immediately for total blood count parameters and serum was stored in -70(?)C until serum levels of malondialdehyde (MDA) and vitamin E (VitE), and total antioxidant capacity (TAC) were determined. RESULTS: No statistical significant difference was observed in the values of white blood cells and their subpopulations between the two groups and within the same group before and after exposure to cigarette smoke. In the group of smokers, granulocyte/lymphocyte ratio increased significantly, MDA levels showed significant elevation and protective VitE serum levels decreased significantly, whereas TAC was reduced, but not significantly, after the exposure. In the group of passive, non-smokers the results of the blood count parameters, MDA and VitE were similar to Group A, and there was a significant decrease in TAC, as well. Between the two groups, only hematocrit values and MDA levels differed significantly before the exposure to smoke, and no other significant difference was detected before or after the exposure, between active and passive smokers. CONCLUSIONS: Acute exposure to cigarette smoking affects hematological indexes and oxidative stress biomarkers negatively, in both active and passive smokers, with similar results. The outcome seems to be even worse in passive smokers regarding oxidative stress and antioxidant protection markers. Elimination of cigarette smoking could prevent the adverse effects for smokers, as well as for healthy non-smokers in their vicinity. Hippokratia 2015; 19 (4): 293-297. PMID- 27688692 TI - Effect of Ramadan fasting on metabolic markers, dietary intake and abdominal fat distribution in pregnancy. AB - BACKGROUND: The aim of this study is to evaluate the effect of Ramadan intermittent fasting on metabolic markers, dietary intake, anthropometric measurements, and abdominal visceral fat thickness (VFT) in pregnancy. METHODS: Seventy-eight healthy pregnant subjects who had fasted for at least 15 days during the month of Ramadan in 2012 and 2013 and 78 controls were included in this study. Metabolic markers, dietary intake, anthropometric measurements, and ultrasonographic VFT were calculated for each subject before and after Ramadan fasting. RESULTS: When before and after Ramadan values in the fasting group were compared, we found that daily protein intake was increased (p <0.001), but fat and carbohydrate intake remained unchanged. A significant reduction was observed in liquid consumption while the frequency of asymptomatic bacteriuria was increased. High-density lipoprotein significantly increased, and glycated hemoglobin, insulin, and homeostasis model index significantly decreased (p =0.005, p =0.01, p <0.001, and p =0.03, respectively). A significant increase in ferritin was found (p =0.02). No change was observed in subcutaneous fat thickness, while VFT significantly decreased (p =0.08, p =0.005). However, in the control group, only ferritin level increased. CONCLUSION: A combined change in the number and timing of meals and the portioning of the entire daily intake into only two meals per day may have beneficial metabolic effects and reduction in VFT during pregnancy.

AB - BACKGROUND: Kidney size may differ between healthy members of Balkan endemic nephropathy (BEN) and non-BEN families. The present study was designed to elucidate this, in comparison with values for BEN patients. METHODS: A total of 71 BEN patients (34 males, 64.4 +/- 12.0 years), 74 healthy BEN family members (39 males, 49.1 +/- 12.2 years), and 59 non-BEN family members (19 males, 49.2 +/ 12.3 years) were involved. We measured the longest craniocaudal length and minimal parenchymal thickness on each kidney of all examined subjects using ultrasound. RESULTS: No significant difference was found between the kidney length of healthy subjects from BEN (11.0 +/- 0.8 cm) and non-BEN families (10.9 +/- 0.8 cm), but kidneys were significantly longer than in BEN patients (9.9 +/- 1.3 cm). Minimal parenchymal thickness was similar in all three groups. When subjects from each group were divided according to estimated glomerular filtration rate (eGFR), kidney length of the healthy groups was significantly longer than in BEN patients both in stage 1 (p =0.039) and stage 2 (p =0.044) of chronic kidney disease. The parental history of BEN was not associated with kidney dimensions, eGFR, or urinary excretion of albumin and alpha1 microglobulin. CONCLUSION: Kidneys of BEN patients were significantly shorter than in healthy members of both BEN and non-BEN families, but no difference was found in kidney length and parenchymal thickness between healthy members of BEN and non-BEN families. No significant association was found between parental history of BEN and kidney size and function either in BEN patients or in healthy members from BEN families. Hippokratia 2015; 19 (4): 304-308. PMID- 27688694 TI - The prevalence of Factor V Leiden, prothrombin G20210A, MTHFR C677T and MTHFR A1298C mutations in healthy Turkish population. AB - BACKGROUND: Factor V Leiden (FVL), prothrombin gene (PT G20210A) and methylenetetrahydrofolate reductase (MTHFR) C677T polymorphisms are the main biomarkers used in the evaluation of tendency to venous thromboembolism. Our study aimed to investigate the distribution frequencies of these polymorphisms in healthy Turks living in the urban Yozgat region. MATERIAL AND METHODS: This study included 90 blood donor candidates. All the donors were apparently healthy, and there was no family relationship between them. Mutations including FVL, PT G20210A, and MTHFR (C677T, A1298C) were investigated in all participants. Screening of polymorphisms was carried out using the SNaPshot(r) multiplex system. RESULTS: There were 42 male and 48 female individuals with age range 17 78 years and mean age 47.5 +/- 13.6 years. The heterozygous FVL mutation was noted in 17 (10 male and seven female) donors (19%). FVL mutation was more frequently encountered in males than in females (23.8% vs. 12.5%). The heterozygous PT G20210A mutation was observed in five (5.5%) of the 90 (three male, two female) donors. The prevalence of homozygous polymorphisms of MTHFR C677T was 8.8% and of MTHFR A1298C 13.3%. On the other hand, four of the 90 participants (4.4%) carried none of these polymorphisms. CONCLUSION: This study showed that the prevalence of FVL, PT G20210A, MTHFR C677T and MTHFR A1298C polymorphisms is quite high, and the coexistence of FVL with other genotypes is not rare in a healthy Turkish population living in the Yozgat region. Of course, further detailed studies should be performed to support these findings. Hippokratia 2015; 19 (4): 309-313. PMID- 27688695 TI - The incidence of possible causes of membranoproliferative glomerulonephritis: a single-center experience. AB - BACKGROUND: Diagnosis of membranoproliferative glomerulonephritis (MPGN) is based on kidney biopsy findings: unique glomerular injury pattern and characteristic changes on light, electron microscopy and immunohistochemical analysis. The purpose of this study was to identify possible etiology and incidence of glomerular injury among patients with a diagnosed MPGN. MATERIALS AND METHODS: A retrospective analysis (years 2000-2014) of 81 clinical cases with a diagnosis of MPGN based on biopsy results was performed. Records were examined, and data about viral, bacterial infections, autoimmune and hematological diseases was collected. Test results of blood C3 and C4 factors of the complement system, and results of kidney biopsy immunohistochemical analysis were investigated. Statistical analysis was performed using Statistical Package for the Social Sciences and p value less than 0.05 was considered statistically significant. RESULTS: Study population consisted of 55 males (67.9%) and 26 females (32.1%). The average patients' age was 48.53 (standard deviation +/- 16.67) years. The identified etiology of MPGN was: idiopathic in 26 cases (32.10%), bacterial infections in 20 cases (24.69%), viral hepatitis in 16 cases (19.75%), autoimmune diseases in 11 cases (13.58%), and hematological diseases in eight cases (9.88%). Changes of the concentration of complement component C3 as well as component C4 were found; their concentration was decreased in 26 (32.1%) and 17 (20.99%) patients' respectively while concentration was within the normal range in 11 (13.58%) and 19 (23.46%) patients respectively. Immunohistochemistry results revealed immunoglobulin (Ig) deposits: C3+/Ig+ was found in 47 (58.02%) cases, C3-/Ig+ was found in 16 (19.75%) cases and in six (7.41%) cases test was not performed. The total number of immunoglobulin positive biopsies (C3+/Ig+ and C3-/Ig+, also called immune-complex mediated MPGN) was 63 (77.78%). Complement-mediated MPGN (C3+/Ig-) was less common and was diagnosed only in seven cases (8.64%). C3-/Ig- was found in five cases (6.17%). CONCLUSIONS: The leading cause of MPGN was idiopathic as well as bacterial infections. Complement component C3 concentration was mostly decreased. The incidence of normal and decreased concentration of the complement component C4 was almost equal. Most immunohistochemical deposits in kidney biopsy appeared to be C3/Ig positive, and it was observed in more than half of the cases of each MPGN etiological group. Hippokratia 2015; 19 (4): 314 318. PMID- 27688696 TI - The analgesic effect of apelin-13 and its mechanism of action within the nitric oxide and serotonin pathways. AB - BACKGROUND: Apelin has various effects on a lot of systems such as central nervous system and cardiovascular system. This study investigated the possible analgesic effects of apelin-13 using the hot-plate and the tail-flick thermal analgesia tests in rats. We also evaluated the mechanism underlying the analgesic effects of apelin-13 by pretreating with Nw-nitro-L-arginine methyl ester (L NAME) or ondansetron. MATERIAL & METHODS: Forty male rats were used. The rats were randomly assigned to five groups according to the treatment received: Group I: Control; Group II: Morphine; Group III: Apelin-13; Group IV: Apelin-13+L-NAME; Group V: Apelin-13+Ondansetron. Acute thermal pain was modeled using the hot plate and the tail-flick tests. RESULTS: During the hot-plate test, i.p. Morphine and apelin-13 administered at zero- and 30 min produced significantly greater analgesic effects compared to the control. When the nitric oxide pathway was inhibited by administration of L-NAME with apelin-13, the analgesic effect continued. When apelin-13 and ondansetron were co-administered, the analgesic effect of apelin-13 disappeared at zero- and 30 min. During the tail-flick test, at 30 min, significantly higher levels of analgesia were observed in both the morphine and apelin group (which did not differ from each other) compared to the control group. L-NAME co-administered with apelin-13 did not affect the degree of analgesia, but apelin-13 co-administered with ondansetron was associated with a greater reduction in analgesia compared to the other groups. CONCLUSION: Our results demonstrate that apelin-13 exerts an analgesic effect; co-administration of apelin-13 and ondansetron inhibits antinociception, an effect apparently mediated by five-hydroxytryptamine-three (5-HT3) receptors.

AB - BACKGROUND: Hypervolemia is a major risk factor for hypertension leading to cardiovascular diseases and also a frequent problem in maintenance hemodialysis (MHD) patients. Fluid overload (FO) can be determined by bioimpedance spectroscopy (BIS) which is a new, practical, and non-invasive method. We tried to determine FO by BIS in MHD patients and find out the relationship between FO and clinical features. MATERIAL AND METHODS: We studied 100 MHD patients aged between 20 and 85 years and undergoing hemodialysis three times weekly for minimum one year. By using BIS, we estimated FO and extracellular water (ECW). The patients who exhibited a FO/ECW ratio >15% were considered as FO. RESULTS: Twenty-nine (29.0%) patients had a FO/ECW ratio >15%. In the overhydrated group, the mean pre-hemodialysis systolic blood pressure was 153.3 +/- 20.0 mmHg and the mean diastolic blood pressure was 89.1 +/- 8.5 mmHg. These were significantly higher than in the non-overhydrated group (113.5 +/- 14.5 and 71.0 +/- 8.8, p <0.001). FO was significantly correlated with systolic and diastolic blood pressures (r =0.63, p <0.001 and r =0.59, p <0.001). The patients were divided into two groups, i.e. those with cardiothoracic index (CTI) of >0.5 and those with CTI of <=0.5. The median FO/ECW ratio was 0.11 L in the former group and 0.08 L in the latter group with a significant difference (p =0.006). CONCLUSIONS: Hypervolemia is associated with high blood pressure and left ventricular hypertrophy that should be treated effectively to prevent cardiovascular diseases in MHD patients. BIS is useful to assess hydration status in MHD patients. Hippokratia 2015; 19 (4): 324-331. PMID- 27688698 TI - Proton pump inhibitors and statins: a possible interaction that favors low density lipoprotein cholesterol reduction? AB - BACKGROUND: Proton pump inhibitors (PPIs) might influence the metabolism of cholesterol and statins in the liver. AIM: The impact of PPIs on low-density lipoprotein cholesterol (LDL-C) levels in statin-treated patients. METHODS: Retrospective observational study including consecutive statin-treated individuals followed for >=3 years in a university hospital lipid clinic. Demographic characteristics as well as clinical and laboratory data were recorded at baseline and the most recent visit. High, moderate and low-intensity statin therapy was defined according to the expected LDL-C reduction (>=50%, 30-50%, and <30%, respectively). We compared the LDL-C reduction in subjects receiving statin + PPI with those on statin alone and assessed the overall effect of PPI administration on LDL-C lowering. RESULTS: Of 648 statin-treated subjects, 7% were also taking a PPI. There was no difference between PPI vs. non-PPI group regarding baseline characteristics and intensity of lipid-lowering therapy. Stepwise linear regression analysis showed that PPI use was significantly associated with LDL-C reduction (b =0.104, p =0.005) along with baseline LDL-C levels (b =0.482, p <0.001), treatment with ezetimibe (b =0.198, p <0.001), presence of diabetes (b =0.168, p <0.001), compliance with treatment (b =0.205, p <0.001), intensity of statin treatment (b =0.101, p =0.005) and cardiovascular risk (b =0.082, p =0.049). Subjects receiving statin + PPI had a higher LDL-C reduction by 6.4% compared with those taking a statin alone (fully adjusted p =0.005). CONCLUSIONS: PPIs may modestly boost the statin-mediated LDL-C reduction. This effect should be confirmed by prospective clinical studies. Hippokratia 2015; 19 (4): 332-337. PMID- 27688699 TI - Sudden unexpected death in epilepsy: experience from a tertiary epilepsy centre in Cyprus with review of the literature. AB - BACKGROUND: Sudden unexpected death in epilepsy (SUDEP) affects 0.09-9.3 per 1,000 person-years depending on the population studied and constitutes the most common cause of death in people with epilepsy. The purpose of this study was to analyze epidemiological data of patients with SUDEP, identify possible risk factors in the population of a tertiary referral center and provide a review of the literature aiming to raise awareness of this phenomenon. METHODS: Data for this study originate from the records of the Cyprus Institute of Neurology and Genetics in Nicosia Cyprus. We performed a systematic review of patients with epilepsy who had died between 1997 and 2012 and identified those whose death circumstances met the definition of SUDEP. Information was collected regarding sex, age, type of seizures, anti-epileptic therapies, and circumstances of death. Ethical approval was obtained from the institutional medical ethics committee. RESULTS: Four hundred and forty four new patients were diagnosed with epilepsy among referrals to the epilepsy clinic and were followed to the end of the study period. Seven patients, six males, were identified who met criteria for SUDEP. The average age was 30 years. All patients had had either primary or secondary tonic-clonic seizures. Most were on polypharmacy, and two had Vagus Nerve Stimulation implanted. Most deaths were unwitnessed and nocturnal. The overall incidence rate for SUDEP in this population was 2.13 deaths/1000 person-years. Overall Cumulative Incidence (or lifetime risk) was calculated at 15.76 SUDEP deaths/1,000 patients. CONCLUSIONS: In our series, SUDEP was primarily a nocturnal and unwitnessed event that affected primarily young males. Among both males and females patients, 36.8% of all deaths were due to SUDEP. The major risk factor identified was the occurrence of generalized tonic-clonic seizures signifying that every effort should be made to control this type of seizures.

AB - BACKGROUND: Recent studies provide evidence that peripheral blood monocytes have the ability to differentiate into mesenchymal-like cells. The ability of cultured monocytes to differentiate and produce insulin in vitro is analysed in the present study. METHODS: Peripheral blood monocytes were isolated from healthy donors and cultivated for fourteen days. Growth factors and liraglutide were used to induce pancreatic differentiation in most of the cultures. The growth factors were: monocyte colony-stimulating factor, interleukin-3, hepatocyte growth factor and epidermal growth factor. The rest of the cultures were cultivated only with nutrient medium and human serum. Insulin levels were measured by an enzyme-linked immunosorbent assay. Cellular morphology was observed using optical and electron microscopy. Cell membrane receptors were detected by flow cytometry. RESULTS: Monocytes were able to synthesize and excrete high levels of insulin after seven days in culture. A further increase in the excretion of insulin was observed after fourteen days. Cells were also able to differentiate and synthesize insulin, even if no growth factors were added to the culture medium. Some of the cultures were able to excrete insulin in a glucose-dependent manner. Differentiated monocytes were connected to neighbouring cells with axons and resembled the morphology of mesenchymal, dendritic and myeloid-progenitor cells. Cells retained their mature receptors and simultaneously developed immature receptors on their membrane. CONCLUSIONS: Monocytes can acquire morphological properties of multipotent cells when they are cultivated under specific conditions in vitro. Differentiated monocytes are able to synthesize and excrete insulin. Hippokratia 2015; 19 (4): 344-351.

PMID- 27688702 TI - Evaluation and management of juvenile recurrent parotitis in children from northern Greece. AB - BACKGROUND: Juvenile Recurrent Parotitis (JRP) is a recurrent parotid inflammation of childhood. The aim of our study was to investigate the clinical, laboratory and imaging profile of children with JRP as well as to estimate the impact of siadendoscopy as a therapeutic tool in the clinical outcome of JRP. METHODS: Twenty-three children with JRP aged 3.5-16 years, were investigated. Twelve of them underwent sialendoscopy: seven aged <8 years under general and five aged >8 years under local anesthesia. RESULTS: The age at onset ranged from 2-15 years while the number of episodes from 2-8 per year. The autoantibody profile was negative in all patients, suggesting no evidence for autoimmune diseases. Antibody deficiency was found in two children. The imaging studies reveal an overall parotid swelling and intraparotid lymph nodes while microabscesses were present in 31% of the patients. Twelve patients who underwent sialendoscopy had a significant improvement in their clinical outcome; the mean episodes of JRP before sialendoscopy was 3.9/year and reduced to 0.4 at the post intervention year. CONCLUSION: Sialendoscopy represents an alternative and promising perspective in the management of JRP. Hippokratia 2015; 19 (4): 356 359.

AB - This paper analyzes the peristaltic flow of an incompressible micropolar nanofluid in a tapered asymmetric channel in the presence of thermal radiation and heat sources parameters. The rotation of the nanoparticles is incorporated in the flow model. The equations governing the nanofluid flow are modeled and exact solutions are managed under long wavelength and flow Reynolds number and long wavelength approximations. Explicit expressions of axial velocity, stream function, microrotation, nanoparticle temperature, and concentration have been derived. The phenomena of shear stress and trapping have also been discussed. Finally, the influences of various parameters of interest on flow variables have been discussed numerically and explained graphically. Besides, the results obtained in this paper will be helpful to those who are working on the development of various realms like fluid mechanics, the rotation, Brownian motion, thermophoresis, coupling number, micropolar parameter, and the nondimensional geometry parameters.

AB - Historically, classifications of arboviruses were based on serological techniques. Hence, collections of arbovirus isolates have been central to this process by providing the antigenic reagents for these methods. However, with increasing concern about biosafety and security, the introduction of molecular biology techniques has led to greater emphasis on the storage of nucleic acid sequence data over the maintenance of archival material. In this commentary, we provide examples of where archival collections provide an important source of genetic material to assist in confirming the authenticity of reference strains and vaccine stocks, to clarify taxonomic relationships particularly when isolates of the same virus species have been collected across a wide expanse of time and space, for future phenotypic analysis, to determine the historical diversity of strains, and to understand the mechanisms leading to changes in genome structure and virus evolution. PMID- 27688705 TI - LPS-induced expression of CD14 in the TRIF pathway is epigenetically regulated by sulforaphane in porcine pulmonary alveolar macrophages. AB - Pulmonary alveolar macrophages (AMs) are important in defense against bacterial lung inflammation. Cluster of differentiation 14 (CD14) is involved in recognizing bacterial lipopolysaccharide (LPS) through MyD88-dependent and TRIF pathways of innate immunity. Sulforaphane (SFN) shows anti-inflammatory activity and suppresses DNA methylation. To identify CD14 epigenetic changes by SFN in the LPS-induced TRIF pathway, an AMs model was investigated in vitro. CD14 gene expression was induced by 5 ug/ml LPS at the time point of 12 h and suppressed by 5 uM SFN. After 12 h of LPS stimulation, gene expression was significantly up regulated, including TRIF, TRAF6, NF-kappaB, TRAF3, IRF7, TNF-alpha, IL-1beta, IL 6, and IFN-beta. LPS-induced TRAM, TRIF, RIPK1, TRAF3, TNF-alpha, IL-1beta and IFN-beta were suppressed by 5 uM SFN. Similarly, DNMT3a expression was increased by LPS but significantly down-regulated by 5 uM SFN. It showed positive correlation of CD14 gene body methylation with in LPS-stimulated AMs, and this methylation status was inhibited by SFN. This study suggests that SFN suppresses CD14 activation in bacterial inflammation through epigenetic regulation of CD14 gene body methylation associated with DNMT3a. The results provide insights into SFN-mediated epigenetic down-regulation of CD14 in LPS-induced TRIF pathway inflammation and may lead to new methods for controlling LPS-induced inflammation in pigs. PMID- 27688706 TI - Identifying Significant Features in Cancer Methylation Data Using Gene Pathway Segmentation. AB - In order to provide the most effective therapy for cancer, it is important to be able to diagnose whether a patient's cancer will respond to a proposed treatment. Methylation profiling could contain information from which such predictions could be made. Currently, hypothesis testing is used to determine whether possible biomarkers for cancer progression produce statistically significant results. However, this approach requires the identification of individual genes, or sets of genes, as candidate hypotheses, and with the increasing size of modern microarrays, this task is becoming progressively harder. Exhaustive testing of small sets of genes is computationally infeasible, and so hypothesis generation depends either on the use of established biological knowledge or on heuristic methods. As an alternative machine learning, methods can be used to identify groups of genes that are acting together within sets of cancer data and associate their behaviors with cancer progression. These methods have the advantage of being multivariate and unbiased but unfortunately also rapidly become computationally infeasible as the number of gene probes and datasets increases. To address this problem, we have investigated a way of utilizing prior knowledge to segment microarray datasets in such a way that machine learning can be used to identify candidate sets of genes for hypothesis testing. A methylation dataset is divided into subsets, where each subset contains only the probes that relate to a known gene pathway. Each of these pathway subsets is used independently for classification. The classification method is AdaBoost with decision trees as weak classifiers. Since each pathway subset contains a relatively small number of gene probes, it is possible to train and test its classification accuracy quickly and determine whether it has valuable diagnostic information. Finally, genes from successful pathway subsets can be combined to create a classifier of high accuracy. PMID- 27688707 TI - Novel Biomarker Candidates for Colorectal Cancer Metastasis: A Meta-analysis of In Vitro Studies. AB - Colorectal cancer (CRC) is one of the most common and lethal cancers. Although numerous studies have evaluated potential biomarkers for early diagnosis, current biomarkers have failed to reach an acceptable level of accuracy for distant metastasis. In this paper, we performed a gene set meta-analysis of in vitro microarray studies and combined the results from this study with previously published proteomic data to validate and suggest prognostic candidates for CRC metastasis. Two microarray data sets included found 21 significant genes. Of these significant genes, ALDOA, IL8 (CXCL8), and PARP4 had strong potential as prognostic candidates. LAMB2, MCM7, CXCL23A, SERPINA3, ABCA3, ALDH3A2, and POLR2I also have potential. Other candidates were more controversial, possibly because of the biologic heterogeneity of tumor cells, which is a major obstacle to predicting metastasis. In conclusion, we demonstrated a meta-analysis approach and successfully suggested ten biomarker candidates for future investigation. PMID- 27688708 TI - DNA Methylation Heterogeneity Patterns in Breast Cancer Cell Lines. AB - Heterogeneous DNA methylation patterns are linked to tumor growth. In order to study DNA methylation heterogeneity patterns for breast cancer cell lines, we comparatively study four metrics: variance, I (2) statistic, entropy, and methylation state. Using the categorical metric methylation state, we select the two most heterogeneous states to identify genes that directly affect tumor suppressor genes and high- or moderate-risk breast cancer genes. Utilizing the Gene Set Enrichment Analysis software and the ConsensusPath Database visualization tool, we generate integrated gene networks to study biological relations of heterogeneous genes. This analysis has allowed us to contribute 19 potential breast cancer biomarker genes to cancer databases by locating "hub genes" - heterogeneous genes of significant biological interactions, selected from numerous cancer modules. We have discovered a considerable relationship between these hub genes and heterogeneously methylated oncogenes. Our results have many implications for further heterogeneity analyses of methylation patterns and early detection of breast cancer susceptibility. PMID- 27688709 TI - Evolution of Synonymous Codon Usage in the Mitogenomes of Certain Species of Bilaterian Lineage with Special Reference to Chaetognatha. AB - Chaetognatha is a minor phylum, comprising transparent marine invertebrates varying in size from 0.5 to 12 cm. The exact phylogenetic position of Chaetognatha in Metazoa has not been deciphered as some embryological characteristics place chaetognaths among deuterostomes and some morphological characteristics place these among protostomes. In this study, the major factors that drive synonymous codon usage bias (SCUB) in the mitogenomes of representative species of Chaetognatha and chosen species of other closely related phyla were analyzed. Spearman's rank correlation analyses of nucleotide contents suggested that mutational pressure and selection were acting in all examined mitogenomes but with varying intensities. The quantification of SCUB using effective number of codons vs. GC composition at the third codon position (GC3) plot suggested that mutational pressure due to GC compositional constraints might be one of the major influencing forces driving the SCUB in all chaetognaths except Sagitta enflata. However, neutrality plots revealed no significant correlation between GC3 and cumulative GC content at first and second codon positions (GC12) in all other species, except in Daphnia pulex. The parity rule 2 bias plot showed that significant compositional differences existed between C and G, as well as between A and T, contents in most of the protein-coding genes (PCGs) and, comparatively, A and T contents were used more proportionally than C and G contents in all chosen mitogenomes. Chi-square analysis revealed the presence of putative optimal codons in all species, except in S. enflata. The correspondence analysis identified that mutational pressure and selection act on the mitogenomes of the selected chaetognaths and other phyla with varying intensities. The cluster analysis based on relative synonymous codon usage (RSCU) values revealed that RSCU variations in the PCGs of mitogenomes of chaetognaths are more comparable with those of protostomes. Apart from mutational pressure and selection, certain unknown selective forces might be acting on the PCGs in the analyzed mitogenomes as the phenomenon of SCUB could not be explained by mutational pressure, by selection, or by both. PMID- 27688710 TI - A Single-Cell Platform for Monitoring Viral Proteolytic Cleavage in Different Cellular Compartments. AB - Infectious diseases affect human health despite advances in biomedical research and drug discovery. Among these, viruses are especially difficult to tackle due to the sudden transfer from animals to humans, high mutational rates, resistance to current treatments, and the intricacies of their molecular interactions with the host. As an example of these interactions, we describe a cell-based approach to monitor specific proteolytic events executed by either the viral-encoded protease or by host proteins on the virus. We then emphasize the significance of examining proteolysis within the subcellular compartment where cleavage occurs naturally. We show the power of stable expression, highlighting the usefulness of the cell-based multiplexed approach, which we have adapted to two independent assays previously developed to monitor (a) the activity of the HIV-1-encoded protease or (b) the cleavage of the HIV-1-encoded envelope protein by the host. Multiplexing was achieved by mixing cells each carrying a different assay or, alternatively, by engineering cells expressing two assays. Multiplexing relies on the robustness of the individual assays and their clear discrimination, further enhancing screening capabilities in an attempt to block proteolytic events required for viral infectivity and spread. PMID- 27688711 TI - Vitamin D Deficiency in Medical Inpatients: A Retrospective Study of Implications of Untreated Versus Treated Deficiency. AB - Vitamin D deficiency and insufficiency may further increase fracture risk in patients with decreased bone mineral density. A cross-sectional study on serum vitamin D concentrations in medical inpatients was conducted at Bassetlaw District General Hospital between April 2014 and January 2015 (10 months), and the relationship of serum vitamin D concentrations with calcium and alkaline phosphatase was evaluated. 25-Hydroxyvitamin D immunoassays were used and analyzed in the local laboratory. The total number of patients analyzed was 200, age range 18-99 years, with mean age of 76 years. The most common presentation was found to be fall/collapse. The following cutoff points for serum vitamin D were used: levels <=30 nmol/L for severe deficiency, >30-50 nmol/L for moderate deficiency, >50-75 nmol/L for mild deficiency, and anything above 75 nmol/L as normal. Of the 209 participants examined, 78 (37.3%) participants had mild vitamin D deficiency, 54 (25.8%) participants had moderate vitamin D deficiency, 68 (32.5%) participants had severe vitamin D deficiency, and 9 (4.3%) participants with low vitamin D levels died during their admission. Of the 122 moderate/severe patients, 70 (57.4%) patients had their vitamin D deficiency treated, according to local Trust guidelines. The study found no relationship between serum calcium levels and vitamin D deficiency, whereas patients' alkaline phosphatase levels were found to be higher with increased severity of vitamin D deficiency. The study examined the implications of untreated severe/moderate vitamin D deficiency compared to treated deficiency, in terms of the frequency of readmission with similar complaints. It was found that the rate of readmission within one year in patients who were not treated was 57%, compared to 48% in patients whose vitamin D deficiency was treated. Presenting after falls was a recurring theme. It was concluded that even if moderate vitamin D deficiency can be asymptomatic, it is important to correct it as it can have an impact on morbidity and readmission rates in the long term. PMID- 27688712 TI - Standardized Follow-up of Patients with Symptomatic Knee Osteoarthritis Treated with a Single Intra-articular Injection of a Combination of Cross-Linked Hyaluronic Acid and Mannitol. AB - OBJECTIVES: The objective of this study is to obtain pilot data from daily practice conditions of a viscosupplement made of a cross-linked high-molecular weight hyaluronic acid (HA) combined with mannitol in patients with knee osteoarthritis (KOA). METHODS: The data of 40 consecutive patients, 29 women and 11 men, who were prospectively followed up for 6 months, using a standardized procedure, were retrospectively analyzed. All patients have received a single intra-articular injection of HAnox-M-XL (4.4 mL), viscosupplement made of a cross linked HA (16 mg/mL) + mannitol (35 mg/mL), in the target knee. The primary outcome was safety. The secondary end points included 3- and 6-month change in the WOMAC pain (0-50) and WOMAC total (0-240) and patient's global assessment (PGA). Patient's self-assessment of treatment efficacy (0-3) and analgesic consumption were obtained at months 3 and 6. An intent-to-treat analysis was performed. RESULTS: Mean (SD) age was 60.7 (13.9) years, and mean BMI was 28.6 (5.0). Kellgren-Lawrence radiological grade was I/II and III/IV in 13 and 27 of the subjects, respectively. The average WOMAC pain and WOMAC total scores at baseline were 21.5 (9.8) and 89.9 (42.8), respectively. Thirty-nine patients completed the follow-up. HAnox-M-XL was well tolerated; two patients experienced knee pain after injection, which resolved within three days. No treatment-related severe adverse event was reported. Mean (SD) variations in WOMAC pain and WOMAC total scores were -8.2 (8.9) and -38.4 (35.6), respectively, at month 6 (P = 0.001). PGA decreased from 5.5 (2.0) to 3.0 (2.2) (P = 0.006). Efficacy was rated as good or very good in 76.9% of the cases. Most of the regular analgesics users decreased their consumption. CONCLUSION: Treatment with one injection of 4.4 mL HAnox-M-XL is effective to alleviate KOA symptoms over six months, without safety concern. Controlled trials are needed to confirm these pilot data.

PMID- 27688716 TI - Successful Implementation of a Multicountry Clinical Surveillance and Data Collection System for Ebola Virus Disease in West Africa: Findings and Lessons Learned. AB - BACKGROUND: The 2014 outbreak of Ebola virus disease (EVD) in West Africa was the largest ever recorded. Starting in September 2014, International Medical Corps (IMC) managed 5 Ebola treatment units (ETUs) in Liberia and Sierra Leone, which cumulatively cared for about 2,500 patients. We conducted a retrospective cohort study of patient data collected at the 5 ETUs over 1 year of operations. METHODS: To collect clinical and epidemiological data from the patient care areas, each chart was either manually copied across the fence between the high-risk zone and low-risk zone, imaged across the fence, or imaged in the high-risk zone. Each ETU's data were entered into a separate electronic database, and these were later combined into a single relational database. Lot quality assurance sampling was used to ensure data quality, with reentry of data with high error rates from imaged records. RESULTS: The IMC database contains records on 2,768 patient presentations, including 2,351 patient admissions with full follow-up data. Of the patients admitted, 470 (20.0%) tested positive for EVD, with an overall case fatality ratio (CFR) of 57.0% for EVD-positive patients and 8.1% for EVD-negative patients. Although more men were admitted than women (53.4% vs. 46.6%), a larger proportion of women were diagnosed EVD positive (25.6% vs. 15.2%). Diarrhea, red eyes, contact with an ill person, and funeral attendance were significantly more common in patients with EVD than in those with other diagnoses. Among EVD positive patients, age was a significant predictor of mortality: the highest CFRs were among children under 5 (89.1%) and adults over 55 (71.4%). DISCUSSION: While several prior reports have documented the experiences of individual ETUs, this study is the first to present data from multiple ETUs across 2 countries run by the same organization with similar clinical protocols. Our experience demonstrates that even in austere settings under difficult conditions, it is possible for humanitarian organizations to collect high-quality clinical and epidemiologic data during a major infectious disease outbreak. PMID- 27688717 TI - Intensive Group Learning and On-Site Services to Improve Sexual and Reproductive Health Among Young Adults in Liberia: A Randomized Evaluation of HealthyActions. AB - INTRODUCTION: Young Liberians, particularly undereducated young adults, face substantial sexual and reproductive health (SRH) challenges, with low uptake of contraceptive methods, high rates of unintended pregnancy, and low levels of knowledge about HIV status. The purpose of this study was to assess the impact of a 6-day intensive group learning intervention combined with on-site SRH services (called HealthyActions) among out-of-school young adults, implemented through an existing alternative education program, on uptake of contraception and HIV testing and counseling (HTC). METHODS: The intervention was implemented among young women and men ages 15-35 who were enrolled in alternative basic education learning sites in 5 counties of Liberia. We conducted a randomized evaluation to assess program impact. Baseline data were collected in January-March 2014, and endline data in June-July 2014. Key outcomes of condom use, contraceptive use, and HTC were estimated with difference-in-difference models using fixed effects. All analyses were conducted in Stata 13. RESULTS: We assessed outcomes for 1,157 learners at baseline and 1,052 learners at endline, across 29 treatment and 26 control sites. After adjusting for potential confounders, learners in the HealthyActions intervention group were 12% less likely to report never using a condom with a regular partner over the last month compared with the control group (P = .02). Female learners who received HealthyActions were 13% more likely to use any form of modern contraception compared with learners in control sites (P<.001), with the greatest increase in the use of contraceptive implants. Learners in HealthyActions sites were 45% more likely to have received HTC (P<.001). CONCLUSION: Providing intensive group learning in a supportive environment coupled with on-site health services improved SRH outcomes among participating learners. The focus of HealthyActions on participatory learning for low-literacy populations presents an adaptable solution for health programming across Liberia and the region. PMID- 27688718 TI - Progress in Harmonizing Tiered HIV Laboratory Systems: Challenges and Opportunities in 8 African Countries. AB - In 2014, the Joint United Nations Programme on HIV/AIDS released its 90-90-90 targets, which make laboratory diagnostics a cornerstone for measuring efforts toward the epidemic control of HIV. A data-driven laboratory harmonization and standardization approach is one way to create efficiencies and ensure optimal laboratory procurements. Following the 2008 "Maputo Declaration on Strengthening of Laboratory Systems"-a call for government leadership in harmonizing tiered laboratory networks and standardizing testing services-several national ministries of health requested that the United States Government and in-country partners help implement the recommendations by facilitating laboratory harmonization and standardization workshops, with a primary focus on improving HIV laboratory service delivery. Between 2007 and 2015, harmonization and standardization workshops were held in 8 African countries. This article reviews progress in the harmonization of laboratory systems in these 8 countries. We examined agreed-upon instrument lists established at the workshops and compared them against instrument data from laboratory quantification exercises over time. We used this measure as an indicator of adherence to national procurement policies. We found high levels of diversity across laboratories' diagnostic instruments, equipment, and services. This diversity contributes to different levels of compliance with expected service delivery standards. We believe the following challenges to be the most important to address: (1) lack of adherence to procurement policies, (2) absence or limited influence of a coordinating body to fully implement harmonization proposals, and (3) misalignment of laboratory policies with minimum packages of care and with national HIV care and treatment guidelines. Overall, the effort to implement the recommendations from the Maputo Declaration has had mixed success and is a work in progress. Program managers should continue efforts to advance the principles outlined in the Maputo Declaration. Quantification exercises are an important method of identifying instrument diversity, and provide an opportunity to measure efforts toward standardization. PMID- 27688719 TI - Improving the Quality of Postabortion Care Services in Togo Increased Uptake of Contraception. AB - High-quality postabortion care (PAC) services that include family planning counseling and a full range of contraceptives at point of treatment for abortion complications have great potential to break the cycle of repeat unintended pregnancies and demand for abortions. We describe the first application of a systematic approach to quality improvement of PAC services in a West African country. This approach-IntraHealth International's Optimizing Performance and Quality (OPQ) approach-was applied at 5 health care facilities in Togo starting in November 2014. A baseline assessment identified the following needs: reorganizing services to ensure that contraceptives are provided at point of treatment for abortion complications, before PAC clients are discharged; improving provider competencies in family planning services, including in providing long-acting reversible contraceptive implants and intrauterine devices; ensuring that contraceptive methods are available to all PAC clients free of charge; standardizing PAC registers and enhancing data collection and reporting systems; enhancing internal supervision systems at facilities and teamwork among PAC providers; and engaging PAC providers in community talks. Solutions devised and applied at the facilities during OPQ resulted in significant increases in contraceptive counseling and uptake among PAC clients: During the 5-month baseline period, 31% of PAC clients were counseled, while during the 13-month intervention period, 91% were counseled. Of all PAC clients counseled during the baseline period, 37% accepted a contraceptive, compared with 60% of those counseled during the intervention period. Oral contraceptive pills remained the most popular method during both periods, yet uptake of implants increased significantly during the intervention period-from 4% to 27% of those accepting contraceptives. This result demonstrates that the solutions applied maintained method choice while expanding access to underused long-acting reversible contraceptives. OPQ shows great potential for sustainability and scale in Togo and for application in similar contexts where the health system struggles to offer safe, high-quality, accessible PAC services. PMID- 27688720 TI - Use of the World Health Organization's Medical Eligibility Criteria for Contraceptive Use Guidance in sub-Saharan African Countries: A Cross-Sectional Study. AB - Given recent updates to the postpartum contraception recommendations in the fifth edition of the Medical Eligibility Criteria for Contraceptive Use (MEC), published by the World Health Organization (WHO), the purpose of this qualitative study was to assess the extent to which national family planning policies in sub Saharan African countries are in agreement with the WHO MEC, particularly with regard to postpartum contraceptive use. WHO headquarters sent questionnaires to country-level focal points to complete with their Ministry of Health counterparts. Between February and May 2016, 23 of 32 (72%) surveys were completed. All respondents reported that their countries had used the MEC document in the past, with most reporting that they had used the guidance as a reference (n = 20, 87%), for training purposes (n = 19, 83%), to change clinical practices (n = 17, 74%), and to develop national policies (n = 16, 70%). While many respondents (16, 70%) indicated their countries already include immediate postpartum intrauterine device insertion among breastfeeding women in their family planning policies, few reported currently allowing use of progestogen-only pills (n = 8, 35%) or implants (n = 8, 35%) during the immediate postpartum period (i.e., less than 48 hours after delivery) for breastfeeding women. A higher percentage of respondents indicated their countries allowed breastfeeding women the option of progestogen-only pills (n = 16, 70%) and implants (n = 13, 57%) between 48 hours and 6 weeks postpartum. Findings from this baseline assessment suggest that many countries may benefit from training and policy formulation support to adapt both new WHO MEC updates as well as existing recommendations from previous MEC revisions into national family planning guidelines. PMID- 27688721 TI - Notch signalling pathway as an oncogenic factor involved in cancer development. AB - Notch signalling is an evolutionarily conserved signalling pathway, which plays a significant role in a wide array of cellular processes including proliferation, differentiation, and apoptosis. Nevertheless, it must be noted that Notch is a binary cell fate determinant, and its overexpression has been described as oncogenic in a broad range of human malignancies. This finding led to interest in therapeutically targeting this pathway especially by the use of GSIs, which block the cleavage of Notch at the cell membrane and inhibit release of the transcriptionally active NotchIC subunit. Preclinical cancer models have clearly demonstrated that GSIs suppress the growth of such malignancies as pancreatic, breast, and lung cancer; however, GSI treatment in vivo is associated with side effects, especially those within the gastrointestinal tract. Although intensive studies are associated with the role of gamma-secretase in pathological states, it should be pointed out that this complex impacts on proteolytic cleavages of around 55 membrane proteins. Therefore, it is clear that GSIs are highly non specific and additional drugs must be designed, which will more specifically target components of the Notch signalling. PMID- 27688724 TI - Radiation-induced caries as the late effect of radiation therapy in the head and neck region. AB - Overall improvement in the nationwide system of medical services has consequently boosted the number of successfully treated patients who suffer from head and neck cancer. It is essential to effectively prevent development of radiation-induced caries as the late effect of radiation therapy. Incidence and severity of radiationinduced changes within the teeth individually vary depending on the patient's age, actual radiation dose, size of radiation exposure field, patient's general condition and additional risk factors. Inadequately managed treatment of caries may lead to loss of teeth, as well as prove instrumental in tangibly diminishing individual quality of life in patients. Furthermore, the need to have the teeth deemed unyielding or unsuitable for the application of conservative methods of treatment duly extracted is fraught for a patient with an extra hazard of developing osteoradionecrosis (ORN), while also increasing all attendant therapeutic expenditures. The present paper aims to offer some practical insights into currently available methods of preventing likely development of radiation induced caries. PMID- 27688723 TI - Particular aspects in the cytogenetics and molecular biology of salivary gland tumours - current review of reports. AB - Salivary gland tumours are a group of lesions whose heterogeneity of biological and pathological features is widely reflected in the molecular aspect. This is demonstrated by an increasing number of studies in the field of genetics of these tumours. The aim of this study was to collect the most significant scientific reports on the cytogenetic and molecular data concerning these tumours, which might facilitate the identification of potential biomarkers and therapeutic targets. The analysis covered 71 papers included in the PubMed database. We focused on the most common tumours, such as pleomorphic adenoma, Warthin tumour, mucoepidermoid carcinoma, and others. The aim of this study is to present current knowledge about widely explored genotypic alterations (such as PLAG1 gene in pleomorphic adenoma or MECT1 gene in mucoepidermoid carcinoma), and also about rare markers, like Mena or SOX10 protein, which might also be associated with tumourigenesis and carcinogenesis of these tumours. PMID- 27688725 TI - Impact of mTOR expression on clinical outcome in paediatric patients with B-cell acute lymphoblastic leukaemia - preliminary report. AB - AIM OF THE STUDY: To characterise expression of mTOR (mammalian target of rapamycin) in childhood B-cell acute lymphoblastic leukaemia (ALL), and to evaluate a possible link between mTOR and clinical characteristics. MATERIAL AND METHODS: The examined group consisted of 21 consecutive patients, aged 1-18 years, diagnosed with B-cell ALL in 2010, and 10 relapsed B-cell ALL patients diagnosed for the first time between 2009 and 2011, who developed relapse before 2014. All subjects were treated in the Department of Paediatric Haematology and Oncology of the Medical University of Warsaw according to the ALL-IC BFM 2002 Protocol. We evaluated mTOR and phospho-mTOR expression by immunohistochemistry using rabbit monoclonal antibodies. RESULTS: mTOR expression was found to be significantly associated with the risk of relapse and was more frequent in ALL recurrence. No significant relationship was detected between mTOR expression and other features of high-risk disease in paediatric ALL. CONCLUSIONS: mTOR activity could be considered a high-risk feature in paediatric B-cell ALL. Expression of mTOR kinase is observed remarkably more frequently in disease recurrence than at first diagnosis, indicating higher proliferative and survival potential of leukaemic cells in relapse. Routine analysis of mTOR activity could be performed to select patients that may potentially benefit from mTOR inhibitors (MTI) treatment. PMID- 27688722 TI - The potential therapeutic applications and prognostic significance of metastasis associated in colon cancer-1 (MACC1) in cancers. AB - The metastasis-associated in colon cancer-1 (MACC1) gene was identified in 2009. Expression of MACC1 was found to be significantly upregulated in primary and metastatic colon carcinomas compared to normal tissues or adenomas. The induction of MACC1 occurs at the crucial step of transition from a benign to a malignant phenotype. The aim of this review was to summarise current results of non clinical and clinical studies on the role of MACC1 in the carcinogenesis and progression of cancer, as well its potential therapeutic and prognostic significance. The gene encoding the HGF receptor MET is a transcriptional target of MACC1. In addition to promoting the proliferation, invasion, and migration of colon cancer cells in cell culture and tumour growth and metastasis in mouse models, MACC1 also contributes to carcinogenesis and progression of colorectal cancer through the beta-catenin signalling pathway and mesenchymal-epithelial transition. MACC1 knockdown with si/sh RNA was investigated in cell lines of different types of cancer. MACC1 is a promising therapeutic target for antitumour and antimetastatic intervention strategies for cancers. Here, it is presented as a potential independent prognostic indicator of reduced overall survival as well as of the occurrence of distant metastasis in patients with different types of cancer. PMID- 27688726 TI - Primary mediastinal B-cell lymphoma - metabolic and anatomical features in 18FDG PET/CT and response to therapy. AB - AIM OF THE STUDY: Determining the role of PET/CT imaging in the evaluation of treatment efficacy in primary mediastinal B-cell lymphoma (PMBCL). MATERIAL AND METHODS: Retrospective analysis of seven PMBCL patients, treated at the University Hospital in Krakow, with interim PET/CT after the third course of chemo-immunotherapy.The analysis was based on the calculation of exact tumour volume and metabolic activity, compared with initial values (directly after diagnosis). RESULTS: Patients (five females, two males, average age 26.2 years, range 18-40 years), in clinical stage IIBX at diagnosis, were treated with eight cycles of R-CHOP-14 regimen, with radiotherapy consolidation (7/7) and central nervous system prophylaxis (6/7). The observed decrease in tumour volume between the initial staging and the interim PET ranged 72-89%. The mean DeltaSUVmax reduction between initial (when available) and interim PET was 87% (range 84 89%). In 3/7 cases in the interim PET/CT, the uptake of the tumour was higher than the liver (Deauville Criteria score 4-5), and in 4/7 it was lower than the liver but higher than mediastinal blood pool structures (score 3 according to Deauville Criteria). After a median follow-up of 58 months - OS and EFS is 100%. CONCLUSIONS: The excellent clinical outcome in the study group corresponds with very good metabolic and volumetric response in the interim PET. The DeltaSUVmax seems to be easier in implementation and has a more significant impact than other measurements. PMID- 27688727 TI - Total antioxidant status in lung cancer is associated with levels of endogenous antioxidants and disease stage rather than lifestyle factors - preliminary study. AB - AIM OF THE STUDY: Decreased total antioxidant capacity (TAC) has been reported in different neoplasms, including lung cancer. However, no study concerning the relationship between endogenous antioxidants, lifestyle factors, and TAC has been conducted among lung cancer patients. The purpose of the study was to investigate the associations between endogenous antioxidants, severity of disease, lifestyle factors, and TAC in lung cancer patients. MATERIAL AND METHODS: The study was conducted among 59 lung cancer patients. The levels of total antioxidant status (ATBS method), endogenous antioxidants, and C-reactive protein were measured in patients' sera automatically. Dietary habits of the subjects were evaluated based on the Food Frequency Questionnaire (FFQ) on the day of admission to hospital. RESULTS: We found a positive correlation between serum albumin, uric acid (UA), and TAC and a negative correlation between CRP and TAC. Moreover, TAC was significantly positively associated with disease stage. We did not find any significant relationship between the frequency of selected food consumption and TAC in lung cancer patients, except for a positive correlation between the frequency of refined cereal products consumption and TAC level. Smoking status did not correlate with TAC. CONCLUSIONS: Total antioxidant status of lung cancer patients results from their disease stage and levels of endogenous antioxidants rather than from lifestyle factors. The lack of influence of diet and smoking on the TAC presumably result from disturbed homeostasis in which cancer, while developing, could determine the redox state to a greater extent than lifestyle factors. PMID- 27688728 TI - Evaluation of a newly discovered breast cancer susceptibility locus at 6q25.1 in Iranian Azari-Turkish women. AB - AIM OF THE STUDY: A recent breast cancer genome-wide association study (GWAS) identified single-nucleotide polymorphism (SNP) rs2046210 on 6q25.1 showing a strong association with breast cancer risk. Numerous association studies have been conducted to investigate the relationship between this polymorphism and breast cancer risk in various populations. There have been conflicting reports about the association of this locus with breast cancer risk in different ethnic groups. For the first time, this study has investigated the association of rs2046210 SNP with breast cancer risk in Iranian Azari-Turkish women in North West Iran. MATERIAL AND METHODS: In this study 192 breast cancer subjects and 186 healthy controls were genotyped using Taqman SNP genotyping assays for different SNP rs2046210 alleles. RESULTS: No significant association between rs2046210 SNP alleles and the risk of breast cancer was detected in Iranian Azari-Turkish women. CONCLUSIONS: The data suggests that rs2046210SNP does not play a role in the aetiology of breast cancer in the Iranian Azari-Turkish population, and it indicates possible genetic differences for breast cancer between different population ancestries. Our result is an important contribution to the literature about genetic susceptibility for breast cancer in Asian populations. Additional studies are required to confirm our findings. PMID- 27688729 TI - Histological characterisation and prognostic evaluation of 62 gastric neuroendocrine carcinomas. AB - AIM OF THE STUDY: To determine the significance of expression of synaptophysin, chromogranin A, and Ki-67 and their association with clinicopathological parameters, and to find out the possible prognostic factors in gastric neuroendocrine carcinoma (G-NEC). MATERIAL AND METHODS: We investigated the immunohistochemical features and prognosis of 62 G-NECs, and evaluated the association among expressions of synaptophysin, chromogranin A, and Ki-67, clinicopathological variables, and outcome. RESULTS: Chromogranin A expression was found more commonly in small-cell NECs (9/9, 100%) than in large-cell NECs (27/53, 51%) (p = 0.008). No statistical significance was found in Ki-67 (p = 0.494) or synaptophysin (p > 0.1) expression between NEC cell types. Correlation analyses revealed that Ki-67 expression was significantly associated with mid third disease of stomach (p = 0.005) and vascular involvement (p = 0.006), and had a trend of significant correlation with tumour relapse (p = 0.078). High expression of chromogranin A was significantly associated with histology of small cell NECs (p = 0.008) and lesser tumour greatest dimension (p = 0.038). The prognostic significance was determined by means of Kaplan-Meier survival estimates and log-rank tests, and as a result, early TNM staging and postoperative chemotherapy were found to be correlated with longer overall survival (p < 0.05). Univariate analysis revealed associations between poor prognosis in NECs and several factors, including high TNM staging (p = 0.048), vascular involvement (p = 0.023), relapse (p = 0.004), and microscopic/macroscopic residual tumour (R1/2, p < 0.001). In a multivariate analysis, relapse was identified as the sole independent prognostic factor. CONCLUSIONS: No significant correlation between survival and expression of synaptophysin, chromogranin A, or Ki-67 has been determined in G-NECs. Our study indicated that early diagnosis, no-residual-tumour resection, and postoperative chemotherapy were possible prognostic factors. PMID- 27688730 TI - Interferon-alpha reduces the gefitinib sensitivity of human non-small cell lung cancer. AB - AIM OF THE STUDY: Many studies have shown that interferon-alpha (IFN-alpha) enhances the antiproliferative effect of gefitinib in some solid tumours. We aimed to determine the effect of combining IFN-alpha with gefitinib in human non small cell lung cancer (NSCLC) cell lines (A549, H1299, HCC827) with different EGFR and K-Ras gene statuses. MATERIAL AND METHODS: An MTT assay was used to assess cell proliferation. Apoptosis was detected by an Annexin V/propidium iodide assay using flow cytometry, and western blotting was used to determine the expression of epidermal growth factor receptor/phosphorylated epidermal growth factor receptor (EGFR/p-EGFR) and signal transducers and activators of transcription 3/phosphorylated signal transducers and activators of transcription 3 (STAT3/p-STAT3). RESULTS: There was an additive interaction when gefitinib was combined with IFN-alpha in all cell lines; however, there was antagonism when gefitinib followed IFN-alpha pretreatment in three cell lines. Notably, IFN-alpha pretreatment significantly reduced the gefitinib sensitivity of HCC827 cells. Surprisingly, while IFN-alpha inhibited STAT3 phosphorylation in cell lines, gefitinib could do so. CONCLUSIONS: The results might confirm the hypothesis that IFN-alpha induces gefitinib sensitivity of NSCLC, and IFN-alpha inhibits phosphorylation of STAT3, which may be dependent on EGFR signal activation playing a role in the reduction of gefitinib sensitivity after IFN-alpha treatment in NSCLC cell lines. PMID- 27688731 TI - Comparison of the hypothetical (57)Co brachytherapy source with the (192)Ir source. AB - AIM OF THE STUDY: The (57)Co radioisotope has recently been proposed as a hypothetical brachytherapy source due to its high specific activity, appropriate half-life (272 days) and medium energy photons (114.17 keV on average). In this study, Task Group No. 43 dosimetric parameters were calculated and reported for a hypothetical (57)Co source. MATERIAL AND METHODS: A hypothetical (57)Co source was simulated in MCNPX, consisting of an active cylinder with 3.5 mm length and 0.6 mm radius encapsulated in a stainless steel capsule. Three photon energies were utilized (136 keV [10.68%], 122 keV [85.60%], 14 keV [9.16%]) for the (57)Co source. Air kerma strength, dose rate constant, radial dose function, anisotropy function, and isodose curves for the source were calculated and compared to the corresponding data for a (192)Ir source. RESULTS: The results are presented as tables and figures. Air kerma strength per 1 mCi activity for the (57)Co source was 0.46 cGyh(-1) cm 2 mCi(-1). The dose rate constant for the (57)Co source was determined to be 1.215 cGyh(-1)U(-1). The radial dose function for the (57)Co source has an increasing trend due to multiple scattering of low energy photons. The anisotropy function for the (57)Co source at various distances from the source is more isotropic than the (192)Ir source. CONCLUSIONS: The (57)Co source has advantages over (192)Ir due to its lower energy photons, longer half-life, higher dose rate constant and more isotropic anisotropic function. However, the (192)Ir source has a higher initial air kerma strength and more uniform radial dose function. These properties make (57)Co a suitable source for use in brachytherapy applications. PMID- 27688732 TI - Male breast cancer: a clinicopathological study of an Egyptian population (Alexandria experience). AB - AIM OF THE STUDY: The purpose of this retrospective study is to evaluate the clinicopathological features and treatment results of male breast cancer presented to our tertiary referral center. MATERIAL AND METHODS: Between January 1998 and December 2005, a total of 39 men with breast cancer treated at Alexandria Main University Hospital and their medical records were reviewed. RESULTS: The median age of patients was 59 years. Only 3 (7.7%) patients had positive family history. All patients presented by breast swellings that were associated with axillary mass in about one third of them. Around 80% had hormone receptor positive (estrogen and/or progesterone receptors). Two third of patients had advanced T-stage (T3 and T4). Left sided breast cancer occurred in 51.3%. Infiltrating ductal carcinoma was the most common type of histology encountered and grade 2 was the predominant grade of tumor. Modified radical mastectomy was the most common (87.2%) type of surgery done followed by chemotherapy for 32 patients and loco-regional radiotherapy for 20 patients. Tamoxifen was administered in 31 patients. Distant relapse occurred in 7 patients (17.9%) and local recurrence occurred in 2 patients (5.1%). The 5-year disease-free survival (DFS) was 82% and the 5-year overall survival (OS) rate was 84%. Only negative axillary lymph node and positive hormone receptor status were significantly associated with favorable DFS and OS. T-stage, grade of tumor and type of chemotherapy given had no statistically significant impact on either DFS or OS. CONCLUSIONS: Male breast cancer is still under-investigated and further researches are warranted. PMID- 27688733 TI - Patterns of care in patients with muscle-invasive bladder cancer - a retrospective cohort study. AB - A potential reason for poor survival among patients with muscle-invasive bladder cancer (MIBC) in Poland is initial disqualification from curative treatment due to advanced stage of the disease or low performance status. The aim of this study was to describe patterns of care in patients with newly diagnosed MIBC. This is a multicentre retrospective cohort study involving 296 consecutive patients with primary histologically diagnosed MIBC. Therapeutic decisions and potentially underlying clinical factors were analysed. Full clinical data was available for 285 patients. One hundred and sixty-four (57.5%) patients were qualified for radical cystectomy (RC), 32 (11.2%) patients for a second step of transurethral resection of the bladder tumour (TURBT) intentionally followed by systemic chemotherapy, four (1.4%) patients after complete TURBT were qualified for adjuvant intravesical chemotherapy only, while the remaining 85 (29.8%) patients were qualified for palliative treatment in the form of chemotherapy and/or radiotherapy and/or best supportive care. Patients disqualified from curative treatment were older (78 vs. 69 years, p < 0.02), had lower BMI values (24.5 vs. 25.7 kg/m(2), p < 0.02), lower haemoglobin concentration (11.6 vs. 12.9 mg/l, p < 0.02), declared lower rate of nicotine abuse (50.5% vs. 72.1%, p < 0.02), and had a shorter time interval between first symptom and diagnosis (30 vs. 60 days, p = 0.02). As the majority of Polish patients with primary MIBC receive curative treatment, the stage of the disease alone seems not to be the leading cause of poor survival. However, appropriateness of qualification for RC and treatment quality needs to be assessed for final conclusion on the factors influencing outcomes of treatment in Poland. PMID- 27688734 TI - Oxidative profile of sickle cell patients in a Cameroonian urban hospital. AB - BACKGROUND: Sickle cell disease (SCD) is a class of hemoglobinopathy resulting from a single mutation in the beta-globin chain inducing the substitution of valine for glutamic acid at the sixth amino acid position which leads to the production of abnormal haemoglobin (haemoglobin S [HbS]). Studies demonstrated the implication of oxidative stress in the development of the sickle cell disease. METHODS: The study aim was to determine the level of oxidative stress markers in a group of sickle cell homozygous patients (SS) in the Yaounde Central Hospital above 15 years of age. Hemolysates obtained from patients were used to investigate some oxidative stress markers including malondialdehyde (MDA), nitric oxide (NO), catalase (CAT), superoxide dismutase (SOD), peroxidase, total antioxidant capacity (TAC) and total protein concentration. RESULTS: Eighty four individuals, 42 males and 42 females participated (50 % each) with an age range of 15 to 55 years. The levels of markers were significantly higher in the healthy AA group than sickle (SS) (p < 0.05), with the exception of MDA which was significantly high in sickle cell (SS) patients than healthy (p = 0.037). With respect to the gender, both healthy and SS females showed a greater Total anti oxidant capacity (65 MUM) compared to the males (55 MUM). CONCLUSION: The increase in the oxidative stress level especially MDA in sickle cell homozygous patients compared to healthy AA individuals confirms that oxidative stress is involved in the pathogenesis of the sickle cell disease. PMID- 27688735 TI - Altering bioelectricity on inhibition of human breast cancer cells. AB - BACKGROUND: Membrane depolarization is associated with breast cancer. Depolarization-activated voltage-gated ion channels are directly implicated in the initiation, proliferation, and metastasis of breast cancer. METHODS: In this study, the role of voltage-gated potassium and calcium ion channel modulation was explored in two different invasive ductal human carcinoma cell lines, MDA-MB-231 (triple-negative) and MCF7 (estrogen-receptor-positive). RESULTS: Resting membrane potential is more depolarized in MCF7 and MDA-MB-231 cells compared to normal human mammary epithelial cells. Increasing extracellular potassium concentration up to 50 mM depolarized membrane potential and greatly increased cell growth. Tetraethylammonium (TEA), a non-specific blocker of voltage-gated potassium channels, stimulated growth of MCF7 cells (control group grew by 201 %, 1 mM TEA group grew 376 %). Depolarization-induced calcium influx was hypothesized as a requirement for growth of human breast cancer. Removing calcium from culture medium stopped growth of MDA and MCF7 cells, leading to cell death after 1 week. Verapamil, a blocker of voltage-gated calcium channels clinically used in treating hypertension and coronary disease, inhibited growth of MDA cells at low concentration (10-20 MUM) by 73 and 92 % after 1 and 2 days, respectively. At high concentration (100 MUM), verapamil killed >90 % of MDA and MCF7 cells after 1 day. Immunoblotting experiments demonstrated that an increased expression of caspase-3, critical in apoptosis signaling, positively correlated with verapamil concentration in MDA cells. In MCF7, caspase-9 expression is increased in response to verapamil. CONCLUSIONS: Our results support our hypotheses that membrane depolarization and depolarization-induced calcium influx stimulate proliferation of human breast cancer cells, independently of cancer subtypes. The underlying mechanism of verapamil-induced cell death involves different caspases in MCF7 and MDA-MB-231. These data suggest that voltage-gated potassium and calcium channels may be putative targets for pharmaceutical remediation in human invasive ductal carcinomas. PMID- 27688736 TI - Long noncoding RNA ANRIL is activated by hypoxia-inducible factor-1alpha and promotes osteosarcoma cell invasion and suppresses cell apoptosis upon hypoxia. AB - BACKGROUND: Osteosarcoma is the most common malignancy of bone. Intratumoral hypoxia occurs in many solid tumors, where it is associated with the development of aggressive phenotype. ANRIL has been shown to be a long noncoding RNA that facilitates the progression of a number of malignancies. Yet, few studies have explored the expression pattern of ANRIL in osteosarcoma and the effect of hypoxia on ANRIL. METHODS: We evaluated the expression levels of ANRIL in osteosarcoma tissues, adjacent normal tissues and cells with quantitative real time polymerase chain reaction. Multiple approaches including luciferase reporter assay with nucleotide substitutions, chromatin immunoprecipitation assay and electrophoretic mobility shift assay were used to confirm the direct binding of HIF-1alpha to the ANRIL promoter region. SiRNA-based knockdown and other molecular biology techniques were employed to measure the effect of HIF-1alpha on the expression of ANRIL. RESULTS: We found that the expression of ANRIL was upregulated in 15 pairs of osteosarcoma compared with adjacent normal tissues. We found that hypoxia is sufficient to upregulate ANRIL expression in osteosarcoma cells (MNNG and U2OS). HIF-1alpha directly binds to the putative hypoxia response element in the upstream region of ANRIL. What's more, siRNA and small molecular inhibitors-mediated HIF-1alpha suppression attenuated ANRIL upregulation under hypoxic conditions. Upon hypoxia, ANRIL promoted cancer cell invasion and suppressed cell apoptosis. CONCLUSION: Taken together, these data suggest that HIF-1alpha may contribute to the upregulation of ANRIL in osteosarcoma under hypoxic conditions. ANRIL is involved in hypoxia-induced aggressive phenotype in osteosarcoma. PMID- 27688737 TI - The effect of inhalation of Citrus sinensis flowers and Mentha spicata leave essential oils on lung function and exercise performance: a quasi-experimental uncontrolled before-and-after study. AB - BACKGROUND: Recently, there has been an increased interest in the effects of essential oils on athletic performances and other physiological effects. This study aimed to assess the effects of Citrus sinensis flower and Mentha spicata leaves essential oils inhalation in two different groups of athlete male students on their exercise performance and lung function. METHODS: Twenty physical education students volunteered to participate in the study. The subjects were randomly assigned into two groups: Mentha spicata and Citrus sinensis (ten participants each). One group was nebulized by Citrus sinensis flower oil and the other by Mentha spicata leaves oil in a concentration of (0.02 ml/kg of body mass) which was mixed with 2 ml of normal saline for 5 min before a 1500 m running tests. Lung function tests were measured using a spirometer for each student pre and post nebulization giving the same running distance pre and post oils inhalation. RESULTS: A lung function tests showed an improvement on the lung status for the students after inhaling of the oils. Interestingly, there was a significant increase in Forced Expiratory Volume in the first second and Forced Vital Capacity after inhalation for the both oils. Moreover significant reductions in the means of the running time were observed among these two groups. The normal spirometry results were 50 %, while after inhalation with M. spicata oil the ratio were 60 %. CONCLUSION: Our findings support the effectiveness of M. spicata and C. sinensis essential oils on the exercise performance and respiratory function parameters. However, our conclusion and generalisability of our results should be interpreted with caution due to small sample size and lack of control groups, randomization or masking. We recommend further investigations to explain the mechanism of actions for these two essential oils on exercise performance and respiratory parameters. TRIAL REGISTRATION: ISRCTN10133422, Registered: May 3, 2016. PMID- 27688739 TI - Prevalence and Predictors of Video Game Addiction: A Study Based on a National Representative Sample of Gamers. AB - Video gaming has become a popular leisure activity in many parts of the world, and an increasing number of empirical studies examine the small minority that appears to develop problems as a result of excessive gaming. This study investigated prevalence rates and predictors of video game addiction in a sample of gamers, randomly selected from the National Population Registry of Norway (N = 3389). Results showed there were 1.4 % addicted gamers, 7.3 % problem gamers, 3.9 % engaged gamers, and 87.4 % normal gamers. Gender (being male) and age group (being young) were positively associated with addicted-, problem-, and engaged gamers. Place of birth (Africa, Asia, South- and Middle America) were positively associated with addicted- and problem gamers. Video game addiction was negatively associated with conscientiousness and positively associated with neuroticism. Poor psychosomatic health was positively associated with problem- and engaged gaming. These factors provide insight into the field of video game addiction, and may help to provide guidance as to how individuals that are at risk of becoming addicted gamers can be identified. PMID- 27688738 TI - Detection of IL-17 and IL-23 in Plasma Samples of Children with Autism. AB - Interleukin-23 (IL-23) is a survival factor for a newly described population of T lymphocytes, namely Th-17 cells, that secrete IL-17, tumor necrosis factor- alpha (TNFalpha) and IL-6. It has been shown that Th-17 cells are a pathogenic T cell subset involved in autoimmune and chronic inflammatory diseases. Based on the increasing evidence of immune dysfunction in autism, including possible autoimmune and inflammatory processes, we hypothesized that Th-17 cells, a T cell lineage that has not been previously examined in this disorder, may be altered in autism. To assess the potential role, if any, of Th-17 cells in autism, we analyzed plasma samples obtained from children ranging in age from 2-5 years with a diagnosis of autism and age-matched typically developing controls for the presence of IL-17 and IL-23 cytokines. Plasma samples from 40 children with autism including 20 children with a regressive form of autism, 20 with early onset and no regression and 20 typically developing age-matched control children were analyzed for IL-17 and IL-23, under the hypothesis that altered number and function of Th-17 cells would directly correlate with altered levels of IL-17 and IL-23 in the plasma. In this study, we were able to demonstrate that IL-23 cytokine levels were significantly different in children with autism compared with age-matched controls, a finding primarily driven by children with early onset autism. In contrast, there were no statistical differences in IL-17 levels autism compared with age-matched typically developing controls. This is the first study to report altered IL-23 production in autism. The decreased plasma IL-23 production observed in children with autism warrants further research as to its affect on the generation and survival of Th-17 cells, a subset important in neuroinflammatory conditions that may include autism. PMID- 27688740 TI - The Mechanisms of Mindfulness in the Treatment of Mental Illness and Addiction. AB - Consistent with its growing popularity amongst the general public and medical community, throughout recent decades there have been increasing attempts to understand the mechanisms that underlie therapeutic improvement in individuals receiving mindfulness training. The current paper draws upon findings from various remits of scientific enquiry and summarises key evidence-based mechanisms of mindfulness that have been proposed in the academic literature to date. Empirical findings indicate that mindfulness targets biological, psychological, social, and spiritual psychopathology determinants. Furthermore, the mechanistic pathways exploited by mindfulness are likely to vary according to factors such as (i) the type of mindfulness-based intervention that is administered (e.g., first- or second-generation mindfulness-based interventions), (ii) the specific clinical disorder that is being targeted, (iii) the educational, social, and spiritual history of the participant, and (iv) the extent to which the mindfulness instructor truly embodies the principles of mindful living. It is hoped that the mechanisms of mindfulness discussed in this paper will contribute to the formulation of a more complete picture that can be tested and expanded upon during future scientific enquiry.

AB - Accurate and up-to-date information on the spatial distribution of paddy rice fields is necessary for the studies of trace gas emissions, water source management, and food security. The phenology-based paddy rice mapping algorithm, which identifies the unique flooding stage of paddy rice, has been widely used. However, identification and mapping of paddy rice in rice-wetland coexistent areas is still a challenging task. In this study, we found that the flooding/transplanting periods of paddy rice and natural wetlands were different. The natural wetlands flood earlier and have a shorter duration than paddy rice in the Panjin Plain, a temperate region in China. We used this asynchronous flooding stage to extract the paddy rice planting area from the rice-wetland coexistent area. MODIS Land Surface Temperature (LST) data was used to derive the temperature-defined plant growing season. Landsat 8 OLI imagery was used to detect the flooding signal and then paddy rice was extracted using the difference in flooding stages between paddy rice and natural wetlands. The resultant paddy rice map was evaluated with in-situ ground-truth data and Google Earth images. The estimated overall accuracy and Kappa coefficient were 95% and 0.90, respectively. The spatial pattern of OLI-derived paddy rice map agrees well with the paddy rice layer from the National Land Cover Dataset from 2010 (NLCD-2010). The differences between RiceLandsat and RiceNLCD are in the range of +/-20% for most 1-km grid cell. The results of this study demonstrate the potential of the phenology-based paddy rice mapping algorithm, via integrating MODIS and Landsat 8 OLI images, to map paddy rice fields in complex landscapes of paddy rice and natural wetland in the temperate region. PMID- 27688741 TI - Increased sialylation of site specific O-glycoforms of hemopexin in liver disease. AB - BACKGROUND: Non-invasive monitoring of liver disease remains an important health issue. Liver secreted glycoproteins reflect pathophysiological states of the organ and represent a rational target for serologic monitoring. In this study, we describe sialylated O-glycoforms of liver-secreted hemopexin (HPX) and quantify them as a ratio of disialylated to monosialylated form (S-HPX). METHODS: We measured S-HPX in serum of participants of the HALT-C trial using a LC-MS/MS-MRM assay. RESULTS: Repeated measurements of S-HPX in the samples of 23 disease-free controls, collected at four different time points, show that the ratio remains stable in the healthy controls but increases with the progression of liver disease. The results of measurement of S-HPX in serum of participants of the HALT C trial show that it increased significantly (Kruskal-Wallis test, p < 0.01) in liver disease as the stage of fibrosis progressed in liver biopsies. We observed a 1.7-fold increase in fibrosis defined as Ishak score 3-4 (24.9 + 14.2, n = 22) and 4.7-fold increase in cirrhosis defined as Ishak score 5-6 (68.6 + 38.5; n = 24) compared to disease-free controls (14.7 + 6.7, n = 23). S-HPX is correlated with AFP, bilirubin, INR, ALT, and AST while inversely correlated with platelet count and albumin. In an independent verification set of samples, S-HPX separated the Ishak 5-6 (n = 15) from the Ishak 3-4 (n = 15) participants with AuROC 0.84; at the same time, the Ishak 3-4 group was separated from disease-free controls (n = 15) with AuROC 0.82. CONCLUSION: S-HPX, a measure of sialylated O-glycoforms of hemopexin, progressively increases in fibrotic and cirrhotic patient of HCV etiology and can be quantified by an LC-MS/MS-MRM assay in unfractionated serum of patients. Quantification of sialylated O-glycoforms of this liver secreted glycoprotein represents a novel measure of the stage of liver disease that could have a role in monitoring the progression of liver pathology. PMID- 27688744 TI - Detecting Visually Observable Disease Symptoms from Faces. AB - Recent years have witnessed an increasing interest in the application of machine learning to clinical informatics and healthcare systems. A significant amount of research has been done on healthcare systems based on supervised learning. In this study, we present a generalized solution to detect visually observable symptoms on faces using semi-supervised anomaly detection combined with machine vision algorithms. We rely on the disease-related statistical facts to detect abnormalities and classify them into multiple categories to narrow down the possible medical reasons of detecting. Our method is in contrast with most existing approaches, which are limited by the availability of labeled training data required for supervised learning, and therefore offers the major advantage of flagging any unusual and visually observable symptoms. PMID- 27688745 TI - Retinal Fundus Image Enhancement Using the Normalized Convolution and Noise Removing. AB - Retinal fundus image plays an important role in the diagnosis of retinal related diseases. The detailed information of the retinal fundus image such as small vessels, microaneurysms, and exudates may be in low contrast, and retinal image enhancement usually gives help to analyze diseases related to retinal fundus image. Current image enhancement methods may lead to artificial boundaries, abrupt changes in color levels, and the loss of image detail. In order to avoid these side effects, a new retinal fundus image enhancement method is proposed. First, the original retinal fundus image was processed by the normalized convolution algorithm with a domain transform to obtain an image with the basic information of the background. Then, the image with the basic information of the background was fused with the original retinal fundus image to obtain an enhanced fundus image. Lastly, the fused image was denoised by a two-stage denoising method including the fourth order PDEs and the relaxed median filter. The retinal image databases, including the DRIVE database, the STARE database, and the DIARETDB1 database, were used to evaluate image enhancement effects. The results show that the method can enhance the retinal fundus image prominently. And, different from some other fundus image enhancement methods, the proposed method can directly enhance color images. PMID- 27688743 TI - An Automated Approach for Localizing Retinal Blood Vessels in Confocal Scanning Laser Ophthalmoscopy Fundus Images. AB - In this work, we present a rules-based method for localizing retinal blood vessels in confocal scanning laser ophthalmoscopy (cSLO) images and evaluate its feasibility. A total of 31 healthy participants (17 female; mean age: 64.0 +/- 8.2 years) were studied using manual and automatic segmentation. High-resolution peripapillary scan acquisition cSLO images were acquired. The automated segmentation method consisted of image pre-processing for gray-level homogenization and blood vessel enhancement (morphological opening operation, Gaussian filter, morphological Top-Hat transformation), binary thresholding (entropy-based thresholding operation), and removal of falsely detected isolated vessel pixels. The proposed algorithm was first tested on the publically available dataset DRIVE, which contains color fundus photographs, and compared to performance results from the literature. Good results were obtained. Monochromatic cSLO images segmented using the proposed method were compared to those manually segmented by two independent observers. For the algorithm, a sensitivity of 0.7542, specificity of 0.8607, and accuracy of 0.8508 were obtained. For the two independent observers, a sensitivity of 0.6579, specificity of 0.9699, and accuracy of 0.9401 were obtained. The results demonstrate that it is possible to localize vessels in monochromatic cSLO images of the retina using a rules-based approach. The performance results are inferior to those obtained using fundus photography, which could be due to the nature of the technology. PMID- 27688747 TI - High-Resolution Cortical Dipole Imaging Using Spatial Inverse Filter Based on Filtering Property. AB - Cortical dipole imaging has been developed to visualize brain electrical activity in high spatial resolution. It is necessary to solve an inverse problem to estimate the cortical dipole distribution from the scalp potentials. In the present study, the accuracy of cortical dipole imaging was improved by focusing on filtering property of the spatial inverse filter. We proposed an inverse filter that optimizes filtering property using a sigmoid function. The ability of the proposed method was compared with the traditional inverse techniques, such as Tikhonov regularization, truncated singular value decomposition (TSVD), and truncated total least squares (TTLS), in a computer simulation. The proposed method was applied to human experimental data of visual evoked potentials. As a result, the estimation accuracy was improved and the localized dipole distribution was obtained with less noise. PMID- 27688746 TI - Discovering Patterns in Brain Signals Using Decision Trees. AB - Even with emerging technologies, such as Brain-Computer Interfaces (BCI) systems, understanding how our brains work is a very difficult challenge. So we propose to use a data mining technique to help us in this task. As a case of study, we analyzed the brain's behaviour of blind people and sighted people in a spatial activity. There is a common belief that blind people compensate their lack of vision using the other senses. If an object is given to sighted people and we asked them to identify this object, probably the sense of vision will be the most determinant one. If the same experiment was repeated with blind people, they will have to use other senses to identify the object. In this work, we propose a methodology that uses decision trees (DT) to investigate the difference of how the brains of blind people and people with vision react against a spatial problem. We choose the DT algorithm because it can discover patterns in the brain signal, and its presentation is human interpretable. Our results show that using DT to analyze brain signals can help us to understand the brain's behaviour. PMID- 27688748 TI - Fuzzy Logic Based Control for Autonomous Mobile Robot Navigation. AB - This paper describes the design and the implementation of a trajectory tracking controller using fuzzy logic for mobile robot to navigate in indoor environments. Most of the previous works used two independent controllers for navigation and avoiding obstacles. The main contribution of the paper can be summarized in the fact that we use only one fuzzy controller for navigation and obstacle avoidance. The used mobile robot is equipped with DC motor, nine infrared range (IR) sensors to measure the distance to obstacles, and two optical encoders to provide the actual position and speeds. To evaluate the performances of the intelligent navigation algorithms, different trajectories are used and simulated using MATLAB software and SIMIAM navigation platform. Simulation results show the performances of the intelligent navigation algorithms in terms of simulation times and travelled path. PMID- 27688749 TI - Reduced Representation Bisulfite Sequencing Determination of Distinctive DNA Hypermethylated Genes in the Progression to Colon Cancer in African Americans. AB - Background and Aims. Many studies have focused on the determination of methylated targets in colorectal cancer. However, few analyzed the progressive methylation in the sequence from normal to adenoma and ultimately to malignant tumors. This is of utmost importance especially in populations such as African Americans who generally display aggressive tumors at diagnosis and for whom markers of early neoplasia are needed. We aimed to determine methylated targets in the path to colon cancer in African American patients using Reduced Representation Bisulfite Sequencing (RRBS). Methods. Genomic DNA was isolated from fresh frozen tissues of patients with different colon lesions: normal, a tubular adenoma, a tubulovillous adenoma, and five cancers. RRBS was performed on these DNA samples to identify hypermethylation. Alignment, mapping, and confirmed CpG methylation analyses were performed. Preferential hypermethylated pathways were determined using Ingenuity Pathway Analysis (IPA). Results. We identified hypermethylated CpG sites in the following genes: L3MBTL1, NKX6-2, PREX1, TRAF7, PRDM14, and NEFM with the number of CpG sites being 14, 17, 10, 16, 6, and 6, respectively, after pairwise analysis of normal versus adenoma, adenoma versus cancer, and normal versus cancer. IPA mapped the above-mentioned hypermethylated genes to the Wnt/beta catenin, PI3k/AKT, VEGF, and JAK/STAT3 signaling pathways. Conclusion. This work provides insight into novel differential CpGs hypermethylation sites in colorectal carcinogenesis. Functional analysis of the novel gene targets is needed to confirm their roles in their associated carcinogenic pathways. PMID- 27688751 TI - Novel Bioceramic Urethral Bulking Agents Elicit Improved Host Tissue Responses in a Rat Model. AB - Objectives. To test the physical properties and host response to the bioceramic particles, silica-calcium phosphate (SCPC10) and Cristobalite, in a rat animal model and compare their biocompatibility to the current clinically utilized urethral bulking materials. Material and Methods. The novel bulking materials, SCPC10 and Cristobalite, were suspended in hyaluronic acid sodium salt and injected into the mid urethra of a rat. Additional animals were injected with bulking materials currently in clinical use. Physiological response was assessed using voiding trials, and host tissue response was evaluated using hard tissue histology and immunohistochemical analysis. Distant organs were evaluated for the presence of particles or their components. Results. Histological analysis of the urethral tissue five months after injection showed that both SCPC10 and Cristobalite induced a more robust fibroblastic and histiocytic reaction, promoting integration and encapsulation of the particle aggregates, leading to a larger bulking effect. Concentrations of Ca, Na, Si, and P ions in the experimental groups were comparable to control animals. Conclusions. This side-by side examination of urethral bulking agents using a rat animal model and hard tissue histology techniques compared two newly developed bioactive ceramic particles to three of the currently used bulking agents. The local host tissue response and bulking effects of bioceramic particles were superior while also possessing a comparable safety profile. PMID- 27688752 TI - The Self-Perception and Usage of Medical Apps amongst Medical Students in the United States: A Cross-Sectional Survey. AB - Background. Mobile medical software applications (apps) are used for clinical decision-making at the point of care. Objectives. To determine (1) the usage, reliability, and popularity of mobile medical apps and (2) medical students' perceptions of app usage effect on the quality of patient-provider interaction in healthcare settings. Methods. An anonymous web-based survey was distributed to medical students. Frequency of use, type of app used, and perceptions of reliability were assessed via univariate analysis. Results. Seven hundred thirty one medical students responded, equating to a response rate of 29%. The majority (90%) of participants thought that medical apps enhance clinical knowledge, and 61% said that medical apps are as reliable as textbooks. While students thought that medical apps save time, improve the care of their patients, and improve diagnostic accuracy, 53% of participants believed that mobile device use in front of colleagues and patients makes one appear less competent. Conclusion. While medical students believe in the utility and reliability of medical apps, they were hesitant to use them out of fear of appearing less engaged. Higher levels of training correlated with a greater degree of comfort when using medical apps in front of patients. PMID- 27688750 TI - Nutrition and Helicobacter pylori: Host Diet and Nutritional Immunity Influence Bacterial Virulence and Disease Outcome. AB - Helicobacter pylori colonizes the stomachs of greater than 50% of the world's human population making it arguably one of the most successful bacterial pathogens. Chronic H. pylori colonization results in gastritis in nearly all patients; however in a subset of people, persistent infection with H. pylori is associated with an increased risk for more severe disease outcomes including B cell lymphoma of mucosal-associated lymphoid tissue (MALT lymphoma) and invasive adenocarcinoma. Research aimed at elucidating determinants that mediate disease progression has revealed genetic differences in both humans and H. pylori which increase the risk for developing gastric cancer. Furthermore, host diet and nutrition status have been shown to influence H. pylori-associated disease outcomes. In this review we will discuss how H. pylori is able to create a replicative niche within the hostile host environment by subverting and modifying the host-generated immune response as well as successfully competing for limited nutrients such as transition metals by deploying an arsenal of metal acquisition proteins and virulence factors. Lastly, we will discuss how micronutrient availability or alterations in the gastric microbiome may exacerbate negative disease outcomes associated with H. pylori colonization. PMID- 27688753 TI - Systematic Bioinformatic Approach for Prediction of Linear B-Cell Epitopes on Dengue E and prM Protein. AB - B-cell epitopes on the envelope (E) and premembrane (prM) proteins of dengue virus (DENV) were predicted using bioinformatics tools, BepiPred, Ellipro, and SVMTriP. Predicted epitopes, 32 and 17 for E and prM proteins, respectively, were then characterized for their level of conservations. The epitopes, EP4/E (48-55), epitope number 4 of E protein at amino acids 48-55, EP9/E (165-182), EP11/E (218 233), EP20/E (322-349), EP21/E (326-353), EP23/E (356-365), and EP25/E (380-386), showed a high intraserotype conservancy with very low pan-serotype conservancy, demonstrating a potential target as serotype specific diagnostic markers. EP3 (30 41) located in domain-I and EP26/E (393-409), EP27/E (416-435), EP28/E (417-430) located in the stem region of E protein, and EP8/prM (93-112) from the prM protein have a pan-serotype conservancy higher than 70%. These epitopes indicate a potential use as universal vaccine candidates, subjected to verification of their potential in viral neutralization. EP2/E (16-21), EP5/E (62-123), EP6/E (63 89), EP19/E (310-329), and EP24/E (371-402), which have more than 50% pan serotype conservancies, were found on E protein regions that are important in host cell attachment. Previous studies further show evidence for some of these epitopes to generate cross-reactive neutralizing antibodies, indicating their importance in antiviral strategies for DENV. This study suggests that bioinformatic approaches are attractive first line of screening for identification of linear B-cell epitopes. PMID- 27688754 TI - Inositols in the Treatment of Insulin-Mediated Diseases. AB - A growing body of research is currently focused on the role of inositol isomers and in particular myo-inositol (MYO-INS) and D-chiroinositol (DCI) in the treatment of insulin resistance states. Both isomers have been shown to exert insulin-mimetic action and to lower postprandial glucose. Further, insulin resistance-related diseases were associated to derangements in inositol metabolism. Thus, the aim of this review is to provide current evidence on the potential benefits of inositol isomers (MYO-INS and DCI) in the treatment of disease associated to insulin resistance such as polycystic ovary syndrome (PCOS), gestational diabetes, and metabolic syndrome. Finally, molecular insights into inositol insulin-sensitizing effects will be covered focusing on the possible role of inositol glycans as insulin second messengers. PMID- 27688755 TI - Mammalian Period represses and de-represses transcription by displacing CLOCK BMAL1 from promoters in a Cryptochrome-dependent manner. AB - The mammalian circadian clock is based on a transcription-translation feedback loop (TTFL) consolidated by secondary loops. In the primary TTFL, the circadian locomotor output cycles kaput (CLOCK)-brain and muscle Arnt-like protein-1 (BMAL1) heterodimer acts as the transcriptional activator, and Cryptochrome (CRY) and Period (PER) proteins function as repressors. PER represses by displacing CLOCK-BMAL1 from promoters in a CRY-dependent manner. Interestingly, genes with complex promoters may either be repressed or de-repressed by PER, depending on the particular promoter regulatory elements. Here, using mouse cell lines with defined knockout mutations in clock genes, RNA-seq, ChIP-seq, and reporter gene assays coupled with measurements of DNA-protein interactions in nuclear extracts, we elucidate the dual functions of PER as repressor and de-repressor in a context dependent manner. PMID- 27688756 TI - Blue protein with red fluorescence. AB - The walleye (Sander vitreus) is a golden yellow fish that inhabits the Northern American lakes. The recent sightings of the blue walleye and the correlation of its sighting to possible increased UV radiation have been proposed earlier. The underlying molecular basis of its adaptation to increased UV radiation is the presence of a protein (Sandercyanin)-ligand complex in the mucus of walleyes. Degradation of heme by UV radiation results in the formation of Biliverdin IXalpha (BLA), the chromophore bound to Sandercyanin. We show that Sandercyanin is a monomeric protein that forms stable homotetramers on addition of BLA to the protein. A structure of the Sandercyanin-BLA complex, purified from the fish mucus, reveals a glycosylated protein with a lipocalin fold. This protein-ligand complex absorbs light in the UV region (lambdamax of 375 nm) and upon excitation at this wavelength emits in the red region (lambdamax of 675 nm). Unlike all other known biliverdin-bound fluorescent proteins, the chromophore is noncovalently bound to the protein. We provide here a molecular rationale for the observed spectral properties of Sandercyanin. PMID- 27688757 TI - Cisplatin DNA damage and repair maps of the human genome at single-nucleotide resolution. AB - Cisplatin is a major anticancer drug that kills cancer cells by damaging their DNA. Cancer cells cope with the drug by removal of the damages with nucleotide excision repair. We have developed methods to measure cisplatin adduct formation and its repair at single-nucleotide resolution. "Damage-seq" relies on the replication-blocking properties of the bulky base lesions to precisely map their location. "XR-seq" independently maps the removal of these damages by capturing and sequencing the excised oligomer released during repair. The damage and repair maps we generated reveal that damage distribution is essentially uniform and is dictated mostly by the underlying sequence. In contrast, cisplatin repair is heterogeneous in the genome and is affected by multiple factors including transcription and chromatin states. Thus, the overall effect of damages in the genome is primarily driven not by damage formation but by the repair efficiency. The combination of the Damage-seq and XR-seq methods has the potential for developing novel cancer therapeutic strategies. PMID- 27688758 TI - Transferable model for chromosome architecture. AB - In vivo, the human genome folds into a characteristic ensemble of 3D structures. The mechanism driving the folding process remains unknown. We report a theoretical model for chromatin (Minimal Chromatin Model) that explains the folding of interphase chromosomes and generates chromosome conformations consistent with experimental data. The energy landscape of the model was derived by using the maximum entropy principle and relies on two experimentally derived inputs: a classification of loci into chromatin types and a catalog of the positions of chromatin loops. First, we trained our energy function using the Hi C contact map of chromosome 10 from human GM12878 lymphoblastoid cells. Then, we used the model to perform molecular dynamics simulations producing an ensemble of 3D structures for all GM12878 autosomes. Finally, we used these 3D structures to generate contact maps. We found that simulated contact maps closely agree with experimental results for all GM12878 autosomes. The ensemble of structures resulting from these simulations exhibited unknotted chromosomes, phase separation of chromatin types, and a tendency for open chromatin to lie at the periphery of chromosome territories. PMID- 27688760 TI - Antimicrobial lipopeptide tridecaptin A1 selectively binds to Gram-negative lipid II. AB - Tridecaptin A1 (TriA1) is a nonribosomal lipopeptide with selective antimicrobial activity against Gram-negative bacteria. Here we show that TriA1 exerts its bactericidal effect by binding to the bacterial cell-wall precursor lipid II on the inner membrane, disrupting the proton motive force. Biochemical and biophysical assays show that binding to the Gram-negative variant of lipid II is required for membrane disruption and that only the proton gradient is dispersed. The NMR solution structure of TriA1 in dodecylphosphocholine micelles with lipid II has been determined, and molecular modeling was used to provide a structural model of the TriA1-lipid II complex. These results suggest that TriA1 kills Gram negative bacteria by a mechanism of action using a lipid-II-binding motif. PMID- 27688759 TI - Oligodendrocytes contribute to motor neuron death in ALS via SOD1-dependent mechanism. AB - Oligodendrocytes have recently been implicated in the pathophysiology of amyotrophic lateral sclerosis (ALS). Here we show that, in vitro, mutant superoxide dismutase 1 (SOD1) mouse oligodendrocytes induce WT motor neuron (MN) hyperexcitability and death. Moreover, we efficiently derived human oligodendrocytes from a large number of controls and patients with sporadic and familial ALS, using two different reprogramming methods. All ALS oligodendrocyte lines induced MN death through conditioned medium (CM) and in coculture. CM mediated MN death was associated with decreased lactate production and release, whereas toxicity in coculture was lactate-independent, demonstrating that MN survival is mediated not only by soluble factors. Remarkably, human SOD1 shRNA treatment resulted in MN rescue in both mouse and human cultures when knockdown was achieved in progenitor cells, whereas it was ineffective in differentiated oligodendrocytes. In fact, early SOD1 knockdown rescued lactate impairment and cell toxicity in all lines tested, with the exclusion of samples carrying chromosome 9 ORF 72 (C9orf72) repeat expansions. These did not respond to SOD1 knockdown nor did they show lactate release impairment. Our data indicate that SOD1 is directly or indirectly involved in ALS oligodendrocyte pathology and suggest that in this cell type, some damage might be irreversible. In addition, we demonstrate that patients with C9ORF72 represent an independent patient group that might not respond to the same treatment. PMID- 27688761 TI - Transparent antifouling material for improved operative field visibility in endoscopy. AB - Camera-guided instruments, such as endoscopes, have become an essential component of contemporary medicine. The 15-20 million endoscopies performed every year in the United States alone demonstrate the tremendous impact of this technology. However, doctors heavily rely on the visual feedback provided by the endoscope camera, which is routinely compromised when body fluids and fogging occlude the lens, requiring lengthy cleaning procedures that include irrigation, tissue rubbing, suction, and even temporary removal of the endoscope for external cleaning. Bronchoscopies are especially affected because they are performed on delicate tissue, in high-humidity environments with exposure to extremely adhesive biological fluids such as mucus and blood. Here, we present a repellent, liquid-infused coating on an endoscope lens capable of preventing vision loss after repeated submersions in blood and mucus. The material properties of the coating, including conformability, mechanical adhesion, transparency, oil type, and biocompatibility, were optimized in comprehensive in vitro and ex vivo studies. Extensive bronchoscopy procedures performed in vivo on porcine lungs showed significantly reduced fouling, resulting in either unnecessary or ~10-15 times shorter and less intensive lens clearing procedures compared with an untreated endoscope. We believe that the material developed in this study opens up opportunities in the design of next-generation endoscopes that will improve visual field, display unprecedented antibacterial and antifouling properties, reduce the duration of the procedure, and enable visualization of currently unreachable parts of the body, thus offering enormous potential for disease diagnosis and treatment. PMID- 27688763 TI - An advanced modeling study on the impacts and atmospheric implications of multiphase dimethyl sulfide chemistry. AB - Oceans dominate emissions of dimethyl sulfide (DMS), the major natural sulfur source. DMS is important for the formation of non-sea salt sulfate (nss-SO42-) aerosols and secondary particulate matter over oceans and thus, significantly influence global climate. The mechanism of DMS oxidation has accordingly been investigated in several different model studies in the past. However, these studies had restricted oxidation mechanisms that mostly underrepresented important aqueous-phase chemical processes. These neglected but highly effective processes strongly impact direct product yields of DMS oxidation, thereby affecting the climatic influence of aerosols. To address these shortfalls, an extensive multiphase DMS chemistry mechanism, the Chemical Aqueous Phase Radical Mechanism DMS Module 1.0, was developed and used in detailed model investigations of multiphase DMS chemistry in the marine boundary layer. The performed model studies confirmed the importance of aqueous-phase chemistry for the fate of DMS and its oxidation products. Aqueous-phase processes significantly reduce the yield of sulfur dioxide and increase that of methyl sulfonic acid (MSA), which is needed to close the gap between modeled and measured MSA concentrations. Finally, the simulations imply that multiphase DMS oxidation produces equal amounts of MSA and sulfate, a result that has significant implications for nss-SO42- aerosol formation, cloud condensation nuclei concentration, and cloud albedo over oceans. Our findings show the deficiencies of parameterizations currently used in higher scale models, which only treat gas-phase chemistry. Overall, this study shows that treatment of DMS chemistry in both gas and aqueous phases is essential to improve the accuracy of model predictions. PMID- 27688762 TI - Noninvasive chromosome screening of human embryos by genome sequencing of embryo culture medium for in vitro fertilization. AB - Preimplantation genetic screening (PGS) is widely used to select in vitro fertilized embryos free of chromosomal abnormalities and to improve the clinical outcome of in vitro fertilization (IVF). A disadvantage of PGS is that it requires biopsy of the preimplantation human embryo, which can limit the clinical applicability of PGS due to the invasiveness and complexity of the process. Here, we present and validate a noninvasive chromosome screening (NICS) method based on sequencing the genomic DNA secreted into the culture medium from the human blastocyst. By using multiple annealing and looping-based amplification cycles (MALBAC) for whole-genome amplification (WGA), we performed next-generation sequencing (NGS) on the spent culture medium used to culture human blastocysts (n = 42) and obtained the ploidy information of all 24 chromosomes. We validated these results by comparing each with their corresponding whole donated embryo and obtained a high correlation for identification of chromosomal abnormalities (sensitivity, 0.882, and specificity, 0.840). With this validated NICS method, we performed chromosome screening on IVF embryos from seven couples with balanced translocation, azoospermia, or recurrent pregnancy loss. Six of them achieved successful clinical pregnancies, and five have already achieved healthy live births thus far. The NICS method avoids the need for embryo biopsy and therefore substantially increases the safety of its use. The method has the potential of much wider chromosome screening applicability in clinical IVF, due to its high accuracy and noninvasiveness. PMID- 27688764 TI - Rawlsian maximin rule operates as a common cognitive anchor in distributive justice and risky decisions. AB - Distributive justice concerns the moral principles by which we seek to allocate resources fairly among diverse members of a society. Although the concept of fair allocation is one of the fundamental building blocks for societies, there is no clear consensus on how to achieve "socially just" allocations. Here, we examine neurocognitive commonalities of distributive judgments and risky decisions. We explore the hypothesis that people's allocation decisions for others are closely related to economic decisions for oneself at behavioral, cognitive, and neural levels, via a concern about the minimum, worst-off position. In a series of experiments using attention-monitoring and brain-imaging techniques, we investigated this "maximin" concern (maximizing the minimum possible payoff) via responses in two seemingly disparate tasks: third-party distribution of rewards for others, and choosing gambles for self. The experiments revealed three robust results: (i) participants' distributive choices closely matched their risk preferences-"Rawlsians," who maximized the worst-off position in distributions for others, avoided riskier gambles for themselves, whereas "utilitarians," who favored the largest-total distributions, preferred riskier but more profitable gambles; (ii) across such individual choice preferences, however, participants generally showed the greatest spontaneous attention to information about the worst possible outcomes in both tasks; and (iii) this robust concern about the minimum outcomes was correlated with activation of the right temporoparietal junction (RTPJ), the region associated with perspective taking. The results provide convergent evidence that social distribution for others is psychologically linked to risky decision making for self, drawing on common cognitive-neural processes with spontaneous perspective taking of the worst-off position. PMID- 27688765 TI - Surfactant adsorption kinetics in microfluidics. AB - Emulsions are metastable dispersions. Their lifetimes are directly related to the dynamics of surfactants. We design a microfluidic method to measure the kinetics of adsorption of surfactants to the droplet interface, a key process involved in foaming, emulsification, and droplet coarsening. The method is based on the pH decay in the droplet as a direct measurement of the adsorption of a carboxylic acid surfactant to the interface. From the kinetic measurement of the bulk equilibration of the pH, we fully determine the adsorption process of the surfactant. The small droplet size and the convection during the droplet flow ensure that the transport of surfactant through the bulk is not limiting the kinetics of adsorption. To validate our measurements, we show that the adsorption process determines the timescale required to stabilize droplets against coalescence, and we show that the interface should be covered at more than [Formula: see text] to prevent coalescence. We therefore quantitatively link the process of adsorption/desorption, the stabilization of emulsions, and the kinetics of solute partitioning-here through ion exchange-unraveling the timescales governing these processes. Our method can be further generalized to other surfactants, including nonionic surfactants, by making use of fluorophore surfactant interactions. PMID- 27688766 TI - Catalysis at the nanoscale may change selectivity. AB - Among the many virtues ascribed to catalytic nanoparticles, the prospect that the passage from the macro- to the nanoscale may change product selectivity attracts increasing attention. To date, why such effects may exist lacks explanation. Guided by recent experimental reports, we propose that the effects may result from the coupling between the chemical steps in which the reactant, intermediates, and products are involved and transport of these species toward the catalytic surface. Considering as a thought experiment the competitive formation of hydrogen and formate upon reduction of hydrogenocarbonate ions on metals like palladium or platinum, a model is developed that allows one to identify the governing parameters and predict the effect of nanoscaling on selectivity. The model leads to a master equation relating product selectivity and thickness of the diffusion layer. The latter parameter varies considerably upon passing from the macro- to the nanoscale, thus predicting considerable variations of product selectivity. These are subtle effects in the sense that the same mechanism might exhibit a reverse variation of the selectivity if the set of parameter values were different. An expression is given that allows one to predict the direction of the effect. There has been a tendency to assign the catalytic effects of nanoscaling to chemical reactivity changes of the active surface. Such factors might be important in some circumstances. We, however, insist on the likely role of short-distance transport on product selectivity, which could have been thought, at first sight, as the exclusive domain of chemical factors. PMID- 27688767 TI - Targeted imaging of urothelium carcinoma in human bladders by an ICG pHLIP peptide ex vivo. AB - Bladder cancer is the fifth most common in incidence and one of the most expensive cancers to treat. Early detection greatly improves the chances of survival and bladder preservation. The pH low insertion peptide (pHLIP) conjugated with a near-infrared fluorescent dye [indocyanine green (ICG)] targets low extracellular pH, allowing visualization of malignant lesions in human bladder carcinoma ex vivo. Cystectomy specimens obtained after radical surgery were immediately irrigated with nonbuffered saline and instilled with a solution of the ICG pHLIP construct, incubated, and rinsed. Bladders were subsequently opened and imaged, the fluorescent spots were marked, and a standard pathological analysis was carried out to establish the correlation between ICG pHLIP imaging and white light pathological assessment. Accurate targeting of bladder lesions was achieved with a sensitivity of 97%. Specificity is 100%, but reduced to 80% if targeting of necrotic tissue from previous transurethral resections or chemotherapy are considered as false positives. The ICG pHLIP imaging agent marked high-grade urothelial carcinomas, both muscle invasive and nonmuscle invasive. Carcinoma in situ was accurately diagnosed in 11 cases, whereas only four cases were seen using white light, so imaging with the ICG pHLIP peptide offers improved early diagnosis of bladder cancers and may also enable new treatment alternatives. PMID- 27688769 TI - Immunogenicity of RSV F DNA Vaccine in BALB/c Mice. AB - Respiratory syncytial virus (RSV) causes severe acute lower respiratory tract disease leading to numerous hospitalizations and deaths among the infant and elderly populations worldwide. There is no vaccine or a less effective drug available against RSV infections. Natural RSV infection stimulates the Th1 immune response and activates the production of neutralizing antibodies, while earlier vaccine trials that used UV-inactivated RSV exacerbated the disease due to the activation of the allergic Th2 response. With a focus on Th1 immunity, we developed a DNA vaccine containing the native RSV fusion (RSV F) protein and studied its immune response in BALB/c mice. High levels of RSV specific antibodies were induced during subsequent immunizations. The serum antibodies were able to neutralize RSV in vitro. The RSV inhibition by sera was also shown by immunofluorescence analyses. Antibody response of the RSV F DNA vaccine showed a strong Th1 response. Also, sera from RSV F immunized and RSV infected mice reduced the RSV infection by 50% and 80%, respectively. Our data evidently showed that the RSV F DNA vaccine activated the Th1 biased immune response and led to the production of neutralizing antibodies, which is the desired immune response required for protection from RSV infections. PMID- 27688771 TI - Phosphate Solubilization Potential of Rhizosphere Fungi Isolated from Plants in Jimma Zone, Southwest Ethiopia. AB - Phosphorus (P) is one of the major bioelements limiting agricultural production. Phosphate solubilizing fungi play a noteworthy role in increasing the bioavailability of soil phosphates for plants. The present study was aimed at isolating and characterizing phosphate solubilizing fungi from different rhizospheres using both solid and liquid Pikovskaya (PVK) medium. A total of 359 fungal isolates were obtained from 150 rhizosphere soil samples of haricot bean, faba bean, cabbage, tomato, and sugarcane. Among the isolates, 167 (46.52%) solubilized inorganic phosphate. The isolated phosphate solubilizing fungi belonged to genera of Aspergillus (55.69%), Penicillium spp. (23.35%), and Fusarium (9.58%). Solubilization index (SI) ranged from 1.10 to 3.05. Isolates designated as JUHbF95 (Aspergillus sp.) and JUFbF59 (Penicillium sp.) solubilized maximum amount of P 728.77 MUg.mL(-1) and 514.44 MUg mL(-1), respectively, from TCP (tricalcium phosphate) after 15 days of incubation. The highest (363 MUg mL( 1)) soluble-P was released from RP with the inoculation of JUHbF95 in the PVK broth after 10 days of incubation. The present study indicated the presence of diverse plant associated P-solubilizing fungi that may serve as potential biofertilizers. PMID- 27688768 TI - Dysregulation of Notch and ERalpha signaling in AhR-/- male mice. AB - The aryl hydrocarbon receptor (AhR) is now recognized as an important physiological regulator in the immune and reproductive systems, and in the development of the liver and vascular system. AhR regulates cell cycle, cell proliferation, and differentiation through interacting with other signaling pathways, like estrogen receptor alpha (ERalpha), androgen receptor (AR), and Notch signaling. In the present study, we investigated Notch and estrogen signaling in AhR-/- mice. We found low fertility with degenerative changes in the testes, germ cell apoptosis, and a reduced number of early spermatids. There was no change in aromatase, AR, ERalpha, or ERbeta expression in the testis and no detectable change in serum estrogen levels. However, expression of Notch receptors (Notch1 and Notch3) and their target Hairy and Enhancer of Split homolog 1 (HES1) was reduced. In addition, the testosterone level was slightly reduced in the serum. In the mammary fat pad, AhR appeared to regulate estrogen signaling because, in AhR-/- males, there was significant growth of the mammary ducts with high expression of ERalpha in the ductal epithelium. The enhanced mammary ductal growth appears to be related to overexpression of ERalpha accompanied by a high proliferation index, whereas the reduced fertility appears to be related defects in Notch signaling that leads to reduced expression of HES1 and, consequently, early maturation of spermatocytes and a depletion of primary spermatids. Previous reports have indicated that AhR pathway is associated with infertility in men. Our results provide a mechanistic explanation for this defect. PMID- 27688770 TI - A High-Throughput Size Exclusion Chromatography Method to Determine the Molecular Size Distribution of Meningococcal Polysaccharide Vaccine. AB - Molecular size distribution of meningococcal polysaccharide vaccine is a readily identifiable parameter that directly correlates with the immunogenicity. In this paper, we report a size exclusion chromatography method to determine the molecular size distribution and distribution coefficient value of meningococcal polysaccharide serogroups A, C, W, and Y in meningococcal polysaccharide (ACWY) vaccines. The analyses were performed on a XK16/70 column packed with sepharose CL-4B with six different batches of Ingovax(r) ACWY, a meningococcal polysaccharide vaccine produced by Incepta Vaccine Ltd., Bangladesh. A quantitative rocket immunoelectrophoresis assay was employed to determine the polysaccharide contents of each serogroup. The calculated distribution coefficient values of serogroups A, C, W, and Y were found to be 0.26 +/- 0.16, 0.21 +/- 0.11, 0.21 +/- 0.11, and 0.14 +/- 0.12, respectively, and met the requirements of British Pharmacopeia. The method was proved to be robust for determining the distribution coefficient values which is an obligatory requirement for vaccine lot release. PMID- 27688772 TI - Herbal Medicines and Ovarian Hyperstimulation Syndrome: A Retrospective Cohort Study. AB - Background. The aim of this study was to assess the association between herbal medication and OHSS. Methods. This retrospective cohort study was conducted with 101 polycystic ovary syndrome patients. 66 patients took conventional pharmacological medications and 35 took herbal medications. Data were analyzed by statistical test including Fisher's Exact and binominal logistic regression. P < 0.05 was considered significant. Results. Of the 101 females, 53 were married and 48 were single. There was no significant association between the groups in marriage. No significant association was found in mean age between the two groups (23.9 +/- 5.8 years in the control group versus 26.3 +/- 6.7 years in the case group). There was a significant difference between the two groups .After adding the dependent (OHSS prevalence) and independent (marriage and group) variables into the model, the Hosmer-Lemeshow test showed suitability. Variances analyzed with this model ranged between 29.4% and 40.7%. Conclusion. The indiscriminate use of herbs is correlated with OHSS. Because patients increasingly consume herbs, they should be aware of potential side effects. However, appropriate dosages of herbs could be obtained for use instead of conventional treatments, which often have side effects. PMID- 27688773 TI - Defining the extreme substrate specificity of Euonymus alatus diacylglycerol acetyltransferase, an unusual membrane-bound O-acyltransferase. AB - Euonymus alatus diacylglycerol acetyltransferase (EaDAcT) synthesizes the unusually structured 3-acetyl-1,2-diacylglycerols (acetyl-TAG) found in the seeds of a few plant species. A member of the membrane-bound O-acyltransferase (MBOAT) family, EaDAcT transfers the acetyl group from acetyl-CoA to sn-1,2 diacylglycerol (DAG) to produce acetyl-TAG. In vitro assays demonstrated that the enzyme is also able to utilize butyryl-CoA and hexanoyl-CoA as acyl donors, though with much less efficiency compared with acetyl-CoA. Acyl-CoAs longer than eight carbons were not used by EaDAcT. This extreme substrate specificity of EaDAcT distinguishes it from all other MBOATs which typically catalyze the transfer of much longer acyl groups. In vitro selectivity experiments revealed that EaDAcT preferentially acetylated DAG molecules containing more double bonds over those with less. However, the enzyme was also able to acetylate saturated DAG containing medium chain fatty acids, albeit with less efficiency. Interestingly, EaDAcT could only acetylate the free hydroxyl group of sn-1,2-DAG but not the available hydroxyl groups in sn-1,3-DAG or in monoacylglycerols (MAG). Consistent with its similarity to the jojoba wax synthase, EaDAcT could acetylate fatty alcohols in vitro to produce alkyl acetates. Likewise, when coexpressed in yeast with a fatty acyl-CoA reductase capable of producing fatty alcohols, EaDAcT synthesized alkyl acetates although the efficiency of production was low. This improved understanding of EaDAcT specificity confirms that the enzyme preferentially utilizes acetyl-CoA to acetylate sn-1,2-DAGs and will be helpful in engineering the production of acetyl-TAG with improved functionality in transgenic plants. PMID- 27688774 TI - Successful Tocilizumab Therapy for Macrophage Activation Syndrome Associated with Adult-Onset Still's Disease: A Case-Based Review. AB - We report the case of a 71-year-old Japanese woman with adult-onset Still's disease (AOSD) in whom macrophage activation syndrome (MAS) developed despite therapy with oral high-dose prednisolone and intravenous methylprednisolone pulse therapy twice. She was successfully treated with tocilizumab (TCZ). Soon afterward, her fever ceased and high levels of both ferritin and C-reactive protein levels decreased. Her course was complicated by disseminated intravascular coagulation, cytomegalovirus infection, and Pneumocystis jirovecii pneumonia. After these were resolved, AOSD-associated MAS was well controlled. She was discharged on hospital day 87. Although biologics such as TCZ are becoming established for the treatment of AOSD, there is no recommended therapy for AOSD-associated MAS. Several biologics have been tried for this complication, but their efficacy and safety remain controversial. We reviewed reported cases of AOSD-associated MAS successfully treated with various biologics. TCZ initiation after adequate nonselective immunosuppressive therapy, such as methylprednisolone pulse therapy or a prednisolone-based combination of immunosuppressants, can be an effective treatment for AOSD-associated MAS. On the other hand, biologics given after insufficient immunosuppressive therapy may cause MAS. A strategy combining adequate immunosuppression and a biologic could be safe if special attention is given to adverse events such as opportunistic infections or biologic associated MAS. PMID- 27688775 TI - High-Fidelity Reprogrammed Human IPSCs Have a High Efficacy of DNA Repair and Resemble hESCs in Their MYC Transcriptional Signature. AB - Human induced pluripotent stem cells (hiPSCs) are reprogrammed from adult or progenitor somatic cells and must make substantial adaptations to ensure genomic stability in order to become "embryonic stem cell- (ESC-) like." The DNA damage response (DDR) is critical for maintenance of such genomic integrity. Herein, we determined whether cell of origin and reprogramming method influence the DDR of hiPSCs. We demonstrate that hiPSCs derived from cord blood (CB) myeloid progenitors (i.e., CB-iPSC) via an efficient high-fidelity stromal-activated (sa) method closely resembled hESCs in DNA repair gene expression signature and irradiation-induced DDR, relative to hiPSCs generated from CB or fibroblasts via standard methods. Furthermore, sa-CB-iPSCs also more closely resembled hESCs in accuracy of nonhomologous end joining (NHEJ), DNA double-strand break (DSB) repair, and C-MYC transcriptional signatures, relative to standard hiPSCs. Our data suggests that hiPSCs derived via more efficient reprogramming methods possess more hESC-like activated MYC signatures and DDR signaling. Thus, an authentic MYC molecular signature may serve as an important biomarker in characterizing the genomic integrity in hiPSCs.

AB - Neural stem cells (NSCs) have a high potency for differentiation to neurons and glial cells for replacement of damaged cells and paracrine effects for the regeneration and remyelination of host axons. Dental pulp is known to have a potential to differentiate into neural-like cells; therefore, dental pulp may be used as an autologous cell source for neural repair. In this study, we selectively expanded stem cells from human dental pulp in an initial culture using NSC media under xeno- and serum-free conditions. At the initial step of primary culture, human dental pulp was divided into two groups according to the culture media: 10% fetal bovine serum medium group (FBS group) and NSC culture medium group (NSC group). In the NSC group relative to the FBS group, the expression of NSC markers and the concentrations of leukemia inhibitory factor, nerve growth factor, and stem cell factor were higher, although their expression levels were lower than those of human fetal NSCs. The transplanted cells of the NSC group survived well within the normal brain and injured spinal cord of rats and expressed nestin and Sox2. Under the xeno- and serum-free conditions, autologous human dental pulp-derived stem cells might prove useful for clinical cell-based therapies to repair damaged neural tissues.

PMID- 27688777 TI - The Neurovascular Properties of Dental Stem Cells and Their Importance in Dental Tissue Engineering. AB - Within the field of tissue engineering, natural tissues are reconstructed by combining growth factors, stem cells, and different biomaterials to serve as a scaffold for novel tissue growth. As adequate vascularization and innervation are essential components for the viability of regenerated tissues, there is a high need for easily accessible stem cells that are capable of supporting these functions. Within the human tooth and its surrounding tissues, different stem cell populations can be distinguished, such as dental pulp stem cells, stem cells from human deciduous teeth, stem cells from the apical papilla, dental follicle stem cells, and periodontal ligament stem cells. Given their straightforward and relatively easy isolation from extracted third molars, dental stem cells (DSCs) have become an attractive source of mesenchymal-like stem cells. Over the past decade, there have been numerous studies supporting the angiogenic, neuroprotective, and neurotrophic effects of the DSC secretome. Together with their ability to differentiate into endothelial cells and neural cell types, this makes DSCs suitable candidates for dental tissue engineering and nerve injury repair.

AB - Background. The Scale for Psychosocial Factors in Food Allergy (SPS-FA) is based on the biopsychosocial model of health and was developed and validated in Chile to measure the interaction between psychological variables and allergy symptoms in the child. We sought to validate this scale in an English speaking population and explore its relationship with parental quality of life, self-efficacy, and mental health. Methods. Parents (n = 434) from the general population in the UK, who had a child with a clinical diagnosis of food allergy, completed the SPS-FA and validated scales on food allergy specific parental quality of life (QoL), parental self-efficacy, and general mental health. Findings. The SPS-FA had good internal consistency (alphas = .61-.86). Higher scores on the SPS-FA significantly correlated with poorer parental QoL, self-efficacy, and mental health. All predictors explained 57% of the variance in SPS-FA scores with QoL as the biggest predictor (beta = .52). Discussion. The SPS-FA is a valid scale for use in the UK and provides a holistic view of the impact of food allergy on the family. In conjunction with health-related QoL measures, it can be used by health care practitioners to target care for patients and evaluate psychological interventions for improvement of food allergy management. PMID- 27688787 TI - Bioenergy and Breast Cancer: A Report on Tumor Growth and Metastasis. AB - As many as 80% of the 296,000 women and 2,240 men diagnosed with breast cancer in the United States will seek out complementary and alternative medicine (CAM) treatments. One such therapy is Healing Touch (HT), recognized by the National Center for Complementary and Integrative Health (NCCIH) as a treatment modality. Using a multiple experimental groups design, fifty-six six- to eight-week-old Balb/c mice were injected with 4T1 breast cancer tumor cells and randomly divided into intervention and positive control groups. Five days after tumor cell injection, mice in the intervention groups received HT either daily or every other day for 10 minutes by one HT practitioner. At 15 days after tumor cell injection, tumor size was measured, and metastasis was evaluated by a medical pathologist after necropsy. Tumor size did not differ significantly among the groups (F(3,52) = 0.75, p value = 0.53). The presence of metastasis did not differ across groups (chi-square(3) = 3.902, p = 0.272) or when compared within an organ (liver: chi-square(3) = 2.507, p = 0.474; lungs: chi-square(3) = 3.804, p = 0.283; spleen: chi-square(3) = 0.595, p = 0.898). However, these results did indicate a moderate, though insignificant, positive impact of HT and highlight the need for continued research into dose, length of treatment, and measurable outcomes (tumor size, metastasis) to provide evidence to suggest application for nursing care. PMID- 27688786 TI - Differential effects of hydrocortisone, prednisone, and dexamethasone on hormonal and pharmacokinetic profiles: a pilot study in children with congenital adrenal hyperplasia. AB - BACKGROUND: Little is known about the comparative effects of different glucocorticoids on the adrenal and growth hormone (GH) axes in children with congenital adrenal hyperplasia (CAH). We sought to compare the effects of hydrocortisone (HC), prednisone (PDN), and dexamethasone (DEX) in children with classic CAH and to investigate a potential role of pharmacogenetics. METHODS: Subjects were randomly assigned to three sequential 6-week courses of HC, PDN, and DEX, each followed by evaluation of adrenal hormones, IGF-1, GH, and body mass index (BMI). Single nucleotide polymorphism (SNP) analysis of genes in the glucocorticoid pathway was also performed. RESULTS: Nine prepubertal subjects aged 8.1 +/- 2.3 years completed the study. Mean ACTH, androstenedione, and 17 hydroxyprogesterone (17-OHP) values were lower following the DEX arm of the study than after subjects received HC (p <= 0.016) or PDN (p <= 0.002). 17-OHP was also lower after HC than PDN (p < 0.001). There was no difference in IGF-1, GH, or change in BMI. SNP analysis revealed significant associations between hormone concentrations, pharmacokinetic parameters, and variants in several glucocorticoid pathway genes (ABCB1, NR3C1, IP013, GLCCI1). CONCLUSIONS: DEX resulted in marked adrenal suppression suggesting that its potency relative to hydrocortisone and prednisone was underestimated. SNPs conferred significant differences in responses between subjects. Although preliminary, these pilot data suggest that incorporating pharmacogenetics has the potential to eventually lead to targeted therapy in children with CAH. PMID- 27688788 TI - Baicalin Attenuates Hypoxia-Induced Pulmonary Arterial Hypertension to Improve Hypoxic Cor Pulmonale by Reducing the Activity of the p38 MAPK Signaling Pathway and MMP-9. AB - Baicalin has a protective effect on hypoxia-induced pulmonary hypertension in rats, but the mechanism of this effect remains unclear. Thus, investigating the potential mechanism of this effect was the aim of the present study. Model rats that display hypoxic pulmonary hypertension and cor pulmonale under control conditions were successfully generated. We measured a series of indicators to observe the levels of pulmonary arterial hypertension, pulmonary arteriole remodeling, and right ventricular remodeling. We assessed the activation of p38 mitogen-activated protein kinase (MAPK) in the pulmonary arteriole walls and pulmonary tissue homogenates using immunohistochemistry and western blot analyses, respectively. The matrix metalloproteinase- (MMP-) 9 protein and mRNA levels in the pulmonary arteriole walls were measured using immunohistochemistry and in situ hybridization. Our results demonstrated that baicalin not only reduced p38 MAPK activation in both the pulmonary arteriole walls and tissue homogenates but also downregulated the protein and mRNA expression levels of MMP 9 in the pulmonary arteriole walls. This downregulation was accompanied by the attenuation of pulmonary hypertension, arteriole remodeling, and right ventricular remodeling. These results suggest that baicalin may attenuate pulmonary hypertension and cor pulmonale, which are induced by chronic hypoxia, by downregulating the p38 MAPK/MMP-9 pathway. PMID- 27688790 TI - Herb-Drug Interaction: Effects of Relinqing(r) Granule on the Pharmacokinetics of Ciprofloxacin, Sulfamethoxazole, and Trimethoprim in Rats. AB - Relinqing granule (RLQ) is the best-selling Chinese patent drug for treatment of urinary system diseases. In this study, the effects of RLQ on the pharmacokinetics of ciprofloxacin, sulfamethoxazole, and trimethoprim in SD rats were investigated. Rats were randomly divided into control group 1, control group 2, RLQ group 1, and RLQ group 2. RLQ group 1 and RLQ group 2 were treated orally with RLQ for 7 days, and rats were treated with the same volume of water in control group 1 and control group 2. Then, RLQ group 1 and control group 1 were given intragastrically ciprofloxacin on day 8, while RLQ group 2 and control group 2 were given intragastrically sulfamethoxazole and trimethoprim on day 8. Blood samples were collected and determined. There was no significant influence of pharmacokinetic parameters of trimethoprim on two groups. But some pharmacokinetic parameters of ciprofloxacin and sulfamethoxazole in RLQ pretreated rats were evidently altered (P < 0.05), which indicated that absorption of ciprofloxacin and sulfamethoxazole in RLQ pretreated rats was significantly affected. It indicated the coadministration of RLQ would have an influence on the efficacy of ciprofloxacin and sulfamethoxazole, and the doses of ciprofloxacin tablet and compound sulfamethoxazole tablet need adjustment. PMID- 27688789 TI - Application of Traditional Chinese Medical Herbs in Prevention and Treatment of Respiratory Syncytial Virus. AB - Respiratory syncytial virus (RSV) is a common viral pathogen of the lower respiratory tract, which, in the absence of effective management, causes millions of cases of severe illness per year. Many of these infections develop into fatal pneumonia. In a review of English and Chinese medical literature, recent traditional Chinese medical herb- (TCMH-) based progress in the area of prevention and treatment was identified, and the potential anti-RSV compounds, herbs, and formulas were explored. Traditional Chinese medical herbs have a positive effect on inhibiting viral attachment, inhibiting viral internalization, syncytial formation, alleviation of airway inflammation, and stimulation of interferon secretion and immune system; however, the anti-RSV mechanisms of TCMHs are complicated, which should be further investigated. PMID- 27688791 TI - Acupuncture Decreases Blood Pressure Related to Hypothalamus Functional Connectivity with Frontal Lobe, Cerebellum, and Insula: A Study of Instantaneous and Short-Term Acupuncture Treatment in Essential Hypertension. AB - The therapeutic effects of acupuncture in decreasing blood pressure are ambiguous and underlying acupuncture in hypertension treatment has not been investigated. Our objective was to observe the change of quality of life and compare the differences in brain functional connectivity by investigating instantaneous and short-term acupuncture treatment in essential hypertension patients. A total of 30 patients were randomly divided into the LR3 group and sham acupoint group. Subjects received resting-state fMRI among preacupuncture, postinstantaneous, and short-term acupuncture treatment in two groups. Hypothalamus was selected as the seed point to analyze the changes in connectivity. We found three kinds of results: (1) There was statistical difference in systolic blood pressure in LR3 group after the short-term treatment and before acupuncture. (2) Compared with sham acupoint, acupuncture at LR3 instantaneous effects in the functional connectivity with seed points was more concentrated in the frontal lobe. (3) Compared with instantaneous effects, acupuncture LR3 short-term effects in the functional connectivity with seed points had more regions in frontal lobe, cerebellum, and insula. These brain areas constituted a neural network structure with specific functions that could explain the mechanism of therapy in hypertension patients by LR3 acupoint.

To study the effect of Heweianshen decoction (HAD) on orexin-A and cholecystokinin-8 (CCK-8) expression in rat models of insomnia caused by injecting parachlorophenylalanine (PCPA) intraperitoneally. Methods. Fifty male Wistar rats were randomly divided into five groups (10 rats in each group): blank group, model group, and low-, medium-, and high-dose HAD-treated groups. A rat model of insomnia was established by injecting intraperitoneally with PCPA (300 mg/kg body weight). Rats were given normal saline (10 mL/kg) or 5.25, 10.5, and 21 g/kg HAD by intragastric administration once a day for 6 days. After that, the rats were sacrificed to collect the hypothalamus for tests, using radioimmunoassay to detect the expression of orexin-A and CCK-8. Results. Heweianshen decoction reduced the expression of orexin-A and increased the expression of CCK-8 in the hypothalamus of rat model of insomnia. Conclusion. The therapeutic effect of HAD on insomnia is partially attributed to the decreased expression of orexin-A and increased expression of CCK-8.

AB - PURPOSES: The aim of this study was to determine the effects of nutritional status at the start of highly active anti-retroviral therapy on treatment outcomes among HIV/AIDS patients taking HAART at Jimma University Specialized Hospital. METHODS: We performed a retrospective cohort study involving 340 adults who started highly active anti-retroviral therapy. The patients have been clinically followed for 2 years. Data were extracted from paper based medical charts by trained data collectors from January 30 to February 28, 2014 using data collection format. We entered data into Epi data version 3.1 and then exported to SPSS for windows version 21. Predictors of CD4 change were identified using multivariable linear regression model. Time to an event (death) was estimated by Kaplan-Meier and predictors of mortality were identified by Cox proportional hazard model. RESULTS: Out of 340 patients, 42 patients died during the follow up. Twenty-five (59.5 %) deaths were from malnourished group. Age, baseline CD4, sex, baseline HAART and marital status were significant predictors of immunologic recovery at different time points. Malnutrition was associated with lower CD4 recovery and greater hazard of death. CONCLUSIONS: Malnutrition tends to decrease CD4 recovery and predisposes patient to early death. PMID- 27688794 TI - Targeting vulnerable populations: a synthetic review on alcohol use and risky sexual behaviour among migrant populations. AB - BACKGROUND: Research has demonstrated a link between alcohol use and risky sexual behaviour among different types of migrant populations. Therefore, research investigating risk factors associated with alcohol consumption among them is a public health priority. This review aimed to explore the intersection between migration, alcohol consumption and risky sexual behaviour. METHODS: This article is a synthetic review of empirical studies on the association of alcohol and high risk sexual behaviour among different types of the migrant populations, focusing on measurable outcomes generated from quantitative data. A descriptive analysis generated from global and situational studies was used to interpret the reviewed research and to discuss critically the factors that drive migrants to engage in alcohol consumption and high-risk behaviour. RESULTS: This review found out that there is a significant and positive association between global and situational alcohol use and several outcomes of risky sexual behaviour among different types of migrant populations. This association was however mainly observed at high quantities and frequencies of alcohol use, mainly among male migrants, and was often tied to a specific situation or context, for instance the type of sexual partner, the level of mobility and to environmental factors such as living arrangements and entertainment venues. CONCLUSIONS: The study supports previous research that alcohol use is associated with risky sexual behaviour among different types of migrant populations. Therefore, future interventions should target mobile, male migrant heavy drinkers. Additional research is needed using more event-level and longitudinal methodologies that overcome prior methodological limitations. PMID- 27688796 TI - Analysis of gene copy number changes in tumor phylogenetics. AB - BACKGOUND: Evolution of cancer cells is characterized by large scale and rapid changes in the chromosomal landscape. The fluorescence in situ hybridization (FISH) technique provides a way to measure the copy numbers of preselected genes in a group of cells and has been found to be a reliable source of data to model the evolution of tumor cells. Chowdhury et al. (Bioinformatics 29(13):189-98, 23; PLoS Comput Biol 10(7):1003740, 24) recently develop a computational model for tumor progression driven by gains and losses in cell count patterns obtained by FISH probes. Their model aims to find the rectilinear Steiner minimum tree (RSMT) (Chowdhury et al. in Bioinformatics 29(13):189-98, 23) and the duplication Steiner minimum tree (DSMT) (Chowdhury et al. in PLoS Comput Biol 10(7):1003740, 24) that describe the progression of FISH cell count patterns over its branches in a parsimonious manner. Both the RSMT and DSMT problems are NP-hard and heuristics are required to solve the problems efficiently. METHODS: In this paper we propose two approaches to solve the RSMT problem, one inspired by iterative methods to address the "small phylogeny" problem (Sankoff et al. in J Mol Evol 7(2):133-49, 27; Blanchette et al. in Genome Inform 8:25-34, 28), and the other based on maximum parsimony phylogeny inference. We further show how to extend these heuristics to obtain solutions to the DSMT problem, that models large scale duplication events. RESULTS: Experimental results from both simulated and real tumor data show that our methods outperform previous heuristics (Chowdhury et al. in Bioinformatics 29(13):189-98, 23; Chowdhury et al. in PLoS Comput Biol 10(7):1003740, 24) in obtaining solutions to both RSMT and DSMT problems. CONCLUSION: The methods introduced here are able to provide more parsimony phylogenies compared to earlier ones which are consider better choices. PMID- 27688797 TI - Narrative descriptions of miyo-mahcihoyan (physical, emotional, mental, and spiritual well-being) from a contemporary nehiyawak (Plains Cree) perspective. AB - BACKGROUND: There are unequivocal health disparities, both physical and mental, between the Indigenous and non-Indigenous peoples of Canada. METHODS: Utilizing narrative inquiry, 15 nehiyawak (Plains Cree people) between 18 and 71 years of age from Thunderchild First Nation were interviewed to explore what improved their mental health and well-being and what they needed to attain optimal mental health and well-being. By posing questions that focused on the positive, the strengths and resilience of the nehiyawak came to the forefront. RESULTS: Narrative thematic analysis of interview data consistently revealed four overarching themes that highlighted what positively impacted nehiyawak mental health and well-being and their perceived needs to attain optimal mental health and well-being: relationships; spiritual beliefs and cultural practices; tanisisi wapahtaman pimatisiwin (worldview); and ekwa ohi kikwaya piko ka-ispayiki kispin ka-nohte-miyo-mahcihoyan (these are the things that need to happen if I want to be healthy). The nehiyawak in this study described holistic health determinants that correlate with the medicine wheel and the determinants of health, and described these holistic health determinants as making a positive difference to their mental health and as necessary for them to obtain optimal mental health and well-being. CONCLUSIONS: These results suggest that mental health programming and interventions should be harmonious with Indigenous culture; utilize a holistic approach that takes physical, emotional, mental, and spiritual well-being into consideration; and address the existing mental health disparities using the determinants of health as a framework, with an increased focus on the current socio-economic status of Indigenous peoples in Canada. PMID- 27688795 TI - Fungal cell wall agents and bacterial lipopolysaccharide in organic dust as possible risk factors for pulmonary sarcoidosis. AB - BACKGROUND: Composition of organic dust is very complex, involving particles of microbial, animal and plant origin. Several environmental exposure studies associate microbial cell wall agents in organic dust with various respiratory symptoms and diseases. The aim of the present study was to investigate the in vitro effects of the co-exposure of fungal cell wall agents (FCWAs) and bacterial lipopolysaccharide (LPS) on inflammatory immune responses of peripheral blood mononuclear cells (PBMCs) from patients with pulmonary sarcoidosis. METHODS: PBMCs from 22 patients with pulmonary sarcoidosis and 20 healthy subjects were isolated and stimulated in vitro with FCWAs (soluble and particulate (1 -> 3) beta-D-glucan, zymosan and chitosan) and/or LPS. Subsequently, cytokines were measured by ELISA and the mRNA expression of dectin-1, toll-like receptor 2 (TLR2), TLR4 and mannose receptor (MR) was analysed by real-time RT-PCR. RESULTS: Patients with sarcoidosis had a significantly higher secretion of inflammatory cytokines tumour necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), IL-10 and IL-12 (1.7-fold, 2.0-fold, 2.2-fold, and 2.8-fold, respectively; all p < 0.05) after in vitro co-stimulation of PBMCs with FCWAs and LPS. We showed that PBMCs from patients with sarcoidosis had a higher baseline mRNA expression of dectin-1, TLR2, TLR4 and MR (6-fold, 11-fold, 18-fold, and 4-fold, respectively). Furthermore, we found a reduced expression of dectin-1, TLR2 and TLR4 after stimulation with FCWAs and/or LPS, although the reduction was significantly weaker in patients than in healthy subjects. CONCLUSIONS: In conclusion, co stimulation with FCWAs and LPS of PBMC from patients with sarcoidosis caused a weaker reduction of dectin-1, TLR2, TLR4 receptors expression, which could increase the sensitivity of PBMCs, leading to excessive inflammatory cytokine responses and result in the development or progression of pulmonary sarcoidosis. PMID- 27688798 TI - Feasibility of an interactive voice response system for monitoring depressive symptoms in a lower-middle income Latin American country. AB - BACKGROUND: Innovative, scalable solutions are needed to address the vast unmet need for mental health care in low- and middle-income countries (LMICs). METHODS: We conducted a feasibility study of a 14-week automated telephonic interactive voice response (IVR) depression self-care service among Bolivian primary care patients with at least moderately severe depressive symptoms. We analyzed IVR call completion rates, the reliability and validity of IVR-collected data, and participant satisfaction. RESULTS: Of the 32 participants, the majority were women (78 % or 25/32) and non-indigenous (75 % or 24/32). Participants had moderate depressive symptoms at baseline (PHQ-8 score mean 13.3, SD = 3.5) and reported good or fair general health status (88 % or 28/32). Fifty-four percent of weekly IVR calls (approximately 7 out of 13 active call-weeks) were completed. Neither PHQ-8 scores nor IVR call completion differed significantly by ethnicity, education, self-reported depression diagnosis, self-reported overall health, number of chronic conditions, or health literacy. The reliability for IVR collected PHQ-8 scores was good (Cronbach's alpha = 0.83). Virtually every participant (97 %) was "mostly" or "very" satisfied with the program. Many described the program as beneficial for their mood and self-care, albeit limited by some technological difficulties and the lack of human interaction. CONCLUSION: Findings suggest that IVR could feasibly be used to provide monitoring and self care education to depressed patients in Bolivia. An expanded stepped-care service offering contact with lay health workers for more depressed individuals and expanded mHealth content may foster greater patient engagement and enhance its therapeutic value while remaining cost-effective.

PMID- 27688799 TI - The associations of cumulative adverse childhood experiences and irritability with mental disorders in detained male adolescent offenders. AB - BACKGROUND: Adverse childhood experiences (ACEs) and psychiatric disorders are common in juvenile detainees. Emotional dysregulation resulting from cumulated ACEs may be characterized by symptoms of irritability. The present study examined whether the accumulation of ACEs, irritability, or both predicted mental disorders in incarcerated adolescents with and without controlling for one another and for socio-demographic factors. METHODS: One hundred thirty male detained juvenile offenders (aged 13.8-19.5 years) were assessed by structured clinical interviews and a self-reporting scale for irritability. Univariate and multivariate regression models were used to examine the shared and distinct associations of ACEs and irritability with psychiatric diagnoses. RESULTS: A total of 75 % of the participants reported more than one ACE. The ACE total score was positively related to self-reported irritability. The ACE total score predicted depressive disorders, suicidality, post-traumatic stress disorder (PTSD), and anxiety disorders. Irritability was positively related to depressive disorders, suicidality, disruptive behavior disorder (DBD), substance use disorder (SUD), and attention deficit hyperactivity disorder (ADHD). These associations remained significant in multivariate models. CONCLUSIONS: This study provides evidence for the predictive impact of self-reported ACEs and irritability with regard to adolescent psychiatric disorders in young male inmates. Both variables differed in their predictive power for PTSD, internalizing, and externalizing disorders indicating the need for specific therapeutic interventions. Taking a close look at their trauma history seems to be of special importance for juveniles suffering from PTSD and anxiety disorders. For delinquent adolescents with DBD, ADHD and SUD, the training of emotion regulation techniques appears most promising. Approaches focusing on both, ACEs and emotion-focused contents may be implemented in the treatment of depressive disorders and suicidality. PMID- 27688801 TI - Design and integration of a problem-based biofabrication course into an undergraduate biomedical engineering curriculum. AB - BACKGROUND: The rapidly evolving discipline of biological and biomedical engineering requires adaptive instructional approaches that teach students to target and solve multi-pronged and ill-structured problems at the cutting edge of scientific research. Here we present a modular approach to designing a lab-based course in the emerging field of biofabrication and biological design, leading to a final capstone design project that requires students to formulate and test a hypothesis using the scientific method. RESULTS: Students were assessed on a range of metrics designed to evaluate the format of the course, the efficacy of the format for teaching new topics and concepts, and the depth of the contribution this course made to students training for biological engineering careers. The evaluation showed that the problem-based format of the course was well suited to teaching students how to use the scientific method to investigate and uncover the fundamental biological design rules that govern the field of biofabrication. CONCLUSIONS: We show that this approach is an efficient and effective method of translating emergent scientific principles from the lab bench to the classroom and training the next generation of biological and biomedical engineers for careers as researchers and industry practicians. PMID- 27688802 TI - Hydroxyurea: a new old therapy for Langerhans cell histiocytosis. PMID- 27688803 TI - Antigen modulation as a potential mechanism of anti-KEL immunoprophylaxis in mice. AB - Red blood cell (RBC) alloimmunization is a serious complication of transfusion or pregnancy. Despite the widespread use of Rh immune globulin to prevent pregnancy associated anti-D alloimmunization, its mechanism of action remains elusive. We have previously described a murine model in which immunoprophylaxis with polyclonal anti-KEL sera prevents alloimmunization in wild-type recipients transfused with transgenic murine RBCs expressing the human KEL glycoprotein. To investigate the mechanism of action, we have now evaluated the outcome of immunoprophylaxis treatment in mice lacking Fcgamma receptors (FcgammaRs), complement (C3), both, or none. Whereas polyclonal anti-KEL sera completely prevented alloimmunization in wild-type and single-knockout (KO) mice lacking FcgammaRs or C3, double-KO mice lacking both FcgammaRs and C3 became alloimmunized despite immunoprophylaxis. Rapid clearance of essentially all transfused RBCs with detectable KEL glycoprotein antigen occurred within 24 hours in wild-type and single-KO recipients treated with immunoprophylaxis, with the transfused RBCs remaining in circulation having minimal KEL glycoprotein antigen detectable by flow cytometry or western blot. In contrast, transfused RBCs with the KEL glycoprotein antigen fully intact continued to circulate for days in double-KO mice despite treatment with immunoprophylaxis. Further, in vitro phagocytosis assays showed no consumption of opsonized murine RBCs by double-KO splenocytes. Taken in combination, our data suggest that modulation of the KEL antigen (and potentially RBC clearance) by redundant recipient pathways involving both FcgammaRs and C3 may be critical to the mechanism of action of polyclonal anti-KEL immunoprophylaxis. These findings could have implications for the development of immunoprophylaxis programs in humans. PMID- 27688807 TI - How to perform a root cause analysis for workup and future prevention of medical errors: a review. AB - Providing quality patient care is a basic tenant of medical and surgical practice. Multiple orthopaedic programs, including The Patient Safety Committee of the American Academy of Orthopaedic Surgeons (AAOS), have been implemented to measure quality of surgical care, as well as reduce the incidence of medical errors. Structured Root Cause Analysis (RCA) has become a recent area of interest and, if performed thoroughly, has been shown to reduce surgical errors across many subspecialties. There is a paucity of literature on how the process of a RCA can be effectively implemented. The current review was designed to provide a structured approach on how to conduct a formal root cause analysis. Utilization of this methodology may be effective in the prevention of medical errors. PMID- 27688806 TI - Comparative genomic, transcriptomic and secretomic profiling of Penicillium oxalicum HP7-1 and its cellulase and xylanase hyper-producing mutant EU2106, and identification of two novel regulatory genes of cellulase and xylanase gene expression. AB - BACKGROUND: The filamentous fungus Penicillium oxalicum is a potential alternative to Trichoderma reesei for industrial production of a complete cellulolytic enzyme system for a bio-refinery. Comparative omics approaches can support rational genetic engineering and/or breeding of filamentous fungi with improved cellulase production capacity. In this study, comparative genomic, transcriptomic and secretomic profiling of P. oxalicum HP7-1 and its cellulase and xylanase hyper-producing mutant EU2106 were employed to screen for novel regulators of cellulase and xylanase gene expression. RESULTS: The 30.62 Mb P. oxalicum HP7-1 genome was sequenced, and 9834 protein-coding genes were annotated. Re-sequencing of the mutant EU2106 genome identified 274 single nucleotide variations and 12 insertion/deletions. Comparative genomic, transcriptomic and secretomic profiling of HP7-1 and EU2106 revealed four candidate regulators of cellulase and xylanase gene expression. Deletion of these candidate genes and measurement of the enzymatic activity of the resultant mutants confirmed the identity of three regulatory genes. POX02484 and POX08522, encoding a putative Zn(II)2Cys6 DNA-binding domain and forkhead protein, respectively, were found to be novel, while PoxClrB is an ortholog of ClrB, a key transcriptional regulator of cellulolytic enzyme gene expression in filamentous fungi. DeltaPOX02484 and DeltaPOX08522 mutants exhibited significantly reduced beta-glucosidase activity, increased carboxymethylcellulose cellulase and xylanase activities, and altered transcription level of cellulase and xylanase genes compared with the parent strain DeltaPoxKu70, with Avicel as the sole carbon source. CONCLUSIONS: Two novel genes, POX02484 and POX08522, were found and characterized to regulate the expression of cellulase and xylanase genes in P. oxalicum. These findings are important for engineering filamentous fungi to improve cellulase and xylanase production. PMID- 27688804 TI - Reversible binding of hemoglobin to band 3 constitutes the molecular switch that mediates O2 regulation of erythrocyte properties. AB - Functional studies have shown that the oxygenation state of the erythrocyte regulates many important pathways, including glucose metabolism, membrane mechanical stability, and cellular adenosine triphosphate (ATP) release. Deoxyhemoglobin (deoxyHb), but not oxyhemoglobin, binds avidly and reversibly to band 3, the major erythrocyte membrane protein. Because band 3 associates with multiple metabolic, solute transport, signal transduction, and structural proteins, the hypothesis naturally arises that the O2-dependent regulation of erythrocyte properties might be mediated by the reversible association of deoxyHb with band 3. To explore whether the band 3-deoxyHb interaction constitutes a "molecular switch" for regulating erythrocyte biology, we have generated transgenic mice with mutations in the deoxyHb-binding domain of band 3. One strain of mouse contains a "humanized" band 3 in which the N-terminal 45 residues of mouse band 3 are replaced by the homologous sequence from human band 3, including the normal human band 3 deoxyHb-binding site. The second mouse contains the same substitution as the first, except the deoxyHb site on band 3 (residues 12-23) has been deleted. Comparison of these animals with wild-type mice demonstrates that the following erythrocyte properties are controlled by the O2 dependent association of hemoglobin with band 3: (1) assembly of a glycolytic enzyme complex on the erythrocyte membrane which is associated with a shift in glucose metabolism between the pentose phosphate pathway and glycolysis, (2) interaction of ankyrin with band 3 and the concomitant regulation of erythrocyte membrane stability, and (3) release of ATP from the red cell which has been linked to vasodilation.

AB - BACKGROUND: Metabolic engineering of cyanobacteria has enabled photosynthetic conversion of CO2 to value-added chemicals as bio-solar cell factories. However, the production levels of isoprenoids in engineered cyanobacteria were quite low, compared to other microbial hosts. Therefore, modular optimization of multiple gene expressions for metabolic engineering of cyanobacteria is required for the production of farnesyl diphosphate-derived isoprenoids from CO2. RESULTS: Here, we engineered Synechococcus elongatus PCC 7942 with modular metabolic pathways consisting of the methylerythritol phosphate pathway enzymes and the amorphadiene synthase for production of amorpha-4,11-diene, resulting in significantly increased levels (23-fold) of amorpha-4,11-diene (19.8 mg/L) in the best strain relative to a parental strain. Replacing amorphadiene synthase with squalene synthase led to the synthesis of a high amount of squalene (4.98 mg/L/OD730). Overexpression of farnesyl diphosphate synthase is the most critical factor for the significant production, whereas overexpression of 1-deoxy-d-xylulose 5 phosphate reductase is detrimental to the cell growth and the production. Additionally, the cyanobacterial growth inhibition was alleviated by expressing a terpene synthase in S. elongatus PCC 7942 strain with the optimized MEP pathway only (SeHL33). CONCLUSIONS: This is the first demonstration of photosynthetic production of amorpha-4,11-diene from CO2 in cyanobacteria and production of squalene in S. elongatus PCC 7942. Our optimized modular OverMEP strain (SeHL33) with either co-expression of ADS or SQS demonstrated the highest production levels of amorpha-4,11-diene and squalene, which could expand the list of farnesyl diphosphate-derived isoprenoids from CO2 as bio-solar cell factories.

PMID- 27688808 TI - 19p13.2 Microdeletion including NFIX associated with overgrowth and intellectual disability suggestive of Malan syndrome. AB - BACKGROUND: Overgrowth syndromes represent clinically and genetically heterogeneous conditions characterized by a wide spectrum of malformations, tall stature, intellectual disability and/or macrocephaly. RESULTS: In a cohort of four clinically characterized patients with overgrowth syndrome without known causative gene mutation, we performed an Illumina SNP-array analysis to identify the pathogenic copy number variations. We identified two rare copy number variations harboring overgrowth syndrome related genes. Patient 1 was Malan syndrome with a 1.4 Mb 19p13.2-13.13 microdeletion including NFIX, and Patient 2 was identified as Sotos syndrome with a 1.6 Mb 5q35.2 microdeletion encompassing NSD1. CONCLUSIONS: We identified two patients associated with Manlan syndrome and Sotos syndrome respectively. We also discuss the use of the microarrays-based candidate gene strategy in Mendelian disease-gene identification. PMID- 27688811 TI - ProtNN: fast and accurate protein 3D-structure classification in structural and topological space. AB - BACKGROUND: Studying the functions and structures of proteins is important for understanding the molecular mechanisms of life. The number of publicly available protein structures has increasingly become extremely large. Still, the classification of a protein structure remains a difficult, costly, and time consuming task. The difficulties are often due to the essential role of spatial and topological structures in the classification of protein structures. RESULTS: We propose ProtNN, a novel classification approach for protein 3D-structures. Given an unannotated query protein structure and a set of annotated proteins, ProtNN assigns to the query protein the class with the highest number of votes across the k nearest neighbor reference proteins, where k is a user-defined parameter. The search of the nearest neighbor annotated structures is based on a protein-graph representation model and pairwise similarities between vector embedding of the query and the reference protein structures in structural and topological spaces. CONCLUSIONS: We demonstrate through an extensive experimental evaluation that ProtNN is able to accurately classify several datasets in an extremely fast runtime compared to state-of-the-art approaches. We further show that ProtNN is able to scale up to a whole PDB dataset in a single-process mode with no parallelization, with a gain of thousands order of magnitude in runtime compared to state-of-the-art approaches. PMID- 27688810 TI - The tip of the iceberg: challenges of accessing hospital electronic health record data for biological data mining. AB - Modern cohort studies include self-reported measures on disease, behavior and lifestyle, sensor-based observations from mobile phones and wearables, and rich omics data. Follow-up is often achieved through electronic health record (EHR) linkages across primary and secondary healthcare providers. Historically however, researchers typically only get to see the tip of the iceberg: coded administrative data relating to healthcare claims which mainly record billable diagnoses and procedures. The rich data generated during the clinical pathway remain submerged and inaccessible. While some institutions and initiatives have made good progress in unlocking such deep phenotypic data within their institutional realms, access at scale still remains challenging. Here we outline and discuss the main technical and social challenges associated with accessing these data for data mining and hauling the entire iceberg. PMID- 27688812 TI - Imprinted DNA methylation reconstituted at a non-imprinted locus. AB - BACKGROUND: In mammals, tight regulation of cytosine methylation is required for embryonic development and cellular differentiation. The trans-acting DNA methyltransferases that catalyze this modification have been identified and characterized; however, these proteins lack sequence specificity, leaving the mechanism of targeting unknown. A cis-acting regulator within the Rasgrf1 imprinting control region (ICR) is necessary for establishment and maintenance of local imprinted methylation. Here, we investigate whether 3-kb of sequence from the Rasgrf1 ICR is sufficient to direct appropriate imprinted methylation and target gene expression patterns when ectopically inserted at the Wnt1 locus. RESULTS: The Rasgrf1 ICR at Wnt1 lacked somatic methylation when maternally transmitted and was fully methylated upon paternal transmission, consistent with its behavior at the Rasgrf1 locus. It was unmethylated in the female germline and was enriched for methylation in the male germline, though not to the levels seen at the endogenous Rasgrf1 allele. Wnt1 expression was not imprinted by the ectopic ICR, likely due to additional sequences being required for this function. CONCLUSIONS: We have identified sequences that are sufficient for partial establishment and full maintenance of the imprinted DNA methylation patterns. Because full somatic methylation can occur without full gametic methylation, we infer that somatic methylation of the Rasgrf1 ICR is not simply a consequence of maintained gametic methylation.

AB - The emerging enteric pathogen Campylobacter concisus is associated with prolonged diarrhea and inflammatory bowel disease. Previous studies have shown that C. concisus strains are very genetically diverse. Nevertheless, C. concisus strains have been divided into two genomospecies, where GS1 strains have been isolated predominantly from healthy individuals, while the GS2 cluster consists of isolates primarily from diarrheic individuals. The aim of the present study was to determine the genetic diversity of C. concisus isolates from Danish diarrheic patients. Multilocus sequence typing using the loci aspA, atpA, glnA, gltA, glyA, ilvD and pgm, as well as genomospecies based on specific differences in the 23S rRNA, was used to characterize 67 isolates (63 fecal and 4 oral), from 49 patients with different clinical presentations (29 with diarrhea, eight with bloody diarrhea, seven with collagenous colitis and five with Crohn's disease). MLST revealed a high diversity of C. concisus with 53 sequence types (STs), of which 52 were identified as 'new' STs. Allele sequences showed more than 90 % similarity between isolates, with only four outliers. Dendrogram profiles of each allele showed a division into two groups, which more or less correlated with genomospecies A and genomospecies B. However, in contrary to previous results, this subgrouping had no association to the clinical severity of disease. PMID- 27688813 TI - A survey exploring self-reported indoor and outdoor footwear habits, foot problems and fall status in people with stroke and Parkinson's. AB - BACKGROUND: Ill-fitting shoes have been implicated as a risk factor for falls but research to date has focused on people with arthritis, diabetes and the general older population; little is known about people with neurological conditions. This survey for people with stroke and Parkinson's explored people's choice of indoor and outdoor footwear, foot problems and fall history. METHODS: Following ethical approval, 1000 anonymous postal questionnaires were distributed to health professionals, leads of Parkinson's UK groups and stroke clubs in the wider Southampton area, UK. These collaborators handed out survey packs to people with a confirmed diagnosis of stroke or Parkinson's. RESULTS: Three hundred and sixty three completed surveys were returned (218 from people with Parkinson's and 145 from people with stroke). Most respondents wore slippers indoors and walking shoes outdoors and considered comfort and fit the most important factors when buying footwear. Foot problems were reported by 43 % (95 % confidence intervals 36 to 52 %; stroke) and 53 % (95 % confidence interval 46 to 59 %; Parkinson's) of respondents; over 50 % had never accessed foot care support. Fifty percent of all respondents reported falls. In comparison to non-fallers, a greater proportion of fallers reported foot problems (57 %), with greater proportions reporting problems impacting on balance and influencing choice of footwear (p < 0.01) in comparison to non-fallers in each case. Forty-seven percent of fallers with foot problems had not accessed foot care support. CONCLUSIONS: Many people with stroke and Parkinson's wear slippers indoors. A high percentage of these individuals reported both foot problems and falls impacting on footwear habits and choice of footwear; however many did not receive foot care support. These findings highlight that further exploration of footwear and foot problems in these populations is warranted to provide evidence based advice on safe and appropriate footwear to support rehabilitation and fall prevention. PMID- 27688816 TI - A Capillary Electrophoresis Electrospray Ionization-Mass Spectrometry Method using a Borate Background Electrolyte for the Fingerprinting Analysis of Flavonoids in Ginkgo biloba Herbal Supplements. AB - A laboratory-built sheath liquid capillary electrophoresis-mass spectrometry interface was used to develop a qualitative method for fingerprinting analysis of 14 structurally similar flavones, flavonols, flavonones, and several representative glycosides in plant samples. The migration order of the flavonoids was dependent on a the number of hydroxyl groups present on the flavonoid B-ring, extent of conjugation, number of glycosidic functionalities, and ability of the flavonoid to form stable borate complexes with the background electrolyte. Parent ion scans of the flavonoids yielded [M-H]-, except for catechol containing flavonoids, which were detected as borate adducts. These adducts can be used diagnostically to determine the presence or absence of catechol groups on unknown polyphenolic compounds. Product ion scans of the flavonoid glycosides and borate adducts typically yielded the deprotonated aglycone fragment as the base peak, which could be used to confirm the base structure of the flavonoid. This method's utility was demonstrated by analyzing flavonoids present in ethanolic extracts of Ginkgo biloba herbal supplements. PMID- 27688817 TI - MSP-HTPrimer: a high-throughput primer design tool to improve assay design for DNA methylation analysis in epigenetics. AB - BACKGROUND: Bisulfite (BS) conversion-based and methylation-sensitive restriction enzyme (MSRE)-based PCR methods have been the most commonly used techniques for locus-specific DNA methylation analysis. However, both methods have advantages and limitations. Thus, an integrated approach would be extremely useful to quantify the DNA methylation status successfully with great sensitivity and specificity. Designing specific and optimized primers for target regions is the most critical and challenging step in obtaining the adequate DNA methylation results using PCR-based methods. Currently, no integrated, optimized, and high throughput methylation-specific primer design software methods are available for both BS- and MSRE-based methods. Therefore an integrated, powerful, and easy-to use methylation-specific primer design pipeline with great accuracy and success rate will be very useful. RESULTS: We have developed a new web-based pipeline, called MSP-HTPrimer, to design primers pairs for MSP, BSP, pyrosequencing, COBRA, and MSRE assays on both genomic strands. First, our pipeline converts all target sequences into bisulfite-treated templates for both forward and reverse strand and designs all possible primer pairs, followed by filtering for single nucleotide polymorphisms (SNPs) and known repeat regions. Next, each primer pairs are annotated with the upstream and downstream RefSeq genes, CpG island, and cut sites (for COBRA and MSRE). Finally, MSP-HTPrimer selects specific primers from both strands based on custom and user-defined hierarchical selection criteria. MSP-HTPrimer produces a primer pair summary output table in TXT and HTML format for display and UCSC custom tracks for resulting primer pairs in GTF format. CONCLUSIONS: MSP-HTPrimer is an integrated, web-based, and high-throughput pipeline and has no limitation on the number and size of target sequences and designs MSP, BSP, pyrosequencing, COBRA, and MSRE assays. It is the only pipeline, which automatically designs primers on both genomic strands to increase the success rate. It is a standalone web-based pipeline, which is fully configured within a virtual machine and thus can be readily used without any configuration. We have experimentally validated primer pairs designed by our pipeline and shown a very high success rate of primer pairs: out of 66 BSP primer pairs, 63 were successfully validated without any further optimization step and using the same qPCR conditions. The MSP-HTPrimer pipeline is freely available from http://sourceforge.net/p/msp-htprimer. PMID- 27688818 TI - The emerging role of lysine methyltransferase SETD8 in human diseases. AB - SETD8/SET8/Pr-SET7/KMT5A is the only known lysine methyltransferase (KMT) that monomethylates lysine 20 of histone H4 (H4K20) in vivo. Lysine residues of non histone proteins including proliferating cell nuclear antigen (PCNA) and p53 are also monomethylated. As a consequence, the methyltransferase activity of the enzyme is implicated in many essential cellular processes including DNA replication, DNA damage response, transcription modulation, and cell cycle regulation. This review aims to provide an overview of the roles of SETD8 in physiological and pathological pathways and to discuss the progress made to date in inhibiting the activity of SETD8 by small molecules, with an emphasis on their discovery, selectivity over other methyltransferases and cellular activity. PMID- 27688820 TI - Interrelation of Glycemic Status and Neuropsychiatric Disturbances in Farmers with Organophosphorus Pesticide Toxicity. AB - BACKGROUND: Diverse group of agro-chemicals are indiscriminately sprayed by the farmers for pest control to enhance crop yield. About 25 million agricultural workers in the developing world suffer from at least one episode of poisoning each year, mainly by anticholinesterase- like organophosphates (OPs). OBJECTIVE: The present study was aimed to establish the OP toxicity in 187 occupationally exposed pesticide sprayers of mango plantation in rural Malihabad, Lucknow, in terms of neuro-cognitive impairment, mental health status, clinical symptoms, diabetes, and hematological factors. METHOD: The exposed group was compared to 187 pesticides-unexposed normal healthy persons engaged in normal usual agricultural work (age, sex and education corresponding to age group of selected subject group) from Rural Malihabad, Lucknow (India). Neuro-cognitive impairment was measured using the Subjective Neurocognition Inventory and mental health status using the General Health questionnaire-28. The subjects were also tested for biochemical and enzymatic parameters. RESULTS: The exposed farmers showed alterations in enzymatic and clinical parameters. While the rates of anxiety / insomnia and severe depression were also significantly higher in the pesticide sprayers, disorders affecting psychomotor speed, selective attention, divided attention, verbal memory, nonverbal memory, prospective memory, spatial functioning, and initiative/energy were all lower in the sprayers. Pesticide sprayers showed a number of clinical symptoms like eczema, saliva secretion, fatigue, headache, sweating, abdominal pain, nausea, superior distal muscle weakness, inferior distal muscle weakness, hand tingling and etc. which all significantly correlated with the number of working years. CONCLUSION: These findings suggested that farmers who work with OPs are prone to neuro psychological disorders and diabetes. PMID- 27688819 TI - DNA methylation and smoking in Korean adults: epigenome-wide association study. AB - BACKGROUND: Exposure to cigarette smoking can increase the risk of cancers and cardiovascular and pulmonary diseases. However, the underlying mechanisms of how smoking contributes to disease risks are not completely understood. Epigenome wide association studies (EWASs), mostly in non-Asian populations, have been conducted to identify smoking-associated methylation alterations at individual probes. There are few data on regional methylation changes in relation to smoking. Few data link differential methylation in blood to differential gene expression in lung tissue. RESULTS: We identified 108 significant (false discovery rate (FDR) < 0.05) differentially methylated probes (DMPs) and 87 significant differentially methylated regions (DMRs) (multiple-testing corrected p < 0.01) in current compared to never smokers from our EWAS of cotinine validated smoking in blood DNA from a Korean chronic obstructive pulmonary disease cohort (n = 100 including 31 current, 30 former, and 39 never smokers) using Illumina HumanMethylation450 BeadChip. Of the 108 DMPs (FDR < 0.05), nine CpGs were statistically significant based on Bonferroni correction and 93 were novel including five that mapped to loci previously associated with smoking. Of the 87 DMRs, 66 were mapped to novel loci. Methylation correlated with urine cotinine levels in current smokers at six DMPs, with pack-years in current smokers at six DMPs, and with duration of smoking cessation in former smokers at eight DMPs. Of the 143 genes to which our significant DMPs or DMRs annotated, gene expression levels at 20 genes were associated with pack-years in lung tissue transcriptome data of smokers (Asan Biobank, n = 188). CONCLUSIONS: Our study of differential methylation in Koreans confirmed previous findings from non-Asian populations and revealed novel loci in relation to smoking. Smoking-related differential methylation in blood is associated with gene expression in lung tissue, an important target of adverse health effects of smoking, supporting the potential functional importance of methylation in smoking-related disease. PMID- 27688821 TI - Structural and Optical Properties of Discrete Dendritic Pt Nanoparticles on Colloidal Au Nanoprisms. AB - Catalytic and optical properties can be coupled by combining different metals into nanoscale architectures in which both the shape and the composition provide fine-tuning of functionality. Here, discrete, small Pt nanoparticles (diameter = 3-6 nm) were grown in linear arrays on Au nanoprisms, and the resulting structures are shown to retain strong localized surface plasmon resonances. Multidimensional electron microscopy and spectroscopy techniques (energy dispersive X-ray spectroscopy, electron tomography, and electron energy-loss spectroscopy) were used to unravel their local composition, three-dimensional morphology, growth patterns, and optical properties. The composition and tomographic analyses disclose otherwise ambiguous details of the Pt-decorated Au nanoprisms, revealing that both pseudospherical protrusions and dendritic Pt nanoparticles grow on all faces of the nanoprisms (the faceted or occasionally twisted morphologies of which are also revealed), and shed light on the alignment of the Pt nanoparticles. The electron energy-loss spectroscopy investigations show that the Au nanoprisms support multiple localized surface plasmon resonances despite the presence of pendant Pt nanoparticles. The plasmonic fields at the surface of the nanoprisms indeed extend into the Pt nanoparticles, opening possibilities for combined optical and catalytic applications. These insights pave the way toward comprehensive nanoengineering of multifunctional bimetallic nanostructures, with potential applications in plasmon-enhanced catalysis and in situ monitoring of chemical processes via surface-enhanced spectroscopy. PMID- 27688822 TI - Engaging Communities in Research on Cumulative Risk and Social Stress-Environment Interactions: Lessons Learned from EPA's STAR Program. AB - Studies have documented cumulative health effects of chemical and nonchemical exposures, particularly chronic environmental and social stressors. Environmental justice groups have advocated for community participation in research that assesses how these interactions contribute to health disparities experienced by low-income and communities of color. In 2009, the U.S. Environmental Protection Agency issued a request for research applications (RFA), "Understanding the Role of Nonchemical Stressors and Developing Analytic Methods for Cumulative Risk Assessments." Seven research projects were funded to help address this knowledge gap. Each engaged with communities in different ways. We describe the community engagement approaches of the seven research projects, which ranged from outreach through shared leadership/participatory. We then assess the experiences of these programs with respect to the community engagement goals of the RFA. We present insights from these community engagement efforts, including how the grants helped to build or enhance the capacity of community organizations in addition to contributing to the research projects. Our analysis of project proposals, annual grantee reports, and participant observation of these seven projects suggests guidelines for the development of future funding mechanisms and for conducting community-engaged research on cumulative risk involving environmental and social stressors including: 1) providing for flexibility in the mode of community engagement; 2) addressing conflict between research timing and engagement needs, 3) developing approaches for communicating about the uniquely sensitive issues of nonchemical stressors and social risks; and 4) encouraging the evaluation of community engagement efforts.

PMID- 27688824 TI - Soluble Receptor for Advanced Glycation End Product Ameliorates Chronic Intermittent Hypoxia Induced Renal Injury, Inflammation, and Apoptosis via P38/JNK Signaling Pathways. AB - Obstructive sleep apnea (OSA) associated chronic kidney disease is mainly caused by chronic intermittent hypoxia (CIH) triggered tissue damage. Receptor for advanced glycation end product (RAGE) and its ligand high mobility group box 1 (HMGB1) are expressed on renal cells and mediate inflammatory responses in OSA related diseases. To determine their roles in CIH-induced renal injury, soluble RAGE (sRAGE), the RAGE neutralizing antibody, was intravenously administered in a CIH model. We also evaluated the effect of sRAGE on inflammation and apoptosis. Rats were divided into four groups: (1) normal air (NA), (2) CIH, (3) CIH+sRAGE, and (4) NA+sRAGE. Our results showed that CIH accelerated renal histological injury and upregulated RAGE-HMGB1 levels involving inflammatory (NF-kappaB, TNF alpha, and IL-6), apoptotic (Bcl-2/Bax), and mitogen-activated protein kinases (phosphorylation of P38, ERK, and JNK) signal transduction pathways, which were abolished by sRAGE but p-ERK. Furthermore, sRAGE ameliorated renal dysfunction by attenuating tubular endothelial apoptosis determined by immunofluorescence staining of CD31 and TUNEL. These findings suggested that RAGE-HMGB1 activated chronic inflammatory transduction cascades that contributed to the pathogenesis of the CIH-induced renal injury. Inhibition of RAGE ligand interaction by sRAGE provided a therapeutic potential for CIH-induced renal injury, inflammation, and apoptosis through P38 and JNK pathways. PMID- 27688825 TI - Rosmarinic Acid and Melissa officinalis Extracts Differently Affect Glioblastoma Cells. AB - Lemon balm (Melissa officinalis L.) has many biological effects but especially important is its neuroprotective activity. The aim of the study is to produce different extracts of Melissa officinalis and analyse their chemical composition and biological properties on rat glioblastoma C6 cells. Results revealed that rosmarinic acid (RA) is the predominant compound of lemon balm extracts. RA has cytotoxic effect on glioblastoma cells (LC50 290.5 MUM after the incubation of 24 h and LC50 171.3 MUM after 48 h). RA at concentration 80-130 MUM suppresses the cell proliferation and has an antioxidant effect. 200 MUM and higher concentrations of RA have a prooxidant effect and initiate cell death through necrosis. The aqueous extract of lemon balm is also enriched in phenolic compounds: protocatechuic, caftaric, caffeic, ferulic, and cichoric acids and flavonoid luteolin-7-glucoside. This extract at concentrations 50 MUM-200 MUM RA has cytotoxic activity and initiates cell death through apoptosis. Extracts prepared with 70% ethanol contain the biggest amount of active compounds. These extracts have the highest cytotoxic activity on glioblastoma cells. They initiate generation of intracellular ROS and cell death through apoptosis and necrosis. Our data suggest that differently prepared lemon balm extracts differently affect glioblastoma cells and can be used as neuroprotective agents in several therapeutic strategies. PMID- 27688826 TI - Altered Striatocerebellar Metabolism and Systemic Inflammation in Parkinson's Disease. AB - Parkinson's disease (PD) is the most second common neurodegenerative movement disorder. Neuroinflammation due to systemic inflammation and elevated oxidative stress is considered a major factor promoting the pathogenesis of PD, but the relationship of structural brain imaging parameters to clinical inflammatory markers has not been well studied. Our aim was to evaluate the association of magnetic resonance spectroscopy (MRS) measures with inflammatory markers. Blood samples were collected from 33 patients with newly diagnosed PD and 30 healthy volunteers. MRS data including levels of N-acetylaspartate (NAA), creatine (Cre), and choline (Cho) were measured in the bilateral basal ganglia and cerebellum. Inflammatory markers included plasma nuclear DNA, plasma mitochondrial DNA, and apoptotic leukocyte levels. The Cho/Cre ratio in the dominant basal ganglion, the dominant basal ganglia to cerebellum ratios of two MRS parameters NAA/Cre and Cho/Cre, and levels of nuclear DNA, mitochondrial DNA, and apoptotic leukocytes were significantly different between PD patients and normal healthy volunteers. Significant positive correlations were noted between MRS measures and inflammatory marker levels. In conclusion, patients with PD seem to have abnormal levels of inflammatory markers in the peripheral circulation and deficits in MRS measures in the dominant basal ganglion and cerebellum. PMID- 27688827 TI - Antioxidant and Vasodilator Activity of Ugni molinae Turcz. (Murtilla) and Its Modulatory Mechanism in Hypotensive Response. AB - Hypertension is a systemic condition with high morbidity and mortality rates worldwide, which poses an increased risk for cardiovascular diseases. In this study, we demonstrated the antioxidant and vasodilator activity of Ugni molinae Turcz. (Murtilla) fruit, a berry native to Chile and proposed models to explain its modulatory mechanism in hypotensive response. Murtilla fruits were cultivated in a germplasm bank and submitted to chemical and biological analyses. The phenolic compounds gallic acid, Catechin, Quercetin-3-beta-D-glucoside, Myricetin, Quercetin, and Kaempferol were identified. Murtilla extract did not generate toxic effects on human endothelial cells and had significant antioxidant activity against ROS production, lipid peroxidation, and superoxide anion production. Furthermore, it showed dose-dependent vasodilator activity in aortic rings in the presence of endothelium, whose hypotensive mechanism is partially mediated by nitric oxide synthase/guanylate cyclase and large-conductance calcium dependent potassium channels. Murtilla fruits might potentially have beneficial effects on the management of cardiovascular diseases.

PMID- 27688832 TI - Patient-Reported Outcomes in Oncology Drug Labeling in the United States: A Framework for Navigating Early Challenges. AB - BACKGROUND: Despite an increased use of patient-reported outcomes (PROs) in oncology clinical trials, integrating the patient perspective into drug approval decisions and documentation has been challenging. OBJECTIVES: To review important regulatory and measurement terminology, and to provide oncology outcomes researchers and those involved with building oncology programs with tools to plan PRO data collection, particularly in relation to drug efficacy claims for drug labeling in the United States. DISCUSSION: When contemplating a PRO measurement strategy for oncology clinical trials, outcomes researchers are challenged in several ways. First, given multiple stakeholders, researchers must communicate with their scientific, commercial, and regulatory colleagues using often misunderstood terms, such as "label," "claim," "end point," "outcome," and "concept." Second, because stakeholders do not always have access to data from early-stage clinical trials and do not contribute to the target drug's profile in early development, researchers are often unable to address the most important question in building a measurement strategy: What do we want to say about our drug? To overcome these challenges, researchers can systematically develop an end point model to facilitate communication among drug development stakeholders using a common language and to link the building blocks of a PRO measurement strategy, including claims, concepts, questionnaires, and end points. We developed a model that characterizes a disease by its proximal signs and/or symptoms and increasingly distal health outcomes to provide researchers potential measurement concepts that can be instrumental in selecting PRO questionnaires for use in studies. CONCLUSION: PRO data collected in clinical trials should be used in drug development to evaluate the drug's efficacy; it is encouraging that US regulators are willing to work with drug sponsors to overcome the challenges associated with the development, implementation, and interpretation of PROs. The tools discussed in this article can facilitate the planning process for oncology researchers, as well as assist in communicating with US regulators. PMID- 27688828 TI - Melatonin in Retinal Physiology and Pathology: The Case of Age-Related Macular Degeneration. AB - Melatonin, an indoleamine, is synthesized mainly in the pineal gland in a circadian fashion, but it is produced in many other organs, including the retina, which seems to be especially important as the eye is a primary recipient of circadian signals. Melatonin displays strong antioxidative properties, which predispose it to play a protective role in many human pathologies associated with oxidative stress, including premature aging and degenerative disease. Therefore, melatonin may play a role in age-related macular degeneration (AMD), a disease affecting photoreceptors, and retinal pigment epithelium (RPE) with an established role of oxidative stress in its pathogenesis. Several studies have shown that melatonin could exert the protective effect against damage to RPE cells evoked by reactive oxygen species (ROS), but it has also been reported to increase ROS-induced damage to photoreceptors and RPE. Melatonin behaves like synthetic mitochondria-targeted antioxidants, which concentrate in mitochondria at relatively high levels; thus, melatonin may prevent mitochondrial damage in AMD. The retina contains telomerase, an enzyme implicated in maintaining the length of telomeres, and oxidative stress inhibits telomere synthesis, while melatonin overcomes this effect. These features support considering melatonin as a preventive and therapeutic agent in the treatment of AMD.

OBJECTIVES: To identify treatment-related AEs in patients with metastatic melanoma and to estimate the associated costs of treating these AEs in the United States. METHODS: A cost-estimation study for AEs associated with treatment of metastatic melanoma was conducted from 2012 to 2013 by identifying grades 3 and 4 AEs through the use of a comprehensive search of drug labels and English-language, published phase 2/3 studies in PubMed, conference abstracts, and the National Comprehensive Cancer Network guidelines. Resource utilization for the management of each type of AE in the outpatient setting was obtained via interviews with 5 melanoma specialists in the United States. Unit costs for an AE associated with melanoma treatment in the outpatient setting were assigned using Medicare reimbursement rates to obtain these costs. Hospitalization and length-of-stay costs were estimated for each associated AE using the large national claims database Optum Clinformatics Data Mart for the period of July 1, 2004, to November 30, 2012. RESULTS: The most common AEs associated with chemotherapies used for melanoma were neutropenia, vomiting, and anemia. The most common AEs associated with vemurafenib were cutaneous squamous cell carcinoma or keratoacanthoma, rash, and elevated liver enzymes; the most common AEs associated with dabrafenib were cutaneous squamous-cell carcinoma and pyrexia. Trametinib was most often associated with hypertension and rash. The most common AEs with ipilimumab were immune-related diarrhea or colitis, dyspnea, anemia, vomiting, and, less frequently, hypophysitis. The most common grade 3/4 AE with talimogene laherparepvec was cellulitis. The highest treatment costs for an AE in the outpatient setting were for neutropenia ($2092), headache ($609), and peripheral neuropathy ($539). The highest mean inpatient costs for an AE were for acute myocardial infarction, sepsis, and coma, which ranged from $31,682 to $47,069. Colitis or diarrhea, cutaneous squamous-cell carcinoma, thrombocytopenia, hyponatremia, oliguria or anuria, hypertension, anemia, and elevated liver enzymes were associated with mean costs for hospitalization ranging from $19,122 to $26,861. CONCLUSION: The costs of managing treatment related AEs in patients with metastatic melanoma are substantial. Effective treatments with improved safety profiles may help to reduce these costs. Until real-world evidence for the costs associated with treatment toxicity is available in the outpatient and inpatient settings, the costs estimated in this study can help inform decision makers about the cost-effectiveness of managing patients with metastatic melanoma.

PMID- 27688834 TI - Thromboembolic Events Associated with Bevacizumab plus Chemotherapy for Patients with Colorectal Cancer: A Meta-Analysis of Randomized Controlled Trials. AB - BACKGROUND: Bevacizumab is a recombinant, humanized monoclonal antibody that hinders the proliferation of new blood vessels required for malignant progression. The drug is considered safe and tolerable; however, some controversy remains about whether it is linked to venous and arterial thromboembolic events (TEEs). OBJECTIVE: To evaluate the risk for overall, venous, and arterial TEEs in patients with colorectal cancer (CRC) who are administered bevacizumab plus chemotherapy in randomized controlled trials (RCTs). METHODS: We searched PubMed and CENTRAL databases to extract reports of relevant trials that were published in English between January 1, 2003, and December 31, 2014. All RCTs in which bevacizumab plus chemotherapy was compared with standard chemotherapy or with placebo plus chemotherapy for the treatment of CRC, and TEEs were reported, were included in a meta-analysis. Risk ratios (RRs) with 95% confidence intervals (CIs) of TEEs were calculated for each RCT. Because the between-study heterogeneities (I2) were insignificant, a fixed-effect model was used to determine the effect size of each TEE. A funnel plot was created to assess publication bias, and 2 forms of sensitivity analyses were performed for each outcome. RESULTS: This meta-analysis included 22 RCTs with a total of 13,185 patients. Overall, compared with the control groups, patients with CRC who received bevacizumab were at significant risk for overall TEEs (RR, 1.334; 95% CI, 1.191-1.494; P <.001; I2 = 1.37%). Regarding venous TEEs, a significant risk was observed for patients who received bevacizumab versus control patients (RR, 1.244; 95% CI, 1.091-1.415; P = .001; I2 = 0.0%). Similarly, the risk for arterial TEEs was significant in bevacizumab-treated patients (RR, 1.627; 95% CI, 1.162-2.279; P = .005; I2 = 0.0%). Sensitivity analyses did not affect the level of significance of the effect size for each outcome, and no significant publication bias was observed. CONCLUSION: In all the studies reviewed in this meta-analysis, the risk for venous or arterial TEEs was associated with bevacizumab use in patients with CRC. Healthcare providers are encouraged to consider thromboprophylaxis agents, periodically monitor their patients who receive bevacizumab, and carefully manage patients who are at increased risk for those complications. PMID- 27688837 TI - The First Study of Cartilage by Magnetic Resonance: A Historical Account. AB - OBJECTIVE: To recap the historical journey leading to the first cartilage research article using nuclear magnetic resonance (NMR), published in 1955 by 2 Swedish researchers, Erik Odeblad and Gunnar Lindstrom. DESIGN: Extensive Internet search utilizing both English and Swedish websites, and reading the dissertations available at the Royal Institute of Technology (Stockholm, Sweden) and via interlibrary loans at Oakland University (Michigan, USA). RESULTS: Using a primitive NMR instrument that Lindstrom built for his graduate research at the Nobel Institute for Physics (Stockholm, Sweden), Odeblad and Lindstrom studied the characteristics of the NMR signal in calf cartilage. The authors wrote, "In cartilage and fibrous tissue, in which the proton signals probably arise from highly viscous water with short spin-lattice relaxation time, the signals were also larger than would correspond to the water content." The authors speculated the signal differences between water and biological tissues could be attributed to the absorption and organization of the water molecules to the proteins in the tissue, which was remarkably accurate. CONCLUSIONS: It is quite certain that Odeblad and Lindstrom published the first biomedical study using NMR in 1955. In this article, cartilage and a number of other biological tissues were examined for the first time using NMR.

PMID- 27688839 TI - Matrix-Associated Autologous Chondrocyte Implantation: A Clinical Follow-Up at 15 Years. AB - INTRODUCTION: A prospective clinical investigation was carried out in order to clarify whether Matrix-associated autologous chondrocyte implantation (MACI) results in clinical improvement at long-term follow-up. HYPOTHESIS: MACI will result in clinical improvement at long-term follow-up. STUDY DESIGN: Case series; level of evidence, 4. METHODS: Thirty-eight patients were treated with MACI. These patients were evaluated for up to a mean of 16 years (range 15-17 years) after the intervention. Three different scores (Lysholm-Gilquist score, International Cartilage Repair Society score, and Tegner score) formed the basis of this study. Overall, we were able to obtain valid preoperative and postoperative results from 18 (47%) of 38 patients. In 1 patient, both knees were treated. In 4 patients, an arthroplasty was implanted over the course of time; thus they were excluded from this case series. In conclusion, follow-up of 15 knees was performed in the recent series. RESULTS: In subjective rating, 12 out of 14 patients (86%) rated the function of their knee as much better or better than before the index procedure. All numerical outcome scores showed significant improvement compared to the preoperative value (preoperative/postoperative at 5 years/postoperative at 15 years): Lysholm score 59.6 (+/-24.6)/78.6 (+/ 21.5)/82.7 (+/-11.3), International Knee Documentation Committee score 50.6 (+/ 22.7)/64.7 (+/-21.6)/69.7 (+/-18.7), Tegner score 3.0 (+/-2.2)/3.6 (+/-1.5)/5.2 (+/-1.7). CONCLUSION: The significantly improved results on 3 scores after 15 years suggest that MACI represents a suitable treatment of local cartilage defects in the knee. PMID- 27688838 TI - Long-Term Outcomes after Autologous Chondrocyte Implantation: A Systematic Review at Mean Follow-Up of 11.4 Years. AB - OBJECTIVE: Autologous chondrocyte implantation (ACI) has not been proven to be durable over the long-term. The purpose of this systematic review was (1) to evaluate activity level and knee function, (2) to evaluate reoperation and failure rates, and (3) to analyze risk factors for reoperation and failure of ACI at minimum long-term follow-up. DESIGN: A comprehensive review was performed for studies with long-term outcomes after ACI for cartilage defect repair. Studies reported outcome scores such as Tegner score, Lysholm score, and International Knee Documentation Society (IKDC) score along with rates of failure and reoperation. Modified Coleman Methodology Scores were calculated to assess study methodological quality. RESULTS: Nine studies with a total of 771 patients with a mean age of 33.4 +/- 2.5 years, mean defect size of 5.9 +/- 1.6 cm(2), and mean follow-up of 11.4 years were included. Tegner score, Lysholm score, and IKDC score change from preoperative to final follow-up was 1.1 (95% CI 0.8-1.4, P < 0.001), 24.9 points (95% CI 18.8-31, P < 0.001), and 16.5 points (95% CI 5.4 27.5, P < 0.01), respectively. The mean failure and reoperation rates were 18% and 37%, respectively. Increased age and lesion size (>4.5 cm(2)) were significantly correlated with increased risk of reoperation and failure. CONCLUSIONS: Overall, ACI demonstrated successful outcomes in 82% of patients over the long-term. Increased patient age and lesion size greater than 4.5 cm(2) were risk factors for a higher reoperation and failure rate. Nonetheless, this review is limited by heterogeneity in surgical technique, and lesion and patient characteristics. PMID- 27688840 TI - Acute Delamination of Commercially Available Decellularized Osteochondral Allograft Plugs: A Report of Two Cases. AB - Articular cartilage injuries, and corresponding surgical procedures, are occurring with increasing frequency as identified by a review of recent surgical trends. Concerns have grown in recent years regarding the longevity of results following microfracture, with a shift toward cartilage restoration procedures in recent years. This case report describes 2 cases of acute failure following the use of commercially available osteochondral allograft plugs used for the treatment of osteochondral defects of the distal femur. In both cases the chondral surface of the plug delaminated from the underlying cancellous bone, resulting in persistent pain and swelling requiring reoperation and removal of the loose fragments. Caution should be employed when considering use of these plugs for the treatment of osteochondral lesions, as similar outcomes have not been noted with other cartilage restoration techniques. PMID- 27688841 TI - Safety of Repeated Injections of Sodium Hyaluronate (SUPARTZ) for Knee Osteoarthritis: A Systematic Review and Meta-Analysis. AB - OBJECTIVE: Though there is no consensus on its efficacy, knee osteoarthritis is symptomatically managed with intra-articular hyaluronic acid (IAHA). Recent reports suggest that IAHA may delay the need for total knee replacement, with the magnitude of delay proportional to the number of injection series. However, the safety of repeated injection series is reported to vary between commercial products. This report describes a systematic review of safety data on repeated treatment courses of SUPARTZ. DESIGN: We performed a systematic search of MEDLINE, Cochrane database, EMBASE, Web of Science, Google Scholar, and unpublished data. We included all human randomized controlled trials or observational studies with adverse event (AE) data for SUPARTZ in knee osteoarthritis. Two independent reviewers extracted data and evaluated study quality. Data were analyzed separately for the first and subsequent series of injections. RESULTS: The primary sources for repeated-injection data on SUPARTZ were a postmarket registry (N = 7404), 4 prospective studies (N = 127 total), and a retrospective study (N = 220). None of the sources reported increased frequency or severity of AEs with repeated injections. In the registry, 95% of multiple injection-series patients who reported an AE did so during the first series. None of the AEs was serious, and most resolved spontaneously without medical intervention. The overall adverse event rate after repeat courses of SUPARTZ was 0.008 (95% confidence interval: 0.001-0.055). CONCLUSIONS: Multiple courses of SUPARTZ injections appear to be at least as safe, and probably safer, than the first course. This study supports the safety of repeat courses of SUPARTZ injections for knee osteoarthritis. PMID- 27688842 TI - Expression of TGF-beta Signaling Regulator RBPMS (RNA-Binding Protein With Multiple Splicing) Is Regulated by IL-1beta and TGF-beta Superfamily Members, and Decreased in Aged and Osteoarthritic Cartilage. AB - OBJECTIVE: RNA-binding protein with multiple splicing (RBPMS) has been shown to physically interact with Smads and enhance transforming growth factor-beta (TGF beta)-mediated Smad2/3 transcriptional activity in mammalian cells. Objective of this study was to examine whether expression of RBPMS is regulated by interleukin 1beta (IL)-1beta and TGF-beta superfamily growth factors and whether expression of RBPMS is altered during aging and experimental osteoarthritis. METHODS: Expression of RBPMS protein was investigated in chondrocyte cell lines of murine (H4) and human (G6) origin using Western blot analysis. Regulation of RBPMS expression in H4 chondrocytes at mRNA level was done by reverse transcriptase quantitative polymerase chain reaction. Furthermore, characterization of Smad signaling pathways regulating RBPMS expression was performed by blocking studies using small molecule inhibitors or by transfection studies with adenoviral vector constructs (constitutive-active ALK1 and constitutive-active ALK5). Expression of RBPMS in cartilage of different age groups of C57BL/6N mice (6 months and 20 months) and in a surgically induced osteoarthritis (OA) mouse model was analyzed using immunohistochemistry. RESULTS: RBPMS was shown to be expressed in chondrocytes and cartilage of murine, human, and bovine origin. TGF-beta inhibited RBPMS expression while BMP2 and IL-1beta increased its expression. TGF beta-induced inhibition was blocked by ALK5 inhibitor. Overexpression of ca-ALK1 stimulated RBPMS expression. Moreover, RBPMS expression was found to be reduced with ageing and in OA pathogenesis. CONCLUSIONS: Expression of RBPMS in chondrocytes is regulated by TGF-beta superfamily members and IL-1beta, indicating a counter-regulatory mechanism. Expression of RBPMS, in cartilage and its reduction during ageing and OA might suggest its potential role in the maintenance of normal articular cartilage. PMID- 27688843 TI - Bilayer Implants: Electromechanical Assessment of Regenerated Articular Cartilage in a Sheep Model. AB - OBJECTIVE: To compare the regenerative capacity of 2 distinct bilayer implants for the restoration of osteochondral defects in a preliminary sheep model. METHODS: Critical sized osteochondral defects were treated with a novel biomimetic poly-epsilon-caprolactone (PCL) implant (Treatment No. 2; n = 6) or a combination of Chondro-Gide and Orthoss (Treatment No. 1; n = 6). At 19 months postoperation, repair tissue (n = 5 each) was analyzed for histology and biochemistry. Electromechanical mappings (Arthro-BST) were performed ex vivo. RESULTS: Histological scores, electromechanical quantitative parameter values, dsDNA and sGAG contents measured at the repair sites were statistically lower than those obtained from the contralateral surfaces. Electromechanical mappings and higher dsDNA and sGAG/weight levels indicated better regeneration for Treatment No. 1. However, these differences were not significant. For both treatments, Arthro-BST revealed early signs of degeneration of the cartilage surrounding the repair site. The International Cartilage Repair Society II histological scores of the repair tissue were significantly higher for Treatment No. 1 (10.3 +/- 0.38 SE) compared to Treatment No. 2 (8.7 +/- 0.45 SE). The parameters cell morphology and vascularization scored highest whereas tidemark formation scored the lowest. CONCLUSION: There was cell infiltration and regeneration of bone and cartilage. However, repair was incomplete and fibrocartilaginous. There were no significant differences in the quality of regeneration between the treatments except in some histological scoring categories. The results from Arthro-BST measurements were comparable to traditional invasive/destructive methods of measuring quality of cartilage repair. PMID- 27688844 TI - Transplantation of Scaffold-Free Cartilage-Like Cell-Sheets Made from Human Bone Marrow Mesenchymal Stem Cells for Cartilage Repair: A Preclinical Study. AB - OBJECTIVE: The object of this study was to determine culture conditions that create stable scaffold-free cartilage-like cell-sheets from human bone marrow derived mesenchymal stem cells (hBMSCs) and to assess their effects after transplantation into osteochondral defects in nude rats. DESIGN: (Experiment 1) The hBMSCs were harvested from 3 males, the proliferative and chondrogenic capacities were assessed at passage 1, and the cells were expanded in 3 different culture conditions: (1) 5% fetal bovine serum (FBS), (2) 10% FBS, and (3) 5% FBS with fibroblast growth factor 2 (FGF-2). The cells were harvested and made chondrogenic pellet culture. The cell proliferation rate, glycosaminoglycan/DNA ratio, and safranin-O staining intensity of pellets cultured condition 3 were higher than those of conditions 1 and 2. (Experiment 2) The hBMSCs were expanded and passaged 3 times under culture condition 3, and fabricate the cell-sheets in chondrogenic medium either with or without FBS. The cell-sheets fabricated with FBS maintained their size with flat edges. (Experiment 3) The cell-sheets were transplanted into osteochondral defects in nude rats. Histological analysis was performed at 2, 4, and 12 weeks after surgery. RESULTS: The osteochondral repair was better after sheet transplantation than in the control group and significantly improved Wakitani score. Immunostaining with human-specific vimentin antibody showed that the transplanted cells became fewer and disappeared at 12 weeks. CONCLUSIONS: These results indicate that culture with FGF-2 may help to quickly generate sufficient numbers of cells to create stable and reliable scaffold-free cartilage-like cell-sheets, which contribute to the regeneration of osteochondral defects. PMID- 27688847 TI - Counting with Colours? Effect of Colours on the Numerical Abilities of House Crows (Corvus splendens) and Common Myna (Acridotheres tristis). AB - We conducted several aviary experiments to investigate the influence of colours in quantity judgments of two species of birds; house crow (Corvus splendens) and common myna (Acridotheres tristis). Different quantity (in seven different food proportions) of mealworms were presented nonsequentially to all birds using artificially coloured red mealworms, for experiment 1, and using artificially coloured green mealworms, for experiment 2. Both red and green coloured mealworms have no significant effect on house crow's quantity judgments (red: ANOVA: F6,30 = 1.748, p = 0.144; and green: ANOVA: F6,30= 1.085, p = 0.394). Common myna, however, showed a strong influence of red colour in their quantity judgment ( ANOVA: F6,30 = 2.922, p = 0.023) as they succeeded in choosing the largest amount of food between two cups, but not when offered food using green coloured mealworms ( ANOVA: F6,30 = 1.183, p = 0.342). In the next experiment, we hypothesised that both house crow and common myna will prefer red coloured food items over green coloured food items, when factors such as the amount of food is equal. We chose to test red and green colours because both colours play an important role in most avian food selections. Results showed that there were no significant differences in the selection of red or green coloured mealworms for both house crows ( ANOVA: F6,30 = 2.310, p = 0.06) and common myna ( ANOVA: F6,30 = 0.823, p = 0.561). PMID- 27688846 TI - Modulation of Superficial Zone Protein/Lubricin/PRG4 by Kartogenin and Transforming Growth Factor-beta1 in Surface Zone Chondrocytes in Bovine Articular Cartilage. AB - OBJECTIVE: Superficial zone protein (SZP)/lubricin/PRG4 functions as a boundary lubricant in articular cartilage to decrease friction and wear. As articular cartilage lubrication is critical for normal joint function, the accumulation of SZP at the surface of cartilage is important for joint homeostasis. Recently, a heterocyclic compound called kartogenin (KGN) was found to induce chondrogenic differentiation and enhance mRNA expression of lubricin. The objective of this study was to determine whether KGN can stimulate synthesis of SZP in superficial zone, articular chondrocytes. DESIGN: We investigated the effects of KGN and transforming growth factor-beta1 (TGF-beta1) on articular cartilage and synovium of the bovine knee joint by evaluating SZP secretion by enzyme-linked immunosorbent assay analysis. Monolayer, micromass, and explant cultures of articular cartilage, and monolayer culture of synoviocytes, were treated with KGN. SZP accumulation in the medium was evaluated and mRNA expression was measured through quantitative polymerase chain reaction. RESULTS: TGF-beta1 stimulated SZP secretion by superficial zone chondrocytes in monolayer, explant, and micromass cultures as expected. In addition, SZP secretion was inhibited by IL-1beta in explant cultures, and enhanced by TGF-beta1 in synoviocyte monolayer cultures. Although KGN elicited a 1.2-fold increase in SZP mRNA expression in combination with TGF-beta1, KGN neither stimulated any significant increases in SZP synthesis nor prevented catabolic decreases in SZP production from IL-1beta. CONCLUSIONS: These data suggest that the chondrogenic effects of KGN depend on cellular phenotype and differentiation status, as KGN did not alter SZP synthesis in differentiated, superficial zone articular chondrocytes. PMID- 27688845 TI - The Chondroprotective Role of Erythromycin in a Murine Joint Destruction Model. AB - OBJECTIVE: Inflammation is a major player in the joint destruction process. Macrolide antibiotics have recently been found to have a novel anti-inflammatory function, but their effects on the joint are unknown. Our objective was to investigate the effect of macrolide antibiotic erythromycin on cartilage gene expression under inflammatory conditions as well as on joint pathology in an in vivo inflammatory joint destruction model. DESIGN: In our in vivo studies, mouse knee joints were injected with monosodium iodoacetate (MIA), a chemical that inhibits glycolysis and causes joint inflammation and matrix loss. Erythromycin was administered by daily intraperitoneal injection. Changes in joint cartilage and synovium were evaluated by histological analysis. In our in vitro studies, primary bovine articular chondrocytes were treated with erythromycin in the presence of pro-inflammatory cytokine IL-1beta or lipopolysaccharide (LPS), and cartilage gene expression analysis was performed. RESULTS: Regional differences in cartilage matrix destruction along the medial-lateral axis were observed in joints of MIA-injected mice. Erythromycin treatment inhibited cartilage matrix loss and synovitis in these joints. In addition, erythromycin inhibited IL-1beta and LPS-induced expression of MMPs and iNOS, as well as the positive regulatory loop between IL-1beta and Toll-like receptor 4 (TLR4) in articular chondrocytes. Furthermore, erythromycin prevented LPS-induced NF-kappaB activation, a key mediator of TLR4-mediated cartilage destruction process. CONCLUSIONS: Erythromycin has the ability to inhibit catabolic gene expression mediated by IL 1beta and TLR4 in chondrocytes in vitro and maintains cartilage matrix levels in experimental inflammatory joint destruction in vivo, suggesting that it possesses a chondroprotective activity. PMID- 27688848 TI - Current Status of the Milky Stork Re-introduction Programme in Malaysia and Its Challenges. AB - This review discussed the current status of the Milky Stork Re-introduction Programme in Malaysia and the challenges it faced. Although it has continued for almost seven years, more challenges appeared as time elapsed mainly due to the arising conflicts between the implementation of conservation policy versus the development projects in Kuala Gula. Hence, the released population is struggling to adapt mainly due to the reduction of suitable habitat for nesting and disturbed foraging areas by the continuous anthropogenic activities. Furthermore, the lack of appropriate training among captive storks prior to being released also slows the adaptation of the birds in their new habitat. The increasing pattern of pollution in the area is also highlighted. Several suggestions were given to help improve the current re-introduction programme. These include improvements to the captive training method, improvement of the existing enclosure's condition and environment, protection of remaining mangrove forest, creation of a buffer zone to mitigate the increasing pollution level in the area, close monitoring of the released population, and maintaining continuous support and awareness among the public. Considering the ongoing anthropogenic activities that may impair the status of Kuala Gula as an important bird sanctuary, emphasis should be given to achieve sustainable development throughout the area. PMID- 27688849 TI - Toxicity of Chlorophyllin against Lymnaea acuminata at Different Wavelengths of Visible Light. AB - Fasciolosis is a water and food-borne disease caused by the liver fluke Fasciola hepatica and Fasciola gigantica. This disease is widespread in different parts of the world. Lymnaeidae and Planorbidae snails are the intermediate hosts of these flukes. Snail population management is a good tool to control fasciolosis because gastropods represent the weakest link in the life-cycle of trematodes. Chlorophyll can be extracted from any green plant. Chlorophyllin was prepared from spinach in 100% ethanol by using different types of chemicals. The chlorophyll obtained from spinach was transformed into water-soluble chlorophyllin. In the present paper, toxicity of chlorophyllin against the snail Lymnaea acuminata was time and concentration dependent. The toxicity of extracted and pure chlorophyllin at continuous 4 h exposure of sunlight was highest with lethal concentration (LC50) of 331.01 mg/L and 2.60 mg/L, respectively, than discontinuous exposure of sunlight up to 8 h with LC50 of 357.04 mg/L and 4.94 mg/L, respectively. Toxicity of extracted chlorophyllin was noted in the presence of different monochromatic visible lights. The highest toxicity was noted in yellow light (96 h, LC50 392.77 mg/L) and the lowest in green light (96 h, LC50 833.02 mg/L). Chlorophyllin in combination with solar radiation or different wavelength of monochromatic visible lights may become a latent remedy against the snail L. acuminata. It was demonstrated that chlorophyllin was more toxic in sunlight. Chlorophyllin is ecologically safe and more economical than synthetic molluscicides which have the potential to control the incidence of fasciolosis in developing countries.

AB - The biochemical changes in two Selaginella species namely, S. tamariscina (Beauv.) Spring and S. plana (Desv. ex Poir.) Heiron., as induced by desiccation and subsequent rehydration were explored. Plants were allowed to dehydrate naturally by withholding irrigation until shoot's relative water content (RWC) reached <10%. After which, dehydrated plants were watered until fully rehydrated states were obtained which was about 90% RWC or more. Desiccation-tolerance characteristics were observed in S. tamariscina while desiccation-sensitivity features were seen in S. plana. Membrane integrity was maintained in S. tamariscina but not in S. plana as evidenced in the relative electrolyte leakage measurements during desiccation phase and the subsequent rehydration stage. Pigment analyses revealed conservation of some chlorophylls and carotenoids during desiccation and reaching control levels following rehydration in S. tamariscina. Very low pigment contents were found in S. plana during desiccation phase and the pigments were not recovered during rehydration attempt. Meanwhile, compatible solute determination showed rise in total sugar and proline contents of desiccated S. tamariscina only, indicating presence of biochemical protection machineries in this species and absence of such in S. plana during dehydrating conditions. These data indicate that one key element for desiccation-tolerance in lower vascular plants is the ability to protect tissues from severe damages caused by intense desiccation. PMID- 27688851 TI - Anti-malarial Activities of Two Soil Actinomycete Isolates from Sabah via Inhibition of Glycogen Synthase Kinase 3beta. AB - Exploiting natural resources for bioactive compounds is an attractive drug discovery strategy in search for new anti-malarial drugs with novel modes of action. Initial screening efforts in our laboratory revealed two preparations of soil-derived actinomycetes (H11809 and FH025) with potent anti-malarial activities. Both crude extracts showed glycogen synthase kinase 3beta (GSK3beta) inhibitory activities in a yeast-based kinase assay. We have previously shown that the GSK3 inhibitor, lithium chloride (LiCl), was able to suppress parasitaemia development in a rodent model of malarial infection. The present study aims to evaluate whether anti-malarial activities of H11809 and FH025 involve the inhibition of GSK3beta. The acetone crude extracts of H11809 and FH025 each exerted strong inhibition on the growth of Plasmodium falciparum 3D7 in vitro with 50% inhibitory concentration (IC50) values of 0.57 +/- 0.09 and 1.28 +/- 0.11 ug/mL, respectively. The tested extracts exhibited Selectivity Index (SI) values exceeding 10 for the 3D7 strain. Both H11809 and FH025 showed dosage-dependent chemo-suppressive activities in vivo and improved animal survivability compared to non-treated infected mice. Western analysis revealed increased phosphorylation of serine (Ser 9) GSK3beta (by 6.79 to 6.83-fold) in liver samples from infected mice treated with H11809 or FH025 compared to samples from non-infected or non-treated infected mice. A compound already identified in H11809 (data not shown), dibutyl phthalate (DBP) showed active anti-plasmodial activity against 3D7 (IC50 4.87 +/- 1.26 ug/mL which is equivalent to 17.50 uM) and good chemo-suppressive activity in vivo (60.80% chemo-suppression at 300 mg/kg body weight [bw] dosage). DBP administration also resulted in increased phosphorylation of Ser 9 GSK3beta compared to controls. Findings from the present study demonstrate that the potent anti-malarial activities of H11809 and FH025 were mediated via inhibition of host GSK3beta. In addition, our study suggests that DBP is in part the bioactive component contributing to the anti-malarial activity displayed by H11809 acting through the inhibition of GSK3beta. PMID- 27688852 TI - Beneficial Properties of Probiotics. AB - Probiotics are live microorganisms that can be found in fermented foods and cultured milk, and are widely used for the preparation of infant food. They are well-known as "health friendly bacteria", which exhibit various health beneficial properties such as prevention of bowel diseases, improving the immune system, for lactose intolerance and intestinal microbial balance, exhibiting antihypercholesterolemic and antihypertensive effects, alleviation of postmenopausal disorders, and reducing traveller's diarrhoea. Recent studies have also been focused on their uses in treating skin and oral diseases. In addition to that, modulation of the gut-brain by probiotics has been suggested as a novel therapeutic solution for anxiety and depression. Thus, this review discusses on the current probiotics-based products in Malaysia, criteria for selection of probiotics, and evidences obtained from past studies on how probiotics have been used in preventing intestinal disorders via improving the immune system, acting as an antihypercholesterolemic factor, improving oral and dermal health, and performing as anti-anxiety and anti-depressive agents.

AB - The interaction between plants and insects is dynamic, and may favour either the plant or the insect. Plant chemicals are deeply implicated in this relationship and influence insect behaviour. Here, we investigated the oviposition behaviour response of Culex quinquefasciatus mosquitoes based on the colour cues produced by Ipomoea cairica leaves extract. In this study, two sets of oviposition choice experiments were conducted: (1) single solution in a cage; and (2) multiple concentration solutions in a cage. In the single solution experiment, only 1 available oviposition site was offered to 5 gravid females and in the multiple concentration tests, 4 available oviposition sites were offered to 20 gravid females. The tested concentrations were set up at 100 mL of: (1) control (distilled water only); (2) 50 ppm; (3) 150 ppm; and (4) 300 ppm of I. cairica plant extracts. The highest concentration of 300 ppm appeared to show the highest intensity with the darkest colour followed by 150 ppm and 50 ppm concentrations. More gravid females were found drowned in the highest concentration, 300 ppm of acethonilic leaves extract, compared to 150 ppm and 50 ppm of the tested extract. No eggs were found in all tested solutions. The studied extract was found to effectively attract gravid Cx. quinquefasciatus females and subsequently cause mortality and inhibit egg deposition. The interference caused by the acethonilic extract of I. cairica on the oviposition activity of Cx. quinquefasciatus can result in better control of the vector insect.

AB - Five new records of terrestrial and lithophytic orchid species were gathered from Penang Hill, Pulau Pinang, Malaysia namely Bulbophyllum depressum, Goodyera pusilla, Peristylus monticola, Podochilus microphyllus, and Zeuxine gracilis. Checklist of each species is provided and their distribution in Penang Hill is discussed. PMID- 27688855 TI - Dietary Prebiotics and Probiotics Influence the Growth Performance, Feed Utilisation, and Body Indices of Snakehead (Channa striata) Fingerlings. AB - This study used a two-phase feeding trial to determine the influence of selected dietary prebiotics and probiotics on growth performance, feed utilisation, and morphological changes in snakehead (Channa striata) fingerlings as well as the duration of these effects over a post-experimental period without supplementation. Triplicate groups of fish (22.46 +/-0.17 g) were raised on six different treatment diets: three prebiotics (0.2% beta-glucan, 1% galacto oligosaccharides [GOS], 0.5% mannan-oligosaccharides [MOS]), two probiotics (1% live yeast [Saccharomyces cerevisiae] and 0.01% Lactobacillus acidophilus [LBA] powder) and a control (unsupplemented) diet; there were three replicates for each treatment. All diets contained 40% crude protein and 12% crude lipid. Fish were fed to satiation three times daily. No mortalities were recorded during Phase 1; however, 14% mortality was documented in the control and prebiotic-amended fish during Phase 2. At the end of Phase 1, growth performance and feed utilisation were significantly higher (p<0.05) in the LBA-treated fish, followed by live yeast treatment, compared with all other diets tested. The performance of fish on the three prebiotic diets were not significantly different from one another but was significantly higher than the control diet. During Phase 2 (the post-feeding phase), fish growth continued until the 6th week for the probiotic-based diets but levelled off after four weeks for the fish fed the prebiotic diets. The feed conversion ratio (FCR) was higher in all treatments during the post-feeding period. The hepatosomatic index (HSI) did not differ significantly among the tested diets. The visceral somatic index (VSI) and intraperitoneal fat (IPF) were highest in the LBA-based diet and the control diet, respectively. The body indices were significantly different (p<0.05) between Phases 1 and 2. This study demonstrates that probiotic-based diets have a more positive influence on the growth, feed utilisation, and survival of C. striata fingerlings compared with supplementation with prebiotics.

AB - The house sparrow (Passer domesticus) is a widely distributed bird species found throughout the world. Being a species which has close association with humans, they chiefly nest on man-made structures. Here we describe the materials used by the house sparrow for making nests along an urban to rural gradient. For the current study, we selected the Coimbatore to Anaikatty road (State Highway-164), a 27 km inter-state highway, which traverses along an urban core to rural outstretch of Coimbatore. Of the 30 nests observed, 15 nests were from the rural, 8 were from the suburban, and 7 were from the urban areas. The nests had two distinct layers, specifically the structural layer and the inner lining. In the current study, we identified 11 plant species, 2 types of animal matter, and 6 types of anthropogenic matter, including plastic pieces and fine rope. The amount of anthropogenic materials in the nest formation varied along the gradients. The usage of anthropogenic materials was high in urban areas (p<0.05) whereas it did not differ at the sub-urban regions (p>0.05). A gradual decrease in the usage of plant matter towards the urban area was noticed (p<0.05). This study explicitly documents the links between nest material usage along an urban to rural gradient, in a human associated bird. PMID- 27688857 TI - Socioeconomic Disparities in Cancer Screening: Organized versus Opportunistic. PMID- 27688858 TI - Is It Possible to Delay or Prevent Age-Related Cognitive Decline? AB - Already in the 90s, Khachaturian stated that postponing dementia onset by five years would decrease the prevalence of the late onset dementia by 50%. After two decades of lack of success in dementia drug discovery and development, and knowing that worldwide, currently 36 million patients have been diagnosed with Alzheimer's disease, a number that will double by 2030 and triple by 2050, the World Health Organization and the Alzheimer's Disease International declared that prevention of cognitive decline was a 'public health priority.' Numerous longitudinal studies and meta-analyses were conducted to analyze the risk and protective factors for dementia. Among the 93 identified risk factors, seven major modifiable ones should be considered: low education, sedentary lifestyle, midlife obesity, midlife smoking, hypertension, diabetes, and midlife depression. Three other important modifiable risk factors should also be added to this list: midlife hypercholesterolemia, late life atrial fibrillation, and chronic kidney disease. After their identification, numerous authors attempted to establish dementia risk scores; however, the proposed values were not convincing. Identifying the possible interventions, able to either postpone or delay dementia has been an important challenge. Observational studies focused on a single life style intervention increased the global optimism concerning these possibilities. However, a recent extensive literature review of the randomized control trials (RCTs) conducted before 2014 yielded negative results. The first results of RCTs of multimodal interventions (Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability, Multidomain Alzheimer Prevention Study, and Prediva) brought more optimism. Lastly, interventions targeting compounds of beta amyloid started in 2012 and no results have yet been published. PMID- 27688859 TI - The Relationship between the Blood Level of Persistent Organic Pollutants and Common Gastrointestinal Symptoms. AB - BACKGROUND: Persistent organic pollutants (POPs) are toxic materials that cannot be broken down naturally and that easily accumulate in the body. Although several studies have attempted to reveal the effects of POPs on the endocrine and nervous system and on cancer, few studies focus on the relationship between low-dose POPs and public health. We attempted to find a relationship between the level of POPs and common gastrointestinal symptoms, including abdominal discomfort, diarrhea, and constipation. METHODS: We recruited 121 subjects who visited Kyungpook National University Hospital for a health screening. Plasma concentrations were evaluated for 40 kinds of POPs including 17 types of polychlorinated biphenyls and 23 types of organochlorine pesticides. Furthermore, the Korean version of the Rome III criteria was used to identify gastrointestinal symptoms. RESULTS: Our results showed that abdominal discomfort had an inverse relationship with several polychlorinated biphenyls. Moreover, an inverted U-shaped relationship was observed between abdominal discomfort and several other organochlorine pesticides including p,p'-dichlorodiphenyldichloroethane and p,p' dichlorodiphenyltrichloroethane, and the effects of these pesticides on abdominal discomfort were similar to that of organochlorine pesticides on obesity and metabolic syndrome. CONCLUSION: Our results suggest that mild and unspecified gastrointestinal symptoms with no clear cause could be related to POPs levels. PMID- 27688860 TI - Relationship between Blood Mercury Concentration and Bone Mineral Density in Korean Men in the 2008-2010 Korean National Health and Nutrition Examination Survey. AB - BACKGROUND: The results of previous studies on the association between blood mercury (Hg) and bone mineral density (BMD) are inconsistent. We therefore used a large-scale nationwide representative sample of Korean men to investigate the relationship between these two parameters. METHODS: A nationwide cross-sectional study was conducted using data from the 2008 to 2010 Korean National Health and Nutrition Examination Survey to evaluate the relationship between blood Hg and BMD and the prevalence of osteopenia or osteoporosis in 1,190 men over 50 years of age. BMD was measured by dual-energy X-ray absorptiometry. Osteopenia and osteoporosis were diagnosed for each body site according to World Health Organization T-score criteria. RESULTS: After adjusting for age, body mass index, caloric energy and calcium intake, vitamin D levels, fish consumption, alcohol consumption, smoking, and exercise, quartiles of blood Hg were positively associated with femur neck T-scores in multiple linear regression analysis (beta=0.06, P-value=0.03). Compared with the lowest blood Hg quartile, the odds ratios and 95% confidence intervals for diagnosis of osteopenia or osteoporosis in the second and fourth quartiles were 0.63 (0.41-0.99) and 0.57 (0.36-0.91), respectively, in the femur neck after adjusting for the same co-variables. CONCLUSION: High blood Hg levels were associated with reduced odds of decreased femur neck BMD in Korean men. However, subgroup analysis did not show a significant protective effect of blood Hg on osteoporotic fractures. Further research is necessary to clarify the association between blood Hg and BMD. PMID- 27688861 TI - Association between Physical Activity Levels and Physical Symptoms or Illness among University Students in Korea. AB - BACKGROUND: Low levels of physical activity can cause various physical symptoms or illness. However, few studies on this association have been conducted in young adults. The aim of this study was to investigate the association between physical activity levels and physical symptoms or illness in young adults. METHODS: Subjects were university students who participated in a web-based self administered questionnaire in a university in Seoul in 2013. We obtained information on physical activities and physical symptoms or illness in the past year. Independent variables were defined as symptoms or illness which were associated with decreased academic performance. Logistic regression was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs) of each physical symptom or illness with adjustment for covariables. RESULTS: A total of 2,201 participants were included in the study. The main physical symptoms or illness among participants were severe fatigue (64.2%), muscle or joint pain (46.3%), gastrointestinal problems (43.1%), headache or dizziness (38.6%), frequent colds (35.1%), and sleep problems (33.3%). Low physical activity levels were significantly associated with high ORs of physical symptoms or illness. Multivariable-adjusted ORs (95% CIs) in the lowest vs. highest tertile of physical activity were 1.45 (1.14-1.83) for severe fatigue, 1.35 (1.07-1.70) for frequent colds, and 1.29 (1.02-1.63) for headaches or dizziness. We also found that lower levels of physical activity were associated with more physical symptoms or bouts of illness. CONCLUSION: Low physical activity levels were significantly associated with various physical symptoms or illness among university students. Also, individuals in the lower levels of physical activity were more likely to experience more physical symptoms or bouts of illness than those in the highest tertile of physical activity. PMID- 27688862 TI - Association between Socioeconomic Status and Cancer Screening in Koreans over 40 Years in Age Based on the 2010-2012 Korean National Health and Nutrition Examination Survey. AB - BACKGROUND: We investigated the association between socioeconomic status (SES) and cancer screening in a Korean population aged 40 years or older. METHODS: This cross-sectional study included 12,303 participants (5,284 men and 7,019 women) who participated in the 2010-2012 Korean National Health and Nutrition Examination Survey. Self-reported questionnaires were used to assess participant's SES (household income, occupational, and educational status) and cancer screening behavior. RESULTS: Compared to the lowest household income group, the odds ratios (ORs) (95% confidence intervals [CIs]) for overall cancer screening of the highest income group were 2.113 (1.606-2.781) in men and 1.476 (1.157-1.883) in women; those for private cancer screening of the highest income group were 2.446 (1.800-3.324) in men and 2.630 (2.050-3.373) in women, while those for National Cancer Screening Programs (NCSP) in the highest income group were 1.076 (0.805-1.439) in men and 0.492 (0.388-0.623) in women. Compared to manual workers, ORs (95% CIs) for private cancer screening of office workers were 1.300 (1.018-1.660) in men and 0.822 (0.616-1.098) in women. In comparison to the least educated men, OR (95% CI) for private cancer screening of the most educated men was statistically significant (1.530 [1.117-2.095]). CONCLUSION: Higher economic status was associated with higher rates of overall and private cancer screening in both sexes and a lower rate of NCSP in women. Male office workers and more educated individuals underwent private cancer screening at a higher rate than manual workers and less educated individuals, respectively. PMID- 27688863 TI - Prevalence and Predictive Factors of Sexual Dysfunction in Iranian Women: Univariate and Multivariate Logistic Regression Analyses. AB - BACKGROUND: Female sexual dysfunction, which can occur during any stage of a normal sexual activity, is a serious condition for individuals and couples. The present study aimed to determine the prevalence and predictive factors of female sexual dysfunction in women referred to health centers in Ilam, the Western Iran, in 2014. METHODS: In the present cross-sectional study, 444 women who attended health centers in Ilam were enrolled from May to September 2014. Participants were selected according to the simple random sampling method. Univariate and multivariate logistic regression analyses were used to predict the risk factors of female sexual dysfunction. Diffe rences with an alpha error of 0.05 were regarded as statistically significant. RESULTS: Overall, 75.9% of the study population exhibited sexual dysfunction. Univariate logistic regression analysis demonstrated that there was a significant association between female sexual dysfunction and age, menarche age, gravidity, parity, and education (P<0.05). Multivariate logistic regression analysis indicated that, menarche age (odds ratio, 1.26), education level (odds ratio, 1.71), and gravida (odds ratio, 1.59) were independent predictive variables for female sexual dysfunction. CONCLUSION: The majority of Iranian women suffer from sexual dysfunction. A lack of awareness of Iranian women's sexual pleasure and formal training on sexual function and its influencing factors, such as menarche age, gravida, and level of education, may lead to a high prevalence of female sexual dysfunction. PMID- 27688864 TI - Development of Epidural and Paraspinal Abscesses after Insufficient Evaluation and Treatment of Acute Pyelonephritis Caused by Staphylococcus aureus. AB - Diagnoses of pyelonephritis caused by Staphylococcus aureus should be accompanied by investigations of concomitant bladder obstruction and metastatic infections, especially to the spine or heart. Complicated pyelonephritis due to S. aureus requires more than 2 weeks of antibiotics, which is the typically recommended treatment duration for pyelonephritis. We describe a patient who was diagnosed with complicated epidural and paraspinal abscesses after insufficient evaluation and treatment of acute pyelonephritis due to S. aureus. A 62-year-old man with type 2 diabetes was admitted with fever, increased urinary frequency, and left flank pain. He was diagnosed with acute pyelonephritis caused by S. aureus. His fever and flank pain subsided after 3 days of intravenous antibiotics. Evaluation of bladder obstruction and metastatic infection were not performed, as he declined further evaluation. The patient was discharged with oral antibiotics and was requested to attend weekly appointments but was lost to follow-up. One month later, the patient presented at the outpatient clinic with similar symptoms. Computed tomography showed recurrent pyelonephritis and a distended bladder. His flank pain persisted despite administration of an opioid agent. Therefore, magnetic resonance imaging was performed, revealing epidural and paraspinal abscesses. Ultrasound-guided aspiration of the paraspinal muscle layer was performed, and blood and percutaneous aspirated fluid cultures revealed S. aureus growth. The pattern of antimicrobial sensitivity was identical to that at his first admission. Following more than 4 weeks of antibiotics, magnetic resonance imaging showed the abscesses had decreased in size. The patient was discharged without neurologic sequelae and was provided with oral antibiotics. PMID- 27688865 TI - Patients' Perceived Quality of Family Physicians' Primary Care with or without 'Family Medicine' in the Clinic Name. AB - BACKGROUND: Patients' perspectives of family medicine according to the physician's identity and role as a primary-care specialist need to be investigated. This study was conducted to investigate the perceived quality of the primary care of family medicine clinics as assessed by patients in a community setting. METHODS: Patients (or their guardians) visiting nine community family medicine clinics were surveyed using the Korean Primary Care Assessment Tool from April 2014 to June 2014. The scores of the Korean Primary Care Assessment Tool domains were compared according to the clinics' designation (or not) as 'family medicine' and the patients' recognition (or not) of the physicians as board-certified family medicine specialists. RESULTS: A total of 196 subjects responded to the questionnaire. They assessed the community clinics' quality of primary care as moderate to high. Of the clinics, those that were not designated as family medicine scored higher than those that were designated as family medicine (P<0.05). The group of patients that recognized a clinic as that of a board-certified family medicine specialist awarded higher scores than the non-recognition group in the domains of coordination function and personalized care (P<0.05). CONCLUSION: The moderate to high scores for the community family medicine clinics' quality of primary care are encouraging. It seems that patients' recognition of the family physician's role and of the physician-patient relationship has a significant influence on their assessment of the quality of primary care.

PMID- 27688867 TI - An Analysis of Electronic Cigarette and Cigarette Advertising in US Women's Magazines. AB - BACKGROUND: Traditional cigarette advertising has existed in the US for over 200 years. Studies suggest that advertising has an impact on the initiation and maintenance of smoking behaviors. In recent years, electronic cigarettes (e cigarettes) emerged on the market as an alternative to the traditional tobacco cigarette. The purpose of this study was to describe advertisements in popular US magazines marketed to women for cigarettes and e-cigarettes. METHODS: This study involved analyzing 99 issues of 14 popular US magazines marketed to women. RESULTS: Compared to advertisements for traditional cigarettes, advertisements for e-cigarettes were more often found in magazines geared toward the 31-40-year old audience (76.5% vs. 53.1%, P = 0.011) whereas traditional cigarette advertisements were nearly equally distributed among women 31-40 and >=40 years. More than three-quarters of the e-cigarette advertisements presented in magazines aimed at the higher median income households compared to a balanced distribution by income for traditional cigarettes (P = 0.033). CONCLUSIONS: Future studies should focus on specific marketing tactics used to promote e-cigarette use as this product increases in popularity, especially among young women smokers. PMID- 27688868 TI - Epidemiological Study of Animal Bites and Rabies in Lorestan Province in West of Iran During 2004-2014 for Preventive Purposes. AB - BACKGROUND: Despite the progress made, animal bites and rabies are one of the important health problems in the country. The purpose of this study was to investigate the epidemiology of animal bites and rabies during 2004-2014 in Lorestan Province to prevent them in population of the province for the future prospective aspects. MATERIALS AND METHODS: In a descriptive cross-sectional study, all those cases bitten in the province, during 2004 and 2014, were studied. The required information about the age, sex, the bitten organ, type of the invasive animal time, and location of the event were collected in questionnaires and then analyzed. RESULTS: The total number of cases of animal rabies during the period of study was 43,892, shown at the rate of 223.23 in 100,000 people. Seventy-eight percent of animal bites in rural areas, 41.42% in the ages 10-29-year-old, 26.8% of cases were students, 56.77% leg bites, and 82.5% of dog bites. Four cases of human rabies were observed during this period. CONCLUSIONS: Rate of animal bites and rabies is high in Lorestan Province. Controlling animals such as dogs and cats in the province through training people at risk, especially among the students, rural areas and inter-sectorial coordination to eliminate stray animals should be considered over and over. Preventive actions to avoid bites are a priority. PMID- 27688869 TI - Tobacco Use and Substance Abuse in Students of Karaj Universities. AB - BACKGROUND: It is clear that tobacco smoking and substance abuse have negative consequences on adolescent and youth's health. Tobacco smoking especially hookah smoking has increased worldwide especially among university students. This study aimed to determine the prevalence of risk-taking behaviors such as cigarette smoking, hookah smoking, alcohol use, and drug abuse and its predictors in students of Karaj universities. METHODS: This cross-sectional study took place in Karaj in January and February 2014. The randomly selected sample consisted of 1959 college students. A self-administered questionnaire was used to measure risk taking behaviors as well as demographic and related risk factors. Logistic regression model was performed in data analysis. RESULTS: The prevalence of cigarette smoking was 9.3%. The prevalence of hookah smoking was 9.3%. 7% of students used illegal drugs and 9.5% of students used alcohol at least once in last 30 days. After adjustment for other factors, being male, living without parents, having smoker friends, and presence any smoker in the family were factors associated with students' risk-taking behaviors. The results showed the co-occurrence of risk-taking behaviors. CONCLUSIONS: The prevalence of tobacco smoking and substance abuse, particular in males, are high. It seems that planning preventive interventions for this part of the population are necessary. This study emphasized the co-occurrence of risky behaviors, so, it is better high risk behaviors simultaneously targeted at reducing or preventing interventions. PMID- 27688870 TI - Sex-specific effects of dietary fatty acids on saliva cortisol and social behavior in guinea pigs under different social environmental conditions. AB - BACKGROUND: Unbalanced dietary intakes of saturated (SFAs) and polyunsaturated (PUFAs) fatty acids can profoundly influence the hypothalamic-pituitary-adrenal (HPA)-axis and glucocorticoid secretions in relation to behavioral performances. The beneficial effects of higher dietary PUFA intakes and PUFA:SFA ratios may also affect social interactions and social-living per se, where adequate physiological and behavioral responses are essential to cope with unstable social environmental conditions. METHODS: Effects of diets high in PUFAs or SFAs and a control diet were investigated in male and female guinea pigs after 60 days of supplementation. Plasma fatty acid patterns served as an indicator of the general fatty acid status. HPA-axis activities, determined by measuring saliva cortisol concentrations, social behaviors, and hierarchy ranks were analyzed during group housing of established single-sexed groups and during challenging social confrontations with unfamiliar individuals of the other groups. RESULTS: The plasma PUFA:SFA ratio was highest in PUFA supplemented animals, with female levels significantly exceeding males, and lowest in SFA animals. SFA males and females showed increased saliva cortisol levels and decreased aggressiveness during group housing, while sociopositive behaviors were lowest in PUFA males. Males generally showed higher cortisol increases in response to the challenging social confrontations with unfamiliar individuals than females. While increasing cortisol concentrations were detected in control and PUFA animals, no such effect was found in SFA animals. During social confrontations, PUFA males showed higher levels of agonistic and sociopositive behaviors and also gained higher dominance ranks among males, which was not detected for females. CONCLUSIONS: While SFAs seemingly impaired cortisol responses and social behaviors, PUFAs enabled adequate behavioral responses in male individuals under stressful new social environmental conditions. This sex-specific effect was possibly related to a general sex difference in the n-3 PUFA bioavailability and cortisol responses, which may indicate that males are more susceptible to changing environmental conditions, and shows how dietary fatty acids can shape social systems. PMID- 27688871 TI - Reduction of apoptosis and preservation of mitochondrial integrity under ischemia/reperfusion injury is mediated by estrogen receptor beta. AB - BACKGROUND: Estrogen improves cardiac recovery after ischemia/reperfusion (I/R) by yet incompletely understood mechanisms. Mitochondria play a crucial role in I/R injury through cytochrome c-dependent apoptosis activation. We tested the hypothesis that 17beta-estradiol (E2) as well as a specific ERbeta agonist improve cardiac recovery through estrogen receptor (ER)beta-mediated mechanisms by reducing mitochondria-induced apoptosis and preserving mitochondrial integrity. METHODS: We randomized ovariectomized C57BL/6N mice 24h before I/R to pre-treatment with E2 or a specific ERbeta agonist (ERbetaA). Isolated hearts were perfused for 20min prior to 30min global ischemia followed by 40min reperfusion. RESULTS: Compared with controls, ERbetaA and E2 treated groups showed a significant improvement in cardiac recovery, i.e. an increase in left ventricular developed pressure, dP/dtmax and dP/dtmin. ERbetaA and E2 pre treatment led to a significant reduction in apoptosis with decreased cytochrome c release from the mitochondria and increased mitochondrial levels of anti apoptotic Bcl2 and ACAA2. Protein levels of mitochondrial translocase inner membrane (TIM23) and mitochondrial complex I of respiratory chain were increased by ERbetaA and E2 pre-treatment. Furthermore, we found a significant increase of myosin light chain 2 (MLC2) phosphorylation together with ERK1/2 activation in E2, but not in ERbetaA treated groups. CONCLUSIONS: Activation of ERbeta is essential for the improvement of cardiac recovery after I/R through the inhibition of apoptosis and preservation of mitochondrial integrity and can be a achieved by a specific ERbeta agonist. Furthermore, E2 modulates MLC2 activation after I/R independent of ERbeta. PMID- 27688872 TI - Anticancer bioactive peptide-3 inhibits human gastric cancer growth by targeting miR-338-5p. AB - BACKGROUND: Cancer incidence and mortality have been increasing in China, making cancer the leading cause of death since 2010 and a major public health concern in the country. Cancer stem cells have been studied in relation to the treatment of different malignancies, including gastric cancer. Anticancer bioactive peptide-3 (ACBP-3) can induce the apoptosis of gastric cancer stem cells (GCSCs) and reduce their tumorigenicity. In the present study, for the first time, we used a miRNA microarray and bioinformatics analysis to identify differentially expressed miRNAs in ACBP-3-treated GCSCs and GCSC-derived tumors in a xenograft model and functionally verified the identified miRNAs. miR-338-5p was selected based on its significant upregulation by ACBP-3 both in cultured GCSCs and in tumor tissues. RESULTS: miR-338-5p was downregulated in GCSCs compared with normal gastric epithelial cells, and the ectopic restoration of miR-338-5p expression in GCSCs inhibited cell proliferation and induced apoptosis, which correlated with the upregulation of the pro-apoptotic Bcl-2 proteins BAK and BIM. We also found that ACBP-3-treated GCSCs could respond to lower effective doses of cisplatin (DDP) or 5-fluorouracil (5-FU), possibly because ACBP-3 induced the expression of miR-338 5p and the BAK and BIM proteins and promoted GCSC apoptosis. CONCLUSIONS: Our data indicate that miR-338-5p is part of an important pathway for the inhibition of human gastric cancer stem cell proliferation by ACBP-3 combined with chemotherapeutics. ACBP-3 could suppress GCSC proliferation and lower the required effective dose of cisplatin or 5-fluorouracil. Therefore, this study provides not only further evidence for the remarkable anti-tumor effect of ACBP-3 but also a possible new approach for the development of GCSC-targeting therapies. PMID- 27688873 TI - The cost and value of cancer drugs - are new innovations outpacing our ability to pay? AB - Cancer drug expenditures have been increasing significantly in countries around the world. A recent paper in the IJHPR provides new knowledge and insights into this global phenomenon by analyzing how it is playing out in an Israeli health plan with over two million members, whose state-of-the-art information systems provide an opportunity to explore these changes in a comprehensive, detailed and reliable manner. There is a wide variation in both the cost-effectiveness and the budget impact of individual drugs. These issues also vary when analyzing drugs in other countries due to differential pricing mechanisms. In addition to drug expenditure, the overall cost of cancer care is increasing, partly due to expenditures on non-pharmacologic treatments and diagnostic testing. With the arrival of new therapies, the future of cancer care is exciting. However, there will be many challenges ahead with regard to the ability to pay for such innovations. In this commentary we discuss the current problems and anticipate the future challenges. PMID- 27688874 TI - Medical education in Israel 2016: five medical schools in a period of transition. AB - ABSTRACT: We reviewed the existing programs for basic medical education (BME) in Israel as well as their output, since they are in a phase of reassessment and transition. The transition has been informed, in part, by evaluation in 2014 by an International Review Committee (IRC). The review is followed by an analysis of its implications as well as the emergent roadmap for the future. The review documents a trend of modernizing, humanizing, and professionalizing Israeli medical education in general, and BME in particular, independently in each of the medical schools. Suggested improvements include an increased emphasis on interactive learner-centered rather than frontal teaching formats, clinical simulation, interprofessional training, and establishment of a national medical training forum for faculty development. In addition, collaboration should be enhanced between medical educators and health care providers, and among the medical schools themselves. The five schools admitted about 730 Israeli students in 2015, doubling admissions from 2000. In 2014, the number of new licenses, including those awarded to Israeli international medical graduates (IMGs), surpassed for the first time in more than a decade the estimated need for 1100 new physicians annually. About 60 % of the licenses awarded in 2015 were to IMGs. CONCLUSIONS: Israeli BME is undergoing continuous positive changes, was supplied with a roadmap for even further improvement by the IRC, and has doubled its output of graduates. The numbers of both Israeli graduates and IMGs are higher than estimated previously and may address the historically projected physician shortage. However, it is not clear whether the majority of newly licensed physicians, who were trained abroad, have benefited from similar recent improvements in medical education similar to those benefiting graduates of the Israeli medical schools, nor is it certain that they will benefit from the further improvements that have recently been recommended for the Israeli medical schools. Inspired by the IRC report, this overview of programs and the updated physician manpower data, we hope the synergy between all stakeholders is enhanced to address the combined medical education quality enhancement and output challenge. PMID- 27688875 TI - Proficiency testing of skin prick testers as part of a quality assurance system. AB - BACKGROUND: Skin prick test is an important diagnostic procedure in clinical allergy but documentation of the quality is often missing. METHODS: We describe a proficiency system to evaluate staff members in relation to the international recommended reproducibility in terms of coefficient of variation (CV < 40 %) and the linearity (coefficient of regression >0.85) based on blinded octuplicate histamine testing using histamine 3, 10, 30 and 100 mg/ml. RESULTS: Fourteen trained allergy nurses participated in the proficiency testing. More than 95 % of the nurses, generated coefficient of variation less than 40 %, and for around 35 % of testers the CV were below 20 % based on wheal area. Regarding the linearity (coefficient of regression), only two nurses produced tests with a value below 0.85. On the contrary, 79 % of testers demonstrated a coefficient of regression >0.95. Depending on the gentleness of the prick procedure, the inter-nurse variability in wheal area varied more than twofold corresponding to a 10-doubling of histamine concentration. This would never have been detected without using a proficiency testing system. CONCLUSION: The described histamine testing provides an objective system for the evaluation of basic skin test quality assessment standards especially for documentation in scientific studies.

AB - BACKGROUND: Prevalence of vancomycin-resistant enterococci has increased in Germany. Here, we report the cluster of linezolid- and vancomycin-resistant Enterococcus faecium (LVRE) in a German department for hematologic stem cell transplantation (HSCT). METHODS: In this retrospective analysis we included all patients with LVRE in a university-based department for HSCT in 2014 and 2015. Patients chart reviews were used to investigate the epidemiology and clinical outcome. Available LVRE isolates underwent detailed microbiological characterization and genotyping by pulsed-field gel electrophoresis (PFGE). RESULTS: In total, 20 patients with LVRE were identified within the observed time period. All except two patients underwent allogeneic HSCT. Surveillance culture results from incoming patients and chart review revealed that 10 of 20 patients were colonized at hospital admission. Eight of 10 patients with in-hospital acquired LVRE had previous linezolid treatment. Analysis of spatio-temporal patterns showed no evidence for LVRE patient-to-patient or environment-to-patient transmission within the HSCT department. In five cases (25 %) LVRE bloodstream infection occurred. Nine LVRE isolates could be saved for characterization. Eight isolates carried vanA, one isolate vanB. PFGE analysis showed that four different LVRE clones were responsible for the cluster. One single genotype was present in six LVRE isolates whereupon the corresponding patients were all referred from the same hospital to the HSCT department. CONCLUSIONS: This is the first report demonstrating the emergence of LVRE in a German HSCT department. (L)VRE screening at patients' admission and appropriate infection control strategies were sufficient to prevent any transmission. Further studies in this predisposed patient collective are warranted.

AB - BACKGROUND: Residents of nursing homes are commonly colonized with methicillin resistant Staphylococcus aureus (MRSA) but there is a limited understanding of the dynamics and determinants of spread in this setting. To address this gap, we sought to use mathematical modeling to assess the epidemic potential of MRSA in nursing homes and to determine conditions under which non-USA300 and USA300 MRSA could be eliminated or reduced in the facilities. METHODS: Model parameters were estimated from data generated during a longitudinal study of MRSA in 6 Wisconsin nursing homes. The data included subject colonization status with strain-specific MRSA collected every 3 months for up to 1 year. Deterministic and stochastic co colonization and single-strain models were developed to describe strain-specific dynamics of MRSA in these facilities. Basic reproduction numbers of strain independent MRSA, non-USA300 and USA300 MRSA were estimated numerically. The impact of antibiotic use in the past 3 months on the prevalence of strain specific MRSA and associated basic reproduction numbers were evaluated. RESULTS: Our models predicted that MRSA would persist in Wisconsin nursing homes, and non USA300 would remain the dominant circulating strain. MRSA eradication was theoretically achievable by elimination of MRSA-positive admissions over the course of years. Substantial reductions in MRSA prevalence could be attained through marked increase in clearance rates or reduction in MRSA-positive admissions sustained over years. The basic reproduction number of strain independent MRSA was 0.18 (95 % CI = 0.13-0.23). Recent antibiotic use increased the prevalence of strain-specific MRSA and associated basic reproduction numbers, but was unlikely to lead to an outbreak. CONCLUSIONS: Based on our model, MRSA elimination from nursing homes, while theoretically possible, was unlikely to be achieved in practice. Decolonization therapy that can sustain higher clearance rates or lower MRSA-positive introductions over years may reduce strain-specific prevalence of MRSA in the facilities, and antibiotic stewardship may contribute to this effort. Large-scale MRSA outbreaks were unlikely in this setting. PMID- 27688878 TI - How rare bone diseases have informed our knowledge of complex diseases. AB - Rare bone diseases, generally defined as monogenic traits with either autosomal recessive or dominant patterns of inheritance, have provided a rich database of genes and associated pathways over the past 2-3 decades. The molecular genetic dissection of these bone diseases has yielded some major surprises in terms of the causal genes and/or involved pathways. The discovery of genes/pathways involved in diseases such as osteopetrosis, osteosclerosis, osteogenesis imperfecta and many other rare bone diseases have all accelerated our understanding of complex traits. Importantly these discoveries have provided either direct validation for a specific gene embedded in a group of genes within an interval identified through a complex trait genome-wide association study (GWAS) or based upon the pathway associated with a monogenic trait gene, provided a means to prioritize a large number of genes for functional validation studies. In some instances GWAS studies have yielded candidate genes that fall within linkage intervals associated with monogenic traits and resulted in the identification of causal mutations in those rare diseases. Driving all of this discovery is a complement of technologies such as genome sequencing, bioinformatics and advanced statistical analysis methods that have accelerated genetic dissection and greatly reduced the cost. Thus, rare bone disorders in partnership with GWAS have brought us to the brink of a new era of personalized genomic medicine in which the prevention and management of complex diseases will be driven by the molecular understanding of each individuals contributing genetic risks for disease. PMID- 27688879 TI - Selective ligninolysis of wheat straw and wood chips by the white-rot fungus Lentinula edodes and its influence on in vitro rumen degradability. AB - BACKGROUND: The present work investigated the influence of lignin content and composition in the fungal treatment of lignocellulosic biomass in order to improve rumen degradability. Wheat straw and wood chips, differing in lignin composition, were treated with Lentinula edodes for 0, 2, 4, 8 and 12 wk and the changes occurring during fungal degradation were analyzed using pyrolysis-gas chromatography-mass spectrometry and detergent fiber analysis. RESULTS: L. edodes preferentially degraded lignin, with only limited cellulose degradation, in wheat straw and wood chips, leaving a substrate enriched in cellulose. Syringyl (S) lignin units were preferentially degraded than guaiacyl (G)-lignin units, resulting in a decreased S/G ratio. A decreasing S/G ratio (wheat straw: r = 0.72, wood chips: r = -0.75) and selective lignin degradation (wheat straw: r = 0.69, wood chips: r = -0.88) were correlated with in vitro gas production (IVGP), a good indicator for rumen degradability. CONCLUSIONS: L. edodes treatment increased the IVGP of wheat straw and wood chips. Effects on IVGP were similar for wheat straw and wood chips indicating that lignin content and 3D-structure of cell walls influence in vitro rumen degradability more than lignin composition. PMID- 27688880 TI - Associations between psychological factors and the effect of home-based physical exercise in women with chronic neck and shoulder pain. AB - BACKGROUND: Exercise is often used in the treatment of chronic neck and shoulder muscle pain. It is likely that psychological aspects have an impact on the results of exercise-based treatments. OBJECTIVES: (1) To examine the associations between psychological factors and the effect of a home-based physical exercise intervention. (2) To examine differences in psychological factors at baseline between (a) subjects who continued in the trial and those who did not and (b) subjects who completed the intervention and those who did not. METHOD: A total of 57 women with chronic neck and shoulder pain were included in a home-based exercise intervention trial. Pain intensity, disability, and psychological factors (anxiety and depression symptoms, catastrophizing, fear-avoidance beliefs, self-efficacy, and pain acceptance) were measured at baseline, after 4-6 months, and after 1 year of exercise. Associations between the psychological factors and changes in pain intensity and disability were analysed, as well as differences in psychological factors at baseline between subjects who continued in and completed the intervention, and those who did not. RESULTS: Associations between positive changes in pain intensity and disability were found for low fear avoidance beliefs and low-pain self-efficacy at baseline. In addition, fear avoidance beliefs at baseline were higher in the subjects who dropped out of the intervention than in those who continued. Pain acceptance at baseline was higher in the subjects who completed the intervention at the end of the trial. CONCLUSION: Particularly, fear-avoidance beliefs and pain self-efficacy should be taken into consideration when implementing home-based physical exercise as treatment for chronic neck pain. In addition, high pain acceptance might improve the adherence to prescribed exercise. PMID- 27688883 TI - First case of a dog bite wound infection caused by Streptococcus minor in human.

At present, the role of Streptococcus minor in bite wound infections is unknown. Further studies on virulence factors are needed to elucidate its pathogenicity mechanisms. PMID- 27688881 TI - MR thermometry for focused ultrasound monitoring utilizing model predictive filtering and ultrasound beam modeling. AB - BACKGROUND: A major challenge in using magnetic resonance temperature imaging (MRTI) to monitor focused ultrasound (FUS) applications is achieving high spatio temporal resolution over a large field of view (FOV). This is important to accurately monitor all ultrasound (US) power depositions. Magnetic resonance (MR) subsampling in conjunction with thermal model-based reconstruction of the MRTI utilizing Pennes bioheat transfer equation (PBTE) is one promising approach. The thermal properties used in the thermal model are often estimated from a pre treatment, low-power sonication. METHODS: In this proof-of-concept study we investigate the use of US simulations computed using the hybrid angular spectrum (HAS) method to estimate the US power deposition density Q, thereby avoiding the pre-treatment sonication and any potential tissue damage. MRTI reconstructions are performed using a thermal model-based reconstruction method called model predictive filtering (MPF). Experiments are performed in a homogeneous gelatin phantom and in a gelatin phantom with embedded plastic skull. MPF reconstructions are compared to separate sonications imaged with fully sampled data over a smaller FOV. Temperature root-mean-square errors (RMSE) and focal spot positions and shapes are evaluated. RESULTS: HAS simulations accurately predict the location of the focal spot (to within 1 mm) in both phantoms. Accurate temperature maps (RMSE below 1 degrees C), where the location of the focal spot agrees well with fully sampled "truth" (to within 1 mm), are also achieved in both phantoms. CONCLUSIONS: HAS simulations can be used to accurately predict the focal spot location in homogeneous media and when focusing through an aberrating plastic skull. The HAS simulated power deposition (Q) patterns can be used in the MPF thermal model-based reconstruction to obtain accurate temperature maps with high spatio-temporal resolution over large FOVs. PMID- 27688882 TI - A spherical-plot solution to linking acceleration metrics with animal performance, state, behaviour and lifestyle. AB - BACKGROUND: We are increasingly using recording devices with multiple sensors operating at high frequencies to produce large volumes of data which are problematic to interpret. A particularly challenging example comes from studies on animals and humans where researchers use animal-attached accelerometers on moving subjects to attempt to quantify behaviour, energy expenditure and condition. RESULTS: The approach taken effectively concatinated three complex lines of acceleration into one visualization that highlighted patterns that were otherwise not obvious. The summation of data points within sphere facets and presentation into histograms on the sphere surface effectively dealt with data occlusion. Further frequency binning of data within facets and representation of these bins as discs on spines radiating from the sphere allowed patterns in dynamic body accelerations (DBA) associated with different postures to become obvious. METHOD: We examine the extent to which novel, gravity-based spherical plots can produce revealing visualizations to incorporate the complexity of such multidimensional acceleration data using a suite of different acceleration derived metrics with a view to highlighting patterns that are not obvious using current approaches. The basis for the visualisation involved three-dimensional plots of the smoothed acceleration values, which then occupied points on the surface of a sphere. This sphere was divided into facets and point density within each facet expressed as a histogram. Within each facet-dependent histogram, data were also grouped into frequency bins of any desirable parameters, most particularly dynamic body acceleration (DBA), which were then presented as discs on a central spine radiating from the facet. Greater radial distances from the sphere surface indicated greater DBA values while greater disc diameter indicated larger numbers of data points with that particular value. CONCLUSIONS: We indicate how this approach links behaviour and proxies for energetics and can inform our identification and understanding of movement-related processes, highlighting subtle differences in movement and its associated energetics. This approach has ramifications that should expand to areas as disparate as disease identification, lifestyle, sports practice and wild animal ecology.

PMID- 27688884 TI - Use of a fictitious community-based virtual teaching platform to aid in the teaching of pharmacy practice skills: Student perspectives after initial implementation. AB - BACKGROUND: Providing patient-centred care requires pharmacy students to learn how to interact effectively and understand individual differences that can influence patients' health. The School of Pharmacy at The University of Auckland, New Zealand (NZ), developed a virtual teaching platform, called NZ Pharmville, which consisted of twenty-one community-based patients who are members of six families; each family had a video vignette associated with it. Bachelor of Pharmacy (BPharm) students, enrolled in the third year pharmacy practice course, were able to view these recorded vignettes as part of their weekly pre-laboratory work for the course. All the clinical cases within the course were based on this community, with the aim of increasing the realism in the practical sessions and increasing patient-centred learning. This study aimed to explore the perspectives of pharmacy students regarding the integration of this virtual community into a third year undergraduate pharmacy practice course. METHODS: An anonymous, voluntary survey which consisted of twenty-one items, 13 requiring a Likert scale response and 8 requiring free text responses, was distributed to all students who had completed the third year pharmacy practice course. The responses to the questions were collated and analysed. Responses to questions one to thirteen were recorded in Excel, and results were presented as the combination of strongly agree and agree, strongly disagree and disagree and neutral. Responses to free text questions were read multiple times before being coded by two members of the research team into broad themes aligned to the overall aims of the evaluation. RESULTS: Eighty-six (80.4 %) of the eligible students completed the survey and the majority of responses were positive towards the benefits of using the virtual community in the course. Responses indicated that many of the students found the integration of the virtual community to be useful preparation for their practical sessions and the majority of students felt that the vignettes made it easier to develop empathy for the patients rather than reading about them. CONCLUSION: The use of virtual communities, for example, NZ Pharmville, show promise as a platform to aid in teaching and learning. The resources in NZ Pharmville allow students ongoing access to patient video clips that attempt to depict a real life situation, and enable students to engage with the fictional characters. The virtual community provided an educational experience which was well received by students. This teaching method appeared to promote active patient-centered learning and allowed students to reflect on and revisit these skills on a weekly basis. PMID- 27688885 TI - The fate of the new pharmacy bill: going backwards or forwards? AB - BACKGROUND: The proposed Pharmacy Bill of Malaysia which served to consolidate and harmonise the existing pharmacy legislation which has been used for more than 60 years. This new Pharmacy Bill contains 17 parts and a total of 170 legislative sections covering laws governing pharmacy practice, medicinal products classification, registration, sale, supply, licensing etc. Our article could serve as a case study on pharmacy jurisprudence and drug regulation as well as the governance for medicines. DISCUSSION: Changes to the colonial era legislation are long overdue as the present pharmaceutical and medical controls are not integrated and various overlaps exist in terms of roles of control. However, various organisations of private general practitioners strongly opposed this Pharmacy Bill and lobbied for a revised version that greatly favours themselves. Thus, the latest revision of this Pharmacy Bill renders the power to medical doctors to not only continue selling and supplying medications but also compound medication. SUMMARY: A complete overhaul of pharmacy legislation in view of the current challenges faced in providing efficient and comprehensive health services in Malaysia is necessary. For the sake of patients' safety and good governance for medicines, the private general practitioners should empower the patients with their needs for prescription and itemised billing. The proposed Pharmacy Bill could make the whole mechanism of managing and controlling the use of medicines more transparent and synchronised. PMID- 27688886 TI - Forces influencing generic drug development in the United States: a narrative review. AB - BACKGROUND: The United States (U.S.) Food and Drug Administration, as protectors of public health, encourages generic drug development and use so that patients can access affordable medications. The FDA, however, has limited mechanisms to encourage generic drug manufacturing. MAIN RESULTS: Generic drug manufacturers make decisions regarding development of products based on expected profitability, influenced by market forces, features of the reference listed drug, and manufacturing capabilities, as well as regulatory restrictions. Barriers to the development of generic drugs include the challenge of demonstrating bioequivalence of some products, particularly those that are considered to be complex generics. CONCLUSIONS: We present here a focused review describing the influences on generic manufacturers who are prioritizing drugs for generic development. We also review proposed strategies that regulators may use to incentivize generic drug development. PMID- 27688887 TI - Assessment of WHO/INRUD core drug use indicators in two tertiary care hospitals of Bahawalpur, Punjab, Pakistan. AB - BACKGROUND: Medicines are a main therapeutic intervention provided within hospitals and their proper use in the outpatient setting is important for patients and the community. The objective of this study was to evaluate drug use patterns in the outpatient departments (OPDs) of two tertiary care hospitals (Bahawal Victoria Hospital and Civil Hospital) in the Bahawalpur district of the Punjab province of Pakistan by employing the standard World Health Organization/International Network of Rational Use of Drugs (WHO/INRUD) drug use indicators. METHODS: A descriptive, cross-sectional study design was employed. For assessing the prescribing indicators a sample of 2400 prescriptions were systematically reviewed out of a total of 1,560,000 prescriptions written from 1st April 2014 to 31st March 2015. A total of 600 randomly selected patients and all pharmacy personnel were observed and interviewed to investigate the patient care and facility-specific indicators. We used the published ideal standards for each of the WHO/INRUD indicators for comparison purposes. RESULTS: Among the prescribing indicators, the average number of drugs per prescription was 2.8 (SD = 1.3), the drugs prescribed by generic name were 56.6 %, the encounters with an antibiotic prescribed were 51.5 %, no injections were prescribed and 98.8 % of the drugs prescribed were from the Essential Drugs List (EDL). Among the patient care indicators, the average consultation time was 1.2 min (SD = 0.8), the average dispensing time was 8.7 s (SD = 4.9), the percentage of drugs actually dispensed was 97.3 %, the percentage of drugs adequately labeled was 100 % and the patients' knowledge of correct dosage schedule was 61.6 %. Among the facility specific indicators, all OPDs had a copy of the EDL and 72.4 % of the key drugs were available in stock. CONCLUSION: Irrational use of drugs was observed in both OPDs. Polypharmacy, brand prescribing, over-prescribing of antibiotics, short consultation and dispensing times, lack of patients' knowledge about prescribed medicines and unavailability of all key drugs in stock were the major issues that need attention of the healthcare authorities. This study necessitates the requirement to implement the relevant WHO recommended core interventions to promote rational use of medicines in these hospital-based OPDs. PMID- 27688888 TI - Comparisons of hearing threshold changes in male workers with unilateral conductive hearing loss exposed to workplace noise: a retrospective cohort study for 8 years. AB - BACKGROUND: The purpose of this study was to investigate hearing threshold changes of workers with unilateral conductive hearing loss who were exposed to workplace noise for 8-years. METHODS: Among 1819 workers at a shipyard in Ulsan, 78 subjects with an air-bone gap >=10 dBHL in unilateral ears were selected. Factors that could affect hearing were acquired from questionnaires, physical examinations, and biochemistry examinations. Paired t-test was conducted to compare the hearing threshold changes over time between conductive hearing loss (CHL) ear and sensorineural hearing loss (SNHL) ear. RESULTS: The study included male subjects aged 48.7 +/- 2.9, having worked for 29.8 +/- 2.7 years. Hearing thresholds increased significantly in CHL ears and SNHL ears at all frequencies (0.5-6 kHz) during follow-up period (p < 0.05). The threshold change at 4 kHz was 3.2 dBHL higher in SNHL ears which was statistically significant (p < 0.05). When workers were exposed to noise levels of 85 dBA and above, threshold change at 4 kHz was 5.6 dBHL higher in SNHL ears which was statistically significant (p < 0.05). Among workers aged below 50, the threshold change values were lower in low frequency (0.5-2 kHz) in SNHL ears, with a small range of changes, whereas in high-frequency (3-6 kHz), the range of changes was greater SNHL ears (p < 0.05). Among workers aged 50 and above, SNHL ears showed a wider range of changes in both high- and low-frequency areas (p < 0.05). CONCLUSIONS: At high-frequencies, particularly at 4 kHz, the range of hearing threshold changes was lower in ears with conductive hearing loss than in contralateral ears. This is suggested as a protective effect against noise exposure. PMID- 27688889 TI - Comparative analysis of Cucurbita pepo metabolism throughout fruit development in acorn squash and oilseed pumpkin. AB - Both the fruit mesocarp and the seeds of winter squash can be used for consumption, although the focus of breeding efforts varies by cultivar. Cultivars bred for fruit consumption are selected for fruit mesocarp quality traits such as carotenoid content, percent dry matter, and percent soluble solids, while these traits are essentially ignored in oilseed pumpkins. To compare fruit development in these two types of squash, we sequenced the fruit transcriptome of two cultivars bred for different purposes: an acorn squash, 'Sweet REBA', and an oilseed pumpkin, 'Lady Godiva'. Putative metabolic pathways were developed for carotenoid, starch, and sucrose synthesis in winter squash fruit and squash homologs were identified for each of the structural genes in the pathways. Gene expression, especially of known rate-limiting and branch point genes, corresponded with metabolite accumulation both across development and between the two cultivars. Thus, developmental regulation of metabolite genes is an important factor in winter squash fruit quality. PMID- 27688891 TI - Longitudinal changes in desired body weight compared to changes in body weight: evidence of adaptation to weight gain? AB - BACKGROUND: Overweight individuals desire a lower weight than they actually have. Little is known on the extent to which this discrepancy is reduced over time due to adaptation or resignation. The aim of this study is to describe cross sectional relationships and longitudinal changes in desired body weight and differences between actual and desired body weight according to gender, age and category of body mass index in a large, adult cohort in Tromso, Norway. METHODS: Cross-sectional analyses of 8960 men and 9992 women aged 25-69 participating in Tromso 4 (during 1994-1995), and longitudinal analyses of 3210 men and 3689 women participating in both Tromso 4 (during 1994-1995) and Tromso 6 (during 2007 2008). Simple descriptive statistics and linear regression was used to describe actual and desired weight, the difference between them, and how gender and age are related to the changes in actual and desired weight over this 13-year period. RESULTS: The difference between actual and desired body weight was largest for the obese and higher among the overweight than the normal weight for both genders. While normal weight men were quite satisfied with their body weight, normal weight women were not. Actual weight increased more than desired weight for all age groups and both genders except the oldest women. The difference between change in actual body weight and change in desired body weight during the 13-year follow-up was significantly larger among men (2.0 kg) than women (1.5 kg) (p < 0.001), and larger among young than older adults (p < 0.001). Adjusting for level of education had no impact on this relationship. Furthermore, the association between age and the difference between change in actual body weight during the 13 years and change in desired body weight in the same period did not differ between men and women and, in gender specific analyses, between subjects with normal weight and those who were overweight or obese at start of follow-up. CONCLUSION: Older people adapt more to weight gain than younger age groups, with clear gender differences. Further studies of longitudinal changes in desired weight are warranted. PMID- 27688892 TI - Changes in waist circumference and the prevalence of abdominal obesity during 1994-2008 - cross-sectional and longitudinal results from two surveys: the Tromso Study. AB - BACKGROUND: Abdominal obesity increases all-cause mortality and is a risk factor for a number of diseases. There are few population-based studies of the longitudinal changes of abdominal obesity. METHODS: Based on data from the Tromso Study, we studied gender- and age-specific mean waist circumference and prevalence of abdominal overweight and abdominal obesity in two surveys in 1994 1995 (Tromso 4, 6812 men and women aged 25 to 84) and 2007-2008 (Tromso 6, 12,493 men and women aged 30 to 87). Furthermore, we describe the longitudinal changes of waist circumference and abdominal obesity during 13 years in 3144 subjects (aged 25-69 in 1994) who attended both surveys. RESULTS: Cross-sectional analyses found a higher mean waist circumference in men than women and a direct relationship with age in both men and women in both Tromso 4 and in Tromso 6. As the WHO cut-off points for abdominal obesity are gender-specific, however, the prevalence of abdominal obesity was lower in men than in women. In 2007-2008, approximately 37 and 55 % of men and women, respectively, were classified as abdominally obese. Thirteen years before, in 1994-1995, the corresponding figures were 20 and 35 %. Longitudinal analyses of changes during the 13-year period clearly demonstrated that mean waist circumference increased in all examined birth cohorts in both men (mean change 6.1 cm) and women (mean change 8.4 cm), but increased more markedly the younger the subjects were. The prevalence of abdominal obesity in men aged 25-34 increased from 5 % in 1994 to 31 % 13 years later. The prevalence of abdominal obesity more than doubled among both men and women. CONCLUSIONS: The increasing mean waist circumference is of concern. There is a need for further longitudinal studies of the changes in waist circumference.

AB - OBJECTIVE: To analyse the prevalence of malnutrition among paediatric patients at the time of hospital admission throughout a calendar year in a tertiary-level hospital and to identify those patients and/or groups of pathologies with a higher risk of malnutrition. DESIGN: Observational (retrospective evaluation of nutrition status). SETTING: Navarra Hospital Complex, Pamplona, Spain. PARTICIPANTS: A total of 852 patients hospitalised in 2013 in a Spanish tertiary level paediatric hospital (462 males and 390 females). MAIN OUTCOME MEASURES: Sex, age, body mass index at the moment of admission and days of hospitalisation and diagnosis codified according to the International Classification of Diseases were registered. RESULTS: The prevalence of malnutrition patients registered at the moment of admission was 8.2%. Diseases of the nervous system (22.9%), together with diseases of the respiratory system (22.9%), infectious diseases (18.6%), congenital malformations (11.4%) and diseases of the genitourinary system (8.6%) account for 84.4% of the cases with malnutrition. CONCLUSIONS: The overall prevalence rate for malnutrition in paediatric patients at the moment of admission in our hospital was 8.2%, being a figure similar to those published in occidental countries. It should be mandatory to accomplish an initial screening and follow-up during hospitalisation of younger patients and those suffering from diseases of the nervous and/or respiratory system and, especially, from congenital diseases.

PMID- 27688890 TI - Biosynthesis and molecular actions of specialized 1,4-naphthoquinone natural products produced by horticultural plants. AB - The 1,4-naphthoquinones (1,4-NQs) are a diverse group of natural products found in every kingdom of life. Plants, including many horticultural species, collectively synthesize hundreds of specialized 1,4-NQs with ecological roles in plant-plant (allelopathy), plant-insect and plant-microbe interactions. Numerous horticultural plants producing 1,4-NQs have also served as sources of traditional medicines for hundreds of years. As a result, horticultural species have been at the forefront of many basic studies conducted to understand the metabolism and function of specialized plant 1,4-NQs. Several 1,4-NQ natural products derived from horticultural plants have also emerged as promising scaffolds for developing new drugs. In this review, the current understanding of the core metabolic pathways leading to plant 1,4-NQs is provided with additional emphasis on downstream natural products originating from horticultural species. An overview on the biochemical mechanisms of action, both from an ecological and pharmacological perspective, of 1,4-NQs derived from horticultural plants is also provided. In addition, future directions for improving basic knowledge about plant 1,4-NQ metabolism are discussed.

PMID- 27688898 TI - Discussing sudden unexpected death in epilepsy: Are we empowering our patients? A questionnaire survey. AB - OBJECTIVE: To examine patient knowledge about sudden unexpected death in epilepsy (SUDEP) compared to other risks in epilepsy. To explore patients' experiences surrounding SUDEP disclosure and opinions on how information should be delivered. DESIGN: A cross-sectional questionnaire. SETTING: Royal Free Hospital, London outpatient epilepsy clinics. PARTICIPANTS: New and follow-up patients attending epilepsy clinics at a London teaching hospital over six months. Patients identified as being at risk of suffering negative emotional or psychological consequences of SUDEP discussions were excluded. MAIN OUTCOME MEASURES: Patient knowledge about epilepsy risks; patient opinion regarding source, timing and delivery of SUDEP information; impact on health seeking behaviour. RESULTS: Ninety-eight per cent of patients were aware of medication adherence, 84% of factors influencing seizure frequency, 78% of driving regulations, 50% of SUDEP and 38% of status epilepticus; 72% of patients felt that SUDEP information should be given to all patients. Preferences for timing of SUDEP discussions varied between those wanting information at diagnosis (40%) and those preferring to receive it after three clinic appointments (18%) to avoid information overload at the first consultation. Emotional responses (48% positive, 38% negative) predominated over measurable behavioural change following SUDEP discussions. CONCLUSIONS: Less than half the patients knew about SUDEP and status epilepticus. Although the majority of patients with epilepsy wish to be informed about SUDEP early on in their diagnosis, information must be delivered in a way that promotes patient knowledge and empowerment. PMID- 27688899 TI - Patterns and trends in mortality among HIV-infected and HIV-uninfected patients in a major Internal Medicine Unit in Yaounde, Cameroon: a retrospective cohort study. AB - OBJECTIVE: To describe the trends in mortality and the spectrum of disease in HIV infected and -uninfected inpatients in a population in Yaounde. DESIGN: A retrospective study. SETTING: Internal Medicine Unit, University Hospital Centre, Yaounde, Cameroon. PARTICIPANTS: All deaths registered between January 2000 and May 2007 in the unit. MAIN OUTCOMES MEASURES: Sociodemographic characteristics, clinical features and results of all investigations done, cause of death. RESULTS: During the study period, 362 deaths were registered, consisting of 281 (77.6%) in HIV-infected patients, 54.4% of which were women. HIV-infected patients were younger (mean age: 40.2 (SD: 11.6) vs. 55.5 (SD: 18.3) years, p < 0.001) and economically active (60.3% vs. 24.4%, p < 0.001). Most HIV-infected patients (77.6%) were classified as WHO stage IV, with the rest being WHO stage III. Most HIV-infected patients (87.8%) had evidence of profound immunosuppression (CD4 < 200 cells/mm(3)). The mortality trend appeared to be declining with appropriate interventions. The most frequent causes of death in HIV-infected patients were pleural/pulmonary tuberculosis (34.2%), undefined meningoencephalitis (20.3%), other pneumonias (18.2%), toxoplasmosis (16.4%), cryptococcal meningitis (14.2%) and Kaposi sarcoma (15.7%). HIV-uninfected patients died mostly as a result of chronic diseases including liver diseases (17.3%), kidney failure (13.6%), congestive heart failure (11.1%) and stroke (9.9%). CONCLUSION: There was a declining mortality due to HIV with appropriate interventions such as subsidised tests for HIV-infected patients, increased availability of HAART and other medications for prevention and treatment of opportunistic infections. The spectrum of HIV disease was wide and preventable. PMID- 27688900 TI - Plasma tenofovir trough concentrations are associated with renal dysfunction in Japanese patients with HIV infection: a retrospective cohort study. AB - BACKGROUND: Plasma tenofovir (TFV) trough concentrations may be relevant for tenofovir disoproxil fumarate (TDF)-induced renal dysfunction. The purpose of this study was to determine the association between plasma TFV trough concentrations and TDF-induced renal dysfunction in Japanese patients with human immunodeficiency virus (HIV) infection. METHODS: A 48-week, retrospective cohort study was performed with Japanese patients with HIV infection who started a TDF containing combination antiretroviral therapy regimen. Plasma TFV trough concentrations were obtained at steady state. The following variables were included in the analysis: sex, age, body weight, body mass index (BMI), serum creatinine, CD4+ cell count, HIV-RNA, concomitant medications, comorbidities, plasma TFV trough concentrations, and estimated glomerular filtration rate (eGFR). For comparisons of variables, we used Mann-Whitney U tests or Fisher's exact tests. Then, variables associated with renal dysfunction in the univariate analysis were entered into correlation analysis. RESULTS: The analysis included 11 patients. The rate of decrease in eGFR was significantly correlated with body weight (Spearman correlation = -0.645, p = 0.041), BMI (Spearman correlation = 0.682, p = 0.031), and plasma TFV trough concentrations (Spearman correlation = 0.709, p = 0.025). CONCLUSIONS: Despite the small sample size, our findings suggest that higher plasma TFV trough concentrations may cause TDF-induced renal dysfunction. To prevent TDF-induced renal dysfunction, we propose that individual monitoring of plasma TFV trough concentrations should be performed in Japanese patients with HIV infection. PMID- 27688902 TI - Neuromuscular study of early branching Diuronotus aspetos (Paucitubulatina) yields insights into the evolution of organs systems in Gastrotricha. AB - BACKGROUND: Diuronotus is one of the most recently described genera of Paucitubulatina, one of the three major clades in Gastrotricha. Its morphology suggests that Diuronotus is an early branch of Paucitubulatina, making it a key taxon for understanding the evolution of this morphologically understudied group. Here we test its phylogenetic position employing molecular data, and provide detailed descriptions of the muscular, nervous, and ciliary systems of Diuronotus aspetos, using immunohistochemistry and confocal laser scanning microscopy. RESULTS: We confirm the proposed position of D. aspetos within Muselliferidae, and find this family to be the sister group to Xenotrichulidae. The muscular system, revealed by F-actin staining, shows a simple, but unique organization of the trunk musculature with a reduction to three pairs of longitudinal muscles and addition of up to five pairs of dorso-ventral muscles, versus the six longitudinal and two dorso-ventral pairs found in most Paucitubulatina. Using acetylated alpha-tubulin immunoreactivity, we describe the pharynx in detail, including new nervous structures, two pairs of sensory cilia, and a unique canal system. The central nervous system, as revealed by immunohistochemistry, shows the general pattern of Gastrotricha having a bilobed brain and a pair of ventro longitudinal nerve cords. However, in addition are found an anterior nerve ring, several anterior longitudinal nerves, and four ventral commissures (pharyngeal, trunk, pre-anal, and terminal). Two pairs of protonephridia are documented, while other Paucitubulatina have one. Moreover, the precise arrangement of multiciliated cells is unraveled, yielding a pattern of possibly systematic importance. CONCLUSION: Several neural structures of Diuronotus resemble those found in Xenotrichula (Xenotrichulidae) and may constitute new apomorphies of Paucitubulatina, or even Gastrotricha. In order to test these new evolutionary hypotheses, comparable morphological data from other understudied gastrotrich branches and a better resolution of the basal nodes of the gastrotrich phylogeny are warranted. Nonetheless, the present study offers new insights into the evolution of organ systems and systematic importance of so-far neglected characters in Gastrotricha. PMID- 27688901 TI - Correlation between blood magnesium and calcium concentration in patients treated with an anti-EGFR antibody. AB - BACKGROUND: Hypomagnesemia is one of the characteristic side effects of the human anti-epidermal growth factor receptor (EGFR) monoclonal antibodies, cetuximab and panitumumab. The major mechanism of anti-EGFR antibody-related hypomagnesemia is suppression of EGFR-mediated urinary Mg(2+) reabsorption in both the renal tubule the intestinal tract. Since Mg(2+) is known to affect blood Ca(2+) levels through regulation of parathyroid hormone (PTH) secretion, we investigated the correlation between Ca(2+) and Mg(2+) concentration in blood. METHODS: Between April 2012 and October 2015, blood Mg(2+) and Ca(2+) concentrations (albumin corrected value) of 22 colon cancer patients undergoing treatment with either cetuximab or panitumumab at Toyooka Public Hospital were measured simultaneously. RESULTS: Hypomagnesemia (of all Grades) was reported in 13 of 22 patients. Two patients had hypomagnesemia of severity > Grade 3. Changes in blood Mg(2+) and Ca(2+) concentration showed a significant correlation (r(2) = 0.7455), which could be expressed using the following equation, Ca(2+) concentration = 1.4268 * (Mg(2+) concentration) + 7.1126. CONCLUSION: Since the early stages of hypomagnesemia produce no characteristic clinical symptoms, it is easily overlooked until it becomes severe. The investigation results suggest that if low blood Ca(2+) concentration (mg/dL) is observed in patients administered anti-EGFR antibodies, early evaluation of blood Mg(2+) concentration (mg/dL) and prompt supportive care are required to prevent aggravation of hypomagnesemia. PMID- 27688903 TI - CRISPR, a Crossroads in Genetic Intervention: Pitting the Right to Health against the Right to Disability. AB - Reproductive genetic technologies (RGTs), including gene-editing technology, are being discovered and refined at an exponential pace. One gene-editing innovation that demands our swift attention is CRISPR/Cas9, a system of clustered regularly interspaced short palindromic repeats and a protein called Cas9. As CRISPR and other RGTs continue being developed, we must remain vigilant concerning the potential implications of genetic-engineering technology on our interpersonal and legal relationships. In the face of increasingly numerous and refined RGTs, we must maintain the rights of everyone: potential parents, prospective children, and individuals (both living and prospective) with disabilities. For those who wish to become parents, how should procreation be regulated in light of developing RGTs, especially gene-editing technology? What duties do parents owe their children, and when does such a duty attach? What role should RGTs play in parents' fulfillment of their duties to their children? This article will contextualize the right to health and what I will term the "right to disability" in the CRISPR/Cas9 landscape. The article will then explore these rights in reference to the "subjunctive-threshold" interpretation of harm. Finally, I will argue that RGTs must be thoughtfully regulated, with such regulations taking into account the opinions of geneticists, bioethicists, and lay people concerning both the right to health and the right to disability. PMID- 27688904 TI - C1Q Assay Results in Complement-Dependent Cytotoxicity Crossmatch Negative Renal Transplant Candidates with Donor-Specific Antibodies: High Specificity but Low Sensitivity When Predicting Flow Crossmatch. AB - The aim of the present study was to describe the association of positive flow cross match (FXM) and C1q-SAB. Methods. In this observational, cross-sectional, and comparative study, patients included had negative AHG-CDC-XM and donor specific antibodies (DSA) and were tested with FXM. All pretransplant sera were tested with C1q-SAB assay. Results. A total of 50 donor/recipient evaluations were conducted; half of them had at least one C1q+ Ab (n = 26, 52%). Ten patients (20.0%) had DSA C1q+ Ab. Twenty-five (50%) FXMs were positive. Factors associated with a positive FXM were the presence of C1q+ Ab (DSA C1q+ Ab: OR 27, 2.80 259.56, P = 0.004, and no DSA C1q+ Ab: OR 5, 1.27-19.68, P = 0.021) and the DSA LABScreen-SAB MFI (OR 1.26, 95% CI 1.06-1.49, P = 0.007). The cutoff point of immunodominant LABScreen SAB DSA-MFI with the greatest sensitivity and specificity to predict FXM was 2,300 (sensitivity: 72% and specificity: 75%). For FXM prediction, DSA C1q+ Ab was the most specific (95.8%, 85-100) and the combination of DSA-MFI > 2,300 and C1q+ Ab was the most sensitive (92.0%, 79.3 100). Conclusions. C1q+ Ab and LABScreen SAB DSA-MFI were significantly associated with FXM. DSA C1q+ Ab was highly specific but with low sensitivity. PMID- 27688905 TI - Impact of Recipient and Donor Obesity Match on the Outcomes of Liver Transplantation: All Matches Are Not Perfect. AB - There is a paucity of literature examining recipient-donor obesity matching on liver transplantation outcomes. The United Network for Organ Sharing database was queried for first-time recipients of liver transplant whose age was >=18 between January 2003 and September 2013. Outcomes including patient and graft survival at 30 days, 1 year, and 5 years and overall, liver retransplantation, and length of stay were compared between nonobese recipients receiving a graft from nonobese donors and obese recipient-obese donor, obese recipient-nonobese donor, and nonobese recipient-obese donor pairs. 51,556 LT recipients were identified, including 34,217 (66%) nonobese and 17,339 (34%) obese recipients. The proportions of patients receiving an allograft from an obese donor were 24% and 29%, respectively, among nonobese and obese recipients. Graft loss (HR: 1.27; 95% CI: 1.09-1.46; p = 0.002) and mortality (HR: 1.38; 95% CI: 1.16-1.65; p < 0.001) at 30 days were increased in the obese recipient-obese donor pair. However, 1 year graft (HR: 0.83; 95% CI: 0.74-0.93; p = 0.002) and patient (HR: 0.84; 95% CI: 0.74-0.95; p = 0.007) survival and overall patient (HR: 0.93; 95% CI: 0.86 1.00; p = 0.042) survival were favorable. There is evidence of recipient and donor obesity disadvantage early, but survival curves demonstrate improved long term outcomes. It is important to consider obesity in the donor-recipient match. PMID- 27688906 TI - The Intoxication Effects of Methanol and Formic Acid on Rat Retina Function. AB - Objective. To explore the potential effects of methanol and its metabolite, formic acid, on rat retina function. Methods. Sprague-Dawley rats were divided into 3- and 7-day groups and a control. Experimental groups were given methanol and the control group were provided saline by gavage. Retinal function of each group was assessed by electroretinogram. Concentrations of methanol and formic acid were detected by GC/HS and HPLC, respectively. Results. The a and b amplitudes of methanol treated groups decreased and latent periods delayed in scotopic and photopic ERG recordings. The summed amplitudes of oscillatory potentials (OPs) of groups B and C decreased and the elapsed time delayed. The amplitudes of OS1, OS3, OS4, and OS5 of group B and OS3, OS4, and OS5 of group C decreased compared with the control group. The IPI1 of group B and IPI1-4 of group C were broader compared with the control group and the IPI1-4 and ET of group B were broader than group C. CONCLUSIONS: Both of scotopic and photopic retinal functions were impaired by methanol poisoning, and impairment was more serious in the 7-day than in the 3-day group. OPs, especially later OPs and IPI2, were more sensitive to methanol intoxication than other eletroretinogram subcomponents. PMID- 27688907 TI - Scleral Buckling for Rhegmatogenous Retinal Detachment Associated with Pars Planitis. AB - Purpose. To evaluate the surgical outcome of scleral buckling (SB) in rhegmatogenous retinal detachment (RRD) patients associated with pars planitis. Methods. Retrospective review of RRD patients (32 eyes of pars planitis RRD and 180 eyes of primary RRD) who underwent SB. We compared primary and final anatomical success rates and visual outcomes between two groups. Results. Primary and final anatomical success were achieved in 25 (78.1%) and 31 (96.8%) eyes in the pars planitis RRD group and in 167 eyes (92.7%) and 176 eyes (97.7%) in primary RRD group, respectively. Both groups showed significant visual improvement (p < 0.001) and there were no significant differences in final visual acuity. Pars planitis RRD group was associated with higher rate of postoperative proliferative vitreoretinopathy (PVR) development (12.5% versus 2.8%, p = 0.031). Pars planitis and high myopia were significant preoperative risk factors and pseudophakia was borderline risk for primary anatomical failure after adjusting for various clinical factors. Conclusions. Pars planitis associated RRD showed inferior primary anatomical outcome after SB due to postoperative PVR development. However, final anatomical and visual outcomes were favorable. RRD cases associated with pars planitis, high myopia, and pseudophakia might benefit from different surgical approaches, such as combined vitrectomy and SB.

PMID- 27688908 TI - Corneal Biomechanical Findings in Contact Lens Induced Corneal Warpage. AB - Purpose. To evaluate the difference in biomechanical properties between contact lens induced corneal warpage and normal and keratoconic eyes. Method. Prospective observational case control study, where 94 eyes of 47 warpage suspicious and 46 eyes of 23 keratoconic patients were included. Warpage suspected cases were followed until a definite diagnosis was made (warpage, normal, or keratoconus). Results. 44 eyes of 22 patients had contact lens related corneal warpage. 46 eyes of 23 people were diagnosed as nonwarpage normal eyes. 46 eyes of 23 known keratoconus patients were included for comparison. The mean age of the participants was 23.8 +/- 3.8 years, and 66.2% of the subjects were female. The demographic and refractive data were not different between warpage and normal groups but were different in the keratoconus group. The biomechanical properties (corneal hysteresis or CH and corneal resistance factor or CRF) were different with the highest value in the warpage group followed by normal and keratoconus groups. CRF was 10.08 +/- 1.75, 9.23 +/- 1.22, and 7.38 +/- 2.14 and CH was 10.21 +/- 1.57, 9.59 +/- 1.21, and 8.69 +/- 2.34 in the warpage, normal, and keratoconus groups, respectively. Conclusion. Corneal biomechanics may be different in people who develop contact lens induced warpage. PMID- 27688910 TI - Evaluation of Anterior Chamber Volume in Cataract Patients with Swept-Source Optical Coherence Tomography. AB - Purpose. To evaluate the anterior chamber volume in cataract patients with Swept Source Optical Coherence Tomography (SS-OCT) and its influencing factors. Methods. Anterior chamber volume of 92 cataract patients was evaluated with SS OCT in this cross-sectional study. Univariate analyses and multiple linear regression were used to investigate gender, age, operated eye, posterior vitreous detachment, lens opacity grading, and axial length (AXL) related variables capable of influencing the ACV. Results. The average ACV was 139.80 +/- 38.21 mm(3) (range 59.41 to 254.09 mm(3)). The average ACV was significantly larger in male patients than in female patients (P = 0.001). ACV was negatively correlated with age and LOCS III cortical (C) grading of the lens (Pearson's correlation analysis, r = -0.443, P < 0.001, and Spearman's correlation analysis, rho = 0.450, P < 0.001). ACV was also increased with AXL (Pearson's correlation analysis, r = 0.552, P < 0.001). Multiple linear regression showed that, with all of the covariates entered into the model, gender (P = 0.002), age (P = 0.015), LOCS III C grade (P = 0.043), and AXL (P = 0.001) were still associated with ACV (F = 10.252 P < 0.001 R (2) = 0.498). Conclusion. With SS-OCT, we found that, in healthy cataract patients, ACV varied significantly among different subjects. Influencing factors that contribute to reduced ACV were female gender, increased age, LOCS III C grade, and shorter AXL. PMID- 27688911 TI - Can Transcutaneous CO2 Tension Be Used to Calculate Ventilatory Dead Space? A Pilot Study. AB - Dead space fraction (V d/V t) measurement performed using volumetric capnography requires arterial blood gas (ABG) sampling to estimate the partial pressure of carbon dioxide (PaCO2). In recent years, transcutaneous capnography (PtcCO2) has emerged as a noninvasive method of estimating PaCO2. We hypothesized that PtcCO2 can be used as a substitute for PaCO2 in the calculation of V d/V t. In this prospective pilot comparison study, 30 consecutive postcardiac surgery mechanically ventilated patients had V d/V t calculated separately using volumetric capnography by substituting PtcCO2 for PaCO2. The mean V d/V t calculated using PaCO2 and PtcCO2 was 0.48 +/- 0.09 and 0.53 +/- 0.08, respectively, with a strong positive correlation between the two methods of calculation (Pearson's correlation = 0.87, p < 0.05). Bland-Altman analysis showed a mean difference of -0.05 (95% CI: -0.01 to -0.09) between the two methods. PtcCO2 measurements can provide a noninvasive means to measure V d/V t, thus accessing important physiologic information and prognostic assessment in patients receiving mechanical ventilation. PMID- 27688912 TI - Comparative Proteomic Analysis of Differential Proteins in Response to Aqueous Extract of Quercus infectoria Gall in Methicillin-Resistant Staphylococcus aureus. AB - The aim of this study is to analyze the differential proteins in MRSA ATCC 33591 treated with aqueous extract from Q. infectoria gall. Protein extracts were obtained from MRSA cells by sonication and were separated by 2D polyacrylamide gels. Protein spots of interest were extracted from the gels and identified using LC-ESI-QTOF MS. The concentration of Q. infectoria extract used for 2D-gel electrophoresis was subinhibitory concentration. Minimum inhibitory concentration (MIC) value of the extract against MRSA was 19.50 MUg/mL with bacteriostatic action at 1x MIC from time-kill assay. However, the extract exhibited dose dependent manner and was bactericidal at 4x MIC with more than 3 log10 CFU/mL reduction at 4 h. 2D-GE map showed that 18 protein spots were upregulated and another six were downregulated more than twofold (p < 0.05) after treatment with subinhibitory concentration. Out of six proteins being downregulated, four proteins were identified as ferritin and catalase, branched-chain alpha-keto acid dehydrogenase subunit E2, and succinyl-CoA ligase [ADP-forming] subunit beta. Seven upregulated proteins which have been successfully identified were 3 hydroxyacyl-CoA dehydrogenase, NAD binding domain protein, formate C acetyltransferase, 3-hydroxyacyl-[acyl-carrier-protein] dehydratase FabZ, NAD dependent epimerase/dehydratase family protein, and phosphopantothenoyl cysteine decarboxylase. It is postulated that the main mechanism of aqueous extract from gall of Q. infectoria was most likely involved in energy metabolism and protein stress. PMID- 27688913 TI - Predictors of Gestational Weight Gain among White and Latina Women and Associations with Birth Weight. AB - This study examined racial/ethnic differences in gestational weight gain (GWG) predictors and association of first-trimester GWG to overall GWG among 271 White women and 300 Latina women. Rates of within-guideline GWG were higher among Latinas than among Whites (28.7% versus 24.4%, p < 0.016). Adjusted odds of above guideline GWG were higher among prepregnancy overweight (OR = 3.4, CI = 1.8-6.5) and obese (OR = 4.5, CI = 2.3-9.0) women than among healthy weight women and among women with above-guideline first-trimester GWG than among those with within guideline first-trimester GWG (OR = 4.9, CI = 2.8-8.8). GWG was positively associated with neonate birth size (p < 0.001). Interventions targeting prepregnancy overweight or obese women and those with excessive first-trimester GWG are needed. PMID- 27688914 TI - The Prevalence of MRSA Nasal Carriage in Preoperative Pediatric Orthopaedic Patients. AB - Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) has been described as a risk factor for postsurgical infection. The purpose of this study is to determine the prevalence of MRSA in pediatric orthopaedic patients and whether being a MRSA carrier is a predictor of postoperative infection. Six hundred and ninety-nine consecutive pediatric patients who underwent MRSA nasal screening prior to surgery were studied. Postoperative cultures, total surgical site infections (SSIs), and epidemiological and surgical prophylaxis data were reviewed. Forty-four of 699 patients (6.29%) screened positive for MRSA. Nine of the 44 patients (20.5%) that screened positive for MRSA had a subsequent SSI compared to 10 of the 655 patients (1.52%) that screened negative (p < 0.05). All 9 patients with a SSI had myelomeningocele. The prevalence of MRSA was 6.30% and was predictive of postoperative infection. Children with myelomeningocele were at the highest risk for having a positive MRSA screening and developing SSI.

PMID- 27688915 TI - Wnt5a Increases the Glycolytic Rate and the Activity of the Pentose Phosphate Pathway in Cortical Neurons. AB - In the last few years, several reports have proposed that Wnt signaling is a general metabolic regulator, suggesting a role for this pathway in the control of metabolic flux. Wnt signaling is critical for several neuronal functions, but little is known about the correlation between this pathway and energy metabolism. The brain has a high demand for glucose, which is mainly used for energy production. Neurons use energy for highly specific processes that require a high energy level, such as maintaining the electrical potential and synthesizing neurotransmitters. Moreover, an important metabolic impairment has been described in all neurodegenerative disorders. Despite the key role of glucose metabolism in the brain, little is known about the cellular pathways involved in regulating this process. We report here that Wnt5a induces an increase in glucose uptake and glycolytic rate and an increase in the activity of the pentose phosphate pathway; the effects of Wnt5a require the intracellular generation of nitric oxide. Our data suggest that Wnt signaling stimulates neuronal glucose metabolism, an effect that could be important for the reported neuroprotective role of Wnt signaling in neurodegenerative disorders. PMID- 27688917 TI - Compartment Syndrome as a Result of Systemic Capillary Leak Syndrome. AB - Objective. To describe a single case of Systemic Capillary Leak Syndrome (SCLS) with a rare complication of compartment syndrome. Patient. Our patient is a 57 year-old male, referred to our hospital due to polycythemia (hemoglobin (Hgb) of 220 g/L), hypotension, acute renal failure, and bilateral calf pain. Measurements and Main Results. The patient required bilateral forearm, thigh, and calf fasciotomies during his ICU stay and continuous renal replacement therapy was instituted following onset of acute renal failure and oliguria. Ongoing hemodynamic (Norepinephrine and Milrinone infusion) and respiratory (ventilator) support in the ICU was provided until resolution of intravascular fluid extravasation. Conclusions. SCLS is an extremely rare disorder characterized by unexplained episodic capillary hyperpermeability, which causes shift of volume and protein from the intravascular space to the interstitial space. Patients present with significant hypotension, hemoconcentration, hypovolemia, and oliguria. Severe edema results from leakage of fluid and proteins into tissue. The most important part of treatment is maintaining stable hemodynamics, ruling out other causes of shock and diligent monitoring for complications. Awareness of the clinical syndrome with the rare complication of compartment syndrome may help guide investigations and diagnoses of these critically ill patients. PMID- 27688918 TI - Rapidly Progressive Spontaneous Spinal Epidural Abscess. AB - Spinal epidural abscess (SEA) is a rare disease which is often rapidly progressive. Delayed diagnosis of SEA may lead to serious complications and the clinical findings of SEA are generally nonspecific. Paraspinal abscess should be considered in the presence of local low back tenderness, redness, and pain with fever, particularly in children. In case of delayed diagnosis and treatment, SEA may spread to the epidural space and may cause neurological deficits. Magnetic resonance imaging (MRI) remains the method of choice in the diagnosis of SEA. Treatment of SEA often consists of both medical and surgical therapy including drainage with percutaneous entry, corpectomy, and instrumentation. PMID- 27688919 TI - Parkinson's Disease and Cryptogenic Epilepsy. AB - Epilepsy is an uncommon comorbidity of Parkinson's disease (PD) and has been considered not directly associated with PD. We present five patients (3 men and 2 women; ages 49-85) who had concomitant PD and cryptogenic epilepsy. Although rare, epilepsy can coexist with PD and their coexistence may influence the progression of PD. While this may be a chance association, an evolving understanding of the neurophysiological basis of either disease may suggest a mechanistic association. PMID- 27688920 TI - Chemotherapy Used to Halt Lower GI Bleeding in a Rare Case of Metastatic Choriocarcinoma to the GI Tract. AB - Choriocarcinoma, a nonseminomatous germ cell tumor, is a rare type of testicular malignancy that tends to occur in young males. It is, however, exceedingly rare for choriocarcinoma to involve the GI tract. In this article, we present a rare case of a 31-year-old male, diagnosed with choriocarcinoma of the left testes, along with several metastases to distant sites. The patient presented with headaches and severe lower GI bleeding due to metastases to the GI tract, which was eventually controlled with systemic chemotherapy, while requiring several units of packed RBCs during his admission to the hospital. An extensive literature review found very few cases of the occurrence of GI bleeding as a consequence of choriocarcinoma due to metastases to the GI tract. PMID- 27688921 TI - Management of Ankyloglossia and Breastfeeding Difficulties in the Newborn: Breastfeeding Sessions, Myofunctional Therapy, and Frenotomy. AB - The problems of suction in newborns give rise to multiple consequences for both the mother and the newborn. The objective of this paper is to present a case of ankyloglossia ("tongue-tie") and the suction problems that were treated by a multidisciplinary team. The subject is a 17-day-old male patient, with ankyloglossia and suction problems during breastfeeding (pain in the breastfeeding mother, poor weight gain, and long breastfeeds). The patient followed the circuit established in our centre between the services of Oral and Maxillofacial Surgery and Breastfeeding and Speech Therapy and Orofacial Rehabilitation (CELERE). The evolution following the breastfeeding sessions, the myofunctional stimulation, and the lingual frenotomy was very favourable, thereby solving the suction problems that the newborn presented. All our patients receive breastfeeding sessions and myofunctional therapy as treatment. We know that a frenotomy is not always necessary and we believe that the stimulation of sucking before and after the surgical intervention is important in order to improve the final result. PMID- 27688922 TI - Delirious Mania Associated with Autoimmune Gastrothyroidal Syndrome of a Mid-Life Female: The Role of Hashimoto Encephalopathy and a 3-Year Follow-Up including Serum Autoantibody Levels. AB - We report the case study of a 57-year-old Caucasian female with steroid responsive encephalopathy associated with autoimmune thyroiditis (SREAT), commonly termed Hashimoto encephalopathy (HE). This presentation includes one of the longest lasting follow-up studies of HE considering the neuropsychiatric symptoms (here delirium, mania, and EEG-slowing) and their relation to serum autoantibody levels. Antithyroid-peroxidase autoantibodies, the hallmark of autoimmune thyroiditis, were found in the serum and also in the cerebrospinal fluid. Diagnostic analyses found no evidence of limbic encephalopathies characterized by serum antibodies against intracellular, synaptic, or further cell surface antigenic targets, neoplasm, and connective tissue or vasculitis diseases. A potential contribution of bipolar disorder and metabolic encephalopathies due to severe hypothyroidism, glucocorticoid treatment, accelerated thyroid hormone replacement therapy, or vitamin B deficiency is critically discussed. Another special feature of this case report is the linkage of HE to an autoimmune polyendocrine syndrome (type 3B) affecting the gastroduodenum in addition to the thyroid gland. PMID- 27688924 TI - Ischemic Strokes: Observations from a Hospital Based Stroke Registry in Bangladesh. AB - Background. Stroke is an important morbidity for low and middle income countries like Bangladesh. We established the first stroke registry in Bangladesh. Methods. Data was collected from stroke patients who were admitted in Department of Neurology of BIRDEM with first ever stroke, aged between 30 and 90 years. Patients with intracerebral hemorrhage, subarachnoid and subdural hemorrhage, and posttrauma features were excluded. Results. Data was gathered from 679 stroke patients. Mean age was 60.6 years. Almost 68% of patients were male. Small vessel strokes were the most common accounting for 45.4% of all the patients followed by large vessel getting affected in 32.5% of the cases. Only 16 (2.4%) died during treatment, and 436 (64.2%) patients had their mRS score of 3 to 5. Age greater than 70 years was associated with poor outcome on discharge [OR 1.79 (95% CI: 1.05 to 3.06)] adjusting for gender, duration of hospital stay, HDL, and pneumonia. Age, mRS, systolic blood pressure, urinary tract infection, pneumonia, and stroke severity explained the Barthel score. Conclusion. Mortality was low but most of patient had moderate to severe disability at discharge. Age, mRS, systolic blood pressure, urinary tract infection, pneumonia, and stroke severity influenced the Barthel score. PMID- 27688925 TI - Direct Comparison of (19)F qNMR and (1)H qNMR by Characterizing Atorvastatin Calcium Content. AB - Quantitative nuclear magnetic resonance (qNMR) is a powerful tool in measuring drug content because of its high speed, sensitivity, and precision. Most of the reports were based on proton qNMR ((1)H qNMR) and only a few fluorine qNMR ((19)F qNMR) were reported. No research has been conducted to directly compare the advantage and disadvantage between these two methods. In the present study, both (19)F and (1)H qNMR were performed to characterize the content of atorvastatin calcium with the same internal standard. Linearity, precision, and results from two methods were compared. Results showed that (19)F qNMR has similar precision and sensitivity to (1)H qNMR. Both methods generate similar results compared to mass balance method. Major advantage from (19)F qNMR is that the analyte signal is with less or no interference from impurities. (19)F qNMR is an excellent approach to quantify fluorine-containing analytes. PMID- 27688923 TI - Cognitive Training in Parkinson's Disease: A Review of Studies from 2000 to 2014. AB - Cognitive deficits are prevalent among patients with Parkinson's disease (PD), in both early and late stages of the disease. These deficits are associated with lower quality of life, loss of independence, and institutionalization. To date, there is no effective pharmacological treatment for the range of cognitive impairments presented in PD. Cognitive training (CT) has been explored as an alternative approach to remediating cognition in PD. In this review we present a detailed summary of 13 studies of CT that have been conducted between 2000 and 2014 and a critical examination of the evidence for the effectiveness and applicability of CT in PD. Although the evidence shows that CT leads to short term, moderate improvements in some cognitive functions, methodological inconsistencies weaken these results. We discuss several key limitations of the literature to date, propose methods of addressing these questions, and outline the future directions that studies of CT in PD should pursue. Studies need to provide more detail about the cognitive profile of participants, include larger sample sizes, be hypothesis driven, and be clearer about the training interventions and the outcome measures.

AB - The field of pathology has used light microscopy (LM) extensively since the mid 19(th) century for examination of histological tissue preparations. This technology has remained the foremost tool in use by pathologists even as other fields have undergone a great change in recent years through new technologies. However, as new microscopy techniques are perfected and made available, this reliance on the standard LM will likely begin to change. Advanced imaging involving both diffraction-limited and subdiffraction techniques are bringing nondestructive, high-resolution, molecular-level imaging to pathology. Some of these technologies can produce three-dimensional (3D) datasets from sampled tissues. In addition, block-face/tissue-sectioning techniques are already providing automated, large-scale 3D datasets of whole specimens. These datasets allow pathologists to see an entire sample with all of its spatial information intact, and furthermore allow image analysis such as detection, segmentation, and classification, which are impossible in standard LM. It is likely that these technologies herald a major paradigm shift in the field of pathology.

AB - BACKGROUND: Recent developments in molecular pathology and genetic/epigenetic analysis of cancer tissue have resulted in a marked increase in objective and measurable data. In comparison, the traditional morphological analysis approach to pathology diagnosis, which can connect these molecular data and clinical diagnosis, is still mostly subjective. Even though the advent and popularization of digital pathology has provided a boost to computer-aided diagnosis, some important pathological concepts still remain largely non-quantitative and their associated data measurements depend on the pathologist's sense and experience. Such features include pleomorphism and heterogeneity. METHODS AND RESULTS: In this paper, we propose a method for the objective measurement of pleomorphism and heterogeneity, using the cell-level co-occurrence matrix. Our method is based on the widely used Gray-level co-occurrence matrix (GLCM), where relations between neighboring pixel intensity levels are captured into a co-occurrence matrix, followed by the application of analysis functions such as Haralick features. In the pathological tissue image, through image processing techniques, each nucleus can be measured and each nucleus has its own measureable features like nucleus size, roundness, contour length, intra-nucleus texture data (GLCM is one of the methods). In GLCM each nucleus in the tissue image corresponds to one pixel. In this approach the most important point is how to define the neighborhood of each nucleus. We define three types of neighborhoods of a nucleus, then create the co occurrence matrix and apply Haralick feature functions. In each image pleomorphism and heterogeneity are then determined quantitatively. For our method, one pixel corresponds to one nucleus feature, and we therefore named our method Cell Feature Level Co-occurrence Matrix (CFLCM). We tested this method for several nucleus features. CONCLUSION: CFLCM is showed as a useful quantitative method for pleomorphism and heterogeneity on histopathological image analysis.

The visibility of a niche website transforms it into an authority site on a particular "niche of knowledge." This article presents some ways in which a laboratory methodology website can maintain its sustainability. The optimal composition of the website includes a basic content, a blog, and an ancillary part. This article discusses experimenting with the search engine optimization query results page. Strategic placement of keywords and even phrases, as well as fragmentation of the post's material, can improve the website's visibility to search engines. Hyperlinks open a chain reaction of additional links and draw attention to the previous posts. Publications in printed periodicals are a substantial part of a niche website presence on the Internet. Although this article explores a laboratory website on the basis of our hands-on expertise maintaining "Grossing Technology in Surgical Pathology" (www.grossing-technology.com) website with a high volume of traffic for more than a decade, the recommendations presented here for developing an authority website can be applied to other professional specialized websites. The authority websites visibility and sustainability are preconditions for aggregating them in a specialized educational laboratory portal. PMID- 27688929 TI - Antibody-supervised deep learning for quantification of tumor-infiltrating immune cells in hematoxylin and eosin stained breast cancer samples. AB - BACKGROUND: Immune cell infiltration in tumor is an emerging prognostic biomarker in breast cancer. The gold standard for quantification of immune cells in tissue sections is visual assessment through a microscope, which is subjective and semi quantitative. In this study, we propose and evaluate an approach based on antibody-guided annotation and deep learning to quantify immune cell-rich areas in hematoxylin and eosin (H&E) stained samples. METHODS: Consecutive sections of formalin-fixed parafin-embedded samples obtained from the primary tumor of twenty breast cancer patients were cut and stained with H&E and the pan-leukocyte CD45 antibody. The stained slides were digitally scanned, and a training set of immune cell-rich and cell-poor tissue regions was annotated in H&E whole-slide images using the CD45-expression as a guide. In analysis, the images were divided into small homogenous regions, superpixels, from which features were extracted using a pretrained convolutional neural network (CNN) and classified with a support of vector machine. The CNN approach was compared to texture-based classification and to visual assessments performed by two pathologists. RESULTS: In a set of 123,442 labeled superpixels, the CNN approach achieved an F-score of 0.94 (range: 0.92 0.94) in discrimination of immune cell-rich and cell-poor regions, as compared to an F-score of 0.88 (range: 0.87-0.89) obtained with the texture-based classification. When compared to visual assessment of 200 images, an agreement of 90% (kappa = 0.79) to quantify immune infiltration with the CNN approach was achieved while the inter-observer agreement between pathologists was 90% (kappa = 0.78). CONCLUSIONS: Our findings indicate that deep learning can be applied to quantify immune cell infiltration in breast cancer samples using a basic morphology staining only. A good discrimination of immune cell-rich areas was achieved, well in concordance with both leukocyte antigen expression and pathologists' visual assessment.

PMID- 27688931 TI - Rates of provision of clinical information in the skin biopsy requisition form and corresponding encounter visit note. AB - BACKGROUND: The skin biopsy requisition form (RF) serves as a key communication tool for transfer of relevant information related to skin biopsy between clinicians and pathologists. Clinical information in the skin biopsy RF is frequently missing or incomplete. OBJECTIVE: To determine the rates of provision of critical clinical information necessary for histopathologic interpretation in the skin biopsy RF and encounter visit note (EVN). METHODS: A retrospective review of 300 RFs and corresponding EVNs from May 1 to 7, 2012, in a tertiary care dermatology practice. RESULTS: Age (100%), lesion location (100%), and clinical impression (93%) were the most commonly supplied elements in the RF and EVN. Clinical elements that were commonly not provided in the RF but present in the EVN included sampling method - partial versus complete (46%), duration of lesion (54%), morphology of lesion (97%), clinical symptoms (63%), clinical photos (63%), previous clinical (97%), and dermatopathologic diagnoses (82%). LIMITATIONS: Retrospective study design. CONCLUSIONS: These data suggest that while missing critical clinical information in the RF is often present in the EVN, some information is still not present in either source. PMID- 27688932 TI - Unexpected Angiography Findings and Effects on Management. AB - Despite progress in noninvasive imaging with computed tomography and magnetic resonance imaging, conventional angiography still contributes to the diagnostic workup of oncologic and other diseases. Arteriography can reveal tumors not evident on cross-sectional imaging, in addition to defining aberrant or unexpected arterial supply to targeted lesions. This additional and potentially unanticipated information can alter management decisions during interventional procedures. PMID- 27688933 TI - Physical comorbidities increase the risk of psychiatric comorbidity in multiple sclerosis. AB - BACKGROUND: Risk factors for psychiatric comorbidity in multiple sclerosis (MS) are poorly understood. OBJECTIVE: We evaluated the association between physical comorbidity and incident depression, anxiety disorder, and bipolar disorder in a MS population relative to a matched general population cohort. METHODS: Using population-based administrative data from Alberta, Canada we identified 9624 persons with MS, and 41,194 matches. Using validated case definitions, we estimated the incidence of depression, anxiety disorder, and bipolar disorder, and their association with physical comorbidities using Cox regression, adjusting for age, sex, socioeconomic status, and index year. RESULTS: In both populations, men had a lower risk of depression and anxiety disorders than women, as did individuals who were >=45 years versus <45 years at the index date. The risk of bipolar disorder declined with increasing age. The risks of incident depression (HR 1.92; 1.82-2.04), anxiety disorders (HR 1.52; 1.42-1.63), and bipolar disorder (HR 2.67; 2.29-3.11) were higher in the MS population than the matched population. These associations persisted essentially unchanged after adjustment for covariates including physical comorbidities. Multiple physical comorbidities were associated with psychiatric disorders in both populations. CONCLUSION: Persons with MS are at increased risk of psychiatric comorbidity generally, and some physical comorbidities are associated with additional risk. PMID- 27688935 TI - A review of novel analytical diagnostics for liquid biopsies: spectroscopic and spectrometric serum profiling of primary and secondary brain tumors. AB - INTRODUCTION: Spectroscopic and spectrometric analysis of biological samples is regarded as quick, cost effective, easy to operate, and spectroscopic sample preparation involves minimal sample preparation. RESULTS: Techniques like infrared (IR) spectroscopy, surface-enhanced laser desorption/ionization (SELDI) mass spectroscopy (MS), and matrix-assisted laser desorption/ionization (MALDI) MS could enable early diagnosis of cancer, disease monitoring, and assessment of treatment responses allowing refinement, if required. DISCUSSION: Carrying out analytical testing within outpatient clinics would dramatically cut the time spent by patients attending different appointments, at different locations, save hospital time and resources but importantly would theoretically enable a reduction in mortality and morbidity. While the advantages of such a prospect seem obvious, this review aims to evaluate the use of human serum spectroscopic and spectrometric analysis as a diagnostic tool for brain cancers, creating a platform for the future of cancer diagnostics. PMID- 27688936 TI - Review of clinical studies of perampanel in adolescent patients. AB - AIM: To assess the clinical trial and real-world data for adjunctive perampanel in adolescents and develop consensus recommendations to guide the use of perampanel in this population in clinical practice. METHODS: In May 2015, 15 epilepsy experts attended a Consensus Development Meeting to assess the clinical trial data for perampanel, specific to the adolescent age group (12-17 years) and develop consensus treatment recommendations. RESULTS AND DISCUSSION: Analysis of the adolescent subgroup data of three pivotal placebo-controlled, double-blind, phase 3 trials investigating perampanel in patients with ongoing focal epileptic seizures despite receiving one to three antiepileptic drugs found that perampanel 4-12 mg was superior to placebo. The tolerability profile of perampanel was generally acceptable. Adolescent patients receiving long-term treatment with perampanel in an open-label extension study maintained improvements in seizure control compared with baseline, with a favorable risk-benefit profile. A phase 2 study showed that perampanel had no clinically important effects on cognitive function, growth, and development. CONCLUSION: Perampanel is a welcome addition to the armamentarium of existing antiepileptic drugs as it represents a new approach in the management of epilepsy, with a novel mechanism of action, and the potential to have a considerable impact on the treatment of adolescents with epilepsy. PMID- 27688934 TI - Dominant hemisphere functional networks compensate for structural connectivity loss to preserve phonological retrieval with aging. AB - INTRODUCTION: Loss of hemispheric asymmetry during cognitive tasks has been previously demonstrated in the literature. In the context of language, increased right hemisphere activation is observed with aging. Whether this relates to compensation to preserve cognitive function or dedifferentiation implying loss of hemispheric specificity without functional consequence, remains unclear. METHODS: With a multifaceted approach, integrating structural and functional imaging data during a word retrieval task, in a group of younger and older adults with equivalent cognitive performance, we aimed to establish whether interactions between hemispheres or reorganization of dominant hemisphere networks preserve function. We examined functional and structural connectivity on data from our previously published functional activation study. Functional connectivity was measured using psychophysiological interactions analysis from the left inferior frontal gyrus (LIFG) and the left insula (LINS), based on published literature, and the right inferior frontal gyrus (RIFG) based on our previous study. RESULTS: Although RIFG showed increased activation, its connectivity decreased with age. Meanwhile, LIFG and LINS connected more bilaterally in the older adults. White matter integrity, measured by fractional anisotropy (FA) from diffusion tensor imaging, decreased significantly in the older group. Importantly, LINS functional connectivity to LIFG correlated inversely with FA. CONCLUSIONS: We demonstrate that left hemispheric language areas show higher functional connectivity in older adults with intact behavioral performance, and thus, may have a role in preserving function. The inverse correlation of functional and structural connectivity with age is in keeping with emerging literature and merits further investigation with tractography studies and in other cognitive domains. PMID- 27688937 TI - The anterior versus posterior hippocampal oscillations debate in human spatial navigation: evidence from an electrocorticographic case study. AB - INTRODUCTION: Hippocampal oscillations have been regularly described as playing a dominant role in spatial memory and navigation in rodents. In humans, the relative role of anterior versus posterior rhythms during navigational memory is not established. METHODS: Here, we tested this hypothesis using direct brain ECoG recordings in the anterior and posterior hippocampus of a patient, in a navigational task requiring spatial memory. We assessed multiple oscillatory bands during encoding and retrieval phases. RESULTS: We found navigation related 1-3.5 Hz activity during retrieval, both in the anterior and posterior hippocampus. Activity between 4 and 8 Hz was identified during both encoding and retrieval, only in the anterior hippocampus. CONCLUSIONS: Our findings are consistent with the view that an anterior/posterior functional gradient is present in the hippocampus, and involves two distinct neuronal networks, supporting either encoding or retrieval processes. Although this is a single case scenario, these findings suggest that neural oscillations during spatial navigation do vary across hippocampal subregions, as a function of encoding versus retrieval processes during the mnemonic process. In this single case study, the results point to the presence of a dual involvement of multiple frequency bands across hippocampal subregions during encoding and retrieval. Although these results need generalization, they provide a new perspective on distinct physiological properties of the anterior and posterior hippocampus in human spatial navigation during encoding and retrieval. PMID- 27688938 TI - Reduced specialized processing in psychotic disorder: a graph theoretical analysis of cerebral functional connectivity. AB - BACKGROUND: Previous research has shown that the human brain can be represented as a complex functional network that is characterized by specific topological properties, such as clustering coefficient, characteristic path length, and global/local efficiency. Patients with psychotic disorder may have alterations in these properties with respect to controls, indicating altered efficiency of network organization. This study examined graph theoretical changes in relation to differential genetic risk for the disorder and aimed to identify clinical correlates. METHODS: Anatomical and resting-state MRI brain scans were obtained from 73 patients with psychotic disorder, 83 unaffected siblings, and 72 controls. Topological measures (i.e., clustering coefficient, characteristic path length, and small-worldness) were used as dependent variables in a multilevel random regression analysis to investigate group differences. In addition, associations with (subclinical) psychotic/cognitive symptoms were examined. RESULTS: Patients had a significantly lower clustering coefficient compared to siblings and controls, with no difference between the latter groups. No group differences were observed for characteristic path length and small-worldness. None of the topological properties were associated with (sub)clinical psychotic and cognitive symptoms. CONCLUSIONS: The reduced ability for specialized processing (reflected by a lower clustering coefficient) within highly interconnected brain regions observed in the patient group may indicate state related network alterations. There was no evidence for an intermediate phenotype and no evidence for psychopathology-related alterations. PMID- 27688939 TI - A multi-biomarker follow-up study of patients with multiple sclerosis. AB - OBJECTIVES: This study aimed to examine the levels of the macrophage marker sCD163 and other biomarkers at the time of diagnosis of patients with either clinically isolated syndrome (CIS) or relapsing-remitting multiple sclerosis (RRMS), and assess relation to clinical indicators of prognosis, disease activity (DA), and changes in the levels of these biomarkers at follow-up. MATERIALS AND METHODS: The clinical status and MRI were reevaluated in 56 patients more than 1 year after diagnosis with a median follow-up time of 2 years. Levels of biomarkers in serum and cerebrospinal fluid (CSF) samples were evaluated by enzyme-linked immunosorbent assays. RESULTS: There was no significant difference in time to DA between patients with CIS and RRMS. A high sCD163 ratio (>0.07) was significantly (P = 0.04) associated with time to DA in the untreated patient group. In 21 patients reevaluated with serum and CSF samples, the sCD163 ratio levels decreased from 0.068 to 0.054 (P = 0.026) in the CIS/RRMS-treated group. The CSF CXCL13, CXCL13 ratio, CSF neurofilament light polypeptide and osteopontin levels also decreased significantly in the CIS/RRMS-treated group. CONCLUSIONS: The levels of all biomarkers changed concurrently with MS treatment. The sCD163 ratio was identified as a potential novel marker for time to DA. PMID- 27688940 TI - CBT reduces CBF: cognitive-behavioral therapy reduces cerebral blood flow in fear relevant brain regions in spider phobia. AB - BACKGROUND: Imaging studies have provided evidence that cognitive-behavioral therapy (CBT) is able to change brain activation in phobic patients in response to threatening stimuli. The changes occurred in both emotion-generating and modulatory regions. In this study, we use a data-driven approach to explore resting state cerebral blood flow (CBF) measured by arterial spin labeling (ASL), before and after CBT. METHODS: Eight female patients with spider phobia were scanned before and 1 month after an exposure-based group therapy for spider phobia. Each MRI session consisted of an ASL resting state measurement acquired before and after a symptom provocation task involving the showing of spider pictures in the scanner. The first ASL acquisition measured anticipatory anxiety and the second measured postprocessing of phobia-relevant stimuli. RESULTS: Cognitive-behavioral therapy significantly reduced spider phobic symptoms in all patients. Symptom reduction during anticipatory anxiety was accompanied by reduced bilateral CBF in the parahippocampal gyrus, ventral anterior thalamus, Brodmann area 8, and the anterior cingulate cortex. During postprocessing of phobia-relevant stimuli, patients showed reduced CBF in the bilateral insula, components of the motor cortex, and areas associated with language functions. CONCLUSIONS: Longitudinal CBF dynamics following CBT were in concordance with results from several studies using BOLD fMRI to investigate the effects of psychotherapy on brain activity. CBF can be quantified by ASL, with the principal advantage of sensitivity to slow variations in neural activity and task independence. Therefore, ASL may be a suitable method for monitoring and evaluating the efficacy of psychotherapy or pharmacotherapy approaches. PMID- 27688941 TI - Long-term acclimatization to high-altitude hypoxia modifies interhemispheric functional and structural connectivity in the adult brain. AB - BACKGROUND: Structural and functional networks can be reorganized to adjust to environmental pressures and physiologic changes in the adult brain, but such processes remain unclear in prolonged adaptation to high-altitude (HA) hypoxia. This study aimed to characterize the interhemispheric functionally and structurally coupled modifications in the brains of adult HA immigrants. METHODS: We performed resting-state functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) in 16 adults who had immigrated to the Qinghai Tibet Plateau (2300-4400 m) for 2 years and in 16 age-matched sea-level (SL) controls. A recently validated approach of voxel-mirrored homotopic connectivity (VMHC) was employed to examine the interhemispheric resting-state functional connectivity. Areas showing changed VMHC in HA immigrants were selected as regions of interest for follow-up DTI tractography analysis. The fiber parameters of fractional anisotropy and fiber length were obtained. Cognitive and physiological assessments were made and correlated with the resulting image metrics. RESULTS: Compared with SL controls, VMHC in the bilateral visual cortex was significantly increased in HA immigrants. The mean VMHC value extracted within the visual cortex was positively correlated with hemoglobin concentration. Moreover, the path length of the commissural fibers connecting homotopic visual areas was increased in HA immigrants, covarying positively with VMHC. CONCLUSIONS: These observations are the first to demonstrate interhemispheric functional and structural connectivity resilience in the adult brain after prolonged HA acclimatization independent of inherited and developmental effects, and the coupled modifications in the bilateral visual cortex indicate important neural compensatory mechanisms underlying visual dysfunction in physiologically well-acclimatized HA immigrants. The study of human central adaptation to extreme environments promotes the understanding of our brain's capacity for survival. PMID- 27688942 TI - Collateral state and the effect of endovascular reperfusion therapy on clinical outcome in ischemic stroke patients. AB - PURPOSE: Clinically successful endovascular therapy (EVT) in ischemic stroke requires reliable noninvasive pretherapeutic selection criteria. We investigated the association of imaging parameters including CT angiographic collaterals and degree of reperfusion with clinical outcome after EVT. METHODS: In our database, we identified 93 patients with large vessel occlusion in the anterior circulation treated with EVT. Besides clinical data, we assessed the baseline Alberta Stroke Program Early CT score (ASPECTS) on noncontrast CT (NCCT) and CT angiography (CTA) source images, collaterals (CT-CS) and clot burden score (CBS) on CTA and the degree of reperfusion after EVT on angiography. Three readers, blinded to clinical information, evaluated the images in consensus. Data-driven multivariable ordinal regression analysis identified predictors of good outcome after 90 days as measured with the modified Rankin Scale. RESULTS: Successful angiographic reperfusion (OR 26.50; 95%-CI 9.33-83.61) and good collaterals (OR 9.69; 95%-CI 2.28-59.27) were independent predictors of favorable outcome along with female sex (OR 0.35; 95%-CI 0.14-0.85), younger age (OR 0.88; 95%-CI 0.83 0.92) and higher NCCT ASPECTS (OR 2.54; 95%-CI 1.01-6.63). Outcome was best in patients with good collaterals and successful reperfusion, but there was no statistical interaction between collaterals and reperfusion. CONCLUSIONS: CTA collateral status was the strongest pretherapeutic predictor of favorable outcome in ischemic stroke patients treated with EVT. CTA-collaterals are thus well suited for patient selection in EVT. However, the independent effect of reperfusion on outcome tended to be stronger than that of CTA-collaterals. PMID- 27688943 TI - Early-life single-episode sevoflurane exposure impairs social behavior and cognition later in life. AB - BACKGROUND: Single-episode anesthetic exposure is the most prevalent surgery related incidence among young children in the United States. Although numerous studies have used animals to model the effects of neonatal anesthetics on behavioral changes later on in life, our understanding of the functional consequences to the developing brain in a comprehensive and clinically relevant manner is unclear. METHODS: The volatile anesthetic, sevoflurane (sevo) was administered to C57BL6 postnatal day 7 (P7) mice in a 40% oxygen and 60% nitrogen gas mixture. In order to examine the effects of sevo alone on the developing brain in a clinically relevant manner, mice were exposed to an average of 2.38 +/ 0.11% sevo for 2 h. No sevo (control) mice were treated in an identical manner without sevo exposure. Mice were examined for cognition and neuropsychiatric-like behavioral changes at 1-5 months of age. RESULTS: Using the active place avoidance (APA) test and the novel object recognition (NOR) test, we demonstrated that P7 sevo-treated mice showed a deficit in learning and memory both during periadolescence and adulthood. We then employed a battery of neuropsychiatric like behavioral tests to examine social interaction, communication, and repetitive behavior. Interestingly, compared to the no-sevo-treated group, sevo treated mice showed significant reductions in the time interacting with a novel mouse (push-crawl and following), time and interaction in a chamber with a novel mouse, and time sniffing a novel social odor. CONCLUSIONS: Our study established that single-episode, 2-h sevo treatment during early life impairs cognition later on in life. With this approach, we also observed neuropsychiatric-like behavior changes such as social interaction deficits in the sevo-treated mice. This study elucidated the effects of a clinically relevant single-episode sevo application, given during the neonatal period, on neurodevelopmental behavioral changes later on in life. PMID- 27688944 TI - Reliable measurements of brain atrophy in individual patients with multiple sclerosis. AB - INTRODUCTION: As neurodegeneration is recognized as a major contributor to disability in multiple sclerosis (MS), brain atrophy quantification could have a high added value in clinical practice to assess treatment efficacy and disease progression, provided that it has a sufficiently low measurement error to draw meaningful conclusions for an individual patient. METHOD: In this paper, we present an automated longitudinal method based on Jacobian integration for measuring whole-brain and gray matter atrophy based on anatomical magnetic resonance images (MRI), named MSmetrix. MSmetrix is specifically designed to measure atrophy in patients with MS, by including iterative lesion segmentation and lesion filling based on FLAIR and T1-weighted MRI scans. RESULTS: MS metrix is compared with SIENA with respect to test-retest error and consistency, resulting in an average test-retest error on an MS data set of 0.13% (MS metrix) and 0.17% (SIENA) and a consistency error of 0.07% (MS metrix) and 0.05% (SIENA). On a healthy subject data set including physiological variability the test-retest is 0.19% (MS metrix) and 0.31% (SIENA). CONCLUSION: Therefore, we can conclude that MSmetrix could be of added value in clinical practice for the follow-up of treatment and disease progression in MS patients.

AB - BACKGROUND: Positron Emission Tomography (PET) is traditionally used to image patients in restrictive positions, with few devices allowing for upright, brain dedicated imaging. Our team has explored the concept of wearable PET imagers which could provide functional brain imaging of freely moving subjects. To test feasibility and determine future considerations for development, we built a rudimentary proof-of-concept prototype (Helmet_PET) and conducted tests in phantoms and four human volunteers. METHODS: Twelve Silicon Photomultiplier-based detectors were assembled in a ring with exterior weight support and an interior mechanism that could be adjustably fitted to the head. We conducted brain phantom tests as well as scanned four patients scheduled for diagnostic F(18-) FDG PET/CT imaging. For human subjects the imager was angled such that field of view included basal ganglia and visual cortex to test for typical resting-state pattern. Imaging in two subjects was performed ~4 hr after PET/CT imaging to simulate lower injected F(18-) FDG dose by taking advantage of the natural radioactive decay of the tracer (F(18) half-life of 110 min), with an estimated imaging dosage of 25% of the standard. RESULTS: We found that imaging with a simple lightweight ring of detectors was feasible using a fraction of the standard radioligand dose. Activity levels in the human participants were quantitatively similar to standard PET in a set of anatomical ROIs. Typical resting-state brain pattern activation was demonstrated even in a 1 min scan of active head rotation. CONCLUSION: To our knowledge, this is the first demonstration of imaging a human subject with a novel wearable PET imager that moves with robust head movements. We discuss potential research and clinical applications that will drive the design of a fully functional device. Designs will need to consider trade-offs between a low weight device with high mobility and a heavier device with greater sensitivity and larger field of view. PMID- 27688945 TI - Kappa-opioid receptors differentially regulate low and high levels of ethanol intake in female mice. AB - INTRODUCTION: Studies in laboratory animals and humans indicate that endogenous opioids play an important role in regulating the rewarding value of various drugs, including ethanol (EtOH). Indeed, opioid antagonists are currently a front line treatment for alcoholism in humans. Although roles for mu- and delta-opioid receptors have been characterized, the contribution of kappa-opioid receptors (KORs) is less clear. There is evidence that changes in KOR system function can decrease or increase EtOH drinking, depending on test conditions. For example, female mice lacking preprodynorphin - the precursor to the endogenous KOR ligand dynorphin - have reduced EtOH intake. Considering that KORs can regulate dopamine (DA) transmission, we hypothesized that KORs expressed on DA neurons would play a prominent role in EtOH intake in females. METHODS: We used a Cre/loxP recombination strategy to ablate KORs throughout the body or specifically on dopamine uptake transporter (DAT)-expressing neurons to investigate the role of KORs on preference for and intake of EtOH (2-bottle choice), the transition from moderate to excessive EtOH drinking (intermittent EtOH access), and binge EtOH drinking (drinking in the dark [DID]). RESULTS: KOR deletion decreased preference for EtOH, although this effect was less pronounced when EtOH intake increased beyond relatively low levels. DISCUSSION: Our findings indicate that KOR activation increases EtOH drinking via effects mediated, at least in part, by KORs on DA neurons. While the mechanisms of this regulation remain unknown, previous work suggests that alterations in negative reinforcement processes or sensitivity to the sensory properties of EtOH can affect preference and intake.

AB - Head injuries are a particular concern in Hawai'i given the large military population, the presence of many land and water sports such as football and surfing, and the lenient helmet laws for motorcycle and bicycle riders. Physical, psychological, and cognitive symptoms from single or repeated concussions can affect an individual's reentry to society and activity. Current literature indicates that repeated head injuries are associated with chronic traumatic encephalopathy (CTE) which is thought to lead to dementia. This paper reviews literature discussing causes of concussion including its incidence and prevalence in Hawai'i. Furthermore, the neurophysiological and neurobiological etiologies are discussed followed by an overview of methods for identification and management of concussion. The paper serves as information for professionals in the community such as educators, military personnel, and healthcare workers to identify risks of concussion, management of symptoms, and to connect with resources and programs available in Hawai'i. PMID- 27688952 TI - Self-Reported Experiences of Discrimination and Depression in Native Hawaiians. AB - Discrimination is an acute and chronic stressor that negatively impacts the health of many ethnic groups in the United States. Individuals who perceive increased levels of discrimination are at risk of experiencing psychological distress and symptoms of depression. No study to date has examined the relationship between perceived discrimination and mental health in Native Hawaiians. The purpose of this study is to explore the relationship between perceived discrimination and depression based on the Homestead Health Survey mailed to Native Hawaiian residents of Hawaiian Home Lands. This study also explores the role of cultural identity and how it may impact experiences of discrimination and symptoms of depression. Based on cross-sectional data obtained from 104 Native Hawaiian residents, a significant positive correlation was found between perceived discrimination and symptoms of depression (r= 0.32, P<.001). Cultural identity did not significantly correlate with discrimination or depression. Multiple linear regression analyses indicate that the relationship between depression and discrimination remained statistically significant (coefficient estimate of 0.18; P<.01), after accounting for differences in socio demographics and degree of identification with the Native Hawaiian and American cultures. These findings are consistent with other studies that have focused on the effects of discrimination on psychological wellbeing for other ethnic minority populations.

PMID- 27688953 TI - Recovery of Left Ventricular Function After Percutaneous Coronary Intervention Compared to Coronary Artery Bypass Grafting in Patients with Multi-Vessel Coronary Disease and Left Ventricular Dysfunction. AB - Recovery of left ventricular (LV) function after revascularization has been described for coronary artery bypass grafting (CABG); however, LV recovery after percutaneous coronary intervention (PCI), and how it compares to CABG has not been well described in the literature. The aim of this single center retrospective study was to evaluate LV recovery in patients with severely reduced LV function undergoing PCI compared to those undergoing CABG. Patients with LV ejection fraction (LVEF) < 40% and multivessel coronary artery disease (CAD) undergoing revascularization with either CABG (n=16) or PCI (n=176), and with 12 months of follow up data were included in the study. LVEF at baseline exhibited significant differences between PCI (28.5 +/- 8.0) and CABG (24.2 +/- 6.8) groups (P=.05). LVEF recovery at 6-month follow up showed no difference between PCI and CABG groups. LVEF recovery differences at one-year follow-up was significantly different between PCI (4.82) and CABG (15.25) groups (P=.005). Patients with severely reduced LV function undergoing multivessel PCI had a statistically significant increase in LVEF over time; however patients undergoing CABG demonstrated greater gains in LVEF over the same time period. Surgical revascularization with CABG may be a procedure of choice in patients with depressed LV function and multivessel CAD.

AB - Hawai'i had high insurance coverage rates even before the Affordable Health Care Act and continues to have a high percentage of the population with health insurance today. However, high insurance rates can disguise wide variation in what is covered and what it costs. In this essay, an Australian Masters in Public Health student from the University of Hawai'i considers the strengths and weaknesses of insurance coverage in the US health-care system when her friend "Peter" becomes seriously ill. PMID- 27688957 TI - Are sites with multiple single nucleotide variants in cancer genomes a consequence of drivers, hypermutable sites or sequencing errors? AB - Across independent cancer genomes it has been observed that some sites have been recurrently hit by single nucleotide variants (SNVs). Such recurrently hit sites might be either (i) drivers of cancer that are postively selected during oncogenesis, (ii) due to mutation rate variation, or (iii) due to sequencing and assembly errors. We have investigated the cause of recurrently hit sites in a dataset of >3 million SNVs from 507 complete cancer genome sequences. We find evidence that many sites have been hit significantly more often than one would expect by chance, even taking into account the effect of the adjacent nucleotides on the rate of mutation. We find that the density of these recurrently hit sites is higher in non-coding than coding DNA and hence conclude that most of them are unlikely to be drivers. We also find that most of them are found in parts of the genome that are not uniquely mappable and hence are likely to be due to mapping errors. In support of the error hypothesis, we find that recurently hit sites are not randomly distributed across sequences from different laboratories. We fit a model to the data in which the rate of mutation is constant across sites but the rate of error varies. This model suggests that ~4% of all SNVs are errors in this dataset, but that the rate of error varies by thousands-of-fold between sites. PMID- 27688959 TI - Polymorphic DNA microsatellite markers for forensic individual identification and parentage analyses of seven threatened species of parrots (family Psittacidae). AB - The parrot family represents one of the bird group with the largest number of endangered species, as a result of habitat destruction and illegal trade. This illicit traffic involves the smuggling of eggs and animals, and the laundering through captive breeding facilities of wild-caught animals. Despite the huge potential of wildlife DNA forensics to determine with conclusive evidence illegal trade, current usage of DNA profiling approaches in parrots has been limited by the lack of suitable molecular markers specifically developed for the focal species and by low cross-species polymorphism. In this study, we isolated DNA microsatellite markers in seven parrot species threatened with extinction (Amazona brasiliensis, A. oratrix, A. pretrei, A. rhodocorytha, Anodorhynchus leari, Ara rubrogenys and Primolius couloni). From an enriched genomic library followed by 454 pyrosequencing, we characterized a total of 106 polymorphic microsatellite markers (mostly tetranucleotides) in the seven species and tested them across an average number of 19 individuals per species. The mean number of alleles per species and across loci varied from 6.4 to 8.3, with the mean observed heterozygosities ranging from 0.65 to 0.84. Identity and parentage exclusion probabilities were highly discriminatory. The high variability displayed by these microsatellite loci demonstrates their potential utility to perform individual genotyping and parentage analyses, in order to develop a DNA testing framework to determine illegal traffic in these threatened species. PMID- 27688958 TI - Contributions to the functional morphology of caudate skulls: kinetic and akinetic forms. AB - A strongly ossified and rigid skull roof, which prevents parietal kinesis, has been reported for the adults of all amphibian clades. Our MU-CT investigations revealed that the Buresch's newt (Triturus ivanbureschi) possess a peculiar cranial construction. In addition to the typical amphibian pleurokinetic articulation between skull roof and palatoquadrate associated structures, we found flexible connections between nasals and frontals (prokinesis), vomer and parasphenoid (palatokinesis), and between frontals and parietals (mesokinesis). This is the first description of mesokinesis in urodelans. The construction of the skull in the Buresch's newts also indicates the presence of an articulation between parietals and the exocipitals, discussed as a possible kind of metakinesis. The specific combination of pleuro-, pro-, meso-, palato-, and metakinetic skull articulations indicate to a new kind of kinetic systems unknown for urodelans to this date. We discuss the possible neotenic origin of the skull kinesis and pose the hypothesis that the kinesis in T. ivanbureschi increases the efficiency of fast jaw closure. For that, we compared the construction of the skull in T. ivanbureschi to the akinetic skull of the Common fire salamander Salamandra salamandra. We hypothesize that the design of the skull in the purely terrestrial living salamander shows a similar degree of intracranial mobility. However, this mobility is permitted by elasticity of some bones and not by true articulation between them. We comment on the possible relation between the skull construction and the form of prey shaking mechanism that the species apply to immobilize their victims. PMID- 27688960 TI - Parameter estimation in tree graph metabolic networks. AB - We study the glycosylation processes that convert initially toxic substrates to nutritionally valuable metabolites in the flavonoid biosynthesis pathway of tomato (Solanum lycopersicum) seedlings. To estimate the reaction rates we use ordinary differential equations (ODEs) to model the enzyme kinetics. A popular choice is to use a system of linear ODEs with constant kinetic rates or to use Michaelis-Menten kinetics. In reality, the catalytic rates, which are affected among other factors by kinetic constants and enzyme concentrations, are changing in time and with the approaches just mentioned, this phenomenon cannot be described. Another problem is that, in general these kinetic coefficients are not always identifiable. A third problem is that, it is not precisely known which enzymes are catalyzing the observed glycosylation processes. With several hundred potential gene candidates, experimental validation using purified target proteins is expensive and time consuming. We aim at reducing this task via mathematical modeling to allow for the pre-selection of most potential gene candidates. In this article we discuss a fast and relatively simple approach to estimate time varying kinetic rates, with three favorable properties: firstly, it allows for identifiable estimation of time dependent parameters in networks with a tree-like structure. Secondly, it is relatively fast compared to usually applied methods that estimate the model derivatives together with the network parameters. Thirdly, by combining the metabolite concentration data with a corresponding microarray data, it can help in detecting the genes related to the enzymatic processes. By comparing the estimated time dynamics of the catalytic rates with time series gene expression data we may assess potential candidate genes behind enzymatic reactions. As an example, we show how to apply this method to select prominent glycosyltransferase genes in tomato seedlings. PMID- 27688961 TI - In situ visualization of bacterial populations in coral tissues: pitfalls and solutions. AB - In situ visualization of microbial communities within their natural habitats provides a powerful approach to explore complex interactions between microorganisms and their macroscopic hosts. Specifically, the application of fluorescence in situ hybridization (FISH) to simultaneously identify and visualize diverse microbial taxa associated with coral hosts, including symbiotic algae (Symbiodinium), Bacteria, Archaea, Fungi and protists, could help untangle the structure and function of these diverse taxa within the coral holobiont. However, the application of FISH approaches to coral samples is constrained by non-specific binding of targeted rRNA probes to cellular structures within the coral animal tissues (including nematocysts, spirocysts, granular gland cells within the gastrodermis and cnidoglandular bands of mesenterial filaments). This issue, combined with high auto-fluorescence of both host tissues and endosymbiotic dinoflagellates (Symbiodinium), make FISH approaches for analyses of coral tissues challenging. Here we outline the major pitfalls associated with applying FISH to coral samples and describe approaches to overcome these challenges. PMID- 27688963 TI - A comparison between traditional and measurement-error growth models for weakfish Cynoscion regalis. AB - Inferring growth for aquatic species is dependent upon accurate descriptions of age-length relationships, which may be degraded by measurement error in observed ages. Ageing error arises from biased and/or imprecise age determinations as a consequence of misinterpretation by readers or inability of ageing structures to accurately reflect true age. A Bayesian errors-in-variables (EIV) approach (i.e., measurement-error modeling) can account for ageing uncertainty during nonlinear growth curve estimation by allowing observed ages to be parametrically modeled as random deviates. Information on the latent age composition then comes from the specified prior distribution, which represents the true age structure of the sampled fish population. In this study, weakfish growth was modeled by means of traditional and measurement-error von Bertalanffy growth curves using otolith- or scale-estimated ages. Age determinations were assumed to be log-normally distributed, thereby incorporating multiplicative error with respect to ageing uncertainty. The prior distribution for true age was assumed to be uniformly distributed between +/-4 of the observed age (yr) for each individual. Measurement-error growth models described weakfish that reached larger sizes but at slower rates, with median length-at-age being overestimated by traditional growth curves for the observed age range. In addition, measurement-error models produced slightly narrower credible intervals for parameters of the von Bertalanffy growth function, which may be an artifact of the specified prior distributions. Subjectivity is always apparent in the ageing of fishes and it is recommended that measurement-error growth models be used in conjunction with otolith-estimated ages to accurately capture the age-length relationship that is subsequently used in fisheries stock assessment and management. PMID- 27688962 TI - Environment and host species shape the skin microbiome of captive neotropical bats. AB - BACKGROUND: A wide range of microorganisms inhabit animal skin. This microbial community (microbiome) plays an important role in host defense against pathogens and disease. Bats (Chiroptera: Mammalia) are an ecologically and evolutionarily diversified group with a relatively unexplored skin microbiome. The bat skin microbiome could play a role in disease resistance, for example, to white nose syndrome (WNS), an infection which has been devastating North American bat populations. However, fundamental knowledge of the bat skin microbiome is needed before understanding its role in health and disease resistance. Captive neotropical frugivorous bats Artibeus jamaicensis and Carollia perspicillataprovide a simple controlled system in which to characterize the factors shaping the bat microbiome. Here, we aimed to determine the relative importance of habitat and host species on the bat skin microbiome. METHODS: We performed high-throughput 16S rRNA gene sequencing of the skin microbiome of two different bat species living in captivity in two different habitats. In the first habitat, A. jamaicensis and C. perspicillata lived together, while the second habitat contained only A. jamaicensis. RESULTS: We found that both habitat and host species shape the composition and diversity of the skin microbiome, with habitat having the strongest influence. Cohabitating A. jamaicensis and C. perspicillata shared more similar skin microbiomes than members of the same species (A. jamaicensis) across two habitats. DISCUSSION: These results suggest that in captivity, the skin microbial community is homogenised by the shared environments and individual proximities of bats living together in the same habitat, at the expense of the innate host species factors. The predominant influence of habitat suggests that environmental microorganisms or pathogens might colonize bat skin. We also propose that bat populations could differ in pathogen susceptibility depending on their immediate environment and habitat. PMID- 27688964 TI - Successful population establishment from small introductions appears to be less common than believed. AB - Although small populations are at high risk of extinction, there are regular reports in the scientific literature of purported small, isolated, persistent populations. One source of evidence of the viability of small populations comes from the alleged successful introduction of species to areas outside their original range from introductions of few individuals. We reviewed the examples from introduction compendia on deliberate translocations of birds, and the original sources, to identify and evaluate purported examples of successful establishments from small introductions. We found 23 purportedly successful introductions from few (<30) individuals. After assessing original sources, we found that two of the claims were substantiated; the rest were ambiguous or could be rejected as examples, primarily due to a lack of evidence in original sources of the number of birds released and because of supplemental individuals from other releases, releases in nearby regions, and the possibility of natural invasion. Our results suggest that reports of successful establishment of birds from introductions of few individuals have been overstated. These results strengthen the relationship previously reported between propagule pressure and likelihood of establishment, and support the lack of viability of small populations presumed by population theory. We suggest that analyses of introduction failure and success would benefit from excluding studies where introduction effort is unknown or unreliably documented. PMID- 27688966 TI - In vitro and in vivo comparison of transport media for detecting nasopharyngeal carriage of Streptococcus pneumoniae. AB - BACKGROUND: As a standard method for pneumococcal carriage studies, the World Health Organization recommends nasopharyngeal swabs be transported and stored at cool temperatures in a medium containing skim-milk, tryptone, glucose and glycerol (STGG). An enrichment broth used for transport at room temperature in three carriage studies performed in Norway may have a higher sensitivity than STGG. We therefore compared the media in vitro and in vivo. METHODS: For the in vitro component, three strains (serotype 4, 19F and 3) were suspended in STGG and enrichment broth. Recovery was compared using latex agglutination, quantification of bacterial loads by real-time PCR of the lytA gene, and counting colonies from incubated plates. For the in vivo comparison, paired swabs were obtained from 100 children and transported in STGG at cool temperatures or in enrichment broth at room temperature. Carriage was identified by latex agglutination and confirmed by Quellung reaction. RESULTS: In vitro, the cycle threshold values obtained by PCR did not differ between the two media (p = 0.853) and no clear difference in colony counts was apparent after incubation (p = 0.593). In vivo, pneumococci were recovered in 46% of swabs transported in STGG and 51% of those transported in enrichment broth (Kappa statistic 0.90, p = 0.063). DISCUSSION: Overall, no statistical differences in sensitivity were found between STGG and enrichment broth. Nevertheless, some serotype differences were observed and STGG appeared slightly less sensitive than enrichment broth for detection of nasopharyngeal carriage of pneumococci by culturing. We recommend the continued use of STGG for transport and storage of nasopharyngeal swabs in pneumococcal carriage studies for the benefit of comparability between studies and settings, including more resource-limited settings. PMID- 27688965 TI - Short-term MRI measurements as predictors of EDSS progression in relapsing remitting multiple sclerosis: grey matter atrophy but not lesions are predictive in a real-life setting. AB - BACKGROUND: Magnetic resonance imaging (MRI) is the best biomarker of inflammatory disease activity in relapsing remitting Multiple Sclerosis (RRMS) so far but the association with disability is weak. Appearance of new MRI-lesions is used to evaluate response to immunotherapies in individual patients as well as being the most common primary outcome in phase-2 trials. Measurements of brain atrophy show promising outcomes in natural cohort studies and some phase-2 trials. From a theoretical perspective they might represent irreversible neurodegeneration and be more closely associated with disability. However, these atrophy measurements are not yet established as prognostic factors in real-life clinical routine. High field MRI has improved image quality and resolution and new methods to measure atrophy dynamics have become available. OBJECTIVE: To investigate the predictive value of MRI classification criteria in to high/low atrophy and inflammation groups, and to explore predictive capacity of two consecutive routine MRI scans for disability progression in RRMS in a real-life prospective cohort. METHODS: 82 RRMS-patients (40 untreated, 42 treated with immunotherapies, mean age 40 years, median Expanded Disability Status Scale (EDSS) of 2, underwent two clinically indicated MRI scans (3 Tesla) within 5-14 months, and EDSS assessment after a mean of 3.0 (1.5-4.2) years. We investigated the predictive value of predefined classifications in low/high inflammatory and atrophy groups for EDSS progression (>=1.5 if baseline EDSS = 0, >=1.0 if baseline EDSS <5, >=0.5 for other) by chi-square tests and by analysis of variance (ANOVA). The classifications were based on current scientific or clinical recommendation (e.g., treatment response criteria). Brain atrophy was assessed with three different methods (SIENA, SIENAX, and FreeSurfer). Post-hoc analyses aimed to explore clinical data and dynamics of MRI outcomes as predictors in multivariate linear and logit models. RESULTS: Progression was observed in 24% of patients and was independent from treatment status. None of the predefined classifications were predictive for progression. Explorative post hoc analyses found lower baseline EDSS and higher grey matter atrophy (FreeSurfer) as best predictors (R (2) = 0.29) for EDSS progression and the accuracy was overall good (Area under the curve = 0.81). CONCLUSION: Beside EDSS at baseline, short-term grey matter atrophy is predictive for EDSS progression in treated and untreated RRMS. The development of atrophy measurements for individual risk counselling and evaluation of treatment response seems possible, but needs further validation in larger cohorts. MRI-atrophy estimates from the FreeSurfer toolbox seem to be more reliable than older methods. PMID- 27688967 TI - Evolutionary morphology of the rabbit skull. AB - The skull of leporids (rabbits and hares) is highly transformed, typified by pronounced arching of the dorsal skull and ventral flexion of the facial region (i.e., facial tilt). Previous studies show that locomotor behavior influences aspects of cranial shape in leporids, and here we use an extensive 3D geometric morphometrics dataset to further explore what influences leporid cranial diversity. Facial tilt angle, a trait that strongly correlates with locomotor mode, significantly predicts the cranial shape variation captured by the primary axis of cranial shape space, and describes a small proportion (13.2%) of overall cranial shape variation in the clade. However, locomotor mode does not correlate with overall cranial shape variation in the clade, because there are two district morphologies of generalist species, and saltators and cursorial species have similar morphologies. Cranial shape changes due to phyletic size change (evolutionary allometry) also describes a small proportion (12.5%) of cranial shape variation in the clade, but this is largely driven by the smallest living leporid, the pygmy rabbit (Brachylagus idahoensis). By integrating phylogenetic history with our geometric morphometric data, we show that the leporid cranium exhibits weak phylogenetic signal and substantial homoplasy. Though these results make it difficult to reconstruct what the 'ancestral' leporid skull looked like, the fossil records suggest that dorsal arching and facial tilt could have occurred before the origin of the crown group. Lastly, our study highlights the diversity of cranial variation in crown leporids, and highlights a need for additional phylogenetic work that includes stem (fossil) leporids and includes morphological data that captures the transformed morphology of rabbits and hares. PMID- 27688969 TI - Development and characterization of fourteen novel microsatellite markers for the chestnut short-tailed fruit bat (Carollia castanea), and cross-amplification to related species. AB - Rapid anthropogenic land use change threatens the primary habitat of the Chestnut short-tailed bat (Carollia castanea) throughout much of its range. Information on population genetic structure can inform management strategies for this widespread frugivorous bat, and effective protection of C. castanea will also benefit the more than 20 mutualistic plant species of which this bat is the primary seed disperser. To facilitate understanding of population genetic structure in this species, fourteen novel microsatellite markers were developed using restriction site-associated DNA libraries and Illumina sequencing and tested on 28 individuals from 13 locations in Costa Rica. These are the first microsatellite markers developed for C. castanea. All loci were polymorphic, with number of alleles ranging from 2-11 and average observed heterozygosity of 0.631. Markers were also cross-amplified in three additional frugivorous bat species threatened by habitat loss and fragmentation: Sowell's short-tailed bat (Carollia sowelli), Seba's short-tailed bat (Carollia perspicillata), and the Jamaican fruit bat (Artibeus jamaicensis), and 10, 11, and 8 were polymorphic, respectively. PMID- 27688970 TI - Blue hypertext is a good design decision: no perceptual disadvantage in reading and successful highlighting of relevant information. AB - BACKGROUND: Highlighted text in the Internet (i.e., hypertext) is predominantly blue and underlined. The perceptibility of these hypertext characteristics was heavily questioned by applied research and empirical tests resulted in inconclusive results. The ability to recognize blue text in foveal and parafoveal vision was identified as potentially constrained by the low number of foveally centered blue light sensitive retinal cells. The present study investigates if foveal and parafoveal perceptibility of blue hypertext is reduced in comparison to normal black text during reading. METHODS: A silent-sentence reading study with simultaneous eye movement recordings and the invisible boundary paradigm, which allows the investigation of foveal and parafoveal perceptibility, separately, was realized (comparing fixation times after degraded vs. un-degraded parafoveal previews). Target words in sentences were presented in either black or blue and either underlined or normal. RESULTS: No effect of color and underlining, but a preview benefit could be detected for first pass reading measures. Fixation time measures that included re-reading, e.g., total viewing times, showed, in addition to a preview effect, a reduced fixation time for not highlighted (black not underlined) in contrast to highlighted target words (either blue or underlined or both). DISCUSSION: The present pattern reflects no detectable perceptual disadvantage of hyperlink stimuli but increased attraction of attention resources, after first pass reading, through highlighting. Blue or underlined text allows readers to easily perceive hypertext and at the same time readers re-visited highlighted words longer. On the basis of the present evidence, blue hypertext can be safely recommended to web designers for future use. PMID- 27688968 TI - Hyperbrain features of team mental models within a juggling paradigm: a proof of concept. AB - BACKGROUND: Research on cooperative behavior and the social brain exists, but little research has focused on real-time motor cooperative behavior and its neural correlates. In this proof of concept study, we explored the conceptual notion of shared and complementary mental models through EEG mapping of two brains performing a real-world interactive motor task of increasing difficulty. We used the recently introduced participative "juggling paradigm," and collected neuro-physiological and psycho-social data. We were interested in analyzing the between-brains coupling during a dyadic juggling task, and in exploring the relationship between the motor task execution, the jugglers'skill level and the task difficulty. We also investigated how this relationship could be mirrored in the coupled functional organization of the interacting brains. METHODS: To capture the neural schemas underlying the notion of shared and complementary mental models, we examined the functional connectivity patterns and hyperbrain features of a juggling dyad involved in cooperative motor tasks of increasing difficulty. Jugglers' cortical activity was measured using two synchronized 32 channel EEG systems during dyadic juggling performed with 3, 4, 5 and 6 balls. Individual and hyperbrain functional connections were quantified through coherence maps calculated across all electrode pairs in the theta and alpha bands (4-8 and 8-12 Hz). Graph metrics were used to typify the global topology and efficiency of the functional networks for the four difficulty levels in the theta and alpha bands. RESULTS: Results indicated that, as task difficulty increased, the cortical functional organization of the more skilled juggler became progressively more segregated in both frequency bands, with a small-world organization in the theta band during easier tasks, indicative of a flow-like state in line with the neural efficiency hypothesis. Conversely, more integrated functional patterns were observed for the less skilled juggler in both frequency bands, possibly related to cognitive overload due to the difficulty of the task at hand (reinvestment hypothesis). At the hyperbrain level, a segregated functional organization involving areas of the visuo-attentional networks of both jugglers was observed in both frequency bands and for the easier task only. DISCUSSION: These results suggest that cooperative juggling is supported by integrated activity of specialized cortical areas from both brains only during easier tasks, whereas it relies on individual skills, mirrored in uncorrelated individual brain activations, during more difficult tasks. These findings suggest that task difficulty and jugglers' personal skills may influence the features of the hyperbrain network in its shared/integrative and complementary/segregative tendencies. PMID- 27688971 TI - Harvesting and chewing as constraints to forage consumption by the African savanna elephant (Loxodonta africana). AB - As a foundation for understanding the diet of African savanna elephants (Loxodonta africana), adult bulls and cows were observed over an annual cycle to determine whether harvesting (Pt ), chewing (Ct ) and handling times (Ht ) differed across food types and harvesting methods (handling time is defined as the time to harvest, chew and swallow a trunkload of food). Bulls and cows were observed 105 and 26 times, respectively (94 and 26 individuals), with a total of 64 h of feeding recorded across 32 vegetation types. Some food types took longer to harvest and chew than others, which may influence intake rate and affect choice of diet. The method used to gather a trunkload of food had a significant effect on harvesting time, with simple foraging actions being comparatively rapid and more difficult tasks taking longer. Handling time was constrained by chewing for bulls, except for the processing of roots from woody plants, which was limited by harvesting. Time to gather a trunkload had a greater influence on handling time for cows compared to bulls. Harvesting and handling times were longer for bulls than cows, with the sexes adopting foraging behaviors that best suited their energy requirements. PMID- 27688972 TI - Overland movement in African clawed frogs (Xenopus laevis): a systematic review. AB - African clawed frogs (Xenopus laevis) are often referred to as 'purely aquatic' but there are many publications which suggest extensive overland movements. Previous reviews which considered the topic have not answered the following questions: (1) is there evidence for overland dispersal in native and invasive ranges; (2) what is the range of distances moved overland; (3) when does overland movement occur; and (4) is there evidence of breeding migratory behaviour? A systematic review was chosen to synthesise and critically analyse all literature on the overland movement in Xenopus laevis. Database searches resulted in 57 documents which revealed a paucity of empirical studies, with 28 containing no data, and 19 having anecdotal content. Overwhelming evidence shows that both native and invasive populations of X. laevis move overland, with well documented examples for several other members of the genus (X. borealis, X. gilli, X. muelleri, X. fraseriand X. tropicalis). Reports of distances moved overland were from 40 m to 2 km, with no apparent difference between native and invasive ranges. Overland movements are not confined to wet seasons or conditions, but the literature suggests that moving overland does not occur in the middle of the day. Migrations to temporary water-bodies for breeding have been suggested, but without any corroborating data. PMID- 27688973 TI - New beaked whales from the late Miocene of Peru and evidence for convergent evolution in stem and crown Ziphiidae (Cetacea, Odontoceti). AB - The Ziphiidae (beaked whales) represent a large group of open-ocean odontocetes (toothed cetaceans), whose elusive and deep diving behavior prevents direct observation in their natural habitat. Despite their generally large body size, broad geographical distribution, and high species number, ziphiids thus remain poorly known. Furthermore, the evolutionary processes that have led to their extreme adaptations and impressive extant diversity are still poorly understood. Here we report new fossil beaked whales from the late Miocene of the Pisco Formation (southern Peru). The best preserved remains here described are referred to two new genera and species, the Messinian Chavinziphius maxillocristatus and the Tortonian Chimuziphius coloradensis, based on skull remains from two marine vertebrate-rich localities: Cerro Los Quesos and Cerro Colorado, respectively. C. maxillocristatus is medium sized retains a complete set of functional lower teeth, and bears robust rostral maxillary crests similar to those of the extant Berardius. By contrast, C. coloradensis is small and characterized by large triangular nasals and moderately thickened premaxillae that dorsally close the mesorostral groove. Both species confirm the high past diversity of Ziphiidae, the richest cetacean family in terms of the number of genera and species. Our new phylogenetic and biogeographical analyses depart markedly from earlier studies in dividing beaked whales into two major clades: the Messapicetus clade, which, along with other stem ziphiids, once dominated the southeastern Pacific and North Atlantic; and crown Ziphiidae, the majority of which are found in deep-water regions of the Southern Ocean, with possible subsequent dispersal both globally (Mesoplodon and Ziphius) and to the cooler waters of the northern oceans (Berardius and Hyperoodon). Despite this relatively clear separation, both lineages seem to follow similar evolutionary trends, including (1) a progressive reduction of dentition; (2) an increase in the compactness and thickness of the rostral bones; (3) similar changes in facial morphology (e.g., elevation of the vertex); and (4) an increase of body size. We suggest that these trends may be linked to a convergent ecological shift to deep diving and suction feeding. PMID- 27688974 TI - Evaluation of the effectiveness of insecticide trunk injections for control of Latoia lepida (Cramer) in the sweet olive tree Osmanthus fragrans. AB - The screening of suitable insecticides is a key factor in successfully applying trunk injection technology to ornamental plants. In this study, six chemical pesticides were selected and injected into the trunks of Osmanthus fragrans to control the nettle caterpillar, Latoia lepida (Lepidoptera: Limacodidae), using a no-pressure injection system. The absorption rate of the insecticides, the leaf loss due to insect damage, and the mortality and frass amount of L. lepida larvae were evaluated after 77 and 429 days. The results showed that 4% imidacloprid + carbosulfan and 21% abamectin + imidacloprid + omethoate had the fastest conductivity and were completely absorbed into the trunkswithin14 days; however, the efficiencies of these insecticides in controlling L. lepidawere extremely low. Additionally, the treatment 10% emamectin benzoate + clothianidin and 2.5% emamectin benzoate was almost completely absorbed within 30 days and exhibited a longer duration of insecticide efficiency (>80% mortality) in the upper and lower leaves of the canopy. Treatment with these insecticides also resulted in significantly lower leaf loss and frass amounts. We conclude that emamectin benzoate and emamectin benzoate + clothianidin have a rapid uptake into O. fragrans, and are effective as insecticides over long durations. Hence, they may be a suitable control option for L. lepida in O. fragrans plants. PMID- 27688975 TI - A genetic programming approach to oral cancer prognosis. AB - BACKGROUND: The potential of genetic programming (GP) on various fields has been attained in recent years. In bio-medical field, many researches in GP are focused on the recognition of cancerous cells and also on gene expression profiling data. In this research, the aim is to study the performance of GP on the survival prediction of a small sample size of oral cancer prognosis dataset, which is the first study in the field of oral cancer prognosis. METHOD: GP is applied on an oral cancer dataset that contains 31 cases collected from the Malaysia Oral Cancer Database and Tissue Bank System (MOCDTBS). The feature subsets that is automatically selected through GP were noted and the influences of this subset on the results of GP were recorded. In addition, a comparison between the GP performance and that of the Support Vector Machine (SVM) and logistic regression (LR) are also done in order to verify the predictive capabilities of the GP. RESULT: The result shows that GP performed the best (average accuracy of 83.87% and average AUROC of 0.8341) when the features selected are smoking, drinking, chewing, histological differentiation of SCC, and oncogene p63. In addition, based on the comparison results, we found that the GP outperformed the SVM and LR in oral cancer prognosis. DISCUSSION: Some of the features in the dataset are found to be statistically co-related. This is because the accuracy of the GP prediction drops when one of the feature in the best feature subset is excluded. Thus, GP provides an automatic feature selection function, which chooses features that are highly correlated to the prognosis of oral cancer. This makes GP an ideal prediction model for cancer clinical and genomic data that can be used to aid physicians in their decision making stage of diagnosis or prognosis. PMID- 27688976 TI - Aggressive nutrition in extremely low birth weight infants: impact on parenteral nutrition associated cholestasis and growth. AB - BACKGROUND: Parenteral nutrition associated cholestasis (PNAC) is a frequently observed pathology in extremely low birth weight (ELBW) infants. Its pathogenesis is determined by the composition and duration of parenteral nutrition (PN) as well as the tolerance of enteral feeds (EF). "Aggressive" nutrition is increasingly used in ELBW infants to improve postnatal growth. Little is known about the effect of "aggressive" nutrition on the incidence of PNAC. We analyzed the influence of implementing an "aggressive" nutritional regimen on the incidence of PNAC and growth in a cohort of ELBW infants. METHODS: ELBW infants were nourished using a "conservative" (2005-6; n = 77) or "aggressive" (2007-9; n = 85) nutritional regimen that differed in the composition of PN after birth as well as the composition and timing of advancement of EFs. We analyzed the incidence of PNAC (conjugated bilirubin > 1.5 mg/dl (25 umol/l)) corrected for confounders of cholestasis (i.e., NEC and/or gastrointestinal surgery, sepsis, birth weight, Z-score of birth weight, time on PN and male sex), growth until discharge (as the most important secondary outcome) and neonatal morbidities. RESULTS: The incidence of PNAC was significantly lower during the period of "aggressive" vs. "conservative "nutrition (27% vs. 46%, P < 0.05; adjusted OR 0.275 [0.116-0.651], P < 0.01). Body weight (+411g), head circumference (+1 cm) and length (+1 cm) at discharge were significantly higher. Extra-uterine growth failure (defined as a Z-score difference from birth to discharge lower than -1) was significantly reduced for body weight (85% vs. 35%), head circumference (77% vs. 45%) and length (85% vs. 65%) (P < 0.05). The body mass index (BMI) at discharge was significantly higher (11.1 vs. 12.4) using "aggressive" nutrition and growth became more proportionate with significantly less infants being discharged below the 10th BMI percentile (44% vs. 9%), while the percentage of infants discharged over the 90th BMI percentile (3% vs. 5%) did not significantly increase. DISCUSSION: "Aggressive" nutrition of ELBW infants was associated with a significant decrease of PNAC and marked improvement of postnatal growth.

AB - BACKGROUND: Meningitis is a major cause of mortality in tuberculosis (TB). It is not clear what factors promote central nervous system invasion and pathology but it has been reported that certain strains of Mycobacterium tuberculosis (Mtb) might have genetic traits associated with neurotropism. METHODS: In this study, we generated whole genome sequences of eight clinical strains of Mtb that were isolated from the cerebrospinal fluid (CSF) of patients presenting with tuberculous meningitis (TBM) in Malaysia, and compared them to the genomes of H37Rv and other respiratory Mtb genomes either downloaded from public databases or extracted from local sputum isolates. We aimed to find genomic features that might be distinctly different between CSF-derived and respiratory Mtb. RESULTS: Genome-wide comparisons revealed rearrangements (translocations, inversions, insertions and deletions) and non-synonymous SNPs in our CSF-derived strains that were not observed in the respiratory Mtb genomes used for comparison. These rearranged segments were rich in genes for PE (proline-glutamate)/PPE (proline proline-glutamate), transcriptional and membrane proteins. Similarly, most of the ns SNPs common in CSF strains were noted in genes encoding PE/PPE proteins. Protein globularity differences were observed among mycobacteria from CSF and respiratory sources and in proteins previously reported to be associated with TB meningitis. Transcription factors and other transcription regulators featured prominently in these proteins. Homologs of proteins associated with Streptococcus pneumoniae meningitis and Neisseria meningitidis virulence were identified in neuropathogenic as well as respiratory mycobacterial spp. examined in this study. DISCUSSION: The occurrence of in silico genetic differences in CSF-derived but not respiratory Mtb suggests their possible involvement in the pathogenesis of TBM. However, overall findings in this comparative analysis support the postulation that TB meningeal infection is more likely to be related to the expression of multiple virulence factors on interaction with host defences than to CNS tropism associated with specific genetic traits. PMID- 27688978 TI - Validation of picogram- and femtogram-input DNA libraries for microscale metagenomics. AB - High-throughput sequencing libraries are typically limited by the requirement for nanograms to micrograms of input DNA. This bottleneck impedes the microscale analysis of ecosystems and the exploration of low biomass samples. Current methods for amplifying environmental DNA to bypass this bottleneck introduce considerable bias into metagenomic profiles. Here we describe and validate a simple modification of the Illumina Nextera XT DNA library preparation kit which allows creation of shotgun libraries from sub-nanogram amounts of input DNA. Community composition was reproducible down to 100 fg of input DNA based on analysis of a mock community comprising 54 phylogenetically diverse Bacteria and Archaea. The main technical issues with the low input libraries were a greater potential for contamination, limited DNA complexity which has a direct effect on assembly and binning, and an associated higher percentage of read duplicates. We recommend a lower limit of 1 pg (~100-1,000 microbial cells) to ensure community composition fidelity, and the inclusion of negative controls to identify reagent specific contaminants. Applying the approach to marine surface water, pronounced differences were observed between bacterial community profiles of microliter volume samples, which we attribute to biological variation. This result is consistent with expected microscale patchiness in marine communities. We thus envision that our benchmarked, slightly modified low input DNA protocol will be beneficial for microscale and low biomass metagenomics.

AB - INTRODUCTION: Rituximab (RTX) is a B cell-depleting agent approved for the treatment of granulomatosis with polyangiitis (GPA). RTX reduces antibody producing precursor plasma cells and inhibits B and T cells interaction. Infections related to T cell immunodeficiency are not infrequent during RTX treatment. Our study investigated CD4 cell count and CD4/CD8 ratio in GPA patients during the first two years of long-term RTX treatment. METHODS: A single centre cohort study of 35 patients who received median total cumulative dose of cyclophosphamide (CYC) of 15 g and were treated with RTX 2 g followed by retreatment with either 2 g once annually or 1 g biannually. Serum levels of total immunoglobulin (Ig) and lymphocytes subsets were recorded at RTX initiation and at 3, 6, 12, 18 and 24 months. Low CD4 count and inverted CD4/CD8 ratio were defined as CD4 < 0.3 * 10(9)/l and ratio < 1. RESULTS: The CD4 cell count and CD4/CD8 ratio decreased slightly following the initial RTX treatment and then increased gradually during maintenance treatment. While the proportion of patients with low CD4 cell count decreased from 43% at baseline to 18% at 24 months, the ratio remained inverted in 40%. Oral daily prednisolone dose at baseline, CYC exposure and the maintenance regimen did not influence the CD4 cell count and ratio. Being older (p = 0.012) and having a higher CRP (p = 0.044) and ESR (p = 0.024) at baseline significantly increased the risk of inverted CD4/CD8 ratio at 24 months. Inverted ratio at baseline associated with lower total Ig levels during the study. CONCLUSIONS: Overall, the CD4 and CD4/CD8 ratio increased during maintenance RTX therapy in GPA with no discernible impact of other immunosuppressive therapy. However the increase in CD4 was not followed by an increase in the CD4/CD8 ratio, especially in older patients. Inverted CD4/CD8 ratio associated with lower Ig levels, suggesting a more profound B cell depleting effect of RTX with a relative increase in CD8+ lymphocytes. PMID- 27688980 TI - Spermatozoon ultrastructure in two monorchiid digeneans. AB - Spermatological characteristics of species from two monorchiid genera, Opisthomonorchis and Paramonorcheides, have been investigated, for the first time, by means of transmission electron microscopy. The ultrastructural study reveals that the mature spermatozoon of Opisthomonorchis dinema and Paramonorcheides selaris share several characters such as the presence of two axonemes of different lengths showing the 9+"1" pattern of the Trepaxonemata, a nucleus, two mitochondria, two bundles of parallel cortical microtubules, external ornamentation of the plasma membrane, spine-like bodies, granules of glycogen and similar morphologies of the anterior and posterior extremities. The slight differences between the male gamete of O. dinema and P. selaris are the length of the first axoneme and the position of the second mitochondrion. This study also elucidates the general morphology of the spermatozoon in all monorchiid species described so far, which corresponds to a unique spermatozoon type. Other interesting finds concern the spermatological similarities between monorchiid spermatozoa and the mature spermatozoon reported in the apocreadiid Neoapocreadium chabaudi. These similarities allow us to suggest a close phylogenetical relationship between the Monorchiidae and the Apocreadiidae, although more studies are needed, especially in the unexplored taxa. PMID- 27688982 TI - Self-rated mental health and race/ethnicity in the United States: support for the epidemiological paradox. AB - This paper evaluates racial/ethnic differences in self-rated mental health for adults in the United States, while controlling for demographic and socioeconomic characteristics as well as length of stay in the country. Using data from the 2010 National Health Interview Survey Cancer Control Supplement (NHIS-CCS), binomial logistic regression models are fit to estimate the association between race/ethnicity and poor/fair self-reported mental health among US Adults. The size of the analytical sample was 22,844 persons. Overall prevalence of poor/fair self-rated mental health was 7.72%, with lower prevalence among Hispanics (6.93%). Non-Hispanic blacks had the highest prevalence (10.38%). After controls for socioeconomic characteristics are incorporated in the models, Hispanics were found to have a lower probability of reporting poor/fair self-rated mental health in comparison to non-Hispanic whites (OR = 0.70; 95% CI [0.55-0.90]). No difference was found for other minority groups when compared to the reference group in the final model. Contrary to global self-rated health, Hispanics were found to have a lower probability of reporting poor/fair self-rated mental health in comparison to non-Hispanic whites. No difference was found for non-Hispanic blacks when they were compared to non-Hispanic whites. Self-rated mental health is therefore one case of a self-rating of health in which evidence supporting the epidemiological paradox is found among adults in the United States. PMID- 27688981 TI - A method for high precision sequencing of near full-length 16S rRNA genes on an Illumina MiSeq. AB - BACKGROUND: The bacterial 16S rRNA gene has historically been used in defining bacterial taxonomy and phylogeny. However, there are currently no high-throughput methods to sequence full-length 16S rRNA genes present in a sample with precision. RESULTS: We describe a method for sequencing near full-length 16S rRNA gene amplicons using the high throughput Illumina MiSeq platform and test it using DNA from human skin swab samples. Proof of principle of the approach is demonstrated, with the generation of 1,604 sequences greater than 1,300 nt from a single Nano MiSeq run, with accuracy estimated to be 100-fold higher than standard Illumina reads. The reads were chimera filtered using information from a single molecule dual tagging scheme that boosts the signal available for chimera detection. CONCLUSIONS: This method could be scaled up to generate many thousands of sequences per MiSeq run and could be applied to other sequencing platforms. This has great potential for populating databases with high quality, near full length 16S rRNA gene sequences from under-represented taxa and environments and facilitates analyses of microbial communities at higher resolution. PMID- 27688984 TI - Characteristics of the Contrast Enema Do Not Predict an Effective Bowel Management Regimen for Patients with Constipation or Fecal Incontinence. AB - BACKGROUND: A bowel management program using large volume enemas may be required for children with anorectal malformations (ARM), Hirschsprung's disease (HD), severe medically refractive idiopathic constipation (IC), and other conditions. A pretreatment contrast enema is often obtained. We sought to determine if the contrast enema findings could predict a final enema regimen. METHODS: A retrospective review was performed at a tertiary care children's hospital from 2011 to 2014 to identify patients treated with enemas in our bowel management program. Patient characteristics, contrast enema findings (including volume to completely fill the colon), and final enema regimen were collected. RESULTS: Eighty-three patients were identified (37 ARM, 7 HD, 34 IC, and 5 other). Age ranged from 10 months to 24 years, and weight ranged from 6.21 kg to 95.6 kg at the time bowel management was initiated. Linear regression showed contrast enema volume was of limited value in predicting effective therapeutic saline enema volume (R(2 )= 0.21). The addition of diagnosis, colon dilation, and contrast retention on plain x-ray the day after the contrast enema moderately improved the predictive ability of the contrast enema (R(2 )= 0.35). Median final effective enema volume was 22 mL/kg (range: 5 - 48 mL/kg). CONCLUSIONS: We were unable to demonstrate a correlation with contrast enema findings and the effective enema volume. However, no patient required a daily enema volume greater than 48 mL/kg to stay clean. PMID- 27688983 TI - Effects of grip force on median nerve deformation at different wrist angles. AB - The present study investigated the effects of grip on changes in the median nerve cross-sectional area (MNCSA) and median nerve diameter in the radial-ulnar direction (D1) and dorsal-palmar direction (D2) at three wrist angles. Twenty nine healthy participants (19 men [mean age, 24.2 +/- 1.6 years]; 10 women [mean age, 24.0 +/- 1.6 years]) were recruited. The median nerve was examined at the proximal carpal tunnel region in three grip conditions, namely finger relaxation, unclenched fist, and clenched fist. Ultrasound examinations were performed in the neutral wrist position (0 degrees ), at 30 degrees wrist flexion, and at 30 degrees wrist extension for both wrists. The grip condition and wrist angle showed significant main effects (p < 0.01) on the changes in the MNCSA, D1, and D2. Furthermore, significant interactions (p < 0.01) were found between the grip condition and wrist angle for the MNCSA, D1, and D2. In the neutral wrist position (0 degrees ), significant reductions in the MNCSA, D1, and D2 were observed when finger relaxation changed to unclenched fist and clenched fist conditions. Clenched fist condition caused the highest deformations in the median nerve measurements (MNCSA, approximately -25%; D1, -13%; D2, -12%). The MNCSA was significantly lower at 30 degrees wrist flexion and 30 degrees wrist extension than in the neutral wrist position (0 degrees ) at unclenched fist and clenched fist conditions. Notably, clenched fist condition at 30 degrees wrist flexion showed the highest reduction of the MNCSA (-29%). In addition, 30 degrees wrist flexion resulted in a lower D1 at clenched fist condition. In contrast, 30 degrees wrist extension resulted in a lower D2 at both unclenched fist and clenched fist conditions. Our results suggest that unclenched fist and clenched fist conditions cause reductions in the MNCSA, D1, and D2. More importantly, unclenched fist and clenched fist conditions at 30 degrees wrist flexion and 30 degrees wrist extension can lead to further deformation of the median nerve. PMID- 27688985 TI - Cardiovascular Disease Death Before Age 65 in 168 Countries Correlated Statistically with Biometrics, Socioeconomic Status, Tobacco, Gender, Exercise, Macronutrients, and Vitamin K. AB - BACKGROUND: Nutrition researchers recently recognized that deficiency of vitamin K2 (menaquinone: MK-4-MK-13) is widespread and contributes to cardiovascular disease (CVD). The deficiency of vitamin K2 or vitamin K inhibition with warfarin leads to calcium deposition in the arterial blood vessels. METHODS: Using publicly available sources, we collected food commodity availability data and derived nutrient profiles including vitamin K2 for people from 168 countries. We also collected female and male cohort data on early death from CVD (ages 15-64 years), insufficient physical activity, tobacco, biometric CVD risk markers, socioeconomic risk factors for CVD, and gender. The outcome measures included (1) univariate correlations of early death from CVD with each risk factor, (2) a multiple regression-derived formula relating early death from CVD (dependent variable) to macronutrient profile, vitamin K1 and K2 and other risk factors (independent variables), (3) for each risk factor appearing in the multiple regression formula, the portion of CVD risk attributable to that factor, and (4) similar univariate and multivariate analyses of body mass index (BMI), fasting blood sugar (FBS) (simulated from diabetes prevalence), systolic blood pressure (SBP), and cholesterol/ HDL-C ratio (simulated from serum cholesterol) (dependent variables) and dietary and other risk factors (independent variables). RESULTS: Female and male cohorts in countries that have vitamin K2 < 5ug per 2000 kcal/day per capita (n = 70) had about 2.2 times the rate of early CVD deaths as people in countries with > 24 ug/day of vitamin K2 per 2000 kcal/day (n = 72). A multiple regression-derived formula relating early death from CVD to dietary nutrients and other risk factors accounted for about 50% of the variance between cohorts in early CVD death. The attributable risks of the variables in the CVD early death formula were: too much alcohol (0.38%), too little vitamin K2 (6.95%), tobacco (6.87%), high blood pressure (9.01%), air pollution (9.15%), early childhood death (3.64%), poverty (7.66%), and male gender (6.13%). CONCLUSIONS: Worldwide dietary vitamin K2 data derived from food commodities add much understanding to the analysis of CVD risk factors and the etiology of CVD. Vitamin K2 in food products should be systematically quantified. Public health programs should be considered to increase the intake of vitamin K2-containing fermented plant foods such as sauerkraut, miso, and natto. PMID- 27688986 TI - Pulmonary Alveolar Microlithiasis "Stone Lungs": A Case of Clinico-Radiological Dissociation. AB - Pulmonary alveolar microlithiasis (PAM) is a rare infiltrative lung disease characterized by deposition of spherical calcium phosphate microliths called calcospherites within the alveoli. PAM was first described by Friedrich in 1856 and then by Harbitz in 1918. The disease pathogenesis is based on mutations in the SLC34A2 gene that encodes for the Type IIb sodium-phosphate cotransporter. The majority of the patients are diagnosed at an early age, usually between the ages of 20 and 40 years. The hallmark of this disease is a striking dissociation between the radiological findings and the mild clinical symptoms. We report a case of 35-year-old woman who presented post-motor vehicle accident with back pain and with minimal dyspnea on exertion. The final diagnosis was made after computed tomography and lung biopsy. The present case exhibits the remarkable clinico-radiological dissociation with complete calcification of the lungs on radiographic images with a relatively mild clinical presentation. PMID- 27688987 TI - Hypoplastic Internal Carotid Artery Co-Presenting with Neurofibromatosis and Intracranial Masses. AB - Neurofibromatosis type 1 (NF1) is associated with systemic vascular disease, and it can also affect intracranial vasculature in a small percentage of patients. Very rarely, NF1 may co-present with hypoplasia of the internal carotid artery (ICA). Prior reports have documented NF1 with bilateral optic gliomas and a unilateral hypoplastic internal carotid artery; however, we report a case with the aforementioned findings in addition to a right-sided lentiform mass. This case report further suggests a common congenital pathway related to neurofibromin loss of function resulting in both nerve sheath tumors and cerebrovascular anomalies. PMID- 27688988 TI - Chronic Pulmonary Histoplasmosis and its Clinical Significance: an Under-reported Systemic Fungal Disease. AB - Histoplasmosis is a systemic fungal mycosis caused by Histoplasma capsulatum. It is a dimorphic fungus which lives as a saprophyte in the environment and occasionally infects immunosuppressed people. H capsulatum is a ubiquitous fungus present throughout the globe and is more common in the temperate world. Human infection with H capsulatum occurs through respiratory route by inhalation of spores present in the air as droplet nuclei. Pulmonary histoplasmosis is difficult to diagnose, more so in the regions where tuberculosis is endemic, and many infected patients remain asymptomatic. In the case of immunosuppression, clinical symptoms of pulmonary infection may be seen along with chances of dissemination. We report a case of chronic pulmonary histoplasmosis in an immunocompetent individual. PMID- 27688989 TI - Comparison of Pain Scores in Postoperative Patients: Intravenous Morphine Patient Controlled Analgesia vs Iontophoretic Transdermal Fentanyl. AB - Postoperative management of pain has traditionally utilized intravenous (IV) morphine for pain control. An alternative approach to the invasive patient controlled analgesia (PCA) system is the administration of transdermal analgesics, such as fentanyl. In 2006 the Food and Drug Administration (FDA) approved the fentanyl hydrochloride (fentanyl HCl) iontophoretic transdermal system (ITS), which utilizes iontophoretic technology to produce a controlled electrical current that propels ionized fentanyl molecules into the systemic vasculature. Transdermal fentanyl has been shown to be equivalent or superior to IV morphine PCA in a variety of postoperative settings with patients experiencing decreased pain scores and a favorable side effect profile. PMID- 27688990 TI - Seizure Prophylaxis in Patients with Traumatic Brain Injury: A Single-Center Study. AB - The use of prophylactic anticonvulsants to prevent early post-traumatic seizures (PTSs) is recommended but inconsistently employed in patients with traumatic brain injury (TBI). The authors evaluated outcomes associated with prophylaxis administration in patients with TBI at a Level 1 trauma center. All patients admitted with TBI from October 2007 through May 2012 were included. Our primary outcome was the incidence of early PTSs. Secondary outcomes included mortality, length of hospital and intensive care unit (ICU) stays, and incidence of late seizures. Of the 2,111 patients with TBI, 557 (26.4%) received seizure prophylaxis and 1,554 (73.6%) did not. Two early PTSs occurred in the prophylaxis group (0.4%), whereas 21 occurred in the non-prophylaxis group (1.4%) (p = 0.05). The overall mortality rate was higher in patients who received prophylaxis (14.2% vs. 6.2%; p < 0.001), and the mean hospital length of stay (LOS) was longer (6.8 +/- 6.9 vs. 3.8 +/- 5 days; p < 0.001). In patients with severe and moderate TBI, the rate of prophylaxis administration was approximately half, whereas significantly fewer patients with mild TBI received prophylaxis than did not (20.2% vs 79.8%, p < 0.001). Lower Glasgow Coma Scale (GCS) score and longer hospital LOS were associated with early PTS (p = 0.008 for both comparisons), but sex and age were not. Brain hemorrhage was present in 78.3% of those patients who experienced early seizures. In our cohort, patients who received seizure prophylaxis had a lower GCS score, higher overall mortality rate, longer LOS, and more frequent ICU admissions, suggesting that patients who received prophylaxis were likely more severely injured.

PMID- 27688992 TI - Interventions for drug-using offenders with co-occurring mental health problems: a systematic review and economic appraisal. AB - BACKGROUND: Drug-using offenders with co-occurring mental health problems are common in the criminal justice system. A combination of drug use and mental health problems makes people more likely to be arrested for criminal involvement after release compared to offenders without a mental health problem. Previous research has evaluated interventions aimed broadly at those with a drug problem but rarely with drug use and mental health problems. This systematic review considers the effectiveness of interventions for drug-using offenders with co occurring mental health problems. METHODS: We searched 14 electronic bibliographic databases up to May 2014 and five Internet resources. The review included randomised controlled trials designed to reduce, eliminate, or prevent relapse of drug use and/or criminal activity. Data were reported on drug and crime outcomes, the identification of mental health problems, diagnoses and resource information using the Drummond checklist. The systematic review used standard methodological procedures as prescribed by the Cochrane collaboration. RESULTS: Eight trials with 2058 participants met the inclusion criteria. These evaluated: case management (RR, 1.05, 95 % CI 0.90 to 1.22, 235 participants), motivational interviewing and cognitive skills, (MD-7.42, 95 % CI-0.20.12 to 5.28, 162 participants) and interpersonal psychotherapy (RR 0.67, 95 % CI 0.3 to 1.5, 38 participants). None of these trials reported significant reductions in self-report drug misuse or crime. Four trials evaluating differing therapeutic community models showed reductions in re-incarceration (RR 0.28, 95 % CI 0.13 to 0.63, 139 participants) but not re-arrest (RR 1.65, 95 % CI 0.83 to 3.28, 370 participants) or self-report drug use (RR 0.73, 95 % CI 0.53 to 1.01, 370 participants). Mental health problems were identified across the eight trials and 17 different diagnoses were described. Two trials reported some resource information suggesting a cost-beneficial saving when comparing therapeutic communities to a prison alternative. CONCLUSIONS: Overall, the studies showed a high degree of variation, warranting a degree of caution in the interpretation of the magnitude of effect and direction of benefit for treatment outcomes. Specifically, tailored interventions are required to assess the effectiveness of interventions for drug-using offenders with co-occurring mental health problems.

PMID- 27688993 TI - Participation in the special supplemental nutrition program for women, infants, and children is not associated with early childhood socioemotional development: Results from a longitudinal cohort study. AB - Socioemotional development in early childhood has long-term impacts on health status and social outcomes, and racial and socioeconomic disparities in socioemotional skills emerge early in life. The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is an early childhood nutrition intervention with the potential to ameliorate these disparities. Our objective was to assess the impact of WIC on early socioemotional development in a longitudinal study. We examined the association between WIC participation and scores on the Brief Infant Toddler Social Emotional Assessment (BITSEA) in 327 predominantly African American mother-child dyads who were participants in the longitudinal Conditions Affecting Neurocognitive Development in Early Life (CANDLE) Study (Memphis, TN). To account for selection bias, we used within-child fixed effects to model the variability in each child's BITSEA scores over two measurement occasions (ages 12 and 24 months). Final models were adjusted for time-varying characteristics including child age, maternal stress, mental health, child abuse potential, marital status, and food stamp participation. In fully adjusted models, we found no statistically significant effect of WIC on change in socioemotional development (beta = 0.22 [SD = 0.39] and beta = - 0.58 [SD = 0.79] for BITSEA Competence and Problem subdomains, respectively). Using rigorous methods and a longitudinal study design, we found no significant association between WIC and socioemotional development in a high needs population. This finding suggests that early childhood interventions that more specifically target socioemotional development are necessary if we are to reduce racial disparities in socioemotional skills and prevent poor social and health outcomes across the life course. PMID- 27688995 TI - alpha-Melanocyte stimulating hormone promotes muscle glucose uptake via melanocortin 5 receptors. AB - OBJECTIVE: Central melanocortin pathways are well-established regulators of energy balance. However, scant data exist about the role of systemic melanocortin peptides. We set out to determine if peripheral alpha-melanocyte stimulating hormone (alpha-MSH) plays a role in glucose homeostasis and tested the hypothesis that the pituitary is able to sense a physiological increase in circulating glucose and responds by secreting alpha-MSH. METHODS: We established glucose stimulated alpha-MSH secretion using humans, non-human primates, and mouse models. Continuous alpha-MSH infusions were performed during glucose tolerance tests and hyperinsulinemic-euglycemic clamps to evaluate the systemic effect of alpha-MSH in glucose regulation. Complementary ex vivo and in vitro techniques were employed to delineate the direct action of alpha-MSH via the melanocortin 5 receptor (MC5R)-PKA axis in skeletal muscles. Combined treatment of non selective/selective phosphodiesterase inhibitor and alpha-MSH was adopted to restore glucose tolerance in obese mice. RESULTS: Here we demonstrate that pituitary secretion of alpha-MSH is increased by glucose. Peripheral alpha-MSH increases temperature in skeletal muscles, acts directly on soleus and gastrocnemius muscles to significantly increase glucose uptake, and enhances whole-body glucose clearance via the activation of muscle MC5R and protein kinase A. These actions are absent in obese mice, accompanied by a blunting of alpha-MSH induced cAMP levels in skeletal muscles of obese mice. Both selective and non selective phosphodiesterase inhibition restores alpha-MSH induced skeletal muscle glucose uptake and improves glucose disposal in obese mice. CONCLUSION: These data describe a novel endocrine circuit that modulates glucose homeostasis by pituitary alpha-MSH, which increases muscle glucose uptake and thermogenesis through the activation of a MC5R-PKA-pathway, which is disrupted in obesity. PMID- 27688996 TI - Estrogens modulate ventrolateral ventromedial hypothalamic glucose-inhibited neurons. AB - OBJECTIVE: Brain regulation of glucose homeostasis is sexually dimorphic; however, the impact sex hormones have on specific neuronal populations within the ventromedial hypothalamic nucleus (VMN), a metabolically sensitive brain region, has yet to be fully characterized. Glucose-excited (GE) and -inhibited (GI) neurons are located throughout the VMN and may play a critical role in glucose and energy homeostasis. Within the ventrolateral portion of the VMN (VL-VMN), glucose sensing neurons and estrogen receptor (ER) distributions overlap. We therefore tested the hypothesis that VL-VMN glucose sensing neurons were sexually dimorphic and regulated by 17beta-estradiol (17betaE). METHODS: Electrophysiological recordings of VL-VMN glucose sensing neurons in brain slices isolated from age- and weight-matched female and male mice were performed in the presence and absence of 17betaE. RESULTS: We found a new class of VL-VMN GI neurons whose response to low glucose was transient despite continued exposure to low glucose. Heretofore, we refer to these newly identified VL-VMN GI neurons as 'adapting' or AdGI neurons. We found a sexual dimorphic response to low glucose, with male nonadapting GI neurons, but not AdGI neurons, responding more robustly to low glucose than those from females. 17betaE blunted the response of both nonadapting GI and AdGI neurons to low glucose in both males and females, which was mediated by activation of estrogen receptor beta and inhibition of AMP activated kinase. In contrast, 17betaE had no impact on GE or non-glucose sensing neurons in either sex. CONCLUSION: These data suggest sex differences and estrogenic regulation of VMN hypothalamic glucose sensing may contribute to the sexual dimorphism in glucose homeostasis. PMID- 27688997 TI - The satiating hormone amylin enhances neurogenesis in the area postrema of adult rats. AB - OBJECTIVE: Adult neurogenesis in the subgranular zone and subventricular zone is generally accepted, but its existence in other brain areas is still controversial. Circumventricular organs, such as the area postrema (AP) have recently been described as potential neurogenic niches in the adult brain. The AP is the major site of action of the satiating hormone amylin. Amylin has been shown to promote the formation of neuronal projections originating from the AP in neonatal rodents but the role of amylin in adult neurogenesis remains unknown. METHODS: To test this, we first performed an RNA-sequencing of the AP of adult rats acutely injected with either amylin (20 MUg/kg), amylin plus the amylin receptor antagonist AC187 (500 MUg/kg) or vehicle. Second, animals were subcutaneously equipped with minipumps releasing either amylin (50 MUg/kg/day) or vehicle for 3 weeks to assess cell proliferation and differentiation with the 5' bromo-2-deoxyuridine (BrdU) technique. RESULTS: Acute amylin injections affected genes involved in pathways and processes that control adult neurogenesis. Amylin consistently upregulated NeuroD1 transcript and protein in the adult AP, and this effect was blocked by the co-administration of AC187. Further, chronic amylin treatment increased the number of newly proliferated AP-cells and significantly promoted their differentiation into neurons rather than astrocytes. CONCLUSION: Our findings revealed a novel role of the satiating hormone amylin in promoting neurogenesis in the AP of adult rats. PMID- 27688998 TI - Defining a novel leptin-melanocortin-kisspeptin pathway involved in the metabolic control of puberty. AB - OBJECTIVE: Puberty is a key developmental phenomenon highly sensitive to metabolic modulation. Worrying trends of changes in the timing of puberty have been reported in humans. These might be linked to the escalating prevalence of childhood obesity and could have deleterious impacts on later (cardio-metabolic) health, but their underlying mechanisms remain unsolved. The neuropeptide alpha MSH, made by POMC neurons, plays a key role in energy homeostasis by mediating the actions of leptin and likely participates in the control of reproduction. However, its role in the metabolic regulation of puberty and interplay with kisspeptin, an essential puberty-regulating neuropeptide encoded by Kiss1, remain largely unknown. We aim here to unveil the potential contribution of central alpha-MSH signaling in the metabolic control of puberty by addressing its role in mediating the pubertal effects of leptin and its potential interaction with kisspeptin. METHODS: Using wild type and genetically modified rodent models, we implemented pharmacological studies, expression analyses, electrophysiological recordings, and virogenetic approaches involving DREADD technology to selectively inhibit Kiss1 neurons, in order to interrogate the physiological role of a putative leptin->alpha-MSH->kisspeptin pathway in the metabolic control of puberty. RESULTS: Stimulation of central alpha-MSH signaling robustly activated the reproductive axis in pubertal rats, whereas chronic inhibition of melanocortin receptors MC3/4R, delayed puberty, and prevented the permissive effect of leptin on puberty onset. Central blockade of MC3/4R or genetic elimination of kisspeptin receptors from POMC neurons did not affect kisspeptin effects. Conversely, congenital ablation of kisspeptin receptors or inducible, DREADD-mediated inhibition of arcuate nucleus (ARC) Kiss1 neurons resulted in markedly attenuated gonadotropic responses to MC3/4R activation. Furthermore, close appositions were observed between POMC fibers and ARC Kiss1 neurons while blockade of alpha-MSH signaling suppressed Kiss1 expression in the ARC of pubertal rats. CONCLUSIONS: Our physiological, virogenetic, and functional genomic studies document a novel alpha-MSH->kisspeptin->GnRH neuronal signaling pathway involved in transmitting the permissive effects of leptin on pubertal maturation, which is relevant for the metabolic (and, eventually, pharmacological) regulation of puberty onset. PMID- 27688999 TI - Mechanisms underlying prorenin actions on hypothalamic neurons implicated in cardiometabolic control. AB - BACKGROUND: Hypertension and obesity are highly interrelated diseases, being critical components of the metabolic syndrome. Despite the growing prevalence of this syndrome in the world population, efficient therapies are still missing. Thus, identification of novel targets and therapies are warranted. An enhanced activity of the hypothalamic renin-angiotensin system (RAS), including the recently discovered prorenin (PR) and its receptor (PRR), has been implicated as a common mechanism underlying aberrant sympatho-humoral activation that contributes to both metabolic and cardiovascular dysregulation in the metabolic syndrome. Still, the identification of precise neuronal targets, cellular mechanisms and signaling pathways underlying PR/PRR actions in cardiovascular- and metabolic related hypothalamic nuclei remain unknown. METHODS AND RESULTS: Using a multidisciplinary approach including patch-clamp electrophysiology, live calcium imaging and immunohistochemistry, we aimed to elucidate cellular mechanisms underlying PR/PRR actions within the hypothalamic supraoptic (SON) and paraventricular nucleus (PVN), key brain areas previously involved in cardiometabolic regulation. We show for the first time that PRR is expressed in magnocellular neurosecretory cells (MNCs), and to a lesser extent, in presympathetic PVN neurons (PVNPS). Moreover, we show that while PRR activation efficiently stimulates the firing activity of both MNCs and PVNPS neurons, these effects involved AngII-independent and AngII-dependent mechanisms, respectively. In both cases however, PR excitatory effects involved an increase in intracellular Ca(2+) levels and a Ca(2+)-dependent inhibition of a voltage-gated K(+) current. CONCLUSIONS: We identified novel neuronal targets and cellular mechanisms underlying PR/PRR actions in critical hypothalamic neurons involved in cardiometabolic regulation. This fundamental mechanistic information regarding central PR/PRR actions is essential for the development of novel RAS-based therapeutic targets for the treatment of cardiometabolic disorders in obesity and hypertension. PMID- 27689000 TI - Reprogramming the body weight set point by a reciprocal interaction of hypothalamic leptin sensitivity and Pomc gene expression reverts extreme obesity. AB - OBJECTIVE: A major challenge for obesity treatment is the maintenance of reduced body weight. Diet-induced obese mice are resistant to achieving normoweight once the obesogenic conditions are reversed, in part because lowered circulating leptin leads to a reduction in metabolic rate and a rebound of hyperphagia that defend the previously elevated body weight set point. Because hypothalamic POMC is a central leptin target, we investigated whether changes in circulating leptin modify Pomc expression to maintain normal energy balance in genetically predisposed obese mice. METHODS: Mice with reversible Pomc silencing in the arcuate nucleus (ArcPomc (-/-)) become morbidly obese eating low-fat chow. We measured body composition, food intake, plasma leptin, and leptin sensitivity in ArcPomc (-/-) mice weight-matched to littermate controls by calorie restriction, either from weaning or after developing obesity. Pomc was reactivated by tamoxifen-dependent Cre recombinase transgenes. Long acting PASylated leptin was administered to weight-reduced ArcPomc (-/-) mice to mimic the super-elevated leptin levels of obese mice. RESULTS: ArcPomc (-/-) mice had increased adiposity and leptin levels shortly after weaning. Despite chronic calorie restriction to achieve normoweight, ArcPomc (-/-) mice remained moderately hyperleptinemic and resistant to exogenous leptin's effects to reduce weight and food intake. However, subsequent Pomc reactivation in weight-matched ArcPomc (-/-) mice normalized plasma leptin, leptin sensitivity, adiposity, and food intake. In contrast, extreme hyperleptinemia induced by PASylated leptin blocked the full restoration of hypothalamic Pomc expression in calorie restricted ArcPomc (-/-) mice, which consequently regained 30% of their lost body weight and attained a metabolic steady state similar to that of tamoxifen treated obese ArcPomc (-/-) mice. CONCLUSIONS: Pomc reactivation in previously obese, calorie-restricted ArcPomc (-/-) mice normalized energy homeostasis, suggesting that their body weight set point was restored to control levels. In contrast, massively obese and hyperleptinemic ArcPomc (-/-) mice or those weight-matched and treated with PASylated leptin to maintain extreme hyperleptinemia prior to Pomc reactivation converged to an intermediate set point relative to lean control and obese ArcPomc (-/-) mice. We conclude that restoration of hypothalamic leptin sensitivity and Pomc expression is necessary for obese ArcPomc (-/-) mice to achieve and sustain normal metabolic homeostasis; whereas deficits in either parameter set a maladaptive allostatic balance that defends increased adiposity and body weight. PMID- 27689001 TI - Adiponectin potentiates the acute effects of leptin in arcuate Pomc neurons. AB - OBJECTIVE: Adiponectin receptors (AdipoRs) are located on neurons of the hypothalamus involved in metabolic regulation - including arcuate proopiomelanocortin (Pomc) and Neuropeptide Y/Agouti-related peptide (NPY/AgRP) neurons. AdipoRs play a critical role in regulating glucose and fatty acid metabolism by initiating several signaling cascades overlapping with Leptin receptors (LepRs). However, the mechanism by which adiponectin regulates cellular activity in the brain remains undefined. METHODS: In order to resolve this issue, we utilized neuron-specific transgenic mouse models to identify Pomc and NPY/AgRP neurons which express LepRs for patch-clamp electrophysiology experiments. RESULTS: We found that leptin and adiponectin synergistically activated melanocortin neurons in the arcuate nucleus. Conversely, NPY/AgRP neurons were inhibited in response to adiponectin. The adiponectin-induced depolarization of arcuate Pomc neurons occurred via activation of Phosphoinositide-3-kinase (PI3K) signaling, independent of 5' AMP-activated protein kinase (AMPK) activity. Adiponectin also activated melanocortin neurons at various physiological glucose levels. CONCLUSIONS: Our results demonstrate a requirement for PI3K signaling in the acute adiponectin-induced effects on the cellular activity of arcuate melanocortin neurons. Moreover, these data provide evidence for PI3K as a substrate for both leptin and adiponectin to regulate energy balance and glucose metabolism via melanocortin activity. PMID- 27689002 TI - Physiological role for leptin in the control of thermal conductance. AB - OBJECTIVE: To investigate the role played by leptin in thermoregulation, we studied the effects of physiological leptin replacement in leptin-deficient ob/ob mice on determinants of energy balance, thermogenesis and heat retention under 3 different ambient temperatures. METHODS: The effects of housing at 14 degrees C, 22 degrees C or 30 degrees C on core temperature (telemetry), energy expenditure (respirometry), thermal conductance, body composition, energy intake, and locomotor activity (beam breaks) were measured in ob/ob mice implanted subcutaneously with osmotic minipumps at a dose designed to deliver a physiological replacement dose of leptin or its vehicle-control. RESULTS: As expected, the hypothermic phenotype of ob/ob mice was partially rescued by administration of leptin at a dose that restores plasma levels into the physiological range. This effect of leptin was not due to increased energy expenditure, as cold exposure markedly and equivalently stimulated energy expenditure and induced activation of brown adipose tissue irrespective of leptin treatment. Instead, the effect of physiological leptin replacement to raise core body temperature of cold-exposed ob/ob mice was associated with reduced thermal conductance, implying a physiological role for leptin in heat conservation. Finally, both leptin- and vehicle-treated ob/ob mice failed to match energy intake to expenditure during cold exposure, resulting in weight loss. CONCLUSIONS: The physiological effect of leptin to reduce thermal conductance contributes to maintenance of core body temperature under sub-thermoneutral conditions. PMID- 27689004 TI - Impact of statistical models on the prediction of type 2 diabetes using non targeted metabolomics profiling. AB - OBJECTIVE: Characterizing specific metabolites in sub-clinical phases preceding the onset of type 2 diabetes to enable efficient preventive and personalized interventions. RESEARCH DESIGN AND METHODS: We developed predictive models of type 2 diabetes using two strategies. One strategy focused on the probability of incidence only and was based on logistic regression (MRS1); the other strategy accounted for the age at diagnosis of diabetes and was based on Cox regression (MRS2). We assessed 293 metabolites using non-targeted metabolomics in fasting plasma samples of 1,044 participants (including 231 incident cases over 9 years) used as training population; and fasting serum samples of 128 participants (64 incident cases versus 64 controls) used as validation population. We applied a LASSO-based variable selection aiming at maximizing the out-of-sample area under the receiver operating characteristic curve (AROC) and integrated AROC. RESULTS: Sixteen and 17 metabolites were selected for MRS1 and MRS2, respectively, with AROC = 90% and 73% in the training and validation populations, respectively for MRS1. MRS2 had a similar performance and was significantly associated with a younger age of onset of type 2 diabetes (beta = -3.44 years per MRS2 SD in the training population, p = 1.56 * 10(-7); beta = -4.73 years per MRS2 SD in the validation population, p = 4.04 * 10(-3)). CONCLUSIONS: Overall, this study illustrates that metabolomics improves prediction of type 2 diabetes incidence of 4.5% on top of known clinical and biological markers, reaching 90% in total AROC, which is considered the threshold for clinical validity, suggesting it may be used in targeting interventions to prevent type 2 diabetes. PMID- 27689003 TI - TNP [N2-(m-Trifluorobenzyl), N6-(p-nitrobenzyl)purine] ameliorates diet induced obesity and insulin resistance via inhibition of the IP6K1 pathway. AB - OBJECTIVE: Obesity and type 2 diabetes (T2D) lead to various life-threatening diseases such as coronary heart disease, stroke, osteoarthritis, asthma, and neurodegeneration. Therefore, extensive research is ongoing to identify novel pathways that can be targeted in obesity/T2D. Deletion of the inositol pyrophosphate (5-IP7) biosynthetic enzyme, inositol hexakisphosphate kinase-1 (IP6K1), protects mice from high fat diet (HFD) induced obesity (DIO) and insulin resistance. Yet, whether this pathway is a valid pharmacologic target in obesity/T2D is not known. Here, we demonstrate that TNP [N2-(m-Trifluorobenzyl), N6-(p-nitrobenzyl)purine], a pan-IP6K inhibitor, has strong anti-obesity and anti diabetic effects in DIO mice. METHODS: Q-NMR, GTT, ITT, food intake, energy expenditure, QRT-PCR, ELISA, histology, and immunoblot studies were conducted in short (2.5-week)- and long (10-week)-term TNP treated DIO C57/BL6 WT and IP6K1-KO mice, under various diet and temperature conditions. RESULTS: TNP, when injected at the onset of HFD-feeding, decelerates initiation of DIO and insulin resistance. Moreover, TNP facilitates weight loss and restores metabolic parameters, when given to DIO mice. However, TNP does not reduce weight gain in HFD-fed IP6K1-KO mice. TNP specifically enhances insulin sensitivity in DIO mice via Akt activation. TNP decelerates weight gain primarily by enhancing thermogenic energy expenditure in the adipose tissue. Accordingly, TNP's effect on body weight is partly abolished whereas its impact on glucose homeostasis is preserved at thermoneutral temperature. CONCLUSION: Pharmacologic inhibition of the inositol pyrophosphate pathway has strong therapeutic potential in obesity, T2D, and other metabolic diseases. PMID- 27689006 TI - Depot specific differences in the adipogenic potential of precursors are mediated by collagenous extracellular matrix and Flotillin 2 dependent signaling. AB - OBJECTIVE: Adipose tissue shows a high degree of plasticity, and adipocyte hyperplasia is an important mechanism for adipose tissue expansion. Different adipose depots respond differently to an increased demand for lipid storage. Orchestrating cellular expansion in vivo requires extracellular matrix (ECM) remodeling and a high degree of interaction between cells and ECM. METHODS: We studied decellularized primary adipose stromal cell derived ECM of different adipose depots and reseeded them with primary adipose precursors. We tested ECM effect on adipocyte differentiation and analyzed ECM composition using proteomic and immunohistochemical approaches to identify factors in the ECM influencing adipogenesis. RESULTS: We show that the ECM of an adipose depot is the major determinant for the differentiation capacity of primary preadipocytes. Visceral adipose tissue stromal cells differentiate less than subcutaneous cells, which, in turn, are less adipogenic than BAT-derived cells. This effect is based on the ECM composition of the respective depot and not dependent on the precursor origin. Addition of vitamin C pronounces the pro-adipogenic effects of the ECM, indicating the importance of collagenous ECM in mediating the effect. Using a proteomic global and a targeted downstream analysis, we identify Flotillin 2 as a protein enriched in pro-adipogenic ECM, which is involved in orchestrating ECM to preadipocyte signaling. CONCLUSIONS: We show that adipose tissue SVF secretes collagenous ECM, which directly modulates terminal differentiation of adipocyte precursors in a depot specific manner. These data demonstrate the importance of the tissue microenvironment in preadipocyte differentiation. PMID- 27689005 TI - Defects in muscle branched-chain amino acid oxidation contribute to impaired lipid metabolism. AB - OBJECTIVE: Plasma levels of branched-chain amino acids (BCAA) are consistently elevated in obesity and type 2 diabetes (T2D) and can also prospectively predict T2D. However, the role of BCAA in the pathogenesis of insulin resistance and T2D remains unclear. METHODS: To identify pathways related to insulin resistance, we performed comprehensive gene expression and metabolomics analyses in skeletal muscle from 41 humans with normal glucose tolerance and 11 with T2D across a range of insulin sensitivity (SI, 0.49 to 14.28). We studied both cultured cells and mice heterozygous for the BCAA enzyme methylmalonyl-CoA mutase (Mut) and assessed the effects of altered BCAA flux on lipid and glucose homeostasis. RESULTS: Our data demonstrate perturbed BCAA metabolism and fatty acid oxidation in muscle from insulin resistant humans. Experimental alterations in BCAA flux in cultured cells similarly modulate fatty acid oxidation. Mut heterozygosity in mice alters muscle lipid metabolism in vivo, resulting in increased muscle triglyceride accumulation, increased plasma glucose, hyperinsulinemia, and increased body weight after high-fat feeding. CONCLUSIONS: Our data indicate that impaired muscle BCAA catabolism may contribute to the development of insulin resistance by perturbing both amino acid and fatty acid metabolism and suggest that targeting BCAA metabolism may hold promise for prevention or treatment of T2D. PMID- 27689007 TI - Genetic backgrounds determine brown remodeling of white fat in rodents. AB - OBJECTIVE: Genetic background largely contributes to the complexity of metabolic responses and dysfunctions. Induction of brown adipose features in white fat, known as brown remodeling, has been appreciated as a promising strategy to offset the positive energy balance in obesity and further to improve metabolism. Here we address the effects of genetic background on this process. METHODS: We investigated browning remodeling in a depot-specific manner by comparing the response of C57BL/6J, 129/Sv and FVB/NJ mouse strains to cold. RESULTS: Surprisingly, 129/Sv and FVB/NJ mice showed distinct brown remodeling features despite their similar resistance to metabolic disorders in comparison to the obesity-prone C57BL/6J mice. FVB/NJ mice demonstrated a preference of brown remodeling in inguinal subcutaneous white adipose tissue (iWAT), whereas 129/Sv mice displayed robust brown remodeling in visceral epididymal fat (eWAT). We further compared gene expression in different depots by RNA-sequencing and identified Hoxc10 as a novel "brake" of brown remodeling in iWAT. CONCLUSION: Rodent genetic background determines the brown remodeling of different white fat depots. This study provides new insights into the role of genetic variation in fat remodeling in susceptibility to metabolic diseases. PMID- 27689008 TI - Adipose tissue (P)RR regulates insulin sensitivity, fat mass and body weight. AB - OBJECTIVE: We previously demonstrated that the handle-region peptide, a prorenin/renin receptor [(P)RR] blocker, reduces body weight and fat mass and may improve insulin sensitivity in high-fat fed mice. We hypothesized that knocking out the adipose tissue (P)RR gene would prevent weight gain and insulin resistance. METHODS: An adipose tissue-specific (P)RR knockout (KO) mouse was created by Cre-loxP technology using AP2-Cre recombinase mice. Because the (P)RR gene is located on the X chromosome, hemizygous males were complete KO and had a more pronounced phenotype on a normal diet (ND) diet compared to heterozygous KO females. Therefore, we challenged the female mice with a high-fat diet (HFD) to uncover certain phenotypes. Mice were maintained on either diet for 9 weeks. RESULTS: KO mice had lower body weights compared to wild-types (WT). Only hemizygous male KO mice presented with lower total fat mass, higher total lean mass as well as smaller adipocytes compared to WT mice. Although food intake was similar between genotypes, locomotor activity during the active period was increased in both male and female KO mice. Interestingly, only male KO mice had increased O2 consumption and CO2 production during the entire 24-hour period, suggesting an increased basal metabolic rate. Although glycemia during a glucose tolerance test was similar, KO males as well as HFD-fed females had lower plasma insulin and C-peptide levels compared to WT mice, suggesting improved insulin sensitivity. Remarkably, all KO animals exhibited higher circulating adiponectin levels, suggesting that this phenotype can occur even in the absence of a significant reduction in adipose tissue weight, as observed in females and, thus, may be a specific effect related to the (P)RR. CONCLUSIONS: (P)RR may be an important therapeutic target for the treatment of obesity and its associated complications such as type 2 diabetes. PMID- 27689009 TI - Myocardin-related transcription factor A (MRTFA) regulates the fate of bone marrow mesenchymal stem cells and its absence in mice leads to osteopenia. AB - OBJECTIVE: Arising from common progenitors in the bone marrow, adipogenesis and osteogenesis are closely associated yet mutually exclusive during bone marrow mesenchymal stem cell (BMSC) development. Previous studies have shown that morphological changes can affect the early commitment of pluripotent BMSCs to the adipose versus osteoblastic lineage via modulation of RhoA activity. The RhoA pathway regulates actin polymerization to promote the incorporation of globular actin (G-actin) into filamentous actin (F-actin). In doing so, myocardin-related transcription factors (MRTFs) dissociate from bound G-actin and enter the nucleus to co-activate serum response factor (SRF) target gene expression. In this study, we investigated whether MRTFA/SRF is acting downstream of the RhoA pathway to regulate BMSC commitment in mice. METHODS: The effects of knocking out MRTFA on skeletal homeostasis was studied in MRTFA KO mice using micro-CT, QPCR and western blot assays. To determine how MRTFA affects the mechanisms regulating BMSC fate decisions, primary bone marrow stromal cells from WT and MRTFA KO mice as well as C3H10T1/2 cell lines were analyzed in vitro. RESULTS: Global MRTFA KO mice have lower whole body weight, shorter femoral and tibial lengths as well as significantly decreased bone mass in their femurs. BMSCs isolated from the KO mice show increased adipogenesis and reduced osteogenesis when compared to WT littermates. KO mice, particularly females, develop osteopenia with age, and this was enhanced by a high fat diet. Over-expression of MRTFA or SRF enhances osteogenesis in CH310T1/2 cell lines. Sca1(+), CD45(-) cells from KO marrow express lower amounts of smooth muscle actin (SMA) and TAZ/YAP target genes compared to WT counterparts. CONCLUSION: This study identified MRTFA as a novel regulator of skeletal homeostasis by regulating the balance between adipogenic and osteogenic differentiation of BMSCs. We propose that MRTFA promotes the osteogenic activity of TAZ/YAP by maintaining SMA production in BMSCs. PMID- 27689010 TI - Knockdown of ATP citrate lyase in pancreatic beta cells does not inhibit insulin secretion or glucose flux and implicates the acetoacetate pathway in insulin secretion. AB - OBJECTIVE: Glucose-stimulated insulin secretion in pancreatic beta cells requires metabolic signals including the generation of glucose-derived short chain acyl CoAs in the cytosol from mitochondrially-derived metabolites. One concept of insulin secretion is that ATP citrate lyase generates short chain acyl-CoAs in the cytosol from mitochondrially-derived citrate. Of these, malonyl-CoA, is believed to be an important signal in insulin secretion. Malonyl-CoA is also a precursor for lipids. Our recent evidence suggested that, in the mitochondria of beta cells, glucose-derived pyruvate can be metabolized to acetoacetate that is exported to the cytosol and metabolized to the same short chain acyl-CoAs and fatty acids that can be derived from citrate. We tested for redundancy of the citrate pathway. METHODS: We inhibited ATP citrate lyase activity using hydroxycitrate as well as studying a stable cell line generated with shRNA knockdown of ATP citrate lyase in the pancreatic beta cell line INS-1 832/13. RESULTS: In both instances glucose-stimulated insulin release was not inhibited. Mass spectrometry analysis showed that the flux of carbon from [U-(13)C]glucose and/or [U-(13)C]alpha-ketoisocaproic acid (KIC) into short chain acyl-CoAs in cells with hydroxycitrate-inhibited ATP citrate lyase or in the cell line with stable severe (>90%) shRNA knockdown of ATP citrate lyase was similar to the controls. Both (13)C-glucose and (13)C-KIC introduced substantial (13)C labeling into acetyl-CoA, malonyl-CoA, and HMG-CoA under both conditions. Glucose flux into fatty acids was not affected by ATP citrate lyase knockdown. CONCLUSION: The results establish the involvement of the acetoacetate pathway in insulin secretion in pancreatic beta cells. PMID- 27689012 TI - Inhibition of RORalpha/gamma suppresses atherosclerosis via inhibition of both cholesterol absorption and inflammation. AB - OBJECTIVE: Cardiovascular diseases (CVDs) are the leading cause of mortality in Western countries. Atherosclerosis is a multi-step inflammatory disease characterized at early stages by accumulation of cholesterol in the arterial wall followed by recruitment of immune cells. We sought to determine if pharmacological suppression of RORalpha/gamma activity is beneficial in treatment of atherosclerosis. METHODS: To identify the role of RORalpha and RORgamma in atherosclerosis, we used the LDL-R(-/-) mouse model of atherosclerosis placed on a high cholesterol diet treated with SR1001, a RORalpha/gamma inverse agonist, for four weeks. RESULTS: Our results demonstrate that treatment with the ROR inverse agonist substantially decreases plaque formation in vivo. The mechanism of the anti-atherogenic activity of the inhibition of RORalpha/gamma activity appeared to be due to targeting two distinct pathways. SR1001 treatment reduced plasma low density lipoprotein (LDL) level without affecting high density lipoprotein (HDL) via increasing intestinal cholesterol excretion. Treatment with SR1001 also induced an anti-atherogenic immune profile that was characterized by a reduction in Th17 cells and an increase in Treg and Th2 cells. Our data suggest that RORalpha and RORgamma play a critical role in atherosclerosis development by regulating at least two major pathways important in the pathology of this disease: cholesterol flux and inflammation. CONCLUSION: Our data suggest that pharmacological targeting of RORalpha/gamma may be an effective method for treatment of atherosclerosis offering a distinct mechanism of action relative to statins. PMID- 27689011 TI - The regulator of G-protein signaling RGS16 promotes insulin secretion and beta cell proliferation in rodent and human islets. AB - OBJECTIVE: G protein-coupled receptor (GPCR) signaling regulates insulin secretion and pancreatic beta cell-proliferation. While much knowledge has been gained regarding how GPCRs are activated in beta cells, less is known about the mechanisms controlling their deactivation. In many cell types, termination of GPCR signaling is controlled by the family of Regulators of G-protein Signaling (RGS). RGS proteins are expressed in most eukaryotic cells and ensure a timely return to the GPCR inactive state upon removal of the stimulus. The aims of this study were i) to determine if RGS16, the most highly enriched RGS protein in beta cells, regulates insulin secretion and beta-cell proliferation and, if so, ii) to elucidate the mechanisms underlying such effects. METHODS: Mouse and human islets were infected with recombinant adenoviruses expressing shRNA or cDNA sequences to knock-down or overexpress RGS16, respectively. 60 h post-infection, insulin secretion and cAMP levels were measured in static incubations in the presence of glucose and various secretagogues. beta-cell proliferation was measured in infected islets after 72 h in the presence of 16.7 mM glucose +/- somatostatin and various inhibitors. RESULTS: RGS16 mRNA levels are strongly up-regulated in islets of Langerhans under hyperglycemic conditions in vivo and ex vivo. RGS16 overexpression stimulated glucose-induced insulin secretion in isolated mouse and human islets while, conversely, insulin secretion was impaired following RGS16 knock-down. Insulin secretion was no longer affected by RGS16 knock-down when islets were pre-treated with pertussis toxin to inactivate Galphai/o proteins, or in the presence of a somatostatin receptor antagonist. RGS16 overexpression increased intracellular cAMP levels, and its effects were blocked by an adenylyl cyclase inhibitor. Finally, RGS16 overexpression prevented the inhibitory effect of somatostatin on insulin secretion and beta-cell proliferation. CONCLUSIONS: Our results identify RGS16 as a novel regulator of beta-cell function that coordinately controls insulin secretion and proliferation by limiting the tonic inhibitory signal exerted by delta-cell-derived somatostatin in islets. PMID- 27689013 TI - Roux-en-Y gastric bypass surgery is effective in fibroblast growth factor-21 deficient mice. AB - OBJECTIVE: The mechanisms by which bariatric surgeries so effectively and lastingly reduce body weight and normalize metabolic dysfunction are not well understood. Fibroblast growth fator-21 (FGF21) is a key regulator of metabolism and is currently considered for treatment of obesity. Although elevated by acute food deprivation, it is downregulated after weight loss induced by chronic calorie restriction but not after Roux-en-Y gastric bypass surgery. Therefore, the goal of the present study was to assess the role of FGF21-signaling in the beneficial effects of Roux-en-Y gastric bypass surgery (RYGB). METHODS: High-fat diet-induced obese FGF21-deficient (FGF21(-/-)) and wildtype (WT) mice were subjected to RYGB, sham surgery, or caloric restriction to match body weight of RYGB mice. Body weight, body composition, food intake, energy expenditure, glucose tolerance, and insulin sensitivity, as well as plasma levels and hepatic mRNA expression of FGF21 were measured. RESULTS: Hepatic expression and plasma levels of FGF21 are higher after RYGB compared with similar weight loss induced by caloric restriction, suggesting that elevated FGF21 might play a role in preventing increased hunger and weight regain after RYGB. However, although the body weight differential between RYGB and sham surgery was significantly reduced in FGF21(-/-) mice, RYGB induced similarly sustained body weight and fat mass loss, initial reduction of food intake, increased energy expenditure, and improvements in glycemic control in FGF21(-/-) and WT mice. CONCLUSIONS: FGF21 signaling is not a critical single factor for the beneficial metabolic effects of RYGB. This may open up the possibility to use FGF21 as adjuvant therapy in patients with ineffective bariatric surgeries. PMID- 27689015 TI - Sex differences in obesity development in pair-fed neuronal lipoprotein lipase deficient mice. AB - OBJECTIVE: Compared to men, postmenopausal women suffer from a disproportionate burden of many co-morbidities associated with obesity, e.g. cardiovascular disease, cancer, and dementia. The underlying mechanism for this sex difference is not well understood but is believed to relate to absence of the protective effect of estrogen through the action of estrogen receptor alpha (ERalpha) in the central nervous system. With the recently developed neuron-specific lipoprotein lipase deficient mice (NEXLPL-/-) (Wang et al., Cell Metabolism, 2011 [15]), we set to explore the possible role of lipid sensing in sex differences in obesity development. METHODS: Both male and female NEXLPL-/- mice and littermate WT controls were subjected to pair feeding (pf) where daily food amount given was adjusted according to body weight to match the food intake of ad libitum (ad) fed control WT mice. Food intake and body weight were measured daily, and pair feeding was maintained to 42 wk in male mice and to 38 wk in female mice. Various brain regions of the mice were harvested, and ERalpha gene expression was examined in both male and female NEXLPL-/- and WT control mice under both ad- and pf-fed conditions. RESULTS: Although both male and female NEXLPL-/- mice developed obesity similarly on standard chow, male NEXLPL-/- mice still developed obesity under with pair feeding, but on a much delayed time course, while female NEXLPL-/- mice were protected from extra body weight and fat mass gain compared to pair-fed WT control mice. Pair feeding alone induced extra fat mass gain in both male and female WT mice, and this was mostly driven by the reduction in physical activity. LPL deficiency resulted in an increase in ERalpha mRNA in the hypothalamus of ad-fed female mice, while pair feeding alone also resulted in an increase of ERalpha in both female WT control and NEXLPL-/- mice. The effect on increasing ERalpha by pair feeding and LPL deficiency was additive in pair-fed female NEXLPL-/- mice. ERalpha mRNA levels were not significantly modified in other brain regions examined, nor in the hypothalamus of male NEXLPL-/- mice compared to control mice. CONCLUSIONS: These results suggest that the mechanism underlying ERalpha regulation of body weight interacts with the LPL-dependent lipid processing in the hypothalamus in a sex specific way. ERalpha could provide the link between brain lipid sensing and sex differences in obesity development. This study has the potential important clinical implication to provide better management for women who suffer from obesity and obesity-related co-morbidities. PMID- 27689016 TI - Dynamic DNA methylation landscape defines brown and white cell specificity during adipogenesis. AB - OBJECTIVE: DNA methylation may be a stable epigenetic contributor to defining fat cell lineage. METHODS: We performed reduced representation bisulfite sequencing (RRBS) and RNA-seq to depict a genome-wide integrative view of the DNA methylome and transcriptome during brown and white adipogenesis. RESULTS: Our analysis demonstrated that DNA methylation is a stable epigenetic signature for brown and white cell lineage before, during, and after differentiation. We identified 31 genes whose promoters were significantly differentially methylated between white and brown adipogenesis at all three time points of differentiation. Among them, five genes belong to the Hox family; their expression levels were anti-correlated with promoter methylation, suggesting a regulatory role of DNA methylation in transcription. Blocking DNA methylation with 5-Aza-cytidine increased the expression of these genes, with the most prominent effect on Hoxc10, a repressor of BAT marker expression. CONCLUSIONS: Our data suggest that DNA methylation may play an important role in lineage-specific development in adipocytes. PMID- 27689014 TI - Fibroblast activation protein (FAP) as a novel metabolic target. AB - OBJECTIVE: Fibroblast activation protein (FAP) is a serine protease belonging to a S9B prolyl oligopeptidase subfamily. This enzyme has been implicated in cancer development and recently reported to regulate degradation of FGF21, a potent metabolic hormone. Using a known FAP inhibitor, talabostat (TB), we explored the impact of FAP inhibition on metabolic regulation in mice. METHODS: To address this question we evaluated the pharmacology of TB in various mouse models including those deficient in FGF21, GLP1 and GIP signaling. We also studied the ability of FAP to process FGF21 in vitro and TB to block FAP enzymatic activity. RESULTS: TB administration to diet-induced obese (DIO) animals led to profound decreases in body weight, reduced food consumption and adiposity, increased energy expenditure, improved glucose tolerance and insulin sensitivity, and lowered cholesterol levels. Total and intact plasma FGF21 were observed to be elevated in TB-treated DIO mice but not lean animals where the metabolic impact of TB was significantly attenuated. Furthermore, and in stark contrast to naive DIO mice, the administration of TB to obese FGF21 knockout animals demonstrated no appreciable effect on body weight or any other measures of metabolism. In support of these results we observed no enzymatic degradation of human FGF21 at either end of the protein when FAP was inhibited in vitro by TB. CONCLUSIONS: We conclude that pharmacological inhibition of FAP enhances levels of FGF21 in obese mice to provide robust metabolic benefits not observed in lean animals, thus validating this enzyme as a novel drug target for the treatment of obesity and diabetes. PMID- 27689017 TI - Osteocalcin is necessary and sufficient to maintain muscle mass in older mice. AB - OBJECTIVE: A decrease in muscle protein turnover and therefore in muscle mass is a hallmark of aging. Because the circulating levels of the bone-derived hormone osteocalcin decline steeply during aging in mice, monkeys and humans we asked here whether this hormone might regulate muscle mass as mice age. METHODS: We examined muscle mass and strength in mice lacking osteocalcin (Ocn-/-) or its receptor in all cells (Gprc6a-/-) or specifically in myofibers (Gprc6a Mck -/-) as well as in 9 month-old WT mice receiving exogenous osteocalcin for 28 days. We also examined protein synthesis in WT and Gprc6a-/- mouse myotubes treated with osteocalcin. RESULTS: We show that osteocalcin signaling in myofibers is necessary to maintain muscle mass in older mice in part because it promotes protein synthesis in myotubes without affecting protein breakdown. We further show that treatment with exogenous osteocalcin for 28 days is sufficient to increase muscle mass of 9-month-old WT mice. CONCLUSION: This study uncovers that osteocalcin is necessary and sufficient to prevent age-related muscle loss in mice. PMID- 27689018 TI - The diabetes medication Canagliflozin reduces cancer cell proliferation by inhibiting mitochondrial complex-I supported respiration. AB - OBJECTIVE: The sodium-glucose transporter 2 (SGLT2) inhibitors Canagliflozin and Dapagliflozin are recently approved medications for type 2 diabetes. Recent studies indicate that SGLT2 inhibitors may inhibit the growth of some cancer cells but the mechanism(s) remain unclear. METHODS: Cellular proliferation and clonogenic survival were used to assess the sensitivity of prostate and lung cancer cell growth to the SGLT2 inhibitors. Oxygen consumption, extracellular acidification rate, cellular ATP, glucose uptake, lipogenesis, and phosphorylation of AMP-activated protein kinase (AMPK), acetyl-CoA carboxylase, and the p70S6 kinase were assessed. Overexpression of a protein that maintains complex-I supported mitochondrial respiration (NDI1) was used to establish the importance of this pathway for mediating the anti-proliferative effects of Canagliflozin. RESULTS: Clinically achievable concentrations of Canagliflozin, but not Dapagliflozin, inhibit cellular proliferation and clonogenic survival of prostate and lung cancer cells alone and in combination with ionizing radiation and the chemotherapy Docetaxel. Canagliflozin reduced glucose uptake, mitochondrial complex-I supported respiration, ATP, and lipogenesis while increasing the activating phosphorylation of AMPK. The overexpression of NDI1 blocked the anti-proliferative effects of Canagliflozin indicating reductions in mitochondrial respiration are critical for anti-proliferative actions. CONCLUSION: These data indicate that like the biguanide metformin, Canagliflozin not only lowers blood glucose but also inhibits complex-I supported respiration and cellular proliferation in prostate and lung cancer cells. These observations support the initiation of studies evaluating the clinical efficacy of Canagliflozin on limiting tumorigenesis in pre-clinical animal models as well epidemiological studies on cancer incidence relative to other glucose lowering therapies in clinical populations. PMID- 27689019 TI - Volumetric, relaxometric and diffusometric correlates of psychotic experiences in a non-clinical sample of young adults. AB - BACKGROUND: Grey matter (GM) abnormalities are robust features of schizophrenia and of people at ultra high-risk for psychosis. However the extent to which neuroanatomical alterations are evident in non-clinical subjects with isolated psychotic experiences is less clear. METHODS: Individuals (mean age 20 years) with (n = 123) or without (n = 125) psychotic experiences (PEs) were identified from a population-based cohort. All underwent T1-weighted structural, diffusion and quantitative T1 relaxometry MRI, to characterise GM macrostructure, microstructure and myelination respectively. Differences in quantitative GM structure were assessed using voxel-based morphometry (VBM). Binary and ordinal models of PEs were tested. Correlations between socioeconomic and other risk factors for psychosis with cortical GM measures were also computed. RESULTS: GM volume in the left supra-marginal gyrus was reduced in individuals with PEs relative to those with no PEs. The greater the severity of PEs, the greater the reduction in T1 relaxation rate (R1) across left temporoparietal and right pre frontal cortices. In these regions, R1 was positively correlated with maternal education and inversely correlated with general psychopathology. CONCLUSIONS: PEs in non-clinical subjects were associated with regional reductions in grey-matter volume reduction and T1 relaxation rate. The alterations in T1 relaxation rate were also linked to the level of general psychopathology. Follow up of these subjects should clarify whether these alterations predict the later development of an ultra high-risk state or a psychotic disorder. PMID- 27689020 TI - Influence of aerobic exercise training on the neural correlates of motor learning in Parkinson's disease individuals. AB - BACKGROUND: Aerobic exercise training (AET) has been shown to provide general health benefits, and to improve motor behaviours in particular, in individuals with Parkinson's disease (PD). However, the influence of AET on their motor learning capacities, as well as the change in neural substrates mediating this effect remains to be explored. OBJECTIVE: In the current study, we employed functional Magnetic Resonance Imaging (fMRI) to assess the effect of a 3-month AET program on the neural correlates of implicit motor sequence learning (MSL). METHODS: 20 healthy controls (HC) and 19 early PD individuals participated in a supervised, high-intensity, stationary recumbent bike training program (3 times/week for 12 weeks). Exercise prescription started at 20 min (+ 5 min/week up to 40 min) based on participant's maximal aerobic power. Before and after the AET program, participants' brain was scanned while performing an implicit version of the serial reaction time task. RESULTS: Brain data revealed pre-post MSL related increases in functional activity in the hippocampus, striatum and cerebellum in PD patients, as well as in the striatum in HC individuals. Importantly, the functional brain changes in PD individuals correlated with changes in aerobic fitness: a positive relationship was found with increased activity in the hippocampus and striatum, while a negative relationship was observed with the cerebellar activity. CONCLUSION: Our results reveal, for the first time, that exercise training produces functional changes in known motor learning related brain structures that are consistent with improved behavioural performance observed in PD patients. As such, AET can be a valuable non pharmacological intervention to promote, not only physical fitness in early PD, but also better motor learning capacity useful in day-to-day activities through increased plasticity in motor related structures. PMID- 27689021 TI - Direct estimation of patient attributes from anatomical MRI based on multi-atlas voting. AB - MRI brain atlases are widely used for automated image segmentation, and in particular, recent developments in multi-atlas techniques have shown highly accurate segmentation results. In this study, we extended the role of the atlas library from mere anatomical reference to a comprehensive knowledge database with various patient attributes, such as demographic, functional, and diagnostic information. In addition to using the selected (heavily-weighted) atlases to achieve high segmentation accuracy, we tested whether the non-anatomical attributes of the selected atlases could be used to estimate patient attributes. This can be considered a context-based image retrieval (CBIR) approach, embedded in the multi-atlas framework. We first developed an image similarity measurement to weigh the atlases on a structure-by-structure basis, and then, the attributes of the multiple atlases were weighted to estimate the patient attributes. We tested this concept first by estimating age in a normal population; we then performed functional and diagnostic estimations in Alzheimer's disease patients. The accuracy of the estimated patient attributes was measured against the actual clinical data, and the performance was compared to conventional volumetric analysis. The proposed CBIR framework by multi-atlas voting would be the first step toward a knowledge-based support system for quantitative radiological image reading and diagnosis. PMID- 27689022 TI - Longitudinal cerebellar diffusion tensor imaging changes in posterior fossa syndrome. AB - Posterior fossa syndrome is a severe transient loss of language that frequently complicates resection of tumors of the cerebellum. The associated pathophysiology and relevant anatomy to this language deficit remains controversial. We performed a retrospective analysis of all cerebellar tumor resections at Seattle Children's Hospital from 2010 to 2015. Diffusion tensor imaging was performed on each of the patients as part of their clinical scan. Patients included in the study were divided into groups based on language functioning following resection: intact (N = 19), mild deficit (N = 19), and posterior fossa syndrome (N = 9). Patients with posterior fossa syndrome showed white matter changes evidenced by reductions in fractional anisotropy in the left and right superior cerebellar peduncle following resection, and these changes were still evident 1-year after surgery. These changes were greater in the superior cerebellar peduncle than elsewhere in the cerebellum. Prior to surgery, posterior fossa patients did not show changes in fractional anisotropy however differences were observed in mean and radial diffusivity measures in comparison to other groups which may provide a radiographic marker of those at greatest risk of developing post-operative language loss. PMID- 27689023 TI - Human case of bacteremia due to Streptococcus suis serotype 5 in Japan: The first report and literature review. AB - Streptococcus suis is a zoonotic pathogen that can be transferred from pigs to humans. The serotypes 2 and 14 are prevalent among patients with S. suis infections, while other serotypes (i.e., 1, 4, 5, 16, and 24) have been detected in rare human cases. To the best of our knowledge, the present patient handling with raw pork is the first human case of uncomplicated bacteremia due to S. suis serotype 5 in Japan. We confirmed the new sequence type 752 of this isolate. Virulence-associated gene profiling was performed; both sly (encoding the hemolysin suilysin) and mrp (encoding a muramidase-released protein) were detected without amplification of epf (encoding the extracellular factor). Our polymerase chain reaction-based results indicated that this isolate possessed both tet(O), the tetracycline-resistance determinant, and erm(B), the macrolide/lincosamide-resistance determinant. In addition, we provide the review of literature concerning clinical and microbiological features of four human cases of infection due to S. suis serotype 5. Clinicians should be aware of this microorganism when examining and treating patients with fever, who are handling raw pork or having close contact with infected pigs even if they are immunocompetent. PMID- 27689024 TI - (123)I-Meta-iodobenzylguanidine Sympathetic Imaging: Standardization and Application to Neurological Diseases. AB - (123)I-meta-iodobenzylguanidine (MIBG) has become widely applied in Japan since its introduction to clinical cardiology and neurology practice in the 1990s. Neurological studies found decreased cardiac uptake of (123)I-MIBG in Lewy-body diseases including Parkinson's disease and dementia with Lewy bodies. Thus, cardiac MIBG uptake is now considered a biomarker of Lewy body diseases. Although scintigraphic images of (123)I-MIBG can be visually interpreted, an average count ratio of heart-to-mediastinum (H/M) has commonly served as a semi-quantitative marker of sympathetic activity. Since H/M ratios significantly vary according to acquisition and processing conditions, quality control should be appropriate, and quantitation should be standardized. The threshold H/M ratio for differentiating Lewy-body disease is 2.0-2.1, and was based on standardized H/M ratios to comparable values of medium-energy collimators. Parkinson's disease can be separated from various types of parkinsonian syndromes using cardiac (123)I-MIBG, whereas activity is decreased on images of Lewy-body diseases using both (123)I ioflupane for the striatum and (123)I-MIBG. Despite being a simple index, the H/M ratio of (123)I-MIBG uptake is reproducible and can serve as an effective tool to support a diagnosis of Lewy-body diseases in neurological practice. PMID- 27689025 TI - Circulating Tumor Cell and Cell-free Circulating Tumor DNA in Lung Cancer. AB - Circulating tumor cells (CTCs) are tumor cells that are separated from the primary site or metastatic lesion and disseminate in blood circulation. CTCs are considered to be part of the long process of cancer metastasis. As a 'liquid biopsy', CTC molecular examination and investigation of single cancer cells create an important opportunity for providing an understanding of cancer biology and the process of metastasis. In the last decade, we have seen dramatic development in defining the role of CTCs in lung cancer in terms of diagnosis, genomic alteration determination, treatment response and, finally, prognosis prediction. The aims of this review are to understand the basic biology and to review methods of detection of CTCs that apply to the various types of solid tumor. Furthermore, we explored clinical applications, including treatment monitoring to anticipate therapy resistance as well as biomarker analysis, in the context of lung cancer. We also explored the potential use of cell-free circulating tumor DNA (ctDNA) in the genomic alteration analysis of lung cancer. PMID- 27689026 TI - Second Generation Antipsychotics in the Treatment of Major Depressive Disorder: An Update. AB - Less than one third of patients who suffer from major depressive disorder (MDD) report remission following antidepressant treatments requiring more diverse treatment approaches. Augmentation of second generation antipsychotics (SGAs) has been increasingly recognized as an important treatment option. The authors have previously provided a comprehensive review of SGAs for the treatment of MDD in 2013. Since then, numerous additional clinical trials have been conducted to investigate diverse issues regarding the utility of SGAs in MDD. Moreover, a new SGA, brexpiprazole, was recently approved by the Food and Drug Administration in July 2015 for the treatment of MDD as an augmentation agent to antidepressants. Thus, the aim of this study was to provide a concise update of all the available SGAs for the treatment of MDD, in particular on the additional clinical trials which have been published since 2013. PMID- 27689027 TI - Targeted Cancer Therapy Using Engineered Salmonella typhimurium. AB - Obligate or facultative anaerobic bacteria such as Bifidobacterium, Clostridium, Salmonella, or Escherichia coli specifically colonize and proliferate inside tumor tissues and inhibit tumor growth. Among them, attenuated Salmonella typhimurium (S. typhimurium) has been widely studied in animal cancer models and Phase I clinical trials in human patients. S. typhimurium genes are easily manipulated; thus diverse attenuated strains of S. typhimurium have been designed and engineered as tumor-targeting therapeutics or drug delivery vehicles that show both an excellent safety profile and therapeutic efficacy in mouse models. An attenuated strain of S. typhimurium, VNP20009, successfully targeted human metastatic melanoma and squamous cell carcinoma in Phase I clinical trials; however, the efficacy requires further refinement. Along with the characteristics of self-targeting, proliferation, and deep tissue penetration, the ease of genetic manipulation allows for the production of more attenuated strains with greater safety profiles and vector systems that deliver designable cargo molecules for cancer diagnosis and/or therapy. Here, we discuss recent progress in the field of Salmonellae-mediated cancer therapy. PMID- 27689028 TI - Cutaneous Melanoma in Asians. AB - Malignant melanoma is a rare disease in Asians but potentially the most aggressive form of skin cancer worldwide. It can occur in any melanocyte containing anatomic site. Four main cutaneous melanoma subtypes are recognized: lentigo maligna melanoma, superficial spreading melanoma, acral lentiginous melanoma (ALM), and nodular melanoma. Generally, excessive exposure to ultraviolet (UV) radiation increases the risk of melanoma. The exception is ALM, which is the most common melanoma subtype in Asians and is not associated with UV radiation. ALM presents as dark brownish to black, irregular maculopatches, nodules, or ulcers on the palms, soles, and nails. The lesions may be misdiagnosed as more benign lesions, such as warts, ulcers, hematomas, foreign bodies, or fungal infections, especially in amelanotic acral melanomas where black pigments are absent. The aim of this brief review is to improve understanding and the rate of early detection thereby reducing mortality, especially regarding cutaneous melanoma in Asians. PMID- 27689029 TI - Clinical Usefulness of Spectral-Domain Optical Coherence Tomography in Glaucoma and NAION. AB - The development of optical coherence tomography (OCT) has changed the clinical management of ophthalmic diseases by furthering the understanding of pathogenesis, as well as improving the monitoring of their progression and assisting in quantifying the response to treatment modalities in ophthalmic diseases. Initially, the two-dimensional configuration of the optic nerve head (ONH) and the thickness of the retinal nerve fiber layer (RNFL) were the main OCT structural parameters used in clinical management of optic nerve diseases. Now, with higher resolution power and faster acquisition times, the details of ONH and the retina including the macular area can be measured using spectral domain OCT (SD-OCT) with high reproducibility and increased diagnostic ability. OCT can provide structural information to improve the understanding and management of optic nerve diseases. In this review, we will briefly summarize the clinical applications of SD-OCT in glaucoma and nonarteritic anterior ischemic optic neuropathy, which are two representative optic nerve diseases. PMID- 27689030 TI - Peroxisome Proliferator-Activated Receptor-gammaGene Expression and Its Association with Oxidative Stress in Patients with Metabolic Syndrome. AB - Regulation of the peroxisome proliferator-activated receptor-gamma (PPAR-gamma) gene plays an important role in controlling the metabolism of lipids and inflammatory processes. Therefore, it can be associated with the pathogenesis of metabolic syndrome (MetS). The purpose of this study was to determine the expression of this gene in peripheral blood mononuclear cells (PBMC) in patients with metabolic syndrome. Using real-time polymerase chain reaction (PCR), mRNA expression of PPAR-gamma was found in PBMC from 37 subjects with MetS and 30 healthy controls. Serum levels of glucose and lipid profiles were measured. The total antioxidant capacity (TAC) was measured using the ferric reducing ability of plasma (FRAP) test. Malondialdehyde (MDA) was determined using a fluorimetric method. Total oxidant status (TOS) in serum was assayed according to oxidation of ferric to ferrous in the presence of methyl orange. Super oxide dismutase (SOD) activity was measured using a Randox kit. Expression of PPAR-gamma gene was significantly increased in patients with MetS compared to the control subjects (p=0.002). There was no difference in serum levels of TAC, MDA and SOD between the two study groups, but a significant difference was observed in the TOS (p=0.03). Serum levels of triglycerides and glucose were significantly higher in subjects with MetS. According to the results of our study, an increase in the expression of PPAR-gamma in subjects with MetS indicated a possible role of PPAR gamma in the pathogenesis of this disease. PMID- 27689031 TI - Diagnosis and Management of Pediatric and Adolescent Varicocele: A Survey of Pediatric Urologists in Korea. AB - The aim of this study was to evaluate current practice patterns on diagnosis and management of pediatric varicoceles. Questionnaires of approaches to diagnosis and management of pediatric varicoceles were sent electronically to pediatric urologists. Of the 70 questionnaires e-mailed, 37 (53%) responded to the survey. 10 respondents (27%) chose to operate on varicoceles, whereas 9 (24%) chose to observe, and 18 (49%) chose to decide upon treatment depending on the clinical situation. The most important indication for varicocelectomy was a decrease in ipsilateral testicular size (n=29, 78%) followed by testicular or scrotal pain (n=4, 11%) and varicocele grade (n=4, 11%). The optimal age for varicocelectomy was answered as 13.8+/-2.3 years mean. 32 respondents (86%) have used ultrasonography to aid in the diagnosis of varicoceles, and 26 respondents (70%) have considered repairing varicocele incidentally detected on ultrasonography. In an otherwise asymptomatic patient with varicocele, 17 respondents (46%) considered surgery for grade 3, but 15 respondents (41%) would not repair the varicocele. The most commonly used surgical approach was subinguinal microsurgical (n=19, 51%), followed by inguinal (n=9, 24%) and laparascopic (n=5, 14%) procedures. The most commonly experienced post-operative complication was recurrence (n=22, 59%) followed by persistence (n=13, 35%) and hydrocele (n=10, 27%). 28 respondents (76%) did not have long-term follow-up data including regarding fertility on their varicocele patients. Our survey demonstrates that there is lack of consensus on diagnosis and management of pediatric and adolescent varicoceles among pediatric urologists. A prospective randomized study of pediatric and adolescent varicoceles is needed to assess the outcomes and develop universal management guidelines. PMID- 27689033 TI - Extreme Metabolic Alkalosis Caused by Gastrostomy Tube Malposition Treated Using Conventional Hemodialysis. PMID- 27689032 TI - Association between Vitamin D Status and Risk of Peripheral Arterial Disease: The Dong-gu Study. AB - Low levels of vitamin D have been associated with increased cardiovascular disease risk. However, few studies have evaluated the association between vitamin D status and peripheral arterial disease (PAD). We therefore aimed to investigate whether low 25-hydroxyvitamin D (25(OH)D) levels were associated with increased risk of PAD in the Korean population. This cross-sectional study was conducted among 8,960 subjects aged 50 years or older without known myocardial infarction or stroke. PAD was defined by an ankle brachial blood pressure index <0.9. Multivariate logistic regression was used to evaluate the association between serum 25(OH)D levels and risk of PAD. Of the 8,960 subjects, 3.0% had PAD and the age and sex adjusted prevalence of PAD decreased with the increasing 25(OH)D quartile. After adjusting for potential confounders and parathyroid hormones, serum 25(OH)D levels were associated with a significantly decreased risk of PAD (OR for one SD increase, 0.98; 95% CI, 0.95-1.0, P for trend=0.040). Compared with the first 25(OH)D quartile, the odds of PAD were 0.86 (95% CI, 0.62-1.21), 0.67 (95% CI, 0.46-0.97), and 0.71 (95% CI, 0.49-1.04) for the second, third, and fourth quartiles, respectively. In this cross-sectional study, we found that low serum 25(OH)D levels were associated with an increased risk of PAD, independent of traditional cardiovascular risk factors and parathyroid hormone. Our findings suggest that low vitamin D levels may contribute to PAD in the Korean population. PMID- 27689034 TI - A Case of Acute Pyelonephritis in Bilateral Renal Malrotation. PMID- 27689035 TI - The meaning of anti-Mullerian hormone levels in patients at a high risk of poor ovarian response. AB - Measurements of ovarian reserve play an important role in predicting the clinical results of assisted reproductive technology (ART). The ideal markers of ovarian reserve for clinical applications should have high specificity in order to determine genuine poor responders. Basal follicle-stimulating hormone levels, antral follicle count, and serum anti-Mullerian hormone (AMH) levels have been suggested as ovarian reserve tests that may fulfill this requirement, with serum AMH levels being the most promising parameter. Serum AMH levels have been suggested to be a predictor of clinical pregnancy in ART for older women, who are at a high risk for decreased ovarian response. We reviewed the prognostic significance of ovarian reserve tests for patients undergoing ART treatment, with a particular focus on the significance of serum AMH levels in patients at a high risk of poor ovarian response. PMID- 27689036 TI - Comparison of static culture, micro-vibration culture, and micro-vibration culture with co-culture in poor ovarian responders. AB - OBJECTIVE: This study was conducted to compare the effects of static culture, dynamic culture, and the combination of dynamic culture with specialized surfaces involving co-culture on human embryonic development. Embryos cultured using conventional static culture (SC) techniques served as a control group. We compared dynamic culture using micro-vibration culture (MVC) and micro-vibration with co-culture (MCoC), in which autologous cumulus cells were used as a specialized surface. METHODS: We conducted a chart review of patients who were treated between January 2011 and November 2014 in order to compare embryonic development rates and pregnancy rates among the groups. Zygotes were cultured in micro-droplets, and embryos were subsequently selected for transfer. Some surplus embryos were cryopreserved, and the others were cultured for blastocyst development. A micro-vibrator was set at the frequency of 42 Hz for duration of 5 seconds per 60 minutes to facilitate embryo development. RESULTS: No significant differences among the groups were present in patient's characteristics. However, the clinical pregnancy rates were significantly higher in the MVC group and the MCoC group than in the SC group. No significant differences were found in the blastocyst development rate between the SC group and the MVC group, but the blastocyst development rate in the MCoC group was significantly higher than in the SC and MVC groups. CONCLUSION: The clinical pregnancy rate was significantly increased by the application of micro-vibration to the embryonic cultures of poor responders. The blastocyst development rate was significantly increased by the application of MCoC to surplus embryos. PMID- 27689037 TI - The effect of the site of laser zona opening on the complete hatching of mouse blastocysts and their cell numbers. AB - OBJECTIVE: We studied the effect of the site of laser zona opening on the complete hatching of mouse blastocysts and the cell numbers of the completely hatched blastocysts. METHODS: Mouse blastocysts were randomly allocated to the inner cell mass (ICM) group (zona opening performed at the site of the ICM, n=125), the trophectoderm (TE) group (zona opening performed opposite to the ICM, n=125) and the control group (no zona opening, n=125). RESULTS: The rate of complete hatching of the blastocysts was not significantly different in the ICM and the TE group (84.8% vs 80.8%, respectively; p=0.402), but was significantly lower in the control group (51.2%, p<0.001). The cell numbers in the completely hatched blastocysts were comparable in the control group, the ICM group, and the TE group (69+/-19.3, 74+/-15.7, and 71+/-16.8, respectively; p=0.680). CONCLUSION: These findings indicate that the site of laser zona opening did not influence the rate of complete hatching of mouse blastocysts or their cell numbers. PMID- 27689038 TI - Percentage of motile spermatozoa at 22 hours after swim-up procedure: An indicator for intracytoplasmic sperm injection? AB - OBJECTIVE: The decision to use in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), or split insemination (IVF-ICSI) in the first cycle is based on the number of motile sperm. Hence, total fertilization failure (TFF) often occurs during IVF cycles, despite normozoospermia. To investigate whether the cumulative motile swim-up spermatozoa percentage at 22 hours post insemination (MSPPI) is an indicator for ICSI, we analyzed TFF, fertilization, blastocyst development, chemical pregnancy, clinical pregnancy, and live birth rates. METHODS: This prospective study was performed using data obtained from 260 IVF cycles. At 22 hours after insemination, the remaining swim-up spermatozoa were observed and divided into six groups according to MSPPI (<10%, 10% to <30%, 30% to <50%, 50% to <70%, 70% to <90%, and 90% to 100%). RESULTS: Regardless of the ejaculated motile sperm concentration (0.6-280*10(6)/mL motile spermatozoa), the incidence of TFF significantly increased when MSPPI was <10%, and the fertilization rate significantly decreased when MSPPI was <30%. We found that cumulative MSPPI correlated with the cumulative fertilization rate (Spearman correlation, 0.508, p<0.001). Regarding embryo development, we observed no significant differences in the rates of blastocyst development, chemical pregnancy, clinical pregnancy, or live birth among all groups. CONCLUSION: Our findings suggest that MSPPI is a viable indicator for split IVF-ICSI and ICSI. Taken together, by employing the MSPPI test in advance before IVF, ICSI, or split IVF-ICSI cycles, unnecessary split IVF-ICSI and ICSI may be avoided. PMID- 27689039 TI - Clinical outcomes of single versus double blastocyst transfer in fresh and vitrified-warmed cycles. AB - OBJECTIVE: Assisted reproductive technology has been associated with an increase in multiple pregnancies. The most effective strategy for reducing multiple pregnancies is single embryo transfer. Beginning in October 2015, the National Supporting Program for Infertility in South Korea has limited the number of embryos that can be transferred per in vitro fertilization (IVF) cycle depending on the patient's age. However, little is known regarding the effect of age and number of transferred embryos on the clinical outcomes of Korean patients. Thus, this study was performed to evaluate the effect of the number of transferred blastocysts on clinical outcomes. METHODS: This study was carried out in the Fertility Center of CHA Gangnam Medical Center from January 2013 to December 2014. The clinical outcomes of 514 women who underwent the transfer of one or two blastocysts on day 5 after IVF and of 721 women who underwent the transfer of one or two vitrified-warmed blastocysts were analyzed retrospectively. RESULTS: For both fresh and vitrified-warmed cycles, the clinical pregnancy rate and live birth or ongoing pregnancy rate were not significantly different between patients who underwent elective single blastocyst transfer (eSBT) and patients who underwent double blastocyst transfer (DBT), regardless of age. However, the multiple pregnancy rate was significantly lower in the eSBT group than in the DBT group. CONCLUSION: The clinical outcomes of eSBT and DBT were equivalent, but eSBT had a lower risk of multiple pregnancy and is, therefore, the best option. PMID- 27689040 TI - Pregnancy rate in women with adenomyosis undergoing fresh or frozen embryo transfer cycles following gonadotropin-releasing hormone agonist treatment. AB - OBJECTIVE: To determine the preferred regimen for women with adenomyosis undergoing in vitro fertilization (IVF), we compared the IVF outcomes of fresh embryo transfer (ET) cycles with or without gonadotropin-releasing hormone (GnRH) agonist pretreatment and of frozen-thawed embryo transfer (FET) cycles following GnRH agonist treatment. METHODS: This retrospective study included 241 IVF cycles of women with adenomyosis from January 2006 to January 2012. Fresh ET cycles without (147 cycles, group A) or with (105 cycles, group B) GnRH agonist pretreatment, and FET cycles following GnRH agonist treatment (43 cycles, group C) were compared. Adenomyosis was identified by using transvaginal ultrasound at the initial workup and classified into focal and diffuse types. The IVF outcomes were also subanalyzed according to the adenomyotic region. RESULTS: GnRH agonist pretreatment increased the stimulation duration (11.5+/-2.1 days vs. 9.9+/-2.0 days) and total dose of gonadotropin (3,421+/-1,141 IU vs. 2,588+/-1,192 IU), which resulted in a significantly higher number of retrieved oocytes (10.0+/-8.2 vs. 7.9+/-6.8, p=0.013) in group B than in group A. Controlled ovarian stimulation for freezing resulted in a significantly higher number of retrieved oocytes (14.3+/-9.2 vs. 10.0+/-8.2, p=0.022) with a lower dose of gonadotropin (2,974+/-1,112 IU vs. 3,421+/-1,141 IU, p=0.037) in group C than in group B. The clinical pregnancy rate in group C (39.5%) tended to be higher than those in groups B (30.5%) and A (25.2%) but without a significant difference. CONCLUSION: FET following GnRH agonist pretreatment tended to increase the pregnancy rate in patients with adenomyosis. Further large-scale prospective studies are required to confirm this result. PMID- 27689041 TI - Psychological distress and fertility quality of life (FertiQoL) in infertile Korean women: The first validation study of Korean FertiQoL. AB - OBJECTIVE: To investigate psychological distress and fertility quality of life (FertiQoL) in infertile Korean women, and to investigate whether a correlation exists between psychological distress and FertiQoL. METHODS: Participants in this study were made up of 141 infertile women and 65 fertile women. We conducted a survey on psychological distress (using the Depression Anxiety Stress Scales [DASS]-42 questionnaire) and administered a FertiQoL questionnaire. The levels of stress hormones (adrenocorticotropic hormone [ACTH] and cortisol) in serum were assessed. RESULTS: The scores for depression (13.7+/-8.4), anxiety (10.7+/-6.4), and stress (18.0+/-8.3) among the infertile women were significantly higher than the scores for depression (9.4+/-7.5), anxiety (6.6+/-6.0), and stress (12.2+/ 8.3, p<0.001) among the fertile women. There was no difference in the scores for depression (13.5+/-8.2, 13.8+/-8.6), anxiety (10.0+/-6.2, 11.5+/-6.6) and stress (17.7+/-8.4, 18.4+/-8.1) between younger (<=34) and older (>=35) participants. The mind-body (r =-0.495) and emotional (r =-0.590) subscales showed a higher negative correlation with stress compared with other scales of psychological distress. At the same time, the social (r =-0.537) and relational (r =-0.385) subscales showed a higher negative correlation with depression. Levels of cortisol and ACTH in infertile women were 9.1 ug/mL and 11.9 pg/mL, respectively, which are within normal ranges. CONCLUSION: The levels of psychological distress and quality of life in infertile Korean women seem to require psychological intervention. This study provides a baseline measurement of psychological distress and FertiQoL in infertile women in Korea, which will be available for developing psychological interventions for infertile Korean women. PMID- 27689042 TI - Live birth in a woman with recurrent implantation failure and adenomyosis following transfer of refrozen-warmed embryos. AB - The aim was to report a healthy live birth using re-vitrified-warmed cleavage stage embryos derived from supernumerary warmed embryos after frozen embryo transfer (ET) in a patient with recurrent implantation failure (RIF). The case was a 39-year-old female with a history of polycystic ovarian syndrome and adenomyosis, along with RIF. After ovarian hyperstimulation, 33 cumulus-oocyte complexes were retrieved and fertilized with conventional in vitro fertilization and intracytoplasmic sperm injection. Because of the risk of ovarian hyperstimulation syndrome, 16 grade B and C embryos were vitrified. After 3 and 6 months, 3 and 4 B-C warmed embryos were transferred to the uterus, respectively. However, implantation did not take place. Ten months later, four embryos were warmed, two grade B 8-cell embryos were transferred, and two embryos were re vitrified. One year later, the two re-vitrified cleavage-stage embryos were warmed, which resulted in a successful live birth. This finding showed that following first warming, it is feasible to refreeze supernumerary warmed embryos for subsequent ET in patients with a history of RIF.

PMID- 27689045 TI - The Efficacy and Safety of Tetrachlorodecaoxide in Comparison with Super-oxidised Solution in Wound Healing. AB - BACKGROUND: Some of the relatively newer, more efficacious, and potent topical wound dressing solutions include tetrachlorodecaoxide and super-oxidised solution. This study compares the efficacy and safety of these two drugs. METHODS: This is a block-randomised, double blind, parallel-arm, post-marketing study. One hundred fifty patients with ulcers (75 blocks uniform for sex, ulcer aetiology, diabetes mellitus, and wound area score) were randomised into the two treatment arms. Patients were observed for eight weeks with weekly assessments. One hundred and twenty patients completed the study. Wound healing was objectively assessed by measurement of wound area, scoring of wound exudation and tissue type, and using the pressure ulcer scale of healing Tool (validated for multiple wound aetiologies). Subjective improvement in pain was noted using a visual analogue scale. Both groups were compared using Mann-Whitney U test on all indicators. RESULTS: Difference in change in wound tissue type in the two groups was significant (alpha=0.05) by intention-to-treat (ITT) and per-protocol (PP) analysis at the end of week two (ITT and PP, P<0.001) and week four (ITT, P=0.010; PP, P=0.009). P-values for other comparisons were not significant (P>0.05). No study-related adverse events were observed. CONCLUSIONS: Both drugs are efficacious. Tetrachlorodecaoxide yields healthy granulation tissue earlier. Both drugs appear to be safe for application. PMID- 27689046 TI - Informed Consent as a Litigation Strategy in the Field of Aesthetic Surgery: An Analysis Based on Court Precedents. AB - BACKGROUND: In an increasing number of lawsuits doctors lose, despite providing preoperative patient education, because of failure to prove informed consent. We analyzed judicial precedents associated with insufficient informed consent to identify judicial factors and trends related to aesthetic surgery medical litigation. METHODS: We collected data from civil trials between 1995 and 2015 that were related to aesthetic surgery and resulted in findings of insufficient informed consent. Based on these data, we analyzed the lawsuits, including the distribution of surgeries, dissatisfactions, litigation expenses, and relationship to informed consent. RESULTS: Cases were found involving the following types of surgery: facial rejuvenation (38 cases), facial contouring surgery (27 cases), mammoplasty (16 cases), blepharoplasty (29 cases), rhinoplasty (21 cases), body-contouring surgery (15 cases), and breast reconstruction (2 cases). Common reasons for postoperative dissatisfaction were deformities (22%), scars (17%), asymmetry (14%), and infections (6%). Most of the malpractice lawsuits occurred in Seoul (population 10 million people; 54% of total plastic surgeons) and in primary-level local clinics (113 cases, 82.5%). In cases in which only invalid informed consent was recognized, the average amount of consolation money was KRW 9,107,143 (USD 8438). In cases in which both violation of non-malfeasance and invalid informed consent were recognized, the average amount of consolation money was KRW 12,741,857 (USD 11,806), corresponding to 38.6% of the amount of the judgment. CONCLUSIONS: Surgeons should pay special attention to obtaining informed consent, because it is a double-edged sword; it has clinical purposes for doctors and patients but may also be a litigation strategy for lawyers. PMID- 27689047 TI - The Measurement of the Sensory Recovery Period in Zygoma and Blow-Out Fractures with Neurometer Current Perception Threshold. AB - BACKGROUND: Facial hypoesthesia is one of the most troublesome complaints in the management of facial bone fractures. However, there is a lack of literature on facial sensory recovery after facial trauma. The purpose of this study was to evaluate the facial sensory recovery period for facial bone fractures using Neurometer. METHODS: Sixty-three patients who underwent open reduction of zygomatic and blowout fractures between December 2013 and July 2015 were included in the study. The facial sensory status of the patients was repeatedly examined preoperatively and postoperatively by Neurometer current perception threshold (CPT) until the results were normalized. RESULTS: Among the 63 subjects, 30 patients had normal Neurometer results preoperatively and postoperatively. According to fracture types, 17 patients with blowout fracture had a median recovery period of 0.25 months. Twelve patients with zygomatic fracture had a median recovery period of 1.00 month. Four patients with both fracture types had a median recovery period of 0.625 months. The median recovery period of all 33 patients was 0.25 months. There was no statistically significant difference in the sensory recovery period between types and subgroups of zygomatic and blowout fractures. In addition, there was no statistically significant difference in the sensory recovery period according to Neurometer results and the patients' own subjective reports. CONCLUSIONS: Neurometer CPT is effective for evaluating and comparing preoperative and postoperative facial sensory status and evaluating the sensory recovery period in facial bone fracture patients. PMID- 27689048 TI - Feasibility of the Use of RapiGraft and Skin Grafting in Reconstructive Surgery. AB - BACKGROUND: Skin grafting is a relatively simple and thus widely used procedure. However, the elastic and structural quality of grafted skin is poor. Recently, various dermal substitutes have been developed to overcome this disadvantage of split-thickness skin grafts. The present study aims to determine the feasibility of RapiGraft as a new dermal substitute. METHODS: This prospective study included 20 patients with partial- or full-thickness skin defects; the patients were enrolled between January 2013 and March 2014. After skin defect debridement, the wound was divided into two parts by an imaginary line. Split-thickness skin grafting alone was performed on one side (group A), and RapiGraft and split thickness skin grafting were used on the other side (group B). All patients were evaluated using photographs and self-questionnaires. The Manchester scar scale (MSS), a chromameter, and a durometer were used for the scar evaluation. The average follow-up period was 6 months. RESULTS: The skin graft take rates were 93% in group A and 89% in group B, a non-significant difference (P=0.082). Statistically, group B had significantly lower MSS, vascularity, and pigmentation results than group A (P<0.05 for all). However, the groups did not differ significantly in pliability (P=0.155). CONCLUSIONS: The present study indicates that a simultaneous application of RapiGraft and a split-thickness skin graft is safe and yields improved results. Therefore, we conclude that the use of RapiGraft along with skin grafting will be beneficial for patients requiring reconstructive surgery. PMID- 27689049 TI - Acellular Dermal Matrix as a Core Strut for Projection in Nipple Reconstruction: Approaches for Three Different Methods of Breast Reconstruction. AB - BACKGROUND: The objective of this paper was to describe a novel technique for improving the maintenance of nipple projection in primary nipple reconstruction by using acellular dermal matrix as a strut in one of three different configurations, according to the method of prior breast reconstruction. The struts were designed to best fill the different types of dead spaces in nipple reconstruction depending on the breast reconstruction method. METHODS: A total of 50 primary nipple reconstructions were performed between May 2012 and May 2015. The prior breast reconstruction methods were latissimus dorsi (LD) flap (28 cases), transverse rectus abdominis myocutaneous (TRAM) flap (10 cases), or tissue expander/implant (12 cases). The nipple reconstruction technique involved the use of local flaps, including the C-V flap or star flap. A 1*2-cm acellular dermal matrix was placed into the core with O-, I-, and L-shaped struts for prior LD, TRAM, and expander/implant methods, respectively. The projection of the reconstructed nipple was measured at the time of surgery and at 3, 6, and 9 months postoperatively. RESULTS: The nine-month average maintenance of nipple projection was 73.0%+/-9.67% for the LD flap group using an O-strut, 72.0%+/ 11.53% for the TRAM flap group using an I-strut, and 69.0%+/-10.82% for the tissue expander/implant group using an L-strut. There were no cases of infection, wound dehiscence, or flap necrosis. CONCLUSIONS: The application of an acellular dermal matrix with a different kind of strut for each of 3 breast reconstruction methods is an effective addition to current techniques for improving the maintenance of long-term projection in primary nipple reconstruction. PMID- 27689051 TI - Clinical Experiences with the Scapular Fascial Free Flap. AB - BACKGROUND: The goal of reconstruction is to provide coverage of exposed vital structures with well-vascularized tissue for optimal restoration of form and function. Here, we present our clinical experience with the use of the scapular fascial free flap to correct facial asymmetry and to reconstruct soft tissue defects of the extremities. METHODS: We used a scapular fascial free flap in 12 cases for soft tissue coverage of the extremities or facial soft tissue augmentation. RESULTS: The flaps ranged in size from 3*12 to 13*23 cm. No cases of total loss of the flap occurred. Partial loss of the flap occurred in 1 patient, who was treated with a turnover flap using the adjacent scapular fascial flap and a skin graft. Partial loss of the skin graft occurred in 4 patients due to infection or hematoma beneath the graft, and these patients underwent another skin graft. Four cases of seroma at the donor site occurred, and these cases were treated with conservative management or capsulectomy and quilting sutures. CONCLUSIONS: The scapular fascial free flap has many advantages, including a durable surface for restoration of form and contours, a large size with a constant pedicle, adequate surface for tendon gliding, and minimal donor-site scarring. We conclude that despite the occurrence of a small number of complications, the scapular fascial free flap should be considered to be a viable option for soft tissue coverage of the extremities and facial soft tissue augmentation. PMID- 27689050 TI - Three-Dimensional Surface Imaging is an Effective Tool for Measuring Breast Volume: A Validation Study. AB - BACKGROUND: Accurate breast volume assessment is a prerequisite to preoperative planning, as well as intraoperative decision making in breast reconstruction surgery. The use of three-dimensional surface imaging (3D scanning) to assess breast volume has many advantages. However, before employing 3D scanning in the field, the tool's validity should be demonstrated. The purpose of this study was to confirm the validity of 3D-scanning technology for evaluating breast volume. METHODS: We reviewed the charts of 25 patients who underwent breast reconstruction surgery immediately after total mastectomy. Breast volumes using the Axis Three 3D scanner, water-displacement technique, and magnetic resonance imaging (MRI) were obtained bilaterally in the preoperative period. During the operation, the tissue removed during total mastectomy was weighed and the specimen volume was calculated from the weight. Then, we compared the volume obtained from 3D scanning with those obtained using the water-displacement technique, MRI, and the calculated volume of the tissue removed. RESULTS: The intraclass correlation coefficient (ICC) of breast volumes obtained from 3D scanning, as compared to the volumes obtained using the water-displacement technique and specimen weight, demonstrated excellent reliability. The ICC of breast volumes obtained using 3D scanning, as compared to those obtained by MRI, demonstrated substantial reliability. Passing-Bablok regression showed agreement between 3D scanning and the water-displacement technique, and showed a linear association of 3D scanning with MRI and specimen volume, respectively. CONCLUSIONS: When compared with the classical water-displacement technique and MRI-based volumetry, 3D scanning showed significant reliability and a linear association with the other two methods. PMID- 27689052 TI - Reconstruction of Large Defects in the Perineal Area Using Multiple Perforator Flaps. AB - BACKGROUND: Perineal defects are commonly encountered during the treatment of conditions such as malignancy, infectious disease, and trauma. Covering large defects in the perineal area is challenging due to its complicated anatomy and the need for functional preservation. METHODS: Fourteen patients who underwent reconstructive surgery with multiple perforator flaps for defects >100 cm(2) in the perineal area were included in this retrospective cohort study. Characteristics of the perforator flap operation and postoperative outcomes were reviewed. RESULTS: Reconstruction was performed using 2 perforator flaps for 13 patients and 3 perforator flaps for 1 patient. Internal pudendal artery perforator flaps were mainly used for covering the defects. The average defect size was 176.3+/-61.8 cm(2) and the average size of each flap was 95.7+/-31.9 cm(2). Six patients had minor complications, such as wound dehiscence and partial necrosis of the flap margin, which were corrected with simple revision procedures. CONCLUSIONS: Multiple perforator flaps can be used to achieve successful reconstructions of large perineal defects that are difficult to reconstruct with other coverage methods. PMID- 27689053 TI - Rhinoplasty Education Using a Standardized Patient Encounter. AB - BACKGROUND: Comprehensive aesthetic surgery training continues to be a challenge for residency programs. Our residency program developed a rhinoplasty-based objective structured clinical examination (OSCE) based upon validated methods as part of the residency education curriculum. We report our experience with the rhinoplasty-based OSCE and offer guidance to its incorporation within residency programs. METHODS: The encounter involved resident evaluation and operative planning for a standardized patient desiring a rhinoplasty procedure. Validated OSCE methods currently used at our medical school were implemented. Residents were evaluated on appropriate history taking, physical examination, and explanation to the patient of treatment options. Examination results were evaluated using analysis of variance (statistical significance P<0.05). RESULTS: Twelve residents completed the rhinoplasty OSCE. Medical knowledge assessment showed increasing performance with clinical year, 50% versus 84% for postgraduate year 3 and 6, respectively (P<0.005). Systems-based practice scores showed that all residents incorrectly submitted forms for billing and operative scheduling. All residents confirmed that the OSCE realistically represents an actual patient encounter. All faculty confirmed the utility of evaluating resident performance during the OSCE as a useful assessment tool for determining the Next Accreditation System Milestone level. CONCLUSIONS: Aesthetic surgery training for residents will require innovative methods for education. Our examination showed a program-educational weakness in billing/coding, an area that will be improved upon by topic-specific lectures. A thoroughly developed OSCE can provide a realistic educational opportunity to improve residents' performance on the nonoperative aspects of rhinoplasty and should be considered as an adjunct to resident education. PMID- 27689054 TI - Immediate Bilateral Breast Reconstruction with Unilateral Deep Superior Epigastric Artery and Superficial Circumflex Iliac Artery Flaps. AB - Autologous breast reconstruction utilizing a perforator flap is an increasingly popular method for reducing donor site morbidity and implant-related complications. However, aberrant anatomy not readily visible on computed tomography angiography is a rare albeit real risk when undergoing perforator flap reconstruction. We present an operative case of a patient who successfully underwent a bilateral breast reconstruction sourced from a unilateral abdominal flap divided into deep superior epigastric artery and superficial circumflex iliac artery flap segments. PMID- 27689056 TI - A Simple, Reliable, and Inexpensive Intraoperative External Expansion System for Enhanced Autologous Structural Fat Grafting. AB - External volume expansion of the recipient site by suction has been proposed as a way of improving fat graft survival. The objective of this study was to present an innovative and simple intraoperative external expansion system to enhance small-volume autologous fat grafting (40-80 mL) and to discuss its background and its mechanism of action. In this system, expansion is performed using a complete vacuum delivery system known as the Kiwi VAC-6000M with a PalmPump (Clinical Innovations). The recipient site is rapidly expanded intraoperatively 10 times for 30 seconds each with a negative pressure of up to 550 mm Hg before autologous fat injection. During this repetitive stimulation, the tissues become grossly expanded, developing macroscopic swelling that regresses slowly over the course of hours following the cessation of the stimulus. The system sets various mechanisms in motion, including scar release, mechanical stimulation, edema, ischemia, and inflammation, which provide an environment conducive for cell proliferation and angiogenesis. In order to maintain the graft construct in its expansive state, all patients are encouraged postoperatively to use the Kiwi three times daily for one minute per session over the course of three days. The handling of this system is simple for both the patients and the surgeon. Satisfactory clinical outcomes have been achieved without significant complications. PMID- 27689055 TI - Three-Directional Reconstruction of a Massive Perineal Defect after Wide Local Excision of Extramammary Paget's Disease. AB - Extramammary Paget's disease (EMPD) is a rare, slow-growing intraepithelial malignancy that mainly involves the genital region, including the vulva, penis, scrotum, perianal, and periurethral areas. Although several treatment options exist, wide local excision with a safe margin is considered the treatment of choice. After resection of the lesion, it is often challenging to reconstruct the defect because defects in the perineal region require adequate volume for protection and are susceptible to infections, which is a particularly significant risk for large defects. We report a case of perivulvar EMPD that was reconstructed with three-directional local flaps after wide excision of the tumor. We covered the defect sequentially using the following 3 flaps: a gracilis myocutaneous flap from the left thigh, a bipedicled V-Y advancement flap from the lower abdomen, and an internal pudendal artery perforator-based island flap from the right buttock. To the best of our knowledge, this report is the first to describe a three-directional approach to extensive perivulvar reconstruction. PMID- 27689057 TI - A Novel Nipple Reconstruction Technique for Maintaining Nipple Projection: The Boomerang Flap. AB - Nipple-areolar complex (NAC) reconstruction is the final step in the long journey of breast reconstruction for mastectomy patients. Successful NAC reconstruction depends on the use of appropriate surgical techniques that are simple and reliable. To date, numerous techniques have been used for nipple reconstruction, including contralateral nipple sharing and various local flaps. Recently, it has been common to utilize local flaps. However, the most common nipple reconstruction problem encountered with local flaps is the loss of nipple projection; there can be approximately 50% projection loss in reconstructed nipples over long-term follow-up. Several factors might contribute to nipple projection loss, and we tried to overcome these factors by performing nipple reconstructions using a boomerang flap technique, which is a modified C-V flap that utilizes the previous mastectomy scar to maintain long-term nipple projection.

PMID- 27689063 TI - Correlation between clinicians-assigned weights to findings and their diagnostic odd ratio; case of congestive heart failure. AB - BACKGROUND: Incorrect estimation of pretest probability and misinterpretation of test results can change post-test probability in medical decision making. The aim of this study was to evaluate how physicians assess weight of findings of congestive heart failure (CHF) and how much their estimation is correlated with findings' Diagnostic Odd Ratio (DOR). METHODS: The participants were asked to answer a questionnaire based on a scenario of a patient having dyspnea. Eighteen findings in 3 categories including: history, examination and radiographic findings were inserted along a column and a row as a matrix. The respondents had to compare each finding in the column with all other findings in the row and insert a mark in boxes below the findings of the row that had greater weight compared to the finding in the column. The weight of each finding was considered as total number of "marked boxes" in front of that finding. DOR of findings was calculated using their positive and negative likelihood ratios (LRs) based on current best evidence. Findings ranked in the order of their DOR and were compared with the ranking in the order of participants-assigned weights. We examined correlation between average weights assigned by physicians and DOR of findings. In subgroup analysis correlations between average weights assigned by physicians and DOR of history, examination and radiographic findings were examined. RESULTS: Seventy five physicians completed the questionnaire. Correlation between ranking in the order of findings' DOR and ranking in the order of clinicians-assigned weights was significant (p-value = 0.005 r = 0.64). In contrast correlations between participants-assigned weights and DOR of history, examination and radiographic findings were positive but non- significant (r = 0.181, p-value = 0.7, r = 0.343, p-value = 0.506 and r = 0.219, p-value = 0.723 respectively). CONCLUSION: Our result show that although correlation between clinicians-assigned weights and DOR of entire findings was significant, correlations between clinicians-assigned weights to the different categories of findings and their DOR were not significant. Reevaluating probabilistic reasoning by emphasis on using LRs can make pretest probability estimating and interpretation of test results more objective and would ultimate in more precise and homogenous post-test probabilities. PMID- 27689064 TI - Oxidative stress in prostate cancer patients: A systematic review of case control studies. AB - BACKGROUND: Prostate cancer (PCa) is the most common cancer in men in Western countries. In-vitro and in-vivo studies suggest that oxidative stress (OS) and antioxidants play a key role in the pathogenesis of chronic diseases including PCa, which is promoted by the production of reactive oxygen species and impaired antioxidant defense mechanisms. This study evaluates the association between OS and men with PCa. METHODS: A literature search was carried out on Medline, PubMed, and ScienceDirect databases, as well as manual searches from inception up to August 2015 using the keywords "Oxidative stress" or "Reactive oxygen species" or "Lipid peroxidation" AND "Prostate cancer." All studies including data on the measurement of OS biomarkers in PCa were included. RESULTS: Twenty-three case control studies were retrieved with sample sizes ranging from 15 to 3,613 (6,439 participants in total). Markers of OS were significantly higher in patients with PCa compared with control groups in 21 studies. Two self-controlled case studies comparing OS between PCa cells and non-PCa cells in tissue biopsies found OS to be statistically higher in PCa cancer cells. Results on markers of antioxidant capacity (superoxide dismutase, catalase, glutathione, glutathione reductase, glutathione peroxidase, uric acid, lutein, lycopene, beta carotein, vitamin A, vitamin C, vitamin E, and total antioxidants) were not completely consistent in their association with PCa. CONCLUSIONS: Upregulated OS profiles and impairment of antioxidant defense systems may play a role in men with PCa. To confirm these findings, robust clinical trials utilizing a personalized approach which monitors both OS and antioxidant markers during therapy are warranted. PMID- 27689065 TI - Asia prostate cancer study (A-CaP Study) launch symposium. AB - The Asian Prostate Cancer (A-CaP) Study is an Asia-wide initiative that has been developed over the course of 2 years. The A-CaP Study is scheduled to begin in 2016, when each participating country or region will begin registration of newly diagnosed prostate cancer patients and conduct prognosis investigations. From the data gathered, common research themes will be identified, such as comparisons among Asian countries of background factors in newly diagnosed prostate cancer patients. This is the first Asia-wide study of prostate cancer and has developed from single country research efforts in this field, including in Japan and Korea. The inaugural Board Meeting of A-CaP was held on December 11, 2015 at the Research Center for Advanced Science and Technology, The University of Tokyo, attended by representatives of all participating countries and regions, who signed a memorandum of understanding concerning registration for A-CaP. Following the Board Meeting an A-CaP Launch Symposium was held. The symposium was attended by representatives of countries and regions participating in A-CaP, who gave presentations. Presentations and a keynote address were also delivered by representatives of the University of California San Francisco, USA, and the Peter MacCallum Cancer Centre, Australia, who provided insight and experience on similar databases compiled in their respective countries. PMID- 27689067 TI - Cytoreductive surgery for men with metastatic prostate cancer. AB - BACKGROUND: Cytoreductive surgery for metastatic prostate cancer is an emerging area of interest with a potential upside that includes local control, delayed initiation of hormone therapy, and possibly improved cancer specific survival. In order for radical prostatectomy to be an effective treatment option for men in this group, the benefits must outweigh the surgical morbidity. The aim of this study was to present a case series and assess the literature feasibility of cytoreductive surgery for men with metastatic prostate cancer. METHODS: A retrospective review of clinical notes was performed to identify men with metastatic prostate cancer who underwent cytoreductive surgery between 2012 and 2014 for a group of urologists at a single institution in Melbourne. Each patient was evaluated with regard to preoperative prostate-specific antigen, grade, stage, adjuvant therapy, and surgical outcomes. RESULTS: Six cases were identified. This included 1 pelvic exenteration and 5 robot-assisted radical prostatectomies. The men who underwent RARP had uncomplicated recoveries, regained continence within 3 months and remained pad-free at follow up. All patients proceeded to additional treatment of sites of metastatic disease with a variable PSA response, however, 3 of 6 men required recommencement of ADT for biochemical progression at follow up. CONCLUSIONS: This data supports recent findings demonstrating that radical prostatectomy for metastatic prostate cancer is feasible. Further studies are needed to explore the role of cytoreductive surgery with regards to the potential oncological benefit. PMID- 27689066 TI - Prostate-based biofluids for the detection of prostate cancer: A comparative study of the diagnostic performance of cell-sourced RNA biomarkers. AB - BACKGROUND: Prostate cancer (PCa) diagnosis requires improvement with the aid of more accurate biomarkers. Postejaculate urethral washings (PEUW) could be a physiological equivalent to urine obtained following rectal prostatic massage, the current basis for the prostate cancer antigen 3 (PCA3) test. The aim of this study was to investigate if PEUW contained prostate-based material, evidenced by the presence of prostate specific antigen (PSA), and to evaluate the diagnostic performance of PEUW-based biomarkers. METHODS: Male patients referred for elevated serum PSA or abnormal digital rectal examination provided ejaculate and PEUW samples. PSA, PCA3, and beta2-microglobulin (beta2M) were quantified in ejaculate and PEUW and compared with absolute and clinically significant (according to D'Amico criteria) PCa presence, as determined by biopsies. Diagnostic performance was determined and compared with serum PSA using receiver operating characteristic analysis. RESULTS: From 83 patients who provided PEUW samples, paired analysis with ejaculate samples was possible for 38 patients, while analysis in an unpaired, extended cohort was possible for 62 patients. PSA and PCA3 were detected in PEUW, normalized to beta2M, and PCA3:PSA was calculated. In predicting absolute PCa status, PCA3:beta2M in ejaculate [area under the curve (AUC) 0.717] and PEUW (AUC 0.569) were insignificantly better than PCA3:PSA (AUC 0.668 and 0.431, respectively) and comparable with serum PSA (AUC 0.617) with similar trends observed for the extended cohort. When considering clinically significant PCa presence, serum PSA in the comparison (AUC 0.640) and extended cohorts (AUC 0.665) was comparable with PCA3: beta2M (AUC 0.667) and PCA3:PSA (AUC 0.605) in ejaculate, with lower estimates for PEUW in the comparison (PCA3: beta2M AUC 0.496; PCA3:PSA AUC 0.342) and extended (PCA3: beta2M AUC 0.497; PCA3:PSA AUC 0.469) cohorts. The statistical analysis was limited by sample size. CONCLUSION: PEUW contains prostatic material, but has limited diagnostic accuracy when considering cell-derived DNA analysis. PCA3 based markers in ejaculate are comparable to serum PSA and digital rectal examination-urine markers. PMID- 27689068 TI - Incidental prostate cancer diagnosed at radical cystoprostatectomy for bladder cancer: disease-specific outcomes and survival. AB - BACKGROUND: The current standard of care for men with muscle-invasive bladder cancer is radical cystoprostatectomy (RCP). One-third of RCP specimens demonstrate incidental prostate cancer, primarily reported in small series with limited follow-up. The aim of this study is to report mature outcomes, including patterns of failure and disease-specific recurrence rates, and survival, for a large cohort of men with incidental prostate cancer at RCP performed at a tertiary referral center. METHODS: This retrospective study describes cancer control and survival rates for men who underwent RCP for bladder cancer and were found incidentally to have prostate cancer. Analysis of patient-, tumor-, and treatment-specific factors were analyzed for association with disease control and survival endpoints. RESULTS: Between 2002 and 2010, 94 patients with incidental discovery of prostate cancer postRCP were identified for inclusion in this study. Forty-five patients (45%) underwent RCP for recurrent (rather than initial presentation of) bladder carcinoma. At a median follow-up of 40.3 months (71.2 months for survivors; range, 8.9-155.5 months), 42 patients were alive without recurrence and 52 patients had died (25 associated with disease). The estimated 5 year bladder cancer disease-free, urinary tract malignancy disease-free, and prostate specific antigen (PSA) relapse-free survivals were 76% [95% confidence interval (CI), 65-84%], 64% (52-74%), and 97% (79-100%), respectively. The estimated 5-year urinary tract malignancy-specific and overall survivals were 61% (49-71%) and 52% (41-62%), respectively. Univariate analysis demonstrated associations between pathologic T/N-stage and nodal ratio with bladder cancer disease-free, urinary tract malignancy disease-specific, and overall survivals, with patient age at diagnosis as an additional adverse factor associated with overall survival. Multivariate analysis confirmed pN-stage and age as independently associated with worse survival. CONCLUSION: For men undergoing RCP for bladder cancer, the present study suggests that incidentally discovered prostate cancers, irrespective of pathologic stage, Gleason score, or clinical significance, do not impact 5-year disease control or survival outcomes. PMID- 27689069 TI - Optimizing prophylactic antibiotic regimen in patients admitted for transrectal ultrasound-guided prostate biopsies: A prospective randomized study. AB - BACKGROUND: Transrectal ultrasound-guided prostate biopsies (TRUSBx), in spite of being one of the most frequently performed urological office procedures, are associated with a spectrum of complications, most significantly including infection. The aim of the study is to evaluate the prevalence of fluoroquinolone resistant bacteria in rectal swabs from our local population prior to TRUSBx and to identify risk factors among a patient population harboring fluoroquinolone resistant organisms. METHODS: We prospectively included 541 men who were submitted for TRUSBx in our center from March 2011 to June 2015. The indications for TRUSBx were an elevated prostate-specific antigen level and/or abnormal digital rectal exam. All patients were randomly divided into two groups: Group 1 (n = 279 cases) who received standard empirical prophylactic antibiotics and Group 2 who received targeted prophylaxis based on a rectal swab culture and susceptibility result. Differences in risk factors between quinolone-resistant and nonresistant patients were compared. Univariate and multivariate analyses were performed to identify independent potential risk factors associated with fluoroquinolone-resistant rectal flora. RESULTS: Sixteen out of 271 men developed infectious complications after TRUSBx in the group receiving standard empirical prophylaxis (5.7%). No men in the group who received targeted prophylactic antibiotic guided by rectal swab developed infectious complications. Among the 262 patients who underwent prebiopsy rectal swab cultures, 76 men (29%) displayed fluoroquinolone-resistant rectal flora (29%). In the multivariate analysis, a history of antibiotic exposure before prostate biopsy was the only independent factor associated with an increased risk of fluoroquinolone resistance. CONCLUSION: Determining the prevalence of fluoroquinolone resistance in rectal flora has important implications in the selection of targeted prophylactic antibiotic regimens. Antimicrobial profiles guided by rectal swabs may prove useful to optimize prophylaxis prior to TRUSBx; this strategy is effective at reducing the rates of infectious complications, including sepsis, especially in men at higher risk of infectious complications. PMID- 27689070 TI - Incidence and mortality of prostate cancer and their relationship with the Human Development Index worldwide. AB - BACKGROUND: The aim of this study was to evaluate the incidence and mortality of prostate cancer and their relationship with the Human Development Index (HDI) and its components in Asia in 2012. METHODS: This study was an ecological study conducted based on the GLOBOCAN project of the World Health Organization. The correlation between standardized incidence rate (SIR) and standardized mortality rate (SMR) of prostate cancer with HDI and its components was assessed using SPSS Inc Version 18.0 (Chicago). RESULTS: There were 1,094,916 incident cases of prostate cancer and 307,481 deaths recorded in 2012 worldwide. SIR and SMR due to HDI were 72 and 9.7 in very high human development regions, 37.5 and 12.9 in high human development regions, 7 and 3.7 in medium human development regions, and 14.9 and 12.1 in low human development regions per 100,000 people, respectively. A positive correlation of 0.475 was seen between SIR of prostate cancer and HDI (P <= 0.001). Also, a negative correlation of 0.160 was seen between SMR of prostate cancer and HDI (P = 0.032). CONCLUSION: The incidence of prostate cancer is high in countries with higher development. A positive correlation was observed between the SIR of prostate cancer and the HDI and its components, such as life expectancy at birth, mean years of schooling, and the gross national income per capita. In addition, there was a negative correlation between SMR and HDI. PMID- 27689071 TI - Embracing Integrative Multiomics Approaches.

PMID- 27689072 TI - The Role of Pancreatic Stone Protein in Diagnosis of Early Onset Neonatal Sepsis. AB - Introduction. Early diagnosis and treatment of neonatal sepsis may help decrease neonatal mortality. Aim of the Study. To evaluate the role of pancreatic stone protein as a marker for early onset neonatal sepsis. Methods. A hospital-based prospective study was conducted on 104 (52 uninfected and 52 infected neonates) admitted to the Neonatal Intensive Care Unit (NICU) of Zagazig University hospitals during the period from April 2014 to April 2015. All newborns were subjected to full history taking, careful neonatal assessment, blood, C-reactive protein (CRP), and serum pancreatic stone protein. Results. Serum PSP levels were significantly higher in the infected group than in the uninfected group. At a cutoff level of PSP 12.96 ng/mL, the sensitivity was 96.2%, the specificity was 88.5%, positive predictive value was 95.8%, negative predictive value was 89.3%, and area under the curve was 0.87. A significant positive correlation between CRP and PSP was found in infected group. Conclusion. The high negative predictive value of PSP (89.3%) indicates that the serum PSP level is a good marker for diagnosis of early onset neonatal sepsis and can be used to limit hospital stay and antibiotic use in neonates treated for suspected sepsis. PMID- 27689073 TI - Differences in Dry Eye Questionnaire Symptoms in Two Different Modalities of Contact Lens Wear: Silicone-Hydrogel in Daily Wear Basis and Overnight Orthokeratology. AB - Purpose. To compare the ocular surface symptoms and signs in an adult population of silicone-hydrogel (Si-Hy) contact lens (CL) wearers with another modality of CL wear, overnight orthokeratology (OK). Materials and Methods. This was a prospective and comparative study in which 31 myopic subjects were fitted with the same Si-Hy CL and 23 underwent OK treatment for 3 months. Dry eye questionnaire (DEQ) was filled in at the beginning of the study and then after 15 days, 1 month, and 3 months using each CL modality. The tear quality was evaluated with noninvasive tear break-up time. Tear production was measured with Schirmer test. Tear samples were collected with Schirmer strips being frozen to analyze the dinucleotide diadenosine tetraphosphate (Ap4A) concentration with High-Performance Liquid Chromatography (HPLC). Results. After refitting with ortho-k, a reduction in discomfort and dryness symptoms at the end of the day (p < 0.05, chi2) was observed. No significant changes were observed in Ap4A concentration in any group. Bulbar redness, limbal redness, and conjunctival staining increased significantly in the Si-Hy group (p < 0.05, Kruskal-Wallis test). Conclusion. Discomfort and dryness symptoms at the end of the day are lower in the OK CL group than in the Si-Hy CL group. PMID- 27689074 TI - Molecular Characterization of LRB7 Gene and a Water Channel Protein TIP2 in Chorispora bungeana. AB - Background. Water channel proteins, also called aquaporins, are integral membrane proteins from major intrinsic protein (MIP) family and involved in several pathways including not only water transport but also cell signaling, reproduction, and photosynthesis. The full cDNA and protein sequences of aquaporin in Chorispora bungeana Fisch. & C.A. Mey (C. bungeana) are still unknown. Results. In this study, PCR and rapid amplification of cDNA ends approaches were used to clone the full cDNA of LRB7 (GenBank accession number: EU636988) of C. bungeana. Sequence analysis indicated that it was 1235 bp, which had two introns and encoded a protein of 250 amino acids. Structure analysis revealed that the protein had two conserved NPA motifs, one of which is MIP signature sequence (SGxHxNPAVT), six membrane helix regions, and additional membrane-embedded domains. Phylogenetic analysis suggested that the protein was from TIP2 subgroup. Surprisingly, semiquantitative RT-PCR experiment and western blot analysis showed that LRB7 and TIP2 were only detectable in roots, unlike Arabidopsis and Raphanus. Connecting with our previous studies, LRB7 was supported to associate with chilling-tolerance in C. bungeana. Conclusion. This is the first time to characterize the full sequences of LRB7 gene and water channel protein in C. bungeana. Our findings contribute to understanding the water transports in plants under low temperatures.

Urate crystals-induced inflammation is a critical factor during the initiation of gouty arthritis. Berberine is well known for its anti-inflammatory activity. However, the underlying effects of berberine on monosodium urate crystals-induced inflammation remain obscure. Objectives. This study is set to explore the protective effect and mechanism of berberine on monosodium urate crystals-induced inflammation in human monocytic THP-1 cells. Methods. The mRNA levels of NLRP3 and IL-1beta were measured by Real-Time PCR, and the protein levels of NLRP3 and IL-1beta were determined by ELISA, Western blot, and immunofluorescence. Results. The NLRP3 and IL-1beta expressions were significantly increased in model group compared to that in normal group (P < 0.05). Meanwhile, there was significant reduction in the expressions of NLRP3 and IL-1beta mRNA in groups 6.25 MUM berberine and 25 MUM berberine when compared with model group (P < 0.05). Conclusions. Therefore, berberine alleviates monosodium urate crystals-induced inflammation by downregulating NLRP3 and IL 1beta expressions. The regulatory effects of berberine may be related to the inactivation of NLRP3 inflammasome. PMID- 27689076 TI - An Improved Total Variation Minimization Method Using Prior Images and Split Bregman Method in CT Reconstruction. AB - Compressive Sensing (CS) theory has great potential for reconstructing Computed Tomography (CT) images from sparse-views projection data and Total Variation- (TV ) based CT reconstruction method is very popular. However, it does not directly incorporate prior images into the reconstruction. To improve the quality of reconstructed images, this paper proposed an improved TV minimization method using prior images and Split-Bregman method in CT reconstruction, which uses prior images to obtain valuable previous information and promote the subsequent imaging process. The images obtained asynchronously were registered via Locally Linear Embedding (LLE). To validate the method, two studies were performed. Numerical simulation using an abdomen phantom has been used to demonstrate that the proposed method enables accurate reconstruction of image objects under sparse projection data. A real dataset was used to further validate the method. PMID- 27689077 TI - The Relationship between Neurocircuitry Dysfunctions and Attention Deficit Hyperactivity Disorder: A Review. AB - The prefrontal cortex is the superlative structure of brain that needs the longest developmental and maturational duration that highlights the region of attention deficit hyperactivity disorder (ADHD) in neuroimaging studies. Prefrontal cortex functions generate enormously complex and its abundant feedback neurocircuitries with subcortical structures such as striatum and thalamus established through dual neural fibers. These microneurocircuitries are called corticostriatothalamocortical (CSTC) circuits. The CSTC circuits paly an essential role in flexible behaviors. The impaired circuits increase the risk of behavioral and psychological symptoms. ADHD is an especial developmental stage of paediatric disease. It has been reported that the CSTC circuits dysfunctions in ADHD are related to homologous symptoms. This study aimed to review the symptoms of ADHD and discuss the recent advances on the effects of the disease as well as the new progress of treatments with each circuit.

PMID- 27689079 TI - Effects of Betaine Aldehyde Dehydrogenase-Transgenic Soybean on Phosphatase Activities and Rhizospheric Bacterial Community of the Saline-Alkali Soil. AB - The development of transgenic soybean has produced numerous economic benefits; however the potential impact of root exudates upon soil ecological systems and rhizospheric soil microbial diversity has also received intensive attention. In the present study, the influence of saline-alkali tolerant transgenic soybean of betaine aldehyde dehydrogenase on bacterial community structure and soil phosphatase during growth stages was investigated. The results showed that, compared with nontransgenic soybean as a control, the rhizospheric soil pH of transgenic soybean significantly decreased at the seedling stage. Compared to HN35, organic P content was 13.5% and 25.4% greater at the pod-filling stage and maturity, respectively. The acid phosphatase activity of SRTS was significantly better than HN35 by 12.74% at seedling, 14.03% at flowering, and 59.29% at podding, while alkaline phosphatase achieved maximum activity in the flowering stage and was markedly lower than HN35 by 13.25% at pod-filling. The 454 pyrosequencing technique was employed to investigate bacterial diversity, with a total of 25,499 operational taxonomic units (OTUs) obtained from the 10 samples. Notably, the effect of SRTS on microbial richness and diversity of rhizospheric soil was marked at the stage of podding and pod-filling. Proteobacteria, Acidobacteria, and Actinobacteria were the dominant phyla among all samples. Compared with HN35, the relative abundance of Proteobacteria was lower by 2.01%, 2.06%, and 5.28% at the stage of seedling, at pod-bearing, and at maturity. In genus level, the relative abundance of Gp6, Sphingomonas sp., and GP4 was significantly inhibited by SRTS at the stage of pod-bearing and pod-filling. PMID- 27689078 TI - Can Molecular Biomarkers Change the Paradigm of Pancreatic Cancer Prognosis? AB - Pancreatic ductal adenocarcinoma is one of the most lethal types of tumour, and its incidence is rising worldwide. Although survival can be improved when these tumours are detected at an early stage, this cancer is usually asymptomatic, and the disease only becomes apparent after metastasis. The only prognostic biomarker approved by the FDA to date is carbohydrate antigen 19-9 (CA19-9); however, the specificity of this biomarker has been called into question, and diagnosis is usually based on clinical parameters. Tumour size, degree of differentiation, lymph node status, presence of distant metastasis at diagnosis, protein levels of KI-67 or C-reactive protein, and mutational status of P53, KRAS, or BRCA2 are the most useful biomarkers in clinical practice. In addition to these, recent translational research has provided evidence of new biomarkers based on different molecules involved in endoplasmic reticulum stress, epithelial-to-mesenchymal transition, and noncoding RNA panels, especially microRNAs and long noncoding RNAs. These new prospects open new paths to tumour detection using minimally or noninvasive techniques such as liquid biopsies. To find sensitive and specific biomarkers to manage these patients constitutes a challenge for the research community and for public health policies. PMID- 27689082 TI - Efficacy and Safety of LASIK Combined with Accelerated Corneal Collagen Cross Linking for Myopia: Six-Month Study. AB - This was a prospective controlled clinical trial. 48 myopia patients (96 eyes) were included in this study. After LASIK, accelerated corneal collagen cross linking (ACXL) was used for myopia treatment. During 6-month follow-up, the results of LASIK-ACXL treatment were studied and compared to the LASIK-only procedure. The results showed that no statistically significant differences in UDVA, CDVA, MRSE, K mean, pachymetry, or ECD were found between the two groups at the visit after 6 months of follow-up (all P > 0.05). At 6 months postoperatively, 2 eyes lost one or more lines of visual acuity in the LASIK-ACXL group, whereas all LASIK-only treated eyes had a stable CDVA. In vivo confocal microscopy showed a decrease of keratocyte density and appearance of honeycomb like structures in the anterior residual stroma bed; the changes were similar but more pronounced following LASIK-only. None of the cases in both groups developed signs of significant keratitis, regression, or ectasia during the 6-month follow up. LASIK-ACXL can effectively correct refractive error in patients with myopia, with no significant complications during 6-month follow-up, indicating stability and morphologic change similar to those with LASIK-only treatment. PMID- 27689081 TI - Potential Effects of Corneal Cross-Linking upon the Limbus. AB - Corneal cross-linking is nowadays the most used strategy for the treatment of keratoconus and recently it has been exploited for an increasing number of different corneal pathologies, from other ectatic disorders to keratitis. The safety of this technique has been widely assessed, but clinical complications still occur. The potential effects of cross-linking treatment upon the limbus are incompletely understood; it is important therefore to investigate the effect of UV exposure upon the limbal niche, particularly as UV is known to be mutagenic to cellular DNA and the limbus is where ocular surface tumors can develop. The risk of early induction of ocular surface cancer is undoubtedly rare and has to date not been published other than in one case after cross-linking. Nevertheless it is important to further assess, understand, and reduce where possible any potential risk. The aim of this review is to summarize all the reported cases of a pathological consequence for the limbal cells, possibly induced by cross-linking UV exposure, the studies done in vitro or ex vivo, the theoretical bases for the risks due to UV exposure, and which aspects of the clinical treatment may produce higher risk, along with what possible mechanisms could be utilized to protect the limbus and the delicate stem cells present within it.

The objective of this study was to systematically evaluate the association between vitiligo and human leukocyte antigen- (HLA-) A. Methods. PubMed, Embase, Web of Science, Chinese National Knowledge Infrastructure, and reference lists were searched for relevant original articles. Results. Nineteen case-control studies comprising 3042 patients and 5614 controls were included, in which 33 HLA-A alleles were reported. Overall, three alleles (HLA-A*02, A*33, and Aw*31) were significantly associated with increased risk of vitiligo, two (HLA A*09 and Aw*19) were associated with decreased risk, and the remaining 28 were unassociated. Twelve alleles, seven alleles, and 19 alleles were common to three ethnicities, both types of vitiligo, and both typing methods, respectively. In the subgroup analysis by ethnicity and typing methods, the association of six alleles and five alleles was inconsistent in three populations and both typing methods, respectively. In the subgroup analysis by clinical type, the association of all seven alleles was consistent in both types of vitiligo. Conclusion. The meta-analysis suggests that HLA-A*02, A*33, and Aw*31 are associated with increased risk of vitiligo, while HLA-A*09 and Aw*19 are associated with decreased risk of vitiligo. The association of some alleles varies in terms of ethnicity and typing methods. PMID- 27689084 TI - Analyzing the miRNA-Gene Networks to Mine the Important miRNAs under Skin of Human and Mouse. AB - Genetic networks provide new mechanistic insights into the diversity of species morphology. In this study, we have integrated the MGI, GEO, and miRNA database to analyze the genetic regulatory networks under morphology difference of integument of humans and mice. We found that the gene expression network in the skin is highly divergent between human and mouse. The GO term of secretion was highly enriched, and this category was specific in human compared to mouse. These secretion genes might be involved in eccrine system evolution in human. In addition, total 62,637 miRNA binding target sites were predicted in human integument genes (IGs), while 26,280 miRNA binding target sites were predicted in mouse IGs. The interactions between miRNAs and IGs in human are more complex than those in mouse. Furthermore, hsa-miR-548, mmu-miR-466, and mmu-miR-467 have an enormous number of targets on IGs, which both have the role of inhibition of host immunity response. The pattern of distribution on the chromosome of these three miRNAs families is very different. The interaction of miRNA/IGs has added the new dimension in traditional gene regulation networks of skin. Our results are generating new insights into the gene networks basis of skin difference between human and mouse. PMID- 27689086 TI - The Effect of Advanced Motherhood on Newborn Offspring's Hippocampal Neural Stem Cell Proliferation. AB - Objective. To investigate the effect of advanced motherhood on rat hippocampal neural stem cell proliferation. Methods. Female parents were subdivided into control and old mother group by age, and neural stem cells were cultured from hippocampal tissues for 24 h newborn offspring. The diameter and numbers of neurospheres were examined by microscopy, and differences in proliferation were examined by EdU immunofluorescence, CCK-8 assay, and cell cycle analysis. Results. The number of neurospheres in the old mother group after culture was lower than the control group. Additionally, neurospheres' diameter was smaller than that of the control group (P < 0.05). The EdU positive rate of the old mother group was lower than that of the control group (P < 0.05). CCK-8 assay results showed that the absorbance values for the old mother group were lower than that of the control group at 48 h and 72 h (P < 0.05). The proportions of cells in the S and G2/M phases of the cell cycle for the older mother group were less than that found for the control group (P < 0.05). Conclusion. The proliferation rates of hippocampal NSCs seen in the older mother group were lower than that seen in the control group. PMID- 27689087 TI - rLj-RGD3, a Novel Three-RGD-Motif-Containing Recombinant Protein from Lampetra japonica, Protects PC12 Cells from Injury Induced by Oxygen-Glucose Deprivation and Reperfusion. AB - rLj-RGD3 is a 14.5 kDa recombinant protein with 3 RGD (Arg-Gly-Asp) motifs from the salivary gland secretions of Lampetra japonica, which is a histidine-rich and arginine-rich protein. Previous reports indicated that rLj-RGD3 has typical functions of RGD-toxin protein, such as platelet aggregation suppression tumour metastasis and angiogenesis inhibition. Because histidine and arginine have cerebral ischemia-reperfusion and neuroprotective functions, we investigated whether rLj-RGD3 has such activities and studied the mechanism. The effects of rLj-RGD3 on neuroprotection and antiapoptosis were determined. The expression level of focal adhesion kinase (FAK), p-FAK, Caspase-3, and Bcl-2 after oxygen glucose deprivation and reperfusion (OGD-R) was examined. The viability of PC12 cells incubated with rLj-RGD3 at high concentrations (16 MUmol/L) increased significantly due to its ability to protect the cells from apoptosis after OGD-R induced injury. Furthermore, rLj-RGD3 attenuated the damage due to OGD-R. Most of the PC12 cells were apoptotic after OGD-R. In contrast, the number of apoptotic PC12 cells was significantly decreased in the group treated with a high-dose of rLj-RGD3. In addition, rLj-RGD3 activated FAK and p-FAK protein. rLj-RGD3 inhibited Caspase-3 and upregulated Bcl-2 protein expression in PC12 cells after OGD-R. The study provides the first evidence for neuroprotective effects of rLj RGD3 in ischemic injury that may be partly mediated through inhibition of Caspase 3 and upregulation of Bcl-2, FAK, and p-FAK protein expression.

AB - With the exponential growth in the capacity of information generated and the emerging need for data to be stored for prolonged period of time, there emerges a need for a storage medium with high capacity, high storage density, and possibility to withstand extreme environmental conditions. DNA emerges as the prospective medium for data storage with its striking features. Diverse encoding models for reading and writing data onto DNA, codes for encrypting data which addresses issues of error generation, and approaches for developing codons and storage styles have been developed over the recent past. DNA has been identified as a potential medium for secret writing, which achieves the way towards DNA cryptography and stenography. DNA utilized as an organic memory device along with big data storage and analytics in DNA has paved the way towards DNA computing for solving computational problems. This paper critically analyzes the various methods used for encoding and encrypting data onto DNA while identifying the advantages and capability of every scheme to overcome the drawbacks identified priorly. Cryptography and stenography techniques have been analyzed in a critical approach while identifying the limitations of each method. This paper also identifies the advantages and limitations of DNA as a memory device and memory applications. PMID- 27689090 TI - Robust Individual-Cell/Object Tracking via PCANet Deep Network in Biomedicine and Computer Vision. AB - Tracking individual-cell/object over time is important in understanding drug treatment effects on cancer cells and video surveillance. A fundamental problem of individual-cell/object tracking is to simultaneously address the cell/object appearance variations caused by intrinsic and extrinsic factors. In this paper, inspired by the architecture of deep learning, we propose a robust feature learning method for constructing discriminative appearance models without large scale pretraining. Specifically, in the initial frames, an unsupervised method is firstly used to learn the abstract feature of a target by exploiting both classic principal component analysis (PCA) algorithms with recent deep learning representation architectures. We use learned PCA eigenvectors as filters and develop a novel algorithm to represent a target by composing of a PCA-based filter bank layer, a nonlinear layer, and a patch-based pooling layer, respectively. Then, based on the feature representation, a neural network with one hidden layer is trained in a supervised mode to construct a discriminative appearance model. Finally, to alleviate the tracker drifting problem, a sample update scheme is carefully designed to keep track of the most representative and diverse samples during tracking. We test the proposed tracking method on two standard individual cell/object tracking benchmarks to show our tracker's state of-the-art performance. PMID- 27689091 TI - Anaerobic Codigestion of Municipal Wastewater Treatment Plant Sludge with Food Waste: A Case Study. AB - The aim of this study was to assess the effects of the codigestion of food manufacturing and processing wastes (FW) with sewage sludge (SS), that is, municipal wastewater treatment plant primary sludge and waste activated sludge. Bench scale mesophilic anaerobic reactors were fed intermittently with varying ratio of SS and FW and operated at a hydraulic retention time of 20 days and organic loading of 2.0 kg TS/m3.d. The specific biogas production (SBP) increased by 25% to 50% with the addition of 1%-5% FW to SS which is significantly higher than the SBP from SS of 284 +/- 9.7 mLN/g VS added. Although the TS, VS, and tCOD removal slightly increased, the biogas yield and methane content improved significantly and no inhibitory effects were observed as indicated by the stable pH throughout the experiment. Metal screening of the digestate suggested the biosolids meet the guidelines for use as a soil conditioner. Batch biochemical methane potential tests at different ratios of SS : FW were used to determine the optimum ratio using surface model analysis. The results showed that up to 47-48% FW can be codigested with SS. Overall these results confirm that codigestion has great potential in improving the methane yield of SS. PMID- 27689088 TI - Influence of Botulinumtoxin A on the Expression of Adult MyHC Isoforms in the Masticatory Muscles in Dystrophin-Deficient Mice (Mdx-Mice). AB - The most widespread animal model to investigate Duchenne muscular dystrophy is the mdx-mouse. In contrast to humans, phases of muscle degeneration are replaced by regeneration processes; hence there is only a restricted time slot for research. The aim of the study was to investigate if an intramuscular injection of BTX-A is able to break down muscle regeneration and has direct implications on the gene expression of myosin heavy chains in the corresponding treated and untreated muscles. Therefore, paralysis of the right masseter muscle was induced in adult healthy and dystrophic mice by a specific intramuscular injection of BTX A. After 21 days the mRNA expression and protein content of MyHC isoforms of the right and left masseter, temporal, and the tongue muscle were determined using quantitative RT-PCR and Western blot technique. MyHC-IIa and MyHC-I-mRNA expression significantly increased in the paralyzed masseter muscle of control mice, whereas MyHC-IIb and MyHC-IIx/d-mRNA were decreased. In dystrophic muscles no effect of BTX-A could be detected at the level of MyHC. This study suggests that BTX-A injection is a suitable method to simulate DMD-pathogenesis in healthy mice but further investigations are necessary to fully analyse the BTX-A effect and to generate sustained muscular atrophy in mdx-mice. PMID- 27689092 TI - Aberrant LncRNA Expression Profile in a Contusion Spinal Cord Injury Mouse Model. AB - Long noncoding RNAs (LncRNAs) play a crucial role in cell growth, development, and various diseases related to the central nervous system. However, LncRNA differential expression profiles in spinal cord injury are yet to be reported. In this study, we profiled the expression pattern of LncRNAs using a microarray method in a contusion spinal cord injury (SCI) mouse model. Compared with a spinal cord without injury, few changes in LncRNA expression levels were noted 1 day after injury. The differential changes in LncRNA expression peaked 1 week after SCI and subsequently declined until 3 weeks after injury. Quantitative real time polymerase chain reaction (qRT-PCR) was used to validate the reliability of the microarray, demonstrating that the results were reliable. Gene ontology (GO) analysis indicated that differentially expressed mRNAs were involved in transport, cell adhesion, ion transport, and metabolic processes, among others. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis showed that the neuroactive ligand-receptor interaction, the PI3K-Akt signaling pathway, and focal adhesions were potentially implicated in SCI pathology. We constructed a dynamic LncRNA-mRNA network containing 264 LncRNAs and 949 mRNAs to elucidate the interactions between the LncRNAs and mRNAs. Overall, the results from this study indicate for the first time that LncRNAs are differentially expressed in a contusion SCI mouse model. PMID- 27689093 TI - Angiogenic Effects of Collagen/Mesoporous Nanoparticle Composite Scaffold Delivering VEGF165. AB - Vascularization is a key issue for the success of tissue engineering to repair damaged tissue. In this study, we report a composite scaffold delivering angiogenic factor for this purpose. Vascular endothelial growth factor (VEGF) was loaded on mesoporous silica nanoparticle (MSN), which was then incorporated within a type I collagen sponge, to produce collagen/MSN/VEGF (CMV) scaffold. The CMV composite scaffold could release VEGF sustainably over the test period of 28 days. The release of VEGF improved the cell proliferation. Moreover, the in vivo angiogenesis of the scaffold, as studied by the chick chorioallantoic membrane (CAM) model, showed that the VEGF-releasing scaffold induced significantly increased number of blood vessel complexes when compared with VEGF-free scaffold. The composite scaffold showed good biocompatibility, as examined in rat subcutaneous tissue. These results demonstrate that the CMV scaffold with VEGF releasing capacity can be potentially used to stimulate angiogenesis and tissue repair. PMID- 27689094 TI - Preparation of Thermosensitive Gel for Controlled Release of Levofloxacin and Their Application in the Treatment of Multidrug-Resistant Bacteria. AB - Levofloxacin is a synthetic broad-spectrum antibacterial agent for oral or intravenous administration. Chemically, levofloxacin is the levorotatory isomer (L-isomer) of racemate ofloxacin, a fluoroquinolone antibacterial agent. Quinolone derivatives rapidly and specifically inhibit the synthesis of bacterial DNA. Levofloxacin has in vitro activity against a broad range of aerobic and anaerobic Gram-positive and Gram-negative bacteria. However, formulation of combined poloxamers thermoregulated (as Pluronic(r) F127) and levofloxacin for use in multiresistant bacterial treatment were poorly described in the current literature. Thus, the aim of the present work is to characterize poloxamers for levofloxacin controlled release and their use in the treatment of multidrug bacterial resistance. Micelles were produced in colloidal dispersions, with a diameter between 5 and 100 nm, which form spontaneously from amphiphilic molecules under certain conditions as concentration and temperature. Encapsulation of levofloxacin into nanospheres showed efficiency and enhancement of antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae when compared with only levofloxacin. Furthermore, all formulations were not cytotoxic for NIH/3T3 cell lineage. In conclusion, poloxamers combined with levofloxacin have shown promising results, better than alone, decreasing the minimal inhibitory concentration of the studied bacterial multiresistance strains. In the future, this new formulation will be used after being tested in animal models in patients with resistant bacterial strains. PMID- 27689096 TI - Development and Validation of a Simple Risk Score for Undiagnosed Type 2 Diabetes in a Resource-Constrained Setting. AB - Objective. To develop and validate a risk score for detecting cases of undiagnosed diabetes in a resource-constrained country. Methods. Two population based studies in Peruvian population aged >=35 years were used in the analysis: the ENINBSC survey (n = 2,472) and the CRONICAS Cohort Study (n = 2,945). Fasting plasma glucose >=7.0 mmol/L was used to diagnose diabetes in both studies. Coefficients for risk score were derived from the ENINBSC data and then the performance was validated using both baseline and follow-up data of the CRONICAS Cohort Study. Results. The prevalence of undiagnosed diabetes was 2.0% in the ENINBSC survey and 2.9% in the CRONICAS Cohort Study. Predictors of undiagnosed diabetes were age, diabetes in first-degree relatives, and waist circumference. Score values ranged from 0 to 4, with an optimal cutoff >=2 and had a moderate performance when applied in the CRONICAS baseline data (AUC = 0.68; 95% CI: 0.62 0.73; sensitivity 70%; specificity 59%). When predicting incident cases, the AUC was 0.66 (95% CI: 0.61-0.71), with a sensitivity of 69% and specificity of 59%. Conclusions. A simple nonblood based risk score based on age, diabetes in first degree relatives, and waist circumference can be used as a simple screening tool for undiagnosed and incident cases of diabetes in Peru.

AB - Interleukin-10, an important regulator of both the innate and adaptive immune systems, is a multifunctional major cytokine. Though it is one of the major cytokines, IL-10 from the Indian major carp, Labeo rohita, has not yet been characterized. In the present study, we report large scale production and purification of biologically active recombinant IL-10 of L. rohita (rLrIL-10) using a heterologous expression system and its biophysical and functional characterization. High yield (~70 mg/L) of soluble rLrIL-10 was obtained at shake flask level. The rLrIL-10 was found to exist as a dimer. Far-UV CD spectroscopy showed presence of predominantly alpha helices. The tertiary structure of the purified rLrIL-10 was verified by fluorescence spectroscopy. Two-dimensional gel analysis revealed the presence of six isoforms of the rLrIL-10. The rLrIL-10 was biologically active and its administration significantly reduced serum proinflammatory cytokines, namely, interleukin 1beta, TNFalpha, and IL-8, and augmented the NKEF transcript levels in spleen of L. rohita. Anti-inflammatory role of the rLrIL-10 was further established by inhibition of phagocytosis using NBT reduction assay in vitro. The data indicate that the dimeric alpha helical structure and function of IL-10 of L. rohita as a key regulator of anti inflammatory response have remained conserved during evolution.

AB - Rift Valley Fever (RVF) is an infectious illness with serious clinical manifestations and health consequences in humans as well as a wide range of domestic ruminants. This review provides significant information about the prevention options of RVF along with the safety-efficacy profile of commercial vaccines and some of RVF vaccination strategies. Information presented in this paper was obtained through a systematic investigation of published data about RVF vaccines. Like other viral diseases, the prevention of RVF relies heavily on immunization of susceptible herds with safe and cost-effective vaccine that is able to confer long-term protective immunity. Several strains of RVF vaccines have been developed and are available in commercial production including Formalin Inactivated vaccine, live attenuated Smithburn vaccine, and the most recent Clone13. Although Formalin-Inactivated vaccine and live attenuated Smithburn vaccine are immunogenic and widely used in prevention programs, they proved to be accompanied by significant concerns. Despite Clone13 vaccine being suggested as safe in pregnant ewes and as highly immunogenic along with its potential for differentiating infected from vaccinated animals (DIVA), a recent study raised concerns about the safety of the vaccine during the first trimester of gestation. Accordingly, RVF vaccines that are currently available in the market to a significant extent do not fulfill the requirements of safety, potency, and DIVA. These adverse effects stressed the need for developing new vaccines with an excellent safety profile to bridge the gap in safety and immunity. Bringing RVF vaccine candidates to local markets besides the absence of validated serological test for DIVA remain the major challenges of RVF control. PMID- 27689095 TI - Key Challenges and Opportunities Associated with the Use of In Vitro Models to Detect Human DILI: Integrated Risk Assessment and Mitigation Plans. AB - Drug-induced liver injury (DILI) is a major cause of late-stage clinical drug attrition, market withdrawal, black-box warnings, and acute liver failure. Consequently, it has been an area of focus for toxicologists and clinicians for several decades. In spite of considerable efforts, limited improvements in DILI prediction have been made and efforts to improve existing preclinical models or develop new test systems remain a high priority. While prediction of intrinsic DILI has improved, identifying compounds with a risk for idiosyncratic DILI (iDILI) remains extremely challenging because of the lack of a clear mechanistic understanding and the multifactorial pathogenesis of idiosyncratic drug reactions. Well-defined clinical diagnostic criteria and risk factors are also missing. This paper summarizes key data interpretation challenges, practical considerations, model limitations, and the need for an integrated risk assessment. As demonstrated through selected initiatives to address other types of toxicities, opportunities exist however for improvement, especially through better concerted efforts at harmonization of current, emerging and novel in vitro systems or through the establishment of strategies for implementation of preclinical DILI models across the pharmaceutical industry. Perspectives on the incorporation of newer technologies and the value of precompetitive consortia to identify useful practices are also discussed.

AB - Multidrug-resistant enterococcal nosocomial invasive infections are a rising concern faced by the medical community. Not many options are available to treat these highly virulent organisms. Risk factors for developing these highly resistant organisms include prolonged hospital stay, previous antibiotic use, and immunosuppression. In this article, we report a case of daptomycin-resistant enterococcal native infective endocarditis treated with off-label use of quinupristin-dalfopristin. PMID- 27689101 TI - Expression mediated by three partial sequences of the human tyrosine hydroxylase promoter in vivo. AB - The use of viral vectors to transfect postmitotic neurons has provided an important research tool, and it offers promise for treatment of neurologic disease. The utility of vectors is enhanced by the use of selective promoters that permit control of the cellular site of expression. One potential clinical application is in the neurorestorative treatment of Parkinson's disease by the induction of new axon growth. However, many of the genes with an ability to restore axons have oncogenic potential. Therefore, clinical safety would be enhanced by restriction of expression to neurons affected by the disease, particularly dopamine neurons. To achieve this goal we have evaluated in vivo three partial sequences of the promoter for human tyrosine hydroxylase, the rate limiting enzyme in catecholamine synthesis. All sequences induced expression in dopamine neurons. None of them induced expression in glia or in nondopaminergic neurons in striatum or cortex. We conclude that these sequences have potential use for targeting dopamine neurons in research and clinical applications. PMID- 27689102 TI - Bronchopulmonary Dysplasia in Preterm Infants Born at Less Than 32 Weeks Gestation. AB - OBJECTIVES: Bronchopulmonary dysplasia (BPD) is a chronic pulmonary disorder affecting preterm infants. We studied the factors and echocardiographic evidence of early pulmonary hypertension (PH) associated with moderate or severe BPD. METHODS: We retrospectively reviewed preterm infants who were born at <32 weeks gestation and admitted to the neonatal intensive care unit at the Children's Hospital of Zhejiang University School of Medicine between July 2013 and July 2015. RESULTS: Forty-two preterm infants were enrolled in the study. All the patients received oxygen treatment for a mean of 62.5 +/- 28.0 days. The grades of BPD were classified as follows: severe, 35.7%; moderate, 40.5%; and mild, 23.8%. The time of ventilator and oxygen supplementation was longer in infants who developed PH. Severe BPD was related to PH at 28 days. CONCLUSIONS: These findings support the notion that early pulmonary vascular disease and long-term infection in preterm infants contributes to increased susceptibility for severe BPD. PMID- 27689099 TI - Rotavirus Recombinant VP6 Nanotubes Act as an Immunomodulator and Delivery Vehicle for Norovirus Virus-Like Particles. AB - We have recently shown that tubular form of rotavirus (RV) recombinant VP6 protein has an in vivo adjuvant effect on the immunogenicity of norovirus (NoV) virus-like particle (VLP) vaccine candidate. In here, we investigated in vitro effect of VP6 on antigen presenting cell (APC) activation and maturation and whether VP6 facilitates NoV VLP uptake by these APCs. Mouse macrophage cell line RAW 264.7 and dendritic cell line JAWSII were used as model APCs. Internalization of VP6, cell surface expression of CD40, CD80, CD86, and major histocompatibility class II molecules, and cytokine and chemokine production were analyzed. VP6 nanotubes were efficiently internalized by APCs. VP6 upregulated the expression of cell surface activation and maturation molecules and induced secretion of several proinflammatory cytokines and chemokines. The mechanism of VP6 action was shown to be partially dependent on lipid raft-mediated endocytic pathway as shown by methyl-beta-cyclodextrin inhibition on tumor necrosis factor alpha secretion. These findings add to the understanding of mechanism by which VP6 exerts its immunostimulatory and immunomodulatory actions and further support its use as a part of nonlive RV-NoV combination vaccine. PMID- 27689103 TI - Small Steps in Impacting Clinical Auscultation of Medical Students. AB - The objective of this study was to determine if a training module improves the auscultation skills of medical students at the University of Maryland School of Medicine. Second-year medical students completed pretests on 12 heart sounds followed by a 45-minute training module on clinical auscultation, with retesting immediately after the intervention and during their third-year pediatrics clerkship. The control group consisted of third-year medical students who did not have the intervention. There was a 23% improvement in the identification of heart sounds postintervention (P < .001). Diastolic and valvular murmurs were poorly identified pre- and post intervention. There was a 6% decline in accuracy of the intervention group in the following academic year. The intervention group was superior to the control group at identifying the tested heart sounds (49% vs 43%, P = .04). The accuracy of second-year medical students in identifying heart sounds improved after a brief training module. PMID- 27689104 TI - Early prediction of renal parenchymal injury with serum procalcitonin. AB - INTRODUCTION: Urinary tract infection (UTI) is one of the most common bacterial infections in children that can be associated with renal parenchymal injuries and late scars. Dimercaptosuccinic acid (DMSA) renal scan is known as golden standard for detecting acute pyelonephritis (APN) that has a lot of difficulties and limitations. OBJECTIVES: we designed this study the accuracy of one inflammatory marker, serum procalcitonin (PCT) to identify as an early predictor of renal injuries. PATIENTS AND METHODS: A prospective study was carried out in 95 patients who admitted in the hospital with the first febrile UTI. Serum PCT of all patients was measured; sensitivity, specificity, positive and negative predictive value (PPV and NPV) of this marker was analyzed compared to DMSA scan. P value <0.05 was taken as significant. RESULTS: In total, 79 females and 16 males were investigated. There are 42 cases in group 1 with normal DMSA scan and 53 patients in group two with renal parenchymal injuries in their scans. Mann Whitney test showed a meaningful relation between the two groups regarding PCT level (P<0.0001). Sensitivity, specificity, PPV and NPV of PCT reported in optimum cut off were 70%, 88.1%, 88.1% and 70%, respectively. The positive likelihood ratio (PLR) of PCT test was 5.8. CONCLUSION: In the current survey, PCT was the eligible inflammatory marker to predict renal parenchymal injuries in children with proper sensitivity, specificity, PPV and NPV that play also a pivotal role in the children aged less than 24 months, although, more studies should be undertaken to confirm. PMID- 27689105 TI - Correlation between serum leptin and bone mineral density in hemodialysis patients. AB - INTRODUCTION: For diagnosing of specific types of bone lesions in hemodialysis (HD) patients, it is necessary to conduct a bone biopsy as the gold standard method. However, it is an invasive procedure. While different markers have been suggested as alternative methods, none of them has been selected. The frequency of hip fractures is 80 fold in HD patients who have two-fold mortality as compared with general population. OBJECTIVES: Recently, serum leptin has been suggested as a bone density marker. This study tries to confirm this proposal. PATIENTS AND METHODS: In this study about 104 HD patients (53.8% male and 46.2% female) were enrolled. The average age was 38.28+/-7.89 years. Serum leptin, bone alkaline phosphatase, intact parathyroid hormone (iPTH), 25(OH)D, calcium, phosphorus and bone mineral density (BMD) (at the femoral neck and lumbar spine, as measured by dual-energy x-ray absorptiometry [DXA]) were assessed. RESULTS: Analysis by polynomial regression revealed no correlation between BMD Z-score at two points and serum leptin level. According to the thresholds of 25 ng/mL and 18 24 ng/mL in some studies, we detected 25 ng/mL as the threshold in our patients. Under this threshold, the leptin effect on bone mass was negative, and above the threshold of 25 ng/mL, we found leptin had positive effect on bone mass. CONCLUSION: In this investigation, we found, leptin has a bimodal effect on bone mass. Cortical bones assessment may be a better option for assessment. PMID- 27689106 TI - The evaluation of relationship between blood pressure and dialysate Na concentration in chronic hemodialysis patients. AB - INTRODUCTION: Hypertension is one of the traditional risk factors of cardiovascular disease (CVD). Extra cellular volume expansion and Na retention remain the main cause of hypertension. OBJECTIVES: The aim of this study was to investigate the relation between concentration of Na dialysate and blood pressure (BP) in chronic hemodialysis (HD) patient. PATIENTS AND METHODS: This cross sectional study was performed on 266 adult patients undergoing HD for at least three months. Pre-HD systolic BP (SBP) and post-HD SBP during 4 weeks were measured in relation to Na dialysate concentration. The other main factors affecting the post-dialysis BP, such as body mass index (BMI), pump speed, dialysis solution temperature, duration of dialysis and intradialysis weight gain (IDWG) were also considered. Mean of DeltaSBP (post-HD SBP - pre-HD SBP) in each patient in 12 session of HD was measured and statistically analyzed in relation to dialysate Na with SPSS 21. Backward multivariable linear regression analysis and Pearson's correlation coefficients were used to evaluate the correlation between sodium gradient and DeltaSBP. RESULTS: SBP was significantly changed before and after dialysis in relation to dialysate Na (P<0.001). The Pearson's correlation between DeltaSBP with dialysate sodium and blood flow rate (pump speed) were statistically significant(P<0.05). CONCLUSION: We found that changes in SBP before and after dialysis is significantly associated with dialysate sodium concentration. PMID- 27689107 TI - An ethnobotanical study of medicinal plants administered for the treatment of hypertension. AB - INTRODUCTION: The incidence of cardiovascular diseases (CVDs) is very high in human societies and their prevention and treatment are the most important priority in many countries. Hypertension makes an important contribution to the development of CVDs. OBJECTIVES: This study aimed to collect the ethno-medicinal knowledge of the traditional healers of Shiraz on medicinal plants used in the treatment of hypertension. MATERIALS AND METHODS: Ethno-medicinal data were collected from September 2012 to July 2013 through direct interview. Twenty-five healers were interviewed using semi-structured questionnaires and their traditional ethno-medicinal knowledge was recorded. Questionnaires were included apothecary personal information, plant local name, plant parts used, method of preparation, season of harvest and traditional use. Data collected from surveys and interviews were transferred to Microsoft Excel 2007 and analyzed. RESULTS: Analysis of data showed that, 27 medicinal plants from 22 families are used for the treatment of hypertension. The families with most antihypertensive species were Apiaceae (8%), Rosaceae (8%) and Papaveraceae (8%). The most frequently used plant parts were leaves (36%) followed by fruits (30%), aerial part (17%) and branches (7%). The most frequently used preparation method was decoction (95%). Borago officinalis (51.85%), Berberis vulgaris (51.58%) had the highest frequency of mention. CONCLUSION: The ethno-medicinal survey of medicinal plants recommended by traditional healers for the treatment of hypertension provides new areas of research on the antihypertensive effect of medicinal plants. In the case of safety and effectiveness, they can be refined and processed to produce natural drugs. PMID- 27689108 TI - Identification of medicinal plants for the treatment of kidney and urinary stones. AB - INTRODUCTION: Kidney stones are the third most common urinary tract problems after urinary tract infections and prostate pathology. Kidney stones may cause extreme pain and blockage of urine flow. They are usually treated with medications that may cause a number of side-effects. Medicinal herbs are used in different cultures as a reliable source of natural remedies. OBJECTIVES: This study aimed to determine native medicinal plants used by traditional healers of Shiraz for the treatment of kidney stones. MATERIALS AND METHODS: The ethno medicinal data were collected between July and September 2012 through face-to face interview with local herbalist. RESULTS: A total of 18 species belonging to 19 botanical families were recorded in study area. Species with the highest frequency of mentions were Alhagi maurorum (51.58%), Tribulus terrestris (51.58%), and Nigella sativa (48.14). The most frequently used plant parts were aerial parts (38%), leaf (33%) and fruits (17%). Decoction (68%) was the most frequently prescribed method of preparation. Most of the medicinal plants recommended by Shirazian herbalists have not been investigated in animal and humane models of renal stone which provides a new area of research. CONCLUSION: In the case of safety and effectiveness, they can be refined and processed to produce natural drugs. PMID- 27689109 TI - High doses of oral folate and sublingual vitamin B12 in dialysis patients with hyperhomocysteinemia. AB - INTRODUCTION: Folic acid and vitamin B12, alone or in combination have been used to reduce homocysteine (Hcy) levels in dialysis patients. OBJECTIVES: We aimed to assess the efficacy of high doses of oral folate and vitamin B12 in reducing plasma Hcy levels after a 12-week treatment. PATIENTS AND METHODS: Thirty-two dialysis patients aged 10-324 months screened for hyperhomocysteinuria. Then cases with hyperhomocysteinemia received oral folate 10 mg/day with sublingual methylcobalamin 1 mg/day for 12 weeks. In pre- and post-intervention phases plasma Hcy concentration, serum folate, and vitamin B12 levels were measured. Changes in plasma Hcy, serum folate, and vitamin B12 concentrations were analyzed by paired t tests, and P values < 0.05 were considered significant. RESULTS: Eighteen (56.2%) patients had hyperhomocysteinuria. Vitamin B12 and folate levels were normal or high in all cases. Two patients were lost due to transplant or irregular drugs consumption. Plasma Hcy levels were reduced in all, and reached normal values in 50%. A statistically significant differences between first Hcy levels with levels after intervention was found (95% CI, 5.1-8.9, P = 0.0001). CONCLUSION: Oral folate 10 mg/day in combination with sublingual vitamin B12, 1 mg/day can be considered as a favorable treatment for hyperhomocysteinemia in dialysis patients. PMID- 27689110 TI - Effect of angiotensin II type 1 receptor blockade on kidney ischemia/reperfusion; a gender-related difference. AB - BACKGROUND: Renal ischemia/reperfusion (I/R) injury may be related to activity of reninangiotensin system (RAS), which is gender-related. In this study, it was attempted to compare the effect of angiotensin II (Ang II) receptor type 1 (AT1R) blockade; losartan in I/R injury in male and female rats. MATERIALS AND METHODS: Male and female Wistar rats were assigned as sham surgery, control I/R groups treated with vehicle, and case I/R groups treated with losartan (30 mg/kg). Vehicle and losartan were given 2 hours before bilateral kidney ischemia induced by clamping renal arteries for 45 minutes followed by 24 hours of renal reperfusion. RESULTS: The I/R injury significantly increased the serum levels of blood urea nitrogen (BUN) and creatinine (Cr), and kidney tissue damage score in both genders. However, losartan decreased these values in female rats significantly (P < 0.05). This was not observed in male rats. CONCLUSION: Losartan protects the kidney from I/R injury in female but not in male rats possibly because of gender-related difference of RAS. PMID- 27689111 TI - Comparing between results and complications of doing voiding cystourethrogram in the first week following urinary tract infection and in 2-6 weeks after urinary tract infection in children referring to a teaching hospital. AB - INTRODUCTION: Urinary tract infection is the most common genitourinary disease in children so about 40% of the children with urinary tract infection suffering from reflux that caused some consequences such as pyelonephritis and kidney parenchymal injury. OBJECTIVES: This research was conducted to compare the timing of voiding cystourethrogram (VCUG) in children with urinary tract infection in first week and after the first week of urinary tract infection. PATIENTS AND METHODS: This research is a case-control study that both case and control groups include 208 children from 1 month to 12 years old with the complain of urinary tract infection. In case group, the VCUG was performed at the first week of infection and in control group, the VCUG was performed after the first week of infection. RESULTS: complication such as dysuria was observed in two-thirds of children who VCUG was performed during first week after urinary tract infection. Parents stress in case group was more than the other (P=0.015). For overall, the incidence of reflux in case and control groups was 49.5% and 50%, respectively. The mean of reflux grading in right kidney in case group was lower than control group resulting in significant differences between two groups. CONCLUSION: According to higher grade of stress in parents and complications due to VCUG at the first week of urinary tract infection, it is suggested that VCUG be conducted on selective patients in the hospital at the first week of urinary tract infection and during hospitalization. PMID- 27689112 TI - Comparison of oral Lactobacillus and Streptococcus mutans between diabetic dialysis patients with non-diabetic dialysis patients and healthy people. AB - INTRODUCTION: Diabetes is associated with higher rates of caries, on the other hand some studies have shown that renal failure can be protective against dental caries. OBJECTIVES: In this study we compared oral Lactobacillus and Streptococcus mutans between diabetic dialysis and non-diabetic dialysis patients and the normal population. PATIENTS AND METHODS: During November 2014 to January 2014, 85 people that referred to our medical care center entered the study. The sample included 30 diabetic dialysis, 28 non-diabetic dialysis patients and 27 healthy people. Oral saliva samples were obtained from their tongue and oral floor for microbiological examination. Patients' data were compared before and after dialysis. RESULTS: The amount of Lactobacillus and S. mutans did not show a significant difference between the three groups (P=0.092 and P=0.966 for S. mutans and lactobacillus, respectively). A positive and meaningful correlation was seen between fasting blood sugar (FBS) levels and the amount of S. mutans in the diabetic dialysis group (P=0.023; r=0.413). A meaningful and positive correlation was also seen between the amount of blood urea nitrogen (BUN) after dialysis and the amount of oral S. mutans in the non-diabetic dialysis group (P=0.03; r=0.403). CONCLUSION: Despite the differences in the prevalence of caries that have been reported between renal failure patients and diabetic patients, we did not find any significant difference between diabetic dialysis, non-diabetic dialysis patients and the healthy population, regarding their amount of oral cariogenic bacteria. PMID- 27689113 TI - The effects of different electrolyte composition in dialysate on QTc interval; a controlled trial. AB - INTRODUCTION: Hemodialysis (HD) has impact on the cardiovascular system by inducing changes in the characteristics of body fluids such as PH, temperature and electrolyte concentrations. In the previous studies, prolongation of the QT interval and increase of QT dispersion have been reported during HD sessions. These changes were more significant while using solutions with less potassium and higher bicarbonate during dialysis. OBJECTIVES: The aim of our study was to investigate the effects of different potassium and bicarbonate concentrations on electrocardiography (ECG) parameters and the electrochemical balance of cell membranes. PATIENTS AND METHODS: This is a double blind controlled clinical trial with crossover design. This interventional study has been conducted on 36 patients over 18 years who undergoing HD 3 times a week for at least 6 months. Twelve-lead ECG has been obtained before starting and one hour after end of each HD session. The QTc was measured and changes recorded by a cardiologist. Correlations were evaluated by univariate regression analysis. RESULTS: 54.38 years (16 to 77 years), 66.7% were male. No significant increase in QT interval has been seen while dialyzing with 2 meq/l potassium and 24 meq/l bicarbonate, 2 meq/l potassium and 28 meq/l bicarbonate and 3 meq/l potassium and 24 meq/l bicarbonate beside high calcium (2.5 meq/l) dialysate was conducted. Age, gender, serum calcium and serum bicarbonate level before HD session did not influence the mean QT intervals before and after dialysis. CONCLUSION: Concentration of potassium beside moderate dose of bicarbonate in dialysis bath had not any significant influence on QT intervals after dialysis. PMID- 27689114 TI - Correlation between cystatin C-based formulas, Schwartz formula and urinary creatinine clearance for glomerular filtration rate estimation in children with kidney disease. AB - INTRODUCTION: Assessment of glomerular filtration rate (GFR) is an important tool for monitoring renal function. OBJECTIVES: Regarding to limitations in available methods, we intended to calculate GFR by cystatin C (Cys C) based formulas and determine correlation rate of them with current methods. PATIENTS AND METHODS: We studied 72 children (38 boys and 34 girls) with renal disorders. The 24 hour urinary creatinine (Cr) clearance was the gold standard method. GFR was measured with Schwartz formula and Cys C-based formulas (Grubb, Hoek, Larsson and Simple). Then correlation rates of these formulas were determined. RESULTS: Using Pearson correlation coefficient, a significant positive correlation between all formulas and the standard method was seen (R(2) for Schwartz, Hoek, Larsson, Grubb and Simple formula was 0.639, 0.722, 0.705, 0.712, 0.722, respectively) (P<0.001). Cys C-based formulas could predict the variance of standard method results with high power. These formulas had correlation with Schwarz formula by R(2) 0.62-0.65 (intermediate correlation). Using linear regression and constant (y-intercept), it revealed that Larsson, Hoek and Grubb formulas can estimate GFR amounts with no statistical difference compared with standard method; but Schwartz and Simple formulas overestimate GFR. CONCLUSION: This study shows that Cys C-based formulas have strong relationship with 24 hour urinary Cr clearance. Hence, they can determine GFR in children with kidney injury, easier and with enough accuracy. It helps the physician to diagnosis of renal disease in early stages and improves the prognosis. PMID- 27689115 TI - The effect of lactulose supplementation on fecal microflora of patients with chronic kidney disease; a randomized clinical trial. AB - INTRODUCTION: Lactulose is a prebiotic with bifidogenic and urea reduction effects. It can improve Bifidobacteria and Lactobacilli counts in healthy humans and it may possibly have similar effects in chronic kidney disease (CKD) patients. OBJECTIVES: To investigate the effect of lactulose on fecal microflora of patients with CKD. PATIENTS AND METHODS: Thirty-two patients with stages 3 and 4 of CKD (43.8% male with mean age of 58.09+/-12.75 years) were randomly assigned to intervention (n=16) and control (n=16) groups. Patients in intervention group received 30 mm lactulose syrup three times a day for an 8-week period. Control group received placebo 30 mm three times a day. A fecal sample was obtained from all patients at the beginning and at the end of the study and Bifidobacteria and Lactobacilli was counted. RESULTS: Creatinine (Cr) significantly decreased in intervention group (3.90+/-1.43 to 3.60+/-1.44, P=0.003) and increased in control group (3.87+/-2.08 to 4.11+/-1.99, P=0.03). Although Bifidobacterial and Lactobacilli counts were similar before intervention, they were significantly higher at the end of the study in lactulose group (P=0.01 and P=0.04, respectively). Lactulose led to significant increase in fecal Bifidobacterial counts (3.61+/-0.54 to 4.90+/-0.96, P<0.001) and Lactobacilli counts (2.79+/-1.00 to 3.87+/-1.13, P<0.001), while the change in placebo group was not significant. CONCLUSION: Lactulose administration will increase Bifidobacteria and Lactobacillus counts in patients with CKD. PMID- 27689117 TI - Hypertension in children in emergency department. PMID- 27689116 TI - Splenic abscess due to fungal infection after kidney transplantation; a case report. AB - Splenic abscess is one of the rare and potentially life-threatening complications after kidney transplantation. Splenic abscess generally occurs in patients who have immunodeficiency state. It becomes more important with the increased use of immunosuppressed drugs and organ transplantation. The clinical presentation of splenic abscess is insidious, often with constitutional symptoms. Left upper quadrant tenderness is an uncommon sign. Therefore, its diagnosis is difficult and requires a high degree of clinical suspicion. We report a case under renal transplantation with recurrent fungal infection in different organs with two episodes of fungemia who died after splenectomy. PMID- 27689118 TI - Association of bone mineral density with biochemical markers of bone turnover in hemodialysis children. AB - INTRODUCTION: Although some descriptive and cross-sectional studies have been reported about bone mass in chronic kidney disease (CKD) children, only a few studies investigated markers of bone turnover and the bone mass measurements. OBJECTIVES: The aim of this study was to evaluate the association between bone mineral density (BMD) and biochemical markers of bone turnover in hemodialysis (HD) children. PATIENTS AND METHODS: The children who had received dialysis for at least the preceding 6-month were included. BMD was measured for total body, the lumbar spine and the femoral neck and the blood samples were tested to assess biochemical bone turnover markers. RESULTS: The study group was comprised of 27 patients with CKD, 9 males (33%) and 18 females (67%) with the mean+/-SD age of the subjects 14.9+/-4.5 years. Positive significant correlations of parathyroid hormone (PTH) with total body bone densitometry Z-score, lumbar spine and femoral neck Z-score(r=0.43, P=0.06; r=0.41, P=0.08 and r=0.45, P=0.05, respectively) was noted. In addition, positive significant correlations calcium and total body, lumbar spine and femoral neck Z-score (r=0.52, P=0.02; r=0.28, P=0.23 and r=0.36, P=0.12, respectively) was seen. Interestingly, a positive significant correlation between alkaline phosphatase (ALP) and lumbar spine Z-score was found (r=0.46, P=0.04), while the correlation of this parameter with total body and femoral neck Z-score was not significant (P>0.05). CONCLUSION: In our study, majority of patients with CKD had low level of BMD. In addition, lower levels of calcium (Ca), phosphorus (P), PTH and 25 (OH) vitamins D in patients with abnormal BMD Z scores were detected. PMID- 27689119 TI - Effect of selenium supplementation on lipid profile in hemodialysis patients. AB - INTRODUCTION: One of the major causes of mortality in chronic kidney disease (CKD) patients on hemodialysis is premature atherosclerosis. Selenium, a trace element involved in important enzymatic activities inside the body, has protective effects against lipid oxidation and inhibits cholesterol accumulation in blood vessels. OBJECTIVES: To determine the effect of selenium supplementation on lipid profile in hemodialysis patients. PATIENTS AND METHODS: In this double blinded randomized clinical trial which lasted for 3 months, 84 hemodialysis patients with selenium deficiency were divided into experimental group (received selenium supplementation) or control group (received placebo). Total cholesterol, low-density lipoprotein (LDL-C), high-density lipoprotein (HDL-C), blood urea nitrogen (BUN), creatinine, and selenium level were measured before and after the study. RESULTS: Mean (+/-SD) serum LDL-C level significantly increased in experimental group from 85.66 (+/-31.12) to 109.12 (+/-32.29) mg/dl (P<0.001). Likewise, in control group serum LDL-C significantly increased from 80.55 (+/ 21.13) to 97.05 (+/-28.07) mg/dl (P<0.001). However, with control of LDL-C effect before and after the study, it was revealed that LDL-C change was not statistically significant (P=0.21). Similarly, total cholesterol and triglyceride levels did not show significant changes before and after the study in any group. CONCLUSION: Selenium supplementation had no beneficial effect on lipid profile in hemodialysis patients.

AB - INTRODUCTION: Vanadium compounds are insulin like drugs which are accompanied with nephrotoxicity and hepatotoxicity as their major side effects. Aerobic exercise is well known as an approach to reduce the side effects of many drugs. OBJECTIVES: This study was designed to determine the role of aerobic exercise against vanadyl sulphate induced nephrotoxicity and hepatotoxicity in male rats. MATERIALS AND METHODS: Twenty-four male Wistar rats were randomly divided into three groups. Group I had aerobic exercise on a treadmill 5 days/week for 6 weeks. Group II received vanadyl sulphate (50 mg/kg/week; i.p.) for 6 weeks. Group III had combination of exercise and vanadyl sulphate therapy as groups 1 and 2. At the end of study, blood samples were obtained, and the animals were sacrificed for the tissues injury determination. RESULTS: Vanadyl sulphate alone increased serum levels of blood urea nitrogen (BUN), creatinine (Cr), and kidney weight (KW) and kidney tissue damage score (KTDS) (P<0.05). These observations revealed nephrotoxicity induced by vanadyl sulphate, although exercise training did not attenuate these results. In addition, vanadyl sulphate alone induced liver tissue damage score and exercise training intensified it insignificantly, while the serum levels of aspartate amino transferase and alanine amino transferase were greater in exercise alone group than others groups. CONCLUSION: Aerobic exercise could not attenuate vanadyl sulphate induced nephrotoxicity and hepatotoxicity. These findings must be considered when vanadyl sulphate is suggested as insulin like drug. PMID- 27689121 TI - Gamma-aminobutyric acid aggravates nephrotoxicity induced by cisplatin in female rats. AB - INTRODUCTION: Cisplatin (CP) is a major antineoplastic drug for treatment of solid tumors. CP-induced nephrotoxicity may be gender-related. This is while gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter in the central nervous system that has renoprotective impacts on acute renal injury. OBJECTIVES: This study was designed to investigate the protective role of GABA against CP induced nephrotoxicity in male and female rats. MATERIALS AND METHODS: Sixty Wistar male and female rats were used in eight experimental groups. Both genders received GABA (50 MUg/kg/day; i. p.) for 14 days and CP (2.5 mg/kg/day; i. p.) was added from day 8 to the end of the study, and they were compared with the control groups. At the end of the study, all animals were sacrificed and the serum levels of blood urea nitrogen (BUN), creatinine (Cr), nitrite, malondialdehyde (MDA), and magnesium (Mg) were measured. The kidney tissue damage was also determined via staining. RESULTS: CP significantly increased the serum levels of Cr and BUN, kidney weight, and kidney tissue damage score in both genders (P<0.05). GABA did not attenuate these markers in males; even these biomarkers were intensified in females. Serum level of Mg, and testis and uterus weights did not alter in the groups. However, the groups were significantly different in terms of nitrite and MDA levels. CONCLUSION: It seems that GABA did not improve nephrotoxicity induced by CP-treated rats, and it exacerbated renal damage in female rats.

AB - INTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD) is the most common childhood psychiatric disorder. This disorder is more prevalent in some chronic diseases. OBJECTIVES: To investigate ADHD in children with overactive bladder. PATIENTS AND METHODS: A number of 92 children with overactive bladder and 92 healthy children without overactive bladder (age range of both groups 5 to 12 years old) were included in this study as case and control groups, respectively. Participants were selected from children who had referred to a pediatric clinic in Arak city, Iran. ADHD types (inattentive, hyperactive-impulsive, and mixed) were diagnosed by Conner's Parent Rating Scale and Diagnostic and Statistical Manual of Mental Disorders IV-TR (DSM-IV-TR) criteria. Data were analyzed by chi square and t tests. RESULTS: In both groups, 51 children (27.7%) had ADHD. The prevalence of ADHD in the case group (33 cases, 35.9%) was significantly higher than the control group (18 cases, 19.6%) (P = 0.021). Inattentive ADHD was observed in 22 participants (23.9%) of the case group and nine participants of the control group (9.7%) (P = 0.047). Despite this significant difference, three (3.2%) and four (4.3%) children were affected by hyperactive-impulsive ADHD (P = 0.73), and eight (8.6%) and five (5.4%) children were affected by mixed ADHD (P = 0.42) in the case and control groups, respectively. CONCLUSION: ADHD bladder is significantly more common in children with overactive bladder than healthy children. The observed correlation between ADHD and overactive bladder makes psychological counseling mandatory in children with overactive bladder. PMID- 27689124 TI - Acute kidney injury in patients with paraquat intoxication; a case report and review of the literature. AB - Paraquat and diquat are classified as bipyridyl compounds not only leads to acute organ damage, but also to a variety of complications. Patients with severe paraquat-induced poisoning may succumb to multiple organ failure involving the circulatory and respiratory systems. Deliberate self-poisoning with paraquat continues to be a major public health concern in many developing countries. At present there is no specific antidote to paraquat poisoning, hence the need to more focus on prevention and in cases of poisoning aggressive decontamination to prevent further absorption. This article presented a 12-year-old male with acute kidney injury following the ingestion of paraquat in suicidal attempt and serves to explore the complications associated with paraquat poisoning and current recommended treatment. PMID- 27689123 TI - Cross-fused renal ectopia associated with vesicoureteral reflux; a case report. AB - Crossed renal ectopia is a rare urinary system anomaly which mostly is asymptomatic and is diagnosed incidentally. Urinary obstruction, infection, and neoplasia of the urinary system and nephrolithiasis are main complications of this anomaly. A 6-year-old boy admitted to the hospital with colicky abdominal pain and nausea. Abdominal examination revealed tenderness in right lower quadrant. Urine analysis and culture were normal. Kidney ultrasonography showed right kidney in pelvis cavity with no kidney tissue in left side. TC 99-DMSA scan demonstrated no radiotracer accumulation in the normal renal area. Radiotracer accumulation was seen in the pelvis area with a deviation to the left. Voiding cystoureterogram revealed right sided grade II vesicoureteral reflux. Severe urological anomalies in children may be asymptomatic or have nonspecific symptoms such as abdominal pain. PMID- 27689125 TI - Paraneoplastic proteinuria in papillary renal cell carcinoma; a case report. AB - We report a 55-year-old man presented with anemia and weakness, history of flank pain, hematuria and nephrotic syndrome. Spiral abdominopelvic computerized tomography (CT) scan showed multiloculated cystic mass (120 *100 *80 mm) in lower portion of left kidney with internal enhancing solid components and coarse peripheral calcifications. Radical nephrectomy of left kidney was done and biopsy confirmed renal cell carcinoma (RCC), papillary type, sarcomatoid foci, Fuhrman grade III. We assumed that, presence of nephrotic syndrome and paraneoplastic glomerulopathy leaded to heavy proteinuria in this case. Secondary, paraneoplastic glomerulopathy such as immunoglobulin A nephropathy and focal segmental glomerulosclerosis as a paraneoplastic syndrome of RCC have been reported previously. RCC can present with a wide range of signs and symptoms. Atypical presentations of papillary RCC such as proteinuria should be considered for patients presenting with nephrotic syndrome.

AB - Hip implants containing cobalt-chromium (CoCr) have been used for over 80 years. In patients with metal-on-metal (MoM) hip implants, it has been suggested that wear debris particles may contribute to metal sensitization in some individuals, leading to adverse reactions. This article presents data from a study in which the popliteal lymph node assay (PLNA) was used to assess immune responses in mice treated with chromium-oxide (Cr2O3) particles, metal salts (CoCl2, CrCl3, and NiCl2) or Cr2O3 particles with metal salts ("A preliminary evaluation of immune stimulation following exposure to metal particles and ions using the mouse popliteal lymph node assay" (B.E.

AB - This article refers to the paper "Assessment of table olive fermentation by functional data analysis" (Ruiz-Bellido et al., 2016) [1]. The dataset include pH, titratable acidity, yeast count and area values obtained during fermentation process (380 days) of Alorena de Malaga olives subjected to five different fermentation systems: i) control of acidified cured olives, ii) highly acidified cured olives, iii) intermediate acidified cured olives, iv) control of traditional cracked olives, and v) traditional olives cracked after 72 h of exposure to air. Many of the Tables and Figures shown in this paper were deduced after application of Functional Data Analysis to raw data using a routine executed under R software for comparison among treatments by the transformation of raw data into smooth curves and the application of a new battery of statistical tools (functional pointwise estimation of the averages and standard deviations, maximum, minimum, first and second derivatives, functional regression, and functional F and t-tests).

AB - This paper deals with the analysis of existence of traveling wave solutions (TWS) for a diffusion-degenerate (at D(0) = 0) and advection-degenerate (at h'(0) = 0) reaction-diffusion-advection (RDA) equation. Diffusion is a strictly increasing function and the reaction term generalizes the kinetic part of the Fisher-KPP equation. We consider different forms of the convection term h(u): (1) h'(u) is constant k, (2) h'(u) = ku with k > 0, and (3) it is a quite general form which guarantees the degeneracy in the advective term. In Case 1, we prove that the task can be reduced to that for the corresponding equation, where k = 0, and then previous results reported from the authors can be extended. For the other two cases, we use both analytical and numerical tools. The analysis we carried out is based on the restatement of searching TWS for the full RDA equation into a two dimensional dynamical problem. This consists of searching for the conditions on the parameter values for which there exist heteroclinic trajectories of the ordinary differential equations (ODE) system in the traveling wave coordinates. Throughout the paper we obtain the dynamics by using tools coming from qualitative theory of ODE. PMID- 27689132 TI - Insulin-Like Growth Factor-1 and Selected Insulin-Like Growth Factor Binding Protein Concentrations during an Ultramarathon Sled Dog Race. AB - The objective of this study was to investigate the effects of running a 1000-mile (1600 km) endurance sled dog race on serum insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding proteins 1 and 3 (IGFBP-1 and IGFBP-3). Serum was examined from 12 sled dogs prior to the race, at midrace (approximately 690 km), and again at the finish. IGF-1, IGFBP-1, and IGFBP-3 were assessed using radioimmunoassay or enzyme linked immune-absorbance assays. Mean prerace concentrations were significantly higher than midrace and end-race concentrations at 215.93 +/- 80.51 ng/mL, 54.29 +/- 25.45 ng/mL, and 55.53 +/- 28.25 ng/mL, respectively (P < 0.001). Mean IGFBP-1 concentrations were not different across these time periods at 24.1 +/- 15.8 ng/mL, 25.7 +/- 14.0 ng/mL, and 26.6 +/- 17.6 ng/mL, respectively. IGFBP-3 concentrations showed a modest significant decrease across time periods at 3,067 +/- 2,792 ng/mL, 2,626 +/- 2,310 ng/mL, and 2,331 +/ 2,301 ng/mL, respectively (P < 0.01). Endurance sled dogs show a precipitous drop in serum IGF-1 concentrations. These differences may be related to fuel utilization and excessive negative energy balance associated with the loss of body condition during racing. The relative stability of IGFBP-1 and IGFBP-3 suggests that IGF-1 anabolic signaling is diminished during ultramarathon racing. Further studies comparing the influence of time and duration of exercise versus negative energy balance on serum IGF-1 status are warranted to better understand exercise versus negative energy balance differences. PMID- 27689133 TI - Fuzzy Logic for Incidence Geometry. AB - The paper presents a mathematical framework for approximate geometric reasoning with extended objects in the context of Geography, in which all entities and their relationships are described by human language. These entities could be labelled by commonly used names of landmarks, water areas, and so forth. Unlike single points that are given in Cartesian coordinates, these geographic entities are extended in space and often loosely defined, but people easily perform spatial reasoning with extended geographic objects "as if they were points." Unfortunately, up to date, geographic information systems (GIS) miss the capability of geometric reasoning with extended objects. The aim of the paper is to present a mathematical apparatus for approximate geometric reasoning with extended objects that is usable in GIS. In the paper we discuss the fuzzy logic (Aliev and Tserkovny, 2011) as a reasoning system for geometry of extended objects, as well as a basis for fuzzification of the axioms of incidence geometry. The same fuzzy logic was used for fuzzification of Euclid's first postulate. Fuzzy equivalence relation "extended lines sameness" is introduced. For its approximation we also utilize a fuzzy conditional inference, which is based on proposed fuzzy "degree of indiscernibility" and "discernibility measure" of extended points. PMID- 27689134 TI - The Relationship between Body Mass Index and Depression among High School Girls in Ahvaz. AB - Objective. Today, obesity and depression are two major illnesses that are on the rise all over the world and threaten human health. This research was done to determine the relationship between Body Mass Index (BMI) and depression among Ahvaz high school female students. Method. In a descriptive-analytical study using stratified random sampling, 400 female high school students in academic year of 2013-2014 were picked and their height and weight were measured. BMI was classified based on World Health Organization classification. To assess the severity of depression, Beck depression questionnaire was used. In order to analyze the data, descriptive statistics and Pearson correlation test were used. Results. In terms of BMI 9% of students were slim, 77% were at an acceptable level, and 14% were overweight. Also, the prevalence of depression was 86.20% major depression and 13.79% moderate depression for obese persons, 10.41% major depression and 70.83% moderate depression for overweight persons, 8.78% major depression and 12.97% moderate depression for normal weight persons, and 9% moderate depression for slim persons. The relationship between BMI and depression among high school students is positive and significant (P < 0.001; r = 0.555). Conclusion. There is a positive and significant relationship between BMI and the severity of depression among Ahvaz high school female students.

Actinic keratoses (AKs), a premalignant skin lesion, are a common lesion in fair skin. Although destructive treatment remains the gold standard for AKs, medical therapies may be preferable due to the comfort and reliability .This study aims to compare the effects of topical 1% colchicine gel and 3% diclofenac sodium gel in AKs. Materials and Methods. In this randomized double-blind study, 70 lesions were selected. Patients were randomized before receiving either 1% colchicine gel or 3% diclofenac sodium cream twice a day for 6 weeks. Patients were evaluated in terms of their lesion size, treatment complications, and recurrence at 7, 30, 60, and 120 days after treatment. Results. The mean of changes in the size was significant in both groups both before and after treatment (<0.001). The mean lesion size before treatment and at 30, 60, and 120 days was not different between the two groups (p > 0.05). No case of erythema was seen in the colchicine group, while erythema was seen in 22.9% (eight cases) of patients in the diclofenac sodium group (p = 0.005). Conclusions. 1% colchicine gel was a safe and effective medication with fewer side effects and lack of recurrence of the lesion.

AB - Biodegradable zinc (Zn) metals, a new generation of biomaterials, have attracted much attention due to their excellent biodegradability, bioabsorbability, and adaptability to tissue regeneration. Compared with magnesium (Mg) and iron (Fe), Zn exhibits better corrosion and mechanical behaviors in orthopedic and stent applications. After implantation, Zn containing material will slowly degrade, and Zn ions (Zn2+) will be released to the surrounding tissue. For stent applications, the local Zn2+concentration near endothelial tissue/cells could be high. However, it is unclear how endothelia will respond to such high concentrations of Zn2+, which is pivotal to vascular remodeling and regeneration. Here, we evaluated the short-term cellular behaviors of primary human coronary artery endothelial cells (HCECs) exposed to a concentration gradient (0-140 MUM) of extracellular Zn2+. Zn2+ had an interesting biphasic effect on cell viability, proliferation, spreading, and migration. Generally, low concentrations of Zn2+ promoted viability, proliferation, adhesion, and migration, while high concentrations of Zn2+ had opposite effects. For gene expression profiles, the most affected functional genes were related to cell adhesion, cell injury, cell growth, angiogenesis, inflammation, vessel tone, and coagulation. These results provide helpful information and guidance for Zn-based alloy design as well as the controlled release of Zn2+in stent and other related medical applications. PMID- 27689138 TI - Characteristics of Cannabis-Only and Other Drug Users Who Visit the Emergency Department. AB - Emergency department (ED) settings have gained interest as venues for illegal drug misuse prevention and intervention, with researchers and practitioners attempting to capitalize on the intersection of need and opportunity within these settings. This study of 686 adult patients visiting two EDs for various reasons who admitted drug use compared daily cannabis-only users, nondaily cannabis-only users, and other drug users on sociodemographic and drug-related severity outcomes. The three drug use groups did not differ on most sociodemographic factors or medical problem severity scores. Forty-five percent of the sample was identified as having a drug use problem. ED patients who used drugs other than cannabis were at particular risk for high drug use severity indicators and concomitant problems such as psychiatric problems and alcohol use severity. However, 19-29% of cannabis-only users were identified as having problematic drug use. Furthermore, daily cannabis-only users fared less well than nondaily cannabis users with regard to drug use severity indicators and self-efficacy for avoiding drug use. Results may assist emergency medicine providers and medical social workers in matching patients to appropriate intervention. For example, users of drugs other than cannabis (and perhaps heavy, daily cannabis-only users) may need referral to specialty services for further assessment. Enhancement of motivation and self-efficacy beliefs could be an important target of prevention and treatment for cannabis-only users screened in the ED. PMID- 27689139 TI - Determinants of and Barriers to Hormonal and Surgical Treatment Receipt Among Transgender People. AB - Purpose: Medical gender confirmation therapy (GCT) plays an important role in transgender health; however, its prevalence and determinants constitute an area of uncertainty. Methods: Data for this cross-sectional study were obtained from an online survey distributed from October 2012 through the end of 2013 among persons who visited the social media sites of a transgender education and social networking meeting. Eligible respondents (n=280) were persons whose gender identity was different from their sex assigned at birth and who responded to questions about previously received or planned hormonal therapy (HT), chest reconstruction, or genital surgery. Multivariable logistic regression models examined how receipt and plans to receive different GCT types were associated with participants' characteristics and gender identity. Results: The respective percentages of ever and current HT were 58% and 47% for transwomen and 63% and 57% for transmen. Genital surgery was reported by 11 participants; all transwomen. Relative to transmen, transwomen were thrice more likely to report plans to undergo genital surgery. By contrast, transmen were more than 10 times as likely as transwomen to have had or planned chest surgery. Older participants and those who were in a committed relationship were less likely to plan future GCT. Having health insurance was not associated with GCT receipt. Treatment cost was named as the main problem by 23% of transwomen and 29% of transmen. Accessing a qualified healthcare provider for transgender-related care was listed as the primary reason for not receiving surgery by 41% of transmen and 2% of transwomen. Conclusions: Prevalence of GCT differed across subgroups of participants and was lower than corresponding estimates reported elsewhere. The variability of results may reflect differences in recruitment procedures and response rates; however, it is also possible that it may be driven by geographic, socioeconomic, and health related heterogeneity of the transgender population. PMID- 27689140 TI - Flexible growing rods: a biomechanical pilot study of polymer rod constructs in the stability of skeletally immature spines. AB - BACKGROUND: Surgical treatments for early onset scoliosis (EOS) correct curvatures and improve respiratory function but involve many complications. A distractible, or 'growing rod,' implant construct that is more flexible than current metal rod systems may sufficiently correct curves in small children and reduce complications due to biomechanical factors. The purpose of this pilot study was to determine ranges of motion (ROM) after implantation of simulated growing rod constructs with a range of clinically relevant structural properties. The hypothesis was that ROM of spines instrumented with polymer rods would be greater than conventional metal rods and lower than non-instrumented controls. METHODS: Biomechanical tests were conducted on six thoracic spines from skeletally immature domestic swines (35-40 kg). Paired pedicle screws were used as anchors at proximal and distal levels. Specimens were tested under the following conditions: control, then dual rods of polyetheretherketone (PEEK) (diameter 6.25 mm), titanium (4 mm), and cobalt-chrome alloy (CoCr) (5 mm). Lateral bending (LB) and flexion-extension (FE) moments were applied, and vertebral rotations were measured. Differences were determined by two-tailed t tests and Bonferroni for four primary comparisons: PEEK vs control and PEEK vs CoCr, in LB and FE (alpha = 0.05/4). RESULTS: In LB, ROM of spine segments after instrumenting with PEEK rods was lower than the non-instrumented control condition at each instrumented level. ROM was greater with PEEK rods than with Ti and CoCr rods at every instrumented level. Combining treated levels, in LB, ROM for PEEK rods was 35 % of control (p < 0.0001) and 270 % of CoCr rods (p < 0.01). In FE, ROM with PEEK was 27 % of control (p < 0.001) and 180 % of CoCr (p < 0.01). At proximal and distal adjacent non-instrumented levels in FE, mean ROM was lower for PEEK than for either metal. CONCLUSIONS: PEEK rods increased flexibility versus metal rods, and decreased flexibility versus non-instrumented controls, both over the entire instrumented segment and at each individual level. Smaller mean increases in ROM at proximal and distal adjacent motion segments occurred with PEEK compared to metal rods, which may help decrease complications, such as junctional kyphosis. Flexible growing rods may eventually help improve treatment options for young patients with severe deformity. PMID- 27689141 TI - Adjuvant Aromatase Inhibitors in Early Breast Cancer May Not Increase the Risk of Falls. AB - BACKGROUND: Falling increases the risk for fracture. The impact of adjuvant aromatase inhibitors (AI) on the risk of falls is undefined. METHODS: A retrospective case control study was performed examining women with early stage breast cancer on adjuvant AI and matched controls without cancer. Fall and fracture data were abstracted from the medical record. RESULTS: Matched pairs of 332 women were identified (total N = 664). There was no statistically significant difference in the odds of a fall between cases and controls, p = 0.86. Similarly, the odds of a fracture between cases and controls was not significantly different, p = 1.0. There were 35 pairs in which the case fractured but the control did not and equal number of pairs where the control fractured but the case did not. For pairs in which control fractured but case did not, the median age at fracture was significant higher than that for pairs in which case fractured but the control did not (71 vs. 63 years p = 0.0003). CONCLUSION: This study did not identify a difference in the incidence of falls or fractures in women on adjuvant AI compared to their age matched controls without breast cancer. Prospective studies of falls and fracture in women on adjuvant AI therapy compared to age match controls would aid in the identification of fracture risk. PMID- 27689142 TI - Editorial.

PMID- 27689143 TI - Accuracy of Contrast-Enhanced Ultrasound in the Diagnosis of Bile Duct Obstruction. AB - PURPOSE: To investigate the ability of contrast-enhanced ultrasound (CEUS) to differentiate benign from malignant lesions causing biliary duct obstruction. MATERIALS AND METHODS: Between November 2006 and December 2013, 59 patients with bile duct obstruction of undetermined cause in baseline ultrasound underwent CEUS study. The enhancement and posterior washout were analyzed in real time all along the study duration (5'). The final diagnosis suggested by CEUS was compared with histologic diagnosis (47.5%) or with radiologic follow-up with TC, RM or ERCP. RESULTS: Final diagnoses included 42 malignant lesions (cholangiocarcinoma n=22, metastases n=6, pancreatic carcinoma n=6, hepatocarcinoma n=4, gallbladder carcinoma n=2, ampullary carcinoma n=1 and lymphoma n=1) and 17 benign lesions (lithiasis or biliary sludge n=15, xanthogranulomatous cholecystitis n=1 and indeterminate n=1). CEUS accuracy compared with final diagnoses based on combined reference standard was 86.4%. CEUS correctly identified 36 of 42 malignant lesions (sensibility 85.7%) and 15 of 17 benign lesions (specificity 88.2%). The positive predictive value of CEUS for malignancy was 94.7%, while the negative predictive value was 71.4%. CONCLUSION: CEUS is useful to differentiate between benign and malignant causes of obstructive jaundice. This technique improves the detection of bile duct invasion in hepatic neoplasms and permits better evaluation of intra- and extraductal extension of hilar hepatobiliary tumors. PMID- 27689144 TI - Assessment of Ultrasound Features Predicting Axillary Nodal Metastasis in Breast Cancer: The Impact of Cortical Thickness. AB - PURPOSE: To evaluate the accuracy of axillary ultrasound (AUS) in detecting nodal metastasis in patients with early-stage breast cancer and to identify AUS features with high predictive power. MATERIALS AND METHODS: Prospective single center preliminary study in 105 patients with a primary diagnosis of breast cancer and clinically negative axilla. AUS was performed using a 12 MHz linear array transducer before ultrasound-guided needle biopsy. Nodal characteristics (shape, longitudinal-transverse [LT] axis ratio, margins, cortical thickness, hyperechoic hilum) were correlated with histopathological nodal status after SLNB or axillary lymph node dissection (ALND). RESULTS: Nodal metastases were present in 42/105 patients (40.0%). Univariate analyses showed that absence of hyperechoic hilum, round shape, LT axis ratio<2, sharp margins and cortical thickness>3 mm were associated with lymph node metastasis. Multivariate logistic regression analysis revealed cortical thickness > 3 mm as an independent predictive parameter for nodal involvement. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 66.7, 74.6, 63.6, 77.0% and 71.4% respectively when cortical thickness > 3 mm was applied as the criterion for AUS positivity. Axillary tumor volume was low in patients with pT1/2 tumors and negative AUS, since only 3.2% of patients had > 2 metastatic lymph nodes. CONCLUSION: Cortical thickness>3 mm is a reliable predictor of nodal metastatic involvement. Negative AUS does not exclude lymph node metastases, but extensive axillary tumor volume is rare.

The aim of the study was to evaluate cut-off values and performance of ARFI measurements in children using transient elastography as a reference. METHODS/PATIENTS: A total of 198 children were enrolled in this study. All patients underwent liver stiffness measurements with FS (FS-LS) as well as ARFI (with shear wave velocity quantification; ARFI-SWV) and the performance of ARFI in comparison to FS was studied. RESULTS: Significantly higher rates of successful measurements were found for ARFI compared to FS (198/198 (100%) vs. 160/198 (80.8%); p<0.001). ARFI-SWV correlated significantly with FS-LS (r=0.751, p=0.001). ARFI-SWV increased significantly with the stage of fibrosis (1.19+0.15 m/s for patients with FS-LS<7.6 kPa); 1.34+0.22 m/s for patients with 7.613.0 kPa). ARFI-SWV cut off values were identified for no significant fibrosis (1.31 m/s; sensitivity 61.8% and specificity 79.5%) and for liver cirrhosis (1.63 m/s; sensitivity 70.0% and specificity 97.4%). The median values of liver stiffness measured by FS were age-dependent in 90 children without liver diseases with 4.8, 5.6, and 5.7 kPa in children 0-5, 6-11, and 12-18 years, respectively.

PMID- 27689151 TI - Common and Uncommon Presentation of Fluid within the Scrotal Spaces. AB - Ultrasonography(US) of the scrotum has been demonstrated to be useful in the diagnosis of fluid in the scrotal sac. Grayscale US characterizes the lesions as testicular or extratesticular and, with color Doppler, power Doppler and pulse Doppler, any perfusion can also be assessed. Cystic or encapsulated fluid collections are relatively common benign lesions that usually present as palpable testicular lumps. Most cysts arise in the epidydimis, but all anatomical structures of the scrotum can be the site of their origin. US may suggest a specific diagnosis for a wide variety of intrascrotal cystic and fluid lesions and appropriately guide therapeutic options. The paper reviews the current knowledge of ultrasound in conditions with fluid in the testis and scrotum. The review presents the applications of ultrasonography in the diagnosis of hydrocele, testicular cysts, epididymal cysts, spermatoceles, tubular ectasia, hernia and hematoceles. The aim of this paper is to provide a pictorial review of the common and uncommon presentation of fluid within the scrotal spaces. PMID- 27689149 TI - Single Nucleotide Polymorphism-Based Analysis of Cell-Free Fetal DNA in 3000 Cases from Germany and Austria. AB - BACKGROUND & PATIENT: Data from 3 008 patients, who underwent single-nucleotide polymorphism (SNP)-based noninvasive prenatal testing (NIPT) are presented. METHOD: The PanoramaTM test (Natera, San Carlos, CA) was used to analyze cell free fetal DNA from maternal blood for trisomies 21, 18, and 13, triploidy and sex-chromosome aneuploidies. RESULT: In 2 942 (97.8%) cases, a result was obtained. The average fetal fraction was 10.2%. A high-risk result for fetal aneuploidy was made for 65 (2.2%) cases. In 59 (90.8%) of these cases, invasive testing confirmed the aneuploidy. There were 6 false-positive cases. In the false positive group, the fetal fraction was significantly lower. The overall positive predictive value was 90.8%. No false-negative cases were reported but many patients in this study have not delivered yet. Therefore, exact data cannot be given for potential false-negative cases. CONCLUSION: SNP-based NIPT is a reliable screening method for evaluating the risk of aneuploidies of chromosomes 21, 18 and 13. By using NIPT, the number of invasive procedures may be reduced significantly compared to maternal age and first-trimester screening. PMID- 27689152 TI - Positive Predictive Value of Abdominal Sonography in the Diagnosis of Ischemic Colitis. AB - AIM: The aim was to prospectively evaluate the positive predictive value of ultrasound in the diagnosis of ischemic colitis, with colonoscopy as the reference standard. METHODS: During a 2-year period we included consecutive patients over 50 years of age with sudden abdominal pain and/or rectal bleeding who underwent abdominal sonography in an emergency setting with a thickened segment of colon with a length of more than 10 cm. This clinical-sonographic triad was considered diagnostic for ischemic colitis. A thickened bowel location or color Doppler flow findings on ultrasound examination were evaluated but were not considered to make the diagnosis of ischemic colitis. Basic descriptive statistics were used to characterize the study patients. The positive predictive value was calculated as: number of patients with the definitive diagnosis of ischemic colitis (colonoscopic or follow-up)/number of patients with a sonographic diagnosis of ischemic colitis. RESULTS: A total of 48 patients had the clinical-sonographic triad; mean age: 74.3 years (range 54-90 years). The most frequent clinical manifestation was rectal bleeding (83% of the cases) followed by abdominal pain (81%) and diarrhea (45%). A total of 42 cases of ischemic colitis were confirmed by endoscopy (n=35) and biopsy (n=34) or clinical evaluation (n=7). The positive predictive value of the clinical-sonographic diagnosis of ischemic colitis was 87.5%. Thickening of the colon wall was detected on the left side in 35 patients with ischemic colitis, on the right side in 3 and pancolitis was identified in 5 patients. CONCLUSION: In an appropriate clinical setting, ultrasound has a high positive predictive value for the diagnosis of ischemic colitis. PMID- 27689153 TI - A Protocol for Improved Measurement of Arterial Flow Rate in Preclinical Ultrasound. AB - PURPOSE: To describe a protocol for the measurement of blood flow rate in small animals and to compare flow rate measurements against measurements made using a transit time flowmeter. MATERIALS AND METHODS: Measurements were made in rat and mice using a Visualsonics Vevo 770 scanner. The flow rate in carotid and femoral arteries was calculated from the time-average maximum velocity and vessel diameter. A correction factor was applied to correct for the overestimation of velocity arising from geometric spectral broadening. Invasive flow rate measurements were made using a Transonics system. RESULTS: Measurements were achieved in rat carotid and femoral arteries and in mouse carotid arteries. Image quality in the mouse femoral artery was too poor to obtain diameter measurements. The applied correction factor in practice was 0.71-0.77. The diameter varied by 6 18% during the cardiac cycle. There was no overall difference in the flow rate measured using ultrasound and using transit-time flowmeters. The flow rates were comparable with those previously reported in the literature. There was wide variation in flow rates in the same artery in individual animals. Transit-time measurements were associated with changes of a factor of 10 during the typical 40 min measurement period, associated with probe movement, vessel spasm, vessel kinking and other effects. CONCLUSION: A protocol for the measurement of flow rate in arteries in small animals has been described and successfully used in rat carotid and femoral arteries and in mouse carotid arteries. The availability of a noninvasive procedure for flow rate measurement avoids the problems with changes in flow associated with an invasive procedure. PMID- 27689154 TI - The Posterior Cerebral Artery and its Main Cortical Branches Identified with Noninvasive Transcranial Color-Coded Duplex Sonography. AB - PURPOSE: To differentiate PCA segments and cortical branches by means of transcranial color-coded duplex sonography (TCCD) and to measure flow parameters at rest and during visual stimulation. MATERIALS AND METHODS: 60 healthy subjects with a good acoustic temporal bone window were examined. The main stem of the PCA (P1, P2 and P3) and 4 main cortical branches - the anterior temporal artery (ATA), the occipital temporal artery (OTA), the parietooccipital artery (POA) and the calcarine artery (CA) - were assessed using an axial transtemporal approach. Systolic and diastolic blood flow velocities (BFVs) were recorded at rest and during visual stimulation. RESULTS: Identification of the P1 segment of the PCA was successful in 97.5% (117/120) of cases. The P2 and P3 segments were visualized in all cases. The 4 main cortical branches could be identified to varying degrees: ATA in 88%, OTA in 96%, POA in 69% and CA in 62%. There was an evoked flow response in the P2 main stem and in all cortical branches. The most pronounced increase in diastolic/systolic BFV after visual stimulation test was seen in the CA (42%/35%), followed by P2 (30%/24%), the POA (27%/27%), the OTA (16%/13%) and the ATA (9%/8%). CONCLUSION: Insonation through the temporal bone window with TCCD confidently allows the assessment of the P1 to P3 segments of the PCA as well as the 2 proximal branches, the ATA and the OTA. An ultrasound based classification of PCA anatomy and its cortical branches may be used as a noninvasive method for the evaluation of posterior circulation pathology. PMID- 27689155 TI - Point-of-Care Clinical Ultrasound for Medical Students. AB - PURPOSE: Our institution has recently implemented a point-of-care (POC) ultrasound training program, consisting of an e-learning course and systematic practical hands-on training. The aim of this prospective study was to evaluate the learning outcome of this curriculum. MATERIALS AND METHODS: 16 medical students with no previous ultrasound experience comprised the study group. The program covered a combination of 4 well-described point-of-care (POC) ultrasound protocols (focus assessed transthoracic echocardiography, focused assessment with sonography in trauma, lung ultrasound, and dynamic needle tip positioning for ultrasound-guided vascular access) and it consisted of an e-learning course followed by 4 h of practical hands-on training. Practical skills and image quality were tested 3 times during the study: at baseline, after e-learning, and after hands-on training. RESULTS: Practical skills improved for all 4 protocols; after e-learning as well as after hands-on training. The number of students who were able to perform at least one interpretable image of the heart increased from 7 at baseline to 12 after e-learning, p<0.01, and to all 16 students after hands on-training, p<0.01. The number of students able to cannulate an artificial vessel increased from 3 to 8 after e-learning and to 15 after hands-on training. CONCLUSION: Medical students with no previous ultrasound experience demonstrated a considerable improvement in practical skill after interactive e-learning and 4 h of hands-on training.

AB - AIM: The actual occurrence of spontaneous plaque rupture in mice has been a matter of debate. We report on an in vivo observation of the actual event of possible plaque disruption in a living ApoE(-/-) mouse. METHODS AND RESULTS: During live contrast-enhanced ultrasonography of a 50-week-old ApoE(-/-) male mouse, symptoms suggesting plaque disruption in the brachiocephalic artery were observed. Histological analysis confirmed the presence of advanced atherosclerotic lesions with dissections and intraplaque hemorrhage in the affected brachiocephalic trunk, pointing towards plaque rupture as the cause of the observed event. However, we did not detect a luminal thrombus or cap rupture, which is a key criterion for plaque rupture in human atherosclerosis. CONCLUSION: This study reports the real-time occurrence of a possible plaque rupture in a living ApoE(-/-) mouse.

PMID- 27689161 TI - Is Sonographic Assessment of Intratendinous Blood Flow in Achilles Tendinopathy Patients Reliable?: Consistency of Doppler Ultrasound Modes and Intra- and Inter observer Reliability. AB - PURPOSE: The purpose of this study was to investigate the consistency between different Doppler ultrasound (DU) modes as well as the intra- and inter-observer reliability of investigators with different experience level in assessing intratendinous blood flow (IBF) in Achilles tendinopathy patients. MATERIAL AND METHODS: 18 participants (36 Achilles tendons, AT) with Achilles tendinopathy (24 AT) were examined with power Doppler ultrasound (PDU), colour Doppler ultrasound (CDU) and "Advanced Dynamic Flow" (ADF) (Toshiba Xario SSA-660 A; 14MHz transducer) by 2 investigators (experienced, EI; inexperienced, II) in a test retest design (M1/M2). A modified Ohberg score was used to quantify IBF. Data was analysed descriptively (absolute and relative). Consistency of the 3 modes was presented by Kendall's Coefficient of Concordance (Kendall's W). Intra- and inter observer reliability were calculated by use of Kendall's tau b correlation coefficient. RESULTS: IBF was detected in 79-92% of symptomatic AT and in 33-50% of contralateral asymptomatic AT. Comparing the 3 modes, Kendall's W ranged from 0.97-0.98. Analysis of intra-observer reliability resulted in Kendall's tau 0.90 0.92 for EI and 0.84-0.87 for II. Inter-observer reliability resulted in Kendall's tau 0.64-0.69 in M1 and 0.68-0.70 in M2. CONCLUSION: The very good consistency between PDU, CDU and ADF indicates a comparable applicability for assessing IBF in ATs. Intra-observer reliability was high for both investigators, independent of experience. The moderate inter-observer reliability reflects the challenge in sonographic detection of intratendinous blood flow (IBF) amount. PMID- 27689162 TI - Prenatal Risk Calculation (PRC) 3.0: An Extended DoE-Based First-Trimester Screening Algorithm Allowing For Early Blood Sampling. AB - AIM: Both previous versions of the German PRC algorithm developed by our group for routine first-trimester screening relied on the assumption that maternal blood sampling and fetal ultrasonography are performed at the same visit of a pregnant women. In this paper we present an extension of our method allowing also for constellations where this synchronization is abandoned through preponing blood sampling to dates before 11 weeks of gestation. METHODS: In contrast to the directly measured concentrations of the serum parameters PAPP-A and free beta hCG, the logarithmically transformed values could be shown to admit the construction of reference bands covering the whole range from 16 to 84 mm CRL [corresponding to 63 to 98 days of gestation]. Prior to determining reference limits from which the DoEs for each individual patient had to be calculated, the log concentrations of all PAPP-A and free beta-hCG values were transformed once more using the calibration approach established in 1 for the elimination of the influence of maternal weight. RESULTS: Although that part of the database which was available for estimating the reference bands for blood sampling times prior to 11 weeks of gestation was comparatively sparse (898 out of 186 215 pregnancies with euploid outcome), the key statistical characteristics of the extended risk calculation procedure turned out to be very satisfactory. Using the same cutoff value of 1:150 for the posterior risks of trisomy 21 and 13/18, the overall FPR (false positive rate) for diagnosing a T21 was found to be 3.42%. The corresponding DTR (detection rate) was obtained to be 86.8% and thus exceeded the DTR attained by PRC 2.0 for trisomy 21. For trisomies 13 and 18, the proportions of patients with calculated posterior risks exceeding the cutoff value of 1:150 were obtained to be 1.60% (=FPR) and 86.4% (=DTR). CONCLUSION: Transforming the measured concentrations of PAPP-A and free beta-hCG to the logarithmic scale allows one to extend the DoE-based algorithm developed by the FMF Germany for diagnosing trisomies 21 and 13/18 in such a way that it can be applied to constellations where blood sampling is done before 11 weeks of gestation. PMID- 27689163 TI - EFSUMB Statement on Medical Student Education in Ultrasound [long version]. AB - The European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) recommends that ultrasound should be used systematically as an easy accessible and instructive educational tool in the curriculum of modern medical schools. Medical students should acquire theoretical knowledge of the modality and hands-on training should be implemented and adhere to evidence-based principles. In this paper we report EFSUMB policy statements on medical student education in ultrasound that in a short version is already published in Ultraschall in der Medizin 1.

PMID- 27689167 TI - Determining Tarsus Curvature in Relation To Direction of Gaze Using Non-contact Ultrasound Video Assistance. AB - PURPOSE: Plastic surgery on the eyelids for the purpose of aesthetic or functional correction requires precise knowledge of lid anatomy. Changes in the tarsal curvature of the upper eyelid relative to line of vision are important, particularly when a surgical correction of paralytic lagophthalmos is undertaken. We used a computer-based image-processing algorithm to establish a relationship between changes in the curvature of the tarsus relative to the line of vision. MATERIAL AND METHODS: A dynamic, ultrasound examination of the upper eyelids of 100 participants (100 eyes) was performed transpalpebrally using a 7.5 MHz scanner with the patient looking straight ahead, away from and towards the midline of the body. A computer-aided examination of the upper eyelid tarsus was then performed, followed by the calculation of the radius of curvature of the tarsus relative to the line of vision in each position. RESULTS: Using regression of a Taylor polynomial, the shape of the tarsus was mapped by a quadratic function, and the change in tarsal curvature relative to line of sight could be demonstrated. CONCLUSION: With objective evidence of change in the tarsal curvature relative to the line of sight, this may influence the treatment of pathological changes in the upper eyelid.

AB - AIM: To describe two new ultrasound signs for thyroid nodules - "nodule in nodule" and "hypoechoic internal septae" and assess their usefulness in differentiating follicular variant of papillary thyroid carcinoma (FVPTC) from benign thyroid nodules (BTN). METHODOLOGY: Ultrasound findings of 210 patients with histopathologically proven FVPTC (68 nodules, M:F=13:47 with mean age of 39.5+/-11.9 years) and BTN (165 nodules, (M:F=41:109 with mean age of 44+/-11.3 years) were retrospectively reviewed from PACS by a single radiologist blinded to the final diagnosis. Logistic regression analysis was performed to identify the best predictors of FVPTC and their diagnostic performance was assessed. RESULTS: The "nodule in nodule" sign was seen in 80.9% of FVPTC and only 12.1% of BTN. The "hypoechoic internal septae" sign was seen in 44.1% of FVPTC and 17% of BTN. Younger patients, heterogeneous echotexture, nodule in nodule sign, thick incomplete non-uniform halo and presence of significant nodes were the best predictors of FVPTC (p<0.05). The sensitivity, specificity, positive predictive value, negative predictive value, accuracy and relative risk for FVPTC given as odds ratio (95% CI) for heterogeneous echotexture and nodule in nodule sign which were the best 2 predictors of FVPTC were 91.2%, 81.8%, 67.3%, 95.7%, 84.5%, 46.5 (18.5-117.4) and 80.9%, 87.7%, 74.3%, 91.2%, 86.2%, 32.5 (15.04-70.2), respectively. There was improvement in the specificity (91.5%) and accuracy (86.6%) when a combined criterion of heterogeneous echotexture and nodule in nodule sign was applied to predict FVPTC. CONCLUSION: The "nodule in nodule" sign is common in FVPTC and when combined with heterogeneous echotexture can differentiate FVPTC and BTN with high specificity. PMID- 27689171 TI - Very Early In-Utero Diagnosis of Walker-Warburg Phenotype: The Cutting Edge of Technology. AB - BACKGROUND: Walker-Warburg phenotype is a severe and lethal autosomal recessive disorder, belonging to a group of congenital malformations defined as abnormal pial basement membrane formation. So far, prenatal diagnosis was considered possible only during late pregnancy. METHODS: First trimester assessment of a pregnancy suspected to be affected by Walker-Warburg phenotype, using a high resolution transvaginal ultrasound probe (6-12 MHz), T2 MR imaging (1.5T), molecular genetics and histopathology. RESULTS: Very early diagnosis of the Walker-Warburg phenotype at 11 weeks of gestation proved possible by depicting the classic signs of this entity, confirmed by molecular genetics, post-abortion MR imaging and histopathology. CONCLUSION: Advancements in ultrasound equipment and technology, molecular genetics and histopathology have made very early detection of this syndrome possible, thus shedding new light on the natural history of this malformation. PMID- 27689169 TI - Ultrasonographic Differentiation of Lateral Elbow Pain. AB - Lateral elbow pain is often attributed to degenerative or posttraumatic impairment of the common extensor tendon. Ultrasonography assesses the soft tissue structures of the lateral elbow, allowing the differentiation between various underlying processes, including angiofibroblastic degeneration, hyaline degeneration, and inflammation, and exclusion of other possible causes of pain such as posterior interosseous and lateral antebrachial nerve compression. Furthermore, the real-time imaging nature of ultrasonography enables the detection of impingement of the lateral synovial fold, degenerative changes in the elbow recess, and elbow posterolateral instability during dynamic maneuvers. Ultrasonography is widely accessible and well tolerated by patients, making it a perfect method for establishing an initial diagnosis and monitoring the healing process. This review describes the possible causes of lateral elbow pain and their ultrasonographic differentiation.

AB - PURPOSE: To scrutinize the validity of a novel angle (maxilla-mandible-nasion angle, MMN) as objective proof of midfacial hypoplasia in trisomy 21 fetuses. MATERIALS AND METHODS: Volume data sets of 2(nd) trimester fetuses were reviewed in this retrospective study. After achievement of the correct midsagittal position, the fetal profile line (FP line) and the mandibulo-maxillary line (MML) were applied and the resulting angle was calculated. Additionally, the prefrontal space ratio (PFSR) was assessed. Both measurements were obtained from 401 euploid fetuses and 42 fetuses with trisomy 21. Values for MMN and PFSR<5(th) percentile were considered abnormal. RESULTS: The study included 443 fetuses with a mean gestational age of 21.3 weeks (range: 14.0-26.3). The MMN angle sufficiently identified hypoplasia of the midface in trisomy 21 fetuses (mean: 14.6 degrees ; range: 10.1 degrees - 22.0 degrees ) compared to controls (mean: 20.5 degrees ; range: 17.3 degrees -23.7 degrees ; p<0.0001). Concomitantly, the PFSR of Down syndrome fetuses was significantly lower (mean: 0.53; range: 0.21-1.22) than in euploid individuals (1.38; range: 0.54-2.23; p<0.0001). CONCLUSION: Calculation of the novel MMN angle in 2(nd) trimester fetuses reliably allows rapid assessment of craniofacial anatomy in order to rule out the midfacial hypoplasia frequently found in trisomy 21. PMID- 27689173 TI - Objective Assessment of Cervical Stiffness after Administration of Misoprostol for Intrauterine Contraceptive Insertion. AB - PURPOSE: The goal of this study was to objectively quantify cervical stiffness in misoprostol users prior to IUC insertion and at follow-up consultation to evaluate the feasibility of assessing cervical stiffness and to study the influence of misoprostol on cervical softening. MATERIALS AND METHODS: This was a cross-sectional study that evaluated 40 women who wished to use the LNG IUS. These women were evaluated immediately before LNG IUS insertion and 6 weeks later at follow-up consultation. Participants received 200 MUg of misoprostol combined with 75 mg of diclofenac in a single tablet orally (Arthrotec forte 75/200((r)), Pfizer, USA) 6-12 h prior to insertion in "off label" use. On both occasions, cervical stiffness was determined using a novel medical device based on the aspiration technique. The Wilcoxon rank-sum and the Wilcoxon signed-rank test were applied to compare cervical stiffness assessments at insertion of the IUD and at follow-up. RESULTS: For the first time, cervical stiffness was quantitatively assessed in misoprostol users prior to IUD insertion, proving that the aspiration technique enables detection of pharmacologically induced cervical changes, and also that misoprostol has a detectable softening effect on cervical tissue. CONCLUSION: The clinical value of the detected cervical softening after misoprostol administration remains unclear. Aspiration measurements could be helpful in searching for the ideal candidate, the appropriate route, dosage and interval of misoprostol intake prior to IUC insertion.

AB - AIM: The objective of this pilot study was to determine the accuracy of point-of care B-line lung ultrasound in comparison to NT Pro-BNP for screening acute heart failure. MATERIALS AND METHODS: An 8-zone lung ultrasound was performed by experienced sonographers in patients presenting with acute dyspnea in the ED. AHF was determined as the final diagnosis by 2 independent reviewers. RESULTS: Contrary to prior studies, B-line ultrasound in our study was highly specific, but moderately sensitive for identifying patients with AHF. There was a strong association between elevated NT-proBNP levels and an increased number of B-lines. CONCLUSION: In conclusion, point-of-care lung ultrasound is a helpful tool for ruling in or ruling out important differential diagnoses in ED patients with acute dyspnea. PMID- 27689181 TI - Clinical Data as an Adjunct to Ultrasound Reduces the False-Negative Malignancy Rate in BI-RADS 3 Breast Lesions. AB - PURPOSE: Ultrasound (US) is a well-established diagnostic procedure for breast examination. We investigated the malignancy rate in solid breast lesions according to their BI-RADS classification with a particular focus on false negative BI-RADS 3 lesions. We examined whether patient history and clinical findings could provide additional information that would help determine further diagnostic steps in breast lesions. MATERIALS AND METHODS: We conducted a retrospective study by exploring US BI-RADS in 1469 breast lesions of 1201 patients who underwent minimally invasive breast biopsy (MIBB) from January 2002 to December 2011. RESULTS: The overall sensitivity and specificity of BI-RADS classification was 97.4% and 66.4%, respectively, with a positive (PPV) and negative predictive value (NPV) of 65% and 98%, respectively. In 506 BI-RADS 3 lesions, histology revealed 15 malignancies (2.4% malignancy rate), which corresponds to a false-negative rate (FNR) of 2.6%. Clinical evaluation and patient requests critically influenced the further diagnostic procedure, thereby prevailing over the recommendation given by the BI-RADS 3 classification. CONCLUSION: Clinical criteria including age, family and personal history, clinical examination, mammography and patient choice ensure adequate diagnostic procedures such as short-term follow-up or MIBB in patients with lesions classified as US-BI-RADS 3.

PMID- 27689183 TI - Easy Pulsatile Phantom for Teaching and Validation of Flow Measurements in Ultrasound. AB - PURPOSE: To build a simple model to teach and validate non-pulsatile and pulsatile flow quantification in ultrasound. MATERIALS AND METHODS: The setting consists of the following connected components: (1) medical syringe pump producing an adjustable constant flow (ml/min), (2) modulator modifying constant flow to a reproducible pulsatile flow, (3) water tank containing a diagonal running silicone tube (0.5 mm inner diameter), and (4) a fixated ultrasound probe (L9 Linear Array 9 MHz, GE Logiq E9) measuring the flow inside the tube. Commercially available microbubbles suspended with physiological saline solution were used for ultrasonic visibility. Spectral Doppler of different flow profiles is performed. RESULTS: The syringe pump produces an adjustable, constant flow and serves as the reference standard. The filling volume of the tube system is 1.2 ml. Microbubbles are very well detected by ultrasound and can be used as an easy and clean blood mimicking substance. The modulator generates different physiological and pathological flow profiles. Velocities are similar to those found within human blood vessels. Thus, it is possible to train and validate flow measurements in ultrasound. CONCLUSION: The model produces non-pulsatile and various pulsatile flow profiles and allows validation of flow measurements. The compact size permits easy and economic setup for flow measurements in research, skills lab and continuing education.

AB - BACKGROUND AND AIMS: Inflammation plays an important role in the development of esophageal adenocarcinoma and its metaplastic precursor lesion, Barrett's esophagus. Toll-like receptor (TLR) 2 signalling and lysosomal function have been linked to inflammation-associated carcinogenesis. We examined the expression of TLR2 in the esophagus and the effect of long-term TLR2 activation on morphological changes and expression of factors involved in lysosomal function in a Barrett's esophagus epithelium cell line. METHODS: TLR2 expression in normal squamous esophagus, reflux esophagitis, Barrett's esophagus and esophageal adenocarcinoma biopsies was assessed with Q-RT-PCR, in situ hybridization and immunohistochemistry. Barrett's esophagus epithelium cells (BAR-T) were incubated with acid and bile salts in the presence or absence of the TLR2 agonist Pam3CSK4 for a period up to 4 weeks. Morphological changes were assessed with electron microscopy, while Q-RT-PCR was used to determine the expression of lysosomal enzymes (Cathepsin B and C) and factors involved in endocytosis (LAMP-1 and M6PR) and autophagy (LC3 and Rab7). RESULTS: TLR2 was expressed in normal squamous esophagus, reflux esophagitis, Barrett's esophagus but was most prominent in esophageal adenocarcinoma. Long-term TLR2 activation in acid and bile salts exposed BAR-T cells resulted in more and larger lysosomes, more mitochondria and increased expression of LAMP-1, M6PR, Cathepsin B and C when compared to BAR-T cells incubated with acid and bile salts but no TLR2 agonist. Factors associated with autophagy (LC3 and Rab7) expression remained largely unchanged. CONCLUSION: Activation of TLR2 in acid and bile salts exposed Barrett epithelium cells resulted in an increased number of mitochondria and lysosomes and increased expression of lysosomal enzymes and factors involved in endocytosis. PMID- 27689191 TI - The Efficacy of Virtual Chromoendoscopy in the Diagnosis of Portal Hypertensive Gastropathy. AB - BACKGROUND: Diagnosis of portal hypertensive gastropathy (PHG) is based on endoscopic criteria. I-scan technology, a new technique of virtual chromoendoscopy, increases the diagnostic accuracy for lesions in the gastrointestinal tract. AIM: To establish the role of i-scan endoscopy in the diagnosis of PHG. METHOD: In this prospective study, endoscopic examination was conducted first by using white light and after that i-scan 1 and i-scan 2 technology in a group of 50 consecutive cirrhotic patients. The endoscopic diagnostic criteria for PHG followed the Baveno criteria. The interobserver agreement between white light endoscopy and i-scan endoscopy was determined using Cohen's kappa statistics. RESULTS: Forty-five of the 50 patients met the diagnostic criteria for PHG when examined by i-scan endoscopy and 39 patients were diagnosed with PHG by white light endoscopy. The strength of agreement between the two methods for the diagnosis of PHG was moderate (k=0.565; 95%CI 0.271-0.859; p<0.001). I-scan 1 classified the mosaic pattern better than classic endoscopy; i-scan 2 described better the red spots. CONCLUSION: I-scan examination increased the diagnostic sensitivity of PHG. The diagnostic criteria (mosaic pattern and red spots) were easier to observe endoscopically using i-scan than in white light. PMID- 27689190 TI - A Novel Potassium-Competitive Acid Blocker Improves the Efficacy of Clarithromycin-containing 7-day Triple Therapy against Helicobacter pylori. AB - BACKGROUND AND AIMS: In Japan, 7-day triple therapy for Helicobacter pylori including clarithromycin (CAM) was approved in 2000. However, antibiotic resistance subsequently reduced this rate to an unacceptable level (70%). Vonoprazan, an orally bioavailable potassium-competitive acid blocker (P-CAB), was approved in Japan in 2014. This could improve eradication rates by increasing the intragastric pH, thus increasing bacterial antibiotic susceptibility. This study compared the efficacy of 7-day triple therapies that included CAM and vonoprazan or proton pump inhibitor (PPI). METHODS: We prospectively analyzed H. pylori eradication rates in 146 patients receiving 7-day triple therapy containing P-CAB (April 2015 to September 2015), and in a retrospective cohort of 1,305 patients who received 7-day triple therapy containing a PPI (April 2011 to September 2015). RESULTS: H. pylori was eradicated in a significantly higher number of P-CAB-treated patients (89.7% [131/146]) than PPI-treated patients (73.9% [965/1305]; p < 0.05). The eradication rates in P-CAB-treated CAM sensitive and CAM-resistant bacteria were 100% (44/44) and 87.5% (28/32), respectively, which were significantly higher than the corresponding rates in PPI treated patients (88.0% [22/25] and 53.8% [7/13], p < 0.05). CONCLUSION: P-CAB improved the efficacy of CAM-containing 7-day triple therapy and would be a valuable first-line treatment for H. pylori infection. PMID- 27689192 TI - Superiority of a Split-dose Regimen of Sodium Picosulfate/Magnesium Citrate (SPMC) in Comparison to a Prior-day Schedule (AM/PM) for Colonoscopy Preparation. A Randomized Single-blinded Study. AB - BACKGROUND AND AIMS: Split-dose regimens are generally recommended for bowel cleansers. However, other regimens still remain in the summary of product characteristics of some bowel cleansers in Europe. The aim of this study is to compare the efficacy and safety of a split-dose regimen of sodium picosulfate/magnesium citrate (SPMC) with a prior-day schedule (AM/PM). METHODS: Multicenter, randomized (EudraCT no. 2013-001620-20), endoscopist-blinded, parallel study, carried out in subjects 18 years or older undergoing elective colonoscopy. The primary endpoint was the bowel cleansing assessment using a binary transformation (adequate/inadequate) of the Global Preparation Assessment (GPA) scale. Additional parameters analyzed were the segmental assessment of bowel cleansing (RSS), the adenoma detection rate and safety evaluations. RESULTS: 315 subjects comprised the ITT set. A significantly higher proportion of patients in the split-dose regimen had an adequate bowel preparation (AM/PM: 30.8% vs split-dose: 79.9%; p<0.0001). The mean global RSS was significantly lower in the split-dose group (AM/PM: 5.0 [SD: 2.91] vs split-dose: 2.6 [SD: 2.14]; p<0.0001). Flat polyps were detected in a higher proportion of subjects in the split-dose group compared with the AM/PM group (AM/PM: 16.0% vs split-dose: 22.0%). Both regimens were equally safe and well tolerated, with no serious treatment-emergent adverse events or discontinuations due to adverse events. CONCLUSION: A split-dose regimen of SPMC is superior to the AM/PM regimen administered the day before colonoscopy. Split regimen of SPMC should be considered the standard of use. PMID- 27689193 TI - Should we Investigate Gastroenterology Patients for Pancreatic Exocrine Insufficiency? A Dual Centre UK Study. AB - BACKGROUND AND AIMS: Pancreatic exocrine insufficiency may be under recognised in gastroenterological practice. We aimed to identify the prevalence of pancreatic insufficiency in secondary care gastroenterology clinics and determine if co morbidity or presenting symptoms could predict diagnosis. A secondary aim was to assess response to treatment. METHODS: A dual centre retrospective analysis was conducted in secondary care gastroenterology clinics. Patients tested for pancreatic exocrine insufficiency with faecal elastase-1 (FEL-1) between 2009 and 2013 were identified in two centres. Demographics, indication and co-morbidities were recorded in addition to dose and response to pancreatic enzyme replacement therapy. Binary logistic regression was used to assess if symptoms or co morbidities could predict pancreatic insufficiency. RESULTS: 1821 patients were tested, 13.1% had low FEL-1 (<200ug/g). This prevalence was sub-analysed with 5.4% having FEL-1 100-200ug/g (mild insufficiency) and 7.6% having faecal elastase readings <100ug/g. Low FEL-1 was most significantly associated with weight loss or steatorrhoea. Co-morbidity analysis showed that low levels were significantly associated with excess alcohol intake, diabetes mellitus or human immunodeficiency virus; 80.0% treated with enzyme supplements reported symptomatic benefit with no difference in response between high and low dose supplementation (p=0.761). CONCLUSION: Targeting the use of FEL-1 in individuals with specific symptoms and associated conditions can lead to improved recognition of pancreatic exocrine insufficiency in a significant proportion of secondary care patients. Intervening with lifestyle advice such as smoking cessation and minimising alcohol intake could improve outcomes. In addition, up to 80% of patients with low faecal elastase respond to supplementation. PMID- 27689194 TI - Single Nucleotide Polymorphisms within the 8Q24 Region are Not Associated with the Risk of Intraductal Papillary Mucinous Neoplasms of the Pancreas. AB - BACKGROUND AND AIMS: Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas have been reported to be associated with an increased risk of developing extra-pancreatic malignancies. A common genetic background has been hypothesised to be responsible for such an association. Human chromosomal region 8q24 has been associated with many types of cancer. The majority of these associations lie at approximately 128 Mb on chromosome 8. We conducted a study in order to examine the association between IPMN and single nucleotide polymorphisms (SNPs) from the 8q24 region, namely rs10505477, rs6983267, rs7014346, rs6993464, previously reported to influence general cancer susceptibility. METHODS: The study was performed on 117 IPMN cases and 231 controls. Cases were enrolled at the Digestive Endoscopy Unit, Policlinico Agostino Gemelli from January, 2010 to June, 2011, with either a prevalent or incident IPMN diagnosis. Status of SNPs was determined using a StepOne Real-time PCR system (Applied Biosystems) and TaqMan SNP Genotyping AssayTM 40X. Unconditional multiple logistic regression models were used to estimate odds ratios and 95% confidence intervals for the association of selected SNPs and IPMNs. RESULTS: Cases were more likely to report a 1st degree family history of cancer (p<0.001), as well as heavy smoking (p=0.001) and heavy drinking habits (p<0.001). No significant association was observed between IPMN and selected SNPs. The results were confirmed also when stratified according to any 1st-degree family history of cancer. CONCLUSION: Patients with IPMN do not have a higher prevalence of SNPs in the human chromosomal region 8q24 in respect to the control population. PMID- 27689195 TI - Pre-operative Diagnosis of Pancreatic Neuroendocrine Tumors with Endoscopic Ultrasonography and Computed Tomography in a Large Series. AB - BACKGROUND AND AIMS: Diagnosis of pancreatic neuroendocrine tumors (p-NETs) is frequently challenging. We describe a large series of patients with p-NETs in whom both pre-operative Computed Tomography (CT) and Endoscopic Ultrasonography (EUS) were performed. METHODS: This was a retrospective analysis of prospectively collected sporadic p-NET cases. All patients underwent both standard multidetector CT study and EUS with fine-needle aspiration (FNA). The final histological diagnosis was achieved on a post-surgical specimen. Chromogranin A (CgA) levels were measured. RESULTS: A total of 80 patients (mean age: 58 +/- 14.2 years; males: 42) were enrolled. The diameter of functioning was significantly lower than that of non-functioning p-NETs (11.2 +/- 8.5 mm vs 19.8 +/- 12.2 mm; P = 0.0004). The CgA levels were more frequently elevated in non functioning than functioning pNET patients (71.4% vs 46.9%; P = 0.049). Overall, the CT study detected the lesion in 51 (63.7%) cases, being negative in 26 (68.4%) patients with a tumor /=2), advanced fibrosis (F>/=3) and cirrhosis (F=4), respectively, we used the cutoffs of 7.0, 9.5 and 12.0 kPa. The diagnostic performance of ElastPQ(r) was assessed using the area under the ROC (AUROC) curve analysis and was evaluated overall and for cases with (a) 10 measurements and IQR/M30%, (d) 5 measurements and IQR/M>30%. RESULTS: The optimal cutoffs of ElastPQ(r) for significant fibrosis, advanced fibrosis and cirrhosis were 6.43, 9.54 and 11.34 kPa, respectively. For measurements with an IQR/M/=2, F>/=3, and F=4, respectively). CONCLUSION: The ElastPQ(r) technique is reliable and accurate for staging liver fibrosis. The number of measurements does not affect the performance. PMID- 27689199 TI - Analysis of p53 Protein Expression in Hepatocellular Carcinoma. AB - BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) has a growing incidence and studies regarding the risk factors or pathogenesis for this type of carcinoma benefit special interest. This study evaluates the correlations between p53 protein expression and clinical and laboratory factors in patients with HCC. METHODS: The study group included 76 patients diagnosed with HCC, either by biopsy or after surgical resection (with curative intent). Immunohistochemistry for p53 protein assessment was performed in all patients. Correlations between the protein 53 expression and age, tumour size, viral infection, liver cirrhosis were performed using the chi-square test (Pearson's chi-square) together with the contingency coefficient Kendall's coefficient in the tau-b form. RESULTS: In the study group, 51 patients were male (67%) and 25 female (33%). Cirrhosis due to hepatitis virus B or C infection (in a proportion of 63% of the study group) was not significantly associated with the presence of HCC. Altered expression of p53 protein was observed in 69 patients (91%). The relationship between p53 protein expression and patient sex (p=0.067), age (p=0.531), tumour size (p=0.270), presence of hepatitis B and C viral infections (p=0.7), and of liver cirrhosis (p=0.511) was not statistically significant. CONCLUSION: The p53 protein expression was not significantly associated with the demographic characteristics of the patients, tumour size, presence of viral B and C infections or liver cirrhosis. PMID- 27689200 TI - Mucin Genes Expression in the Intestine of Crohn's Disease Patients: a Systematic Review and Meta-analysis. AB - BACKGROUND AND AIMS: The mucus layer of the intestinal tract is the main barrier between luminal microbes and the mucosa, and has an essential role in the body defense mechanisms. Previous research could not establish consistent results for mucin genes expression in Crohn's disease (CD) patients. In this meta-analysis we looked at the mucin expression in CD patients and compared it with healthy controls. METHOD: English medical literature searches were conducted for mucin expression in the mucosa of the ileum and colon of CD patients and compared it with normal mucosa. Case-control studies were included. Meta-analysis was performed by using Comprehensive meta-anaslysis software. Pooled odds ratios and 95% confidence intervals were calculated. RESULTS: We found 160 eligible studies. Twenty studies were rejected because they have been performed in animals or did not have full text, and 134 studies were excluded because of language, being editorials, review articles, or because of duplications. We were left with 6 case control studies from 4 countries that fulfilled the inclusion criteria, published till 31.12.2015. No significant heterogeneity was demonstrated: Q = 149.256, df (Q) = 40.00, I2= 73.2% (less than 75%). We found a decrease of 34% in the total mucin expression in CD patients (Odds Ratio 0.660, 95% CI 0.486-0.897, P = 0.008). We also found a significantly decreased expression in CD patients for MUC5AC, MUC5B and MUC7. CONCLUSION: We demonstrated a global decrease in mucin expression in CD patients when compared with healthy controls. PMID- 27689198 TI - Prognostic Value of Metabolic Liver Function Tests: a Study on 711 Cirrhotic Patients. AB - BACKGROUND AND AIMS: The prognosis of cirrhotic patients is usually assessed by Child-Pugh and MELD scores. Metabolic liver function tests such as aminopyrine breath test (ABT) and indocyanine green clearance (IGC) have been shown to reveal hepatocellular dysfunction. The aim of this retrospective study was to compare the prognostic value of the MELD score, Child-Pugh score, ABT and IGC in a large cohort of cirrhotic patients. METHODS: Between January 1996 and June 2008, 711 cirrhotic patients were included and the primary endpoint was survival without LT. The ROC curves with c-statistics, correlation coefficient and survival were calculated. RESULTS: Metabolic function tests and scores were strongly correlated. At the time of evaluation, 111 patients had died and 520 had received a transplant. Prognostic ability (estimated by the AUROC curve) to predict survival without LT at 6 months was 0.662, 0.691, 0.738 and 0.715 for ABT, IGC, Child-Pugh score and MELD score, respectively. Similarly, at 1 year, AUROC was 0.738 for Child-Pugh score, 0.716 for MELD score, 0.693 for IGC clearance and 0.651 for ABT. CONCLUSIONS: Our results strongly confirm that IGC and ABT have a high prognostic value in cirrhotic patients, similar to Child-Pugh and MELD scores. They could be developed to routinely evaluate the prognosis of patients in addition to clinical and biochemical data. PMID- 27689201 TI - Psychological Interventions for Irritable Bowel Syndrome. AB - Irritable bowel syndrome (IBS) patients often present psychoform symptoms or psychiatric disorders. Among the psychological factors studied in IBS patients, two seem to influence mostly its severity: catastrophizing and somatization. Somatization is an independent risk factor for IBS. In addition, somatization more than the severity of IBS influences the way the patients perceive their illness, the outcome and the efficacy of treatment. Irritable bowel syndrome patients demonstrate greater catastrophizing scores than controls, and pain catastrophizing is a significant predictor of gastrointestinal symptoms related to pain. In this context we analysed the data regarding the efficacy of two psychological treatments in IBS: cognitive behavioral therapy and hypnosis. Cognitive behavioral therapy is focused on replacing maladaptive coping strategies with more positive cognitions and behaviors. Several studies showed that cognitive behavioral therapy is effective in reducing bowel symptoms in IBS, both post-treatment and short-term follow-up. Gut-directed hypnotherapy has beneficial short-term effects in improving gastrointestinal symptoms of patients with IBS, and the results are maintained after one year in half of the patients. Psychological treatments are a suitable option for selected IBS patients. PMID- 27689202 TI - Gastrointestinal Side Effects of Post-Transplant Therapy. AB - Modern immunosuppressive therapy has produced a real revolution in renal and organ transplantation but it comes with the price of multiple side effects. There are many gastrointestinal (GI) complications that are the consequence of transplant immunosuppressant medication. In fact, for any immunosuppressant therapy, certain standardized precepts and attitudes that aim to reduce the incidence and the impact of the medication side effects must be applied. Many patients undergo renal transplantation and the physicians have to be aware of the advantages and the risks associated. This article reviews the main GI complications that may arise as a consequence of immunosuppressive therapy after solid organ transplantation, focusing on renal and renal/pancreas transplantation, as well as the ways in which the incidence of these complications can be reduced. Management of the post-transplant therapy is mandatory in order to increase not only the grafts' and the patients' survival, but also their quality of life by the occurrence of fewer complications. PMID- 27689203 TI - Magnetic Nanoparticles for Hepatocellular Carcinoma Diagnosis and Therapy. AB - Hepatocellular carcinoma (HCC) is the most common primary tumor of the liver, ranking as the second most common cause of death from cancer worldwide. Magnetic nanoparticles (MNPs) have been used so far in tumor diagnosis and treatment, demonstrating great potential and promising results. In principle, three different approaches can be used in the treatment of tumors with superparamagnetic iron oxide nanoparticles: magnetically induced hyperthermia, drug targeting and selective suppression of tumor growth. This review focuses on the use of iron oxide nanoparticles for the diagnosis and treatment of liver cancer and offers a walkthrough from the MNPs imaging applicability to further therapeutic options, including their potential flaws. The MNP unique physical and biochemical properties will be mentioned in close relationship to their subsequent effects on the human body, and, also, their toxic potential will be noted. A presentation of what barriers the MNPs should overcome to be more successful will conclude this review. PMID- 27689204 TI - Serendipity in Refractory Celiac Disease: Full Recovery of Duodenal Villi and Clinical Symptoms after Fecal Microbiota Transfer. AB - Treatment of refractory celiac disease type II (RCD II) and preventing the development of an enteropathy associated T-cell lymphoma in these patients is still difficult. In this case report, we describe a patient with RCD II who received fecal microbiota transfer as treatment for a recurrent Clostridium difficile infection, and remarkably showed a full recovery of duodenal villi and disappearance of celiac symptoms. This case suggests that altering the gut microbiota may hold promise in improving the clinical and histological consequences of celiac disease and/or RCD II. PMID- 27689205 TI - Non-gastric Gastrointestinal Xanthomas: Case Series and Literature Review. AB - Gastrointestinal xanthomas are infrequent non-neoplastic lesions characterized by the accumulation of foam cells in the lamina propria. They are commonly seen in association with dyslipidemia, chemotherapy or radiotherapy, and infections in immunosuppressed patients. However, no clear connection to hyperlipidemia has been found. They occur more frequently in the stomach, and are very rare in the small bowel and esophagus. We identified all cases of non-gastric xanthoma or xanthomatosis reported in the English literature by searching the PubMed database and retrospectively reviewed the clinical, endoscopic, and histopathologic features of the 11 cases of non-gastric gastrointestinal xanthomas diagnosed in our hospital. Nine lesions were located in the large bowel, one in the duodenum and one in the esophagus. All xanthomas were small (<5 mm) sessile polyps except the esophageal xanthoma, which measured 13 mm. Two cases in the large bowel and the case in the small bowel were multiple. Most patients with large bowel xanthomas had hypercholesterolemia, unlike esophageal and small bowel cases. The esophageal lesion occurred in a patient with a history of partial fundoplication due to gastroesophageal reflux disease and the small bowel case was associated to chronic atrophic gastritis with intense activity. In our search of the English literature, we found 19 cases of xanthoma or xanthomatosis in the esophagus, 13 cases in the small bowel and 61 cases in the large bowel. In conclusion, gastrointestinal xanthomas, other than the gastric ones, are rare, and are usually incidental findings. PMID- 27689206 TI - Therapeutic Challenges for Symptomatic Portal Cavernoma Cholangiopathy. AB - Although transjugular intrahepatic portosystemic shunts are most frequently used for the management of portal hypertension, the surgical approach is preferred for symptomatic portal cavernoma cholangiopathy. We present the case of a 25-year old female patient with a portal cavernoma secondary to catheterization of the umbilical vein at birth. She had had two episodes of esophageal variceal bleeding, successfully treated by endoscopic banding. and an episode of acute cholangitis secondary to portal cavernoma cholangiopathy. Endoscopic sphincterotomy and biliary stenting were performed, and were followed by repeated episodes of biliary stent occlusion. The last biliary drainage procedure triggered a massive hemobilia. Since endoscopic therapy was ineffective, a surgical mesocaval shunt with graft interposition and splenectomy was performed with favorable outcome. In selected cases, the mesocaval shunting plays an essential role in the treatment of portal cavernoma cholangiopathy even in the era of interventional radiology. PMID- 27689207 TI - Multimodal Therapy including Yttrium-90 Radioembolization as a Bridging Therapy to Liver Transplantation for a Huge and Locally Advanced Intrahepatic Cholangiocarcinoma. AB - Treatment of intrahepatic cholangiocarcinoma remains a major challenge. For an unresectable lesion without extrahepatic spread, liver transplantation could be a potential solution but it is still associated with poor oncologic results owing to the absence of effective neoadjuvant treatment. We report the case of a young man with locally advanced intrahepatic cholangiocarcinoma presenting with multiple intrahepatic metastases and vascular structure involvement. The lesion was significantly downstaged by a multimodal therapy including intra-arterial Yttrium-90 radioembolization, systemic chemotherapy and external radiotherapy, allowing liver transplantation. Three years after the procedure, oncologic outcome is excellent with no sign of recurrence. Multimodal therapy including Yttrium-90 radioembolization could be relevant as neoadjuvant treatment before liver transplantation for unresectable intrahepatic cholangiocarcinoma.

Minimization of iatrogenic trauma and associated injuries. INDICATIONS: Conservative treatment did not sufficiently improve clinical symptoms. This is true for progressive or persisting neurological deficits, as well as for persisting pain which alters the quality of the patient's life. Results of surgery are strongly dependent on the preoperative duration of symptoms. Paramount is the "timing" of surgery: poorer surgical results associated with increasing preoperative duration of symptoms. CONTRAINDICATIONS: Conservative treatment modalities have not been exhausted. SURGICAL TECHNIQUES: There are 2 technologies (endoscopic/microsurgical) and 5 different approach strategies (endoscopic: interlaminar, transforaminal; microsurgical: interlaminar, translaminar, extraforaminal), whereby the choice is determined by morphology and location of the herniated disc. All techniques are minimally invasive and lead to comparable clinical results. POSTOPERATIVE MANAGEMENT: For all techniques, patients are mobilized early. Light sports activities allowed after 2 weeks and return to work after about 4 weeks. RESULTS: Good clinical outcomes in meta analyses/large case series are between 80-95 %. PMID- 27689223 TI - [Autonomy and welfare in intensive care medicine : Practical approach in difficult situations]. AB - In intensive care units far-reaching decisions are often made at short notice that require the consent of the informed patient. If this is not possible due to the patient's condition, physicians and legal representatives must ascertain the previously expressed or presumed will of the patient and act accordingly. The legal principles are specified in the Patient Advance Directives Act and the Patient Rights Act. Any indications for medical treatment need a clearly defined aim of the therapy, which can be questioned during the progress of the disease. To avoid conflicts between patient autonomy and medical treatment, the aims of therapy must be regularly discussed with the patient, representatives or relatives and documented in a written form. Checklists can be useful for structured consultations, to promote transparency and to avoid misunderstandings. Ethics consultations can help to deescalate critical situations.

AB - BACKGROUND: Inadequate access to prevention and medical treatment for female sex workers (SW) represents a challenge for the German health system. Accessibility and care for SW in Bochum (Germany) through a cooperation between the Interdisciplinary Immunology Outpatient Clinic, Center for Sexual Health and Medicine of St. Josef's Hospital, the Bochum health department and the Madonna e.V. was the focus of this work. PATIENTS AND METHODS: Medical outreach services were provided for the diagnosis of sexually transmitted infections (STI) in SW in brothels in Bochum between August 2013 and January 2014. After clarification and verbal consent from the SW, free HIV, syphilis, chlamydia, gonorrhea and trichomoniasis tests were offered and carried out using pseudonyms for the SW. RESULTS: A total of 112 SW were reached (up to 55.4 % within the framework of the STI Outreach Study). Of the SW, 94.6 % had an immigrant background. The majority (61.3 %) of SW were between 20 und 29 years old. Only 19.0 % of the collective had health insurance. The following STIs were diagnosed: 12.5 % chlamydia, 6.2 % syphilis, 3.6 % gonorrhea, 3.6 % trichomoniasis, and 0.9 % HIV. These results were compared with results from STI studies in SW in Germany. Treatment was performed in accordance with the standards of the German STI Society. CONCLUSION: The offer improved the accessibility and the utilization of medical services by SW in Bochum. A further improvement of services is urgently needed. PMID- 27689226 TI - [Hypoglossal nerve stimulation in patients with CPAP failure : Evolution of an alternative treatment for patients with obstructive sleep apnea]. AB - Obstructive sleep apnea (OSA) is a common disease in western industrialized countries with increasing prevalence. Gold standard of therapy is nocturnal positive pressure ventilation by continuous positive airway pressure (CPAP). Due to complications and side effects of ventilation, therapy adherence is limited. Recently an alternative surgical treatment has become available for these patients, which uses established techniques to stimulate the hypoglossus nerve to open the upper airway during sleep. The aim of this work is to provide an overview of the history and current state of scientific knowledge of this therapy in the treatment of OSA. Currently, two systems are available on the market: respiratory-driven hypoglossal nerve stimulation (Inspire Medical Systems) and continuous hypoglossal nerve stimulation (ImThera Medical). For respiratory driven hypoglossal nerve stimulation, a solid body of evidence is available and the therapy has been investigated in numerous multicenter clinical studies with regard to safety and efficacy. Only a small number of publications is available for continuous hypoglossal nerve stimulation. At the end of the last century, promising clinical results were shown in the first patients treated with hypoglossal nerve stimulation. Consequent technological and scientific development of respiratory-driven hypoglossal nerve stimulation in recent years led to its implementation in today's clinical routine. This therapy significantly broadens the spectrum of therapies in the treatment of OSA, especially for patients with CPAP intolerance. PMID- 27689227 TI - [Endoscopic ear surgery - complement to microscopic ear surgery]. AB - Wullstein, the founder of modern microscopic ear surgery, already used an oto endoscope intraoperatively. However, it is only after the recent development of modern video-endoscopy with high definition, 4-k, and 3-dimensional imaging that endoscopically guided surgery of the middle ear is gaining some importance. Key ventilation routes like the isthmus tympani and the epitympanic diaphragma can be visualized far better by using an endoscope rather than a microscope. Going through the external meatus surgery of middle ear pathologies is possible without external incision. This type of primary endoscopic ear surgery has to be distinguished from secondary endoscopic ear surgery, where standard microscopic ear surgery is supplemented by endoscopic surgery. Having to hold the endoscope in one hand, surgery has to be performed single-handed, which is awkward. In case of extensive bone removal or excessive bleeding the view through the endoscope lense is obscured, the endoscope therefore cannot fully substitute the use of the microscope. It is however an interesting adjunct to microscopic ear surgery. PMID- 27689229 TI - [Not Available]. PMID- 27689228 TI - [Speech audiometry in expert assessment of hearing impairment]. AB - In the assessment process of hearing impairment the medical expert has to verify its causality and to quantify its severity as hearing loss in percentage. Based on the determined hearing loss in percentage, the degree of impairment/disability or, in the case of work-related noise-induced hearing loss, the reduction in earning capacity is estimated. In Germany the guideline for the expert assessment of work-related noise-induced hearing loss is the Konigstein Guideline. Currently, the 5th edition from 2012 is used. Here, the hearing loss quantification depends mainly on the results of speech audiometry. Based on the Freiburg speech test, the hearing loss in percentage is determined using approved tables. For patients with a mild hearing loss, typically characterized by a high frequency hearing loss, tone audiometry results are consulted additionally. Speech-in-noise tests are available and are frequently used to measure the benefit of hearing systems. They allow for the detection of these patients' hearing impairment, which generally occurs in noisy environments. The first suggestions for a table to determine hearing loss in noise in percent are available. In experimental studies it was shown that tests in quiet, other than the Freiburg speech test, can be used and the same tables can be applied. In this article the current use of speech audiometry for expert assessment is presented, and options of using further developed speech test material are discussed. PMID- 27689230 TI - [Prostate carcinoma + swelling of the leg = lymphedema : Is the equation correct?] AB - Prostate carcinomas are often associated with lymphedemas of the leg following surgical treatment. Lymphedema is treated using complete decongestive therapy (CDT) with manual lymph drainage and compressive bandaging or stockings. Lymphedema resulting from a distinct iliac lymph node metastasis is a rare condition. A 73-year-old patient with a diagnosed prostate carcinoma presented with distinct swelling in the right leg. Iliac and leg vein thrombosis could not be ruled out. An ultrasound image revealed a large lesion surrounding the right iliac arteries. The patient was treated using percutaneous transluminal angioplasty and a stent was implanted in the right external iliac vein. This resulted in an almost complete regression of the swelling in the leg within a short period of time. While lymphedema can generally be established by clinical examination, this specific case demonstrates that an additional vascular examination is advisable in the context of an underlying malignant condition.

AB - Circadian timekeeping is a ubiquitous mechanism that enables organisms to maintain temporal coordination between internal biological processes and time of the local environment. The molecular basis of circadian rhythms lies in a set of transcription-translation feedback loops (TTFLs) that drives the rhythmic transcription of core clock genes, whose level and phase of expression serve as the marker of circadian time. However, it has become increasingly evident that additional regulatory mechanisms impinge upon the TTFLs to govern the properties and behavior of the circadian clock. Such mechanisms include changes in chromatin architecture, interactions with other transcription factor networks, post transcriptional control by RNA modifications, alternative splicing and microRNAs, and post-translational regulation of subcellular trafficking and protein degradation. In this review, we will summarize the current knowledge of circadian clock regulation-from transcriptional to post-translational-drawing from literature pertaining to the Drosophila and murine circadian systems. PMID- 27689232 TI - Scale insect larvae preserved in vertebrate coprolites (Le Quesnoy, France, Lower Eocene): paleoecological insights. AB - Coprolites of terrestrial vertebrates from the Sparnacian Le Quesnoy locality (Ypresian, Eocene, MP7, 53 Ma; Oise, France) were examined for possible parasitic helminth eggs. The extraction of the coprolite components was performed by a weak acetolyse and a slide mounting in glycerin. This long examination did not reveal paleoparasite remains, which may be explained through several arguments. However, some pollen grains, some enigmatic components, and two well-preserved first instar cochineal nymphs (Hemiptera: Sternorrhyncha: Coccoidea) were evidenced in coprolites. Identified as Coccidae, these larvae are the earliest stage of the scale insect development ever reported as fossil, revealing the specific environment of preservation that fossilized scats may provide. These observations, combined to the coprolites morphotype, enable to ascribe the fossil scats producer to a small herbivorous mammal present in the deposit (early perissodactyls or Plesiadapidae). Regarding the ecology of extant representatives of Coccidae, this mammal was a likely foliage consumer, and the abundant Juglandaceae and/or Tiliaceae from Le Quesnoy might have lived parasitized by scale insects. These Early Eocene parasites had an already well-established dissemination strategy, with prevalent minute first-instar larvae. The herein performed extraction technique appears well-suited for the study of carbonate coprolites and could certainly be useful for evidencing other kind of microorganisms (including internal parasites). PMID- 27689234 TI - Multimodal Imaging-Guided Antitumor Photothermal Therapy and Drug Delivery Using Bismuth Selenide Spherical Sponge. AB - Elaborately designed biocompatible nanoplatforms simultaneously having diverse therapeutic and imaging functions are highly desired for biomedical applications. Herein, a Bi2Se3 nanoagent with a special morphology as a nanoscale spherical sponge (NSS) has been fabricated and investigated in vitro and in vivo. The highly porous NSS exhibits strong, steady, and broad-band absorbance in the near infrared range as well as high efficiency and stability of photothermal conversion, resulting in high antitumor efficacy for photothermal therapy (PTT). Together with a high X-ray attenuation coefficient (218% that of the clinically used iopromide), the NSS shows excellent performance on triple-modal high contrast imaging, including X-ray-computed tomography, multispectral optoacoustic tomography, and infrared thermal imaging. Furthermore, the high surface area and porous structure impart the NSS a competent drug loading capability as high as 600% of that on Bi2Se3 nanoplates, showing a bimodal pH/photothermal sensitive drug release and pronounced synergetic effects of thermo-chemotherapy with a tumor inhibition ratio even higher than that of PTT alone (~94.4% vs ~66.0%). Meanwhile, the NSS is highly biocompatible with rather low in vitro/in vivo toxicity and high stability, at variance with easily oxidized Bi2Se3 nanoagents reported previously. Such biocompatible single-component theranostic nanoagents produced by a facile synthesis and highly integrated multimodal imaging and multiple therapeutic functions may have substantial potentials for clinical antitumor applications. This highly porous nanostructure with a large fraction of void space may allow versatile use of the NSS, for example, in catalysis, gas sensing, and energy storage, in addition to accommodating drugs and other biomolecules. PMID- 27689235 TI - One-Step Synthesis of Water-Dispersible and Biocompatible Silicon Nanoparticles for Selective Heparin Sensing and Cell Imaging. AB - A sensitive and selective fluorescence "turn-off" sensor to detect heparin using water-soluble silicon nanoparticles (Si NPs) was developed for the first time. The Si NPs were synthesized by a simple one-step procedure, which did not need high-temperature and complex modification. The as-prepared Si NPs featured strong fluorescence, favorable biocompatibility, and robust photo- and pH stability. Significantly, the Si NPs were induced to assemble or aggregate via hydrogen bonding, which resulted in the fluorescence of Si NPs quenched. Under the optimized conditions, the linear range was obtained from 0.02 to 2.0 MUg/mL, with a limit of detection of 18 ng/mL (equal to 0.004 U/mL). It was lower than the proper therapeutic level of heparin during cardiovascular surgery and long-term therapy. This proposed method was relatively free of interference from heparin analogues, which commonly existed in heparin samples and could possibly affect heparin detection. Moreover, it did not need to introduce any control medium. As expected, the method was successfully applied to detect heparin in human serum samples with satisfactory recovery ranging from 98.8 to 102.5%. The Si NPs were superbly suitable for cell imaging owing to the negligible cytotoxicity and excellent biocompatibility. PMID- 27689233 TI - An interpretative phenomenological analysis (IPA) of coercion towards community dwelling older adults with dementia: findings from Mysore studies of natal effects on ageing and health (MYNAH). AB - PURPOSE: Limited availability of specialist services places a considerable burden on caregivers of Persons with Dementia (PwD) in Low- and Middle-Income Countries (LMICs). There are limited qualitative data on coercive behavior towards PwD in an LMIC setting. AIM: The aim of this study was to find relevant themes of the lived experience of relatives as caregivers for PwD in view of their use of coercive measures in community setting in South India. METHOD: Primary caregivers (n = 13) of PwDs from the Mysore study of Natal effects on Ageing and Health (MYNAH) in South India were interviewed to explore the nature and impact of coercion towards community dwelling older adults with dementia. The narrative data were coded using an Interpretative Phenomenological Analysis (IPA) approach for thematic analysis and theory formation. RESULTS: Caregivers reported feeling physical and emotional burn-out, a lack of respite care, an absence of shared caregiving arrangements, limited knowledge of dementia, and a complete lack of community support services. They reported restrictions on their lives through not being able take employment, a poor social life, reduced income and job opportunities, and restricted movement that impacted on their physical and emotional well-being. Inappropriate use of sedatives, seclusion and environmental restraint, and restricted dietary intake, access to finances and participation in social events, was commonly reported methods of coercion used by caregivers towards PwD. Reasons given by caregivers for employing these coercive measures included safeguarding of the PwD and for the management of behavioral problems and physical health. CONCLUSION: There is an urgent need for training health and social care professionals to better understand the use of coercive measures and their impact on persons with dementia in India. It is feasible to conduct qualitative research using IPA in South India. PMID- 27689236 TI - Microfiber Masses Recovered from Conventional Machine Washing of New or Aged Garments. AB - Synthetic textiles can shed numerous microfibers during conventional washing, but evaluating environmental consequences as well as source-control strategies requires understanding mass releases. Polyester apparel accounts for a large proportion of the polyester market, and synthetic jackets represent the broadest range in apparel construction, allowing for potential changes in manufacturing as a mitigation measure to reduce microfiber release during laundering. Here, detergent-free washing experiments were conducted and replicated in both front- and top-load conventional home machines for five new and mechanically aged jackets or sweaters: four from one name-brand clothing manufacturer (three majority polyester fleece, and one nylon shell with nonwoven polyester insulation) and one off-brand (100% polyester fleece). Wash water was filtered to recover two size fractions (>333 MUm and between 20 and 333 MUm); filters were then imaged, and microfiber masses were calculated. Across all treatments, the recovered microfiber mass per garment ranged from approximately 0 to 2 g, or exceeding 0.3% of the unwashed garment mass. Microfiber masses from top-load machines were approximately 7 times those from front-load machines; garments mechanically aged via a 24 h continuous wash had increased mass release under the same wash protocol as new garments. When published wastewater treatment plant influent characterization and microfiber removal studies are considered, washing synthetic jackets or sweaters as per this study would account for most microfibers entering the environment.

AB - Treatment of (-)-sclareol and related compounds with lead tetraacetate affords tetracyclic compounds bearing a 2,8-dioxabicyclo[5.2.0]nonane moiety with complete regio- and stereoselectivity. This process, which is also applicable to 1,5-diols with a similar substitution pattern, facilitates the development of efficient syntheses toward oxepane terpenoids, such as aplysistatin derivatives. PMID- 27689237 TI - Strong Coupling of Localized Surface Plasmons to Excitons in Light-Harvesting Complexes. AB - Gold nanostructure arrays exhibit surface plasmon resonances that split after attaching light harvesting complexes 1 and 2 (LH1 and LH2) from purple bacteria. The splitting is attributed to strong coupling between the localized surface plasmon resonances and excitons in the light-harvesting complexes. Wild-type and mutant LH1 and LH2 from Rhodobacter sphaeroides containing different carotenoids yield different splitting energies, demonstrating that the coupling mechanism is sensitive to the electronic states in the light harvesting complexes. Plasmon exciton coupling models reveal different coupling strengths depending on the molecular organization and the protein coverage, consistent with strong coupling. Strong coupling was also observed for self-assembling polypeptide maquettes that contain only chlorins. However, it is not observed for monolayers of bacteriochlorophyll, indicating that strong plasmon-exciton coupling is sensitive to the specific presentation of the pigment molecules. PMID- 27689239 TI - Treatment options for hypertension in pregnancy and puerperium. AB - INTRODUCTION: Hypertensive disorders have become increasingly prevalent and complicate an increasing number of pregnancies. Therefore it is essential that the medications used to treat these disorders be well understood. Furthermore the management is complicated by special consideration needed for the physiologic changes of pregnancy as well as the consideration for possible adverse fetal effects. Areas covered: We performed a review of the scientific literature of medications used to treat hypertensive disorders in pregnancy. We reviewed the guidelines used by different societies all over the world. We also discussed the pharmacodynamics, pharmacokinetics and possible adverse effects relating to the antihypertensive medications. Finally, we discussed the long-term maternal implications of these diseases. Expert opinion: Overall, we encourage a step-wise approach to treating hypertensive disorders of pregnancy. While making sure to max out the use of one medications prior to shifting to another. Also, it is imperative not to be aggressive with treatment due to risk of compromising utero placental blood flow. There is research currently involving biomarkers, nano medicine and the placenta project with hopes of developing new targeted medications with a good fetal safety profile. PMID- 27689240 TI - Enhanced Electroreductive Removal of Bromate by a Supported Pd-In Bimetallic Catalyst: Kinetics and Mechanism Investigation. AB - In this work, the electroreductive removal of bromate by a Pd1-In4/Al2O3 catalyst in a three-dimensional electrochemical reactor was investigated. A total of 96.4% of bromate could be efficiently reduced and completely converted into bromide within 30 min under optimized conditions. On the basis of the characterization results and kinetics analysis, a synergistic effect of Pd and In was observed, and Pd1-In4/Al2O3 had the highest reaction rate constant of 0.1275 min-1 (vs 0.0413, 0.0328, and 0.0253 min-1 for In/Al2O3, Pd/Al2O3, and Al2O3). The results of electron spin resonance and scavenger experiments confirmed that both direct electron transfer and indirect reduction by atomic H* were involved in the bromate removal process, while the direct reduction played a more important role. Moreover, the introduction of In could increase the zeta potential of Pd1 In4/Al2O3, facilitating bromate adsorption and its subsequent reduction on the catalyst. Finally, a reaction mechanism for bromate reduction by Pd1-In4/Al2O3 was proposed based on all the experimental results. PMID- 27689241 TI - QTAIM-Based Characteristic Group Infrared Intensities of Amino Acids and Their Transference to Peptides. AB - Dynamic atomic contributions (DACs) to the infrared intensities of 14 amino acids have been transferred to three peptide molecules, glycylglycine, trialanine, and the melanocyte-inhibiting factor MIF-1, to estimate the infrared intensities of the most strategic peptide bands. The DACs of the amino acids and infrared intensities of the peptides were determined at the DFT B3LYP/6-311+(d,p) level. The Quantum Theory of Atoms In Molecules (QTAIM) Charge-Charge Transfer-Dipolar Polarization (CCTDP) model at this Density Functional Theory (DFT) level was used to classify the O-H, NH2, N-H, and C?O stretching as well as the NH2 bending characteristic groups for use in the transference procedure. Contrary to the frequencies, the intensities within these groups can have very diverse values, although their electronic structure changes upon vibration have predictable QTAIM behaviors for each group. Compared to the DFT calculated values, the two transferred O-H stretching intensities of the peptides are estimated with a root mean-square (rms) error of 19.1 km mol-1. Six NH2 symmetric and antisymmetric stretching intensities were determined with a 9.9 km mol-1 error. The eight estimated C?O stretching bands have a rms error of 78.0 km mol-1 or 23.6% of the average DFT peptide C?O intensity of 328.4 km mol-1. The proposed procedure is applicable to experimental infrared intensities if a calibration set of molecules with known atomic polar tensors and normal coordinate transformations is available. PMID- 27689242 TI - Latent variable modeling to analyze the effects of process parameters on the dissolution of paracetamol tablet. AB - The dissolution is one of the critical quality attributes (CQAs) of oral solid dosage forms because it relates to the absorption of drug. In this paper, the influence of raw materials, granules and process parameters on the dissolution of paracetamol tablet was analyzed using latent variable modeling methods. The variability in raw materials and granules was understood based on the principle component analysis (PCA), respectively. A multi-block partial least squares (MBPLS) model was used to determine the critical factors affecting the dissolution. The results showed that the binder amount, the post granulation time, the API content in granule, the fill depth and the punch tip separation distance were the critical factors with variable importance in the projection (VIP) values larger than 1. The importance of each unit of the whole process was also ranked using the block importance in the projection (BIP) index. It was concluded that latent variable models (LVMs) were very useful tools to extract information from the available data and improve the understanding on dissolution behavior of paracetamol tablet. The obtained LVMs were also helpful to propose the process design space and to design control strategies in the further research. PMID- 27689243 TI - Transcranial motor evoked potential waveform changes in corrective fusion for adolescent idiopathic scoliosis. AB - OBJECTIVE Corrective surgery for spinal deformities can lead to neurological complications. Several reports have described spinal cord monitoring in surgery for spinal deformity, but only a few have included patients younger than 20 years with adolescent idiopathic scoliosis (AIS). The goal of this study was to evaluate the characteristics of cases with intraoperative transcranial motor evoked potential (Tc-MEP) waveform deterioration during posterior corrective fusion for AIS. METHODS A prospective database was reviewed, comprising 68 patients with AIS who were treated with posterior corrective fusion in a prospective database. A total of 864 muscles in the lower extremities were chosen for monitoring, and acceptable baseline responses were obtained from 819 muscles (95%). Intraoperative Tc-MEP waveform deterioration was defined as a decrease in intraoperative amplitude of >= 70% of the control waveform. Age, Cobb angle, flexibility, operative time, estimated blood loss (EBL), intraoperative body temperature, blood pressure, number of levels fused, and correction rate were examined in patients with and without waveform deterioration. RESULTS The patients (3 males and 65 females) had an average age of 14.4 years (range 11-19 years). The mean Cobb angles before and after surgery were 52.9 degrees and 11.9 degrees , respectively, giving a correction rate of 77.4%. Fourteen patients (20%) exhibited an intraoperative waveform change, and these occurred during incision (14%), after screw fixation (7%), during the rotation maneuver (64%), during placement of the second rod after the rotation maneuver (7%), and after intervertebral compression (7%). Most waveform changes recovered after decreased correction or rest. No patient had a motor deficit postoperatively. In multivariate analysis, EBL (OR 1.001, p = 0.085) and number of levels fused (OR 1.535, p = 0.045) were associated with waveform deterioration. CONCLUSIONS Waveform deterioration commonly occurred during rotation maneuvers and more frequently in patients with a larger preoperative Cobb angle. The significant relationships of EBL and number of levels fused with waveform deterioration suggest that these surgical invasions may be involved in waveform deterioration. PMID- 27689244 TI - Clinical predictors of vestibulo-ocular dysfunction in pediatric sports-related concussion. AB - OBJECTIVE There were 2 objectives of this study. The first objective was to identify clinical variables associated with vestibulo-ocular dysfunction (VOD) detected at initial consultation among pediatric patients with acute sports related concussion (SRC) and postconcussion syndrome (PCS). The second objective was to reexamine the prevalence of VOD in this clinical cohort and evaluate the effect of VOD on length of recovery and the development of PCS. METHODS A retrospective review was conducted for all patients with acute SRC and PCS who were evaluated at a pediatric multidisciplinary concussion program from September 2013 to May 2015. Acute SRS was defined as presenting < 30 days postinjury, and PCS was defined according to the International Classification of Diseases, 10th Revision criteria and included being symptomatic 30 days or longer postinjury. The initial assessment included clinical history and physical examination performed by 1 neurosurgeon. Patients were assessed for VOD, defined as the presence of more than 1 subjective vestibular and oculomotor complaint (dizziness, diplopia, blurred vision, etc.) and more than 1 objective physical examination finding (abnormal near point of convergence, smooth pursuits, saccades, or vestibulo-ocular reflex testing). Poisson regression analysis was used to identify factors that increased the risk of VOD at initial presentation and the development of PCS. RESULTS Three hundred ninety-nine children, including 306 patients with acute SRC and 93 with PCS, were included. Of these patients, 30.1% of those with acute SRC (65.0% male, mean age 13.9 years) and 43.0% of those with PCS (41.9% male, mean age 15.4 years) met the criteria for VOD at initial consultation. Independent predictors of VOD at initial consultation included female sex, preinjury history of depression, posttraumatic amnesia, and presence of dizziness, blurred vision, or difficulty focusing at the time of injury. Independent predictors of PCS among patients with acute SRC included the presence of VOD at initial consultation, preinjury history of depression, and posttraumatic amnesia at the time of injury. CONCLUSIONS This study identified important potential risk factors for the development of VOD following pediatric SRC. These results provide confirmatory evidence that VOD at initial consultation is associated with prolonged recovery and is an independent predictor for the development of PCS. Future studies examining clinical prediction rules in pediatric concussion should include VOD. Additional research is needed to elucidate the natural history of VOD following SRC and establish evidence-based indications for targeted vestibular rehabilitation. PMID- 27689245 TI - Vessel-preserving stent-assisted coil embolization of an extracranial internal carotid artery pseudoaneurysm that developed after tonsillectomy in a pediatric patient: initial case report. AB - Although there have been reports of carotid artery pseudoaneurysm formation after adenoidectomy and/or tonsillectomy secondary to iatrogenic injury, there are no case reports of successful endovascular reconstruction of the injured artery in the pediatric population. In most pediatric cases, the internal carotid artery (ICA) is sacrificed. The authors report on a 6-year-old girl who presented with odynophagia, left-sided Horner's syndrome, hematemesis, and severe anemia 6 months after a tonsillectomy. On examination she was found to have a pulsatile mass along the left posterior lateral oropharynx, and imaging demonstrated a dissection of the extracranial left ICA and an associated pseudoaneurysm. The lesion was managed endovascularly with stent-assisted coil embolization and ICA reconstruction. The child had a somewhat complicated postoperative course, requiring additional coil embolization for treatment of a minor recurrence of the pseudoaneurysm at 5 months after the initial treatment and then presenting with extrusion of a portion of the coil mass into the oropharyngeal cavity a year later. She underwent surgical removal of the extruded coils and repair of the defect and has since been free of symptoms or signs of recurrence. The authors conclude that this strategy definitively protected the patient against an oral exsanguination or aspiration event secondary to aneurysm rupture and reduced her risk of stroke by preserving vessel patency and caliber. Moreover, they note that covered stent reconstruction surrenders endovascular access and cannot immediately provide these benefits.

AB - Neurofibrosarcoma is rare in the pediatric age group. A malignant tumor of the sacrum presents significant challenges, especially if the goals are to resect with wide and clean surgical margins and to achieve acceptable functional outcomes. The authors report a case of this rare tumor affecting the sacrum and sacral nerve roots of a 7-year-old girl and review the role of total hemisacrectomy sparing the contralateral sacral nerve roots and lumbopelvic reconstruction in the treatment of this disease. This patient is, to the best of the authors' knowledge, the youngest to be treated in this manner. PMID- 27689248 TI - Trends and Predictors of Limb Tourniquet Use by Civilian Emergency Medical Services in the United States. AB - BACKGROUND: Tourniquet use by Emergency Medical Services (EMS) can be life saving for severely injured patients. The adoption of this intervention is not well described in civilian settings. This study describes patterns and trends of tourniquet use by civilian EMS and identifies predictors of such use. METHODS: A retrospective study of four consecutive releases of the U.S. National Emergency Medical Services Information System (NEMSIS) public research dataset (2011-14) was conducted. Descriptive analysis was performed to compare two groups of EMS activations for injuries with or without tourniquet application. This was followed by multivariate logistic regression to identify predictors of tourniquet use. RESULTS: A total of 2,048 tourniquet applications were documented among all EMS activations for injured patients (N = 10,366,537) yielding a prevalence of 0.2 per 1,000 EMS activations. Tourniquets were mainly applied in young (mean age 44.0 +/- 21.1 years) male patients (76.5%) in urban and suburban EMS activations (86.4%) and by advanced life support (ALS) EMS services (81.6%). Most common complaints reported by dispatch for EMS activations with tourniquet use were Traumatic injury (25.3%), Hemorrhage/laceration (23.5%), and Traffic accident (16.8%) with injuries mainly related to Stabbing/Accidental cutting (20.3%), Falls (17.1%), and Motor vehicle traffic accident (11.5%). Upper extremity injuries (39.6%) were more common than Lower extremity injuries (27.3%). The providers' primary impression was predominantly Traumatic injury (92.8%), and patients' primary symptoms were mainly Bleeding (50.4%) and Wound (28.7%). All prehospital time intervals except on-scene time interval were significantly shorter in the group with tourniquets compared to the group without tourniquets (p < 0.05). Reported prevalence of tourniquet use by EMS (per 1,000 EMS injury activations) increased from 2011 to 2012 then stabilized over the following years (2012-14). Significant predictors of tourniquet use reported by the provider were identified and included demographic characteristics, EMS agency type, specific complaints, injury cause, injury anatomic location, chief complaint organ system, and primary symptom. CONCLUSION: Reported tourniquet use by EMS for injured patients in the U.S. is low. Increasing adoption mainly by urban services was noted. Predictors for tourniquet use in civilian trauma were identified. Establishing the effectiveness of this intervention by comparing patient outcomes is needed. Key words: emergency medical services; prehospital; tourniquet; injury; NEMSIS; hemorrhage.

PMID- 27689250 TI - Subclinical Thyroid Dysfunction and the Risk of Cognitive Decline: a Meta Analysis of Prospective Cohort Studies. AB - CONTEXT: Although both overt hyper- and hypothyroidism are known to lead to cognitive impairment, data on the association between subclinical thyroid dysfunction and cognitive function are conflicting. OBJECTIVE: This study sought to determine the risk of dementia and cognitive decline associated with subclinical thyroid dysfunction among prospective cohorts. DATA SOURCES: We searched in MEDLINE and EMBASE from inception until November 2014. STUDY SELECTION: Two physicians identified prospective cohorts that assessed thyroid function and cognitive outcomes (dementia; Mini-Mental State Examination [MMSE]). DATA EXTRACTION: Data were extracted by one reviewer following standardized protocols and verified by a second reviewer. The primary outcome was dementia and decline in cognitive function was the secondary outcome. DATA SYNTHESIS: Eleven prospective cohorts followed 16,805 participants during a median followup of 44.4 months. Five studies analyzed the risk of dementia in subclinical hyperthyroidism (SHyper) (n = 6410), six in subclinical hypothyroidism (SHypo) (n = 7401). Five studies analyzed MMSE decline in SHyper (n = 7895), seven in SHypo (n = 8960). In random-effects models, the pooled adjusted risk ratio for dementia in SHyper was 1.67 (95% confidence interval, 1.04; 2.69) and 1.14 (95% confidence interval, 0.84; 1.55) in SHypo vs euthyroidism, both without evidence of significant heterogeneity (I2 = 0.0%). The pooled mean MMSE decline from baseline to followup (mean 32 mo) did not significantly differ between SHyper or SHypo vs euthyroidism. CONCLUSIONS: SHyper might be associated with an elevated risk for dementia, whereas SHypo is not, and both conditions are not associated with faster decline in MMSE over time. Available data are limited, and additional large, high-quality studies are needed. PMID- 27689251 TI - miR-146a, miR-155, miR-370, and miR-708 Are CFTR-Dependent, Predicted FOXO1 Regulators and Change at Onset of CFRDs. AB - CONTEXT: Cystic fibrosis-related diabetes (CFRD) is the most frequent and severe co-morbidity in cystic fibrosis (CF). Presentation and severity are quite variable. OBJECTIVE: To investigate changes in microRNAs (miRNAs) due to CF transmembrane conductance regulator malfunctioning in vitro, to study the circulating levels of selected miRNAs in serum samples from patients, and to assess their relationships in different age groups with genotype, glucose tolerance state, and at onset of CFRD. Design/Setting/Patients/Interventions: Transcriptional profiling of all known miRNAs in CFBE41o- cells, in their normal counterparts (16HBE14o- cells), and in IB3 cells was performed. A set of miRNAs was differentially expressed in the CF cells. By in silico analysis, four miRNAs (miR-146a, miR-155, miR-370, and miR-708) were selected as potential regulators of the FOXO1 gene. Seventy-four CF patients and 50 healthy subjects whose glucose tolerance was characterized by an oral glucose tolerance test were enrolled in the study, and the identified miRNAs were quantified in serum by quantitative RT PCR. Main Outcome Measurements/Results: A total of 111 miRNAs were differentially expressed in the two CF cell lines. miR-155, miR-370, and miR-708 were up regulated and miR-146a was down-regulated in vitro, whereas in vivo, miR-146a, miR-155, and miR-370 were up-regulated, and miR-708 was down-regulated. These changes showed relationships with genotype, glucose tolerance state, and onset of CFRD. CONCLUSIONS: The data showed significant changes in miRNAs dependent on genotype and glucose tolerance state in CF patients and highlighted some miRNAs of importance in CFRD at onset. miRNAs could explain some of the variability observed in CF. PMID- 27689252 TI - Clinical, Sonographic, and Pathological Characteristics of RAS-Positive Versus BRAF-Positive Thyroid Carcinoma. AB - CONTEXT: Mutations in the BRAF and RAS oncogenes are responsible for most well differentiated thyroid cancer. Yet, our clinical understanding of how BRAF positive and RAS-positive thyroid cancers differ is incomplete. OBJECTIVE: We correlated clinical, radiographic, and pathological findings from patients with thyroid cancer harboring a BRAF or RAS mutation. DESIGN: Prospective cohort study. SETTING: Academic, tertiary care hospital. PATIENTS: A total of 101 consecutive patients with well-differentiated thyroid cancer. MAIN OUTCOME MEASURE: We compared the clinical, sonographic, and pathological characteristics of patients with BRAF-positive cancer to those with RAS-positive cancer. RESULTS: Of 101 patients harboring these mutations, 71 were BRAF-positive, whereas 30 were RAS-positive. Upon sonographic evaluation, RAS-positive nodules were significantly larger (P = .04), although BRAF-positive nodules were more likely to harbor concerning sonographic characteristics (hypoechogenicity [P < .001]; irregular margins [P = .04]). Cytologically, 70% of BRAF-positive nodules were classified positive for PTC, whereas 87% of RAS-positive nodules were indeterminate (P < .001). Histologically, 96% of RAS-positive PTC malignancies were follicular variants of PTC, whereas 70% of BRAF-positive malignancies were classical variants of PTC. BRAF-positive malignancies were more likely to demonstrate extrathyroidal extension (P = .003), lymphovascular invasion (P = .02), and lymph node metastasis (P < .001). CONCLUSIONS: BRAF-positive malignant nodules most often demonstrate worrisome sonographic features and are frequently associated with positive or suspicious Bethesda cytology. In contrast, RAS positive malignancy most often demonstrates indolent sonographic features and more commonly associates with lower risk, "indeterminate" cytology. Because BRAF and RAS mutations are the most common molecular perturbations associated with well-differentiated thyroid cancer, these findings may assist with improved preoperative risk assessment by suggesting the likely molecular profile of a thyroid cancer, even when postsurgical molecular analysis is unavailable. PMID- 27689254 TI - Doctors' recognition and management of melanoma patients' risk: An Australian population-based study. AB - BACKGROUND: Guidelines recommend that health professionals identify and manage individuals at high risk of developing melanoma, but there is limited population based evidence demonstrating real-world practices. OBJECTIVE: A population-based, observational study was conducted in the state of New South Wales, Australia to determine doctors' knowledge of melanoma patients' risk and to identify factors associated with better identification and clinical management. METHODS: Data were analysed for 1889 patients with invasive, localised melanoma in the Melanoma Patterns of Care study. This study collected data on all melanoma diagnoses notified to the state's cancer registry during a 12-month period from 2006 to 2007, as well as questionnaire data from the doctors involved in their care. RESULTS: Three-quarters (74%) of patients had doctors who were aware of their risk factor status with respect to personal and family history of melanoma and the presence of many moles. Doctors working in general practice, skin cancer clinics and dermatology settings had better knowledge of patients' risk factors than plastic surgeons. Doctors were 15% more likely to know the family history of younger melanoma patients (<40years) than of those >=80 years (95% confidence interval 4-26%). Early detection-related follow-up advice was more likely to be given to younger patients, by doctors aware of their patients' risk status, by doctors practising in plastic surgery, dermatology and skin cancer clinic settings, and by female doctors. CONCLUSION: Both patient-related and doctor related factors were associated with doctors' recognition and management of melanoma patients' risk and could be the focus of strategies for improving care. PMID- 27689255 TI - Direct Measurement of the Density Matrix of a Quantum System. AB - One drawback of conventional quantum state tomography is that it does not readily provide access to single density matrix elements since it requires a global reconstruction. Here, we experimentally demonstrate a scheme that can be used to directly measure individual density matrix elements of general quantum states. The scheme relies on measuring a sequence of three observables, each complementary to the last. The first two measurements are made weak to minimize the disturbance they cause to the state, while the final measurement is strong. We perform this joint measurement on polarized photons in pure and mixed states to directly measure their density matrix. The weak measurements are achieved using two walk-off crystals, each inducing a polarization-dependent spatial shift that couples the spatial and polarization degrees of freedom of the photons. This direct measurement method provides an operational meaning to the density matrix and promises to be especially useful for large dimensional states.

AB - AIMS: Pro- and anti-inflammatory cytokines play a significant role in early atherosclerosis. Linkage disequilibrium patterns differ between ethnic groups pointing toward the need to develop population-specific gene risk scores. Our objective was to investigate the role of a cytokine gene score in the risk prediction of premature coronary artery disease (PCAD). METHODS: A case-control study was performed at the National University of Sciences and Technology (NUST) in collaboration with the Cardiovascular Genetics Institute, University College London, United Kingdom. Three hundred forty subjects with >70% stenosis in at least one coronary vessel on angiography were labeled as PCAD cases and compared with 310 angio-negative controls. Genotyping of the rs187238 (interleukin [IL] 18), rs1800795 (IL-6), rs1800629 (tumor necrosis factor [TNF]-alpha), rs1800871 (IL-10), and rs1946519 (IL-18) SNPs was performed using KASPar and TaqMan assays. RESULTS: The odds ratio for cytokine gene score was significantly higher for PCAD (p = 0.025) when adjusted for age, sex, and ethnicity. There was a highly significant difference in gene risk allele frequency between Pakistanis and Caucasians (Northwick Park Heart Study II [NPHSII]) for rs187238 (IL-18), rs1800795 (IL-6), rs1800629 (TNF-alpha), and rs1800871 (IL-10) (p < 0.01). CONCLUSIONS: A cytokine gene score has significant discriminatory ability and potential in the risk prediction of PCAD. Cytokine gene risk allele frequencies differ significantly between Pakistanis and Caucasians supporting the need to develop population-specific gene scores. PMID- 27689256 TI - Accessing Many-Body Localized States through the Generalized Gibbs Ensemble. AB - We show how the thermodynamic properties of large many-body localized systems can be studied using quantum Monte Carlo simulations. We devise a heuristic way of constructing local integrals of motion of high quality, which are added to the Hamiltonian in conjunction with Lagrange multipliers. The ground state simulation of the shifted Hamiltonian corresponds to a high-energy state of the original Hamiltonian in the case of exactly known local integrals of motion. The inevitable mixing between eigenstates as a consequence of nonperfect integrals of motion is weak enough such that the characteristics of many-body localized systems are not averaged out, unlike the standard ensembles of statistical mechanics. Our method paves the way to study higher dimensions and indicates that a fully many-body localized phase in 2D, where (nearly) all eigenstates are localized, is likely to exist. PMID- 27689257 TI - Noise Threshold and Resource Cost of Fault-Tolerant Quantum Computing with Majorana Fermions in Hybrid Systems. AB - Fault-tolerant quantum computing in systems composed of both Majorana fermions and topologically unprotected quantum systems, e.g., superconducting circuits or quantum dots, is studied in this Letter. Errors caused by topologically unprotected quantum systems need to be corrected with error-correction schemes, for instance, the surface code. We find that the error-correction performance of such a hybrid topological quantum computer is not superior to a normal quantum computer unless the topological charge of Majorana fermions is insusceptible to noise. If errors changing the topological charge are rare, the fault-tolerance threshold is much higher than the threshold of a normal quantum computer and a surface-code logical qubit could be encoded in only tens of topological qubits instead of about 1,000 normal qubits. PMID- 27689258 TI - Quasiprobability Representations of Quantum Mechanics with Minimal Negativity. AB - Quasiprobability representations, such as the Wigner function, play an important role in various research areas. The inevitable appearance of negativity in such representations is often regarded as a signature of nonclassicality, which has profound implications for quantum computation. However, little is known about the minimal negativity that is necessary in general quasiprobability representations. Here we focus on a natural class of quasiprobability representations that is distinguished by simplicity and economy. We introduce three measures of negativity concerning the representations of quantum states, unitary transformations, and quantum channels, respectively. Quite surprisingly, all three measures lead to the same representations with minimal negativity, which are in one-to-one correspondence with the elusive symmetric informationally complete measurements. In addition, most representations with minimal negativity are automatically covariant with respect to the Heisenberg-Weyl groups. Furthermore, our study reveals an interesting tradeoff between negativity and symmetry in quasiprobability representations. PMID- 27689259 TI - Grover Search and the No-Signaling Principle. AB - Two of the key properties of quantum physics are the no-signaling principle and the Grover search lower bound. That is, despite admitting stronger-than-classical correlations, quantum mechanics does not imply superluminal signaling, and despite a form of exponential parallelism, quantum mechanics does not imply polynomial-time brute force solution of NP-complete problems. Here, we investigate the degree to which these two properties are connected. We examine four classes of deviations from quantum mechanics, for which we draw inspiration from the literature on the black hole information paradox. We show that in these models, the physical resources required to send a superluminal signal scale polynomially with the resources needed to speed up Grover's algorithm. Hence the no-signaling principle is equivalent to the inability to solve NP-hard problems efficiently by brute force within the classes of theories analyzed. PMID- 27689260 TI - Observation of Noise Correlated by the Hawking Effect in a Water Tank. AB - We measured the power spectrum and two-point correlation function for the randomly fluctuating free surface on the downstream side of a stationary flow with a maximum Froude number F_{max}~0.85 reached above a localized obstacle. On such a flow the scattering of incident long wavelength modes is analogous to that responsible for black hole radiation (the Hawking effect). Our measurements of the noise show a clear correlation between pairs of modes of opposite energies. We also measure the scattering coefficients by applying the same analysis of correlations to waves produced by a wave maker. PMID- 27689261 TI - Detectability of Light Dark Matter with Superfluid Helium. AB - We show that a two-excitation process in superfluid helium, combined with sensitivity to meV energy depositions, can probe dark matter down to the ~keV warm dark matter mass limit. This mass reach is 3 orders of magnitude below what can be probed with ordinary nuclear recoils in helium at the same energy resolution. For dark matter lighter than ~100 keV, the kinematics of the process requires the two athermal excitations to have nearly equal and opposite momentum, potentially providing a built-in coincidence mechanism for controlling backgrounds. PMID- 27689263 TI - Classically Stable Nonsingular Cosmological Bounces. AB - One of the fundamental questions of theoretical cosmology is whether the Universe can undergo a nonsingular bounce, i.e., smoothly transit from a period of contraction to a period of expansion through violation of the null energy condition (NEC) at energies well below the Planck scale and at finite values of the scale factor such that the entire evolution remains classical. A common claim has been that a nonsingular bounce either leads to ghost or gradient instabilities or a cosmological singularity. In this Letter, we consider a well motivated class of theories based on the cubic Galileon action and present a procedure for explicitly constructing examples of a nonsingular cosmological bounce without encountering any pathologies and maintaining a subluminal sound speed for comoving curvature modes throughout the NEC violating phase. We also discuss the relation between our procedure and earlier work. PMID- 27689264 TI - Matrix Product Approximations to Multipoint Functions in Two-Dimensional Conformal Field Theory. AB - Matrix product states (MPSs) illustrate the suitability of tensor networks for the description of interacting many-body systems: ground states of gapped 1D systems are approximable by MPSs, as shown by Hastings [M. B. Hastings, J. Stat. Mech. (2007) P08024]. By contrast, whether MPSs and more general tensor networks can accurately reproduce correlations in critical quantum systems or quantum field theories has not been established rigorously. Ample evidence exists: entropic considerations provide restrictions on the form of suitable ansatz states, and numerical studies show that certain tensor networks can indeed approximate the associated correlation functions. Here, we provide a complete positive answer to this question in the case of MPSs and 2D conformal field theory: we give quantitative estimates for the approximation error when approximating correlation functions by MPSs. Our work is constructive and yields an explicit MPS, thus providing both suitable initial values and a rigorous justification of variational methods. PMID- 27689265 TI - Dense Axion Stars. AB - If the dark matter particles are axions, gravity can cause them to coalesce into axion stars, which are stable gravitationally bound systems of axions. In the previously known solutions for axion stars, gravity and the attractive force between pairs of axions are balanced by the kinetic pressure. The mass of these dilute axion stars cannot exceed a critical mass, which is about 10^{-14}M_{?} if the axion mass is 10^{-4} eV. We study axion stars using a simple approximation to the effective potential of the nonrelativistic effective field theory for axions. We find a new branch of dense axion stars in which gravity is balanced by the mean-field pressure of the axion Bose-Einstein condensate. The mass on this branch ranges from about 10^{-20}M_{?} to about M_{?}. If a dilute axion star with the critical mass accretes additional axions and collapses, it could produce a bosenova, leaving a dense axion star as the remnant. PMID- 27689266 TI - Two-Flavor Simulations of rho(770) and the Role of the KK[over -] Channel. AB - The rho(770) meson is the most extensively studied resonance in lattice QCD simulations in two (N_{f}=2) and three (N_{f}=2+1) flavor formulations. We analyze N_{f}=2 lattice scattering data using unitarized chiral perturbation theory, allowing not only for the extrapolation in mass but also in flavor, N_{f}=2->N_{f}=2+1. The flavor extrapolation requires information from a global fit to pipi and piK phase shifts from experiment. While the chiral extrapolation of N_{f}=2 lattice data leads to masses of the rho(770) meson far below the experimental one, we find that the missing KK[over -] channel is able to explain this discrepancy. PMID- 27689267 TI - Formation of CN^{-}, C_{3}N^{-}, and C_{5}N^{-} Molecules by Radiative Electron Attachment and their Destruction by Photodetachment. AB - The existence of negative ions in interstellar clouds has been associated for several decades with the process of radiative electron attachment. In this Letter, we report compelling evidence supporting the fact that the radiative attachment of a low-energy electron is inefficient to form the carbon chain anions CN^{-}, C_{3}N^{-}, and C_{5}N^{-} detected in interstellar clouds. The validity of the approach is confirmed by good agreement with experimental data obtained for the inverse photodetachment process, which represents the major cause of anion destruction in interstellar space. As a consequence, we suggest alternative models that could explain the formation of anions. PMID- 27689262 TI - Dark Matter Results from First 98.7 Days of Data from the PandaX-II Experiment. AB - We report the weakly interacting massive particle (WIMP) dark matter search results using the first physics-run data of the PandaX-II 500 kg liquid xenon dual-phase time-projection chamber, operating at the China JinPing underground laboratory. No dark matter candidate is identified above background. In combination with the data set during the commissioning run, with a total exposure of 3.3*10^{4} kg day, the most stringent limit to the spin-independent interaction between the ordinary and WIMP dark matter is set for a range of dark matter mass between 5 and 1000 GeV/c^{2}. The best upper limit on the scattering cross section is found 2.5*10^{-46} cm^{2} for the WIMP mass 40 GeV/c^{2} at 90% confidence level. PMID- 27689268 TI - Rydberg Molecule-Induced Remote Spin Flips. AB - We have performed high resolution photoassociation spectroscopy of rubidium ultralong-range Rydberg molecules in the vicinity of the 25P state. Because of the hyperfine interaction in the ground state perturber atom, the emerging mixed singlet-triplet potentials contain contributions from both hyperfine states. We show that this can be used to induce remote spin flips in the perturber atom upon excitation of a Rydberg molecule. Furthermore, when the spin-orbit splitting of the Rydberg state is comparable to the hyperfine splitting in the ground state, the orbital angular momentum of the Rydberg electron is entangled with the nuclear spin of the perturber atom. Our results open new possibilities for the implementation of spin-dependent interactions for ultracold atoms in bulk systems and in optical lattices. PMID- 27689269 TI - Coherence Preservation of a Single Neutral Atom Qubit Transferred between Magic Intensity Optical Traps. AB - We demonstrate that the coherence of a single mobile atomic qubit can be well preserved during a transfer process among different optical dipole traps (ODTs). This is a prerequisite step in realizing a large-scale neutral atom quantum information processing platform. A qubit encoded in the hyperfine manifold of an ^{87}Rb atom is dynamically extracted from the static quantum register by an auxiliary moving ODT and reinserted into the static ODT. Previous experiments were limited by decoherences induced by the differential light shifts of qubit states. Here, we apply a magic-intensity trapping technique which mitigates the detrimental effects of light shifts and substantially enhances the coherence time to 225+/-21 ms. The experimentally demonstrated magic trapping technique relies on the previously neglected hyperpolarizability contribution to the light shifts, which makes the light shift dependence on the trapping laser intensity parabolic. Because of the parabolic dependence, at a certain "magic" intensity, the first order sensitivity to trapping light-intensity variations over ODT volume is eliminated. We experimentally demonstrate the utility of this approach and measure hyperpolarizability for the first time. Our results pave the way for constructing scalable quantum-computing architectures with single atoms trapped in an array of magic ODTs. PMID- 27689271 TI - Quantum Phase Transition in the Finite Jaynes-Cummings Lattice Systems. AB - Phase transitions are commonly held to occur only in the thermodynamical limit of a large number of system components. Here, we exemplify at the hand of the exactly solvable Jaynes-Cummings (JC) model and its generalization to finite JC lattices that finite component systems of coupled spins and bosons may exhibit quantum phase transitions (QPTs). For the JC model we find a continuous symmetry breaking QPT, a photonic condensate with a macroscopic occupation as the ground state, and a Goldstone mode as a low-energy excitation. For the two site JC lattice we show analytically that it undergoes a Mott-insulator to superfluid QPT. We identify as the underlying principle of the emergence of finite system QPTs the combination of increasing atomic energy and increasing interaction strength between the atom and the bosonic mode, which allows for the exploration of an increasingly large portion of the infinite dimensional Hilbert space of the bosonic mode. This suggests that finite system phase transitions will be present in a broad range of physical systems. PMID- 27689270 TI - Observation of Parity-Time Symmetry in Optically Induced Atomic Lattices. AB - We experimentally demonstrate PT-symmetric optical lattices with periodical gain and loss profiles in a coherently prepared four-level N-type atomic system. By appropriately tuning the pertinent atomic parameters, the onset of PT-symmetry breaking is observed through measuring an abrupt phase-shift jump between adjacent gain and loss waveguides. The experimental realization of such a readily reconfigurable and effectively controllable PT-symmetric waveguide array structure sets a new stage for further exploiting and better understanding the peculiar physical properties of these non-Hermitian systems in atomic settings. PMID- 27689272 TI - Multimode Strong Coupling in Superconducting Cavity Piezoelectromechanics. AB - High-frequency mechanical resonators subjected to low thermal phonon occupancy are easier to be prepared to the ground state by direct cryogenic cooling. Their extreme stiffness, however, poses a significant challenge for external interrogations. Here we demonstrate a superconducting cavity piezoelectromechanical system in which multiple modes of a bulk acoustic resonator oscillating at 10 GHz are coupled to a planar microwave superconducting resonator with a cooperativity exceeding 2*10^{3}, deep in the strong coupling regime. By implementation of the noncontact coupling scheme to reduce mechanical dissipation, the system exhibits excellent coherence characterized by a frequency quality-factor product of 7.5*10^{15} Hz. Interesting dynamics of classical temporal oscillations of the microwave energy is observed, implying the coherent conversion between phonons and photons. The demonstrated high-frequency cavity piezoelectromechanics is compatible with superconducting qubits, representing an important step towards hybrid quantum systems. PMID- 27689273 TI - Torsional Optomechanics of a Levitated Nonspherical Nanoparticle. AB - An optically levitated nanoparticle in vacuum is a paradigm optomechanical system for sensing and studying macroscopic quantum mechanics. While its center-of-mass motion has been investigated intensively, its torsional vibration has only been studied theoretically in limited cases. Here we report the first experimental observation of the torsional vibration of an optically levitated nonspherical nanoparticle in vacuum. We achieve this by utilizing the coupling between the spin angular momentum of photons and the torsional vibration of a nonspherical nanoparticle whose polarizability is a tensor. The torsional vibration frequency can be 1 order of magnitude higher than its center-of-mass motion frequency, which is promising for ground state cooling. We propose a simple yet novel scheme to achieve ground state cooling of its torsional vibration with a linearly polarized Gaussian cavity mode. A levitated nonspherical nanoparticle in vacuum will also be an ultrasensitive nanoscale torsion balance with a torque detection sensitivity on the order of 10^{-29} N m/sqrt[Hz] under realistic conditions. PMID- 27689274 TI - Optomagnonic Whispering Gallery Microresonators. AB - Magnons in ferrimagnetic insulators such as yttrium iron garnet (YIG) have recently emerged as promising candidates for coherent information processing in microwave circuits. Here we demonstrate optical whispering gallery modes of a YIG sphere interrogated by a silicon nitride photonic waveguide, with quality factors approaching 10^{6} in the telecom c band after surface treatments. Moreover, in contrast to conventional Faraday setups, this implement allows an input photon polarized colinearly to the magnetization to be scattered to a sideband mode of orthogonal polarization. This Brillouin scattering process is enhanced through triply resonant magnon, pump, and signal photon modes within an "optomagnonic cavity." Our results show the potential use of magnons for mediating microwave-to optical carrier conversion. PMID- 27689275 TI - Generation of Photon-Plasmon Quantum States in Nonlinear Hyperbolic Metamaterials. AB - We develop a general theoretical framework of integrated paired photon-plasmon generation through spontaneous wave mixing in nonlinear plasmonic and metamaterial nanostructures, rigorously accounting for material dispersion and losses in the quantum regime through the electromagnetic Green function. We identify photon-plasmon correlations in layered metal-dielectric structures with 70% internal heralding quantum efficiency and reveal a novel mechanism of broadband generation enhancement due to topological transition in hyperbolic metamaterials. PMID- 27689276 TI - On-Chip Strong Coupling and Efficient Frequency Conversion between Telecom and Visible Optical Modes. AB - While the frequency conversion of photons has been realized with various approaches, the realization of strong coupling between optical modes of different colors has never been reported. Here, we present an experimental demonstration of strong coupling between telecom (1550 nm) and visible (775 nm) optical modes on an aluminum nitride photonic chip. The nonreciprocal normal-mode splitting is demonstrated as a result of the coherent interference between photons with different colors. Furthermore, a wideband, bidirectional frequency conversion with 0.14 on-chip conversion efficiency and a bandwidth up to 1.2 GHz is demonstrated. PMID- 27689277 TI - Compton Scattered X-Gamma Rays with Orbital Momentum. AB - We study the possibility of producing x-gamma rays with orbital angular momentum by means of the inverse Compton backscattering between a high brightness electron beam and a twisted laser pulse. We use the classical electrodynamics retarded fields for evaluating the orbital angular momentum of the radiation and connecting it to that of the primary laser pulse. We then propose the dimensioning of a linearly polarized x-ray source with orbital angular momentum, starting from the parameters of operating Thomson setups. PMID- 27689278 TI - Nonlinear Plasmonic Sensing with Nanographene. AB - Plasmons provide excellent sensitivity to detect analyte molecules through their strong interaction with the dielectric environment. Plasmonic sensors based on noble metals are, however, limited by the spectral broadening of these excitations. Here we identify a new mechanism that reveals the presence of individual molecules through the radical changes that they produce in the plasmons of graphene nanoislands. An elementary charge or a weak permanent dipole carried by the molecule are shown to be sufficient to trigger observable modifications in the linear absorption spectra and the nonlinear response of the nanoislands. In particular, a strong second-harmonic signal, forbidden by symmetry in the unexposed graphene nanostructure, emerges due to a redistribution of conduction electrons produced by interaction with the molecule. These results pave the way toward ultrasensitive nonlinear detection of dipolar molecules and molecular radicals that is made possible by the extraordinary optoelectronic properties of graphene. PMID- 27689279 TI - Internal Stresses Lead to Net Forces and Torques on Extended Elastic Bodies. AB - A geometrically frustrated elastic body will develop residual stresses arising from the mismatch between the intrinsic geometry of the body and the geometry of the ambient space. We analyze these stresses for an ambient space with gradients in its intrinsic curvature, and show that residual stresses generate effective forces and torques on the center of mass of the body. We analytically calculate these forces in two dimensions, and experimentally demonstrate their action by the migration of a non-Euclidean gel disc in a curved Hele-Shaw cell. An extension of our analysis to higher dimensions shows that these forces are also generated in three dimensions, but are negligible compared to gravity. PMID- 27689280 TI - High-Brightness High-Energy Electron Beams from a Laser Wakefield Accelerator via Energy Chirp Control. AB - By designing a structured gas density profile between the dual-stage gas jets to manipulate electron seeding and energy chirp reversal for compressing the energy spread, we have experimentally produced high-brightness high-energy electron beams from a cascaded laser wakefield accelerator with peak energies in the range of 200-600 MeV, 0.4%-1.2% rms energy spread, 10-80 pC charge, and ~0.2 mrad rms divergence. The maximum six-dimensional brightness B_{6D,n} is estimated as ~6.5*10^{15} A/m^{2}/0.1%, which is very close to the typical brightness of e beams from state-of-the-art linac drivers. These high-brightness high-energy e beams may lead to the realization of compact monoenergetic gamma-ray and intense coherent x-ray radiation sources. PMID- 27689281 TI - Waveform-Controlled Relativistic High-Order-Harmonic Generation. AB - We consider the efficiency limit of relativistic high-order-harmonic emission from solid targets achievable with tailored light fields. Using one-dimensional particle-in-cell simulations, the maximum energy conversion efficiency is shown to reach as high as 10% for the harmonics in the range of 80-200 eV and is largely independent of laser intensity and plasma density. The waveforms most effective at driving harmonics have a broad spectrum with a lower-frequency limit set by the width of the incident pulse envelope and an upper limit set by the relativistic plasma frequency.

The model predicts the probability distribution function of the flow strength as well as the evolution of the characteristic spatial scale. Magnetic toroidicity-induced global phase dynamics is shown to determine the spatial structure of the flow. A key result is the observation that global phase patterning can lead to zonal flow formation in the absence of turbulence inhomogeneity.

AB - We study the zero-temperature phase diagram of a spin-orbit-coupled Bose-Einstein condensate of spin 1, with equally weighted Rashba and Dresselhaus couplings. Depending on the antiferromagnetic or ferromagnetic nature of the interactions, we find three kinds of striped phases with qualitatively different behaviors in the modulations of the density profiles. Phase transitions to the zero-momentum and the plane-wave phases can be induced in experiments by independently varying the Raman coupling strength and the quadratic Zeeman field. The properties of these transitions are investigated in detail, and the emergence of tricritical points, which are the direct consequence of the spin-dependent interactions, is explicitly discussed. PMID- 27689284 TI - Tuning the Fabrication of Nanostructures by Low-Energy Highly Charged Ions. AB - Slow highly charged ions have been utilized recently for the creation of monotype surface nanostructures (craters, calderas, or hillocks) in different materials. In the present study, we report on the ability of slow highly charged xenon ions (^{129}Xe^{Q+}) to form three different types of nanostructures on the LiF(100) surface. By increasing the charge state from Q=15 to Q=36, the shape of the impact induced nanostructures changes from craters to hillocks crossing an intermediate stage of caldera structures. A dimensional analysis of the nanostructures reveals an increase of the height up to 1.5 nm as a function of the potential energy of the incident ions. Based on the evolution of both the geometry and size of the created nanostructures, defect-mediated desorption and the development of a thermal spike are utilized as creation mechanisms of the nanostructures at low and high charge states, respectively. PMID- 27689285 TI - Giant Rashba Splitting in CH_{3}NH_{3}PbBr_{3} Organic-Inorganic Perovskite. AB - As they combine decent mobilities with extremely long carrier lifetimes, organic inorganic perovskites open a whole new field in optoelectronics. Measurements of their underlying electronic structure, however, are still lacking. Using angle resolved photoelectron spectroscopy, we measure the valence band dispersion of single-crystal CH_{3}NH_{3}PbBr_{3}. The dispersion of the highest energy band is extracted applying a modified leading edge method, which accounts for the particular density of states of organic-inorganic perovskites. The surface Brillouin zone is consistent with bulk-terminated surfaces both in the low temperature orthorhombic and the high-temperature cubic phase. In the low temperature phase, we find a ring-shaped valence band maximum with a radius of 0.043 A^{-1}, centered around a 0.16 eV deep local minimum in the dispersion of the valence band at the high-symmetry point. Intense circular dichroism is observed. This dispersion is the result of strong spin-orbit coupling. Spin-orbit coupling is also present in the room-temperature phase. The coupling strength is one of the largest ones reported so far.

AB - While being extensively studied as an important physical process to alter exciton population in nanostructures at the fs time scale, carrier multiplication has not been considered seriously as a major mechanism for phase transition. Real-time time-dependent density functional theory study of Ge_{2}Sb_{2}Te_{5} reveals that carrier multiplication can induce an ultrafast phase transition in the solid state despite that the lattice remains cold. The results also unify the experimental findings in other semiconductors for which the explanation remains to be the 30-year old phenomenological plasma annealing model. PMID- 27689287 TI - J_{eff} Description of the Honeycomb Mott Insulator alpha-RuCl_{3}. AB - Novel ground states might be realized in honeycomb lattices with strong spin orbit coupling. Here we study the electronic structure of alpha-RuCl_{3}, in which the Ru ions are in a d^{5} configuration and form a honeycomb lattice, by angle-resolved photoemission, x-ray photoemission, and electron energy loss spectroscopy supported by density functional theory and multiplet calculations. We find that alpha-RuCl_{3} is a Mott insulator with significant spin-orbit coupling, whose low energy electronic structure is naturally mapped onto J_{eff} states. This makes alpha-RuCl_{3} a promising candidate for the realization of Kitaev physics. Relevant electronic parameters such as the Hubbard energy U, the crystal field splitting 10 Dq, and the charge transfer energy Delta are evaluated.

AB - We report subnanometer, high-bandwidth measurements of the out-of-plane (vertical) motion of atoms in freestanding graphene using scanning tunneling microscopy. By tracking the vertical position over a long time period, a 1000 fold increase in the ability to measure space-time dynamics of atomically thin membranes is achieved over the current state-of-the-art imaging technologies. We observe that the vertical motion of a graphene membrane exhibits rare long-scale excursions characterized by both anomalous mean-squared displacements and Cauchy Lorentz power law jump distributions. PMID- 27689289 TI - Observation of the Quantum Anomalous Hall Insulator to Anderson Insulator Quantum Phase Transition and its Scaling Behavior. AB - Fundamental insight into the nature of the quantum phase transition from a superconductor to an insulator in two dimensions, or from one plateau to the next or to an insulator in the quantum Hall effect, has been revealed through the study of its scaling behavior. Here, we report on the experimental observation of a quantum phase transition from a quantum-anomalous-Hall insulator to an Anderson insulator in a magnetic topological insulator by tuning the chemical potential. Our experiment demonstrates the existence of scaling behavior from which we extract the critical exponent for this quantum phase transition. We expect that our work will motivate much further investigation of many properties of quantum phase transition in this new context. PMID- 27689290 TI - Dynamical Buildup of a Quantized Hall Response from Nontopological States. AB - We consider a two-dimensional system initialized in a topologically trivial state before its Hamiltonian is ramped through a phase transition into a Chern insulator regime. This scenario is motivated by current experiments with ultracold atomic gases aimed at realizing time-dependent dynamics in topological insulators. Our main findings are twofold. First, considering coherent dynamics, the nonequilibrium Hall response is found to approach a topologically quantized time-averaged value in the limit of slow but nonadiabatic parameter ramps, even though the Chern number of the state remains trivial. Second, adding dephasing, the destruction of quantum coherence is found to stabilize this Hall response, while the Chern number generically becomes undefined. We provide a geometric picture of this phenomenology in terms of the time-dependent Berry curvature. PMID- 27689291 TI - Transition from Strong to Weak Electronic Coupling in a Single-Molecule Junction. AB - We have investigated charge transport in single-molecule junctions using gold nanoelectrodes at room and cryogenic (10 K) temperatures. A statistical analysis of the low-bias conductance, measured during the stretching of the molecular junctions, shows that the most probable single-molecule conductance is insensitive to the temperature as expected for off-resonant coherent transport. Low-temperature current-voltage measurements show that these junction conformations have a smooth tunnelinglike shape. While separating the electrodes further we find that, in about one-fourth of the cases, the junction switches in an abrupt way to a configuration with I-V characteristics exhibiting a gap around zero bias and resonances at finite bias. The analysis of the I-V shape and of the conductance distance dependence suggests a stretching-induced transition from the strong to the weak electronic coupling regime. The transition involves a large renormalization of the injection barrier and of the electronic coupling between the molecule and the electrodes. PMID- 27689293 TI - Relaxation of a Classical Spin Coupled to a Strongly Correlated Electron System. AB - A classical spin which is antiferromagnetically coupled to a system of strongly correlated conduction electrons is shown to exhibit unconventional real-time dynamics which cannot be described by Gilbert damping. Depending on the strength of the local Coulomb interaction U, the two main electronic dissipation channels, namely transport of excitations via correlated hopping and via excitations of correlation-induced magnetic moments, become active on largely different time scales. We demonstrate that correlations can lead to a strongly suppressed relaxation which so far has been observed in purely electronic systems only and which is governed here by proximity to the divergent magnetic time scale in the infinite-U limit. PMID- 27689292 TI - Origin of the Resistivity Anisotropy in the Nematic Phase of FeSe. AB - The in-plane resistivity anisotropy is studied in strain-detwinned single crystals of FeSe. In contrast to other iron-based superconductors, FeSe does not develop long-range magnetic order below the tetragonal-to-orthorhombic transition at T_{s}~90 K. This allows for the disentanglement of the contributions to the resistivity anisotropy due to nematic and magnetic orders. Comparing direct transport and elastoresistivity measurements, we extract the intrinsic resistivity anisotropy of strain-free samples. The anisotropy peaks slightly below T_{s} and decreases to nearly zero on cooling down to the superconducting transition. This behavior is consistent with a scenario in which the in-plane resistivity anisotropy is dominated by inelastic scattering by anisotropic spin fluctuations. PMID- 27689294 TI - Large Unidirectional Magnetoresistance in a Magnetic Topological Insulator. AB - We report current-direction dependent or unidirectional magnetoresistance (UMR) in magnetic or nonmagnetic topological insulator (TI) heterostructures, Cr_{x}(Bi_{1-y}Sb_{y})_{2-x}Te_{3}/(Bi_{1-y}Sb_{y})_{2}Te_{3}, that is several orders of magnitude larger than in other reported systems. From the magnetic field and temperature dependence, the UMR is identified to originate from the asymmetric scattering of electrons by magnons. In particular, the large magnitude of UMR is an outcome of spin-momentum locking and a small Fermi wave number at the surface of TI. In fact, the UMR is maximized around the Dirac point with the minimal Fermi wave number. PMID- 27689295 TI - Resonant Inelastic X-Ray Scattering Response of the Kitaev Honeycomb Model. AB - We calculate the resonant inelastic x-ray scattering (RIXS) response of the Kitaev honeycomb model, an exactly solvable quantum-spin-liquid model with fractionalized Majorana and flux excitations. We find that the fundamental RIXS channels, the spin-conserving (SC) and the non-spin-conserving (NSC) ones, do not interfere and give completely different responses. SC RIXS picks up exclusively the Majorana sector with a pronounced momentum dispersion, whereas NSC RIXS also creates immobile fluxes, thereby rendering the response only weakly momentum dependent, as in the spin structure factor measured by inelastic neutron scattering. RIXS can, therefore, pick up the fractionalized excitations of the Kitaev spin liquid separately, making it a sensitive probe to detect spin-liquid character in potential material incarnations of the Kitaev honeycomb model. PMID- 27689296 TI - Compensated Semimetal LaSb with Unsaturated Magnetoresistance. AB - By combining angle-resolved photoemission spectroscopy and quantum oscillation measurements, we performed a comprehensive investigation on the electronic structure of LaSb, which exhibits near-quadratic extremely large magnetoresistance (XMR) without any sign of saturation at magnetic fields as high as 40 T. We clearly resolve one spherical and one intersecting-ellipsoidal hole Fermi surfaces (FSs) at the Brillouin zone (BZ) center Gamma and one ellipsoidal electron FS at the BZ boundary X. The hole and electron carriers calculated from the enclosed FS volumes are perfectly compensated, and the carrier compensation is unaffected by temperature. We further reveal that LaSb is topologically trivial but shares many similarities with the Weyl semimetal TaAs family in the bulk electronic structure. Based on these results, we have examined the mechanisms that have been proposed so far to explain the near-quadratic XMR in semimetals. PMID- 27689297 TI - Observation of the Transition from Lasing Driven by a Bosonic to a Fermionic Reservoir in a GaAs Quantum Well Microcavity. AB - We show that, by monitoring the free carrier reservoir in a GaAs-based quantum well microcavity under nonresonant pulsed optical pumping, lasing supported by a fermionic reservoir (photon lasing) can be distinguished from lasing supported by a reservoir of bosons (polariton lasing). Carrier densities are probed by measuring the photocurrent between lateral contacts deposited directly on the quantum wells of a microcavity that are partially exposed by wet chemical etching. We identify two clear thresholds in the input-output characteristic of the photoluminescence signal which can be attributed to polariton and photon lasing, respectively. The power dependence of the probed photocurrent shows a distinct kink at the threshold power for photon lasing due to an increased radiative recombination of free carriers as stimulated emission into the cavity mode sets in. At the polariton lasing threshold, on the other hand, the nonlinear increase of the luminescence is caused by stimulated scattering of exciton polaritons to the ground state which do not contribute directly to the photocurrent. PMID- 27689298 TI - Rotator-to-Lamellar Phase Transition in Janus Colloids Driven by Pressure Anisotropy. AB - We demonstrate through Brownian dynamics simulations a phase transition in plastic crystalline assemblies of Janus spheres through controlled pressure anisotropy. When the pressure in plane with hexagonally ordered layers is increased relative to that normal to the layers, a rapid first-order rotator-to lamellar transition of Janus sphere orientation occurs at constant temperature. We show that the underlying mechanism closely follows the Maier-Saupe theory, originally developed for isotropic-to-nematic transition in positionally disordered materials but here applied to positionally ordered ones. Since the transition involves almost no translational diffusion or volume change, and occurs rapidly by particle rotation, the results should help guide the design of rapidly switchable colloidal crystals. PMID- 27689299 TI - Embodiment of Learning in Electro-Optical Signal Processors. AB - Delay-coupled electro-optical systems have received much attention for their dynamical properties and their potential use in signal processing. In particular, it has recently been demonstrated, using the artificial intelligence algorithm known as reservoir computing, that photonic implementations of such systems solve complex tasks such as speech recognition. Here, we show how the backpropagation algorithm can be physically implemented on the same electro-optical delay-coupled architecture used for computation with only minor changes to the original design. We find that, compared to when the backpropagation algorithm is not used, the error rate of the resulting computing device, evaluated on three benchmark tasks, decreases considerably. This demonstrates that electro-optical analog computers can embody a large part of their own training process, allowing them to be applied to new, more difficult tasks.

AB - The advent of nanophotonic evanescent field trapping and transport platforms has permitted increasingly complex single molecule and single cell studies on-chip. Here, we present the next generation of nanophotonic Standing Wave Array Traps (nSWATs) representing a streamlined CMOS fabrication process and compact biocompatible design. These devices utilize silicon nitride (Si3N4) waveguides, operate with a biofriendly 1064 nm laser, allow for several watts of input power with minimal absorption and heating, and are protected by an anticorrosive layer for sustained on-chip microelectronics in aqueous salt buffers. In addition, due to Si3N4's negligible nonlinear effects, these devices can generate high stiffness traps while resolving subnanometer displacements for each trapped particle. In contrast to traditional table-top counterparts, the stiffness of each trap in an nSWAT device scales linearly with input power and is independent of the number of trapping centers. Through a unique integration of microcircuitry and photonics, the nSWAT can robustly trap, and controllably position, a large number of nanoparticles along the waveguide surface, operating in an all-optical, constant-force mode without need for active feedback. By reducing device fabrication cost, minimizing trapping laser specimen heating, increasing trapping force, and implementing commonly used trapping techniques, this new generation of nSWATs significantly advances the development of a high performance, low cost optical tweezers array laboratory on-chip.

AB - ABSTACT To ensure the safety and efficacy of implantable hearing aids, animal experiments are an essential developmental procedure, in particular, auditory brainstem responses (ABRs) can be used to verify the objective effectiveness of implantable hearing aids. This study measured and compared the ABRs generated when applying the same vibration stimuli to an oval window and round window. The ABRs were measured using a TDT system 3 (TDT, USA), while the vibration stimuli were applied to a round window and oval window in 4 guinea pigs using a piezo electric transducer with a proper contact tip. A paired t-test was used to determine any differences between the ABR amplitudes when applying the stimulation to an oval window and round window. The paired t-test revealed a significant difference between the ABR amplitudes generated by the round and oval window stimulation (t = 10.079, alpha < .0001). Therefore, the results confirmed that the biological response to round window stimulation was not the same as that to oval window stimulation. PMID- 27689305 TI - Energy evaluation of protection effectiveness of anti-vibration gloves. AB - This article describes an energy method of assessing protection effectiveness of anti-vibration gloves on the human dynamic structure. The study uses dynamic models of the human and the glove specified in Standard No. ISO 10068:2012. The physical models of human-tool systems were developed by combining human physical models with a power tool model. The combined human-tool models were then transformed into mathematical models from which energy models were finally derived. Comparative energy analysis was conducted in the domain of rms powers. The energy models of the human-tool systems were solved using numerical simulation implemented in the MATLAB/Simulink environment. The simulation procedure demonstrated the effectiveness of the anti-vibration glove as a method of protecting human operators of hand-held power tools against vibration. The desirable effect is achieved by lowering the flow of energy in the human-tool system when the anti-vibration glove is employed.

AB - The effects of immersion of green asparagus spears in stigmasterol solution (0, 0.5 and 1.0 g l-1, 15 min, 25 degrees C) on weight loss, surface colour, enzyme activities and content of malondialdehyde, total phenol, lignin and chlorophyll were investigated during 40 days of storage at 4 +/- 0.5 degrees C. Of the concentrations tested, 0.5 g l-1 treatment was most effective. Stigmasterol (0.5 g l-1) treatment significantly reduced colour changes and losses of fresh weight and chlorophyll content. Superoxide dismutase (SOD) and catalase (CAT) activities were maintained higher in stigmasterol-treated (0.5 g l-1) asparagus, whereas the activity of peroxidase (POD) was significantly reduced. Stigmasterol treatment (0.5 g l-1) also significantly decreased the content of malondialdehyde (MDA) and increased total phenol content. Accumulation of lignin was positively correlated to activity of guaiacol-POD (r = 0.960, p < 0.01) in stigmasterol-treated (0.5 g l-1) asparagus. The polyphenol oxidase (PPO) activity decreased and showed a significant negative correlation with the chroma L* value (r = -0.899, p < 0.01) in stigmasterol-treated (0.5 g l-1) asparagus. It was concluded that stigmasterol treatment (0.5 g l-1) could inhibit the senescence of green asparagus, and therefore prolong its shelf-life, maintaining the quality of post-harvest green asparagus. PMID- 27689306 TI - Tobacco 21: An Important Public Policy to Protect Our Youth. AB - An important approach to reduce youth tobacco use is the adoption of regulations to prohibit tobacco product sale to individuals younger than 21 years, termed Tobacco 21. In the United States, close to 90% of current smokers started smoking before the age of 18 years, and 99% before age 26 years. Earlier age of tobacco use initiation is associated with lower rates of smoking cessation. Increasing minimum age to purchase has been shown to reduce tobacco product use among youth. The critical determinant is likely the loss of social sources of tobacco products. Enforcement activities are important for age-of-purchase laws to be effective. Raising the minimum legal age to purchase tobacco products to 21 years is highly supported among both the smoking and nonsmoking public. Tobacco sales to those younger than 21 years account for just 2% of total tobacco sales, yet produce 90% of new smokers. The short-term effect on small business of raising the minimum age to purchase would be minimal. Small businesses will have time to adapt to the decrease in tobacco sales as fewer youth grow up nicotine addicted. Raising the minimum age to purchase of tobacco and nicotine products to 21 years, combined with enforcement of those restrictions, will help protect future generations from a lifetime of tobacco dependence and associated morbidity. These regulations should apply to all tobacco products, including electronic nicotine delivery systems. Respiratory health care providers should educate their local, state, and federal policy makers on the importance of Tobacco 21.

AB - Among the radiotherapeutics' modalities, total body irradiation (TBI) is used as treatment for certain hematological, oncological and immunological diseases. The aim of this study was to evaluate the long-term effects of low-dose TBI on plasma concentration of total protein and albumin using prematurely and undernourished rats as animal model. For this, four groups with 9 animals each were formed: Normal nourished (N); Malnourished (M); Irradiated Normal nourished (IN); Irradiated Malnourished (IM). At the age of 28 days, rats of the IN and IM groups underwent total body gamma irradiation with a source of cobalt-60. Total protein and Albumin in the blood serum was quantified by colorimetry. This research indicates that procedures involving low-dose total body irradiation in children have repercussions in the reduction in body-mass as well as in the plasma levels of total protein and albumin. Our findings reinforce the periodic monitoring of total serum protein and albumin levels as an important tool in long-term follow up of pediatric patients in treatments associated to total body irradiation. PMID- 27689308 TI - Determination of the conventional true value of gamma-ray air kerma in a minitype reference radiation. AB - To develop mobile calibration equipment for gamma-ray dose or dose rate meters in the field of radiation protection, a minitype reference radiation (MRR) of 0.5m*0.5m*0.5m cube was set up and used for investigation. Two types, which add up to 12 daily used gamma-ray dose rate meters, were used as samples to determine the conventional true value of air kerma (CAK) at the point of test in the MRR. A gamma-ray spectrometer was also used to monitor the scattering gamma rays in the MRR, which were applied further to characterize the disturbance of scattering gamma ray in CAK determination. On the basis of the sample data sets of CAKs, scattering gamma spectra and air kerma values at the point of test without sample meters, a CAK prediction model at the point of test was developed by the least square support vector machine, which is a multiple nonlinear regression method. For reducing the amount of data and improving the regression efficiency, principal component analysis (PCA) was used to extract feature components from the scattering gamma-ray spectra before regression. A relative standard uncertainty of 4.65% was achieved in determining CAK in the MRR using the constructed prediction model. PMID- 27689309 TI - A novel method of combined detector model for gamma-ray densitometer: Theoretical calculation and MCNP4C simulation. AB - This study focuses on investigating a new model of combined backscatter and transmission method for nuclear densitometer. In this method for density measurement, a true combination of transmission and backscatter methods was studied and related equations were developed. The MCNP4C code was used for simulation of this combined detector model (CDM) and by applying theoretical calculations, density equation was corrected for the proposed nuclear densitometer. In the new method presented here, the buildup effect was estimated by an online system that was improved in our laboratory and was replaced by a new conceptual calculation. Hence, for the purpose of buildup reduction, there was no need for the shield around the detector, as it was monitored and reduced online. Furthermore, this study showed that the RSQ function could be improved by the CDM. The measurement technique proposed in this study has a better linearity trend than the transmission technique. Thus, the ability of CDM to improve the accuracy of the nuclear densitometer was shown.

PMID- 27689311 TI - Gaseous nitrous acid (HONO) and nitrogen oxides (NOx) emission from gasoline and diesel vehicles under real-world driving test cycles. AB - : Reactive nitrogen species emission from the exhausts of gasoline and diesel vehicles, including nitrogen oxides (NOx) and nitrous acid (HONO), contributes as a significant source of photochemical oxidant precursors in the ambient air. Multiple laboratory and on-road exhaust measurements have been performed to estimate the NOx emission factors from various vehicles and their contribution to atmospheric pollution. Meanwhile, HONO emission from vehicle exhaust has been under-measured despite the fact that HONO can contribute up to 60% of the total hydroxyl budget during daytime and its formation pathway is not fully understood. A profound traffic-induced HONO to NOx ratio of 0.8%, established by Kurtenbach et al. since 2001, has been widely applied in various simulation studies and possibly linked to under-estimation of HONO mixing ratios and OH radical budget in the morning. The HONO/NOx ratios from direct traffic emission have become debatable when it lacks measurements for direct HONO emission from vehicles upon the fast-changing emission reduction technology. Several recent studies have reported updated values for this ratio. This study has reported the measurement of HONO and NOx emission as well as the estimation of exhaust-induced HONO/NOx ratios from gasoline and diesel vehicles using different chassis dynamometer tests under various real-world driving cycles. For the tested gasoline vehicle, which was equipped with three-way catalyst after-treatment device, HONO/NOx ratios ranged from 0 to 0.95 % with very low average HONO concentrations. For the tested diesel vehicle equipped with diesel particulate active reduction device, HONO/NOx ratios varied from 0.16 to 1.00 %. The HONO/NOx ratios in diesel exhaust were inversely proportional to the average speeds of the tested vehicles. IMPLICATIONS: Photolysis of HONO is a dominant source of morning OH radicals. Conventional traffic-induced HONO/NOx ratio of 0.8% has possibly linked to underestimation of the total HONO budget and consequently underestimation of OH radical budget. The recently reported HONO/NOx ratio of ~1.6% was used to stimulate HONO emission, which resulted in increased HONO concentrations during morning peak hours and its impact of 14% OH increment in the morning. However, the results were still lower than the measured concentrations. More studies should be conducted to establish an updated traffic-induced HONO/NOx ratio. PMID- 27689312 TI - The effects of informal carers' characteristics on their information needs: The information needs state approach. AB - BACKGROUND: There has been little research that provides a comprehensive account of the nature and aspects of information needs of informal carers. The authors have previously developed and validated a framework that accounts for major underlying states of information need. This paper aims to apply this framework to explore whether there are common demographic and socioeconomic characteristics that affect the information needs states of carers. A questionnaire about the information needs states was completed by 198 carers above 18 years old. We use statistical methods to look for similarities and differences in respondents' information needs states, in terms of the demographic and socioeconomic variables. At least one information needs state varies among carers, in terms of seven demographic and socioeconomic variables: the age of the patient(s) that they are caring for; the condition(s) of the patient(s) that they are caring for; the number of patients that they are caring for; their length of time as a carer; their gender; the country that they live in; and the population of the area that they live in. The findings demonstrate the utility of the information needs state framework. We outline some practical implications of the framework. PMID- 27689313 TI - A review of fundamental principles for animal models of DOHaD research: an Australian perspective. AB - Epidemiology formed the basis of 'the Barker hypothesis', the concept of 'developmental programming' and today's discipline of the Developmental Origins of Health and Disease (DOHaD). Animal experimentation provided proof of the underlying concepts, and continues to generate knowledge of underlying mechanisms. Interventions in humans, based on DOHaD principles, will be informed by experiments in animals. As knowledge in this discipline has accumulated, from studies of humans and other animals, the complexity of interactions between genome, environment and epigenetics, has been revealed. The vast nature of programming stimuli and breadth of effects is becoming known. As a result of our accumulating knowledge we now appreciate the impact of many variables that contribute to programmed outcomes. To guide further animal research in this field, the Australia and New Zealand DOHaD society (ANZ DOHaD) Animals Models of DOHaD Research Working Group convened at the 2nd Annual ANZ DOHaD Congress in Melbourne, Australia in April 2015. This review summarizes the contributions of animal research to the understanding of DOHaD, and makes recommendations for the design and conduct of animal experiments to maximize relevance, reproducibility and translation of knowledge into improving health and well-being.

AB - We report the design, synthesis, detailed characterization, and analysis of a new multifunctional pi-conjugated bola-amphiphilic chromophore: oligo-(p phenyleneethynylene)dicarboxylic acid with dialkoxyoctadecyl side chains (OPE-C18 1). OPE-C18-1 shows two polymorphs at 123 K (OPE-C18-1') and 373 K (OPE-C18-1"), whose crystal structures were characterized via single crystal X-ray diffraction. OPE-C18-1 also exhibits thermotropic liquid crystalline property revealing a columnar phase. The inherent pi-conjugation of OPE-C18-1 imparts luminescence to the system. Photoluminescence measurements on the mesophase also reveal similar luminescence as in the crystalline state. Additionally, OPE-C18-1 shows mechano hypsochromic luminescence behavior. Density functional theory (DFT)-based calculations unravel the origins behind the simultaneous existence of all these properties. Nanoindentation experiments on the single crystal reveal its mechanical strength and accurately correlate the molecular arrangement with the liquid crystalline and mechanochromic luminescence behavior.

AB - OBJECTIVE: In this study, randomized controlled interventional study pattern was used to examine the effects of the "First You Should Get Stronger" program on the caregiving burden and healthy life style behavior of caregivers of dementia patients. METHODS: "Zarit Caregiver Burden Scale" and "Healthy Life Style Behavior Scale" were used. The study was completed with 40 caregivers in total with 20 in the intervention group and 20 in the control group. A statistically significant difference was determined between the "Zarit Caregiving Burden Scale" and "Healthy Life Style Behavior Scale" score averages of the intervention group that participated in the "First You Should Get Stronger" program in comparison with those of the control group. RESULTS: It is important for the healths of caregivers to include similar programs for the caregivers of dementia patients in continuous and regular applications. DISCUSSION: The results highlight the importance of the "First You Should Get Stronger" program significantly decreased the caregiving burden and significantly developed the healthy lifestyle behaviors of caregivers in the intervention group. Since dementia is a difficult neurological syndrome with patients cared at home, it generally wears out the caregivers significantly. It is suggested that the nurses and healthcare professionals working with dementia patients are evaluated separately and that they carry out caregiving applications within the scope of the "First You Should Get Stronger" program. PMID- 27689316 TI - Results of scalp cooling during anthracycline containing chemotherapy depend on scalp skin temperature. AB - OBJECTIVES: The success of scalp cooling in preventing or reducing chemotherapy induced alopecia (CIA) is highly variable between patients undergoing similar chemotherapy regimens. A decrease of the scalp skin temperature seems to be an important factor, but data on the optimum temperature reached by scalp cooling to prevent CIA are lacking. This study investigated the relation between scalp skin temperature and its efficacy to prevent CIA. MATERIALS AND METHODS: In this explorative study, scalp skin temperature was measured during scalp cooling in 62 breast cancer patients undergoing up to six cycles of anthracycline containing chemotherapy. Scalp skin temperature was measured by using two thermocouples at both temporal sides of the head. The primary end-point was the need for a wig or other head covering. RESULTS: Maximal cooling was reached after 45 min and was continued for 90 min after chemotherapy infusion. The scalp skin temperature after 45 min cooling varied from 10 degrees C to 31 degrees C, resulting in a mean scalp skin temperature of 19 degrees C (SEM: 0,4). Intrapersonal scalp skin temperatures during cooling were consistent for each chemotherapy cycle (ANOVA: P = 0,855). Thirteen out of 62 patients (21%) did not require a wig or other head covering. They appeared to have a significantly lower mean scalp skin temperature (18 degrees C; SEM: 0,7) compared to patients with alopecia (20 degrees C; SEM: 0,5) (P = 0,01). CONCLUSION: The efficacy of scalp cooling during chemotherapy is temperature dependent. A precise cut-off point could not be detected, but the best results seem to be obtained when the scalp temperature decreases below 18 degrees C. TRIALREGISTER. NL NTR NUMBER: 3082.

PMID- 27689317 TI - The effect of in-hospital acquired thrombocytopenia on the outcome of patients with acute coronary syndromes: A systematic review and meta-analysis. AB - BACKGROUND: In-hospital acquired thrombocytopenia (TP) is relatively common among patients hospitalized with acute coronary syndromes (ACS). However, its effect on short-term and long-term outcomes has yet to be reviewed systematically. METHODS: We conducted a systematic review and meta-analysis of clinical studies assessing the relationship between new-onset in-hospital TP and adverse outcomes among ACS patients. MEDLINE, Scopus and the Cochrane Library were searched for eligible studies published before March 20, 2016. RESULTS: Ten studies reporting on a total of 142,161 ACS patients were identified. 8133 patients showed evidence of new-onset TP during the course of their hospitalization. Compared with patients with normal platelet counts, patients with new-onset TP had a prolonged in hospital stay, significantly higher risk of both short-term mortality (<30days) (Odds ratio (OR) [95% confidence interval (CI)]: 5.58 [3.63-8.57]) and late death (6months to 1year) (OR [95% CI]: 3.45 [2.35-5.07]), as well as a significantly higher risk of major bleeding events in the first 30days (OR [95% CI]: 6.93 [5.13 9.38]). In addition, risk for other secondary cardiovascular endpoints, including recurrent myocardial infarction, stroke, in-hospital heart failure, stent thrombosis and unplanned revascularization was also significantly higher in the TP versus the no TP group. CONCLUSIONS: Development of TP during the in-hospital management of ACS patients is a significant predictor of both short- and long term adverse events, including mortality. In the light of this evidence, clinicians should be cautious and closely monitor abnormal platelet counts that present early following an ACS. PMID- 27689319 TI - Field-based Evaluation of a Novel SPME-GC-MS Method for Investigation of Below ground Interaction between Brassica Roots and Larvae of Cabbage Root Fly, Delia radicum L. AB - INTRODUCTION: Collection of volatiles from plant roots poses technical challenges due to difficulties accessing the soil environment without damaging the roots. OBJECTIVES: To validate a new non-invasive method for passive sampling of root volatiles in situ, from plants grown under field conditions, using solid phase micro-extraction (SPME). METHODS: SPME fibres were inserted into perforated polytetrafluoroethene (PTFE) tubes positioned in the soil next to broccoli plants for collection of root volatiles pre- and post-infestation with Delia radicum larvae. After sample analysis by gas chromatography-mass spectrometry (GC-MS), principal component analysis (PCA) was applied to determine differences in the profiles of volatiles between samples. RESULTS: GC-MS analysis revealed that this method can detect temporal changes in root volatiles emitted before and after Delia radicum damage. PCA showed that samples collected pre- and post-infestation were compositionally different due to the presence of root volatiles induced by D. radicum feeding. Sulphur containing compounds, in particular, accounted for the differences observed. Root volatiles emission patterns post-infestation are thought to follow the feeding and developmental progress of larvae. CONCLUSION: This study shows that volatiles released by broccoli roots can be collected in situ using SPME fibres within perforated PTFE tubes under field conditions. Plants damaged by Delia radicum larvae could be distinguished from plants sampled pre-infestation and soil controls on the basis of larval feeding-induced sulphur containing volatiles. These results show that this new method is a powerful tool for non-invasive sampling of root volatiles below-ground. Copyright (c) 2016 John Wiley & Sons, Ltd.

PMID- 27689320 TI - Local depletion of glycogen with supramaximal exercise in human skeletal muscle fibres. AB - KEY POINTS: Glycogen is stored in local spatially distinct compartments within skeletal muscle fibres and is the main energy source during supramaximal exercise. Using quantitative electron microscopy, we show that supramaximal exercise induces a differential depletion of glycogen from these compartments and also demonstrate how this varies with fibre types. Repeated exercise alters this compartmentalized glycogen depletion. The results obtained in the present study help us understand the muscle metabolic dynamics of whole body repeated supramaximal exercise, and suggest that the muscle has a compartmentalized local adaptation to repeated exercise, which affects glycogen depletion. ABSTRACT: Skeletal muscle glycogen is heterogeneously distributed in three separated compartments (intramyofibrillar, intermyofibrillar and subsarcolemmal). Although only constituting 3-13% of the total glycogen volume, the availability of intramyofibrillar glycogen is of particular importance to muscle function. The present study aimed to investigate the depletion of these three subcellular glycogen compartments during repeated supramaximal exercise in elite athletes. Ten elite cross-country skiers (aged 25 +/- 4 years, VO2 max : 65 +/- 4 ml kg-1 min-1 ; mean +/- SD) performed four ~4 min supramaximal sprint time trials (STT 1 4) with 45 min of recovery. The subcellular glycogen volumes in musculus triceps brachii were quantified from electron microscopy images before and after both STT 1 and 4. During STT 1, the depletion of intramyofibrillar glycogen was higher in type 1 fibres [-52%; (-89:-15%)] than type 2 fibres [-15% (-52:22%)] (P = 0.02), whereas the depletion of intermyofibrillar glycogen [main effect: -19% (-33:0%), P = 0.006] and subsarcolemmal glycogen [main effect: -35% (-66:0%), P = 0.03] was similar between fibre types. By contrast, only intermyofibrillar glycogen volume was significantly reduced during STT 4, in both fibre types [main effect: -31% ( 50:-11%), P = 0.002]. Furthermore, for each of the subcellular compartments, the depletion of glycogen during STT 1 was associated with the volumes of glycogen before STT 1. In conclusion, the depletion of spatially distinct glycogen compartments differs during supramaximal exercise. Furthermore, the depletion changes with repeated exercise and is fibre type-dependent. PMID- 27689322 TI - Case-specific potentiation of glioblastoma drugs by pterostilbene. AB - Glioblastoma multiforme (GBM, astrocytoma grade IV) is the most common malignant primary brain tumor in adults. Addressing the shortage of effective treatment options for this cancer, we explored repurposing of existing drugs into combinations with potent activity against GBM cells. We report that the phytoalexin pterostilbene is a potentiator of two drugs with previously reported anti-GBM activity, the EGFR inhibitor gefitinib and the antidepressant sertraline. Combinations of either of these two compounds with pterostilbene suppress cell growth, viability, sphere formation and inhibit migration in tumor GBM cell (GC) cultures. The potentiating effect of pterostilbene was observed to a varying degree across a panel of 41 patient-derived GCs, and correlated in a case specific manner with the presence of missense mutation of EGFR and PIK3CA and a focal deletion of the chromosomal region 1p32. We identify pterostilbene induced cell cycle arrest, synergistic inhibition of MAPK activity and induction of Thioredoxin interacting protein (TXNIP) as possible mechanisms behind pterostilbene's effect. Our results highlight a nontoxic stilbenoid compound as a modulator of anticancer drug response, and indicate that pterostilbene might be used to modulate two anticancer compounds in well-defined sets of GBM patients.

AB - In this study, we assessed the association between single nucleotide polymorphisms (SNPs) in candidate genes and the prognosis of laryngeal cancer (LC) patients. Thirty-seven SNPs in 26 genes were genotyped in 170 male Han Chinese patients with LC. The effects of the candidate genes on the prognosis of LC patients were evaluated using Kaplan-Meier curves and Cox proportional hazards regression models. The GA genotype of rs1229984 (hazard ratio [HR], 0.537; 95% confidence interval [CI], 0.340-0.848; p = 0.008) in alcohol dehydrogenase 1B (ADH1B), and the AA genotype of rs9929218 (HR, 6.074; 95% CI, 1.426-25.870; p = 0.015) in CDH1 were associated with overall survival. Our data suggest that polymorphisms in ADH1B and CDH1 may be prognostic indicators in LC. PMID- 27689324 TI - Enhancement of endothelial permeability by free fatty acid through lysosomal cathepsin B-mediated Nlrp3 inflammasome activation. AB - Obesity is an important risk factor for exacerbating chronic diseases such as cardiovascular disease and cancer. High serum level of saturated free fatty acids such as palmitate is an important contributor for obesity-induced diseases. Here, we examined the contribution of inflammasome activation in vascular cells to free fatty acid-induced endothelial dysfunction and vascular injury in obesity. Our findings demonstrated that high fat diet-induced impairment of vascular integrity and enhanced vascular permeability in the myocardium in mice were significantly attenuated by Nlrp3 gene deletion. In microvascular endothelial cells (MVECs), palmitate markedly induces Nlrp3 inflammasome complex formation leading to caspase-1 activation and IL1beta production. By fluorescence microscopy and flow cytometry, we observed that such palmitate-induced Nlrp3 inflammasome activated was accompanied by a reduction in inter-endothelial tight junction proteins ZO 1/ZO-2. Such palmitate-induced decrease of ZO-1/ZO-2 was also correlated with an increase in the permeability of endothelial monolayers treated with palmitates. Moreover, palmitate-induced alterations in ZO-1/ZO-2 or permeability were significantly reversed by an inflammasome activity inhibitor, YVAD, or a high mobility group box 1 (HMGB1) activity inhibitor glycyrrhizin. Lastly, blockade of cathepsin B with Ca-074Me significantly abolished palmitate-induced activation of Nlrp3 inflammasomes, down-regulation of ZO-1/ZO-2, and enhanced permeability in MVECs or their monolayers. Together, these data strongly suggest that activation of endothelial inflammasomes due to increased free fatty acids produces HMGB1, which disrupts inter-endothelial junctions and increases paracellular permeability of endothelium contributing to early onset of endothelial injury during obesity. PMID- 27689325 TI - Catalytically defective receptor protein tyrosine kinase PTK7 enhances invasive phenotype by inducing MMP-9 through activation of AP-1 and NF-kappaB in esophageal squamous cell carcinoma cells. AB - Protein tyrosine kinase 7 (PTK7), a member of the catalytically defective receptor protein tyrosine kinase family, is upregulated in various cancers including esophageal squamous cell carcinoma (ESCC). Here, we have explored the molecular mechanism of PTK7-dependent invasiveness in ESCC cells. PTK7 knockdown reduced gelatin degradation and MMP-9 secretion in cultures of ESCC TE-10 cells, and showed reduced levels of MMP9 mRNA using real-time RT-PCR and luciferase reporter assays. PTK7 knockdown decreased not only phosphorylation of NF-kappaB, IkappaB, ERK, and JNK, but also nuclear localization of NF-kappaB and AP-1 consisting of c-Fos and c-Jun. Activation of AP-1 and NF-kappaB requires PTK7 mediated activation of tyrosine kinases, including Src. In addition, NF-kappaB activation by PTK7 involves the PI3K/Akt signaling pathway. PTK7-mediated upregulation of MMP9 was also observed in other ESCC cell lines and in three dimensional cultures of TE-10 cells. Moreover, MMP-9 expression positively correlated with PTK7 expression in ESCC tumor tissue. These findings demonstrate that PTK7 upregulates MMP9 through activation of AP-1 and NF-kappaB and, thus increases invasive properties of ESCC cells. PMID- 27689326 TI - An artificial lncRNA targeting multiple miRNAs overcomes sorafenib resistance in hepatocellular carcinoma cells. AB - Sorafenib resistance remains a major obstacle for the effective treatment of hepatocellular carcinoma (HCC), and a number of miRNAs contribute to this resistance. However, the regulatory networks of miRNAs are very complex, thus inhibiting a single miRNA may sequentially activate other compensatory pathways. In the present study, we generated an artificial long non-coding RNA (AlncRNA), which simultaneously targets multiple miRNAs including miR-21, miR-153, miR-216a, miR-217, miR-494 and miR-10a-5p. These miRNAs have been shown to be upregulated in sorafenib-resistant cells and participate in the mechanisms underlying sorafenib resistance. The AlncRNA contains tandem sequences of 6 copies of the complementary binding sequences to the target miRNAs and is expressed by an adenoviral vector (Ad5-AlncRNA). Infection of Ad5-AlncRNA into sorafenib resistant HCC cells blocked the function of miRNAs, and sequentially inhibited the downregulation of PTEN and activation of AKT. Ad5-AlncRNA significantly inhibited proliferation and induced apoptosis of sorafenib-resistant cells and enhanced the effects of sorafenib in vitro and in animal models. Inhibition of autophagy decreased the sensitivity of sorafenib-resistant cells to Ad5-AlncRNA, while its induction had the opposite effect. These results indicate that targeting multiple miRNAs by the artificial lncRNA could be a potential promising strategy for overcoming sorafenib resistance in the treatment of HCC. PMID- 27689327 TI - Low carbohydrate diet prevents Mcl-1-mediated resistance to BH3-mimetics. AB - Overexpression of Mcl-1 is implicated in resistance of several cancers to chemotherapeutic treatment, therefore identifying a safe way to decrease its expression in tumor cells represents a central goal. We investigated if a modulation of the diet could impact on Mcl-1 expression using a Myc-driven lymphoma model. We established that a partial reduction of caloric intake by 25% represents an efficient way to decrease Mcl-1 expression in tumor cells. Furthermore, using isocaloric custom diets, we observed that carbohydrates (CHO) are the main regulators of Mcl-1 expression within the food. Indeed, feeding lymphoma-bearing mice with a diet having 25% less carbohydrates was sufficient to decrease Mcl-1 expression by 50% in lymphoma cells. We showed that a low CHO diet resulted in AMPK activation and mTOR inhibition leading to eukaryotic elongation factor 2 (eEF2) inhibition, blocking protein translation elongation. Strikingly, a low CHO diet was sufficient to sensitize Myc-driven lymphoma-bearing mice to ABT-737-induced cell death in vivo. Thus reducing carbohydrate intake may represent a safe way to decrease Mcl-1 expression and to sensitize tumor cells to anti-cancer therapeutics. PMID- 27689328 TI - c-MYC drives histone demethylase PHF8 during neuroendocrine differentiation and in castration-resistant prostate cancer. AB - Epigenetic factors play critical roles in prostate cancer (PCa) development. However, how they contribute to neuroendocrine differentiation (NED) and castration-resistant PCa (CRPC) is not fully understood. Using bioinformatics and biochemical approaches to analyze cell-based models of NED and CRPC, we found a cluster of epigenetic factors whose expression is downregulated during NED and upregulated in CRPC (i.e. follow a Down-Up pattern). Two histone demethylases within this cluster, PHF8 and KDM3A, are post-transcriptionally regulated by c MYC through miR-22, which targets both PHF8 and KDM3A. We also found that the c MYC/miR-22/PHF8 axis is downstream of androgen receptor (AR) signaling in CRPC cells. The co-expression of PHF8 with AR in clinical CRPC samples, normal mouse prostate, and adenocarcinomas of the prostate during PCa progression in a transgenic (TRAMP) mouse model supports the connection between PHF8 and AR. Knockdown of PHF8 impedes cell cycle progression in CRPC cells and has more profound effects on their growth than on the parental LNCaP cell line. Furthermore, PHF8 knockdown sensitizes LNCaP-Abl cells to the AR antagonist enzalutamide. Our data reveal novel mechanisms that underlie the regulation of PHF8 and KDM3A during NED and in CRPC, and support the candidacy of PHF8 as a therapeutic target in CRPC. PMID- 27689329 TI - Age and cellular context influence rectal prolapse formation in mice with caecal wall colorectal cancer xenografts. AB - In patients with rectal prolapse is the prevalence of colorectal cancer increased, suggesting that a colorectal tumor may induce rectal prolapse. Establishment of tumor xenografts in immunodeficient mice after orthotopic inoculations of human colorectal cancer cells into the caecal wall is a widely used approach for the study of human colorectal cancer progression and preclinical evaluation of therapeutics. Remarkably, 70% of young mice carrying a COLO320DM caecal tumor showed symptoms of intussusception of the large bowel associated with intestinal lumen obstruction and rectal prolapse. The quantity of the COLO320DM bioluminescent signal of the first three weeks post-inoculation predicts prolapse in young mice. Rectal prolapse was not observed in adult mice carrying a COLO320DM caecal tumor or young mice carrying a HT29 caecal tumor. In contrast to HT29 tumors, which showed local invasion and metastasis, COLO320DM tumors demonstrated a non-invasive tumor with pushing borders without presence of metastasis. In conclusion, rectal prolapse can be linked to a non-invasive, space occupying COLO320DM tumor in the gastrointestinal tract of young immunodeficient mice. These data reveal a model that can clarify the association of patients showing rectal prolapse with colorectal cancer. PMID- 27689330 TI - Interconnections between apoptotic and autophagic pathways during thiopurine induced toxicity in cancer cells: the role of reactive oxygen species. AB - Thiopurines (azathioprine, 6-mercaptopurine and 6-thioguanine) are a class of genotoxic drugs extensively used in the treatment of various illnesses including leukemia. Their underlying molecular mechanism of action involves the activation of apoptosis and autophagy but remains widely unclear. Here we present evidence that autophagy induction by thiopurines is a survival mechanism that antagonizes apoptosis and is involved in degrading damaged mitochondria through mitophagy. On the other hand, apoptosis is the main cell death mechanism by thiopurines as its inhibition prohibited cell death. Thus a tight interplay between apoptosis and autophagy controls cell fate in response to thiopurine treatment. Moreover, thiopurines disrupt mitochondrial function and induce a loss of the mitochondrial transmembrane potential. The involvement of the mitochondrial pathway in thiopurine-induced apoptosis was further confirmed by increased formation of reactive oxygen species (ROS). Inhibiting oxidative stress protected the cells from thiopurine-induced cell death and ROS scavenging prohibited autophagy induction by thiopurines. Our data indicate that the anticarcinogenic effects of thiopurines are mediated by complex interplay between cellular mechanisms governing redox homeostasis, apoptosis and autophagy. PMID- 27689331 TI - Fluorescence-guided surgery of a highly-metastatic variant of human triple negative breast cancer targeted with a cancer-specific GFP adenovirus prevents recurrence. AB - We have previously developed a genetically-engineered GFP-expressing telomerase dependent adenovirus, OBP-401, which can selectively illuminate cancer cells. In the present report, we demonstrate that targeting a triple-negative high-invasive human breast cancer, orthotopically-growing in nude mice, with OBP-401 enables curative fluorescence-guided surgery (FGS). OBP-401 enabled complete resection and prevented local recurrence and greatly inhibited lymph-node metastasis due to the ability of the virus to selectively label and subsequently kill cancer cells. In contrast, residual breast cancer cells become more aggressive after bright (white)-light surgery (BLS). OBP-401-based FGS also improved the overall survival compared with conventional BLS. Thus, metastasis from a highly-aggressive triple negative breast cancer can be prevented by FGS in a clinically-relevant mouse model. PMID- 27689332 TI - Whole-exome sequencing of muscle-invasive bladder cancer identifies recurrent copy number variation in IPO11 and prognostic significance of importin-11 overexpression on poor survival. AB - Non-muscle-invasive bladder cancer (NMIBC) often has a worse prognosis following its progression to muscle-invasive bladder cancer (MIBC), despite radical cystectomy with pelvic lymph node dissection combined with chemotherapy. Therefore, the discovery of novel biomarkers for predicting the progression of this disease and of therapeutic targets for preventing it is crucial. We performed whole-exome sequencing to analyze superficial tumor tissues (Tsup) and basal tumor tissues (Tbas) from 3 MIBC patients and identified previously unreported copy number variations in IPO11 that warrants further investigation as a molecular target. In addition, we identified a significant association between the absolute copy number and mRNA expression of IPO11 and found that high importin-11 expression was correlated with poor 3-year overall survival (OS), cancer-specific survival (CSS) and cancer-free survival (CFS) compared with low expression in the BCa patients. Importin-11 overexpression was also an independent risk factor for CSS and CFS in the BCa patients. Our study has revealed that IPO11 copy number amplification contributes to its overexpression and that these changes are unfavorable prognostic factors in NMIBC. Thus, IPO11 copy number amplification and importin-11 overexpression are promising biomarkers for predicting the progression and poor prognosis of patients with NMIBC. PMID- 27689333 TI - Curcumin targets the TFEB-lysosome pathway for induction of autophagy. AB - Curcumin is a hydrophobic polyphenol derived from the herb Curcumalonga and its wide spectrum of pharmacological activities has been widely studied. It has been reported that Curcumin can induce autophagy through inhibition of the Akt-mTOR pathway. However, the effect of Curcumin on lysosome remains largely elusive. In this study, we first found that Curcumin treatment enhances autophagic flux in both human colon cancer HCT116 cells and mouse embryonic fibroblasts (MEFs). Moreover, Curcumin treatment promotes lysosomal function, evidenced by the increased lysosomal acidification and enzyme activity. Second, Curcumin is capable of suppressing the mammalian target of rapamycin (mTOR). Interestingly, Curcumin fails to inhibit mTOR and to activate lysosomal function in Tsc2-/-MEFs with constitutive activation of mTOR, indicating that Curcumin-mediated lysosomal activation is achieved via suppression of mTOR. Third, Curcumin treatment activates transcription factor EB (TFEB), a key nuclear transcription factor in control of autophagy and lysosome biogenesis and function, based on the following observations: (i) Curcumin directly binds to TFEB, (ii) Curcumin promotes TFEB nuclear translocation; and (iii) Curcumin increases transcriptional activity of TFEB. Finally, inhibition of autophagy and lysosome leads to more cell death in Curcumin-treated HCT116 cells, suggesting that autophagy and lysosomal activation serves as a cell survival mechanism to protect against Curcumin-mediated cell death. Taken together, data from our study provide a novel insight into the regulatory mechanisms of Curcumin on autophagy and lysosome, which may facilitate the development of Curcumin as a potential cancer therapeutic agent. PMID- 27689334 TI - Clinicopathological characteristics and long-term prognosis of screening detected non-palpable breast cancer by ultrasound in hospital-based Chinese population (2001-2014). AB - PURPOSE: The mainstay modality of breast cancer screening in China is the hospital-based opportunistic screening among asymptomatic self-referred women. There is little data about the ultrasound (US) detected non-palpable breast cancer (NPBC) in Chinese population. METHODS: We analyzed 699 consecutive NPBC from 1.8-2.3 million asymptomatic women from 2001 to 2014, including 572 US detected NPBC from 3,786 US-positive women and 127 mammography (MG) detected NPBC from 788 MG-positive women. The clinicopathological features, disease-free survival (DFS) and overall survival (OS) were compared between the US- and MG detected NPBC. Prognostic factors of NPBC were identified. RESULTS: Compared to MG, US could detect more invasive NPBC (83.6% vs 54.3%, p<0.001), lymph node positive NPBC (19.1% vs 10.2%, p=0.018), lower grade (24.8% vs 16.5%, p<0.001), multifocal (19.2% vs 6.3%, p<0.001), PR positive (71.4% vs 66.9%, p=0.041), Her2 negative (74.3% vs 54.3%, p<0.001), Ki67 high (defined as >14%, 46.3% vs 37.0%, p=0.031) cancers and more NPBC who received chemotherapy (40.7% vs 21.3%, p<0.001). There was no significant difference in 10-year DFS and OS between US detected vs MG-detected NPBC, DCIS and invasive NPBC. For all NPBC and the US detected NPBC, the common DFS-predictors included pT, pN, p53 and bilateral cancers. CONCLUSION: US could detect more invasive, node-positive, multifocal NPBC in hospital-based asymptomatic Chinese female, who could achieve comparable 10-year DFS and OS as MG-detected NPBC. US would not delay early detection of NPBC with improved cost-effectiveness, thus could serve as the feasible initial imaging modality in hospital-based opportunistic screening among Chinese women. PMID- 27689336 TI - Keratin 18-deficiency results in steatohepatitis and liver tumors in old mice: A model of steatohepatitis-associated liver carcinogenesis. AB - : Backround: Steatohepatitis (SH)-associated liver carcinogenesis is an increasingly important issue in clinical medicine. SH is morphologically characterized by steatosis, hepatocyte injury, ballooning, hepatocytic cytoplasmic inclusions termed Mallory-Denk bodies (MDBs), inflammation and fibrosis. RESULTS: 17-20-months-old Krt18-/- and Krt18+/- mice in contrast to wt mice spontaneously developed liver lesions closely resembling the morphological spectrum of human SH as well as liver tumors. The pathologic alterations were more pronounced in Krt18-/- than in Krt18+/- mice. The frequency of liver tumors with male predominance was significantly higher in Krt18-/- compared to age matched Krt18+/- and wt mice. Krt18-deficient tumors in contrast to wt animals displayed SH features and often pleomorphic morphology. aCGH analysis of tumors revealed chromosomal aberrations in Krt18-/- liver tumors, affecting loci of oncogenes and tumor suppressor genes. MATERIALS AND METHODS: Livers of 3-, 6-, 12 and 17-20-months-old aged wild type (wt), Krt18+/- and Krt18-/- (129P2/OlaHsd background) mice were analyzed by light and immunofluorescence microscopy as well as immunohistochemistry. Liver tumors arising in aged mice were analyzed by array comparative genomic hybridization (aCGH). CONCLUSIONS: Our findings show that K18 deficiency of hepatocytes leads to steatosis, increasing with age, and finally to SH. K18 deficiency and age promote liver tumor development in mice, frequently on the basis of chromosomal instability, resembling human HCC with stemness features. PMID- 27689337 TI - p53 in the mitochondria, as a trans-acting protein, provides error-correction activities during the incorporation of non-canonical dUTP into DNA. AB - Mutations in mitochondrial DNA is an outcome of errors produced by DNA polymerase gamma during replication and failure of the repair mechanism. Misincorporation of non-canonical dUTP leads to mutagenesis or apoptosis, and may contribute to the cytotoxic effects of 5'-fluorouracil chemotherapy. Tumor suppressor p53 protein in the mitochondria displays physical and functional interactions with mitochondrial DNA and polymerase gamma, and by its intrinsic 3'->5' exonuclease activity can diminish the polymerization errors. Here we demonstrate the impact of p53 on incorporation of uracil into DNA examined with mitochondrial fractions, as the source of polymerase gamma. p53 in mitochondria facilitates DNA damage repair functions resulting from uracil-DNA misincorporation. Our biochemical studies revealed that the procession of U:A and mismatched U:G lesions enhances in the presence of recombinant or endogenous cytoplasmic p53. p53 in mitochondria can function as an exonuclease/proofreader for polymerase gamma by either decreasing the incorporation of non-canonical dUTP into DNA or by promoting the excision of incorporated nucleotide from nascent DNA, thus expanding the spectrum of DNA damage sites exploited for proofreading as a trans-acting protein. The data suggest that p53 may contribute to defense of the cells from consequences of dUTP misincorporation in both normal and tumor cells. PMID- 27689335 TI - Co-application of canavanine and irradiation uncouples anticancer potential of arginine deprivation from citrulline availability. AB - The moderate anticancer effect of arginine deprivation in clinical trials has been linked to an induced argininosuccinate synthetase (ASS1) expression in initially ASS1-negative tumors, and ASS1-positive cancers are anticipated as non responders. Our previous studies indicated that arginine deprivation and low doses of the natural arginine analog canavanine can enhance radioresponse. However, the efficacy of the proposed combination in the presence of extracellular citrulline, the substrate for arginine synthesis by ASS1, remains to be elucidated, in particular for malignant cells with positive and/or inducible ASS1 as in colorectal cancer (CRC). Here, the physiological citrulline concentration of 0.05 mM was insufficient to overcome cell cycle arrest and radiosensitization triggered by arginine deficiency. Hyperphysiological citrulline (0.4 mM) did not entirely compensate for the absence of arginine and significantly decelerated cell cycling. Similar levels of canavanine-induced apoptosis were detected in the absence of arginine regardless of citrulline supplementation both in 2-D and advanced 3-D assays, while normal colon epithelial cells in organoid/colonosphere culture were unaffected. Notably, canavanine tremendously enhanced radiosensitivity of arginine-starved 3-D CRC spheroids even in the presence of hyperphysiological citrulline. We conclude that the novel combinatorial targeting strategy of metabolic-chemo-radiotherapy has great potential for the treatment of malignancies with inducible ASS1 expression. PMID- 27689338 TI - Promoter methylation patterns of ABCB1, ABCC1 and ABCG2 in human cancer cell lines, multidrug-resistant cell models and tumor, tumor-adjacent and tumor distant tissues from breast cancer patients. AB - Overexpression of ABCB1, ABCC1 and ABCG2 in tumor tissues is considered a major cause of limited efficacy of anticancer drugs. Gene expression of ABC transporters is regulated by multiple mechanisms, including changes in the DNA methylation status. Most of the studies published so far only report promoter methylation levels for either ABCB1 or ABCG2, and data on the methylation status for ABCC1 are scarce. Thus, we determined the promoter methylation patterns of ABCB1, ABCC1 and ABCG2 in 19 human cancer cell lines. In order to contribute to the elucidation of the role of DNA methylation changes in acquisition of a multidrug resistant (MDR) phenotype, we also analyzed the promoter methylation patterns in drug-resistant sublines of the cancer cell lines GLC-4, SW1573, KB-3 1 and HL-60. In addition, we investigated if aberrant promoter methylation levels of ABCB1, ABCC1 and ABCG2 occur in tumor and tumor-surrounding tissues from breast cancer patients.Our data indicates that hypomethylation of the ABCC1 promoter is not cancer type-specific but occurs in cancer cell lines of different origins. Promoter methylation was found to be an important mechanism in gene regulation of ABCB1 in parental cancer cell lines and their drug-resistant sublines. Overexpression of ABCC1 in MDR cell models turned out to be mediated by gene amplification, not by changes in the promoter methylation status of ABCC1. In contrast to the promoters of ABCC1 and ABCG2, the promoter of ABCB1 was significantly higher methylated in tumor tissues than in tumor-adjacent and tumor distant tissues from breast cancer patients. PMID- 27689340 TI - Preferential 5-Methylcytosine Oxidation in the Linker Region of Reconstituted Positioned Nucleosomes by Tet1 Protein. AB - Tet (ten-eleven translocation) family proteins oxidize 5-methylcytosine (mC) to 5 hydroxymethylcytosine (hmC), 5-formylcytosine (fC), and 5-carboxycytosine (caC), and are suggested to be involved in the active DNA demethylation pathway. In this study, we reconstituted positioned mononucleosomes using CpG-methylated 382 bp DNA containing the Widom 601 sequence and recombinant histone octamer, and subjected the nucleosome to treatment with Tet1 protein. The sites of oxidized methylcytosine were identified by bisulfite sequencing. We found that, for the oxidation reaction, Tet1 protein prefers mCs located in the linker region of the nucleosome compared with those located in the core region. PMID- 27689341 TI - Extracellular mycosynthesis of silver nanoparticles and their microbicidal activity. AB - Myconanotechnology, a combination of mycology and nanotechnology that deals with the synthesis of nanoparticles using fungi or their metabolites, has great potential in the area of agriculture owing to the high surface-to-volume ratio and excellent biomedical, electronic, mechanical and physicochemical properties of these myconanoparticles. Extracellular mycosynthesis of Aspergillus flavus (KF934407) silver nanoparticles (AgNPs) was performed, which were produced by redox reaction. Furthermore, the extracellular synthesised AgNPs were characterised by ultraviolet/visible spectrophotometry, differential light scattering (DLS) and transmission electron microscopy. The bactericidal and fungicidal actions of synthesised silver myconanoparticles (myco-AgNPs) were studied against pathogenic bacteria and fungi. The formulated myco-AgNPs were spherical in shape, with a size in the range of 50nm and DLS at an intensity of 107.8nm. The myco-AgNPs showed effective antimicrobial properties against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Trichoderma spp. at high concentrations. In conclusion, AgNPs have a prolonged microbicidal effect as a result of continuous release of Ag+ at sufficient concentrations. Thus, A. flavus-based myco-AgNPs have the potential to be used as a non-toxic and cheap antimicrobial agent against various pathogenic bacteria and fungi. PMID- 27689342 TI - Syntheses and Structures of Xenon Trioxide Alkylnitrile Adducts. AB - The potent oxidizer and highly shock-sensitive binary noble-gas oxide XeO3 interacts with CH3 CN and CH3 CH2 CN to form O3 XeNCCH3 , O3 Xe(NCCH3 )2 , O3 XeNCCH2 CH3 , and O3 Xe(NCCH2 CH3 )2 . Their low-temperature single-crystal X-ray structures show that the xenon atoms are consistently coordinated to three donor atoms, which results in pseudo-octahedral environments around the xenon atoms. The adduct series provides the first examples of a neutral xenon oxide bound to nitrogen bases. Raman frequency shifts and Xe-N bond lengths are consistent with complex formation. Energy-minimized gas-phase geometries and vibrational frequencies were obtained for the model compounds O3 Xe(NCCH3 )n (n=1-3) and O3 Xe(NCCH3 )n ?[O3 Xe(NCCH3 )2 ]2 (n=1, 2). Natural bond orbital (NBO), quantum theory of atoms in molecules (QTAIM), electron localization function (ELF), and molecular electrostatic potential surface (MEPS) analyses were carried out to further probe the nature of the bonding in these adducts. PMID- 27689339 TI - Circulating immune cells in multiple sclerosis. AB - Circulating T and B lymphocytes contribute to the pathogenesis of the neuroinflammatory autoimmune disease, multiple sclerosis (MS). Further progress in the development of MS treatments is dependent upon a greater understanding of the immunological disturbances that underlie the disease. Analyses of circulating immune cells by flow cytometry have revealed MS-associated alterations in the composition and function of T and B cell subsets, including temporal changes associated with disease activity. Disturbances in circulating immune populations reflect those observed in the central nervous system and include skewing towards proinflammatory CD4+ and CD8+ T cells and B cells, greater proportions of follicular T helper cells and functional defects in the corresponding T and B regulatory subsets. Utilizing the analytical power of modern flow cytometers, researchers are now well positioned to monitor immunological changes associated with disease activity or intervention, describe immunological signatures with predictive value and identify targets for therapeutic drug development. This review discusses the contribution of various T and B lymphocyte subsets to MS pathogenesis, provides current and relevant phenotypical descriptions to assist in experimental design and highlights areas of future research. PMID- 27689343 TI - A serum metabolomics-driven approach predicts orange juice consumption and its impact on oxidative stress and inflammation in subjects from the BIONAOS study. AB - SCOPE: To identify biomarkers of orange juice (OJ) consumption containing different doses of polyphenols and to determine its impact on oxidative stress and inflammation using an untargeted metabolomics analysis. METHODS AND RESULTS: Thirty subjects aged 22-63 years from the BIONAOS study consumed a normal polyphenol OJ (NPJ) or a high-polyphenol OJ (HPJ) (299 or 745 mg/L, respectively) for 12 weeks in a randomized, parallel, double-blind study. UHPLC-MS, univariate and multivariate statistical analysis and ROC curves were used to design biomarkers of consumption in serum. We propose betonicine, stachydrine, methyl glucopyranoside (alpha+beta), dihydroferulic acid and galactonate as a new metabolic signature to distinguish the intake of OJ with a different polyphenol content. Changes in metabolites related to OJ, oxidative stress and inflammation were observed. After HPJ consumption, the serum levels of hydroxyoctadecadienoic acid (9-HODE+13-HODE) and dihydroxyoctadecanoic acid (12,13-DiHOME and 9,10 DiHOME) decreased, whereas levels of 12-hydroxyeicosatetraenoic acid (12-HETE) increased. 5-HETE increased after the NPJ intervention exclusively. CONCLUSION: We designed a new panel of biomarkers to differentiate the intake of OJs containing different doses of polyphenols. On the other hand, the consumption of an OJ with a high content of flavanones improved oxidative stress and inflammatory biomarkers. PMID- 27689344 TI - Evaluation of acute traumatic coagulopathy in dogs and cats following blunt force trauma. AB - OBJECTIVE: To evaluate the presence of acute traumatic coagulopathy (ATC) in dogs and cats following blunt trauma and to relate coagulation variables with injury severity and admission variables. DESIGN: Prospective, single center, observational study from 2013 to 2014. SETTING: Urban private referral hospital. ANIMALS: Eighteen and 19 client-owned dogs and cats, respectively, sustaining blunt trauma within 8 hours of presentation without prior resuscitation; 17 healthy staff and client-owned control cats METHODS: Blood samples were collected upon presentation for measurement of blood gas, lactate, blood glucose, ionized calcium, PCV, total plasma protein, prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, platelet count, and thromboelastography. RESULTS: ATC was diagnosed in 1 dog and 1 cat on presentation. Hypercoagulability was documented in 4/18 (22%) of dogs and 1/19 (5.3%) of cats. In dogs, prolongation of PT (P = 0.018), aPTT (P = 0.013) and decrease in maximum amplitude (MA) (P = 0.027) were significantly associated with injury severity as measured by the animal trauma triage (ATT) score. In cats, PT, aPTT, MA, and clot strength (G) were not associated with injury severity. In cats, increasing blood glucose and lactate were significantly associated with decreasing MA (P = 0.041, P = 0.031) and G (P = 0.014, P = 0.03). In both dogs (P = 0.002) and cats (P = 0.007), fibrinogen concentration was significantly correlated with G. CONCLUSIONS: ATC is rare in minimally injured dogs and cats following blunt trauma. In dogs, ATT score is significantly associated with PT, aPTT, and MA, suggesting an increased risk of ATC in more severely injured animals. ATT score does not appear to predict coagulopathies in cats. Future studies including more severely injured animals are warranted to better characterize coagulation changes associated with blunt trauma. PMID- 27689345 TI - Ghrelin is a possible new predictor associated with executive function in patients with type 2 diabetes mellitus. AB - AIMS/INTRODUCTION: The aim of the present research was to study the ghrelin level, executive function and their possible association in patients with type 2 diabetes mellitus. MATERIALS AND METHODS: A total of 370 people were recruited between March 2015 and March 2016 in this study. Among them, 212 participants were patients with type 2 diabetes mellitus and 158 participants were included as the control group. Their blood sample was analyzed for the level of ghrelin and other clinical indexes. Cognitive function was measured by the Montreal Cognitive Assessment, and executive function was evaluated by the Wisconsin Card Sorting Test. RESULTS: In the type 2 diabetes mellitus group, age, years of education, duration of diabetes, fasting blood glucose, glycated hemoglobin, hypertension and waist-to-hip ratio were correlated with total Montreal Cognitive Assessment scores. No association was found between ghrelin level and total Montreal Cognitive Assessment score in patients with type 2 diabetes mellitus. However, ghrelin was found to be a significant predictor for executive function impairment measured by the Wisconsin Card Sorting Test in patients with type 2 diabetes mellitus. CONCLUSIONS: The level of serum ghrelin might be a biomarker of executive function and become a strong predictor of executive function impairment in patients with type 2 diabetes mellitus. Ghrelin might have a potential protective effect against cognitive function impairment in type 2 diabetes patients.

AB - The heterometallic complexes (NH4 )2 [Co(H2 O)6 ]2 [V10 O28 ]?4 H2 O (1) and (NH4 )2 [Co(H2 O)5 (beta-HAla)]2 [V10 O28 ]?4 H2 O (2) have been synthesized and used for the preparation of mixed oxides as catalysts for water oxidation. Thermal decomposition of 1 and 2 at relatively low temperatures (<500 degrees C) leads to the formation of the solid mixed oxides CoV2 O6 /V2 O5 (3) and Co2 V2 O7 /V2 O5 (4). The complexes (1, 2) and heterogeneous materials (3, 4) act as catalysts for photoinduced water oxidation. A modification of the thermal decomposition procedure allowed the deposition of mixed metal oxides (MMO) on a mesoporous TiO2 film. The electrodes containing Co/V MMOs in TiO2 films were used for electrocatalytic water oxidation and showed good stability and sustained anodic currents of about 5 mA cm-2 at 1.72 V versus relative hydrogen electrode (RHE). This method of functionalizing TiO2 films with MMOs at relatively low temperatures (<500 degrees C) can be used to produce other oxides with different functionality for applications in, for example, artificial photosynthesis.

AB - A variable stiffness fiber made of silicone and low melting point alloys quickly becomes >700 times softer and >400 times more deformable when heated above 62 degrees C.

PMID- 27689348 TI - Neither nefopam nor acetaminophen can be used as postoperative analgesics in a rat model of ischemic stroke. AB - : Analgesics such as opioid agonists are usually not given during the postoperative phase of experimental stroke because they are susceptible to interfere with the evaluation of neuroprotective therapies. Here, we investigate the potential of acetaminophen and nefopam, two nonopioid analgesic drugs, to exert an analgesic effect without inducing neuroprotection in a murine model of ischemic stroke. We demonstrate that acetaminophen (200 mg/kg, PO) induces a significant decrease in the infarct volume, particularly in the cortex (VEHICLE: 200.1 mm3 vs. ACETAMINOPHEN: 140.9 mm3 , P < 0.05), while nefopam (2, 20 or 40 mg/kg, IM), administered at the end of middle cerebral artery occlusion (MCAO), do not influence the infarct size (VEHICLE: 268.6 mm3 vs. NEFOPAM 2: 248.8 mm3 , NEFOPAM 20: 250.6 mm3 and NEFOPAM 40: 215.9 mm3 , P > 0.05). Moreover, we find that nefopam administration (20 mg/kg, IM) in the acute postoperative phase do not change the level of neuroprotection induced by MK801 (3 mg/kg, IV), a well known neuroprotectant (VEHICLE: 268.6 mm3 vs. MK801: 194.4 mm3 and vs. MK801 + NEFOPAM 20: 195.2 mm3 ). On the other hand, although nefopam induces analgesia in healthy animals, it is not the case when administered during MCAO (behavior scores at 5 min: HEALTHY: 2.1 vs. HEALTHY + NEFOPAM 20: 0.6, P < 0.5; IR: 0.40 vs. IR + NEFOPAM 20: 0.67, P > 0.05). Our data suggest that neither acetaminophen nor nefopam can be used as analgesic agents to meet the needs of limiting rodent pain and distress during experimental stroke surgery.

AB - The Na2.55V6O16 structure is a promising material for sodium ion batteries due to a significant capacity and stability at high current rates, but its cycle stability for Na application is significantly lower than that obtained with Li (de-)insertion. In this work, we present the results of density functional theory (DFT) calculations on the structural and electronic properties of Na2+x V6O16 compounds up to x = 2. As x increases, we evidence a strong deformation of the tetrahedral sites occupied by sodium ions, leading to new highly stable sites for these inserted ions at x = 2. Comparing with Li4V6O16, we demonstrate that the stability of these new Na sites can be attributed to the electrostatic interactions between sodium ions and atoms of the host structure, the evolution of the oxidation degree of Vanadium atoms being another indicator of such effects.

AB - This study was carried out to investigate the kinetics of coffee industrial residue (CIR) pyrolysis, the effect of pyrolysis factors on yield of bio-oil component and components separation of bio-oil. The kinetics of CIR pyrolysis was analyzed using distributed activation energy model (DAEM), based on the experiments in thermogravimetric analyzer (TGA), and it indicated that the average of activation energy (E) is 187.86kJ.mol-1. The bio-oils were prepared from CIR pyrolysis in vacuum tube furnace, and its components were determined by gas chromatography/mass spectrometry (GC-MS). Among pyrolysis factors, pyrolysis temperature is the most influential factor on components yield of bio-oil, directly concerned with the volatilization and yield of components (palmitic acid, linoleic acid, oleic acid, octadecanoic acid and caffeine). Furthermore, a new method (sequencing temperature-raising pyrolysis) was put forward and applied to the components separation of bio-oil. Based on experiments, a solution of components separation of bio-oil was come out. PMID- 27689351 TI - Enhanced lipid production in thermo-tolerant mutants of Chlorella pyrenoidosa NCIM 2738. AB - The present study aimed to develop thermo-tolerant mutants of Chlorella pyrenoidosa NCIM 2738 for high lipids production. For this, ethyl methane sulfonate was used, which generated two effective thermo-tolerant mutants, M18 and M24 of Chlorella pyrenoidosa NCIM 2738, capable of surviving at temperature up to 47 degrees C and showing improved lipid and biomass yields. They showed 59.62% and 50.75% increase, respectively in lipid content compared to wild type at 30 degrees C, which could not grow at temperature above 35 degrees C. The novelty of this study lied in incorporation of PAM Flurometry with mutagenesis to generate thermo-tolerant mutants of C. pyrenoidosa and investigating the reasons for increased yields of mutants at cellular and photosynthetic levels with the aim to use them for commercial biodiesel production. PMID- 27689352 TI - Shift in microbial community structure of anaerobic side-stream reactor in response to changes to anaerobic solid retention time and sludge interchange ratio. AB - A laboratory scale nutrient removal activated sludge system coupled with an anaerobic side-stream reactor was operated for 300 days treating real urban wastewater. A significant decrease in sludge production was obtained increasing the anaerobic solid retention time (SRTASSR) and decreasing the sludge interchange ratio (IR). In this study, the microbial community structure was analyzed and compared with the sludge reduction performance. Quantitative polymerase chain reaction analyses encoding 16 ribosomal RNA and functional genes revealed a wide diversity of phylogenetic groups in each experimental period, resulting from long solids retention time and recirculation of sludge under aerobic, anoxic and anaerobic conditions. However, decreasing SRTASSR from 10 to 2.5d and increasing IR from 27 to 100%, an increasing selection of both fermenting bacteria able to release extracellular polymeric substances and hydrolyze organic matter and slow growing bacteria involved in nutrient removal were detected and linked to the sludge reduction mechanisms. PMID- 27689353 TI - Rapid and visual Chlamydia trachomatis detection using loop-mediated isothermal amplification and hydroxynaphthol blue. AB - : We developed an assay comprising crude DNA lysis by simple heat treatment coupled loop-mediated isothermal amplification with hydroxynaphthol blue for Chlamydia trachomatis detection (petty patent pending), and evaluated the developed assay for its feasibility as a one-step point-of-care detection on 284 endocervical swab specimens from clinically symptomatic C. trachomatis and healthy subjects. This assay is sensitive to 0.04 pg of ompA, specific with six primers targeting C. trachomatis ompA region, rapid (45 min total assay time), inexpensive (approx. 3 USD/reaction), does not require sophisticated instrumentation, and has comparable assay effectiveness (95% specificity, 90-100% sensitivity) to bacterial DNA isolation by a commercial kit coupled with polymerase chain reaction and gel electrophoresis (98-100% specificity, 87-100% sensitivity) based on the clinical samples test. The test result could be read by naked eye through the colour change from violet (negative) to sky blue (positive) for C. trachomatis-infected specimens. Further, this assay uses all safe chemical reagents and is hence safe to the users. SIGNIFICANCE AND IMPACT OF THE STUDY: Chlamydia trachomatis is the major bacterial sexually transmitted disease worldwide. The clinical symptoms are broad, and chronic C. trachomatis infections could lead to blindness, ectopic pregnancy, sterility in males and females, and a higher risk of the development of cervical cancer. The result indicates the potential usefulness of our crude DNA lysis coupled loop-mediated isothermal amplification with hydroxynaphthol blue for a simple, rapid, specific, sensitive and cost-effective assay for C. trachomatis detection from suspected specimens. This assay offers an alternative in the clinical diagnosis of C. trachomatis in resource-limited health-care facilities and clinical laboratories in developing countries, and in field tests. PMID- 27689354 TI - Suitability Analysis and Projected Climate Change Impact on Banana and Coffee Production Zones in Nepal. AB - The Government of Nepal has identified opportunities in agricultural commercialization, responding to a growing internal demand and expansion of export markets to reduce the immense trade deficit. Several cash crops, including coffee and bananas, have been identified in the recently approved Agriculture Development Strategy. Both of these crops have encouraged smallholder farmers to convert their subsistence farming practices to more commercial cultivation. Identification of suitable agro-ecological zones and understanding climate related issues are important for improved production and livelihoods of smallholder farmers. Here, the suitability of coffee and banana crops is analyzed for different agro-ecological zones represented by Global Environmental Stratification (GEnS). Future shifts in these suitability zones are also predicted. Plantation sites in Nepal were geo-referenced and used as input in species distribution modelling. The multi-model ensemble model suggests that climate change will reduce the suitable growing area for coffee by about 72% across the selected emission scenarios from now to 2050. Impacts are low for banana growing, with a reduction in suitability by about 16% by 2050. Bananas show a lot of potential for playing an important role in Nepal as a sustainable crop in the context of climate change, as this study indicates that the amount of area suited to banana growing will grow by 40% by 2050. Based on our analysis we recommend possible new locations for coffee plantations and one method for mitigating climate change-related problems on existing plantations. These findings are expected to support planning and policy dialogue for mitigation and support better informed and scientifically based decision-making relating to these two crops. PMID- 27689355 TI - Apo AIV and Citrulline Plasma Concentrations in Short Bowel Syndrome Patients: The Influence of Short Bowel Anatomy. AB - INTRODUCTION: Parenteral nutrition (PN) dependence in short bowel syndrome (SBS) patients is linked to the functionality of the remnant small bowel (RSB). Patients may wean off PN following a period of intestinal adaptation that restores this functionality. Currently, plasma citrulline is the standard biomarker for monitoring intestinal functionality and adaptation. However, available studies reveal that the relationship the biomarker with the length and function of the RSB is arguable. Thus, having additional biomarkers would improve pointing out PN weaning. AIM: By measuring concomitant changes in citrulline and the novel biomarker apolipoprotein AIV (Apo AIV), as well as taking into account the anatomy of the RSB, this exploratory study aims to a better understanding of the intestinal adaptation process and characterization of the SBS patients under PN. METHODS: Thirty four adult SBS patients were selected and assigned to adapted (aSBS) and non-adapted (nSBS) groups after reconstructive surgeries. Remaining jejunum and ileum lengths were recorded. The aSBS patients were either on an oral diet (ORAL group), those with intestinal insufficiency, or on oral and home parenteral nutrition (HPN group), those with chronic intestinal failure. Apo AIV and citrulline were analyzed in plasma samples after overnight fasting. An exploratory ROC analysis using citrulline as gold standard was performed. RESULTS: Biomarkers, Apo AIV and citrulline showed a significant correlation with RSBL in aSBS patients. In jejuno-ileocolic patients, only Apo AIV correlated with RSBL (rb = 0.54) and with ileum length (rb = 0.84). In patients without ileum neither biomarker showed any correlation with RSBL. ROC analysis indicated the Apo AIV cut-off value to be 4.6 mg /100 mL for differentiating between the aSBS HPN and ORAL groups. CONCLUSIONS: Therefore, in addition to citrulline, Apo AIV can be set as a biomarker to monitor intestinal adaptation in SBS patients. As short bowel anatomy is shown to influence citrulline and Apo AIV plasma values, both biomarkers complement each other furnishing a new insight to manage PN dependence. PMID- 27689356 TI - Potential Cost-Effectiveness of RSV Vaccination of Infants and Pregnant Women in Turkey: An Illustration Based on Bursa Data. AB - BACKGROUND: Worldwide, respiratory syncytial virus (RSV) is considered to be the most important viral cause of respiratory morbidity and mortality among infants and young children. Although no active vaccine is available on the market yet, there are several active vaccine development programs in various stages. To assess whether one of these vaccines might be a future asset for national immunization programs, modeling the costs and benefits of various vaccination strategies is needed. OBJECTIVES: To evaluate the potential cost-effectiveness of RSV vaccination of infants and/or pregnant women in Turkey. METHODS: A multi cohort static Markov model with cycles of one month was used to compare the cost effectiveness of vaccinated cohorts versus non-vaccinated cohorts. The 2014 Turkish birth cohort was divided by twelve to construct twelve monthly birth cohorts of equal size (111,459 new-borns). Model input was based on clinical data from a multicenter prospective study from Bursa, Turkey, combined with figures from the (inter)national literature and publicly available data from the Turkish Statistical Institute (TUIK). Incremental cost-effectiveness ratios (ICERs) were expressed in Turkish Lira (TL) per quality-adjusted life year (QALY) gained. RESULTS: Vaccinating infants at 2 and 4 months of age would prevent 145,802 GP visits, 8,201 hospitalizations and 48 deaths during the first year of life, corresponding to a total gain of 1650 QALYs. The discounted ICER was estimated at 51,969 TL (26,220 US $ in 2013) per QALY gained. Vaccinating both pregnant women and infants would prevent more cases, but was less attractive from a pure economic point of view with a discounted ICER of 61,653 TL (31,106 US $ in 2013) per QALY. Vaccinating only during pregnancy would result in fewer cases prevented than infant vaccination and a less favorable ICER. CONCLUSION: RSV vaccination of infants and/or pregnant women has the potential to be cost-effective in Turkey. Although using relatively conservative assumptions, all evaluated strategies remained slightly below the threshold of 3 times the GDP per capita. PMID- 27689359 TI - Searching for trust. PMID- 27689358 TI - Allatostatin A Signalling in Drosophila Regulates Feeding and Sleep and Is Modulated by PDF. AB - Feeding and sleep are fundamental behaviours with significant interconnections and cross-modulations. The circadian system and peptidergic signals are important components of this modulation, but still little is known about the mechanisms and networks by which they interact to regulate feeding and sleep. We show that specific thermogenetic activation of peptidergic Allatostatin A (AstA)-expressing PLP neurons and enteroendocrine cells reduces feeding and promotes sleep in the fruit fly Drosophila. The effects of AstA cell activation are mediated by AstA peptides with receptors homolog to galanin receptors subserving similar and apparently conserved functions in vertebrates. We further identify the PLP neurons as a downstream target of the neuropeptide pigment-dispersing factor (PDF), an output factor of the circadian clock. PLP neurons are contacted by PDF expressing clock neurons, and express a functional PDF receptor demonstrated by cAMP imaging. Silencing of AstA signalling and continuous input to AstA cells by tethered PDF changes the sleep/activity ratio in opposite directions but does not affect rhythmicity. Taken together, our results suggest that pleiotropic AstA signalling by a distinct neuronal and enteroendocrine AstA cell subset adapts the fly to a digestive energy-saving state which can be modulated by PDF. PMID- 27689357 TI - Fis Is Essential for Yersinia pseudotuberculosis Virulence and Protects against Reactive Oxygen Species Produced by Phagocytic Cells during Infection. AB - All three pathogenic Yersinia species share a conserved virulence plasmid that encodes a Type 3 Secretion System (T3SS) and its associated effector proteins. During mammalian infection, these effectors are injected into innate immune cells, where they block many bactericidal functions, including the production of reactive oxygen species (ROS). However, Y. pseudotuberculosis (Yptb) lacking the T3SS retains the ability to colonize host organs, demonstrating that chromosome encoded factors are sufficient for growth within mammalian tissue sites. Previously we uncovered more than 30 chromosomal factors that contribute to growth of T3SS-deficient Yptb in livers. Here, a deep sequencing-based approach was used to validate and characterize the phenotype of 18 of these genes during infection by both WT and plasmid-deficient Yptb. Additionally, the fitness of these mutants was evaluated in immunocompromised mice to determine whether any genes contributed to defense against phagocytic cell restriction. Mutants containing deletions of the dusB-fis operon, which encodes the nucleoid associated protein Fis, were markedly attenuated in immunocompetent mice, but were restored for growth in mice lacking neutrophils and inflammatory monocytes, two of the major cell types responsible for restricting Yersinia infection. We determined that Fis was dispensable for secretion of T3SS effectors, but was essential for resisting ROS and regulated the transcription of several ROS responsive genes. Strikingly, this protection was critical for virulence, as growth of DeltadusB-fis was restored in mice unable to produce ROS. These data support a model in which ROS generated by neutrophils and inflammatory monocytes that have not been translocated with T3SS effectors enter bacterial cells during infection, where their bactericidal effects are resisted in a Fis-dependent manner. This is the first report of the requirement for Fis during Yersinia infection and also highlights a novel mechanism by which Yptb defends against ROS in mammalian tissues. PMID- 27689360 TI - Clinical significance and prognostic value of TRIM24 expression in esophageal squamous cell carcinoma. AB - Tripartite motif-containing 24 (TRIM24), a member of the transcription intermediary factor 1 family, is defined as a co-regulator with several nuclear receptors, such as RARalpha. TRIM24 has been reported to be involved in many cancers. In this study, we aimed to investigate the expression pattern and prognostic significance of TRIM24 and its relationship with RARalpha in esophageal squamous cell cancer (ESCC). Both mRNA and protein expression levels of TRIM24 were found to be significantly decreased in ESCC, as judged by qRT-PCR and western blot. Immunohistochemistry staining shows that the reduced TRIM24 protein is associated with lymph node metastasis (P=0.024), advance pathological TNM (pTNM) stage (P=0.046) and recurrence/metastasis (P=0.001). Upregulated TRIM24 protein predicts longer overall survival and disease-free survival (both P<0.001) and is an independent predictor for good prognosis (HR, 0.519; 95%CI, 0.341-0.788; P=0.002). TRIM24 expression has been proven remarkably to improve prediction of survival of pTNM stage in ESCC patients, especially in stage I and II. However, no significant relationship was found between TRIM24 and RARalpha expression levels. In conclusion, reduced TRIM24 protein is associated with poor survival in ESCC patients, suggesting TRIM24 protein is a potential prognostic biomarker for ESCC. PMID- 27689361 TI - The Edge of Stability: Response Times and Delta Oscillations in Balanced Networks. AB - The standard architecture of neocortex is a network with excitation and inhibition in closely maintained balance. These networks respond fast and with high precision to their inputs and they allow selective amplification of patterned signals. The stability of such networks is known to depend on balancing the strengths of positive and negative feedback. We here show that a second condition is required for stability which depends on the relative strengths and time courses of fast (AMPA) and slow (NMDA) currents in the excitatory projections. This condition also determines the response time of the network. We show that networks which respond quickly to an input are necessarily close to an oscillatory instability which resonates in the delta range. This instability explains the existence of neocortical delta oscillations and the emergence of absence epilepsy. Although cortical delta oscillations are a network-level phenomenon, we show that in non-pathological networks, individual neurons receive sufficient information to keep the network in the fast-response regime without sliding into the instability. PMID- 27689362 TI - Stochastic Optimization for an Analytical Model of Saltwater Intrusion in Coastal Aquifers. AB - The present study implements a stochastic optimization technique to optimally manage freshwater pumping from coastal aquifers. Our simulations utilize the well known sharp interface model for saltwater intrusion in coastal aquifers together with its known analytical solution. The objective is to maximize the total volume of freshwater pumped by the wells from the aquifer while, at the same time, protecting the aquifer from saltwater intrusion. In the direction of dealing with this problem in real time, the ALOPEX stochastic optimization method is used, to optimize the pumping rates of the wells, coupled with a penalty-based strategy that keeps the saltwater front at a safe distance from the wells. Several numerical optimization results, that simulate a known real aquifer case, are presented. The results explore the computational performance of the chosen stochastic optimization method as well as its abilities to manage freshwater pumping in real aquifer environments.

PMID- 27689385 TI - High-Efficiency Fog Collector: Water Unidirectional Transport on Heterogeneous Rough Conical Wires. AB - An artificial periodic roughness-gradient conical copper wire (PCCW) can be fabricated by inspiration from cactus spines and wet spider silks. PCCW can harvest fog on periodic points of the conical surface from air and transports the drops for a long distance without external force, which is attributed to dynamic as-released energy generated from drop deformation in drop coalescence, in addition to both gradients of geometric curve (inducing Laplace pressure) and periodic roughness (inducing surface energy difference). It is found that the ability of fog collection can be related to various tilt-angle wires, thus a fog collector with an array system of PCCWs is further designed to achieve a continuous process of efficient water collection. As a result, the effect of water collection on PCCWs is better than previous results. These findings are significant to develop and design materials with water collection and water transport for promising application in fogwater systems to ease the water crisis. PMID- 27689387 TI - Comparative Mammalian Cell Cytotoxicity of Wastewaters for Agricultural Reuse after Ozonation. AB - Reusing wastewater in agriculture is becoming increasingly common, which necessitates disinfection to ensure reuse safety. However, disinfectants can react with wastewater constituents to form disinfection byproducts (DBPs), many of which are toxic and restrict the goal of safe reuse. Our objective was to benchmark the induction of mammalian cell cytotoxicity after ozonation against chlorination for three types of real wastewaters: municipal secondary effluent and two sources of minimally treated swine farm wastewaters. A new method to evaluate samples of suspected high cytotoxicity was devised. For the secondary effluent, ozonation reduced the cytotoxicity by as much as 10 times; chlorination lowered the cytotoxicity only when followed by dechlorination. The swine farm wastewaters were up to 2000 times more cytotoxic than the secondary effluent, and the highest reduction in cytotoxicity was 17 times as achieved by ozonation. These results indicate that secondary effluent is preferred over swine wastewaters for agricultural reuse regardless of the tested disinfectants. Ozonation consistently reduced the cytotoxicity of both the full strength and the organic extracts of all tested wastewaters more than chlorination. The only significant correlation was observed in the secondary wastewater between total haloacetonitriles and cytotoxicity. While the association of reduced toxicity with the modification or reduction of specific compound(s) is unclear, regulated DBPs may not be the primary forcing agents. PMID- 27689386 TI - Copolymer Brush-Based Ultralow-Fouling Biorecognition Surface Platform for Food Safety. AB - Functional polymer coatings that combine the ability to resist nonspecific fouling from complex media with high biorecognition element (BRE) immobilization capacity represent an emerging class of new functional materials for a number of bioanalytical and biosensor technologies for medical diagnostics, security, and food safety. Here, we report on a random copolymer brush surface - poly(CBMAA-ran HPMAA) - providing high BRE immobilization capacity while simultaneously exhibiting ultralow-fouling behavior in complex food media. We demonstrate that both the functionalization and fouling resistance capabilities of such copolymer brushes can be tuned by changing the surface contents of the two monomer units: nonionic N-(2-hydroxypropyl) methacrylamide (HPMAA) and carboxy-functional zwitterionic carboxybetaine methacrylamide (CBMAA). It is demonstrated that the resistance to fouling decreases with the surface content of CBMAA; poly(CBMAA-ran HPMAA) brushes with CBMAA molar content up to 15 mol % maintain excellent resistance to fouling from a variety of homogenized foods (hamburger, cucumber, milk, and lettuce) even after covalent attachment of BREs to carboxy groups of CBMAA. The poly(CBMAA 15 mol %-ran-HPMAA) brushes functionalized with antibodies are demonstrated to exhibit fouling resistance from food samples by up to 3 orders of magnitude better when compared with the widely used low-fouling carboxy functional oligo(ethylene glycol) (OEG)-based alkanethiolate self-assembled monolayers (AT SAMs) and, furthermore, by up to 2 orders of magnitude better when compared with the most successful ultralow-fouling biorecognition coatings - poly(carboxybetaine acrylamide), poly(CBAA). When model SPR detections of food borne bacterial pathogens in homogenized foods are used, it is also demonstrated that the antibody-functionalized poly(CBMAA 15 mol %-ran-HPMAA) brush exhibits superior biorecognition properties over the poly(CBAA). PMID- 27689388 TI - First-in-Class Chemical Probes against Poly(ADP-ribose) Glycohydrolase (PARG) Inhibit DNA Repair with Differential Pharmacology to Olaparib. AB - The enzyme poly(ADP-ribose) glycohydrolase (PARG) performs a critical role in the repair of DNA single strand breaks (SSBs). However, a detailed understanding of its mechanism of action has been hampered by a lack of credible, cell-active chemical probes. Herein, we demonstrate inhibition of PARG with a small molecule, leading to poly(ADP-ribose) (PAR) chain persistence in intact cells. Moreover, we describe two advanced, and chemically distinct, cell-active tool compounds with convincing on-target pharmacology and selectivity. Using one of these tool compounds, we demonstrate pharmacology consistent with PARG inhibition. Further, while the roles of PARG and poly(ADP-ribose) polymerase (PARP) are closely intertwined, we demonstrate that the pharmacology of a PARG inhibitor differs from that observed with the more thoroughly studied PARP inhibitor olaparib. We believe that these tools will facilitate a wider understanding of this important component of DNA repair and may enable the development of novel therapeutic agents exploiting the critical dependence of tumors on the DNA damage response (DDR). PMID- 27689390 TI - NaCl-Dependent Ordering and Dynamic Mechanical Response in Nanoconfined Water. AB - Understanding the dynamics of water under nanoscale confinement is important for biology, geology, tribology, and nanotechnology. In many naturally occurring situations, ions are present in water at various concentrations. Here we report on how the addition of sodium ions alters the squeeze-out behavior of water nanoconfined between a mica surface and silicon oxide tip. We find that Na+ ions enhance molecular ordering and lead to longer mechanical relaxation times. We also observed a critical ion concentration, above which the confined water switches from a viscous to an elastic (solid-like) response at very slow, quasistatic compression speeds. PMID- 27689389 TI - Room-Temperature Micron-Scale Exciton Migration in a Stabilized Emissive Molecular Aggregate. AB - We report 1.6 +/- 1 MUm exciton transport in self-assembled supramolecular light harvesting nanotubes (LHNs) assembled from amphiphillic cyanine dyes. We stabilize LHNs in a sucrose glass matrix, greatly reducing light and oxidative damage and allowing the observation of exciton-exciton annihilation signatures under weak excitation flux. Fitting to a one-dimensional diffusion model, we find an average exciton diffusion constant of 55 +/- 20 cm2/s, among the highest measured for an organic system. We develop a simple model that uses cryogenic measurements of static and dynamic energetic disorder to estimate a diffusion constant of 32 cm2/s, in agreement with experiment. We ascribe large exciton diffusion lengths to low static and dynamic energetic disorder in LHNs. We argue that matrix-stabilized LHNS represent an excellent model system to study coherent excitonic transport. PMID- 27689391 TI - Dependence of Adenine Raman Spectrum on Excitation Laser Wavelength: Comparison between Experiment and Theoretical Simulations. AB - We acquired the Raman spectra of adenine in powder and aqueous phase using excitation lasers with 532, 633, and 785 nm wavelengths for the region between 300 and 1500 cm-1. In comparison to the most distinct peak at 722 cm-1, the peaks between 1200 and 1500 cm-1 exhibited a characteristic increase in cross-section with decreasing excitation wavelength in both phases. This trend can be reproduced by different density functional theory (DFT) calculations for the adenine molecule in the gas phase as well as in the aqueous phase. Furthermore, from the calculation on the pi-stacked dimer, hydrogen-bonded dimer, and trimer, we find that this trend toward excitation laser wavelength is not sensitive to the packing. When comparing the Raman spectra given by different excitation wavelength, one should take care in analyzing the cross-section, and present day DFT calculations are able to capture general trends in the excitation laser wavelength dependence of the Raman activity.

AB - A good catalyst for efficiently controlling NOx emissions often demands strong resistance against alkali poisoning. Although the traditional ion-exchange model, based on acid-base reactions of alkalis with Bronsted acid sites, has been established over the past two decades, it is difficult to be used as a guideline to develop such an alkali-resistant catalyst. Here we establish a self-protection mechanism of deNOx catalysts against alkali poisoning by systematically studying the intrinsic nature of alkali resistance of V2O5/HWO (HWO = hexagonal WO3) that shows excellent resistance to alkali poisoning in selective catalytic reduction of NOx with NH3 (SCR). Synchrotron X-ray diffraction and absorption spectroscopies demonstrate that V2O5/HWO has spatially separated catalytically active sites (CASs) and alkali-trapping sites (ATSs). During the SCR process, ATSs spontaneously trap alkali ions such as K+, even if alkali ions initially block CASs, thus releasing CASs to realize the self-protection against alkali poisoning. X-ray photoelectron spectra coupled with theoretical calculations indicate that the electronic interaction between the alkali ions and ATSs with an energy saving is the driving force of the self-protection. This work provides a strategy to design alkali-resistant deNOx catalysts. PMID- 27689393 TI - Computational Modeling of beta-Secretase 1 (BACE-1) Inhibitors Using Ligand Based Approaches. AB - The binding affinities (IC50) reported for diverse structural and chemical classes of human beta-secretase 1 (BACE-1) inhibitors in literature were modeled using multiple in silico ligand based modeling approaches and statistical techniques. The descriptor space encompasses simple binary molecular fingerprint, one- and two-dimensional constitutional, physicochemical, and topological descriptors, and sophisticated three-dimensional molecular fields that require appropriate structural alignments of varied chemical scaffolds in one universal chemical space. The affinities were modeled using qualitative classification or quantitative regression schemes involving linear, nonlinear, and deep neural network (DNN) machine-learning methods used in the scientific literature for quantitative-structure activity relationships (QSAR). In a departure from tradition, ~20% of the chemically diverse data set (205 compounds) was used to train the model with the remaining ~80% of the structural and chemical analogs used as part of an external validation (1273 compounds) and prospective test (69 compounds) sets respectively to ascertain the model performance. The machine learning methods investigated herein performed well in both the qualitative classification (~70% accuracy) and quantitative IC50 predictions (RMSE ~ 1 log). The success of the 2D descriptor based machine learning approach when compared against the 3D field based technique pursued for hBACE-1 inhibitors provides a strong impetus for systematically applying such methods during the lead identification and optimization efforts for other protein families as well. PMID- 27689394 TI - Water Rearrangements upon Disorder-to-Order Amyloid Transition. AB - Water plays a critical role in governing the intricate balance between chain chain and chain-solvent interactions during protein folding, misfolding, and aggregation. Previous studies have indicated the presence of different types of water in folded (globular) proteins. In this work, using femtosecond and picosecond time-resolved fluorescence measurements, we have characterized the solvation dynamics from ultrafast to ultraslow time scale both in the monomeric state and in the amyloid state of an intrinsically disordered protein, namely kappa-casein. Monomeric kappa-casein adopts a compact disordered state under physiological conditions and is capable of spontaneously aggregating into highly ordered beta-rich amyloid fibrils. Our results indicate that the mobility of "biological water" (type I) gets restrained as a result of conformational sequestration during amyloid formation. Additionally, a significant decrease in the bulk water component with a concomitant increase in the ultraslow component revealed the ordering of trapped interstitial water (type II) upon disorder-to order amyloid transition. Our results provide an experimental underpinning of significant water rearrangements associated with both chain desolvation and water confinement upon amyloid formation.

AB - This study was designed to perform an acceptable prognostic nomogram for acute myeloid leukemia. The clinical data from 311 patients from our institution and 165 patients generated with Cancer Genome Atlas Research Network were reviewed. A prognostic nomogram was designed according to the Cox's proportional hazard model to predict overall survival (OS). To compare the capacity of the nomogram with that of the current prognostic system, the concordance index (C-index) was used to validate the accuracy as well as the calibration curve. The nomogram included 6 valuable variables: age, risk stratifications based on cytogenetic abnormalities, status of FLT3-ITD mutation, status of NPM1 mutation, expression of CD34, and expression of HLA-DR. The C-indexes were 0.71 and 0.68 in the primary and validation cohort respectively, which were superior to the predictive capacity of the current prognostic systems in both cohorts. The nomogram allowed both patients with acute myeloid leukemia and physicians to make prediction of OS individually prior to treatment. PMID- 27689398 TI - Comparative effectiveness of image-guided radiotherapy for non-operated localized esophageal squamous cell carcinoma patients receiving concurrent chemoradiotherapy: A population-based propensity score matched analysis. AB - BACKGROUND: Although concurrent chemoradiotherapy (CCRT) coupled with image guided radiotherapy (IGRT) is associated with a theoretical benefit in non operated localized esophageal squamous cell carcinoma (NOL-ESCC) patients, there is currently no clinical evidence to support this. RESULTS: The study population in the primary analysis comprised 866 patients who were well balanced in terms of their co-variables. The HR for mortality when group A was compared with group B was 0.82 (95% confidence interval, 0.7-0.95). SA revealed that the result was moderately sensitive. MATERIALS AND METHODS: Eligible patients diagnosed between 2008 and 2013 were identified in the Taiwan Cancer Registry. A propensity score matched cohort was constructed [1:1 in groups A (with IGRT) and B (without IGRT)] to balance any observable potential confounders. The hazard ratio (HR) for mortality was compared between groups A and B during the follow-up period. Sensitivity analyses (SA) were performed to evaluate the robustness of the findings regarding the selection of confounders and a potential unobserved confounder. CONCLUSIONS: The current results provide the first clinical evidence that CCRT coupled with IGRT is associated with better overall survival when compared with CCRT without IGRT in NOL-ESCC patients. However, this study should be interpreted with caution given its non-randomized nature and the moderate sensitivity of the data. Further studies are needed to clarify this finding. PMID- 27689397 TI - A CD22-reactive TCR from the T-cell allorepertoire for the treatment of acute lymphoblastic leukemia by TCR gene transfer. AB - CD22 is currently evaluated as a target-antigen for the treatment of B-cell malignancies using chimeric antigen receptor (CAR)-engineered T-cells or monoclonal antibodies (mAbs). CAR- and mAbs-based immunotherapies have been successfully applied targeting other antigens, however, occurrence of refractory disease to these interventions urges the identification of additional strategies. Here, we identified a TCR recognizing the CD22-derived peptide RPFPPHIQL (CD22RPF) presented in human leukocyte antigen (HLA)-B*07:02. To overcome tolerance to self-antigens such as CD22, we exploited the immunogenicity of allogeneic HLA. CD22RPF-specific T-cell clone 9D4 was isolated from a healthy HLA B*07:02neg individual, efficiently produced cytokines upon stimulation with primary acute lymphoblastic leukemia and healthy B-cells, but did not react towards healthy hematopoietic and nonhematopoietic cell subsets, including dendritic cells (DCs) and macrophages expressing low levels of CD22. Gene transfer of TCR-9D4 installed potent CD22-specificity onto recipient CD8+ T-cells that recognized and lysed primary B-cell leukemia. TCR-transduced T-cells spared healthy CD22neg hematopoietic cell subsets but weakly lysed CD22low-expressing DCs and macrophages. CD22-specific TCR-engineered T-cells could form an additional immunotherapeutic strategy with a complementary role to CAR- and antibody-based interventions in the treatment of B-cell malignancies. However, CD22 expression on non-B-cells may limit the attractiveness of CD22 as target antigen in cellular immunotherapy. PMID- 27689399 TI - Epigenetic silencing of tumor suppressor long non-coding RNA BM742401 in chronic lymphocytic leukemia. AB - BM742401 is a tumor suppressor lncRNA downregulated in gastric cancer. As the promoter region and the entire transcript are embedded in a CpG island, we postulated that BM742401 is a tumor suppressor lncRNA inactivated by DNA methylation in chronic lymphocytic leukemia (CLL). The promoter of BM742401 was unmethylated in normal controls including three each of normal bone marrow, peripheral blood buffy coats, and CD19-sorted peripheral B-cells, but methylated in four (57.1%) CLL cell lines. Methylation of BM742401 correlated inversely with expression. In the completely methylated WAC3CD5+ CLL cells, 5-Aza-2' deoxycytidine treatment led to promoter demethylation and re-expression of BM742401 transcript. Functionally, stable overexpression of BM742401 resulted in inhibition of cellular proliferation and enhanced apoptosis through caspase-9 dependent intrinsic but not caspase-8-dependent extrinsic apoptosis pathway, suggesting a tumor suppressor role of BM742401 in CLL. In primary CLL samples, methylation of BM742401 was detected in 43/98 (43.9%) of patients. Moreover, among CLL patients with standard-risk cytogenetic aberrations, methylation of BM742401 correlated with advanced Rai stage (>= stage 2)(P = 0.002). Furthermore, BM742401 methylation was associated with miR-129-2 methylation (P = 0.05). BM742401 is a tumor suppressor lncRNA frequently methylated in CLL. The mechanism of BM742401 as a tumor suppressor warrants further studies. PMID- 27689400 TI - Long noncoding RNA uc.345 promotes tumorigenesis of pancreatic cancer by upregulation of hnRNPL expression. AB - Increasing evidence points to an important functional or regulatory role of long noncoding RNA in cellular processes as well as cancer diseases resulted from the aberrant lncRNA expression. LncRNA could participate in the cancer progression and develop a significant role through the interaction with proteins. In the present study, we report a lncRNA termed uc.345 that is up-regulated in tumor tissues, compared to the corresponding noncancerous tissues. We found that a higher uc.345 expression level was more frequently observed in tissues with increased depth of invasion and advanced TNM tumor node metastasis T stage. Moreover, uc.345 could be used as an independent risk factor for the overall survival (OS) of the pancreatic cancer patients. By employing soft agar assays and tumor xenograft models, we showed that uc.345 could accelerate tumor growth. Further, we discovered that uc.345 could upregulate the hnRNPL expression and that inhibition of (hnRNPL) dampens the tumorigenesis capability of uc.345. Collectively, these results demonstrate that uc.345 functions as an oncogenic lncRNA that promotes tumor progression and serves as a poor predictor for pancreatic cancer patients' overall survival. PMID- 27689401 TI - Expression of the TPalpha and TPbeta isoforms of the thromboxane prostanoid receptor (TP) in prostate cancer: clinical significance and diagnostic potential. AB - The prostanoid thromboxane (TX)A2 plays a central role in haemostasis and is increasingly implicated in cancer progression. TXA2 signals through two T Prostanoid receptor (TP) isoforms termed TPalpha and TPbeta, with both encoded by the TBXA2R gene. Despite exhibiting several functional and regulatory differences, the role of the individual TP isoforms in neoplastic diseases is largely unknown.This study evaluated expression of the TPalpha and TPbeta isoforms in tumour microarrays of the benign prostate and different pathological (Gleason) grades of prostate cancer (PCa). Expression of TPbeta was significantly increased in PCa relative to benign tissue and strongly correlated with increasing Gleason grade. Furthermore, higher TPbeta expression was associated with increased risk of biochemical recurrence (BCR) and significantly shorter disease-free survival time in patients post-surgery. While TPalpha was more variably expressed than TPbeta in PCa, increased/high TPalpha expression within the tumour also trended toward increased BCR and shorter disease-free survival time. Comparative genomic CpG DNA methylation analysis revealed substantial differences in the extent of methylation of the promoter regions of the TBXA2R that specifically regulate expression of TPalpha and TPbeta, respectively, both in benign prostate and in clinically-derived tissue representative of precursor lesions and progressive stages of PCa. Collectively, TPalpha and TPbeta expression is differentially regulated both in the benign and tumourigenic prostate, and coincides with clinical pathology and altered CpG methylation of the TBXA2R gene. Analysis of TPbeta, or a combination of TPalpha/TPbeta, expression levels may have significant clinical potential as a diagnostic biomarker and predictor of PCa disease recurrence. PMID- 27689402 TI - Integration of zebrafish fin regeneration genes with expression data of human tumors in silico uncovers potential novel melanoma markers. AB - Tissue regeneration requires expression of a large, unknown number of genes to initiate and maintain cellular processes such as proliferation, extracellular matrix synthesis, differentiation and migration. A unique model to simulate this process in a controlled manner is the re-growth of the caudal fin of zebrafish after amputation. Within this tissue stem cells differentiate into fibroblasts, epithelial and endothelial cells as well as melanocytes. Many genes implicated in the regeneration process are deregulated in cancer. We therefore undertook a systematic gene expression study to identify genes upregulated during the re growth of caudal fin tissue. By applying a high stringency cut-off value of 4 fold change, we identified 54 annotated genes significantly overexpressed in regenerating blastema. Further bioinformatics data mining studies showed that 22 out of the 54 regeneration genes where overexpressed in melanoma compared to normal skin or other cancers. Whereas the role of TNC (tenascin C) and FN1 (fibronectin 1) in melanoma development is well documented, implication of MARCKS, RCN3, BAMBI, PEA3/ETV4 and the FK506 family members FKBP7, FKBP10 and FKBP11 in melanoma progression is unclear. Corresponding proteins were detected in melanoma tissue but not in normal skin. High expression of FKBP7, DPYSL5 and MDK was significantly associated with poor survival. We discuss a potential role of these novel melanoma genes, which have promising potential as new therapeutic targets or diagnostic markers. PMID- 27689404 TI - In vivo phage display screening for tumor vascular targets in glioblastoma identifies a llama nanobody against dynactin-1-p150Glued. AB - Diffuse gliomas are primary brain cancers that are characterised by infiltrative growth. Whereas high-grade glioma characteristically presents with perinecrotic neovascularisation, large tumor areas thrive on pre-existent vasculature as well. Clinical studies have revealed that pharmacological inhibition of the angiogenic process does not improve survival of glioblastoma patients. Direct targeting of tumor vessels may however still be an interesting therapeutic approach as it allows pinching off the blood supply to tumor cells. Such tumor vessel targeting requires the identification of tumor-specific vascular targeting agents (TVTAs).Here we describe a novel TVTA, C-C7, which we identified via in vivo biopanning of a llama nanobody phage display library in an orthotopic mouse model of diffuse glioma. We show that C-C7 recognizes a subpopulation of tumor blood vessels in glioma xenografts and clinical glioma samples. Additionally, C-C7 recognizes macrophages and activated endothelial cells in atherosclerotic lesions. By using C-C7 as bait in yeast-2-hybrid (Y2H) screens we identified dynactin-1-p150Glued as its binding partner. The interaction was confirmed by co immunostainings with C-C7 and a commercial anti-dynactin-1-p150Glued antibody, and via co-immunoprecipitation/western blot studies. Normal brain vessels do not express dynactin-1-p150Glued and its expression is reduced under anti-VEGF therapy, suggesting that dynactin-1-p150Glued is a marker for activated endothelial cells.In conclusion, we show that in vivo phage display combined with Y2H screenings provides a powerful approach to identify tumor-targeting nanobodies and their binding partners. Using this combination of methods we identify dynactin-1-p150Glued as a novel targetable protein on activated endothelial cells and macrophages. PMID- 27689405 TI - Progressive changes in composition of lymphocytes in lung tissues from patients with non-small-cell lung cancer. AB - Immune cell infiltration is a common feature of many human solid tumors. Innate and adaptative immune systems contribute to tumor immunosurveillance. We investigated whether tumors evade immune surveillance by inducing states of tolerance and/or through the inability of some immune subpopulations to effectively penetrate tumor nests. Immunohistochemistry and flow cytometry analysis were used to study the composition and distribution of immune subpopulations in samples of peripheral blood, tumor tissue (TT), adjacent tumor tissue (ATT), distant non-tumor tissue (DNTT), cancer nests, cancer stroma, and invasive margin in 61 non-small-cell lung cancer (NSCLC) patients. A significantly higher percentage of T and B cells and significantly lower percentage of NK cells were detected in TT than in DNTT. Memory T cells (CD4+CD45RO+, CD8+CD45RO+) and activated T cells (CD8+DR+) were more prevalent in TT. Alongside this immune activation, the percentage of T cells with immunosuppressive activity was higher in TT than in DNTT. B- cells were practically non-existent in tumor nests and were preferentially located in the invasive margin. The dominant NK cell phenotype in peripheral blood and DNTT was the cytotoxic phenotype (CD56+ CD16+), while the presence of these cells was significantly decreased in ATT and further decreased in TT. Finally, the immunologic response differed between adenocarcinoma and squamous cell carcinoma and according to the tumor differentiation grade. These findings on the infiltration of innate and adaptative immune cells into tumors contribute to a more complete picture of the immune reaction in NSCLC. PMID- 27689403 TI - Blockade of the Hedgehog pathway downregulates estrogen receptor alpha signaling in breast cancer cells. AB - Anti-estrogen treatment, exemplified by tamoxifen, is a well-established adjuvant therapy for estrogen receptor alpha (ERalpha)-positive breast cancer. However, the effectiveness of this drug is limited due to the development of resistance. The Hedgehog (HH) signaling pathway is critical in embryonic development, and aberrant activation of this transduction cascade is linked to various malignancies. However, it remains unclear whether HH signaling is activated in human breast cancer and related to tamoxifen resistance. Deciphering how this pathway may be involved in breast cancer is a crucial step towards the establishment of targeted combinatorial treatments for this disease. Here, we show that the expression of the HH signaling effector protein GLI1 is higher in tamoxifen resistant compared to sensitive cells. Tamoxifen resistant cells have stronger ERalpha transcriptional activity relative to sensitive cells, even though the ERalpha expression is similar in both cell types. Knockdown of GLI1 attenuates cell proliferation and reduces ERalpha transcriptional activity in both sensitive and resistant cells, irrespective of estrogen stimulation. Combinatorial treatment of tamoxifen and the GLI antagonist GANT61 further suppresses the growth of sensitive and resistant cells relative to administration of only tamoxifen, and this was irrespective of estrogen stimulation. Moreover, a positive correlation between GLI1 and ERalpha expression was identified in breast cancer samples. Additionally, high GLI1 expression predicted worse distant metastasis-free survival in breast cancer patients. These data suggest that the HH pathway may be a new candidate for therapeutic targeting and prognosis in ERalpha-positive breast cancer. PMID- 27689406 TI - Measuring the Pharmacokinetic Properties of Drugs with a Novel Surgical Rat Model. AB - : Purpose/aim of the study: The pharmacokinetic (PK) parameters in animal models can help optimize novel candidate drugs prior to human trials. However, due to the complexity of pharmacokinetic experiments, their use is limited in academia. We present a novel surgical rat model for investigation of pharmacokinetic parameters and its use in an anti-obesity drug development program. MATERIALS AND METHODS: The model uses anesthetized male Wistar rats, a jugular, a femoral catheter, and an insulin pump for peptide infusion. The following pharmacokinetic parameters were measured: metabolic clearance rate (MCR), half-life, and volume of distribution (Vd). Glucagon-like peptide 1 (GLP-1), glucagon (GCG), and exendin-4 (Ex-4) were used to validate the model. The pharmacokinetic parameters of anti-obesity drug candidates X1, X2, and X3 were measured. RESULTS: GLP-1 had a significantly higher MCR (83.9 +/- 14.1 mL/min/kg) compared to GCG (40.7 +/- 14.3 mL/min/kg) and Ex-4 (10.1 +/- 2.5 mL/min/kg) (p < .01 and p < .001 respectively). Ex-4 had a statistically significant longer half-life (35.1 +/- 7.4 min) compared to both GCG (3.2 +/- 1.7 min) and GLP-1 (1.2 +/- 0.4 min) (p < .01 for both GCG and GLP-1). Ex-4 had a statistically significant higher volume of distribution (429.7 +/- 164.9 mL/kg) compared to both GCG (146.8 +/- 49.6 mL/kg) and GLP-1 (149.7 +/- 53.5 mL/kg) (p < .01 for both GCG and GLP-1). Peptide X3 had a statistically significant longer half-life (21.3 +/- 3.5 min) compared to both X1 (3.9 +/- 0.4 min) and X2 (16.1 +/- 2.8 min) (p < .001 for both X1 and X2). CONCLUSIONS: We present an affordable and easily accessible platform for the measurement of PK parameters of peptides. This novel surgical rat model produces consistent and reproducible results while minimizing animal use. PMID- 27689407 TI - Contraceptive counselling of women seeking abortion - a qualitative interview study of health professionals' experiences. AB - OBJECTIVES: A substantial proportion of women who undergo an abortion continue afterwards without switching to more effective contraceptive use. Many subsequently have repeat unintended pregnancies. This study, therefore, aimed to identify and describe health professionals experiences of providing contraceptive counselling to women seeking an abortion. METHODS: We interviewed 21 health professionals (HPs), involved in contraceptive counselling of women seeking abortion at three differently sized hospitals in Sweden. The interviews were recorded and transcribed verbatim and analysed using conventional qualitative content analysis. RESULTS: Three clusters were identified: 'Complex counselling', 'Elements of counselling' and 'Finding a method'. HPs often experienced consultations including contraceptive counselling at the time of an abortion as complex, covering both pregnancy termination and contraceptive counselling. Women with vulnerabilities placed even greater demands on the HPs providing counselling. The HPs varied in their approaches when providing contraceptive counselling but also in their knowledge about certain contraception methods. HPs described challenges in finding out if women had found an effective method and in the practicalities of arranging intrauterine device (IUD) insertion post abortion, when a woman asked for this method. CONCLUSIONS: HPs found it challenging to provide contraceptive counselling at the time of an abortion and to arrange access to IUDs post-abortion. There is a need to improve their counselling, their skills and their knowledge to prevent repeat unintended pregnancies. PMID- 27689408 TI - Development of loteprednol etabonate-loaded cationic nanoemulsified in-situ ophthalmic gel for sustained delivery and enhanced ocular bioavailability. AB - A novel cationic nanoemulsified in-situ ophthalmic gel of loteprednol etabonate (LE) was developed to improve the permeability and retention time of formulations for overall improvement of drug's ocular bioavability. Capryol 90 (oil phase), tween 80 (surfactant) and transcutol P (cosurfactant) was selected as formulation excipients to construct pseudoternary phase diagrams and nanoemulsion region was recognized from diagrams. Spontaneous emulsification method was used to manufacture LE nanoemulsion and it was optimized using 32 factorial design by considering the amount of oil and the ratio of surfactant to cosurfactant (Smix) as independent variables and evaluated for various physicochemical properties. Optimized NE was dispersed in Poloxamer 407 and 188 solution to form nanoemulsified sols that were predictable to transform into in-situ gels at corneal temperature. Drug pharmacokinetics of sterilized optimized in situ NE gel, NE-ISG2 [0.69% w/w Capryol 90, 0.99%w/w Smix (3:1), 13% Poloxamer 407, 4% w/w Poloxamer 188] and marketed formulation were assessed in rabbit aqueous humor. The in-situ gels were clear, shear thinning in nature and displayed zero order drug release kinetics. NE-ISG2 showed the minimum ocular irritation potential and significantly (p < 0.01) higher Cmax and AUC(0-10 h), delayed Tmax, extended mean residence time and improved (2.54-fold times) bioavailability compared to marketed formulation. PMID- 27689409 TI - Increased Metabolic Disorders and Impaired Insulin Secretory Function in the First-Degree Relatives of Type 2 Diabetic Patients with Normal Glucose Tolerance. AB - OBJECTIVE: To compare the metabolic status and pancreatic beta-cell function in first-degree relatives (FDRs) of type 2 diabetic patients with normal glucose tolerance (NGT). MATERIALS AND METHODS: Three hundred twelve subjects, who were NGT-FDR of type 2 diabetic patients and 1348 subjects, who were NGT individuals with no family history of diabetes, were defined as NGT-FDRs and NGT-controls (NGT-C), respectively. Blood pressure, body weight, waist circumference, plasma glucose, lipid profile, and insulin levels were measured in all subjects. Homeostasis model assessment of insulin resistance (HOMA-IR), HOMA-beta, insulin sensitivity index (ISI), and disposition index (DI) was used to evaluate insulin resistance and insulin sensitivity. RESULTS: The HOMA-IR and HOMA-beta indices were significantly higher in the NGT-FDR group relative to the NGT-C, while the ISI, DI, and DeltaI30/DeltaG30 were lower (P < 0.05). The prevalence rate of greater than or equal to three metabolic disorders was higher in the NGT-FDR group compared to the NGT-C (P < 0.05). In the NGT-FDR group, compared to people with normal metabolism, HOMA-beta decreased when there was only one metabolic disorder, increased slightly when there were two to three metabolic abnormalities, and decreased again when there were four or more metabolic abnormalities. The data also indicated that having a family history of type 2 diabetes maybe an independent risk factor of beta-cell dysfunction. CONCLUSIONS: Metabolic disorders developed frequently in the NGT-FDRs of type 2 diabetic patients. As the number of coexisting metabolic disorders increased, pancreatic beta-cell secretory ability and insulin sensitivity decreased. Therefore, it is necessary to provide early preventive interventions and monitoring of metabolic indices for NGT-FDRs of type 2 diabetic patients. PMID- 27689410 TI - The Effects of Costaria costata Extracts on Atopic Dermatitis in an In Vitro Model. AB - We have provided a protocol for establishing an atopic dermatitis (AD) in vitro model, and evaluated the effects of Costaria costata (CC) extracts on AD in an in vitro model using keratinocytes and splenocytes from AD-induced mice and mast cells. HaCaT cells were each treated with 200 MUg/mL of CC water extract (CCW), CC 10% ethanol extract (CCE10%), and CC 70% ethanol extract (CCE70%), immediately followed by stimulation with 20 ng/mL tumor necrosis factor (TNF)-alpha, and 20 ng/mL interferon (IFN)-gamma for inflammation. The splenocytes from AD-induced mice were each treated with 200 MUg/mL of CCW, CCE10%, and CCE70%, followed by stimulation with 5 MUg/mL ConA or lipopolysaccharide (LPS), to induce T cell or B cell activation, and 5 MUg/mL LPS and 50 ng/mL interleukin-4, to induce immunoglobulin (Ig) E production. We investigated the effects of CCW, CCE10%, and CCE70% on the production of histamine in PMA, and A23187-stimulated MC/9 cells. We found that treatments with CC extracts decreased the production of proinflammatory cytokines in TNF-alpha and IFN-gamma-stimulated HaCaT cells, and the suppression of the imbalance of Th1/Th2 cytokines and IgE production on primary splenocytes. In addition, CC extracts resulted in a decrease in histamine release in the PMA and A23187-simulated MC/9 cells. According to our present results, we can conclude that CC extracts may be effective for the treatment of other allergy diseases, and AD, via the attenuation of allergic reactions. PMID- 27689412 TI - Development and optimization of transferrin-conjugated nanostructured lipid carriers for brain delivery of paclitaxel using Box-Behnken design. AB - The treatment of brain cancer remains one of the most difficult challenges in oncology. The purpose of this study was to develop transferrin-conjugated nanostructured lipid carriers (Tf-NLCs) for brain delivery of paclitaxel (PTX). PTX-loaded NLCs (PTX-NLCs) were prepared using solvent evaporation method and the impact of various formulation variables were assessed using Box-Behnken design. Optimized PTX-NLC was coupled with transferrin as targeting ligand and in vitro cytotoxicity of it was investigated against U-87 brain cancer cell line. As a result, 14.1 mg of cholesterol, 18.5 mg of triolein, and 0.5% poloxamer were used to prepare the optimal formulation. Mean particle size (PS), zeta potential (ZP), entrapment efficiency (EE), drug loading (DL), mean release time (MRT) of adopted formulation were confirmed to be 205.4 +/- 11 nm, 25.7 +/- 6.22 mV, 91.8 +/- 0.5%, 5.38 +/- 0.03% and 29.3 h, respectively. Following conjugation of optimized PTX-NLCs with transferrin, coupling efficiency was 21.3 mg transferrin per mmol of stearylamine; PS and MRT were increased while ZP, EE and DL decreased non significantly. Tf-PTX-NLCs showed higher cytotoxic activity compared to non targeted NLCs and free drug. These results indicated that the Tf-PTX-NLCs could potentially be exploited as a delivery system in brain cancer cells. PMID- 27689413 TI - Estrogens Exacerbate Nociceptive Pain via Up-Regulation of TRPV1 and ANO1 in Trigeminal Primary Neurons of Female Rats. AB - Several trigeminal pain disorders show sex differences, and high levels of estrogens may underlie these differences. The interaction between transient receptor potential vanilloid 1 (TRPV1) and anoctamin 1 (ANO1) plays an important role in peripheral nociception. However, whether TRPV1 and ANO1 are involved in estrogen-modulated trigeminal pain sensitivity is unclear. In this study, we examined estradiol (E2) modulation of nociception through behavioral and immunohistological experiments after application of capsaicin (Cap), a selective TRPV1 agonist, onto the ocular surface in ovariectomized rats treated with high dose E2 (HE) or low-dose E2 (LE) for 2 days. In addition, we used real-time PCR to study the effects of E2 on the expression levels of TRPV1 and ANO1 mRNA in trigeminal ganglia. In the behavioral experiment, the HE group showed significant potentiation of Cap-evoked nocifensive behavior compared with the LE group. Immunohistochemistry showed that Cap evoked a significantly greater number of cells that were immunoreactive for c-Fos, a marker of nociceptive activation, in the trigeminal subnucleus caudalis/upper cervical cord in the HE group than in the LE group. The number of c-Fos-immunoreactive cells in the ventral trigeminal interpolaris/caudalis were similar in the 2 groups. Real-time PCR showed that the levels of TRPV1 and ANO1 mRNA in the HE group were significantly higher than levels in the LE group. Thus, high levels of estrogens may be a risk factor for Cap-evoked nociceptive pain, and estrogen-dependent increases in TRPV1 and ANO1 are likely involved in modulating the nociceptive response in the trigeminal area. PMID- 27689414 TI - Igf Binding Proteins Protect Undifferentiated Spermatogonia in the Zebrafish Testis Against Excessive Differentiation. AB - IGF binding proteins (IGFBPs) modulate the availability of IGFs for their cognate receptors. In zebrafish testes, IGF3 promotes the proliferation and differentiation of type A undifferentiated (Aund) spermatogonia, and igf3 expression is strongly elevated by FSH but also responds to T3. Here we report the effects of FSH and T3 on igfbp transcript levels in adult zebrafish testis. We then examined T3 and FSH effects on zebrafish spermatogenesis and explored the relevance of IGFBPs in modulating these T3 or FSH effects, using a primary tissue culture system for adult zebrafish testis. T3 up-regulated igfbp1a and igfbp3 expression, whereas FSH reduced igfbp1a transcript levels. To quantify effects on spermatogenesis, we determined the mitotic index and relative section areas occupied by Aund, type A differentiating, or type B spermatogonia. In general, T3 and FSH stimulated spermatogonial proliferation and increased the areas occupied by spermatogonia, suggesting that both self-renewal and differentiating divisions were stimulated. Preventing IGF/IGFBP interaction by NBI-31772 further increased T3- or FSH-induced spermatogonial proliferation. However, under these conditions the more differentiated type A differentiating and B spermatogonia occupied larger surface areas at the expense of the area held by Aund spermatogonia. Clearly decreased nanos2 transcript levels are in agreement with this finding, and reduced amh expression may have facilitated spermatogonial differentiation. We conclude that elevating IGF3 bioactivity by blocking IGFBPs shifted T3- or FSH induced signaling from stimulating spermatogonial self-renewal as well as differentiation toward predominantly stimulating spermatogonial differentiation, which leads to a depletion of type Aund spermatogonia. PMID- 27689411 TI - Mechanisms and functions of extracellular vesicle release in vivo-What we can learn from flies and worms. AB - Cells from bacteria to man release extracellular vesicles (EVs) that contain signaling molecules like proteins, lipids, and nucleic acids. The content, formation, and signaling roles of these conserved vesicles are diverse, but the physiological relevance of EV signaling in vivo is still debated. Studies in classical genetic model organisms like C. elegans and Drosophila have begun to reveal the developmental and behavioral roles for EVs. In this review, we discuss the emerging evidence for the in vivo signaling roles of EVs. Significant effort has also been made to understand the mechanisms behind the formation and release of EVs, specifically of exosomes derived from exocytosis of multivesicular bodies and of microvesicles derived from plasma membrane budding called ectocytosis. In this review, we detail the impact of flies and worms on understanding the proteins and lipids involved in EV biogenesis and highlight the open questions in the field. PMID- 27689415 TI - Glucose Transporter-4 Facilitates Insulin-Stimulated Glucose Uptake in Osteoblasts. AB - Recent studies have identified the osteoblast as an insulin responsive cell that participates in global energy homeostasis. Here, we show that glucose transporter 4 (Glut4) is required for insulin-dependent uptake and oxidation of glucose in mature osteoblasts. In primary cultures of mouse osteoblasts, insulin increased uptake and oxidation of 14C-glucose in a dose-dependent fashion but did not significantly affect uptake or oxidation of 14C-oleate. In vitro, undifferentiated osteoblasts expressed 3 high-affinity Gluts: Glut1, Glut4, and Glut3. However, although levels of Glut1 and Glut3 remained constant during the course of osteoblast differentiation, Glut4 expression increased by 5-fold in association with enhanced insulin-stimulated glucose uptake. Glut4 ablation in osteoblasts in vitro eliminated insulin-stimulated glucose uptake, reduced proliferation and diminished measures of osteoblast maturation. In vivo, Glut4 expression was observed in osteoblasts, osteocytes, and chondrocytes at a level approaching that observed in adjacent skeletal muscle. To determine the importance of Glut4 in bone in vivo, we generated mice lacking Glut4 in osteoblasts and osteocytes (DeltaGlut4). DeltaGlut4 mice exhibited normal bone architecture but exhibited an increase in peripheral fat in association with hyperinsulinemia, beta-cell islet hypertrophy, and reduced insulin sensitivity. Surprisingly, the expression of insulin target genes in liver, muscle, and adipose from DeltaGlut4 mice were unchanged or increased, indicating that alterations in glucose homeostasis were the result of reduced clearance by bone. These findings suggest that Glut4 mediates insulin-stimulated glucose uptake by mature osteoblasts/osteocytes and that the magnitude of glucose use by bone cells is sufficient to impact global glucose disposal in the mouse. PMID- 27689416 TI - Attitudes in Patients with Autosomal Dominant Polycystic Kidney Disease Toward Prenatal Diagnosis and Preimplantation Genetic Diagnosis. AB - AIMS: No recommendations currently exist regarding implementation of both prenatal diagnosis and preimplantation genetic diagnosis (PGD) for autosomal dominant polycystic kidney disease (ADPKD). This study evaluated attitudes in ADPKD patients with either chronic kidney disease (CKD) stages I-IV or end-stage renal failure (ESRF) toward prenatal diagnosis and PGD. METHODS: Ninety-six ADPKD patients were recruited from an outpatient clinic, wards, and dialysis units. Thirty-eight patients had ESRF and 58 had CKD stages I-IV. Participants were given an information sheet on prenatal diagnosis and PGD and subsequently completed a questionnaire. RESULTS: The median age of participants was 51.5 years. Seventeen percent of ADPKD patients with CKD and 18% of ADPKD patients with ESRF would consider prenatal diagnosis and termination of pregnancy for ADPKD. Fifty percent with CKD would have opted for PGD (or might consider it in the future) were it available and funded by the UK National Health Service, compared to 63% in the ESRF group (p = 0.33). Sixty-nine percent in the CKD group and 68% in the ESRF group believed that PGD should be offered to other patients. DISCUSSION: There was a spectrum of attitudes among this cohort. A proportion of patients believe that PGD should be made available to prospective parents with this disease. The discrepancy between the low proportion (17% CKD, 18% ESRF) who would consider prenatal diagnosis and termination of pregnancy and the higher number who hypothetically express an intention or wish to access PGD (50% CKD and 63% ESRF) indicates far greater acceptability for diagnostic methods that occur before embryo implantation. It is not known how the development of methods to identify patients whose renal function is likely to decline rapidly and treatments altering the natural history of ADPKD will affect these attitudes. PMID- 27689417 TI - Immunovirological Efficacy of Once-Daily Maraviroc Plus Ritonavir-Boosted Atazanavir After 48 Weeks in Naive HIV-Infected Patients. AB - Toxicities related to the use of nucleoside analogues have increased the interest in developing nucleoside-sparing regimens, mainly combining protease inhibitors with raltegravir. However, data regarding the use of CCR5-antagonists in this setting and in the naive scenario are scarce. The main objective was to analyze the immunovirological efficacy and tolerability of a low-dose, once-daily, maraviroc (MVC)-containing, nucleoside reverse transcriptase inhibitor-sparing dual therapy compared with standard triple therapy after 48 weeks for naive HIV infected patients in the routine clinical practice setting. All naive HIV infected patients with stable clinical condition that started antiretroviral treatment since February 1, 2008 to May 30,h 2012 were included. MVC clinical test was used to select candidate subjects to MVC therapy. Thirty-two subjects with MVC + atazanavir/ritonavir (ATV/r) and 66 with standard triple therapy were analyzed. A comparable virological efficacy between groups was found after 48 weeks (87.5% vs. 80.3% of HIV undetectability, p = 0.37, MVC + ATV/r and triple therapy groups, respectively). The CD4 recovery after 48 weeks was similar and more than 200 cells/mm3 in both groups. No need of therapy changes or treatment discontinuations was observed in the MVC + ATV/r group. Effect on lipid profile, high-sensitivity C reactive protein, and beta2-microglobulin was similar for both groups. Noteworthy, a significant increase of erythrocyte mean corpuscular volume was observed only in the triple therapy group. A nucleoside-sparing MVC containing dual therapy showed similar immunovirological efficacy and tolerability than standard triple therapy in naive HIV-infected patients. PMID- 27689418 TI - Differences in the chemical composition of Enterococcus faecalis biofilm under conditions of starvation and alkalinity. AB - ABSTACT This study aimed to investigate the dynamic changes that occur in the chemical composition of an Enterococcus faecalis (E. faecalis) biofilm under conditions of starvation and in an alkaline environment and to explore the function of chemical composition changes in the resistance of the E. faecalis biofilm to an extreme environment. This study established an in vitro E. faecalis biofilm model under starvation and in an alkaline environment. During the formation of the biofilm, the pH value and nutritional condition of the culture medium were changed, and the changes in chemical composition were observed using biochemical measures. The results showed that, when the pH value of the culture medium was 11, the percentage of water-insoluble polysaccharides in the biofilm was significantly lower than under other conditions. In addition, the percentage of water-soluble polysaccharides in culture medium with pH values of 9 and 11 gradually decreased. The level of the water-soluble polysaccharides in each milligram of dry weight of biofilm at pH 11 increased compared to that under other conditions. The results from this study indicate that the chemical composition of E. faecalis biofilm changed in extreme environments. These changes served as a defensive mechanism for E. faecalis against environmental pressures. PMID- 27689419 TI - Control of disinfection by-products in canned vegetables caused by water used in their processing. AB - Canned vegetables come into contact with sanitizers and/or treated water in industry during several steps (namely washing, sanitising, blanching and filling with sauces or brine solutions) and therefore they can contain disinfection by products - DBPs). This study focused on the occurrence of trihalomethanes (THMs) and haloacetic acids (HAAs) in a wide variety of canned vegetables (75 samples). For each vegetable, the edible solid and liquid phases of the package were separated and analysed individually. DBPs can be present in both solid (up to eight species) and liquid (up to 11 species) phases, their levels being higher in liquid ones. Volatile THMs predominate in the edible solid phase (up to four species), while HAAs do so in the liquid phase (up to five species) according to their ionic and non-volatile nature. The lowest concentrations of DBPs were found in tomatoes because they were often preserved in their own juice, without water. PMID- 27689420 TI - A novel minimally invasive, dorsolateral, tubular partial odontoidectomy and autologous bone augmentation to treat dens pseudarthrosis: cadaveric, 3D virtual simulation study and technical report. AB - OBJECTIVE The goal of this study was to demonstrate the clinical and technical nuances of a minimally invasive, dorsolateral, tubular approach for partial odontoidectomy, autologous bone augmentation, and temporary C1-2 fixation to treat dens pseudarthrosis. METHODS A cadaveric feasibility study, a 3D virtual reality reconstruction study, and the subsequent application of this approach in 2 clinical cases are reported. Eight procedures were completed in 4 human cadavers. A minimally invasive, dorsolateral, tubular approach for odontoidectomy was performed with the aid of a tubular retraction system, using a posterolateral incision and an oblique approach angle. Fluoroscopy and postprocedural CT, using 3D volumetric averaging software, were used to evaluate the degree of bone removal of C1-2 lateral masses and the C-2 pars interarticularis. Two clinical cases were treated using the approach: a 23-year-old patient with an odontoid fracture and pseudarthrosis, and a 35-year-old patient with a history of failed conservative treatment for odontoid fracture. RESULTS At 8 cadaveric levels, the mean volumetric bone removal of the C1-2 lateral masses on 1 side was 3% +/- 1%, and the mean resection of the pars interarticularis on 1 side was 2% +/- 1%. The median angulation of the trajectory was 50 degrees , and the median distance from the midline of the incision entry point on the skin surface was 67 mm. The authors measured the diameter of the working channel in relation to head positioning and assessed a greater working corridor of 12 +/- 4 mm in 20 degrees inclination, 15 degrees contralateral rotation, and 5 degrees lateral flexion to the contralateral side. There were no violations of the dura. The reliability of C-2 pedicle screws and C-1 lateral mass screws was 94% (15 of 16 screws) with a single lateral breach. The patients treated experienced excellent clinical outcomes. CONCLUSIONS A minimally invasive, dorsolateral, tubular odontoidectomy and autologous bone augmentation combined with C1-2 instrumentation has the ability to provide excellent 1-stage management of an odontoid pseudarthrosis. The procedure can be completed safely and successfully with minimal blood loss and little associated morbidity. This approach has the potential to provide not only a less invasive approach but also a function-preserving option to treat complex C1-2 anterior disease. PMID- 27689421 TI - Diffusion tensor imaging as a biomarker for assessing neuronal stem cell treatments affecting areas distal to the site of spinal cord injury. AB - OBJECTIVE The aims of this study were to determine if the morphological and functional changes induced by neural stem cell (NSC) grafts after transplantation into the rodent spinal cord can be detected using MR diffusion tensor imaging (DTI) and, furthermore, if the DTI-derived mean diffusivity (MD) metric could be a biomarker for cell transplantation in spinal cord injury (SCI). METHODS A spinal contusion was produced at the T-8 vertebral level in 40 Sprague Dawley rats that were separated into 4 groups, including a sham group (injury without NSC injection), NSC control group (injury with saline injection), co-injection control group (injury with Prograf), and the experimental group (injury with NSC and Prograf injection). The NSC injection was completed 1 week after injury into the site of injury and the rats in the experimental group were compared to the rats from the sham, NSC control, and co-injection groups. The DTI index, MD, was assessed in vivo at 2, 5, and 10 weeks and ex vivo at 10 weeks postinjury on a 9.4-T Bruker scanner using a spin-echo imaging sequence. DTI data of the cervical spinal cord from the sham surgery, injury with saline injection, injury with injection of Prograf only, and injury with C17.2 NSC and Prograf injection were examined to evaluate if cellular proliferation induced by intrathoracic C17.2 engraftment was detectable in a noninvasive manner. RESULTS At 5 weeks after injury, the average fractional anisotropy, longitudinal diffusion (LD) and radial diffusion (RD) coefficients, and MD of water (average of the RD and LD eigenvalues in the stem cell line-treated group) increased to an average of 1.44 * 10-3 sec/mm2 in the cervical segments, while the control groups averaged 0.98 * 10-3 s/mm2. Post hoc Tukey's honest significant difference tests demonstrated that the transplanted stem cells had significantly higher MD values than the other groups (p = 0.032 at 5 weeks). In vivo and ex vivo findings at 10 weeks displayed similar results. This statistical difference between the stem cell line and the other groups was maintained at the 10-week postinjury in vivo and ex vivo time points. CONCLUSIONS These results indicate that the DTI-derived MD metric collected from noninvasive imaging techniques may provide useful biomarker indices for transplantation interventions that produce changes in the spinal cord structure and function. Though promising, the results demonstrated here suggest additional work is needed before implementation in a clinical setting. PMID- 27689422 TI - Intraoperative electrophysiological monitoring for C1-2 spinal cord stimulation. AB - OBJECTIVE This study is a retrospective case series involving C1-2 spinal cord stimulation in patients with complex regional pain syndrome (CRPS) under general endotracheal anesthesia. Currently, C1-2 paddle lead placement is an accepted practice, which provides effective cervical stimulation to ameliorate upper extremity and sometimes lower-extremity symptoms experienced by patients with CRPS. However, this technique must be performed under general endotracheal anesthesia rather than in an awake or semiconscious state due to intraoperative safety concerns and patient comfort. The authors aim to provide additional data to support the following novel technique: the use of somatosensory evoked potential (SSEP) diminution data to assist with proper midline placement of C1-2 leads under general anesthesia. METHODS SSEP median nerve (MN) and posterior tibial nerve (PTN) data were collected from 6 patients undergoing placement of C1 2 leads under general anesthesia. Fluoroscopy was used as an initial guide for proper anatomical midline placement. This was followed by the activation of the spinal cord stimulator and simultaneous collection of primarily MN SSEPs as well as PTN SSEPs for physiological midline placement. Unilateral and bilateral reductions in SSEPs assisted with the correct lateralization of the lead to ensure effective postoperative coverage according to the patient's individual preoperative symptoms. RESULTS Six patients were monitored using SSEPs and repeatable, reliable MN and PTN baseline responses were obtained from all. A reduction in amplitude ranging from 5% to 87% was observed, confirming inhibition of dorsal column conduction, and an average pain relief of 63% at short-term and 64% at long-term follow-up was recorded with 6 of 6 and 5 of 6 patients responding, respectively. CONCLUSIONS Intraoperative SSEP collision study testing appears to be a safe technique to monitor placement of C1-2 paddle leads intraoperatively under general anesthesia.

PMID- 27689424 TI - Preoperative mental health status may not be predictive of improvements in patient-reported outcomes following an anterior cervical discectomy and fusion. AB - OBJECTIVE Prior studies have correlated preoperative depression and poor mental health status with inferior patient-reported outcomes following lumbar spinal procedures. However, literature regarding the effect of mental health on outcomes following cervical spinal surgery is limited. As such, the purpose of this study is to test for the association of preoperative SF-12 Mental Component Summary (MCS) scores with improvements in Neck Disability Index (NDI), SF-12 Physical Component Summary (PCS), and neck and arm pain following anterior cervical discectomy and fusion (ACDF). METHODS A prospectively maintained surgical database of patients who underwent a primary 1- or 2-level ACDF during 2014-2015 was reviewed. Patients were excluded if they did not have complete patient reported outcome data for the preoperative or 6-week, 12-week, or 6-month postoperative visits. At baseline, preoperative SF-12 MCS score was assessed for association with preoperative NDI, neck visual analog scale (VAS) score, arm VAS score, and SF-12 PCS score. The preoperative MCS score was then tested for association with changes in NDI, neck VAS, arm VAS, and SF-12 PCS scores from the preoperative visit to postoperative visits. These tests were conducted using multivariate regression controlling for baseline characteristics as well as for the preoperative score for the patient-reported outcome being assessed. RESULTS A total of 52 patients were included in the analysis. At baseline, a higher preoperative MCS score was negatively associated with a lower preoperative NDI (coefficient: -0.74, p < 0.001) and preoperative arm VAS score (-0.06, p = 0.026), but not preoperative neck VAS score (-0.03, p = 0.325) or SF-12 PCS score (0.04, p = 0.664). Additionally, there was no association between preoperative MCS score and improvement in NDI, neck VAS, arm VAS, or SF-12 PCS score at any of the postoperative time points (6 weeks, 12 weeks, and 6 months, p > 0.05 for each). The percentage of patients achieving a minimum clinically important difference at 6 months did not differ between the bottom and top MCS score halves (p > 0.05 for each). CONCLUSIONS The results of this study suggest that better preoperative mental health status is associated with lower perceived preoperative disability but is not associated with severity of preoperative neck or arm pain. In contrast to other studies, the present study was unable to demonstrate that preoperative mental health is predictive of improvement in patient-reported outcomes at any postoperative time point following an ACDF. PMID- 27689425 TI - Prediction based on preoperative opioid use of clinical outcomes after transforaminal lumbar interbody fusions. AB - OBJECTIVE Opioid analgesics have become some of the most prescribed drugs in the world, despite the lack of long-term studies evaluating the benefits of opioid medications versus their risks associated with chronic use. In addition, long term opioid use may be associated with worse long-term clinical outcomes. The primary objective of this study was to evaluate whether preoperative opioid use predicted inferior clinical outcomes among patients undergoing transforaminal lumbar interbody fusion (TLIF) for symptomatic lumbar degenerative disc disease. METHODS The authors of this observational study prospectively enrolled 93 patients who underwent 1-level to 2-level TLIFs in 2011-2014; the patient cohort was divided into 2 groups according to preoperative opioid use or no such use. Visual analog scale (VAS) scores for low-back pain and leg pain, Oswestry Disability Index scores, and the scores of the mental component summary (MCS) and physical component summary (PCS) on the 36-Item Short Form Health Survey were used to assess pain, disability, and health-related quality of life outcomes, respectively. The clinical scores for the 2 groups were determined preoperatively and at a 12-month follow-up examination. RESULTS In total, 60 (64.5%) patients took prescribed opioid medications preoperatively. Compared with those not taking opioids preoperatively, these patients had significantly higher VAS scores for low-back pain (p = 0.016), greater disability (p = 0.013), and lower PCS scores (p = 0.03) at the 12-month follow-up. The postoperative MCS scores were also significantly lower (p = 0.035) in the opioid-use group, but these lower scores were due to significantly lower baseline MCS scores in this group. A linear regression analysis did not detect opioid dose-related effects on leg and back pain, disability, and MCS and PCS scores, suggesting that poorer outcomes are not significantly correlated with higher opioid doses taken by the patients. CONCLUSIONS The use of opioid medications to control pain before patients underwent lumbar fusion for degenerative lumbar conditions was associated with less favorable clinical outcomes postoperatively. This is the first study that has demonstrated this association in a homogeneous cohort of patients undergoing TLIF; this association should be studied further to evaluate the conclusions of the present study.

PMID- 27689428 TI - Safety of intensivist-led bedside decannulation of internal jugular bi-caval dual lumen veno-venous extracorporeal membrane oxygenation cannulas and report of technique. AB - BACKGROUND: In the past decade, the rate and utilization of veno-venous extracorporeal membrane oxygenation (VV-ECMO) has increased dramatically. A single catheter technique has recently come into favour for providing VV-ECMO. Although it has been shown that intensivists can safely place these catheters, the safety of decannulation by intensivists has not been reported in the literature. OBJECTIVE: We describe a technique for safely decannulating the Avalon Elite VV-ECMO catheter at the bedside and assess the safety of this technique, as compared with the standard technique of decannulation in the operating room by a surgeon. METHODS: This was a retrospective cohort design conducted at a tertiary care cardiovascular intensive care unit at an academic medical centre. All patients who underwent VV-ECMO from 2009 to 2014 were included in the study except for those who had been decannulated for withdrawal of care. Complication rates from decannulation were compared between patients who were decannulated by surgeons in the operating room and those decannulated by intensivists in the intensive care unit (ICU). RESULTS: Twenty-eight patients were included in this study, of whom twenty-three patients (82%) were decannulated by intensivists, board certified in Critical Care Medicine through the American Board of Anesthesiology, while five (18%) the patients were decannulated by a surgeon. There was no significant difference in the complications rates between the surgeons (0) and intensivists (1) (P = 1.00). There were no major complications requiring operative intervention associated with decannulation identified in this study. CONCLUSIONS: It is safe for intensivists to decannulate the Avalon Elite VV-ECMO cannula in the ICU using our purse-string suture technique. Performing these decannulations at the bedside compared to operating room may have positive clinical ramifications that include improved patient safety, timely patient care and reduced operating room costs. PMID- 27689427 TI - Development and Validation of the EXPECT Questionnaire: Assessing Patient Expectations of Outcomes of Complementary and Alternative Medicine Treatments for Chronic Pain. AB - BACKGROUND: Patient expectations may be associated with outcomes of complementary and alternative medicine (CAM) treatments for chronic pain. However, a psychometrically sound measure of such expectations is needed. OBJECTIVES: The purpose of this study was to develop and evaluate a questionnaire to assess individuals' expectations regarding outcomes of CAM treatments for chronic low back pain (CLBP), as well as a short form of the questionnaire. METHODS: An 18 item draft questionnaire was developed through literature review, cognitive interviews with individuals with CLBP, CAM practitioners, and expert consultation. Two samples completed the questionnaire: (1) a community sample (n = 141) completed it via an online survey before or soon after starting a CAM treatment for CLBP, and (2) participants (n = 181) in randomized clinical trials evaluating CAM treatments for CLBP or fibromyalgia completed it prior to or shortly after starting treatment. Factor structure, internal consistency, test retest reliability, and criterion validity were examined. RESULTS: Based on factor analyses, 10 items reflecting expectations (used to create a total score) and three items reflecting hopes (not scored) were selected for the questionnaire. The questionnaire had high internal consistency, moderate test retest reliability, and moderate correlations with other measures of expectations. A three-item short form also had adequate reliability and validity. CONCLUSIONS: The Expectations for Complementary and Alternative Medicine Treatments (EXPECT) questionnaire can be used in research to assess individuals' expectations of treatments for chronic pain. It is recommended that the three hope questions are included (but not scored) to help respondents distinguish between hopes and expectations. The short form may be appropriate for clinical settings and when expectation measurement is not a primary focus. PMID- 27689426 TI - Hysteresis in voltage-gated channels. AB - Ion channels constitute a superfamily of membrane proteins found in all living creatures. Their activity allows fast translocation of ions across the plasma membrane down the ion's transmembrane electrochemical gradient, resulting in a difference in electrical potential across the plasma membrane, known as the membrane potential. A group within this superfamily, namely voltage-gated channels, displays activity that is sensitive to the membrane potential. The activity of voltage-gated channels is controlled by the membrane potential, while the membrane potential is changed by these channels' activity. This interplay produces variations in the membrane potential that have evolved into electrical signals in many organisms. These signals are essential for numerous biological processes, including neuronal activity, insulin release, muscle contraction, fertilization and many others. In recent years, the activity of the voltage-gated channels has been observed not to follow a simple relationship with the membrane potential. Instead, it has been shown that the activity of voltage-gated channel displays hysteresis. In fact, a growing number of evidence have demonstrated that the voltage dependence of channel activity is dynamically modulated by activity itself. In spite of the great impact that this property can have on electrical signaling, hysteresis in voltage-gated channels is often overlooked. Addressing this issue, this review provides examples of voltage-gated ion channels displaying hysteretic behavior. Further, this review will discuss how Dynamic Voltage Dependence in voltage-gated channels can have a physiological role in electrical signaling. Furthermore, this review will elaborate on the current thoughts on the mechanism underlying hysteresis in voltage-gated channels. PMID- 27689429 TI - Changes in heart rate variability during anaesthesia induction using sevoflurane or isoflurane with nitrous oxide. AB - BACKGROUND: The purpose of this study was to compare cardiac sympathetic and parasympathetic balance using heart rate variability (HRV) during induction of anaesthesia between sevoflurane and isoflurane in combination with nitrous oxide. METHODS: 40 individuals aged from 30 to 60 years, scheduled for general anaesthesia were equally divided into sevoflurane or isoflurane groups. After 100% oxygen inhalation for a few minutes, anaesthesia was induced with nitrous oxide 3 L min-1, oxygen 3 L min-1 and sevoflurane or isoflurane. Sevoflurane or isoflurane concentration was increased by 0.5% every 2 to 3 breaths until 5% was attained for sevoflurane, or 3% for isoflurane. Vecuronium was administered to facilitate tracheal intubation. After intubation, sevoflurane was set to 2% while isoflurane was set to 1% with nitrous oxide with oxygen (1:1) for 5 min. RESULTS: Both sevoflurane and isoflurane provoked a decrease in blood pressure, total power, the low frequency component (LF), and high frequency component (HF) of HRV. Although the heart rate increased during isoflurane anaesthesia, it decreased under sevoflurane. The power of LF and HF also decreased in both groups. LF was higher in the isoflurane group while HF was higher in the sevoflurane group. The LF/HF ratio increased transiently in the isoflurane group, but decreased in the sevoflurane group. CONCLUSION: Anaesthesia induction with isoflurane-nitrous oxide transiently increased cardiac sympathetic activity, while sevoflurane-nitrous oxide decreased both cardiac sympathetic and parasympathetic activities. The balance of cardiac parasympathetic/sympathetic activity was higher in sevoflurane anaesthesia. PMID- 27689430 TI - Anaphylaxis and cardiac surgery for hypertrophic obstructive cardiomyopathy: a case report and review of anaesthetic management. AB - BACKGROUND: The aim of this paper is to describe clinical management in a situation where patient has experienced anaphylaxis while undergoing surgical septal myectomy for hypertrophic obstructive cardiomyopathy (HOCM). CASE REPORT: A 40-yr-old female was scheduled to undergo surgical septal myectomy for the treatment of HOCM. After induction, the patient developed refractory hypotension that did not respond to escalating doses of vasopressors and volume therapy. Although a clinical examination led to the diagnosis of anaphylaxis, epinephrine, which is the usual treatment of choice, failed to improve the patient's haemodynamics. A transesophageal echocardiography revealed a worsening of left ventricular outflow tract obstruction (LVOTO) after epinephrine administration. In the end, the rapid institution of a cardiopulmonary bypass was required as a rescue therapy instead of to save a patient. CONCLUSION: The anaesthetic goals in a patient in HOCM are to maintain preload and afterload and to avoid stimulation of inotropy and chronotropy to leading to left ventricular outflow obstruction. In a patient with anaphylaxis, maintaining these haemodynamic goals becomes much more difficult since the pathophysiology and usual treatment of choice will worsen LVOTO. Special consideration for the need to have extracorporeal life support to treat refractory hypotension in surgical patients with HOCM may be warranted.

AB - Catalytic synthesis of nonracemic P-chiral phosphine derivatives remains a significant challenge. Here we report Cu-catalyzed enantioselective arylation of secondary phosphine oxides with diaryliodonium salts for the synthesis of tertiary phosphine oxides with high enantiomeric excess. The new process is demonstrated on a wide range of substrates and leads to products that are well established P-chiral catalysts and ligands. PMID- 27689433 TI - Piperitone Profiling in Fine Red Bordeaux Wines: Geographical Influences in the Bordeaux Region and Enantiomeric Distribution. AB - Piperitone was recently identified in red Bordeaux wines, and this study was designed to further explore its contribution to wine aroma. Firstly, a geographical origin effect was detected within the Bordeaux region (left versus right banks of the Gironde estuary), with significantly higher mint aroma intensities and piperitone levels in wines from the left bank (Medoc appellations). Statistical analysis of chemical and sensory data highlighted a correlation with the proportion of Cabernet Sauvignon in the wine blends. Accordingly, it was suggested that these sensory and chemical differences may be of varietal origin. Secondly, the contribution of piperitone to minty aromas in the aging bouquet was confirmed by combining both sensory and chemical data from a wide range of red Bordeaux wines. Subsequent investigation of the enantiomeric distribution of piperitone found a significantly higher proportion of the (+) (6S) enantiomeric form in wines displaying a strong aging bouquet. PMID- 27689434 TI - Cabergoline or bromocriptine for prolactinoma? AB - Cabergoline and bromocriptine are among the most commonly used drugs to treat prolactinoma. Cabergoline is a long-acting dopamine receptor agonist which might offer advantages over bromocriptine. However, it is not clear if this translates into clinical benefits. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified two systematic reviews including 12 studies addressing the question of this article, including five randomized controlled trials. We combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded cabergoline is more effective than bromocriptine in resolution of amenorrhea/oligomenorrhea and galactorrhea, it probably increases pregnancy rate, and it is associated to less adverse effects. It is not clear whether cabergoline is also more effective with respect to tumor growth because the certainty of the evidence is very low. PMID- 27689435 TI - Specific premature epigenetic aging of cartilage in osteoarthritis. AB - Osteoarthritis (OA) is a disease affecting multiple tissues of the joints in the elderly, but most notably articular cartilage. Premature biological aging has been described in this tissue and in blood cells, suggesting a systemic component of premature aging in the pathogenesis of OA. Here, we have explored epigenetic aging in OA at the local (cartilage and bone) and systemic (blood) levels. Two DNA methylation age-measures (DmAM) were used: the multi-tissue age estimator for cartilage and bone; and a blood-specific biomarker for blood. Differences in DmAM between OA patients and controls showed an accelerated aging of 3.7 years in articular cartilage (95% CI = 1.1 to 6.3, P = 0.008) of OA patients. By contrast, no difference in epigenetic aging was observed in bone (0.04 years; 95% CI = -1.8 to 1.9, P = 0.3) and in blood (-0.6 years; 95% CI = -1.5 to 0.3, P = 0.2) between OA patients and controls. Therefore, premature epigenetic aging according to DNA methylation changes was specific of OA cartilage, adding further evidence and insight on premature aging of cartilage as a component of OA pathogenesis that reflects damage and vulnerability.

AB - Chemical analysis of small extracellular vesicles (sEVs) circulating in body fluids holds potentials in noninvasive diagnosis of diseases and evaluation of therapeutic treatments. However, quantification of sEVs remains a challenge due to lacking of cost-effective analytical protocols. Herein we report a facile method based on size exclusion chromatography with fluorescence detection (SEC FD) for sEVs quantification. After removal of cells and cell debris, a 0.50 mL sample (e.g., cell culture medium) is incubated with CM-Dil dye to fluorescently label sEVs. The incubation solution is then separated on a SEC column packed with Sepharose CL-4B. The eluent is monitored fluorescently at Ex553 nm/Em570 nm by using a fluorometer equipped with a 50-MUL flow through cuvette. Separation efficiency of the proposed SEC-FD method was evaluated by analyzing 100 nm liposomes and albumin-FITC conjugate. Liposomes were eluted out in less than 6 min, about 10 min before albumin-FITC. A separation repeatability (RSD in retention time) of 1.4% (n = 5) was obtained for liposomes. In analysis of cell culture media, linear calibration curves based on SEC-FD peak height versus sEVs concentration were obtained with r2 value of 0.996. Intraday quantification repeatability (RSD in peak height) was 3.2% (n = 5). The detection limit was estimated to be 2.9 * 107 exosome particles/mL. The proposed assay was applied to the first study of sEVs secretion from TK6 cells cultured in serum-free medium for a culturing period from 1 to 48 h.

AB - An extensive sampling campaign was undertaken to study the levels, isomer profiles and riverine mass discharges of perfluoroalkyl acids (PFAAs) and fluorinated alternatives in 19 Chinese rivers. The levels and homologue profiles of Sigma10PFAAs varied considerably among the 19 rivers (mean 106; median 16.3, range 8.9-1240 ng/L), indicating the influence of specific point sources. Highly branched isomer profiles of perfluorooctanoic acid (18-25% br-PFOA) in rivers with elevated concentrations (96-352 ng/L) indicate that releases during production of PFOA by electrochemical fluorination and/or its use in fluoropolymer manufacture were the dominant sources to these rivers. The fluorinated alternatives 6:2 fluorotelomer sulfonate (detection frequency 21%, < 0.1-3.1 ng/L) and chlorinated polyfluoroalkyl ether sulfonate F-53B (51%, < 0.56 78.5 ng/L) were also found in some rivers. The total Chinese riverine mass discharges of PFOA (mean 80.9; range 16.8-168 t/y) (including monitoring data from this and other studies) were in good agreement with theoretical PFOA emission estimates (17.3-203 t/y) whereas riverine mass discharges of PFOS (mean 3.6; range 1.9-5.6 t/y) could only account for a minor fraction of theoretically estimated PFOS releases (70 t/y). This study provides empirical evidence that emissions from Chinese point sources likely dominate the global emissions of several legacy PFASs (notably PFOA) and fluorinated alternatives (e.g., F-53B). PMID- 27689438 TI - Computational Exploration of the Li-Electrode|Electrolyte Interface in the Presence of a Nanometer Thick Solid-Electrolyte Interphase Layer. AB - A nanometer thick passivation layer will spontaneously form on Li-metal in battery applications due to electrolyte reduction reactions. This passivation layer in rechargeable batteries must have "selective" transport properties: blocking electrons from attacking the electrolytes, while allowing Li+ ion to pass through so the electrochemical reactions can continue. The classical description of the electrochemical reaction, Li+ + e -> Li0, occurring at the Li metal|electrolyte interface is now complicated by the passivation layer and will reply on the coupling of electronic and ionic degrees of freedom in the layer. This passivation layer is called "solid electrolyte interphase (SEI)" and is considered as "the most important but the least understood in rechargeable Li-ion batteries," partly due to the lack of understanding of its structure-property relationship. Predictive modeling, starting from the ab initio level, becomes an important tool to understand the nanoscale processes and materials properties governing the interfacial charge transfer reaction at the Li metal|SEI|electrolyte interface. Here, we demonstrate pristine Li-metal surfaces indeed dissolve in organic carbonate electrolytes without the SEI layer. Based on joint modeling and experimental results, we point out that the well-known two layer structure of SEI also exhibits two different Li+ ion transport mechanisms. The SEI has a porous (organic) outer layer permeable to both Li+ and anions (dissolved in electrolyte), and a dense (inorganic) inner layer facilitate only Li+ transport. This two-layer/two-mechanism diffusion model suggests only the dense inorganic layer is effective at protecting Li-metal in electrolytes. This model suggests a strategy to deconvolute the structure-property relationships of the SEI by analyzing an idealized SEI composed of major components, such as Li2CO3, LiF, Li2O, and their mixtures. After sorting out the Li+ ion diffusion carriers and their diffusion pathways, we design methods to accelerate the Li+ ion conductivity by doping and by using heterogonous structure designs. We will predict the electron tunneling barriers and connect them with measurable first cycle irreversible capacity loss. Finally, we note that the SEI not only affects Li+ and e- transport, but it can also impose a potential drop near the Li metal|SEI interface. Our challenge is to fully describe the electrochemical reactions at the Li-metal|SEI|electrolyte interface. This will be the subject of ongoing efforts.

AB - Over the last two decades, intensive research efforts have been devoted to the suppressions of photoluminescence (PL) blinking and Auger recombination in metal chalcogenide nanocrystals (NCs), with significant progresses being made only very recently in few specific NC structures. Here we show that nonblinking PL is readily available in the newly synthesized perovskite CsPbI3 NCs and that their Auger recombination of charged excitons is greatly slowed down, as signified by a PL lifetime about twice shorter than that of neutral excitons. Moreover, spectral diffusion is completely absent in single CsPbI3 NCs at the cryogenic temperature, leading to a resolution-limited PL line width of ~200 MUeV. PMID- 27689440 TI - Multisynergistic Platform for Tumor Therapy by Mild Microwave Irradiation Activated Chemotherapy and Enhanced Ablation. AB - Microwave (MW) therapy, as a promising type of thermal therapy, has been attracting more and more attention from scientists. The combination of thermal and chemotherapy is of great significance in the latest studies of synergistic tumor therapy. However, the research on the MW therapy mechanism, especially the nonthermal effect applied in the combined cancer therapy, is not thorough enough. Pleasantly, we have discovered that nonthermal MW irradiation can promote the cellular uptake of nanoparticles and anticancer drugs via experiments in vitro and in vivo. Therefore, multifunctional nanoplatforms have been designed for enhanced tumor inhibition by loading ionic liquids (ILs), doxorubicin hydrochloride (DOX), and phase change materials (PCMs) into ZrO2 hollow nanoparticles. PCMs act as MW switches. The as-made IL-DOX-PCM@ZrO2 nanoplatforms were injected into H22-tumor-bearing mice via the tail vein. Mild microwave irradiation (0.9 W, 450 MHz) was then applied. The thermal effect of MW could cause the temperature of the tumor site to rise (58 degrees C). On the other hand, it will trigger the MW switch to open and release DOX when the temperature is high enough. At the same time as drug release, a MW nonthermal effect could improve the cellular uptake of nanomaterials and anticancer drugs. The multisynergistic effect can promote the survival rate of the IL-DOX-PCM@ZrO2+MW group to 100%. The results of the tumor therapy experiment in vivo demonstrated that as-made multifunctional IL-DOX-PCM@ZrO2 nanoplatforms could enhance the therapeutic outcome of combined thermal and chemotherapy under mild MW irradiation. PMID- 27689441 TI - Enhanced Radiosensitization of Gold Nanospikes via Hyperthermia in Combined Cancer Radiation and Photothermal Therapy. AB - Metallic nanostructures as excellent candidates for nanosensitizers have shown enormous potentials in cancer radiotherapy and photothermal therapy. Clinically, a relatively low and safe radiation dose is highly desired to avoid damage to normal tissues. Therefore, the synergistic effect of the low-dosed X-ray radiation and other therapeutic approaches (or so-called "combined therapeutic strategy") is needed. Herein, we have synthesized hollow and spike-like gold nanostructures by a facile galvanic replacement reaction. Such gold nanospikes (GNSs) with low cytotoxicity exhibited high photothermal conversion efficiency (eta = 50.3%) and had excellent photostability under cyclic near-infrared (NIR) laser irradiations. We have demonstrated that these GNSs can be successfully used for in vitro and in vivo X-ray radiation therapy and NIR photothermal therapy. For the in vitro study, colony formation assay clearly demonstrated that GNS mediated photothermal therapy and X-ray radiotherapy reduced the cell survival fraction to 89% and 51%, respectively. In contrast, the cell survival fraction of the combined radio- and photothermal treatment decreased to 33%. The synergistic cancer treatment performance was attributable to the effect of hyperthermia, which efficiently enhanced the radiosensitizing effect of hypoxic cancer cells that were resistant to ionizing radiation. The sensitization enhancement ratio (SER) of GNSs alone was calculated to be about 1.38, which increased to 1.63 when the GNS treatment was combined with the NIR irradiation, confirming that GNSs are effective radiation sensitizers to enhance X-ray radiation effect through hyperpyrexia. In vivo tumor growth study indicated that the tumor growth inhibition (TGI) in the synergistically treated group reached 92.2%, which was much higher than that of the group treated with the GNS-enhanced X-ray radiation (TGI = 29.8%) or the group treated with the GNS-mediated photothermal therapy (TGI = 70.5%). This research provides a new method to employ GNSs as multifunctional nanosensitizers for synergistic NIR photothermal and X-ray radiation therapy in vitro and in vivo. PMID- 27689443 TI - Master Equation Analysis of Thermal and Nonthermal Microwave Effects. AB - Master equation is a successful model to describe the conventional heating reaction, it is expanded to capture the "microwave effect" in this work. The work equation of "microwave effect" included master equation presents the direct heating, indirect heating, and nonthermal effect about the microwave field. The modified master equation provides a clear physics picture to the nonthermal microwave effect: (1) The absorption and the emission of the microwave, which is dominated by the transition dipole moment between two corresponding states and the intensity of the microwave field, provides a new path to change the reaction rate constants. (2) In the strong microwave field, the distribution of internal states of the molecules will deviate from the equilibrium distribution, and the system temperature defined in the conventional heating reaction is no longer available. According to the general form of "microwave effect" included master equation, a two states model for unimolecular dissociation is proposed and is used to discuss the microwave nonthermal effect particularly. The average rate constants can be increased up to 2400 times for some given cases without the temperature changed in the two states model. Additionally, the simulation of a model system was executed using our State Specified Master Equation package. Three important conclusions can be obtained in present work: (1) A reasonable definition of the nonthermal microwave effect is given in the work equation of "microwave effect" included master equation. (2) Nonthermal microwave effect possibly exists theoretically. (3) The reaction rate constants perhaps can be changed obviously by the microwave field for the non-RRKM and the mode-specified reactions.

AB - A periodic array of nanoholes was fabricated via the self-assembly of a polystyrene(PS)-b-poly(methyl methacrylate) (PMMA) block copolymer (BCP) on a silicon substrate and selective etching of the PMMA moieties. Silver nanorods (AgNRs) were then selectively deposited in the nanoholes by a galvanic displacement reaction where the pattern was hexagonally aligned according to the template. The diameter of AgNRs was controlled by changing the immersion time. Optical measurements of the AgNR arrays revealed that the extinction peak was split into two because of the electromagnetically induced transparency effect. In addition, the AgNR arrays showed a surface-enhanced Raman scattering response and were successfully transferred from a silicon substrate to a transparent and flexible polymer film while retaining the rod arrangement. PMID- 27689444 TI - Phosphatidylserine Allows Observation of the Calcium-Myristoyl Switch of Recoverin and Its Preferential Binding. AB - Recoverin undergoes a calcium-myristoyl switch during visual phototransduction. Indeed, calcium binding by recoverin results in the extrusion of its myristoyl group, which allows its membrane binding. However, the contribution of particular lipids and of specific amino acids of recoverin in its membrane binding has not yet been demonstrated. In the present work, the affinity of recoverin for the negatively charged phosphatidylserine has been clearly shown to be governed by a cluster of positively charged residues located in its N-terminal segment. Moreover, the calcium-myristoyl switch of recoverin was only observed upon binding onto monolayers of phosphatidylserine and not in the case of other anionic phospholipids. Fluorescence microscopy experiments with mixed lipid monolayers allowed confirmation of the specific binding of myristoylated recoverin to phosphatidylserine, whereas the extent of penetration of recoverin in phosphatidylserine monolayers was estimated by ellipsometry. A model has thus been proposed for the membrane binding of myristoylated recoverin in the presence of calcium. PMID- 27689445 TI - A Water-Soluble Cationic Zinc Lysine Precursor for Coating ZnO on Biomaterial Surfaces. AB - A novel water-soluble cationic zinc lysine coordination compound, [Zn[(C6H14N2O2)]2Cl]Cl.2H2O (1), has been designed and synthesized and its crystal structure determined. The aqueous solution of this coordination compound is not only transparent and stable at room temperature but it is also nearly neutral (pH ~ 7). It is worth noting that zinc oxide (ZnO) forms in situ upon dilution of a solution of the compound. The bioactivity of ZnO has been confirmed using an Alarma Blue assay. These unique properties allow the coordination compound to gently grow ZnO coating with excellent antibacterial benefits onto biomaterial surfaces in a facile and safe manner.

AB - Seven tetracoordinate organoboron fluorophores with heterobiaryl N,O- or N,N chelate ligands were prepared and photophysically characterized (in toluene). The electronic variation of the heteroaromatic moiety provided a means for the fine tuning of the UV/vis absorption and emission spectra. In the most interesting cases, the spectra were red-shifted to maximum absorbance at wavelengths longer than 500 nm and emission maxima between 620 and 660 nm. The pronounced intramolecular charge-transfer character of the dyes yielded large Stokes shifts (3500-5100 cm-1), while maintaining appreciable fluorescence quantum yields of up to 0.2 for emission maxima longer than 600 nm. The lipophilic character of the dyes enabled their application as stains of vesicle substructures in confocal fluorescence microscopy imaging.

AB - Using Monte Carlo simulations, we have investigated the dynamic phase transition properties of magnetic nanoparticles with ferromagnetic core coated by an antiferromagnetic shell structure. Effects of field amplitude and frequency on the thermal dependence of magnetizations, magnetization reversal mechanisms during hysteresis cycles, as well as on the exchange bias and coercive fields have been examined, and the feasibility of applying dynamic magnetic fields on the particle have been discussed for technological and biomedical purposes. PMID- 27689448 TI - State-of-the-Art Thermochemical and Kinetic Computations for Astrochemical Complex Organic Molecules: Formamide Formation in Cold Interstellar Clouds as a Case Study. AB - We describe an integrated computational strategy aimed at providing reliable thermochemical and kinetic information on the formation processes of astrochemical complex organic molecules. The approach involves state-of-the-art quantum-mechanical computations, second-order vibrational perturbation theory, and kinetic models based on capture and transition state theory together with the master equation approach. Notably, tunneling, quantum reflection, and leading anharmonic contributions are accounted for in our model. Formamide has been selected as a case study in view of its interest as a precursor in the abiotic amino acid synthesis. After validation of the level of theory chosen for describing the potential energy surface, we have investigated several pathways of the OH + CH2NH and NH2 + H2CO reaction channels. Our results show that both reaction channels are essentially barrierless (in the sense that all relevant transition states lie below or only marginally above the reactants) and once tunneling is taken into the proper account indicate that the reaction can occur under the low temperature conditions of interstellar environments.

PMID- 27689450 TI - Theoretical Foundation for Electric-Dipole-Allowed Chiral-Specific Fluorescence Optical Rotary Dispersion (F-ORD) from Interfacial Assemblies. AB - Fluorescence optical rotary dispersion (F-ORD) is proposed as a novel chiral specific and interface-specific spectroscopic method. F-ORD measurements of uniaxial assemblies are predicted to be fully electric-dipole-allowed, with corresponding increases in sensitivity to chirality relative to chiral-specific measurements in isotropic assemblies that are commonly interpreted through coupling between electric and magnetic dynamic dipoles. Observations of strong chiral sensitivity in prior single-molecule fluorescence measurements of chiral interfacial molecules are in excellent qualitative agreement with the predictions of the F-ORD mechanism and challenging to otherwise explain. F-ORD may provide methods to suppress background fluorescence in studies of biological interfaces, as the detected signal requires both polar local order and interfacial chirality. In addition, the molecular-level descriptions of the mechanisms underpinning F ORD may also potentially apply to aid in interpreting chiral-specific Raman and surface-enhanced Raman spectroscopy measurements of uniaxially oriented assemblies, opening up opportunities for chiral-specific and interface-specific vibrational spectroscopy. PMID- 27689452 TI - Financial Burden Secondary to Delay in Cholecystectomy Following Mild Biliary Pancreatitis. AB - AIM OF THE STUDY: The guidelines recommend that patients with mild gallstones pancreatitis should undergo a definitive management for gallstones during the same admission or within the next two weeks. The aim of this study was to estimate the financial cost resulting from a delay in surgical management following mild gallstones pancreatitis. This includes the costs of readmissions with biliary events and the subsequent investigations required during these admissions. MATERIALS AND METHODS: A retrospective analysis included patients with gallstone pancreatitis who were admitted to a district general hospital in the United Kingdom over one year. Patients with severe pancreatitis and those unfit for surgery were excluded. RESULTS: Forty patients were included in the study, 27 females (67%) and 13 males (33%). Mean age was 50.2 years. Twenty-two patients of the total presented with a single admission with gallstone pancreatitis prior to an elective surgery; however, 18 patients (45%) required recurrent admissions. The duration between the first admission and surgery ranged from 14 to 389 days (median of 99 days). Only one patient (2.5%) had cholecystectomy within two weeks of admission as per guidelines. Twenty-two ultrasound scans, four computed tomography scans, 15 magnetic resonance cholangiopancreatography, and two endoscopic retrograde cholangiopancreatography were the total of the extra-investigations required during readmissions. Estimated costs of extra admissions and extra investigations exceeded L33,000. CONCLUSIONS: The delay in cholecystectomy for patients admitted with mild gallstone pancreatitis and fit for surgery has resulted in high readmission rate with biliary events, and subsequently high extrax costs. PMID- 27689451 TI - Delivery of bevacizumab to atheromatous porcine carotid tissue using echogenic liposomes. AB - Ultrasound is both a valuable diagnostic tool and a promoter of beneficial tissue bioeffects for the treatment of cardiovascular disease. Vascular effects can be mediated by mechanical oscillations of circulating microbubbles that may also encapsulate and shield therapeutic agents in the bloodstream. Here, the effect of color-Doppler ultrasound exposure on bevacizumab-loaded liposome delivery into the vascular bed was assessed in atheromatous porcine carotids. Bevacizumab, an anti-angiogenic antibody to vascular endothelial growth factor (VEGF-A), was loaded into echogenic liposomes (BEV-ELIP) and confirmed to be immunoreactive. BEV-ELIP flowing within the lumen were exposed to color-Doppler ultrasound at three acoustic pressures for 3.5 min during treatment at physiologic temperature and fluid pressure. To confirm the presence of bubble activity, cavitation was detected within the lumen by a single-element passive cavitation detector. After treatment, the artery was fixed at physiologic pressure and subjected to immunohistochemical analysis to assess the penetration of bevacizumab within the carotid wall. The results suggest that other factors may more strongly influence the deposition of bevacizumab into carotid tissue than color-Doppler ultrasound and cavitation. In both sets of arteries, preferential accumulation of bevacizumab occurred in locations associated with atheroma progression and neointimal thickening: fibrous tissue, necrotic plaque and areas near macrophage infiltration. The delivery of bevacizumab to carotid vascular tissue correlated with the properties of the tissue bed, such as permeability, or affinity for growth-factor binding. Future investigations using this novel therapeutic strategy may focus on characterizing the spatial extent of delivery and bevacizumab colocalization with biochemical markers of atheroma. PMID- 27689453 TI - Concomitant Medication Use and New-Onset Diabetes Among Medicaid Beneficiaries with Chronic Obstructive Pulmonary Disease. AB - Use of multiple prescription medications is common among individuals with chronic obstructive pulmonary disease (COPD) because of coexisting inflammatory-related conditions. Specifically, the use of antidepressants, inhaled corticosteroids (ICSs), and statins may place individuals with COPD at high risk for new-onset diabetes. The objective was to examine the relationship between the use of antidepressants, ICSs, and statins and new-onset diabetes among Medicaid beneficiaries with COPD. This study used a retrospective longitudinal cohort design using multiple years (2005-2008) of Medicaid claims for beneficiaries with newly diagnosed COPD (n = 15,287), who were diabetes free at baseline. National Drug Codes were used to determine the receipt of antidepressants, ICSs, and statins, and International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to define new-onset diabetes (250.x2). Multivariable logistic regression was used to examine the adjusted relationship between medication use and new-onset diabetes. Overall, 6.3% of the study population was diagnosed with new-onset diabetes. After controlling for baseline characteristics, individuals using ICSs (adjusted odds ratio [AOR]: 1.23; 95% confidence interval [CI]: 1.07, 1.47) or statins (AOR: 1.48; 95% CI: 1.27, 1.72) had a greater risk of new-onset diabetes compared to those not given ICSs, statins, or antidepressants. Analyses using combined medication categories revealed that adults using statins in combination with both antidepressants and ICSs, or when combined with ICS, were more likely to have new-onset diabetes. These findings indicate that multiple medication use (ICSs and statins) was associated with increased rates of new-onset diabetes. Further research is warranted to understand this association. PMID- 27689454 TI - PulseRider-assisted treatment of wide-necked intracranial bifurcation aneurysms: safety and feasibility study. AB - OBJECTIVE The goal of this study was to assess the safety and feasibility of PulseRider, a novel endovascular stent, in the treatment of intracranial bifurcation aneurysms with wide necks. The authors present the initial results of the first 10 cases in which the PulseRider device was used. METHODS Patients whose aneurysms were intended to be treated with the PulseRider device at 2 institutions in the United Kingdom were identified prospectively. Patient demographics, procedural details, immediate neurological and clinical status, and immediate angiographic outcomes and 6-month clinical and imaging follow-up were recorded prospectively. RESULTS At the end of the procedure, all 10 patients showed complete aneurysm occlusion (Raymond Class 1). There were no significant intraprocedural complications except for an occurrence of thromboembolism without clinical sequelae. There was no occurrence of aneurysm rupture or vessel dissection. At 6-month follow-up, 7 and 3 patients had modified Rankin Scale scores of 0 and 1, respectively. All 10 patients had stable aneurysm occlusion (Raymond Class 1) and daughter vessel intraluminal patency on 6-month follow-up catheter angiography. CONCLUSIONS The authors' early experience with the PulseRider device demonstrates that it is a safe and effective adjunct in the treatment of bifurcation aneurysms with wide necks arising at the middle cerebral artery bifurcation, anterior cerebral artery, basilar apex, and carotid terminus. It works by providing a scaffold at the neck of the bifurcation aneurysm, enabling neck remodeling and coil support while maintaining parent vessel intraluminal patency. Early clinical and radiological follow-up showed good functional outcome and stable occlusion rates, respectively. Further data are needed to assess medium- and long-term outcomes with PulseRider.

PMID- 27689458 TI - The force pyramid: a spatial analysis of force application during virtual reality brain tumor resection. AB - OBJECTIVE Virtual reality simulators allow development of novel methods to analyze neurosurgical performance. The concept of a force pyramid is introduced as a Tier 3 metric with the ability to provide visual and spatial analysis of 3D force application by any instrument used during simulated tumor resection. This study was designed to answer 3 questions: 1) Do study groups have distinct force pyramids? 2) Do handedness and ergonomics influence force pyramid structure? 3) Are force pyramids dependent on the visual and haptic characteristics of simulated tumors? METHODS Using a virtual reality simulator, NeuroVR (formerly NeuroTouch), ultrasonic aspirator force application was continually assessed during resection of simulated brain tumors by neurosurgeons, residents, and medical students. The participants performed simulated resections of 18 simulated brain tumors with different visual and haptic characteristics. The raw data, namely, coordinates of the instrument tip as well as contact force values, were collected by the simulator. To provide a visual and qualitative spatial analysis of forces, the authors created a graph, called a force pyramid, representing force sum along the z-coordinate for different xy coordinates of the tool tip. RESULTS Sixteen neurosurgeons, 15 residents, and 84 medical students participated in the study. Neurosurgeon, resident and medical student groups displayed easily distinguishable 3D "force pyramid fingerprints." Neurosurgeons had the lowest force pyramids, indicating application of the lowest forces, followed by resident and medical student groups. Handedness, ergonomics, and visual and haptic tumor characteristics resulted in distinct well-defined 3D force pyramid patterns. CONCLUSIONS Force pyramid fingerprints provide 3D spatial assessment displays of instrument force application during simulated tumor resection. Neurosurgeon force utilization and ergonomic data form a basis for understanding and modulating resident force application and improving patient safety during tumor resection. PMID- 27689459 TI - The effects of new or worsened postoperative neurological deficits on survival of patients with glioblastoma. AB - OBJECTIVE An increased extent of resection (EOR) has been shown to improve overall survival of patients with glioblastoma (GBM) but has the potential for causing a new postoperative neurological deficit. To investigate the impact of surgical neurological morbidity on survival, the authors performed a retrospective analysis of the clinical data from patients with GBM to quantify the impact of a new neurological deficit on the survival benefit achieved with an increased EOR. METHODS The data from all GBM patients who underwent resection at the University of Florida from 2010 to 2015 with postoperative imaging within 72 hours of surgery were included in the study. Retrospective analysis was performed on clinical outcomes and tumor volumes determined on postoperative and follow-up imaging examinations. RESULTS Overall, 115 patients met the inclusion criteria for the study. Tumor volume at the time of presentation was a median of 59 cm3 (enhanced on T1-weighted MRI scans). The mean EOR (+/- SD) was 94.2% +/- 8.7% (range 59.9%-100%). Almost 30% of patients had a new postoperative neurological deficit, including motor weakness, sensory deficits, language difficulty, visual deficits, confusion, and ataxia. The neurological deficits had resolved in 41% of these patients on subsequent follow-up examinations. The median overall survival was 13.1 months (95% CI 10.9-15.2 months). Using a multipredictor Cox model, the authors observed that increased EOR was associated with improved survival except for patients with smaller tumor volumes (<= 15 cm3). A residual volume of 2.5 cm3 or less predicted a favorable overall survival. Developing a postoperative neurological deficit significantly affected survival (9.2 months compared with 14.7 months, p = 0.02), even if the neurological deficit had resolved by the first follow-up. However, there was a trend of improved survival among patients with resolution of a neurological deficit by the first follow-up compared with patients with a permanent neurological deficit. Any survival benefit from achieving a 95% EOR was abrogated by the development of a new neurological deficit postoperatively. CONCLUSIONS Developing a new neurological deficit after resection of GBM is associated with a decrease in overall survival. A careful balance between EOR and neurological compromise needs to be taken into account to reduce the likelihood of neurological morbidity from surgery. PMID- 27689460 TI - A rare case of central nervous system amyloidoma treated with fractionated radiotherapy. AB - A 54-year-old female presented with multiple episodes of emesis, intractable headaches, worsening balance, and slowly progressive right facial weakness. Imaging demonstrated a 3-cm mass in the left internal capsule and corona radiata region with associated edema, mass effect, and midline shift concerning for high grade glioma, lymphoma, or brain metastasis. Stereotactic biopsy of the mass was consistent with amyloid deposition. Systemic workup for amyloidosis was negative, and the mass was thought to represent a focal tumor-like deposit of amyloid, also referred to as "amyloidoma." In the absence of systemic disease, therapy, which can include surgery or radiotherapy, can be directed at the local process. The location of the patient's lesion was not amenable to resection; therefore, she was treated with fractionated radiotherapy of 30.6 Gy at 1.8 Gy per fraction. Serial brain MRI demonstrated stability 18 months out from therapy. To the authors' knowledge, this is the first documented case of focal fractionated radiotherapy for CNS amyloidoma. The authors concluded that radiotherapy can prevent further progression of amyloidomas in anatomical locations that prohibit resection. PMID- 27689462 TI - Occipital transtentorial/falcine approach, a "cross-court" trajectory to accessing contralateral posterior thalamic lesions: case report. AB - Surgical treatment of lesions in the posterior thalamus, especially those extending laterally, is technically challenging because of a deep surgical field, narrow operative corridor, and the surrounding critical neurovascular structures. The authors describe an occipital transtentorial/falcine approach (OTFA) that was successfully used in the treatment of a cavernous malformation (CM) extending laterally from thalamus to midbrain. A 40-year-old man complained of progressive right hemiparesis and numbness. Radiological evaluation revealed a large CM in the left thalamus, surfacing on the pulvinar thalami, and extending 4 cm laterally from the midline. In addition to the usual procedures of a right-sided occipital transtentorial approach, the authors incised the falx cerebri to expand the operative corridor to the left thalamus. They achieved generous exposure of the left thalamus through a "cross-court" oblique trajectory while avoiding excessive retraction on the occipital lobe. The CM was completely removed, and no newly developed or worsening deficits were detected postoperatively. To better understand the OTFA and its application, the authors performed a cadaveric dissection. The OTFA provides increased exposure of the posterior thalamus without cortical incision and facilitates lateral access to this area through the "cross-court" operative corridor. This approach adds to the armamentarium for neurosurgeons treating thalamic lesions.

In this multicenter study, the authors review outcomes of cerebellar AVMs after stereotactic radiosurgery (SRS). METHODS Eight medical centers contributed data from 162 patients with cerebellar AVMs managed with SRS. Of these patients, 65% presented with hemorrhage. The median maximal nidus diameter was 2 cm. Favorable outcome was defined as AVM obliteration and no posttreatment hemorrhage or permanent radiation-induced complications (RICs). Patients were followed clinically and radiographically, with a median follow-up of 60 months (range 7 325 months). RESULTS The overall actuarial rates of obliteration at 3, 5, 7, and 10 years were 38.3%, 74.2%, 81.4%, and 86.1%, respectively, after single-session SRS. Obliteration and a favorable outcome were more likely to be achieved in patients treated with a margin dose greater than 18 Gy (p < 0.001 for both), demonstrating significantly better rates (83.3% and 79%, respectively). The rate of latency preobliteration hemorrhage was 0.85%/year. Symptomatic post-SRS RICs developed in 4.5% of patients (n = 7). Predictors of a favorable outcome were a smaller nidus (p = 0.0001), no pre-SRS embolization (p = 0.003), no prior hemorrhage (p = 0.0001), a higher margin dose (p = 0.0001), and a higher maximal dose (p = 0.009). The Spetzler-Martin grade was not found to be predictive of outcome. The Virginia Radiosurgery AVM Scale score (p = 0.0001) and the Radiosurgery-Based AVM Scale score (p = 0.0001) were predictive of a favorable outcome. CONCLUSIONS SRS results in successful obliteration and a favorable outcome in the majority of patients with cerebellar AVMs. Most patients will require a nidus dose of higher than 18 Gy to achieve these goals. Radiosurgical and not microsurgical scales were predictive of clinical outcome after SRS. PMID- 27689463 TI - Association between shunt-responsive idiopathic normal pressure hydrocephalus and alcohol. AB - OBJECTIVE Idiopathic normal pressure hydrocephalus (iNPH) is characterized by ventriculomegaly, gait difficulty, incontinence, and dementia. The symptoms can be ameliorated by CSF drainage. The object of this study was to identify factors associated with shunt-responsive iNPH. METHODS The authors reviewed the medical records of 529 patients who underwent shunt placement for iNPH at their institution between July 2001 and March 2015. Variables associated with shunt responsive iNPH were identified using bivariate and multivariate analyses. Detailed alcohol consumption information was obtained for 328 patients and was used to examine the relationship between alcohol and shunt-responsive iNPH. A computerized patient registry from 2 academic medical centers was queried to determine the prevalence of alcohol abuse among 1665 iNPH patients. RESULTS Bivariate analysis identified associations between shunt-responsive iNPH and gait difficulty (OR 4.59, 95% CI 2.32-9.09; p < 0.0001), dementia (OR 1.79, 95% CI 1.14-2.80; p = 0.01), incontinence (OR 1.77, 95% CI 1.13-2.76; p = 0.01), and alcohol use (OR 1.98, 95% CI 1.23-3.16; p = 0.03). Borderline significance was observed for hyperlipidemia (OR 1.56, 95% CI 0.99-2.45; p = 0.054), a family history of hyperlipidemia (OR 3.09, 95% CI 0.93-10.26, p = 0.054), and diabetes (OR 1.83, 95% CI 0.96-3.51; p = 0.064). Multivariate analysis identified associations with gait difficulty (OR 3.98, 95% CI 1.81-8.77; p = 0.0006) and alcohol (OR 1.94, 95% CI 1.10-3.39; p = 0.04). Increased alcohol intake correlated with greater improvement after CSF drainage. Alcohol abuse was 2.5 times more prevalent among iNPH patients than matched controls. CONCLUSIONS Alcohol consumption is associated with the development of shunt-responsive iNPH.

PMID- 27689465 TI - Relationship of A1 segment hypoplasia to anterior communicating artery aneurysm morphology and risk factors for aneurysm formation. AB - OBJECTIVE Hypoplasia of the A1 segment of the anterior cerebral artery is frequently observed in patients with anterior communicating artery (ACoA) aneurysms. The effect of this anatomical variant on ACoA aneurysm morphology is not well understood. METHODS Digital subtraction angiography images were reviewed for 204 patients presenting to the authors' institution with either a ruptured or an unruptured ACoA aneurysm. The ratio of the width of the larger A1 segment to the smaller A1 segment was calculated. Patients with an A1 ratio greater than 2 were categorized as having A1 segment hypoplasia. The relationship of A1 segment hypoplasia to both patient and aneurysm characteristics was then assessed. RESULTS Of 204 patients that presented with an ACoA aneurysm, 34 (16.7%) were found to have a hypoplastic A1. Patients with A1 segment hypoplasia were less likely to have a history of smoking (44.1% vs 62.9%, p = 0.0410). ACoA aneurysms occurring in the setting of a hypoplastic A1 were also found to have a larger maximum diameter (mean 7.7 vs 6.0 mm, p = 0.0084). When considered as a continuous variable, increasing A1 ratio was associated with decreasing aneurysm dome-to-neck ratio (p = 0.0289). There was no significant difference in the prevalence of A1 segment hypoplasia between ruptured and unruptured aneurysms (18.9% vs 10.7%; p = 0.1605). CONCLUSIONS Our results suggest that a hypoplastic A1 may affect the morphology of ACoA aneurysms. In addition, the relative lack of traditional risk factors for aneurysm formation in patients with A1 segment hypoplasia argues for the importance of hemodynamic factors in the formation of ACoA aneurysms in this anatomical setting. PMID- 27689467 TI - Problem Features versus Algorithm Performance on Rugged Multiobjective Combinatorial Fitness Landscapes. AB - In this article, we attempt to understand and to contrast the impact of problem features on the performance of randomized search heuristics for black-box multiobjective combinatorial optimization problems. At first, we measure the performance of two conventional dominance-based approaches with unbounded archive on a benchmark of enumerable binary optimization problems with tunable ruggedness, objective space dimension, and objective correlation ([Formula: see text]MNK-landscapes). Precisely, we investigate the expected runtime required by a global evolutionary optimization algorithm with an ergodic variation operator (GSEMO) and by a neighborhood-based local search heuristic (PLS), to identify a ([Formula: see text]approximation of the Pareto set. Then, we define a number of problem features characterizing the fitness landscape, and we study their intercorrelation and their association with algorithm runtime on the benchmark instances. At last, with a mixed-effects multilinear regression we assess the individual and joint effect of problem features on the performance of both algorithms, within and across the instance classes defined by benchmark parameters. Our analysis reveals further insights into the importance of ruggedness and multimodality to characterize instance hardness for this family of multiobjective optimization problems and algorithms. PMID- 27689468 TI - Performance Analysis of Continuous Black-Box Optimization Algorithms via Footprints in Instance Space. AB - This article presents a method for the objective assessment of an algorithm's strengths and weaknesses. Instead of examining the performance of only one or more algorithms on a benchmark set, or generating custom problems that maximize the performance difference between two algorithms, our method quantifies both the nature of the test instances and the algorithm performance. Our aim is to gather information about possible phase transitions in performance, that is, the points in which a small change in problem structure produces algorithm failure. The method is based on the accurate estimation and characterization of the algorithm footprints, that is, the regions of instance space in which good or exceptional performance is expected from an algorithm. A footprint can be estimated for each algorithm and for the overall portfolio. Therefore, we select a set of features to generate a common instance space, which we validate by constructing a sufficiently accurate prediction model. We characterize the footprints by their area and density. Our method identifies complementary performance between algorithms, quantifies the common features of hard problems, and locates regions where a phase transition may lie. PMID- 27689466 TI - Activation of estrogen receptor alpha by estradiol and cisplatin induces platinum resistance in ovarian cancer cells. AB - Activation of Estrogen receptor (ER) alpha (alpha) promotes cell growth and influences the response of cancer cell to chemotherapeutic agents. However, the mechanism by which ERalpha activation antagonizes cells to chemotherapy-induced cytotoxicity remains unclear. Here, we investigated the effect of cisplatin on ERalpha activation. In addition, we examined whether down-regulation of ERalpha modulate cisplatin-mediated cytotoxicity using 2 human ovarian cancer cells (Caov 3 and Ovcar-3) transduced with ERalpha short hairpin RNA (shRNA). The proliferation assay showed that 17beta-estradiol (E2) induced cell proliferation via activation of Akt and extracellular signal-regulated kinase (ERK) cascades, while shRNA mediated downregulation of ERalpha inhibited the cell proliferation. Immunoblot analysis revealed that cisplatin induced the phosphorylation of ERalpha at serine 118 via ERK cascade. Luciferase assay showed that cisplatin increases transcriptional activity of estrogen-responsive element (ERE). The E2 stimulated ERalpha activation attenuated cisplatin-induced cytotoxicity. Meanwhile, down-regulation of ERalpha inhibited E2-induced protective effect on cisplatin toxicity as determined by 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) assays. Moreover, Pretreatment with E2 followed by cisplatin decreased the expression of cleaved PARP, and increased the expression of anti-apoptotic protein Bcl-2. Collectively, our findings suggest that activation of ERalpha by E2 and cisplatin can induce platinum-resistance by increasing the expression of anti-apoptotic protein in ovarian cancer cells. Therefore, our findings provide valuable information that ERalpha might be a promising therapeutic target for platinum-resistant ovarian cancer. PMID- 27689469 TI - ? PMID- 27689470 TI - Normobaric Hypoxia Effects on Balance Measured by Computerized Dynamic Posturography. AB - : Wagner, Dale R., Skyler Saunders, Brady Robertson, and John E. Davis. Normobaric hypoxia effects on balance measured by computerized dynamic posturography. High Alt Med Biol. 17:222-227, 2016.-Background/Aim: Equilibrium was measured by computerized dynamic posturography at varying levels of normobaric hypoxia before and after exercise. METHODS: Following a familiarization trial, 12 males (27.3 +/- 7.1 years) completed three sessions in random order on a NeuroCom SMART Balance Master: a sham trial at the ambient altitude of 1500 m and simulated altitudes of 3000 and 5000 m created by a hypoxic generator. The NeuroCom provided composite scores for a sensory organization test of equilibrium and a motor control test to assess the appropriate motor response. Additional information on somatosensory, visual, and vestibular responses was obtained. Each session consisted of 20 minutes of rest followed by the NeuroCom test, then 10 minutes of exercise, and 10 minutes of recovery followed by a second NeuroCom test, all while connected to the hypoxic generator. Mean differences were identified with a two-way (pre/postexercise and altitude condition), repeated-measures analysis of variance. RESULTS: The composite sensory score was significantly lower (p < 0.001) during the 5000 m trial (73.4 +/- 12.0) compared to the 1500 m (80.8 +/- 7.0) and 3000 m (84.1 +/- 5.0) altitudes. The inability to ignore inaccurate visual cues in a situation of visual conflict was the most common sensory error. Motor control was not affected by altitude or exercise. DISCUSSION: These results suggest that moderate hypoxia does not affect balance, but severe hypoxia significantly reduces equilibrium. Furthermore, it appears that the alterations in equilibrium are primarily from impairments in visual function.

PMID- 27689474 TI - Phthalates exposure indicators determined by urinary phthalate metabolites in healthy non-obese Czech adults: FANTOM study. AB - It is assumed that human exposure to phthalates may be associated with adverse health effects. The indicators of urinary phthalate metabolite concentrations in healthy adults are limited. In this study, the phthalate metabolites concentrations were detected from 24-h urine collection in non-obese Czech adults (n = 201). Each participant filled in an 80-item questionnaire (FANTOM-SQ 2013) regarding the outdoor and indoor sources of phthalates, the use of personal care products and food intake sources. The concentrations of 15 phthalates metabolites were analysed following enzymatic cleavage of the glucuronide using ultra-high performance liquid chromatography-electrospray ionisation tandem mass spectrometry (UHPLC-ESI-MS/MS). The indicators of chronic or acute exposure phthalate-containing materials were identified. It is shown that higher fruit consumption was positively and significantly associated with a higher level of total 15 urinary phthalates biomarkers (p < 0.001). Regular meat consumption showed a negative significant association with total 15 phthalates metabolites (p < 0.01). The use of personal care products was significantly and positively correlated with monoethyl phthalate urine concentrations (p < 0.05). The analysis of the dietary behaviour and personal care products use in the Czech non-obese population showed it to be a predictable tool in the level of phthalates exposure when high fruit consumption and personal care products use are linked to higher phthalate metabolite contents in the urine. However, this topic deserves more research. PMID- 27689473 TI - Altered microRNA expression profiles in lung damage induced by nanosized SiO2. AB - The objective of the present research is to explore miRNAs expression profiles in lung tissue of rat treated by nanosized SiO2 in the light of normal at diverse dosages, time, predict their target genes, and probe the biological function and regulation of miRNA in the lung damage process caused by nanosized SiO2. Up regulation of rno-miR-208, rno-miR-212 and rno-miR-18a in lung tissue mainly characterized by inflammation of SD rats caused by nanosized SiO2 particles instilled intratracheally at 7th, 15th 30th d using Illumina HiSeq2000 sequencing technique and were further verified by quantitative reverse transcriptase polymerase chain reaction (qRT PCR) assay. Lung damage is mainly with characteristics of lung interstitial fibrosis, upregulation of rno-miR-212, rno miR-144, rno-miR-702-3p, rno-miR-379 and rno-miR-127, down-regulation of rno-miR 541 at 60th, 90th d post-exposure. As target genes of rno-miR-208, rno-miR-212 and rno-miR-18a respectively, there was no statistical significance of programmed cell death 4 (PDCD4), LIN28B and connective tissue growth factor (CTGF) mRNA expression level (P > 0.05) compared to beta-actin as internal controls detected by Real-time quantitative PCR. The differences in protein gray value ratio of PDCD4, LIN28B and CTGF detected by Western blotting test were statistically significant (P < 0.05). These results suggested that miR-208, miR-212 and miR-18a may take effects in rats' lung damage lead by nanosized SiO2. Their target genes of PDCD4, LIN28B and CTGF functioned in translation level of target genes in regulation of inflammatory signaling pathways and involved in the formation of tissue fibrosis. PMID- 27689475 TI - CDO1 promoter methylation is associated with gene silencing and is a prognostic biomarker for biochemical recurrence-free survival in prostate cancer patients. AB - Molecular biomarkers may facilitate the distinction between aggressive and clinically insignificant prostate cancer (PCa), thereby potentially aiding individualized treatment. We analyzed cysteine dioxygenase 1 (CDO1) promoter methylation and mRNA expression in order to evaluate its potential as prognostic biomarker. CDO1 methylation and mRNA expression were determined in cell lines and formalin-fixed paraffin-embedded prostatectomy specimens from a first cohort of 300 PCa patients using methylation-specific qPCR and qRT-PCR. Univariate and multivariate Cox proportional hazards and Kaplan-Meier analyses were performed to evaluate biochemical recurrence (BCR)-free survival. Results were confirmed in an independent second cohort comprising 498 PCa cases. Methylation and mRNA expression data from the second cohort were generated by The Cancer Genome Atlas (TCGA) Research Network by means of Infinium HumanMethylation450 BeadChip and RNASeq. CDO1 was hypermethylated in PCa compared to normal adjacent tissues and benign prostatic hyperplasia (P < 0.001) and was associated with reduced gene expression (rho = -0.91, P = 0.005). Using two different methodologies for methylation quantification, high CDO1 methylation as continuous variable was associated with BCR in univariate analysis (first cohort: HR = 1.02, P = 0.002, 95% CI [1.01-1.03]; second cohort: HR = 1.02, P = 0.032, 95% CI [1.00-1.03]) but failed to reach statistical significance in multivariate analysis. CDO1 promoter methylation is involved in gene regulation and is a potential prognostic biomarker for BCR-free survival in PCa patients following radical prostatectomy. Further studies are needed to validate CDO1 methylation assays and to evaluate the clinical utility of CDO1 methylation for the management of PCa. PMID- 27689476 TI - Healthy Futures Program and Adolescent Sexual Behaviors in 3 Massachusetts Cities: A Randomized Controlled Trial. AB - OBJECTIVES: We evaluated the impact of the 3-year Healthy Futures program on reducing sexual behaviors among middle school students. METHODS: Fifteen public middle schools in Haverhill, Lowell, and Lynn, Massachusetts, participated in this longitudinal school-cluster randomized controlled trial (2011-2015), which included 1344 boys and girls. We collected student survey data at baseline, immediately after each Nu-CULTURE curriculum (classroom component of Healthy Futures) in the sixth, seventh, and eighth grades, and at a 1-year follow-up in the ninth grade (cohort 1 students only). RESULTS: Healthy Futures did not reduce the overall prevalence of eighth-grade students who reported ever having vaginal sex. In the eighth-grade follow-up, fewer girls in the treatment group than in the control group reported ever having vaginal sex (P = .04), and fewer Hispanic treatment students than Hispanic control students reported ever having vaginal sex (P = .002). CONCLUSIONS: There was some evidence of delaying sexual initiation by the end of Nu-CULTURE, for girls and Hispanics, but not for boys. Future research should focus on improving implementation of the supplemental components intended to foster interpersonal and environmental protective factors associated with sustained delays in sexual activity. PMID- 27689477 TI - Culturally Responsive Adolescent Pregnancy and Sexually Transmitted Infection Prevention Program for Middle School Students in Hawai'i. AB - OBJECTIVES: To evaluate the effectiveness of Pono Choices, a culturally responsive adolescent pregnancy and sexually transmitted infection (STI) prevention program targeting middle school youths in Hawai'i. METHODS: We conducted a cluster randomized controlled trial with the school as the unit of random assignment over 3 semesters between 2012 and 2013. The sample consisted of 36 middle schools and 2203 students. We administered student surveys to collect baseline outcomes, student demographic data, and outcomes at 12 months after baseline. RESULTS: We found statistically significant effects for the knowledge assessment, which focused on basic understanding of adolescent pregnancy and STI prevention. The average percentage of correct responses was 73.6 for the treatment group and 60.4 for the control group (P < .001). We did not find statistically significant effects on behavioral outcomes (initiation of sexual activity or engagement in high-risk sexual behavior) or on other nonbehavioral outcomes (attitudes, skills, intentions). CONCLUSIONS: Pono Choices had a statistically significant impact on knowledge of adolescent pregnancy and STI prevention among middle school students at 12 months after baseline, though it did not lead to detectable changes in behavioral outcomes within the 1-year observation period. These results call for an exploration of longer-term outcomes to assess effects on knowledge retention and behavioral changes.

(a text message intervention) intensified the effects of the adolescent pregnancy prevention Teen Outreach Program (control) for youths. METHODS: In this trial performed in Denver, Colorado, from 2011 to 2014, we randomized 8 Boys & Girls Clubs each of 4 years into 32 clubs per year combinations to ensure each club would serve as a treatment site for 2 years and a control site for 2 years. Control intervention consisted of the Teen Outreach Program only. We enrolled 852 youths (aged 14-18 years), and 632 were retained at follow-up, with analytic samples ranging from 50 to 624 across outcomes. We examined program costs, and whether the intervention increased condom and contraceptive use, access to care, and pregnancy prevention. RESULTS: Control program costs were $1184 per participant, and intervention costs were an additional $126 per participant (+10.6%). There were no statistically significant differences in primary outcomes for the full sample. Hispanic participants in the intervention condition had fewer pregnancies at follow-up (1.79%) than did those in the control group (6.72%; P = .02). CONCLUSIONS: Youth All Engaged is feasible, low cost, and could have potential benefits for Hispanic youths. PMID- 27689479 TI - Impacts of an Enhanced Family Health and Sexuality Module of the HealthTeacher Middle School Curriculum: A Cluster Randomized Trial. AB - OBJECTIVES: To evaluate the impacts of an enhanced version of the Family Life and Sexuality Module of the HealthTeacher middle school curriculum. METHODS: We conducted a cluster randomized trial of Chicago, Illinois, middle schools. We randomly assigned schools to a treatment group that received the intervention during the 2010-2011 school year or a control group that did not. The primary analysis sample included 595 students (7 schools) in the treatment group and 594 students (7 schools) in the control group. RESULTS: Students in the treatment schools reported greater exposure to information on reproductive health topics such as sexually transmitted infections (STIs; 78% vs 60%; P < .01), abstinence (64% vs 37%; P < .01), and birth control (45% vs 29%; P < .01). They also reported higher average scores on an index of knowledge of contraceptive methods and STI transmission (0.5 vs 0.3; P = .02). We found no statistically significant differences in rates of sexual intercourse (12% vs 12%; P = .99), oral sex (12% vs 9%; P = .18), or other intermediate outcomes. CONCLUSIONS: The program had modest effects when tested among Chicago middle school students.

AB - OBJECTIVES: To investigate the impact of Be the Exception, a newly developed program to delay onset of sexual behaviors, in a White, rural population. METHODS: A cluster randomized controlled trial in northwestern Indiana (14 schools, 1776 students, 2011-2015) compared an intervention (5 group sessions and multimedia assembly) with a no-intervention group; both continued usual standard health education. Multilevel mixed-effects logistic regressions with 1455 students measured long-term outcomes 12 months after baseline questionnaire. RESULTS: Intervention group students reported ever having had sexual intercourse and sexual intercourse in past 3 months significantly less often than did the comparison group (1.91% vs 6.29% and 1.09% vs 4.26%, respectively). No statistical differences were observed for reported sexual intercourse in past 3 months with risky behavior (1.23% vs 2.24%), without condom use (1.04% vs 1.73%), or without birth control (1.00% vs 1.53%). Cumulatively, intervention group students significantly more often reported no activity, holding hands, hugging and kissing and less often reported touching above and below the waist, other sex, or sexual intercourse. CONCLUSIONS: Be the Exception is effective in delaying the onset of sexual behavior among rural middle school students.

AB - OBJECTIVES: To determine if the Teen Outreach Program (TOP), a youth development and service learning program, can reduce sexual risk-taking behaviors compared with a business as usual or benign counterfactual. METHODS: We synthesized results of 5 independent studies conducted in 5 geographically and ethnically diverse locations between 2011 and 2015 with 17 194 middle and high school students. Each study cluster-randomized classes, teachers, or schools to treatment or control groups and included the students enrolled in those clusters at baseline in an intent-to-treat analysis. Multilevel models tested impacts on recent sexual activity, recent unprotected sexual activity, and sexual initiation among the sexually inexperienced at baseline at approximately 1 and 2 years after baseline. RESULTS: Precision-weighted average effect sizes showed nonsignificant reductions of 1 percentage point or less in recent sexual activity (5 studies: 0.6; P = .32), recent unprotected sex (5 studies: -0.2; P = .76), and sexual initiation (4 studies: -1.1; P = .10) after 1 year. CONCLUSIONS: There was little evidence of the effectiveness of TOP in reducing sexual risk-taking behaviors. Results underscored the importance of continually evaluating evidence based programs that have previously been shown to be effective. PMID- 27689491 TI - Randomized Trials of the Teen Outreach Program in Louisiana and Rochester, New York. AB - OBJECTIVES: To evaluate the Teen Outreach Program, a pregnancy prevention program, in 2 community-based settings. METHODS: We evaluated the Teen Outreach Program, a 9-month positive youth development program, in 3 cohorts of youths from 2012 to 2015 in 2 states. In Louisiana, 7 agencies participated in an individualized randomized controlled trial, with youths randomly assigned to a treatment or control condition. Fourteen agencies in Rochester, New York, participated in a cluster randomized controlled trial. RESULTS: We found no differences between the intervention and control youths on delay of sexual onset in Louisiana (adjusted odds ratio [AOR] = 0.80; 95% confidence interval [CI] = 0.62, 1.03) or in Rochester, New York (AOR = 0.89; 95% CI = 0.45, 1.77), or for sex with no effective means of birth control (Louisiana, AOR = 1.18; 95% CI = 0.78, 1.78; Rochester, AOR = 0.41; 95% CI = 0.13, 1.27) after controlling for relevant covariates. CONCLUSIONS: We found no short-term effects for the offer of the intervention. Research might be needed for the long-term and intermediate impacts of youth development programs on these and other adolescent risk behaviors. PMID- 27689492 TI - Replicating Reducing the Risk: 12-Month Impacts of a Cluster Randomized Controlled Trial. AB - OBJECTIVES: To test the effectiveness of Reducing the Risk, an evidence-based sexual health curriculum designed to help prevent adolescent pregnancy and sexually transmitted infections, on youth sexual behavior and intermediate outcomes thought to lead to these behaviors. METHODS: Classes within schools in St. Louis, Missouri; Austin, Texas; and San Diego, California; were randomly assigned to receive Reducing the Risk or "business as usual." Youths completed Web-based surveys at baseline (preintervention, August 2012-January 2014) and 12 months later (August 2013-January 2015). Intent-to-treat analyses were conducted across sites; we tested for differences in impacts between sites and other subgroups. RESULTS: The program had no overall impact on sexual behaviors. However, at 1 site, program participants were significantly less likely to have engaged in recent sexual intercourse than were control group members. There were positive overall impacts on intermediate outcomes (e.g., knowledge, attitudes). CONCLUSIONS: After 12 months, Reducing the Risk was unsuccessful at changing sexual behaviors. Other results were mixed, but promising evidence (e.g., behavioral impacts at 1 site, impacts on intermediate outcomes) suggests potential for more widespread behavioral impacts over a longer term.

AB - OBJECTIVES: To test the effects of the Safer Sex Intervention (SSI) on female adolescents' sexual behavior and possible antecedents of behavior such as sexual health attitudes, knowledge, motivation, intentions, and skills. METHODS: A randomized controlled trial compared SSI (n = 1196) with no intervention (n = 613) among female adolescents aged 13 to 20 years at 3 sites across the United States from 2012 to 2015. Intent-to-treat impacts were estimated at 9 months after baseline, overall, and for key subgroups. RESULTS: Compared with control participants, SSI participants were less likely to have sexual intercourse without birth control, more likely to report positive attitudes toward protection and intention to use condoms, and more confident of their ability to refuse sex. SSI did not affect sexual risk knowledge or motivation to delay childbearing. Positive impacts on sexual behavior and sexual risk were observed among key subgroups of youths who were aged 18 years or older, Hispanic, not sexually experienced at baseline, and enrolled at the Minnesota site. CONCLUSIONS: SSI produced meaningful changes in sexual behavior and sexual risk and successfully addressed some potential antecedents of sexual risk behavior.

PMID- 27689496 TI - It's Your Game...Keep It Real in South Carolina: A Group Randomized Trial Evaluating the Replication of an Evidence-Based Adolescent Pregnancy and Sexually Transmitted Infection Prevention Program. AB - OBJECTIVES: To evaluate the effectiveness of an evidence-based HIV/sexually transmitted infection (STI)/pregnancy prevention program for middle schools implemented by school staff in South Carolina. METHODS: Twenty-four schools, representing 3143 youths, participated in a randomized trial from 2011 to 2014. Students completed surveys before programming (fall of seventh grade), after completing the 2-year It's Your Game...Keep It Real program (spring of eighth grade), and 1-year postprogram (spring of ninth grade). RESULTS: There was no statistically significant effect on initiation of vaginal sex between baseline and eighth grade. Significantly fewer students in the comparison condition reported initiating sex at ninth grade, relative to the intervention condition. No group differences existed on other behavioral outcomes that addressed sexual activity in the past 3 months at ninth grade. Seven of 26 psychosocial outcomes (3 knowledge, 1 attitude, 1 self-efficacy, 2 personal limits) were positively affected at eighth grade; 4 remained significant at ninth grade. CONCLUSIONS: The original studies' behavioral effects were not replicated in this population, possibly as a result of this being an effectiveness trial instead of an efficacy trial, counterfactual exposure design issues, or postprogram exposure to evidence based programming.

PMID- 27689498 TI - Replicating !Cuidate!: 6-Month Impact Findings of a Randomized Controlled Trial. AB - OBJECTIVES: To test whether !Cuidate!, a program culturally adapted for Hispanic youths, affects sexual risk behavior. METHODS: We evaluated 3 replications of !Cuidate! in California, Arizona, and Massachusetts in a randomized controlled trial (registry no. NCT02540304) in which 2169 primarily Hispanic participants were randomly assigned to an intervention (n = 1326) or a control (n = 870) group. Youths were surveyed at baseline (September 2012-April 2014) and 6 months postbaseline (March 2013-October 2014). We estimated pooled and subgroup impacts using a regression framework with baseline covariates to increase statistical precision (1216 youths analyzed in the treatment group, 806 analyzed in the control group). RESULTS: We found no impacts on the study's primary outcomes of recent sexual activity or recent unprotected sexual activity. However, !Cuidate! improved knowledge (10%-20% increase; P < .001), attitudes (effect size = .24; P < .001), and skills (effect size = .14; P = .002). Exploratory subgroup analyses suggest potentially problematic effects for some groups. CONCLUSIONS: Findings suggest that !Cuidate! was effective in improving youths' knowledge and attitudes. However, after 6 months, these changes did not translate to improvements in reported sexual risk behaviors.

AB - OBJECTIVES: To replicate an evidence-based HIV risk reduction program and assess its impact on 2 behavioral outcomes-inconsistency of condom use and frequency of sex-6 months after the program. METHODS: The study was an individual-level randomized controlled trial in which we randomly assigned 850 youths (aged 14-18 years) to 1 of 2 conditions. The treatment (Becoming a Responsible Teen) is a group-level sociocognitive and skills training sexual education course; the control is a general health intervention that includes the same initial informational component as the treatment. Participants were recruited over 3 summers (2012-2014) from a summer employment program in New Orleans, Louisiana, that serves primarily African American adolescents. RESULTS: Six months after program exposure, we found no statistically significant difference between treatment and control group members' self-reported inconsistency of condom use or frequency of sex (P > .05). CONCLUSIONS: Although previous evidence has indicated that this particular program can be effective, this study's findings indicate that it was not effective in this setting with this specific population. Results should provide an incentive to learn why the intervention works in some cases and what conditions are necessary for causal impacts.

AB - OBJECTIVES: To test the efficacy of Reducing the Risk (RTR) and Love Notes (LN) on reducing risky sexual behavior among youths yet to experience or cause a pregnancy. METHODS: The four dependent variables were ever had sex, condom use, birth control use, and number of sexual partners at 3- and 6-month follow-up in a 3-arm cluster randomized controlled trial of 1448 impoverished youths, aged 14 to 19 years, in 23 community-based organizations in Louisville, Kentucky, from September 2011 through March 2014. RESULTS: At 3 and 6 months, compared with the control condition, youths in RTR reported fewer sexual partners and greater use of birth control. At 6 months, LN participants reported greater use of birth control and condoms, fewer sexual partners, and were less likely to have ever had sex compared with the control condition. CONCLUSIONS: We provided additional evidence for the continued efficacy of RTR and the first rigorous study of LN, which embeds sex education into a larger curriculum on healthy relationships and violence prevention.

PMID- 27689502 TI - A Clustered Randomized Controlled Trial of the Positive Prevention PLUS Adolescent Pregnancy Prevention Program. AB - OBJECTIVES: To determine the impact of Positive Prevention PLUS, a school-based adolescent pregnancy prevention program on delaying sexual intercourse, birth control use, and pregnancy. METHODS: I randomly assigned a diverse sample of ninth grade students in 21 suburban public high schools in California into treatment (n = 2483) and control (n = 1784) groups that participated in a clustered randomized controlled trial. Between October 2013 and May 2014, participants completed baseline and 6-month follow-up surveys regarding sexual behavior and pregnancy. Participants in the treatment group were offered Positive Prevention PLUS, an 11-lesson adolescent pregnancy prevention program. RESULTS: The program had statistically significant impacts on delaying sexual intercourse and increasing the use of birth control. However, I detected no program effect on pregnancy rates at 6-month follow-up. CONCLUSIONS: The Positive Prevention PLUS program demonstrated positive impacts on adolescent sexual behavior. This suggests that programs that focus on having students practice risk reduction skills may delay sexual activity and increase birth control use. PMID- 27689503 TI - Preventing Pregnancy in High School Students: Observations From a 3-Year Longitudinal, Quasi-Experimental Study. AB - OBJECTIVES: To assess whether a sexual health education intervention reduces pregnancy rates in high school students. METHODS: We performed a secondary analysis of a 3-year quasi-experimental study performed in South Texas from 2011 to 2015 in which 1437 students without a history of pregnancy at baseline were surveyed each fall and spring. Potentially confounding risk factors considered included sexual behaviors, intentions, and demographics. The outcome measure was self-reported pregnancy status for male and female students. We performed analyses for male and female students using separate discrete time-to-event models. RESULTS: We found no difference in pregnancy rates between intervention and comparison students within the first 3 years of high school. Female and male students in the intervention groups had pregnancy hazard ratios of, respectively, 1.62 (95% CI = 0.9, 2.61; P = .1) and 0.78 (95% CI = 0.44, 1.48; P = .4) relative to the comparison groups. CONCLUSIONS: The educational intervention had no impact on the pregnancy rate. Social media tools in pregnancy prevention programs should be adaptive to new technologies and rapidly changing adolescent preferences for these services. PMID- 27689504 TI - Cementless hip implants: an expanding choice. AB - INTRODUCTION: Total hip replacement is a successful procedure with long survival records compared to other joint arthroplasties. Cemented implants have been available for many years, however the complications associated with loosening and, ultimately, failure over time has led to the development of cementless stems and implants.The ideal prosthesis should recreate a biomechanically normal hip joint, allow pain-free function and last the patient's life span without requiring revision. Optimal results with uncemented femoral stems rely on obtaining initial stability, osseointegration, biological fixation, and uniform stress transfer to the proximal bone.There are a multitude of factors that can affect the integration, stability and fixation of these stems into bone, and understanding these factors is the key to choosing the appropriate implant for a specific femur. METHODS: This article aims to discuss cementless prostheses based on evidence-based practice. Geometry, roughness, stem coating, technique and bone quality are among the factors discussed. This was achieved through a review of the current literature. CONCLUSIONS: Uncemented femoral stems have shown good, long-term survivorship and functional outcome, with promising results in younger patients.Limitations in the current literature make it difficult to assess and compare different designs to determine optimal indications for each type.Biological fixation, in which the prosthesis is directly fixed to the bone, is the preferred fixation method.Future studies of cementless implants should consistently address patient age, activity level, bone type, and deformities so that more definitive conclusions can be drawn about when to use each design. PMID- 27689505 TI - Noise characteristics in ceramic-on-ceramic vs. metal-on-polyethylene total hip arthroplasty: a comparative study. AB - INTRODUCTION: A comparison of noise in ceramic-on-ceramic (CoC) bearings and metal-on-polyethylene (MoP) bearings after total hip arthroplasty (THA) was undertaken. Noise associated with MoP implants is rarely reported and has not been linked to squeaking. METHODS: A noise characterising hip questionnaire and Oxford Hip Score (OHS) was sent to 1,000 THA patients; there were 509 respondents 282 CoC and 227 MoP; mean age 63.7 years (range 45-92 years), mean follow up 33 months (range 6-156 months). RESULTS: Of 282 repsondents 47 (17%) of the CoC patients reported noise compared to 19 (8%) of the MoP patients (p = 0.048); 9 CoC patients and 4 MoP patients reported squeaking. Overall, 27% patients with noise reported avoiding recreational activities because of it and patients with noisy hips scored on average 5 points less on the OHS (CoC: p = 0.04 and MoP: p = 0.007). DISCUSSION: This is the first study to report squeaking from MoP THAs. The squeaking hip phenomenon is not exclusive to CoC THAs. Noisy hip implants may have social implications, and patients should be aware of this. We have shown a relationship between noise and a lower OHS. However, longer follow-up is needed to link noise to a poorly functioning implant.

AB - Deamidation of glutamine (Gln) residues is a spontaneous or enzymatic process with significant implications in aging and human pathology. Although some methods are available to identify the gamma/alpha-glutamyl products of deamidation, none of these methods allows the characterization of this post-translational modification (PTM) from complex biological samples by shotgun proteomics. Here we present LERLIC-MS/MS, a chromatographic strategy that uses a long (50 cm) anion exchange capillary column operating in the electrostatic repulsion-hydrophilic interaction mode (ERLIC) and coupled directly to tandem mass spectrometry (MS/MS) for proteome analysis in a single injection. Profiling of soluble extracts of brain tissues by LERLIC-MS/MS distinguished for the first time gamma/alpha glutamyl isomers of deamidation, encountering a 1.7 gamma/alpha-glutamyl ratio for most Gln deamidation products. A detailed analysis of any deviation from that observed ratio allowed the identification of transglutaminase-mediated gamma glutamyl isomers as intermediate products of transamidation. Furthermore, LERLIC MS/MS was able to simultaneously separate Gln and asparagine (Asn) deamidation products even for those peptides showing multiple deamidated proteoforms. The characterization of Asn deamidated residues by LERLIC-MS/MS also uncovered novel PIMT (protein L-isoaspartyl methyltransferase) substrate proteins in human brain tissues that deviated from the expected 3:1 isoAsp/Asp ratio. Taken together, our results demonstrate that LERLIC-MS/MS can be used to perform an in-depth study of protein deamidation on a global proteome scale. This new strategy should help to elucidate the biological implications of deamidation in aging and disease conditions. PMID- 27689509 TI - Job control, work-family balance and nurses' intention to leave their profession and organization: A comparative cross-sectional survey. AB - BACKGROUND: The shortage of nurses is a problem in many countries. In Japan, the distribution of nurses across different care settings is uneven: the shortage of nurses in home healthcare and nursing homes is more serious than in hospitals. Earlier research has identified numerous factors affecting nurses' intention to leave work (e.g., job control, family-related variables, work-family conflict); however, these factors' levels and effect size may vary between nurses in hospitals, home healthcare, and nursing homes. OBJECTIVES: This study measured job control, family-related variables, and work-family conflict among nurses in hospitals, home healthcare, and nursing homes, and compared these variables' levels and effect size on nurses' intention to leave their organization or profession between these care settings. DESIGN: The research design was cross sectional. METHODS: Participating nurses from hospitals, home healthcare facilities, and nursing homes self-administered an anonymous questionnaire survey; nurses were recruited from the Kyushu district of Japan. Nurses from nine hospitals, 86 home healthcare offices, and 107 nursing homes participated. We measured nurses' intention to leave nursing or their organization, perceived job control, family variables and work-family conflict. We analyzed 1461 participants (response rate: 81.7%). RESULTS: The level of job control, family variables, and work-family conflict affecting nurses varied between hospitals, home healthcare, and nursing homes; additionally, these variables' effect on nurses' intention to leave their organization or profession varied between these care settings. Work family conflict, family variables, and job control most strongly predicted nurses' intention to leave their organization or profession in hospitals, home healthcare, and nursing homes, respectively. CONCLUSIONS: Interventions aiming to increase nurse retention should distinguish between care settings. Regarding hospitals, reducing nurses' work-family conflict will increase nurse retention. Regarding home healthcare, allowing nurses to fulfill family responsibilities will increase nurse retention. Regarding nursing home nurses, increasing nurses' job control will increase nurse retention. PMID- 27689508 TI - College students' perceptions and knowledge of hookah use. AB - PURPOSE: Hookah is an increasingly popular tobacco product among college students. The purpose of this study was to determine if college students are aware of tobacco and nicotine content in hookah, and examine associations between college students' knowledge and perceptions of hookah and their past 30-day hookah use. METHODS: Participants were 5451 young adults attending one of 24 2- and 4-year colleges. Analyses examined if hookah knowledge was uniquely associated with current hookah use, over and above perceptions of harm and addictiveness, number of other tobacco products currently used, and socio demographic factors. Analyses were first conducted for the entire sample and then only for current hookah users. RESULTS: 26.9% of all students believed hookah did not contain tobacco and 38% believed that hookah did not contain nicotine. Students who believed that hookah contained tobacco were at increased odds of hookah use, and those with increased perceptions of harm were at decreased odds of hookah use. However, hookah knowledge was not associated with hookah users' intensity of use. Moreover, although increased perceptions of harm were associated with lower intensity of use among current users, increased perceptions of addictiveness were associated with higher intensity of use. CONCLUSIONS: This study shows gaps in knowledge of hookah contents, and adds to the body of literature, which provides evidence for mandating warning labels as well as tobacco interventions for college students. PMID- 27689510 TI - Synthesis and Application of Organic Phosphonate Salts as Draw Solutes in Forward Osmosis for Oil-Water Separation. AB - The development of suitable draw solution in forward osmosis (FO) process has attracted the growing attention for water treatment purpose. In this study, a series of organic phosphonate salts (OPSs) are synthesized by one-step Mannich like reaction, confirmed by FTIR and NMR characterizations, and applied as novel draw solutes in FO applications. Their solution properties including osmotic pressures and viscosities, as well as their FO performance as a function of the solution concentration are investigated systematically. In FO process, a higher water flux of 47-54 LMH and a negligible reverse solute flux can be achieved in the PRO (AL-DS) mode (active layer faces the draw solution) using a homemade thin film composite membrane (PSF-TFC) and deionized water as the feed solution. Among all OPS draw solutes, the tetraethylenepentamine heptakis(methylphosphonic) sodium salt (TPHMP-Na) exhibits the best FO flux at 0.5 mol/kg concentration, which is further applied for the separation of emulsified oil-water mixture. The recovery of diluted OPS solutions is carried out via a nanofiltration (NF) system with a rejection above 92%. The aforementioned features show the great potential of OPS compounds as a novel class of draw solutes for FO applications. PMID- 27689511 TI - Integrating social and facial models of person perception: Converging and diverging dimensions. AB - Models of first impressions from faces have consistently found two underlying dimensions of trustworthiness and dominance. These dimensions show apparent parallels to social psychological models of inter-group perception that describe dimensions of warmth (cf. trustworthiness) and competence (cf. dominance), and it has been suggested that they reflect universal dimensions of social cognition. We investigated whether the dimensions from face and inter-group social perception models are indeed equivalent by evaluating first impressions of faces. Across four studies with differing methods we consistently found that while perceptions of trustworthiness and warmth were closely related, perceptions of dominance and competence were less strongly related. Taken together, our results demonstrate strong similarity on the first dimension across facial and social models, with less similarity on the second dimension. We suggest that facial impressions of competence and dominance may represent different routes to judging a stranger's capability to help or harm. PMID- 27689512 TI - Comparable rest-related promotion of spatial memory consolidation in younger and older adults. AB - Flexible spatial navigation depends on cognitive mapping, a function that declines with increasing age. In young adults, a brief period of postnavigation rest promotes the consolidation and integration of spatial memories into accurate cognitive maps. We examined (1) whether rest promotes spatial memory consolidation and integration in older adults; and (2) whether the magnitude of the rest benefit changes with increasing age. Young and older adults learned a route through a virtual environment, followed by a 10-minute delay comprising either wakeful rest or a perceptual task, and a subsequent cognitive mapping task, requiring the pointing to landmarks from different locations. Pointing accuracy was lower in the older than younger adults. However, there was a comparable rest-related enhancement in pointing accuracy in the 2 age groups. Together our findings suggest that (1) the age-related decline in cognitive mapping cannot be explained by increased consolidation interference in older adults; and (2) as we grow older, rest continues to support the consolidation and integration of spatial memories. PMID- 27689513 TI - A social network analysis of substance use among immigrant adolescents in six European cities. AB - BACKGROUND: Social integration and the health of adolescents with a migration background is a major concern in multicultural societies. The literature, however, has paid little attention to the wider determinants of their health behaviours, including the composition of their social networks. The aim of this study was to describe the composition of adolescents' social networks according to migration background, and to examine how social networks are associated with substance use. METHOD: In 2013, the SILNE study surveyed 11,015 secondary-school adolescents in 50 schools in six European cities in Belgium, Finland, Germany, Italy, the Netherlands, and Portugal, using a social network design. Each adolescent nominated up to five of their best and closest friends. Migration status was defined as first-generation migrants, second-generation migrants, and speaking another language at home. We computed two groups of network structural positions, the centrality of individual adolescents in networks, and the homophily of their social ties regarding migration (same-migration). Multilevel logistic regression was used to model the association between network structural position and smoking, alcohol use, and cannabis use. RESULTS: Compared with non migrant adolescents, adolescents with migration backgrounds had similar relationship patterns. But almost half their social ties were with same-migration background adolescents; non-migrants had few social ties to migrants. For adolescents with a migration background, a higher proportion of social ties with non-migrants was associated with increased use of cannabis (OR = 1.07, p = 0.03) and alcohol (OR = 1.08, p < 0.01), but not with increased smoking (p = 0.60). Popular migrant adolescents were at less risk of smoking, alcohol use, and cannabis use than popular non-migrant adolescents. CONCLUSION: Homophily of social ties by migration background is noticeable in European schools. The tendency of migrant adolescents to have same-migration social ties may isolate them from non-migrant adolescents, but also reduces their risky health behaviours, in particular cannabis and alcohol use. PMID- 27689514 TI - The second me: Seeing the real body during humanoid robot embodiment produces an illusion of bi-location. AB - Whole-body embodiment studies have shown that synchronized multi-sensory cues can trick a healthy human mind to perceive self-location outside the bodily borders, producing an illusion that resembles an out-of-body experience (OBE). But can a healthy mind also perceive the sense of self in more than one body at the same time? To answer this question, we created a novel artificial reduplication of one's body using a humanoid robot embodiment system. We first enabled individuals to embody the humanoid robot by providing them with audio-visual feedback and control of the robot head movements and walk, and then explored the self-location and self-identification perceived by them when they observed themselves through the embodied robot. Our results reveal that, when individuals are exposed to the humanoid body reduplication, they experience an illusion that strongly resembles heautoscopy, suggesting that a healthy human mind is able to bi-locate in two different bodies simultaneously. PMID- 27689515 TI - Presacral retroperitoneal hematoma after blunt trauma presents with rectal bleeding - A case report. AB - INTRODUCTION: We present a case of a presacral hematoma, which penetrated into the rectum resulting in rectal bleeding. This is an unusual presentation of a presacral hematoma. PRESENTATION OF THE CASE: A 76-year-old woman, using warfarin anticoagulant prophylaxis, presented with a rectal bleed two days after a fall. A sigmoidoscopy revealed that the source of bleeding was a presacral hematoma penetrating into the rectum. A Computed Tomography scan of the pelvis confirmed the presence of a hematoma measuring 10*9.4cm in the presacral space, as well as a fracture of os coccygis. She was transferred to a highly specialized facility, where she was treated conservatively with blood transfusions and repeated endoscopic toilet of the presacral cavity. One month after her initial fall, the patient had fully recovered. DISCUSSION: Rectal bleeding usually causes suspicion of a bleeding in the gastrointestinal tract. In this report the patient's anticoagulant treatment has likely contributed to bleeding and the formation of the hematoma. To our knowledge, this is the first case report of a presacral hematoma acutely penetrating into the rectum and causing lower gastrointestinal bleeding. CONCLUSION: Rectal bleed after trauma, in a patient receiving anticoagulant treatment, should raise suspicion of a penetrating hematoma, and such patients should be managed at highly specialized facilities. PMID- 27689516 TI - Granular cell tumour developing in the background of a previous mandibular giant cell lesion: Case report. AB - INTRODUCTION: Granular cell tumours of the mandible are very rare. We present a unique case which has developed at the site of a previous giant cell lesion. PRESENTATION: 51 year old Caucasian lady had excision of a recurrent giant cell lesion of the anterior mandible. Follow up showed evidence of radiographic recurrence. However, further biopsies from the same site showed granular cell tumour with soft tissues extension. The patient remains well on long term follow up with no evidence of recurrence. DISCUSSION: This case is unique because the granular cell tumour has evolved from the site of a recurrent giant cell lesion. Conservative surgical excision was an adequate treatment option. CONCLUSION: Within the limitations of our case study, a correlation between granular cell tumour and giant cell lesion is possible. However, more research is needed to prove this. PMID- 27689517 TI - Platelet-rich fibrin (PRF) in implant dentistry in combination with new bone regenerative technique in elderly patients. AB - INTRODUCTION: Some studies have demonstrated that platelet rich fibrin (PRF) is a healing biomaterial with a great potential for bone and soft tissue regeneration, without any inflammatory reactions and may be used alone or in combination with bone grafts, promoting hemostasis, bone growth, and maturation. PRF appears as a natural and satisfactory aid in bone regenerative surgery in elderly patients with favorable results and low risks. AIM: This study wants to demonstrate how PRF in association with a new split crest augmentation technique can be a great aid in implant rehabilitation, especially in the elderly patients, when bone regeneration is required. MATERIALS AND METHODS: Ten patients were treated in this study, five following the flapless split crest new procedure and other five patients following traditional procedure without split crest as control. Five patients with an average age between 50 and 60 years were selected to be operated with a split crest flapless modified technique in order to optimize the regenerative conditions with a bone augmentation and implant insertion in one single stage procedure. For all the patients autologous PRF has been used to fill the split crest gap or simply as regenerative material. Orthopantomography, intraoral radiography and CT DentaScan/CT Cone beam were performed for every patient before the treatment and at follow-up time exeption made for CT. RESULTS: All cases were successful, there were no problems at surgery time, at post operative and at osteointegration periods. All implants achieved osteointegration. These results were obtained by accurately managing immediate and late post operative period in all of the operated cases. Mean difference for height bone loss between the two groups of patients was 2.4mm at T1 and 2.2mm at T3. DISCUSSION: The rationale of this split crest flapless modified technique is to obtain a proper buccal cortex expansion preserving its vascular supply avoiding periosteal elevation for better cortical bone nourishing. Moreover, advantages are reported related to the use of PRF. The effectiveness of PRF is shown in promoting the healing of surgical wounds, it has, in fact, platelet growth factors that can improve the vascularisation of the surgical site, promoting neoangiogenesis. Furthermore, by simply changing the settings of the centrifuge, it is possible to obtain a normal gelling if it has to be used as regenerative and stimulating material, or more consistent substance to be used as a filler in the split crest gap. CONCLUSIONS: The main advantages in using the platelet-rich fibrin are healing and bone regenerative properties in combination with its complete resorption after surgery, thus avoiding a second surgery time, important factor in the elderly patients. Currently, it is a minimally invasive technique with low risks and satisfactory clinical results such preventing complications or implant failure particularly in elderly patients for age related conditions. PMID- 27689518 TI - A retained foreign body granuloma mimicking a left ventricular psuedoanuerysm. AB - INTRODUCTION: Gossypiboma, also referred to as a textiloma, gauzoma or muslinoma describe a mass in the body composed of a central cotton core surrounded by a foreign body reaction. It has an estimated incidence of 1/1000-1/10000 surgeries, occurring in the abdomen (56%), pelvis (18%) and least commonly the thorax (11%) and represents an unfortunate event for both the patient and the operating surgeon with severe liability implications. PRESENTATION OF CASE: We report a case of a 49-year-old male with Marfan Syndrome who was admitted to the cardiology department with a four day history of shortness of breath and associated dull, non-radiating chest pain. Past history included a previous Bentall procedure for a type-A aortic dissection and coronary artery bypass grafting involving a saphenous vein graft to the right coronary artery. A computed tomography (CT) scan showed a round, heterogeneous mass measuring 14*9cm with lobulated contours, situated adjacent to the left ventricle along the left posterior region of the aorta. The mass was resected and further dissection revealed a plastic band harboured from the core of the mass. DISCUSSION: The majority of cases of intrathoracic gossypiboma present as intractable cough or an incidental finding on radiological evaluation. Dyspnoea alone is relatively underreported as a presenting symptom of this condition CONCLUSION: This case highlights the important clinical history features for diagnosing this surgical error, including persistent respiratory symptoms and a history of cardio-thoracic surgery. It also emphasizes on the need for implementing definite strategies to prevent the occurrence of gossypiboma in surgical practice. PMID- 27689520 TI - Sigmoid endometriosis in a post-menopausal woman leading to acute large bowel obstruction: A case report. AB - INTRODUCTION: Endometriosis is usually a disease involving women of reproductive age. Colonic endometriosis is a rare sequelae. It usually presents vaguely with nonspecific abdominal pain, dyspareunia, fecal tenesmus, rectal bleeding or painful defecation. There are very few case reports of sigmoid endometriosis in the literature, more so ones involving post-menopausal women. Our report highlights such a case, mimicking a malignant rectosigmoid stricture leading to a large bowel obstruction. CASE PRESENTATION: A 63year old lady was referred by her General Practitioner for further investigation of recent altered bowel habit. She underwent an incomplete colonoscopy due to stricturing in the sigmoid. She subsequently was admitted with abdominal pain, distension and vomiting, with imaging consistent with a large bowel obstruction secondary to a stricturing mass within the rectosigmoid which was suspicious for malignancy. An emergency laparotomy and Hartmann's procedure was performed. She had an uncomplicated post surgical recovery. Histology revealed no underlying malignancy, but confirmed colonic endometriosis. CONCLUSION: This case report shows that colonic endometriosis, although rare, can be significantly infiltrative and lead to complications such as a large bowel obstruction. Diagnosing this condition can be challenging and usually requires histological confirmation. PMID- 27689519 TI - Gastric GIST or gastric schwannoma-A diagnostic dilemma in a young female. AB - INTRODUCTION: Gastrointestinal stromal tumor (GIST) is the commonest mesenchymal tumor of GI tract and 60-70% of it seen in the stomach, whereas Gastric schwannoma is a benign, slow growing and one of the rare neoplasms of stomach. Age distribution, clinical, radiological features and gross appearance of both tumors are similar. PRESENTATION OF CASE: We report a rare case of gastric schwannoma in a 20-year-old girl, who underwent subtotal gastrectomy with the suspicion of a GIST preoperatively but later confirmed to be gastric schwannoma postoperatively after immunohistochemical study. DISCUSSION: Accordingly, the differential diagnosis for gastric submucosal mass should be gastric schwannoma. Furthermore, Gastric schwannoma is a benign neoplasm with excellent prognosis after surgical resection, whereas 10-30% of GIST has malignant behavior. Therefore, it is important to distinguish between gastric schwannoma and GIST so as to make an accurate diagnosis for optimally guide treatment options. CONCLUSION: Due to the paucity of gastric schwannoma, the index of suspicion for this diagnosis is low. So it is important to include gastric schwannoma in the differential diagnosis when preoperative imaging studies reveal submucosal exophytic gastric mass and after resection of the tumor with a negative margin, it should be sent for immunohistochemical study for confirmation of diagnosis. PMID- 27689521 TI - Migration of an intrauterine device to the left inguinal region, the first reported case. AB - INTRODUCTION: A large number of complications are reported with the use of IUD. Migration to inguinal region has not been mentioned in literature. We report a rare case of migrated IUD to inguinal canal. CASE REPORT: A 25-year-old lady presented with a painfull mass in the left inguinal region. Diagnostic work up showed migrated IUD to inguinal region. Operation was done and the impacted IUD with surrounding granuloma was retrieved. DISCUSSION: When the string of the IUD is no longer visible at the external os of the cervix, radiological scan must be performed, this should begin with a sonographic examination and plain abdominal radiography may be used to localize the IUD. CONCLUSION: IUD Migration may occur to unusual area and perforation can be misdiagnosed as non-witnessed expulsion. PMID- 27689522 TI - Angiomyxolipoma of the right sub-brow: Case report with review of the literature. AB - INTRODUCTION: Angiomyxolipoma (AML) is a rare variant of benign lipoma with characteristic histopathological and immuno-histochemical features. It consists of fatty tissue admixed with myxoid stroma and blood vessels. It was first described by Mai et al. in 1996 [1], with a total number of 19 cases reported since. PRESENTATION: This is the first report of an AML in subcutaneous tissue of the face, presenting as a 4-month old cystic lesion in a 78-year old lady. Diagnosis was based on radiological and histopathological with cytochemical findings. DISCUSSION: It is important to distinguish this lesion as distinct from malignant subcutaneous lesions of fatty tissue, especially with short history as seen in our case. CONCLUSION: Precise diagnosis of angiomyxolipoma is important to avoid unnecessary investigations, stress and misdiagnosis of myxoid liposarcoma.

AB - INTRODUCTION: Broncho-esophageal fistula is a rare clinical condition which can be manifested with non-specific signs and symptoms. PRESENTATION OF A CASE: Here, we report an adult case of a broncho-esophageal fistula in a 43-year-old man referred for chronic cough after fluid food intake and weight loss. Barium swallow, esophagogastroduodenoscopy, bronchoscopy and Computed Tomography of the chest demonstrated a broncho-esophageal fistula between the apical segmental bronchus of the lower right lobe and the middle section of the esophagus. The patient underwent video-assisted thoracoscopic surgery for resection of the fistula. No post-operative complications occurred. DISCUSSION: Broncho-esophageal fistula in adults is rare and its diagnosis is often delayed due to the frequent lack of specific symptoms. Although there is no standard protocol, the most widely used treatment is thoracotomy with identification and dissection of the fistula tract followed by repair of bronchial and esophageal defects. CONCLUSIONS: Video-assisted thoracoscopic surgery appears to be an effective and minimally invasive approach for the treatment of broncho-esophageal fistulas, especially in young, healthy subjects. PMID- 27689524 TI - Primary umbilical endometriosis: A painful swelling in the umbilicus concomitantly with menstruation. AB - BACKGROUND: Primary umblikal endometriosis is a rare illness. In this report we aimed to discuss the management of this rare condition. CASE SUMMARY: A 28-year old nulliparous woman was present at our clinic who was suffering from painful swelling in the umbilicus during her menstruation for the last 3 months. Her examination showed a dark-color sensitive nodule of 20*15mm in size in the umbilicus. A lower abdominal tomography was performed to exclude the presence of a concomitant pelvic endometriosis, and it showed increased density consistent with subcutaneous inflammation in the umbilicus. Her medical history and physical examination suggested primary umbilical endometriosis. A total resection including umbilicus was performed. DISCUSSION: Primary umbilical endometriosis is a rare benign disease and clinically difficult to differentiate from other diseases that cause umbilical nodule. Imaging modalities have no pathognomonic findings for diagnosis. Surgical exploration and excision are the definitive and safe treatment of primary umbilical endometriosis. CONCLUSION: Total umbilical resection should be preferred to avoid local recurrent. PMID- 27689525 TI - Nonfunctional paraganglioma of the head of the pancreas: A rare case report. AB - BACKGROUND: Paragangliomas are rare neoplasms that originate from the neural crest. They are malignant in approximately 10% of cases, with a 50% survival rate at 5 years from diagnosis. In most cases, manifestations of malignancy (such as metastasis) are lacking, and paragangliomas are considered benign lesions. Pancreatic paragangliomas are extremely rare, with only 31 cases described in the scientific literature to date. CASE SUMMARY: Here we describe a case of a 55-year old Caucasian male patient referred to our institution in September 2013 for lumbar pain lasting five months. The ultrasound and the CT scan revealed a 2.5cm solid nodule located in the uncinate process of the pancreas. On the basis of this evidence, the preoperative diagnosis was a pancreatic neuroendocrine tumor (NET), which was further confirmed by a subsequent In-Pentetreotide Scan examination. A pylorus-preserving duodenocephalopancreasectomy was performed. Pancreatic paraganglioma was the final pathological diagnosis. Rare localizations of paraganglioma are often discovered casually, during imaging examinations for other clinical reasons, as happened in the case of our patient. It appears evident that the preoperative diagnosis of pancreatic paragangliomas is extremely challenging. Surgery represents the cornerstone of the clinical management of these neoplasms, primarily for the need of a definitive diagnosis, which is difficult to assess preoperatively in most cases. CONCLUSIONS: Our strategy is the same as that adopted for the management of pancreatic NETs; the dimensional limit for a conservative resection is 2cm, while major resections (Whipple's approach or distal pancreatectomy) should be employed in larger tumors, which are generally associated with a worse prognosis. PMID- 27689526 TI - Perivascular epithelioid cell tumor of the uterus: Report of two cases and mini review of the literature. AB - INTRODUCTION: Perivascular Epithelioid Cell tumor (PEComa) is a rare neoplasm of mesenchymal origin, with the uterus being the most common site of appearance, regarding the female genital tract. CASE REPORT: We present two cases of PEComas of the uterus in patients aged 57 and 42-years-old, presented to our department with palpable abdominal masses and abnormal vaginal bleeding. During follow up period, both patients are free of recurrent disease one and two years after surgery, respectively, without receiving any adjuvant treatment. CONCLUSIONS: PEComa of the female gynecological tract is a rare entity presenting with variable symptoms and different prognosis for each individual case. The diagnosis is based on histopathology and immunohistochemistry reports and the optimal treatment is the surgical resection of the tumor. PMID- 27689527 TI - Successful laparoscopic cholecystectomy for acute cholecystitis with kyphoscoliosis by the devised placement of trocar ports: A case report. AB - INTRODUCTION: Kyphoscoliosis, which is a deformity of the spine caused by aging and osteoporosis, results in various surgical difficulties for laparoscopic cholecystectomy (LC) due to low-lying costal arches, such as a small abdominal working space, disturbance of the surgical view and decreased controllability of the surgical instrument. PRESENTATION OF CASE: We herein report the case of a 92 year old woman with severe kyphoscoliosis who was diagnosed with Grade II acute cholecystitis. Taking her general status into consideration, emergency percutaneous transhepatic gallbladder drainage (PTGBD) was initially performed. After PTGBD, the patient's physical status and systemic inflammation markedly improved. She then underwent interval LC. The surgical view of the upper abdomen including the gallbladder was entirely interrupted by bilateral low-lying costal arches with adhesion to the greater omentum. To access the gallbladder without interruption by the low-lying costal arch, the first umbilical port was changed to a multi-port with surgical glove and an additional port was added in the left abdomen. Consequently, LC was safely accomplished with the creation of the critical view. DISCUSSION: A low-lying costal arch due to kyphoscoliosis can prevent surgeons from accessing the gallbladder. LC with the standard 4-port method could not be accomplished because of insufficient lifting of the low-lying costal arch. Devised placement of the ports is needed to access the gallbladder between bilateral low-lying costal arches. CONCLUSION: A transumbilical multi port and left abdominal port may be effective for successful LC of acute cholecystitis with kyphoscoliosis.

A phase sensitive, multiplicity edited long range HSQC with absorptive line shapes. AB - ME-CAGEBIRDr,X-CPMG-HSMBC pulse sequence is a phase sensitive, carbon multiplicity edited 2D-experiment for detecting heteronuclear correlations originating from long-range 1H, 13C-couplings, nJCH. The presented method allows measurement of nJCH-values as well as is capable of separating different carbon types in subspectra (13C/13CH2 and 13CH/13CH3) with minimal amount of cross talk i.e. cross peaks from wrong carbon multiplicity. Pure lineshapes and clean subspectra are achieved by utilizing CPMG in polarization transfer period, CRISIS approach in multiplicity editing period and zero-quantum filtration. The obtained spectral properties together with simple setup of the experiment make ME CAGEBIRDr,X-CPMG-HSMBC a useful addition into synthetic organic chemistry oriented NMR-tool collection. PMID- 27689531 TI - Reaction monitoring using hyperpolarized NMR with scaling of heteronuclear couplings by optimal tracking. AB - Off-resonance decoupling using the method of Scaling of Heteronuclear Couplings by Optimal Tracking (SHOT) enables determination of heteronuclear correlations of chemical shifts in single scan NMR spectra. Through modulation of J-coupling evolution by shaped radio frequency pulses, off resonance decoupling using SHOT pulses causes a user-defined dependence of the observed J-splitting, such as the splitting of 13C peaks, on the chemical shift offset of coupled nuclei, such as 1H. Because a decoupling experiment requires only a single scan, this method is suitable for characterizing on-going chemical reactions using hyperpolarization by dissolution dynamic nuclear polarization (D-DNP). We demonstrate the calculation of [13C, 1H] chemical shift correlations of the carbanionic active sites from hyperpolarized styrene polymerized using sodium naphthalene as an initiator. While off resonance decoupling by SHOT pulses does not enhance the resolution in the same way as a 2D NMR spectrum would, the ability to obtain the correlations in single scans makes this method ideal for determination of chemical shifts in on-going reactions on the second time scale. In addition, we present a novel SHOT pulse that allows to scale J-splittings 50% larger than the respective J-coupling constant. This feature can be used to enhance the resolution of the indirectly detected chemical shift and reduce peak overlap, as demonstrated in a model reaction between p-anisaldehyde and isobutylamine. For both pulses, the accuracy is evaluated under changing signal-to-noise ratios (SNR) of the peaks from reactants and reaction products, with an overall standard deviation of chemical shift differences compared to reference spectra of 0.02ppm when measured on a 400MHz NMR spectrometer. Notably, the appearance of decoupling side-bands, which scale with peak intensity, appears to be of secondary importance. PMID- 27689529 TI - Global gene profiling of aging lungs in Atp8b1 mutant mice. AB - OBJECTIVE: Recent studies implicate cardiolipin oxidation in several age-related diseases. Atp8b1 encoding Type 4 P-type ATPases is a cardiolipin transporter. Mutation in Atp8b1 gene or inflammation of the lungs impairs the capacity of Atp8b1 to clear cardiolipin from lung fluid. However, the link between Atp8b1 mutation and age-related gene alteration is unknown. Therefore, we investigated how Atp8b1 mutation alters age-related genes. METHODS: We performed Affymetrix gene profiling of lungs isolated from young (7-9 wks, n=6) and aged (14 months, 14 M, n=6) C57BL/6 and Atp8b1 mutant mice. In addition, Ingenuity Pathway Analysis (IPA) was performed. Differentially expressed genes were validated by quantitative real-time PCR (qRT-PCR). RESULTS: Global transcriptome analysis revealed 532 differentially expressed genes in Atp8b1 lungs, 157 differentially expressed genes in C57BL/6 lungs, and 37 overlapping genes. IPA of age-related genes in Atp8b1 lungs showed enrichment of Xenobiotic metabolism and Nrf2 mediated signaling pathways. The increase in Adamts2 and Mmp13 transcripts in aged Atp8b1 lungs was validated by qRT-PCR. Similarly, the decrease in Col1a1 and increase in Cxcr6 transcripts was confirmed in both Atp8b1 mutant and C57BL/6 lungs. CONCLUSION: Based on transcriptome profiling, our study indicates that Atp8b1 mutant mice may be susceptible to age-related lung diseases. PMID- 27689532 TI - Low-power suppression of fast-motion spin 3/2 signals. AB - Triple Quantum Filters (TQFs) are frequently used for the selection of bi exponentially relaxing spin 3/2 nuclei (in particular 23Na) in ordered environments, such as biological tissues. These methods provide an excellent selection of slow-motion spins, but their sensitivity is generally low, and coherence selection requirements may lead to long experiments when applied in vivo. Alternative methods, such as 2P DIM, have demonstrated that the sensitivities of the signals from bi-exponentially relaxing sodium can be significantly increased using strategies other than TQFs. A shortcoming of the 2P DIM method is its strong dependence on B0 inhomogeneities. We describe here a method, which is sensitive to the slow-motion regime, while the signal from spins in the fast-motion regime is suppressed. This method is shown to be more effective than TQFs, requires minimal phase cycling for the suppression of the influence of rf inhomogeneity, and has less dependence on resonance offsets and B0-inhomogeneity than 2P DIM. PMID- 27689534 TI - Is N-acetylcysteine effective in the treatment of pulmonary fibrosis? AB - Idiopathic pulmonary fibrosis is a progressive chronic respiratory disease that in final stages carries high mortality. Several treatment options have been proposed, including N-acetylcysteine, but its role is not clearly established. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified eight systematic reviews including 16 trials addressing the question of this article. We combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded N acetylcysteine might increase the risk of hospitalizations and exacerbations. While it is unclear whether this leads to increased mortality because the certainty of the evidence is very low, in general there is consensus that it should not be used except in the context of a new clinical trial. PMID- 27689535 TI - Versatile and Resilient Hydrogen-Bonded Host Frameworks. AB - Low-density molecular host frameworks, whether equipped with persistent molecular scale pores or virtual pores that are sustainable only when occupied by guest molecules, have emerged as a promising class of materials owing to the ability to tailor the size, geometry, and chemical character of their free space through the versatility of organic synthesis. As such, molecular frameworks are promising candidates for storage, separations of commodity and fine chemicals, heterogeneous catalysis, and optical and electronic materials. Frameworks assembled through hydrogen bonds, though generally not stable toward collapse in the absence of guests, promise significant chemical and structural diversity, with pores that can be tailored for a wide range of guest molecules. The utility of these frameworks, however, depends on the resilience of n-dimensional hydrogen bonded motifs that serve as reliable building blocks so that the molecular constituents can be manipulated without disruption of the anticipated global solid-state architecture. Though many hydrogen-bonded frameworks have been reported, few exist that are amenable to systematic modification, thus limiting the design of functional materials. This Account reviews discoveries in our laboratory during the past decade related to a series of host frameworks based on guanidinium cations and interchangeable organosulfonate anions, in which the 3 fold symmetry and hydrogen-bonding complementarity of these ions prompt the formation of a two-dimensional (2-D) quasi-hexagonal hydrogen-bonding network that has proven to be remarkably resilient toward the introduction of a wide range of organic pendant groups attached to the sulfonate. Since an earlier report in this journal that focused primarily on organodisulfonate host frameworks with lamellar architectures, this unusually persistent network has afforded an unparalleled range of framework architectures and hundreds of new crystalline materials with predictable solid-state architectures. These range from the surprising discovery of inclusion compounds in organomonosulfonates (GMS), as well as organodisulfonates (GDS), structural isomerism reminiscent of microstructures observed in soft matter, a retrosynthetic approach to the synthesis of polar crystals, separation of molecular isomers, storage of unstable molecules, formation of a zeolite-like hydrogen-bonded framework, and postsynthetic pathways to inclusion compounds through reversible guest swapping in flexible GS frameworks. Collectively, the examples described in this Account illustrate the potential for hydrogen-bonded frameworks in the design of molecular materials, the prediction of solid-state architecture from simple empirical parameters, and the importance of design principles based on robust high dimensional networks. These and other emerging hydrogen-bonded frameworks promise new advanced materials that capitalize fully on the ability of materials chemists to manipulate solid-state structure through molecular design. PMID- 27689533 TI - Iodinated benzimidazole PARP radiotracer for evaluating PARP1/2 expression in vitro and in vivo. AB - BACKGROUND: PARP inhibitors (PARPi) have the potential to impact cancer therapy in a selective patient population; however, despite current patient selection methods clinical trials have shown mixed response rates. It is therefore clinically useful to determine which patients will respond prior to receiving PARPi therapy. One essential biomarker is to measure the level of PARP enzyme expression in tumors. Small molecule radiotracers have been developed to accurately quantify PARP-1 expression in vitro and in vivo. [125I]KX-02-019 is the first report of a radioiodinated analogue of the benzimidazole class of PARPi. Herein, we studied the pharmacological properties of [125I]KX-02-019 as well as the in vivo biodistribution. METHODS: [125I]KX-02-019 was evaluated in both cancer and non-cancer cell lines. We evaluated the pharmacologic properties of [125I]KX-02-019 in live cells by measuring enzyme association and dissociation kinetics, saturation, and specificity. In addition, competitive inhibition experiments were carried out with commercially available PARPi. Protein expression was analyzed by Western blot to compare PARP-1 and PARP-2 expression across cell lines studied. The biodistribution was studied in a mouse EMT6 tumor model at time points of 0.5, 1, 2, 4 and 6h. RESULTS: [125I]KX-02-019 showed subtle differences in pharmacological properties in the absence of PARP-2. In addition, [125I]KX-02-019 was competitively displaced by clinical PARPi. In vivo biodistribution studies showed an increasing tumor to muscle ratio over 6h as well as fast clearance from healthy tissues. CONCLUSION: [125I]KX-02-019 has binding sites in both PARP1 KO cells as well as PARP2 KO cells showing higher affinity for PARP-2. This observation is supported by a decrease in binding affinity in PARP2 KO cells compared to PARP1 KO cells. The pharmacologic and biological properties of [125I]KX-02-019 studied in vitro and in vivo showed that this analogue may be useful in determining pharmacokinetic and pharmacodynamic properties of clinical PARPi. PMID- 27689536 TI - Charge-Carrier Dynamics in 2D Hybrid Metal-Halide Perovskites. AB - Hybrid metal-halide perovskites are promising new materials for use in solar cells; however, their chemical stability in the presence of moisture remains a significant drawback. Quasi two-dimensional (2D) perovskites that incorporate hydrophobic organic interlayers offer improved resistance to degradation by moisture, currently still at the cost of overall cell efficiency. To elucidate the factors affecting the optoelectronic properties of these materials, we have investigated the charge transport properties and crystallographic orientation of mixed methylammonium (MA)-phenylethylammonium (PEA) lead iodide thin films as a function of the MA-to-PEA ratio and, thus, the thickness of the "encapsulated" MA lead-halide layers. We find that monomolecular charge-carrier recombination rates first decrease with increasing PEA fraction, most likely as a result of trap passivation, but then increase significantly as excitonic effects begin to dominate for thin confined layers. Bimolecular and Auger recombination rate constants are found to be sensitive to changes in electronic confinement, which alters the density of states for electronic transitions. We demonstrate that effective charge-carrier mobilities remain remarkably high (near 10 cm2V-1s-1) for intermediate PEA content and are enhanced for preferential orientation of the conducting lead iodide layers along the probing electric field. The trade-off between trap reduction, electronic confinement, and layer orientation leads to calculated charge-carrier diffusion lengths reaching a maximum of 2.5 MUm for intermediate PEA content (50%). PMID- 27689537 TI - Enhancement of Energy Storage and Photoresponse Properties of Folic Acid Polyaniline Hybrid Hydrogel by in Situ Growth of Ag Nanoparticles. AB - Electrically conductive hydrogels are a fascinating class of materials that exhibit multifarious applications such as photoresponse, energy storage, etc., and the three-dimensional micro- and nanofibrillar structures of the gels are the key to those applications. Herein, we have synthesized a hybrid hydrogel based on folic acid (F) and polyaniline (PANI) in which F acts as a supramolecular cross linker of PANI chains. The gels are mechanically robust and are characterized by field-emission scanning electron microscopy, transmission electron microscopy, and spectroscopic, rheological, and universal testing measurements. The hybrid xerogel exhibit a BET surface area 238 m2 g-1, conductivity of 0.04 S/cm, specific capacitance of 295 F/g at a current density of 1A/g, and photocurrent of ~2 mA under white-light illumination. Silver nanoparticles (AgNPs) are in situ grown to elegantly improve the conductivity, energy storage, and photoresponse capability of the gels. The formation of AgNPs drastically improves the specific capacitances up to 646 F/g (at current density 1A/g), excellent rate capability (403 F/g at 20 A/g), and stable cycling performance with a retention ratio of 74% after 5000 cycles. The AgNPs embedded gel exhibits dramatic enhancement of photocurrent to 56 mA, and its time-dependent photoillumination corroborates faster rise and decay of current compared to those of folic acid-polyaniline hydrogel. PMID- 27689538 TI - DPPTE Thiolipid Self-Assembled Monolayer: A Critical Assay. AB - Supported lipid membranes represent an elegant way to design a fluid interface able to mimic the physicochemical properties of biological membranes, with potential biotechnological applications. In this work, a diacyl phospholipid, the 1,2-dipalmitoyl-sn-glycero-3-phosphothioethanol (DPPTE), functionalized with a thiol group, was immobilized on a gold surface. In this molecule, the thiol group, responsible for the Au-S bond (45 kJ/mol) is located on the phospholipid polar head, letting the hydrophobic chain protrude from the film. This system is widely used in the literature but is no less challenging, since its characterization is not complete, as several discordant data have been obtained. In this work, the film was characterized by cyclic voltammetry blocking experiments, to verify the SAM formation, and by reductive desorption measurements, to estimate the molecular density of DPPTE on the gold surface. This value has been compared to that obtained by quartz crystal microbalance measurements. Ellipsometry and impedance spectroscopy measurements have been performed to obtain information about the monolayer thickness and capacitance. The film morphology was investigated by atomic force microscopy. Finally, Monte Carlo simulations were carried out, in order to gain molecular information about the morphologies of the DPPTE SAM and compare them to the experimental results. We demonstrate that DPPTE molecules, incubated 18 h below the phase transition temperature (T = 41.1 +/- 0.4 degrees C) in ethanol solution, are able to form a self-assembled monolayer on the gold surface, with domain structures of different order, which have never been reported before. Our results make possible rationalization of the scattered results so far obtained on this system, giving a new insight into the formation of phospholipids SAMs on a gold surface. PMID- 27689539 TI - DFT Study of Hydrogen-Bonding Interaction, Solvation Effect, and Electric-Field Effect on Raman Spectra of Hydrated Proton. AB - Strong hydrogen-bonding interaction and Raman spectra of hydrated proton have been investigated using hybrid density functional theory method B3LYP. The solvation model of density (SMD) approach is employed in the present calculation to simulate hydrated protons in aqueous solution. Focusing on the different hydrogen-bonded Eigen-water and Zundel-water interactions, we present a better assignment of Raman signals of hydrated proton on the basis of vibrational analysis in different environments. Our results showed that B3LYP calculations could give a good prediction for characteristic vibrational frequencies of Eigen and Zundel isomers in liquid phase. The O-H stretching vibrational frequencies from Eigen and Zundel units are very sensitive to hydrogen-bonding interaction with solvent water molecules. Moreover, the solvation effect and the external electric-field effect lead to the proton deviating from the central position of Zundel structure and finally resulting in a transition to Eigen one in aqueous solution. Furthermore, by combining theoretical prediction and Raman scattering theory, we calculate absolute Raman intensities of characteristic signals based on the polarizability tensor derivatives of hydrated proton clusters. This is very helpful to infer the microstructure of hydrated protons in aqueous solution by using Raman measurements.

AB - Studies of the complexation of new promising ligands with uranyl (UO22+) and other seawater cations can aid the development of more efficient, selective, and robust sorbents for the recovery of uranium from seawater. In this work, we propose that the ligand design principles based on structural preorganization can be successfully applied to obtain a dramatic enhancement in UO22+ ion binding affinity and selectivity. This concept is exemplified through the investigation of the complexes of UO22+, VO2+, and VO2+ with the highly preorganized ligand 1,10-phenanthroline-2,9-dicarboxylic acid (PDA) using a combination of fluorescence and absorbance techniques, along with density functional theory (DFT) calculations. The measured stability constant value, log K1, of 16.5 for the UO22+/PDA complex is very high compared to uranyl complexes with other dicarboxylic ligands. Moreover, PDA exhibits strong selectivity for uranyl over vanadium ions, since the determined stability constant values of the PDA complexes of the vanadium ions are quite low (V(IV) log K1 = 7.4, V(V) = 7.3). The structures of the corresponding UO22+, VO2+, and VO2+ complexes with PDA were identified by systematic DFT calculations and helped to interpret the stronger binding affinity for uranium over the vanadium ions. Because of its high chemical stability, selectivity, and structural preorganization for UO22+ complexation, PDA is a very promising candidate that can be potentially used in the development of novel adsorbent materials for the selective extraction of uranium from seawater.

AB - Olefin metathesis reactions with 3E-1,3-dienes using Z-selective cyclometalated ruthenium benzylidene catalysts are described. In particular, a procedure for employing 3E-1,3-dienes in Z-selective homodimerization and cross-metathesis with terminal alkenes is detailed. The reaction takes advantage of the pronounced chemoselectivity of a recently reported ruthenium-based catalyst containing a cyclometalated NHC ligand for terminal alkenes in the presence of internal E alkenes. A wide array of commonly encountered functional groups can be tolerated, and only a small excess (1.5 equiv) of the diene coupling partner is required to achieve high yields of the desired internal E,Z-diene cross-metathesis product. Computational studies have been performed to elucidate the reaction mechanism. The computations are consistent with a diene-first pathway. The reaction can be used to quickly assemble structurally complex targets. The power of this cross metathesis reaction is demonstrated by the concise syntheses of two insect pheromones.

In addition, substituents on the aryl halide portion of the ortho-phenol arylation substrates significantly influenced the formation of an oxidized side product. PMID- 27689543 TI - Experimental and theoretical analysis of organic dyes having a double D-pi-A configurations for dye-sensitized solar cells. AB - Two spiro-like organic dyes linked at the thiophene bridge (KS-11 and KS-12) together with the original rod-shaped D-pi-A configuration (C1) were designed, synthesized, and characterized based on their electronic structure, and determine the photophysical and photovoltaic properties for its application in dye sensitized solar cells. Compared to C1, the double D-pi-A spiro-like configuration, which consists of two separated light-harvesting moieties, was found to be beneficial to photocurrent generation provided that they are separated properly to prevent intramolecular exciton annihilation. This was observed when KS-11, which is linked at the beta-position of the thiophene moiety of D-pi-A, was compared with KS-12, where the two D-pi-A are linked with an additional thiophene using a alpha-beta linkage. The results show that KS-12 produced a 20% and 17% increase in photovoltaic efficiency under simulated AM 1.5G solar irradiation compared to KS-11 and C1, respectively. This increase in photovoltaic performance is credited mostly to the reduction of recombination effects and the increase in the density of states at the semiconductor surface due to high dye loading and better charge-transfer properties. PMID- 27689542 TI - Safe Routes to Play? Pedestrian and Bicyclist Crashes Near Parks in Los Angeles. AB - BACKGROUND: Areas near parks may present active travelers with higher risks than in other areas due to the confluence of more pedestrians and bicyclists, younger travelers, and the potential for increased traffic volumes. These risks may be amplified in low-income and minority neighborhoods due to generally higher rates of active travel or lack of safety infrastructure. This paper examines active travel crashes near parks and builds on existing research around disparities in park access and extends research from the Safe Routes to School and Safe Routes to Transit movements to parks. METHODS: We utilized the Green Visions Parks coverage, encompassing Los Angeles County and several other cities in the LA Metropolitan area. We used negative bionomial regression modeling techniques and ten years of geolocated pedestrian and bicyclist crash data to assess the number of active travel injuries within a quarter mile (~400m) buffer around parks. We controlled for differential exposures to active travel using travel survey data and Bayesian smoothing models. RESULTS: Of 1,311,736 parties involved in 608,530 crashes, there were 896,359 injuries and 7317 fatalities. The number of active travel crash injuries is higher within a quarter-mile of a park, with a ratio of 1.52 per 100,000 residents, compared to areas outside that buffer. This higher rate near parks is amplified in neighborhoods with high proportions of minority and low-income residents. Higher traffic levels are highly predictive of active travel crash injuries. CONCLUSIONS: Planners should consider the higher risks of active travel near parks and the socioeconomic modification of these risks. Additional traffic calming and safety infrastructure may be needed to provide safe routes to parks. PMID- 27689545 TI - Effect of Chlorine Substitution in Modulating the Relative Importance of Two Intermolecular Interactions: The Microwave Spectrum and Molecular Structure of (E)-1-Chloro-2-fluoroethylene-HCl. AB - Fourier transform microwave rotational spectroscopy is used to determine the structure of the gas-phase bimolecular complex formed between (E)-1-chloro-2 fluoroethylene and hydrogen chloride. Extensively split by nuclear quadrupole hyperfine structure and isotopic dilution, the spectrum is first identified via weak features observed using a broadband chirped pulse spectrometer in the 5.6 18.1 GHz range and studied in detail with greater sensitivity and resolution over 6.0-20.0 GHz with a Balle-Flygare, narrowband instrument. The complex has a geometry similar to that of vinyl fluoride-HCl, with HCl binding across the C?C double bond, forming a hydrogen bond to the fluorine atom of the haloethylene and bending to allow a secondary interaction to develop with the hydrogen atom in the cis position. Further consideration of structural details among the complexes of hydrogen fluoride and hydrogen chloride with (E)-1-chloro-2-fluoroethylene and vinyl fluoride suggests that the addition of a trans Cl atom in vinyl fluoride enhances the significance of the secondary interaction while deemphasizing that of the hydrogen bond.

PMID- 27689547 TI - Steroid/Antiviral for the treatment of Bell's palsy: Double blind randomized clinical trial. AB - BACKGROUND: A large number of patients with Bell's palsy fail to recover facial function completely after steroid therapy. Only a few small trials have been conducted to test whether outcomes can be improved by the addition of antiviral therapy. OBJECTIVE: To evaluate the efficacy of treatment with steroid alone versus steroid + antiviral in a group of patients with moderately severe to severe acute Bell's palsy. METHODS: Fifty eligible patients out of a total of 65 with acute onset Bell's palsy were randomized to receive the two treatments. Evaluation was performed before starting treatment, after 2 weeks of treatment and 3 months after onset, using the House and Brackmann facial nerve grading system (HB) and the Sunnybrook grading system.This study was registered with ClinicalTrials.gov, number NCT02328079. RESULTS: Both treatments had comparable demographics and clinical scores at baseline. There was greater improvement in the mean HB and Sunnybrook scores of the steroid + antiviral group in comparison to steroid group at 3 months. At the end of the 3rd month, 17 patients (68%) had good recovery and 8 patients (32%) had poor recovery in the steroid group compared with 23 patients (92%) and 2 (8%) respectively in the steroid and antiviral group (p = 0.034). CONCLUSION: The combination of steroid and antiviral treatment increases the possibility of recovery in moderately severe to complete acute Bell's palsy. PMID- 27689548 TI - Mental chronometry and mental rotation abilities in stroke patients with different degrees of sensory deficit. AB - BACKGROUND: Motor imagery is used for treatment of motor deficits after stroke. Clinical observations suggested that motor imagery abilities might be reduced in patients with severe sensory deficits. This study investigated the influence of somatosensory deficits on temporal (mental chronometry, MC) and spatial aspects of motor imagery abilities. METHODS: Stroke patients (n = 70; <6 months after stroke) were subdivided into 3 groups according to their somatosensory functions. Group 1 (n = 31) had no sensory deficits, group 2 (n = 27) had a mild to moderate sensory impairment and group 3 (n = 12) had severe sensory deficits. Patients and a healthy age-matched control group (n = 23) participated in a mental chronometry task (Box and Block Test, BBT) and a mental rotation task (Hand Identification Test, HIT). MC abilities were expressed as a ratio (motor execution time-motor imagery time/motor execution time). RESULTS: MC for the affected hand was significantly impaired in group 3 in comparison to stroke patients of group 1 (p = 0.006), group 2 (p = 0.005) and healthy controls (p < 0.001). For the non affected hand MC was similar across all groups. Stroke patients had a slower BBT motor execution than healthy controls (p < 0.001), and group 1 executed the task faster than group 3 (p = 0.002). The percentage of correct responses in the HIT was similar for all groups. CONCLUSION: Severe sensory deficits impair mental chronometry abilities but have no impact on mental rotation abilities. Future studies should explore whether the presence of severe sensory deficits in stroke patients reduces the benefit from motor imagery therapy. PMID- 27689549 TI - The effects of combined repetitive transcranial magnetic stimulation and transcranial direct current stimulation on motor function in patients with stroke. AB - BACKGROUND: Both transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), when provided to stroke patients in combination with motor training, enhance therapeutic efficacy and motor function. However, the majority of previous studies have only examined a single treatment modality. OBJECTIVE: The authors investigated the modulating influence of combination dual mode brain stimulation upon bihemispheric stimulation with motor training in stroke patients. METHODS: Twenty stroke patients with hemiparesis underwent five randomly arranged sessions of diverse combinations of rTMS and tDCS. We applied cathodal or anodal tDCS over the contralesional primary motor cortex (cM1) and 10 Hz rTMS over the ipsilesional primary motor cortex (iM1) in a simultaneous or preconditioning method including sham stimulation. Immediately after dual-mode stimulation, sequential hand motor training was performed for 5 minutes. The total pulses of rTMS and the duration of tDCS and motor training were the same for all sessions. Cortical excitability and sequential motor performance were evaluated before and after each session. RESULTS: Motor function and corticomotor excitability following simultaneous stimulation via cathodal tDCS over the cM1 combined with 10 Hz rTMS over the iM1 were significantly increased after the intervention, with significantly greater motor improvement than seen with other treatment conditions (P < 0.05). CONCLUSION: For the combination of bihemispheric rTMS and tDCS, simultaneous stimulation of cathodal tDCS and 10 Hz rTMS results in better motor performance in stroke patients than other combination methods. This result seemed to be related to effective modulation of interhemispheric imbalance of cortical excitability by dual-mode stimulation. PMID- 27689550 TI - Association between genetic variation in the dopamine system and motor recovery after stroke. AB - BACKGROUND: The dopamine system plays a key role in motor learning and neuroplasticity. Several studies have studied the efficacy of dopaminergic drugs in enhancing motor recovery after stroke, but the effects are controversial. Although genetic variations in plasticity-related genes influence each individual's capacity for recovery after stroke, limited studies have investigated the effects of polymorphism of dopamine-related genes. OBJECTIVE: We aimed to investigate the association between motor recovery in stroke patients and polymorphisms in the dopamine-related genes catechol-O-methyltransferase (COMT), dopamine receptor D1 (DRD1), DRD2, and DRD3. METHODS: We enrolled 74 patients with first-ever stroke (42 males, 32 females, mean age: 61.4+/-14.1 y). During admission, blood samples were collected, and the genotypes of COMT, DRD1, DRD2, and DRD3 were analyzed. The primary outcome was assessed with Fugl-Meyer Assessment (FMA) at 1 week, 3 months, and 6 months after stroke; secondary outcomes were assessed with Functional Independence Measure (FIM) and mini-mental state examination at 3 and 6 months after stroke. The association between polymorphisms and functional outcome was analyzed. RESULTS: There were no significant associations between COMT polymorphisms and FMA or FIM scores at 1 week after stroke or between DRD1, DRD2, or DRD3 genotypes and FMA or FIM scores at any point. COMT genotypes were significantly associated with FMA and FIM at 3 months (p < 0.01 and p < 0.05, respectively) and at 6 months (p < 0.01 and p < 0.05, respectively). CONCLUSION: These data suggest that genetic variation of dopamine-related genes may affect motor recovery after stroke and that COMT polymorphism could be useful for predicting motor recovery. PMID- 27689551 TI - Effects of anodal tDCS and occupational therapy on fine motor skill deficits in patients with chronic stroke. AB - BACKGROUND: A growing body of evidence supports the effectiveness of using transcranial direct current stimulation (tDCS) in patients with chronic hand motor impairment resulting from stroke. OBJECTIVE: In this study, we investigate and compare the combined effects of anodal tDCS and occupational therapy (OT) to sham stimulation with OT (control) on fine motor skill deficits of chronic stroke patients. METHODS: A total of 26 stroke patients (at >= 9 months) were randomly assigned to an active treatment or a control group in a double-blinded, sham controlled, parallel design study. Each group received OT for 45 min/day (10 sessions for 2 weeks). Treatment was preceded by either 20 minutes of 2 mA anodal tDCS over ipsilesional M1 or sham tDCS. A modified Jebsen-Taylor Hand Function Test (mJTHFT) was administered as primary outcome measure, and handgrip dynamometer and upper limb Fugl-Meyer (ULFM) assessments were performed as secondary outcomes. The assessment was done at baseline (T0), after the interventions on day 1(T1), day 10 (T2) and day 40 (T3). RESULTS: We observed a statistically significant effect in the tDCS group when the results were compared to the sham group. The mJTHFT times were significantly shorter immediately after treatment and at day 40. The intervention had no effect on handgrip strength or ULFM score. CONCLUSION: Fine motor skill deficits in chronic stroke survivors can be improved when intensive OT is primed with anodal tDCS over the ipsilesional hemisphere.

AB - Education Management Information System (EMIS) is a widely acceptable and developing technology within the Information Technology field. The advancement in technology in this century is being collaborated with scientific invention or explorer and information strengthening or development. This paper presents the results and experiences gained from applying students oriented EMIS for monitoring and managing mental health. The Mental Health of students depends on the acquiring adequate knowledge on basic concepts within a time period or academic schedule. It's obviously significance to evaluate and appraise the stress stimulators as a challenge or threat. The theoretical framework for the study was designed for analyzing the stress stimulators, academic performance and EMIS accessibility. The sample examined in this study was stratified random sample from 75 students specifically all engineering college in Dindigul District of Tamilnadu. The primary factor is the academic stress stimulators that form one module of EMIS for each of the key variable such as curriculum & instruction related stressors, placement related, teamwork related and assessment related. The Mental Health related stress stimulators namely curriculum & syllabus, placement related, assessment related and team work related have a significant influence on academic performance by students in various institution. The important factor leading to the EMIS application in monitoring stress stimulators is curriculum & syllabus related and assessment related. PMID- 27689553 TI - Personalized reminiscence therapy M-health application for patients living with dementia: Innovating using open source code repository. AB - Dementia is known to be an illness which brings forth marked disability amongst the elderly individuals. At times, patients living with dementia do also experience non-cognitive symptoms, and these symptoms include that of hallucinations, delusional beliefs as well as emotional liability, sexualized behaviours and aggression. According to the National Institute of Clinical Excellence (NICE) guidelines, non-pharmacological techniques are typically the first-line option prior to the consideration of adjuvant pharmacological options. Reminiscence and music therapy are thus viable options. Lazar et al. [3] previously performed a systematic review with regards to the utilization of technology to delivery reminiscence based therapy to individuals who are living with dementia and has highlighted that technology does have benefits in the delivery of reminiscence therapy. However, to date, there has been a paucity of M health innovations in this area. In addition, most of the current innovations are not personalized for each of the person living with Dementia. Prior research has highlighted the utility for open source repository in bioinformatics study. The authors hoped to explain how they managed to tap upon and make use of open source repository in the development of a personalized M-health reminiscence therapy innovation for patients living with dementia. The availability of open source code repository has changed the way healthcare professionals and developers develop smartphone applications today. Conventionally, a long iterative process is needed in the development of native application, mainly because of the need for native programming and coding, especially so if the application needs to have interactive features or features that could be personalized. Such repository enables the rapid and cost effective development of application. Moreover, developers are also able to further innovate, as less time is spend in the iterative process. PMID- 27689554 TI - Modeling the virus-immune system interactions in the peripheral bloodstream of HIV infected individuals using a cellular automata model with considering the effects of antiretroviral therapy. AB - BACKGROUND: According to the World Health Organization, by the end of last year, about 37 million people throughout the world were diagnosed with AIDS and millions of people die each year from this disease. OBJECTIVE: To develop an appropriate model which depicts the mechanism of the dynamics involved in the interactions between HIV and immune system in peripheral bloodstream of HIV infected individuals by considering the phenomena of virus mutation and taking into account the role of latently infected cells in speared of infection and considering the effects of antiretroviral drugs and occurrence of drug resistance in our model in order to assess the results obtained from applying different therapeutic methods. METHODS: Two-dimensional CA model with Moor neighboring was developed. Various agents which they were referring to peripheral bloodstream particles of HIV infected individuals were defined. Then the biological rules were extracted from both expert knowledge and the authoritative articles. The extracted rules were applied for updating the states of these agents. The effects of using antiretroviral drug treatment were considered by applying drug's effectiveness of both of protease and reverse transcriptase inhibitors as two separate inputs of model. RESULTS: Time evolution curves of concentrations of defined agents were shown as our results. In case of considering no treatment, our results showed that concentrations of healthy CD4+T cells reached the threshold of AIDS after a bout 250 weeks. By applying monotherapy method, the concentrations of these cells remained on the threshold of AIDS for a long time and applying combined antiretroviral therapy (cART) method leaded to increase the concentration of these cells 20% upper than threshold of AIDS. Also, by applying monotherapy and cART compared with no treatment, the concentrations of infected CD4+T cells 10% and 40% decreased further, respectively and for the level of viral load, leads to a reduction of almost 55% and 90%, respectively. Belated treatment, comparison with early treatment, caused almost 10% reduce (increase) in steady state concentrations of healthy (infected) cells. PMID- 27689555 TI - Forecasting behavior in smart homes based on sleep and wake patterns. AB - BACKGROUND: The goal of this research is to use smart home technology to assist people who are recovering from injuries or coping with disabilities to live independently. OBJECTIVE: We introduce an algorithm to model and forecast wake and sleep behaviors that are exhibited by the participant. Furthermore, we propose that sleep behavior is impacted by and can be modeled from wake behavior, and vice versa. METHODS: This paper describes the Behavior Forecasting (BF) algorithm. BF consists of 1) defining numeric values that reflect sleep and wake behavior, 2) forecasting wake and sleep values from past behavior, 3) analyzing the effect of wake behavior on sleep and vice versa, and 4) improving prediction performance by using both wake and sleep scores. RESULTS: The BF method was evaluated with data collected from 20 smart homes. We found that regardless of the forecasting method utilized, wake behavior and sleep behavior can be modeled with a minimum accuracy of 84%. Additionally, normalizing the wake and sleep scores drastically improves the accuracy to 99%. CONCLUSIONS: The results show that we can effectively model wake and sleep behaviors in a smart environment. Furthermore, wake behaviors can be predicted from sleep behaviors and vice versa. PMID- 27689556 TI - Muscle synergy extraction during arm reaching movements at different speeds. AB - OBJECTIVE: Muscle synergy is the activation of a group of muscles that contribute to a particular movement. The goal of the present study is to examine the hypothesis that human reaching movements at different speeds share similar muscle synergies and to investigate the kinesiology basis and innervation of muscles. METHODS: Electromyographic activity from six muscles of the upper limb and shoulder girdle were recorded during three movements at different speeds, i.e. slow, moderate and fast. The effect of window length on the RMS signal of the EMG was analyzed and then EMG envelope signals were decomposed using non-negative matrix factorization. For each of the ten subjects, three synergies were extracted which accounted for at least 99% of the VAF. For each movement, the muscle synergies and muscle activation coefficients of all participants were clustered in to three partitions. Investigation showed a high similarity and dependency of cluster members due to the cosine similarity and mutual information in muscle synergy clustering. For further verification, the EMG envelope signals for all subjects were reconstructed. RESULTS: The results indicated a lower reconstruction error using the center of the muscle synergy clusters in comparison with the average of the activation coefficients, which confirms the current research's hypothesis. PMID- 27689557 TI - Increased rate of bacterial colonization on PE-components in total joint arthroplasty: An evaluation through sonication. AB - BACKGROUND: It is currently unclear if an isolated exchange of the mobile components, in cases of periprosthetic joint infection (PJI), leads to a complete eradication of all bacteria or if residual bacteria remain attached to the retained components? OBJECTIVE: The purpose of this study was to investigate if bacteria only adhere to certain components or materials, or if they are ubiquitously distributed throughout the joint. METHODS: Twenty hundred and eighty four patients undergoing revision total hip or total knee arthroplasty surgery were included in this retrospective cohort study. Synovial fluid cultures, periprosthetic tissue cultures, histological samples and sonicate fluid cultures (SFC) from the individual endoprosthetic components were acquired. The isolated bacterial species were recorded according to their endoprosthetic component of origin. RESULTS: In 72% of all cases with multiple SFC, the cultures were concordant with all samples being either homogenously negative or showing positive bacterial growth. The polyethylene (PE) components showed a significantly higher rate of bacterial isolation than the non-mobile components. All components and materials showed bacterial colonization, however between all other components or materials were not statistically significant. CONCLUSIONS: PE components show a higher rate of bacterial isolation than other components. If an isolated bearing exchange is performed this should be supplemented by adequate antimicrobial therapy. PMID- 27689558 TI - Recommendations for measuring non-image-forming effects of light: A practical method to apply on cognitive impaired and unaffected participants. AB - BACKGROUND: The non-image-forming effects of luminous radiation on people with intellectual disabilities or dementia received attention from researchers. Such studies, however, have generally been conducted using disparate methodologies which precludes generalization and reproducibility. OBJECTIVE: The aim of this study was to determine the practical applicability of measurement devices for studies investigating non-image-forming effects of luminous radiation, specifically for people with intellectual disabilities or dementia. METHODS: In three experiments, ten cognitive impaired people and thirty-nine unaffected subjects participated by wearing one or more portable devices. Six devices were assessed in total. Measurement data was accompanied with user experiences obtained from questionnaires, interviews and observations in order to assess the devices on practical and comfort issues. RESULTS: On average, the devices worn by the cognitive impaired subjects were not experienced as annoying or irritating. No significant differences are found between genders and for one of the portable devices significantly less annoyance was reported by the cognitive impaired participants compared to the unaffected group of participants. INNOVATIVE SOLUTION: The three phases of the research process in towards measuring personal luminous exposures are: selection of the most suitable portable device, application of the assessment method, and the application of the device in the (pilot) study. CONCLUSIONS: However, the findings of this study suggest that inaccuracies potentially caused by practical and comfort issues associated with the portable devices need to be considered. PMID- 27689559 TI - Development of a mobile application for oral cancer screening. AB - PURPOSE: To develop a mobile application (app) for oral cancer screening. METHODS: The app was developed using Android system version 4.4.2, with JAVA language. Information concerning sociodemographic data and risk factors for oral cancer development, e.g., tobacco and alcohol use, sun exposure and other contributing factors, such as unprotected oral sex, oral pain and denture use, were included. We surveyed a population at high risk for oral cancer development and then evaluated the sensitivity/specificity/accuracy and predictive values of clinical oral diagnosis between two blinded trained examiners, who used movies and data from the app, and in loco oral examination as gold-standard. RESULTS: A total of 55 individuals at high risk for oral cancer development were surveyed. Of these, 31% presented homogeneous/heterogeneous white lesions with potential of malignancy. The clinical diagnoses performed by the two examiners using videos were found to have sensitivity of 82%-100% (average 91%), specificity of 81%-100% (average 90.5%), and accuracy of 87.27%-95.54% (average 90.90%), as compared with the gold-standard. The Kappa agreement value between the gold-standard and the examiner with the best agreement was 0.597. CONCLUSION: Mobile apps including videos and data collection interfaces could be an interesting alternative in oral cancer research development.

PMID- 27689561 TI - Angiojet rheolytic thrombectomy combined with catheter fragmentation in a patient presenting with massive pulmonary embolism and cardiogenic shock. AB - Massive pulmonary embolism (MPE) is associated with a high rate of mortality, and chronic thromboembolic pulmonary hypertension leads to ongoing morbidity among many survivors. Here we report a case of a MPE successfully treated by Angiojet rheolytic thrombectomy combined with catheter fragmentation. This is the first report of the use of these two methods together for MPE treatment. PMID- 27689562 TI - Cybersecurity in healthcare: A systematic review of modern threats and trends. AB - BACKGROUND: The adoption of healthcare technology is arduous, and it requires planning and implementation time. Healthcare organizations are vulnerable to modern trends and threats because it has not kept up with threats. OBJECTIVE: The objective of this systematic review is to identify cybersecurity trends, including ransomware, and identify possible solutions by querying academic literature. METHODS: The reviewers conducted three separate searches through the CINAHL and PubMed (MEDLINE) and the Nursing and Allied Health Source via ProQuest databases. Using key words with Boolean operators, database filters, and hand screening, we identified 31 articles that met the objective of the review. RESULTS: The analysis of 31 articles showed the healthcare industry lags behind in security. Like other industries, healthcare should clearly define cybersecurity duties, establish clear procedures for upgrading software and handling a data breach, use VLANs and deauthentication and cloud-based computing, and to train their users not to open suspicious code. CONCLUSIONS: The healthcare industry is a prime target for medical information theft as it lags behind other leading industries in securing vital data. It is imperative that time and funding is invested in maintaining and ensuring the protection of healthcare technology and the confidentially of patient information from unauthorized access. PMID- 27689563 TI - Relative lower body circumferences are associated with the prevalence of metabolic syndrome and arterial stiffness. AB - Body circumference is a known health-related factor. This cross-sectional study aimed to investigate the associations of relative lower body circumferences with metabolic syndrome (MetS) and arterial stiffness (AS) in 684 men aged > 40 (mean, 54.6 +/- 8.5) years. Participants were measured for waist, thigh, and calf circumferences; underwent blood tests and blood pressure measurements to detect MetS; and received brachial ankle pulse wave velocity measurements to measure AS. The waist-to-thigh, waist-to-calf, and thigh-to-calf circumferences were calculated and classified into quartiles. Age-adjusted multiple logistic regression models were used to assess the associations between the circumference ratios and AS vs. non-AS and MetS vs. non-MetS (systolic and diastolic blood pressure, triglycerides, high-density lipoprotein cholesterol, and fasting plasma glucose). The mean body mass index was 24.9 +/- 2.8 kg/m2; the mean waist, thigh, and calf circumferences were 87.4 +/- 7.6, 53.8 +/- 4.2, and 36.4 +/- 2.7 cm, respectively. Compared to the lowest quartiles, participants in waist-to-thigh circumference quartiles 3 (odds ratio [OR] = 3.195, 95% confidence interval [CI] = 1.825-5.594, p < 0.001) and 4 (OR = 4.755, 95% CI = 2.715-8.325, p < 0.001), and participants in waist-to-calf circumference quartiles 2 (OR = 2.511, 95% CI = 1.397-4.511, p = 0.002), 3 (OR = 3.929, 95% CI = 2.076-7.435, p < 0.001), and 4 (OR = 5.298, 95% CI = 2.847-9.858, p < 0.001) had significantly greater risks of MetS; participants in waist-to-calf circumference quartile 4 (OR = 2.481, 95% CI = 1.477-4.167, p < 0.001) and participants in waist-to-calf circumference quartile 4 (OR = 1.763, 95% CI = 1.088-2.856, p = 0.021) had a significantly greater risk of AS, indicating that age-adjusted relative lower body circumferences associate with MetS and AS. Large thigh and calf circumferences may indicate reduced risks for cardiovascular disease. PMID- 27689564 TI - A new approach for speech synthesis in cochlear implant systems based on electrophysiological factors. AB - BACKGROUND: Speech synthesis models have been considered as viable tools for performance evaluation of cochlear stimulation algorithms, due to the difficulties of clinical tests. OBJECTIVE: The present study has developed a tool that can be used before any audio signal reconstruction algorithm, which shows more conformity with the electrophysiological parameters of the patient in evaluation of the cochlear implant stimulation algorithms. METHODS: In this method, excitable nerve fiber characteristics such as stimulation threshold and effective refractory period have been considered in the signal pre-reconstruction process. This algorithm subsumes the user's biological parameters (e.g., the manner of distribution of the remaining intact nerve fibers) as well as the stimulation signal parameters (e.g., stimulation rate, pulse width, amplitude of stimulation, the distance between stimulation electrode and fibers) in the signal pre-reconstruction. RESULTS: Effect of changes in these parameters can be observed by the number of excited fibers, which is directly related to the signal intensity and pitch frequency perceived by the user. The obtained results from simulations are in accordance with previous clinical findings. Also, the ability of the proposed tool can be seen by the correspondence between the results obtained from the proposed model and the amplitude growth functions of the cochlear implant users. CONCLUSIONS: This paper has introduced a tool for signal reconstruction from electrical stimulation so that a more comprehensive criterion for examination of the stimulating algorithms in cochlear implant can be achieved. PMID- 27689565 TI - Comparison of knee characteristics between professional and amateur golfers during the downswing. AB - Evaluating the biomechanical and performance factors of the knee joint during golf swing can provide objective and quantitative information about improving the performance and development of efficient physical training, as the legs are important for achieving an efficient swing and maximum speed of the club head in golf. In the present study, kinematic movements of the knee joint were identified during the downswing by using 3-dimensional motion analysis, and isokinetic strength was measured with driver and 5-iron clubs in 15 professional (PRO) golfers and 10 amateur (AMA) golfers. Results showed that PRO golfers had a narrower minimal angle between the thigh and lower leg in the trail knee than the AMA golfers, regardless of the club used, and the angular velocity of the lead knee was faster during the downswing with a 5-iron club in the AMA golfers than in the PRO golfers. The PRO and AMA golfers had a wider minimal angle between the thigh and lower leg, smaller total range of movement, and slower angular velocity of the trail knee when swinging a 5-iron club than when swinging a driver club. These results are expected to provide useful information to prevent golf-related injuries that usually arise in the knee joint and help improve the golf performance of amateur golfers. PMID- 27689566 TI - Comparison of distribution of lung aeration measured with EIT and CT in spontaneously breathing, awake patients1. AB - BACKGROUND: Both Electrical Impedance Tomography (EIT) and Computed Tomography (CT) allow the estimation of the lung area. We compared two algorithms for the detection of the lung area per quadrant from the EIT images with the lung areas derived from the CT images. METHODS: 39 outpatients who were scheduled for an elective CT scan of the thorax were included in the study. For each patient we recorded EIT images immediately before the CT scan. The lung area per quadrant was estimated from both CT and EIT data using two different algorithms for the EIT data. RESULTS: Data showed considerable variation during spontaneous breathing of the patients. Overall correlation between EIT and CT was poor (0.58 0.77), the correlation between the two EIT algorithms was better (0.90-0.92). Bland-Altmann analysis revealed absence of bias, but wide limits of agreement. CONCLUSIONS: Lung area estimation from CT and EIT differs significantly, most probably because of the fundamental difference in image generation. PMID- 27689567 TI - Effect of crosslinking methods on the structure and biocompatibility of polyvinyl alcohol/gelatin cryogels. AB - In this study, polyvinyl alcohol (PVA) and gelatin based cryogels were prepared by crosslinking chemically or physically for tissue engineering applications. Different PVA/Gelatin ratios (100:0, 90:10, 70:30, 50:50) and crosslinking methods have been used to prepare cryogels; chemical and physical structure of the prepared matrices were analysed by FTIR and SEM; swelling and degradation profiles were followed. Chemical and physical crosslinking was obtained by using glutaraldehyde as crosslinker and by applying freeze thawing cycle, respectively. Gelatin concentration and crosslinking method had significant effect on the pore size, swelling ratio and degradation profiles of the cryogels. Biocompatibility of the cryogels were also investigated by MTT assay. SEM was used to investigate the cell morphology on the scaffolds. The MTT assay findings prove that physically crosslinked PVA/Gelatin scaffolds are more biocompatible and enhance more the adhesion and proliferation of mouse embryonic fibroblast cells (MEF) than chemically crosslinked PVA/Gelatin scaffolds. The overall results demonstrated that, the PVA/Gelatin cyrogels as a suitable biomaterial for tissue engineering applications and crosslinking methods affect the architecture and characteristic properties of the cryogels. PMID- 27689568 TI - A study of the effect of clinical washing decontamination process on corrosion resistance of Martensitic Stainless Steel 420. AB - Corrosion of surgical instruments provides a seat for contamination and prevents proper sterilisation, placing both patients and medical staff at risk of infection. Corrosion can also compromise the structural integrity of instruments and lead to mechanical failure in use. It is essential to understand the various factors affecting corrosion resistance of surgical instruments and how it can be minimised.This paper investigates the effect on corrosion resistance from the clinical washing decontamination (WD) process, specifically by studying the changes in surface roughness and Cr/Fe ratio. Results indicate that the WD process provides a positive effect on smooth polished samples, while a lesser positive effect was observed on rough reflection reduced samples. PMID- 27689569 TI - Hemostyptic property of chitosan: Opportunities and pitfalls. AB - BACKGROUND: Chitosan is used in a wide field of applications and therapies and has been reported to be an effective hemostyptic. The objective of this study was to provide further information about the use of chitosan as a hemostyptic agent also taking into focus its hemocompatible effects. METHODS: Human whole blood (n=5) was anticoagulated with heparin, treated with different chitosan concentrations (0, 2.5, 5, 7.5, 10, 12.5, 25 mg/mL) and incubated at 37 degrees C for 30 minutes. Before and after incubation different parameters for coagulation and hemocompatibility were evaluated. RESULTS: Blood treated with high chitosan concentrations showed enhanced coagulation, which we evaluated with activated clotting time, activated partial thromboplastin time and concentration of thrombin-antithrombin complexes. Furthermore, we observed an activation of blood platelets, complement cascade and granulocytes in the groups treated with chitosan. CONCLUSION: Our data indicate that chitosan activates human blood coagulation and hence has good properties as a hemostyptic agent. However, inflammatory parameters were upregulated after direct contact with human blood indicating that systemic administration of chitosans should not be performed whereas the topical use of chitosan as a hemostypticum should not present any hazard with regard to adverse inflammatory reactions at the site of application. PMID- 27689570 TI - Influence of tooth brushing on adhesion strength of orthodontic brackets bonded to porcelain. AB - BACKGROUND: Adhesive resin composite, which is used to bond orthodontic bracket to tooth surface is exposed to the influence of wear by tooth brushing and wear may influence loosening of the bracket. OBJECTIVE: The aim of this study was to evaluate in vitro the effect of tooth brushing on the adhesion strength of orthodontic brackets bonded to surface treated porcelain. METHOD: A total of 90 glazed porcelain fused to metal facets (PFM) were randomly assigned into 3 groups according to the surface treatment to be received. Group 1 was conditioned with hydrofluoric acid (HF), group 2 conditioned with grit-blasting (GB) and group 3 conditioned with tribochemical silica coating (RC). The groups were evaluated for surface roughness (Ra) before and after surface treatment. Next, 15 samples from each group were subjected to brushing and remaining 15 samples served as the baseline (n=15). Adhesion strength (shear bond strength)was recorded using a universal testing machine. Data collected were analyzed by ANOVA and Tukey's multiple comparison post hoc analysis. RESULTS: Tooth brushing decreased the bond strength in all groups. The highest adhesion strength (baseline and after brushing) was observed in group 3 (26.8 +/- 1.77 MPa and 23.57 +/- 1.02 MPa) and the lowest was found in group 1 (9.6 +/- 1.5 MPa and 5.87 +/- 0.77 MPa). Group 3 specimens exhibited the highest Ra (1.24 +/- 0.08). CONCLUSION: It was found that tooth brushing of the exposed adhesive resin composite at the bracket-bonding substrate interface lowers the bonding strength regardless of the surface treatment of the substrate. PMID- 27689571 TI - Orthodontic tunnel miniscrews with and without TiO2 nanotube arrays as a drug delivery system: In vivo study. AB - Orthodontic tunnel miniscrews with and without TiO2 nanotube arrays were fabricated to improve the induction of new bone formation and osseointegration. To inject the drug of recombinant human bone morphogenetic protein, tunnels in a conventional machined miniscrew were machined by a computer-numerical-control lathe. TiO2 nanotube arrays to load the drug were also formed on the surface of the tunnel miniscrew by anodic oxidation. To obtain clean TiO2 nanotube arrays, two-step anodic oxidation was conducted. The diameters of TiO2 nanotube window and TiO2 nanotube were ~70 nm and ~110 nm, respectively. Three groups, i.e., a conventional machined miniscrew, a tunnel miniscrew without TiO2 nanotube arrays, and a tunnel miniscrew with TiO2 nanotube arrays, were prepared and inserted in the legs of five New Zealand White rabbits. In a histomorphometric analysis, the bone implant contact ratios of the tunnel miniscrews with the TiO2 nanotube arrays and without the TiO2 nanotube arrays were 5.84% and 5.88%, respectively. These values were higher than the value of 4.30% for the conventional machined miniscrew. The bone surface ratios in the tunnel miniscrew with and without the TiO2 nanotube were also higher than those of the conventional machined miniscrew. The measured values of the tunnel miniscrew with and without the nanotube and the conventional miniscrew were 76.75%, 73.41%, and 44.82%, respectively, although the differences were statistically insignificant. New bone at three weeks and six weeks after the operations were found in the tunnel miniscrews in fluorescent images. Both the tunnel miniscrews with and without the TiO2 nanotube arrays demonstrated greater bone formation compared to the conventional miniscrews. However, TiO2 nanotube arrays was not likely to provide additional benefit to the tunnel miniscrew. An in vivo study suggested that the tunnel fabricated in the miniscrew can be efficient drug-delivery systems to improve osseointegration. PMID- 27689572 TI - Interfragmentary motion assessment for three different fixation techniques of femoral neck fractures in young adults. AB - BACKGROUND: Vertical femoral neck fractures in the youth could be happened in high-energy accidents, and because of dominant shearing forces, this fracture is considered as a troublesome injury with a controversy regarding selection of the best fixation method. OBJECTIVE: The long term goal of this quasi-experimental study was to find the more stable fixation method among cannulated screws (CSs), proximal femoral locking plate (PFLP), and dynamic hip screw with derotational screw (DHS+DS) for this kind of fracture. METHODS: Twelve fresh-frozen cadaveric femurs were assigned to three groups that were matched for mean bone mineral density and stiffness of intact bone. Vertical fractures were artificially mimicked in the specimens and fixed using three different implants, i.e. CSs, PFLP, and DHS+DS. Then, the samples were tested under incremental, cyclic, and failure loading phases. RESULTS: The differences in all biomechanical parameters were statistically significant among tested groups (p<0.05). All biomechanical parameters for the DHS+DS method of fixation are significantly different from those corresponding to CSs (p<0.05). There were no significant differences in failure load and failure energy between the PFLP and CSs techniques (p>0.05). Also, there were no significant differences in relative stiffness and femoral head displacement between the PFLP and DHS+DS groups (p>0.05). CONCLUSIONS: Based on the clinical assumption that restricted weight-bearing regimen is recommended in the postoperative rehabilitation protocol, the results of this study suggest that the priority order of selection for the stable fixation implant of vertical femoral neck fracture in young patients is DHS+DS, then PFLP, and finally CSs.

AB - BACKGROUND: Red blood cell (RBC) susceptibility to hemolysis - or fragility - can be profiled by subjecting a sample to progressive durations of mechanical stress and measuring hemolysis upon each. The ability to control stress application with multiple variable parameters can be useful in various areas of research. Bead milling, by oscillating an object in a blood sample, can offer control of parameters including oscillation force and frequency. OBJECTIVE: This work addresses the role of bead shape and size, for a given container, in potentially creating qualitatively as well as quantitatively different fluidic stresses in the sample. METHODS: Identical, diluted RBC samples were stressed via bead milling using different beads, with other parameters the same. Resulting hemolysis was plotted for several time increments in each case. RESULTS: For a cylindrical bead oscillating at a given frequency and force, bead length was a determinant of albumin's protective effect on RBC, as reflected by mechanical fragility. Compared to a sphere of same diameter, the protective effect was absent with shorter cylinders, whereas for longer ones it appeared enhanced. CONCLUSIONS: Bead milling based RBC fragility testing could present a useful tool for creating, and studying effects of different shear stress types in inducing hemolysis.

AB - Existing scaffolds cannot adequately satisfy the simultaneous requirements for the regeneration of bone. The challenge remains of how to improve the integration of newly formed bone with the surrounding tissues. The purpose of this study was to investigate the effects of two silk fibroin scaffolds, a hexafluoro isopropanol-based silk fibroin (HFIP-F) and an aqueous-based silk fibroin (A-F), for their osteoinductive potentials in large critical size bone defects in vivo. beta-tricalcium phosphate (beta-TCP) was used as a positive control. After implantation into defects created in the knee joints of rabbits for 1 and 2 weeks, hematoxylin and eosin (H-E) and Azan staining revealed that the A-F scaffold as well as beta-TCP had stronger osteoinductive ability than the HFIP-F scaffold. The A-F scaffold exhibited prominent areas of neo-tissue containing bone-like nodules. Furthermore, induced osteointegration was observed between native and neo-tissue within the osteo defects in the knee joints of rabbits. Immunohistochemical staining showed the highest expression of Runx2, BMP-2, BMP 7, Smad1/5/9 and Phospho-Smad in the A-F scaffold implants. Osteoinduction of the porous A-F scaffold might be influenced by the amount of BMP signaling present in the local microenvironment in the implants. This study opens a new avenue to use A-F silk fibroin scaffolds for the regeneration of bone defects.

AB - Bioactive glass (BG)-containing fiber-reinforced composite implants, typically screw-retained, have started to be used clinically. In this study, we tested the mechanical strength of composites formed by a potential implant adhesive of n butyl-2-cyanoacrylate glue and BG S53P4 particles. Water immersion for 3, 10 or 30 days had no adverse effect on the compression strength. When cyanoacrylate glue-BG-composites were subjected to simulated body fluid immersion, the average pH rose to 7.52 (SD 0.066) from the original value of 7.35 after 7 days, and this pH increment was smaller compared to BG particle-group or fibrin glue-BG composite group. Based on these results n-butyl-2 cyanoacrylate glue, by potentially producing a strong adhesion, might be considered a possible alternative for fixation of BG S53P4 containing composite implants. However, the mechanical and solubility properties of the cyanoacrylate glue may not encourage the use of this tissue adhesive with BG particles. PMID- 27689576 TI - The demands and benefits of ergonomics in Sri Lankan apparel industry: A case study at MAS holdings. AB - BACKGROUND: Apparel exports bring in sizeable foreign income to Sri Lanka. To protect and promote this industry is a paramount need. This can be carried out by applying Human Factors/Ergonomics (HFE) which has proved to control negative effects at work places. OBJECTIVES: This paper reports a case study which describes the demands and benefits of HFE in MAS Holdings which owns a large share of the apparel industry in Sri Lanka. METHODS: The study consisted of walk through observation survey, a questionnaire survey and ergonomic work place analysis followed by a training programme to selected employees in three companies. RESULTS: Positive responses to questionnaires revealed good ergonomic practices in the work places surveyed. Ergonomically unfit chairs and potential hazards e.g. exposure to noise and hot environment were detected. It is seen that MAS have introduced strategies originated by Toyota Production System viz. 5S, Kaizen, six sigma etc., which are in fact ergonomic methods. A progressive project MAS boast of viz. 'MAS Operating System' (MOS) empowers training and development to employees. CONCLUSIONS: MAS Holdings has adequately realized the benefits of applying HFE as evident by the number of awards received. Relevant companies were advised to take appropriate corrective measures to control the potential hazards. PMID- 27689577 TI - Tool development to assess the work related neck and upper limb musculoskeletal disorders among female garment workers in Sri-Lanka. AB - BACKGROUND: Musculoskeletal disorders (MSDs) have been identified as a predisposing factor for lesser productivity, but no validated tool has been developed to assess them in the Sri- Lankan context. OBJECTIVE: To develop a validated tool to assess the neck and upper limb MSDs. METHODS: It comprises three components: item selections, item reduction using principal component analysis, and validation. A tentative self-administrated questionnaire was developed, translated, and pre-tested. Four important domains - neck, shoulder, elbow and wrist - were identified through principal component analysis. RESULTS: Prevalence of any MSDs was 38.1% and prevalence of neck, shoulder, elbow and wrist MSDs are 12.85%, 13.71%, 12%, 13.71% respectively. Content and criterion validity of the tool was assessed. Separate ROC curves were produced and sensitivity and specificity of neck (83.1%, 71.7%), shoulder (97.6%, 91.9%), elbow (98.2%, 87.2%), and wrist (97.6%, 94.9%) was determined. Cronbach's Alpha and correlation coefficient was above 0.7. CONCLUSION: The tool has high sensitivity, specificity, internal consistency, and test re-test reliability. PMID- 27689578 TI - Improving performance and happiness among healthcare workers through a body-mind approach in a healthcare setting in Sri Lanka. AB - BACKGROUND: Cognitive ergonomics in the work place has become a serious concern with the need to keep people happy at work while maintaining high productivity. Hence, it is worth exploring how the outcomes of lifestyle-based mind development programs can bring about happiness in workplace while keeping productivity and quality of services high. OBJECTIVE: The objective of the present work was to test a body-mind technique to improve cognitive ergonomics in a health care work setting. METHODS: Principal investigator explored many body-mind techniques before selecting the present method of "insight meditation" which he mastered before applying it on a group of scholars who made it a part of their lifestyle. Later it was introduced to a sample of 500 volunteer health personnel in the western province to generate a ripple effect of happiness at work. RESULTS: Initial qualitative information indicated improvement of some aspects of cognitive ergonomics among those who practiced it. There was a relief from stress during the practice sessions and improvements in the commitment to work and in team spirit. A demand was observed for further training. A quasi-experimental study to test the improvements is underway. CONCLUSIONS: Health workers showed interest in the mind training and potential benefits to individuals and the institutions were observed. PMID- 27689579 TI - Knowledge, attitudes and practices regarding handling mercury containing medical devices among nurses in a tertiary care paediatric hospital in Sri Lanka. AB - BACKGROUND: Mercury is a highly toxic heavy metal used in many medical devices in the healthcare sector, making nurses one of the vulnerable occupational groups. OBJECTIVE: To assess knowledge, attitudes and practices regarding handling mercury containing devices and factors associated with knowledge among nurses in a paediatric hospital in Sri Lanka. METHODS: A descriptive cross-sectional study was conducted among nurses (n = 538) working in Lady Ridgeway Hospital, Sri Lanka. Information on the use of mercury containing medical devices, accidental exposure, management of spillage and disposal was gathered using a self administered questionnaire. RESULTS: A total of 472 nurses responded with a response rate of 87.7%. Of the 347 mercury thermometer users, 67.1% had experienced breakages while among 405 mercury sphygmomanometer users, 20.0% had experienced mercury spillages, during a three months period prior to the study. A majority (56.8%) had 'good' overall knowledge regarding mercury and its adverse effects while 94.1% had favorable attitudes towards protecting themselves/others from mercury. Practices related to managing a mercury spill were poor. Work experience >10 years (p = 0.032) and favorable attitude (p = 0.007) were associated with good knowledge while having a training on managing a mercury spillage was not (p = 0.850). CONCLUSIONS: Gaps in practices on managing a mercury spillage were evident. Current training programmes were not found to be effective. PMID- 27689580 TI - Occupational health issues in small-scale industries in Sri Lanka: An underreported burden. AB - BACKGROUND: Work-related diseases and occupational accidents affect a significant number of workers globally. The majority of these diseases and accidents are reported from developing countries; and a large percentage of the workforce in developing countries is estimated to be employed in small-scale industries. Sri Lanka is no exception. These workers are exposed to occupational hazards and are at a great risk of developing work- related diseases and injuries. OBJECTIVE: To identify occupational health issues faced by small-scale industry workers in Sri Lanka. METHODS: A cross sectional study was conducted among workers in four selected small-scale industry categories in two districts of Sri Lanka. A small scale industry was defined as a work setting with less than 20 workers. Cluster sampling using probability proportionate to size of workers was used. Eighty clusters with a cluster size of eight from each district were selected. Data was collected using a pre-tested interviewer administered questionnaire. RESULTS: Our study surveyed 198 industries. Headache (2.2%, 95% CI 1.5-3.1) and eye problems (2.1%, 95% CI 1.4-2.9) were the commonest general health issues detected. Back pain (4.8%, 95% CI 3.8-6.1) was the most prevalent work-related musculoskeletal pain reported. Knee pain was the second highest (4.4%, 95% CI 3.4-5.6). Most of the work-related musculoskeletal pain was either of short duration or long lasting. CONCLUSIONS: Work-related musculoskeletal pain was much more common than the general health issues reported. Health promotional programs at workplaces focusing ergonomics will benefit the workers at small-scale industries inSri Lanka. PMID- 27689581 TI - Burden of lupus on work: Issues in the employment of individuals with lupus. AB - BACKGROUND: Systemic lupus erythematosus (SLE) or Lupus is one of the leading causes of work disability in the United States, accounting for about 20% of the more than estimated 1.5 million Americans with a work disability. The symptoms of lupus can have a profound impact on the person's employment. Impacts of lupus are more pronounced among young and middle-adulthood. Studies have shown that loss in work hours cost the nation nearly $13 billion annually. The loss also impacts the individual's work, quality of life, self-management, and self-efficacy. OBJECTIVE: In this article, the author describes the financial burden of lupus. The article also describes the substantial impact of lupus on employment outcomes for individuals living with the condition. The author also reviews major signs and symptoms of disease and their impact on employment. RESULTS: Findings from this research can be used to identify various accommodations and strategies for individuals to prevent flare-ups. CONCLUSIONS: The paper presents innovative strategies that include early interventions and how employers andco-workers can provide helpful support that includes job accommodations to individuals with lupus. PMID- 27689582 TI - Methods of 3D data applications to inform design decisions for physical comfort. AB - BACKGROUND: Past research on anthropometry, especially in the industry of external ear worn products, stresses that positive comfort is enhanced when there is sufficient knowledge of human factors; however, most anthropometric studies focus only on the acquirement and presentation of data. OBJECTIVE: The aim of this paper is to provide with different methods to support design applications of 3-dimensional head and ear data with a focus on external ear products. METHODS: Two hundred persons representing the Danish population were scanned. The 3D data was collected, refined and analysed in 3 meaningful ways: Advanced geometry, visualisations of data and for the generation of archetypes. RESULTS: A matrix containing 29 new ear dimensions was generated. The application of methods led to the development of 9 additional dimensions. The paper finally presents all phases of the analysis of the 3D data in the form of a methodological framework. CONCLUSIONS: The paper contributes with, in addition to the methodological framework, techniques to extract data based on product understanding and how the data can be used to define archetypes for focus groups and other qualitative assessments. In their endeavour to develop successful and comfortable products designers should focus more on fitting the task into the human by benchmarking human dimensions against product data. PMID- 27689583 TI - Integrating ergonomics knowledge into business-driven design projects: The shaping of resource constraints in engineering consultancy. AB - BACKGROUND: The integration of ergonomics knowledge into engineering projects leads to both healthier and more efficient workplaces. There is a lack of knowledge about integrating ergonomic knowledge into the design practice in engineering consultancies. OBJECTIVES: This study explores how organizational resources can pose constraints for the integration of ergonomics knowledge into engineering design projects in a business-driven setting, and how ergonomists cope with these resource constraints. PARTICIPANTS: An exploratory case study in an engineering consultancy was conducted. A total of 27 participants were interviewed. METHODS: Data were collected applying semi-structured interviews, observations, and documentary studies. Interviews were transcribed, coded, and categorized into themes. RESULTS: From the analysis five overall themes emerged as major constituents of resource constraints: 1) maximizing project revenue, 2) payment for ergonomics services, 3) value of ergonomic services, 4) role of the client, and 5) coping strategies to overcome resource constraints. CONCLUSION: We hypothesize that resource constraints were shaped due to sub-optimization of costs in design projects. The economical contribution of ergonomics measures was not evaluated in the entire life cycle of a designed workplace. Coping strategies included teaming up with engineering designers in the sales process or creating an alliance with ergonomists in the client organization. PMID- 27689584 TI - Ergonomic workplace assessment in orthotic and prosthetic workshops. AB - BACKGROUND: In Iranian orthotic and prosthetic workshops, the majority of activities are carried out by manpower and the tasks are labor-intensive. In these workshops, ergonomic aspects of working conditions are seldom considered. OBJECTIVE: This study was conducted in orthotic and prosthetic workshops with the objectives of determination of prevalence rate of MSDs among employees and assessment of ergonomics working conditions. METHODS: In this cross-sectional study, all employees (n = 42; 29 males and 13 females) in 11 active orthotic and prosthetic production centers of Shiraz city participated. Data were collected using Nordic Musculoskeletal disorders Questionnaire (NMQ) and observational technique by an ergonomics checklist for assessment of working conditions. RESULTS: The means (SD) of age and job tenure (years) in the study individuals were 37.26 (10.21) and 12.8 (9.39), respectively. The most prevalent MSD symptoms in the past 12 months were reported in the lower back (42.9%), shoulders (40.5%) and knees (40.5%). Working conditions assessment showed that the main ergonomic problems in the workshops studied originated from awkward working posture, improper workstation design, poorly designed hand tools and incorrect manual material handling. CONCLUSION: Any interventional program for working conditions improvement should, therefore, focus on these areas. PMID- 27689585 TI - From the Editor. PMID- 27689586 TI - The effectiveness of rehabilitation on pain-free farming in agriculture workers with low back pain in India. AB - BACKGROUND: Studies have shown that farming is associated with many agricultural workers experiencing low back pain (LBP). The rehabilitation of these workers should facilitate their functioning, activities and level of participation in an adequate way. OBJECTIVE: The objectives of this study were to identify the health components associated with LBP and to evaluate the effectiveness of the interventions in returning agricultural workers with LBP to their vocation using the International Classification of Function (ICF) -based tools. METHODS: Thirty one full time agricultural workers from 3 different Indian states were prospectively assessed using the ICF core set for LBP. ICF core sets permitted analysis of limitations of function from both the participant and rehabilitation team's perspectives. Each ICF category was rated using an ICF qualifier. The components identified were linked to the ICF categorical profile and assessment sheet. The clinicians identified the global, service program and cycle goals based on ICF. The participants' functioning was followed over a 4-month period. RESULTS: After intervention, the participants were able to undergo their routine activities without increases in pain. However, on returning to active farming, participants noted few improvements in the components d410 (changing basic body position), d415 (maintaining body position), d430 (lifting and carrying objects), d465 (moving around using equipment), d850 (remunerative employment) and d859 (work and employment, other specified and unspecified). CONCLUSION: The results of the study conclude that the current interventions for LBP are not effective in returning agriculture workers with LBP in India to pain-free farming. There is an urgent need to individualize the health needs of agriculture workers. PMID- 27689587 TI - Insufficient time for leisure and perceived health and stress in working parents with small children. AB - BACKGROUND: More knowledge about how recovery may promote health among parents with small children is needed. OBJECTIVE: To explore whether insufficient time for leisure was associated with poorer perceived health and higher stress in working parents. A further aim was to explore potential gender differences in the association between insufficient time for leisure and poor perceived health. METHODS: A postal survey including the perceived stress scale and three measures of subjective health - self-rated health (SF-36), work-related fatigue (Swedish occupational fatigue questionnaire), and Lund subjective health complaints - as well as questions about time for leisure was completed by 965 women and 597 men. Risk ratios for poor perceived health and stress were estimated using Poisson regression, in which also gender interaction was analysed. RESULTS: The results showed higher risk for perceived stress among parents reporting insufficient time for relaxation, and more subjective health complaints among those reporting insufficient time to spend with their children. Overall, effects were larger among women than among men. CONCLUSION: A good balance between work and leisure seems to be of importance for working parents' perceived health and stress. PMID- 27689588 TI - The role of psychosocial and physical work-related factors on the health-related quality of life of Iranian industrial workers. AB - BACKGROUND: The role of psychosocial and physical work factors in predicting health related quality of life (HRQOL) has not been investigated among Iranian industrial workers. OBJECTIVE: The present study is designed to assess these relationships among Iranian workers from steel and cosmetic factories. METHODS: A cross-sectional study was conducted among 280 workers from two factories. Psychosocial and physical work factors and HRQOL were measured by the Persian translations of the following questionnaires: Job Content Questionnaire (JCQ) and the World Health Organization Quality of Life-Brief (WHOQOL-Brief). An instrument was developed to assess socio-demographic, health, and other work-related factors. The data were analyzed using independent t-tests, Pearson product moment correlation and hierarchical multiple regression. RESULTS: Results revealed that the respondents generally had poor HRQOLs especially in the environmental domain. The steel factory workers who were exposed to higher levels of occupational risk factors suffered from poorer HRQOL compared to the cosmetic factory workers. The results of hierarchical regression for all participants revealed that social support, sleep quality, work schedule, smoking and exercise were significant predictors of all domains of HRQOL. CONCLUSIONS: To improve the worker's HRQOL, intervention programs should focus on promoting social support, sleep quality, exercise and smoking habits. Moreover, reducing hazardous work environments should be considered an important intervention to promote HRQOL. PMID- 27689589 TI - Stuck in the middle: The emotional labours of case managers in the personal injury compensation system. AB - BACKGROUND: Case managers within injury compensation systems are confronted with various emotional demands. OBJECTIVE: Employing the concept of emotional labour, this paper explores distinctive aspects of these demands. METHODS: The findings are drawn from focus groups with 21 Australian case managers. RESULTS: Case managers work was characterised by extra-role commitments, emotional control, stress and balancing tensions arising from differing stakeholder expectations about outcomes related to compensation and return to work. CONCLUSIONS: By examining the experiences of case managers, the findings add to the literature on the emotional labour of front line service workers, especially with respect to the demands involved in managing the conflicting demands of work. PMID- 27689590 TI - Interventions to reduce injuries among older workers in agriculture: A review of evaluated intervention projects. AB - BACKGROUND: The number of older workers is increasing throughout the industrialised world and older workers are known to be more frequent in the injury-prone agricultural sector. OBJECTIVE: This paper sought to extend knowledge by reviewing evaluated intervention studies intended to decrease risks and work injuries among older workers in agriculture. METHODS: A systematic literature review regarding: evaluated intervention projects on injury prevention, including participants aged 55 years and older, and working in agriculture. RESULTS: This review identified evaluated intervention projects regarding: i) intervention in injury prevention; ii) interventions to increase knowledge in health and safety tasks and practice; and iii) interventions to increase the use of safety equipment in work. The evaluations reviewed showed that the interventions were less successful in involving older agricultural workers than their younger counterparts. The evaluations also showed that the outcome of interventions was generally less positive or brought about no significant difference in risk awareness and behaviour change among older agricultural workers. CONCLUSIONS: Many articles and statistics describe injuries in agriculture. Especially older farm workers are one of the groups with most work injuries and deaths. Despite this, an important finding in this review was shortage of implemented and evaluated intervention studies orientated toward reduce injuries among older workers in agriculture. This review also found that no intervention project in the evaluations studied had a clear positive effect. Many intervention studies have problems with or lack of evaluation in the study design. Based on the results in this review, important future research tasks are to improve the design of interventions, devise implementation methods and formulate appropriate evaluation methods to measure the outcome of the interventions. Intervention programmes also need to involve older workers specific physical and cognitive age aspects in the design to increases their willingness to participate and to be successful to reduce injuries. PMID- 27689591 TI - Elucidating the relationship between work attention performance and emotions arising from listening to music. AB - BACKGROUND: In addition to demonstrating that human emotions improve work attention performance, numerous studies have also established that music alters human emotions. Given the pervasiveness of background music in the workplace, exactly how work attention, emotions and music listening are related is of priority concern in human resource management. OBJECTIVES: This preliminary study investigates the relationship between work attention performance and emotions arising from listening to music. PARTICIPANTS: Thirty one males and 34 females, ranging from 20-24 years old, participated in this study following written informed consent. METHODS: A randomized controlled trial (RCT) was performed in this study, which consisted of six steps and the use of the standard attention test and emotion questionnaire. RESULTS: Background music with lyrics adversely impacts attention performance more than that without lyrics. Analysis results also indicate that listeners self-reported feeling "loved" while music played that implied a higher score on their work-attention performance. Moreover, a greater ability of music to make listeners feel sad implied a lower score on their work-attention performance. CONCLUSIONS: Results of this preliminary study demonstrate that background music in the workplace should focus mainly on creating an environment in which listeners feel loved or taken care and avoiding music that causes individuals to feel stressed or sad. We recommend that future research increase the number of research participants to enhance the applicability and replicability of these findings. PMID- 27689592 TI - Health promotion in the trucking setting: Understanding Dutch truck drivers' road to healthy lifestyle changes. AB - BACKGROUND: The working environment, the nature of the work, and the characteristics of truck drivers as a social group typically pose great challenges for the truck drivers' health and health promotion activities aiming to improve it. OBJECTIVE: The purpose was to obtain a better understanding of (a) Dutch truck drivers' perceptions of health and lifestyle themes, and (b) the challenges they experience in their pursuit of a more healthy lifestyle, as a guiding framework for the development of health interventions targeting this occupational group. METHODS: In this qualitative study, we conducted and analyzed 20 semi-structured interviews and seven cases of participant observations with Dutch truck drivers. Grounded theory was used to analyze the data. RESULTS: Our findings illustrate that Dutch truck drivers wish to improve their lifestyle but have unproductive associations with concepts of healthy living as well as a tendency to downplay their health risks. In addition, they experience barriers within their work and personal environment that prevent them from translating their intentions into actual lifestyle changes. CONCLUSIONS: Based on the insights derived from the interviews, we discuss recommendations for the development of more effective health promotion interventions for truck drivers. PMID- 27689593 TI - Uprising: An examination of sit-stand workstations, mental health and work ability in sedentary office workers, in Western Australia. AB - BACKGROUND: Office-based staff spend around three quarters of their work day sitting. People who sit for long periods while at work are at greater risk of adverse health outcomes. OBJECTIVE: The pilot study aimed to determine the effect of sit-stand workstations on office-based staff sedentary and physical activity behaviors, work ability and self-reported physical and mental health outcomes. METHODS: A two-group pre-post study design assessed changes in sedentary and physical activity behaviors (time spent sitting, standing and stepping and sit stand transitions and number of steps taken) work ability and physical and mental health. Physical activity behaviors were measured using activPAL activity monitors and self-reported data on work ability and physical and mental health were collected using an online questionnaire. RESULTS: Relative to the controls (n=19), the intervention group (n=18) significantly decreased time spent sitting by 100 minutes (p<0.001) and increased standing time by 99 minutes (p<0.001). There was a decrease in self-reported current work ability when compared to lifetime best (p=0.008). There were no significant differences for all other sedentary behavior, other workability outcomes, physical health or mental health outcomes at follow-up. CONCLUSIONS: The Uprising Study found that sit-stand workstations are an effective strategy to reduce occupational sitting time in office-based workers over a one month period. PMID- 27689594 TI - Small opportunities are often the beginning of great enterprises: The role of work engagement in support of people through the recovery process and in preventing relapse in drug and alcohol abuse. AB - BACKGROUND: This study, carried out in five Therapeutic Communities (TCs), aims to evaluate the relationship between social support and sense of community for people with pathological addictions and the personal and professional dimensions of hope, resilience, work engagement, future time perspective, and job performance. Support to the person is attained through social support at work by the supervisor and the person's sense of belonging to the community. OBJECTIVE: The purpose of this article is to analyze the relationship between social support, sense of community, hope, resilience, work engagement, future time perspective, and job performance. METHODS: In order to verify the relations between those variables, structural equation models with observed variables (path analysis) were estimated using LISREL 8.80. RESULTS: The results show a direct relationship between social support at work by the supervisor and hope, as well as between sense of community and resilience at work, while work engagement plays a mediating role between the two antecedents and the personal and professional variables investigated - hope, resilience, future time perspective and performance at work. Performance was measured through both people's self perceptions and their supervisors' evaluations. A positive correlation exists between the two assessments. CONCLUSIONS: The positive consequences of the research entail both theoretical and practical aspects. PMID- 27689595 TI - Australian fly-in, fly-out operations: Impacts on communities, safety, workers and their families. AB - BACKGROUND: Australia's mineral, resource and infrastructure sectors continues to expand as operations in rural and remote locations increasingly rely on fly-in, fly-out or drive-in, drive-out workforces in order to become economically competitive. The issues in effectively managing these workforces are becoming more apparent with reported high amounts of turnover and concerns for safety and performance. The issues presented include a range of physical, mental, psychosocial, safety and community challenges. OBJECTIVES: This review aims to consolidate a range of research conducted to communicate potential challenges for industry in relation to a wide variety of issues when engaging and using FIFO/DIDO workforces which includes compressed working schedule design (work schedules), working hours, fatigue, safety performance, employee wellbeing, turnover, psychosocial relationships and community concerns. METHODS: A comprehensive literature review was performed using EBSCOhost, PubMed and google scholar, with a focus on FIFO or DIDO workforces engaged within the resources sector. Search terms were kept broad in order to capture all national and international research conducted and included: "fly-in, fly-out" "FIFO" "DIDO" "drive-in, drive-out" "mining". There was no date restriction included in the search. RESULTS: Many of the studies were focused on sleep quality, fatigue and the influence of lowered safety performance while at work, presenting an increased risk for health and safety. These issues may be exacerbated for the FIFO workforce when linked to additional research surrounding the extended periods of absence from families influencing workers personal relationships, psychological wellbeing, job satisfaction and the reported high amounts of turnover within the industry. Taken together, this presents a unique implication for the management and continued use of FIFO workforces when considering balancing safety and performance with economic viability of production and operations. CONCLUSIONS: The issues of long working hours, fatigue, turnover and job satisfaction are not new to the management of workers. However, FIFO workforces appear to be at an increased risk physically and mentally due to a culmination of other influences, such as extended and frequent periods of absence from friends and families which contribute to feelings of isolation and lowered psychological wellbeing. FIFO workers and their families, engage in a unique lifestyle, rarely are other workers subjected to long hours and compressed work weeks while separated or isolated from their families for extended periods of time. Recently, FIFO interest has shifted to understanding the influences on employee engagement, satisfaction, retention and safety. Considering the management of FIFO workforces from a holistic perspective incorporating all of the issues impacting on these workers may assist to ensure the challenges associated with FIFO employment are understood, addressed and communicated to workers and their families is crucial for safety and health. PMID- 27689596 TI - Health promotion in workplaces as a strategy for modification of risk factors for Non Communicable Diseases (NCDs): A practical example from Sri Lanka. AB - BACKGROUND: Non communicable diseases (NCDs) are emerging as a major public health concern worldwide and became a leading cause of mortality in Sri Lanka accounting for 65% of deaths. Health promotion strategies aimed at lifestyle modification are helpful in modifying risk factors for NCDs. OBJECTIVES: To transform a workplace to a health promotion setting where lifestyle changes in workers lead to a modification of risk factors for NCDs. METHODS: A health promotion program was conducted in a divisional administrative office, in Sri Lanka. An office health promotion committee was established and an action plan was prepared with participation of the workers. An interviewer administrated questionnaire was used to assess risk factors for NCDs. Workers were then screened for NCDs. Behavioral change and communication (BCC) programs were conducted to improve physical activity and dietary modifications. RESULTS: Workers actively participated realizing the ownership of their health. 32 males and 49 females (mean age of 40.8 years) were assessed. Among them, 23.4% were overweight and obese while 26% reported physical inactivity. Among males, 12.5% were smokers. Hypertension and dyslipidaemia were present among 9.9% and 12.3%, respectively. 6.2% had high fasting blood glucose values. The program resulted in identifying 12 new patients with NCDs. After initiating health promotion activities, smoking rate dropped by 75%. Physical inactivity was reduced by 14% and consumption of fresh fruits and vegetables increased by 19%. CONCLUSIONS: Programs targeting office settings are a new strategy for reduction of NCDs in Sri Lanka. True benefit of risk factor modification through BCC programs will become apparent in longitudinal assessments. PMID- 27689597 TI - Sri Lanka: Adding Ergonomics Dimension in the Health Agenda. PMID- 27689598 TI - Ergonomic footwear for Sri Lankan primary schoolchildren: A review of the literature. AB - BACKGROUND: Foot ailments are common among schoolchildren, some of which may be attributed to wearing ill-fitting footwear. As schoolchildren often participate in athletic activity, they are doubly vulnerable to foot ailments, and are particularly vulnerable to conditions such as hallux valgus, Achilles tendonitis, athlete's foot, corns and calluses. Thus, there is an acute need for the design and manufacture of ergonomic footwear for this target group. While research on appropriate footwear for children has been carried out in relation to child populations in other societies, research on the circumstances of Sri Lankan schoolchildren is lacking. Neither the requisite design know-how nor the information for design is available to footwear manufacturers. OBJECTIVES: This review of the literature is aimed at confirming the need for ergonomic footwear from the point of view of the effects of wearing ill-fitting shoes and at identifying the requirements in terms of design information, especially for schoolchildren of the age group five to ten years, to empower footwear manufacturers. METHODS: PubMed, Google scholar and Science Direct were used for the literature search. RESULTS: 208 publications were read in full, 94 of which are referenced in this review. CONCLUSION: The review shows morphological measurements, behavior and activity patterns of schoolchildren and environmental conditions they are exposed to should be determined to formulate design information.

PMID- 27689600 TI - Important skills for biomedical services: The perspectives of Malaysian employers and employees. AB - BACKGROUND: Increase in the occurrence of existing diseases, continual emergence of new or exotic diseases and re-emergence of old diseases have placed increasing demands on biomedical services in Malaysia. Biomedical technicians play an important role in operating biomedical instruments. However, there are no clear specifications about characteristics and traits for these semi-professional employees. Employers in a few studies claimed that biomedical graduates are not ready to enter and face challenges in the job market. OBJECTIVE: Therefore, the purpose of this study is to identify technical and generic skills for a biomedical technician from the perspectives of the biomedical technicians and their employers. METHODS: A quantitative survey design was employed whereby data were obtained through the administration of an instrument developed by the researchers. The sample consisted of 20 hospital managers and 186 biomedical technicians who are currently working in Malaysian government hospitals. RESULTS: The findings show that there are no difference in the perceptions of hospital managers and biomedical technicians regarding technical and non-technical skills. CONCLUSIONS: These findings resulted in a checklist which can be used for institutions to produce future biomedical technician graduates in order to meet job demands. However, future research is needed to validate the findings and explore the variables in depth. PMID- 27689601 TI - The aetiologies of Failed Back Surgery Syndrome: A systematic review. AB - PURPOSE: Four to fifty percent of patients will develop Failed Back Surgery Syndrome (FBSS) following lumbar spine surgery. Repeated surgeries lead to escalating costs and subsequent decreases in success rate. Much of the research to date has focused on the psychosocial factors associated with FBSS. All factors including physical and pathological aetiologies should be examined. These factors may be independent, co-exist with or predispose patients to the psychological factors associated with FBSS. Previous reviews on the topic have been limited by a lack of systematic overview. The aim of this review is to identify the physical, physiological and pathological aetiologies of FBSS. METHODS: This review was done in accordance with the PRISMA guidelines. A computer-aided search of the electronic databases from inception to December 2014 was performed. Outcome measures of interest included pain, functional and radiological assessments. Two reviewers independently selected studies for inclusion. Methodological quality was assessed using the Newcastle Ottawa Scale. RESULTS: Six studies met the inclusion criteria and included a total of 663 patients. A total of twenty two aetiologies were identified. Only three studies reviewed non surgical aetiologies. Many of the studies relied on medical imaging to identify the aetiologies. A meta-analysis was not undertaken due to the heterogeneity of studies. CONCLUSIONS: The causes of FBSS can be attributed to patho-anatomical, peripheral pain generators, physical/ mechanical, neurophysiological, surgical and 'other' aetiologies. Three of the studies only examined surgical causes of FBSS. Further research, that examines surgical and non-surgical aetiologies, is required to draw firm conclusions. With nineteen aetiologies identified, FBSS remains an unclear diagnosis for a complex heterogeneous group of patients. PMID- 27689602 TI - The clinical factors associated with benefit finding of complementary medicine use in patients with back pain: A cross-sectional study with cluster analysis. AB - BACKGROUND: Complementary and alternative medicine (CAM) use has been increasing. OBJECTIVE: To identify the factors associated with perceived benefit from CAM methods in back problems. METHODS: The study was conducted on patients who practiced any CAM methods due to complaints of back pain. Social-demographic properties, details of CAM methods employed were questioned. Severity of pain was measured by visual analog scale (VAS); benefits were evaluated by the Likert scale. Hierarchical cluster analysis was used to discover relationships among variables. RESULTS: In total, 500 patients (265 female, 235 male) were included in the study. Mostly used methods were herbal therapy (32%), balneotherapy (31%), cupping (19.4%) and massage-manipulation (19.2%). Of patients, 355 (71%) were satisfied. The variables associated with benefit finding were female gender, age, chronicity and severity of pain, high educational level, upper middle income status, use as a result of recommendation, dissatisfaction with conventional methods, residence in an urban area, non-herbal method use, being married, and social insurance (p < 0.005). CONCLUSION: The majority of patients using CAM perceived benefits; in particular, women living in urban areas, highly educated, aged more than 40, who suffer from severe chronic back pain, may be more inclined to go to CAM therapists. PMID- 27689603 TI - Association of low back pain on physical, sociodemographic and lifestyle factors across a general population sample within Greece. AB - BACKGROUND: Although low back pain (LBP) is a debilitating problem internationally, there is not a lot of research on its impact on physical, psychosocial and lifestyle factors. Especially in mediterranean countries, such as Greece, it is not sufficiently explored whether physical (pain location, activity limitation etc.), sociodemographic (education, smoking etc.) or lifestyle factors (i.e. quality of life or anxiety) are influenced by LBP. OBJECTIVE: To estimate LBP prevalence in the Greek general population and explore its association with particular sociodemographic, physical and lifestyle factors. METHOD: A sample of 3125 people of the Greek adult population was randomly selected by stratified sampling encompassing rural and urban representation within the Greek mainland. An extended survey form was developed entailing three sections; personal (sociodemographic) information, questions on symptomatology and physical factors (i.e. pain characteristics, recurrence, physical disability etc.) and 3 self-administered questionnaires (including mostly lifestyle factors); Hospital Anxiety and Depression (HAD) scale for anxiety and depression, SF-12 for quality of life (QoL) and Roland-Morris for disability. RESULTS: A total of 471 (15%) people reported LBP (210 males, mean age: 47.04 +/- 15.03). Amongst them 60% reported sciatica, 76% suffered recurrent LBP and 70% received specialist care. Low disability levels, moderate to high pain intensity, gender differences and good self-reported QoL and psychosocial status were reported. Sociodemographic characteristics (income, smoking, marital status etc.) were not associated with LBP physical factors, apart from age which correlated with physical disability and wellness (r being 0.446 and 0.405, respectively, p< 0.001). Physical factors (particularly pain intensity and location) correlated with lifestyle factors (QoL) and disability (r ranging between 0.396 and 0.543, p< 0.001). Mental wellness, anxiety and depression (as lifestyle factors) were not associated with sociodemographic or physical factors. CONCLUSIONS: Physical parameters were amongst the most prevalent characteristics of the Greek sample, thus offering a direction towards a more targeted treatment and rehabilitation planning. Unlike previous literature, most sociodemographic characteristics were not correlated with any LBP physical or lifestyle factors, thus possibly indicating a different socioeconomic background and aetiology domain to that of the usual non-specific LBP spectrum. PMID- 27689604 TI - Hip abductor, trunk extensor and ankle plantar flexor endurance in females with and without patellofemoral pain. AB - BACKGROUND: Previous studies have reported strength deficit in hip abduction, extension and external rotation in females with patellofemoral pain (PFP) when compared with healthy control; however, there is conflicting evidence for a decrease in hip muscle endurance. Therefore, it seems important to evaluate hip muscle endurance in females with PFP. Moreover, trunk extensor and ankle plantar flexor endurance have not yet been evaluate in females with PFP. OBJECTIVE: To compare hip abductor, trunk extensor and ankle plantar flexor endurance between females with and without PFP. METHODS: Twenty females with PFP (mean age, 21.1 years) and 76 healthy females (mean age, 20.5 years) were recruited. Subject performed three endurance clinical tests: (1) The hip abductor isometric endurance test, (2) The Sorensen test and (3) The heel rise test. Group differences were assessed using an independent t tests, or Mann-Whitney U tests for non-normally distributed data. RESULTS: Subjects with PFP exhibited significantly lower hip abductor, trunk extensor and ankle plantar flexor endurance than healthy controls. On average, subjects with PFP had deficits of 16% in hip abduction, 14% in trunk extension and 26% in ankle plantar flexion. CONCLUSION: Females with PFP exhibited diminished hip abductor, trunk extensor and ankle plantar flexor endurance compared to healthy controls. PMID- 27689605 TI - From Theory to Practice: Engagement in Neurorehabilitation. PMID- 27689606 TI - Patient centered care: A path to better health outcomes through engagement and activation. AB - BACKGROUND: Patient Activation and Health confidence are constructs to assess patient engagement and are utilized to encourage patient engagement. A health care provider may increase patient engagement further by utilizing behavior change theories and models such as the Trans-Theoretical Model of Change (TTM), Self-Determination Theory (SDT) and Motivational Interviewing (MI) to realize effective and lasting health behavior change by placing accountability increasingly on the patient/caregiver to choose to make changes in their health behavior on their terms. Reducing or eliminating harmful behaviors such as smoking and/or beginning or increasing beneficial health behaviors such as diet modification or performance of an exercise program, patients realize improved outcomes and better health. PURPOSE: The purpose of this article is to define health confidence as a measurement tool for patient engagement, use the TTM as a measure of the patient's readiness to change, use TTM, SDT and MI as interventional approaches to effect patient change of behavior encouraged by physical therapists and incorporate the ICF as a means of identifying barriers and facilitators and incorporate the bio-psychosocial model for patient-centered care to improve health behavior, health and patient outcomes. CONCLUSION: Patient centered care requires involvement of the patient and/or their caregiver at the center of the plan. Use of the International Classification of Functioning, Disability and Health (ICF) to identify facilitators and barriers unique to the patient/caregiver offers another opportunity to successfully engage the patient by incorporating the patient's bio-psychosocial support system into care delivery and for sustainability. The ICF is a taxonomy and classification system that prompts clinicians to identify environmental factors (facilitators and barriers) that will influence the patient's ability to perform during therapy session and to sustain the interventions and employ suggestions outside of formal therapy sessions. Using the facilitators to encourage sustainable change and removing barriers, patients are more likely to realize positive health behavior change and in turn demonstrate improved outcomes and health as a result of physical therapy intervention. PMID- 27689607 TI - Building Bridges between healthcare professionals, patients and families: A coproduced and integrated approach to self-management support in stroke. AB - BACKGROUND: Programmes providing self-management support for patients and families are gaining attention and have shown promising outcomes with regards to reducing long-term unmet needs post stroke. However, notions of what good self management support looks like can differ depending on professional opinion, individual preferences, skills and experiences of patients and their families as well as on how care and rehabilitation is organised in a particular healthcare setting. This resonates with the perspective of patient-centred care, according to which the meaning of good care is not universal, but rather jointly shaped between healthcare professionals and patients in everyday interactions. While self-management support is continuously co-produced in care and rehabilitation practices, most self-management programmes are typically provided as an 'add-on' to existing statutory care. OBJECTIVE: This paper aims to deepen the understanding of how self-management support can be made an integral part of everyday care and rehabilitation using Bridges methodology. METHODS: The authors provide a self-reflective account on 'Bridges' an integrated approach to self management support, which is used by healthcare professionals within acute and community stroke rehabilitation across the UK, and in some parts of New Zealand and Australia. RESULTS: Bridges is based on self-efficacy principles, but has a central aim of professionals sharing decision-making and expertise with patients and families in every healthcare interaction. Methodologically, the co-production of a Bridges support package with local healthcare professionals and patients is critical. The authors present the values articulated by the support package and how it engages professionals, patients and Bridges training facilitators in a continuous process of adjusting and re-adjusting situated self-management support practices. CONCLUSIONS: Our reflections reveal the need to consider development and implementation of self-management support as one and the same on-going process, if we are to facilitate successful engagement and interest from healthcare professionals as well as their patients and families. PMID- 27689609 TI - Engagement in social media environments for individuals with who use augmentative and alternative communication. AB - BACKGROUND: Communicative interactions, despite the mode (e.g., face-to-face, online) rely on the communication skills of each individual participating. Some individuals have significant speech and language impairments and require the use of augmentative and alternative communication (AAC) (i.e., signs, speech generating devices) to maximize their communication participation across a variety of on and offline contexts. Use of social media has brought about changes to communication environments, contributing new contexts for engagement. OBJECTIVES: To provide a framework for considering application of engagement theory for interventions around social media use by individuals who use AAC. METHODS: The author has applied examples from qualitative social media and AAC research to a framework of engagement. No formal data collection was used. RESULTS: Social media use has become a conventional form of communication. Yet recognition of the value of social media (and other electronic modalities) for individuals who use AAC has not been fully translated into practice. The examples used illustrated how the proposed framework can assist in clinical practice and future research directions. CONCLUSION: Engagement, including the proposed framework for considerations of social media engagement activities, can provide a systematic way to approach social media use for individuals who use AAC. PMID- 27689608 TI - Enhanced Medical Rehabilitation: Effectiveness of a clinical training model. AB - BACKGROUND: Patient engagement in medical rehabilitation can be greatly influenced by their provider during therapy sessions. We developed Enhanced Medical Rehabilitation (EMR), a set of provider skills grounded in theories of behavior change. EMR utilizes 18 motivational techniques focused on providing frequent feedback to patients on their effort and progress and linking these to patient goals. OBJECTIVE: To examine the effectiveness of a clinical training protocol for clinicians to do EMR, as measured by clinician adherence. METHODS: A physical therapist, physical therapist assistant, occupational therapist, and certified occupational therapist assistant were trained in EMR. Training consisted of five formal training sessions and individual and group coaching. Adherence to EMR techniques was measured during two phases: Pre-Training and Maintenance, with an a priori target of 90% adherence by clinicians to each EMR technique. RESULTS: With training and coaching, clinician adherence per therapeutic activity significantly improved in 13 out of 18 items (p < 0.05). The target of 90% adherence was not achieved for many items. CONCLUSIONS: Our training and coaching program successfully trained clinicians to promote patient engagement during therapeutic service delivery, although not typically to 90% or greater adherence. Ongoing coaching efforts were necessary to increase adherence. PMID- 27689610 TI - What influences acceptability and engagement with a high intensity exercise programme for people with stroke? A qualitative descriptive study. AB - BACKGROUND: Intensity refers to the amount of effort or rate of work undertaken during exercise. People receiving rehabilitation after stroke frequently do not reach the moderate to high intensity exercise recommended to maximise gains. OBJECTIVE: To explore the factors that influence the acceptability of, and engagement with, a high intensity group-based exercise programme for people with stroke. METHODS: This qualitative descriptive study included 14 people with stroke who had completed a 12-week, high intensity group-based exercise rehabilitation programme. Semi-structured interviews were used to explore the acceptability of high intensity exercise and the barriers and facilitators to engagement. Interviews were recorded, transcribed and analysed using qualitative content analysis. RESULTS: The participants found high intensity exercise rehabilitation acceptable despite describing the exercise intensity as hard and reporting post-exercise fatigue. Participants accepted the fatigue as a normal response to exercise, and it did not appear to negatively influence engagement. The ease with which an individual engaged in high intensity exercise rehabilitation appeared to be mediated by inter-related factors, including: seeing progress, sourcing motivation, working hard, the people involved and the fit with the person and their life. Participants directly related the intensity of their effort to the gains that they made. CONCLUSIONS: In this study, people with stroke viewed training at higher intensities as a facilitator, not a barrier, to engagement in exercise rehabilitation. The findings may challenge assumptions about the influence of exercise intensity on engagement. PMID- 27689611 TI - A fine balance and a shared learning journey: Exploring healthcare engagement through the experiences of youth with Neuromuscular Disorders. AB - BACKGROUND: Youth with Neuromuscular Disorders (NMD) who are wheelchair users can now survive well into adulthood if their multisystem comorbidities are prudently managed. Uptake of health behaviors may optimize their health outcomes. OBJECTIVE: To explore youths' perceptions of health, health behaviors and healthcare engagement. METHODS: This qualitative study purposefully recruited 11 youth with NMD from a concurrent, population-based study for variability of age, gender, type of NMD and their ratings of motivation and engagement. Interview data were analyzed and synthesized by thematic content. RESULTS: Participants perceived healthcare engagement as being given tools (knowledge and responsibility) and using them to maintain their finely balanced health. Nested in adequate social, emotional and physical support, they took responsibility for creatively integrating health behaviors they felt were informed by credible knowledge, gained primarily through personal experience. CONCLUSION: Cognizant of their compromised health, youth with NMD in this study were motivated to maintain their physical health. Limited NMD condition specific knowledge challenged youths' uptake of health behaviors. They valued a learning partnership with their healthcare professionals. By embracing the youth's experience based knowledge and through facilitating supportive relationships, healthcare professionals co construct youth's healthcare engagement that may optimize health behaviors and outcomes.

PMID- 27689612 TI - Pain, cognition and quality of life associate with structural measures of brain volume loss in multiple sclerosis. AB - BACKGROUND: Multiple sclerosis (MS) is characterized by physical and mental impairments that often result in pain and reduced quality of life. OBJECTIVE: To understand the relationship of pain, quality of life, and cognition to structural measures of brain volume. METHODS: Behavioral measures were assessed in a single session using standardized questionnaires and rating scales. Brain volume measures were assessed with structural magnetic resonance imaging (MRI). RESULTS: Twenty-nine individuals with relapsing-remitting MS and 29 age-matched controls participated in this study. Pain, quality of life, and cognition were significantly interrelated. Higher fluid attenuation inversion recovery weighted lesion volume was significantly associated with increased reports of pain (p = 0.01), lower physical quality of life (p < 0.0001), and lower cognitive performance (p = 0.001) in our cohort. CONCLUSIONS: Assessment of pain and quality of life along with structural MRI highlights the importance of understanding structure-function relationships in MS and suggests that therapists should not only evaluate individuals for cognition and quality of life, but should consider rehabilitation goals that target these areas. PMID- 27689613 TI - Increased expression ratio of matrix metalloproteinase-9 (MMP9) and tissue inhibitor of matrix metalloproteinase (TIMP-1) RNA levels in Iranian multiple sclerosis patients. AB - OBJECTIVES: Multiple sclerosis (MS) is an autoimmune disease involving the central nervous system (CNS) with unknown immunopathogenic mechanisms. Matrix metalloproteinase-9 (MMP-9) facilitates T-cell migration into the CNS while the tissue inhibitor matrix metalloproteinase-1 (TIMP-1) inhibits MMP-9 actions. The aim of this study was to evaluate the expression of TIMP-1 RNA and MMP-9/TIMP-1 RNA ratio in blood cells of Iranian patients with relapsing-remitting multiple sclerosis (RRMS) treated with IFNb. MATERIAL AND METHODS: The study compared the expression level of TIMP-1 gene in RRMS samples with normal individuals in Iran and the results were compared using a ratio of MMP-9 to TIMP-1. All patients were HLA-DRB1*15 negative and were responders to interferon-beta with a normal vitamin D level. RESULTS: The RRMS patients manifested a lower expression level of TIMP-1 RNA than their normal counterparts although the result was not significant (P= 0.06). Also, the ratio of MMP-9 to TIMP-1 RNA increased significantly (P= 0.009). There was no linear correlation between TIMP-1 expression level and risk of Expanded Disability Status Scale of Kurtzke (EDSS); nor was there any significant correlation between expression status of TIMP-1 and duration of the disease. Although there was no significant decrease in TIMP-1 expression level, the MMP 9/TIMP-1 RNA ratio in RRMS was significantly higher than normal subjects. CONCLUSION: Further studies are recommended to compare MMP-9/TIMP-1 RNA ratio in patients before and after taking IFN-beta in order to find out if MMP-9/TIMP-1 RNA ratio can function as a proper marker of the bio efficacy of IFN-beta treatment of MS. PMID- 27689615 TI - High apelin levels could be used as a diagnostic marker in multiple myeloma: A comparative study. AB - BACKGROUND: Apelin/APJ system regulates angiogenesis and is overexpressed in some malignancies. Apelin can induce lymphangiogenesis and lymph node metastasis. OBJECTIVE: We evaluated apelin levels in multiple myeloma (MM) and non-Hodgkin lymphoma (NHL); and analyzed the association between apelin levels and clinical findings. METHODS: We included consecutive 29 MM, 31 NHL patients, and 19 healthy controls. Patients' demographic and clinical features, treatment modalities, and responses were recorded from hospital records. Plasma apelin was determined by enzyme-linked immunosorbent assay (ELISA). RESULTS: MM patients had significantly higher plasma apelin level than NHL and healthy control groups (p< 0.001). Apelin level in NHL group was similar to controls (p> 0.05). ROC curve analysis showed that the area under the curve value for apelin level in MM was 0.842 ng/ml (95%CI: 0.739-0.945, p< 0.001). Plasma apelin level >= 0.827 ng/ml had 76% sensitivity and 86% specificity for the diagnosis of MM. Multivariate Cox regression analysis showed that MM patients with high apelin level had better prognosis and patients with advanced stage of disease (ISS-3) had significantly poor prognosis when compared to others. In the MM group, apelin level correlated negatively with LDH (r = -0.39, p= 0.038). CONCLUSIONS: In MM, plasma apelin level was significantly higher than in NHL and control groups. Apelin could be playing a role in MM pathogenesis; and apelin level could be used as a diagnostic and prognostic biomarker in MM. PMID- 27689616 TI - Glypican-3 and KRT19 are markers associating with metastasis and poor prognosis of pancreatic ductal adenocarcinoma. AB - OBJECTIVE: Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant tumor with metastasis in most patients at diagnosis. The molecular mechanisms associated with its high malignancy have not been fully elucidated. This study investigated the clinicopathological significances of GPC3 and KRT19 expression in PDAC. METHODS: GPC3, KRT19, and CA19-9 protein expression were measured by immunohistochemistry. RESULTS: GPC3 and KRT19 protein levels were overexpressed in PDAC tumors compared to normal pancreatic tissues, benign pancreatic tissues, and peritumoral tissues (P< 0.01). The percentage of positive GPC3 and KRT19 expression were significantly higher in PDAC patients with larger tumor size, poorly differentiated tumor, lymph node metastasis, invasion, and TNM stage III/IV disease than in patients with small tumor size, well-differentiated tumor, no lymph node metastasis and invasion, as well as TNM stage I/II stage disease (P< 0.05 or P< 0.01). Benign pancreatic lesions with positive GPC3 and KRT19 protein expression exhibited dysplasia or intraepithelial neoplasia. Kaplan-Meier survival analysis showed that PDAC patients with positive GPC3 and KRT19 expression survived significantly shorter than patients with negative GPC3 and KRT19 expression (P < 0.05 or P< 0.001). Cox multivariate analysis revealed that positive GPC3 and KRT19 expression were independent poor prognosis factors in PDAC patients. CONCLUSIONS: GPC3 and KRT19 overexpression are associated with carcinogenesis, progression, and poor prognosis in patients with PDAC and a valuable biomarker for diagnosis of PDAC. PMID- 27689617 TI - Clinical Complexity and Use of Antipsychotics and Restraints in Long-Term Care Residents with Parkinson's Disease. AB - BACKGROUND: Patients with Parkinson's disease (PD) and/or Parkinsonism are affected by a complex burden of comorbidity. Many ultimately require institutional care, where they may be subject to the application of physical restraints or the prescription of antipsychotic medications, making them more vulnerable to adverse outcomes. OBJECTIVES: The objectives of this paper are to: 1) describe the clinical complexity of older institutionalized persons with PD; and 2) examine patterns and predictors of restraint use and prescription of antipsychotics in this population. METHODS: Population-based cross-sectional cohort study. Residents with PD and/or Parkinsonism living in long-term care (LTC) facilities in 6 Canadian provinces and 1 Northern Territory and Complex Continuing Care (CCC) facilities in Manitoba and Ontario, Canada. The RAI MDS 2.0 instrument was used to assess all LTC residents and CCC residents. Clinical characteristics and the prevalence of major comorbidities were examined. Multivariate modeling was used to identify the characteristics of PD residents most associated with the prescription of antipsychotics and the use of restraints in LTC and CCC facilities. RESULTS: Residents with PD in LTC and CCC exhibit a high prevalence of dementia, major psychiatric disorders, stroke, heart failure, chronic obstructive pulmonary disease and diabetes mellitus. More than 90% of LTC and CCC residents with PD had cognitive impairment; with more than half having moderate to severe impairment. Residents with PD were more likely to receive antipsychotics than those without PD. Antipsychotic use was associated with psychosis and aggressive behaviours, but also with unsteady gait and higher comorbidity and medication count. Similarly, although more common in CCC than LTC facilities, both psychosis and aggressive behaviours were associated with restraint use, as was greater cognitive and functional impairment, and urinary incontinence. Younger age, male gender, and lower physician access were all associated with greater antipsychotic and restraint use. CONCLUSIONS: LTC and CCC residents with PD are very complex medically. Use of antipsychotics and restraints is common, and their use is often associated with factors other than psychosis or aggression. PMID- 27689618 TI - Assistive Technology for Cognition and Health-related Quality of Life in Huntington's Disease. AB - BACKGROUND: Assistive technology for cognition (ATC) can be defined as external devices aimed at supporting cognitive function. Studies in neurological populations suggest that use of ATC is a promising strategy to ameliorate negative effects of cognitive impairment and improve Health-related Quality of Life (HRQoL). There is a lack of studies on the effects of ATC in HD. OBJECTIVE: This study aimed to describe the use of ATC in patients with HD, and to investigate the association between ATC and HRQoL. METHODS: A cross-sectional population-based study, including eighty-four patients with a clinical HD diagnosis (stages I-V). Socio-demographic and clinical data were collected, including information regarding various aspects of ATC use and an evaluation of cognitive impairment was performed. The Unified Huntington's Disease Rating Scale (UHDRS) Total Functional Capacity scale (TFC) and the EQ-5D Visual Analogue Scale were used to evaluate functional ability and HRQoL. Descriptive analyses were conducted to describe ATC use and regression analyses to investigate associations between ATC and HRQoL. RESULTS: Thirty-seven percent of the patients had ATC, and ATC was used most frequently in stages I-III. Information about ATC, needs evaluation and training was provided to 44%, 32.1% and 20.2% respectively. The regression analysis showed a significant association between TFC and HRQoL (beta value = -0.564, p = 0.001), but there was no association between ATC and HRQoL. CONCLUSIONS: One-third of all patients used ATC, mainly those with mild to moderate cognitive impairment (stage I -III). No association between ATC and HRQoL was found. More research is needed to investigate effects of ATC in HD. PMID- 27689621 TI - Polymorphism in a Cobalt-Based Single-Ion Magnet Tuning Its Barrier to Magnetization Relaxation. AB - A large barrier to magnetization reversal, a signature of a good single-molecule magnet (SMM), strongly depends on the structural environment of a paramagnetic metal ion. In a crystalline state, where SMM properties are usually measured, this environment is influenced by crystal packing, which may be different for the same chemical compound, as in polymorphs. Here we show that polymorphism can dramatically change the magnetic behavior of an SMM even with a very rigid coordination geometry. For a cobalt(II) clathrochelate, it results in an increase of the effective barrier from 109 to 180 cm-1, the latter value being the largest one reported to date for cobalt-based SMMs. Our finding thus highlights the importance of identifying possible polymorphic phases in search of new, even more efficient SMMs. PMID- 27689620 TI - Cellular Analysis of Silencing the Huntington's Disease Gene Using AAV9 Mediated Delivery of Artificial Micro RNA into the Striatum of Q140/Q140 Mice. AB - BACKGROUND: The genetic mutation in Huntington's disease (HD) is a CAG repeat expansion in the coding region of the huntingtin (Htt) gene. RNAi strategies have proven effective in substantially down-regulating Htt mRNA in the striatum through delivery of siRNAs or viral vectors based on whole tissue assays, but the extent of htt mRNA lowering in individual neurons is unknown. OBJECTIVE: Here we characterize the effect of an AAV9-GFP-miRHtt vector on Htt mRNA levels in striatal neurons of Q140/Q140 knock-in mice. METHODS: HD mice received bilateral striatal injections of AAV9-GFP-miRHtt or AAV9-GFP at 6 or 12 weeks and striata were evaluated at 6 months of age for levels of Htt mRNA and protein and for mRNA signal within striatal neurons using RNAscope multiplex fluorescence in situ hybridization. RESULTS: Compared to controls, the striatum of 6-month old mice treated at 6 or 12 weeks of age with AAV9-GFP-miRHtt showed a reduction of 40-50% in Htt mRNA and lowering of 25-40% in protein levels. The number of Htt mRNA foci in medium spiny neurons (MSNs) of untreated Q140/Q140 mice varied widely per cell (0 to 34 per cell), with ~10% of MSNs devoid of foci. AAV9-GFP-miRHtt treatment shifted the distribution toward lower numbers and the percentage of cells without foci increased to 14-20%. The average number of Htt mRNA foci per MSN was reduced by 43%. CONCLUSIONS: The findings here show that intrastriatal infusion of an AAV9-GFP-miRHtt vector lowers mRNA expression of Htt in striatum by ~50%, through a partial reduction in the number of copies of mutant Htt mRNAs per cell. These findings demonstrate at the neuronal level the variable levels of Htt mRNA expression in MSNs and the neuronal heterogeneity of RNAi dependent Htt mRNA knockdown. PMID- 27689619 TI - Autophagy Activation by Transcription Factor EB (TFEB) in Striatum of HDQ175/Q7 Mice. AB - BACKGROUND: Mutant huntingtin (mHTT) is encoded by the Huntington's disease (HD) gene and its accumulation in the brain contributes to HD pathogenesis. Reducing mHTT levels through activation of the autophagosome-lysosomal pathway may have therapeutic benefit. Transcription factor EB (TFEB) regulates lysosome biogenesis and autophagy. OBJECTIVE: To examine if increasing TFEB protein levels in HD mouse striatum induces autophagy and influences mHTT levels. METHODS: We introduced cDNA encoding TFEB with an HA tag (TFEB-HA) under the control of neuron specific synapsin 1 promoter into the striatum of 3 month old HDQ175/Q7 mice using adeno-associated virus AAV2/9. The levels of exogenous TFEB were analyzed using qPCR and Western blot. Proteins involved in autophagy, levels of huntingtin, and striatal-enriched proteins were examined using biochemical and/or immunohistochemical methods. RESULTS: In HD mice expressing TFEB-HA, HA immunoreactivity distributed throughout the striatum in neuronal cell bodies and processes and preferentially in neuronal nuclei and overlapped with a loss of DARPP32 immunoreactivity. TFEB-HA mRNA and protein were detected in striatal lysates. There were increased levels of proteins involved with autophagosome/lysosome activity including LAMP-2A, LC3II, and cathepsin D and reduced levels of mutant HTT and the striatal enriched proteins DARPP32 and PDE10A. Compared to WT mice, HDQ175/Q7 mice had elevated levels of the ER stress protein GRP78/BiP and with TFEB-HA expression, increased levels of the astrocyte marker GFAP and pro-caspase 3. CONCLUSION: These results suggest that TFEB expression in the striatum of HDQ175/Q7 mice stimulates autophagy and lysosome activity, and lowers mHTT, but may also increase a neuronal stress response.

AB - Lung-targeting sophoridine-loaded poly(lactide-co-glycolide) (PLGA) microspheres were constructed by a simple oil-in-oil emulsion-solvent evaporation method. The obtained microspheres were systematically studied on their morphology, size distribution, drug loading, encapsulation efficiency, in vitro release profile, and biodistribution in rats. The drug-loaded microparticles showed as tiny spheres under SEM and had an average size of 17 MUm with 90% of the microspheres ranging from 12 to 24 MUm. The drug loading and encapsulation efficiency were 65% and 6.5%, respectively. The in vitro drug release behavior of microspheres exhibited an initial burst of 16.6% at 4 h and a sustained-release period of 14 days. Drug concentration in lung tissue of rats was 220.10 MUg/g for microspheres and 6.77 MUg/g for solution after intraveneous injection for 30 min, respectively. And the microsphere formulation showed a significantly higher drug level in lung tissue than in other major organs and blood samples for 12 days. These results demonstrated that the obtained PLGA microspheres could potentially improve the treatment efficacy of sophoridine against lung cancer. PMID- 27689623 TI - Alarmins and Clinical Outcomes After Major Abdominal Surgery-A Prospective Study. AB - PURPOSE: Tissue injury causing immune response is an integral part of surgical procedure. Evaluation of the degree of surgical trauma could help to improve postoperative management and determine the clinical outcomes. MATERIALS AND METHODS: We analyzed serum levels of alarmins, including S100A5, S100A6, S100A8, S100A9, S100A11, and S100A12; high-mobility group box 1; and heat-shock protein 70, after elective major abdominal surgery (n = 82). Blood samples were collected for three consecutive days after surgery. The goals were to evaluate the relationships among the serum levels of alarmins and selected surgical characteristics and to test potential of alarmins to predict the clinical outcomes. RESULTS: Significant, positive correlations were found for high mobility group box 1 with the length of surgery, blood loss, and intraoperative fluid intake for all three days of blood sampling. The protein S100A8 serum levels showed positive correlations with intensive care unit length of stay, 28 day and in-hospital mortality. The protein S100A12 serum levels had significant, positive correlations with intensive care unit length of stay, 28-day mortality, and in-hospital mortality. We did not find significant differences in alarmin levels between cancer and noncancer subjects. CONCLUSION: The high-mobility group box 1 serum levels reflect the degree of surgical injury, whereas proteins S100A8 and S100A12 might be considered good predictors of major abdominal surgery morbidity and mortality. PMID- 27689624 TI - Subcellular proteomics analysis of different stages of colorectal cancer cell lines. AB - Studying cell differentiation and transformation allows a better understanding of the mechanisms involved in the initiation and the evolution of cancer. The role of proteins which participate in these processes is dependent on their location within the cell. Determining the subcellular localization of proteins or the changes in localization is, therefore, paramount in elucidating their role. Using quantitative mass spectrometry, we characterized the protein expression and subcellular localization of nearly 5000 proteins from seven different colorectal cancer (CRC) cell lines, as well as normal colon fibroblasts and intestinal epithelial cells. This cellular characterization allowed the identification of colon cancer-associated proteins with differential expression patterns as well as deregulated protein networks and pathways. Indeed, our results demonstrate differential expression of proteins involved in cell adhesion, cytoskeleton, and transcription in colon cancer cells compared to normal colon-derived cells. Pathway analyses identified different cellular functions, including endocytosis and eIF2 signaling, whose deregulation correlates with mutations found in the different CRC phenotypes. Our results provide an unbiased, quantitative and high throughput approach to measure changes in protein expression and subcellular protein locations in different CRC cell lines. PMID- 27689625 TI - The positive net radiative greenhouse gas forcing of increasing methane emissions from a thawing boreal forest-wetland landscape. AB - At the southern margin of permafrost in North America, climate change causes widespread permafrost thaw. In boreal lowlands, thawing forested permafrost peat plateaus ('forest') lead to expansion of permafrost-free wetlands ('wetland'). Expanding wetland area with saturated and warmer organic soils is expected to increase landscape methane (CH4 ) emissions. Here, we quantify the thaw-induced increase in CH4 emissions for a boreal forest-wetland landscape in the southern Taiga Plains, Canada, and evaluate its impact on net radiative forcing relative to potential long-term net carbon dioxide (CO2 ) exchange. Using nested wetland and landscape eddy covariance net CH4 flux measurements in combination with flux footprint modeling, we find that landscape CH4 emissions increase with increasing wetland-to-forest ratio. Landscape CH4 emissions are most sensitive to this ratio during peak emission periods, when wetland soils are up to 10 degrees C warmer than forest soils. The cumulative growing season (May-October) wetland CH4 emission of ~13 g CH4 m-2 is the dominating contribution to the landscape CH4 emission of ~7 g CH4 m-2 . In contrast, forest contributions to landscape CH4 emissions appear to be negligible. The rapid wetland expansion of 0.26 +/- 0.05% yr-1 in this region causes an estimated growing season increase of 0.034 +/- 0.007 g CH4 m-2 yr-1 in landscape CH4 emissions. A long-term net CO2 uptake of >200 g CO2 m-2 yr-1 is required to offset the positive radiative forcing of increasing CH4 emissions until the end of the 21st century as indicated by an atmospheric CH4 and CO2 concentration model. However, long-term apparent carbon accumulation rates in similar boreal forest-wetland landscapes and eddy covariance landscape net CO2 flux measurements suggest a long-term net CO2 uptake between 49 and 157 g CO2 m-2 yr-1 . Thus, thaw-induced CH4 emission increases likely exert a positive net radiative greenhouse gas forcing through the 21st century. PMID- 27689626 TI - Distinct protein and mRNA kinetics of skeletal muscle proton transporters following exercise can influence interpretation of adaptations to training. AB - NEW FINDINGS: What is the central question of this study? Following a training intervention, how is the interpretation of adaptations in skeletal muscle H+ transporters influenced by biopsy timing in the context of individual protein and mRNA kinetics after the final exercise bout? What is the main finding and its importance? We show that distinct postexercise protein and mRNA kinetics for monocarboxylate transporter 1/4 and sodium-hydrogen exchanger 1 indicate that timing of a single end-point biopsy after a training intervention can influence the inferences made. Furthermore, we found the intrasubject, intersample variability of the muscle buffer capacity titration assay to be greater than the typical training effect. In order to gain a better understanding of training induced adaptations in skeletal muscle pH regulation, in this study we measured protein and mRNA kinetics of proton (H+ ) transporters for 72 h following a bout of high-intensity interval exercise (HIIE), conducted after 4 weeks of similar training. We also assayed muscle buffer capacity (betam) by a titration technique (betamin vitro ) over the same period. Sixteen active men cycled for seven bouts of 2 min at ~80% of peak aerobic power, interspersed with 1 min rest. Compared with the first 9 h postexercise, monocarboxylate transporter (MCT) 1 protein content was ~1.3-fold greater 24-72 h post-HIIE, whereas there was no such change in MCT4 protein content. Conversely, MCT1 and MCT4 mRNA expression progressively decreased 9-72 h post-HIIE. Sodium-hydrogen exchanger 1 (NHE1) protein content was lower 9 h post-HIIE (~0.8-fold) compared with every other postexercise time point, but NHE1 mRNA expression was 2.2 to 2.9-fold greater 24-72 h post-HIIE, compared with the first 24 h post-HIIE. Furthermore, we determined the intrasubject, intersample variability (11.5%) of betamin vitro for resting samples taken on consecutive days to be greater than the typical training effect (mean 6%; 95% confidence limits +/-4%). In conclusion, the delay in steady-state protein turnover should inform biopsy timing in studies investigating the response to training of the H+ transport proteins, whereas the temporal resolution provided by single time points has been shown to be of limited epistemological value for their corresponding mRNA expression. Finally, our data cast doubt on the ecological validity of the betamin vitro assay for measuring true changes in betam. PMID- 27689628 TI - Why nurses leave. AB - 'I left because I was utterly exhausted. I was frustrated because I couldn't do the job properly, I wasn't nursing, I was trying to survive each shift. When I asked for help nobody was interested; not being able to cope was seen as my personal failure. When I offered advice no-one listened; management simply didn't care about me, my views, or the care we were giving to patients.' These comments came from a nurse who, after six years as a sister in an acute medical ward, left nursing to join a large pharmaceutical company. Now she feels part of a team, valued by management and encouraged to take part in continuing education to meet new demands and responsibilities. PMID- 27689629 TI - ?

PMID- 27689627 TI - Incidence Rate of Prediabetes Progression to Diabetes: Modeling an Optimum Target Group for Intervention. AB - Thirty-seven percent of US adults have prediabetes. Various interventions can delay diabetes progression; however, the optimum target group for risk reduction is uncertain. This study estimated rate of progression to diabetes at 1 and 5 years among a cohort of patients from 3 primary care clinics and modeled the potential magnitude in diabetes incidence risk reduction of an intervention program among specific subgroups. Records of 106,821 empaneled patients in 2005 were reviewed. Generalized population attributable risk (PAR) statistics were calculated to estimate the impact of reducing fasting blood glucose on diabetes progression. Multiple intervention effects (varying levels of glucose reduction along with multiple adherence rates) were examined for those with baseline glucose from 110 to 119 mg/dL and >=120 mg/dL. Ten percent of patients (n = 10,796) met criteria for prediabetes. The 1- and 5-year diabetes incidence rate was 38.6 and 40.24 per 1000 person-years, respectively. Age and obesity were independent predictors of increased progression rate. The generalized PAR for a 10-point reduction in the 110-119 mg/dL subgroup with 25% adherence was 7.6%. The generalized PAR for similar percent reduction and adherence level in patients with baseline glucose of >=120 mg/dL was only 3.0%. Rate of progression to diabetes increased over time and with associated independent risk factors. Greater risk reduction in diabetes progression within the target population can be achieved when the intervention is successful in those with baseline glucose of 110-119 mg/dL. Modeling an optimum target group for a diabetes prevention intervention offers a novel and useful guide to planning and allocating resources in population health management.

PMID- 27689675 TI - Fall Risk Assessment Predicts Fall-Related Injury, Hip Fracture, and Head Injury in Older Adults. AB - OBJECTIVES: To investigate the role of a fall risk assessment, using the Downton Fall Risk Index (DFRI), in predicting fall-related injury, fall-related head injury and hip fracture, and death, in a large cohort of older women and men residing in Sweden. DESIGN: Cross sectional observational study. SETTING: Sweden. PARTICIPANTS: Older adults (mean age 82.4 +/- 7.8) who had a fall risk assessment using the DFRI at baseline (N = 128,596). MEASUREMENTS: Information on all fall related injuries, all fall-related head injuries and hip fractures, and all-cause mortality was collected from the Swedish Patient Register and Cause of Death Register. The predictive role of DFRI was calculated using Poisson regression models with age, sex, height, weight, and comorbidities as covariates, taking time to outcome or end of study into account. RESULTS: During a median follow-up of 253 days (interquartile range 90-402 days) (>80,000 patient-years), 15,299 participants had a fall-related injury, 2,864 a head injury, and 2,557 a hip fracture, and 23,307 died. High fall risk (DFRI >=3) independently predicted fall related injury (hazard ratio (HR) = 1.43, 95% confidence interval (CI) = 1.39 1.49), hip fracture (HR = 1.51, 95% CI =1.38-1.66), head injury (HR = 1.12, 95% CI = 1.03-1.22), and all-cause mortality (HR = 1.39, 95% CI = 1.35-1.43). DFRI more strongly predicted head injury (HR = 1.29, 95% CI = 1.21-1.36 vs HR = 1.08, 95% CI = 1.04-1.11) and hip fracture (HR = 1.41, 95% CI = 1.30-1.53 vs HR = 1.08, 95% CI = 1.05-1.11) in 70-year old men than in 90-year old women (P < .001). CONCLUSION: Fall risk assessment using DFRI independently predicts fall-related injury, fall-related head injury and hip fracture, and all-cause mortality in older men and women, indicating its clinical usefulness to identify individuals who would benefit from interventions. PMID- 27689677 TI - Highly Transparent Conducting Nanopaper for Solid State Foldable Electrochromic Devices. AB - It is of great challenge to develop a transparent solid state electrochromic device which is foldable at the device level. Such devices require delicate designs of every component to meet the stringent requirements for transparency, foldability, and deformation stability. Meanwhile, nanocellulose, a ubiquitous natural resource, is attracting escalating attention recently for foldable electronics due to its extreme flexibility, excellent mechanical strength, and outstanding transparency. In this article, transparent conductive nanopaper delivering the state-of-the-art electro-optical performance is achieved with a versatile nanopaper transfer method that facilitates junction fusing for high quality electrodes. The highly compliant nanopaper electrode with excellent electrode quality, foldability, and mechanical robustness suits well for the solid state electrochromic device that maintains good performance through repeated folding, which is impossible for conventional flexible electrodes. A concept of camouflage wearables is demonstrated using gloves with embedded electrochromics. The discussed strategies here for foldable electrochromics serve as a platform technology for futuristic deformable electronics. PMID- 27689678 TI - Acute calcium kinetics in haemodialysis patients. AB - INTRODUCTION: To avoid excessive calcium loading in haemodialysis (HD) patients, current guidelines suggest a dialysate calcium concentration (dCa) of 2.5 mEq/L based on relatively stable intradialytic serum calcium levels. However, the latter do not account for possible calcium storage in acutely accessible pools. A rapidly exchangeable calcium pool located at the bone level has been previously proposed to be involved in acute (minute-to-minute) extracellular calcium regulation. DESIGN: To evaluate the contribution of this pool in the maintenance of serum calcium levels, acute calcium buffer capacity was assessed by measuring intradialytic dialysate-sided ionized calcium mass balance (iCaMB ) and change in extracellular fluid calcium mass in chronic HD patients using a dCa of 3.5 (n = 28) and 2.5 (n = 10) mEq/L. Serum osteocalcin, the most abundant noncollagenous bone protein, was measured before the HD session. RESULTS: iCaMB was invariably positive for both 2.5 and 3.5 mEq/L dCa, with a mean of 434 (+/-125) and 725 (+/ 162) mg/HD, respectively (P < 0.001). Buffered intradialytic calcium load was 410 (+/-116) and 565 (+/-130) mg/HD, and acute calcium buffer capacity was 95 (+/-8)% and 78 (+/-7)% (mean values at 2.5 and 3.5 mEq/L dCa, respectively) (P < 0.001). Using 3.5 mEq/L dCa, an independent association of acute calcium buffer capacity with undercarboxylated osteocalcin (beta = 0.512, P = 0.002) was demonstrated. CONCLUSIONS: Our data strongly suggest the existence of a rapidly exchangeable calcium pool that counteracts acute serum calcium deviations in HD patients. This study provides, for the first time, experimental evidence for the involvement of bone in acute extracellular calcium regulation in vivo. PMID- 27689679 TI - A Star-shaped Oligo(phenylenevinylene) Liquid Crystal Host with an Anthracene Guest-A Double Nanosegregating Supermesogen. AB - Hexasubstituted C3 -symmetric benzenes with three elongated shape-persistent oligo(phenylenevinylene) arms and three pyridyl hydrogen-bond acceptors have been synthesized. These mesogens assemble in a double-helical columnar liquid crystal (LC) structure, owing to the compensation of free spaces between conjugated arms by dimer formation. The void is filled also by up to three anthracene carboxylic acids as guests forming hydrogen bonded supermesogens assembling in columnar LC and soft-crystal phases. Thin film fluorescence and solid-state NMR spectroscopy imply a transition from a disordered columnar LC to an unexpected double nanosegregated morphology of a filled soft columnar crystal phase. An additional intracolumnar separation of anthracene and oligo(phenylenevinylene) chromophores occurs, separate to the general segregation of aliphatic and aromatic building blocks in LC structures. The new type of supermesogens will enable the rational design of host-guest double cables with a wide range of different conjugated building blocks.

Treatment of [(thf)4 Ca(MU2 -NSiPh3 )(MU2 -Me)AlMe2 ] with phenylsilane results in H-Si addition across the Ca-N imido bond, producing a homoleptic calcium amidoaluminate complex and putative CaH2 whereas reaction with phenylacetylene leads to protonation of an AlMe moiety to yield the dimeric complex [(thf)Ca{NSiPh3 }{AlMe2 (CCPh)}]2 .

PMID- 27689682 TI - Developmental study identifies the ages at which the processes involved in the perception of verticality and in postural stability occur. AB - AIM: The aim of this study was to understand the role played by visual information on the development of verticality and postural stability in healthy children. METHODS: The study comprised 66 healthy children from 4.0 to 15.7 years of age. Postural performances were recorded with a TechnoConcept platform. At the same time, the children's perception of subjective visual vertical (SVV) was recorded while they adjusted a vertical fluorescent line, either in the dark or in the presence of perturbing visual stimuli. Two testing control conditions without an SVV task were also performed by all of the children: static posturographic recording with open eyes and closed eyes. RESULTS: Postural measurements provided evidence of a correlation between the children's age and the tasks performed. Postural stability improved with age until eight to nine years, and SVV performance improved after 10-11 years. After these ages, postural and SVV capabilities did not change until at least 15 years of age. CONCLUSION: Our findings suggest that the maturation of cortical and central processes involved in both the perception of verticality and in postural stability took place during childhood. However, maturation occurred later for vertical perception, which could imply delayed maturation of sensory integration processes. PMID- 27689683 TI - Shock wave treatment after hindlimb ischaemia results in increased perfusion and M2 macrophage presence. AB - Shock wave therapy (SWT) has been shown to induce angiogenesis in ischaemic muscle. However, the mechanism of action remains unknown. Macrophages are crucial for angiogenic responses after ischaemic injury. The M2 macrophage subset enables tissue repair and induces angiogenesis. It was hypothesized that the angiogenic effects of SWT are at least partly caused by enhanced macrophage recruitment. C57BL/6 mice were subjected to hind limb ischaemia with subsequent SWT or sham treatment. Muscles were analysed via immunofluorescence staining, reverse transcription polymerase chain reaction and western blot. Gene expression and proteins involved in macrophage recruitment were analysed and tissue sections were stained for macrophages, including subsets, capillaries and arterioles. Laser Doppler perfusion imaging was performed to assess functional outcome. Treated muscles showed increased expression of the pivotal macrophage recruiting factor monocyte chemotactic protein 1 (MCP-1). Higher levels of macrophage marker CD14 were found. Increased numbers of macrophages after SWT could be confirmed by immunofluorescence staining. The expression of the M2 polarization promoting chemokine interleukin 13 was significantly elevated in the treatment group. Elevated mRNA expression of the M2 scavenger receptor CD163 was found after SWT. Immunofluorescence staining confirmed increased numbers of M2 macrophages after treatment. It was found that SWT resulted in higher number of capillaries and arterioles. Assessment of functional outcome revealed significantly improved limb perfusion in treated animals. Shock wave therapy causes increased macrophage recruitment and enhanced polarization towards reparative M2 macrophages in ischaemic muscle resulting in angiogenesis and improved limb perfusion and therefore represents a promising new treatment option for the treatment of ischaemic heart disease.

AB - Through advances in analytical methods to detect glycoproteins and to determine glycan structures, there have been increasing reports of protein glycosylation in bacteria. In this review, we summarize the known pathways for bacterial protein glycosylation: lipid carrier-mediated 'en bloc' glycosylation; and cytoplasmic stepwise protein glycosylation. The exploitation of bacterial protein glycosylation systems, especially the 'mix and match' of three independent but similar pathways (oligosaccharyltransferase-mediated protein glycosylation, lipopolysaccharide and peptidoglycan biosynthesis) in Gram-negative bacteria for glycoengineering recombinant glycoproteins is also discussed.

AB - Ingestion of contaminated soil is one potential internal exposure pathway in areas contaminated by the Fukushima Daiichi Nuclear Power Plant accident. Doses from this pathway can be overestimated if the availability of radioactive nuclides in soils for the gastrointestinal tract is not considered. The concept of bioaccessibility has been adopted to evaluate this availability based on in vitro tests. This study evaluated the bioaccessibility of radioactive cesium from soils via the physiologically-based extraction test (PBET) and the extractability of those via an extraction test with 1 mol/L of hydrochloric acid (HCl). The bioaccessibility obtained in the PBET was 5.3% +/- 1%, and the extractability in the tests with HCl was 16% +/- 3%. The bioaccessibility was strongly correlated with the extractability. This result indicates the possibility that the extractability in HCl can be used as a good predictor of the bioaccessibility with PBET. In addition, we assessed the doses to children from the ingestion of soil via hand-to-mouth activity based on our PBET results using a probabilistic approach considering the spatial distribution of radioactive cesium in Date City in Fukushima Prefecture and the interindividual differences in the surveyed amounts of soil ingestion in Japan. The results of this assessment indicate that even if children were to routinely ingest a large amount of soil with relatively high contamination, the radiation doses from this pathway are negligible compared with doses from external exposure owing to deposited radionuclides in Fukushima Prefecture.

AB - Chitinase from the thermophilic mould Myceliopthora thermophila BJA (MtChit) is an acid tolerant, thermostable and organic solvent stable biocatalyst which does not require any metal ions for its activity. To produce high enzyme titres, reduce fermentation time and overcome the need for induction, this enzyme has been heterologously expressed under GAP promoter in the GRAS yeast, Pichia pastoris. The production medium supplemented with the permeabilizing agent Tween 20 supported two-fold higher rMtChit production (5.5 * 103 U L-1 ). The consensus sequences S(132)xG(133)G(134) and D(168)xxD(171)xD(173)xE(175) in the enzyme have been found to represent the substrate binding and catalytic sites, respectively. The rMtChit, purified to homogeneity by a two-step purification strategy, is a monomeric glycoprotein of ~48 kDa, which is optimally active at 55 degrees C and pH 5.0. The enzyme is thermostable with t1/2 values of 113 and 48 min at 65 and 75 degrees C, respectively. Kinetic parameters Km , Vmax , kcat , and kcat /Km of the enzyme are 4.655 mg mL-1 , 34.246 nmol mg-1 s-1 , 3.425 * 106 min-1 , and 1.36 * 10-6 mg mL-1 min-1 , respectively. rMtChit is an unique exochitinase, since its action on chitin liberates N-acetylglucosamine NAG. The enzyme inhibits the growth of phytopathogenic fungi like Fusarium oxysporum and Curvularia lunata, therefore, this finds application as biofungicide at high temperatures during summer in tropics.

AB - Patients with familial/heritable retinoblastoma (RB) are at increased risk of developing second malignancies throughout life, including a pineoblastoma (trilateral RB [TRB]) in early childhood. Current guidelines recommend regular surveillance brain imaging for those with heritable RB until 5 years of age. The presence of pineal cysts has been reported in patients with RB. Pineal cysts are thought to arise due to focal degeneration of the pineal gland and can be found incidentally. The finding of pineal abnormalities including cysts in children with RB on imaging is disconcerting, as it raises the possibility of an underlying malignancy, specifically a pinealoblastoma. The authors reviewed the imaging findings and clinical significance of pineal cysts in 69 patients diagnosed with RB at our center between December 1999 and November 2015. Twenty six patients had pineal cysts found on brain magnetic resonance imaging (MRI) scans performed either at diagnosis or follow-up. Thirty-eight of 69 patients had underlying heritable RB. Nineteen of 38 familial RB patients had a pineal cyst compared with 3 out of 26 with sporadic RB (P = .004). In the majority, the imaging characteristics and size of the cysts remained stable or resolved. In this cohort, pineal cysts were detected at significantly increased frequency in heritable RB. This may be a benign association or may reflect abnormal underlying biology of pineal tissue in individuals highly susceptible to malignancy. Imaging characteristics can be helpful in distinguishing between benign and malignant lesions. The presence of a pineal cyst in patients with unilateral disease may be a useful indicator of underlying heritable RB.

AB - We report on the treatment and successful outcome of a 58-year-old Native American male with a history of complex trauma presenting with dissociative identity disorder (DID) and major depressive disorder. The treatment included a trauma-informed phase-based psychotherapy as recommended by the International Society for the Study of Trauma and Dissociation for treating DID. We assessed symptoms at baseline and at three additional time points over the course of 14 months. We utilized the Reliable Change Index to examine statistically significant change in symptoms over the course of treatment. Significant symptom improvements were realized posttreatment across all measured domains of functioning, including dissociative symptoms, alcohol abuse, depression, anxiety, and emotion regulation skills. Moreover, the client no longer met criteria for DID, major depressive disorder, or alcohol abuse. Results are discussed in terms of the effectiveness of trauma-focused, phase-based treatment for DID for cases of complex trauma with comorbid disorders. PMID- 27689690 TI - The effect of cushion properties on skin temperature and humidity at the body support interface. AB - The purpose of this study is to explore the effects of various cushions on skin temperature and moisture at the body-seat interface during a 2-hour period of continuous sitting. Seventy-eight participants were randomly assigned to sit on one of the three types of wheelchair cushions for unrelieved sitting for over 2 hours. Skin temperature and relative humidity (RH) were measured under the subjects' ischial tuberosities and thighs bilaterally with digital temperature and humidity sensors. Data were collected before sitting and at 15-minute intervals thereafter. Participants sitting on foam-fluid hybrid cushions showed significantly lower skin temperatures than those sitting on air-filled and foam cushions (p < 0.05), but RH did not differ significantly among the cushions (p = 0.97). The three cushions produced a similar increasing trend in RH over time and RH reached a plateau during the 2-hour sitting period. To select the appropriate wheelchair cushion, the microclimate (heat and moisture control) between the body seat interface should be considered as well as pressure distribution. In comparison with foam-fluid hybrid cushions, the air-filled rubber and foam cushions tended to increase skin temperature by several degrees after prolonged sitting. However, cushion materials did not have significant differences in moisture accumulations. PMID- 27689688 TI - A Randomized Controlled Trial to Increase Navy Bean or Rice Bran Consumption in Colorectal Cancer Survivors. AB - Consumption of navy beans (NB) and rice bran (RB) have been shown to inhibit colon carcinogenesis. Given the overall poor diet quality in colorectal cancer (CRC) survivors and low reported intake of whole grains and legumes, practical strategies to increase consumption merit attention. This study determined feasibility of increasing NB or RB intake in CRC survivors to increase dietary fiber and examined serum inflammatory biomarkers and telomere lengths. Twenty nine subjects completed a randomized controlled trial with foods that included cooked NB powder (35 g/day), heat-stabilized RB (30 g/day), or no additional ingredient. Fasting blood, food logs, and gastrointestinal health questionnaires were collected. The amount of NB or RB consumed equated to 4-9% of subjects' daily caloric intake and no major gastrointestinal issues were reported with increased consumption. Dietary fiber amounts increased in NB and RB groups at Weeks 2 and 4 compared to baseline and to control (P <= 0.01). Telomere length correlated with age and HDL cholesterol at baseline, and with improved serum amyloid A (SAA) levels at Week 4 (P <= 0.05). This study concludes feasibility of increased dietary NB and RB consumption to levels associated with CRC chemoprevention and warrants longer-term investigations with both foods in high risk populations that include cancer prevention and control outcomes. PMID- 27689691 TI - Effect of media composition on bioavailability and toxicity of silver and silver nanoparticles in fish intestinal cells (RTgutGC). AB - To understand conditions affecting bioavailability and toxicity of citrate-coated silver nanoparticles (cit-AgNP) and dissolved silver at the luminal enterocyte interface, we exposed rainbow trout (Oncorhynchus mykiss) gut cells (RTgutGC) in media of contrasting composition: two amino acid-containing media, one of which was supplemented with proteins, as can be expected during digestion; and two protein and amino acid-free media contrasting low and high chloride content, as can be expected in the lumen of fish adapting to freshwater or seawater, respectively. Dose-response curves were generated measuring cell metabolic activity, membrane and lysosome integrity over a period of 72 hours. Then, nontoxic doses were applied and total silver accumulation, metallothionein and glutathione reductase mRNA levels were determined. The presence of proteins stabilized cit-AgNP keeping them in suspension. Conversely, in protein-free media, cit-AgNP agglomerated and settled, resulting in higher cellular accumulation of silver and toxicity. Chloride concentrations in exposure media modulated the toxicity of AgNO3 but not of cit-AgNP. Moreover, while amino acid containing media are protective against AgNO3, likely due to the formation of thiolate complexes, they are only partially protective against cit-AgNP. Viability assays indicated that lysosomes are targets of cit-AgNP, supporting the hypothesis that cit-AgNP exert toxicity intracellularly. Metallothionein, a sensor of metal bioavailability, was induced by cit-AgNP in high chloride medium but not in low chloride medium, indicating that chloride might have a role in mobilizing silver from intercellular vesicles. Overall, this study shows that AgNP bioavailability and toxicity in the intestine is linked to its luminal content. PMID- 27689692 TI - Protective effect of Schizandrin B against damage of UVB irradiated skin cells depend on inhibition of inflammatory pathways. AB - Schizandrin B is extracted from Schisandra chinensis (Turcz.) Baill. This study evaluated the photoprotective effect of Schizandrin B on oxidative stress injury of the skin caused by UVB-irradiation and the molecular mechanism of the photoprotective effect of Schizandrin B, and we firstly found that Schizandrin B could block Cox-2, IL-6 and IL-18 signal pathway to protect damage of skin cells given by UVB-irradiation. In the research, we found that Schizandrin B can attenuate the UVB-induced toxicity on keratinocytes and dermal fibroblasts in human body, and can outstandingly eliminated intracellular ROS produced by UVB irradiation. These results demonstrate that Schizandrin B can regulate the function of decreasing intracellular SOD's activity and increasing the expression level of MDA in HaCaT cells result from the guidance of UVB, and it markedly reduced the production of inflammatory factors such as Cox-2, IL-6 or IL-18, decreased the expression level of MMP-1, and interdicted degradation process of collagens in UVB-radiated cells. Therefore, skin keratinocytes can be effectively protected from UVB-radiated damage by Schizandrin B, and UVB-irradiation caused inflammatory responses can be inhibited by attenuating process of ROS generating. PMID- 27689693 TI - Observation of residues in tissues of chickens exposed to low dietary concentrations of chloramphenicol. AB - To investigate potential residues in tissues arising from naturally occurring low levels of chloramphenicol in plant material, feeding studies were conducted with chickens. A common chicken feed was prepared containing 0, 10, 50 and 200 MUg kg 1 chloramphenicol and levels were confirmed by LC-MS/MS. Four separate groups of broiler chickens, eight animals in each group, were fed all their 35-day life with this contaminated feed. They were allowed ad libitum access to this feed and fresh water. After slaughtering the chickens, the residues in muscle and liver tissues were determined using GC/MS-NCI method. No residues were detected in tissues of animals from groups fed with feed containing 0, 10 or 50 ug kg-1. Low chloramphenicol residual concentrations were observed in a few of the muscle samples obtained from the group of chickens fed with feed containing chloramphenicol in added concentration 200 ug kg-1. No residues were detected in the remaining samples of this group. These results indicate that when residues of chloramphenicol are detected it is in all probability through illegal use. PMID- 27689694 TI - Characterization of Two Monoclonal Antibodies That Recognize Linker Region and Carboxyl Terminal Domain of Coronavirus Nucleocapsid Protein. AB - The transmissible gastroenteritis virus (TGEV) nucleocapsid (N) protein plays important roles in the replication and translation of viral RNA. The present study provides the first description of two monoclonal antibodies (mAbs) (5E8 and 3D7) directed against the TGEV N protein linker region (LKR) and carboxyl terminal domain (CTD). The mAbs 5E8 and 3D7 reacted with native N protein in western blotting and immunofluorescence assay (IFA). Two linear epitopes, 189SVEQAVLAALKKLG202 and 246VTRFYGARSSSA257, located in the LKR and CTD of TGEV N protein, respectively, were identified after truncating the protein and applying a peptide scanning technique. Using mAb 5E8, we observed that the N protein was expressed in the cytoplasm during TGEV replication and that the protein could be immunoprecipitated from TGEV-infected PK-15 cells. The mAb 5E8 can be applied for different approaches to diagnosis of TGEV infection. In addition, the antibodies represent useful tools for investigating the antigenic properties of the N protein. PMID- 27689696 TI - High Resolution Mapping of Bactericidal Monoclonal Antibody Binding Epitopes on Staphylococcus aureus Antigen MntC. AB - The Staphylococcus aureus manganese transporter protein MntC is under investigation as a component of a prophylactic S.aureus vaccine. Passive immunization with monoclonal antibodies mAB 305-78-7 and mAB 305-101-8 produced using MntC was shown to significantly reduce S. aureus burden in an infant rat model of infection. Earlier interference mapping suggested that a total of 23 monoclonal antibodies generated against MntC could be subdivided into three interference groups, representing three independent immunogenic regions. In the current work binding epitopes for selected representatives of each of these interference groups (mAB 305-72-5 - group 1, mAB 305-78-7 - group 2, and mAB 305 101-8 - group 3) were mapped using Hydrogen-Deuterium Exchange Mass Spectrometry (DXMS). All of the identified epitopes are discontinuous, with binding surface formed by structural elements that are separated within the primary sequence of the protein but adjacent in the context of the three-dimensional structure. The approach was validated by co-crystallizing the Fab fragment of one of the antibodies (mAB 305-78-7) with MntC and solving the three-dimensional structure of the complex. X-ray results themselves and localization of the mAB 305-78-7 epitope were further validated using antibody binding experiments with MntC variants containing substitutions of key amino acid residues. These results provided insight into the antigenic properties of MntC and how these properties may play a role in protecting the hostagainst S. aureus infection by preventing the capture and transport of Mn2+, a key element that the pathogen uses to evade host immunity. PMID- 27689697 TI - Mtu1-Mediated Thiouridine Formation of Mitochondrial tRNAs Is Required for Mitochondrial Translation and Is Involved in Reversible Infantile Liver Injury. AB - Reversible infantile liver failure (RILF) is a unique heritable liver disease characterized by acute liver failure followed by spontaneous recovery at an early stage of life. Genetic mutations in MTU1 have been identified in RILF patients. MTU1 is a mitochondrial enzyme that catalyzes the 2-thiolation of 5-taurinomethyl 2-thiouridine (taum5s2U) found in the anticodon of a subset of mitochondrial tRNAs (mt-tRNAs). Although the genetic basis of RILF is clear, the molecular mechanism that drives the pathogenesis remains elusive. We here generated liver specific knockout of Mtu1 (Mtu1LKO) mice, which exhibited symptoms of liver injury characterized by hepatic inflammation and elevated levels of plasma lactate and AST. Mechanistically, Mtu1 deficiency resulted in a loss of 2 thiolation in mt-tRNAs, which led to a marked impairment of mitochondrial translation. Consequently, Mtu1LKO mice exhibited severe disruption of mitochondrial membrane integrity and a broad decrease in respiratory complex activities in the hepatocytes. Interestingly, mitochondrial dysfunction induced signaling pathways related to mitochondrial proliferation and the suppression of oxidative stress. The present study demonstrates that Mtu1-dependent 2-thiolation of mt-tRNA is indispensable for mitochondrial translation and that Mtu1 deficiency is a primary cause of RILF. In addition, Mtu1 deficiency is associated with multiple cytoprotective pathways that might prevent catastrophic liver failure and assist in the recovery from liver injury. PMID- 27689695 TI - Epigenetic regulation of glycosylation and the impact on chemo-resistance in breast and ovarian cancer. AB - Glycosylation is one of the most fundamental posttranslational modifications in cellular biology and has been shown to be epigenetically regulated. Understanding this process is important as epigenetic therapies such as those using DNA methyltransferase inhibitors are undergoing clinical trials for the treatment of ovarian and breast cancer. Previous work has demonstrated that altered glycosylation patterns are associated with aggressive disease in women presenting with breast and ovarian cancer. Moreover, the tumor microenvironment of hypoxia results in globally altered DNA methylation and is associated with aggressive cancer phenotypes and chemo-resistance, a feature integral to many cancers. There is sparse knowledge on the impact of these therapies on glycosylation. Moreover, little is known about the efficacy of DNA methyltransferase inhibitors in hypoxic tumors. In this review, we interrogate the impact that hypoxia and epigenetic regulation has on cancer cell glycosylation in relation to resultant tumor cell aggressiveness and chemo-resistance. PMID- 27689698 TI - Interacting Social Processes on Interconnected Networks. AB - We propose and study a model for the interplay between two different dynamical processes -one for opinion formation and the other for decision making- on two interconnected networks A and B. The opinion dynamics on network A corresponds to that of the M-model, where the state of each agent can take one of four possible values (S = -2,-1, 1, 2), describing its level of agreement on a given issue. The likelihood to become an extremist (S = +/-2) or a moderate (S = +/-1) is controlled by a reinforcement parameter r >= 0. The decision making dynamics on network B is akin to that of the Abrams-Strogatz model, where agents can be either in favor (S = +1) or against (S = -1) the issue. The probability that an agent changes its state is proportional to the fraction of neighbors that hold the opposite state raised to a power beta. Starting from a polarized case scenario in which all agents of network A hold positive orientations while all agents of network B have a negative orientation, we explore the conditions under which one of the dynamics prevails over the other, imposing its initial orientation. We find that, for a given value of beta, the two-network system reaches a consensus in the positive state (initial state of network A) when the reinforcement overcomes a crossover value r*(beta), while a negative consensus happens for r < r*(beta). In the r - beta phase space, the system displays a transition at a critical threshold betac, from a coexistence of both orientations for beta < betac to a dominance of one orientation for beta > betac. We develop an analytical mean-field approach that gives an insight into these regimes and shows that both dynamics are equivalent along the crossover line (r*, beta*).

PMID- 27689699 TI - "A Baby Was an Added Burden": Predictors and Consequences of Unintended Pregnancies for Female Sex Workers in Mombasa, Kenya: A Mixed-Methods Study. AB - INTRODUCTION: Female sex workers (FSW) have high rates of unintended pregnancy, sexually transmitted infections including HIV, and other adverse sexual and reproductive health outcomes. Few services for FSWs include contraception. This mixed-methods study aimed to determine the rate, predictors and consequences of unintended pregnancy among FSWs in Mombasa, Kenya. METHODS: A prospective cohort study of non-pregnant FSWs was conducted. Quantitative data were collected quarterly, including a structured questionnaire and testing for pregnancy and HIV. Predictors of unintended pregnancy were investigated using multivariate logistic regression. Qualitative data were gathered through focus group discussions and in-depth interviews with FSWs who became pregnant during the study, and interviews with five key informants. These data were transcribed, translated and analysed thematically. RESULTS: Four hundred women were enrolled, with 92% remaining in the cohort after one year. Fifty-seven percent reported using a modern contraceptive method (including condoms when used consistently). Over one-third (36%) of women were using condoms inconsistently without another method. Twenty-four percent had an unintended pregnancy during the study. Younger age, having an emotional partner and using traditional or no contraception, or condoms only, were independent predictors of unintended pregnancy. Women attributed pregnancy to forgetting to use contraception and being pressured not to by clients and emotional partners, as well as "bad luck". They described numerous negative consequences of unintended pregnancy. CONCLUSION: Modern contraceptive uptake is surprisingly low in this at-risk population, which in turn has a high rate of unintended pregnancy. The latter may result in financial hardship, social stigma, risk of abandonment, or dangerous abortion practices. FSWs face considerable barriers to the adoption of dual method contraceptive use, including low levels of control in their emotional and commercial relationships. Reproductive health services need to be incorporated into programs for sexually transmitted infections and HIV, which address the socially-determined barriers to contraceptive use.

AB - Systems as diverse as the interacting species in a community, alleles at a genetic locus, and companies in a market are characterized by competition (over resources, space, capital, etc) and adaptation. Neutral theory, built around the hypothesis that individual performance is independent of group membership, has found utility across the disciplines of ecology, population genetics, and economics, both because of the success of the neutral hypothesis in predicting system properties and because deviations from these predictions provide information about the underlying dynamics. However, most tests of neutrality are weak, based on static system properties such as species-abundance distributions or the number of singletons in a sample. Time-series data provide a window onto a system's dynamics, and should furnish tests of the neutral hypothesis that are more powerful to detect deviations from neutrality and more informative about to the type of competitive asymmetry that drives the deviation. Here, we present a neutrality test for time-series data. We apply this test to several microbial time-series and financial time-series and find that most of these systems are not neutral. Our test isolates the covariance structure of neutral competition, thus facilitating further exploration of the nature of asymmetry in the covariance structure of competitive systems. Much like neutrality tests from population genetics that use relative abundance distributions have enabled researchers to scan entire genomes for genes under selection, we anticipate our time-series test will be useful for quick significance tests of neutrality across a range of ecological, economic, and sociological systems for which time-series data are available. Future work can use our test to categorize and compare the dynamic fingerprints of particular competitive asymmetries (frequency dependence, volatility smiles, etc) to improve forecasting and management of complex adaptive systems. PMID- 27689716 TI - Avoidance of bottles during the establishment of breast feeds in preterm infants. AB - BACKGROUND: Preterm infants start milk feeds by gavage tube. As they mature, sucking feeds are gradually introduced. Women who choose to breast feed their preterm infant are not always able to be in hospital with their baby and need an alternative approach to feeding. Most commonly, milk (expressed breast milk or formula) is given by bottle. Whether using bottles during establishment of breast feeds is detrimental to breast feeding success is a topic of ongoing debate. OBJECTIVES: To identify the effects of avoidance of bottle feeds during establishment of breast feeding on the likelihood of successful breast feeding, and to assess the safety of alternatives to bottle feeds. SEARCH METHODS: We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 2), MEDLINE via PubMed (1966 to July 2016), Embase (1980 to July 2016) and CINAHL (1982 to July 2016). We also searched databases of clinical trials and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA: Randomised and quasi-randomised controlled trials comparing avoidance of bottles with use of bottles in women who have chosen to breast feed their preterm infant. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trial quality and extracted data. When appropriate, we contacted study authors for additional information. Review authors used standard methods of The Cochrane Collaboration and the Cochrane Neonatal Review Group. MAIN RESULTS: We included seven trials with 1152 preterm infants. Five studies used a cup feeding strategy, one used a tube feeding strategy and one used a novel teat when supplements to breast feeds were needed. We included the novel teat study in this review, as the teat was designed to more closely mimic the sucking action of breast feeding. The trials were of small to moderate size, and two had high risk of attrition bias. Adherence with cup feeding was poor in one of the studies, indicating dissatisfaction with this method by staff and/or parents; the remaining four cup feeding studies provided no such reports of dissatisfaction or low adherence. Meta-analyses provided evidence of low to moderate quality indicating that avoiding bottles increases the extent of breast feeding on discharge home (full breast feeding typical risk ratio (RR) 1.47, 95% confidence interval (CI) 1.19 to 1.80; any breast feeding RR 1.11, 95% CI 1.06 to 1.16). Limited available evidence for three months and six months post discharge shows that avoiding bottles increases the occurrence of full breast feeding and any breast feeding at discharge and at six months post discharge, and of full (but not any) breast feeding at three months post discharge. This effect was evident at all time points for the tube alone strategy and for all except any breast feeding at three months post discharge for cup feeding. Investigators reported no clear benefit when the novel teat was used. No other benefits or harms were evident, including, in contrast to the previous (2008) review, length of hospital stay. AUTHORS' CONCLUSIONS: Evidence of low to moderate quality suggests that supplementing breast feeds by cup increases the extent and duration of breast feeding. Current insufficient evidence provides no basis for recommendations for a tube alone approach to supplementing breast feeds. PMID- 27689715 TI - Affective Disorders, Psychosis and Dementia in a Community Sample of Older Men with and without Parkinson's Disease. AB - BACKGROUND: Dementia and affective and psychotic symptoms are commonly associated with Parkinson's disease, but information about their prevalence and incidence in community representative samples remains sparse. METHODS: We recruited a community-representative sample 38173 older men aged 65-85 years in 1996 and used data linkage to ascertain the presence of PD, affective disorders, psychotic disorders and dementia. Diagnoses followed the International Classification of Disease coding system. Age was recorded in years. Follow up data were available until December 2011. RESULTS: The mean age of participants was 72.5 years and 333 men (0.9%) had PD at study entry. Affective and psychotic disorders and dementia were more frequent in men with than without PD (respective odds ratios: 6.3 [95%CI = 4.7, 8.4]; 14.2 [95%CI = 8.4, 24.0] and 18.2 [95%CI = 13.4, 24.6]). Incidence rate ratios of affective and psychotic disorders were higher among men with than without PD, although ratios decreased with increasing age. The age adjusted hazard ratio (HR) of an affective episode associated with PD was 5.0 (95%CI = 4.2, 5.9). PD was associated with an age-adjusted HR of 8.6 (95%CI = 6.1, 12.0) for psychotic disorders and 6.1 (95%CI = 5.5, 6.8) for dementia. PD and dementia increased the HR of depressive and psychotic disorders. CONCLUSIONS: PD increases the risk of affective and psychotic disorders, as well as dementia, among community dwelling older men. The risk of a recorded diagnosis of affective and psychotic disorders decreases with increasing age. PMID- 27689717 TI - Phase i trials in melanoma: A framework to translate preclinical findings to the clinic. AB - BACKGROUND: One of major issues in clinical trials in oncology is their high failure rate, despite the fact that the trials were designed based on the data from successful equivalent preclinical studies. This is in part due to the intrinsic homogeneity of preclinical model systems and the contrasting heterogeneity of actual patient responses. METHODS: We present a mathematical model-driven framework, phase i (virtual/imaginary) trials, that integrates the heterogeneity of actual patient responses and preclinical studies through a cohort of virtual patients. The framework includes an experimentally calibrated mathematical model, a cohort of heterogeneous virtual patients, an assessment of stratification factors, and treatment optimisation. We show the detailed process through the lens of melanoma combination therapy (chemotherapy and an AKT inhibitor), using both preclinical and clinical data. RESULTS: The mathematical model predicts melanoma treatment response and resistance to mono and combination therapies and was calibrated and then validated with in vitro experimental data. The validated model and a genetic algorithm were used to generate virtual patients whose tumour volume responses to the combination therapy matched statistically the actual heterogeneous patient responses in the clinical trial. Analyses on simulated cohorts revealed key model parameters such as a tumour volume doubling rate and a therapy-induced phenotypic switch rate that may have clinical correlates. Finally, our approach predicts optimal AKT inhibitor scheduling suggesting more effective but less toxic treatment strategies. CONCLUSION: Our proposed computational framework to implement phase i trials in cancer can readily capture observed heterogeneous clinical outcomes and predict patient survival. Importantly, phase i trials can be used to optimise future clinical trial design. PMID- 27689718 TI - Predicting the Dynamics and Heterogeneity of Genomic DNA Content within Bacterial Populations across Variable Growth Regimes. AB - For many applications in microbial synthetic biology, optimizing a desired function requires careful tuning of the degree to which various genes are expressed. One challenge for predicting such effects or interpreting typical characterization experiments is that in bacteria such as E. coli, genome copy number varies widely across different phases and rates of growth, which also impacts how and when genes are expressed from different loci. While such phenomena are relatively well-understood at a mechanistic level, our quantitative understanding of such processes is essentially limited to ideal exponential growth. In contrast, common experimental phenomena such as growth on heterogeneous media, metabolic adaptation, and oxygen restriction all cause substantial deviations from ideal exponential growth, particularly as cultures approach the higher densities at which industrial biomanufacturing and even routine screening experiments are conducted. To meet the need for predicting and explaining how gene dosage impacts cellular functions outside of exponential growth, we here report a novel modeling strategy that leverages agent-based simulation and high performance computing to robustly predict the dynamics and heterogeneity of genomic DNA content within bacterial populations across variable growth regimes. We show that by feeding routine experimental data, such as optical density time series, into our heterogeneous multiphasic growth simulator, we can predict genomic DNA distributions over a range of nonexponential growth conditions. This modeling strategy provides an important advance in the ability of synthetic biologists to evaluate the role of genomic DNA content and heterogeneity in affecting the performance of existing or engineered microbial functions.

AB - Broadband high transmittance, good mechanical robustness as well as simple and low temperature fabrication are three important aspects that dictate the practical applications of superhydrophobic thin films, especially on organic substrates. However, it has proved difficult to meet these challenges. In the present work, superhydrophobic thin films were prepared by first dip-coating solid silica nanoparticles, then spray-coating hollow silica nanoparticles, followed by spray-coating mesoporous silica nanosheets & poly(vinyl alcohol) (PVA), and eventually chemical vapor deposition of 1H,1H,2H,2H perflurooctyltriethoxysilane (POTS) at 90 degrees C. The optimized thin film has a maximum transmittance of 96.0% in the wavelength range of 300-2500nm and a WCA of 164 degrees and a RA of 1 degrees . The thin film also shows good mechanical robustness toward water droplet impact test, sand impact abrasion test and tape adhesion tests, which results from PVA as a binder, the formation of covalent bond between the hydroxyl group of PVA and the ethoxy group of POTS and the chemical inertness of CC, CF bonds of POTS molecules. To our best knowledge, it is the first example where antireflective and superhydrophobic thin films of excellent mechanical robustness were realized at low temperature on organic substrates (PMMA, PC). The current work would provide a promising route to meet the challenges in practical applications simultaneously posed by the requirements of broadband antireflection, good mechanical robustness as well as simple and low temperature fabrication of superhydrophobic thin films.

AB - This study aimed to obtain information on bile acid profiles in diabetic (db/db) mice and their wild type (wt) littermates for the understanding of pathogenesis and discovery of potential biomarkers of type 2 diabetes. Analytical methods based on protein precipitation or solid-phase extraction together with liquid chromatography-tandem mass spectrometry were developed for the determination of 25 bile acids in plasma, urine and feces samples collected from db/db and wt mice. GLP-1 concentration and hepatic genes related to bile acid synthesis were also investigated. The results showed that the concentrations of individual bile acids varied notably both interindividually and temporally. However, plasma, urine and feces samples displayed discriminating bile acid profiles between the db/db and wt groups, with the plasma profile showing the best differentiation capacity. In plasma and urine, the concentration variation of taurine-conjugated bile acids was more correlated with that of other taurine-conjugated bile acids, and vice versa for the unconjugated bile acids. Transcription of hepatic gene Cyp7b1 was downregulated, and Hsd3b7 upregulated in db/db mice. In conclusion, the bile acid profile, particularly that in plasma, can distinguish the two animal groups and is a promising biomarker for type 2 diabetes. PMID- 27689721 TI - Facile synthesis, structure and enhanced photocatalytic activity of novel BiOBr/Bi(C2O4)OH composite photocatalysts. AB - Novel composite photocatalysts BiOBr/Bi(C2O4)OH were successfully fabricated via a chemical etching method. After flower-like Bi(C2O4)OH microstructure assembled by nanorods was etched by KBr under an appropriate acidic condition, BiOBr nano rods could be in-situ generated in nanorods, forming a heterostructure. The heterostructures exhibited a commendable photocatalytic performance toward the degradation of rhodamine B under the visible light irradiation. The effective separation and transfer of the photogenerated electrons and holes were believed to be the main factor for the enhanced activity, which resulted from the intrinsic characteristic of p-n junction. The responsible mechanism was detailedly discussed, and the photogenerated holes and O2- radicals were confirmed to be the main active species for the photodegradation of RhB. PMID- 27689722 TI - Microfluidic synthesis of Ag@Cu2O core-shell nanoparticles with enhanced photocatalytic activity. AB - A microfluidic-based method for the continuous synthesis of Ag@Cu2O core-shell nanoparticles (NPs) has been developed. It only took 32s to obtain Ag@Cu2O core shell NPs, indicating a high efficiency of this microfluidic-based method. Triangular Ag nanoprisms were employed as the cores for the overgrowth of Cu2O through the reduction of Cu(OH)42- with ascorbic acid. The as-synthesized samples were characterized by XRD, TEM, SEM, HAADF-STEM, EDX, HRTEM, UV-vis spectra and N2 adsorption-desorption. The characterization results revealed that the as synthesized Ag@Cu2O core-shell NPs exhibited a well-defined core-shell nanostructure with a polycrystalline shell, which was composed of numbers of Cu2O domains epitaxially growing on the triangular Ag nanoprism. It was concluded that the synthesis parameters such as the molar ratio of trisodium citrate to AgNO3, H2O2 to AgNO3, NaOH to CuSO4, ascorbic acid to CuSO4 and AgNO3 to CuSO4 had significant effect on the synthesis of Ag@Cu2O core-shell NPs. Moreover, Ag@Cu2O core-shell NPs exhibited superior catalytic activity in comparison with pristine Cu2O NPs towards the visible light-driven degradation of methyl orange. This enhanced photocatalytic activity of Ag@Cu2O core-shell NPs was attributed to the larger BET surface area and improved charge separation efficiency. The trapping experiment indicated that holes and superoxide anion radicals were the major reactive species in the photodegradation of methyl orange over Ag@Cu2O core-shell NPs. In addition, Ag@Cu2O core-shell NPs showed no obvious deactivation in the cyclic test. PMID- 27689723 TI - Population Size, Growth, and Environmental Justice Near Oil and Gas Wells in Colorado. AB - We evaluated population size and factors influencing environmental justice near oil and gas (O&G) wells. We mapped nearest O&G well to residential properties to evaluate population size, temporal relationships between housing and O&G development, and 2012 housing market value distributions in three major Colorado O&G basins. We reviewed land use, building, real estate, and state O&G regulations to evaluate distributive and participatory justice. We found that by 2012 at least 378,000 Coloradans lived within 1 mile of an active O&G well, and this population was growing at a faster rate than the overall population. In the Denver Julesburg and San Juan basins, which experienced substantial O&G development prior to 2000, we observed a larger proportion of lower value homes within 500 feet of an O&G well and that most O&G wells predated houses. In the Piceance Basin, which had not experienced substantial prior O&G development, we observed a larger proportion of high value homes within 500 feet of an O&G well and that most houses predated O&G wells. We observed economic, rural, participatory, and/or distributive injustices that could contribute to health risk vulnerabilities in populations near O&G wells. We encourage policy makers to consider measures to reduce these injustices.

AB - Coagulation factor Xa (fXa) is a particularly attractive target for the development of effective and safe anticoagulants. In this study, novel 2,3 dihydroquinazolin-4(1H)-one derivatives were designed as potential fXa inhibitors based on anthranilamide structure which has been reported in our previous research. The experimental data showed that most of the designed compounds exhibited significant in vitro potency against fXa. Among them, compound 8e displayed the strongest potency against fXa with the IC50 value of 21 nM and highly selectivity versus thrombin (IC50 = 67 MUM) and excellent in vitro antithrombotic activity with its 2 * PT value of 1.2 MUM and 2 * aPTT value of 0.6 MUM. In addition, 8e also displayed excellent in vivo antithrombotic activity in the rat arteriovenous shunt (AV-SHUNT) model. The bleeding risk evaluation showed that 8e had a similar safety profile as that of betrixaban. All results demonstrated that compound 8e could be considered as a potential fXa inhibitor for the prevention and treatment of thromboembolic diseases. PMID- 27689725 TI - Synthesis, in vitro evaluation and molecular docking studies of novel triazine triazole derivatives as potential alpha-glucosidase inhibitors. AB - A novel series of triazine-triazole derivatives 7a-7m were synthesized, characterized by 1H NMR and evaluated for their alpha-glucosidase inhibitory activity. All the synthesized compounds displayed potent alpha-glucosidase inhibitory activity with IC50 range of 11.63 +/- 0.15 to 37.44 +/- 0.35 MUM, when compared to the standard drug acarbose (IC50 = 817.38 +/- 6.27 MUM). Among the series, compound 7i (IC50 = 11.63 +/- 0.15 MUM) bearing 2,5-dichloro substitution at phenyl ring, represented the most potent alpha-glucosidase inhibitory activity. Molecular docking studies of the most active compounds with the homology modelled alpha-glucosidase were also performed to explore the possible inhibitory mechanism. Our studies shown that these triazine-triazole derivatives are a new class of alpha-glucosidase inhibitors.

AB - Drug repurposing (=drug repositioning) is an effective way to cut costs for the development of new therapeutics and to reduce the time-to-market time-span. Following this concept a small library of compounds was screened for their ability to act as inhibitors of acetyl- and butyrylcholinesterase. Picloxydine, an established antiseptic, was shown to be an inhibitor for both enzymes. Systematic variation of the aryl substituents led to analogs possessing almost the same good properties as gold standard galantamine hydrobromide.

AB - Recently, 1-(1,4-dioxaspiro[4,5]dec-2-ylmethyl)-4-(2-methoxyphenyl)piperazine (1) was reported as a potent 5-HT1AR agonist with a moderate 5-HT1AR selectivity. In an extension of this work a series of derivatives of 1, obtained by combining different heterocyclic rings with a more flexible amine chain, was synthesized and tested for binding affinity and activity at 5-HT1AR and alpha1 adrenoceptors. The results led to the identification of 14 and 15 as novel 5-HT1AR partial agonists, the first being outstanding for selectivity (5-HT1A/alpha1d = 80), the latter for potency (pD2 = 9.58) and efficacy (Emax = 74%). Theoretical studies of ADME properties shows a good profile for the entire series and MDCKII-MDR1 cells permeability data predict a good BBB permeability of compound 15, which possess a promising neuroprotective activity. Furthermore, in mouse formalin test, compound 15 shows a potent antinociceptive activity suggesting a new strategy for pain control. PMID- 27689728 TI - Piperlongumine (piplartine) and analogues: Antiproliferative microtubule destabilising agents. AB - Piperlongumine (piplartine, 1) is a small molecule alkaloid that is receiving intense interest due to its antiproliferative and anticancer activities. We investigated the effects of 1 on tubulin and microtubules. Using both an isolated tubulin assay, and a combination of sedimentation and western blotting, we demonstrated that 1 is a tubulin-destabilising agent. This result was confirmed by immunofluorescence and confocal microscopy, which showed that microtubules in MCF-7 breast cancer cells were depolymerized when treated with 1. We synthesised a number of analogues of 1 to explore structure-activity relationships. Compound 13 had the best cytotoxic profile of this series, showing potent effects in human breast carcinoma MCF-7 cells whilst being relatively non-toxic to non-tumorigenic MCF-10a cells. These compounds will be further developed as potential clinical candidates for the treatment of breast cancer. PMID- 27689729 TI - Natural and synthetic bioactive inhibitors of glycogen synthase kinase. AB - Glycogen synthase kinase-3 is a multi-functional serine-threonine kinase and is involved in diverse physiological processes, including metabolism, cell cycle, and gene expression by regulating a wide variety of known substrates like glycogen synthase, tau-protein and beta-catenin. Aberrant GSK-3 has been involved in diabetes, inflammation, cancer, Alzheimer's and bipolar disorder. In this review, we present an overview of the involvement of GSK-3 in various signalling pathways, resulting in a number of adverse pathologies due to its dysregulation. In addition, a detailed description of the small molecule inhibitors of GSK-3 with different mode of action discovered or specifically developed for GSK-3 has been presented. Furthermore, some clues for the future optimization of these promising molecules to develop specific drugs inhibiting GSK-3, for the treatment of associated disease conditions have also been discussed. PMID- 27689730 TI - Development of resveratrol-curcumin hybrids as potential therapeutic agents for inflammatory lung diseases. AB - Acute lung injury (ALI) is a major cause of acute respiratory failure in critically-ill patients. Resveratrol and curcumin are proven to have potent anti inflammatory efficacy, but their clinical application is limited by their metabolic instability. Here, a series of resveratrol and the Mono-carbonyl analogs of curcumin (MCAs) hybrids were designed and synthesized by efficient aldol construction strategy, and then screened for anti-inflammatory activities in vitro and in vivo. The results showed that the majority of analogs effectively inhibited the LPS-induced production of IL-6 and TNF-alpha. Five analogs, a9, a18, a19, a20 and a24 exhibited excellent anti-inflammatory activity in a dose dependent manner along with low toxicity in vitro. Structure activity relationship study revealed that the electron-withdrawing groups at meta-position and methoxyl group (OCH3) at the para position of the phenyl ring were important for anti-inflammatory activities. The most promising compound a18 decreased LPS induced TNF-alpha, IL-6, IL-12, and IL-33 mRNA expression. Additionally, a18 significantly protected against LPS-induced acute lung injury in the in vivo mouse model. The research of resveratrol and MCAs hybrids could bring insight into the treatment of inflammatory diseases and compound a18 may serve as a lead compound for the development of anti-ALI agents. PMID- 27689731 TI - Structure-activity relationships and optimization of acyclic acylphloroglucinol analogues as novel antimicrobial agents. AB - Methicillin-resistant Staphylococcus aureus (MRSA) poses a serious threat to global public health, because it exhibits resistance to existing antibiotics and therefore high rates of morbidity and mortality. In this study, twenty-one natural product-based acylphloroglucinol congeners were synthesized, which possessed different side chains. Antibacterial screening against MRSA strains revealed that acyl moiety tailoring is a prerequisite for the antibacterial activity. Moreover, the lipophilicity, rather than the magnitude of the hydrophobic acyl tail dominates variability in activity potency. Compound 11j was identified as a promising lead for the generation of new anti-MRSA drug development. It was discovered by optimization of the side chain length in light of the potency, the breadth of the antibacterial spectrum, the rate of bactericidal action, as well as the membrane selectivity. Compound 11j exerted profound in vitro antibacterial activity against the MRSA strain (JCSC 2172), and its MIC was 3-4 orders of magnitude lower than that of vancomycin. A preliminary mode of action study of compound 11j at the biophysical and morphology levels disclosed that the mechanism underlying its anti-MRSA activity included membrane depolarization and, to a lesser extent, membrane disruption and cell lysis. PMID- 27689732 TI - Linker-switch approach towards new ATP binding site inhibitors of DNA gyrase B. AB - Due to increasing emergence of bacterial resistance, compounds with new mechanisms of action are of paramount importance. One of modestly researched therapeutic targets in the field of antibacterial discovery is DNA gyrase B. In the present work we synthesized a focused library of potential DNA gyrase B inhibitors composed of two key pharmacophoric moieties linked by three types of sp3-rich linkers to obtain three structural classes of compounds. Using molecular docking, molecular dynamics and analysis of conserved waters in the binding site, we identified a favourable binding mode for piperidin-4-yl and 4-cyclohexyl pyrrole-2-carboxamides while predicting unfavourable interactions with the active site for piperazine pyrrole-2-carboxamides. Biological evaluation of prepared compounds on isolated enzyme DNA gyrase B confirmed our predictions and afforded multiple moderately potent inhibitors of DNA gyrase B. Namely trans-4-(4,5 dibromo-1H-pyrrole-2-carboxamide)cyclohexyl)glycine and 4-(4-(3,4-dichloro-5 methyl-1H-pyrrole-2-carboxamido)piperidin-1-yl)-4-oxobutanoic acid with an IC50 value of 16 and 0.5 MUM respectively.

PMID- 27689733 TI - Synthesis, evaluation, and CoMFA study of fluoroquinophenoxazine derivatives as bacterial topoisomerase IA inhibitors. AB - New antibacterial agents with novel target and mechanism of action are urgently needed to combat problematic bacterial infections and mounting antibiotic resistances. Topoisomerase IA represents an attractive and underexplored antibacterial target, as such, there is a growing interest in developing selective and potent topoisomerase I inhibitors for antibacterial therapy. Based on our initial biological screening, fluoroquinophenoxazine 1 was discovered as a low micromolar inhibitor against E. coli topoisomerase IA. In the literature, fluoroquinophenoxazine analogs have been investigated as antibacterial and anticancer agents, however, their topoisomerase I inhibition was relatively underexplored and there is little structure-activity relationship (SAR) available. The good topoisomerase I inhibitory activity of 1 and the lack of SAR prompted us to design and synthesize a series of fluoroquinophenoxazine analogs to systematically evaluate the SAR and to probe the structural elements of the fluoroquinophenoxazine core toward topoisomerase I enzyme target recognition. In this study, a series of fluoroquinophenoxazine analogs was designed, synthesized, and evaluated as topoisomerase I inhibitors and antibacterial agents. Target based assays revealed that the fluoroquinophenoxazine derivatives with 9-NH2 and/or 6-substituted amine functionalities generally exhibited good to excellent inhibitory activities against topoisomerase I with IC50s ranging from 0.24 to 3.9 MUM. Notably, 11a bearing the 6-methylpiperazinyl and 9-amino motifs was identified as one of the most potent topoisomerase I inhibitors (IC50 = 0.48 MUM), and showed broad spectrum antibacterial activity (MICs = 0.78-7.6 MUM) against all the bacteria strains tested. Compound 11g with the 6-bipiperidinyl lipophilic side chain exhibited the most potent antituberculosis activity (MIC = 2.5 MUM, SI = 9.8). In addition, CoMFA analysis was performed to investigate the 3D-QSAR of this class of fluoroquinophenoxazine derivatives. The constructed CoMFA model produced reasonable statistics (q2 = 0.688 and r2 = 0.806). The predictive power of the developed model was obtained using a test set of 7 compounds, giving a predictive correlation coefficient r2pred of 0.767. Collectively, these promising data demonstrated that fluoroquinophenoxazine derivatives have the potential to be developed as a new chemotype of potent topoisomerase IA inhibitors with antibacterial therapeutic potential.

PMID- 27689735 TI - Baricitinib in patients with inadequate response or intolerance to conventional synthetic DMARDs: results from the RA-BUILD study. AB - BACKGROUND: Baricitinib is an oral, reversible, selective Janus kinase 1 and 2 inhibitor. METHODS: In this phase III, double-blind 24-week study, 684 biologic disease-modifying antirheumatic drug (DMARD)-naive patients with rheumatoid arthritis and inadequate response or intolerance to >=1 conventional synthetic DMARDs were randomly assigned 1:1:1 to placebo or baricitinib (2 or 4 mg) once daily, stratified by region and the presence of joint erosions. Endpoint measures included American College of Rheumatology 20% response (ACR20, primary endpoint), Disease Activity Score (DAS28) and Simplified Disease Activity Index (SDAI) score <=3.3. RESULTS: More patients achieved ACR20 response at week 12 with baricitinib 4 mg than with placebo (62% vs 39%, p<=0.001). Compared with placebo, statistically significant improvements in DAS28, SDAI remission, Health Assessment Questionnaire-Disability Index, morning joint stiffness, worst joint pain and worst tiredness were observed. In a supportive analysis, radiographic progression of structural joint damage at week 24 was reduced with baricitinib versus placebo. Rates of adverse events during the treatment period and serious adverse events (SAEs), including serious infections, were similar among groups (SAEs: 5% for baricitinib 4 mg and placebo). One patient had an adverse event of tuberculosis (baricitinib 4 mg); one patient had an adverse event of non-melanoma skin cancer (baricitinib 4 mg). Two deaths and three major adverse cardiovascular events occurred (placebo). Baricitinib was associated with a decrease in neutrophils and increases in low-density and high-density lipoprotein. CONCLUSIONS: In patients with rheumatoid arthritis and an inadequate response or intolerance to conventional synthetic DMARDs, baricitinib was associated with clinical improvement and inhibition of progression of radiographic joint damage.

PMID- 27689739 TI - The influence of abscisic acid on the ethylene biosynthesis pathway in the functioning of the flower abscission zone in Lupinus luteus. AB - Flower abscission is a highly regulated developmental process activated in response to exogenous (e.g. changing environmental conditions) and endogenous stimuli (e.g. phytohormones). Ethylene (ET) and abscisic acid (ABA) are very effective stimulators of flower abortion in Lupinus luteus, which is a widely cultivated species in Poland, Australia and Mediterranean countries. In this paper, we show that artificial activation of abscission by flower removal caused an accumulation of ABA in the abscission zone (AZ). Moreover, the blocking of that phytohormone's biosynthesis by NDGA (nordihydroguaiaretic acid) decreased the number of abscised flowers. However, the application of NBD - an inhibitor of ET action - reversed the stimulatory effect of ABA on flower abscission, indicating that ABA itself is not sufficient to turn on the organ separation. Our analysis revealed that exogenous ABA significantly accelerated the transcriptional activity of the ET biosynthesis genes ACC synthase (LlACS) and oxidase (LlACO), and moreover, strongly increased the level of 1 aminocyclopropane-1-carboxylic acid (ACC) - ET precursor, which was specifically localized within AZ cells. We cannot exclude the possibility that ABA mediates flower abscission processes by enhancing the ET biosynthesis rate. The findings of our study will contribute to the overall basic knowledge on the phytohormone regulated generative organs abscission in L. luteus. PMID- 27689738 TI - Salinity stress from the perspective of the energy-redox axis: Lessons from a marine intertidal flatworm. AB - In the context of global change, there is an urgent need for researchers in conservation physiology to understand the physiological mechanisms leading to the acquisition of stress acclimation phenotypes. Intertidal organisms continuously cope with drastic changes in their environmental conditions, making them outstanding models for the study of physiological acclimation. As the implementation of such processes usually comes at a high bioenergetic cost, a mitochondrial/oxidative stress approach emerges as the most relevant approach when seeking to analyze whole-animal responses. Here we use the intertidal flatworm Macrostomum lignano to analyze the bioenergetics of salinity acclimation and its consequences in terms of reactive oxygen/nitrogen species formation and physiological response to counteract redox imbalance. Measures of water fluxes and body volume suggest that M. lignano is a hyper-/iso-regulator. Higher salinities were revealed to be the most energetically expensive conditions, with an increase in mitochondrial density accompanied by increased respiration rates. Such modifications came at the price of enhanced superoxide anion production, likely associated with a high caspase 3 upregulation. These animals nevertheless managed to live at high levels of environmental salinity through the upregulation of several mitochondrial antioxidant enzymes such as superoxide dismutase. Contrarily, animals at low salinities decreased their respiration rates, reduced their activity and increased nitric oxide formation, suggesting a certain degree of metabolic arrest. A contradictory increase in dichlorofluorescein fluorescence and an upregulation of gluthathione-S-transferase pi 1 (GSTP1) expression were observed in these individuals. If animals at low salinity are indeed facing metabolic depression, the return to seawater may result in an oxidative burst. We hypothesize that this increase in GSTP1 could be a "preparation for oxidative stress", i.e. a mechanism to counteract the production of free radicals upon returning to seawater. The results of the present study shed new light on how tolerant organisms carry out subcellular adaptations to withstand environmental change.

AB - Soil-borne plant pathogens such as nematodes, fungi and some bacteria not only affect the plant cultures but also economy and environmental implications. As a result of these pathogens attacks, the yield and quality of crops is affected. Therefore, synthesis of new compounds to control these pathogens is very important and need of time. Chromenes are considered important group of heterocyclic compounds and exhibited significant biological activities. 2-amino-3 cyano chromenes are considered important medicinal scaffolds among the chromenes. We describe three component microwave assisted synthesis of 2-amino-3-cyano chromenes. The versatility of the reaction was examined by varying the aldehydes in the reaction mixture which lead to the synthesis of series of 2-amino-3 cyanochromenes (1-9). The structural elucidations of the compounds were studied by 1H NMR, 13C NMR, HRMS and FTIR spectrometer and results were well correlated. The synthesized compounds were evaluated for their anti-bacterial, anti-fungal and nematicidal activities. Among the synthesized compounds, compound 6 showed good anti-bacterial activity while compound 9 exhibited high anti-fungal activity. In case of nematicidal activity, compound 8 indicated high activity as compare with other compounds followed by compound 9. Results indicate that these synthesized compounds could be used as effective control for soil-borne plant pathogens such as nematodes, fungi and bacteria and can help to improve the plant production. PMID- 27689741 TI - Sapium sebiferum leaf extract mediated synthesis of palladium nanoparticles and in vitro investigation of their bacterial and photocatalytic activities. AB - There is a growing need to introduce eco-friendly and sustainable procedures for the synthesis of metal nanoparticles that include a mild reaction conditions, simple reaction setup, use of nontoxic medium such as water and plant extract, cost effectiveness as well as greater efficiency for biomedical and catalytic applications. For this purpose, small and highly dispersed palladium nanoparticles (PdNPs) were prepared by eco-friendly and cost effective green method using water soluble leaf extract of Sapium sebiferum as a reducing and capping agent. The formation of PdNPs was optimized at various temperatures i.e. (30 degrees C, 60 degrees C and 90 degrees C) and different leaves extract (5mL and 10mL) in order to control their size and shape. The results indicated that PdNPs synthesized at 10mL leaf extract concentration and 60 degrees C temperature have small sized (5nm) and spherical shape. The nanoparticles formation, their dispersion, size and shape were confirmed by various characterization techniques i.e. UV-Vis spectroscopy, Fourier-transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), thermo gravimetric analysis (TGA) and Dynamic light scattering technique (DLS) analysis. The biologically synthesized PdNPs were tested for size dependent photo degradation of methylene blue and inactivation of bacteria. The PdNPs synthesized at optimized condition (10mL extract concentration and 60 degrees C) have strong photo catalytic activity and reduced 90% methylene blue in 70min. The optimized PdNPs also showed strong bacterial inhibition against Staphylococcus aureus 29(+/-0.8mm), Bacillus subtilis 19(+/-0.6mm) and pseudomonas aeruginosa 11(+/-0.6mm). The results of this examination demonstrate effective applications of extremely active PdNPs. PMID- 27689742 TI - Toxicity and efficacy of CdO nanostructures on the MDCK and Caki-2 cells. AB - This article reports the toxicological effects of synthesized cadmium oxide (CdO) nanostructures via a simple green route using a Polygala tenuifolia root extract on normal and renal tumor cells. First, the formation of cadmium oxide nanostructures were confirmed structurally by Fourier transform infrared spectroscopy, X-ray diffraction, and X-ray photoelectron spectroscopy (XPS). The powder was crystallized in a cubic structure with a space group of Fm-3m. The mean crystallize size was approximately 40 and 44nm from the Scherrer and size strain plots, respectively. The surface states of the cadmium oxide nanostructure using the O 1s and Cd 3d spectra were analyzed by XPS. Transmission electron microscopy showed that the simple green route resulted in various morphologies of synthesized cadmium oxide, such as trigonal-, tetrahedron-, and sheet-like structures. Finally, the toxic effects of the cadmium oxide nanostructures on Madin-Darby canine kidney epithelial cells (MDCK cells), as well as the human renal cancer cell line (Caki-2 cells) were investigated using a SRB assay and two color flow cytometry analysis. The cadmium oxide nanostructures showed significant cell growth inhibition in normal and also tumor cells in a dose dependent manner. On the other hand, the inhibition was higher in the cancer cells compared to the normal cells.

PMID- 27689744 TI - Novel function of FAXDC2 in megakaryopoiesis. AB - FAXDC2 (fatty acid hydroxylase domain containing 2) is a member of the fatty acid hydroxylase superfamily. Given the important role of fatty acids in megakaryocytes, we have studied the role of this gene in the development of this lineage. Here we show that the expression of FAXDC2 is constantly elevated during megakaryocyte maturation. In contrast, FAXDC2 is significantly downregulated in acute myeloid leukemia and acute megakaryoblastic leukemia. Moreover, FAXDC2 overexpression promotes the differentiation of megakaryocytic cell lines and primary cells, whereas its knockdown disrupts their maturation. Mechanism study shows that FAXDC2 overexpression enhances extracellular signal-regulated kinase (ERK) signaling and increases RUNX1 (Runt-related transcription factor 1) expression. FAXDC2 also restores megakaryocytic differentiation in cells exposed to an ERK inhibitor or those expressing a dominant negative form of RUNX1. Finally, FAXDC2 overexpression leads to an increase in sphingolipid GM3 synthase, suggesting a potential role of FAXDC2 in lipid metabolism that increases ERK signaling and facilitates megakaryocyte differentiation. Together, these results show that FAXDC2 plays a novel role in development of megakaryocytes and its dysregulation may contribute to abnormal hematopoietic cell development in leukemia. PMID- 27689745 TI - Palladium(II)-Catalyzed Enantioselective Reactions Using COP Catalysts. AB - Allylic amides, amines, and esters are key synthetic building blocks. Their enantioselective syntheses under mild conditions is a continuing pursuit of organic synthesis methods development. One opportunity for the synthesis of these building blocks is by functionalization of prochiral double bonds using palladium(II) catalysis. In these reactions, nucleopalladation mediated by a chiral palladium(II) catalyst generates a new heteroatom-substituted chiral center. However, reactions where nucleopalladation occurs with antarafacial stereoselectivity are difficult to render enantioselective because of the challenge of transferring chiral ligand information across the square-planar palladium complex to the incoming nucleophile. In this Account, we describe the development and use of enantiopure palladium(II) catalysts of the COP (chiral cobalt oxazoline palladacyclic) family for the synthesis of enantioenriched products from starting materials derived from prochiral allylic alcohols. We begin with initial studies aimed at rendering catalyzed [3,3]-sigmatropic rearrangements of allylic imidates enantioselective, which ultimately led to the identification of the significant utility of the COP family of Pd(II) catalysts. The first use of an enantioselective COP catalyst was reported by Richards' and our laboratories in 2003 for the enantioselective rearrangement of allylic N arylimidates. Shortly thereafter, we discovered that the chloride-bridged COP dimer, [COP-Cl]2, was an excellent enantioselective catalyst for the rearrangement of (E)-allylic trichloroacetimidates to enantioenriched allylic trichloroacetamides, this conversion being the most widely used of the allylic imidate rearrangements. We then turn to discuss SN2' reactions catalyzed by the acetate-bridged COP dimer, [COP-OAc]2, which proceed by a unique mechanism to provide branched allylic esters and allylic phenyl ethers in high enantioselectivity. Furthermore, because of the unique nucleopalladation/deoxypalladation mechanism of these SN2' reactions, they provide exclusively the branched allylic product. Importantly, both enantiomers of the [COP-Cl]2 and [COP-OAc]2 catalysts are commercially available. We also briefly consider several other enantioselective reactions catalyzed by COP complexes. The mechanism of enantioselective COP-catalyzed allylic rearrangements and allylic substitutions is discussed in some detail. In both reactions, nucleopalladation is found to be the enantiodetermining step. The cyclobutadienyl "floor" of the COP catalyst is critical for transmitting chiral information across the palladium square plane in these reactions. This structural feature enables high enantioselection to be realized in spite of the nearly 180 degrees angle between the catalyst, electrophile and nucleophile in the enantiodetermining step. Our discussion concludes by considering several uses of the COP family of catalysts by other researchers for the enantioselective synthesis of biologically active chiral molecules. We anticipate that additional uses for COP catalysts will emerge in the future. In addition, the structural features of these catalysts that we have identified as important for achieving high enantioselection should be useful in the future development of improved enantioselective Pd(II) catalysts. PMID- 27689746 TI - Copper-Mediated C-N Coupling of Arylsilanes with Nitrogen Nucleophiles. AB - A method for the oxidative coupling of arylsilanes with nitrogen nucleophiles is reported. This method occurs with a broad range of heptamethyltrisiloxylarenes and nitrogen nucleophiles, proceeds with the arylsilane as limiting reagent, and does not require a fluoride activator with electron-poor arylsilanes. The combination of this method with C-H silylation generates arylamines from unactivated arenes with site selectivity controlled by steric effects. This combination of steps gives direct access to many compounds that cannot be accessed via alternative C-H functionalization methods, including direct C-H amination or the combination of C-H borylation and amination. PMID- 27689747 TI - Electrically Conductive Hierarchical Carbon Nanotube Networks with Tunable Mechanical Response. AB - Small diameter carbon nanotube (CNTs) are synthesized directly from a parent CNT forest using a floating catalyst chemical vapor deposition (CVD) method. To support a new CNT generation from an existing forest, an alumina coating was applied to the CNT forest using atomic layer deposition (ALD). The new generation of small diameter CNTs (8 nm average) surround the first generation, filling the interstitial regions. The hierarchical forests exhibit a 5-10-fold increase in stiffness, and the two generations are electrically addressable in spite of the interfacial alumina layer between them. This work enables the design of complex CNT architectures with hierarchical features that bring tailored properties such as high specific surface area and robust mechanical properties that can benefit a range of applications. PMID- 27689750 TI - Prolongation of kidney allograft survival regulated by indoleamine 2, 3 dioxygenase in immature dendritic cells generated from recipient type bone marrow progenitors. AB - Immature dendritic cells (iDCs) are bone marrow-derived professional antigen presenting cells, exhibit very low levels of the co-stimulatory molecules CD80 (B7-1), CD86 (B7-2), and CD40 and major histocompatibility complex (MHC) class II and play a critical role in triggering antigen-specific immunotolerance. The enzyme indoleamine 2, 3-dioxygenase (IDO) is a cytosolic tryptophan catabolism rate-limiting step enzyme. IDO secreted by DCs shows an association with the suppression of T-cell responses and promotion of tolerance. In this study, BN rat recipients were pre-injected with donor renal alloantigen-treated recipient iDCs before kidney transplantation. The renal allograft exhibited a lighter renal rejection response, prolonged graft survival time, and an increasing content of CD4+CD25+Foxp3+ regulatory T cells (Tregs). Additionally, up-regulated secretion of Th2 cytokines were found in recipient sera post-transplantation. Transfection of si-IDO1 RNA into renal-antigen-treated recipient iDCs reversed these changes, which suggested that IDO channel signaling may be involved in iDC-induced allograft immunotolerance. These results suggested that iDC-induced and IDO mediated allograft immunotolerance might be a potentially feasible tactic to prolong allograft survival, in addition to immunosuppressive drugs. PMID- 27689749 TI - Tuberculosis-sensitized monocytes sustain immune response of interleukin-37. AB - Roles of human IL-37 in infections remain poorly characterized. Although plasma IL-37 is elevated in patients with tuberculosis (TB), IL-37 source and immune correlate in TB have not been investigated. It is also unknown whether and how TB can influence the ability of immune cells to mount innate responses of IL-37 and pre-inflammatory cytokines. Here, we demonstrated that IL-37b-producing monocytes coincided with a source of elevated plasma IL-37b in TB patients. While IL-37b production in TB was associated with prolonged/complicated TB, TB burdens and inflammatory reactions, it negatively correlated with immune responses of pro inflammatory cytokines IL-1beta, IL-6 and TNF-alpha or IL-10. Interestingly, mycobacterial re-infection of monocytes from TB patients, but not healthy BCG vaccinated controls, enhanced or sustained IL-37b production by cultured monocytes. TB-sensitized monocytes from TB patients mounted more robust immune responses of IL-37b than those of pre-inflammatory cytokines during mycobacterial re-infection in culture. Our data represent new findings in terms of IL-37b responses, immune correlates and potential mechanisms in TB patients. PMID- 27689751 TI - Cholesterol-Based Grafted Polymer Brushes as Alignment Coating with Temperature Tuned Anchoring for Nematic Liquid Crystals. AB - Novel alignment coating with temperature-tuned anchoring for nematic liquid crystals (NLCs) was successfully fabricated in three step process, involving polymerization of poly(cholesteryl methacrylate) (PChMa) from oligoproxide grafted to the glass surface premodified with 3-aminopropyltriethoxysilane. Molecular composition, thickness, wettability of the PChMa coating and its alignment action for a NLC were examined with time of flight-secondary ion mass spectrometry, ellipsometry, contact angle measurements, polarization optical microscopy and commercially produced PolScope technique allowing for mapping of the optic axis and optical retardance within the microscope field view. We find that the PChMa coating provides a specific monotonous increase (decrease) in the tilt angle of the NLC director with respect to the substrates normal upon heating (cooling) referred to as anchoring tuning. PMID- 27689748 TI - Age-related changes in cerebellar and hypothalamic function accompany non microglial immune gene expression, altered synapse organization, and excitatory amino acid neurotransmission deficits. AB - We describe age-related molecular and neuronal changes that disrupt mobility or energy balance based on brain region and genetic background. Compared to young mice, aged C57BL/6 mice exhibit marked locomotor (but not energy balance) impairments. In contrast, aged BALB mice exhibit marked energy balance (but not locomotor) impairments. Age-related changes in cerebellar or hypothalamic gene expression accompany these phenotypes. Aging evokes upregulation of immune pattern recognition receptors and cell adhesion molecules. However, these changes do not localize to microglia, the major CNS immunocyte. Consistent with a neuronal role, there is a marked age-related increase in excitatory synapses over the cerebellum and hypothalamus. Functional imaging of these regions is consistent with age-related synaptic impairments. These studies suggest that aging reactivates a developmental program employed during embryogenesis where immune molecules guide synapse formation and pruning. Renewed activity in this program may disrupt excitatory neurotransmission, causing significant behavioral deficits. PMID- 27689752 TI - Solvent and Heavy-Atom Effects on the O2(X3Sigmag-) -> O2(b1Sigmag+) Absorption Transition. AB - The effect of 16 liquid solvents on both the spectrum and molar absorption coefficient of the X3Sigmag- -> b1Sigmag+ transition in molecular oxygen has been examined. The ability to monitor this weak transition using air or oxygen saturated samples at atmospheric pressure was facilitated by the rapid and efficient O2(b1Sigmag+) -> O2(a1Deltag) transition, which allowed the use of O2(a1Deltag) phosphorescence as a sensitive probe of O2(b1Sigmag+) production. The results of these O2(a1Deltag) phosphorescence experiments are consistent with the results of independent experiments in which the O2(a1Deltag) thus produced was "trapped" via a chemical reaction. The data recorded were used to calculate rate constants for the O2(b1Sigmag+) -> O2(X3Sigmag-) radiative transition, a parameter that is otherwise difficult to directly obtain from such a wide range of solvents using O2(b1Sigmag+) -> O2(X3Sigmag-) phosphorescence. The data show that the response of the O2(b1Sigmag+) -> O2(X3Sigmag-) radiative transition to solvent is not the same as that of the O2(b1Sigmag+) -> O2(a1Deltag) and O2(a1Deltag) -> O2(X3Sigmag-) radiative transitions, both of which have been extensively examined over the years. However, our data are consistent with a theoretical model proposed by Minaev for the effect of solvent on radiative transitions in oxygen and, as such, arguably provide one of the final chapters in describing a system that has challenged the scientific community for years. PMID- 27689753 TI - Remote Substituent Effects on the Structures and Stabilities of P?E pi-Stabilized Diphosphatetrylenes (R2P)2E (E = Ge, Sn). AB - A rare P-E pi interaction between the lone pair of a planar P center and the vacant p orbital at the Ge or Sn center provides efficient stabilization for P substituted tetrylenes (R2P)2E (E = Ge, Sn) and enables isolation of the first example of a compound with a crystallographically authenticated P?Sn bond. Subtle changes in the electronic properties of the bulky aryl substituents in these compounds change the preference for planar versus pyramidal P centers in the solid state; however, variable-temperature NMR spectroscopy indicates that in solution these species are subject to a dynamic equilibrium, which interconverts the planar and pyramidal P centers. Consistent with this, density functional theory studies suggest that there is only a small energy difference between the planar and pyramidal forms of these compounds and reveal a small singlet-triplet energy separation, suggesting potentially interesting reactivities. PMID- 27689754 TI - Synergy between Experimental and Computational Chemistry Reveals the Mechanism of Decomposition of Nickel-Ketene Complexes. AB - A series of (dppf)Ni(ketene) complexes were synthesized and fully characterized. In the solid state, the complexes possess eta2-(C,O) coordination of the ketene in an overall planar configuration. They display similar structure in solution, except in some cases, the eta2-(C,C) coordination mode is also detected. A combination of kinetic analysis and DFT calculations reveals the complexes undergo thermal decomposition by isomerization from eta2-(C,O) to eta2-(C,C) followed by scission of the C?C bond, which is usually rate limiting and results in an intermediate carbonyl carbene complex. Subsequent rearrangement of the carbene ligand is rate limiting for electron poor and sterically large ketenes, and results in a carbonyl alkene complex. The alkene readily dissociates, affording alkenes and (dppf)Ni(CO)2. Computational modeling of the decarbonylation pathway with partial phosphine dissociation reveals the barrier is reduced significantly, explaining the instability of ketene complexes with monodentate phosphines. PMID- 27689755 TI - Different forms of alpha-1 antitrypsin and neutrophil activation mediated by human anti-PR3 IgG antibodies. AB - BACKGROUND: One of characteristic findings in granulomatosis with polyangiitis (GPA) is the presence of proteinase-3 (anti-PR3) specific antibodies. These antibodies can cause neutrophil activation, degranulation and generation of reactive oxygen species (ROS). Each of these inflammatory events can be suppressed by circulating alpha-1 antitrypsin (A1AT). A1AT is an acute phase protein increasing during inflammation, however, it may circulate as an inactive polymeric protein. The aim was to analyze how different types of A1AT can affect anti-PR3 mediated neutrophil activation. METHODS: Granulocytes were obtained from the blood of healthy volunteers and purified by density gradient centrifugation. Effects of A1AT on IgG anti-PR3-mediated neutrophil activation were evaluated by stimulation of the cells with native IgG anti-PR3 antibodies in the presence of native or polymerized A1AT. Analyses of selected proinflammatory genes expression were performed using quantitative real-time. Flow cytometry was used to study the cell membrane PR3, its binding by anti-PR3 IgG, and production of ROS at presence A1AT. Neutrophil elastase complexes with A1AT were measured by ELISA. RESULTS: Native A1AT inhibited formation of the immune complex of PR3 with anti-PR3 and anti-PR3-mediated neutrophil activation/ROS production. Protective effect of polymerized A1AT against these events was diminished at least fivefold. CONCLUSIONS: Native A1AT can prevent pivotal events of neutrophils' activation by anti-PR3 IgG, the main autoantibody in anti-PR3 dependent vasculitis. Inhibitory properties of polymerized A1AT, decreased plausibly due to a loss of anti protease function, can explain more severe course of the disease in subjects with deficiency of A1AT. PMID- 27689756 TI - Evaluation of antidepressant-like and anxiolytic-like activity of purinedione derivatives with affinity for adenosine A2A receptors in mice. AB - BACKGROUND: It has recently been suggested that the adenosine A2A receptor plays a role in several animal models of depression. Additionally, A2A antagonists have reversed behavioral deficits and exhibited a profile similar to classical antidepressants. METHODS: In the present study, imidazo- and pyrimido[2,1 f]purinedione derivatives (KD 66, KD 167, KD 206) with affinity to A2A receptors but poor A1 affinity were evaluated for their antidepressant- and anxiolytic-like activity. The activity of these derivatives was tested using a tail suspension and forced swim test, two widely-used behavioral paradigms for the evaluation of antidepressant-like activity. In turn, the anxiolytic activity was evaluated using the four-plate test. RESULTS: The results showed the antidepressant-like activity of pyrimido- and imidazopurinedione derivatives (i.e. KD 66, KD 167 and KD 206) in acute and chronic behavioral tests in mice. KD 66 revealed an anxiolytic-like effect, while KD 167 increased anxiety behaviors. KD 206 had no effect on anxiety. Furthermore, none of the tested compounds increased locomotor activity. CONCLUSION: Available data support the proposition that the examined compounds with adenosine A2A receptor affinity may be an interesting target for the development of antidepressant and/or anxiolytic agents.

AB - In quantum electrodynamics, matter can be hybridized to confined optical fields by a process known as light-matter strong coupling. This gives rise to new hybrid light-matter states and energy levels in the coupled material, leading to modified physical and chemical properties. Here, we report for the first time the strong coupling of vibrational modes of proteins with the vacuum field of a Fabry Perot mid-infrared cavity. For two model systems, poly(l-glutamic acid) and bovine serum albumin, strong coupling is confirmed by the anticrossing in the dispersion curve, the square root dependence on the concentration, and a vacuum Rabi splitting that is larger than the cavity and vibration line widths. These results demonstrate that strong coupling can be applied to the study of proteins with many possible applications including the elucidation of the role of vibrational dynamics in enzyme catalysis and in H/D exchange experiments. PMID- 27689757 TI - Mechanisms underlying the hyperalgesic responses triggered by joint activation of TLR4. AB - BACKGROUND: Toll-like receptors (TLRs) including TLR4 and their signal pathways contribute to the pathogenesis of arthritis. Herein, we evaluated the mechanisms underlying the hyperalgesic response caused by TLR4 activation in the tibio tarsal joint in mice. METHODS: Joint inflammatory hyperalgesia was induced by intra-articular (ia) injection of LPS (lipopolysaccharide- TLR4 agonist) in C57BL/6, TLR4, TLR2, MyD88, TRIF, TNFR1/2 and IL-1R1 knockout (-/-) mice. Joint hyperalgesia was evaluated using an electronic von Frey. Neutrophil recruitment was assessed by MPO activity. Joint levels of cytokines were measured by ELISA. RESULTS: Firstly, it was shown that LPS injected into the joints causes a dose- and time-dependent reduction in the mechanical nociceptive threshold. The TLR4 activation in the joint triggers mechanical hyperalgesia and neutrophil migration, which was abolished in TLR4 -/- and MyD88-/-, but not in TLR2-/- and TRIF-/- mice. Besides, joint administration of LPS increased the release of TNF alpha, IL-1beta, and KC/CXCL1, which were reduced in TLR4-/- and MyD88-/-, but not in TRIF-/- mice. In agreement, the LPS-induced joint nociceptive effect was decreased in TNFR1/2-/- and IL-1R1-/- mice or in mice pre-treated with a CXCR1/2 selective antagonist (DF2156A). CONCLUSIONS: These results suggest that TLR4 activation in the joint produces articular hyperalgesia via MyD88 signaling pathway. Moreover, this pathway is involved in the cascade of events of articular hyperalgesia through mechanisms dependent on cytokines and chemokines production. Thus, TLR4/MyD88 signaling pathway inhibitors might be useful for the treatment of inflammatory joint pain. PMID- 27689760 TI - Complications, Readmissions, and Reoperations in Posterior Cervical Fusion. AB - STUDY DESIGN: Retrospective cohort study of the American College of Surgeons National Surgical Quality Improvement Program database from 2011 to 2012. OBJECTIVE: Minimizing the morbidity of posterior cervical fusion can be improved with identification of patient risk factors. SUMMARY OF BACKGROUND DATA: Posterior cervical fusion is an effective technique for treating a variety of pathology. Stability and neurological improvement have been well documented. The increasing frequency of these procedures necessitates further investigation into the factors that may negatively impact perioperative care. METHODS: The American College of Surgeons National Surgical Quality Improvement Program was queried for all patients undergoing posterior cervical fusion in 2011 and 2012. Preoperative and intraoperative variables were investigated for correlation to complications, readmissions, prolonged intubation, reintubation, and reoperation. A frailty based score was used to assess preoperative risk. Regression models for prediction were performed. RESULTS: The study identified 5627 patients of posterior cervical fusion in 2011 and 2012. Of these, 2029 patients (36.1%) had any of our identified complications. Transfusion was the most common in 1482 (26.3%) patients. Excluding transfusion, the complication rate was 9.8%. Prolonged intubation greater than 48 hours occurred in 83 (1.5%) patients. Reintubation occurred in 72 (1.3%) patients. Readmission occurred in 398 (7.8%) patients. Reoperation was necessary in 273 (4.9%) patients with postoperative infection being the most common reason. The frailty-based score was shown to be predictive of any of the above events (P < 0.0001). The majority of patients (54.9%) in the group that had complications was found to have a frailty score of 1 or higher. CONCLUSION: The predictors for any event included female sex, increased surgical time, combined anterior-posterior procedures, preoperative inpatient status, diabetes, smoking, American Society of Anesthesiologists class 3 or higher, and increasing age. The frailty-based score is a viable option to predict morbidity in posterior cervical fusion. LEVEL OF EVIDENCE: 3. PMID- 27689761 TI - Is There an Association of Epidural Corticosteroid Injection With Postoperative Surgical Site Infection After Surgery for Lumbar Degenerative Spine Disease? AB - STUDY DESIGN: Retrospective study. OBJECTIVE: To assess the relation between exposure to epidural steroid injection (ESI) before surgery and occurrence of surgical site infection (SSI) for degenerative lumbar spine conditions. SUMMARY OF BACKGROUND DATA: The effect of local ESI on the occurrence of SSI is controversial. METHODS: Patients who underwent surgery for degenerative lumbar spine conditions at two centers between 2005 and 2015 were identified. Primary outcome measure was SSI within 90 days requiring surgical intervention. RESULTS: A total of 5311 patients (age 57 +/- 16 years) were analyzed of which 945 (18%) had at least one ESI within 90 days of surgery. One hundred thirty-four (2.5%) patients developed an SSI requiring reoperation. No association of exposure or dose-response relationship was identified between ESI and SSI for any of the time periods (90-, 30-, and 30-90-day). Five (1.7%) of the 290 patients who had at least one ESI within 30 days before surgery had a postoperative infection compared to 129 (2.6%) of the 5021 in the non-ESI group (unadjusted odds ratio: 0.67, 95% CI: 0.27-1.64, P = 0.376). Fifteen (2.0%) of the 761 patients who had at least one ESI within 30 to 90 days before surgery had a postoperative infection, compared to 119 (2.6%) of the 4550 in the non-ESI group (unadjusted odds ratio: 0.75, 95% CI: 0.44-1.29, P = 0.296). CONCLUSION: In this retrospective study we investigated whether an ESI and its timing influences the postoperative risk of an SSI. We found no association-exposure or dose-response relationship-between ESI and postoperative infection, even after adjusting for potential confounders, for any of the time periods (90-, 30-, and 30-90-day ESI). In addition, we did find that longer hospital stay, greater EBL, posterior approach, and drain placement were associated with higher infection rates. LEVEL OF EVIDENCE: 3. PMID- 27689762 TI - Remodeling of the Cervical Facet Joint After Minimally Invasive Microendoscopic Resection for Cervical Osteoid Osteoma. AB - STUDY DESIGN: Case report and systematic review of the literature. OBJECTIVE: To describe a rare case of remodeling of the cervical facet joint after the microendoscopic resection of an osteoid osteoma. SUMMARY OF BACKGROUND DATA: Osteoid osteoma, the third most common benign bone tumor, is often treated by image-guided percutaneous removal of the nidus. However, percutaneous resection poses technical difficulties when the tumor is located near the spinal cord or nerve roots. To our knowledge, there are no reports describing postoperative remodeling of the cervical facet joint after surgical resection of an osteoid osteoma. METHODS: A 13-year-old boy was presented with neck pain that became worse at night. Computed tomography showed an osteoid osteoma in the right 7th cervical superior articular process. We successfully resected the nidus of the osteoid osteoma using minimally invasive microendoscopy. RESULTS: The patient was symptom-free at the 1-year follow up, and computed tomography images showed new bone formation at the C6/7 facet joint. CONCLUSION: This case indicates that microendoscopic resection is safe and effective for treating a cervical osteoid osteoma. This technique allowed total resection of the nidus with only minimal damage to the adjacent soft tissue and bone, and induced remodeling of the resection site. LEVEL OF EVIDENCE: 4.

AB - Synthesis and novel applications of biofunctional polymers for diagnosis and therapy are promising area involving various research domains. Herein, three fluorescent polymers, poly(p-phenylene-co-thiophene), poly(p-phenylene), and polythiophene with amino groups (PPT-NH2 , PPP-NH2 , and PT-NH2 , respectively) are synthesized and investigated for cancer cell targeted imaging, drug delivery, and radiotherapy. Polymers are conjugated to anti-HER2 antibody for targeted imaging studies in nontoxic concentrations. Three cell lines (A549, Vero, and HeLa) with different expression levels of HER2 are used. In a model of HER2 expressing cell line (A549), radiotherapy experiments are carried out and results show that all three polymers increase the efficacy of radiotherapy. This effect is even more increased when conjugated to anti-HER2. In the second part of this work, one of the selected polymers (PT-NH2 ) is conjugated with a drug model; methotrexate via pH responsive hydrazone linkage and a drug carrier property of PT-NH2 is demonstrated on neuroblastoma (SH-SY5Y) cell model. Our results indicate that, PPT-NH2 , PPP-NH2 , and PT-NH2 have a great potential as biomaterials for various bioapplications in cancer research. PMID- 27689765 TI - Increased lipogenesis in spite of upregulated hepatic 5'AMP-activated protein kinase in human non-alcoholic fatty liver. AB - AIMS: Molecular adaptations in human non-alcoholic fatty liver disease (NAFLD) are incompletely understood. This study investigated the main gene categories related to hepatic de novo lipogenesis and lipid oxidation capacity. METHODS: Liver specimens of 48 subjects were histologically classified according to steatosis severity. In-depth analyses were undertaken using real-time polymerase chain reaction, immunoblotting, and immunohistochemistry. Lipid profiles were analyzed by gas chromatography/flame ionization detection, and effects of key fatty acids were studied in primary human hepatocytes. RESULTS: Real-time polymerase chain reaction, immunoblotting, and immunohistochemistry indicated 5'AMP-activated protein kinase (AMPK) to be increased with steatosis score >= 2 (all P < 0.05), including various markers of de novo lipogenesis and lipid degradation (all P < 0.05). Regarding endoplasmic reticulum stress, X-Box binding protein-1 (XBP1) was upregulated in steatosis score >= 2 (P = 0.029) and correlated with plasma palmitate (r = 0.34; P = 0.035). Palmitate incubation of primary human hepatocytes increased XBP1 and downstream stearoyl CoA desaturase-1 mRNA expression (both P < 0.05). Moreover, plasma and liver tissue exposed a NAFLD-related lipid profile with reduced polyunsaturated/saturated fatty acid ratio, increased palmitate and palmitoleate, and elevated lipogenesis and desaturation indices with steatosis score >= 2 (all P < 0.05). CONCLUSION: In humans with advanced fatty liver disease, hepatic AMPK protein is upregulated, potentially in a compensatory manner. Moreover, pathways of lipid synthesis and degradation are co-activated in subjects with advanced steatosis. Palmitate may drive lipogenesis by activating XBP1-mediated endoplasmic reticulum stress and represent a target for future dietary or pharmacological intervention. PMID- 27689766 TI - The ABCs of flower development: mutational analysis of AP1/FUL-like genes in rice provides evidence for a homeotic (A)-function in grasses. AB - The well-known ABC model describes the combinatorial interaction of homeotic genes in specifying floral organ identities. While the B- and C-functions are highly conserved throughout flowering plants and even in gymnosperms, the A function, which specifies the identity of perianth organs (sepals and petals in eudicots), remains controversial. One reason for this is that in most plants that have been investigated thus far, with Arabidopsis being a remarkable exception, one does not find recessive mutants in which the identity of both types of perianth organs is affected. Here we report a comprehensive mutational analysis of all four members of the AP1/FUL-like subfamily of MADS-box genes in rice (Oryza sativa). We demonstrate that OsMADS14 and OsMADS15, in addition to their function of specifying meristem identity, are also required to specify palea and lodicule identities. Because these two grass-specific organs are very likely homologous to sepals and petals of eudicots, respectively, we conclude that there is a floral homeotic (A)-function in rice as defined previously. Together with other recent findings, our data suggest that AP1/FUL-like genes were independently recruited to fulfil the (A)-function in grasses and some eudicots, even though other scenarios cannot be excluded and are discussed.

PMID- 27689769 TI - Microcomputed Tomography Evaluation of Polymerization Shrinkage of Class I Flowable Resin Composite Restorations. AB - The present study aimed to characterize the pattern and volume of polymerization shrinkage of flowable resin composites, including one conventional, two bulk fill, and one self-adhesive. Standardized class I preparations (2.5 mm depth * 4 mm length * 4 mm wide) were performed in 24 caries-free human third molars that were randomly divided in four groups, according to the resin composite and adhesive system used: group 1 = Permaflo + Peak Universal Bond (PP); group 2 = Filtek Bulk Fill + Scotchbond Universal (FS); group 3 = Surefil SDR + XP Bond (SX); and group 4 = Vertise flow self-adhering (VE) (n=6). Each tooth was scanned three times using a microcomputed tomography (MUCT) apparatus. The first scan was done after the cavity preparation, the second after cavity filling with the flowable resin composite before curing, and the third after it was cured. The MUCT images were imported into three-dimensional rendering software, and volumetric polymerization shrinkage percentage was calculated for each sample. Data were submitted to one-way analysis of variance and post hoc comparisons. No significant difference was observed among PP, FS, and VE. SX bulk fill resin composite presented the lowest values of volumetric shrinkage. Shrinkage was mostly observed along the occlusal surface and part of the pulpal floor. In conclusion, polymerization shrinkage outcomes in a 2.5-mm deep class I cavity were material dependent, although most materials did not differ. The location of shrinkage was mainly at the occlusal surface.

METHODS AND MATERIALS: Two types of CAD/CAM blocks (Cerasmart, GC; Enamic, Vita Zahnfabrik) were cut in slabs of 4-mm thickness, divided into six groups, and subjected to the following surface treatments: group 1: no treatment; group 2: sandblasting (SB); group 3: SB + silane (Si); group 4: SB + Si + flowable composite (see below); group 5: 5% hydrofluoric acid etching (HF) + Si; and group 6: 37% phosphoric acid etching (H3PO4) + Si. Sections of the same group were luted together (n=3: 3 sandwich specimens/group) using a dual cure self-adhesive cement for all groups, except for the sections of group 4 that were luted using a light-curing flowable composite. After three weeks of storage in 0.5% chloramine at 37 degrees C, the sandwich specimens were sectioned in rectangular microspecimens and trimmed at the interface to a dumbbell shape (1.1 mm diameter). One half of the specimens was subjected to a microtensile bond strength (MUTBS) test, and the other half was tested after six months of water storage (aging). Data were statistically analyzed with a linear mixed-effects model for the factors surface treatment, material type, and aging, together with their first-degree interactions (alpha=0.05). RESULTS: The lowest bond strengths were obtained in the absence of any surface treatment (group 1), while the highest MUTBSs were obtained when the surface was roughened by either SB or HF, this in combination with chemical adhesion through Si. Loss in bond strength was observed after six-month aging when either surface roughening or silanization, or both, were omitted. CONCLUSIONS: Both the composite and polymer-infiltrated ceramic CAD/CAM blocks appeared equally bonding-receptive regardless of the surface treatment used. Creating a microretentive surface by either SB or HF, followed by chemical adhesion using Si, is mandatory to maintain the bond strength after six months.

AB - OBJECTIVES: The purpose of this study was to investigate the influence of insufficient light exposure on the polymerization of conventional and self adhesive dual-cure resin cements under ceramic restorations. METHODS: Two conventional dual-cure resin cements (Rely-X ARC, Duolink) and two self-adhesive resin cements (Rely-X U200, Maxcem Elite) were polymerized under different curing modes (dual-cure or self-cure), curing times (20 and 120 seconds), and thickness of a ceramic overlay (2 and 4 mm). Polymerization kinetics was measured by Fourier transform infrared spectroscopy for the initial 10 minutes and after 24 hours. Data were analyzed using mixed model analysis of variance (ANOVA), one-way ANOVA/Student-Newman-Keuls post hoc test, and paired t-test (alpha=0.05). RESULTS: When light-curing time was set to 20 seconds, the presence of the ceramic block significantly affected the degree of conversion (DC) of all resin cements. Especially, the DC of the groups with 20 seconds of light-curing time under 4 mm of ceramic thickness was even lower than that of the self-cured groups at 24 hours after polymerization (p<0.05). However, when light-curing time was set to 120 seconds, a similar DC compared with the group with direct light exposure (p>0.05) was achieved in all dual-cure groups except Maxcem Elite, at 24 hours after polymerization. CONCLUSIONS: For both conventional and self-adhesive dual-cure resin cements, insufficient light exposure (20 seconds of light-curing time) through thick ceramic restoration (4 mm thick) resulted in a DC even lower than that of self-curing alone. PMID- 27689772 TI - Effect of Nd:YAG Laser Irradiation Pretreatment on the Long-Term Bond Strength of Etch-and-Rinse Adhesive to Dentin. AB - PURPOSE: To investigate the effect of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser irradiation pretreatment on the long-term bond strength of an etch and-rinse adhesive to dentin. METHODS: Fifty molars were sectioned parallel to the occlusal plane and randomly divided into two groups (n=25 per group): control group (no treatment) and laser group (dentin surfaces were treated with Nd:YAG laser at a setting of 100 mJ/10 Hz). Afterward, resin was bonded to the dentin surface using a two-step etch-and-rinse adhesive (Adper SingleBond 2), and then 150 beams of each group were produced. Each group was divided into three subgroups (n=50 each group): 24 hours of water storage, thermocycling, and NaOCl storage. The microtensile bond strength (MTBS), failure modes, nanoleakage expression, and Masson's trichrome staining were evaluated. An additional 20 molars were sectioned to obtain 2-mm-thick flat dentin slices. These slices were randomly divided into control and laser-treated groups as mentioned previously. Then slices of each group were examined by scanning electron microscopy, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), X ray diffraction (XRD), and the Knoop hardness test. RESULTS: The results of ATR FTIR and Masson's trichrome verified that laser irradiation partly removed collagen fibers from the dentin surface; however, no significant difference was found in the Knoop hardness (p>0.05). The XRD result showed similar crystalline structure regardless of laser pretreatment. There is no significant difference in short-term MTBS between control and laser-treated groups (p>0.05); however, long term MTBS differed between the groups (p>0.05). Furthermore, the laser-treated group showed less silver deposition than the control group after aging (p<0.05). CONCLUSION: Pretreatment by Nd:YAG laser irradiation appeared to have a positive effect on the adhesive-dentin bonding in vitro test, and the bonding effectiveness could be preserved after aging.

AB - AIM: To investigate the response of immature permanent teeth with nonvital pulps after revitalization procedures using cone beam computed tomography imaging and conventional radiograph. METHODOLOGY: Clinical records of patients who had undergone revitalization between 1997 and 2014 were collected. Seventeen patients attended the follow-up examination. Clinical examination and radiographic examination by means of CBCT imaging and conventional radiographs were conducted to evaluate treatment outcomes, especially the dimensional changes of the root and the pattern of root maturation. Statistical analysis was conducted using Fisher's exact test and Monte Carlo test to investigate the effect of potential outcome predictors. RESULTS: For the follow-up period as far as 96 months, thirteen teeth (76%) were classified as a 'success'. Conventional radiographs showed various degrees of dimensional changes in the immature roots ranging from 0% to 73% changes. The mean percentage changes of root length and root wall thickness were 14.38 +/- 20.92% and 13.82 +/- 11.17%, respectively. CBCT images illustrated various patterns of root maturation including incomplete root development with wide-open apices and fully formed roots with various apical shapes. Root canal contents varied radiographically from empty canals to many degrees of unpredictable patterning of radiopaque deposits. CONCLUSION: Revitalization in immature teeth with nonvital pulps resulted in unpredictable responses in terms of continued root development. Various types of root maturation and root canal contents were observed radiographically, which were different from typical root development. PMID- 27689774 TI - Impact of Nonthermal Atmospheric Plasma on the Structure of Cellulose: Access to Soluble Branched Glucans. AB - We have investigated the effect of non-thermal atmospheric plasma (NTAP) on the structure of microcrystalline cellulose. In particular, by means of different characterization methods, we demonstrate that NTAP promotes the partial cleavage of the beta-1,4 glycosidic bond of cellulose leading to the release of short chain cellodextrins that are reassembled in situ, preferentially at the C6 position, to form branched glucans with either a glucosyl or anhydroglucosyl terminal residue. The ramification of cellulosic chain induced by NTAP yields branched glucans that are soluble in DMSO or in water, thus opening a straightforward access to processable glucans from cellulose. Importantly, the absence of solvent and catalyst considerably facilitates downstream processing as compared to (bio)catalytic processes which typically occur in diluted conditions. PMID- 27689775 TI - Probing Membrane Viscosity and Interleaflet Friction of Supported Lipid Bilayers by Tracking Electrostatically Adsorbed, Nano-Sized Vesicles. AB - Particle tracking is used to measure the diffusional motion of nanosized (~100 nm), lipid vesicles that are electrostatically adsorbed onto a solid supported lipid bilayer. It is found that the motion of membrane-adhering vesicles is Brownian and depends inversely on the vesicle size, but is insensitive to the vesicle surface charge. The measured diffusivity agrees well with the Evans Sackmann model for the diffusion of inclusions in supported, fluidic membranes. The agreement implies that the vesicle motion is coupled to that of a nanoscopic lipid cluster in the upper leaflet, which slides over the lower leaflet. The diffusivity of membrane-adhering vesicles is therefore predominantly governed by the interleaflet friction coefficient, while the diffusivity of single lipids is mainly governed by the membrane viscosity. Combined with fluorescence recovery after photobleaching analysis, the interleaflet friction coefficient and the membrane viscosity are determined by applying the Evans-Sackmann model to the measured diffusivity of membrane adhering vesicles and that of supported membrane lipids. This approach provides an alternative to existing methods for measuring the interleaflet friction coefficient and the membrane viscosity.

AB - A highly enantioselective synthesis of indolines by asymmetric hydrogenation of 1H-indoles and 3H-indoles at ambient temperature and pressure, catalyzed by chiral phosphine-free cationic ruthenium complexes, has been developed. Excellent enantio- and diastereoselectivities (up to >99 % ee, >20:1 d.r.) were obtained for a wide range of indole derivatives, including unprotected 2-substituted and 2,3-disubstituted 1H-indoles, as well as 2-alkyl- and 2-aryl-substituted 3H indoles. PMID- 27689777 TI - Gas chromatography/mass spectrometry measurement of xenon in gas-loaded liposomes for neuroprotective applications. AB - RATIONALE: We have produced a liposomal formulation of xenon (Xe-ELIP) as a neuroprotectant for inhibition of brain damage in stroke patients. This mandates development of a reliable assay to measure the amount of dissolved xenon released from Xe-ELIP in water and blood samples. METHODS: Gas chromatography/mass spectrometry (GC/MS) was used to quantify xenon gas released into the headspace of vials containing Xe-ELIP samples in water or blood. In order to determine blood concentration of xenon in vivo after Xe-ELIP administration, 6 mg of Xe ELIP lipid was infused intravenously into rats. Blood samples were drawn directly from a catheterized right carotid artery. After introduction of the samples, each vial was allowed to equilibrate to 37 degrees C in a water bath, followed by 20 minutes of sonication prior to headspace sampling. Xenon concentrations were calculated from a gas dose-response curve and normalized using the published xenon water-gas solubility coefficient. RESULTS: The mean corrected percent of xenon from Xe-ELIP released into water was 3.87 +/- 0.56% (SD, n = 8), corresponding to 19.3 +/- 2.8 MUL/mg lipid, which is consistent with previous independent Xe-ELIP measurements. The corresponding xenon content of Xe-ELIP in rat blood was 23.38 +/- 7.36 MUL/mg lipid (n = 8). Mean rat blood xenon concentration after intravenous administration of Xe-ELIP was 14 +/- 10 MUM, which is approximately 15% of the estimated neuroprotective level. CONCLUSIONS: Using this approach, we have established a reproducible method for measuring dissolved xenon in fluids. These measurements have established that neuroprotective effects can be elicited by less than 20% of the calculated neuroprotective xenon blood concentration. More work will have to be done to establish the protective xenon pharmacokinetic range. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - AIM: This study compared obstetric units practicing routine or selective umbilical cord blood gas analysis, with respect to the risk of missing samples in high-risk deliveries and in infants with birth asphyxia. METHODS: This was a Swedish population-based cohort study that used register data for 155 235 deliveries of live singleton infants between 2008 and 2014. Risk ratios and 95% confidence intervals were calculated to estimate the association between routine and selective umbilical cord blood gas sampling strategies and the risk of missing samples. RESULTS: Selective sampling increased the risk ratios when routine sampling was used as the reference, with a value of 1.0, and these were significant in high-risk deliveries and birth asphyxia. The risk ratios for selective sampling were large-for-gestational age (9.07), preterm delivery at up to 36 weeks of gestation (8.24), small-for-gestational age (7.94), two or more foetal scalp blood samples (5.96), an Apgar score of less than seven at one minute (2.36), emergency Caesarean section (1.67) and instrumental vaginal delivery (1.24). CONCLUSION: Compared with routine sampling, selective umbilical cord blood gas sampling significantly increased the risks of missing samples in high-risk deliveries and in infants with birth asphyxia.

AB - Cardiac tissue engineering (CTE) is currently a prime focus of research because of an enormous clinical need. In the present work, a novel functional material, poly(3-hydroxyoctanoate), P(3HO), a medium chain-length polyhydroxyalkanoate (PHA), produced using bacterial fermentation, was studied as a new potential material for CTE. Engineered constructs with improved mechanical properties, crucial for supporting the organ during new tissue regeneration, and enhanced surface topography, to allow efficient cell adhesion and proliferation, were fabricated. Results showed that the mechanical properties of the final patches were close to that of cardiac muscle. Biocompatibility of neat P(3HO) patches, assessed using neonatal ventricular rat myocytes (NVRM), showed that the polymer was as good as collagen in terms of cell viability, proliferation and adhesion. Enhanced cell adhesion and proliferation properties were observed when porous and fibrous structures were incorporated into the patches. In addition, no deleterious effect was observed on adult cardiomyocyte contraction when cardiomyocytes were seeded on the P(3HO) patches. Hence, P(3HO)-based multifunctional cardiac patches are promising constructs for efficient CTE. This work will have a positive impact on the development of P(3HO) and other PHAs as a novel new family of biodegradable functional materials with huge potential in a range of different biomedical applications, particularly CTE, leading to further interest and exploitation of these materials.

AB - Infrastructure development of volatile regions is a significant investment by international government and nongovernment organizations, with attendant requirements for risk management. Global development banks may be tasked to manage these investments and provide a channel between donors and borrowers. Moreover, various stakeholders from the private sector, local and international agencies, and the military can be engaged in conception, planning, and implementation of constituent projects. Emergent and future conditions of military conflict, politics, economics, technology, environment, behaviors, institutions, and society that stress infrastructure development are prevalent, and funding mechanisms are vulnerable to fraud, waste, and abuse. This article will apply resilience analytics with scenario-based preferences to identify the stressors that most influence a prioritization of initiatives in the electric power sector of Afghanistan. The resilience in this article is conceived in terms of the degree of disruption of priorities when stressors influence the preferences of stakeholders, and ultimately a prioritization of initiatives. The ancillary results include an understanding of which initiatives contribute most and least across strategic criteria and which criteria have the most impact for the analysis. The article concludes with recommendations for risk monitoring and risk management of the portfolio of stressors through the life cycle and horizon of grid capacity expansion. PMID- 27689784 TI - The Proteolytic Activity of Porphyromonas gingivalis Is Critical in a Murine Model of Periodontitis. AB - BACKGROUND: Porphyromonas gingivalis (Pg), a periodontal pathogen, has interstrain variability in virulence. The aim of this study is to determine the contribution of the cell invasion ability and proteolytic activity of Pg to its virulence in a murine model of periodontitis. METHODS: Three clinical isolates: KUMC-P1 (P1: low cell invasion ability and low proteolytic activity); KUMC-P4 (P4: low cell invasion ability and high proteolytic activity); and KUMC-P8 (P8: high cell invasion ability and low proteolytic activity), were orally administered into mice. Alveolar bone loss (ABL) and bacterial invasion of gingival tissues were measured. Additionally, effects of the three strains on transepithelial electrical resistance (TER) and the levels of tight-junction proteins in gingival epithelial cells were evaluated in vitro. RESULTS: ABL induced by the three strains was in the sequence P4 > P8 > P1, and the difference between P8 and P1 was not significant. Amounts of Pg detected within the gingival tissues were increased by all three strains compared with the sham group, and bacterial level was positively correlated with ABL. In vitro, P4 had a greater effect than the other strains on epithelial barrier disruption, as evidenced by the reduced levels of tight-junction proteins and TER. CONCLUSION: The proteolytic activity of Pg was more critical than the cell invasion ability for inducing experimental periodontitis in mice, which could be attributed to the paracellular pathway dependence of gingival tissue invasion by bacteria in the mice. PMID- 27689785 TI - Methionine sulfoximine supplementation enhances productivity in GS-CHOK1SV cell lines through glutathione biosynthesis. AB - In Lonza Biologics' GS Gene Expression SystemTM, recombinant protein-producing GS CHOK1SV cell lines are generated by transfection with an expression vector encoding both GS and the protein product genes followed by selection in MSX and glutamine-free medium. MSX is required to inhibit endogenous CHOK1SV GS, and in effect create a glutamine auxotrophy in the host that can be complemented by the expression vector encoded GS in selected cell lines. However, MSX is not a specific inhibitor of GS as it also inhibits the activity of GCL (a key enzyme in the glutathione biosynthesis pathway) to a similar extent. Glutathione species (GSH and GSSG) have been shown to provide both oxidizing and reducing equivalents to ER-resident oxidoreductases, raising the possibility that selection for transfectants with increased GCL expression could result in the isolation of GS CHOKISV cell lines with improved capacity for recombinant protein production. In this study we have begun to address the relationship between MSX supplementation, the amount of intracellular GCL subunit and mAb production from a panel of GS CHOK1SV cell lines. We then evaluated the influence of reduced GCL activity on batch culture of an industrially relevant mAb-producing GS-CHOK1SV cell line. To the best of our knowledge, this paper describes for the first time the change in expression of GCL subunits and recombinant mAb production in these cell lines with the degree of MSX supplementation in routine subculture. Our data also shows that partial inhibition of GCL activity in medium containing 75 uM MSX increases mAb productivity, and its more specific inhibitor BSO used at a concentration of 80 uM in medium increases the specific rate of mAb production eight-fold and the concentration in harvest medium by two-fold. These findings support a link between the inhibition of glutathione biosynthesis and recombinant protein production in industrially relevant systems and provide a process-driven method for increasing mAb productivity from GS-CHOK1SV cell lines.

PMID- 27689786 TI - Health promotion and information provision during long-term follow-up for childhood cancer survivors: A service evaluation. AB - Health promotion is an important component of long-term follow-up (LTFU) care for childhood cancer survivors (CCS). However, little information exists about how survivors perceive their own health promotion needs. As part of a service evaluation, 51 CCS who had previously attended the LTFU clinic took part in a single semistructured interview to seek their views on information they had received regarding late adverse effects (LAEs) of treatment, the purpose of LTFU, and the provision of health promotion information. Although most (93%) CCS were satisfied with the information received about LAEs, 37% desired further details. Over half (59%) believed that the purpose of LTFU was to screen for LAEs, whereas 31% felt that it was to check for relapse. No survivor reported health promotion to be an aim of LTFU; only 14% of CCS expected to receive healthy lifestyle advice, and fewer than 10% wanted dietary and physical activity advice. Most (88%) CCS felt that their hospital-based health care professional was best placed to give healthy lifestyle advice, but there was no consensus about the optimum timing for health promotion. CCS varied in their knowledge, needs, and wishes regarding LTFU care. The results of this evaluation strongly indicate that the profile of health promotion needs to be raised within our service and identifies issues that may be pertinent to similar services. Further research is needed to understand the views of CCS regarding health promotion and lifestyle behaviors, with the aim of tailoring and improving the delivery of effective health education to CCS.

PMID- 27689788 TI - Experiences of therapeutic relationships on hospital wards, dissociation, and making connections. AB - An interpretive phenomenological analysis sought to explore how people reporting moderate to high levels of dissociation experienced relationships with multidisciplinary hospital ward staff. Three superordinate themes were developed. First, the theme "multiple me and multiple them" explores the instability experienced by the participants as they managed their dissociative experiences alongside many inconsistencies. Second, "recognizing, meeting, or neglecting interpersonal and care needs" reflects on participants' needs within therapeutic relationships. Third, "between the needs of the internal system: navigating between 'better on my own' and 'someone to talk to'" discusses the confusion and understanding around dissociation and the importance of working with parts, not around them. Findings suggested that the current culture of some hospital wards directly influenced participants' distress, which could lead to further dissociation as a means of coping with perceived threats. Reflections on relational complexities and developing ward-based treatment are discussed.

AB - We aimed to evaluate the feasibility of robot-assisted rehabilitation in an early postoperative setting to improve knee mobility following total knee arthroplasty (TKA). A total of 20 patients were alternatively assigned to robotassisted rehabilitation (n = 10; all women) or a control group (n = 10; 2 men and 8 women). The use of a single-joint hybrid assistive limb (HAL-SJ) in active assistive knee exercise was performed for the robot-assisted rehabilitation group while the control patients underwent conventional active assistive knee exercise. We measured the extension lag (defined as the difference between active and passive range of knee extension). We also evaluated the visual analog scale score (VAS) during active movements and active assistive movement. Concerning the extension lag, the robot-assisted rehabilitation group showed 89.4% +/- 15.7% improvement (p < 0.01) while the control group showed 34.8% +/- 32.1% improvement (p = 0.016). As to the VAS, the robot-assisted rehabilitation group showed 40.7% +/- 23.5% improvement while the control group showed 20.4% +/- 25.8% improvement (p < 0.01). The use of HAL-SJ may facilitate early recovery from knee surgery and prevent long-term complications such as quadriceps arthrogenic muscle inhibition.

This experiment investigates effects of the ratio of carboxymethyl chitosan and collagen blend, water to oil ratio, stirring speed, and other factors on the microsphere properties. The experiment had the following conditions: a 1:2 proportion of carboxymethyl chitosan and collagen, a 1:2 proportion of drugs and materials, a 5:1 proportion of oil phase and water phase, 0.5% of span80, a 600r/min stirring speed, 3 ml of a cross-linking agent, 3 h of cross-linking curing, 1.25 +/- 0.05 mm diameter LTH microcapsules, a 54.08% envelop rate, and a 14.16% carrier rate. The microspheres release rate reached 66% within 1 h, then steadily released within 5 h in vitro. The experimental results showed that the ligustrazine hydrochloride microsphere production process was stable and exhibited a good release effect compared with other ligustrazine hydrochloride tablets and pills.

AB - Recent studies have reported that exposure of mammalian cells to microwave radiation may have adverse effects such as induction of cell apoptosis. However, the molecular mechanisms underlying microwave induced mammalian cell apoptosis are not fully understood. Here, we report a novel mechanism: exposure to 1800MHz microwave radiation induces p53-dependent cell apoptosis through cytochrome c mediated caspase-3 activation pathway. We first measured intensity of microwave radiation from several electronic devices with an irradiation detector. Mouse NIH/3T3 and human U-87 MG cells were then used as receivers of 1800MHz electromagnetic radiation (EMR) at a power density of 1209 mW/m2. Following EMR exposure, cells were analyzed for viability, intracellular reactive oxygen species (ROS) generation, DNA damage, p53 expression, and caspase-3 activity. Our analysis revealed that EMR exposure significantly decreased viability of NIH/3T3 and U-87 MG cells, and increased caspase-3 activity. ROS burst was observed at 6 h and 48 h in NIH/3T3 cells, while at 3 h in U-87 MG cells. Hoechst 33258 staining and in situ TUNEL assay detected that EMR exposure increased DNA damage, which was significantly restrained in the presence of N-acetyl-L-cysteine (NAC, an antioxidant). Moreover, EMR exposure increased the levels of p53 protein and p53 target gene expression, promoted cytochrome c release from mitochondrion, and increased caspase-3 activity. These events were inhibited by pretreatment with NAC, pifithrin-alpha (a p53 inhibitor) and caspase inhibitor. Collectively, our findings demonstrate, for the first time, that 1800MHz EMR induces apoptosis related events such as ROS burst and more oxidative DNA damage, which in turn promote p53-dependent caspase-3 activation through release of cytochrome c from mitochondrion. These findings thus provide new insights into physiological mechanisms underlying microwave-induced cell apoptosis. PMID- 27689799 TI - ATX-2, the C. elegans Ortholog of Human Ataxin-2, Regulates Centrosome Size and Microtubule Dynamics. AB - Centrosomes are critical sites for orchestrating microtubule dynamics, and exhibit dynamic changes in size during the cell cycle. As cells progress to mitosis, centrosomes recruit more microtubules (MT) to form mitotic bipolar spindles that ensure proper chromosome segregation. We report a new role for ATX 2, a C. elegans ortholog of Human Ataxin-2, in regulating centrosome size and MT dynamics. ATX-2, an RNA-binding protein, forms a complex with SZY-20 in an RNA independent fashion. Depleting ATX-2 results in embryonic lethality and cytokinesis failure, and restores centrosome duplication to zyg-1 mutants. In this pathway, SZY-20 promotes ATX-2 abundance, which inversely correlates with centrosome size. Centrosomes depleted of ATX-2 exhibit elevated levels of centrosome factors (ZYG-1, SPD-5, gamma-Tubulin), increasing MT nucleating activity but impeding MT growth. We show that ATX-2 influences MT behavior through gamma-Tubulin at the centrosome. Our data suggest that RNA-binding proteins play an active role in controlling MT dynamics and provide insight into the control of proper centrosome size and MT dynamics. PMID- 27689800 TI - Estimating Age-Specific Immunity and Force of Infection of Varicella Zoster Virus in Norway Using Mixture Models. AB - This study applies mixture modelling to examine age-specific immunity to varicella zoster virus (VZV) infection in Norway based on the first large-scale serological study in the general population. We estimated the seropositive proportions at different ages and calculated the underlying force of infection by using a sample of 2103 residual sera obtained from patients seeking primary and hospital care. A rapid increase in the VZV-associated immunity is observed in the first years of life with 63% of children being immune by age 5. The increase in the immunity levels slows down thereafter, with a large proportion of adults still susceptible by age 20 (around 14.5%), thus at risk of serious sequelae of varicella infection. The corresponding force of infection peaks during the preschool period, subsequently declines to a minimum between ages 10 and 20 years, and afterwards moderately increases to reach a plateau lasting throughout the childbearing period. In comparison with the traditional cut-off approach, mixture modelling used the whole data without producing any inconclusive cases, led to an unbiased classification of individuals between susceptible and immune, and provided a smoother immune profile by age. These findings represent an important step towards any decision about the introduction of varicella vaccination in Norway, as they are a primary input for mathematical transmission models aimed at evaluating potential vaccination scenarios. PMID- 27689801 TI - Antecolic versus retrocolic reconstruction after partial pancreaticoduodenectomy. AB - BACKGROUND: Pancreatic cancer remains one of the five leading causes of cancer deaths in industrialized nations. For adenocarcinomas in the head of the gland and premalignant lesions, partial pancreaticoduodenectomy represents the standard treatment for resectable tumours. The gastro- or duodenojejunostomy after partial pancreaticoduodenectomy can be reestablished via either an antecolic or a retrocolic route. The debate about the more favourable technique for bowel reconstruction is ongoing. OBJECTIVES: To compare the effectiveness and safety of antecolic and retrocolic gastro- or duodenojejunostomy after partial pancreaticoduodenectomy. SEARCH METHODS: We conducted a systematic literature search on 29 September 2015 to identify all randomised controlled trials in the Cochrane Central Register of Controlled Trials (CENTRAL), The Cochrane Library 2015, issue 9, MEDLINE (1946 to September 2015), and EMBASE (1974 to September 2015). We applied no language restrictions. We handsearched reference lists of identified trials to identify further relevant trials, and searched the trial registry clinicaltrials.gov for ongoing trials. SELECTION CRITERIA: We considered all randomised controlled trials that compared antecolic versus retrocolic reconstruction of bowel continuity after partial pancreaticoduodenectomy for any given indication to be eligible. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the identified references and extracted data from the included trials. The same two review authors independently assessed risk of bias of included trials, according to standard Cochrane methodology. We used a random effects model to pool the results of the individual trials in a meta-analysis. We used odds ratios to compare binary outcomes and mean differences for continuous outcomes. MAIN RESULTS: Of a total of 216 citations identified by the systematic literature search, we included six randomised controlled trials (reported in nine publications), with a total of 576 participants. We identified a moderate heterogeneity of methodological quality and risk of bias of the included trials. None of the pooled results for our main outcomes of interest showed significant differences: delayed gastric emptying (OR 0.60; 95% CI 0.31 to 1.18; P = 0.14), mortality (RD -0.01; 95% CI -0.03 to 0.02; P = 0.72), postoperative pancreatic fistula (OR 0.98; 95% CI 0.65 to 1.47; P = 0.92), postoperative haemorrhage (OR 0.79; 95% CI 0.38 to 1.65; P = 0.53), intra-abdominal abscess (OR 0.93; 95% CI 0.52 to 1.67; P = 0.82), bile leakage (OR 0.89; 95% CI 0.36 to 2.15; P = 0.79), reoperation rate (OR 0.59; 95% CI 0.27 to 1.31; P = 0.20), and length of hospital stay (MD -0.67; 95%CI -2.85 to 1.51; P = 0.55). Furthermore, the perioperative outcomes duration of operation, intraoperative blood loss and time to NGT removal showed no relevant differences. Only one trial reported quality of life, on a subgroup of participants, also without a significant difference between the two groups at any time point. The overall quality of the evidence was only low to moderate, due to heterogeneity, some inconsistency and risk of bias in the included trials. AUTHORS' CONCLUSIONS: There was low to moderate quality evidence suggesting no significant differences in morbidity, mortality, length of hospital stay, or quality of life between antecolic and retrocolic reconstruction routes for gastro- or duodenojejunostomy. Due to heterogeneity in definitions of the endpoints between trials, and differences in postoperative management, future research should be based on clearly defined endpoints and standardised perioperative management, to potentially elucidate differences between these two procedures. Novel strategies should be evaluated for prophylaxis and treatment of common complications, such as delayed gastric emptying.

AB - INTRODUCTION: Bacteria present in the apical root canal system are directly involved with the pathogenesis of post-treatment apical periodontitis. This study used a next-generation sequencing approach to identify the bacterial taxa occurring in cryopulverized apical root samples from root canal-treated teeth with post-treatment disease. METHODS: Apical root specimens obtained during periradicular surgery of ten adequately treated teeth with persistent apical periodontitis were cryogenically ground. DNA was extracted from the powder and the microbiome was characterized on the basis of the V4 hypervariable region of the 16S rRNA gene by using paired-end sequencing on Illumina MiSeq device. RESULTS: All samples were positive for the presence of bacterial DNA. Bacterial taxa were mapped to 11 phyla and 103 genera composed by 538 distinct operational taxonomic units (OTUs) at 3% of dissimilarity. Over 85% of the sequences belonged to 4 phyla: Proteobacteria, Firmicutes, Fusobacteria and Actinobacteria. In general, these 4 phyla accounted for approximately 80% of the distinct OTUs found in the apical root samples. Proteobacteria was the most abundant phylum in 6/10 samples. Fourteen genera had representatives identified in all cases. Overall, the genera Fusobacterium and Pseudomonas were the most dominant. Enterococcus was found in 4 cases, always in relatively low abundance. CONCLUSIONS: This study showed a highly complex bacterial community in the apical root canal system of adequately treated teeth with persistent apical periodontitis. This suggests that this disease is characterized by multispecies bacterial communities and has a heterogeneous etiology, because the community composition largely varied from case to case.

PMID- 27689806 TI - Antimicrobial Silver Nanoclusters Bearing Biocompatible Phosphorylcholine-Based Zwitterionic Protection. AB - Infection is one of the most serious issues in medical treatments leading to the development of several antimicrobial agents. In particular, silver ions released from silver substrates is well-known as a reliable antimicrobial agent that either kills the microorganisms or inhibits their growth. Unfortunately, many reports have shown that silver-based antimicrobial agents are toxic for human cells as well. To improve the biocompatibility of silver antimicrobial agents, we have synthesized thiol-terminated phosphorylcholine (PC-SH)-protected silver nanoclusters (PC-AgNCs) via strong thiol-metal coordination with controlled ultrasmall size of the clusters. A change in plasmon-like optical absorption was studied to affirm the successful synthesis of small thiolated AgNCs through the absorption spectra that become molecular-like for the AgNCs. We observed that PC AgNCs were spherical with an average diameter of <2 nm. The ultrasmall size clusters were exceedingly immobilized by the PC-SH on the surface, resulting in excellent biocompatibility and antibacterial activity simultaneously. The biocompatible, antimicrobial PC-AgNCs exhibit interesting advantages compared with other silver antimicrobial agents for medical applications. PMID- 27689805 TI - The Organophosphate Paraoxon and Its Antidote Obidoxime Inhibit Thrombin Activity and Affect Coagulation In Vitro. AB - Organophosphates (OPs) are potentially able to affect serine proteases by reacting with their active site. The potential effects of OPs on coagulation factors such as thrombin and on coagulation tests have been only partially characterized and potential interactions with OPs antidotes such as oximes and muscarinic blockers have not been addressed. In the current study, we investigated the in vitro interactions between coagulation, thrombin, the OP paraoxon, and its antidotes obidoxime and atropine. The effects of these substances on thrombin activity were measured in a fluorescent substrate and on coagulation by standard tests. Both paraoxon and obidoxime but not atropine significantly inhibited thrombin activity, and prolonged prothrombin time, thrombin time, and partial thromboplastin time. When paraoxon and obidoxime were combined, a significant synergistic effect was found on both thrombin activity and coagulation tests. In conclusion, paraoxon and obidoxime affect thrombin activity and consequently alter the function of the coagulation system. Similar interactions may be clinically relevant for coagulation pathways in the blood and possibly in the brain.

AB - This study assesses the environmental impacts of four measures proposed for upgrading of the urban wastewater system of Eindhoven and the Dommel River in The Netherlands, against the base case, "do-nothing" option. The measures aim to reduce the overall environmental impact of the Eindhoven urban wastewater system (UWS) by targeting river dissolved oxygen depletion and ammonia peaks, reducing combined sewer overflows, and enhancing nutrient removal. The measures are evaluated using a life cycle analysis with the boundaries including the receiving river section by means of an integrated model of the UWS. An uncertainty analysis of the estimated impacts has been performed to support the outcomes. The study also uses the economic concept of shadow prices to assign relative weights of socio-economic importance to the estimated life cycle impacts. This novel integration of tools complements the assessments of this UWS with the inclusion of long-term global environmental impacts and the investigation of trade-offs between different environmental impacts through a single monetary unit. The results support the selection of deeper clarifiers as the most environmentally beneficial measure for upgrade. PMID- 27689807 TI - Expression of microRNA-129-2-3p and microRNA-935 in plasma and brain tissue of human refractory epilepsy. AB - OBJECTIVE: Numerous microRNAs (miRNAs) are differentially expressed in specific diseases, suggesting possible use as diagnostic or prognostic biomarkers. The purpose of this study is to investigate the expression levels of miR-129-2-3p and miR-935 in cortical brain tissue and plasma samples from controls and refractory temporal lobe epilepsy (TLE) patients to evaluate the utility of these measures as diagnostic biomarkers. METHODS: The study was divided into three phases. First, cortical brain tissue samples from nine refractory TLE patients and eight controls were screened for differential miRNA expression using the Affymetrix miRNA 4.0 microarray. Second, real-time quantitative PCR (qRT-PCR) was used to verify the microarray results in brain tissue samples from 13 refractory TLE patients and 13 healthy controls (including those studied by microarray analysis). Third, we tested the expression levels of selected miRNAs in plasma samples from 25 refractory TLE patients and 25 healthy volunteers by qRT-PCR. The capacity of miR-129-2-3p and miR-935 expression to distinguish refractory TLE from health controls was tested by receiver operator characteristics (ROC) curve analysis. RESULTS: (1) High-resolution miRNA arrays indicated that miR-129-2-3p and miR-935 were significantly upregulated in the cortical brain tissues of TLE patients compared to controls. (2) qRT-PCR confirmed upregulated miR-129-2-3p expression in the brain tissue(P<0.0001) and plasma samples(P=0.0008) of refractory TLE patients. (3) The expression of miR-935 in epilepsy patients was higher than control group, however, there are no significant statistical differences between them whether in plasma samples(P=0.644) or in tissue samples(P=0.258). (4) ROC analysis of miRNA-129-2-3p showed that the area under the curve (AUC) was 0.929 (95% CI: 0.833-1.000; p=0.000) for brain tissue and 0.778 (95% CI: 0.640-0.915; p=0.001) for plasma. CONCLUSION: Expression of miRNA 129-2-3p was upregulated in cortical brain tissue and plasma samples from patients with refractory TLE, but miR-935 not. Plasma miRNA-129-2-3p has great potential as a non-invasive biomarker for early detection and clinical evaluation of refractory TLE. PMID- 27689809 TI - Age related normogram for antral follicle count in general population and comparison with previous studies. AB - OBJECTIVE: To construct antral follicle count (AFC) nomogram of general population for every age and to compare our data with previous studies to assess whether available AFC nomograms present any geographical inconsistency. STUDY DESIGN: A prospective cross-sectional study was conducted to document AFC nomogram among women in 20-50 years with regular menstrual bleeding. Patients admitted with hirsutism, menstrual irregularity, diagnosis of current/history of endometrioma and hormonal drug use within the last 6 months were excluded. For the final analysis, a total of 381 eligible women were recruited in which all scanning was performed in the early follicular phase. The 25th, 50th and 75th percentiles were compared with previous nomogram. RESULTS: The mean decrease of AFC in each year was 0.41. Among the age groups, there were no statistical significance between 20-24, 25-29 and 30-34, whereas decline in AFC was obvious after 35 years and beyond. The figures comparing our data and previous studies depicted similar steady decline at 25th, 50th and 75th percentiles. CONCLUSION: The current age related nomogram presented a steady decline in AFC that became significant after 35 years in otherwise healthy women with regular menstrual bleeding. Those percentiles might be used as a reference guide to point out the current status of ovarian reserve for a given woman. Additionally, producing nomogram might enforce using percentiles instead of constant thresholds to define various medical conditions such as polycystic ovarian morphology or diminished ovarian reserve. However, longitudinal data with larger sample size are still needed for the validation of those percentiles. PMID- 27689810 TI - The immune responses and expression of metallothionein (MT) gene and heat shock protein 70 (HSP 70) in juvenile rockfish, Sebastes schlegelii, exposed to waterborne arsenic (As3+). AB - Juvenile rockfish, Sebastes schlegelii (mean length 16.4+/-1.9cm, and mean weight 71.6+/-6.4g) were exposed for 20days with the different levels of waterborne arsenic concentration (0, 50, 100, 200 and 400MUg/L). The plasma cortisol of S. schlegelii was significantly increased by the waterborne arsenit exposure. In the immune responses, the immunoglobulin M (Ig M) and lysozyme activity of S. schlegelii were significantly increased by the waterborne arsenic exposure. The acetylcholinesterase (AChE) activity of S. schlegelii was inhibited by the waterborne arsenic exposure. The substantial increases in the gene expression such as metallothionein (MT) and heat shock protein 70 (HSP 70) were observed by the waterborne arsenic exposure. The results demonstrated that waterborne arsenic exposure can induce the significant alterations in the immune responses and specific gene expression of S. schlegelii. PMID- 27689811 TI - Role of miR-199b-5p in regulating angiogenesis in mouse myocardial microvascular endothelial cells through HSF1/VEGF pathway. AB - Our study explored effects of miR-199b-5p on angiogenesis in mouse myocardial microvascular endothelial cells (MMVECs) and the involved working mechanisms. We applied explant culture to incubate C57/BL6 mouse MMVECs. Lipofection was used to transfect miR-199b-5p mimic, miR-199b-5p inhibitor and miR-199b-5p scramble respectively. MMVECs were divided into miR-199b-5p up-regulation, miR-199b-5p down-regulation and control groups based on above sequence. Expressions of miR 199b-5p, heat shock factor protein 1 (HSF1) mRNA were assessed by real-time quantitative polymerase chain reaction (RT-QPCR). Expressions of HSF1 and vascular endothelial growth factor (VEGF) were assessed by Western Blotting. Cell proliferation was assessed by CCK8. Tubule formation assay was conducted to assess formation of blood vessels. Results showed that miR-199b-5p up/down regulation groups exhibited no obvious differences in the expressions of HSF1 mRNA compared to control group. However, miR-199b-5p up-regulation group recorded lower expressions of HSF1 and VEGF in the level of protein, and reduced cell proliferation and tubule formation. Whereas, miR-199b-5p down-regulation group presented the contrary results. The experiment indicated that miR-199b-5p can regulate proliferation and angiogenesis in mouse MMVECs through the pathway of HSF1/VEGF.

AB - Inclusion of drugs in cyclodextrins (CDs) is a recognized tool for modifying several properties such as solubility, stability, bioavailability, and so on. The photoreactive behavior of the beta-CD/ketoprofen (KP) complex upon UV exposure showed a significant increase in photodecarboxylation, whereas the secondary degradation products by hydroxylation of the benzophenone moiety were inhibited. The results may account for an improvement of KP photophysical properties upon inclusion, thus better fostering its topical use. To correlate the structural details of the inclusion with these results, an NMR spectroscopic study of KP upon inclusion in beta-CD was performed. Effects of the magnetically anisotropic centers of KP, changing their orientations upon inclusion and giving chemical shift variations, were specifically correlated with the results of the molecular dynamic simulations and ab initio calculations. In the large variety of papers focusing on the structural analysis of beta-CD complexes, this work represents one of the few examples in which a detailed analysis of these simultaneous upfield-downfield NMR shifts of the same aromatic molecule upon inclusion is reported. Interestingly, the results demonstrate that the observed upfield and downfield shifts upon inclusion are not related to any direct magnetic role of beta-CD. The conformational change of KP upon the inclusion process consists of a slight reduction in the angle between the two phenyl rings and in a remarkable reduction in the mobility of the carboxyl group, the latter being one of the main contributions to the NMR resonance shifts. These structural details help in understanding the features of the inclusion complex and, eventually, the driving force for its formation.

AB - Single particle cryo-Electron Microscopy (cryo-EM) is a technique that allows the structural characterization of macromolecules without the need for crystallization. For certain type of samples that are ideally suited for cryo-EM studies it has been possible to reach high-resolution structures following relatively standard procedures. Other biological systems remain highly challenging, even for cryo-EM. Challenges may involve the scarcity of the sample, poor stability of the complexes, and most often, the intrinsic flexibility of biological molecules. Among these challenging samples are large eukaryotic transcription complexes, which suffer from all such shortcomings. Here we report how we have recently tried to overcome those challenges in order to improve our structural understanding of the human transcription pre-initiation complex assembly and the transcription initiation process. Parallel efforts have also been carried out for budding yeast transcription initiation complexes, allowing comparisons that establish both the overall conservation and the specific structural differences between the two systems.

AB - Pd-catalyzed cross-coupling reactions that form C-N bonds have become useful methods to synthesize anilines and aniline derivatives, an important class of compounds throughout chemical research. A key factor in the widespread adoption of these methods has been the continued development of reliable and versatile catalysts that function under operationally simple, user-friendly conditions. This review provides an overview of Pd-catalyzed N-arylation reactions found in both basic and applied chemical research from 2008 to the present. Selected examples of C-N cross-coupling reactions between nine classes of nitrogen-based coupling partners and (pseudo)aryl halides are described for the synthesis of heterocycles, medicinally relevant compounds, natural products, organic materials, and catalysts. PMID- 27689814 TI - Heparan sulfates and the decrease of N-glycans promote early adipogenic differentiation rather than myogenesis of murine myogenic progenitor cells. AB - In vitro, extracted muscle satellite cells, called myogenic progenitor cells, can differentiate either in myotubes or preadipocytes, depending on environmental factors and the medium. Transcriptomic analyses on glycosylation genes during satellite cells differentiation into myotubes showed that 31 genes present a significant variation of expression at the early stages of murine myogenic progenitor cells (MPC) differentiation. In the present study, we analyzed the expression of 383 glycosylation related genes during murine MPC differentiation into preadipocytes and compared the data to those previously obtained during their differentiation into myotubes. Fifty-six glycosylation related genes are specifically modified in their expression during early adipogenesis. The variations correspond mainly to: a decrease of N-glycans, and of alpha (2,3) and (2,6) linked sialic acids, and to a high level of heparan sulfates. A high amount of TGF-beta1 in extracellular media during early adipogenesis was also observed. It seems that the increases of heparan sulfates and TGF-beta1 favor pre adipogenic differentition of MPC and possibly prevent their myogenic differentiation. PMID- 27689815 TI - Motor cortical dysfunction develops in spinocerebellar ataxia type 3. AB - OBJECTIVE: Spinocerebellar ataxia type 3 (SCA3) is an inherited neurodegenerative disorder characterized by cerebellar ataxia and variable expression of clinical features beyond the cerebellum. To gain further insights into disease pathophysiology, the present study explored motor cortex function in SCA3 to determine whether cortical dysfunction was present and if this contributed to the development of clinical manifestations. METHODS: Clinical phenotyping and longitudinal assessments were combined with central (threshold-tracking transcranial magnetic stimulation) and peripheral (nerve excitability) techniques in 11 genetically characterized SCA3 patients. RESULTS: Short-interval intracortical inhibition was significantly reduced in presymptomatic and symptomatic SCA3 patients (-1.3+/-1.4%) compared to healthy controls (10.3+/ 0.7%, P<0.0005), with changes evident prior to clinical onset of ataxia and related to worsening severity (R=-0.78, P<0.005). Central motor conduction time was also significantly prolonged in presymptomatic and symptomatic SCA3 patients (7.5+/-0.4ms) compared to healthy controls (5.3+/-0.2ms, P<0.0005) and related to clinical severity (R=0.81, P<0.005). Markers of peripheral motor neurodegeneration and excitability did not correlate with cortical hyperexcitability or ataxia. CONCLUSIONS: Simultaneous investigation of clinical status, and central and peripheral nerve function has identified progressive cortical dysfunction in SCA3 patients related to the development of ataxia. SIGNIFICANCE: These findings suggest alteration in cortical activity is associated with SCA3 pathogenesis and neurodegeneration. PMID- 27689816 TI - Voltage-Rectified Current and Fluid Flow in Conical Nanopores. AB - Ion current rectification (ICR) refers to the asymmetric potential-dependent rate of the passage of solution ions through a nanopore, giving rise to electrical current-voltage characteristics that mimic those of a solid-state electrical diode. Since the discovery of ICR in quartz nanopipettes two decades ago, synthetic nanopores and nanochannels of various geometries, fabricated in membranes and on wafers, have been extensively investigated to understand fundamental aspects of ion transport in highly confined geometries. It is now generally accepted that ICR requires an asymmetric electrical double layer within the nanopore, producing an accumulation or depletion of charge-carrying ions at opposite voltage polarities. Our research groups have recently explored how the voltage-dependent ion distributions and ICR within nanopores can induce novel nanoscale flow phenomena that have applications in understanding ionics in porous materials used in energy storage devices, chemical sensing, and low-cost electrical pumping of fluids. In this Account, we review our most recent investigations on this topic, based on experiments using conical nanopores (10 300 nm tip opening) fabricated in thin glass, mica, and polymer membranes. Measurable fluid flow in nanopores can be induced either using external pressure forces, electrically via electroosmotic forces, or by a combination of these two forces. We demonstrate that pressure-driven flow can greatly alter the electrical properties of nanopores and, vice versa, that the nonlinear electrical properties of conical nanopores can impart novel and useful flow phenomena. Electroosmotic flow (EOF), which depends on the magnitude of the ion fluxes within the double layer of the nanopore, is strongly coupled to the accumulation/depletion of ions. Thus, the same underlying cause of ICR also leads to EOF rectification, i.e., unequal flows occurring for the same voltage but opposite polarities. EOF rectification can be used to electrically pump fluids with very precise control across membranes containing conical pores via the application of a symmetric sinusoidal voltage. The combination of pressure and asymmetric EOF can also provide a means to generate new nanopore electrical behaviors, including negative differential resistance (NDR), in which the current through a conical pore decreases with increasing driving force (applied voltage), similar to solid-state tunnel diodes. NDR results from a positive feedback mechanism between the ion distributions and EOF, yielding a true bistability in both fluid flow and electrical current at a critical applied voltage. Nanopore-based NDR is extremely sensitive to the surface charge near the nanopore opening, suggesting possible applications in chemical sensing.

The ideal transformation of hydrazones into the corresponding hydrazonamide through selective carbon-hydrogen (C-H) bond functionalization represents one of the most step- and atom-economical methods. This SET umpolung strategy features mild conditions and a remarkably broad substrate scope, offering an entirely new substrate class to direct C-H amination.

AB - A binder-free cobalt phosphate hydrate (Co3(PO4)2.8H2O) multilayer nano/microflake structure is synthesized on nickel foam (NF) via a facile hydrothermal process. Four different concentrations (2.5, 5, 10, and 20 mM) of Co2+ and PO4-3 were used to obtain different mass loading of cobalt phosphate on the nickel foam. The Co3(PO4)2.8H2O modified NF electrode (2.5 mM) shows a maximum specific capacity of 868.3 C g-1 (capacitance of 1578.7 F g-1) at a current density of 5 mA cm-2 and remains as high as 566.3 C g-1 (1029.5 F g-1) at 50 mA cm-2 in 1 M NaOH. A supercapattery assembled using Co3(PO4)2.8H2O/NF as the positive electrode and activated carbon/NF as the negative electrode delivers a gravimetric capacitance of 111.2 F g-1 (volumetric capacitance of 4.44 F cm-3). Furthermore, the device offers a high specific energy of 29.29 Wh kg-1 (energy density of 1.17 mWh cm-3) and a specific power of 4687 W kg-1 (power density of 187.5 mW cm-3). PMID- 27689819 TI - Block Copolymer-Assisted Solvothermal Synthesis of Hollow Bi2MoO6 Spheres Substituted with Samarium. AB - Hollow spherical structures of ternary bismuth molybdenum oxide doped with samarium (Bi2-xSmxMoO6) were successfully synthesized via development of a Pluronic P123 (PEO20-PPO70-PEO20)-assisted solvothermal technique. Density functional theory calculations have been performed to improve our understanding of the effects of Sm doping on the electronic band structure, density of states, and band gap of the material. The calculations for 0 <= x <= 0.3 revealed a considerably flattened conduction band minimum near the Gamma point, suggesting that the material can be considered to possess a quasi-direct band gap. In contrast, for x = 0.5, the conduction band minimum is deflected toward the U point, making it a distinctly indirect band gap material. The effects of a hollow structure as well as Sm substitution on the absorbance and fluorescence properties of the materials produced increased emission intensities at low Sm concentrations (x = 0.1 and 0.3), with x = 0.1 displaying a peak photoluminescence intensity 13.2 times higher than for the undoped bulk sample. Subsequent increases in the Sm concentration resulted in quenching of the emission intensity, indicative of the onset of a quasi-direct-to-indirect electronic band transition. These results indicate that both mesoscale structuring and Sm doping will be promising routes for tuning optoelectronic properties for future applications such as catalysis and photocatalysis. PMID- 27689820 TI - Kinetics of Excited Oxygen Formation in Shock-Heated O2-Ar Mixtures. AB - The formation of electronically excited atomic oxygen was studied behind reflected shock waves using cavity-enhanced absorption spectroscopy. Mixtures of 1% O2-Ar were shock-heated to 5400-7500 K, and two distributed-feedback diode lasers near 777.2 and 844.6 nm were used to measure time-resolved populations of atomic oxygen's 5S degrees and 3S degrees electronic states, respectively. Measurements were compared with simulated population time histories obtained using two different kinetic models that accounted for thermal nonequilibrium effects: (1) a multitemperature model and (2) a reduced collisional-radiative model. The former assumed a Boltzmann distribution of electronic energy, whereas the latter allowed for non-Boltzmann populations by treating the probed electronic states as pseudospecies and accounting for dominant electronic excitation/de-excitation processes. The effects of heavy-particle collisions were investigated and found to play a major role in the kinetics of O atom electronic excitation at the conditions studied. For the first time, rate constants (kM) for O atom electronic excitation from the ground state (3P) due to collisions with argon atoms were directly inferred using the reduced collisional-radiative model, kM(3P -> 5S degrees ) = 7.8 * 10-17T0.5 exp(-1.061 * 105K/T) +/- 25% cm3 s-1 and kM(3P -> 3S degrees ) = 2.5 * 10-17T0.5 exp(-1.105 * 105K/T) +/- 25% cm3 s-1.

AB - The aims of this study were the characterization of the upper olfactory epithelium of cultured and wild Senegalese sole mature males at histological and transcriptomic (using RNA-Seq) level. No significant differences in tissue structure, cell types and cellular distribution pattern (olfactory sensory neurons) were identified between cultured and wild specimens. Deep transcriptomic analysis showed 2387 transcripts were differentially expressed between cultured and wild groups. A detailed analysis identified the differentially expressed transcripts included some olfactory receptors (OR, TAAR and V2R-like) and transcripts related with the control of reproduction such as the brain aromatase cytochrome P450 and tachykinin-3. Also a wide set of genes related with lipid sensing, metabolism and transport were differentially expressed and these transcripts were often down-regulated in cultured fish. Furthermore, cultured males presented a higher expression of genes related with goblet cells and mucin production that modulates innate and adaptive immune responses. All these changes in gene expression could be explained by different nutritional status and diet preference. The different expression of transcripts related to olfaction, reproduction, nutrient sensing and immune system demonstrate distinct differences in functionalities between cultured and wild soles providing new clues about the sexual dysfunction in this species. PMID- 27689821 TI - High-Valent Manganese-Oxo Valence Tautomers and the Influence of Lewis/Bronsted Acids on C-H Bond Cleavage. AB - The addition of Lewis or Bronsted acids (LA = Zn(OTf)2, B(C6F5)3, HBArF, TFA) to the high-valent manganese-oxo complex MnV(O)(TBP8Cz) results in the stabilization of a valence tautomer MnIV(O-LA)(TBP8Cz*+). The ZnII and B(C6F5)3 complexes were characterized by manganese K-edge X-ray absorption spectroscopy (XAS). The position of the edge energies and the intensities of the pre-edge (1s to 3d) peaks confirm that the Mn ion is in the +4 oxidation state. Fitting of the extended X-ray absorption fine structure (EXAFS) region reveals 4 N/O ligands at Mn-Nave = 1.89 A and a fifth N/O ligand at 1.61 A, corresponding to the terminal oxo ligand. This Mn-O bond length is elongated compared to the MnV(O) starting material (Mn-O = 1.55 A). The reactivity of MnIV(O-LA)(TBP8Cz*+) toward C-H substrates was examined, and it was found that H* abstraction from C-H bonds occurs in a 1:1 stoichiometry, giving a MnIV complex and the dehydrogenated organic product. The rates of C-H cleavage are accelerated for the MnIV(O LA)(TBP8Cz*+) valence tautomer as compared to the MnV(O) valence tautomer when LA = ZnII, B(C6F5)3, and HBArF, whereas for LA = TFA, the C-H cleavage rate is slightly slower than when compared to MnV(O). A large, nonclassical kinetic isotope effect of kH/kD = 25-27 was observed for LA = B(C6F5)3 and HBArF, indicating that H-atom transfer (HAT) is the rate-limiting step in the C-H cleavage reaction and implicating a potential tunneling mechanism for HAT. The reactivity of MnIV(O-LA)(TBP8Cz*+) toward C-H bonds depends on the strength of the Lewis acid. The HAT reactivity is compared with the analogous corrole complex MnIV(O-H)(tpfc*+) recently reported (J. Am. Chem. Soc. 2015, 137, 14481-14487). PMID- 27689824 TI - Effects of Intermolecular Charge Transfer in Liquid Water on Raman Spectra. AB - The low-frequency vibrational spectrum of liquid water is composed of contributions from the intermolecular librational and translation modes. The existence of these two modes introduces difficulty into the simulation of experimentally obtained Raman spectra. We constructed a polarizability function for a water model that includes intramolecular charge flow (CF) effects, intermolecular charge transfer (CT) effects, and intermolecular dipole-induced dipole (DID) effects. We computed the one-dimensional (1D) Raman and terahertz (THz) spectra with all of these effects included (CFCT-DID) and compared with experimental spectra. We find that the CFCT-DID function provides a better description of the experimental results, because the CT effects reduce the polarizability only for translational motion to which parallelly polarized (VV) and perpendicularly polarized (VH) Raman spectra are sensitive. In our calculations of two-dimensional (2D) Raman and THz-Raman spectra, we observe the enhancement of echo signals in both cases. The details of the CFCT-DID function, along with its source code, are provided in the Supporting Information. PMID- 27689826 TI - Natpara for the treatment of hypoparathyroidism. AB - INTRODUCTION: Hypoparathyroidism is a rare endocrine disorder characterized by hypocalcaemia and hyperphosphatemia, due to absent or inappropriately low parathyroid hormone levels. For management of chronic hypoparathyroidism, current treatment options involve oral calcium and vitamin D. This standard treatment cannot resolve all problematic aspects of the disease, such as abnormal bone remodeling and reduced quality of life, and is associated with long-term complications, including nephrolithiasis, nephrocalcinosis, renal impairment, cataracts and cerebral calcifications. AREAS COVERED: In 2015, the FDA (Food and Drug Administration) approved rhPTH (1-84), named Natpara(r), a bioengineered recombinant human PTH, for the management of hypoparathyroidism of any etiology, except Autosomal Dominant Hypocalcemia, not well controlled with calcium and active vitamin D. Herein, the authors review its chemistry, pharmacodynamics, pharmacokinetics and clinical efficacy for hypoparathyroidism. EXPERT OPINION: Replacement therapy with rhPTH (1-84) is a fundamental step in the treatment of chronic hypoparathyroidism in cases not well controlled by standard therapy, providing the natural hormone that is lacking for the maintenance of normal calcium levels, and reducing long-term risks associated with conventional therapy. Nevertheless, given the chronic nature of the disease, in the future, further studies will have to be performed to evaluate long-term efficacy and safety of the drug. PMID- 27689825 TI - Inhibin A and inhibin B producing ovarian fibrothecoma revealed by suppression of follicle stimulating hormone (FSH) in a post-menopausal woman: report of the first case. AB - In this report, we describe the first case ever reported in the literature, of an inhibin-A (INHA) and inhibin-B (INHB) producing fibrothecoma. A post-menopausal woman was referred to our unit because of follicle stimulating hormone (FSH) level below the reference interval for postmenopausal women. By contrast luteinizing hormone, hCG, and estradiol levels were within normal range. This discrepancy suggested the secretion of FSH inhibitory factors. INHB and INHA levels were markedly elevated for age, 475 pg/mL and 100 pg/mL, respectively. Ultrasonography and MRI showed a pelvic mass of indeterminate nature. Abnormal inhibin secretion is generally observed in granulosa cell tumors. In this case this etiology was unlikely because of low estradiol and AMH levels. Surgical exploration revealed a 10 cm mass of the left ovary proven histologically to be an ovarian fibrothecoma (OFT). After tumor removal, INHB and INHA levels decreased rapidly. Only three cases of OFT with an important secretion of INHB have been reported to date. INHA secretion has never been associated with OFT. There is a need to develop coupled hormone and imaging strategies to diagnose the source of INH secretion in case of FSH/LH discrepancy.

AB - Hydrogels based upon terpolymers of methacrylic acid, N-vinyl pyrrolidone, and poly(ethylene glycol) are developed and characterized for their ability to respond to changes in environmental pH and to partition protein therapeutics of varying molecular weights and isoelectric points. P((MAA-co-NVP)-g-EG) hydrogels are synthesized with PEG-based cross-linking agents of varying length and incorporation densities. The composition is confirmed using FT-IR spectroscopy and shows peak shifts indicating hydrogen bonding. Scanning electron microscopy reveals microparticles with an irregular, planar morphology. The pH-responsive behavior of the hydrogels is confirmed under equilibrium and dynamic conditions, with the hydrogel collapsed at acidic pH and swollen at neutral pH. The ability of the hydrogels to partition model protein therapeutics at varying pH and ionic strength is evaluated using three model proteins: insulin, porcine growth hormone, and ovalbumin. Finally, the microparticles are evaluated for adverse interactions with two model intestinal cell lines and show minimal cytotoxicity at concentrations below 5 mg mL-1 . PMID- 27689828 TI - Metabolic Fate of Branched-Chain Amino Acids During Adipogenesis, in Adipocytes From Obese Mice and C2C12 Myotubes. AB - Branched-chain amino acid (BCAA) catabolism is regulated by the branched-chain aminotransferase (BCAT2) and the branched-chain alpha-keto acid dehydrogenase complex (BCKDH). BCAT2 and BCKDH expression and activity are modified during adipogenesis and altered in adipose tissues of mice with genetic or diet-induced obesity. However, little is known about how these modifications and alterations affect the intracellular metabolic fate of BCAAs during adipogenesis, in adipocytes from mice fed a control or high-fat diet or in C2C12 myotubes. Here, we demonstrate that BCAAs are mainly incorporated into proteins during the early stages of adipocyte differentiation. However, they are oxidized and incorporated into lipids during the late days of differentiation. Conversely, 92% and 97% of BCAA were oxidized, 1.6% and 6% were used for protein synthesis and 1.2% and 1.5% were incorporated into lipids in adipocytes from epididymal and subcutaneous adipose tissue, respectively. All three pathways were decreased in adipocytes from mice fed a high-fat diet. In C2C12 myotubes, leucine is mainly used for protein synthesis and palmitate is incorporated into lipids. Interestingly, leucine decreased both palmitate oxidation and its incorporation to lipids and proteins; and palmitate increased leucine oxidation and decreased its incorporation to lipids and proteins in a dose-dependent manner. These results demonstrate that BCAA metabolic fate differs between the early and late stages of adipocyte differentiation and in adipocytes from mice fed a control or high-fat diet; and that leucine affects the metabolic fate of palmitate and vice versa in C2C12 myotubes.

PMID- 27689831 TI - Noninvasive Physiologic Vascular Studies: A Guide to Diagnosing Peripheral Arterial Disease. AB - Noninvasive physiologic vascular studies play an important role in the diagnosis and characterization in peripheral arterial disease (PAD) of the lower extremity. These studies evaluate the physiologic parameters of blood flow through segmental arterial pressures, Doppler waveforms, and pulse volume recordings. Collectively, they comprise a powerful toolset for defining the functionality of the arterial system, localizing the site of disease, and providing prognostic data. This technology has been widely adopted by diverse medical specialty practitioners, including radiologists, surgeons, cardiologists, and primary care providers. The use of these studies increased substantially between 2000 and 2010. Although they do not employ imaging, they remain a critical component for a comprehensive radiologic vascular laboratory. A strong presence of radiology in the diagnosis of PAD adds value in that radiologists have shifted to noninvasive alternatives to diagnostic catheter angiography (DCA), such as computed tomography (CT) and magnetic resonance (MR) angiography, which provide a more efficient, less expensive, and lower-risk alternative. Other specialties have increased the use of DCA during the same period. The authors provide a review of the relevant anatomy and physiology of PAD as well as the associated clinical implications. In addition, guidelines for interpreting the ankle-brachial index, segmental pressures, Doppler waveforms, and pulse volume recordings are reviewed as well as potential limitations of these studies. Noninvasive physiologic vascular studies are provided here for review with associated correlating angiographic, CT, and/or MR findings covering the segmental distribution of PAD as well as select nonatherosclerotic diagnoses.

PMID- 27689830 TI - RGD targeting of human ferritin iron oxide nanoparticles enhances in vivo MRI of vascular inflammation and angiogenesis in experimental carotid disease and abdominal aortic aneurysm. AB - PURPOSE: To evaluate Arg-Gly-Asp (RGD)-conjugated human ferritin (HFn) iron oxide nanoparticles for in vivo magnetic resonance imaging (MRI) of vascular inflammation and angiogenesis in experimental carotid disease and abdominal aortic aneurysm (AAA). MATERIALS AND METHODS: HFn was genetically engineered to express the RGD peptide and Fe3 O4 nanoparticles were chemically synthesized inside the engineered HFn (RGD-HFn). Macrophage-rich left carotid lesions were induced by ligation in FVB mice made hyperlipidemic and diabetic (n = 14), with the contralateral right carotid serving as control. Murine AAAs were created by continuous angiotensin II infusion in ApoE-deficient mice (n = 12), while control mice underwent saline infusion (n = 8). All mice were imaged before and after intravenous injection with either RGD-HFn-Fe3 O4 or HFn-Fe3 O4 using a gradient echo sequence on a whole-body 3T clinical scanner, followed by histological analysis. The nanoparticle accumulation was assessed by the extent of T2*-induced carotid lumen reduction (% lumen loss) or aortic T2*-weighted signal intensity reduction (% SI [signal intensity] loss). RESULTS: RGD-HFn-Fe3 O4 was taken up more than HFn-Fe3 O4 in both the ligated left carotid arteries (% lumen loss; 69 +/- 9% vs. 36 +/- 7%, P = 0.01) and AAAs (% SI loss; 47 +/- 6% vs. 20 +/- 5%, P = 0.01). The AAA % SI loss correlated positively with AAA size (r = 0.89, P < 0.001). Histology confirmed the greater accumulation and colocalization of RGD HFn-Fe3 O4 to both vascular macrophages and endothelial cells. CONCLUSION: RGD HFn-Fe3 O4 enhances in vivo MRI by targeting both vascular inflammation and angiogenesis, and provides a promising translatable MRI approach to detect high risk atherosclerotic and aneurysmal vascular diseases.

PMID- 27689836 TI - Blue-Light Transmittance of Esthetic Monolithic CAD/CAM Materials With Respect to Their Composition, Thickness, and Curing Conditions. AB - Determining the amount of blue light (360-540nm) passing through nine monolithic computer-aided design/computer-aided manufacturing (CAD/CAM) materials depends on material thickness, initial irradiance, and the distance between the curing unit and the specimen's surface. A total of 180 specimens of two thicknesses (1 mm and 2 mm, n=10/subgroup) were fabricated from TelioCAD, VITA CAD-Temp (VCT), experimental nanocomposite, LAVA Ultimate (LU), VITA ENAMIC (VE), VITA MarkII (VM), IPS EmpressCAD (IEC), IPS e.maxCAD (IEM), and CELTRA DUO (CD). The irradiance passing through the CAD/CAM materials and thicknesses was measured using a light-emitting-diode curing unit with standard-power, high-power, and plasma modes by means of a USB4000 spectrometer. The curing unit was placed directly on the specimen's surface at 2- and 4-mm distances from the specimen's surface. Data were analyzed using a multivariate analysis and one-way analysis of variance with the post hoc Scheffe test (p<0.05). The highest transmitted irradiance was measured for VM and LU, followed by VCT and IEC, while the lowest values showed VE, followed by IEM and CD. The highest transmitted irradiance was recorded by exposing the material to the plasma mode, followed by the high- and standard-power modes. The measured irradiance was decreased by increasing the specimen's thickness from 1 to 2 mm. Fewer differences were measured when the curing unit was placed at 0 or 2 mm from the specimen's surface, and the irradiance passing through the specimens was lower at a distance of 4 mm.

AB - OBJECTIVE: For some esthetic clinical situations, it is necessary to finish crown margins on direct restorative materials to preserve tissue integrity, bonding integrity, and biological width. The purpose of this research was to investigate microleakage at the interface between bonded lithium disilicate crowns and various direct restorative materials in a class III and class V position. METHODS AND MATERIALS: Class III or class V restorations were prepared on one side of extracted incisors with either Tetric EvoCeram, Tetric Evoceram Bulk, Fuji II LC, or Tetric Evoflow. The teeth were prepared for and received a lithium disilicate crown. After load fatiguing, the specimens were thermo-cycled with a fuchsin dye and sectioned. The depth and area of dye penetration were measured with a dimensional grid in micrometers using stereomicroscopy and reported as mean dye depth and area (MUm) +/- SD. The comparison of multiple categorical independent variables with ratio scale dependent variables was evaluated with an analysis of variance and Tukey's post hoc analysis. RESULTS: A statistically significant higher dye penetration was noted for all treatment groups compared with the positive control (side opposite the restoration after sagittal sectioning was used as positive control) regardless of material or placement area (p<0.05). In comparing treatment groups, the Tetric EvoFlow experienced a statistically higher dye penetration than did the other treatment groups regardless of material or placement area (p<0.05). There was no statistically significant difference between the Tetric EvoCeram, Tetric Evoceram Bulk, and Fuji II LC materials regardless of placement area (p>0.05). CONCLUSIONS: Within the limitations of this study, it can be concluded that flowable composite materials as finish lines that interact with resin cements could lead to exacerbated interfacial degradation. Finishing lithium disilicate all-ceramic crowns on flowable resin composite materials in the esthetic zone should be used with caution. If necessary, finishing lithium disilicate all-ceramic crowns on nanofilled resin composite or resin-modified glass ionomer materials seems to provide the least dye penetration depth and area. PMID- 27689833 TI - Elastography in Chronic Liver Disease: Modalities, Techniques, Limitations, and Future Directions. AB - Chronic liver disease has multiple causes, many of which are increasing in prevalence. The final common pathway of chronic liver disease is tissue destruction and attempted regeneration, a pathway that triggers fibrosis and eventual cirrhosis. Assessment of fibrosis is important not only for diagnosis but also for management, prognostic evaluation, and follow-up of patients with chronic liver disease. Although liver biopsy has traditionally been considered the reference standard for assessment of liver fibrosis, noninvasive techniques are the emerging focus in this field. Ultrasound-based elastography and magnetic resonance (MR) elastography are gaining popularity as the modalities of choice for quantifying hepatic fibrosis. These techniques have been proven superior to conventional cross-sectional imaging for evaluation of fibrosis, especially in the precirrhotic stages. Moreover, elastography has added utility in the follow up of previously diagnosed fibrosis, the assessment of treatment response, evaluation for the presence of portal hypertension (spleen elastography), and evaluation of patients with unexplained portal hypertension. In this article, a brief overview is provided of chronic liver disease and the tools used for its diagnosis. Ultrasound-based elastography and MR elastography are explored in depth, including a brief glimpse into the evolution of elastography. Elastography is based on the principle of measuring tissue response to a known mechanical stimulus. Specific elastographic techniques used to exploit this principle include MR elastography and ultrasonography-based static or quasistatic strain imaging, one-dimensional transient elastography, point shear-wave elastography, and supersonic shear-wave elastography. The advantages, limitations, and pitfalls of each modality are emphasized. (c)RSNA, 2016. PMID- 27689839 TI - Epub Clinical Relevance Statements. PMID- 27689840 TI - Water Sorption and Solubility of Luting Agents Used Under Ceramic Laminates With Different Degrees of Translucency. AB - PURPOSE: The aim of this study was to evaluate the effect of low-thickness ceramic laminate translucency on water sorption and solubility in resin luting agents. METHODS AND MATERIALS: Ceramic slides (15*0.7 mm) were generated using lithium disilicate (IPS e.max Press, Ivoclar-Vivadent, Schaan, Liechtenstein) that were A1 in color and had decreasing degrees of translucency (high, medium, and low). A slide of transparent glass of similar size was used as the control. Under each slide, 15 specimens (8*0.5 mm) of differing composite materials from the same manufacturer (3M ESPE Dental Products, St Paul, MN, USA) were prepared (n=5): light-cured resin cement (RelyX Veneer); dual-cured resin cement (RelyX ARC); and flowable composite (Z350XT Flow). To evaluate the loss or gain of mass, the specimens were dried until a constant mass was reached. Then, they were immersed in water for seven days and weighed immediately following removal from water. Subsequently, the specimens were dried again until a constant mass was obtained. The mass measurements were used to calculate the water sorption and solubility. Statistical analyses were carried out using a two-way analysis of variance and the Tukey test. RESULTS: Under the high-translucency ceramic slides, all of the luting agents showed similar performance regarding water sorption; the flowable composite resin and the light-cured resin cement had the lowest solubility values. Under the medium- and low-translucency surfaces, the dual cured resin cement and the flowable composite resin showed better performance with respect to water sorption and solubility. CONCLUSIONS: In the case of high translucency laminates, luting agents with different activation methods might be used. However, even in thin sections, decreasing the translucency of the laminate led to significant loss of light penetration, indicating a decreased likelihood of the physical activation of the resin cement. PMID- 27689841 TI - Fractographical Analysis and Biomechanical Considerations of a Tooth Restored With Intracanal Fiber Post: Report of the Fracture and Importance of the Fiber Arrangements. AB - OBJECTIVE: This article aims to present a fractographic analysis of an anterior tooth restored with a glass fiber post with parallel fiber arrangement, taking into account force vectors, finite element analysis, and scanning electron microscopy (SEM). METHODS: A patient presented at the Faculty of Dentistry (Federal University of Santa Maria, Brazil) with an endodontically treated tooth (ETT), a lateral incisor that had a restorable fracture. The treatment was performed, and the fractured piece was analyzed using stereomicroscopy, SEM, and finite element analysis. RESULTS: The absence of remaining coronal tooth structure might have been the main factor for the clinical failure. We observed different stresses actuating in an ETT restored with a fiber post as well as their relationship with the ultimate fracture. Tensile, compression, and shear stresses presented at different levels inside the restored tooth. Tensile and compressive stresses acted together and were at a maximum in the outer portions and a minimum in the inner portions. In contrast, shear stresses acted concomitantly with tensile and compressive stresses. Shear was higher in the inner portions (center of the post), and lower in the outer portions. This was confirmed by finite element analysis. The SEM analysis showed tensile and compression areas in the fiber post (exposed fibers=tensile areas=lingual surface; nonexposed fibers=compression areas=buccal surface) and shear areas inside the post (scallops and hackle lines). Stereomicroscopic analysis showed brown stains in the crown/root interface, indicating the presence of microleakage (tensile area=lingual surface). CONCLUSION: We concluded that glass fiber posts with parallel fibers (0 degrees ), when restoring anterior teeth, present a greater fracture potential by shear stress because parallel fibers are not mechanically resistant to support oblique occlusal loads. Factors such as the presence of remaining coronal tooth structure and occlusal stability assist in the biomechanical equilibrium of stresses that act upon anterior teeth. PMID- 27689842 TI - Aging and well-being in Goa, India: a qualitative study. AB - OBJECTIVES: The population of India is aging rapidly. This demographic shift brings with it a host of challenges to the health and well-being of older adults, including the increased prevalence of non-communicable diseases, among them depressive disorders. In this paper, we report on qualitative research intended to inform the development of a locally acceptable and appropriate intervention to improve the well-being of older adults in Goa, India and, specifically, to prevent late-life depression. METHOD: Semi-structured interviews with 20 individuals, aged 60 years and older, attending two primary care clinics in Goa, India. Transcripts were reviewed to identify emerging themes, a coding scheme was developed and thematic analyses were conducted. RESULTS: Analyses of the interview transcripts revealed the following key themes: (1) notions of old age tended to be negative and there were widespread fears of becoming widowed or incapacitated; (2) the most frequently reported health conditions were joint pain, diabetes and heart disease; (3) emotional distress was described using the terms 'tension', 'stress', 'worry' and 'thinking'; (4) family issues often involved financial matters, difficult relationships with daughters-in-law and conflicted feelings about living with the family or independently; (5) other than a pension scheme, participants did not know of community resources available to older adults. CONCLUSIONS: Our findings are in general agreement with those of previous research, and with our experiences of working with older adults in Pittsburgh and the Netherlands. This research will inform the development of an intervention to prevent depression in older adults in Goa. PMID- 27689843 TI - Trading direct for indirect defense? Phytochrome B inactivation in tomato attenuates direct anti-herbivore defenses whilst enhancing volatile-mediated attraction of predators. AB - Under conditions of competition for light, which lead to the inactivation of the photoreceptor phytochrome B (phyB), the growth of shade-intolerant plants is promoted and the accumulation of direct anti-herbivore defenses is down regulated. Little is known about the effects of phyB on emissions of volatile organic compounds (VOCs), which play a major role as informational cues in indirect defense. We investigated the effects of phyB on direct and indirect defenses in tomato (Solanum lycopersicum) using two complementary approaches to inactivate phyB: illumination with a low red to far-red ratio, simulating competition, and mutation of the two PHYB genes present in the tomato genome. Inactivation of phyB resulted in low levels of constitutive defenses and down regulation of direct defenses induced by methyl jasmonate (MeJA). Interestingly, phyB inactivation also had large effects on the blends of VOCs induced by MeJA. Moreover, in two-choice bioassays using MeJA-induced plants, the predatory mirid bug Macrolophus pygmaeus preferred VOCs from plants in which phyB was inactivated over VOCs from control plants. These results suggest that, in addition to repressing direct defense, phyB inactivation has consequences for VOC-mediated tritrophic interactions in canopies, presumably attracting predators to less defended plants, where they are likely to find more abundant prey. PMID- 27689844 TI - Micro-CT assessment of dentinal micro-cracks after root canal filling procedures. AB - AIM: To evaluate the frequency of dentinal micro-cracks after root canal filling procedures with GuttaCore (GC), cold lateral compaction (CLC) and warm vertical compaction (WVC) techniques in mandibular molars using micro-computed tomographic analysis. METHODOLOGY: Thirty mesial roots of mandibular molars, with a type II Vertucci's canal configuration, were prepared to working length with a Reciproc R40 instrument and randomly assigned to one of the three experimental groups (n = 10), according to the technique used for root filling: GC, CLC or WVC. The GC group was filled with a size 40 GC obturator, whilst CLC and WVC groups used conventional gutta-percha cones. AH Plus sealer was used in all groups. The specimens were scanned at an isotropic resolution of 14.25 MUm before and after root canal preparation and after root filling. Then, all pre- and postoperative cross-sectional images of the roots (n = 41 660) were screened to identify the presence of dentinal defects. RESULTS: Overall, 30.75% (n = 12 810) of the pre- + post-filling images displayed dentinal defects. In the GC, CLC and WVC groups, dentinal micro-cracks were observed in 18.68% (n = 2510), 15.99% (n = 2389) and 11.34% (n = 1506) of the cross-sectional images, respectively. All micro-cracks identified in the post-filling scans were also observed in the corresponding post preparation images. CONCLUSION: Root fillings in all techniques did not induce the development of new dentinal micro-cracks. PMID- 27689845 TI - Outcome of neoadjuvant therapies for cancer of the oesophagus or gastro oesophageal junction based on a national data registry. AB - BACKGROUND: Randomized trials have shown that neoadjuvant treatment improves survival in the curative treatment of oesophageal and gastro-oesophageal junction cancer. Results from population-based observational studies are, however, sparse and ambiguous. METHODS: This prospective population-based cohort study included all patients who had oesophagectomy for cancer in Sweden, excluding clinical T1 N0, recorded in the National Register for Oesophageal and Gastric Cancer, 2006 2014. Patients were stratified into three groups: surgery alone, neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy. RESULTS: Neoadjuvant treatment was given to 521 patients (51.1 per cent) and 499 (48.9 per cent) received surgery alone. Neoadjuvant chemotherapy increased the risk of postoperative surgical complications compared with surgery alone (adjusted odds ratio 2.01, 95 per cent c.i. 1.24 to 3.25; P = 0.005). Postoperative mortality was significantly increased after neoadjuvant chemoradiotherapy compared with surgery alone (odds ratio 2.37, 1.06 to 5.29; P = 0.035). Survival improved in patients with squamous cell carcinoma after neoadjuvant chemotherapy, whereas after neoadjuvant chemoradiotherapy survival was significantly improved only in the subgroup with the highest performance status and without known co-morbidity. In adenocarcinoma there was a trend towards improved overall survival after neoadjuvant chemotherapy, but neoadjuvant chemoradiotherapy did not offer a survival benefit. Stratified analysis including only patients with adenocarcinoma in the highest performance category without known co-morbidity showed a strong trend towards improved survival after neoadjuvant chemotherapy compared with surgery alone (adjusted hazard ratio 0.47, 0.21 to 1.04; P = 0.061). CONCLUSION: For patients with squamous cell carcinoma of the oesophagus or gastro-oesophageal junction, neoadjuvant treatments seemed to increase long-term survival, but also the risk of postoperative morbidity and mortality, compared with surgery alone. Neither neoadjuvant treatment option seemed to improve survival significantly among patients with adenocarcinoma, compared with surgery alone. PMID- 27689846 TI - Enzymatic Ugi Reaction with Amines and Cyclic Imines. AB - The application of the Ugi reaction to the construction of new peptide scaffolds is an important goal of organic chemistry. To date, there are no examples of the Ugi reaction being performed with a cyclic imine and amine simultaneously. The application of 2-substituted cyclic imines in an enzymatic three-component Ugi type reaction provides an elegant and attractive synthesis of substituted pyrrolidine and piperidine derivatives in up to 60 % yield. Results on studies of the selection of an enzyme, amount of water, and solvent used in a novel three component Ugi reaction and the limitations thereof are reported herein. The presented methodology exploiting enzyme promiscuity in the multicomponent reaction fulfills the requirements associated with green chemistry. Several methods, such as isotope labeling and enzyme inhibition, were used to probe the possible mechanism of this complex synthesis. This research is the first example of an enzyme-catalyzed Ugi-type reaction with an imine, amine, and isocyanide.

AB - RATIONALE: Structural analogs of the bioactive lipid 1-palmitoyl-2-oleoyl-sn glycero-3-phosphoglycerol were synthesized with a xylitol polar head group and both diacyl and diether radyl groups. Mass spectral characterization of xylitol phospholipids (PX) was carried out using collisional activation and high resolution mass measurements of positive molecular ion species and compared with the phosphatidylglycerol (PG) analogs. METHODS: PX were synthesized using a transphosphatidylation reaction catalyzed by phospholipase D and purified by high performance liquid chromatography (HPLC). Compounds were subjected to electrospray ionization and collision-induced dissociation (CID) was performed using a tandem quadrupole mass spectrometer to generate positive and negative molecular ions. Diether phospholipids were additionally analyzed by high resolution mass spectrometry as protonated and sodiated molecular species in positive ion mode. RESULTS: Ester-linked PX analogs behaved similarly to PG after collisional activation of [M - H]- . The product ions formed by CID of the diether PG and PX negative ions only revealed information about the head group with no information about the aliphatic chains. In contrast, CID of protonated and sodiated diether phospholipid positive ions revealed reactions corresponding to cleavage of the ether chain, likely occurring by charge-driven reaction mechanisms. CONCLUSIONS: Novel PX analogs with diacyl and diether radyl substituents of the glycerol backbone were characterized by tandem mass spectrometry. These unique diether phospholipid analogs enabled exploration of ether cleavage reactions of the positive molecular ion species resulting from collision-induced decomposition.

AB - The conjugate of paclitaxel (PTX) and docosahexaenoic acid has entered into clinical trials. However, the most recent clinical outcomes fell short of expectations, due to the extremely slow drug release from the hydrophobic conjugates. Herein, a novel prodrug-based nanoplatform self-assembled by the disulfide bond linked conjugates of PTX and oleic acid for rapid and differential release of PTX in tumor cells is reported. This redox-responsive prodrug nanosystem demonstrates multiple therapeutic advantages, including one-step facile fabrication, high drug-loading efficiency (56%, w/w), on-demand drug release responding to redox stimuli, as well as favorable cellular uptake and biodistribution. These advantages result in significantly enhanced antitumor efficacy in vivo, with the tumor almost completely disappearing in mice. Such a uniquely engineered prodrug-nanosystem has great potential to be used as potent chemotherapeutic nanomedicine in clinical cancer therapy. PMID- 27689850 TI - Silica-Supported Silver Nitrate as a Highly Active Dearomatizing Spirocyclization Catalyst: Synergistic Alkyne Activation by Silver Nanoparticles and Silica. AB - Silica-supported AgNO3 (AgNO3 -SiO2 ) catalyzes the dearomatizing spirocyclization of alkyne-tethered aromatics far more effectively than the analogous unsupported reagent; in many cases, reactions which fail using unsupported AgNO3 proceed effectively with AgNO3 -SiO2 . Mechanistic studies indicate that this is a consequence of silver nanoparticle formation on the silica surface combined with a synergistic effect caused by the silica support itself. The remarkable ease with which the reagent can be prepared and used is likely to be of much synthetic importance, in particular, by making nanoparticle catalysis more accessible to non-specialists. PMID- 27689849 TI - Improved human endometrial stem cells differentiation into functional hepatocyte like cells on a glycosaminoglycan/collagen-grafted polyethersulfone nanofibrous scaffold. AB - Liver tissue engineering (TE) is rapidly emerging as an effective technique which combines engineering and biological processes to compensate for the shortage of damaged or destroyed liver tissues. We examined the viability, differentiation, and integration of hepatocyte-like cells on an electrospun polyethersulfone (PES) scaffold, derived from human endometrial stem cells (hEnSCs). Natural polymers were separately grafted on plasma-treated PES nanofibers, that is, collagen, heparan sulfate (HS) and collagen-HS. Galactosilated PES (PES-Gal) nanofibrous were created. The engineering and cell growth parameters were considered and compared with each sample. The cellular studies revealed increased cell survival, attachment, and normal morphology on the bioactive natural polymer-grafted scaffolds after 30 days of hepatic differentiation. The chemical and molecular assays displayed hepatocyte differentiation. These cells were also functional, showing glycogen storage, alpha-fetoprotein, and albumin secretion. The HS nanoparticle-grafted PES nanofibers demonstrated a high rate of cell proliferation, differentiation, and integration. Based on the observations mentioned above, engineered tissue is a good option in the future, for the commercial production of three-dimensional liver tissues for clinical purposes.

Annulus fibrosus (AF) monolayers were poorly responsive to the HA-oligos, proMMP-2 levels were marginally elevated and levels were MMP-9 unaffected. ProMMP-2 displayed a strong dose-dependent increase in the nucleus pulposus (NP) monolayers. In AF alginate bead cultures, proMMP-2 and active MMP-9 increased up to day 10, in NP cultures proMMP-2 was progressively converted to active MMP-2 over days 7-10 and active MMP-9 levels were elevated on day 10. A steady decline in MMP-2 and MMP-9 activity was evident over days 2-10 in the non-stimulated NP cultures. Disc cell viabilities were >=92 +/- 5% in all cultures indicating that the HA-oligo was not cytotoxic. Reverse-transcription polymerase chain reaction demonstrated an upregulation in MMP1, MMP113 and ADAMTS1 and the anabolic matrix repair genes ACAN, COL1A1 and COL2A1 in the NP by HA-oligos, whereas AF MMP13, ADAMTS1, ADAMTS4 and ADAMTS5, ACAN and COL2A1 were down-regulated; this differential regulation is expected to promote clearance of granulation/scar tissue from AF defects and matrix replenishment. The AF defect sites contained enlarged annular lamellae in vivo in response to the HA oligos, which is consistent with an active repair response. Masson trichrome and PicroSirius red histology and immunolocalization of type I collagen supported active remodelling in the outer lesion zone by the HA-oligo treatment but not the inner lesion.

AB - Although alternative forms of statistical and verbal information are routinely used to convey species' extinction risk to policymakers and the public, little is known about their effects on audience information processing and risk perceptions. To address this gap in literature, we report on an experiment that was designed to explore how perceptions of extinction risk differ as a function of five different assessment benchmarks (Criteria A-E) used by scientists to classify species within IUCN Red List risk levels (e.g., Critically Endangered, Vulnerable), as well as the role of key individual differences in these effects (e.g., rational and experiential thinking styles, environmental concern). Despite their normative equivalence within the IUCN classification system, results revealed divergent effects of specific assessment criteria: on average, describing extinction risk in terms of proportional population decline over time (Criterion A) and number of remaining individuals (Criterion D) evoked the highest level of perceived risk, whereas the single-event probability of a species becoming extinct (Criterion E) engendered the least perceived risk. Furthermore, participants scoring high in rationality (analytic thinking) were less prone to exhibit these biases compared to those low in rationality. Our findings suggest that despite their equivalence in the eyes of scientific experts, IUCN criteria are indeed capable of engendering different levels of risk perception among lay audiences, effects that carry direct and important implications for those tasked with communicating about conservation status to diverse publics.

AB - AIM: Type 2 diabetes mellitus and metabolic syndrome are two diseases related to disorders of lipid and carbohydrate metabolism and insulin resistance. Peroxisome proliferator-activated receptors (PPARs) are a class of nuclear receptors that control the metabolism of lipids/carbohydrates and are considered targets for both diseases. PPAR affinity and selectivity are critical points to design drug candidates with appropriated pharmacodynamic/kinetic profiles. MATERIALS & METHODS: Hologram quantitative structure-activity relationships studies were conducted, as well molecular docking and molecular interaction field calculations, in order to explain affinity and selectivity of selected compounds. RESULTS: The constructed hologram quantitative structure-activity relationship models are robust and predictive (values of q2 and r2test above 0.70). CONCLUSION: The quantitative structure-activity relationship models and docking/GRID analyses indicated that carboxyl group of indole-sulfonamide derivatives could interact at helix-3 region, being considered important point of PPAR-delta selectivity.

AB - In this study, a flow cytometry (FC) protocol was implemented to measure poly(3 hydroxybutyrate) (PHB) content in a halophilic bacterium, to have a faster and easier control of the process. The halophilic bacterium Halomonas boliviensis was stained with BODIPY 493/503 and analyzed using FC. Bacterial polymer accumulation induced by two different nutrient limitations during the operation of a 2 L bioreactor was studied using traditional gas chromatography (GC) analysis and FC. The application of this rapid and straightforward method is useful to obtain complex and precise information about PHB accumulation that could be used for the monitoring, control and optimization of the production of PHB. A clear correlation between the PHB concentration determined by GC and the fluorescence signal obtained from stained bacteria by using FC was observed. Additionally, the heterogeneity of bacterial population as a function of PHB content was measured. (c) 2016 American Institute of Chemical Engineers Biotechnol. Prog., 33:276-284, 2017.

AB - Dentofacial developmental abnormalities have been reported in head and neck rhabdomyosarcoma (HNRMS) patients treated with conventional radiotherapy technique and chemotherapy. This current study investigates dentofacial long-term effects among HNRMS survivors managed with intensity-modulated radiotherapy (IMRT) and chemotherapy. In general, IMRT is a more effective 3D-conformal radiotherapy technique, which delivers high doses of radiation to the tumor target while minimizing doses received by the surrounding normal tissues. The medical records and radiographs of thirteen patients were reviewed to identify the following: 1. Facial asymmetry and jaw hypoplasia. 2. Effects on the dental tissue causing tooth agenesis/hypodontia, root agenesis/stunting/malformation, and/or enamel hypoplasia. 3. Trismus, hyposalivation/xerostomia. Seven patients presented with facial asymmetry and jaw hypoplasia, 9 patients presented with effects on the dental tissue [root agenesis/stunting/malformation (9), tooth agenesis/hypodontia (7) and enamel hypoplasia (3)] and 7 patients developed trismus and /or xerostomia. All patients with facial asymmetry and jaw hypoplasia also developed dental abnormalities. Patients with dentofacial developmental abnormalities were <=7 years of age at treatment. Our study shows that dentofacial developmental abnormalities are still a burden in the era of IMRT and as prognosis of childhood malignancy improves and more patients survive, these late dentofacial sequelae among childhood cancer survivors will become more common. Dental oncologists should be integral members in the management of children with head and neck cancers. PMID- 27689859 TI - Effect of uric acid-lowering therapy on blood pressure: systematic review and meta-analysis. AB - BACKGROUND: The purpose of this meta-analysis was to determine if uric acid lowering therapy is associated with a decrease in blood pressure (BP) and serum creatinine levels. MATERIALS AND METHODS: Medline, Cochrane, EMBASE, and Google Scholar databases were searched until 29 June 2016, with keywords: uric-acid lowering therapy, allopurinol, febuxostat, uricosuric, and BP. Only randomized controlled trials were included. The primary outcomes were reduction in systolic BP (SBP) and diastolic BP (DBP), and secondary was reduction in serum creatinine level. RESULTS: Patients treated with allopurinol had greater reduction in SBP (standardized difference in means [SDM] = 0.321, 95% confidence interval [CI]: 0.145-0.497, p < 0.001), DBP (SDM = 0.260, 95% CI: 0.102 to 0.417, p = 0.001), and creatinine level (SDM = 0.312, 95% CI: 0.008 to 0.615, p = 0.044) than control patients. Subgroup analysis showed that allopurinol significantly decreased SBP whether or not antihypertensive drugs were being administered; a decrease in DBP was only seen in patients receiving antihypertensive drugs. Low dose allopurinol (<=300 mg/day) was more effective at reducing SBP than high-dose (>300 mg/day) in patients receiving antihypertensive drugs. CONCLUSIONS: These results support that allopurinol decreases BP and creatinine levels in patients with hyperuricemia. KEY MESSAGES Allopurinol decreases SBP and DPB, and creatinine levels in patients with hyperuricemia. Allopurinol resulted in a significant decrease in SBP in patients with or without treatment of antihypertensive drugs. A dose of allopurinol of <=300 mg per day might be more effective than a higher dose. PMID- 27689860 TI - Hearing voices, dissociation, and the self: A functional-analytic perspective. AB - In the current article, we review existing models of the etiology of voice hearing. We summarize the argument and evidence that voice hearing is primarily a dissociative process involving critical aspects of self. We propose a complementary perspective on these phenomena that is based on a modern behavioral account of complex behavior known as relational frame theory. This type of approach to voice hearing concerns itself with the functions served for the individual by this voice hearing; the necessary history, such as trauma, that establishes these functions; and the relevant dissociative processes involving self and others. In short, we propose a trauma-dissociation developmental trajectory in which trauma impacts negatively on the development of self through the process of dissociation. Using the relational frame theory concept of relations of perspective taking, our dissociation model purports that trauma gives rise to more coordination than distinction relations between self and others, thus weakening an individual's sense of a distinct self. Voice hearing experiences, therefore, reflect an individual's perceptions of self and others and may indicate impairments in the natural psychological boundaries between these critical related concepts. One clinical implication suggested by this model is that therapeutic intervention should understand the behaviors associated with a sense of self that is fragile and threatened by others. Relations with self and others should be a key focus of therapy as well as interventions designed to enhance a coherent distinct sense of self. PMID- 27689861 TI - Pillbox use, satisfaction, and effectiveness among persons with chronic health conditions. AB - The purpose of this study was to understand how persons with chronic health conditions use pillboxes, their satisfaction with current devices, and the impact of pillbox use on medication adherence. We used convergent parallel mixed methods approach to explore the experiences of 13 regular, 3 occasional, and 5 non pillbox users. Medication consumers completed the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0), an interview about their medication routines, and a medication adherence diary to describe their experiences with their pillboxes. Results demonstrated most participants use pillboxes to help manage their medications, and pillbox users tended to have better medication adherence than nonusers. Participants used a variety of pillboxes differing in size, shape, and color. Users reported selecting pillboxes based on their needs in addition to the demands of their habits and medication regimens. Users were generally satisfied with their pillboxes with an average QUEST score of 4.33. However, participants also identified areas for an improved design of pillboxes. Pillboxes can be an effective strategy to improve medication adherence. Improvements in device prescription, training, research, and design are needed to understand the mechanisms and size of effects of this intervention. PMID- 27689863 TI - Use of a Modified Canadian Occupational Performance Measure for Assistive Technology Outcomes in Postsecondary Education. AB - The Canadian Occupational Performance Measure (COPM) has been used to assess the effectiveness of assistive technology (AT). We explored whether a modified COPM was sensitive to change in perceived performance and satisfaction, and whether frequency of AT use resulted in greater change in the domains measured (reading, writing, note-taking, test-taking, and study skills). Significant interactions were found between time and use frequency with greater change in perceived performance in the daily-use group in several domains. In addition, the intra class correlation showed moderate to strong equivalent forms reliability between two assessment formats. Based on these preliminary results, the ATRC-mCOPM was found to be a sensitive measure of perceived performance and satisfaction utilizing AT services in a postsecondary education setting. PMID- 27689864 TI - Thrombolysis based on magnetically-controlled surface-functionalized Fe3O4 nanoparticle. AB - In this study, the control of magnetic fields to manipulate surface functionalized Fe3O4 nanoparticles by urokinase coating is investigated for thrombolysis in a microfluidic channel. The urokinase-coated Fe3O4 nanoparticles are characterized using particle size distribution, zeta potential measurement and spectroscopic data. Thrombolytic ratio tests reveal that the efficiency for thrombus cleaning is significantly improved when using magnetically-controlled urokinase-coated Fe3O4 nanoparticles than pure urokinase solution. The average increase in the rate of thrombolysis with the use of urokinase-coated Fe3O4 nanoparticles is about 50%. In vitro thrombolysis test in a microfluidic channel using the coated nanoparticles shows nearly complete removal of thrombus, a result that can be attributed to the clot busting effect of the urokinase as it inhibits the possible formation of blood bolus during the magnetically-activated microablation process. The experiment further demonstrates that a thrombus mass of 10.32 mg in the microchannel is fully removed in about 180 s.

AB - OBJECTIVE: To examine the role of cadherin-11, an integral membrane adhesion molecule, in periodontal ligament cells (PDLCs) under mechanical stimulation. MATERIALS AND METHODS: Human PDLCs were cultured and subjected to mechanical stress. Cadherin-11 expression and cell morphology of PDLCs were investigated via immunofluorescence staining. The mRNA and protein expressions of cadherin-11 and type I collagen (Col-I) of PDLCs were evaluated by quantitative real-time polymerase chain reaction and Western blot, respectively. Small interfering RNA was used to knock down cadherin-11 expression in PDLCs. The collagen matrix of PDLCs was examined using toluidine blue staining. RESULTS: Cadherin-11 was expressed in PDLCs. Mechanical stress suppressed cadherin-11 expression in PDLCs with prolonged force treatment time and increased force intensity, accompanied by suppressed beta-catenin expression. Simultaneously, mechanical stress altered cell morphology and repressed Col-I expression in a time- and dose-dependent manner in PDLCs. Moreover, knockdown of cadherin-11 with suppressed beta-catenin expression resulted in altered PDLC morphology and repressed collagen expression, which were consistent with the changes observed under mechanical stress. CONCLUSIONS: Results of this study suggest that cadherin-11 is expressed in PDLCs and modulates PDLC morphology and collagen synthesis in response to mechanical stress, which may play an important role in the homeostasis and remodeling of the PDL under mechanical stimulation. PMID- 27689867 TI - Use of Carbon Nanotubes as a Solid Support To Establish Quantitative (Centrifugation) and Qualitative (Filtration) Immunoassays To Detect Gentamicin Contamination in Commercial Milk. AB - Current methods to detect gentamicin (GEN), a broad-spectrum antibiotic that causes ototoxicity and nephrotoxicity when present in excess, have several limitations. Hence, we have developed two methods using multi-walled carbon nanotubes (MWCNTs) as a solid support to detect GEN. Hybridoma cells (2D12) producing high-sensitivity antibodies against GEN were established. The goat anti mouse antibody was immobilized on MWCNTs directly or using bifunctional polyethylene glycol as a linker. On the basis of the physical characteristics of MWCNTs, a quantitative method involving centrifugation separation and a qualitative method involving filtration separation were established. Various experimental parameters were optimized for GEN detection, and recovery tests were performed. For the quantitative method, the limit of detection (LOD) was 0.048 ng/mL, whereas for the qualitative method, a LOD of 0.1 ng/mL was observed by the naked eye. The proposed immunoassays were applied to commercial milk samples. Thus, these methods show potential application for the detection of GEN. PMID- 27689868 TI - Oral health educational interventions for nursing home staff and residents. AB - BACKGROUND: Associations between nursing home residents' oral health status and quality of life, respiratory tract infections, and nutritional status have been reported. Educational interventions for nurses or residents, or both, focusing on knowledge and skills related to oral health management may have the potential to improve residents' oral health. OBJECTIVES: To assess the effects of oral health educational interventions for nursing home staff or residents, or both, to maintain or improve the oral health of nursing home residents. SEARCH METHODS: We searched the Cochrane Oral Health Trials Register (to 18 January 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2015, Issue 12), MEDLINE Ovid (1946 to 18 January 2016), Embase Ovid (1980 to 18 January 2016), CINAHL EBSCO (1937 to 18 January 2016), and Web of Science Conference Proceedings (1990 to 18 January 2016). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials to 18 January 2016. In addition, we searched reference lists of identified articles and contacted experts in the field. We placed no restrictions on language or date of publication when searching the electronic databases. SELECTION CRITERIA: Randomised controlled trials (RCTs) and cluster RCTs comparing oral health educational programmes for nursing staff or residents, or both with usual care or any other oral healthcare intervention. DATA COLLECTION AND ANALYSIS: Two review authors independently screened articles retrieved from the searches for relevance, extracted data from included studies, assessed risk of bias for each included study, and evaluated the overall quality of the evidence. We retrieved data about the development and evaluation processes of complex interventions on the basis of the Criteria for Reporting the Development and Evaluation of Complex Interventions in healthcare: revised guideline (CReDECI 2). We contacted authors of relevant studies for additional information. MAIN RESULTS: We included nine RCTs involving 3253 nursing home residents in this review; seven of these trials used cluster randomisation. The mean resident age ranged from 78 to 86 years across studies, and most participants were women (more than 66% in all studies). The proportion of residents with dental protheses ranged from 62% to 87%, and the proportion of edentulous residents ranged from 32% to 90% across studies.Eight studies compared educational interventions with information and practical components versus (optimised) usual care, while the ninth study compared educational interventions with information only versus usual care. All interventions included educational sessions on oral health for nursing staff (five trials) or for both staff and residents (four trials), and used more than one active component. Follow-up of included studies ranged from three months to five years.No study showed overall low risk of bias. Four studies had a high risk of bias, and the other five studies were at unclear risk of bias.None of the trials assessed our predefined primary outcomes 'oral health' and 'oral health-related quality of life'. All trials assessed our third primary outcome, 'dental or denture plaque'. Meta analyses showed no evidence of a difference between interventions and usual care for dental plaque (mean difference -0.04, 95% confidence interval (CI) -0.26 to 0.17; six trials; 437 participants; low quality evidence) or denture plaque (standardised mean difference -0.60, 95% CI -1.25 to 0.05; five trials; 816 participants; low quality evidence). None of the studies assessed adverse events of the intervention. AUTHORS' CONCLUSIONS: We found insufficient evidence to draw robust conclusions about the effects of oral health educational interventions for nursing home staff and residents. We did not find evidence of meaningful effects of educational interventions on any measure of residents' oral health; however, the quality of the available evidence is low. More adequately powered and high quality studies using relevant outcome measures are needed. PMID- 27689866 TI - Chemical Proteomic Profiling of Human Methyltransferases. AB - Methylation is a fundamental mechanism used in Nature to modify the structure and function of biomolecules, including proteins, DNA, RNA, and metabolites. Methyl groups are predominantly installed into biomolecules by a large and diverse class of S-adenosyl methionine (SAM)-dependent methyltransferases (MTs), of which there are ~200 known or putative members in the human proteome. Deregulated MT activity contributes to numerous diseases, including cancer, and several MT inhibitors are in clinical development. Nonetheless, a large fraction of the human MT family remains poorly characterized, underscoring the need for new technologies to characterize MTs and their inhibitors in native biological systems. Here, we describe a suite of S-adenosyl homocysteine (SAH) photoreactive probes and their application in chemical proteomic experiments to profile and enrich a large number of MTs (>50) from human cancer cell lysates with remarkable specificity over other classes of proteins. We further demonstrate that the SAH probes can enrich MT-associated proteins and be used to screen for and assess the selectivity of MT inhibitors, leading to the discovery of a covalent inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme implicated in cancer and metabolic disorders. The chemical proteomics probes and methods for their utilization reported herein should prove of value for the functional characterization of MTs, MT complexes, and MT inhibitors in mammalian biology and disease. PMID- 27689869 TI - Rapid, Surfactant-Free, and Quantitative Functionalization of Gold Nanoparticles with Thiolated DNA under Physiological pH and Its Application in Molecular Beacon Based Biosensor. AB - The controlled attachment of thiolated DNA to gold nanoparticles (AuNPs) dictates many applications. This is typically achieved by either "aging-salting" processes or low-pH method, where either Na+ or H+ is used to minimize charge repulsion and facilitate attachment of thiolated DNA onto AuNPs. However, the "aging-salting" process takes a long time, and is prone to aggregation when used with larger AuNPs. Surfactants are needed to precoat and thereby enhance the stability of AuNPs. The low-pH method can disrupt the structural integrity of DNAs. We report here an oligoethylene glycol (OEG) spacer-assisted method that enables quantitative and instantaneous attachment at physiological pH without the need for surfactants. The method is based on our finding that an uncharged OEG spacer as short as six EG units can effectively shield against repulsion between AuNPs and DNAs, substantially enhancing both the adsorption kinetics and thermodynamics of thiolated DNAs. We applied this to thiolated DNAs of various lengths and thiol modification positions and to large AuNPs. Importantly, our method also allows for the direct immobilization of thiolated molecular beacons (MB), and avoids particle aggregation due to intermolecular hydrogen bonding. The prepared MB AuNPs were successfully used for the fluorescent detection of target DNA at nanomolar concentrations. The OEG spacer appears to offer a highly effective parameter for tuning DNA adsorption kinetics and thermodynamics besides pH and salt, providing a novel means for highly controllable and versatile functionalization of AuNPs. PMID- 27689870 TI - Novel Bivalent 99mTc-Complex with N-Methyl-Substituted Hydroxamamide as Probe for Imaging of Cerebral Amyloid Angiopathy. AB - Cerebral amyloid angiopathy (CAA) is characterized by the deposition of amyloid aggregates in the walls of the cerebral vasculature. Recently, the development of molecular imaging probes targeting CAA has been attracting much attention. We previously reported the 99mTc-hydroxamamide (99mTc-Ham) complex with a bivalent benzothiazole scaffold as a binding moiety for amyloid aggregates ([99mTc]BT2) and its utility for CAA-specific imaging. However, the simultaneous generation of two radiolabeled complexes derived from the geometric isomers was observed in the 99mTc-labeling reaction. It was recently reported that the complexation reaction of 99Tc with N-methyl-substituted Ham provided a single 99Tc-Ham complex consisting of two N-methylated Ham ligands with marked stability. In this article, we designed and synthesized a novel N-methylated bivalent 99mTc-Ham complex ([99mTc]MBT2) and evaluated its utility for CAA-specific imaging. N Methyl substitution of [99mTc]BT2 prevented the generation of its isomer in the 99mTc-labeling reaction. Enhanced in vitro stability of [99mTc]MBT2 as compared with [99mTc]BT2 was observed. [99mTc]MBT2 showed very low brain uptake, which is favorable for CAA-specific imaging. An in vitro inhibition assay using beta amyloid aggregates and in vitro autoradiographic examination of brain sections from a Tg2576 mouse and a CAA patient showed a decline in the binding affinity for amyloid aggregates due to N-methylation of the 99mTc-Ham complex. These results suggest that the scaffold of the 99mTc-Ham complex may play important roles in the in vitro stability and the binding affinity for amyloid aggregates. PMID- 27689871 TI - Functional disparities among BCL-2 members in tonsillar and leukemic B-cell subsets assessed by BH3-mimetic profiling. AB - For successful treatment of malignant B-cells it is crucial to understand intrinsic survival requirements in relation to their normal progenitors. Long lived humoral immunity as well as most B-cell malignancies, originate in the germinal center (GC). Murine GC B-cells depend on pro-survival protein MCL-1, but not BCL-XL. In contrast, naive and memory B-cells depend on BCL-2, but not BCL-XL or MCL-1. For human B-cell subsets, the functional relationships among BCL-2 members are unclear, and also if and how they shift after malignant transformation. We here dissect these aspects in human tonsil and primary leukemia (CLL) cells by single and combined treatment with novel, highly specific BH3-mimetics. We found that MCL-1 expression in GC B-cells is regulated post translationally and its importance is highlighted by preferential binding to pro apoptotic BIM. In contrast, BCL-XL is transcriptionally induced and binds solely to weak sensitizer BIK, potentially explaining why BCL-XL is not required for GC B-cell survival. Using novel BH3-mimetics, we found that naive and memory B-cells depend on BCL-2, GC cells predominantly on MCL-1, whereas plasma cells need both BCL-XL and MCL-1 for survival. CLL cells switch from highly sensitive for BCL-2 inhibition to resistant after CD40-stimulation. However, combined inhibition of BCL-2, plus BCL-XL or MCL-1 effectively kills these cells, thus exposing a weakness that may be therapeutically useful. These general principles offer important clues for designing treatment strategies for B-cell malignancies. PMID- 27689873 TI - Autophagy requires poly(adp-ribosyl)ation-dependent AMPK nuclear export. AB - AMPK is a central energy sensor linking extracellular milieu fluctuations with the autophagic machinery. In the current study we uncover that Poly(ADP ribosyl)ation (PARylation), a post-translational modification (PTM) of proteins, accounts for the spatial and temporal regulation of autophagy by modulating AMPK subcellular localisation and activation. More particularly, we show that the minority AMPK pool needs to be exported to the cytosol in a PARylation-dependent manner for optimal induction of autophagy, including ULK1 phosphorylation and mTORC1 inactivation. PARP-1 forms a molecular complex with AMPK in the nucleus in non-starved cells. In response to nutrient deprivation, PARP-1 catalysed PARylation, induced the dissociation of the PARP-1/AMPK complex and the export of free PARylated nuclear AMPK to the cytoplasm to activate autophagy. PARP inhibition, its silencing or the expression of PARylation-deficient AMPK mutants prevented not only the AMPK nuclear-cytosolic export but also affected the activation of the cytosolic AMPK pool and autophagosome formation. These results demonstrate that PARylation of AMPK is a key early signal to efficiently convey extracellular nutrient perturbations with downstream events needed for the cell to optimize autophagic commitment before autophagosome formation. PMID- 27689872 TI - Alternative splicing and cell survival: from tissue homeostasis to disease. AB - Most human genes encode multiple mRNA variants and protein products through alternative splicing of exons and introns during pre-mRNA processing. In this way, alternative splicing amplifies enormously the coding potential of the human genome and represents a powerful evolutionary resource. Nonetheless, the plasticity of its regulation is prone to errors and defective splicing underlies a large number of inherited and sporadic diseases, including cancer. One key cellular process affected by alternative splicing is the programmed cell death or apoptosis. Many apoptotic genes encode for splice variants having opposite roles in cell survival. This regulation modulates cell and tissue homeostasis and is implicated in both developmental and pathological processes. Furthermore, recent evidence has also unveiled splicing-mediated regulation of genes involved in autophagy, another essential process for tissue homeostasis. In this review, we highlight some of the best-known examples of alternative splicing events involved in cell survival. Emphasis is given to the role of this regulation in human cancer and in the response to chemotherapy, providing examples of how alternative splicing of apoptotic genes can be exploited therapeutically. PMID- 27689874 TI - Hepatocyte growth factor renders BRAF mutant human melanoma cell lines resistant to PLX4032 by downregulating the pro-apoptotic BH3-only proteins PUMA and BIM. AB - A large proportion of melanomas harbour the activating BRAFV600E mutation that renders these cells dependent on MAPK signalling for their survival. Although the highly specific and clinically approved BRAFV600E kinase inhibitor, PLX4032, induces apoptosis of melanoma cells bearing this mutation, the underlying molecular mechanisms are not fully understood. Here, we reveal that PLX4032 induced apoptosis depends on the induction of the pro-apoptotic BH3-only protein PUMA with a minor contribution of its relative BIM. Apoptosis could be significantly augmented when PLX4032 was combined with an inhibitor of the pro survival protein BCL-XL, whereas neutralization of the pro-survival family member BCL-2 caused no additional cell death. Although the initial response to PLX4032 in melanoma patients is very potent, resistance to the drug eventually develops and relapse occurs. Several factors can cause melanoma cells to develop resistance to PLX4032; one of them is the activation of the receptor tyrosine kinase cMET on melanoma cells by its ligand, hepatocyte growth factor (HGF), provided by the tumour microenvironment or the cancer cells themselves. We found that HGF mediates resistance of cMET-expressing BRAF mutant melanoma cells to PLX4032-induced apoptosis through downregulation of PUMA and BIM rather than by increasing the expression of pro-survival BCL-2-like proteins. These results suggest that resistance to PLX4032 may be overcome by specifically increasing the levels of PUMA and BIM in melanoma cells through alternative signalling cascades or by blocking pro-survival BCL-2 family members with suitable BH3 mimetic compounds.

PMID- 27689876 TI - LH prevents cisplatin-induced apoptosis in oocytes and preserves female fertility in mouse. AB - Premature ovarian failure and female infertility are frequent side effects of anticancer therapies, owing to the extreme sensitivity of the ovarian reserve oocytes to the damaging effects of irradiation and chemotherapy on DNA. We report here a robust protective effect of luteinizing hormone (LH) on the primordial follicle pool of prepubertal ovaries against the cisplatin (Cs)-induced apoptosis. In vitro LH treatment of prepubertal ovarian fragments generated anti apoptotic signals by a subset of ovarian somatic cells expressing LH receptor (LHR) through cAMP/PKA and Akt pathways. Such signals, reducing the oocyte level of pro-apoptotic TAp63 protein and favoring the repair of the Cs-damaged DNA in the oocytes, prevented their apoptosis. Noteworthy, in vivo administration to prepubertal female mice of a single dose of LH together with Cs inhibited the depletion of the primordial follicle reserve caused by the drug and preserved their fertility in reproductive age, preventing significant alteration in the number of pregnancy and of delivered pups. In conclusion, these findings establish a novel ovoprotective role for LH and further support the very attracting prospective to use physiological 'fertoprotective' approaches for preventing premature infertility and risks linked to precocious menopause in young patients who survived cancer after chemotherapy. PMID- 27689879 TI - Mass Spectrometric and Functional Aspects of Drug-Protein Conjugation. AB - The covalent binding of drugs (metabolites) to proteins to form drug-protein adducts can have an adverse effect on the body. These adducts are thought to be responsible for idiosyncratic drug reactions including severe drug hypersensitivity reactions. Major advances in proteomics technology have allowed for the identification and quantification of target proteins for certain drugs. Human serum albumin (HSA) and Hb have been identified as accessible targets and potential biomarkers for drug-protein adducts formation, for numerous drugs (metabolites) including beta-lactam antibiotics, reactive drug metabolites such as quinone imines (acetaminophen) and acyl glucuronides (diclofenac), and covalent inhibitors (neratinib). For example, MS/MS analysis of plasma samples from patients taking flucloxacillin revealed that flucloxacillin and its 5 hydroxymethyl metabolite formed covalent adducts with lysine residues on albumin via opening of the beta-lactam ring. Other proteins such as P450 and keratin are also potential targets for covalent binding. However, for most drugs, the properties of these target proteins including their location, their quantity, the timing of conjugate generation, and their biological function are not well understood. In this review, currently available proteomic technologies including MS/MS analysis to identify antigens, precise location of modifications, and the immunological consequence of hapten-protein complex are illustrated. Moving forward, identification of the nature of the antigenic determinants that trigger immune responses to drug-protein adducts will increase our ability to predict idiosyncratic toxicity for a given compound.

AB - The Parkinson's disease (PD)-related protein F-box only protein 7 (Fbxo7) is the substrate-recognition component of the Skp1-Cullin-F-box protein E3 ubiquitin ligase complex. We have recently shown that PD-associated mutations in Fbxo7 disrupt mitochondrial autophagy (mitophagy), suggesting a role for Fbxo7 in modulating mitochondrial homeostasis. Here we report that Fbxo7 deficiency is associated with reduced cellular NAD+ levels, which results in increased mitochondrial NADH redox index and impaired activity of complex I in the electron transport chain. Under these conditions of compromised respiration, mitochondrial membrane potential and ATP contents are reduced, and cytosolic reactive oxygen species (ROS) production is increased. ROS activates poly (ADP-ribose) polymerase (PARP) activity in Fbxo7-deficient cells. PARP inhibitor restores cellular NAD+ content and redox index and ATP pool, suggesting that PARP overactivation is cause of decreased complex I-driven respiration. These findings bring new insight into the mechanism of Fbxo7 deficiency, emphasising the importance of mitochondrial dysfunction in PD.

AB - Vitex pubescens is a Malaysian therapeutic plant employed in traditional drug to remedy a variety of disorders. The purpose of this research is to assess the gastroprotective efficiency of V. pubescens leaves against ethanol-induced gastric hemorrhagic laceration in rats. Animals were randomly allocated into seven groups and pre-treated, separately, with 10% Tween 20 (normal and ulcer control groups), 20 mg/kg omeprazole (reference group), and 62.5, 125, 250, and 500 mg/kg of V. pubescens extract (experimental groups). All animals were sacrificed after another hour. Histological evaluation of the ulcer control group revealed significant injury to the gastric mucosa with edema and leucocyte infiltration of the submucosal layer. PAS staining, showed remarkably intense magenta color, remarkable increase of HSP70 and decrease of Bax proteins in rats pre-treated with plant extracts compared to the ulcer control group. Gastric homogenates revealed a remarkable increase in endogenous antioxidant enzyme activities (CAT, SOD, GSH) and a decrease in the lipid peroxidation level (MDA) in animals pre-treated with V. pubescens extract compared with the ulcer control group. The gastroprotective activity of this plant might be related to increased antioxidant enzymes and decrease lipid peroxidation upsurge of HSP70 and reduced expression of Bax proteins. PMID- 27689881 TI - The Insulin-Like Proteins dILPs-2/5 Determine Diapause Inducibility in Drosophila. AB - Diapause is an actively induced dormancy that has evolved in Metazoa to resist environmental stresses. In temperate regions, many diapausing insects overwinter at low temperatures by blocking embryonic, larval or adult development. Despite its Afro-tropical origin, Drosophila melanogaster migrated to temperate regions of Asia and Europe where females overwinter as adults by arresting gonadal development (reproductive diapause) at temperatures <13 degrees C. Recent work in D. melanogaster has implicated the developmental hormones dILPs-2 and/or dILP3, and dILP5, homologues of vertebrate insulin/insulin-like growth factors (IGFs), in reproductive arrest. However, polymorphisms in timeless (tim) and couch potato (cpo) dramatically affect diapause inducibility and these dILP experiments could not exclude this common genetic variation contributing to the diapause phenotype. Here, we apply an extensive genetic dissection of the insulin signaling pathway which allows us to see both enhancements and reductions in egg development that are independent of tim and cpo variations. We show that a number of manipulations dramatically enhance diapause to ~100%. These include ablating, or reducing the excitability of the insulin-producing cells (IPCs) that express dILPs-2,3,5 employing the dilp2,3,5-/- triple mutant, desensitizing insulin signaling using a chico mutation, or inhibiting dILP2 and 5 in the hemolymph by over-expressing Imaginal Morphogenesis Protein-Late 2 (Imp-L2). In addition, triple mutant dilp2,3,5-/- females maintain high levels of diapause even when temperatures are raised in adulthood to 19 degrees C. However at 22 degrees C, these females all show egg development revealing that the effects are conditional on temperature and not a general female sterility. In contrast, over-expression of dilps-2/5 or enhancing IPC excitability, led to levels of ovarian arrest that approached zero, underscoring dILPs-2 and 5 as key antagonists of diapause. PMID- 27689883 TI - Efficacy of Six-Week Extended-Dose Nevirapine Varies by Infant Birth Weight with Greatest Relative Efficacy in Low Birth Weight Infants. AB - Latest World Health Organization guidelines recommend weight-based nevirapine prophylaxis for all HIV-exposed infants in resource-limited settings, yet low birth weight (LBW) infants (< 2500 g) have been understudied. Using data from the NIH-funded India six-week extended-dose nevirapine (SWEN) study, a randomized clinical trial of SWEN versus single-dose nevirapine (SD) for prevention of breast-milk HIV-1 transmission, we examined the relative impact of SWEN among 737 mother-infant pairs stratified by infant birth weight. Birth weight groups were defined as very LBW (VLBW) <= 2000 g, moderate LBW (MLBW) >2000 g and <= 2500 g, and normal birth weight (NBW) > 2500 g. Outcomes were HIV-1 infection, HIV-1 infection or death by 12 months, and severe adverse events (SAEs). The Kaplan Meier method was used to estimate probability of efficacy outcomes in birth weight groups, and differential effects of SWEN by birth weight group were examined using Cox proportional hazards models adjusting for independent risk factors for HIV maternal-to-child transmission and significant covariates. Among 50 VLBW, 249 MLBW, and 433 NBW infants, 50% were randomized to SWEN; median gestational age was 36, 38 and 38 weeks, respectively; and there was no difference in breastfeeding duration (p = 0.99). Compared to SD: SWEN-treated VLBW had lower estimates of HIV-1 infection (13% vs. 38%, p = 0.004) and HIV-1 infection or death (13% vs. 41%, p = 0.002); SWEN-treated MLBW had lower estimated HIV-1 infection (13% vs. 17%, p = 0.042); and efficacy endpoints were similar by treatment arm in NBW. In multivariate analysis, SWEN was associated with reduced risk of HIV-1 infection or death by 83% (p = 0.03) in VLBW versus 45% (p = 0.05) in MLBW. SAE frequency was similar by treatment arm in VLBW (68% vs. 76%, p = 0.53) and MLBW (37% vs. 36%, p = 0.93). SWEN may safely increase HIV free survival among HIV-exposed LBW infants with greatest protective advantage among infants <= 2000 g.

PMID- 27689884 TI - Knockdown of the schizophrenia susceptibility gene TCF4 alters gene expression and proliferation of progenitor cells from the developing human neocortex. AB - BACKGROUND: Common variants in the TCF4 gene are among the most robustly supported genetic risk factors for schizophrenia. Rare TCF4 deletions and loss-of function point mutations cause Pitt-Hopkins syndrome, a developmental disorder associated with severe intellectual disability. METHODS: To explore molecular and cellular mechanisms by which TCF4 perturbation could interfere with human cortical development, we experimentally reduced the endogenous expression of TCF4 in a neural progenitor cell line derived from the developing human cerebral cortex using RNA interference. Effects on genome-wide gene expression were assessed by microarray, followed by Gene Ontology and pathway analysis of differentially expressed genes. We tested for genetic association between the set of differentially expressed genes and schizophrenia using genome-wide association study data from the Psychiatric Genomics Consortium and competitive gene set analysis (MAGMA). Effects on cell proliferation were assessed using high content imaging. RESULTS: Genes that were differentially expressed following TCF4 knockdown were highly enriched for involvement in the cell cycle. There was a nonsignificant trend for genetic association between the differentially expressed gene set and schizophrenia. Consistent with the gene expression data, TCF4 knockdown was associated with reduced proliferation of cortical progenitor cells in vitro. LIMITATIONS: A detailed mechanistic explanation of how TCF4 knockdown alters human neural progenitor cell proliferation is not provided by this study. CONCLUSION: Our data indicate effects of TCF4 perturbation on human cortical progenitor cell proliferation, a process that could contribute to cognitive deficits in individuals with Pitt-Hopkins syndrome and risk for schizophrenia. PMID- 27689885 TI - Prion Aggregates Are Recruited to the Insoluble Protein Deposit (IPOD) via Myosin 2-Based Vesicular Transport. AB - Aggregation of amyloidogenic proteins is associated with several neurodegenerative diseases. Sequestration of misfolded and aggregated proteins into specialized deposition sites may reduce their potentially detrimental properties. Yeast exhibits a distinct deposition site for amyloid aggregates termed "Insoluble PrOtein Deposit (IPOD)", but nothing is known about the mechanism of substrate recruitment to this site. The IPOD is located directly adjacent to the Phagophore Assembly Site (PAS) where the cell initiates autophagy and the Cytoplasm-to-Vacuole Targeting (CVT) pathway destined for delivery of precursor peptidases to the vacuole. Recruitment of CVT substrates to the PAS was proposed to occur via vesicular transport on Atg9 vesicles and requires an intact actin cytoskeleton and "SNAP (Soluble NSF Attachment Protein) Receptor Proteins (SNARE)" protein function. It is, however, unknown how this vesicular transport machinery is linked to the actin cytoskeleton. We demonstrate that recruitment of model amyloid PrD-GFP and the CVT substrate precursor-aminopeptidase 1 (preApe1) to the IPOD or PAS, respectively, is disturbed after genetic impairment of Myo2 based actin cable transport and SNARE protein function. Rather than accumulating at the respective deposition sites, both substrates reversibly accumulated often together in the same punctate structures. Components of the CVT vesicular transport machinery including Atg8 and Atg9 as well as Myo2 partially co localized with the joint accumulations. Thus we propose a model where vesicles, loaded with preApe1 or PrD-GFP, are recruited to tropomyosin coated actin cables via the Myo2 motor protein for delivery to the PAS and IPOD, respectively. We discuss that deposition at the IPOD is not an integrated mandatory part of the degradation pathway for amyloid aggregates, but more likely stores excess aggregates until downstream degradation pathways have the capacity to turn them over after liberation by the Hsp104 disaggregation machinery. PMID- 27689886 TI - Variation in perfluoroalkyl acids in the American alligator (Alligator mississippiensis) at Merritt Island National Wildlife Refuge. AB - This study aimed to quantify concentrations of fifteen perfluoroalkyl acids (PFAAs) in the plasma of American alligators (Alligator mississippiensis) inhabiting wetlands surrounding the Kennedy Space Center (KSC) in Florida, USA located at Merritt Island National Wildlife Refuge (MINWR). Approximately 10 male and 10 female alligators (ntotal = 229) were sampled each month during 2008 and 2009 to determine if seasonal or spatial trends existed with PFAA burden. PFOS represented the highest plasma burden (median 185 ng/g) and PFHxS the second highest (median 7.96 ng/g). While no significant seasonal trends were observed, unique spatial trends emerged. Many of the measured PFAAs co-varied strongly together and similar trends were observed for PFOS, PFDA, PFUnA, and PFDoA, as well as for PFOA, PFHxS, PFNA, PFTriA, and PFTA, suggesting more than one source of PFAAs at MINWR. Higher concentrations of PFOS and the PFAAs that co-varied with PFOS were collected from animals around sites that included the Shuttle Landing Facility (SLF) fire house and the Neil Armstrong Operations and Checkout (O&C) retention pond, while higher concentrations of PFOA and the PFAA that co varied with PFOA were sampled from animals near the gun range and the old fire training facility. Sex-based differences and snout-vent length (SVL) correlations with PFAA burden were also investigated. PMID- 27689887 TI - Facile green synthesis of functional nanoscale zero-valent iron and studies of its activity toward ultrasound-enhanced decolorization of cationic dyes. AB - For the first time, an integrated green technology by coupling functional nanoscale zero-valent iron (NZVI) with ultrasound (US) was innovatively developed for the enhanced decolorization of malachite green (MG) and methylene blue (MB). The functional NZVI (TP-Fe) was successfully fabricated via a facile, one-step and environmentally-benign approach by directly introducing high pure tea polyphenol (TP), where TP contenting abundant epicatechin was employed as reductant, dispersant and capping agent. Note that neither additional extraction procedure nor protection gas was needed during the entire synthesis process. Affecting factors (including US frequency, initial pH, dye concentration, and reaction temperature) were investigated. Results show that TP-Fe exhibited enhanced activity, antioxidizability and stability over the reaction course, which could be attributed to the functionalization of TP on NZVI and the invigorating effect of US (i.e., improving the mass transfer rate, breaking up the aggregates of TP-Fe nanoparticles, and maintaining the TP-Fe surface activity). The kinetics for MG and MB decolorization by the TP-Fe/US system could be well described by a two-parameter pseudo-first-order decay model, and the activation energies of MG and MB decolorization in this new system were determined to be 21 kJ mol-1 and 24 kJ mol-1, respectively. In addition, according to the identified reaction products, a possible mechanism associated with MG and MB decolorization with the TP-Fe/US system was proposed. PMID- 27689888 TI - Copper-catalyzed activation of molecular oxygen for oxidative destruction of acetaminophen: The mechanism and superoxide-mediated cycling of copper species. AB - In this study, the commercial zero-valent copper (ZVC) was investigated to activate the molecular oxygen (O2) for the degradation of acetaminophen (ACT). 50 mg/L ACT could be completely decomposed within 4 h in the ZVC/air system at initial pH 3.0. The H2O2, hydroxyl radical (OH) and superoxide anion radical (O2 ) were identified as the main reactive oxygen species (ROSs) generated in the above reaction; however, only OH caused the decomposition and mineralization of ACT in the copper-catalyzed O2 activation process. In addition, the in-situ generated Cu+ from ZVC dissolution not only activated O2 to produce H2O2, but also initiated the decomposition of H2O2 to generate OH. Meanwhile, the H2O2 could also be partly decomposed into O2-, which served as a mediator for copper cycling by reduction of Cu2+ to Cu+ in the ZVC/air system. Therefore, OH could be continuously generated; and then ACT was effectively degraded. Additionally, the effect of solution pH and the dosage of ZVC were also investigated. As a result, this study indicated the key behavior of the O2- during Cu-catalyzed activation of O2, which further improved the understanding of O2 activation mechanism by zero-valent metals.

AB - Produced water (PW) is the largest liquid waste stream generated during the exploration and drilling process of both the conventional hydrocarbon based resources like crude oil and natural gas, as well as the new fossil resources like shale gas and coal bed methane. Resource management, efficient utilization of the water resources, and water purification protocols are the conventionally used treatment methods applied to either treat or utilize the generated PW. This review provides a comprehensive overview of these conventional PW treatment strategies with special emphasises on electrochemical treatment. Key considerations associated with these approaches for efficient treatment of PW are also discussed. After a thorough assessment of the salient features of these treatment platforms, we propose a new strategy of uniquely integrating bioelectrochemical processes with biological system for more effective PW treatment and management. PMID- 27689890 TI - Rattle-type magnetic mesoporous hollow carbon as a high-performance and reusable adsorbent for water treatment. AB - Rattle-type magnetic mesoporous hollow carbon (RMMHC) materials have shown great promise as adsorbents for water treatment. In this work, we report a surfactant free synthesis of RMMHC nanoparticles (NPs) using magnetite NPs as the core, tetrapropyl orthosilicate, resorcinol and formaldehyde to form the shell followed by carbonization and selective silica etching. The pore size, specific surface area and pore volume of RMMHC NPs can be tuned by varying the carbonization temperature (500, 700 and 900 degrees C). At the optimized temperature of 700 degrees C, the RMMHC NPs possess the highest specific surface area of 579 m2 g-1, the largest pore volume of 0.795 cm3 g-1, and the largest pore size of 7.6 nm among all three samples. The adsorption capacity of optimized RMMHC NPs towards di (2-ethylhexyl) phthalate (a model organic pollutant) reaches as high as 783.1 mg g-1. Taking advantage of the magnetic property, the adsorbents retain more than 87% of their initial adsorption capacity over five times' reuse. PMID- 27689891 TI - Simultaneous Quantification of Antioxidant Compounds in Phellinus igniarius Using Ultra Performance Liquid Chromatography-Photodiode Array Detection-Electrospray Ionization Tandem Mass Spectrometry. AB - Natural antioxidants are widely used in the life sciences. Phellinus igniarius is a historically used natural antioxidant containing a variety of active compounds. Phenols, particularly Inoscavin A and Hypholomine B, are found in the high concentrations. Better quantitative methods are needed to perform quality control in order to support further research of this mushroom. An ultra-performance liquid chromatography method coupled to photodiode-array detection and an electrospray ionization tandem mass spectrometry method (UPLC-PAD-MS) was developed to simultaneously quantify Inoscavin A and Hypholomine B levels in the medicinal fungus Phellinus igniarius. The two compounds were quantified using UPLC-PAD and UPLC-MS. The methods were accurate (mean accuracy for spiked matrix ranged from 101.5% to 105.8%), sensitive (limit of detection ranged from 0.28 to 1.14 mg L-1) and precise (the relative standard deviations ranged from 0.13 to 2.8%). Inoscavin A and Hypholomine B were purified using high-speed counter current chromatography (HSCCC), structural evaluated to meet the request of standard substances. UPLC separation was performed on a reversed-phase C18 column using gradient elution with acetonitrile and 0.1% formic acid over 10 min. The developed method was successfully applied to determine Inoscavin A and Hypholomine B in twelve Phellinus igniarius samples of different origins and the results showed that it was suitable for the analysis of these active components in Phellinus igniarius samples. PMID- 27689892 TI - High Throughput Analysis of Integron Gene Cassettes in Wastewater Environments. AB - Integrons are extensively targeted as a proxy for anthropogenic impact in the environment. We developed a novel high-throughput amplicon sequencing pipeline that enables characterization of thousands of integron gene cassette-associated reads, and applied it to acquire a comprehensive overview of gene cassette composition in effluents from wastewater treatment facilities across Europe. Between 38 100 and 172 995 reads per-sample were generated and functionally characterized by screening against nr, SEED, ARDB and beta-lactamase databases. Over 75% of the reads were characterized as hypothetical, but thousands were associated with toxin-antitoxin systems, DNA repair, cell membrane function, detoxification and aminoglycoside and beta-lactam resistance. Among the reads characterized as beta-lactamases, the carbapenemase blaOXA was dominant in most of the effluents, except for Cyprus and Israel where blaGES was also abundant. Quantitative PCR assessment of blaOXA and blaGES genes in the European effluents revealed similar trends to those displayed in the integron amplicon sequencing pipeline described above, corroborating the robustness of this method and suggesting that these integron-associated genes may be excellent targets for source tracking of effluents in downstream environments. Further application of the above analyses revealed several order-of-magnitude reductions in effluent associated beta-lactamase genes in effluent-saturated soils, suggesting marginal persistence in the soil microbiome. PMID- 27689893 TI - Using the Novel Method of Nonthermal Plasma To Add Cl Active Sites on Activated Carbon for Removal of Mercury from Flue Gas. AB - A new method using nonthermal plasma to add Cl active sites on activated carbon was proposed to improve the efficiency of activated carbon (AC) for removal of mercury from flue gas. The experiments were conducted via a lab-scale dielectric barrier discharge nonthermal plasma system and a vertical adsorption reactor. The results showed that the nonthermal plasma treatment with a small amount of Cl2 successfully added Cl active sites on AC and greatly increased the mercury removal efficiency of AC by chemisorption in a very short treatment time. The increase in Cl2 concentration for AC treatment promoted the efficiency of AC. The capacity of mercury adsorption positively correlated with the content of Cl2 for AC treatment, which depends on the number of Cl active sites on activated carbon. The treated AC maintained a high mercury removal efficiency within a temperature range of 30-210 degrees C. SO2 and H2O in flue gas inhibited the removal of mercury by AC, while HCl had a promotional effect. Scanning electron microscopy and X-ray photoelectron spectroscopy analysis indicated the chemisorption of mercury was attributed to the C-Cl groups generated on AC surfaces during Cl2 nonthermal plasma treatment. The C-Cl groups as active sites had strong adsorption energy for mercury, which converted elemental mercury to HgCl2. PMID- 27689894 TI - Does the development of executive functioning in infants born preterm benefit from maternal directiveness? AB - OBJECTIVE: Problems in early development of executive functioning may underlie the vulnerability and individual variability of infants born preterm for behavioral and learning problems. Parenting behaviors may aggravate or temper this increased risk for dysfunction. This study assessed how maternal parenting behaviors predict individual differences in early development of executive functioning in infants born preterm, and whether this varies with infant temperament, i.e., self-regulation. METHODS: Participants were 76 infants born preterm (<=36weeks' gestation and <2500g birth weight) and their mothers. Maternal sensitive responsiveness and directiveness were observed during a mother infant interaction situation at 7, 10 and 14months corrected age. At the same ages, executive functioning was measured using the A-not-B task. An infant self regulation questionnaire (IBQ-R) was completed by mothers at 7months. RESULTS: After controlling for perinatal risk factors, Multivariate Latent Growth Modeling showed that consistently higher levels of maternal directiveness predicted a stronger increase in A-not-B performance, which did not vary with infant self regulation. No relationship between maternal sensitive responsiveness and development in A-not-B performance in infants born preterm was found. CONCLUSIONS: These results suggest that preterm infants' early executive functioning development in the first year of life may benefit from a more and consistent directive approach by their mothers. These findings have important implications for early intervention programs aimed at facilitating preterm infants' development. PMID- 27689895 TI - Children's representations of another person's spatial perspective: Different strategies for different viewpoints? AB - The current study investigated development and strategy use of spatial perspective taking (i.e., the ability to represent how an object or array of objects looks from other viewpoints) in children between 8 and 12years of age. We examined this ability with a task requiring children to navigate a route through a model city of wooden blocks from a 90 degrees and 180 degrees rotated perspective. We tested two hypotheses. First, we hypothesized that children's perspective-taking skills increase during this age period and that this process is related to a co-occurring increase in working memory capacity. Results indeed showed clear age effects; accuracy and speed of perspective-taking performance were higher in the older age groups. Positive associations between perspective taking performance and working memory were observed. Second, we hypothesized that children, like adults, use a mental self-rotation strategy during spatial perspective taking. To confirm this hypothesis, children's performance should be better in the 90 degrees condition than in the 180 degrees condition of the task. Overall, the results did show the reversed pattern; children were less accurate, were slower, and committed more egocentric errors in the 90 degrees condition than in the 180 degrees condition. These findings support an alternative scenario in which children employ different strategies for different rotation angles. We propose that children mentally rotated their egocentric reference frame for 90 degrees rotations; for the 180 degrees rotations, they inverted the left-right and front-back axes without rotating their mental position. PMID- 27689896 TI - Atlas-based shape analysis and classification of retinal optical coherence tomography images using the functional shape (fshape) framework. AB - We propose a novel approach for quantitative shape variability analysis in retinal optical coherence tomography images using the functional shape (fshape) framework. The fshape framework uses surface geometry together with functional measures, such as retinal layer thickness defined on the layer surface, for registration across anatomical shapes. This is used to generate a population mean template of the geometry-function measures from each individual. Shape variability across multiple retinas can be measured by the geometrical deformation and functional residual between the template and each of the observations. To demonstrate the clinical relevance and application of the framework, we generated atlases of the inner layer surface and layer thickness of the Retinal Nerve Fiber Layer (RNFL) of glaucomatous and normal subjects, visualizing detailed spatial pattern of RNFL loss in glaucoma. Additionally, a regularized linear discriminant analysis classifier was used to automatically classify glaucoma, glaucoma-suspect, and control cases based on RNFL fshape metrics. PMID- 27689897 TI - Real-time target tracking of soft tissues in 3D ultrasound images based on robust visual information and mechanical simulation. AB - In this paper, we present a real-time approach that allows tracking deformable structures in 3D ultrasound sequences. Our method consists in obtaining the target displacements by combining robust dense motion estimation and mechanical model simulation. We perform evaluation of our method through simulated data, phantom data, and real-data. Results demonstrate that this novel approach has the advantage of providing correct motion estimation regarding different ultrasound shortcomings including speckle noise, large shadows and ultrasound gain variation. Furthermore, we show the good performance of our method with respect to state-of-the-art techniques by testing on the 3D databases provided by MICCAI CLUST'14 and CLUST'15 challenges. PMID- 27689898 TI - Hostility and telomere shortening among U.S. military veterans: Results from the National Health and Resilience in Veterans Study. AB - : Chronic disorders of aging are critical concerns for the U.S. veteran population, which is, on average, two decades older than the non-veteran population. Characterization of risk factors that may accelerate biological aging is important in identifying targets for prevention and intervention. In the current study, we analyzed data from a contemporary, and nationally representative sample of U.S. veterans to evaluate the relationship between a broad range of sociodemographic, military, and clinical variables, and peripheral telomere length, which is an indicator of biological age and linked to risk for aging-related disorders and mortality. Data from 468U.S. military veterans who participated in the National Health and Resilience in Veterans Study were analyzed. Telomere length was assessed from cells isolated from saliva using quantitative polymerase chain reaction methods. A multivariable binary logistic regression analysis was conducted to evaluate the relations between hostility and telomere length, while controlling for sociodemographic, military, and clinical variables. Greater scores on a measure of hostility were independently associated with telomere shortening, even after adjustment for a broad range of other variables (odds ratio [OR]=1.58, 95% confidence interval [CI]=1.15-2.18). Secondary analyses revealed that this association was driven by difficulties controlling anger (OR=1.72, 95%CI=1.14-2.61), which reflect the external manifestation of hostility, rather than aggressive urges or impulses. Hostility, particularly difficulties controlling anger, is associated with peripheral telomere shortening in U.S. military veterans. Prevention and treatment efforts designed to reduce hostility may help mitigate risk for accelerated cellular aging in this growing segment of the U.S. POPULATION: PMID- 27689899 TI - Sleep restriction alters plasma endocannabinoids concentrations before but not after exercise in humans. AB - Following binding to cannabinoid receptors, endocannabinoids regulate a variety of central nervous system processes including appetite and mood. Recent evidence suggests that the systemic release of these lipid metabolites can be altered by acute exercise and that their levels also vary across the 24-h sleep-wake cycle. The present study utilized a within-subject design (involving 16 normal-weight men) to determine whether daytime circulating endocannabinoid concentrations differ following three nights of partial sleep deprivation (4.25-h sleep opportunity, 2:45-7a.m. each night) vs. normal sleep (8.5-h sleep opportunity, 10:30p.m.-7a.m. each night), before and after an acute bout of ergometer cycling in the morning. In addition, subjective hunger and stress were measured. Pre exercise plasma concentrations of 2-arachidonoylglycerol (2AG) were 80% higher 1.5h after awakening (vs. normal sleep, p<0.05) when participants were sleep deprived. This coincided with increased hunger ratings (+25% vs. normal sleep, p<0.05). Moreover, plasma 2AG was elevated 15min post-exercise (+44%, p<0.05). Sleep duration did not however modulate this exercise-induced rise. Finally, subjective stress was generally lower on the day after three nights of short sleep vs. normal sleep, especially after exercise (p<0.05). Given that activation of the endocannabinoid system has been previously shown to acutely increase appetite and mood, our results could suggest that behavioral effects of acute sleep loss, such as increased hunger and transiently improved psychological state, may partially result from activation of this signaling pathway. In contrast, more pronounced exercise-induced elevations of endocannabinoids appear to be less affected by short sleep duration. PMID- 27689901 TI - The ability of athletes with long-standing groin pain to maintain a stable lumbopelvic position: A laboratory study. AB - OBJECTIVES: The ability to maintain a lumbopelvic position (LPP) was assessed in athletes with a history of long-standing groin pain (LSGP) and athletes without LSGP. DESIGN: Case-control study. SETTING: University motion analysis laboratory. PARTICIPANTS: Thirty male athletes-15 with a history of LSGP (>12 weeks) and 15 without. MAIN OUTCOME MEASURES: Maintenance of LPP was assessed using a pressure biofeedback unit (PBU) during supine single leg lift (SLL), single leg extension (SLE) and bent knee fallout (BKFO). Repeatability was assessed using intra-class correlation coefficients (ICC) and group differences analysed using MANOVA. RESULTS: Differences were detected between involved and uninvolved sides in the LSGP group during SLL (mean difference [md] = 9.82 mmHg, p < 0.01) and BKFO (md = 8.56 mmHg, p < 0.01) but not during SLE (md = 0.38 mmHg, p = 0.96). Between group differences were found during the SLL of the involved leg (md = 5.22 mmHg p = 0.034) and the BKFO of the uninvolved leg (md = 6.22 mmHg p = 0.017). Inter session reliability varied for the different movement tasks in both groups (ICC = 0.35-0.94). CONCLUSIONS: Ability to maintain LPP differed between the involved and uninvolved legs within the LSGP group and between the athletes with and without LSGP. Despite resolution of groin pain, altered control of lumbopelvic position existed with possible implications for later injury recurrence. PMID- 27689900 TI - Stress management, leukocyte transcriptional changes and breast cancer recurrence in a randomized trial: An exploratory analysis. AB - PURPOSE: Cognitive behavioral stress management (CBSM) is an empirically validated group-based psychosocial intervention. CBSM is related to decreased self-reported indicators of psychological adversity during breast cancer treatment and greater disease-free survival (DFS) vs. a control condition. This study examined relationships between CBSM, DFS, and a potential biobehavioral pathway linking these variables in breast cancer patients through a gene expression composite representing the leukocyte conserved transcriptional response to adversity (CTRA). DESIGN: Women with stage 0-IIIb breast cancer completed questionnaires and provided blood samples post-surgery. Participants were randomized to 10-week group-based CBSM or a psychoeducation control group and followed at 6 months, 12 months, and median 11 years. In total, 51 participants provided blood data for longitudinal analyses (CBSM n=28; Control n=23). Mixed model analyses examined CBSM effects on 6-12 month changes in CTRA expression (53 indicator genes representing pro-inflammatory, anti-viral and antibody production signaling). Cox regression models assessed the relationship between 6 and 12 month changes in CTRA expression and 11-year DFS. RESULTS: Patients randomized to CBSM showed attenuated 6-12 month change in CTRA gene expression, whereas patients randomized to control showed increased CTRA expression (p=0.014). Average DFS was 5.92 years (SD=3.90). Greater 6-12 month CTRA increases predicted shorter 11-year DFS controlling for covariates (p=0.007). CONCLUSIONS: CBSM attenuated CTRA gene expression during the initial year of breast cancer treatment. In turn, greater increases in CTRA gene expression predicted shorter long-term DFS. These findings identify a biobehavioral oncology pathway to examine in future work.

AB - A one-pot, three-component synthesis of alpha-pyridyl, alpha-substituted amino acid derivatives is described. The key transformation is a direct, precious-metal free heteroarylation of readily available, amino acid derived azlactones with electrophilically activated pyridine N-oxides. The resulting intermediates can be used directly as efficient acylating agents for a range of nucleophiles, leading to the heteroarylated amino acid derivatives in a single vessel. PMID- 27689904 TI - Anisotropic Dielectric Breakdown Strength of Single Crystal Hexagonal Boron Nitride. AB - Dielectric breakdown has historically been of great interest from the perspectives of fundamental physics and electrical reliability. However, to date, the anisotropy in the dielectric breakdown has not been discussed. Here, we report an anisotropic dielectric breakdown strength (EBD) for h-BN, which is used as an ideal substrate for two-dimensional (2D) material devices. Under a well controlled relative humidity, EBD values in the directions both normal and parallel to the c axis (EBD?c and EBD?c) were measured to be 3 and 12 MV/cm, respectively. When the crystal structure is changed from sp3 of cubic-BN (c-BN) to sp2 of h-BN, EBD?c for h-BN becomes smaller than that for c-BN, while EBD?c for h-BN drastically increases. Therefore, h-BN can possess a relatively high EBD concentrated only in the direction parallel to the c axis by conceding a weak bonding direction in the highly anisotropic crystal structure. This explains why the EBD?c for h-BN is higher than that for diamond. Moreover, the presented EBD value obtained from the high quality bulk h-BN crystal can be regarded as the standard for qualifying the crystallinity of h-BN layers grown via chemical vapor deposition for future electronic applications.

AB - Candida albicans is a commensal coloniser of most people and a pathogen of the immunocompromised or patients in which barriers that prevent dissemination have been disrupted. Both the commensal and pathogenic states involve regulation and adaptation to the host microenvironment. The pathogenic potential can be downregulated to sustain commensalism or upregulated to damage host tissue and avoid and subvert immune surveillance. In either case it seems as though the cell biology of this fungus has evolved to enable the establishment of different types of relationships with the human host. Here we summarise latest advances in the analysis of mechanisms that enable C. albicans to occupy different body sites whilst avoiding being eliminated by the sentinel activities of the human immune system. PMID- 27689906 TI - Aqueous Synthesis of (210) Oxygen-Terminated Defect-Free Hierarchical ZnO Particles and Their Heat Treatment for Enhanced Reactivity. AB - Controlled aqueous growth of 1 MUm flower-shaped ZnO particles with a hierarchical subset of exposed nanosheets represented by {210} crystal faces, followed by annealing at temperatures up to 1000 degrees C, is presented. The flower-shaped particles showed superior photocatalytic performance compared to the crystal faces of 20 nm ZnO nanoparticles. The photocatalytic reaction rate of the flower-shaped particles before annealing was 2.4 times higher per m2 compared with that of the nanoparticles with double specific surface area. Crystal surface defects and nanosized pores within the flower-shaped particles were revealed by porosity measurements and electron microscopy. A heat treatment at 400 degrees C was found to be optimal for removal of nanoporosity/surface defects and impurities while retaining the hierarchical superstructure. The heat treatment resulted in a photodegradation efficiency that increased by an additional 43%, although the specific surface area decreased from 16.7 to 13.0 m2g-1. The enhanced photocatalytic effect remained intact under both acidic and alkaline environments owing to the {210} crystal surfaces, which were less prone to dissolution than the nanoparticles. The photocatalytic performance relied on primarily three factors: the removal of surface impurities, the oxygen termination of the {210} crystal faces, and the promotion of charge carrier lifetime by removal of lattice defects acting as recombination centers. The synthesis presented is an entirely hydrocarbon- and surfactant-free ("green") preparation scheme, and the formation of the flower-shaped particles was favored solely by optimization of the reaction temperature after the correct nitrate salt precursor concentrations had been established. PMID- 27689905 TI - Enhanced non-invasive respiratory sampling from bottlenose dolphins for breath metabolomics measurements. AB - Chemical analysis of exhaled breath metabolites is an emerging alternative to traditional clinical testing for many physiological conditions. The main advantage of breath analysis is its inherent non-invasive nature and ease of sample collection. Therefore, there exists a great interest in further development of this method for both humans and animals. The physiology of cetaceans is exceptionally well suited for breath analysis due to their explosive breathing behavior and respiratory tract morphology. At the present time, breath analysis in cetaceans has very limited practical applications, in large part due to lack of widely adopted sampling device(s) and methodologies that are well standardized. Here, we present an optimized design and the operating principles of a portable apparatus for reproducible collection of exhaled breath condensate from small cetaceans, such as bottlenose dolphins (Tursiops truncatus). The device design is optimized to meet two criteria: standardized collection and preservation of information-rich metabolomic content of the biological sample, and animal comfort and ease of breath sample collection. The intent is to furnish a fully-benchmarked technology that can be widely adopted by researchers and conservationists to spur further developments of breath analysis applications for marine mammal health assessments. PMID- 27689907 TI - Irida-beta-ketoimines Derived from Hydrazines To Afford Metallapyrazoles or N-N Bond Cleavage: A Missing Metallacycle Disclosed by a Theoretical and Experimental Study. AB - Unprecedented metallapyrazoles [IrH2{Ph2P(o-C6H4)CNNHC(o-C6H4)PPh2}] (3) and [IrHCl{Ph2P(o-C6H4)CNNHC(o-C6H4)PPh2}] (4) were obtained by the reaction of the irida-beta-ketoimine [IrHCl{(PPh2(o-C6H4CO))(PPh2(o-C6H4CNNH2))H}] (2) in MeOH heated at reflux in the presence and absence of KOH, respectively. In solution, iridapyrazole 3 undergoes a dynamic process due to prototropic tautomerism with an experimental barrier for the exchange of DeltaGcoal? = 53.7 kJ mol-1. DFT calculations agreed with an intrapyrazole proton transfer process assisted by two water molecules (DeltaG = 63.1 kJ mol-1). An X-ray diffraction study on 4 indicated electron delocalization in the iridapyrazole ring. The reaction of the irida-beta-diketone [IrHCl{(PPh2(o-C6H4CO))2H}] (1) with H2NNRR' in aprotic solvents gave irida-beta-ketoimines [IrHCl{(PPh2(o-C6H4CO))(PPh2(o C6H4CNNRR'))H}] (R = R' = Me (5); R = H, R' = Ph (8)), which can undergo N-N bond cleavage to afford the acyl-amide complex [IrHCl(PPh2(o-C6H4CO))(PPh2(o C6H4C(O)N(CH3)2))-kappaP,kappaO] (6) or [IrHCl(PPh2(o-C6H4CO))(PPh2(o-C6H4CN) kappaP)(NH2NHPh-kappaNH2)] (9) containing o-(diphenylphosphine)benzonitrile and phenylhydrazine, respectively. From a CH2Cl2/CH3OH solution of 9 kept at -18 degrees C, single crystals of [IrHCl(PPh2(o-C6H4CO))(PPh2(o-C6H4CN) kappaP))(HN?NPh-kappaNH)] (10) containing o-(diphenylphosphine)benzonitrile and phenyldiazene were formed, as shown by X-ray diffraction. The reaction of 1 with methylhydrazine in methanol gave the hydrazine complex [IrCl(PPh2(o C6H4CO))2(NH2NH(CH3)-kappaNH2)] (7). Single-crystal X-ray diffraction analysis was performed on 6 and 7. PMID- 27689908 TI - Determination and evaluation of heavy metals in soils under two different greenhouse vegetable production systems in eastern China. AB - The evaluation of heavy metals (HMs) in greenhouse soils is crucial for both environmental monitoring and human health; thus, it is imperative to determine their concentrations, identify their sources and assess their potential risks. In this study, eight metals (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn) in 167 surface soils were investigated in two representative greenhouse vegetable systems of China: perennial solar greenhouse (SG) and seasonal plastic greenhouse (PG). The results indicated accumulations of Cd, Cu, Hg and Zn in the SG soils and Cd, Pb, Hg and Zn in the PG soils, with higher concentrations than the background values. In particular, Cd and Hg exhibited high levels of pollution under both GVP systems due to their positive Igeo values. Principle component analysis (PCA) and correlation analysis suggested that Cd, Cu, Hg and Zn in the SG soils and Cd, Hg and Zn in the PG soils were mainly related to intensive farming practices; Pb in the PG soils was significantly affected by atmospheric deposition. The results showed that soil characteristics, in particular soil organic matter, total nitrogen and total phosphorus, exerted significant influence on Hg, Cu, Cd, and Zn under the SG system. However, the HMs in the PG soils were weakly affected by soil properties. Overall, this study provides comparative research on the accumulation, potential risks and sources of HMs in two typical greenhouse soils in China, and our findings suggest that, Cd and Hg in both greenhouse soils could potentially represent environmental problems. PMID- 27689910 TI - Synthesis, Electrochemical Characterization, and Linear Free Energy Relationship of 1,3-Diphenyl-6-alkyl/arylfulvenes. AB - A series of 1,3-diphenyl-6-alkyl/arylfulvenes was prepared, and the electrochemical properties were investigated. The addition of phenyl groups about the fulvene raised the reduction potential and helped to stabilize the electrochemically generated radical anion. The addition of various functional groups onto the phenyl ring at the 6-position of 1,3,6-triphenylfulvene results in a linear free energy relationship between reduction potential and the Hammett substituent constant, sigma. Further extending the conjugation at the 6-position of 1,3-diphenyl-6-arylfulvenes increases the reversibility of the redox reactions, but does not appear to further stabilize the generated radical anion. This in-depth investigation provides evidence that the compounds studied may have utility in light-harvesting applications. PMID- 27689909 TI - Malaria - how this parasitic infection aids and abets EBV-associated Burkitt lymphomagenesis. AB - Burkitt lymphoma (BL) is >90% EBV-associated when this pediatric cancer is diagnosed in regions heavily burden by endemic Plasmodium falciparum malaria and thus has been geographically classified as endemic BL. The incidence of endemic BL is 10-fold higher compared to BL diagnosed in non-malarious regions of the world. The other forms of BL have been classified as sporadic BL which contain EBV in ~30% of cases and immunodeficiency BL which occurs in HIV-infected adults with ~40% of tumors containing EBV. Within malaria endemic regions, epidemiologic studies replicating Denis Burkitt's seminal observation continue to show differences in endemic BL incidence linked to intensity of malaria transmission. However, the mechanisms by which malaria contributes to B cell tumorigenesis have not been resolved to the point of designing cancer prevention strategies. The focus of this review is to summarize our current knowledge regarding the influence of prolonged, chronic malaria exposure on defects in immunosurveillance that would otherwise control persistent EBV infections. And thus, set the stage for ensuing mechanisms by which malaria could instigate B cell activation and aberrant activation-induced cytidine deaminase expression initiating somatic hypermutation and thereby increasing the likelihood of an Ig/Myc translocation, the hallmark of all BL tumors. Malaria appears to play multiple, sequential and simultaneous roles in endemic BL etiology; the complexity of these interactions are being revealed by applying computational methods to human immunology. Remaining questions yet to be addressed and prevention strategies will also be discussed. PMID- 27689911 TI - Electrochemically Induced Transformations of Vanadium Dioxide Nanocrystals. AB - Vanadium dioxide (VO2) undergoes significant optical, electronic, and structural changes as it transforms between the low-temperature monoclinic and high temperature rutile phases. Recently, alternative stimuli have been utilized to trigger insulator-to-metal transformations in VO2, including electrochemical gating. Here, we prepare and electrochemically reduce mesoporous films of VO2 nanocrystals, prepared from colloidally synthesized V2O3 nanocrystals that have been oxidatively annealed, in a three-electrode electrochemical cell. We observe a reversible transition between infrared transparent insulating phases and a darkened metallic phase by in situ visible-near-infrared spectroelectrochemistry and correlate these observations with structural and electronic changes monitored by X-ray absorption spectroscopy, X-ray diffraction, Raman spectroscopy, and conductivity measurements. An unexpected reversible transition from conductive, reduced monoclinic VO2 to an infrared-transparent insulating phase upon progressive electrochemical reduction is observed. This insulator-metal-insulator transition has not been reported in previous studies of electrochemically gated epitaxial VO2 films and is attributed to improved oxygen vacancy formation kinetics and diffusion due to the mesoporous nanocrystal film structure.

PMID- 27689912 TI - Antivirulence C-Mannosides as Antibiotic-Sparing, Oral Therapeutics for Urinary Tract Infections. AB - Gram-negative uropathogenic Escherichia coli (UPEC) bacteria are a causative pathogen of urinary tract infections (UTIs). Previously developed antivirulence inhibitors of the type 1 pilus adhesin, FimH, demonstrated oral activity in animal models of UTI but were found to have limited compound exposure due to the metabolic instability of the O-glycosidic bond (O-mannosides). Herein, we disclose that compounds having the O-glycosidic bond replaced with carbon linkages had improved stability and inhibitory activity against FimH. We report on the design, synthesis, and in vivo evaluation of this promising new class of carbon-linked C-mannosides that show improved pharmacokinetic (PK) properties relative to O-mannosides. Interestingly, we found that FimH binding is stereospecifically modulated by hydroxyl substitution on the methylene linker, where the R-hydroxy isomer has a 60-fold increase in potency. This new class of C mannoside antagonists have significantly increased compound exposure and, as a result, enhanced efficacy in mouse models of acute and chronic UTI. PMID- 27689914 TI - Can Neuroimaging Markers of Vascular Pathology Explain Cognitive Performance in Adults With Sickle Cell Anemia? A review of the Literature. AB - Adults with homozygous sickle cell anemia have, on average, lower cognitive function than unaffected controls. The mechanisms underlying cognitive deterioration in this population are poorly understood, but cerebral small vessel disease (CSVD) is likely to be implicated. We conducted a systematic review using the Prisma Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines of articles that included both measures of cognitive function and magnetic resonance imaging (MRI) neuroimaging markers of small vessel disease. While all five studies we identified reported small vessel disease by MRI, only two of them found a significant relationship between structural changes and cognitive performance. Differences in methodologies and small sample sizes likely accounted for the discrepancies between the studies. We conclude that while MRI is a valuable tool to identify markers of CSVD in this population, larger studies are needed to definitely establish a link between MRI-detectable abnormalities and cognitive function in sickle cell anemia. PMID- 27689916 TI - A novel puborectalis muscle artificial anal sphincter system with the module of sensory perception. AB - This article presents a novel puborectalis muscle artificial anal sphincter system (PM-AASS) with the module of sensory perception for treating severe faecal incontinence (FI). Due to the implantable feature of PM-AASS, this system applied low-power design and the total energy consumption could drop to 48.8 Ah/d. To reduce the injury of intestine and the pressure exerted on intestine, the actuator, including the structure of tings and the robot mechanism, of PM-AASS was presented and the middle ring was optimised. To realise the sensory perception, the intestinal flexible pressure sensors, comprising the radial sensors and the axial sensors, were designed. The sensors calibration showed the R-square of each fitting line were above 0.998, which presented a high goodness of fit and indicated we could figure out the pressure value with the analogue voltage captured by MCU. Through the in-vitro experiment, the results that the radial sensors were more relevant to the occlusion threshold while the axial sensors had more effect on the alarm threshold could be concluded. The practicability of the PM-AASS was verified by the results of the in-vivo experiment, which showed that the PM-AASS had the effect of improvement to the anorectal internal pressure. PMID- 27689915 TI - In silico frameworks for systematic pre-clinical screening of potential anti leukemia therapeutics. AB - INTRODUCTION: Leukemia is a collection of highly heterogeneous cancers that arise from neoplastic transformation and clonal expansion of immature hematopoietic cells. Post-treatment recurrence is high, especially among elderly patients, thus necessitating more effective treatment modalities. Development of novel anti leukemic compounds relies heavily on traditional in vitro screens which require extensive resources and time. Therefore, integration of in silico screens prior to experimental validation can improve the efficiency of pre-clinical drug development. Areas covered: This article reviews different methods and frameworks used to computationally screen for anti-leukemic agents. In particular, three approaches are discussed including molecular docking, transcriptomic integration, and network analysis. Expert opinion: Today's data deluge presents novel opportunities to develop computational tools and pipelines to screen for likely therapeutic candidates in the treatment of leukemia. Formal integration of these methodologies can accelerate and improve the efficiency of modern day anti leukemic drug discovery and ease the economic and healthcare burden associated with it. PMID- 27689917 TI - Generating Aptamers Interacting with Polymeric Surfaces for Biofunctionalization. AB - Common strategies for biofunctionalization of surfaces comprise the immobilization of bioactive molecules used as cell-binding ligands for cell recruitment. Besides covalent binding, multivalent noncovalent physical forces between substrate and ligand are an alternative way to equip surfaces with biomacromolecules. In this study, polymer binding ligands are screened by means of a DNA-based in vitro selection process. As candidate biomaterials poly(ether imide) (PEI), polystyrene, and poly[ethylene-co-(vinyl acetate)] are selected, due to their different chemical structure, but similar macroscopic interface properties, allowing physical interaction with nucleotide bases by varying valences. Multivalent interacting aptamers are successfully enriched by SELEX method and an area-wide surface functionalization is achieved, which can be used for further binding of bioactive molecules. In vitro selection against the polymers result in thymine-dominated aptamer binding motifs. The preferential interaction with thymine is attributed to its chemical structure, connected with a decreased electrostatic repulsion of the pi-system and the hydrophobic character maximizing entropy. The aptamer binding stability correlates with available valences for interaction, resulting in a more stable functionalization of PEI. PMID- 27689918 TI - Treatment response of ethyl pyruvate in a mouse model of chronic obstructive pulmonary disease studied by hyperpolarized 129 Xe MRI. AB - PURPOSE: The purpose of this work was to investigate disease progression and treatment response in a murine model of chronic obstructive pulmonary disease (COPD) using a preclinical hyperpolarized 129 Xe (HPXe) magnetic resonance imaging (MRI) strategy. METHODS: COPD phenotypes were induced in 32 mice by 10 weeks of exposure to cigarette smoke (CS) and lipopolysaccharide (LPS). Efficacy of ethyl pyruvate (EP), an anti-inflammatory drug, was investigated by administering EP to 16 of the 32 mice after 6 weeks of CS and LPS exposure. HPXe MRI was performed to monitor changes in pulmonary function during disease progression and pharmacological therapy. RESULTS: HPXe metrics of fractional ventilation and gas-exchange function were significantly reduced after 6 weeks of CS and LPS exposure compared to sham-instilled mice administered with saline (P < 0.05). After this observation, EP administration was started in 16 of the 32 mice and continued for 4 weeks. EP was found to improve HPXe MRI metrics to a similar level as in sham-instilled mice (P < 0.01). Histological analysis showed significant alveolar tissue destruction in the COPD group, but relatively normal alveolar structure in the EP and sham-instilled groups. CONCLUSION: This study demonstrates the potential efficacy of EP for COPD therapy, as assessed by a noninvasive, translatable 129 Xe MRI procedure. Magn Reson Med 78:721-729, 2017.

AB - DNA is increasingly used to engineer dynamic nanoscale circuits, structures, and motors, many of which rely on DNA strand-displacement reactions. The use of functional DNA sequences (e.g., aptamers, which bind to a wide range of ligands) in these reactions would potentially confer responsiveness on such devices, and integrate DNA computation with highly varied molecular stimuli. By using high throughput single-molecule FRET methods, we compared the kinetics of a putative aptamer-ligand and aptamer-complement strand-displacement reaction. We found that the ligands actively disrupted the DNA duplex in the presence of a DNA toehold in a similar manner to complementary DNA, with kinetic details specific to the aptamer structure, thus suggesting that the DNA strand-displacement concept can be extended to functional DNA-ligand systems. PMID- 27689919 TI - Tethered capsule endomicroscopy: from bench to bedside at a primary care practice. AB - Due to the relatively high cost and inconvenience of upper endoscopic biopsy and the rising incidence of esophageal adenocarcinoma, there is currently a need for an improved method for screening for Barrett's esophagus. Ideally, such a test would be applied in the primary care setting and patients referred to endoscopy if the result is suspicious for Barrett's. Tethered capsule endomicroscopy (TCE) is a recently developed technology that rapidly acquires microscopic images of the entire esophagus in unsedated subjects. Here, we present our first experience with clinical translation and feasibility of TCE in a primary care practice. The acceptance of the TCE device by the primary care clinical staff and patients shows the potential of this device to be useful as a screening tool for a broader population. PMID- 27689921 TI - Diagnosis of Vein of Galen aneurysmal malformation using fetal MRI. AB - PURPOSE: To present three fetal vein of Galen aneurysmal malformations (VGAMs), which were diagnosed through magnetic resonance imaging (MRI), and highlight these cardiovascular findings. MATERIALS AND METHODS: We retrospectively reviewed three fetuses with VGAM at 31, 32, and 33 weeks of gestation. Feeding arteries and draining veins were observed by MRI. Secondary changes in the brain and high output heart failure caused by high blood flow in the lesion were evaluated. Two fetuses were born, and neonatal MRI was performed. One fetus was terminated. RESULTS: A characteristic dilated structure in the midline of the brain presented in each fetus. The arteriovenous fistula led to anatomical brain changes such as in the hydrocephalus, dilated feeding vessels (one or more), jugular vein, and/or superior vena cava. Substantial brachiocephalic vessel dilation was observed in two fetuses. Following parturition, one baby had neonatal asphyxia and sinus thrombosis, and MRI revealed hypoxic-ischemic encephalopathy. Cardiomegaly was detected in all three cases. CONCLUSION: With a large field of view, fetal MRI can observe brain VGAM, as well as the heart and affected large vessels. It can determine hydrocephalus, ischemia, intracranial hemorrhage, and sinus thrombosis. Providing such information on the infant's entire body can aid clinicians in determining the most appropriate treatment. LEVEL OF EVIDENCE: 4 J. Magn. Reson. Imaging 2017;46:1535-1539. PMID- 27689923 TI - Cervical Spondylotic Myelopathy: Metabolite Changes in the Primary Motor Cortex after Surgery. AB - Purpose To characterize longitudinal metabolite alterations in the motor cortex of patients with cervical spondylotic myelopathy (CSM) by using proton magnetic resonance (MR) spectroscopy and to evaluate white matter integrity with diffusion tensor imaging in patients who are recovering neurologic function after decompression surgery. Materials and Methods Informed written consent was obtained for all procedures and the study was approved by Western University's Health Sciences Research Ethics Board. Twenty-eight patients with CSM and 10 healthy control subjects were prospectively recruited and underwent two separate 3-T MR imaging examinations 6 months apart. Patients with CSM underwent surgery after the first examination. N-acetylaspartate (NAA), an indicator of neuronal mitochondrial function, normalized to creatine (Cr) levels were measured from the motor cortex contralateral to the greater functional deficit side in the patient group and on both sides in the control group. Fractional anisotropy and mean diffusivity were measured by means of diffusion-tensor imaging in the white matter adjacent to the motor and sensory cortices of the hand and the entire cerebral white matter. Clinical data were analyzed by using Student t tests. Results In patients with CSM, NAA normalized to Cr (NAA/Cr) levels were significantly lower 6 months after surgery (1.48 +/- 0.08; P < .03) compared with preoperative levels (1.73 +/- 0.09), despite significant improvement in clinical questionnaire scores. Fractional anisotropy and mean diffusivity were the same (P > .05) between the patient and control groups in all measured regions at all time points. Conclusion NAA/Cr levels decreased in the motor cortex in patients with CSM 6 months after successful surgery. Intact white matter integrity with decreased NAA/Cr levels suggests that mitochondrial metabolic dysfunction persists after surgery.

PMID- 27689922 TI - Yield of CT Pulmonary Angiography in the Emergency Department When Providers Override Evidence-based Clinical Decision Support. AB - Purpose To determine the frequency of, and yield after, provider overrides of evidence-based clinical decision support (CDS) for ordering computed tomographic (CT) pulmonary angiography in the emergency department (ED). Materials and Methods This HIPAA-compliant, institutional review board-approved study was performed at a tertiary care, academic medical center ED with approximately 60 000 annual visits and included all patients who were suspected of having pulmonary embolism (PE) and who underwent CT pulmonary angiography between January 1, 2011, and August 31, 2013. The requirement to obtain informed consent was waived. Each CT order for pulmonary angiography was exposed to CDS on the basis of the Wells criteria. For patients with a Wells score of 4 or less, CDS alerts suggested d-dimer testing because acute PE is highly unlikely in these patients if d-dimer levels are normal. The yield of CT pulmonary angiography (number of positive PE diagnoses/total number of CT pulmonary angiographic examinations) was compared in patients in whom providers overrode CDS alerts (by performing CT pulmonary angiography in patients with a Wells score <=4 and a normal d-dimer level or no d-dimer testing) (override group) and those in whom providers followed Wells criteria (CT pulmonary angiography only in patients with Wells score >4 or <=4 with elevated d-dimer level) (adherent group). A validated natural language processing tool identified positive PE diagnoses, with subsegmental and/or indeterminate diagnoses removed by means of chart review. Statistical analysis was performed with the chi2 test, the Student t test, and logistic regression. Results Among 2993 CT pulmonary angiography studies in 2655 patients, 563 examinations had a Wells score of 4 or less but did not undergo d dimer testing and 26 had a Wells score of 4 or less and had normal d-dimer levels. The yield of CT pulmonary angiography was 4.2% in the override group (25 of 589 studies, none with a normal d-dimer level) and 11.2% in the adherent group (270 of 2404 studies) (P < .001). After adjustment for the risk factor differences between the two groups, the odds of an acute PE finding were 51.3% lower when providers overrode alerts than when they followed CDS guidelines. Comparison of the two groups including only patients unlikely to have PE led to similar results. Conclusion The odds of an acute PE finding in the ED when providers adhered to evidence presented in CDS were nearly double those seen when providers overrode CDS alerts. Most overrides were due to the lack of d-dimer testing in patients unlikely to have PE. (c) RSNA, 2016. PMID- 27689924 TI - Impact of in Vivo High-Field-Strength and Ultra-High-Field-Strength MR Imaging on DNA Double-Strand-Break Formation in Human Lymphocytes. AB - Purpose To determine the impact of different magnetic field strengths (1, 1.5, 3, and 7 T) and the effect of contrast agent on DNA double-strand-break (DSB) formation in patients undergoing magnetic resonance (MR) imaging. Materials and Methods This in vivo study was approved by the local ethics committee, and written informed consent was obtained from each patient. To analyze the level of DNA DSBs, peripheral blood mononuclear cells were isolated from blood samples drawn directly before, as well as 5 minutes and 30 minutes after MR imaging examination. After performing gammaH2AX immunofluorescence staining, DSBs were quantified with automated digital microscopy. MR group consisted of 43 patients (22 women, 21 men; mean age, 46.1 years; range, 20-77 years) and was further subdivided according to the applied field strength and administration of contrast agent. Additionally, 10 patients undergoing either unenhanced or contrast material-enhanced computed tomography (CT) served as positive control subjects. Statistical analysis was performed with Friedman test. Results Whereas DSBs in lymphocytes increased after CT exposure (before MR imaging: 0.14 foci per cell +/ 0.05; 5 minutes after: 0.26 foci per cell +/- 0.07; 30 minutes after: 0.24 foci per cell +/- 0.07; P <= .05), no alterations were observed in patients examined with MR imaging (before MR imaging: 0.13 foci per cell +/- 0.02; 5 minutes after: 0.12 foci per cell +/- 0.02; 30 minutes after: 0.11 foci per cell +/- 0.02; P > .05). Differentiated analysis of MR imaging subgroups again revealed no significant changes in gammaH2AX level. Conclusion Analysis of gammaH2AX foci showed no evidence of DSB induction after MR examination, independent of the applied field strength and administration of gadolinium-based contrast agent. PMID- 27689925 TI - Internal Hernia after Laparoscopic Roux-en-Y Gastric Bypass: Optimal CT Signs for Diagnosis and Clinical Decision Making. AB - Purpose To evaluate the accuracy of computed tomography (CT) for diagnosis of internal hernia (IH) in patients who have undergone laparoscopic Roux-en-Y gastric bypass and to develop decision tree models to optimize diagnostic accuracy. Materials and Methods This was a retrospective, ethics-approved study of patients who had undergone laparoscopic Roux-en-Y gastric bypass with surgically confirmed IH (n = 76) and without IH (n = 78). Two radiologists independently reviewed each examination for the following previously established CT signs of IH: mesenteric swirl, small-bowel obstruction (SBO), mushroom sign, clustered loops, hurricane eye, small bowel behind the superior mesenteric artery, and right-sided anastomosis. Radiologists also evaluated images for two new signs, superior mesenteric vein (SMV) "beaking" and "criss-cross" of the mesenteric vessels. Overall impressions for diagnosis of IH were recorded. Diagnostic accuracy and interobserver agreement were calculated, and multivariate recursive partitioning was performed to evaluate various decision tree models by using the CT signs. Results Accuracy and interobserver agreement regarding the nine CT signs of IH showed considerable variation. The best signs were mesenteric swirl (sensitivity and specificity, 86%-89% and 86%-90%, respectively; kappa = 0.74) and SMV beaking (sensitivity and specificity, 80%-88% and 94%-95%, respectively; kappa = 0.83). Overall reader impression yielded the highest sensitivity and specificity (96%-99% and 90%-99%, respectively; kappa = 0.79). The decision tree model with the highest overall accuracy and sensitivity included mesenteric swirl and SBO, with a diagnostic odds ratio of 154 (95% confidence interval [CI]: 146, 161), sensitivity of 96% (95% CI: 87%, 99%), and specificity of 87% (95% CI: 75%, 93%). The decision tree with the highest specificity included SMV beaking and SBO, with a diagnostic odds ratio of 105 (95% CI: 101, 109), sensitivity of 90% (95% CI: 79%, 95%), and specificity of 92% (95% CI: 83%, 97%). Conclusion The decision tree with the highest accuracy and sensitivity for diagnosis of IH included mesenteric swirl and SBO, the model with the highest specificity included SMV beaking and SBO, and the remaining signs showed lower accuracy and/or poor to fair interobserver agreement.

AB - The decrease in caries prevalence in many industrialized countries and the improved knowledge about the etiology and pathogenesis of caries have shifted the focus of caries therapy over the past decades toward less invasive approaches. Studies on caries progression indicate that it is generally quite slow in most patients today which should lead to a reconsideration of the practice of early invasive intervention. Today noninvasive (eg, fluorides) and microinvasive (occlusal sealing, proximal infiltration) therapeutic options that address etiological factors are gaining importance. The goal of these therapies is to heal or at least to slow down the progress of the disease. Noninvasive treatments are mainly related to controlling pathogenic factors (ie, sugar consumption) and enhancing protective factors (mainly oral hygiene and fluorides). Microinvasive treatments do not rely on the compliance of the patient as much, since these treatments include a resinous material that is applied to serve as a diffusion barrier for acids formed by cariogenic bacteria in the overlying plaque. To establish a minimum intervention treatment strategy for caries, the disease must be diagnosed at an early stage. In addition to assessing caries lesions in single teeth, individual risk factors need to be identified so that the underlying causes related to patients' behavioral patterns that led to the disease can be addressed as well. The patient should be informed about the scientific evidence related to the treatment choices in a participative atmosphere. Decision trees may help to make the range of findings comprehensible and the therapeutic shared decision-making process understandable to the patients.

AB - The replacement of a restoration is one of the most common procedures in dentistry. However, the criteria for such intervention, excluding catastrophic failure and persistent discomfort and pain, continue to be the subject of considerable debate. The decision-making process remains subjective on the part of the treating clinician, while the evidence base for refurbishment and repair rather than replacement for the management of defective and failing restorations continues to grow and strengthen. This article, prepared as an Academy of Operative Dentistry European Section consensus publication, reviews existing criteria for the replacement of restorations and encourages practitioners to shift, if not already doing so, to considering the replacement of a restoration as a last resort rather than as a prudent action to be taken if in any doubt about clinical acceptability. Further research in the area, spanning the risk assessment of defective and failing restorations and new diagnostic tools and processes, together with work to enhance the evidence base of restoration repair vs replacement, would be of immense value. PMID- 27689931 TI - Restoration Survival: Revisiting Patients' Risk Factors Through a Systematic Literature Review. AB - A literature review was conducted to investigate the influence of patient-related factors on restoration survival in posterior permanent teeth as well as to report the methods used to collect these factors. The selection of articles on longitudinal clinical studies investigating the survival of posterior restorations (except full crowns and temporary fillings) and including patient related factors was performed by applying predefined criteria. The review was organized into two parts, the first describing how patient factors were assessed in the studies (n=45) and the second presenting the statistical significance (n=27) and size of the effect (n=11) of these factors on restoration survival. Patient-related factors mentioned in the studies included age; gender; caries risk; caries activity/severity; decayed, missing, filled teeth; number of restorations; oral hygiene; and bruxism, among others. Sixteen studies included the patient age or age range in the analysis, which was found to be significant in 47% of the studies. Regarding gender, four of 17 reports found a significant effect on survival, showing more failures for men in three studies. The caries risk profile or related variables were included in the analysis of 15 studies, and a significant effect on survival was reported for high-caries-risk individuals (or related variables) in 67% of these studies. Bruxism was also found to influence restoration survival in three of six studies where this variable was investigated. Some issues were found regarding the reporting of methods used to classify patients according to risk and were thoroughly discussed. In view of the information gathered in this review, the assessment of patient factors along with other variables should become part of clinical studies investigating restoration survival, since several of these factors were shown to influence the failure of restorations, regardless of the material type. PMID- 27689932 TI - Professional Variability in Decision Making in Modern Dentistry: A Pilot Study. AB - Dental treatment planning is usually expected to take account of the individual patient's clinical risks and benefits. Ideally, the therapeutic choice for each and every patient should be based on adequate clinical diagnostics and risk assessment that facilitates stabilization of the patient's clinical condition as well as prevents further oral impairment. However, identification of the most suitable approach tends to become more and more challenging as the number of therapeutic alternatives continues to increase due to medical innovation. In this study, the challenge of decision making in modern dentistry is illustrated using the example of bounded edentulous spaces. Many therapeutic alternatives exist for such clinical scenarios, including a noninvasive monitoring approach, minimally invasive tooth recontouring, orthodontic and prosthodontic treatment, and implant placement. The findings of this pilot study highlight the utmost relevance of incorporating individual patients' needs and risks into clinical treatment planning and providing appropriate guidelines.

AB - PURPOSE: Directly radioiodinated [131I]-rituximab has been developed as a radioimmunotherapeutic agent in patients with CD20-positive B cell non-Hodgkin's lymphoma. However, there are concerns over its in vivo catabolism and deiodination. A novel radioiodination linker, N-(4-isothiocyanatobenzyl)-2-(3 (tributylstannyl)phenyl) acetamide (IBPA), was synthesized for the preparation of stable radioiodinated proteins. METHODS: The authors evaluated the potential of IBPA as a stable radioiodinated linker for rituximab. [125I]-IBPA was purified and conjugated with rituximab, and in vitro stability testing was performed in serum and liver microsomes. In vivo studies were performed after i.v. injection of [125I]-rituximab or [125I]-IBPA-rituximab to nude mice. RESULTS: In in vitro studies, [125I]-IBPA-rituximab was stable in serum and liver microsomes. In static scans, high radioactivity was evident in the thyroid following injection of [125I]-rituximab, but low radioactivity was seen in the thyroid following injection of [125I]-IBPA-rituximab. In biodistribution studies, radioactivity uptake in thyroid glands of [125I]-IBPA-rituximab was decreased by approximately sevenfold compared to [125I]-rituximab. In pharmacokinetics, the half-life of [125I]-rituximab was shorter than that of [125I]-IBPA-rituximab in plasma of nude mice. CONCLUSIONS: The authors demonstrate that [125I]-IBPA-rituximab is more stable to metabolic deiodination in vivo than is [125I]-rituximab. Radioiodination of rituximab using IBPA is thus preferable to direct labeling in terms of in vivo stability. PMID- 27689934 TI - Epigenetic Signatures at the RUNX2-P1 and Sp7 Gene Promoters Control Osteogenic Lineage Commitment of Umbilical Cord-Derived Mesenchymal Stem Cells. AB - Wharton's Jelly mesenchymal stem cells (WJ-MSCs) are an attractive potential source of multipotent stem cells for bone tissue replacement therapies. However, the molecular mechanisms involved in their osteogenic conversion are poorly understood. Particularly, epigenetic control operating at the promoter regions of the two master regulators of the osteogenic program, RUNX2/P57 and SP7 has not yet been described in WJ-MSCs. Via quantitative PCR profiling and chromatin immunoprecipitation (ChIP) studies, here we analyze the ability of WJ-MSCs to engage osteoblast lineage. In undifferentiated WJ-MSCs, RUNX2/P57 P1, and SP7 promoters are found deprived of significant levels of the histone post translational marks that are normally associated with transcriptionally active genes (H3ac, H3K27ac, and H3K4me3). Moreover, the RUNX2 P1 promoter lacks two relevant histone repressive marks (H3K9me3 and H3K27me3). Importantly, RUNX2 P1 promoter is found highly enriched in the H3K4me1 mark, which has been shown recently to mediate gene repression of key regulatory genes. Upon induction of WJ MSCs osteogenic differentiation, we found that RUNX2/P57, but not SP7 gene expression is strongly activated, in a process that is accompanied by enrichment of activating histone marks (H3K4me3, H3ac, and H3K27ac) at the P1 promoter region. Histone mark analysis showed that SP7 gene promoter is robustly enriched in epigenetic repressive marks that may explain its poor transcriptional response to osteoblast differentiating media. Together, these results point to critical regulatory steps during epigenetic control of WJ-MSCs osteogenic lineage commitment that are relevant for future applications in regenerative medicine. J.

PMID- 27689937 TI - Calibration bias of experimentally determined chlorine isotope enrichment factors: the need for a two-point calibration in compound-specific chlorine isotope analysis. AB - RATIONALE: The recent development of compound-specific online chlorine isotope analysis (37 Cl-CSIA) methods has fostered dual chlorine-carbon isotope studies to gain better insights into sources and environmental transformation reactions of chlorinated ethenes. One-point and two-point calibration schemes are currently used to convert raw data to the international delta37 ClSMOC scale, but a critical evaluation of best practices to arrive at reliable delta37 ClSMOC signatures and enrichment factors was missing and is presented here. METHODS: Aqueous solutions of neat perchloroethylene and trichloroethylene (TCE) and aqueous samples from a TCE biodegradation experiment with pure cultures of Desulfitobacterium hafniense Y51 were analysed for their chlorine isotope ratios using GC/qMS and GC/IRMS. The delta37 ClSMOC values were obtained using one-point and two-point calibration schemes. Chlorine isotope enrichment factors, epsilonCl , were calculated using both approaches and the corresponding bias of delta37 ClSMOC values introduced by the different types of calibration was determined. RESULTS: Different calibration methods resulted in significant differences (up to 30%) in both delta37 Cl signatures and epsilonCl values. CONCLUSIONS: Our results demonstrate that a two-point calibration together with comprehensive information on reference materials is indispensable and should become standard practice for reliable 37 Cl-CSIA of organic compounds.

AB - Mucin 1 (MUC1) peptide fused with Q11 (MUC1-Q11) having 35 residues has previously been shown to form amyloid fibrils. Using time-dependent and high resolution atomic force microscopy (AFM) imaging, it is revealed that the formation of individual MUC1-Q11 fibrils entails nucleation and extension at both ends. This process can be altered by local mechanical perturbations using AFM probes. This work reports two specific perturbations and outcomes. First, by increasing load while maintaining tip-surface contact, the fibrils are cut during the scan due to shearing. Growth of fibrils occurs at the newly exposed termini, following similar mechanism of the MUC1-Q11 nucleation growth. As a result, branched fibrils are seen on the surface whose orientation and length can be controlled by the nuclei orientation and reaction time. In contrast to the "one time-cut", fibrils can be continuously fragmented by modulation at sufficiently high amplitude. As a result, short and highly branched fibrils accumulate and pile on surfaces. Since the fibril formation and assembly of MUC1-Q11 can be impacted by local mechanical force, this approach offers a nonchemical and label free means to control the presentation of MUC1 epitopes, and has promising application in MUC1 fibril-based immunotherapy. PMID- 27689935 TI - Coordination-Driven Self-Assembly and Anticancer Potency Studies of Ruthenium Cobalt-Based Heterometallic Rectangles. AB - Three new cobalt-ruthenium heterometallic molecular rectangles, 1-3, were synthesized through the coordination-driven self-assembly of a new cobalt sandwich donor, (eta5 -Cp)Co[C4 -trans-Ph2 (4-Py)2 ] (L; Cp: cyclopentyl; Py: pyridine), and one of three dinuclear precursors, [(p-cymene)2 Ru2 (OO?OO)2 Cl2 ] [OO?OO: oxalato (A1 ), 5,8-dioxido-1,4-naphthoquinone (A2 ), or 6,11-dioxido-5,12 naphthacenedione (A3 )]. All of the self-assembled architectures were isolated in very good yield (92-94 %) and were fully characterized by spectroscopic analysis; the molecular structures of 2 and 3 were determined by single-crystal X-ray diffraction analysis. The anticancer activities of bimetallic rectangles 1-3 were evaluated with a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay, an autophagy assay, and Western blotting. Rectangles 1-3 showed higher cytotoxicity than doxorubicin in AGS human gastric carcinoma cells. In addition, the autophagic activities and apoptotic cell death ratios were increased in AGS cells by treatment with 1-3; the rectangles induced autophagosome formation by promoting LC3-I to LC3-II conversion and apoptotic cell death by increasing caspase-3/7 activity. Our results suggest that rectangles 1-3 induce gastric cancer cell death by modulating autophagy and apoptosis and that they have potential use as agents for the treatment of human gastric cancer.

AB - The self-diffusion coefficients of each component in mixtures of 1-butyl-3 methylimidazolium bis(trifluoromethanesulfonyl)imide ([Bmim][N(SO2 CF3 )2 ]) and acetonitrile were determined. The results suggest that the hydrodynamic boundary conditions change from "stick" to "slip" as the solvent composition transitions from "ionic liquid dissolved in acetonitrile" (chiIL <0.4) to "acetonitrile dissolved in ionic liquid" (chiIL >0.4). At higher chiIL , the acetonitrile species are affected by "cage" and "jump" events, as the acetonitrile molecules reside nearer to the charged centre on the ions than in the "non-polar" regions. The self-diffusion coefficients of hexan-1-amine, dipropylamine, 1-hexanol and dipropylether in mixtures of [Bmim][N(SO2 CF3 )2 ] and acetonitrile were determined. In general, the nitrogen-containing solutes were found to diffuse slower than the oxygen-containing solutes; this indicates that there are greater ionic liquid-N interactions than ionic liquid-O interactions. This work demonstrates that the self-diffusion coefficients of species can provide valuable information about solvent-solvent and solvent-solute interactions in mixtures containing an ionic liquid. PMID- 27689939 TI - Three-dimensional direct cell bioprinting for tissue engineering. AB - Bioprinting is a relatively new technology where living cells with or without biomaterials are printed layer-by-layer in order to create three-dimensional (3D) living structures. In this article, novel bioprinting methodologies are developed to fabricate 3D biological structures directly from computer models using live multicellular aggregates. Multicellular aggregates made out of at least two cell types from fibroblast, endothelial and smooth muscle cells are prepared and optimized. A novel bioprinting approach is proposed in order to continuously extrude cylindrical multicellular aggregates through the bioprinter's glass microcapillaries. The multicellular aggregates are first aspirated into a capillary and then compressed to form a continuous cylindrical multicellular bioink. To overcome surface tension-driven droplet formation, the required compression ratio is calculated. Based on the developed bioprinting strategies, multicellular aggregates and their support structures are bioprinted to form 3D tissue constructs with predefined shapes. The effect of the bioprinting process was examined for fusion, cell viability at different compression ratios, and f actin cytoskeletal organization. The results show that the bioprinted 3D constructs fuse rapidly and have high cell viability after printing. (c) 2016 Wiley Periodicals, Inc.

AB - Materials assembled by coordination interactions between naturally abundant polyphenols and metals are of interest for a wide range of applications, including crystallization, catalysis, and drug delivery. Such an interest has led to the development of thin films with tunable, dynamic properties, however, creating bulk materials remains a challenge. Reported here is a class of metallogels formed by direct gelation between inexpensive, naturally abundant tannic acid and group(IV) metal ions. The metallogels exhibit diverse properties, including self-healing and transparency, and can be doped with various materials by in situ co-gelation. The robustness and flexibility, combined with the ease, low cost, and scalability of the coordination-driven assembly process make these metallogels potential candidates for chemical, biomedical, and environmental applications.

AB - No ideal small-diameter vascular graft for widespread clinical application has yet been developed and current approaches still suffer from graft failure because of thrombosis or degeneration. Decellularized vascular grafts are a promising strategy as they preserve native vessel architecture while eliminating cell-based antigens and allow for autologous recellularization. In the present study, a functional in vivo rodent aortic transplantation model was used in order to evaluate the benefit of bioactive coating of decellularized vascular grafts with vascular endothelial growth factor (VEGF) conjugated to a temperature-sensitive aliphatic polyester hydrogel (HG). Luminal HG-VEGF coating persistence up to 4 weeks was confirmed in vivo by rhodamine-labelling. Doppler-sonography showed that the grafts were functional for up to 8 weeks in vivo. Histological and immunohistochemical analysis of the explanted grafts after 4 weeks and 8 weeks in vivo demonstrated significantly increased endothelium formation in the HG-VEGF group compared with the control group (luminal surface covered with single layered endothelium, 4 weeks: 64.8 +/- 7.6% vs. 40.4 +/- 8.3%, p = 0.025) as well as enhanced media recellularization (absolute cell count, 8 weeks: 22.1 +/- 13.0 vs. 3.2 +/- 3.6, p = 0.0039). However, HG-VEGF coating also led to increased neo intimal hyperplasia, resulting in a significantly increased intima-to-media ratio in the perianastomotic regions (intima-to-media ratio, 8 weeks: 1.61 +/- 0.17 vs. 0.93 +/- 0.09, p = 0.008; HG-VEGF vs. control). The findings indicate that HG VEGF coating has potential for the development of engineered small-diameter artificial grafts, although further research is needed to prevent neo-intimal hyperplasia.

AB - The present study aimed to: (i) estimate the prevalence of self-reported high fear of intra-oral injections, high blood-injury fear, and injection fear; (ii) explore the overlap between high fear of intra-oral injections and high fear of dental treatment; and (iii) evaluate the possible consequence of high fear of intra-oral injections in terms of avoidance of dental care. The sample included 1,441 subjects, 10- to 16-yr of age, attending elementary schools in a county of Norway. Data were collected using questionnaires that were completed in classrooms. The survey instruments used were the Intra-Oral Injection Fear-scale, the Children's Fear Survey Schedule-Dental Subscale, the Injection Phobia scale for children, and the Mutilation Questionnaire for children. In total, 13.9% of the children reported high intra-oral injection fear. A strong association was found between fear of intra-oral injections and dental fear. When an intra-oral injection was needed, 10.6% would avoid dental treatment. In multiple regression analysis, high intra-oral injection fear was found to be associated with avoidance of dental treatment (OR = 6.52; 95% CI: 3.99-10.67). It was concluded that high fear of intra-oral injections was prevalent and might lead to avoidance of necessary dental treatment. Hence, intra-oral injection fear should be addressed before treatment of dental fear. PMID- 27689944 TI - Metabolic health profile in young adults with Prader-Willi syndrome: results of a 2-year randomized, placebo-controlled, crossover GH trial. AB - CONTEXT: Patients with Prader-Willi syndrome (PWS) have an increased fat mass and decreased lean body mass. GH-treated young adults with PWS who have attained adult height benefit from continuation of growth hormone (GH) treatment, as GH maintained their improved body composition, whereas fat mass increased during the placebo period. Adults with PWS are predisposed to T2DM and cardiovascular disease. Whether GH affects metabolic health profile of this patient group is unknown. OBJECTIVE: To investigate the effects of GH vs placebo on metabolic health, in young adults with PWS who were GH-treated for many years during childhood and had attained adult height (AH). METHOD: A 2-year, randomized, double-blind, placebo-controlled crossover study with stratification for gender and BMI in 27 young adults with PWS. Intervention with GH (0.67 mg/m2 /day) and placebo, both for 1-year duration. RESULTS: Compared to placebo, GH treatment resulted in similar glucose and insulin levels during oral glucose tolerance test. Only fasting glucose and insulin were slightly higher during GH vs placebo (+0.2 mmol/l and +18.4 pmol/l), although both remained within normal ranges in both phases. Blood pressure and lipid profile were similar after GH vs placebo. At baseline (AH) and during GH, no patients had metabolic syndrome, while 1 developed it during placebo treatment. CONCLUSIONS: Growth hormone treatment has no adverse effects on metabolic health profile. Thus, GH-treated young adults with PWS who have attained AH benefit from continuation of GH treatment without safety concerns regarding metabolic health. PMID- 27689945 TI - Effect of Active Videogames on Underserved Children's Classroom Behaviors, Effort, and Fitness. AB - OBJECTIVE: The purpose of this study was to examine the effect of active videogames (AVGs) on underserved minority children's on-task classroom behavior, academic effort, and fitness. MATERIALS AND METHODS: A one group pre- and posttest repeated measures design was used. In Fall 2013, 95 fourth grade children (57 boys, 38 girls; 96% of minority) from three classes at an underserved urban elementary school participated in teacher-supervised AVG activities (e.g., Wii Sports, Xbox Just Dance). Specifically, students participated in a 50-minute weekly AVG program at school for 6 weeks. Children's academic effort was evaluated by classroom teachers using a validated scale that assessed activity, attention, conduct, and social/emotional behavior. Moreover, children's classroom behavior was observed immediately before and after each AVG session by trained researchers. Finally, cardiovascular fitness was also measured. RESULTS: A paired t-test was used to assess teacher-rated student effort, while one-way (gender) analysis of variance (ANOVA) with repeated measures was performed to analyze children's on-task classroom behavior. There was a significant effect on children's effort between the first (mean = 3.24, SD = 0.75) and last week (mean = 3.41, SD = 0.73) assessments, t = 2.42, P = 0.02. In addition, there was a significant effect on classroom behavior, F = 33.103, P < 0.01. In detail, children scored significantly higher on on-task behavior during the post-AVG observation (mean = 81.4, SD = 12.3) than seen during the pre AVG observation (mean = 69.8, SD = 14.9). However, no main effect was indicated for gender, F = 0.39, P = 0.54. No significant improvement in cardiovascular fitness was observed, although slight improvements were seen. CONCLUSION: Offering an AVG program at school could improve underserved minority children's classroom on-task behavior and academic effort. Future studies may include a control group to further confirm the effectiveness of AVG activities. Practical implications for educators and other stakeholders are provided. PMID- 27689946 TI - Expectations of Graduate Communication Skills in Professional Veterinary Practice. AB - Good communication skills are an important entry-level attribute of graduates of professional degrees. The inclusion of communication training within the curriculum can be problematic, particularly in programs with a high content load, such as veterinary science. This study examined the differences between the perceptions of students and qualified veterinarians with regards to the entry level communication skills required of new graduates in clinical practice. Surveys were distributed to students in each of the four year levels of the veterinary science degree at the University of Melbourne and to recent graduates and experienced veterinarians registered in Victoria, Australia. Respondents were asked to rank the relative importance of six different skill sets: knowledge base; medical and technical skills; surgical skills; verbal communication and interpersonal skills; written communication skills; and critical thinking and problem solving. They were then asked to rate the importance of specific communication skills for new graduate veterinarians. Veterinarians and students ranked verbal communication and interpersonal skills as the most important skill set for an entry-level veterinarian. Veterinarians considered many new graduates to be deficient in these skills. Students often felt they lacked confidence in this area. This has important implications for veterinary educators in terms of managing the expectations of students and improving the delivery of communication skills courses within the veterinary curriculum. PMID- 27689947 TI - Patients Without Borders: Using Telehealth to Provide an International Experience in Veterinary Global Health for Veterinary Students. AB - There is an increasing need to produce veterinarians with knowledge and critical thinking skills that will allow them to participate in veterinary global health equity delivery, particularly in the developing world, where many people remain dependent on animal-based agriculture for a living. This need for veterinarians trained in global health is reflected by the demand among students for greater exposure and education. At the same time, many students are held back from on site training in global health due to constraints of cost, time, or family obligations. The purpose of this article is to describe the use of a telemedicine approach to educating veterinary students at Tufts Cummings School of Veterinary Medicine. This approach simultaneously provides expert consultation and support for a pro bono hospital in the developing world. The development of a telemedicine teaching service is discussed, from initial ad hoc email consultation among friends and associates to a more formal use of store-and forward delivery of data along with real-time videoconferencing on a regular basis, termed tele-rounds. The practicalities of data delivery and exchange and best use of available bandwidth are also discussed, as this very mundane information is critical to efficient and useful tele-rounds. Students are able to participate in discussion of cases that they would never see in their usual clinical sphere and to become familiar with diagnostic and treatment approaches to these cases. By having the patient "virtually" brought to us, tele-rounds also decrease the usual carbon footprint of global health delivery. PMID- 27689948 TI - Professional Veterinary Programs' Perceptions and Experiences Pertaining to Emotional Support Animals and Service Animals, and Recommendations for Policy Development. AB - Given the unique nature of programs in professional veterinary medicine (PVM), the increasing numbers of students requesting accommodations for emotional support animals (ESAs) in higher education settings is of growing interest to student affairs and administrative staff in PVM settings. Since the legislation pertaining to this type of support animal differs from the laws governing disability service animals, colleges and universities now need to develop new policies and guidelines. Representatives from a sample of 28 PVM programs completed a survey about the prevalence of student requests for ESAs and service animals. PVM associate deans for academic affairs also reported their perceptions of this issue and the challenges these requests might pose within veterinary teaching laboratories and patient treatment areas. Responses indicated that approximately one third of PVM programs have received requests for ESAs (32.1%) in the last 2 years, 17.9% have had requests for psychiatric service animals, and 17.9% for other types of service animals. Despite this, most associate deans reported not having or not being aware of university or college policies pertaining to these issues. Most associate deans are interested in learning more about this topic. This paper provides general recommendations for establishing university or PVM program policies.

AB - Cutaneous T-cell lymphomas represent a group of malignant lymphoproliferative disorders characterised by the occurrence of a monoclonal population of T lymphocytes. Diagnosis of early stages of this disease is a difficult challenge for both the dermatologist and the dermatopathologist. With the aid of the polymerase chain reaction it is possible to amplify specific regions of the T cell receptor gamma gene. The amplification products can then be separated by denaturing gradient gel electrophoresis in order to detect a monoclonal population of T-lymphocytes in the infiltrate. We studied 4 patients with the clinicopathologic diagnosis of mycosis fungoides and 2 patients diagnosed as large plaque parapsoriasis. A monoclonal population was detected in 3 of the 4 mycosis fungoides cases and in 1 of the patients with large plaque parapsoriasis. This indicates that our analysis can help us establishing a diagnosis, and it can also help us to identify patients with a possible early stage of the disease, which clinically or histologically is not yet recognised as such.

AB - This work presents a multivariate methodology combining principal component analysis, the Mahalanobis distance and decision trees for the selection of process factors and their levels in early process development of generic molecules. It is applied to a high throughput study testing more than 200 conditions for the production of a biosimilar monoclonal antibody at microliter scale. The methodology provides the most important selection criteria for the process design in order to improve product quality towards the quality attributes of the originator molecule. Robustness of the selections is ensured by cross validation of each analysis step. The concluded selections are then successfully validated with an external data set. Finally, the results are compared to those obtained with a widely used software revealing similarities and clear advantages of the presented methodology.

AB - OBJECTIVE: To identify potential risk factors associated with rehospitalization among Medicare recipients with heart failure (HF) receiving telehomecare. MATERIALS AND METHODS: This study is a nonexperimental, cross-sectional secondary data analysis of the Centers for Medicare and Medicaid (CMS) mandated assessment called the Outcome and Assessment Information Set (OASIS)-C, provided by a large home care company. A total of 526 patients who received telehomecare from January 1, 2011 to August 31, 2013 were included in the analyses, which used multiple logistic regression. RESULTS: The overall rate of rehospitalization was 36% while patients were receiving telehomecare. Moderately frail health status (p = 0.01), the presence of severe pain (p = 0.01), the presence of dermatologic problems (p = 0.03), and independence in dressing one's lower body (compared to slightly dependent [p = 0.01] or mostly dependent patient groups [p = 0.02]) were identified as risk factors for rehospitalization. CONCLUSIONS: The risk factors identified from this study may be used to drive more effective telehomecare placements, and referrals for additional services among telehomecare patients with HF.

AB - Distinct cellular level of the Ca2+-binding chaperone calreticulin (CRT) is essential for correct embryonal cardiac development and postnatal function. However, CRT is also a potential autoantigen eliciting formation of antibodies (Ab), whose role is not yet clarified. Immunization with CRT leads to cardiac injury, while overexpression of CRT in cardiomyocytes induces dilated cardiomyopathy (DCM) in animals. Hence, we analysed levels of anti-CRT Ab and calreticulin in the sera of patients with idiopatic DCM and hypertrophic cardiomyopathy (HCM). ELISA and immunoblot using human recombinant CRT and Pepscan with synthetic, overlapping decapeptides of CRT were used to detect anti CRT Ab. Serum CRT concentration was tested by ELISA. Significantly increased levels of anti-CRT Ab of isotypes IgA (p < 0.001) and IgG (p < 0.05) were found in patients with both DCM (12/34 seropositive for IgA, 7/34 for IgG) and HCM (13/38 seropositive for IgA, 11/38 for IgG) against healthy controls (2/79 for IgA, 1/79 for IgG). Titration analysis in seropositive DCM and HCM patients documented anti-CRT Ab detected at 1/1600 dilution for IgG and 1/800 for IgA (and IgA1) and at least at 1/200 dilution for IgA2, IgG1, IgG2 and IgG3. Pepscan identified immunogenic CRT epitopes recognized by IgA and IgG Ab of these patients. Significantly increased levels of CRT relative to healthy controls were found in sera of patients with HCM (p < 0.01, 5/19). These data extend the knowledge of seroprevalence of anti-CRT Ab and CRT, and suggest possible involvement of autoimmune mechanisms directed to CRT in some forms of cardiomyopathies, which are clinically heterogeneous.

A Qualitative Study of Clinicians' Perspectives. AB - RATIONALE: Evidence-based clinical practice guidelines recommend physical activity for people with lung cancer, however evidence has not translated into clinical practice and the majority of patients do not meet recommended activity levels. OBJECTIVES: To identify factors (barriers and enablers) that influence clinicians' translation of the physical activity guidelines into practice. METHODS: Qualitative study involving 17 participants (three respiratory physicians, two thoracic surgeons, two oncologists, two nurses, and eight physical therapists) who were recruited using purposive sampling from five hospitals in Melbourne, Victoria, Australia. Nine semistructured interviews and a focus group were conducted, transcribed verbatim, and independently cross-checked by a second researcher. Thematic analysis was used to analyze data. MEASUREMENTS AND MAIN RESULTS: Five consistent themes emerged: (1) the clinicians perception of patient-related physical and psychological influences (including symptoms and comorbidities) that impact on patient's ability to perform regular physical activity; (2) the influence of the patient's past physical activity behavior and their perceived relevance and knowledge about physical activity; (3) the clinicians own knowledge and beliefs about physical activity; (4) workplace culture supporting or hindering physical activity; and (5) environmental and structural influences in the healthcare system (included clinicians time, staffing, protocols and services). Clinicians described potential strategies, including: (1) the opportunity for nurse practitioners to act as champions of regular physical activity and triage referrals for physical activity services; (2) opportunistically using the time when patients are in hospital after surgery to discuss physical activity; and (3) for all members of the multidisciplinary team to provide consistent messages to patients about the importance of physical activity. CONCLUSIONS: Key barriers to implementation of the physical activity guidelines in lung cancer are diverse and include both clinician- and healthcare system-related factors. A combined approach to target a number of these factors should be used to inform research, improve clinical services, and develop policies aiming to increase physical activity and improve survivorship outcomes for patients with lung cancer.

AB - We introduce a method for increasing the compatibility of human brain vascular pericyte (HBVP) cells on a glass substrate, based on wet transferred monolayer graphene without any treatment. As a novel material, graphene has key properties for incubating cells, such as chemical stability, transparency, appropriate roughness, hydrophobicity and high electrical conductivity. These outstanding properties of graphene were examined by Raman spectroscopy, water contact angle measurements and atomic force microscopy. The performance of this graphene-based implant was investigated by a cell compatibility test, comparing the growth rate of cells on the graphene surface and that on a bare glass substrate. After an incubation period of 72 h, the number of live HBVP cells on a graphene surface with an area of 1*1 mm2 was 1.83 times greater than that on the glass substrate.

PMID- 27689963 TI - Multicolor imaging in the diagnosis and follow up of type 2 acute macular neuroretinopathy. AB - PurposeTo study the usefulness of multicolor imaging (MC) photographs in addition to near infrared reflectance (NIR) and spectral domain optical coherence tomography (SD-OCT) in the detection and follow up of acute macular neuroretinopathy (AMN).Patients and methodsSix patients with a complaint of paracentral scotomas in at least one eye due to AMN were included. They underwent full ophthalmic examination and multimodal imaging including color fundus photographs, (SD-OCT), NIR, and MC at baseline and follow up.ResultsFour females and two males, aged 19-64 years, and eight eyes affected by AMN, were included. Acute phase SD-OCT in all patients confirmed the diagnosis of type 2 AMN with partial recovery of the outer retina in the convalescent phase. NIR and MC elicited in all cases hypo-reflective AMN lesions pointing toward the fovea. MC exhibited a higher contrast between the affected and the physiologic retina that slowly attenuated during the follow up showing a decrease in the hypo-reflectance of the lesions.ConclusionMC imaging was more detailed than fundus color photographs and as detailed as NIR in the detection of AMN. When available, MC imaging should complement SD-OCT and NIR in the diagnosis and follow up of this rare inflammatory condition that may be underdiagnosed. PMID- 27689965 TI - Maxillary distraction osteogenesis versus orthognathic surgery for cleft lip and palate patients. AB - BACKGROUND: Cleft lip and palate is one of the most common birth defects and can cause difficulties with feeding, speech and hearing, as well as psychosocial problems. Treatment of orofacial clefts is prolonged; it typically commences after birth and lasts until the child reaches adulthood or even into adulthood. Residual deformities, functional disturbances, or both, are frequently seen in adults with a repaired cleft. Conventional orthognathic surgery, such as Le Fort I osteotomy, is often performed for the correction of maxillary hypoplasia. An alternative intervention is distraction osteogenesis, which achieves bone lengthening by gradual mechanical distraction. OBJECTIVES: To provide evidence regarding the effects and long-term results of maxillary distraction osteogenesis compared to orthognathic surgery for the treatment of hypoplastic maxilla in people with cleft lip and palate. SEARCH METHODS: We searched the following electronic databases: Cochrane Oral Health's Trials Register (to 16 February 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2016, Issue 1), MEDLINE Ovid (1946 to 16 February 2016), Embase Ovid (1980 to 16 February 2016), LILACS BIREME (1982 to 16 February 2016), the US National Institutes of Health Ongoing Trials Register (ClinicalTrials.gov) (to 16 February 2016), and the World Health Organization (WHO) International Clinical Trials Registry Platform (to 16 February 2016). There were no restrictions regarding language or date of publication in the electronic searches. We performed handsearching of six speciality journals and we checked the reference lists of all trials identified for further studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing maxillary distraction osteogenesis to conventional Le Fort I osteotomy for the correction of cleft lip and palate maxillary hypoplasia in non-syndromic cleft patients aged 15 years or older. DATA COLLECTION AND ANALYSIS: Two review authors assessed studies for eligibility. Two review authors independently extracted data and assessed the risk of bias in the included studies. We contacted trial authors for clarification or missing information whenever possible. All standard methodological procedures expected by Cochrane were used. MAIN RESULTS: We found six publications involving a total of 47 participants requiring maxillary advancement of 4 mm to 10 mm. All of them related to a single trial performed between 2002 and 2008 at the University of Hong Kong, but not all of the publications reported outcomes from all 47 participants. The study compared maxillary distraction osteogenesis with orthognathic surgery, and included participants from 13 to 45 years of age.Results and conclusions should be interpreted with caution given the fact that this was a single trial at high risk of bias, with a small sample size.The main outcomes assessed were hard and soft tissue changes, skeletal relapse, effects on speech and velopharyngeal function, psychological status, and clinical morbidities.Both interventions produced notable hard and soft tissue improvements. Nevertheless, the distraction group demonstrated a greater maxillary advancement, evaluated as the advancement of Subspinale A-point: a mean difference of 4.40 mm (95% CI 0.24 to 8.56) was recorded two years postoperatively.Horizontal relapse of the maxilla was significantly less in the distraction osteogenesis group five years after surgery. A total forward movement of A-point of 2.27 mm was noted for the distraction group, whereas a backward movement of 2.53 mm was recorded for the osteotomy group (mean difference 4.8 mm, 95% CI 0.41 to 9.19).No statistically significant differences could be detected between the groups in speech outcomes, when evaluated through resonance (hypernasality) at 17 months postoperatively (RR 0.11, 95% CI 0.01 to 1.85) and nasal emissions at 17 months postoperatively (RR 3.00, 95% CI 0.14 to 66.53), or in velopharyngeal function at the same time point (RR 1.28, 95% CI 0.65 to 2.52).Maxillary distraction initially lowered social self-esteem at least until the distractors were removed, at three months postoperatively, compared to the osteotomy group, but this improved over time and the distraction group had higher satisfaction with life in the long term (two years after surgery) (MD 2.95, 95% CI 014 to 5.76).Adverse effects, in terms of clinical morbidities, included mainly occlusal relapse and mucosal infection, with the frequency being similar between groups (3/15 participants in the distraction osteogenesis group and 3/14 participants in the osteotomy group). There was no severe harm to any participant. AUTHORS' CONCLUSIONS: This review found only one small randomised controlled trial concerning the effectiveness of distraction osteogenesis compared to conventional orthognathic surgery. The available evidence is of very low quality, which indicates that further research is likely to change the estimate of the effect. Based on measured outcomes, distraction osteogenesis may produce more satisfactory results; however, further prospective research comprising assessment of a larger sample size with participants with different facial characteristics is required to confirm possible true differences between interventions. PMID- 27689964 TI - Subfoveal choroidal thickness as a predictor of central serous chorioretinopathy. AB - PurposeThe purpose of the study was to evaluate the role of subfoveal choroidal thickness (CT) measurements as a predictor for the course of central serous chorioretinopathy (CSC).Patients and methodsThirty-eight eyes of 33 patients with CSC were analyzed retrospectively. Key inclusion criteria were naive (acute or recurrent) CSC; a minimum of 12 months of follow up; and the availability of good quality enhanced depth imaging SD-OCT images at each visit. Eyes with changes suggestive of chronic CSC and history of any treatment were excluded. Collected data included demographic profile, visual acuity, subfoveal CT, central macular thickness (CMT), and treatment details. Univariate and multivariate analyses for association of baseline features with need for treatment were performed. On the basis of results of this analysis, the 38 eyes were divided into two groups: Group A (subfoveal CT<=356 MUm) and Group B (subfoveal CT>356 MUm).ResultsOn univariate analysis, the need for treatment had significantly positive correlation with duration of symptoms (P=0.02), negative correlation with the baseline CT (P<0.01), and no significant correlation with CMT (P=0.13). On multivariate regression analysis, only baseline CT had a statistically significant association with the need for treatment (odds ratio (OR), 0.989; CI, 0.979-0.999; P=0.048). Group A eyes were more likely to require treatment (Group A: 54.55%, 12 of 22 eyes; Group B: 18.75%, 3 of 16 eyes; OR: 5.2, 95% CI, 1.15 23.54; P=0.04). There was a significant decrease in subfoveal CT in Group B ( 105.62+/-108.91 MUm; P=0.002).ConclusionCSC with a subfoveal CT<=356 MUm is of chronic nature and is more likely to require treatment rather than observation. PMID- 27689966 TI - Single-Layer Halide Perovskite Light-Emitting Diodes with Sub-Band Gap Turn-On Voltage and High Brightness. AB - Charge-carrier injection into an emissive semiconductor thin film can result in electroluminescence and is generally achieved by using a multilayer device structure, which requires an electron-injection layer (EIL) between the cathode and the emissive layer and a hole-injection layer (HIL) between the anode and the emissive layer. The recent advancement of halide perovskite semiconductors opens up a new path to electroluminescent devices with a greatly simplified device structure. We report cesium lead tribromide light-emitting diodes (LEDs) without the aid of an EIL or HIL. These so-called single-layer LEDs have exhibited a sub band gap turn-on voltage. The devices obtained a brightness of 591 197 cd m-2 at 4.8 V, with an external quantum efficiency of 5.7% and a power efficiency of 14.1 lm W-1. Such an advancement demonstrates that very high efficiency of electron and hole injection can be obtained in perovskite LEDs even without using an EIL or HIL. PMID- 27689967 TI - Recent Advances in the Determination of Biogenic Amines in Food Samples by (U)HPLC. AB - The determination of biogenic amines (BAs) in food products stirs increasing interest because of the implications in toxicological and food quality issues. Apart from these aspects, in recent years, the relevance of BAs because of some organoleptic and descriptive concerns has been pointed out by several researchers. This overview aims at revising recent advances in the determination of BAs in food samples based on liquid chromatography. In particular, papers published in the past five years have been commented. Special attention has been paid to the great possibilities of ultrahigh-performance liquid chromatography and high-resolution mass spectrometry. With regard to applications, apart from the determination of BAs in a wide range of food matrices, novel lines of research focused on the characterization, classification, and authentication of food products based on chemometrics have also been discussed. PMID- 27689968 TI - Asymmetrically Functionalized Antibody-Gold Nanoparticle Conjugates to Form Stable Antigen-Assembled Dimers. AB - Biomolecular assays based on the aggregation of modified gold nanoparticles (AuNPs) have been developed to provide low detection limits and rapid results with a simple one-step, wash-free procedure. However, a relatively narrow dynamic range, low sensitivity, and poor precision due to time-sensitive readout limit the application of these assay platforms. In this work we synthesized asymmetrically functionalized antibody-AuNP conjugates that are rationally designed to overcome the limitations of aggregation-based immunoassays. Solid phase synthesis was used to chemically passivate the majority of the AuNP surface and restrict antibody immobilization into a small area of the AuNP surface. These asymmetric conjugates assembled into dimers with the addition of antigen and were stable for over 24 h. In contrast, conventional antibody-AuNP conjugates which are symmetrically modified with antibody assembled into large aggregates that continuously increased in size with the addition of target antigen. These results suggest that asymmetric antibody-AuNP conjugates have the potential to significantly improve the analytical performance of aggregation-based immunoassays. PMID- 27689970 TI - Enzymatic Synthesis of Glucose-Based Fatty Acid Esters in Bisolvent Systems Containing Ionic Liquids or Deep Eutectic Solvents. AB - Sugar fatty acid esters (SFAEs) are biocompatible nonionic surfactants with broad applications in food, cosmetic, and pharmaceutical industries. They can be synthesized enzymatically with many advantages over their chemical synthesis. In this study, SFAE synthesis was investigated by using two reactions: (1) transesterification of glucose with fatty acid vinyl esters and (2) esterification of methyl glucoside with fatty acids, catalyzed by Lipozyme TLIM and Novozym 435 respectively. Fourteen ionic liquids (ILs) and 14 deep eutectic solvents (DESs) were screened as solvents, and the bisolvent system composed of 1 hexyl-3-methylimidazolium trifluoromethylsulfonate ([HMIm][TfO]) and 2-methyl-2 butanol (2M2B) was the best for both reactions, yielding optimal productivities (769.6 and 397.5 umol/h/g, respectively) which are superior to those reported in the literature. Impacts of different reaction conditions were studied for both reactions. Response surface methodology (RSM) was employed to optimize the transesterification reaction. Results also demonstrated that as co-substrate, methyl glucoside yielded higher conversions than glucose, and that conversions increased with an increase in the chain length of the fatty acid moieties. DESs were poor solvents for the above reactions presumably due to their high viscosity and high polarity. PMID- 27689969 TI - An international randomised controlled trial to compare TARGeted Intraoperative radioTherapy (TARGIT) with conventional postoperative radiotherapy after breast conserving surgery for women with early-stage breast cancer (the TARGIT-A trial). AB - BACKGROUND: Based on our laboratory work and clinical trials we hypothesised that radiotherapy after lumpectomy for breast cancer could be restricted to the tumour bed. In collaboration with the industry we developed a new radiotherapy device and a new surgical operation for delivering single-dose radiation to the tumour bed - the tissues at highest risk of local recurrence. We named it TARGeted Intraoperative radioTherapy (TARGIT). From 1998 we confirmed its feasibility and safety in pilot studies. OBJECTIVE: To compare TARGIT within a risk-adapted approach with whole-breast external beam radiotherapy (EBRT) over several weeks. DESIGN: The TARGeted Intraoperative radioTherapy Alone (TARGIT-A) trial was a pragmatic, prospective, international, multicentre, non-inferiority, non-blinded, randomised (1 : 1 ratio) clinical trial. Originally, randomisation occurred before initial lumpectomy (prepathology) and, if allocated TARGIT, the patient received it during the lumpectomy. Subsequently, the postpathology stratum was added in which randomisation occurred after initial lumpectomy, allowing potentially easier logistics and a more stringent case selection, but which needed a reoperation to reopen the wound to give TARGIT as a delayed procedure. The risk-adapted approach meant that, in the experimental arm, if pre-specified unsuspected adverse factors were found postoperatively after receiving TARGIT, EBRT was recommended. Pragmatically, this reflected how TARGIT would be practised in the real world. SETTING: Thirty-three centres in 11 countries. PARTICIPANTS: Women who were aged >= 45 years with unifocal invasive ductal carcinoma preferably <= 3.5 cm in size. INTERVENTIONS: TARGIT within a risk-adapted approach and whole-breast EBRT. MAIN OUTCOME MEASURES: The primary outcome measure was absolute difference in local recurrence, with a non-inferiority margin of 2.5%. Secondary outcome measures included toxicity and breast cancer specific and non-breast-cancer mortality. RESULTS: In total, 3451 patients were recruited between March 2000 and June 2012. The following values are 5-year Kaplan-Meier rates for TARGIT compared with EBRT. There was no statistically significant difference in local recurrence between TARGIT and EBRT. TARGIT was non-inferior to EBRT overall [TARGIT 3.3%, 95% confidence interval (CI) 2.1% to 5.1% vs. EBRT 1.3%, 95% CI 0.7% to 2.5%; p = 0.04; Pnon-inferiority = 0.00000012] and in the prepathology stratum (n = 2298) when TARGIT was given concurrently with lumpectomy (TARGIT 2.1%, 95% CI 1.1% to 4.2% vs. EBRT 1.1%, 95% CI 0.5% to 2.5%; p = 0.31; Pnon-inferiority = 0.0000000013). With delayed TARGIT postpathology (n = 1153), the between-group difference was larger than 2.5% and non-inferiority was not established for this stratum (TARGIT 5.4%, 95% CI 3.0% to 9.7% vs. EBRT 1.7%, 95% CI 0.6% to 4.9%; p = 0.069; Pnon-inferiority = 0.06640]. The local recurrence-free survival was 93.9% (95% CI 90.9% to 95.9%) when TARGIT was given with lumpectomy compared with 92.5% (95% CI 89.7% to 94.6%) for EBRT (p = 0.35). In a planned subgroup analysis, progesterone receptor (PgR) status was found to be the only predictor of outcome: hormone-responsive patients (PgR positive) had similar 5-year local recurrence with TARGIT during lumpectomy (1.4%, 95% CI 0.5% to 3.9%) as with EBRT (1.2%, 95% CI 0.5% to 2.9%; p = 0.77). Grade 3 or 4 radiotherapy toxicity was significantly reduced with TARGIT. Overall, breast cancer mortality was much the same between groups (TARGIT 2.6%, 95% CI 1.5% to 4.3% vs. EBRT 1.9%, 95% CI 1.1% to 3.2%; p = 0.56) but there were significantly fewer non-breast-cancer deaths with TARGIT (1.4%, 95% CI 0.8% to 2.5% vs. 3.5%, 95% CI 2.3% to 5.2%; p = 0.0086), attributable to fewer deaths from cardiovascular causes and other cancers, leading to a trend in reduced overall mortality in the TARGIT arm (3.9%, 95% CI 2.7% to 5.8% vs. 5.3%, 95% CI 3.9% to 7.3%; p = 0.099]. Health economic analyses suggest that TARGIT was statistically significantly less costly than EBRT, produced similar quality adjusted life-years, had a positive incremental net monetary benefit that was borderline statistically significantly different from zero and had a probability of > 90% of being cost-effective. There appears to be little uncertainty in the point estimates, based on deterministic and probabilistic sensitivity analyses. If TARGIT were given instead of EBRT in suitable patients, it might potentially reduce costs to the health-care providers in the UK by L8-9.1 million each year. This does not include environmental, patient and societal costs. LIMITATIONS: The number of local recurrences is small but the number of events for local recurrence-free survival is not as small (TARGIT 57 vs. EBRT 59); occurrence of so few events (< 3.5%) also implies that both treatments are effective and any difference is unlikely to be large. Not all 3451 patients were followed up for 5 years; however, more than the number of patients required to answer the main trial question (n = 585) were followed up for > 5 years. CONCLUSIONS: For patients with breast cancer (women who are aged >= 45 years with hormone sensitive invasive ductal carcinoma that is up to 3.5 cm in size), TARGIT concurrent with lumpectomy within a risk-adapted approach is as effective as, safer than and less expensive than postoperative EBRT. FUTURE WORK: The analyses will be repeated with longer follow-up. Although this may not change the primary result, the larger number of events may confirm the effect on overall mortality and allow more detailed subgroup analyses. The TARGeted Intraoperative radioTherapy Boost (TARGIT-B) trial is testing whether or not a tumour bed boost given intraoperatively (TARGIT) boost is superior to a tumour bed boost given as part of postoperative EBRT.

AB - Beta adrenergic receptors are crucial for their role in rhythmic contraction of heart along with their role in the pathological conditions such as tachycardia and high risk of heart failure. Studies report that the levels of beta-1 adrenergic receptor tend to decrease by 50%, whereas, the levels of beta-2 adrenergic receptor remains constant during the risk of heart failure. Beta blockers-the antagonistic molecules for beta-adrenergic receptors, function by slowing the heart rate, which thereby allows the left ventricle to fill completely during tachycardia incidents and hence helps in blood pumping capacity of heart and reducing the risk of heart failure. In the present study, we investigate the potential of glycyrrhizic acid (GA) as a possible principal drug molecule for cardiac arrhythmias owing to its ability to induce reduction in the heart rate and blood pressure. We use in vitro and in silico approach to study GA's effect on beta adrenergic receptor along with an in vivo study to examine its effect on heart rate and blood pressure. Additionally, we explore GA's proficiency in eliciting an increase in the plasma levels of vasoactive intestinal peptide, which by dilating the blood vessel consequently, can be a crucial aid during the occurrence of a potential heart attack. Therefore, we propose GA as a potential principal drug molecule via its potential in modulating heart rate and blood pressure. PMID- 27689972 TI - CO Oxidation over Pd/ZrO2 Catalysts: Role of Support's Donor Sites. AB - A series of supported Pd/ZrO2 catalysts with Pd loading from 0.2 to 2 wt % was synthesized. The ZrO2 material prepared by a similar technique was used as a reference sample. The samples have been characterized by means of transmission electron microscopy (TEM), X-ray diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS), temperature-programmed reduction (TPR), testing reaction of ethane hydrogenolysis (HGE), N2 adsorption, and electron paramagnetic resonance (EPR) spectroscopy. 1,3,5-trinitrobenzene was used as a probe molecule for the EPR spin probe method. The catalytic performance of samples was tested in the model reaction of CO oxidation. It was shown that the concentration of donor sites of support measured by EPR spin probe correlates with catalytic behavior during light-off tests. Low concentration of donor sites on a support's surface was found to be caused by the presence of the specific surface defects that are related to existence of coordinately unsaturated structures.

AB - To design new compounds suitable as starting points for anticancer drug development, we have synthesized a novel series of benzoxazoles with pharmaceutically advantageous piperazine and fluorine moieties attached to them. The newly synthesized benzoxazoles and their corresponding precursors were evaluated for cytotoxicity on human A-549 lung carcinoma cells and non-cancer HepaRG hepatocyes. Some of these new benzoxazoles show potential anticancer activity, while two of the intermediates show lung cancer selective properties at low concentrations where healthy cells are unaffected, indicating a selectivity window for anticancer compounds. PMID- 27689974 TI - Cordycepin Induces Apoptosis and Inhibits Proliferation of Human Lung Cancer Cell Line H1975 via Inhibiting the Phosphorylation of EGFR. AB - Cordycepin is an active component of the traditional Chinese medicine Cordyceps sinensis and Cordyceps militaris with notable anticancer activity. Though the prominent inhibitory activity was reported in different kinds of cancer cell lines, the concrete mechanisms remain elusive. It was reported that cordycepin could be converted into tri-phosphates in vivo to confuse a number of enzymes and interfere the normal cell function. For the inhibitory mechanism of EGFR inhibitors and the structure similarity of ATP and tri-phosphated cordycepin, human lung cancer cell line H1975 was employed to investigate the inhibitory effect of cordycepin. The results showed that cordycepin could inhibit cell proliferation and induce apoptosis in a dose-dependent manner. Cell cycle analysis revealed that H1975 cells could be arrested at the G0/G1 phase after cordycepin treatment. The expression levels of apoptosis-related protein Caspase 3 and Bcl-2 and phosphorylated expression levels of EGFR, AKT and ERK1/2 were all decreased compared with the control group stimulated with EGF. However, the protein expression levels of proapoptotic protein Bax and cleaved caspase-3 were increased. These results implied that cordycepin could inhibit cell proliferation and induce apoptosis via the EGFR signaling pathway. Our results indicated that there was potential to seek a novel EGFR inhibitor from cordycepin and its chemical derivatives. PMID- 27689975 TI - Phytochemical Compositions of Immature Wheat Bran, and Its Antioxidant Capacity, Cell Growth Inhibition, and Apoptosis Induction through Tumor Suppressor Gene. AB - The purpose of this study was to investigate the phytochemical compositions and antioxidant capacity, cell growth inhibition, and apoptosis induction in extracts of immature wheat bran. Immature wheat bran (IWB) was obtained from immature wheat harvested 10 days earlier than mature wheat. The phytochemical compositions of bran extract samples were analyzed by ultra-high performance liquid chromatography. The total ferulic acid (3.09 mg/g) and p-coumaric acid (75 ug/g) in IWB were significantly higher than in mature wheat bran (MWB, ferulic acid: 1.79 mg/g; p-coumaric acid: 55 ug/g). The oxygen radical absorbance capacity (ORAC: 327 uM Trolox equivalents (TE)/g) and cellular antioxidant activity (CAA: 4.59 uM Quercetin equivalents (QE)/g) of the IWB were higher than those of the MWB (ORAC: 281 uM TE/g; CAA: 0.63 uM QE/g). When assessing cell proliferation, the IWB extracts resulted in the lowest EC50 values against HT-29 (18.9 mg/mL), Caco-2 (7.74 mg/mL), and HeLa cells (8.17 mg/mL) among bran extract samples. Additionally, the IWB extracts increased the gene expression of p53 and PTEN (tumor suppressor genes) in HT-29 cells, indicating inhibited cell growth and induced apoptosis through tumor suppressor genes. PMID- 27689976 TI - Structural Characterization of the Avidin Interactions with Fluorescent Pyrene Conjugates: 1-Biotinylpyrene and 1-Desthiobiotinylpyrene. AB - Avidin is a tetrameric protein that belongs to the calycin superfamily. It has been studied mainly because of its extraordinary affinity to biotin, which led to a wide range of applications based on the avidin-biotin system. In the present study, we report the first crystal structures of avidin in a complex with two novel fluorescent pyrene derivatives: 1-biotinylpyrene (B9P) and 1 desthiobiotinylpyrene (D9P). The crystal structures were solved by molecular replacement using the coordinates of avidin molecule as a starting model and the final models of avidin/B9P and avidin/D9P were refined to resolutions of 2.0 A and 2.1 A, respectively. Our data reveal changes in loop conformation as well as in overall fold and quaternary arrangement of the avidin upon the binding of these fluorescent probes. Moreover, the crystal structures allowed analysis of the details of the interactions between the protein and the pyrene derivatives. Structural description of the complexes will contribute to the design of conjugates for expanding the capabilities of avidin-biotin technology.

AB - Origins-of-life research requires searching for a plausible transition from simple chemicals to larger macromolecules that can both hold information and catalyze their own production. We have previously shown that some group I intron ribozymes possess the ability to help synthesize other ribozyme genotypes by recombination reactions in small networks in an autocatalytic fashion. By simplifying these recombination reactions, using fluorescent anisotropy, we quantified the thermodynamic binding strength between two nucleotides of two group I intron RNA fragments for all 16 possible genotype combinations. We provide evidence that the binding strength (KD) between the 3-nucleotide internal guide sequence (IGS) of one ribozyme and its complement in another is correlated to the catalytic ability of the ribozyme. This work demonstrates that one can begin to deconstruct the thermodynamic basis of information in prebiotic RNA systems. PMID- 27689978 TI - Identification of the Main Intermediate Precursor of l-Ergothioneine Biosynthesis in Human Biological Specimens. AB - A capillary electrophoresis coupled to tandem mass spectrometry (CE-MS/MS) has been used to make a qualitative determination of hercynine-the main precursor of l-ergothioneine biosynthesis-in some key human biological specimens, such as urine, whole blood, plasma, and saliva. From semiquantitative analysis results, the highest concentrations of hercynine were detected in saliva and whole blood, whereas much lower concentrations were measured in urine and plasma. Whole blood was the biological matrix with the highest concentration of l-ergothioneine followed by plasma, saliva, and urine. The antioxidant effects attributed to l ergothioneine, along with its peculiar antioxidant mechanism, offer a possible explanation for the presence of the hercynine, as well as its concentration, in the considered biological matrices.

AB - The Pd-catalyzed direct alkylation of H-phosphinic acids and hypophosphorous acid with allylic/benzylic alcohols has been described previously. Here, the extension of this methodology to H-phosphinate esters is presented. The new reaction appears general, although its scope is narrower than with the acids, and its mechanism is likely different. Various alcohols are examined in their reaction with phosphinylidene compounds R1R2P(O)H. PMID- 27689980 TI - Advances in Organic and Organic-Inorganic Hybrid Polymeric Supports for Catalytic Applications. AB - In this review, the most recent advances (2014-2016) on the synthesis of new polymer-supported catalysts are reported, focusing the attention on the synthetic strategies developed for their preparation. The polymer-supported catalysts examined will be organic-based polymers and organic-inorganic hybrids and will include, among others, polystyrenes, poly-ionic liquids, chiral ionic polymers, dendrimers, carbon nanotubes, as well as silica and halloysite-based catalysts. Selected examples will show the synthesis and application in the field of organocatalysis and metal-based catalysis both for non-asymmetric and asymmetric transformations.

AB - Lawsonia inermis Linn (Lythraceae), also known as henna, is a small shrub or tree distributed throughout Taiwan's Lanyu Island, in North Africa, and in Australia. Its leaves are used as a folk medicine for the treatment of external hemorrhage and fingernail abscesses. Investigation of the ethyl acetate (EtOAc)-soluble fractions from methanol extract of the aerial part of Lawsonia inermis has led to the isolation of a new diphenol, (Z)-4,4'-(prop-1-ene-1,3-diyl)diphenol (1), two new isocoumarin carbonates, inermiscarbonates A (2) and B (3), and six known compounds, 4'-hydroxyflavanone (4), apigenine (5), kampferol (6), luteolin (7), quercetin (8), and (-)-catechin (9). Their structures were determined by detailed analysis of spectroscopic data and comparison with the data of known analogues. Compounds 1 and 4-9 were evaluated for the inhibition of nitric oxide production in lipopolysaccharide (LPS)-stimulated product of nitrite in RAW 264.7 cells with IC50 values of 5.63, 15.72, 8.67, 6.67, 6.17, 7.61, and 14.52 MUg/mL, respectively. PMID- 27689983 TI - Catalytic Synthesis of a New Series of Alkyl Uronates and Evaluation of Their Physicochemical Properties. AB - Large quantities (>3 g) of a new series of alkyl uronates were synthesized in two steps from commercial methyl hexopyranosides. Firstly, several tens of grams of free methyl alpha-d-glucopyranoside were selectively and quantitatively oxidized into corresponding sodium uronate using 2,2,6,6-tetramethyl-1-piperidinyloxy free radical (TEMPO)-catalyzed oxidation. Hydrophobic chains of different length were then introduced by acid-mediated esterification with fatty alcohols (ethyl to lauryl alcohol) leading to the desired alkyl glucuronates with moderate to good yields (49%-72%). The methodology was successfully applied to methyl alpha-d mannopyranoside and methyl beta-d-galactopyranoside. Physicochemical properties, such as critical micelle concentration (CMC), equilibrium surface tension at CMC (gammacmc), solubility, and Krafft temperature were measured, and the effect of structural modifications on surface active properties and micelle formation was discussed.

AB - Melanin plays an important role in protecting the skin against ultraviolet light and is responsible for skin color. However, overproduction of melanin is related to several skin disorders, such as age spots, freckles, cafe au lait spots, Becker's nevus and other hyperpigmentation syndromes. The aim of this study was to identify the effects of kaempferol-7-O-beta-d-glucuronide (K7G) and tilianin, isolated from Cryptotaenia japonica, on melanogenesis and their mechanisms of action in murine B16 melanoma cells. The alpha-melanocyte-stimulating hormone (alpha-MSH)-induced melanin production was significantly inhibited by K7G and tilianin in a dose-dependent manner. The effects of these compounds on the signaling pathway of melanogenesis were examined. K7G and tilianin downregulated the expression of microphthalmia-associated transcription factor (MITF) and melanocyte-specific enzymes, i.e., tyrosinase and TRP1. These compounds also inhibited the phosphorylation of cyclic adenosine monophosphate (cAMP)-response element binding protein (CREB) in a dose-dependent manner. In addition, these compounds increased the phosphorylation of extracellular signal-regulated kinase (ERK) but decreased the phosphorylation of c-Jun N-terminal kinase (JNK) in B16 cells. Based on the above results, the anti-melanogenic effects of these compounds are caused by suppression of the MAPK signaling pathway through the down-regulation of alpha-MSH-induced CREB accumulation. This finding suggests that K7G and tilianin may be good candidates for further research to develop therapeutic agents for hyperpigmentation diseases. PMID- 27689984 TI - Flavonoid Interaction with a Chitinase from Grape Berry Skin: Protein Identification and Modulation of the Enzymatic Activity. AB - In the present study, an antibody raised against a peptide sequence of rat bilitranslocase (anti-peptide Ab) was tested on microsomal proteins obtained from red grape berry skin. Previously, this antibody had demonstrated to recognize plant membrane proteins associated with flavonoid binding and transport. Immuno proteomic assays identified a number of proteins reacting with this particular antibody, suggesting that the flavonoid binding and interaction may be extended not only to carriers of these molecules, but also to enzymes with very different functions. One of these proteins is a pathogenesis-related (PR) class IV chitinase, whose in vitro chitinolytic activity was modulated by two of the most representative flavonoids of grape, quercetin and catechin, as assessed by both spectrophotometric and fluorimetric assays in grape microsomes and commercial enzyme preparations. The effect of these flavonoids on the catalysis and its kinetic parameters was also evaluated, evidencing that they determine a hormetic dose-dependent response. These results highlight the importance of flavonoids not only as antioxidants or antimicrobial effectors, but also as modulators of plant growth and stress response. Implications of the present suggestion are here discussed in the light of environment and pesticide-reduction concerns. PMID- 27689985 TI - Beneficial Effects of Tea and the Green Tea Catechin Epigallocatechin-3-gallate on Obesity. AB - Green tea has been shown to have beneficial effects against cancer, obesity, atherosclerosis, diabetes, bacterial and viral infections, and dental caries. The catechin (-)-epigallocatechin-3-gallate (EGCG) has shown the highest biological activity among green tea catechins (GTCs) in most of the studies. While several epidemiological studies have shown the beneficial effects of tea and GTCs on obesity, some studies have failed to do this. In addition, a large number of interventional clinical studies have shown these favorable effects, and cellular and animal experiments have supported those findings, and revealed the underlying anti-obesity mechanisms. One of the mechanisms is enhanced cellular production of reactive oxygen species, which is mediated through the pro-oxidant action of EGCG, leading to the activation of adenosine monophosphate-activated protein kinase, which suppresses gene and protein expression of enzymes and transcription factors involved in adipogenesis and lipogenesis, and stimulates those involved in lipolysis. Recently, scientific evidence supporting the beneficial anti obesity effects of green tea and GTCs has been increasing. However, future investigations are still required to clarify the reasons for the inconsistent results reported in the human studies; to achieve this, careful adjustment of confounding factors will be required. PMID- 27689986 TI - Traceability of Satsuma Mandarin (Citrus unshiu Marc.) Honey through Nectar/Honey Sac/Honey Pathways of the Headspace, Volatiles, and Semi-Volatiles: Chemical Markers. AB - Headspace solid-phase microextraction (HS-SPME) and ultrasonic solvent extraction (USE), followed by GC-MS/FID, were applied for monitoring the nectar (NE)/honey sac (HoS)/honey (HO) pathways of the headspace, volatiles, and semi-volatiles. The major NE (4 varieties of Citrus unshiu) headspace compounds were linalool, alpha-terpineol, 1H-indole, methyl anthranilate, and phenylacetonitrile. Corresponding extracts contained, among others, 1H-indole, methyl anthranilate, 1,3-dihydro-2H-indol-2-one and caffeine. The major HoS headspace compounds were linalool, alpha-terpineol, 1,8-cineole, 1H-indole, methyl anthranilate, and cis jasmone. Characteristic compounds from HoS extract were caffeine, 1H-indole, 1,3 dihydro-2H-indol-2-one, methyl anthranilate, and phenylacetonitrile. However, HO headspace composition was significantly different in comparison to NE and HoS with respect to phenylacetaldehyde and linalool derivatives abundance that appeared as the consequence of the hive conditions and the bee enzyme activity. C. unshiu honey traceability is determined by chemical markers: phenylacetaldehyde, phenylacetonitrile, linalool and its derivatives, as well as 1H-indole, 1,3-dihydro-2H-indol-2-one, and caffeine. PMID- 27689987 TI - Mining Chromatographic Enantioseparation Data Using Matched Molecular Pair Analysis. AB - We apply matched molecular pair (MMP) analysis to data from ChirBase, which contains literature reports of chromatographic enantioseparations. For the 19 chiral stationary phases we examined, we were able to identify 289 sets of pairs where there is a statistically significant and consistent difference in enantioseparation due to a small chemical change. In many cases these changes highlight enantioselectivity differences between pairs or small families of closely related molecules that have for many years been used to probe the mechanisms of chromatographic chiral recognition; for example, the comparison of N-H vs. N-Me analytes to determine the criticality of an N-H hydrogen bond in chiral molecular recognition. In other cases, statistically significant MMPs surfaced by the analysis are less familiar or somewhat puzzling, sparking a need to generate and test hypotheses to more fully understand. Consequently, mining of appropriate datasets using MMP analysis provides an important new approach for studying and understanding the process of chromatographic enantioseparation. PMID- 27689988 TI - Increasing the Level of IRS-1 and Insulin Pathway Sensitivity by Natural Product Carainterol A. AB - Carainterol A is a eudesmane sesquiterpenoid extracted from Caragana intermedia. We have reported that carainterol A showed potent glucose consumption activity in C2C12 muscle cells and the db/db mouse model. However, the mechanism of the hypoglycemic effect of carainterol A remains elusive. In this article, we present a network pharmacology approach to predict the target and signaling pathway of carainterol A which was subsequently validated in HepG2 cells. It was demonstrated that carainterol A could increase the protein levels of IRS-1 and the downstream protein kinase AKT phosphorylation at a low micromolar level. These findings suggest that carainterol A can be a valuable lead compound and a promising chemical probe for the insulin signaling pathway. PMID- 27689989 TI - Chlorella sorokiniana Extract Improves Short-Term Memory in Rats. AB - Increasing evidence shows that eukaryotic microalgae and, in particular, the green microalga Chlorella, can be used as natural sources to obtain a whole variety of compounds, such as omega (omega)-3 and omega-6 polyunsatured fatty acids (PUFAs). Although either beneficial or toxic effects of Chlorella sorokiniana have been mainly attributed to its specific omega-3 and omega-6 PUFAs content, the underlying molecular pathways remain to be elucidated yet. Here, we investigate the effects of an acute oral administration of a lipid extract of Chlorella sorokiniana, containing mainly omega-3 and omega-6 PUFAs, on cognitive, emotional and social behaviour in rats, analysing possible underlying neurochemical alterations. Our results showed improved short-term memory in Chlorella sorokiniana-treated rats compared to controls, without any differences in exploratory performance, locomotor activity, anxiety profile and depressive like behaviour. On the other hand, while the social behaviour of Chlorella sorokiniana-treated animals was significantly decreased, no effects on aggressivity were observed. Neurochemical investigations showed region-specific effects, consisting in an elevation of noradrenaline (NA) and serotonin (5-HT) content in hippocampus, but not in the prefrontal cortex and striatum. In conclusion, our results point towards a beneficial effect of Chlorella sorokiniana extract on short-term memory, but also highlight the need of caution in the use of this natural supplement due to its possible masked toxic effects. PMID- 27689990 TI - Homeodomain-Interacting Protein Kinase-2: A Critical Regulator of the DNA Damage Response and the Epigenome. AB - Homeodomain-interacting protein kinase 2 (HIPK2) is a serine/threonine kinase that phosphorylates and activates the apoptotic program through interaction with diverse downstream targets including tumor suppressor p53. HIPK2 is activated by genotoxic stimuli and modulates cell fate following DNA damage. The DNA damage response (DDR) is triggered by DNA lesions or chromatin alterations. The DDR regulates DNA repair, cell cycle checkpoint activation, and apoptosis to restore genome integrity and cellular homeostasis. Maintenance of the DDR is essential to prevent development of diseases caused by genomic instability, including cancer, defects of development, and neurodegenerative disorders. Recent studies reveal a novel HIPK2-mediated pathway for DDR through interaction with chromatin remodeling factor homeodomain protein 1gamma. In this review, we will highlight the molecular mechanisms of HIPK2 and show its functions as a crucial DDR regulator. PMID- 27689991 TI - MicroRNA-375 Functions as a Tumor-Suppressor Gene in Gastric Cancer by Targeting Recepteur d'Origine Nantais. AB - Emerging evidence supports a fundamental role for microRNAs (miRNA) in regulating cancer metastasis. Recently, microRNA-375 (miR-375) was reported to be downregulated in many types of cancers, including gastric cancer. Increase in the expression of Recepteur d'Origine Nantais (RON), a receptor tyrosine kinase, has been reported in tumors. However, the function of miR-375 and RON expression in gastric cancer metastasis has not been sufficiently studied. In silico analysis identified miR-375 binding sites in the 3'-untranslated regions (3'-UTR) of the RON-encoding gene. Expression of miR-375 resulted in reduced activity of a luciferase reporter containing the 3'-UTR fragments of RON-encoding mRNA, confirming that miR-375 directly targets the 3'-UTR of RON mRNA. Moreover, we found that overexpression of miR-375 inhibited mRNA and protein expression of RON, which was accompanied by the suppression of cell proliferation, migration, and invasion in gastric cancer AGS and MKN-28 cells. Ectopic miR-375 expression also induced G1 cell cycle arrest through a decrease in the expression of cyclin D1, cyclin D3, and in the phosphorylation of retinoblastoma (Rb). Knockdown of RON by RNAi, similar to miR-375 overexpression, suppressed tumorigenic properties and induced G1 arrest through a decrease in the expression of cyclin D1, cyclin D3, and in the phosphorylation of Rb. Thus, our study provides evidence that miR 375 acts as a suppressor of metastasis in gastric cancer by targeting RON, and might represent a new potential therapeutic target for gastric cancer. PMID- 27689992 TI - Urine Levels of Defensin alpha1 Reflect Kidney Injury in Leptospirosis Patients. AB - Leptospirosis is a zoonotic disease whose severe forms are often accompanied by kidney dysfunction. In the present study, urinary markers were studied for potential prediction of disease severity. Urine samples from 135 patients with or without leptospirosis at San Lazaro Hospital, the Philippines, were analyzed. Urine levels of defensin alpha1 (uDA1) were compared with those of neutrophil gelatinase-associated lipocalin (uNGAL) and N-acetyl-beta-d-glucosidase (uNAG). Serum creatinine (Cr) was used as a marker of kidney injury. The levels of uDA1/Cr, uNGAL/Cr, and uNAG/Cr were positive in 46%, 90%, and 80% of leptospirosis patients, and 69%, 70%, and 70% of non-leptospirosis patients, respectively. In leptospirosis patients, the correlation of uDA1/Cr, uNGAL/Cr and uNAG/Cr levels with serum Cr were r = 0.3 (p < 0.01), r = 0.29 (p < 0.01), and r = 0.02 (p = 0.81), respectively. uDA1/Cr levels were correlated with uNGAL/Cr levels (r = 0.49, p < 0.01) and uNAG/Cr levels (r = 0.47, p < 0.0001) in leptospirosis patients. These findings suggest that uDA1, uNGAL, and uNAG were elevated in leptospirosis patients and reflected various types of kidney damage. uDA1 and uNGAL can be used to track kidney injury in leptospirosis patients because of their correlation with the serum Cr level. PMID- 27689993 TI - Elevated Expression of Calpain-4 Predicts Poor Prognosis in Patients with Gastric Cancer after Gastrectomy. AB - Calpain-4 belongs to the calpain family of calcium-dependent cysteine proteases, and functions as a small regulatory subunit of the calpains. Recent evidence indicates that calpain-4 plays critical roles in tumor migration and invasion. However, the roles of calpain-4 in gastric tumorigenesis remain poorly understood. Herein, we examined calpain-4 expression by immunohistochemical staining on tissue microarrays containing tumor samples of 174 gastric cancer patients between 2004 and 2008 at a single center. The Kaplan-Meier method was used to compare survival curves, and expression levels were correlated to clinicopathological factors and overall survival. Our data demonstrated that calpain-4 was generally increased in gastric cancer cell lines and primary tumor tissues. High expression of calpain-4 was positively associated with vessel invasion, lymph node metastasis, and advanced TNM (Tumor Node Metastasis) stage. Multivariate analysis identified calpain-4 as an independent prognostic factor for poor prognosis. A predictive nomogram integrating calpain-4 expression with other independent prognosticators was constructed, which generated a better prognostic value for overall survival of gastric cancer patients than a TNM staging system. In conclusion, calpain-4 could be regarded as a potential prognosis indicator for clinical outcomes in gastric cancer. PMID- 27689994 TI - Selenomethionine Ameliorates Neuropathology in the Olfactory Bulb of a Triple Transgenic Mouse Model of Alzheimer's Disease. AB - Olfactory dysfunction is an early and common symptom in Alzheimer's disease (AD) and is reported to be related to several pathologic changes, including the deposition of Abeta and hyperphosphorylated tau protein as well as synaptic impairment. Selenomethionine (Se-Met), the major form of selenium in animals and humans, may be a promising therapeutic option for AD as it decreases the deposition of Abeta and tau hyperphosphorylation in a triple transgenic mouse model of AD (3* Tg-AD). In this study, 4-month-old AD mice were treated with 6 ug/mL Se-Met in drinking water for 12 weeks and the effect of Se-Met on neuropathological deficits in olfactory bulb (OB) of 3* Tg-AD mice was investigated. The administration of Se-Met effectively decreased the production and deposition of Abeta by inhibiting beta-site amyloid precursor protein cleaving enzyme 1 (BACE1)-regulated amyloid precursor protein (APP) processing and reduced the level of total tau and phosphorylated tau, which depended on depressing the activity and expression of glycogen synthase kinase-3beta (GSK 3beta) and cyclin-dependent kinase 5 (CDK5). Meanwhile, Se-Met reduced glial activation, relieved neuroinflammation and attenuated neuronal cell death in the OB of AD mice. So Se-Met could improve pathologic changes of AD in the OB, which further demonstrated the potential therapeutic effect of Se-Met in AD. PMID- 27689995 TI - Probiotics Differently Affect Gut-Associated Lymphoid Tissue Indolamine-2,3 Dioxygenase mRNA and Cerebrospinal Fluid Neopterin Levels in Antiretroviral Treated HIV-1 Infected Patients: A Pilot Study. AB - Recently the tryptophan pathway has been considered an important determinant of HIV-1 infected patients' quality of life, due to the toxic effects of its metabolites on the central nervous system (CNS). Since the dysbiosis described in HIV-1 patients might be responsible for the microbial translocation, the chronic immune activation, and the altered utilization of tryptophan observed in these individuals, we speculated a correlation between high levels of immune activation markers in the cerebrospinal fluid (CSF) of HIV-1 infected patients and the over expression of indolamine-2,3-dioxygenase (IDO) at the gut mucosal surface. In order to evaluate this issue, we measured the levels of neopterin in CSF, and the expression of IDO mRNA in gut-associated lymphoid tissue (GALT), in HIV-1 infected patients on effective combined antiretroviral therapy (cART), at baseline and after six months of probiotic dietary management. We found a significant reduction of neopterin and IDO mRNA levels after the supplementation with probiotic. Since the results for the use of adjunctive therapies to reduce the levels of immune activation markers in CSF have been disappointing so far, our pilot study showing the efficacy of this specific probiotic product should be followed by a larger confirmatory trial. PMID- 27689997 TI - Preparation, Characterization and in Vivo Antimycobacterial Studies of Panchovillin-Chitosan Nanocomposites. AB - Chitosan (CS, molecular weight 20.2 kDa, degree of deacylation (DD) 73.31%) was successfully obtained by deacetylation of chitin extracted from shrimp (Litopenaeus vannamei) shell wastes. The encapsulation of the bioactive natural product, panchovillin (PANV), isolated from Erythrina schliebenii, on a chitosan tripolyphosphate (CS/TPP) nano-framework was achieved by ionotropic gelation. Characterization of pure CS, CS/TPP and PANV-CS/TPP nanocomposites was performed by FTIR, SEM and XRD. The molecular weight of chitosan and the thermal stability of the materials were determined by MALDI-TOF-MS and simultaneous thermal analyzer (STA)/DTG, respectively. The respective encapsulation efficiency and loading capacity of the PANV were found to be 70% and 0.36%. The in vitro release studies showed an initial burst of 42% of PANV in the first six hours. This was followed by a slow and sustained release up to 72 h. The in vivo antimycobacterial activities of both PANV and PANV-CS/TPP nanocomposite against Mycobacterium indicus pranii (MIP) using Galleria mellonella larvae as an in vivo infection model are reported in this paper. PMID- 27689996 TI - An Inflammatory Nucleus Pulposus Tissue Culture Model to Test Molecular Regenerative Therapies: Validation with Epigallocatechin 3-Gallate. AB - Organ cultures are practical tools to investigate regenerative strategies for the intervertebral disc. However, most existing organ culture systems induce severe tissue degradation with only limited representation of the in vivo processes. The objective of this study was to develop a space- and cost-efficient tissue culture model, which represents degenerative processes of the nucleus pulposus (NP). Intact bovine NPs were cultured in a previously developed system using Dyneema jackets. Degenerative changes in the NP tissue were induced either by the direct injection of chondroitinase ABC (1-20 U/mL) or by the diffusion of interleukin-1 beta (IL-1beta) and tumor necrosis factor alpha (TNF-alpha) (both 100 ng/mL) from the culture media. Extracellular matrix composition (collagens, proteoglycans, water, and DNA) and the expression of inflammatory and catabolic genes were analyzed. The anti-inflammatory and anti-catabolic compound epigallocatechin 3 gallate (EGCG, 10 uM) was employed to assess the relevance of the degenerative NP model. Although a single injection of chondroitinase ABC reduced the proteoglycan content in the NPs, it did not activate cellular responses. On the other hand, IL 1beta and TNF-alpha significantly increased the mRNA expression of inflammatory mediators IL-6, IL-8, inducible nitric oxide synthase (iNOS), prostaglandin endoperoxide synthase 2 (PTGS2) and matrix metalloproteinases (MMP1, MMP3, and MMP13). The cytokine-induced gene expression in the NPs was ameliorated with EGCG. This study provides a proof of concept that inflammatory NP cultures, with appropriate containment, can be useful for the discovery and evaluation of molecular therapeutic strategies against early degenerative disc disease. PMID- 27689998 TI - Isobaric Tags for Relative and Absolute Quantitation (iTRAQ)-Based Comparative Proteome Analysis of the Response of Ramie under Drought Stress. AB - In this study, we conducted the first isobaric tags for relative and absolute quantitation (isobaric tags for relative and absolute quantitation (iTRAQ))-based comparative proteomic analysis of ramie plantlets after 0 (minor drought stress), 24 (moderate drought stress), and 72 h (severe drought stress) of treatment with 15% (w/v) poly (ethylene glycol)6000 (PEG6000) to simulate drought stress. In our study, the association analysis of proteins and transcript expression revealed 1244 and 968 associated proteins identified in leaves and roots, respectively. L1, L2, and L3 are leaf samples which were harvested at 0, 24, and 72 h after being treated with 15% PEG6000, respectively. Among those treatment groups, a total of 118, 216, and 433 unique proteins were identified as differentially expressed during L1 vs. L2, L2 vs. L3, and L1 vs. L3, respectively. R1, R2, and R3 are root samples which were harvested at 0, 24, and 72 h after being treated with 15% PEG6000, respectively. Among those treatment groups,a total of 124, 27, and 240 unique proteins were identified as differentially expressed during R1 vs. R2, R2 vs. R3, and R1 vs. R3, respectively. Bioinformatics analysis indicated that glycolysis/gluconeogenesis was significantly upregulated in roots in response to drought stress. This enhancement may result in more glycolytically generated adenosine triphosphate (ATP) in roots to adapt to adverse environmental conditions. To obtain complementary information related to iTRAQ data, the mRNA levels of 12 proteins related to glycolysis/gluconeogenesis in leaves and 7 in roots were further analyzed by qPCR. Most of their expression levels were higher in R3 than R1 and R2, suggesting that these compounds may promote drought tolerance by modulating the production of available energy. PMID- 27689999 TI - CAPS1 Negatively Regulates Hepatocellular Carcinoma Development through Alteration of Exocytosis-Associated Tumor Microenvironment. AB - The calcium-dependent activator protein for secretion 1 (CAPS1) regulates exocytosis of dense-core vesicles (DCVs) in neurons and neuroendocrine cells. The role of CAPS1 in cancer biology remains unknown. The purpose of this study was to investigate the role of CAPS1 in hepatocellular carcinoma (HCC). We determined the levels of CAPS1 in eight hepatoma cell lines and 141 HCC specimens. We evaluated the prognostic value of CAPS1 expression and its association with clinical parameters. We investigated the biological consequences of CAPS1 overexpression in two hepatoma cell lines in vitro and in vivo. The results showed that loss of CAPS1 expression in HCC tissues was markedly correlated with aggressive tumor phenotypes, such as high-grade tumor node metastasis (TNM) stage (p = 0.003) and absence of tumor encapsulation (p = 0.016), and was associated with poor overall survival (p = 0.008) and high recurrence (p = 0.015). CAPS1 overexpression inhibited cell proliferation and migration by changing the exocytosis-associated tumor microenvironment in hepatoma cells in vitro. The in vivo study showed that CAPS1 overexpression inhibited xenograft tumor growth. Together, these results identified a previously unrecognized tumor suppressor role for CAPS1 in HCC development. PMID- 27690000 TI - Ocular Albinism Type 1 Regulates Melanogenesis in Mouse Melanocytes. AB - To investigate whether ocular albinism type 1 (OA1) is differentially expressed in the skin of mice with different coat colors and to determine its correlation with coat color establishment in mouse, the expression patterns and tissue distribution characterization of OA1 in the skin of mice with different coat colors were qualitatively and quantitatively analyzed by real-time quantitative PCR (qRT-PCR), immunofluorescence staining and Western blot. The qRT-PCR analysis revealed that OA1 mRNA was expressed in all mice skin samples tested, with the highest expression level in brown skin, a moderate expression level in black skin and the lowest expression level in gray skin. Positive OA1 protein bands were also detected in all skin samples by Western blot analysis. The relative expression levels of OA1 protein in both black and brown skin were significantly higher than that in gray skin, but there was no significant difference between black and brown mice. Immunofluorescence assays revealed that OA1 was mainly expressed in the hair follicle matrix, the inner and outer root sheath in the skin tissues with different coat colors. To get further insight into the important role of OA1 in the melanocytes' pigmentation, we transfected the OA1 into mouse melanocytes and then detected the relative expression levels of pigmentation-related gene. Simultaneously, we tested the melanin content of melanocytes. As a result, the overexpression of OA1 significantly increased the expression levels of microphthalmia-associated transcription factor (MITF), tyrosinase (TYR), tyrosinase-related protein 1 (TRP1) and premelanosome protein (PMEL). However, the tyrosinase-related protein 2 (TRP2) level was attenuated. By contrast, the level of glycoprotein non-metastatic melanoma protein b (GPNMB) was unaffected by OA1 overexpression. Furthermore, we observed a significant increase in melanin content in mouse melanocyte transfected OA1. Therefore, we propose that OA1 may participate in the formation of coat color by regulating the level of MITF and the number, size, motility and maturation of melanosome. PMID- 27690001 TI - Sodium Copper Chlorophyllin Immobilization onto Hippospongia communis Marine Demosponge Skeleton and Its Antibacterial Activity. AB - In this study, Hippospongia communis marine demosponge skeleton was used as an adsorbent for sodium copper chlorophyllin (SCC). Obtained results indicate the high sorption capacity of this biomaterial with respect to SCC. Batch experiments were performed under different conditions and kinetic and isotherms properties were investigated. Acidic pH and the addition of sodium chloride increased SCC adsorption. The experimental data were well described by a pseudo-second order kinetic model. Equilibrium adsorption isotherms were determined and the experimental data were analyzed using both Langmuir and Freundlich isotherms. The effectiveness of the process was confirmed by 13C Cross Polarization Magic Angle Spinning Nuclear Magnetic Resonance (13C CP/MAS NMR), Fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDS) and thermogravimetric analysis (TG). This novel SCC-sponge-based functional hybrid material was found to exhibit antimicrobial activity against the gram-positive bacterium Staphylococcus aureus.

AB - BACKGROUND: An association between the level of vitamin D and the risk of pregnancy-related complications remains unclear. The aim of this study was to examine concentrations of 25(OH) vitamin D in Polish women with normal pregnancies and pregnancies complicated by gestational hypertension, preeclampsia or gestational diabetes mellitus (GDM). Moreover, we analyzed an association between maternal serum 25(OH)D and the risk of gestational hypertension, preeclampsia and GDM. MATERIAL AND METHODS: The study included 207 pregnant women, among them 171 with pregnancy-related complications: gestational hypertension (n = 45), preeclampsia (n = 23) or GDM (n = 103). The control group consisted of 36 women with normal pregnancies. Concentrations of serum 25(OH)D were measured at admission to the hospital prior to delivery Results: Patients with hypertension did not differ significantly from the controls in terms of their serum 25(OH)D concentrations (18.20 vs. 22.10 ng/mL, p = 0.15). Highly significant differences were found in 25(OH)D concentrations of women with preeclampsia and the controls (14.75 vs. 22.10 ng/mL, p = 0.0021). GDM was not associated with significant differences in 25(OH)D concentration. A low level of 25(OH)D turned out to be associated with an increased risk of preeclampsia during pregnancy on both univariate and multivariate regression analysis, and was a significant predictor of this condition on ROC (receiver operating characteristic) analysis (AUC = 0.70, p < 0.01). CONCLUSIONS: 25(OH)D deficiency is common among pregnant Polish women. Low concentrations of 25(OH)D may play a role in the etiopathogenesis of preeclampsia. Routine assessment of the 25(OH)D level during pregnancy may be crucial for the identification of women at increased risk of preeclampsia.

AB - Serine and arginine rich splicing factor 2(SRSF2) belongs to the serine/arginine (SR)-rich family of proteins that regulate alternative splicing. Previous studies suggested that SRSF2 can contribute to carcinogenic processes. Clear cell renal cell carcinoma (ccRCC) is the most common subtype of kidney cancer, highly aggressive and difficult to treat, mainly due to resistance to apoptosis. In this study we hypothesized that SRSF2 contributes to the regulation of apoptosis in ccRCC. Using tissue samples obtained from ccRCC patients, as well as independent validation on The Cancer Genome Atlas (TCGA) data, we demonstrate for the first time that expression of SRSF2 is decreased in ccRCC tumours when compared to non tumorous control tissues. Furthermore, by employing a panel of ccRCC-derived cell lines with silenced SRSF2 expression and qPCR arrays we show that SRSF2 contributes not only to splicing patterns but also to expression of multiple apoptotic genes, including new SRSF2 targets: DIABLO, BIRC5/survivin, TRAIL, BIM, MCL1, TNFRSF9, TNFRSF1B, CRADD, BCL2L2, BCL2A1, and TP53. We also identified a new splice variant of CFLAR, an inhibitor of caspase activity. These changes culminate in diminished caspase-9 activity and inhibition of apoptosis. In summary, we show for the first time that decreased expression of SRSF2 in ccRCC contributes to protection of cancer cells viability. PMID- 27690004 TI - Proteomic Analysis of Hylocereus polyrhizus Reveals Metabolic Pathway Changes. AB - Red dragon fruit or red pitaya (Hylocereus polyrhizus) is the only edible fruit that contains betalains. The color of betalains ranges from red and violet to yellow in plants. Betalains may also serve as an important component of health promoting and disease-preventing functional food. Currently, the biosynthetic and regulatory pathways for betalain production remain to be fully deciphered. In this study, isobaric tags for relative and absolute quantitation (iTRAQ)-based proteomic analyses were used to reveal the molecular mechanism of betalain biosynthesis in H. polyrhizus fruits at white and red pulp stages, respectively. A total of 1946 proteins were identified as the differentially expressed between the two samples, and 936 of them were significantly highly expressed at the red pulp stage of H. polyrhizus. RNA-seq and iTRAQ analyses showed that some transcripts and proteins were positively correlated; they belonged to "phenylpropanoid biosynthesis", "tyrosine metabolism", "flavonoid biosynthesis", "ascorbate and aldarate metabolism", "betalains biosynthesis" and "anthocyanin biosynthesis". In betalains biosynthesis pathway, several proteins/enzymes such as polyphenol oxidase, CYP76AD3 and 4,5-dihydroxy-phenylalanine (DOPA) dioxygenase extradiol-like protein were identified. The present study provides a new insight into the molecular mechanism of the betalain biosynthesis at the posttranscriptional level. PMID- 27690005 TI - Oral Supplementation with a Special Additive of Retinyl Palmitate and Alpha Tocopherol Reduces Growth Retardation in Young Pancreatic Duct Ligated Pigs Used as a Model for Children Suffering from Exocrine Pancreatic Insufficiency. AB - Pancreatic exocrine insufficiency (PEI) is a disease of diverse aetiology-e.g., majority of patients suffering from cystic fibrosis (CF) show PEI congenitally. Malnutrition and malabsorption of nutrients impair growth and nutritional status. As reduced fat digestion leads to a deficiency of fat-soluble vitamins the supplementation is standard, but absorption is a critical point in PEI-patients. The pancreatic duct ligated (PL) pig is an established model for PEI in humans and has been proven to be a suitable model to compare different vitamin additives for supplementation. In a former study, PEI caused distinct growth retardation in young piglets, but did not affect growth in older ones. Our study hypothesised that this age-dependent effect is caused by exhausted body reserves of fat soluble vitamins and, therefore, extra supply reduces growth retardation. PEI was induced by PL at the age of seven (PL-7) or 16 weeks (PL-16). Controls (C) underwent a sham surgery. Some PL-7 pigs (PL-7 + Vit) were fed a special vitamin additive. PEI reduced the mean final body weight (kg) at 26 weeks of age significantly with lower effect in PL-16-pigs (C:117; PL-7:49.5; PL-7 + Vit:77.1; PL-16:96.4). Extra vitamin supply resulted in an increased growth and normalised serum concentration of alpha-tocopherol, underlining the importance of special supplementation in PEI-patients. PMID- 27690006 TI - iTRAQ-Based Proteomics Analysis of Serum Proteins in Wistar Rats Treated with Sodium Fluoride: Insight into the Potential Mechanism and Candidate Biomarkers of Fluorosis. AB - Fluorosis induced by exposure to high level fluoride is quite widespread in the world. The manifestations of fluorosis include dental mottling, bone damage, and impaired malfunction of soft tissues. However, the molecular mechanism of fluorosis has not been clarified until now. To explore the underlying mechanisms of fluorosis and screen out serum biomarkers, we carried out a quantitative proteomics study to identify differentially expressed serum proteins in Wistar rats treated with sodium fluoride (NaF) by using a proteomics approach of isobaric tagging for relative and absolute quantitation (iTRAQ). We fed Wistar rats drinking water that had 50, 150, and 250 mg/L of dissolved NaF for 24 weeks. For the experimental duration, each rat was given an examination of the lower incisors to check for the condition of dental fluorosis (DF). By the end of the treatment, fluoride ion concentration in serum and lower incisors were detected. The results showed that NaF treatment can induce rat fluorosis. By iTRAQ analysis, a total of 37 differentially expressed serum proteins were identified between NaF-treated and control rats. These proteins were further analyzed by bioinformatics, out of which two proteins were validated by enzyme-linked immunoadsorbent assays (ELISA). The major proteins were involved in complement and coagulation cascade, inflammatory response, complement activation, defense response, and wound response, suggesting that inflammation and immune reactions may play a key role in fluorosis pathogenesis. These proteins may contribute to the understanding of the mechanism of fluoride toxicity, and may serve as potential biomarkers for fluorosis. PMID- 27690007 TI - Stereoselective Blockage of Quinidine and Quinine in the hERG Channel and the Effect of Their Rescue Potency on Drug-Induced hERG Trafficking Defect. AB - Diastereoisomers of quinidine and quinine are used to treat arrhythmia and malaria, respectively. It has been reported that both drugs block the hERG (human ether-a-go-go-related gene) potassium channel which is essential for myocardium repolarization. Abnormality of repolarization increases risk of arrhythmia. The aim of our research is to study and compare the impacts of quinidine and quinine on hERG. Results show that both drugs block the hERG channel, with quinine 14 fold less potent than quinidine. In addition, they presented distinct impacts on channel dynamics. The results imply their stereospecific block effect on the hERG channel. However, F656C-hERG reversed this stereoselectivity. The mutation decreases affinity of the two drugs with hERG, and quinine was more potent than quinidine in F656C-hERG blockage. These data suggest that F656 residue contributes to the stereoselective pocket for quinidine and quinine. Further study demonstrates that both drugs do not change hERG protein levels. In rescue experiments, we found that they exert no reverse effect on pentamidine- or desipramine-induced hERG trafficking defect, although quinidine has been reported to rescue trafficking-deficient pore mutation hERG G601S based on the interaction with F656. Our research demonstrated stereoselective effects of quinidine and quinine on the hERG channel, and this is the first study to explore their reversal potency on drug-induced hERG deficiency. PMID- 27690008 TI - Diatom Valve Three-Dimensional Representation: A New Imaging Method Based on Combined Microscopies. AB - The frustule of diatoms, unicellular microalgae, shows very interesting photonic features, generally related to its complicated and quasi-periodic micro- and nano structure. In order to simulate light propagation inside and through this natural structure, it is important to develop three-dimensional (3D) models for synthetic replica with high spatial resolution. In this paper, we present a new method that generates images of microscopic diatoms with high definition, by merging scanning electron microscopy and digital holography microscopy or atomic force microscopy data. Starting from two digital images, both acquired separately with standard characterization procedures, a high spatial resolution (Deltaz = lambda/20, Deltax = Deltay ? 100 nm, at least) 3D model of the object has been generated. Then, the two sets of data have been processed by matrix formalism, using an original mathematical algorithm implemented on a commercially available software. The developed methodology could be also of broad interest in the design and fabrication of micro-opto-electro-mechanical systems. PMID- 27690009 TI - CXCL12/CXCR4 Axis Regulates Aggrecanase Activation and Cartilage Degradation in a Post-Traumatic Osteoarthritis Rat Model. AB - We evaluated the role of the CXCL12/CXCR4 (C-X-C motif chemokine ligand 12/C-X-C chemokine receptor type 4) axis in aggrecanase-mediated cartilage degradation, and explored the underlying mechanism in a post-traumatic osteoarthritis rat model. Expression of CXCL12/CXCR4 and ADAMTS-5 was analyzed in the knees of osteoarthritic and non-arthritic rats using Western blot, ELISA, immunohistochemistry and immunofluorescence. Rodent studies were performed using Sprague-Dawley rats, with animals divided into three groups: Destabilization of the medial meniscus/AMD3100-treated (DMM/AMD3100-treated), DMM/PBS-treated, and sham controls. Rats were sacrificed after eight weeks, and samples were collected for histology and immunohistochemistry analyses. IL-1-pretreated primary chondrocytes were cultured with untreated control, CXCL12a, siNC + CXCL12a, or siRNA CXCR4 + CXCL12a, and analyzed for expression of relevant markers and cellular pathways. Higher levels of CXCL12 were detected in the knee fluid of osteoarthritic subjects, with strong staining for CXCR4 in chondrocytes and CXCL12 in synoviocytes together with enhanced expression of ADAMTS-5. DMM/AMD3100 treated rats showed a significantly reduced immunological response, with minimal evidence of pathology in both histological and immunohistochemical analyses. Treatment with CXCL12a increased the expression of ACAN, RUNX-2, and ADAMTS-4/5 in IL-1-pretreated primary chondrocytes, together with a decrease in the expression of SOX-9. Molecular analyses revealed strong induction of NF-kappaB activation, along with phosphorylation of MAPKs, and activation of canonical Wnt/beta-catenin signaling. In conclusion, inhibition of SDF-1alpha/CXCR4 signaling axis was able to inhibit aggrecanase expression and lessen cartilage degeneration in post-traumatic osteoarthritis rats. PMID- 27690010 TI - Recent Advances in Understanding Amino Acid Sensing Mechanisms that Regulate mTORC1. AB - The mammalian target of rapamycin (mTOR) is the central regulator of mammalian cell growth, and is essential for the formation of two structurally and functionally distinct complexes: mTORC1 and mTORC2. mTORC1 can sense multiple cues such as nutrients, energy status, growth factors and hormones to control cell growth and proliferation, angiogenesis, autophagy, and metabolism. As one of the key environmental stimuli, amino acids (AAs), especially leucine, glutamine and arginine, play a crucial role in mTORC1 activation, but where and how AAs are sensed and signal to mTORC1 are not fully understood. Classically, AAs activate mTORC1 by Rag GTPases which recruit mTORC1 to lysosomes, where AA signaling initiates. Plasma membrane transceptor L amino acid transporter 1 (LAT1)-4F2hc has dual transporter-receptor function that can sense extracellular AA availability upstream of mTORC1. The lysosomal AA sensors (PAT1 and SLC38A9) and cytoplasmic AA sensors (LRS, Sestrin2 and CASTOR1) also participate in regulating mTORC1 activation. Importantly, AAs can be sensed by plasma membrane receptors, like G protein-coupled receptor (GPCR) T1R1/T1R3, and regulate mTORC1 without being transported into the cells. Furthermore, AA-dependent mTORC1 activation also initiates within Golgi, which is regulated by Golgi-localized AA transporter PAT4. This review provides an overview of the research progress of the AA sensing mechanisms that regulate mTORC1 activity. PMID- 27690012 TI - EpCAM Expression in Lymph Node and Bone Metastases of Prostate Carcinoma: A Pilot Study. AB - There is an urgent need for new imaging modalities in prostate carcinoma staging. A non-invasive modality that can assess lymph node and bone metastases simultaneously is preferred. Epithelial cell adhesion molecule (EpCAM) is a membranous protein of interest as an imaging target since it is overexpressed in prostatic carcinoma compared with benign prostate epithelium and compared with stroma. However, EpCAM expression in lymph node metastases is sparsely available in the literature and EpCAM expression in bone metastases is yet unknown. The current study evaluates the expression of EpCAM in prostate carcinoma lymph nodes, in matched normal lymph nodes, in prostate carcinoma bone metastases, and in normal bone by immunohistochemistry. EpCAM was expressed in 100% of lymph node metastases (21 out of 21), in 0% of normal lymph nodes (0 out of 21), in 95% of bone metastases (19 out of 20), and in 0% of normal bone (0 out of 14). Based on these results, EpCAM may be a feasible imaging target in prostate carcinoma lymph node and bone metastases. Prospective clinical trials are needed to confirm current results. Preoperative visualization of prostate carcinoma metastases will improve disease staging and will prevent unnecessary invasive surgery. PMID- 27690011 TI - Aquaporin-4: A Potential Therapeutic Target for Cerebral Edema. AB - Aquaporin-4 (AQP4) is a family member of water-channel proteins and is dominantly expressed in the foot process of glial cells surrounding capillaries. The predominant expression at the boundaries between cerebral parenchyma and major fluid compartments suggests the function of aquaporin-4 in water transfer into and out of the brain parenchyma. Accumulating evidences have suggested that the dysregulation of aquaporin-4 relates to the brain edema resulting from a variety of neuro-disorders, such as ischemic or hemorrhagic stroke, trauma, etc. During edema formation in the brain, aquaporin-4 has been shown to contribute to the astrocytic swelling, while in the resolution phase, it has been seen to facilitate the reabsorption of extracellular fluid. In addition, aquaporin-4 deficient mice are protected from cytotoxic edema produced by water intoxication and brain ischemia. However, aquaporin-4 deletion exacerbates vasogenic edema in the brain of different pathological disorders. Recently, our published data showed that the upregulation of aquaporin-4 in astrocytes probably contributes to the transition from cytotoxic edema to vasogenic edema. In this review, apart from the traditional knowledge, we also introduce our latest findings about the effects of mesenchymal stem cells (MSCs) and microRNA-29b on aquaporin-4, which could provide powerful intervention tools targeting aquaporin-4. PMID- 27690013 TI - Time in Redox Adaptation Processes: From Evolution to Hormesis. AB - Life on Earth has to adapt to the ever changing environment. For example, due to introduction of oxygen in the atmosphere, an antioxidant network evolved to cope with the exposure to oxygen. The adaptive mechanisms of the antioxidant network, specifically the glutathione (GSH) system, are reviewed with a special focus on the time. The quickest adaptive response to oxidative stress is direct enzyme modification, increasing the GSH levels or activating the GSH-dependent protective enzymes. After several hours, a hormetic response is seen at the transcriptional level by up-regulating Nrf2-mediated expression of enzymes involved in GSH synthesis. In the long run, adaptations occur at the epigenetic and genomic level; for example, the ability to synthesize GSH by phototrophic bacteria. Apparently, in an adaptive hormetic response not only the dose or the compound, but also time, should be considered. This is essential for targeted interventions aimed to prevent diseases by successfully coping with changes in the environment e.g., oxidative stress. PMID- 27690015 TI - GSPE Inhibits HMGB1 Release, Attenuating Renal IR-Induced Acute Renal Injury and Chronic Renal Fibrosis. AB - Grape seed proanthocyanindin extract (GSPE) is a polyphenolic bioflavonoid derived from grape seeds and has been widely studied for its potent antioxidant, anti-inflammatory and antitumor activities. HMGB1 is a newly discovered danger associated molecular pattern (DAMP) that has potent proinflammatory effects once released by necrotic cells. However, the effect of GSPE on the HMGB1, and the relationship of those two with acute kidney injury and chronic kidney fibrosis are unknown. This study aimed to investigate the impact of GSPE on acute kidney injury and chronic fibrosis. C57bl/6 mice were subjected to bilateral ischemia/reperfusion (I/R) and unilateral I/R with or without GSPE administration. After bilateral I/R, mice administered GSPE had a marked improvement in renal function (BUN and Cr), decreased pathological damage and reduced inflammation. In unilateral I/R, mice subjected GSPE showed reduced tubulointerstitial fibrosis and decreased inflammatory reaction. The renoprotection of GSPE on both models was associated with the inhibition of HMGB1 nucleocytoplasmic shuttling and release, which can amplify the inflammation through binding to its downstream receptor TLR4 and facilitated P65 transcription. Thus, we have reason to believe that GSPE could be a good alternative therapy for the prevention and treatment of IR-induced renal injury and fibrosis in clinical practice. PMID- 27690017 TI - Extracellular Self-DNA (esDNA), but Not Heterologous Plant or Insect DNA (etDNA), Induces Plasma Membrane Depolarization and Calcium Signaling in Lima Bean (Phaseolus lunatus) and Maize (Zea mays). AB - Extracellular self-DNA (esDNA) is produced during cell and tissue damage or degradation and has been shown to induce significant responses in several organisms, including plants. While the inhibitory effects of esDNA have been shown in conspecific individuals, little is known on the early events involved upon plant esDNA perception. We used electrophysiology and confocal laser scanning microscopy calcium localization to evaluate the plasma membrane potential (Vm) variations and the intracellular calcium fluxes, respectively, in Lima bean (Phaseolus lunatus) and maize (Zea mays) plants exposed to esDNA and extracellular heterologous DNA (etDNA) and to etDNA from Spodoptera littoralis larvae and oral secretions. In both species, esDNA induced a significant Vm depolarization and an increased flux of calcium, whereas etDNA was unable to exert any of these early signaling events. These findings confirm the specificity of esDNA to induce plant cell responses and to trigger early signaling events that eventually lead to plant response to damage. PMID- 27690014 TI - New Treatment Strategies for Alcohol-Induced Heart Damage. AB - High-dose alcohol misuse induces multiple noxious cardiac effects, including myocyte hypertrophy and necrosis, interstitial fibrosis, decreased ventricular contraction and ventricle enlargement. These effects produce diastolic and systolic ventricular dysfunction leading to congestive heart failure, arrhythmias and an increased death rate. There are multiple, dose-dependent, synchronic and synergistic mechanisms of alcohol-induced cardiac damage. Ethanol alters membrane permeability and composition, interferes with receptors and intracellular transients, induces oxidative, metabolic and energy damage, decreases protein synthesis, excitation-contraction coupling and increases cell apoptosis. In addition, ethanol decreases myocyte protective and repair mechanisms and their regeneration. Although there are diverse different strategies to directly target alcohol-induced heart damage, they are partially effective, and can only be used as support medication in a multidisciplinary approach. Alcohol abstinence is the preferred goal, but control drinking is useful in alcohol-addicted subjects not able to abstain. Correction of nutrition, ionic and vitamin deficiencies and control of alcohol-related systemic organ damage are compulsory. Recently, several growth factors (myostatin, IGF-1, leptin, ghrelin, miRNA, and ROCK inhibitors) and new cardiomyokines such as FGF21 have been described to regulate cardiac plasticity and decrease cardiac damage, improving cardiac repair mechanisms, and they are promising agents in this field. New potential therapeutic targets aim to control oxidative damage, myocyte hypertrophy, interstitial fibrosis and persistent apoptosis In addition, stem-cell therapy may improve myocyte regeneration. However, these strategies are not yet approved for clinical use. PMID- 27690016 TI - Phenotype-Genotype Association Analysis of ACTH-Secreting Pituitary Adenoma and Its Molecular Link to Patient Osteoporosis. AB - Adrenocorticotrophin (ACTH)-secreting pituitary adenoma, also known as Cushing disease (CD), is rare and causes metabolic syndrome, cardiovascular disease and osteoporosis due to hypercortisolism. However, the molecular pathogenesis of CD is still unclear because of a lack of human cell lines and animal models. Here, we study 106 clinical characteristics and gene expression changes from 118 patients, the largest cohort of CD in a single-center. RNA deep sequencing is used to examine genotypic changes in nine paired female ACTH-secreting pituitary adenomas and adjacent nontumorous pituitary tissues (ANPT). We develop a novel analysis linking disease clinical characteristics and whole transcriptomic changes, using Pearson Correlation Coefficient to discover a molecular network mechanism. We report that osteoporosis is distinguished from the phenotype and genotype analysis. A cluster of genes involved in osteoporosis is identified using Pearson correlation coefficient analysis. Most of the genes are reported in the bone related literature, confirming the feasibility of phenotype-genotype association analysis, which could be used in the analysis of almost all diseases. Secreted phosphoprotein 1 (SPP1), collagen type I alpha 1 chain (COL1A1), 5' nucleotidase ecto (NT5E), HtrA serine peptidase 1 (HTRA1) and angiopoietin 1 (ANGPT1) and their signalling pathways are shown to be involved in osteoporosis in CD patients. Our discoveries provide a molecular link for osteoporosis in CD patients, and may open new potential avenues for osteoporosis intervention and treatment. PMID- 27690018 TI - Essential Roles of Natural Products and Gaseous Mediators on Neuronal Cell Death or Survival. AB - Although precise cellular and molecular mechanisms underlying neurodegeneration still remain enigmatic, key factors associated with degenerative disorders, such as glutamate toxicity and oxidative stress, have been recently identified. Accordingly, there has been growing interest in examining the effects of exogenous and endogenous molecules on neuroprotection and neurodegeneration. In this paper, we review recent studies on neuroprotective and/or neurodegenerative effects of natural products, such as caffeic acid and chlorogenic acid, and gaseous mediators, including hydrogen sulfide and nitric oxide. Furthermore, possible molecular mechanisms of these molecules in relation to glutamate signals are discussed. Insight into the pathophysiological role of these molecules will make progress in our understanding of molecular mechanisms underlying neurodegenerative diseases, and is expected to lead to potential therapeutic approaches. PMID- 27690019 TI - Longitudinal Claudin Gene Expression Analyses in Canine Mammary Tissues and Thereof Derived Primary Cultures and Cell Lines. AB - Human and canine mammary tumours show partial claudin expression deregulations. Further, claudins have been used for directed therapeutic approaches. However, the development of claudin targeting approaches requires stable claudin expressing cell lines. This study reports the establishment and characterisation of canine mammary tissue derived cell lines, analysing longitudinally the claudin 1, -3, -4 and -7 expressions in original tissue samples, primary cultures and developed cell lines. Primary cultures were derived from 17 canine mammary tissues: healthy, lobular hyperplasia, simple adenoma, complex adenoma, simple tubular carcinoma, complex carcinoma, carcinoma arising in a benign mixed tumour and benign mixed tissue. Cultivation was performed, if possible, until passage 30. Claudin mRNA and protein expressions were analysed by PCR, QuantiGene Plex Assay, immunocytochemistry and immunofluorescence. Further, cytokeratin expression was analysed immunocytochemically. Cultivation resulted in 11 established cell lines, eight showing epithelial character. In five of the early passages the claudin expressions decreased compared to the original tissues. In general, claudin expressions were diminished during cultivation. Three cell lines kept longitudinally claudin, as well as epithelial marker expressions, representing valuable tools for the development of claudin targeted anti-tumour therapies. PMID- 27690020 TI - Fruit Antioxidants during Vinegar Processing: Changes in Content and in Vitro Bio Accessibility. AB - BACKGROUND: Vinegars based on fruit juices could conserve part of the health associated compounds present in the fruits. However, in general very limited knowledge exists on the consequences of vinegar-making on different antioxidant compounds from fruit. In this study vinegars derived from apple and grape are studied. METHODS: A number of steps, starting from the fermentation of the fruit juices to the formation of the final vinegars, were studied from an industrial vinegar process. The effect of each of the vinegar processing steps on content of antioxidants, phenolic compounds and flavonoids was studied, by spectroscopic methods and by high-performance liquid chromatography (HPLC). RESULTS: The major observation was that spectrophotometric methods indicate a strong loss of antioxidant phenolic compounds during the transition from fruit wine to fruit vinegar. A targeted HPLC analysis indicates that metabolites such as gallic acid are lost in later stages of the vinegar process. CONCLUSION: The major conclusion of this work is that major changes occur in phenolic compounds during vinegar making. An untargeted metabolite analysis should be used to reveal these changes in more detail. In addition, the effect of vinegar processing on bio accessibility of phenolic compounds was investigated by mimicking the digestive tract in an in vitro set up. This study is meant to provide insight into the potential of vinegar as a source of health-related compounds from fruit.

AB - Time-resolved step-scan FTIR spectroscopy has been employed to probe the dynamics of the ba3 oxidoreductase from Thermus thermophilus in the ns-MUs time range and in the pH/pD 6-9 range. The data revealed a pH/pD sensitivity of the D372 residue and of the ring-A propionate of heme a3.

PMID- 27690022 TI - Cinnamide Derivatives as Mammalian Arginase Inhibitors: Synthesis, Biological Evaluation and Molecular Docking. AB - Arginases are enzymes that are involved in many human diseases and have been targeted for new treatments. Here a series of cinnamides was designed, synthesized and evaluated in vitro and in silico for their inhibitory activity against mammalian arginase. Using a microassay on purified liver bovine arginase (b-ARG I), (E)-N-(2-phenylethyl)-3,4-dihydroxycinnamide, also named caffeic acid phenylamide (CAPA), was shown to be slightly more active than our natural reference inhibitor, chlorogenic acid (IC50 = 6.9 +/- 1.3 and 10.6 +/- 1.6 uM, respectively) but it remained less active that the synthetic reference inhibitor Nomega-hydroxy-nor-l-arginine nor-NOHA (IC50 = 1.7 +/- 0.2 uM). Enzyme kinetic studies showed that CAPA was a competitive inhibitor of arginase with Ki = 5.5 +/ 1 uM. Whereas the activity of nor-NOHA was retained (IC50 = 5.7 +/- 0.6 uM) using a human recombinant arginase I (h-ARG I), CAPA showed poorer activity (IC50 = 60.3 +/- 7.8 uM). However, our study revealed that the cinnamoyl moiety and catechol function were important for inhibitory activity. Docking results on h ARG I demonstrated that the caffeoyl moiety could penetrate into the active-site pocket of the enzyme, and the catechol function might interact with the cofactor Mn2+ and several crucial amino acid residues involved in the hydrolysis mechanism of arginase. The results of this study suggest that 3,4-dihydroxycinnamides are worth being considered as potential mammalian arginase inhibitors, and could be useful for further research on the development of new arginase inhibitors. PMID- 27690023 TI - Gait Phase Recognition for Lower-Limb Exoskeleton with Only Joint Angular Sensors. AB - Gait phase is widely used for gait trajectory generation, gait control and gait evaluation on lower-limb exoskeletons. So far, a variety of methods have been developed to identify the gait phase for lower-limb exoskeletons. Angular sensors on lower-limb exoskeletons are essential for joint closed-loop controlling; however, other types of sensors, such as plantar pressure, attitude or inertial measurement unit, are not indispensable.Therefore, to make full use of existing sensors, we propose a novel gait phase recognition method for lower-limb exoskeletons using only joint angular sensors. The method consists of two procedures. Firstly, the gait deviation distances during walking are calculated and classified by Fisher's linear discriminant method, and one gait cycle is divided into eight gait phases. The validity of the classification results is also verified based on large gait samples. Secondly, we build a gait phase recognition model based on multilayer perceptron and train it with the phase labeled gait data. The experimental result of cross-validation shows that the model has a 94.45% average correct rate of set (CRS) and an 87.22% average correct rate of phase (CRP) on the testing set, and it can predict the gait phase accurately. The novel method avoids installing additional sensors on the exoskeleton or human body and simplifies the sensory system of the lower-limb exoskeleton. PMID- 27690024 TI - Infrared LED Enhanced Spectroscopic CdZnTe Detector Working under High Fluxes of X-rays. AB - This paper describes an application of infrared light-induced de-polarization applied on a polarized CdZnTe detector working under high radiation fluxes. We newly demonstrate the influence of a high flux of X-rays and simultaneous 1200-nm LED illumination on the spectroscopic properties of a CdZnTe detector. CdZnTe detectors operating under high radiation fluxes usually suffer from the polarization effect, which occurs due to a screening of the internal electric field by a positive space charge caused by photogenerated holes trapped at a deep level. Polarization results in the degradation of detector charge collection efficiency. We studied the spectroscopic behavior of CdZnTe under various X-ray fluxes ranging between 5 * 10 5 and 8 * 10 6 photons per mm 2 per second. It was observed that polarization occurs at an X-ray flux higher than 3 * 10 6 mm - 2 .s - 1 . Using simultaneous illumination of the detector by a de-polarizing LED at 1200 nm, it was possible to recover X-ray spectra originally deformed by the polarization effect. PMID- 27690025 TI - Analysis of Abnormal Intra-QRS Potentials in Signal-Averaged Electrocardiograms Using a Radial Basis Function Neural Network. AB - Abnormal intra-QRS potentials (AIQPs) are commonly observed in patients at high risk for ventricular tachycardia. We present a method for approximating a measured QRS complex using a non-linear neural network with all radial basis functions having the same smoothness. We extracted the high frequency, but low amplitude intra-QRS potentials using the approximation error to identify possible ventricular tachycardia. With a specified number of neurons, we performed an orthogonal least squares algorithm to determine the center of each Gaussian radial basis function. We found that the AIQP estimation error arising from part of the normal QRS complex could cause clinicians to misjudge patients with ventricular tachycardia. Our results also show that it is possible to correct this misjudgment by combining multiple AIQP parameters estimated using various spread parameters and numbers of neurons. Clinical trials demonstrate that higher AIQP-to-QRS ratios in the X, Y and Z leads are visible in patients with ventricular tachycardia than in normal subjects. A linear combination of 60 AIQP to-QRS ratios can achieve 100% specificity, 90% sensitivity, and 95.8% total prediction accuracy for diagnosing ventricular tachycardia.

AB - A wireless sensor network that consists of nodes with a sound sensor can be used to obtain context awareness in home environments. However, the limited processing power of wireless nodes offers a challenge when extracting features from the signal, and subsequently, classifying the source. Although multiple papers can be found on different methods of sound classification, none of these are aimed at limited hardware or take the efficiency of the algorithms into account. In this paper, we compare and evaluate several classification methods on a real sensor platform using different feature types and classifiers, in order to find an approach that results in a good classifier that can run on limited hardware. To be as realistic as possible, we trained our classifiers using sound waves from many different sources. We conclude that despite the fact that the classifiers are often of low quality due to the highly restricted hardware resources, sufficient performance can be achieved when (1) the window length for our classifiers is increased, and (2) if we apply a two-step approach that uses a refined classification after a global classification has been performed.

AB - Real-time and accurate detection of the sailing or water area will help realize unmanned surface vehicle (USV) systems. Although there are some methods for using optical images in USV-oriented environmental modeling, both the robustness and precision of these published waterline detection methods are comparatively low for a real USV system moving in a complicated environment. This paper proposes an efficient waterline detection method based on structure extraction and texture analysis with respect to optical images and presents a practical application to a USV system for validation. First, the basic principles of local binary patterns (LBPs) and gray level co-occurrence matrix (GLCM) were analyzed, and their advantages were integrated to calculate the texture information of river images. Then, structure extraction was introduced to preprocess the original river images so that the textures resulting from USV motion, wind, and illumination are removed. In the practical application, the waterlines of many images captured by the USV system moving along an inland river were detected with the proposed method, and the results were compared with those of edge detection and super pixel segmentation. The experimental results showed that the proposed algorithm is effective and robust. The average error of the proposed method was 1.84 pixels, and the mean square deviation was 4.57 pixels. PMID- 27690028 TI - Enhanced RGB-D Mapping Method for Detailed 3D Indoor and Outdoor Modeling. AB - RGB-D sensors (sensors with RGB camera and Depth camera) are novel sensing systems that capture RGB images along with pixel-wise depth information. Although they are widely used in various applications, RGB-D sensors have significant drawbacks including limited measurement ranges (e.g., within 3 m) and errors in depth measurement increase with distance from the sensor with respect to 3D dense mapping. In this paper, we present a novel approach to geometrically integrate the depth scene and RGB scene to enlarge the measurement distance of RGB-D sensors and enrich the details of model generated from depth images. First, precise calibration for RGB-D Sensors is introduced. In addition to the calibration of internal and external parameters for both, IR camera and RGB camera, the relative pose between RGB camera and IR camera is also calibrated. Second, to ensure poses accuracy of RGB images, a refined false features matches rejection method is introduced by combining the depth information and initial camera poses between frames of the RGB-D sensor. Then, a global optimization model is used to improve the accuracy of the camera pose, decreasing the inconsistencies between the depth frames in advance. In order to eliminate the geometric inconsistencies between RGB scene and depth scene, the scale ambiguity problem encountered during the pose estimation with RGB image sequences can be resolved by integrating the depth and visual information and a robust rigid transformation recovery method is developed to register RGB scene to depth scene. The benefit of the proposed joint optimization method is firstly evaluated with the publicly available benchmark datasets collected with Kinect. Then, the proposed method is examined by tests with two sets of datasets collected in both outside and inside environments. The experimental results demonstrate the feasibility and robustness of the proposed method. PMID- 27690029 TI - The Design and Analysis of Split Row-Column Addressing Array for 2-D Transducer. AB - For 3-D ultrasound imaging, the row-column addressing (RCA) with 2N connections for an N * N 2-D array makes the fabrication and interconnection simpler than the fully addressing with N2 connections. However, RCA degrades the image quality because of defocusing in signal channel direction in the transmit event. To solve this problem, a split row-column addressing scheme (SRCA) is proposed in this paper. Rather than connecting all the elements in the signal channel direction together, this scheme divides the elements in the signal channel direction into several disconnected blocks, thus enables focusing beam access in both signal channel and switch channel directions. Selecting an appropriate split scheme is the key for SRCA to maintaining a reasonable tradeoff between the image quality and the number of connections. Various split schemes for a 32 * 32 array are fully investigated with point spread function (PSF) analysis and imaging simulation. The result shows the split scheme with five blocks (4, 6, 12, 6, and 4 elements of each block) can provide similar image quality to fully addressing. The splitting schemes for different array sizes from 16 * 16 to 96 * 96 are also discussed. PMID- 27690030 TI - Adaptive Connectivity Restoration from Node Failure(s) in Wireless Sensor Networks. AB - Recently, there is a growing interest in the applications of wireless sensor networks (WSNs). A set of sensor nodes is deployed in order to collectively survey an area of interest and/or perform specific surveillance tasks in some of the applications, such as battlefield reconnaissance. Due to the harsh deployment environments and limited energy supply, nodes may fail, which impacts the connectivity of the whole network. Since a single node failure (cut-vertex) will destroy the connectivity and divide the network into disjoint blocks, most of the existing studies focus on the problem of single node failure. However, the failure of multiple nodes would be a disaster to the whole network and must be repaired effectively. Only few studies are proposed to handle the problem of multiple cut-vertex failures, which is a special case of multiple node failures. Therefore, this paper proposes a comprehensive solution to address the problems of node failure (single and multiple). Collaborative Single Node Failure Restoration algorithm (CSFR) is presented to solve the problem of single node failure only with cooperative communication, but CSFR-M, which is the extension of CSFR, handles the single node failure problem more effectively with node motion. Moreover, Collaborative Connectivity Restoration Algorithm (CCRA) is proposed on the basis of cooperative communication and node maneuverability to restore network connectivity after multiple nodes fail. CSFR-M and CCRA are reactive methods that initiate the connectivity restoration after detecting the node failure(s). In order to further minimize the energy dissipation, CCRA opts to simplify the recovery process by gridding. Moreover, the distance that an individual node needs to travel during recovery is reduced by choosing the nearest suitable candidates. Finally, extensive simulations validate the performance of CSFR, CSFR-M and CCRA. PMID- 27690031 TI - Home Automation System Based on Intelligent Transducer Enablers. AB - This paper presents a novel home automation system named HASITE (Home Automation System based on Intelligent Transducer Enablers), which has been specifically designed to identify and configure transducers easily and quickly. These features are especially useful in situations where many transducers are deployed, since their setup becomes a cumbersome task that consumes a significant amount of time and human resources. HASITE simplifies the deployment of a home automation system by using wireless networks and both self-configuration and self-registration protocols. Thanks to the application of these three elements, HASITE is able to add new transducers by just powering them up. According to the tests performed in different realistic scenarios, a transducer is ready to be used in less than 13 s. Moreover, all HASITE functionalities can be accessed through an API, which also allows for the integration of third-party systems. As an example, an Android application based on the API is presented. Remote users can use it to interact with transducers by just using a regular smartphone or a tablet. PMID- 27690032 TI - Characterization of Screen-Printed Organic Electrochemical Transistors to Detect Cations of Different Sizes. AB - A novel screen-printing fabrication method was used to prepare organic electrochemical transistors (OECTs) based on poly(3,4-ethylenedioxythiophene) doped with polysterene sulfonate (PEDOT:PSS). Initially, three types of these screen-printed OECTs with a different channel and gate areas ratio were compared in terms of output characteristics, transfer characteristics, and current modulation in a phosphate buffered saline (PBS) solution. Results confirm that transistors with a gate electrode larger than the channel exhibit higher modulation. OECTs with this geometry were therefore chosen to investigate their ion-sensitive properties in aqueous solutions of cations of different sizes (sodium and rhodamine B). The effect of the gate electrode was additionally studied by comparing these all-PEDOT:PSS transistors with OECTs with the same geometry but with a non-polarizable metal gate (Ag). The operation of the all PEDOT:PSS OECTs yields a response that is not dependent on a Na+ or rhodamine concentration. The weak modulation of these transistors can be explained assuming that PEDOT:PSS behaves like a supercapacitor. In contrast, the operation of Ag Gate OECTs yields a response that is dependent on ion concentration due to the redox reaction taking place at the gate electrode with Cl- counter-ions. This indicates that, for cation detection, the response is maximized in OECTs with non polarizable gate electrodes. PMID- 27690033 TI - The Usability of a Pressure-Indicating Film to Measure the Teat Load Caused by a Collapsing Liner. AB - Prevention of damage to the teat and mastitis requires determination of the teat load caused by a collapsing liner. The aim of this study was to test a pressure indicating film designed to measure the pressure between a collapsing liner and artificial teats. The Ultra Super Low and the Extreme Low pressure-indicating films were tested on two types of artificial teat. The experiments were performed with a conventional milking cluster equipped with round silicone liners. For each teat and film type, 30 repetitions were performed. Each repetition was performed with a new piece of film. Kruskal-Wallis tests were performed to detect differences between the pressure values for the different teats. The area of regions where pressure-indication color developed was calculated to determine the most suitable film type. Both film types measured the pressure applied to both artificial teats by the teat cup liner. Thus, the pressure-indicating films can be used to measure the pressure between a collapsing liner and an artificial teat. Based on the results of the present investigation, a pressure-indicating film with the measurement ranges of both film types combined would be an optimal tool to measure the overall pressure between an artificial teat and a collapsing liner. PMID- 27690034 TI - Broadband Cooperative Spectrum Sensing Based on Distributed Modulated Wideband Converter. AB - The modulated wideband converter (MWC) is a kind of sub-Nyquist sampling system which is developed from compressed sensing theory. It accomplishes highly accurate broadband sparse signal recovery by multichannel sub-Nyquist sampling sequences. However, when the number of sparse sub-bands becomes large, the amount of sampling channels increases proportionally. Besides, it is very hard to adjust the number of sampling channels when the sparsity changes, because its undersampling board is designed by a given sparsity. Such hardware cost and inconvenience are unacceptable in practical applications. This paper proposes a distributed modulated wideband converter (DMWC) scheme innovatively, which regards one sensor node as one sampling channel and combines MWC technology with a broadband cooperative spectrum sensing network perfectly. Being different from the MWC scheme, DMWC takes phase shift and transmission loss into account in the input terminal, which are unavoidable in practical application. Our scheme is not only able to recover the support of broadband sparse signals quickly and accurately, but also reduces the hardware cost of the single node drastically. Theoretical analysis and numerical simulations show that phase shift has no influence on the recovery of frequency support, but transmission loss degrades the recovery performance to a different extent. Nevertheless, we can increase the amount of cooperative nodes and select satisfactory nodes by a different transmission distance to improve the recovery performance. Furthermore, we can adjust the amount of cooperative nodes flexibly when the sparsity changes. It indicates DMWC is extremely effective in the broadband cooperative spectrum sensing network. PMID- 27690035 TI - Temporal Data-Driven Sleep Scheduling and Spatial Data-Driven Anomaly Detection for Clustered Wireless Sensor Networks. AB - The spatial-temporal correlation is an important feature of sensor data in wireless sensor networks (WSNs). Most of the existing works based on the spatial temporal correlation can be divided into two parts: redundancy reduction and anomaly detection. These two parts are pursued separately in existing works. In this work, the combination of temporal data-driven sleep scheduling (TDSS) and spatial data-driven anomaly detection is proposed, where TDSS can reduce data redundancy. The TDSS model is inspired by transmission control protocol (TCP) congestion control. Based on long and linear cluster structure in the tunnel monitoring system, cooperative TDSS and spatial data-driven anomaly detection are then proposed. To realize synchronous acquisition in the same ring for analyzing the situation of every ring, TDSS is implemented in a cooperative way in the cluster. To keep the precision of sensor data, spatial data-driven anomaly detection based on the spatial correlation and Kriging method is realized to generate an anomaly indicator. The experiment results show that cooperative TDSS can realize non-uniform sensing effectively to reduce the energy consumption. In addition, spatial data-driven anomaly detection is quite significant for maintaining and improving the precision of sensor data. PMID- 27690036 TI - Multi-Frequency Target Detection Techniques for DVB-T Based Passive Radar Sensors. AB - This paper investigates the possibility to improve target detection capability in a DVB-T- based passive radar sensor by jointly exploiting multiple digital television channels broadcast by the same transmitter of opportunity. Based on the remarkable results obtained by such a multi-frequency approach using other signals of opportunity (i.e., FM radio broadcast transmissions), we propose appropriate modifications to the previously devised signal processing techniques for them to be effective in the newly considered scenarios. The resulting processing schemes are extensively applied against experimental DVB-T-based passive radar data pertaining to different surveillance applications. The obtained results clearly show the effectiveness of the proposed multi-frequency approaches and demonstrate their suitability for application in the considered scenarios. PMID- 27690037 TI - Phosphor-Doped Thermal Barrier Coatings Deposited by Air Plasma Spray for In Depth Temperature Sensing. AB - Yttria-stabilized zirconia (YSZ)-based thermal barrier coating (TBC) has been integrated with thermographic phosphors through air plasma spray (APS) for in depth; non-contact temperature sensing. This coating consisted of a thin layer of Dy-doped YSZ (about 40 um) on the bottom and a regular YSZ layer with a thickness up to 300 um on top. A measurement system has been established; which included a portable; low-cost diode laser (405 nm); a photo-multiplier tube (PMT) and the related optics. Coating samples with different topcoat thickness were calibrated in a high-temperature furnace from room temperature to around 900 degrees C. The results convincingly showed that the current sensor and the measurement system was capable of in-depth temperature sensing over 800 degrees C with a YSZ top layer up to 300 um. The topcoat thickness was found to have a strong effect on the luminescent signal level. Therefore; the measurement accuracy at high temperatures was reduced for samples with thick topcoats due to strong light attenuation. However; it seemed that the light transmissivity of YSZ topcoat increased with temperature; which would improve the sensor's performance at high temperatures. The current sensor and the measurement technology have shown great potential in on-line monitoring of TBC interface temperature. PMID- 27690038 TI - A Real-Time Web of Things Framework with Customizable Openness Considering Legacy Devices. AB - With the development of the Internet of Things (IoT), resources and applications based on it have emerged on a large scale. However, most efforts are "silo" solutions where devices and applications are tightly coupled. Infrastructures are needed to connect sensors to the Internet, open up and break the current application silos and move to a horizontal application mode. Based on the concept of Web of Things (WoT), many infrastructures have been proposed to integrate the physical world with the Web. However, issues such as no real-time guarantee, lack of fine-grained control of data, and the absence of explicit solutions for integrating heterogeneous legacy devices, hinder their widespread and practical use. To address these issues, this paper proposes a WoT resource framework that provides the infrastructures for the customizable openness and sharing of users' data and resources under the premise of ensuring the real-time behavior of their own applications. The proposed framework is validated by actual systems and experimental evaluations. PMID- 27690039 TI - An Impedance-Based Mold Sensor with on-Chip Optical Reference. AB - A new miniaturized sensor system with an internal optical reference for the detection of mold growth is presented. The sensor chip comprises a reaction chamber provided with a culture medium that promotes the growth of mold species from mold spores. The mold detection is performed by measuring impedance changes with integrated electrodes fabricated inside the reaction chamber. The impedance change in the culture medium is caused by shifts in the pH (i.e., from 5.5 to 8) as the mold grows. In order to determine the absolute pH value without the need for calibration, a methyl red indicator dye has been added to the culture medium. It changes the color of the medium as the pH passes specific values. This colorimetric principle now acts as a reference measurement. It also allows the sensitivity of the impedance sensor to be established in terms of impedance change per pH unit. Major mold species that are involved in the contamination of food, paper and indoor environments, like Fusarium oxysporum, Fusarium incarnatum, Eurotium amstelodami, Aspergillus penicillioides and Aspergillus restrictus, have been successfully analyzed on-chip. PMID- 27690040 TI - Design of a Sub-Picosecond Jitter with Adjustable-Range CMOS Delay-Locked Loop for High-Speed and Low-Power Applications. AB - A Delay-Locked Loop (DLL) with a modified charge pump circuit is proposed for generating high-resolution linear delay steps with sub-picosecond jitter performance and adjustable delay range. The small-signal model of the modified charge pump circuit is analyzed to bring forth the relationship between the DLL's internal control voltage and output time delay. Circuit post-layout simulation shows that a 0.97 ps delay step within a 69 ps delay range with 0.26 ps Root-Mean Square (RMS) jitter performance is achievable using a standard 0.13 um Complementary Metal-Oxide Semiconductor (CMOS) process. The post-layout simulation results show that the power consumption of the proposed DLL architecture's circuit is 0.1 mW when the DLL is operated at 2 GHz. PMID- 27690041 TI - Colorimetric Integrated PCR Protocol for Rapid Detection of Vibrio parahaemolyticus. AB - Rapid detection of pathogens is of great significance for food safety and disease diagnosis. A new colorimetric method for rapid and easy detection of Vibrio parahaemolyticus (V. parahaemolyticus or Vp) has been developed in this research. A specific sequence was designed and integrated with the forward primer for molecular detection of Vp. This specific sequence was tested and treated as the horseradish peroxidase (HRP)-mimicking DNAzyme and could be amplified during the polymerase chain reaction (PCR) process. The products of PCR including the sequence of HRP-mimicking DNAzyme could produce the distinguished color in the presence of catalysis substrates. The optical signal of the catalysis reaction, which is in a linear relationship with the initial template of Vp, could be determined with the naked eye or measured with Ultraviolet-visible (UV-vis) for qualitative and quantitative detections, respectively. Based on the optical signal intensity, rapid and easy detection of Vp was successfully achieved with satisfied sensitivity and specificity. Furthermore, the detection of tdh, trh, tlh and toxR virulence genes of two Vp species (Vp 33847 and Vp 17802) were all performed successfully with this developed colorimetric integrated PCR protocol, which demonstrated potential applicability for the rapid detection of other bacteria. PMID- 27690042 TI - A Hybrid Secure Scheme for Wireless Sensor Networks against Timing Attacks Using Continuous-Time Markov Chain and Queueing Model. AB - Wireless sensor networks (WSNs) have recently gained popularity for a wide spectrum of applications. Monitoring tasks can be performed in various environments. This may be beneficial in many scenarios, but it certainly exhibits new challenges in terms of security due to increased data transmission over the wireless channel with potentially unknown threats. Among possible security issues are timing attacks, which are not prevented by traditional cryptographic security. Moreover, the limited energy and memory resources prohibit the use of complex security mechanisms in such systems. Therefore, balancing between security and the associated energy consumption becomes a crucial challenge. This paper proposes a secure scheme for WSNs while maintaining the requirement of the security-performance tradeoff. In order to proceed to a quantitative treatment of this problem, a hybrid continuous-time Markov chain (CTMC) and queueing model are put forward, and the tradeoff analysis of the security and performance attributes is carried out. By extending and transforming this model, the mean time to security attributes failure is evaluated. Through tradeoff analysis, we show that our scheme can enhance the security of WSNs, and the optimal rekeying rate of the performance and security tradeoff can be obtained. PMID- 27690043 TI - Fast Industrial Inspection of Optical Thin Film Using Optical Coherence Tomography. AB - An application of spectral domain optical coherence tomography (SD-OCT) was demonstrated for a fast industrial inspection of an optical thin film panel. An optical thin film sample similar to a liquid crystal display (LCD) panel was examined. Two identical SD-OCT systems were utilized for parallel scanning of a complete sample in half time. Dual OCT inspection heads were utilized for transverse (fast) scanning, while a stable linear motorized translational stage was used for lateral (slow) scanning. The cross-sectional and volumetric images of an optical thin film sample were acquired to detect the defects in glass and other layers that are difficult to observe using visual inspection methods. The rapid inspection enabled by this setup led to the early detection of product defects on the manufacturing line, resulting in a significant improvement in the quality assurance of industrial products. PMID- 27690045 TI - Towards Enhanced Gas Sensor Performance with Fluoropolymer Membranes. AB - In this paper we report on how to increase the selectivity of gas sensors by using fluoropolymer membranes. The mass transport of polar and non-polar gases through a polymer membrane matrix was studied by systematic selection of polymers with different degrees of fluorination, as well as polymers whose monomers have ether groups (-O-) in addition to fluorine groups (-F). For the study, a set of application-relevant gases including H2, CO, CO2, NO2, methane, ethanol, acetone, and acetaldehyde as well as various concentrations of relative humidity were used. These gases have different functional groups and polarities, yet have a similar kinetic diameter and are therefore typically difficult to separate. The concentrations of the gases were chosen according to international indicative limit values (TWA, STEL). To measure the concentration in the feed and permeate, we used tin-dioxide-based metal oxide gas sensors with palladium catalyst (SnO2:Pd), catalytic sensors (also SnO2:Pd-based) and thermal conductivity sensors. This allows a close examination of the interdependence of diffusion and physicochemical operating principle of the sensor. Our goal is to increase the selectivity of gas sensors by using inexpensive fluoropolymer membranes. The measurements showed that through membranes with low polarity, preferably non polar gases are transported. Furthermore, the degree of crystallization influences the permeability and selectivity of a polymer membrane. Basically the polar polymers showed a higher permeability to water vapor and polar substances than non-polar polymer membranes. PMID- 27690044 TI - A Toolbox of Genetically Encoded FRET-Based Biosensors for Rapid l-Lysine Analysis. AB - Background: The fast development of microbial production strains for basic and fine chemicals is increasingly carried out in small scale cultivation systems to allow for higher throughput. Such parallelized systems create a need for new rapid online detection systems to quantify the respective target compound. In this regard, biosensors, especially genetically encoded Forster resonance energy transfer (FRET)-based biosensors, offer tremendous opportunities. As a proof-of concept, we have created a toolbox of FRET-based biosensors for the ratiometric determination of l-lysine in fermentation broth. Methods: The sensor toolbox was constructed based on a sensor that consists of an optimized central lysine /arginine-/ornithine-binding protein (LAO-BP) flanked by two fluorescent proteins (enhanced cyan fluorescent protein (ECFP), Citrine). Further sensor variants with altered affinity and sensitivity were obtained by circular permutation of the binding protein as well as the introduction of flexible and rigid linkers between the fluorescent proteins and the LAO-BP, respectively. Results: The sensor prototype was applied to monitor the extracellular l-lysine concentration of the l-lysine producing Corynebacterium glutamicum (C. glutamicum) strain DM1933 in a BioLector(r) microscale cultivation device. The results matched well with data obtained by HPLC analysis and the Ninhydrin assay, demonstrating the high potential of FRET-based biosensors for high-throughput microbial bioprocess optimization. PMID- 27690046 TI - Atmospheric Measurements by Ultra-Light SpEctrometer (AMULSE) Dedicated to Vertical Profile in Situ Measurements of Carbon Dioxide (CO2) Under Weather Balloons: Instrumental Development and Field Application. AB - The concentration of greenhouse gases in the atmosphere plays an important role in the radiative effects in the Earth's climate system. Therefore, it is crucial to increase the number of atmospheric observations in order to quantify the natural sinks and emission sources. We report in this paper the development of a new compact lightweight spectrometer (1.8 kg) called AMULSE based on near infrared laser technology at 2.04 um coupled to a 6-m open-path multipass cell. The measurements were made using the Wavelength Modulation Spectroscopy (WMS) technique and the spectrometer is hence dedicated to in situ measuring the vertical profiles of the CO2 at high precision levels (sigmaAllan = 0.96 ppm in 1 s integration time (1sigma)) and with high temporal/spatial resolution (1 Hz/5 m) using meteorological balloons. The instrument is compact, robust, cost-effective, fully autonomous, has low-power consumption, a non-intrusive probe and is plug & play. It was first calibrated and validated in the laboratory and then used for 17 successful flights up to 10 km altitude in the region Champagne-Ardenne, France in 2014. A rate of 100% of instrument recovery was validated due to the pre-localization prediction of the Meteo-France based on the flight simulation software.

AB - A Fourier transform spectrometer (FTS) that incorporates a closed-loop controlled, electrothermally actuated microelectromechanical systems (MEMS) micromirror is proposed and experimentally verified. The scan range and the tilting angle of the mirror plate are the two critical parameters for MEMS-based FTS. In this work, the MEMS mirror with a footprint of 4.3 mm * 3.1 mm is based on a modified lateral-shift-free (LSF) bimorph actuator design with large piston and reduced tilting. Combined with a position-sensitive device (PSD) for tilt angle sensing, the feedback controlled MEMS mirror generates a 430 um stable linear piston scan with the mirror plate tilting angle less than +/-0.002 degrees . The usable piston scan range is increased to 78% of the MEMS mirror's full scan capability, and a spectral resolution of 0.55 nm at 531.9 nm wavelength, has been achieved. It is a significant improvement compared to the prior work. PMID- 27690048 TI - Planar Indium Tin Oxide Heater for Improved Thermal Distribution for Metal Oxide Micromachined Gas Sensors. AB - Metal oxide gas sensors with integrated micro-hotplate structures are widely used in the industry and they are still being investigated and developed. Metal oxide gas sensors have the advantage of being sensitive to a wide range of organic and inorganic volatile compounds, although they lack selectivity. To introduce selectivity, the operating temperature of a single sensor is swept, and the measurements are fed to a discriminating algorithm. The efficiency of those data processing methods strongly depends on temperature uniformity across the active area of the sensor. To achieve this, hot plate structures with complex resistor geometries have been designed and additional heat-spreading structures have been introduced. In this work we designed and fabricated a metal oxide gas sensor integrated with a simple square planar indium tin oxide (ITO) heating element, by using conventional micromachining and thin-film deposition techniques. Power consumption-dependent surface temperature measurements were performed. A 420 degrees C working temperature was achieved at 120 mW power consumption. Temperature distribution uniformity was measured and a 17 degrees C difference between the hottest and the coldest points of the sensor at an operating temperature of 290 degrees C was achieved. Transient heat-up and cool-down cycle durations are measured as 40 ms and 20 ms, respectively. PMID- 27690049 TI - Development of a Flexible Non-Metal Electrode for Cell Stimulation and Recording. AB - This study presents a method of producing flexible electrodes for potentially simultaneously stimulating and measuring cellular signals in retinal cells. Currently, most multi-electrode applications rely primarily on etching, but the metals involved have a certain degree of brittleness, leaving them prone to cracking under prolonged pressure. This study proposes using silver chloride ink as a conductive metal, and polydimethysiloxane (PDMS) as the substrate to provide electrodes with an increased degree of flexibility to allow them to bend. This structure is divided into the electrode layer made of PDMS and silver chloride ink, and a PDMS film coating layer. PDMS can be mixed in different proportions to modify the degree of rigidity. The proposed method involved three steps. The first segment entailed the manufacturing of the electrode, using silver chloride ink as the conductive material, and using computer software to define the electrode size and micro-engraving mechanisms to produce the electrode pattern. The resulting uniform PDMS pattern was then baked onto the model, and the flow channel was filled with the conductive material before air drying to produce the required electrode. In the second stage, we tested the electrode, using an impedance analyzer to measure electrode cyclic voltammetry and impedance. In the third phase, mechanical and biocompatibility tests were conducted to determine electrode properties. This study aims to produce a flexible, non-metallic sensing electrode which fits snugly for use in a range of measurement applications. PMID- 27690050 TI - Ontology-Based High-Level Context Inference for Human Behavior Identification. AB - Recent years have witnessed a huge progress in the automatic identification of individual primitives of human behavior, such as activities or locations. However, the complex nature of human behavior demands more abstract contextual information for its analysis. This work presents an ontology-based method that combines low-level primitives of behavior, namely activity, locations and emotions, unprecedented to date, to intelligently derive more meaningful high level context information. The paper contributes with a new open ontology describing both low-level and high-level context information, as well as their relationships. Furthermore, a framework building on the developed ontology and reasoning models is presented and evaluated. The proposed method proves to be robust while identifying high-level contexts even in the event of erroneously detected low-level contexts. Despite reasonable inference times being obtained for a relevant set of users and instances, additional work is required to scale to long-term scenarios with a large number of users. PMID- 27690051 TI - Analysis on Target Detection and Classification in LTE Based Passive Forward Scattering Radar. AB - The passive bistatic radar (PBR) system can utilize the illuminator of opportunity to enhance radar capability. By utilizing the forward scattering technique and procedure into the specific mode of PBR can provide an improvement in target detection and classification. The system is known as passive Forward Scattering Radar (FSR). The passive FSR system can exploit the peculiar advantage of the enhancement in forward scatter radar cross section (FSRCS) for target detection. Thus, the aim of this paper is to show the feasibility of passive FSR for moving target detection and classification by experimental analysis and results. The signal source is coming from the latest technology of 4G Long-Term Evolution (LTE) base station. A detailed explanation on the passive FSR receiver circuit, the detection scheme and the classification algorithm are given. In addition, the proposed passive FSR circuit employs the self-mixing technique at the receiver; hence the synchronization signal from the transmitter is not required. The experimental results confirm the passive FSR system's capability for ground target detection and classification. Furthermore, this paper illustrates the first classification result in the passive FSR system. The great potential in the passive FSR system provides a new research area in passive radar that can be used for diverse remote monitoring applications. PMID- 27690052 TI - Integration of Error Compensation of Coordinate Measuring Machines into Feature Measurement: Part I-Model Development. AB - The development of an error compensation model for coordinate measuring machines (CMMs) and its integration into feature measurement is presented. CMMs are widespread and dependable instruments in industry and laboratories for dimensional measurement. From the tip probe sensor to the machine display, there is a complex transformation of probed point coordinates through the geometrical feature model that makes the assessment of accuracy and uncertainty measurement results difficult. Therefore, error compensation is not standardized, conversely to other simpler instruments. Detailed coordinate error compensation models are generally based on CMM as a rigid-body and it requires a detailed mapping of the CMM's behavior. In this paper a new model type of error compensation is proposed. It evaluates the error from the vectorial composition of length error by axis and its integration into the geometrical measurement model. The non-explained variability by the model is incorporated into the uncertainty budget. Model parameters are analyzed and linked to the geometrical errors and uncertainty of CMM response. Next, the outstanding measurement models of flatness, angle, and roundness are developed. The proposed models are useful for measurement improvement with easy integration into CMM signal processing, in particular in industrial environments where built-in solutions are sought. A battery of implementation tests are presented in Part II, where the experimental endorsement of the model is included.

AB - Evidence from behavioral experiments suggests that insects use the skyline as a cue for visual navigation. However, changes of lighting conditions, over hours, days or possibly seasons, significantly affect the appearance of the sky and ground objects. One possible solution to this problem is to extract the "skyline" by an illumination-invariant classification of the environment into two classes, ground objects and sky. In a previous study (Insect models of illumination invariant skyline extraction from UV (ultraviolet) and green channels), we examined the idea of using two different color channels available for many insects (UV and green) to perform this segmentation. We found out that for suburban scenes in temperate zones, where the skyline is dominated by trees and artificial objects like houses, a "local" UV segmentation with adaptive thresholds applied to individual images leads to the most reliable classification. Furthermore, a "global" segmentation with fixed thresholds (trained on an image dataset recorded over several days) using UV-only information is only slightly worse compared to using both the UV and green channel. In this study, we address three issues: First, to enhance the limited range of environments covered by the dataset collected in the previous study, we gathered additional data samples of skylines consisting of minerals (stones, sand, earth) as ground objects. We could show that also for mineral-rich environments, UV-only segmentation achieves a quality comparable to multi spectral (UV and green) segmentation. Second, we collected a wide variety of ground objects to examine their spectral characteristics under different lighting conditions. On the one hand, we found that the special case of diffusely illuminated minerals increases the difficulty to reliably separate ground objects from the sky. On the other hand, the spectral characteristics of this collection of ground objects covers well with the data collected in the skyline databases, increasing, due to the increased variety of ground objects, the validity of our findings for novel environments. Third, we collected omnidirectional images, as often used for visual navigation tasks, of skylines using an UV-reflective hyperbolic mirror. We could show that "local" separation techniques can be adapted to the use of panoramic images by splitting the image into segments and finding individual thresholds for each segment. Contrarily, this is not possible for 'global' separation techniques. PMID- 27690054 TI - Ensemble of One-Class Classifiers for Personal Risk Detection Based on Wearable Sensor Data. AB - This study introduces the One-Class K-means with Randomly-projected features Algorithm (OCKRA). OCKRA is an ensemble of one-class classifiers built over multiple projections of a dataset according to random feature subsets. Algorithms found in the literature spread over a wide range of applications where ensembles of one-class classifiers have been satisfactorily applied; however, none is oriented to the area under our study: personal risk detection. OCKRA has been designed with the aim of improving the detection performance in the problem posed by the Personal RIsk DEtection(PRIDE) dataset. PRIDE was built based on 23 test subjects, where the data for each user were captured using a set of sensors embedded in a wearable band. The performance of OCKRA was compared against support vector machine and three versions of the Parzen window classifier. On average, experimental results show that OCKRA outperformed the other classifiers for at least 0.53% of the area under the curve (AUC). In addition, OCKRA achieved an AUC above 90% for more than 57% of the users.

AB - A number of physical factors can adversely affect cultural heritage. Therefore, monitoring parameters involved in the deterioration process, principally temperature and relative humidity, is useful for preventive conservation. In this study, a total of 15 microclimate stations using open source hardware were developed and stationed at the Mosque-Cathedral of Cordoba, which is registered with UNESCO for its outstanding universal value, to assess the behavior of interior temperature and relative humidity in relation to exterior weather conditions, public hours and interior design. Long-term monitoring of these parameters is of interest in terms of preservation and reducing the costs of future conservation strategies. Results from monitoring are presented to demonstrate the usefulness of this system. PMID- 27690055 TI - Arbitrarily Accessible 3D Microfluidic Device for Combinatorial High-Throughput Drug Screening. AB - Microfluidics-based drug-screening systems have enabled efficient and high throughput drug screening, but their routine uses in ordinary labs are limited due to the complexity involved in device fabrication and system setup. In this work, we report an easy-to-use and low-cost arbitrarily accessible 3D microfluidic device that can be easily adopted by various labs to perform combinatorial assays for high-throughput drug screening. The device is capable of precisely performing automatic and simultaneous reagent loading and aliquoting tasks and performing multistep assays with arbitrary sequences. The device is not intended to compete with other microfluidic technologies regarding ultra-low reaction volume. Instead, its freedom from tubing or pumping systems and easy operation makes it an ideal platform for routine high-throughput drug screening outside traditional microfluidic labs. The functionality and quantitative reliability of the 3D microfluidic device were demonstrated with a histone acetyltransferase-based drug-screening assay using the recombinant Plasmodium falciparum GCN5 enzyme, benchmarked with a traditional microtiter plate-based method. This arbitrarily accessible, multistep capable, low-cost, and easy-to-use device can be widely adopted in various combinatorial assays beyond high throughput drug screening. PMID- 27690057 TI - A Mechatronic Loading Device to Stimulate Bone Growth via a Human Knee. AB - This paper presents the design of an innovative device that applies dynamic mechanical load to human knee joints. Dynamic loading is employed by applying cyclic and periodic force on a target area. The repeated force loading was considered to be an effective modality for repair and rehabilitation of long bones that are subject to ailments like fractures, osteoporosis, osteoarthritis, etc. The proposed device design builds on the knowledge gained in previous animal and mechanical studies. It employs a modified slider-crank linkage mechanism actuated by a brushless Direct Current (DC) motor and provides uniform and cyclic force. The functionality of the device was simulated in a software environment and the structural integrity was analyzed using a finite element method for the prototype construction. The device is controlled by a microcontroller that is programmed to provide the desired loading force at a predetermined frequency and for a specific duration. The device was successfully tested in various experiments for its usability and full functionality. The results reveal that the device works according to the requirements of force magnitude and operational frequency. This device is considered ready to be used for a clinical study to examine whether controlled knee-loading could be an effective regimen for treating the stated bone-related ailments. PMID- 27690058 TI - Vehicle Maneuver Detection with Accelerometer-Based Classification. AB - In the mobile computing era, smartphones have become instrumental tools to develop innovative mobile context-aware systems. In that sense, their usage in the vehicular domain eases the development of novel and personal transportation solutions. In this frame, the present work introduces an innovative mechanism to perceive the current kinematic state of a vehicle on the basis of the accelerometer data from a smartphone mounted in the vehicle. Unlike previous proposals, the introduced architecture targets the computational limitations of such devices to carry out the detection process following an incremental approach. For its realization, we have evaluated different classification algorithms to act as agents within the architecture. Finally, our approach has been tested with a real-world dataset collected by means of the ad hoc mobile application developed. PMID- 27690060 TI - Nanosized Drug Delivery Systems in Gastrointestinal Targeting: Interactions with Microbiota. AB - The new age of nanotechnology has signaled a stream of entrepreneurial possibilities in various areas, form industry to medicine. Drug delivery has benefited the most by introducing nanostructured systems in the transport and controlled release of therapeutic molecules at targeted sites associated with a particular disease. As many nanosized particles reach the gastrointestinal tract by various means, their interactions with the molecular components of this highly active niche are intensively investigated. The well-characterized antimicrobial activities of numerous nanoparticles are currently being considered as a reliable and efficient alternative to the eminent world crisis in antimicrobial drug discovery. The interactions of nanosystems present in the gastrointestinal route with host microbiota is unavoidable; hence, a major research initiative is needed to explore the mechanisms and effects of these nanomaterials on microbiota and the impact that microbiota may have in the outcome of therapies entailing drug delivery nanosystems through the gastrointestinal route. These coordinated studies will provide novel techniques to replace or act synergistically with current technologies and help develop new treatments for major diseases via the discovery of unique antimicrobial molecules. PMID- 27690061 TI - Bioactive Chaetoglobosins from the Mangrove Endophytic Fungus Penicillium chrysogenum. AB - A novel chaetoglobosin named penochalasin I (1) with a unprecedented six-cyclic 6/5/6/5/6/13 fused ring system, and another new chaetoglobosin named penochalasin J (2), along with chaetoglobosins G, F, C, A, E, armochaetoglobosin I, and cytoglobosin C (3-9) were isolated from the culture of Penicillium chrysogenum V11. Their structures were elucidated by 1D, 2D NMR spectroscopic analysis and high resolution mass spectroscopic data. The absolute configuration of compounds 1 and 2 were determined by comparing the theoretical electronic circular dichroism (ECD) calculation with the experimental CD. Compound 1 was the first example, with a six-cyclic fused ring system formed by the connection of C-5 and C-2' of the chaetoglobosin class. Compounds 5-8 remarkably inhibited the plant pathogenic fungus R. solani (minimum inhibitory concentrations (MICs) = 11.79 23.66 MUM), and compounds 2, 6, and 7 greatly inhibited C. gloeosporioides (MICs = 23.58-47.35 MUM), showing an antifungal activity higher than that of carbendazim. Compound 1 exhibited marked cytotoxicity against MDA-MB-435 and SGC 7901 cells (IC50 < 10 MUM), and compounds 6 and 9 showed potent cytotoxicity against SGC-7901 and A549 cells (IC50 < 10 MUM). PMID- 27690059 TI - Lactoferrin from Milk: Nutraceutical and Pharmacological Properties. AB - Lactoferrin is an iron-binding protein present in large quantities in colostrum and in breast milk, in external secretions and in polymorphonuclear leukocytes. Lactoferrin's main function is non-immune protection. Among several protective activities shown by lactoferrin, those displayed by orally administered lactoferrin are: (i) antimicrobial activity, which has been presumed due to iron deprivation, but more recently attributed also to a specific interaction with the bacterial cell wall and extended to viruses and parasites; (ii) immunomodulatory activity, with a direct effect on the development of the immune system in the newborn, together with a specific antinflammatory effects; (iii) a more recently discovered anticancer activity. It is worth noting that most of the protective activities of lactoferrin have been found, sometimes to a greater extent, also in peptides derived from limited proteolysis of lactoferrin that could be generated after lactoferrin ingestion. Lactoferrin could therefore be considered an ideal nutraceutic product because of its relatively cheap production from bovine milk and of its widely recognized tolerance after ingestion, along with its well demonstrated protective activities. The most important protective activities shown by orally administered bovine lactoferrin are reviewed in this article. PMID- 27690063 TI - Empirical Likelihood-Based ANOVA for Trimmed Means. AB - In this paper, we introduce an alternative to Yuen's test for the comparison of several population trimmed means. This nonparametric ANOVA type test is based on the empirical likelihood (EL) approach and extends the results for one population trimmed mean from Qin and Tsao (2002). The results of our simulation study indicate that for skewed distributions, with and without variance heterogeneity, Yuen's test performs better than the new EL ANOVA test for trimmed means with respect to control over the probability of a type I error. This finding is in contrast with our simulation results for the comparison of means, where the EL ANOVA test for means performs better than Welch's heteroscedastic F test. The analysis of a real data example illustrates the use of Yuen's test and the new EL ANOVA test for trimmed means for different trimming levels. Based on the results of our study, we recommend the use of Yuen's test for situations involving the comparison of population trimmed means between groups of interest. PMID- 27690062 TI - Novel Spray Dried Glycerol 2-Phosphate Cross-Linked Chitosan Microparticulate Vaginal Delivery System-Development, Characterization and Cytotoxicity Studies. AB - Chitosan microparticulate delivery systems containing clotrimazole were prepared by a spray drying technique using glycerol 2-phosphate as an ion cross-linker. The impact of a cross-linking ratio on microparticle characteristics was evaluated. Drug-free and drug-loaded unmodified or ion cross-linked chitosan microparticles were examined for the in vitro cytotoxicity in VK2/E6E7 human vaginal epithelial cells. The presence of glycerol 2-phosphate influenced drug loading and encapsulation efficacy in chitosan microparticles. By increasing the cross-linking ratio, the microparticles with lower diameter, moisture content and smoother surface were observed. Mucoadhesive studies displayed that all formulations possessed mucoadhesive properties. The in vitro release profile of clotrimazole was found to alter considerably by changing the glycerol 2 phosphate/chitosan ratio. Results from cytotoxicity studies showed occurrence of apoptotic cells in the presence of chitosan and ion cross-linked chitosan microparticles, followed by a loss of membrane potential suggesting that cell death might go through the mitochondrial apoptotic pathway. PMID- 27690064 TI - The Built Environment-A Missing "Cause of the Causes" of Non-Communicable Diseases. AB - The United Nations "25 * 25 Strategy" of decreasing non-communicable diseases (NCDs), including cardiovascular diseases, diabetes, cancer and chronic respiratory diseases, by 25% by 2025 does not appear to take into account all causes of NCDs. Its focus is on a few diseases, which are often linked with life style factors with "voluntary" "modifiable behavioral risk factors" causes tending towards an over-simplification of the issues. We propose to add some aspects of our built environment related to hazardous building materials, and detailed form of the construction of infrastructure and buildings, which we think are some of the missing causes of NCDs. Some of these could be termed "involuntary causes", as they relate to factors that are beyond the control of the general public. PMID- 27690065 TI - A Case Study of Environmental Injustice: The Failure in Flint. AB - The failure by the city of Flint, Michigan to properly treat its municipal water system after a change in the source of water, has resulted in elevated lead levels in the city's water and an increase in city children's blood lead levels. Lead exposure in young children can lead to decrements in intelligence, development, behavior, attention and other neurological functions. This lack of ability to provide safe drinking water represents a failure to protect the public's health at various governmental levels. This article describes how the tragedy happened, how low-income and minority populations are at particularly high risk for lead exposure and environmental injustice, and ways that we can move forward to prevent childhood lead exposure and lead poisoning, as well as prevent future Flint-like exposure events from occurring. Control of the manufacture and use of toxic chemicals to prevent adverse exposure to these substances is also discussed. Environmental injustice occurred throughout the Flint water contamination incident and there are lessons we can all learn from this debacle to move forward in promoting environmental justice. PMID- 27690066 TI - Relationship between Pesticide Metabolites, Cytokine Patterns, and Asthma-Related Outcomes in Rural Women Workers. AB - The objective of this study was to investigate the relationship between exposure to organophosphate (OP) and pyrethroid (PYR) pesticides with serum cytokine patterns and asthma-related outcomes among rural women workers. A cross-sectional study was conducted among rural women (n = 211), including those working and living on farms and nearby town dwellers. Pesticide exposure was assessed using urinary metabolite concentrations of OP and PYR pesticides. Health outcome assessment was ascertained through the European Community Respiratory Health Survey (ECRHS) questionnaire, fractional exhaled nitric oxide (FeNO), and serum cytokines associated with asthma. The prevalence of doctor-diagnosed asthma was 11%, adult-onset asthma 9%, and current asthma 6%. In this population, the proportion of T helper type 2 (Th2) cytokines (interleukin (IL)-4, IL-5, and IL 13) detectable in subjects was between 18% and 40%, while the proportion of non Th2 cytokines (IL-6, IL-8, IL-10, IL-17, and interferon gamma) was between 35% and 71%. Most Th2 and non-Th2 cytokines were positively associated with either OP or PYR metabolites. Non-Th2 cytokines showed much stronger associations with OP metabolites (Dimethyl phosphate OR = 4.23; 95% CI: 1.54-11.65) than Th2 cytokines (Dimethyl phosphate OR = 1.69; 95% CI: 0.83-3.46). This study suggests that exposure to most OP and some PYR pesticides may be associated with asthma-related cytokines, with non-Th2 cytokines demonstrating consistently stronger relationships. PMID- 27690067 TI - Patterns of Psychiatric Outpatient Practice in Taiwan: A Nationwide Survey. AB - (1) Background: Limited studies have utilized nationwide data to assess the patterns of psychiatric practice in other countries. In this study, data from the National Health Insurance Research Database in Taiwan (NHIRD-TW) for 2012 was analyzed to determine the patterns of psychiatric outpatient practice in Taiwan; (2) Methods: To determine the patterns of psychiatric outpatient practice in Taiwan, the data were drawn from the datasets of Taiwan's National Health Insurance Research Database for 2012, with 619,760 records of outpatient visits representing 1/500 of all the claims in Taiwan for that year. The analysis of psychiatric outpatient visits included patient demographics, diagnoses, and prescribed medications; (3) Results: Neurotic disorders were the most prevalent diagnoses (43.1%, n = 5714). Hypnotics-sedatives and anxiolytics were prescribed in 51.7% (n = 6850) and 39.1% (n = 5181) of psychiatric visits, respectively, with zolpidem being the most commonly prescribed drug (22.6%, n = 2998); and (4) Conclusion: Hypnotics and sedatives were widely prescribed for the outpatient population, and zolpidem had the highest annual prevalence of use. These findings deserve the attention of clinicians and policy makers for monitoring the abuse and dependence of these agents and subsequent adverse events. PMID- 27690068 TI - A Brief Cognitive-Behavioral Psycho-Education (B-CBE) Program for Managing Stress and Anxiety of Main Family Caregivers of Patients in the Intensive Care Unit. AB - Having a loved one in the intensive care unit (ICU) is a stressful event, which may cause a high level of anxiety to the family members. This could threaten their wellbeing and ability to support the patients in, or after discharge from, the ICU. To investigate the outcomes of a brief cognitive-behavioral psycho education program (B-CBE) to manage stress and anxiety of the main family caregivers (MFCs), a pragmatic quasi-experimental study involving 45 participants (treatment group: 24; control group: 21) was conducted in an ICU. The Depression and Anxiety Stress Scale and the Critical Care Family Need Inventory were used to evaluate the primary outcomes on stress and anxiety, and satisfaction with family needs. The treatment group reported significantly better improvement in the information satisfaction score compared to the control group (p < 0.05; eta2 = 0.09). Overall main effects were observed on the stress (p < 0.01; eta2 = 0.20), anxiety (p < 0.01; eta2 = 0.18), depression (p < 0.05; eta2 = 0.13), support satisfaction (p < 0.05; eta2 = 0.13), and comfort satisfaction (p < 0.05; eta2 = 0.11) scores. The experience of this study suggest that MFCs are in great need of additional support like B-CBE to manage their stress and anxiety. Given the brevity of B-CBE, it is practical for critical care nurses to deliver and MFCs to take within the industrious context of an ICU. More studies are needed to investigate these types of brief psychological interventions. PMID- 27690069 TI - Is Multidirectional UV Exposure Responsible for Increasing Melanoma Prevalence with Altitude? A Hypothesis Based on Calculations with a 3D-Human Exposure Model. AB - In a recent study, melanoma incidence rates for Austrian inhabitants living at higher altitudes were found to increase by as much as 30% per 100 m altitude. This strong increase cannot simply be explained by the known increase of erythemally-weighted irradiance with altitude, which ranges between 0.5% and 4% per 100 m. We assume that the discrepancy is partially explainable by upwelling UV radiation; e.g., reflected by snow-covered surfaces. Therefore, we present an approach where the human UV exposure is derived by integrating incident radiation over the 3D geometry of a human body, which enables us to take upwelling radiation into account. Calculating upwelling and downwelling radiance with a radiative transfer model for a snow-free valley and for snow-covered mountain terrain (with albedo of 0.6) yields an increase in UV exposure by 10% per 100 m altitude. The results imply that upwelling radiation plays a significant role in the increase of melanoma incidence with altitude. PMID- 27690070 TI - Has Child Restraint System Use Increased among Parents of Children in Shantou, China? AB - OBJECTIVE: to examine parents' use of child restraint systems (CRS), and determine if parents' knowledge of, attitude toward, and use behavior of child restraint systems have improved following enactment of child restraint use laws in other cities. DESIGN: Observations and a cross-sectional survey of drivers transporting children 17 years and under were conducted at the gate of the schools and parking lots of hospitals in Shantou. Observers recorded the seating location of child passengers, the type of restraint, and appropriate use of CRS and safety belts based on the observation. Knowledge of and attitudes towards use of CRS were reported by the driver following observation. RESULTS: Approximately 6.6% of passengers aged 0-12 were in CRS; rate of forward-facing CRS in children aged 3-5 (9.9%) was higher than rear-facing CRS for children aged 0-2 (1.1%) and booster seat use among children aged 6-12 (0.1%). Children younger than four years old (OR = 3.395, 95% CI = 2.125-5.424), drivers having a college or higher lever education (OR = 2.908, 95% CI = 1.878-4.500) and drivers wearing seatbelt (OR = 3.194, 95% CI = 1.605-6.356) had greater odds of CRS use. Over half (56.6%) of parents might or would use CRS if they could rent CRSs with fees. CONCLUSIONS: The rate of CRS is still low in Shantou. Comprehensive public education programs supported by legislation might be an effective way to improve child passenger safety. Renting CRSs to parents could be a new approach to encourage use. PMID- 27690071 TI - Activity Pattern of Urban Adult Students in an Eastern Mediterranean Society. AB - Knowledge of human activity patterns is needed in air pollution exposure and health risk assessment. However, human activity patterns have never been evaluated in the Eastern Mediterranean societies. Therefore, we investigated the activity pattern of 285 subjects (17-63 years) in Amman, Jordan during October to November, 2015. The subjects spent >80% of their time indoors during weekend days and >85% on workdays. They spent ~4.8% and ~5.7% in transportation during weekend days and workdays, respectively. Males had a different activity pattern than females on weekend days, but both genders had similar activity patterns on workdays. On workdays, males spent less time indoors than females. The activity pattern found in this study is a bit different than that for North Americans and Europeans, who spend more time indoors and in transit. The activity pattern found in this study was very different than that observed for Koreans, who spent about 59% and 67% indoors on workdays and weekend, respectively. The main outcomes of this survey can be utilized in human exposure studies. This study and the upcoming future studies have been encouraged and supported by the regional WHO office in Amman. PMID- 27690072 TI - A Cross-Sectional Study of Tobacco Advertising, Promotion, and Sponsorship in Airports across Europe and the United States. AB - Tobacco advertising, promotion, and sponsorship (TAPS) bans are effective and are increasingly being implemented in a number of venues and countries, yet the state of TAPS in airports and their effect on airport smoking behavior is unknown. The objective of this study was to evaluate the presence of TAPS in airports across Europe and the US, and to begin to examine the relationship between TAPS and smoking behaviors in airports. We used a cross-sectional study design to observe 21 airports in Europe (11) and the US (10). Data collectors observed points of sale for tobacco products, types of products sold, advertisements and promotions, and branding or logos that appeared in the airport. Tobacco products were sold in 95% of all airports, with significantly more sales in Europe than the US. Advertisements appeared mostly in post-security areas; however, airports with advertisements in pre-security areas had significantly more smokers observed outdoors than airports without advertisements in pre-security areas. Tobacco branding appeared in designated smoking rooms as well as on non-tobacco products in duty free shops. TAPS are widespread in airports in Europe and the US and might be associated with outdoor smoking, though further research is needed to better understand any relationship between the two. This study adds to a growing body of research on tobacco control in air transit and related issues. As smoke free policies advance, they should include comprehensive TAPS bans that extend to airport facilities. PMID- 27690073 TI - Temporal Trends in Geographical Variation in Breast Cancer Mortality in China, 1973-2005: An Analysis of Nationwide Surveys on Cause of Death. AB - To describe geographical variation in breast cancer mortality over time, we analysed breast cancer mortality data from three retrospective national surveys on causes of death in recent decades in China. We first calculated the age standardized mortality rate (ASMR) for each of the 31 provinces in mainland China stratified by survey period (1973-1975, 1990-1992 and 2004-2005). To test whether the geographical variation in breast cancer mortality changed over time, we then estimated the rate ratio (RR) for the aggregated data for seven regions and three economic zones using generalized linear models. Finally, we examined the correlation between mortality rate and several macro-economic measures at the provincial level. We found that the overall ASMR increased from 2.98 per 100,000 in 1973-1975 to 3.08 per 100,000 in 1990-1992, and to 3.85 per 100,000 in 2004 2005. Geographical variation in breast cancer mortality also increased significantly over time at the regional level (p = 0.002) but not at the economic zone (p = 0.089) level, with RR being generally lower for Western China (Northwest and Southwest) and higher in Northeast China over the three survey periods. These temporal and spatial trends in breast cancer mortality were found to be correlated with per capita gross domestic product, number of hospitals and health centres' beds per 10,000 population and number of practicing doctors per 10,000 population, and average number of live births for women aged 15-64. It may be necessary to target public health policies in China to address the widening geographic variation in breast cancer mortality, and to take steps to ensure that the ease of access and the quality of cancer care across the country is improved for all residents. PMID- 27690074 TI - Effects of Octylphenol and Bisphenol A on the Metal Cation Transporter Channels of Mouse Placentas. AB - Octylphenol (OP) and bisphenol A (BPA) are known as endocrine-disrupting chemicals (EDCs). During pregnancy, the expression of steroid hormone receptors is controlled by maternal and fetal nutrition. To evaluate the impact of EDCs during pregnancy, ethinyl estradiol (EE, 0.2 mg/kg/day), OP (50 mg/kg/day), and BPA (50 mg/kg/day) were administered to pregnant mice. The mRNA levels of TRPV6 (transient receptor potential cation channels in subfamily V, member 6) decreased significantly by EE and OP. The PMCA1 (ATPase, Ca++ transporting, plasma membrane 1) mRNA and protein levels decreased significantly by EE, OP, and BPA. CTR1 (solute carrier family 31, member 1) and ATP7A (ATPase, Cu++ transporting, alpha polypeptide) expression decreased significantly by EE, OP, and BPA. The mRNA levels of IREG1 (iron-regulated transporter, member 1) decreased significantly by EE. Hephaestin (HEPH) mRNA levels decreased significantly by EE, OP, and BPA, and protein levels decreased significantly by BPA. As a result of immunohistochemistry analysis, all cation transporter proteins were found in labyrinth of placenta. To confirm the cytosolic level of cations, levels of cation level in fetal serum were measured. EE, OP, and BPA significantly reduced serum calcium and copper levels, and iron levels were reduced by BPA. Taken together, some EDCs, such as OP and BPA, could modulate the calcium, copper, and iron ion-transporting channels during pregnancy. The fetus relies on the mother for ionic transportation, and, therefore, pregnant women should avoid exposure to cation-channel-disrupting chemicals. PMID- 27690075 TI - Consensus Modeling for Prediction of Estrogenic Activity of Ingredients Commonly Used in Sunscreen Products. AB - Sunscreen products are predominantly regulated as over-the-counter (OTC) drugs by the US FDA. The "active" ingredients function as ultraviolet filters. Once a sunscreen product is generally recognized as safe and effective (GRASE) via an OTC drug review process, new formulations using these ingredients do not require FDA review and approval, however, the majority of ingredients have never been tested to uncover any potential endocrine activity and their ability to interact with the estrogen receptor (ER) is unknown, despite the fact that this is a very extensively studied target related to endocrine activity. Consequently, we have developed an in silico model to prioritize single ingredient estrogen receptor activity for use when actual animal data are inadequate, equivocal, or absent. It relies on consensus modeling to qualitatively and quantitatively predict ER binding activity. As proof of concept, the model was applied to ingredients commonly used in sunscreen products worldwide and a few reference chemicals. Of the 32 chemicals with unknown ER binding activity that were evaluated, seven were predicted to be active estrogenic compounds. Five of the seven were confirmed by the published data. Further experimental data is needed to confirm the other two predictions. PMID- 27690078 TI - An Examination of the Ethnicity-Specific Prevalence of and Factors Associated with Substance Use and Misuse: Cross-Sectional Analysis of Croatian and Bosniak Adolescents in Bosnia and Herzegovina. AB - Substance use and misuse (SUM) in adolescence is a significant public health problem and the extent to which adolescents exhibit SUM behaviors differs across ethnicity. This study aimed to explore the ethnicity-specific and gender-specific associations among sports factors, familial factors, and personal satisfaction with physical appearance (i.e., covariates) and SUM in a sample of adolescents from Federation of Bosnia and Herzegovina. In this cross-sectional study the participants were 1742 adolescents (17-18 years of age) from Bosnia and Herzegovina who were in their last year of high school education (high school seniors). The sample comprised 772 Croatian (558 females) and 970 Bosniak (485 females) adolescents. Variables were collected using a previously developed and validated questionnaire that included questions on SUM (alcohol drinking, cigarette smoking, and consumption of other drugs), sport factors, parental education, socioeconomic status, and satisfaction with physical appearance and body weight. The consumption of cigarettes remains high (37% of adolescents smoke cigarettes), with a higher prevalence among Croatians. Harmful drinking is also alarming (evidenced in 28.4% of adolescents). The consumption of illicit drugs remains low with 5.7% of adolescents who consume drugs, with a higher prevalence among Bosniaks. A higher likelihood of engaging in SUM is found among children who quit sports (for smoking and drinking), boys who perceive themselves to be good looking (for smoking), and girls who are not satisfied with their body weight (for smoking). Higher maternal education is systematically found to be associated with greater SUM in Bosniak girls. Information on the associations presented herein could be discretely disseminated as a part of regular school administrative functions. The results warrant future prospective studies that more precisely identify the causality among certain variables. PMID- 27690077 TI - Are Non-Pharmacological Interventions Effective in Reducing Drug Use and Criminality? A Systematic and Meta-Analytical Review with an Economic Appraisal of These Interventions. AB - Background: The numbers of incarcerated people suffering from drug dependence has steadily risen since the 1980s and only a small proportion of these receive appropriate treatment. A systematic review to evaluate the effectiveness and economic evidence of non-pharmacological interventions for drug using offenders was conducted. Methods: Cochrane Collaboration criteria were used to identify trials across 14 databases between 2004 and 2014. A series of meta-analyses and an economic appraisal were conducted. Results: 43 trials were identified showing to have limited effect in reducing re-arrests RR 0.97 (95% CI 0.89-1.07) and drug use RR 0.90 (95% CI 0.80-1.00) but were found to significantly reduce re incarceration RR 0.70 (95% CI 0.57-0.85). Therapeutic community programs were found to significantly reduce the number of re-arrests RR 0.70 (95% CI 0.56 0.87). 10 papers contained economic information. One paper presented a cost benefit analysis and two reported on the cost and cost effectiveness of the intervention. Conclusions: We suggest that therapeutic community interventions have some benefit in reducing subsequent re-arrest. We recommend that economic evaluations should form part of standard trial protocols.

AB - The antioxidant properties of l-arginine (l-Arg) in vivo, and its effect on enhancing resistance to oxidative stress and heat stress in Caenorhabditis elegans were investigated. C. elegans, a worm model popularly used in molecular and developmental biology, was used in the present study. Here, we report that l Arg, at a concentration of 1 mM, prolonged C. elegans life by 26.98% and 37.02% under oxidative and heat stress, respectively. Further experiments indicated that the longevity-extending effects of l-Arg may be exerted by its free radical scavenging capacity and the upregulation of aging-associated gene expression in worms. This work is important in the context of numerous recent studies that concluded that environment stresses are associated with an increased population death rate. PMID- 27690076 TI - Bioelectromagnetics Research within an Australian Context: The Australian Centre for Electromagnetic Bioeffects Research (ACEBR). AB - Mobile phone subscriptions continue to increase across the world, with the electromagnetic fields (EMF) emitted by these devices, as well as by related technologies such as Wi-Fi and smart meters, now ubiquitous. This increase in use and consequent exposure to mobile communication (MC)-related EMF has led to concern about possible health effects that could arise from this exposure. Although much research has been conducted since the introduction of these technologies, uncertainty about the impact on health remains. The Australian Centre for Electromagnetic Bioeffects Research (ACEBR) is a National Health and Medical Research Council Centre of Research Excellence that is undertaking research addressing the most important aspects of the MC-EMF health debate, with a strong focus on mechanisms, neurodegenerative diseases, cancer, and exposure dosimetry. This research takes as its starting point the current scientific status quo, but also addresses the adequacy of the evidence for the status quo. Risk communication research complements the above, and aims to ensure that whatever is found, it is communicated effectively and appropriately. This paper provides a summary of this ACEBR research (both completed and ongoing), and discusses the rationale for conducting it in light of the prevailing science. PMID- 27690080 TI - Vesicular Nucleo-Cytoplasmic Transport-Herpesviruses as Pioneers in Cell Biology. AB - Herpesviruses use a vesicle-mediated transfer of intranuclearly assembled nucleocapsids through the nuclear envelope (NE) for final maturation in the cytoplasm. The molecular basis for this novel vesicular nucleo-cytoplasmic transport is beginning to be elucidated in detail. The heterodimeric viral nuclear egress complex (NEC), conserved within the classical herpesviruses, mediates vesicle formation from the inner nuclear membrane (INM) by polymerization into a hexagonal lattice followed by fusion of the vesicle membrane with the outer nuclear membrane (ONM). Mechanisms of capsid inclusion as well as vesicle-membrane fusion, however, are largely unclear. Interestingly, a similar transport mechanism through the NE has been demonstrated in nuclear export of large ribonucleoprotein complexes during Drosophila neuromuscular junction formation, indicating a widespread presence of a novel concept of cellular nucleo-cytoplasmic transport. PMID- 27690081 TI - Molecular Characterization of a Trisegmented Mycovirus from the Plant Pathogenic Fungus Colletotrichum gloeosporioides. AB - A novel double-stranded RNA (dsRNA) mycovirus, consisting of three dsRNA genome segments and possibly belonging to the family Chrysoviridae, was isolated from the filamentous phytopathogenic fungus Colletotrichum gloeosporioides and designated as Colletotrichum gloeosprioides chrysovirus 1 (CgCV1). The three dsRNAs of the CgCV1 genome with lengths of 3397, 2869, and 2630 bp (dsRNAs1-3) were found to contain a single open reading frame (ORF) putatively encoding the RNA-dependent RNA polymerase (RdRp), a capsid protein, and a protease, respectively, all of which exhibited some degree of sequence similarity to the comparable putative proteins encoded by the genus Chrysovirus. The 5'- and 3' untranslated regions in each dsRNA segment contained similar sequences that were strictly conserved at the termini. Moreover, isometric virus-like particles (VLPs) with a diameter of approximately 40 nm were extracted from fungal mycelia. Phylogenetic analysis based on the conserved dsRNA1-encoded RdRp showed that CgCV1 is a new virus belonging to the Chrysoviridae family. BLAST analysis revealed the presence of CgCV1-like sequences in the chromosomes of Medicago truncatula and Solanum tuberosum. Moreover, some sequences in the transcriptome shotgun assembly (TSA) library and expressed sequence tag database (ESTdb) of other eudicot and monocot plants were also found to be related to CgCV1. PMID- 27690083 TI - The VP1u Receptor Restricts Parvovirus B19 Uptake to Permissive Erythroid Cells. AB - Parvovirus B19 (B19V) is a small non-enveloped virus and known as the causative agent for the mild childhood disease erythema infectiosum. B19V has an extraordinary narrow tissue tropism, showing only productive infection in erythroid precursor cells in the bone marrow. We recently found that the viral protein 1 unique region (VP1u) contains an N-terminal receptor-binding domain (RBD), which mediates the uptake of the virus into cells of the erythroid lineage. To further investigate the role of the RBD in connection with a B19V unrelated capsid, we chemically coupled the VP1u of B19V to the bacteriophage MS2 capsid and tested the internalization capacity of the bioconjugate on permissive cells. In comparison, we studied the cellular uptake and infection of B19V along the erythroid differentiation. The results showed that the MS2-VP1u bioconjugate mimicked the specific internalization of the native B19V into erythroid precursor cells, which further coincides with the restricted infection profile. The successful mimicry of B19V uptake demonstrates that the RBD in the VP1u is sufficient for the endocytosis of the viral capsid. Furthermore, the recombinant VP1u competed with B19V uptake into permissive cells, thus excluding a significant alternative uptake mechanism by other receptors. Strikingly, the VP1u receptor appeared to be expressed only on erythropoietin-dependent erythroid differentiation stages that also provide the necessary intracellular factors for a productive infection. Taken together, these findings suggest that the VP1u binds to a yet-unknown erythroid-specific cellular receptor and thus restricts the virus entry to permissive cells. PMID- 27690082 TI - Structural Maturation of HIV-1 Reverse Transcriptase-A Metamorphic Solution to Genomic Instability. AB - Human immunodeficiency virus 1 (HIV-1) reverse transcriptase (RT)-a critical enzyme of the viral life cycle-undergoes a complex maturation process, required so that a pair of p66 precursor proteins can develop conformationally along different pathways, one evolving to form active polymerase and ribonuclease H (RH) domains, while the second forms a non-functional polymerase and a proteolyzed RH domain. These parallel maturation pathways rely on the structural ambiguity of a metamorphic polymerase domain, for which the sequence-structure relationship is not unique. Recent nuclear magnetic resonance (NMR) studies utilizing selective labeling techniques, and structural characterization of the p66 monomer precursor have provided important insights into the details of this maturation pathway, revealing many aspects of the three major steps involved: (1) domain rearrangement; (2) dimerization; and (3) subunit-selective RH domain proteolysis. This review summarizes the major structural changes that occur during the maturation process. We also highlight how mutations, often viewed within the context of the mature RT heterodimer, can exert a major influence on maturation and dimerization. It is further suggested that several steps in the RT maturation pathway may provide attractive targets for drug development. PMID- 27690084 TI - Emergence of a Latent Indian Cassava Mosaic Virus from Cassava Which Recovered from Infection by a Non-Persistent Sri Lankan Cassava Mosaic Virus. AB - The major threat for cassava cultivation on the Indian subcontinent is cassava mosaic disease (CMD) caused by cassava mosaic geminiviruses which are bipartite begomoviruses with DNA A and DNA B components. Indian cassava mosaic virus (ICMV) and Sri Lankan cassava mosaic virus (SLCMV) cause CMD in India. Two isolates of SLCMV infected the cassava cultivar Sengutchi in the fields near Malappuram and Thiruvananthapuram cities of Kerala State, India. The Malappuram isolate was persistent when maintained in the Madurai Kamaraj University (MKU, Madurai, Tamil Nadu, India) greenhouse, whereas the Thiruvananthapuram isolate did not persist. The recovered cassava plants with the non-persistent SLCMV, which were maintained vegetative in quarantine in the University of Basel (Basel, Switzerland) greenhouse, displayed re-emergence of CMD after a six-month period. Interestingly, these plants did not carry SLCMV but carried ICMV. It is interpreted that the field-collected, SLCMV-infected cassava plants were co infected with low levels of ICMV. The loss of SLCMV in recovered cassava plants, under greenhouse conditions, then facilitated the re-emergence of ICMV. The partial dimer clones of the persistent and non-persistent isolates of SLCMV and the re-emerged isolate of ICMV were infective in Nicotiana benthamiana upon agroinoculation. Studies on pseudo-recombination between SLCMV and ICMV in N. benthamiana provided evidence for trans-replication of ICMV DNA B by SLCMV DNA A. PMID- 27690085 TI - Enhanced Replication of Hepatitis E Virus Strain 47832c in an A549-Derived Subclonal Cell Line. AB - Hepatitis E virus (HEV) is a human pathogen with increasing importance. The lack of efficient cell culture systems hampers systematic studies on its replication cycle, virus neutralization and inactivation. Here, several cell lines were inoculated with the HEV genotype 3c strain 47832c, previously isolated from a chronically infected transplant patient. At 14 days after inoculation the highest HEV genome copy numbers were found in A549 cells, followed by PLC/PRF/5 cells, whereas HepG2/C3A, Huh-7 Lunet BLR and MRC-5 cells only weakly supported virus replication. Inoculation of A549-derived subclone cell lines resulted in most cases in reduced HEV replication. However, the subclone A549/D3 was susceptible to lower virus concentrations and resulted in higher virus yields as compared to parental A549 cells. Transcriptome analysis indicated a downregulation of genes for carcinoembryonic antigen-related cell adhesion molecules (CEACAM) 5 and 6, and an upregulation of the syndecan 2 (SDC2) gene in A549/D3 cells compared to A549 cells. However, treatment of A549/D3 cells or A549 cells with CEACAM- or syndecan 2-specific antisera did not influence HEV replication. The results show that cells supporting more efficient HEV replication can be selected from the A549 cell line. The specific mechanisms responsible for the enhanced replication remain unknown. PMID- 27690087 TI - A Trypsin Inhibitor from Tamarind Reduces Food Intake and Improves Inflammatory Status in Rats with Metabolic Syndrome Regardless of Weight Loss. AB - Trypsin inhibitors are studied in a variety of models for their anti-obesity and anti-inflammatory bioactive properties. Our group has previously demonstrated the satietogenic effect of tamarind seed trypsin inhibitors (TTI) in eutrophic mouse models and anti-inflammatory effects of other trypsin inhibitors. In this study, we evaluated TTI effect upon satiety, biochemical and inflammatory parameters in an experimental model of metabolic syndrome (MetS). Three groups of n = 5 male Wistar rats with obesity-based MetS received for 10 days one of the following: (1) Cafeteria diet; (2) Cafeteria diet + TTI (25 mg/kg); and (3) Standard diet. TTI reduced food intake in animals with MetS. Nevertheless, weight gain was not different between studied groups. Dyslipidemia parameters were not different with the use of TTI, only the group receiving standard diet showed lower very low density lipoprotein (VLDL) and triglycerides (TG) (Kruskal-Wallis, p < 0.05). Interleukin-6 (IL-6) production did not differ between groups. Interestingly, tumor necrosis factor-alpha (TNF-alpha) was lower in animals receiving TTI. Our results corroborate the satietogenic effect of TTI in a MetS model. Furthermore, we showed that TTI added to a cafeteria diet may decrease inflammation regardless of weight loss. This puts TTI as a candidate for studies to test its effectiveness as an adjuvant in MetS treatment. PMID- 27690088 TI - The Growth of SGC-7901 Tumor Xenografts Was Suppressed by Chinese Bayberry Anthocyanin Extract through Upregulating KLF6 Gene Expression. AB - To investigate the antitumor effect of anthocyanins extracted from Chinese bayberry fruit (Myrica rubra Sieb. et Zucc.), a nude mouse tumor xenograft model was established. Treatments with C3G (cyanidin-3-glucoside, an anthocyanin) significantly suppressed the growth of SGC-7901 tumor xenografts in a dose dependent manner. Immunohistochemical staining showed a significant increase in p21 expression, indicating that the cell cycle of tumor xenografts was inhibited. qPCR screening showed that C3G treatment up-regulated the expression of the KLF6 gene, which is an important tumor suppressor gene inactivated in many human cancers. Western blot showed that C3G treatments markedly increased KLF6 and p21 protein levels, inhibited CDK4 and Cyclin D1 expression, but did not notably change the expression of p53. These results indicated that KLF6 up-regulates p21 in a p53-independent manner and significantly reduces tumor proliferation. This study provides important information for the possible mechanism of C3G-induced antitumor activity against gastric adenocarcinoma in vivo.

AB - Globally, childhood undernutrition continues to be a major public health concern, with an estimated 165 million children classified as stunted and 51.5 million suffering from acute malnutrition.[...]. PMID- 27690089 TI - Immune-Enhancing Effects of a High Molecular Weight Fraction of Cynanchum wilfordii Hemsley in Macrophages and Immunosuppressed Mice. AB - The objective of this study was to investigate the immune-enhancing activity of a high molecular weight fraction (HMF) of Cynanchum wilfordii in RAW 264.7 macrophages and the cyclophosphamide (CYC)-induced mouse model of immunosuppression. To identify the bioactive substances of HMF, a crude polysaccharide (HMFO) was obtained and treated with sodium periodate (an oxidation agent) or digested with protease. In macrophages, HMF treatment enhanced the production of nitric oxide (NO) and cytokines (tumor necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6), and interleukin 1beta (IL-1beta)), as well as phagocytic ability. In CYC-immunosuppressed mice, HMF improved relative spleen and thymus weights, natural killer (NK) cell activity, and splenic lymphocyte proliferation. These increases in NO and cytokines were mediated by up regulation of nuclear factor kappa B (NF-kappaB) and mitogen-activated protein kinase (MAPK) signaling pathways. Periodate treatment, but not protease treatment, decreased the immune-enhancing activity of HMFO, suggesting that polysaccharides are the active ingredients in C. wilfordii extract. PMID- 27690086 TI - Multi-Omics Studies towards Novel Modulators of Influenza A Virus-Host Interaction. AB - Human influenza A viruses (IAVs) cause global pandemics and epidemics. These viruses evolve rapidly, making current treatment options ineffective. To identify novel modulators of IAV-host interactions, we re-analyzed our recent transcriptomics, metabolomics, proteomics, phosphoproteomics, and genomics/virtual ligand screening data. We identified 713 potential modulators targeting 199 cellular and two viral proteins. Anti-influenza activity for 48 of them has been reported previously, whereas the antiviral efficacy of the 665 remains unknown. Studying anti-influenza efficacy and immuno/neuro-modulating properties of these compounds and their combinations as well as potential viral and host resistance to them may lead to the discovery of novel modulators of IAV host interactions, which might be more effective than the currently available anti-influenza therapeutics. PMID- 27690091 TI - Intakes of Folate and Vitamin B12 and Biomarkers of Status in the Very Old: The Newcastle 85+ Study. AB - Very old adults are at increased risk of folate and vitamin B12 deficiencies due to reduced food intake and gastrointestinal absorption. The main aim was to determine the association between folate and vitamin B12 intake from total diets and food groups, and status. Folate or vitamin B12 intakes (2 * 24 h multiple pass recalls) and red blood cell (RBC) folate or plasma vitamin B12 (chemiluminescence immunoassays) concentrations were available at baseline for 731 participants aged 85 from the Newcastle 85+ Study (North-East England). Generalized additive and binary logistic models estimated the associations between folate and vitamin B12 intakes from total diets and food groups, and RBC folate and plasma B12. Folate intake from total diets and cereal and cereal products was strongly associated with RBC folate (p < 0.001). Total vitamin B12 intake was weakly associated with plasma vitamin B12 (p = 0.054) but those with higher intakes from total diets or meat and meat products were less likely to have deficient status. Women homozygous for the FUT2 G allele had higher concentrations of plasma vitamin B12. Cereals and cereal products are a very important source of folate in the very old. Higher intakes of folate and vitamin B12 lower the risk of "inadequate" status. PMID- 27690092 TI - Food and Nutrient Intake among 12-Month-Old Norwegian-Somali and Norwegian-Iraqi Infants. AB - The aim of the present paper was to describe food and nutrient intake among 12 month-old Norwegian-Somali and Norwegian-Iraqi infants, with a focus on iron and vitamin D intake. A cross-sectional survey was conducted from August 2013 through September 2014. Eighty-nine mothers/infants of Somali origin and 77 mothers/infants of Iraqi origin residing in Eastern Norway participated in the study. Data were collected using two 24-h multiple-pass recalls. Forty percent of the Norwegian-Somali infants and 47% of the Norwegian-Iraqi infants were breastfed at 12 months of age (p = 0.414). Median energy percentages (E%) from protein, fat and carbohydrates were within the recommended intake ranges, except the level of saturated fats (12-13 E%). Median intakes of almost all micronutrients were above the recommended daily intakes. Most of the infants consumed iron-enriched products (81%) and received vitamin D supplements (84%). The median intakes of iron and vitamin D were significantly higher among infants receiving iron-enriched products and vitamin D supplements compared to infants not receiving such products (p < 0.001). The findings indicate that the food and nutrient intake of this group of infants in general seems to be in accordance with Norwegian dietary recommendations. Foods rich in iron and vitamin D supplements were important sources of the infants' intake of iron and vitamin D and should continue to be promoted. PMID- 27690093 TI - Efficacy of Synbiotics in Patients with Slow Transit Constipation: A Prospective Randomized Trial. AB - Synbiotic intake may efficiently restore the balance of gut microbiota and improve gastrointestinal functions. The aim of the study was to evaluate the efficacy of a synbiotic in patients with slow transit constipation. A total of 100 patients with slow transit constipation were randomized to receive either a synbiotic or placebo twice daily for 12 weeks. The primary efficacy endpoints were the clinical remission and improvement rates at weeks 4 and 12. Stool frequency and consistency, colonic transit time (CTT), evacuation and abdominal symptoms, patient assessment of constipation symptoms, gastrointestinal quality of-life index scores, satisfaction scores, and adverse events were also monitored. The clinical remission rates reached 37.5% at week 4 and 45.8% at week 12 in the treatment group, compared to 13.3% at week 4 and 16.7% at week 12 in the placebo group (p < 0.01 for both comparisons). Over 12 weeks, 64.6% of the patients who received the synbiotic experienced clinical improvement, compared to 29.2% of the patients in the placebo group (p < 0.01). During the intervention period, patients who were treated with the synbiotic exhibited increased stool frequency, improved stool consistency, decreased CTT, and improved constipation related symptoms. This randomized, placebo-controlled trial suggested that dietary supplementation with a synbiotic improved evacuation-parameters associated symptoms and colonic motility in patients with slow transit constipation (STC). PMID- 27690094 TI - Amino Acid Composition of Breast Milk from Urban Chinese Mothers. AB - Human breast milk (BM) amino acid (AA) composition may be impacted by lactation stage or factors related to geographical location. The present cross-sectional study is aimed at assessing the temporal changes of BMAA over lactation stages in a large cohort of urban mothers in China. Four hundred fifty BM samples, collected in three Chinese cities covering eight months of lactation were analyzed for free (FAA) and total (TAA) AA by o-phthalaldehyde/ fluorenylmethylchloroformate (OPA/FMOC) derivatization. Concentrations and changes over lactation were aligned with previous reports. Both the sum and the individual TAA values significantly decreased during the first periods of lactation and then generally leveled off. Leucine and methionine were respectively the most and the least abundant indispensable amino acids across all the lactation stages, whereas glutamic acid + glutamine (Glx) was the most and cystine the least abundant dispensable AA. The contribution of FAA to TAA levels was less than 2%, except for free Glx, which was the most abundant FAA. In conclusion, the AA composition of the milk from our cohort of urban Chinese mothers was comparable to previous studies conducted in other parts of the world, suggesting that this is an evolutionary conserved trait largely independent of geographical, ethnic, or dietary factors. PMID- 27690095 TI - The VITAH Trial-Vitamin D Supplementation and Cardiac Autonomic Tone in Patients with End-Stage Kidney Disease on Hemodialysis: A Blinded, Randomized Controlled Trial. AB - : End-stage kidney disease (ESKD) patients are at increased cardiovascular risk. Vitamin D deficiency is associated with depressed heart rate variability (HRV), a risk factor depicting poor cardiac autonomic tone and risk of cardiovascular death. Vitamin D deficiency and depressed HRV are highly prevalent in the ESKD population. We aimed to determine the effects of oral vitamin D supplementation on HRV ((low frequency (LF) to high frequency (HF) spectral ratio (LF:HF)) in ESKD patients on hemodialysis. Fifty-six subjects with ESKD requiring hemodialysis were recruited from January 2013-March 2015 and randomized 1:1 to either conventional (0.25 mcg alfacalcidol plus placebo 3*/week) or intensive (0.25 mcg alfacalcidol 3*/week plus 50,000 international units (IU) ergocalciferol 1*/week) vitamin D for six weeks. The primary outcome was the change in LF:HF. There was no difference in LF:HF from baseline to six weeks for either vitamin D treatment (conventional: p = 0.9 vs. baseline; intensive: p = 0.07 vs. baseline). However, participants who remained vitamin D-deficient (25 hydroxyvitamin D < 20 ng/mL) after treatment demonstrated an increase in LF:HF (conventional: n = 13, ?LF:HF: 0.20 +/- 0.06, p < 0.001 vs. insufficient and sufficient vitamin D groups; intensive: n = 8: ?LF:HF: 0.15 +/- 0.06, p < 0.001 vs. sufficient vitamin D group). Overall, six weeks of conventional or intensive vitamin D only augmented LF:HF in ESKD subjects who remained vitamin D-deficient after treatment. Our findings potentially suggest that while activated vitamin D, with or without additional nutritional vitamin D, does not appear to improve cardiac autonomic tone in hemodialysis patients with insufficient or sufficient baseline vitamin D levels, supplementation in patients with severe vitamin D deficiency may improve cardiac autonomic tone in this higher risk sub-population of ESKD.

PMID- 27690096 TI - Effects of n-3 PUFAs on Intestinal Mucosa Innate Immunity and Intestinal Microbiota in Mice after Hemorrhagic Shock Resuscitation. AB - n-3 polyunsaturated fatty acids (PUFAs) can improve the function of the intestinal barrier after damage from ischemia-reperfusion or hemorrhagic shock resuscitation (HSR). However, the effects of n-3 PUFAs on intestinal microbiota and the innate immunity of the intestinal mucosa after HSR remain unclear. In the present study, 40 C57BL/6J mice were randomly assigned to five groups: control, sham, HSR, HSR + n-3 PUFAs and HSR + n-6 PUFAs. Mice were sacrificed 12 h after HSR. Liver, spleen, mesenteric lymph nodes and terminal ileal tissues were collected. Intestinal mucosae were scraped aseptically. Compared with the HSR group, the number of goblet cells increased, expression of mucin 2 was restored and disturbed intestinal microbiota were partly stabilized in the PUFA administered groups, indicating that both n-3 and n-6 PUFAs reduced overproliferation of Gammaproteobacteria while promoting the growth of Bacteroidetes. Notably, n-3 PUFAs had an advantage over n-6 PUFAs in improving ileal tissue levels of lysozyme after HSR. Thus, PUFAs, especially n-3 PUFAs, partly improved the innate immunity of intestinal mucosa in mice after HSR. These findings suggest a clinical rationale for providing n-3 PUFAs to patients recovering from ischemia-reperfusion. PMID- 27690097 TI - Vitamin D Intake and Serum 25-Hydroxyvitamin D Levels in Korean Adults: Analysis of the 2009 Korea National Health and Nutrition Examination Survey (KNHANES IV-3) Using a Newly Established Vitamin D Database. AB - Vitamin D is important for maintaining bone health and may prevent various diseases (i.e., cardiovascular disease and cancer). The aim of this study was to estimate vitamin D intakes of Korean adults using the Korea National Health and Nutrition Examination Survey (KNHANES, 2009) data and a newly established vitamin D database. KNHANES (2009) participants (n = 4541; 2021 men; 2520 women) aged >=20 years were included. Dietary vitamin D intake, serum 25-hydroxyvitamin D (25(OH)D), and the relationship between vitamin D intake and serum 25(OH)D were evaluated. In men and women, vitamin D intakes were 4.00 +/- 0.17 ug/day and 2.6 +/- 0.1 ug/day respectively, and serum 25(OH)D concentrations were 19.78 +/- 0.33 ng/mL and 17.10 +/- 0.26 ng/mL respectively. Serum 25(OH)D concentrations of men aged <50 years and women aged >20 years were under 20 ng/mL. After adjusting for confounding factors, the positive relationship between vitamin D intake and serum 25(OH)D was observed in total subjects (p < 0.05), excluding participants >=50 years old. The main food sources for vitamin D among Korean adults were fish/shellfish (71.34%) and egg (14.89%). Korean adults should increase their serum 25(OH)D concentrations by increasing vitamin D intake. PMID- 27690098 TI - BmP02 Atypically Delays Kv4.2 Inactivation: Implication for a Unique Interaction between Scorpion Toxin and Potassium Channel. AB - BmP02, a short-chain peptide with 28 residues from the venom of Chinese scorpion Buthus martensi Karsch, has been reported to inhibit the transient outward potassium currents (Ito) in rat ventricular muscle cells. However, it remains unclear whether BmP02 modulates the Kv4.2 channel, one of the main contributors to Ito. The present study investigated the effects of BmP02 on Kv4.2 kinetics and its underlying molecular mechanism. The electrophysiological recordings showed that the inactivation of Kv4.2 expressed in HEK293T cells was significantly delayed by BmP02 in a dose-response manner with EC50 of ~850 nM while the peak current, activation and voltage-dependent inactivation of Kv4.2 were not affected. Meanwhile, the recovery from inactivation of Kv4.2 was accelerated and the deactivation was slowed after the application of BmP02. The site-directed mutagenesis combined with computational modelling identified that K347 and K353, located in the turret motif of the Kv4.2, and E4/E5, D20/D21 in BmP02 are key residues to interact with BmP02 through electrostatic force. These findings not only reveal a novel interaction between Kv4.2 channel and its peptidyl modulator, but also provide valuable information for design of highly-selective Kv4.2 modulators. PMID- 27690099 TI - Ex Vivo Smooth Muscle Pharmacological Effects of a Novel Bradykinin-Related Peptide, and Its Analogue, from Chinese Large Odorous Frog, Odorrana livida Skin Secretions. AB - Bradykinin-related peptides (BRPs) are one of the most extensively studied frog secretions-derived peptide families identified from many amphibian species. The diverse primary structures of BRPs have been proven essential for providing valuable information in understanding basic mechanisms associated with drug modification. Here, we isolated, identified and characterized a dodeca-BRP (RAP L1, T6-BK), with primary structure RAPLPPGFTPFR, from the skin secretions of Chinese large odorous frogs, Odorrana livida. This novel peptide exhibited a dose dependent contractile property on rat bladder and rat ileum, and increased the contraction frequency on rat uterus ex vivo smooth muscle preparations; it also showed vasorelaxant activity on rat tail artery smooth muscle. In addition, the analogue RAP-L1, T6, L8-BK completely abolished these effects on selected rat smooth muscle tissues, whilst it showed inhibition effect on bradykinin-induced rat tail artery relaxation. By using canonical antagonist for bradykinin B1 or B2 type receptors, we found that RAP-L1, T6-BK -induced relaxation of the arterial smooth muscle was very likely to be modulated by B2 receptors. The analogue RAP L1, T6, L8-BK further enhanced the bradykinin inhibitory activity only under the condition of co-administration with HOE140 on rat tail artery, suggesting a synergistic inhibition mechanism by which targeting B2 type receptors. PMID- 27690100 TI - Structure, Evolution, and Functions of Bacterial Type III Toxin-Antitoxin Systems. AB - Toxin-antitoxin (TA) systems are small genetic modules that encode a toxin (that targets an essential cellular process) and an antitoxin that neutralises or suppresses the deleterious effect of the toxin. Based on the molecular nature of the toxin and antitoxin components, TA systems are categorised into different types. Type III TA systems, the focus of this review, are composed of a toxic endoribonuclease neutralised by a non-coding RNA antitoxin in a pseudoknotted configuration. Bioinformatic analysis shows that the Type III systems can be classified into subtypes. These TA systems were originally discovered through a phage resistance phenotype arising due to a process akin to an altruistic suicide; the phenomenon of abortive infection. Some Type III TA systems are bifunctional and can stabilise plasmids during vegetative growth and sporulation. Features particular to Type III systems are explored here, emphasising some of the characteristics of the RNA antitoxin and how these may affect the co evolutionary relationship between toxins and cognate antitoxins in their quaternary structures. Finally, an updated analysis of the distribution and diversity of these systems are presented and discussed. PMID- 27690101 TI - Effects of Citric and Lactic Acid on the Reduction of Deoxynivalenol and Its Derivatives in Feeds. AB - Exposure to mycotoxin-contaminated feeds represents a serious health risk. This has necessitated the need for the establishment of practical methods for mycotoxin decontamination. This study investigated the effects of citric acid (CA) and lactic acid (LA) on common trichothecene mycotoxins in feeds contaminated with Fusarium mycotoxins. Contaminated feed samples were processed either with 5% CA or 5% LA solutions in a ratio of 1:1.2 (w/v) for 5, 24, or 48 h, and analyzed for multiple mycotoxin metabolites using a liquid chromatography tandem mass spectrometric method. The analyses showed that treating the feed with CA and LA lowered the concentration of deoxynivalenol (DON), whereby 5% LA lowered the original DON concentration in the contaminated feed samples by half, irrespective of the processing time. Similar lowering effects were observed for the concentrations of 15Ac-DON, 5-hydroxyculmorin, and sambucinol. The concentration of nivalenol was only lowered by the LA treatment. In contrast, CA and LA treatments showed no or only small effects on the concentration of several mycotoxins and their derivatives, including zearalenone, fumonisins, and culmorin. In conclusion, the present results indicate that the use of 5% solutions of LA and CA might reduce the concentration of common trichothecene mycotoxins, especially DON and its derivate 15Ac-DON. However, further research is required to determine the effect on overall toxicity and to identify the underlying mechanisms. PMID- 27690103 TI - Transcript Abundance of Photorhabdus Insect-Related (Pir) Toxin in Manduca sexta and Galleria mellonella Infections. AB - In this study, we assessed pirAB toxin transcription in Photorhabdus luminescens laumondii (strain TT01) (Enterobacteriaceae) by comparing mRNA abundance under in vivo and in vitro conditions. In vivo assays considered both natural and forced infections with two lepidopteran hosts: Galleria mellonella and Manduca sexta. Three portals of entry were utilized for the forced infection assays: (a) integument; (b) the digestive route (via mouth and anus); and (c) the tracheal route (via spiracles). We also assessed plu4093-2 transcription during the course of a natural infection; this is when the bacteria are delivered by Heterorhabditis bacteriophora nematodes. Transcript abundance in G. mellonella was higher than in M. sexta at two of the observed time points: 15 and 18 h. Expression of pirAB plu4093-2 reached above endogenous control levels at 22 h in G. mellonella but not in M. sexta. Overall, pirAB plu4093-2 transcripts were not as highly expressed in M. sexta as in G. mellonella, from 15 to 22 h. This is the first study to directly compare pirAB plu4093-2 toxin transcript production considering different portals of entry. PMID- 27690104 TI - Translating into Practice Cancer Patients' Views on Do-Not-Resuscitate Decision Making. AB - Do-not-resuscitate (DNR) orders are necessary if resuscitation, the default option in hospitals, should be avoided because a patient is known to be dying and attempted resuscitation would be inappropriate. To avoid inappropriate resuscitation at night, if no DNR order has been recorded, after-hours medical staff are often asked to have a DNR discussion with patients whose condition is deteriorating, but with whom they are unfamiliar. Participants in two qualitative studies of cancer patients' views on how to present DNR discussions recognized that such patients are at different stages of understanding of their situation and may not be ready for a DNR discussion; therefore, a one-policy-fits-all approach was thought to be inappropriate. To formulate a policy that incorporates the patient's views, we propose that a standard form which mandates a DNR discussion is replaced by a "blank sheet" with instructions to record the progress of the discussion with the patient, and a medical recommendation for a DNR decision to guide the nursing staff in case of a cardiac arrest. Such an advance care directive would have to honor specifically expressed patient or guardian wishes whilst allowing for flexibility, yet would direct nurses or other staff so that they can avoid inappropriate cardiopulmonary resuscitation of a patient dying of cancer. PMID- 27690105 TI - Decreased Expression of KIFC1 in Human Testes with Globozoospermic Defects. AB - Globozoospermia is a rare (prevalence of <0.1%) but severe male infertility condition. In our previous study, we found that robust KIFC1 immunostaining was detected in the human elongating/elongated spermatids during human acrosomogenesis. However, the relationship between the decreased expression of KIFC1 and human globozoospermia remains largely unknown. Testicular biopsies of 30 globozoospermia and 30 obstructive azoospermia patients who underwent infertility evaluation and treatment were utilized in this study. Reverse transcriptase polymerase chain reaction (RT-PCR), Western blots, immunohistochemistry, an in vivo model, and intratesticular injection of small inhibitory RNA (siRNA) against the Kifc1 gene were employed, and sperm abnormalities were evaluated by hematoxylin and eosin (H&E) staining and immunocytochemistry. We revealed that the testicular level of KIFC1 mRNA in globozoospermia was significantly reduced compared with that in obstructive azoospermia, and the KIFC1 protein was barely detectable in testicular specimens in 30% (9 of 30) of patients with globozoospermia. Furthermore, knockdown of the Kifc1 gene in mice increased the percentage of sperm with globozoospermic defects (26.5%). Decreased KIFC1 expression was mainly observed in the testes of patients with globozoospermia at the spermatid stage, which may be useful for counseling and management of such patients. PMID- 27690102 TI - Metalloproteases Affecting Blood Coagulation, Fibrinolysis and Platelet Aggregation from Snake Venoms: Definition and Nomenclature of Interaction Sites. AB - Snake venom metalloproteases, in addition to their contribution to the digestion of the prey, affect various physiological functions by cleaving specific proteins. They exhibit their activities through activation of zymogens of coagulation factors, and precursors of integrins or receptors. Based on their structure-function relationships and mechanism of action, we have defined classification and nomenclature of functional sites of proteases. These metalloproteases are useful as research tools and in diagnosis and treatment of various thrombotic and hemostatic conditions. They also contribute to our understanding of molecular details in the activation of specific factors involved in coagulation, platelet aggregation and matrix biology. This review provides a ready reference for metalloproteases that interfere in blood coagulation, fibrinolysis and platelet aggregation. PMID- 27690106 TI - Impact of the Autism-Associated Long Noncoding RNA MSNP1AS on Neuronal Architecture and Gene Expression in Human Neural Progenitor Cells. AB - We previously identified the long noncoding RNA (lncRNA) MSNP1AS (moesin pseudogene 1, antisense) as a functional element revealed by genome wide significant association with autism spectrum disorder (ASD). MSNP1AS expression was increased in the postmortem cerebral cortex of individuals with ASD and particularly in individuals with the ASD-associated genetic markers on chromosome 5p14.1. Here, we mimicked the overexpression of MSNP1AS observed in postmortem ASD cerebral cortex in human neural progenitor cell lines to determine the impact on neurite complexity and gene expression. ReNcell CX and SK-N-SH were transfected with an overexpression vector containing full-length MSNP1AS. Neuronal complexity was determined by the number and length of neuronal processes. Gene expression was determined by strand-specific RNA sequencing. MSNP1AS overexpression decreased neurite number and neurite length in both human neural progenitor cell lines. RNA sequencing revealed changes in gene expression in proteins involved in two biological processes: protein synthesis and chromatin remodeling. These data indicate that overexpression of the ASD-associated lncRNA MSNP1AS alters the number and length of neuronal processes. The mechanisms by which MSNP1AS overexpression impacts neuronal differentiation may involve protein synthesis and chromatin structure. These same biological processes are also implicated by rare mutations associated with ASD, suggesting convergent mechanisms. PMID- 27690108 TI - Cloning and Expression Analysis of MEP Pathway Enzyme-encoding Genes in Osmanthus fragrans. AB - The 2-C-methyl-d-erythritol 4-phosphate (MEP) pathway is responsible for the biosynthesis of many crucial secondary metabolites, such as carotenoids, monoterpenes, plastoquinone, and tocopherols. In this study, we isolated and identified 10 MEP pathway genes in the important aromatic plant sweet osmanthus (Osmanthus fragrans). Multiple sequence alignments revealed that 10 MEP pathway genes shared high identities with other reported proteins. The genes showed distinctive expression profiles in various tissues, or at different flower stages and diel time points. The qRT-PCR results demonstrated that these genes were highly expressed in inflorescences, which suggested a tissue-specific transcript pattern. Our results also showed that OfDXS1, OfDXS2, and OfHDR1 had a clear diurnal oscillation pattern. The isolation and expression analysis provides a strong foundation for further research on the MEP pathway involved in gene function and molecular evolution, and improves our understanding of the molecular mechanism underlying this pathway in plants. PMID- 27690107 TI - Modeling Fragile X Syndrome Using Human Pluripotent Stem Cells. AB - Fragile X syndrome (FXS) is the most common heritable form of cognitive impairment. It results from a loss-of-function mutation by a CGG repeat expansion at the 5' untranslated region of the X-linked fragile X mental retardation 1 (FMR1) gene. Expansion of the CGG repeats beyond 200 copies results in protein deficiency by leading to aberrant methylation of the FMR1 promoter and the switch from active to repressive histone modifications. Additionally, the CGGs become increasingly unstable, resulting in high degree of variation in expansion size between and within tissues of affected individuals. It is still unclear how the FMR1 protein (FMRP) deficiency leads to disease pathology in neurons. Nor do we know the mechanisms by which the CGG expansion results in aberrant DNA methylation, or becomes unstable in somatic cells of patients, at least in part due to the lack of appropriate animal or cellular models. This review summarizes the current contribution of pluripotent stem cells, mutant human embryonic stem cells, and patient-derived induced pluripotent stem cells to disease modeling of FXS for basic and applied research, including the development of new therapeutic approaches. PMID- 27690109 TI - Metabolic Genes within Cyanophage Genomes: Implications for Diversity and Evolution. AB - Cyanophages, a group of viruses specifically infecting cyanobacteria, are genetically diverse and extensively abundant in water environments. As a result of selective pressure, cyanophages often acquire a range of metabolic genes from host genomes. The host-derived genes make a significant contribution to the ecological success of cyanophages. In this review, we summarize the host-derived metabolic genes, as well as their origin and roles in cyanophage evolution and important host metabolic pathways, such as the light-dependent reactions of photosynthesis, the pentose phosphate pathway, nutrient acquisition and nucleotide biosynthesis. We also discuss the suitability of the host-derived metabolic genes as potential diagnostic markers for the detection of genetic diversity of cyanophages in natural environments. PMID- 27690111 TI - Prey-Mediated Effects of Drought on the Consumption Rates of Coccinellid Predators of Elatobium abietinum. AB - Climate change in the UK is predicted to cause an increase in summer drought events. Elatobium abietinum is an important pest of Sitka spruce (Picea sitchensis), causing defoliation of trees, and is predicted to become more abundant in response to climatic change, reducing spruce productivity. Populations are also moderated by invertebrate predators, though the extent to which this might be modified under a changing climate is unclear. Elatobium abietinum is preyed upon by the coccinellid species Aphidecta obliterata (a spruce specialist) and Adalia bipunctata (a generalist), populations of which naturally occur in spruce plantations. This study sought to investigate the effect of different intensities and frequencies of drought on the consumption rate of the aphids by the two coccinellids. In Petri dish trials, severe drought stress increased the consumption rates of 3rd instar aphids by both adult and larval coccinellids. Moderate intermittent stress tended to result in a reduced consumption rate for larval coccinellids only, suggesting an age-dependent response. The findings of this study suggest that, under drought conditions, a prey-mediated effect on predator consumption, and, therefore, biocontrol efficacy, is likely, with drought intensity and frequency playing an important role in determining the nature of the response. PMID- 27690110 TI - Genome-Wide Identification, Characterization and Expression Profiling of ADF Family Genes in Solanum lycopersicum L. AB - The actin depolymerizing factor (ADF) proteins have growth, development, defense related and growth regulatory functions in plants. The present study used genome wide analysis to investigate ADF family genes in tomato. Eleven tomato ADF genes were identified and differential expression patterns were found in different organs. SlADF6 was preferentially expressed in roots, suggesting its function in root development. SlADF1, SlADF3 and SlADF10 were predominately expressed in the flowers compared to the other organs and specifically in the stamen compared to other flower parts, indicating their potential roles in pollen development. The comparatively higher expression of SlADF3 and SlADF11 at early fruit developmental stages might implicate them in determining final fruit size. SlADF5 and SlADF8 had relatively higher levels of expression five days after the breaker stage of fruit development, suggesting their possible role in fruit ripening. Notably, six genes were induced by cold and heat, seven by drought, five by NaCl, and four each by abscisic acid (ABA), jasmonic acid (JA) and wounding treatments. The differential expression patterns of the SlADF genes under different types of stresses suggested their function in stress tolerance in tomato plants. Our results will be helpful for the functional characterization of ADF genes during organ and fruit development of tomato under different stresses. PMID- 27690112 TI - Research Contributing to Improvements in Controlling Florida's Mosquitoes and Mosquito-borne Diseases. AB - Research on mosquitoes and mosquito-borne diseases has contributed to improvements in providing effective, efficient, and environmentally proper mosquito control. Florida has benefitted from several research accomplishments that have increased the state's mosquito control capabilities. Research with Florida's mosquitoes has resulted in the development of ecologically sound management of mosquito impoundments on Florida's east coast. This strategy, called Rotational Impoundment Management (RIM), has improved the ability to target the delivery of pesticides and has helped to reduce non-target effects and environmental damage. Research has led to the development of an arbovirus surveillance system which includes sentinel chicken surveillance, real time use of environmental contributing factors like meteorology and hydrology to target mosquito control, as well as public health efforts to mitigate disease outbreaks to areas with risk of disease. These research driven improvements have provided substantial benefits to all of Florida. More research is needed to meet the future challenges to reduce emerging pathogens like Zika virus and the consequences of environmental changes like global climate change that are likely to influence the effects of mosquito-borne pathogens on human health and well being. PMID- 27690113 TI - Periodic Physical Disturbance: An Alternative Method for Controlling Sitophilus zeamais (Maize Weevil) Infestation. AB - Sitophilus zeamais Motschulsky is the most important insect pest of stored maize in tropical regions. The objective of this study was to determine the practicality of periodic physical disturbance on S. zeamais mortality and its adoption by smallholder farmers in developing countries. In this experiment, treatments and control were arranged in a randomized block design with three replications and three storage times in three regions of Tanzania. Region was used as the blocking variable. A total of 108 clean 20-L plastic containers were each loaded with 10 kg of fresh white dent corn and 0.50 kg of maize infested with S. zeamais. For the treatment, containers were disturbed twice a day, whereas for the controls the containers were not disturbed until the end of storage. The overall mortality rate (%) after 30, 60, and 90 days of storage were 88%, 96%, and 98%, respectively. A statistically significant difference (p < 0.05) was observed for the number of live S. zeamais between the control and experimental treatments. Additionally, the number of live S. zeamais in the treatment significantly decreased as storage time increased. This study shows the potential of a feasible, simple, affordable, and effective method of protecting maize grain for small-holder farmers in developing countries without using chemicals. PMID- 27690114 TI - Long-Term Engagement in Formal Volunteering and Well-Being: An Exploratory Indian Study. AB - Sustained engagement in volunteering and its correlates have been examined in many studies across the globe. However, there is a dearth of research that explores the perspectives of long-term formal volunteers on the nature of changes perceived in oneself as a result of volunteering. Moreover, the linkages between psychological well-being and volunteering have been insufficiently explored. The present study was aimed at addressing these gaps. A heterogeneous sample of 20 long-term formal volunteer engaged in volunteering across different voluntary organisations in a southern metropolitan Indian city formed the primary sample for the study. In addition, a group of 21 short-term volunteers, matched on age, income and gender, was utilised for comparison with long-term volunteers on well being indices. A semi structured interview schedule was used to explore self perceived changes attributable to volunteering experience. In addition, a few standardised measures were used to comprehensively assess subjective well-being and psychological well-being. The interview data provided rich descriptions of perceived positive changes in self across cognitive, behavioral and emotional domains. Mirroring these patterns, the quantitative analyses indicated that long term volunteers experienced higher levels of psychological well-being (sense of mastery and competence, self-acceptance and sense of engagement and growth) than short-term volunteers. The potential mechanisms involved in beneficial outcomes of long-term volunteering and implications for further research are highlighted. PMID- 27690115 TI - Morphology of Donor and Recipient Nerves Utilised in Nerve Transfers to Restore Upper Limb Function in Cervical Spinal Cord Injury. AB - Loss of hand function after cervical spinal cord injury (SCI) impacts heavily on independence. Multiple nerve transfer surgery has been applied successfully after cervical SCI to restore critical arm and hand functions, and the outcome depends on nerve integrity. Nerve integrity is assessed indirectly using muscle strength testing and intramuscular electromyography, but these measures cannot show the manifestation that SCI has on the peripheral nerves. We directly assessed the morphology of nerves biopsied at the time of surgery, from three patients within 18 months post injury. Our objective was to document their morphologic features. Donor nerves included teres minor, posterior axillary, brachialis, extensor carpi radialis brevis and supinator. Recipient nerves included triceps, posterior interosseus (PIN) and anterior interosseus nerves (AIN). They were fixed in glutaraldehyde, processed and embedded in Araldite Epon for light microscopy. Eighty percent of nerves showed abnormalities. Most common were myelin thickening and folding, demyelination, inflammation and a reduction of large myelinated axon density. Others were a thickened perineurium, oedematous endoneurium and Renaut bodies. Significantly, very thinly myelinated axons and groups of unmyelinated axons were observed indicating regenerative efforts. Abnormalities exist in both donor and recipient nerves and they differ in appearance and aetiology. The abnormalities observed may be preventable or reversible. PMID- 27690116 TI - Prenatal Ethanol Exposure and Whisker Clipping Disrupt Ultrasonic Vocalizations and Play Behavior in Adolescent Rats. AB - Prenatal ethanol exposure can result in social deficits in humans and animals, including altered social interaction and poor communication. Rats exposed to ethanol prenatally show reduced play fighting, and a combination of prenatal ethanol exposure and neonatal whisker clipping further reduces play fighting compared with ethanol exposure alone. In this study, we explored whether expression of hedonic ultrasonic vocalizations (USVs) correlated with the number of playful attacks by ethanol-exposed rats, rats subjected to postnatal sensory deprivation by whisker clipping or both compared to control animals. In normally developing rats, hedonic USVs precede such interactions and correlate with the number of play interactions exhibited in dyads. Pregnant Long-Evans rats were fed an ethanol-containing liquid diet or a control diet. After birth, male and female pups from each litter were randomly assigned to the whisker-clipped or non whisker-clipped condition. Animals underwent a social interaction test with a normally developing play partner during early or late-adolescence. USVs were recorded during play. Prenatal ethanol exposure reduced both play and hedonic USVs in early adolescence compared to control rats and persistently reduced social play. Interestingly, ethanol exposure, whisker clipping and the combination abolished the significant correlation between hedonic USVs and social play detected in control rats in early adolescence. This relationship remained disrupted in late adolescence only in rats subjected to both prenatal ethanol and whisker clipping. Thus, both insults more persistently disrupted the relationship between social communication and social play. PMID- 27690117 TI - Effect of Experimental Cutaneous Hand Pain on Corticospinal Excitability and Short Afferent Inhibition. AB - Sensorimotor integration is altered in people with chronic pain. While there is substantial evidence that pain interferes with neural activity in primary sensory and motor cortices, much less is known about its impact on integrative sensorimotor processes. Here, the short latency afferent inhibition (SAI) paradigm was used to assess sensorimotor integration in the presence and absence of experimental cutaneous heat pain applied to the hand. Ulnar nerve stimulation was combined with transcranial magnetic stimulation to condition motor evoked potentials (MEPs) in the first dorsal interosseous muscle. Four interstimulus intervals (ISI) were tested, based on the latency of the N20 component of the afferent sensory volley (N20-5 ms, N20+2 ms, N20+4 ms, N20+10 ms). In the PAIN condition, MEPs were smaller compared to the NEUTRAL condition (p = 0.005), and were modulated as a function of the ISI (p = 0.012). Post-hoc planned comparisons revealed that MEPs at N20+2 and N20+4 were inhibited compared to unconditioned MEPs. However, the level of inhibition (SAI) was similar in the PAIN and NEUTRAL conditions. This suggests that the interplay between pain and sensorimotor integration is not mediated through direct and rapid pathways as assessed by SAI, but rather might involve higher-order integrative areas. PMID- 27690119 TI - Biosensing with Paper-Based Miniaturized Printed Electrodes-A Modern Trend. AB - From the bench-mark work on microfluidics from the Whitesides's group in 2007, paper technology has experienced significant growth, particularly regarding applications in biomedical research and clinical diagnostics. Besides the structural properties supporting microfluidics, other advantageous features of paper materials, including their versatility, disposability and low cost, show off the great potential for the development of advanced and eco-friendly analytical tools. Consequently, paper was quickly employed in the field of electrochemical sensors, being an ideal material for producing custom, tailored and miniaturized devices. Stencil-, inkjet-, or screen-printing are the preferential techniques for electrode manufacturing. Not surprisingly, we witnessed a rapid increase in the number of publications on paper based screen printed sensors at the turn of the past decade. Among the sensing strategies, various biosensors, coupling electrochemical detectors with biomolecules, have been proposed. This work provides a critical review and a discussion on the future progress of paper technology in the context of miniaturized printed electrochemical biosensors. PMID- 27690118 TI - Recent Advances in the Fabrication and Application of Screen-Printed Electrochemical (Bio)Sensors Based on Carbon Materials for Biomedical, Agri-Food and Environmental Analyses. AB - This review describes recent advances in the fabrication of electrochemical (bio)sensors based on screen-printing technology involving carbon materials and their application in biomedical, agri-food and environmental analyses. It will focus on the various strategies employed in the fabrication of screen-printed (bio)sensors, together with their performance characteristics; the application of these devices for the measurement of selected naturally occurring biomolecules, environmental pollutants and toxins will be discussed. PMID- 27690120 TI - Discrepancy in Vancomycin AUC/MIC Ratio Targeted Attainment Based upon the Susceptibility Testing in Staphylococcus aureus. AB - This study demonstrated a statistically significant difference in vancomycin minimum inhibitory concentration (MIC) for Staphylococcus aureus between a common automated system (Vitek 2) and the E-test method in patients with S. aureus bloodstream infections. At an area under the serum concentration time curve (AUC) threshold of 400 mg?h/L, we would have reached the current Infectious Diseases Society of America (IDSA)/American Society of Health System Pharmacists (ASHP)/Society of Infectious Diseases Pharmacists (SIDP) guideline suggested AUC/MIC target in almost 100% of patients while using the Vitek 2 MIC data; however, we could only generate 40% target attainment while using E-test MIC data (p < 0.0001). An AUC of 450 mg?h/L or greater was required to achieve 100% target attainment using either Vitek 2 or E-test MIC results. PMID- 27690121 TI - Resistance to beta-Lactams in Neisseria ssp Due to Chromosomally Encoded Penicillin-Binding Proteins. AB - Neisseria meningitidis and Neisseria gonorrhoeae are human pathogens that cause a variety of life-threatening systemic and local infections, such as meningitis or gonorrhoea. The treatment of such infection is becoming more difficult due to antibiotic resistance. The focus of this review is on the mechanism of reduced susceptibility to penicillin and other beta-lactams due to the modification of chromosomally encoded penicillin-binding proteins (PBP), in particular PBP2 encoded by the penA gene. The variety of penA alleles and resulting variant PBP2 enzymes is described and the important amino acid substitutions are presented and discussed in a structural context. PMID- 27690122 TI - Effectiveness of a Lifestyle Intervention in Patients with Type 2 Diabetes: The Physical Activity and Nutrition for Diabetes in Alberta (PANDA) Trial. AB - Type 2 diabetes (T2D) patients often find integrating a new dietary pattern into their lifestyle challenging; therefore, the PANDA (Physical Activity and Nutrition for Diabetes in Alberta) menu plan intervention was developed to help people incorporate the Canadian Diabetes Association (CDA) nutrition therapy guidelines into their daily lives. The menu plan focused on recipes and foods that were accessible, available and acceptable to Albertans. The objective was to evaluate the effectiveness of the intervention on blood glucose control and dietary adherence and quality among patients with T2D. Participants with T2D (n = 73) enrolled in a single-arm incorporating interactive education based on a four week menu plan that incorporated the recommendations of the CDA nutrition therapy guidelines. Post-intervention follow-up was conducted at three and six months. After three months, there were beneficial changes in A1c (-0.7%), body mass index (BMI, -0.6 kg/m2), diastolic blood pressure (-4 mmHg), total cholesterol (-63 mg/dL), HDL- (+28 mg/dL) and LDL-cholesterol (-89 mg/dL), Healthy Eating Index (+2.1 score) and perceived dietary adherence (+8.5 score) (all p < 0.05). The significant improvements in A1c, BMI and lipids were maintained at six months. The PANDA menu plan intervention was effective in improving glycemic control and diet quality. The results suggest that a dietary intervention incorporating interactive education sessions focused on menu planning with familiar, accessible foods may be effective for diabetes management. PMID- 27690123 TI - The role of Polycomb in stem cell genome architecture. AB - Polycomb-group proteins maintain embryonic stem cell identity by repressing genes that encode for developmental regulatory factors. Failure to properly control developmental transcription programs by Polycomb proteins is linked to disease and embryonic lethality. Recent technological advances have revealed that developmentally repressed genes tend to cluster in the three-dimensional space of the nucleus. Importantly, spatial clustering of developmental genes is fundamental for the correct regulation of gene expression during early development. Here, we outline novel insights and perspectives regarding the function of Polycomb complexes in shaping the stem cell genome architecture, and discuss how this function might be required to properly orchestrate transcriptional programs during differentiation. PMID- 27690124 TI - Effects of acoustic periodicity, intelligibility, and pre-stimulus alpha power on the event-related potentials in response to speech. AB - Magneto- and electroencephalographic (M/EEG) signals in response to acoustically degraded speech have been examined by several recent studies. Unambiguously interpreting the results is complicated by the fact that speech signal manipulations affect acoustics and intelligibility alike. In the current EEG study, the acoustic properties of the stimuli were altered and the trials were sorted according to the correctness of the listeners' spoken responses to separate out these two factors. Firstly, more periodicity (i.e. voicing) rendered the event-related potentials (ERPs) more negative during the first second after sentence onset, indicating a greater cortical sensitivity to auditory input with a pitch. Secondly, we observed a larger contingent negative variation (CNV) during sentence presentation when the subjects could subsequently repeat more words correctly. Additionally, slow alpha power (7-10Hz) before sentences with the least correctly repeated words was increased, which may indicate that subjects have not been focussed on the upcoming task. PMID- 27690125 TI - Bilateral parietal contributions to spatial language. AB - It is commonly held that language is largely lateralized to the left hemisphere in most individuals, whereas spatial processing is associated with right hemisphere regions. In recent years, a number of neuroimaging studies have yielded conflicting results regarding the role of language and spatial processing areas in processing language about space (e.g., Carpenter, Just, Keller, Eddy, & Thulborn, 1999; Damasio et al., 2001). In the present study, we used sparse scanning event-related functional magnetic resonance imaging (fMRI) to investigate the neural correlates of spatial language, that is; language used to communicate the spatial relationship of one object to another. During scanning, participants listened to sentences about object relationships that were either spatial or non-spatial in nature (color or size relationships). Sentences describing spatial relationships elicited more activation in the superior parietal lobule and precuneus bilaterally in comparison to sentences describing size or color relationships. Activation of the precuneus suggests that spatial sentences elicit spatial-mental imagery, while the activation of the SPL suggests sentences containing spatial language involve integration of two distinct sets of information - linguistic and spatial. PMID- 27690126 TI - Urine Bacterial Community Convergence through Fertilizer Production: Storage, Pasteurization, and Struvite Precipitation. AB - Source-separated human urine was collected from six public events to study the impact of urine processing and storage on bacterial community composition and viability. Illumina 16S rRNA gene sequencing revealed a complex community of bacteria in fresh urine that differed across collection events. Despite the harsh chemical conditions of stored urine (pH > 9 and total ammonia nitrogen > 4000 mg N/L), bacteria consistently grew to 5 +/- 2 * 108 cells/mL. Storing hydrolyzed urine for any amount of time significantly reduced the number of operational taxonomic units (OTUs) to 130 +/- 70, increased Pielou evenness to 0.60 +/- 0.06, and produced communities dominated by Clostridiales and Lactobacillales. After 80 days of storage, all six urine samples from different starting materials converged to these characteristics. Urine pasteurization or struvite precipitation did not change the microbial community, even when pasteurized urine was stored for an additional 70 days. Pasteurization decreased metabolic activity by 50 +/- 10% and additional storage after pasteurization did not lead to recovery of metabolic activity. Urine-derived fertilizers consistently contained 16S rRNA genes belonging to Tissierella, Erysipelothrix, Atopostipes, Bacteroides, and many Clostridiales OTUs; additional experiments must determine whether pathogenic species are present, responsible for observed metabolic activity, or regrow when applied. PMID- 27690127 TI - Depletion of Neutrophils Promotes the Resolution of Pulmonary Inflammation and Fibrosis in Mice Infected with Paracoccidioides brasiliensis. AB - Chronic stages of paracoccidioidomycosis (PCM) are characterized by granulomatous lesions which promote the development of pulmonary fibrosis leading to the loss of respiratory function in 50% of patients; in addition, it has been observed that neutrophils predominate during these chronic stages of P. brasiliensis infection. The goal of this study was to evaluate the role of the neutrophil during the chronic stages of experimental pulmonary PCM and during the fibrosis development and tissue repair using a monoclonal specific to this phagocytic cell. Male BALB/c mice were inoculated intranasally with 1.5x106 P. brasiliensis yeast cells. A monoclonal antibody specific to neutrophils was administered at 4 weeks post-inoculation followed by doses every 48h during two weeks. Mice were sacrificed at 8 and 12 weeks post-inoculation to assess cellularity, fungal load, cytokine/chemokine levels, histopathological analysis, collagen and expression of genes related to fibrosis development. Depletion of neutrophils was associated with a significant decrease in the number of eosinophils, dendritic cells, B cells, CD4-T cells, MDSCs and Treg cells, fungal load and levels of most of the pro-inflammatory cytokines/chemokines evaluated, including IL-17, TNF-alpha and TGF-beta1. Recovery of lung architecture was also associated with reduced levels of collagen, high expression of TGF-beta3, matrix metalloproteinase (MMP)-12 and 14, and decreased expression of tissue inhibitor metalloproteinase (TIMP)-2, and MMP-8. Depletion of neutrophils might attenuate lung fibrosis and inflammation through down-regulating TGF-beta1, TNF-alpha, IL-17, MMP-8 and TIMP-2. These results suggest that neutrophil could be considered as a therapeutic target in pulmonary fibrosis induced by P. brasiliensis. PMID- 27690128 TI - Characterization of a Thermoresponsive Chitosan Derivative as a Potential Draw Solute for Forward Osmosis. AB - A thermoresponsive chitosan derivative was synthesized by reacting chitosan (CS) with butyl glycidyl ether (BGE) to break the inter- and intramolecular hydrogen bonds of the polymer. An aqueous solution of the thermoresponsive CS derivative exhibits a lower critical solution temperature (LCST) than CS, and it undergoes a phase transition separation when the temperature changes. Successful incorporation of BGE into the CS was confirmed by FTIR and XPS analyses. Varying the BGE content and the concentration of the aqueous solution produced different LCST ranges, as shown by transmittance vs temperature curves. The particle size was observed by scanning electron microscopy, which revealed that the particles were smaller and well dispersed at 15 degrees C, whereas the particles became larger and tended to aggregate at 60 degrees C. A similar trend was observed with the mean particle size measured using dynamic light scattering. Positron annihilation lifetime spectroscopy data also revealed the reversibility of the particle properties as a function of temperature. Microstructure analysis showed that the particles had larger free-volume sizes at 15 degrees C than at 60 degrees C. The particles were also found to be nontoxic with 92% cell survival. A simple forward osmosis (FO) test for dye dehydration revealed the potential use of the thermoresponsive chitosan derivative as a draw solute with a flux of 8.6 L/m2 h and rejection of 99.8%. PMID- 27690130 TI - Identification and Characterization of Two Human Monocyte-Derived Dendritic Cell Subpopulations with Different Functions in Dying Cell Clearance and Different Patterns of Cell Death. AB - Human monocyte-derived dendritic cells (mdDCs) are versatile cells that are used widely for research and experimental therapies. Although different culture conditions can affect their characteristics, there are no known subpopulations. Since monocytes differentiate into dendritic cells (DCs) in a variety of tissues and contexts, we asked whether they can give rise to different subpopulations. In this work we set out to characterize two human mdDC subpopulations that we identified and termed small (DC-S) and large (DC-L). Morphologically, DC-L are larger, more granular and have a more complex cell membrane. Phenotypically, DC-L show higher expression of a wide panel of surface molecules and stronger responses to maturation stimuli. Transcriptomic analysis confirmed their separate identities and findings were consistent with the phenotypes observed. Although they show similar apoptotic cell uptake, DC-L have different capabilities for phagocytosis, demonstrate better antigen processing, and have significantly better necrotic cell uptake. These subpopulations also have different patterns of cell death, with DC-L presenting an inflammatory, "dangerous" phenotype while DC S mostly downregulate their surface markers upon cell death. Apoptotic cells induce an immune-suppressed phenotype, which becomes more pronounced among DC-L, especially after the addition of lipopolysaccharide. We propose that these two subpopulations correspond to inflammatory (DC-L) and steady-state (DC-S) DC classes that have been previously described in mice and humans.

AB - Critical to the design and assessment of interventions for enteropathy and its developmental consequences in children living in impoverished conditions are non invasive biomarkers that can detect intestinal damage and predict its effects on growth and development. We therefore assessed fecal, urinary and systemic biomarkers of enteropathy and growth predictors in 375 6-26 month-old children with varying degrees of malnutrition (stunting or wasting) in Northeast Brazil. 301 of these children returned for followup anthropometry after 2-6m. Biomarkers that correlated with stunting included plasma IgA anti-LPS and anti-FliC, zonulin (if >12m old), and intestinal FABP (I-FABP, suggesting prior barrier disruption); and with citrulline, tryptophan and with lower serum amyloid A (SAA) (suggesting impaired defenses). In contrast, subsequent growth was predicted in those with higher fecal MPO or A1AT and also by higher L/M, plasma LPS, I-FABP and SAA (showing intestinal barrier disruption and inflammation). Better growth was predicted in girls with higher plasma citrulline and in boys with higher plasma tryptophan. Interactions were also seen with fecal MPO and neopterin in predicting subsequent growth impairment. Biomarkers clustered into markers of 1) functional intestinal barrier disruption and translocation, 2) structural intestinal barrier disruption and inflammation and 3) systemic inflammation. Principle components pathway analyses also showed that L/M with %L, I-FABP and MPO associate with impaired growth, while also (like MPO) associating with a systemic inflammation cluster of kynurenine, LBP, sCD14, SAA and K/T. Systemic evidence of LPS translocation associated with stunting, while markers of barrier disruption or repair (A1AT and Reg1 with low zonulin) associated with fecal MPO and neopterin. We conclude that key noninvasive biomarkers of intestinal barrier disruption, LPS translocation and of intestinal and systemic inflammation can help elucidate how we recognize, understand, and assess effective interventions for enteropathy and its growth and developmental consequences in children in impoverished settings.

AB - The reporting of evaluation outcomes can be a point of contention between evaluators and policy-makers when a given reform fails to fulfil its promises. Whereas evaluators are required to report outcomes in full, policy-makers have a vested interest in framing these outcomes in a positive light-especially when they previously expressed a commitment to the reform. The current evidence base is limited to a survey of policy evaluators, a study on reporting bias in education research and several studies investigating the influence of industry sponsorship on the reporting of clinical trials. The objective of this study was twofold. Firstly, it aimed to assess the risk of outcome reporting bias (ORB or 'spin') in pilot evaluation reports, using seven indicators developed by clinicians. Secondly, it sought to examine how the government's commitment to a given reform may affect the level of ORB found in the corresponding evaluation report. To answer these questions, 13 evaluation reports were content-analysed, all of which found a non-significant effect of the intervention on its stated primary outcome. These reports were systematically selected from a dataset of 233 pilot and experimental evaluations spanning three policy areas and 13 years of government-commissioned research in the UK. The results show that the risk of ORB is real. Indeed, all studies reviewed here resorted to at least one of the presentational strategies associated with a risk of spin. This study also found a small, negative association between the seniority of the reform's champion and the risk of ORB in the evaluation of that reform. The publication of protocols and the use of reporting guidelines are recommended. PMID- 27690132 TI - Deficits in metaphor but not in idiomatic processing are related to verbal hallucinations in patients with psychosis. AB - There is scant evidence that the verbal cognitive deficits observed in patients with psychosis are related to auditory verbal hallucinations. The understanding of metaphors and idiomatic expressions was investigated in a cohort of 90 patients with active psychosis, and in 44 healthy controls. The Psychotic Symptom Rating Scales (PSYRATS: verbal hallucinations subscale) was used to measure the current verbal hallucinations episode; a subscore of the Launay-Slade Hallucination Scale was used to measure long-term propensity to auditory verbal hallucination-like experiences (HLEs) in the sample. The concurrent influence of education, IQ, and cognitive functioning in memory, attention, fluency, and processing speed on metaphor and idioms processing was investigated. Patients performed worse than healthy controls on all neuropsychological measures. Metaphor, but not idioms processing was poorer in patients with verbal hallucinations (n=46) when compared to patients without verbal hallucinations in the current episode (n=44). By taking into account confounding variables, the ability to produce explanations of metaphors was related to scores on the verbal HLEs in the whole sample of patients. Metaphor-comprehension deficit was related to the occurrence of auditory verbal hallucinations in patients with psychosis, suggesting that abnormal pragmatic inferential abilities have an impact on the mechanisms that cause hallucinatory experiences. PMID- 27690133 TI - Mediating and moderating effects of attentional control on the relationship between personality traits and attentional bias among Chinese medical students. AB - This study aimed to explore the mediating and moderating effects in the relationship between personality traits and attentional bias. A cross-sectional study was conducted among Chinese medical students. A total of 1047 Chinese medical students completed self-report measures of extraversion, neuroticism, attentional control, attention to positive information (API) and negative information (ANI). The data were analyzed with correlation, structural equation modeling, and multiple linear regression. The results revealed that attentional control mediated the effects of extraversion and neuroticism on attentional bias. Moreover, the association of neuroticism and ANI, and that of extraversion and API were both moderated by attentional control. These results extended our understanding of the relationship between extraversion, neuroticism, and attentional bias, by demonstrating that attentional control may serve as a protective factor for amplifying the positive emotional bias of extraverts and alleviating or eliminating the negative emotional bias of neurotics. PMID- 27690134 TI - Induced Obsessive Compulsive Symptoms (OCS) in schizophrenia patients under Atypical 2 Antipsychotics (AAPs): review and hypotheses. AB - The prevalence of OCS and OCD is higher in schizophrenic patients than in the general population. These disorders are sometimes induced by AAPs. There is higher frequency of OCS and greater severity in patients treated with antipsychotics with predominant anti-serotoninergic profiles opposed to those with predominant dopaminergic blockade. Induced OCS may be due to complex neuromodulation involving many serotonin, dopamine and glutamate receptors and several subtypes. Concerning connectivity, AAPs differentially influence the BOLD signal, depending on the intensity of D2 receptor blockade. The OFC could play a significant role, on account of its involvement in inhibitory control. There is a paradox: AAPs are efficient as augmentation to SSRI in treatment resistant OCD, some of them such as risperidone or aripiprazole have favourable effects in schizoptypic OCD, but AAPs cause induced OCS in schizophrenic patients. When prescribing AAPs, we should inform patients about this potential side effect and assess systematically OCS with Y-BOCS assessment after 1 month of treatment. Afterwards there are different strategies: Aripiprazole in combination can reduce OCS induced by clozapine, SSRI are slightly effective and CBT shows a few encouraging results. OCS are sometimes dose-dependent, so we also recommend prescribing the minimum effective dose and gradual introduction. PMID- 27690135 TI - Mutations in Nonessential eIF3k and eIF3l Genes Confer Lifespan Extension and Enhanced Resistance to ER Stress in Caenorhabditis elegans. AB - The translation initiation factor eIF3 is a multi-subunit protein complex that coordinates the assembly of the 43S pre-initiation complex in eukaryotes. Prior studies have demonstrated that not all subunits of eIF3 are essential for the initiation of translation, suggesting that some subunits may serve regulatory roles. Here, we show that loss-of-function mutations in the genes encoding the conserved eIF3k and eIF3l subunits of the translation initiation complex eIF3 result in a 40% extension in lifespan and enhanced resistance to endoplasmic reticulum (ER) stress in Caenorhabditis elegans. In contrast to previously described mutations in genes encoding translation initiation components that confer lifespan extension in C. elegans, loss-of-function mutations in eif-3.K or eif-3.L are viable, and mutants show normal rates of growth and development, and have wild-type levels of bulk protein synthesis. Lifespan extension resulting from EIF-3.K or EIF-3.L deficiency is suppressed by a mutation in the Forkhead family transcription factor DAF-16. Mutations in eif-3.K or eif-3.L also confer enhanced resistance to ER stress, independent of IRE-1-XBP-1, ATF-6, and PEK-1, and independent of DAF-16. Our data suggest a pivotal functional role for conserved eIF3k and eIF3l accessory subunits of eIF3 in the regulation of cellular and organismal responses to ER stress and aging. PMID- 27690137 TI - A cut above the rest? Private anthropometrics in marriage markets. AB - A large body of economic research suggests that publicly observable anthropometric characteristics affect labor and marriage market outcomes. Private anthropometrics may not affect these outcomes. We examine male circumcision in marriage markets in Zambia. Our analysis reveals substantial variation across local marriage markets in circumcision prevalence relative to preference for circumcised partners, as well as excess aggregate demand for circumcised males. Regression estimates suggest a marriage market premium of approximately one-half to one year of additional schooling for matching with a partner of preferred anthropometric type in a local marriage market with excess demand for that anthropometric characteristic.

AB - 3-Nitropropionic acid (3-NP) is an irreversible inhibitor of mitochondrial complex-II that causes transcriptional dysregulation, bioenergetics failure, protein aggregation and oxidative damage similar to Huntington's disease (HD) pathogenesis. Chrysin, a bioactive flavonoid reported to have anti-inflammation, antioxidant, vasorelaxant and neuroprotective property. The present study was framed to determine the neuroprotective efficiency of chrysin upon 3-NP induced oxidative stress, mitochondrial dysfunctions and neurodegeneration. 3-NP (10mg/kg b.w. i.p.) administration for 14days exhibited significant (P<0.01) behavioral alterations, mitochondrial dysfunction and oxidative damages to biomolecules, finally causes cell death. Chrysin at 50mg/kg b.w. orally for 14days improved all the behavioral performances and regulated the complex activities in mitochondria. Further, chrysin diminished the oxidative stress markers (lipid peroxidation, nitrite and protein carbonyls) by significantly (P<0.01) improving the antioxidant status (superoxide dismutase, catalase and reduced glutathione) in striatal mitochondria. Indeed, chrysin prevents apoptosis by upregulating the Bcl 2 mRNA expression and downregulating the pro-apoptotic (Bax, Bad) mRNAs in 3-NP induced condition. Furthermore, the survival of striatal neurons against 3-NP toxicity was enhanced upon chrysin treatment which was evidenced by observing histopathological studies. Hence, the present study collectively suggests that the chrysin can serve as a potential therapeutic agent on 3-NP induced mitochondrial deficits and subsequent apoptosis. PMID- 27690138 TI - Discriminative Analysis of Migraine without Aura: Using Functional and Structural MRI with a Multi-Feature Classification Approach. AB - Magnetic resonance imaging (MRI) is by nature a multi-modality technique that provides complementary information about different aspects of diseases. So far no attempts have been reported to assess the potential of multi-modal MRI in discriminating individuals with and without migraine, so in this study, we proposed a classification approach to examine whether or not the integration of multiple MRI features could improve the classification performance between migraine patients without aura (MWoA) and healthy controls. Twenty-one MWoA patients and 28 healthy controls participated in this study. Resting-state functional MRI data was acquired to derive three functional measures: the amplitude of low-frequency fluctuations, regional homogeneity and regional functional correlation strength; and structural MRI data was obtained to measure the regional gray matter volume. For each measure, the values of 116 pre-defined regions of interest were extracted as classification features. Features were first selected and combined by a multi-kernel strategy; then a support vector machine classifier was trained to distinguish the subjects at individual level. The performance of the classifier was evaluated using a leave-one-out cross validation method, and the final classification accuracy obtained was 83.67% (with a sensitivity of 92.86% and a specificity of 71.43%). The anterior cingulate cortex, prefrontal cortex, orbitofrontal cortex and the insula contributed the most discriminative features. In general, our proposed framework shows a promising classification capability for MWoA by integrating information from multiple MRI features. PMID- 27690139 TI - Trends in cigarette use, by serious psychological distress status in the United States, 1998-2013. AB - OBJECTIVES: The study compared trends in current and heavy cigarette smoking between adults with and without serious psychological distress (SPD). METHODS: This study examined data from 480,024 adults aged 18years or older in the 1998 2013 National Health Interview Survey (NHIS) public use files. SPD is defined as having a Kessler-6 score of 13 or higher in the past month. Trends in the prevalence of current smoking and heavy smoking for 2-year time periods were assessed among those with versus those without SPD using logistic regression; tests of interaction terms determined whether smoking trends differed by SPD status. RESULTS: The prevalence of current smoking decreased over time among adults without SPD (adjusted odds ratio [AOR]=0.97, 95% CI=0.97-0.98), but remained stable among adults with SPD (AOR=1.01, 95% CI=0.99-1.03). Both groups had significant declines in heavy smoking over time; however, the rates of decline were greater among adults without versus with SPD (AOR=0.87, 95% CI=0.86 0.88 and AOR=0.91, 95% CI=0.88-0.94, respectively). CONCLUSIONS: The prevalence of current smoking is not declining among adults with SPD, and the prevalence of heavy smoking is not declining as quickly among adults with SPD as compared with those without SPD. Smoking cessation efforts may need to target these populations and tailor programs accordingly. PMID- 27690140 TI - Performance of a real-time PCR-based approach and droplet digital PCR in detecting human parechovirus type 3 RNA. AB - BACKGROUND: Human parechovirus type 3 (HPeV3) is an emerging virus that causes sepsis and meningoencephalitis in neonates and young infants. Correct diagnosis of HPeV3 infection is critical in determining appropriate management and predicting patients' clinical course. Real-time reverse transcription PCR (RT PCR) analysis of serum and/or cerebrospinal fluid (CSF) has been used to diagnose HPeV3 infection; however, the assay detection limits have not been fully evaluated. OBJECTIVES: We tested the hypothesis that droplet digital RT-PCR (RT ddPCR)-a novel technique that precisely quantitates low-copy target genes by diluting and partitioning samples into compartments-increases the detection rate of HPeV3 RNA as compared with real-time RT-PCR. STUDY DESIGN: Using samples with predetermined HPeV3 copy numbers, we evaluated one-step and two-step RT-ddPCR. Then, we tested two-step RT-ddPCR and real-time RT-PCR, using clinical samples with low copy numbers. Finally, we used two-step RT-ddPCR to evaluate clinical samples obtained from HPeV3-infected patients with positive serum but negative CSF, as determined by real-time RT-PCR. RESULTS: Two-step RT-ddPCR was less variable and more specific than one-step RT-ddPCR. Two-step RT-ddPCR detected HPeV3 RNA in all six CSF samples; four samples (67%) were reproducibly positive and the other two samples (33%) were positive at least once in four replicates. Finally, no nonspecific droplet was positive by two-step RT-ddPCR. CONCLUSIONS: Two-step RT-ddPCR may enhance the rate of HPeV3 RNA detection from samples with low viral loads, thereby improving diagnosis and management of HPeV3-infected patients.

AB - Efficient and practical visible-light photoredox borylation of aryl halides and subsequent aerobic oxidative hydroxylation were developed. The protocols use readily available aryl halides and bis(pinacolato)diboron as the starting materials, fac-Ir(ppy)3 as the photocatalyst, and corresponding arylboronic esters and phenols were obtained in good yields. The methods show some advantages including simple equipment, mild conditions, easy operation, and wide substrate scope. Therefore, they should provide a valuable strategy for chemical transformations. PMID- 27690143 TI - Bioinspired Design of Polycaprolactone Composite Nanofibers as Artificial Bone Extracellular Matrix for Bone Regeneration Application. AB - The design and development of functional biomimetic systems for programmed stem cell response is a field of topical interest. To mimic bone extracellular matrix, we present an innovative strategy for constructing drug-loaded composite nanofibrous scaffolds in this study, which could integrate multiple cues from calcium phosphate mineral, bioactive molecule, and highly ordered fiber topography for the control of stem cell fate. Briefly, inspired by mussel adhesion mechanism, a polydopamine (pDA)-templated nanohydroxyapatite (tHA) was synthesized and then surface-functionalized with bone morphogenetic protein-7 derived peptides via catechol chemistry. Afterward, the resulting peptide-loaded tHA (tHA/pep) particles were blended with polycaprolactone (PCL) solution to fabricate electrospun hybrid nanofibers with random and aligned orientation. Our research demonstrated that the bioactivity of grafted peptides was retained in composite nanofibers. Compared to controls, PCL-tHA/pep composite nanofibers showed improved cytocompatibility. Moreover, the incorporated tHA/pep particles in nanofibers could further facilitate osteogenic differentiation potential of human mesenchymal stem cells (hMSCs). More importantly, the aligned PCL-tHA/pep composite nanofibers showed more osteogenic activity than did randomly oriented counterparts, even under nonosteoinductive conditions, indicating excellent performance of biomimetic design in cell fate decision. After in vivo implantation, the PCL-tHA/pep composite nanofibers with highly ordered structure could significantly promote the regeneration of lamellar-like bones in a rat calvarial critical-sized defect. Accordingly, the presented strategy in our work could be applied for a wide range of potential applications in not only bone regeneration application but also pharmaceutical science. PMID- 27690141 TI - Genetic characterization of influenza viruses from influenza-related hospital admissions in the St. Petersburg and Valencia sites of the Global Influenza Hospital Surveillance Network during the 2013/14 influenza season. AB - BACKGROUND: Continuous surveillance for genetic changes in circulating influenza viruses is needed to guide influenza prevention and control. OBJECTIVES: To compare intra-seasonal influenza genetic diversity of hemagglutinin in influenza A strains isolated from influenza hospital admissions collected at two distinct sites during the same season. STUDY DESIGN: Comparative phylogenetic analysis of full-length hemagglutinin genes from 77 isolated influenza A viruses from the St. Petersburg, Russian Federation and Valencia, Spain sites of the Global Influenza Hospital Surveillance Network (GIHSN) during the 2013/14 season. RESULTS: We found significant variability in A(H3N2) and A(H1N1)pdm09 viruses between the two sites, with nucleotide variation at antigenic positions much lower for A(H1N1)pdm09 than for A(H3N2) viruses. For A(H1N1)pdm09, antigenic sites differed by three to four amino acids from the vaccine strain, two of them common to all tested isolates. For A(H3N2) viruses, antigenic sites differed by six to nine amino acids from the vaccine strain, four of them common to all tested isolates. A fifth amino acid substitution in the antigenic sites of A(H3N2) defined a new clade, 3C.2. For both influenza A subtypes, pairwise amino acid distances between circulating viruses and vaccine strains were significantly higher at antigenic than at non-antigenic sites. Whereas A(H1N1)pdm09 viruses clustered with clade 6B and 94% of A(H3N2) with clade 3C.3, at both study sites A(H3N2) clade 3C.2 viruses emerged towards the end of the season, showing greater pairwise amino acid distances from the vaccine strain compared to the predominant clade 3C.3. CONCLUSIONS: Influenza A antigenic variants differed between St. Petersburg and Valencia, and A(H3N2) clade 3C.2 viruses were characterized by more amino acid differences from the vaccine strain, especially at the antigenic sites.

AB - With the advent of more precise technologies allowing manipulation of matter at nanoscopic scales and novel characterization techniques, a growing field of research is focused on magnetic materials of technical interest-such as Fe clusters-and their related physical-chemical processes. In this study, we present the results of the sequential oxidation process of the Fe13 cluster by considering the physical-chemistry properties of the ground state configurations of Fe13O n ([Formula: see text]) clusters. We develop an exhaustive ab initio study into the GGA approach and explore the effect of the chemisorption of oxygen on the structural properties, the chemical stability, the magnetization and the magnetic anisotropy energy (MAE) of the systems. Our results clearly indicate that: (i) one of the studied clusters, Fe13O17, presents the biggest electrophilicity index and the lowest chemical hardness, being the most reactive among the systems studied; (ii) the Fe13O10 exhibits a much more enhanced magnetization than other related clusters intended for health and technology applications (Sun et al 2007 J. Phys. Chem. C 111 4159-63), so that it might be a better candidate for those purposes; and (iii) the MAE presents a complex and intriguing landscape that encourages thinking about the plausible control of magnetic states focused on technical applications. PMID- 27690145 TI - Role of Surface Perfection in Chemical Force Microscopy. AB - In this paper we investigate the effect that the quality of the gold substrate has upon the distribution of adhesion force measurements in chemical force microscopy. Gold samples have been prepared by two protocols which give either predominantly single-crystal Au(111) or polycrystalline gold films on mica. Gold coated tips and surfaces were functionalized with self-assembled monolayers terminating in carboxylic groups, and more that 500 force-distance plots were taken. Analysis of these plots revealed a 50% narrower distribution of adhesion forces between monolayers prepared on single-crystal surfaces and monolayers prepared on polycrystalline gold, when measurements were repeated at a single point. However when measurements were taken over a 1-MUm2 area, the distribution of adhesion forces was similar for both samples. An explanation for this may lie in the size of the domains on the gold surface relative to the contact area of the tip.

AB - A series of lanthanide boroantimonates, namely, LnBSb2O8 (Ln = Sm 1, Eu 2, Gd 3, and Tb 4) have been successfully synthesized by high temperature solid-state reactions for the first time. They are isostructural and feature novel three dimensional (3D) frameworks composed of 2D [Sb3O12]9- layers interconnected by 1D [SbBO7]6- chains with remaining BO3 groups hanging on the walls of the 1D 6 membered-ring (MR) tunnels along the a-axis, and the lanthanide ions filled in the voids of the anionic structure. They exhibit high thermal stability (up to 900 degrees C). Luminescent studies suggest that compounds 1, 2, and 4 have potential application as orange, red, and green light luminescent materials, respectively. Magnetic measurements reveal ferromagnetic coupling interactions in compound 3 and antiferromagnetic coupling interactions between magnetic centers in compounds 1, 2, and 4.

AB - OBJECTIVE: To evaluate if selected phthalate exposure and flavonoid intake interact on breast cancer (BC) risk. MATERIAL AND METHODS: Interviews and urine samples were obtained from 233 women with histologically confirmed BC and 221 healthy controls matched by age and place of residence, from various states of northern Mexico. Urinary metabolites concentrations of diethyl phthalate (DEP), butyl benzyl phthalate (BBzP) and dioctyl phthalate (DOP) were determined by solid-phase extraction coupled with high-performance liquid chromatography/isotope dilution/tandem mass spectrometry. Using a semiquantitative food frequency questionnaire, consumption of five types of flavonoids (anthocyanidins, flavan-3-ols, flavanones, flavones and flavonols) was estimated according to three food groups: vegetables, fruits and legumes-oil seeds. RESULTS: A higher intake of anthocyanidins and flavan-3-ols (from vegetables), synergistically increased the negative association between BBzP and BC. No other significant flavonoid-phthalate multiplicative interactions on the risk for BC were found. CONCLUSION: The consumption of some flavonoids may interact with exposure to phthalates on the risk of BC. Epidemiological and underlying mechanisms information is still insufficient and requires further investigations.

AB - A second-generation approach to the synthesis of hydromorphone by oxidative dearomatization/Diels-Alder cycloaddition was investigated. Detailed analysis of the stereochemical outcome of the [4 + 2] cycloaddition was performed first on a truncated model system as well as on the material leading to ent-hydromorphone. The stereochemical assignments were made by NMR and X-ray methods. The second generation synthesis of hydromorphone was completed in both enantiomeric series. Improvements in the dearomatization conditions were attained using hypervalent iodine reagents instead of Pb(OAc)4. Electrochemical methods of oxidative dearomatization were also investigated. New conditions enabling the rearomatization of ring A from the methoxyketal were developed, and a formal synthesis of the natural enantiomer of hydromorphone was completed. Experimental and spectral data are provided for all new compounds. PMID- 27690148 TI - In search of the severity dimension of traffic events: Extended Delta-V as a traffic conflict indicator. AB - Most existing traffic conflict indicators do not sufficiently take into account the severity of the injuries resulting from a collision had it occurred. Thus far, most of the indicators that have been developed express the severity of a traffic encounter as their proximity to a collision in terms of time or space. This paper presents the theoretical framework and the first implementation of Extended Delta-V as a measure of traffic conflict severity in site-based observations. It is derived from the concept of Delta-V as it is applied in crash reconstructions, which refers to the change of velocity experienced by a road user during a crash. The concept of Delta-V is recognised as an important predictor of crash outcome severity. The paper explains how the measure is operationalised within the context of traffic conflict observations. The Extended Delta-V traffic conflict measure integrates the proximity to a crash as well as the outcome severity in the event a crash would have taken place, which are both important dimensions in defining the severity of a traffic event. The results from a case study are presented in which a number of traffic conflict indicators are calculated for interactions between left turning vehicles and vehicles driving straight through a signalised intersection. The results suggest that the Extended Delta-V indicator seems to perform well at selecting the most severe traffic events. The paper discusses how the indicator overcomes a number of limitations of traditional measures of conflict severity. While this is a promising first step towards operationalising an improved measure of traffic conflict severity, additional research is needed to further develop and validate the indicator.

AB - The aim of this study was to determine the molecular spectrum and frequency of deletional and nondeletional alpha-thalassemia (alpha-thal) mutations and the genotype-phenotype correlation in common mutations in the Azeri population of Northwestern Iran. A total of 1256 potential carriers with microcytic and hypochromic anemia and normal Hb A2 levels (<3.5%) and without iron deficiency anemia plus three fetuses were identified. Multiplex gap-polymerase chain reaction (gap-PCR) and sequencing for alpha-thal mutations were carried out. In 606 individuals, the alpha-globin gene was normal, but in 650 persons (51.6%) and three fetuses, 10 different mutations were detected. The most frequent deletional genotypes were as follows: alphaalpha/-alpha3.7 (61.7%), -alpha3.7/-alpha3.7 (11.9%), alphaalpha/-alpha4.2 (4.6%), alphaalpha/- -MED (4.3%) and alphaalpha/ (alpha)20.5 (3.8%). The most frequent nondeletional genotypes were alphaalpha/alphaIVS-I (-5 nt)alpha (HBA2: c.95+2_95+6delTGAGG) and alphaalpha/alphaPoly A2alpha [polyadenylation signal (polyA2) (AATAAA>AATGAA); HBA2: c.*96G>A] with frequencies of 1.08% and 0.92%, respectively. Meanwhile, 7.71% of individuals with a proven beta-thalassemia (beta-thal) mutation were found to also carry an alpha-thal mutation. Persons having two functional alpha globin genes showed lower mean corpuscular volume (MCV) and mean corpuscular hemoglobin (Hb) (MCH) values compared to those with one mutated alpha-globin gene, provided that they had normal beta-globin genes. Overall, the incidence of alpha-thal was 2.7% in the Azeri population in Northwestern Iran. Our results showed that the variability of alpha-thal mutations are high in the Azeri population and that alpha-thal mutations are highly heterogeneous in both deletional and nondeletional genotype aspects. PMID- 27690154 TI - Secretome derived from breast tumor cell lines alters the morphology of human umbilical vein endothelial cells. AB - Metastases, responsible for most of the solid tumor associated deaths, require angiogenesis and changes in endothelial cells. In this work, the effect of the secretomes of three breast tumor cell lines (MCF-7, MDA-MB-231 and ZR-75-30) on human umbilical vein endothelial cells (HUVEC) morphology was investigated. HUVEC treated with secretomes from breast cells were analyzed by confocal and time lapse microscopy. Secretomes from ZR-75-30 and MDA-MB-231 cells modify the morphology and adhesion of HUVEC. These changes may provoke the loss of endothelial monolayer integrity. In consequence, tumor cells could have an increased access to circulation, which would then enhance metastasis. PMID- 27690153 TI - Strategies for improving drug delivery: nanocarriers and microenvironmental priming. AB - INTRODUCTION: The ultimate goal in the field of drug delivery is to exclusively direct therapeutic agents to pathological tissues in order to increase therapeutic efficacy and eliminate side effects. This goal is challenging due to multiple transport obstacles in the body. Strategies that improve drug transport exploit differences in the characteristics of normal and pathological tissues. Within the field of oncology, these concepts have laid the groundwork for a new discipline termed transport oncophysics. Areas covered: Efforts to improve drug biodistribution have mainly focused on nanocarriers that enable preferential accumulation of drugs in diseased tissues. A less common approach to enhance drug transport involves priming strategies that modulate the biological environment in ways that favor localized drug delivery. This review discusses a variety of priming and nanoparticle design strategies that have been used for drug delivery. Expert opinion: Combinations of priming agents and nanocarriers are likely to yield optimal drug distribution profiles. Although priming strategies have yet to be widely implemented, they represent promising solutions for overcoming biological transport barriers. In fact, such strategies are not restricted to priming the tumor microenvironment but can also be directed toward healthy tissue in order to reduce nanoparticle uptake. PMID- 27690155 TI - Cyclosporin a induces renal episodic hypoxia. AB - AIM: Cyclosporin A (CsA) causes renal toxicity. The underlying mechanisms are incompletely understood, but may involve renal hypoxia and hypoxia-inducible factors (Hifs). We sought for hypoxia and Hif in mouse kidneys with CsA-induced toxicity, assessed their time course, Hif-mediated responses and the impact of interventional Hif upregulation. METHODS: Mice received CsA or its solvent cremophore for up to 6 weeks. Low salt diet (Na+ ?) was given in combination with CsA to enhance toxicity. We assessed fine morphology, renal function, blood oxygen level-dependent magnetic resonance imaging under room air and following changes in breathing gas composition which correlate with vascular reactivity, pimonidazole adducts (which indicate O2 tensions below 10 mmHg), Hif-alpha proteins, as well as expression of Hif target genes. Stable Hif upregulation was achieved by inducible, Pax8-rtTA-based knockout of von Hippel-Lindau protein (Vhl KO), which is crucial for Hif-alpha degradation. RESULTS: Cyclosporin A transiently increased renal deoxyhaemoglobin (R2*). Augmented vascular reactivity was observed at 2 h, but decreased at 24 h after CsA treatment. Na+ ?/CsA provoked chronic renal failure with tubular degeneration and interstitial fibrosis. Nephron segments at risk for injury accumulated pimonidazole adducts, as well as Hif-alpha proteins. Remarkably, Hif target gene expression remained unchanged, while factor-inhibiting Hif (Fih) was enhanced. Na+ ?/CsA/Vhl-KO aggravated morpho-functional outcome of chronic renal CsA toxicity. CONCLUSIONS: Cyclosporin A provokes episodic hypoxia in nephron segments most susceptible to chronic CsA toxicity. Fih is upregulated and likely blocks further Hif activity. Continuous tubular Hif upregulation via Vhl-KO worsens the outcome of chronic CsA induced renal toxicity.

AB - PURPOSE: The purpose of this work was to determine the predictive value of chemical exchange saturation transfer (CEST) metrics in brain metastases treated with stereotactic radiosurgery (SRS). METHODS: CEST spectra at a radiofrequency power of 0.52 uT were collected on a 3 Tesla (T) magnetic resonance imaging from 25 patients at three time points: pretreatment, 1 week, and 1 month post treatment. Amide proton transfer-weighted images and maps of the amplitude and width of Lorentzian-shaped CEST peaks and the relaxation-compensated AREX metric were constructed at the offset frequencies of amide, amine, and relayed nuclear Overhauser effect (NOE) from aliphatic groups as well as the broad magnetization transfer effect. Pretreatment CEST metrics, as well as CEST metric changes at 1 week post-treatment, were compared to changes in tumor volume at 1 month. RESULTS: Significant (P < 0.05) 1-week predictive metrics included NOE peak amplitude (R = 0.69) in normal-appearing white matter (NAWM) and width (R = 0.55) in tumor. Baseline NOE in contralateral NAWM was negatively correlated (R = -0.69) with volume changes at 1 month. Metrics-defined outside tumor margins had higher correlation with volume changes than tumor regions of interest. CONCLUSION: CEST metrics, in particular, the NOE peak amplitude, can predict volume changes 1 month post-SRS. Magn Reson Med 78:1110-1120, 2017.

AB - It is still an unresolved question how the visual system perceives surface lightness given the ambiguity of the sensory input signal. We studied lightness perception using two-dimensional images of variegated checkerboards shown as perspective projections of three-dimensional objects. We manipulated the contrast of a target check relative to its surround either by rendering the image under different viewing conditions or by introducing noncoincidental changes of the reflectance of the surfaces adjacent to the target. We examined the predictive power of the normalized contrast model (Zeiner & Maertens, 2014) for the different viewing conditions (plain view vs. dark and light transparency) as well as for the noncoincidental surround changes (only high or only low reflectances in the surround). The model accounted for lightness matches across different viewing conditions but not for the surround changes. The observed simultaneous contrast effects were smaller than what would be predicted by the model. We evaluated two model extensions that-both relying on contrast-predicted the observed data well. Both model extensions point to the importance of contrast statistics across space and/or time for the computation of lightness, but it awaits future testing to evaluate whether and how the visual system could represent such statistics. PMID- 27690158 TI - Clarifying signal detection theoretic interpretations of the Muller-Lyer and sound-induced flash illusions. AB - In a recent article, Witt, Taylor, Sugovic, and Wixted (2015) made several claims about the way the Muller-Lyer and sound-induced flash illusions should influence the signal detection theory criterion and sensitivity measures, c and d'. Here, we address some crucial conceptual inconsistencies in their simulation of the Muller-Lyer illusion and clarify a previous analysis of the sound-induced flash illusion from the literature that is misinterpreted in their discussion. Alternative signal detection theoretic interpretations of both illusions are offered. PMID- 27690159 TI - Further clarifying signal detection theoretic interpretations of the Muller-Lyer and sound-induced flash illusions. PMID- 27690160 TI - The perceived depth from disparity as function of luminance contrast. AB - Does human vision show the contrast invariance expected of an ideal stereoscopic system for computing depth from disparity? We used random-dot stereograms to investigate the luminance contrast effect on perceived depth from disparity. The perceived depth of disparity corrugations was measured by adjusting the length of a horizontal line to match the perceived depth of the corrugations at various luminance contrasts. At each contrast, the perceived depth increased with disparity up to a critical value, decreasing with further increases in disparity. Both the maximum perceived depth and the disparity modulation level where this maximum occurred changed as a sigmoid function of luminance contrast. These results show that perceived depth from disparity depends in a complex manner on the luminance contrast in the image, providing significant limitations on depth perception at low contrasts in a lawful manner but that are incompatible with existing models of cortical disparity processing.

PMID- 27690163 TI - Temporal synchrony is an effective cue for grouping and segmentation in the absence of form cues. AB - The synchronous change of a feature across multiple discrete elements, i.e., temporal synchrony, has been shown to be a powerful cue for grouping and segmentation. This has been demonstrated with both static and dynamic stimuli for a range of tasks. However, in addition to temporal synchrony, stimuli in previous research have included other cues which can also facilitate grouping and segmentation, such as good continuation and coherent spatial configuration. To evaluate the effectiveness of temporal synchrony for grouping and segmentation in isolation, here we measure signal detection thresholds using a global-Gabor stimulus in the presence/absence of a synchronous event. We also examine the impact of the spatial proximity of the to-be-grouped elements on the effectiveness of temporal synchrony, and the duration for which elements are bound together following a synchronous event in the absence of further segmentation cues. The results show that temporal synchrony (in isolation) is an effective cue for grouping local elements together to extract a global signal. Further, we find that the effectiveness of temporal synchrony as a cue for segmentation is modulated by the spatial proximity of signal elements. Finally, we demonstrate that following a synchronous event, elements are perceptually bound together for an average duration of 200 ms. PMID- 27690165 TI - What crowds in crowding? PMID- 27690166 TI - Visual input that matches the content of visual working memory requires less (not faster) evidence sampling to reach conscious access. AB - The content of visual working memory (VWM) affects the processing of concurrent visual input. Recently, it has been demonstrated that stimuli are released from interocular suppression faster when they match rather than mismatch a color that is memorized for subsequent recall. In order to investigate the nature of the interaction between visual representations elicited by VWM and visual representations elicited by retinal input, we modeled the perceptual processes leading up to this difference in suppression durations. We replicated the VWM modulation of suppression durations, and fitted sequential sampling models (linear ballistic accumulators) to the response time data. Model comparisons revealed that the data was best explained by a decrease in threshold for visual input that matches the content of VWM. Converging evidence was obtained by fitting similar sequential sampling models (shifted Wald model) to published datasets. Finally, to confirm that the previously observed threshold difference reflected processes occurring before rather than after the stimuli were released from suppression, we applied the same procedure to the data of an experiment in which stimuli were not interocularly suppressed. Here, we found no decrease in threshold for stimuli that match the content of VWM. We discuss our findings in light of a preactivation hypothesis, proposing that matching visual input taps into the same neural substrate that is already activated by a representation concurrently maintained in VWM, thereby reducing its threshold for reaching visual awareness. PMID- 27690167 TI - Age-dependent distractor suppression across the vision and motor domain. AB - The ability to inhibit distracting information-distractor suppression-is a fundamental process for the visual and motor systems. Whereas aging is typically linked to a general decline in cognitive processing, a specific impairment in distractor suppression is found during visual attention tasks. Despite this, the effect of aging on a human's capacity to inhibit distracting information during a motor task is currently unknown. Therefore, we tested the ability of young and older adults to inhibit distracting information during a visual attention (global local) and a motor (reaching) task. When faced with distractors, younger and older adults displayed significant behavioral impairments (accuracy and speed) across both tasks. However, these deficits were substantially enhanced in older adults. Intriguingly, the amount of distractor impairment observed within each participant was correlated across the visual and motor tasks, irrespective of age group. Thus, while all participants' ability to inhibit distractors was correlated across the visual and motor domain, older adults displayed a generalized distractor inhibition deficit. We propose that a shift from proactive to reactive control in older adults could explain such impairment. These results may have important implications regarding the ability of older adults to effectively deal with distractors during complex visuomotor tasks such as driving. PMID- 27690168 TI - Differential effects of visual uncertainty and contextual guidance on perceptual decisions: Evidence from eye and mouse tracking in visual search. AB - Visual search can be seen as a decision-making process that aims to assess whether a target is present or absent from a scene. In this perspective, eye movements collect evidence related to target detection and verification to guide the decision. We investigated whether, in real-world scenes, target detection and verification are differentially recruited in the decision-making process in the presence of prior information (expectations about target location) and perceptual uncertainty (noise). We used a mouse-tracking methodology with which mouse trajectories unveil components of decision-making and eye-tracking measures reflect target detection and verification. Indoor scenes were presented, including a target in usual or unusual locations or no target, and were degraded with additive noise (or no noise). Participants had to respond to the target's presence or absence. Degrading the scene delayed the decision due to increased verification times and reduced mouse velocity. Targets in unusual locations delayed the decision and deviated mouse trajectories toward the target-absent response. Detection times played a major role in these effects. Thus, target detection and verification processes influence decision-making by integrating the available sources of information differently and lead to an accumulation of evidence toward both the presence of a target and its absence. PMID- 27690169 TI - Luminance and chromatic signals interact differently with melanopsin activation to control the pupil light response. AB - Intrinsically photosensitive retinal ganglion cells (ipRGCs) express the photopigment melanopsin. These cells receive afferent inputs from rods and cones, which provide inputs to the postreceptoral visual pathways. It is unknown, however, how melanopsin activation is integrated with postreceptoral signals to control the pupillary light reflex. This study reports human flicker pupillary responses measured using stimuli generated with a five-primary photostimulator that selectively modulated melanopsin, rod, S-, M-, and L-cone excitations in isolation, or in combination to produce postreceptoral signals. We first analyzed the light adaptation behavior of melanopsin activation and rod and cones signals. Second, we determined how melanopsin is integrated with postreceptoral signals by testing with cone luminance, chromatic blue-yellow, and chromatic red-green stimuli that were processed by magnocellular (MC), koniocellular (KC), and parvocellular (PC) pathways, respectively. A combined rod and melanopsin response was also measured. The relative phase of the postreceptoral signals was varied with respect to the melanopsin phase. The results showed that light adaptation behavior for all conditions was weaker than typical Weber adaptation. Melanopsin activation combined linearly with luminance, S-cone, and rod inputs, suggesting the locus of integration with MC and KC signals was retinal. The melanopsin contribution to phasic pupil responses was lower than luminance contributions, but much higher than S-cone contributions. Chromatic red-green modulation interacted with melanopsin activation nonlinearly as described by a "winner-takes all" process, suggesting the integration with PC signals might be mediated by a postretinal site. PMID- 27690171 TI - The flash-lag effect and the flash-drag effect in the same display. AB - Visual motion distorts the perceived position of a stimulus. In the flash-drag effect (FDE), the perceived position of a flash appears to be shifted in the direction of nearby motion. In the flash-lag effect (FLE), a flash adjacent to a moving stimulus appears to lag behind. The FLE has been explained by several models, including the differential latency hypothesis, that a moving stimulus has a shorter processing latency than a flash does. The FDE even occurs when the flash is presented earlier than the moving stimulus, and it has been discussed whether this temporal property can be explained by the differential latency model. In the present study, we simultaneously quantified the FDE and FLE using the random jump technique (Murakami, 2001b) and compared their temporal properties. While the positional offset between a randomly jumping stimulus and a flashed stimulus determined the FLE, a drifting grating appeared next to the flash at various stimulus-onset asynchronies to induce the FDE. The grating presented up to 200 ms after the flash onset induced the FDE, whose temporal tuning was explained by a simple convolution model incorporating stochastic fluctuations of differential latency estimated from the FLE data and a transient sustained temporal profile of motion signals. Thus, a common temporal mechanism to compute the stimulus position in reference to surrounding stimuli governs both the FDE and the FLE. PMID- 27690170 TI - The crowding factor method applied to parafoveal vision. AB - Crowding increases with eccentricity and is most readily observed in the periphery. During natural, active vision, however, central vision plays an important role. Measures of critical distance to estimate crowding are difficult in central vision, as these distances are small. Any overlap of flankers with the target may create an overlay masking confound. The crowding factor method avoids this issue by simultaneously modulating target size and flanker distance and using a ratio to compare crowded to uncrowded conditions. This method was developed and applied in the periphery (Petrov & Meleshkevich, 2011b). In this work, we apply the method to characterize crowding in parafoveal vision (<3.5 visual degrees) with spatial uncertainty. We find that eccentricity and hemifield have less impact on crowding than in the periphery, yet radial/tangential asymmetries are clearly preserved. There are considerable idiosyncratic differences observed between participants. The crowding factor method provides a powerful tool for examining crowding in central and peripheral vision, which will be useful in future studies that seek to understand visual processing under natural, active viewing conditions.

AB - The reactivity of a representative set of 17 organozinc pivalates with 18 polyfunctional druglike electrophiles (informers) in Negishi cross-coupling reactions was evaluated by high-throughput experimentation protocols. The high fidelity scaleup of successful reactions in parallel enabled the isolation of sufficient material for biological testing, thus demonstrating the high value of these new solid zinc reagents in a drug-discovery setting and potentially for many other applications in chemistry. Principal component analysis (PCA) clearly defined the independent roles of the zincates and the informers toward druggable space coverage. PMID- 27690174 TI - Sensitive Detection of Radiation-Induced Medulloblastomas after Acute or Protracted Gamma-Ray Exposures in Ptch1 Heterozygous Mice Using a Radiation Specific Molecular Signature. AB - Recently reported studies have led to a heightened awareness of the risks of cancer induced by diagnostic radiological imaging, and in particular, the risk of brain cancer after childhood CT scans. One feature of Ptch1+/- mice is their sensitivity to radiation-induced medulloblastomas (an embryonic cerebellar tumor) during a narrow window of time centered on the days around birth. Little is known about the dynamics of how dose protraction interacts with such narrow windows of sensitivity in individual tissues. Using medulloblastomas from irradiated Ptch1+/ mice with a hybrid C3H * C57BL/6 F1 genetic background, we previously showed that the alleles retained on chromosome 13 (which harbors the Ptch1 gene) reveal two major mechanisms of loss of the wild-type allele. The loss of parental alleles from the telomere extending up to or past the Ptch1 locus by recombination (spontaneous type) accounts for almost all medulloblastomas in nonirradiated mice, while tumors in irradiated mice often exhibited interstitial deletions, which start downstream of the wild-type Ptch1 and extend up varying lengths towards the centromere (radiation type). In this study, Ptch1+/- mice were exposed to an acute dose of either 100 or 500 mGy gamma rays in utero or postnatally, or the same radiation doses protracted over a four-day period, and were monitored for medulloblastoma development. The results showed dose- and age dependent radiation-induced type tumors. Furthermore, the size of the radiation induced deletion differed with the dose rate. The results of this work suggest that tumor latency may be related to the size of the deletion. In this study, 500 mGy exposure produced radiation-induced type tumors at all ages and dose rates, while 100 mGy exposure did not significantly produce radiation-induced type tumors. The radiation signature allows for unique mechanistic insight into the action of radiation to induce DNA lesions with known causal relationship to a specific tumor type, particularly for doses and dose rates that are relevant to both diagnostic and accidental radiological exposures.

AB - Long-term effects of in utero exposure to ionizing radiation remain poorly quantified in humans. In this study, the risk of hematologic malignancies was investigated in offspring of female workers of the Mayak Production Association, a large Russian nuclear facility. Excess relative risks (ERR) for exposure to gamma radiation and plutonium were estimated in a cohort of 8,466 offspring who were born between January 1, 1948 and December 31, 1988 and followed until 2009. An unstable linear ERR of 1.12 (95% CI 0.11-3.44) per 100 mGy gamma exposure in utero was estimated based on 32 incident hematologic malignancies in 277,002 person-years under risk. The ERR was increased in the dose category 20-79 mGy gamma exposure in utero (1.75, 95% CI 0.04; 5.63), while the other dose categories showed decreased or unstable estimates. Leukemia showed an ERR of 1.76 (95% CI 0.01-8.33) per 100 mGy based on 13 cases. There was no consistent association with plutonium exposure. While an increased risk of hematologic malignancies after gamma exposure in utero was suggested, the small numbers prevented more definitive conclusions. PMID- 27690176 TI - The role of cognitive control mechanisms in selective attention towards emotional stimuli. AB - The role of cognitive control mechanisms in reducing interference from emotionally salient distractors was investigated. In two experiments, participants performed a flanker task in which target-distractor affective compatibility and cognitive load were manipulated. Differently from past studies, targets and distractors were presented at separate spatial locations and cognitive load was not domain-specific. In Experiment 1, words (positive vs. negative) and faces (angry, happy or neutral faces), were used respectively as targets and distractors, whereas in Experiment 2, both targets (happy vs. angry) and distractors were faces. Findings showed interference from distractor processing only when cognitive load was high. The present findings indicate that, when targets and distractors are presented at different spatial locations, cognitive control mechanisms are involved in preventing interference from positive (Exp. 1) or negative distractors (Exp. 2). The role of stimulus valence and type is also discussed with regard to different patterns of interference observed. PMID- 27690173 TI - Diffusion-weighted breast MRI: Clinical applications and emerging techniques. AB - : Diffusion-weighted MRI (DWI) holds potential to improve the detection and biological characterization of breast cancer. DWI is increasingly being incorporated into breast MRI protocols to address some of the shortcomings of routine clinical breast MRI. Potential benefits include improved differentiation of benign and malignant breast lesions, assessment and prediction of therapeutic efficacy, and noncontrast detection of breast cancer. The breast presents a unique imaging environment with significant physiologic and inter-subject variations, as well as specific challenges to achieving reliable high quality diffusion-weighted MR images. Technical innovations are helping to overcome many of the image quality issues that have limited widespread use of DWI for breast imaging. Advanced modeling approaches to further characterize tissue perfusion, complexity, and glandular organization may expand knowledge and yield improved diagnostic tools. LEVEL OF EVIDENCE: 5 J. Magn.

AB - This study evaluated antibiotic resistance and the related genes in total 47 Aeromonas veronii isolates from pet fish, eel (Anguilla japonica) and koi (Cyprinus carpio) in Korea. In comparison with the antibiotic susceptibilities of isolates from eel and koi, those of pet fish were more resistant to ceftiofur, aminoglycosides, tetracycline and nitrofurantoin. And isolates from pet fish showed high prevalences of class 1 integron, quinolones and tetracycline resistance determinants than those from eel and koi. Repetitive-element palindromic PCR (rep-PCR) showed larger diversities among A. veronii isolates. Collectively, pet fish may be a reservoir for multiple clones of A. veronii involved in antibiotic resistance. In this aspect, imported fish in the aquaculture trade should be steadily and continually screened for bacterial antibiotic resistance and related genes. PMID- 27690180 TI - Exopolymer production as a function of cell permeability and death in a diatom (Thalassiosira weissflogii) and a cyanobacterium (Synechococcus elongatus). AB - Exopolymer particles are found throughout the ocean and play a significant biogeochemical role in carbon cycling. Transparent exopolymer particles (TEP) are composed of acid polysaccharides, and Coomassie staining particles (CSP) are proteins. TEPs have been extensively studied in the ocean, while CSP have been largely overlooked. The objective of this research was to determine the role of stress and cell permeability in the formation of TEP and CSP. The diatom Thalassiosira weissflogii and cyanobacterium Synechococcus elongatus were grown in batch cultures and exposed to hydrogen peroxide (0, 10, and 100 MUM) as an environmental stressor. There was no correlation between TEP and CSP concentrations, indicating that they are different populations of particles rather than different chemical components of the same particles. CSP concentrations were not affected by hydrogen peroxide concentration and did not correlate with indicators of stress and cell death. In contrast, TEP concentrations in both taxa were correlated with a decrease in the effective quantum yield of photosystem II, increased activity of caspase-like enzymes, and an increase in the proportion of the population with permeable cell membranes, indicating that TEP production was associated with the process of cell death. These data show that different environmental factors and physiological processes affected the production of TEP and CSP by phytoplankton. TEP and CSP are separate populations of exopolymer particles with potentially different biogeochemical roles in the ocean.

AB - A method to extend the scope of the aza-Piancatelli reaction between 2 furylcarbinols and anilines is depicted. We found that 1,1,1,3,3,3-hexafluoro-2 propanol (HFIP) is the solvent of choice for this transformation, as it outcompetes the usual solvents in terms of rate and yield. Side reactions and other issues raised by the title reaction are prevented, thereby providing an avenue to complex molecules that were previously inaccessible. Lewis acidity studies and computations were carried out to unveil the role of HFIP. Based on these results, we propose that HFIP is, in fact, acting as a Lewis acid and that its acidity can be enhanced when combined with a calcium(II) salt. PMID- 27690182 TI - Differences in treatment goals and perception of symptom burden between patients with myeloproliferative neoplasms (MPNs) and hematologists/oncologists in the United States: Findings from the MPN Landmark survey. AB - BACKGROUND: This analysis of the myeloproliferative neoplasm (MPN) Landmark survey evaluated gaps between patient perceptions of their disease management and physician self-reported practices. METHODS: The survey included 813 patient respondents who had MPNs (myelofibrosis [MF], polycythemia vera [PV], or essential thrombocythemia [ET]) and 457 hematologist/oncologist respondents who treated patients with these conditions. RESULTS: Greater proportions of physician respondents reported using prognostic risk classifications (MF, 83%; PV, 59%; ET, 77%) compared with patient recollections (MF, 54%; PV, 17%; ET, 31%). Most physician respondents reported that their typical symptom assessments included asking patients about the most important symptoms or a full list of symptoms, whereas many patient respondents reported less specific assessments (eg, they were asked how they were feeling). Many patient respondents did not recognize common symptoms as MPN-related. For example, approximately one-half or more did not believe difficulty sleeping resulted from their MPN (MF, 49%; PV, 64%; ET, 76%). Physician respondents underestimated the proportion of patients who had symptomatic PV or ET at diagnosis compared with patient respondents. There was discordance regarding treatment goals: among patient respondents with MF or PV, "slow/delay progression of condition" was the most important treatment goal, whereas physician respondents reported "symptom improvement" and "prevention of vascular/thrombotic events," respectively. Finally, more than one-third of patient respondents were not "very satisfied" with their physician's overall management/communication. CONCLUSIONS: The care and satisfaction of patients with MPN may be improved with increased patient education and improved patient physician communication. Cancer 2017;123:449-458.

AB - Corals are known to contain a diverse microbiota that plays a paramount role in the physiology and health of holobiont. However, few studies have addressed the variability of bacterial communities within the coral host. In this study, bacterial community composition from the mucus, tissue and skeleton of the scleractinian coral Oculina patagonica were investigated seasonally at two locations in the Western Mediterranean Sea, to further understand how environmental conditions and the coral microbiome structure are related. We used denaturing gradient gel electrophoresis in combination with next-generation sequencing and electron microscopy to characterize the bacterial community. The bacterial communities were significantly different among coral compartments, and coral tissue displayed the greatest changes related to environmental conditions and coral health status. Species belonging to the Rhodobacteraceae and Vibrionaceae families form part of O. patagonica tissues core microbiome and may play significant roles in the nitrogen cycle. Furthermore, sequences related to the coral pathogens, Vibrio mediterranei and Vibrio coralliilyticus, were detected not only in bleached corals but also in healthy ones, even during cold months. This fact opens a new view onto unveiling the role of pathogens in the development of coral diseases in the future.

AB - To compensate the limitations of bone tissue magnetic resonance imaging (MRI), a series of gadolinium (Gd3+ ) substituted beta-Tricalcium phosphate [beta-TCP, beta-Ca3 (PO4 )2 ] were developed. All the powders were characterized using XRD, Raman spectroscopy, Rietveld refinement of the XRD data and the studies confirmed the Gd3+ occupancy at Ca2+ (1), Ca2+ (2) and Ca2+ (3) lattice sites of beta-Ca3 (PO4 )2. HR-TEM analysis revealed the spherical nature of particles with diameter about 100 nm. The Gd3+ doped beta-Ca3 (PO4 )2 exhibited non-toxic behaviour to MG 63 cells in vitro and the room temperature magnetic field versus magnetization measurements confirmed its paramagnetic behaviour. MRI analysis revelas that it shorten both T1 and T2 proton relaxation times, thus influencing both r1 and r2 relaxivity values that reach 61.97 mM-1 s-1 and 73.35 mM-1 s-1 .

PMID- 27690184 TI - Are reprogrammed cells a useful tool for studying dopamine dysfunction in psychotic disorders? A review of the current evidence. AB - Since 2006, reprogrammed cells have increasingly been used as a biomedical research technique in addition to neuro-psychiatric methods. These rapidly evolving techniques allow for the generation of neuronal sub-populations, and have sparked interest not only in monogenetic neuro-psychiatric diseases, but also in poly-genetic and poly-aetiological disorders such as schizophrenia (SCZ) and bipolar disorder (BPD). This review provides a summary of 19 publications on reprogrammed adult somatic cells derived from patients with SCZ, and five publications using this technique in patients with BPD. As both disorders are complex and heterogeneous, there is a plurality of hypotheses to be tested in vitro. In SCZ, data on alterations of dopaminergic transmission in vitro are sparse, despite the great explanatory power of the so-called DA hypothesis of SCZ. Some findings correspond to perturbations of cell energy metabolism, and observations in reprogrammed cells suggest neuro-developmental alterations. Some studies also report on the efficacy of medicinal compounds to revert alterations observed in cellular models. However, due to the paucity of replication studies, no comprehensive conclusions can be drawn from studies using reprogrammed cells at the present time. In the future, findings from cell culture methods need to be integrated with clinical, epidemiological, pharmacological and imaging data in order to generate a more comprehensive picture of SCZ and BPD. PMID- 27690187 TI - Polymer-Lipid Nanoparticles for Systemic Delivery of mRNA to the Lungs. AB - Therapeutic nucleic acids hold great promise for the treatment of disease but require vectors for safe and effective delivery. Synthetic nanoparticle vectors composed of poly(beta-amino esters) (PBAEs) and nucleic acids have previously demonstrated potential utility for local delivery applications. To expand this potential utility to include systemic delivery of mRNA, hybrid polymer-lipid nanoformulations for systemic delivery to the lungs were developed. Through coformulation of PBAEs with lipid-polyethylene glycol (PEG), mRNA formulations were developed with increased serum stability and increased in vitro potency. The formulations were capable of functional delivery of mRNA to the lungs after intravenous administration in mice. To our knowledge, this is the first report of the systemic administration of mRNA for delivery to the lungs using degradable polymer-lipid nanoparticles.

PMID- 27690189 TI - Synthesis and characterization of divinyl-fumarate poly-epsilon-caprolactone for scaffolds with controlled architectures. AB - A vinyl-terminated polycaprolactone has been developed for tissue engineering applications using a one-step synthesis and functionalization method based on ring opening polymerization (ROP) of epsilon-Caprolactone, with hydroxyl ethyl vinyl ether (HEVE) acting both as the initiator of ROP and as photo-curable functional group. The proposed method employs a catalyst based on aluminium, instead of the most popular Tin(II) 2-ethylhexanoate, to reduce the cytotoxicity. Following the synthesis of the vinyl-terminated polycaprolactone, its reaction with fumaryl chloride (FuCl) results in a divinyl-fumarate polycaprolactone (VPCLF). The polymers obtained were thoroughly characterized using Fourier transform infrared spectroscopy (FTIR) and gel permeation chromatography (GPC) techniques. The polymer has been successfully employed, in combination with N vinyl pyrrolidone (NVP), to fabricate films and computer-designed porous scaffolds by micro-stereolithography (MU-SL) with gyroid and diamond architectures. Characterization of the networks indicated the influence of NVP content on the network properties. Human mesenchymal stem cells adhered and spread onto VPCLF/NVP networks showing good biological properties and no cytotoxic effect. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - A vertical graphene heterostructure field-effect transistor (VGHFET) using an ultrathin ferroelectric film as a tunnel barrier is developed. The heterostructure is capable of providing new degrees of tunability and functionality via coupling between the ferroelectricity and the tunnel current of the VGHFET, which results in a high-performance device. The results pave the way for developing novel atomic-scale 2D heterostructures and devices.

AB - OBJECTIVE: Drivers' behaviors such as violations and errors have been demonstrated to predict crash involvement among young Omani drivers. However, there is a dearth of studies linking risky driving behaviors to the personality of young drivers. The aim of the present study was to assess such traits within a sample of young Omani drivers (as measured through the behavioral inhibition system [BIS] and the behavioral activation system [BAS]) and determine links with aberrant driving behaviors and self-reported crash involvement. METHODS: A cross sectional study was conducted at the Sultan Qaboos University that targeted all licensed Omani's undergraduate students. A total of 529 randomly selected students completed the self-reported questionnaire that included an assessment of driving behaviors (e.g., Driver Behaviour Questionnaire, DBQ) as well as the BIS/BAS measures. RESULTS: A total of 237 participants (44.8%) reported involvement in at least one crash since being licensed. Young drivers with lower BIS-Anxiety scores and higher BAS-Fun Seeking tendencies as well as male drivers were more likely to report driving violations. Statistically significant gender differences were observed on all BIS and BAS subscales (except for BAS-Fun) and the DBQ subscales, because males reported higher trait scores. Though personality traits were related to aberrant driving behaviors at the bivariate level, the constructs were not predictive of engaging in violations or errors. Furthermore, consistent with previous research, a supplementary multivariate logistic regression analysis revealed that only driving experience was predictive of crash involvement. CONCLUSIONS: The findings highlight that though personality traits influence self-reported driving styles (and differ between the genders), the relationship with crash involvement is not as clear. This article further outlines the key findings of the study in regards to understanding core psychological constructs that increase crash risk.

PMID- 27690193 TI - How Respiratory Pathogens Contribute to Lamb Mortality in a Poorly Performing Bighorn Sheep ( Ovis canadensis ) Herd. AB - We evaluated bighorn sheep ( Ovis canadensis ) ewes and their lambs in captivity to examine the sources and roles of respiratory pathogens causing lamb mortality in a poorly performing herd. After seven consecutive years of observed December recruitments of <10%, 13 adult female bighorn sheep from the remnant Gribbles Park herd in Colorado, US were captured and transported to the Thorne-Williams Wildlife Research Center in Wyoming in March 2013. Ewes were sampled repeatedly over 16 mo. In April 2014, ewes were separated into individual pens prior to lambing. Upon death, lambs were necropsied and tested for respiratory pathogens. Six lambs developed clinical respiratory disease and one lamb was abandoned. Pathology from an additional six lambs born in 2013 was also evaluated. Mycoplasma ovipneumoniae , leukotoxigenic Mannheimia spp., leukotoxigenic Bibersteinia trehalosi , and Pasteurella multocida all contributed to lamb pneumonia. Histopathology suggested a continuum of disease, with lesions typical of pasteurellosis predominating in younger lambs and lesions typical of mycoplasmosis predominating in older lambs. Mixed pathology was observed in lambs dying between these timeframes. We suspected that all the ewes in our study were persistently infected and chronically shedding the bacteria that contributed to summer lamb mortality. PMID- 27690194 TI - PREVALENCE AND POTENTIAL IMPACT OF TOXOPLASMA GONDII ON THE ENDANGERED AMARGOSA VOLE (MICROTUS CALIFORNICUS SCIRPENSIS), CALIFORNIA, USA. AB - We investigated the prevalence of Toxoplasma gondii in 2011-15 to assess its potential threat on the endangered Amargosa vole ( Microtus californicus scirpensis) in California, US. Surveillance was simultaneously performed on populations of syntopic rodent species. We detected antibodies to T. gondii in sera from 10.5% of 135 wild-caught Amargosa voles; 8% of 95 blood samples were PCR-positive for the T. gondii B1 gene, and 5.0% of 140 sympatric rodent brain samples were PCR-positive. Exposure to T. gondii did not change the probability that an animal would be recaptured in the field study. Behavioral response to domestic cat ( Felis catus ) and bobcat ( Lynx rufus ) urine was evaluated in five nonendangered Owens Valley voles ( Microtus californicus vallicola) as surrogates for Amargosa voles and seven uninfected controls. Voles showed mild attraction to mouse urine and had neutral reactions to domestic cat urine whether or not infected. Time spent near bobcat urine was approximately twice as high in infected than in uninfected voles (although not statistically significant). The presence of T. gondii in wild Amargosa vole and sympatric rodent populations may hinder the endangered Amargosa vole population's ability to recover in the wild. PMID- 27690195 TI - Associations among Habitat Characteristics and Meningeal Worm Prevalence in Eastern South Dakota, USA. AB - Few studies have evaluated how wetland and forest characteristics influence the prevalence of meningeal worm ( Parelaphostrongylus tenuis ) infection of deer throughout the grassland biome of central North America. We used previously collected, county-level prevalence data to evaluate associations between habitat characteristics and probability of meningeal worm infection in white-tailed deer ( Odocoileus virginianus ) across eastern South Dakota, US. The highest-ranked binomial regression model for detecting probability of meningeal worm infection was spring temperature + summer precipitation + percent wetland; weight of evidence (wi=0.71) favored this model over alternative models, though predictive capability was low (Receiver operating characteristic=0.62). Probability of meningeal worm infection increased by 1.3- and 1.6-fold for each 1-cm and 1-C increase in summer precipitation and spring temperature, respectively. Similarly, probability of infection increased 1.2-fold for each 1% increase in wetland habitat. Our findings highlight the importance of wetland habitat in predicting meningeal worm infection across eastern South Dakota. Future research is warranted to evaluate the relationships between climatic conditions (e.g., drought, wet cycles) and deer habitat selection in maintaining P. tenuis along the western boundary of the parasite. PMID- 27690196 TI - Studies on fluid dynamics of the flow field and gas transfer in orbitally shaken tubes. AB - Orbitally shaken cylindrical bioreactors [OrbShake bioreactors (OSRs)] without an impeller or sparger are increasingly being used for the suspension cultivation of mammalian cells. Among small volume OSRs, 50-mL tubes with a ventilated cap (OSR50), originally derived from standard laboratory centrifuge tubes with a conical bottom, have found many applications including high-throughput screening for the optimization of cell cultivation conditions. To better understand the fluid dynamics and gas transfer rates at the liquid surface in OSR50, we established a three-dimensional simulation model of the unsteady liquid forms (waves) in this vessel. The studies verified that the operating conditions have a large effect on the interfacial surface. The volumetric mass transfer coefficient (kL a) was determined experimentally and from simulations under various working conditions. We also determined the liquid-phase mass transfer coefficient (kL ) and the specific interfacial area (a) under different conditions to demonstrate that the value of a affected the gas transfer rate more than did the value of kL . High oxygen transfer rates, sufficient for supporting the high-density culture of mammalian cells, were found. Finally, the average axial velocity of the liquid was identified to be an important parameter for maintaining cells in suspension. Overall these studies provide valuable insights into the preferable operating conditions for the OSR50, such as those needed for cell cultures requiring high oxygen levels.

PMID- 27690198 TI - E-cigarette aerosols induce lower oxidative stress in vitro when compared to tobacco smoke. AB - Tobacco smoking is a risk factor for various diseases. The underlying cellular mechanisms are not fully characterized, but include oxidative stress, apoptosis, and necrosis. Electronic-cigarettes (e-cigarettes) have emerged as an alternative to and a possible means to reduce harm from tobacco smoking. E-cigarette vapor contains significantly lower levels of toxicants than cigarette smoke, but standardized methods to assess cellular responses to exposure are not well established. We investigated whether an in vitro model of the airway epithelium (human bronchial epithelial cells) and commercially available assays could differentiate cellular stress responses to aqueous aerosol extracts (AqE) generated from cigarette smoke and e-cigarette aerosols. After exposure to AqE concentrations of 0.063-0.500 puffs/mL, we measured the intracellular glutathione ratio (GSH:GSSG), intracellular generation of oxidant species, and activation of the nuclear factor erythroid-related factor 2 (Nrf2)-controlled antioxidant response elements (ARE) to characterize oxidative stress. Apoptotic and necrotic responses were characterized by increases in caspase 3/7 activity and reductions in viable cell protease activities. Concentration-dependent responses indicative of oxidative stress were obtained for all endpoints following exposure to cigarette smoke AqE: intracellular generation of oxidant species increased by up to 83%, GSH:GSSG reduced by 98.6% and transcriptional activation of ARE increased by up to 335%. Caspase 3/7 activity was increased by up to 37% and the viable cell population declined by up to 76%. No cellular stress responses were detected following exposure to e-cigarette AqE. The methods used were suitably sensitive to be employed for comparative studies of tobacco and nicotine products. PMID- 27690199 TI - Electronic cigarette aerosol induces significantly less cytotoxicity than tobacco smoke. AB - Electronic cigarettes (E-cigarettes) are a potential means of addressing the harm to public health caused by tobacco smoking by offering smokers a less harmful means of receiving nicotine. As e-cigarettes are a relatively new phenomenon, there are limited scientific data on the longer-term health effects of their use. This study describes a robust in vitro method for assessing the cytotoxic response of e-cigarette aerosols that can be effectively compared with conventional cigarette smoke. This was measured using the regulatory accepted Neutral Red Uptake assay modified for air-liquid interface (ALI) exposures. An exposure system, comprising a smoking machine, traditionally used for in vitro tobacco smoke exposure assessments, was adapted for use with e-cigarettes to expose human lung epithelial cells at the ALI. Dosimetric analysis methods using real-time quartz crystal microbalances for mass, and post-exposure chemical analysis for nicotine, were employed to detect/distinguish aerosol dilutions from a reference Kentucky 3R4F cigarette and two commercially available e-cigarettes (Vype eStick and ePen). ePen aerosol induced 97%, 94% and 70% less cytotoxicity than 3R4F cigarette smoke based on matched EC50 values at different dilutions (1:5 vs. 1:153 vol:vol), mass (52.1 vs. 3.1 MUg/cm2) and nicotine (0.89 vs. 0.27 MUg/cm2), respectively. Test doses where cigarette smoke and e-cigarette aerosol cytotoxicity were observed are comparable with calculated daily doses in consumers. Such experiments could form the basis of a larger package of work including chemical analyses, in vitro toxicology tests and clinical studies, to help assess the safety of current and next generation nicotine and tobacco products.

AB - Recent data strongly suggest an association between the current outbreak of ZIKA virus (ZIKV) in many countries of Central and South America and a sharp increase in the detection of microcephaly and fetal malformations. The link with brain defect, which has been detected mainly in some areas of Brazil, is supported by the following evidence: (1) ZIKV transmission from infected pregnant women to their fetuses; (2) the potential of ZIKV to determine a specific congenital fetal syndrome characterized by abnormalities involving primarily the developing brain and eye. In particular, the risk of transmission and congenital disease appears to be restricted to mother's infection during the first trimester of pregnancy. Among brain defects, microcephaly, brain calcifications, and ventriculomegaly are the most frequent abnormalities of the central nervous system detected so far. However, relevant information on effect of maternal infection with ZIKV on the fetus is still limited. In this review, we focus our attention on current knowledge about ZIKV infection in pregnancy, discussing relevant issues and open problems which merit further investigation.

PMID- 27690205 TI - Baseline adiponectin and leptin levels in predicting an increased risk of disease activity in rheumatoid arthritis: A meta-analysis and systematic review. AB - To determine the pathogenic role of adipokines, such as adiponectin and leptin, in rheumatoid arthritis (RA) by investigating whether serum levels of these adipokines correlated with disease activity in RA patients. Medline, Cochrane, EMBASE and Google Scholar were searched for studies published until 5 November 2015 reporting serum levels of leptin and adiponectin and measures of disease activity including DAS scores and radiographic progression scores (such as total change in SHS scores and number of erosions). Secondary outcomes included pain scores, functional status and health questionnaires. Only randomized controlled trials, cohort studies, or two-armed prospective or retrospective studies were included. A chi2-based test of homogeneity was performed using Cochran's Q statistic and I2. A total of 917 predominantly female participants (average age range, 39-56 years) from six prospective cohort studies were included for assessment. A fixed-effects analysis was applied for leptin levels due to lack of heterogeneity among the studies (Q = 4.4364; I2 = 32.38). A random-effects analysis was applied to serum levels of adiponectin because of significant heterogeneity between studies (Q = 4.444, I2 = 77.50%). Serum leptin levels were higher in RA patients with high disease activity (pooled SMD: 0.53, 95% CI: 0.24 0.82); however, serum adiponectin levels did not correlate with RA disease activity (pooled OR: 1.38, 95% CI: 0.77-2.47). The meta-analysis provides an additional factor to determine high disease activity index in RA, that is, serum leptin levels, which can be of benefit when choosing treatment strategies. PMID- 27690206 TI - The Interaction of Obesity and Nocturnal Hypoxemia on Cardiovascular Consequences in Adults with Suspected Obstructive Sleep Apnea. A Historical Observational Study. AB - RATIONALE: The interrelationships between obstructive sleep apnea (OSA) and obesity are complex and bidirectional; however, current evidence regarding their combined effect on cardiovascular risk is limited and conflicting. Animal studies suggest that obesity may exacerbate the cardiovascular consequences of intermittent hypoxemia. OBJECTIVES: In this historical observational study, we investigated whether obesity increases the effect of nocturnal hypoxemia on the incidence of cardiovascular events in adults with suspected OSA. METHODS: All adults with suspected OSA who underwent diagnostic polysomnography at a large academic hospital between 1994 and 2010 were linked to provincial health administrative data to determine a composite cardiovascular outcome (hospitalization due to heart failure, myocardial infarction, stroke, or revascularization procedures). Using a competing-risk model and controlling for confounders, hazards were compared between four groups: group 1 comprised obese patients (body mass index >30 kg/m2) with oxygen desaturation (>9 min of sleep spent with SaO2 <90%); group 2 comprised obese patients without desaturation; group 3 comprised nonobese patients with desaturation; and group 4 comprised nonobese patients without desaturation. Interaction was measured using the relative excess risk due to interaction. MEASUREMENTS AND MAIN RESULTS: A total of 10,149 participants were followed, with 17%, 25%, 8%, and 50% in groups 1-4, respectively. Over a median of 7.8 years, 896 (8.8%) first cardiovascular events occurred. Group 1 was associated with the highest hazard compared with the other groups, using group 4 as a reference (hazard ratio [HR] for group 1, 1.84; 95% confidence interval [CI], 1.46-2.32; HR for group 2, 1.59, 95% CI, 1.29-1.95; HR for group 3, 1.51; 95% CI, 1.15-1.98). The relative excess risk due to interaction was -0.25 (95% CI, -0.78 to 0.27), indicating no interaction. CONCLUSIONS: In adults with suspected OSA, the highest cardiovascular risk was found in obese patients with nocturnal oxygen desaturation; however, the effect of these two factors together does not exceed the effect of each factor considered individually. PMID- 27690207 TI - Prehospital Nitroglycerin in Tachycardic Chest Pain Patients: A Risk for Hypotension or Not? AB - BACKGROUND: The American Heart Association guidelines (AHA) guidelines list tachycardia as a contraindication for the administration of nitroglycerin (NTG), despite limited evidence of adverse events. We sought to determine whether NTG administered for chest pain was a predictor of hypotension (systolic blood pressure <90 mmHg) in patients with tachycardia, compared to patients without tachycardia (50>= heart rate <=100). METHODS: We performed a retrospective cohort study using patient care reports completed by basic life support (BLS) providers in a large urban Canadian EMS system for the period 2010-2012. We used logistic regression to test the association between post-NTG hypotension and tachycardia, independent of pre-NTG blood pressure, age, sex, and comorbidities. Using identical models, we tested four secondary outcomes (drop in blood pressure, reduced consciousness, bradycardia, and cardiac arrest). RESULTS: The cohort included 10,308 patients who were administered NTG by BLS in the prehospital setting; 2,057 (20%) of patients were tachycardic before NTG administration. Hypotension occurred in 320 of all patients (3.1%): 239 without tachycardia (2.9%) and 81 with tachycardia (3.9%). Compared to non-tachycardic patients, tachycardic patients showed increased adjusted odds of hypotension (AOR: 1.60; 95% CI: 1.23-2.08) or of a drop in blood pressure of 30mm Hg or greater (AOR: 1.11; CI: 1.00-1.24). Tachycardia was associated with decreased odds of bradycardia (OR: 0.33; CI: 0.17-0.64). We did not find a significant association between tachycardia and either post-NTG reduced level of consciousness or cardiac arrest. We did find a strong, significant association between pre-NTG blood pressure and post-NTG hypotension (AOR for units of 10mmHg: 0.64; CI: 0.61-0.69). CONCLUSION: Hypotension following prehospital administration of NTG was infrequent in patients with chest pain. However, while the absolute risk of NTG induced hypotension was low, patients with pre-NTG tachycardia had a significant increase in the relative risk of hypotension. In addition, hypotension occurred most frequently in patients presenting with a lower pre-NTG blood pressure, which may prove to be a more discriminating basis for future guidelines. EMS medical directors should review BLS chest pain protocols to weigh the benefits of NTG administration against its risks. PMID- 27690208 TI - Genomic feature extraction and comparison based on global alignment of ChIP sequencing data. AB - Enhanced accuracy and high-throughput capability in capturing genetic activities lead ChIP-sequencing technology to be applied prevalently in diverse study for tackling DNA-protein interaction problems. Till now, such questions as deciding suitable ChIP-seq arguments and comparing sample quality still haunt biologists. We propose the methods for answering such questions as deciding optimal argument pairs in global alignment of ChIP sequencing data; then we employ a modern signal processing approach to extract inherent genomic features from the global alignments of transcriptional binding activities; together with pairwise comparison from intra- and inter-sample perspectives; thus we can further determine alignment quality and decide the optimal candidate for multi-source heterogeneous high-throughput sequences. The work provides a practical approach to quantitatively compare the alignment quality for heterogeneous sequencing data, especially in determining the efficiency of transcriptional binding from replicate samples, thus it helps to exploit the potentiality of ChIP-seq for deep comprehension of inherent biological meanings from the high-throughput genomic sequences. PMID- 27690209 TI - Characterization of the transcriptomes and cuticular protein gene expression of alate adult, brachypterous neotenic and adultoid reproductives of Reticulitermes labralis. AB - The separation of primary reproductive and secondary reproductive roles based on the differentiation of alate adults and neotenic reproductives is the most prominent characteristic of termites. To clarify the mechanism underlying this differentiation, we sequenced the transcriptomes of alate adults (ARs), brachypterous neotenics (BNs) and adultoid reproductives (ANs) from the last instar nymphs of Reticulitermes labralis. A total of 404,152,188 clean sequencing reads was obtained and 61,953 unigenes were assembled. Of the 54 identified cuticular protein (CP) genes of the reproductives, 22 were classified into the CPR family and 7 were classified into the CPG family. qRT-PCR analyses of the 6 CP genes revealed that the CP genes involved in exocuticle sclerotization were highly expressed in the ARs and RR-1 involved in soft endocuticle was highly expressed in the ARs and ANs. These results suggest that the alate adults might increase cuticular component deposition to adapt to new or changing environments and that the development of reproductive individuals into primary or secondary reproductives is controlled by the expression of cuticular protein genes involved in the hardening of the exocuticle. In addition, the AN caste is a transitional type between the BN and AR castes in the process of evolution. PMID- 27690210 TI - A systematic review of trial registration and selective outcome reporting in psychotherapy randomized controlled trials. AB - OBJECTIVE: Selective outcome reporting poses serious implications on our evidence base for best practice. The extent to which selective outcome reporting and trial registration occurs in the wider psychotherapy literature needs to be investigated. METHOD: Randomized controlled psychotherapy trials published between 2010 and 2014 were selected from the five highest impact factor journals in clinical psychology that publish clinical trials. Data on primary and secondary outcomes, funding, and participant numbers were extracted from the article and registry and compared. RESULTS: From 112 trials, 67 (59.8%) were registered, 27 (24.1%) were prospectively registered, and only 13 (11.6%) were correctly registered and reported. Seven of these 13 trials showed evidence of selective outcome reporting, of which four had discrepancies favoring significant outcomes. One of the remaining six trials changed their primary outcomes during participant enrollment. Overall, only five (4.5%) trials were free from selective outcome reporting. Three of these five trials had more than a 10% change between planned and achieved sample size. Funding was not associated with correct registration or reporting. CONCLUSIONS: The proportion of psychotherapy randomized controlled trials correctly registered and transparently reported is poor. Psychologists should consider the impact these results have on public confidence in reported outcomes. PMID- 27690211 TI - Self-Assembly and Conformational Changes of Hydrophobin Classes at the Air-Water Interface. AB - We use surface-specific vibrational sum-frequency generation spectroscopy (VSFG) to study the structure and self-assembling mechanism of the class I hydrophobin SC3 from Schizophyllum commune and the class II hydrophobin HFBI from Trichoderma reesei. We find that both hydrophobins readily accumulate at the water-air interface and form rigid, highly ordered protein films that give rise to prominent VSFG signals. We identify several resonances that are associated with beta-sheet structures and assign them to the central beta-barrel core present in both proteins. Differences between the hydrophobin classes are observed in their interfacial self-assembly. For HFBI, we observe no changes in conformation upon adsorption to the water surface. For SC3, we observe an increase in beta-sheet specific signals that supports a surface-driven self-assembly mechanism in which the central beta-barrel remains intact and stacks into a larger-scale architecture, amyloid-like rodlets. PMID- 27690212 TI - DNA Polymerase-Directed Hairpin Assembly for Targeted Drug Delivery and Amplified Biosensing. AB - Due to the predictable conformation and programmable Watson-Crick base-pairing interactions, DNA has proven to be an attractive material to construct various nanostructures. Herein, we demonstrate a simple model of DNA polymerase-directed hairpin assembly (PDHA) to construct DNA nanoassemblies for versatile applications in biomedicine and biosensing. The system consists of only two hairpins, an initiator and a DNA polymerase. Upon addition of aptamer-linked initiator, the inert stems of the two hairpins are activated alternately under the direction of DNA polymerase, which thus grows into aptamer-tethered DNA nanoassemblies (AptNAs). Moreover, through incorporating fluorophores and drug loading sites into the AptNAs, we have constructed multifunctional DNA nanoassemblies for targeted cancer therapy with high drug payloads and good biocompatibility. Interestingly, using the as-prepared AptNAs as building blocks, DNA nanohydrogels are self-assembled after centrifugation driven by liquid crystallization and dense packaging of DNA duplexes. Taking advantage of easy preparation and high loading capacity, the PDHAs are readily extended to the fabrication of a label-free biosensing platform, achieving amplified electrochemical detection of microRNA-21 (miR-21) with a detection limit as low as 0.75 fM and a dynamic range of 8 orders of magnitude. This biosensor also demonstrates excellent specificity to discriminate the target miR-21 from the control microRNAs and even the one-base mismatched one and further performs well in analyzing miR-21 in MCF-7 tumor cells.

PMID- 27690214 TI - Low Pretreatment Acoustic Radiation Force Impulse Imaging (ARFI) Values Predict Sustained Virological Response in Antiviral Hepatitis C Virus (HCV) Therapy. AB - BACKGROUND Non-invasive procedures such as acoustic radiation force impulse imaging (ARFI) shear-wave elastography are currently used for the assessment of liver fibrosis. In the course of chronic hepatitis C, significant liver fibrosis or cirrhosis develops in approximately 25% of patients, which is a negative predictor of antiviral treatment response. Cirrhosis can be prevented by successful virus elimination. In this prospective study, a pretreatment ARFI cutoff value of 1.5 m/s was evaluated in relation to sustained virological response to anti-HCV therapy. MATERIAL AND METHODS In 23 patients with chronic hepatitis C, liver stiffness was examined with ARFI at defined times before and under antiviral triple therapy (peginterferon, ribavirin in combination with a first-generation protease inhibitor, and telaprevir or boceprevir). Patients were stratified into 2 groups based on pretreatment ARFI values (<1.5 m/s and >=1.5 m/s) for the assessment of virological response. RESULTS The liver stiffness at baseline for all patients was 1.57+/-0.79 m/s (ARFI median +/- standard deviation; margin: 0.81 m/s to 3.45 m/s). At week 4 of triple therapy, patients with low pretreatment ARFI values had higher rates of HCV-RNA negativity (69% vs. 43%), reflecting an early rapid virological response (eRVR). Sustained virological response (SVR) was found in 75% (12/16) of patients with an ARFI value <1.5 m/s and only 57% (4/7) of patients with ARFI value >=1.5 m/s. CONCLUSIONS Patients with chronic hepatitis C and pretreatment ARFI <1.5 m/s showed earlier virus elimination and better response to treatment. PMID- 27690215 TI - The nullifying experience of self-objectification: The development and psychometric evaluation of the Self-Objectification Scale. AB - Self-objectification is a process or state in which an individual loses his/her sense of subjectivity. Although several measures assess self-objectification as representing self-perception based on sexual and bodily appearance, there is a need for a measure assessing self-objectification as reflecting dehumanization. This study aims to evaluate the psychometric properties of a new measure, the Self-Objectification Scale (SOS). In Study 1, the SOS was administered to 373 students. In Study 2, the SOS was administered to 300 female students along with a battery of questionnaires, including the Experience of Shame Scale (ESS) and the Objectified Body Consciousness Scale (OBC). In addition, participants were asked about their history of childhood maltreatment, via the Childhood Trauma Questionnaire (CTQ), as well as about their experience of sexual and/or physical assault, at any age. Two reliable SOS subscales emerged from Study 1: Invisibility and Lack of Autonomy. In Study 2, a confirmatory factor analysis confirmed the scale's underlying factor structure, which was obtained in Study 1. The two factors were significantly correlated with measures of shame and body objectification. Finally, individuals who reported childhood maltreatment, as well as those who reported sexual and/or physical assault at any age, had higher scores of Invisibility and Lack of Autonomy than those who did not have such experiences. The results of the present analyses suggest that the SOS has good psychometric properties, making it useful as an assessment tool in future research. PMID- 27690216 TI - Victimization and psychopathic features in a population-based sample of Finnish adolescents. AB - We examined different forms of victimization experiences in relation to psychopathic features and whether these associations differed in boys and girls among 4855 Finnish school adolescents aged 15-16 years. Psychopathic features were measured with the Antisocial Process Screening Device- Self Report (APSD SR). Victimization was assessed with questions about violent and abusive experiences across lifetime and within the last 12 months. Results from linear regression analysis showed that victimization was significantly associated with higher APSD-SR total scores, more strongly in girls than boys. Recent (12-month) victimization showed significance in the relationship between victimization and psychopathic features; especially recent sexual abuse and parental corporal punishment were strong determinants of higher APSD-SR total scores. The present study demonstrates novel findings on how severe victimization experiences relate to psychopathic features in community youth, especially in girls. The findings underscore the need for comprehensive evaluation of victimization experiences when psychopathic features are present in youth. PMID- 27690217 TI - The p53 status can influence the role of Sam68 in tumorigenesis. AB - The expression and activities of RNA binding proteins are frequently dysregulated in human cancer. Their roles, however, appears to be complex, with reports indicating both pro-tumorigenic and tumor suppressive functions. Here we show, using two classical mouse cancer models, that the role of KH-type RNA binding protein, Sam68, in tumor development can be influenced by the status of the p53 tumor suppressor. We demonstrate that in mice expressing wild type p53, Sam68 deficiency resulted in a higher incidence and malignancy of carcinogen-induced tumors, suggesting a tumor suppressive role for Sam68. In marked contrast, Sam68 haploinsufficiency significantly delayed the onset of tumors in mice lacking p53 and prolonged their survival, indicating that Sam68 accelerates the development of p53-deficient tumors. These findings provide considerable insight into a previously unknown relationship between Sam68 and the p53 tumor suppressor in tumorigenesis. PMID- 27690218 TI - Prognostic significance of BRCA mutations in ovarian cancer: an updated systematic review with meta-analysis. AB - There is no consensus on the syntheses concerning the impact of BRCA mutation on ovarian cancer survival. A systematic review and meta-analysis of observational studies was conducted that evaluated the impact of BRCA mutations on the survival outcomes of patients with ovarian cancer. The primary outcome measure was overall survival (OS) and secondary outcome was progression-free survival (PFS). We presented data with hazard ratios (HRs) and 95% confidence interval (CI) and pooled them using the random-effects models. From 2,624 unique records, 34 eligible studies including 18,396 patients were identified. BRCA1/2 mutations demonstrated both OS and PFS benefits in patients with ovarian cancer (OS: HR = 0.67, 95% CI, 0.57 to 0.78, I2 = 76.5%, P <0.001; PFS: HR = 0.62, 95% CI, 0.53 to 0.73, I2 = 18.1%, P = 0.261). For BRCA1 mutation carriers, the HRs for OS and PFS benefits were 0.73 (95% CI, 0.63 to 0.86) and 0.68 (95% CI, 0.52 to 0.89), respectively. For BRCA2 mutation carriers, the HRs for OS and PFS benefits were 0.57 (95% CI, 0.45 to 0.73) and 0.48 (95% CI, 0.30 to 0.75), respectively. The results of subgroup analyses for OS stratified by study quality, tumor stage, study design, sample size, number of research center, duration of follow-up, baseline characteristics adjusted and tumor histology were mostly constant across BRCA1/2, BRCA1 and BRCA2 mutation subtypes. In summary, for patients with ovarian cancer, BRCA mutations were associated with improved OS and PFS. Further large scale prospective cohort studies should be conducted to test its benefits in specific patients.

AB - Radiotherapy is commonly used to treat a variety of solid tumors but improvements in the therapeutic ratio are sorely needed. The aim of this study was to assess the Chk1 kinase inhibitor, MK-8776, for its ability to radiosensitize human tumor cells. Cells derived from NSCLC and HNSCC cancers were tested for radiosensitization by MK-8776. The ability of MK-8776 to abrogate the radiation induced G2 block was determined using flow cytometry. Effects on repair of radiation-induced DNA double strand breaks (DSBs) were determined on the basis of rad51, gamma-H2AX and 53BP1 foci. Clonogenic survival analyses indicated that MK 8776 radiosensitized p53-defective tumor cells but not lines with wild-type p53. Abrogation of the G2 block was evident in both p53-defective cells and p53 wild type lines indicating no correlation with radiosensitization. However, only p53 defective cells entered mitosis harboring unrepaired DSBs. MK-8776 appeared to inhibit repair of radiation-induced DSBs at early times after irradiation. A comparison of MK-8776 to the wee1 inhibitor, MK-1775, suggested both similarities and differences in their activities. In conclusion, MK-8776 radiosensitizes tumor cells by mechanisms that include abrogation of the G2 block and inhibition of DSB repair. Our findings support the clinical evaluation of MK-8776 in combination with radiation. PMID- 27690220 TI - Vemurafenib-resistant BRAF-V600E-mutated melanoma is regressed by MEK-targeting drug trametinib, but not cobimetinib in a patient-derived orthotopic xenograft (PDOX) mouse model. AB - Melanoma is a recalcitrant disease. The present study used a patient-derived orthotopic xenograft (PDOX) model of melanoma to test sensitivity to three molecularly-targeted drugs and one standard chemotherapeutic. A BRAF-V600E-mutant melanoma obtained from the right chest wall of a patient was grown orthotopically in the right chest wall of nude mice to establish a PDOX model. Two weeks after implantation, 50 PDOX nude mice were divided into 5 groups: G1, control without treatment; G2, vemurafenib (VEM) (30 mg/kg); G3; temozolomide (TEM) (25 mg/kg); G4, trametinib (TRA) (0.3 mg/kg); and G5, cobimetinib (COB) (5 mg/kg). Each drug was administered orally, daily for 14 consecutive days. Tumor sizes were measured with calipers twice a week. On day 14 from initiation of treatment, TRA, an MEK inhibitor, was the only agent of the 4 tested that caused tumor regression (P < 0.001 at day 14). In contrast, another MEK inhibitor, COB, could slow but not arrest growth or cause regression of the melanoma. First-line therapy TEM could slow but not arrest tumor growth or cause regression. The patient in this study had a BRAF-V600E-mutant melanoma and would be considered to be a strong candidate for VEM as first-line therapy, since VEM targets this mutation. However, VEM was not effective. The PDOX model thus helped identify the very-high efficacy of TRA against the melanoma PDOX and is a promising drug for this patient. These results demonstrate the powerful precision of the PDOX model for cancer therapy, not achievable by genomic analysis alone. PMID- 27690221 TI - RAB22A overexpression promotes the tumor growth of melanoma. AB - Malignant melanoma is the most aggressive type of skin cancer. RAB22A, a member of RAS oncogene family, has been found to be significantly upregulated in multiple human cancers. In the present study, we found that RAB22A mRNA expression was significantly upregulated in melanoma tissues (including 60 primary melanomas and 84 metastatic melanomas) compared to benign nevi (n = 20), which were significantly higher in metastatic melanoma tissues than primary tissues. Immunohistochemistry data further showed that the positive immunoreactivity of RAB22A was detected in 66% (95/144) melanoma tissues, but not in benign nevi. Moreover, high expression of RAB22A was significantly associated with advanced clinical stage in melanoma. Furthermore, patients with high RAB22A expression had shorter overall survival compared those with low expression of RAB22A. In-vitro study showed that RAB22A was also upregulated in melanoma cell lines WM35, A375, WM451, and SK-MEL-1, when compared with the normal melanocyte HM cells. Knockdown of RAB22A significantly reduced the proliferation, migration and invasion of melanoma A375 cells, while overexpression of RAB22A significantly promoted these malignant phenotypes. In addition, RAB22A was found to be a target of miR-203, a tumor suppressive miRNA in melanoma. Besides, miR-203 was downregulated in melanoma tissues and cell lines, when compared with benign nevi and HM cells, respectively. Taken these findings together, our study could validate an oncogenic role of RAB22A in melanoma, suggesting that RAB22A may be a potential therapeutic target for melanoma. PMID- 27690222 TI - Identification of Anthropogenic CO2 Using Triple Oxygen and Clumped Isotopes. AB - Quantification of contributions from various sources of CO2 is important for understanding the atmospheric CO2 budget. Considering the number and diversity of sources and sinks, the widely used proxies such as concentration and conventional isotopic compositions (delta13C and delta18O) are not always sufficient to fully constrain the CO2 budget. Additional constraints may help in understanding the mechanisms of CO2 production and consumption. The anomaly in triple oxygen isotopes or 17O excess (denoted by Delta17O) and molecules containing two rare isotopes, called clumped isotopes, are two recently developed tracers with potentials to independently constrain some important processes that regulate CO2 in the atmosphere. The clumped isotope for CO2, denoted by Delta47, is the excess of 13C16O18O over a random distribution of isotopes in a CO2 molecule. We measured the concentrations of delta13C, delta18O, Delta17O, and Delta47 in air CO2 samples collected from the Hsuehshan tunnel (length: 12.9 km), and applied linear and polynomial regressions to obtain the fossil fuel end-members for all these isotope proxies. The other end-members, the values of all these proxies for background air CO2, are either assumed or taken as the values obtained over the tunnel and ocean. The fossil fuel (anthropogenic) CO2 end-member values for delta13C, delta18O, Delta17O, and Delta47 are estimated using the two component mixing approach: the derived values are -26.76 +/- 0.250/00, 24.57 +/- 0.330/00, 0.219 +/- 0.0210/00, and 0.267 +/- 0.0360/00, respectively. These four major CO2 isotope tracers along with the concentration were used to estimate the anthropogenic contribution in the atmospheric CO2 in urban and suburban locations. We demonstrate that Delta17O and Delta47 have the potential to independently estimate anthropogenic contribution, and the advantages of these two over the conventional isotope proxies are discussed. PMID- 27690223 TI - Temporal proteomic analysis of HIV infection reveals remodelling of the host phosphoproteome by lentiviral Vif variants. AB - Viruses manipulate host factors to enhance their replication and evade cellular restriction. We used multiplex tandem mass tag (TMT)-based whole cell proteomics to perform a comprehensive time course analysis of >6500 viral and cellular proteins during HIV infection. To enable specific functional predictions, we categorized cellular proteins regulated by HIV according to their patterns of temporal expression. We focussed on proteins depleted with similar kinetics to APOBEC3C, and found the viral accessory protein Vif to be necessary and sufficient for CUL5-dependent proteasomal degradation of all members of the B56 family of regulatory subunits of the key cellular phosphatase PP2A (PPP2R5A-E). Quantitative phosphoproteomic analysis of HIV-infected cells confirmed Vif dependent hyperphosphorylation of >200 cellular proteins, particularly substrates of the aurora kinases. The ability of Vif to target PPP2R5 subunits is found in primate and non-primate lentiviral lineages, and remodeling of the cellular phosphoproteome is therefore a second ancient and conserved Vif function. PMID- 27690224 TI - Critical roles of mTOR Complex 1 and 2 for T follicular helper cell differentiation and germinal center responses. AB - T follicular helper (Tfh) cells play critical roles for germinal center responses and effective humoral immunity. We report here that mTOR in CD4 T cells is essential for Tfh differentiation. In Mtorf/f-Cd4Cre mice, both constitutive and inducible Tfh differentiation is severely impaired, leading to defective germinal center B cell formation and antibody production. Moreover, both mTORC1 and mTORC2 contribute to Tfh and GC B cell development but may do so via distinct mechanisms. mTORC1 mainly promotes CD4 T cell proliferation to reach the cell divisions necessary for Tfh differentiation, while Rictor/mTORC2 regulates Tfh differentiation by promoting Akt activation and TCF1 expression without grossly influencing T cell proliferation. Together, our results reveal crucial but distinct roles for mTORC1 and mTORC2 in CD4 T cells during Tfh differentiation and germinal center responses. PMID- 27690225 TI - Ongoing resolution of duplicate gene functions shapes the diversification of a metabolic network. AB - The evolutionary mechanisms leading to duplicate gene retention are well understood, but the long-term impacts of paralog differentiation on the regulation of metabolism remain underappreciated. Here we experimentally dissect the functions of two pairs of ancient paralogs of the GALactose sugar utilization network in two yeast species. We show that the Saccharomyces uvarum network is more active, even as over-induction is prevented by a second co-repressor that the model yeast Saccharomyces cerevisiae lacks. Surprisingly, removal of this repression system leads to a strong growth arrest, likely due to overly rapid galactose catabolism and metabolic overload. Alternative sugars, such as fructose, circumvent metabolic control systems and exacerbate this phenotype. We further show that S. cerevisiae experiences homologous metabolic constraints that are subtler due to how the paralogs have diversified. These results show how the functional differentiation of paralogs continues to shape regulatory network architectures and metabolic strategies long after initial preservation. PMID- 27690227 TI - Dynamic control of gene regulatory logic by seemingly redundant transcription factors. AB - Many transcription factors co-express with their homologs to regulate identical target genes, however the advantages of such redundancies remain elusive. Using single-cell imaging and microfluidics, we study the yeast general stress response transcription factor Msn2 and its seemingly redundant homolog Msn4. We find that gene regulation by these two factors is analogous to logic gate systems. Target genes with fast activation kinetics can be fully induced by either factor, behaving as an 'OR' gate. In contrast, target genes with slow activation kinetics behave as an 'AND' gate, requiring distinct contributions from both factors, upon transient stimulation. Furthermore, such genes become an 'OR' gate when the input duration is prolonged, suggesting that the logic gate scheme is not static but rather dependent on the input dynamics. Therefore, Msn2 and Msn4 enable a time based mode of combinatorial gene regulation that might be applicable to homologous transcription factors in other organisms. PMID- 27690226 TI - Fatty acid analogue N-arachidonoyl taurine restores function of IKs channels with diverse long QT mutations. AB - About 300 loss-of-function mutations in the IKs channel have been identified in patients with Long QT syndrome and cardiac arrhythmia. How specific mutations cause arrhythmia is largely unknown and there are no approved IKs channel activators for treatment of these arrhythmias. We find that several Long QT syndrome-associated IKs channel mutations shift channel voltage dependence and accelerate channel closing. Voltage-clamp fluorometry experiments and kinetic modeling suggest that similar mutation-induced alterations in IKs channel currents may be caused by different molecular mechanisms. Finally, we find that the fatty acid analogue N-arachidonoyl taurine restores channel gating of many different mutant channels, even though the mutations are in different domains of the IKs channel and affect the channel by different molecular mechanisms. N arachidonoyl taurine is therefore an interesting prototype compound that may inspire development of future IKs channel activators to treat Long QT syndrome caused by diverse IKs channel mutations. PMID- 27690228 TI - Impairment of Biofilm Formation by TiO2 Photocatalysis through Quorum Quenching. AB - The release of nanomaterials into the environment, due to their massive production and application today, has caused ecological and health safety concerns. Semiconductor photocatalysts like TiO2 exhibit cytotoxicity to bacterial cells when exposed to UV irradiation. However, information about their impacts on individual or group bacterial behaviors is limited. In this work, the biofilm formation of Escherichia coli K12 in the presence of TiO2 with and without UV irradiation was investigated and biofilm formation was found not to be affected under the sole application of TiO2 or UV irradiation. However, biofilm development was substantially delayed by TiO2 under UV irradiation, although no obvious cytotoxicity to cell growth was observed. The reactive oxygen species photogenerated by TiO2 were found to quench the autoinducer 2 (AI-2) signals secreted by E. coli K12. As a result, the initiation of quorum sensing for biofilm formation activated by AI-2 was restrained. The expressions of two biofilm-formation-related genes, motA and rcsB, were also suppressed. A dose of an AI-2 precursor, 4,5-dihydroxy-2,3-pentanedione, effectively restored the biofilm development. These results show that the photoexcited TiO2 could suppress biofilm formation through quenching AI-2 signals. This work may facilitate a better understanding about the ecological effects of increasingly released nanomaterials and provide implications for development of antifouling membranes. PMID- 27690229 TI - The Utilization of Rehabilitation in Patients with Hemophilia A in Taiwan: A Nationwide Population-Based Study. AB - INTRODUCTION: Rehabilitation plays an important role in the physical health of patients with hemophilia. However, comprehensive information regarding the utilization of rehabilitation for such patients remains scarce. AIM: This population-based study aimed to examine the characteristics, trends, and most important factors affecting rehabilitation usage in patients with hemophilia A using a nationwide database in Taiwan. METHODS: Data from 777 patients with hemophilia A who were registered in the National Health Insurance Research Database between 1998 and 2008 were analyzed using SAS 9.0. RESULTS: Musculoskeletal or nervous system-related surgical procedures and clotting factor VIII concentrate costs were identified as factors affecting rehabilitation usage; musculoskeletal or nervous system-related surgical procedures (odds ratio = 3.788; P < 0.001) were the most important predictor of whether a patient with hemophilia A would use rehabilitation services. Joint disorders, arthropathies, bone and cartilage disorders, intracranial hemorrhage, and brain trauma were common diagnoses during rehabilitation use. The costs of physical therapy (physiotherapy) comprised the majority (71.2%) of rehabilitation therapy categories. Increasingly, rehabilitation therapy was performed at physician clinics. The total rehabilitation costs were <0.1% of the total annual medical costs. CONCLUSION: Musculoskeletal or nervous system-related surgical procedures and increased use of clotting factor VIII concentrate affect the rehabilitation utilization of patients with hemophilia A the most. The findings in this study could help clinicians comprehensively understand the rehabilitation utilization of patients with hemophilia A. PMID- 27690230 TI - Turnover of 137Cs in 'soil-tree' system: An experience of measuring the isotope flows in a Siberian conifer forest. AB - Little attention has been paid to the uptake of 137Cs in natural forests under low levels of the isotope fallout when no immediate ecological danger presents. Here we present the extended assessments of the soil-to-plant and canopy-to litter flows of 137Cs recently evaluated in a native Siberian forested area. The area undergoes a typical after-fire long term succession, with light-conifer upper story being followed by undergrowth of Siberian fir and other dark-conifer species. The one-year-old needles of Siberian fir were found to accumulate the largest concentration of the isotope, 4.10 Bq/kg oven-dry weight during the first growth season, as compared with older needles that accumulated 4.67 Bq/kg oven dry weight in 2-3 years of growth. Based on these data an approach was developed that, hypothetically, can allow one to estimate the 137Cs activity concentration in soil solutions. Direct activity measurements in the soil solutions were not possible. The isotope activity in soil solutions was estimated to be 0.0061 0.0105 Bq/L. Based on the original data from the litter fall the annual flow of the isotope from the upper canopy to on-ground litter was found to be 0.42-0.84 Bq/m2. The amount of 137Cs that returns yearly back from canopy with falling litter was estimated to be 0.012-0.015% of the total soil isotope content. A combination of the estimations obtained in our study with the values of global 137Cs fallout allowed us to assess the ages (the time of formation) of horizons of the soils in the area. PMID- 27690231 TI - Genome Sequence Variability Predicts Drug Precautions and Withdrawals from the Market. AB - Despite substantial premarket efforts, a significant portion of approved drugs has been withdrawn from the market for safety reasons. The deleterious impact of nonsynonymous substitutions predicted by the SIFT algorithm on structure and function of drug-related proteins was evaluated for 2504 personal genomes. Both withdrawn (n = 154) and precautionary (Beers criteria (n = 90), and US FDA pharmacogenomic biomarkers (n = 96)) drugs showed significantly lower genomic deleteriousness scores (P < 0.001) compared to others (n = 752). Furthermore, the rates of drug withdrawals and precautions correlated significantly with the deleteriousness scores of the drugs (P < 0.01); this trend was confirmed for all drugs included in the withdrawal and precaution lists by the United Nations, European Medicines Agency, DrugBank, Beers criteria, and US FDA. Our findings suggest that the person-to-person genome sequence variability is a strong independent predictor of drug withdrawals and precautions. We propose novel measures of drug safety based on personal genome sequence analysis. PMID- 27690232 TI - Patient-Reported Vision-Related Quality-of-Life Differences between Primary Angle Closure Glaucoma and Primary Open-Angle Glaucoma. AB - PURPOSE: To investigate the different impacts on patient-reported vision-related quality of life (pVRQOL) outcomes in patients with primary angle-closure glaucoma(PACG) and primary open-angle glaucoma(POAG). METHODS: Prospective cross sectional study. PACG and POAG patients who had a best-corrected visual acuity(BCVA) in the better eye equal to or better than 20/60, intraocular pressure controlled at or below 25 mmHg and reliable visual field test were invited to participate. The control group included patients with BCVA in the better eye equal to or better than 20/60 and who did not have major eye disease. A validated Taiwanese version of the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25(T)) was performed to assess pVRQOL. The association between each domain of NEI VFQ-25(T) among 3 groups was determined using multivariable linear regression analysis. RESULTS: A total of 106 PACG, 186 POAG, and 95 controls were enrolled. In multivariable regression analysis of all three groups(PACG/POAG/controls), compared to POAG, PACG showed a weakly positive association with social functioning (R2 = 0.13, beta = 0.22, P = 0.04). PACG showed no significantly negative impact on pVRQOL compared to controls. Taking only glaucoma patients into consideration, PACG patients had a higher score on social functioning compared to POAG (R2 = 0.16, beta = 0.27, P = 0.01). The results of other domains of NEI VFQ-25(T) between the two groups did not differ significantly(p>0.05). CONCLUSIONS: In patients with controlled disease, the impact of PACG and POAG on most domains of NEI VFQ-25(T) were similar, except for better social functioning in PACG compared to POAG. PMID- 27690233 TI - Utility of Dexrazoxane for the Attenuation of Epirubicin-Induced Genetic Alterations in Mouse Germ Cells. AB - Dexrazoxane has been approved to treat anthracycline-induced cardiomyopathy and extravasation. However, the effect of dexrazoxane on epirubicin-induced genetic alterations in germ cells has not yet been reported. Thus, the aim of this study was to determine whether dexrazoxane modulates epirubicin-induced genetic damage in the germ cells of male mice. Our results show that dexrazoxane was not genotoxic at the tested doses. Furthermore, it protected mouse germ cells against epirubicin-induced genetic alterations as detected by the reduction in disomic and diploid sperm, spermatogonial chromosomal aberrations, and abnormal sperm heads. The attenuating effect of dexrazoxane was greater at higher dose, indicating a dose-dependent effect. Moreover, sperm motility and count were ameliorated by dexrazoxane pretreatment. Epirubicin induced marked biochemical changes characteristic of oxidative DNA damage including elevated 8-hydroxy-2' deoxyguanosine levels and reduction in reduced glutathione. Pretreatment of mice with dexrazoxane before epirubicin challenge restored these altered endpoints. We conclude that dexrazoxane may efficiently mitigate the epirubicin insult in male germ cells, and prevent the enhanced risk of abnormal reproductive outcomes and associated health risks. Thus, pretreating patients with dexrazoxane prior to epirubicin may efficiently preserve not only sperm quality but also prevent the transmission of genetic damage to future generations. PMID- 27690234 TI - Selective internal radiation therapy for liver metastases from colorectal cancer. AB - Liver metastases are often the dominant site of metastatic disease in colorectal cancer. Selective internal radiation therapy (SIRT) involves embolising radiolabeled spheres (SIR-Spheres) into the arterial supply of the liver. This review assesses the effectiveness and toxicity of SIRT in the treatment of metastatic colorectal cancer liver metastasis when given alone or with systemic or regional hepatic artery chemotherapy. We reviewed only randomised controlled trials comparing SIRT and chemotherapy (systemic and/or regional) with chemotherapy alone, or comparing SIRT alone with best supportive care. Only four randomized trials were identified. Due to heterogeneity of the patients and treatments received it was not possible to perform a formal meta-analysis, therefore this is a descriptive analysis only. All studies included patients with either liver only or liver dominant metastatic colorectal cancer. Two trials compared SIRT alone and SIRT with chemotherapy first line. The first with only 21 patients revealed a significant improvement in PFS and median survival with SIRT. The larger second study SIRFLOX of 530 patients comparing SIRT and current standard first line FOLFOX chemotherapy (+/- bevacizumab) with standard FOLFOX+/ bevacizumab alone. There was no improvement in overall PFS with addition of SIRT. In chemotherapy refractory patients SIRT and systemic chemotherapy (fluorouracil) improved progression free survival but not overall survival. A final study (63 patients) compared SIRT and regional chemotherapy (floxuridine) with regional chemotherapy alone in first line showed no significant difference in progression free survival and median survival. There remains a lack of evidence that SIRT improves survival or quality of life in patients with metastatic colorectal cancer. The overall survival results from SIRFLOX combined with FOXFIRE and FOXFIRE Global are awaited. PMID- 27690236 TI - Specific directions of ultrasound propagation in double potassium tungstates for light modulation. AB - Acousto-optical characteristics of double potassium tungstates are analyzed and specific directions for light modulation are found. First, an important subgroup of elasto-optic coefficients of KYb(WO4)2 and KLu(WO4)2 crystals are calculated with use of experimental data. It is revealed that with proper choice of ultrasound direction the acousto-optical figure-of-merit approximately 2 times exceeds the maximum value detected in previous experiments. Another unique direction is determined, which permits modulation of randomly polarized light. The elasto-optic characteristics of KYb(WO4)2 and KLu(WO4)2 crystals are compared to those of previously investigated materials of the same crystal group: KY(WO4)2, KGd(WO4)2. PMID- 27690235 TI - Dnmt3a Is a Haploinsufficient Tumor Suppressor in CD8+ Peripheral T Cell Lymphoma. AB - DNA methyltransferase 3A (DNMT3A) is an enzyme involved in DNA methylation that is frequently mutated in human hematologic malignancies. We have previously shown that inactivation of Dnmt3a in hematopoietic cells results in chronic lymphocytic leukemia in mice. Here we show that 12% of Dnmt3a-deficient mice develop CD8+ mature peripheral T cell lymphomas (PTCL) and 29% of mice are affected by both diseases. 10% of Dnmt3a+/- mice develop lymphomas, suggesting that Dnmt3a is a haploinsufficient tumor suppressor in PTCL. DNA methylation was deregulated genome-wide with 10-fold more hypo- than hypermethylated promoters and enhancers, demonstrating that hypomethylation is a major event in the development of PTCL. Hypomethylated promoters were enriched for binding sites of transcription factors AML1, NF-kappaB and OCT1, implying the transcription factors potential involvement in Dnmt3a-associated methylation. Whereas 71 hypomethylated genes showed an increased expression in PTCL, only 3 hypermethylated genes were silenced, suggesting that cancer-specific hypomethylation has broader effects on the transcriptome of cancer cells than hypermethylation. Interestingly, transcriptomes of Dnmt3a+/- and Dnmt3aDelta/Delta lymphomas were largely conserved and significantly overlapped with those of human tumors. Importantly, we observed downregulation of tumor suppressor p53 in Dnmt3a+/- and Dnmt3aDelta/Delta lymphomas as well as in pre-tumor thymocytes from 9 months old but not 6 weeks old Dnmt3a+/- tumor-free mice, suggesting that p53 downregulation is chronologically an intermediate event in tumorigenesis. Decrease in p53 is likely an important event in tumorigenesis because its overexpression inhibited proliferation in mouse PTCL cell lines, suggesting that low levels of p53 are important for tumor maintenance. Altogether, our data link the haploinsufficient tumor suppressor function of Dnmt3a in the prevention of mouse mature CD8+ PTCL indirectly to a bona fide tumor suppressor of T cell malignancies p53. PMID- 27690237 TI - Acoustical spinner tweezers with nonparaxial Hermite-Gaussian acoustical-sheets and particle dynamics. AB - Hermite-Gaussian (HGl) acoustical-sheets are introduced and their beamforming properties are examined. A general nonparaxial mathematical solution for the incident beam of any order l is derived based on the angular spectrum decomposition in plane waves. The beam-shape coefficients characterizing the incident beam in cylindrical coordinates are expressed in an integral form and computed using the standard numerical integration procedure based on the trapezoidal rule. The analysis is further extended to calculate the longitudinal and transverse acoustic radiation force functions as well as the axial radiation torque function for a viscous fluid cylindrical cross-section submerged in a non viscous fluid and located arbitrarily in space in the field of the HGl beams in the Rayleigh and resonance (Mie) regimes. The numerical results show that the absorptive cylinder can be pulled, pushed, or manipulated and rotated around its center of mass when placed in the acoustical field of a HGl beam. Clockwise or anticlockwise rotations can arise depending on the cylinder position in the acoustic field. Moreover, a particle dynamics analysis is established based on Newton's second law of motion during which the trajectories of the cylinder subjected to the acoustical field of forces are computed. The results can find potential applications in particle manipulation and handling, acoustical microscopy imaging, and surface acoustic waves to name a few examples. PMID- 27690239 TI - Synthesis and characterization of biocompatible antimicrobial N-halamine functionalized titanium dioxide core-shell nanoparticles. AB - As one of the most powerful biocides, N-halamine based antimicrobial materials have attracted much interest due to their non-toxicity, rechargeability, and rapid inactivation against a broad range of microorganisms. In this study, novel titanium dioxide-ADMH core-shell nanoparticles [TiO2@poly (ADMH-co-MMA) NPs] were prepared via miniemulsion polymerization using 3-allyl-5,5-dimethylhydantoin (ADMH) and methyl methacrylate (MMA) with nano-TiO2. The produced nanoparticles were characterized by FT-IR, TEM, TGA, and XPS. The UV stability of N-halamine nanoparticles has been improved with the addition of titanium dioxide. After chlorination treatment by sodium hypochlorite, biocidal efficacies of the chlorinated nanoparticles against S. aureus (ATCC 6538) and E. coli O157:H7 (ATCC 43895) were determined. The nanoparticles showed excellent antimicrobial properties against bacteria within brief contact time. In addition, in vitro cell cytocompatibility tests showed that the antibacterial nanoparticles had good biocompatibility. PMID- 27690238 TI - CXCL1-Mediated Interaction of Cancer Cells with Tumor-Associated Macrophages and Cancer-Associated Fibroblasts Promotes Tumor Progression in Human Bladder Cancer. AB - Tumor-associated macrophages (TAMs) and cancer-associated fibroblasts (CAFs) are reported to be associated with poor prognosis, depending on their pro-tumoral roles. Current knowledge of TAMs and CAFs in the tumor microenvironment of urothelial cancer of the bladder (UCB) is limited. Therefore, we investigated the paracrine effect induced by TAMs and CAFs in the tumor microenvironment of human UCB. For this, we first carried out immunohistochemical analysis for CXCL1, CD204 (TAM marker), alphaSMA (CAF marker), E-cadherin, and MMP2 using 155 UBC tissue samples. Next, CXCL1-overexpressing clones of THP-1-derived TAMs and NIH3T3 derived CAFs were developed by lentiviral vector infection. The immunohistochemical study showed high CXCL1 levels in UCB cells to be associated with enhanced recruitment of TAMs/CAFs, higher metastatic potential, and poor prognosis. Three-dimensional (3D) co-culture of UCB cells and TAMs/CAFs suggested that CXCL1 production in TAMs/CAFs play an important role in cell-to-cell adhesion and interaction among cancer cells and these stromal cells. CXCL1 expressing TAMs/CAFs enhanced tumor growth of subcutaneous UCB tumors in nude mice when injected together. In addition, an experiment using the orthotopic bladder cancer model revealed that CXCL1 production in TAMs/CAFs supported tumor implantation into the murine bladder wall and UCB growth when injected together, which was confirmed by clinical data of patients with bladder cancer. Thus, CXCL1 signaling in the tumor microenvironment is highly responsible for repeated intravesical recurrence, disease progression, and drug resistance through enhanced invasion ability. In conclusion, disrupting CXCL1 signaling to dysregulate this chemokine is a promising therapeutic approach for human UCB. PMID- 27690241 TI - In vitro drug release and percutaneous behavior of poloxamer-based hydrogel formulation containing traditional Chinese medicine. AB - For the treatment of atopic dermatitis (AD), we have developed a transdermal functionalized textile therapy based on thermosensitive poloxamer 407 (P407) hydrogel containing a traditional Chinese herbal medicine. This study aims to investigate the effects of various formulation variables of P407/carboxymethyl cellulose sodium (P407/CMCs) composite hydrogel on the release of Cortex Moutan (CM) extract. Concentrations of P407 and CMCs showed significant influence on the release due to alteration of bulk viscosity of the system. An increase in pH values of release medium was found to appreciably impede the release of polar drug (CM) due to ionization. Elevated temperatures were also shown to facilitate the drug release. Moreover, the diffusional release behavior of CM from P407/CMCs composite hydrogel was found to follow the first-order kinetic model. Additionally, transdermal studies showed that permeability of the drug through the skin can be enhanced with addition of CMCs in the hydrogel formulation.

AB - Cerasome is a freshly developped bilayer vehicle that resemble traditional liposome but has higher mophorlogical stability. In this study, a novel redox responsive cerasome (RRC) was developed for tumor-targeting drug delivery. The cerasome-forming lipid (CFL) that comprise a cleavable disulfide bond as connector unit of the triethoxysilyl head and the hydrophobic alkyl double chain was synthesized and subsequently used to prepare cerasome through ethanol injection method. RRC that has liposome-resembling lipid bilayer structure was proved being outstanding at drug loading capacity as well as morphological stability as compared to conventional liposomes. In addition, in vitro drug release tests of DOX/RRCs showed a redox-responsive drug release profile: accelerated DOX releasing compared to reduction-insensitive cerasomes (RICs) in the presence of 10mM of GSH. Under the same condition, the reduction sensibility of RRC was further proved by increased hydrodynamic diameter and destroying of integrity from DLS and SEM results. RRC showed non-toxic to human embryonic kidney 293 cells, indicating that this material has good biocompatibility. On the other hand, DOX/RRCs showed a resemble IC50 (half inhibitory concentration) value to that of free DOX to human hepatoma SMMC-7721 cells and breast cancer MCF-7 cells. IC50 values at 48h were found to decrease in the following order: DOX/RIC>DOX/RRC>DOX. Taken together, the RRC developped in this study is of great potential to be utilized as a promising platform for intracellular anticancer drug delivery. PMID- 27690242 TI - Biomimetic HDL nanoparticle mediated tumor targeted delivery of indocyanine green for enhanced photodynamic therapy. AB - Photodynamic therapy has emerged as a promising strategy for cancer treatment. To ensure the efficient delivery of a photosensitizer to tumor for anticancer effect, a safe and tumor-specific delivery system is highly desirable. Herein, we introduce a novel biomimetic nanoparticle named rHDL/ICG (rHDL/I), by loading amphiphilic near-infrared (NIR) fluorescent dye indocyanine green (ICG) into reconstituted high density lipoproteins (rHDL). In this system, rHDL can mediate photoprotection effect and receptor-guided tumor-targeting transportation of cargos into cells. Upon NIR irradiation, ICG can generate fluorescent imaging signals for diagnosis and monitoring therapeutic activity, and produce singlet oxygen to trigger photodynamic therapy (PDT). Our studies demonstrated that rHDL/I exhibited excellent size and fluorescence stability, light-triggered controlled release feature, and neglectable hemolytic activity. It also showed equivalent NIR response compared to free ICG under laser irradiation. Importantly, the fluorescent signal of ICG loaded in rHDL/I could be visualized subcellularly in vitro and exhibited metabolic distribution in vivo, presenting superior tumor targeting and internalization. This NIR-triggered image-guided nanoparticle produced outstanding therapeutic outcomes against cancer cells, demonstrating great potential of biomimetic delivery vehicles in future clinical practice. PMID- 27690243 TI - Zeta-potential data reliability of gold nanoparticle biomolecular conjugates and its application in sensitive quantification of surface absorbed protein. AB - Zeta potentials (ZP) of gold nanoparticle bioconjugates (AuNP-bios) provide important information on surface charge that is critical for many applications including drug delivery, biosensing, and cell imaging. The ZP measurements (ZPMs) are conducted under an alternative electrical field at a high frequency under laser irradiation, which may strongly affect the status of surface coating of AuNP-bios and generate unreliable data. In this study, we systemically evaluated the ZP data reliability (ZPDR) of citrate-, thiolated single stranded DNA-, and protein-coated AuNPs mainly according to the consistence of ZPs in the repeated ZPMs and the changes of the hydrodynamic size before and after the ZPMs. We found that the ZPDR was highly dependent on both buffer conditions and surface modifications. Overall, the higher ionic strength of the buffer and the lower affinity of surface bounders were related with the worse ZPDR. The ZPDR of citrate-coated AuNP was good in water, but bad in 10mM phosphate buffer (PB), showing substantially decrease of the absolute ZP values after each measurement, probably due to the electrical field facilitated adsorption of negatively charged phosphate ions on AuNPs. The significant desorption of DNAs from AuNP was observed in the PB containing medium concentration of NaCl, but not in PB. The excellent ZPDR of bovine serum albumin (BSA)-coated AuNP was observed at high salt concentrations and low surface coverage, enabling ZPM as an ultra-sensitive tool for protein quantification on the surface of AuNPs with a single molecule resolution. PMID- 27690244 TI - Surface chemistry from wettability and charge for the control of mesenchymal stem cell fate through self-assembled monolayers. AB - Self-assembled monolayers (SAMs) of alkanethiols on gold are highly controllable model substrates and have been employed to mimic the extracellular matrix for cell-related studies. This study aims to systematically explore how surface chemistry influences the adhesion, morphology, proliferation and osteogenic differentiation of mouse mesenchymal stem cells (mMSCs) using various functional groups (-OEG, -CH3, -PO3H2, -OH, -NH2 and -COOH). Surface analysis demonstrated that these functional groups produced a wide range of wettability and charge: OEG (hydrophilic and moderate iso-electric point (IEP)), -CH3 (strongly hydrophobic and low IEP), -PO3H2 (moderate wettability and low IEP), -OH (hydrophilic and moderate IEP), -NH2 (moderate wettability and high IEP) and COOH (hydrophilic and low IEP). In terms of cell responses, the effect of wettability may be more influential than charge for these groups. Moreover, compared to -OEG and -CH3 groups, -PO3H2, -OH, -NH2 and -COOH functionalities tended to promote not only cell adhesion, proliferation and osteogenic differentiation but also the expression of alphav and beta1 integrins. This finding indicates that the surface chemistry may guide mMSC activities through alphav and beta1 integrin signaling pathways. Model surfaces with controllable chemistry may provide insight into biological responses to substrate surfaces that would be useful for the design of biomaterial surfaces.

AB - More engaging teaching and learning strategies are needed to teach research related courses to pre-registration nursing students. Team-based learning was implemented within a second year pre-registration nursing evidence-informed decision making course. Results from a questionnaire survey indicated that 70% believed team-based learning was appropriate for the course, 60% that it was an effective and motivating learning strategy, and 54% recommended using team-based learning in other courses. The results from ten student interviews illustrated the positive way in which team-based learning was perceived, and how the students thought it contributed to their learning. Test results were improved with an increase in the numbers of students achieving 70% or higher; and higher scores for students in the lowest quartile. Team-based learning was shown to be an effective strategy that preserved the benefits of small group teaching with large student groups. PMID- 27690245 TI - Biocompatible electrically conductive nanofibers from inorganic-organic shape memory polymers. AB - A porous shape memory scaffold with both biomimetic structures and electrical conductivity properties is highly promising for nerve tissue engineering applications. In this study, a new shape memory polyurethane polymer which consists of inorganic polydimethylsiloxane (PDMS) segments with organic poly(epsilon-caprolactone) (PCL) segments was synthesized. Based on this poly(PCL/PDMS urethane), a series of electrically conductive nanofibers were electrospun by incorporating different amounts of carbon-black. Our results showed that after adding carbon black into nanofibers, the fiber diameters increased from 399+/-76 to 619+/-138nm, the crystallinity decreased from 33 to 25% and the resistivity reduced from 3.6 GOmega/mm to 1.8 kOmega/mm. Carbon black did not significantly influence the shape memory properties of the resulting nanofibers, and all the composite nanofibers exhibited decent shape recovery ratios of >90% and shape fixity ratios of >82% even after 5 thermo-mechanical cycles. PC12 cells were cultured on the shape memory nanofibers and the composite scaffolds showed good biocompatibility by promoting cell-cell interactions. Our study demonstrated that the poly(PCL/PDMS urethane)/carbon-black nanofibers with shape memory properties could be potentially used as smart 4-dimensional (4D) scaffolds for nerve tissue regeneration. PMID- 27690248 TI - Confocal Luminescence Lifetime Imaging with Variable Scan Velocity and Its Application to Oxygen Sensing. AB - The dependence of the luminescence lifetime on the probe environment is the basis of a range of sensing techniques. The major advantage of using the lifetime as the sensitive parameter is its independence on the probe concentration. However, the instrumentation for lifetime measurements is complex, generally requiring time-resolved excitation and detection. Here, we present a simple method for the measurement of luminescence lifetimes on the microsecond scale based on variable excitation time determined by the scanning velocity. The technique is implemented in a confocal laser scanning microscope (CLSM), thus allowing not only simple lifetime measurement but also phosphorescence lifetime imaging. Since the method exploits the spatiotemporal dependence of sample excitation in a CLSM, there is no need for a pulsed or modulated light source or for additional time-resolved detection. The method can be realized in a standard CLSM without any modifications. The principle is demonstrated on oxygen sensing by collisional quenching of an oxygen-sensitive ruthenium(II) complex.

PMID- 27690247 TI - Mathematical Modeling of the Transmission Dynamics of Clostridium difficile Infection and Colonization in Healthcare Settings: A Systematic Review. AB - BACKGROUND: We conducted a systematic review of mathematical models of transmission dynamic of Clostridium difficile infection (CDI) in healthcare settings, to provide an overview of existing models and their assessment of different CDI control strategies. METHODS: We searched MEDLINE, EMBASE and Web of Science up to February 3, 2016 for transmission-dynamic models of Clostridium difficile in healthcare settings. The models were compared based on their natural history representation of Clostridium difficile, which could include health states (S-E-A-I-R-D: Susceptible-Exposed-Asymptomatic-Infectious-Resistant Deceased) and the possibility to include healthcare workers and visitors (vectors of transmission). Effectiveness of interventions was compared using the relative reduction (compared to no intervention or current practice) in outcomes such as incidence of colonization, CDI, CDI recurrence, CDI mortality, and length of stay. RESULTS: Nine studies describing six different models met the inclusion criteria. Over time, the models have generally increased in complexity in terms of natural history and transmission dynamics and number/complexity of interventions/bundles of interventions examined. The models were categorized into four groups with respect to their natural history representation: S-A-I-R, S-E-A I, S-A-I, and S-E-A-I-R-D. Seven studies examined the impact of CDI control strategies. Interventions aimed at controlling the transmission, lowering CDI vulnerability and reducing the risk of recurrence/mortality were predicted to reduce CDI incidence by 3-49%, 5-43% and 5-29%, respectively. Bundles of interventions were predicted to reduce CDI incidence by 14-84%. CONCLUSIONS: Although CDI is a major public health problem, there are very few published transmission-dynamic models of Clostridium difficile. Published models vary substantially in the interventions examined, the outcome measures used and the representation of the natural history of Clostridium difficile, which make it difficult to synthesize results and provide a clear picture of optimal intervention strategies. Future modeling efforts should pay specific attention to calibration, structural uncertainties, and transparent reporting practices. PMID- 27690250 TI - Validity of the Stokes-Einstein relation in liquids: simple rules from the excess entropy. AB - It is becoming common practice to consider that the Stokes-Einstein relation D/T~ eta -1 usually works for liquids above their melting temperatures although there is also experimental evidence for its failure. Here we investigate numerically this commonly-invoked assumption for simple liquid metals as well as for their liquid alloys. Using ab initio molecular dynamics simulations we show how entropy scaling relationships developed by Rosenfeld can be used to predict the conditions for the validity of the Stokes-Einstein relation in the liquid phase. Specifically, we demonstrate the Stokes-Einstein relation may break down in the liquid phase of some liquid alloys mainly due to the presence of local structural ordering as evidenced in their partial two-body excess entropies. Our findings shed new light on the understanding of transport properties of liquid materials and will trigger more experimental and theoretical studies since excess entropy and its two-body approximation are readily obtainable from standard experiments and simulations. PMID- 27690251 TI - Subependymal giant cell astrocytoma in a genetically negative tuberous sclerosis complex adult: Case report. AB - INTRODUCTION: The well-described entity of Subependymal Giant Cell Astrocytoma (SEGA) in the setting of Tuberous Sclerosis Complex (TSC) is profound in current literature. It has been described in children as well as adults with or without identifiable clinical presentations of tuberous sclerosis. To our knowledge there has not been any report of a negative genetic workup of Tuberous Sclerosis Complex in an adult patient presenting with an isolated SEGA. CASE REPORT: We present a case of a 25-year-old female with no medical history who presented to the emergency room for headaches. Further workup included gadolinium enhanced MRI of the brain which revealed a homogenously enhancing mass in the left lateral ventricle with eccentric calcification and resultant obstructive hydrocephalus. A left frontal craniotomy with an interhemispheric transcallosal approach was taken for complete removal of the mass. DISCUSSION: Final pathological diagnosis was SEGA with suggestive cell population, positive GFAP and positive synaptophysin. Genetic testing included TSC1 (MLPA, DNA Sequencing) and TSC2 (MLPA, DNA Sequencing), which were all negative. The panel did not identify mutations associated with Tuberous Sclerosis. CONCLUSION: Rare cases of isolated SEGA have been reported in patients who do not have typical features of tuberous sclerosis, and may represent minimal penetrance of the disease with an attenuated phenotype. Negative genetic testing, as demonstrated, can be seen in adults with isolated SEGA. With a negative genetic workup of TSC, regular follow up may still be necessary; however this may prove to be low yield for identifying any TSC features in the future. PMID- 27690252 TI - Octreotide: The IIH therapy beyond weight loss, carbonic anhydrase inhibitors, lumbar punctures and surgical/interventional treatments. AB - OBJECTIVE: Idiopathic intracranial hypertension (IIH) is characterized by elevated intracranial pressure without a space-occupying cerebral lesion, venous sinus thrombosis or hydrocephalus and with normally composited cerebrospinal fluid (CSF). Main symptoms are headache, sight disturbances and potential visual impairment. Weight loss, carbonic anhydrase inhibitors, lumbar punctures with CSF drain, CSF shunting, optic nerve sheath fenestration, and venous sinus stenting are common IIH therapies. Octreotide, a synthetic somatostatin analogue, also effectively suspends IIH symptoms. Here, treatment with octreotide on five so far inefficiently treated IIH patients is presented and discussed. METHODS: Five female patients with IIH and a history of failed therapy regimes were treated with octreotide, to be administered everyday subcutaneously for six months with identified doses high enough to suspend all clinical IIH symptoms. After tapering for two months, the further clinical course was to be monitored. RESULTS: All patients were IIH symptom-free under octreotide. After tapering, one patient remained IIH symptom-free; one patient became IIH symptom-free under intramuscular octreotide after failure of former therapy regimes; one patient became IIH symptom-free on low-dose carbonic anhydrase inhibitors; one patient had an allergic reaction and paused octreotide, after successful desensitization, tooth ache developed, forcing octreotide tapering; one patient had another shunt revision alleviating IIH symptoms. CONCLUSION: We confirmed that a) clinical IIH symptoms are suspended during octreotide exposure; b) 6-month administration can sustainably abolish IIH symptoms; c) desensitization is possible for octreotide allergy. When IIH symptoms reoccur after limited-time octreotide administration, re-application of formerly ineffective carbonic anhydrase inhibitors can suspend IIH symptoms. Intramuscular octreotide is a promising long-term therapy option.

AB - The HOMA index calculated for [2.2]paracyclophanes in the solid state reveals a slight decrease of aromaticity. Interactions between aromatic rings of [2.2]paracyclophane have been investigated using AIM and NCI analysis in both crystal and optimized [2.2]paracyclophane structures. AIM analysis showed that the C...C bond path between the two aromatic rings is present only in few [2.2]paracyclophanes. The NCI approach visualized the dispersion and repulsive interactions between the aromatic rings of every [2.2]paracyclophane. Combination of AIM and the NCI approach is necessary for determining and identifying nonbonded interactions in [2.2]paracyclophanes.

AB - Six new 16-membered macrolides with a rare branched octose unit, aldgamycins J-O (1-6), along with two known compounds, swalpamycin B (7) and chalcomycin (8), were isolated from Streptomyces sp. HK-2006-1. Their structures were determined by detailed spectroscopic and X-ray crystallographic analysis. Natural products containing branched sugar units are rare. Aldgaropyranose and decarboxylated aldgaropyranose are branched octoses, specifically aldgarose-type branched octose. Until now, only 11 compounds have been reported to contain an aldgarose type branched octose. The discovery of aldgamycins J-O (1-6) adds new members of this type of natural product. All the compounds (1-8) herein were tested for antimicrobial activities against Gram-positive Staphylococcus aureus 209P, Gram negative Escherichia coli ATCC0111, and two fungi, Candida albicans FIM709 and Aspergillus niger R330. Most of these compounds showed antibacterial activity against S. aureus. Their preliminary structure-activity relationships are proposed.

AB - We describe a novel C>T substitution at codon 53 of the HBB gene (HBB: c.161C>T). The proband was a transfusion-dependent beta-thalassemia major (beta-TM) patient. DNA was extracted and subsequently, DNA sequencing was done to detect the mutations on the HBB gene. Capillary zone electrophoresis (CZE) revealed the presence of an unknown peak. She inherited this mutation from her grandmother through her mother. This mutation exists in cis with the common beta0 mutation IVS-I-5 (G>C) (HBB: c.92+5G>C). The proband is homozygous for HBB: c.92+5G>C and needs monthly transfusions. On the other hand, her grandmother, mother and sister all possess this novel mutation cis with the heterozygous HBB: c.92+5G>C. They are carriers not thalassemic. This mutation produces the substitution beta53(D4)Ala->Val; HBB: c.161C>T, a new structural hemoglobin (Hb) variant. As this variant was identified in a Bengali family from Paschim Midnapore district of West Bengal, India, it has been designated as Hb Midnapore. This variant has now been reported to the HbVar database. PMID- 27690259 TI - Spaces and Places in the Lives of Urban Adolescents at Risk for Substance Misuse.

AB - INTRODUCTION: New frontiers in nanomedicine are moving towards the research of new biomaterials. Apoferritin (APO), is a uniform regular self-assemblies nano sized protein with excellent biocompatibility and a unique structure that affords it the ability to stabilize small active molecules in its inner core. Areas covered: APO can be loaded by applying a passive process (mainly used for ions and metals) or by a unique formulative approach based on disassemby/reassembly process. In this article, we aim to organize the experimental evidence provided by a number of studies on the loading, release and targeting. Attention is initially focused on the most investigated antineoplastic drug and contrast agents up to the most recent application in gene therapy. Expert opinion: Various preclinical studies have demonstrated that APO improved the potency and selectivity of some chemotherapeutics. However, in order to translate the use of APO into therapy, some issues must be solved, especially regarding the reproducibility of the loading protocol used, the optimization of nanocarrier characterization, detailed understanding of the final structure of loaded APO, and the real mechanism and timing of drug release. PMID- 27690261 TI - Development of Tetrachlorophthalimides as Liver X Receptor beta (LXRbeta) Selective Agonists. AB - Liver X receptor (LXR) agonists are candidates for the treatment of atherosclerosis via induction of ABCA1 (ATP-binding cassette A1) gene expression, which contributes to reverse cholesterol transport (RCT) and to cholesterol efflux from the liver and intestine. However, LXR agonists also induce genes involved in lipogenesis, such as SREBP-1c (sterol regulatory binding element protein 1c) and FAS (fatty acid synthase), thereby causing an undesirable increase in plasma and hepatic triglyceride (TG) levels. Recent studies indicate that LXRalpha contributes to lipogenesis in liver, and selective LXRbeta activation improves RCT in mice. Therefore, LXRbeta-selective agonists are promising candidates to improve atherosclerosis without increasing plasma or hepatic TG levels. However, the ligand-binding domains in the two LXR isoforms alpha/beta share high sequence identity, and few LXR ligands show subtype selectivity. In this study we identified a tetrachlorophthalimide analogue as an LXRbeta-selective agonist. Structural development led to (E)-4,5,6,7-tetrachloro 2-(2-styrylphenyl)isoindoline-1,3-dione (24 a), which shows potent and selective LXRbeta agonistic activity in reporter gene assays. In binding assays, compound 24 a bound to LXRbeta preferentially over LXRalpha. It also induced the expression of ABCA1 mRNA but not SREBP-1c mRNA in cells. Compound 24 a appears to be a promising lead compound for therapeutic agents to treat atherosclerosis without the side effects induced by LXRalpha/beta dual agonists. PMID- 27690263 TI - Metal Nanoparticle-Catalyzed Reduction Using Borohydride in Aqueous Media: A Kinetic Analysis of the Surface Reaction by Microfluidic SERS. AB - Hydrides are widely used in reduction reactions. In protic solvents, their hydrolysis generates molecular hydrogen as a second reducing agent. The competition between these two parallel reduction pathways has been overlooked so far since both typically yield the same product. We investigated the platinum catalyzed reduction of 4-nitrothiophenol to 4-aminothiophenol in aqueous sodium borohydride solution as a prominent model reaction, by using label-free SERS monitoring in a microfluidic reactor. Kinetic analysis revealed a strong pH dependence. Surprisingly, only at pH>13 the reduction is driven exclusively by sodium borohydride. This study demonstrates the potential of microfluidics-based kinetic SERS monitoring of heterogeneous catalysis in colloidal suspension. PMID- 27690262 TI - Detection of bone marrow changes related to estrogen withdrawal in rats with a tabletop stray-field NMR scanner. AB - PURPOSE: Osteoporosis is characterized by a decrease in bone mineral density (BMD). A preliminary stage of the disease is progressive bone marrow adiposity, caused by imbalance between osteogenesis and adipogenesis in the marrow. Detection of osteoporosis relies on the quantification of BMD with techniques such as dual-energy X-ray absorptiometry. This work aimed to detect bone marrow changes in an experimental model of osteopenia using a low-field tabletop NMR scanner. METHODS: An experiment was performed on 32 female rats, 3 months old, 16 of which were ovariectomized (OVX) and 16 were sham-operated (sham). The femur and tibia from both hind limbs were isolated and underwent ex vivo NMR scans at four time points after the OVX and sham operations. NMR scans were complemented by BMD measurements and histology. RESULTS: Significant changes in the bone marrow of ovariectomized rats, relative to sham operated rats, were observed after 3.5 and 4.5 months. Bone marrow adiposity was detected by significant changes in T1 and T2 relaxation times, and in the diffusion coefficient. CONCLUSIONS: This study suggests a potential detection of changes to the bone marrow using a tabletop NMR device. Clinical translation may facilitate screening, early detection of bone weakening as a result of estrogen withdrawal, and monitoring of treatment efficacy. Magn Reson Med 78:860-870, 2017.

AB - PURPOSE: To determine whether fat-signal-fraction (FF) map using a modified Dixon sequence could help differentiate benign from malignant bone lesions. MATERIALS AND METHODS: Spine magnetic resonance images (MRIs) of 120 consecutive patients were studied by using a 3T MRI with standard T1 -weighted image (T1 WI) and modified-Dixon sequence for FF measurement. There were three groups: a control group (n = 51) with normal vertebrae; a benign group (n = 40) with focal red marrow deposition, Schmorl's nodes, benign compression fracture, or Modic type 1 endplate degeneration; a malignant group (n = 29) with spinal malignancies. The following three parameters were measured on T1 WI and FF map by two radiologists independently: T1 signal intensity (SI), FF and T1 SI of normal disc (SI). Then, Lesion-to-disc ratio (LDR = SI of the lesion/SId ) and FF ratio of lesion and normal marrow were calculated. The mean values of the parameters were compared among the groups and Receiver Operating Characteristic (ROC) curves were analyzed. Then a logistic regression was performed. RESULTS: The FF (2.8%) and FF ratio (0.082) of malignancy were lower than benign lesions (P < 0.001). There was no difference in the LDR between malignancy and Schmorl's nodes (P = 0.795) or a benign compression fracture (P = 0.866). The areas under the ROC curves of FF and FF ratio were 93% and 87%, respectively, which were higher than those of the other parameters used for differentiation (P < 0.001). In logistic regression analyses, FF remained a significant variable that could be used to independently differentiate benign from malignant lesions, with an odds ratio of 1.9 (P < 0.001). CONCLUSION: The FF and FF ratio obtained from FF maps using modified Dixon sequence could be used to distinguish between benign and malignant causes of focal bone marrow abnormalities when difficulty in the qualitative interpretation of conventional MR images arises.

PMID- 27690266 TI - The shared and unique genetic relationship between mental well-being, depression and anxiety symptoms and cognitive function in healthy twins. AB - Alterations to cognitive function are often reported with depression and anxiety symptoms, yet few studies have examined the same associations with mental well being. This study examined the association between mental well-being, depression and anxiety symptoms and cognitive function in 1502 healthy adult monozygotic (MZ) and dizygotic (DZ) twins, and the shared/unique contribution of genetic (G) and environmental (E) variance. Using linear mixed models, mental well-being was positively associated (p < .01) with sustained attention (beta = 0.127), inhibition (beta = 0.096), cognitive flexibility (beta = 0.149), motor coordination (beta = 0.114) and working memory (beta = 0.156), whereas depression and anxiety symptoms were associated (p < .01) with poorer sustained attention (beta = -0.134), inhibition (beta = -0.139), cognitive flexibility (beta = 0.116) and executive function (beta = -0.139). Bivariate twin modelling showed well-being shared a small environmental correlation with motor coordination and a small genetic correlation with working memory. Trivariate twin modelling showed well-being shared a small genetic correlation with inhibition, whereas depression and anxiety symptoms shared a small environmental correlation with inhibition. The remaining variance was mostly driven by unique G and/or E variance. Overall, well-being and depression and anxiety symptoms show both independent and shared relationships with cognitive functions but this is largely attributable to unique G or E variance and small shared G/E variance between pairs of variables.

AB - Kynurenic acid (KYNA) is an endogenous substance produced on the kynurenine pathway which is primarily known for its neuroactive properties. Recently, it has been proven that KYNA is a selective ligand for G protein-coupled receptor (GPR 35), presented on immunocompetent cells such as T lymphocytes. This opens up new possibilities of its application as an immunostimulating substance in aquaculture. Thus far, no histopathological investigations in fish have been completed to evaluate influence of KYNA supplementation in feed. This study has been undertaken to determine the effect of feed supplementation with KYNA (2.5, 25, 250 mg kg-1 of feed) for 28 days on the liver, gills and kidney in healthy fish and experimentally infected with Yersinia ruckeri. In a control group were observed a fatty liver, which is natural for this fish species in the autumn and winter season. As the dose of the supplement was increased, the fat liver changed, it decreased or completely disappeared. Additionally, inflammatory changes occurred in all the analysed organs, and their intensification was dose dependent. In the fish experimentally infected, KYNA caused aggravation of the signs in the liver, kidneys and gills, and the effect was dose dependent. The results implicate that KYNA may be a stressor for fish. PMID- 27690268 TI - The role of dispersive forces determining the energetics of adsorption in Ti zeolites. AB - Ti-zeolites are interesting materials because of their key role in partial oxidation reactions, as well as under a fundamental point of view being regarded as single site catalysts. Both experimental and computational approaches have been widely applied to the characterization of their active sites, reaching a level of knowledge unmatchable by most other important catalysts. However, several questions are still open, being a proper energetic simulation of the adsorption process of simple molecules, fitting with the experimental outcomes, still missing. The present work wants to underline the role of dispersive forces in correctly determining the adsorption energies of H2 O and NH3 in Ti chabazite: first dispersive contributions have been included through an ONIOM scheme, comparing the results from semiempirical Grimme scheme and fully ab initio MP2. Being the key contribution of dispersion proved, a fully periodic, Grimme dispersions inclusive approach has been applied, coming to results close to the experimental values.

Here, we used controlled laboratory inoculations of newly settled, aposymbiotic corals (Orbicella faveolata) with two cultured species of algal symbiont (Symbiodinium microadriaticum and S. minutum) to examine the role of symbiont identity on growth, survivorship, and thermal tolerance of the coral holobiont. We evaluated these data in the context of Symbiodinium photophysiology for 9 months post settlement and also during a 5-d period of elevated temperatures Our data show that recruits that were inoculated with S. minutum grew significantly slower than those inoculated with S. microadriaticum (occasionally co-occurring with S. minutum), but that there was no difference in survivorship of O. faveolata polyps infected with Symbiodinium. However, photophysiological metrics (?Fv/F'm, the efficiency with which available light is used to drive photosynthesis and alpha, the maximum light utilization coefficient) were higher in those slower growing recruits containing S. minutum. These findings suggest that light use (i.e., photophysiology) and carbon acquisition by the coral host (i.e., host growth) are decoupled, but did not distinguish the source of this difference. Neither Symbiodinium treatment demonstrated a significant negative effect of a 5-d exposure to temperatures as high as 32 degrees C under low light conditions similar to those measured at settlement habitats. PMID- 27690270 TI - Hepatotoxicity prediction by systems biology modeling of disturbed metabolic pathways using gene expression data. AB - The present study applies a systems biology approach for the in silico predictive modeling of drug toxicity on the basis of high-quality preclinical drug toxicity data with the aim of increasing the mechanistic understanding of toxic effects of compounds at different levels (pathway, cell, tissue, organ). The model development was carried out using 77 compounds for which gene expression data for treated primary human hepatocytes is available in the LINCS database and for which rodent in vivo hepatotoxicity information is available in the eTOX database. The data from LINCS were used to determine the type and number of pathways disturbed by each compound and to estimate the extent of disturbance (network perturbation elasticity), and were used to analyze the correspondence with the in vivo information from eTOX. Predictive models were developed through this integrative analysis, and their specificity and sensitivity were assessed. The quality of the predictions was determined on the basis of the area under the curve (AUC) of plots of true positive vs. false positive rates (ROC curves). The ROC AUC reached values of up to 0.9 (out of 1.0) for some hepatotoxicity endpoints. Moreover, the most frequently disturbed metabolic pathways were determined across the studied toxicants. They included, e.g., mitochondrial beta oxidation of fatty acids and amino acid metabolism. The process was exemplified by successful predictions on various statins. In conclusion, an entirely new approach linking gene expression alterations to the prediction of complex organ toxicity was developed and evaluated. PMID- 27690265 TI - DNA methylation-based measures of biological age: meta-analysis predicting time to death. AB - Estimates of biological age based on DNA methylation patterns, often referred to as "epigenetic age", "DNAm age", have been shown to be robust biomarkers of age in humans. We previously demonstrated that independent of chronological age, epigenetic age assessed in blood predicted all-cause mortality in four human cohorts. Here, we expanded our original observation to 13 different cohorts for a total sample size of 13,089 individuals, including three racial/ethnic groups. In addition, we examined whether incorporating information on blood cell composition into the epigenetic age metrics improves their predictive power for mortality. All considered measures of epigenetic age acceleration were predictive of mortality (p<=8.2x10-9), independent of chronological age, even after adjusting for additional risk factors (p<5.4x10-4), and within the racial/ethnic groups that we examined (non-Hispanic whites, Hispanics, African Americans). Epigenetic age estimates that incorporated information on blood cell composition led to the smallest p-values for time to death (p=7.5x10-43). Overall, this study a) strengthens the evidence that epigenetic age predicts all-cause mortality above and beyond chronological age and traditional risk factors, and b) demonstrates that epigenetic age estimates that incorporate information on blood cell counts lead to highly significant associations with all-cause mortality.

PMID- 27690272 TI - Considerations for successful cancer immunotherapy in aged hosts. AB - Immunotherapy is now experiencing unprecedented successes in treating various cancers based on new understandings of cancer immunopathogenesis. Nonetheless, although ageing is the biggest risk factor for cancer, the majority of cancer immunotherapy preclinical studies are conducted in young hosts. This review will explore age-related changes in immunity as they relate to cancer immune surveillance, immunopathogenesis and responses to immunotherapy. Although it is recognized that declining T cell function with age poses a great challenge to developing effective age-related cancer immunotherapies, examples of successful approaches to overcome this hurdle have been developed. Further, it is now recognized that immune functions do not simply decline with age, but rather change in ways than can be detrimental. For example, with age, specific immune cell populations with detrimental functions can become predominant (such as cells producing proinflammatory cytokines), suppressive cells can become more numerous or more suppressive (such as myeloid-derived suppressor cells), drugs can affect aged immune cells distinctly and the aged microenvironment is becoming recognized as a significant barrier to address. Key developments in these and other areas will be surveyed as they relate to cancer immunotherapy in aged hosts, and areas in need of more study will be assessed with some speculations for the future. We propose the term 'age-related immune dysfunction' (ARID) as best representative of age-associated changes in immunity. PMID- 27690274 TI - Activation of adenylate cyclase-cyclic AMP-protein kinase A signaling by corticotropin-releasing factor within the dorsolateral bed nucleus of the stria terminalis is involved in pain-induced aversion. AB - Pain is a complex experience involving sensory and affective components. Although the neuronal mechanisms underlying the sensory component of pain have been extensively studied, those underlying its affective component have yet to be elucidated. Recently, we reported that corticotrophin-releasing factor (CRF) induced depolarization in type II neurons within the dorsolateral bed nucleus of the stria terminalis (dlBNST) is critical for pain-induced aversive responses in rats. However, the intracellular signaling underlying the excitatory effects of CRF and the contribution of such signaling to the induction of pain-induced aversion remain unclear. In the present study, we addressed these issues by conducting whole-cell patch-clamp recordings in rat brain slices and by undertaking behavioral pharmacological analyses. Intracellular perfusion of protein kinase A (PKA) inhibitor Rp-cyclic adenosine monophosphorothioate (Rp cAMPS) or KT5720 suppressed the excitatory effects of CRF in type II dlBNST neurons, and bath application of Rp-cAMPS also suppressed it. In addition, bath application of forskolin, an adenylate cyclase (AC) activator, mimicked the effects of CRF, and pretreatment with forskolin diminished the excitatory effects of CRF. Furthermore, a conditioned place aversion (CPA) test showed that co administration of Rp-cAMPS with CRF into the dlBNST suppressed CRF-induced CPA. Intra-dlBNST injection of Rp-cAMPS also suppressed pain-induced CPA. These results suggest that CRF increases excitability of type II dlBNST neurons through activation of the AC-cAMP-PKA pathway, thereby causing pain-induced aversive responses. The present findings shed light on the neuronal mechanisms underlying the negative affective component of pain and may provide therapeutic targets for treating intractable pain accompanied by psychological factors. PMID- 27690275 TI - Acidification and warming affect prominent bacteria in two seasonal phytoplankton bloom mesocosms. AB - In contrast to clear stimulatory effects of rising temperature, recent studies of the effects of CO2 on planktonic bacteria have reported conflicting results. To better understand the potential impact of predicted climate scenarios on the development and performance of bacterial communities, we performed bifactorial mesocosm experiments (pCO2 and temperature) with Baltic Sea water, during a diatom dominated bloom in autumn and a mixed phytoplankton bloom in summer. The development of bacterial community composition (BCC) followed well-known algal bloom dynamics. A principal coordinate analysis (PCoA) of bacterial OTUs (operational taxonomic units) revealed that phytoplankton succession and temperature were the major variables structuring the bacterial community whereas the impact of pCO2 was weak. Prokaryotic abundance and carbon production, and organic matter concentration and composition were partly affected by temperature but not by increased pCO2 . However, pCO2 did have significant and potentially direct effects on the relative abundance of several dominant OTUs; in some cases, these effects were accompanied by an antagonistic impact of temperature. Our results suggest the necessity of high-resolution BCC analyses and statistical analyses at the OTU level to detect the strong impact of CO2 on specific bacterial groups, which in turn might also influence specific organic matter degradation processes. PMID- 27690276 TI - Characterization and biocompatibility evaluation of bacterial cellulose-based wound dressing hydrogel: effect of electron beam irradiation doses and concentration of acrylic acid. AB - The use of bacterial cellulose (BC)-based hydrogel has been gaining attention owing to its biocompatibility and biodegradability. This study was designed to investigate the effect of radiation doses and acrylic acid (AA) composition on in vitro and in vivo biocompatibility of BC/AA as wound dressing materials. Physical properties of the hydrogel, that is, thickness, adhesiveness, rate of water vapor transmission, and swelling were measured. Moreover, the effect of these parameters on skin irritation and sensitization, blood compatibility, and cytotoxicity was studied. Increased AA content and irradiation doses increased the thickness, crosslinking density, and improved the mechanical properties of the hydrogel, but reduced its adhesiveness. The swelling capacity of the hydrogel increased significantly with a decrease in the AA composition in simulated wound fluid. The water vapor permeability of polymeric hydrogels was in the range of 2035-2666 [g/(m-2 day-1 )]. Dermal irritation and sensitization test demonstrated that the hydrogel was nonirritant and nonallergic. The BC/AA hydrogel was found to be nontoxic to primary human dermal fibroblast skin cells with viability >88% and was found to be biocompatible with blood with a low hemolytic index (0.80-1.30%). Collectively, these results indicate that these hydrogels have the potential to be used as wound dressings. (c) 2016 Wiley Periodicals, Inc.

PMID- 27690279 TI - Ectopic models for endochondral ossification: comparing pellet and alginate bead culture methods. AB - Key aspects of native endochondral bone development and fracture healing can be mimicked in mesenchymal stem cells (MSCs) through standard in vitro chondrogenic induction. Exploiting this phenomenon has recently emerged as an attractive technique to engineer bone tissue, however, relatively little is known about the best conditions for doing so. The objective of the present study was to compare the bone-forming capacity and angiogenic induction of hypertrophic cell constructs containing human adipose-derived stem cells (hASCs) primed for chondrogenesis in two different culture systems: high-density pellets and alginate bead hydrogels. The hASC constructs were subjected to 4 weeks of identical chondrogenic induction in vitro, encapsulated in an agarose carrier, and then implanted subcutaneously in immune-compromised mice for 8 weeks to evaluate their endochondral potential. At the time of implantation, both pellets and beads expressed aggrecan and type II collagen, as well as alkaline phosphatase (ALP) and type X collagen. Interestingly, ASCs in pellets formed a matrix containing higher glycosaminoglycan and collagen contents than that in beads, and ALP activity per cell was higher in pellets. However, after 8 weeks in vivo, pellets and beads induced an equivalent volume of mineralized tissue and a comparable level of vascularization. Although osteocalcin and osteopontin positive osteogenic tissue and new vascular growth was found within both types of constructs, all appeared to be better distributed throughout the hydrogel beads. The results of this ectopic model indicate that hydrogel culture may be an attractive alternative to cell pellets for bone tissue engineering via the endochondral pathway.

AB - Oro-facial pain research has during the last decades provided important novel insights into the basic underlying mechanisms, the need for standardised diagnostic procedures and classification systems, and multiple treatment options for successful rehabilitation of the patient in pain. Notwithstanding the significant progress in our knowledge spanning from molecules to chair, there may also be limitations in our ability to integrate and interpret the tremendous amount of new data and information, in particular in terms of the clinical implications and overriding conceptual models for oro-facial pain. The aim of the present narrative review is to briefly summarise some of the current thoughts on oro-facial pain mechanisms and recent attempts to identify biomarkers and risk factors leading to the proposal of a new risk assessment diagram for oro-facial pain (RADOP) and a provocative new concept based on stochastic variation between multiple risk factors. Finally, the implications for novel management strategies will briefly be discussed. PMID- 27690280 TI - Van der Waals Force Isolation of Monolayer MoS2.

PMID- 27690282 TI - Validation of a Chromosomal Microarray for Prenatal Diagnosis Using a Prospective Cohort of Pregnancies with Increased Risk for Chromosome Abnormalities. AB - AIM: Validation of a chromosomal microarray for improved prenatal diagnosis for chromosomal abnormalities among high-risk pregnancies. METHODS: A cohort of 213 pregnancies was investigated by chromosomal microarray and the results were compared with quantitative fluorescent polymerase chain reaction (QF-PCR), karyotype, and 850K single-nucleotide polymorphism microarray results. The detection limit of mosaicism was determined by assaying different trisomy mosaic constructs down to ~12%. Imprecision estimates from replicates of mean log2 ratio values for a 200 kb deletion and 400 kb duplication were determined by evaluating the coefficient of variation (CV%). RESULTS: Excluding pregnancies with aneuploidy, the chromosomal microarray detected 19/213 (8.9%) pregnancies with copy number abnormalities. These were classified as pathogenic in 11/213 (5.2%) cases, as variants of uncertain significance in 4/213 (1.9%) cases, and as likely benign in 4/213 (1.9%) cases. In 15/213 (7.0%) pregnancies, these abnormalities were not detectable by karyotype. Importantly, 8/11 (72.7%) of the pathogenic abnormalities detected by chromosomal microarray were only detectable by this modality. There were no false-positive results and only eight false-negative results. The chromosomal microarray showed excellent sensitivity (96.2%) and specificity (100.0%). The lower detection limit for mosaicism was ~12%. Imprecision for the 0.2 Mb deletion (11.6 CV%) and 0.4 Mb duplication (5.9 CV%) was very low. CONCLUSION: This chromosomal microarray showed excellent diagnostic performance with improved detection rates compared to karyotyping for prenatal diagnosis of clinically relevant fetal chromosomal abnormalities. PMID- 27690284 TI - Recovery of functionally-active protein from inclusion bodies using a thermal cycling method. AB - Heterologous overexpression of genes in Escherichia coli has made it possible to obtain high titers of recombinant proteins. However, this can result in the formation of aggregated protein particles known as 'inclusion bodies'. Protein sequestered as inclusion body is inactive and needs to be converted back to its functional form by refolding using appropriate techniques. In the current study inclusion bodies of the enzyme aminoglycoside nucleotidyl transferase (or ANT(2") Ia) were first solubilized in urea and subsequently subjected to thermal cycling under controlled conditions as part of the refolding strategy. Thermal cycling led to disaggregation of the individual protein chains and simultaneously refolding the released protein molecules to their native state. The optimum condition was identified as 10-80 degrees C thermal cycling at 3 degrees C s-1 for 2 h. Enzyme activity measurements showed that thermal cycling under optimized conditions resulted in 257% activity recovery when compared with nonrefolded protein.

AB - BACKGROUND: We undertook to study possible determinants of female sexual dysfunction (FSD) in a large cohort of female medical students from German speaking countries. METHODS: We conducted an online questionnaire-based anonymous survey in a cohort of >2600 female medical students enrolled at German-speaking universities. The questionnaire comprised the Female Sexual Function Index (FSFI) plus additional questions regarding contraception, sexual activity, age, height, weight, lifestyle, activity at work, sexuality and emotional interaction with a steady partner, pregnancy history and plans, health problems, and self acceptance. Data analysis employed descriptive statistics, univariate and multivariate analyses, and standard nonparametric tests. RESULTS: Of the 2612 respondents aged <=30 years included in the analysis (mean age [standard deviation], 23.5 [2.5] years), 38.7% of the overall cohort and 33.5% of the sexually active subcohort (91.8% of all students) were at risk for FSD (FSFI score <26.55). Multivariate analysis revealed the following significant factors to be associated with the FSFI: alcohol consumption, level of fitness, use of contraception, steady relationship, and self-acceptance (overall cohort and sexually active subcohort); smoking (overall cohort only); and body mass index and activity at work (sexually active subcohort only). CONCLUSIONS: Almost 40% of German-speaking female medical students are at risk for FSD. Contraception, smoking, alcohol, steady relationship, physical fitness, and self-acceptance are significantly associated with the FSFI total score. Being in a steady relationship, better physical fitness, higher activity at work, and subjectively positive self-acceptance, in particular, are associated with higher FSFI total scores, that is, with less risk for sexual dysfunction. PMID- 27690285 TI - Individual joint contribution to body weight support in the affected lower limb during walking in post-stroke hemiplegia. AB - OBJECTIVE: Patients with post-stroke hemiplegia have difficulty with body weight support during walking. However, it is unclear which intra-limb strategy for body weight support tends to predominate, and how the intra-limb strategy is related to gait function. Support moment and individual joint contribution to support moment are the parameters that reflect intra-limb strategy for body weight supporting. The aim of this study was to test whether support moment and individual joint contributions differed between post-stroke subjects with different gait function. METHOD: Laboratory gait analysis was performed for 14 non-hemiplegic elderly (NE) and 12 post-stroke hemiplegic elderly walking without cane (HNC) and 11 walking with a cane (HWC). Data were obtained for the vertical ground reaction force (vGRF) curve, 1st peak and 2nd peak of vGRF and corresponding temporal occurrences. Support moment (Ms) was numerical sum of hip extension, knee extension, and ankle plantar flexion moment. Individual joint contribution was calculated as the ratio of each joint moment to support moment. At temporal occurrences of vGRF peaks, Ms and individual joint contribution to Ms were calculated. Ms and individual joint contribution to Ms were compared among NE, HNC and HWC groups. Each subject's characteristics of individual joint contribution to Ms were explored. RESULTS: At the 1st peak of vGRF, support moments were similar among the three groups. However, the hip contributions were significantly greater in the NE group than in the other two groups, the ankle contributions were significantly greater in the HNC group than in the NE group. Notably, some of the subjects with post-stroke hemiplegia showed atypical characteristics that did not correspond to the group characteristics. CONCLUSION: Observing support moment and individual joint contribution is helpful to ascertain not only group characteristics, but also individual characteristics of intra-limb strategy for weight support in patients with post-stroke hemiplegia. PMID- 27690286 TI - Effects of physical exercise on musculoskeletal disorders, stress and quality of life in workers. AB - BACKGROUND: The effect of physical exercise in the workplace (PEW) on health promotion of workers is contradictory. OBJECTIVE: To evaluate the effects of the PEW in musculoskeletal disorders (MSDs), perception of stress and quality of life in workers. METHODS: The participants were divided into two groups: control group (n = 46) including non-participant workers of the PEW program, and PEW group (n = 50) including workers who regularly participate in the exercise program. All workers answered the Nordic general questionnaire, the perceived stress scale and the quality-of-life questionnaire. RESULTS: The PEW group reported a lower prevalence of MSDs for the trunk in the last 7 days and 12 months (p = 0.021 and p = 0.001, respectively), and for the upper limbs in the last 12 months (p = 0.001) compared with the control group . The results for the perception of stress and quality of life showed no significant differences between the groups. CONCLUSION: PEW is a potential method to reduce MSDs in workers, but it was not efficient in reducing stress levels or improving the quality of life of the workers. PMID- 27690287 TI - Feasibility of using low-cost portable particle monitors for measurement of fine and coarse particulate matter in urban ambient air. AB - : Exposure to ambient particulate matter (PM) is known as a significant risk factor for mortality and morbidity due to cardiorespiratory causes. Owing to increased interest in assessing personal and community exposures to PM, we evaluated the feasibility of employing a low-cost portable direct-reading instrument for measurement of ambient air PM exposure. A Dylos DC 1700 PM sensor was collocated with a Grimm 11-R in an urban residential area of Houston Texas. The 1-min averages of particle number concentrations for sizes between 0.5 and 2.5 um (small size) and sizes larger than 2.5 um (large size) from a DC 1700 were compared with the 1-min averages of PM2.5 (aerodynamic size less than 2.5 um) and coarse PM (aerodynamic size between 2.5 and 10 um) concentrations from a Grimm 11 R. We used a linear regression equation to convert DC 1700 number concentrations to mass concentrations, utilizing measurements from the Grimm 11-R. The estimated average DC 1700 PM2.5 concentration (13.2 +/- 13.7 ug/m3) was similar to the average measured Grimm 11-R PM2.5 concentration (11.3 +/- 15.1 ug/m3). The overall correlation (r2) for PM2.5 between the DC 1700 and Grimm 11-R was 0.778. The estimated average coarse PM concentration from the DC 1700 (5.6 +/- 12.1 ug/m3) was also similar to that measured with the Grimm 11-R (4.8 +/- 16.5 ug/m3) with an r2 of 0.481. The effects of relative humidity and particle size on the association between the DC 1700 and the Grimm 11-R results were also examined. The calculated PM mass concentrations from the DC 1700 were close to those measured with the Grimm 11-R when relative humidity was less than 60% for both PM2.5 and coarse PM. Particle size distribution was more important for the association of coarse PM between the DC 1700 and Grimm 11-R than it was for PM2.5. IMPLICATIONS: The performance of a low-cost particulate matter (PM) sensor was evaluated in an urban residential area. Both PM2.5 and coarse PM (PM10-2.5) mass concentrations were estimated using a DC1700 PM sensor. The calculated PM mass concentrations from the number concentrations of DC 1700 were close to those measured with the Grimm 11-R when relative humidity was less than 60% for both PM2.5 and coarse PM. Particle size distribution was more important for the association of coarse PM between the DC 1700 and Grimm 11-R than it was for PM2.5. PMID- 27690288 TI - The distribution of melanopsin (OPN4) protein in the human brain. AB - Until now, melanopsin (OPN4) - a specialized photopigment being responsive especially to blue light wavelengths - has not been found in the human brain at protein level outside the retina. More specifically, OPN4 has only been found in about 2% of retinal ganglion cells (i.e. in intrinsically photosensitive retinal ganglion cells), and in a subtype of retinal cone-cells. Given that Allen Institute for Brain Science has described a wide distribution of OPN4 mRNA in two human brains, we aimed to investigate whether OPN4 is present in the human brain also at protein level. Western blotting and immunohistochemistry, as well as immunoelectron microscopy, were used to analyse the existence and distribution of OPN4 protein in 18 investigated areas of the human brain in samples obtained in forensic autopsies from 10 male subjects (54 +/- 3.5 years). OPN4 protein expression was found in all subjects, and, furthermore, in 5 out of 10 subjects in all investigated brain areas localized in membranous compartments and cytoplasmic vesicles of neurons. To our opinion, the wide distribution of OPN4 in central areas of the human brain evokes a question whether ambient light has important straight targets in the human brain outside the retinohypothalamic tract (RHT). Further studies are, however, needed to investigate the putative physiological phototransductive actions of inborn OPN4 protein outside the RHT in the human brain. PMID- 27690289 TI - Emergency Medical Dispatchers Can Obtain Accurate Pediatric Weights from 9-1-1 Callers. AB - BACKGROUND: Prehospital pediatric drug dosing errors affect 56,000 U.S. children annually. An accurate weight is the first step in accurate dosing. To date, the accuracy of Emergency Medical Dispatcher (EMD) obtained weights has not been evaluated. We hypothesized that EMD could obtain accurate pediatric weights. METHODS: We used a convenience sample of patients 12 years and younger that were transported by EMS to one children's hospital. EMD obtained patient weight (DW) from the 9-1-1 caller. Paramedics reported their estimate of the patient's weight on arrival to the hospital (PW). The DW and PW were compared to the hospital scale weight (HW) for accuracy. RESULTS: A total of 197 patients were included. Parent/guardians were the most frequent 9-1-1 callers (74%). The most frequent method utilized by paramedics to obtain patient weight was to ask a family member. For 0-2 year olds, the mean differences between HW and DW/PW were 0.239kg (SD 3.117)/ -0.374 (SD 2.528). For 3-7 year olds, the mean differences between HW and DW/PW were 0.041kg (SD 4.684)/1.007 (SD 2.466). For 8-11 year olds the mean difference between HW and DW/PW was 2.768 kg (SD 10.926)/ 1.919 (SD 6.909). CONCLUSION: EMD were able to obtain pediatric patient weights with relative accuracy for patients 0-7 year old. Using this EMD-obtained weight to carry out a drug dose calculation would be unlikely to result in a clinically significant dose error in the vast majority of cases. Communicating an EMD-obtained weight to EMS crews en route to a pediatric patient offers additional preparation time for drug calculations, which could improve accuracy. PMID- 27690290 TI - Non-Fourier based thermal-mechanical tissue damage prediction for thermal ablation. AB - Prediction of tissue damage under thermal loads plays important role for thermal ablation planning. A new methodology is presented in this paper by combing non Fourier bio-heat transfer, constitutive elastic mechanics as well as non-rigid motion of dynamics to predict and analyze thermal distribution, thermal-induced mechanical deformation and thermal-mechanical damage of soft tissues under thermal loads. Simulations and comparison analysis demonstrate that the proposed methodology based on the non-Fourier bio-heat transfer can account for the thermal-induced mechanical behaviors of soft tissues and predict tissue thermal damage more accurately than classical Fourier bio-heat transfer based model.

AB - PURPOSE: We aimed to determine the health costs and social outcomes in terms of education, employment and income level after insertion of a vagus nerve stimulator (VNS) in patients with epilepsy. METHODS: This is a case-control study using Danish health care and socioeconomic register data. The analysis of the effect involved a comparison of the health care costs, occupation and income status of VNS-treated epilepsy patients with those of a control group of epilepsy patients who had a VNS implanted during the 12 months before the index date (pre period) and during the two years after the index date (post-period). RESULTS: 101 patients who had undergone VNS implantation and 390 control patients were included. VNS implantation was associated with fewer inpatient admissions and emergency room visits and less frequent use of prescription medication compared with epilepsy patients without VNS implantation. VNS implantation was not associated with changes in occupational status (including employment and income). In fact, the number of people on disability pension increased during the period. CONCLUSIONS: VNS implantation in people with epilepsy is associated with reduced health care use, but not with occupational or social status. PMID- 27690294 TI - Phase III randomized trial of autologous cytokine-induced killer cell immunotherapy for newly diagnosed glioblastoma in Korea. AB - PURPOSE: Adoptive cell immunotherapy involves an ex vivo expansion of autologous cytokine-induced killer (CIK) cells before their reinfusion into the host. We evaluated the efficacy and safety of CIK cell immunotherapy with radiotherapy temozolomide (TMZ) for the treatment of newly diagnosed glioblastomas. EXPERIMENTAL DESIGN: In this multi-center, open-label, phase 3 study, we randomly assigned patients with newly diagnosed glioblastoma to receive CIK cell immunotherapy combined with standard TMZ chemoradiotherapy (CIK immunotherapy group) or standard TMZ chemoradiotherapy alone (control group). The efficacy endpoints were analyzed in the intention-to-treat set and in the per protocol set. RESULTS: Between December 2008 and October 2012, a total of 180 patients were randomly assigned to the CIK immunotherapy (n = 91) or control group (n = 89). In the intention-to-treat analysis set, median PFS was 8.1 months (95% confidence interval (CI), 5.8 to 8.5 months) in the CIK immunotherapy group, as compared to 5.4 months (95% CI, 3.3 to 7.9 months) in the control group (one sided log-rank, p = 0.0401). Overall survival did not differ significantly between two groups. Grade 3 or higher adverse events, health-related quality of life and performance status between two groups did not show a significant difference. CONCLUSIONS: The addition of CIK cells immunotherapy to standard chemoradiotherapy with TMZ improved PFS. However, the CIK immunotherapy group did not show evidence of a beneficial effect on overall survival. PMID- 27690297 TI - Improving needle biopsy accuracy in small renal mass using tumor-specific DNA methylation markers. AB - PURPOSE: The clinical management of small renal masses (SRMs) is challenging since the current methods for distinguishing between benign masses and malignant renal cell carcinomas (RCCs) are frequently inaccurate or inconclusive. In addition, renal cancer subtypes also have different treatments and outcomes. High false negative rates increase the risk of cancer progression and indeterminate diagnoses result in unnecessary and potentially morbid surgical procedures. EXPERIMENTAL DESIGN: We built a predictive classification model for kidney tumors using 697 DNA methylation profiles from six different subgroups: clear cell, papillary and chromophobe RCC, benign angiomylolipomas, oncocytomas, and normal kidney tissues. Furthermore, the DNA methylation-dependent classifier has been validated in 272 ex vivo needle biopsy samples from 100 renal masses (71% SRMs). RESULTS: In general, the results were highly reproducible (89%, n=70) in predicting identical malignant subtypes from biopsies. Overall, 98% of adjacent normals (n=102) were correctly classified as normal, while 92% of tumors (n=71) were correctly classified malignant and 86% of benign (n=29) were correctly classified benign by this classification model. CONCLUSIONS: Overall, this study provides molecular-based support for using routine needle biopsies to determine tumor classification of SRMs and support the clinical decision-making.

Macrophages, natural killer (NK) cells, natural killer T (NKT) cells, dendritic cells (DC), eosinophils, gamma delta T (gammadeltaT) cells, and conventional T cells, as well as other subsets of the immune cells residing in the liver control liver regeneration, either through direct interactions with hepatocytes or indirectly by releasing inflammatory cytokines. Here, we review recent progress regarding the immune cells in the liver and their functions during liver regeneration. PMID- 27690298 TI - Glucuronidation and UGT isozymes in bladder: new targets for the treatment of uroepithelial carcinomas? AB - Bladder cancer has been linked to numerous toxins which can be concentrated in the bladder after being absorbed into the blood and filtered by the kidneys. Excessive carcinogenic load to the bladder urothelium may result in the development of cancer. However, enzymes within the bladder can metabolize carcinogens into substrates that are safer. Importantly, these proteins, namely the UGT's (uridine 5'-diphospho-glucuronosyltransferases), have been shown to possibly prevent bladder cancer. Also, studies have shown that the UGT1 expression is decreased in uroepithelial carcinomas, which may allow for the accumulation of carcinogens in the bladder. In this review, we discuss the UGT system and its' protective role against bladder cancer, UGT genetic mutations that modulate risk from chemicals and environmental toxins, as well as targeting of the UGT enzymes by nuclear receptors. PMID- 27690295 TI - Factors and pathways involved in capacitation: how are they regulated? AB - In mammals, fertilization occurs via a comprehensive progression of events. Freshly ejaculated sperm have yet to acquire progressive motility or fertilization ability. They must first undergo a series of biochemical and physiological changes, collectively known as capacitation. Capacitation is a significant prerequisite to fertilization. During the process of capacitation, changes in membrane properties, intracellular ion concentration and the activities of enzymes, together with other protein modifications, induce multiple signaling events and pathways in defined media in vitro or in the female reproductive tract in vivo. These, in turn, stimulate the acrosome reaction and prepare spermatozoa for penetration of the egg zona pellucida prior to fertilization. In the present review, we conclude all mainstream factors and pathways regulate capacitation and highlight their crosstalk. We also summarize the relationship between capacitation and assisted reproductive technology or human disease. In the end, we sum up the open questions and future avenues in this field. PMID- 27690300 TI - Correlation analysis between 2D and quasi-3D gamma evaluations for both intensity modulated radiation therapy and volumetric modulated arc therapy. AB - The aim of this work was to investigate correlations between 2D and quasi-3D gamma passing rates. A total of 20 patients (10 prostate cases and 10 head and neck cases, H&N) were retrospectively selected. For each patient, both intensity modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) plans were generated. For each plan, 2D gamma evaluation with radiochromic films and quasi-3D gamma evaluation with fluence measurements were performed with both 2%/2 mm and 3%/3 mm criteria. Gamma passing rates were grouped together according to delivery techniques and treatment sites. Statistical analyses were performed to examine the correlation between 2D and quasi-3D gamma evaluations. Statistically significant difference was observed between delivery techniques only in the quasi-3D gamma passing rates with 2%/2 mm. Statistically significant differences were observed between treatment sites in the 2D gamma passing rates (differences of less than 8%). No statistically significant correlations were observed between 2D and quasi-3D gamma passing rates except the VMAT group and the group including both IMRT and VMAT with 3%/3 mm (r = 0.564 with p = 0.012 for theVMAT group and r = 0.372 with p = 0.020 for the group including both IMRT and VMAT), however, those were not strong. No strong correlations were observed between 2D and quasi-3D gamma evaluations. PMID- 27690301 TI - MiR-128 reverses the gefitinib resistance of the lung cancer stem cells by inhibiting the c-met/PI3K/AKT pathway. AB - Gefitinib is a first line anti-tumor drug used for the treatment of patients with non-small cell lung cancer (NSCLC) harboring EGFR mutations. However, the drug resistance to gefitinib limits its clinical application. Here, we observed the CSCs of PC9 are obviously resistant to gefitinib compared with the non-CSCs. Furthermore, we found the gefitinib failed to suppress the PI3K/AKT pathway in the PC9-CSCs. Mechanically, we showed significant down-regulation of miR-128 in the PC9-CSCs compared with the non-CSCs. Overexpression of miR-128 significantly increased the sensitivity of PC9-CSCs to gefitinib-induced apoptosis. In addition, the gene of c-met was proved to be directly inhibited by miR-128. Enforced expression of c-met could "rescue" the miR-128 promoted apoptosis and cleavage of caspases in PC9-CSCs treated with gefitinib. Thus, these results indicate that the miR-128/c-met pathway enhances the gefitinib sensitivity of the lung cancer stem cells by suppressing the PI3K/AKT pathway. PMID- 27690302 TI - Identification of novel prognostic indicators for triple-negative breast cancer patients through integrative analysis of cancer genomics data and protein interactome data. AB - Triple negative breast cancers (TNBCs) are highly heterogeneous and aggressive without targeted treatment. Here, we aim to systematically dissect TNBCs from a prognosis point of view by building a subnetwork atlas for TNBC prognosis through integrating multi-dimensional cancer genomics data from The Cancer Genome Atlas (TCGA) project and the interactome data from three different interaction networks. The subnetworks are represented as the protein-protein interaction modules perturbed by multiple genetic and epigenetic interacting mechanisms contributing to patient survival. Predictive power of these subnetwork-derived prognostic models is evaluated using Monte Carlo cross-validation and the concordance index (C-index). We uncover subnetwork biomarkers of low oncogenic GTPase activity, low ubiquitin/proteasome degradation, effective protection from oxidative damage, and tightly immune response are linked to better prognosis. Such a systematic approach to integrate massive amount of cancer genomics data into clinical practice for TNBC prognosis can effectively dissect the molecular mechanisms underlying TNBC patient outcomes and provide potential opportunities to optimize treatment and develop therapeutics. PMID- 27690299 TI - On the origin of myeloid-derived suppressor cells. AB - Myeloid-derived suppressor cells (MDSCs) have a strong immunosuppressive character that allows them to regulate immune responses and hinder overt inflammatory responses. In cancer, this leads to tumor immune evasion and disease progression. MDSCs come in at least two forms: monocytic (Mo-MDSCs) and granulocytic (G-MDSCs). The classical definition of MDSCs as immature myeloid cells blocked from differentiating has been challenged by recent studies suggesting that Mo-MDSCs and G-MDSCs may represent monocytes and granulocytes that have acquired immunosuppressive properties. The molecular mechanism behind their generation and their true origins are now widely debated. In this review we discuss the different proposed mechanisms of the generation of both types of MDSCs, with a special focus on human MDSCs in cancer. PMID- 27690303 TI - Intratumoral radiofrequency hyperthermia-enhanced direct chemotherapy of pancreatic cancer. AB - PURPOSE: To investigate the technical feasibility of using ultrasound-guided intratumoral radiofrequency hyperthermia (RFH) to enhance local chemotherapy of rat orthotopic pancreatic cancers. MATERIALS AND METHODS: Orthotopic pancreatic cancer masses were established by inoculating luciferase/mCherry labeled pancreatic cancer cells into the pancreatic tails of Lewis model rats via a laparotomy approach. Twenty-four rats with pancreatic cancer and 24 mice with subcutaneous pancreatic cancer xenografts in four study groups (n = 6/group) received various treatments: i) combination therapy of intratumoral MR imaging heating-guidewire-mediated RFH (42oC) plus local chemotherapy (gemcitabine); ii) intratumoral chemotherapy alone; iii) RFH alone; and (iv)phosphate-buffered saline (PBS). Transcutaneous ultrasound imaging was used to guide the treatment and subsequently follow changes in tumor sizes. Bioluminescence optical imaging was performed to follow photon signal changes. Sonographic and optical findings were correlated with histology at 14 days. RESULTS: Optical imaging demonstrated a significantly decreased bioluminescence signal in mice with combination therapy group, compared with the other control groups (0.51+/-0.18 VS 1.6+/-0.4 VS 3.18+/ 0.9 VS 3.5+/-0.96, p < 0.05). Ultrasound imaging showed the smallest tumor volumes of both mice and rat group with the combination therapy, compared with other control groups (0.62+/-0.16 VS 1.25+/-0.19 VS 2.28+/-0.25 VS 2.64+/-0.26, p < 0.05) and (0.75+/-0.18 VS 1.31+/-0.30 VS 1.61+/-0.28 VS 1.72+/-0.28, p < 0.05). Both imaging findings were confirmed by histologic correlation. CONCLUSION: Intratumoral RFH can augment the chemotherapeutic effect in an orthotopic pancreatic cancer model.

AB - The measurement of the dipolar interaction between two spins provides the distance between nuclei. A better structural picture emerges when the distance is combined with the orientation of the internuclear vector in the principal axis system of the chemical shift anisotropy tensor. The SEDOR experiment is used on a static sample of alanine to show that the orientation of the vector connecting the nitrogen and carboxylate carbon nuclei can be accurately determined in the CSA PAS of the 13C carboxylate spin. PMID- 27690304 TI - How exactly can computer simulation predict the kinematics and contact status after TKA? Examination in individualized models. AB - BACKGROUND: It is unknown whether a computer simulation with simple models can estimate individual in vivo knee kinematics, although some complex models have predicted the knee kinematics. The purposes of this study are first, to validate the accuracy of the computer simulation with our developed model during a squatting activity in a weight-bearing deep knee bend and then, to analyze the contact area and the contact stress of the tri-condylar implants for individual patients. METHODS: We compared the anteroposterior (AP) contact positions of medial and lateral condyles calculated by the computer simulation program with the positions measured from the fluoroscopic analysis for three implanted knees. Then the contact area and the stress including the third condyle were calculated individually using finite element (FE) analysis. FINDINGS: The motion patterns were similar in the simulation program and the fluoroscopic surveillance. Our developed model could nearly estimate the individual in vivo knee kinematics. The mean and maximum differences of the AP contact positions were 1.0mm and 2.5mm, respectively. At 120 degrees of knee flexion, the contact area at the third condyle was wider than the both condyles. The mean maximum contact stress at the third condyle was lower than the both condyles at 90 degrees and 120 degrees of knee flexion. INTERPRETATION: Individual bone models are required to estimate in vivo knee kinematics in our simple model. The tri-condylar implant seems to be safe for deep flexion activities due to the wide contact area and low contact stress. PMID- 27690306 TI - Liver steatosis and nonalcoholic steatohepatitis: from pathogenesis to therapy. AB - Non-alcoholic fatty liver disease refers to a disease spectrum that ranges from steatosis to non-alcoholic steatohepatitis, which leads to fibrosis, cirrhosis and hepatocellular carcinoma. Given the increasing prevalence of obesity worldwide, the incidence of non-alcoholic fatty liver disease has become a world health problem. Non-alcoholic fatty liver disease is considered to be the hepatic manifestation of metabolic syndrome associated with insulin resistance, central obesity, and type 2 diabetes mellitus. Allegedly, insulin resistance plays a pivotal role in its pathogenesis. Here we highlight non-alcoholic fatty liver disease epidemiology and pathophysiology, its progression towards steatohepatitis with particular emphasis in liver fibrosis and participation of advanced glycation end products. The different treatments reported are described here as well. We conducted a search in PubMed with the terms steatohepatitis, steatosis advanced glycation end products, liver fibrosis and adipocytokines. Articles were selected according to their relevance. PMID- 27690307 TI - Ossicular Bone Damage and Hearing Loss in Rheumatoid Arthritis: A Correlated Functional and High Resolution Morphometric Study in Collagen-Induced Arthritic Mice. AB - Globally, a body of comparative case-control studies suggests that rheumatoid arthritis (RA) patients are more prone to developing hearing loss (HL). However, experimental evidence that supports this hypothesis is still lacking because the human auditory organ is not readily accessible. The aim of this study was to determine the association between bone damage to the ossicles of the middle ear and HL, using a widely accepted murine model of collagen-induced arthritis (RA mice). Diarthrodial joints in the middle ear were examined with microcomputer tomography (microCT), and hearing function was assessed by auditory brainstem response (ABR). RA mice exhibited significantly decreased hearing sensitivity compared to age-matched controls. Additionally, a significant narrowing of the incudostapedial joint space and an increase in the porosity of the stapes were observed. The absolute latencies of all ABR waves were prolonged, but mean interpeak latencies were not statistically different. The observed bone defects in the middle ear that were accompanied by changes in ABR responses were consistent with conductive HL. This combination suggests that conductive impairment is at least part of the etiology of RA-induced HL in a murine model. Whether the inner ear sustains bone erosion or other pathology, and whether the cochlear nerve sustains pathology await subsequent studies. Considering the fact that certain anti-inflammatories are ototoxic in high doses, monitoring RA patients' auditory function is advisable as part of the effort to ensure their well-being. PMID- 27690308 TI - The Cac1 subunit of histone chaperone CAF-1 organizes CAF-1-H3/H4 architecture and tetramerizes histones. AB - The histone chaperone Chromatin Assembly Factor 1 (CAF-1) deposits tetrameric (H3/H4)2 histones onto newly-synthesized DNA during DNA replication. To understand the mechanism of the tri-subunit CAF-1 complex in this process, we investigated the protein-protein interactions within the CAF-1-H3/H4 architecture using biophysical and biochemical approaches. Hydrogen/deuterium exchange and chemical cross-linking coupled to mass spectrometry reveal interactions that are essential for CAF-1 function in budding yeast, and importantly indicate that the Cac1 subunit functions as a scaffold within the CAF-1-H3/H4 complex. Cac1 alone not only binds H3/H4 with high affinity, but also promotes histone tetramerization independent of the other subunits. Moreover, we identify a minimal region in the C-terminus of Cac1, including the structured winged helix domain and glutamate/aspartate-rich domain, which is sufficient to induce (H3/H4)2 tetramerization. These findings reveal a key role of Cac1 in histone tetramerization, providing a new model for CAF-1-H3/H4 architecture and function during eukaryotic replication. PMID- 27690310 TI - Transformation of diclofenac in hybrid biofilm-activated sludge processes. AB - The biotransformation of diclofenac during wastewater treatment was investigated. Attached growth biomass from a carrier-filled compartment of a hybrid-MBBR at the wastewater treatment plant (WWTP) in Bad Ragaz, Switzerland was used to test the biotransformation. Laboratory-scale incubation experiments were performed with diclofenac and carriers and high-resolution LC-QTof-MS was implemented to monitor the biotransformation. Up to 20 diclofenac transformation products (TPs) were detected. Tentative structures were proposed for 16 of the TPs after characterization by MS2 fragmentation and/or inferring the structure from the transformation pathway and the molecular formula given by the high resolution ionic mass. The remaining four TPs were unambiguously identified via analytical reference standards. The postulated reactions forming the TPs were: hydroxylation, decarboxylation, oxidation, amide formation, ring-opening and reductive dechlorination. Incubation experiments of individual TPs, those which were available as reference standards, provided a deeper look into the transformation pathways. It was found that the transformation consists of four main pathways but no pathway accounted for a clear majority of the transformation. A 10-day monitoring campaign of the full-scale plant confirmed an 88% removal of diclofenac (from approximately 1.6 MUg/L in WWTP influent) and the formation of TPs as found in the laboratory was observed. One of the TPs, N-(2,6 dichlorophenyl)-2-indolinone detected at concentrations of around 0.25 MUg/L in WWTP effluent, accounting for 16% of the influent diclofenac concentration. The biotransformation of carriers was compared to a second WWTP not utilising carriers. It was found that in contact with activated sludge, similar hydroxylation and decarboxylation reactions occurred but at much slower rates, whereas some reactions, e.g. reductive dechlorination, were not detected at all. Finally, incubation experiments were performed with attached growth biomass from a third WWTP with a similar process configuration to Bad Ragaz WWTP. A similarly effective removal of diclofenac was found with a similar presence of TPs. PMID- 27690309 TI - Identification of Position-Specific Correlations between DNA-Binding Domains and Their Binding Sites. Application to the MerR Family of Transcription Factors. AB - The large and increasing volume of genomic data analyzed by comparative methods provides information about transcription factors and their binding sites that, in turn, enables statistical analysis of correlations between factors and sites, uncovering mechanisms and evolution of specific protein-DNA recognition. Here we present an online tool, Prot-DNA-Korr, designed to identify and analyze crucial protein-DNA pairs of positions in a family of transcription factors. Correlations are identified by analysis of mutual information between columns of protein and DNA alignments. The algorithm reduces the effects of common phylogenetic history and of abundance of closely related proteins and binding sites. We apply it to five closely related subfamilies of the MerR family of bacterial transcription factors that regulate heavy metal resistance systems. We validate the approach using known 3D structures of MerR-family proteins in complexes with their cognate DNA binding sites and demonstrate that a significant fraction of correlated positions indeed form specific side-chain-to-base contacts. The joint distribution of amino acids and nucleotides hence may be used to predict changes of specificity for point mutations in transcription factors. PMID- 27690311 TI - Knowledge about Cervical Cancer and Associated Factors among 15-49 Year Old Women in Dessie Town, Northeast Ethiopia. AB - BACKGROUND: Cervical cancer is one of the leading causes of morbidity and mortality amongst female cancer worldwide, especially in developing countries, including Ethiopia. The level of women's knowledge about cervical cancer is not well documented in Ethiopia. The current study sought to assess women's knowledge about cervical cancer and associated factors. METHODS: A community based cross sectional survey was conducted with a sample of 620 women aged 15-49 years residing in Dessie town, Northeast Ethiopia. Respondents were selected using a multistage sampling technique. The women were interviewed at home by trained data collectors using a structured questionnaire on cervical cancer knowledge. Knowledge about cervical cancer was measured using an eight item instrument. The maximum possible score was 8; those scoring 5 or more were categorized as having "sufficient" knowledge. Binary and multiple logistic regressions were employed to determine factors associated with knowledge about cervical cancer. RESULTS: A total of 51% of the participants had sufficient knowledge about cervical cancer. After adjusting for covariates, having sufficient knowledge about cervical cancer was positively associated with better educational level and income. Women with primary education (Adjusted Odds Ratio (AOR): 3.4; 95% CI: 2.2-5.1) and those who had secondary and above education (AOR: 8.7; 95% CI: 5.5-13.7) were more likely to have sufficient knowledge about cervical cancer compared to those who had no formal education. Furthermore, women earning an average household monthly income above 1500 Ethiopian birr (ETB) (~75 U.S. dollars) were more likely to have sufficient knowledge (AOR: 2.3; 95% CI: 1.3-3.9) than women with an average household monthly income less than 500 ETB (~25 U.S. dollars). CONCLUSION: This study shows a suboptimal knowledge about cervical cancer regarding its risk factors, signs and symptoms, prevention and treatment among women in the study site. The level of education and economic status were found to be important determinants for knowledge about cervical cancer. Prevention programs should focus cervical cancer educational resources on women with less education and women with lower economic status groups. PMID- 27690312 TI - Sensitivity Analysis of Vagus Nerve Stimulation Parameters on Acute Cardiac Autonomic Responses: Chronotropic, Inotropic and Dromotropic Effects. AB - Although the therapeutic effects of Vagus Nerve Stimulation (VNS) have been recognized in pre-clinical and pilot clinical studies, the effect of different stimulation configurations on the cardiovascular response is still an open question, especially in the case of VNS delivered synchronously with cardiac activity. In this paper, we propose a formal mathematical methodology to analyze the acute cardiac response to different VNS configurations, jointly considering the chronotropic, dromotropic and inotropic cardiac effects. A latin hypercube sampling method was chosen to design a uniform experimental plan, composed of 75 different VNS configurations, with different values for the main parameters (current amplitude, number of delivered pulses, pulse width, interpulse period and the delay between the detected cardiac event and VNS onset). These VNS configurations were applied to 6 healthy, anesthetized sheep, while acquiring the associated cardiovascular response. Unobserved VNS configurations were estimated using a Gaussian process regression (GPR) model. In order to quantitatively analyze the effect of each parameter and their combinations on the cardiac response, the Sobol sensitivity method was applied to the obtained GPR model and inter-individual sensitivity markers were estimated using a bootstrap approach. Results highlight the dominant effect of pulse current, pulse width and number of pulses, which explain respectively 49.4%, 19.7% and 6.0% of the mean global cardiovascular variability provoked by VNS. More interestingly, results also quantify the effect of the interactions between VNS parameters. In particular, the interactions between current and pulse width provoke higher cardiac effects than the changes on the number of pulses alone (between 6 and 25% of the variability). Although the sensitivity of individual VNS parameters seems similar for chronotropic, dromotropic and inotropic responses, the interacting effects of VNS parameters provoke significantly different cardiac responses, showing the feasibility of a parameter-based functional selectivity. These results are of primary importance for the optimal, subject-specific definition of VNS parameters for a given therapy and may lead to new closed-loop methods allowing for the optimal adaptation of VNS therapy through time. PMID- 27690313 TI - Recent advancements in matrix-assisted laser desorption/ionization mass spectrometry imaging. AB - Matrix assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI) is a robust tool for spatially resolved analysis of biomolecules in situ. Recent advances in high ionization-efficiency MALDI matrices, new matrix deposition procedures, and the development of high spatial-resolution and high sensitivity MS instruments continue to drive new applications of MALDI-MSI, along with other MSI techniques, which allow us to visualize and determine the regio-specific and temporal changes in proteins, peptides, lipids, drug molecules, and metabolites within the tissues, cells and microorganisms. These provide researchers with a new route to the discovery of potential biomarkers of human disease and elucidation of the underlying biology of metabolic regulation, thus bringing our understanding of human health to a new level. PMID- 27690316 TI - Valley filtering by a line-defect in graphene: quantum interference and inversion of the filter effect. AB - Valley filters are crucial to any device exploiting the valley degree of freedom. By using an atomistic model, we analyze the mechanism leading to the valley filtering produced by a line-defect in graphene and show how it can be inverted by external means. Thanks to a mode decomposition applied to a tight-binding model we can resolve the different transport channels in k-space while keeping a simple but accurate description of the band structure, both close and further away from the Dirac point. This allows the understanding of a destructive interference effect, specifically a Fano resonance or antiresonance located on the p-side of the Dirac point leading to a reduced conductance. We show that in the neighborhood of this feature the valley filtering can be reversed by changing the occupations with a gate voltage, the mechanism is explained in terms of a valley-dependent Fano resonance splitting. Our results open the door for enhanced control of valley transport in graphene-based devices. PMID- 27690315 TI - The relationship between psoriasis and depression: A multiple mediation model. AB - This study examined the relationship between psoriasis and depression, proposing a multiple mediation model to analyse the relationship. A total of 193 patients with psoriasis aged 20-67 years completed the Beck Depression Inventory, the Stigmatization Scale, the Appearance Schemas Inventory-Revised, and the Body Emotions Scale. The Body Surface Area index was used to assess severity of psoriasis. Serial multiple mediation analysis revealed that experiences of stigmatization, maladaptive beliefs about appearance and its salience to one's self-evaluation, and negative emotional attitudes towards the body, jointly, sequentially mediated the relationship between the presence of skin lesions of psoriasis and depressive symptoms. These results highlight the importance of the associations between stigmatization and cognitive and affective aspects of body image in relation to depression in patients with psoriasis. We suggest that prevention and intervention programs for psoriasis patients that target body image enhancement would be worthy of further research. PMID- 27690314 TI - Widespread Shortening of 3' Untranslated Regions and Increased Exon Inclusion Are Evolutionarily Conserved Features of Innate Immune Responses to Infection. AB - The contribution of pre-mRNA processing mechanisms to the regulation of immune responses remains poorly studied despite emerging examples of their role as regulators of immune defenses. We sought to investigate the role of mRNA processing in the cellular responses of human macrophages to live bacterial infections. Here, we used mRNA sequencing to quantify gene expression and isoform abundances in primary macrophages from 60 individuals, before and after infection with Listeria monocytogenes and Salmonella typhimurium. In response to both bacteria we identified thousands of genes that significantly change isoform usage in response to infection, characterized by an overall increase in isoform diversity after infection. In response to both bacteria, we found global shifts towards (i) the inclusion of cassette exons and (ii) shorter 3' UTRs, with near universal shifts towards usage of more upstream polyadenylation sites. Using complementary data collected in non-human primates, we show that these features are evolutionarily conserved among primates. Following infection, we identify candidate RNA processing factors whose expression is associated with individual specific variation in isoform abundance. Finally, by profiling microRNA levels, we show that 3' UTRs with reduced abundance after infection are significantly enriched for target sites for particular miRNAs. These results suggest that the pervasive usage of shorter 3' UTRs is a mechanism for particular genes to evade repression by immune-activated miRNAs. Collectively, our results suggest that dynamic changes in RNA processing may play key roles in the regulation of innate immune responses. PMID- 27690317 TI - Restricted Gene Flow among Lineages of Thrips tabaci Supports Genetic Divergence Among Cryptic Species Groups. AB - Knowledge of the relative influence of population- versus species-level genetic variation is important to understand patterns of phenotypic variation and ecological relationships that exist among and within morphologically indistinguishable cryptic species and subspecies. In the case of cryptic species groups that are pests, such knowledge is also essential for devising effective population management strategies. The globally important crop pest Thrips tabaci is a taxonomically difficult group of putatively cryptic species. This study examines population genetic structure of T. tabaci and reproductive isolation among lineages of this species complex using microsatellite markers and mitochondrial COI sequences. Overall, genetic structure supports T. tabaci as a cryptic species complex, although limited interbreeding occurs between different clonal groups from the same lineage as well as between individuals from different lineages. These results also provide evidence that thelytoky and arrhenotoky are not fixed phenotypes among members of different T. tabaci lineages that have been generally associated with either reproductive mode. Possible biological and ecological factors contributing to these observations are discussed. PMID- 27690318 TI - Prevalence of diagnosed diabetes and quality of care among Greenlanders and non Greenlanders in Greenland. AB - AIMS: To estimate the actual prevalence of diagnosed diabetes in Greenland as at 2014, and to evaluate the quality of diabetes care among Greenlanders and non Greenlanders in Greenland, six years after a national diabetes program was initiated. METHODS: The study was designed as an observational cross-sectional study based on review of data obtained from the electronic medical record (EMR) in Greenland. All permanent residents of Greenland who as at October 2014 were registered with the diagnosis diabetes in the EMR (n=1071) were included in the study. The prevalence was calculated using the population in Greenland as at first of June 2014 as background population. Quality of diabetes care was determined using indicators proposed by the Organization for Economic Cooperation and Development. RESULTS: The prevalence among Greenlanders aged 20-79years was 2.36% (95% CI 2.19-2.52) and significantly lower than the prevalence among non Greenlanders in the same age group, which was 3.69% (95% CI 2.18-4.20). More Greenlanders than non-Greenlanders had glycosylated haemoglobin below 7.0% (53mmol/mol), blood pressure below 140/90mmHg and their blood pressure measured within the last year. No other differences in quality of diabetes care were observed between the groups. CONCLUSIONS: A higher prevalence of diagnosed diabetes was observed among non-Greenlanders compared to Greenlanders, while no major differences were observed in quality of care between the two groups. The overall prevalence of diagnosed diabetes has increased compared to earlier studies. Continued monitoring of prevalence and quality of care is recommended. PMID- 27690319 TI - Physical activity does not inevitably improve quality of life in young adults with type 1 diabetes. AB - Relationships between exercise, glucose control and diabetes dependent quality of life (DDQoL) are not straightforward. We investigated the DDQoL of 99 persons with type 1 diabetes and linked it to individual amount of weekly physical activity and HbA1c. Physically active lifestyle was not associated with better DDQoL or glucose control. PMID- 27690320 TI - Preliminary MALDI-TOF-MS analysis of seminal plasma N-glycome of infertile men. AB - Glycosylation pattern within reproductive tract is now suggested to be involved in providing female immune tolerance for allograft sperm and developing embryo, but the information whether impaired glycosylation may influence male fertility potential is still limited. We have analyzed seminal plasma N-glycome in pooled samples derived from fertile and infertile men by means of MALDI-TOF/TOF tandem mass spectrometry. Among infertile subjects, normozoospermic, oligozoospermic, asthenozoospermic and oligoasthenozoospermic samples were obtained. Eighty-six oligosaccharides were identified in all the analyzed samples. Differences in the content of unique glycans: high mannose and hybrid type, lacking terminal sialic acid and highly fucosylated were found when samples derived from infertile subjects with different semen patterns were compared to the fertile control. The content of highly branched glycans was 3-fold elevated in normozoospermic infertile men, while the expression of highly fucosylated oligosaccharides was increased in asthenozoospermic, oligozoospermic and oligoasthenozoospermic samples. Sialylation of oligosaccharides was decreased in oligozoospermic, oligoasthenozoospermic and especially asthenozoospermic samples, but increased in infertile normozoospermic subjects. Altered glycosylation observed in seminal plasma may reflect similar changes in sperm surface glycoproteins, and may disturb sperm interaction with female immune system. We suggest that at least some cases of unexplained male infertility may be associated with impaired glycosylation. PMID- 27690321 TI - The Versatile 2-Substituted Imidazoline Nucleus as a Structural Motif of Ligands Directed to the Serotonin 5-HT1A Receptor. AB - The involvement of the serotonin 5-HT1A receptor (5-HT1A -R) in the antidepressant effect of allyphenyline and its analogues indicates that ligands bearing the 2-substituted imidazoline nucleus as a structural motif interact with 5-HT1A -R. Therefore, we examined the 5-HT1A -R profile of several imidazoline molecules endowed with a common scaffold consisting of an aromatic moiety linked to the 2-position of an imidazoline nucleus by a biatomic bridge. Our aim was to discover other ligands targeting 5-HT1A -R and to identify the structural features favoring 5-HT1A -R interaction. Structure-activity relationships, supported by modeling studies, suggested that some structural cliche such as a polar function and a methyl group in the bridge, as well as proper steric hindrance in the aromatic area of the above scaffold, favored 5-HT1A -R recognition and activation. We also highlighted the potent antidepressant-like effect (mouse forced swimming test) of (S)-(+)-19 [(S)-(+)-naphtyline] at very low dose (0.01 mg kg-1 ). This effect was clearly mediated by 5-HT1A , as it was significantly reduced by pretreatment with the 5-HT1A antagonist WAY100635.

AB - PURPOSE: To investigate the performance of control scans in pseudo-continuous ASL (pCASL) and propose strategies for improving sensitivity and reliability of pCASL. METHODS: The labeling efficiencies of pCASL with conventional control scan and distal control scan were investigated at various radiofrequency (RF) duration/spacing of 0.5/1-2/4 ms, mean slice-selection gradients (GSS ) of 1 and 0 mT/m, and total labeling durations of 1.5-3 s, through Bloch equation simulations and in vivo experiments. In addition, the feasibility of three dimensional (3D) pCASL with the distal control scan and control scan with no RF preparation was demonstrated in a wide brain area, by suppressing the magnetization transfer (MT) effects with high GSS while maintaining the GSS /mean GSS ratio. RESULTS: The distal control scan provided pCASL signals approximately 40% higher and more robust to variations in the labeling conditions than those from the conventional control scan. The distal and no RF control scans with high GSS provided uniform pCASL signals in approximately 8-cm-thick imaging region with MT contributions <10% of the perfusion signals. CONCLUSIONS: pCASL perfusion signals can be enhanced (~40%) and become more stable by using the distal or no RF control scan, which can be applied in a wide area by increasing GSS while maintaining GSS /mean GSS .

AB - We describe the simple, scalable, single-step, and polar-solvent-free synthesis of high-quality colloidal CsPbX3 (X=Cl, Br, and I) perovskite nanocrystals (NCs) with tunable halide ion composition and thickness by direct ultrasonication of the corresponding precursor solutions in the presence of organic capping molecules. High angle annular dark field scanning transmission electron microscopy (HAADF-STEM) revealed the cubic crystal structure and surface termination of the NCs with atomic resolution. The NCs exhibit high photoluminescence quantum yields, narrow emission line widths, and considerable air stability. Furthermore, we investigated the quantum size effects in CsPbBr3 and CsPbI3 nanoplatelets by tuning their thickness down to only three to six monolayers. The high quality of the prepared NCs (CsPbBr3 ) was confirmed by amplified spontaneous emission with low thresholds. The versatility of this synthesis approach was demonstrated by synthesizing different perovskite NCs.

AB - PURPOSE: To evaluate a new dark-blood late gadolinium enhancement (LGE) technique called "T(Rho) And Magnetization transfer and INvErsion Recovery" (TRAMINER) for the ability to detect myocardial LGE versus standard "bright-blood" inversion recovery (SIR) imaging. MATERIALS AND METHODS: This Institutional Review Board (IRB)-approved, Health Insurance Portability and Accountability Act (HIPAA) compliant prospective study included 40 patients (62 +/- 14 years [mean +/- standard deviation (SD)], 29 males) with suspected myocardial infarction (MI) referred for the assessment of myocardial viability. The patients underwent a 1.5T cardiac magnetic resonance imaging (MRI) including postcontrast SIR and TRAMINER acquisitions. Normalized images were evaluated by two readers. Subjective (3-point Likert scale) and objective image qualities were compared using Mann-Whitney U-test and paired t-test, respectively. Interobserver agreement, LGE detection rate, and level of certainty were compared using Cohen's kappa, Wilcoxon-test, and Mann-Whitney U-test, respectively. Results are reported as mean +/- SD or mean [95% confidence interval]. RESULTS: Overall, image quality was rated similar between TRAMINER and SIR; however, TRAMINER performed better on a visual assessment of the ability to differentiate LGE from blood (Likert scale: 3.0 [3.0-3.0] vs. 2.0 [1.7-2.2], P < 0.0001). TRAMINER provided significantly higher signal intensity range (69.8 +/- 10.2 vs. 9.6 +/- 7.6, P < 0.0001) and a 4 fold higher signal intensity ratio (4.2 +/- 1.9 vs. 1.1 +/- 0.1, P < 0.0001) between LGE and blood signals. TRAMINER detected more patients (19/40 vs. 17/40) and segments (91/649 vs. 79/649) with LGE with higher level of certainty (2.9 [2.8-3.0] vs. 2.7 [2.5-2.8], P = 0.0185). Interobserver agreement was good to excellent for LGE detection. CONCLUSION: TRAMINER provides better contrast between LGE and blood and consequently may have increased ability to discriminate thin subendocardial and papillary muscle enhancement from the blood signal, which can have an indistinct appearance using SIR.

AB - Nowadays, there are a few steroid drugs or intermediates that have been obtained via the transformation of microorganisms, and many strains of transformed steroids have not been found yet. Therefore, it is very significant to screen for the strains that have the abilities to transform steroids to produce valuable products. This study has focused on the screen and identification of strains, the structural identification of converted products, and the optimization of transformation conditions, as well as the establishment of transformation systems. A soil microbiota was screened for strain involved in the biotransformation of steroids. A new isolate IS547 is capable of converting a variety of steroids (such as cholesterol, ergosterol, hydrocortisone, progesterone, pregnenolone, and 16,17-alpha-epoxypregnenolone). Based on the 18S rDNA gene sequence comparison, the isolate IS547 has been demonstrated to be very closely related to Cladosporium sp. genus. Present paper is the first report regarding the microbial transformation by Cladosporium sp. to produce active intermediates, which include 7-hydroxy cholesterol, 20-droxyl-16alpha,17alpha epoxypregna-4-dien-3-one, 7-ketocholesterol, and 7-droxyl-16alpha,17alpha epoxypregna-4-dien-3,20-dione. Under the optimum conditions, the yields of product 3 and product 4 were 20.58 and 17.42%, respectively, higher than that prior to the optimization. The transformation rate increased significantly under the optimum fermentation conditions. This study describes an efficient, rapid, and inexpensive biotransformation system for the production of active pharmaceutical intermediates.

AB - Next generation sequence data were generated and used to assemble the complete plastomes of the holotype of Membranoptera weeksiae, the neotype (designated here) of M. tenuis, and a specimen examined by Kylin in making the new combination M. platyphylla. The three plastomes were similar in gene content and length and showed high gene synteny to Calliarthron, Grateloupia, Sporolithon, and Vertebrata. Sequence variation in the plastome coding regions were 0.89% between M. weeksiae and M. tenuis, 5.14% between M. weeksiae and M. platyphylla, and 5.18% between M. tenuis and M. platyphylla. We were unable to decipher the complete mitogenomes of the three species due to low coverage and structural problems; however, we assembled and analyzed, the cytochrome oxidase I, II, and III loci and found that M. weeksiae and M. tenuis differed in sequence by 1.3%, M. weeksiae and M. platyphylla by 8.4%, and M. tenuis and M. platyphylla by 8.1%. Evaluation of standard marker genes indicated that sequences from the rbcL, RuBisCO spacer, and CO1 genes closely approximated the pair-wise genetic distances observed between the plastomes of the three species of Membranoptera. A phylogenetic tree based on rbcL sequences showed that M. tenuis and M. weeksiae were sister taxa. Short rbcL sequences were obtained from type specimens of M. dimorpha, M. multiramosa, and M. edentata and confirmed their conspecificity with M. platyphylla. The data support the recognition of three species of Membranoptera occurring south of Alaska: M. platyphylla, M. tenuis, and M. weeksiae.

AB - Hexachlorodisilane reacts with diarylmethanones (aryl=C6 H5 , 4-MeC6 H4 , 4-tBuC6 H4 , 4-ClC6 H4 , 4-BrC6 H4 ) to furnish the corresponding tetraarylethylenes in good yields. The reductive conversion requires temperatures of about 160 degrees C and reaction times of 60-72 h. In the initial step, the Lewis-basic carbonyl groups likely generate low-valent [SiCl2 ] as an analogue of [TiCl2 ] in the classical McMurry reaction. The coupling sequence further proceeds via benzopinacolones, which have been isolated as key intermediates. PMID- 27690328 TI - The convergence of senescence and nutrient sensing during lymphocyte ageing. AB - Immunosurveillance requires the migration of lymphocytes and their activation to induce proliferation and effector function. Effective immunity requires an optimal supply of nutrients to lymphocytes. Cells contain nutrient sensing apparatus such as adenosine 5'-monophosphate-activated protein kinase (AMPK) that surveys intracellular ATP levels. Immunity declines during ageing and one possibility is that the energy balance may be altered in old lymphocytes. This paper summarizes recent data identifying a convergence of senescence and nutrient signalling pathways in lymphocytes that inhibit both T cell and natural killer (NK) cell function during ageing. Significantly, these pathways can be inhibited to enhance the activity of these cells. PMID- 27690329 TI - Real-Time Label-Free Monitoring of Nanoparticle Cell Uptake. AB - The surface plasmon resonance technique in combination with whole cell sensing is used for the first time for real-time label-free monitoring of nanoparticle cell uptake. The uptake kinetics of several types of nanoparticles relevant to drug delivery applications into HeLa cells is determined. The cell uptake of the nanoparticles is confirmed by confocal microscopy. The cell uptake of silica nanoparticles and polyethylenimine-plasmid DNA polyplexes is studied as a function of temperature, and the uptake energies are determined by Arrhenius plots. The phase transition temperature of the HeLa cell membrane is detected when monitoring cell uptake of silica nanoparticles at different temperatures. The HeLa cell uptake of the mesoporous silica nanoparticles is energy-independent at temperatures slightly higher than the phase transition temperature of the HeLa cell membrane, while the uptake of polyethylenimine-DNA polyplexes is energy dependent and linear as a function of temperature with an activation energy of Ea = 62 +/- 7 kJ mol-1 = 15 +/- 2 kcal mol-1 . The HeLa cell uptake of red blood cell derived extracellular vesicles is also studied as a function of the extracellular vesicle concentration. The results show a concentration dependent behavior reaching a saturation level of the extracellular vesicle uptake by HeLa cells. PMID- 27690330 TI - Mapping of a FEB3 homologous febrile seizure locus on mouse chromosome 2 containing candidate genes Scn1a and Scn3a. AB - Febrile seizures (FS) are the most common seizure type in children. Recurrent FS are a risk factor for developing temporal lobe epilepsy later in life and are known to have a strong genetic component. Experimental FS (eFS) can be elicited in mice by warm-air induced hyperthermia. We used this model to screen the chromosome substitution strain (CSS) panel derived from C57BL/6J and A/J for FS susceptibility and identified C57BL/6J-Chr2A /NaJ (CSS2), as the strain with the strongest FS susceptibility phenotype. The aim of this study was to map FS susceptibility loci and select candidate genes on mouse chromosome 2. We generated an F2 population by intercrossing the hybrids (F1 ) that were derived from CSS2 and C57BL/6J mice. All CSS2-F2 individuals were genotyped and phenotyped for eFS susceptibility, and QTL analysis was performed. Candidate gene selection was based on bioinformatics analyses and differential brain expression between CSS2 and C57BL/6J strains determined by microarray analysis. Genetic mapping of the eFS susceptibility trait identified two significant loci: FS-QTL2a (LOD-score 3.6) and FS-QTL2b (LOD-score 6.2). FS-QTL2a contained 44 genes expressed in the brain at post natal day 14. Four of these (Arl6ip6, Cytip, Fmnl2 Ifih1) contained a non-synonymous SNP comparing CSS2 and C57BL/6J, six genes (March7, Nr4a2, Gpd2, Grb14, Scn1a, Scn3a) were differentially expressed between these strains. A region within FS-QTL2a is homologous to the human FEB3 locus. The fact that we identify mouse FS-QTL2a with high FEB3 homology is strong support for the validity of the eFS mouse model to study genetics of human FS. PMID- 27690331 TI - Could metformin be used in patients with diabetes and advanced chronic kidney disease? AB - Diabetes is an important cause of end stage renal failure worldwide. As renal impairment progresses, managing hyperglycaemia can prove increasingly challenging, as many medications are contra-indicated in moderate to severe renal impairment. Whilst evidence for tight glycaemic control reducing progression to renal failure in patients with established renal disease is limited, poor glycaemic control is not desirable, and is likely to lead to progressive complications. Metformin is a first-line therapy in patients with Type 2 diabetes, as it appears to be effective in reducing diabetes related end points and mortality in overweight patients. Cessation of metformin in patients with progressive renal disease may not only lead to deterioration in glucose control, but also to loss of protection from cardiovascular disease in a cohort of patients at particularly high risk. We advocate the need for further study to determine the role of metformin in patients with severe renal disease (chronic kidney disease stage 4-5), as well as patients on dialysis, or pre-/peri-renal transplantation. We explore possible roles of metformin in these circumstances, and suggest potential key areas for further study. PMID- 27690332 TI - Validation and application of a nondestructive and contactless method for rheological evaluation of biomaterials. AB - Hydrogels are extensively used for tissue engineering, cell therapy or controlled release of bioactive factors. Nondestructive techniques that can follow their viscoelastic properties during polymerization, remodeling, and degradation are needed, since these properties are determinant for their in vivo efficiency. In this work, we proposed the viscoelastic testing of bilayered materials (VeTBiM) as a new method for nondestructive and contact-less mechanical characterization of soft materials. The VeTBiM method measures the dynamic displacement response of a material, to a low amplitude vibration in order to characterize its viscoelastic properties. We validated VeTBiM by comparing data obtained on various agar and chitosan hydrogels with data from rotational rheometry, and compression tests. We then investigated its potential to follow the mechanical properties of chitosan hydrogels during gelation and in the presence of papain and lysozyme that induce fast or slow enzymatic degradation. Due to this nondestructive and contactless approach, samples can be removed from the instrument and stored in different conditions between measurements. VeTBiM is well adapted to follow biomaterials alone or with cells, over long periods of time. This new method will help in the fine tuning of the mechanical properties of biomaterials used for cell therapy and tissue engineering. (c) 2016 Wiley Periodicals, Inc.

AB - A multicomponent metallic glass (MG) with highly efficient and anomalous durability for catalyzing water splitting is reported. The outstanding performance of the MG catalyst contributed by self-optimized active sites originates from the intrinsic chemical heterogeneity and selective dealloying on the disordered surface; thus, a new mechanism for improving the durability of catalysts is uncovered. PMID- 27690334 TI - Human umbilical cord derivatives regenerate intervertebral disc. AB - Intervertebral disc (IVD) degeneration is characterized by the loss of nucleus pulposus (NP), which is a common cause for lower back pain. Although, currently, there is no cure for the degenerative disc disease, stem cell therapy is increasingly being considered for its treatment. In this study, we investigated the feasibility and efficacy of human umbilical cord mesenchymal stem cells (MSCs) and chondroprogenitor cells (CPCs) derived from those cells to regenerate damaged IVD in a rabbit model. Transplanted cells survived, engrafted and dispersed into NP in situ. Significant improvement in the histology, cellularity, extracellular matrix proteins, and water and glycosaminoglycan contents in IVD recipients of CPCs was observed compared to MSCs. In addition, IVDs receiving CPCs exhibited higher expression of NP-specific human markers, SOX9, aggrecan, collagen 2, FOXF1 and KRT19. The novelty of the study is that in vitro differentiated CPCs derived from umbilical cord MSCs, demonstrated far greater capacity to regenerate damaged IVDs, which provides basis and impetus for stem cell based clinical studies to treat degenerative disc disease.

AB - Developing new synthetic methods for the controlled synthesis of Pt-based or non Pt nanocatalysts with low or no Pt loading to facilitate sluggish cathodic oxygen reduction reaction (ORR) and organics oxidation reactions is the key in the development of fuel-cell technology. Various nanoparticles (NPs), with a range of size, shape, composition, and structure, have shown good potential to catalyze the sluggish cathodic and anodic reactions. In contrast to NPs, one-dimensional (1D) nanomaterials such as nanowires (NWs), and nanotubes (NTs), exhibit additional advantages associated with their anisotropy, unique structure, and surface properties. The prominent characteristics of NWs and NTs include fewer lattice boundaries, a lower number of surface defect sites, and easier electron and mass transport for better electrocatalytic activity and lower vulnerability to dissolution, Ostwald ripening, and aggregation than Pt NPs for enhanced stability. An overview of recent advances in tuning 1D nanostructured Pt-based, Pd-based, or 1D metal-free nanomaterials as advanced electrocatalysts is provided here, for boosting fuel-cell reactions with high activity and stability, including the oxygen reduction reaction (ORR), methanol oxidation reaction (MOR), and ethanol oxidation reaction (EOR). After highlighting the different strategies developed so far for the synthesis of Pt-based 1D nanomaterials with controlled size, shape, and composition, special emphasis is placed on the rational design of diverse NWs and NTs catalysts such as Pt-based NWs or NTs, non-Pt NTs, and carbon NTs with molecular engineering, etc. for enhancing the ORR, MOR, and EOR. Finally, some perspectives are highlighted on the development of more efficient fuel-cell electrocatalysts featuring high stability, low cost, and enhanced performance, which are the key factors in accelerating the commercialization of fuel-cell technology. PMID- 27690336 TI - Bioprocess development workflow: Transferable physiological knowledge instead of technological correlations. AB - Microbial bioprocesses need to be designed to be transferable from lab scale to production scale as well as between setups. Although substantial effort is invested to control technological parameters, usually the only true constant parameter is the actual producer of the product: the cell. Hence, instead of solely controlling technological process parameters, the focus should be increasingly laid on physiological parameters. This contribution aims at illustrating a workflow of data life cycle management with special focus on physiology. Information processing condenses the data into physiological variables, while information mining condenses the variables further into physiological descriptors. This basis facilitates data analysis for a physiological explanation for observed phenomena in productivity. Targeting transferability, we demonstrate this workflow using an industrially relevant Escherichia coli process for recombinant protein production and substantiate the following three points: (1) The postinduction phase is independent in terms of productivity and physiology from the preinduction variables specific growth rate and biomass at induction. (2) The specific substrate uptake rate during induction phase was found to significantly impact the maximum specific product titer. (3) The time point of maximum specific titer can be predicted by an easy accessible physiological variable: while the maximum specific titers were reached at different time points (19.8 +/- 7.6 h), those maxima were reached all within a very narrow window of cumulatively consumed substrate dSn (3.1 +/- 0.3 g/g). Concluding, this contribution provides a workflow on how to gain a physiological view on the process and illustrates potential benefits. (c) 2016 American Institute of Chemical Engineers Biotechnol.

AB - The skull and pelvis have been used for the determination of sex for unknown human remains. However, in forensic cases where skeletal remains often exhibit postmortem damage and taphonomic changes the patella may be used for the determination of sex as it is a preservationally favoured bone. The goal of the present research was to derive discriminant function equations from the patella for estimation of sex from a contemporary Spanish population. Six parameters were measured on 106 individuals (55 males and 51 females), ranging in age from 22 to 85 years old, from the Granada Osteological Collection. The statistical analyses showed that all variables were sexually dimorphic. Discriminant function score equations were generated for use in sex determination. The overall accuracy of sex classification ranged from 75.2% to 84.8% for the direct method and 75.5% 83.8% for the stepwise method. When the South African White discriminant functions were applied to the Spanish sample they showed high accuracy rates for sexing female patellae (90%-95.9%) and low accuracy rates for sexing male patellae (52.7%-58.2%). When the South African Black discriminant functions were applied to the Spanish sample they showed high accuracy rates for sexing male patellae (90.9%) and low accuracy rates for sexing female patellae (70%-75.5%). The patella was shown to be useful for sex determination in the contemporary Spanish population. PMID- 27690338 TI - Cardiovascular pharmacotherapy. PMID- 27690339 TI - Echo and natriuretic peptide guided therapy improves outcome and reduces worsening renal function in systolic heart failure: An observational study of 1137 outpatients. AB - BACKGROUND: B-type natriuretic peptide (BNP) and echocardiography are potentially useful adjunct to guide management of patients with chronic heart failure (HF).Thus, the aim of this retrospective, multicenter study was to compare outcomes and renal function in outpatients with chronic HF with reduced ejection fraction (HFrEF) who underwent an echo and BNP guided or a clinically driven protocol for follow-up. METHODS AND RESULTS: In 1137 consecutive outpatients, management was guided according to echo-Doppler signs of elevated left ventricular filling pressure and BNP levels conforming to the protocol of the Network Labs Ultrasound (NEBULA) in HF Study Group in 570 (mean EF=30%), while management was clinically driven based on the institutional protocol of the HF Unit of the Cardiovascular and Thoracic Department in 567 (mean EF=33%). Propensity score, matching several confounding baseline variables, was used to match pairs based on treatment strategy. The median follow-up was 37.4months. After propensity matching, a lower incidence of death (HR 0.45, 95%CI: 0.30-0.67, p<0.0001), and death or worsening renal function (HR 0.49, 95%CI 0.36-0.67, p<0.0001) was apparent in echo-BNP-guided group compared to clinically-guided group. Worsening of renal function (>=0.3mg/dl increase in serum creatinine) was observed in 9.8% of echo-BNP-guided group and in 21.4% of clinical assessed group (p<0.0001). The daily dose of loop diuretics did not change in echo-BNP-guided group, while it increased in 65% of patients in clinically-guided group (p<0.0001). CONCLUSIONS: Echo and BNP guided management may improve the outcome and reduce worsening of renal function in outpatients with chronic HFrEF. PMID- 27690340 TI - Gastrointestinal complications associated with catheter ablation for atrial fibrillation. AB - Atrial fibrillation is the most common arrhythmia in the United States. With the ageing population, the incidence and prevalence of atrial fibrillation are on the rise. Catheter ablation of atrial fibrillation is a widely accepted treatment modality in patients with drug refractory symptomatic paroxysmal or persistent atrial fibrillation. The close proximity to the left atrium posterior wall makes the thermosensitive esophagus a potential site of injury during catheter ablation of AF leading to various gastrointestinal complications. The major gastrointestinal complications associated with catheter ablation include atrioesophageal fistula, gastroparesis, esophageal thermal lesions and esophageal ulcers. Multiple studies, case reports and series have described these complications with various catheter ablation techniques such as radiofrequency, cryoenergy and high frequency focused ultrasound energy ablation. This review addresses the gastrointestinal complications after AF ablation procedures and aims to provide the clinicians with an overview of clinical presentation, etiology, pathogenesis, prevention and management of these conditions. PMID- 27690341 TI - Hormonal receptors in lung adenocarcinoma: expression and difference in outcome by sex. AB - BACKGROUND: Lung cancer seems to have different epidemiological, biomolecular and clinical characteristics in females than in males, with a better prognosis for women. The aim of the study is to determine gender differences in lung adenocarcinoma in terms of androgen (AR), estrogen (ER)alpha and progesterone (PgR) receptors expression and their impact on outcome. RESULTS: Overall survival was significantly better in ERalpha and in PgR positive lung adenocarcinoma patients (median survival 45 vs. 19 months).Eight out of 62 patients showed positive expression of nuclear (n) AR and 18 of cytoplasmic (c) AR with a significantly better survival (49 vs. 19 and 45 vs. 19 months, respectively). There was a significant difference in survival between patients with vs. without c-AR expression (30 vs. 17 months). Finally, in the subgroup of women, median survival was greater in positive expression of c-AR than for women with negative c-AR (45 vs. 21 months). MATERIALS AND METHODS: We conducted an analysis on a cohort of 62 patients with advanced NSCLC treated at our institution. We investigated the immunohistochemical expression of n/c AR, ERalpha and PgR in 62 NSCLC and we correlated it with patients' clinic-pathologic characteristics and with prognosis. CONCLUSIONS: Our results showed that the positive expression of one hormonal receptor could represent a prognostic factor.Furthermore our study suggests that AR should become object of close examination in a larger series of lung adenocarcinoma patients, also for selection of the patients with best prognosis that can perform more chemotherapy lines. PMID- 27690342 TI - Tyrosine kinase LYN is an oncotarget in human cervical cancer: A quantitative proteomic based study. AB - Cervical cancer is one of the most common malignant tumor in women. The mechanisms of cervical cancer are intricate and have not been fully understood. Therefore, we employed iTRAQ to obtain novel proteins profile which participates in the tumor oncogenesis of cervical cancer. 3300 proteins were identified aberrantly expressed in cervical cancer, and western bolt was performed to validate the results of iTRAQ. Then, we selected LYN for further study. Immunohistochemistry identified that LYN expression was significantly increased in cervical cancer tissues than that in cancer adjacent normal cervical tissues and normal cervical tissues. The increased LYN expression was significantly correlated with cancer differentiation and FIGO stage. Silencing LYN inhibited cell proliferation, migration and invasion, conversely, overexpression LYN promoted cell proliferation, migration and invasion. In terms of mechanism, LYN could also promote cervical cancer cells metastasis through activating IL-6/STAT3 pathway. In vivo study, overexpression LYN promoted tumor growth, meanwhile knockdown LYN inhibited tumor growth. These results indicate that LYN tyrosine kinase is an oncogenic gene and can serve as a novel target for cervical cancer research and therapy. PMID- 27690343 TI - Should all breast cancer patients with four or more positive lymph nodes who underwent modified radical mastectomy be treated with postoperative radiotherapy? A population-based study. AB - Postmastectomy radiotherapy (PMRT) has become a standard adjuvant postoperative therapy for breast cancer patients with four or more positive lymph nodes. However, some studies have demonstrated that some subgroups of the breast cancer patients with four or more positive lymph nodes did not benefit substantially from PMRT. Therefore, it is of great necessity to identify whether all breast cancer patients with four or more positive lymph nodes who underwent modified radical mastectomy be treated with PMRT. In our study, we first established a prognostic model using the Surveillance Epidemiology and End Results (SEER) database between 1998 and 2001. Univariate and multivariate Cox models were used to assess the prognostic factors, and five risk factors individually associated with prognosis including AJCC stage, AJCC T, Grade, ER status, PR status. Prognostic index of PMRT were defined as the number of risk factor (NRF). The NRF scores correlated well with overall survival of PMRT even if the patients were in the sub-poor prognosis group. Then the prognostic model was validated using the SEER database between 2006 and 2009, and the same results were obtained. In conclusion, different from others studies, our study demonstrated that all patients with four or more positive lymph nodes after modified radical mastectomy need to be treated with PMRT ever if the patients belonged to AJCC T4 in a poor prognosis group. PMID- 27690344 TI - The effect of the severity of obstructive sleep apnea syndrome on telomere length. AB - Aging is associated with an increase in the prevalence of obstructive sleep apnea syndrome (OSAS) as well as the shortening of telomeres. It is known that OSAS related factors are stimuli that can contribute to the acceleration of cellular senescence. Thus, the present study aimed to compare the leukocyte telomere length (LTL) between OSAS patients and controls, as well as to verify the correlation between LTL and sleep parameters. We used DNA extracted of 928 individuals from EPISONO to measure the LTL by the quantitative real-time polymerase chain reaction. All individuals were subjected to one full-night polysomnography. LTL was significantly shorter in OSAS patients compared to controls. The results showed negative correlations between LTL and the following variables: apnea-hypopnea index, respiratory disturbance index, desaturation index and wake after sleep onset. LTL was positively correlated with sleep efficiency, total sleep time, basal, minimum and maximum oxygen saturation. Lastly, it was observed that OSAS severity was associated with shorter LTL even after adjusting for sex, age, years of schooling, body mass index, diabetes, stroke and heart attack. In conclusion, our study indicates the presence of an association between LTL and OSAS and a significant impact of severity of OSAS in telomeres shortening. PMID- 27690346 TI - Preventing probe induced topography correlated artifacts in Kelvin Probe Force Microscopy. AB - Kelvin Probe Force Microscopy (KPFM) on samples with rough surface topography can be hindered by topography correlated artifacts. We show that, with the proper experimental configuration and using homogeneously metal coated probes, we are able to obtain amplitude modulation (AM) KPFM results on a gold coated sample with rough topography that are free from such artifacts. By inducing tip inhomogeneity through contact with the sample, clear potential variations appear in the KPFM image, which correlate with the surface topography and, thus, are probe induced artifacts. We find that switching to frequency modulation (FM) KPFM with such altered probes does not remove these artifacts. We also find that the induced tip inhomogeneity causes a lift height dependence of the KPFM measurement, which can therefore be used as a check for the presence of probe induced topography correlated artifacts. We attribute the observed effects to a work function difference between the tip and the rest of the probe and describe a model for such inhomogeneous probes that predicts lift height dependence and topography correlated artifacts for both AM and FM-KPFM methods. This work demonstrates that using a probe with a homogeneous work function and preventing tip changes is essential for KPFM on non-flat samples. From the three investigated probe coatings, PtIr, Au and TiN, the latter appears to be the most suitable, because of its better resistance against coating damage.

AB - BACKGROUND & AIMS: Combined therapy inhibiting EGFR and VEGF pathways is becoming a promising therapy in the treatment of advanced non-small-cell lung cancer (NSCLC), however, with controversy. The study aims to compare the efficacy of combined inhibition therapy versus control therapy (including placebo, single EGFR inhibition and single VEGF inhibition) in patients with advanced NSCLC. MATERIALS AND METHODS: An adequate literature search in EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), American Society of Clinical Oncology (ASCO) and European Society of Medical Oncology (ESMO) was conducted. Phase II or III randomized controlled trials (RCTs) that compared effectiveness between combined inhibition therapy and control therapy in patients with advanced NSCLC were eligible. The endpoint was overall response rate (ORR), progression free survival (PFS) and overall survival (OS). RESULTS: Sixteen phase II or III RCTs involving a total of 7,109 patients were included. The results indicated that the combined inhibition therapy significantly increased the ORR (OR = 1.59, 95% CI = 1.36-1.87, p<0.00001; I2 = 36%) when compared to control therapy. In the subgroup analysis, the combined inhibition therapy clearly increased the ORR (OR = 2.04, 95% CI = 1.60-2.60, p<0.00001; I2 = 0%) and improved the PFS (HR = 0.78, 95% CI = 0.71-0.85, p<0.00001;I2 = 0%) when compared with the placebo, and similar results was detected when compared with the single EGFR inhibition in terms of ORR (OR = 1.39, 95% CI = 1.12-1.74, p = 0.003; I2 = 30%) and PFS (HR = 0.73, 95% CI = 0.67 0.81, p<0.0001; I2 = 50%). No obvious difference was found between the combined inhibition therapy and single VEGF inhibition in term of ORR, however, combined inhibition therapy significantly decreased the PFS when compared to the single VEGF inhibition therapy (HR = 1.70, 95% CI = 1.34-2.17, p<0.0001; I2 = 50%). Besides, no significant difference was observed between the combined inhibition therapy and control therapy in term of OS (including placebo, single EGFR inhibition and single VEGF inhibition) (HR = 0.98, 95% CI = 0.92-1.04, p = 0.41; I2 = 0%). CONCLUSIONS: Combined inhibition therapy was superior to placebo and single EGFR inhibition in terms of ORR, PFS for advanced NSCLC, however, no statistical difference were found in term of OS. Besides, combined inhibition therapy was not superior to single VEGF inhibition in terms of ORR, PFS and OS. Therefore, combined inhibition therapy is recommended to treat advanced NSCLC patients.

AB - An annular dark field (ADF) detector was placed beneath a specimen in a field emission scanning electron microscope operated at 30kV to calibrate detector response to incident beam current, and to create transmission images of gold nanoparticles on silicon nitride (SiN) substrates of various thicknesses. Based on the linear response of the ADF detector diodes to beam current, we developed a method that allowed for direct determination of the percentage of that beam current forward scattered to the ADF detector from the sample, i.e. the transmitted electron (TE) yield. Collection angles for the ADF detector region were defined using a masking aperture above the detector and were systematically varied by changing the sample to detector distance. We found the contrast of the nanoparticles, relative to the SiN substrate, decreased monotonically with decreasing inner exclusion angle and increasing substrate thickness. We also performed Monte Carlo electron scattering simulations, which showed quantitative agreement with experimental contrast associated with the nanoparticles. Together, the experiments and Monte Carlo simulations revealed that the decrease in contrast with decreasing inner exclusion angle was due to a rapid increase in the TE yield of the low atomic number substrate. Nanoparticles imaged at low inner exclusion angles (<150mrad) and on thick substrates (>50nm) showed low image contrast in their centers surrounded by a bright high-contrast halo on their edges. This complex image contrast was predicted by Monte Carlo simulations, which we interpreted in terms of mixing of the nominally bright field (BF) and ADF electron signals. Our systematic investigation of inner exclusion angle and substrate thickness effects on ADF t-SEM imaging provides fundamental understanding of the contrast mechanisms for image formation, which in turn suggest practical limitations and optimal imaging conditions for different substrate thicknesses. PMID- 27690348 TI - EBSD spatial resolution for detecting sigma phase in steels. AB - The spatial resolution of the electron backscatter diffraction signal is explored by Monte Carlo simulation for the sigma phase in steel at a typical instrumental set-up. In order to estimate the active volume corresponding to the diffracted electrons, the fraction of the backscattered electrons contributing to the diffraction signal was inferred by extrapolating the Kikuchi pattern contrast measured by other authors, as a function of the diffracted electron energy. In the resulting estimation, the contribution of the intrinsic incident beam size and the software capability to deconvolve patterns were included. A strong influence of the beam size on the lateral resolution was observed, resulting in 20nm for the aperture considered. For longitudinal and depth directions the resolutions obtained were 75nm and 16nm, respectively. The reliability of this last result is discussed in terms of the survey of the last large-angle deflection undergone by the backscattered electrons involved in the diffraction process. Bearing in mind the mean transversal resolution found, it was possible to detect small area grains of sigma phase by EBSD measurements, for a stabilized austenitic AISI 347 stainless steel under heat treatments, simulating post welding (40h at 600 degrees C) and aging (284h at 484 degrees C) effects-as usually occurring in nuclear reactor pressure vessels. PMID- 27690349 TI - Nonlinear Hebbian Learning as a Unifying Principle in Receptive Field Formation. AB - The development of sensory receptive fields has been modeled in the past by a variety of models including normative models such as sparse coding or independent component analysis and bottom-up models such as spike-timing dependent plasticity or the Bienenstock-Cooper-Munro model of synaptic plasticity. Here we show that the above variety of approaches can all be unified into a single common principle, namely nonlinear Hebbian learning. When nonlinear Hebbian learning is applied to natural images, receptive field shapes were strongly constrained by the input statistics and preprocessing, but exhibited only modest variation across different choices of nonlinearities in neuron models or synaptic plasticity rules. Neither overcompleteness nor sparse network activity are necessary for the development of localized receptive fields. The analysis of alternative sensory modalities such as auditory models or V2 development lead to the same conclusions. In all examples, receptive fields can be predicted a priori by reformulating an abstract model as nonlinear Hebbian learning. Thus nonlinear Hebbian learning and natural statistics can account for many aspects of receptive field formation across models and sensory modalities.

AB - BACKGROUND: Like any child, children with Down syndrome (DS) affect the lives of their families. Most studies focus on the adaptation of parents and families of young children with DS, while relatively few studies include the perspective of fathers. AIMS: To determine 1) whether mothers and fathers of 11 to 13-year-olds with DS differ from reference parents in health related quality of life (HRQoL) and family functioning, and 2) whether HRQoL in parents of children with DS changes over time, from when the child was 6-8 years old to when the child was 11 13 years old. METHODS: 80 mothers and 44 fathers completed HRQoL and family functioning questionnaires. 58 parents (53 mothers) had completed the HRQoL questionnaire in a previous study. RESULTS: Mothers differed from reference mothers in one HRQoL-domain (Sexuality), while fathers' HRQoL did not significantly differ from reference fathers. Both mothers and fathers scored in the (sub)clinical range more frequently than reference parents in Total family functioning, and in the domains Partner relation and Social network. Furthermore, fathers scored in the (sub)clinical range more frequently than reference parents in Responsiveness and Organization. HRQoL showed no significant change over time. CONCLUSIONS AND IMPLICATIONS: Our findings indicate frequent family functioning problems but few HRQoL problems in parents and families of children with DS. In offering care, a family based approach with special attention for partner relation and social functioning is needed. PMID- 27690351 TI - Disrupted latent decision processes in medication-free pediatric OCD patients. AB - BACKGROUND: Decision-making in Obsessive Compulsive Disorder has typically been investigated in the adult population. Computational approaches have recently started to get integrated into these studies. However, decision-making research in pediatric OCD populations is scarce. METHODS: We investigated latent decision processes in 21 medication-free pediatric OCD patients and 23 healthy control participants. We hypothesized that OCD patients would be more cautious and less efficient in evidence accumulation than controls in a two alternative forced choice (2AFC) task. RESULTS: Pediatric OCD patients were less efficient than controls in accumulating perceptual evidence and showed a tendency to be more cautious. In comparison to post-correct decisions, OCD patients increased decision thresholds after erroneous decisions, whereas healthy controls decreased decision thresholds. These changes were coupled with weaker evidence accumulation after errors in both groups. LIMITATIONS: The small sample size limited the power of the study. CONCLUSIONS: Our results demonstrate poorer decision-making performance in pediatric OCD patients at the level of latent processes, specifically in terms of evidence accumulation. PMID- 27690352 TI - Reconsidering the definition of Major Depression based on Collaborative Psychiatric Epidemiology Surveys. AB - BACKGROUND: Diagnostic definitions for depressive disorders remain a debated topic, despite their central role in clinical practice and research. We use both recent evidence and nationally representative data to derive an empirically-based modification of DSM-IV/-5 Major Depressive Disorder (MDD). METHOD: A modified MDD diagnosis was derived by analyzing data from Collaborative Psychiatric Epidemiology Surveys, a multistage probability sample of adults (n=20 013; age >= 18 years) in coterminous USA, Alaska and Hawaii. The old and the newly suggested MDD definitions were compared for their associated disability (WHO Disability Assessment Schedule and number of disability days in past month), suicide attempt, and other covariates. RESULTS: Our data-driven definition for major depression was "lack of interest to all or most things" plus four other symptoms from the set {weight gain, weight loss, insomnia, psychomotor retardation, fatigue, feelings of worthlessness, diminished ability to think/concentrate, suicidal ideation/attempt}. The new definition captured all the disability implied by MDD and excluded cases that showed no greater disability than the general population nor increased risk of suicide attempts. The lifetime prevalence of the new diagnosis was 14.7% (95% CI=14-15.4%) of the population, slightly less than for the old definition (16.4%; CI=15.4-17.3%). LIMITATIONS: Only conservative modifications of MDD could be studied, because of restrictions in the symptom data. CONCLUSIONS: With only small adjusting, the new definition for major depression may be more clinically relevant than the old one, and could serve as a conservative replacement for the old definition. PMID- 27690353 TI - Fixed-dose versus separate drug combinations for antihypertensive treatment: literature review. AB - INTRODUCTION: Hypertension requires effective interventions to reduce cardiovascular morbidity and mortality. Drug therapies have achieved optimal blood pressure levels in affected patients. Recent clinical guidelines suggest drug combinations a fact that has led to the development of various fixed-dose combinations. OBJECTIVE: To find the best available evidence about the effectiveness of antihypertensive drugs in fixed-dose combinations compared with separate dose combinations for blood pressure control, treatment adherence and reducing cardiovascular morbidity and mortality. METHODS: Systematic literature search of the best evidence available in the following databases was performed: MEDLINE/PubMed, LILACS, Cochrane and institutional publications of WHO and PAHO. RESULTS: Two meta-analyses comparing the two combinations were found, in both studies medication compliance was evaluated, no control of blood pressure or effects on cardiovascular events was assessed. Both studies are of very low quality of evidence due to limitations in search methodology, suboptimal quality of the included studies and heterogeneity of the analyzed variables. WHO drug use policies for antihypertensive drugs do not suggest fixed-drug combinations. These combinations are not included in Chile's national drug formulary. CONCLUSION: Well-designed studies are required to demonstrate the effectiveness of antihypertensive drugs in fixed-dose combination compared with separate dose combinations for controlling blood pressure, treatment adherence and reducing cardiovascular morbidity and mortality.

AB - Latin Americans arguably represent the largest recently admixed populations in the world. This reflects a history of massive settlement by immigrants (mostly Europeans and Africans) and their variable admixture with Natives, starting in 1492. This process resulted in the population of Latin America showing an extensive genetic and phenotypic diversity. Here we review how genetic analyses are being applied to examine the demographic history of this population, including patterns of mating, population structure and ancestry. The admixture history of Latin America, and the resulting extensive diversity of the region, represents a natural experiment offering an advantageous setting for genetic association studies. We review how recent analyses in Latin Americans are contributing to elucidating the genetic architecture of human complex traits. PMID- 27690356 TI - Impact of Malocclusion on the Quality of Life of Brazilian Adolescents: A Population-Based Study. AB - The objective of this study was to evaluate the impact of malocclusion on the quality of life (QOL) of adolescents in Brazil. We carried out a cross-sectional study in a sample population of 1015 schoolchildren aged 12 to 15 years from Sao Luis, Maranhao, Brazil. The explanatory variable was malocclusion, evaluated on the basis of the normative need or the adolescent's self-perceived need for dental treatment. Normative need for dental treatment was determined by professional diagnosis, made on the basis of Angle's classification, the Dental Aesthetic Index, and other morphological deviations (e.g., posterior crossbite, posterior open bite, and deep overbite). We analyzed the impact of malocclusion on the QOL using the Portuguese version of the Oral Health Impact Profile-14. Associations were estimated by using the prevalence ratio (PR) in Poisson regression analysis, with hierarchized modeling. An alpha of 5% was adopted as the criterion for statistical significance. The QOL of adolescents was impacted by malocclusion, classified by a normative need for treatment according to the Dental Aesthetic Index (PR = 1.27; 95% confidence interval [CI] = 1.03-1.56) or by the self-perceived need for treatment (PR = 2.54; 95% CI = 1.81-3.56). Certain sociodemographic variables, including the head of the family (PR = 1.52; 95% CI = 1.02-2.23), greater educational level of the head of the family (PR = 0.32; 95% CI = 0.17-0.61), and female sex (PR = 1.40; 95% CI = 1.05-1.89), had negative associations with QOL. We conclude that malocclusion has a negative impact on the QOL of adolescents, associated with socioeconomic conditions and the cosmetic effects of malocclusion. PMID- 27690357 TI - Motility and microtubule depolymerization mechanisms of the Kinesin-8 motor, KIF19A. AB - The kinesin-8 motor, KIF19A, accumulates at cilia tips and controls cilium length. Defective KIF19A leads to hydrocephalus and female infertility because of abnormally elongated cilia. Uniquely among kinesins, KIF19A possesses the dual functions of motility along ciliary microtubules and depolymerization of microtubules. To elucidate the molecular mechanisms of these functions we solved the crystal structure of its motor domain and determined its cryo-electron microscopy structure complexed with a microtubule. The features of KIF19A that enable its dual function are clustered on its microtubule-binding side. Unexpectedly, a destabilized switch II coordinates with a destabilized L8 to enable KIF19A to adjust to both straight and curved microtubule protofilaments. The basic clusters of L2 and L12 tether the microtubule. The long L2 with a characteristic acidic-hydrophobic-basic sequence effectively stabilizes the curved conformation of microtubule ends. Hence, KIF19A utilizes multiple strategies to accomplish the dual functions of motility and microtubule depolymerization by ATP hydrolysis. PMID- 27690358 TI - Formulation and communication of evaluative forensic science expert opinion-A GHEP-ISFG contribution to the establishment of standards. AB - Communicating and interpreting genetic evidence in the administration of justice is currently a matter of great concern, due to the theoretical and technical complexity of the evaluative reporting and large difference in expertise between forensic experts and law professionals. A large number of initiatives have been taken trying to bridge this gap, contributing to the education of both parties. Results however have not been very encouraging, as most of these initiatives try to cope globally with the problem, addressing simultaneously theoretical and technical approaches which are in a quite heterogeneous state of development and validation. In consequence, the extension and complexity of the resulting documents disheartens their study by professionals (both jurists and geneticists) and makes a consensus very hard to reach even among the genetic experts' community. Here we propose a 'back-to-basics', example-driven approach, in which a model report for the two most common situations faced by forensic laboratories is presented. We do hope that this strategy will provide a solid basis for a stepwise generalisation. PMID- 27690359 TI - Safely Discharging Infants with Bronchiolitis from an Emergency Department: A Five Step Guide for Pediatricians. AB - Recent publications have established the pulse oxygen saturation (SpO2) threshold of 90% for the hospitalization and discharge of infant patients with bronchiolitis. However, there is no clear recommendation regarding the Emergency Department (ED) observation period necessary before allowing safe home discharge for patients with SpO2 above 90%-92%. Our primary aims were to evaluate the risk factors associated with delayed desaturation in infants with SpO2 >= 92% on arrival at the ED as well as the ED observation period necessary before allowing safe home discharge. A secondary aim was to identify the risk factors for ED readmission. Of 581 episodes of bronchiolitis in patients < 1 year old admitted to the ED, only 47 (8%) had SpO2 < 92% on arrival there, although 106 (18%) exhibited a delayed desaturation (to < 92%) during ED observation. Female sex, age < 3 months old, ED readmission, more severe initial clinical presentation, and higher pCO2 level (> 6KPa) were risk factors for delayed desaturation with OR varying from 1.7 to 7.5. In patients < 3 months old, mean desaturation occured later than in older patients [6.0 hours (IQR 3.0-14.0) vs. 3.0 hours (IQR 2.0 6.0), P = 0.0018]. In 95% of patients with a delayed desaturation this decrease occurred within 25 hours for patients < 3 months old and within 11 hours for patients >= 3 months old. In patients < 3 months old with respiratory rates above the normal range for their age the desaturation occurred earlier than in patients < 3 months with normal respiratory rates [4.4 hours (IQR 3.0-11.7) vs. 14.6 hours (IQR 7.6-22.2), P = 0.037]. Based on the present study's results, we propose a five step guide for pediatricians on discharging children with bronchiolitis from the ED. By using the threshold of an 11 hour ED observation period for patients >= 3 months old and a 25 hour period for patients < 3 months old we are able to detect 95% of the patients with bronchiolitis who are at risk of delayed desaturation. PMID- 27690360 TI - Exposure to Corticosterone Affects Host Resistance, but Not Tolerance, to an Emerging Fungal Pathogen. AB - Host responses to pathogens include defenses that reduce infection burden (i.e., resistance) and traits that reduce the fitness consequences of an infection (i.e., tolerance). Resistance and tolerance are affected by an organism's physiological status. Corticosterone ("CORT") is a hormone that is associated with the regulation of many physiological processes, including metabolism and reproduction. Because of its role in the stress response, CORT is also considered the primary vertebrate stress hormone. When secreted at high levels, CORT is generally thought to be immunosuppressive. Despite the known association between stress and disease resistance in domesticated organisms, it is unclear whether these associations are ecologically and evolutionary relevant in wildlife species. We conducted a 3x3 fully crossed experiment in which we exposed American toads (Anaxyrus [Bufo] americanus) to one of three levels of exogenous CORT (no CORT, low CORT, or high CORT) and then to either low or high doses of the pathogenic chytrid fungus Batrachochytrium dendrobatidis ("Bd") or a sham exposure treatment. We assessed Bd infection levels and tested how CORT and Bd affected toad resistance, tolerance, and mortality. Exposure to the high CORT treatment significantly elevated CORT release in toads; however, there was no difference between toads given no CORT or low CORT. Exposure to CORT and Bd each increased toad mortality, but they did not interact to affect mortality. Toads that were exposed to CORT had higher Bd resistance than toads exposed to ethanol controls/low CORT, a pattern opposite that of most studies on domesticated animals. Exposure to CORT did not affect toad tolerance to Bd. Collectively, these results show that physiological stressors can alter a host's response to a pathogen, but that the outcome might not be straightforward. Future studies that inhibit CORT secretion are needed to better our understanding of the relationship between stress physiology and disease resistance and tolerance in wild vertebrates. PMID- 27690361 TI - Anchoring of Heterochromatin to the Nuclear Lamina Reinforces Dosage Compensation Mediated Gene Repression. AB - Higher order chromosome structure and nuclear architecture can have profound effects on gene regulation. We analyzed how compartmentalizing the genome by tethering heterochromatic regions to the nuclear lamina affects dosage compensation in the nematode C. elegans. In this organism, the dosage compensation complex (DCC) binds both X chromosomes of hermaphrodites to repress transcription two-fold, thus balancing gene expression between XX hermaphrodites and XO males. X chromosome structure is disrupted by mutations in DCC subunits. Using X chromosome paint fluorescence microscopy, we found that X chromosome structure and subnuclear localization are also disrupted when the mechanisms that anchor heterochromatin to the nuclear lamina are defective. Strikingly, the heterochromatic left end of the X chromosome is less affected than the gene-rich middle region, which lacks heterochromatic anchors. These changes in X chromosome structure and subnuclear localization are accompanied by small, but significant levels of derepression of X-linked genes as measured by RNA-seq, without any observable defects in DCC localization and DCC-mediated changes in histone modifications. We propose a model in which heterochromatic tethers on the left arm of the X cooperate with the DCC to compact and peripherally relocate the X chromosomes, contributing to gene repression. PMID- 27690362 TI - Renal MR angiography and perfusion in the pig using hyperpolarized water. AB - PURPOSE: To study hyperpolarized water as an angiography and perfusion tracer in a large animal model. METHODS: Protons dissolved in deuterium oxide (D2 O) were hyperpolarized in a SPINlab dissolution dynamic nuclear polarization (dDNP) polarizer and subsequently investigated in vivo in a pig model at 3 Tesla (T). Approximately 15 mL of hyperpolarized water was injected in the renal artery by hand over 4-5 s. RESULTS: A liquid state polarization of 5.3 +/- 0.9% of 3.8 M protons in 15 mL of deuterium oxide was achieved with a T1 of 24 +/- 1 s. This allowed injection through an arterial catheter into the renal artery and subsequently high-contrast imaging of the entire kidney parenchyma over several seconds. The dynamic images allow quantification of tissue perfusion, with a mean cortical perfusion of 504 +/- 123 mL/100 mL/min. CONCLUSION: Hyperpolarized water MR imaging was successfully demonstrated as a renal angiography and perfusion method. Quantitative perfusion maps of the kidney were obtained in agreement with literature and control experiments with gadolinium contrast. Magn Reson Med 78:1131-1135, 2017.

The combination of Mn(CO)5 Br with [HN(CH2 CH2 P(Et)2 )2 ] leads to a mixture of cationic and neutral Mn PNP pincer complexes, which enable the reduction of various ester substrates, including aromatic and aliphatic esters as well as diesters and lactones. Notably, related pincer complexes with isopropyl or cyclohexyl substituents showed very low activity. PMID- 27690364 TI - Maximum Bite Force of Edentulous Patients before and after Dental Implant Rehabilitation: Long-Term Follow-Up and Facial Type Influence. AB - PURPOSE: (1) To evaluate patients' long-term maximum bite force (MBF) after rehabilitation with mandibular implant-supported prosthesis, (2) to assess the influence of facial pattern in MBF, and (3) to evaluate the relation between the dominant chewing side and MBF. MATERIALS AND METHODS: Twenty-nine patients were selected. Pre- (T0) and immediate post-rehabilitation (T1) data of MBF were collected. In a follow-up visit 3 to 5 years after rehabilitation (T2), 24 patients participated. The patients were asked about dominant chewing side, and facial pattern was obtained by the initial lateral radiographs. RESULTS: There was statistically significant increase in MBF in T1 - T0 = 5.4 +/- 4.3 kgf, T2 - T1 = 5.5 +/- 6.0 kgf. There was no statistically significant difference in MBF considering facial type, brachyfacial (T0 = 4.4, T1 = 10.7, T2 = 17.6 kgf), mesofacial (T0 = 4.1, T1 = 9.7, T2 = 16.5 kgf), and dolichofacial (T0 = 3.4, T1 = 7.9, T2 = 12.6 kgf). CONCLUSIONS: There was no statistically significant relation between MBF and the dominant chewing side. It can be concluded that mandibular rehabilitation with dental implants improves MBF independent of the facial pattern and dominant chewing side. PMID- 27690366 TI - Rate of rise in diastolic blood pressure influences vascular sympathetic response to mental stress. AB - KEY POINTS: Research indicates that individuals may experience a rise (positive responders) or fall (negative responders) in muscle sympathetic nerve activity (MSNA) during mental stress. In this study, we examined the early blood pressure responses (including the peak, time of peak and rate of rise in blood pressure) to mental stress in positive and negative responders. Negative MSNA responders to mental stress exhibit a more rapid rise in diastolic pressure at the onset of the stressor, suggesting a baroreflex-mediated suppression of MSNA. In positive responders there is a more sluggish rise in blood pressure during mental stress, which appears to be MSNA-driven. This study suggests that whether MSNA has a role in the pressor response is dependent upon the reactivity of blood pressure early in the task. ABSTRACT: Research indicates that individuals may experience a rise (positive responders) or fall (negative responders) in muscle sympathetic nerve activity (MSNA) during mental stress. The aim was to examine the early blood pressure response to stress in positive and negative responders and thus its influence on the direction of change in MSNA. Blood pressure and MSNA were recorded continuously in 21 healthy young males during 2 min mental stressors (mental arithmetic, Stroop test) and physical stressors (cold pressor, handgrip exercise, post-exercise ischaemia). Participants were classified as negative or positive responders according to the direction of the mean change in MSNA during the stressor tasks. The peak changes, time of peak and rate of changes in blood pressure were compared between groups. During mental arithmetic negative responders experienced a significantly greater rate of rise in diastolic blood pressure in the first minute of the task (1.3 +/- 0.5 mmHg s-1 ) compared with positive responders (0.4 +/- 0.1 mmHg s-1 ; P = 0.03). Similar results were found for the Stroop test. Physical tasks elicited robust parallel increases in blood pressure and MSNA across participants. It is concluded that negative MSNA responders to mental stress exhibit a more rapid rise in diastolic pressure at the onset of the stressor, suggesting a baroreflex-mediated suppression of MSNA. In positive responders there is a more sluggish rise in blood pressure during mental stress, which appears to be MSNA-driven. This study suggests that whether MSNA has a role in the pressor response is dependent upon the reactivity of blood pressure early in the task. PMID- 27690365 TI - Mesoscale imaging with cryo-light and X-rays: Larger than molecular machines, smaller than a cell. AB - In the context of cell biology, the term mesoscale describes length scales ranging from that of an individual cell, down to the size of the molecular machines. In this spatial regime, small building blocks self-organise to form large, functional structures. A comprehensive set of rules governing mesoscale self-organisation has not been established, making the prediction of many cell behaviours difficult, if not impossible. Our knowledge of mesoscale biology comes from experimental data, in particular, imaging. Here, we explore the application of soft X-ray tomography (SXT) to imaging the mesoscale, and describe the structural insights this technology can generate. We also discuss how SXT imaging is complemented by the addition of correlative fluorescence data measured from the same cell. This combination of two discrete imaging modalities produces a 3D view of the cell that blends high-resolution structural information with precise molecular localisation data. PMID- 27690368 TI - Hereditary Dopamine Transporter Deficiency Syndrome: Challenges in Diagnosis and Treatment. AB - Hereditary dopamine transporter deficiency syndrome (DTDS) is a neurotransmitter disorder caused by a defect in the neuronal uptake of dopamine. To date, 20 patients are reported in the literature, and we present 2 additional patients with DTDS harboring novel homozygous SLC6A3 gene mutations. Patient A is an 8 month-old male with neonatal-onset hypotonia, who developed orolingual dyskinetic movements and oculogyric crises after 4 months of age, with evolution to status dystonicus episodes. Patient B is a 4-year-old male who also had hypotonia since birth, with additional severe limb contractions and oculogyric crises after the age of 3 months, with a misdiagnosis of epileptic encephalopathy. Both patients had consanguineous parents and similar cerebrospinal fluid (CSF) neurotransmitter profiles with elevated homovanillic acid and increased the ratio of homovanillic acid to 5-hydroxyindoleacetic acid. Diagnostic delay is 4 months, and 3 years 9 months, respectively. Treatment response to levodopa is poor. Early infantile onset progressive dystonia with oculogyric crises, hypotonia, developmental delay, and CSF neurotransmitter profile led to a diagnosis of DTDS in these two patients. Management of hyperkinetic movement disorder, status dystonicus, and feeding difficulties are challenging. Detailed phenotyping of individual patients along with treatment response should provide insight into dopamine homeostasis. PMID- 27690367 TI - Decision Making Impairment: A Shared Vulnerability in Obesity, Gambling Disorder and Substance Use Disorders? AB - INTRODUCTION: Addictions are associated with decision making impairments. The present study explores decision making in Substance use disorder (SUD), Gambling disorder (GD) and Obesity (OB) when assessed by Iowa Gambling Task (IGT) and compares them with healthy controls (HC). METHODS: For the aims of this study, 591 participants (194 HC, 178 GD, 113 OB, 106 SUD) were assessed according to DSM criteria, completed a sociodemographic interview and conducted the IGT. RESULTS: SUD, GD and OB present impaired decision making when compared to the HC in the overall task and task learning, however no differences are found for the overall performance in the IGT among the clinical groups. Results also reveal some specific learning across the task patterns within the clinical groups: OB maintains negative scores until the third set where learning starts but with a less extend to HC, SUD presents an early learning followed by a progressive although slow improvement and GD presents more random choices with no learning. CONCLUSIONS: Decision making impairments are present in the studied clinical samples and they display individual differences in the task learning. Results can help understanding the underlying mechanisms of OB and addiction behaviors as well as improve current clinical treatments. PMID- 27690370 TI - Magnetometry of Individual Polycrystalline Ferromagnetic Nanowires. AB - Ferromagnetic nanowires are finding use as untethered sensors and actuators for probing micro- and nanoscale biophysical phenomena, such as for localized sensing and application of forces and torques on biological samples, for tissue heating through magnetic hyperthermia, and for microrheology. Quantifying the magnetic properties of individual isolated nanowires is crucial for such applications. Dynamic cantilever magnetometry is used to measure the magnetic properties of individual sub-500 nm diameter polycrystalline nanowires of Ni and Ni80 Co20 fabricated by template-assisted electrochemical deposition. The values are compared with bulk, ensemble measurements when the nanowires are still embedded within their growth matrix. It is found that single-particle and ensemble measurements of nanowires yield significantly different results that reflect inter-nanowire interactions and chemical modifications of the sample during the release process from the growth matrix. The results highlight the importance of performing single-particle characterization for objects that will be used as individual magnetic nanoactuators or nanosensors in biomedical applications.

AB - INTRODUCTION: The medicinal plant Actaea racemosa L. (Ranunculaceae, aka black cohosh) is widely used to treat climacteric complaints as an alternative to hormone substitution. Recent trials prove efficacy and safety of the approved herbal medicinal products from extracts of pharmaceutical quality. This led to worldwide increasing sales. A higher demand for the plant material results in problems with economically motivated adulteration. Thus, reliable tools for herbal drug authentication are necessary. OBJECTIVE: To develop an economical, plain, and rapid method to distinguish between closely related American and Asian Actaea species, using securely established and resilient analytical methods coupled to a chemometric evaluation of the resulting data. METHODOLOGY: We developed and validated a RP-PDA-HPLC method including an extraction by ultra sonication to determine the genuine contents of partly hydrolysis-sensitive polyphenols in Actaea racemosa roots and rhizomes, and applied it to a large number of 203 Actaea samples consisting of seven species. RESULTS: We were able to generate reliable data with regards to the polyphenolic esters in the samples. The evaluation of this data by principle component analysis (PCA) made a discrimination between Asian Actaea species (sheng ma), one American Actaea species (Appalachian bugbane), and A. racemosa possible. CONCLUSION: The developed RP-PDA-HPLC method coupled to PCA is an excellent tool for authentication of the Actaea racemosa herbal drug, and can be a powerful addition to the TLC methods used in the dedicated pharmacopoeias, and is a promising alternative to expensive and lots of expertise requiring methods.

AB - Although lupus is, by definition, associated with genetic and immunological factors, its molecular mechanisms remain unclear. The up-to-date research findings point out that various genetic and epigenetic factors, especially gene specific and site-specific methylation, are believed to contribute to the initiation and development of systemic lupus erythematosus (SLE). This review presents and summarizes the association between abnormal DNA methylation of immune-related cells and lupus-like diseases, as well as the possible mechanisms of immune disorder caused by DNA methylation, aiming at a better understanding of the roles of aberrant DNA methylation in the initiation and development of certain forms of lupus and providing a new insight into promising therapeutic regimens in lupus-like diseases.

AB - Thermoelectric performance in the layered Zintl phase n-type Mg3+delta (Sb,Bi)2 is reported. Insertion of the excess Mg into the compounds is crucial for realizing n-type carrier transport with multivalley and isotropic character.

AB - Articular cartilage has a limited capacity to heal and, currently, no treatment exists that can restore normal hyaline cartilage. Creating tissue engineering scaffolds that more closely mimic the native extracellular matrix may be an attractive approach. Glycosaminoglycans, which are present in native cartilage tissue, provide signalling and structural cues to cells. This study evaluated the use of a glycosaminoglycan mimetic, derived from cellulose, as a potential scaffold for cartilage repair applications. Fully sulfated sodium cellulose sulfate (NaCS) was initially evaluated in soluble form as an additive to cell culture media. Human mesenchymal stem cell (MSC) chondrogenesis in pellet culture was enhanced with 0.01% NaCS added to induction media as demonstrated by significantly higher gene expression for type II collagen and aggrecan. NaCS was combined with gelatine to form fibrous scaffolds using the electrospinning technique. Scaffolds were characterized for fibre morphology, overall hydrolytic stability, protein/growth factor interaction and for supporting MSC chondrogenesis in vitro. Scaffolds immersed in phosphate buffered saline for up to 56 days had no changes in swelling and no dissolution of NaCS as compared to day 0. Increasing concentrations of the model protein lysozyme and transforming growth factor-beta3 were detected on scaffolds with increasing concentrations of NaCS (p < 0.05). MSC chondrogenesis was enhanced on the scaffold with the lowest NaCS concentration as seen with the highest collagen type II production, collagen type II immunostaining, and expression of cartilage-specific genes. These studies demonstrate the feasibility of cellulose sulfate as a scaffolding material for cartilage tissue engineering. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - Bioinspired "brick-and-mortar" alumina ceramics containing a nickel compliant phase are synthesized by coextrusion of alumina and nickel oxide.

PMID- 27690375 TI - A Novel Entry/Uncoating Assay Reveals the Presence of at Least Two Species of Viral Capsids During Synchronized HIV-1 Infection. AB - To better characterize the behavior of HIV-1 capsids we developed EURT, for Entry/Uncoating assay based on core-packaged RNA availability and Translation. EURT is an alternative to Blam-Vpr, but as reporter RNA translation relies on core opening, it can be used to study viral capsids behavior. Our study reveals the existence of two major capsid species, a dead end one in which the viral genome is readily exposed to the cytoplasm and a functional one in which such exposure requires artificial core destabilization. Although reverse transcription drives a faster loss of susceptibility of viral cores to high doses of PF74, it does not lead to higher exposure of the viral genome, implying that viral cores protect the genome irrespectively of reverse transcription. Lastly, IFNalpha drifts cores from functional to non-functional species, revealing a novel core destabilizing activity. This assay sheds new light on the behavior of viral cores inside target cells. PMID- 27690376 TI - Diversity and Variation of Bacterial Community Revealed by MiSeq Sequencing in Chinese Dark Teas. AB - Chinese dark teas (CDTs) are now among the popular tea beverages worldwide due to their unique health benefits. Because the production of CDTs involves fermentation that is characterized by the effect of microbes, microorganisms are believed to play critical roles in the determination of the chemical characteristics of CDTs. Some dominant fungi have been identified from CDTs. In contrast, little, if anything, is known about the composition of bacterial community in CDTs. This study was set to investigate the diversity and variation of bacterial community in four major types of CDTs from China. First, the composition of the bacterial community of CDTs was determined using MiSeq sequencing. From the four typical CDTs, a total of 238 genera that belong to 128 families of bacteria were detected, including most of the families of beneficial bacteria known to be associated with fermented food. While different types of CDTs had generally distinct bacterial structures, the two types of brick teas produced from adjacent regions displayed strong similarity in bacterial composition, suggesting that the producing environment and processing condition perhaps together influence bacterial succession in CDTs. The global characterization of bacterial communities in CDTs is an essential first step for us to understand their function in fermentation and their potential impact on human health. Such knowledge will be important guidance for improving the production of CDTs with higher quality and elevated health benefits. PMID- 27690377 TI - Central Nervous System Injury - A Newly Observed Bystander Effect of Radiation. AB - The unintended side effects of cancer treatment are increasing recognized. Among these is a syndrome of long-term neurocognitive dysfunction called cancer/chemotherapy related cognitive impairment. To date, all studies examining the cognitive impact of cancer treatment have emphasized chemotherapy. Radiation induced bystander effects have been described in cell culture and, to a limited extent, in rodent model systems. The purpose of this study was to examine, for the first time, the impact of non-brain directed radiation therapy on the brain in order to elucidate its potential relationship with cancer/chemotherapy related cognitive impairment. To address this objective, female BALB/c mice received either a single 16 gray fraction of ionizing radiation to the right hind limb or three doses of methotrexate, once per week for three consecutive weeks. Mice were sacrificed either 3 or 30 days post-treatment and brain injury was determined via quantification of activated astrocytes and microglia. To characterize the effects of non-brain directed radiation on brain glucose metabolism, mice were evaluated by fluorodeoxygluocose positron emission tomography. A single fraction of 16 gray radiation resulted in global decreases in brain glucose metabolism, a significant increase in the number of activated astrocytes and microglia, and increased TNF alpha expression, all of which lasted up to 30 days post-treatment. This inflammatory response following radiation therapy was statistically indistinguishable from the neuroinflammation observed following methotrexate administration. In conclusion, non-brain directed radiation was sufficient to cause significant brain bystander injury as reflected by multifocal hypometabolism and persistent neuroinflammation. These findings suggest that radiation induces significant brain bystander effects distant from the irradiated cells and tissues. These effects may contribute to the development of cognitive dysfunction in treated human cancer patients and warrant further study. PMID- 27690378 TI - IL-33-Induced Cytokine Secretion and Survival of Mouse Eosinophils Is Promoted by Autocrine GM-CSF. AB - Eosinophils are major effector cells during allergic responses and helminth infections. Recent studies further highlight eosinophils as important players in many other biological processes. Therefore it is important to understand how these cells can be modulated in terms of survival and effector function. In the present study we investigated how eosinophils respond to the alarmin IL-33. We show that IL-33 promotes eosinophil survival in a ST2- and MyD88-dependent manner. IL-33-mediated protection from apoptosis was dependent on autocrine GM CSF release. In addition, GM-CSF increased the IL-33-induced secretion of IL-4 and IL-13 from eosinophils. Unexpectedly, this effect was further enhanced by cross-linking of Siglec-F, a proposed inhibitory and apopotosis-inducing receptor on eosinophils. Co-culture experiments with eosinophils and macrophages revealed that the IL-33-induced release of IL-4 and IL-13 from eosinophils was required for differentiation of alternatively activated macrophages (AAMs). The differentiation of AAMs could be further increased in the presence of GM-CSF. These results indicate that cross-talk between Siglec-F and the receptors for IL 33, LPS and GM-CSF plays an important role for efficient secretion of IL-4 and IL 13. Deciphering the molecular details of this cross-talk could lead to the development of new therapeutic option to treat eosinophil-associated diseases. PMID- 27690379 TI - STN1 OB Fold Mutation Alters DNA Binding and Affects Selective Aspects of CST Function. AB - Mammalian CST (CTC1-STN1-TEN1) participates in multiple aspects of telomere replication and genome-wide recovery from replication stress. CST resembles Replication Protein A (RPA) in that it binds ssDNA and STN1 and TEN1 are structurally similar to RPA2 and RPA3. Conservation between CTC1 and RPA1 is less apparent. Currently the mechanism underlying CST action is largely unknown. Here we address CST mechanism by using a DNA-binding mutant, (STN1 OB-fold mutant, STN1-OBM) to examine the relationship between DNA binding and CST function. In vivo, STN1-OBM affects resolution of endogenous replication stress and telomere duplex replication but telomeric C-strand fill-in and new origin firing after exogenous replication stress are unaffected. These selective effects indicate mechanistic differences in CST action during resolution of different replication problems. In vitro binding studies show that STN1 directly engages both short and long ssDNA oligonucleotides, however STN1-OBM preferentially destabilizes binding to short substrates. The finding that STN1-OBM affects binding to only certain substrates starts to explain the in vivo separation of function observed in STN1 OBM expressing cells. CST is expected to engage DNA substrates of varied length and structure as it acts to resolve different replication problems. Since STN1 OBM will alter CST binding to only some of these substrates, the mutant should affect resolution of only a subset of replication problems, as was observed in the STN1-OBM cells. The in vitro studies also provide insight into CST binding mechanism. Like RPA, CST likely contacts DNA via multiple OB folds. However, the importance of STN1 for binding short substrates indicates differences in the architecture of CST and RPA DNA-protein complexes. Based on our results, we propose a dynamic DNA binding model that provides a general mechanism for CST action at diverse forms of replication stress. PMID- 27690380 TI - Flavonoids from Litsea japonica Inhibit AGEs Formation and Rat Lense Aldose Reductase In Vitro and Vessel Dilation in Zebrafish. AB - In our ongoing efforts to identify effective naturally sourced agents for the treating of diabetic complications, two new (1 and 2) and 11 known phenolic compounds (3-13) were isolated from an 80 % ethanol extract of Litsea japonica leaves. The structures of the new compounds were established by spectroscopic and chemical studies. These isolates (1-13) were subjected to an in vitro bioassay evaluating their inhibitory activity on advanced glycation end products formation and rat lens aldose reductase activity. Of the compounds evaluated, the flavonoids (3, 4, 6-8, 11, and 12) markedly inhibited advanced glycation end products formation, with IC50 values of 7.4-72.0 uM, compared with the positive control, aminoguanidine (IC50 = 975.9 uM). In the rat lens aldose reductase assay, consistent with the inhibition of advanced glycation end products formation, the flavonoids (3, 4, 6-8, 11, and 12) exhibited considerable inhibition of rat lens aldose reductase activity, with IC50 values of 1.1-12.5 uM. In addition, the effects of kaempferol (4) and tiliroside (7) on the dilation of hyaloid-retinal vessels induced by high glucose in larval zebrafish were investigated. Only kaempferol significantly reduced the diameters of high glucose induced hyaloid-retinal vessels, by 52.2 % at 10 uM, compared with those in the high glucose-treated control group. PMID- 27690381 TI - Association of Apolipoprotein C3 Genetic Polymorphisms with the Risk of Ischemic Stroke in the Northern Chinese Han Population. AB - The apolipoprotein C3 (APOC3) gene, which is a member of the APOA1/C3/A4/A5 gene cluster, plays a crucial role in lipid metabolism. Dyslipidemia is an important risk factor for ischemic stroke. In the present study, we performed a hospital based case-control study of 895 ischemic stroke patients and 883 control subjects to examine the effects of four APOC3 single nucleotide polymorphisms (SNPs) (rs2854116, rs2854117, rs4520 and rs5128) on the risk of ischemic stroke in a northern Chinese Han population. The SNaPshot Multiplex sequencing assay was used for SNP genotyping, and the potential association of genotype distributions and allele frequencies with ischemic stroke was analyzed statistically. Compared with the GG genotype, the CC+GC genotype of rs5128 was significantly associated with an increased risk in females (adjusted OR = 3.38, 95% CI = 1.82-6.28, P <0.01) after all of the risk factors were adjusted for with logistic regression analyses. A similar relationship was found between the rs4520 polymorphism and ischemic stroke risk in Han Chinese women. Under a recessive genetic model, the TT+TC genotypes of this variant increased ischemic stroke risk (adjusted OR = 2.05; 95% CI = 1.28-3.29; P <0.01). Haplotype analysis revealed that in males, the T-C-T-C haplotype of rs2854116-rs2854117-rs4520-rs5128 was significantly more frequent in the ischemic stroke group than in the control group (OR = 1.49, 95% CI = 1.18-1.87, P<0.01). The results of our study indicate that the APOC3 polymorphisms contribute to ischemic stroke susceptibility in females in the northern Chinese Han population. PMID- 27690382 TI - Surface Functionalization of Metal Nanoparticles by Conjugated Metal-Ligand Interfacial Bonds: Impacts on Intraparticle Charge Transfer. AB - Noble metal nanoparticles represent a unique class of functional nanomaterials with physical and chemical properties that deviate markedly from those of their atomic and bulk forms. In order to stabilize the nanoparticles and further manipulate the materials properties, surface functionalization with organic molecules has been utilized as a powerful tool. Among those, mercapto derivatives have been used extensively as the ligands of choice for nanoparticle surface functionalization by taking advantage of the strong affinity of thiol moieties to transition metal surfaces forming (polar) metal-thiolate linkages. Yet, the nanoparticle material properties are generally discussed within the context of the two structural components, the metal cores and the organic capping layers, whereas the impacts of the metal-sulfur interfacial bonds are largely ignored because of the lack of interesting chemistry. In recent years, it has been found that metal nanoparticles may also be functionalized by stable metal-carbon (or even -nitrogen) covalent bonds. Because of the formation of dpi-ppi interactions between the transition-metal nanoparticles and terminal carbon moieties, the interfacial resistance at the metal-ligand interface is markedly reduced, leading to the emergence of unprecedented optical and electronic properties. In this Account, we summarize recent progress in the studies of metal nanoparticles functionalized by conjugated metal-ligand interfacial bonds that include metal carbene (M?C) and metal-acetylide (M-C=)/metal-vinylidene (M?C?C) bonds. Such interfacial bonds are readily formed by ligand self-assembly onto nanoparticle metal cores. The resulting nanoparticles exhibit apparent intraparticle charge delocalization between the particle-bound functional moieties, leading to the emergence of optical and electronic properties that are analogous to those of their dimeric counterparts, as manifested in spectroscopic and electrochemical measurements. This is first highlighted by ferrocene-functionalized nanoparticles that exhibit nanoparticle-mediated intervalence charge transfer (IVCT) among the particle-bound ferrocenyl moieties, as manifested in electrochemical and spectroscopic measurements. Such intraparticle charge delocalization has also been observed with other functional moieties such as pyrene and anthracene, where the photoluminescence emissions are consistent with those of their dimeric derivatives. Importantly, as such electronic communication occurs via a through bond pathway, it may be readily manipulated by the valence states of the nanoparticle cores as well as specific binding of selective molecules/ions to the organic capping shells. These fundamental insights may be exploited for diverse applications, ranging from chemical sensing to (nano)electronics and fuel cell electrochemistry. Several examples are included, such as sensitive detection of nitroaromatic derivatives, metal cations, and fluoride anions by fluorophore functionalized metal nanoparticles, fabrication of nanoparticle-bridged molecular dyads by, for instance, using nanoparticles cofunctionalized with 4-ethynyl-N,N diphenyl-aniline (electron donor) and 9-vinylanthracene (electron acceptor), and enhanced electrocatalytic activity of acetylene derivatives-functionalized metal/alloy nanoparticles for oxygen reduction reaction by manipulation of the metal core electron density and hence interactions with reaction intermediates. We conclude this Account with a perspective where inspiration from conventional organometallic chemistry may be exploited for more complicated nanoparticle surface functionalization through the formation of diverse metal-nonmetal bonds. This is a unique platform for ready manipulation of nanoparticle properties and applications. PMID- 27690383 TI - Discovery of N-Alkyl Catecholamides as Selective Phosphodiesterase-4 Inhibitors with Anti-neuroinflammation Potential Exhibiting Antidepressant-like Effects at Non-emetic Doses. AB - Depression involving neuroinflammation is one of the most common disabling and life-threatening psychiatric disorders. Phosphodiesterase 4 (PDE4) inhibitors produce potent antidepressant-like and cognition-enhancing effects. However, their clinical utility is limited by their major side effect of emesis. To obtain more selective PDE4 inhibitors with antidepressant and anti-neuroinflammation potential and less emesis, we designed and synthesized a series of N-alkyl catecholamides by modifying the 4-methoxybenzyl group of our hit compound, FCPE07, with an alkyl side chain. Among these compounds, 10 compounds displayed submicromolar IC50 values in the mid- to low-nanomolar range. Moreover, 4 difluoromethoxybenzamides 10g and 10j, bearing isopropyl groups, exhibited the highest PDE4 inhibitory activities, with IC50 values in the low-nanomolar range and with higher selectivities for PDE4 (approximately 5000-fold and 2100-fold over other PDEs, respectively). Furthermore, compound 10j displayed anti neuroinflammation potential, promising antidepressant-like effects, and a zero incidence rate of emesis at 0.8 mg/kg within 180 min. PMID- 27690384 TI - Isotope Dilution UPLC-APCI-MS/MS Method for the Quantitative Measurement of Aromatic Diamines in Human Urine: Biomarkers of Diisocyanate Exposure. AB - Urinary diamines are biomarkers of diisocyanate exposure. Diisocyanates are considered as skin and respiratory sensitizers and are the most frequently reported cause of occupational asthma. Herein we report on the development and validation of an ultraperformance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the measurement of five aromatic diamines, 4,4' methylenedianiline (MDA), 2,4-toluenediamine (4TDA), 2,6-toluenediamine (6TDA), 1,5-naphthalenediamine (NDA), and p-phenylenediamine (PPDA) in human urine. The method incorporates sample preparation steps, which include a 4 h acid hydrolysis followed by high-throughput solid-phase extraction prior to chromatographic separation. Chromatographic separation was achieved using a C18 reversed phase column with gradient elution of basic mobile phases (pH 9.2). The duty cycle of the method was less than 5 min, including both the column equilibration and autosampler movement. Analytical detection was performed using positive ion atmospheric pressure chemical ionization tandem mass spectrometry (APCI-MS/MS) in scheduled multiple reaction monitoring (sMRM) mode. Excellent linearity was observed over standard calibration curve concentration ranges of 3 orders of magnitude with method detection limit ranging from 10 to 100 pg/mL. The interday and intraday reproducibility and accuracy were within +/-15%. This method is fast, accurate, and reproducible and is suitable for assessment of exposure to the most common aromatic diisocyanates within targeted groups as well as larger population studies such as the National Health and Nutrition Examination Survey (NHANES). PMID- 27690385 TI - Small-Molecule Probes Reveal Esterases with Persistent Activity in Dormant and Reactivating Mycobacterium tuberculosis. AB - Mycobacterium tuberculosis (Mtb) is the deadliest bacterial pathogen in the world. An estimated one-third of humans harbor Mtb in a dormant state. These asymptomatic, latent infections impede tuberculosis eradication due to the long term potential for reactivation. Dormant Mtb has reduced enzymatic activity, but hydrolases that remain active facilitate pathogen survival. We targeted Mtb esterases, a diverse set of enzymes in the serine hydrolase family, and studied their activities using both activity-based probes (ABPs) and fluorogenic esterase substrates. These small-molecule probes revealed functional esterases in active, dormant, and reactivating cultures. Using ABPs, we identified five esterases that remained active in dormant Mtb, including LipM (Rv2284), LipN (Rv2970c), CaeA (Rv2224c), Rv0183, and Rv1683. Three of these, CaeA, Rv0183, and Rv1683, were catalytically active in all three culture conditions. Fluorogenic probes additionally revealed LipH (Rv1399c), Culp1 (Rv1984c), and Rv3036c esterase activity in dormant and active cultures. Esterases with persistent activity are potential diagnostic biomarkers or therapeutic targets for Mtb-infected individuals with latent or active tuberculosis. PMID- 27690386 TI - Colloidal Spherical Quantum Wells with Near-Unity Photoluminescence Quantum Yield and Suppressed Blinking. AB - Thick inorganic shell endows colloidal nanocrystals (NCs) with enhanced photochemical stability and suppression of photoluminescence intermittency (also known as blinking). However, the progress of using thick-shell heterostructure NCs in applications has been limited, due to low photoluminescence quantum yield (PL QY ? 60%) at room temperature. Here, we demonstrate thick-shell NCs with CdS/CdSe/CdS seed/spherical quantum well/shell (SQW) geometry that exhibit near unity PL QY at room temperature and suppression of blinking. In SQW NCs, the lattice mismatch is diminished between the emissive CdSe layer and the surrounding CdS layers as a result of coherent strain, which suppresses the formation of misfit defects and consequently permits ~ 100% PL QY for SQW NCs with thick CdS shell (>= 5 nm). High PL QY of thick-shell SQW NCs are preserved even in concentrated dispersion and in film under thermal stress, which makes them promising candidates for applications in solid-state lightings and luminescent solar concentrators. PMID- 27690387 TI - Quantum Dots-Ligand Complex as Ratiometric Fluorescent Nanoprobe for Visual and Specific Detection of G-Quadruplex. AB - By complexing a nonionic G-quadruplex ligand with hybrid dual-emission quantum dots (QDs), a ratiometric fluorescent nanoprobe is developed for G-quadruplex detection in a sensitive and specific manner. The QDs nanohybrid comprised of a green-emission QD (gQD) and multiple red-emission QDs (rQDs) inside and outside of a silica shell, respectively, is utilized as the signal displaying unit. Only the presence of G-quadruplex can displace the ligand from QDs, breaking up the QDs-ligand complexation, and inducing the restoration of the rQDs fluorescence. Since the fluorescence of embedded gQD stays constant, variations of the dual emission intensity ratios display continuous color changes from green to bright orange, which can be clearly observed by the naked eye. Furthermore, by utilizing competitive binding of a cationic ligand versus the nonionic ligand toward G quadruplex, the nanoprobe is demonstrated to be applicable for assessing the affinity of a G-quadruplex-targeted anticancer drug candidate, exhibiting ratiometric fluorescence signals (reverse of that for G-quadruplex detection). By making use of the specificity of the ligand binding with G-quadruplex against a double helix, this nanoprobe is also demonstrated to be capable of sensitive detection of one-base mutation, exhibiting sequence-specific ratiometric fluorescence signals. By functionalizing with a nuclear localization peptide, the nanoprobe can be used for visualization of G-quadruplex in the nucleus of human cells. PMID- 27690388 TI - Bioluminescent Indicator for Highly Sensitive Analysis of Estrogenic Activity in a Cell-Based Format. AB - Estrogens regulate different physiological systems with wide ranges of concentrations. The rapid analysis of estrogens is crucially important for drug discovery and medical diagnosis, but quantitation of nanomolar estrogens in live cells persists as an important challenge. We herein describe a bioluminescent indicator used to detect low concentrations of estrogens quantitatively with a high signal-to-background ratio. The indicator comprises a ligand-binding domain of an estrogen receptor connected with its binding peptide, which is sandwiched between split fragments of a luciferase mutant. Results show that the indicator recovered its bioluminescence upon binding to 17beta-estradiol at concentrations higher than 1.0 * 10-10 M. The indicator was reactive to agonists but did not respond to antagonists. The indicator is expected to be applicable for rapid screening estrogenic compounds and inhibitors, facilitating the discovery of drug candidates in a high-throughput manner. PMID- 27690389 TI - Curcumin-Based "Enhanced SNAr" Promoted Ultrafast Fluorescent Probe for Thiophenols Detection in Aqueous Solution and in Living Cells. AB - We report herein a highly selective and sensitive turn-on fluorescent probe (compound 1) with a fast response time (less than 2 min) for thiophenol detection based on an "enhanced SNAr" reaction between thiophenols and a sulfonyl-ester moiety covalently attach to curcumin. Reaction of 1 in Hepes-MeOH (1:1, v/v, pH 7.4) in the presence of 4-methylthiophenol (MTP) resulted in a remarkable enhancement of the fluorescence. A linear response in the presence of MTP of the relative fluorescent intensity (F - F0) of 1 at 536 nm in the 0-40 MUM MTP concentration range was found. A limit of detection (LOD) for the detection of MTP of 26 nM, based on the definition by IUPAC (CDL = 3 Sb/m), was calculated. Probe 1 was applied to monitor and imaging exogenous MTP in live cells and to the detection of MTP in real water samples. PMID- 27690390 TI - Resource Sharing Controls Gene Expression Bursting. AB - Episodic gene expression, with periods of high expression separated by periods of no expression, is a pervasive biological phenomenon. This bursty pattern of expression draws from a finite reservoir of expression machinery in a highly time variant way, i.e., requiring no resources most of the time but drawing heavily on them during short intense bursts, that intimately links expression bursting and resource sharing. Yet, most recent investigations have focused on specific molecular mechanisms intrinsic to the bursty behavior of individual genes, while little is known about the interplay between resource sharing and global expression bursting behavior. Here, we confine Escherichia coli cell extract in both cell-sized microfluidic chambers and lipid-based vesicles to explore how resource sharing influences expression bursting. Interestingly, expression burst size, but not burst frequency, is highly sensitive to the size of the shared transcription and translation resource pools. The intriguing implication of these results is that expression bursts are more readily amplified than initiated, suggesting that burst formation occurs through positive feedback or cooperativity. When extrapolated to prokaryotic cells, these results suggest that large translational bursts may be correlated with large transcriptional bursts. This correlation is supported by recently reported transcription and translation bursting studies in E. coli. The results reported here demonstrate a strong intimate link between global expression burst patterns and resource sharing, and they suggest that bursting plays an important role in optimizing the use of limited, shared expression resources. PMID- 27690391 TI - Concurrent Glycogen and Lactate Imaging with FTIR Spectroscopy To Spatially Localize Metabolic Parameters of the Glial Response Following Brain Ischemia. AB - Imaging energy metabolites as markers of the energy shuttle between glia and neurons following ischemia is an ongoing challenge. Traditional microscopies in combination with histochemistry reveal glycogen accumulation within glia following ischemia, indicating an altered metabolic profile. Although semiquantitative histochemical glycogen analysis is possible, the method suffers from typical confounding factors common to histochemistry, such as variation in reagent penetration and binding. In addition, histochemical detection of glycogen does not reveal information on the metabolic fate of glycogen (i.e., lactate production). Therefore, validation of a direct semiquantitative method to simultaneously image both brain glycogen and lactate in the same tissue section would benefit this research field. In this study, we demonstrate the first application of Fourier transform infrared (FTIR) spectroscopy for simultaneous direct spectroscopic imaging of brain glycogen and lactate, in situ within ex vivo tissue sections. Serial tissue sections were analyzed with anti-glial fibrillary acidic protein (GFAP) immunohistochemistry to provide a comparison between the glycogen and lactate distribution revealed by FTIR and the glial distribution revealed by GFAP immunohistochemistry. The distribution of glycogen revealed by FTIR spectroscopic imaging has been further compared with histochemical detection of glycogen on the adjacent tissue sections. This approach was then applied to study spatiotemporal disturbances in metabolism, relative to glia and neuronal populations, following cerebral ischemia in a murine model of stroke. PMID- 27690392 TI - Chemical Isotope Labeling LC-MS for High Coverage and Quantitative Profiling of the Hydroxyl Submetabolome in Metabolomics. AB - A key step in metabolomics is to perform accurate relative quantification of the metabolomes in comparative samples with high coverage. Hydroxyl-containing metabolites are an important class of the metabolome with diverse structures and physical/chemical properties; however, many of them are difficult to detect with high sensitivity. We present a high-performance chemical isotope labeling liquid chromatography mass spectrometry (LC-MS) technique for in-depth profiling of the hydroxyl submetabolome, which involves the use of acidic liquid-liquid extraction to enrich hydroxyl metabolites into ethyl acetate from an aqueous sample. After drying and then redissolving in acetonitrile, the metabolite extract is labeled using a base-activated 12C- or 13C-dansylation reaction. A fast step-gradient LC UV method is used to determine the total concentration of labeled metabolites. On the basis of the concentration information, a 12C-labeled individual sample is mixed with an equal mole amount of a 13C-labeled pool or control for relative metabolite quantification. The 12C-/13C-labeled mixtures are individually analyzed by LC-MS, and the resultant peak pairs of labeled metabolites in MS are measured for relative quantification and metabolite identification. A standard library of 85 hydroxyl compounds containing MS, retention time, and MS/MS information was constructed for positive metabolite identification based on matches of two or all three of these parameters with those of an unknown. Using human urine as an example, we analyzed samples of 1:1 12C-/13C-labeled urine in triplicate with triplicate runs per sample and detected an average of 3759 +/- 45 peak pairs or metabolites per run and 3538 +/- 71 pairs per sample with 3093 pairs in common (n = 9). Out of the 3093 peak pairs, 2304 pairs (75%) could be positively or putatively identified based on metabolome database searches, including 20 pairs positively identified using the dansylated hydroxyl standards library. The majority of detected metabolites were those containing hydroxyl groups. This technique opens a new avenue for the detailed characterization of the hydroxyl submetabolome in metabolomics research.

AB - Two synthetic approaches to linear dasatinib-DNA conjugates via click chemistry are described. One approach involves the reaction of excess azido dasatinib derivative with 5'-(5-hexynyl) tagged DNAs and the other involves the reaction of excess alkynyl linked dasatinib with 5'-azido tagged DNA. The second approach using alkynyl derived dasatinib and 5'-azido tagged DNA yielded the corresponding dasatinib-DNA conjugates in higher yield (47% versus 10-33% for the first approach). Studies have shown these linear dasatinib-DNA conjugates derived gold nanoparticles exhibit efficacy against leukemia cancer cells with reduced toxicity toward normal cells compared to free dasatinib.

AB - The electrochemical quartz-crystal nanobalance has been used in electrochemistry research for over three decades. It provides an atomic/molecular level insight into the nature of interfacial electrochemical phenomena by measuring in situ mass changes on the nanogram scale. The sensitivity of this technique remains unknown because there have been no attempts to determine its limits of detection (LOD) or quantification (LOQ). We propose an experimental approach for determining the values of LOD and LOQ for Pt electrodes in aqueous H2SO4 solutions that employs cyclic voltammetry and frequency variation measurements. However, this methodology is also appropriate to other electrode materials and electrolytes. The LOD and LOQ values depend on the electrolyte concentration and decrease (i.e., the sensitivity increases) as the concentration decreases. Knowledge of the LOD and LOQ values determines the applicability of this technique in research on the oxidation and degradation of Pt catalysts employed in fuel cells.

AB - Theoretically designed pincer-type phosphorus compound is found to be active for the hydrogenation of carbon dioxide (CO2) with ammonia-borane. DFT, ONIOM(CCSD(T):MP2), and CCSD(T) computational results demonstrated that the reaction occurs through the phosphorus-ligand cooperative catalysis function, which provides an unprecedented protocol for metal-free CO2 conversion. The phosphorus compounds with the NNN ligand are more active than those with the ONO ligand. The conjugate and planar ligand considerably improves the efficiency of the catalyst.

PMID- 27690397 TI - CoII4, CoII7, and a Series of CoII2LnIII (LnIII = NdIII, SmIII, GdIII, TbIII, DyIII) Coordination Clusters: Search for Single Molecule Magnets. AB - We report herein the syntheses and investigation of the magnetic properties of a CoII4 compound, a series of trinuclear CoII2LnIII (LnIII = NdIII, SmIII, GdIII, TbIII, DyIII) complexes, and a CoII7 complex. The homometallic CoII4 core was obtained from the reaction of Ln(NO3)3.xH2O/Co(NO3)2.6H2O/H2vab/Et3N in a 0.5:0.5:1:2 ratio in methanol. Variation in synthetic conditions was necessary to get the desired CoII-LnIII complexes. The CoII-LnIII assembly was synthesized from Ln(NO3)3.xH2O/Co(OAc)2.4H2O/H2vab/NaOMe in a 0.4:0.5:1:1 ratio in methanol. The isostructural CoII2LnIII complexes have a core structure with the general formula [Co2Ln(Hvab)4(NO3)](NO3)2.MeOH.H2O, (where H2vab = 2-[(2-hydroxymethyl phenylimino)-methyl]-6-methoxy-phenol) with simultaneous crystallization of CoII7 complex in each reaction. The magnetic investigation of these complexes reveals that both homometallic complexes and four CoII-LnIII complexes (except CoII NdIII) display behavior characteristic of single molecule magnets. PMID- 27690398 TI - Manifestation of Anomalous Weak Space-Charge-Density Acentricity for a Tl4HgBr6 Single Crystal. AB - Density functional theory (DFT) calculations within the concept of the MBJ+U+SO (modified Becke-Johnson potential + U + spin orbit) approach were performed for a Tl4HgBr6 single crystal for the first time assuming weak noncentrosymmetry (space group P4nc). Excellent agreement was achieved between the calculated and experimental band-gap-energy magnitudes as well as the density of electronic states measured by the X-ray photoelectron spectroscopy method. It is a very principal result because usually the DFT calculations underestimate the energy gap values. In the present study, we carry out calculations of the optical properties (absorption coefficient, real and imaginary parts of the dielectric function, electron energy-loss spectrum, refractive index, extinction coefficient, and optical reflectivity dispersions). It has been established that the principal origin of the observed weak acentricity is determined by delocalized band states at the top of the valence band originating from the p states of the Br atoms. PMID- 27690399 TI - Controls on Nitrous Oxide Emissions from the Hyporheic Zones of Streams. AB - The magnitude and mechanisms of nitrous oxide (N2O) release from rivers and streams are actively debated. The complex interactions of hydrodynamic and biogeochemical controls on emissions of this important greenhouse gas preclude prediction of when and where N2O emissions will be significant. We present observations from column and large-scale flume experiments supporting an integrative model of N2O emissions from stream sediments. Our results show a distinct, replicable, pattern of nitrous oxide generation and consumption dictated by subsurface (hyporheic) residence times and biological nitrogen reduction rates. Within this model, N2O emission from stream sediments requires subsurface residence times (and microbially mediated reduction rates) be sufficiently long (and fast reacting) to produce N2O by nitrate reduction but also sufficiently short (or slow reacting) to limit N2O conversion to dinitrogen gas. Most subsurface exchange will not result in N2O emissions; only specific, intermediate, residence times (reaction rates) will both produce and release N2O to the stream. We also confirm previous observations that elevated nitrate and declining organic carbon reactivity increase N2O production, highlighting the importance of associated reaction rates in controlling N2O accumulation. Combined, these observations help constrain when N2O release will occur, providing a predictive link between stream geomorphology, hydrodynamics, and N2O emissions. PMID- 27690400 TI - Environmental Origins of Methylmercury Accumulated in Subarctic Estuarine Fish Indicated by Mercury Stable Isotopes. AB - Methylmercury (MeHg) exposure can cause adverse reproductive and neurodevelopmental health effects. Estuarine fish may be exposed to MeHg produced in rivers and their watersheds, benthic sediment, and the marine water column, but the relative importance of each source is poorly understood. We measured stable isotopes of mercury (delta202Hg, Delta199Hg, and Delta201Hg), carbon (delta13C), and nitrogen (delta15N) in fish with contrasting habitats from a large subarctic coastal ecosystem to better understand MeHg exposure sources. We identify two distinct food chains exposed to predominantly freshwater and marine MeHg sources but do not find evidence for a benthic marine MeHg signature. This is consistent with our previous research showing benthic sediment is a net sink for MeHg in the estuary. Marine fish display lower and less variable Delta199Hg values (0.780/00 to 1.770/00) than freshwater fish (0.720/00 to 3.140/00) and higher delta202Hg values (marine: 0.10/00 to 0.570/00; freshwater: -0.760/00 to 0.150/00). We observe a shift in the Hg isotopic composition of juvenile and adult rainbow smelt (Osmerus mordax) when they transition between the freshwater and marine environment as their dominant foraging territory. The Hg isotopic composition of Atlantic salmon (Salmo salar) indicates they receive most of their MeHg from the marine environment despite a similar or longer duration spent in freshwater regions. We conclude that stable Hg isotopes effectively track fish MeHg exposure sources across different ontogenic stages. PMID- 27690401 TI - Light-Induced Activation of a Molybdenum Oxotransferase Model within a Ru(II) Mo(VI) Dyad. AB - Nature uses molybdenum-containing enzymes to catalyze oxygen atom transfer (OAT) from water to organic substrates. In these enzymes, the two electrons that are released during the reaction are rapidly removed, one at a time, by spatially separated electron transfer units. Inspired by this design, a Ru(II)-Mo(VI) dyad was synthesized and characterized, with the aim of accelerating the rate determining step in the cis-dioxo molybdenum-catalyzed OAT cycle, the transfer of an oxo ligand to triphenyl phosphine, via a photo-oxidation process. The dyad consists of a photoactive bis(bipyridyl)-phenanthroline ruthenium moiety that is covalently linked to a bioinspired cis-dioxo molybdenum thiosemicarbazone complex. The quantum yield and luminescence lifetimes of the dyad [Ru(bpy)2(L2)MoO2(solv)]2+ were determined. The major component of the luminescence decay in MeCN solution (tau = 1149 +/- 2 ns, 67%) corresponds closely to the lifetime of excited [Ru(bpy)2(phen-NH2)]2+, while the minor component (tau = 320 +/- 1 ns, 31%) matches that of [Ru(bpy)2(H2-L2)]2+. In addition, the (spectro)electrochemical properties of the system were investigated. Catalytic tests showed that the dyad-catalyzed OAT from dimethyl sulfoxide to triphenyl phosphine proceeds significantly faster upon irradiation with visible light than in the dark. Methylviologen acts as a mediator in the photoredox cycle, but it is regenerated and hence only required in stoichiometric amounts with respect to the catalyst rather than sacrificial amounts. It is proposed that oxidative quenching of the photoexcited Ru unit, followed by intramolecular electron transfer, leads to the production of a reactive one electron oxidized catalyst, which is not accessible by electrochemical methods. A significant, but less pronounced, rate enhancement was observed when an analogous bimolecular system was tested, indicating that intramolecular electron transfer between the photosensitizer and the catalytic center is more efficient than intermolecular electron transfer between the separate components. PMID- 27690402 TI - Polymorphism in Strontium Tungstate SrWO4 under Quasi-Hydrostatic Compression. AB - The structural and vibrational properties of SrWO4 have been studied experimentally up to 27 and 46 GPa, respectively, by angle-dispersive synchrotron X-ray diffraction and Raman spectroscopy measurements as well as using ab initio calculations. The existence of four polymorphs upon quasi-hydrostatic compression is reported. The three phase transitions were found at 11.5, 19.0, and 39.5 GPa. The ambient-pressure SrWO4 tetragonal scheelite-type structure (S.G. I41/a) undergoes a transition to a monoclinic fergusonite-type structure (S.G. I2/a) at 11.5 GPa with a 1.5% volume decrease. Subsequently, at 19.0 GPa, another structural transformation takes place. Our calculations indicate two possible post-fergusonite phases, one monoclinic and the other orthorhombic. In the diffraction experiments, we observed the theoretically predicted monoclinic LaTaO4-type phase coexisting with the fergusonite-type phase up to 27 GPa. The coexistence of the two phases and the large volume collapse at the transition confirm a kinetic hindrance typical of first-order phase transitions. Significant changes in Raman spectra suggest a third pressure-induced transition at 39.5 GPa. The conclusions extracted from the experiments are complemented and supported by ab initio calculations. Our data provides insight into the structural mechanism of the first transition, with the formation of two additional W-O contacts. The fergusonite-type phase can be therefore considered as a structural bridge between the scheelite structure, composed of [WO4] tetrahedra, and the new higher pressure phases, which contain [WO6] octahedra. All the observed phases are compatible with the high-pressure structural systematics predicted for ABO4 compounds using crystal-chemistry arguments such as the diagram proposed by Bastide. PMID- 27690403 TI - First Measurements of the Nitrogen Isotopic Composition of NOx from Biomass Burning. AB - The nitrogen isotopic composition (delta15N) of NOx (NO + NO2) was measured during the fourth Fire Lab at Missoula Experiment (FLAME-4). The delta15N-NOx produced by burning a variety of biomass types ranged from -7 to +120/00 (vs air N2). In the laboratory experiments, two types of emissions were sampled: "stack" fires where the emissions were measured within a few seconds of production from the fire and "chamber" fires where the emissions were held in a room for 1-2 h and sampled continuously. For both types of emissions sampled, the primary control on delta15N-NOx is the delta15N of the biomass burned (delta15N-biomass), although differences were found for delta15N-NOx between the two types of fires. For the stack emissions, delta15N-NOx = 0.41 * delta15N-biomass +1.0 (R2 = 0.83, p-value <0.001) and for the chamber fires, delta15N-NOx = 0.98 * delta15N-biomass +1.7 (R2 = 0.94, p-value <0.001). While a large range of delta15N-NOx values were observed, the strong relationship between delta15N-NOx and delta15N-biomass suggests that in any given environment, the delta15N-NOx can be predicted. PMID- 27690404 TI - Gas-Phase Mechanisms of the Reactions of Reduced Organic Nitrogen Compounds with OH Radicals. AB - Research on the fate of reduced organic nitrogen compounds in the atmosphere has gained momentum since the identification of their crucial role in particle nucleation and the scale up of carbon capture and storage technology which employs amine-based solvents. Reduced organic nitrogen compounds have strikingly different lifetimes against OH radicals, from hours for amines to days for amides to years for isocyanates, highlighting unique functional group reactivity. In this work, we use ab initio methods to investigate the gas-phase mechanisms governing the reactions of amines, amides, isocyanates and carbamates with OH radicals. We determine that N-H abstraction is only a viable mechanistic pathway for amines and we identify a reactive pathway in amides, the formyl C-H abstraction, not currently considered in structure-activity relationship (SAR) models. We then use our acquired mechanistic knowledge and tabulated literature experimental rate coefficients to calculate SAR factors for reduced organic nitrogen compounds. These proposed SAR factors are an improvement over existing SAR models because they predict the experimental rate coefficients of amines, amides, isocyanates, isothiocyanates, carbamates and thiocarbamates with OH radicals within a factor of 2, but more importantly because they are based on a sound fundamental mechanistic understanding of their reactivity. PMID- 27690405 TI - Defining a physical basis for diversity in protein self-assemblies using a minimal model. AB - Self-assembly of proteins into ordered, fibrillar structures is a commonly observed theme in biology. It has been observed that diverse set of proteins (e.g alpha-synuclein, insulin, TATA-box binding protein, Sup35, p53), independent of their sequence, native structure, or function could self-assemble into highly ordered structures known as amyloids. What are the crucial features underlying amyloidogenesis that make it so generic? Using coarse-grained simulations of peptide self-assembly, we argue that variation in two physical parameters- bending-stiffness of the polypeptide and strength of inter-molecular interactions can give rise to many of the structural features typically associated with amyloid self-assembly. We show that the interplay between these two factors gives rise to a rich phase diagram displaying high diversity in aggregated states. For certain parameters, we find a bimodal distribution for the order parameter implying the co-existence of ordered and disordered aggregates. Our findings may explain the experimentally observed variability including the 'off-pathway' aggregated structures. Further, we demonstrate that sequence-dependence and protein-specific signatures could be mapped to our coarse-grained framework to study self-assembly behavior of realistic systems such as the STVIIE peptide and Abeta42. The work also provides certain guiding principles which could be used to design novel peptides with desired self-assembly properties, by tuning a few physical parameters. PMID- 27690406 TI - Why is the Ir(III)-Mediated Amido Transfer Much Faster Than the Rh(III)-Mediated Reaction? - A Combined Experimental and Computational Study. AB - The mechanism of the Ir(III) and Rh(III)-mediated C-N coupling reaction, which is the key step of catalytic C-H amidation, was investigated in an integrated experimental and computational study. Novel amidating agents containing a 1,4,2 dioxazole moiety allowed for designing a stoichiometric version of the catalytic C-N coupling reaction and giving access to reaction intermediates that reveal details about each step of the reaction. Both DFT and kinetic studies strongly point to a mechanism where the M(III) complex engages the amidating agent via oxidative coupling to form a M(V)-imido intermediate, which then undergoes migratory insertion to afford the final C-N coupled product. For the first time, the stoichiometric versions of the Ir and Rh-mediated amidation reaction were compared systematically to each other. Iridium reacts much faster than rhodium (~ 1100 times at 6.7 degrees C) with the oxidative coupling being so fast that the activation of the initial Ir(III)-complex becomes rate-limiting. In the case of Rh, the Rh-imido formation step is rate-limiting. These qualitative difference stems from a unique bonding feature of the dioxazole moiety and the relativistic contraction of the Ir(V), which affords much more favorable energetics for the reaction. For the first time, a full molecular orbital analysis is presented to rationalize and explain the electronic features that govern this behavior. PMID- 27690407 TI - Colloidal Single-Layer Quantum Dots with Lateral Confinement Effects on 2D Exciton. AB - Controlled lateral quantum confinement in single-layer transition-metal chalcogenides (TMCs) can potentially combine the unique properties of two dimensional (2D) exciton with the size-tunability of exciton energy, creating the single-layer quantum dots (SQDs) of 2D TMC materials. However, exploring such opportunities has been challenging due to the limited ability to produce well defined SQDs with sufficiently high quality and size control, in conjunction with the commonly observed inconsistency in the optical properties. Here, we report an effective method to synthesize high-quality and size-controlled SQDs of WSe2 via multilayer quantum dots (MQDs) precursors, which enables grasping a clear picture of the role of lateral confinement on the optical properties of the 2D exciton. From the single-particle optical spectra and polarization anisotropy of WSe2 SQDs of varying sizes in addition to their ensemble data, we reveal how the properties of 2D exciton in single-layer TMCs evolve with increasing lateral quantum confinement.

AB - Stimulation of anaerobic digestion by essential trace metals is beneficial from a practical point of view to enhance the biodegradability and degradation rate of wastes. Hence, a quick method to determine which metal species, and at what concentration, can optimize anaerobic digestion is of great interest to both researchers and operators. In this present study, we investigated the effect of nickel(II), cobalt(II), and their mixture, on the anaerobic digestion of synthetic municipal wastewater. Using a volumetric method, that is, measuring methane production over time, revealed that anaerobic digestion was stimulated by the addition of 5 mg L-1 nickel(II), and cobalt(II), and their mixture in day(s). However, using a novel resazurin reduction assay, and based on its change in rate over time, we evaluated both inhibition at 250 mg L-1 nickel(II) and cobalt(II), and also the stimulatory effect of 5 mg L-1 nickel(II), and cobalt(II), and their mixture, in just 6 h. By investigating the dynamic distribution of these metals in the liquid phase of the anaerobic system and kinetics of resazurin reduction by nickel spiked anaerobic sludge, the concentration of nickel(II) on anaerobic digestion performance was profiled. Three critical concentrations were determined; stimulation starting (around 1 mg L-1), stimulation ending (around 100 mg L-1) and stimulation maximizing (around 10 mg L-1). Hence, we propose that the resazurin reduction assay is a novel and quick protocol for studying the stimulation of anaerobic bioprocesses by bioavailable essential trace metals.

AB - Photoelectrochemical CO2 reduction activity of a hybrid photocathode, based on a Ru(II)-Re(I) supramolecular metal complex photocatalyst immobilized on a NiO electrode (NiO-RuRe) was confirmed in an aqueous electrolyte solution. Under half reaction conditions, the NiO-RuRe photocathode generated CO with high selectivity, and its turnover number for CO formation reached 32 based on the amount of immobilized RuRe. A photoelectrochemical cell comprising a NiO-RuRe photocathode and a CoOx/TaON photoanode showed activity for visible-light-driven CO2 reduction using water as a reductant to generate CO and O2, with the assistance of an external electrical (0.3 V) and chemical bias (0.10 V) produced by a pH difference. This is the first example of a molecular and semiconductor photocatalyst hybrid-constructed photoelectrochemical cell for visibl-light driven CO2 reduction using water as a reductant. PMID- 27690410 TI - Sub-stoichiometric Molybdenum Sulfide Phases with Catalytically Active Basal Planes. AB - Molybdenum sulfide (MoS2) is widely recognized for its catalytic activities where the edges of the crystals turn over reactions. Generating sulfur defects on the basal plane of MoS2 can improve its catalytic activity, but generally there is a lack of model system for understanding metal-centered catalysis on the basal planes. Here, we synthesized a new phase of sub-stoichiometric molybdenum sulfide (s-MoSx) on sulfur-enriched copper substrate. The basal plane of s-MoSx contains chemically reactive Mo-rich sites that can undergo dynamic dissociative adsorption/desorption processes with molecular hydrogen, thus demonstrating its usefulness for hydrogen-transfer catalysis. In addition, scanning tunneling microscopy was used to monitor surface-directed Ullmann coupling of 2,8-dibromo dibenzothiophene (DBDBT) molecules on s-MoSx nanosheets, where the four-fold symmetric surface sites on s-MoSx direct C-C coupling to form cyclic tetramers with high selectivity.

AB - Clusters have been identified as important growth intermediates during III-V quantum dot (QD) formation. Here we report a one-solvent protocol that integrates synthesis, purification and mass characterization of indium phosphide quantum dot growth mixtures. The use of matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS) successfully tracks the evolution of clusters and the formation of quantum dots throughout the synthesis. Similar clusters are observed during the formation of large particles, suggesting that these clusters serve as a reservoir for quantum dot formation. Combining MALDI and NMR techniques further enables us to extract extinction coefficients and construct sizing curves for cluster-free indium phosphide QDs. The use of MALDI MS opens new opportunities for characterization and mechanistic studies of small-sized air-sensitive clusters or QDs.

AB - Nature synthesizes many strained natural products that have diverse biological activities. Uncovering these biosynthetic pathways may lead to biomimetic strategies for organic synthesis of such compounds. In this work, we elucidated the concise biosynthetic pathway of herquline A, a highly strained and reduced fungal piperazine alkaloid. The pathway builds on a nonribosomal peptide synthetase de-rived di-tyrosine piperazine intermediate. Following enzymatic reduction of the P450-crosslinked di-cyclohexadienone, N-methylation of the piperazine serves as a trigger that leads to a cascade of stereoselective and nonenzymatic transformations. Computational analysis of key steps in the pathway rationalizes the observed reactivities.

AB - Crystalline and amorphous molybdenum sulfide (Mo-S) catalysts are leaders as earth abundant materials for electrocatalytic hydrogen production. The development of a molecular motif inspired by the Mo-S catalytic materials and their active sites is of interest, as molecular species possess a great degree of tunable electronic prop-erties. Furthermore, these molecular mimics may be important for providing mechanistic insights towards the hydrogen evolution reaction (HER) with Mo-S electrocatalysts. Herein is presented two water soluble Mo-S complexes based around the [MoO(S2)2L2]1- motif. We present 1H-NMR spectra that reveal (NEt4)[MoO(S2)2picolinate] (Mo-pic) is stable in a d6-DMSO solution after heating at 100 degrees C, in air, revealing unprecedented thermal and aerobic stability of the homogenous electrocatalyst. Both Mo-pic and (NEt4)[MoO(S2)2pyrimidine-2-carboxylate] (Mo-pym) are shown to be homogenous electrocatalysts for the HER. The TOF of 27-34 s-1 and 42-48 s-1 for Mo-pic and Mo-pym and onset potentials of 240 mV and 175 mV for Mo-pic and Mo-pym respectively reveal these complexes as promising electrocatalysts for the HER.

AB - Cranberry is reported to have health benefits including prevention of urinary tract infections and other chronic diseases, due to the high content of polyphenols including flavonols and flavan-3-ols. The aim of this study was to determine the clearance of flavonol glycosides and flavan-3-ols and/or their metabolites in human urine. Ten healthy women volunteers ingested 240 ml cranberry juice containing flavonol glycosides. Urine samples were collected at 0, 90, 225 and 360 minutes post-ingestion. While flavan-3-ols were not detected, five flavonol glycosides common in cranberry were identified. Quercetin-3 galactoside, the most abundant cranberry flavonol, exhibited highest peak urine concentration (Cmax) of 1315 pg/mg creatinine, followed by quercetin-3 rhamnoside, quercetin-3-arabinoside, myricetin-3-arabinoside and myricetin-3 galactoside. Quercetin-3-arabinoside showed delayed clearance, Cmax at 237 min (Tmax), relative to other flavonols (90-151 min). Both aglycone and conjugated sugar moiety structure mediates the flavonol's bioavailability. Inter-individual variation for bioavailability and clearance is also apparent. Metabolites, e.g. glucoronides, were not detected.

AB - Effect of NaCl, KCl, CaCl2, NaHCO3, and NH4HCO3 on the formation of glucosone, 1 deoxyglucosone, 3-deoxyglucosone, glyoxal, methylglyoxal, diacetyl, 5 hydroxymethyl-2-furfural, 2-furfural and browning were investigated in cookies. Presence of 1.5% NaCl, 1% KCl, and 1% CaCl2 on flour basis had no effect on alpha dicarbonyl compounds, except 1-deoxyglucosone increased in the presence of KCl and CaCl2. The increase in 5-hydroxymethyl-2-furfural formation in the presence of NaCl, KCl, and CaCl2 did not relate to 3-deoxyglucosone formation and pH changes. NaCl, KCl, and CaCl2 increased browning in cookies. Model reaction systems indicated that NaCl, KCl, and CaCl2 enhance browning by increasing furfurals in caramelization. NaCl, KCl, and CaCl2 decreased browning intensity in heated glucose-glycine system. Usage of CaCl2 in cookies may considerably increase furfurals but not alpha-dicarbonyl compounds. Sodium reduction can be obtained by replacement with potassium without sacrificing the desired consequences of caramelization in sugar rich bakeries.

AB - Understanding nitrogen (N) status in the leaves of Chinese cabbage (Brassica rapa Chinensis) is of significance to both vegetable growth and quality control. Fourier transform infrared photoacoustic spectroscopy was used to perform rapid qualification of N distribution in leaf, a partial least squares algorithm was used to develop a model for prediction of N content, and N distribution in individual leaves was mapped based on interpolation analysis, which was found to be variable. A reasonable N input level (12 mmol L-1 N) showed the largest variance of N content, benefiting N redistribution and use efficiency, but variance decreased at old stage. Moreover, the pattern of N distribution within a leaf was irregular even among the replications performed for each treatment, and sunlight was found to be the dominant factor because of leaves receiving variable light intensities.

AB - The specific contribution of different stearoyl-ACP desaturase (SAD) genes to the oleic acid content in olive (Olea europaea) fruit has been studied. Towards that end, we isolated three distinct cDNA clones encoding three SAD isoforms from olive (cv. Picual), as revealed by sequence analysis. The expression levels of olive SAD genes were determined in different tissues from Picual and Arbequina cultivars, including developing mesocarp and seed, together with the unsaturated fatty acid content. Lipid and gene expression analysis indicate that OeSAD2 seems to be the main gene contributing to the oleic acid content of the olive fruit and, therefore, of the virgin olive oil. This conclusion was confirmed when the study was extended to Hojiblanca, Picudo and Manzanilla cultivars. Furthermore, our data indicate that the olive microsomal oleate desaturase gene OeFAD2-2, but not OeSAD2, is responsible for the linoleic acid content in the virgin olive oil.

AB - Tanshinones are a group of active diterpenes with pharmacological properties, are widely used in treatment of cardiovascular diseases. Jasmonate (JA) acts as an elicitor to enhance tanshinone biosynthesis in Salvia miltiorrhiza. However, due to high labor costs and undesirable chemical characteristics, the use of JA elicitation is still in the experimental stage. In our experiments, overexpression of Lycopersicon esculentum (tomato) Prosystemin (LePS) in transgenic plants of S. miltiorrhiza increased their JA concentrations, significantly enhanced productions of tanshinone, as well as activated the expression of key genes in the tanshinone biosynthesis pathway. Meanwhile, the relative levels of metabolites related to defense such as sterols, terpenes, and phenolic acids were also increased in our OEP lines. In addition, when the larvae of cotton bollworms (Heliothis armigera) were fed with leaves from transgenic lines, their mortality rates rose by nearly four-fold when compared with larvae exposed to leaves from the non-transformed wild type. Our study provides a new strategy for genetic engineering by which tanshinone production and pest resistance can be improved in S. miltiorrhiza. This is accomplished by simulating the wounding signal that increases endogenous levels of JA.

The behavioral studies showed that caffeinated coffee decreased immobility time in both the tail suspension test (caffeinated coffee 56.60 +/- 9.17; p < 0.0001) and the forced swimming test (caffeinated coffee 28.80 +/- 5.93; p < 0.0001), suggesting antidepressant-like activity. The effects of caffeinated coffee on the inflammatory biomarkers associated with depression supported the results observed in the behavioral studies. Statistically significant decreases in indoleamine 2,3-dioxygenase activity (p < 0.001) and the neopterin/biopterin ratio (p < 0.001) were observed in animals pretreated with caffeinated coffee 24 h post-lipopolysaccharide exposure in comparison to the lipopolysaccharide control group. In conclusion, this study has provided evidence to suggest that caffeinated coffee has antidepressant-like activities; however, further studies are required to fully investigate these effects.

AB - Linking lignin model compounds to carrier proteins is required in order either to raise antibodies to them or to structurally screen antibodies raised against lignins or models. We describe a flexible method to link phenolic compounds of interest to cationic bovine serum albumin (cBSA) without interfering with their important structural features. With the guaiacylglycerol-beta-guaiacyl ether dimer, for example, the linking was accomplished in 89% yield with the number of dimers per carrier protein being as high as 50; NMR experiments on a 15N- and 13C labeled conjugation product indicated that 13 dimers were added to the native lysine residues and the remainder (~37) to the amine moieties on the ethylenediamine linkers added to BSA; ~32% of the available primary amine groups on cBSA were therefore conjugated to the hapten. This loading is suitable for attempting to raise new antibodies to plant lignins and for screening.

AB - Aminoglycosides (AGs) constitute a major family of potent and broad-spectrum antibiotics disturbing protein synthesis through binding to the A site of 16S rRNA. Decades of widespread clinical use of AGs strongly reduced their clinical efficacy through the selection of resistant bacteria. Recently, conjugation of lipophilic groups to AGs generated a novel class of potent antibacterial amphiphilic aminoglycosides (AAGs) with significant improved activities against various sensitive and resistant bacterial strains. We have identified amphiphilic 3',6-dialkyl derivatives of the small aminoglycoside neamine as broad spectrum antibacterial agents targeting bacterial membranes. Here, we report on the synthesis and the activity against sensitive and resistant Gram-negative and/or Gram-positive bacteria of new amphiphilic 3',4'-dialkyl neamine derivatives and of their smaller analogues in the 6-aminoglucosamine (neosamine) series prepared from N-acetylglucosamine.

AB - The adsorption coefficient of racemic metalaxyl onto an agriculture soil was small and non-enantioselective. Biotransformation was the predominant pathway for the elimination of R-metalaxyl, while abiotic and biotransformation made a comparable contribution to the degradation of S-metalaxyl. Metalaxyl acid was the main transformation intermediate. The enantiomer fraction of metalaxyl decreased with an increase in its initial spike concentration or the presence of the co constituents in metalaxyl commercial products. Under simulated solar irradiation, the presence of TiO2 promoted the overall transformation kinetics through enhanced biotransformation and extra photo-induced chemical reactions. The promotion was enantioselective and thereafter changed the enantiomer fraction. The results obtained in this study showed that some achiral parameters, although they have no direct impact on enantioselective reactions with enantiomers, can significantly affect the enantioselective transformation of racemic metalaxyl. Thus, our results indicate that the contribution of chemical interactions on the enantioselective transformation of chiral pesticides may be underestimated. PMID- 27690424 TI - Elucidation of Thermally Induced Changes in Key Odorants of White Mustard Seeds (Sinapis alba L.) and Rapeseeds (Brassica napus L.) Using Molecular Sensory Science. AB - Heat-processing of Brassica seeds led to the formation of a characteristic pleasant popcorn-like and coffee-like aroma impression compared to the mainly pea like aroma of the corresponding raw seeds. To analyze this phenomenon on a molecular basis, raw and roasted white mustard seeds and rapeseeds were analyzed using the sensomics approach. Application of comparative aroma extract dilution analysis (cAEDA) and identification experiments to raw and roasted (140 degrees C, 30 min) mustard seeds revealed 36 odorants (all identified for the first time) and 47 odorants (41 newly identified), respectively. Twenty-seven odorants in raw and 43 odorants in roasted (140 degrees C, 60 min) rapeseeds were found, which were all described for the first time. Among the set of volatiles, 2-isopropyl-3 methoxypyrazine (earthy, pea-like) and 4-ethenyl-2-methoxyphenol (clove-like, smoky) showed high FD factors in both raw seeds. 4-Hydroxy-2,5-dimethylfuran 3(2H)-one (caramel-like), 2,3-diethyl-5-methylpyrazine (earthy), dimethyl trisulfide (cabbage-like), and 2-acetyl-1-pyrroline (popcorn-like) were present at high flavor dilution (FD) factors in both roasted Brassica seeds. Odorants, differing in cAEDA or showing high FD factors in at least one of the seeds, were quantitated by stable isotope dilution analysis (SIDA), followed by the calculation of odor activity values (OAVs) using odor thresholds determined in refined sunflower oil. Eighteen aroma compounds in raw and 28 in roasted mustard seeds as well as 14 in raw and 25 in roasted rapeseeds revealed OAVs >=1. All four aroma recombinates, prepared by mixing the odorants showing OAVs >=1 in their naturally occurring concentrations, showed a very good similarity with the original seeds and, thus, proved the successful characterization of the respective key odorants. PMID- 27690425 TI - Antioxidant Properties of Heterocyclic Intermediates of the Maillard Reaction and Structural Related Compounds. AB - It is well established that a wide range of reductones is formed in the course of the Maillard reaction and that these substances contribute to the oxidative stability of food. The aim of this study was to analyze twelve important heterocyclic intermediates with and without reductone structure as well as structural related substances under equal conditions to compare their antioxidant properties in detail. For this purpose, five methods were selected including photometrical methods like the trolox equivalent antioxidant capacity assay and an electron paramagnetic resonance spectroscopic method. Reductones with furan-3 one structure and 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one were reducing in all assays while isomaltol and maltol did not react in assays based on the reduction of metal ions because of their complexing abilities. The introduction of protecting groups to the free hydroxyl functions of selected reductones could nearly eliminate their reducing abilities. In addition, the oxidation products of the different reductive heterocycles were compared after treatment with iodine. Mainly short-chained organic acids like lactic, glycolic and glyceric acid are formed as result of the degradation which indicate 1,3-dicarbonyl cleavage reactions of corresponding tricarbonyl compounds as intermediates of the oxidation.

AB - The performance of FeHBED in preventing Fe deficiency chlorosis in soybean (Glycine max (L.) Merr.) in comparison to FeEDDHA and FeEDDHMA was studied, as well as the importance of the ortho-ortho and ortho-para/rest isomers in defining the performance. To this end, chlorophyll production (SPAD), plant dry matter yield, and the mass fractions of important mineral elements in the plant were quantified in a greenhouse pot experiment. All three Fe chelates increased SPAD index and dry matter yield compared to the control. The effect of FeHBED on chlorophyll production was visible over a longer time span than that of FeEDDHA and FeEDDHMA. Additionally, FeHBED did not suppress Mn uptake as much as the other Fe chelates. Compared to the other Fe chelates, total Fe content in the young leaves was lower in the FeHBED treatment; however, total Fe content was not directly related to chlorophyll production and biomass yield. For each chelate, the ortho-ortho isomer was found to be more effective than the other isomers evaluated.

AB - Late sodium current (late INa) is enhanced during ischemia by reactive oxygen species (ROS) modifying the Nav 1.5 channel, resulting in incomplete inactivation. Compound 4 (GS-6615, eleclazine) a novel, potent, and selective inhibitor of late INa, is currently in clinical development for treatment of long QT-3 syndrome (LQT-3), hypertrophic cardiomyopathy (HCM), and ventricular tachycardia-ventricular fibrillation (VT-VF). We will describe structure-activity relationship (SAR) leading to the discovery of 4 that is vastly improved from the first generation late INa inhibitor 1 (ranolazine). Compound 4 was 42 times more potent than 1 in reducing ischemic burden in vivo (S-T segment elevation, 15 min left anteriorior descending, LAD, occlusion in rabbits) with EC50 values of 190 and 8000 nM, respectively. Compound 4 represents a new class of potent late INa inhibitors that will be useful in delineating the role of inhibitors of this current in the treatment of patients. PMID- 27690428 TI - 4-(((4-Iodophenyl)methyl)-4H-1,2,4-triazol-4-ylamino)-benzonitrile: A Potential Imaging Agent for Aromatase. AB - Aromatase (CYP19) is a rate-limiting enzyme that catalyzes the biosynthesis of estrogens. Imaging agents based on aromatase inhibitors (AIs) have been developed for a PET/SPECT study. A series of compounds was synthesized based on YM511, which has previously been used for breast cancer treatment. Two examples of these derivatives, 4-(((4-iodophenyl)methyl)-4H-1,2,4-triazol-4-yl-amino)-benzonitrile (5) and 4-((1H-imidazol-1-yl)(4-iodobenzyl)amino)benzonitrile (11), displayed potent binding affinities to human aromatase (IC50 = 0.17 and 0.04 nM, respectively). Biodistribution and autoradiographic studies revealed that [125I]5 and [125I]11 were highly accumulated in the stomach (16.21 and 10.88% dose/g, respectively) and ovaries (8.56 and 3.32% dose/g, respectively) of female rats. Log P of [125I]5 was 2.49, meaning good brain penetration. Autoradiograms of brain sections showed a high uptake in the bed nucleus of the stria terminalis and amygdala. These results suggest that [125I]5 and [125I]11 are potent probes for aromatase imaging in both the brain and peripheral organs.

AB - Indoleamine 2,3-dioxygenase 1 (IDO1) is an attractive target for anticancer therapy. Herein, we report a virtual screening study which led to the identification of compound 5 as a new IDO1 inhibitor. In order to improve the biological activity of the identified hit, arylthioindoles 6-30 were synthesized and tested. Among these, derivative 21 exhibited an IC50 value of 7 MUM, being the most active compound of the series. Furthermore, compounds 5 and 21 induced a dose-dependent growth inhibition in IDO1 expressing cancer cell lines HTC116 and HT29. Three-dimensional quantitative structure-activity relationship studies were carried out in order to rationalize obtained results and suggest new chemical modifications. PMID- 27690430 TI - Side Chain Cyclized Aromatic Amino Acids: Great Tools as Local Constraints in Peptide and Peptidomimetic Design. AB - Constraining the conformation of flexible peptides is a proven strategy to increase potency, selectivity, and metabolic stability. The focus has mostly been on constraining the backbone dihedral angles; however, the correct orientation of the amino acid side chains (chi-space) that constitute the peptide pharmacophore is equally important. Control of chi-space utilizes conformationally constrained amino acids that favor, disfavor, or exclude the gauche (-), the gauche (+), or the trans conformation. In this review we focus on cyclic aromatic amino acids in which the side chain is connected to the peptide backbone to provide control of chi1- and chi2-space. The manifold applications for cyclized analogues of the aromatic amino acids Phe, Tyr, Trp, and His within peptide medicinal chemistry are showcased herein with examples of enzyme inhibitors and ligands for G protein coupled receptors. PMID- 27690431 TI - Sydnone Cycloaddition Route to Pyrazole-Based Analogs of Combretastatin A4. AB - The combretastatins are an important class of tubulin-binding agents. Of this family, a number of compounds are potent tumor vascular disrupting agents (VDAs) and have shown promise in the clinic for cancer therapy. We have developed a modular synthetic route to combretastatin analogs based on a pyrazole core through highly regioselective alkyne cycloaddition reactions of sydnones. These compounds show modest to high potency against human umbilical vein endothelial cell proliferation. Moreover, evidence is presented that these novel VDAs have the same mode of action as CA4P and bind reversibly to beta-tubulin, believed to be a key feature in avoiding toxicity. The most active compound from in vitro studies was taken forward to an in vivo model and instigated an increase in tumor cell necrosis. PMID- 27690433 TI - Oregonator Scaling Motivated by Showalter-Noyes Limit. AB - The Belousov-Zhabotinsky (BZ) reaction is the prototype oscillatory chemical system. We investigate here a new scaling of the Oregonator model of BZ chemical kinetics, and use this scaling to elucidate fundamental properties of BZ dynamics. In the Showalter-Noyes criterion for oscillation, that the product [H+][BrO3+] exceed a critical value, arises naturally as a critical value for a subcritical Hopf bifurcation in this setting, as does the reduction to a two variable model. We thus provide chemical explanations of the role of time scales in the BZ reaction.

PMID- 27690434 TI - Passive Membrane Permeability in Cyclic Peptomer Scaffolds Is Robust to Extensive Variation in Side Chain Functionality and Backbone Geometry. AB - Synthetic and natural cyclic peptides provide a testing ground for studying membrane permeability in nontraditional drug scaffolds. Cyclic peptomers, which incorporate peptide and N-alkylglycine (peptoid) residues, combine the stereochemical and geometric complexity of peptides with the functional group diversity accessible to peptoids. We synthesized cyclic peptomer libraries by split-pool techniques, separately permuting side chain and backbone geometry, and analyzed their membrane permeabilities using the parallel artificial membrane permeability assay. Nearly half of the side chain permutations had permeability coefficients (Papp) > 1 * 10-6 cm/s. Some backbone geometries enhanced permeability due to their ability to form more stable intramolecular hydrogen bond networks compared with other scaffolds. These observations suggest that hexameric cyclic peptomers can have good passive permeability even in the context of extensive side chain and backbone variation, and that high permeability can generally be achieved within a relatively wide lipophilicity range.

Nuclear Factor Erythroid 2-Related Factor 2 (KEAP1:NRF2) Protein-Protein Interaction Inhibitors: Achievements, Challenges, and Future Directions.

Recently, directly targeting Keap1-Nrf2 protein-protein interaction (PPI) has been an emerging strategy to selectively and effectively activate Nrf2. This Perspective summarizes the progress in the discovery and development of Keap1-Nrf2 PPI inhibitors, including the Keap1-Nrf2 regulatory mechanisms, biochemical techniques for inhibitor identification, and approaches for identifying peptide and small-molecule inhibitors, as well as discusses privileged structures and future directions for further development of Keap1-Nrf2 PPI inhibitors. PMID- 27690436 TI - Coupled Electron-Nuclear Dynamics on H2+ Within Time-Dependent Born-Oppenheimer Approximation. AB - Quantum dynamical behaviour of H2+ in the presence of linearly polarized, ultrashort, intense, infrared laser pulse has been studied by numerically solving the time-dependent Schrodinger equation with nuclear motion restricted in one dimension along the direction of laser polarization and electronic motion in three-dimensions. Based on time-dependent Born-Oppenheimer approximation, we have constructed time-dependent potentials for the ground electronic state 1ssigmag of H2+. Subsequent nuclear dynamics is then carried out on these field-dressed potential energy surfaces and the dissociation dynamics is investigated. Our analysis reveal that although the electronic longitudinal degree of freedom plays the major role in governing the dissociation dynamics, contribution from the electronic transverse degree of freedom should also have to be taken into account in order to obtain accurate results. Also, modelling electron-nuclei Coulomb interaction in an one dimensional calculation with artificially chosen constant softening parameter leads to discrepancy with the exact results. Comparing our results with other quantum and classical dynamical studies showed a good agreement with exact results. PMID- 27690437 TI - Dynamic Behavior of Secondary Electrons in Liquid Water at the Earliest Stage upon Irradiation: Implications for DNA Damage Localization Mechanism. AB - To clarify the formation of radiation damage in DNA, the dynamic behavior of low energy secondary electrons produced by ionizing radiation in water was studied by using a dynamic Monte Carlo code that considers the Coulombic force between electrons and their parent cations. The calculated time evolution of the mean energy, total track length, and mean traveling distance of the electrons indicated that the prehydration of the electrons occurs competitively with thermalization on a timescale of hundreds of femtoseconds. The decelerating electrons are gradually attracted to their parent cations by Coulombic force within hundreds of femtoseconds, and finally about 12.6% electrons are distributed within 2 nm of the cations. The collision fraction for ionization and electronic excitation within 1 nm of the cation was estimated to be about 40%. If these electrons are decelerated in a living cell, they may cause highly localized lesions around a cation in a DNA molecule through additional dissociative electron transfer (DET) as well as ionization and electronic excitation (EXC), possibly resulting in cell death or mutation.

AB - Flavins are a fundamental class of biomolecules, whose photochemical properties strongly depend on their environment and their redox and metalation state. Infrared multiphoton dissociation (IRMPD) spectra of mass selected isolated metal lumiflavin ionic complexes (M+LF) are analyzed in the fingerprint range (800-1830 cm-1) to determine the bonding of lumiflavin with alkali (M=Li, Na, K, Cs) and coinage (M=Cu, Ag) metal ions. The complexes are generated in an electrospray ionization source coupled to an ion cyclotron resonance mass spectrometer and the IR free electron laser FELIX. Vibrational and isomer assignments of the IRMPD spectra are accomplished by comparison to quantum chemical calculations at the B3LYP/cc-pVDZ level, yielding structure, binding energy, bonding mechanism, and spectral properties of the complexes. The most stable binding sites identified in the experiments involve metal bonding to the oxygen atoms of the two available CO groups of LF. Hence, CO stretching frequencies are a sensitive indicator of both the metal binding site and the metal bond strength. More than one isomer is observed for M=Li, Na, and K, and the preferred CO binding site changes with the size of the alkali ion. For Cs+LF only one isomer is identified although the energies of the two most stable structures differ by less than 7 kJ/mol. While the M+-LF bonds for alkali ions are mainly based on electrostatic forces, substantial covalent contributions lead to stronger bonds for the coinage metal ions. Comparison between lumiflavin and lumichrome reveals substantial differences in the metal binding motifs and interactions due to the different flavin structures.

AB - N-Alkyl 2-pyridones and other enolizable heterocycles are important synthetic constructs, due to their prevalence in natural products and pharmaceutical targets and their capacity to serve as models for a number of biological and chemical processes. The disclosed Au(I)-catalyzed reaction utilizes 2 propargyloxypyridines to access N-alkylated 2-pyridone products derived from both 5-exo and 6-endo addition of the nitrogen to the pendent alkyne. Experimental and computational studies suggest that the desired 5-exo N-alkenyl 2-pyridonyl ethers are formed reversibly in the transformation. After extensive optimization, biaryl Au(I) catalyst 21 was found to overcome the inherent preference for the 6-endo pathway and provide the highest combination of 5-exo selectivity and yield. Herein, we report the application of this new Au(I)-catalyzed C-N bond formation to the preparation of a variety of N-alkenyl 2-pyridonyl ether analogues, which have the potential to serve as an entry point for the synthesis of complex N alkyl 2-pyridone-containing frameworks.

AB - Li and co-workers recently developed a dual C-H bond activation strategy, using a Rh(III) catalyst, for [3 + 2]/[5 + 2] annulation of primary 4-aryl-1,2,3 triazoles and alkynes. The Rh(III)-catalyzed dual annulation of 4-aryl-1,2,3 triazoles and alkynes is challenging because only single annulation is achieved using Rh(II) and Ni(0) catalysts. Intrigued by the novel strategy, we performed a density functional theory study to unravel this challenging dual C-H bond activation. A Friedel-Crafts type mechanism proved be more favorable than a concerted metalation-deprotonation (CMD) mechanism for the first C-H bond activation. The second C-H bond activation proceeded via a CMD mechanism. More importantly, the calculation explained why only AgSbF6, among several candidates, performed perfectly, whereas others failed, and why the dual annulation of 4-aryl 1,2,3-triazoles with alkynes was achieved with a Rh(III) catalyst but not with Rh(II) and Ni(0) catalysts. Due to the active catalyst being [Cp*Rh(OAc)]+, AgSbF6, in which SbF6- is a stable anion, among several candidates performed perfectly. The success of the Rh(III)-catalyzed dual C-H bond activation has two origins: (i) the active catalyst [Cp*Rh(OAc)]+ is more stable than Cp*Rh(OAc)2 when the Ag salt is AgSbF6, and this facilitates the first alkyne insertion; and (ii) a rhodium-carbene is easily formed.

Due to the reaction features' selective introduction of halogen functionalities to the newly formed imidazo ring, further extensions of the developed chemistry toward synthetic diversity, including effective access to functional materials, are easily envisioned. PMID- 27690443 TI - Variations in Rotational Barriers of Allyl and Benzyl Cations, Anions, and Radicals. AB - High accuracy quantum chemical calculations show that the barriers to rotation of a CH2 group in the allyl cation, radical, and anion are 33, 14, and 21 kcal/mol, respectively. The benzyl cation, radical, and anion have barriers of 45, 11, and 24 kcal/mol, respectively. These barrier heights are related to the magnitude of the delocalization stabilization of each fully conjugated system. This paper addresses the question of why these rotational barriers, which at the Huckel level of theory are independent of the number of nonbonding electrons in allyl and benzyl, are in fact calculated to be factors that are of 2.4 and 4.1 higher in the cations and 1.5 and 1.9 higher in the anions than in the radicals. We also investigate why the barrier to rotation is higher for benzyl than for allyl in the cations and in the anions. Only in the radicals is the barrier for benzyl lower than that for allyl, as Huckel theory predicts should be the case. These fundamental questions in electronic structure theory, which have not been addressed previously, are related to differences in electron-electron repulsions in the conjugated and nonconjugated systems, which depend on the number of nonbonding electrons.

AB - IR and Raman spectroscopic technology can be directly used to identify the occurrence of ferroelectric ice XI in laboratory or extraterrestrial settings. The performance of 16 different DFT methods applied on the ice Ih, VIII, IX, and XI crystal phases are evaluated. Based on a selected DFT computational scheme, the IR and Raman spectra of ice Ih and XI are derived and compared. When comparing the spectra of ice Ih and ice XI, both IR and Raman, the librational vibrations are found to be the most affected by the proton ordering. The spectroscopic fingerprint of ice XI can be used to distinguish ferroelectric ice XI from ice Ih in the universe. Furthermore, the existence of only one kind of H bond in ice Ih is demonstrated from the overlapping sub-spectra for different types of H-bonded pair configurations in 16 isomers of ice Ih, which provides an illustration to the historic debate on whether one or two kinds of H-bonds existed in ice. PMID- 27690445 TI - A Chemical Activation Study of the Unimolecular Reactions of CD3CD2CHCl2 and CHCl2CHCl2 with Analysis of the 1,1-HCl Elimination Pathway. AB - Chemically activated C2D5CHCl2 molecules were generated with 88 kcal mol-1 of vibrational energy by the recombination of C2D5 and CHCl2 radicals in a room temperature bath gas. The competing 2,1-DCl and 1,1-HCl unimolecular reactions were identified by the observation of the CD3CD=CHCl and CD3CD=CDCl products. The initial CD3CD2C-Cl carbene product from 1,1-HCl elimination rearranges to CD3CD=CDCl under the conditions of the experiments. The experimental rate constants were 2.7 x107 and 0.47 x107 s-1 for 2,1-DCl and 1,1-HCl elimination reactions, respectively, which corresponds to branching fractions of 0.84 and 0.16. The experimental rate constants were compared to calculated statistical rate constants to assign threshold energies of 54 and ~ 66 kcal mol-1 for the 1,2 DCl and 1,1-HCl reactions, respectively. The statistical rate constants were obtained from models developed from electronic-structure calculations for the molecule and its transition states. The rate constant (5.3 x 107 s-1) for the unimolecular decomposition of CHCl2CHCl2 molecules formed with 82 kcal mol-1 of vibrational energy by the recombination of CHCl2 radicals also is reported. Based upon the magnitude of the calculated rate constant, 1,1-HCl elimination must contribute less than 15% to the reaction; 1,2-HCl elimination is the major reaction and the threshold energy is 59 kcal mol-1. Calculations also were done to analyze previously published rate constants for chemically activated CD2Cl CHCl2 molecules with 86 kcal mol-1 of energy in order to obtain a better overall description of the nature of the 1,1-HCl pathway for 1,1-dichloroalkanes. The interplay of the threshold energies for the 2,1-HCl and 1,1-HCl reactions and the available energy determines the product branching fractions for individual molecules. The unusual nature of the transition state for 1,1-HCl elimination is discussed. PMID- 27690446 TI - Molecular Recognition of tRNA with 1-Naphthyl Acetyl Spermine, Spermine and Spermidine: A Thermodynamic, Biophysical and Molecular Docking Investigative Approach. AB - A major thrust of anticancer therapeutics is the dynamic quest for small molecules that binds and modifies nucleic acids and proteins effectively. The role of tRNA in the protein translational machinery and the influence of polyamines on the interaction of acylated and deacylated tRNA to ribosomes,47-48 make polyamine-tRNA interactions conspicuous. Therefore, we have studied the interaction of two biogenic polyamines spermine and spermidine with tRNAPhe and compared the interaction with the polyamine analog, 1-naphthyl acetyl spermine to fathom the thermodynamic and structural basis of the binding interaction. The binding affinity of spermine was comparable to 1-naphthyl acetyl spermine and both were greater than spermidine. The interactions led to significant thermal stabilization of the tRNAPhe and an increase in the enthalpy of transition. All the interactions were exothermic in nature and displayed prominent enthalpy entropy compensation behavior. The entropy driven nature of the interaction, the structural perturbations observed in circular dichroism spectra and docking results proved that the polyamines were bound in the groove of the anticodon arm of tRNAPhe. The amine groups in the polyamines were involved in extensive electrostatic, H-bonding and van der Waals interactions with the tRNAPhe molecule. The naphthyl group of 1-naphthyl acetyl spermine made additional stacking interaction with G24 and G26 of tRNAPhe, which was absent in the case of spermine and spermidine. Thus, the results demonstrate that the polyamine analog has a strong capability to target the same binding sites as biogenic polyamines but without substituting for the functions played by them, which may lead to exhibition of selective anti-cancer cytotoxicity. Therefore, this study on the interaction of 1-napthyl acetyl spermine with tRNAPhe potentiates further development of this analog as an anti-cancer therapeutic.

AB - The mononuclear rearrangement of heterocycles (MRH) reaction of the Z phenylhydrazone of 3-benzoyl-5-phenyl-1,2,4-oxadiazole into 4-benzoylamino-2,5 diphenyl-1,2,3-triazole derives a sizable rate enhancement in the 1-butyl-3 methylimidazolium tetrafluoroborate [BMIM][BF4] ionic liquid as compared to the hexafluorophosphate-based [BMIM][PF6] and conventional organic solvents. However, the origin of the rate difference between [BMIM][BF4] and [BMIM][PF6] has proven difficult to rationalize as no experimental trend relates the physical properties of the solvents, e.g., polarity and viscosity, to the rates of reaction. QM/MM calculations in combination with free-energy perturbation theory and Monte Carlo sampling have been carried out for the MRH reaction to elucidate the disparities in rates when using ionic liquids, methanol, and acetonitrile. Activation barriers and solute-solvent interactions have been computed for both an uncatalyzed and a specific base-catalyzed mechanism. Energetic and structural analyses determined that favorable pi+-pi interactions between the BMIM cation, the substrate phenyl rings, and the bicyclic quasi-aromatic 10pi oxadiazole/triazole transition state region imposed a pre-ordered geometric arrangement that enhanced the rate of reaction. An ionic liquid clathrate formation enforced a coplanar orientation of the phenyl rings that maximized the electronic effects exerted on the reaction route. In addition, site-specific electrostatic stabilization between the ions and the MRH substrate was more prevalent in [BMIM][BF4] as compared to [BMIM][PF6].

AB - The hyperpolarization-activated cyclic-nucleotide-modulated (HCN) ion channels control rhythmicity in neurons and cardiomyocytes. Cyclic AMP (cAMP) modulates HCN activity through cAMP-dependent formation of a tetrameric gating ring spanning the intracellular region (IR) of HCN. In the absence of cAMP, the IR cAMP-binding domain (CBD) mainly samples its inactive conformation, resulting in steric clashes that destabilize the IR tetramer. Although these clashes with the inactive CBD are released through tetramer dissociation into monomers, functional mutagenesis suggests that the apo IR is not fully monomeric. To investigate the inhibitory non-monomeric IR species, we performed molecular dynamics simulations starting from "hybrid" structures that are tetrameric, but contain inactive apo state CBD conformations. The ensemble of simulated trajectories reveals that full dissociation of the tetramer into monomers is not necessary to release the steric hindrance with the inactive CBD. Specifically, we found that partial dissociation of the tetramer into dimers is sufficient to accommodate four inactive CBDs, while reduction of the quaternary symmetry of the non-dissociated tetramer from four- to two-fold permits accommodation of two inactive CBDs. Our findings not only rationalize available electrophysiological, fluorometry and sedimentation equilibrium data, but they also provide unprecedented structural insight into previously elusive non-monomeric auto-inhibitory HCN species.

AB - Biomimetic nanopores with rectifying properties are relevant components of ionic switches, ionic circuits, and biological sensors. Rectification indicates that currents for voltages of one polarity are higher than currents for voltages of the opposite polarity. Ion current rectification requires the presence of surface charges on the pore walls, achieved either by the attachment of charged groups, or in multi-electrode systems by applying voltage to integrated gate electrodes. Here, we present a simpler concept for introducing surface charges via polarization of a thin layer of Au present at one entrance of a silicon nitride nanopore. In an electric field applied by two electrodes placed in bulk solution on both sides of the membrane, the Au layer polarizes such that excess positive charge locally concentrates at one end and negative charge at the other end. Consequently, a junction is formed between zones with enhanced anion and cation concentrations in the solution adjacent to the Au layer. This bipolar double layer together with enhanced cation concentration in a negatively charged silicon nitride nanopore leads to voltage-controlled surface-charge patterns and ion current rectification. The experimental findings are supported by numerical modeling that confirm modulation of ionic concentrations by the Au layer and ion current rectification even in low-aspect ratio nanopores. Our findings enable a new strategy for creating ionic circuits with diodes and transistors.

AB - Synthetic molecules that bind sequence-specifically to DNA have been developed for varied biological applications, including anticancer activity, regulation of gene expression, and visualization of specific genomic regions. Increasing the number of base pairs targeted by synthetic molecules strengthens their sequence specificity. Our group has been working on the development of pyrrole-imidazole polyamides that bind to the minor groove of DNA in a sequence-specific manner without causing denaturation. Recently, we reported a simple synthetic method of fluorescent tandem dimer polyamide probes composed of two hairpin moieties with a linking hinge, which bound to 12 bp in human telomeric repeats (5'-(TTAGGG)n-3') and could be used to specifically visualize telomeres in chemically fixed cells under mild conditions. We also performed structural optimization and extension of the target base pairs to allow more specific stain-ing of telomeres. In the present study, we synthesized tandem tetramer polyamides composed of four hairpin moieties, targeting 24 bp in telomeric repeats, the longest reported binding site for synthetic, non-nucleic-acid-based, sequence-specific DNA-binding molecules. The novel tandem tetramers bound with a nanomolar dissociation constant to 24 bp sequences made up of four telomeric repeats. Fluorescently labeled tandem tetramer polyamide probes could visualize human telomeres in chemically fixed cells with lower background signals than polyamide probes reported previously, suggesting that they had higher specificity for telomeres. Furthermore, high throughput sequencing of human genomic DNA pulled down by the biotin-labeled tandem tetramer polyamide probe confirmed its effective binding to telomeric repeats in the complex chromatinized genome.

AB - Coupled cluster theory with single, double and perturbative triple excitations (CCSD(T)) is widely considered to be the 'gold standard' of ab initio quantum chemistry. Using the domain-based pair natural orbital local correlation concept (DLPNO-CCSD(T)), these calculations can be performed on systems with hundreds of atoms at an accuracy of about 99.9% of the canonical CCSD(T) method. This allows for ab initio calculations providing reference adsorption energetics at solid surfaces with an accuracy approaching 1 kcal/mol. This is an invaluable asset, not least for the assessment of density-functional theory (DFT) as the prevalent approach for large-scale production calculations in energy or catalysis applications. Here we use DLPNO-CCSD(T) with embedded cluster models to compute entire adsorbate potential energy surfaces for the binding of a set of prototypical closed-shell molecules (H2O, NH3, CH4, CH3OH, CO2) to the rutile TiO2(110) surface. The DLPNO-CCSD(T) calculations show excellent agreement with available experimental data, even for the 'infamous' challenge of correctly predicting the CO2 adsorption geometry. The numerical efficiency of the approach is within one order of magnitude of hybrid-level DFT calculations, hence blurring the borders between reference and production technique.

AB - Physiological stimuli such as thrombin, or pathological stimuli such as lysophosphatidic acid (LPA), activate platelets. The activated platelets bind to monocytes through P-selectin-PSGL-1 interactions but also release the contents of their granules, commonly called "platelet releasate". It is known that monocytes in contact with platelet releasate produce reactive oxygen species (ROS). Reversible cysteine oxidation by ROS is considered to be a potential regulator of protein function. In a previous study, we used THP-1 monocytic cells exposed to LPA- or thrombin-induced platelet releasate and a modified biotin switch assay to unravel the biological processes that are influenced by reversible cysteine oxidation. To gain a better understanding of the redox regulation of monocytes in atherosclerosis, we have now altered the modified biotin switch to selectively quantify protein sulfenic acid, a subpopulation of reversible cysteine oxidation. Using arsenite as reducing agent in the modified biotin switch assay, we were able to quantify 1161 proteins, in which more than 100 sulfenic acid sites were identified. Bioinformatics analysis of the quantified sulfenic acid sites highlighted the relevant, previously missed biological process of monocyte transendothelial migration, which included integrin beta2. Flow cytometry validated the activation of LFA-1 (alphaLbeta2) and Mac-1 (alphaMbeta2), two subfamilies of integrin beta2 complexes, on human primary monocytes following platelet releasate treatment. The activation of LFA-1 was mediated by ROS from NADPH oxidase (NOX) activation. Production of ROS and activation of LFA-1 in human primary monocytes were independent of P-selectin-PSGL-1 interaction. Our results proved the modified biotin switch assay to be a powerful tool with the ability to reveal new regulatory mechanisms and identify new therapeutic targets. PMID- 27690454 TI - Encapsulation and controlled release of rapamycin from polycaprolactone nanoparticles prepared by membrane micromixing combined with antisolvent precipitation. AB - Rapamycin loaded polycaprolactone nanoparticles (RAPA-PCL NPs) with a low polydispersity index of 0.006-0.073 were produced by anti-solvent precipitation using a ringed stainless steel membrane with 10-MUm diameter laser-drilled pores. The organic phase composed of 6 g L-1 of PCL and 0.6-3.0 g L-1 of RAPA in acetone was injected through the membrane at 140 L m-2 h-1 into 0.2 wt% aqueous polyvinyl alcohol solution stirred at 1300 rpm, resulting in a Z-average mean of 189-218 nm, a drug encapsulation efficiency of 98.8-98.9 % and a drug loading in the NPs of 9-33 %. The encapsulation of RAPA was confirmed by UV-Vis spectroscopy, XRD, DSC, and ATR-FTIR. The disappearance of sharp characteristic peaks of crystalline RAPA in the XRD pattern of RAPA-PCL NPs revealed that the drug was molecularly dispersed in the polymer matrix or present in individual amorphous domains. The rate of drug release in pure water was negligible due to low aqueous solubility of RAPA. RAPA-PCL NPs released more than 91 % of their drug cargo after 2.5 h in the release medium composed of 0.78-1.5 M of the hydrotropic agent N,N diethylnicotinamide (DENA), 10 vol% of ethanol, and 2 vol% of Tween 20 in phosphate buffered saline. The release rate of RAPA was faster when the concentra tion of DENA in the dissolution medium was higher. The dissolution of RAPA was slower when the drug was embedded in the PCL matrix of the NPs than dispersed in the form of pure RAPA nanocrystals. PMID- 27690456 TI - Molecular organization of an adsorbed layer: a zwitterionic, pH-sensitive surfactant at the air/water interface. AB - Neutron and X-ray reflection measurements have been used to study the structure of the adsorbed layer of a chelating surfactant at the air/liquid interface. The chelating surfactant 2-dodecyldiethylenetriaminepentaacetic acid (C12-DTPA) has a large head group containing eight donor atoms that can participate in the coordination of metal ions. The donor atoms are also titrating, resulting in an amphoteric surfactant that can adopt a number of differently charged species depending on the pH. Very strong coordination complexes are formed with metal ions, where the metal ion can be considered as part of the surfactant structure, in contrast to monovalent cations that act as regular counter-ions to the negative net charge. Adsorption was investigated over a large concentration interval, from well below the critical micelle concentration (cmc) to five times the cmc. The most striking result is the maximum in the surface excess found around the cmc, which is consistent with previous indications from surface tension measurements. Adding divalent metal ions has a limited effect on the adsorption at the air/liquid interface. The reason is the coordination of the metal ion, resulting in compensating deprotonation of the complex. Small variations in the head group area of different metal complexes are found, correlating to the conditional stability constants. Adding sodium chloride has a significant effect on the adsorption behavior and the results indicate that the protonation equilibrium is more important than the ionic strength effects. From combined fits of the neutron and X-ray data, a model that consists of a thick head group region and a relatively thin dehydrated tail region is found, and it indicates that the tails are not fully extended and that the limiting area per molecule is determined by the bulky head group. PMID- 27690455 TI - Tracking the Antibody Immunome in Type 1 Diabetes Using Protein Arrays. AB - We performed an unbiased proteome-scale profiling of humoral autoimmunity in recent-onset type 1 diabetes (T1D) patients and nondiabetic controls against ~10 000 human proteins using a Nucleic Acid Programmable Protein Array (NAPPA) platform, complemented by a knowledge-based selection of proteins from genes enriched in human pancreas. Although the global response was similar between cases and controls, we identified and then validated six specific novel T1D associated autoantibodies (AAbs) with sensitivities that ranged from 16 to 27% at 95% specificity. These included AAbs against PTPRN2, MLH1, MTIF3, PPIL2, NUP50 (from NAPPA screening), and QRFPR (by targeted ELISA). Immunohistochemistry demonstrated that NUP50 protein behaved differently in islet cells, where it stained both nucleus and cytoplasm, compared with only nuclear staining in exocrine pancreas. Conversely, PPIL2 staining was absent in islet cells, despite its presence in exocrine cells. The combination of anti-PTPRN2, -MLH1, -PPIL2, and -QRFPR had an AUC of 0.74 and 37.5% sensitivity at 95% specificity. These data indicate that these markers behave independently and support the use of unbiased screening to find biomarkers because the majority was not predicted based on predicted abundance. Our study enriches the knowledge of the "autoantibody-ome" in unprecedented breadth and width. PMID- 27690458 TI - Correction to Highly Dense Cu Nanowires for Low-Overpotential CO2 Reduction.

AB - We demonstrate a robust and tunable micromolding method to fabricate chemically functional poly(acrylamide-co-acrylic acid) (p(AAm-co-AA)) hydrogel microspheres with uniform dimensions and controlled porous network structures for rapid biomacromolecular conjugation. Specifically, p(AAm-co-AA) microspheres with abundant carboxylate functional groups are fabricated via surface tension-induced droplet formation in patterned poly(dimethylsiloxane) (PDMS) molds and photo induced radical polymerization. To demonstrate chemical functionality, we enlisted a rapid EDC/NHS (1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and N-hydroxysuccinimide (NHS)) chemistry for fluorescent labeling of the microspheres with a small molecule dye fluorescein glycine amide. Epifluorescence imaging results illustrate the uniform incorporation of carboxylate groups within the microspheres and rapid conjugation kinetics. Furthermore, protein conjugation results using red fluorescent protein R-phycoerythrin demonstrate highly porous nature of the microspheres as well as the utility of the microspheres and the EDC/NHS scheme for facile biomacromolecular conjugation. Combined, these results illustrate significant potential for our fabrication-conjugation strategy in the development of biofunctionalized polymeric hydrogel microparticles toward rapid biosensing, bioprocess monitoring, and biodiagnostics. PMID- 27690457 TI - Maximizing Headgroup Repulsion: Hybrid Surfactants with Ultrahighly Charged Inorganic Heads and Their Unusual Self-Assembly. AB - Nonequilibrium states of matter are arousing huge interest because of the outstanding possibilities to generate unprecedented structures with novel properties. Self-organizing soft matter is the ideal object of study as it unifies periodic order and high dynamics. Compared to settled systems, it becomes vital to realize more complex interaction patterns. A promising and intricate approach is implementing controlled balance between attractive and repulsive forces. We try to answer a fundamental question in surfactant science: How are processes like lyotropic liquid crystals and micellization affected, when headgroup charge becomes so large that repulsive interactions are inevitable? A particular challenge is that size and shape of the surfactant must not change. We could realize the latter by means of new hybrid surfactants with a heteropolyanion head [EW11O39]n- (E = PV, SiIV, BIII; n = 3, 4, 5). Among the unusual self-assembled structures, we report a new type of micelle with dumbbell morphology. PMID- 27690461 TI - Interactions of sulfobetaine zwitterionic surfactants with water on water surface. AB - We carried out a combined study using surface tension, phase-sensitive frequency generation (SFG) vibrational spectroscopy, and MD simulations to investigate the industrially-relevant zwitterionic surfactant N-dodecyl-N, N-dimethyl-3-ammonio-1 propanesulfonate (DDAPS) on water surface. The SFG Im(chi(2)) spectra showed that the interaction between DDAPS and water was different from those between biologically-relevant zwitterionic phospholipids and water. While zwitterionic phospholipids were found to be anionic-like and flipped water molecules with their OHs pointing toward the air, DDAPS oriented water molecules with their OHs mostly pointing toward the liquid water. We built a new force field for the MD simulation which produced the correct surface tension of water with various DDPAS coverage. The MD simulation showed that the head groups of DDPAS were nearly parallel to the water surface. When the surface coverage of DDPAS was increased, the averaged tilting angle of DDPAS's tails decreased but it had little effect on the orientation of the head group. The sulfobetaine zwitterionic surfactant was found to be more cationic-like because the positively charged group was more capable of orienting interfacial water. PMID- 27690460 TI - Synthesis, in Vitro Evaluation, and Radiolabeling of Fluorinated Puromycin Analogues: Potential Candidates for PET Imaging of Protein Synthesis. AB - There is currently no ideal radiotracer for imaging of protein synthesis rate (PSR) by positron emission tomography (PET). Existing fluorine-18-labeled amino acid-based radiotracers predominantly visualize amino acid transporter processes, and in many cases they are not incorporated into nascent proteins at all. Others are radiolabeled with the short-half-life positron emitter carbon-11, which is rather impractical for many PET centers. Based on the puromycin (6) structural manifold, a series of 10 novel derivatives of 6 was prepared via Williamson ether synthesis from a common intermediate. A bioluminescence assay was employed to study their inhibitory action on protein synthesis, which identified the fluoroethyl analogue 7b as a lead compound. The fluorine-18 analogue was prepared via nucleophilic substitution of the corresponding tosylate precursor in a modest radiochemical yield of 2 +/- 0.6% with excellent radiochemical purity (>99%) and showed complete stability over 3 h at ambient temperature. PMID- 27690462 TI - Dielectric and Mechanical Investigations on the Hydrophilicity and Hydrophobicity of Polyethylene Oxide Modified on a Silicon Surface. AB - Polyethylene oxide (PEO) has been widely used in biomedical fields. The antibiofouling property of the PEO-modified surface has been extensively investigated but is far from being fully understood. A series of PEOs with narrowly distributed molecular weight (Mw), synthesized with the technique of high vacuum anionic polymerization, have been successfully grafted onto the surface of silicon wafers. The power-law relationship between the thickness of the monolayer versus the Mw of the grafted PEO shows a scaling of 0.3, indicating compact condensing of the chains. The static contact angles show higher hydrophobicity for the layer of PEO with higher Mw, which can be attributed to the closely packed conformation of the chains with high density. The frequency shift of the contact resonance indicates that the Young's modulus decreases and the loss factor increases with the increase in the Mw of PEO and the thickness of the PEO layers. Dielectric spectroscopy of bare or PEO-grafted wafers in the aqueous solutions reveals an interfacial polarization, which results from compositional and structural changes in the interface layer and depends on temperatures and salt concentrations. At a given grafting density, the PEO chains are swollen in pure water, demonstrating hydrophilic behavior, whereas they collapse in salt solutions, showing hydrophobic characteristics.

AB - A practical synthesis of the orthogonally protected d- and l-beta hydroxyenduracididines (d- and l-betahEnds), the unique, nonproteinogenic alpha amino acids found in mannopeptimycin antibiotics, is described. We appropriately applied d-lyxono-1,4-lactone derivatives as a starting template and investigated two transformations: (i) reduction of the lactone in a two-step sequence and (ii) regioselective ring opening of the benzylidene acetal. By careful evaluation of reaction conditions, multigram amounts of both orthogonally protected d- and l betahEnds were successfully prepared. PMID- 27690464 TI - Near Axisymmetric Partial Wetting Using Interface-Localized Liquid Dielectrophoresis. AB - The wetting of solid surfaces can be modified by altering the surface free energy balance between the solid, liquid, and vapor phases. Liquid dielectrophoresis (L DEP) can produce wetting on normally nonwetting surfaces, without modification of the surface topography or chemistry. L-DEP is a bulk force acting on the dipoles of a dielectric liquid and is not normally considered to be a localized effect acting at the interface between the liquid and a solid or other fluid. However, if this force is induced by a nonuniform electric field across a solid-liquid interface, it can be used to enhance and control the wetting of a dielectric liquid. Recently, it was reported theoretically and experimentally that this approach can cause a droplet of oil to spread along parallel interdigitated electrodes thus forming a stripe of liquid. Here we show that by using spiral shaped electrodes actuated with four 90 degrees successive phase-shifted signals, a near axisymmetric spreading of droplets can be achieved. Experimental observations show that the induced wetting can achieve film formation, an effect not possible with electrowetting. We show that the spreading is reversible thus enabling a wide range of partial wetting droplet states to be achieved in a controllable manner. Furthermore, we find that the cosine of the contact angle has a quadratic dependence on applied voltage during spreading and deduce a scaling law for the dependence of the strength of the effect on the electrode size.

AB - Percolation dealloying of multimetallic alloys entangles the selective dissolution of the less-noble elements with nanoscale restructuring of the more noble components, resulting in the formation of spongelike, nanoporous architectures with a unique set of structural characteristics highly desirable for heterogeneous catalysis. Although the dealloyed nanoporous materials are compositionally dominated by the more-noble elements, they inevitably contain residual less-noble elements that cannot be completely removed through the percolation dealloying process. How to employ the less-noble elements to rationally guide the structural evolution and optimize the catalytic performances of the dealloyed noble metal nanocatalysts still remains largely unexplored. Here, we have discovered that incorporation of Ag into Au-Cu binary alloy nanoparticles substantially enhances the Cu leaching kinetics while effectively suppressing the ligament coarsening during the nanoporosity-evolving percolation dealloying of the alloy nanoparticles. The controlled coleaching of Ag and Cu from Au-Ag-Cu ternary alloy nanoparticles provides a unique way to optimize both the surface area-to-mass ratios and specific activities of the dealloyed nanosponge particles for the electrocatalytic oxidation of alcohols. The residual Ag in the fully dealloyed nanosponge particles plays crucial roles in stabilizing the surface active sites and maintaining the nanoporous architectures during the electrocatalytic reactions, thereby greatly enhancing the durability of the electrocatalysts. The insights gained from this work shed light on the underlying roles of residual less-noble elements that are crucial to the rational optimization of electrocatalysis on noble-metal nanostructures.

An organocatalyzed IOM reaction of in situ formed peroxy hemiacetals followed by a Kornblum DeLaMare type rearrangement cascade provides a broad class of chiral lactones in good yields and with excellent enatioselectvities.

PMID- 27690468 TI - Probing the Interaction between a DNA Nucleotide (Adenosine-5'-Monophosphate Disodium) and Surface Active Ionic Liquids by Rotational Relaxation Measurement and Fluorescence Correlation Spectroscopy. AB - This article demonstrates the interaction of a deoxyribonucleic acid (DNA) nucleotide, adenosine-5'-monophosphate disodium (AMP) with a cationic surface active ionic liquid (SAIL) 1-dodecyl-3-methylimidazoium chloride (C12mimCl) and an anionic SAIL, 1-butyl-3-methylimidazolium n-octylsulfate ([C4mim][C8SO4]). Dynamic light scattering (DLS) measurements and 1H NMR (nuclear magnetic resonance) studies indicate that substantial interaction is taking place among the DNA nucleotide, AMP and the SAILs. Moreover, cryogenic transmission electron microscopy (cryo-TEM) suggests that SAILs containing micellar assemblies are transformed into larger micellar assemblies in presence of DNA nucleotide. Additionally, the rotational motion of two oppositely charged molecules, Rhodamine 6G perchlorate (R6G) and Fluorescein sodium salt (Fl-Na) have been monitored in these aggregates. The rotational motion of R6G and Fl-Na differs significantly between SAILs micelles, and SAILs-AMP containing larger micellar aggregates. The effect of negatively charged DNA nucleotide (AMP) addition into the cationic and anionic SAILs is more prominent for the cationic charged molecule R6G than that of anionic probe Fl-Na due to the favourable electrostatic interaction between the AMP and cationic R6G. Moreover, the influence of the anionic DNA nucleotide on the cationic and anionic SAIL micelles is monitored through the variation of the lateral diffusion motion of oppositely charged probe molecules (R6G and Fl-Na) inside these aggregates. This variation in diffusion coefficient values also suggests that interaction pattern of these oppositely charged probes are different within the SAILs-nucleotide containing aggregates. Therefore, both rotational and translational diffusion measurements confirm that the DNA nucleotide (AMP) renders more rigid microenvironment within the micellar solution of SAILs. PMID- 27690469 TI - A Reaction Valley Investigation of the Cycloaddition of 1,3-Dipoles with the Dipolarophiles Ethene and Acetylene - Solution of a Mechanistic Puzzle. AB - The reaction mechanism of the cycloaddition of ten 1,3-dipoles with the two dipolarphiles ethene and acetylene is investigated and compared using the unified reaction valley approach (URVA) in a new form, which is based on a dual level strategy, an accurate description of the reaction valley far out into the van der Waals region, and a comparative analysis of the electronic properties of the reaction complex. A detailed one-to-one compar- ison of 20 different 1,3-dipolar cycloadditions is carried out and so far unknown mechanistic features are revealed. There are significant differences in the reaction mechanisms for the two dipolarophiles that result from the van der Waals complex formation in the entrance channel of the cycloadditions. Hydrogen bonding between the 1,3-dipole and acetylene is generally stronger, which leads to higher reaction barriers in the acetylene case. Elementary differences are found with regard to charge transfer, charge polarization, rehybridization, and bond formation of the two dipolarophiles, which explain their different reaction energies. It is shown that similarities in the reaction barriers as determined by CCSD(T)-F12/aug-cc- pVTZ calculations are accidental because of a fortuitous cancellation of different electronic effects. In general, a caveat has to be made with regard to oversimplified descriptions of the reaction mechanism based on orbital theory or energy decomposition schemes.

AB - Urticaria is a common skin condition that can compromise quality of life and may affect individual performance at work or school. Remission is common in majority of patients with acute spontaneous urticaria (ASU); however, in chronic cases, less than 50% had remission. Angioedema either alone or with urticaria is associated with a much lower remission rate. Proper investigation and treatment is thus required. This guideline, a joint development of the Dermatological Society of Thailand, the Allergy, Asthma, and Immunology Association of Thailand and the Pediatric Dermatological Society of Thailand, is graded and recommended based on published evidence and expert opinion. With simple algorithms, it is aimed to help guiding both adult and pediatric physicians to better managing patients who have urticaria with/without angioedema. Like other recent guideline, urticaria is classified into spontaneous versus inducible types. Patients present with angioedema or angioedema alone, drug association should be excluded, acetyl esterase inhibitors (ACEIs) and non-steroidal anti-inflammatory drugs (NSAIDs) in particular. Routine laboratory investigation is not cost-effective in chronic spontaneous urticaria (CSU), unless patients have clinical suggesting autoimmune diseases. Non-sedating H1-antihistamine is the first-line treatment for 2-4 weeks; if urticaria was not controlled, increasing the dose up to 4 times is recommended. Sedating first-generation antihistamines have not been proven more advantage than non-sedating antihistamines. The only strong evidence-based alternative regimen for CSU is an anti-IgE: omalizumab; due to very high cost it however might not be accessible in low-middle income countries. Non pharmacotherapeutic means to minimize hyper-responsive skin are also important and recommended, such as prevention skin from drying, avoidance of hot shower, scrubbing, and excessive sun exposure.

AB - Autoantibodies directed against various self-antigens comprise a heterogeneous group of immunoglobulins, which differ in their qualitative and quantitative features. An important qualitative characteristic of antibodies is affinity/avidity, which changes in the process of its maturation during the immune response.This study is aimed to summarize the knowledge about avidity of selected autoantibodies in certain autoimmune diseases. The avidity of various autoantibodies differs under distinct clinical situations. High-, moderate or low avidity may be found in biological fluids in patients with autoimmune diseases.The avidity maturation associated with progression from low to high values typical for antibodies against exogenous antigens is not always uniform in autoimmune diseases; therefore, the avidity of each autoantibody should be judged individually. Some studies promise the possible benefit of avidity examination for the refinement of diagnosis and prediction of selected autoimmune diseases.Key words: affinity - anti-citrullinated protein antibodies - anti glomerular basement membrane antibodies - anti-glutamate decarboxylase antibodies - anti-insulin antibodies - autoantibodies - avidity - onconeuronal antibodies. PMID- 27690473 TI - [The incidence of viral hepatitis A in the Hradec Kralove Region in the Czech Republic in the last decade]. AB - OBJECTIVE: Viral hepatitis A continues to occur in the Czech Republic due to the high susceptibility of the population and existing opportunities for the transmission of the disease. The aim was to describe and analyse the incidence of viral hepatitis A in the Hradec Kralove Region in the Czech Republic in 2005 2014, including the study of two outbreaks that required a different approach of field epidemiologists. MATERIAL AND METHODS: In 2015, a retrospective analysis was carried out of the data on the incidence of viral hepatitis A in Hradec Kralove Region in 2005-2014. The EPIDAT system where cases of infectious diseases and data from epidemiological investigations are reported was used as a data source for the purposes of the present analysis. In addition, two final reports on epidemic outbreaks of viral hepatitis A from 2014 were assessed. RESULTS: The incidence of viral hepatitis A at the regional level follows, to a certain extent, the pattern of the incidence of this disease at the national level. The highest number of cases was reported in 2010 due to a country-wide epidemic. The most affected age groups were children, adolescents, and young adults. The incidence of viral hepatitis A in individual years has a significant effect on the emergence of local outbreaks. CONCLUSION: The incidence of viral hepatitis A in the Czech Republic has a fluctuating trend, at both the national and regional levels. The highest incidence of viral hepatitis A was observed in the younger and middle-age categories. The high susceptibility of these population groups suggests the importance of vaccination against viral hepatitis A that confers specific personal protection.Key words: viral hepatitis A - incidence - outbreak Czech Republic.

AB - OBJECTIVE: The study aimed at determining the ability of lipophosphonoxin DR5026 to inhibit the formation of bacterial biofilm on the bone cement surface and assessing potential development of bacterial resistance. MATERIAL AND METHODS: Bone cement (Hi-Fatigue Bone Cement 2x40, aap Biomaterials GmbH, Germany) was polymerized with lipophosphonoxin DR5026. Cement samples were cultured using bacterial suspension containing Staphylococcus epidermidis CCM7221 at an inoculum density of 106 CFU/mL. After three, 24, and 48 hours of incubation at 35 degrees C, the number of bacteria adhered to the sample was measured and their growth curve was plotted. In 14 cycles, strains of Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, and Streptococcus agalactiae were exposed to subinhibitory concentrations of DR5026 and the minimum inhibitory concentrations (MICs) were determined. RESULTS: After three hours of culture in the bacterial inoculum with an initial concentration of 106 CFU/mL, the number of colonies isolated from the cement sample treated with DR5026 was smaller by two orders of magnitude when compared to a control cement sample. After 24 and 48 hours of incubation, the number of CFU remained at 50 in the treated cement, whereas 109 CFU were cultured from control cement samples. The plotted growth curves for bacteria adhered to cements clearly showed the inhibitory effect of lipophosphonoxin on their growth and multiplication, particularly after 48 hours. Following 14 cycles of repeated exposure to subinhibitory concentrations of DR5026, no increase in MICs was noted in the tested strains. CONCLUSION: Lipophosphonoxin DR5026 used to treat bone cement was found to have antibacterial effects and to inhibit the formation of bacterial biofilm. Repeated exposure of the tested bacteria to subinhibitory concentrations of the above lipophosphonoxin did not induce their resistance or increase their MICs.Key words: bone cement - joint replacement infections - lipophosphonoxins - antibacterial effect - biofilm.

It affects mainly the skin and mucous membranes. It is a rare condition with a high mortality rate. Fatal outcomes in patients with TEN are mostly due to infectious complications. As antimicrobial drugs may induce this syndrome, the management of this condition is very complicated. Tigecycline is still a relatively new antibiotic approved in Europe for use in complicated intra-abdominal infections and complicated skin and soft tissue infections. Among major advantages of tigecycline in patients with TEN are its good penetrability into tissues, wide spectrum of activity that makes it suitable for use as monotherapy, and last but not least, in comparison with other antimicrobials, a very low potential for exacerbation of the severity of the underlying disease by further stimulation of the immune system. A case report is presented of a successful management of an 81-year-old woman with TEN and multiple infectious complications in different anatomic locations, the most serious of which was ventilator-associated pneumonia caused by Stenotrophomonas maltophilia. Her general condition was further aggravated by Clostridium colitis. Tigecycline was used as the therapeutic option for ventilator-associated pneumonia, although prescribed off-label.Key words: toxic epidermal necrolysis - tigecycline - off label indications - Clostridium colitis.

Ixodes ricinus ticks and genospecies of Borrelia burgdorferi sensu lato complex. AB - STUDY OBJECTIVE: Three years long research study (2011-2013) on population density of Ixodes ricinus and the infection rate of the pathogens that they transmit was conducted in four topographically distant areas in the Czech Republic. In the previous decade (2001-2010) thirteen loci with increased incidence of tick borne encephalitis cases were defined, suggesting the permanent interaction of human population with ticks and indicating the landmarks for study of the presence of other tick borne pathogens. The work program included the identification of existing spectrum of spirochetes from Borrelia burgdorferi sensu lato complex and the conditions of their occurrence and distribution. MATERIAL AND METHODS: In the areas of the Usti nad Labem Region, Olomouc Region, South Bohemian Region, and Highlands Region, 600 m2 plots were selected in the local optimal I. ricinus habitats where tick flagging was performed every year in the spring-summer and autumn seasons of the tick questing activity. Collected adult ticks (1369 males and 1404 females) were individually screened for B. burgdorferi s. l. spirochets. RESULTS: Spirochetes from B. burgdorferi s.l. complex were detected in all 13 studies sites in all altitudes from 280 to 1030 meters a. s. l. The total rate of infection was determined as 11.4% (males 10.4%, females 12.4%) with range limits from 1.4% (Usti nad Labem in 2011) to 19.7% (South Bohemian Region, 2012).Genospecies were detected in various proportions and in different combinations: Borrelia afzelii, B. garinii, B. burgdorferi s. s., B. bavariensis, B. bissettii, B. valaisiana, B. spielmanii and B. lusitaniae. The three-year observation justifies the assumption that the regional differences in infectivity of I. ricinus are based on the character of the local biocenosis of the respective region. The dynamics of its seasonal changes, conditioned by climatic factors, determines the annual differences. CONCLUSION: Three of the medically most important Borrelia species formed a core group among all detected genospecies. B. afzelii was a dominated one (115 detections), followed by B. garinii (100) and by B. burgdorferi s.s. (19). Other genospecies were detected sporadically. However, the detection of B. bissettii should be emphasized due to the recently proven pathogenic effects of this genospecies and yet little-known sporadic expansion in the Czech Republic. The medical importance and distribution of other sporadically occurred genospecies is also discussed.Key words: Ixodes ricinus - Borrelia afzelii - B. garinii - B. burgdorferi s. s. - B. bavariensis - B. valaisiana - B. spielmanii - B. lusitaniae - B. bissettii - distribution - altitude - season - medical importance. PMID- 27690477 TI - Campylobacteriosis in the South Bohemian Region - a Recurrent Problem. AB - AIM: Campylobacteriosis is among the most frequently reported foodborne diseases in both the Czech Republic (CR) and South Bohemian Region (SBR). Campylobacteriosis has been a notifiable disease in the CR since 1984. The objective of this study is the analysis of the data reported to the surveillance system between 2005 and 2014 to describe the seasonal variation, age specific incidence, and route of transmission of campylobacteriosis in the South Bohemian Region. MATERIAL AND METHODS: The data reported to the surveillance system EPIDAT from 2005 to 2014 were analysed in order to determine the incidence trends and seasonality, age distribution, and route of transmission of campylobacteriosis in the South Bohemian Region. RESULTS: Campylobacteriosis incidence in the South Bohemian Region follows the same annual pattern as in the Czech Republic. There is a very slight declining trend in the incidence over the study period. A strong seasonal variation was observed, with a late summer peak and a winter low. An exception to the regularity of the incidence pattern was an outbreak notified in 2010. The most affected age groups are children 1 to 5 years and newborns (0 age group). In the other age groups, the incidence has a declining tendency. The most common vehicles for the transmission of campylobacteriosis are chicken and meat products while other vehicles and routes of transmission have been reported exceptionally. CONCLUSION: Only one third of cases have been notified along with the suspected route of transmission. The most common route of transmission is through the consumption of contaminated chicken and meat, including smoked meat products. Therefore, the measures targeting consumers and also producers of poultry, meat, and unpasteurized milk products may contribute to the reduction of campylobacteriosis incidence.

PMID- 27690479 TI - Sleep quality affects cognitive functioning in returning combat veterans beyond combat exposure, PTSD, and mild TBI history. AB - OBJECTIVE: The purpose of this study was to determine how sleep quality affects cognitive functioning in returning combat veterans after accounting for effects of combat exposure, posttraumatic stress disorder (PTSD), and mild traumatic brain injury (mTBI) history. METHOD: This was a cross-sectional assessment study evaluating combat exposure, PTSD, mTBI history, sleep quality, and neuropsychological functioning. One hundred and nine eligible male Iraq/Afghanistan combat veterans completed an assessment consisting of a structured clinical interview, neuropsychological battery, and self-report measures. RESULTS: Using partial least squares structural equation modeling, combat experiences and mTBI history were not directly associated with sleep quality. PTSD was directly associated with sleep quality, which contributed to deficits in neuropsychological functioning independently of and in addition to combat experiences, PTSD, and mTBI history. Combat experiences and PTSD were differentially associated with motor speed. CONCLUSIONS: Sleep affected cognitive function independently of combat experiences, PTSD, and mTBI history. Sleep quality also contributed to cognitive deficits beyond effects of PTSD. An evaluation of sleep quality may be a useful point of clinical intervention in combat veterans with cognitive complaints. Improving sleep quality could alleviate cognitive complaints, improving veterans' ability to engage in treatment.

AB - Drawing from recent research advances indicating the harmful effects of insomnia on negative affect, job satisfaction, self-control, organizational citizenship behavior, and interpersonal deviance, we hypothesized that treating insomnia with Internet based cognitive behavior therapy for insomnia would lead to improvements in these outcomes. In a field experiment with a randomized wait-list control group, we found that treatment had a beneficial direct effect on negative affect, job satisfaction, and self-control. Moreover, the effect of treatment on job satisfaction was mediated by negative affect. We were not able to detect a direct effect of treatment on organizational citizenship behavior or interpersonal deviance. However, treatment had a beneficial indirect effect on organizational citizenship behavior through the mediators of negative affect and job satisfaction, and a beneficial indirect effect on interpersonal deviance through the mediator of self-control. These results move the applied psychology literature on insomnia beyond simply pointing out problematic effects of employee insomnia to providing evidence of a partial solution to such effects.

AB - Diabetes is a common, chronic, and costly condition that currently affects millions of individuals in the United States and worldwide with even greater numbers at high risk for developing the disease. Dramatic increases in diagnosed diabetes are projected for the decades to come meaning that most people will be affected by diabetes; either personally or through a family member. This article introduces the special issue of the American Psychologist focused on diabetes by providing an overview of the scope of diabetes and the importance of psychologists for improving disease management and quality of life. This includes an overview of the contributions of the behavioral and social sciences toward improved diabetes prevention and treatment. Finally, the article will point to opportunities for psychologists to close the gaps in the research, develop practice competencies, and increase training opportunities to meet the challenges of diabetes today and in the future. PMID- 27690482 TI - The social context of managing diabetes across the life span. AB - Diabetes self-management is crucial to maintaining quality of life and preventing long-term complications, and it occurs daily in the context of close interpersonal relationships. This article examines how social relationships are central to meeting the complex demands of managing Type I and Type 2 diabetes across the life span. The social context of diabetes management includes multiple resources, including family (parents, spouses), peers, romantic partners, and health care providers. We discuss how these social resources change across the life span, focusing on childhood and adolescence, emerging adulthood, and adulthood and aging. We review how diabetes both affects and is affected by key social relationships at each developmental period. Despite high variability in how the social context is conceptualized and measured across studies, findings converge on the characteristics of social relationships that facilitate or undermine diabetes management across the life span. These characteristics are consistent with both Interpersonal Theory and Self-Determination Theory, 2 organizing frameworks that we utilize to explore social behaviors that are related to diabetes management. Involvement and support from one's social partners, particularly family members, is consistently associated with good diabetes outcomes when characterized by warmth, collaboration, and acceptance. Underinvolvement and interactions characterized by conflict and criticism are consistently associated with poor diabetes outcomes. Intrusive involvement that contains elements of social control may undermine diabetes management, particularly when it impinges on self-efficacy. Implications for future research directions and for interventions that promote the effective use of the social context to improve diabetes self-management are discussed. (PsycINFO Database Record PMID- 27690485 TI - Neurocognitive consequences of diabetes. AB - Mild cognitive dysfunction is a well-established complication of diabetes and its management, although large numbers of psychologists and health professionals may be unaware of its existence, clinical implications, and etiology. Drawing on results from key studies, systematic reviews, and meta-analyses, this article delineates the neurocognitive phenotypes characteristic of Type 1 diabetes (T1D) and Type 2 diabetes (T2D), and identifies the most plausible risk factors, both those that may be modifiable, like degree of metabolic control, and those that cannot be changed, like the age when a child or adult is diagnosed. Most children and adults with T1D typically manifest lower scores on measures of intelligence and academic achievement, attention, psychomotor speed, and executive functions. These effects are especially pronounced in those who develop diabetes early in life, before the age of 6 or 7 years. Chronically elevated blood glucose values increase the risk of both cognitive dysfunction and microstructural changes in white matter tracts. Adults with T2D manifest cognitive dysfunction characterized by poorer performance on tasks requiring attention, psychomotor speed, planning and executive functions, and learning and memory. They are also at increased risk of developing dementia. Poorer metabolic control accelerates the rate of cognitive decline over time, and research suggests that improving metabolic control may slow the rate of decline. Psychologists and behavioral scientists can play a key role in preventing the onset of cognitive complications or in ameliorating their severity by implementing behavioral strategies known to increase adherence to medical regimens and improve metabolic control. (PsycINFO Database Record PMID- 27690483 TI - Psychosocial factors in medication adherence and diabetes self-management: Implications for research and practice. AB - Diabetes is a chronic illness that places a significant self-management burden on affected individuals and families. Given the importance of health behaviors-such as medication adherence, diet, physical activity, blood glucose self-monitoring in achieving optimal glycemic control in diabetes, interventions designed and delivered by psychologists hold promise in assisting children, adolescents, and adults with diabetes in improving their health status and lowering their risk of serious complications. This article first provides an overview of diabetes self management and associated challenges and burdens. Socioeconomic status factors that may influence diabetes management and outcomes are briefly highlighted. We then review the evidence base for select psychosocial factors that may be implicated in diabetes self-management. Modifiable targets of psychological intervention are presented across 3 overarching domains: (a) knowledge, beliefs, and related cognitive constructs; (b) emotional distress and well-being; and (c) behavioral skills and coping. Important methodological issues facing future research are discussed, along with opportunities for psychologists in improving the care and treatment outcomes of individuals and families living with diabetes. In conclusion, we advocate for continued research emphasis on improving psychosocial aspects of living with diabetes, with greater attention to the situational context in which the self-regulatory processes underlying self management occur. Psychologists have important roles to play in reducing emotional distress, improving patient knowledge, and providing training in behavioral skills to promote successful self-management and to support patient centered diabetes care. (PsycINFO Database Record PMID- 27690484 TI - Psychological conditions in adults with diabetes. AB - Type 1 (T1D) and Type 2 diabetes (T2D) represent a demanding set of biopsychosocial challenges for patients and their families, whether the age of disease onset occurs in childhood, adolescence, or adulthood. Psychological conditions, defined as syndromes, disorders, and diabetes-specific psychological issues affect a larger proportion of individuals with T1D and T2D compared to the general population. In this review, we summarize the prevalence, impact and psychological treatments associated with the primary categories of psychological conditions that affect adults with T1D and T2D: depressive symptoms and syndromes, anxiety disorders, eating behaviors and disorders and serious mental illness. The implications of the literature for psychologists are discussed, and priorities for future research to advance the science of psychological conditions for adults with T1D and T2D are identified. (PsycINFO Database Record PMID- 27690486 TI - Psychology, technology, and diabetes management. AB - Use of technology in diabetes management is rapidly advancing and has the potential to help individuals with diabetes achieve optimal glycemic control. Over the past 40 years, several devices have been developed and refined, including the blood glucose meter, insulin pump, and continuous glucose monitor. When used in tandem, the insulin pump and continuous glucose monitor have prompted the Artificial Pancreas initiative, aimed at developing control system for fully automating glucose monitoring and insulin delivery. In addition to devices, modern technology, such as the Internet and mobile phone applications, have been used to promote patient education, support, and intervention to address the behavioral and emotional challenges of diabetes management. These state-of the-art technologies not only have the potential to improve clinical outcomes, but there are possible psychological benefits, such as improved quality of life, as well. However, practical and psychosocial limitations related to advanced technology exist and, in the context of several technology-related theoretical frameworks, can influence patient adoption and continued use. It is essential for future diabetes technology research to address these barriers given that the clinical benefits appear to largely depend on patient engagement and consistence of technology use. (PsycINFO Database Record PMID- 27690488 TI - Behavior change to prevent or delay Type 2 diabetes: Psychology in action. AB - Self-management is critical for the prevention and control of chronic health conditions. Research shows that dietary and physical activity behaviors related to obesity are inextricably linked to the development, course, and outcomes of Type 2 diabetes and its comorbidities. Therefore, a compelling case has been made for behavioral lifestyle intervention as the first-line approach. Academic psychologists and other behavioral scientists have contributed to all stages of obesity and diabetes prevention research and practice. They have made seminal contributions to the evidence-based science of health behavior change with the National Institutes of Health funded Diabetes Prevention Program randomized clinical trial and subsequent translation and dissemination efforts as exemplars. Beginning with social-cognitive learning theory and behavior modification for obesity, research psychologists have elucidated the critical elements associated with treatment efficacy and have demonstrated the benefits of identifying individuals at elevated risk and providing early intervention. Most often, the psychologist's role has been to design and evaluate programs based on behavioral principles, or supervise, train, and facilitate adherence to interventions, rather than function as the primary provider. Lifestyle interventions have made a strong public health impact, but pressing challenges remain. Issues include difficulties with long-term weight loss maintenance, heterogeneity of treatment response, pragmatic translation and dissemination concerns such as optimal training and delivery formats, scalability of lifestyle intervention programs, reimbursement, and a need for environmental and policy approaches that promote healthy lifestyle norms and behaviors for all communities. Health psychology should be at the forefront in addressing all of these concerns.

AB - The majority of individuals with Type 2 diabetes (T2D) are overweight or obese, and this excess adiposity negatively impacts cardiovascular risk and contributes to challenges in disease management. Treatment of obesity by behavioral lifestyle intervention, within the context of diabetes, produces broad and clinically meaningful health improvements, and recent studies demonstrate long-term sustained weight management success with behavioral lifestyle interventions. Details of the Look AHEAD intensive lifestyle intervention are provided as an exemplar approach to the secondary prevention of T2D and obesity. The presence of behavior change expertise in the development and delivery of evidence-based behavioral weight control is discussed, and issues of adaptation and dissemination are raised, with a model to guide these important steps provided. (PsycINFO Database Record PMID- 27690487 TI - Evidence-based behavioral interventions to promote diabetes management in children, adolescents, and families. AB - As members of multidisciplinary diabetes care teams, psychologists are well suited to support self-management among youth with Type 1 diabetes (T1D) and Type 2 diabetes (T2D) and their families. Psychological and behavioral interventions can promote adherence to the complex and demanding diabetes care regimen, with the goals of promoting high quality of life, achieving optimal glycemic control, and ultimately preventing disease-related complications. This article reviews well-researched contemporary behavioral interventions to promote optimal diabetes family- and self-management and health outcomes in youth with T1D, in the context of key behavioral theories. The article summarizes the evidence base for established diabetes skills training programs, family interventions, and multisystemic interventions, and introduces emerging evidence for technology and mobile health interventions and health care delivery system interventions. Next steps in behavioral T1D intervention research include tailoring interventions to meet individuals' and families' unique needs and strengths, and systematically evaluating cost-effectiveness to advocate for dissemination of well-developed interventions. Although in its infancy, this article reviews observational and intervention research for youth with T2D and their families and discusses lessons for future research with this population. Interventions for youth with T2D will need to incorporate family members, consider cultural and family issues related to health behaviors, and take into account competing priorities for resources. As psychologists and behavioral scientists, we must advocate for the integration of behavioral health into routine pediatric diabetes care in order to effectively promote meaningful change in the behavioral and medical well-being of youth and families living with T1D and T2D. (PsycINFO Database Record PMID- 27690490 TI - Innovations in healthcare delivery and policy: Implications for the role of the psychologist in preventing and treating diabetes. AB - Although the biomedical model has dominated U.S. health care for more than a century, it has failed to adequately address current U.S. health care challenges, including the treatment and prevention of chronic disease; the epidemic rise in diabetes is one important example. In response, newer models of health care have been developed that address patients' mental and physical health concerns by multidisciplinary care teams that place the patient and family in the center of shared decision making. These new models of care offer many important opportunities for psychologists to play a larger role in the prevention and treatment of diabetes. However, for psychology's role to be fully realized, both external and internal challenges must be addressed. This will require psychologists to become more interdisciplinary, more familiar with the larger health care culture, more willing to expand their skill sets, and more collaborative with other health disciplines both from a patient-care and a larger advocacy perspective. (PsycINFO Database Record PMID- 27690491 TI - Phonological skills, visual attention span, and visual stress in developmental dyslexia. AB - In this study, we concurrently investigated 3 possible causes of dyslexia-a phonological deficit, visual stress, and a reduced visual attention span-in a large population of 164 dyslexic and 118 control French children, aged between 8 and 13 years old. We found that most dyslexic children showed a phonological deficit, either in terms of response accuracy (92.1% of the sample), speed (84.8%), or both (79.3%). Deficits in visual attention span, as measured by partial report ability, affected 28.1% of dyslexic participants, all of which also showed a phonological deficit. Visual stress, as measured by subjective reports of visual discomfort, affected 5.5% of dyslexic participants, not more than controls (8.5%). Although phonological variables explained a large amount of variance in literacy skills, visual variables did not explain any additional variance. Finally, children with comorbid phonological and visual deficits did not show more severe reading disability than children with a pure phonological deficit. These results (a) confirm the importance of phonological deficits in dyslexia; (b) suggest that visual attention span may play a role, but a minor one, at least in this population; (c) do not support any involvement of visual stress in dyslexia. Among the factors that may explain some differences with previously published studies, the present sample is characterized by very stringent inclusion criteria, in terms of the severity of reading disability and in terms of exclusion of comorbidities. This may exacerbate the role of phonological deficits to the detriment of other factors playing a role in reading acquisition. (PsycINFO Database Record PMID- 27690492 TI - Children's processing and comprehension of complex sentences containing temporal connectives: The influence of memory on the time course of accurate responses. AB - In a touch-screen paradigm, we recorded 3- to 7-year-olds' (N = 108) accuracy and response times (RTs) to assess their comprehension of 2-clause sentences containing before and after. Children were influenced by order: performance was most accurate when the presentation order of the 2 clauses matched the chronological order of events: "She drank the juice, before she walked in the park" (chronological order) versus "Before she walked in the park, she drank the juice" (reverse order). Differences in RTs for correct responses varied by sentence type: accurate responses were made more speedily for sentences that afforded an incremental processing of meaning. An independent measure of memory predicted this pattern of performance. We discuss these findings in relation to children's knowledge of connective meaning and the processing requirements of sentences containing temporal connectives. (PsycINFO Database Record PMID- 27690494 TI - "Life-span development of visual working memory: When is feature binding difficult?": Correction to Cowan et al. (2006). AB - Reports an error in "Life-span development of visual working memory: When is feature binding difficult?" by Nelson Cowan, Moshe Naveh-Benjamin, Angela Kilb and J. Scott Saults (Developmental Psychology, 2006[Nov], Vol 42[6], 1089-1102). In the article, there were two errors in experiment 1a. The mean for color item information in older adults was incorrectly calculated. As a result, Figure 3 shows a mean of over .70. The true mean was .63 (SEM=.04). This change diminishes the magnitude of the aging deficit for associative information, although this deficit still appears to remain, to a smaller extent. (For a conceptual replication see Peterson & Naveh-Benjamin, 2016). There also was an error in the experimental procedure of Experiment 1a. The older adults in that experiment received only half the number of trials specified in the methods section, and half as much as the other groups. For all groups, when there were 4 or 6 items and the probe was a binding change, the probed location was matched by the same color at 1 other location but, when there were 8 or 10 squares, the probed location was matched by the same color at 1, 2, or 3 other locations. For 8 squares the number of trials was identical for these three trial subtypes whereas, for 10 squares, most of the trials had the same color at just 1 other location. These errors suggest that the experiment should be taken as only preliminary evidence that there is an aging deficit in color-location binding in visual working memory when color and binding trials are mixed in the same trial blocks. (The following abstract of the original article appeared in record 2006 20488-009.) We asked whether the ability to keep in working memory the binding between a visual object and its spatial location changes with development across the life span more than memory for item information. Paired arrays of colored squares were identical or differed in the color of one square, and in the latter case, the changed color was unique on that trial (item change) or was duplicated elsewhere in the array (color-location binding change). Children (8-10 and 11-12 years old) and older adults (65-85 years old) showed deficits relative to young adults. These were only partly simulated by dividing attention in young adults. The older adults had an additional deficiency, specifically in binding information, which was evident only when item- and binding-change trials were mixed together. In that situation, the older adults often overlooked the more subtle, binding-type changes. Some working memory processes related to binding undergo life-span development in an inverted-U shape, whereas other, bias- and salience-related processes that influence the use of binding information seem to develop monotonically. PMID- 27690493 TI - Children's and adults' interpretation of covariation data: Does symmetry of variables matter? AB - In a series of 3 experiments, the authors investigated the influence of symmetry of variables on children's and adults' data interpretation. They hypothesized that symmetrical (i.e., present/present) variables would support correct interpretations more than asymmetrical (i.e., present/absent) variables. Participants were asked to judge covariation in a series of data sets presented in contingency tables and to justify their judgments. Participants in Experiments 1 and 2 were elementary school children (Experiment 1: n = 52 second graders, n = 44 fourth graders; Experiment 2: n = 50 second graders). Participants in Experiment 3 were adults (n = 62). In Experiment 1, children in the symmetrical variables condition performed better than those in the asymmetrical variables condition. Children in the symmetrical variables condition judged more data patterns correctly and they more frequently justified their choices by referring to the complete table. Experiment 2 ruled out the possibility that this effect was caused by differences in question format. Even when question format was held constant, second graders performed better with symmetrical variables. Experiment 3 showed that adults' data interpretation is also affected by symmetry of variables. Collectively, these results indicate that symmetry of variables affects interpretation of covariation data. The authors argue that symmetrical variables provide a context for meaningful comparison. With asymmetrical variables, the importance of the comparison is less salient. Thus, the symmetry of variables should be considered by researchers as well as educators. (PsycINFO Database Record PMID- 27690495 TI - Subjective and objective peer approval evaluations and self-esteem development: A test of reciprocal, prospective, and long-term effects. AB - A large body of literature suggests a clear, concurrent association between peer approval and self-esteem in adolescence. However, little empirical work exists on either the prospective or reciprocal relation between peer approval and self esteem during this age period. Moreover, it is unclear from past research whether both subjectively perceived peer approval and objectively measured peer approval are related to subsequent self-esteem over time (and vice versa) and whether these paths have long-term associations into adulthood. Using data from a large longitudinal study that covers a time span of 2 decades, we examined reciprocal, prospective relations between self-esteem and peer approval during ages 12-16 in addition to long-term relations between these variables and later social constructs at age 35. Cross-lagged regression analyses revealed small but persistent effect sizes from both types of peer approval to subsequent self esteem in adolescence, controlling for prior self-esteem. However, effects in the reverse direction were not confirmed. These findings support the notion that peer relationships serve an important function for later self-esteem, consistent with many theoretical tenets of the importance of peers for building a strong identity. Finally, we found long-term relations between adult social constructs and adolescent objective and subjective peer approval as well as self-esteem. Therefore, not only do peer relationships play a role in self-esteem development across adolescence, but they remain impactful throughout adulthood. In sum, the current findings highlight the lasting, yet small link between peer relationships and self-esteem development and call for investigations of further influential factors for self-esteem over time.

AB - Relations between early child care and adolescent functioning at the end of high school (EOHS; M age = 18.3 years) were examined in a prospective longitudinal study of 1,214 children. Controlling for extensive measures of family background, early child care was associated with academic standing and behavioral adjustment at the EOHS. More experience in center-type care was linked to higher class rank and admission to more selective colleges, and for females to less risk taking and greater impulse control. Higher quality child care predicted higher academic grades and admission to more selective colleges. Fewer hours in child care was related to admission to more selective colleges. These findings suggest long-term benefits of higher quality child care, center-type care, and lower child-care hours for measures of academic standing at the EOHS.

AB - We examined the mediational roles of multiple types of adolescents' emotional security in relations between multiple aspects of the interparental relationship and adolescents' mental health from ages 13 to 16 (N = 392). General marital quality, nonviolent parent conflict, and physical intimate partner violence independently predicted mental health. Security in the father-adolescent relationship, over and above security with the mother and security in regard to parent conflict, mediated the link from general marital quality to adolescents' mental health. With 2 exceptions, paths were stable for boys and girls, biological- and stepfathers, and Anglo- and Mexican Americans. The findings reveal the need to expand the traditional foci on parent conflict and relationships with mothers to include general marital quality and relationships with fathers.

(The following abstract of the original article appeared in record 2016-42727-001.) Over the last 20 years, the study of Temporal Psychology and its relationship with a range of psychosocial indicators has increased exponentially. The present study makes use of recent advances in analytic methods and uses statistical inference via longitudinal examination of latent profiles through Latent Transition Analyses (LTA). The first 2 available waves of data from a longitudinal study in the United Kingdom were used to assess the following: (a) the factor structure of Adolescent Time Inventory-Time Attitudes Scale (ATAS) scores at Waves 1 and 2, (b) the viability of time attitudes profiles based on ATAS scores at both time points, (c) the degree of stability and/or transition between membership of these profiles at +12 months, and (d) the relationship between profiles and scores on 4 distal outcomes, including academic, social and emotional self-efficacy, and sensation seeking. Four latent profiles called Positives, Ambivalents, Negatives, and Negative-Futures were identified and their relationship with the 4 distal outcomes was examined. Results showed that time attitude profiles were unstable across the first year of high school. Furthermore, instability was explained by transitions to more negative profiles, and these transitions were associated with unfavorable outcomes.

AB - The construct of positive family relationships (PFR), defined as family members getting along well and supporting each other, was investigated in a long-term prospective study. A newly constructed scale of positive family relationships developed using the nominal response model of item-response theory, was subject to a longitudinal network of relations analysis. The conceptualization for this research was founded on a positive psychology framework. Data derived from the Fullerton Longitudinal Study and spanned 20 years from middle childhood (age 9 years) to early adulthood (age 29 years). Evidence indicated both stability and change in PFR across time. Moderate to high stability of individual differences among families across 9 annual assessments was found from ages 9-17 years. Concomitantly across these years, there was a progressive decline in PFR. PFR proved to be independent of socioeconomic status. Specific conceptually based directional hypotheses were tested using structural equation modeling. Multiple sources of information included intra- and cross-informant, as well as objective and ecologically valid data. The network of relations involved concurrent and predictive criterion-related variables. PFR had a pervasive relation to a variety of psychological domains across time. As predicted, PFR related (a) positively to family cohesion and inversely to family conflict, (b) positively to parental social support, (c) positively to children's self-concept, (d) positively to children's academic performance and educational attainment, and (e) inversely to children's behavior problems. The theoretical importance of the findings and the applicability of the PFR Scale for both researchers and practitioners in the field of family psychology are discussed.

AB - Concerning the interdependence of married couples, the strengths of not only actors but also of partners might improve aging successfully. This study aimed to examine the actor and partner effects of resilience on well-being in Chinese older couples and the potential mediating role of spousal exchanges at the actor and partner levels. Using a 2-wave longitudinal design, a total of 158 Chinese couples (age range 60-97 years) completed measures of resilience, perceived spousal exchanges (spousal support and negative exchanges), and well-being. The results showed that (a) the dyad had significant congruence in resilience and well-being, respectively; (b) resilience had significant actor and partner effects on well-being within the dyad; and (c) negative spousal exchanges could not mediate the actor and partner effects of resilience on well-being, and a gender difference emerged for the mediation role of spousal support: Actor and partner effects of husbands' resilience on well-being were mediated by both partners' perceived spousal support, whereas the actor and partner effects of wives' resilience on well-being were not mediated by perceived spousal support. Focusing on couples' interdependence, this study highlighted the role of spousal resilience and support on successful aging. Interventions should focus on enhancing both partners' resilience and promoting mutual support within the couple.

AB - The present study tested the hypothesis that teens who engage in conduct problems are more likely to use substances because they engage in fewer alternative reinforcing (i.e., pleasurable) substance-free activities and more complementary reinforcing substance-associated activities. In a cross-sectional, correlational design, 9th grade students (N = 3,383; mean age = 14.6 years) in Los Angeles, California, U.S.A. completed surveys in 2013 measuring conduct problems (e.g., stealing, lying, getting in fights); alternative and complementary reinforcement; use of a number of licit, illicit, and prescription drugs; and other cofactors. Conduct problems were positively associated with past 6-month use of any substance (yes/no) among the overall sample and past 30-day use frequency on a composite index that included 6 substances among past 6-month users. These associations were statistically mediated by diminished alternative reinforcement and increased complementary reinforcement when adjusting for relevant covariates. Conduct problems were associated with lower engagement in alternative reinforcers and increased engagement in complementary reinforcers, which, in turn, were associated with greater likelihood and frequency of substance use. Most mediational relations persisted adjusting for demographic, environmental, and intrapersonal cofactors and generalized to alcohol, cigarette, and marijuana use, although, complementary reinforcers did not significantly mediate the relation of conduct problems with alcohol use frequency. These results point to diminished alternative reinforcement and increased complementary reinforcement as mechanisms linking conduct problems and adolescent substance use. Interventions that increase access to and engagement in a diverse set of alternative substance-free activities and deter activities that complement use may prevent substance use in adolescents who engage in conduct problems.

AB - Recent clinical and preclinical research has suggested that cannabidiol (CBD) and Delta9-tetrahydrocannabinol (Delta9-THC) have interactive effects on measures of cognition; however, the nature of these interactions is not yet fully characterized. To address this, we investigated the effects of Delta9-THC and CBD independently and in combination with proposed therapeutic dose ratios of 1:1 and 1:3 Delta9-THC:CBD in adult rhesus monkeys (n = 6) performing a stop signal task (SST). Additionally, the development of tolerance to the effects of Delta9-THC on SST performance was evaluated by determining the effects of acutely administered Delta9-THC (0.1-3.2 mg/kg), during a 24-day chronic Delta9-THC treatment period with Delta9-THC alone or in combination with CBD. Results indicate that Delta9 THC (0.032-0.32 mg/kg) dose-dependently decreased go success but did not alter go reaction time (RT) or stop signal RT (SSRT); CBD (0.1-1.0 mg/kg) was without effect on all measures and, when coadministered in a 1:1 dose ratio, did not exacerbate or attenuate the effects of Delta9-THC. When coadministered in a 1:3 dose ratio, CBD (1.0 mg/kg) attenuated the disruptive effects of 0.32 mg/kg Delta9-THC but did not alter the effects of other Delta9-THC doses. Increases in ED50 values for the effects of Delta9-THC on SST performance were apparent during chronic Delta9-THC treatment, with little evidence for modification of changes in sensitivity by CBD. These results indicate that CBD, when combined with Delta9 THC in clinically available dose ratios, does not exacerbate and, under restricted conditions may even attenuate, Delta9-THC's behavioral effects. (PsycINFO Database Record PMID- 27690504 TI - The role of past interactions in great apes' communication about absent entities. AB - Recent evidence suggests that great apes can use the former location of an entity to communicate about it. In this study we built on these findings to investigate the social-cognitive foundations of great apes' communicative abilities. We tested whether great apes (n = 35) would adjust their requests for absent entities to previous interactions they had with their interlocutor. We manipulated the apes' experience with respect to the interlocutor's knowledge about the previous content of the now-empty location as well as their experience with the interlocutor's competence to provide additional food items. We found that apes adjusted their requests to both of these aspects but failed to integrate them with one another. These results demonstrate a surprising amount of flexibility in great apes' communicative abilities while at the same time suggesting some important limitations in their social communicative skills. (PsycINFO Database Record PMID- 27690503 TI - Use of an automated mobile application to assess effects of nicotine withdrawal on verbal fluency: A pilot study. AB - Mild-to-moderate impairment in frontally mediated functions such as sustained attention, working memory, and inhibition have been found to occur during tobacco withdrawal and may present a barrier to successful cessation. These findings have led to studies evaluating cessation treatments that target nicotine withdrawal related cognitive impairment. The instruments currently used to assess cognitive function provide detailed and specific information but have limitations including being time consuming, cumbersome, anxiety provoking, and having poor ecological validity. The authors examined the feasibility of using a mobile computer application to test verbal fluency (VF) as a quick, easy-to-administer, and more ecologically valid method of measuring the effects of short-term smoking abstinence on frontally mediated cognitive functions. Thirty participants completed 2 assessments-1 during ad lib smoking and 1 after overnight abstinence. At each assessment, semantic and phonemic VF tests were administered using a mobile application and nicotine craving and withdrawal symptom severity was assessed. In repeated assessments, performance on both semantic and phonemic VF tests is expected to improve due to practice effects; however, significant improvements were observed only in semantic (p = .012) but not phonemic (p = .154) VF. In addition, the change between assessments in phonemic (but not semantic) score was significantly associated with withdrawal (p = .006) and craving (p = .037) severity measured postabstinence. This study demonstrates that nicotine withdrawal has differential effects on semantic versus phonemic VF suggesting impairments of working memory, attention, and inhibition. These effects were measured using methods easily used in large groups of participants, potentially with remote test administration and automated scoring. (PsycINFO Database Record PMID- 27690505 TI - Daily relations among affect, urge, targeted naltrexone, and alcohol use in young adults. AB - Heavy drinking among young adults is a serious public health problem. Naltrexone, an opioid antagonist, has been shown to reduce drinking in young adults compared to placebo and can be taken on a targeted (i.e., as needed) basis. Understanding risk factors for drinking and naltrexone effects within-person in young adults may help to optimize the use of targeted naltrexone. The current study was a secondary analysis of daily diary data from 127 (n = 40 female) young adults (age 18-25) enrolled in a double-blind clinical trial of daily (25 mg) plus targeted (25 mg) naltrexone versus placebo. Hierarchical linear models were used to examine the effects of daily affect, urge, and taking targeted medication on same day risk of drinking to intoxication (defined as estimated blood-alcohol concentration, BAC >= .08 g%). Results indicated urge significantly mediated within-person positive affect-drinking relations on a daily level. Specifically, positive affect was associated with greater urge to drink, which in turn was associated with greater odds of BAC >= .08 g%. Furthermore, days of greater positive affect and urge were associated with taking a targeted dose of medication, which reduced the likelihood of intoxication by nearly 23% in the naltrexone group compared to placebo. Gender and family history of alcohol dependence were examined as moderators of these daily level effects. These results provide further evidence of naltrexone's ability to reduce alcohol consumption in young adults and identify potential within-person risk processes related to heavy drinking that could inform alcohol-related interventions for this population. (PsycINFO Database Record PMID- 27690506 TI - Initial feasibility and validity of a prospective memory training program in a substance use treatment population. AB - Individuals with substance use disorders have shown deficits in the ability to implement future intentions, called prospective memory. Deficits in prospective memory and working memory, a critical underlying component of prospective memory, likely contribute to substance use treatment failures. Thus, improvement of prospective memory and working memory in substance use patients is an innovative target for intervention. We sought to develop a feasible and valid prospective memory training program that incorporates working memory training and may serve as a useful adjunct to substance use disorder treatment. We administered a single session of the novel prospective memory and working memory training program to participants (n = 22; 13 men, 9 women) enrolled in outpatient substance use disorder treatment and correlated performance to existing measures of prospective memory and working memory. Generally accurate prospective memory performance in a single session suggests feasibility in a substance use treatment population. However, training difficulty should be increased to avoid ceiling effects across repeated sessions. Consistent with existing literature, we observed superior performance on event-based relative to time-based prospective memory tasks. Performance on the prospective memory and working memory training components correlated with validated assessments of prospective memory and working memory, respectively. Correlations between novel memory training program performance and established measures suggest that our training engages appropriate cognitive processes. Further, differential event- and time-based prospective memory task performance suggests internal validity of our training. These data support the development of this intervention as an adjunctive therapy for substance use disorders. (PsycINFO Database Record PMID- 27690508 TI - Emotion and decision-making under uncertainty: Physiological arousal predicts increased gambling during ambiguity but not risk. AB - Uncertainty, which is ubiquitous in decision-making, can be fractionated into known probabilities (risk) and unknown probabilities (ambiguity). Although research has illustrated that individuals more often avoid decisions associated with ambiguity compared to risk, it remains unclear why ambiguity is perceived as more aversive. Here we examine the role of arousal in shaping the representation of value and subsequent choice under risky and ambiguous decisions. To investigate the relationship between arousal and decisions of uncertainty, we measure skin conductance response-a quantifiable measure reflecting sympathetic nervous system arousal-during choices to gamble under risk and ambiguity. To quantify the discrete influences of risk and ambiguity sensitivity and the subjective value of each option under consideration, we model fluctuating uncertainty, as well as the amount of money that can be gained by taking the gamble. Results reveal that although arousal tracks the subjective value of a lottery regardless of uncertainty type, arousal differentially contributes to the computation of value-that is, choice-depending on whether the uncertainty is risky or ambiguous: Enhanced arousal adaptively decreases risk-taking only when the lottery is highly risky but increases risk-taking when the probability of winning is ambiguous (even after controlling for subjective value). Together, this suggests that the role of arousal during decisions of uncertainty is modulatory and highly dependent on the context in which the decision is framed. (PsycINFO Database Record PMID- 27690509 TI - Replicable effects of primes on human behavior. AB - [Correction Notice: An Erratum for this article was reported online in Journal of Experimental Psychology: General on Oct 31 2016 (see record 2016-52334-001). ] The effect of primes (i.e., incidental cues) on human behavior has become controversial. Early studies reported counterintuitive findings, suggesting that primes can shape a wide range of human behaviors. Recently, several studies failed to replicate some earlier priming results, raising doubts about the reliability of those effects. We present a within-subjects procedure for priming behavior, in which participants decide whether to bet or pass on each trial of a gambling game. We report 6 replications (N = 988) showing that primes consistently affected gambling decisions when the decision was uncertain. Decisions were influenced by primes presented visibly, with a warning to ignore the primes (Experiments 1 through 3) and with subliminally presented masked primes (Experiment 4). Using a process dissociation procedure, we found evidence that primes influenced responses through both automatic and controlled processes (Experiments 5 and 6). Results provide evidence that primes can reliably affect behavior, under at least some conditions, without intention. The findings suggest that the psychological question of whether behavior priming effects are real should be separated from methodological issues affecting how easily particular experimental designs will replicate. PMID- 27690507 TI - Prescription stimulant medication misuse: Where are we and where do we go from here? AB - Prescription stimulants, including methylphenidate (e.g., Ritalin) and amphetamine compounds (e.g., dextroamphetamine; Adderall), have been approved by the U.S. Food and Drug Administration for the treatment of attention deficit/hyperactivity disorder (ADHD) and are classified by the United States Drug Enforcement Administration as Schedule II medications because of their high potential for abuse and dependence (Drug Enforcement Administration, U.S. Department of Justice, 2015). Despite the potential health and judicial consequences, misuse of prescription stimulants, typically defined as taking stimulants without a valid prescription, or use of stimulants other than as prescribed, has become a serious problem in the United States and abroad, especially on college campuses. The purpose of the present article is to review historical information concerning prescription stimulants and to summarize the literature with respect to misuse among adults, particularly college students, including risk factors, mediators and moderators, and motivations for prescription stimulant misuse. In addition, evidence is presented concerning the question of whether prescription stimulants truly enhance cognitive functioning in individuals with and without ADHD, and the ethical and professional implications of these findings are explored. Lastly, recommendations for addressing prescription stimulant misuse and suggestions for future research are advanced. (PsycINFO Database Record PMID- 27690510 TI - An integrated perspective on insight. AB - The present study on insight is based on an integration of Kaplan and Simon's (1990) information processing theory of insight, a cognitive style theory, and achievement motivation theory. The style theory is the Assimilator (rule oriented, familiarity seeking)-Explorer (novelty seeking, explorative) styles (Kaufmann, 1979). Our hypothesis is that the effectiveness of 2 types of search constraints (prior experience and solution hints) for solving insight problems is moderated by both cognitive style and achievement needs, and depending on optimal levels of achievement motivation for different task conditions. We tested the hypothesis in a randomized experiment in which 3 levels of achievement needs and 1 type of search constraint (solution hints were available or not available) were experimentally manipulated. In addition, participants completed a cognitive style test, a measure of prior problem-solving experience (the second type of search constraint), and controls for intelligence. There were 476 participants (the mean age was 18.4 years). Results revealed 2 similar and significant 3-way interactions between styles, achievement needs, and the 2 types of search constraints. The pattern of interaction supported the idea that stylistic competence for the task characteristics (with and without search constraints available), when combined with manipulated achievement needs, predicted performance in counterintuitive ways but in line with the classic achievement motivation theory. With appropriate stylistic competence for the task characteristics elevated achievement needs led to poorer performance. With less appropriate stylistic competence, performance improved with increasing motivation. Implications for information processing theory are discussed.

(2016). AB - Reports an error in "A general benevolence dimension that links neural, psychological, economic, and life-span data on altruistic tendencies" by Jason Hubbard, William T. Harbaugh, Sanjay Srivastava, David Degras and Ulrich Mayr (Journal of Experimental Psychology: General, Advanced Online Publication, Aug 11, 2016, np). In the article, there was an error in the Task, Stimuli, and Procedures section. In the 1st sentence in the 6th paragraph, "Following the scanning phase, participants completed self-report questionnaires meant to reflected the Prosocial Disposition construct: the agreeableness scale from the Big F, which includes empathic concern and perspective-taking, and a scale of personality descriptive adjectives related to altruistic behavior (Wood, Nye, & Saucier, 2010)." should have read: "Following the scanning phase, participants completed self-report questionnaires that contained scales to reflect the Prosocial Disposition construct: the Big Five Inventory (BFI; John et al., 1991), from which we used the agreeableness scale to measure prosocial disposition; the Interpersonal Reactivity Index (IRI; Davis, 1980), from which we used the empathic concern and perspective-taking scales; and a scale of personality descriptive adjectives related to altruistic behavior (Wood, Nye, & Saucier, 2010)." (The following abstract of the original article appeared in record 2016 39037-001.) Individual and life span differences in charitable giving are an important economic force, yet the underlying motives are not well understood. In an adult, life span sample, we assessed manifestations of prosocial tendencies across 3 different measurement domains: (a) psychological self-report measures, (b) actual giving choices, and (c) fMRI-derived, neural indicators of "pure altruism." The latter expressed individuals' activity in neural valuation areas when charities received money compared to when oneself received money and thus reflected an altruistic concern for others. Results based both on structural equation modeling and unit-weighted aggregate scores revealed a strong higher order General Benevolence dimension that accounted for variability across all measurement domains. The fact that the neural measures likely reflect pure altruistic tendencies indicates that General Benevolence is based on a genuine concern for others. Furthermore, General Benevolence exhibited a robust increase across the adult life span, potentially providing an explanation for why older adults typically contribute more to the public good than young adults. PMID- 27690512 TI - Distractibility is a function of engagement, not task difficulty: Evidence from a new oculomotor capture paradigm. AB - It has been shown that when humans require a brief moment of concentration or mental effort, they tend to avert their gaze away from the attended location (or even blink). Similarly, participants tend to miss unexpected events when they are highly focused on a task. We present an engagement theory of distractibility that is meant to capture the relationship between participants' engagement in a task and reduction in sensitivity to new sensory events in a broad range of situations. In a series of experiments, we asked participants to perform different cognitive tasks of varying degrees of difficulty while we measured spontaneous oculomotor capture by new images that were completely unrelated to the participants' task. The images appeared while participants were cognitively engaged in the task. Our results showed that increased cognitive engagement produced decreased sensitivity to visual events. We propose that individual differences in intrinsic motivation play a large role in determining sensitivity to task unrelated events. In addition, our results also indicate that changes in task difficulty on a trial-to-trial basis do not generate trial-by-trial differences in oculomotor capture. Importantly, we believe our framework provides us with a promising way of extending laboratory findings to many real world situations.

Comment on Foroughi, Werner, Barragan, and Boehm-Davis (2015). AB - In a recent article, Foroughi, Werner, Barragan, and Boehm-Davis (2015) demonstrated that interspersing interruptions between paragraphs during reading sometimes reduces accuracy on comprehension questions. We propose an account of their findings within long-term working memory (LTWM) theory. Our account proposes that interruptions interfere with the accessibility of the generated encodings of the text in long-term memory (LTM) and that unimpaired continued comprehension requires restoration of access to these memory encodings during the resumption of reading after the interruptions. It is consistent with the accuracy of question answering being substantially preserved in their study, which is seemingly inconsistent with their transient storage account. This theoretical controversy does not diminish the importance of Foroughi et al.'s results: We agree that additional research is needed to understand when and how interruptions impact various aspects of comprehension. (PsycINFO Database Record PMID- 27690514 TI - Multiple interpretations of long-term working memory theory: Reply to Delaney and Ericsson (2016). AB - This reply is in response to Delaney and Ericsson (2016), who argue that the results of our recent research (Foroughi, Werner, Barragan, & Boehm-Davis, 2015) can be explained by Ericsson and Kintsch's (1995) long-term working memory (LTWM) theory. Our original work was designed to test the prediction made by LTWM theory that interruptions of up to 30 s in duration would not disrupt reading performance. We conducted the work following the method and outcome measures recommended by Ericsson and Kintsch (1995). Our data were clear: interruptions disrupted reading comprehension. We believe that these data do not support predictions made by LTWM theory. Although we appreciate Delaney and Ericsson's (2016) comments, we are unsure how best to move forward because it appears that some of their comments are not consistent with the published work on LTWM theory. Because of the inconsistent and contradictory claims surrounding LTWM theory, the theory does not appear to be falsifiable, or is in danger of becoming unfalsifiable. Creating and testing theory is vital for the advancement of psychological science, but it appears that testing predictions made by LTWM would be very difficult, if not impossible, given the fluid state of the theory. (PsycINFO Database Record PMID- 27690515 TI - The roles of perceptual and conceptual information in face recognition. AB - The representation of familiar objects is comprised of perceptual information about their visual properties as well as the conceptual knowledge that we have about them. What is the relative contribution of perceptual and conceptual information to object recognition? Here, we examined this question by designing a face familiarization protocol during which participants were either exposed to rich perceptual information (viewing each face in different angles and illuminations) or with conceptual information (associating each face with a different name). Both conditions were compared with single-view faces presented with no labels. Recognition was tested on new images of the same identities to assess whether learning generated a view-invariant representation. Results showed better recognition of novel images of the learned identities following association of a face with a name label, but no enhancement following exposure to multiple face views. Whereas these findings may be consistent with the role of category learning in object recognition, face recognition was better for labeled faces only when faces were associated with person-related labels (name, occupation), but not with person-unrelated labels (object names or symbols). These findings suggest that association of meaningful conceptual information with an image shifts its representation from an image-based percept to a view invariant concept. They further indicate that the role of conceptual information should be considered to account for the superior recognition that we have for familiar faces and objects. (PsycINFO Database Record PMID- 27690516 TI - Off the rails in rural South Carolina: a qualitative study of healthcare provider perspectives on the long-term health impact of the Graniteville train disaster. AB - INTRODUCTION: In 2005, a train derailment and subsequent chlorine spill ravaged the rural town of Graniteville in South Carolina, resulting in one of the worst chlorine gas exposures in US. HISTORY: Significant health and economic challenges persist in the community more than a decade later. Healthcare providers offered healthcare services to community members in the immediate aftermath of the disaster, and many still live in the community and continue to provide healthcare services. As such, healthcare professionals provide a unique and important perspective to help understand the impact of the disaster on the community's health. The purpose of this study was to explore healthcare providers' perspectives about the long-term effects of the disaster on community health, healthcare access, and wellbeing. METHODS: Semi-structured interviews were conducted with 30 healthcare providers who treated survivors of the Graniteville train disaster. A qualitative, essentialist, inductive thematic analytic approach was used to analyze study data. RESULTS: Four themes emerged regarding the disaster's long-term impact: effects of chlorine exposure on physical health, issues with healthcare access, residual effects of the disaster on personal and community wellbeing, and improving health and community wellbeing. CONCLUSIONS: Disaster recovery should not be considered solely an acute event; agencies must be prepared for long-term, potentially chronic ailments, particularly in underserved, rural communities. Efforts to address the long-term health needs of communities post-disaster should consider the perspectives of healthcare providers to offer a well-rounded assessment of community needs. Study findings can help inform future disaster response strategies in communities locally and globally. PMID- 27690518 TI - You Seldom Get a Second Chance With a Gunshot: Lethality of Suicidal Acts. PMID- 27690517 TI - The Risk of Treatment-Emergent Mania With Methylphenidate in Bipolar Disorder. AB - OBJECTIVE: The authors sought to determine the risk of treatment-emergent mania associated with methylphenidate, used in monotherapy or with a concomitant mood stabilizing medication, in patients with bipolar disorder. METHOD: Using linked Swedish national registries, the authors identified 2,307 adults with bipolar disorder who initiated therapy with methylphenidate between 2006 and 2014. The cohort was divided into two groups: those with and those without concomitant mood stabilizing treatment. To adjust for individual-specific confounders, including disorder severity, genetic makeup, and early environmental factors, Cox regression analyses were used, conditioning on individual to compare the rate of mania (defined as hospitalization for mania or a new dispensation of stabilizing medication) 0-3 months and 3-6 months after medication start following nontreated periods. RESULTS: Patients on methylphenidate monotherapy displayed an increased rate of manic episodes within 3 months of medication initiation (hazard ratio=6.7, 95% CI=2.0-22.4), with similar results for the subsequent 3 months. By contrast, for patients taking mood stabilizers, the risk of mania was lower after starting methylphenidate (hazard ratio=0.6, 95% CI=0.4-0.9). Comparable results were observed when only hospitalizations for mania were counted. CONCLUSIONS: No evidence was found for a positive association between methylphenidate and treatment-emergent mania among patients with bipolar disorder who were concomitantly receiving a mood-stabilizing medication. This is clinically important given that up to 20% of people with bipolar disorder suffer from comorbid ADHD. Given the markedly increased hazard ratio of mania following methylphenidate initiation in bipolar patients not taking mood stabilizers, careful assessment to rule out bipolar disorder is indicated before initiating monotherapy with psychostimulants. PMID- 27690519 TI - Broad- versus Narrow-Spectrum Oral Antibiotic Transition and Outcomes in Health Care-associated Pneumonia. AB - RATIONALE: Guidelines recommend a switch from intravenous to oral antibiotics once patients who are hospitalized with pneumonia achieve clinical stability. However, little evidence guides the selection of an oral antibiotic for patients with health care-associated pneumonia, especially where no microbiological diagnosis is made. OBJECTIVES: To compare outcomes between patients who were transitioned to broad- versus narrow-spectrum oral antibiotics after initially receiving broad-spectrum intravenous antibiotic coverage. METHODS: We performed a secondary analysis of an existing database of adults with community-onset pneumonia admitted to seven Utah hospitals. We identified 220 inpatients with microbiology-negative health care-associated pneumonia from 2010 to 2012. After excluding inpatient deaths and treatment failures, 173 patients remained in which broad-spectrum intravenous antibiotics were transitioned to an oral regimen. We classified oral regimens as broad-spectrum (fluoroquinolone) versus narrow spectrum (usually a beta-lactam). We compared demographic and clinical characteristics between groups. Using a multivariable regression model, we adjusted outcomes by severity (electronically calculated CURB-65), comorbidity (Charlson Index), time to clinical stability, and length of intravenous therapy. MEASUREMENTS AND MAIN RESULTS: Age, severity, comorbidity, length of intravenous therapy, and clinical response were similar between the two groups. Observed 30 day readmission (11.9 vs. 21.4%; P = 0.26) and 30-day all-cause mortality (2.3 vs. 5.3%; P = 0.68) were also similar between the narrow and broad oral antibiotic groups. In multivariable analysis, we found no statistically significant differences for adjusted odds of 30-day readmission (adjusted odds ratio, 0.56; 95% confidence interval, 0.06-5.2; P = 0.61) or 30-day all-cause mortality (adjusted odds ratio, 0.55; 95% confidence interval, 0.19-1.6; P = 0.26) between narrow and broad oral antibiotic groups. CONCLUSIONS: On the basis of analysis of a limited number of patients observed retrospectively, our findings suggest that it may be safe to switch from broad-spectrum intravenous antibiotic coverage to a narrow-spectrum oral antibiotic once clinical stability is achieved for hospitalized patients with health care-associated pneumonia when no microbiological diagnosis is made. A larger retrospective study with propensity matching or regression-adjusted test of equivalence or ideally a prospective comparative effectiveness study will be necessary to confirm our observations.

AB - BACKGROUND: The optimal anticoagulation strategy for venovenous extracorporeal membrane oxygenation (VV-ECMO) is not known. OBJECTIVES: To evaluate the safety of anticoagulation strategies and monitoring during VV-ECMO for respiratory failure. DATA SOURCES: We conducted a systematic review to evaluate the association between anticoagulation strategies during VV-ECMO and prespecified outcomes, including major bleeding episodes, thrombotic events, and in-hospital mortality. We included articles published between 1977 and January 30, 2015. Study quality was assessed using the Newcastle-Ottawa scoring system. A separate meta-analysis was not planned. DATA EXTRACTION: Data were independently extracted by two authors and collected on a standardized report form. SYNTHESIS: A total of 18 studies (n = 646) were included; 17 studies enrolled patients with acute respiratory distress syndrome. Across all studies, the duration of VV-ECMO support ranged from 4 to 20 days. Patients received an average of 2.3 (+/-3.9) units of transfused red blood cells per day. The bleeding rate across all studies was 16%, and the rate of thrombosis was 53%. Among seven studies (199 patients) targeting a specified activated partial thromboplastin time (aPTT), there were 37 (19%) major bleeding episodes and 53 (27%) major thromboses. Among five studies (43 patients) with aPTT targets of 60 seconds or greater, there were 24 (56%) bleeding episodes and 3 (7%) clotting events. Three studies (156 patients) with an aPTT target under 60 seconds reported 13 (8%) and 50 (32%) significant bleeding and thrombotic events, respectively. The most commonly reported thrombotic events were circuit-related clotting and deep-vein thrombosis. Mortality during VV-ECMO varied across the studies, ranging from 0 to at least 50% at heterogeneous time points. The total number of deaths for all studies combined was 186 (29%). CONCLUSIONS: The role and optimal therapeutic targets for anticoagulation during VV-ECMO are unclear. Previously published studies are limited by retrospective, observational design, small cohorts, and patient heterogeneity. The clinical significance of reported thrombotic complications is largely unknown. This systematic review underscores the need for randomized controlled trials of anticoagulation strategies for patients undergoing VV-ECMO for respiratory failure. PMID- 27690528 TI - Intrinsic Foot Muscle Activation During Specific Exercises: A T2 Time Magnetic Resonance Imaging Study. AB - CONTEXT: The intrinsic foot muscles maintain the medial longitudinal arch and aid in force distribution and postural control during gait. Impaired intrinsic foot muscle function has been linked to various foot conditions. Several rehabilitative exercises have been proposed to improve it; however, literature that identifies which individual muscles are activated during specific intrinsic foot-muscle exercises is lacking. OBJECTIVE: To describe changes in activation of the intrinsic plantar foot muscles after 4 exercises as measured with T2 magnetic resonance imaging (MRI). DESIGN: Descriptive laboratory study. SETTING: Research laboratory. PATIENTS OR OTHER PARTICIPANTS: Eight healthy National Collegiate Athletic Association Division I collegiate cross-country and track athletes (5 men and 3 women: age = 20 +/- 0.93 years, height = 180.98 +/- 10.84 cm, mass = 70.91 +/- 7.82 kg). INTERVENTION(S): Participants underwent T2 MRI before and after each exercise. They completed 1 set of 40 repetitions of each exercise (short-foot exercise, toes spread out, first-toe extension, second- to fifth-toes extension). MAIN OUTCOME MEASURE(S): Percentage increases in muscle activation of the abductor hallucis, flexor digitorum brevis, abductor digiti minimi, quadratus plantae, flexor digiti minimi, adductor hallucis oblique, flexor hallucis brevis, and interossei and lumbricals (analyzed together) after each exercise were assessed using T2 MRI. RESULTS: All muscles showed increased activation after all exercises. The mean percentage increase in activation ranged from 16.7% to 34.9% for the short-foot exercise, 17.3% to 35.2% for toes spread out, 13.1% to 18.1% for first-toe extension, and 8.9% to 22.5% for second- to fifth-toes extension. All increases in activation had associated 95% confidence intervals that did not cross zero. CONCLUSIONS: Each of the 4 exercises was associated with increased activation in all of the plantar intrinsic foot muscles evaluated. These results may have clinical implications for the prescription of specific exercises to target individual intrinsic foot muscles. PMID- 27690530 TI - Introduction. PMID- 27690531 TI - Premature Ovarian Insufficiency: New Perspectives on Genetic Cause and Phenotypic Spectrum. AB - Premature ovarian insufficiency (POI) is one form of female infertility, defined by loss of ovarian activity before the age of 40 and characterized by amenorrhea (primary or secondary) with raised gonadotropins and low estradiol. POI affects up to one in 100 females, including one in 1000 before the age of 30. Substantial evidence suggests a genetic basis for POI; however, the majority of cases remain unexplained, indicating that genes likely to be associated with this condition are yet to be discovered. This review discusses the current knowledge of the genetic basis of POI. We highlight genes typically known to cause syndromic POI that can be responsible for isolated POI. The role of mouse models in understanding POI pathogenesis is discussed, and a thorough list of candidate POI genes is provided. Identifying a genetic basis for POI has multiple advantages, such as enabling the identification of presymptomatic family members who can be offered counseling and cryopreservation of eggs before depletion, enabling personalized treatment based on the cause of an individual's condition, and providing better understanding of disease mechanisms that ultimately aid the development of improved treatments. PMID- 27690529 TI - Association of Physical Inactivity, Weight, Smoking, and Prior Injury on Physical Performance in a Military Setting. AB - CONTEXT: Although inactivity, being overweight, smoking, and a history of injury are identified as risk factors for poor health and injury, few authors have examined their association on physical performance. Young adults may be more likely to adopt healthier lifestyles if they understand the effect of health behaviors on performance. OBJECTIVE: To determine the association of being overweight, smoking, inactivity, and a history of injury with physical performance. DESIGN: Cross-sectional study. SETTING: Military population. PATIENTS OR OTHER PARTICIPANTS: Active-duty service members (N = 1466; 1380 men, 86 women; age = 24.7 +/- 5.0 years; body mass index = 26.7 +/- 3.4 kg/m2). MAIN OUTCOME MEASURE(S): Participants performed 8 measures (the triple-crossover hop for distance, the 6-m timed-hop test, the Functional Movement Screen, the Lower Quarter Y-Balance Test, the Upper Quarter Y-Balance Test, and the 3-event Army Physical Fitness Test) for evaluation of endurance, strength, muscular endurance, power, agility, balance, and motor control. Participants were categorized based on the number of health risk factors present. Using an analysis of covariance, we assessed the relationship between risk factors and physical performance with age and sex as covariates. RESULTS: Compared with those who had no risk factors (27.9% of men, 34.9% of women), physical performance was worse in those who had 1, 2, or 3 to 4 risk factors present by 4.3%, 6.7%, and 10.3%, respectively. Decrements in performance for those with 3 to 4 risk factors ranged from 3.3% to 14.4%. CONCLUSIONS: An unhealthy lifestyle habit or a history of injury was negatively associated with physical performance. Physical performance decrements were associated with the number of risk factors present. Understanding how risk factors contribute to decreased physical performance may enable clinicians to improve compliance with injury-prevention programs in occupational settings in which a young and relatively healthy workforce may be more concerned about performance than health.

PMID- 27690538 TI - Role of diffusion weighted magnetic resonance imaging in a rat model of testicular torsion. AB - OBJECTIVE: The purpose of this study was to investigate the usefulness of diffusion-weighted imaging (DWI) in the detection of different degrees of testicular torsion (TT) at the 8th hour and testicular salvageability at the 24th hour of torsion. METHODS: 31 rats were randomly classified into 4 groups. In Group 1 (sham-control group), the left testicle was kept outside and replaced. Left testicles were kept outside and twisted 360 degrees in Group 2, 720 degrees in Group 3 and 1080 degrees in Group 4. Later, DWI was performed at 8th and 24th hours. After DWI, bilateral radical orchiectomy and histopathological examination were performed. Apparent diffusion coefficient (ADC) maps were obtained with b-factors of 0 and 800 s mm-2. Comparisons of ADC values and damage in testicles were performed with Kruskal-Wallis test. RESULTS: Sensitivity of DWI in the diagnosis of TT was 12.5% for 360 degrees torsion, 100% for 720 degrees torsion and 1080 degrees torsion at the 8th hour of torsion. Mean ADC values of the left testicles increased significantly at the 24th hour of torsion in Groups 3 and 4. All testicles in Groups 3 and 4 were observed to be irrecoverable on histopathological examination. CONCLUSION: Increased ADC values in the affected testicle may represent irreversible tissue damage. So, immediate surgery is not required at this stage, which may reduce morbidity and mortality caused by immediate surgery and anaesthesia. Advances in knowledge: TT can be diagnosed easily by DWI without administrating any contrast material. DWI findings in the affected testicle may represent testicular salvageability.

AB - Lower levels of Intimate Relationship Quality (IRQ) have been found in those with Multiple Sclerosis (MS) compared to the general population. This study examined an MS sample to see whether IRQ was positively associated with self-concept, whether IRQ was positively associated with MS illness acceptance and whether IRQ was predicted by self-concept and illness acceptance. In this cross-sectional study, 115 participants with MS who were in an intimate relationship completed an online survey advertised on MS related websites. The survey assessed demographic variables, MS illness variables and levels of IRQ, self-concept and illness acceptance. Results revealed that IRQ was significantly positively associated with self-concept and with illness acceptance. Multiple hierarchical linear regression analysis revealed that, after controlling for illness duration and level of disability, self-concept significantly predicted IRQ but illness acceptance did not significantly predict IRQ. This study addressed several gaps and methodological flaws in the literature and was the first known to assess predictors of IRQ in those with MS. The results suggest that self-concept could be a potential target for individual and couple psychological interventions to improve IRQ and contribute to improved outcomes for those with MS.

PMID- 27690543 TI - Causes of variation in the neutrophil-lymphocyte and platelet-lymphocyte ratios: a twin-family study. AB - AIM: Neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) are biomarkers for disease development, for whom little is known about causes of variation in the general population. MATERIALS & METHODS: We estimated the heritability of PLR and NLR and examined their association with gender, demographic, lifestyle and environmental factors in a Dutch nonpatient twin family population (n = 8108). RESULTS: Heritability was estimated at 64% for PLR and 36% for NLR. Men had on average higher NLR, but lower PLR levels than women. PLR and NLR increased significantly with age, decreased in colder months and showed small but significant sex- and age-specific associations with body composition and smoking. CONCLUSION: NLR and PLR levels are heritable and influenced by age, sex and environmental factors, such as seasonal conditions and lifestyle.

PMID- 27690544 TI - Prevalence and psychosocial correlates of suicidal ideation among pregnant women living with HIV in Mpumalanga Province, South Africa. AB - Pregnant women living with HIV (WLHIV) in South Africa (SA) report higher rates of suicidal ideation than those who are HIV uninfected, and antenatal suicidal ideation has been previously associated with adverse maternal and neonatal outcomes. Few studies have attempted to identify correlates and psychosocial predictors of suicidal ideation in this population. In this study, we sought to estimate the prevalence of and identify risk factors for suicidal ideation among pregnant WLHIV in rural SA (N = 673). Thirty-nine percent of women endorsed suicidal ideation (95% CI: 35.2% to 42.3%) and in multivariable logistic regression analysis, suicidal ideation was associated with intimate partner violence and stigma, which interacted to multiplicatively increase the odds of suicidal thoughts. Given the high rates of reported suicidal ideation identified in this sample, and the potential harm to mothers and neonates, suicide risk assessment and management protocols for pregnant WLHIV should be considered for inclusion in the standard of care in rural SA.

AB - Biphasic responses of blood HCO3- concentration and H+ concentration following ingestion of 3 doses of NaHCO3 (0.1, 0.2, 0.3 g.kg-1) were assessed in 8 men. For HCO3- concentration, there were significant effects of dose on maximum responses and timing, as well amplitudes, onsets, and/or time constants of phases 1 and 2. Fewer significant effects of dose were observed for H+ concentration and additional data demonstrated differential effects of dose on HCO3- concentration and H+ concentration responses and underlying phases. PMID- 27690562 TI - Transactional sex among men who have sex with men in the French Antilles and French Guiana: frequency and associated factors. AB - The French Antilles (Martinique, Saint Martin and Guadeloupe) and French Guiana are the French territories most affected by the HIV epidemic. Some population groups such as men who have sex with men (MSM), especially those involved in transactional sex, are thought to be particularly vulnerable to HIV but few data exist to help characterize their health-related needs and thus implement relevant prevention interventions. To fill this knowledge gap, we used data collected from an HIV/AIDS Knowledge, Attitudes, Behaviours and Practices survey conducted in 2012 among MSM living in the French Antilles and French Guiana and recruited through snowball sampling. Our objectives were to compare social and demographic characteristics and sexual behaviours between MSM engaging in transactional sex and MSM not engaging in transactional sex and to identify factors associated with transactional sex involvement using a logistic regression model. A total of 733 MSM were interviewed, 21% of whom reported to undergo transactional sex. Their behaviour and social and demographic characteristics were different from other MSMs' and they were more exposed to factors that are recognized to potentiate HIV vulnerability, at the individual, community, network and structural levels. The variables positively associated with sex trade involvement were having ever consumed drug (OR = 2.84 [1.23-6.52]; p = .002), having a greater number of sex partners than the median (OR = 8.31 [4.84-14.30]; p < .001), having experienced intimate partner violence (OR = 1.72 [0.99-3.00]; p = .053) and having undergone physical aggression because of sexual orientation (OR = 2.84 [1.23-6.52]; p = .014). Variables negatively associated with sex trade involvement were being older (OR = 0.93 [0.90-0.97] per year; p = .001), having a stable administrative situation (OR = 0.10 [0.06-0.19]; p < .001), having a stable housing (OR = 0.29 [0.15-0.55]; p < .001) and being employed full-time (OR = 0.29 [1.23-6.52]; p = .002). PMID- 27690565 TI - Proton-pump inhibitor therapy and vitamin B12 status in an inpatient hospital setting. AB - The risk for impaired vitamin B12 status increases with age, as does the use of proton pump inhibitors (PPI). Long-term use of PPIs is associated with several nutritional deficiencies including B12. Currently, there are no recommendations for B12 screening among patients taking PPIs. Data were abstracted on B12 concentrations, B12-containing supplement use, medications, and select hematological values from a retrospective chart review of 658 adults, 391 with serum B12 concentrations, admitted to 6 different medical units at 2 regional hospitals in Southwestern Ontario between 2010 and 2012. We found no difference between PPI users and nonusers and serum B12 concentrations (404 +/- 224 vs 369 +/- 213 pmol/L; P = 0.0690). This may be due to use of B12 containing multivitamins in 41% of PPI users. Regression modelling found that aging increases the odds of having an impaired B12 status (<220 pmol/L) by 1.4 times and those using B12 supplements are almost 4 times more likely to have an impaired status. Mean corpuscular volume was not related to B12 status. In this population, older PPI users are more likely to be using multivitamins, which may delay nutritional deficiencies. However, the lower B12 concentrations of PPI users taking only B12 supplements is a concern and requires further research. Finally, physicians need to be aware that mean corpuscular volume is no longer recommended as an effective biomarker for B12 screening and updated screening protocols need to be used to reduce the possibility of adverse neurological effects from impaired B12 status. PMID- 27690566 TI - The effects of muscle action, repetition duration, and loading strategies of a whole-body, progressive resistance training programme on muscular performance and body composition in trained males and females. AB - Research has produced equivocal results with regard to eccentric (ECC) only compared with traditional concentric/eccentric resistance training (RT). When considered in relation to load- and repetition duration-accentuated (ECC) training as well as the use of isokinetic and isoinertial training methods, there is a relative dearth of literature considering multi-joint, multi-exercise RT interventions. The present study considered 59 male and female participants randomly divided in to 3 sex counterbalanced groups; ECC only (ECC, n = 20), repetition duration-accentuated ECC (ECC-A, n = 20), and traditional (CON, n = 19) performing full-body, effort matched RT programmes for 2 days.week-1 for 10 weeks. Outcomes were muscular performance, including absolute muscular endurance and predicted 1-repetition maximum, in addition to body composition. No significant between-groups differences were identified for change in muscular performance measures for leg press or chest press exercises, or for body composition changes. Analyses revealed a significantly greater improvement for CON compared with ECC groups (p < 0.05) for change in absolute muscular endurance for the pull-down exercise. Effect sizes for muscular performance changes were moderate to large for all groups and exercises (0.75-2.00). The present study supports previous research that ECC-only training produces similar improvements in muscular performance to traditional training where intensity of effort is controlled. Data herein further supports the use of uncomplicated, low-volume RT to momentary failure as an efficacious method of improving muscular performance in trained persons. PMID- 27690567 TI - The influence of subcutaneous fat on the relationship between body composition and ultrasound-derived muscle quality. AB - Ultrasound echo intensity (EI) values are a popular assessment of muscle quality. The relationship between EI and total (%fat) and regional (%fatlimb) body composition was examined in 40 men, prior to and after accounting for subcutaneous fat thickness. Uncorrected EI values suggest that muscle quality improves (r = -0.329 to -0.224; P = 0.038-0.165) with greater %fat and %fatlimb. However, corrected EI values indicated that muscle quality decreases (r = 0.711 to 0.798; P < 0.001) with greater %fat and %fatlimb.

AB - We evaluated the effects of exercise on circulating concentrations of guanidinoacetic acid (GAA) and creatine in 23 healthy volunteers subjected to running to exhaustion and free-weight bench-press to volitional failure. Blood was taken before and following each exercise session. Running induced a significant decrease in serum GAA by 20.1% (P < 0.001), while free-weight exercise reduced GAA by 11.7% (P < 0.001), suggesting the possible use of serum GAA as a novel biomarker of exhaustion. PMID- 27690569 TI - Short-term green tea extract supplementation attenuates the postprandial blood glucose and insulin response following exercise in overweight men. AB - Green tea extract (GTE) ingestion improves glucose homeostasis in healthy and diabetic humans, but the interactive effect of GTE and exercise is unknown. The present study examined the effect of short-term GTE supplementation on the glycemic response to an oral glucose load at rest and following an acute bout of exercise, as well as substrate oxidation during exercise. Eleven sedentary, overweight men with fasting plasma glucose (FPG) >=5.6 mmol.L-1 (age, 34 +/- 13 years; body mass index = 32 +/- 5 kg.m-2; FPG = 6.8 +/- 1.0; mean +/- SD) ingested GTE (3* per day, 1050 mg.day-1 total) or placebo (PLA) for 7 days in a double-blind, crossover design. The effects of a 75-g glucose drink were assessed on 4 occasions during both GTE and PLA treatments: On days 1 and 5 at rest, and again following an acute bout of exercise on days 3 and 8. The glycemic response was assessed via an indwelling continuous glucose monitor (CGM) and venous blood draws. At rest, 1-h CGM glucose area under the curve was not different (P > 0.05), but the postexercise response was lower after GTE versus PLA (330 +/- 53 and 393 +/- 65 mmol.L-1.min-1, main effect of treatment, P < 0.05). The 1-h postprandial peaks in venous blood glucose (8.6 +/- 1.6 and 9.8 +/- 2.2 mmol.L-1) and insulin (96 +/- 59 and 124 +/- 68 MUIU.ml-1) were also lower postexercise with GTE versus PLA (time * treatment interactions, P < 0.05). In conclusion, short-term GTE supplementation did not affect postprandial glucose at rest; however, GTE was associated with an attenuated glycemic response following a postexercise oral glucose load. These data suggest that GTE might alter skeletal muscle glucose uptake in humans. PMID- 27690570 TI - Memory Enhancement by Bryostatin in Hermissenda.

AB - Perinatal HIV is associated with significant neurocognitive morbidities, but few studies have examined cognitive impact of early HIV infection on patients surviving to adulthood. The purpose of this study was to evaluate neurocognitive outcomes among a cohort of perinatally infected young adults. Individuals between the ages of 18 and 24 with perinatal infection were recruited for this cross sectional study along with similarly aged healthy controls. Participants completed an MRI and brief neuropsychological assessment battery. Multivariate analysis of covariance controlling for age, gender, race/ethnicity, and education was completed to detect differences between the HIV+ and control groups. Multivariable linear regression was performed to assess HIV-associated factors potentially impacting neuropsychological findings among the HIV+ group. Twenty nine HIV+ young adults and 13 healthy controls were included in the study. After adjusting for age and sociodemographic variables, the HIV+ group scored lower on attention/working memory (Digit Span (p = .008) and Letter-Number Sequencing (p = .038)), set-shifting (DKEFS Trail Making Test Condition 4 (p = .026) and motor speed (DKEFS Trail Making Test Condition 5 (p = .003)). For the HIV+ group, nadir CD4 was associated with better Letter-Number Sequencing score (p = .029) and use of highly active antiretroviral therapy was associated with better performance on Category Fluency (p = .040). After controlling for sociodemographic variables, executive dysfunction persists among young adults with perinatal HIV infection in comparison to controls. Future studies to further elucidate the impact of executive dysfunction on independent living and functional outcomes are indicated.

AB - INTRODUCTION: Congenital heart defects are frequently present in patients with Down syndrome. AIM: The authors analyzed the impact of changing approach in surgical management of congenital heart defect on the life expectancy of patients with Down syndrome. METHOD: Between 1974 and 1997 the data of 359 children with Down syndrome were collected. Among them 255 patients had no surgery and the mortality in this group was 25.9%, whereas the mortality in the group of 104 patients who underwent palliative surgery was 8.6%. RESULTS: Surgical management of congenital heart defects provides the same life expectancy for these patients as compared to Down patients without cardiac defects. Primary reconstruction is the preferable surgical procedure in infancy that provides good results. Nowadays the number of the operated grown-up congenital heart disease patients with Down syndrome is increasing. During the last three years 82 grown-up congenital heart disease patients, including 4 patients with Down syndrome (aged between 24 and 60 years) were reconstructed successfully. CONCLUSIONS: Due to the successful surgery in infancy the population of grown-up congenital heart disease patients with Down syndrome is increasing. The cardiac surgeons are ready to do everything for the optimal life expectancy of these patients. However, management of special problems (indication and necessity of reoperation, optimal age) in patients with Down syndrome poses a great challenge for cardiologists and cardiac surgeons. Orv.

PMID- 27690619 TI - Characteristics of intermittent smokers and their association with quit intentions in a sample of heavy-drinking HIV-infected men who have sex with men. AB - Intermittent smokers (ITS) have increased health risks compared with non-smokers (NS). Cigarette smoking remains prevalent among men who have sex with men (MSM) and persons living with HIV (PLWH), yet most studies in PLWH do not discriminate between daily smokers (DS) and ITS. In this study, the characteristics and quit intentions of ITS and DS are compared in a sample of heavy-drinking HIV-infected MSM. Of the 185 participants enrolled, 49.2% reported having smoked cigarettes in the past month; among those, 50.5% were DS, and 49.5% were ITS. Compared with DS, ITS were significantly more likely to be White and to have a college degree or higher. DS reported significantly higher average number of drinks per week compared with both ITS and NS. Compared with DS, ITS were significantly more likely to report future quit intentions (i.e., within 6 months or more) compared to no intentions at all; DS were more likely to report immediate quit intentions (i.e., within 30 days) compared to future quit intentions. Among heavy-drinking MSM living with HIV, intermittent smoking was associated with being White, college educated, and having future quit intentions. Considering that smoking in ITS may be less driven by nicotine dependence, tailored approaches to smoking cessation may be needed. Specifically, it may be important for interventions for ITS to address social and situational cues to smoke, including the influence of heavy alcohol use on smoking behaviors, and to provide information regarding the adverse health effects of even low-level smoking. PMID- 27690621 TI - [A rare zoonosis in Hungary: cercarial dermatitis caused by Schistosoma turkestanicum blood-fluke]. AB - Several trematodes that parasitize vertebrate animals utilize swimming aquatic larvae to infect the host percutaneously. The most important ones among these parasites are the blood-flukes of birds and mammals comprising species that are also zoonotic. Within this latter group are species that cause the bilharziasis or schistosomiasis of inhabitants of the tropical countries, and other trematode species that are able to penetrate human skin, but do not develop to an adult form of the worm in the body. In temperate climates this latter type of infection occurs mainly in the form of an unpleasant inflammation of the skin and is often called "swimmer's itch". In most of these cases, the origin of the larvae remains unexplored, the source of the infection is neglected by the medical or veterinarian practitioners. Herein we report for the first time in Hungary that the cause of such dermatitis was the cercariae of Schistosoma turkestanicum, which infected red deer (Cervus elaphus) in this country. The local name of this pristine disease is "water mange" and it occurs only in one of the floodplains of the Danube. On the basis of informal communication this symptom seems to be rather regular among people who do fishing or have a bath in the habitat of the blood-fluke. In the case of adequate anamnesis it is worth examining the origin of the cercarial dermatitis which may give cross-reactions with human schistosomiasis during serological tests. Orv.

AB - Ramucirumab is a humanized monoclonal antibody against vascular endothelial growth factor receptor-2, which inhibits the binding of vascular endothelial growth factor-A, -C and -D ligands. Furthermore it blocks the ligand stimulated activation of p44/p42 mitogen activated protein kinases, thus neutralizing the ligand induced proliferation and migration of human endothelial cells. Based on the results of the REGARD (Ramucirumab monotherapy for previously treated advanced gastric or gastro-oesophageal junction adenocarcinoma) and the RAINBOW (Ramucirumab plus paclitaxel versus placebo plus paclitaxel in patients with previously treated advanced gastric or gastro-oesophageal junction adenocarcinoma) studies ramucirumab was approved for 2nd line treatment as monotherapy and in combination with paclitaxel for patients with local relapse and unresectable or metastatic gastric cancer (including gastro-esophegal junction adenocarcinoma). Based on the results, in advanced solid malignancies, ramucirumab may prolong progression free survival and overall survival, although it may increase the risk of all adverse events (fatigue, neutropenia, haemorrhage, nausea, stomatitis). The authors review the clinical studies of ramucirumab. Orv. Hetil., 2016, 157(40), 1587-1594. PMID- 27690624 TI - [Active euthanasia, or assisted suicide?] AB - INTRODUCTION: Both active euthanasia and assisted suicide are legal in The Netherlands, Belgium, Luxemburg and, most recently, in Canada. AIM: Examination of national legislations of countries where both active euthanasia and assisted suicide are legal. The number of accomplished active euthanasia cases and that of assisted suicide cases. METHOD: Analysis of national statistical data. Comparison of statistical data before and after 2010. Comparison of the related practices in the surveyed countries. RESULTS: The number of active euthanasia cases markedly predominates over the number of assisted suicide cases. Cancer is a main reason for active euthanasia, or assisted suicide. In countries with a larger population, the number of active euthanasia cases is higher than that in countries with a smaller population. CONCLUSIONS: Regarding the fact that the applicants for active euthanasia withdraw their requests in a smaller number than the applicants for assisted suicide, patients prefer the choice of active euthanasia. Since the related legislative product is too recent in Canada at present, it may be only presumed that a certain preference will also develop in the related practices in Canada. Orv.

AB - In a randomized between-subjects design, participants (N = 80) were assigned to one of four conditions, 2 (pregnant, not pregnant) * 2 (extreme prime, moderate prime). It was hypothesized that primes involving moderate mental illness would be positively associated with increased perceived risk of developing postpartum depression. Hayes and Preacher's bootstrapping procedure was used to test the direct, indirect, and conditional indirect effects related to the hypothesized model. In addition, further analyses evaluated whether implicitly activated goals (to be healthy or to be a good mother) were positively associated with increased perceptions of risk and engagement of downstream avoidance behavioral intentions. Findings show that for pregnant participants, the effect of the prime condition on perceived personal risk of developing postpartum depression was mediated by perceptions about the target character's sanity. However, activated "healthy" and "good mother" goals are not influencing behavioral intentions. PMID- 27690627 TI - One new flavanocoumarin from the thorns of Gleditsia sinensis. AB - One new flavanocoumarin (1), as well as six known flavonoids (2-7), was isolated from the ethyl acetate extract of the thorns of Gleditsia sinensis. The structures of these compounds were elucidated by extensive spectroscopic measurements and comparison with data reported in literatures. Cytotoxic activities of compounds 1-6 were evaluated against human liver cancer SK-hep-1 cells in vitro by the MTT method, with compound 1 displaying moderate activity (IC50 of 62.53 MUM). Furthermore, compound 1 could increase the number of apoptosis cells in a concentration-dependent manner. PMID- 27690628 TI - Synthesis and antioxidant activity of curcumin analogs. AB - Numerous biological activities including antioxidant, antitumor, anti inflammation, and antivirus of the natural product curcumin were reported. However, the clinical application of it was significantly limited by its instability, poor solubility, less body absorbing, and low bioavailability. This review focuses on the structure modification and antioxidant activity evaluation of curcumin. To study the structure-activity relationship (SAR), five series of curcumin analogs were synthesized and their antioxidant activity were evaluated in vitro. The results showed that electron-donating groups, especially the phenolic hydroxyl group are an essential component to improve the antioxidant activity. PMID- 27690629 TI - Optimizing antifungal strategies to improve patient survival. AB - Report from the 26th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID 2016), 9-12 April Amsterdam, The Netherlands Invasive fungal infections are a major threat to the lives of the increasing number of immunocompromized patients, but neutropenic hemato-oncology patients are at especially high risk. Since effective antifungal treatment and prophylaxis are critical to improve survival in these patients, the emergence of antifungal drug resistance has become an increasing cause of concern. Mortality from invasive fungal infection also remains high even when patients receive appropriate and timely antifungal therapy. These important topics were among those discussed by the over 11,600 clinical microbiologists and infectious disease physicians from more than 120 countries attending the 26th European Congress of Clinical Microbiology and Infectious Diseases. PMID- 27690630 TI - Examining How Racial Discrimination Impacts Sleep Quality in African Americans: Is Perseveration the Answer? AB - BACKGROUND: African Americans experience more problematic and disordered sleep than White Americans. Racial discrimination has been implicated in this disparity. However, the mechanisms by which discrimination disrupts sleep are unclear. It has been theorized that Perseverative Cognition (PC), characterized by recurrent patterns of reflective (i.e., rumination) and anticipatory (i.e., worry) negative thinking about personally relevant stressors, may reflect the functional mechanism linking discrimination to sleep. The present study is the first to empirically examine the dual components of PC as a candidate functional mechanism in the association between racial discrimination and subjective sleep quality. PARTICIPANTS: Sixty-eight self-identified African American college students (55.9% female; Mage = 20.18, SD = 2.93) were recruited at a large predominantly white public university in the Midwest. METHODS: The participants completed the Perceived Ethnic Discrimination Questionnaire (PEDQ), Pittsburgh Sleep Quality Index (PSQI), Penn State Worry Questionnaire (PSWQ), and Ruminative Responses Scale (RRS). RESULTS: After adjusting for age, gender, and social class, results revealed a significant indirect effect of racial discrimination (RD) on subjective sleep quality through rumination, 95% CI [.008, .125], but not worry. RD was positively associated with rumination, b =.50, SE =.16, p = .003, and rumination, in turn, was positively associated with poorer sleep quality, b = .09, SE = .04, p = .012. CONCLUSIONS: As both RD and poor sleep quality have been directly linked to heart disease, diabetes, depression, and a number of other maladies, our findings suggest that RD, sleep, and coping strategies (e.g., rumination) employed to manage RD experiences may be important targets for addressing racial disparities in health. PMID- 27690632 TI - 3D CT scan for perioperative identification of anatomical variations of lungs. AB - AIM: The aim of this study is to investigate anatomical lung variations and vascular patterns using volumetric 3D computed tomography (CT) representations. METHODS & RESULTS: We considered 24 major thoracic surgery performed in our ward. In these, we discovered some interesting anatomical variations of the main pulmonary fissures. These findings were not visible on the plain x-ray or during routine examination of a preoperative CT scan. After re-examination of 3D CT scan reconstruction the anatomical variations were detected. DISCUSSION: General thoracic surgeons must familiarize themselves with anatomical variations in lungs. 3D images may aid the general thoracic surgeon in performing safer surgeries. CONCLUSION: 3D CT scan should be performed before surgery if possible. PMID- 27690631 TI - HOTAIR rs920778 polymorphism is associated with ovarian cancer susceptibility and poor prognosis in a Chinese population. AB - AIM: The aim of this study was to determine if HOTAIR rs920778 polymorphism is associated with ovarian cancer susceptibility and prognosis. MATERIALS & METHODS: The data were obtained from two independent groups including 329 ovarian cancer patients and 680 cancer-free, age-matched women. Blood samples were collected and genomic DNA was extracted for genotyping. RESULTS: TT genotype and T allele of HOTAIR rs920778 were significantly associated with a decreased ovarian cancer risk (p = 0.0004 and p < 0.0001, respectively), which associated with advanced tumor stage, lymph node metastasis and poor prognosis. Moreover, TT and TC carriers obtained a much shorter survival (p = 0.026). CONCLUSION: These findings propose that HOTAIR rs920778 polymorphism influences ovarian cancer susceptibility and prognosis, and further studies are warranted in other populations. PMID- 27690633 TI - A new flavonol glycoside from the aerial parts of Epimedium koreanum Nakai. AB - A new prenylated flavonol glycoside (1) was isolated from a 95% methanol extract of the dried and powdered aerial parts of Epimedium koreanum Nakai (Herba Epimedii), along with seven previously known flavonoids (2-8). The chemical structure of the new compound (1) was established to be 5-hydroxy-4'-methoxy-8-(2 hydroxy-3-methyl-3-butenyl)flavone 3-O-alpha-l-rhamnopyranosyl-7-O-beta-D-gluco pyranoside on the basis of spectroscopic methods. The antioxidant activities of these compounds were determined by the DPPH (2,2-diphenyl-1-picrylhydrazyl) free radical scavenging assay and kaempferitrin (8) showed a high reactivity with DPPH. PMID- 27690635 TI - Development and Evaluation of the Sugar-Sweetened Beverages Media Literacy (SSB ML) Scale and Its Relationship With SSB Consumption. AB - Understanding how adults' media literacy skill sets impact their sugar-sweetened beverage (SSB) intake provides insight into designing effective interventions to enhance their critical analysis of marketing messages and thus improve their healthy beverage choices. However, a media literacy scale focusing on SSBs is lacking. This cross-sectional study uses baseline data from a large randomized controlled trial to (a) describe the psychometric properties of an SSB Media Literacy Scale (SSB-ML) scale and its subdomains, (b) examine how the scale varies across demographic variables, and (c) explain the scale's concurrent validity to predict SSB consumption. Results from 293 adults in rural southwestern Virginia (81.6% female, 94.0% White, 54.1% receiving SNAP and/or WIC benefits, average 410 SSB kcal daily) show that overall SSB-ML scale and its subdomains have strong internal consistencies (Cronbach's alphas ranging from 0.65 to 0.83). The Representation & Reality domain significantly predicted SSB kilocalories, after controlling for demographic variables. This study has implications for the assessment and inclusion of context-specific media literacy skills in behavioral interventions. PMID- 27690636 TI - Reducing Resistance to Narrative Persuasion About Binge Drinking: The Role of Self-Activation and Habitual Drinking Behavior. AB - This study explores the effects of habitual health risk behaviors and self activation on resistance to narrative persuasion. In two experiments, heavier drinkers were more resistant to an anti-binge-drinking narrative public service announcement (PSA) in which a binge drinker suffers a negative outcome. Specifically, heavier drinkers were more likely to generate counterarguments, unrealism judgments, and negative evaluations about the message compared to lighter drinkers or nondrinkers. However, activating self-concept when processing the persuasive narrative reduced unrealism judgments and negative evaluations, particularly among heavier drinkers. Self-activation also decreased perceived freedom threat among both heavier and lighter drinkers, which further led to higher perceived risk of binge drinking. Theoretical and practical implications are discussed. PMID- 27690634 TI - Caregiving-Related Sleep Problems and Their Relationship to Mental Health and Daytime Function in Female Veterans. AB - OBJECTIVE/BACKGROUND: To identify caregiving-related sleep problems and their relationship to mental health and daytime function in female Veterans. PARTICIPANTS: Female Veterans (N = 1,477) from cross-sectional, nationwide, postal survey data. METHODS: The survey respondent characteristics included demographics, comorbidity, physical activity, health, use of sleep medications, and history of sleep apnea. They self-identified caregiving- related sleep problems (i.e., those who had trouble sleeping because of caring for a sick adult, an infant/child, or other respondents). Patient Health Questionnaire (PHQ 4) was used to assess mental health, and daytime function was measured using 11 items of International Classification of Sleep Disorders-2 (ICSD-2). RESULTS: Female Veterans with self-identified sleep problems due to caring for a sick adult (n = 59) experienced significantly more symptoms of depression and anxiety (p < 0.001) and impairment in daytime function (e.g., fatigue, daytime sleepiness, loss of concentration, p < 0.001) than those with self-identified sleep problems due to caring for an infant or child (n = 95) or all other respondents (n = 1,323) after controlling for the respondent characteristics. CONCLUSIONS: Healthcare providers should pay attention to assessing sleep characteristics of female Veterans with caregiving responsibilities, particularly those caregiving for a sick adult. PMID- 27690637 TI - Referential communication abilities in children with 22q11.2 deletion syndrome. AB - PURPOSE: This study describes the performance on a perspective- and role-taking task in 27 children, ages 6-13 years, with 22q11.2 deletion syndrome (22q11.2DS). A cross-cultural design comparing Dutch- and English-speaking children with 22q11.2DS explored the possibility of cultural differences. METHOD: Chronologically age-matched and younger typically developing (TD) children matched for receptive vocabulary served as control groups to identify challenges in referential communication. RESULTS: The utterances of children with 22q11.2DS were characterised as short and simple in lexical and grammatical terms. However, from a language use perspective, their utterances were verbose, ambiguous and irrelevant given the pictured scenes. They tended to elaborate on visual details and conveyed off-topic, extraneous information when participating in a barrier game procedure. Both types of aberrant utterances forced a listener to consistently infer the intended message. Moreover, children with 22q11.2DS demonstrated difficulty selecting correct speech acts in accordance with contextual cues during a role-taking task. CONCLUSION: Both English- and Dutch speaking children with 22q11.2DS showed impoverished information transfer and an increased number of elaborations, suggesting a cross-cultural syndrome-specific feature. PMID- 27690638 TI - Effectively Coping With Task Stress: A Study of the Validity of the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF). AB - In this study, we investigated the validity of the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF; Petrides, 2009) in the context of task induced stress. We used a total sample of 225 volunteers to investigate (a) the incremental validity of the TEIQue-SF over other predictors of coping with task induced stress, and (b) the construct validity of the TEIQue-SF by examining the mechanisms via which scores from the TEIQue-SF predict coping outcomes. Results demonstrated that the TEIQue-SF possessed incremental validity over the Big Five personality traits in the prediction of emotion-focused coping. Results also provided support for the construct validity of the TEIQue-SF by demonstrating that this measure predicted adaptive coping via emotion-focused channels. Specifically, results showed that, following a task stressor, the TEIQue-SF predicted low negative affect and high task performance via high levels of emotion-focused coping. Consistent with the purported theoretical nature of the trait emotional intelligence (EI) construct, trait EI as assessed by the TEIQue SF primarily enhances affect and performance in stressful situations by regulating negative emotions. PMID- 27690639 TI - Discard the Smoking Cues-Keep the Disgust: An Investigation of Tobacco Smokers' Motivated Processing of Anti-tobacco Commercials. AB - This study experimentally examines the effect of smoking cues and disgust images commonly found in anti-tobacco advertisements on tobacco smokers' message processing. In a 2 (smoking cues) * 2 (disgust) within-subjects experiment, smokers watched anti-tobacco advertisements selected to vary in presence/absence of smoking cues and high/low ratings of disgust. The results of the experiment suggest that smoking cues and disgust images each have effects on resource allocation, recognition memory, emotional responses, smoking urges, and intentions to quit smoking. However, the most notable finding in this study was how the combination of smoking cues and disgust images in a single anti-tobacco message resulted in defensive message processing. Theoretical and applied implications of these findings are discussed along with future research directions. PMID- 27690640 TI - Role of catalase overproduction in drug resistance and virulence in Candida albicans. AB - AIM: To investigate the role of Cat1 overproduction in Candida albicans. MATERIALS & METHODS: Strains overproducing the CAT1 gene were constructed. RESULTS: Cells overproducing CAT1 were found to be more resistant to some oxidants and mammalian phagocytic cells. They also showed reduced intracellular reactive oxygen species generated by amphotericin B or ciclopirox olamine. CAT1 overproduction did not change the minimum inhibitory concentration of fungal cells to fungistatic or fungicidal azoles nor to amphotericin B although increased twofold the minimum inhibitory concentration to caspofungin. The role of Cat1 overproduction in virulence and colonization was also analyzed in mouse models. CONCLUSION: The overproduction of Cat1 protects against oxidants, phagocytes and certain antifungals at subinhibitory concentration but does not increase virulence in a systemic infection mouse model. PMID- 27690641 TI - Chemical constituents of Cinnamomum septentrionale leaf litter and its allelopathic activity on the growth of maize (Zea mays). AB - A pot experiment was conducted to study the effect of decomposing Cinnamomum septentrionale leaf litter on the growth of maize. In this study, the morphological traits of maize were significantly inhibited when the leaf litter amount reached or exceeded 40 g per pot; Furthermore, during the early growth stage or with a large amount of litter addition, the pigment contents were inhibited by C. septentrionale leaf litter. Gas chromatography-mass spectrometry was used to determine the volatile substances of leaf litter and 34 compounds were identified, several of which were reported to be phytotoxic. In conclusion, the leaf litter of C. septentrionale showed a strong allelopathic effect on the growth of maize. Thus, it is better to avoid the growing of maize under or near the C. septentrionale plantation unless the leaf litter could be eliminated in time or other effective leaf litter processing methods could be implemented. PMID- 27690642 TI - Regulatory T CD4 + CD25+ lymphocytes increase in symptomatic carotid artery stenosis. AB - BACKGROUND: Atherosclerosis is a multifactorial disease characterized by an immune-inflammatory remodeling of the arterial wall. Treg and Th17 subpopulations are detectable inside atherosclerotic plaque; however, their behavior in symptomatic carotid artery stenosis (CAS) is not fully elucidated. The aim of this study was to evaluate Th17 and Treg subsets and their ratio in patients affected by symptomatic and asymptomatic CAS. METHODS: 14 patients with symptomatic CAS (CAS-S group), 41 patients with asymptomatic CAS (CAS-A group), 32 subjects with traditional cardiovascular risk factors (RF group), and 10 healthy subjects (HS group) were enrolled. Th17 and Treg frequency was determined by flow cytometry and by histology and immunohistochemistry. Interleukin (IL)-10, IL-17, and metalloproteinase (MMP)-12 levels were measured by ELISA. RESULTS: Th17 were significantly increased in CAS-A versus RF and versus HS. Tregs were significantly increased in CAS-S versus CAS-A. Tregs/Th17 ratio was significantly reduced in CAS-A versus RF and versus HS, whereas it was significantly increased in CAS-S versus CAS-A. CONCLUSIONS: The results of this study suggest that Th17 are related to the late stages of CAS but not to plaque instability. Moreover, Treg expansion seems to represent a specific cellular pattern displayed by patients with symptomatic CAS and associated with brain injury. KEY MESSAGES Tregs expansion seems to represent a specific cellular pattern displayed by patients with symptomatic CAS and associated with CD4+ effector depletion and brain ischemic injury. Th17 lymphocytes are related to the late stages of CAS but not to plaque instability. PMID- 27690643 TI - Helsinn: 20 years in primary cancer supportive care.

PMID- 27690644 TI - Isolation, structure elucidation, and induction of hepatoma cell apoptosis of abietane diterpenoids from Abies faxoniana. AB - Two new abietane diterpenoids (1-2) and 13 known compounds (3-15) were characterized from the branches and leaves of Abies faxoniana. The chemical structures of the new diterpenoids (1-2) were determined through the analysis of various 1D/2D NMR techniques. Compound 3 is 151,617-trinor-abietane diterpenoid conjugated with a three-membered epoxide ring. The isolated diterpenoids were tested for their cytotoxicities. Among them, compound 3 exhibited the strongest antiproliferative effect against human hepatoma cell SMMC7721 with an IC50 value of 12.5 MUM. To elucidate the preliminary mechanism responsible for compound 3 induced inhibition of cell proliferation, we investigated the effects of compound 3 on apoptosis, cell cycle progression, and reactive oxygen species generation in SMMC7721 cells. The results showed that compound 3 induced cell apoptosis and excessive ROS production, but did not change the cell cycle distribution in SMMC7721 cells. PMID- 27690645 TI - Augmenting effect of vitrification on lipid peroxidation in mouse preantral follicle during cultivation: Modulation by coenzyme Q10. AB - Cryopreservation-induced oxidative stress (OS) may lead to lipid peroxidation, which may be responsible for decreased cell survival rate. Coenzyme Q10 (CoQ10) as a potent antioxidant may improve cell viability by neutralizing OS. In this study, oxidative lipid injury following the vitrification of preantral follicles was investigated. The effects of CoQ10 treatment on the malondialdehyde (MDA) levels, lipid peroxidation products, and activities of enzymatic and nonenzymatic antioxidants of vitrified preantral follicles were also studied. Preantral follicles were isolated from immature mouse ovaries and were vitrified. After warming, these follicles were cultured with or without CoQ10 for four days. The levels of total antioxidant capacity (TAC) and MDA, as well as the activities of superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT), were assessed at 0, 24, 48, 72, and 96 hours of culture period. The MDA level in the vitrified preantral follicles was higher than that in the fresh groups. By contrast, the MDA level was significantly lower in the groups with CoQ10 treatment than in those without this treatment during cultivation. The TAC level was higher in the fresh preantral follicles than in the vitrified groups. The rates were also higher in the CoQ10-treated groups than in those without this treatment. The activities of SOD, GPX, and CAT were also significantly higher in the fresh groups than in the vitrified groups, especially in the groups with CoQ10 treatment than in those without this treatment. Lowering the vitrification induced lipid peroxidation of preantral follicles by CoQ10-supplemented maturation medium may be mediated by increasing SOD, GPX, and CAT activities and TAC level during cultivation. PMID- 27690646 TI - Laser interstitial thermal therapy for subependymal giant cell astrocytoma: technical case report. AB - Subependymal giant cell astrocytoma (SEGA) is a rare tumor occurring almost exclusively in patients with tuberous sclerosis complex. Although open resection remains the standard therapy, complication rates remain high. To minimize morbidity, less invasive approaches, such as endoscope-assisted resection, radiosurgery, and chemotherapy with mTOR pathway inhibitors, are also used to treat these lesions. Laser interstitial thermal therapy (LITT) is a relatively new modality that is increasingly used to treat a variety of intracranial lesions. In this report, the authors describe two pediatric cases of SEGA that were treated with LITT. In both patients the lesion responded well to this treatment modality, with tumor shrinkage observed on follow-up MRI. These cases highlight the potential of LITT to serve as a viable minimally invasive therapeutic approach to the management of SEGAs in the pediatric population.

PMID- 27690648 TI - Safety of stereotactic laser ablations performed as treatment for glioblastomas in a conventional magnetic resonance imaging suite. AB - OBJECTIVE Stereotactic laser ablation (SLA) is typically performed in the setting of intraoperative MRI or in a staged manner in which probe insertion is performed in the operating room and thermal ablation takes place in an MRI suite. METHODS The authors describe their experience, in which SLA for glioblastoma (GBM) treatment was performed entirely within a conventional MRI suite using the SmartFrame stereotactic device. RESULTS All 10 patients with GBM (2 with isocitrate dehydrogenase 1 mutation [mIDH1] and 8 with wild-type IDH1 [wtIDH1]) were followed for > 6 months. One of these patients underwent 2 independent SLAs approximately 12 months apart. Biopsies were performed prior to SLA for all patients. There were no perioperative morbidities, wound infections, or unplanned 30-day readmissions. The average time for a 3-trajectory SLA (n = 3) was 436 +/- 102 minutes; for a 2-trajectory SLA (n = 4) was 321 +/- 85 minutes; and for a single-trajectory SLA (n = 4) was 254 +/- 28 minutes. No tumor recurrence occurred within the blue isotherm line ablation zone, although 2 patients experienced recurrence immediately adjacent to the blue isotherm ablation line. Overall survival for the patient cohort averaged 356 days, with the 2 patients who had mIDH1 GBMs exhibiting the longest survival (811 and 654 days). CONCLUSIONS Multitrajectory SLA for treatment of GBM can be safely performed using the SmartFrame stereotactic device in a conventional MRI suite.

A wide variety of techniques for placement of the laser fiber have been reported with a spectrum of perceived benefits and drawbacks. The authors present the first report of a customized 3D printed stereotactic frame for LITT. Approximately 1 week prior to surgery, 3-4 skull fiducials were placed after each of 5 patients received a local anesthetic as an outpatient. Radiographs with these fiducials were then used to create a trajectory to the lesion that would be treated with LITT. After the plan was completed, software was used to render a customized frame. On the day of surgery, the frame was attached to the implanted skull fiducials and the LITT catheter was placed. This procedure was carried out in 5 consecutive patients. In 2 patients, a needle biopsy was also performed. Intraoperative and postoperative imaging studies confirmed the accurate placement of the LITT catheter and the lesion created. Mean operating room time for all patients was 45 minutes but only 26 minutes when excluding the cases in which a biopsy was performed. To the best of the authors' knowledge, this is the first report of the use of a specific system, the STarFix microTargeting system, for use with LITT and brain biopsy. This system offers several advantages including fast operating times, extensive preoperative planning, no need for cranial fixation, and no need for frame or fiducial placement on the day of surgery. The accuracy of the system combined with these advantages may make this a preferred stereotactic method for LITT, especially in centers where LITT is performed in a diagnostic MRI suite.

AB - OBJECTIVE Hypothalamic hamartomas (HHs) are associated with gelastic seizures and the development of medically refractory epilepsy. Magnetic resonance imaging guided laser interstitial thermal therapy (MRg-LITT) is a minimally invasive ablative treatment that may have applicability for these deep-seated lesions. Here, the authors describe 3 patients with refractory HHs who they treated with MRg-LITT. METHODS An institutional review board-approved prospective database of patients undergoing Visualase MRg-LITT was retrospectively reviewed. Demographic and historical medical data, including seizure and medication histories, previous surgeries, procedural details, and surgical complications, along with radiological interpretation of the HHs, were recorded. The primary outcome was seizure freedom, and secondary outcomes included medication reduction, seizure frequency, operative morbidity, and clinical outcome at the latest follow-up. RESULTS All 3 patients in the multi-institutional database had developed gelastic seizures related to HH at the ages of 7, 7, and 9 years. They presented for further treatment at 25, 28, and 48 years of age, after previous treatments with stereotactic radiosurgery in all cases and partial hamartoma resection in one case. One ablation was complicated by a small tract hemorrhage, which was stable on postoperative imaging. One patient developed hyponatremia and experienced weight gain, which were respectively managed with fluid restriction and counseling. At the most recent follow-up at a mean of 21 months (range 1-32 months), one patient was seizure free while another had meaningful seizure reduction. Medication was reduced in one case. CONCLUSIONS Adults with gelastic seizures despite previous treatments can undergo MRg-LITT with reasonable safety and efficacy. This novel therapy may provide a minimally invasive alternative for primary and recurrent HH as the technique is refined. PMID- 27690652 TI - Utilizing personalized stereotactic frames for laser interstitial thermal ablation of posterior fossa and mesiotemporal brain lesions: a single-institution series. AB - OBJECTIVE The precision of laser probe insertion for interstitial thermal therapy of deep-seated lesions is limited by the method of stereotactic guidance. The objective of this study was to evaluate the feasibility of customized STarFix 3D printed stereotactic platforms to guide laser probe insertion into mesiotemporal and posterior fossa targets. METHODS The authors conducted a retrospective review of 5 patients (12-55 years of age) treated with laser interstitial thermal therapy (LITT) in which STarFix platforms were used for probe insertion. Bone fiducials were implanted in each patient's skull, and subsequent CT scans were used to guide the design of each platform and incorporate desired treatment trajectories. Once generated, the platforms were mounted on the patients' craniums and used to position the laser probe during surgery. Placement of the laser probe and the LITT procedure were monitored with intraoperative MRI. Perioperative and follow-up MRI were performed to identify and monitor changes in target lesions. RESULTS Accurate placement of the laser probe was observed in all cases. For all patients, thermal ablation was accomplished without intraoperative complications. Of the 4 patients with symptomatic lesions, 2 experienced complete resolution of symptoms, and 1 reported improved symptoms compared with baseline. CONCLUSIONS Customized stereotactic platforms were seamlessly incorporated into the authors' previously established LITT workflow and allowed for accurate treatment delivery. PMID- 27690653 TI - Thermal injury to corticospinal tracts and postoperative motor deficits after laser interstitial thermal therapy. AB - OBJECTIVE Laser interstitial thermal therapy (LITT) has been increasingly used to treat deep-seated tumors. Despite its being minimally invasive, there is a risk of LITT damaging adjacent critical structures, including corticospinal tracts (CSTs). In this study, the authors investigated the predictive value of overlap between the hyperthermic field and CSTs in determining postoperative motor deficit (PMDs). METHODS More than 140 patients underwent an LITT procedure in our institution between April 2011 and June 2015. Because of the tumor's proximity to critical structures, 80 of them underwent preoperative diffusion tensor imaging and were included in this study. Extent of the hyperthermic field was delineated by the software as thermal-damage-threshold (TDT) lines (yellow [43 degrees C for 2 minutes], blue [43 degrees C for 10 minutes], and white [43 degrees C for 60 minutes]). The maximum volume and the surface area of overlaps between motor fibers and the TDT lines were calculated and compared with the PMDs. RESULTS High grade glioma (n = 46) was the most common indication for LITT. Postoperative motor deficits (partial or complete) were seen in 14 patients (11 with permanent and 3 with temporary PMDs). The median overlap volumes between CSTs with yellow, blue, and white TDT lines in patients with any PMD (temporary or permanent) were 1.15, 0.68, and 0.41 cm3, respectively. The overlap volumes and surface areas revealed significant differences in those with PMDs and those with no deficits (p = 0.0019 and 0.003, 0.012 and 0.0012, and 0.001 and 0.005 for the yellow, blue, and white TDT lines, respectively). The receiver operating characteristic was used to select the optimal cutoff point of the overlapped volumes and areas. Cutoff points for overlap volumes and areas based on optimal sensitivity (92% 100%) and specificity (80%-90%) were 0.103, 0.068, and 0.046 cm3 and 0.15, 0.07, and 0.11 mm2 for the yellow, blue, and white TDT lines, respectively. CONCLUSIONS Even a minimal overlap between the TDT lines and CSTs can cause a PMD after LITT. Precise planning and avoidance of critical structures and important white matter fibers should be considered when treating deep-seated tumors. PMID- 27690654 TI - Stereotactic laser ablation as treatment for brain metastases that recur after stereotactic radiosurgery: a multiinstitutional experience. AB - OBJECTIVE Therapeutic options for brain metastases (BMs) that recur after stereotactic radiosurgery (SRS) remain limited. METHODS The authors provide the collective experience of 4 institutions where treatment of BMs that recurred after SRS was performed with stereotactic laser ablation (SLA). RESULTS Twenty six BMs (in 23 patients) that recurred after SRS were treated with SLA (2 patients each underwent 2 SLAs for separate lesions, and a third underwent 2 serial SLAs for discrete BMs). Histological findings in the BMs treated included the following: breast (n = 6); lung (n = 6); melanoma (n = 5); colon (n = 2); ovarian (n = 1); bladder (n = 1); esophageal (n = 1); and sarcoma (n = 1). With a median follow-up duration of 141 days (range 64-794 days), 9 of the SLA-treated BMs progressed despite treatment (35%). All cases of progression occurred in BMs in which < 80% ablation was achieved, whereas no disease progression was observed in BMs in which >= 80% ablation was achieved. Five BMs were treated with SLA, followed 1 month later by adjuvant SRS (5 Gy daily * 5 days). No disease progression was observed in these patients despite ablation efficiency of < 80%, suggesting that adjuvant hypofractionated SRS enhances the efficacy of SLA. Of the 23 SLA-treated patients, 3 suffered transient hemiparesis (13%), 1 developed hydrocephalus requiring temporary ventricular drainage (4%), and 1 patient who underwent SLA of a 28.9-cm3 lesion suffered a neurological deficit requiring an emergency hemicraniectomy (4%). Although there is significant heterogeneity in corticosteroid treatment post-SLA, most patients underwent a 2-week taper. CONCLUSIONS Stereotactic laser ablation is an effective treatment option for BMs in which SRS fails. Ablation of >= 80% of BMs is associated with decreased risk of disease progression. The efficacy of SLA in this setting may be augmented by adjuvant hypofractionated SRS. PMID- 27690655 TI - Percutaneous surgery for treatment of epidural spinal cord compression and spinal instability: technical note. AB - OBJECTIVE An emerging paradigm for treating patients with epidural spinal cord compression (ESCC) caused by metastatic tumors is surgical decompression and stabilization, followed by stereotactic radiosurgery. In the setting of rapid progressive disease, interruption or delay in return to systemic treatment can lead to a negative impact in overall survival. To overcome this limitation, the authors introduce the use of spinal laser interstitial thermotherapy (sLITT) in association with percutaneous spinal stabilization to facilitate a rapid return to oncological treatment. METHODS The authors retrospectively reviewed a consecutive series of patients with ESCC and spinal instability who were considered to be poor surgical candidates and instead were treated with sLITT and percutaneous spinal stabilization. Demographic data, Spine Instability Neoplastic Scale score, degree of epidural compression before and after the procedure, length of hospital stay, and time to return to oncological treatment were analyzed. RESULTS Eight patients were treated with thermal ablation and percutaneous spinal stabilization. The primary tumors included melanoma (n = 3), lung (n = 3), thyroid (n = 1), and renal cell carcinoma (n = 1). The median Karnofsky Performance Scale score before and after the procedure was 60, and the median hospital stay was 5 days (range 3-18 days). The median Spine Instability Neoplastic Scale score was 13 (range 12-16). The mean modified postoperative ESCC score (2.75 +/- 0.37) was significantly lower than the preoperative score (4.5 +/ 0.27) (Mann-Whitney test, p = 0.0044). The median time to return to oncological treatment was 5 days (range 3-10 days). CONCLUSIONS The authors present the first cohort of sLITT associated with a percutaneous spinal stabilization for the treatment of ESCC and spinal instability. This minimally invasive technique can allow a faster recovery without prejudice of adjuvant systemic treatment, with adequate local control and spinal stabilization. PMID- 27690656 TI - Stereotactic laser ablation for hypothalamic and deep intraventricular lesions. AB - OBJECTIVE Laser ablation is a novel, minimally invasive procedure that utilizes MRI-guided thermal energy to treat epileptogenic and other brain lesions. In addition to treatment of mesial temporal lobe epilepsy, laser ablation is increasingly being used to target deep or inoperable lesions, including hypothalamic hamartoma (HH), subependymal giant cell astrocytoma (SEGA), and exophytic intrinsic hypothalamic/third ventricular tumors. The authors reviewed their early institutional experience with these patients to characterize clinical outcomes in patients undergoing this procedure. METHODS A retrospective cohort (n = 12) of patients undergoing laser ablation at a single institution was identified, and clinical and radiographic records were reviewed. RESULTS Laser ablation was successfully performed in all patients. No permanent neurological or endocrine complications occurred; 2 (17%) patients developed acute obstructive hydrocephalus or shunt malfunction following treatment. Laser ablation of HH resulted in seizure freedom (Engel Class I) in 67%, with the remaining patients having a clinically significant reduction in seizure frequency of greater than 90% compared with preoperative baseline (Engel Class IIB). Treatment of SEGAs resulted in durable clinical and radiographic tumor control in 2 of 3 cases, with one patient receiving adjuvant everolimus and the other receiving no additional therapy. Palliative ablation of hypothalamic/third ventricular tumors resulted in partial tumor control in 1 of 3 patients. CONCLUSIONS Early experience suggests that laser ablation is a generally safe, durable, and effective treatment for patients harboring HHs. It also appears effective for local control of SEGAs, especially in combination therapy with everolimus. Its use as a palliative treatment for intrinsic hypothalamic/deep intraventricular tumors was less successful and associated with a higher risk of serious complications. Additional experience and long-term follow-up will be beneficial in further characterizing the effectiveness and risk profile of laser ablation in treating these lesions in comparison with conventional resective surgery or stereotactic radiosurgery. PMID- 27690657 TI - Laser interstitial thermal therapy for newly diagnosed and recurrent glioblastoma. AB - OBJECTIVE Glioblastoma (GBM) is the most common and deadly malignant primary brain tumor. Better surgical therapies are needed for newly diagnosed GBMs that are difficult to resect and for GBMs that recur despite standard therapies. The authors reviewed their institutional experience of using laser interstitial thermal therapy (LITT) for the treatment of newly diagnosed or recurrent GBMs. METHODS This study reports on the pre-LITT characteristics and post-LITT outcomes of 8 patients with newly diagnosed GBMs and 13 patients with recurrent GBM who underwent LITT. RESULTS Compared with the group with recurrent GBMs, the patients with newly diagnosed GBMs who underwent LITT tended to be older (60.8 vs 48.9 years), harbored larger tumors (22.4 vs 14.6 cm3), and a greater proportion had IDH wild-type GBMs. In the newly diagnosed GBM group, the median progression-free survival and the median survival after the procedure were 2 months and 8 months, respectively, and no patient demonstrated radiographic shrinkage of the tumor on follow-up imaging. In the 13 patients with recurrent GBM, 5 demonstrated a response to LITT, with radiographic shrinkage of the tumor following ablation. The median progression-free survival was 5 months, and the median survival was greater than 7 months. CONCLUSIONS In carefully selected patients with recurrent GBM, LITT may be an effective alternative to surgery as a salvage treatment. Its role in the treatment of newly diagnosed unresectable GBMs is not established yet and requires further study. PMID- 27690658 TI - Laser interstitial thermal therapy followed by minimal-access transsulcal resection for the treatment of large and difficult to access brain tumors. AB - OBJECTIVE Laser interstitial thermal therapy (LITT), sometimes referred to as "stereotactic laser ablation," has demonstrated utility in a subset of high-risk surgical patients with difficult to access (DTA) intracranial neoplasms. However, the treatment of tumors larger than 10 cm3 is associated with suboptimal outcomes and morbidity. This may limit the utility of LITT in dealing with precisely those large or deep tumors that are most difficult to treat with conventional approaches. Recently, several groups have reported on minimally invasive transsulcal approaches utilizing tubular retracting systems. However, these approaches have been primarily used for intraventricular or paraventricular lesions, and subtotal resections have been reported for intraparenchymal lesions. Here, the authors describe a combined approach of LITT followed by minimally invasive transsulcal resection for large and DTA tumors. METHODS The authors retrospectively reviewed the results of LITT immediately followed by minimally invasive, transsulcal, transportal resection in 10 consecutive patients with unilateral, DTA malignant tumors > 10 cm3. The patients, 5 males and 5 females, had a median age of 65 years. Eight patients had glioblastoma multiforme (GBM), 1 had a previously treated GBM with radiation necrosis, and 1 had a melanoma brain metastasis. The median tumor volume treated was 38.0 cm3. RESULTS The median tumor volume treated to the yellow thermal dose threshold (TDT) line was 83% (range 76%-92%), the median tumor volume treated to the blue TDT line was 73% (range 60%-87%), and the median extent of resection was 93% (range 84%-100%). Two patients suffered mild postoperative neurological deficits, one transiently. Four patients have died since this analysis and 6 remain alive. Median progression free survival was 280 days, and median overall survival was 482 days. CONCLUSIONS Laser interstitial thermal therapy followed by minimally invasive transsulcal resection, reported here for the first time, is a novel option for patients with large, DTA, malignant brain neoplasms. There were no unexpected neurological complications in this series, and operative characteristics improved as surgeon experience increased. Further studies are needed to elucidate any differences in survival or quality of life metrics. PMID- 27690660 TI - Stereotactic robot-assisted MRI-guided laser thermal ablation of radiation necrosis in the posterior cranial fossa: technical note. AB - Laser interstitial thermal therapy (LITT) is a minimally invasive procedure used to treat a variety of intracranial lesions. Utilization of robotic assistance with stereotactic procedures has gained attention due to potential for advantages over conventional techniques. The authors report the first case in which robot assisted MRI-guided LITT was used to treat radiation necrosis in the posterior fossa, specifically within the cerebellar peduncle. The use of a stereotactic robot allowed the surgeon to perform LITT using a trajectory that would be extremely difficult with conventional arc-based techniques. A 60-year-old man presented with facial weakness and brainstem symptoms consistent with radiation necrosis. He had a history of anaplastic astrocytoma that was treated with CyberKnife radiosurgery 1 year prior to presentation, and he did well for 11 months until his symptoms recurred. The location and form of the lesion precluded excision but made the patient a suitable candidate for LITT. The location and configuration of the lesion required a trajectory for LITT that was too low for arc-based stereotactic navigation, and thus the ROSA robot (Medtech) was used. Using preoperative MRI acquisitions, the lesion in the posterior fossa was targeted. Bone fiducials were used to improve accuracy in registration, and the authors obtained an intraoperative CT image that was then fused with the MR image by the ROSA robot. They placed the laser applicator and then ablated the lesion under real-time MR thermometry. There were no complications, and the patient tolerated the procedure well. Postoperative 2-month MRI showed complete resolution of the lesion, and the patient had some improvement in symptoms. PMID- 27690659 TI - Intracerebral laser interstitial thermal therapy followed by tumor resection to minimize cerebral edema. AB - OBJECTIVE Laser interstitial thermal therapy (LITT) is used in numerous neurosurgical applications including lesions that are difficult to resect. Its rising popularity can be attributed to its minimally invasive approach, improved accuracy with real-time MRI guidance and thermography, and enhanced control of the laser. One of its drawbacks is the possible development of significant edema, which contributes to extended hospital stays and often necessitates hyperosmolar or steroid therapy. Here, the authors discuss the use of minimally invasive craniotomy to resect tissue ablated with LITT in attempt to minimize cerebral edema. METHODS Five patients with glioblastoma multiforme prospectively underwent LITT followed by resection. The LITT was performed with the aid of an MR compatible skull-mounted frame in the MRI suite. Ablated tumor was then resected via small craniotomy by using the NICO Myriad system or cavitron ultrasonic surgical aspirator. Postoperative management involved dexamethasone administration slowly tapered over several weeks. RESULTS The use of resection following LITT, as compared with open resection or LITT alone, did not extend the hospital stay except in 1 patient who required 3-day inpatient management of edema with a trapped ventricle. No new neurological deficits were encountered, although 1 patient developed seizures postoperatively. No increase in infection rates was identified. CONCLUSIONS Resection of ablated tumor is a viable option to reduce the incidence of neurological deficits due to edema following LITT. This approach appears to mitigate cerebral edema by increasing available volume for mass effect and reducing the tissue burden that may promote an inflammatory response. PMID- 27690661 TI - Putting the Fear Back Again (and Within Individuals): Revisiting the Role of Fear in Persuasion. AB - The overwhelming majority of fear appeal research came from the between individuals approach and yielded consistent evidence for a linear fear-persuasion relationship. A recent review suggested that the within-individuals approach might be more appropriate. Studies that measured fear at multiple time points have consistently revealed a curvilinear association between fear and persuasion predicted by the drive model. A Web-based experiment (N = 454) using tobacco warning labels was conducted to replicate the inverted-U shape curvilinear relationship between fear and persuasion, and to revisit the role of fear in fear appeal theories. Results showed that the inverted-U fear curve positively predicted persuasion and reduced maladaptive responses, and that the linear trajectory of fear positively predicted maladaptive responses and failure of persuasion. PMID- 27690662 TI - Titanium-nitride-oxide-coated coronary stents: insights from the available evidence. AB - Coating of stent surface with a biocompatible material is suggested to improve stent safety profile. A proprietary process was developed to coat titanium nitride-oxide on the stent surface, based on plasma technology that uses the nano synthesis of gas and metal. Preclinical in vitro and in vivo investigation confirmed blood compatibility of titanium (nitride-) oxide films. Titanium nitride-oxide-coated stents demonstrated a better angiographic outcome, compared with bare-metal stents at mid-term follow-up; however, they failed to achieve non inferiority for angiographic outcome versus second-generation drug-eluting stents. Observational studies showed adequate clinical outcome at mid-term follow up. Non-randomized studies showed an outcome of titanium-nitride-oxide-coated stents comparable to - or better than - first-generation drug-eluting stents at long-term follow-up. Two randomized controlled trials demonstrated comparable efficacy outcome, and a better safety outcome of titanium-nitride-oxide-coated stents versus drug-eluting stents at long-term follow-up. Evaluation by optical coherence tomography at mid-term follow-up revealed better neointimal strut coverage associated with titanium-nitride-oxide-coated stents versus drug-eluting stents; yet, neointimal hyperplasia thickness was greater. Key messages Stents coated with titanium-nitride-oxide demonstrated biocompatibility in preclinical studies: they inhibit platelet and fibrin deposition, and reduce neointimal growth. In observational and non-randomized studies, titanium-nitride-oxide coated stents were associated with adequate safety and efficacy outcome. In randomized trials of patients with acute coronary syndrome, titanium-nitride oxide-coated stents were associated with a better safety outcome, compared with drug-eluting stents; efficacy outcome was comparable. PMID- 27690663 TI - Pharmacological treatment of children and adolescents with depression. AB - INTRODUCTION: Despite an increasing number of studies, there is debate whether antidepressants have a favorable benefit/risk balance in depressed youth. Areas covered: A systematic search identified 23 systematic reviews and meta-analyses published between 2010-2016. More than 30 controlled clinical trials were conducted in adolescents, but only a few in pre-pubertal patients. About one third of the trials were severely statistically underpowered. Most studies failed to detect differences from placebo, but a few found fluoxetine effective. Although no suicide occurred in these studies, antidepressants increased suicidality risk (including suicidal ideation and behavior) versus placebo (OR = 2.39). Only two placebo-controlled trials with acceptable statistical power were publicly funded: both showed efficacy of fluoxetine, and one found a higher incidence of suicidality (OR = 3.7, 95% C.I. 1.00-13.7). Expert opinion: In youth, antidepressants have, on average, a small therapeutic effect. The high placebo response is exacerbated by the large number of sites in many industry funded studies. There is evidence that fluoxetine leads to greater and faster improvement than placebo or psychotherapy in adolescents. Considering both the high response to non-specific interventions and safety concerns, antidepressants should be used cautiously in youth, and limited to patients with moderate-to severe depression for whom psychosocial interventions are either ineffective or not feasible. PMID- 27690664 TI - Emerging growth factor receptor antagonists for the treatment of renal cell carcinoma. AB - INTRODUCTION: The landscape of systemic treatment for metastatic renal cell carcinoma (RCC) has dramatically changed with the introduction of targeted agents including vascular endothelial growth factor (VEGF) inhibitors. Recently, multiple new agents including growth factor receptor antagonists and a checkpoint inhibitor were approved for the treatment of refractory metastatic RCC based on encouraging benefit shown in clinical trials. Areas covered: The background and biological rationale of existing treatment options including a brief discussion of clinical trials which led to their approval, is presented. This is followed by reviewing the limitations of these therapeutic options, medical need to develop new treatments and major goals of ongoing research. We then discuss two recently approved growth factor receptor antagonists i.e. cabozantinib and lenvatinib, and a recently approved checkpoint inhibitor, nivolumab, and issues pertaining to drug development, and future directions in treatment of metastatic RCC. Expert opinion: Recently approved growth factor receptor antagonists have shown encouraging survival benefit but associated drug toxicity is a major issue. Nivolumab, a programmed death 1 (PD-1) checkpoint inhibitor, has similarly shown survival benefit and is well tolerated. With multiple options now available in this patient population, the right sequence of these agents remains to be determined. PMID- 27690665 TI - Chemical JAK inhibitors for the treatment of rheumatoid arthritis. AB - INTRODUCTION: Considerable advances in the treatment of rheumatoid arthritis (RA) have been made following the advent of biological disease-modifying anti rheumatic drugs (DMARDs). However, biological DMARDs require intravenous or subcutaneous injection and some patients fail to respond to these drugs or lose their primary response. Currently, Janus kinase (JAK) inhibitors have been developed as a new class of DMARD that inhibits the non-receptor tyrosine kinase family JAK involved in intracellular signaling of various cytokines and growth factors. Area covered: Several JAK inhibitors such as tofacitinib and baricitinib are oral synthetic DMARD that inhibit JAK1, 2 and 3. Both drugs have shown feasible efficacy and tolerable safety. In this article, efficacy and adverse events from the phase III trials of JAK inhibitors are overviewed. In addition, pharmacokinetics and mechanism of action of JAK inhibitors in relevance to efficacy and adverse events are covered. Expert opinion: JAK inhibitors are novel therapies for RA that inhibit multiple cytokines and signaling pathways. Further studies are needed to determine their risk-benefit ratio and selection of the most appropriate patients for such therapy. PMID- 27690666 TI - Do oral contraceptives increase epileptic seizures? AB - INTRODUCTION: Hormonal contraceptives are used by over 100 million people worldwide. Recently, there has been an emerging interest in studying the potential impact of oral contraceptives (OCs) on certain neurological conditions. It has been suspected for some time that hormonal birth control increases seizure activity in women with epilepsy, but there is little supportive data. Areas covered: Literature from PubMed and online sources was analyzed with respect to hormonal contraception and epilepsy or seizures. New evidence indicates that OCs can cause an increase in seizures in women with epilepsy. The epilepsy birth control registry, which surveyed women with epilepsy, found that those using hormonal contraceptives self-reported 4.5 times more seizures than those that did not use such contraceptives. A preclinical study confirmed these outcomes wherein epileptic animals given ethinyl estradiol, the primary component of OCs, had more frequent seizures that are more likely to be resistant. Expert commentary: OC pills may increase seizures in women with epilepsy and such refractory seizures are more likely to cause neuronal damage in the brain. Thus, women of child bearing age with epilepsy should consider using non-hormonal forms of birth control to avoid risks from OC pills. Additional research into the mechanisms and prospective clinical investigation are needed. PMID- 27690667 TI - Pharmacodynamics, pharmacokinetics and clinical efficacy of phosphodiesterase-5 inhibitors. AB - INTRODUCTION: Phosphodiesterase type 5 inhibitors (PDE5Is) are the first-line drugs in the management of erectile dysfunction (ED). However, over the past two decades tremendous efforts have been made to identify new clinical uses of PDE5Is beyond their roles in ED. Areas covered: Basic science articles, clinical trials, reviews, and meta-analysis published between 1996 and 2015 were searched using MEDLINE (PubMed interface) to collect the most relevant and impactful studies from our perspectives as practicing urologists. This review mainly focuses on the level one evidence-based clinical efficacy and drug-related toxicity of oral PDE5Is. In addition, drug discovery, pharmacokinetics and pharmacodynamics, potential use in other diseases, and future directions are discussed. Expert opinion: On-demand PED5Is for the treatment of ED has shifted toward chronic administration in a broad spectrum of conditions that are thought to be associated with endovascular health. Several studies have shown that PDE5Is may play a cardioprotective or neuroprotective role. Further studies are under way to verify beneficial effects of PDE5I in non-urological conditions.

PMID- 27690670 TI - STARTING ARIPIPRAZOLE LONG-ACTING-ONCE-A-MONTH EARLY IN TREATMENT: WHY, HOW AND FOR WHOM? EXPERT CONSENSUS AND PRACTICAL RECOMMENDATIONS BY A PANEL OF ITALIAN CLINICIANS. AB - INTRODUCTION: Aripiprazole long acting once-monthly (AOM) is approved for the treatment of schizophrenia in adults. Despite recent evidence of AOM efficacy in the acute treatment of schizophrenia, it is recommended that AOM should be started once the acute symptoms are controlled and patients are stabilized. However, there currently are no definitive guidelines exactly describing when a patient is to be considered stabilized enough to start AOM and which the patients are for whom an early AOM start is to be preferred. AREAS COVERED: A panel of Italian clinicians experienced with real world use of AOM met to discuss the scenarios where an early (i.e., immediately after controlling the acute symptoms) start of AOM may be suggested. Real life clinical experiences were shared and a consensus was reached. EXPERT OPINION: There are cases when the risks/benefits ratio suggests to start AOM early, i.e. immediately after the acute symptoms have been stabilized, as opposed to starting it several days/weeks after the stabilization of acute symptoms. Clinical pearls, guidelines and opinions are provided. PMID- 27690669 TI - Ixekizumab for treatment of adults with moderate-to-severe plaque psoriasis and psoriatic arthritis. AB - INTRODUCTION: The interleukin (IL)-17 family of cytokines has emerged as an important pro-inflammatory mediator of psoriasis and psoriatic arthritis (PsA). Ixekizumab is an IL17A inhibitor that has been approved for the treatment of chronic plaque psoriasis. Phase III studies of ixekizumab in treating of PsA demonstrated promise by minimizing disease severity and progression. Areas covered: This review focuses on the biologic properties, pharmacokinetics and key clinical trial results that demonstrated the safety and efficacy of ixekizumab in treating psoriatic disease. Expert commentary: Ixekizumab is a biologic that has been approved for the treatment of chronic plaque psoriasis. With respect to safety, ixekizumab is generally well tolerated with injection-site reactions, nasopharyngitis, and upper respiratory tract infections being the most common adverse events. Most patients with anti-drug antibodies have low antibody titer levels resulting in no meaningful interference in clinical response to ixekizumab. PMID- 27690671 TI - Peptides as a therapeutic avenue for nanocarrier-aided targeting of glioma. AB - INTRODUCTION: Very few successful interventions have been possible in glioma therapy owing to its aggressive nature as well as its hindrance of targeted therapy together with the limited access afforded by the blood-brain barrier (BBB). With the advent of nanotechnology based delivery vehicles such as micelles, dendrimers, polymer-based nanoparticles and nanogels, the breach of the BBB has been facilitated. However, there remains the issue of targeted therapy for glioma cells. Peptide-mediated surface modification of nanocarriers serves this purpose, extending the ability to target glioma further than the enhanced permeability and retention effect. Areas covered: Here we have tried to re establish the significance of peptides that could be used in various ways for treating glioma. Peptide-embellished nanocarriers used to deliver anticancer drugs; nucleic acids (siRNA, miRNA); micelles or dendrimers grafted with immunogenic glioma-derived peptides used for stimulating active immunity in vaccine therapy, glioma targets for cell penetrating peptides and homing to specific receptors are reviewed. Expert opinion: Peptides have multifunctional potential in targeting, BBB and cell penetration, and can serve as antagonists of various ligands and agonists of particular over-expressed receptors as discussed in this review. Using peptides in targeted personalized therapy would be one step forward and may offer new avenues for glioma therapeutics. PMID- 27690672 TI - Myasthenia gravis: recent advances in immunopathology and therapy. AB - INTRODUCTION: Myasthenia gravis is the most frequent acquired disorder of neuromuscular transmission. In the majority of cases, pathogenic antibodies against components of the postsynaptic muscle endplate membrane can be detected. In recent years there have been significant advances in the pathophysiological understanding and therapy of the disease. Areas covered: PubMed searches were conducted for the term 'myasthenia gravis' cross-referenced with the terms 'immunology', 'subgroups', 'antibody', 'ocular', 'thymoma', 'treatment' and 'thymectomy'. Additionally, we summarized the current state of immunopathology and therapy. Expert commentary: Immunological research defined new target antigens at the postsynaptic neuromuscular junction which along with clinical features allow a refined definition of disease subgroups. Overall the prognosis of myasthenia gravis with best possible symptomatic, immunosuppressive and supportive treatment is good but new immunomodulatory treatment options are developed for patients who do not respond well to the first line therapy. For most patients individually adapted long-term drug therapy is needed. PMID- 27690673 TI - Systemic inflammatory immune signatures in a patient with CRB1 linked retinal dystrophy. AB - BACKGROUND: In this report we describe, for the first time, the activation of the peripheral immune compartment in a patient with a CRB1 linked retinal degenerative disease, masquerading as intermediate uveitis. METHODS: To monitor the immune system during systemic immunosuppressive treatment, given for the initial diagnosis of intermediate uveitis, blood samples were taken before and during therapy, for analysis of peripheral blood mononuclear cell-subsets and circulating immune mediators. RESULTS: The levels of various pro-inflammatory immune mediators (including MIF, TSLP, CCL2/MCP-1, CXCL9, CXCL10, IFN-beta, IL-6, IL-17, IL-21, IL-22, and IL-23) were elevated in serum at the first time point, and decreased under immunosuppressive treatment. In parallel, the frequency of activated (CD86+) CD1c+ myeloid dendritic cells in blood was proportional to the central foveal thickness measured by optical coherence tomography. CONCLUSIONS: These observations challenge the current view on the distinct pathophysiology of retinal degenerative and retinal inflammatory conditions in this patient.

AB - INTRODUCTION: Implantable loop recorders (ILRs) have become an important pillar in the diagnostic work-up of patients with unexplained syncope. Areas covered: The modern ILR is minimally-invasive and provides an extended-duration of monitoring with high diagnostic yield. These insertable cardiac monitors (ICMs) enable prolonged monitoring that extends the opportunity for symptom-rhythm correlation from days-weeks to years, with associated incremental diagnostic yield. Over the years, observational studies and randomized trials have supported a unique role for ILRs in the assessment of recurrent or high-risk unexplained syncope. Furthermore, ILRs have been used in the elderly, in children, patients with overt heart disease, and patients with conduction block with varying success. The current guidelines recommend ILRs in the early phase of evaluation in recurrent syncope, and as part of the comprehensive evaluation of high-risk patients with syncope. Expert commentary: In this review, we discuss the evidence surrounding ILRs, including comparison studies with 'conventional' management and the external loop recorder.

PMID- 27690678 TI - Targeted therapies: what they teach us about the pathogenesis of psoriasis and psoriatic arthritis. AB - INTRODUCTION: Biologic therapy has revolutionized treatment pathways in psoriatic joint and skin disease. It has also provided a useful tool with which pathological pathways of this condition may be explored. Areas covered: This review presents data on the clinical and biological effects of targeted therapy in psoriatic arthritis and psoriasis. Therapeutic agents covered include inhibitors of TNFalpha, inhibitors of the IL-23/IL-17 axis and inhibitors of intracellular small molecules involved in the transduction of the inflammatory signal. Trial data on clinical and imaging efficacy is reviewed in parallel with studies on biological effects at tissue level. Pathological insights gained from the use of these treatments are explored. Expert commentary: A close relationship exists between specific pathological types and clinical manifestations of psoriatic disease, including responses to treatment. Studying these relationships is likely to improve understanding of disease and enable rational selection of specific treatments for patients with specific pathotypes. PMID- 27690679 TI - Recent advances in the management of juvenile systemic sclerosis. AB - INTRODUCTION: Juvenile Systemic Sclerosis (JSSc) is one of the most severe multi systemic connective tissue conditions encountered in pediatric rheumatology. Due to its high morbidity and mortality rate, early diagnosis, proper assessment and effective treatment are crucial. Areas covered: In this review, we will focus on the recent advances on the classification and general management of JSSc based on the literature search and on the Authors' experience. Expert commentary: Classification criteria for the pediatric forms of systemic sclerosis, the new proposed assessment tools, such as the juvenile systemic sclerosis severity score, named J4S, and new techniques for the internal organs assessment, will facilitate both daily practice and research projects. Unfortunately, no known drugs seem to be effective in preventing the development of disease complications although a few treatments, undertaken according to experience in adults, have shown some effects in arresting the disease progression. PMID- 27690680 TI - Neratinib for the treatment of breast cancer. AB - INTRODUCTION: Neratinib is an orally available, pan-HER inhibitor with clinical activity in patients with HER2-amplified and HER2-mutated breast cancer. Areas Covered. A summary of publically available and relevant clinical data on neratinib. Expert Opinion. Neratinib (N) is clearly distinct from lapatinib (L), a difference based on its broad anti-HER effect, its covalent target binding and its toxicity profile. The main toxicity of neratinib is gastro-intestinal and is essentially limited to diarrhea. Although not directly compared with single agent lapatinib, skin toxicity is much less pronounced with N. The direct clinical comparison of N-capecitabine versus L-capecitabine is the subject of the ongoing NALA-trial. In patients with advanced disease, neratinib has clinically relevant activity in patients with trastuzumab(T)-pretreated and unpretreated disease. In patients having completed one year of adjuvant trastuzumab, an additional year of neratinib further reduces the risk of recurrence of invasive disease. The activity of neratinib in HER2-mutated advanced disease is subject of ongoing clinical trials but preclinical and early clinical results are promising. Neratinib is a usefull drug and a valuable addition to the different anti-HER2 drugs avalaible for patients with HER2-overexpressing and HER2-mutated breast cancer. PMID- 27690681 TI - Magnetic silica nanocomposites for magnetic hyperthermia applications. AB - This paper summarizes nearly all magnetic silica nanocomposites that have been synthesized for biomedical applications and evaluated under alternating magnetic field (AMF) from the point of view of heat generation. The use of these nanocomposites as a drug delivery system for remote control of drug release via applying AMF is described. Different parameters that affect the magnetic properties and therefore affect the amount of generated heat and the fact that sometimes these parameters are in conflict with each other are discussed. This review article presents insight into the synthesis of nanocomposites with optimal characteristics and use of them in optimal conditions to achieve the optimal magnetic properties for magnetic hyperthermia. PMID- 27690682 TI - Impact of nitroglycerin and glucagon administration on selective common bile duct cannulation and prevention of post-ERCP pancreatitis. AB - OBJECTIVE: Easy common bile duct (CBD) cannulation is associated with low complication rate. This study aimed to investigate the potential impact of nitroglycerin and glucagon administration on selective CBD cannulation and prevention of post-ERCP pancreatitis. METHODS: A prospective single center, double-blind randomized study in which a total of 455 patients were randomly assigned to CBD cannulation by receiving 6 puffs (2.4 mg) sublingual nitroglycerin and glucagon 1 mg intravenously (n = 227, group A) or 6 puffs sterile water and 20 mg hyoscine-n-butyl bromide intravenously (n = 228, group B). After ERCP, patients were followed for the development of drugs' side-effects and post-ERCP complications. RESULTS: There were no statistically significant differences between the two groups regarding demographic data and ERCP findings. Success rate of selective CBetaD cannulation was 95.15% in group A versus 82.29% in group B (p < .001). Time required for CBD cannulation was 2.82 +/- 2.31 min in group A versus 4.27 +/- 3.84 min in group B (p = .021). Needle-knife papillotomy was used in 11 (4.85%) patients of group A and 39 (17.11%) patients of group B (p = .001). The frequency of post-ERCP pancreatitis was significantly lower in group A than in group B (3.08% versus 7.46%, p = .037). No difference was observed between the two groups with regard to the occurrence of post-procedure hemorrhage. There was no procedure-related mortality; no adverse event related to the combination regimen was observed. CONCLUSIONS: Combined nitroglycerin and glucagon administration achieves a high selective CBC cannulation rates with concomitant reduction of post-ERCP pancreatitis incidence. However, further relative large-scale studies are needed to confirm our findings before definite conclusions can be drawn (Clinical trial registration number: NT: 4321). PMID- 27690683 TI - Cytomegalovirus in hematopoietic stem cell transplant recipients - management of infection. AB - INTRODUCTION: Cytomegalovirus (CMV) still causes significant morbidity and mortality in patients given allogeneic hematopoietic stem cell transplantation (HSCT). Despite effective pharmacotherapy, potentially life-threatening CMV disease occurs nowadays in up to 10% of HSCT recipients; moreover, routinely used anti-CMV agents have been shown to be associated with morbidity. Areas covered: This review examines different issues related to diagnosis and management of CMV infection in HSCT recipients, paying particular attention to the monitoring of CMV-specific immune recovery, approaches of adoptive cell therapy and new antiviral drugs. Expert commentary: Despite advances in diagnostic tests and treatment, there is still room for refining management of CMV in HSCT recipients. Immunological monitoring should be associated in the future to virological monitoring. The safety profile and efficacy of new anti-CMV agents should be compared with that of standard-of-care drugs. Donor-derived, pathogen-specific T cells adoptively transferred after transplantation could contribute to reduce the impact of CMV infection on patient's outcome. PMID- 27690684 TI - Novel adipokines WISP1 and betatrophin in PCOS: relationship to AMH levels, atherogenic and metabolic profile. AB - OBJECTIVE: To determine the levels of WISP1 and betatrophin in normal weight and obese women with polycystic ovary syndrome (PCOS) and to assess their relationship with anti-Mullerian hormone (AMH) levels, atherogenic profile and metabolic parameters Methods: In this prospective cross-sectional study, the study group was composed of 49 normal weighed and 34 obese women with PCOS diagnosed based on the Rotterdam criteria; 36 normal weight and 26 obese age matched non-hyperandrogenemic women with regular menstrual cycle. Serum WISP1, betatrophin, homeostasis model assessment of insulin resistance (HOMA-IR) and AMH levels were evaluated. Univariate and multivariate analyses were performed between betatrophin, WISP1 levels and AMH levels, metabolic and atherogenic parameters. RESULTS: Serum WISP1 and betatrophin values were elevated in the PCOS group than in the control group. Moreover, serum WISP1 and betatrophin levels were higher in the obese PCOS subgroup than in normal weight and obese control subgroups. Multivariate analyses revealed that Body mass index, HOMA-IR, AMH independently and positively predicted WISP1 levels. Serum betatrophin level variability was explained by homocysteine, HOMA-IR and androstenedione levels. CONCLUSION: WISP1 and betatrophin may play a key role on the pathogenesis of PCOS. PMID- 27690685 TI - Transanal total mesorectal excision for rectal cancer: The journey towards a new technique and its current status. AB - INTRODUCTION: The surgical approach to total mesorectal excision (TME) for rectal cancer has undergone a substantial evolution with the adoption of more minimally invasive procedures. Transanal TME (taTME) is the latest advanced technique pioneered to tackle difficult pelvic dissections. Areas covered: The evolution of TME surgery from open to laparoscopic, robotic and transanal techniques was explored in this review. The outcomes to date on the latest approach, taTME, are reviewed and the future direction of rectal cancer surgery proposed. A literature search was performed using Embase, Medline, Web of Science and Cochrane databases for articles published between January 2005 to May 2016 using the keywords "transanal", "TME", "laparoscopy", "robotics", "minimally invasive", "outcomes" and "training". Expert Commentary: Surgical experience in taTME is growing and randomised controlled trials have been planned and initiated worldwide. However, the learning curve for this procedure remains to be established and a structured training programme is necessary to ensure safe introduction and dissemination of the technique in the clinical setting. Further innovation including stereotactic navigation and more specialised transanal equipment are currently being explored and are likely to enhance the technique further. PMID- 27690686 TI - Vaccines for piscirickettsiosis (salmonid rickettsial septicaemia, SRS): the Chile perspective. AB - INTRODUCTION: Piscirickettsia salmonis (P. salmonis) is the aetiological bacterium of the contagious disease piscirickettsiosis or salmonid rickettsial septicaemia (SRS) and causes significant economic losses to aquaculture production in Chile. Current strategies to control infection are i) indiscriminate antibiotic use and ii) vaccination with predominantly P. salmonis bacterin vaccines that do not provide acceptable levels of protection against piscirickettsiosis. Areas covered: This review covers the basic biology of P. salmonis, clinical piscirickettsiosis and disease control, the development of current P. salmonis vaccines, innate and adaptive immunity and a 5-year plan to develop new piscirickettsiosis vaccines. Expert commentary: Fundamental knowledge is lacking on the complexities of P. salmonis-host interactions, relating to bacterial virulence and host innate and adaptive immune responses, which needs to be addressed. The development of new P. salmonis vaccines needs the application of comprehensive 'omics' technologies to identify candidate vaccine antigens capable of stimulating long-lasting protective immune responses. PMID- 27690687 TI - A comparison between the effects of metformin and megestrol on simple endometrial hyperplasia. AB - INTRODUCTION: Endometrial hyperplasia is one of the most serious causes of severe abnormal bleeding and also can be a precursor of endometrial carcinoma. OBJECTIVE: The purpose of the present study was to compare the effects of metformin and megestrol on the endometrial hyperplasia. METHODS: The study was performed as a randomized clinical trial on 42 cases of histopathologically confirmed simple endometrial hyperplasia without atypia. The eligible women were randomly assigned into two groups. In metformin group, metformin was prescribed, 500 mg twice a day (1000 mg daily), for a duration of 4 weeks, and then, followed by 1500 mg daily, for 8 more weeks. In the megestrol group, megestrol was prescribed 40 mg daily for 12 weeks. At the end of the duration of the treatment, endometrial sampling was performed and the results were compared between the two groups. RESULTS: The women of the two groups did not have significant difference according to age, BMI and gravidity, parity and history of abortion. Overall, 18 women (81.8%) in metformin group and 12 women (60%) in the megestrol group had normal endometrial histology, after 12 weeks of treatment (p = 0.11). CONCLUSION: Metformin is comparable with megestrol for the treatment of simple endometrial hyperplasia. PMID- 27690689 TI - Ceftobiprole medocaril (BAL-5788) for the treatment of complicated skin infections. AB - INTRODUCTION: With resistance of S. aureus, the most prevalent identified pathogen in skin and soft tissue infections, on the rise, the need for safe, effective, and well-tolerated antibiotics is crucial. Ceftobiprole medocaril (BAL 5788), ceftobiprole's parenteral prodrug, is a bactericidal cephalosporin with broad Gram-positive and Gram-negative activity that has shown to be well tolerated and noninferior to vancomycin and vancomycin plus ceftazidime in the treatment of MRSA complicated skin and skin structure infections (cSSSIs) in clinical trials. Areas Covered: This article overviews ceftobiprole medocaril's use for cSSSI, with specific focus on clinical efficacy and safety data in addition to summary information on its basic chemistry, microbiological profile, and pharmacokinetic/pharmacodynamic relationships supporting its use in cSSSIs. Information sources include peer-reviewed scientific literature, conference proceedings, publically available regulatory reports, as well as information from the drug sponsor's website. Expert Commentary: With increasing antibiotic resistance, safe, effective antibiotics agents are a welcome sight. There has been clinical evidence in support of using ceftobiprole for treatment of Gram positive and -negative infections, including MRSA and susceptible P. aeruginosa. This broad antimicrobial activity might allow ceftobiprole to be an alternative to dual therapy combinations when potential drug toxicities, drug-drug or drug disease interactions are concerns for other agents. PMID- 27690688 TI - Infections caused by Mycobacterium abscessus: epidemiology, diagnostic tools and treatment. AB - INTRODUCTION: Mycobacterium abscessus is an emerging mycobacteria that is responsible for lung diseases and healthcare-associated extrapulmonary infections. Recent findings support its taxonomic status as a single species comprising 3 subspecies designated abscessus, bolletii and massiliense. We performed a review of English-language publications investigating all three of these subspecies. Areas covered: Worldwide, human infections are often attributable to environmental contamination, although the isolation of M. abscessus in this reservoir is very rare. Basic research has demonstrated an association between virulence and cell wall components and cording, and genome analysis has identified gene transfer from other bacteria. The bacteriological diagnosis of M. abscessus is based on innovative tools combining molecular biology and mass spectrometry. Genotypic and phenotypic susceptibility testing are required to predict the success of macrolide (clarithromycin or azithromycin) based therapeutic regimens. Genotyping methods are helpful to assess relapse and cross-transmission and to search for a common source. Treatment is not standardised, and outcomes are often unsatisfactory. Expert commentary: M. abscessus is still an open field in terms of clinical and bacteriological research. Further knowledge of its ecology and transmission routes, as well as host-pathogen interactions, is required. Because the number of human cases is increasing, it is also necessary to identify more active treatments and perform clinical trials to assess standard effective regimens. PMID- 27690690 TI - Dissociation of Molecular and Endocrine Circadian Rhythms in Male Mice Lacking Bmal1 in the Adrenal Cortex. AB - The circadian rhythm of glucocorticoids affects diverse physiological systems, including stress responses and the coordination of rhythmic functions in peripheral and central tissues. Circadian clocks are considered to be important coordinators of glucocorticoid release and loss of the core clock component Brain and muscle Arnt-like protein-1 leads to ablation of behavioral and physiological rhythms, hypocortisolism, impaired ACTH, and behavioral stress responses. Transplantation and conditional clock gene knock-down studies in mice suggest an important role of local adrenocortical clock function in this context. Here, we present a Cre-loxP-mediated conditional knockout of Bmal1 in the steroidogenic cells of the adrenal cortex in mice. Mutant animals show a loss of molecular clock gene activity rhythms in this tissue with subsequent disruption of rhythmic steroidogenic gene expression. However, despite this loss of normal clock rhythmicity in the adrenal cortex, behavioral and physiological rhythms and acute stress responses persist in mutant mice. These findings reveal a dissociation of transcriptional and endocrine rhythm regulation in the adrenal cortex, arguing for a less pivotal function of the local clock machinery in the regulation of circadian and acute glucocorticoid outputs. PMID- 27690691 TI - Induction of Amnion Epithelial Apoptosis by Cortisol via tPA/Plasmin System. AB - Rupture of fetal membranes (ROM) can initiate parturition at both term and preterm birth. Apoptosis of the amnion epithelium plays a key role in structural remodeling of the membranes preceding ROM. However, the causative factors for apoptosis remain unidentified. Toward the end of gestation, a feed-forward regeneration of cortisol via 11beta-hydroxysteroid dehydrogenase 1 exists in the fetal membranes. Here, we have examined whether cortisol accumulation is a causative factor for amnion cells apoptosis. By using primary human amnion epithelial and fibroblast cells, we demonstrated cortisol induced apoptosis specifically in epithelial cells but not in fibroblasts via reciprocal regulation of tissue-type plasminogen activator (tPA)/plasmin system. Cortisol increased PLAT expression, the gene encoding tPA, via glucocorticoid receptor binding to a glucocorticoid response element in PLAT promoter, thereby increasing plasmin activity in epithelial cells. Further study revealed that a Fas-mediated extrinsic apoptotic pathway was involved in the induction of epithelial cells apoptosis by cortisol, which was blocked by inhibiting either tPA or plasmin. Consistently, cortisol increased cleaved-caspase-3 and tPA abundance in amnion tissue explants. Moreover, the abundance of cortisol, cleaved-caspase-3, and tPA was significantly increased in amnion tissue after labor-initiated spontaneous rupture of membranes. In conclusion, local accumulation of cortisol is a causative factor for amnion epithelial apoptosis via activation of tPA/plasmin system toward the end of gestation. This may contribute to the ROM at both term and preterm birth. PMID- 27690692 TI - FGF21-FGFR1 Coordinates Phospholipid Homeostasis, Lipid Droplet Function, and ER Stress in Obesity. AB - The antiobese and antidiabetic fibroblast growth factor 21 (FGF21) regulates lipid metabolism and energy homeostasis by targeting the betaKlotho-FGFR1 (fibroblast growth factor receptor 1) binary complex in adipose tissue adipocytes. Because lipid droplet is the organelle responsible for storing lipid energy in adipocytes, it is the plausible target of FGF21 action. However, the impact of the FGF21-betaKlotho-FGFR1 signaling pathway on the functions of the lipid droplet is not clearly understood. Using our mouse models of adipocyte specific FGFR1 ablation and hepatic overexpression of FGF21 with diet-induced obesity established previously, we analyzed the alterations of the pathways involved in energy and substrate metabolism that is attributable to the dynamic functions of the lipid droplet. In addition to the previous reports showing that FGFR1 deficiency abrogated lipolysis, fatty acid oxidation, and energy expenditure promoted by the elevated FGF21 signal, we observed that the deficiency up-regulated the biosynthesis and remodeling of membrane phospholipids that are important for the biogenesis and expansion of the droplet, whereas the enhanced FGF21 signal constrained the biosynthesis of phospholipids. As a result, the loss of adipose FGFR1 led to a sustained droplet expansion and endoplasmic reticulum (ER) stress, whereas the enhanced FGF21 signal suppressed them in obesogenesis. These new findings reveal that the FGF21-betaKlotho-FGFR1 signaling axis plays roles in maintaining phospholipid homeostasis and the dynamic functions of the lipid droplet, whereas protecting against ER stress, and suggest a potential link of phospholipid biosynthesis, lipid droplet dynamics, ER stress, and energy homeostasis in adipose tissue coordinated by this signaling axis. PMID- 27690693 TI - Applicability of the Proposed Japanese Model for the Classification of Gastric Cancer Location: The "PROTRADIST" Retrospective Study. AB - BACKGROUND: The extension of lymphadenectomy for surgical treatment of gastric cancer remains discordant among European and Japanese surgeons. Kinami et al. (Kinami S, Fujimura T, Ojima E, et al. PTD classification: proposal for a new classification of gastric cancer location based on physiological lymphatic flow. Int. J. Clin. Oncol. 2008;13:320-329) proposed a new experimental classification, the "Proximal zone, Transitional zone, Distal zone" (PTD) classification, based on the physiological lymphatic flow of gastric cancer site. The aim of the present retrospective study is to assess the applicability of PTD Japanese model in gastric cancer patients of our Western surgical department. METHODS: Two groups of patients with histologically documented adenocarcinoma of the stomach were retrospectively obtained: In the first group were categorized 89 patients with T1a-T1b tumor invasion; and in the second group were 157 patients with T2-T3 category. The data collected were then categorized according to the PTD classification. RESULTS: In the T1a-T1b group there were no lymph node metastases within the r-GA or r-GEA compartments for tumors located in the P portion, and similarly there were no lymphatic metastases within the l-GEA or p-GA compartments for tumors located in the D portion. On the contrary, in the T2-T3 group the lymph node metastases presented a diffused spreading with no statistical significance between the two classification models. CONCLUSIONS: Our results show that the PTD classification based on physiological lymphatic flow of the gastric cancer site is a more physiological and clinical version than the Upper, Medium And Lower classification. It represents a valuable and applicable model of cancer location that could be a guide to a tailored surgical approach in Italian patients with neoplasm confined to submucosa. Nevertheless, in order to confirm our findings, larger and prospective studies are needed. PMID- 27690694 TI - Complications of invasive mycoses in organ transplant recipients. AB - INTRODUCTION: Opportunistic mycoses remain a significant complication in organ recipients. Areas covered: This review is an evidence-based presentation of current state-of-knowledge and our perspective on recent developments in the field Expert commentary: Invasive fungal infections are associated with reduced allograft and patient survival, increase in healthcare resource utilization, and newly appreciated but largely unrecognized immunologic sequelae, such as immune reconstitution syndrome. Given adverse outcomes associated with established infections, prophylaxis is a widely used strategy for the prevention of these infections. Currently available biomarkers that detect circulating fungal cell wall constituents i.e., galactomannan and 1, 3-beta-D-glucan have not proven to be beneficial as screening tools for employing targeted prophylaxis or as diagnostic assays in this patient population. However, subsets of patients at risk for opportunistic fungal infections can be identified based on clinically identifiable characteristics or events. Preventive strategies targeted towards these patients are a rational approach for optimizing outcomes. PMID- 27690695 TI - Placental leptin mRNA expression and serum leptin levels in pre-eclampsia associated with HIV infection. AB - Leptin, primarily produced by adipocytes, is implicated in the development of pre eclampsia. This study examines placental leptin production and serum leptin levels in HIV infected and uninfected normotensive and pre-eclamptic pregnancies. Placental leptin production was analysed by RT-PCR and serum leptin levels by ELISA in normotensive (n = 90) and pre-eclamptic (n = 90) pregnancies which were further stratified by HIV status. Placental leptin production was higher in pre eclampsia compared to normotensive pregnancies irrespective of HIV status (p = .04). Serum leptin was non-significantly raised in HIV uninfected (p = .42) but lower in HIV-infected (p = .03) pre-eclampsia. The latter had lower BMI (p = .007) and triceps skin-fold thickness (p < .001) than the HIV uninfected groups with a significant correlation between serum leptin and triceps skin-fold thickness (p < .001), indicative of less adipose tissue in HIV-infected women with consequently lower serum leptin. Thus, serum leptin levels are not indicative of increased placental production when pre-eclampsia is associated with HIV infection. PMID- 27690696 TI - Modified Adenovirus Reduces De Novo Peritoneal Adhesions in Rats and Limits Off Target Transfection. Role of EZH2 in Adhesion Formation. AB - AIM OF THE STUDY: Adenovector encoding tissue plasminogen activator (tPA) was shown to reduce experimental peritoneal adhesion. We investigated the targeting potential of our modified adenovector, its ability to reduce adhesions and the epigenetic role of histone methyltransferase EZH2 in adhesion formation. MATERIALS AND METHODS: Control lacZ, nonmodified tPA or modified tPA vectors were instilled in the peritoneal cavity after injury in de novo adhesions or after lysis of adhesions in recurrent adhesions. Adhesion severity was scored and adhesions and liver tissues were examined for adenovirus E4 gene and tPA mRNA expression. Levels of tPA, plasminogen activator inhibitor-1 (PAI-1), transforming growth factor-beta1 (TGF-beta1), and EZH2 expression were measured. RESULTS: E4 transcripts were detected in adhesions of nonmodified and modified and in livers of nonmodified but not in livers of modified de novo adhesions. Both nonmodified (p = 0.021) and modified vectors (p = 0.036) reduced the severity of de novo adhesions compared to lacZ vector. Levels of tPA in nonmodified (p = 0.021) and modified adhesions (p = 0.001) were elevated while PAI-1 (p = 0.013 and p = 0.001, respectively) and TGF-beta1 levels (p = 0.002 and p = 0.016, respectively) were reduced compared with lacZ group. All vectors were not expressed in recurrent adhesions and severity score were not different among groups. EZH2 levels were elevated in de novo nontreated (p = 0.001) and was further increased in recurrent (p = 0.001) nontreated adhesions compared with noninjured peritoneum. CONCLUSION: Modified adenovirus successfully targeted de novo adhesions but not liver tissues and reduced the severity of de novo adhesions. EZH2 is involved in the development and progression of peritoneal adhesions. PMID- 27690698 TI - Allopurinol Protective Effect of Renal Ischemia by Downregulating TNF-alpha, IL 1beta, and IL-6 Response. AB - Allopurinol is a well-known antioxidant that protects tissue against ischemia and reperfusion injury, blocking purine catabolism, and possibly reducing TNF-alpha and other cytokines. It also plays a significant role in reducing the inflammatory processes by inhibiting chemotaxis and other inflammatory mediators. The objective of this study was to define the role of allopurinol regarding kidney ischemic injury particularly as to its effect on inflammatory molecules such as TNF-alpha, IL-1beta, and IL-6 response. One hundred and twenty five rats were subjected to warm renal ischemia. Five more animals were included as sham. Animal survival and plasma levels of lipid peroxidation, myeloperoxidase, lactate dehydrogenase, glutathione, urea, creatinine, and cytokines were determined. Inflammatory parameters (TNF-alpha, IL-1beta, and IL-6) were measured in all groups by quantitative immunosorbent assay. Further, immunohistological and histopathological studies were carried out on animals treated prior to, or following reperfusion with 10 and 50 mg/kg of Allopurinol. The statistical analysis included ANOVA and Fisher test as well as chi2 test. Significance was reached at a p < 0.05. The results of this study indicated that Allopurinol protected against kidney ischemia-reperfusion injury since significantly better results of survival, biochemical analysis, and histopathological testing were observed in treated animals as compared to ischemic controls. In conclusion, Allopurinol protected ischemic kidneys through a mechanism associated with downregulation of TNF-alpha, IL-1 beta, and IL-6, in addition to other well-known effects such as decreased lipid peroxidation and neutrophil activity. It also increased antioxidant capacity and diminished endogenous peroxidase stain in renal ischemic tissue. Therefore, this experiment showed an effectiveness of allopurinol protection against proteomic and morphological damage. PMID- 27690697 TI - Antioxidant Effect of Ukrain Versus N-Acetylcysteine Against Acute Biliary Pancreatitis in An Experimental Rat Model. AB - : Purpose/Aim: Oxidative stress plays an important role in the pathogenesis of acute pancreatitis (AP). We compared the therapeutic effects of Ukrain (NSC 631570) and N-acetylcysteine (NAC) in rats with AP. MATERIALS AND METHODS: Forty male Sprague Dawley rats were divided into four groups: controls; AP; AP with NAC; and AP with Ukrain. AP was induced via the ligation of the bile-pancreatic duct; drugs were administered intraperitoneally (i.p.) 30 min and 12 h after AP induction. Twenty-four hours after AP induction, animals were sacrificed and the pancreas was excised. Levels of malondialdehyde (MDA) and nitric oxide (NO), and activity levels of tumor necrosis factor (TNF)-alpha, and myeloperoxidase (MPO) were measured in tissue samples. Total oxidant status (TOS), total antioxidant status (TAS), and total bilirubin, as well as activity levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), amylase and lipase were measured in serum samples. Pancreatic tissue histopathology was also evaluated. RESULTS: Test drugs reduced levels of MDA, NO, TNF-alpha, total bilirubin, AST, ALT, TOS and MPO, amylase and lipase activities (P < 0.001), and increased TAS (P < 0.001). Rats treated with test drugs attenuated AP-induced morphologic changes and decreased pancreatic damage scores compared with the AP group (P < 0.05). Both test drugs attenuated pancreatic damage, but the therapeutic effect was more pronounced in rats that received Ukrain than in those receiving NAC. CONCLUSIONS: These results suggest that treatment with Ukrain or NAC can reduce pancreatic damage via anti-inflammatory and antioxidant effects. PMID- 27690699 TI - Serum lipid profile and fatty acid composition of erythrocyte phospholipids in children and adolescents with primary hyperlipidemia. AB - This study aimed at characterizing the fatty acid (FA) composition of red blood cell (RBC) phospholipids in children and adolescents with primary hyperlipidemia, and to ascertain potential association with serum lipid profile and dietary factors. At this purpose, 54 probands aged 6-17 years were recruited. Subjects showed a low omega-3 index (eicosapentaenoic acid, EPA + docosahexaenoic acid, DHA <4%). Compared to males, females had a trend toward lower levels of total monounsaturated fatty acids (MUFA) and MUFA/saturated fatty acids (SFAs) ratio in RBCs. An inverse relationship between MUFA concentration in RBCs and serum cholesterol or HDL-C/triglycerides ratio was found. Omega-6 polyunsaturated fatty acids (n-6 PUFA) were positively associated to serum HDL-C levels, and inversely to dietary cholesterol. Fiber intake was positively associated with MUFA/SFA ratio. In conclusion, we provide the first experimental data on phospholipid FA composition of RBCs in hyperlipidemic children, showing sex differences and an overall low omega 3-index. PMID- 27690700 TI - The Role of Minimally Invasive Surgery in the Treatment of Lung Metastases. AB - INTRODUCTION: The ideal surgical approach for pulmonary metastasectomy remains controversial. Thoracoscopic surgery may offer advantages in quality of life outcomes, with equivalent oncologic long-term results. This study aimed to demonstrate the validity of video-assisted thoracoscopic surgery (VATS) in the treatment of lung metastases. METHODS: In all 224 patients who underwent 300 VATS metastasectomies from January 2000 to December 2013 were retrospectively reviewed. Sixty-nine patients underwent major resection (68 thoracoscopic lobectomies and one pneumonectomy) and 155 patients underwent a wedge resection/segmentectomy. Complete curative pulmonary resections were performed in 219 (97%) cases. The Kaplan-Meier method was used to estimate survival curves. Univariate and subsequent multivariate Cox model regression were performed to identify independent factors of overall survival. RESULTS: One hundred eighty-six patients developed lung metastases from epithelial tumors, 28 from sarcomas, seven from melanomas, and three from germ cell tumors. The final pathological examination revealed no cases of R1 disease. After a mean follow-up of 40 months, 118 patients (53%) had died. According to a multivariate analysis, a better prognosis was not observed for patients with a particular histological type; in addition, disease-free interval time, age, number of metastases, and type of surgery did not have any statistical influence on long-term survival. CONCLUSIONS: Thoracoscopic surgery is a safe and efficacious procedure, with a five-year overall survival that is equivalent to open surgery.

AB - INTRODUCTION: Calcium phosphate was used as an adjuvant in France in diphtheria, tetanus, pertussis and poliomyelitis vaccines. It was later completely substituted by alum salts in the late 80's, but it still remains as an approved adjuvant for the World Health Organization for human vaccination. Area covered: Thus, calcium phosphate is now considered as one of the substances that could replace alum salts in vaccines. The aim of this paper is to draw a review of existing data on calcium phosphate as an adjuvant in order to bring out the strengths and weaknesses for its use on a large scale. Expert commentary: Calcium phosphate is a compound naturally present in the organism, safe and already used in human vaccination. Beyond comparisons with the other adjuvants, calcium phosphate represents a good candidate to replace or to complete alum salts as a vaccine adjuvant.

AB - INTRODUCTION: Community acquired pneumonia (CAP) is a major health problem in elderly persons and is associated with high morbidity and mortality. Areas covered: This article reviews the most recent publications relative to CAP in the elderly population, with a focus on epidemiology, prognostic factors, microbial etiology, therapy and prevention. The data discussed in this review were mainly obtained from a non-systematic review using Medline, and references from relevant articles. Expert Commentary: CAP can occur at any age, but its incidence and risk of death are linked to increasing age. Age-related changes in the immune system make this population more vulnerable to CAP. Mortality in hospitalized patients with CAP ranges from 10% to 12%. However, in the case of elderly patients, several studies have reported mortality rates of up to 25%. Pneumococcal and influenza vaccination comprise one of the most important preventive approaches for CAP in the elderly. PMID- 27690703 TI - A Novel Method for Evaluating Postoperative Adhesions in Rats. AB - : Purpose/Aim: Postoperative adhesions remain an undesirable and commonly symptomatic side effect of abdominopelvic surgeries. Animal models of postoperative adhesions typically yield heterogeneous adhesions throughout the abdominal cavity and are not easily quantified. Here we present a novel method of postoperative adhesion assessment and report its reliability and measurement error. MATERIALS AND METHODS: A model of cecal abrasion with partial sidewall attachment was performed on female rats. After 1, 2, 4, or 7 days of recovery, the rats were euthanized and their abdominopelvic cavities were systematically evaluated for postoperative adhesions. The necropsy was recorded through the surgical microscope. Four raters were trained to use a ballot to capture key factors of the adhesions as they viewed the recordings. Their ratings were compared for measurement error and reliability (using Bland-Altman plots and intraclass correlation coefficients, respectively) and for the ability to discriminate differences in experimental groups. A subset of the data was analyzed to determine practical utility. RESULTS: The rating system was shown to have low measurement error and high inter-rater reliability for all parameters measured. Applied practically, the system was able to discriminate groups in a manner that was expected. CONCLUSIONS: We have developed and validated a rating system for postoperative adhesions and shown that it can detect group differences. This method can be used to quantify postoperative adhesions in rodent models.

AB - INTRODUCTION: Standard measles control strategies include achieving high levels of measles vaccine coverage using routine delivery systems, supplemented by mass immunization campaigns as needed to close population immunity gaps. Areas covered: This review looks at how supplementary immunization activities (SIAs) have contributed to measles control globally, and asks whether such a strategy has a place in Pacific Islands today. Expert commentary: Very high coverage with two doses of measles vaccine seems to be the optimal strategy for controlling measles. By 2015, all but two Pacific Islands had introduced a second dose in the routine schedule; however, a number of countries have not yet reached high coverage with their second dose. The literature and the country reviews reported here suggest that a high coverage SIA combined with one dose of measles vaccine given in the routine system will also do the job. The arguments for and against the use of SIAs are complex, but it is clear that to be effective, SIAs need to be well designed to meet specific needs, must be carried out effectively and safely with very high coverage, and should, when possible, carry with them other public health interventions to make them even more cost-effective. PMID- 27690705 TI - Refinement of Tissue-Engineering Chamber Implantation in the Rat. AB - PURPOSE: Rodent in vivo models that successfully generate new adipose, muscle, or vascular tissue in a tissue-engineering chamber (TEC) has advanced in the last decade. In this article, technical refinements in these operative foreign body implantations have been described to improve the execution of animal models in a way so that they can reduce wastage of time and resources. MATERIALS & METHODS: Male Sprague-Dawley rats were studied and randomly divided into two equal sized groups. In each group, a different operative procedure was used for implanting the TEC. Twenty animals were operated with diagonal incisions in the groin region, followed by staples for wound closure after TEC implantation. The remaining 20 animals received longitudinal incisions in the abdominal region followed by wound closure with ongoing intradermal nonresorbable sutures and skin glue. The outcome of both procedures with regard to complications, animal growth, and experimental failure was compared. Statistical analysis was performed using the nonparametric chi-squared (chi2) test. RESULTS: Significant difference in wound dehiscence was recorded in Group I as compared to Group II (p = 0.0001). Consequently, 55% of the experiments had to be aborted in Group I and the animals were removed from the experiment. On the contrary, in Group II, all the animals could be kept. CONCLUSION: Median longitudinal incisions and thorough wound closure with ongoing intradermal nonresorbable sutures, followed by application of skin glue, are strongly recommended to prevent surgical site complications, such as wound dehiscence, animal harm, and failure of the individual experiment. PMID- 27690707 TI - Muscle strength and quality of life in patients with childhood cancer at early phase of primary treatment. AB - Cancer- and treatment-related side effects in patients with childhood cancer may cause limitations in motor performance affecting activities of daily living (ADLs). Data focusing on long-term effects are available, but little is known with regard to the short-term perspective. Therefore, the purpose of this study was to assess muscle strength performance and quality of life (QoL) in children and adolescents with cancer at the beginning of primary treatment. Forty children and adolescents aged 5-18 years (mean: 11.39 +/- 4.08 years) with different types of childhood cancer were enrolled. On average 36 +/- 20.5 days after diagnosis, strength performance in 7 muscle groups was assessed by handheld dynamometry. KINDL questionnaires were completed to evaluate QoL (children's self-report and parents' report). All parameters were compared with age- and gender-matched reference values. Patients with childhood cancer showed significantly lower strength values in all muscle groups (P < .01) compared with age- and gender matched controls. Most affected were the lower extremities, with a -57.1% +/- 10.4%, median: -59.2%, minimum: -75.4%, maximum: -41.4% percentage deviation in knee flexion from healthy peers. Children themselves and parents assessed total QoL significantly below age- and gender-matched reference values (P < .01). Correlation between elbow flexion and self-reported QoL was detected. Broader correlations were found for the parents' report. Muscle weakness and decreased QoL in children and adolescents seem to persist already at the beginning of anticancer treatment. This underlines the need of counteracting measures, such as exercise intervention programs, starting as early as possible during the treatment process. Efforts on this topic are currently being carried out by our group. PMID- 27690706 TI - Families and medication use and adherence among Latinos with schizophrenia. AB - BACKGROUND: Medication nonadherence among Latinos with schizophrenia represents a significant treatment obstacle. Although some studies have examined patient and family perceptions of adherence, few have examined these perceptions together. However, such knowledge can provide a deeper understanding of how family processes may contribute to or impede adherence among underserved groups such as Latinos. AIMS: This study explored perceptions of medication and adherence among Latinos with schizophrenia and key family members. METHOD: Purposive sampling was used to collect data from 34 participants: 14 patients with schizophrenia receiving community-based mental health services in an urban public setting and 20 key family members. Informed by grounded theory, semistructured interviews were analyzed by bilingual-bicultural team members. RESULTS: Salient themes emerged indicating facilitators of and obstacles to medication use. Specifically, challenges centered on medication side effects, autonomy and choice, and illness insight, whereas facilitators focused on family support and holistic views of treatment and empowerment. CONCLUSIONS: Because the majority of Spanish-speaking Latinos with schizophrenia live with family, it is important to examine family factors that may influence medication use. Findings suggest that patient and family perceptions of medication should be examined as part of the treatment process, particularly regarding issues of autonomy and choice. PMID- 27690708 TI - Characterization of mothers at risk of delivery at the limit of viability and factors related to infant survival. AB - OBJECTIVES: To determine the sociodemographic and clinical characteristics of mothers of infants at the limit of viability and to know the perinatal factors associated to infants' survival. METHOD: Single-center cohort study of mothers and newborns assisted in our tertiary care center (2004-2010). Demographic and perinatal variables were compared between mothers who gave birth <=26 weeks GA and the general population. The association between perinatal factors and neonatal survival was studied by Cox regression analysis. RESULTS: Mothers of newborns <=26 weeks (n = 136) had less education and pregnancy control. They had more frequently assisted reproductive technologies (ART) (5.2% versus 2.3%; p< 0.05), multiple gestations (16.6% versus 2.1%; p < 0.05), pregnancy complications and C-section (39.7% versus 13.4%; p < 0.001). After correcting for confounders, the perinatal factors independently associated with a variation in the risk of mortality were the administration of antenatal steroid [aHR (95%CI): 0.465 (0.254 0.853), p = 0.013], singleton pregnancy [aHR (95%CI): 0.482 (0.279-0.834), p = 0.009], infant's temperature on admission [aHR (95%CI): 0.642 (0.426-0.968), p = 0.035] and CRIB score [aHR (95%CI): 1.151 (1.058-1.251), p = 0.001]. CONCLUSIONS: Mothers of preterm infants at the limit of viability had more ART, multiple pregnancies, obstetrical complications and C-section. Infants' survival was independently associated to antenatal steroids, singleton pregnancy, temperature on admission and CRIB score. PMID- 27690709 TI - Glomerular Glucocorticoid Receptors Expression and Clinicopathological Types of Childhood Nephrotic Syndrome. AB - Glucocorticoids are primary therapy of idiopathic nephrotic syndrome (INS). However, not all children respond to steroid therapy. We assessed glomerular glucocorticoid receptor expression in fifty-one children with INS and its relation to response to steroid therapy and to histopathological type. Clinical, laboratory and glomerular expression of glucocorticoid receptors were compared between groups with different steroid response. Glomerular glucocorticoid expression was slightly higher in controls than in minimal change early responders, which in turn was significantly higher than in minimal change late responders. There was significantly lower glomerular glucocorticoid receptor expression in steroid-resistance compared to early responders, late responders and controls. Glomerular glucocorticoid expression was significantly higher in all minimal change disease (MCD) compared to focal segmental glomerulosclerosis. In INS, response to glucocorticoid is dependent on glomerular expression of receptors and peripheral expression. Evaluation of glomerular glucocorticoid receptor expression at time of diagnosis of NS can predict response to steroid therapy. PMID- 27690711 TI - The factor structure of the mental health continuum-short form (MHC-SF) in Serbia: an evaluation using exploratory structural equation modeling. AB - BACKGROUND: The Mental Health Continuum-Short Form (MHC-SF) is a brief measure to assess emotional, social, and psychological well-being. AIMS: We examined the factor structure of the MHC-SF in Serbia. A secondary goal was to examine measurement invariance and latent mean differences across gender. METHOD: The methods of Confirmatory Factor Analysis (CFA) and Exploratory Structural Equation Modeling (ESEM) were used to investigate the factor structure of the scale in a large sample (N = 1883). We compared 1-, 2-, and 3-factor models of mental well being. RESULTS: The results supported the superiority of the 3-factor model of well-being over the alternatives. ESEM yielded better fit with the data and considerably smaller factor correlations than did CFA. ESEM also uncovered a number of cross-loadings in the MHC-SF. Full measurement invariance was established across gender, yet no significant gender differences were identified in the latent means. CONCLUSIONS: These results indicate that emotional, social, and psychological well-being represents correlated yet distinct factors in Serbia. The results also suggest that ESEM is a more appropriate method than CFA for examining the factor structure of mental well-being. The contributions of ESEM to current debates surrounding the distinction between hedonic and eudaimonic well-being are discussed. PMID- 27690710 TI - Achieve control: a pragmatic clinical trial of insulin glargine 300 U/mL versus other basal insulins in insulin-naive patients with type 2 diabetes. AB - OBJECTIVE: This study aims to compare the effectiveness of insulin glargine 300 U/mL (Gla-300) with its accompanying patient support program with that of other basal insulin and available patient support programs in patients with type 2 diabetes (T2D) in a real-world setting in terms of achieving HEDIS (Healthcare Effectiveness Data and Information Set) individualized glycemic targets without documented symptomatic hypoglycemia. METHODS: Achieve Control is a US-based, multicenter, randomized, open-label, active-controlled, parallel group pragmatic Phase IV trial in insulin-naive patients with T2D uncontrolled on >=2 oral antidiabetes drugs (OAD) and/or glucagon-like peptide-1 receptor antagonists (GLP 1 RA). Inclusion criteria include a diagnosis of T2D, age >=18 years, and glycated hemoglobin (HbA1c) between 8.0% and 11.0%. Patients will be assigned to either the Gla-300 or other basal insulin group. The primary end point is the proportion of patients achieving HEDIS HbA1c targets (<8.0% [64 mmol/mol] in patients with comorbidities or aged >=65 years; <7.0% [58 mmol/mol] in all other patients) without occurrence of symptomatic hypoglycemia (blood glucose <=70 mg/dL) from baseline to 6 months. Secondary end points include rates of documented symptomatic nocturnal hypoglycemia and severe hypoglycemia; change from baseline in HbA1c, fasting glucose, and body weight; treatment persistence; patient-reported outcomes; and healthcare resource utilization. Planned enrollment is 3270 patients across approximately 400 clinical sites. CONCLUSION: Pragmatic clinical trials offer the potential to assess comparative effectiveness in broadly based patient populations receiving care (with or without a corresponding educational support program) in real-world clinical settings. The results of Achieve Control should elucidate the benefits of management of T2D with Gla-300 versus other basal insulins in terms of patient outcomes, experiences, and perceptions, and its impact on healthcare resource utilization and cost.

PMID- 27690712 TI - Australian mental health nurses' perspectives about the identification and management of antipsychotic medication side effects: a cross-sectional survey. AB - BACKGROUND: Currently, little is known about mental health nurses' management of antipsychotic medication side effects. AIMS: This study examined how Australian mental health nurses' attitudes and service processes influence the assessment of antipsychotic medication side effects. METHODS: Participants were included if they were registered nurses in Australian mental health settings. An online questionnaire was distributed via email. Multivariate logistic regression was used to examine associations between attitudes and awareness, and use of antipsychotic medication assessment tools. RESULTS: Only one quarter of the respondents were currently using a tool. In cases where the service had a clear system for agreeing responsibility about monitoring consumers between primary and secondary care, respondents were three times more likely to still be using one or more tool. When the service had reliable systems in place to remind staff that side effect assessments were due, respondents were five times more likely to continue using assessment tools. CONCLUSION: Australian mental nurses are not routinely using antipsychotic medication side effect assessment tools. The routine use of assessment tools would improve if systems were implemented to enhance their use. PMID- 27690713 TI - Targeting microsomal triglyceride transfer protein and lipoprotein assembly to treat homozygous familial hypercholesterolemia. AB - Homozygous familial hypercholesterolemia (HoFH) is a polygenic disease arising from defects in the clearance of plasma low-density lipoprotein (LDL), which results in extremely elevated plasma LDL cholesterol (LDL-C) and increased risk of atherosclerosis, coronary heart disease, and premature death. Conventional lipid-lowering therapies, such as statins and ezetimibe, are ineffective at lowering plasma cholesterol to safe levels in these patients. Other therapeutic options, such as LDL apheresis and liver transplantation, are inconvenient, costly, and not readily available. Recently, lomitapide was approved by the Federal Drug Administration as an adjunct therapy for the treatment of HoFH. Lomitapide inhibits microsomal triglyceride transfer protein (MTP), reduces lipoprotein assembly and secretion, and lowers plasma cholesterol levels by over 50%. Here, we explain the steps involved in lipoprotein assembly, summarize the role of MTP in lipoprotein assembly, explore the clinical and molecular basis of HoFH, and review pre-clinical studies and clinical trials with lomitapide and other MTP inhibitors for the treatment of HoFH. In addition, ongoing research and new approaches underway for better treatment modalities are discussed. PMID- 27690714 TI - Can EMS Providers Provide Appropriate Tidal Volumes in a Simulated Adult-sized Patient with a Pediatric-sized Bag-Valve-Mask? AB - INTRODUCTION: In the prehospital setting, Emergency Medical Services (EMS) professionals rely on providing positive pressure ventilation with a bag-valve mask (BVM). Multiple emergency medicine and critical care studies have shown that lung-protective ventilation protocols reduce morbidity and mortality. Our primary objective was to determine if a group of EMS professionals could provide ventilations with a smaller BVM that would be sufficient to ventilate patients. Secondary objectives included 1) if the pediatric bag provided volumes similar to lung-protective ventilation in the hospital setting and 2) compare volumes provided to the patient depending on the type of airway (mask, King tube, and intubation). METHODS: Using a patient simulator of a head and thorax that was able to record respiratory rate, tidal volume, peak pressure, and minute volume via a laptop computer, participants were asked to ventilate the simulator during six 1-minute ventilation tests. The first scenario was BVM ventilation with an oropharyngeal airway in place ventilating with both an adult- and pediatric-sized BVM, the second scenario had a supraglottic airway and both bags, and the third scenario had an endotracheal tube and both bags. Participants were enrolled in convenience manner while they were on-duty and the research staff was able to travel to their stations. Prior to enrolling, participants were not given any additional training on ventilation skills. RESULTS: We enrolled 50 providers from a large, busy, urban fire-based EMS agency with 14.96 (SD = 9.92) mean years of experience. Only 1.5% of all breaths delivered with the pediatric BVM during the ventilation scenarios were below the recommended tidal volume. A greater percentage of breaths delivered in the recommended range occurred when the pediatric BVM was used (17.5% vs 5.1%, p < 0.001). Median volumes for each scenario were 570.5mL, 664.0mL, 663.0mL for the pediatric BMV and 796.0mL, 994.5mL, 981.5mL for the adult BVM. In all three categories of airway devices, the pediatric BVM provided lower median tidal volumes (p < 0.001). CONCLUSION: The study suggests that ventilating an adult patient is possible with a smaller, pediatric-sized BVM. The tidal volumes recorded with the pediatric BVM were more consistent with lung-protective ventilation volumes. PMID- 27690715 TI - Economic and clinical burden of opioid-induced nausea and vomiting. AB - Opioids are the standard of care for treating moderate-to-severe pain; however, their efficacy can be limited by adverse events (AEs), including nausea and vomiting. Opioid-induced nausea and vomiting (OINV) is an inherent adverse effect of opioid treatment, exerting effects centrally and peripherally. Opioid-related AEs can impact treatment adherence and discontinuation, which can result in inadequate pain management. OINV may persist long-term, negatively affecting patient functional outcomes, physical and mental health, patient satisfaction, and overall costs of treatment. Multiple factors may contribute to OINV, including activation of opioid receptors in the chemoreceptor trigger zone, vestibular apparatus, and gastrointestinal tract. Prophylactic or early treatment with antiemetics may be appropriate for patients who are at high risk for OINV. PMID- 27690716 TI - Development of a combined radiation and full thickness burn injury minipig model to study the effects of uncultured adipose-derived regenerative cell therapy in wound healing. AB - PURPOSE: To develop an approach that models the cutaneous healing that occurs in a patient with full thickness thermal burn injury complicated by total body radiation exposure sufficient to induce sub-lethal prodromal symptoms. An assessment of the effects of an autologous cell therapy on wound healing on thermal burn injury with concomitant radiation exposure was used to validate the utility of the model. METHODS: Gottingen minipigs were subjected to a 1.2 Gy total body irradiation by exposure to a 6 MV X-ray linear accelerator followed by ~10 cm2 full thickness burns (pre-heated brass block with calibrated spring). Three days after injury, wounds were excised to the underlying fascia and each animal was randomized to receive treatment with autologous adipose-derived regenerative cells (ADRC) delivered by local or intravenous injection, or vehicle control. Blood counts were used to assess radiation-induced marrow suppression. All animals were followed using digital imaging to assess wound healing. Full thickness biopsies were obtained at 7, 14, 21 and 30 days' post-treatment. RESULTS: Compared to animals receiving burn injury alone, significant transient neutropenia and thrombocytopenia were observed in irradiated subjects with average neutrophil nadir of 0.79 * 103/MUl (day 15) and platelet nadir of 60 * 103/MUl (day 12). Wound closure through a combination of contraction and epithelialization from the wound edges occurred over a period of approximately 28 days' post excision and treatment. Re-epithelialization was accelerated in wounds treated with ADRC (mean 3.5-fold increase at 2 weeks post-treatment relative to control). This acceleration was accompanied by an average 67% increase in blood vessel density and 30% increase in matrix (collagen) deposition. Similar results were observed when ADRC were injected either directly into the wound or by intravenous administration. CONCLUSIONS: Although preliminary, this study provides a reproducible minipig model of thermal burn injury complicated by myelosuppressive total body irradiation that utilizes standardized procedures to evaluate novel countermeasures for potential use following attack by an improvised nuclear device. PMID- 27690717 TI - The glycosylation of the extracellular loop of beta2 subunits diversifies functional phenotypes of BK Channels. AB - Large-conductance Ca2+- and voltage-activated potassium (MaxiK or BK) channels are composed of a pore-forming alpha subunit (Slo) and 4 types of auxiliary beta subunits or just a pore-forming alpha subunit. Although multiple N-linked glycosylation sites in the extracellular loop of beta subunits have been identified, very little is known about how glycosylation influences the structure and function of BK channels. Using a combination of site-directed mutagenesis, western blot and patch-clamp recordings, we demonstrated that 3 sites in the extracellular loop of beta2 subunit are N-glycosylated (N-X-T/S at N88, N96 and N119). Glycosylation of these sites strongly and differentially regulate gating kinetics, outward rectification, toxin sensitivity and physical association between the alpha and beta2 subunits. We constructed a model and used molecular dynamics (MD) to simulate how the glycosylation facilitates the association of alpha/beta2 subunits and modulates the dimension of the extracellular cavum above the pore of the channel, ultimately to modify biophysical and pharmacological properties of BK channels. Our results suggest that N-glycosylation of beta2 subunits plays crucial roles in imparting functional heterogeneity of BK channels, and is potentially involved in the pathological phenotypes of carbohydrate metabolic diseases. PMID- 27690718 TI - Water or realistic compositions in proton radiotherapy? An analytical study. AB - PURPOSE: Pre-clinical tests and simulation studies for radiotherapy are generally carried out using water or simplified materials. Investigating the effects of defining compositionally realistic media in proton transport studies was the objective of this work. Accurate modeling of the Bragg curve is a fundamental requirement for such a study. METHODS AND MATERIALS: An equation previously validated by experiments provides an appropriate analytical method for proton dose calculation in depth of the target. Owing to the dependency on protons ranges and the probability of undergoing non-elastic nuclear interactions (NNI), this formula comprises three parameters with values specified for initial proton energy and for the target material. As a result, knowledge of the depth-dose distribution using this analytical model is limited to the materials for which the data has been provided in nuclear data tables. In this study, we used our general formulas for calculating the protons ranges and the probability of undergoing NNI in desired compounds and mixtures with an arbitrary number of constituent elements. Furthermore, the protons dose distribution in the depth of these targets was leading off with determining the parameters appeared in the employed model using our mathematically easy to handle relations. For a number of tissues which may be of interest in proton radiotherapy studies but are missing in reference data tables, the mentioned parameters were calculated. Moreover, the resultant values for the protons ranges and the probability of undergoing NNIs were compared with those in water. RESULTS: The results showed that the differences between the position of Bragg peaks in water and realistic media considered in this study were energy dependent, and ranged between a few millimeters. For proton beams of arbitrary chosen initial energies, the maximum dose delivered to the realistic media varied between about -0.02-4.42% in comparison with that to water. CONCLUSIONS: The effects observed (both in penetration and in the magnitude of the Bragg peaks) may be overshadowed by the different dose prescriptions depending on the quality of the treatment planning system, and dosimetry protocols used at the various therapy centers. PMID- 27690719 TI - Gold nanoparticles in combination with megavoltage radiation energy increased radiosensitization and apoptosis in colon cancer HT-29 cells. AB - PURPOSE: Gold nanoparticles (GNP) act as a radiosensitizer in radiation therapy. However, recent studies have shown contradictory evidence in terms of radiosensitization in the presence of GNP combined with X-ray megavoltage energy (MV) on different cell types. In this study, the effect of GNP on radiosensitization enhancement of HT-29 human colorectal cancer cells at MV X-ray energy was evaluated. MATERIALS AND METHODS: The cytotoxicity and radiosensitization of GNP were evaluated in HT-29 human colorectal cancer cells by MTS-assay and multiple MTS-assay, respectively. Cellular uptake was assayed using graphite furnace atomic absorption spectrometry (GFAAS). Apoptosis and cell cycle progression were determined by an Annexin V-FITC/propidium iodide (PI) kit and PI/RNase solution with flow cytometry, respectively. RESULTS: Results showed that the cell viability of the HT-29 cells was not influenced by exposure to different concentrations of GNP (10-100 MUM). GNP alone did not affect the cell cycle progression and apoptosis. In contrast, GNP, in combination with radiation (9 MV), induced more apoptosis. The interaction of GNP with MV energy resulted in a significant radiosensitization enhancement compared with irradiation alone. CONCLUSION: It was concluded that GNP may work as bio-inert material on HT-29 cancer cells and their enhancement of radiosensitization may be due to increase in the absorbed irradiation dose. PMID- 27690720 TI - Alpha-fetoprotein and Fanconi Anemia: Relevance to DNA Repair and Breast Cancer Susceptibility. AB - Elevations of serum alpha-fetoprotein (sAFP) have been reported in fetal and infant states of anemia. Fanconi anemia (FA) belongs to a family of genetic instability disorders which lack the capability to repair DNA breaks. The lesion occurs at a checkpoint regulatory step of the G2 to mitotic transition, allowing FA cells to override cell-cycle arrest. FA DNA repair pathways contain complementation groups known as FANC proteins. FANC proteins form multi-protein complexes with BRCA proteins and are involved in homologous DNA repair. An impaired cascade in these events imparts an increased breast cancer susceptibility to female FA patients. Elevations of sAFP have availed this fetal protein to serve as a biomarker for FA disease. However, the origin of the synthesis of sAFA has not been determined in FA patients. We hypothesize that hematopoietic multipotent progenitor stem cells in the bone marrow are the source of sAFP production in FA patients. PMID- 27690721 TI - Contemporary challenges and opportunities in the diagnosis and outbreak detection of multidrug-resistant infectious disease. AB - INTRODUCTION: The dissemination of multi-drug resistant bacteria (MDRB) has become a major public health concern worldwide because of the increase in infections caused by MDRB, the difficulty in treating them, and expenditures in patient care. Areas covered: We have reviewed challenges and contemporary opportunities for rapidly confronting infections caused by MDRB in the 21st century, including surveillance, detection, identification of resistance mechanisms, and action steps. Expert commentary: In this context, the first critical point for clinical microbiologists is to be able to rapidly detect an abnormal event, an outbreak and/or the spread of a MDRB with surveillance tools so that healthcare policies and therapies adapted to a new stochastic event that will certainly occur again in the future can be implemented. PMID- 27690722 TI - Differential neutrophil chemotactic response towards IL-8 and bacterial N-formyl peptides in term newborn infants. AB - BACKGROUND: A prerequisite for an effective innate immunity is the migrative ability of neutrophils to respond to inflammatory and infectious agents such as the intermediate interleukin (IL)-8 and the end-target formyl-methionyl-leucyl phenylalanine (fMLP) chemoattractants. The aim was to study the chemotactic capacity of neutrophils from newborn infants and adults in response to IL-8 and the bacterial peptide fMLP. METHODS: In the under-agarose cell migration assay, isolated leukocytes from healthy adults and from cord blood of healthy term newborn infants were studied with dose responses towards IL-8 and fMLP. The same number of leukocytes (1 * 105 cells), with the same distribution of neutrophils and monocytes, were analyzed in neonates and adults. Chemotaxis was distinguished from randomly migrating neutrophils, and the neutrophil pattern of migration, i.e. the migration distance and the number of migrating neutrophils per distance, was evaluated. RESULTS: In comparison to adults, fewer neutrophils from newborn infants migrated towards IL-8 and for a shorter distance (P < .01, respectively). The number of neutrophils migrating to different gradients of fMLP, the distance they migrated, and the correlation between the number and the distance were the same for neonates and adults. Random migration did not differ in any instance. CONCLUSION: Chemotaxis of neutrophils from newborn infants was as co-ordinated as neutrophils from adults in response to fMLP, whereas the response to IL-8 was reduced. The differential response of neutrophils from neonates to intermediate and end-target chemoattractants could indicate a reduced infectious response. PMID- 27690723 TI - The relationship between: occupational status, biological condition and androgen hormone level among Polish adult men: the Wroclaw Male Study. AB - Population health and its determinants are one of the major challenges to social and economic policy. The aim of this study was to investigate the relationship between occupational activity and biological condition in adult working Polish men. The participants of the study were 300 men (30-65 years), healthy inhabitants of the city of Wroclaw, Poland. Seventeen measures of biological condition were examined. The subjects were divided into three different occupational groups: professionals, soldiers and skilled workers. A comparison of biological age profiles of three occupational groups showed that in the majority of characteristics, professionals had the youngest biological age, whereas skilled workers had the highest biological age. The results for soldiers were not as unambiguous, but biological parameters were generally closer to those for professionals. Inborn biological predispositions and long-term impact of the working environment can influence on the biological condition of various professional groups.

AB - OBJECTIVES: To investigate correlation of the white blood cell (WBC) and its subtype count with the traditional and non-traditional components of the metabolic syndrome. METHODS: Between January 2012 and December 2013, 18,222 people were enrolled in this study. The height, weight, body mass index (BMI) and blood pressure were measured, and blood samples were tested for all subjects after an overnight fast. The count of WBC and its subtypes, total cholesterol, triglyceride, high density lipoprotein (HDL), low-density lipoprotein, aminotransferases, fibrinogen, uric acid, and fasting blood glucose were all assessed. RESULTS: Metabolic syndrome was found in 2502 of 18,222 healthy Chinese people (16.41%). The prevalence of metabolic syndrome was 22.61% for men significantly (P < 0.05) greater than for women (6.83%). The prevalence of obesity, hypertension, hyperglycemia and hyperlipidemia was significantly (P < 0.001) higher in people with than without metabolic syndrome. With increase of the WBC count, BMI, systolic and diastolic pressure, fasting blood glucose, triglyceride, glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, glutamyltranspetidase, blood urea nitrogen fibrinogen and uric acid all went up significantly (P < 0.001) while HDL decreased significantly (P < 0.05). The creatinine remained relatively sTable After adjustment of age, sex, alcoholic drinking and education, the metabolic components of obesity, hypertension, diabetes and hyperlipidemia rose significantly (P < 0.05) positively with increased counts of the total WBC, neutrophil and lymphocyte, and the WBC and its subtypes were an independent risk factor for metabolic syndrome. CONCLUSION: Aminotransferases, fibrinogen and uric acid all significantly increase with increased WBC count in a dose-dependent manner. Increased counts of the total WBC and its subtypes are positively associated with presence of metabolic syndrome. PMID- 27690725 TI - Histological chorioamnionitis in preterm prelabor rupture of the membranes is associated with increased expression of galectin-3 by amniotic epithelium. AB - PURPOSE: Gal-3, which can regulate immune responses upon infection and inflammation, was not studied so far in intrauterine infection leading to preterm prelabor rupture of the membranes (PPROM), although gal-1 was reported to be implicated in the process. Gal-3 mRNA and protein expression in amnion and its changes during histological chorioamnionitis were studied here. MATERIALS AND METHODS: Fetal membranes were obtained from women with PPROM with (n =15) and without histological chorioamnionitis (n =15) during second and third trimester. Immunohistochemical reactivity was evaluated semiquantitatively and analyzed using t-test. Galectin profile of amniotic epithelia was determined by polymerase chain reaction (PCR) and change assessed in gal-3 in PPROM with (n =5) or without histological chorioamnionitis (n =5) by real-time PCR. RESULTS: Human amniotic epithelium was found to express gal-1, gal-3, gal-7 and gal-8 mRNA. Gal-3 mRNA and protein is increased in fetal membranes and in the amniotic epithelium in patients with chorionamnionitis. CONCLUSION: Histological chorioamnionitis is associated with increased gal-3 expression and strong immunoreactivity of the amnion. Gal-3 may participate in the regulation of the inflammatory responses to chorioamniotic infection and/or direct interaction with pathogens. PMID- 27690726 TI - Can Human Recombinant Epidermal Growth Factor Improve Ischemia and Induce Healing of Anastomosis in an Experimental Study in a Rabbit Model? AB - PURPOSE: Anastomotic leaks following intestinal operations may cause devastating effects on patients. Ischemia may also occur at the intestinal walls in the presence of strangulations. In this study, we examined the effects of human recombinant (Hr)-epidermal growth factor (EGF) given at a single intramural dose into the intestinal walls and daily intraperitoneal cavity on ischemia and the healing process of anastomosis. MATERIALS AND METHODS: Sixteen male New Zeland white rabbits were randomly divided into four groups (n = 4 in each group). In Group 1, two different segments of ileum were identified and, then, transected and the free ends were sutured each other. In the other groups, ischemia was induced by ligating the mesenteric vascular arcade. After the ischemic induction, Group 2 received intramural injections of %0.9 saline, Group 3 received intramural injections of a single dose of EGF, and Group 4 received intramural and intraperitoneal injections of EGF. Bursting pressures and tissue hydroxyproline levels were analyzed. Necrosis, fibroblastic activity, collagen deposition and neovascularization were also studied. RESULTS: The mean levels of bursting pressures in Group 4 (148.6 +/- 25.3 mmHg) were higher than Group 2 (70 +/- 21.5 mmHg) (p = 0.001). The mean level of bursting pressures was not statistically significant between Group 1 (170.1 +/- 35 mmHg) and Group 4 (p = 0.073). Hydroxyproline levels in Group 2 were lower than Groups 3 and 4. There was a statistically significant difference in the mucosal ischemia, mucosal healing and degree of adhesion, but not in the mural anastomotic healing among the groups. CONCLUSIONS: Intramural injection with daily intraperitoneal administration of low-dose EGF enhances the bursting pressure and collagen accumulation in ischemic anastomosis, improving many histological variables associated with ischemic intestinal anastomosis. PMID- 27690727 TI - Cord blood erythropoietin and cord blood nucleated red blood cells for prediction of adverse neonatal outcome associated with maternal obesity in term pregnancy: prospective cohort study. AB - OBJECTIVE: To determine the adverse pregnancy outcomes associated with maternal pre-pregnancy overweight and obesity and we measure cord blood erythropoietin and NRBC count as indices of hypoxia and predictors of neonatal outcome. STUDY DESIGN: This prospective cohort study was done in Minia University Hospital, carried out from May 2015 to April 2016. Two hundred and seventy full-term neonates born to mothers of various body mass indices were included. Excluded were neonates with major factors known to be associated with a potential increase in fetal erythropoiesis. Pre-pregnancy maternal BMI was calculated from maternally reported weight and height. Cord blood erythropoietin and nucleated red blood cells were measured. RESULTS: There is a significant increase of various adverse pregnancy outcomes as cesarean section. Postpartum hemorrhage and macrosomia with the increase of maternal pre-pregnancy BMI. Significant positive correlations between cord blood erythropoietin and nucleated red blood cells with maternal BMI. CONCLUSION: The increase in the maternal pre-pregnancy BMI is associated with poor pregnancy outcomes. Cord blood erythropoietin and nucleated red blood cells can predict the poor neonatal outcome. PMID- 27690728 TI - Vacuum erection device in treatment of organic erectile dysfunction and penile vascular differences between patients with DM type I and DM type II. AB - The aim of this study is to investigate changes in the vascular system and hemodynamics between patients with organic erectile dysfunction (ED) (DM type I and II), as well as to compare the quality of sexual life between those two groups after the treatment with vacuum erection device (VED). Study enrolled 50 males with DM, aged from 35 to 67 years, who have attended the urologic clinic due to inability to attain and maintain an erection of the penis sufficient to permit satisfactory sexual intercourse. Patients were using VED and six months later were assessed for therapy results. The International Index of Erectile Function (IIEF) was used to quantify erectile dysfunction. Alprostadil injection test was also used, with Doppler color flow imaging system, to evaluate the peak systolic velocity (PSV) and diameter of cavernosal artery (DCA). Significantly higher values of PSV were obtained in patients with DM type II. Also, DCA showed significant difference between two groups of patients. There was significant improvement in three items of IIEF after six months of treatment among both groups of examinees. Patients with DM type I had more serious risk for development of arteriogenic ED. VED could be a good alternative therapy for patients who denied peroral therapy. PMID- 27690731 TI - Corrigendum. PMID- 27690729 TI - Endothelin-1 receptor drives invadopodia: Exploiting how beta-arrestin-1 guides the way. AB - Metastatization is a complex multistep process requiring fine-tuned regulated cytoskeleton re-modeling, mediated by the cross-talk of actin with interacting partners, such as the Rho GTPases. Our expanding knowledge of invadopodia, small invasive membrane protrusions composed of a core of F-actin, actin regulators and actin-binding proteins, and hotspots for secretion of extracellular matrix (ECM) proteinases, contributes to clarify critical steps of the metastatic program. Growth factor receptors and their intermediate signaling molecules, along with matrix adhesion and rigidity, pH and hypoxia, act as drivers of cytoskeleton changes and invadopodia formation. We recently pro-posed a novel route map by which cancer cells regulates invadopodia dynamics supporting metastasis as response to the endothelin A receptor (ETAR), among the highly druggable G protein coupled receptors in cancer. The metastatic behavior exhibited by ovarian cancer cells overe-xpressing ETAR is now explained by the interplay with beta arrestin1 (beta-arr1), a scaffold protein acting as signal-integrating module of RhoC and cofilin signaling for specific invadopodia formation, accomplished by its interaction with a Rho guanine nucleotide exchange factor (GEF), PDZ-RhoGEF, in a G-protein independent manner. Here, we summarize this novel activation of the RhoC pathway from ETAR/beta-arr1 signaling that may be exploited therapeutically and discuss new perspectives for future directions of investigations. PMID- 27690730 TI - Chk1 and DNA-PK mediate TPEN-induced DNA damage in a ROS dependent manner in human colon cancer cells. AB - Recently, we showed that the metal chelator TPEN targets colon cancer cells through redox cycling of copper. Here, we studied the DNA damage potential of TPEN and deciphered the role of Chk1, ATM and DNA-PK in TPEN-induced toxicity in 3 human colon cancer cell lines, HCT116, SW480 and HT29. We also investigated the role of reactive oxygen species (ROS) in TPEN-induced DNA damage. TPEN reduced cell viability in a dose- and time-dependent manner. Cytotoxicity was associated with significant DNA damage and higher expression of gamma-H2AX protein and activation of ATM/ATR signaling pathway. Cell death by TPEN was dependent on ROS generation as evidenced by the reversal of cell viability, and DNA damage and the abrogation of gamma-H2AX levels in the presence of antioxidants. Treatment with antioxidants, however, failed to reverse cytotoxicity at high TPEN concentrations (10uM). TPEN-induced cell death was also dependent on the redox cycling of copper since the copper chelator neocuproine inhibited DNA damage and reduced pChk1, gamma-H2AX, and ATM protein expression. Cell death by low TPEN concentrations, involved ATM/ATR signaling in all 3 cell lines, since pre-incubation with specific inhibitors of ATM and DNA-PK led to the recovery of cells from TPEN induced DNA damage. In addition, siRNA silencing of Chk1, DNA-PK and ATM abrogated the expression of gamma-H2AX and reversed cell death, suggesting that Chk1 and DNA-PK mediate TPEN-induced cytotoxicity in colon cancer cells. This study shows for the first time the involvement of Chk1, DNA-PK and ATM in TPEN induced DNA damage and confirms our previous findings that ROS generation and the redox cycling of copper in response to TPEN are the main mechanisms by which this compound induces cell death in human colon cancer cells. Inhibition of ATM or DNA PK did not reverse cytotoxicity at high TPEN concentrations that cause excessive levels of ROS and irreversible cellular damage. PMID- 27690732 TI - "The roots" of selenium toxicity: A new concept. AB - Elevated levels of selenium (Se) cause toxicity in non-accumulator plant species. The primary reasons for toxic Se effect have been considered to be selenoprotein accumulation and oxidative stress. However, based on our recent paper in Plant Cell Reports and previous literature data we suggest that disturbances in the homeostasis of both reactive oxygen and nitrogen species result in selenium induced nitro-oxidative stress, contributing to toxicity. The most characteristic symptom of Se exposure is the inhibited root elongation which is partly caused by hormonal disturbances. Our recent paper suggests the involvement of cytokinin in selenium stress sensing of the root systemAltogether, the aim of this Addendum is to present reactive nitrogen species and phytohormones as new players in plant selenium toxicity. PMID- 27690733 TI - Influence of diosmin on the metabolism and disposition of carbamazepine in healthy subjects. AB - 1. Carbamazepine (CBZ) is an antiepileptic drug with narrow therapeutic window and administration in humans receiving long-term therapy with diosmin (DSN) may occur, which leads to CYP3A4-mediated drug interactions. The purpose of the present study was to assess the influence of DSN on the metabolism and pharmacokinetics of CBZ in healthy volunteers. 2. An open-label, sequential, two period study was conducted in 12 healthy male volunteers. A single dose of DSN 500 mg was administered once daily for 10 days during treatment phase. A single dose of CBZ 200 mg was administered during control and after treatment phases under fasting conditions. The blood samples were collected after CBZ dosing at predetermined time intervals and analyzed by LC-MS/MS. 3. Treatment with DSN significantly enhanced the maximum plasma concentration (Cmax), area under the curve (AUC), half-life (t1/2) and significantly decreased the apparent oral clearance (CL/F) and elimination rate constant (Kel) of CBZ. On the other hand, treatment with DSN significantly decreased the Cmax and AUC of carbamazepine 10, 11-epoxide (CBZE). Furthermore, treatment with DSN significantly decreased the metabolite to parent ratios of Cmax and AUC, indicating the reduced metabolism of CBZ to CBZE. 4. The results suggest that the altered CYP3A4 enzyme activity and pharmacokinetics of CBZ might be attributed to DSN-mediated inhibition of CYP3A4 enzyme, which indicates pharmacokinetic interaction present between DSN and CBZ. Therefore, we conclude that DSN has an inhibiting effect on the metabolism and disposition of CBZ. PMID- 27690734 TI - Quality evaluation for the surveillance system of human prion diseases in China based on the data from 2010 to 2016. AB - The surveillance of CJD or human prion diseases (PrDs) has been conducted for 10 y in China. To evaluate the quality of China CJD surveillance system, the collections of the clinical and epidemiological information, the sampling, the clinical examinations and laboratory tests and follow-up survey were separately analyzed based on the data from 2010 to 2015. The obtaining rates of clinical information table, epidemiological-information table, sample inspection sheet and medical record of the referring patients from reporting units to the center of CJD surveillance maintained or reached at very high levels, being close to 100% in the past 3 y. 93.82%, 85.23%, 96.21% and 94.70% of the reported cases had the data of MRI, EEG, CSF 14-3-3 and PRNP sequencing, respectively. Follow-up surveys were conducted in about 50% cases in 2010 and 2011, 93.39% cases in 2012 and 100% cases in the last 3 y. High obtaining rates of the clinical and epidemiological data, high conducting rates of the relevant clinical examinations and laboratory tests, high performing rates of follow-up survey for every referring case reflect a good implemental capacity in China CJD surveillance system, which supplies solid basis for recognition and diagnosis of human prion diseases and guarantees good quality of China CJD surveillance system. PMID- 27690735 TI - Effectiveness of interventions to prevent motorcycle injuries: systematic review of the literature. AB - Globally, 49% of deaths from traffic crashes occur among vulnerable road users, including pedestrians, bicyclists, and motorcyclists. Approximately, a quarter of those killed are motorcyclists. The authors carried out a systematic review of the literature to evaluate the effectiveness of interventions to prevent motorcycle crashes and the associated morbidity and mortality. The studies included in this review provide evidence for the effectiveness of helmet use, protective clothing, training, and penalties for alcohol consumption and speeding in preventing injury and death to motorcyclists. The use of helmets is effective, especially if it is universally required by law for drivers and passengers. Training to obtain a license also has positive effects but not when it is totally voluntary. There is limited but consistent evidence that strengthening laws for penalties related to alcohol consumption or speeding has an impact on risk. Traffic calming interventions could help reduce crashes in urban areas. In jurisdictions where there is limited regulation or adherence to effective measures, such as the use of helmets, efforts should be directed primarily at expanding such practices. In other areas, efforts can focus on approaches based on alternative effective measures or on more innovative interventions adapted to local conditions. PMID- 27690737 TI - Targeting mTOR to reduce Alzheimer-related cognitive decline: from current hits to future therapies. AB - INTRODUCTION: The mTOR pathway is involved in the regulation of a wide repertoire of cellular functions in the brain and its dysregulation is emerging as a leitmotif in a large number of neurological disorders. In AD, altered mTOR signaling contributes to the inhibition of autophagy deposition of Abeta and tau aggregates and to the alteration of several neuronal metabolic pathways. Areas covered: In this review, we report all the current findings on the use of mTOR inhibitors (rapamycin, rapalogues) in the treatment of AD. These results support the role of mTOR inhibitors as potential therapeutic agents able to reduce AD hallmarks and recover cognitive performances. Expert commentary: Despite mTOR inhibitors appearing to be ideal compounds to counteract AD, further studies are needed in order to gain knowledge on the involvement of aberrant mTOR in AD, and to standardize a valuable therapeutic approach that can be translated to humans. PMID- 27690736 TI - The 3'-untranslated region of mRNAs as a site for ribozyme cleavage-dependent processing and control in bacteria. AB - Besides its primary informational role, the sequence of the mRNA (mRNA) including its 5'- and 3'- untranslated regions (UTRs), contains important features that are relevant for post-transcriptional and translational regulation of gene expression. In this work a number of bacterial twister motifs are characterized both in vitro and in vivo. The analysis of their genetic contexts shows that these motifs have the potential of being transcribed as part of polycistronic mRNAs, thus we suggest the involvement of bacterial twister motifs in the processing of mRNA. Our data show that the ribozyme-mediated cleavage of the bacterial 3'-UTR has major effects on gene expression. While the observed effects correlate weakly with the kinetic parameters of the ribozymes, they show dependence on motif-specific structural features and on mRNA stabilization properties of the secondary structures that remain on the 3'-UTR after ribozyme cleavage. Using these principles, novel artificial twister-based riboswitches are developed that exert their activity via ligand-dependent cleavage of the 3'-UTR and the removal of the protective intrinsic terminator. Our results provide insights into possible biological functions of these recently discovered and widespread catalytic RNA motifs and offer new tools for applications in biotechnology, synthetic biology and metabolic engineering. PMID- 27690738 TI - The small heat shock protein Hsp31 cooperates with Hsp104 to modulate Sup35 prion aggregation. AB - The yeast homolog of DJ-1, Hsp31, is a multifunctional protein that is involved in several cellular pathways including detoxification of the toxic metabolite methylglyoxal and as a protein deglycase. Prior studies ascribed Hsp31 as a molecular chaperone that can inhibit alpha-Syn aggregation in vitro and alleviate its toxicity in vivo. It was also shown that Hsp31 inhibits Sup35 aggregate formation in yeast, however, it is unknown if Hsp31 can modulate [PSI+] phenotype and Sup35 prionogenesis. Other small heat shock proteins, Hsp26 and Hsp42 are known to be a part of a synergistic proteostasis network that inhibits Sup35 prion formation and promotes its disaggregation. Here, we establish that Hsp31 inhibits Sup35 [PSI+] prion formation in collaboration with a well-known disaggregase, Hsp104. Hsp31 transiently prevents prion induction but does not suppress induction upon prolonged expression of Sup35 indicating that Hsp31 can be overcome by larger aggregates. In addition, elevated levels of Hsp31 do not cure [PSI+] strains indicating that Hsp31 cannot intervene in a pre-existing prion oligomerization cycle. However, Hsp31 can modulate prion status in cooperation with Hsp104 because it inhibits Sup35 aggregate formation and potentiates [PSI+] prion curing upon overexpression of Hsp104. The absence of Hsp31 reduces [PSI+] prion curing by Hsp104 without influencing its ability to rescue cellular thermotolerance. Hsp31 did not synergize with Hsp42 to modulate the [PSI+] phenotype suggesting that both proteins act on similar stages of the prion cycle. We also showed that Hsp31 physically interacts with Hsp104 and together they prevent Sup35 prion toxicity to greater extent than if they were expressed individually. These results elucidate a mechanism for Hsp31 on prion modulation that suggest it acts at a distinct step early in the Sup35 aggregation process that is different from Hsp104. This is the first demonstration of the modulation of [PSI+] status by the chaperone action of Hsp31. The delineation of Hsp31's role in the chaperone cycle has implications for understanding the role of the DJ-1 superfamily in controlling misfolded proteins in neurodegenerative disease and cancer. PMID- 27690739 TI - Neurocognition and inhibitory control in polysubstance use disorders: Comparison with alcohol use disorders and changes with abstinence. AB - INTRODUCTION: Intact neurocognition and early cognitive recovery during abstinence are important for substance use treatment outcome. Yet, little is known about them in the largest group of treatment seekers today, individuals with polysubstance use disorders (PSU). This study primarily contrasted PSU and individuals with an alcohol use disorder (AUD) on neurocognitive and inhibitory control measures and, secondarily, measured changes during abstinence in PSU. METHOD: At one month of abstinence from all substances except tobacco, 36 PSU and 69 AUD completed neurocognitive assessments of executive function, general intelligence, auditory-verbal learning/memory, visuospatial learning/memory/skills, processing speed, working memory, fine motor skills, and cognitive efficiency. The groups were also assessed on inhibitory control measures of self-reported impulsivity, risk-taking, and decision-making. Seventeen PSU repeated the assessments after approximately four months of abstinence. All cross-sectional and longitudinal analyses included smoking status as a possible confound. RESULTS: At baseline, PSU performed significantly worse than AUD on auditory-verbal memory and on an inhibitory control measure of impulsivity. Polysubstance users showed trends to worse performance than AUD on general intelligence, auditory-verbal learning, and a decision-making task. Between one and four months of abstinence, PSU showed significant improvements on several neurocognitive and inhibitory control measures. CONCLUSIONS: Polysubstance users exhibit distinct differences in neurocognition and inhibitory control compared to AUD. Between one and four months of abstinence, neurocognition and inhibitory control improve in PSU. This neurocognitive recovery in some domains of abstinent PSU is influenced by smoking status. These results underscore the clinical value of select methods to augment neurocognitive recovery in PSU through appropriate interventions. PMID- 27690740 TI - Effect of trait anxiety on cognitive test performance in adolescents with and without attention-deficit/hyperactivity disorder. AB - INTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD) and anxiety are frequently comorbid disorders associated with different types of abnormal performance on neuropsychological tests. Although some studies have shown that comorbid anxiety alters ADHD test performance, results inconsistently show both improvements and worsening of different abilities, with failures to replicate across different anxiety disorders. Alternatively, trait anxiety may reflect a more stable influence on ADHD test performance than various diagnosable anxiety disorders. METHOD: To better understand the possible enhancing or deleterious effects of anxiety on ADHD cognitive impairments, this study examined the effect of individual differences in trait anxiety measured by the Multidimensional Anxiety Scale for Children (MASC) on a battery of computerized, rapid-performance tests measuring attention and impulsivity-related performance in 98 Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV) Combined Subtype ADHD adolescents and 123 healthy controls. It was hypothesized that trait anxiety would attenuate response inhibition and attention deficits in ADHD. RESULTS: ADHD-diagnosed adolescents with higher trait anxiety performed better on indices of sustained attention, reaction time, and motor variability, and had altered overall test-performance strategy, while response inhibition was affected in both ADHD and non-ADHD. CONCLUSIONS: This study provides the first evidence that pathological levels of anxiety are not needed to see differences in ADHD neuropsychological test performance. Instead, mildly elevated trait anxiety confers a protective influence by reducing the degree of impairment seen in ADHD. These findings suggest that better performing ADHD adolescents might have optimized levels of cortical arousal, and raise new questions about how best to identify the neurobiological substrates responsible for the beneficial effects. PMID- 27690742 TI - The impact of administration order in studies of computerized neurocognitive assessment tools (NCATs). AB - Computerized neurocognitive assessment tools (NCATs) have become a common way to assess postconcussion symptoms. As there is increasing research directly comparing multiple NCATs to each other, it is important to consider the impact that order of test administration may have on the integrity of the results. This study investigates the impact of administration order in a study of four different NCATs; Automated Neuropsychological Assessment Metrics (ANAM4), CNS Vital Signs (CNS-VS), CogState, and Immediate Post-Concussion Assessment and Cognitive Test (ImPACT). A total of 272 healthy active duty Service Members were enrolled into this study. All participants were randomly assigned to take two of the four NCATs with order of administration counterbalanced. Analyses attempted to investigate the effect of administration order alone (e.g., Time 1 versus Time 2), the effect of administration order combined with the impact of the specific NCAT received at Time 1, and only the impact of the Time 1 NCAT on Time 2 score variability. Specifically, independent samples t tests were used to compare Time 1 and Time 2 scores within each NCAT. Additional t tests compared Time 1 to Time 2 scores with Time 2 scores grouped by the NCAT received at Time 1. One-way analysis of variance (ANOVA) was used to compare only an NCAT's Time 2 scores grouped by the NCAT received at Time 1. Cohen's d effect sizes were calculated for all comparisons. The results from this study revealed statistically significant order effects for CogState and CNS-VS, though with effect sizes generally indicating minimum practical value, and marginal or absent order effects for ANAM4 and ImPACT with no clinically meaningful implications. Despite finding minimal order effects, clinicians should be mindful of the impact of administering multiple NCATs in a single session. Future studies should continue to be designed to minimize the potential effect of test administration order. PMID- 27690743 TI - Empathising with the enemy: emotion regulation and support for humanitarian aid in violent conflicts. AB - Considering that negative intergroup emotions can hinder conflict resolution, we proposed integrative emotion regulation (IER) as possibly predicting conciliatory policies towards outgroups in violent conflict. Two studies examined Jewish Israelis' self-reported IER, empathy, liberal attitudes, and support for humanitarian aid to Palestinians in Gaza. Study 1 (N = 298) found that unlike reappraisal Jewish Israelis' ability to explore emotions (e.g. IER) promoted concern for others' emotions (empathy), which in turn predicted support for humanitarian aid (while controlling for education level, and religiosity). Study 2 (N = 291) replicated this mediation model, additionally confirming that liberal attitudes (upholding equal, fair treatment for minorities) moderated the relation between IER and support for humanitarian aid. Thus, IER linked more strongly with humanitarian support when the commitment for liberal egalitarian beliefs was high. Preliminary results hold important theoretical and practical implications regarding the potential to empathise with outgroup members in intractable conflicts. PMID- 27690744 TI - RigiScan data under long-term testosterone therapy: improving long-term blood circulation of penile arteries, penile length and girth, erectile function, and nocturnal penile tumescence and duration. AB - BACKGROUND: Late-onset hypogonadism (LOH) presents with low serum testosterone (TT) levels and sexual and nonsexual symptoms. Erectile dysfunction affects a man's self-esteem and as a result partner relationship and quality of life. OBJECTIVES: To investigate the andrological clinical profile outcomes of testosterone therapy (TTh) in men (n = 88) with symptomatic LOH complaints and symptoms. MAIN OUTCOME MEASURES: Erectile function was assessed using the International Index of Erectile Function-5 questionnaire at baseline and at 6 and 12 months of TTh. In addition, penile length was measured at baseline and 12 months. We also evaluated nocturnal penile tumescence (NPT, using RigiScan) and blood flow of cavernous arteries (penile Doppler ultrasonography) at baseline and 12 months of TT. MATERIALS AND METHODS: Eighty-eight LOH men (Mage 51.1 years) with erectile dysfunction, all with serum TT <10.4 nmol/L before TTh. Patients received intramuscular long-acting testosterone undecanoate for 12 months. RESULTS: Following TTh, in all patients, serum TT levels were restored within 3 months to normal levels. Compared with baseline values, erectile function significantly improved at 6 (mean score increase 1.95) and 12 months (mean score increase 2.16). No significant changes in penile length were observed. NPT significantly improved at 12 months in terms of both the frequency (mean increase 1.27 times) and duration of rigidity (mean increase 5.12 min). As regards the blood flow of the cavernous arteries, we observed a significant improvement (decrease of 1.16 cm/s) and end diastolic velocity of the penile arteries. CONCLUSION: TTh in men with LOH resulted in improvement of the erectile function, NPT, and to some extent the blood flow of the cavernous arteries. PMID- 27690746 TI - Cognitive risk factors explain the relations between neuroticism and social anxiety for males and females. AB - The hierarchical model of vulnerabilities to emotional distress contextualizes the relation between neuroticism and social anxiety as occurring indirectly through cognitive risk factors. In particular, inhibitory intolerance of uncertainty (IU; difficulty in uncertain circumstances), fear of negative evaluation (FNE; fear of being judged negatively), and anxiety sensitivity (AS) social concerns (fear of outwardly observable anxiety) are related to social anxiety. It is unclear whether these risk factors uniquely relate to social anxiety, and whether they account for the relations between neuroticism and social anxiety. The indirect relations between neuroticism and social anxiety through these and other risk factors were examined using structural equation modeling in a sample of 462 individuals (M age = 36.56, SD = 12.93; 64.3% female). Results indicated that the relations between neuroticism and social anxiety could be explained through inhibitory IU, FNE, and AS social concerns. No gender differences were found. These findings provide support for the hierarchical model of vulnerabilities to emotional distress disorders, although the cognitive risk factors accounted for variance beyond their contribution to the relation between neuroticism and social anxiety, suggesting a more complex model than that expressed in the hierarchical model of vulnerabilities. PMID- 27690745 TI - Within-session and one-week practice effects on a motor task in amnestic mild cognitive impairment. AB - Practice effects on neuropsychological tests, which are improvements in test scores due to repeated exposure to testing materials, are robust in healthy elders, but muted in older adults with cognitive disorders. Conversely, few studies have investigated practice effects on motor tasks involving procedural memory, particularly across test-retest periods exceeding 24 hours. The current study examined one-week practice effects on a novel upper extremity motor task in 54 older adults with amnestic mild cognitive impairment. Results indicate that these individuals with primary memory deficits did improve on this motor task within a brief training session as well as across one week. These practice effects were unrelated to demographic characteristics or global cognition. One week practice effects were, however, negatively related to delayed memory function, with larger practice effects being associated with poorer delayed memory and potentially better visuospatial ability. The presence of longer term practice effects on a procedural motor task not only has implications for how longitudinal assessments with similar measures involving implicit memory might be interpreted, but may also inform future rehabilitative strategies for patients with more severe declarative memory deficits. PMID- 27690747 TI - Use of Er:YAG for the treatment of recalcitrant facial verruca plana. AB - BACKGROUND: Recalcitrant facial verruca plana (FVP) may persist for years and full remission is not always achieved with conventional therapies. The clinical success rates reported for different lasers are highly variable and only one study evaluated the Er:YAG laser for the treatment of FVP. OBJECTIVE: To determine whether Er:YAG is safe and effective for the treatment of recalcitrant FVP. METHODS: Forty-six patients with recalcitrant FVP were treated by Er:YAG at four-week intervals. The patients' clinical response, adverse effects such as scarring and pigment change, recurrence and patient satisfaction were assessed. Patients were clinically evaluated after each session over a six-month follow-up. RESULTS: A total of 550 lesions of 46 participants were treated with 1-3 passes. The patients received 1-4 laser sessions with one session on average. Thirty-two patients (62.5%) achieved a complete response with 458 lesions (83.3%) being completely and 30 (5.5%) being partially healed. The post-treatment side effects were post-inflammatory hyperpigmentation and mild scar formation. FVP recurred in 12 patients (26.0%). Twenty-six patients (56.5%) were completely satisfied and nine (19.5%) were mostly satisfied with the treatment. CONCLUSIONS: Er:YAG laser is a good treatment option in patients with recalcitrant FVP, particularly for cosmetically sensitive areas. PMID- 27690748 TI - Neurological soft signs are associated with attentional dysfunction in children with attention deficit hyperactivity disorder. AB - INTRODUCTION: Inattention is one of the core symptoms of Attention Deficit Hyperactivity Disorder (ADHD). Most of patients with ADHD show motor impairment, consisting in the persistence of neurological soft signs (NSS). Our aim was to evaluate attentional and motor functioning in an ADHD sample and healthy children (HC) and possible link between attentional dysfunction and motor impairment in ADHD. METHOD: Twenty-seven drug-naive patients with ADHD and 23 HC were tested with a test battery, measuring different aspects of attention. Motor evaluation has provided three primary variables: overflow movements (OM), dysrhythmia and total speed of timed activities. RESULTS: Compared to HC, patients were impaired in a considerable number of attentional processes and showed a greater number of NSS. Significant correlations between disturbances of attention and motor abnormalities were observed in ADHD group. CONCLUSION: Our findings suggest that attentional processes could be involved in the pathophysiology of the NSS and add scientific evidence to the predictive value of NSS as indicators of the severity of functional impairment in ADHD. Given the marked improvement or complete resolution of NSS following treatment with methylphenidate, we suggest that evaluation of NSS is useful to monitor the effectiveness of pharmacological treatment with MPH in ADHD.

However, controversy exists regarding the best method of training this characteristic. This study sought to determine the most effective core training method to enhance distal limb athleticism. A total of 12 participants (24 +/- 3 years, 1.8 +/- 0.05 m, 76.8 +/- 9.7 kg) consisting of Muay Thai athletes performed a core training protocol (Isometric vs. Dynamic, with Control) for 6 weeks, using a repeated measures design to assess performance (peak strike velocity, peak impact force, muscular activation) in various strikes. Isometric training increased impact force in Jab (554.4 +/- 70.1 N), Cross (1895.2 +/- 203.1 N), Combo (616.8 +/- 54.9 N), and Knee (1240.0 +/- 89.1 N) trials (P < 0.05). Dynamic training increased strike velocity in Jab (1.3 +/- 0.2 m . s-1), Cross (5.5 +/- 0.9 m . s 1), Combo (0.7 +/- 0.1, 2.8 +/- 0.3 m . s-1), and Knee (3.2 +/- 0.3 m . s-1) trials (P < 0.05). Isometric training increased Combo impact force 935.1 +/- 100.3 N greater than Dynamic and 931.6 +/- 108.5 N more than Control (P < 0.05). Dynamic training increased Jab strike velocity 1.3 +/- 0.1 m . s-1 greater than Isometric and 0.8 +/- 0.1 m . s-1 more than Control (P < 0.05). It appears that both static and dynamic approaches to core training are needed to enhance both velocity and force in distal limbs.

AB - Research shows a positive relationship between women's empowerment and reproductive health. Yet we know little about the quantitative relationship between women's agency and contraceptive use. We conducted a systematic review of peer-reviewed literature assessing the link between women's decision-making and freedom of movement with their contraceptive use in lower- and middle-income countries. Of 102 articles that met the initial screening criteria, 12 met all inclusion and exclusion criteria. Of the 12 included studies, consistently positive associations with contraceptive use were found in those that measured decision-making and freedom of movement as separate constructs. Composite measures had a less clear relationship with contraceptive use. In conclusion, women's agency is associated with women's contraceptive use in lower- and middle income countries. However, the relationship is sensitive to how agency and its components are measured. Our review suggests the need for consistent validation of scales for women's agency as well as more rigorous research using standardised and validated scales, when possible. Longitudinal and intervention studies in lower- and middle-income countries will be useful for understanding the causal impact of women's agency on contraceptive use, and will help to inform policies and programmes to increase contraceptive use in these settings. PMID- 27690751 TI - The relationship between sleep and working memory in children with neurological conditions. AB - The objective of this study is to investigate whether sleep problems might account for the increased working memory deficits observed in school-aged children with neurological conditions. A novel, transdiagnostic approach to the investigation was chosen, and sleep is treated as a process that can potentially account for working memory difficulties across a range of neurological conditions. Prevalence estimates of sleep problems are also examined. Archival data of 237 children aged 6 to 11 years were collected from a Western Australian statewide neuropsychological service for the period 26 July 2011 to 14 January 2014. Measures of parent-reported sleep quality, snoring, and daytime sleepiness were obtained, in addition to objective measures of verbal and spatial working memory, storage capacity, and processing speed. The results of the data analysis reveal that over one third of participants reported having clinically-significant levels of sleep problems and that poor sleep quality is significantly associated with verbal working memory difficulties. This association remains after partialling out the variance contributed to performance by storage capacity and processing speed, suggesting that sleep is impacting upon an executive component of working memory. No other significant associations are observed. The results suggest that poor sleep quality is associated with an executive component of verbal (rather than spatial) working memory in children with neurological conditions. This has implications for the biological mechanisms thought to underlie the relationship between sleep and cognition in children. The results also demonstrate the clinical utility of a transdiagnostic approach when investigating sleep and cognition in children with neurological conditions. PMID- 27690741 TI - Two Phase 3 Trials of Dupilumab versus Placebo in Atopic Dermatitis. AB - BACKGROUND: Dupilumab, a human monoclonal antibody against interleukin-4 receptor alpha, inhibits signaling of interleukin-4 and interleukin-13, type 2 cytokines that may be important drivers of atopic or allergic diseases such as atopic dermatitis. METHODS: In two randomized, placebo-controlled, phase 3 trials of identical design (SOLO 1 and SOLO 2), we enrolled adults with moderate-to-severe atopic dermatitis whose disease was inadequately controlled by topical treatment. Patients were randomly assigned in a 1:1:1 ratio to receive, for 16 weeks, subcutaneous dupilumab (300 mg) or placebo weekly or the same dose of dupilumab every other week alternating with placebo. The primary outcome was the proportion of patients who had both a score of 0 or 1 (clear or almost clear) on the Investigator's Global Assessment and a reduction of 2 points or more in that score from baseline at week 16. RESULTS: We enrolled 671 patients in SOLO 1 and 708 in SOLO 2. In SOLO 1, the primary outcome occurred in 85 patients (38%) who received dupilumab every other week and in 83 (37%) who received dupilumab weekly, as compared with 23 (10%) who received placebo (P<0.001 for both comparisons with placebo). The results were similar in SOLO 2, with the primary outcome occurring in 84 patients (36%) who received dupilumab every other week and in 87 (36%) who received dupilumab weekly, as compared with 20 (8%) who received placebo (P<0.001 for both comparisons). In addition, in the two trials, an improvement from baseline to week 16 of at least 75% on the Eczema Area and Severity Index was reported in significantly more patients who received each regimen of dupilumab than in patients who received placebo (P<0.001 for all comparisons). Dupilumab was also associated with improvement in other clinical end points, including reduction in pruritus and symptoms of anxiety or depression and improvement in quality of life. Injection-site reactions and conjunctivitis were more frequent in the dupilumab groups than in the placebo groups. CONCLUSIONS: In two phase 3 trials of identical design involving patients with atopic dermatitis, dupilumab improved the signs and symptoms of atopic dermatitis, including pruritus, symptoms of anxiety and depression, and quality of life, as compared with placebo. Trials of longer duration are needed to assess the long-term effectiveness and safety of dupilumab.

PMID- 27690753 TI - Cytochrome P450 2W1 (CYP2W1) - ready for use as the biomarker and drug target for cancer? AB - 1. This article aims to evaluate the potentials of using cytochrome P450 2W1 (CYP2W1) as a biomarker and a drug target of cancer because of its characteristic cancer-specific expression. 2. Discrepant findings comparing the expression levels of CYP2W1 in cancer and non-cancer samples were reported. In general, the expression followed a developmental pattern. The demethylation status of CpG island and the expression levels of CYP2W1 genes was positively correlated. 3. CYP2W1 was able to activate several procarcinogens, anticancer pro-drugs and to metabolise many endogenous substances including fatty acids and lysophospholipids. 4. CYP2W1 expression level was suggested to serve as an independent prognostic biomarker in colorectal cancer and hepatocellular carcinoma. The correlation of genetic polymorphisms of CYP2W1 and cancer risk was uncertain. 5. Further characterisation of CYP2W1 structure is suggested to link to its functions. More studies are warranted to reveal the true status and the regulation of CYP2W1 expression across normal and cancer tissues. Catalytic activity of CYP2W1 should be tested on a wider spectrum of endogenous and exogenous substances before its use as the drug target. Larger size of clinical samples can be included to verify the potential of CYP2W1 as the prognostic or cancer risk biomarker. PMID- 27690752 TI - Multicomponent analysis of a digital Trail Making Test. AB - OBJECTIVE: The purpose of the current study was to use a newly developed digital tablet-based variant of the TMT to isolate component cognitive processes underlying TMT performance. METHOD: Similar to the paper-based trail making test, this digital variant consists of two conditions, Part A and Part B. However, this digital version automatically collects additional data to create component subtest scores to isolate cognitive abilities. Specifically, in addition to the total time to completion and number of errors, the digital Trail Making Test (dTMT) records several unique components including the number of pauses, pause duration, lifts, lift duration, time inside each circle, and time between circles. Participants were community-dwelling older adults who completed a neuropsychological evaluation including measures of processing speed, inhibitory control, visual working memory/sequencing, and set-switching. The abilities underlying TMT performance were assessed through regression analyses of component scores from the dTMT with traditional neuropsychological measures. RESULTS: Results revealed significant correlations between paper and digital variants of Part A (rs = .541, p < .001) and paper and digital versions of Part B (rs = .799, p < .001). Regression analyses with traditional neuropsychological measures revealed that Part A components were best predicted by speeded processing, while inhibitory control and visual/spatial sequencing were predictors of specific components of Part B. Exploratory analyses revealed that specific dTMT-B components were associated with a performance-based medication management task. CONCLUSIONS: Taken together, these results elucidate specific cognitive abilities underlying TMT performance, as well as the utility of isolating digital components. PMID- 27690754 TI - The location of the tibial accelerometer does influence impact acceleration parameters during running. AB - Tibial accelerations have been associated with a number of running injuries. However, studies attaching the tibial accelerometer on the proximal section are as numerous as those attaching the accelerometer on the distal section. This study aimed to investigate whether accelerometer location influences acceleration parameters commonly reported in running literature. To fulfil this purpose, 30 athletes ran at 2.22, 2.78 and 3.33 m . s-1 with three accelerometers attached with double-sided tape and tightened to the participants' tolerance on the forehead, the proximal section of the tibia and the distal section of the tibia. Time-domain (peak acceleration, shock attenuation) and frequency-domain parameters (peak frequency, peak power, signal magnitude and shock attenuation in both the low and high frequency ranges) were calculated for each of the tibial locations. The distal accelerometer registered greater tibial acceleration peak and shock attenuation compared to the proximal accelerometer. With respect to the frequency-domain analysis, the distal accelerometer provided greater values of all the low-frequency parameters, whereas no difference was observed for the high frequency parameters. These findings suggest that the location of the tibial accelerometer does influence the acceleration signal parameters, and thus, researchers should carefully consider the location they choose to place the accelerometer so that equivalent comparisons across studies can be made. PMID- 27690755 TI - Steady states and outbreaks of two-phase nonlinear age-structured model of population dynamics with discrete time delay. AB - In this paper we study the nonlinear age-structured model of a polycyclic two phase population dynamics including delayed effect of population density growth on the mortality. Both phases are modelled as a system of initial boundary values problem for semi-linear transport equation with delay and initial problem for nonlinear delay ODE. The obtained system is studied both theoretically and numerically. Three different regimes of population dynamics for asymptotically stable states of autonomous systems are obtained in numerical experiments for the different initial values of population density. The quasi-periodical travelling wave solutions are studied numerically for the autonomous system with the different values of time delays and for the system with oscillating death rate and birth modulus. In both cases it is observed three types of travelling wave solutions: harmonic oscillations, pulse sequence and single pulse. PMID- 27690756 TI - Resolution of a disputed albendazole result in the UK Official Control System - time for more guidance? AB - Albendazole, one of the benzimidazole anthelmintics, is used in ruminants and has maximum residue limits in muscle, fat and other tissue owing to reported teratogenicity. Albendazole is extensively metabolised in domestic animals and humans with rapid conversion to a sulphoxide and subsequently sulphone and amino sulphone metabolites. Sulphoxide metabolites are responsible for the systemic biological activity of benzimidazole drugs. Herein we report a case of disputed results for albendazole in a consignment sampled at import in which the Official Analyst certified against the consignment for excess albendazole. A laboratory acting for the importer reported data below the MRL, including a finding of the parent drug which is not included in the residue definition. The Government Chemist has a statutory duty as a route of technical appeal in the UK Official Food Control system and the case was referred for referee analysis. We report our findings based on a LC-MS/MS method, which confirmed the official findings, did not reveal the presence of the parent drug but identified hot spots of albendazole marker residues in the consignment. We discuss the need for recommendations on official sampling at import and interpretation of results. PMID- 27690757 TI - Correlates of influenza vaccine uptake among community-dwelling older adults in Brazil. AB - This study aimed at assessing the factors associated with vaccine uptake in a representative sample of community-dwelling Brazilian older adults, specifically focusing on differences in socioeconomic factors among the country regions. We conducted a cross-sectional, population-based study, using a probabilistic household sample in 2013. Individuals aged 60 years or more answered a structured questionnaire informing on vaccination status and sociodemographic and behavioral covariates. Associations between variables were evaluated using prevalence ratios estimated by Poisson regression models. The overall vaccination coverage (72.6%) in older adults ranked lower than the goal of 80% stipulated by the Brazilian health authority; vaccine uptake differed significantly among the country regions. The prevalence of vaccination was lower in black individuals in Brazil than that in their white counterparts. The prevalence of vaccine uptake was significantly associated with covariates on current life style, use of health care, and socioeconomic determinants. Compared with individuals with 0-3 years of education, more schooled individuals had higher prevalence of vaccine uptake in the North, Northeast, and South regions of the country. This study showed that there is room for increasing vaccination coverage among the elderly in Brazil. The knowledge previously obtained on factors significantly associated with vaccine uptake has not prevented them to continue influencing this outcome. The socioeconomic inequality in vaccination in some Brazilian regions reinforces the need of targeting the intervention toward the most vulnerable groups. PMID- 27690758 TI - An effective self-control strategy for the reduction of aflatoxin M1 content in milk and to decrease the exposure of consumers. AB - The study reports the results of testing the sensitivity of an early warning sampling plan for detecting milk batches with high aflatoxin AFM1 concentration. The effectiveness of the method was investigated by the analysis of 9017 milk samples collected in Italian milk processing plants that applied control plans with different action limits (AL). For those milk processing plants where 30 ng kg-1 AL has been applied, the AFM1 contamination was significantly lower at or above the 95th percentile of the milk samples when compared with plants that used 40 ng kg-1 AL. The results show that the control plan can be used effectively for early warning of occurrence of high AFM1 contamination of milk and to carry out pro-active measures to limit the level of contamination. Estimation of dietary exposure was also carried out, based on the aflatoxin M1 content of the milk samples and on Italian food consumption data. Estimated Daily Intakes (EDI) and Hazard Indices (HI) were calculated for different age groups of the population. HIs show that no adverse effects are expected for the adult population, but in the case of children under age three, the approximate HI values were considerably higher. This underlines the importance of the careful monitoring and control of aflatoxin M1 in milk and dairy products. PMID- 27690759 TI - Body dissatisfaction in women's artistic gymnastics: A longitudinal study of psychosocial indicators. AB - Body dissatisfaction is prevalent in women's artistic gymnastics (WAG). Cross sectional research points to social and individual risk factors, however it does not account for potential changes in body dissatisfaction during an athletic season. This study aimed to determine how gymnasts' body dissatisfaction, risk factors for eating disorders, media internalisation, perfectionism and mood state change during pre-competition, competition and post-competition seasons and to identify how these psychosocial indicators impact on body dissatisfaction during the athletic year. The sample consisted of 20 Brazilian elite women's artistic gymnasts aged 10-16 years. Data were obtained from a 9-month study using: Body Shape Questionnaire (BSQ); Eating Attitude Test-26; Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3); Multidimensional Perfectionism Scale (MPS); Brunel Mood Scale (BRUMS) and triceps and subscapular skinfolds. Body dissatisfaction was higher during the competition season and disordered eating, perfectionism and vigour values were higher in the pre-competition season. Disordered eating has been found as the strongest predictor of body dissatisfaction during all seasons, and mood state partly contributed to body dissatisfaction in the competitive season. Stakeholders should understand that body dissatisfaction and the prevalence of disordered eating may change over time. PMID- 27690760 TI - Residue analysis of thyreostats in baby foods via matrix solid phase dispersion and liquid chromatography - dual-polarity electrospray - tandem mass spectrometry. AB - This paper describes a rapid method for confirming residues of thyreostats in meat-based baby foods by using liquid chromatography - dual polarity electrospray - tandem mass spectrometry (LC-ES(+/-)-MS/MS). Six thioureylenes, belonging to the group of thiouracil and imidazole, were selected for this work: thiouracil (TU), methylthiouracil (MTU), propylthiouracil (PTU), phenylthiouracil (PhTU), mercaptobenzimidazole (MBI) and tapazole (TAP). The amphoteric nature of these compounds allows their electrospray detection in both positive and negative ionisation. Nevertheless, MS detection is not favoured by their low molecular weights, while their chromatographic retention is also thwarted by their high polarity. A pentafluorophenyl (PFP) core-shell phase column was selected to avoid peak asymmetry or peak splitting, and a dual-polarity ionisation method was optimised to obtain a sensitivity as high as possible. The method was validated according to the Commission Decision 657/2002/EC. A simple and fast procedure based on matrix solid phase dispersion (MSPD) was optimised to extract analytes from baby foods with recoveries exceeding 82%. Limit of decision (CCalpha) and detection capability (CCbeta) were lower than the permissible maximum concentration (10 ng g-1). The validated method was then applied to assess the potential occurrence of the six selected thyreostats in nine commercial products. All the samples were found free of contamination. PMID- 27690761 TI - The effect of natural and built environmental characteristics on pedestrian vehicle crash severity in Ghana. AB - Despite the benefits of walking as a means of travelling, walking can be quite hazardous. Pedestrian-vehicle crashes remain a major concern in Ghana as they account for the highest percentage of fatalities. The objective of this study is to determine the effect of both natural and built environmental features on pedestrian-vehicle crash severity in Ghana. The study is based on an extensive pedestrian-vehicle crash dataset extracted from the National Road Traffic Accident Database at the Building and Road Research Institute (BRRI) of the Council for Scientific and Industrial Research (CSIR), Ghana. Using a multinomial logit modelling framework, possible determinants of pedestrian-vehicle crash severity were identified. The study found that fatal crashes are likely to occur during unclear weather conditions, on weekends, at night time where there are no lights, on curved and inclined roads, on untarred roads, at mid-blocks and on wider roads. The developed model and its interpretations will make important contributions to road crash analysis and prevention in Ghana with the possibility of extension to other developing countries. These contributing factors could inform policy makers on road design and operational improvements. PMID- 27690764 TI - Editorial: Final Musings on the Impact of Molecular Endocrinology.

PMID- 27690762 TI - Immunogenicity of AS03-adjuvanted and non-adjuvanted trivalent inactivated influenza vaccines in elderly adults: A Phase 3, randomized trial and post-hoc correlate of protection analysis. AB - In this study we describe the immunogenicity results from a subset of older people (N = 5187) who participated in a Phase 3 randomized, observer-blinded trial of AS03-TIV versus TIV (FluarixTM) (ClinicalTrials.gov, NCT00753272). Participants received one dose of AS03-TIV or TIV in each study year and antibody titers against the vaccine strains were assessed using hemagglutination inhibition (HI) assay at 21 d and 180 d post-vaccination in each vaccine group in the 2008/09 (Year 1) and 2009/10 (Year 2) influenza seasons. Manufacturing consistency of 3 lots of AS03-TIV for HI antibody responses in Year 1 was a co primary objective. In a post-hoc analysis, a statistical regression model included 4830 subjects in whom immunogenicity and laboratory-confirmed attack rate data were available; the analysis was performed to assess HI antibody titers against A/H3N2 as a correlate of protection for laboratory-confirmed A/H3N2 influenza. AS03-TIV and TIV elicited strong HI antibody responses against each vaccine strain 21 d post-vaccination in both years. The manufacturing consistency of 3 lots of AS03-TIV was demonstrated. In both years and each vaccine group, HI antibody responses were lower for A/H1N1 than the other vaccine strains. Day 180 seroconversion rates (proportion with >=4-fold increase in titer compared with pre-vaccination titer) in Year 1 in the AS03-TIV and TIV groups, respectively, were 87.7% and 74.1% for A/H3N2, 69.7% and 59.6% for influenza B, and 58.3% and 47.4% for A/H1N1. The post-hoc statistical model based on A/H3N2 attack rates and HI antibody titers estimated that a 4-fold increase in post-vaccination titers against A/H3N2 was associated with a 2-fold decrease in the odds of A/H3N2 infection.

PMID- 27690831 TI - Quercetin attenuates neuronal autophagy and apoptosis in rat traumatic brain injury model via activation of PI3K/Akt signaling pathway. AB - OBJECTIVE: Neuronal autophagy and apoptosis play an irreplaceable role in brain injury pathogenesis and may represent a hopeful target for treatment. Previous studies have demonstrated that administration of quercetin-attenuated brain damage in a variety of brain injury models including traumatic brain injury (TBI). However, whether PI3K/Akt signaling pathway mediates the neuroprotection of quercetin following TBI is not well clarified. We sought to propose a hypothesis that quercetin could attenuate neuronal autophagy and apoptosis via enhancing PI3K/Akt signaling. METHODS: All rats were randomly arranged into four groups as follows: sham group (n = 25), TBI group (n = 25), TBI + quercetin group (n = 25), TBI + quercetin + LY294002 group (n = 25). Quercetin (Sigma, USA, dissolved in 0.9% saline solution) was administered intraperitoneally at a dose of 50 mg/kg at 30 min, 12 h, and 24 h after TBI. The neurological impairment and spatial cognitive function was assessed by the neurologic severity score and Morris water maze, respectively. Immunohistochemistry staining and western blotting was used to evaluate the expression of LC3, p-Akt, caspase-3, Bcl-2, and Bax. RESULTS: Quercetin treatment significantly attenuated TBI-induced neurological impairment (1-3 days, p < 0.05) and improved cognitive function (5-8 days, p < 0.05). Double immunolabeling demonstrated that quercetin significantly reduced the LC3-positive cells co-labeled with NeuN, whereas significantly enhanced p-Akt-positive cells co-labeled with NeuN. Furthermore, quercetin treatment reduced the expression of LC3,caspase-3 and Bax levels induced following TBI (p < 0.05), and increased the expression of p-Akt and Bcl-2 at 48 h (p < 0.05). CONCLUSION: In conclusion, our observations indicate that post-injury treatment with quercetin could inhibit neuronal autophagy and apoptosis in the hippocampus in a rat model of TBI. The neuroprotective effects of quercetin may be related to modulation of PI3K/Akt signaling pathway. PMID- 27690832 TI - Intraoral extraction of an ectopic mandibular third molar detected in the subcondylar region without a pathological cause: A case report and literature review. AB - PURPOSE: To present a case report on the presence of an ectopic mandibular third molar (EMTM), the surgical treatment, and outcome. CASE REPORT: A 63-year-old woman presented with right preauricular facial swelling, limited jaw function, and pain. Radiographic assessment demonstrated an EMTM positioned in the superoposterior aspect of the ramus. Radiographically, there was a bony tunnel extending from the third molar to distal of the second molar. The patient was treated by an intraoral approach on the medial aspect of the ramus for removal of the ectopic third molar, as well as the tissue in the bony tunnel. RESULTS: The patient healed uneventfully. The soft tissue in the bony canal was granulation tissue, and nerve function was preserved. A literature search of EMTMs was conducted identifying 17 reported cases. CONCLUSION: Three-dimensional imaging in the management of EMTM can be beneficial in identifying position of the tooth, associated pathology, and identifying the position of neurovascular structures to aid in removal of the ectopic tooth.

PMID- 27690834 TI - Whiplash Injury or Concussion? A Possible Biomechanical Explanation for Concussion Symptoms in Some Individuals Following a Rear-End Collision. AB - Study Design Finite element modeling of experimental data. Background The clinical presentations of whiplash injury and concussion have considerable overlap. Both diagnoses are generally based on presenting signs and symptoms, and a history of neck or head trauma. With incomplete knowledge of the trauma, differentiating between whiplash injury and concussion can be clinically challenging. Objectives To estimate the brain strains that develop during rear end car crashes, evaluate how these strains vary with different head kinematic parameters, and compare these strains to those generated during potentially concussive football helmet impacts. Methods Head kinematic data were analyzed from 2 prior studies, one that focused on head restraint impacts in rear-end crash tests and another that focused on football helmet impacts. These data were used as inputs to a finite element model of the human brain. Brain strains were calculated and compared to different peak kinematic parameters and between the 2 impact conditions. Results Brain strains correlated best with the head's angular velocity change for both impact conditions. The 4 crashes with head angular velocity changes greater than 30 rad/s (greater than 1719 degrees /s) generated the highest brain stains. One crash, in which the head wrapped onto the top of the head restraint, generated brain strains similar to a 9.3-m/s rear football helmet impact, a level previously associated with concussion. Conclusion This work provides new insight into a potential biomechanical link between whiplash injury and concussion, and advances our understanding of how head restraint interaction during a rear-end crash may cause an injury more typically associated with sports-related head impacts.

PMID- 27690835 TI - MicroRNA 320a Predicts Chronic Axial and Widespread Pain Development Following Motor Vehicle Collision in a Stress-Dependent Manner. AB - Study Design Prospective human cohort study combined with molecular studies. Background A microRNA is a small, noncoding RNA molecule that can play a role in disease onset. Recent studies found that circulating levels of microRNA 320a (miR 320a) are associated with musculoskeletal pain conditions and that miR-320a is stress responsive. Objectives To investigate whether circulating expression levels of miR-320a in the peritraumatic period predict persistent axial musculoskeletal pain 6 months after motor vehicle collision (MVC). Methods We evaluated whether (1) circulating miR-320a and related members of the miR-320a family predict axial musculoskeletal pain and other musculoskeletal pain outcomes 6 months following MVC, and (2) miR-320a regulates stress system and pain-related transcripts in cell culture. Given the wealth of data suggesting that biological mechanisms influencing pain outcomes are often sex and/or stress dependent, interactions between miR-320a, stress, and sex were evaluated. Results In primary analyses (n = 69), a significant crossover interaction was observed between the influence of circulating miR-320a and peritraumatic distress (beta = -0.01, P = .002) on post-MVC axial musculoskeletal pain. Reduced peritraumatic miR-320a expression levels predicted axial musculoskeletal pain in distressed individuals (beta = -0.12, P = .006) but not nondistressed individuals. In secondary analyses, miR-320a predicted widespread musculoskeletal pain, and related members of the miR-320a family also predicted axial and widespread musculoskeletal pain. In cell culture, miR-320a bound stress and pain-associated 3'UTR transcripts (FKBP5, ADCYAP1, PER2, and NR3C1). Conclusion These data suggest that miR-320a may help mediate regional and widespread changes in pain sensitivity after MVC. J Orthop Sports Phys Ther 2016;46(10):911-919. doi:10.2519/jospt.2016.6944. PMID- 27690836 TI - Advancements in Imaging Technology: Do They (or Will They) Equate to Advancements in Our Knowledge of Recovery in Whiplash? AB - Synopsis It is generally accepted that up to 50% of those with a whiplash injury following a motor vehicle collision will fail to fully recover. Twenty-five percent of these patients will demonstrate a markedly complex clinical picture that includes severe pain-related disability, sensory and motor disturbances, and psychological distress. A number of psychosocial factors have shown prognostic value for recovery following whiplash from a motor vehicle collision. To date, no management approach (eg, physical therapies, education, psychological interventions, or interdisciplinary strategies) for acute whiplash has positively influenced recovery rates. For many of the probable pathoanatomical lesions (eg, fracture, ligamentous rupture, disc injury), there remains a lack of available clinical tests for identifying their presence. Fractures, particularly at the craniovertebral and cervicothoracic junctions, may be radiographically occult. While high-resolution computed tomography scans can detect fractures, there remains a lack of prevalence data for fractures in this population. Conventional magnetic resonance imaging has not consistently revealed lesions in patients with acute or chronic whiplash, a "failure" that may be due to limitations in the resolution of available devices and the use of standard sequences. The technological evolution of imaging techniques and sequences eventually might provide greater resolution to reveal currently elusive anatomical lesions (or, perhaps more importantly, temporal changes in physiological responses to assumed lesions) in those patients at risk of poor recovery. Preliminary findings from 2 prospective cohort studies in 2 different countries suggest that this is so, as evidenced by changes to the structure of skeletal muscles in those who do not fully recover. In this clinical commentary, we will briefly introduce the available imaging decision rules and the current knowledge underlying the pathomechanics and pathophysiology of whiplash. We will then acknowledge known prognostic factors underlying functional recovery. Last, we will highlight emerging evidence regarding the pathobiology of muscle degeneration/regeneration, as well as advancements in neuroimaging and musculoskeletal imaging techniques (eg, functional magnetic resonance imaging, magnetization transfer imaging, spectroscopy, diffusion-weighted imaging) that may be used as noninvasive and objective complements to known prognostic factors associated with whiplash recovery, in particular, poor functional recovery.

AB - A 51-year-old man presented to a direct-access physical therapy clinic with persistent neck pain for 5 days after a fall in shallow water while surfing. Based on "dangerous mechanism of injury" from the Canadian cervical spine rule as being a high risk factor, the physical therapist ordered radiographs of the cervical spine, which were suggestive of a more serious injury. Computed tomography suggested and magnetic resonance imaging confirmed vertebral artery dissection. J Orthop Sports Phys Ther 2016;46(10):929. doi:10.2519/jospt.2016.0416. PMID- 27690838 TI - Whiplash-Associated Disorders: Occupant Kinematics and Neck Morphology. AB - Synopsis Despite considerable research effort, the incidence of whiplash injury during automotive collisions has continued to rise. This is due, at least in part, to a limited recognition of biomechanical injury mechanisms and factors influencing injury risk. While automotive safety modifications reduced injury risk in some cases, impact on the overall whiplash incidence was limited. This is likely attributable to significant occupant-related differences that have a profound impact on injury risk. Many of those differences were outlined in research studies, and examples include female sex and the associated sex-based anthropometrical variation that can affect seating orientation; cervical spinal posture; and anatomical attributes, including cervical column slenderness and neck muscle morphometry. This review highlights these anatomical attributes and explains, based on biomechanical concepts, the method by which these attributes may alter cervical spine response during automotive rear impacts to affect injury risk. The biomechanical explanations are based on existing studies that have incorporated postmortem human subjects, computational models, and anthropomorphic test devices (ie, crash test dummies), as well as medical imaging in human volunteers. These biomechanical explanations may provide improved understanding of injury risk. J Orthop Sports Phys Ther 2016;46(10):834-844. doi:10.2519/jospt.2016.6846. PMID- 27690839 TI - Preventable Injuries/Fatalities Due to Distracted Driving: A Call for a Coordinated Action. AB - In the past decade, distracted driving has emerged as one of the most prominent global road safety concerns. The singular and combined efforts of many organizations, such as Drop It And Drive (DIAD) and the Traffic Injury Research Foundation (TIRF), have identified the need for partnerships, shared information, and access to interpretable research findings to guide decision making and to identify effective strategies to reduce, if not eliminate, preventable injuries/fatalities from distracted driving, including whiplash-associated disorders. This editorial describes activities in 5 target areas identified in our environmental scan in Canada: (1) provincial/territorial government strategies, (2) enforcement, (3) data collection and measurement, (4) awareness campaigns, and (5) legislation. We will also reinforce the potential benefits of seeking and establishing meaningful interdisciplinary partnerships to reduce distracted driving across the globe. Finally, this editorial provides an example of how these interdisciplinary partnerships can help reduce preventable, life altering injuries/deaths caused by distracted driving.

AB - There have been many advances in the management of neck pain disorders, but a personal frustration as a clinician and researcher in the field is that the incidence of full recovery following a whiplash injury as a result of a motor vehicle crash has not increased and, subsequently, the rate of transition to chronic neck pain has not lessened. The commentaries in this special issue reflect the multifaceted nature of whiplash-associated disorders and the wide ranging research in the field. While management of whiplash, especially the challenge of lessening the rate of transition to chronicity, has yet to be achieved, the picture is becoming clearer. This should give great confidence and some hope to individuals with whiplash-associated disorders who have long-term pain and functional disability that after the next decade of research and clinical development, the outcomes following whiplash are likely to be vastly improved.

PMID- 27690842 TI - Distinction of clenbuterol intake from drug or contaminated food of animal origin in a controlled administration trial - the potential of enantiomeric separation for doping control analysis. AB - The differentiation of clenbuterol abuse and unintentional ingestion from contaminated meat is crucial with respect to the valuation of an adverse analytical finding in human sports doping control. The proportion of the two enantiomers of clenbuterol may serve as potential discriminating parameter. For the determination of the individual enantiomers, specific methods were developed and validated for the different matrices under investigation based on chiral chromatography coupled to tandem mass spectrometry. Data are presented from the administration to humans of clenbuterol from a pharmaceutical preparation, and from cattle meat and liver containing residues. A shift in the proportion of the enantiomers in cattle meat is detected and this signature is also found in human urine after ingestion. Thus, an altered enantiomeric composition of clenbuterol may be used to substantiate athletes' claims following adverse analytical findings in doping control. However, in meat, the enantiomeric composition was found to be highly variable. Species as well as tissue dependent variances need to be considered in interpreting enantiomer discrimination. Analysis of post administration urines from a controlled experiment comparing the administration of racemic clenbuterol from a registered pharmaceutical preparation and the administration of residue-containing meat and liver (nonracemic mixture) from treated animals is reported. Furthermore doping control samples from Mexican U17 World Championship 2011 of the Federation Internationale de Football Association (FIFA), with adverse analytical findings for clenbuterol, were re-analysed. PMID- 27691050 TI - Probing the interaction of thionine with human serum albumin by multispectroscopic studies and its in vitro cytotoxic activity toward MCF-7 breast cancer cells. AB - The studies on protein-dye interactions are important in biological process and it is regarded as vital step in rational drug design. The interaction of thionine (TH) with human serum albumin (HSA) was analyzed using isothermal titration calorimetry (ITC), spectroscopic, and molecular docking technique. The emission spectral titration of HSA with TH revealed the formation of HSA-TH complex via static quenching process. The results obtained from absorption, synchronous emission, circular dichroism, and three-dimensional (3D) emission spectral studies demonstrated that TH induces changes in the microenvironment and secondary structure of HSA. Results from ITC experiments suggested that the binding of TH dye was favored by negative enthalpy and a favorable entropy contribution. Site marker competitive binding experiments revealed that the binding site of TH was located in subdomain IIA (Sudlow site I) of HSA. Molecular docking study further substantiates that TH binds to the hydrophobic cavity of subdomain IIA (Sudlow site I) of HSA. Further, we have studied the cytotoxic activity of TH and TH-HSA complex on breast cancer cell lines (MCF-7) by MTT assay and LDH assay. These studies revealed that TH-HSA complex showed the higher level of cytotoxicity in cancer cells than TH dye-treated MCF-7 cells and the significant adverse effect did not found in the normal HBL-100 cells. Fluorescence microscopy analyses of nuclear fragmentation studies validate the significant reduction of viability of TH-HSA-treated human MCF-7 breast cancer cells through activation of apoptotic-mediated pathways. PMID- 27691051 TI - Career Advancement: Meeting the Challenges Confronting the Next Generation of Endocrinologists and Endocrine Researchers. AB - CONTEXT: Challenges and opportunities face the next generation (Next-Gen) of endocrine researchers and clinicians, the lifeblood of the field of endocrinology for the future. A symposium jointly sponsored by The Endocrine Society and the Endocrine Society of Australia was convened to discuss approaches to addressing the present and future Next-Gen needs. EVIDENCE ACQUISITION: Data collection by literature review, assessment of previously completed questionnaires, commissioning of a new questionnaire, and summarization of symposium discussions were studied. EVIDENCE SYNTHESIS: Next-Gen endocrine researchers face diminishing grant funding in inflation-adjusted terms. The average age of individuals being awarded their first independent investigator funding has increased to age 45 years. For clinicians, a workforce gap exists between endocrinologists needed and those currently trained. Clinicians in practice are increasingly becoming employees of integrated hospital systems, resulting in greater time spent on nonclinical issues. Workforce data and published reviews identify challenges specifically related to early career women in endocrinology. Strategies to Address Issues: Recommendations encompassed the areas of grant support for research, mentoring, education, templates for career development, specific programs for Next-Gen members by senior colleagues as outlined in the text, networking, team science, and life/work integration. Endocrine societies focusing on Next-Gen members provide a powerful mechanism to support these critical areas. CONCLUSIONS: A concerted effort to empower, train, and support the next generation of clinical endocrinologists and endocrine researchers is necessary to ensure the viability and vibrancy of our discipline and to optimize our contributions to improving health outcomes. Collaborative engagement of endocrine societies globally will be necessary to support our next generation moving forward. PMID- 27691052 TI - mTOR Inhibitors for the Treatment of Severe Congenital Hyperinsulinism: Perspectives on Limited Therapeutic Success. AB - CONTEXT: Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycemia in neonates and infants. In medically unresponsive CHI, subtotal pancreatectomy is performed to achieve euglycemia with consequent diabetes in later life. Sirolimus, a mammalian target of rapamycin (mTOR) inhibitor, has been reported to obviate the need for pancreatectomy, but experience is limited. OBJECTIVE: We have investigated the efficacy and adverse effect profile of mTOR inhibitors in the treatment of severe CHI. DESIGN, SETTING, AND PATIENTS: This was an observational review of 10 severe CHI patients treated with mTOR inhibitors, in France and the United Kingdom, with the intention of achieving glycemic control without pancreatectomy. Safety information was recorded. MAIN OUTCOME MEASURE(S): We examined whether mTOR inhibitors achieved glycemic control, fasting tolerance, and weaning of supportive medical therapy. RESULTS: mTOR inhibition achieved euglycemia, fasting tolerance, and reduced medical therapy in only three patients (30%). Triglyceride levels were elevated in five patients (50%). One child required a blood transfusion for anemia, four had stomatitis, two had sepsis, one developed varicella zoster, and two patients developed gut dysmotility in association with exocrine pancreatic insufficiency. In silico analysis of transcriptome arrays from CHI patients revealed no significant association between mTOR signaling and disease. Pancreatic tissue from two patients who did not respond to sirolimus showed no reduction in cell proliferation, further suggesting that mTOR signaling did not down-regulate proliferation in the CHI pancreas. CONCLUSION: mTOR inhibitor treatment is associated with very limited success and must be used with caution in children with severe CHI. PMID- 27691373 TI - Psychological factors influence the gastroesophageal reflux disease (GERD) and their effect on quality of life among firefighters in South Korea. AB - OBJECTIVES: The purpose of this study was to examine psychosocial factors related to gastroesophageal reflux disease (GERD) and their effects on quality of life (QOL) in firefighters. METHODS: Data were collected from 1217 firefighters in a Korean province. We measured psychological symptoms using the scale. In order to observe the influence of the high-risk group on occupational stress, we conduct logistic multiple linear regression. The correlation between psychological factors and QOL was also analyzed and performed a hierarchical regression analysis. RESULTS: GERD was observed in 32.2% of subjects. Subjects with GERD showed higher depressive symptom, anxiety and occupational stress scores, and lower self-esteem and QOL scores relative to those observed in GERD - negative subject. GERD risk was higher for the following occupational stress subcategories: job demand, lack of reward, interpersonal conflict, and occupational climate. The stepwise regression analysis showed that depressive symptoms, occupational stress, self-esteem, and anxiety were the best predictors of QOL. CONCLUSIONS: The results suggest that psychological and medical approaches should be combined in GERD assessment.

AB - OBJECTIVE: The study examined state variation in rates of Supplemental Security Income (SSI) determinations, allowances, and receipt of benefits for ten selected child mental disabilities in 2013. METHODS: SSI administrative and U.S. Census Bureau data collected by a multidisciplinary consensus committee convened by the National Academies of Science, Engineering, and Medicine in 2015 were examined. RESULTS: Less than 1% of children in 2013 were recipients of SSI for mental disabilities. Determination rates ranged from 1,441 to 251 per 100,000 low-income children, an almost sixfold difference. Allowance rates varied from 16% to 78%, a fivefold difference. Receipt of benefits ranged from .7% to 5.3%, a sevenfold difference. CONCLUSIONS: Large unexplained discrepancies across states were found in review and receipt of SSI benefits for low-income children with mental disabilities. Inequities that cannot be explained by disability severity or financial need violate the ethos of equitable access to federally entitled services. PMID- 27691375 TI - Utilization and Cost of Health Care Services During the First Episode of Psychosis. AB - OBJECTIVE: Because of the chronicity, severity, and marked psychosocial impairment that may characterize the illness, schizophrenia is an incredibly costly disease. Recent data indicate that intervention earlier in the course of schizophrenia produces cost savings. This study compared health service utilization and associated costs for patients receiving treatment for first episode psychosis (FEP) delivered within the early-intervention (EI) model at the Prevention and Recovery Center for Early Psychosis (PARC) and for a matched sample of FEP patients receiving treatment as usual at a geographically similar mental health clinic. METHODS: This study was a retrospective assessment of 76 PARC patients and 75 patients receiving treatment as usual who were matched by age, race, sex, and diagnosis. Clinical and health service utilization data were extracted from the Midtown and Regenstrief Medical Record Systems, and differences between demographic variables, health service utilization, and cost of services were compared. RESULTS: Although individuals at PARC had higher physician and nurse visit costs, these were offset by a decrease in costs for acute service utilization. The PARC cohort did not show any difference from the comparison group in terms of total outpatient clinic services used and had fewer inpatient, psychiatric crisis, and emergency room services. Cost analyses reflected a total estimated savings of just over $6,900 per patient. CONCLUSIONS: These findings indicate not only that EI results in cost savings but that increasing medical services may be key in reducing the use of acute services, presumably because of a reduction in psychiatric and general medical pathology. PMID- 27691377 TI - Ethics of Coercive Treatment and Misuse of Psychiatry. AB - The author discusses a pragmatic approach to decisions about coercive treatment that is based on four principles from principle-based ethics: respect for autonomy, nonmaleficence, beneficence, and justice. This approach can reconcile psychiatry's perspective with the U.N. Convention on the Rights of Persons With Disabilities. Coercive treatment can be justified only when a patient's capacity to consent is substantially impaired and severe danger to health or life cannot be prevented by less intrusive means. In this case, withholding treatment can violate the principle of justice. In the case of danger to others, social exclusion and loss of freedom can be seen as harming psychosocial health, which can justify coercive treatment. Considerable efforts are required to support patients' informed decisions and avoid allowing others to make substitute decisions. Mental disorder alone without impaired capacity does not justify involuntary treatment, which can be considered a misuse of psychiatry. Involuntary detention without treatment can be justified for short periods for assessment and to offer treatment options. PMID- 27691376 TI - Collaborative Care for Perinatal Depression Among Socioeconomically Disadvantaged Women: Adverse Neonatal Birth Events and Treatment Response. AB - OBJECTIVE: The study examined the effectiveness of a perinatal collaborative care intervention in moderating the effects of adverse neonatal birth events on risks of postpartum depressive symptoms and impaired functioning among women of lower socioeconomic status with antenatal depression. METHODS: A randomized controlled trial with blinded outcome assessments was conducted in ten public health centers, comparing MOMCare (choice of brief interpersonal psychotherapy, pharmacotherapy, or both) with intensive maternity support services (MSS-Plus). Participants had probable diagnoses of major depressive disorder or dysthymia during pregnancy. Generalized estimating equations estimated differences in depression and functioning measures between groups with and without adverse birth events within the treatment arms. A total of 160 women, 43% of whom experienced at least one adverse birth event, were included in the analyses. RESULTS: For women who received MOMCare, postpartum depression scores (measured with the Symptom Checklist-20) did not differ by whether or not they experienced an adverse birth event (mean+/-SD scores of .86+/-.51 for mothers with an adverse birth event and .83+/-.56 for mothers with no event; p=.78). For women who received MSS-Plus, having an adverse birth event was associated with persisting depression in the postpartum period (mean scores of 1.20+/-.0.61 for mothers with an adverse birth event and .93+/-.52 for mothers without adverse birth event; p=.04). Similar results were seen for depression response rates and functioning. CONCLUSIONS: MOMCare mitigated the risk of postpartum depressive symptoms and impaired functioning among women of low socioeconomic status who had antenatal depression and who experienced adverse birth events. PMID- 27691378 TI - Antidepressant Medication Prescribing Practices for Treatment of Major Depressive Disorder. AB - OBJECTIVE: The purpose of this study was to describe the prescribing practices of clinicians for patients with major depressive disorder (MDD). METHODS: This population-based, descriptive study of insured patients (N=54,107) identified people who were 18 years or older, had a claim for MDD, had at least one prescription for an antidepressant medication in 2013, and had continuous insurance coverage during the study period. Prescription claims were evaluated to determine the most commonly prescribed antidepressant medication and most common dose. RESULTS: The three most commonly prescribed antidepressant medications were citalopram (N=11,995, 22.2%), sertraline (N=10,791, 19.9%), and trazodone (N=9,501, 17.6%). The most common daily doses were 20 mg citalopram (N=6,304, 52.6%), 50 mg sertraline (N=4,173, 38.7%), and 100 mg trazodone (N=3,220, 33.9%). CONCLUSIONS: This is the first report of its kind that provides drug- and dosage level details to demonstrate that antidepressant prescribing in clinical practice is largely within recommended guidelines.

PMID- 27691380 TI - The Humble Leader: Association of Discrepancies in Leader and Follower Ratings of Implementation Leadership With Organizational Climate in Mental Health. AB - OBJECTIVES: Discrepancies, or perceptual distance, between leaders' self-ratings and followers' ratings of the leader are common but usually go unrecognized. Research on discrepancies is limited, but there is evidence that discrepancies are associated with organizational context. This study examined the association of leader-follower discrepancies in Implementation Leadership Scale (ILS) ratings of mental health clinic leaders and the association of those discrepancies with organizational climate for involvement and performance feedback. Both involvement and performance feedback are important for evidence-based practice (EBP) implementation in mental health. METHODS: A total of 593 individuals-supervisors (leaders, N=80) and clinical service providers (followers, N=513)-completed surveys that included ratings of implementation leadership and organizational climate. Polynomial regression and response surface analyses were conducted to examine the associations of discrepancies in leader-follower ILS ratings with organizational involvement climate and performance feedback climate, aspects of climate likely to support EBP implementation. RESULTS: Both involvement climate and performance feedback climate were highest where leaders rated themselves low on the ILS and their followers rated those leaders high on the ILS ("humble leaders"). CONCLUSIONS: Teams with "humble leaders" showed more positive organizational climate for involvement and for performance feedback, contextual factors important during EBP implementation and sustainment. Discrepancy in leader and follower ratings of implementation leadership should be a consideration in understanding and improving leadership and organizational climate for mental health services and for EBP implementation and sustainment in mental health and other allied health settings. PMID- 27691381 TI - Assessing Telemedicine Utilization by Using Medicaid Claims Data. AB - OBJECTIVE: This study characterized telemedicine utilization among Medicaid enrollees by patients' demographic characteristics, geographic location, enrollment type, eligibility category, and clinical conditions. METHODS: This study used 2008-2009 Medicaid claims data from 28 states and the District of Columbia to characterize telemedicine claims (indicated by GT for professional fee claims or Q3014 for facility fees) on the basis of patients' demographic characteristics, geographic location, enrollment type, eligibility category, and clinical condition as indicated by ICD-9 codes. States lacking Medicaid telemedicine reimbursement policies were excluded. Chi-square tests were used to compare telemedicine utilization rates and one-way analysis of variance was used to estimate mean differences in number of telemedicine encounters among subgroups. RESULTS: A total of 45,233,602 Medicaid enrollees from the 22 states with telemedicine reimbursement policies were included in the study, and .1% were telemedicine users. Individuals ages 45 to 64 (16.4%), whites (11.3%), males (8.5%), rural residents (26.0%), those with managed care plans (7.9%), and those categorized as aged, blind, and disabled (28.1%) were more likely to receive telemedicine (p<.001). Nearly 95% of telemedicine claims were associated with a behavioral health diagnosis, of which over 50% were for bipolar disorder and attention-deficit disorder or attention-deficit hyperactivity disorder (29.3% and 23.4%, respectively). State-level variation was high, ranging from .0 to 59.91 claims per 10,000 enrollees (Arkansas and Arizona, respectively). CONCLUSIONS: Despite the touted potential for telemedicine to improve health care access, actual utilization of telemedicine in Medicaid programs was low. It was predominantly used to treat behavioral health diagnoses. Reimbursement alone is insufficient to support broad utilization for Medicaid enrollees. PMID- 27691387 TI - News & Notes.

PMID- 27691382 TI - Qualitative Analysis of Resources and Barriers Related to Treatment of Borderline Personality Disorder in the United States. AB - OBJECTIVE: Resources and treatment for individuals with borderline personality disorder (BPD) are limited and often difficult to obtain. This article aimed to identify key resources for and barriers to obtaining supportive and treatment services for BPD from the perspective of individuals seeking information or services related to BPD ("BPD care seekers"). METHODS: Data came from transcripts of resource requests to the Borderline Personality Disorder Resource Center from January 2008 to December 2015 (N=6,253). Basic statistics, including the type of service requested, demographic information for the BPD care seeker, and national distribution of requests, were generated for all eligible transcripts. Qualitative analysis of a random subset of 500 transcripts was used to identify themes, challenges, and common experiences reported by BPD care seekers. RESULTS: The greatest number of requests for primary services or resources among the random subset of transcripts was for outpatient services (51%), informational materials (13%), and day programs (9%). Family services, crisis intervention, and mental health literacy were identified as areas where available resources did not meet current demand and that could be improved or expanded. Factors identified as potential barriers to finding and obtaining appropriate treatment for BPD included stigmatization and marginalization within mental health care systems, financial concerns, and comorbidity with psychiatric or medical disorders. CONCLUSIONS: BPD care seekers face numerous barriers to obtaining appropriate care. Expanded services and resources to connect individuals with treatment are needed to meet the current demands and preferences of those seeking care.

AB - The main objective of this work was to develop polyelectrolyte complex (PEC) nanoparticles based on poly (malic acid), chitosan (PMLA/CS) as pH-dependent delivery systems. The results indicated that the PMLA/CS Nps were successfully prepared. The prepared PMLA/CS Nps showed spherical morphology with a mean diameter of 212.81 nm and negative surface charge of -24.60 mV, and revealing significant pH-sensitive properties as the mass ratio of PMLA to CS was 5:5. The prepared PMLA/CS Nps were characterized by FT-IR, TEM and DLS. The prepared PMLA/CS Nps remained stable over a temperature range of 4-53 degrees C. Doxorubicin (Dox) as a model drug was loaded on the nanoparticles through the physical adsorption method. The high drug loading efficiency (16.9%) and the sustained release patterns in acidic media were observed, and the release accelerated in alkaline solutions. MTT based cytotoxic analysis also depicted the non-toxic nature of PMLA/CS Nps, while Dox-PMLA/CS Nps showed dose-dependent cytotoxicity towards MDA-MB-231 cells. Hence, the nanoparticles could be potentially applied as pH sensitive drug vehicles for controlled release. PMID- 27691399 TI - Affinity enhancement of nanobody binding to EGFR: in silico site-directed mutagenesis and molecular dynamics simulation approaches. AB - Epidermal growth factor receptor (EGFR), a transmembrane glycoprotein, is overexpressed in many cancers such as head-neck, breast, prostate, and skin cancers for this reason it is a good target in cancer therapy and diagnosis. In nanobody-based cancer diagnosis and treatment, nanobodies with high affinity toward receptor (e.g. EGFR) results in effective treatment or diagnosis of cancer. In this regard, the main aim of this study is to develop a method based on molecular dynamic (MD) simulations for designing of 7D12 based nanobody with high affinity compared with wild-type nanobody. By surveying electrostatic and desolvation interactions between different residues of 7D12 and EGFR, the critical residues of 7D12 that play the main role in the binding of 7D12 to EGFR were elucidated and based on these residues, five logical variants were designed. Following the 50 ns MD simulations, pull and umbrella sampling simulation were performed for 7D12 and all its variants in complex with EGFR. Binding free energy of 7D12 (and all its variants) with EGFR was obtained by weighted histogram analysis method. According to binding free energy results, GLY101 to GLU mutation showed the highest binding affinity but this variant is unstable after 50 ns MD simulations. ALA100 to GLU mutation shows suitable binding enhancement with acceptable structural stability. Suitable position and orientation of GLU in residue 100 of 7D12 against related amino acids of EGFR formed some extra hydrogen and electrostatic interactions which resulted in binding enhancement. PMID- 27691453 TI - Study of positive and negative plasma catalytic oxidation of ethylene. AB - The effect of introducing a photocatalytically active coating inside a plasma unit is investigated. This technique combines the advantages of high product selectivity from catalysis and the fast start-up from plasma technology. In this study, a preselected TiO2 coating is applied on the collector electrode of a DC corona discharge unit as non-thermal plasma reactor, in order to study the oxidation of ethylene. For both positive and negative polarities an enhanced mineralization is observed while the formation of by-products drastically decreases. The plasma catalytic unit gave the best results when using negative polarity at a voltage of 15 kV. This shows the potential of plasma catalysis as indoor air purification technology.

AB - The purpose of this study was to compare force- and power-time curve variables during jumping between Division I strength-matched male and female basketball athletes. Males (n = 8) and females (n = 8) were strength matched by testing a one-repetition maximum (1RM) back squat. 1RM back squat values were normalised to body mass in order to demonstrate that strength differences were a function of body mass alone. Subjects performed three countermovement jumps (CMJ) at maximal effort. Absolute and relative force- and power-time curve variables from the CMJs were analysed between males and females. Average force- and power-time curves were generated for all subjects. Jump height was significantly greater (p <= .05) in males than females. Absolute force was higher in males during the concentric phase, but not significantly different (p >= .05) when normalised to body mass. Significance was found in absolute concentric impulse between sexes, but not when analysed relative to body mass. Rate of force development, rate of power development, relative peak force, and work were not significantly different between sexes. Males had significantly greater impulse during the eccentric phase as well as peak power (PP) during the concentric phase of the CMJ than did females in both absolute and relative terms. It is concluded that sex differences are not a determining factor in measured force during a CMJ when normalised to body mass between strength-matched subjects. However, eccentric phase impulse and concentric phase PP appear to be influenced by sex differences independent of matching strength levels. PMID- 27691601 TI - Methoxy poly (ethylene glycol)-b-poly (delta-valerolactone) copolymeric micelles for improved skin delivery of ketoconazole. AB - Ketoconazole is a broad spectrum imidazole antifungal drug. For the treatment of superficial fungal infections with ketoconazole, it needs to be permeated to deep skin layers. In order to develop topical formulation of ketoconazole for improving its skin deposition and water-solubility, ketoconazole-loaded methoxy poly (ethylene glycol)-b-poly (delta-valerolactone) micelles were developed through thin-film hydration method. Particle size, drug loading capacity, infrared spectrum and X-ray diffraction of drug-loaded micelles were characterized. The optimal drug formulation was selected for skin delivery and deposition investigation performed by use of mice skin, and its in vitro release and antifungal activity were also investigated. Penetration and distribution in the skin were also visualized using fluorescein-loaded micelles and fluorescence microscopy. The drug-loaded micelles were obtained with encapsulation efficiency of 86.39% and particle diameter of about 12 nm. The micelles made ketoconazole aqueous solubility increase to 86-fold higher than crude one. Ketoconazole-loaded micelles showed no skin permeation of ketoconazole, obviously enhance skin deposition and demonstrated similar antifungal activity as compared with marketed ketoconazole cream. Fluorescein-loaded micelles displayed higher skin deposition than fluorescein water solution. These results demonstrate that the MPEG-PVL micelle is a potential delivery system for ketoconazole in the field of skin delivery.

The many factors affecting adsorption were successfully investigated. The maximum capacity of Fe(III) ions was 320 (mg/g) for PVA@P(90AMPS-co-10NIPAm) (wt.: wt%). The equilibrium data matching well with the Langmuir model and the pseudo-second-order form described the adsorption process better than the pseudo-first-order model. Findings of the present study highlight using a simple synthesis of PVA@P(AMPS-co-NIPAm) nanogels as superior and recyclable nanoadsorbents.

AB - In the present study, quick-lime-based thermal-alkaline sludge disintegration (SD) under low temperature was combined with cryptic growth to investigate the excess sludge reduction efficiency in the sequencing batch reactor (SBR). The optimized condition of SD was as follows: T = 80C, pH = 11, t = 180 min, and the SD rate was about 42.1%. With 65.6% of excess sludge disintegrated and returned to the SBR, the system achieved sludge reduction rate of about 40.1%. The lysis cryptic growth still obtained satisfactory sludge reduction efficiency despite the comparative low SD rate, which suggested that disintegration rate might not be the decisive factor for cryptic-growth-based sludge reduction. Lysis-cryptic growth did not impact the effluent quality, yet the phosphorus removal performance was enhanced, with effluent total phosphorus concentration decreased by 0.3 mg/L (33%). Crystal compounds of calcium phosphate precipitate were detected in the system by Fourier transform infrared spectroscopy and X-ray diffraction, which indicated the phosphorus removal potential of SD using lime. Moreover, endogenous dehydrogenase activity of activated sludge in the lysis cryptic system was enhanced, which was beneficial for sludge reduction. SD and cryptic growth in the present study demonstrates an economical and effective approach for sludge reduction. PMID- 27691719 TI - The (oxalato)aluminate complex as an antimicrobial substance protecting the "shiro" of Tricholoma matsutake from soil micro-organisms. AB - Tricholoma matsutake, a basidiomycete, forms ectomycorrhizas with Pinus densiflora as the host tree. Its fruiting body, "matsutake" in Japanese, is an edible and highly prized mushroom, and it grows in a circle called a fairy ring. Beneath the fairy ring of T. matsutake, a whitish mycelium-soil aggregated zone, called "shiro" in Japanese, develops. The front of the shiro, an active mycorrhizal zone, functions to gather nutrients from the soil and roots to nourish the fairy ring. Bacteria and sporulating fungi decrease from the shiro front, whereas they increase inside and outside the shiro front. Ohara demonstrated that the shiro front exhibited antimicrobial activity, but the antimicrobial substance has remained unidentified for 50 years. We have identified the antimicrobial substance as the (oxalato)aluminate complex, known as a reaction product of oxalic acid and aluminum phosphate to release soluble phosphorus. The complex protects the shiro from micro-organisms, and contributes to its development. PMID- 27691720 TI - Effect of seven Indian plant extracts on Fenton reaction-mediated damage to DNA constituents. AB - The influences of substoichiometric amounts of seven plant extracts in the Fenton reaction-mediated damage to deoxynucleosides, deoxynucleoside monophosphates, deoxynucleoside triphosphates, and supercoiled plasmid DNA were studied to rationalize anticancer properties reported in some of these extracts. Extracts from Acacia catechu, Emblica officinalis, Spondias dulcis, Terminalia belerica, Terminalia chebula, as well as gallic acid, epicatechin, chebulagic acid and chebulinic acid enhance the extent of damage in Fenton reactions with all monomeric substrates but protect supercoiled plasmid DNA, compared to standard Fenton reactions. The damage to pyrimidine nucleosides/nucleotides is enhanced by these extracts and compounds to a greater extent than for purine ones in a concentration dependent manner. Dolichos biflorus and Hemidesmus indicus extracts generally do not show this enhancement for the monomeric substrates though they protect plasmid DNA. Compared to standard Fenton reactions for deoxynucleosides with ethanol, the presence of these five plant extracts render ethanol scavenging less effective as the radical is generated in the vicinity of the target. Since substoichiometric amounts of these extracts and the four compounds produce this effect, a catalytic mechanism involving the presence of a ternary complex of the nucleoside/nucleotide substrate, a plant compound and the hydroxyl radical is proposed. Such a mechanism cannot operate for plasmid DNA as the planar rings in the extract compounds cannot stack with the duplex DNA bases. These plant extracts, by enhancing Fenton reaction-mediated damage to deoxynucleoside triphosphates, slow down DNA replication in rapidly dividing cancer cells, thus contributing to their anticancer properties. PMID- 27691721 TI - Sensitivity, reliability and the effects of diurnal variation on a test battery of field usable upper limb fatigue measures. AB - Fatigue has been linked to deficits in production quality and productivity and, if of long duration, work-related musculoskeletal disorders. It may thus be a useful risk indicator and design and evaluation tool. However, there is limited information on the test-retest reliability, the sensitivity and the effects of diurnal fluctuation on field usable fatigue measures. This study reports on an evaluation of 11 measurement tools and their 14 parameters. Eight measures were found to have test-retest ICC values greater than 0.8. Four measures were particularly responsive during an intermittent fatiguing condition. However, two responsive measures demonstrated rhythmic behaviour, with significant time effects from 08:00 to mid-afternoon and early evening. Action tremor, muscle mechanomyography and perceived fatigue were found to be most reliable and most responsive; but additional analytical considerations might be required when interpreting daylong responses of MMG and action tremor. Practitioner Summary: This paper presents findings from test-retest and daylong reliability and responsiveness evaluations of 11 fatigue measures. This paper suggests that action tremor, muscle mechanomyography and perceived fatigue were most reliable and most responsive. However, mechanomyography and action tremor may be susceptible to diurnal changes. PMID- 27691776 TI - Current Status of Home Medical Care Waste Collection by Nurses in Japan. AB - : A questionnaire survey was conducted to determine the current status of home medical care (HMC) waste collection by nurses for individual items and whether the collection rate differs with city size. The questionnaire was mailed to 1,022 nursing offices, of which 645 offices provided valid responses. Offices were classified into three groups according to the local population size. Responses indicated that used syringes and needles, except for pen-type self-injection needles, were collected by >50% of HMC nurses. On the other hand, enteral nutrients, nutritional adjustment diet vessels, feeding tubes, portable injectors, ventilator masks, endotracheal suction catheters, tracheal cannulas, continuous ambulatory peritoneal dialysis (CAPD) bags, and urinary catheters and bags had a low collection rate in comparison with syringes or needles. The collection percentage of used syringes, needles, and infusion needles (p < 0.05) and that for infusion bags, tubes, and catheters (p < 0.001) differed among the three population groups. Although municipalities are responsible for collect all HMC waste, sharp or infectious items should be collected by HMC doctors or nurses. On the contrary, nonhazardous HMC waste should be collected by municipalities. IMPLICATIONS: This paper illustrates the status of waste collection of individual home medical care (HMC) items by HMC nurses. Infectious waste, such as needles and syringes, is collected by nurses. The collection rate of infectious waste by nurses in large cities was low compared with that in small cities. Although municipalities are responsible for collecting all HMC waste, sharp or infectious items should be collected by HMC doctors or nurses, whereas nonhazardous HMC waste should be collected by the municipalities.

AB - This study examined the experiences that lesbian, gay, bisexual, transgender, queer, questioning, and two-spirit (LGBTQ2S) homeless youth have in shelters and the disjunctures that occur for this population in Toronto's shelter system. The attitudes and behaviors of shelter workers and management toward LGBTQ2S youth were also explored. A critical action research approach, informed by critical ethnography and institutional ethnography was employed. Thirty-three people participated in this study in the Greater Toronto Area. The study triangulated data from interviews, focus groups, observations, and document analysis. The systemic enactment of homophobia, transphobia, and hegemonic masculinity are often normalized in shelters and create significant barriers to safe, accessible, and supportive services for LGBTQ2S youth. Excessive bureaucratic regulation and the lack of necessary bureaucratic regulation in highly significant areas play a key role in creating the disjunctures that occur for LGBTQ2S youth in shelters. PMID- 27691780 TI - Torsion of a mesenchymal hamartoma of the liver in a 1-year-old boy. AB - We report a case of a one-year-old boy who was referred to our clinic suspected of having acute abdomen. On physical examination, the abdomen was soft, diffusely tender with weak peristalsis. Ultrasonography and MRI of the right hemiabdomen demonstrated a well-defined, solid, expansive formation with slightly lobulated contours and an interspersed inhomogeneous structure with overall dimensions of 59 * 45 * 50 mm. After midline laparotomy was performed, a cystic tumor was found, twisted around a pedicle which was arising from the falciform ligament and it measured 5-6 cm in diameter. The tumor appeared to be necrotic. The mass was ligated and extirpated on the pedicle and sent for histopathological analysis. After the surgery, the boy was hemodynamically stable, without respiratory complications and all laboratory findings were within normal limits. Histopathological analysis showed that the tumor was composed of mesenchymal stroma with sparse glimpses of hepatocytes and bile ducts with partly cystic changes lined by orderly epithelium. Given the clinical data, histology and immunohistochemistry analysis (alpha-fetoprotein, CK8/18, hepatocyte, desmin and CD31) a diagnosis of a twisted mesenchymal hamartoma of the liver was made. PMID- 27691783 TI - Exploring stereochemical specificity of phosphotriesterase by MM-PBSA and MM-GBSA calculation and steered molecular dynamics simulation. AB - Wild-type phosphotriesterase (PTE) prefers the SP-enantiomers over the corresponding RP-enantiomers by factors ranging from 10 to 90. To satisfy the binding modes of the PTE of SP- and RP-enantiomers, all-atom molecular dynamics simulations were carried out on two paraoxon SP and RP derivatives, namely, Sp-1 and Rp-1. Molecular mechanics Poisson-Boltzmann surface area and molecular mechanics generalized Born surface area (MM-PBSA and MM-GBSA) calculations indicated that His230 in Sp-1-PTE had a closer interaction with the substrate than that in Rp-1-PTE and that such interaction increased the catalytic efficiency of PTE for Sp-1. The steered molecular dynamics simulation indicated that, compared with Sp-1, Rp-1 in the unbinding (binding) may hinder some residue displacement, thus requiring more effort to escape the binding pocket of PTE. In addition, Trp131, Phe306, and Tyr309 are deemed important residues for the Sp-1 unbinding pathway via PTE, whereas Tyr309 alone is considered an important residue for the Rp-1 unbinding pathway. These results demonstrate the possibility of dramatically altering the stereoselectivity and overall reactivity of the native enzyme toward chiral substrates by modifying specific residues located within the active site of PTE. PMID- 27691840 TI - Is Gaydar Affected by Attitudes Toward Homosexuality? Confidence, Labeling Bias, and Accuracy. AB - Previous research has largely ignored the relationship between sexual orientation judgement accuracy, confidence, and attitudes toward homosexuality. In an online study, participants (N = 269) judged the sexual orientation of homosexual and heterosexual targets presented via a series of facial photographs. Participants also indicated their confidence in each judgment and completed the Modern Homonegativity Scale (Morrison & Morrison, 2002). We found that (1) homosexual men and heterosexual women were more accurate when judging photographs of women as opposed to photographs of men, and (2) in heterosexual men, negative attitudes toward homosexual men predicted confidence and bias when rating men's photographs. Findings indicate that homosexual men and heterosexual women are similar in terms of accuracy in judging women's sexuality. Further, especially in men, homophobia is associated with cognitive biases in labeling other men but does not have a relationship with increased accuracy. PMID- 27691784 TI - Personal value preferences, group identifications, and cultural practices of Palestinian Israelis working in close contact with Jewish Israelis. AB - The present study investigates the connection between personal value preferences, group identifications, and cultural practices among Palestinian Israelis working in close contact with the Jewish population in Israel. One hundred twenty-two Palestinian Israelis participated in the study. The participants were employed in different professional positions in the Tel Aviv Metropolitan area and were recruited to the study using the snowball technique. A stronger national identification was associated with a higher preference for the security and conformity values, and a lower preference for the humility values. A stronger ethnic identification was associated with a lower preference for the security, power, and stimulation values. Group identifications mediated the connection between personal value preferences and cultural practices. A longer time working in close contact with the majority group and less frequent visits home were associated with a greater adherence to the majority group's cultural practices but not with adherence to the ethnic group's practices and not with the group identifications. PMID- 27691841 TI - Contribution of 2-methyl-3-furanthiol to the cooked meat-like aroma of fermented soy sauce. AB - The cooked meat-like aroma compound, 2-methyl-3-furanthiol (2M3F), was detected in fermented soy sauce (FSS) by GC-olfactometry and GC-MS. 2M3F was present in FSS at a concentration considerably greater than the perception threshold, and the 2M3F concentration increased with heating temperature. Sensory analysis indicated that with the addition of only 0.2 MUg/L of 2M3F to the soy sauce sample, the cooked meat-like aroma is significantly stronger than that of sample without the addition of 2M3F. Hence, 2M3F contributes to the cooked meat-like aroma of FSS, which constitutes the key aroma component of FSS. In addition, 2M3F was generated from the addition of ribose and cysteine in FSS by heating at 120 degrees C, but it was not detected in a phosphate buffer under the same condition. Furthermore, 2M3F was not detected in acid-hydrolyzed vegetable protein-mixed soy sauce (ASS) and heated ASS. These results indicated that fermentation by micro-organisms facilitates the generation of 2M3F in FSS. PMID- 27691842 TI - Design of novel lead molecules against RhoG protein as cancer target - a computational study. AB - Cancer is a class of diseases characterized by uncontrolled cell growth. Every year more than 2 million people are affected by the disease. Rho family proteins are actively involved in cytoskeleton regulation. Over-expression of Rho family proteins show oncogenic activity and promote cancer progression. In the present work RhoG protein is considered as novel target of cancer. It is a member of Rho family and Rac subfamily protein, which plays pivotal role in regulation of microtubule formation, cell migration and contributes in cancer progression. In order to understand the binding interaction between RhoG protein and the DH domain of Ephexin-4 protein, the 3D structure of RhoG was evaluated and Molecular Dynamic Simulations was performed to stabilize the structure. The 3D structure of RhoG protein was validated and active site identified using standard computational protocols. Protein-protein docking of RhoG with Ephexin-4 was done to understand binding interactions and the active site structure. Virtual screening was carried out with ligand databases against the active site of RhoG protein. The efficiency of virtual screening is analysed with enrichment factor and area under curve values. The binding free energy of docked complexes was calculated using prime MM-GBSA module. The SASA, FOSA, FISA, PISA and PSA values of ligands were carried out. New ligands with high docking score, glide energy and acceptable ADME properties were prioritized as potential inhibitors of RhoG protein. PMID- 27691903 TI - Association between possible sleep bruxism and sleep characteristics in children. AB - AIMS: To evaluate the relationship between possible sleep bruxism and sleep characteristics in children. METHODOLOGY: A cross-sectional study was conducted through data collection of a pre-tested questionnaire answered by 111 parents on behalf of their children in the waiting room during their appointment at the Pediatric Dentistry Clinic of a public Brazilian university. The diagnosis of possible sleep bruxism was based on the international classification of sleep disorders (ICSD) criteria. The Chi-square test and logistic multinomial regression test were used in the statistical analysis. RESULTS: The final model of logistic multinomial regression demonstrated that children with muscle pain in the mouth region (OR = 19.70 95% IC = 1.82-212.69), snoring (OR = 8.25 95% IC = 2, 56-26, 54), and those with parents with possible sleep bruxism have more of a probability of sleep bruxism. CONCLUSION: Potential sleep bruxism tends to be hereditary. Muscle pain, snoring, and mouth breathing were important signals associated with possible sleep bruxism among children. PMID- 27691904 TI - Pharmacokinetics and estimated bioavailability of grapiprant, a novel selective prostaglandin E2 receptor antagonist, after oral administration in fasted and fed dogs. AB - AIMS: To assess the effect of food intake on the pharmacokinetics of grapiprant administered orally at 2 mg/kg, and to estimate its oral bioavailability in dogs. METHODS: Eight healthy female Labrador Retriever dogs, aged 4-10 years were used. In the initial trial two dogs were administered a 0.5 mg/kg I/V bolus of grapiprant dissolved in ethanol. In the second trial, six dogs were assigned to two treatment groups, using a randomised cross-over design, and received 2 mg/kg of grapiprant orally, as pure powder, after fasting for 12 hours or after being fed. Blood samples were collected at preassigned times up to 36 hours after administration, and concentrations of grapiprant in plasma determined using validated high performance liquid chromatography. RESULTS: After I/V administration in the two dogs the terminal half life was 5.30 and 6.06 hours, clearance was 444 and 476 mL/hours/kg, and volume of distribution was 3,642 and 3,883 mL/kg. Compared with fasted dogs, oral administration in fed dogs resulted in reduced median peak concentrations in plasma (1,598 vs. 614 ng/mL) and delayed median time of peak concentration (1.0 vs. 3.0 hours). The estimated bioavailability in fasted and fed dogs was 111.9 and 59.1%, respectively. Concentrations of grapiprant in plasma following oral administration, in either fed or fasted dogs, remained higher than 164 ng/mL for up to 6 hours. This concentration has been estimated to be the minimal effective concentration required to control pain in dogs. CONCLUSION AND RELEVANCE: Oral administration of 2 mg/kg grapiprant in fed and fasted dogs resulted in different pharmacokinetics of the drug, but did not influence the length of time when concentrations in plasma exceeded theoretical effective concentrations. Further studies are necessary to verify these findings using pharmacokinetic pharmacodynamic studies and in clinical subjects. PMID- 27691905 TI - Genome shuffling of Lactobacillus plantarum C88 improves adhesion. AB - Genome shuffling is an important method for rapid improvement in microbial strains for desired phenotypes. In this study, ultraviolet irradiation and nitrosoguanidine were used as mutagens to enhance the adhesion of the wild-type Lactobacillus plantarum C88. Four strains with better property were screened after mutagenesis to develop a library of parent strains for three rounds of genome shuffling. Fusants F3-1, F3-2, F3-3, and F3-4 were screened as the improved strains. The in vivo and in vitro tests results indicated that the population after three rounds of genome shuffling exhibited improved adhesive property. Random Amplified Polymorphic DNA results showed significant differences between the parent strain and recombinant strains at DNA level. These results suggest that the adhesive property of L. plantarum C88 can be significantly improved by genome shuffling. Improvement in the adhesive property of bacterial cells by genome shuffling enhances the colonization of probiotic strains which further benefits to exist probiotic function. PMID- 27691906 TI - Skeletal deformities associated with nutritional congenital rickets in newborn lambs. AB - CASE HISTORY: A group of 545 pregnant rising 2-year-old Coopdale ewes on a Southland sheep farm were grazed over winter on a fodder beet (Beta vulgaris) crop. Subsequently, 45 out of approximately 750 lambs were born with a variety of skeletal deformities, including shortened limbs, varus and valgus angular limb deformities, palmar grade stance and cranial bowing of the carpus. Analysis of the crop showed the fodder beet contained a low percentage of phosphorus. In addition, 60 out of 460 rising 2-year-old ewes that had been grazed on the fodder beet crop as 1-year-olds had incisor abnormalities and malocclusion. PATHOLOGICAL FINDINGS: Two affected lambs (1-day-old and 3-days-old) with representative clinical signs examined postmortem were found to have markedly enlarged costochondral junctions, and noticeably enlarged long bone metaphyses. In addition, one lamb had a dense band of metaphyseal sclerosis beneath the physes of all long bones examined. Histopathological findings included small islands and columns of chondrocytes and eosinophilic cartilage matrix present in the metaphysis. Metaphyseal trabeculae were disorganised and often lined by accumulations of pale pink osteoid; similar pale pink osteoid was also present in the cortices. Unerupted molar teeth in the affected lambs lacked a layer of enamel, and the dentine was irregular with globular basophilia. DIAGNOSIS: The gross and histopathological lesions were consistent with a diagnosis of rickets. CLINICAL RELEVANCE: Nutritional congenital rickets has not been previously diagnosed in sheep, but is a recognised disease of human infants with vitamin D deficient mothers. The rickets in affected lambs was most likely associated with phosphorus deficiency as a result of the pregnant ewes grazing fodder beet during gestation. While vitamin D deficiency was not definitively ruled out in these cases, practitioners are alerted to the possible effects of feeding phosphorus deficient fodder beet to ewes for long periods during gestation and to 1-year-old sheep during important growth periods. PMID- 27691907 TI - Investigation of fetal loss in ewe lambs in relation to liveweight changes and progesterone concentrations in early to mid gestation. AB - AIMS: To investigate associations between changes in liveweight and fetal loss in ewe lambs and to determine whether fetal loss was associated with concentrations of progesterone in early and mid-gestation. METHODS: Ewe lambs on two commercial sheep farms (Flock A; n=504 and Flock B; n=460) in the southern North Island of New Zealand were weighed, and body condition score was assessed, prior to breeding and throughout pregnancy. Pregnancy diagnosis was undertaken approximately 56 (PD1), 80 (PD2) and 110 (PD3) days after the start of breeding and fetal loss determined. Blood samples were collected from a cohort of 407 ewe lambs between 45-54 and 73-84 days of gestation. Those that subsequently were diagnosed with fetal loss (n=16) were matched with ewe lambs that maintained pregnancy (n=16), and concentrations of progesterone were measured in the plasma samples from these animals. RESULTS: Fetal loss was diagnosed in 55/472 (11.7%) pregnant ewes from Flock A and 14/378 (3.7%) from Flock B. In both flocks the change in conceptus-free liveweight (CFLW) between PD1 and PD2 differed between ewe lambs with and without fetal loss; in Flock A the mean change was -59.9 (95% CI=-80.1 to -39.7) g/day vs. -3.43 (95% CI=-9.8 to 3.0) g/day (p<0.001), and in Flock B the change was -38.5 (95% CI=-78.9 to 1.94) g/day vs. 79.5 (95% CI=72.6 86.4) g/day (p<0.001). Similarly in Flock A the mean increase in CFLW between PD2 and PD3 was lower in ewe lambs with fetal loss than in those that maintained pregnancy (25.8 (95% CI=-13.8 to 65.4) g/day vs. 181.9 (95% CI=175.1-188.7) g/day) (p<0.001). There was no difference (p>0.05) in early and mid-gestation mean concentrations of progesterone in plasma between ewe lambs that had fetal loss compared with those that maintained pregnancy. CONCLUSIONS: Ewe lambs with fetal loss had a marked reduction in CFLW in the 24-30 days leading up to the identification of the fetal loss compared with those that maintained pregnancy. Early and mid-gestation concentrations of progesterone in plasma were similar between ewe lambs who went on to have fetal loss and those that maintained pregnancy.

PMID- 27691910 TI - Primary care education: medical student and young doctors' perspective from Brazil, India and Portugal. AB - This opinion paper is a collaborative effort describing recent developments in primary care education in three different countries; representing diverse socioeconomic and political systems. The authors describe their respective perspectives from the point of student (Brazil), trainee (Portugal) and young doctor (India). The section on Brazil focuses on the response of the medical education system to the developments before and after political reforms, leading to creation of the Unified Health System. The Indian experience focuses on the challenges faced by recently qualified doctors and ongoing debates about the medical education system in a highly populated but rapidly growing economy. The Portuguese section presents an evolving primary care education system for family doctors and describes the detail of the training programme. Education in primary care is an ever-evolving process that needs to be adequate for each country's health care system. Reading and learning from other experiences may highlight education strategies that may be adopted by peers from other countries. Medical students, doctors in training and recently qualified doctors are the key stakeholders in this process.

AB - AmfS, a class III lantipeptide serves as a morphogen in Streptomyces griseus. Here, we constructed a high production system of AmfS in S. griseus. We isolated S. griseus Grd1 strain defective in glucose repression of aerial mycelium formation and found it suitable for the overproduction of AmfS. Two expression vectors carrying the strong and constitutive ermE2 promoter were constructed using a multicopy number plasmid, pIJ702. The use of the Grd1 strain combined with the expression vectors enabled high production of AmfS by S. griseus into its culture broth. The expression system was also effective for the generation of abundant AmfS derived from Streptomyces avermitilis. In addition, site-directed mutagenesis revealed the amino acid residues essential for the morphogen activity of AmfS. These results indicate that the constructed system enables efficient production of class III lantipeptides by Streptomyces. PMID- 27691922 TI - Using peer-mediated instruction to support communication involving a student with autism during mathematics activities: A case study. AB - This study employed an A-B singled subject design to explore the extent to which a peer-mediated intervention supported a first-grade student with autism's usage both in purpose and frequency of a speech-generating device (SGD) during mathematics activities. The intervention involved teaching a peer without a disability to encourage the student with autism to use the SGD during partnered mathematics activities. Our analysis involved visual and descriptive examination of trends and patterns over time, and comparison of means between and within phases. We found during the course of this study that (1) the student with autism's level of overall communication, which included the relevancy of these communicative behaviors, increased; (2) the student with autism's level of spontaneous communication acts increased; and (3) the peer became more independent with supporting the student with autism's communication. Implications for future research and practice are provided. PMID- 27691923 TI - Effects of GABA on the expression of type I collagen gene in normal human dermal fibroblasts. AB - We examined the effects of GABA on type I collagen gene expression in normal human dermal fibroblasts. Real-time PCR analysis indicated GABA increased the level of type I collagen transcripts, and suppressed the expression of matrix metalloproteinase-1, which is a collagen-degrading enzyme. These results suggest GABA improves the skin elasticity by regulating type I collagen expression. PMID- 27691924 TI - Temperature measurement and control system for transtibial prostheses: Functional evaluation. AB - The accumulation of heat inside the prosthetic socket increases skin temperature and fosters perspiration, which consequently leads to high tissue stress, friction blister, discomfort, unpleasant odor, and decreased prosthesis suspension and use. In the present study, the prototype of a temperature measurement and control (TM&C) system was designed, fabricated, and functionally evaluated in a phantom model of the transtibial prosthetic socket. The TM&C system was comprised of 12 thermistors divided equally into two groups that arranged internal and external to a prosthetic silicone liner. Its control system was programmed to select the required heating or cooling function of a thermal pump to provide thermal equilibrium based on the amount of temperature difference from a defined set temperature, or the amount of difference between the mean temperature recorded by inside and outside thermistors. A thin layer of aluminum was used for thermal conduction between the thermal pump and different sites around the silicone liner. The results showed functionality of the TM&C system for thermoregulation inside the prosthetic socket. However, enhancing the structure of this TM&C system, increasing its thermal power, and decreasing its weight and cost are main priorities before further development.

AB - In neurofibromatosis type 2 (NF2) bilateral vestibular schwannomas (VS) or their treatment usually results in bilateral hearing loss. Cochlear implantation (CI) was traditionally not used in these patients due to concern that retrocochlear disease would render the implant ineffective. This paper describes the auditory outcomes of CI in 13 patients with NF2 and includes patients with untreated VS and patients undergoing VS removal with cochlear nerve preservation. The non-user rate was 7.7%. Of the active users, median CUNY score was 98%, median BKB score in quiet was 90% and median BKB score in noise was 68%. CI is a viable option in selected patients with NF2. PMID- 27691935 TI - COMBINATION THERAPY WITH FLUOXETINE AND ALPRAZOLAM TO CONTROL ANXIETY IN A HAND REARED SNOW LEOPARD (UNCIA UNCIA). AB - A captive hand-reared adult male snow leopard ( Uncia uncia ) was treated for anxiety associated with taunting from visitors, the presence of large crowds, and introduction to a female for breeding. Behaviors included shaking, chewing on tail, panting, panicking, and bouncing off the viewing glass, pacing, and avoidance of the female. Combination therapy of oral fluoxetine and alprazolam were administered initially to minimize anxious behaviors while the fluoxetine achieved therapeutic levels. The alprazolam was tapered completely and was only used episodically on two occasions. Although a palatability issue with alprazolam initially prevented consistent dosing, anxious behavior was eliminated and successful breeding behavior was achieved for the first time. After 44 mo of therapy, there have been no anxious behaviors requiring additional medications, two additional breeding behaviors observed, and no evidence of adverse side effects with long-term use. PMID- 27691936 TI - EVALUATION OF ETORPHINE AND MIDAZOLAM ANESTHESIA, AND THE EFFECT OF INTRAVENOUS BUTORPHANOL ON CARDIOPULMONARY PARAMETERS IN GAME-RANCHED WHITE RHINOCEROSES (CERATOTHERIUM SIMUM). AB - Nineteen white rhinoceroses ( Ceratotherium simum ) were anesthetized with 4 mg of etorphine hydrochloride; 35-40 mg of midazolam; and 7,500 international units of hyaluronidase for dehorning purposes at a game ranch in South Africa, to investigate this anesthetic combination. Median time to recumbency was 548 sec (range 361-787 sec). Good muscle relaxation and no muscle rigidity or tremors were observed in 18 animals, and only 1 individual showed slight tremors. In addition, all animals received butorphanol i.v. 5 min after recumbency at the ratio of 10 mg of butorphanol per 1 mg of etorphine. Blood gas and selected physiologic parameters were measured in the recumbent animal, immediately before and 10 min after the administration of butorphanol. Statistically significant improvements were observed in blood gas physiologic and cardiopulmonary parameters 10 min after the administration of butorphanol, with a reduction in arterial partial pressure of carbon dioxide, systolic blood pressure, and heart rate and an increase in pH, arterial partial pressure of oxygen, oxygen saturation, and respiratory rate (all P < 0.005). After i.v. naltrexone reversal, recovery was uneventful, and median time to walking or running was 110 sec (range 71-247 sec). The results indicate etorphine and midazolam combination is an effective alternative anesthetic protocol and produces good muscle relaxation. Furthermore, i.v. butorphanol was associated with improved blood gas values and cardiopulmonary function for at least 10 min postinjection. PMID- 27691937 TI - MEASUREMENT OF INTRAOCULAR PRESSURE IN THE DOMESTIC PIGEON (COLUMBIA LIVIA). AB - The purpose of this study was to establish intraocular pressure values in clinically normal pigeons. One hundred (52 male and 48 female) healthy pigeons ( Columbia livia ) of six different breeds, ranging in age from 20 to 51 mo were used in the study. Pigeons were gently physically restrained in a dorsoventral position without any pressure or extension to the head and neck. A rebound tonometer with a disposable probe was held horizontally and 4-5 mm from the central corneal surface. Calibration of the device was set to "P." Overall, the mean +/- SD intraocular pressure values of all eyes were 6.1 +/- 0.9 mmHg (ranging from 3 to 9 mmHg). Mean +/- SD values for left and right eyes were 6.1 +/- 1.0 and 6.0 +/- 1.2 mmHg, respectively. There was no statistically significant difference in IOP between the left eye and right eye or between males and females (P = 0.49; P = 0.74). Analysis of variance revealed that there were no significant differences in the IOP between the breeds (P = 0.22).

AB - An adult, female, reef manta ray (Manta alfredi) was evaluated for abnormal swimming and coelomic distention after colliding with a floating dock in an exhibit. Initial clinical signs included abnormal posture and swimming. Clinical signs progressed to include muscle wasting, poor body condition, and coelomic distention. Further diagnostics revealed excessive exhibit substrate within the gastrointestinal tract, gastric ulcers, free coelomic fluid, possible spinal lesion, possible uterine abnormality, and hematologic changes. The ray was treated with repeated gastroscopic examinations to remove substrate from the stomach. Psyllium and mineral oil were administered in gel food to assist with passage of substrate through the gastrointestinal tract. Gastric ulcers were treated with sucralfate. Vitamin B complex, iron dextran, and Yunnan Paiyao were used to treat the anemia. Amikacin and sulfadimethoxine-ormetoprim were administered for suspected bacterial and coccidial infections, respectively. Over the course of 11 mo the ray returned to normal health.

PMID- 27691940 TI - POISONING BY THE SWAINSONINE-CONTAINING PLANT SIDA CARPINIFOLIA IN CAPTIVE SAMBAR DEER (CERVUS UNICOLOR). AB - Plant intoxications in wildlife are difficult to diagnose, are overlooked, or are sometimes even neglected. Hence, factors that induce wild animals to ingest poisonous plants have not been sufficiently documented. An outbreak of glycoprotein storage disease in sambar deer ( Cervus unicolor ), induced by ingestion of the swainsonine-containing plant, common wireweed (Sida carpinifolia), is reported. Nine out of 55 deer held by a zoo in Brazil were affected. The poisoning was characterized by emaciation and neurologic signs followed by unexpected death in some of the animals. Animals presented abnormal consciousness, posterior paresis, and musculoskeletal weakness; less evident were vestibulo-cerebellar signs. Histologically, there was vacuolation of neurons and epithelial cells of the pancreatic acines, thyroid follicules, and renal tubules. Furthermore, in the central nervous system were axonal degeneration, necrosis, and loss of neurons. Three factors may lead to the ingestion of S. carpinifolia by sambar deer: 1) A grazing field with only S. carpinifolia as a source of forage; 2) a large number of animals kept in this field; and 3) a hierarchy within a cervid group in which dominant males isolated and displaced juvenile and weaker adult males, leaving them with access to only S. carpinifolia. PMID- 27691941 TI - INFECTIOUS DISEASE AND TOXICOLOGICAL MONITORING OF STRANDED PACIFIC HARBOR SEALS (PHOCA VITULINA RICHARDSI) IN COOK INLET AS SURROGATES FOR MONITORING ENDANGERED BELUGAS (DELPHINAPTERUS LEUCAS). AB - Pacific harbor seals ( Phoca vitulina richardsi) and belugas ( Delphinapterus leucas ) eat many of the same prey species, occupy the same geographic area, and demonstrate site fidelity in Cook Inlet, Alaska. Although most direct research involving the critically endangered belugas is currently prohibited, studying harbor seals may provide important information about this beluga population. In recent years, harbor seal populations in Alaska have declined for unknown reasons. As part of its stranding program, the Alaska SeaLife Center (ASLC) managed 59 cases of live and dead stranded harbor seals from Cook Inlet between 1997 and 2011. Animals were screened for a variety of diseases and contaminants of concern. Animals were negative by serology to the following diseases: avian influenza, canine distemper virus, dolphin morbillivirus, porpoise morbillivirus, Leptospira canicola, L. grippotyphosa, L. pomona, Neospora caninum , Sarcocystis neurona , and Toxoplasma gondii . Positive titers were found against Brucella spp., phocine distemper virus, seal herpesvirus-1, L. bratislava, L. hardjo, and L. icterohemorrhagiae. All titers were stable or declining except in one animal with an increasing titer for seal herpesvirus-1. Fecal pathogen screenings identified normal flora as well as stable or declining low levels of potentially pathogenic and opportunistic bacteria, though most were of little concern for seal health. In most animals, toxicology screening showed that the majority of tested contaminants were below detectable limits. The level of evidence of exposure to pathogens of concern was low in harbor seals. Although the infectious disease burden and contaminant levels in belugas in Cook Inlet cannot be definitively determined without direct testing, pathogen and contaminant exposure is expected to be similar to that found in harbor seals in this region, as the harbor seals and belugas share the habitat and food resources.

AB - The synanthropic behavior of marsupials of the genus Didelphis in endemic areas of leishmaniasis suggests that these animals may play an important role in the epidemiology of this infection. The aim of the present study was to detect Leishmania spp. DNA in Didelphis albiventris (white-eared opossum) and Didelphis aurita (big-eared opossum) living in forested and peridomestic areas of northeastern Brazil. Blood samples were collected from 25 animals (23 D. albiventris and 2 D. aurita ) by cardiac puncture and then analyzed via PCR. Leishmania (Viannia) braziliensis DNA complex was detected in 4 (16%) of the 25 samples, whereas no samples scored positive for Leishmania (Leishmania) donovani complex. Our data suggest that D. albiventris participates in the wild enzootic cycle of the L. (V.) braziliensis complex. Therefore, humans living in this area are at risk of infection, because Didelphis species are in constant movement between wild and urban environments. PMID- 27691945 TI - PREVALENCE OF HEALED LONG-BONE FRACTURES IN WILD CARNIVORES FROM THE NORTHEASTERN UNITED STATES. AB - Museum specimens representing 12 species of terrestrial carnivores from the northeastern United States were inspected for evidence of healed long-bone fractures. Of 413 individuals, 18 (4.4%) exhibited healed fractures. Thirteen (72.2%) occurred in hind limbs; five (27.8%) occurred in forelimbs. Mustelids had the highest prevalence of healed long-bone fractures (38.8%) of all observed fractures. Within family, 5.6% of Canidae and 2.8% of Mustelidae exhibited healed fractures. Bobcats had the highest taxon prevalence of fractures, 18%. Observational data to assess use of and behavior near roads could provide insight to causes of fracture. Capture in combination with noninvasive examination techniques could be employed to determine incidence of healed fractures in wild populations. Individuals with healed fractures could then be tracked via radio telemetry to determine if these animals behave differently than uninjured conspecifics, and assess long-term survivability and fitness. PMID- 27691946 TI - PLASMA BIOCHEMISTRY AND HEMATOLOGY REFERENCE VALUES OF CAPTIVE PANTHER CHAMELEONS (FURCIFER PARDALIS) WITH SPECIAL EMPHASIS ON SEASONALITY AND GENDER DIFFERENCES. AB - Blood samples of 86 captive panther chameleons (Furcifer pardalis) were collected in January and August from the ventral coccygeal vein in order to establish reference intervals of clinical healthy individuals under similar husbandry conditions for plasma biochemistry and hematology for this species. Significant differences were found in phosphorus, glucose, total protein, albumin, and white blood cell count between males and females in both seasons. Calcium, alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase varied in only one season between genders. Significant differences between summer and winter values were present in both genders for uric acid, calcium, phosphorus, glucose, total protein, creatine kinase, and albumin. Additionally, females showed seasonal variations for alanine aminotransferase and aspartate aminotransferase whereas packed cell volume varied in males. Gravid females had significantly higher body weights and increased values for uric acid, calcium, phosphorus, alanine aminotransferase, total protein, and albumin. Cytomorphologic characteristics of blood cells in stained blood films were evaluated to serve as additional parameters for hematology. PMID- 27691947 TI - PHARMACOKINETIC EVALUATION OF MELOXICAM AFTER INTRAVENOUS AND INTRAMUSCULAR ADMINISTRATION IN NILE TILAPIA (OREOCHROMIS NILOTICUS). AB - Critically evaluating the pharmacokinetic behavior of a drug in the body provides crucial information about how to effectively treat a patient. Pharmacokinetic studies that exist in fish have primarily focused on drugs used to treat infectious disease, with minimal attention given to analgesic drugs. The objective of this study was to determine the pharmacokinetics of meloxicam (1 mg/kg) in Nile tilapia ( Oreochromis niloticus ) (n = 12). A single dose of meloxicam was administered either i.v. or i.m. Blood samples were obtained at predetermined times after drug injection. Plasma meloxicam concentrations were determined by a validated liquid chromatography/mass spectrometry method, and noncompartmental pharmacokinetic analysis was performed. The mean peak plasma concentration after i.m. injection was 1.95 MUg/ml. The mean terminal half-life of meloxicam after i.v. and i.m. administration was 1.36 and 1.8 hr, respectively. The area under the plasma concentration-versus-time curve extrapolated to infinity was 11.26 hr.MUg/ml after i.v. administration and 5.72 hr.MUg/ml after i.m. administration. Bioavailability of meloxicam after i.m. administration was approximately half that of i.v. administration. Elimination was rapid in both the i.m. and i.v. routes of administration, suggesting that maintaining clinically relevant plasma concentrations may be difficult using this dose. This study represents the first pharmacokinetic evaluation of a nonsteroidal anti-inflammatory drug in a fish species, and further studies evaluating efficacy are needed. PMID- 27691948 TI - RADIOGRAPHIC THORACIC ANATOMY OF THE RED PANDA (AILURUS FULGENS). AB - The red panda ( Ailurus fulgens ) is classified as an endangered species by the International Union for Conservation of Nature and Natural Resources. The natural distribution of the red panda is in the Himalayas and southern China. Thoracic diseases such as dirofilariasis, hypertrophic cardiomyopathy, tracheal obstruction, lung worm infestation, and pneumonia have been reported in the red panda. The aim of this study was to describe the normal radiographic thoracic anatomy of captive red pandas as a species-specific reference for routine health examinations and clinical cases. Right lateral (RL) and dorsoventral (DV) inspiratory phase views of the thorax were obtained in 11 adult captive red pandas. Measurements were made and ratios calculated to establish reference ranges for the mean vertebral heart score on the RL (8.34 +/- 0.25) and DV (8.78 +/- 0.34) views and the mean ratios of the caudal vena cava diameter to the vertebral body length above tracheal bifurcation (0.67 +/- 0.05) and tracheal diameter to the width of the third rib (2.75 +/- 0.24). The majority of animals (10/11) had 14 thoracic vertebrae, except for one animal that had 15 thoracic vertebrae. Rudimentary clavicles were seen in 3/11 animals. The ovoid, oblique cardiac silhouette was more horizontally positioned and elongated in older animals. A redundant aortic arch was seen in the oldest animal. The trachea was seen with mineralized cartilage rings in all animals. The carina was clearly seen in the majority of animals (10/11). Variations exist in the normal radiographic thoracic anatomy of different species. Knowledge of the normal radiographic thoracic anatomy of the red panda should prove useful for routine health examinations and in the diagnosis of thoracic diseases.

This is the first comprehensive report of hematology and plasma biochemistry parameters in apparently healthy California tiger salamanders and may serve as a reference for clinical assessment and future study of this species. PMID- 27691951 TI - BILATERAL HYDRONEPHROSIS IN A SUGAR GLIDER (PETAURUS BREVICEPS). AB - An adult, intact male sugar glider ( Petaurus breviceps ) presented for acute caudal abdominal swelling. Treatment by the referring veterinarian included aspiration of urine from the swelling. On physical examination, mild depression, pale mucus membranes, and caudal abdominal swelling were noted. Focused ultrasonographic assessment revealed a fluid-filled caudal abdominal structure and subjective bladder wall thickening. The following day, the sugar glider was severely depressed. Hematology results included hypoglycemia, hyperkalemia, hyponatremia, and azotemia. Ultrasonography revealed bilateral hydronephrosis and hydroureter. Despite supportive care, the animal died. Postmortem examination confirmed bilateral ureteral dilation, renal petechial hemorrhage, and dilation of the right renal pelvis. Submucosal edema, hemorrhage, and lymphoplasmacytic infiltration of the urinary bladder, ureters, and renal pelvises were noted. Hyperplasia of the urinary bladder and ureteral epithelium, coupled with inflammation, may have caused functional obstruction leading to bilateral hydronephrosis and hydroureter. This is the first reported case of hydronephrosis in a marsupial. PMID- 27691950 TI - CARDIOVASCULAR EFFECTS OF ETORPHINE, AZAPERONE, AND BUTORPHANOL COMBINATIONS IN CHEMICALLY IMMOBILIZED CAPTIVE WHITE RHINOCEROS (CERATOTHERIUM SIMUM). AB - Chemical capture is an essential tool in the management and conservation of white rhinoceros ( Ceratotherium simum ); however, cardiovascular responses in immobilized megaherbivores are poorly understood. Blood pressure and heart rate responses in rhinoceros immobilized with etorphine or etorphine plus azaperone, and the effects of subsequent i.v. butorphanol administration were investigated. Six white rhinoceros were used in a randomized crossover study design with four interventions: 1) etorphine i.m.; 2) etorphine plus azaperone i.m.; 3) etorphine i.m. and butorphanol i.v.; and 4) etorphine plus azaperone i.m., and butorphanol i.v. Etorphine resulted in hypertension and tachycardia in immobilized rhinoceros on initial measurements. Over the 25-min study period, blood pressures and heart rate declined. Heart rates were slower, although the rhinoceros were still tachycardic, and blood pressures lower during the whole study period in animals immobilized with etorphine and azaperone compared with those that received only etorphine. Butorphanol administration resulted in lower arterial blood pressures and heart rates in etorphine-immobilized rhinoceros. In rhinoceros immobilized with etorphine and azaperone, heart rate slowed following administration of butorphanol i.v., although blood pressures remained unchanged. Azaperone reduced hypertension associated with etorphine immobilization, but animals remained tachycardic. Administration of butorphanol to etorphine/azaperone-immoblized rhinoceros lowered heart rate to values approaching normal resting levels without altering blood pressure. PMID- 27691952 TI - GROSS ANATOMY AND SURGICAL APPROACH TO THE HUMERAL SHAFT IN GIANT ANTEATER (MYRMECOPHAGA TRIDACTYLA). AB - Anteater forelimbs are distinguished morphologically from domestic animals, especially due to their unique movement and their natural habits. A knowledge of the pectoral limb anatomy and the proper surgical approach are fundamental to success in osteosynthesis and other surgeries. This study aimed to describe the muscles and neurovascular structures of the pectoral limb and the surgical approach to the humeral shaft of the giant anteater ( Myrmecophaga tridactyla ). Dissections of the forelimbs of seven cadavers were performed to identify the major muscles and neurovascular structures. Three of these animals' contralateral forearms were used to simulate the surgical approach to the humeral shaft. Some specific characteristics of the muscle morphology were biceps muscle had two heads, triceps muscle had three heads, and there was an olecranon-epicondylar muscle. To expose the shaft of the humerus, it was necessary to incise the superficial pectoral muscle and separate the heads of the biceps muscle. Due to the anatomical characteristics of the humerus, the craniomedial approach was the most appropriate because it accommodated the anatomical peculiarities of the giant anteater. PMID- 27691953 TI - PROSPECTIVE POPULATION MANAGEMENT FOR HEPATITIS B IN THE CHIMPANZEE (PAN TROGLODYTES) SSP(r) POPULATION. AB - Hepatitis B virus causes horizontally transmitted infectious hepatopathy of primates and may progress to hepatocellular carcinoma. Historically, a small number of chimpanzees ( Pan troglodytes ) living in accredited North American zoos have been confirmed with positive hepatitis B serology consistent with exposure. However, the overall status for this population and the interpretation of these individual test results have not been established previously. The current U.S. zoo-housed population (n = 259) was assessed serologically for hepatitis B by surface protein antigen (HbsAg) and surface antibodies (anti-Hbs). Signalment, origin, current health status, history of liver disease, and hepatitis B vaccination history were obtained for each animal. Serologic status was measured directly in 86.5% (n = 224) of these individuals, with 2.2% (n = 5) of the study population determined to be chronically infected by positive HbsAg and negative anti-Hbs status. Additionally, 11.6% (n = 26) of the directly measured population tested were HbsAg negative and anti-Hbs positive, which was indicative of viral exposure. No animals were determined to be acutely infected as HbsAg and anti-Hbs positive. Although these results demonstrated a relatively low prevalence of hepatitis B infection among these chimpanzees, the varied serologic results between institutions underscored the importance of routine serologic testing, especially at times of proposed transfers, and consideration of species vaccination protocols. PMID- 27691954 TI - DETECTION OF COXIELLA BURNETII INFECTION IN A SAHARAWI DORCAS GAZELLE (GAZELLA DORCAS NEGLECTA). AB - Coxiella burnetii, the causative agent of Q fever, can infect a wide range of host species, but limited information exists on the occurrence and implications of infection in wild species. This study describes a natural infection in a population of dorcas gazelles ( Gazella dorcas ) from a zoo. A 9-yr-old male Saharawi dorcas gazelle ( Gazella dorcas neglecta) tested positive on enzyme linked immunosorbent assay (ELISA) and fecal polymerase chain reaction (PCR). Despite treatment with oxytetracycline, the animal did not clear the infection after 6 mo, as confirmed by a PCR test on a semen sample. This is the first report of a Saharawi dorcas gazelle infection with C. burnetii and the first time that C. burnetii was detected in semen from a zoo animal, suggesting the possibility of venereal transmission in captive wild species. This may have major implications for management of zoo populations, particularly in endangered species. PMID- 27691955 TI - DIVERSITY OF THE TYPE 1 INTRON-ITS REGION OF THE 18S rRNA GENE IN PSEUDOGYMNOASCUS SPECIES FROM THE RED HILLS OF KANSAS. AB - Gypsum caves found throughout the Red Hills of Kansas have the state's most diverse and largest population of cave-roosting bats. White-nose syndrome (WNS), a disease caused by the fungus Pseudogymnoascus destructans, which threatens all temperate bat species, has not been previously detected in the gypsum caves as this disease moves westward from the eastern United States. Cave soil was obtained from the gypsum caves, and using the polymerase chain reaction, a 624 nucleotide DNA fragment specific to the Type 1 intron-internal transcribed spacer region of the 18S rRNA gene from Pseudogymnoascus species was amplified. Subsequent cloning and DNA sequencing indicated P. destructans DNA was present, along with 26 uncharacterized Pseudogymnoascus DNA variants. However, no evidence of WNS was observed in bat populations residing in these caves. PMID- 27691956 TI - MOLECULAR IDENTIFICATION AND SEQUENCE CHARACTERIZATION OF MYCOPLASMAS IN FREE LIVING BIRDS OF PREY. AB - Mycoplasma spp. have been detected in birds of prey, but their prevalence in free living raptors and their significance to birds' health need further investigation. Molecular techniques have been increasingly used to identify mycoplasmas in various avian species, due to the fastidious nature of these pathogens hampering traditional bacteriologic tests. This study reports the identification of 23 novel mycoplasma sequences during the monitoring of 62 birds of prey on admission to wildlife centers in Sardinia, Italy. Molecular investigation performed on pharyngeal swabs revealed 26 birds positive to Mycoplasma (42%). Sequence analysis based on 16S rRNA, 16S-23S rRNA intergenic spacer, and RNA polymerase beta subunit (rpoB) gene highlighted cluster assignment and phylogenetic relationships among the identified types, classified within the hominis group. Additionally, Ornithobacterium rhinotracheale , associated with respiratory disease in poultry, was identified in 17 birds (27%). Potential coinfection and mycoplasma opportunistic nature present implications for raptor species conservation.

AB - Skin diseases affect millions of people and animals worldwide, including Asian elephants. This study sought to determine the pathogen of skin diseases that occurred in Asian elephants in Chongqing Zoo, China. The isolated fungus was identified through its cultural characteristics, morphology, and polymerase chain reaction (PCR) amplification. The PCR amplification using common fungal primers (ITS1 and ITS4) determined that the pathogen was 99.7% homologous to Microsporum canis. This is the first report on elephants infected with Microsporum canis in China. PMID- 27691958 TI - RETROSPECTIVE ANALYSIS OF ADULT-ONSET CARDIAC DISEASE IN FRANCOIS' LANGURS (TRACHYPITHECUS FRANCOISI) HOUSED IN U.S. ZOOS. AB - Cardiac disease is a common condition in captive primates, and multiple cases in Francois' langurs ( Trachypithecus francoisi ) were noted on review of the Species Survival Plan studbook. To determine the prevalence of cardiac disease in this species, surveys were distributed to current and previous holding institutions (n = 23) for the U.S. studbook population (n = 216). After exclusion of stillbirths (n = 48), animals less than 1 yr of age (n = 8), and animals housed internationally (n = 2), a study group (n = 158) was identified for this analysis. Robust data was received for 98.7% (n = 156) of the study group and antemortem and postmortem cardiac abnormalities were reported for 25.3% (n = 40) of these animals. Eight animals were reported as medically managed for clinical cardiac disease, and three of these were alive at the time of survey. Six of 11 animals with radiographic cardiac silhouette enlargement antemortem were noted with cardiomegaly on postmortem examination. Of 102 deceased animals in the study group, four were identified with dilated cardiomyopathy, and varying degrees of myocardial fibrosis was observed in 18 animals. Langurs with cardiac fibrosis were found to be significantly older than langurs without cardiac fibrosis (P = 0.003) and more commonly were male (P = 0.036). Screening tests for cardiac disease, such as thoracic radiographs and echocardiography, are recommended to diagnose affected animals earlier, to monitor progression of disease, and to guide treatment, although they should be interpreted with caution because of apparent insensitivity when compared with pathologic results. PMID- 27691959 TI - TREATMENT OF DIABETES MELLITUS IN A GOLDEN LION TAMARIN (LEONTOPITHECUS ROSALIA) WITH THE GLUCAGON-LIKE PEPTIDE-1 MIMETIC EXENATIDE. AB - An 8-yr-old male golden lion tamarin ( Leontopithecus rosalia ) was diagnosed with diabetes mellitus based on hyperglycemia and persistent glycosuria. Initial treatment consisted of the oral antihyperglycemic medications glipizide and metformin that resulted in decreased blood glucose concentrations; however, marked glycosuria persisted. Insufficient improvement on oral antihyperglycemic therapy and poor feasibility of daily subcutaneous insulin therapy led to an investigation into an alternative therapy with extended-release exenatide, a glucagon-like peptide-1 (GLP-1) mimetic, at a dosage of 0.13 mg/kg subcutaneously once per month. Following treatment with exenatide, the persistent glycosuria resolved, the animal maintained normal blood glucose concentrations, and had lower serum fructosamine concentrations compared to pretreatment levels. Based on these findings, extended-release exenatide could be considered as a therapeutic option in nonhuman primates with diabetes mellitus that do not respond to oral antihyperglycemics and in which daily subcutaneous insulin is not feasible. PMID- 27691960 TI - EVALUATION OF SERUM FERRITIN AND SERUM IRON IN FREE-RANGING BLACK RHINOCEROS (DICEROS BICORNIS) AS A TOOL TO UNDERSTAND FACTORS AFFECTING IRON-OVERLOAD DISORDER. AB - Iron overload disorder (IOD) is a significant health issue for captive black rhinoceros ( Diceros bicornis ). Measurement of serum ferritin with a validated rhinoceros ferritin ELISA has been used extensively to detect animals in U.S. zoos that are at risk of developing IOD. However, there is limited information on serum ferritin levels in free-ranging black rhinoceros using this same assay. Serum ferritin, iron, and gamma-glutamyl transpeptidase (GGT) were determined in 194 black rhinoceros from southern Africa. Mean ferritin in free-ranging black rhinoceros (290.54 +/-247.4 ng/ml) was significantly higher than in free-ranging white rhinoceros (64.0 +/- 102.4 ng/ml) sampled in this study from Kruger National Park, South Africa. However, there were no significant differences between genders or age groups. Ferritin values varied with geographical location of the black rhinoceros, although this was not clinically significant. Serum iron values were also higher in black rhinoceros (40.4 +/- 19.1 MUmol/L) compared to white rhinoceros (29.7 +/- 10.7 MUmol/L). There was no association between ferritin and GGT. This study provides serum ferritin, iron, and GGT values from free-ranging black rhinoceros that can be used for as comparative target values for captive animals.

AB - A female Southern black rhinoceros ( Diceros bicornis minor) calf died unexpectedly at less than 12 hr of age, after an uncomplicated birth and uneventful early postpartum period. Gross necropsy revealed a 15-cm full thickness cleft palate, a patent foramen ovale, and four septal defects ranging from 0.3 to 1 cm in diameter. Histologic findings did not reveal any significant abnormalities. Karyotyping did not indicate any significant numerical or structural chromosomal abnormalities. PMID- 27691962 TI - CUTANEOUS SQUAMOUS CELL CARCINOMA IN A PANTHER CHAMELEON (FURCIFER PARDALIS) AND TREATMENT WITH CARBOPLATIN IMPLANTABLE BEADS. AB - A 3-yr-old male panther chameleon (Furcifer pardalis) presented with bilateral raised crusted skin lesions along the lateral body wall that were found to be carcinoma in situ and squamous cell carcinoma. Similar lesions later developed on the caudal body wall and tail. A subcutaneous implantable carboplatin bead was placed in the first squamous cell carcinoma lesion identified. Additional new lesions sampled were also found to be squamous cell carcinomas, and viral polymerase chain reaction was negative for papillomaviruses and herpesviruses. Significant skin loss would have resulted from excision of all the lesions, so treatment with only carboplatin beads was used. No adverse effects were observed. Lesions not excised that were treated with beads decreased in size. This is the first description of cutaneous squamous cell carcinoma and treatment with carboplatin implantable beads in a panther chameleon. PMID- 27691963 TI - EVALUATION OF POTENTIAL RISK FACTORS ASSOCIATED WITH CATARACT IN CAPTIVE MACARONI (EUDYPTES CHRYSOLOPHUS) AND ROCKHOPPER PENGUINS (EUDYPTES CHRYSOCOME). AB - Complete ophthalmic examinations were performed on 160 Macaroni penguins ( Eudyptes chrysolophus ) and 90 Rockhopper penguins ( Eudyptes chrysocome ) at eight North American zoological institutions. Cataract prevalence in the Macaroni population was 46.5% (n = 74) of penguins and 42.3% (135/319) of eyes. Cataract prevalence in the Rockhopper population was 45.5% (n = 40) of penguins and 40.6% (73/180) of eyes. The mean age of Macaroni penguins without ocular disease was 7.4 +/- 5.8 yr, while that of Rockhoppers was 9.8 +/- 6.4 yr. Risk factors for cataract were examined through husbandry surveys completed by each institution and by evaluation of light intensity and ultraviolet (UV) light measurements acquired in each penguin exhibit. Risk factors associated with cataract in Macaroni penguins included age, dietary smelt, hand-feeding, and fluorescent exhibit lighting. Risk factors associated with cataract in Rockhopper penguins included age, dietary capelin, increasing population density, and increasing length of minimum photoperiod. Factors associated with decreased odds of cataract in Macaroni penguins included saltwater pool, monitoring of water quality for salinity, pH, and alkalinity; use of water additives; presence of pool filtration and sterilization systems; use of metal halide lightbulbs; increasing light intensity; and UV spectrum lighting. Factors associated with decreased odds of cataract in Rockhoppers included dietary herring and krill, increasing exhibit land area, pool temperature monitoring, increasing maximum photoperiod, and increasing minimum UV light.

AB - A hand-reared, 53-kg, female, 30-day-old black rhinoceros ( Diceros bicornis ) calf presented for magnetic resonance imaging and computed tomography after demonstrating neurologic signs. The rhino was premedicated intramuscularly with butorphanol and midazolam, yielding satisfactory sedation. Induction was achieved using intravenous propofol until the trachea could be intubated. Anesthesia was maintained with sevoflurane in 100% oxygen (mean end-tidal concentration of 2 +/- 0.5%). Mean values recorded during anesthesia included were heart rate, end-tidal carbon dioxide, respiratory rate, noninvasive blood pressure, and pulse oximetry. A balanced electrolyte solution of 10 mL/kg per hour was given intravenously. It was concluded that anesthesia was safely induced and maintained with a combination of butorphanol, midazolam, propofol, and sevoflurane. Total anesthesia time was 3 hr, with no perianesthetic complications and an uneventful recovery. PMID- 27691966 TI - INVESTIGATION ON CRYPTOSPORIDIUM INFECTIONS IN WILD ANIMALS IN A ZOO IN ANHUI PROVINCE. AB - To assess Cryptosporidium infections among wild animals in a zoo located in Anhui province, we conducted an investigation on the fecal samples collected from 44 primates, 41 herbivores, 44 carnivores and omnivores, and 103 birds in the zoo with the use of Sheather's sugar flotation technique and modified acid-fast staining. Cryptosporidium oocysts were detected in the fecal samples from six primates, two herbivores, four carnivores and omnivores, and seven birds by using Sheather's sugar flotation technique; the prevalence of Cryptosporidium infection in primates, herbivores, carnivores and omnivores and birds was 13.64, 4.88, 9.09, and 6.80%, respectively. Modified acid-fast staining detected the presence of Cryptosporidium oocysts in the fecal samples of one primate, three herbivores, 0 carnivores and omnivores, and one bird, and the prevalence of Cryptosporidium infection in primates, herbivores, carnivores and omnivores and birds was 2.27, 7.32, 0.00, and 0.97%, respectively. Polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) and phylogenetic analysis with the use of the neighbor-joining (NJ) method based on the aligned partial small-subunit (SSU) rRNA gene sequences showed that the protozoan pathogen isolated from primates was Cryptosporidium hominis and the pathogen isolated from camels ( Camelus dromedarius ) was Cryptosporidium andersoni. Subtyping the Cryptosporidium hominis by 60-kDa glycoprotein (GP60) gene phylogenetic analysis showed the Cryptosporidium hominis belongs to the subtype IdA and IbA.

AB - This report describes the pharmacokinetic profiles of chronically administered oral isoniazid and rifampin in one adult male and one adult female Asian elephant ( Elephas maximus ) that were asymptomatically infected with Mycobacterium tuberculosis . Rifampin's half-life was reduced when compared to previous single dose pharmacokinetic profiles of healthy uninfected Asian elephants. Both elephants experienced delayed absorption of isoniazid and rifampin as compared to previous pharmacokinetic studies in this species. The altered pharmacokinetics of both drugs in repeated-dosing clinical situations underscores the need for individual therapeutic drug monitoring for tuberculosis treatment.

AB - Hypercholesterolemia is common in psittacines, and Amazon parrots ( Amazona spp.) are particularly susceptible. Associations have been demonstrated between naturally occurring and experimentally induced hypercholesterolemia and atherosclerosis in psittacines. Daily exercise improves lipid metabolism in humans and other mammals, as well as pigeons and chickens, under varying experimental conditions. Hispaniolan Amazon parrots ( Amazona ventralis ) with naturally occurring hypercholesterolemia (343-576 mg/dl) were divided into two groups. An exercised group (n = 8) was housed as a flock and exercised daily with 30 min of aviary flight and 30 min walking on a rotating perch. A sedentary control group (n = 4) was housed in individual cages with no exercise regime. A plasma lipid panel, including total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, and triglycerides, was validated for this species. Body weight, chest girth, and the lipid panel were measured at 0, 61, and 105 days. Hematology and plasma biochemistry were measured at 0 and 105 days. Weight and girth were significantly lower in exercised than sedentary parrots at 61 and 105 days. HDL-C concentrations were significantly higher in exercised parrots at 61 days but returned to near baseline by 105 days. There were no significant changes in hematology, biochemistry, or other lipid panel parameters. Results were similar to studies in humans and animal models, in which increased HDL-C was the most consistent effect of exercise on circulating lipid and lipoprotein parameters. The return toward baseline HDL-C may have resulted from decreased participation in aviary flight. Additional investigation will be required to determine the amount of exercise and change in circulating lipid-related parameters necessary to improve long-term wellness in psittacine species predisposed to hypercholesterolemia.

AB - Recurrent eosinophilic granuloma (EG) in two captive eastern black rhinoceros ( Diceros bicornis michaeli) was effectively managed with glucocorticoids and antihistamines. The first case was a female and the second case was a male. The animals were housed at separate institutions and initially presented with hemorrhagic oral lesions. Multifocal lesions occurred in the second case. Multiple biopsies were taken from each animal, all of which were consistent with EG. Each animal was anesthetized multiple times for surgical treatment but experienced frequent recurrence. Due to lack of response to therapy and the risks and adverse events associated with repeated anesthesia, medical treatment was initiated in both cases using a tapering dose of oral dexamethasone. The lesions dramatically improved, but would recur frequently after treatment. Hydroxyzine, an oral antihistamine, greatly reduced the incidence and severity of the lesions. Medical management with glucocorticoids and antihistamines minimized stressful anesthetic events in both cases and contributed to the successful management of this recurrent disease. The exact pathogenesis of EG in black rhinoceros remains unknown but response to antihistamines suggests an allergic etiology. PMID- 27691970 TI - MYOSITIS OSSIFICANS TRAUMATICA IN A VAMPIRE BAT (DESMODUS ROTUNDUS). AB - A 15-yr-old sexually intact female vampire bat ( Desmodus rotundus ) was diagnosed with myositis ossificans traumatica of the abdominal wall. The bat presented with a large ulcerated firm mass along the abdomen. Radiographs and cytology were performed, followed by surgical exploration. The mass was determined to be nonresectable and the bat was euthanized. Histopathology showed severe necrotizing, degenerative, and pyogranulomatous myositis with osseous and cartilaginous metaplasia, fibrosis, and ulceration, which were consistent with myositis ossificans traumatica. Myositis ossificans traumatica is commonly associated with previous trauma to skeletal muscle. Two years prior, this bat had an emergency Caesarian section at this site, which was postulated to elicit a marked tissue response leading to this condition. Myositis ossificans traumatica is infrequently reported in humans, dogs, cats, pigs, and horses. To the author's knowledge, this is the first report of this condition in a bat. PMID- 27691971 TI - SYSTEMIC BLASTOMYCOSIS IN A CAPTIVE RED RUFFED LEMUR (VARECIA RUBRA). AB - A 5-yr-old, intact male red ruffed lemur ( Varecia rubra ) presented for evaluation as the result of a 1-wk history of lethargy and hyporexia. Physical examination findings included thin body condition, muffled heart sounds, harsh lung sounds, and liquid brown diarrhea. Complete blood count and serum biochemistry showed an inflammatory leukogram, mild hyponatremia, and mild hypochloremia. Orthogonal trunk radiographs revealed a severe alveolar pattern in the right cranial lung lobes with cardiac silhouette effacement. Thoracic ultrasound confirmed a large, hypoechoic mass in the right lung lobes. Fine needle aspiration of the lung mass and cytology revealed fungal yeast organisms, consistent with Blastomyces dermatitidis. Blastomyces Quantitative EIA Test on urine was positive. Postmortem examination confirmed systemic blastomycosis involving the lung, tracheobronchial lymph nodes, spleen, kidney, liver, cerebrum, and eye. To the authors' knowledge, this is the first report of blastomycosis in a prosimian species. PMID- 27691972 TI - SURGICAL CORRECTION OF TRAUMATIC PATELLAR LUXATION IN AN EURASIAN LYNX (LYNX LYNX). AB - The aim of this report is to describe the successful surgical repair of a traumatic medial patellar luxation in a 4-yr-old female Eurasian lynx ( Lynx lynx ). The animal presented with hind limb lameness. Physical and radiographic examinations were performed under sedation. After diagnosing a medial patellar luxation, surgical repair was recommended. A combination of soft tissue reconstructive techniques was used to repair the medial patellar luxation. The limb was not immobilized postoperatively, but the animal was confined to a cage for 1 mo. The recovery was uneventful and return to normal activity was observed within 1 mo. Soft tissue reconstructive techniques can be used as the only surgical treatment for the repair of a traumatic patellar luxation in both domestic and wild animals. PMID- 27691973 TI - XENOTRANSFUSION IN AN ISLAND FOX (UROCYON LITTORALIS CLEMENTAE) USING BLOOD FROM A DOMESTIC DOG (CANIS LUPUS FAMILIARIS). AB - Successful xenotransfusion in an island fox ( Urocyon littoralis clementae) has not been previously reported but may be necessary in an emergency. An 11-yr-old male, intact, captive island fox was exhibiting clinical signs of rattlesnake envenomation including hypoperfusion, tachypnea, facial edema, and multifocal facial and cervical ecchymosis. Blood work revealed severe thrombocytopenia (18 K/MUl) and anemia (Hct 15.8%). A presumptive diagnosis of rattlesnake ( Crotalus sp.) envenomation was made. Initial treatment included oxygen therapy, fluid therapy, antibiotics, antacids, pain medications, and polyvalent crotalid anti venom. Emergency xenotransfusion using whole blood (45 ml) from a domestic dog was used due to worsening clinical signs from anemia. No acute or delayed transfusion reactions were observed in the fox and the patient made a full recovery 5 days later. Successful xenotransfusion in an island fox using whole blood from a domestic dog ( Canis lupus familiaris) is possible and may be lifesaving. PMID- 27691974 TI - ESTABLISHMENT OF A FIBRINOGEN REFERENCE INTERVAL IN ORNATE BOX TURTLES (TERRAPENE ORNATA ORNATA). AB - This study sought to establish a reference interval for fibrinogen in healthy ornate box turtles ( Terrapene ornata ornata). A total of 48 turtles were enrolled, with 42 turtles deemed to be noninflammatory and thus fitting the inclusion criteria and utilized to estimate a fibrinogen reference interval. Turtles were excluded based upon physical examination and blood work abnormalities. A Shapiro-Wilk normality test indicated that the noninflammatory turtle fibrinogen values were normally distributed (Gaussian distribution) with an average of 108 mg/dl and a 95% confidence interval of the mean of 97.9-117 mg/dl. Those turtles excluded from the reference interval because of abnormalities affecting their health had significantly different fibrinogen values (P = 0.313). A reference interval for healthy ornate box turtles was calculated. Further investigation into the utility of fibrinogen measurement for clinical usage in ornate box turtles is warranted. PMID- 27691975 TI - HEPATIC OSTEODYSTROPHY IN A GOLDEN LION TAMARIN (LEONTOPITHECUS ROSALIA). AB - An 8-yr-old, captive, female golden lion tamarin ( Leontopithecus rosalia ) with a 6-yr history of hyperbilirubinemia was examined for inappetence and weight loss. Physical examination and blood pressure monitoring under anesthesia revealed hypothermia and hypotension, and blood work revealed hypoglycemia, markedly elevated liver enzymes, including serum alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase, and confirmed the hyperbilirubinemia. A complete blood count suggested chronic lymphoid leukemia. The animal's condition deteriorated during recovery, and the animal died despite aggressive treatment. Grossly, there was micronodular cirrhosis of the liver, severe icterus, and diffuse osteopenia of all examined bones. Microscopic examination of the liver confirmed the micronodular cirrhosis and bone lesions were compatible with diffuse osteopenia and osteomalacia. This brief communication presents a case of chronic liver disease and lesions indicative of metabolic bone disease, also known as hepatic osteodystrophy. To the authors' knowledge, this is the first documented case of hepatic osteodystrophy in the veterinary literature. PMID- 27691976 TI - NEPHROPATHIES IN THE EUROPEAN CAPTIVE CHEETAH (ACINONYX JUBATUS) POPULATION. AB - According to previous studies in captive cheetah ( Acinonyx jubatus ) populations, one of the most threatening diseases besides amyloidosis, myelopathy, veno occlusive disease, and gastritis, is renal failure. Contrary to captive cheetahs in North America and South Africa, morphological data concerning renal lesions in the cheetah European Endangered Species Program (EEP) are lacking. This study details the histological characterization as well as immunohistochemical and morphometrical analysis of nephropathies in 35 captive cheetahs from the EEP, which were necropsied between 1985 and 2003. Examination of paraffin- and glycolmethacrylate-methylmethacrylate (GMA-MMA) embedded kidney samples by light microscopy revealed glomerulonephritis in 91%, with a high prevalence for glomerulosclerosis and glomerulonephritis with the histologic pattern of membranous glomerulonephritis (77%). Besides these predominating glomerulopathies, a wide range of other renal lesions, like acute tubular necrosis, interstitial nephritis, calcinosis, and amyloidosis, were present. Pathological expression of collagen type IV, complement C3, fibronectin, and IgG was demonstrated in the glomeruli of the cheetah kidneys with the use of the avidin-biotin complex method. Morphometrical analysis was performed on GMA-MMA embedded kidney samples to obtain glomerulosclerosis index and glomerulosclerosis incidence. PMID- 27691977 TI - A SYSTEMATIC REVIEW OF THE LITERATURE RELATING TO CAPTIVE GREAT APE MORBIDITY AND MORTALITY. AB - Wild bonobos (Pan paniscus), chimpanzees (Pan troglodytes), Western gorillas (Gorilla gorilla), and orangutans (Pongo pygmaeus, Pongo abelii) are threatened with extinction. In order to help maintain a self-sustaining zoo population, clinicians require a sound understanding of the diseases with which they might be presented. To provide an up-to-date perspective on great ape morbidity and mortality, a systematic review of the zoological and veterinary literature of great apes from 1990 to 2014 was conducted. This is the first review of the great ape literature published since 1990 and the first-ever systematic literature review of great ape morbidity and mortality. The following databases were searched for relevant articles: CAB Abstracts, Web of Science Core Collection, BIOSIS Citation Index, BIOSIS Previews, Current Contents Connect, Data Citation Index, Derwent Innovations Index, MEDLINE, SciELO Citation Index, and Zoological Record. A total of 189 articles reporting on the causes of morbidity and mortality among captive great apes were selected and divided into comparative morbidity-mortality studies and case reports-series or single-disease prevalence studies. The content and main findings of the morbidity-mortality studies were reviewed and the main limitations identified. The case reports-case series and single-disease prevalence studies were categorized and coded according to taxa, etiology, and body system. Subsequent analysis allowed the amount of literature coverage afforded to each category to be calculated and the main diseases and disorders reported within the literature to be identified. This review concludes that reports of idiopathic and infectious diseases along with disorders of the cardiovascular, respiratory, and gastrointestinal body systems were particularly prominent within the great ape literature during 1990-2014. However, recent and accurate prevalence figures are lacking and there are flaws in those reviews that do exist. There is therefore a critical need for a robust, widespread, and more up-to-date review of mortality among captive great apes. PMID- 27691978 TI - The Role of microRNA in Ischemic and Hemorrhagic Stroke. AB - BACKGROUND: Stroke is the second leading cause of death worldwide. Understanding of gene expression dynamics could bring new approaches in diagnostics and therapy of stroke. Small noncoding molecules termed "microRNA" represent the most flexible network of gene expression regulators. METHOD: The aim of this review was to briefly describe the structure and function of microRNA and summarize the current knowledge about the involvement of microRNAs in the pathophysiology of ischemic and hemorrhagic stroke based on both experimental and clinical studies. RESULTS: Numerous profiling studies identified candidate microRNAs and partially described dynamics of their expression after the stroke. However, complex associations of specific microRNAs expression with main clinical characteristics and deeper insight into mechanisms of their regulatory functions are still missing. In this review, we put special emphasis on several microRNA clusters involved in neuroprotection (miR-124, miR-181, miR-21, miR-29, miR-210 and let7). Potential application of microRNAs as biomarkers and diagnostic or therapeutic targets was also discussed. CONCLUSION: Full understanding of the regulatory mechanisms of the microRNA networks represents a novel direction for stroke research. To date, we do not have effective tools to control pathophysiological processes associated with stroke. Thus the microRNAs have to be considered as a very promising target for future stroke therapies. PMID- 27691980 TI - Why is the topic of the biological embedding of experiences important for translation? AB - Translational research focuses on innovation in healthcare settings, but this is a two-way process that may have implications for either treatment or prevention. Smoking and lung cancer and the fetal alcohol syndrome are used as examples. Experimental medicine that budges basic and clinical science often constitutes a key way forward. Areas of scientific progress and challenge are discussed in relation to drug action, social cognition, cognitive neuroscience, molecular genetics, gene-environment interaction, and epigenetics. Key concepts and challenges in relation to stress include toxicity, allostatic load, the hypothalamus-pituitary-adrenal axis, and objectives versus subjective stress. The reasons for the need to test causal inferences are discussed. Various kinds of "natural experiments" are discussed in illustration using the assisted conception design, the discordant monozygotic twin design, and the study of universal exposure. Animal models are discussed in relation to enrichment and deprivation effects and the effects of infant separation experiences, epigenetic effects, and the biological embedding of experiences. Translational issues are discussed in relation to the hypothalamic-pituitary-adrenal axis, epigenetics, and inflammation. In conclusion, it is suggested that there are immediate possibilities for experimental medicine but caution is needed with respect to moving into translation too quickly. PMID- 27691979 TI - An investigation of child maltreatment and epigenetic mechanisms of mental and physical health risk. AB - In the present investigation, differential methylation analyses of the whole genome were conducted among a sample of 548 school-aged low-income children (47.8% female, 67.7% Black, M age = 9.40 years), 54.4% of whom had a history of child maltreatment. In the context of a summer research camp, DNA samples via saliva were obtained. Using GenomeStudio, Methylation Module, and the Illumina Custom Model, differential methylation analyses revealed a pattern of greater methylation at low methylation sites (n = 197 sites) and medium methylation sites (n = 730 sites) and less methylation at high methylation sites (n = 907 sites) among maltreated children. The mean difference in methylation between the maltreated and nonmaltreated children was 6.2%. The relative risk of maltreatment with known disease biomarkers was also investigated using GenoGo MetaCore Software. A large number of network objects previously associated with mental health, cancer, cardiovascular systems, and immune functioning were identified evidencing differential methylation among maltreated and nonmaltreated children. Site-specific analyses were also conducted for aldehyde dehydrogenase 2 (ALDH2), ankyrin repeat and kinase domain containing 1 (ANKK1), and nuclear receptor subfamily 3, group C, member 1 (NR3C1) genes, and the results highlight the importance of considering gender and the developmental timing of maltreatment. For ALDH2, the results indicated that maltreated girls evidenced significantly lower methylation compared to nonmaltreated girls, and maltreated boys evidenced significantly higher methylation compared to nonmaltreated boys. Moreover, early onset-not recently maltreated boys evidenced significantly higher methylation at ALDH2 compared to nonmaltreated boys. Similarly, children with early onset nonrecent maltreatment evidenced significantly higher methylation compared to nonmaltreated children at ANKK1. The site-specific results were not altered by controlling for genotypic variation of respective genes. The findings demonstrate increased risk for adverse physical and mental health outcomes associated with differences in methylation in maltreated children and indicate differences among maltreated children related to developmental timing of maltreatment and gender in genes involved in mental health functioning. PMID- 27691982 TI - Epigenetic regulation of cognition: A circumscribed review of the field. AB - The last decade has been marked by an increased interest in relating epigenetic mechanisms to complex human behaviors, although this interest has not been balanced, accentuating various types of affective and primarily ignoring cognitive functioning. Recent animal model data support the view that epigenetic processes play a role in learning and memory consolidation and help transmit acquired memories even across generations. In this review, we provide an overview of various types of epigenetic mechanisms in the brain (DNA methylation, histone modification, and noncoding RNA action) and discuss their impact proximally on gene transcription, protein synthesis, and synaptic plasticity and distally on learning, memory, and other cognitive functions. Of particular importance are observations that neuronal activation regulates the dynamics of the epigenome's functioning under precise timing, with subsequent alterations in the gene expression profile. In turn, epigenetic regulation impacts neuronal action, closing the circle and substantiating the signaling pathways that underlie, at least partially, learning, memory, and other cognitive processes.

PMID- 27691981 TI - Testing the biological embedding hypothesis: Is early life adversity associated with a later proinflammatory phenotype? AB - Accumulating evidence suggests that the experience of early life adversity is a risk factor for a range of poor outcomes across development, including poor physical health in adulthood. The biological embedding model of early adversity (Miller, Chen, & Parker, 2011) suggests that early adversity might become embedded within immune cells known as monocytes/macrophages, programming them to be overly aggressive to environmental stimuli and insensitive to inhibitory signals, creating a "proinflammatory phenotype" that increases vulnerability to chronic diseases across the life span. We tested this hypothesis in the present study. Adolescent girls (n = 147) had blood drawn every 6 months across a 2.5 year period. To assess inflammatory responses to challenge, their monocytes were stimulated in vitro with a bacterial product, and production of the cytokine interleukin-6 was quantified. Hydrocortisone was added to cultures to assess the cells' sensitivity to glucocorticoids' anti-inflammatory signal. Using cluster analyses, we found that early life adversity was associated with greater odds of displaying a proinflammatory phenotype characterized by relatively larger interleukin-6 responses and relatively less sensitivity to glucocorticoids. In contrast, ongoing social stress was not associated with increasing odds of being categorized in the proinflammatory cluster. These findings suggest that early life adversity increases the probability of developing a proinflammatory phenotype, which, if sustained, could forecast risk for health problems later in life.

PMID- 27691986 TI - An Evaluation of Food as a Potential Source for Clostridium difficile Acquisition in Hospitalized Patients. AB - OBJECTIVE To determine whether Clostridium difficile is present in the food of hospitalized patients and to estimate the risk of subsequent colonization associated with C. difficile in food. METHODS This was a prospective cohort study of inpatients at a university-affiliated tertiary care center, May 9, 2011-July 12, 2012. Enrolled patients submitted a portion of food from each meal. Patient stool specimens and/or rectal swabs were collected at enrollment, every 3 days thereafter, and at discharge, and were cultured for C. difficile. Clinical data were reviewed for evidence of infection due to C. difficile. A stochastic, discrete event model was developed to predict exposure to C. difficile from food, and the estimated number of new colonization events from food exposures per 1,000 admissions was determined. RESULTS A total of 149 patients were enrolled and 910 food specimens were obtained. Two food specimens from 2 patients were positive for C. difficile (0.2% of food samples; 1.3% of patients). Neither of the 2 patients was colonized at baseline with C. difficile. Discharge colonization status was available for 1 of the 2 patients and was negative. Neither was diagnosed with C. difficile infection while hospitalized or during the year before or after study enrollment. Stochastic modeling indicated contaminated hospital food would be responsible for less than 1 newly colonized patient per 1,000 hospital admissions. CONCLUSIONS The recovery of C. difficile from the food of hospitalized patients was rare. Modeling suggests hospital food is unlikely to be a source of C. difficile acquisition.

AB - OBJECTIVES: The Medical Services Advisory Committee (MSAC) makes recommendations to the Australian Government for funding health technologies under the Medicare Benefits Schedule (MBS). Differences in public, clinical, commercial, and political opinions on health expenditure emphasize the importance of defensible funding decisions. We aimed to evaluate the quality of health technology assessment (HTA) reports over time and among health technologies assessed for MSAC. MAIN OUTCOME MEASURES: A cohort study was performed of HTA reports prepared for MSAC between 1998 and 2013. We measured the quality of HTA reports using reporting guidelines proposed by the European Collaboration for Assessment of Health Interventions. Individual component scores across eleven domains were calculated, and summed for an overall aggregate score. We used linear regression to investigate any change in quality over time and among the types of technologies assessed. RESULTS: We included 110 HTA reports. The safety (80 percent), effectiveness (84 percent), economic (74 percent), and organizational (99 percent) domains were better reported than the psychological, social, and ethical considerations (34 percent). The basic (75 percent), methodological (62 percent), background (82 percent), contextual (46 percent), status quo (54 percent), and technical information (66 percent) that framed each assessment were inconsistently reported. On average, overall quality scores increased by 2 percent (p < 0.001) per year, from approximately 60 percent to 80 percent over the 15-year period, with no significant difference among surgical, diagnostic or other nonpharmaceutical health technologies (p = 0.22). CONCLUSIONS: HTA reports prepared for MSAC are a key tool in allocating scarce health resources. The overall quality of these reports has improved, but the reporting of specific domains and subthemes therein could be better addressed. PMID- 27691987 TI - Claw disorders in dairy cattle - an unexpected association between energy metabolism and sole haemorrhages. AB - The present study investigated whether changes of energy metabolism post-partum (pp) are associated with claw health. For this purpose, back-fat-thickness (BFT) was measured and blood samples were taken from 146 cows at four examination times. The serum levels of free fatty acids (FFA), beta-hydroxybutyrate (BHB) and glucose were measured. Furthermore, in the first week postpartum (pp) and at 8 weeks pp, a claw trimming was done and the presence and extent of sole haemorrhages (SH) was recorded. Animals with high BFT at calving and therefore high fat mobilisation and whose FFA and BHB levels in the first week pp exceeded the reference values had fewer pathological changes of the claws than thinner animals whose FFA and BHB levels stayed within reference ranges. The body condition before calving, represented in this study by BFT, plays an important role in non-infectious claw disorders. Poorer body condition was found to be associated with the SH that develop in the first 2 months of lactation. PMID- 27691985 TI - Childhood adversity and epigenetic regulation of glucocorticoid signaling genes: Associations in children and adults. AB - Early childhood experiences have lasting effects on development, including the risk for psychiatric disorders. Research examining the biologic underpinnings of these associations has revealed the impact of childhood maltreatment on the physiologic stress response and activity of the hypothalamus-pituitary-adrenal axis. A growing body of literature supports the hypothesis that environmental exposures mediate their biological effects via epigenetic mechanisms. Methylation, which is thought to be the most stable form of epigenetic change, is a likely mechanism by which early life exposures have lasting effects. We present recent evidence related to epigenetic regulation of genes involved in hypothalamus-pituitary-adrenal axis regulation, namely, the glucocorticoid receptor gene (nuclear receptor subfamily 3, group C, member 1 [NR3C1]) and FK506 binding protein 51 gene (FKBP5), after childhood adversity and associations with risk for psychiatric disorders. Implications for the development of interventions and future research are discussed. PMID- 27691990 TI - TESTING MULTI-CRITERIA DECISION ANALYSIS FOR MORE TRANSPARENT RESOURCE-ALLOCATION DECISION MAKING IN COLOMBIA. AB - OBJECTIVES: In 2012, Colombia experienced an important institutional transformation after the establishment of the Health Technology Assessment Institute (IETS), the disbandment of the Regulatory Commission for Health and the reassignment of reimbursement decision-making powers to the Ministry of Health and Social Protection (MoHSP). These dynamic changes provided the opportunity to test Multi-Criteria Decision Analysis (MCDA) for systematic and more transparent resource-allocation decision-making. METHODS: During 2012 and 2013, the MCDA framework Evidence and Value: Impact on Decision Making (EVIDEM) was tested in Colombia. This consisted of a preparatory stage in which the investigators conducted literature searches and produced HTA reports for four interventions of interest, followed by a panel session with decision makers. This method was contrasted with a current approach used in Colombia for updating the publicly financed benefits package (POS), where narrative health technology assessment (HTA) reports are presented alongside comprehensive budget impact analyses (BIAs). RESULTS: Disease severity, size of population, and efficacy ranked at the top among fifteen preselected relevant criteria. MCDA estimates of technologies of interest ranged between 71 to 90 percent of maximum value. The ranking of technologies was sensitive to the methods used. Participants considered that a two-step approach including an MCDA template, complemented by a detailed BIA would be the best approach to assist decision-making in this context. Participants agreed that systematic priority setting should take place in Colombia. CONCLUSIONS: This work may serve as the basis to the MoHSP on its interest of setting up a systematic and more transparent process for resource allocation decision-making. PMID- 27691989 TI - Comparison of Data Collection for Healthcare-Associated Infection Surveillance in Nursing Homes. AB - OBJECTIVE To facilitate surveillance and describe the burden of healthcare associated infection (HAI) in nursing homes (NHs), we compared the quality of resident-level data collected by NH personnel and external staff. DESIGN A 1-day point-prevalence survey SETTING AND PARTICIPANTS Overall, 9 nursing homes among 4 Centers for Disease Control and Prevention (CDC) Emerging Infection Program (EIP) sites were included in this study. METHODS NH personnel collected data on resident characteristics, clinical risk factors for HAIs, and the presence of 3 HAI screening criteria on the day of the survey. Trained EIP surveillance officers collected the same data elements via retrospective medical chart review for comparison; surveillance officers also collected available data to identify HAIs (using revised McGeer definitions). Overall agreement was calculated among residents identified by both teams with selected risk factors and HAI screening criteria. The impact of using NH personnel to collect screening criteria on HAI prevalence was assessed. RESULTS The overall prevalence of clinical risk factors among the 1,272 residents was similar between NH personnel and surveillance officers, but the level of positive agreement (residents with factors identified by both teams) varied between 39% and 87%. Surveillance officers identified 253 residents (20%) with >=1 HAI screening criterion, resulting in 67 residents with an HAI (5.3 per 100 residents). The NH personnel identified 152 (12%) residents with >=1 HAI screening criterion; 42 residents had an HAI (3.5 per 100 residents). CONCLUSION We identified discrepancies in resident-level data collection between surveillance officers and NH personnel, resulting in varied estimates of the HAI prevalence. These findings have important implications for the design and implementation of future HAI prevalence surveys. Infect Control Hosp Epidemiol 2016;1440-1445. PMID- 27691991 TI - Haplotypic variation in the UCP1 gene is associated with milk traits in dairy cows. AB - Uncoupling protein-1 (UCP1) plays a role in the regulation of body temperature, metabolic rate and energy expenditure in animals. While variation in UCP1 and its phenotypic effect has been investigated in humans and sheep, little is known about this gene in cattle. In this study, four regions of bovine UCP1 were investigated in 612 Holstein-Friesian * Jersey (HF * J) dairy cows using polymerase chain reaction-single stranded conformational polymorphism (PCR-SSCP) analyses. In the four regions of the gene analysed, a total of 13 SNPs were detected. Three sequences (a, b and c) were found in Region-2 and three sequences (A, B and C) were found in Region-4, and these were assembled into three (a-B, b B and c-A) common and three (b-C, c-B and c-C) rare haplotypes. Of the three common haplotypes, b-B and c-A were associated (P < 0.007 and P < 0.043, respectively) with increased milk yield and tended to be associated (P < 0.085 and P < 0.070, respectively) with decreased fat percentage. Cows with genotype b B/a-B produced more milk (P < 0.004), but with a lower percentage of fat (P < 0.035) and protein (P < 0.038) than cows with genotype a-B/a-B. Cows of genotype a-B/c-A had milk of low fat percentage (P < 0.017), but tended to produce more milk (P < 0.059) than cows of genotype a-B/a-B. This suggests that UCP1 affects milk yield, milk fat percentage and milk protein percentage. PMID- 27691992 TI - EARLY COST-EFFECTIVENESS ANALYSIS OF NEW MEDICAL TESTS: RESPONSE. AB - As strong advocates and adopters of early cost-effectiveness modeling for test evaluation, we were excited to see the recent article "The Early Bird Catches the Worm: Early Cost-Effectiveness Analysis of New Medical Tests," in which Buisman and colleagues present a succinct and generalizable framework for conducting this type of analysis. The authors have done an excellent job in identifying and summarizing the key components of this methodology, as well as highlighting fundamental differences between early analyses versus the traditional late-stage approach. As the number of medical tests coming to market continues to grow, there is an ever growing need to develop rigorous methodology in this area, and we commend the authors for this timely work. PMID- 27691993 TI - EMERGENCE OF "DRIVERS" FOR THE IMPLEMENTATION OF HEALTH TECHNOLOGY ASSESSMENT. AB - BACKGROUND: Health technology assessment (HTA) examines the consequences of the application of health technologies and is aimed at better informing decision makers. Over the past 30 years, different countries have implemented HTA organizations. Colombia established by law its own HTA agency (IETS) in 2011 which started operations in November 2012. The aim of this study was to assess the feasibility of conducting and using HTA to inform decision-making in this context. Through a qualitative approach, ten "drivers" emerged with the ability to help or hinder HTA development in this context: availability and quality of data, implementation strategy, cultural aspects, local capacity, financial support, policy/political support, globalization, stakeholder pressure, health system context, and usefulness perception. METHODS: Semi-structured interviews were conducted with key HTA researchers, after following rigorous transcription, and thematic content analysis, those aspects that may be barriers or facilitator for HTA development and use in Colombia were identified. RESULTS: Although HTA has become a tool to inform decision-making around the world, its use may vary according to setting. Determining those aspects which may enable or interfere with HTA development and use in Colombia may be useful for other countries when considering the establishment of HTA systems. CONCLUSIONS: The conceptual transferability of concepts like "drivers" with caveats may be of interest for similar settings trying to incorporate HTA processes and institutions into systematic decision-making.

AB - This article explores the factors determining whether older adults engage in the Senior Games and related leisure-time physical activity through examining the adults' salient beliefs. We conducted 10 in-depth interviews with older adults who have participated in the Senior Games. Underpinned by the planned behavior theory's framework, we explored three types of beliefs: advantages and disadvantages (behavioral beliefs), social support and pressure (normative beliefs), and facilitators and impediments (control beliefs). Interview respondents were found to engage in the Senior Games and related physical activity to the extent that they associated various intangible advantages with the games and valued psychological satisfaction. They viewed their peers and families as supporting and approving of their engagement and recognized the physical capabilities required, and structural constraints necessary, to engage in the games and related activity. With these findings, pertinent beliefs can be combined with interventions designed to encourage leisure-time physical activities by older adults. PMID- 27691996 TI - Variation of milk coagulation properties, cheese yield, and nutrients recovery in curd of cows of different breeds before, during and after transhumance to highland summer pastures. AB - This paper aimed at evaluating the effect of summer transhumance to mountain pastures of dairy cows of different breeds on cheese-making ability of milk. Data were from 649 dairy cows of specialized (Holstein Friesian and Brown Swiss) dual purpose (Simmental) and local (mostly Rendena and Alpine Grey) breeds. The Fourier-Transform Infra-Red Spectra (FTIRS) of their milk samples were collected before and after transhumance in 109 permanent dairy farms, and during transhumance in 14 summer farms (with multi-breeds herds) of the Trento Province, north-eastern Italy. A variety of 18 traits describing milk coagulation, curd firming, cheese yield and nutrients recovery in curd/loss in whey were predicted on the basis of FTIRS collected at the individual cow level. Moving the cows to summer farms improved curd firming traits but reduced cheese yields because of an increase of water and fat lost in the whey. During summer grazing, most of cheese making traits improved, often non-linearly. The milk from summer farms supplementing cows with more concentrates showed better curd firming and cheese yield, because of lower fat lost in the whey. The breed of cows affected almost all the traits with a worst cheese-making ability for milk samples of Holsteins through all the trial, and interacted with concentrate supplementation because increasing compound feed tended to improve cheese-making traits for all breed, with the exception of local breeds for coagulation time and of Brown Swiss for curd firming time. In general, summer transhumance caused a favourable effect on cheese-making aptitude of milk, even though with some difference according to parity, initial days in milk, breed and concentrate supplementation of cows. PMID- 27691995 TI - The presence of fever in adults with influenza and other viral respiratory infections. AB - We compared the rates of fever in adult subjects with laboratory-confirmed influenza and other respiratory viruses and examined the factors that predict fever in adults. Symptom data on 158 healthcare workers (HCWs) with a laboratory confirmed respiratory virus infection were collected using standardized data collection forms from three separate studies. Overall, the rate of fever in confirmed viral respiratory infections in adult HCWs was 23.4% (37/158). Rates varied by virus: human rhinovirus (25.3%, 19/75), influenza A virus (30%, 3/10), coronavirus (28.6%, 2/7), human metapneumovirus (28.6%, 2/7), respiratory syncytial virus (14.3%, 4/28) and parainfluenza virus (8.3%, 1/12). Smoking [relative risk (RR) 4.65, 95% confidence interval (CI) 1.33-16.25] and co infection with two or more viruses (RR 4.19, 95% CI 1.21-14.52) were significant predictors of fever. Fever is less common in adults with confirmed viral respiratory infections, including influenza, than described in children. More than 75% of adults with a viral respiratory infection do not have fever, which is an important finding for clinical triage of adult patients with respiratory infections. The accepted definition of 'influenza-like illness' includes fever and may be insensitive for surveillance when high case-finding is required. A more sensitive case definition could be used to identify adult cases, particularly in event of an emerging viral infection. PMID- 27691997 TI - Reproductive efficiency of the bethylid wasp Cephalonomia tarsalis: the influences of spatial structure and host density. AB - The parasitoid wasp Cephalonomia tarsalis (Ashmead) (Hymenoptera: Bethylidae) is commonly present in stored product facilities. While beneficial, it does not provide a high degree of biological pest control against its host, the saw toothed beetle Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae). A candidate explanation for poor host population suppression is that adult females interfere with each other's foraging and reproductive behavior. We used simple laboratory microcosms to evaluate such mutual interference in terms of its overall effects on offspring production. We varied the density of the hosts and also the spatial structure of the environment, via the extent of population sub division and the provision of different substrates. Production of C. tarsalis offspring was positively influenced by host density and by the isolation of females. With incomplete sub-division within microcosms offspring production was, in contrast, low and even zero. The provision of corrugated paper as a substrate enhanced offspring production and partially mitigated the effects of mutual interference. We recommend simple improvements to mass rearing practice and identify promising areas for further behavioral and chemical studies towards a better understanding of the mechanisms of mutual interference. PMID- 27691999 TI - Control of oxidation-reduction potential during Cheddar cheese ripening and its effect on the production of volatile flavour compounds. AB - In cheese, a negative oxidation-reduction (redox) potential is required for the stability of aroma, especially that associated with volatile sulphur compounds. To control the redox potential during ripening, redox agents were added to the salted curd of Cheddar cheese before pressing. The control cheese contained only salt, while different oxidising or reducing agents were added with the NaCl to the experimental cheeses. KIO3 (at 0.05, 0.1 and 1%, w/w) was used as the oxidising agent while cysteine (at 2%, w/w) and Na2S2O4 (at 0.05 and 0.1%, w/w) were used as reducing agents. During ripening the redox potential of the cheeses made with the reducing agents did not differ significantly from the control cheese (E h ~ -120 mV) while the cheeses made with 0.1 and 0.05% KIO3 had a significantly higher and positive redox potential in the first month of ripening. Cheese made with 1% KIO3 had positive values of redox potential throughout ripening but no starter lactic acid bacteria survived in this cheese; however, numbers of starter organisms in all other cheeses were similar. Principal component analysis (PCA) of the volatile compounds clearly separated the cheeses made with the reducing agents from cheeses made with the oxidising agents at 2 month of ripening. Cheeses with reducing agents were characterized by the presence of sulphur compounds whereas cheeses made with KIO3 were characterized mainly by aldehydes. At 6 month of ripening, separation by PCA was less evident. These findings support the hypothesis that redox potential could be controlled during ripening and that this parameter has an influence on the development of cheese flavour. PMID- 27691998 TI - Characterisation of equine satellite cell transcriptomic profile response to beta hydroxy-beta-methylbutyrate (HMB). AB - beta-Hydroxy-beta-methylbutyrate (HMB) is a popular ergogenic aid used by human athletes and as a supplement to sport horses, because of its ability to aid muscle recovery, improve performance and body composition. Recent findings suggest that HMB may stimulate satellite cells and affect expressions of genes regulating skeletal muscle cell growth. Despite the scientific data showing benefits of HMB supplementation in horses, no previous study has explained the mechanism of action of HMB in this species. The aim of this study was to reveal the molecular background of HMB action on equine skeletal muscle by investigating the transcriptomic profile changes induced by HMB in equine satellite cells in vitro. Upon isolation from the semitendinosus muscle, equine satellite cells were cultured until the 2nd day of differentiation. Differentiating cells were incubated with HMB for 24 h. Total cellular RNA was isolated, amplified, labelled and hybridised to microarray slides. Microarray data validation was performed with real-time quantitative PCR. HMB induced differential expressions of 361 genes. Functional analysis revealed that the main biological processes influenced by HMB in equine satellite cells were related to muscle organ development, protein metabolism, energy homoeostasis and lipid metabolism. In conclusion, this study demonstrated for the first time that HMB has the potential to influence equine satellite cells by controlling global gene expression. Genes and biological processes targeted by HMB in equine satellite cells may support HMB utility in improving growth and regeneration of equine skeletal muscle; however, the overall role of HMB in horses remains equivocal and requires further proteomic, biochemical and pharmacokinetic studies. PMID- 27692001 TI - Acetoacetic acid induces oxidative stress to inhibit the assembly of very low density lipoprotein in bovine hepatocytes. AB - Dairy cows with fatty liver or ketosis exhibit hyperketonemia, oxidative stress, and a low rate of very low density lipoprotein (VLDL) assembly, and there may be a potential link among these characteristics. Therefore, the objective of this study was to determine the effect of acetoacetic acid (AcAc) on the assembly of VLDL in cow hepatocytes. Cultured cow hepatocytes were treated with different concentrations of AcAc with or without N-acetylcysteine (NAC, an antioxidant). AcAc treatment decreased the mRNA expression and activities of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px), and significantly increased malondialdehyde (MDA) content, indicative of oxidative stress. Furthermore, AcAc treatment significantly down-regulated the mRNA expression of apolipoprotein B100 (ApoB100), apolipoprotein E (ApoE), and low density lipoprotein receptor (LDLR), which thus decreased VLDL assembly and increased triglyceride (TG) accumulation in these bovine hepatocytes. Importantly, NAC relieved AcAc-induced oxidative stress and increased VLDL assembly. In summary, these results suggest that AcAc-induced oxidative stress affects the assembly of VLDL, which increases TG accumulation in bovine hepatocytes. PMID- 27692000 TI - Frequency of autoimmune disorders and autoantibodies in patients with neuromyelitis optica. AB - OBJECTIVE: The aim of this study was to report the frequency of autoimmune disorders and autoantibodies in 22 patients with neuromyelitis optica (NMO), as well as whether the seropositivity for autoantibodies differs between anti aquaporin 4 (AQP4) positive and AQP4 negative NMO patients. METHODS: Demographic, medical records, and a profile of autoantibodies were evaluated in 22 NMO patients, including AQP4, anti-thyroid-stimulating hormone receptor, antinuclear antibodies (ANA), anti-thyroperoxidase (anti-TPO), anti-thyroglobulin (anti-Tg), anti-double-stranded DNA, anti-neutrophil cytoplasmic, anti-cyclic citrullinate peptide, rheumatoid factor, anti-SSA/Ro, anti-SSB/La, anti-Smith antibodies (anti Sm), anti-ribonucleoprotein, anti-nucleosome, and anti-Scl70. Thyroid-stimulating hormone and free thyroxin were measured. RESULTS: The frequency of women was higher than men (95.5% vs. 4.5%) and 68.2% were Afro-Brazilians. Six (27.3%) patients presented other autoimmune disorders, such as Hashimoto thyroiditis (n=2), Graves' disease (n=1), juvenile idiopathic arthritis (n=1), systemic lupus erythematosus and systemic sclerosis (n=1), and Raynaud's phenomenon (n=1). The most frequent autoantibodies were anti-AQP4 (54.5%), anti-nucleosome (31.8%), ANA (27.3%), anti-TPO (22.7%), and anti-Tg (22.7%). Difference was not observed in the frequency of autoimmune disorders when the patients were compared according to their anti-AQP4 status. CONCLUSION: The results of the present study underscored that the NMO patients present high frequency of autoantibodies against cellular antigens and the presence of autoimmune disorders. Further studies with large number of NMO patients may contribute to advances in the understanding of NMO disease mechanisms. PMID- 27692002 TI - SURVEY OF SEXUAL ACTIVITY AND CONTRACEPTIVE USE AMONG UNMARRIED YOUNG SCHOOL AND COLLEGE DROP-OUTS IN A DEFINED NIGERIAN POPULATION. AB - This study sought to characterize sexual behaviour, contraceptive use and contributory upbringing factors among young people who had dropped out of school or college in a Nigerian setting. A community-based, cross-sectional sexual survey of 161 young people aged between 15 and 35 who had dropped out of school or college was performed in Ado-Ekiti, south-west Nigeria, in April 2015. One hundred and nineteen of the respondents (73.9%) had had sexual intercourse. Mean age at sexual debut was 19.08+/-3.5 years. Of those with sexual experience, 79 (66.4%) had their sexual debut with a previous boy/girlfriend and 33 (27.7%) had it in their current relationship. Three (2.5%) respondents had first sex with a stranger. About 90% were still having sexual intercourse within 12 months of the survey; more males had had sex than females (81.1% versus 67.8%). Around 80% of those with sexual exposure practised a form of contraception, mainly use of the male condom, but fewer than 25% were all-time contraceptive users. Coming from a single-parent family (p=0.04) or from a family of poor economic status (AOR: 7.41; 95% CI: 0.69-0.83) were found to be associated with sexual debut by the age of 19 and premarital sex, respectively, in these young people. Unprotected sexual intimacy was found to be high among young school/college drop-outs in this region of Nigeria. This group of young people need targeted reproductive health intervention as they represent a potent route for HIV transmission in the region. PMID- 27692003 TI - REPRODUCTIVE AND CHILD HEALTH SERVICES AND DEMOGRAPHIC CHANGE IN THE DISTRICTS OF UTTAR PRADESH, 2002-13. AB - This study examined the effect of reproductive and child health (RCH) services on fertility and child mortality in the districts of Uttar Pradesh. It specifically measured the effect of antenatal care, medical assistance at birth, child immunization and use of modern methods of contraception on Total Fertility Rate (TFR), Infant Mortality Rate (IMR) and Under-five Morality Rate (U5MR) before and after the National Rural Health Mission (NRHM) period. Data from the 2002-04 District Level Household Survey (DLHS-2), 2012-13 Annual Health Survey (AHS) and the 2001 and 2011 Censuses of India were used. The TFR and U5MR were estimated from the Census of India with district as the unit of analysis. Descriptive statistics, composite indices, random- and fixed-effects models and difference-in difference models were used to understand the effect of RCH services on the reduction in TFR, IMR and the U5MR. The results suggest large inter-district variations in the coverage of RCH services in the state. During the post-NRHM period, improvement was highest in safe delivery followed by immunization coverage and antenatal care and least for contraceptive use in most districts. The relative ranking of districts has not changed much over time. In 2002-04, the RCH Index was highest in Lucknow (0.442) followed by Ballia and least in Kaushambi (0.115). By 2012-13, it was highest in Jhansi (0.741) and lowest in Shrawasti (0.241). The districts of Kaushambi, Unnao, Mahoba, Banda and Hardoi performed better in the RCH Index over time, while Ballia, Gautam Buddha Nagar, Kanpur Nagar, Pratapgarh and Sonbhadra remained poor. The RCH service coverage and demographic outcomes were poor in seven districts, particularly those in eastern and western Uttar Pradesh. The regression analyses suggest that the RCH Index exerts greater influence on the reduction in IMR and U5MR, while female literacy exerts greater influence on the reduction in TFR. The results of the hybrid model suggest that a 10% change in RCH Index would lead to a 3 point decline in IMR, and a 10% increase in female literacy would lead to a 0.2 point decline in TFR. The study suggests continuing investment in female education and RCH services with a greater focus on poor-performing districts to realize demographic and health targets. PMID- 27692004 TI - Inflammatory aspects of epileptogenesis: contribution of molecular inflammatory mechanisms. AB - OBJECTIVE: Epilepsy is a chronic neurological disease characterised with seizures. The aetiology of the most generalised epilepsies cannot be explicitly determined and the seizures are pronounced to be genetically determined by disturbances of receptors in central nervous system. Besides, neurotransmitter distributions or other metabolic problems are supposed to involve in epileptogenesis. Lack of adequate data about pharmacological agents that have antiepileptogenic effects point to need of research on this field. Thus, in this review, inflammatory aspects of epileptogenesis has been focussed via considering several concepts like role of immune system, blood-brain barrier and antibody involvement in epileptogenesis. METHODS: We conducted an evidence-based review of the literatures in order to evaluate the possible participation of inflammatory processes to epileptogenesis and also, promising agents which are effective to these processes. We searched PubMed database up to November 2015 with no date restrictions. RESULTS: In the present review, 163 appropriate articles were included. Obtained data suggests that inflammatory processes participate to epileptogenesis in several ways like affecting fibroblast growth factor-2 and tropomyosin receptor kinase B signalling pathways, detrimental proinflammatory pathways [such as the interleukin-1 beta (IL-1beta)-interleukin-1 receptor type 1 (IL-1R1) system], mammalian target of rapamycin pathway, microglial activities, release of glial inflammatory proteins (such as macrophage inflammatory protein, interleukin 6, C-C motif ligand 2 and IL-1beta), adhesion molecules that are suggested to function in signalling pathways between neurons and microglia and also linkage between these molecules and proinflammatory cytokines. CONCLUSION: The literature research indicated that inflammation is a part of epileptogenesis. For this reason, further studies are necessary for assessing agents that will be effective in clinical use for therapeutic treatment of epileptogenesis. PMID- 27692005 TI - Impact of an Infection Control and Antimicrobial Stewardship Program on Solid Organ Transplantation and Hepatobiliary Surgical Site Infections. AB - OBJECTIVE The goal of this long-term quasi-experimental retrospective study was to assess the impact of a 5-year serial infection control and antimicrobial stewardship intervention on surgical site infections (SSIs). METHODS This study was conducted in a tertiary-care public teaching institution over a 5-year period from January 2010 to December 2014. All patients undergoing hepatobiliary surgery and liver, kidney, pancreas, and simultaneous pancreas-kidney transplantation were included. Outcomes were compared between a preintervention group (2010-2011) and a postintervention group (2012-2014). RESULTS A total of 1,424 procedures averaged an overall SSI rate of 11.2%. After implementation of the interventions, a decrease of 52.8% in SSI rates from 17.4% to 8.2% was observed (P50% (relative rate; P<.001) was observed in superficial incisional and organ-space infections between pre- and postintervention groups. In addition, a 54.9% decrease from 19.7% to 8.9% (P<.001; OR, 2.2; 95% CI, 1.4-3.5) and a 51.6% decrease from 15.5% to 7.5% (P=.001; OR, 2.2; 95% CI, 1.4-3.5) were observed for SSI rates in hepatobiliary surgery and solid organ transplantation, respectively. The antimicrobial stewardship intervention increased overall conformity to the internal surgical prophylaxis protocol by 15.2% (absolute rate) from 45.1% to 60.3% (P<.003; 95% CI, 5.4-24.9). CONCLUSIONS A long-term serial infection control and antimicrobial stewardship intervention decreased SSIs among patients undergoing hepatobiliary surgery and liver, kidney, pancreas, and simultaneous pancreas-kidney transplantation.

PMID- 27692006 TI - PERCEPTIONS OF STIGMA AND DISCRIMINATION IN HEALTH CARE SETTINGS TOWARDS SUB SAHARAN AFRICAN MIGRANT WOMEN LIVING WITH HIV/AIDS IN BELGIUM: A QUALITATIVE STUDY. AB - Stigma and discrimination within health care settings remain a public health challenge across diverse cultural environments and may have deleterious effects on mental and physical health. This study explores the causes, forms and consequences of HIV-related stigma and discrimination among migrant sub-Saharan African women living with HIV in Belgium. A qualitative study was conducted with 44 HIV-positive sub-Saharan African migrant women between April 2013 and December 2014 in health care settings in Belgium. Data were analysed using thematic content analysis. Twenty-five of the women reported overt stigma and discrimination and fifteen reported witnessing behaviours that they perceived to be stigmatizing and discriminatory in health care settings. The themes that emerged as to the causes of stigma and discrimination were: public perceptions of migrants and HIV, fear of contamination and institutional policies on HIV management. Reported forms of stigma and discrimination included: delayed or denied care, excessive precautions, blame and humiliation. The consequences of stigma and discrimination were: emotional stress, inconsistent health-care seeking behaviour and non-disclosure to non-HIV treating personnel. Stigma and discrimination in health care settings towards people with HIV, and more specifically towards HIV-positive sub-Saharan African migrant women, impedes sustainable preventive measures. Specialized education and training programmes for non-HIV health care providers require in-depth investigation. PMID- 27692008 TI - MATERNAL HEIGHT AND PRE-PREGNANCY WEIGHT STATUS ARE ASSOCIATED WITH FETAL GROWTH PATTERNS AND NEWBORN SIZE. AB - The impact of maternal height, pre-pregnancy weight status and gestational weight gain on fetal growth patterns and newborn size was analysed using a dataset of 4261 singleton term births taking place at the Viennese Danube Hospital between 2005 and 2013. Fetal growth patterns were reconstructed from three ultrasound examinations carried out at the 11th/12th, 20th/21th and 32th/33th weeks of gestation. Crown-rump length, biparietal diameter, fronto-occipital diameter, head circumference, abdominal transverse diameter, abdominal anterior-posterior diameter, abdominal circumference and femur length were determined. Birth weight, birth length and head circumference were measured immediately after birth. The vast majority of newborns were of normal weight, i.e. between 2500 and 4000 g. Maternal height showed a just-significant but weak positive association (r=0.03: p=0.039) with crown-rump length at the first trimester and with the majority of fetal parameters at the second trimester (r>0.06; p0.09; p0.08; p0.17; p0.13; p0.13; p<0.001), were significantly positively associated with newborn size. Some of these associations were quite weak and the statistical significance was mainly due to the large sample size. The association patterns between maternal height and pre-pregnancy weight status with fetal growth patterns (p<0.001), as well as newborn size (p<0.001), were independent of maternal age, nicotine consumption and fetal sex. In general, taller and heavier women gave birth to larger infants. This association between maternal size and fetal growth patterns was detectable from the first trimester onwards. PMID- 27692007 TI - Resilience to adversity and the early origins of disease. AB - For the past quarter century, scientists at the Center for Family Research at the University of Georgia have conducted research designed to promote understanding of normative developmental trajectories among low socioeconomic status African American children, youths, and young adults. In this paper, we describe a recent expansion of this research program using longitudinal, epidemiological studies and randomized prevention trials to test hypotheses about the origins of disease among rural African American youths. The contributions of economic hardship, downward mobility, neighborhood poverty, and racial discrimination to allostatic load and epigenetic aging are illustrated. The health benefits of supportive family relationships in protecting youths from these challenges are also illustrated. A cautionary set of studies is presented showing that some psychosocially resilient youths demonstrate high allostatic loads and accelerated epigenetic aging, suggesting that, for some, "resilience is just skin deep." Finally, we end on an optimistic note by demonstrating that family-centered prevention programs can have health benefits by reducing inflammation, helping to preserve telomere length, and inhibiting epigenetic aging. PMID- 27692010 TI - Exploring a post-traumatic stress disorder paradigm in Flinders sensitive line rats to model treatment-resistant depression II: response to antidepressant augmentation strategies. AB - OBJECTIVE: Post-traumatic stress disorder (PTSD) displays high co-morbidity with major depression and treatment-resistant depression (TRD). Earlier work demonstrated exaggerated depressive-like symptoms in a gene*environment model of TRD and an abrogated response to imipramine. We extended the investigation by studying the behavioural and monoaminergic response to multiple antidepressants, viz. venlafaxine and ketamine with/without imipramine. METHODS: Male Flinders sensitive line (FSL) rats, a genetic model of depression, were exposed to a time dependent sensitisation (TDS) model of PTSD and compared with stress naive controls. 7 days after the TDS procedures, immobility and coping (swimming and climbing), behaviours in the forced swim test (FST) as well as hippocampal and cortical 5-hydroxyindoleacetic acid (5HIAA) and noradrenaline (NA) levels were analysed. Response to imipramine, venlafaxine and ketamine treatment (all 10 mg/kg*7 days) alone and in combination were subsequently studied. RESULTS: TDS exacerbated depressive-like behaviour of FSL rats in the FST. Imipramine, venlafaxine and ketamine were ineffective as monotherapy in TDS-exposed FSL rats. However, combining imipramine with either venlafaxine or ketamine resulted in significant anti-immobility effects and enhanced coping behaviours. Only ketamine+imipramine (frontal-cortical 5HIAA and NA), ketamine alone (frontal cortical and hippocampal NA) and venlafaxine+imipramine (frontal-cortical NA) altered monoamine responses versus untreated TDS-exposed FSL rats. CONCLUSION: Exposure of FSL rats to TDS inhibits antidepressant response at behavioural and neurochemical levels. Congruent with TRD, imipramine plus venlafaxine or ketamine overcame treatment resistance in these animals. These data further support the hypothesis that exposure of FSL rats to a PTSD-like paradigm produces a valid animal model of TRD and warrants further investigation. PMID- 27692009 TI - Exploring genetic moderators and epigenetic mediators of contextual and family effects: From Gene * Environment to epigenetics. AB - In the current manuscript, we provide an overview of a research program at the University of Georgia's Center for Family Research designed to expand upon rapid and ongoing developments in the fields of genetics and epigenetics. By placing those developments in the context of translational research on family and community determinants of health and well-being among rural African Americans, we hope to identify novel, modifiable environments and biological processes. In the first section of the article, we review our earlier work on genotypic variation effects on the association between family context and mental and physical health outcomes as well as differential responses to family-based intervention. We then transition to discuss our more recent research on the association of family and community environments with epigenetic processes. In this second section of the article, we begin by briefly reviewing terminology and basic considerations before describing evidence that early environments may influence epigenetic motifs that potentially serve as mediators of long-term effects of early family and community environments on longer term health outcomes. We also provide evidence that genotype may sometimes influence epigenetic outcomes. Finally, we describe our recent efforts to use genome-wide characterization of epigenetic patterns to better understand the biological impact of protective parenting on long-term shifts in inflammatory processes and its potential implications for young adult health. As will be clear, research on epigenetics as a mediator of the connections between family/community processes and a range of health outcomes is still in its infancy, but the potential to develop important insights regarding mechanisms linking modifiable environments to biological processes and long-term health outcomes already is coming into view. PMID- 27692011 TI - Work-to-Family Enrichment and Conflict Profiles: Job Characteristics and Employees' Well-Being. AB - This article aims to analyze work-to-family conflict (WFC) and enrichment (WFE) profiles related to job characteristics and well-being at work and general well being. A cross-sectional survey data of 1885 employees was analyzed. The Latent Profile Analysis revealed that the five-profile solution exhibited strong statistical significance (p > .001). ANCOVAs were performed to analyze the relationship of the identified profiles with job characteristics and well-being. Employees in the Beneficial profile had the best perception of job characteristics (lowest demands and the highest control and support) and the highest well-being, and those in the Harmful profile had the lowest job characteristics perceptions and the lowest well-being. Through a comparison of the Moderate Active profile and the Moderate Harmful profile, WFE was found to buffer the effects of the WFC on well-being at work (burnout; engagement) and on general well-being (i.e., health perceptions). The promotion of WFE through higher job autonomy, job support, and fewer demands is a crucial aspect to consider. This study helps to consolidate the work-family balance typology and its effects on employees' well-being, and broadens this framework to consider job characteristics. PMID- 27692012 TI - How to support teenagers who are losing a parent to cancer: Bereaved young adults' advice to healthcare professionals-A nationwide survey. AB - OBJECTIVE: The loss of a parent to cancer is considered one of the most traumatic events a teenager can experience. Studies have shown that teenagers, from the time of diagnosis, are already extremely worried about the consequences of a parent's cancer but tend to be left to manage these concerns on their own. The present study aimed to explore young adults' advice to healthcare professionals on how to support teenagers who are losing a parent to cancer. METHODS: This work derives from a Swedish nationwide survey and employs a qualitative approach with a descriptive/interpretive design to obtain answers to an open-ended question concerning advice to healthcare professionals. Of the 851 eligible young adults who had lost a parent to cancer when they were 13-16 years of age within the previous 6 to 9 years, 622 participated in our survey (response rate = 73%). Of these 622 young adults, 481 responded to the open-ended question about what advice to give healthcare professionals. RESULTS: Four themes emerged: (1) to be seen and acknowledged; (2) to understand and prepare for illness, treatment, and the impending death; (3) to spend time with the ill parent, and (4) to receive support tailored to the individual teenager's needs. SIGNIFICANCE OF RESULTS: This nationwide study contributes hands-on suggestions to healthcare staff regarding attitudes, communication, and support from the perspective of young adults who, in their teenage years, lost a parent to cancer. Teenagers may feel better supported during a parent's illness if healthcare professionals take this manageable advice forward into practice and see each teenager as individuals; explain the disease, its treatments, and consequences; encourage teenagers to spend time with their ill parent; and recommend sources of support. PMID- 27692013 TI - A comparative study of patient characteristics, opinions, and outcomes, for patients who leave the emergency department before medical assessment. AB - OBJECTIVE: The emergency department (ED) left-without-being-seen (LWBS) rate is a performance indicator, although there is limited knowledge about why people leave, or whether they seek alternate care. We studied characteristics of ED LWBS patients to determine factors associated with LWBS. METHODS: We collected demographic data on LWBS patients at two urban hospitals. Sequential LWBS patients were contacted and surveyed using a standardized telephone survey. A matched group of patients who did not leave were also surveyed. Data were analysed using the Fisher exact test, chi-square test, and student t-test. RESULTS: The LWBS group (n=1508) and control group (n=1504) were matched for sex, triage category, recorded wait times, employment and education, and having a family physician. LWBS patients were younger, more likely to present in the evening or at night, and lived closer to the hospital. A long wait time was the most cited reason for leaving (79%); concern about medical condition was the most common reason for staying (96%). Top responses for improved likelihood of waiting were shorter wait times (LWBS, 66%; control, 31%) and more information on wait times (41%; 23%). A majority in both groups felt that their condition was a true emergency (63%; 72%). LWBS patients were more likely to seek further health care (63% v. 28%; p<0.001) and sooner (median time 1 day v. 2-4 days; p=0.002). Among patients who felt that their condition was not a true emergency, the top reason for ED attendance was the inability to see their family doctor (62% in both groups). CONCLUSION: LWBS patients had similar opinions, experiences, and expectations as control patients. The main reason for LWBS was waiting longer than expected. LWBS patients were more likely to seek further health care, and did so sooner. Patients wait because of concern about their health problem. Shorter wait times and improved communication may reduce the LWBS rate.

AB - Bull beef production is traditionally based on high concentrate rations fed indoors. Inclusion of grazed grass, which is generally a cheaper feed, would decrease the cost of bull beef production, but may affect beef quality. Accordingly, the organoleptic quality and composition of beef from continental sired suckler bulls (n=126) assigned to either ad libitum concentrates to slaughter (C), grass silage (GS) ad libitum for 120 days followed by C (GSC) or GS followed by 100 days at pasture and then C (GSPC) and slaughtered at target carcass weights (CW) of 360, 410 or 460 kg was examined. Tenderness, flavour liking and overall liking were lower (P<0.05) for GSPC than for C and GSC. Intramuscular fat content and soluble collagen proportion were lower (P<0.05) for GSPC than GSC which was lower (P<0.05) than C. Soluble collagen proportion was lower (P<0.05) for 460 kg than 410 kg CW, which was lower (P<0.05) than 360 kg CW. Inclusion of a grazing period decreased the ratings of tenderness, flavour liking and overall liking, but age of the bulls at slaughter had no clear influence on sensory characteristics. PMID- 27692015 TI - Simple dietary criteria to improve serum n-3 fatty acid levels of mothers and their infants. AB - OBJECTIVE: Sufficient maternal dietary intake of n-3 fatty acids (FA) supports offspring development. We aimed to construct simple criteria for dietary counselling to improve intake of n-3 FA. DESIGN: Serum phospholipid FA from mothers and infants were analysed by GC one month after delivery. Dietary intake of foods during pregnancy and one month after delivery were recorded using 3 d food diaries and an index for healthy eating was calculated. Fish consumption was established by questionnaires. Dietary consumption of foods resulting in an increase in serum n-3 FA was defined. SETTING: A mother-child follow-up study in Southwest Finland. SUBJECTS: Mothers (n 90) and 1-month-old infants (n 63). RESULTS: After delivery, the mother's consumption of fish at least three times per week resulted in an increase in total serum n-3 FA (mean difference (95 % CI): 1.7 (0.7, 2.8) % of total FA, P<0.001) and DHA (1.1 (0.5, 1.8) % of total FA, P<0.001) compared with non-consumers. Persistent fish intake once weekly throughout pregnancy increased total serum n-3 FA (P=0.001) and DHA (P<0.001). Overall, a healthy diet (middle and highest tertiles of healthy eating index score v. the lowest tertile) resulted in higher total serum n-3 FA (P=0.004) and DHA (P=0.008). Mother's diet along with higher serum levels of n-3 FA were related to serum FA levels in 1-month-old infants. CONCLUSIONS: An overall healthy diet and persistent consumption of fish at least once weekly throughout pregnancy or more frequent fish intake three times per week increases n-3 FA in serum phospholipids of both mothers and their infants. PMID- 27692016 TI - Obesity services planning framework for interprofessional primary care organizations. AB - : Aim We report on a formative project to develop an organization-level planning framework for obesity prevention and management services. BACKGROUND: It is common when developing new services to first develop a logic model outlining expected outcomes and key processes. This can be onerous for single primary care organizations, especially for complex conditions like obesity. METHODS: The initial draft was developed by the research team, based on results from provider and patient focus groups in one large Family Health Team (FHT) in Ontario. This draft was reviewed and activities prioritized by 20 FHTs using a moderated electronic consensus process. A national panel then reviewed the draft. Findings Providers identified five main target groups: pregnancy to 2, 3-12, 13-18, 18+ years at health risk, and 18+ with complex care needs. Desired outcomes were identified and activities were prioritized under categories: raising awareness (eg, providing information and resources on weight-health), identification and initial management (eg, wellness care), follow-up management (eg, group programs), expanded services (eg, availability of team services), and practice initiatives (eg, interprofessional education). Overall, there was strong support for raising awareness by providing information on the weight-health connection and on community services. There was also strong support for growth assessment in pediatric care. In adults, there was strong support for wellness care/health check visits and episodic care to identify people for interventions, for group programs, and for additional provider education. CONCLUSIONS: Joint development by different teams proved useful for consensus on outcomes and for ensuring relevancy across practices. While priorities will vary depending on local context, the basic descriptions of care processes were endorsed by reviewers. Key next steps are to trial the use of the framework and for further implementation studies to find optimally effective approaches for obesity prevention and management across the lifespan. PMID- 27692017 TI - Internal Structure and Clinical Utility of the Anxiety Control Questionnaire Revised (ACQ-R) Spanish Version. AB - Perceived control has shown predictive value for anxiety severity symptoms as well as cognitive-behavior therapy outcomes. The most commonly used measure of perceived control is the Anxiety Control Questionnaire (ACQ), and more recently the ACQ Revised (ACQ-R). However, both questionnaires have shown structural inconsistencies among several studies. Also, although the ACQ and ACQ-R seem to be multidimensional instruments, a single total score have been commonly used. This study examined the internal structure of the ACQ-R Spanish version using exploratory factor and exploratory bi-factor analysis in a sample of 382 college students and 52 people diagnosed of panic disorder (with or without agoraphobia). Also, in this study we assessed the preliminary diagnostic value of the ACQ-R scores. The results indicated that the ACQ-R Spanish version structure consisted of two factors: one related with perceived control of internal emotional reactions (Emotion Control) and another related with perceived control of external events (Threat and Stress Control). Both specific factors can be adequately summarized by a general factor (General Anxiety Perception of Control; CFI = .973, TLI = .954, RMSEA = .039; p = .002), which accounted for 70% of the common explained variance. The correlations between the ACQ-R scores and with variables like anxiety (r = -.66) or anxiety sensitivity (r = -.50) presented the expected pattern of results. Either the two dimensions structure or the total score have proved to be a good tool to distinguish between participants with panic disorder and non-clinical samples (area under the curve = 0.79). PMID- 27692018 TI - The European School Fruit Scheme: impact on children's fruit and vegetable consumption in North Rhine-Westphalia, Germany. AB - OBJECTIVE: To assess the impact of the European School Fruit Scheme (SFS) in North Rhine-Westphalia, Germany, on children's fruit and vegetable (F&V) consumption, in particular frequency. DESIGN: The study consisted of a pre test/post-test design with an intervention (eight primary schools) and a control group (two primary schools). Children's F&V consumption frequency was measured prior to the introduction of the SFS in 2010 and after one year's delivery of F&V (2011). SETTING: Ten primary schools in North Rhine-Westphalia, Germany. SUBJECTS: In total, 499 primary-school children aged 6-11 years, 390 in the intervention and 109 in the control schools. RESULTS: Children highly appreciated the SFS. More than 90 % evaluated the programme positively. Children in the intervention group showed a significant increase in F&V intake frequency from baseline to follow-up, from on average 1.26 (sd 1.37) to 2.02 (sd 1.33) times/d (P=0.000). The intervention variable had a highly significant impact on children's F&V consumption frequency, even after controlling for gender, age and stay at school for lunch (beta=0.773; 95 % CI 0.59, 0.96). The SFS did not induce a reduction of F&V consumption at home. In the control group a non-significant decline in F&V consumption frequency from 1.31 (sd 1.26) to 1.18 (sd 1.34) times/d (P=0.325) was observed. CONCLUSION: One year after the programme's implementation, the SFS led to a significant short-term increase in children's F&V consumption. PMID- 27692019 TI - Practices, predictors and consequences of expressed breast-milk feeding in healthy full-term infants. AB - OBJECTIVE: To investigate the prevalence and predictors of expressed breast-milk feeding in healthy full-term infants and its association with total duration of breast-milk feeding. DESIGN: Prospective cohort study. SETTING: In-patient postnatal units of four public hospitals in Hong Kong. SUBJECTS: A total of 2450 mother-infant pairs were recruited in 2006-2007 and 2011-2012 and followed up prospectively for 12 months or until breast-milk feeding had stopped. RESULTS: Across the first 6 months postpartum, the rate of exclusive expressed breast-milk feeding ranged from 5.1 to 8.0 % in 2006-2007 and from 18.0 to 19.8 % in 2011 2012. Factors associated with higher rate of exclusive expressed breast-milk feeding included supplementation with infant formula, lack of previous breast milk feeding experience, having a planned caesarean section delivery and returning to work postpartum. Exclusive expressed breast-milk feeding was associated with an increased risk of early breast-milk feeding cessation when compared with direct feeding at the breast. The hazard ratio (95 % CI) ranged from 1.25 (1.04, 1.51) to 1.91 (1.34, 2.73) across the first 6 months. CONCLUSIONS: Mothers of healthy term infants should be encouraged and supported to feed directly at the breast. Exclusive expressed breast-milk feeding should be recommended only when medically necessary and not as a substitute for feeding directly at the breast. Further research is required to explore mothers' reasons for exclusive expressed breast-milk feeding and to identify the health outcomes associated with this practice. PMID- 27692020 TI - The Posttraumatic Growth Inventory: Factor Structure and Invariance in a Sample of Breast Cancer Patients and in a Non-Clinical Sample. AB - The Posttraumatic Growth Inventory (PTGI) is frequently used to assess positive changes following a traumatic event. The aim of the study is to examine the factor structure and the latent mean invariance of PTGI. A sample of 205 (M age = 54.3, SD = 10.1) women diagnosed with breast cancer and 456 (M age = 34.9, SD = 12.5) adults who had experienced a range of adverse life events were recruited to complete the PTGI and a socio-demographic questionnaire. We use Confirmatory Factor Analysis (CFA) to test the factor-structure and multi-sample CFA to examine the invariance of the PTGI between the two groups. The goodness of fit for the five-factor model is satisfactory for breast cancer sample (chi2(175) = 396.265; CFI = .884; NIF = .813; RMSEA [90% CI] = .079 [.068, .089]), and good for non-clinical sample (chi2(172) = 574.329; CFI = .931; NIF = .905; RMSEA [90% CI] = .072 [.065, .078]). The results of multi-sample CFA show that the model fit indices of the unconstrained model are equal but the model that uses constrained factor loadings is not invariant across groups. The findings provide support for the original five-factor structure and for the multidimensional nature of posttraumatic growth (PTG). Regarding invariance between both samples, the factor structure of PTGI and other parameters (i.e., factor loadings, variances, and co variances) are not invariant across the sample of breast cancer patients and the non-clinical sample. PMID- 27692021 TI - Effects of Brief Behavioural Activation on Approach and Avoidance Tendencies in Acute Depression: Preliminary Findings. AB - BACKGROUND: It has been suggested that the behavioural activation (BA) treatments for depression unfold their effects, at least partly, through changes in approach and avoidance tendencies. However, as yet, little research has examined the cognitive effects of these interventions. AIMS: This study investigated the impact of a single session of BA on depressive symptomatology, self-reported avoidance, and behavioural approach and avoidance tendencies. METHOD: Forty-six patients with a diagnosis of Major Depression were recruited from primary care psychological therapies services and block randomized to either a single session of behavioural activation (n = 22) or waiting list control (n = 24) delivered by an unblinded therapist. Self-reports of symptoms and cognitive factors were assessed before and after the one-week intervention phase. Approach and avoidance behavioural tendencies were assessed using the Approach-Avoidance Task (AAT). RESULTS: Data from 40 participants (n = 20 in each group) was available for analyses. Depressive symptoms significantly decreased, and activation significantly increased from before to after treatment in the treatment group, but not in the control group. Performance on the AAT showed a trend indicating increased approach to positive valence stimuli in the treatment group, but not in the control group. Mediational analyses indicated small indirect effects of self reported change in activation as mediators of the effect of condition on symptoms. CONCLUSIONS: The findings suggest that a single session of BA can have significant effects on symptoms in clinically depressed patients. Results hint at the possibility that increased behavioural approach might mediate the effect of BA. PMID- 27692022 TI - Addition of granulosa cell mass to the culture medium of oocytes derived from early antral follicles increases oocyte growth, ATP content, and acetylation of H4K12. AB - The main aim of the present study was to examine the hypothesis that an increase in the number of granulosa cells surrounding developing bovine oocytes results in both high ATP levels and an increase in the acetylation level of H4K12 in oocytes grown in vitro. Oocyte-granulosa cell complexes (OGCs) were collected from early antral follicles (EAFs, 0.4-0.7 mm in diameter), and individually cultured on 96 well plates with or without additional granulosa cell mass that had been prepared from other OGCs. After 16 days of culture, we examined: (i) the rate of antrum formation of the OGCs; (ii) the diameter, maturation, and fertilization rate of the oocytes; and (iii) the ATP content and acetylation level of H4K12 in the oocytes grown in vitro. Granulosa cell mass added to the culture medium contributed to the development of OGCs with a higher rate of antrum formation and oocyte growth. Furthermore, the addition of granulosa cells increased the ATP content and acetylation level of H4K12 in oocytes grown in vitro compared with those developed without addition of granulosa cells. In addition, there was a positive correlation between the ATP content in oocytes grown in vitro and the number of granulosa cells in the corresponding OGCs. The results suggest that granulosa cells play a role not only in the development of OGCs and the growth of oocytes, but also in the determination of ATP content and the acetylation of H4K12 in the oocytes developed in vitro. PMID- 27692024 TI - A home-based, carer-enhanced exercise program improves balance and falls efficacy in community-dwelling older people with dementia. AB - BACKGROUND: Older people with dementia are at increased risk of physical decline and falls. Balance and mood are significant predictors of falls in this population. The aim of this study was to determine the effect of a tailored home based exercise program in community-dwelling older people with dementia. METHODS: Forty-two participants with mild to moderate dementia were recruited from routine health services. All participants were offered a six-month home-based, carer enhanced, progressive, and individually tailored exercise program. Physical activity, quality of life, physical, and psychological assessments were administered at the beginning and end of the trial. RESULTS: Of 33 participants (78.6%) who completed the six-month reassessment ten (30%) reported falls and six (18%) multiple falls during the follow-up period. At reassessment, participants had better balance (sway on floor and foam), reduced concern about falls, increased planned physical activity, but worse knee extension strength and no change in depression scores. The average adherence to the prescribed exercise sessions was 45% and 22 participants (52%) were still exercising at trial completion. Those who adhered to >=70% of prescribed sessions had significantly better balance at reassessment compared with those who adhered to <70% of sessions. CONCLUSIONS: This trial of a tailored home-based exercise intervention presents preliminary evidence that this intervention can improve balance, concern about falls, and planned physical activity in community-dwelling older people with dementia. Future research should determine whether exercise interventions are effective in reducing falls and elucidate strategies for enhancing uptake and adherence in this population. PMID- 27692023 TI - Effects of initiating moderate wine intake on abdominal adipose tissue in adults with type 2 diabetes: a 2-year randomized controlled trial. AB - OBJECTIVE: To generate evidence-based conclusions about the effect of wine consumption on weight gain and abdominal fat accumulation and distribution in patients with type 2 diabetes. DESIGN: In the 2-year randomized controlled CASCADE (CArdiovaSCulAr Diabetes & Ethanol) trial, patients following a Mediterranean diet were randomly assigned to drink 150 ml of mineral water, white wine or red wine with dinner for 2 years. Visceral adiposity and abdominal fat distribution were measured in a subgroup of sixty-five participants, using abdominal MRI. SETTING: Ben-Gurion University of the Negev, Soroka-Medical Center and the Nuclear Research Center Negev, Israel. SUBJECTS: Alcohol-abstaining adults with well-controlled type 2 diabetes. RESULTS: Forty-eight participants (red wine, n 27; mineral water, n 21) who completed a second MRI measurement were included in the 2-year analysis. Similar weight losses (sd) were observed: red wine 1.3 (3.9) kg; water 1.0 (4.2) kg (P=0.8 between groups). Changes (95 % CI) in abdominal adipose-tissue distribution were similar: red wine, visceral adipose tissue (VAT) -3.0 (-8.0, 2.0) %, deep subcutaneous adipose tissue (DSAT) +5.2 ( 1.1, 11.6) %, superficial subcutaneous adipose tissue (SSAT) -1.9 (-5.0, 1.2) %; water, VAT -3.2 (-8.9, 2.5) %, DSAT +2.9 (-2.8, 8.6) %, SSAT -0.15 (-3.3, 2.9) %. No changes in antidiabetic medication and no substantial changes in energy intake (+126 (sd 2889) kJ/d (+30.2 (sd 690) kcal/d), P=0.8) were recorded. A 2-year decrease in glycated Hb (beta=0.28, P=0.05) was associated with a decrease in VAT. CONCLUSIONS: Moderate wine consumption, as part of a Mediterranean diet, in persons with controlled diabetes did not promote weight gain or abdominal adiposity. PMID- 27692025 TI - Development and validation of the patient evaluation scale (PES) for primary health care in Nigeria. AB - BACKGROUND: Questionnaires developed for patient evaluation of the quality of primary care are often focussed on primary care systems in developed countries. Aim To report the development and validation of the patient evaluation scale (PES) designed for use in the Nigerian primary health care context. METHODS: An iterative process was used to develop and validate the questionnaire using patients attending 28 primary health centres across eight states in Nigeria. The development involved literature review, patient interviews, expert reviews, cognitive testing with patients and waves of quantitative cross-sectional surveys. The questionnaire's content validity, internal structures, acceptability, reliability and construct validity are reported. Findings The full and shortened version of PES with 27 and 18 items, respectively, were developed through these process. The low item non-response from the serial cross-sectional surveys depicts questionnaire's acceptability among the local population. PES short form (SF) has Cronbach's alpha of 0.87 and three domains (codenamed 'facility', 'organisation' and 'health care') with Cronbach's alphas of 0.78, 0.79 and 0.81, respectively. Items in the multi-dimensional questionnaire demonstrated adequate convergent and discriminant properties. PES-SF scores show significant positive correlation with scores of the full PES and also discriminated population groups in support of a priori hypotheses. CONCLUSION: The PES and PES-SF contain items that are relevant to the needs of patients in Nigeria. The good measurement properties of the questionnaire demonstrates its potential usefulness for patient-focussed quality improvement activities in Nigeria. There is still need to translate these questionnaires into major languages in Nigeria and assess their validity against external quality criteria. PMID- 27692027 TI - Principal Component Analysis of Working Memory Variables during Child and Adolescent Development. AB - Correlation and Principal Component Analysis (PCA) of behavioral measures from two experimental tasks (Delayed Match-to-Sample and Oddball), and standard scores from a neuropsychological test battery (Working Memory Test Battery for Children) was performed on data from participants between 6-18 years old. The correlation analysis (p 1), the scores of the first extracted component were significantly correlated (p < .05) to most behavioral measures, suggesting some commonalities of the processes of age-related changes in the measured variables. The results suggest that this first component would be related to age but also to individual differences during the cognitive maturation process across childhood and adolescence stages. The fourth component would represent the speed-accuracy trade off phenomenon as it presents loading components with different signs for reaction times and errors. PMID- 27692026 TI - Providers' perceptions of barriers and facilitators to disclosure of alcohol use by women veterans. AB - : Aim To better understand barriers and facilitators that hinder or help women veterans discuss their alcohol use with providers in primary care in order to better identify problematic drinking and enhance provider-patient communication about harmful drinking. BACKGROUND: Women presenting to primary care may be less likely than men to disclose potentially harmful alcohol use. No studies have qualitatively examined the perspectives of primary care providers about factors that affect accurate disclosure of alcohol use by women veterans during routine clinic visits. METHODS: Providers (n=14) were recruited from primary care at two veterans Administration Women's Health Clinics in California, United States. An open-ended interview guide was developed from domains of the consolidated framework for implementation science. Interviews elicited primary care providers' perspectives on barriers and facilitators to women veterans' (who may or may not be using alcohol in harmful ways) disclosure of alcohol use during routine clinic visits. Interview data were analyzed deductively using a combination of template analysis and matrix analysis. Findings Participants reported six barriers and five facilitators that they perceived affect women veteran's decision to accurately disclose alcohol use during screenings and openness to discussing harmful drinking with a primary care provider. The most commonly described barriers to disclosure were stigma, shame, and discomfort, and co-occuring mental health concerns, while building strong therapeutic relationships and using probes to 'dig deeper' were most often described as facilitators. Findings from this study may enhance provider-patient discussions about alcohol use and help primary care providers to better identify problematic drinking among women veterans, ultimately improving patient outcomes. PMID- 27692028 TI - An evaluation of the CARES(r) Dementia Basics Program among caregivers. AB - BACKGROUND: In 2014, the state of Oregon established Oregon Care Partners to provide high quality, free training to all dementia caregivers. This study evaluated participants' changes in knowledge, sense of competency in dementia caregiving, and ability to identify person-centered caregiving techniques after completing CARES(r) Dementia Basics online program, one of the educational resources available through this initiative. METHODS: A convenience sample of informal and formal caregivers (N = 51) provided data at three points in time; pre-test, post-test, and a follow-up test after an additional 30-day period to determine sustained changes in knowledge, sense of competency, and person centered care. RESULTS: From pre-test to post-test, modest improvements were detected in sense of competence in performing dementia care (ps < 0.01) and dementia-based knowledge, F(2, 150) = 7.71, p < 0.001, a multivariate effect size of w 2 = 0.09. Even though improvements in sense of competency were not universal, three out of five individual items demonstrated positive growth from pre-test to post-test as well as four out of the five items from pre-test to follow-up test. Importantly, gains observed in dementia-based knowledge from pre test to post-test were largely maintained at the 30-day follow-up. No significant changes were found in the correct identification of person-centered techniques after the training F(5, 150) = 1.63, p = 0.19. CONCLUSIONS: Future research should investigate how best to maintain educational interventions within the caregiving environment and to assess subsequent skill change. PMID- 27692029 TI - Development of Ca2+-release mechanisms during oocyte maturation of the starfish Asterina pectinifera. AB - An important step for successful fertilization and further development is the increase in intracellular Ca2+ in the activated oocyte. It has been known that starfish oocytes become increasingly sensitive to inositol 1,4,5-trisphosphate (IP3) during meiotic maturation to exhibit highly efficient IP3-induced Ca2+ release (IICR) by the time of germinal vesicle breakdown (GVBD). However, we noted that the peak level of intracellular Ca2+ increase after insemination is already high in the maturing oocytes before GVBD. Using maturing oocytes before GVBD, we investigated Ca2+ release mechanisms other than IICR. We report here that Ca2+-release mechanisms dependent on nicotinic acid adenine dinucleotide phosphate (NAADP) and nicotinamide adenine dinucleotide (NADP), the precursor of NAADP, became functional prior to the development of IICR mechanisms. As with IP3, but unlike NAADP, the Ca2+ stores responsive to NADP are sensitized during the meiotic maturation induced by 1-methyladenine (1-MA). This suggests that the process may represent a physiological response to the maturation hormone. NADP dependent Ca2+ release in immature oocytes, however, did not induce oocyte maturation by itself, but was enhanced by the conditions mimicking the increases of intracellular Ca2+ and pH that take place in the maturing oocytes of starfish. PMID- 27692030 TI - Frailty and adverse outcomes: impact of multiple bed moves for older inpatients. AB - BACKGROUND: A consequence of pressure on hospitals to accommodate care needs of older patients is "boarding" or out-lying from their home ward. This may have greater adverse effects on older inpatients who are frail. METHODS: A retrospective matched cohort study was conducted in an outer metropolitan general hospital. Randomly selected patients hospitalized between July 2012 and June 2013 under the care of an Older Person Evaluation Review and Assessment (OPERA) team (n = 300) were age and sex matched with patients under the care of general physicians (n = 300). Frequency of boarding and number of bed moves were recorded for all patients. For patients who had three or more moves, adverse outcomes were compared between the two groups. RESULTS: A higher proportion of OPERA patients (n = 143; 47.7%) were out-lied from medical wards compared with 94 (31.3%) General Medicine patients (p < 0.001). Three or more bed moves were recorded for 67 (22.3%) OPERA and 24 (8%) General Medicine patients (p < 0.001). Of those with multiple moves, OPERA patients were more likely to have pre-morbid cognitive impairment (p = 0.005), to be moderately to severely frail (p = 0.016) and to suffer acute delirium and falls during admission (p = 0.03), compared with General Medicine patients. OPERA patients were also more at risk of adverse outcomes such as increased dependence, discharge to residential care or death (p = 0.023). CONCLUSION: Compared with age- and sex-matched General Medicine patients, OPERA patients were more likely to undergo multiple bed moves and out lying, which may have contributed to negative outcomes for these patients. PMID- 27692031 TI - Aggregation of cloned embryos in empty zona pellucida improves derivation efficiency of pig ES-like cells. AB - The development of embryonic stem cells (ESCs) from large animal species has become an important model for therapeutic cloning using ESCs derived by somatic cell nuclear transfer (SCNT). However, poor embryo quality and blastocyst formation have been major limitations for derivation of cloned ESCs (ntESCs). In this study, we have tried to overcome these problems by treating these cells with histone deacetylase inhibitors (HDACi) and aggregating porcine embryos. First, cloned embryos were treated with Scriptaid to confirm the effect of HDACi on cloned embryo quality. The Scriptaid-treated blastocysts showed significantly higher total cell numbers (29.50 +/- 2.10) than non-treated blastocysts (22.29 +/ 1.50, P < 0.05). Next, cloned embryo quality and blastocyst formation were analyzed in aggregates. Three zona-free, reconstructed, four-cell-stage SCNT embryos were injected into the empty zona of hatched parthenogenetic (PA) blastocysts. Blastocyst formation and total cell number of cloned blastocysts increased significantly for all aggregates (76.4% and 83.18 +/- 8.33) compared with non-aggregates (25.5% and 27.11 +/- 1.67, P < 0.05). Finally, aggregated blastocysts were cultured on a feeder layer to examine the efficiency of porcine ES-like cell derivation. Aggregated blastocysts showed a higher primary colony formation rate than non-aggregated cloned blastocysts (17.6 +/- 12.3% vs. 2.2 +/- 1.35%, respectively, P < 0.05). In addition, derived ES-like cells showed typical characters of ESCs. In conclusion, the aggregation of porcine SCNT embryos at the four-cell stage could be a useful technique for improving the development rate and quality of porcine-cloned blastocysts and the derivation efficiency of porcine ntESCs. PMID- 27692032 TI - Acinetobacter pakistanensis Abbas et al. 2014 is a later heterotypic synonym of Acinetobacter bohemicus Krizova et al. 2014. AB - Two novel species names, Acinetobacter bohemicus and Acinetobacter pakistanensis, appeared on validation list no. 161 (January 2015) under priority numbers 26 and 28, respectively. As the published data suggested a high similarity of the organisms associated with these names, we aimed to define their taxonomic relationship. The study set included all strains used in the original nomenclatural proposals, i.e. 25 strains of A. bohemicus and one strain of A. pakistanensis. The average nucleotide identity values (95.9 and 96.1 % based on blast and MUMmer, respectively) between the whole-genome sequences of A. bohemicus ANC 3994T and A. pakistanensis KCTC 42081T supported the identity of these type strains at the species level. Based on the genus-wide comparative analyses of the rpoB sequences and whole-cell fingerprints generated by matrix assisted laser desorption/ionization-time-of-flight MS, A. pakistanensis KCTC 42081T fell within the respective clusters formed by the 25 A. bohemicus strains. The same picture was obtained on the basis of comparative analysis of 16S rRNA gene sequences of KCTC 42081T and three A. bohemicus strains. Finally, the metabolic and physiological features of KCTC 42081T were found to be congruent with those of A. bohemicus. Based on these results, we conclude that Acinetobacter pakistanensis is a later heterotypic synonym of Acinetobacter bohemicus. PMID- 27692033 TI - Huakuichenia soli gen. nov., sp. nov., a new member of the family Microbacteriaceae, isolated from contaminated soil. AB - A novel Gram-stain-positive, non-motile, rod-shaped bacterial strain designated LIP-1T was isolated from the contaminated soil of a pesticide factory in Xinyi, China, was investigated for its taxonomic allocation by a polyphasic approach. Cell growth occurred at 16-37 degrees C (optimum, 30 degrees C), in the presence of 0-2.0 % (w/v) NaCl (optimum, 0 %) and at pH 6.0-9.0 (optimum, pH 7.0). The major fatty acids of strain LIP-1T were anteiso-C15 : 0 (50.8 %), iso C16 : 0 (17.6 %) and anteiso-C17 : 0 (17.4 %). The cell-wall peptidoglycan type was B2delta with 2,4-diaminobutyric acid as the diagnostic diamino acid. The major polar lipids were diphosphatidylglycerol and two unidentified glycolipids. The major menaquinones were MK-12 and MK-11. The genomic DNA G+C content was approximately 63.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain LIP-1T formed a distinct clade within the radiation of the family Microbacteriaceae and had the highest sequence similarity with Microbacterium ginsengisoli Gsoil 259T (96.01 %) followed by Cryobacterium arcticum SK1T (94.94 %). On the basis of the phylogenetic analyses and distinct phenotypic characteristics, a new genus, namely Huakuichenia gen. nov., is proposed, harbouring the novel species Huakuichenia soli gen. nov., sp. nov. with the type strain LIP-1T (=CCTCC AB 2015422T=KCTC 39698T). PMID- 27692034 TI - Carboxylicivirga flava sp. nov., isolated from marine surface sediment. AB - A novel bacterial strain, designated Q15T, was isolated from sediments obtained from the Bohai Sea in China and subjected to a polyphasic taxonomic study. Cells of strain Q15T were Gram-stain-negative, strictly aerobic rods that produced circular, flat, orange colonies. Phylogenetic analysis based on 16S rRNA gene sequences revealed that Q15T was affiliated with the genus Carboxylicivirga in the family Marinilabiliaceae of the phylum Bacteroidetes. Strain Q15T differed genotypically from the type strains of the three recognized species of this genus (Carboxylicivirga taeanensis MEBiC 08903T, Carboxylicivirga mesophila MEBiC 07026T and Carboxylicivirga linearis FB218T) and shared 94.0-95.2 % 16S rRNA gene sequence similarity with them. The DNA G+C content of strain Q15T was 44.7 mol%. The predominant cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso C17 : 0 3-OH, and menaquinone MK-7 was the main respiratory quinone. Polar lipids contained phosphatidylethanolamine, an unidentified aminolipid, an unidentified phospholipid and other unknown lipids. Based on the data from the current polyphasic analysis, a novel species, Carboxylicivirga flava sp. nov., is hereby proposed with Q15T (=CICC 23923T=KCTC 42707T) as the type strain. PMID- 27692035 TI - Acinetobactercelticus sp. nov., a psychrotolerant species widespread in natural soil and water ecosystems. AB - A novel, taxonomically unique group of six strains of the genus Acinetobacter was discovered during an exploratory study on strains culturable from soil and water natural ecosystems in the Bohemian part of the Czech Republic. Based on the comparative analyses of the 16S rRNA gene, gyrB and rpoB sequences, these strains formed strongly supported and internally coherent clusters (intracluster identities of >=99.9, >=96.1 and >=97.3 %, respectively), which were clearly separated from all known species of the genus Acinetobacter (<=98.7, <=83.2 and <=88.9 %, respectively). The distinctness of the group at the species level was evidenced also by the results of the genus-wide analyses of the whole-cell mass fingerprints of the six strains generated by matrix-assisted laser desorption/ionization-time-of-flight MS and the whole-genome sequence of a group member, ANC 4603T. Compared with the known species of the genus Acinetobacter, all six strains exhibited a unique phenotype, characterized by psychrotolerance (growth at 1 degrees C through 28 degrees C), the inability to grow at 32 degrees C and the ability to assimilate l-aspartate and malonate but not 2,3 butanediol or citrate. Based on these results, the name Acinetobacter celticus sp. nov. is proposed for the taxon represented by the six strains. The type strain is ANC 4603T (=CCM 8700T=CCUG 69239T=CNCTC 7549T). PMID- 27692036 TI - Idiomarina tyrosinivorans sp. nov., isolated from estuarine surface water. AB - A tyrosine-metabolizing, Gram-stain-negative, strictly aerobic, non-spore forming, curved-rod-shaped, motile (due to monopolar flagellum) marine bacterium, designated strain CC-PW-9T, was isolated from estuarine water off Pingtung, Taiwan. Strain CC-PW-9T not only shared highest 16S rRNA gene sequence similarities with Idiomarina representatives (96.4-93.4 %, n=26), but also formed a distinct phyletic lineage and coherent phylogenetic cluster associated with those species. Cells of strain CC-PW-9T grew with 6-12 % (w/v) NaCl, at 20-40 degrees C and at pH 6-9. It produced predominant amounts of phosphatidylethanolamine, plus diphosphatidylglycerol, phosphatidylglycerol, phosphatidylserine, two unidentified phospholipids, an unidentified phosphoglycolipid, two unidentified lipids and an unidentified aminolipid in moderate to trace amounts. Fatty acids such as iso-C15 : 0, iso-C17 : 0 and iso C17 : 1omega9c and/or C16 : 010-methyl (summed feature 9) were found in major amounts. The DNA G+C content was 51.1 mol%. Ubiquinone-8 (Q-8) was the sole respiratory quinone. Based on evidence from this polyphasic taxonomic study, strain CC-PW-9T is considered to represent a novel species of the genus Idiomarina, affiliated to the family Idiomarinaceae, for which the name Idiomarina tyrosinivorans sp. nov. is proposed. The type strain is CC-PW-9T (=JCM 19757T=BCRC 80745T). PMID- 27692037 TI - Gilvimarinus japonicus sp. nov., a cellulolytic and agarolytic marine bacterium isolated from coastal debris. AB - A cellulolytic and agarolytic bacterial strain, designated 12-2T, was isolated from a piece of cotton rope fragment washed ashore on a beach and was studied phenotypically, genotypically and phylogenetically. Analyses of 16S rRNA and gyrB gene sequences and DNA base composition suggested that the strain is a member of the genus Gilvimarinus. However, levels of 16S rRNA and gyrB gene sequence similarity between it and the type strains of Gilvimarinus species were no higher than 97.9 and 78.7 %, respectively, suggesting that the strain is distinct. Moreover, the results of DNA-DNA hybridization experiments and physiological characterization clearly differentiated the strain from its closest neighbours. The strain is therefore considered to represent a novel species of the genus Gilvimarinus, for which the name Gilvimarinus japonicus sp. nov. is proposed. The type strain is 12-2T (=NBRC 111987T=KCTC 52141T). PMID- 27692038 TI - Isolation and characterization of Acidobacterium ailaaui sp. nov., a novel member of Acidobacteria subdivision 1, from a geothermally heated Hawaiian microbial mat. AB - A novel member of Acidobacteria was isolated from a microbial mat growing on a geothermally heated dead tree trunk in Hawai'i Volcanoes National Park (HI, USA). The rod-shaped, Gram-negative capsulated cells of strain PMMR2T were non-motile and catalase and oxidase negative. Growth occurred aerobically from 15 to 55 degrees C (optimum, 40 degrees C) and at pH values from 4.5 to 7.0 (optimum, 6.5). A limited range of sugars and organic acids supported growth. However, results of a genomic analysis suggested that various polysaccharides might be hydrolysed as carbon sources, and evidence for pectin degradation was observed in liquid cultures. A genomic analysis also revealed genes for a Group 1f uptake hydrogenase; assays with liquid cultures confirmed hydrogen consumption, including uptake at sub-atmospheric concentrations. Nitrate was not dissimilated to nitrite. Major membrane fatty acids included iso-C15 : 0 and iso-C17 : 0. The G+C content was 57.2mol%. A comparative genome analysis revealed an average nucleotide identity of 72.2 % between PMMR2T and its nearest cultured phylogenetic neighbour, Acidobacterium capsulatum ATCC 51196T (=JCM 7670T); analysis of the 16S rRNA gene revealed a 96.8 % sequence identity with Acidobacterium capsulatum ATCC 51196T. These results and other phenotypic differences indicated that strain PMMR2T represents a novel species in the genus Acidobacterium, for which the name Acidobacterium ailaaui sp. nov. is proposed. The type strain, PMMR2T (=DSM 27394T=LMG 28340T), is the second formal addition to the genus Acidobacterium. PMID- 27692040 TI - Altererythrobacter sediminis sp. nov., isolated from lagoon sediments. AB - A Gram-stain-negative, non-motile, non-spore-forming, ovoid rod-shaped bacterium, designated strain CAU1172T, was isolated from lagoon sediments along the east coast of the Republic of Korea. Strain CAU1172T formed a yellow pigment on marine agar. Growth occurred at 20-37 degrees C (optimum, 30 degrees C), at pH 6.5-10 (optimum, 7.5) and in the presence of 0-4 % (w/v) NaCl (optimum, 1 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CAU1172T formed a separate lineage within the genus Altererythrobacter, and was most closely related to Altererythrobacter gangjinensis KJ7T (96.1 % similarity). Ubiquinone 10 (Q-10) was the predominant respiratory quinone. The dominant fatty acids were C18 : 1omega7c, C17 : 1omega6c and summed feature 3 (comprising C16 : 1omega7c and/or C16 : 1omega6c). The polar lipids were composed of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, sphingoglycolipid, phospatidylcholine and four unidentified lipids. The DNA G+C content of strain CAU1172T was 63.2 mol%. On the basis of phenotypic and chemotaxonomic data, strain CAU1172T represents a novel species of the genus Altererythrobacter, for which the name Altererythrobacter sediminis sp. nov. is proposed. The type strain is CAU1172T (=KCTC 42453T=NBRC 110917T). PMID- 27692039 TI - Proposed update to the taxonomy of the genera Hepacivirus and Pegivirus within the Flaviviridae family. AB - Proposals are described for the assignment of recently reported viruses, infecting rodents, bats and other mammalian species, to new species within the Hepacivirus and Pegivirus genera (family Flaviviridae). Assignments into 14 Hepacivirus species (Hepacivirus A-N) and 11 Pegivirus species (Pegivirus A-K) are based on phylogenetic relationships and sequence distances between conserved regions extracted from complete coding sequences for members of each proposed taxon. We propose that the species Hepatitis C virus is renamed Hepacivirus C in order to acknowledge its unique historical position and so as to minimize confusion. Despite the newly documented genetic diversity of hepaciviruses and pegiviruses, members of these genera remain phylogenetically distinct, and differ in hepatotropism and the possession of a basic core protein; pegiviruses in general lack these features. However, other characteristics that were originally used to support their division into separate genera are no longer definitive; there is overlap between the two genera in the type of internal ribosomal entry site and the presence of miR-122 sites in the 5' UTR, the predicted number of N linked glycosylation sites in the envelope E1 and E2 proteins, the presence of poly U tracts in the 3' UTR and the propensity of viruses to establish a persistent infection. While all classified hepaciviruses and pegiviruses have mammalian hosts, the recent description of a hepaci-/pegi-like virus from a shark and the likely existence of further homologues in other non-mammalian species indicate that further species or genera remain to be defined in the future. PMID- 27692041 TI - Functional analysis of a novel hydrogen peroxide resistance gene in Lactobacillus casei strain Shirota. AB - Lactic acid bacteria have a variety of mechanisms for tolerance to oxygen and reactive oxygen species, and these mechanisms differ among species. Lactobacillus casei strain Shirota grows well under aerobic conditions, indicating that the various systems involved in oxidative stress resistance function in this strain. To elucidate the mechanism of oxidative stress resistance in L. casei strain Shirota, we examined the transcriptome response to oxygen or hydrogen peroxide exposure. We then focused on an uncharacterized gene that was found to be up regulated by both oxygen and hydrogen peroxide stress; we named the gene hprA1 (hydrogen peroxide resistance gene). This gene is widely distributed among lactobacilli. We investigated the involvement of this gene in oxidative stress resistance, as well as the mechanism of tolerance to hydrogen peroxide. Growth of L. casei MS105, an hprA1-disrupted mutant, was not affected by oxygen stress, whereas the survival rate of MS105 after hydrogen peroxide treatment was markedly reduced compared to that of the wild-type. However, the activity of MS105 in eliminating hydrogen peroxide was similar to that of the wild-type. We cloned hprA1 from L. caseiShirota and purified recombinant HprA1 protein from Escherichia coli. We demonstrated that the recombinant HprA1 protein bound to iron and prevented the formation of a hydroxyl radical in vitro. Thus, HprA1 protein probably contributes to hydrogen peroxide tolerance in L. casei strain Shirota by binding to iron in the cells and preventing the formation of a hydroxyl radical. PMID- 27692042 TI - Characterization of germinants and their receptors for spores of non-food-borne Clostridium perfringens strain F4969. AB - Clostridium perfringens type A can cause both food poisoning (FP) and non-food borne (NFB) gastrointestinal diseases. Our previous study reported that a mixture of l-asparagine and KCl (AK)-germinated spores of FP and NFB isolates well, but KCl and, to a lesser extent, l-asparagine induced spore germination only in FP isolates. We now report that the germination response of FP and NFB spores differsignificantly in several defined germinants and rich media. Spores of NFB strain F4969 gerAA, gerKA-KC or gerKC mutants lacking specific germinant receptor proteins germinated more slowly than wild-type spores with rich media, did not germinate with AK and germinated poorly compared to wild-type spores with l cysteine. The germination defects in the gerKA-KC spores were largely due to loss of GerKC as (i) gerKA spores germinated significantly with all tested germinants, while gerKC spores exhibited poor or no germination; and (ii) germination defects in gerKC spores were largely restored by expressing the wild-type gerKA-KC operon in trans. We also found that gerKA-KC, gerAA and gerKC spores, but not gerKA spores, released dipicolinic acid at a slower rate than wild-type spores with AK. The colony-forming efficiency of F4969 gerKC spores was also ~35-fold lower than that of wild-type spores, while gerAA and wild-type spores had similar viability. Collectively, these results suggest that the GerAA and GerKC proteins play roles in normal germination of C. perfringens NFB isolates and that GerKC, but not GerAA, is important in these spores' apparent viability. PMID- 27692043 TI - Wolbachia restricts insect-specific flavivirus infection in Aedes aegypti cells. AB - Mosquito-borne viruses are known to cause disease in humans and livestock and are often difficult to control due to the lack of specific antivirals and vaccines. The Wolbachia endosymbiont has been widely studied for its ability to restrict positive-strand RNA virus infection in mosquitoes, although little is known about the precise antiviral mechanism. In recent years, a variety of insect-specific viruses have been discovered in mosquitoes and an interaction with mosquito-borne viruses has been reported for some of them; however, nothing is known about the effect of Wolbachia on insect-specific virus infection in mosquitoes. Here, we show that transinfection of the Drosophila-derived wMelPop Wolbachia strain into Aedes aegypti-derived cells resulted in inhibition and even clearance of the persistent cell-fusing agent flavivirus infection in these cells. This broadens the antiviral activity of Wolbachia from acute infections to persistent infections and from arboviruses to mosquito-specific viruses. In contrast, no effect on the Phasi Charoen-like bunyavirus persistent infection in these cells was observed, suggesting a difference in Wolbachia inhibition between positive- and negative-strand RNA viruses. PMID- 27692044 TI - Molecular epidemiology and the evolution of human coxsackievirus A6. AB - Coxsackievirus A6 (CV-A6) is a major aetiologic agent for hand, foot and mouth disease (HFMD) in recent years. HFMD outbreaks associated with CV-A6 resulted from the evolutionary dynamics of CV-A6 and the appearance of novel recombinant forms (RFs). To examine this, 151 variants collected in 2013 and 2014 from Germany, Spain, Sweden, Denmark and Thailand were genotyped for the VP1 capsid and 3Dpol genes. Analysis of the VP1 gene showed an increasing correspondence between CV-A6 genome recombination and sequence divergence (estimated substitution rate of 8.1*10-3 substitutions site-1 year-1 and RF half-life of 3.1 years). Bayesian phylogenetic analysis showed that recent recombination groups (RF-E, -F, -H, -J and -K) shared a common ancestor (RF-A). Thirty-nine full length genomes of different RFs revealed recombination breakpoints between the 2A 2C and the 5' UTRs. The emergence of new CV-A6 recombination groups has become widespread in Europe and Asia within the last 8 years. PMID- 27692045 TI - Herpes simplex virus particles interact with chemokines and enhance cell migration. AB - Herpes simplex virus type 1 and type 2 (HSV-1 and HSV-2, respectively) are among the most prevalent human pathogens, causing a variety of diseases. HSV modulation of the chemokine network remains poorly understood. We have previously identified secreted glycoprotein G (SgG) as the first viral chemokine-binding protein that enhances chemokine function as a novel viral immunomodulatory mechanism. However, gG is also present at the viral envelope and its role in the virus particle remains unknown. Here we have addressed the chemokine-binding capacity of HSV particles and the functionality of such interaction in vitro. We adapted surface plasmon resonance assays and demonstrated the ability of HSV particles to bind a specific set of human chemokines with high affinity. Moreover, we identified gG as the envelope glycoprotein mediating such interaction, as shown by the lack of binding to a HSV-1 gG mutant. In contrast to HSV-1, HSV-2 gG is cleaved and the chemokine-binding domain is secreted (SgG2). However, we found that HSV-2 particles retain the ability to bind chemokines, potentially through SgG2 associated to the viral envelope or non-processed precursor protein. Moreover, we found that HSV particles increase cell migration independently of chemokine binding to envelope gG. This work provides insights into HSV manipulation of the host immune system. PMID- 27692046 TI - Transfer of the potato plant isolates of Pectobacterium wasabiae to Pectobacterium parmentieri sp. nov. AB - Pectobacterium wasabiae was originally isolated from Japanese horseradish (Eutrema wasabi), but recently some Pectobacterium isolates collected from potato plants and tubers displaying blackleg and soft rot symptoms were also assigned to P. wasabiae. Here, combining genomic and phenotypical data, we re-evaluated their taxonomic position. PacBio and Illumina technologies were used to complete the genome sequences of P. wasabiae CFBP 3304T and RNS 08-42-1A. Multi-locus sequence analysis showed that the P. wasabiae strains RNS 08-42-1A, SCC3193, CFIA1002 and WPP163, which were collected from potato plant environment, constituted a separate clade from the original Japanese horseradish P. wasabiae. The taxonomic position of these strains was also supported by calculation of the in-silico DNA DNA hybridization, genome average nucleotide indentity, alignment fraction and average nucleotide indentity values. In addition, they were phenotypically distinguished from P. wasabiae strains by producing acids from (+)-raffinose, alpha-d(+)-alpha-lactose, d(+)-galactose and (+)-melibiose but not from methyl alpha-d-glycopyranoside, (+)-maltose or malonic acid. The name Pectobacterium parmentieri sp. nov. is proposed for this taxon; the type strain is RNS 08-42-1AT (=CFBP 8475T=LMG 29774T). PMID- 27692047 TI - Discovery of a polyomavirus in European badgers (Meles meles) and the evolution of host range in the family Polyomaviridae. AB - Polyomaviruses infect a diverse range of mammalian and avian hosts, and are associated with a variety of symptoms. However, it is unknown whether the viruses are found in all mammalian families and the evolutionary history of the polyomaviruses is still unclear. Here, we report the discovery of a novel polyomavirus in the European badger (Meles meles), which to our knowledge represents the first polyomavirus to be characterized in the family Mustelidae, and within a European carnivoran. Although the virus was discovered serendipitously in the supernatant of a cell culture inoculated with badger material, we subsequently confirmed its presence in wild badgers. The European badger polyomavirus was tentatively named Meles meles polyomavirus 1 (MmelPyV1). The genome is 5187 bp long and encodes proteins typical of polyomaviruses. Phylogenetic analyses including all known polyomavirus genomes consistently group MmelPyV1 with California sea lion polyomavirus 1 across all regions of the genome. Further evolutionary analyses revealed phylogenetic discordance amongst polyomavirus genome regions, possibly arising from evolutionary rate heterogeneity, and a complex association between polyomavirus phylogeny and host taxonomic groups. PMID- 27692048 TI - Infectivity of wild bird-origin avian paramyxovirus serotype 1 and vaccine effectiveness in chickens. AB - Newcastle disease virus, a prototype avian paramyxovirus serotype 1 (APMV-1), causes economically devastating disease in avian species around the world. Newcastle disease is enzootic in Pakistan and recurrent outbreaks are frequent in multiple avian species even after continuous and extensive use of vaccines. A number of APMV-1 and pigeon paramyxovirus serotype 1 (PPMV-1) strains have been isolated and genetically characterized in recent years. However, the impact of recently characterized wild bird-origin APMVs in domestic poultry, and the potency of routinely used vaccines against these novel and genetically diverse viruses remain unknown. Here, we applied next-generation sequencing for unbiased complete genome characterization of APMV-1 and PPMV-1 strains isolated from clinically diseased peacocks (Pavocristatus) and pigeons (Columbalivia), respectively. Global phylodynamics and evolutionary analysis demonstrates Pigeon/MZS-UVAS-Pak/2014 is clustered into lineage 4 (or genotype VI) and Peacock/MZS-UVAS-Pak/2014 into lineage 5 (or genotype VII). The genomes of both isolates encoded for polybasic residues (112RRQKR?F117) at the fusion protein cleavage motif along with a number of important substitutions in the surface glycoproteins compared with the vaccine strains. Clinicopathological and immunological investigations in domesticated chickens indicate that these isolates can potentially transmit between tested avian species, can cause systemic infections, and can induce antibodies that are unable to prevent virus shedding. Collectively, the data from these genomic and biological assessments highlight the potential of wild birds in transmitting APMVs to domesticated chickens. The study also demonstrates that the current vaccine regimens are incapable of providing complete protection against wild bird-origin APMVs and PPMVs. PMID- 27692061 TI - Effects of freezing and activation on membrane quality and DNA damage in Xenopus tropicalis and Xenopus laevis spermatozoa. AB - There is growing concern over the effect of sperm cryopreservation on DNA integrity and the subsequent development of offspring generated from this cryopreserved material. In the present study, membrane integrity and DNA stability of Xenopus laevis and Xenopus tropicalis spermatozoa were evaluated in response to cryopreservation with or without activation, a process that happens upon exposure to water to spermatozoa of some aquatic species. A dye exclusion assay revealed that sperm plasma membrane integrity in both species decreased after freezing, more so for X. laevis than X. tropicalis spermatozoa. The sperm chromatin dispersion (SCD) test showed that for both X. tropicalis and X. laevis, activated frozen spermatozoa produced the highest levels of DNA fragmentation compared with all fresh samples and frozen non-activated samples (P<0.05). Understanding the nature of DNA and membrane damage that occurs in cryopreserved spermatozoa from Xenopus species represents the first step in exploiting these powerful model organisms to understand the developmental consequences of fertilising with cryopreservation-damaged spermatozoa. PMID- 27692062 TI - Assessing change in perceived community leadership readiness in the Obesity Prevention and Lifestyle program. AB - Issue addressed The context of community-based childhood obesity prevention programs can influence the effects of these intervention programs. Leadership readiness for community mobilisation for childhood obesity prevention is one such contextual factor. This study assessed perceived community leadership readiness (PCLR) at two time points in a state-wide, multisite community-based childhood obesity prevention program. Methods PCLR was assessed across 168 suburbs of 20 intervention communities participating in South Australia's Obesity Prevention and Lifestyle (OPAL) program. Using a validated online PCLR tool, four key respondents from each community rated each suburb within their respective community on a nine-point scale for baseline and 2015. Average PCLR and change scores were calculated using the general linear model with suburbs nested in communities. Relationships between demographic variables and change in PCLR were evaluated using multiple regression. Ease of survey use was also assessed. Results Average PCLR increased between baseline (3.51, s.d.=0.82) and 2015 (5.23, s.d.=0.89). PCLR rose in 18 of 20 intervention communities. PCLR was inversely associated with suburb population size (r2=0.03, P=0.03, beta=-0.25) and positively associated with intervention duration (r2 change=0.08, P=0.00, beta=0.29). Only 8% of survey respondents considered the online assessment tool difficult to use. Conclusions PCLR increased over the course of the OPAL intervention. PCLR varied between and within communities. Online assessment of PCLR has utility for multisite program evaluations. So what? Use of a novel, resource-efficient online tool to measure the key contextual factors of PCLR has enabled a better understanding of the success and generalisability of the OPAL program. PMID- 27692064 TI - Phenotypic plasticity as an adaptation to a functional trade-off. AB - We report the evolution of a phenotypically plastic behavior that circumvents the hardwired trade-off that exists when resources are partitioned between growth and motility in Escherichia coli. We propagated cultures in a cyclical environment, alternating between growth up to carrying capacity and selection for chemotaxis. Initial adaptations boosted overall swimming speed at the expense of growth. The effect of the trade-off was subsequently eased through a change in behavior; while individual cells reduced motility during exponential growth, the faction of the population that was motile increased as the carrying capacity was approached. This plastic behavior was produced by a single amino acid replacement in FliA, a regulatory protein central to the chemotaxis network. Our results illustrate how phenotypic plasticity potentiates evolvability by opening up new regions of the adaptive landscape. PMID- 27692065 TI - Sparse activity of identified dentate granule cells during spatial exploration. AB - In the dentate gyrus - a key component of spatial memory circuits - granule cells (GCs) are known to be morphologically diverse and to display heterogeneous activity profiles during behavior. To resolve structure-function relationships, we juxtacellularly recorded and labeled single GCs in freely moving rats. We found that the vast majority of neurons were silent during exploration. Most active GCs displayed a characteristic spike waveform, fired at low rates and showed spatial activity. Primary dendritic parameters were sufficient for classifying neurons as active or silent with high accuracy. Our data thus support a sparse coding scheme in the dentate gyrus and provide a possible link between structural and functional heterogeneity among the GC population. PMID- 27692063 TI - ATPase activity of the DEAD-box protein Dhh1 controls processing body formation. AB - Translational repression and mRNA degradation are critical mechanisms of posttranscriptional gene regulation that help cells respond to internal and external cues. In response to certain stress conditions, many mRNA decay factors are enriched in processing bodies (PBs), cellular structures involved in degradation and/or storage of mRNAs. Yet, how cells regulate assembly and disassembly of PBs remains poorly understood. Here, we show that in budding yeast, mutations in the DEAD-box ATPase Dhh1 that prevent ATP hydrolysis, or that affect the interaction between Dhh1 and Not1, the central scaffold of the CCR4 NOT complex and an activator of the Dhh1 ATPase, prevent PB disassembly in vivo. Intriguingly, this process can be recapitulated in vitro, since recombinant Dhh1 and RNA, in the presence of ATP, phase-separate into liquid droplets that rapidly dissolve upon addition of Not1. Our results identify the ATPase activity of Dhh1 as a critical regulator of PB formation. PMID- 27692067 TI - Social observation enhances cross-environment activation of hippocampal place cell patterns. AB - Humans and animals frequently learn through observing or interacting with others. The local enhancement theory proposes that presence of social subjects in an environment facilitates other subjects' understanding of the environment. To explore the neural basis of this theory, we examined hippocampal place cells, which represent spatial information, in rats as they stayed in a small box while a demonstrator rat running on a separate, nearby linear track, and as they ran on the same track themselves. We found that place cell firing sequences during self running on the track also appeared in the box. This cross-environment activation occurred even prior to any self-running experience on the track and was absent without a demonstrator. Our data thus suggest that social observation can facilitate the observer's spatial representation of an environment without actual self-exploration. This finding may contribute to neural mechanisms of local enhancement. PMID- 27692066 TI - Macrophage PPARgamma inhibits Gpr132 to mediate the anti-tumor effects of rosiglitazone. AB - Tumor-associated macrophage (TAM) significantly contributes to cancer progression. Human cancer is enhanced by PPARgamma loss-of-function mutations, but inhibited by PPARgamma agonists such as TZD diabetes drugs including rosiglitazone. However, it remains enigmatic whether and how macrophage contributes to PPARgamma tumor-suppressive functions. Here we report that macrophage PPARgamma deletion in mice not only exacerbates mammary tumor development but also impairs the anti-tumor effects of rosiglitazone. Mechanistically, we identify Gpr132 as a novel direct PPARgamma target in macrophage whose expression is enhanced by PPARgamma loss but repressed by PPARgamma activation. Functionally, macrophage Gpr132 is pro-inflammatory and pro tumor. Genetic Gpr132 deletion not only retards inflammation and cancer growth but also abrogates the anti-tumor effects of PPARgamma and rosiglitazone. Pharmacological Gpr132 inhibition significantly impedes mammary tumor malignancy. These findings uncover macrophage PPARgamma and Gpr132 as critical TAM modulators, new cancer therapeutic targets, and essential mediators of TZD anti cancer effects. PMID- 27692068 TI - The novel SH3 domain protein Dlish/CG10933 mediates fat signaling in Drosophila by binding and regulating Dachs. AB - Much of the Hippo and planar cell polarity (PCP) signaling mediated by the Drosophila protocadherin Fat depends on its ability to change the subcellular localization, levels and activity of the unconventional myosin Dachs. To better understand this process, we have performed a structure-function analysis of Dachs, and used this to identify a novel and important mediator of Fat and Dachs activities, a Dachs-binding SH3 protein we have named Dlish. We found that Dlish is regulated by Fat and Dachs, that Dlish also binds Fat and the Dachs regulator Approximated, and that Dlish is required for Dachs localization, levels and activity in both wild type and fat mutant tissue. Our evidence supports dual roles for Dlish. Dlish tethers Dachs to the subapical cell cortex, an effect partly mediated by the palmitoyltransferase Approximated under the control of Fat. Conversely, Dlish promotes the Fat-mediated degradation of Dachs. PMID- 27692069 TI - The fail-safe mechanism of post-transcriptional silencing of unspliced HAC1 mRNA. AB - HAC1 encodes a transcription factor that is the central effector of the unfolded protein response (UPR) in budding yeast. When the UPR is inactive, HAC1 mRNA is stored as an unspliced isoform in the cytoplasm and no Hac1 protein is detectable. Intron removal is both necessary and sufficient to relieve the post transcriptional silencing of HAC1 mRNA, yet the precise mechanism by which the intron prevents Hac1 protein accumulation has remained elusive. Here, we show that a combination of inhibited translation initiation and accelerated protein degradation-both dependent on the intron-prevents the accumulation of Hac1 protein when the UPR is inactive. Functionally, both components of this fail-safe silencing mechanism are required to prevent ectopic production of Hac1 protein and concomitant activation of the UPR. Our results provide a mechanistic understanding of HAC1 regulation and reveal a novel strategy for complete post transcriptional silencing of a cytoplasmic mRNA.

PMID- 27692070 TI - Viral RNA switch mediates the dynamic control of flavivirus replicase recruitment by genome cyclization. AB - Viral replicase recruitment and long-range RNA interactions are essential for RNA virus replication, yet the mechanism of their interplay remains elusive. Flaviviruses include numerous important human pathogens, e.g., dengue virus (DENV) and Zika virus (ZIKV). Here, we revealed a highly conserved, conformation tunable cis-acting element named 5'-UAR-flanking stem (UFS) in the flavivirus genomic 5' terminus. We demonstrated that the UFS was critical for efficient NS5 recruitment and viral RNA synthesis in different flaviviruses. Interestingly, stabilization of the DENV UFS impaired both genome cyclization and vRNA replication. Moreover, the UFS unwound in response to genome cyclization, leading to the decreased affinity of NS5 for the viral 5' end. Thus, we propose that the UFS is switched by genome cyclization to regulate dynamic RdRp binding for vRNA replication. This study demonstrates that the UFS enables communication between flavivirus genome cyclization and RdRp recruitment, highlighting the presence of switch-like mechanisms among RNA viruses.

AB - Big data are large volumes of digital data that can be collected from disparate sources and are challenging to analyze. These data are often described with the five "Vs": volume, velocity, variety, veracity, and value. Perioperative nurses contribute to big data through documentation in the electronic health record during routine surgical care, and these data have implications for clinical decision making, administrative decisions, quality improvement, and big data science. This article explores methods to improve the quality of perioperative nursing data and provides examples of how these data can be combined with broader nursing data for quality improvement. We also discuss a national action plan for nursing knowledge and big data science and how perioperative nurses can engage in collaborative actions to transform health care. Standardized perioperative nursing data has the potential to affect care far beyond the original patient. PMID- 27692076 TI - Totally Endoscopic Robotic Mitral Valve Surgery. AB - Mitral valve dysfunction can seriously impair patients' lives and may require valve repair or replacement. Surgery can be performed using techniques including sternotomy; right thoracotomy with or without robot assistance; and the totally endoscopic robotic technique, which requires percutaneous techniques, femoral cannulation, and endovascular aortic cross-clamping. The totally endoscopic robotic technique has been facilitated by minimally invasive surgical techniques, the evolution of endoscopic techniques, and the development of surgical robots. These advances have enhanced the view of the surgical field and provide better exposure for the repair or replacement of the mitral valve and subvalvular apparatus. This article describes the totally endoscopic robotic approach to mitral valve surgery as performed at Temple University Hospital, Philadelphia, Pennsylvania. PMID- 27692071 TI - Evidence for evolutionary divergence of activity-dependent gene expression in developing neurons. AB - Evolutionary differences in gene regulation between humans and lower mammalian experimental systems are incompletely understood, a potential translational obstacle that is challenging to surmount in neurons, where primary tissue availability is poor. Rodent-based studies show that activity-dependent transcriptional programs mediate myriad functions in neuronal development, but the extent of their conservation in human neurons is unknown. We compared activity-dependent transcriptional responses in developing human stem cell derived cortical neurons with those induced in developing primary- or stem cell derived mouse cortical neurons. While activity-dependent gene-responsiveness showed little dependence on developmental stage or origin (primary tissue vs. stem cell), notable species-dependent differences were observed. Moreover, differential species-specific gene ortholog regulation was recapitulated in aneuploid mouse neurons carrying human chromosome-21, implicating promoter/enhancer sequence divergence as a factor, including human-specific activity-responsive AP-1 sites. These findings support the use of human neuronal systems for probing transcriptional responses to physiological stimuli or indeed pharmaceutical agents. PMID- 27692077 TI - Perioperative Heat Loss Prevention-A Feasibility Trial. AB - Preventing unplanned perioperative hypothermia is crucial. Thermal reflective blankets may reduce heat loss, promote normothermia, increase patient comfort, and decrease cotton blanket expenses. Our purpose was to determine whether a thermal reflective blanket plus one warmed cotton blanket provides better temperature control and thermal comfort than warmed cotton blankets only. We compared two groups of perioperative patients who received a thermal reflective blanket plus one warmed cotton blanket (n = 110) or warmed cotton blankets only (n = 114) for temperature control and comfort, and we evaluated outcomes in the preoperative holding area, the OR, and the postanesthesia care unit. There were no significant differences in patient temperature or comfort between groups. Use of thermal reflective blankets led to significantly reduced use of warmed cotton blankets (t209 = -10.51, P < .001), and a cost threshold for clinical adoption was identified. The hospital opted not to purchase thermal reflective blankets because of equivalent performance and minimal cost savings. PMID- 27692078 TI - Achieving Cost Reduction Through Data Analytics. AB - The reimbursement structure of the US health care system is shifting from a volume-based system to a value-based system. Adopting a comprehensive data analytics platform has become important to health care facilities, in part to navigate this shift. Hospitals generate plenty of data, but actionable analytics are necessary to help personnel interpret and apply data to improve practice. Perioperative services is an important revenue-generating department for hospitals, and each perioperative service line requires a tailored approach to be successful in managing outcomes and controlling costs. Perioperative leaders need to prepare to use data analytics to reduce variation in supplies, labor, and overhead. Mercy, based in Chesterfield, Missouri, adopted a perioperative dashboard that helped perioperative leaders collaborate with surgeons and perioperative staff members to organize and analyze health care data, which ultimately resulted in significant cost savings. PMID- 27692079 TI - Body Art and the Perioperative Process. AB - Body modification, also known as body art, has been a common cultural practice for thousands of years and includes body piercings, transdermal and subdermal implants, tattoos, scarification, body stretching and sculpting, dental grills, and nail art. Perioperative nurses must learn more about body art to provide nonjudgmental, nonprejudicial care and to ensure patient safety when they prepare patients for surgery. A welcoming environment engages patients and fosters communication so that patients are more likely to share hidden body art. It is also necessary for the preoperative nurse to communicate with the perioperative team about patients' body art to avoid airway complications, tissue trauma, pressure ulcers, burns, postoperative surgical site infections, or distorted fluoroscopy or magnetic resonance images. Identifying patients' body art in advance allows the perioperative team to be better prepared to deliver safe care. PMID- 27692080 TI - Crisis Management of Hypoxia in the OR.

METHODS: Most (131/140) patients from a pediatric practice who were tested for influenza in the 2012-2013 season were enrolled. Medical records plus questionnaires determined vaccine and past disease histories and influenza vaccine attitudes. Influenza-negative tested cases (n = 65) and negative controls (n = 110) closely age-matched to 55 test positive cases were compared with influenza-positive cases (n = 66) regarding prior influenza, vaccine efficacy, and limited vaccine season conflicting with birth dates and preventative visit timing to determine possible validity of reasons given for underutilization. RESULTS: The most common parental reason for not vaccinating was lack of perceived need. History of previous influenza was significantly (P < .0001) associated with disease. Live attenuated vaccine rates were greater in controls than in influenza patients for ages 2-18 years (P < .005) and for ages 6-18 years (P < .0001), whereas injectable vaccine rates were not (P = .30 and P = .60, respectively). Most positive cases (59%) and controls (89%) had no prior influenza. CONCLUSIONS: Prior influenza disease may be a risk factor for infection that could influence vaccination benefit. Live attenuated influenza vaccine outperformed trivalent inactivated influenza vaccine. Limited disease experience in individuals with low influenza vaccination rates, along with vaccine efficacy limitations, lends validity to some underutilization. PMID- 27692088 TI - Introducing In Vivo. PMID- 27692089 TI - Immunoproteomic characterization of a Dermatophagoides farinae extract used in the treatment of canine atopic dermatitis. AB - BACKGROUND: Canine atopic dermatitis is a pruritic allergic skin disease. House dust mites have been identified as the main non-seasonal responsible agent. Unlike in human allergic patients, groups 1 and 2 antigens have been described as minor allergens in dogs, while groups 15 and 18 are considered the major allergens. Despite these differences, allergic dogs have traditionally been treated using extracts intended for human immunotherapy. OBJECTIVES: To investigate the immunological characteristics and the allergen reactivity of dogs with atopic dermatitis using a Dermatophagoides farinae commercial extract. METHODS: Eighteen dogs diagnosed with atopic dermatitis and 3 healthy control dogs from the Iberian Peninsula were included in the study. All the animals were older than 12 months, from both sexes and different breeds and showed positive specific IgE against D. farinae (>2500 ELISA Absorbance Units). The D. farinae allergenic extract used in this study was manufactured and characterized. The allergenic profile of the dogs was investigated by immunoblot and specific IgE, IgG, IgG1 and IgG2 measured by direct ELISA. Allergen identity was confirmed by immunoblot inhibition and mass spectrometry analyses. RESULTS: The results confirmed the relevance of groups 15 and 18 antigens, but also groups 1, 2 and other medium molecular weight allergens in the sensitization of dogs with atopic dermatitis. Immunoblot inhibition and mass spectrometry assays confirmed these results. Relevant allergens were quantified by scanning densitometry (Der f 1: 17MUg/mg, Der f 2: 20.3MUg/mg, Der f 15: 18.1MUg/mg and Der f 18: 9.4MUg/mg). Concerning immunoglobulins profile, differences in IgE and IgG1 levels were observed between non-atopic and atopic dogs. CONCLUSIONS: The commercial D. farinae extract characterized in this study contains the major allergens involved in the sensitization of dogs with atopic dermatitis, representing a suitable candidate for its use in the diagnosis and immunotherapy of mite allergic dogs. PMID- 27692090 TI - Comparison of cytokine responses between dogs with sepsis and dogs with immune mediated hemolytic anemia. AB - Cytokine abnormalities have been described previously in dogs with varied immune mediated and inflammatory conditions such as IMHA and sepsis. The purpose of this study was to establish references ranges for cytokine levels in dogs and to compare cytokine levels in normal dogs and dogs with two common inflammatory diseases (sepsis and IMHA). We hypothesized that cytokine response profiles in dogs with sepsis would be significantly different from those in dogs with IMHA due to the very different etiologies of the two diseases. Concentrations of 14 different cytokines in serum were measured and values grouped according to cytokine function. Serum from clinically normal dogs was used to establish cytokine concentration reference ranges. Rank values for each of the 4 cytokine groups were then compared statistically between healthy control, septic and IMHA dogs. This analysis revealed differences in cytokine groups between dogs with sepsis and IMHA when compared to healthy control dogs but no difference between dogs with either of these conditions. In conclustion, dogs in the early stage of sepsis and IMHA have similar circulating cytokines despite different etiologies suggesting activation of common immunologic pathways. This may have implications for immunotherapy of immune mediated diseases in dogs of varying etiology. PMID- 27692091 TI - Marek's disease virus immunosuppression alters host cellular responses and immune gene expression in the skin of infected chickens. AB - Marek's disease virus (MDV), a highly cell-associated lymphotropic alpha herpesvirus, is the causative agent of Marek's disease (MD) in domestic chickens. MDV replicates in chicken lymphocytes and establishes a latent infection within CD4+ T cells. The latently infected CD4+ T cells carry the virus to visceral organs, peripheral nerves, and feather follicle epithelium (FFE). FFE is the only anatomical site where infectious enveloped cell-free virus particles are produced and disseminated into the environment. This study investigated the immunological responses and mechanism of viral-induced immunosuppression and immune evasion in the FFE. Strong viral replication and lack of a significant number of cytotoxic T lymphocytes (CTL) in the infected tissues was prominent. Although the overall gene expression pattern was suggestive of a Th1 type immune response, the expression levels of several key immune genes were down regulated in the infected tissues. The mechanism of MDV-induced immunosuppression appears to be through inhibition of CTL function due to down regulation of CD8 glycoprotein and/or blocking of CTL migration due to decrease expression of cell adhesion molecules. PMID- 27692092 TI - Demonstration of the ability of a canine Lyme vaccine to reduce the incidence of histological synovial lesions following experimentally-induced canine Lyme borreliosis. AB - Lyme disease in dogs can be effectively prevented by vaccination against antigens expressed by the spirochete Borrelia burgdorferi during transmission by the tick vector Ixodes sp. Lyme vaccine efficacy has traditionally been based on indicators of infection following wild-caught tick challenge whereas most other types of vaccine are required to demonstrate protection from clinical signs of disease. In this vaccination-challenge study we sought to demonstrate the ability of a nonadjuvanted, outer surface protein A (OspA) vaccine to protect from infection and to prevent synovial lesions consistent with Borreliosis. Thirty, purpose-bred beagles were randomly divided into vaccinated and unvaccinated groups. The vaccinated group was administered two subcutaneous doses of a nonadjuvanted, purified, Borrelia burgdorferi OspA vaccine at a 21- day interval. Dogs were challenged by wild-caught, B. burgdorferi-infected ticks (Ixodes scapularis). Clinical signs, serology, Borrelia isolation and PCR evaluated antemortem vaccine efficacy. Postmortem histopathological analysis of synovial tissue was compared to antemortem infection status. Borreliosis was demonstrated by Borrelia isolation from skin biopsies in 13 out of 15 unvaccinated dogs. All unvaccinated dogs' Western blot profiles were consistent with infection. Two of 15 vaccinated dogs had at least one positive spirochete culture which cleared 91days post-challenge, and Western blot profiles were consistent with vaccination alone. No dogs, vaccinated or unvaccinated, exhibited clinical signs consistent with borreliosis. Based on a histopathological cumulative joint scoring system (CJS), all unvaccinated dogs had synovial lesions indicative of Lyme disease. Only one of the vaccinated dogs had a CJS that was greater than the statistical cut off score for the absence of synovial lesions. There was high correlation between clinical histopathology and spirochete isolation. Infection with B burgdorferi may produce inconsistent clinical signs of lameness. Histopathological changes in joints from infected dogs are reliable indicators of borreliosis and correlate well with other indicators of infection. This model provides support that vaccination with a nonadjuvanted, purified OspA vaccine offers protection from Borrelia infection and the resulting synovial lesions that can lead to clinical signs of lameness. PMID- 27692093 TI - Multinucleated giant cell cytokine expression in pulmonary granulomas of cattle experimentally infected with Mycobacterium bovis. AB - Regardless of host, pathogenic mycobacteria of the Mycobacterium tuberculosis complex such as Mycobacterium bovis, induce a characteristic lesion known as a granuloma, tubercle or tuberculoid granuloma. Granulomas represent a distinct host response to chronic antigenic stimuli, such as foreign bodies, certain bacterial components, or persistent pathogens such as M. bovis. Granulomas are composed of specific cell types including epithelioid macrophages, lymphocytes and a morphologically distinctive cell type, the multinucleated giant cell. Multinucleated giant cells are formed by the fusion of multiple macrophages; however, their function remains unclear. In humans, giant cells in tuberculous granulomas have been shown to express various cytokines, chemokines and enzymes important to the formation and maintenance of the granuloma. The objective of this study was to quantitatively assess multinucleated giant cell cytokine expression in bovine tuberculoid granulomas; focusing on cytokines of suspected relevance to bovine tuberculosis. Using calves experimentally infected with M. bovis, in situ cytokine expression was quantitatively assessed using RNAScope(r) for the following cytokines TNF-alpha, IFN-gamma, TGF-beta, IL-17A and IL-10. Multinucleated giant cells in bovine tuberculoid granulomas expressed all examined cytokines to varying degrees, with differential expression of TGF-beta, IL-17A and IL-10 in giant cells from early versus late stage granulomas. There was a modest, positive correlation between the level of cytokine expression and cell size or number of nuclei. These results suggest that multinucleated giant cells are active participants within bovine tuberculoid granulomas, contributing to the cytokine milieu necessary to form and maintain granulomas. PMID- 27692094 TI - Macrophage effector responses of horses are influenced by expression of CD154. AB - Reactive intermediates contribute to innate immunity by providing phagocytes with a mechanism of defense against bacteria, viruses and parasites. To better characterize the role of CD154 in the production of reactive intermediates, we cloned and expressed recombinant equine CD154 (reqCD154) in Chinese Hamster Ovary (CHO). In co-culture experiments, CHO cells ectopically expressing reqCD154 elicited superoxide production in monocyte-derived macrophages (MDM). Collectively, our results indicate that regulation of CD154 expression plays a role in innate host defenses. PMID- 27692095 TI - Screening scFv antibodies against infectious bursal disease virus by co expression of antigen and antibody in the bacteria display system. AB - We have previously reported an antigen and antibody co-expression (AAC) technology to demonstrate the interaction between a known antigen and antibody. To validate the co-expression system for screening antibody libraries, a single chain fragment variable(scFv)antibody library was constructed from chickens immunized with the VP2 protein of infectious bursal disease virus (IBDV). The genes of both VP2 and scFv antibodies were inserted into the pBFD-Ab-Ag vector. The co-expression library was subjected to three rounds of screening by flow cytometry (FCM) using a polyclonal antibody against VP2 through a bacteria display system. We achieved enrichment of scFv specific for IBDV. 110 individual clones were initially selected and sequenced. Twenty clones were selected based on fluorescence intensity by FCM. The scFv antibodies were expressed by pET-27b in E.coli and purified. The specificity and affinity of the selected scFv antibodies were confirmed by western blotting assay and ELISA analysis. What's more, the neutralizing capacity was measured with IBDV-B87(100 TCID50) in vitro. Four scFvs (clone 8(1), Y8, L10 and L7) showed significant neutralizing capacity. Two of the four scFvs (clone 8(1) and Y8) demonstrated a higher neutralizing activity to IBDV-B87 and the titers were 16,384 and 8,192, respectively. The two scFvs had higher neutralizing capacity than those obtained in previous studies. We demonstrated that the AAC technology could be applied to screen antibody libraries without baiting antigen to make antibody screening process easier and obtain scFvs with higher neutralizing capacity. PMID- 27692096 TI - Haemophilus parasuis vaccines. AB - Glasser's disease, which is caused by Haemophilus parasuis, is a major threat to swine throughout the world. At present, the predominant method of controlling this disease is through vaccination with an inactivated vaccine, which has many limitations. For example, there is no available method to differentiate between infected and vaccinated animals. In addition, inactivated vaccines do not contain all of the virulent serovars that circulate in a region. Additionally, novel vaccines that address the shortcomings of inactivated vaccines are not available. Here, we summarize existing knowledge concerning H. parasuis vaccines, and provide some suggestions that may help to improve H. parasuis vaccines. PMID- 27692097 TI - Secretory immunoglobulin A and immunoglobulin G in horse saliva. AB - This study aimed to increase the knowledge on salivary antibodies in the horse since these constitute an important part of the immune defence of the oral cavity. For that purpose assays to detect horse immunoglobulin A (IgA) including secretory IgA (SIgA) were set up and the molecular weights of different components of the horse IgA system were estimated. Moreover, samples from 51 clinically healthy horses were tested for total SIgA and IgG amounts in saliva and relative IgG3/5 (IgG(T)) and IgG4/7 (IgGb) content were tested in serum and saliva. Results showed a mean concentration of 74MUg SIgA/ml horse saliva and that there was a large inter-individual variation in salivary SIgA concentration. For total IgG the mean concentration was approx. 5 times lower than that of SIgA, i.e. 20MUg IgG/ml saliva and the inter-individual variation was lower than that observed for SIgA. The saliva-serum ratio for IgG isotypes IgG3/5 and IgG4/7 was also assessed in the sampled horses and this analysis showed that the saliva serum ratio of IgG4/7 was in general approximately 4 times higher than that of IgG3/5. The large inter-individual variation in salivary SIgA levels observed for the normal healthy horses in the present study emphasises the need for a large number of observations when studying this parameter especially in a clinical setting. Moreover, our results also indicated that some of the salivary IgG does not originate from serum but may be produced locally. Thus, these results provide novel insight, and a base for further research, into salivary antibody responses of horses. PMID- 27692098 TI - Effects of choline treatment in concentrations of serum matrix metalloproteinases (MMPs), MMP tissue inhibitors (TIMPs) and immunoglobulins in an experimental model of canine sepsis. AB - The aim of the present study was to investigate effects of intravenous (i.v.) choline treatment on serum matrix metalloproteinases (MMP), MMP tissue inhibitors (TIMP) and immunoglobulins (Igs), and to determine if there were relations between serum MMPs/TIMPs and C-reactive protein (CRP) (as a marker of the acute phase response), immunoglobulin G and M (IgG and IgM) (as a maker of the Ig responses) and markers of organ damage such as muscular damage (creatine phosphokinase, [CPK]), liver damage (alanine aminotransferase [ALT]) and renal dysfunction (blood urea nitrogen [BUN] and creatinine, [Cr]) in dogs with endotoxemia. Healthy dogs (n=24) were randomized to Saline, Choline (C), Lipopolysaccharide (LPS), and LPS+C groups and received 0.9% NaCl (5mL/i.v.), choline chloride (20mg/kg/i.v.), LPS (0.02mg/kg/i.v.) and LPS (0.02mg/kg/i.v.) plus choline chloride (20mg/kg/i.v.), respectively. Serum MMPs and TIMPs concentrations were analyzed by commercial ELISA kits. MMP and TIMP increased at 1-48h (P<0.05), whereas IgG and IgM decreased at 24-48h in LPS group, compared to their baselines. Choline treatment reduced changes in serum MMPs, TIMPs and markers of organ damage, and prevented the hypoimmunoglobulinemia in LPS+C. MMPs and TIMPs were correlated positively (P<0.05) with serum CRP, CPK, ALT, BUN and Cr, but not with serum Igs. Our findings suggest that the serum MMPs, TIMPs and Igs are involved in the pathophysiology of endotoxemia, and MMPs and TIMPs are correlated with the acute phase reaction and multi-organ failure. In addition, we demonstrated a direct effect of choline administration in decreasing serum MMPs and TIMPs, and preserving serum Igs in the course of endotoxemia.

PMID- 27692101 TI - Application of calcium phosphates and fibronectin as complementary treatment for osteoporotic bone fractures. AB - INTRODUCTION: The gradual aging of the population results in increased incidence of osteoporotic bone fractures. In a good quality bone, the fixation with the usual methods is adequate, but not in osteoporotic bone, in which consolidation delays and other complications are common, with failure rates for screws up to 25%. OBJECTIVE: To test fibronectin loaded hydroxyapatite as a complementary treatment for osteoporotic fractures. MATERIAL AND METHODS: This study was performed in a vivo model; 42 female osteoporotic adult rabbits 4-5kg (White New Zealand) were used. Two groups (hydroxyapatite and fibronectin loaded hydroxyapatite) and a control group were tested. 3 time points 24h, 48h and 5days were studied. Defects were created in both femurs, in one of them, a cannulated screw (4mm) and a biocompatible material were placed; in the other femur a screw was inserted without supplemented material forming the control group. Osteoporosis was induced from models already known throughout administration of steroids. Samples were analyzed histologically and through imaging (micro Ct). RESULTS: Basal levels of BMD are observed below to normal when compared to other studies (0.25/0.3 instead of 0.4). Global and dependent of time analysis of samples, show no significant differences for samples analyzed. However, an important trend was noted for variables that define the trabecular bone microarchitecture. Indices that define trabecular microarchitecture in the comparative analysis found to have statistical differences (p<0.01). DISCUSSION: Osteosynthesis in an osteoporotic bone is a challenge for the surgeon, due to a reduced bone mineral density and different bone architecture. The main finding was the verification of the hypothesis that the trabecular bone parameters increases with our augmentation material in weak rabbit bone quality. Also, the histological analyses of samples show an increase of non inflammatory cells in protein samples (OHAp-Fn) from the first 24hours. CONCLUSION: An early response of rabbit osteroporotic bone to a complementary treatment with fibronectin loaded hydroxyapatite has been observed. This response is reflected in greater values for indices that define the trabecular bone microarchitecture, thickness and separation, a greater non-inflammatory cellularity after only 24hours and an increased amount of connective tissue observed at 48hours. PMID- 27692102 TI - Minimally invasive polyaxial locking plate osteosynthesis for 3-4 part proximal humeral fractures: our institutional experience. AB - INTRODUCTION: The objectives of this study were to describe the surgical technique of fixation of 3-4 part proximal humeral fractures with polyaxial locking plates utilising a minimally invasive approach and to evaluate the accuracy of reduction and stability of fixation. PATIENTS AND METHODS: We retrospectively reviewed 90 patients. Fractures were classified according to the Neer classification system. Different radiological parameters were measured to assess the quality of reduction and the stability of fixation. Complications and clinical outcomes were evaluated after one year of minimum follow up. RESULTS: There were 76 women and 14 men, with a mean age of 67.4years +/-13 (range, 29 85). There were 60 3-part and 30 4-part fractures. Frozen cancellous allograft was used in 30 cases (33.3%). All fractures progressed to union and at one year follow up, the mean Constant score was 79.6+/-12(range, 62-100). Mean forward flexion, abduction, external rotation and internal rotation were 155 degrees , 148 degrees , 39 degrees and vertebra Dorsal 8, respectively. Complications were noted in seven patients while the postoperative "head-diaphysis angle", "greater tuberosity height" and "medial metaphysis reconstruction" were close to the anatomical parameters; no significant differences were noted at one year radiological follow up. CONCLUSION: Reliable and stable fixation can be expected with the use of polyaxial locking plate through a minimally invasive approach for the treatment of 3-4 part proximal humeral fractures. Satisfactory functional results for this procedure can be obtained. PMID- 27692104 TI - Effect of cefazolin and cefuroxime on fracture healing in rats. AB - OBJECTIVE: To determine the effect of cefazolin and cefuroxime (the two most commonly used beta lactam antibiotics) at therapeutic doses in fracture healing in an animal model. MATERIAL AND METHODS: 75 adult male wistar rats (3months old) were selected. They were divided into three groups of 25 animals each (placebo, cefazolin and cefuroxime). A closed fracture was made in the middle third of the right femur of each rat and fixed with a Kirschner wire. Each group was treated with either saline (placebo), cefazolin or cefuroxime at therapeutic doses during fracture healing. Four weeks after fracture rats were killed and femora analysed through mechanical and histological testing. RESULTS: The group treated with cefuroxime showed a lower mechanical resistance of the healing callus and a lower histological grade than placebo. The group treated with cefazoline showed a similar mechanical resistance and histological grade of callus to placebo. CONCLUSION: Cefuroxime appear to disturb fracture healing more than cefazolin or placebo in Wistar rats. If those results are similar to human, the use of cefuroxime during fracture healing should be avoided in the clinical setting, if possible. PMID- 27692103 TI - Comminuted fractures of the radial head: resection or prosthesis? AB - INTRODUCTION: At present, surgical treatment of comminuted radial head fractures without associated instability continues to be controversial. When anatomical reconstruction is not possible, radial head excision is performed. However, the appearance of long-term complications with this technique, along with the development of new radial head implants situates arthroplasty as a promising surgical alternative. The purpose of the present study was to compare the mid term functional outcomes of both techniques. MATERIALS AND METHODS: A retrospective study was performed between 2002 and 2011 on 25 Mason type-III fractures, 11 patients treated with primary radial head resection and 14 who received treatment of the fracture with metal prosthesis. At the end of follow up, patients were contacted and outcomes evaluated according to: Mayo Elbow Performance Score (MEPS), the Disabilities of the Arm, Shoulder and Hand score (DASH) and strength measurement. Radiographic assessment (proximal migration of the radius, osteoarthritic changes, and signs of prosthesis loosening) was also performed. RESULTS: The average age of the sample was 53.7 years in the resection group, and 54.4 years in the replacement group, with a mean follow-up of 60.3 and 42 months respectively. According to the MEPS scale, there were 6 excellent cases, 3 good and 2 acceptable in the resection group, and 6 excellent cases, 3 good, 3 acceptable, and 2 poor in the prosthesis group. The mean DASH score were 13.5, and 24.8 for the resection and the replacement group respectively. We found one postoperative complication in the resection group (stiffness and valgus instability) and 6 in the replacement group: 3 of joint stiffness, 1 case of prosthesis breakage, and 2 neurological injuries. CONCLUSIONS: Although this is a retrospective study, the high complication rate occurring after radial head replacement in comparison with radial head resection, as well as good functional results obtained with this last technique, leads us to recommend it for comminuted radial head fractures without associated instability. PMID- 27692105 TI - Large fracture of the anteromedial tibial plateau with isolated posterolateral knee corner injury: case series of an often missed unusual injury pattern. AB - Tibial plateau fractures are a heterogeneous group of lesions with multiple fracture patterns. They are often associated with soft tissue injuries, the lateral meniscus and the anterior cruciate ligament (ACL) being the most common structures affected. The purpose of this article is to present a case series of an often missed unusual injury pattern that consists on the association of a large anteromedial tibial plateau fracture with a posterolateral (PL) knee corner injury without involvement of the cruciate ligaments. The diagnosis of PL complex injury may go unrecognized in a considerable number of cases and delay on the treatment decreases the success rate of soft tissue repairing. The importance of a high index of suspicion and a proper early diagnosis with an MRI is of paramount importance. We also describe the current surgical management used by the authors and review of the current literature. PMID- 27692106 TI - Whole-exome sequencing analysis in twin sibling males with an anterior cruciate ligament rupture. AB - Familial predisposition is among the major genetic risk factors for non-contact musculoskeletal tissue injuries. Personal genome sequence shows that different polymorphism profiles may account for the number and the degree of injuries and the recovery time. Genotyping studies allow investigation into genome factors with potential impact on pathogenesis of non-contact ligament injuries. We have studied a family with twin sibling males surgically diagnosed of an anterior cruciate ligament non-contact rupture and non-affected progenitors (father and mother) were subjected to whole exome sequencing (WES) analysis. WES analysis previously carried out on 16 individuals, without ACL injury medical records, were also included in this study for single nucleotide variants (SNVs) and small insertions and deletions detection (indels), variant filtering and to prioritize variants relative to the disease. WES analysis to identify SNVs and indels was performed using open web-based bioinformatics tools. A set of 11 new variants shared by family members can be associated to ACL non-contact injury, including SerpinA11, ARSI, NOCHT4, EPB41, FDFT1, POMC, KIF26A, OLFML2B, ATG7, FAH and WDR6. All of them, except ATG7 and WDR6, have shown a damaging predictive pattern by combinatorial standard predictive scores. In combination to the identified SNVs of EPB41 and SerpinA11 genes, ACTL7A gene showed a predicted deleterious variant reinforcing the idea these variants impact on of fibroblast-like cells deformability and ECM misbalance, Differential gene expression and RNA sequencing analysis will help to understand the combined participation of these protein coding genes in ACL non-contact injuries. PMID- 27692107 TI - Predictive variables of open reduction in intertrochanteric fracture nailing: a report of 210 cases. AB - BACKGROUND: Factors that impede closed reduction in intertrochanteric fractures remain unknown. This study was designed with the aim of establishing radiological variables that can predict an open reduction when nailing those type of fractures. MATERIALS AND METHODS: Observational prospective study carried out between March 2013 and March 2015. Patients of both gender who suffered an intertrochanteric fracture, and who were surgically treated by intramedullary nailing (PFN-A), were included. Patients were evaluated by means of a questionnaire designed in 12 de Octubre Trauma department. Radiological parameters assessed preoperatively, after fracture reduction in the traction table, and after fixation were: calcar, lateral wall and posterior buttress integrity or disruption; lesser trochanter location, varus or valgus deformities, and flexion or extension of the proximal fragment. RESULTS: Association between open reduction and the following types of fractures was statistically significant (p<0.001): subtypes A2.3, A3.2 and A3.3 of AO classification and subtypes IV and V of Evans classification. There were four radiological parameters associated with the need for open reduction: disruption of lateral wall (p<0.0000), posterior wall fracture (p<0.001), calcar (p<0.004) and malalignment in the axial view (p<0.001). CONCLUSIONS: Open reduction seems to be necessary for complex fracture patterns such as A2.3, A3.2 and A3.3 types of AO/OTA classification, as well as types IV and V of Evans classification. There are four major radiological parameters that can predict the need of approaching the fracture site: posterior buttress, calcar disruption, lateral wall disruption and proximal fragment flexion. The development of high quality evidence regarding this topic is necessary due to the vast impact that open reduction can have on elderly patients. PMID- 27692108 TI - Surgical delay as a risk factor for wound infection after a hip fracture. AB - PURPOSE: Analysis of significant risk factors for mortality and for medical and orthopaedic complications. PATIENTS AND METHODS: Observational study of a prospective consecutive cohort of 697 patients diagnosed of hip fracture from December 2012 to December 2014. Average age was 85+/-9years and 520 were female (75%). Intracapsular fractures (308, 44%) were treated non-operatively, (19 patients), with cannulated screws (58) or with hip arthroplasty (228 bipolar, 3 total hip atrhoplasty). Extracapsular fractures (389, 56%) were reduced and fixed with 375 trochanteric nails and 14 sliding-hip-screw-plates. Patients were controlled clinically and radiographically in outpatient clinic after 1, 3, 6 and 12months. Bivariate analysis (Pearson, Mann-Whitney, Wilcoxon) was applied to study statistically significant relations, and Odds Ratio were calculated. RESULTS: Surgical delay reached 2.1+/-2.2days, 1.7+/-1.9 in medically stable patients. Main reason for delay was anticoagulant/anti-platelet therapy. Immediate weight-bearing was begun for 72% of patients. Average time in-hospital was 12+/-8days and 63% returned to previous environment. Lost-to-follow-up reached 4% after 1month and 8% after 6months. After 1year, 6% of previously walking patients were unable to walk. Mortality reached 4% while in-hospital and 14% after 1year, with older age as only significant risk factor (p=0.004), OR=1.9. Wound infection developed in 2.3% of the series, and surgical delay longer than 24hours was a significant risk factor (p=0.023), with an OR=3.48 (1.1 10.8). Fixation failed in 7.9% of cannulated screws and 1.9% of trochanteric nails (1.1% cut-out, 0.8% nail fracture), while 2.7% of arthroplasty patients suffered a prosthesis dislocation and 1.3% a periprosthetic fracture. Pyelonephritis appeared in 6.7%, pneumonia in 6.3% and cardiac failure in 2.2% of patients; significant risk factors were previous comorbidity for pneumonia (p=0.007) (OR=2.7) and cardiac failure (p=0.007) (OR=9.7), as well as older age (p=0.006) (OR=2.2) for pneumonia. CONCLUSIONS: Surgical delay longer than 24hours has been an important risk factor for wound infection, a finding not previously described in literature. Older age is a significant risk factor for mortality and pneumonia, and previous comorbidity for cardiac failure and pneumonia. PMID- 27692110 TI - Necrotising fasciitis of the extremities: implementation of new management technologies. AB - INTRODUCTION: Necrotising fasciitis (NF) is potentially life-threatening soft tissue infection. Early diagnosis and aggressive surgical debridement are critical to decrease mortality and morbidity. The impacts of new management technologies such as hydro-bisturi-assisted debridement (HAD) and negative pressure wound therapy (NPWT) are not yet clear with respect to treatment of NF. The objective of this study was to describe laboratory (including LRINEC score), clinical and microbiological factors, treatment methods and outcomes related to managing necrotising fasciitis, focusing on the implementation of new treatment methods in our centre. METHODS: From June 2010 to June 2014, adult patients diagnosed with necrotising fasciitis affecting an upper or lower limb that were admitted to our hospital, a referral tertiary care centre, were eligible to participate in this study. Demographic data, clinical features, location of infection, Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC) score on the day of admission, microbiology and laboratory results, use of HAD, wound management using NPWT, and patient outcomes were retrospectively analysed. A univariate risk factor analysis was performed, in an attempt to define prognostic factors for mortality. RESULTS: A total of 20 patients satisfied the inclusion criteria. Type II NF (Group A beta-haemolytic streptococci) was found in 8 cases (40%). The average LRINEC score on the day of admission was 6. The lower extremity was affected in 60% of the cases. All patients were treated operatively, with 2.5 interventions on average. Hydro-bisturi was used in the first debridement in 40% of the cases (8 out 20). In 75% of the studied cases, Negative Pressure Wound Therapy (NPWT) was the technique selected for surgical wound management. The global mortality rate was 30%. On univariate analysis, the only factors significantly associated with mortality were high levels of creatinin (p=0.033) and low blood glucose levels (p=0.012). Finally, four amputations were observed in this series. CONCLUSION: We confirm that necrotising fasciitis (NF) of the extremities, despite new advancements in treatment and critical care management, is still a potentially life-threatening soft-tissue infection (30% mortality). New, advanced wound management modalities have been heavily used in management of necrotising fasciitis, but these have not had significant impacts on morbidity and mortality rates. PMID- 27692109 TI - Age-related injury patterns in Spanish trauma ICU patients. Results from the RETRAUCI. AB - BACKGROUND: Injury patterns may differ in trauma patients when age is considered. This information is relevant in the management of trauma patients and for planning preventive measures. METHODS: We included in the study all patients admitted for traumatic disease in the participating ICUs from November 23rd, 2012 to July 31st, 2015 with complete records. Data on epidemiology, injury patterns, severity scores, acute management, resources utilisation and outcome were recorded and compared in the following groups of age: <=55years (young adults), 56-65 years (adults), 66-75 years (elderly), >75years (very elderly). Quantitative data were reported as median (Interquartile Range (IQR) 25-75) and categorical data as number and percentage. Comparison between groups of age with quantitative variables was performed using the analysis of variance (ANOVA) test. Differences between groups with categorical variables were compared using the chi square test. A value of p<0.05 was considered significant. RESULTS: We included 2700 patients (78.9% male). Median age was 46 (31-62) years. Blunt trauma was present in 93.7% of the patients. Median RTS was 7.55 (5.97-7.84). Median ISS was 20 (13-26). High-energy trauma secondary to motor-vehicle accident with rhabdomyolysis and drugs abuse showed an inverse linear association with ageing, whilst pedestrian falls with isolated brain injury, being run-over and pre-injury antiplatelets or anticoagulant treatment increased with age (in all cases p<0.001). Multiple injuries were more common in young adults (p<0.001). Acute kidney injury prevalence was higher in elderly and very elderly patients (p<0.001). ICU Mortality increased with age in spite of similar severity scores in all groups (p<0.001). The main cause of death in all groups was intracranial hypertension. CONCLUSIONS: Different injury patterns exist in relation with ageing in trauma ICU patients. Adult patients were more likely to present high energy trauma with significant injuries in different areas whilst elderly patients were prone to low-energy falls, complicated by antiplatelets or anticoagulants use, resulting in severe brain injury and increased mortality. PMID- 27692111 TI - Histological evolution of the regenerate during bone transport: an experimental study in sheep. AB - INTRODUCTION: Bone transport (BT) for segmentary bone defects is a well-known technique as it enables correction with new bone formation, which is similar to the previous bone. Despite the high number of experimental studies of distraction osteogenesis in bone lengthening, the types of ossification and histological changes that occur in the regenerate of the bone transport process remain controversial. OBJECTIVE: The aim of this study is to provide the complete evolution of tissues and the types of ossification in the regenerate during the different phases of bone formation after BT until the end of the remodelling period. METHODS: A histological study was performed using ten adult sheep that were submitted to BT. The types of ossification as well as the evolution of different tissues in the regenerate were determined using histomorphometry and inmunohistochemical studies. The evolution of trabeculae thickness, osteoblast and osteoclast densities, relationship between collagen types and changes in vascularization were also studied. RESULTS: Ossification was primarily intramembranous, with some focus of endochondral ossification in isolated animals. The cell counts showed a progression of cellular activity from the periphery to the centre, presenting the same progression as the growth of bone trabeculae, whose trabeculae thickness was quadrupled at the end of remodelling. Inmunohistochemical studies confirmed the prevalence of type I collagen and the ratio of the Type I/Type II collagen ratio was found to be 2.48. The percentages of the vascularized areas were proximally higher than distally in all animals, but distal zone obtained higher rates than the central region. CONCLUSIONS: Bone transport regenerate exhibits a centripetal ossification model and a mixed pattern with predominance of intramembranous over endochondral ossification. The data obtained resemble partially to those found in models of bone lengthening applied to large animals. This study provides a detailed structural characterization of the newly formed tissue, which may help to explain the development of the regenerate of bone transport in humans. It will also serve for future mechanobiological models that may aid research on the effect of loading or distractor stiffness in clinical results. PMID- 27692112 TI - Is cannulated-screw fixation an alternative to plate osteosynthesis in open book fractures? A biomechanical analysis. AB - OBJECTIVES: The current biomechanical work compares the symphyseal and sacroiliac stability obtained with two systems of bone osteosynthesis. The two methods of fixation compared were the 6-hole suprapubic non-locked plate and pubic fixation with two cannulated screws, a novel technique that can be applied percutaneously in the clinical practice. The aim of this study was to examine the validity of the use of two-cannulated-screws osteosynthesis in order to minimize the secondary effects of open fixation, especially in patients in whom an open reduction is contraindicated. MATERIALS AND METHODS: A biomechanical study was designed in 9 fresh, human pelvis specimens, simulating an AO B1.1 type injury, using both fixation systems sequentially in each specimen. In both parts of the test, the specimens were subjected to an axial load of 300N. Displacements and rotations between the different pelvic elements were studied by means of a discrete set of points. The absence of differences between the two systems has been set as the null hypothesis. RESULTS: There were significant differences in favor of the cross-cannulated screws in most of the displacements measured at the pubic symphysis and sacroiliac joint. CONCLUSIONS: Fixation of the AO B1.1 type fractures with cross cannulated screws restores the biomechanical behavior of the pubic symphysis, obtaining better stability than fixation with the 6-hole non locked plate. To date, no comparative, biomechanical studies have been conducted with these two systems of osteosynthesis. This study demonstrates that cross cannulated screws fixation of the pubic symphysis in AO B1.1 pelvic fractures should be considered as an alternative to the conventional plating system. PMID- 27692113 TI - Allograft plus OP-1 enhances ossification in posterolateral lumbar fusion: A seven year follow-up. AB - PURPOSE: To study the results of the combination of allograft plus BMP-7 in comparison with allograft alone in posterolateral lumbar arthrodesis. PATIENTS AND METHODS: A blinded controlled consecutive prospective cohort of skeletally mature patients study. One hundred and ten patients underwent posterolateral lumbar instrumented arthrodesis. Allograft randomly compacted onto either the right or the left side of the articular and the posterior aspect of the transverse processes of lumbar spine. The same procedure performed on the contralateral side, but allograft was previously mixed with osteogenic protein (OP-1). Clinical, x-ray and CT-scan long follow-up performed. Univariable and multivariable logistic regression analyses. RESULTS: More bone continuity was found with allograft plus OP-1 than with allograft alone (p>0.0038). The amount of bone mass was greater on the OP-1 side (p<0.001). No local or systemic adverse effect were noted. CONCLUSIONS: Allograft on one side plus allograft with BMP-7 on the other achieved a fusion rate of 93 per cent. Allograft combined with BMP-7 was more effective than allograft alone.

PMID- 27692116 TI - Ensuring Cardiac Rehabilitation Access for the Majority of Those in Need: A Call to Action for Canada. AB - Cardiac rehabilitation (CR) is a proven model of secondary prevention. Indicated cardiac conditions for CR are well established, and participation of these patients results in significantly lower mortality and morbidity when compared with usual care. There are approximately 170 CR programs in Canada, which varies widely by province. There is a grossly insufficient capacity to treat all patients with cardiac indications in Canada and beyond. The density of CR services is about half that in the United States, at 1 program per 208,823 inhabitants or 1 program per 7779 patients with cardiac disease. Despite the Canadian Cardiovascular Society's target of 85% referral for CR for cardiac inpatients with the appropriate indications, significantly fewer patients are referred for CR. Moreover, certain patient groups-such as women, ethnocultural minorities, and those of low socioeconomic status-are less likely to access CR, despite greater need because of poorer outcomes. CR appears to be reaching a healthier population that is perhaps more adherent to secondary prevention recommendations and hence in less need of the limited CR spots available. The reasons for CR underuse are well established and include factors at patient, referring provider, CR program, and health system levels. A Cochrane review has established some effective interventions to increase CR use, and these must be implemented more broadly. We must advocate for CR reimbursement. Finally, we must reallocate our CR resources to patients with the greatest need. This may involve risk stratification, with subsequent allocation of lower-risk patients to a more widely available, lower-cost, and effective alternative model of CR. PMID- 27692117 TI - Impact of Cardiac Rehabilitation and Exercise Training on Psychological Risk Factors and Subsequent Prognosis in Patients With Cardiovascular Disease. AB - The role of psychological risk factors has been under-recognized in most subspecialties of medicine, as well as in general medicine practices. However, considerable evidence indicates that psychosocial factors are involved in the pathogenesis and progression of cardiovascular disease (CVD). Emerging data from cardiac rehabilitation (CR) settings and CR exercise training (CRET) programs have demonstrated the value of comprehensive CRET to improve psychological functioning and reduce all-cause mortality. Recent evidence also supports the role of CRET and the added value of stress management training in the secondary prevention of CVD. PMID- 27692115 TI - Comprehensive Cardiovascular Risk Reduction and Cardiac Rehabilitation in Diabetes and the Metabolic Syndrome. AB - The epidemic of obesity has contributed to a growing burden of metabolic syndrome (MetS) and diabetes mellitus (DM) worldwide. MetS is defined as central obesity along with associated factors such as hypertriglyceridemia, low high-density lipoprotein cholesterol, hyperglycemia, and hypertension. MetS and DM are associated with significant cardiovascular morbidity and mortality. Healthy behavioural modification is the cornerstone for reducing the atherosclerotic cardiovascular disease burden in this population. Comprehensive, multidisciplinary cardiac rehabilitation (CR) programs reduce mortality and hospitalizations in patients with MetS and DM. Despite this benefit, patients with MetS and DM are less likely to attend and complete CR because of numerous barriers. Implementation of innovative CR delivery models might improve utilization of CR and cardiovascular outcomes in this high-risk population. PMID- 27692119 TI - Heart Failure: Exercise-Based Cardiac Rehabilitation: Who, When, and How Intense? AB - The primary chronic symptom in patients with clinically stable heart failure (HF) is reduced exercise tolerance, measured as decreased peak aerobic power (peak oxygen consumption [Vo2]), and is associated with reduced quality of life and survival. Exercise-based cardiac rehabilitation (EBCR) is a safe and effective intervention to improve peak Vo2, muscle strength, physical functional performance, and quality of life and is associated with a reduction in overall and HF-specific hospitalization in clinically stable patients with HF. Despite these salient benefits, fewer than one-tenth of eligible patients with HF are referred for EBCR after hospitalization. In this review, selection for and timing of EBCR for patients with HF, as well as exercise prescription guidelines with special emphasis on the optimal exercise training intensity to improve peak Vo2, are discussed. PMID- 27692118 TI - Rehabilitation Therapy in Peripheral Arterial Disease. AB - Peripheral arterial disease (PAD) is the result of atherosclerosis in the lower limb arteries, which can give rise to intermittent claudication (IC), limb ulceration, infections, and, in some circumstances, amputation. As a result of PAD, patients are frequently limited in both walking duration and speed. These ambulatory deficits impact both functional capacity and quality of life. The prevalence of PAD is increasing, and patients with this diagnosis have high cardiovascular morbidity and mortality. A comprehensive approach is required to improve outcomes in patients with PAD and include tobacco cessation, pharmacologic management of metabolic fitness, risk-factor modification, and exercise training. Supervised exercise programs significantly improve functional capacity and quality of life in addition to reducing IC. These programs reduce morbidity and mortality and are cost-effective; yet they are uncommonly prescribed. Supervised exercise training is an accepted intervention in the PAD population and has been included in both Canadian and American guidelines for PAD management. This review describes (1) key background information related to PAD, (2) the initial approach to PAD diagnosis, (3) pharmacologic management options, (4) risk-factor modification, and (5) the currently accepted approach to exercise training. Key recommendations for enhancing PAD care in a Canadian context are also discussed.

PMID- 27692121 TI - Effect of Cardiac Rehabilitation on South Asian Individuals With Cardiovascular Disease: Results From the APPROACH Registry. AB - BACKGROUND: Unequivocally, cardiac rehabilitation (CR) in patients with established cardiovascular disease improves survival. However, its effect on higher-risk ethnic groups has not been explored. Accordingly, we evaluated the effect of CR on South Asian (SA) compared with European Canadians with coronary artery disease (CAD). METHODS: Using the Alberta Provincial Project for Outcome Assessment in Coronary Heart Disease (APPROACH) registry, 26,167 patients from Edmonton, Alberta who received coronary angiography with documented CAD were reviewed (January 2002 to March 2012). After excluding Chinese patients, 1027 SA patients were compared with 11,992 European Canadian patients using validated surname algorithms. Adjustment was performed using a Cox proportional hazard model. RESULTS: Of the SA cohort, 50.6% attended CR, compared with 43.0% of the European Canadian cohort (P < 0.001). After adjustment, CR was associated with long-term survival irrespective of ethnic group (total study population: hazard ratio [HR], 0.57; 95% confidence interval [CI], 0.52-0.63; P < 0.001; SA population: HR, 0.63; 95% CI, 0.40-0.99; P = 0.045; European population: HR, 0.57; 95% CI, 0.52-0.63; P < 0.001). When comparing SA vs European Canadians attending CR, improved survival was observed in SA patients (HR, 0.58; 95% CI, 0.40-0.85; P < 0.001). This benefit appeared limited to SA patients who completed CR (complete CR: HR, 0.37; 95% CI, 0.17-0.85; P = 0.02; incomplete CR: HR, 0.78; 95% CI, 0.45-1.35; P = 0.38). CONCLUSIONS: Overall, referral rates to CR remains low but attendance appears higher in SA patients. Among those who attended CR, there is a strong association with improved survival irrespective of ethnic status. In SA patients with CAD, attendance and completion of CR should be strongly endorsed because of its incremental benefit. PMID- 27692122 TI - Foreword.

PMID- 27692124 TI - Effectiveness and Factors Determining the Success of Management Programs for Patients With Heart Failure: A Systematic Review and Meta-analysis. AB - INTRODUCTION AND OBJECTIVES: Heart failure management programs reduce hospitalizations. Some studies also show reduced mortality. The determinants of program success are unknown. The aim of the present study was to update our understanding of the reductions in mortality and readmissions produced by these programs, elucidate their components, and identify the factors determining program success. METHODS: Systematic literature review (1990-2014; PubMed, EMBASE, CINAHL, Cochrane Library) and manual search of relevant journals. The studies were selected by 3 independent reviewers. Methodological quality was evaluated in a blinded manner by an external researcher (Jadad scale). These results were pooled using random effects models. Heterogeneity was evaluated with the I2 statistic, and its explanatory factors were determined using metaregression analysis. RESULTS: Of the 3914 studies identified, 66 randomized controlled clinical trials were selected (18 countries, 13 535 patients). We determined the relative risks to be 0.88 for death (95% confidence interval [95%CI], 0.81-0.96; P < .002; I2, 6.1%), 0.92 for all-cause readmissions (95%CI, 0.86-0.98; P < .011; I2, 58.7%), and 0.80 for heart failure readmissions (95%CI, 0.71-0.90; P < .0001; I2, 52.7%). Factors associated with program success were implementation after 2001, program location outside the United States, greater baseline use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, a higher number of intervention team members and components, specialized heart failure cardiologists and nurses, protocol-driven education and its assessment, self-monitoring of signs and symptoms, detection of deterioration, flexible diuretic regimen, early care-seeking among patients and prompt health care response, psychosocial intervention, professional coordination, and program duration. CONCLUSIONS: We confirm the reductions in mortality and readmissions with heart failure management programs. Their success is associated with various structural and intervention variables.

PMID- 27692128 TI - Step-down treatment from medium-dosage of budesonide/formoterol in controlled asthma. AB - BACKGROUND: The stepping down of asthma treatment can be considered when asthma symptoms have been well controlled with inhaled corticosteroids (ICSs)/long acting beta2 adrenergic agonists (LABAs). However, few data are available comparing the efficacy between two step-down strategies, to reduce ICS/LABA dose or to withdraw LABA continuing ICS, in well-controlled asthmatics. METHODS: This was a prospective multicentre randomized, two-arm, controlled study. Ninety-one asthmatic patients controlled by budesonide/formoterol combination (BFC) 320/9 MUg twice daily were assigned to 2 stepping-down treatments as follows: the BFC group; BUD/FM 160/4.5 MUg twice daily, and the ICS group; ICS (budesonide 400 MUg twice daily or equivalent dose of ICS) without LABA, and followed for 12 weeks. The primary outcome was the incidence of asthma exacerbations. Asthma control, pulmonary function tests, and fraction of exhaled nitric oxide (FeNO) were evaluated at the beginning and end of the period. RESULTS: The incidence of exacerbations was 16.3% in the BFC groups and 12.5% in the ICS group, which were not different between the groups (p = 0.766). No significant differences were found in QOL score and FeNO between 0 week and 12 week in the both group. FEV1 and FEV1 percentage of the predicted value were lower at week 12 than at week 0 in the ICS group, but not in the BFC group. CONCLUSIONS: The two step-down strategies for 12 weeks have equal acceptability in well-controlled asthmatics treated with medium-dose of BFC, however, withdrawal of LABA may have potential risk to deteriorate FEV1.

PMID- 27692129 TI - Impact of asthma on mortality in older women: An Australian cohort study of 10,413 women. AB - BACKGROUND: Comorbid conditions frequently coexist with asthma in older adults and can alter the natural history of asthma, complicating management and affecting overall prognosis and survival. OBJECTIVES: This study investigates the impact of asthma on mortality among older women, with a specific interest in influence of comorbidities and social factors on survival of older women with asthma. DESIGN: Participants were from the Australian Longitudinal Study on Women's Health and were born between 1921 and 1926. Cox proportional hazards were used to evaluate mortality rates for women with and without asthma, after adjustment for comorbidities and other factors. RESULTS: Of 10,413 women aged 73 78, 829 (8%) reported having been diagnosed by a doctor for asthma. Women with asthma had a higher likelihood of heart disease, hypertension, thrombosis, bronchitis/emphysema, osteoporosis and major illnesses (p < 0.0001). Asthma was associated with increased risk of death (HR = 1.31, 95%CI 1.18-1.45, p < 0.0001). After adjusting for age, demographic factors, comorbidities, risk factors, residential area and social support, women with asthma retained a 17% increased risk of death compared to women without asthma (HR = 1.17, 95%CI 1.03-1.32, p = 0.016). CONCLUSION: Older women with asthma have a higher rate of mortality compared with other women of the same age. This increased risk of death remains after age, demographic factors, comorbidities, risk factors, residential area and social support have been taken into account. PMID- 27692130 TI - Factors associated with pulmonary hypertension and long-term survival in bronchiectasis subjects. AB - BACKGROUND: The development of pulmonary hypertension (PH) and its effect on long term survival in bronchiectasis subjects has not been explored. The present study aims to analyze the factors associated with PH and its effect on long-term survival in bronchiectasis subjects. METHODS: We prospectively evaluated 23 bronchiectasis subjects without PH and 16 with PH, as well as 20 healthy volunteers. RESULTS: Bronchiectasis subjects with PH were more hypoxemic and had a greater number of involved lobes in high resolution computed tomography (HRCT) than did the bronchiectasis subjects without PH (P < 0.001 and P < 0.001, respectively). At three years, the survival rate was 95.7% for bronchiectasis subjects without PH and 56.3% for bronchiectasis with PH, and at 5 years, these rates were 95.7% and 62.5%, respectively (P = 0.002). Multivariate Cox regression analysis revealed that only the Medical Research Council (MRC) dyspnea score was independently related to poor survival in all bronchiectasis subjects (hazard ratio: 6.98; 95% CI: 2.41-20.23; P < 0.00001). CONCLUSIONS: Subjects with PH are more hypoxemic and have a greater number of involvements in the lobes of the lungs. Bronchiectasis subjects with PH have worse survival than do bronchiectasis subjects without PH. MRC dyspnea score is an independent predictor of long-term survival. PMID- 27692132 TI - Ethnic and socio-economic differences in the prevalence of wheeze, severe wheeze, asthma, eczema and medication usage at 4 years of age: Findings from the Born in Bradford birth cohort. AB - BACKGROUND: Asthma, wheeze and eczema are common in early childhood and cause considerable morbidity. Generally rates of these conditions are higher in high income compared to low income countries. Rates in developed nations are generally higher than in less developed countries. After migration to Western countries, differences in risks of developing these conditions may between migrant and non migrant may diminish. METHODS: A convenience sample of 1648 children of White British, Pakistani or Other ethnicity aged between 4 and 5 years were recruited from the main Born in Bradford cohort. Children's parents or guardians were asked to report on a range of potential risk factors and their associations with wheeze, asthma and eczema. Relationships between ethnicity and disease outcomes were examined using logistic regression after adjustment for other relevant risk factors and confounders. RESULTS: Ethnic differences in doctor diagnosed asthma were evident, with children of other ethnic Origin being less likely and children of Pakistani origin more likely to have a diagnosis than White British or other origin children, although after adjustment for other risk factors this difference only remained significant for the Other Ethnic group. Ethnic differences were not observed in other outcomes including wheeze in the past 12 months, severe wheeze and taking medications for breathing problems. CONCLUSIONS: In UK born children, traditional risk factors such as gender, family history, socio-economic status and child's medical history may be stronger risk factors than ethnicity or familial migration patterns. PMID- 27692131 TI - Randomised, double-blind, placebo-controlled, cross-over single dose study of the bronchodilator duration of action of combination fluticasone furoate/vilanterol inhaler in adult asthma. AB - BACKGROUND: Fluticasone furoate (FF)/vilanterol (VI) is a once-daily maintenance treatment for asthma and chronic obstructive pulmonary disease. The duration of bronchodilation beyond 24 h has not been determined previously. METHODS: Adults aged 18-65 (n = 32), with asthma and reversibility to salbutamol (>=15% and >=200 mL increase in forced expiratory volume in 1 s [FEV1]) participated in a double blind, placebo-controlled, crossover study. Patients were admitted to a clinical trials unit for 72 h, and inhaled, in random order, placebo or FF/VI 100/25 mcg via ELLIPTA dry powder inhaler on two occasions 7-14 days apart. FEV1 was measured at baseline, 15 and 30 min, 1, 2, 4, 12, 24, 36, 48, 60, and 72 h. The differences in change in FEV1 from baseline between treatments and corresponding two-sided 95% confidence intervals (CI) were calculated at each time point. FINDINGS: FF/VI produced a rapid onset of bronchodilation (adjusted mean difference in change from baseline in FEV1 versus placebo at 15 min, 252 mL [95% CI 182-322]). Maximum bronchodilation was observed at 12 h (adjusted mean difference in the change from baseline in FEV1, 383 mL [95% CI 285-481]). Bronchodilation was maintained throughout the 72-h assessment period (adjusted mean difference in the change in FEV1 from baseline at 72 h, 108 mL (95% CI 15 200]). FF/VI was well tolerated and no serious side effects were reported. INTERPRETATION: A single dose of FF/VI 100/25 mcg showed evidence of a 72-h bronchodilator duration of action in adults with asthma. PMID- 27692133 TI - Characterization of bronchiectasis in the elderly. AB - INTRODUCTION: Although bronchiectasis particularly affects people >=65 years of age, data describing clinical characteristics of the disease in this population are lacking. This study aimed at evaluating bronchiectasis features in older adults and elderly, along with their clinical outcomes. METHODS: This was a secondary analysis of six European databases of prospectively enrolled adult outpatients with bronchiectasis. Bronchiectasis characteristics were compared across three study groups: younger adults (18-65 years), older adults (66-75 years), and elderly (and >=76 years). 3-year mortality was the primary study outcome. RESULTS: Among 1258 patients enrolled (median age: 66 years; 42.5% males), 50.9% were >=65 years and 19.1 >= 75 years old. Elderly patients were more comorbid, had worse quality of life and died more frequently than the others. Differences were detected among the three study groups with regard to neither the etiology nor the severity of bronchiectasis, nor the prevalence of chronic infection with P. aeruginosa. In multivariate regression model, age (OR: 1.05; p-value: <0.0001), low BMI (OR: 2.63; p-value: 0.02), previous hospitalizations (OR: 2.06; p-value: 0.006), and decreasing FEV1 (OR: 1.02; p value: 0.001) were independent predictors of 3-year mortality, after adjustment for covariates. CONCLUSION: Bronchiectasis does not substantially differ across age groups. Poor outcomes in elderly patients with bronchiectasis might be directly related to individual's frailty that should be further investigated in clinical studies. PMID- 27692134 TI - Efficacy of nasal continuous positive airway pressure on patients with OSA with erectile dysfunction and low sex hormone levels. AB - PURPOSE: This study aimed to test the hypothesis that erectile dysfunction (ED) is common in men with obstructive sleep apnea (OSA). We also assessed the efficacy of continuous positive airway pressure (CPAP) treatment for ED and sex hormone levels in patients with severe OSA and ED. METHODS: A total of 153 OSA patients and 60 healthy controls were enrolled in this study. The International Index of Erectile Dysfunction-5 (IIEF-5) score was obtained, and blood samples were collected for analysis of sex hormones after polysomnography. The IIEF-5 score, sex hormone levels, and polysomnographic parameters were re-evaluated in 32 patients with severe OSA and ED after 1 month of CPAP treatment. RESULTS: The present study showed that the prevalence of ED was 47.1% in all cases and only 13.3% in controls, and a lower sex hormone levels was presented in OSA patients. OSA patients with ED had greater severity of disease, and lower serum levels of follicle stimulating hormone (FSH) and testosterone than OSA patients without ED (p < 0.05). After CPAP therapy, there was a significant increase in the IIEF-5 score, and serum levels of FSH, luteinizing hormone, and testosterone, were elevated compared with baseline levels (p < 0.05). Multivariate regression analysis indicated the serum level of testosterone had impact on the ED. CONCLUSIONS: OSA patients had lower sex hormone levels and a higher occurrence of ED than controls, and serum level of testosterone had effect on ED. CPAP treatment ameliorated the symptoms of ED and elevated serum levels of FSH, luteinizing hormone, and testosterone. PMID- 27692135 TI - Evaluation of Chronic Obstructive Pulmonary Disease (COPD) and reduced ejection fraction heart failure (HFrEF) discharge medication prescribing: Is drug therapy concordant with national guidelines associated with a reduction in 30-day readmissions? AB - INTRODUCTION: Approximately 1 in 5 hospitalized COPD patients are readmitted within 30 days of discharge. CHF coexists in more than 20% of patients with COPD, and is associated with early readmission for COPD. Reducing 30-day hospital readmissions for COPD is of intense current interest. METHODOLOGY: A retrospective chart review was performed to identify patients discharged with COPD exacerbation and HFrEF. The primary objective was to evaluate if discharge medication prescribing following guidelines for both COPD and HFrEF correlates with reduced 30-day readmission rates. RESULTS: The study included 281 admissions with 39.1% prescribed appropriate discharge medications for both COPD and HFrEF; 30-day readmission rate was 24.5% for these patients compared to 31.1% that were not prescribed appropriate medications (p = 0.24). Beta blockers, ACE inhibitors or ARBS, and aldosterone antagonists were under-prescribed, but this did not significantly associate with increased readmission (p = 0.51, p = 0.23 or 0.99, and p = 0.18, respectively). Those prescribed hydralazine or nitrates were more likely to readmit (both p = 0.01). Diabetes and hyperlipidemia were associated with increased readmission (p = 0.01 and 0.05). CONCLUSIONS: This study did not show a significant difference in 30-day readmission rate based on appropriate discharge medications for both COPD and HFrEF. The comorbidities diabetes and hyperlipidemia and prescription of hydralazine or nitrates were significantly associated with increased readmission rate. Larger patient populations may be needed to assess if guideline based discharge medication prescribing is associated with reduced 30-day readmissions for COPD. PMID- 27692136 TI - Effects of omalizumab in severe asthmatics across ages: A real life Italian experience. AB - BACKGROUND: This retrospective study aimed at evaluating long-term effects of Omalizumab in elderly asthmatics in a real-life setting. METHODS: 105 consecutive severe asthmatics (GINA step 4-5; mean FEV1% predicted:66 +/- 15.7) treated with Omalizumab for at least 1 year (treatment mean duration 35.1 +/- 21.7 months) were divided into 3 groups according to their age at Omalizumab treatment onset: 18-39, 40-64 and >= 65 years. RESULTS: Comorbidities, number of overweight/obese subjects and patients with late-onset asthma were more frequent among older people. A similar reduction of inhaled corticosteroids dosage and SABA on-demand therapy was observed in all groups during Omalizumab treatment; a similar FEV1 increased was also observed. Asthma Control Test (ACT) improved significantly (p < 0.001) in the three groups, increasing from 15 [IQR:12-18] to 24 [IQR:22-25] in younger subjects, from 14 [IQR:10-16] to 21 [IQR:20-23] in the 40-64-year-group and from 15 [IQR:12-16] to 20 [IQR:18-22] in elderly patients where improvement was lower (p = 0.039) compared to younger people. Asthma exacerbations decreased significantly after Omalizumab but the percentage of exacerbation-free patients was higher in younger people (76.9%) compared to middle aged patients (49.2%) and the elderly (29%) (p = 0.049). After Omalizumab treatment, the risk for exacerbations was lower in subjects aged 40-64 (OR = 0.284 [CI95% = 0.098-0.826], p = 0.021) and 18-39 (OR = 0.133 [CI95% = 0.026-0.678], p = 0.015), compared to elderly asthmatics. Also, a significantly reduced ACT improvement (beta = -1.070; p = 0.046) passing from each age class was observed. CONCLUSION: Omalizumab improves all asthma outcomes independently of age, although the magnitude of the effects observed in the elderly seems to be lower than in the other age groups. PMID- 27692138 TI - Coexistence of asthma and polycystic ovary syndrome: A concise review. AB - Asthma may be associated with polycystic ovary syndrome (PCOS), and possibly patients with PCOS have a more severe type of asthma. The purpose of this systematic literature review is to summarize evidence of a coexistense of PCOS and asthma using the available literature. The search was completed on 01.01.2016. English language articles were retrieved using the search terms 'Asthma' AND 'PCOS', 'Asthma' AND 'systemic inflammation', 'Asthma' AND 'metabolic syndrome', 'asthma' AND 'gynaecology', 'PCOS' AND 'systemic inflammation', 'PCOS' AND 'metabolic syndrome', 'PCOS' AND 'allergy'. Five papers meeting prespecified search criteria were found of which two were registry studies of relevance. The current literature supports a coexistense of PCOS and asthma and gives us an indication of the causes for the possible link between PCOS and asthma. Further research in the area must be conducted to determine the exact nature and magnitude of the association. PMID- 27692137 TI - Clinical features and natural history of interstitial pneumonia with autoimmune features: A single center experience. AB - OBJECTIVE: To describe the clinical phenotype and natural history of a cohort of patients with interstitial pneumonia with autoimmune features (IPAF). METHODS: A retrospective, single center study of 56 patients with IPAF evaluated between February 2008 and August 2014. All clinical data were extracted from the electronic medical record and longitudinal changes in forced vital capacity (FVC) were analyzed with mixed-effects, piecewise linear regression models that considered time as a continuous factor. RESULTS: All patients fulfilled classification criteria for IPAF. The majority were women (71%) and never smokers (68%). The most frequently identified clinical features were Raynaud's phenomenon (39%), distal digital fissuring (29%), Gottron's sign (18%) and inflammatory arthropathy (16%). The most frequently identified serologies were antinuclear antibody (ANA) (48%), anti-Ro (SSA) (43%) and anti-tRNA-synthetase antibodies (36%). Nonspecific interstitial pneumonia (NSIP) (57.1%) followed by NSIP with organizing pneumonia (18%) were the most common radiologic patterns, while usual interstitial pneumonia was identified in only 9%. All but one patient was treated with immunosuppression: prednisone (82%) and mycophenolate mofetil (76%) were the most frequently used agents. During a follow-up period of 284.9 +/- 141.3 days, modeled longitudinal FVC% was stable (slope = 0.69/year) and no deaths were observed in the cohort. CONCLUSIONS: In this single center study, patients with IPAF were predominately non-smoking women with high-resolution computed tomography scans that suggested NSIP. Their pulmonary physiology was stable, and during limited follow-up, no deaths were observed. Prospective and multi-center studies are needed to better inform our understanding of IPAF. PMID- 27692139 TI - Socioeconomic inequalities in adherence to inhaled maintenance medications and clinical prognosis of COPD. AB - BACKGROUND: Low socioeconomic status has been associated with adverse outcomes in chronic obstructive pulmonary disease (COPD), but population-based data are sparse. We examined the impact of education, employment, income, ethnicity, and cohabitation on the risk of suboptimal adherence to inhaled medication, exacerbations, acute admissions, and mortality among COPD patients. METHODS: Using nationwide healthcare registry data we identified 13,369 incident hospital clinic outpatients with COPD during 2008-2012. We estimated medication adherence as proportion of days covered (PDC) one year from first contact. With Poisson regression we computed adjusted relative risks (aRR) of poor adherence and non use. With Cox regression we calculated adjusted hazard ratios (aHR) of clinical outcomes. RESULTS: 32% were poor adherers (PDC<0.8) and 5% non-users (PDC = 0). Analyses showed a higher risk of poor adherence among unemployed (aRR1.36, 95% CI 1.20-1.54), low income patients (aRR = 1.07, 95% CI 1.00-1.16), immigrants (aRR = 1.29, 95% CI 1.17-1.44), and patients living alone (aRR = 1.17, 95% CI 1.11 1.24). Similarly, non-use was associated with unemployment (aRR = 2.75, 95% CI 2.09-3.62), low income (aRR = 1.37, 95% CI 1.10-1.70), immigrant status (aRR = 1.56, 95% CI 1.17-2.08), and living alone (aRR = 1.53, 95% CI 1.30-1.81). Low education was associated with exacerbations (aHR = 1.21, 95% CI 1.10-1.35) and admissions (aHR = 1.22, 95% CI 1.07-1.38). Low income was associated with admissions (aHR = 1.20, 95% CI 1.09-1.32), and death (aHR = 1.11, 95% CI 0.99 1.25). The unemployed and those living alone had lower exacerbation-risk but higher mortality-risk. CONCLUSIONS: In Denmark, health equity is a stated priority in a public health care system. Nevertheless, there are substantial socioeconomic inequalities in COPD treatment and outcomes. PMID- 27692140 TI - Bronchoalveolar lavage for the diagnosis of Pulmonary Langerhans cell histiocytosis. AB - BACKGROUND: The histologic diagnosis of Pulmonary Langerhans cell histiocytosis (PLCH) is invasive and can cause complications. To confirm the diagnosis of PLCH, guidelines therefore recommend measuring CD1a-positive bronchoalveolar lavage fluid (BALF) cells despite its poor sensitivity and specificity. Thus, an improved diagnostic accuracy of BALF cell analysis would be desirable. METHODS: Using four-colour flow cytometry, plasmacytoid and myeloid dendritic cells (DCs) were analysed in BALF of 10 newly diagnosed, untreated, smoking patients with PLCH, and compared with BALF DCs from 40 asymptomatic smokers and 21 never smokers. RESULTS: Compared with controls, myeloid DCs (median: 0.79% of BALF leukocytes) and their subpopulation of Langerhans cells (median: 0.44% of BALF leukocytes) were not increased in PLCH. Patients with PLCH displayed a normal expression of the maturity marker CD83 on BALF myeloid DCs. However, the expression of the co-signaling molecule CD80 on BALF myeloid DCs was significantly lower than in both control groups, with the lowest expression found in more severe disease (presence of cysts > 2 cm in diameter). Based on receiver operating characteristic (ROC) curve analysis, a cut-off of 53% CD80-positive BALF myeloid DCs was optimal for the diagnosis of PLCH, yielding a sensitivity of 0.90 and a specificity of 0.90. CONCLUSIONS: BALF Langerhans cells are not increased in PLCH. However, PLCH is characterised by a low expression of CD80 on BALF myeloid DCs. Due to its considerably higher sensitivity and specificity, this marker appears to be more appropriate to diagnose PLCH than the currently recommended marker CD1a. PMID- 27692141 TI - Hepatoid adenocarcinoma of the lung: Review of a rare form of lung cancer. AB - RATIONALE: Hepatoid adenocarcinoma (HAC) is a rare malignant lung tumor that histologically resembles typical hepatocellular carcinoma (HCC) when it is metastatic to the lung. To date, this clinical entity has not been highlighted in the pulmonary literature. OBJECTIVE: We present a review of all known cases of HAC, including the relevant clinical and histopathological features important for pulmonologists. MEASUREMENTS AND MAIN RESULTS: The purpose of this report is to present a new case of HAC, with typical clinical and histologic features of this malignancy, and to summarize findings of previously reported cases. A systematic literature search of the electronic database PUBMED was conducted to identify all cases of hepatoid adenocarcinoma reported in the English literature, between January 1980 and June 2015. HAC and HCC can be distinguished by immunohistochemical staining. HAC usually presents as a large bulky solitary mass in the upper lobe; there is an exceedingly high prevalence in males and most patients with this tumor are smokers. Serum alpha-fetoprotein (AFP) in very high levels has been a distinguishing feature of this tumor. Nodal and distant metastases are common at initial presentation and, as a result, the prognosis is very poor. Resection and long-term survival, however, have been reported. CONCLUSION: Hepatoid adenocarcinoma, first described as a gastric tumor, has also been described in the lung. It morphologically resembles and must be distinguished from metastatic HCC of the lung. While most tumors produce AFP, the case we present demonstrates that this should not be a criterion for diagnosis. PMID- 27692142 TI - Tuberculosis. Digging deep in the soul of humanity. AB - Tuberculosis (TB) is one of the oldest infectious diseases that affected humankind. A quintessential social disease, TB remains one of the world's deadliest communicable diseases, with still a high mortality and burden of disease. Social representations of TB focus on aspects associated to feelings and manifestations awakened by the disease, sometimes reinforcing stigmas and prejudices about the way of perceiving TB. TB is a historic disease now reborn with a deeper social stigma. Despite the modest reduction in TB incidence worldwide, its incidence is still rising in certain crisis-affected populations like refugees, and in those bearing high prevalence of HIV, persisting poverty, especially in the developing world. Fear and stigma may appear justified with the increasing rates of multi-drug resistant (MDR) TB, and now extremely drug resistant (XDR) TB. However, stigmatization of TB poses serious obstacles to current TB control efforts, as socio-cultural aspects can influence adherence to TB treatment. PMID- 27692143 TI - Molecular mechanisms underlying hyperoxia acute lung injury. AB - The management of acute hypoxemic respiratory failure frequently includes the use of supraphysiological fractions of inspired oxygen (FiO2), which can be beneficial in the short-term but not without risks in the long-term, causing acute lung injury (ALI). Over the last few years, much attention has been devoted to the intracellular signaling transduction pathways that lead to hyperoxia induced cell damage, particularly MAP kinase cascades. Identification of involved signaling molecules and understanding of the regulation of the main signal transduction pathways might provide the basis for improving the outcome of patients under high FiO2 exposure through more effective therapeutic interventions. This review, which includes studies published from 1987 to 2015, presents an overview on recent progresses in the hyperoxia ALI field with special emphasis on potential therapeutic targets and clinical approaches based on the molecular mechanisms underlying hyperoxia-induced inflammation. Further studies are needed to gain deeper insight into controversial molecular mechanisms underlying hyperoxia-induced cell death, which may play a critical role in future pharmacological interventions, as well as into hyperoxia-induced cell damage, that could monitor and therefore prevent hyperoxia ALI. PMID- 27692145 TI - The relationship of body habitus and respiratory function in Duchenne muscular dystrophy. AB - BACKGROUND: The multidisciplinary care of Duchenne muscular dystrophy (DMD) incorporates management of nutrition and the respiratory system, however the effect of body habitus on respiratory function in DMD is poorly understood. The present study examined the impact of nutritional status on respiratory function in DMD to guide further treatment strategies. METHODS: Anthropometric and respiratory parameters, such as body mass index (BMI) z-scores, forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were retrospectively analysed with a mixed linear model in 34 DMD patients. Cross sectional analysis of cough peak flow (CPF) in upright and supine positions and body fat mass were examined in 12 DMD patients. RESULTS: Respiratory function in DMD patients was significantly related to BMI Z-score (P < 0.001), age (P < 0.05) and mobility (P < 0.001). DMD patients with greater BMI Z-score had increased respiratory function, even when adjusting for age and mobility status, with a 1 unit increase in BMI z-score associated with a 7.43% increase in FVC% predicted (P < 0.001). Body fat mass was adversely associated with FVC with a 1% body fat increase associated with a 1.5% reduction in FVC (P < 0.05). CPF values were significantly lower in supine compared to upright position (P = 0.005) and greater postural reductions in CPF were associated with higher body fat percent, with a 1% body fat increase associated with a 1.5% increase in postural CPF difference (P < 0.05). CONCLUSION: The present study reinforces the importance of weight management in DMD, showing that a higher weight profile and lower adiposity have better respiratory outcomes. Furthermore, attention to body position with airway clearance techniques will maximize their effectiveness. PMID- 27692144 TI - Bronchodilator response in wheezing infants assessed by the raised volume rapid thoracic compression technique. AB - BACKGROUND: Bronchodilator response (BDR) analyzed by the raised volume rapid thoracic compression (RVRTC) in wheezing infants is not yet well described, although bronchodilators (BD) are routine in the treatment of this population. OBJECTIVE: To evaluate BDR by RVRTC technique in infants with recurrent wheezing and compare to control group. METHOD: Cross sectional study, 45 infants, age 56 weeks (38-67 weeks). Two groups: wheezing group (WG: history of recurrent wheezing) and control group (CG). RVRTC was evaluated, FVC, FEV0.5, FEF50, FEF75, FEF85, FEF25-75 were measured. Salbutamol was delivered to infants and RVRTC evaluated again. BDR was determined by the increase greater than two standard deviation from the mean change in the CG. RESULTS: In WG (n = 32) lung function was worse than in CG (n = 13): FEV0.5: 0.0(-0.9-0.9z score) vs 0.8(0.2-1.4z score); FEF50: 0.2(-0.3-1.1z score) vs 0.9(0.5-1.4z score); and FEF25-75: 0.2( 0.5-1.1z score) vs 1.1(0.6-1.6z score), respectively, p < 0.05. Both groups had similar increase after BD. In WG 11 patients (34%) were responder and these had worse lung function compared to nonresponder (n = 21) (p < 0.05). The increase in lung function after BD in responder was higher than in nonresponder: FEV0.5: 6.5(2.1-7.1%) vs -0.5(-2.5-0.7%), FEF50: 5.1(2.7-11.7%) vs 0.4(-1.1-2.8%), FEF75: 20.7(4.7-23.6%) vs -1.3(-6.4-3.9%), FEF25-75: 9.9(3.8-16.4%) vs 0.0(-1.5-1.0%), respectively, p < 0.05. CONCLUSION: 34% WG showed BDR measured by the RVRTC. The best variables to detect BDR were FEF75, FEF25-75 and FEV0.5. Patients with worse lung function showed better response to BD. PMID- 27692147 TI - Real life data on incidence and risk factors of severe asthma exacerbations in children in primary care. AB - Real-life data on the incidence rates (IR) and risk factors of severe asthma exacerbations in children are sparse. We aimed to assess IR and risk factors of severe asthma exacerbations in children in real life. We conducted a population based cohort study using a Dutch GP database containing complete medical records of >1 million patients. All records of children with physician-diagnosed asthma aged 5-18 years between 2000 and 2012 were examined for exacerbations, defined as either hospitalization, emergency department visit or need of systemic steroids for asthma. IR was expressed as number of exacerbations per person year (PY). We identified 14,303 asthmatic children with 35,118 PY of follow-up and 732 exacerbations. The overall IR was 2.1/100PY (95% CI 1.9-2.2), 4.1/100PY (3.8-4.4) for children on asthma treatment. Re-exacerbation occurred in 2% (1.3-4.3) of patients within 1 month, in 25% (20.6-28.8) within 1 year. Predictors for (frequent) exacerbations were age, medication use and prior exacerbations (all p < 0.001). The overall IR of severe asthma exacerbations was 4/100PY in children on asthma treatment, highest in spring and fall. 25% of the patients with an exacerbation will experience a next exacerbation within 1 year. More severe asthma is a predictor of subsequent and future exacerbations. PMID- 27692146 TI - Primary ciliary dyskinesia in Israel: Prevalence, clinical features, current diagnosis and management practices. AB - BACKGROUND: Primary Ciliary Dyskinesia (PCD) is rare and its features in Israel have not been described. AIMS: to assess prevalence utilizing state-of-the-art diagnostic techniques, and describe clinical features, diagnostic and management practices in Israel. METHODS: A national multicenter study from 2012 to 2013 recruited patients diagnosed or suspected of having PCD. Diagnosis was verified using: nasal Nitric Oxide (nNO); High-speed Video Microscope Analysis (HVMA); Transmission Electron Microscopy (TEM) of cilia; Immuno-fluorescence staining (IF) for ciliary proteins, and genetic analysis. RESULTS: Of the 203 patients recruited from 14 pediatric centers, 150 had a PCD diagnosis verified. Median age was 15.05y, with range 0.15-60.5y. PCD prevalence was 1:54,000 for the general population and 1:25,000 in children (5-14 y). For the non-Jewish (mainly Druze and Arab Moslem) compared to Jewish populations, prevalence was 1:16,500 and 1:139,000 respectively (p < 0.0001) and parental consanguinity was 85.4% and 21.9% respectively (p < 0.0001). Clinical features included bronchiectasis (88%), rhinitis (81%), recurrent pneumonia (78%), recurrent otitis (62%), neonatal pneumonia (60%) and situs inversus (42%). Prior diagnostic practices varied widely between centers with TEM assessed in 55% and abnormal in 61% of these. Management included antibiotics and airway clearance. Diagnostic verification revealed for 150 PCD patients: 81% nNO<233 ppb, 62% abnormal HVMA, 51% diagnostic TEM, 58% diagnostic IF and, 57% genetic diagnosis. CONCLUSIONS: PCD in Israel is rare, with comprehensive diagnostic tests showing prevalence in children similar to Europe. Prevalence was higher in non-Jews, associated with parental consanguinity. Diagnostic and management practices vary. Referral centers providing comprehensive diagnostic and care capabilities should be established. PMID- 27692148 TI - A pilot study to monitor changes in spirometry and lung volume, following an exacerbation of Chronic Obstructive Pulmonary Disease (COPD), as part of a supported discharge program. AB - BACKGROUND: One-third of patients with an exacerbation of Chronic Obstructive Pulmonary Disease(COPD) are re-hospitalised at 90 days. Exacerbation recovery is associated with reductions in lung hyperinflation and improvements in symptoms and physical activity. We assessed the feasibility of monitoring these clinical parameters in the home. We hypothesised that the degree of change in spirometry and lung volumes differs between those who had an uneventful recovery and those who experienced a further exacerbation. METHODS: Hospitalised patients with an acute exacerbation of COPD referred for a supported discharge program participated in the study. Spirometry and Inspiratory Vital Capacity(IVC) were measured in the home at Days 1, 14 and 42 post-discharge. Patients also completed Medical Research Council(MRC), Borg and COPD Assessment Test(CAT) scores and were provided with a tri-axial accelerometer. Any new exacerbation events were recorded. RESULTS: Sixty-five patients with 72 exacerbation episodes were recruited. Fifty percent experienced a second exacerbation. Adequate IVC measurements were achieved by 90%, while only 70% completed spirometry. Uneventful recovery was accompanied by significant improvements in physiological measurements at day14, improved symptom scores and step count, p < 0.05. Failure of MRC to improve was predictive of re-exacerbation(Area Under Receiver Operating Curve(AUROC) 0.6713) with improvements in FEV1>=100 ml(AUROC 0.6613) and mean daily step count >=396 steps(AUROC 0.6381) predictive of recovery. CONCLUSION: Monitoring the pattern of improvement in spirometry, lung volumes, symptoms and step count following a COPD exacerbation may help to identify patients at risk of re-exacerbation. It is feasible to carry out these assessments in the home as part of a supported discharge programme. PMID- 27692149 TI - Physiological responses during exercise with video games in patients with cystic fibrosis: A systematic review. AB - BACKGROUND: Interactive video games are recently being used as an exercise tool in cystic fibrosis (CF). This study aimed to assess the literature describing whether video games generate a physiological response similar to the exercise intensity needed for training in CF. METHODS: An online search in PubMed, Embase, Cochrane, SciELO, LILACS and PEDro databases was conducted and original studies describing physiological responses of the use of video games as exercise in CF were included. RESULTS: In four, out of five studies, the heart rate achieved during video games was within the standards recommended for training (60-80%). Two studies assessed VO2 and showed higher levels compared to the six-minute walk test. No desaturation was reported. Most games were classified as moderate intensity. Only one study used a maximum exercise test as comparator. CONCLUSION: Interactive video games generate a heart rate response similar to the intensity required for training in CF patients. PMID- 27692150 TI - Respiratory drugs and macrolides prevent asthma exacerbations: A real-world investigation. AB - OBJECTIVE: We investigated the real-world effectiveness of several drugs (including short- and long-acting beta-agonists [SABAs and LABAs], inhaled corticosteroids [ICS], and antibiotics) in preventing severe asthma exacerbations by carrying-out a large observational study based on the healthcare utilization databases of the Italian Lombardy Region. METHODS: We identified all patients aged 6-40 years who performed an Emergency Department visit for asthma during 2010-2012 as cases. To address bias due to unmeasured confounders, we implemented a case-crossover (CC) design. Addressing other specific sources of systematic errors (e.g. protopathic bias) was of particular concern in this study. RESULTS: A total of 7300 cases were included in the study. The CC odds ratios (95% confidence intervals) for current vs. past use were 0.81 (0.71, 0.92) for SABAs, 0.83 (0.72, 0.96) for ICS, 0.78 (0.66, 0.91) for LABA/ICS fixed combinations, 0.79 (0.65, 0.97) for other respiratory drugs, and 0.79 (0.69, 0.92) for macrolides antibiotics. Sensitivity analyses showed that our results were robust with respect to several sources of bias. CONCLUSIONS: Our study provides evidence from the real-world clinical practice on the effectiveness of several respiratory drugs and macrolides in reducing the risk of severe asthma exacerbations. PMID- 27692151 TI - Computed tomography (CT)-assessed bronchodilation induced by inhaled indacaterol and glycopyrronium/indacaterol in COPD. AB - BACKGROUND: Our previous studies suggested that the site of bronchodilation on CT might differ between inhaled beta2 agonists and inhaled anticholinergics in COPD. AIM: To assess and compare the bronchodilation effects of inhaled indacaterol and glycopyrronium/indacaterol by airway generation in large airways using CT. METHODS: CT scans at full inspiration and pulmonary function tests were done in 25 patients with moderate-severe COPD before and 4-5 weeks after daily inhalation of indacaterol and again another 4-5 weeks after inhalation of glycopyrronium/indacaterol. Airway inner luminal area (Ai) at the 3rd (segmental) to 6th generation of 8 selected bronchi, a total of 32 sites, in the right lung was analyzed on 3 occasions. Our proprietary software enables us to select the same airways and the same measurement sites for comparison, with simultaneous confirmation using two screens on the computer. RESULTS: The overall increase of Ai (DeltaAi, %) averaged at all 32 measurement sites induced by glycopyrronium/indacaterol had a significant correlation with FEV1 improvement (r = 0.7466, p < 0.0001). Both DeltaAi, % with indacaterol and DeltaAi, % with additional glycopyrronium were significant at the 3rd to 6th generations. Remarkable increases in DeltaAi, % were found at the 5th and 6th generations in several subjects with indacaterol or additional glycopyrronium. There were no significant site-differences in the bronchodilation pattern caused by indacaterol and by glycopyrronium/indacaterol at any of the 3rd to 6th generations. CONCLUSIONS: Additional bronchodilation with glycopyrronium was demonstrated by CT at the 3rd to 6th generations, with no site-specific differences in bronchodilation between indacaterol and glycopyrronium/indacaterol. This study was registered in the UMIN Clinical Trials Registry (UMIN-CTR) system (http://www.umin.ac.jp/. ID. UMIN000012043). PMID- 27692152 TI - Respiratory pattern in a FSHD pediatric population. AB - Facioscapulohumeral muscular dystrophy (FSHD) is an autosomal dominant inherited disorder characterized by selective weakness of face and upper arms and girdle. Respiratory involvement in FSHD has been described mainly in the most severely affected patients. In this work we tested the respiratory function by spirometry in 12 patients affected by FSHD with onset before 18 years. Spirometry results were correlated with motor involvement and compared to aged matched group of Becker patients. Of note FSHD patients present a peculiar pattern characterized by a flat shape in flow-volume loop. Respiratory volumes correlate with clinical severity and expiratory phase is specifically affected in comparison to other muscular dystrophies. PMID- 27692153 TI - Diastolic pulmonary gradient predicts outcomes in group 1 pulmonary hypertension (analysis of the NIH primary pulmonary hypertension registry). AB - BACKGROUND: Diastolic pulmonary gradient (DPG), calculated as the difference between pulmonary artery diastolic pressure and mean pulmonary capillary wedge pressure >= 7 mmHg is associated with pulmonary vascular disease and portends poor prognosis in heart failure (HF). The prognostic relevance of DPG in group 1 pulmonary hypertension (PH) is uncertain. METHODS: Using the Pulmonary Hypertension Connection (PHC) risk equation for 225 patients in the NIH-PPH, the 5-year probability of death was calculated, which was then compared with DPG using a Cox proportional hazards model. Kaplan-Meier survival curves were determined for two cohorts using the median DPG of 30 mmHg as cutoff, and significance was tested using the log-rank test. RESULTS: The mean age was 38.1 +/- 16.0 years old, 63% female, and 72% were "white". The mean DPG was 31.6 mmHg +/- 13.8 mm Hg and only 1.8% had a DPG <7 mm Hg. Increasing DPG was significantly associated with increased 5-year mortality even after adjustment for the PHC risk equation (HR 1.29 per 10 mm Hg increase). When DPG was dichotomized based on the median of 30 mm Hg, the HR for DPG >30 mm Hg with respect to 5-year mortality was 2.03. After adjustment for pulmonary artery systolic pressure (PASP), increasing DPG remained significantly associated with decreased 5 years survival (HR 1.99 for DPG > 30 mm Hg). CONCLUSIONS: DPG is independently associated with survival in group 1 PH patients even after adjustment for the PHC risk equation or PASP. Patients with increased DPG had a 2-fold increased risk of mortality. The use of DPG for guiding treatment and prognosis in group 1 PH should be further investigated. PMID- 27692154 TI - Determinants of exercise-induced oxygen desaturation including pulmonary emphysema in COPD: Results from the ECLIPSE study. AB - Exercise-induced oxygen desaturation (EID) is related to mortality in patients with chronic obstructive pulmonary disease (COPD). We investigated: (1) the prevalence of EID; (2) the relative-weight of several physiological determinants of EID including pulmonary emphysema, and (3) the relationship of EID with certain patients' clinical characteristics. Data from 2050 COPD patients (age: 63.3 +/- 7.1years; FEV1: 48.7 +/- 15.7%pred.) were analyzed. The occurrence of EID (SpO2post <=88%) at the six-minute walking test (6MWT) was investigated in association with emphysema quantified by computed-tomography (QCT), and several clinical characteristics. 435 patients (21%) exhibited EID. Subjects with EID had more QCT-emphysema, lower exercise capacity and worse health-status (BODE, ADO indexes) compared to non-EID. Determinant of EID were obesity (BMI>=30 kg/m2), impaired FEV1 (<=44%pred.), moderate or worse emphysema, and low SpO2 at rest (<=93%). Linear regression indicated that each 1-point increase on the ADO-score independently elevates odds ratio (<=1.5fold) for EID. About one in five COPD patients in the ECLIPSE cohort present EID. Advanced emphysema is associated with EID. In addition, obesity, severe airflow limitation, and low resting oxygen saturation increase the risk for EID. Patients with EID in GOLD stage II have higher odds to have moderate or worse emphysema compared those with EID in GOLD stage III-IV. Emphysematous patients with high ADO-score should be monitored for EID. PMID- 27692155 TI - Clinical characteristics in patients with asymmetric idiopathic pulmonary fibrosis. AB - BACKGROUND: A group of patients with idiopathic pulmonary fibrosis (IPF) presents with disease affecting one lung markedly more than the other. At this time, it is unclear how this population differs from those who present with more symmetric disease. We sought to explain the characteristics of the asymmetric group and how their disease progresses. METHODS: In this retrospective case-control study we accessed an interstitial lung disease (ILD) database and identified 14 asymmetric IPF cases via high-resolution computed tomography (HRCT) scoring of each lung lobe's disease severity. We identified 28 symmetric IPF controls from the same database using the same methods, and compared the clinical features of each group. RESULTS: Patients with asymmetric disease exhibited similar demographics as those in the general IPF population; they were predominantly male (64%), elderly (69 years old), and used tobacco (57%). We found a trend toward significantly increased all-cause mortality in the case population two years following diagnosis (p = 0.089). Pulmonary function tests were significantly lower in the case group at the time of diagnosis, then both groups experienced gradual decline. We found no statistically significant differences in number of IPF exacerbations (cases 43%, controls 39%, p = 0.824) and gastro-esophageal reflux (both groups 50%). CONCLUSION: Patients with asymmetric IPF resemble patients in the general IPF population but may have a lower overall survival rate. Further systemic factors may be studied to identify reasons for disease asymmetry and clinical decline in this population. PMID- 27692156 TI - Hypothesis: Irisin is a metabolic trigger for the activation of the neurohormonal axis governing puberty onset. AB - A large body of data suggests that body weight influences puberty onset and adult reproduction. However, the underlying mechanism of how body weight influences puberty onset and fertility is not completely understood. The hypothalamic neuronal circuit regulating reproduction is restrained by inhibitory signals during childhood. At the time of puberty, these inhibitory signals are weakened and supplanted by stimulatory signals that, in turn, stimulate the release of gonadotropin-releasing hormone (GnRH) - a hypothalamic neuropeptide governing reproduction. A number of studies, however, suggest that puberty commencement occurs when body (fat) weight reaches a certain threshold, which is critical for the initiation of puberty and for support of the adult reproductive function. Previously, various signals have been studied which might link body (fat) weight related information to the hypothalamic neuronal network regulating reproduction. However, the nature of the signal(s) that may link body fat and/or muscle mass with the hypothalamic neuronal network governing reproduction is still unclear. It has been intuitively speculated that augmentation of such signal(s) will cause a restriction of inhibitory input and activation of stimulatory input to GnRH secreting neurons at the time of puberty onset. Therefore, the unveiling of such signal(s) will greatly help in understanding the mechanism of puberty onset. Recently, it has been shown that expression of fibronectin type III domain containing-5 (FNDC5) mRNA in central and peripheral tissues upsurges during postnatal development, especially around the time of puberty onset. Moreover, the systemic level of irisin - one of the protein products of the FNDC5 gene that is secreted as myokine and adipokine - also rises during postnatal development and correlates with the timing of puberty onset. Therefore, we propose here that irisin might serve as a possible signal for linking body fat/muscle mass with the hypothalamic center governing reproductive function. We hypothesize that irisin acts as a trigger for the activation of the hypothalamic neuronal network monitoring the onset of puberty. PMID- 27692157 TI - Connecting the obesity and the narcissism epidemics. AB - Obesity and metabolic syndromes are major threats to health in both developed and developing countries. This opinion article is a holistic attempt to understand the obesity epidemic, by connecting it to the widespread narcissism in society. The narcissism epidemic refers to an increased prevalence of status-striving individualism and a decreased sense of community, observed in Westerns populations and spreading worldwide. Based on social personality and evolutionary psychology approaches, I speculate that this rise of narcissism underlies a steep social hierarchy resulting in increase of social stress. This social stress markedly affects individuals who are sensitive to social hierarchy dominance due to their personality, yet are relegated at a lower social position. I speculate that over-eating is one major mechanism for coping with this stress, and discuss the possibility that visceral fat may constitute an adaptive behaviour to the lower social hierarchy position, which is perceived as unjust. Connecting the prevalence of obesity to the narcissism epidemic allows for a more thorough examination of factors, which contribute to obesity, which includes early difficult childhood experience, lower rank, and the overall competitive framework of the society. PMID- 27692159 TI - Could tea polyphenols be beneficial for preventing the precocious puberty? AB - Precocious puberty which impacts children physically and psychologically has become one of the health problem over the world. However, the mechanism and preventive measures of precocious puberty is still not clear. Recent studies suggested that leptin may act as the 'permissive factor' to initiate the puberty by regulating gonadotrophin-releasing hormone secretion. Previous evidence from animal and human studies found that tea polyphenols can reduce serum leptin levels in vivo and inhibit the expression of leptin in adipose tissue. This article focus on whether tea polyphenols could delay the onset of puberty by reducing leptin levels. To verify the possibility of tea polyphenols on preventing precocious puberty, animal experiment can be used. Our hypothesis that tea polyphenols could prevent the precocious puberty may provide important potential way for the prevention and control of children precocious puberty. PMID- 27692158 TI - Soluble adhesion molecules in patients with acute coronary syndrome after percutaneous coronary intervention with drug-coated balloon, drug-eluting stent or bare metal stent. AB - Adhesion molecules play an important role in inflammation, atherosclerosis and coronary artery disease (CAD). These molecules are expressed on the surface of dysfunctional endothelial cells, causing inflammatory cells from the circulation to adhere and migrate through the endothelium. Their expression is upregulated in acute coronary syndrome (ACS) and after percutaneous coronary intervention (PCI). The contact between stent struts and endothelium upregulates endothelial cell gene expression, endothelial cell activation and inflammation. The paclitaxel or sirolimus eluting stents inhibited expression of adhesion molecules in several studies and reduced the incidence of major adverse cardiac events (MACE) after drug-eluting stent (DES) over bare metal stent (BMS) implantation. Therefore, we propose that elevated serum levels of the soluble adhesion molecules after primary PCI in patients treated with BMS or DES implantation versus drug-coated balloon (DCB) application to the vulnerable coronary plaque might be a predictor of MACE and further adverse outcomes. Consequently, DCB-only strategy in patients with ACS might be a superior approach in comparison to BMS implantation and non inferior approach when compared to DES implantation. PMID- 27692160 TI - DCoH: A novel biomarker for diagnosing acute kidney injury. AB - Initial diagnosis of acute kidney injury (AKI) is usually based on measuring serum-creatinine and blood urea nitrogen levels; however such measurements are still poor in identifying renal injuries at initial stages. These standard matrices are not enough to monitor the outcome and progression of AKI. The prognosis prevents proper treatment and timely delay in providing putative therapeutic agents. The cost effective therapies to get delayed, patient health gets compromised and ultimately requires renal transplant due to end-stage renal disease, which is another major problematic factor due to shortage kidney donors. To establish effective therapies for AKI the need will be facilitated by developing and identifying reliable, sensitive biomarkers which can be detected early during all stages of AKI, even during preclinical and clinical studies. Although reaching to human clinical trials takes years of thorough evaluations, preliminary studies should be carried out effectively by: (a) Employing cell culture analysis, (b) use of AKI animal models, studying various gene regulated networks, and biomarkers, and (c) patient serum sampling and testing. As elevated phenylalanine are indicative of AKI onset within 4h, its levels is controlled, 4a Hydroxy-tetrahydrobiopterin dehydratase/dimerization cofactor of HNF-1 (DCoH). There is a possibility of targeting DCoH to the current bedside list of biomarkers involved in AKI onset. PMID- 27692161 TI - A novel treatment for "morning sickness": Nausea of pregnancy could be induced by excess sulfite which molybdenum can help alleviate. AB - Nausea and vomiting of pregnancy (NVP) remains difficult to treat. Last century, thalidomide was used to alleviate NVP, but it caused teratogenesis by interfering with angiogenesis. The gasotransmitters hydrogen sulfide (H2S) and nitric oxide are mutually dependent on each other for their angiogenesis-related functions. Pregnancy-related requirements for increased endogenous H2S could create a temporary excess of sulfite, an H2S catabolite, which is toxic and can induce nausea. Sulfite oxidase, a molybdenum-containing enzyme, catalyzes oxidation of sulfite to sulfate, which can then be excreted or reused by the body. Supplementation with molybdenum should facilitate enhanced sulfite oxidase activity, thus lowering gestationally-elevated sulfite levels in the gastrointestinal tract and easing NVP.

PMID- 27692163 TI - Myeloid derived suppressor cell: A new player in periodontal disease? AB - Periodontal disease can be initiated by a shift from a symbiotic to a dysbiotic microbial community. An increase in the recruitment of leukocytes and production of inflammatory cytokines, chemokines and oxidative stress are generated by this shift. In periodontitis, an exacerbated, poorly specific and effective inflammatory response is mounted. Moreover, failure in the inflammation resolving mechanism leads to establishment of a chronic inflammatory process, resulting in the progressive destruction of bone and soft tissue. In different diseases presenting chronic inflammation some important players of immune response are defectives. Thus, an immunosuppressive environment could be induced during chronic inflammation. Myeloid derived suppressor cells (MDSC), a heterogenic group of immature myeloid cells with potent immune suppressive activity, are increased in several acute and chronic inflammatory diseases. Dysbiosis-mediated inflammation can induce increased frequency of MDSC. In addition, mediators generated in diverse inflammatory diseases have demonstrated to promote expansion, activation and recruitment of MDSC, similar mediators have been described in periodontal disease. MDSC promote generation of nitric oxide (NO) and reactive oxygen species (ROS). Furthermore, MDSC can differentiate in functional osteoclasts. We hypothesize that MDSC are generated during periodontal disease. Review of literature evaluating this hypothesis and possible implications are assed in this work. It encourages the study of MDSC in this common disease. PMID- 27692165 TI - In type 1 diabetics, high-dose biotin may compensate for low hepatic insulin exposure, promoting a more normal expression of glycolytic and gluconeogenic enyzymes and thereby aiding glycemic control. AB - In type 1 diabetics, hepatic exposure to insulin is chronically subnormal even in the context of insulin therapy; as a result, expression of glycolytic enzymes is decreased, and that of gluconeogenic enzymes is enhanced, resulting in a physiologically inappropriate elevation of hepatic glucose output. Subnormal expression of glucokinase (GK) is of particular importance in this regard. Possible strategies for correcting this perturbation of hepatic enzyme expression include administration of small molecule allosteric activators of GK, as well as a procedure known as chronic intermittent intravenous insulin therapy (CIIIT); however, side effects accompany the use of GK activators, and CIIIT is time and labor intensive. Alternatively, administration of high-dose biotin has potential for modulating hepatic enzyme expression in a favorable way. Studies in rodents and in cultured hepatocytes demonstrate that, in the context of low insulin exposure, supra-physiological levels of biotin induce increased expression of GK while suppressing that of the key gluconeogenic enzyme phosphoenolpyruvate carboxykinase. These effects may be a downstream consequence of the fact that biotin down-regulates mRNA expression of FOXO1; insulin's antagonism of the activity of this transcription factor is largely responsible for its modulatory impact on hepatic glycolysis and gluconeogenesis. Hence, high-dose biotin may compensate for subnormal insulin exposure by suppressing FOXO1 levels. High-dose biotin also has the potential to oppose hepatic steatosis by down-regulating SREBP-1 expression. Two pilot trials of high-dose biotin (16 or 2mg per day) in type 1 diabetics have yielded promising results. There is also some reason to suspect that high-dose biotin could aid control of diabetic neuropathy and nephropathy via its stimulatory effect on cGMP production. Owing to the safety, good tolerance, moderate expense, and current availability of high-dose biotin, this strategy merits more extensive evaluation in type 1 diabetes. PMID- 27692164 TI - Hair follicle characteristics as early marker of Type 2 Diabetes. AB - Type 2 Diabetes mellitus (DM2) includes a continuum of metabolic disorders characterized by hyperglycemia that causes several chronic long-term complications such as coronary artery disease, peripheral arterial disease, nephropathy, and neuropathy. The hair follicle could reveal signs of early vascular impairment, yet its relationship to early metabolic injuries has been largely ignored. We propose that in earlier stages of the continuum of DM2 related metabolic disorders, a group of susceptible patients who do not yet meet the diagnostic criteria to be considered as persons with DM2 may present chronic vascular impairment and end organ damage, including hair follicle damage, which can be evaluated to identify an early risk marker. This hypothesis is based in the association found between insulin resistance and alopecia in non-diabetic persons, and the hair loss on the lower limbs as a manifestation of long-term peripheral arterial disease among subjects with DM2. In order to test this hypothesis, studies are required to evaluate if hair follicle characteristics are related to and can predict hyperglycemic complications, and if they do so, which feature of the hair follicle, such as hair growth, best characterizes such DM2 related conditions. If this hypothesis were proven to be true, significant advances towards a personalized approach for early prevention strategies and management of DM2 would be made. By focusing on the hair follicles, early stages of metabolic-related organ damage could be identified using non-invasive low-cost techniques. In so doing, this approach could provide early identification of DM2 susceptible individuals and lead to the early initiation of adequate primary prevention strategies to reduce or avoid the onset of large internal organ damage. PMID- 27692166 TI - The transition from a rural to an urban environment in Africa alters G protein coupled receptor signaling. AB - Urbanization in Africa is associated with an increased incidence of non communicable diseases, yet the cause and the mechanism remain poorly understood. Here, we propose a role for G protein-coupled receptor (GPCR) signaling in the biological changes that occur with urbanization and suggest a critical area of convergence in GPCR signaling might provide a molecular signature for exposure to environmental factors. As a first step in investing this hypothesis, we examined the expression of the G protein alpha, beta and gamma subunit, G protein related kinase, and beta-arrestin genes in a rural and urban population living in Morocco (NCBI GSE8847). Three genes associated with the phosphatidylinositol signaling pathway (GNAQ, GNA11 and GNA15), and one gene controlling the cyclic adenosine monophosphate pathway (GNAI2) was altered by urbanization. Of note, the expression of ARRB1 gene, which encodes the beta-arrestin 1 protein and dampens the cellular responses to extracellular signals, was greater in the rural compared to the urban population (P<0.00002). These preliminary findings support our hypothesis that urbanization fundamentally alters GPCR signaling, resulting in both a qualitative and quantitative change in the signaling process. Because GPCR signaling is involved in a broad spectrum of cellular functions, further research is needed confirm these preliminary findings and to investigate what role GPCRs might have in the biological changes that occur with urbanization. PMID- 27692167 TI - Peptide-based GLP-1/glucagon co-agonists: A double-edged sword to combat diabesity. AB - Diabesity is a new term for obesity-dependent diabetes, which is also associated with cardiovascular and other comorbidities with rising epidemic. Traditional treatments (sulfonylureas and thiazolidinediones) of diabetes are associated with weight gain, except metformin. Newer agents such as glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and Sodium glucose co-transporter 2 inhibitors (SGLT2i) are causing a modest weight reduction, whereas dipeptidyl peptidase-4 inhibitors (DPP-4i) are weight neutral. Oxyntomodulin, a native GLP-1/glucagon receptor agonist produced a superior weight loss and antihyperglycemic effects in obese mice and humans. Recent findings with synthetic dual GLP-1/glucagon receptor agonists have shown a good weight loss and antihyperglycemic profile in diet-induced obese (DIO) mice. Targeting combinations of GLP-1 receptor and glucagon receptor simultaneously with a single peptide may be the better strategy to achieve marked weight loss and considerable glycemic control in diabesity. Cardiovascular safety is very important with new antidiabetic agents due to rosiglitazone controversy. Current on-going clinical trials will clarify the cardiovascular effects of incretin-based therapies in near future. Based on current knowledge and rapid progress in the field, there is a strong possibility that the GLP-1/glucagon receptor co-agonists will likely be the new therapeutic treatment for diabesity for decades to come. PMID- 27692169 TI - Proposal for using time estimation training for the treatment of Parkinson's disease. AB - Studies have shown an association between time perception and the basal ganglia and cortical areas, suggesting a role for these regions in the perception of seconds, minutes, and hours. We present the hypothesis that time estimation training tasks may change the modulatory activity of dopamine in the basal ganglia and the cortical areas related to temporal perception. Through this mechanism, the estimated training time interval can promote a compensatory effect on motor and cognitive performance via a dynamic neural adaptation process. We believe that the training will develop a competition between neural pathways involved in the process of time perception, positively affecting the brain pathways related to Parkinson's disease, and thereby minimizing the cognitive and motor deficits caused by the disease. PMID- 27692170 TI - Vitamin D regulates the production of vascular endothelial growth factor: A triggering cause in the pathogenesis of rheumatic heart disease? AB - Rheumatic heart disease (RHD) remains a major cause of cardiac related mortality and morbidity in the developing countries due to poor diagnosis and lack of proper therapeutics. The definite reason of heart valve injury during RHD is poorly understood. Valvular endothelial cells play an important role in pathogenesis of different cardiovascular diseases. Besides, the regulation of vitamin D (calciferol) and VEGF (vascular endothelial growth factor) results in the functional changes in endothelial cells. However, the crosstalk between vitamin D and VEGF in the pathogenesis of RHD is not yet unfurled. Evidences in the concerned fields are documented by searching through Google Scholar and Pubmed. Literature based survey has revealed that vascular endothelium, especially endothelial cells play important roles in valvular remodelling during cardiovascular diseases. Endothelial cell dysfunction leads to heart valve remodelling, which furthermore initiates the pathogenesis of valvular heart disease. Vitamin D has the potential to maintain the concentration of VEGF in the circulation and induce the function of endothelial cells. Hence, we hypothesize that vitamin D and VEGF homeostasis can alter the function of endothelial cells, which may subsequently trigger the valvular remodelling or even damage of heart valves during the progression of RHD pathogenesis. Our hypothesis shed light on the evidence based knowledge translation of plausible cellular phenomena due to vitamin D/VEGF homeostasis during valvular vandalism in RHD. PMID- 27692168 TI - Does bilirubin prevent hepatic steatosis through activation of the PPARalpha nuclear receptor? AB - Several large population studies have demonstrated a negative correlation between serum bilirubin levels and the development of obesity, hepatic steatosis, and cardiovascular disease. Despite the strong correlative data demonstrating the protective role of bilirubin, the mechanism by which bilirubin can protect against these pathologies remains unknown. Bilirubin has long been known as a powerful antioxidant and also has anti-inflammatory actions, each of which may contribute to the protection afforded by increased levels. We have recently described a novel function of bilirubin as a ligand for the peroxisome proliferator-activated receptor-alpha (PPARalpha), which we show specifically binds to the nuclear receptor. Bilirubin may function as a selective PPAR modulator (SPPARM) to control lipid accumulation and blood glucose. However, it is not known to what degree bilirubin activation of PPARalpha is responsible for the protection afforded to reduce hepatic steatosis. We hypothesize that bilirubin, acting as a novel SPPARM, increases hepatic fatty acid metabolism through a PPARalpha-dependent mechanism which reduces hepatic lipid accumulation and protects against hepatic steatosis and non-alcoholic fatty liver disease (NAFLD). PMID- 27692171 TI - Exosomes are possibly used as a tool of immune regulation during the dendritic cell-based immune therapy against HIV-I. AB - Dendritic cell (DC)-based immune therapy (IT) against HIV showed variable results. It is known that different factors influence host response to DC-IT. Exosomes derived from DC are regulators of the immune system. In this context, here we hypothesize about the role of the DC-derived exosomes on the DC-IT response. Based on data from RT-PCR array genes expression (focused on the TSG101 gene, an exosome marker) and flow cytometry experiments of a DC-IT against HIV-1 clinical trial, we hypothesize that: During the DC-IT exosomes are used as an additional tool for immune system modulation. In addition, we believe that a low release of exosomes can be more beneficial for the DC-IT response than a high release of exosomes. Our data reinforce the concept that exosomes can act as an immune regulatory tool, however not in a generalized manner, but in a highly precise way. Our hypothesis is based in preliminary experimental data, thus, it should be tested using experimental and functional strategies involving a great number of patients. Once the hypothesis confirmed, the immunomodulatory role of the exosomes during DC-IT must be considered as an important factor in the (I) evaluation, (II) modulation, and (III) success of DC-IT against HIV. PMID- 27692172 TI - Cognitive training and Bacopa monnieri: Evidence for a combined intervention to alleviate age associated cognitive decline. AB - As the elderly population grows the impact of age associated cognitive decline as well as neurodegenerative diseases such as Alzheimer's disease and dementia will increase. Ageing is associated with consistent impairments in cognitive processes (e.g., processing speed, memory, executive function and learning) important for work, well-being, life satisfaction and overall participation in society. Recently, there has been increased effort to conduct research examining methods to improve cognitive function in older citizens. Cognitive training has been shown to improve performance in some cognitive domains; including memory, processing speed, executive function and attention in older adults. These cognitive changes are thought to be related to improvements in brain connectivity and neural circuitry. Bacopa monnieri has also been shown to improve specific domains of cognition, sensitive to age associated cognitive decline (particularly processing speed and memory). These Bacopa monnieri dependent improvements may be due to the increase in specific neuro-molecular mechanisms implicated in the enhancement of neural connections in the brain (i.e. synaptogenesis). In particular, a number of animal studies have shown Bacopa monnieri consumption upregulates calcium dependent kinases in the synapse and post-synaptic cell, crucial for strengthening and growing connections between neurons. These effects have been shown to occur in areas important for cognitive processes, such as the hippocampus. As Bacopa monnieri has shown neuro-molecular mechanisms that encourage synaptogenesis, while cognitive training enhances brain connectivity, Bacopa monnieri supplementation could theoretically enhance and strengthen synaptic changes acquired through cognitive training. Therefore, the current paper hypothesises that the combination of these two interventions could improve cognitive outcomes, over and above the effects of administrating these interventions independently, as an effective treatment to ameliorate age associated cognitive decline. PMID- 27692173 TI - Highly purified calf hemodialysate (Actovegin(r)) may improve endothelial function by activation of proteasomes: A hypothesis explaining the possible mechanisms of action. AB - Highly purified calf hemodialysate (HPCH) known as Actovegin(r) or Solcoseryl(r) is one of the most controversial drugs currently marketed worldwide. It is not registered as drug in some countries and therefore its medical use there is illegal, while in others it is often among the top 10 of the best-selling medications. It could be also found in the list of the "most useless drugs" and was banned for short time by World Anti-Doping Agency as performance enhancer. However, the degree of its usefulness or uselessness remains unclear and there is not enough convincing data to make reliable conclusions. HPCH is claimed to have wound/muscular injuries healing, neuroprotective and antioxidant properties, to enhance glucose uptake and oxygen consumption, and possibly to improve performance of athletes. Since HPCH consists of over 200 naturally occurring substances which potentially may exert some pharmacological effects, it is extremely difficult to perform pharmacokinetic and pharmacodynamical studies. In this paper we have analyzed the available literature concerning clinical evidence, in vitro, ex vivo and in vivo effects of HPCH. Based on these data we suggest that the main target of the drug may be endothelium and improvement of endothelial function may be responsible for numerous largely nonspecific effects. We also propose the improvement of protein quality control by the means of activation of ubiquitin-proteasomal system as the most important biochemical mechanism responsible for its effects. The role of sphingolipids as potential proteasome-activators is extensively discussed. The effects of HPCH may also include direct or indirect ones on NF-kB-, Nrf2- and FOXO-mediated regulation of metabolic processes in the cells, which result in improved protein quality control, enhanced energy metabolism and increased resistance to oxidative stress. PMID- 27692174 TI - Sensing the Environment Through Sestrins: Implications for Cellular Metabolism. AB - Sestrins are a family of stress-responsive genes that have evolved to attenuate damage induced by stress caused to the cell. By virtue of their antioxidant activity, protein products of Sestrin genes prevent the accumulation of reactive oxygen species within the cell, thereby attenuating the detrimental effects of oxidative stress. In parallel, Sestrins participate in several signaling pathways that control the activity of the target of rapamycin protein kinase (TOR). TOR is a crucial sensor of intracellular and extracellular conditions that promotes cell growth and anabolism when nutrients and growth factors are abundant. In addition to reacting to stress-inducing insults, Sestrins also monitor the changes in the availability of nutrients, which allows them to serve as a key checkpoint for the TOR-regulated signaling pathways. In this review, we will discuss how Sestrins integrate signals from numerous stress- and nutrient-responsive signaling pathways to orchestrate cellular metabolism and support cell viability. PMID- 27692175 TI - Roles and Regulation of Epithelial Splicing Regulatory Proteins 1 and 2 in Epithelial-Mesenchymal Transition. AB - The transformation of polarized epithelial cells into cells with mesenchymal characteristics by the morphogenetic process of epithelial-mesenchymal transition (EMT) is a well-characterized process essential for embryonic development and associated with cancer progression. EMT is a program driven by changes in gene expression induced by several EMT-specific transcription factors, which inhibit the expression of cell-cell adhesion proteins and other epithelial markers, causing a characteristic loss of cell-cell adhesion, a switch to mesenchymal cell morphology, and increased migratory capabilities. Recently, it has become apparent that in addition to these transcriptionally regulated changes, EMT may also be regulated posttranscriptionally, that is, by alternative splicing. Specifically, the epithelial splicing regulatory proteins 1 and 2 (ESRP1 and ESRP2) have been described as epithelial-specific splicing master regulators specifically involved in EMT-associated alternative splicing. Here, we discuss the regulation of ESRP activity, as well as the evidence supporting a causal role of ESRPs in EMT. PMID- 27692177 TI - The Process of Cornification Evolved From the Initial Keratinization in the Epidermis and Epidermal Derivatives of Vertebrates: A New Synthesis and the Case of Sauropsids. AB - During land adaptation of the integument in tetrapods, an efficient stratum corneum was originated through the evolution of numerous corneous proteins in addition to the framework of intermediate filament-keratins present in keratinocytes. The new genes for corneous proteins were originated in a chromosome region indicated as epidermal differentiation complex (EDC), a locus with no apparent relationship to keratin genes. The addition of EDC proteins to IF-keratins transformed the process of epidermal keratinization present in anamniotes into a new process of cornification in the epidermis and skin appendages of amniotes, including hairs and feathers. In sauropsids among other EDC proteins a peculiar type of small proteins evolved a central region of 34 amino acids conformed as beta-sheets that, differently from the other EDC proteins, allowed the formation of long polymers of filamentous proteins customarily termed beta-keratins but in the present review reclassified as EDC corneous beta proteins. To the initial beta-sheets present in the corneous beta proteins specific N- and C-regions were later added in the proteins of different sauropsids in relation to the evolution of the corneous layer and skin appendages. Cornification contributed to the evolutive success of amniotes in the terrestrial environment. PMID- 27692178 TI - The Calcium-Sensing Receptor in Health and Disease. AB - The extracellular calcium-sensing receptor (CaSR) is a unique G protein-coupled receptor (GPCR) activated by extracellular Ca2+ and by other physiological cations including Mg2+, amino acids, and polyamines. CaSR is the most important master controller of the extracellular Ca2+ homeostatic system being expressed at high levels in the parathyroid gland, kidney, gut and bone, where it regulates parathyroid hormone (PTH) secretion, vitamin D synthesis, and Ca2+ absorption and resorption, respectively. Gain and loss of function mutations in the CaSR are responsible for severe disturbances in extracellular Ca2+ metabolism. CaSR agonists (calcimimetics) and antagonists (calcilytics) are in use or under intense research for treatment of hyperparathyroidism secondary to kidney failure and hypocalcemia with hypercalciuria, respectively. Expression of the CaSR extends to other tissues and systems beyond the extracellular Ca2+ homeostatic system including the cardiovascular system, the airways, and the nervous system where it may play physiological functions yet to be fully understood. As a consequence, CaSR has been recently involved in different pathologies including uncontrolled blood pressure, vascular calcification, asthma, and Alzheimer's disease. Finally, the CaSR has been shown to play a critical role in cancer either contributing to bone metastasis and/or acting as a tumor suppressor in some forms of cancer (parathyroid cancer, colon cancer, and neuroblastoma) and as oncogene in others (breast and prostate cancers). Here we review the role of CaSR in health and disease in calciotropic tissues and others beyond the extracellular calcium homeostatic system. PMID- 27692179 TI - Molecular Interactions Between Flowering Time and Abiotic Stress Pathways. AB - Plants have adapted to environmental changes and stresses over generations. The decision of transition from the vegetative to reproductive stage is critical, particularly under unfavorable conditions. Thus, plants appear to have developed mechanisms by which environmental factors or inputs are transmitted to stress response signaling pathways to confer tolerance and are simultaneously integrated into flowering regulation pathways (photoperiod, vernalization, autonomous, and gibberellic acid signaling) to propagate the next generation. In this review, we summarize how abiotic stresses influence, induce, or delay flowering time, particularly in the long-day plant Arabidopsis. Four major modes including FLOWERING LOCUS C (FLC), CONSTANS (CO), DELLA, and GIGANTEA (GI), which serve as hubs that integrate stress signals for regulating flowering time, are introduced. GI, a mediator of the photoperiod floral pathway and circadian clock, is involved in various biological processes and thus controls stress response directly through interaction with stress-responsive components and indirectly through association with circadian clock components. PMID- 27692181 TI - A Mechanistic Approach to the Development of Gene Therapy for Chronic Pain. AB - Treatment of chronic pain has created a "silent epidemic," a term that describes the serious public health problem of the abuse of opioid painkillers and other prescription drugs. Conventional pharmacotherapy is limited by the loss of effectiveness in the long-term and by potentially lethal side effects. Efforts need to be focused on the development of nonpharmacological approaches. As significant progress is made in the viral vector technology, gene therapy involving recombinant viruses as vehicles may become a viable alternative for treatment of severe pain. Virus-based gene therapy has several advantages: (1) the transfer of a therapeutic gene to produce/release bioactive therapeutic molecules in a specific location in the nervous system thus minimizing the risks of off-target side effects, and (2) sustained long-term production of the therapeutic agent. This review compiles recently developed strategies for gene therapy targeting specific mechanisms of specific chronic pain conditions. A few successful studies on animal models of chronic pain have been translated to human clinical trials. PMID- 27692182 TI - Community-Based Methadone Maintenance in a Large Detention Center is Associated with Decreases in Inmate Recidivism. AB - Because it is not common in the U.S. for jails to allow inmates to continue opioid medications that have been started in the community, we aimed to assess whether inmates maintained on methadone showed different rates of recidivism, lengths of incarceration, and types of offenses than other incarcerated groups. We also analyzed rates of return to home clinics after release. In order to answer these questions this study used extant data from 960 adult inmates in a large metropolitan detention center who were in 1 of 4 groups: general population with no known substance use disorders, alcohol detoxification, methadone maintenance (MMT), and opioid detoxification. Recidivism was assessed for 1 year after release. Data were collected from medical screening forms and jail databases and included demographic variables, dates of admission and release, number of doses and total dosage of methadone if applicable, reason for incarceration, and the date of rebooking and nature of offense, if it occurred. There was a significant difference in time to rebooking, F (3956)=13.32, p=.00, with the MMT group taking longer to be rebooked (275.6 days) than the opioid (236.3 days) and alcohol detoxification groups (229.3 days), but not the general population group (286.2 days). Survival analysis indicated significantly better survival without rebooking in the MMT and general population groups than the alcohol and opioid detoxification groups. There also were differences in length of incarceration, F (3, 954)=9.02, p=.00, with the MMT group being incarcerated longer than other substance using groups; and in misdemeanor vs. felony rebooking offenses, chi2 [3]=31.29, p<.01, with the opioid detoxification group being more likely to have a felony rebooking than the general or alcohol groups. In a separate analysis, data from 137 MMT clients, who were not precisely the same clients who were involved in other analyses reported in this article, indicated that over 97% returned to their home methadone clinics after incarceration. In summary, inmates who had been allowed to be maintained on methadone started in the community displayed a significantly longer time to be rearrested than inmates undergoing opioid or alcohol detoxification, but not inmates without substance use disorders. When they were rebooked, they were as likely as the opioid detoxification group to be rearrested for felony offenses. PMID- 27692183 TI - Primary Care Providers' Interest in Using a Genetic Test to Guide Alcohol Use Disorder Treatment. AB - BACKGROUND: Efforts to identify genetic moderators of pharmacotherapy response have generated interest in clinical applications of pharmacogenetic tests in alcohol use disorder (AUD) treatment. To date, no research on providers' interest in using pharmacogenetic tests in the context of AUD treatment has been reported. We conducted qualitative interviews with primary care providers from 5 clinics in the Veterans Health Administration (VA) to assess their interest in using a hypothetical genetic test to inform treatment of AUD with pharmacotherapy. METHODS: Key contacts were used to recruit 24 providers from 5 primary care clinics associated with a single large VA medical facility. Participants completed 30-minute in-person semi-structured interviews focused on barriers and facilitators to provision of pharmacotherapy for AUD. Interviews included a hypothetical scenario regarding the availability of a genetic test to inform AUD pharmacotherapy provision and/or selection. Provider responses to the hypothetical scenario were recorded, transcribed and analyzed qualitatively using inductive content analysis. Data were independently coded by three investigators, and themes were identified via consensus. RESULTS: Participants were generally interested in a genetic test to aid in AUD treatment planning. Five common themes were identified, including: perceived benefits of a pharmacogenetic test (e.g., aiding with therapeutic choice, positively impacting patient motivation for and engagement with AUD treatment), perceived drawbacks (e.g., limiting potential benefits of pharmacotherapy by reducing the target population for its receipt, adverse impacts of "negative" results), caveats to clinical utility (e.g., utility would depend on prognostic accuracy and/or medication characteristics), uncertainty as to whether such a test would impact clinical decision-making, and pragmatic barriers to use (costs and other resources, such as laboratory facilities). CONCLUSIONS: Primary care providers in this study generally believed a genetic test to aid in AUD treatment planning would be useful, due to its potential to hone treatment choice as well as to influence patient motivation and adherence to treatment. However, providers acknowledged that a test's utility would depend on the strength of its prognostic characteristics, its other benefits relative to standard care, and lack of pragmatic barriers. PMID- 27692176 TI - Orchestrating Lymphocyte Polarity in Cognate Immune Cell-Cell Interactions. AB - The immune synapse (IS) is a specialized structure established between different immune cells that fulfills several functions, including a role as a communication bridge. This intimate contact between a T cell and an antigen-presenting cell promotes the proliferation and differentiation of lymphocytes involved in the contact. T-cell activation requires the specific triggering of the T-cell receptor (TCR), which promotes the activation of different signaling pathways inducing the polarization of the T cell. During this process, different adhesion and signaling receptors reorganize at specialized membrane domains, concomitantly to the polarization of the tubulin and actin cytoskeletons, forming stable polarization platforms. The centrosome also moves toward the IS, driving the movement of different organelles, such as the biosynthetic, secretory, degrading machinery, and mitochondria, to sustain T-cell activation. A proper orchestration of all these events is essential for T-cell effector functions and the accomplishment of a complete immune response. PMID- 27692180 TI - Metabolic Regulation of Apoptosis in Cancer. AB - Apoptosis is a cellular suicide program that plays a critical role in development and human diseases, including cancer. Cancer cells evade apoptosis, thereby enabling excessive proliferation, survival under hypoxic conditions, and acquired resistance to therapeutic agents. Among various mechanisms that contribute to the evasion of apoptosis in cancer, metabolism is emerging as one of the key factors. Cellular metabolites can regulate functions of pro- and antiapoptotic proteins. In turn, p53, a regulator of apoptosis, also controls metabolism by limiting glycolysis and facilitating mitochondrial respiration. Consequently, with dysregulated metabolism and p53 inactivation, cancer cells are well-equipped to disable the apoptotic machinery. In this article, we review how cellular apoptosis is regulated and how metabolism can influence the signaling pathways leading to apoptosis, especially focusing on how glucose and lipid metabolism are altered in cancer cells and how these alterations can impact the apoptotic pathways. PMID- 27692184 TI - Smoking Cessation and Adolescent Treatment Response With Comorbid ADHD. AB - Minors entering treatment for alcohol and other drug (AOD) use disorders tend to smoke at high rates, and many have comorbid attention deficit hyperactivity disorder (ADHD). Clear-air laws force patients to refrain from smoking on the premises of AOD treatment facilities, which may hinder the progress of treatment seeking populations who smoke and struggle with ADHD comorbidity in particular. This study explores clinical characteristics associated with smoking among youths presenting for residential treatment, clinical characteristics associated with smoking cessation, and the impact of smoking cessation with ADHD comorbidity on AOD treatment response. Participants were 195 adolescents (52% female, aged 14-18 years) court-referred to residential treatment. Data were collected at intake, prospectively each week for the 10-week treatment period, and at discharge. Two thirds (67%) of the enrollment sample entered treatment smoking half a pack a day on average, a large proportion (50%) of which did not smoke during treatment. ADHD patients were more likely to smoke before and during treatment except for those who got active in service and step-work. Quitting smoking did not adversely affect AOD outcomes and was associated with better prognosis of lowered AOD cravings for youths with and without ADHD. Smoking cessation during adolescent AOD treatment is recommended with provision of pharmaceutical and/or behavioral modalities that reduce nicotine withdrawal. PMID- 27692185 TI - The Alcohol Intervention Mechanisms Scale (AIMS): Preliminary Reliability and Validity of a Common Factor Observational Rating Measure. AB - The present work provides an overview, and pilot reliability and validity for the Alcohol Intervention Mechanisms Scale (AIMS). The AIMS measures therapist interventions that occur broadly across modalities of behavioral treatment for alcohol use disorder. It was developed based on identified commonalities in the function rather than content of therapist interventions in observed therapy sessions, as well as from existing observer rating systems. In the AIMS, the primary function areas are: explore (four behavior count codes), teach (five behavior count codes), and connect (three behavior count codes). Therapist behavior counts provide a frequency rating of occurrence (i.e., adherence). The three functions (explore, teach, connect) are then rated on global skillfulness, which provides a quality valence (i.e., competence) to the entire session. In the present study, three independent raters received roughly 30 hours of training on the use of the AIMS by the first author. Data were a sample of therapy session audio files from a Project MATCH clinical research site. Reliability results showed generally good performance for the measure. Specifically, 2-way mixed intraclass coefficients were 'excellent', ranging from .94 to .99 for function summary scores, while prevalence-adjusted, bias-adjusted kappa for global skillfulness measures were in the 'fair' to 'moderate' range (k=.36 to.40). Internal consistency reliability was acceptable, as were preliminary factor models by behavioral treatment function (i.e., explore, teach, connect). However, confirmatory fit for the subsequent three factor model was poor. In concurrent validity analyses, AIMS summary and skillfulness scores showed associations with relevant Project MATCH criterion measures (i.e., MATCH Tape Rating Scale) that were consistent with expectations. The AIMS is a promising and reliable observational measure of three proposed common functions of behavioral alcohol treatment. PMID- 27692186 TI - A survey of Physicians' Perspectives on the New York State Mandatory Prescription Monitoring Program (ISTOP). AB - BACKGROUND: Prescription drug monitoring programs (PDMPs) have emerged as one tool to combat prescription drug misuse and diversion. New York State mandates that prescribers use its PDMP (called ISTOP) before prescribing controlled substances. We surveyed physicians to assess their experiences with mandatory PDMP use. METHODS: Electronic survey of attending physicians, from multiple clinical specialties, at one large urban academic medical center. RESULTS: Of 207 responding physicians, 89.4% had heard of ISTOP, and of those, 91.1% were registered users. 45.7% of respondents used the system once per week or more. There was significant negative feedback, with 40.4% of respondents describing ISTOP as "rarely" or "never helpful," and 39.4% describing it as "difficult" or "very difficult" to use. Physicians expressed frustration with the login process, the complexity of querying patients, and the lack of integration with electronic medical records. Only 83.1% knew that ISTOP use is mandated in almost all situations. A minority agreed with this mandate (44.2%); surgeons, males, and those who prescribe controlled substances at least once per week had significantly lower rates of agreement (22.6%, 36.2%, and 33.0%, respectively). The most common reasons for disagreement were: time burden, concerns about helpfulness, potential for under-treatment, and erosion of physician autonomy. Emergency physicians, who are largely exempt from the mandate, were the most likely to believe that ISTOP was helpful, yet the least likely to be registered users. 48.4% of non-emergency physicians reported perfect compliance with the mandate; surgeons and males reported significantly lower rates of perfect compliance (18.2% and 36.8%, respectively). CONCLUSIONS: This study offers a unique window into how one academic medical faculty has experienced New York's mandatory PDMP. Many respondents believe that ISTOP is cumbersome and generally unhelpful. Furthermore, many disagree with, and don't comply with, its mandatory use. PMID- 27692187 TI - Staff Perceptions of Substance Use Disorder Treatment in VA Primary Care-Mental Health Integrated Clinics. AB - INTRODUCTION: Guidelines recommend that substance use disorder (SUD) treatment be available in primary care-mental health integrated clinics, which offer mental and behavioral health assessment and treatment in the primary care setting. Despite this recommendation it is unclear what barriers and facilitators exist to SUD treatment being provided in that setting. This work sought to understand current SUD services in such integrated clinics, explore other services may that be appropriate, and identify barriers to such services. METHODS: We conducted qualitative interviews with 23 staff members from integrated clinics at 6 Veterans Affairs medical centers. We transcribed interviews and performed thematic analysis to identify emergent themes. RESULTS: We identified seven themes affecting staff experience and ability to provide SUD services in the integrated clinic: clinical effectiveness, clinical requirements, regulatory requirements, program goals, proximity of the integrated clinic and SUD services, training on substance use disorder, and role specialization. CONCLUSIONS: VA primary care-mental health integrated clinic staff members do not currently view SUD treatment as the focus of their work, but are open to offering SUD treatment including brief psychological interventions or medication. Several barriers to providing SUD treatment were identified, including the need for additional staff training around appropriate interventions for the integrated clinic setting, additional staffing and space, and a structured implementation strategy to promote the use of SUD treatments. PMID- 27692188 TI - A Naturalistic Evaluation of Extended-Release Naltrexone in Clinical Practice in Missouri. AB - The purpose of this study was to compare the naturalistic outcomes of individuals with alcohol or opioid use problems who were treated with extended-release naltrexone (XR-NTX) to those treated with psychosocial treatment only and also to those treated with other medication-assisted therapies in Missouri during 2010 to 2011. We analyzed intake and discharge data collected as part of SAMHSA's Treatment Episode Data Set assessments. Patients who received XR-NTX during their treatment episode were compared, for those reporting alcohol (but not opioids) as their problem (N=21,137), to those who received oral naltrexone, acamprosate, and psychosocial treatment only, and for those who reported opioids as a problem (N=8996), to those receiving oral naltrexone, buprenorphine/naloxone, and psychosocial treatment only. Group differences were adjusted using propensity score weighting, with propensity scores derived from 18 intake variables. For the alcohol sample, patients who received XR-NTX vs. the oral naltrexone group had superior composite outcomes on a measure combining abstinence, self-help participation, employment, and arrests. For the opioid sample, XR-NTX was found to have significantly better outcomes than oral naltrexone on the composite outcome measure. For both the alcohol and opioid samples, the group that received XR-NTX stayed in treatment longer vs. psychosocial treatment only. In the opioid sample, those receiving buprenorphine/naloxone remained in treatment longer than those receiving XR-NTX. PMID- 27692189 TI - Monitoring a Prison Opioid Treatment Program Over a Period of Change to Clinical Governance Arrangements, 2007-2013. AB - BACKGROUND AND AIMS: Opioid substitution therapy (OST) is an effective treatment for opioid dependence that is provided in many correctional settings, including New South Wales (NSW), Australia. In 2011, changes to the clinical governance of the NSW prison OST program were implemented, including a more comprehensive assessment, additional specialist nurses, and centralization of program management and planning. This study aimed to document the NSW prison OST program, and assess the impact of the enhanced clinical governance arrangements on retention in treatment until release, the provision of an OST prescription to patients at release, and presentation to a community OST clinic within 48 hours of release from custody. METHOD: Data from the NSW prison OST program were obtained for the calendar years 2007-2013. Outcomes were analyzed quarterly using log binomial segmented regression. RESULTS: 8577 people were treated with OST in NSW correctional centers, 2007-2013. Over the entire study period, patients were retained in OST until release in 82% of treatment episodes; a prescription for OST was able to be arranged prior to release in 90% of releases; and patients presented to a community clinic within 48 hours of release in 94% of releases with prescriptions. Following the introduction of the changes to clinical governance, there was a significant increasing trend in retention in OST until release, and in provision of an OST prescription at release. There was an initial increase, followed by a decreasing trend, in presentation to a community clinic within 48 hours of release. DISCUSSION: This large prison-based OST program has high rates of retention in treatment and continuity of care as patients transition from custody to the community. Strengthened clinical governance arrangements were associated with increased retention in treatment until release and increased provision of an OST prescription at release, but did not improve clinic attendance following release from custody. PMID- 27692190 TI - Transitioning From Detoxification to Substance Use Disorder Treatment: Facilitators and Barriers. AB - Although successful transitions from detoxification to substance use disorder treatment are associated with improved outcomes, many detoxification patients do not initiate treatment. This qualitative study informs detoxification and addiction treatment providers, and health systems, about how to improve detoxification to treatment transitions, by reporting detoxification providers' views of transition facilitators and barriers. The sample consisted of 30 providers from 30 Veterans Health Administration detoxification programs. Themes regarding transition facilitators and barriers emerged at the patient, program (detoxification programs, and addiction programs), and system levels. Detoxification program-level practices of discharge planning, patient education, and rapport building were reported as facilitating the transition to treatment. Six themes captured transition facilitators within addiction treatment programs: the provision of evidence-based practices, patient-centered care, care coordination, aftercare, convenience, and a well-trained and professional staff. This study expands previous literature on detoxification and addiction treatment by systematically and qualitatively examining factors that promote and hinder treatment initiation after inpatient and outpatient detoxification, from a provider perspective, in an era of health care reform and expanded substance use disorder treatment. PMID- 27692191 TI - Semantic Networks, Schema Change, and Reincarceration Outcomes of Therapeutic Community Graduates. AB - BACKGROUND: Therapeutic community (TC) clinical theory assumes that peer interaction forms a framework for social learning that will displace ingrained cognitive schema that underlie substance abuse. There has been no direct test of this hypothesis. METHODS: We analyzed the content of a large corpus of written affirmations (pushups) and corrections (pull-ups) exchanged between 2342 male TC graduates. We encoded the content of the written communications as semantic networks of words, in which words that appear in the same brief document are connected and are referred to as word combinations. Loss of combinations and gain of combinations each measured an aspect of change in word combination patterns across time. These measures were used in a multivariable Cox model to predict the hazard of reincarceration for residents while controlling for race, age, score on the Level of Service Inventory-Revised and the total number of pushups and pull ups sent to peers. RESULTS: Residents' reincarceration risk varied significantly with changes in word combinations used over the course of treatment. The implications of the model were visualized to reveal the complicated nature of the interaction terms included in the model. The visuals suggested that residents who changed their expression patterns the least - lost and gained few word combinations - had the highest reincarceration risk after graduation. CONCLUSIONS: The results suggest that TC success, in terms of increasing time to reincarceration, depends on how residents change their interaction patterns through the treatment process. Merely interacting with others does not explain success; but whether those interactions change does explain outcomes, which may imply that more fundamental changes are occurring. PMID- 27692193 TI - Non-Prescribed Buprenorphine in New York City: Motivations for Use, Practices of Diversion, and Experiences of Stigma. AB - Non-medical use of opioid analgesics (OAs) has increased in the United States over the past decade. Concurrently, access to opioid agonist therapies (OATs) such as buprenorphine has expanded. However, there has been little in-depth qualitative exploration into circumstances surrounding buprenorphine diversion and non-prescribed use. This study reports on qualitative data from in-depth interviews conducted with persons in New York City reporting non-medical OA use in the past 12 months. Participants (n=42) were aged between 18 and 49 years. The majority were male (n=29) and non-Hispanic White (n=35). All participants self reported physical opioid dependence. Motivations for non-prescribed buprenorphine use included the abatement of withdrawal symptoms or a self-initiated detoxification or treatment plan. Few participants reported buprenorphine use for euphoric effect, and no participants reported using buprenorphine as a primary drug. Buprenorphine diversion primarily occurred as a means of supporting ongoing illicit drug use, and no participants reported selling buprenorphine as a primary source of income. Participants reported misinformation around some key areas of buprenorphine induction and use, as well as stigma within peer networks and from drug treatment providers. As access to buprenorphine treatment continues to expand in the United States, enhancing patient education is a critical step toward minimizing diversion and incidental harms from non-prescribed use. PMID- 27692192 TI - Mortality Rates Among Substance Use Disorder Participants in Clinical Trials: Pooled Analysis of Twenty-Two Clinical Trials Within the National Drug Abuse Treatment Clinical Trials Network. AB - BACKGROUND: Most substance use disorders (SUD) treatment clinical trials are too short and small to reliably estimate the incidence of rare events like death. OBJECTIVE: The aim of this study is to estimate the overall mortality rates among a SUD treatment-seeking population by pooling participants from multiple clinical trials conducted through the National Institute on Drug Abuse (NIDA)-sponsored National Drug Abuse Treatment Clinical Trials Network (CTN). PARTICIPANTS: Drug and or alcohol users (N=9866) who sought treatment and participated in one of the twenty-two CTN trials. MEASUREMENTS: Data were collected through randomized clinical trials in national community treatment programs for SUD. Pooled analysis was performed to assess age- and gender-standardized mortality rate(s) (SM rate(s)), and mortality ratio(s) (SM ratio(s)) of CTN trial participants compared to the U.S. general population. RESULTS: The age- and gender-SM rate among CTN trials participants was 1403 (95% CI: 862-2074) per 100,000 person years (PY) compared to 542 (95% CI: 541-543) per 100,000 PY among the U.S. general population in 2005. By gender, age-adjusted SM ratio for female CTN trial participants was over five times (SM ratio=5.35, 95% CI: 3.31-8.19)), and for male CTN trial participants, it was over three times (SM ratio=3.39, 95% CI: 2.25 4.90) higher than their gender comparable peers in the U.S. general population. CONCLUSIONS: Age and gender-standardized mortality rates and ratios among NIDA CTN SUD treatment-seeking clinical trial participants are higher than the age and gender comparable U.S. general population. The overall mortality rates of CTN trial participants are similar to in-treatment mortality reported in large U.S. and non-U.S. cohorts of opioid users. Future analysis with additional CTN trial participants and risk times will improve the stability of estimates, especially within subgroups based on primary substance of abuse. These SUD mortality rates can be used to facilitate safety monitoring within SUD clinical trials. PMID- 27692194 TI - Presence of Drug-Free Family and Friends in the Personal Social Networks of People Receiving Treatment for Opioid Use Disorder. AB - The present study evaluated the presence of drug-free family and friends in the personal social networks of individuals seeking treatment for opioid use disorder, and the willingness of patients to bring these individuals to the treatment program to support recovery efforts. Patients at a community medication assisted treatment program (n=355) completed a clinical survey to identify drug free social network members. Results showed that almost all patients (98%) reported having at least one drug-free family or friend in their personal network (M=3.7), and that these network members often lived in relatively close proximity to the patient (M distance of closest member =1.8 miles). About a quarter of these individuals (26%) had a history of substance use problems, with 10% of the entire sample currently receiving treatment for a substance use problem. Rates of drug-free network members varied across several baseline characteristics. Most patients (89%) reported a willingness to invite at least one drug-free network member into treatment to support recovery efforts. Mobilizing drug-free network family and friends may provide a pathway to help individuals with substance use disorders access and benefit from community support. PMID- 27692195 TI - The History of Sympathetic Surgery. AB - At present, primary hyperhidrosis is the main indication for sympathectomy. For upper thoracic sympathetic ablation, excision of the second thoracic ganglion alone or with the first and/or third ganglia was the standard during the open surgery era. With the advent of thoracoscopy, modifications related to the level, extent, and type of ablation were proposed to attenuate compensatory hyperhidrosis. The ideal operation for sympathetic denervation of the face and upper limbs remain to be defined. Controlled double-blind studies with quantitave measurements of sweat production are required. PMID- 27692196 TI - Pathophysiology of Hyperhidrosis. AB - Studies and case reports on excessive sweating frequently state that hyperhidrosis is a disease whose origin and mechanism are unknown. However, the term excessive is rarely based on systematic diagnostic measurements, instead being a description of the symptoms from patient histories, which suggests that hyperhidrosis is purely a problem involving the quantity of sweat, whereas it is a change in the control mechanism of sweating in which the need for and production of sweat are strongly disproportionate. This lack of proportion is perceived by those affected to be a limitation of activities of daily living and is thus pathologic. PMID- 27692197 TI - Emerging Nonsurgical Treatments for Hyperhidrosis. AB - A variety of available treatment options are available for primary focal hyperhidrosis, and some can be combined to obtain maximum effective results. Most treatment options have only been studied in patients with axillary hyperhidrosis, and more studies are needed to develop therapies for other body regions. Several clinical trials are underway with promising preliminary results; however, there is still a large need for new therapies. PMID- 27692198 TI - Selecting the Right Patient for Surgical Treatment of Hyperhidrosis. AB - This article presents a personal view of the indications for surgical treatment of patients with hyperhidrosis based on long clinical experience. Endoscopic thoracic sympathectomy is the preferred opinion for palmar sweating. It is also useful when there is additional axillary sweating but is not the first choice for isolated armpit symptoms. Surgical treatment of craniofacial sweating is much more likely to be followed by undesirable side-effects.

AB - Large case series and randomized trials over the past 25 years have consistently demonstrated thoracoscopic interruption of the sympathetic chain to be a safe and effective treatment of focal primary hyperhidrosis. The surgical technique has evolved toward less-invasive and less-extensive procedures in an effort to minimize perioperative morbidity and effectively balance postoperative compensatory sweating with symptomatic relief. This review summarizes available evidence regarding the surgical approach and the optimal level of interruption of the sympathetic chain based on a patient's presenting distribution of pathologic sweating. PMID- 27692200 TI - Reversibility of Sympathectomy for Primary Hyperhidrosis. AB - Endoscopic thoracic sympathectomy (ETS) is an effective treatment of primary hyperhidrosis of the face, upper extremities, and axillae. The major limitation is the side effect of compensatory sweating severe enough that patients request reversal in up to 10% of cases. When ETS is performed by cutting the sympathetic chain, reversal requires nerve grafting. However, for ETS done with clips, reversal is a simple thoracoscopic outpatient procedure of removing the clips. Subsequent reversal of the sympathectomy, ie, nerve regeneration, is successful in many cases. However, follow-up is short. Factors contributing to success rates require further study. PMID- 27692201 TI - Reconstruction of the Sympathetic Chain. AB - There is a small subset of patients who have undergone endoscopic thoracic sympathectomy for hyperhidrosis or facial blushing who are dissatisfied and would wish reversal. Compensatory sweating is the most common side effect that causes a person to regret surgery. Treatment options are limited and usually not effective in patients with severe side effects from sympathectomy. Nerve graft interposition has been proven to be effective in experimental models and small clinical series. Da Vinci robotic nerve graft reconstruction with interposition graft and direct suturing of nerve and high magnification dissection most closely mirrors standard nerve reconstruction principles when done as a minimally invasive procedure. PMID- 27692202 TI - Quality of Life Changes Following Surgery for Hyperhidrosis. AB - The best way to evaluate the impact of primary hyperhidrosis on quality of life (QL) is through specific questionnaires, avoiding generic models that do not appropriately evaluate individuals. QL improves significantly in the short term after sympathectomy. In the longer term, a sustained and stable improvement is seen, although there is a small decline in the numbers; after 5 and even at 10 years of follow-up it shows virtually the same numerical distribution. Compensatory hyperhidrosis is a major side effect and the main aggravating factor in postoperative QL, requiring attention to its management and prevention. PMID- 27692203 TI - Management of Compensatory Sweating After Sympathetic Surgery. AB - Compensatory hyperhidrosis (HH) is the most common and feared side effect of thoracic sympathectomy, because patients with severe forms have their quality of life greatly impaired. The most well-known factors associated with compensatory HH are extension of manipulation of the sympathetic chain, level of sympathetic denervation, and body mass index. Technical developments as well as the proper selection of patients for surgery have been crucial in reducing the occurrence of severe forms of compensatory HH. Therapeutic options include topical agents, botulinum toxin, systemic anticholinergics, clip removal, and sympathetic chain reconstruction, although the efficacy is not well-established for all the methods. PMID- 27692204 TI - Less Common Side Effects of Sympathetic Surgery. AB - Because of video-assisted thoracic technology and increased patient awareness of treatment options for palmar hyperhidrosis, endoscopic thoracic sympathectomy (ETS) has become a well-accepted treatment for this disorder. Video assistance affords excellent visualization of thoracic anatomy, which allows the procedure to be done quickly with few complications. However, despite the ease of performing ETS, complications can occur unless thoracic anatomy and physiology are well-understood. Awareness of possible intraoperative and postoperative complications is essential if this procedure is gong to be performed safely. PMID- 27692205 TI - Facial Blushing: Patient Selection and Long-Term Results. AB - Facial blushing, associated with social phobia, may have severe negative impact on the quality of daily life. The first line of treatment should be psychological and/or pharmacologic. In severe cases not responding to nonsurgical treatment, surgical sympathetic denervation is an option. A thorough disclosure of effects, complications, and side effects is mandatory and patient selection is crucial to obtain high patient satisfaction from surgical treatment. PMID- 27692206 TI - Management of Plantar Hyperhidrosis with Endoscopic Lumbar Sympathectomy. AB - Primary plantar hyperhidrosis is defined as excessive secretion of the sweat glands of the feet and may lead to significant limitations in private and professional lifestyle and reduction of health-related quality of life. Conservative therapy measures usually fail to provide sufficient relieve of symptoms and do not allow long-lasting elimination of hyperhidrosis. Endoscopic lumbar sympathectomy appears to be a safe and effective procedure for eliminating excessive sweating of the feet and improves quality of life of patients with severe plantar hyperhidrosis. PMID- 27692207 TI - Hyperhidrosis. PMID- 27692208 TI - Graph-based inductive reasoning. AB - This article discusses methods of inductive inferences that are methods of visualizations designed in such a way that the "eye" can be employed as a reliable tool for judgment. The term "eye" is used as a stand-in for visual cognition and perceptual processing. In this paper "meaningfulness" has a particular meaning, namely accuracy, which is closeness to truth. Accuracy consists of precision and unbiasedness. Precision is dealt with by statistical methods, but for unbiasedness one needs expert judgment. The common view at the beginning of the twentieth century was to make the most efficient use of this kind of judgment by representing the data in shapes and forms in such a way that the "eye" can function as a reliable judge to reduce bias. The need for judgment of the "eye" is even more necessary when the background conditions of the observations are heterogeneous. Statistical procedures require a certain minimal level of homogeneity, but the "eye" does not. The "eye" is an adequate tool for assessing topological similarities when, due to heterogeneity of the data, metric assessment is not possible. In fact, graphical assessments precedes measurement, or to put it more forcefully, the graphic method is a necessary prerequisite for measurement. PMID- 27692209 TI - Structural realism beyond physics. AB - The main purpose of this paper is to test structural realism against (one example from) the historical record. I begin by laying out an existing challenge to structural realism - that of providing an example of a theory exhibiting successful structures that were abandoned - and show that this challenge can be met by the miasma theory of disease. However, rather than concluding that this is an outright counterexample to structural realism, I use this case to show why it is that structural realism, in its current form, has trouble dealing with theories outside physics. I end by making some concrete suggestions for structural realists to pursue if, indeed, they are serious about extending structural realism to other domains. PMID- 27692210 TI - Mechanistic explanation, cognitive systems demarcation, and extended cognition. AB - Approaches to the Internalism-Externalism controversy in the philosophy of mind often involve both (broadly) metaphysical and explanatory considerations. Whereas originally most emphasis seems to have been placed on metaphysical concerns, recently the explanation angle is getting more attention. Explanatory considerations promise to offer more neutral grounds for cognitive systems demarcation than (broadly) metaphysical ones. However, it has been argued that explanation-based approaches are incapable of determining the plausibility of internalist-based conceptions of cognition vis-a-vis externalist ones. On this perspective, improved metaphysics is the route along which to solve the Internalist-Externalist stalemate. In this paper we challenge this claim. Although we agree that explanation-orientated approaches have indeed so far failed to deliver solid means for cognitive system demarcation, we elaborate a more promising explanation-oriented framework to address this issue. We argue that the mutual manipulability account of constitutive relevance in mechanisms, extended with the criterion of 'fat-handedness', is capable of plausibly addressing the cognitive systems demarcation problem, and thus able to decide on the explanatory traction of Internalist vs. Externalist conceptions, on a case-by case basis. Our analysis also highlights why some other recent mechanistic takes on the problem of cognitive systems demarcation have been unsuccessful. We illustrate our claims with a case on gestures and learning. PMID- 27692211 TI - Kepler: Analogies in the search for the law of refraction. AB - This paper examines the methodology used by Kepler to discover a quantitative law of refraction. The aim is to argue that this methodology follows a heuristic method based on the following two Pythagorean principles: (1) sameness is made known by sameness, and (2) harmony arises from establishing a limit to what is unlimited. We will analyse some of the author's proposed analogies to find the aforementioned law and argue that the investigation's heuristic pursues such principles. PMID- 27692212 TI - Overlapping ontologies and Indigenous knowledge. From integration to ontological self-determination. AB - Current controversies about knowledge integration reflect conflicting ideas of what it means to "take Indigenous knowledge seriously". While there is increased interest in integrating Indigenous and Western scientific knowledge in various disciplines such as anthropology and ethnobiology, integration projects are often accused of recognizing Indigenous knowledge only insofar as it is useful for Western scientists. The aim of this article is to use tools from philosophy of science to develop a model of both successful integration and integration failures. On the one hand, I argue that cross-cultural recognition of property clusters leads to an ontological overlap that makes knowledge integration often epistemically productive and socially useful. On the other hand, I argue that knowledge integration is limited by ontological divergence. Adequate models of Indigenous knowledge will therefore have to take integration failures seriously and I argue that integration efforts need to be complemented by a political notion of ontological self-determination. PMID- 27692213 TI - Extensional scientific realism vs. intensional scientific realism. AB - Extensional scientific realism is the view that each believable scientific theory is supported by the unique first-order evidence for it and that if we want to believe that it is true, we should rely on its unique first-order evidence. In contrast, intensional scientific realism is the view that all believable scientific theories have a common feature and that we should rely on it to determine whether a theory is believable or not. Fitzpatrick argues that extensional realism is immune, while intensional realism is not, to the pessimistic induction. I reply that if extensional realism overcomes the pessimistic induction at all, that is because it implicitly relies on the theoretical resource of intensional realism. I also argue that extensional realism, by nature, cannot embed a criterion for distinguishing between believable and unbelievable theories. PMID- 27692214 TI - Carnap on unified science. AB - Unified science is a recurring theme in Carnap's work from the time of the Aufbau until the end of the 1930's. The theme is not constant, but knows several variations. I shall extract three quite precise formulations of the thesis of unified science from Carnap's work during this period: from the Aufbau, from Carnap's so-called syntactic period, and from Testability and Meaning and related papers. My main objective is to explain these formulations and to discuss their relation, both to each other and to other aspects of Carnap's work.

PMID- 27692216 TI - The re-emergence of hyphenated history-and-philosophy-of-science and the testing of theories of scientific change. AB - A basic premise of hyphenated history-and-philosophy-of-science is that theories of scientific change have to be based on empirical evidence derived from carefully constructed historical case studies. This paper analyses one such systematic attempt to test philosophical claims, describing its historical context, rationale, execution, and limited impact. PMID- 27692217 TI - The ontology of quantum field theory: Structural realism vindicated? AB - In this paper I elicit a prediction from structural realism and compare it, not to a historical case, but to a contemporary scientific theory. If structural realism is correct, then we should expect physics to develop theories that fail to provide an ontology of the sort sought by traditional realists. If structure alone is responsible for instrumental success, we should expect surplus ontology to be eliminated. Quantum field theory (QFT) provides the framework for some of the best confirmed theories in science, but debates over its ontology are vexed. Rather than taking a stand on these matters, the structural realist can embrace QFT as an example of just the kind of theory SR should lead us to expect. Yet, it is not clear that QFT meets the structuralist's positive expectation by providing a structure for the world. In particular, the problem of unitarily inequivalent representations threatens to undermine the possibility of QFT providing a unique structure for the world. In response to this problem, I suggest that the structuralist should endorse pluralism about structure. PMID- 27692218 TI - Looking forward, not back: Supporting structuralism in the present. AB - The view that the fundamental kind properties are intrinsic properties enjoys reflexive endorsement by most metaphysicians of science. But ontic structural realists deny that there are any fundamental intrinsic properties at all. Given that structuralists distrust intuition as a guide to truth, and given that we currently lack a fundamental physical theory that we could consult instead to order settle the issue, it might seem as if there is simply nowhere for this debate to go at present. However, I will argue that there exists an as-yet untapped resource for arguing for ontic structuralism - namely, the way that fundamentality is conceptualized in our most fundamental physical frameworks. By arguing that physical objects must be subject to the 'Goldilock's principle' if they are to count as fundamental at all, I argue that we can no longer view the majority of properties defining them as intrinsic. As such, ontic structural realism can be regarded as the most promising metaphysics for fundamental physics, and that this is so even though we do not yet claim to know precisely what that fundamental physics is. PMID- 27692219 TI - Structural realism versus deployment realism: A comparative evaluation. AB - In this paper I challenge and adjudicate between the two positions that have come to prominence in the scientific realism debate: deployment realism and structural realism. I discuss a set of cases from the history of celestial mechanics, including some of the most important successes in the history of science. To the surprise of the deployment realist, these are novel predictive successes toward which theoretical constituents that are now seen to be patently false were genuinely deployed. Exploring the implications for structural realism, I show that the need to accommodate these cases forces our notion of "structure" toward a dramatic depletion of logical content, threatening to render it explanatorily vacuous: the better structuralism fares against these historical examples, in terms of retention, the worse it fares in content and explanatory strength. I conclude by considering recent restrictions that serve to make "structure" more specific. I show however that these refinements will not suffice: the better structuralism fares in specificity and explanatory strength, the worse it fares against history. In light of these case studies, both deployment realism and structural realism are significantly threatened by the very historical challenge they were introduced to answer. PMID- 27692220 TI - A Modern Definition of the Athlete's Heart-for Research and the Clinic. AB - Exercise training can have a profound effect on cardiac structure. Recent evidence suggests that the greatest determinants of exercise-induced cardiac remodeling are the intensity, duration, and frequency of training. This also has overlap with athlete fitness. There are many additional factors that are important in determining cardiac remodeling, but while further refinements evolve, the authors argue that the best means of predicting the degree of expected physiologic remodeling is to either quantify training (intensity times total training time) or its by-product (exercise capacity). A uniform approach to estimating the degree of exercise-induced cardiac remodeling will enable more consistent research. PMID- 27692221 TI - Molecular Aspects of Exercise-induced Cardiac Remodeling. AB - Exercise-induced cardiac remodeling is typically an adaptive response associated with cardiac myocyte hypertrophy and renewal, increased cardiac myocyte contractility, sarcomeric remodeling, cell survival, metabolic and mitochondrial adaptations, electrical remodeling, and angiogenesis. Initiating stimuli/triggers of cardiac remodeling include increased hemodynamic load, increased sympathetic activity, and the release of hormones and growth factors. Prolonged and strenuous exercise may lead to maladaptive exercise-induced cardiac remodeling including cardiac dysfunction and arrhythmia. In addition, this article describes novel therapeutic approaches for the treatment of heart failure that target mechanisms responsible for adaptive exercise-induced cardiac remodeling, which are being developed and tested in preclinical models. PMID- 27692222 TI - Sudden Cardiac Death in Athletes: Still Much to Learn. AB - Athletes are often regarded as individuals at the pinnacle of health and fitness, nearly to the point of invincibility. The sudden cardiac death (SCD) of an athlete is therefore generally unexpected and extremely traumatic. Some of the most commonly identified causes of SCD in athletes include the genetic heart diseases. Despite thorough clinical and genetic investigation, in some cases a cause of death cannot be elucidated. Further research in these areas, spanning clinical, genetic, and public health perspectives, is required to help guide clinicians and those encountering the tragedy of SCD in an athlete.

PMID- 27692224 TI - Exercise-Induced Atrial Remodeling: The Forgotten Chamber. AB - Cardiac changes in athletes involve the left ventricle and atrium. Mild left atrial enlargement is common among competitive athletes, possibly a physiologic adaptation to exercise conditioning. The prevalence of this remodeling and the association with supraventricular arrhythmias has not been systematically addressed. Echocardiography screens for patients with disease involving the left atrium. New techniques like speckle tracking can recognize early atrial dysfunction and assess left atrial myocardial function in patients with either physiologic or pathologic left ventricular hypertrophy. This article reviews echocardiographic techniques in delineating the athlete's morphology and functional properties of the left atrium. PMID- 27692225 TI - Atrial Fibrillation in Endurance Athletes: From Mechanism to Management. AB - Exercise training has considerable health benefits. However, recent research has demonstrated a greater risk of atrial arrhythmias in endurance athletes. The mechanisms promoting atrial fibrillation in athletes are unclear but there seems to be a central role for atrial remodeling, accompanied by autonomic alterations and inflammation. Animal studies have provided unique insights, yet prospective human data are lacking. Treatment options seem to yield similar efficacy to that seen in a nonathletic population and may be justified as an early rhythm control strategy. Further studies are required to enhance understanding of the cardiac adaptations to intensive exercise training. PMID- 27692226 TI - Congenital Heart Disease and the Athlete: What We Know and What We Do Not Know. AB - Since outcomes for patients with congenital heart disease (CHD) have greatly improved, most patients with CHD are surviving into adulthood and creating dilemmas for practitioners with regard to competitive sports participation. Much time, effort, and expertise have gone into developing the new American Heart Association/American College of Cardiology's guidelines and the European Society of Cardiology's guidelines. Practitioners should consult the guidelines but also be aware of gaps in the literature and should individualize recommendations for each patient. Both participation and restriction decisions should be made thoughtfully and collaboratively with athletes as either decision carries important consequences." PMID- 27692227 TI - Exercise Prescription for the Athlete with Cardiomyopathy. AB - Inherited cardiomyopathies have highly variable expression in terms of symptoms, functional limitations, and disease severity. Associated risk of sudden cardiac death is also variable. International guidelines currently recommend restriction of all athletes with cardiomyopathy from participation in competitive sports. While the guidelines are necessarily conservative because predictive risk factors for exercise-triggered SCD have not been clearly identified, the risk is clearly not uniform across all athletes and all sports. The advent of implantable cardioverter defibrillators, automated external defibrillators, and successful implementation of emergency action plans may safely mitigate risk of sudden cardiac death during physical activity. An individualized approach to risk stratification of athletes that recognizes patient autonomy may allow many individuals with cardiomyopathies to safely train and compete.

The Bruce protocol has become the standard for exercise testing protocol in many exercise physiology laboratories, but is rarely a suitable test for athletes who often have complex hemodynamic and metabolic demands during exercise required for practice and competition. We describe the approach for exercise testing beyond the Bruce protocol and focus on strategies to individualize the testing protocol to the metabolic demands of an athlete's sport.

The recent advent of in-depth immune phenotyping projects in large-scale cohorts has allowed a first look into the factors that shape the inter-individual diversity of the human immune system. Genetic approaches have identified genetic diversity as drivers of 20-40% of the variation between the immune systems of individuals. The remaining 60-80% is shaped by intrinsic factors, with age being the predominant factor, as well as by environmental influences, where cohabitation and chronic viral infections were identified as key mediators. We review and integrate the recent in-depth large-scale studies on human immune diversity and its potential impact on health. VIDEO ABSTRACT. PMID- 27692232 TI - Outcome After Rewarming From Accidental Hypothermia by Use of Extracorporeal Circulation. AB - BACKGROUND: Accidental hypothermia with arrested circulation remains a condition associated with high mortality. In our institution, extracorporeal circulation (ECC) rewarming has been the cornerstone in treating such patients since 1987. We here explore characteristics and outcomes of this treatment, to identify significant merits and challenges from 3 decades of experience in ECC rewarming. METHODS: Sixty-nine patients rewarmed by ECC during the period from December 1987 to December 2015 were analyzed. One patient was excluded from the analyses because of combined traumatic cerebral injury. The analysis was focused on patient characteristics, treatment procedures, and outcomes were focused. Survivors were evaluated according to the cerebral performance categories scale. Simple statistics with nonparametric tests and chi2 tests were used. Median value and range are reported. RESULTS: Median age was 30 years (minimum 1.5, maximum 76), and the cause of accidental hypothermia was cold exposure (27.9%), avalanche (5.9%), and immersion/submersion accidents (66.2%). Eighteen patients survived (26.5%). The survival rate did not improve during the years. Survivors had lower serum potassium (p = 0.002), higher pH (p = 0.03), lower core temperature (p = 0.02), and shorter cardiopulmonary resuscitation time (p = 0.001), but ranges were wide. Although suspected primary hypoxia and hypothermia were associated with lower survival, we observed a 10.5% survival of these victims. Sixteen survivors had good outcome (cerebral performance category 1 or 2), whereas 2 patients with suspected primary hypoxia survived with severe cerebral disability (cerebral performance category 3). CONCLUSIONS: Despite extended experience with ECC rewarming, improved handling strategies, and intensive care, no overall improvement in survival was observed. Good outcome was observed even among patients with a dismal prognosis. PMID- 27692233 TI - Long-Term Outcome of Patients With Complete Atrioventricular Septal Defect Combined With the Tetralogy of Fallot: Staged Repair Is Not Inferior to Primary Repair. AB - BACKGROUND: Primary repair is the preferred strategy for surgical treatment of complete atrioventricular septal defect combined with the tetralogy of Fallot. However, a staged approach may be preferable for very small or cyanotic infants. The long-term outcomes of infants undergoing staged vs primary repair were compared. METHODS: Data from 47 patients with complete atrioventricular septal defect combined with the tetralogy of Fallot who were operated on at our institution between 1974 and 2013 were reviewed. The study end points were all cause death and reoperation. The patients were classified into two groups: staged repair (SR) and primary repair (PR). The indications for staged repair were cyanosis and young age. RESULTS: There were 22 SR and 25 PR patients. The SR patients were younger at the time of the initial operation (p = 0.001), and were more frequently cyanotic (21 SR vs 5 PR patients, p = 0.003). The 10-year survival after repair of the SR and PR patients was 78% +/- 11% and 83% +/- 8%, respectively (p = 0.8). No risk factors for death were identified. The 10-year freedom from reoperation for atrioventricular valve regurgitation of SR and PR patients after repair was 73% +/- 12% and 71% +/- 10%, respectively (p = 0.5). At least moderate atrioventricular valve regurgitation before repair was the only risk factor for reoperation (p = 0.01). CONCLUSIONS: Cyanotic and very young children with complete atrioventricular septal defect combined with the tetralogy of Fallot who require urgent treatment have long-term outcomes after staged repair similar to those of patients who undergo primary repair. Preoperative atrioventricular valve regurgitation is associated with increased risk for reoperation over the long-term. PMID- 27692235 TI - [Cutaneous loxoscelism, about an exceptional observation of 9 consecutive cases]. AB - INTRODUCTION: Loxosceles spiders are ubiquitous and responsible for many cases of envenomation in the world. The kind rufescens is present in the Provence and Occitan regions in France. During the summer 2015, we faced many Loxosceles rufescens cases of bites having led to extensive integumental necrosis whose features and singular evolution seems important to report. MATERIAL AND METHODS: We report the cases of nine patients who experienced a spider bite in the summer of 2015 in the Languedoc Roussillon. RESULTS: Of nine patients, eight patients had skin necrosis and five required surgical care. Five patients had a fever and had five other general signs such as important asthenia, joint pain, nausea and dizziness. CRP was very low normal in all patients. Finally, five of the nine patients reported a residual pain. DISCUSSION: L. rufescens is a small spider (7 to 15mm in diameter) having a cytotoxic venom. Loxoscelism diagnosis is usually made by removing a front necrotic skin lesion. Of systemic loxoscelism that have been described, some American species had fatal outcomes. The treatment remains controversial with various options: surgery, antibiotics, antihistaminics, antivenom. CONCLUSION: The diagnosis must be made in endemic areas when confronted to a necrosic integumentary infectious rapidly progressive, unresponsive to antibiotic treatment associated with atypical general signs. PMID- 27692234 TI - NADPH-diaphorase reactivity and Fos-immunoreactivity within the ventral horn of the lumbar spinal cord of cats submitted to acute muscle inflammation induced by injection of carrageenan. AB - The NADPH-diaphorase activity and Fos-immunoreactivity within the ventral horn of the lumbar spinal cord were studied in cats with acute unilateral myositis following injection of carrageenan into the m.m. gastrocnemius-soleus. In carrageenan-injected cats maximum in the mean number of intensely stained NADPH diaphorase reactive (NADPH-dr) neurons was found in lamina VII (+100%) and VIII (+33%) of the contralateral ventral horn of the L6/L7 segments as compared with control animals. The maximumal level of Fos-immunoreactivity was registered in the same laminae with ipsilateral predominance (39.3+/-4.6 and 7.6+/-0.9 cells), in comparison with the contralateral side (13.6+/-0.8 and 5.5+/-0.6 cells, respectively; P<0.05). We also visualized low-intensely stained and double labelled (Fos immunoreactive+low-intensely stained NADPH-dr) multipolar and fusiform Renshaw-like cells (RLCs) within the ventral horn on both sides of the L6/L7 segments in carrageenan-injected cats. We visualized the double labelled (Fos-ir+NADPH-dr) multipolar and fusiform Renshaw-like cells (RLCs) within the ventral horn on both sides of the L6/L7 segments in carrageenan-injected cats. A significant difference in the mean number of RLCs was recorded between the ipsi- and contralateral sides in the lamina VII (13.6+/-2.5 vs. 4.9+/-0.7 cells, respectively). We suppose that activation of inhibitory RLCs in ipsilateral lamina VII could be directed on attenuation of activation of motoneurons during muscle pain development. Our study showed that a significant contralateral increase in the number of NADPH-dr cells is accompanied by an ipsilateral increase in c-Fos expression in lamina VII. These data may suggest that NADPH-dr neurons of the contralateral ventral horn through commissural connections also involved in the maintenance of the neuronal activity associated with acute muscle inflammation. It is also hypothesized, that during acute myositis, plastic changes in the ventral horn activate the processes of disinhibition due to an increase in the number of NADPH-d-reactive neurons in the spinal gray matter.

AB - "Palsy of the upper limb" in children includes various diseases which leads to hypomobility of the member: cerebral palsy, arthrogryposis and obstetrical brachial plexus palsy. These pathologies which differ on brain damage or not, have the same consequences due to the early achievement: negligence, stiffness and deformities. Regular entire clinical examination of the member, an assessment of needs in daily life, knowledge of the social and family environment, are key points for management. In these pathologies, the rehabilitation is an emergency, which began at birth and intensively. Splints and physiotherapy are part of the treatment. Surgery may have a functional goal, hygienic or aesthetic in different situations. The main goals of surgery are to treat: joints stiffness, bones deformities, muscles contractures and spasticity, paresis, ligamentous laxity.

AB - BACKGROUND: Genetic factors predispose individuals to attention deficit/hyperactivity disorder (ADHD). Previous studies have reported linkage and association to ADHD of gene variants within ADGRL3. In this study, we functionally analyzed noncoding variants in this gene as likely pathological contributors. METHODS: In silico, in vitro, and in vivo approaches were used to identify and characterize evolutionary conserved elements within the ADGRL3 linkage region (~207 Kb). Family-based genetic analyses of 838 individuals (372 affected and 466 unaffected patients) identified ADHD-associated single nucleotide polymorphisms harbored in some of these conserved elements. Luciferase assays and zebrafish green fluorescent protein transgenesis tested conserved elements for transcriptional enhancer activity. Electromobility shift assays were used to verify transcription factor-binding disruption by ADHD risk alleles. RESULTS: An ultraconserved element was discovered (evolutionary conserved region 47) that functions as a transcriptional enhancer. A three-variant ADHD risk haplotype in evolutionary conserved region 47, formed by rs17226398, rs56038622, and rs2271338, reduced enhancer activity by 40% in neuroblastoma and astrocytoma cells (pBonferroni < .0001). This enhancer also drove green fluorescent protein expression in the zebrafish brain in a tissue-specific manner, sharing aspects of endogenous ADGRL3 expression. The rs2271338 risk allele disrupts binding of YY1 transcription factor, an important factor in the development and function of the central nervous system. Expression quantitative trait loci analysis of postmortem human brain tissues revealed an association between rs2271338 and reduced ADGRL3 expression in the thalamus. CONCLUSIONS: These results uncover the first functional evidence of common noncoding variants with potential implications for the pathology of ADHD. PMID- 27692241 TI - Automated activity monitoring and visual observation of estrus in a herd of loose housed Hereford cattle: Diagnostic accuracy and time to ovulation. AB - A prospective cohort study was performed in the purebred Hereford herd at Gotala Beef and Lamb Research Centre, Sweden. The study's first objective was to assess the ability of an automatic activity monitoring system (AAMS) to detect estrus in beef suckler cows, and its second objective was to estimate the time from estrus to ovulation. The study sample (n = 38) consisted of 14 Hereford heifers and 24 Hereford cows. Standardized visual observation of estrus was performed for 20 minutes thrice daily, and animal activity was recorded with an AAMS system, Heatime (SCR Engineers Ltd., Israel). Cows in estrus underwent transrectal ultrasonography every 8 hours, to estimate the time of ovulation. Blood samples for progesterone analysis were collected thrice weekly throughout the study period. A cutoff value of 1-ng progesterone/mL of serum was used to define luteal activity. The AAMS had a 90% (95% confidence interval [CI] 77%-97%) sensitivity and 100% specificity (95% CI 94%-100%), and visual detection of estrus had a 77% sensitivity (95% CI 62%-88%) and a 89% specificity (95% CI 79%-95%) for identifying estrus when compared to the gold standard defined by temporal pattern of serum progesterone concentration. When both methods were used in parallel, the sensitivity increased to 96% (95% CI 86%-99%), and the specificity increased to 90% (95% CI 80%-96%). The time of ovulation after estrus was determined on 50 occasions. The median estrus (AAMS detected) to ovulation interval was 25 hours for heifers and 23 hours for cows (interquartile range 11-29 hours and 19-25 hours, respectively). The median estrus (visually detected) to ovulation interval was 28 hours for heifers and 21 hours for cows (interquartile range 13-29 hours for both categories). In conclusion, the AAMS had both a higher sensitivity and specificity for estrus detection than thrice-daily visual observation. The time from detection of estrus to ovulation observed in this study indicates that reproductive performance might be improved if Hereford cattle are inseminated sooner after detection of estrus than is currently recommended. PMID- 27692238 TI - Heterogeneity in Dopamine Neuron Synaptic Actions Across the Striatum and Its Relevance for Schizophrenia. AB - Brain imaging has revealed alterations in dopamine uptake, release, and receptor levels in patients with schizophrenia that have been resolved on the scale of striatal subregions. However, the underlying synaptic mechanisms are on a finer scale. Dopamine neuron synaptic actions vary across the striatum, involving variations not only in dopamine release but also in dopamine neuron connectivity, cotransmission, modulation, and activity. Optogenetic studies have revealed that dopamine neurons release dopamine in a synaptic signal mode, and that the neurons also release glutamate and gamma-aminobutyric acid as cotransmitters, with striking regional variation. Fast glutamate and gamma-aminobutyric acid cotransmission convey discrete patterns of dopamine neuron activity to striatal neurons. Glutamate may function not only in a signaling role at a subset of dopamine neuron synapses, but also in mediating vesicular synergy, contributing to regional differences in loading of dopamine into synaptic vesicles. Regional differences in dopamine neuron signaling are likely to be differentially involved in the schizophrenia disease process and likely determine the subregional specificity of the action of psychostimulants that exacerbate the disorder, and antipsychotics that ameliorate the disorder. Elucidating dopamine neuron synaptic signaling offers the potential for achieving greater pharmacological specificity through intersectional pharmacological actions targeting subsets of dopamine neuron synapses.

AB - The mantra that dietary (saturated) fat must be minimized to reduce cardiovascular disease (CVD) risk has dominated nutritional guidelines for decades. Parallel to decreasing intakes of fat and saturated fatty acids (SFA), there have been increases in carbohydrate and sugar intakes, overweight, obesity and type 2 diabetes mellitus. The "lipid hypothesis" coined the concept that fat, especially SFA, raises blood low-density lipoprotein-cholesterol and thereby CVD risk. In view of current controversies regarding their adequate intakes and effects, this review aims to summarize research regarding this heterogenic group of fatty acids and the mechanisms relating them to (chronic) systemic low-grade inflammation, insulin resistance, metabolic syndrome and notably CVD. The intimate relationship between inflammation and metabolism, including glucose, fat and cholesterol metabolism, revealed that the dyslipidemia in Western societies, notably increased triglycerides, "small dense" low-density lipoprotein and "dysfunctional" high-density lipoprotein, is influenced by many unfavorable lifestyle factors. Dietary SFA is only one of these, not necessarily the most important, in healthy, insulin-sensitive people. The environment provides us not only with many other proinflammatory stimuli than SFA but also with many antiinflammatory counterparts. Resolution of the conflict between our self designed environment and ancient genome may rather rely on returning to the proinflammatory/antiinflammatory balance of the Paleolithic era in consonance with the 21st century culture. Accordingly, dietary guidelines might reconsider recommendations for SFA replacement and investigate diet in a broader context, together with nondietary lifestyle factors. This should be a clear priority, opposed to the reductionist approach of studying the effects of single nutrients, such as SFA.

PMID- 27692245 TI - Is Bladder Training by Clamping Before Removal Necessary for Short-Term Indwelling Urinary Catheter Inpatient? A Systematic Review and Meta-analysis. AB - PURPOSE: Urinary catheterization is a common technique in clinical practice. There is, however, no consensus on management prior to removal of the indwelling catheter for short-term patients. This systematic review examined the necessity of clamping before removal of an indwelling urinary catheter in short-term patients. METHODS: A systematic literature review was conducted using eight databases and predetermined keywords-guided searches. Some 2,515 studies were evaluated. Ten studies that met the inclusion criteria were selected. RESULTS: The quality of the studies was assessed using the Jadad scoring system. Only 40.0% of studies were rated as high quality. This review found that catheter clamping prior to removal was not necessary for the short-term patient. When made a comparison with the unclamping group, there was no significant difference in recatheterization risk, risk of urine retention, patients' subjective perceptions and rate of urinary tract infection. CONCLUSIONS: This review indicated that bladder training by clamping prior to removal of urinary catheters is not necessary in short-term catheter patients. In addition, clamping carries the risk of complications such as prolonging urinary catheter retention and urinary tract injury. Further investigation requires higher quality methodologies and more diverse study designs. PMID- 27692246 TI - Structural Equation Modeling to Assess Discrimination, Stress, Social Support, and Depression among the Elderly Women in South Korea. AB - PURPOSE: The purpose of this study was to find the relationship and conceptual model of discrimination, stress, support, and depression among the elderly in South Korea. METHODS: This was a cross-sectional descriptive study involving 207 community-dwelling elders. Data were collected through questionnaires from May 5 to May 31, 2014 in community senior centers, and analyzed using descriptive statistics, t test, analysis of variance, Scheffe test, and structural equation modeling. RESULTS: There were significant effects of discrimination on stress, support on stress and stress on depression. Moreover, there were two significant indirect effects observed between discrimination and depression, and between support and depression. For each indirect effect, the mediating factor was stress. Additionally, there was no direct effect between discrimination and depression or support. CONCLUSIONS: This study found that social support and discrimination had indirect effects on depression through stress. More specifically, decreased stress led to a reduction of depression. Therefore, social support based on a thorough understanding of stress is very important for caring elderly who are depressive. PMID- 27692247 TI - Influencing Factors of Intention to Receive Pap Tests in Vietnamese Women who Immigrated to Taiwan for Marriage. AB - PURPOSE: This study aimed to explore the factors associated with the intention to receive a Pap test among married immigrant women of Vietnamese origin living in Taiwan. METHODS: This was a cross-sectional community-based study. We enrolled 281 women aged 30 years and over in the study, from July 2013 to January 2014. The participants' characteristics, cervical cancer knowledge, Pap test knowledge, attitudes toward cervical cancer, barriers to receiving a Pap test, fatalism, and intention to receive a Pap test, were measured using self-report questionnaires. Hierarchical multiple regression analyses were performed to examine the variables associated with participants' intentions to receive a Pap test. RESULTS: Vietnamese women with low scores on the measures of cervical cancer knowledge and perceived barriers to receiving a Pap test were more willing to receive the test, as were those with high scores on the measures of Pap test knowledge and fatalism. Women who received a Pap test in the previous year were more willing to receive a Pap test within the next 3 years. CONCLUSIONS: Preventive healthcare for immigrant women should be a focus of nurses. The development of culturally appropriate health education and strategies should enhance their knowledge of Pap tests and reduce perceived barriers to Pap test participation. This study's results can be a reference for nurses who work with immigrant women. PMID- 27692248 TI - Psychometric Evaluation of a Turkish Version of the Diabetes Fear of Self injecting and Self-testing Questionnaire (D-FISQ). AB - PURPOSE: To examine the psychometric properties of a Turkish version of the Diabetes Fear of Injecting and Self-testing Questionnaire (D-FISQ). METHODS: Forward-backward translation of the D-FISQ from English into Turkish was conducted. Original English and translated forms were examined by a panel group. Validity was investigated using content, confirmatory factor analysis, and divergent validity. Reliability was assessed using Cronbach alpha values, item total correlations, and intraclass correlations. The sample comprised 350 patients with diabetes. Data were analyzed using SPSS 15.0 for Windows and LISREL 8. RESULTS: The content validity index for the panel members was .90, which indicated perfect content validity; items in D-FISQ were clear, concise, readable, and distinct. Confirmatory factor analysis confirmed the original construct of the D-FISQ. All items had factor loadings higher than the recommended level of .40. The D-FISQ scores were discriminated by the level of anxiety. Reliability results were also satisfactory. Cronbach alpha values were within ideal limits. Item-total correlation coefficient ranged from .72 to .86. In terms of test-retest reliability, intraclass correlation coefficient was found to be over .90. CONCLUSIONS: D-FISQ is a valid and reliable questionnaire in assessing needle-prick fear among Turkish patients with diabetes. We recommend performing the Turkish D-FISQ in determining and screening patients with diabetes who have fear related to self-insulin injection and finger-prick test. Thus, health care professionals should be aware of the potential consequences of injection fear such as insulin misuse and poor self-monitoring of blood glucose, which may have unfavorable effects on optimal diabetes management. PMID- 27692249 TI - Other Side of Breast Cancer: Factors Associated with Caregiver Burden. AB - PURPOSE: This study aimed to determine factors associated with caregiver burden among primary caregivers of women with breast cancer in Iran. METHODS: This was a descriptive correlation study conducted in 2012 on 150 main caregivers of patients with breast cancer who came to the oncology clinic of Shahid Ghazi hospital in Tabriz, Iran. A questionnaire which included caregiving-related factors and the Zarit Burden Interview was used for data collection after its validity and reliability were determined. Data was analyzed using SPSS 13.0 software with descriptive and analytic statistics. The association between significant variables and the dependent variable with an observation of the effects of other variables was assessed using the multiple linear regression model. RESULTS: The mean age of caregivers was 39.60 +/- 13.80 years old, and 77 (51.3%) of them were men. The mean score of the Zarit Burden Interview was 30.55 +/- 19.18. In the regression model, the mean score of activities of daily living, level of education, gender, and financial status were identified as the determining factors of the burden of caregivers. CONCLUSIONS: Primary caregivers need to be financially supported by the relevant organizations. Care skills training and providing palliative care seem helpful in reducing the pain and the burden of family caregivers for patients with breast cancer. PMID- 27692250 TI - Psychometric Properties of Korean Version of Self-Efficacy of Evidence-Based Practice Scale. AB - PURPOSE: This study is to evaluate the psychometric properties of the Korean version of the Self-Efficacy of Evidence-Based Practice (SE-EBP) scale, which was originally developed by Chang and Crowe. The beta-version of the SE-EBP is a modified version of the original SE-EBP, which measures the clinical nurses' confidence in finding, appraising, and implementing evidence into practice. Although the original SE-EBP has been validated, no study has been conducted to validate the Korean version of SE-EBP. METHODS: The original scale was translated into Korean through a process of forward and back translation of the original scale. After getting confirmation of the equivalence of the Korean forward translation by the original author, exploratory factor analysis and confirmatory factor analysis of data from 212 clinical nurses were used to test construct validity. Internal consistency was examined using Cronbach alpha coefficients. For the statistical analysis, STATA version 13.0 software program was used. RESULTS: Exploratory factor analysis of the 28 items revealed three factors with eigenvalues above 1, accounting for 60.2% of the total variance. Confirmatory factor analysis showed good fit of the three-factor structure which was statistically significant (chi2=718.61, df=330, p<.01). For internal consistency, Cronbach alpha coefficient for the total scale was .95, and it was greater than .80 for each of the three subscales. CONCLUSIONS: The Korean version of SE-EBP scale showed evidence of adequate construct validity and reliability. This study might have contributed to a wider application of the SE-EBP scale, but further studies are needed to provide more evidence on the structure of the scale. PMID- 27692251 TI - A Predictive Model of Domestic Violence in Multicultural Families Focusing on Perpetrator. AB - PURPOSE: This study was conducted to assess predictor variables of husbands in multicultural families and examine the relationship among variables after setting up a hypothetical model including influencing factors, so as to provide a framework necessary for developing nursing interventions of domestic violence. METHODS: The participants were 260 husbands in multicultural families in four cities in Korea. Data were analyzed using SPSS 22.0 and AMOS 20.0. RESULTS: Self control, social support, family of origin violence experience and stress on cultural adaptation directly affected to dysfunctional communication, and the explanatory power of the variables was 64.7%. Family of origin violence experience in domestic stress on cultural adaptation, and dysfunctional communication were directly related to domestic violence in multicultural families, and the explanatory power of the variables was 64.6%. We found out that all variables in the model had mediation effects to domestic violence through dysfunctional communication. In other words, self-control and social support had complete mediation effects, and family of origin violence experience in domestic violence and stress on cultural adaptation had partial mediation effects. CONCLUSIONS: The variables explained in this study should be considered as predictive factors of domestic violence in multicultural families, and used to provide preventive nursing intervention. Our resutls can be taken into account for developing and implementing programs on alleviating dysfunctional communication in multicultural families in Korea. PMID- 27692252 TI - Why Women Living in an Obstetric Care Underserved Area Do Not Utilize Their Local Hospital Supported by Korean Government for Childbirth. AB - PURPOSE: This study aimed to understand why mothers do not utilize the prenatal care and delivery services at their local hospital supported by the government program, the Supporting Program for Obstetric Care Underserved Area (SPOU). METHODS: We conducted a focus group interview by recruiting four mothers who delivered in the hospital in their community (a rural underserved obstetric care area) and another four mothers who delivered in the hospital outside of the community. RESULTS: From the finding, the mothers were not satisfied with the quality of services that the community hospital provided, in terms of professionalism of the obstetric care team, and the outdated medical device and facilities. Also, the mothers believed that the hospital in the metropolitan city is better for their health as well as that of their babies. The mothers who delivered in the outside community hospital considered geographical closeness less than they did the quality of obstetric care. The mothers who delivered in the community hospital gave the reason why they chose the hospital, which was convenience and emergency preparedness due to its geographical closeness. However, they were not satisfied with the quality of services provided by the community hospital like the other mothers who delivered in the hospital outside of the community. CONCLUSIONS: Therefore, in order to successfully deliver the SPOU program, the Korean government should make an effort in increasing the quality of maternity service provided in the community hospital and improving the physical factors of a community hospital such as outdated medical equipment and facilities. PMID- 27692253 TI - Role of Emotional Intelligence in Conflict Management Strategies of Nurses. AB - PURPOSE: This study analyzes the emotional intelligence levels and conflict management strategies of nurses and the association between them. METHODS: This cross-sectional, descriptive study was conducted with 277 nurses in a stratified random sample from a university hospital in Turkey. The data were collected from nurses who gave their informed consent to participate using a personal information form, the Rahim Organizational Conflict Inventory-II and Bar-On's Emotional Quotient Inventory (EQ-I). Data were assessed by descriptive statistics, t tests, and Pearson correlation analyses, using SPSS software. RESULTS: The levels of the nurses' strategies were as follows: avoiding (M = 2.98), dominating (M = 2.76), and obliging (M = 2.71) were medium; compromising (M = 1.99) and integration (M = 1.96) were low. The levels of the emotional intelligence of nurses (mean = 2.75) were medium on a 5-point scale. Integration (r = .168), obliging (r = .25), dominating (r = .18), and compromising (r = .33), which are conflict management strategies, were positively correlated with scores of emotional intelligence, and avoiding (r = -.25) was negatively correlated with scores of emotional intelligence (p < .05). CONCLUSIONS: The study determined that nurses' emotional intelligence affects conflict management strategies. To use effective strategies in conflict management, nurses must develop emotional intelligence. Training programs on conflict management and emotional intelligence are needed to improve effective conflict management in healthcare facilities. PMID- 27692254 TI - Relationship between Organizational Culture and Workplace Bullying among Korean Nurses. AB - PURPOSE: To identify the relationship between organizational culture and experience of workplace bullying among Korean nurses. METHODS: Participants were 298 hospital nurses in Busan, South Korea. We assessed nursing organizational culture and workplace bullying among nurses using structured questionnaires from July 1 through August 15, 2014. RESULTS: Most participants considered their organizational culture as hierarchy-oriented (45.5%), followed by relation oriented (36.0%), innovation-oriented (10.4%), and task-oriented (8.1%). According to the operational bullying criteria, the prevalence of workplace bullying was 15.8%. A multivariate logistic regression analysis revealed that the odds of being a victim of bullying were 2.58 times as high among nurses in a hierarchy-oriented culture as among nurses in a relation-oriented culture [95% confidence interval (1.12, 5.94)]. CONCLUSIONS: The results suggest that the types of nursing organizational culture are related to workplace bullying in Korean nurses. Further research is needed to develop interventions that can foster relation-oriented cultures to prevent workplace bullying in nurses. PMID- 27692255 TI - Validation of Sinhala Version of Cardiff Wound Impact Schedule in Patients with Diabetic Leg and Foot Ulcers. AB - PURPOSE: To validate the Cardiff Wound Impact Schedule (CWIS) to assess the health-related quality of life (HRQoL) of Sri Lankan patients with diabetic leg and foot ulcers. METHODS: English version of CWIS was examined for cultural compatibility, translated into Sinhala and pretested. The Sinhala version was administered in parallel with the validated Sinhala version of SF-36 by an interviewer to all patients (n = 140) at baseline to determine the construct validity. Reliability of CWIS was measured by internal consistency and test retest stability. The instrument was readministered in 2 weeks on 33 patients with nonhealing ulcers to determine the test-retest stability and in 3 months on 50 patients with healed ulcers to determine the ability of CWIS to discriminate HRQoL between patients with healed versus nonhealed ulcers. Acceptability of CWIS was assessed by the response rate, completion rate and the average time taken to complete a single interview. RESULTS: The construct validity demonstrated moderately significant correlations between related subscales of CWIS and SF-36 (Spearman's r = .32-.51, p = .021 to p < .001) for the whole study sample. Internal consistencies (Cronbach alpha = .68-.86) and test-retest stability (.56 .70) were acceptable. The tool was sensitive in discriminating the impact of the wound on HRQoL in healed versus nonhealed status (p <= .001). The tool showed good acceptability. CONCLUSIONS: The Sinhala version of CWIS is valid, reliable and acceptable for assessing the impact of wound on HRQoL. This instrument is sensitive in detecting the differences of the impact of healed and nonhealed ulcers on QoL in patients with diabetic leg and foot ulcer. PMID- 27692256 TI - Analysis of Workplace Health Education Performed by Occupational Health Managers in Korea. AB - PURPOSE: To evaluate workplace health education as practiced by occupational health managers based on standardized job tasks and suggest priority tasks and areas to be trained. METHODS: The study was conducted between November 10, 2013 and April 30, 2014. The tool used in this study was standardized job tasks of workplace health education for occupational health managers which was developed through methodological steps. It was evaluated by 233 worksite occupational health managers. Data were analyzed using SPSS 21.0. RESULTS: Predicting variables of workplace health education performance were the "analysis and planning" factor, type of enterprise, and form of management. Healthcare professionals and occupational health managers who managed the nonmanufacturing industry showed high importance and low performance level in "analysis and planning" factor. CONCLUSIONS: "Analysis and planning" skill is priority training area for healthcare professionals and occupational health managers who managed nonmanufacturing industry. It is necessary to develop a training curriculum for occupational health managers that include improving analysis of worksites and plans for a health education program.

AB - Data science uses computer science and statistics to extract new knowledge from high-dimensional datasets (ie, those with many different variables and data types). Mental health research, diagnosis, and treatment could benefit from data science that uses cohort studies, genomics, and routine health-care and administrative data. The UK is well placed to trial these approaches through robust NHS-linked data science projects, such as the UK Biobank, Generation Scotland, and the Clinical Record Interactive Search (CRIS) programme. Data science has great potential as a low-cost, high-return catalyst for improved mental health recognition, understanding, support, and outcomes. Lessons learnt from such studies could have global implications. PMID- 27692270 TI - Increased severity of sleep-disordered breathing is associated with insomnia and excessive somnolence in primary school children. AB - OBJECTIVE: The aim of the study was to investigate the prevalence of difficulty with initiation or maintenance of sleep (DIMS) and excessive daytime sleepiness (EDS) in a general pediatric population, and to evaluate the relationship between these conditions and sleep-disordered breathing (SDB) symptom intensity. METHODS: This population-based cross-sectional study from 27 primary schools in a medium sized city in Poland was based on use of a questionnaire regarding demographic data, symptoms of SDB, DIMS, and EDS. Data were collected between September and December 2014. In all, 2940 caregivers were recruited and were asked to fill-out questionnaires and written consent. RESULTS: A total of 68% of the questionnaires (n = 1987) were returned and analyzed. Habitual snoring (HS) was reported in 104 (5.3%) children. DIMS and EDS were seen in 137 children (6.9%) and 117 children (5.9%), respectively. The prevalence of DIMS increased from 3.5% in children who never snored to 28.6% in children who snored very often or always. Similarly, the prevalence of EDS was 2.7% in children who did not snore and increased to 19% in children who snored very often or always. No correlation was seen between increasing DIMS (r = 0.006, p > 0.05) or EDS (r = -0.031, p > 0.05) scores and body mass index. CONCLUSIONS: This study is the first to measure the symptoms of both DIMS and EDS in a general pediatric population and to assess the relationship between both DIMS and EDS and SDB in children. We found that children with more frequent snoring had a higher prevalence of DIMS as well as EDS; however, there was no correlation between body mass index and either DIMS or EDS symptom severity. PMID- 27692271 TI - Daytime napping and increased risk of incident respiratory diseases: symptom, marker, or risk factor? AB - BACKGROUND: We have identified a strong association between daytime napping and increased mortality risk from respiratory diseases, but little is known about the relationship between daytime napping and respiratory morbidity. METHODS: Data were drawn from the European Prospective Investigation into Cancer and Nutrition Norfolk cohort. Participants reported napping habits during 1998-2000 and were followed up for respiratory disease hospital admissions until March 2009. Cox proportional hazards regression was used to examine the association between daytime napping and respiratory disease incidence risk. RESULTS: The study sample included 10,978 men and women with a mean age of 61.9 years, and a total of 946 incident respiratory disease cases were recorded. After adjustment for age, sex, social class, education, marital status, employment status, nightshift work, body mass index, physical activity, smoking, alcohol intake, self-reported general health, hypnotic drug use, habitual sleep duration, and preexisting health conditions, daytime napping was associated with an increase in the overall respiratory disease incidence risk (hazard ratio (HR) = 1.32, 95% confidence interval (CI) 1.15, 1.52 for napping <1 h; HR = 1.54, 95% CI 1.14, 2.09 for napping >=1 h). This association was more pronounced for lower respiratory diseases, especially for the risk of chronic lower respiratory diseases (HR = 1.52, 95% CI: 1.18, 1.96 for napping <1 h; HR = 1.72, 95% CI: 1.01, 2.92 for napping >=1 h, overall p = 0.003). CONCLUSIONS: Excessive daytime napping might be a useful marker of future respiratory disease incidence risk. Further studies are required to confirm these findings and help understand potential mechanisms. PMID- 27692272 TI - Hyperarousal in insomnia and hypnotic dose escalation. AB - BACKGROUND: Given concerns about the abuse liability of hypnotics, this study assessed hyperarousal in people with insomnia and its relation to hypnotic self administration over 12 months of nightly hypnotic use. METHODS: Ninety-five subjects with insomnia (age 32-64 years) underwent screening nocturnal polysomnogram (NPSG) and Multiple Sleep Latency Test (MSLT) the following day and, then, were randomized to receive zolpidem 10 mg or placebo nightly for 12 months. NPSGs and MSLTs were conducted and urine was collected (0700-1500 h) and analyzed for norepinephrine (NE) levels during months one and eight on study medication. A subset (n = 54) underwent hypnotic self-administration assessments in months one, four, and 12. RESULTS: Mean daily sleep latency on screening MSLT was distributed across the full range of MSLT latencies (2-20 min). The highest screening MSLT latencies were detected in subjects with higher NE levels, compared to those with the lowest MSLT latencies. In the subset undergoing self administration assessment, those with the highest MSLT latencies chose more capsules (placebo and zolpidem) and increased the number of capsules chosen in months four relative to month one, compared to those with the lowest MSLT latencies. CONCLUSIONS: These data show that some insomniacs are hyperaroused with high MSLT/NE levels and, compared to low MSLT/NE insomniacs, they increase the number of capsules (zolpidem and placebo) self-administered on months four and 12 relative to Month one. PMID- 27692273 TI - Abnormal thyroid hormones and non-thyroidal illness syndrome in obstructive sleep apnea, and effects of CPAP treatment. AB - OBJECTIVE: In obstructive sleep apnea (OSA), while both hypothyroidism and hyperthyroidism have been studied, the occurrence of non-thyroidal illness syndrome (NTIS) (normal thyroid stimulating hormone [TSH] with low triiodotironine) has not been investigated. We explored the occurrence of NTIS in patients with moderate to severe OSA and its relationship to the severity of nocturnal respiratory disorders. We also studied the occurrence of subclinical hypothyroidism (SH, ie, high TSH with normal thyroxine) in OSA and changes in circulating TSH, free triiodotironine (fT3) and free thyroxine (fT4) after CPAP treatment. METHODS: After a nocturnal respiratory polysomnography, 125 consecutive patients with moderate to severe OSA and 60 control subjects with normal nocturnal respiration were recruited. Morning circulating TSH, fT3, and fT4 were measured in all subjects. In a subsample of patients, nocturnal polysomnography and hormonal determinations were repeated after CPAP treatment for five months. RESULTS: NTIS was found in 13 (10.4%), and SH in ten (8%) OSA subjects, but not in any control subjects. Patients with NTIS showed worse mean nocturnal oxygen saturation and time with saturation <90% (both p < 0.001). After treatment, NTIS subjects (n = 13) showed an increase in fT3 (p < 0.001) to the normal range, and SH subjects (n = 6) a slight decrease in TSH (p = 0.01). In the patients with normal hormones before treatment (n = 45), no change was observed. CONCLUSIONS: NTIS may occur in OSA patients with severe nocturnal hypoxemia. OSA treatment is followed by an improvement in TSH in patients with abnormal baseline levels of this hormone, and by recovery of NTIS. PMID- 27692274 TI - Sleep characteristics in type 1 diabetes and associations with glycemic control: systematic review and meta-analysis. AB - OBJECTIVES: The association between inadequate sleep and type 2 diabetes has garnered much attention, but little is known about sleep and type 1 diabetes (T1D). Our objectives were to conduct a systematic review and meta-analysis comparing sleep in persons with and without T1D, and to explore relationships between sleep and glycemic control in T1D. METHODS: Studies were identified from Medline and Scopus. Studies reporting measures of sleep in T1D patients and controls, and/or associations between sleep and glycemic control, were selected. RESULTS: A total of 22 studies were eligible for the meta-analysis. Children with T1D had shorter sleep duration (mean difference [MD] = -26.4 minutes; 95% confidence interval [CI] = -35.4, -17.7) than controls. Adults with T1D reported poorer sleep quality (MD in standardized sleep quality score = 0.51; 95% CI = 0.33, 0.70), with higher scores reflecting worse sleep quality) than controls, but there was no difference in self-reported sleep duration. Adults with TID who reported sleeping >6 hours had lower hemoglobin A1c (HbA1c) levels than those sleeping <=6 hours (MD = -0.24%; 95% CI = -0.47, -0.02), and participants reporting good sleep quality had lower HbA1c than those with poor sleep quality (MD = -0.19%; 95% CI = -0.30, -0.08). The estimated prevalence of obstructive sleep apnea (OSA) in adults with TID was 51.9% (95% CI = 31.2, 72.6). Patients with moderate-to-severe OSA had a trend toward higher HbA1c (MD = 0.39%, 95% CI = -0.08, 0.87). CONCLUSION: T1D was associated with poorer sleep and high prevalence of OSA. Poor sleep quality, shorter sleep duration, and OSA were associated with suboptimal glycemic control in T1D patients.

PMID- 27692276 TI - Emotional availability at bedtime, infant temperament, and infant sleep development from one to six months. AB - Infant sleep consolidates rapidly during the first half year of life in the context of a dynamic, bidirectional exchange between infant characteristics and the caregiving environment. The current study examined the relationship between mothers' emotional availability (EA) at bedtime and infant temperament, and objectively assessing infant sleep development from one to six months, particularly focus on whether infant temperament moderated linkages between EA at bedtime and infant sleep development. The sample consisted of 72 mother-infant dyads, and the measures included actigraphy-assessed infant sleep at one and six months, observed maternal EA coded from bedtime videos at 3 and 6 months, and maternal reports of infant temperament at three and six months. The analysis showed significant positive effects of maternal EA at bedtime on developmental changes in infant sleep minutes. Additionally, infant temperamental surgency moderated the influence of EA at bedtime on the increase in infant sleep minutes. In other words, highly surgent infants whose mothers were emotionally available at bedtime showed a greater increase in their sleep time than other infants. The results are discussed in terms of the transactional model of infant sleep development. PMID- 27692277 TI - Sleep and melatonin secretion abnormalities in children and adolescents with fetal alcohol spectrum disorders. AB - OBJECTIVES: Caregivers describe significant sleep disturbances in the vast majority of children and adolescents, which is diagnosed as fetal alcohol spectrum disorders (FASD), but objective data on sleep disorders in this population are almost completely lacking. Animal models suggest that intrauterine alcohol exposure may disrupt sleep wake patterns, cause sleep fragmentation, and specifically affect the suprachiasmatic nucleus, thus disrupting melatonin secretion. The objective of this pioneering study was to evaluate sleep and melatonin abnormalities in children with FASD using objective, gold-standard measures. METHODS: Children and adolescents (N = 36, 6-18 years) with FASD participated in clinical assessments by sleep specialists, overnight polysomnography (PSG), and a dim light melatonin onset (DLMO) test in a pediatric sleep laboratory. PSG was analyzed according to standardized scoring guidelines and sleep architecture was compared with normative data. DLMOs were determined and melatonin secretion curves were evaluated qualitatively to classify melatonin profiles. Sleep disorders were evaluated according to international diagnostic criteria. RESULTS: There was a high prevalence (58%) of sleep disorders. The most common sleep problems were parasomnias (27.9%) and insomnia (16.8%). The sleep studies showed lower than normal sleep efficiency and high rates of sleep fragmentation. Most participants (79%) had an abnormal melatonin profile. CONCLUSIONS: This study led to the recognition that both sleep and melatonin secretion abnormalities are present in children with FASD. Therefore, to be effective in managing the sleep problems in children with FASD, one needs to consider both the sleep per se and a possible malfunction of the circadian regulation. PMID- 27692278 TI - Default mode network disturbances in restless legs syndrome/Willis-Ekbom disease. AB - BACKGROUND: The unusual sensations of restless legs syndrome/Willis-Ekbom disease (RLS/WED) are induced by rest or a low arousal state with a circadian variation in the threshold for induction. It has been suggested that the emergence of RLS/WED symptoms relates to abnormal brain functions dealing with internally generated stimuli. The purpose of this study was to investigate the changes in the default mode network (DMN) in RLS/WED subjects. METHODS: Sixteen drug-naive, idiopathic, RLS/WED subjects, and 16 age-matched and gender-matched healthy subjects were scanned in an asymptomatic resting state. A comparison of the DMN was conducted between the two groups. Resting state functional magnetic resonance imaging (MRI), Korean versions of the International RLS scale, and other sleep questionnaires were used. RESULTS: The results showed reductions in the DMN connectivity in the left posterior cingulate cortex, the right orbito-frontal gyrus, the left precuneus, and the right subcallosal gyrus of the RLS/WED subjects. The DMN connectivity was increased in sensory-motor-associated circuits, which included the right superior parietal lobule, the right supplementary motor area, and the left thalamus. In addition, the connectivity between the DMN and thalamus was negatively correlated with that in the orbito frontal gyrus and the subcallosal gyrus in the subjects. CONCLUSIONS: The results showed disturbances of the DMN in RLS/WED subjects that influence the thalamic relay sensory-motor-associated circuit. These findings may underscore the fact that RLS/WED subjects have disturbances in default mode network functions involving internal stimuli in the resting state. This may be related to compensatory changes to maintain resting. PMID- 27692279 TI - Factors predisposing to worsening of sleep apnea in response to fluid overload in men. AB - OBJECTIVES: Obstructive sleep apnea (OSA) is highly prevalent in patients with fluid-retaining conditions. Using bioimpedance measurements, previous studies have shown that the greater the amount of fluid redistributed from the legs to the neck overnight, the greater the severity of OSA. Our objective was to investigate factors that predispose the development or worsening of OSA in response to experimental fluid overload. METHODS: Fifteen normotensive and non obese adult men with and without OSA underwent polysomnography (PSG) during which normal saline was infused intravenously at a minimal rate to keep the vein open (control) or as a bolus of 22 ml/kg body weight (approximately 2 L) in a random order and crossed over after a week. RESULTS AND CONCLUSIONS: Before and after sleep, neck circumference and bioimpedance were measured to calculate neck resistance, reactance, phase angle, and fluid volume. Subjects who experienced more than a twofold increase in apnea-hypopnea index (AHI) or obstructive AHI from control to intervention and had an AHI>10 during intervention were considered susceptible to the development or worsening of OSA. Baseline neck circumference and phase angle before saline infusion were independently associated with increased susceptibility to developing or worsening OSA in response to saline infusion. In non-obese men, a larger neck circumference and bioimpedance phase angle of the neck, which may be associated with larger pharyngeal tissue content, is associated with increased susceptibility for worsening of OSA in response to fluid overloading. PMID- 27692281 TI - Correlates of self-reported weekday sleep duration in adolescents: the 18-year follow-up of the 1993 Pelotas (Brazil) Birth Cohort Study. AB - OBJECTIVE: To investigate factors associated with sleep duration in adolescence. METHODS: Data are from the 1993 Pelotas Birth Cohort Study of 5249 live births. Of these individuals, 4563 were located for follow-up at 18 years of age, and 4106 agreed to be interviewed (follow-up rate 81.3%). Sleep duration was continuously assessed by survey as hours per weekday. Additional covariates were collected during the perinatal period and at the 11- and 18-year follow-ups. Linear regression models were used to estimate associations between sleep duration and its hypothesized influences. All analyses were sex-stratified. RESULTS: The average sleep duration among participants was 8.4 hours (standard deviation 1.9). Longer sleep duration at 18 years of age was associated with the following perinatal factors: low maternal schooling, low family income, maternal black skin color, and low birth weight; and with the following factors measured at 18 years of age: being out of school, low achieved schooling, low family income, absence of depressive symptoms, and high screen time. CONCLUSION: Social and demographic variables may play an important role in determining adolescents' sleep duration, but the nature of these relationships in Brazil may differ from those observed in higher-income contexts. PMID- 27692280 TI - Association of urinary melatonin levels and aging-related outcomes in older men. AB - BACKGROUND: Circadian disruptions can contribute to accelerated aging, and the circadian system regulates cognitive and physical functions; therefore, circadian markers (eg, melatonin) may be associated with key aspects of healthy aging and longevity. OBJECTIVE: To evaluate urinary melatonin levels in relation to cognitive function, physical function, and mortality among 2,821 older men in the Osteoporotic Fractures in Men Study DESIGN: Cohort study. MEASUREMENTS: In 2003 2005, participants provided first-morning spot urine samples, which were assayed for 6-sulfatoxymelatonin (the primary melatonin metabolite in urine); cognitive and physical function assessments were completed twice, at baseline and an average of 6.5 years later. Participant deaths were confirmed by central review of death certificates over a mean of 9.2 years of follow up. RESULTS: In multivariable-adjusted regression models, we observed a significant trend of better Digit Vigilance Test scores (ie, decreased time to completion) at baseline across increasing melatonin quartiles (p-trend = 0.01); however, mean time-to completion scores did not significantly differ comparing extreme quartiles (group means: 547.1 seconds (95% CI: 533.6, 560.6) versus 561.3 seconds (95% CI: 547.8, 574.9)), and there were no associations of urinary melatonin levels with other cognitive test scores, or any cognitive change scores over time. Furthermore, melatonin levels were not related to physical function scores (p-trends = 0.4 for walking speed, 0.7 for chair stands, and 0.6 for grip strength in fully-adjusted models) or mortality risk (p-trend = 0.3 in the fully-adjusted model). CONCLUSION: We found little evidence of associations between urinary melatonin levels and key measures of healthy aging and mortality in this cohort of older men. Further research should explore the relation of melatonin, particularly if assessed earlier in life, and other circadian markers with healthy aging outcomes. PMID- 27692282 TI - The effect of second-generation antipsychotic drugs on sleep parameters in patients with unipolar or bipolar disorder. AB - Sleep disturbances predominantly take the form of insomnia in patients with unipolar disorder, while patients with bipolar disorder show a decreased need for sleep. Sleep impairment in these patients is a risk factor for the development of a major depressive episode and suicidal behavior. Administration of second generation antipsychotics (SGAs) olanzapine, quetiapine, and ziprasidone as augmentation therapy or monotherapy to unipolar and bipolar disorder patients, respectively, has been shown to improve sleep continuity and sleep architecture. Thus, their use by these patients could ameliorate their sleep disorder. PMID- 27692283 TI - Food allergy: Current perspectives.

AB - The mesothelium was traditionally thought to be a simple tissue with the sole function of providing a slippery, nonadhesive, and protective surface to allow easy movement of organs within their body cavities. However, our knowledge of mesothelial cell physiology is rapidly expanding, and the mesothelium is now recognized as a dynamic cellular membrane with many other important functions. When injured, mesothelial cells initiate a cascade of processes leading either to complete regeneration of the mesothelium or the development of pathologies such as adhesions. Normal mesothelial healing is unique in that, unlike with other epithelial-like surfaces, healing appears diffusely across the denuded surface, whereas for epithelium healing occurs solely at the wound edges. This is because of a free-floating population of mesothelial cells which attach to the injured serosa. Taking advantage of this phenomenon, intraperitoneal injections of mesothelial cells have been assessed for their ability to prevent adhesion formation. This review discusses some of the functions of mesothelial cells regarding maintenance of serosal integrity and outlines the mechanisms involved in mesothelial healing. In addition, the pathogenesis of adhesion formation is discussed with particular attention to the potential role of mesothelial cells in both preventing and inducing their development. PMID- 27692286 TI - Microsurgical principles and postoperative adhesions: lessons from the past. AB - "Microsurgery" is a set of principles developed to improve fertility surgery outcomes. These principles were developed progressively based on common sense and available evidence, under control of clinical feedback obtained with the use of second-look laparoscopy. Fertility outcome was the end point; significant improvement in fertility rates validated the concept clinically. Postoperative adhesion formation being a major cause of failure in fertility surgery, the concept of microsurgery predominantly addresses prevention of postoperative adhesions. In this concept, magnification with a microscope or laparoscope plays a minor role as technical facilitator. Not surprisingly, the principles to prevent adhesion formation are strikingly similar to our actual understanding: gentle tissue handling, avoiding desiccation, irrigation at room temperature, shielding abdominal contents from ambient air, meticulous hemostasis and lavage, avoiding foreign body contamination and infection, administration of dexamethasone postoperatively, and even the concept of keeping denuded areas separated by temporary adnexal or ovarian suspension. The actual concepts of peritoneal conditioning during surgery and use of dexamethasone and a barrier at the end of surgery thus confirm without exception the tenets of microsurgery. Although recent research helped to clarify the pathophysiology of adhesion formation, refined its prevention and the relative importance of each factor, the clinical end point of improvement of fertility rates remains demonstrated for only the microsurgical tenets as a whole. In conclusion, the principles of microsurgery remain fully valid as the cornerstones of reproductive microsurgery, whether performed by means of open access or laparoscopy.

PMID- 27692294 TI - Standardized cell sources and recommendations for good cell culture practices in genotoxicity testing. AB - Good cell culture practice and characterization of the cell lines used are of critical importance in in vitro genotoxicity testing. The objective of this initiative was to make continuously available stocks of the characterized isolates of the most frequently used mammalian cell lines in genotoxicity testing anywhere in the world ('IVGT' cell lines). This project was organized under the auspices of the International Life Sciences Institute (ILSI) Health and Environmental Sciences Institute (HESI) Project Committee on the Relevance and Follow-up of Positive Results in In Vitro Genetic Toxicity (IVGT) Testing. First, cell isolates were identified that are as close as possible to the isolate described in the initial publications reporting their use in genotoxicity testing. The depositors of these cell lines managed their characterization and their expansion for preparing continuously available stocks of these cells that are stored at the European Collection of Cell Cultures (ECACC, UK) and the Japanese Collection of Research Bioresources (JCRB, Japan). This publication describes how the four 'IVGT' cell lines, i.e. L5178Y TK+/- 3.7.2C, TK6, CHO-WBL and CHL/IU, were prepared for deposit at the ECACC and JCRB cell banks. Recommendations for handling these cell lines and monitoring their characteristics are also described. The growth characteristics of these cell lines (growth rates and cell cycles), their identity (karyotypes and genetic status) and ranges of background frequencies of select endpoints are also reported to help in the routine practice of genotoxicity testing using these cell lines. PMID- 27692295 TI - Characterization of urban aerosol: seasonal variation of mutagenicity and genotoxicity of PM2.5, PM1 and semi-volatile organic compounds. AB - Urban particulate matter (PM) is an environmental public health concern as it has been classified by the IARC as carcinogenic to humans (group 1) and it's well known that pollutants are more associated with the finest fractions of PM. In this study we characterize urban aerosol in Bologna, county town of Emilia Romagna in the north of Italy, collecting PM2.5, PM1 and semi-volatile organic compounds using polyurethane foam. Samples were collected in three different seasons (winter, summer and autumn) and were extracted with acetone. On these three fractions we assessed mutagenicity using Salmonella reverse mutation test and genotoxicity by alkaline comet assay and micronucleus assay in human lung cancer cell line, A549. Organic extracts were also characterized for alkanes, polycyclic aromatic hydrocarbons (PAHs), nitrated and oxygenated PAHs. We also evaluated associations between the physicochemical parameters of samples and their genotoxicity. The particulate samples, collected in autumn and winter, indicated the presence of both base pair substitution and frameshift mutagens using TA98 and TA100 strains of Salmonella typhimurium and the mutagenicity was more associated with the finest fraction. Enhanced mutagenic response was observed in the absence of enzyme activation. Only a third of comet and a half of micronucleus assays gave positive results that, unlike Salmonella's ones, are not season-related. These results were compared with environmental chemicals concentrations and we found that Salmonella's data correlated with PAHs detected on PM filters and with mass concentrations, whereas the DNA damage correlate only with PAHs extracted from polyurethane foams. The use of different assays was sensitive to detect and identify different classes of airborne mutagenic/genotoxic compounds present in aerosol, showing that monitoring air quality using this methodology is relevant. PMID- 27692296 TI - The radioprotective effect of metformin against cytotoxicity and genotoxicity induced by ionizing radiation in cultured human blood lymphocytes. AB - Metformin is a widely prescribed drug used in the treatment of patients with type 2 diabetes. In this study, the radioprotective effect of metformin was investigated against cytotoxicity and genotoxicity induced by ionizing radiation (IR) in human peripheral blood lymphocytes. Human lymphocytes were treated with metformin at concentrations 10 and 50MUM for 2h and irradiated with 6MV X-rays. The radiation antagonistic potential of metformin was assessed by MTT [3-(4,5 dimethyl-2-thiaozolyl)-2,5-diphenyl-2H tetrazolium bromide] assay, chromosomal aberration (CA) analysis, cytokinesis blocked micronucleus (CBMN) assay, and flow cytometry. Observations demonstrated a radiation-dose-dependent decrease in the percentage of cell viability after 24h. It was found that pretreatment with metformin (10 and 50MUM) increased the percentage of cell viability. A highly significant dose modifying factor (DMF) 1.35 and 1.42 was observed for 10 and 50MUM metformin, respectively. Metformin (10 and 50MUM) pretreatment significantly decreased the frequency of dicentrics (DCs), acentric fragments (AFs), rings (RIs), micronuclei (MN), and nucleoplasmic bridges (NPBs) in irradiated human peripheral blood lymphocytes. Also, treatment with metformin (10 and 50MUM) without irradiation did not increase the number of MN, NPBs, DCs, AFs, RIs, and did not show a cytostatic effect in the human peripheral blood lymphocytes. On the other hand, metformin treatment (10 and 50MUM) 2h prior to irradiation significantly reduced X-radiation-induced apoptotic incidence in human lymphocytes. The present study demonstrates metformin to be an effective radioprotector against DNA damage and apoptosis induced by IR in human lymphocytes. These data have an important application for the protection of lymphocytes from the genetic damage and side-effects induced by radiotherapy in cancer patients. PMID- 27692297 TI - The utility of the in vitro micronucleus test for evaluating the genotoxicity of natural and manmade nano-scale fibres. AB - A range of fibrous materials, including several types of asbestos and carbon fibres with nano scale diameters that had reported positive genotoxicity data (predominantly clastogenicity), were tested in the in vitro micronucleus test (OECD 487) in GLP-compliant studies in Chinese Hamster Ovary cells. Out of eight materials tested, only one (crocidolite, an asbestos fibre) gave a positive response either in the presence or absence of metabolic activation (S9) and at short (3h) or extended (24h) exposure times (p<=0.001). Our data suggest that the commonly used tests for clastogenicity in mammalian cells require extensive modification before fibrous materials are detected as positive, raising questions about the validity of these tests for detecting clastogenic and aneugenic fibrous materials. PMID- 27692298 TI - Linking genotoxicity and cytotoxicity with membrane fluidity: A comparative study in ovarian cancer cell lines following exposure to auranofin. AB - Auranofin, an organogold compound classified as an anti-rheumatic agent is under phase 2 clinical trials for re-purposing to treat recurrent epithelial ovarian cancer. We have reported earlier that Breast cancer 1, early onset (BRCA1) mutant ovarian cancer cells exhibit increased sensitivity to auranofin. BRCA1 is a DNA repair protein whose functional status is critical in the prognosis of ovarian cancer. Apart from DNA repair capability of cancer cells, membrane fluidity is also implicated in modulating resistance to chemotherapeutics. We report here that membrane fluidity influences the sensitivity of ovarian cancer cell lines, OVCAR5 and IGROV1, to auranofin. Electron spin resonance (ESR) analysis revealed a more fluidized membrane in IGROV1 compared to OVCAR5. Interestingly, IGROV1 cells were more sensitive to auranofin induced cytotoxicity than OVCAR5. In comparison to OVCAR5, IGROV1 cells also exhibited an increased number of DNA double strand breaks (DSBs) upon auranofin treatment as assessed by 53BP1 immunostaining. Furthermore, correlation analysis demonstrated a strong positive correlation (r=0.856) between membrane fluidity and auranofin sensitivity in these cell lines. Auranofin-treated IGROV1 cells also exhibited increased cellular oxidation and apoptosis. Anti-oxidant, N-acetyl cysteine (NAC) inhibited the cellular oxidation and apoptosis in auranofin-treated ovarian cancer cells suggesting reactive oxygen species (ROS) mediate the anti-cancer properties of auranofin. Overall, our study suggests that auranofin mediates its cytotoxicity via ROS production in ovarian cancer cells which correlates positively with membrane fluidity. PMID- 27692299 TI - Association of single nucleotide polymorphism with arsenic-induced skin lesions and genetic damage in exposed population of West Bengal, India. AB - Long term consumption of arsenic contaminated water causes a number of dermatological and non-dermatological health problems and cancer. In a Genome Wide Association Study (GWAS) on Bangladesh population, a significant association of asingle nucleotide polymorphism (SNP) in the C10orf32 region (rs 9527; G>A) with urinary metabolites and arsenic induced skin lesions was reported. This study aims to evaluate the association of the C10orf32 G to A polymorphism (rs9527), concerned with As3MT read-through transcription, with the development of arsenic induced skin lesions in the arsenic exposed individuals of West Bengal, India. A total of 157 individuals with characteristic skin lesions (cases) and 158 individuals without any skin lesion (controls) were recruited for this study. The G>A polymorphism (rs9527) having at least one minor allele 'A' was found to be significantly higher in cases compared to controls, implying increased risk toward the development of skin lesions. The risk genotype was also found to be significantly associated with cytogenetic damage as measured by chromosomal aberrations and micronuclei formation in lymphocytes. Hence, it can be concluded that G>A change in the C10orf32 region plays an important role in arsenic induced toxicity and susceptibility. PMID- 27692300 TI - Upper lip swelling.

PMID- 27692306 TI - Management and outcomes of vaginal bleeding and heavy menstrual bleeding in women of reproductive age on direct oral anti-factor Xa inhibitor therapy: a case series. AB - BACKGROUND: Observational data and results from post-hoc analyses in clinical trials suggest that direct oral factor Xa inhibitors might increase menstrual bleeding intensity in women of reproductive age, but the extent of this effect is unknown. We aimed to investigate the management and outcomes of vaginal bleeding complications during therapy with direct oral factor Xa inhibitors in a case series of women of reproductive age. METHODS: To identify individuals for inclusion in this case series, we searched two sources of prospectively collected data from women of reproductive age treated with direct oral factor Xa inhibitors: the non-interventional Dresden NOAC Registry (NCT01588119), which is based in the administrative district of Dresden (Saxony, Germany), and all locally archived data from phase 3 trials of direct oral factor Xa inhibitors done at University Hospital Carl Gustav Carus Dresden. Vaginal bleeding events were defined as any vaginal bleeding complications as reported by the patient. We collected data on type and dosage of anticoagulation; suspected or confirmed bleeding events, hospital admissions, and mortality; and pattern and management of vaginal bleeding events. For all cases of bleeding identified, we reviewed all available source data to identify examination results suggesting potential underlying anatomical causes of bleeding. FINDINGS: We identified 178 women of reproductive age who received direct oral factor Xa inhibitor therapy, of whom 57 had vaginal bleeding events, including 50 who received rivaroxaban, six who received apixaban, and one who received edoxaban. These 57 women had 72 vaginal bleeding events, including 59 cases of heavy menstrual bleeding and 13 bleeding events unrelated to the menstrual cycle. 51 (86%) of these heavy menstrual bleeding events (two major bleeding events, 17 clinically relevant non-major bleeding events, 32 minor bleeding events) were treated conservatively (eg, change of oral hormone therapy or reduction, temporary interruption, or discontinuation of direct oral factor Xa inhibitor) and the remaining eight (14%) events (three major bleeding events and five clinically relevant non-major bleeding events) required elective surgical or interventional treatment (hysterectomy, curettage, ovary excision, or excision of ovarian cysts). Of the 57 women, 13 (23%) had a second bleeding event and two (4%) had a third event. Nine patients had underlying anatomical abnormalities; compared with patients without abnormalities, these patients had more intense bleeding, more had recurrent bleeding (five [56%] of nine patients with abnormalities vs eight [17%] of 48 patients without abnormalities), and more needed surgical treatment for bleeding (eight [89%] of nine vs zero of 48). INTERPRETATION: Vaginal bleeding, particularly heavy menstrual bleeding, is a common complication in women of reproductive age on direct oral factor Xa inhibitor therapy. Most cases can be treated conservatively, but patients with severe or recurrent vaginal bleeding complications should be assessed for underlying anatomical abnormalities, which might require surgical or interventional treatment. Further data are needed to provide guidance on prevention and treatment of vaginal bleeding complications in this patient population. FUNDING: None. PMID- 27692305 TI - The combined role of biomarkers and interim PET scan in prediction of treatment outcome in classical Hodgkin's lymphoma: a retrospective, European, multicentre cohort study. AB - BACKGROUND: Early-interim fluorodeoxyglucose (FDG)-PET scan after two ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) chemotherapy courses (PET 2) represents the most effective predictor of treatment outcome in classical Hodgkin's lymphoma. We aimed to assess the predictive value of PET-2 combined with tissue biomarkers in neoplastic and microenvironmental cells for this disease. METHODS: We enrolled 208 patients with classical Hodgkin's lymphoma and treated with ABVD (training set), from Jan 1, 2002, to Dec 31, 2009, and validated the results in a fully matched independent cohort of 102 patients with classical Hodgkin's lymphoma (validation set), enrolled from Jan 1, 2008, to Dec 31, 2012. The inclusion criteria for both the training and validation sets were: the availability of a representative formalin-fixed, paraffin-embedded tissue sample collected at diagnosis; treatment with ABVD with or without radiotherapy; baseline staging and interim restaging after two ABVD courses with FDG-PET; no treatment change based solely on interim PET result; and HIV-negative status. We used Cox multivariate analysis classification and regression tree (CART) to compare the predictive values of these markers with that of PET-2 and to assess the biomarkers' ability to correctly classify patients whose outcome was incorrectly predicted by PET-2. FINDINGS: In multivariate analysis, PET-2 was the only factor able to predict both progression-free survival (hazard ratio [HR] 33.3 [95% CI 13.6-83.3]; p<0.0001) and overall survival (HR 31.3 [95% CI 3.7 58.9]; p=0.002). In the training set, no factor had a stronger adverse predictive value than a positive PET-2 scan and none was able to correctly reclassify PET-2 positive patients. In PET-2 negative patients, expression of CD68 (>=25%) and PD1 (diffuse or rosetting pattern) in microenvironmental cells, and STAT1 negativity in Hodgkin Reed Sternberg cells identified a subset of PET-2 negative patients with a 3 year progression-free survival significantly lower than that of the remaining PET-2 negative population (21 [64%] of 33 [95% CI 45.2-79.0] vs 130 [95%] of 137 [95% CI 89.4-97.7]; p<0.0001). These findings were reproduced in the validation set. INTERPRETATION: The CART algorithm correctly predicted the response to treatment in more than a half of patients who had a relapse or disease progression despite a negative PET-2 scan, thus increasing the negative predictive value of PET-2. In keeping with preliminary results from interim PET response adapted clinical trials of patients with advanced Hodgkin's lymphoma, there might be a non-negligible proportion of treatment failures in the interim PET negative group treated with standard ABVD.

PMID- 27692307 TI - Topical Fish Oil Application Coupling with Therapeutic Ultrasound Improves Tendon Healing. AB - Fish oil has been shown to promote collagen synthesis, and hence, connective tissue healing. Therapeutic ultrasound is commonly used to treat soft tissue injuries. This study aimed to investigate the therapeutic effect of topical fish oil on the management of Achilles tendon rupture, comparing normal therapeutic ultrasound with a combination of ultrasound and fish oil. Eighty-five Sprague Dawley rats underwent surgical hemitenotomy of the right medial Achilles tendon. The rats received daily treatment of either topical placebo ointment (control group [CON]), topical fish oil (FO), therapeutic ultrasound (US) or ultrasound with fish oil as the coupling medium (FU). The treatment started on post-surgical day 2 over a 2-wk or 4-wk period. On days 15 and 29, the rats were sacrificed and their Achilles tendons were tested for structural stiffness, ultimate tensile strength (UTS) and energy absorption capacity. At 2 wk, only US showed higher normalized UTS compared with CON (p < 0.05). At 4 wk, both US and FU demonstrated better UTS (p < 0.05), while both FO and FU had improved in structural stiffness (p < 0.05). Four wk of treatment with ultrasound using fish oil as coupling medium showed improvement in both structural stiffness and UTS (p < 0.05). PMID- 27692308 TI - Body condition is negatively associated with infection with Syngamus trachea in the ring-necked pheasant (Phasianus colchicus). AB - The role that parasites play in regulating animal populations is debated, however recent research hints at their pervasiveness among free-living animal populations. Parasites exert both direct and indirect effects on host populations, and can act to regulate populations. The Ring-necked pheasant is an important game-bird species in the UK, and large numbers of birds are released annually. The impact of the ubiquitous tracheal nematode, Syngamus trachea on pheasant populations through effects on host condition was assessed on two pheasant estates in the south west of England. Pheasants infected with S. trachea demonstrated a significant reduction in host condition compared with uninfected controls, with as few as one pair of worms per bird. Although there was no difference in worm burden between sexes, analysis of regression slopes revealed there was a significant difference between sexes in the magnitude of the effect of increasing worm burden on host condition, with detectable effects observed in hosts with one and three pairs of worms for males and females respectively. The observed reductions in host condition in birds with even sub-clinical infections could be the cause of poor reproductive success and survival of pheasants post release. PMID- 27692309 TI - Repeatability of strongyle egg counts in naturally infected horses. AB - The selective treatment of horses is used to decrease the number of anthelmintic treatments by only treating a proportion of animals in the population. One way to select animals for treatment is to identify low and high egg-shedders using faecal egg counts (FEC); then to treat only the high egg-shedders. The value of this method is enhanced if differences among individuals in the level of egg shedding remain consistent over time. One way to assess the stability of the rankings of animals over time is to measure the repeatability which is defined as the variance between horses divided by the total variance. The repeatability varies between 0 (no consistency in the values) to 1 (perfect consistency). To determine the repeatability of egg-shedding in naturally infected horses over time, 2637 FEC and raw egg counts (REC; i.e. originally counted eggs without multiplication factor) from 303 horses were analysed. The distribution of FEC was more overdispersed than a Poisson distribution. Therefore, a negative-binomial model was used. The within-horse-repeatability of RECs was 0.52. In a second analysis, we excluded horses that were treated with anthelmintic drugs during the study by eliminating all REC within the egg-reappearance-period. Here, the within horse-repeatability was very similar at 0.53. The results show that egg-shedding of individual horses stays fairly consistent over time. They also show that animals which shed relatively high numbers of nematode eggs can be identified and targeted for treatment.

AB - Literature documenting the growth and development of Parascaris spp. infections was used to develop a model describing worm dynamics in the young horse. The model incorporates four main variables; the rate at which larvae migrate through host tissues to return to the small intestine, the proportion of migrating larvae which succeed in returning to the small intestine, the rate of growth in size of maturing and adult worms and the survival rate of maturing and adult worms. In addition, the number of eggs laid each day by adult female worms is calculated as a function of worm size (length) and is used to calculate faecal egg output of the foal. Published data describing the rate of migration through host tissues, and the growth of worms following their return to the small intestine, was used to derive relationships describing these processes. However, only limited data exists relating the survival of migrating larvae and mature worms in the intestine to host age and experience of infection. Therefore, relationships and coefficients describing these variables were modified so that output aligned with published experimental results. As a consequence, the model has not yet been evaluated against an independent data set, and so remains as the best 'current hypothesis' for the dynamics of this parasite. Hopefully, future experiments designed to test specific assumptions and outputs of the model will lead to a better understanding of the biology of this important parasite. For example, the most influential variable in determining model output is the survival rate of worms in the small intestine. In the model, worm survival declines in response to both the increasing age of the horse and the increasing cumulative length of worms in the intestine (used as a proxy for crowding). Given the importance of this variable to model behaviour and the paucity of experimental data on this topic this would seem a priority for future study. Initial experiments using the model suggest that a single anthelmintic treatment, administered soon after patency of initial infection, may effectively control environmental contamination with Parascaris spp. eggs while allowing a small 'refugia' of susceptibility to delay the emergence of anthelmintic resistance. Further evaluations of the practicality of this approach may be worthwhile. PMID- 27692311 TI - Genetic characterization of Cryptosporidium in animal and human isolates from Jordan. AB - Little is known about the epidemiology of Cryptosporidium in Jordan and to date, only one genotyping study has been conducted on Cryptosporidium isolates from Jordanian children. In the present study, a total of 284 faecal samples from Jordanian cattle, sheep, goats and chicken and 48 human faecal samples were screened for the presence of Cryptosporidium using an 18S quantitative PCR (qPCR) and a C. parvum/C. hominis specific qPCR at a lectin locus. Of these, 37 of 284 animal faecal samples were positive by qPCR at the 18S locus giving an overall prevalence of 11.6%. The point prevalence of Cryptosporidium in chickens, sheep, horses, cattle and goats ranged from 4.8% (chickens) to 18.7% (cattle). A total of six species were detected; C. xiaoi (n=9),C. andersoni (n=7),C. ryanae (n=5),C. parvum (n=4),C. baileyi (n=1) and a genetically distinct and potentially novel species in two isolates from horses. Sub-genotype analysis of the 4 C. parvum isolates at the 60-kDa glycoprotein (gp60) locus identified subtype IIaA19G2R1 (n=2) and IIaA16GR1 (n=2). For the human samples, 4 positives (8.3% prevalence) were detected. Of these, two were C. parvum (subtypes IIdA20G1 and IIaA15G2R1) and two were C. hominis (subtypes 1bA9G3 and 1bA10G2R2). Further studies are required to better understand the epidemiology and transmission of Cryptosporidium in Jordan. PMID- 27692312 TI - Synergistic action of fatty acids, sulphides and stilbene against acaricide resistant Rhipicephalus microplus ticks. AB - Six compounds in a methanolic extract of Petiveria alliacea stem (cis-stilbene; benzyl disulphide; benzyl trisulphide; and methyl esters of hexadecanoic acid, octadecadienoic acid and octadecenoic acid) are known to exercise acaricide activity against cattle tick Rhipicephalus microplus larvae and adults. The synergistic effect of 57 combinations of these six compounds on acaricide activity against R. microplus was evaluated. Larvae immersion tests produced the lethal concentrations needed to kill 50% (LC50) and 99% (LC99) of the population. Adult immersion tests produced rates (%) for mortality, oviposition inhibition and eclosion inhibition. Individually, none of the compounds (1% concentration) exhibited acaricide activity (mortality <=2.3%). When combined, however, nine mixtures exhibited a synergistic increase in activity, with high mortality rates (>=92%) in larvae. Values for LC50 ranged from 0.07 to 0.51% and those for LC99 from 0.66 to 5.16%. Thirty six compound mixtures had no significant activity (mortality <=30%) against larvae. Two mixtures exhibited synergism against adults, with high rates (>=92%) of oviposition inhibition. The mixtures based on the benzyl disulphide+benzyl trisulphide pairing produced a synergistic effect against acaricide-resistant R. microplus larva and adults, and are therefore the most promising combination for controlling this ubiquitous ectoparasite. PMID- 27692313 TI - Toxoplasma gondii detection in cattle: A slaughterhouse survey. AB - Toxoplasmosis is a zoonotic disease caused by the protozoan parasite Toxoplasma gondii. Ingestion of raw or undercooked meat containing viable cysts has been suggested to be a major source of T. gondii infection in humans. Suboptimal performance of serological assays in cattle has traditionally precluded accurate quantification of the extent to which cattle populations are infected and their meat harbour tissue cysts. In the absence of accurate estimates of the level of infection in the animal population, assessments of likely human exposure through the consumption of cattle meat remain highly speculative. Following the development of novel and sensitive molecular methods that can be applied to the relatively large numbers of samples required in observational studies, the first quantitative estimates of the frequency of T. gondii in meat samples from naturally infected cattle have become available recently. Such estimates are critical for the development of quantitative risk assessment models that could be used to inform food safety policies. The aim of this study was to generate the first estimates of the prevalence of T. gondii infection in a sample of cattle exposed to natural levels of infection and slaughtered for human consumption in the UK under commercial conditions. Such estimates provide great value to the global assessment of T. gondii burden given the scarcity of data available on the frequency of natural infection in cattle populations worldwide. Between October 2015 and January 2016 diaphragm samples were collected from 305 animals, slaughtered in ten commercial slaughterhouses across the UK. Movement histories showed that the animals sampled (41.6% females and 58.4% males) had passed through a total of 614 farms and 40 livestock markets across the country. Five animals (1.6%) were deemed positive for T. gondii following magnetic capture real time PCR, confirmed by amplicon sequencing. The true prevalence of infection was estimated to be 1.79%. All positive animals were male, none of whom had been on the same farm and/or livestock market before slaughter and there was no apparent geographic pattern. The results from this study suggest a low level of infection in cattle raised and slaughtered in the UK and can be used to populate the first stages of formal risk assessments to quantify the likely extent of human exposure to T. gondii through the consumption of beef with relevance to the UK, EU and rest of the world. PMID- 27692314 TI - Comparison of genotypes of Toxoplasma gondii in domestic cats from Australia with latent infection or clinical toxoplasmosis. AB - Whether Toxoplasma gondii genotype is associated with disease severity in naturally occurring toxoplasmosis in domestic cats is unknown. The aim of this study was to compare genotypes of T. gondii in latently infected cats with those in cats with clinical toxoplasmosis. Results of a PCR targeting the B1 gene to detect T. gondii DNA were positive in tissue samples from 11 of 17 (65%) seropositive cats tested including four with clinical toxoplasmosis and seven with latent infections, as determined by serology, histologic findings and immunohistochemistry. Three of the four cats with clinical toxoplasmosis were immunosuppressed. Complete genotyping was performed in seven cats using PCR-RFLP at 12 loci (SAG1, 5'SAG2 and 3'SAG2, altSAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1 and Apico) and direct sequencing of the multi-copy B1 gene. Partial genotyping using six loci was performed in one cat with latent infection. T. gondii type II (ToxoDB genotype #3) was determined in four cats with clinical toxoplasmosis and three cats with latent toxoplasmosis Novel T. gondii B1 gene polymorphisms were detected in two strains (at nucleotide posititions 233, 366 and 595) and a B1 gene polymorphism unique to Australia was identified in another (guanine/adenine at nucleotide position 378). One cat was co-infected with two or more type-II like strains at 3'SAG2. The results of this study suggest that the infecting T. gondii genotype, based on these 12 loci, is not a determinant of clinical disease in cats naturally infected with T. gondii and type II strains are prevalent in Australia. PMID- 27692315 TI - Protection of ewes against Teladorsagia circumcincta infection in the periparturient period by vaccination with recombinant antigens. AB - Teladorsagiosis is a major production-limiting disease in ruminants in temperate regions throughout the world and one of the key interventions in the management of the disease is the prevention of pasture contamination with Teladorsagia circumcincta eggs by ewes during the periparturient relaxation in immunity which occurs in the period around lambing. Here, we describe the immunisation of twin bearing ewes with a T. circumcincta recombinant subunit vaccine and the impact that vaccination has on their immune responses and shedding of parasite eggs during a continuous T. circumcincta challenge period spanning late gestation and lactation. In ewes which displayed a clear periparturient relaxation in immunity, vaccination resulted in a 45% reduction in mean cumulative faecal egg count (cFEC, p=0.027) compared to control (immunised with adjuvant only) ewes. Recombinant antigen-specific IgG and IgA, which bound each of the vaccine antigens, were detected in the serum of vaccinated ewes following each immunisation and in colostrum taken from vaccinated ewes post-partum whereas low levels of antigen-specific IgG were detected in serum and colostrum from control ewes. Antigen-specific IgG and IgA levels in blood collected within 48h of birth from lambs largely reflected those in the colostrum of their ewes. PMID- 27692316 TI - Acaricidal activity of methanol extract of Acmella oleracea L. (Asteraceae) and spilanthol on Rhipicephalus microplus (Acari: Ixodidae) and Dermacentor nitens (Acari: Ixodidae). AB - We evaluated the acaricidal activity of Acmella oleracea methanol extract and spilanthol on Rhipicephalus microplus and Dermacentor nitens. The extract was made through maceration with methanol. From this extract, a dichloromethane fraction with 99% spilanthol was obtained and tested on R. microplus larvae and engorged females and D. nitens larvae. For evaluation against larvae, the modified larval packet test was used, and both the methanol extract and dichloromethane fraction were tested at concentrations of 0.2-50mg/mL. The modified larval packet test was also used in the lethal time (LT) test, with the methanol extract at a concentration of 12.5mg/mL and the percentage mortality was assessed after 15, 30, 45, 60, 75, 90, 120min and 24h. The 50% lethal time calculation (LT50) was performed in this test. The engorged female test was performed with R. microplus only, at concentrations of 25-200mg/mL for methanol extract and 2.5-20.0mg/mL for spilanthol. The methanol extract caused 100% mortality of the R. microplus and D. nitens larvae at concentrations of 3.1 and 12.5mg/mL, respectively. Spilanthol resulted in 100% mortality of R. microplus larvae at concentration of 1.6mg/mL and of D. nitens at 12.5mg/mL. In the lethal time assay using the methanol extract, the mortality rate was 100% for R. microplus and D. nitens larvae after 120min and 24h, with LT50 values of 38 and 57min, respectively. In the test of females, the egg mass weight and the hatching percentage of the groups treated with concentrations equal to or higher than 50.0mg/mL of methanol extract were significantly reduced (p<0.05), while for spilanthol, the reduction of the egg mass weight and hatching percentage occurred from concentrations of 10.0mg/mL and 2.5mg/mL, respectively. Females treated with 200.0mg/mL of extract died before starting oviposition, resulting in 100% effectiveness, while the best efficacy for spilanthol was 92.9% at a concentration of 20.0mg/mL. Thus we conclude that the methanol extract of A. oleracea and spilanthol have acaricidal activity against R. microplus and D. nitens. PMID- 27692317 TI - Lungworm Heterostrongylus heterostrongylus Travassos, 1925 from the black-eared opossum in South America: Morphologic, histopathological and phylogenetic aspects. AB - Nematode parasites of the cardiopulmonary system of livestock and pet animals have been receiving attention due to the pathogenic effects they produce in the course of the infection. However, parasitism in wild animals by metastrongilid nematodes has been neglected, resulting in potential risk to wildlife. Heterostrongylus heterostrongylus is the etiological agent of bronchial pneumonia in the black-eared opossum, Didelphis aurita, a widely distributed marsupial frequently reported to inhabit areas from wild environments to peri-urban spaces. In this study, we reassessed the taxonomy of H. heterostrongylus, describing and comparing morphology of L1 and L3 larvae and adult worms with closely related angiostrongilids, and inferring phylogenetic affinities within the family Angiostrongylidae; we also detailed histopathological reactions under natural infection. Ultrastructural morphology and light microscopy confirmed cephalic structures with well-developed trilobed lips, patterns of caudal bursa rays, spicules shape, terminal anal aperture and presence of the ventral protuberance in L3 larvae, characteristics present for the family Angiostrongylidae. Our molecular phylogenetic analyses, based on the partial small subunit (SSU) 18S rRNA gene, suggested that H. heterostrongylus and Didelphostrongylus hayesi are closely related. Pathological analyses agreed with previous findings, showing that cardiopulmonary parasitism provokes verminous pneumonia and mucous bronchiolitis with hypertrophy of the smooth bronchiolar muscle. These data confirmed that H. heterostrongylus represents a pulmonary pathogen in D. aurita, produces severe pathological effects, and may represent risk to domestic and wild animals. PMID- 27692318 TI - First report of the in vitro nematicidal effects of camel milk. AB - Antipathogenic properties of camel milk have been investigated to substitute for drugs hence overcome drug resistance. The main objective of this present study was to investigate the anthelmintic activity of camel milk in relationship to its chemical composition. In vitro anthelmintic effects of camel milk against Haemonchus contortus from sheep were ascertained by egg hatching and worm motility inhibitions in comparison to milks from cow, ewe and goat as well as a reference drug albendazole. Chemical composition revealed that camel milk has higher contents of protective protein (lactoferrin) and vitamin C than other species' milk. It showed ovicidal activity at all tested concentrations and completely inhibited egg hatching at a concentration close to 100mg/mL (inhibitory concentration (IC50)=42.39mg/mL). Camel milk revealed in vitro activity against adult parasites in terms of the paralysis and/or death of the worms at different hours post treatment. After 8h of exposure, it induced 100% mortality at the highest tested concentration. There was 82.3% immobility of worms in albendazole 8h post-exposition. No such effects were seen with the other species' milks. Bioactive compounds such as lactoferrin and vitamin C may be involved in such an effect. To our knowledge, these results depict for the first time that camel milk possesses in vitro anthelmintic properties and further in vitro and in vivo trials against different parasite species and stages are required to make use of this milk for the control of gastrointestinal nematode parasites. PMID- 27692319 TI - Anti-helminthic activity of Momordica charantia L. against Fasciola hepatica eggs after twelve days of incubation in vitro. AB - Fasciolosis, a parasitic disease caused by the trematode Fasciola hepatica underreported is expanding both in human and animal population, throughout the world. The constant use of synthetic drugs to treat this condition has led to the natural selection of resistant strains of the parasite. Hence, there is a growing focus on the potential anti-helminthic properties of medicinal plants and phytopharmaceuticals. The current study assessed the potential anti-fasciolicide action of Momordica charantia leaf extracts and fractions on the eggs of F. hepatica parasites. The lyophilized crude extract (CE) of M. charantia leaves and its sub-fractions, obtained from liquid-liquid partitioning with organic solvents, were analysed by High Performance Liquid Chromatography (HPLC), suspended in 1% DMSO and used in in vitro tests. Quadruplicates of 50F. hepatica eggs were incubated at 23 degrees C with M. charantia leaf CE in different concentrations. After 12days no larvae were formed in eggs incubated with CE concentrations above 12.5mg/mL. Eggs incubated with CE sub-fractions at concentrations of 1000, 100, 10, 1, 0.1, 0.01MUg/mL affected embryonic development, with n-butanol presenting the strongest inhibition of miracidia formation. In contrast, on the 12th day, 90% of the miracidia hatched in the control experiments using 0.03% DMSO whereas embryogenesis was completely abolished with any concentration of albendazole sulphoxide ABZ(SO). Chemical analysis of the CE and sub-fractions revealed a prominent presence of flavonoids. HPLC-MS confirmed Quercetin to be one of the main flavonoids present in the CE and the n-butanol subfraction. This is the first study to analyse the potential anti-fasciolicide action of M. charantia leaf CE and subfractions. PMID- 27692320 TI - Evaluation of pharmacokinetics and efficacy of ivermectin following oral administration in dogs against experimental infection of Ctenocephalides felis felis and Rhipicephalus sanguineus. AB - With the increasing number of pets in home the human-animal relationship is increasingly close and care about control disease growing. Ivermectin (IVM) is frequently used because its proven safety. IVM is recommended for the treatment of demodectic scabies and prevention of heartworm in dogs, but informally is extremely used to control of Ctenocephalides felis felis and Rhipicephalus sanguineus. The aim of this study is evaluate the use of IVM in dogs, by the oral route at 0.6MUg/kg dose, against experimental infection of these parasites using the construction of the plasma concentration curve and efficacy study. A IVM quantification method in canine plasma using HPLC-FL was developed and validated based on RE n degrees 899/03 ANVISA. The samples collected during the efficacy test was analyzed by this validated method and prove Cmax of 350ng/mL at 4h (tmax) and AUC of 8411ng/h/mL. Spite of formulation have shown good absorption, the highest efficiency values found for Rhipcephalus sanguineus and Ctenocephalides felis felis were very low, 35% and 67% respectively, demonstrating this not be the most appropriate treatment for the control of these parasites. PMID- 27692321 TI - Ectoparasites of free-roaming domestic cats in the central United States. AB - Free-roaming domestic cat (Felis catus) populations serve as a valuable resource for studying ectoparasite prevalence. While they share a similar environment as owned cats, free-roaming cats do not receive routine veterinary care or ectoparasiticide application, giving insight into parasite risks for owned animals. We examined up to 673 infested cats presented to a trap-neuter-return (TNR) clinic in the central United States. Ectoparasite prevalences on cats were as follows: fleas (71.6%), ticks (18.7%), Felicola subrostratus (1.0%), Cheyletiella blakei (0.9%), and Otodectes cynotis (19.3%). Fleas, ticks, and O. cynotis were found in all months sampled. A total of 1117 fleas were recovered from 322 infested cats. The predominate flea recovered from cats was Ctenocephalides felis (97.2%) followed by Pulex spp. (2.8%), Cediopsylla simplex (0.6%), and Nosopsyllus fasciatus (0.6%). A total of 373 ticks were recovered from 126 infested cats. The predominate tick species was Amblyomma americanum (65.9%) followed by Ixodes scapularis (32.5%), Dermacentor variabilis (10.3%), and Rhipicephalus sanguineus (0.8%). Immature tick stages accounted for 54.7% of all ticks found, highlighting an under-appreciated source of tick burden on domestic cats. The results of this study emphasize the importance of year-round use of ectoparasiticides with both insecticidal and acaricidal activity on domestic cats. PMID- 27692322 TI - TLR-2 and TLR-4 transcriptions in unstimulated blood from dogs with leishmaniosis due to Leishmania infantum at the time of diagnosis and during follow-up treatment. AB - Innate immunity, in particular, the role of toll-like receptors (TLRs), has not been extensively studied in canine L. infantum infection. The main aim of this study was to determine the transcription of TLR2 and TLR4 in the blood of dogs with natural clinical leishmaniosis at the time of diagnosis and during treatment follow-up and subsequently correlate these findings with clinical, serological and parasitological data. Forty-six Leishmania-seropositive sick dogs with a high antibody level at the time of diagnosis were studied and compared with 34 healthy seronegative dogs. Twenty-two of these sick dogs were treated with meglumine antimoniate and allopurinol and followed-up at 30, 180 and 365days following the start of treatment. Clinical status was defined by a thorough physical examination, complete blood count, biochemistry profile, electrophoresis of serum proteins, and urinary protein/creatinine ratio (UPC). EDTA blood was stored in RNAlater(r) solution before RNA extraction and cDNA production were performed. TLR2, TLR4 and three reference genes (HPRT-1, CG14980 and SDHA) were studied in each blood sample by real time PCR. The relative quantification of TLR2 was higher (mean 3.5) in sick dogs when compared with seronegative healthy dogs (mean 1.3; P=0.0001) while the relative quantification of TLR4 was similar in both groups. In addition, the relative quantification of TLR2 significantly decreased during follow-up at all time points compared with day 0 whereas no changes were observed with TLR4 transcription. A significant positive correlation was noted between TLR2 and UPC, total protein, beta and gamma globulins, specific L. infantum antibodies and blood parasite load while a negative correlation was observed with albumin, albumin/globulin ratio, hematocrit and hemoglobin. TLR4 transcript did not correlate with any parameter. These findings indicate an up regulation of TLR2 transcription in unstimulated blood in naturally infected sick dogs as compared to healthy dogs suggesting active innate immune and proinflammatory responses. In addition, TLR2 transcription is reduced with clinical improvement during treatment. In contrast, TLR4 transcription appears to be similar among groups at the time of diagnosis with no changes during treatment follow-up suggesting a less important role for this TLR in clinical canine leishmaniosis. PMID- 27692323 TI - The association between seizures and deposition of collagen in the brain in porcine Taenia solium neurocysticercosis. AB - Neurocysticercosis caused by infection with Taenia solium is a significant cause of epilepsy and seizures in humans. The aim of this study was to assess the association between seizures and the deposition of collagen in brain tissue in pigs with T. solium neurocysticercosis. In total 78 brain tissue sections from seven pigs were examined histopathologically i.e. two pigs with epileptic seizures and T. solium cysts, four pigs without seizures but with cysts, and one non-infected control pig. Pigs with epileptic seizures had a larger amount of collagen in their brain tissue, showing as large fibrotic scars and moderate amount of collagen deposited around cysts, compared to pigs without seizures and the negative control pig. Our results indicate that collagen is likely to play a considerable part in the pathogenesis of seizures in T. solium neurocysticercosis. PMID- 27692324 TI - Genetic characterization of Neospora caninum from aborted bovine foetuses in Aguascalientes, Mexico. AB - The cyst-forming protozoan parasite Neospora caninum is one of the main causes of bovine abortion worldwide and is of great economic importance in the cattle industry. Recent studies have revealed extensive genetic variation among N. caninum isolates based on multilocus microsatellite genotyping. Currently, the most extensive study reported is based on the N. caninum genotyping of 96 samples from four countries on two continents (Spain, Argentina, Germany and Scotland) that demonstrate different clusters of multilocus genotypes (MLGs) implicated in cattle abortions as well as the population sub-structuring of N. caninum, which is partially associated with the geographical origin. The aim of this study was to genotype N. caninum from aborted bovine foetuses that originated from Mexico within the region of Aguascalientes and to investigate their genetic diversity. Parasite DNA was detected in 27 out of the 63 analysed foetuses recovered from 10 different herds. Complete or nearly complete profiles based on 9 microsatellite markers were obtained from 11 samples. Diverse N. caninum MLGs were implicated in the occurrence of abortion in each herd. All of the Mexican MLGs differed from the MLGs previously determined for the Argentinean, Spanish, German and Scottish N. caninum populations. The Mexican MLGs failed to cluster by eBURST analyses. The MLG relationships using PCoA showed a close genetic relationship between the Spanish population and a portion of the Mexican population, but a more distant genetic relationship with the Argentinean genotypes. These results demonstrate the genetic diversity of N. caninum in the studied areas that differed from other populations of N. caninum around the world. PMID- 27692325 TI - Angiostrongylus chabaudi in felids: New findings and a review of the literature. AB - Cardiopulmonary infections by Angiostrongylus chabaudi affect domestic and wild felids but, due to limited information on the biology of this nematode, its pathogenicity remains unclear. This article describes the histopathological alterations associated with Angiostrongylus infection in a wildcat from Bulgaria, and reviews current literature on this feline angiostrongylid. Nematodes were isolated from lung lavage and faecal samples of a road killed wildcat in Southern Bulgaria. The morphological identification of parasite larvae as A. chabaudi was confirmed by molecular analysis of part of the 18S ribosomal RNA gene. Upon histopathological examination, severe granulomatous pneumonia, ranging from multifocal to coalescing, and pulmonary vascular lesions were observed. Extensive alveolar collapse, alveolar emphysematous changes, parenchymal haemorrhages and small artery wall hyperplasia were observed in the parenchyma adjacent to the granulomas. Histopathological examination revealed the presence of cross-sections of adult female parasites within the lumen of the pulmonary artery branches, the intima altered markedly by subendothelial proliferation and oedematous changes. This study compliments current knowledge of the pathogenesis of feline angiostrongylosis by A. chabaudi in wildcats, as well as of the distribution of this little-known parasite. PMID- 27692327 TI - Papaya latex supernatant has a potent effect on the free-living stages of equid cyathostomins in vitro. AB - The control of equid gastrointestinal nematodes in developed countries, in particular the cyathostomins, is threatened by high levels of anthelmintic resistance. In recent years, there has been increasing interest in the evaluation of traditional 'ethnoveterinary' medicines as alternatives to chemical anthelmintics. The cysteine proteinases (CPs), a group of enzymes derived from fruits such as papaya (Carica papaya), pineapple (Ananas comosus) and figs (Ficus spp.), have shown good efficacy against adult stages of a range of parasitic nematodes, in vitro and in vivo. The efficacy of CPs against cyathostomins remains to be explored. In this study, the efficacy of a crude preparation of CPs, papaya latex supernatant (PLS), against the free-living stages of cyathostomins was evaluated using two in vitro tests, the egg hatch test (EHT) and the larval migration inhibition test (LMIT). It was demonstrated that PLS had a potent effect in the EHT, with EC-50 values in the range of 0.12-0.22MUM. At concentrations above 6.25MUM the eggs did not develop, below this concentration the L1 developed but they lost integrity of the cuticle upon hatching. These effects were inhibited by pre-incubation of PLS with the CP inhibitor L-trans epoxysuccinyl-l-leucylamido-(4-guanidino butane) (E64), indicating that CPs were responsible for the anti-parasitic activity. A dose-dependent inhibition of migration of third stage larvae (L3) in the LMIT was demonstrated at higher concentrations of PLS, with EC-50 values in the range of 67.35-106.31MUM. Incubation of PLS with E64 prior to use in the LMIT did not reverse the anti migratory effect, suggesting that CPs were not responsible for the reduced migration of cyathostomin L3 and that PLS also contains an additional active compound. This is the first report of PLS and/or CPs showing activity against the free-living stages of a parasitic helminth. In addition, it suggests that cyathostomins are highly sensitive to the effects of CPs and further evaluation of their efficacy against parasitic stages and in vivo are strongly indicated. PMID- 27692326 TI - Resistance of Haemonchus sp. to monepantel and reduced efficacy of a derquantel / abamectin combination confirmed in sheep in NSW, Australia. AB - Early in 2015, sheep in a summer rainfall area of NSW, Australia, displayed signs of haemonchosis despite treatment with monepantel. A faecal egg count reduction test (FECRT) was performed on yearlings with natural field infections using various anthelmintics. Only a four-way combination drench achieved a reduction in faecal egg count (FEC) greater than 95%. The combination contained abamectin, albendazole, levamisole and closantel. Treatments with a derquantel/abamectin combination, monepantel and moxidectin reduced FECs by 93, 31, and 30% respectively. Sheep treated with abamectin displayed an increase in FEC of 22%. Larval differentiation counts conducted 10days post-treatment showed that 100% of survivors were Haemonchus sp. This result confirms for the first time monepantel resistant Haemonchus in sheep in NSW, and is amongst the first of the Australian cases in sheep not associated with goats. A second FECRT was performed using sheep from the moxidectin and abamectin treatment groups in the first FECRT. In this second FECRT, monepantel treatment reduced FECs by 51% and 29% in the sheep previously treated with moxidectin and abamectin respectively. This suggests monepantel, in combination with moxidectin, may give some control against severely abamectin resistant Haemonchus. PMID- 27692328 TI - Efficacy of closantel against ivermectin- and fenbendazole-resistant Haemonchus sp. in sheep in Ontario, Canada. AB - In Ontario, Canada, widespread resistance to ivermectin and fenbendazole, the only readily available ovine anthelmintics, has been documented, primarily in Haemonchus sp. In other parts of the world, closantel has been used to control such infections; however, the drug was not currently licensed for use in Canada and the USA. A randomized controlled trial was conducted on six client-owned farms in Ontario in 2013 and 2014 to determine the efficacy of closantel (Flukiver(r) 5% Oral Suspension, Elanco Animal Health, 10mg/kg bodyweight) against ivermectin- and fenbendazole-resistant Haemonchus sp. infections in periparturient ewes and grazing lambs. Three farms were randomly assigned to treat all ewes, and three farms were randomly assigned to selectively treat individual ewes at lambing, using predetermined criteria. Fecal samples were collected from a minimum of 15 randomly selected ewes and 13 lambs per group on each farm at the time of treatment and approximately 14days later. Trichostrongyle-type fecal egg counts (FEC) were performed using a modified McMaster technique with a lower detection limit of 8.3 eggs per gram of feces (epg). Haemonchus-specific FECs were determined by multiplying FECs by the proportion of Haemonchus sp. identified from coproculture for each farm; Haemonchus-specific FEC reductions were calculated for each farm. Twenty grazing lambs had FECs conducted monthly, and when mean monthly FECs surpassed 200 epg, all lambs were randomly allocated to either closantel, positive control (ivermectin, fenbendazole, or levamisole) or negative control groups. Pre treatment Haemonchus-specific mean FECs ranged from 27 to 3359 epg in ewes and 0 5698 epg in lambs. Efficacy of closantel against Haemonchus sp. ranged from 99% (95% CI: 97%-99%) to 100% in recently lambed ewes on all farms in both years (total n=274 ewes), and from 99% (95% CI: 98%-99%) to 100% in grazing lambs in both years on all but one farm (total n=171 lambs). On the latter farm, a whole flock treated farm, closantel efficacy in grazing lambs was 84% (95%CI: 81%-88%) in the first year, but 100% in the second year. Levamisole was effective against overall GIN in lambs on only two farms. Ivermectin and fenbendazole resistance continued to be present, particularly in Haemonchus sp. Closantel had excellent efficacy against Haemonchus sp. over the two year study period, regardless of treatment group, and therefore should be considered one viable component of sustainable integrated parasite control programs for farms with documented anthelmintic resistance and problems with haemonchosis. PMID- 27692329 TI - Greater intensity and frequency of Cryptosporidium and Giardia oocyst shedding beyond the neonatal period is associated with reductions in growth, carcase weight and dressing efficiency in sheep. AB - Associations between intensity and frequency of Cryptosporidium and Giardia shedding with growth, carcase weight and dressing% were investigated using a longitudinal study of 1182 lambs on eight Australian farms. Live weight was recorded and faecal samples were collected on three sampling occasions; weaning (approximately 12 weeks of age), post-weaning (approximately 19 weeks) and pre slaughter (approximately 29 weeks). Hot standard carcase weight (HSCW) and dressing% were measured at slaughter. Faecal samples were screened for presence and concentration of Cryptosporidium, Giardia and Haemonchus oocysts using a quantitative PCR. Trichostrongylid eggs were quantified with modified McMaster faecal worm egg count (WEC). Protozoan shedding intensity was categorised as high (above median oocyst concentration in positive sheep), low (below median oocyst concentration in positive sheep) or not detected. Shedding was also categorised for shedding type (no shedding, single Giardia infection, single Cryptosporidium infection, concurrent Giardia and Cryptosporidium infection) and lambs were categorised for frequency of shedding (shedding identified on 0, 1, 2 or 3 occasions). Associations of parasite shedding intensity category, shedding type, shedding frequency, WEC and Haemonchus status (positive or negative) with lamb production were assessed using general linear models (HSCW and dressing%) and linear mixed effects models (live weight). High Cryptosporidium parvum shedding was associated with lower live weight, ranging 2.31-4.52kg over the 3 sampling occasions. Cryptosporidium parvum shedding was associated with less HSCW in high (3.22kg less) and low (3.22kg less) shedding lambs post-weaning, and high (2.21kg less) and low (2.60kg less) shedding lambs pre-slaughter as well as lower dressing% (2.7% lower in high shedding lambs post-weaning). Cryptosporidium (all species) shedding pre-slaughter was associated with reduced dressing% in both high (1.25% lower) and low (1.21% lower) shedding lambs. Giardia shedding pre slaughter was associated with 0.59kg less HSCW in high shedding lambs. Increased frequency of C. parvum and Giardia shedding in a specific animal (repeated detection) were associated with reduced HSCW and dressing%. Concurrent Giardia and Cryptosporidium shedding pre-slaughter was associated with reduced dressing%. No statistically significant main effects for either WEC (P>0.05) or Haemonchus status (P>0.05) were identified for any of the sheep meat productivity measures (live weight, HSCW and dressing%). The findings suggest naturally acquired Cryptosporidium and Giardia infections in grazing sheep are associated with depressed growth, carcase weight and dressing efficiency beyond the neonatal period in sheep representing a range of genetic backgrounds and different sheep production environments. PMID- 27692330 TI - A growing degree-day model for determination of Fasciola hepatica infection risk in New Zealand with future predictions using climate change models. AB - Infections of ruminants with Fasciola hepatica are considered to be of regional importance within New Zealand but there is very little recent information on its prevalence or severity other than anecdotal reports. Generally they are considered to be of secondary importance compared to gastrointestinal nematode infections. Utilizing data from Virtual Climate Stations (n=11491) distributed on a 5km grid around New Zealand a growing degree-day model was used to describe the risk of infection with liver fluke from 1972 to 2012 and then to apply the predictions to estimate the risk of fluke infections within New Zealand for the years 2040 and 2090. The growing degree-day model was validated against the most recent survey of infection within New Zealand in 1984. A strong positive linear relationship for 1984 between F. hepatica prevalence in lambs and infection risk (p<0.001; R2=0.71) was found indicating the model was effective for New Zealand. A linear regression for risk values from 14 regions in New Zealand for 1972-2012 did not show any discernible change in risk of infection over this time period (p>0.05). Post-hoc comparisons indicate the risk in Westland was found to be substantially higher (p<0.05) than all other regions with Northland ranked second highest. Notable predicted changes in F. hepatica infection risk in 2040 and 2090 were detected although they did vary between different climate change scenarios. The highest average percentage changes in infection risk were found in regions with low initial risk values such as Canterbury and Otago; in these regions 2090 infection risk is expected to rise by an average of 186% and 184%, respectively. Despite the already high levels of infection risk in Westland, values are expected to rise by a further 76% by 2090. The model does show some areas with little change with Taranaki predicted to experience only very minor increases in infection risk with average 2040 and 2090 predicted changes of 0% and 29%, respectively. Overall, these results suggest the significance of F. hepatica in New Zealand farming systems is probably underestimated and that this risk will generally increase with global warming following climate change. PMID- 27692331 TI - First study about the development of adult Echinococcus canadensis G6 genotype of goat origin in experimentally infected dogs. AB - Echinococcus granulosus sensu lato (E. granulosus sl) must be considered as a species complex, comprising Echinococcus granulosus sensu stricto (E. granulosus ss, genotypes G1-G3), Echinococcus equinus (G4), Echinococcus ortleppi (G5) and Echinococcus canadensis (G6-G10) although the species status of E. canadensis is still controversial. These genotypes closely match the intermediate hosts associated strains described in earlier times among which E. canadensis G6 corresponds to the camel strain. As there are no studies concerning the development of adult stages of the G6 genotype from non-camel origin, the aims of the present study were: to characterize for the first time the development of E. canadensis G6 in dogs experimentally infected with protoscoleces derived from goats, to describe the resultant adult morphology, to evaluate the growth of their rostellar hooks from larval to adult stages and to determine the prepatent period of the strobilar stage of E. canadensis G6 derived from goats. The development of the strobilar stage of E. canadensis G6 genotype of goat origin was examined by studying the growth (variation of the total worm length) and segmentation in experimentally infected dogs at 14, 25, 35 and 56days post infection. A morphological characterization of 35-day-old worms as well as of larval and adult rostellar hooks was also carried out by conventional optical microscopic observations and/or by scanning electron microscopy. The prepatent period of the strobilar stage was assessed by microscopic examination of faeces from 2 infected dogs. Our results were compared with published data from the camel and other strains. The roles of the host, genotype and species in morphological and developmental features as well as the taxonomic position of E. canadensis G6 were discussed. The prepatent period of E. canadensis G6 genotype of goat origin was determined as at least, 41days. The obtained results contribute to increase the knowledge about the biology and genetics of E. granulosus sl complex and are also of practical usefulness for the design of disease control strategies. PMID- 27692332 TI - Acaricidal efficacies of Lippia gracilis essential oil and its phytochemicals against organophosphate-resistant and susceptible strains of Rhipicephalus (Boophilus) microplus. AB - Plant-derived natural products can serve as an alternative to synthetic compounds for control of ticks of veterinary and medical importance. Lippia gracilis is an aromatic plant that produces essential oil with high content of carvacrol and thymol monoterpenes. These monoterpenes have high acaricidal activity against Rhipicephalus (Boophilus) microplus. However, there are no studies that show efficacy differences of essential oils between susceptible and organophosphate resistant strains of R. (B.) microplus. The aim of the present study was to compare acaricidal effects of essential oils extracted from two different genotypes of L. gracilis and the main monoterpenes on larvae of both susceptible and organophosphate resistant R. (B.) microplus larvae. The efficacy of the essential oil of two genotypes of L. gracilis (106 and 201) and their monoterpenes carvacrol and thymol was measured using the larval immersion test on coumaphos-resistant and susceptible strains of R. (B.) microplus. Lethal concentrations were calculated using GraphPad Prism 6.0. Chemical analysis was performed by GC-MS and FID. Thymol and carvacrol were observed to be major constituents in 106 and 201L. gracilis genotype essential oils, respectively. Essential oils of both genotypes were more effective against organophosphate resistant tick strain than susceptible tick strain. Carvacrol was 3.2 times more toxic to organophosphate resistant strain than to susceptible strain. Thymol was equally toxic to resistant and susceptible tick strains. The significantly higher efficacy monoterpene carvacrol against resistant ticks may lead to development of new natural product acaricide formulations for use to control organophosphate resistant R. (B.) microplus populations. PMID- 27692334 TI - Erratum to "Prevalence and molecular characterization of Cryptosporidium spp. and Giardia duodenalis in dairy cattle in Beijing, China" [Vet. Parasitol. 219 (2015) 61-65]. PMID- 27692333 TI - First detection of Leishmania kDNA in canine cerumen samples by qPCR. AB - Nowadays, searching for alternative non-invasive methods for molecular diagnosis of canine visceral leishmaniosis is getting increasingly important. We previously described the presence of Leishmania kinetoplast DNA (kDNA) in canine hair; in this case we hypothesized whether foreign DNA might be present in cerumen of dogs with leishmaniosis, and be detected by Real time quantitative PCR (qPCR). A population of 38 dogs that lived in Leishmania endemic areas was divided in two groups: A (33 dogs with confirmed leishmaniosis by serological techniques) and B (5 healthy dogs). Blood, lymph node, bone marrow and cerumen samples from all animals were tested for the presence of parasite kDNA. Our method was 100% specific, and in dogs from group A, Leishmania infantum kDNA was detected and quantified in the 100% of lymph node samples, in 90.9% of cerumen samples, in 88.5% of the bone marrow samples and in 57.6% of the blood samples. The qPCR cerumen is a new non-invasive method that shows a high potential for the diagnosis of zoonotic visceral leishmaniosis. PMID- 27692335 TI - Thymus vulgaris L. essential oil and its main component thymol: Anthelmintic effects against Haemonchus contortus from sheep. AB - Haemonchus contortus is an important gastrointestinal parasite on sheep farms in tropical regions. The resistance of the parasite against most anthelmintic drugs represents a great economic problem to sheep farming and is a major challenge that needs to be overcome. The searches for new anthelmintic agents that act on different stages of the parasite's life cycle are necessary for the development of new therapeutic options. The aim of this study was to evaluate the in vitro and in vivo anthelmintic activity of Thymus vulgaris essential oil against H. contortus and of its main component, the monoterpene thymol. Despite the relative ineffectiveness of the oil in the in vivo test, which may be corrected in the future after technical improvements to increase the oil's bioavailability, the in vitro results validated the popular use of T. vulgaris oil as an anthelmintic agent, at least against H. contortus. In fact, both the essential oil and thymol, which accounts for 50.22% of the oil composition, were effective against the three main stages of H. contortus. The oil and thymol were able to inhibit egg hatching by 96.4-100%, larval development by 90.8-100%, and larval motility by 97 100%. Similar to the positive control (levamisole 20mg/mL), the oil and thymol completely inhibited the motility of H. contortus adults within the first 8h of the experiment. Since thymol reproduces the anthelmintic effects of the oil and because it is the main component of the oil, it is reasonable to assume that thymol is the most important compound responsible for the anthelmintic effect of T. vulgaris. These results are of ethnopharmacological importance and may contribute to the development of new drugs and even herbal medicines, increasing treatment options for the farm breeding. PMID- 27692336 TI - Ticks threatening lineage of Anatolian wild sheep (Ovis gmelinii anatolica) and determination of their tick-borne pathogens. AB - We aimed to determine the ticks of the Anatolian wild sheep and to define their tick-borne pathogens while molecularly studying their relationships with those of the domestic sheep. Furthermore, another aim of this study is to investigate tick paralysis resulting in the death of the Anatolian wild sheep. Ticks and blood samples were collected from the wild sheep whilst tick samples were also collected from hares, guinea fowls, chickens, and a turkey living in the Anatolian wild sheep breeding area. While PCR amplification was carried out for the detection of Babesia spp., Theileria spp. and Anaplasma spp. in blood samples, CCHF virus was screened in the tick samples in addition to the above mentioned pathogens. Theileria spp. was detected in blood samples of 45 wild sheep. A total of 3494 ticks were collected from 52 Anatolian wild sheep, 5 hares, 5 guinea fowls, 2 chickens, and 1 turkey whereas 98 ticks were collected from the ground. B. ovis and T. ovis were detected in tick pools (Rh. bursa and H. excavatum) that were collected from the wild sheep. The paralysis was diagnosed in both of the hind legs of the newborn lambs infested with a great number of ticks. We also report that the tick species (H. excavatum and Rh. bursa) are determined to cause tick paralysis and tick toxicosis, which are associated with mortality especially in lambs. T. ovis and B. ovis were detected and studied for the first time in Anatolian wild sheep and in their ticks. The results of phylogenetic analyses showed that T. ovis and B. ovis isolates are genetically very close to the isolates that were previously obtained from the domestic small ruminants. We show that the Anatolian wild sheep can play the role of a reservoir for T. ovis. The presence of the CCHF virus has also been clearly shown and it has been observed that this virus, which is very pathogenic for humans, is anywise circulating in the region. PMID- 27692337 TI - The usefulness of direct agglutination test, enzyme-linked immunosorbent assay and polymerase chain reaction for the detection of Toxoplasma gondii in wild animals. AB - The aim of the study was to compare the usefulness of two antibody-based methods, the direct agglutination test (DAT) and enzyme linked immuosorbent assay (ELISA), with that of the polymerase chain reaction (PCR) for detecting anti-Toxoplasma gondii in samples derived from naturally-infected wild animals. Antibodies against T. gondii were detected in meat juice samples collected from 129 free- living carnivores and omnivores. T. gondii seroprevalence was confirmed in 73,6% of examined samples when DAT and ELISA were used separately, but in only 88,4% samples when both immunological tests were used in parallel. PCR results confirmed the presence of DNA of the parasite in 24 of all the 129 samples. Sixteen samples were classified as positive when all three tests were used. A moderate degree of agreement was found between DAT and ELISA (kappa=0.55). However, no agreement was found between the molecular and serological tests: kappa=-1.75 for DAT versus PCR; kappa=-1.67 ELISA versus PCR. By using both serological tests, antibodies against T. gondii were found in 77.5% of red foxes, 12.5% of badgers, 40% of martens and 8.3% of raccoon dogs. Antibodies against the parasite were detected also in one mink, but not in the sample derived from a polecat. T.gondii DNA was found in the brain tissue of 20 red foxes, three badgers and one raccoon dog. Our studies confirm that ELISA and DAT are suitable and reliable techniques for T. gondii antibody detection in meat juice from wild animals when serum samples are unavailable. Positive results obtained by immunological tests do not always reflect that the host was infected by T. gondii. They indicate only a contact with parasite. PCR should be used to confirm te presence of DNA from T. gondii. PMID- 27692338 TI - Canine and ovine tick-borne pathogens in camels, Nigeria. AB - In April 2008, whole blood samples were collected from 36 dromedary camels in Sokoto, North-western Nigeria. Following PCR and reverse line blotting, twenty two samples (61%) resulted positive for Ehrlichia/Anaplasma spp. and three (8%) for Theileria/Babesia spp., with three (8%) cases of co-infections being found. Both sequence and BLAST analyses identified Ehrlichia/Anaplasma spp. and Theileria/Babesia spp. positive cases as Anaplasma platys and Theileria ovis, respectively. This is the first report of the detection of A. platys and T. ovis in camels from sub-Saharan Africa. The epidemiological relevance of this finding is enhanced by the close living of these animals with both dogs and small ruminants. The high prevalence detected for A. platys suggests a possible role of camels as carriers of this infection. PMID- 27692339 TI - The white-nosed coati (Nasua narica) is a naturally susceptible definitive host for the zoonotic nematode Angiostrongylus costaricensis in Costa Rica. AB - Angiostrongylus costaricensis (Strongylida, Angiostrongylidae) is a roundworm of rodents, which may cause a severe or fatal zoonosis in several countries of the Americas. A single report indicated that the white-nosed coati (Nasua narica), acts as a potential free-ranging wildlife reservoir. Here we investigated the prevalence and features of A. costaricensis infection in two procyonid species, the white-nosed coati and the raccoon (Procyon lotor) from Costa Rica to better understand their possible role in the epidemiology of this zoonotic infection. Eighteen of 32 (56.2%) white-nosed coatis collected between July 2010 and March 2016 were infected with A. costaricensis but none of 97 raccoons from the same localities were diagnosed with this infection. First-stage larvae of A. costaricensis were obtained from feces of 17 fresh white-nosed coati carcasses by Baermann technique. Parasite identity was confirmed by morphology, histology and molecular characterization of target genes. These data demonstrate that the white nosed coati is a naturally susceptible definitive host for A. costaricensis in Costa Rica contrary to findings in the raccoon. PMID- 27692340 TI - In vitro study of anti-coccidial activity of essential oils from indigenous plants against Eimeria tenella. AB - This study was designed to evaluate the in vitro anticoccidial properties against Eimeria tenella of different essential oils and their major active components. Efficacy of ten essential oils from different Thai indigenous plants were preliminarily screened and only those with potential were further tested for effective concentrations and identifying their active compounds. Oocysticidal property was evaluated in term of sporulation inhibition of oocysts and the percentage of unsporulated, sporulated and degenerated oocysts, after treatment with 125MUg/ml of the selected essential oil, the sample was enumerated by haemocytometer, while coccidiocidal activity was assessed by the inhibition of sporozoite invasion in MDBK cell lines. Results showed that only Boesenbergia pandurata and Ocimum basilicum essential oils had strong sporulation inhibition activity by providing a higher ratio of degenerated oocysts and their IC50 were 0.134 and 0.101mg/ml, respectively. GC-MS analysis of B. pandurata essential oil found trans-b-ocimene, camphor, 1,8-cineole, geraniol, camphene, methyl cinnamate, l-limonene and linalool as the major components, while methyl chavicol, alpha-bergamotene, 1,8-cineole and trans-beta-ocimene were the main compounds of O. basilicum essential oil. Methyl cinnamate and camphor were the active components of B. pandurata oil, whereas methyl chavicol was the active component of O. basilicum oil by exhibiting the oocysticidal effect against E. tenella with IC50 values of 0.008, 0.023 and 0.054mg/ml, respectively. Furthermore, B. pandurata and O. basilicum oils also showed a strong cytotoxic property against coccidia with more than 70% inhibition of sporozoite invasion in MDBK cell lines, and their IC50 were 0.004 and 0.004mg/ml, respectively. Methyl cinnamate as well as camphor from B. pandurata and methyl chavicol from O. basilicum were also effective with IC50 values of 0.029, 0.023, and 0.022mg/ml, respectively. PMID- 27692341 TI - Primary psoas abscess caused by group A streptococcus in a child: Case report with microbiologic findings. AB - Primary abscess of the iliopsoas muscle in children is uncommon, especially due to Streptococcus pyogenes (group A streptococcus: GAS), which causes a variety of diseases ranging from pharyngitis to invasive life-threatening infection. We present primary iliopsoas abscess in a nine-year-old boy presenting with fever, mild disturbance of consciousness, limp, and pain in the right loin. Magnetic resonance imaging and isolation of GAS from both blood and abscess samples led us to the confirmative diagnosis. The patient recovered after treatment comprising drainage and intravenous antibiotics. The CovRS system is one of the best characterized systems with two-component signal transduction in the GAS, and mutations in covRS induce overproduction of various virulence factors that play a crucial role in invasive GAS infection. RopB, also known as a GAS regulator, influences the expression of multiple regulatory networks to coregulate virulence factor expression in GAS. In the present case, sequence analysis revealed the isolated GAS as emm type 6 with alterations in covS, whereas the covR and ropB genes were intact. The covS alterations might have influenced the virulence of the strain causing this severe GAS infection. PMID- 27692342 TI - Per- and polyfluoroalkyl substances (PFASs) - New endocrine disruptors in polar bears (Ursus maritimus)? AB - Per- and polyfluoroalkyl substances (PFASs) are emerging in the Arctic and accumulate in brain tissues of East Greenland (EG) polar bears. In vitro studies have shown that PFASs might possess endocrine disrupting abilities and therefore the present study was conducted to investigate potential PFAS induced alterations in brain steroid concentrations. The concentrations of eleven steroid hormones were determined in eight brain regions from ten EG polar bears. Pregnenolone (PRE), the dominant progestagen, was found in mean concentrations of 5-47ng/g (ww) depending on brain region. PRE showed significantly (p<0.01) higher concentrations in female compared to male bears. Dehydroepiandrosterone (DHEA) found in mean concentrations 0.67-4.58ng/g (ww) was the androgen found in highest concentrations. Among the estrogens estrone (E1) showed mean concentrations of 0.90-2.21ng/g (ww) and was the most abundant. Remaining steroid hormones were generally present in concentrations below 2ng/g (ww). Steroid levels in brain tissue could not be explained by steroid levels in plasma. There was however a trend towards increasing estrogen levels in plasma resulting in increasing levels of androgens in brain tissue. Correlative analyses showed positive associations between PFASs and 17alpha-hydroxypregnenolone (OH-PRE) (e.g. perflouroalkyl sulfonates (?PFSA): p<0.01, r=0.39; perfluoroalkyl carboxylates (?PFCA): p<0.01, r=0.61) and PFCA and testosterone (TS) (?PFCA: p=0.03, r=0.30) across brain regions. Further when investigating correlative associations in specific brain regions significant positive correlations were found between ?PFCA and several steroid hormones in the occipital lobe. Correlative positive associations between PFCAs and steroids were especially observed for PRE, progesterone (PRO), OH-PRE, DHEA, androstenedione (AN) and testosterone (TS) (all p<=0.01, r>=0.7). The results from the present study generally indicate that an increase in PFASs concentration seems to concur with an increase in steroid hormones of EG polar bears. It is, however, not possible to determine whether alterations in brain steroid concentrations arise from interference with de novo steroid synthesis or via disruption of peripheral steroidogenic tissues mainly in gonads and feedback mechanisms. Steroids are important for brain plasticity and gender specific behavior as well as postnatal development and sexually dimorph brain function. The present work indicates an urgent need for a better mechanistic understanding of how PFASs may affect the endocrine system of polar bears and potentially other mammal species.

Take home messages from the French Society of Anesthesiology and Intensive Care (SFAR) monothematic one-day meeting. PMID- 27692345 TI - Is a pediatrician performed gray scale ultrasonography with power Doppler study safe and effective for triaging acute non-perforated appendicitis for conservative management? AB - PURPOSE: The purpose of this study was to examine whether acute non-perforated appendicitis (ANPA) can be safely triaged by a pediatrician for conservative management (CM) using gray-scale ultrasonography with power Doppler (GSPD). METHOD: Seventy five cases of ANPA assessed by a pediatrician with GSPD (2013 2015) were reviewed. GSPD grading for ANPA was: I: slightly irregular wall/normal blood flow; II: irregular wall/increased blood flow; III: irregular wall/decreased blood flow; and IV: absence of wall/blood flow. Grades I/II were managed conservatively with intravenous antibiotics then encouraged to book for interval appendectomy (IA). Grades III/IV were reviewed for emergency appendectomy (EA) by a pediatric surgeon. RESULTS: GSPD grading was I (n=26), II (n=36), III (n=9), and IV (n=4). EA was required for 5 cases, one grade III, and four grade IV cases. One grade IV case was treated conservatively after surgical review but EA was unavoidable. Of the remaining 70 cases discharged well after a mean of 5.7days hospitalization, 25/70 had IA with chronic inflammation on histology, 6/70 had recurrence of ANPA treated successfully by EA, and 39/70 remain asymptomatic at least 10months after declining IA. Overall, GSPD triaging with CM was cheaper than surgery. CONCLUSIONS: GSPD performed by pediatricians appears to be safe/effective for triaging ANPA. LEVEL OF EVIDENCE: Level III. PMID- 27692344 TI - Autophagy inhibition upregulates CD4+ tumor infiltrating lymphocyte expression via miR-155 regulation and TRAIL activation. AB - Chemoresistance is a major challenge in lung cancer treatment. Recent findings have revealed that autophagic mechanism contributes significantly to immunosuppressive related chemoresistance. For that reason, targeting autophagy related immunosuppression is an important approach to reverse tumor drug resistance. In this study, we report for the first time that autophagy inhibition triggers upregulation of CD4+, Foxp3+ tumor infiltrating lymphocytes in late metastatic lung cancer tissues. Furthermore, autophagy blockage induces chemosensitization to carboplatin, immune activation and cell cycle arrest. This induction correlated with reduction in expression of drug resistance genes MDR1, MRP1, ABCG2 and ABCC2 along with decreased expression of PD-L1 which is associated with severe dysfunction of tumor specific CD8+ T cells. Furthermore, experiments revealed that co-treatment of carboplatin and autophagy inhibitor chloroquine increased lung tissue infiltration by CD4+, FoxP3+ lymphocytes and antigen-specific immune activation. Subsequent ex vivo experiments showed the activation of carboplatin related TRAIL-dependent apoptosis through caspase 8 and a synergistic role of miR-155 in lung tissue infiltration by CD4+, and FoxP3+ lymphocytes. Overall, our results indicate that autophagy blockage increases lung cancer chemosensitivity to carboplatin, but also reveal that miR-155 functions as a novel immune system activator by promoting TILs infiltration. These results indicate that targeting of autophagy can prevent cancer related immunosuppression and elucidate immune cell infiltration in tumor microenvironment thus representing a potential therapeutic strategy to inhibit lung cancer progression and metastasis. PMID- 27692346 TI - The operative management of children with complex perianal Crohn's disease. AB - BACKGROUND/PURPOSE: Perianal Crohn's disease (PCD) can affect both quality of life and psychological wellbeing. A subset of pediatric patients with complex PCD require surgical intervention, although appropriate timing and treatment regimens remain unclear. This study aimed to describe a large pediatric cohort in a tertiary center to determine the range of surgical management in children with complex PCD. METHODS: A retrospective review of children requiring operative intervention for PCD over 13 years (2002-2014) was performed. PCD was divided into simple and complex based on the type of surgical procedure, and the two groups were compared. RESULTS: The 57 children were divided into two groups: the simple group (N=43) underwent abscess drainage +/- seton insertion alone, and the complex group (N=14) underwent loop ileostomy +/- more extensive surgery. In the complex group, females were more predominant (57% of complex vs 30% of simple), and the average age at diagnosis was lower. Anti-TNF therapy was utilized in 79.1% of simple and 100% of complex PCD. All 14 complex patients underwent a defunctioning ileostomy, with 7 requiring further operations (subtotal colectomy=4, proctocolectomy +/- anal sparing=5, plastic surgery reconstruction with perineal flap/graft=4). CONCLUSION: Complex PCD represents a small but challenging subset of patients in which major surgical intervention may be necessary to alleviate the symptoms of this debilitating condition. LEVEL OF EVIDENCE: retrospective case study with no control group - level IV. PMID- 27692347 TI - Don't forget the dose: Improving computed tomography dosing for pediatric appendicitis. AB - BACKGROUND: A pediatric computed tomography (CT) radiation dose reduction program was implemented throughout our children's associated hospital system in 2010. We hypothesized that the CT dose received for evaluation of appendicitis in children would be significantly higher among the 40 referral, nonmember hospitals (NMH) than the 9 member hospitals (MH). METHODS: Preoperative CTs of pediatric (<18years) appendectomy patients between April 2012 and April 2015 were reviewed. Size specific dose estimate (SSDE), an approximation of absorbed dose incorporating patient diameter, and Effective Dose (ED) were calculated for each scan. RESULTS: 1128 (65%) of 1736 appendectomy patients underwent preoperative CT. 936 patients seen at and 102 children evaluated at NMH had dosing and patient diameter data for analysis. SSDE and ED were significantly higher with greater variance at NMH across all ages (all p<0.05, Figure). NMH's SSDE and ED also exceeded reference levels. CONCLUSION: Radiation exposure in CT scans for evaluation of pediatric appendicitis is significantly higher and more variable in NMH. A proactive approach to reduce dose, in addition to frequency, of CT scans in pediatric patients is essential. LEVEL OF EVIDENCE: Level III. PMID- 27692348 TI - [Follow-up interventions after suicide attempt. What tools, what effects and how to assess them?] AB - After attempting suicide, 60 to 70% of patients are discharged from emergency departments and referred to outpatient treatment which entails psychosocial strategies, pharmacological strategies or a combination. The main objective of outpatient care consists in preventing recurrent suicidal behavior. Yet suicide attempters have been found to be very difficult to engage in treatment. Between 11% and 50% of attempters refuse outpatient treatment or drop out of outpatient therapy very quickly. In order to address this extremely serious issue, for the past 20 years monitoring or follow up interventions has been presented as a promising approach. Follow-up intervention is defined as a service that aims at both increased access to and engagement in care as well as to prevent suicide and related behaviors. This approach consists in "stay in contact" or "connectedness" protocols using phone calls or tele-assistance, sending letters, email or mobile phone messages and medical visits or nursing at home. From one study to another these tools have been used separately, associated to one another or reinforced by motivational interviewing or brief psychotherapy. To our knowledge, since 1993 16 controlled and randomized controlled studies assessed the effectiveness of diverse follow-up. Four studies assessing telephone follow up reported a significant decrease in suicide reattempt while one study evaluating a sending letters strategy reported positive results. Among five studies assessing engagement in healthcare, only two (one using phone follow up and the other sending letters reported significantly positive results. The refusal rate of monitoring strategies has not exceeded 11% attesting to the high applicability of these methods. Despite several positive results, we cannot draw firm conclusions on replicability of these results. This is largely due to methodological issues: lack of standardization of interventions, lack of consensus on definition of the main measured variables (recurrent suicidal behavior, engagement in healthcare) but also to the confounding effect of other care approaches frequently associated with follow up intervention services. Further studies and research should be conducted as follow-up intervention services are increasingly used in suicide prevention because of their good acceptability and usefulness. PMID- 27692349 TI - [Validation of a French translation of Krueger's personality inventory for DSM-5 in its brief form (PID-5 BF)]. AB - OBJECTIVE: Since the publication of the DSM-5 (APA, 2013), the dimensional conception of the personality disorders is co-existing with the classical categorical paradigm. Tools have been proposed for the evaluations of five big pathological factors to be explored further according to the APA (negative affectivity, detachment, antagonism, disinhibition, psychoticism). Despite numerous works using these questionnaires (30 works in 3 years according to Al Adjani et al., 2015), none of them have yet been translated into French. Also, the main objective of the paper is to present a French translation of the Personality Inventory for DSM -5 by Kruegger et al. (2013) in its brief form of 25 items (PID-5 BF). METHOD: To reach this goal, we have employed the classic translation-retranslation method (Vallerand, 1989) and tested the consistence and the validity of this French version among a non-clinical sample (n=216) of young adults (age=31.4, SD=4.8), in joining some other questionnaires in their short forms to study the external validity of the PID-5 about the psychological distress (SCL-10, Nguyen, 1983), the categorical diagnosis of personality disorders (SAPAS, Moran et al., 2003) and the classical Big Five dimensions of the personality (BDI 10, Ramamstedt and John, 2007). The internal consistency of this translation has been studied through the classical outcomes on factor analysis for the dimensional repartitions of the items in 5 scales and Cronbach's alpha for the consistency of each found dimensions. The external validity has been explored by studying Pearson's correlations between the outcomes on each dimension of the PID-5 BF and both the clinical dimensions of SCL-10, personality dimensions of the BFI-10 or personality disorders (SAPAS). RESULTS: Factor analysis led to the same repartition of the 25 items as the original versions. Each of the dimensions is consistent enough (alpha>.65) to be taken into account as clinically significant. The items of the French version of the PID-5 BF follow the expected repartitions in 5 dimensions, which are consistent enough. Although their mean scores are significantly not different from the outcomes found by Krueger with the PID-5 200 items among another non-clinical population (n=264), one cannot say that is enough to ensure the external validity of our translation, for it uses neither the same tools nor sample. A comparison with a French translation of the PID-5 would be more significant. However, the external validity of the French version seems to be significant enough. Global score on the PID-5 is correlated both to the Global Severity Index of the SCL-10, which reflects global psychological distress, and SAPAS's score, which evaluates the suspicion of personality disorder. The clinical validity of the PID-5 is confirmed by the relationships between negative affectivity and anxiety or depression or antagonism and hostility, although the clinical scale of the SCL 10, with one item by dimension, is less sensitive than the complete original version in 90 items (DeRogatis, 1974). PID-5 score and domains are also correlated with the Big Five personality dimension and global score of personality disorders which led us to think that it is coherent with the evaluation of personality suffering (r=.34) and dimensions. The links between negative affectivity and neurosism (r=.48) or between desinhibition and extraversion (r=.32) or the negative correlation between psychoticism and conscientiousness (r=-0.16) are consistent with the expectations related both to the descriptions of the domains by the DSM and outcomes on the comparisons between PID-5 200 item scales and NEO-PI or BFI 45 items. DISCUSSION: This translation offers enough consistency and validity to be used in future studies. This could lead us to either continue studying a more representative general population or testing its validity in focusing on a clinical sample where personality disorders are prevalent, such as homeless men or substance users. As soon as a French version of the PID-5 200 items is published, one can compare the outcomes on PID-5 BF and PID-5 to lead to estimations of personality disorders and pathological domains among French populations and explore personality disorders throughout a dimensional paradigm instead of syndromic perspective. One can also see whether the items that have been kept for each dimension are as saturated in the French version as in the original one. Among general populations, comparisons with clinical distress, syndromic personality disorders or dimensional aspect of personality could be done with complete versions of PID 5, Symptom Check-list, Personality Disorders Questionnaires or Big Five Inventory; therefore, the brief forms of any questionnaire could be used among any people whose psychological distress or side effects impaired their attention and concentration.

AB - BACKGROUND: The etiology of autism spectrum disorders (ASD) is complex and multifactorial, and the roles of genetic and environmental factors in its emergence have been well documented. Current research tends to indicate that these two factors act in a synergistic manner. The processes underlying this interaction are still poorly known, but epigenetic modifications could be the mediator in the gene/environment interface. The epigenetic mechanisms have been implicated in susceptibility to stress and also in the pathogenesis of psychiatric disorders including depression and schizophrenia. Currently, several studies focus on the consideration of the etiological role of epigenetic regulation in ASD. OBJECT: The object of this review is to present a summary of current knowledge of an epigenetic hypothesis in ASD, outlining the recent findings in this field. METHODS: Using Pubmed, we did a systematic review of the literature researching words such as: autism spectrum disorders, epigenetics, DNA methylation and histone modification. RESULTS: Epigenetic refers to the molecular process modulating gene expression without changes in the DNA sequence. The most studied epigenetic mechanisms are those that alter the chromatin structure including DNA methylation of cytosine residues in CpG dinucleotides and post translational histone modifications. In ASD several arguments support the epigenetic hypothesis. In fact, there is a frequent association between ASD and genetic diseases whose epigenetic etiologies are recognized. A disturbance in the expression of genes involved in the epigenetic regulation has also been described in this disorder. Some studies have demonstrated changes in the DNA methylation of several autism candidate genes including the gene encoding the oxytocin receptor (OXTR), the RELN and the SHANK3 genes. Beyond the analysis of candidate genes, recent epigenome-wide association studies have investigated the methylation level of several other genes and showed hypomethylation of the whole DNA in brain and blood samples of autistic patients. The changes in epigenetic marks following exposure to environmental factors known as autism risk factors are also discussed in many reports. They include nutritional (vitamin D and folate) and toxic (sodium valproate, bisphenol A) factors. Despite a considerable contribution to understanding the complexity of ASD etiology, the epigenetic studies suffer from numerous methodological biases that limit the scope of their results and make their interpretation difficult. The cell samples used in the psychiatric studies are mostly from the post-mortem tissue of the central nervous system, and factors that might change the epigenome (age, gender, treatments received...) are not taken into account. The use of blood and buccal epithelium samples raises in turn the question as to whether the epigenome of these cells reflects that of the nerve cells. DNA methylation can also be influenced by cell subcomposition variability, transcriptional variability and by DNA sequence variants. CONCLUSION: These recent discoveries in epigenetics are the beginnings of an etiopathogenic research revolution in neurodevelopmental disorders. The conceptualization of epigenetic processes is in its early stages and despite its limited means will help integrate disparate data factors previously involved in autism. It could also be the target for the development of new therapeutic modalities. PMID- 27692352 TI - Editors' Note. PMID- 27692351 TI - Azithromycin assay in drug formulations: Validation of a HPTLC method with a quadratic polynomial calibration model using the accuracy profile approach. AB - Many different assaying high performance thin layer chromatography (HPTLC) methods have been developed and validated in order to be used in routine analysis in different analytical fields. Validation often starts by the evaluation of the linearity of the calibration curve. Frequently, if the correlation coefficient is close to one, the linear calibration curve model is considered to be proper to predict the unknown concentration in the sample. But is this simple model effective to assess the behavior of the response of an HPTLC method as a function of concentration. To answer this question, a method for the determination of azithromycin by HPTLC has been developed and validated following both the classical approach and that based on the accuracy profile. Silica gel plates with fluorescence indicator F254 and chloroform - ethanol - 25% ammonia 6:14:0.2 (v/v/v) as mobile phase were used. Analysis was carried out in reflectance mode at 483nm. The RF of azithromycin was 0.53. The validation based on the classical approach, shows that the behavior is not linear, even though r2=0.999 because the lack of fit test is significant (P<0.05). Validation based on the accuracy profile approach considering both the straight line and the quadratic regression model, show that the former results is a beta-expectation tolerance interval outside the acceptance limits, while with the latter, this interval is within the limits of +/-5% acceptability for a range which extends from 0.2 to 1.0MUg/zone. With the quadratic model, the method showed to be precise and accurate. PMID- 27692353 TI - Does Donor Status, Race, and Biological Sex Predict Organ Donor Registration Barriers? AB - PURPOSE: The purpose of the current study was to examine differences among bodily integrity, disgust, medical mistrust, and superstition among African Americans, Caucasians, and Latinos; females and males; and registered organ donors and non registered potential donors. METHODS: A random digit dialing phone survey was utilized to garner information pertaining to organ donation beliefs among African American (n = 200), Caucasian (n = 200), and Latino (n = 200) Chicago residents. More specifically, participants responded to measures of bodily integrity, disgust, medical mistrust, and superstition, organ donor registration status, among others. RESULTS: The results indicated that African American and Latino participants were less likely to be registered organ donors than Caucasians (p < .001). In general, females maintained fewer barriers than males with respect to bodily integrity (p < .05), disgust (p = .01), and superstition (p = .01). With respect to organ donation barriers, bodily integrity (p < .0001) emerged as a central concern among those surveyed. CONCLUSION: This study highlights the significance of audience segmentation when promoting posthumous organ and tissue donation. Specifically, the results stress the importance of constructing distinct messages to non-registered potential donors compared to messages delivered to registered donors. Moreover, different barriers surfaced among females and males as well as among African American, Caucasian, and Latino residents. It is clear that a one size fits all approach will likely not work when promoting organ and tissue donation. PMID- 27692354 TI - Recruitment of Underrepresented Minorities in Medical School Through a Student led Initiative. AB - The goal of matriculating a diverse medical cohort remains important for institutions across the country as it results in an increase in the diversity of the physician workforce. By admitting students who are underrepresented in medicine, the pressing health needs of the growing and diverse patient population of our country can be met by physicians who are representative of their communities. Given the challenges of choosing from a small pool of applicants, medical schools should consider seeking the support of current medical students in expanding the applicant pool and recruiting the next generation of physicians. The purpose of this paper is to describe a student-led initiative established at the University of Kentucky College of Medicine for recruiting students underrepresented in medicine. Through this pipeline program, current underrepresented applicants experience a two-day recruitment event that introduces them to life as a medical student. Incorporating current medical students in recruitment programming allows institutions to access a knowledgeable and inspirational resource that is readily available. Current medical students can provide firsthand perspectives into the journey that is medical school while serving as role models for future physicians. PMID- 27692355 TI - Mini-Medical School Programs' Influence on Students' Desire to Pursue Medicine. AB - PURPOSE: Mini-Medical school programs have become an increasingly popular means of encouraging high-school students to consider medical professions. However, there is little research evaluating the long-term effect of these programs on influencing career choice. The purpose of our study was to determine the motivational factors for attending the Mini-Medical school programs at our institution, student satisfaction with their experience, and whether it impacts intended secondary education and career choices. METHODS: An online anonymous survey was distributed to Drexel University College of Medicine Mini-Medical school program graduates to determine factors influencing student participation and program satisfaction. RESULTS: The most influential factors in attending the program were to confirm an interest in medicine (n = 55, 95%) and parental advice (n = 29, 50%). Most maintained an interest in medicine: 57% (n = 33) pursued a pre-med degree, 55% (n = 32) planned to apply to medical school within 3 years; and 12% (n = 7) were either in medical school or matriculating in the fall of 2015. 91% (n = 53) participants noted the program's influence on choosing a pre med undergraduate track. CONCLUSION: Our results suggest Mini-Medical school programs significantly impacted students' decision to pursue a medical career through fostering interest and effectively answering students' questions about the field. PMID- 27692356 TI - Childhood Obesity in an Inner-City Primary Care Population: A Longitudinal Study. AB - BACKGROUND: Understanding the dynamics of obesity among children and adolescents in high-risk, low-income patient populations is critical to guide and evaluate appropriate clinical and public health interventions. METHODS: We identified a cohort of 472 predominantly low-income, minority pediatric patients aged 3-18 years with baseline measurements in 2010 and analyzed follow-up data through September 2013. Weight status at baseline and end of follow-up were ascertained. RESULTS: The prevalence of obesity was 25% (95% confidence interval [CI] 21%-29%) at baseline and 24% (95% CI 20%-28%) after an average of 2.3 years follow-up. Among the 353 subjects who were not obese at baseline, the cumulative incidence of obesity was 8% (95% CI 5%-11%). Those who were normal weight at baseline had an incidence of 3% (1%-6%); those who were overweight had an incidence of 22% (95% CI 14%-32%). Among the 119 subjects who were obese at baseline, 29% (95% CI 21%-38%) were not obese at the end of follow-up. Remission of obesity among those who were severely obese was only 12% (95% CI 4%-26%); among other obese patients remission was 38% (95% CI 28%-50%). CONCLUSION: The prevalence of obesity did not change substantially during follow-up. The cumulative incidence of obesity was 8%, and most of the incidence was among children who were overweight at baseline. Remission was common, especially among those who were not severely obese at baseline. Understanding and addressing determinants of obesity over the lifecourse is critical to the long-term health of children in the United States. PMID- 27692357 TI - Correlation of CAT Score With Peak Expiratory Flow in Acute Exacerbation of COPD Patients. AB - INTRODUCTION: Chronic obstructive pulmonary disease (COPD) leads to physical activity limitation and a significant reduction in quality of life. This study aimed to investigate the correlation between The COPD Assessment Test (CAT) score and peak expiratory flow (PEF), and the factors effecting hospital admission rates of patients with COPD. METHODS: This observational study was conducted prospectively. CAT score was calculated and PEF measured at the time of emergency department admission. Descriptive statistics were expressed as number (n), percentage (%), and mean +/- standard deviation. Chi-Square and correlation tests were used for statistical analyses. A p value of less than 0.05 was considered statistically significant. RESULTS: Of 123 patients included in the study, 85 (69.1%) were male and 38 (30.9%) were female. Pulse pressure, pH, blood urea nitrogen, oxygen saturation measured by pulse oximetry (SpO2), PO2, PCO2, and SpO2 values on arterial blood gas analysis, and PEF value were significantly correlated to CAT score (p < 0.05). CONCLUSION: High CAT score and low PEF value can be used to make the decision of hospitalization from emergency department in acute exacerbations of COPD. PMID- 27692358 TI - Stiff Person Syndrome Masquerading as Acute Coronary Syndrome. AB - Stiff person syndrome (SPS) is a rare neuroimmunological disorder characterized by severe progressive muscle stiffness in axial and lower extremity musculature with superimposed painful muscle spasms. Although chest pain is a common reason for SPS patients presenting to the emergency room, this disorder is overlooked and not part of the differential diagnosis of chest pain. Herein, we report on a middle age male presenting with classic symptoms of SPS; however, due to the rarity of this disease, he was initially thought to have acute coronary syndrome. Clinicians should consider the diagnosis of SPS in patients with fluctuating muscle spasms in the torso and/or extremities in the setting of repeated hospitalizations without subsequent symptom relief. PMID- 27692359 TI - Surgical Residency Training in Developing Countries: West African College of Surgeons as a Case Study. AB - BACKGROUND: In 1904, William Halsted introduced the present model of surgical residency program which has been adopted worldwide. In some developing countries, where surgical residency training programs are new, some colleges have introduced innovations to the Halsted's original concept of surgical residency training. These include 1) primary examination, 2) rural surgical posting, and 3) submission of dissertation for final certification. STUDY DESIGN: Our information was gathered from the publications on West African College of Surgeons' (WACS) curriculum of the medical schools, faculty papers of medical schools, and findings from committees of medical schools. Verbal information was also gathered via interviews from members of the WACS. Additionally, our personal experience as members and examiners of the college are included herein. We then noted the differences between surgical residency training programs in the developed countries and that of developing countries. RESULTS: The innovations introduced into the residency training programs in the developing countries are mainly due to the emphasis placed on paper qualifications and degrees instead of performance. CONCLUSION: We conclude that the innovations introduced into surgical residency training programs in developing countries are the result of the misconception of what surgical residency training programs entail.

Information is presented on the prevalence of endometritis in the past and at present. The review describes uterine sampling techniques for mares: swabbing, cytobrushing, low volume lavage and biopsy. The performance of culture, cytology and histology and threshold values is discussed. Correlations between different diagnostic methods and fertility are presented, as well as specificities, sensitivities and positive and negative predictive values of the diagnostic methods. The necessity for double-guarded techniques is emphasized to prevent sample contamination. PMID- 27692362 TI - HIF1A and EPAS1 mRNA and protein expression during in vitro culture of human primary term cytotrophoblasts and effect of oxygen tension on their expression. AB - During the first trimester of pregnancy, placenta formation probably occurs in a low-oxygen environment necessary to protect cytotrophoblasts from oxidative stress and to allow proper gene regulation. Transcription factors involved in gene regulation under low oxygen tension are the hypoxia-inducible factors, mainly HIF1A, EPAS1 and their dimerization partner HIF1B. Little is known about their expression during in vitro culture of cytotrophoblasts under chronic hypoxia. We assessed HIF1A and EPAS1 expression in a 4-day in vitro culture of primary term cytotrophoblasts under 21% O2 and 2.5% O2. Copy numbers and relative mRNA expression were assessed by real-time quantitative polymerase chain reaction. Protein levels were quantified by immunoblot and densitometric analysis. In undifferentiated cytotrophoblasts, EPAS1 transcripts were four times more abundant than HIF1A transcripts (2.14e7 and 5e6copies/MUg total RNA, respectively). During cell culture, HIF1A mRNA expression increased after 24h and then decreased to stay stable. The expression was even lower when cells were grown under 2.5% O2. EPAS1 mRNA expression increased during cytotrophoblast differentiation. The expression was higher when cells were under 21% O2 than when they were under 2.5% O2. Interestingly, HIF1A, but not EPAS1, was detected in the nuclei of undifferentiated cytotrophoblasts, and in the nuclei of cytotrophoblasts that grew under 21% O2. During cytotrophoblast differentiation, no variation in HIF1A protein levels was detected. To the contrary, EPAS1 protein level increased during differentiation, and oxygen tension had no effect on EPAS1 protein level. In conclusion, HIF1A and EPAS1 expression was not inhibited by chronic hypoxia during in vitro cytotrophoblast differentiation. PMID- 27692363 TI - Exogenous melatonin reduced blood pressure in late-term ovine fetus via MT1/MT2 receptor pathways. AB - Melatonin is involved in the regulation of blood pressure through the receptor dependent or independent route. However, the effect of melatonin on fetal blood pressure is unknown. This study investigated the effect of melatonin on blood pressure of the late-term ovine fetus in utero. Melatonin and/or antagonists were intravenously administered into the fetuses. Mean arterial pressure and heart rate were recorded. Fetal blood samples were analyzed for biochemical parameters and hormones, including cortisol, angiotensin I, angiotensin II, aldosterone, atrial natriuretic peptide, corticotrophin-releasing hormone, adrenocorticotropic hormone, and endothelin. Fetal blood pressure was decreased following administration of melatonin, whereas it was increased following administration of luzindole, but not prazosin. Plasma level of endothelin was decreased by melatonin, which was blocked by luzindole. Our study suggested that melatonin reduced fetal blood pressure via MT1/MT2 receptors and possibly involving release of endothelin. PMID- 27692364 TI - PLAC1 is involved in human trophoblast syncytialization. AB - Placenta specific protein 1 (PLAC1) is thought to be important for murine and human placentation because of its abundant expression in placenta; however, the trophoblast subtypes that express PLAC1 at the fetomaternal interface and the major role of PLAC1 in placentation are still unclear. This study investigated the expression pattern of PLAC1 at the human fetomaternal interface and its involvement in trophoblast syncytialization. Localization of PLAC1 at the fetomaternal interface was studied using in situ hybridization (ISH) and immunohistochemistry (IHC) assays. Real time RT-PCR and Western Blot were employed to exhibit the expression pattern of PLAC1 during human spontaneous syncytialization of term primary cytotrophoblast cells (CTBs). Spontaneous syncytialization of a primary term CTBs model transfected with siRNA specific to PLAC1 was used to investigate the role of PLAC1 during human trophoblast syncytialization. The results showed that PLAC1 was mainly expressed in the human villous syncytiotrophoblast (STB) layer throughout gestation, and the expression level of PLAC1 was significantly elevated during human trophoblast syncytialization. Down-regulation of PLAC1 via specific PLAC1 siRNA transfection attenuated spontaneous syncytialization of primary term CTBs (p<0.05) as indicated by cell fusion index and the expression patterns of the corresponding markers. These data demonstrate the facilitative role of PLAC1 in normal human trophoblast syncytialization. PMID- 27692366 TI - Effects of Spin-Labels on Membrane Burial Depth of MARCKS-ED Residues. AB - Site-directed spin-labeling electron paramagnetic resonance spectroscopy is a useful tool to obtain information about the environment of specific residues. One of its applications is to investigate membrane protein topology based on the accessibility of the spin label, with the assumption that the position of the spin label in the membrane is close to that of the native residue. This assumption is valid in proteins with well-ordered structures, but could be problematic in small peptides because the labeling may cause a perturbation that is large enough to change local interactions between the peptide and the membrane. To quantitatively characterize such effects, we have simulated the association of a 25-amino-acid peptide, MARCKS-ED, to membranes with and without spin labels. Our simulations show that the depths of spin labels are ~6-17 A deeper than the unlabeled charged and polar residues in the wild-type. When the hydrophobic residue Phe is labeled, however, the spin-label depth is close to that of the native residue as well as the experimental value. Our study suggests that one should be cautious in interpretation of spin label data when charged and polar residues in small peptides are labeled. PMID- 27692365 TI - Contributions of Microtubule Dynamic Instability and Rotational Diffusion to Kinetochore Capture. AB - Microtubule dynamic instability allows search and capture of kinetochores during spindle formation, an important process for accurate chromosome segregation during cell division. Recent work has found that microtubule rotational diffusion about minus-end attachment points contributes to kinetochore capture in fission yeast, but the relative contributions of dynamic instability and rotational diffusion are not well understood. We have developed a biophysical model of kinetochore capture in small fission-yeast nuclei using hybrid Brownian dynamics/kinetic Monte Carlo simulation techniques. With this model, we have studied the importance of dynamic instability and microtubule rotational diffusion for kinetochore capture, both to the lateral surface of a microtubule and at or near its end. Over a range of biologically relevant parameters, microtubule rotational diffusion decreased capture time, but made a relatively small contribution compared to dynamic instability. At most, rotational diffusion reduced capture time by 25%. Our results suggest that while microtubule rotational diffusion can speed up kinetochore capture, it is unlikely to be the dominant physical mechanism for typical conditions in fission yeast. In addition, we found that when microtubules undergo dynamic instability, lateral captures predominate even in the absence of rotational diffusion. Counterintuitively, adding rotational diffusion to a dynamic microtubule increases the probability of end-on capture.

AB - Tension pneumocephalus is rare but has been well documented following trauma and neurosurgical procedures. It is a surgical emergency as it can lead to neurological deterioration, brainstem herniation and death. Unlike previous cases where tension pneumocephalus developed postoperatively, we describe a case of intraoperative tension pneumocephalus leading to sudden, massive open brain herniation out of the craniotomy site. The possible causative factors are outlined. It is imperative to rapidly identify possible causes of acute intraoperative brain herniation, including tension pneumocephalus, and institute appropriate measures to minimize neurological damage.

AB - : Neonates and small infants with craniofacial malformation may be very difficult or impossible to mask ventilate or intubate. We would like to report the fiberoptic intubation of a small infant with Treacher Collins Syndrome using the technique described by Ellis et al. CASE REPORT: An one month-old infant with Treacher Collins Syndrome was scheduled for mandibular surgery under general endotracheal anesthesia. Direct laryngoscopy for oral intubation failed to reveal the glottis. Fiberoptic intubation using nasal approach and using oral approach through a 1.5 size laryngeal mask airway were performed; however, both approach failed because the fiberscope loaded with a one 3.5mm ID uncuffed tube was stuck inside the nasal cavity or inside the laryngeal mask airway respectively. Therefore, the laryngeal mask airway was keep in place and the fiberoptic intubation technique described by Ellis et al. was planned: the tracheal tube with the 15mm adapter removed was loaded proximally over the fiberscope; the fiberscope was advanced under video-screen visualization into the trachea; the laryngeal mask airway was removed, leaving the fiberscope in place; the tracheal tube was passed completely through the laryngeal mask airway and advanced down over the fiberscope into the trachea; the fiberscope was removed and the 15mm adapter was reattached to the tracheal tube. CONCLUSION: The fiberoptic intubation method through a laryngeal mask airway described by Ellis et al. can be successfully used in small infants with Treacher Collins Syndrome. PMID- 27692369 TI - [Tension pneumothorax during peroral endoscopic myotomy for treatment of esophageal achalasia under general anesthesia]. AB - More and more endoscopically gastrointestinal procedures require anesthesiologists to perform general anesthesia, such as "peroral endoscopic myotomy". Peroral endoscopic myotomy is a novel invasive treatment for the primary motility disorder of esophagus, called esophageal achalasia. Despite of its minimally invasive feature, there are still complications during the procedure which develop to critical conditions and threat patients' lives. Herein we describe a case about tension pneumothorax subsequent to esophageal rupture during peroral endoscopic myotomy. The emergent management of the complication is stated in detail. The pivotal points of general anesthesia for patients undergoing peroral endoscopic myotomy are emphasized and discussed. Also, intraoperative and post-operative complications mentioned by literature are integrated. PMID- 27692371 TI - [Paratracheal cyst rupture: a differential diagnosis for tracheal rupture]. AB - Tracheobronchial rupture is a rare but potentially life-threatening complication commonly caused by neck and chest trauma. Iatrogenic tracheobronchial rupture can be caused by intubation, tracheostomy, bronchoscopy but also linked to pre existing primary diseases. Paratracheal air cysts, infrequently described in literature, seem to be associated with obstructive lung disease and weaknesses in right posterior lateral wall of the trachea. We report a case of a paratracheal air cyst rupture in a previous healthy patient. PMID- 27692370 TI - [Effect of dexmedetomidine on acute lung injury in experimental ischemia reperfusion model]. AB - PURPOSE: Ischemia-reperfusion injury is one of the consequences of tourniquet application for extremity surgery. The aim of the study was to establish the effect of dexmedetomidine on the acute lung injury following lower extremity experimental ischemia-reperfusion model in rats. METHODS: Twenty-eight Wistar Albino breed rats were recruited after Ethics Committee approval and allocated into 4 groups, each with 7 subjects. Group 1 (SHAM) received only anesthesia. Group 2 (IR) had experienced 3h of ischemia and 3h of reperfusion using left lower extremity tourniquet after anesthesia application. Groups 3 (D-50) and 4 (D 100) had undergone the same procedures as in the Group 2, except for receiving 50 and 100mg.kg-1, respectively, dexmedetomidine intraperitoneally 1h before the tourniquet release. Blood samples were obtained for the analysis of tumor necrosing factor-alpha and interleukin-6. Pulmonary tissue samples were obtained for histological analysis. RESULTS: No significant difference regarding blood tumor necrosing factor-alpha and interleukin-6 values was found among the groups, whereas pulmonary tissue injury scores revealed significant difference. Histological scores obtained from the Group 2 were significantly higher from those in the Groups 1, 3 and 4 with p-values 0.001 for each comparison. Moreover, Group 1 scores were found to be significantly lower than those in the Groups 3 and 4 with p-values 0.001 and 0.011, respectively. No significant difference was observed between the Groups 3 and 4. CONCLUSION: Dexmedetomidine is effective in reduction of the experimental ischemia-reperfusion induced pulmonary tissue injury in rats, formed by extremity tourniquet application. PMID- 27692372 TI - Determination of ultra-trace amounts of prosthesis-related metals in whole blood using volumetric absorptive micro-sampling and tandem ICP - Mass spectrometry. AB - This paper reports on an evaluation of the suitability of a novel sample collection approach, volumetric absorptive micro-sampling (VAMS), in the context of the determination of ultra-trace concentrations of prosthesis-related metals (Al, Ti, V, Co, Cr, Ni, Sr and Zr) in whole blood. In a first phase, a simple dilute-and-shoot approach (100-fold dilution) followed by tandem ICP - mass spectrometry (ICP-MS/MS) analysis was developed for the accurate and sensitive determination of the target elements. The ICP-MS/MS method relies on the use of mass shift reactions proceeding when pressurizing the collision/reaction cell (CRC) with CH3F/He for dealing with spectral overlap. Limits of detection (LoDs) between 0.3 and 30 ng L-1 were attained in a multi-element approach. The accuracy of the method was demonstrated via successful analysis of the reference materials Seronorm Whole Blood Levels 1 and 3, and real venous blood samples, spiked with the target elements at different concentration levels (5-50 MUg L-1). Although the implementation of VAMS devices introduced contamination problems for Al, Cr and Ni, VAMS followed by ICP-MS/MS analysis shows potential for future real-life routine applications when assessing levels of Ti, V, Co, Sr and/or Zr. PMID- 27692373 TI - A review of the determination of persistent organic pollutants for environmental forensics investigations. AB - The field of environmental forensics emerged in the 1980s as a consequence of legislative frameworks enacted to enable parties, either states or individuals, to seek compensation with regard to contamination or injury due to damage to the environment. This legal environment requires stringent record keeping and defendable data therefore analysis can sometimes be confined to data to be obtained from certified laboratories using a standard accredited analytical method. Many of these methods were developed to target specific compounds for risk assessment purposes and not for environmental forensics applications such as source identification or age dating which often require larger data sets. The determination of persistent organic pollutants (POPs) for environmental forensic applications requires methods that are selective but also cover a wide range of target analytes which can be identified and quantified without bias. POPs are used in a wide variety of applications such as flame retardants, fire suppressants, heat transfer agents, surfactants and pesticides mainly because of their chemical inertness and stability. They also include compounds such as dioxins that can be unintentionally produced from industrial activities. POPs are persistent in the environment, bioaccumulative and/or toxic and therefore require analytical methods that are sensitive enough to meet the low detection limits needed for the protection of the environment and human health. A variety of techniques, procedures and instruments can be used which are well suited for different scenarios. Optimised methods are important to ensure that analytes are quantitatively extracted, matrix coextractables and interferences are removed and instruments are used most effectively and efficiently. This can require deviation from standard methods which can open the data up to further scrutiny in the courtroom. However, when argued effectively and strict QA/QC procedures are followed the development and optimization of methods based on investigation specific scenarios has the potential to generate better quality and more useful data. PMID- 27692374 TI - Continuous and real-time bioaerosol monitoring by combined aerosol-to-hydrosol sampling and ATP bioluminescence assay. AB - We present a methodology for continuous and real-time bioaerosol monitoring wherein an aerosol-to-hydrosol sampler is integrated with a bioluminescence detector. Laboratory test was conducted by supplying an air flow with entrained test bacteria (Staphylococcus epidermidis) to the inlet of the sampler. High voltage was applied between the discharge electrode and the ground electrode of the sampler to generate air ions by corona discharge. The bacterial aerosols were charged by the air ions and sampled in a flowing liquid containing both a cell lysis buffer and adenosine triphosphate (ATP) bioluminescence reagents. While the liquid was delivered to the bioluminescence detector, sampled bacteria were dissolved by the cell lysis buffer and ATP was extracted. The ATP was reacted with the ATP bioluminescence reagents, causing light to be emitted. When the concentration of bacteria in the aerosols was varied, the ATP bioluminescence signal in relative light units (RLUs) closely tracked the concentration in particles per unit air volume (# cm-3), as measured by an aerosol particle sizer. The total response time required for aerosol sampling and ATP bioluminescence detection increased from 30 s to 2 min for decreasing liquid sampling flow rate from 800 to 200 MULPM, respectively. However, lower concentration of S. epidermidis aerosols was able to be detected with lower liquid sampling flow rate (1 RLU corresponded to 6.5 # cm-3 of S. epidermidis aerosols at 200 MULPM and 25.5 # cm-3 at 800 MULPM). After obtaining all data sets of concentration of S. epidermidis aerosols and concentration of S. epidermidis particles collected in the flowing liquid, it was found that with our bioluminescence detector, 1 RLU corresponded to 1.8 * 105 (+/-0.2 * 105) # mL-1 of S. epidermidis in liquid. After the lab-test with S. epidermidis, our bioaerosol monitoring device was located in the lobby of a building. Air sampling was conducted continuously for 90 min (air flow rate of 8 LPM, liquid flow rate of 200 MULPM) and the ATP bioluminescence signal of indoor bioaerosols was displayed with time. Air sampling was also carried out using the 6th stage of Andersen impactor in which a nutrient agar plate was used for the impaction plate. The sample was cultured at 37 degrees C for five days for colony counting. As a result, it was found that the variation of the bioluminescence signal closely followed the variation of indoor bioaerosol concentration in colony forming unit (CFU) and 1 RLU corresponded to 1.66 CFU m-3 of indoor bioaerosols. Our method can be used as a trigger in biological air contamination alarm systems. PMID- 27692375 TI - Development and validation of an at-line fast and non-destructive Raman spectroscopic method for the quantification of multiple components in liquid detergent compositions. AB - Implementation of process analytical technology (PAT) tools in the manufacturing process of liquid detergent compositions should allow fast and non-destructive evaluation of the product quality. The aim of this study was to develop and validate a rapid method for quantifying the chemical compounds of five washing liquid precursors. Raman spectroscopy was applied in combination with a two-step multivariate modeling procedure. In first instance, a SIMCA (Soft Independent Modeling of Class Analogy) model was developed and validated, allowing the distinction between the different laundry detergents. Once the product was correctly identified, it was aimed at predicting the concentration of its individual components using partial least squares (PLS) models. Raman spectra were collected at-line with a total acquisition time of 20 s, using a non-contact fiber-optic probe. The SIMCA model was perfectly capable of differentiating between the classes of the laundry liquid precursors. Per detergent, the concentration of at least three main ingredients could be predicted with a recovery between 98% and 102% and a standard deviation below 2.5%. Accuracy profiles based on the analysis results of validation samples were then calculated to prove the reliability of the developed regression models. beta-expectation tolerance intervals were calculated for each model and for each validated concentration level. The acceptance limits were set at 5% relative bias, indicating that at least 95% of future measurements should not deviate more than 5% from the true value. Furthermore, based on the data of the accuracy profiles, the measurement uncertainty was determined. The developed Raman spectroscopic method demonstrated to be able to rapidly and adequately determine the concentration of the components of interest in the liquid detergent compositions at-line. PMID- 27692376 TI - Nickel electrodes as a cheap and versatile platform for studying structure and function of immobilized redox proteins. AB - Practical use of many bioelectronic and bioanalytical devices is limited by the need of expensive materials and time consuming fabrication. Here we demonstrate the use of nickel electrodes as a simple and cheap solid support material for bioelectronic applications. The naturally nanostructured electrodes showed a surprisingly high electromagnetic surface enhancement upon light illumination such that immobilization and electron transfer reactions of the model redox proteins cytochrome b5 (Cyt b5) and cytochrome c (Cyt c) could be followed via surface enhanced resonance Raman spectroscopy. It could be shown that the nickel surface, when used as received, promotes a very efficient binding of the proteins upon preservation of their native structure. The immobilized redox proteins could efficiently exchange electrons with the electrode and could even act as an electron relay between the electrode and solubilized myoglobin. Our results open up new possibility for nickel electrodes as an exceptional good support for bioelectronic devices and biosensors on the one hand and for surface enhanced spectroscopic investigations on the other hand. PMID- 27692377 TI - ICE Concentration Linked with Extractive Stirrer (ICECLES). AB - Trace and ultra-trace analysis can be difficult to achieve, especially for polar, more volatile, and/or thermally unstable analytes. A novel technique, coined ICE Concentration Linked with Extractive Stirrer (ICECLES), may help address this problem. The implementation of ICECLES described here combines stir bar sorptive extraction (SBSE) with freeze concentration (FC), where an aqueous solution is frozen during SBSE in order to concentrate analytes into a polydimethylsiloxane (PDMS) coated stir bar. Five test probe molecules with a range of log Kows (2 butanol, benzyl alcohol, benzaldehyde, dimethyl trisulfide and bromobenzene) were prepared from aqueous solutions using ICECLES. Thermal desorption gas chromatography mass-spectrometry was then used to quantify these analytes. Parameters affecting the performance of ICECLES (e.g., freeze rate) were evaluated, with extraction at lower speeds resulting in higher extraction efficiencies, whereas the freeze rate and initial analyte concentration only had a minor effect. ICECLES produced much higher extraction efficiencies than SBSE alone, with signal enhancements of up to 474* SBSE. ICECLES also provided excellent reproducibility and lower LODs than SBSE for all compounds tested. ICECLES performed well when used to analyze multiple triazine pesticides and breakdown products in environmental surface waters. Overall, the ICECLES technique was excellent at preparing aqueous samples for trace analysis and shows promise as a novel analytical sample preparation technology. PMID- 27692378 TI - Automated peak width measurements for targeted analysis of ion mobility unresolved species. AB - Peak broadening in ion mobility (IM) is a relatively predictable process and abnormally broad peaks can be indicative of the presence of unresolved species. Here, we introduce a new ion mobility peak fitting (IM_FIT) software package for automated and systematic determination of traveling wave ion mobility (TWIM) unresolved species. To identify IM unresolved species, the IM_FIT software generates a trend line by plotting ions' mobility peak widths as a function of their arrival times. Utilizing user-defined thresholds, IM_FIT allows for automated and rapid detection of ions that deviate from the peak width trend line. To demonstrate the advantages of IM_FIT for automated detection of IM unresolved species, IM-mass spectrometry (IM-MS) data from a sample mixture containing polypropylene glycol and multiple peptides were analyzed. A total of 14 out of the 34 observed singly-charged IM peaks above 5% relative abundance (i.e., signal-to-noise ratios above ~200) were tagged as potentially co-eluting ions by IM_FIT. Subsequently, the 14 IM peaks tagged as potentially unresolved (presumably, peaks corresponding to co-eluting compounds), were further analyzed by automated IM deconvolution (AIMD), liquid chromatography-IM-MS (LC-IM-MS), and/or ultra-high resolution mass spectrometry. Using the aforementioned techniques, more than 85% of the tagged IM peaks (12 out of 14) were confirmed to contain co-eluting ions. As an additional new finding, IM_FIT facilitated the discovery of an unexpected sequence-scrambled y-type fragment ion. PMID- 27692379 TI - Measuring urinary N-acetyl-S-(4-hydroxy-2-methyl-2-buten-1-yl)-L-cysteine (IPMA3) as a potential biomarker of isoprene exposure. AB - Isoprene, the 2-methyl analog of 1,3-butadiene, is identified as a possible human carcinogen by the International Agency for Research on Cancer (IARC). Isoprene is ubiquitous in the environment with numerous natural and anthropogenic sources. Tobacco smoke is the main exogenous source of isoprene exposure in indoor environments. Among smoke constituents, isoprene is thought to contribute significantly to cancer risk; however, no selective urinary biomarkers of isoprene exposure have been identified for humans. In this manuscript, we measured the minor isoprene metabolite IPMA1 (mixture of N-acetyl-S-(1 [hydroxymethyl]-2-methyl-2-propen-1-yl)-L-cysteine and N-acetyl-S-(2-hydroxy-3 methyl-3-buten-1-yl)-L-cysteine), and we identified IPMA3 (N-acetyl-S-(4-hydroxy 2-methyl-2-buten-1-yl)-L-cysteine) as a major isoprene metabolite and novel isoprene exposure biomarker for humans. Urinary isoprene metabolites were measured using ultra high performance liquid chromatography coupled with electrospray ionization triple quad tandem mass spectrometry (UPLC/ESI-MSMS). The detection rates of IPMA1 and IPMA3 are <20% and 82%, respectively. The selectivity and abundance of IPMA3 make it a useful urinary biomarker of isoprene exposure. The limit of detection of IPMA3 in urine was 0.5 ng mL-1. IPMA3 was stable under different storage temperatures and following ten freeze-thaw cycles. The average recovery of urine spiked with IPMA3 at three different levels was 99%. IPMA3 was measured in urine samples received from 75 anonymous subjects; the median (25th percentile, 75th percentile) IPMA3 level in smokers was 36.2 (18.2, 56.8) ng mL-1 and non-smokers 2.31 (2.31, 4.38) ng mL-1. Application of this method to large population studies will help to characterize isoprene exposure and assess potential health impact. PMID- 27692380 TI - Analyses of trace amounts of dyes with a new enhanced sensitivity FTIR spectroscopic technique: MU-ATR (metal underlayer ATR spectroscopy). AB - The identification of organic dyes is a challenging task in all the fields such as the forensic and conservation sciences, especially in cases where the amount of sample is extremely small. In this paper we propose a new enhanced FTIR method (MU-ATR metal underlayer ATR spectroscopy), which we believe is the first of its kind, for the analysis of a few ng of dyes. With this method, dyed fiber micro extracts can be analyzed using a commercial FTIR microscope with a fixed incident angle, obtaining the same separation between the different classes of dyes investigated as we obtained analyzing pure dyes in transmission mode. Moreover, the new enhancement method has been validated on a real sample dated back to the 1893, showing how it can be promising for the analysis of trace amounts of organic substances in artistic samples such as dyes in paintings or textiles, varnishes and organic residues on archaeological objects. PMID- 27692381 TI - Protein determination using graphene oxide-aptamer modified gold nanoparticles in combination with Tween 80. AB - Recently, graphene oxide (GO) has shown superiority for disease detection arising from its unique physical and chemical properties. However, proteins adsorbed on the surface of GO prevent sensitivity improvement in fluorescence-based detection methods. In this paper, a label-free method based on aptamer modified gold nanoparticles (GNPs) combined with Tween 80 was shown to solve this problem using the detection of thrombin as an example. An aptamer was designed and bound to thrombin by changing its conformation. Tween 80 was used for rapid and reproducible synthesis of stable DNA-functionalized GNPs and prevented the thrombin from nonspecific binding to GO. Thrombin was detected with a limit of 0.68 pM by taking advantage of the efficient cross-linking effect of aptamer-GNPs to GO. The sensor was validated by determining thrombin concentration in human blood serum samples. The results indicate that this method has promising analytical application in medical diagnostic. PMID- 27692382 TI - Peroxidase-like catalytic activity of copper ions and its application for highly sensitive detection of glypican-3. AB - Glypican-3 (GPC3) might be used as new biomarker of liver cancer for the development of new diagnostic methods. The most commonly used methods for protein detection are based on natural enzymes, which are easily affected by environmental conditions and suffer from the rigorous preparation conditions. Thus, the development of new enzyme mimetics with high and stable catalytic activity is of great significance in diagnostic applications. In this paper, copper ions (Cu2+) was found to possess the peroxidase-like catalytic activity, which can catalyze H2O2-mediated oxidation of peroxidase substrate and obtain the oxidation product with color change. This catalytic activity is much more stable than other nanomaterials based peroxidase mimetics, and can significantly increase by increasing the concentration of H2O2. It is worth mentioning that the absorbance signal induced by 5 nM Cu2+ can be easily detected. This Cu2+ catalyzed reaction can be also applied in the detection of GPC3 by using the anti GPC3 antibody functionalized CuO NPs, which can release the Cu2+ by dissolved in HCl solution. This method permits detection of as low as 0.26 pg mL-1 GPC3. This sensitivity is about one or several magnitudes higher than that of ELISA or other peroxidase mimetics based methods. The high catalytic activity of Cu2+ and the signal amplification process of CuO NPs into high amount of Cu2+ also make this method more simple and effective. PMID- 27692383 TI - Application of DNA aptamers as sensing layers for detection of carbofuran by electrogenerated chemiluminescence energy transfer. AB - In this study, an electrogenerated chemiluminescence (ECL) sensing platform for carbofuran detection was constructed based on ECL energy transfer (ECRET) and carbon dot (C-dot)-tagged aptamers as the recognition element. Fullerene (C60) loaded gold nanoparticles (C60-Au) were used as the energy donor, modified on a glassy carbon electrode. C-dot-tagged DNA aptamers were used as the receptor, and ECRET then occurred between C60-Au and C-dots. After accepting the energy, the C dots acted as a signal indicator and showed decreased signal intensity in the presence of targets, which competitively bound to DNA aptamers and blocked energy transfer. Using this robust, straight-forward strategy, the sensor showed a linear ECL response to carbofuran at concentrations from 2.0 * 10-11 mol L-1 to 8.0 * 10-9 mol L-1. The detection limit of this assay was shown to be 8.8 * 10-13 mol L-1. Thus, the sensing approach described in this study could be adapted for use in the detection of various pesticide residue targets.

Results from a French population with chronic kidney disease]. AB - Leaflets inside drug boxes are complex and often poorly understood. Patients consulting in nephrology are mostly old and often suffer from multiple comorbidities. As so, they are often subject to various contra-indications and drug interactions. This paper aims to evaluate if patients actually read leaflets or other medical information on others medias such as Internet and whether this could, potentially, interfere with their observance. Results showed that leaflets were read by 65.1% of patients, leading to 12% of withdrawal or not taking drugs. Furthermore, compliance to medical guidance was deemed e-read by 65.1% of patients, leading to 12% of withdrawal or not taken drugs. Furthermore, this study showed no clear profile for non-compliant patients. Even the youngest patients (under 50 years old) have had a good compliance, with not more withdrawal or not taking pills. Nonetheless, youngest patients used more often to consult alternative medias and did not read much of the leaflets' information. Patients who were reading leaflets however, tended to search further information on other medias. This situation would create new challenges in health care, as it seems that data available on new medias are not systematically validated or adapted to the needs of the patients. PMID- 27692386 TI - The European Portuguese adaptation of the Fear of Pain Questionnaire. AB - In Portugal, it is estimated that chronic pain affects 36.7% of the population, constituting a multifactorial phenomenon with great impact at individual, family, community, and social levels. In the fear-avoidance model of pain, one of the most consistent consensual in the literature, the fear arises as one of the variables that can contribute to the development and maintenance of this condition. Thus, instruments for evaluating the fear of pain, as Fear of Pain Questionnaire (FPQ-III), may be useful in the conceptualization of the subjective experience of pain. Accordingly, this paper aims to describe the adaptation of FPQ-III for the European Portuguese. A total of 1094 participants (795 women; mean age=25.16, SD=7.72) completed the web based questionnaire. The results pointed to a different factor solution found in the first study of the original scale (five factors: minor pain, severe pain, medical pain, injection pain, and afflicted pain), good internal consistency (.75-.85) and good correlations (between .30 and .59) between subscales and (between .68 and .85) for the total score and subscales. Given the need to meet the various dimensions of subjective experience of pain, the Fear of Pain Questionnaire is assumed as a useful tool, in combination with other, may contribute to the evaluation and intervention procedures progressively more comprehensive and adjusted to the challenges raised with the issue of chronic pain. PMID- 27692387 TI - A prospective study predicting the outcome of chronic low back pain and physical therapy: the role of fear-avoidance beliefs and extraspinal pain. AB - OBJECTIVE: To identify the prognostic factors for conventional physical therapy in patients with chronic low back pain (CLBP). METHODS: Prospective observational study. PARTICIPANTS: One hundred thirteen patients with CLBP selected at the Spinal Disease Outpatient Clinic. MAIN OUTCOME MEASURES: Pain intensity was scored using the Numeric Rating Scale (NRS), and function was measured using the Roland-Morris Disability Questionnaire (RMDQ). RESULTS: The Fear-Avoidance Beliefs Questionnaire work subscale results (FABQ-work; odds ratio [OR]=0.27, 95% confidence interval [CI] 0.13-0.56, p<0.001) and extraspinal pain (OR=0.35, 95% CI 0.17-0.74, p=0.006) were independently associated with a decreased response to conventional physical therapy for CLBP. CONCLUSION: We identified high FABQ-work and extraspinal pain scores as key determinants of a worse response to physical therapy among CLBP patients, supporting the need for a special rehabilitation program for this subgroup. PMID- 27692388 TI - High frequency of asymptomatic hyperparathyroidism in patients with fibromyalgia: random association or misdiagnosis? AB - : Fibromyalgia (FM) and hyperparathyroidism may present similar symptoms (musculoskeletal pain, cognitive disorders, insomnia, depression and anxiety), causing diagnostic confusion. OBJECTIVES: To determine the frequency of asymptomatic hyperparathyroidism in a sample of patients with FM and to evaluate the association of laboratory abnormalities to clinical symptoms. METHODS: Cross sectional study with 100 women with FM and 57 healthy women (comparison group). Parathyroid hormone (PTH), calcium and albumin levels were accessed, as well as symptoms in the FM group. RESULTS: In FM group, mean serum calcium (9.6+/ 0.98mg/dL) and PTH (57.06+/-68.98pg/mL) values were considered normal, although PTH levels had been significantly higher than in the comparison group (37.12+/ 19.02pg/mL; p=0.001). Hypercalcemic hyperparathyroidism was diagnosed in 6% of patients with FM, and 17% of these women exhibited only high levels of PTH, featuring a normocalcemic hyperparathyroidism, with higher frequencies than those expected for their age. There was no significant association between hyperparathyroidism and FM symptoms, except for epigastric pain, which was more frequent in the group of patients concomitantly with both diseases (p=0.012). CONCLUSIONS: A high frequency of hyperparathyroidism was noted in women with FM versus the general population. Normocalcemic hyperparathyroidism was also more frequent in patients with FM. Longitudinal studies with greater number of patients are needed to assess whether this is an association by chance only, if the increased serum levels of PTH are part of FM pathophysiology, or even if these would not be cases of FM, but of hyperparathyroidism. PMID- 27692389 TI - The representation of getting ill in adolescents with systemic lupus erythematosus. AB - INTRODUCTION: This study, developed in a federal hospital in the city of Rio de Janeiro, has aimed to analyze the social representation of chronic disease and its treatment, in the perspective of adolescents and their caregivers. METHODS: The sample consisted of 31 adolescents (11-21 years) with systemic lupus erythematosus and 19 caregivers (32-66 years), followed in the pediatrics and in the internal medicine outpatient clinics for a period of six months. Data was collected from the free association of words test, using chronic disease and treatment of chronic disease impulses, and later submitted to the Multiple Correspondence Analysis using the R software. RESULTS: The group of adolescents associated the impulse chronic disease with the words medication, bad, illness, difficulty, no cure, faith and joy; and in the group of caregivers, to care, treatment, no cure and the word 'no'. The impulse treatment of chronic disease was associated, in the group of adolescents, with the words patience, improvement, help, affection, care and bad; and in the group of caregivers, to caring, hope, schedule, knowledge, obedience, medication, professional and improvement. Caregivers also associated impulses and words according to age: chronic disease was associated with the word care (over 61 years), pain and impotence (42-61 years), treatment (22-41 years); and treatment of chronic disease, with the words strength (over 61 years), professional, knowledge and improvement (42-61 years), affection and schedule (22-41 years). CONCLUSIONS: Considering as subjective and dynamic the experience of getting ill, knowing the representations can contribute to the orientation of conduct and type of psychotherapeutic intervention needed. PMID- 27692390 TI - Sensitivity and specificity of assessment instruments of quality of life in rheumatoid arthritis. AB - OBJECTIVE: To check sensitivity and specificity of assessment instruments of QoL in patients with rheumatoid arthritis (RA). METHODOLOGY: Accuracy study in a sample consisting of patients with confirmed diagnosis of RA. QoL questionnaires QV SF-36 (Gold Standard), HAQ and NHP were applied. The Pearson correlation coefficient, ROC curve, AUC and Youden Index (J) were used to analyze the data. RESULTS: This study enrolled 97 individuals with RA. The functional capacity estimated by SF-36 was correlated with the total score of HAQ (r=-0.666; p<0.001; J=0.579), while the emotional aspects of SF-36 were correlated with the emotional reactions domain of NHP (r=-0.316; p=0.005; J=0.341). The vitality domain of SF 36 was correlated with the level of energy of NHP (r=-0.362; p=0.001; J=0.302). For the evaluation of functional capacity (AUC=0.839; p<0.001) and physical aspect (AUC=0.755; p<0.001) the most accurate instrument was the HAQ. For evaluation of the impact of vitality, sleep (AUC=0.679; p=0.007), emotional reactions (AUC=0.674; p=0.009) and level of energy in QoL, the NHP (AUC=0.633; p=0.045) was the most specific and sensitive. In the evaluation of the emotional aspect domain, the most accurate instrument was the NHP in the "emotional reaction" score (AUC=0.699; p=0.003). The evaluation of pain was limited in the three instruments and SF-36 was the only one in assess of the domains of social aspects and general health status. CONCLUSION: For evaluation of the physical aspects in patients with RA, the HAQ is the most accurate. For evaluation of emotional aspects the NHP is the most indicated, although the SF-36 was the only one in the evaluation of general domains. PMID- 27692391 TI - Methylene tetrahydrofolate reductase, transforming growth factor-beta1 and lymphotoxin-alpha genes polymorphisms and susceptibility to rheumatoid arthritis. AB - BACKGROUND: Rheumatoid arthritis is a widely prevalent autoimmune disorder with suggested genetic predisposition. OBJECTIVES: The aim of this study is to detect the pattern of genetic polymorphism of methylene tetrahydrofolate reductase (MTHFR C677 T and A1298 C), transforming growth factor-beta1 (TGF-beta1 T869 C) and lymphotoxin-alpha (LT-alpha A252G) in patients having rheumatoid arthritis and correlate these patterns to disease activity and serum levels of tumor necrosis factor-alpha (TNF-alpha), B-Cell Activating Factor (BAFF), and osteopontin. METHODS: A total of 194 subjects, 90 controls and 104 patients with rheumatoid arthritis were genotyped for MTHFR C677 T and A1298 C, TGF-beta1 T869 C and LT-alpha A252G polymorphisms using a methodology based on PCR-RFLP. Also serum levels of TNF-alpha, osteopontin and BAFF were measured by ELISA kits. RESULTS: The CT genotype and T allele of MTHFR C677 T and GG genotype and G allele of LT-alpha A252G are associated with the risk of RA and with higher levels of the pro-inflammatory cytokine, TNF-alpha in patients with rheumatoid arthritis. CONCLUSION: Our findings suggest that there is association between MTHFR C677 T and LT-alpha A252G genes polymorphisms and increased risk of RA in this sample of Egyptian population. PMID- 27692392 TI - A new musculoskeletal ultrasound scoring system (US10) of the hands and wrist joints for evaluation of early rheumatoid arthritis patients. AB - OBJECTIVE: To propose a novel ultrasound scoring system for hand and wrist joints (US10) for evaluation of patients with early rheumatoid arthritis (RA) and to correlate the US10 with clinical, laboratory and functional variables. METHODS: Forty-eight early RA patients underwent clinical and laboratory evaluations as well as blinded ultrasound (US) examinations at baseline, three, six and 12 months. The proposed US10 system involved the assessment of the wrist, second and third metacarpophalangeal and proximal interphalangeal joints. The score consisted of inflammation parameters (synovial proliferation [SP], power Doppler [PD] and tenosynovitis [TN]) and joint damage parameters (bone erosion [BE] and cartilage damage [CD]). SP, PD, BE and CD were scored qualitatively (0-1) and semi-quantitatively (grades 0-3). Tenosynovitis was scored as presence/absence. The evaluation also involved the 28-Joint Disease Activity Score (DAS28), Health Assessment Questionnaire (HAQ) and C-reactive protein level (CRP). RESULTS: Mean duration of symptoms was 7.58+/-3.59 months. Significant correlations (p<0.05) were found between inflammation parameters and CRP at baseline and between the changes in these variables throughout the study. Significant correlations (p<0.05) were found between DAS28 score and both PD and TN at baseline and between the changes in DAS28 score and both SP and TN throughout the follow up. Moreover, significant correlations were found between the changes in inflammation parameter scores and HAQ score throughout the follow up. CONCLUSION: The proposed US10 scoring system proved to be a useful tool for monitoring inflammation and joint damage in early RA patients, demonstrating significant correlations with longitudinal changes in disease activity and functional status. PMID- 27692393 TI - Clinical characteristics and frequency of TLR4 polymorphisms in Brazilian patients with ankylosing spondylitis. AB - OBJECTIVES: Innate immunity is involved in the physiopathology of ankylosing spondylitis (AS), with the participation of Gram-negative bacteria, modulation of human leukocyte antigen (HLA) B27 and the involvement of pattern recognition receptors, such as Toll-like receptors (TLRs). The aim of this study was to investigate the clinical characteristics and frequency of TLR4 polymorphisms (Asp299Gly and Thr 399Ile) in a cohort of Brazilian patients with AS. METHODS: A cross-sectional study was carried out involving 200 patients with a diagnosis of AS and a healthy control group of 200 individuals. Disease activity, severity and functional capacity were measured. The study of TLR4 polymorphisms was performed using the restriction fragment length polymorphism method. HLA-B27 was analyzed by conventional polymerase chain reaction. The IBM SPSS Statistics 20 program was used for the statistical analysis, with p-values less than 0.05 considered significant. RESULTS: Mean age and disease duration were 43.1+/-12.7 and 16.6+/ 9.2 years, respectively. The sample was predominantly male (71%) and non Caucasian (52%). A total of 66% of the group of patients were positive for HLA B27. The sample of patients was characterized by moderate functional impairment and a high degree of disease activity. No significant association was found between the two TLR4 polymorphisms and susceptibility to AS. CONCLUSIONS: TLR4 polymorphisms 399 and 299 were not more frequent in patients with AS in comparison to the health controls and none of the clinical variables were associated with these polymorphisms. PMID- 27692394 TI - What rheumatologists should know about orofacial manifestations of autoimmune rheumatic diseases. AB - Orofacial manifestations occur frequently in rheumatic diseases and usually represent early signs of disease or of its activity that are still neglected in clinical practice. Among the autoimmune rheumatic diseases with potential for oral manifestations, rheumatoid arthritis (RA), inflammatory myopathies (IM), systemic sclerosis (SSc), systemic lupus erythematosus (SLE), relapsing polychondritis (RP) and Sjogren's syndrome (SS) can be cited. Signs and symptoms such as oral hyposalivation, xerostomia, temporomandibular joint disorders, lesions of the oral mucosa, periodontal disease, dysphagia, and dysphonia may be the first expression of these rheumatic diseases. This article reviews the main orofacial manifestations of rheumatic diseases that may be of interest to the rheumatologist for diagnosis and monitoring of autoimmune rheumatic diseases. PMID- 27692395 TI - IL33 in rheumatoid arthritis: potential contribution to pathogenesis. AB - A better understanding of the inflammatory mechanisms of rheumatoid arthritis and the development of biological therapy revolutionized its treatment, enabling an interference in the synovitis - structural damage - functional disability cycle. Interleukin 33 was recently described as a new member of the interleukin-1 family, whose common feature is its pro-inflammatory activity. Its involvement in the pathogenesis of a variety of diseases, including autoimmune diseases, raises the interest in the possible relationship with rheumatoid arthritis. Its action has been evaluated in experimental models of arthritis as well as in serum, synovial fluid and membrane of patients with rheumatoid arthritis. It has been shown that the administration of interleukin-33 exacerbates collagen-induced arthritis in experimental models, and a positive correlation between cytokine concentrations in serum and synovial fluid of patients with rheumatoid arthritis and disease activity was found. This review discusses evidence for the role of interleukin-33 with a focus on rheumatoid arthritis. PMID- 27692396 TI - Rituximab for the therapy of systemic sclerosis: a series of 10 cases in a single center. AB - : Systemic sclerosis (SSc) is a chronic autoimmune disease with a high morbidity and mortality. Although cyclophosphamide is effective for severe and refractory cases, there is demand for new treatments. The biological treatment with B-cell depletion with rituximab (RTX) has demonstrated efficacy for this demand in open label studies. OBJECTIVE: This study was conducted with the aim to retrospectively evaluate all patients who used RTX for the treatment of SSc in our center. PATIENTS AND METHODS: We retrospectively evaluated medical records of all patients with SSc who used RTX to treat this disease from January 2009 to January 2015. Systemic, cutaneous, and pulmonary involvement data and laboratory results before and six months after the first infusion of RTX were collected. RESULTS: Ten patients received treatment during the study period and were included in this series. All patients had a diffuse form of the disease. Five patients suffered from an early (duration of disease shorter or equal to four years), rapidly progressive disease, and another five received RTX at late stages of the disease. In both groups of patients, stabilization of the pulmonary picture was observed, with a fall in the skin score in those patients with early forms of the disease. DISCUSSION: Similar to findings in previous studies, RTX was effective in treating early and rapidly progressive forms of SSc. We also found that patients with long-term illness may benefit from the treatment. PMID- 27692397 TI - Did Father Cicero suffer from rheumatism? AB - Father Cicero Romao Batista is probably the most famous Ceara character of all time. An important protagonist of the Cariri region, situated in the south of Ceara State, in the late nineteenth century and the first third of the twentieth century, Father Cicero had great political and religious activity, as well as other less well-known achievements, for instance, his ecological teachings that led him to be awarded the title of "Patron of Forests", besides an enormous effort and personal sacrifice for the improvement of the conditions of human life. Inspired by reading his biography, we find that the "Padim Cico" could have inflammatory spondyloarthropathy. In this article, we present the plausibility of this diagnostic hypothesis, seeking to emphasize that an attentive ear and clinical observation, albeit indirectly and without the privilege of a personal contact with the patient, are unparalleled tools for bringing forth a diagnosis. PMID- 27692399 TI - Acetylcholine-induced ex vivo ATP release from the human nasal mucosa. AB - OBJECTIVE: The present study aimed at investigating ATP release in response to acetylcholine (Ach) and pharmacologically elucidating the intracellular signal transduction pathway of this reaction in an ex vivo experiment. METHODS: The inferior turbinate mucosa was collected from 21 patients with chronic hypertrophic rhinitis who underwent endoscopic turbinectomy. The mucosa was shaped into a filmy round piece, and incubated with chemical(s) in Hank's balanced salt solution for 10min. After incubation, the ATP concentration was measured by a luciferin-luciferase assay. RESULTS: The baseline release of ATP without stimulus was 57.2+/-10.3fM. The ATP release was significantly increased by stimulation with 100MUM Ach. The Ach-induced ATP release was completely inhibited by removing extracellular Ca2+. Significant inhibition of the Ach induced ATP release was also observed by the addition of 1MUM atropine, 40MUM 2 APB, 10MUM CBX, and 100MUM PPADS, whereas 30nM bafilomycin A1 did not affect the ATP release. CONCLUSION: These results indicate that the Ach-induced ATP release from the human nasal mucosa is dependent on the pannexin-1 channel and purinergic P2X7 receptor, suggesting that these two molecules constitute a local autocrine/paracrine signaling system in the human nasal epithelium. PMID- 27692398 TI - New approach in lung cancer radiotherapy offers better normal tissue sparing. AB - PURPOSE: Medical images are more than pictures. They contain additional quantitative information which can be interrogated, quantified, and utilized. Besides anatomical information computed tomography (CT) imaging data provide electron density information. Radiotherapy use of this density information is limited to its application only in dose calculations. The direct product of dose, density, and volume forms a quantity called integral dose. The integral dose delivered to a volume of interest is the total energy deposited in that volume. Here it is hypothesized that minimization of the integral dose is advantageous in radiotherapy planning. The purpose of this work is to study the incorporation of quantitative imaging information in radiotherapy inverse optimization through total energy minimization (Energy hereafter). DESIGN: Twenty lung patient plans were studied. For each patient density was quantified on voxel-by-voxel basis through image gray value-to-density conversion curves. Energy-based objective function was used for inverse radiotherapy plan optimization. The obtained plans were evaluated in the light of current standard of care, based on dose-volume (DVH) optimization approach. RESULTS: The statistical significance analyses of the results indicated that the doses to normal tissue were between 14% and 45% lower, when Energy-based optimization was used instead of DVH-based optimization. CONCLUSION: Incorporation of quantitative imaging information, through CT derived density, in the optimization cost function allows reduction of dose to normal tissue for NSCLC cases. Energy-based radiotherapy plans result in lower normal tissue dose and potentially lower complication rates compared to standard of care. PMID- 27692400 TI - The role of nasal fractional exhaled nitric oxide as an objective parameter independent of nasal airflow resistance in the diagnosis of allergic rhinitis. AB - OBJECTIVE: Patients with allergic rhinitis (AR) show augmented activity of nitric oxide (NO) metabolism, similar to those in bronchial asthma (BA). We hypothesized that measurements of nasal fractional exhaled NO (FeNO) could be used as an objective marker to detect the presence of AR. Our objective was to clarify the influence of nasal airflow resistance (NAR) on nasal FeNO levels through an exhalation maneuver in symptomatic AR patients. We also examined the diagnostic test validity of the mean nasal FeNO level for disease discrimination by means of a receiver operating characteristic (ROC) curve analysis. METHODS: Fifty-nine untreated perennial AR patients without BA and 60 healthy controls were enrolled in this retrospective cross-sectional study. The subjective symptoms were recorded and the disease severity was classified according to the Japanese guideline for AR. The oral and nasal FeNO measurements were carried out using a handheld electrochemical analyzer according to the ATS/ERS guidelines. NAR was measured using a rhinomanometer by the anterior method. RESULTS: The patients in the moderate-to-most severe AR group showed significantly higher levels of oral FeNO compared to the controls. The AR patients in both the mild (n=25) and the moderate-to-most severe (n=34) groups showed significantly higher levels of nasal FeNO compared to the controls (44.1ppb, 54.5ppb, and 26.5ppb, respectively). There was no significant difference in total NAR between the AR patients and the controls. The results of our comparison of nasal FeNO and NAR values of the ipsilateral nasal cavity for each individual indicated no significant correlation between the two-paired parameters. The optimal cut-off point of the mean nasal FeNO level was calculated as 38.5ppb (with 71% sensitivity and 86% specificity) to discriminate the presence of AR. CONCLUSION: Nasal FeNO measurements can be an objective parameter for the diagnosis and classification of perennial AR in Japanese individuals. Nasal FeNO and NAR appear to be two independent measures that can be used to objectively evaluate nasal functions.

AB - INTRODUCTION: Our objective was to analyze the surface and bulk properties alterations of clinically aged composites used for fixed retention. METHODS: Twenty-six lingual retainers bonded for different time periods (2.2-17.4 years) were retrieved from postorthodontic patients. Fifteen lingual retainers had been cemented by a chemically cured adhesive (Maximum Cure, Reliance Orthodontic Products, Itasca, Ill), and 11 were treated with a photo-cured adhesive (Flow Tain, Reliance Orthodontic Products). The first group was in service for 2.8 to 17.4 years and the second for 2.2 to 5.4 years. Five specimens from each material were prepared and used as the control (or reference) group. The debonded surfaces from enamel were studied by attenuated total reflectance Fourier transform infrared spectroscopy (n = 3 per material per group), low-vacuum scanning electron microscopy, and energy dispersive x-ray microanalysis (n = 3 per material per group). All specimens were used for the assessment of Vickers hardness, indentation modulus, and elastic index with the instrumented indentation testing method. The values of Vickers hardness, indentation modulus, and elastic index were compared between the retrieved and the reference groups with 1-way analysis of variance and the Student-Newman-Keuls multiple comparison test (alpha = 0.05). RESULTS: The attenuated total reflectance Fourier transform infrared spectroscopy analysis showed that both retrieved composites demonstrated reduced unsaturation in comparison with the corresponding reference specimens. Some bonded surfaces showed development of organic integuments. All retrieved specimens showed reduced silicon content. Barium was identified only in the photo cured group. No significant differences were found between the reference and retrieved groups in Vickers hardness, indentation modulus, and elastic index. CONCLUSIONS: Despite the changes in composition, the mechanical properties of the materials tested remained unaffected by intraoral aging. PMID- 27692413 TI - Dentoskeletal outcomes of a rapid maxillary expander with differential opening in patients with bilateral cleft lip and palate: A prospective clinical trial. AB - INTRODUCTION: The purpose of this 2-arm parallel study was to evaluate the dentoskeletal effects of rapid maxillary expansion with differential opening (EDO) compared with the hyrax expander in patients with complete bilateral cleft lip and palate. METHODS: A sample of patients with complete bilateral cleft lip and palate was prospectively and consecutively recruited. Eligibility criteria included participants in the mixed dentition with lip and palate repair performed during early childhood and maxillary arch constriction with a need for maxillary expansion before the alveolar bone graft procedure. The participants were consecutively divided into 2 study groups. The experimental and control groups comprised patients treated with rapid maxillary expansion using EDO and the hyrax expander, respectively. Cone-beam computed tomography examinations and digital dental models of the maxillary dental arches were obtained before expansion and 6 months postexpansion. Standardized cone-beam computed tomography coronal sections were used for measuring maxillary transverse dimensions and posterior tooth inclinations. Digital dental models were used for assessing maxillary dental arch widths, arch perimeters, arch lengths, palatal depths, and posterior tooth inclinations. Blinding was used only during outcome assessment. The chi-square test was used to compare the sex ratios between groups (P <0.05). Intergroup comparisons were performed using independent t tests with the Bonferroni correction for multiple tests. RESULTS: Fifty patients were recruited and analyzed in their respective groups. The experimental group comprised 25 patients (mean age, 8.8 years), and the control group comprised 25 patients (mean age, 8.6 years). No intergroup significant differences were found for age, sex ratio, and dentoskeletal variables before expansion. No significant differences were found between the EDO and the hyrax expander groups regarding skeletal changes. The EDO promoted significantly greater increases of intercanine width (difference, 3.63 mm) and smaller increases in canine buccal tipping than the conventional hyrax expander. No serious harm was observed other than transitory variable pressure sensations on the maxillary alveolar process in both groups. CONCLUSIONS: The EDO produced skeletal changes similar to the conventional hyrax expander. The differential expander is an adequate alternative to conventional rapid maxillary expanders when there is need for greater expansion in the maxillary dental arch anterior region. REGISTRATION: This trial was not registered. PROTOCOL: The protocol was not published before trial commencement. FUNDING: This study received financial support from FAPESP (process number 2009/17622-9). As a possible conflict of interest, a patent with an EDO was submitted in March 2011 to the National Institute of Industry Property and is still in process. However, we believe that this is a natural step of translational research (bench-to bedside), and we guarantee that the scientific results are true. PMID- 27692415 TI - Root resorption in Class II malocclusion treatment with Class II elastics. AB - INTRODUCTION: The objective of this investigation was to compare the amount of apical root resorption in nonextraction treatment of Class II malocclusions with and without Class II elastics. METHODS: A sample of 54 patients with Class II Division 1 malocclusion, retrospectively selected, was divided into 2 groups. The elastic group consisted of 27 patients who were exclusively treated with fixed appliances associated with elastics, and the headgear group consisted of 27 patients treated with fixed appliances and extraoral headgear. The groups were matched regarding initial age, treatment time, amount of overjet, initial malocclusion severity, final occlusal status, and severity of Class II molar relationship. Posttreatment periapical radiographs of the maxillary and mandibular central and lateral incisors were used to evaluate root resorption. The amounts of resorption in the groups were compared with Mann-Whitney U tests. RESULTS: There was no statistically significant difference in the amounts of root resorption between the elastic and the headgear groups. CONCLUSION: Nonextraction treatment of Class II malocclusions with Class II elastics associated with fixed appliances causes similar root resorption as treatment with extraoral headgear and fixed appliances. Apical root resorption was predominantly mild and similar in the 2 groups. PMID- 27692416 TI - Mixed-methods assessment of perceptions of mandibular anterior malalignment and need for orthodontic retreatment. AB - INTRODUCTION: Postorthodontic occlusal changes may stem from true relapse or may be a consequence of characteristic temporal changes. The aims of this research were to identify occlusal discrepancies related to the mandibular labial segment prompting a decision to undergo orthodontic retreatment. METHODS: A mixed-methods assessment was undertaken comprising a qualitative analysis involving focus groups exploring the relative importance of a range of occlusal features in the decision to undergo retreatment and investigating the motives for seeking retreatment. Quantitative assessment of these occlusal discrepancies was undertaken by 50 lay and 50 professional raters. RESULTS: Several themes were identified in the qualitative analysis, with dental esthetics a major motive in seeking retreatment; variations in both the perception of relapse and retainer wear were identified. Horizontal irregularities of the mandibular anterior teeth were consistently perceived as the most severe. The professionals had slightly higher odds for suggesting the need for retreatment than did the laypeople, although this did not have statistical significance (odds ratio, 1.23; 95% confidence interval, 0.52-2.19; P = 0.65). CONCLUSIONS: The perception of mandibular labial segment irregularity and its influence on the need for orthodontic retreatment are complex and multifaceted. Nevertheless, horizontal discrepancies of the mandibular incisors were regarded as the most significant by both lay and professional raters. PMID- 27692417 TI - Objective method for evaluating orthodontic treatment from the lay perspective: An eye-tracking study. AB - INTRODUCTION: Currently, few methods are available to measure orthodontic treatment need and treatment outcome from the lay perspective. The objective of this study was to explore the function of an eye-tracking method to evaluate orthodontic treatment need and treatment outcome from the lay perspective as a novel and objective way when compared with traditional assessments. METHODS: The scanpaths of 88 laypersons observing the repose and smiling photographs of normal subjects and pretreatment and posttreatment malocclusion patients were recorded by an eye-tracking device. The total fixation time and the first fixation time on the areas of interest (eyes, nose, and mouth) for each group of faces were compared and analyzed using mixed-effects linear regression and a support vector machine. The aesthetic component of the Index of Orthodontic Treatment Need was used to categorize treatment need and outcome levels to determine the accuracy of the support vector machine in identifying these variables. RESULTS: Significant deviations in the scanpaths of laypersons viewing pretreatment smiling faces were noted, with less fixation time (P <0.05) and later attention capture (P <0.05) on the eyes, and more fixation time (P <0.05) and earlier attention capture (P <0.05) on the mouth than for the scanpaths of laypersons viewing normal smiling subjects. The same results were obtained when comparing posttreatment smiling patients, with less fixation time (P <0.05) and later attention capture on the eyes (P <0.05), and more fixation time (P <0.05) and earlier attention capture on the mouth (P <0.05). The pretreatment repose faces exhibited an earlier attention capture on the mouth than did the normal subjects (P <0.05) and posttreatment patients (P <0.05). Linear support vector machine classification showed accuracies of 97.2% and 93.4% in distinguishing pretreatment patients from normal subjects (treatment need), and pretreatment patients from posttreatment patients (treatment outcome), respectively. CONCLUSIONS: The eye-tracking device was able to objectively quantify the effect of malocclusion on facial perception and the impact of orthodontic treatment on malocclusion from the lay perspective. The support vector machine for classification of selected features achieved high accuracy of judging treatment need and treatment outcome. This approach may represent a new method for objectively evaluating orthodontic treatment need and treatment outcome from the perspective of laypersons. PMID- 27692418 TI - Craniofacial characteristics of children with mild hypodontia. AB - INTRODUCTION: The aim of our study was to evaluate the craniofacial characteristics of children with mild hypodontia using conventional and principal component (PC) analysis. METHODS: We used radiographic images of 124 children (8 12 years old) with up to 4 missing teeth (55 boys, 69 girls) and of 676 reference children (365 boys, 311 girls) from the Rotterdam Generation R Study and the Nijmegen Growth Study in The Netherlands. Fifteen cephalometric measurements of children with hypodontia were compared with those of the reference children. Moreover, cephalometric parameters were combined into standardized PC scores using PC analysis, and the components were compared between the 2 groups. RESULTS: PC analysis showed common dental characteristics for all types of hypodontia: a significant increase of the interincisal angle, and decreases of the maxillary and mandibular incisor angles. Other findings were consistent when both methods were applied: (1) anterior hypodontia was significantly associated with the high-angle (hyperdivergent) craniofacial pattern, (2) the tendency toward a Class III malocclusion was identified in maxillary hypodontia, and (3) we observed a significant reduction of lower posterior facial height in children with posterior and mandibular hypodontia. CONCLUSIONS: Our findings suggest that children with mild hypodontia have distinctive skeletal and dental features. PMID- 27692419 TI - Tooth replacements in young adults with severe hypodontia: Orthodontic space closure, dental implants, and tooth-supported fixed dental prostheses. A follow up study. AB - INTRODUCTION: Children with severe hypodontia have a substantial impairment of their dental health starting early in life. The purpose of this study was to describe types and locations of substitutes for missing teeth in patients with severe hypodontia and to compare the crown and soft tissue morphologies of orthodontic space closure, dental implants, and tooth-supported fixed dental prostheses for replacing teeth in the anterior region. METHODS: Fifty patients missing 6 or more teeth and aged 18 years or older (mean age, 25.6 years) took part in a follow-up study. The patients were examined clinically with panoramic radiographs and clinical photographs. Crown and soft tissue variables (mucosal discoloration, crown morphology, color, and papilla index) were compared for orthodontic space closure, dental implant fixtures, and fixed dental prostheses. RESULTS: Dental implants, orthodontic space closure, and retaining deciduous teeth were the most commonly prescribed treatments. Persisting deciduous teeth showed a good survival rate at the follow-up examination. Mucosal discoloration was seen only for implant fixtures and was evident for almost all fixtures in the anterior mandible and two thirds of those in the anterior maxilla. The papilla index scored poorer for both implant fixtures and fixed dental prostheses compared with orthodontic space closure. CONCLUSIONS: Dental implants in the anterior region proved to be an inadequate treatment modality in patients with severe hypodontia because of pronounced mucosal discoloration. PMID- 27692420 TI - Dental esthetics and oral health-related quality of life in young adults. AB - INTRODUCTION: Dental esthetics affects how people are perceived by society and how they perceive themselves, and this may also affect their oral health-related quality of life (OHRQoL). The aim of this study was to compare the impacts of self-perceived and normatively assessed dental esthetics on the OHRQoL of a young adult population. METHODS: This was a cross-sectional descriptive study involving 375 undergraduate university students, aged 18 to 30 years old. Data collection was carried out through oral examinations and self-administered questionnaires. Dental esthetics of the students was assessed using the esthetic component of the Index of Orthodontic Treatment Need. Two OHRQoL instruments were used: the shortened version of the Oral Health Impact Profile and the Psychosocial Impact of Dental Aesthetics Questionnaire. RESULTS: Statistically significant relationships (P <0.05) were recorded between both self-perceived and normatively assessed dental esthetics of the students, respectively, and 3 of the 4 Psychosocial Impact of Dental Aesthetics Questionnaire subscales: dental self confidence (Kruskall-Wallis, P = 0.000; P = 0.000), psychological impact (P = 0.003, P = 0.047), and esthetic concern (P = 0.006, P = 0.003). The only exception was the social impact subscale, in which a significant relationship was recorded only with self-perceived dental esthetics (P = 0.040). For the shortened version of the Oral Health Impact Profile scale, marked differences were also observed between the impacts recorded for both self-assessments and normative assessments, respectively, particularly for the psychological disability domain (Fisher exact test, P = 0.021, P = 0.000; P = 0.064, P = 0.096). CONCLUSIONS: Differences exist between the impacts of self-perceived and normatively assessed dental esthetics on the OHRQoL of young adults, particularly in the psychosocial domains. These differences should be considered in orthodontic treatment planning for young adult populations. PMID- 27692421 TI - Association between frontal sinus morphology and cervical vertebral maturation for the assessment of skeletal maturity. AB - INTRODUCTION: Various methods have been proposed to evaluate a patient's developmental status. However, most of them lacked precision and failed to give a reliable estimate of skeletal maturity. The aims of this study were to evaluate the association between frontal sinus morphology and cervical vertebral maturation for the assessment of skeletal maturity and to determine its validity in assessing the different stages of the adolescent growth spurt. METHODS: A cross-sectional study was performed on the pretreatment lateral cephalograms of 252 subjects aged 8 to 21 years. The sample was divided into 6 groups based on the cervical vertebral maturation stages. The frontal sinus index was calculated by dividing the frontal sinus height and width, and the cervical stages were evaluated on the same radiograph. The Kruskal-Wallis test was applied to compare frontal sinus index values at different cervical stages, and the post hoc Dunnett T3 test was applied to compare frontal sinus index values between adjacent cervical stages for each sex. The Kendall tau-b values were computed to assess the correlation between the cervical stages and the sinus index. A P value of <=0.05 was considered statistically significant. RESULTS: The height and width of the frontal sinus were significantly larger in the male subjects than in the females. A significant association was found between the frontal sinus height and width and cervical stages (P <=0.001) in both sexes. However, the changes in the frontal sinus index across the different cervical stages were found to be significant (P <=0.001) in male subjects only. Similarly, a weak negative correlation was found between the sinus index and the cervical stages in male subjects (tau-b = -0.271; P <0.001), whereas no correlation was found in female subjects (tau-b = -0.006; P <0.928). However, the post hoc analysis showed that the values of the sinus index were comparable between any 2 adjacent cervical stages. CONCLUSIONS: The frontal sinus index cannot be used to identify the prepubertal, pubertal, and postpubertal stages of the adolescent growth spurt. Therefore, it cannot be used as a reliable maturity indicator. PMID- 27692422 TI - When static meets dynamic: Comparing cone-beam computed tomography and acoustic reflection for upper airway analysis. AB - INTRODUCTION: Upper airway measurement can be important for the diagnosis of breathing disorders. Acoustic reflection (AR) is an accepted tool for studying the airway. Our objective was to investigate the differences between cone-beam computed tomography (CBCT) and AR in calculating airway volumes and areas. METHODS: Subjects with prescribed CBCT images as part of their records were also asked to have AR performed. A total of 59 subjects (mean age, 15 +/- 3.8 years) had their upper airway (5 areas) measured from CBCT images, acoustic rhinometry, and acoustic pharyngometry. Volumes and minimal cross-sectional areas were extracted and compared with software. RESULTS: Intraclass correlation on 20 randomly selected subjects, remeasured 2 weeks apart, showed high reliability (r >0.77). Means of total nasal volume were significantly different between the 2 methods (P = 0.035), but anterior nasal volume and minimal cross-sectional area showed no differences (P = 0.532 and P = 0.066, respectively). Pharyngeal volume showed significant differences (P = 0.01) with high correlation (r = 0.755), whereas pharyngeal minimal cross-sectional area showed no differences (P = 0.109). The pharyngeal volume difference may not be considered clinically significant, since it is 758 mm3 for measurements showing means of 11,000 +/- 4000 mm3. CONCLUSIONS: CBCT is an accurate method for measuring anterior nasal volume, nasal minimal cross-sectional area, pharyngeal volume, and pharyngeal minimal cross-sectional area. PMID- 27692423 TI - Determination of soft tissue thickness at orthodontic miniscrew placement sites using ultrasonography for customizing screw selection. AB - INTRODUCTION: A wide variety of factors affect the success of orthodontic miniscrews in clinical situations, including thickness of the soft tissues. Our objectives were to assess area-related and sex-related differences in the soft tissue thicknesses of the buccal attached gingiva of the maxilla and the mandible, and the palatal masticatory mucosa at common orthodontic miniscrew placement sites, and to prescribe a guideline for miniscrew selection for a predictable clinical outcome. METHODS: The sample consisted of 32 randomly selected adults in the age group of 20 to 25 years. Soft-tissue thickness of the concerned areas was measured intraorally using an A-mode ultrasound transducer probe (Biomedix Optotechnik & Devices, Bangalore, India). Independent t tests, paired t tests, and 1-way analysis of variance with Duncan post hoc tests were used for statistical analysis. RESULTS: The palatal masticatory mucosa was 2 to 3 times thicker than the corresponding buccal attached gingiva in both sexes. The thickness of the palatal masticatory mucosa in the midpalatal region was consistently less than 1 mm (range, 0.7-1 mm). The buccal attached gingiva was comparatively thicker in the maxilla than in the mandible, except for the mandibular molar regions. It also was found that the buccal attached gingiva was thicker in women in the maxillary anterior regions, whereas, the thickness was greater in the maxillary posterior regions in the men. CONCLUSIONS: Evaluating the soft tissue thicknesses before selecting an orthodontic miniscrew can help in providing a definite guide for orthodontists to select an appropriate screw in everyday clinical practice, further enhancing the predictability of miniscrew assisted orthodontics. PMID- 27692424 TI - Morphologic evaluation of dentoalveolar structures of mandibular anterior teeth during augmented corticotomy-assisted decompensation. AB - INTRODUCTION: Our aim in this study was to evaluate the effect of augmented corticotomy on the decompensation pattern of mandibular anterior teeth, alveolar bone, and surrounding periodontal tissues during presurgical orthodontic treatment. METHODS: Thirty skeletal Class III adult patients were divided into 2 groups according to the application of augmented corticotomy labial to the anterior mandibular roots: experimental group (with augmented corticotomy, n = 15) and control group (without augmented corticotomy, n = 15). Lateral cephalograms and cone-beam computed tomography images were taken before orthodontic treatment and before surgery. The measurements included the inclination and position of the mandibular incisors, labial alveolar bone area, vertical alveolar bone height, root length, and alveolar bone thickness at 3 levels surrounding the mandibular central incisors, lateral incisors, and canines. RESULTS: The mandibular incisors were significantly proclined in both groups (P <0.001); however, the labial movement of the incisor tip was greater in the experimental group (P <0.05). Significant vertical alveolar bone loss was observed only in the control group (P <0.001). The middle and lower alveolar thicknesses and labial alveolar bone area increased in the experimental group. In the control group, the upper and middle alveolar thicknesses and labial alveolar bone area decreased significantly. There were no significant differences in dentoalveolar changes between the 3 kinds of anterior teeth in each group, except for root length in the experimental group (P <0.05). CONCLUSIONS: Augmented corticotomy provided a favorable decompensation pattern of the mandibular incisors, preserving the periodontal structures surrounding the mandibular anterior teeth for skeletal Class III patients. PMID- 27692425 TI - Orthodontic treatment and follow-up of a patient with cerebral palsy and spastic quadriplegia. AB - INTRODUCTION: This report describes the clinical orthodontic management of a patient with spastic quadriplegia and cerebral palsy. Guidelines to overcome difficulties encountered during the treatment period are suggested. METHODS: A 13 year-old boy with cerebral palsy and spastic quadriplegia complained of an undesirable oral appearance because of his malocclusion. He had a Class II molar relationship, with severe maxillary and moderate mandibular anterior crowding. Enamel hypoplasia was apparent on all teeth. He had losses of body function and upper extremity function of 70% and 39%, respectively. His physical limitations necessitated a treatment approach that did not rely on patient-dependent appliances. The treatment plan called for maxillary first premolar extractions, mandibular incisor protrusion, and air rotor stripping. RESULTS: The patient's oral function and esthetic appearance were significantly improved. Aligned dental arches with good occlusion were obtained. The patient's self-confidence improved during the treatment period. CONCLUSIONS: Physical appearance can influence personality and social acceptability. Corrective orthodontic treatment for patients with physical handicaps can improve not only oral function, but also self-confidence and self-esteem. PMID- 27692426 TI - Adult skeletal Class II high-angle case treated with a fully customized lingual bracket appliance. AB - To achieve optimum occlusal and facial results in a patient with high-angle maxillary protrusion, it is important to move Point A back with retraction of the anterior teeth and prevent clockwise rotation of the mandible through good vertical control. A woman, aged 42 years 5 months, with a protrusive profile sought lingual orthodontic treatment. She had a skeletal Class II high-angle pattern with maxillary protrusion and mandibular retrusion. The extraction of the 4 first premolars was indicated to correct the problems. The vertical bowing effect, a side effect known to occur with conventional lingual bracket systems owing to torque loss, would preclude adequate retraction of Point A and compromise the facial results. To prevent this issue, a fully customized lingual bracket system with vertical slots for the anterior teeth using ribbon-wise archwires was selected. A midpalatal miniscrew was used to prevent molar extrusion. As a result, the bodily retraction of the maxillary incisors and Point A was achieved, obtaining an attractive facial profile. PMID- 27692427 TI - Forced eruption of impacted maxillary central incisors with severely dilacerated roots. AB - Treatment of impacted dilacerated incisors is challenging for clinicians because of the prominent position of the teeth and the abnormality of their roots. We report on 2 patients who had horizontally upward impacted and severely dilacerated maxillary central incisors. The first patient's root perforated the labial plate without significant resorption, and the second patient's root was resorbed. Both patients were treated by a surgical-orthodontic approach, and the crowns of the impacted teeth were brought into the arches by closed forced eruption. Therefore, if impacted teeth have dilacerated roots, patients should be told of the possibility of root resorption. PMID- 27692428 TI - New algorithm for semiautomatic segmentation of nasal cavity and pharyngeal airway in comparison with manual segmentation using cone-beam computed tomography. AB - INTRODUCTION: Our objectives were to assess reliability, validity, and time efficiency of semiautomatic segmentation using Segura software of the nasal and pharyngeal airways, against manual segmentation with point-based analysis with color mapping. METHODS: Pharyngeal and nasal airways from 10 cone-beam computed tomography image sets were segmented manually and semiautomatically using Segura (University of Alberta, Edmonton, Alberta, Canada). To test intraexaminer and interexaminer reliabilities, semiautomatic segmentation was repeated 3 times by 1 examiner and then by 3 examiners. In addition to volume and surface area, point based analysis was completed to assess the reconstructed 3-dimensional models from Segura against manual segmentation. The times of both methods of segmentation were also recorded to assess time efficiency. RESULTS: The reliability and validity of Segura were excellent (intraclass correlation coefficient, >0.9 for volume and surface area). Part analysis showed small differences between the Segura and manually segmented 3-dimensional models (greatest difference did not exceed 4.3 mm). Time of segmentation using Segura was significantly shorter than that for manual segmentation, 49 +/- 11.0 vs 109 +/- 9.4 minutes (P <0.001). CONCLUSIONS: Semiautomatic segmentation of the pharyngeal and nasal airways using Segura was found to be reliable, valid, and time efficient. Part analysis with color mapping was the key to explaining differences in upper airway volume and provides meaningful and clinically relevant analysis of 3-dimensional changes.

AB - Ocean acidification and rising seawater temperature are environmental stressors resulting from the continuous increase of the atmospheric CO2 concentration due to anthropogenic activities. As a consequence, marine fish are expected to undergo conditions outside of their tolerance range, leading to physiological challenges with possible detrimental implications. Our research group has previously shown that exposure to elevated CO2 modulated the immune system of the Atlantic halibut. To further investigate this finding, we analysed non-specific immune components in blood plasma of Atlantic halibut (Hippoglossus hippoglossus) juveniles acclimated to six different temperatures (5, 10, 12, 14, 16 and 18 degrees C), and to water pH of 8.0 (control) or 7.6 (predicted for year 2100) for three months. Plasma ions (K+, Na+, Ca++, Cl-) and lactate concentrations were also measured. The analysis of plasma ions did not show any trends related to temperature or CO2 exposure, and the majority of the experimental fish were able to maintain ionic balance. The results show that both innate immune components (lysozyme and alternative complement system) had increased activities in response to elevated CO2, representing a CO2-related impact on the halibut's immune system. The increased activity of lysozyme and complement system is possibly part of the acclimatization process, and might be protective. PMID- 27692431 TI - The Chromatin Landscape of Cellular Senescence. AB - Cellular senescence, an irreversible growth arrest triggered by a variety of stressors, plays important roles in normal physiology and tumor suppression, but accumulation of senescent cells with age contributes to the functional decline of tissues. Senescent cells undergo dramatic alterations to their chromatin landscape that affect genome accessibility and their transcriptional program. These include the loss of DNA-nuclear lamina interactions, the distension of centromeres, and changes in chromatin composition that can lead to the activation of retrotransposons. Here we discuss these findings, as well as recent advances in microscopy and genomics that have revealed the importance of the higher-order spatial organization of the genome in defining and maintaining the senescent state. PMID- 27692434 TI - Utility of anti-factor Xa monitoring in surgical patients receiving prophylactic doses of enoxaparin for venous thromboembolism prophylaxis. AB - BACKGROUND: Between 2% and 10% of the highest risk surgery, patients have a "breakthrough" venous thromboembolism (VTE) event despite receipt of chemoprophylaxis. The goals of this review are to summarize how patient-level factors may predict enoxaparin metabolism and how alterations in enoxaparin dose magnitude and frequency affect both anti-factor Xa (aFXa) levels and downstream VTE events. DATA SOURCES: Relevant articles were identified on PubMed. Fixed-dose prophylaxis provides inadequate enoxaparin prophylaxis for most surgical patients based on anti-factor Xa levels. Inadequate enoxaparin dosing has been correlated with both asymptomatic and symptomatic VTE events. Patient-level factors such as gross weight and extent of injury predict enoxaparin metabolism. Weight-based or weight-tiered dosing regimens-and real-time dose adjustment based on anti-factor Xa levels-allow an increased proportion of patients to have in-range anti-factor Xa levels. CONCLUSIONS: Inadequate enoxaparin dosing may explain why some patients have VTE despite enoxaparin prophylaxis. Ongoing research in the utility of weight-based or anti-factor Xa level driven enoxaparin dosing and dose adjustment is reasonable. PMID- 27692433 TI - Moderating effects of immunosuppressive medications and risk factors for post operative joint infection following total joint arthroplasty in patients with rheumatoid arthritis or osteoarthritis. AB - OBJECTIVE: Inconclusive findings about infection risks, importantly the use of immunosuppressive medications in patients who have undergone large-joint total joint arthroplasty, challenge efforts to provide evidence-based perioperative total joint arthroplasty recommendations to improve surgical outcomes. Thus, the aim of this study was to describe risk factors for developing a post-operative infection in patients undergoing TJA of a large joint (total hip arthroplasty, total knee arthroplasty, or total shoulder arthroplasty) by identifying clinical and demographic factors, including the use of high-risk medications (i.e., prednisone and immunosuppressive medications) and diagnoses [i.e., rheumatoid arthritis (RA), osteoarthritis (OA), gout, obesity, and diabetes mellitus] that are linked to infection status, controlling for length of follow-up. METHODS: A retrospective, case-control study (N = 2212) using de-identified patient health claims information from a commercially insured, U.S. dataset representing 15 million patients annually (from January 1, 2007 to December 31, 2009) was conducted. Descriptive statistics, t-test, chi-square test, Fisher's exact test, and multivariate logistic regression were used. RESULTS: Male gender (OR = 1.42, p < 0.001), diagnosis of RA (OR = 1.47, p = 0.031), diabetes mellitus (OR = 1.38, p = 0.001), obesity (OR = 1.66, p < 0.001) or gout (OR = 1.95, p = 0.001), and a prescription for prednisone (OR = 1.59, p < 0.001) predicted a post-operative infection following total joint arthroplasty. Persons with post-operative joint infections were significantly more likely to be prescribed allopurinol (p = 0.002) and colchicine (p = 0.006); no significant difference was found for the use of specific disease-modifying anti-rheumatic drugs and TNF-alpha inhibitors. CONCLUSION: High-risk, post-operative joint infection groups were identified allowing for precautionary clinical measures to be taken. PMID- 27692435 TI - The milk we drink, food for thought. PMID- 27692436 TI - New automated antimullerian hormone assays are more reliable than the manual assay in patients with reduced antral follicle count. AB - OBJECTIVE: To compare the strength of the relationship between antral follicle count (AFC) and serum antimullerian hormone (AMH) concentrations obtained with two automated and one manual AMH assays in three different AFC populations. DESIGN: Prospective cohort study. SETTING: University-affiliated IVF-ET center. PATIENT(S): Frozen-thawed serum samples of 211 assisted conception candidates, aged 24-43 years. INTERVENTION(S): Serum AMH was measured using one manual (AMH Gen II) and two fully automated (Access AMH and Elecsys AMH) assays. Antral follicle count was performed under strictly standardized conditions and sorted into three groups according to tercile values: low AFC (3-12 follicles; n = 73), intermediate AFC (13-20 follicles; n = 65), and high AFC (21-84 follicles; n = 73). MAIN OUTCOME MEASURE(S): Strength of correlation between AMH levels and AFC. RESULT(S): Overall, AMH levels were lower with Access AMH (-16%) and Elecsys AMH (-20%) than with AMH Gen II. Remarkably, the strength of correlations between AFC and circulating AMH levels was the same with the three assays (r = 0.83). Yet in the low AFC group, serum AMH levels obtained by Access AMH and Elecsys AMH showed a stronger correlation with AFC (r = 0.63 and r = 0.65, respectively) than the AMH Gen II (r = 0.52), a phenomenon that was not observed in the remaining AFC groups. CONCLUSION(S): As compared with conventional AMH Gen II assay results, [1] serum AMH concentrations were -16% and -20% lower with Access AMH and Elecsys AMH, respectively; and [2] automated assays were more strongly correlated to AFC in the subset of patients with reduced follicle count. PMID- 27692437 TI - Why do euploid embryos miscarry? A case-control study comparing the rate of aneuploidy within presumed euploid embryos that resulted in miscarriage or live birth using next-generation sequencing. AB - OBJECTIVE: To determine whether undetected aneuploidy contributes to pregnancy loss after transfer of euploid embryos that have undergone array comparative genomic hybridization (aCGH). DESIGN: Case-control study. SETTING: University based fertility center. PATIENT(S): Cases included 38 patients who underwent frozen euploid ET as determined by aCGH, resulting in miscarriage. Controls included 38 patients who underwent frozen euploid ET as determined by aCGH, resulting in a live birth. INTERVENTION(S): Next-generation sequencing (NGS) protocols were internally validated. Saved amplified DNA samples from the blastocyst trophectoderm biopsies previously diagnosed as euploid by aCGH were reanalyzed using NGS. Cytogenetic reports of the products of conception for 20 of the pregnancies resulting in miscarriage were available for comparison. MAIN OUTCOME MEASURE(S): The incidence of aneuploidy and mosaicism using NGS within embryos resulting in miscarriage and live birth. RESULT(S): Of euploid embryos analyzed by aCGH resulting in miscarriage, 31.6% were mosaic and 5.2% were polyploid by NGS. The rate of chromosomal abnormalities was significantly higher in embryos resulting in miscarriage (36.8%) than in those resulting in live births (15.8%). The rate of mosaicism was twice as high among embryos resulting in miscarriage than those resulting in live birth, but this was not statistically significant. Next-generation sequencing detected more cases of mosaicism than cytogenetic analysis of products of conception. CONCLUSION(S): Undetected aneuploidy may increase the risk of first trimester pregnancy loss. Next generation sequencing may detect mosaicism and triploidy more frequently than aCGH, which could help to identify embryos at high risk of miscarriage. Mosaic embryos, however, should not be discarded as some can result in live births. PMID- 27692439 TI - CVD-grown monolayer graphene induces osteogenic but not odontoblastic differentiation of dental pulp stem cells. AB - OBJECTIVE: The objective was to investigate the potential of graphene (Gp) to induce odontogenic and osteogenic differentiation in dental pulp stem cells (DPSC). METHODS: Gp was produced by chemical vapor deposition. DPSC were seeded on Gp or glass (Gl). Cells were maintained in culture medium for 28 days. Every two days, culture medium from Gp was used to treat cells on Gl and vice versa. Mineralization and differentiation of DPSC on all substrates were evaluated after 14 and 28 days by alizarin red S staining, qPCR, immunofluorescence and FACS. Statistics were performed with two-way ANOVA and multiple comparisons were performed using Tukey's post hoc test at a pre-set significance level of 5%. RESULTS: After 14 and 28 days, Gp induced higher levels of mineralization as compared to Gl. Odontoblastic genes (MSX-1, PAX and DMP) were down-regulated and osteogenic genes and proteins (RUNX2, COL and OCN) were significantly upregulated on Gp comparing to Gl (p<0.05 for all cases). Medium from Gp induced downregulation of odontoblastic genes and increased bone-related gene and protein on Gl. SIGNIFICANCE: Graphene induced osteogenic and not odontoblastic differentiation of DPSC without the use of chemical inducers for osteogenesis. Graphene has the potential to be used as a substrate for craniofacial bone tissue engineering research. PMID- 27692438 TI - Bovine tooth is a substitute for human tooth on bond strength studies: A systematic review and meta-analysis of in vitro studies. AB - OBJECTIVES: This study aimed to systematically review the literature to compare the bond strength values achieved from human and bovine teeth of in vitro studies. DATA AND SOURCE: The PubMed/MEDLINE, ISI Web of Science and Scopus electronic databases were searched to select laboratorial studies that evaluated adhesive systems bond strength to human and bovine teeth. No publication year or language restriction was considered. STUDY SELECTION: From 1,285 potentially eligible studies, 15 were selected for full-text analysis, 11 were included in the systematic review and 9 in the meta-analysis. Two authors independently selected the studies, extracted the data and assessed the risk of bias. Mean differences were obtained by comparing bond strength values between human and bovine teeth (overall analysis), and considering enamel and dentin separately (subgroups analysis). Statistical analysis was performed using RevMan5.1, with random effects model, at a significance level of p=0.05. RESULTS: No significant difference was found between human and bovine teeth (p=0.35), either for enamel (p=0.07) or for dentin (p=0.93) substrates. Low to moderate heterogeneity was found on the meta-analysis. All included studies in the systematic review scored between medium and high risk of bias. CONCLUSIONS: Bovine teeth can be a reliable substitute for human ones on bond strength studies of adhesive systems to both enamel and dentin substrates. PMID- 27692441 TI - Successful Hemodialysis Arteriovenous Fistula Creation in a Patient With Continuous-Flow Left Ventricular Assist Device Support. AB - Heart failure necessitating left ventricular assist device (LVAD) support can lead to kidney failure requiring dialysis. Some of these patients may require long-term hemodialysis (HD). Optimal vascular access for a patient on long-term HD therapy with an LVAD remains a complex issue. The majority of LVADs are of the continuous-flow type, and it has been theorized that native arteriovenous fistula maturation may be impaired in a setting of decreased pulsatile arterial flow. We describe a case of successful creation and use of an arteriovenous fistula in an HD-dependent patient with a continuous-flow LVAD.

AB - OBJECTIVE: To assess the impact of gender upon the prognosis and medical care in a regional acute ST-elevation myocardial infarction management network. DESIGN: An observational study was made of consecutive patients entered in a prospective database. SCOPE: The Catalan acute ST-elevation myocardial infarction management network. PATIENTS: Patients treated between January 2010 and December 2011. INTERVENTIONS: Primary angioplasty, thrombolysis or conservative management. VARIABLES OF INTEREST: Time intervals, proportion and type of reperfusion, overall mortality, and in-hospital complication and overall mortality at 30 days and one year were compared in relation to gender. RESULTS: Of the 5,831 patients attended by the myocardial infarction network, 4,380 had a diagnosis of acute ST elevation myocardial infarction, and 961 (21.9%) were women. Women were older (69.8+/-13.4 vs. 60.6+/-12.8 years; P<.001), had a higher prevalence of diabetes (27.1 vs. 18.1%, P<.001), Killip class>I (24.9 vs. 17.3%; P<.001) and no reperfusion (8.8 vs. 5.2%; P<.001) versus men. In addition, women had greater delays in medical care (first medical contact-to-balloon: 132 vs. 122min; P<.001, and symptoms onset-to-balloon: 236 vs. 210min; P<.001). Women presented higher percentages of overall in-hospital complications (20.6 vs. 17.4%; P=.031), in hospital mortality (4.8 vs. 2.6%; P=.001), 30-day mortality (9.1 vs. 4.5%; P<.001) and one-year mortality (14.0 vs. 8.3%; P<.001) versus men. Nevertheless, after multivariate adjustment, no gender differences in 30-day and one-year mortality were observed. CONCLUSIONS: Despite a higher risk profile and poorer medical management, women present similar 30-day and one-year outcomes as their male counterparts in the context of the myocardial infarction management network. PMID- 27692442 TI - Hypophosphatemia in Users of Cannabis. AB - As cannabis use has legalized for medical and recreational use in several states, the medical community has become more aware of the drug's potential toxicities. First described in 2004, cannabinoid hyperemesis syndrome is increasingly recognized as a cause of hospitalization among drug users. However, little information is available in the medical literature regarding electrolyte abnormalities in this syndrome. Between 2011 and 2014, six men were treated for cannabinoid hyperemesis syndrome at the Veterans Affairs Medical Center in San Diego, CA, and found to have significant hypophosphatemia (phosphate range, <1 1.3mg/dL). The 6 cases are presented here and possible causes of hypophosphatemia are discussed. In 3 patients, serum phosphate levels normalized spontaneously within hours, suggesting redistribution of phosphate as a potential mechanism. Hyperventilation, which can lead to phosphate redistribution, was observed in 4 of the 6 individuals and may have contributed. Hypophosphatemia is a presenting feature of cannabinoid hyperemesis syndrome in some patients.

PMID- 27692444 TI - Basics of Confocal Microscopy and the Complexity of Diagnosing Skin Tumors: New Imaging Tools in Clinical Practice, Diagnostic Workflows, Cost-Estimate, and New Trends. AB - The use of reflectance confocal microscopy (RCM) and other noninvasive imaging devices can potentially streamline clinical care, leading to more precise and efficient management of skin cancer. This article explores the potential role of RCM in cutaneous oncology, as an adjunct to more established techniques of detecting and monitoring for skin cancer, such as dermoscopy and total body photography. Discussed are current barriers to the adoption of RCM, diagnostic workflows and standards of care in the United States and Europe, and medicolegal issues. The potential role of RCM and other similar technological innovations in the enhancement of dermatologic care is evaluated. PMID- 27692445 TI - Opening a Window into Living Tissue: Histopathologic Features of Confocal Microscopic Findings in Skin Tumors. AB - The knowledge of histopathology and in vivo reflectance confocal microscopy correlation has several potential applications. Reflectance confocal microscopy can be performed in all skin tumors, and in this article, the most common histopathologic features of confocal microscopic findings in melanocytic skin tumors and nonmelanocytic skin tumors are described. PMID- 27692446 TI - Discriminating Nevi from Melanomas: Clues and Pitfalls. AB - Reflectance confocal microscopy (RCM) together with dermoscopy enables improved differentiation of melanomas from most nevi. The resulting high sensitivity for detecting melanoma with RCM is complemented by a concomitant increased specificity, which results in the reduction of unnecessary biopsies of nevi. Although RCM can achieve high diagnostic accuracy for early melanoma detection, false-negative and false-positive cases of melanoma are occasionally encountered. This article reviews the essential clues and pitfalls for the diagnosis of melanoma via RCM and highlights the importance of evaluating RCM findings in light of the clinical scenario and dermoscopic features. PMID- 27692447 TI - Melanomas. AB - Melanomas are a wide range of tumors that differ in their epidemiology, morphology, genetic profile, and biological behavior. They can be grouped as superficial spreading melanoma, lentigo maligna, and nodular melanoma. Reflectance confocal microscopy is useful for the evaluation of skin lesions that are dermoscopically doubtful by increasing diagnostic accuracy and specificity. This article provides a comprehensive overview of the different confocal main morphologies of distinct melanoma types as a function of the anatomic location of the tumor. PMID- 27692448 TI - Lentigo Maligna, Macules of the Face, and Lesions on Sun-Damaged Skin: Confocal Makes the Difference. AB - Distinguishing lentigo maligna (LM) and lentigo maligna melanoma (LMM) from background pigmented non-melanoma lesions is challenging. The field of solar damage can obscure clinical assessment, and diagnostic ambiguities are created due to the overlap of the clinical features of LM with other benign lesions. Moreover, margin assessment on histology is limited by the resemblance between melanocytic hyperplasia of actinically damaged skin and scattered atypical melanocytes of LM/LMM. Dermoscopy has made a significant contribution but is often not sufficient for diagnosis and margin assessment. Confocal microscopy has become an important complementary tool in enhancing the management of these complex lesions. PMID- 27692449 TI - Glowing in the Dark: Use of Confocal Microscopy in Dark Pigmented Lesions. AB - Reflectance confocal microscopy patterns and structures of clinically dark lesions are described. Because many of the dark lesions have melanin in superficial skin layers these lesions show great semiology by confocal. Limitations and pitfalls of reflectance confocal microscopy in clinically dark lesions are also detailed. PMID- 27692450 TI - Enlightening the Pink: Use of Confocal Microscopy in Pink Lesions. AB - Solitary pink lesions can pose a particular challenge to dermatologists because they may be almost or completely featureless clinically and dermoscopically, previously requiring biopsy to exclude malignancy. However, these lesions usually are not particularly challenging histopathologically. Thus, the incorporation of in vivo reflectance confocal microscopy into the clinical practice, which allows for noninvasive examination of the skin at the cellular level revealing features previously seen only on histopathology, is particularly useful for this subset of clinically difficult lesions. PMID- 27692451 TI - Shining into the White: The Spectrum of Epithelial Tumors from Actinic Keratosis to Squamous Cell Carcinoma. AB - Actinic keratosis, Bowen disease, and invasive squamous cell carcinoma represent different steps within the disease continuum of squamous neoplasia. Although these stages of squamous neoplasia share common findings, reflectance confocal microscopy may be applied for their differentiation and distinction from other benign or malignant lesions. Hyperkeratosis represents the most important limitation in the evaluation of squamous neoplasia as it may impair the analysis of deeper epidermal and dermal structures significantly. PMID- 27692452 TI - Application of Handheld Confocal Microscopy for Skin Cancer Diagnosis: Advantages and Limitations Compared with the Wide-Probe Confocal. AB - The clinical diagnosis of tumors on the curved surfaces of the face, around the eyes, and on the mucosal surfaces can be difficult, while biopsies and excisions can have functional and aesthetic consequences. To avoid unnecessary surgery, clinicians have been aiming to attain accurate noninvasive diagnosis of lesions at these sites. However, acquisition of high-quality images with dermoscopy and with traditional wide-probe reflectance confocal microscopy (WP-RCM) have been hampered with technical difficulties. This article discusses the technical parameters of the handheld reflectance confocal microscope and discusses its advantages and limitations compared with the WP-RCM.

Three groups of optical histology have been described: psoriasiform, spongiotic, and interface dermatitis. In a multicenter study, RCM patterns of spongiotic, hyperkeratotic, and interface dermatitis have been analyzed and an algorithmic method of analysis for fast application in the clinical setting based on a multivariate analysis has been proposed. A tree decision diagram has been also established. PMID- 27692456 TI - Telediagnosis with Confocal Microscopy: A Reality or a Dream? AB - Reflectance confocal microscopy (RCM) is becoming more popular among dermatologists aiming to improve their bedside diagnostic accuracy and reduce unnecessary removal of benign cutaneous lesions. With increased interest in the field, limitation of experts, and dedicated training programs, telemedicine application to RCM (teleconfocal) helps to connect patients with experts at a distance. Diagnostic accuracy of store-and-forward telemedicine review of RCM images, patient safety, and cost-effectiveness are important considerations for proper acceptance and usage of the technology in the medical community. PMID- 27692455 TI - In Vivo and Ex Vivo Confocal Microscopy for Dermatologic and Mohs Surgeons. AB - Confocal microscopy is a modern imaging device that has been extensively applied in skin oncology. More specifically, for tumor margin assessment, it has been used in two modalities: reflectance mode (in vivo on skin patient) and fluorescence mode (on freshly excised specimen). Although in vivo reflectance confocal microscopy is an add-on tool for lentigo maligna mapping, fluorescence confocal microscopy is far superior for basal cell carcinoma and squamous cell carcinoma margin assessment in the Mohs setting.

AB - Reflectance confocal microscopy (RCM) allows the evaluation with superb accuracy of some skin tumors before, during, and after treatment. In clinical trials RCM has been shown to provide useful information for evaluation of efficacy of topical or systemic medication. With the recent introduction of handheld RCM a fast examination of the tumor can be done in minutes. In patients treated with surgery RCM plays a unique role to precisely map margins of the tumor in the skin surface and for the detection of subclinical recurrences.

PMID- 27692462 TI - Early-Term Birth in Single-Ventricle Congenital Heart Disease After the Fontan Procedure: Neurodevelopmental and Psychiatric Outcomes. AB - OBJECTIVES: To investigate the long-term impact of early-term birth (37-38 weeks' gestation) relative to full-term birth (>=39 weeks' gestation) on neurodevelopmental and psychiatric outcomes in adolescents with single-ventricle congenital heart disease (CHD). STUDY DESIGN: This cross-sectional cohort study analyzed retrospective medical records from full term adolescents with single ventricle CHD who underwent the Fontan procedure. Participants underwent neurodevelopmental and psychiatric evaluations, as well as structural brain magnetic resonance imaging. Early-term born adolescents were compared with full term born adolescents using regression models with adjustments for family social status, birth weight, and genetic abnormality status. Medical and demographic risk factors were examined as well. RESULTS: Compared with the full-term group (n = 100), adolescents born early term (n = 33) scored significantly worse on daily life executive functions, as measured by the Behavior Rating Inventory of Executive Function parent-report (mean scores: early term, 62.0 +/- 10.9; full term, 55.6 +/- 12.2; P = .009) and self-report (P = .02) composites. Adolescents born early term were more likely than those born full term to have a lifetime attention-deficit/hyperactivity disorder (ADHD) diagnosis (early term, 55%; full term, 26%; P = .001). The early-term group also displayed greater psychiatric symptom severity, as indicated by the clinician-reported Brief Psychiatric Rating Scale (mean score: early term, 16.1 +/- 8.6; full-term, 12.5 +/- 8.2; P = .007). CONCLUSION: Early-term birth is associated with greater prevalence of executive dysfunction, ADHD diagnosis, and psychiatric problems in adolescents with single ventricle CHD. Early-term birth should be included as a potential risk factor in the algorithm for closer developmental surveillance in CHD. PMID- 27692464 TI - Long-Term Outcome of Classic and Incomplete PFAPA (Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Adenitis) Syndrome after Tonsillectomy. AB - OBJECTIVE: To compare the effectiveness of tonsillectomy and the long-term outcome of periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome in patients fulfilling the classic diagnostic criteria and in those with regularly recurring fever as the only symptom or with onset of symptoms after age 5 years or both. STUDY DESIGN: We reviewed the medical records of 3852 children who underwent tonsillectomy between 1990 and 2007 and identified 108 children who did so because of regularly recurring fevers. The patients were invited to an outpatient visit and were classified into 2 groups: those who met (N = 58) and those who did not meet (N = 50) Thomas diagnostic criteria. We then compared the clinical profile and outcome of PFAPA symptoms after tonsillectomy between the 2 groups. RESULTS: In the group that met Thomas criteria, 97% (56/58) had complete resolution of fever episodes after tonsillectomy; in the group that did not meet Thomas criteria (50/50) had complete resolution of fever episodes after tonsillectomy (P = .25). The clinical profile of the periodic fevers and the occurrence of other illnesses during follow-up were similar in both groups. Thomas criteria identified 56 of 106 patients responding to tonsillectomy. CONCLUSIONS: Tonsillectomy was an effective treatment for patients with regularly recurring fever episodes who failed to meet the classic Thomas criteria. We suggest that PFAPA syndrome should be suspected and tonsillectomy considered in children with a late onset of symptoms (>5 years of age) or when fever is the only symptom during the episodes. PMID- 27692461 TI - Epigenetic Regulation of the Thermogenic Adipose Program. AB - In contrast to white adipose tissue (WAT), which stores energy in the form of triglycerides, brown adipose tissue (BAT) dissipates energy by producing heat to maintain body temperature by burning glucose and fatty acids in a process called adaptive thermogenesis. The presence of an inducible thermogenic adipose tissue, and its beneficial effects for maintaining body weight and glucose and lipid homeostasis, has raised intense interest in understanding the regulation of thermogenesis. Elucidating the regulatory mechanisms underlying the thermogenic adipose program may provide excellent targets for therapeutics against obesity and diabetes. Here we review recent research on the role of epigenetics in the thermogenic gene program, focusing on DNA methylation and histone modifications. PMID- 27692463 TI - Variability in Management of First Cerebrospinal Fluid Shunt Infection: A Prospective Multi-Institutional Observational Cohort Study. AB - OBJECTIVES: To describe the variation in approaches to surgical and antibiotic treatment for first cerebrospinal fluid (CSF) shunt infection and adherence to Infectious Diseases Society of America (IDSA) guidelines. STUDY DESIGN: We conducted a prospective cohort study of children undergoing treatment for first CSF infection at 7 Hydrocephalus Clinical Research Network hospitals from April 2008 through December 2012. Univariate analyses were performed to describe the study population. RESULTS: A total of 151 children underwent treatment for first CSF shunt-related infection. Most children had undergone initial CSF shunt placement before the age of 6 months (n = 98, 65%). Median time to infection after shunt surgery was 28 days (IQR 15-52 days). Surgical management was most often shunt removal with interim external ventricular drain placement, followed by new shunt insertion (n = 122, 81%). Median time from first negative CSF culture to final surgical procedure was 14 days (IQR 10-21 days). Median duration of intravenous (IV) antibiotic use duration was 19 days (IQR 12-28 days). For 84 infections addressed by IDSA guidelines, 7 (8%) met guidelines and 61 (73%) had longer duration of IV antibiotic use than recommended. CONCLUSIONS: Surgical treatment for infection frequently adheres to IDSA guidelines of shunt removal with external ventricular drain placement followed by new shunt insertion. However, duration of IV antibiotic use in CSF shunt infection treatment was consistently longer than recommended by the 2004 IDSA guidelines. PMID- 27692465 TI - Response. PMID- 27692466 TI - Analytic cognitive style predicts paranormal explanations of anomalous experiences but not the experiences themselves: Implications for cognitive theories of delusions. AB - BACKGROUND AND OBJECTIVES: It has been proposed that delusional beliefs are attempts to explain anomalous experiences. Why, then, do anomalous experiences induce delusions in some people but not in others? One possibility is that people with delusions have reasoning biases that result in them failing to reject implausible candidate explanations for anomalous experiences. We examine this hypothesis by studying paranormal interpretations of anomalous experiences. METHODS: We examined whether analytic cognitive style (i.e. the willingness or disposition to critically evaluate outputs from intuitive processing and engage in effortful analytic processing) predicted anomalous experiences and paranormal explanations for these experiences after controlling for demographic variables and cognitive ability. RESULTS: Analytic cognitive style predicted paranormal explanations for anomalous experiences, but not the anomalous experiences themselves. LIMITATIONS: We did not study clinical delusions. Our attempts to control for cognitive ability may have been inadequate. Our sample was predominantly students. CONCLUSIONS: Limited analytic cognitive style might contribute to the interpretation of anomalous experiences in terms of delusional beliefs. PMID- 27692468 TI - Doing something about physician burnout. PMID- 27692467 TI - Regional variation in patient selection and treatment for lower extremity vascular disease in the Vascular Quality Initiative. AB - OBJECTIVE: Prior studies on the cause and effect of surgical variation have been limited by utilization of administrative data. The Vascular Quality Initiative (VQI), a robust national clinical registry, provides anatomic and perioperative details allowing a more robust analysis of variation in surgical practice. METHODS: The VQI was used to identify all patients undergoing infrainguinal open bypass or endovascular intervention from 2009 to 2014. Asymptomatic patients were excluded. The 16 regional groups of the VQI were used to compare variation in patient selection, operative indication, technical approach, and process measures. chi2 analysis was used to assess for differences across regions where appropriate. RESULTS: A total of 52,373 interventions were included (31%). Of the 16,145 bypasses, 5% were performed for asymptomatic disease, 26% for claudication, 56% for chronic limb-threatening ischemia (CLI) (61% of these for tissue loss), and 13% for acute limb-threatening ischemia. Of the 35,338 endovascular procedures, 4% were for asymptomatic disease, 40% for claudication, 46% for CLI (73% tissue loss), and 12% for acute limb-threatening ischemia. Potentially unwarranted variation included proportion of prosthetic conduit for infrapopliteal bypass in claudication (13%-41%, median, 29%; P < .001), isolated tibial endovascular intervention for claudication (0.0%-5.0%, median, 3.0%; P < .001), discharge on antiplatelet and statin (bypass: 62%-84%; P < .001; endovascular: 63%-89%; P < .001), and ultrasound guidance for percutaneous access (claudication: range, 7%-60%; P < .001; CLI: 5%-65%; P < .001). Notable areas needing further research with significant variation include proportion of CLI vs claudication treated by bypass (38%-71%; P < .001) and endovascular intervention (28%-63%; P < .001), and use of closure devices in percutaneous access (claudication; 26%-76%; P < .001; CLI: 30%-78%; P < .001). CONCLUSIONS: Significant variation exists both in areas where evidence exists for best practice and, therefore, potentially unwarranted variation, and in areas of clinical ambiguity. Quality improvement efforts should be focused on reducing unwarranted variation. Further research should be directed at identifying best practice where no established guidelines and high variation exists. PMID- 27692469 TI - Interventions to prevent and reduce physician burnout: a systematic review and meta-analysis. AB - BACKGROUND: Physician burnout has reached epidemic levels, as documented in national studies of both physicians in training and practising physicians. The consequences are negative effects on patient care, professionalism, physicians' own care and safety, and the viability of health-care systems. A more complete understanding than at present of the quality and outcomes of the literature on approaches to prevent and reduce burnout is necessary. METHODS: In this systematic review and meta-analysis, we searched MEDLINE, Embase, PsycINFO, Scopus, Web of Science, and the Education Resources Information Center from inception to Jan 15, 2016, for studies of interventions to prevent and reduce physician burnout, including single-arm pre-post comparison studies. We required studies to provide physician-specific burnout data using burnout measures with validity support from commonly accepted sources of evidence. We excluded studies of medical students and non-physician health-care providers. We considered potential eligibility of the abstracts and extracted data from eligible studies using a standardised form. Outcomes were changes in overall burnout, emotional exhaustion score (and high emotional exhaustion), and depersonalisation score (and high depersonalisation). We used random-effects models to calculate pooled mean difference estimates for changes in each outcome. FINDINGS: We identified 2617 articles, of which 15 randomised trials including 716 physicians and 37 cohort studies including 2914 physicians met inclusion criteria. Overall burnout decreased from 54% to 44% (difference 10% [95% CI 5-14]; p<0.0001; I2=15%; 14 studies), emotional exhaustion score decreased from 23.82 points to 21.17 points (2.65 points [1.67-3.64]; p<0.0001; I2=82%; 40 studies), and depersonalisation score decreased from 9.05 to 8.41 (0.64 points [0.15-1.14]; p=0.01; I2=58%; 36 studies). High emotional exhaustion decreased from 38% to 24% (14% [11-18]; p<0.0001; I2=0%; 21 studies) and high depersonalisation decreased from 38% to 34% (4% [0-8]; p=0.04; I2=0%; 16 studies). INTERPRETATION: The literature indicates that both individual-focused and structural or organisational strategies can result in clinically meaningful reductions in burnout among physicians. Further research is needed to establish which interventions are most effective in specific populations, as well as how individual and organisational solutions might be combined to deliver even greater improvements in physician wellbeing than those achieved with individual solutions.

AB - In the host a diverse collection of endogenous danger signals is constantly generated consisting of waste material as protein aggregates or crystalline materials that are recognized and handled by soluble pattern recognition receptors and phagocytic cells of the innate immune system. These signals may under certain circumstances drive processes leading to adverse inflammation. One example is cholesterol crystals (CC) that accumulate in the vessel wall during early phases of atherogenesis and represent an important endogenous danger signal promoting inflammation. CC is recognized by the lectin- and classical pathways of the complement system resulting in activation of C3 and C5 with release of inflammatory mediators like the potent C5a fragment. Complement activation by CC leads to crosstalk with the NLRP3 inflammasome-caspase-1 pathway and production of IL-1beta. Neutralization of IL-1beta may have beneficial effects on atherosclerosis and a large clinical trial with an IL-1beta inhibitor is currently in progress (the CANTOS study). However, upstream inhibition of CC induced inflammation by using a complement inhibitor may be more efficient in treating atherosclerosis since this will block initiation of inflammation processes before downstream release of cytokines including IL-1beta. Another therapeutic candidate can be broad-acting 2-hydroxypropyl-beta-cyclodextrin, a compound that targets several mechanisms such as cholesterol efflux, complement gene expression, and the NLRP3 pathway. In summary, emerging evidence show that complement is a key upstream player in the pathophysiology of atherosclerosis and that therapy aiming at inhibiting complement could be effective in controlling atherosclerosis. PMID- 27692471 TI - Seasonal exports and drivers of dissolved inorganic and organic carbon, carbon dioxide, methane and delta13C signatures in a subtropical river network. AB - Riverine systems act as important aquatic conduits for carbon transportation between atmospheric, terrestrial and oceanic pools, yet the magnitude of these exports remain poorly constrained. Interconnected creek and river sites (n=28) were sampled on a quarterly basis in three subcatchments of the subtropical Richmond River Catchment (Australia) to investigate spatial and temporal dynamics of dissolved inorganic carbon (DIC), dissolved organic carbon (DOC), carbon dioxide (CO2), methane (CH4), and carbon stable isotope ratios (delta13C). The study site is an area of high interest due to potential unconventional gas (coal seam gas or coal bed methane) development. DIC exports were driven by groundwater discharge with a small contribution by in situ DOC remineralization. The DIC exports showed seasonal differences ranging from 0.10 to 0.27mmolm-2catchmentd-1 (annual average 0.17mmolm-2catchmentd-1) and peaked during winter when surface water discharge was highest. DOC exports (sourced from terrestrial organic matter) had an annual average 0.07mmolm-2catchmentd-1 and were 1 to 2 orders of magnitude higher during winter compared to spring and summer. CO2 evasion rates (annual average of 347mmolm-2water aread-1) were ~2.5 fold higher during winter compared to spring. Methane was always supersaturated (0.19 to 62.13MUM), resulting from groundwater discharge and stream-bed methanogenesis. Methane evasion was highly variable across the seasons with an annual average of 3.05mmolm-2water aread-1. During drier conditions, stable isotopes implied enhanced CH4 oxidation. Overall, carbon losses from the catchment were dominated by CO2 evasion (60%) followed by DIC exports (30%), DOC exports (9%) and CH4 evasion (<1%). Our results demonstrated broad catchment scale spatial and temporal variability in carbon dynamics, and that groundwater discharge and rain events controlled carbon exports. PMID- 27692472 TI - Application of the Multimedia Urban Model to estimate the emissions and environmental fate of PAHs in Tarragona County, Catalonia, Spain. AB - The Multimedia Urban Model (MUM-Fate) was used to estimate the emissions, fate and transport of polycyclic aromatic hydrocarbons (PAHs) in Tarragona County, Catalonia, Spain, where the largest chemical/petrochemical industrial complex of Southern Europe is located. MUM-Fate is a Level III steady-state fugacity model consisting of seven bulk media compartments (lower and upper air, surface water, sediment, soil, vegetation, and an organic film that coats impervious surfaces). The model was parameterized according to environmental conditions in Tarragona County, and used to back-calculate emissions from measured air concentrations of naphthalene, anthracene, phenanthrene, fluoranthene, pyrene, and benzo[a]pyrene. Modelled results in soils were within the range reported for measured concentrations. Estimated emissions of ?6PAH were 42ty-1, with phenanthrene having the greatest value (16ty-1). The fate and transport of ?6PAH were subsequently estimated by running the model an illustrative emission rate of 1molh-1. Organic film on impervious surfaces was the compartment that achieved the highest concentrations of PAHs, being up to 2.108ngm-3. However, as the film conveys chemicals to surface waters, the persistence in this compartment was <1day. Soils and sediments were the greatest sinks for PAHs, with a persistence of 100-1000days. The greatest loss of PAHs was due to advection from air, followed by photodegradation from air. These results provide a first approximation of the current emissions and fate of PAHs in Tarragona County. PMID- 27692473 TI - Effect of combined spinal-epidural analgesia in labor on frequency of emergency cesarean delivery among nulliparous Chinese women. AB - OBJECTIVE: To determine whether combined spinal-epidural analgesia (CSEA) during labor increases the frequency of emergency cesarean delivery among Chinese nulliparous women. METHODS: In a retrospective study, the medical records of nulliparous women with a singleton fetus in cephalic presentation who delivered at term at Tongling Maternity Hospital, China, between January 2012 and December 2014 were reviewed. Information about CSEA, mode of delivery, labor duration, oxytocin augmentation, and neonatal outcome was obtained. Logistic regression was used to examine independent associations between CSEA and emergency cesarean after controlling for confounding variables. RESULTS: Among 3456 women included, 1786 (51.7%) received CSEA and 1670 (48.3%) received no labor analgesia. Emergency cesarean was more frequent among CSEA users (219/1786 [12.3%]) than non users (119/1670 [7.1%]; P<0.001). Among the maternal-fetal variables included in multivariate regression, maternal age, maternal height, cervical dilatation at admission, birth weight, and CSEA use were significantly associated with emergency cesarean. After adjustment, women with CSEA maintained a slightly increased risk for cesarean (adjusted odds ratio 1.54, 95% confidence interval 1.20-2.00). CONCLUSION: Among Chinese nulliparous women, use of CSEA for labor pain was associated with an increased risk of emergency cesarean delivery; moreover, this effect was maintained after adjustment for other potential obstetric risk factors. PMID- 27692474 TI - Lateral-based Anterior Vaginal Wall Flap in the Treatment of Female Urethral Stricture: Efficacy and Safety. AB - BACKGROUND: Female urethral stricture is a rare condition. Different types of urethroplasty have been described. However, high quality studies are sparse. The most common technique used-the Blandy's technique-has resulted in our cases in a retrusive meatus and an inward urinary stream. OBJECTIVE: To show the efficacy and safety of an alternative vaginal wall flap urethroplasty. DESIGN, SETTING, AND PARTICIPANTS: A cross-sectional observational study was undertaken in a single University Hospital. Nine female patients previously diagnosed with urethral stricture at our institution underwent open surgery from 1993 to 2015. They were contacted and agreed to undergo a medical examination. SURGICAL PROCEDURE: A ventral lateral-based anterior vaginal wall flap urethroplasty inspired by the Orandi technique for male urethroplasty was performed. MEASUREMENTS: A chart review was performed. RESULTS AND LIMITATIONS: The mean age was 56 yr (41-78 yr). The mean follow-up was 80.7 mo (12-198). All patients had relief of symptoms. The meatus of all patients stayed in an orthotopic position without any impact on the direction of the urinary stream. The average caliber of the urethra increased from 10.8 Fr (6-18 Fr) to >=20 Fr. Peak flow improved from a mean of 6.8ml/s (3-11ml/s) to 21ml/s (14-35ml/s). No patient developed stricture recurrence or de novo stress urinary incontinence. There were no other immediate or delayed complications. All patients achieved a better score on the Patient Global Impression of Improvement questionnaire. CONCLUSIONS: Our study, with the same limitations that the few studies published in this field had, that is the few patients included, demonstrates that lateral anterior vaginal wall flap urethroplasty is an effective technique, offering durable results without apparent complications. PATIENT SUMMARY: We studied an alternative surgical technique for the treatment of female urethral stricture. We conclude that it is safe and effective with no apparent complications and good long-term results. PMID- 27692475 TI - Procedural training and assessment of competency utilizing simulation. AB - This review examines the current environment of neonatal procedural learning, describes an updated model of skills training, defines the role of simulation in assessing competency, and discusses potential future directions for simulation based competency assessment. In order to maximize impact, simulation-based procedural training programs should follow a standardized and evidence-based approach to designing and evaluating educational activities. Simulation can be used to facilitate the evaluation of competency, but must incorporate validated assessment tools to ensure quality and consistency. True competency evaluation cannot be accomplished with simulation alone: competency assessment must also include evaluations of procedural skill during actual clinical care. Future work in this area is needed to measure and track clinically meaningful patient outcomes resulting from simulation-based training, examine the use of simulation to assist physicians undergoing re-entry to practice, and to examine the use of procedural skills simulation as part of a maintenance of competency and life-long learning. PMID- 27692476 TI - Neonatal outreach simulation. AB - Numerous factors contribute to neonatal morbidity and mortality, and inexperienced providers managing crisis situations is one major cause. Simulation based medical education is an excellent modality to employ in community hospitals to help refine and refresh resuscitation skills of providers who infrequently encounter neonatal emergencies. Mounting evidence suggests that simulation-based education improves patient outcomes. Academic health centers have the potential to improve neonatal outcomes through collaborations with community hospital providers, sharing expertise in neonatal resuscitation and simulation. Community outreach programs using simulation have been successfully initiated in North America. Two examples of programs are described here, including the models for curricular development, required resources, limitations, and benefits. Considerations for initiating outreach simulation programs are discussed. In the future, research demonstrating improved neonatal outcomes using outreach simulation will be important for personnel conducting outreach programs. Neonatal outreach simulation is a promising educational endeavor that may ultimately prove important in decreasing neonatal morbidity and mortality.

AB - Poor communication between academic researchers and wildlife managers limits conservation progress and innovation. As a result, input from overlapping fields, such as animal behaviour, is underused in conservation management despite its demonstrated utility as a conservation tool and countless papers advocating its use. Communication and collaboration across these two disciplines are unlikely to improve without clearly identified management needs and demonstrable impacts of behavioural-based conservation management. To facilitate this process, a team of wildlife managers and animal behaviour researchers conducted a research prioritisation exercise, identifying 50 key questions that have great potential to resolve critical conservation and management problems. The resulting agenda highlights the diversity and extent of advances that both fields could achieve through collaboration.

AB - OBJECTIVE: To evaluate the usefulness of ultrasound-guided versus fluoroscopy guided injection in CT arthrography and MR arthrography. MATERIAL AND METHODS: We reviewed all CT arthrography and MR arthrography studies done at our center between October 1, 2014 and October 1, 2015. We analyzed 32 studies: 26 with fluoroscopic guidance and 6 with ultrasound guidance. We compared the two techniques on the following parameters: presence of sufficient contrast material in the joint, extravasation or injection of contrast material in the soft tissues (presence of contrast material in the psoas or other soft tissues), and intra articular gas bubbles. We used SPSS V. 20 to compare the techniques with Pearson's chi-square tests. RESULTS: Contrast material was observed in soft tissues in 56.3% of ultrasound-guided injections, making 6.3% of the procedures invalid for diagnostic purposes. Extravasation of contrast material was observed in 53.8% of fluoroscopy-guided procedures, making 3.8% invalid for diagnostic purposes. Intra-articular gas was observed in 21.9% of ultrasound-guided studies and in 38.5% of fluoroscopy-guided studies. None of the differences between techniques were statistically significant at p<0.05. CONCLUSIONS: Our study shows that ultrasound is as useful as fluoroscopy for injecting contrast material for CT arthroscopy and MR arthroscopy; ultrasound has the advantage of not using ionizing radiation. PMID- 27692485 TI - Determination of the concentrations of alternative antifouling agents on the Korean coast. AB - Since the ban on tributyltin (TBT) in 2008, dozens of alternative antifouling agents have been used instead. Unfortunately, these alternative antifouling agents contain diverse toxic components, which have contaminated the coasts. From 2006 to 2013, the concentration of chlorothalonil, dichlofluanid, and Irgarol 1051 were monitored continuously, and their mean concentrations increased due to the increase in maritime cargo and consequent increase in the incoming and outgoing ships in harbors. An analysis of the sampling points according to harbor type showed that the contamination was more severe in fishing and big harbors, where there are more incoming and outgoing ships. A correlation analysis indicated a high correlation between chlorothalonil and dichlofluanid. Unlike Irgarol 1051, which is only used as an antifouling agent, the other two substances are used as agricultural chemicals as well, which could explain the high correlation. This study suggests that these alternative antifouling agents should be tracked continuously. PMID- 27692486 TI - Excess seawater nutrients, enlarged algal symbiont densities and bleaching sensitive reef locations: 2. A regional-scale predictive model for the Great Barrier Reef, Australia. AB - A spatial risk assessment model is developed for the Great Barrier Reef (GBR, Australia) that helps identify reef locations at higher or lower risk of coral bleaching in summer heat-wave conditions. The model confirms the considerable benefit of discriminating nutrient-enriched areas that contain corals with enlarged (suboptimal) symbiont densities for the purpose of identifying bleaching sensitive reef locations. The benefit of the new system-level understanding is showcased in terms of: (i) improving early-warning forecasts of summer bleaching risk, (ii) explaining historical bleaching patterns, (iii) testing the bleaching resistant quality of the current marine protected area (MPA) network (iv) identifying routinely monitored coral health attributes, such as the tissue energy reserves and skeletal growth characteristics (viz. density and extension rates) that correlate with bleaching resistant reef locations, and (v) targeting region-specific water quality improvement strategies that may increase reef-scale coral health and bleaching resistance. PMID- 27692487 TI - The ITS-based phylogeny of fungi associated with tarballs. AB - Tarballs, the remnants of crude oil which change into semi-solid phase due to various weathering processes in the sea, are rich in hydrocarbons, including toxic and almost non-degradable hydrocarbons. Certain microorganisms such as fungi are known to utilize hydrocarbons present in tarballs as sole source of carbon for nutrition. Previous studies have reported 53 fungal taxa associated with tarballs. There is apparently no gene sequence-data available for the published taxa so as to verify the fungal identification using modern taxonomic tools. The objective of the present study is to isolate fungi from tarballs collected from Candolim beach in Goa, India and investigate their phylogenetic diversity based on 5.8S rRNA gene and the flanking internal transcribed spacer regions (ITS) sequence analysis. In the ITS-based NJ tree, eight tarball associated fungal isolates clustered with 3 clades of Dothideomycetes and 2 clades of Saccharomycetes. To the best of our knowledge, this is the first study that has employed ITS-based phylogeny to characterize the fungal diversity associated with tarballs. Further studies are warranted to investigate the role of the tarball-associated fungi in degradation of recalcitrant hydrocarbons present in tarballs and the role of tarballs as carriers of human pathogenic fungi. PMID- 27692488 TI - Large microplastic particles in sediments of tributaries of the River Thames, UK Abundance, sources and methods for effective quantification. AB - : Sewage effluent input and population were chosen as predictors of microplastic presence in sediments at four sites in the River Thames basin (UK). Large microplastic particles (1mm-4mm) were extracted using a stepwise approach to include visual extraction, flotation and identification using Raman spectroscopy. Microplastics were found at all four sites. One site had significantly higher numbers of microplastics than other sites, average 66 particles 100g-1, 91% of which were fragments. This site was downstream of a storm drain outfall receiving urban runoff; many of the fragments at this site were determined to be derived of thermoplastic road-surface marking paints. At the remaining three sites, fibres were the dominant particle type. The most common polymers identified included polypropylene, polyester and polyarylsulphone. This study describes two major new findings: presence of microplastic particles in a UK freshwater system and identification of road marking paints as a source of microplastics. CAPSULE: This study is the first to quantify microplastics of any size in river sediments in the UK and links their presence to terrestrial sources including sewage and road marking paints. PMID- 27692489 TI - History and the future: Looking back to look forward? AB - History is often dismissed as of little utility in the analysis of policy. This paper provides a justification for its use as evidence. It surveys the rise of the use of history, including public history and history and policy. It looks at two issues which draw on the author's own work: the relationship between regulation and culture for smoking and alcohol; and the response to electronic cigarettes in the light of smoking and public health history. It analyses what history can contribute. Responses are time dependent and change is an essential parameter in understanding policy. Historical research can challenge stereotypes, for example that prohibition was abandoned because it 'failed'. It also forms the bedrock of historical interpretation, which is mutable and often misunderstood outside the profession. History provides policy analysis rather than policy prescription and is a challenging approach, not just a convenient support for established positions. The paper concludes that history is far from moribund as a policy science. PMID- 27692492 TI - Older persons' expressions of emotional cues and concerns during home care visits. Application of the Verona coding definitions of emotional sequences (VR CoDES) in home care. AB - OBJECTIVE: This study aims to a) explore to what extent older persons express emotional cues and concerns during home care visits; b) describe what cues and concerns these older persons expressed, and c) explore who initiated these cues and concerns. METHODS: A descriptive and cross-sectional study was conducted. Data consisted of 188 audio recorded home care visits with older persons and registered nurses or nurse assistants, coded with the Verona coding definitions on emotional sequences (VR-CoDES). RESULTS: Emotional expressions of cues and concerns occurred in 95 (51%) of the 188 recorded home care visits. Most frequent were implicit expressions of cues (n=292) rather than explicit concerns (n=24). Utterances with hints to hidden concerns (63,9%, n=202) were most prevalent, followed by vague or unspecific expressions of emotional worries (15,8%, n=50). Most of these were elicited by the nursing staff (63%, n=200). CONCLUSION: Emotional needs expressed by the older persons receiving home care were mainly communicated implicitly. To be attentive to such vaguely expressed emotions may demand nursing staff to be sensitive and open. PRACTICE IMPLICATIONS: The VR CoDES can be applied on audio recorded home care visits to analyse verbal and emotional communication, and may allow comparative research.

AB - OBJECTIVE: To analyze the effects of a decision aid on improving patients' and family members' information giving and question asking during consultations for prostate cancer treatment decision-making. METHODS: This study is a secondary analysis of archived audio-recorded real-time consultation visits with participants from a randomized clinical trial. Participants were randomly assigned into three groups: TD-intervention targeted patient-only; TS intervention targeted patients and family members; and control-a handout on staying healthy during treatment. We conducted content analysis using a researcher-developed communication coding system. Using SAS 9.3, we conducted Chi square/Fisher's exact test to examine whether information giving and question asking among patients and family members varied by groups when discussing different content/topics. RESULTS: Compared with those in the TS and control groups, significantly higher percentages of participants in the TD group demonstrated information giving in discussing topics about diagnosis, treatment options, risks and benefits, and preferences; and engaged in question asking when discussing diagnosis, watchful waiting/active surveillance, risks and benefits, and preferences for treatment impacts. CONCLUSION: Information support and communication skills training for patients were effective in improving communication during treatment decision-making consultations. PRACTICE IMPLICATIONS: Providing information about prostate cancer and communication skills training empower patients and their family members. PMID- 27692493 TI - Testing whether barriers to a hypothetical screening test affect unrelated perceived benefits and vice versa: A randomised, experimental study. AB - OBJECTIVE: Determine whether (fictitious) health screening test benefits affect perceptions of (unrelated) barriers, and barriers affect perceptions of benefits. METHODS: UK adults were recruited via an online survey panel and randomised to receive a vignette describing a hypothetical screening test with either high or low benefits (higher vs. lower mortality reduction) and high or low barriers (severe vs. mild side-effects; a 2*2 factorial design). ANOVAs compared mean perceived benefits and barriers scores. Screening 'intentions' were compared using Pearson's chi2 test. RESULTS: Benefits were rated less favourably when barriers were high (mean: 27.4, standard deviation: 5.3) than when they were low (M: 28.5, SD: 4.8; p=0.010, partial eta2=0.031). Barriers were rated more negatively when benefits were low (M: 17.1, SD: 7.6) than when they were high (M: 15.7, SD: 7.3; p=0.023, partial eta2=0.024). Most intended to have the test in all conditions (73-81%); except for the low benefit-high barrier condition (37%; p<0.0005; N=218). CONCLUSIONS: Perceptions of test attributes may be influenced by unrelated characteristics. PRACTICE IMPLICATIONS: Reducing screening test barriers alone may have suboptimal effects on perceptions of barriers if benefits remain low; increasing screening benefits may not improve perceptions of benefits if barriers remain high. PMID- 27692494 TI - Personal trainers are confident in their ability to provide nutrition care: a cross-sectional investigation. AB - OBJECTIVE: To measure the self-perceived competence of Australian personal trainers in providing nutrition care. STUDY DESIGN: Cross-sectional online survey. METHODS: A validated survey was used to measure confidence in the ability to provide nutrition care among a snowball sample of 142 Australian-based personal trainers. The survey used 5-point Likert scale statements across four nutrition related constructs: knowledge; skills; communication and counselling; and attitudes. Scores for each construct were averaged and summed to provide a self-reported nutrition competence score as a percentage. Pearson Chi-squared analyses were used to identify associations between demographic variables and competence scores, and associations between construct scores. RESULTS: Personal trainers felt confident to provide nutrition care for all clients (mean score 76%; 'very confident'). Greater confidence in nutrition knowledge was seen in personal trainers with greater experience (chi2 = 6.946, P = 0.008) and education higher than a certificate IV (chi2 = 5.079, P = 0.024). Greater confidence in nutrition knowledge was also associated with greater confidence in nutrition skills (chi2 = 49.67, P <= 0.001) and more favourable attitudes towards providing nutrition care (chi2 = 4.73, P = 0.03). CONCLUSIONS: Personal trainers feel confident in their ability and show favourable attitudes towards providing nutrition care to clients. This workforce has the potential to support lifestyle modification for chronic disease prevention. PMID- 27692495 TI - Understanding brain development: a major step. PMID- 27692496 TI - Clinicopathologic factors associated with de novo metastatic breast cancer. AB - While breast cancers with distant metastasis at presentation (de novo metastasis) harbor significantly inferior clinical outcomes, there have been limited studies analyzing the clinicopathologic characteristics in this subset of patients. In this study, we analyzed 6126 breast cancers diagnosed between 1998 and 2013 to identify factors associated with de novo metastatic breast cancer. When compared to patients without metastasis at presentation, race, histologic grade, estrogen/progesterone receptor (ER/PR) and HER2 statuses were significantly associated with de novo metastasis in the entire cohort, whereas age, histologic grade, PR and HER2 status were the significant parameters in the subset of patients with locally advanced breast cancer (Stage IIB/III). The patients with de novo metastatic breast cancer had a significant older mean age and a lower proportion of HER2-positive tumors when compared to those with metastatic recurrence. Further, the HER2-rich subtype demonstrated a drastically higher incidence of de novo metastasis when compared to the luminal and triple-negative breast cancers in the entire cohort [odds ratio (OR)=5.68 and 2.27, respectively] and in the patients with locally advanced disease (OR=4.02 and 2.12, respectively), whereas no significant difference was seen between de novo metastatic cancers and those with metastatic recurrence. Moreover, the luminal and HER2-rich subtypes showed bone-seeking (OR=1.92) and liver-homing (OR=2.99) characteristics, respectively, for the sites of de novo metastasis, while the latter was not observed in those with metastatic recurrence. Our data suggest that an algorithm incorporating clinicopathologic factors, especially histologic grade and receptor profile, remains of significant benefit during decision making in newly diagnosed breast cancer in the pursuit of precision medicine.

AB - BACKGROUND: Polyhexamethylene biguanide (PHMB)-based antiseptic solutions can reduce bacterial loads in different clinical settings and are believed to lower risk of infections. OBJECTIVE: We sought to assess the efficacy of a PHMB-based solution in lowering bacterial loads of full-thickness skin grafting wounds and the risk of surgical site infections (SSIs). METHODS: In this double-blinded clinical trial, 40 patients planned for facial full-thickness skin grafting were randomized 1:1 to receive tie-over dressings soaked with either PHMB-based solution or sterile water. Quantitative and qualitative bacterial analysis was performed on all wounds before surgery, at the end of surgery, and 7 days postoperatively. In addition, all patients were screened for nasal colonization of Staphylococcus aureus. RESULTS: Analysis of wounds showed no statistically significant difference in bacterial reductions between the groups. The SSI rates were significantly higher in the intervention group (8/20) than in the control group (2/20) (P = .028). Higher postoperative bacterial loads were a common finding in SSIs (P = .011). This was more frequent when S aureus was present postoperatively (P = .034), intraoperatively (P = .03), and in patients with intranasal S aureus colonization (P = .007). LIMITATIONS: Assessment of SSIs is largely subjective. In addition, this was a single-center study and the total number of participants was 40. CONCLUSION: Soaking tie-over dressings with PHMB solution in full-thickness skin grafting had no effect on postoperative bacterial loads and increased the risk of SSI development. The presence of S aureus intranasally and in wounds preoperatively and postoperatively increased postoperative bacterial loads, which in turn resulted in significantly more SSIs.

AB - Species may be prevented from interspecific hybridization by a number of different reproductive barriers that operate precopulatory and postcopulatory. In situation, when natural precopulatory reproductive barriers are affected by anthropogenic factors, postcopulatory reproductive barriers may be important for maintaining gametic isolation and hence preventing interspecific hybridization. This is highly topical in sturgeon (order Acipenseriformes) which exhibits remarkable ease of interspecific hybridization. The objectives of the present study were to evaluate the fertilization success of Acipenser ruthenus and Acipenser baerii spermatozoa under the interspecific competitive conditions and assessed, whether their spermatozoa tend to differentially fertilize eggs of conspecifics. We set up several in vitro fertilization experiments: (i) pooled eggs of both species were fertilized by sperm of each species separately; (ii) eggs of each species were fertilized by pooled sperm; (iii) pooled eggs were fertilized by pooled sperm and (iv) purebred and hybrid control groups. Using parental assignment by molecular markers, we found that when these species competed in pooled sperm, 78.9% of progeny were sired by A. ruthenus and 21.1% by A. baerii, demonstrating higher fertilization success for the former, irrespective of conspecificity of fertilized eggs. When pooled eggs were inseminated by A. ruthenus or A. baerii sperm separately, progeny almost equally comprised hybrid and purebred individuals. Hence, neither A. ruthenus nor A. baerii eggs showed a tendency to biased fertilization by spermatozoa of conspecific males. These findings together show that there may not be postcopulatory mechanisms preventing hybridization between A. ruthenus and A. baerii.

AB - BACKGROUND: Itch is a prevalent symptom of psoriasis that impacts quality of life. OBJECTIVE: We sought to describe improvements in itch severity, skin pain, and bothersomeness of skin appearance caused by psoriasis among patients who received ixekizumab, etanercept, or placebo in three 12-week, phase III clinical trials (UNCOVER-1, -2, and -3). METHODS: The itch numeric rating scale evaluated psoriasis itch severity in all 3 trials. Skin pain was assessed by skin pain visual analog scale. Bothersomeness because of redness/discoloration, thickness, and scaling/flaking was assessed with the Psoriasis Skin Appearance Bothersomeness instrument. Psoriasis skin appearance bothersomeness and skin pain were assessed at baseline and week 12; itch numeric rating scale score was assessed at baseline and weeks 1, 2, 4, 8, and 12. RESULTS: Patients who received ixekizumab demonstrated statistically significant improvements (P < .001) in itch severity, reduction in skin pain, and degree of bothersomeness compared with those who received etanercept or placebo. Clinically meaningful improvements in itch severity were achieved as early as week 1. LIMITATIONS: Longer-term evaluations of psoriasis symptom improvement with ixekizumab treatment are needed. CONCLUSION: After treatment with ixekizumab, patients reported fast, significant, and clinically meaningful improvements in itch severity and other psoriasis-related symptoms such as skin pain and skin appearance bothersomeness.

PMID- 27692501 TI - Sexual chemoecology of mosquitoes (Diptera, Culicidae): Current knowledge and implications for vector control programs. AB - Mosquitoes (Diptera: Culicidae) act as vectors of medical and veterinary importance, due to their ability to transmit many pathogens and parasites. Renewed interest has been recently devoted to the potential of sterile insect technique (SIT) for mosquito suppression. However, the success of the SIT is mostly dependent on the ability of sterile males to compete for mates with the wild ones in the field. Nevertheless, little is known on the sexual chemical ecology of mosquitoes, with special reference to the role of chemical signals in males. We reviewed the current knowledge on mosquito sexual chemical ecology and other key cues affecting courtship and mating behavior. The information available on the aggregation and sex pheromones in mosquito males is rather limited. To the best of our knowledge, the components of the aggregation pheromone stimulating swarming mechanisms have been fully characterized only for Aedes aegypti, while evidence for aggregation pheromones in other mosquito species remains elusive. Further research on this issue is needed, as well as to dissect the relative importance of visual (with special reference to swarming landmarks), vibrational, olfactory and tactile cues perceived during swarming and mate. On the other hand, more knowledge is available for cuticular hydrocarbons, which modulate mating behavior in several species of economic importance. These compounds, coupled with volatile aggregation components, have potential interest for the development of monitoring and trapping systems. In addition, the analyses of cuticular hydrocarbons are essential for discrimination between closely related mosquito species and/or populations.

AB - Intraoperative rerupture (IOR) during clipping of cerebral aneurysms is a difficult complication of microneurosurgery. The aim of this study was to evaluate the incidence of IOR and analyze the strategies for controlling profound hemorrhage. A total of 165 patients with unruptured intracranial aneurysms and 46 patients with subarachnoid hemorrhage (SAH) treated surgically between April 2010 and March 2011, were reviewed. The data were collected with regard to age, sex, presence of symptoms, confounding factors and strategy for controlling intraoperative hemorrhage was analyzed in terms of location of aneurysms, timing of rupture and severity of IOR. 211 patients with 228 aneurysms were treated in this series. There were a total of six IORs which represented an IOR rate of 2.84% per patient and 2.63% per aneurysm. The highest ruptures rates occurred in patients with internal carotid artery aneurysms (25%). Surgeries in the group with ruptured aneurysms had a much higher rate of IOR compared with surgeries in the group with unruptured aneurysms. Of the six IOR aneurysms, one occurred during predissection, four during microdissection and one during clipping. One was major IOR, three were moderate and two were minor. Intraoperative rupture of an intracranial aneurysm can be potentially devastating in vascular neurosurgery. Aneurysm location, presence of SAH and surgical experience of the operating surgeon seem to be important factors affecting the incidence of IOR.

A longitudinal case report. AB - Nasal type extranodal natural killer/T-cell lymphoma (ENKTL) is a rare lymphoma in the USA and Europe but endemic in East Asia and in areas of South and Central America. Clinically natural killer cell lymphomas are divided into three categories; nasal, non-nasal and aggressive lymphoma/leukemia subtypes. ENKTL, nasal type occurs in the nose and can extend to the upper aero-digestive tract as reported in this longitudinal case study. This is a longitudinal report of progress of a 14-year-old boy with ENKTL originating in the nasal cavity with subsequent extension and recurrence in the contralateral nose, nasopharynx, larynx and trachea presenting with varying degrees of respiratory problems and eventually, respiratory distress. Caregiver refusal of stem cell transplantation prompted an alternative diagnostic and therapeutic approach. Clinical course with recurrences, extensions and remissions over 6years with tailored endoscopic surgical treatment and radiochemotherapy is documented to present a guide in the multidisciplinary management of this rare disease. PMID- 27692504 TI - Association of Healthy Home Environments and Use of Patient-Centered Medical Homes by Children of Low-Income Families. AB - INTRODUCTION: Medicaid agencies have been promoting the patient-centered medical home (PCMH) model. Most caregivers choose physician practices for their children, and we hypothesized that those following healthier childrearing practices are more likely to seek care in a PCMH. METHOD: We selected children with public insurance plans (n = 20,801) from the 2011-2012 National Survey of Children's Health. We used generalized ordinal logistic regression with state fixed effects to assess the association between home environments and children's use of PCMHs. RESULTS: Children living in the healthiest homes were 1.33 times (p = .001) more likely to receive care from the highest level of PCMH. In states with early PCMH implementation, the odds increased to 2.11 times (p = .001). DISCUSSION: Our results show a significant, sizeable relationship between healthier home environments and the use of PCMH by children from low-income families. They provide implications for assessing the effect of PCMH use on health outcomes and use patterns.

PMID- 27692506 TI - Development of the 24/7 Nurse Practitioner Model on the Inpatient Pediatric General Surgery Service at a Large Tertiary Care Children's Hospital and Associated Outcomes. AB - Nurse practitioners (NPs) have been providing high-quality and safe patient care for a few decades, and evidence showing the extent of their impact is emerging. This article describes the implementation of a 24/7 NP patient care model on an inpatient pediatric general surgery service in a tertiary free-standing Children's Hospital in the Northeastern United States. The literature shows that there is limited evidence regarding NP models of care and their effect on patient outcomes. In response to policy changes leading to reduction of resident work hours and a more acute and complex inpatient pediatric general surgery patient population, our existing NP model evolved into a 24/7 NP Model in June 2011. The results from two quality improvement projects showed positive registered nurse and attending surgeon staff satisfaction with the 24/7 NP Model of care and a decreased trend of unplanned intensive care unit patient transfers after the 24/7 NP Model implementation. These findings further support the evidence in the literature that NPs provide safe and quality patient care. PMID- 27692507 TI - Environmental Tobacco Smoke: Public Perception of Risks of Exposing Children to Second- and Third-Hand Tobacco Smoke. AB - INTRODUCTION: Extensive evidence exists regarding health risks posed by children's exposure to second-hand smoke, and there is increasing evidence concerning the risks of third-hand smoke. This evidence is most meaningful if the public is aware of these risks and can help curb childhood exposure. METHODS: Participants were selected at an academic medical center and asked to complete a survey. Responses were compared based on respondents' smoking status and the presence or absence of children in their homes. RESULTS: A total of 310 adults responded. Nonsmokers and respondents living with children were more likely to see smoking in the home as affecting all the queried health problems (p < .05). Knowledge of the risks of second-hand smoke exposure is limited, and very few respondents perceived risk from third-hand smoke exposure. DISCUSSION: The widespread lack of awareness of the risks associated with environmental tobacco smoke must be addressed to curb childhood exposure.

PMID- 27692509 TI - Design, synthesis, and evaluation of novel porcupine inhibitors featuring a fused 3-ring system based on the 'reversed' amide scaffold. AB - The Wnt signaling pathway is an essential signal transduction pathway which leads to the regulation of cellular processes such as proliferation, differentiation and migration. Aberrant Wnt signaling is known to have an association with multiple cancers. Porcupine is an enzyme that catalyses the addition of palmitoleate to a serine residue in Wnt proteins, a process which is required for the secretion of Wnt proteins. Here we report the synthesis and structure activity-relationship of the novel porcupine inhibitors based on a 'reversed' amide scaffold. The leading compound 53 was as potent as the clinical compound LGK974 in a cell based STF reporter gene assay. Compound 53 potently inhibited the secretion of Wnt3A, therefore was confirmed to be a porcupine inhibitor. Furthermore, compound 53 showed excellent chemical and plasma stabilities. However, the clearance of compound 53 in liver microsomal tests was moderate to high, and the solubility of compound 53 was suboptimal. Collective efforts toward further optimization of this novel tricyclic template to develop better porcupine inhibitors will be subsequently undertaken and reported in due course. PMID- 27692510 TI - Synthesis and Pin1 inhibitory activity of thiazole derivatives. AB - Pin1 (Protein interacting with NIMA1) is a peptidyl prolyl cis-trans isomerase (PPIase) which specifically catalyze the conformational conversion of the amide bond of pSer/Thr-Pro motifs in its substrate proteins and is a novel promising anticancer target. A series of new thiazole derivatives were designed and synthesized, and their inhibitory activities were measured against human Pin1 using a protease-coupled enzyme assay. Of all the tested compounds, a number of thiazole derivatives bearing an oxalic acid group at 4-position were found to be potent Pin1 inhibitors with IC50 values at low micromolar level. The detailed structure-activity relationships were analyzed and the binding features of compound 10b (IC50 5.38MUM) was predicted using CDOCKER program. The results of this research would provide informative guidance for further optimizing thiazole derivatives as potent Pin1 inhibitors. PMID- 27692511 TI - Life cycle assessment of carbon capture and utilization from ammonia process in Mexico. AB - Post-combustion CO2 capture (PCC) of flue gas from an ammonia plant (AP) and the environmental performance of the carbon capture utilization (CCU) technology for greenhouse gas (GHG) emissions to an enhanced oil recovery (EOR) system in Mexico was performed as case study. The process simulations (PS) and life cycle assessment (LCA) were used as supporting tools to quantify the CO2 capture and their environmental impacts, respectively. Two scenarios were considered: 1) the AP with its shift and CO2 removal unit and 2) Scenario 1 plus PCC of the flue gas from the AP primary reformer (AP-2CO2) and the global warming (GW) impact. Also, the GW of the whole of a CO2-EOR project, from these two streams of captured CO2, was evaluated. Results show that 372,426 tCO2/year can be PCC from the flue gas of the primary reformer and 480,000 tons/y of capacity from the AP. The energy requirement for solvent regeneration is estimated to be 2.8 MJ/kgCO2 or a GW impact of 0.22 kgCO2e/kgCO2 captured. GW performances are 297.6 kgCO2e emitted/barrel (bbl) for scenario one, and 106.5 kgCO2e emitted/bbl for the second. The net emissions, in scenario one, were 0.52 tCO2e/bbl and 0.33 tCO2e/bbl in scenario two. Based on PS, this study could be used to evaluate the potential of CO2 capture of 4080 t/d of 4 ammonia plants. The integration of PS LCA to a PCC study allows the applicability as methodological framework for the development of a cluster of projects in which of CO2 could be recycled back to fuel, chemical, petrochemical products or for enhanced oil recovery (EOR). With AP-2CO2, "CO2 emission free" ammonia production could be achieved. PMID- 27692512 TI - Fourier transform infra-red (FTIR) spectroscopy investigation, dose effect, kinetics and adsorption capacity of phosphate from aqueous solution onto laterite and sandstone. AB - Environmental pollution by phosphate in developing countries is growing with extensive and diffuse pollution. Solving these problem with intensive technologies is very expensive. Using natural sorbent such as laterite and sandstone could be a solution. The main objective of the study is to evaluate the P-removal efficiency of these materials under various solution properties. Laterite and sandstone used mainly contain very high levels of finely grained iron and aluminum oxy-hydroxides and diverse dioctahedral clays. Phosphate adsorption tests were carried out using crushed laterite and sandstone. Optimal doses and pH effects on phosphate adsorption were studied with a potassium hydrogeno-phosphate solution of 5 mg/L at 30 degrees C. The main results were that the optimal dosage is 15 and 20 mg/L respectively for laterite and sandstone. The phosphate adsorptions efficiency of laterite and sandstone are pH dependent, they increase when the pH grows up to the Point of Zero Charge (PZC) and slowly decrease beyond. The adsorption capacities of the materials also increase proportionally with the initial phosphate concentration. The pseudo second-order successfully described the kinetics of the phosphate adsorption on the two adsorbents. With this model, the adsorption capacity values are obtained, which give an idea of the maximum phosphate uptake that the laterite and sandstone could achieve. The changes on the FTIR spectra of raw materials and phosphate adsorbed material confirm the mechanism of chemisorptions. Considering the above, laterite and sandstone could be used as efficient and cheap adsorbent for the removal of phosphate in aqueous solution. PMID- 27692513 TI - Cesium and strontium loads into a combined sewer system from rainwater runoff. AB - In this study, combined sewage samples were taken with time in several rain events and sanitary sewage samples were taken with time in dry weather to calculate Cs and Sr loads to sewers from rainwater runoff. Cs and Sr in rainwater were present as particulate forms at first flush and the particulate Cs and Sr were mainly bound with inorganic suspended solids such as clay minerals in combined sewage samples. In addition, multiple linear regression analysis showed Cs and Sr loads from rainwater runoff could be estimated by the total amount of rainfall and antecedent dry weather days. The variation of the Sr load from rainwater to sewers was more sensitive to total amount of rainfall and antecedent dry weather days than that of the Cs load. PMID- 27692514 TI - From municipal/industrial wastewater sludge and FOG to fertilizer: A proposal for economic sustainable sludge management. AB - After a ban on the depositing of untreated sludge in landfills, the sludge from municipal and industrial water-treatment plants can be regarded as a problem. Waste products of the water treatment process can be a problem or an opportunity a source for obtaining raw materials. In the European Union, raw sludge and fats, oil and grease (FOG) from municipal and industrial wastewater treatment plants (WWTP) cannot be deposited in any natural or controlled environment. For this reason, it must be processed (stabilized, dried) to be used later as a fertilizer, building material, or alternative fuel source suitable for co incineration in high temperature furnaces (power plants or concrete plants). The processes of drying sludge, where heat and electricity are used, are energy consuming and economically unattractive. Beside energy efficiency, the main problem of sludge drying is in its variability of quality as a raw material. In addition to this, sludge can be contaminated by a number of organic and inorganic pollutants and organisms. Due to the presence or absence of pollutants, different end products can be economically interesting. For example, if the dried sludge contains coliform bacteria, viruses, helminths eggs or smaller quantities of heavy metals, it cannot be used as a fertilizer but can still be used as a fuel. The objectives of the current article is to present a batch-processing pilot device of sludge or digestate that allows the following: (1) low pressure and low temperature energy effective drying of from 10 to 40% remaining water content, (2) disinfection of pathogen (micro)organisms, (3) heavy metal reduction, (4) production of products of predetermined quality (e.g. containing different quantities of water; it can be used as a fertilizer, or if the percentage of water in the dry sludge is decreased to 10%, then the dried sludge can be used as a fuel with a calorific value similar to coal). An important feature is also the utilization of low-pressure technology to prevent odorous gasses from spreading into the environment. There are presented two new technologies: a) Sewage sludge or digestate drying in the vacuum chamber consumes approx. 1 kWh/dm3 of evaporated water and, therefore, reaches a price of 180-240 Euros/t Dry Matter (DM), and b) Heavy metals' reduction using adsorbing reaction with magnetite nanostructures can decrease the level of heavy metals in the sewage sludge or digestate up to 20% in one cycle, which can be repeated several times on the same sludge. The aim of the paper is to present a newly developed technology which can provide economic and safe use of moderate heavy metals polluted sewage sludge on agricultural lands as organic fertilizer and, therefore, returning the nutrients (nitrogen, phosphorous, potassium) back to the human food chain, instead of being incinerated or landfilled. The proposed drying technology is economically sustainable due to the low vacuum and temperature (35 degrees C-40 degrees C), that increases the efficiency of the heat pump (coefficient of performance 5-7,2) of the energy produced by the anaerobic digestion. Hence, the main emphasis is given to the development of: an efficient method for heavy metals' reduction in the sludge treatment chain by using chitosan covered magnetite nanoparticles, an efficient drying method in a vacuum with low temperature energy which can be exploited from sludge digestion to reduce organic matter, and an energy sustainable concept of sludge treatment, with the addition of fats, oil and grease (FOG) to produce enough biogas for sludge drying to produce fertilizer. PMID- 27692515 TI - Mapping discourses using Q methodology in Matang Mangrove Forest, Malaysia. AB - The sustainable management of natural resources requires the consideration of multiple stakeholders' perspectives and knowledge claims, in order to inform complex and possibly contentious decision-making dilemmas. Hence, a better understanding of why people in particular contexts do manage natural resources in a particular way is needed. Focusing on mangroves, highly productive tropical intertidal forests, this study's first aim is to map the diversity of subjective viewpoints among a range of stakeholders on the management of Matang Mangrove Forest in peninsular Malaysia. Secondly, this study aims to feed the reflection on the possible consequences of the diversity of perspectives for the future management of mangroves in Malaysia and beyond. The use of the semi-quantitative Q methodology allowed us to identify three main discourses on mangrove management: i. the optimization discourse, stressing the need to improve the current overall satisfactory management regime; ii. the 'change for the better' discourse, which focuses on increasingly participatory management and on ecotourism; and iii. the conservative 'business as usual' discourse. The existence of common points of connection between the discourses and their respective supporters provides opportunities for modifications of mangrove management regimes. Acknowledging this diversity of viewpoints, reflecting how different stakeholders see and talk about mangrove management, highlights the need to develop pro-active and resilient natural resource management approaches. PMID- 27692516 TI - Geotechnology and landscape ecology applied to the selection of potential forest fragments for seed harvesting. AB - The Atlantic Forest biome is recognized for its biodiversity and is one of the most threatened biomes on the planet, with forest fragmentation increasing due to uncontrolled land use, land occupation, and population growth. The most serious aspect of the forest fragmentation process is the edge effect and the loss of biodiversity. In this context, the aim of this study was to evaluate the dynamics of forest fragmentation and select potential forest fragments with a higher degree of conservation for seed harvesting in the Itapemirim river basin, Espirito Santo State, Brazil. Image classification techniques, forest landscape ecology, and multi-criteria analysis were used to evaluate the evolution of forest fragmentation to develop the landscape metric indexes, and to select potential forest fragments for seed harvesting for the years 1985 and 2013. According to the results, there was a reduction of 2.55% of the occupancy of the fragments in the basin between the years 1985 and 2013. For the years 1985 and 2013, forest fragment units 2 and 3 were spatialized with a high potential for seed harvesting, representing 6.99% and 16.01% of the total fragments, respectively. The methodology used in this study has the potential to be used to support decisions for the selection of potential fragments for seed harvesting because selecting fragments in different environments by their spatial attributes provides a greater degree of conservation, contributing to the protection and conscious management of the forests. The proposed methodology can be adapted to other areas and different biomes of the world. PMID- 27692517 TI - Simultaneous detoxification and bioethanol fermentation of furans-rich synthetic hydrolysate by digestate-based pyrochar. AB - Pyrolysis is a sustainable pathway to transform renewable biomasses into both biofuels and advanced carbonaceous materials (i.e. pyrochar) which can be used as adsorbent of furan compounds. In particular, the aim of this study was to: i) evaluate the effect of vibro-ball milling on physical characteristics of pyrochar and its consequent performance on solely detoxification of a synthetic medium, containing furans and soluble sugars; ii) study the simultaneous detoxification and bioethanol fermentation, by adding activated pyrochar into fermentation medium. Results demonstrated that, compared to untreated pyrochar, the use of milled pyrochar increased by 52% furfural removal from the synthetic medium. Furfural removal rate was also increased (adsorption kinetic constant increased from 0.015 min-1 up to 0.215 min-1), at a pyrochar loading of 40 g L-1. Although, the simultaneous addition of pyrochar into the fermentation medium did not improve the bioethanol yield of the synthetic medium, it has significantly increased the bioethanol production rate. PMID- 27692518 TI - Treatment planning strategy for whole-brain radiotherapy with hippocampal sparing and simultaneous integrated boost for multiple brain metastases using intensity modulated arc therapy. AB - PURPOSE: To retrospectively evaluate the accuracy, plan quality and efficiency of intensity-modulated arc therapy (IMAT) for hippocampal sparing whole-brain radiotherapy (HS-WBRT) with simultaneous integrated boost (SIB) in patients with multiple brain metastases (m-BM). MATERIALS AND METHODS: A total of 5 patients with m-BM were retrospectively replanned for HS-WBRT with SIB using IMAT treatment planning. The hippocampus was contoured on diagnostic T1-weighted magnetic resonance imaging (MRI) which had been fused with the planning CT image set. The hippocampal avoidance zone (HAZ) was generated using a 5-mm uniform margin around the paired hippocampi. The m-BM planning target volumes (PTVs) were contoured on T1/T2-weighted MRI registered with the 3D planning computed tomography (CT). The whole-brain planning target volume (WB-PTV) was defined as the whole-brain tissue volume minus HAZ and m-BM PTVs. Highly conformal IMAT plans were generated in the Eclipse treatment planning system for Novalis-TX linear accelerator consisting of high-definition multileaf collimators (HD-MLCs: 2.5-mm leaf width at isocenter) and 6-MV beam. Prescription dose was 30Gy for WB PTV and 45Gy for each m-BM in 10 fractions. Three full coplanar arcs with orbit avoidance sectors were used. Treatment plans were evaluated using homogeneity (HI) and conformity indices (CI) for target coverage and dose to organs at risk (OAR). Dose delivery efficiency and accuracy of each IMAT plan was assessed via quality assurance (QA) with a MapCHECK device. Actual beam-on time was recorded and a gamma index was used to compare dose agreement between the planned and measured doses. RESULTS: All 5 HS-WBRT with SIB plans met WB-PTV D2%, D98%, and V30Gy NRG-CC001 requirements. The plans demonstrated highly conformal and homogenous coverage of the WB-PTV with mean HI and CI values of 0.33 +/- 0.04 (range: 0.27 to 0.36), and 0.96 +/- 0.01 (range: 0.95 to 0.97), respectively. All 5 hippocampal sparing patients met protocol guidelines with maximum dose and dose to 100% of hippocampus (D100%) less than 16 and 9Gy, respectively. The dose to the optic apparatus was kept below protocol guidelines for all 5 patients. Highly conformal and homogenous radiosurgical dose distributions were achieved for all 5 patients with a total of 33 brain metastases. The m-BM PTVs had a mean HI = 0.09 +/- 0.02 (range: 0.07 to 0.19) and a mean CI = 1.02 +/- 0.06 (range: 0.93 to 1.2). The total number of monitor units (MU) was, on average, 1677 +/- 166. The average beam-on time was 4.1 +/- 0.4 minute . The IMAT plans demonstrated accurate dose delivery of 95.2 +/- 0.6%, on average, for clinical gamma passing rate with 2%/2-mm criteria and 98.5 +/- 0.9%, on average, with 3%/3-mm criteria. CONCLUSIONS: All hippocampal sparing plans were considered clinically acceptable per NRG-CC001 dosimetric compliance criteria. IMAT planning provided highly conformal and homogenous dose distributions for the WB-PTV and m-BM PTVs with lower doses to OAR such as the hippocampus. These results suggest that HS-WBRT with SIB is a clinically feasible, fast, and effective treatment option for patients with a relatively large numbers of m-BM lesions. PMID- 27692519 TI - [Inter-observer variability of decision concerning the route of delivery in case of one previous cesarean section and abnormal pelvic measures]. AB - OBJECTIVES: To study inter-observer variability of decision concerning the route of delivery using pelvimetry in case of one previous cesarean section and abnormal pelvic measures. MATERIALS AND METHOD: Observational study conducted in 2014 in 4 university maternity units among 36 obstetricians. Two groups of obstetricians - as they practiced in a center where pelvimetry was routinely performed (n=12) or not (n=24) - had to choose a route of delivery for 10 clinical cases of women with a single uterine scar and a tight pelvis. The "routine pelvimetry" group had pelvimetry results. The group "no pelvimetry" became aware of pelvimetry results as a second step and had to indicate whether this information changed or not their management. The measurement of the inter observer variability was estimated by estimating the proportion of agreement according to Grant method. RESULTS: The proportion of agreements of an attempted vaginal delivery between obstetricians in the group "routine pelvimetry" was 64.7% (95% CI [61-68.5]) and 97.3% (95% CI [96.4 to 98.3]) in the group "no pelvimetry", prior knowledge of pelvimetry results. An attempted vaginal delivery was decided in 77.5% versus 98.7% (P<0.001). After knowledge of pelvimetry results in the group "no pelvimetry" had, the number of attempted vaginal deliver was not different (77.5% vs. 78%, P=0.920). CONCLUSION: In women with one previous cesarean section, in case of tight pelvis discovered after pelvimetry, inter-observer variability of decision concerning the route of delivery is increased. Centers that choose to continue using the routine pelvimetry should develop procedures to limit this variability. PMID- 27692520 TI - [Placental site trophoblastic tumor: When do we suspect it and which treatment shall we decide?] AB - Tumors of trophoblast implantation site TTSI are rare gestational tumors. This case highlights the diagnostic difficulties and treatment of tumors of trophoblastic implantation site early. Patient of 28 years with no medical history, G1P1 who gave birth 11 months ago presented bleeding with an HCG level of 73IU that led to the diagnosis of early miscarriage. Treatment of miscarriage by hysteroscopy and curettage is complicated leading to the realization of an abdominopelvic CT and pelvic ultrasound that show an atypical uterine vascularity and an intracavitary heterogeneous mass. The pelvic MRI performed evokes a TTSI stage I. A hysterectomy with bilateral salpingectomy and ovarian conservation is achieved. Despite the standard treatment with surgery the HCG levels do not normalize before seven months after surgery. This indicates an adjuvant chemotherapy, the patient refuses. The presented case illustrates the diagnostic difficulties of the disease. He noted the importance of the second reading network proposed by the specialized center in Lyon. It also raises the question of adjuvant chemotherapy in some cases of early stage TTSI. The challenge is to define cases requiring adjuvant therapy. Predictors of chemotherapy in early stages could be tumor size, degree of infiltration of the myometrium and mutation p53. Amenorrhea, bleeding associated with uterine atypical vascularization, and atypical development of HCG<1000IU and/or unusual complications of treatment of miscarriage should evoke a tumor site trophoblastic implantation. Hysterectomy is the first treatment in early stages. Tumor size, degree of infiltration of the myometrium and mutation p53 are predictors to assess in multicentre studies to define the indications of postoperative chemotherapy.

MATERIALS AND METHODS: It is about an exploratory study carried out in 61 unfertile SOPK patients, having profited all from a cycle of FIV/ICSI (intracytoplasmic sperm injection). We have divided our population in two groups according to their hormonal androgenic statute: groups with hyperandrogenism and without hyperandrogenism. We proceeded to note the anthropometric and hormonal parameters as well as results of FIV for each of the two groups. RESULTS: SOPK patients with hyperandrogenism are more obese than their counterparts. Also, they have more oocytes collected after ovarian induction. In addition, we did not reveal any significant differences between our two study groups concerning parameters defining FIV response. CONCLUSION: Our findings suggest that hyperandrogenism statute in SOPK infertile women does not seem to compromise the results of FIV. On the contrary, it would make it possible to optimize the chances to puncture more significant number of oocytes.

PMID- 27692522 TI - Structural, antigenic and immunogenic features of respiratory syncytial virus glycoproteins relevant for vaccine development. AB - Extraordinary progress in the structure and immunobiology of the human respiratory syncytial virus glycoproteins has been accomplished during the last few years. Determination of the fusion (F) glycoprotein structure folded in either the prefusion or the postfusion conformation was an inspiring breakthrough not only to understand the structural changes associated with the membrane fusion process but additionally to appreciate the antigenic intricacies of the F protein. Furthermore, these developments have opened new avenues for structure based designs of promising hRSV vaccine candidates. Finally, recent advances in our knowledge of the attachment (G) glycoprotein and its interaction with cell surface receptors have revitalized interest in this molecule as a vaccine, as well as its role in hRSV immunobiology. PMID- 27692523 TI - Development and clinical applications of novel antibodies for prevention and treatment of respiratory syncytial virus infection. AB - Respiratory syncytial virus (RSV) remains a significant cause of morbidity and mortality in infants and young children, immunocompromised patients and the elderly. Despite the high disease burden, an effective and safe vaccine is lacking, although several candidates are currently in development. Current treatment for RSV infection remains largely supportive and RSV-specific options for prophylaxis are limited to palivizumab. In the past few years, novel therapeutic options including nanobodies, polyclonal and monoclonal antibodies have emerged and there are several products in preclinical and Phase-I, -II or III clinical trials. The major target for antiviral drug development is the surface fusion (F) glycoprotein, which is crucial for the infectivity and pathogenesis of the virus. Solving the structures of the two conformations of the RSV F protein, the prefusion and postfusion forms, has revolutionized RSV research. It is now known that prefusion F is highly superior in inducing neutralizing antibodies. In this section we will review the stages of development and availability of different antibodies directed against RSV for the prevention and also for treatment of acute RSV infections. Some of these newer anti-RSV agents have shown enhanced potency, are being explored through alternative routes of administration, have improved pharmacokinetic profiles with an extended half life, and may reduce design and manufacturing costs. Management strategies will require targeting not only high-risk populations (including adults or immunocompromised patients), but also previously healthy children who, in fact, represent the majority of children hospitalized with RSV infection. Following treated patients longitudinally is essential for determining the impact of these strategies on the acute disease as well as their possible long-term benefits on lung morbidity. PMID- 27692525 TI - Adolescent confidence in immunisation: Assessing and comparing attitudes of adolescents and adults. AB - INTRODUCTION: There is limited knowledge of adolescent views and attitudes towards immunisation. Our study investigated adolescent attitudes to immunisation and compared differences in vaccination attitudes between adolescents and adults. METHODS: This study was a cross-sectional, national online survey. Recruitment was stratified by state and gender to ensure findings were nationally representative. Regression analyses were performed to assess and compare adolescent and adult views on vaccine benefits, community protection, risks, side effects, sources of information, and decision-making preference. RESULTS: In 2013, 502 adolescents and 2003 adults completed the online survey. Lower levels of vaccine confidence were observed in adolescents with adolescents less likely to believe vaccines are beneficial and/or safe compared to adults (p=0.043). Compared to females, males were less confident of vaccine benefits (p<0.05) but less concern about vaccine side effects (p<0.05). Adolescents were more concerned about vaccine side effects than adults for pain (p<0.001), redness or swelling (p<0.001), and fever (p=0.006). Adolescents were less likely than adults to consider health professionals (p<0.001) and the media (e.g. internet) (p=0.010) as important sources of information, and were more likely to seek information from social networks (p<0.001) including families and schools. Although 62.0% of adolescents agreed that parents should make the decision about vaccination for them, adolescents were more likely to prefer a joint decision with parents (p<0.001) or by themselves (p=0.007) compared with adults. CONCLUSION: Adolescents have a lesser understanding of vaccine safety and benefits than adults and have higher concerns about potential vaccine reactions. Improving adolescent awareness and knowledge of the benefits and risks of vaccination through school-based educational programs may improve confidence in and uptake of vaccines for adolescents and increase vaccine confidence in the next generation of parents. PMID- 27692526 TI - Intravitreal Sirolimus for Noninfectious Uveitis: A Phase III Sirolimus Study Assessing Double-masKed Uveitis TReAtment (SAKURA). AB - PURPOSE: To evaluate the efficacy and safety of intravitreal sirolimus in the treatment of noninfectious uveitis (NIU) of the posterior segment (i.e., posterior, intermediate, or panuveitis). DESIGN: Phase III, randomized, double masked, active-controlled, 6-month study with intravitreal sirolimus. PARTICIPANTS: Adults with active NIU of the posterior segment (intermediate, posterior, or panuveitis), defined as a vitreous haze (VH) score >1+. Subjects discontinued NIU medications before baseline, except for systemic corticosteroids, which were allowed only for those already receiving them at baseline and were rapidly tapered after baseline per protocol. METHODS: Intravitreal sirolimus assigned 1:1:1 at doses of 44 (active control), 440, or 880 MUg, administered on Days 1, 60, and 120. MAIN OUTCOME MEASURES: The primary efficacy outcome was the percentage of subjects with VH 0 response at Month 5 (study eye) without use of rescue therapy. Secondary outcomes at Month 5 were VH 0 or 0.5+ response rate, corticosteroid tapering success rate (i.e., tapering to a prednisone-equivalent dosage of <=5 mg/day), and changes in best-corrected visual acuity (BCVA). Adverse events during the double-masked treatment period are presented. RESULTS: A total of 347 subjects were randomized. Higher proportions of subjects in the intravitreal sirolimus 440 MUg (22.8%; P = 0.025) and 880 MUg (16.4%; P = 0.182) groups met the primary end point than in the 44 MUg group (10.3%). Likewise, higher proportions of subjects in the 440 MUg (52.6%; P = 0.008) and 880 MUg (43.1%; P = 0.228) groups achieved a VH score of 0 or 0.5+ than in the 44 MUg group (35.0%). Mean BCVA was maintained throughout the study in each dose group, and the majority of subjects receiving corticosteroids at baseline successfully tapered off corticosteroids (44 MUg [63.6%], 440 MUg [76.9%], and 880 MUg [66.7%]). Adverse events in the treatment and active control groups were similar in incidence, and all doses were well tolerated. CONCLUSIONS: Intravitreal sirolimus 440 MUg demonstrated a significant improvement in ocular inflammation with preservation of BCVA in subjects with active NIU of the posterior segment. PMID- 27692527 TI - Adalimumab for Treatment of Noninfectious Uveitis: Immunogenicity and Clinical Relevance of Measuring Serum Drug Levels and Antidrug Antibodies. AB - PURPOSE: To evaluate the rate of immunogenicity induced by adalimumab and its relationship with drug serum levels and clinical responses in patients with noninfectious uveitis. DESIGN: Prospective observational study. PARTICIPANTS: Consecutive patients from 1 referral center who initiated treatment with adalimumab for active noninfectious uveitis resistant to conventional therapy. METHODS: All patients received 40 mg adalimumab every other week. Patients were evaluated clinically and immunologically before and after 4, 8, and 24 weeks of treatment. MAIN OUTCOME MEASURES: Clinical evaluation included assessment of changes in visual acuity, degree of inflammation in the anterior chamber and vitreous cavity, central macular thickness, and retinal angiographic leakage. Immunologic evaluation included assessment of serum trough adalimumab and antibodies against adalimumab (AAA) levels and class II HLA typing. RESULTS: Twenty-five patients were enrolled. Overall, 18 of 25 patients (72%) showed a favorable clinical response to adalimumab therapy. Eleven patients (44%) achieved a complete response and 7 (28%) achieved a partial response. However, 7 of 25 patients (28%) were considered nonresponders. Median trough adalimumab serum levels were higher in responders than in nonresponders (P < 0.001). We observed AAA positivity (AAA+) at least 1 time point in 8 of 25 patients (32%), including 4 with transitory AAA and 4 with permanent AAA. In all patients with permanent AAA+, trough adalimumab levels became undetectable (P < 0.001). However, in patients who demonstrated transitory AAA+, no correlation was observed between AAA titers and adalimumab trough levels (P = 0.2).Concomitant immunosuppression did not show any protective effect on adalimumab immunogenicity in our cohort. An association between the presence of AAA+ and a worse uveitis outcome was observed only in patients with permanent AAA+, which correlated with undetectable adalimumab trough levels (P = 0.014). CONCLUSIONS: Treatment of noninfectious uveitis with adalimumab is associated with high rates of favorable clinical response. Overall, adalimumab trough levels were higher in responder patients. Development of permanent AAA was associated with undetectable trough adalimumab levels and worse uveitis outcome. Immunogenicity was more common in patients in whom uveitis was associated with a systemic disease and was not influenced by concomitant immunosuppressors. PMID- 27692529 TI - A principal component analysis of the relationship between the external body shape and internal skeleton for the upper body. AB - Recent progress in 3D scanning technologies allows easy access to 3D human body envelope. To create personalized human models with an articulated linkage for realistic re-posturing and motion analyses, an accurate estimation of internal skeleton points, including joint centers, from the external envelope is required. For this research project, 3D reconstructions of both internal skeleton and external envelope from low dose biplanar X-rays of 40 male adults were obtained. Using principal component analysis technique (PCA), a low-dimensional dataset was used to predict internal points of the upper body from the trunk envelope. A least squares method was used to find PC scores that fit the PCA-based model to the envelope of a new subject. To validate the proposed approach, estimated internal points were evaluated using a leave-one-out (LOO) procedure, i.e. successively considering each individual from our dataset as an extra-subject. In addition, different methods were proposed to reduce the variability in data and improve the performance of the PCA-based prediction. The best method was considered as the one providing the smallest errors between estimated and reference internal points with an average error of 8.3mm anterior-posteriorly, 6.7mm laterally and 6.5mm vertically. As the proposed approach relies on few or no bony landmarks, it could be easily applicable and generalizable to surface scans from any devices. Combined with automatic body scanning techniques, this study could potentially constitute a new step towards automatic generation of external/internal subject-specific manikins. PMID- 27692528 TI - Pediatric Idiopathic Intracranial Hypertension: Age, Gender, and Anthropometric Features at Diagnosis in a Large, Retrospective, Multisite Cohort. AB - PURPOSE: To examine anthropometric and maturational characteristics at diagnosis in pediatric idiopathic intracranial hypertension (IIH). DESIGN: Retrospective, international, multisite study. PARTICIPANTS: Pediatric patients (2-18 years of age at diagnosis) with IIH. MAIN OUTCOME MEASURES: Body mass index (BMI), height, and weight Z-scores; sexual maturation. METHODS: Cases of IIH were identified retrospectively based on diagnostic code, pediatric neuro-ophthalmologist databases, or both and updated diagnostic criteria (2013) were applied to confirm definite IIH. Anthropometric measurements were converted into age- and gender specific height, weight, and BMI Z-scores CDC 2000 growth charts. When available, sexual maturation was noted. RESULTS: Two hundred thirty-three cases of definite IIH were identified across 8 sites. In boys, a moderate association between age and BMI Z-scores was noted (Pearson's correlation coefficient, 0.50; 95% confidence interval [CI], 0.30-0.66; P < 0.001; n = 72), and in girls, a weak association was noted (Pearson's correlation coefficient, 0.34; 95% CI, 0.20 0.47; P < 0.001; n = 161). The average patient was more likely to be overweight at diagnosis at age 6.7 years in girls and 8.7 years in boys, and obese at diagnosis at age 12.5 years in girls and 12.4 years in boys. Compared with age- and gender-matched reference values, early adolescent patients were taller for age (P = 0.002 in girls and P = 0.02 in boys). Data on Tanner staging, menarchal status, or both were available in 25% of cases (n = 57/233). Prepubertal participants (n = 12) had lower average BMI Z-scores (0.95+/-1.98) compared with pubertal participants (n = 45; 1.92+/-0.60), but this result did not reach statistical significance (P = 0.09). CONCLUSIONS: With updated diagnostic criteria and pediatric-specific assessments, the present study identifies 3 subgroups of pediatric IIH: a young group that is not overweight, an early adolescent group that is either overweight or obese, and a late adolescent group that is mostly obese. Data also suggest that the early adolescent group with IIH may be taller than age- and gender-matched reference values. Understanding these features of pediatric IIH may help to illuminate the complex pathogenesis of this condition. PMID- 27692530 TI - Total Skin Electron Beam Therapy in the Treatment of Mycosis Fungoides: A Review of Conventional and Low-Dose Regimens. AB - Mycosis fungoides (MF) is the most prevalent subtype of cutaneous T-cell lymphoma, which is characterized by the proliferation of CD4+ T cells. While often an indolent disease, most patients eventually develop progression from isolated patches to tumors and finally nodal or visceral involvement. Treatment choice is largely based on disease burden, though prognostic factors such as disease stage, patient age, and extracutaneous involvement must be taken into consideration. Radiotherapy represents one of the most effective therapeutic modalities in the treatment of MF. Lymphocytes are exquisitely radiosensitive, and excellent responses are observed even with low doses of radiation. Total skin electron beam therapy (TSEBT) is a special technique that allows for the homogenous irradiation of the entire skin. There are well-documented radiation dose-response relationships for achieving a complete response. As such, TSEBT doses >= 30 Gy comprise the current standard of care. Although highly effective, most patients experience recurrent disease even after conventional-dose (>= 30 Gy) TSEBT. In addition, toxicity is cumulatively dose dependent, and there is reluctance to administer multiple courses of conventional-dose TSEBT. Consequently, there has been renewed interest in determining the utility of TSEBT at lower total (<= 30 Gy) doses. Advantages of low-total-dose (with standard dose per fraction) TSEBT include a shortened treatment course, the potential to minimize the risk of adverse events, and the opportunity to allow for retreatment in cases of disease recurrence. This comprehensive review compares the impact of different TSEBT dosing schemes on clinical outcomes of MF. PMID- 27692531 TI - Identification and quantification of nuisance odors at a trash transfer station. AB - The objective of this study was to evaluate the effectiveness of a modified Odor Profile Method (OPM) at a trash transfer station (TTS). An updated Landfill Odor Wheel was used to define odor character and distinguish among odor sources. The Flavor Profile Analysis (FPA) intensity scale was used to rank the relative intensity of the various odor characters defined by the odor wheel and to understand how each odor profile changed off site. Finally, the odor wheel was used to select the appropriate chemical analysis to identify the odorants causing the odors identified by the human panelists. The OPM was demonstrated as an effective tool for characterizing and distinguishing odor sources at a TTS. Municipal solid waste (MSW) odors were characterized as rancid, sulfur, and fragrant; rancid odors were dominant in the odor profile on-site, while sulfur odors dominated off-site. Targeted chemical analysis was used to identify odorants potentially responsible for odors at the site. Methyl mercaptan (rotten vegetable) and hydrogen sulfide (rotten egg) were identified as the odorants most likely to be responsible for the sulfur odors at the site. Acetaldehyde (sweet, fruity), acetic acid (vinegar), and butyric acid (rancid) were identified as the odorants mostly likely to be causing the rancid and sour odors. Terpenes/pine odors were observed near the greenwaste pile. Results confirm that the OPM, together with properly selected chemical analyses, can be a useful tool for identifying and quantifying the sources of odors. PMID- 27692532 TI - Retrievable Inferior Vena Cava Filters in Trauma Patients: Prevalence and Management of Thrombus Within the Filter. AB - OBJECTIVE: The incidence of thrombus was investigated within retrievable filters placed in trauma patients with confirmed DVT at the time of retrieval and the optimal treatment for this clinical scenario was assessed. A technique called "filter retrieval with manual negative pressure aspiration thrombectomy" for management of filter thrombus was introduced and assessed. METHODS: The retrievable filters referred for retrieval between January 2008 and December 2015 were retrospectively reviewed to determine the incidence of filter thrombus on a pre-retrieval cavogram. The clinical outcomes of different managements for thrombus within filters were recorded and analyzed. RESULTS: During the study 764 patients having Aegisy Filters implanted were referred for filter removal, from which 236 cases (134 male patients, mean age 50.2 years) of thrombus within the filter were observed on initial pre-retrieval IVC venogram 12-39 days after insertion (average 16.9 days). The incidence of infra-filter thrombus was 30.9%, and complete occlusion of the filter bearing IVC was seen in 2.4% (18) of cases. Retrieval was attempted in all 121 cases with small clots using a regular snare and sheath technique, and was successful in 120. A total of 116 cases with massive thrombus and IVC occlusion by thrombus were treated by CDT and/or the new retrieval technique. Overall, 213 cases (90.3%) of thrombus in the filter were removed successfully without PE. CONCLUSIONS: A small thrombus within the filter can be safely removed without additional management. CDT for reduction of the clot burden in filters was effective and safe. Filter retrieval with manual negative pressure aspiration thrombectomy seemed reasonable and valuable for management of massive thrombus within filters in some patients. Full assessment of the value and safety of this technique requires additional studies. PMID- 27692533 TI - 18FDG-PET-CT improves specificity of preoperative lymph-node staging in patients with intestinal but not diffuse-type esophagogastric adenocarcinoma. AB - INTRODUCTION: The accuracy of preoperative lymph-node staging in patients with adenocarcinoma of the esophagogastric junction (AEG) or gastric cancer (GC) is low. The aim of this study was to assess the accuracy of [18F]fluorodeoxyglucose positron emission tomography/computed tomography (PET-CT) for lymph-node staging in patients with AEG or GC, with or without neoadjuvant treatment. PATIENTS AND METHODS: 221 consecutive patients with GC (n = 88) or AEG (n = 133) were evaluated. Initial staging included endoscopic ultrasound (EUS), multidetector spiral CT (MDCT) and PET-CT. PET-CT was performed for restaging in patients after neoadjuvant treatment (n = 94). Systematic lymphadenectomy was routinely performed with histopathological assessment of individual mediastinal and abdominal lymph-node stations. Preoperative staging from EUS, MDCT, and PET-CT was correlated with histopathological results. RESULTS: PET-CT showed a high specificity (91%) and positive predictive value (89%) for the preoperative detection of lymph-node metastases. In comparison, EUS was more sensitive (73% versus 50%, P < 0.01) but less specific (60%, P < 0.01). In patients with intestinal/mixed-type tumors, PET-CT improved the detection of extra-regional lymph-node metastases (P = 0.01) and distant metastases (P = 0.01) compared to CT alone. In contrast, lymph-node assessment by PET/CT after neoadjuvant treatment (32%, P < 0.01) and in diffuse-type cancers (24%, P < 0.01) is futile because of low sensitivities. CONCLUSION: PET-CT does not improve the overall accuracy of N staging, but does improve specificity compared to EUS and MDCT in AEG and GC. We do not recommend routine PET-CT for the initial staging in patients with diffuse type cancer or for restaging of lymph nodes after neoadjuvant treatment. PMID- 27692534 TI - Hepatic vascular inflow occlusion is associated with reduced disease free survival following resection of colorectal liver metastases. AB - BACKGROUND: Hepatic vascular inflow occlusion (VIO) can be applied during resection of colorectal liver metastases (CRLM) to control intra-operative blood loss, but has been linked to accelerated growth of micrometastases in experimental models. This study aimed to investigate the effects of hepatic VIO on disease-free and overall survival (DFS and OS) in patients following resection for CRLM. METHODS: All patients who underwent liver resection for CRLM between January 2006 and September 2015 at our center were analyzed. Hepatic VIO was performed if deemed indicated by the operating surgeon and severe ischemia was defined as >=20 min continuous or >=45 min cumulative intermittent VIO. Cox regression analysis was performed to identify predictive factors for DFS and OS. RESULTS: A total of 208 patients underwent liver resection for CRLM. VIO was performed in 64 procedures (31%), and fulfilled the definition of severe ischemia in 40 patients. Patients with severe ischemia had inferior DFS (5-year DFS 32% vs. 11%, P < 0.01), and inferior OS (5-year OS 37% vs. 64%, P < 0.01). At multivariate analysis, a high clinical risk score (Hazard ratio (HR) 1.60 (1.08 2.36)) and severe ischemia (HR 1.89 (1.21-2.97)) were independent predictors of worse DFS. Severe ischemia was not an independent predictor of OS. CONCLUSION: The present cohort study suggests that prolonged hepatic VIO during liver resection for CRLM was associated with reduced DFS. A patient-tailored approach seems advisable although larger studies should confirm these findings. PMID- 27692535 TI - Mortality, morbidity and healthcare expenditures after local tumour ablation or partial nephrectomy for T1A kidney cancer. AB - BACKGROUND: Local tumour ablation (LTA) may yield better perioperative outcomes than partial nephrectomy (PN), however the impact of each treatment on perioperative mortality and health care expenditures is unknown. The aim of the study was to compare mortality, morbidity and health care expenditures between LTA and PN. PATIENTS AND METHODS: A population-based assessment of 2471 patients with cT1a kidney cancer treated with either LTA or PN, between 2000 and 2009, in the SEER-Medicare database was performed. After propensity score matching, 30-day mortality, overall and specific complication rates, length of stay, readmission rates and health care expenditures according to LTA or PN were estimated. Multivariable logistic and linear models addressed the effect of each specific LTA approach on overall complication rates, length of stay, readmission rates and health care expenditures. RESULTS: The 30-day mortality was <2% after either LTA or PN (OR 2.27, p = 0.2). The overall complication rate was 21% after LTA and 40% after PN (OR 0.38, p < 0.001). Blood transfusions, infection/sepsis, wound infections, respiratory complications, gastrointestinal complications, acute kidney injury, and accidental puncture or laceration/foreign body left during procedure rates resulted lower after LTA relative to PN (all p < 0.05). Similarly, length of stay and health care expenditures resulted lower after LTA relative to PN (all p < 0.05). Conversely, readmission rate was not significantly different in LTA relative to PN (p = 0.1). CONCLUSIONS: Despite similar perioperative mortality, LTA is associated with lower complications rate, shorter length of stay and lower health care expenditure relative to PN. PMID- 27692536 TI - Sarcopenia in overweight and obese patients is a predictive factor for postoperative complication in gastric cancer: A prospective study. AB - BACKGROUND: Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength. This study aims to explore the prevalence of sarcopenia in overweight and obese gastric cancer (GC) patients and figured out the impacts of sarcopenia on the postoperative complication of overweight and obese GC patients. METHODS: According to the recommended body-mass index (BMI) for Asian populations by WHO, we conducted a prospective study of overweight and obese gastric cancer patients (BMI >= 23 kg/m2) under curative gastrectomy from August 2014 to December 2015. Including lumbar skeletal muscle index, handgrip strength and gait speed as the sarcopenic components were measured before surgery. Patients were followed up after gastrectomy to gain the actual clinical outcomes. Factors contributing to postoperative complications were analyzed by univariate and multivariate analysis. RESULTS: Total of 206 overweight or obese patients were enrolled in this study, 14 patients were diagnosed sarcopenia and were demonstrated having significantly association with higher risk of postoperative complications, higher hospital costs, and higher rate of 30-days readmission compared with the non-sarcopenic ones. On the basis of univariate and multivariate analysis, sarcopenia was an independent risk factor for postoperative complication of overweight and obese patients with gastric cancer (P = 0.002). CONCLUSION: Sarcopenia is an independent predictor of postoperative complications in overweight or obese patients with gastric cancer after radical gastrectomy. PMID- 27692537 TI - Assessment of environment impacts of egg production chain using life cycle assessment. AB - In this study we have to deal with the assessment of environment impacts of laying hen in the Alborz province, Iran. This assessment was carried out for one kg of egg during a period of 420 days for 1000 chickens. Then due to significant consumption of diet during period of question, three main products including corn, soybean and wheat which are consist of 80 percent of the combination of laying chicken diet, also collected the information about their production and it has been evaluated the indicators of their environment individually and eventually, the results has been considered as a title for inputs of poultry. Data for production of inputs were taken from EcoInvent 2.0 database, and SimaPro software was used for analysis. Ten classification impacts including Abiotic Depletion potential, Acidification potential, Eutrophication potential, Global Warming potential for time horizon 100 years, Ozone Depletion potential, Human Toxicity potential, Freshwater and Marine Aquatic Eco-toxicity potential, Terrestrial Eco-toxicity potential, and Photochemical Oxidation potential were selected based on the CML 2 baseline 2000 V2/world, 1990/characterization method. Due to the results, for each kilograms of egg, 30/09 MJ and also the value of greenhouse gas emissions is 4/07 Kg CO2 eq was calculated. According to the obtained results, the production of diet has made the most negative charge of environment among the inputs.

PMID- 27692540 TI - Sporadic inclusion body myositis misdiagnosed as idiopathic granulomatous myositis. AB - We present a case of a 65-year-old woman who was previously diagnosed with idiopathic granulomatous myositis and treated with immunosuppressive therapy for the next 10 years before a clinical diagnosis of inclusion body myositis was made. A review of the previously performed muscle biopsy showed most of the cardinal myopathologic features of sporadic inclusion body myositis, in addition to the granuloma. Her clinical course was strongly suggestive of inclusion body myositis with selective asymmetric weakness of forearm flexor muscles and quadriceps. This report highlights the importance of correlating clinical picture with muscle pathology changes along with judicious use of magnetic resonance imaging and serological studies to establish a definite diagnosis. PMID- 27692539 TI - Macrophage/monocyte-specific deletion of Ras homolog gene family member A (RhoA) downregulates fractalkine receptor and inhibits chronic rejection of mouse cardiac allografts. AB - BACKGROUND: The cellular and molecular mechanisms of chronic rejection of transplanted organs remain obscure; however, macrophages are known to play a critical role in the injury and repair of allografts. Among multiple factors influencing macrophage infiltration to allografts, the fractalkine chemokine (C X3-C motif) ligand 1(CX3CL1)/chemokine (C-X3-C motif) receptor 1 (CX3CR1) signaling pathway and actin cytoskeleton, which is regulated by a small guanosine 5'-triphosphatase Ras homolog gene family member A (RhoA), are of the utmost importance. To define the role of macrophage/RhoA pathway involvement in chronic rejection, we generated mice with monocyte/macrophage-specific deletion of RhoA. METHODS: Hearts from BALB/c (H-2d) donors were transplanted into RhoAflox/flox (no Cre) and heterozygous Lyz2Cre+/-RhoAflox/flox recipients treated with cytotoxic T-lymphocyte-associated protein 4 immunoglobulin to inhibit early T cell response. Allografts were assessed for chronic rejection and monocyte/macrophage functions. RESULTS: The deletion of RhoA inhibited macrophage infiltration, neointimal hyperplasia of vasculature, and abrogated chronic rejection of the allografts. The RhoA deletion downregulated G protein-coupled fractalkine receptor CX3CR1, which activates the RhoA pathway and controls monocyte/macrophage trafficking into the vascular endothelium. This in turn promotes, through overproliferation and differentiation of smooth muscle cells in the arterial walls, neointimal hyperplasia. CONCLUSIONS: Our finding of codependence of chronic rejection on monocyte/macrophage CX3CR1/CX3CL1 and RhoA signaling pathways may lead to the development of novel anti-chronic rejection therapies.

PMID- 27692544 TI - School-Based Health Centers' Presence: The Role of School and Community Factors. AB - INTRODUCTION: School-based health centers (SBHCs) offer an efficient mechanism for delivering health services to large numbers of underserved youth; however, their availability varies across communities. Data on sociocontextual variables were analyzed to investigate factors that inhibit and facilitate SBHCs. METHODS: Secondary data from 2012 to 2015 state databases were linked to examine the association between SBHCs' presence in California high schools and demand, resource, and political conservatism at the school and community levels that may influence where SBHCs are located and the number of provided health services. Data were analyzed in 2015 using hierarchical binary and Poisson models. RESULTS: Presence of a local non-school-based family planning clinic was the strongest correlate of SBHC presence. School size, percentage non-white, and percentage receiving free or reduced-price lunches were positively associated with SBHC presence. Percentage who voted Republican in the 2012 general election and teen pregnancy rates were negatively associated with SBHC presence. None of the predictors were associated with number of services provided by SBHCs. CONCLUSIONS: School and community factors appear to play a role in supporting or impeding the establishment of SBHCs. In addition to variables tapping communities' need for and resources available to support SBHCs, political conservatism appears to affect SBHC availability. SBHC advocates can use this information to understand where opportunities for growth might exist, identify collaborative partners, and prepare for challenges to supporting new SBHCs. Researchers may also use this information in evaluation studies to control for school-level confounders and develop appropriate comparison samples through matching procedures.

AB - INTRODUCTION: The relationship between low income and worse health outcomes is evident, yet its association with cognitive outcomes is less explored. Most studies have measured income at one time and none have examined how sustained exposure to low income influences cognition in a relatively young cohort. This study examined the effect of sustained poverty and perceived financial difficulty on cognitive function in midlife. METHODS: Income data were collected six times between 1985 and 2010 for 3,383 adults from the Coronary Artery Risk Development in Young Adults prospective cohort study. Sustained poverty was defined by the percentage of time participants' household income was <200% of the federal poverty level-"never" in poverty, "0< to <1/3," ">=1/3 to <100%" or "all-time." In 2010, at a mean age of 50 years, participants underwent a cognitive battery. Data were analyzed in 2015. RESULTS: In demographic-adjusted linear regression models, individuals with all-time poverty performed significantly worse than individuals never in poverty: 0.92 points worse on verbal memory (z-score, -0.28; 95% CI=-0.43, -0.13), 11.60 points worse on processing speed (z-score, -0.72; 95% CI=-0.85, -0.58), and 3.50 points worse on executive function (z-score, -0.32; 95% CI=-0.47, -0.17). Similar results were observed with perceived financial difficulty. Findings were robust when restricted to highly educated participants, suggesting little evidence for reverse causation. CONCLUSIONS: Cumulative exposure to low income over 2 decades was strongly associated with worse cognitive function of a relatively young cohort. Poverty and perceived hardship may be important contributors to premature aging among disadvantaged populations. PMID- 27692546 TI - Identification of methionine aminopeptidase 2 as a molecular target of the organoselenium drug ebselen and its derivatives/analogues: Synthesis, inhibitory activity and molecular modeling study. AB - A collection of twenty-six organoselenium compounds, ebselen and its structural analogues, provided a novel approach for inhibiting the activity of human methionine aminopeptidase 2 (MetAP2). This metalloprotease, being responsible for the removal of the amino-terminal methionine from newly synthesized proteins, plays a key role in angiogenesis, which is essential for the progression of diseases, including solid tumor cancers. In this work, we discovered that ebselen, a synthetic organoselenium drug molecule with anti-inflammatory, anti oxidant and cytoprotective activity, inhibits one of the main enzymes in the tumor progression pathway. Using three-step synthesis, we obtained twenty-five ebselen derivatives/analogues, ten of which are new, and tested their inhibitory activity toward three neutral aminopeptidases (MetAP2, alanine and leucine aminopeptidases). All of the tested compounds proved to be selective, slow binding inhibitors of MetAP2. Similarly to ebselen, most of its analogues exhibited a moderate potency (IC50=1-12MUM). Moreover, we identified three strong inhibitors that bind favorably to the enzyme with the half maximal inhibitory concentration in the submicromolar range. PMID- 27692545 TI - Design, synthesis, and biological evaluation of alpha-hydroxyacyl-AMS inhibitors of amino acid adenylation enzymes. AB - Biosynthesis of bacterial natural-product virulence factors is emerging as a promising antibiotic target. Many such natural products are produced by nonribosomal peptide synthetases (NRPS) from amino acid precursors. To develop selective inhibitors of these pathways, we have previously described aminoacyl AMS (sulfamoyladenosine) macrocycles that inhibit NRPS amino acid adenylation domains but not mechanistically-related aminoacyl-tRNA synthetases. To improve the cell permeability of these inhibitors, we explore herein replacement of the alpha-amino group with an alpha-hydroxy group. In both macrocycles and corresponding linear congeners, this leads to decreased biochemical inhibition of the cysteine adenylation domain of the Yersina pestis siderophore synthetase HMWP2, which we attribute to loss of an electrostatic interaction with a conserved active-site aspartate. However, inhibitory activity can be regained by installing a cognate beta-thiol moiety in the linear series. This provides a path forward to develop selective, cell-penetrant inhibitors of the biosynthesis of virulence factors to probe their biological functions and potential as therapeutic targets. PMID- 27692547 TI - Synthesis and activity of newly designed aroxyalkyl or aroxyethoxyethyl derivatives of piperazine on the cardiovascular and the central nervous systems. AB - In the search for new hypotensive agents some new aroxyalkyl or aroxyethoxyethyl derivatives of piperazine have been synthesized and evaluated for their pharmacological properties. Pharmacological tests included receptor binding assays toward adrenergic receptors alpha1, alpha2 and beta1, additionally 5-HT1A, functional bioassay and in vivo evaluation of hypotensive activity as well as antidepressant-like potential. All the tested compounds exhibited alpha1 antagonistic properties, three of them possessed also hypotensive activity in rats. The most promising compound 3 1-[4-(2,6-dimethylphenoxy)butyl]-4-(2 methoxyphenyl)piperazine hydrochloride was a selective alpha1 receptor antagonist (Ki=23.5+/-1.3, alpha1/alpha2=15.77, pKB=8.538+/-0.109). It was active in all tested doses in vivo (1, 0.5, and 0.1mg/kg) and it reduced blood pressure by 10 13% at the dose of 1mg/kg (rats, i.v.). Compound 5 1-[2-(2,3 dimethylphenoxy)ethoxyethyl]-4-(2-methoxyphenyl)piperazine dihydrochloride exhibited the lowest dose for antidepressant-like activity 5mg/kgb.w. (mice, i.p.) without influence on spontaneous activity (mice, i.p.). PMID- 27692548 TI - When in infancy does the "fear bias" develop? AB - Much research has focused on how infants respond to emotional facial expressions. One of the key findings in this area of research is that by 7months of age, but not younger, infants show a bias in processing fearful faces even when compared with other negative and novel facial expressions. A recent study by Heck and colleagues (Journal of Experimental Child Psychology, 2016, Vol. 147, pp. 100 110) challenges this idea by showing that 5-month-olds looked longer at fearful faces than at happy and at neutral faces when dynamic displays (videos) are used. Given that previous work failed to find enhanced attention to fearful faces in 5 month-olds using static displays (photographs), this was taken as evidence that biased attention to fear can be observed earlier when dynamic information is presented. However, we computed an analysis indicating that the overall amount of motion displayed in the videos in Heck and colleagues' study is confounded with emotion such that the greatest amount of motion is evident in the fearful face videos and may have driven infants' looking patterns. We discuss these findings and their limitations in the context of other research using dynamic emotion stimuli. Although these findings do not rule out the possibility that 5-month olds are sensitive to fear, we stress the need to control for physical differences such as motion before any conclusions regarding the emergence of the fear bias during infancy can be drawn and in order to improve research practice in the field. PMID- 27692549 TI - [A pseudotumoral lesion revealing Meckel's diverticulum]. AB - INTRODUCTION: Meckel's diverticulum is a common malformation in children, usually asymptomatic, with complications in only 20% of cases. Exceptionally, a tumor can develop in Meckel's diverticulum in children, particularly Burkitt's lymphoma; in adults it can develop into a gastrointestinal stromal tumor, a leiomyosarcoma, or a neuroendocrine tumor such as a carcinoid tumor. The diagnosis of inflammatory pseudotumor following an insidious perforation is rare. OBSERVATION: We report the case of a 14-month-old boy who presented with fever, asthenia, food refusal, and digestive complaints such as vomiting and tender abdomen suggesting appendicitis. Computed tomography showed an ileal mass of 3cm in diameter, which led to the suspicion of Burkitt's lymphoma. Laparoscopy showed Meckel's diverticulum with a mass of 3*2.8*2cm. Histological examination confirmed the diagnosis of Meckel's diverticulum with gastric heterotopia and showed a proliferation of spindle cells in a myxoid background, with an inflammatory infiltrate made of lymphocytes and plasmocytes. Immunostaining ruled out a malignant tumor. The diagnosis of an inflammatory pseudotumor developing on a Meckel diverticulum with gastric heterotopias was made. The outcome was favorable after surgical resection. CONCLUSION: While perforation of a Meckel diverticulum with gastric heterotopia is a common finding, the discovery of an inflammatory pseudotumor following a perforation is rare; the differential diagnosis should include Burkitt's lymphoma.

AB - OBJECTIVES: To study and describe the psychological responses (depression and anxiety), the coping strategies, and the impact of sickle cell disease on the quality of life (QOL) of mothers. PATIENTS AND METHODS: A cross-sectional study of mothers with affected children was conducted at the university hospital center of Brazzaville, between February and April 2014. Hamilton and Beck scales, the Brief-COPE, and the Short Form Health Survey were used to assess anxiety, depression, coping strategies, and QOL, respectively. RESULTS: In all, 104 mothers of children with sickle cell disease were surveyed. Of the subjects, 73 (70.2%) had depression and 85 (81.7%) anxiety, while 19 (18.3%) mothers were neither anxious nor depressed. The study shows that depression occurred more often among mothers whose children presented with at least three vaso-occlusive crises (CVO) requiring hospitalization per year (OR=5.1; range=1.8-13.9), at least one blood transfusion (OR=6; range=2.3-15.5), and those whose disease had been known for at least 5 years (OR=3; range=1.2-7.2). On the contrary, maternal anxiety was influenced only by the number of transfusions and CVO requiring hospitalization. The main coping strategy was religious coping (65.4%) followed by acceptance (60%). The QOL of mothers with affected children was impaired in 56.7% of cases. Altered QOL was related to the number of hospitalized CVO per year, i.e., equal to or greater than 3 (OR=6.5; range=2.1-19.6 [P<0.01]), and the number of blood transfusions equal to or greater than 1 (OR=2.9; range=1.2-7.3 [P<0.025]). CONCLUSION: Sickle cell disease is a heavy burden for mothers caring for these children. Mental health disorders are present at the time of diagnosis and in everyday life.

It is one of the most frequently performed surgical procedures around the world. This practice primarily involves minors. The aim of this study was to review the legal aspects of ritual circumcision in France. We report the cases of an 11-year-old and a 15-year-old boy examined in the forensic unit at the Hotel-Dieu hospital in Paris, after their father complained to the Minors Protection Brigade of Paris following the discovery of their circumcision. The examination conducted in the forensic unit found that the two boys had undergone recent circumcision. The total incapacity of work (ITT) was assessed as 5 days for the 15-year-old boy and 1 day for the 11-year-old boy. Ritual "medicalized" circumcision is legal in France, and does not fall under article 222-1 of the Criminal Code (torture and acts of barbarism) or article 16-1 of the Civil Code (inviolability of the human body). Circumcision is treated as a "serious act" by several areas of jurisprudence, which means it is imperative to obtain the consent of both parents. Moreover, it must be performed in a hospital by knowledgeable staff. PMID- 27692552 TI - [Desmoid tumors in an adolescent girl with familial adenomatous polyposis]. AB - Desmoid tumors (DT) are rare and nonmetastasizing fibroblastic neoplasms, characterized by local invasiveness. They occur sporadically or arise in the context of familial adenomatous polyposis (FAP; 5-10% of cases). Most cases develop sporadically in young adults, but some cases also occur in children. We report the case of an adolescent girl with FAP and DT, and we discuss the therapeutic strategies. An adolescent girl with FAP underwent surgery at the age of 14 years with total proctocolectomy. She had a neo-mutation in the APC gene at codon 1068, which is not usually associated with DT. Three years later, she had painful defecations. Imaging showed two abdominal DT. After a multidisciplinary team meeting, the patient was refused for surgery, and medical treatment with antihormonal agents and nonsteroidal anti-inflammatory drugs was started. Imaging 18 months later showed DT stabilization, but the patient had difficulties to control chronic pains, which required morphine treatment, hypnotic sessions, and transcutaneous electric nerve stimulation. This case highlights the importance of DT screening in patients with FAP, mainly after surgery, regardless of their age and genetic mutation. Progress remains to be made in determining DT risk factors and in developing treatment. DT are still difficult to cure because of their potential for local invasion and local recurrence, and need to be managed by a multidisciplinary team. PMID- 27692553 TI - [Accidental mercury poisoning in a 12-year-old girl]. AB - INTRODUCTION: Exposure to metallic mercury can cause severe accidental intoxications in children, whose clinical symptoms can vary depending on the route of administration, the dose, as well as the time and duration of the exposure. It has become unusual in France, yet it must be considered when taking a patient's medical history in cases of multisystemic involvement without a clear explanation. CLINICAL CASE: We report the case of a 12-year-old patient hospitalized because of a cough, poor general condition, chills, night sweats, psychomotor retardation, and skin lesions that had been developing for several weeks. The initial clinical examination also revealed sinus tachycardia, arterial hypertension, and abolition of osteotendinous reflexes. Complementary examination results were normal apart from a glomerular proteinuria without renal failure. When interviewing the mother, she reported that the child had played with mercury balls 3 months earlier. The suspicion of poisoning was confirmed by blood and urine analysis as well as renal biopsy showing an aspect of membranous glomerulonephritis with IgG and C3 depositions. An intoxication via a transdermal route being unlikely on healthy skin, the Regional Health Agency's survey concluded that chronic intoxication had occurred by inhalation of the mercury spread on the floor at the time of the exposure, which was then vacuum cleaned and released again by the contaminated vacuum cleaner. The patient's outcome was favorable within a few weeks after initiating DMSA chelation therapy. CONCLUSION: Mercury poisoning should be considered in cases of a multisystemic disorder without clear explanation, in order to intervene quickly and thus prevent irreversible renal and neurological consequences. PMID- 27692554 TI - Optimize CA19-9 in detecting pancreatic cancer by Lewis and Secretor genotyping. AB - BACKGROUND: Carbohydrate antigen 19-9 (CA19-9) is currently the most widely used biomarker for pancreatic cancer. It is well-known that Lewis and Secretor status can affect CA19-9 biosynthesis. This study was performed to optimize CA19-9 in detecting pancreatic cancer using Lewis and Secretor dependent cut-off values. METHODS: Lewis and Secretor genotypes were determined by Sanger sequencing in a large cohort of subjects (578 cases with pancreatic cancer, 210 cases with benign pancreatic disease, 315 normal subjects). The effectiveness of CA19-9 for detecting pancreatic cancer using Lewis and Secretor group dependent cut-off values was evaluated. RESULTS: The Lewis (-), Mixed, and Secretor (-) groups had low, medium, and high CA19-9 biosynthesis, respectively. In Lewis (-) pancreatic cancer (all stages), CA19-9 had a sensitivity of 48.6% and a specificity of 95.9% when 1.8 U/mL was used as the cut-off value. The sensitivity of CA19-9 in detecting all stages of pancreatic cancer improved from 80.1% to 88.0% and the negative predictive value increased from 81.2% to 87.1% without compromising other values when using group dependent cut-off values. The sensitivity of CA19-9 for the detection of stage I, II pancreatic cancer increased from 76.1% to 87.2%. CONCLUSIONS: The value of CA19-9 in detecting pancreatic cancer was optimized by using group dependent cut-off values based on Lewis and Secretor genotypes. CA19 9 can be applied as an early detector of pancreatic cancer using group dependent cut-off values. PMID- 27692555 TI - Matrix metalloproteinase inhibitor modulates esterase-catalyzed degradation of resin-dentin interfaces. AB - OBJECTIVE: Assess the modulating effect of matrix metalloproteinase (MMP) inhibition on simulated human salivary enzyme (SHSE)-catalyzed degradation of interfacial fracture-toughness (FT) of self-etched and total-etched resin-dentin interfaces. METHODS: Miniature short-rod FT specimens (N=10/group) containing a resin composite bonded to human dentin, using a self-etch (Easy Bond, EB) or a total-etch (Scotchbond, SB) adhesives, were prepared with and without application of an MMP inhibitor (galardin). Specimens were non-incubated or incubated in phosphate buffered saline (PBS) or SHSE for 7, 30, 90, or 180-days. FT data were obtained using a universal testing machine. Incubation media were analyzed by high performance liquid chromatography (HPLC) for the presence of a 2,2-bis-[4 2(2-hydroxy-3-methacryloxypropoxy)phenyl]-propane (bisGMA)-derived degradation product, bis-hydroxy-propoxy-phenyl-propane (bisHPPP). Fractographic analysis was performed by scanning electron microscopy and image processing software (ImageJ). Statistical analysis was performed by ANOVA and Tukey's (p<0.05). RESULTS: More bisHPPP was detected in SHSE vs. PBS for both adhesive systems (p<0.05). EB specimens yielded no difference in FT and failed preferentially in the resin after >30-days (p<0.05). SB specimens yielded lower FT values after 180-days with SHSE +/-galardin vs. 0-days/no-galardin (p<0.05) and failed preferentially in the hybrid-layer after >30-days (p<0.05). Galardin mildly modulated the change in fracture mode for both systems. SIGNIFICANCE: Esterase-catalyzed degradation of total-etch interfaces is modulated by MMP-inhibition, however, self-etch interfaces possess greater biostability under simulated intra-oral conditions, regardless of MMP inhibition. This could be related to different chemical compositions and/or mode of adhesion. PMID- 27692556 TI - Long-term Survival Analysis of Meniscus Allograft Transplantation With Bone Fixation. AB - PURPOSE: To investigate the long-term clinical results and clinical survival rate of meniscus allograft transplantation (MAT) with bone fixation. METHODS: The inclusion criteria of this study were previous MAT with bone fixation technique in our institution and minimum follow-up duration of 8 years. Potential subjects were identified using the medical records and database that was prospectively collected from December 1996 to December 2005. The exclusion criteria were diffuse International Cartilage Repair Society grade IV articular cartilage degeneration that was not treated with a concomitant or staged cartilage repair procedure. Surgical indication for MAT was previous total or subtotal meniscectomy followed by persistent swelling and pain in involved compartment. Recommendations to return to contact sports or strenuous activities were not made. Clinical outcomes were evaluated using the modified Lysholm score, and comparison between preoperative and final Lysholm score was done using Student t test. During the follow-up period, failure was defined as (1) subtotal resection of the allograft, (2) conversion to total knee arthroplasty, or (3) a modified Lysholm score less than 65 or that of the preoperative status. Survival analysis was performed using the Kaplan-Meier method. RESULTS: During the study period, 52 knees underwent MAT in our institution and 49 knees were eligible for this study. Three knees were excluded because they had diffuse grade IV cartilage degeneration in the respective compartment. Among the 49 knees enrolled, 34 underwent lateral and 15 underwent medial MAT. Two patients had bilateral lateral MAT. Of those 47 patients, 37 were male and 10 were female. Mean patient age at the time of the MAT was 30.4 +/- 8.6 years. The median follow-up period was 11.5 years (8 to 17 years). The preoperative mean modified Lysholm score was 73.2 +/- 10.6, which significantly increased to 89.4 +/- 13.2 at the time of the final follow-up (P < .001). There were 2 failures noted at 6 months and 11.3 years, respectively, after MAT. All of the other allografts were surviving at the time of the latest follow-up. The 10-year survival rate was 98.0% (95% confidence interval [CI], 94.1%-100%), and the 15-year survival rate was 93.3% (95% CI, 83.7%-100%) according to the Kaplan-Meier analysis. CONCLUSIONS: MAT using the bone fixation techniques demonstrated a high clinical survival rate according to the long-term observation. LEVEL OF EVIDENCE: Level IV, therapeutic case series. PMID- 27692557 TI - The Development of a Xenograft-Derived Scaffold for Tendon and Ligament Reconstruction Using a Decellularization and Oxidation Protocol. AB - PURPOSE: To evaluate the biological, immunological, and biomechanical properties of a scaffold derived by architectural modification of a fresh-frozen porcine patella tendon using a decellularization protocol that combines physical, chemical, and enzymatic modalities. METHODS: Porcine patellar tendons were processed using a decellularization and oxidation protocol that combines physical, chemical, and enzymatic modalities. Scaffolds (n = 88) were compared with native tendons (n = 70) using histologic, structural (scanning electron microscopy, porosimetry, and tensile testing), biochemical (mass spectrometry, peracetic acid reduction, DNA quantification, alpha-galactosidase [alpha-gal] content), as well as in vitro immunologic (cytocompatibility, cytokine induction) and in vivo immunologic nonhuman primate analyses. RESULTS: A decrease in cellularity based on histology and a significant decrease in DNA content were observed in the scaffolds compared with the native tendon (P < .001). Porosity and pore size were increased significantly (P < .001). Scaffolds were cytocompatible in vitro. There was no difference between native tendons and scaffolds when comparing ultimate tensile load, stiffness, and elastic modulus. The alpha-gal xenoantigen level was significantly lower in the decellularized scaffold group compared with fresh-frozen, nondecellularized tissue (P < .001). The in vivo immunological response to implanted scaffolds measured by tumor necrosis factor-alpha and interleukin-6 levels was significantly (P < .001) reduced compared with untreated controls in vitro. These results were confirmed by an attenuated response to scaffolds in vivo after implantation in a nonhuman primate model. CONCLUSIONS: Porcine tendon was processed via a method of decellularization and oxidation to produce a scaffold that possessed significantly less inflammatory potential than a native tendon, was biocompatible in vitro, of increased porosity, and with significantly reduced amounts of alpha gal epitope while retaining tensile properties. CLINICAL RELEVANCE: Porcine derived scaffolds may provide a readily available source of material for musculoskeletal reconstruction and repair while eliminating concerns regarding disease transmission and the morbidity of autologous harvest. PMID- 27692558 TI - Impact of omega-3 polyunsaturated fatty acids on vascular function and blood pressure: Relevance for cardiovascular outcomes. AB - AIMS: To overview the effects of omega-3 polyunsaturated fatty acids (PUFA) on blood vessels and blood pressure (BP) and their relevance for cardiovascular prevention. DATA SYNTHESIS: The importance of omega-3 PUFA for the cardiovascular system has come under the spotlight during the last decades. These fatty acids are present in variable amounts in cell membranes of mammal species, and their content affects a variety of cellular functions. Evidence obtained in animal and human studies suggests that omega-3 PUFA affect many steps of the atherosclerotic process. In blood vessels, omega-3 PUFA improve endothelial function; promote vasodilatation through relaxation of smooth muscle cells; exert antioxidant, anti inflammatory, and antithrombotic actions; delay development of plaques and increase their stability; and decrease wall stiffening. Omega-3 PUFA might affect BP, and studies conducted with ambulatory monitoring suggest that supplementation with these fatty acids decreases the average 24-h BP levels. This effect on BP is related to the pretreatment membrane content of omega-3 PUFA, and this might explain some inconsistencies among intervention trials. Meta-analyses indicate that omega-3 PUFA have a mild but significant BP lowering effect. While encouraging results were initially obtained with the use of omega-3 PUFA supplements in secondary prevention trials, meta-analyses have not confirmed the ability of these fatty acids to decrease the risk of coronary heart and cerebrovascular disease. CONCLUSIONS: Omega-3 PUFA are associated with significant improvement in vascular function and lowering of BP. However, the evidence currently supporting the role of these fatty acids in cardiovascular prevention is weak and needs further investigation. PMID- 27692559 TI - Human parainfluenza virus-3 can be targeted by rapidly ex vivo expanded T lymphocytes. AB - BACKGROUND AIMS: Human parainfluenza virus-3 (HPIV) is a common cause of respiratory infection in immunocompromised patients and currently has no effective therapies. Virus-specific T-cell therapy has been successful for the treatment or prevention of viral infections in immunocompromised patients but requires determination of T-cell antigens on targeted viruses. METHODS: HPIV3 specific T cells were expanded from peripheral blood of healthy donors using a rapid generation protocol targeting four HPIV3 proteins. Immunophenotyping was performed by flow cytometry. Viral specificity was determined by interferon (IFN) gamma ELISpot, intracellular cytokine staining and cytokine measurements from culture supernatants by Luminex assay. Cytotoxic activity was tested by 51Cr release and CD107a mobilization assays. Virus-specific T cells targeting six viruses were then produced by rapid protocol, and the phenotype of HPIV3-specific T cells was determined by immunomagnetic sorting for IFN-gamma-producing cells. RESULTS: HPIV3-specific T cells were expanded from 13 healthy donors. HPIV3 specific T cells showed a CD4+ predominance (mean CD4:CD8 ratio 2.89) and demonstrated specificity for multiple HPIV3 antigens. The expanded T cells were polyfunctional based on cytokine production but only had a minor cytotoxic component. T cells targeting six viruses in a single product similarly showed HPIV3 specificity, with a predominant effector memory phenotype (CD3+/CD45RA /CCR7-) in responder cells. DISCUSSION: HPIV3-specific T cells can be produced using a rapid ex vivo protocol from healthy donors and are predominantly CD4+ T cells with Th1 activity. HPIV3 epitopes can also be successfully targeted alongside multiple other viral epitopes in production of six-virus T cells, without loss of HPIV3 specificity. These products may be clinically beneficial to combat HPIV3 infections by adoptive T-cell therapy in immune-compromised patients. PMID- 27692560 TI - Intake of different types of dairy and its prospective association with risk of type 2 diabetes: The Rotterdam Study. AB - BACKGROUND AND AIMS: The prevalence of type 2 diabetes (T2DM) is increasing. Several studies have suggested a beneficial effect of several major dairy nutrients on insulin production and sensitivity. Conversely, harmful effects have been suggested as well. This study aimed to investigate the impact of the full range of dairy products and its association with incidence T2DM in Dutch adults aged >=55 years participating in the Rotterdam Study. METHODS AND RESULTS: Dairy intake was assessed with a validated FFQ, including total, skimmed, semi-skimmed, full-fat, fermented, and non-fermented dairy, and subclasses of these product groups. Verified prevalent and incident diabetes were documented. Cox proportional hazards regression and spline regression were used to analyse data, adjusting for age, sex, alcohol, smoking, education, physical activity, body mass index, intake of total energy, energy-adjusted meat, and energy-adjusted fish intake. Median total dairy intake was 398 g/day (IQR 259-559 g/day). Through 9.5 +/- 4.1 years of follow-up, 393 cases of incident T2DM were reported. Cox and spline regression did not point towards associations of total dairy consumption, dairy consumption based on fat content, non-fermented or fermented dairy consumption, or individual dairy product consumption with incident T2DM. The HR for total dairy intake and T2DM was 0.93 (95% CI: 0.70-1.23) in the upper quartile (P-for trend 0.76). CONCLUSIONS: This prospective cohort study did not point towards an association between dairy consumption and T2DM. PMID- 27692561 TI - Renal perfusion in sepsis: from macro- to microcirculation. AB - The pathogenesis of sepsis-associated acute kidney injury is complex and likely involves perfusion alterations, a dysregulated inflammatory response, and bioenergetic derangements. Although global renal hypoperfusion has been the main target of therapeutic interventions, its role in the development of renal dysfunction in sepsis is controversial. The implications of renal hypoperfusion during sepsis probably extend beyond a simple decrease in glomerular filtration pressure, and targeting microvascular perfusion deficits to maintain tubular epithelial integrity and function may be equally important. In this review, we provide an overview of macro- and microcirculatory dysfunction in experimental and clinical sepsis and discuss relationships with kidney oxygenation, metabolism, inflammation, and function. PMID- 27692562 TI - Rhein reverses Klotho repression via promoter demethylation and protects against kidney and bone injuries in mice with chronic kidney disease. AB - Rhein is an anthraquinone compound isolated from the medicinal plant rhubarb and mainly used in the clinical treatment of diabetic nephropathy. Rhein exhibits various renoprotective functions, but the underlying mechanisms are not fully determined. However, its renoprotective properties recapitulate the role of Klotho, a renal-specific antiaging protein critical for maintaining kidney homeostasis. Here we explored the connections between rhein renoprotection and Klotho in a mouse model of adenine-induced chronic kidney disease. In addition to being an impressive Klotho upregulator, rhein remarkably reversed renal Klotho deficiency in adenine-treated mice. This effect was associated with significant improvement in disturbed serum biochemistry, profibrogenic protein expression, and kidney and bone damage. Further investigation of the molecular basis of Klotho loss revealed that these kidneys displayed marked inductions of DNA methyltransferase DNMT1/DNMT3a and Klotho promoter hypermethylation, whereas rhein treatment effectively corrected these alterations. The renal protective effects of rhein were largely abolished when Klotho was knocked-down by RNA interferences, suggesting that rhein reversal of Klotho deficiency is essential for its renoprotective actions. Thus, our study clarifies how rhein regulation of Klotho expression contributes to its renoprotection and brings new insights into Klotho-targeted strategy for the treatment of kidney diseases of various etiologies. PMID- 27692563 TI - Low-dose hydralazine prevents fibrosis in a murine model of acute kidney injury to-chronic kidney disease progression. AB - Acute kidney injury (AKI) and progressive chronic kidney disease (CKD) are intrinsically tied syndromes. In this regard, the acutely injured kidney often does not achieve its full regenerative capacity and AKI directly transitions into progressive CKD associated with tubulointerstitial fibrosis. Underlying mechanisms of such AKI-to-CKD progression are still incompletely understood and specific therapeutic interventions are still elusive. Because epigenetic modifications play a role in maintaining tissue fibrosis, we used a murine model of ischemia-reperfusion injury to determine whether aberrant promoter methylation of RASAL1 contributes causally to the switch between physiological regeneration and tubulointerstitial fibrogenesis, a hallmark of AKI-to-CKD progression. It is known that the antihypertensive drug hydralazine has demethylating activity, and that its optimum demethylating activity occurs at concentrations below blood pressure-lowering doses. Administration of low-dose hydralazine effectively induced expression of hydroxylase TET3, which catalyzed RASAL1 hydroxymethylation and subsequent RASAL1 promoter demethylation. Hydralazine-induced CpG promoter demethylation subsequently attenuated renal fibrosis and preserved excretory renal function independent of its blood pressure-lowering effects. In comparison, RASAL1 demethylation and inhibition of tubulointerstitial fibrosis was not detected upon administration of the angiotensin-converting enzyme inhibitor Ramipril in this model. Thus, RASAL1 promoter methylation and subsequent transcriptional RASAL1 suppression plays a causal role in AKI-to-CKD progression. PMID- 27692564 TI - Release of extracellular DNA influences renal ischemia reperfusion injury by platelet activation and formation of neutrophil extracellular traps. AB - Acute kidney injury is often the result of ischemia reperfusion injury, which leads to activation of coagulation and inflammation, resulting in necrosis of renal tubular epithelial cells. Platelets play a central role in coagulation and inflammatory processes, and it has been shown that platelet activation exacerbates acute kidney injury. However, the mechanism of platelet activation during ischemia reperfusion injury and how platelet activation leads to tissue injury are largely unknown. Here we found that renal ischemia reperfusion injury in mice leads to increased platelet activation in immediate proximity of necrotic cell casts. Furthermore, platelet inhibition by clopidogrel decreased cell necrosis and inflammation, indicating a link between platelet activation and renal tissue damage. Necrotic tubular epithelial cells were found to release extracellular DNA, which, in turn, activated platelets, leading to platelet granulocyte interaction and formation of neutrophil extracellular traps ex vivo. Renal ischemia reperfusion injury resulted in increased DNA-platelet and DNA platelet-granulocyte colocalization in tissue and elevated levels of circulating extracellular DNA and platelet factor 4 in mice. After renal ischemia reperfusion injury, neutrophil extracellular traps were formed within renal tissue, which decreased when mice were treated with the platelet inhibitor clopidogrel. Thus, during renal ischemia reperfusion injury, necrotic cell-derived DNA leads to platelet activation, platelet-granulocyte interaction, and subsequent neutrophil extracellular trap formation, leading to renal inflammation and further increase in tissue injury.

AB - Approximately 40% to 80% of patients receiving pertuzumab-directed therapy for human epidermal growth factor receptor 2 (HER2)-positive breast cancer will develop chemotherapy-induced diarrhea (CID). Loperamide and octreotide are frequently used to treat CID after diarrhea occurs, but neither is used prophylactically or targets the underlying mechanism. Previous studies suggest blocking epidermal growth factor receptor may cause excess chloride secretion, resulting in diarrhea. Crofelemer is derived from the red latex of the Croton lechleri tree, blocks gastrointestinal cystic fibrosis transmembrane regulator and calcium-activated chloride channels, and is U.S. Food and Drug Administration approved for relief of diarrhea in HIV/AIDS patients on anti-retroviral therapy. Crofelemer is not systemically absorbed, has relatively few side effects, and presents a targeted approach at preventing CID in patients receiving pertuzumab based therapy. HALT-D (DiarrHeA Prevention and ProphyLaxis with Crofelemer in HER2-Positive Breast Cancer Patients Receiving Trastuzumab, Pertuzumab, and Docetaxel or Paclitaxel with or without Carboplatin, NCT02910219) is a phase II, randomized, open-label trial that aims to recruit 46 patients from 3 MedStar sites. Adults with HER2-positive breast cancer being treated with trastuzumab, pertuzumab, and docetaxel or paclitaxel (THP) or trastuzumab, pertuzumab, docetaxel, and carboplatin (TCHP) will be randomized to receive crofelemer or no medication for diarrhea prophylaxis. The primary endpoint is incidence of all grade diarrhea for >= 2 consecutive days during cycles 1 to 2 of THP or TCHP. Secondary endpoints include overall incidence, duration, and severity of diarrhea; time to onset of diarrhea; use of other anti-diarrheal medications; stool frequency and consistency; and quality of life. HALT-D will provide important information about the feasibility and tolerability of crofelemer in preventing diarrhea for patients receiving THP or TCHP.

AB - BACKGROUND: The treatment strategy for in-stent restenosis (ISR) with bifurcation lesions has not been well explored. We examined the clinical outcomes between final kissing balloon technique (FKBT) after stent implantation and single-stent implantation without FKBT for bifurcation ISR lesions. METHODS: We identified 115 consecutive ISR with bifurcation lesions among 108 patients who underwent drug eluting stent implantation. The patients were divided into the FKBT group (34 patients, 35 lesions) and the non-FKBT group (74 patients, 80 lesions). RESULTS: Thrombolysis in myocardial infarction flow grade of side branch was significantly greater in the patients with FKBT than those without FKBT after coronary intervention (2.80+/-0.46 vs. 2.65+/-0.68, p=0.04), but this difference was attenuated and was no longer statistically significant at the time of follow-up (2.80+/-0.48 vs. 2.80+/-0.60, p=0.97). During a mean follow-up of 47.8+/-23.6 months, there were no significant differences in the incidence of major adverse cardiac events (MACE). In multivariate analysis, estimated glomerular filtration rate (hazard ratio: 0.96, 95% confidence interval: 0.92-0.99, p=0.02) was an independent predictor of MACE. Contrast volume (170.71+/-47.17ml vs. 136.46+/ 55.56ml, p=0.002) and radiation dose (1.44+/-1.65Gy vs. 0.96+/-0.46Gy, p=0.02) were significantly higher in the FKBT group than in the non-FKBT group. CONCLUSIONS: Single-stent implantation without FKBT may be a sufficient treatment strategy for bifurcation ISR lesions. PMID- 27692567 TI - Prognostic impact of homocysteine levels and homocysteine thiolactonase activity on long-term clinical outcomes in patients undergoing percutaneous coronary intervention. AB - BACKGROUND: Numerous studies have reported the relationship between elevated homocysteine (Hcy) levels and the risk of coronary artery disease. However, there is insufficient information about the effects of Hcy levels on long-term clinical outcomes in patients with coronary artery disease undergoing percutaneous coronary intervention (PCI). METHODS: In the Juntendo-registry cohort from 2003 to 2004, pre-procedural Hcy levels and Hcy thiolactonase activity (HTlase) were measured in 315 consecutive all-comer patients who underwent PCI for stable coronary artery disease or acute coronary syndrome (ACS). Receiver-operating characteristic (ROC) curves were created to assess the optimal cut-off values of Hcy and HTlase. Multivariable Cox proportional hazard regression analysis was used to identify the predictors of clinical outcome. The primary endpoint was all cause mortality. RESULTS: The patients' mean age was 66+/-9 years, and 82.5% were males. The median follow-up period was 10.5 years, and overall mortality was 24.5% (73 deaths). On ROC analysis, the optimal cut-off values of Hcy and HTlase were 13.5MUmol/L and 230IU/L, respectively. Kaplan-Meier survival analysis showed associations of both higher Hcy levels and lower HTlase activity with worse prognosis (both log-rank p<0.001). On multivariate Cox proportional hazard regression analysis, higher Hcy was strongly associated with the primary outcome, and the adjusted hazard ratio was 3.3 (95% confidence interval, 1.8-5.6; p<0.001). CONCLUSIONS: Pre-procedural high Hcy levels and low HTlase activity were associated with worse long-term mortality in Japanese patients undergoing PCI. Moreover, Hcy levels are strongly predictive for mortality, independent of traditional risk factors. This may have implications for risk stratification and the therapeutic approach in this PCI era. PMID- 27692568 TI - Effect of over-2-year dual antiplatelet therapy on the rate of major adverse cardiac and cerebral events for everolimus-eluting stent implantation: The landmark analysis from Tokyo-MD PCI registry. AB - BACKGROUND: Long-term dual antiplatelet therapy (DAPT) for patients treated with coronary stents has been reported to be effective. However the effectiveness of long-term DAPT for everolimus-eluting stent (EES) implanted patients has been controversial. We assessed the major adverse cardiac and cerebral events (MACCE: a composite of death, myocardial infarction, or cerebral arterial disease) in patients free from MACCE during the first 2 years after EES implantation. METHODS AND RESULTS: A total of 1918 patients who underwent successful percutaneous coronary intervention (PCI) with EES at 22 centers in Japan in 2010-2011 were enrolled, and 742 patients were free from MACCE for 2 years. We divided these MACCE-free patients into two groups: those who received DAPT for >2 years (Over-2 Year DAPT: n=591), and those who received DAPT for <=2 years (Under-2-Year DAPT: n=151). We performed the landmark analysis that began at 2 years and evaluated at 3 years after PCI about the occurrence of MACCE, major bleeding, stent thrombosis, and restenosis between these groups, both with and without baseline adjustment by propensity score matching (n=145 in both groups). RESULTS: Fifty MACCE cases were reported (Over-2-Year DAPT, 38; Under-2-Year DAPT, 12), with no significant differences between the 2 groups (log-rank test, p=0.19). Even after baseline adjustment, there were no differences in MACCE occurrence (Over-2-Year DAPT, 8; Under-2-Year DAPT, 11, p=0.19); 15 cases of major bleeding, 5 of restenosis, and 2 of stent thrombosis were observed after 2-years' follow-up, with no statistical differences between the groups, although the event numbers were too low for comparison. CONCLUSION: Continuing DAPT for >2 years did not prevent MACCE in patients free from MACCE during initial 2 years after EES implantation. Few events of major bleeding, stent thrombosis, and restenosis were observed, with no statistical differences. PMID- 27692569 TI - Anatomic features of independent right posterior portal vein variants: Implications for left hepatic trisectionectomy. AB - BACKGROUND: No authors have reported on the anatomic features of the independent right posterior portal vein variant and its relevance to left hepatic trisectionectomy. The purpose of this study was to review vasculobiliary systems according to portal vein anatomy, to clarify the anatomic features of the right posterior portal vein variant, and to discuss its operative implications for left hepatic trisectionectomy. METHODS: In a radiologic study, the 3-dimensional anatomy of the portal vein, hepatic artery, and bile duct were studied in 200 patients who underwent computed tomography. In a surgical study, medical records were retrospectively reviewed for 463 patients who underwent hepatectomy for perihilar cholangiocarcinoma. RESULTS: In the radiologic study, an independent right posterior portal vein variant was observed in 19 patients. The following observations were made in association with the portal vein variant: (1) a supraportal or combined type right posterior hepatic artery was never found; (2) an infraportal right posterior bile duct was observed at a significantly greater frequency than in patients with normal portal vein anatomy; and (3) the volume of the right posterior sector was significantly larger than in normal portal vein anatomy (37.4 +/- 6.1% vs 27.3 +/- 5.1%, P < .001). In the surgical study, the independent right posterior portal vein variant was observed in 41 (8.9%) patients. Of the 135 patients who underwent left hepatic trisectionectomy, 28 (20.7%) had this portal vein variant. CONCLUSION: Independent right posterior portal vein variants exhibit anatomic features that are advantageous for performing left hepatic trisectionectomy.

PMID- 27692571 TI - The added value of a surveillance human biomonitoring program: The case of FLEHS in Flanders (Belgium). AB - Since 2002, the Flemish Government decided to carry out the Flemish Environment and Health Survey (FLEHS), an extended human biomonitoring (HBM) program, which is integrated in the environmental health policy. Through the FLEHS studies, a vast amount of data such as biomarkers of exposure and effect, exposure-effect associations, time trends and geographical differences, became available to the Flemish policy makers. In order to facilitate the policy interpretation, a phased action-plan was developed collaboratively by FLEHS researchers and policy makers. In this article we look back on more than 15 years of investments of the Flemish government in HBM and reflect on how this large scaled and challenging HBM initiative contributed to shaping the environmental health policy in Flanders. We used the FLEHS I (2002-2006) and II (2007-2011) results on persistent organic pollutants (POPs) and the resulting policy actions as an example to illustrate the added value of HBM for policy making. Policy measures for POPs, including source-related regulation (e.g. further optimization and tightening of existing Flemish legislation on open fires), investment in monitoring networks and communication and awareness campaigns, are presented and the added value for environmental health policy is discussed. We also reflect on how HBM can support science and innovation in the environmental monitoring context. Finally, we describe what society can gain from HBM in terms of opportunities for (1) feeding the political and societal debate, (2) stimulating community involvement and (3) empowering participants and citizens. All together, the gained insights and phased action plan showed that next to compliance with high scientific standards, results of the Flemish human biomonitoring campaign could be translated in targeted policy actions even for chemicals that have since long been regulated. PMID- 27692572 TI - Characterization of exposure in epidemiological studies on air pollution from biodegradable wastes: Misclassification and comparison of exposure assessment strategies. AB - The assignment of exposure is one of the main challenges faced by environmental epidemiologists. However, misclassification of exposures has not been explored in population epidemiological studies on air pollution from biodegradable wastes. The objective of this study was to investigate the use of different approaches for assessing exposure to air pollution from biodegradable wastes by analyzing (1) the misclassification of exposure that is committed by using these surrogates, (2) the existence of differential misclassification (3) the effects that misclassification may have on health effect estimates and the interpretation of epidemiological results, and (4) the ability of the exposure measures to predict health outcomes using 10-fold cross validation. Four different exposure assessment approaches were studied: ammonia concentrations at the residence (Metric I), distance to the closest source (Metric II), number of sources within certain distances from the residence (Metric IIIa,b) and location in a specific region (Metric IV). Exposure-response models based on Metric I provided the highest predictive ability (72.3%) and goodness-of-fit, followed by IV, III and II. When compared to Metric I, Metric IV yielded the best results for exposure misclassification analysis and interpretation of health effect estimates, followed by Metric IIIb, IIIa and II. The study showed that modelled NH3 concentrations provide more accurate estimations of true exposure than distances based surrogates, and that distance-based surrogates (especially those based on distance to the closest point source) are imprecise methods to identify exposed populations, although they may be useful for initial studies. PMID- 27692573 TI - New specific and sensitive biomonitoring methods for chemicals of emerging health relevance. AB - In this publication the challenges to cope for the aim to obtain innovative biomonitoring methods in our laboratory are visualized for di(2 propylheptyl)phthalate, 2-mercaptobenzothiazole, 3,5-di-tert-butyl-4 hydroxytoluene, 4-nonylphenol, 4-tert-octylphenol, 3-(4 methylbenzylidene)camphor, 4,4'-methylene diphenyl diisocyanate, and Hexabromocyclododecane. For these substances new specific markers were explored based on animal or human kinetic data with urine being the preferred matrix compared to blood. The determination of these markers was complex in all cases, because the sample preparation as well as the detection by high performance liquid chromatography, capillary gas chromatography coupled to tandem mass spectrometers or high resolution mass spectrometry should enable the lowest possible detection limit by use of minimal biological sample volumes. To get a first hint of a possible background level, the analytical methods were applied to urine samples of about 40 persons for each chemical. For Di(2 propylheptyl)phthalate and 2-Mercaptobenzothiazole first results are presented from population biomonitoring. PMID- 27692575 TI - The impact of nutrition education on nutrition knowledge and adherence to the Mediterranean Diet in adolescent competitive swimmers. AB - OBJECTIVES: Nutrition education of adolescent competitive swimmers is under studied although their diet and nutrition knowledge are generally poor. This study aimed to assess the impact of nutrition education on nutrition knowledge and adherence to the Mediterranean Diet (MD) and explore the effect of parental education on the swimmers' MD adherence. DESIGN: A pre-post measurement interventional study was carried out. METHODS: A half-day nutrition education session was delivered for the swimmers and a separate session for their parents. At baseline and 6-weeks post-workshop, a short nutrition knowledge assessment of food sources of nutrients and the MD composition as well as adherence to the MD using the KIDMED Index were undertaken. The swimmers' parents also completed the KIDMED Index to evaluate the swimmers' diet. RESULTS: Thirty-four competitive swimmers (age: 15.2+/-1.5 yr, 23 males) and 22 of their parents participated in the study. There was an improvement in MD adherence with 47% having good adherence post-intervention vs 21% at baseline (p<0.01) and an increase in the KIDMED Index score (median [interquartile range]: 5.0 [4.0-7.0] vs 7.0 [7.0-9.0]; p<0.01)). There was also an increase in the swimmers' nutrition knowledge assessment score (median [IQR]: 7.0 [5.0-8.0] vs 7.0 [6.0-8.0], p<0.05)), and a trend for a lower score post-intervention in swimmers whose parents did not participate compared to those whose parents participated (6.0 [6.0-7.8] vs 7.0 [7.0-8.0], p=0.063). CONCLUSIONS: The intervention improved adherence to the MD and increased nutrition knowledge. The findings support parental participation in nutrition education. PMID- 27692574 TI - [Epigenetics and obesity]. AB - Current evidence supports the notion that exposure to various environmental conditions in early life may induce permanent changes in the epigenome that persist throughout the life-course. This article focuses on early changes associated with obesity in adult life. A review is presented on the factors that induce changes in whole genome (DNA) methylation in early life that are associated with adult onset obesity and related disorders. In contrast, reversal of epigenetic changes associated with weight loss in obese subjects has not been demonstrated. This contrasts with well-established associations found between obesity related DNA methylation patterns at birth and adult onset obesity and diabetes. Epigenetic markers may serve to screen indivuals at risk for obesity and assess the effects of interventions in early life that may delay or prevent obesity in early life. This might contribute to lower the obesity-related burden of death and disability at the population level. The available evidence indicates that epigenetic marks are in fact modifiable, based on modifications in the intrauterine environment and changes in food intake, physical activity and dietary patterns patterns during pregnancy and early years of adult life. This offers the opportunity to intervene before conception, during pregnancy, infancy, childhood, and also in later life. There must be documentation on the best preventive actions in terms of diet and physical activity that will modify or revert the adverse epigenetic markers, thus preventing obesity and diabetes in suceptible individuals and populations. PMID- 27692576 TI - Assessing muscle strength for the purpose of classification in Paralympic sport: A review and recommendations. AB - OBJECTIVES: Classification in Paralympic Sport aims to minimize the impact of 10 eligible types of impairment on the outcome of competition. Methods for assessing the extent to which a given body structure or function has been impaired are required, but are challenging because it is not possible to directly measure an absence or loss. Rather, impairment must be inferred by measurement of extant body structures or functions. METHODS: This manuscript reviews the literature concerning the assessment of strength with the aim of identifying and describing the most appropriate method for inferring strength impairment in para-athletes. RESULTS: It is posited that the most appropriate voluntary strength assessment method for inferring strength loss in para-athletes will be multi-joint, isometric tests performed at joint angles that facilitate maximum force production. CONCLUSIONS: Evidence suggests such methods will permit development of tests that are specific to a variety of para-sports and which are reliable, ratio-scaled, and resistant to training. Future research should: develop sport specific tests which are suitable for assessment of athletes with strength impairments of variable severity and distribution; and scientifically evaluate the extent to which such tests permit strength impairment to be validly inferred, including specific evaluation of the extent to which such measures respond to athletic training. PMID- 27692577 TI - Surface properties of polyetheretherketone after different laboratory and chairside polishing protocols. AB - STATEMENT OF PROBLEM: Polyetheretherketone (PEEK) can be used as a framework material for fixed dental prostheses. However, information about laboratory and chairside polishing methods is still scarce. PURPOSE: The purpose of this in vitro study was to determine the effects of laboratory and chairside polishing methods on the surface roughness (SR) and surface free energy (SFE) of PEEK, an autopolymerizing poly(methyl methacrylate), and a veneering composite resin. MATERIAL AND METHODS: For each of the 3 materials, 80 specimens were prepared (N=240) and divided into 7 polishing groups and 1 control group (n=10). The 7 groups were split into 4 laboratory protocols: polishing paste (Abraso), a second polishing paste (Opal L), silicone polisher (Ceragum), and diamond grinder (Diagen-Turbo grinder). The other 3 groups were chairside protocols: rainbow technique (Super-Snap kit), polishing paste (Prisma gloss), and a polishing system (Enhance finishing). Machine polishing with SiC P4000 served as the control treatment. The protocols' average SRs and SFEs were measured, and their surface topographies were evaluated with scanning electron microscopy (SEM). The logarithmically transformed data were analyzed using covariance analysis, 2-way and 1-way ANOVA, and partial correlation (alpha=.05). RESULTS: The polishing protocol exerted the highest influence on SR and SFE values (P<.001; SR: partial eta squared etaP2=.970; SFE: etaP2=.450), followed by material group (P<.001, SR: etaP2=.319; SFE: etaP2=.429). The interaction effect of the binary combinations of the 2 independent parameters (polishing protocol and material group) was also significant (P<.001, SR: etaP2=.681; SFE: etaP2=.365). CONCLUSIONS: Chairside methods presented lower SR values than laboratory methods, and specimens polished using the 2-body mode showed higher SR than did specimens polished using the 3 body mode. PMID- 27692578 TI - Patient-centered and clinical outcomes of mandibular overdentures retained with the locator system: A prospective observational study. AB - STATEMENT OF PROBLEM: Whether clinical or demographic variables affect the perception of treatment in terms of quality of life and satisfaction is unknown. PURPOSE: The purpose of this prospective study was to make an evidence-based assessment of the treatment outcomes (patient- and clinically based) of locator retained mandibular overdentures. MATERIAL AND METHODS: This prospective observational study assessed patients with edentulism who had worn mandibular overdentures supported by 2 implants and retained by the locator system for at least 1 year of functional life (N=80). Medical histories were reviewed, and patients underwent oral examinations. Prosthetic clinical outcomes and patient well-being were registered using the Oral Health Impact Profile 20 (OHIP-20) and Oral Satisfaction Scale (OSS). RESULTS: Patient well-being scored an overall OHIP 20 score of 19.0 +/-14.0 of 80 (the higher the score, the greater the impact and the worse the oral health-related quality of life); overall oral satisfaction was 8.3 +/-1.7 of 10. Women suffered greater social impact (0.8 +/-1.0) and disability (0.4 +/-0.8) than men (0.4 +/-0.7 versus 0.2 +/-0.4, respectively). Impact on well-being was inversely proportional to both patient age and the age of the prosthesis (r=-0.25; P<.01). Implants had been placed on average 73.6 +/ 39.2 months previously, showing a survival rate of 82.5%. Most of the overdentures had been functioning for over 60 months. Relining (46.3%), readjustments (82.5%), and changes of nylon retention (1.5 +/-1.8 per patient over 60 months of use) devices negatively influenced well-being. CONCLUSIONS: Mandibular overdentures produced good results with regard to quality of life and oral satisfaction, but attention should be paid to factors affecting clinical outcomes and patient well-being. PMID- 27692579 TI - In vivo study of the effectiveness of quantitative percussion diagnostics as an indicator of the level of structural pathology of teeth after restoration. AB - STATEMENT OF PROBLEM: Conventional diagnostic aids based upon imagery and patient symptoms do not indicate whether restorative treatments have eliminated structural pathology. PURPOSE: The purpose of this clinical study was to evaluate quantitative percussion diagnostics (QPD), a mechanics-based methodology that tests the structural integrity of teeth noninvasively. The study hypothesis was that QPD would provide knowledge of the structural instability of teeth after restorative work. MATERIAL AND METHODS: Eight participants with 60 sites needing restoration were enrolled in an IRB-approved clinical study. Each participant was examined comprehensively, including QPD testing. Each site was disassembled and microscopically video documented, and the results were recorded on a defect assessment sheet. A predictive model was developed for the pathology rating based on normalized fit error (NFE) values using data from the before treatment phase of the study published previously. Each restored site was then tested using QPD. The mean change in NFE values after restoration was evaluated by the pathology rating before treatment. The model was then used to predictively classify the rating after restoration based on the NFE values after treatment. The diagnostic potential of the rating was explored as a marker for risk of pathology after restoration. RESULTS: After restoration, 51 of the 60 sites fell below an NFE of 0.04, representing a greatly stabilized tooth site sample group. Several sites remained in the high-risk category and some increased in pathologic micromovement. Two models were used to determine severity with indicative cutoff points to group sites with similar values. CONCLUSIONS: The data support the hypothesis that QPD can indicate a revised level of structural instability of teeth after restoration. PMID- 27692581 TI - Precision prosthodontics. PMID- 27692580 TI - Implant-supported maxillary denture retained by a telescopic abutment system: A clinical report. AB - An implant-supported fixed dental prosthesis is one of the treatment options for an individual with a completely edentulous maxilla. However, a screw-retained or cemented prosthesis can make oral hygiene difficult, especially for patients with a history of periodontal disease or disabilities. Compared with maxillary fixed dental prostheses, implant-supported overdentures offer similar retention and function and facilitate esthetics, phonetics, and hygiene. This report describes the prosthetic rehabilitation of a patient with an edentulous maxilla and a severe maxillomandibular discrepancy that involved the use of a novel prefabricated telescopic system to retain an implant-supported removable dental prosthesis. PMID- 27692582 TI - Effect of silane contamination on dentin bond strength. AB - STATEMENT OF PROBLEM: Intraoral repair of porcelain or other silica-based ceramics typically requires the use of silane in the repair protocol. Some porcelain intraoral repairs also involve bonding to exposed or involved tooth tissues including dentin. A study is needed to evaluate whether the cross contamination of dentin with silane affects bond strength to this tissue. PURPOSE: The purpose of this in vitro study was to investigate the effect of silane cross-contamination on dentin bond strength. MATERIAL AND METHODS: Flat surfaces of human dentin specimens were created, followed by wet polishing with 320-grit silicon carbide paper. The dentin specimens were divided into 4 groups: group SE (All-Bond Universal Adhesive used in self-etching mode); group SiSE (silane applied to dentin followed by All-Bond Universal Adhesive used in self etching mode); group ER (All-Bond Universal Adhesive used in total-etch (etch-and rinse) mode); and group ERSi (Etch and rinse and silane applied to dentin followed by All-Bond Universal Adhesive). The dentin specimens were treated with a universal adhesive (All-Bond Universal) and bonded with a composite resin, using an Ultradent jig mold. Shear bond strength (n=10) was measured after 24 hours of water storage at 37 degrees C. After the shear bond strength test, the dentin sides of fractured specimens in each group were examined with a stereomicroscope at *15 magnification to determine failure modes. Data were statistically analyzed by 2-way and a 1-way ANOVA followed by post hoc Tukey honest significant difference test (alpha=.05). Scanning electron microscopy examination was used to evaluate the dentin surface morphology before and after bonding. RESULTS: The shear bond strength of composite resin to dentin was not affected adversely when the dentin was contaminated with silane prior to using All-Bond Universal in the self-etch or total- etch (phosphoric acid) mode. SE, 30.3 +/-3.8 MPa; SiSE, 32.9 +/-3.9 MPa; ER, 34.9 +/-3.1 MPa; ERSi: 35.2 +/-4.9 MPa (P>.05) CONCLUSIONS: Under the conditions of this study, cross-contamination of dentin with silane before the use of All-Bond Universal in the self-etch or total-etch with phosphoric acid mode did not adversely affect composite resin bond strength to dentin. PMID- 27692583 TI - Using modified polyetheretherketone (PEEK) as an alternative material for endocrown restorations: A short-term clinical report. AB - A modified polyetheretherketone (PEEK) framework material veneered with indirect light-polymerized composite resin was used as an alternative material for the fabrication of an endocrown restoration for an extensively damaged molar. The elastic modulus of the polyetheretherketone framework (4 GPa) veneered with indirect composite resin could dampen the occlusal forces protecting tooth structures better than ceramic materials. This is important in the restoration of extensively damaged molars with weak roots. Long-term clinical evidence is required before recommending the application as a substitute material. PMID- 27692584 TI - Internal fit of single crowns produced by CAD-CAM and lost-wax metal casting technique assessed by the triple-scan protocol. AB - STATEMENT OF PROBLEM: Whether single crowns produced by computer-aided design and computer-aided manufacturing (CAD-CAM) have an internal fit comparable to crowns made by lost-wax metal casting technique is unknown. PURPOSE: The purpose of this in vitro study was to compare the internal fit of single crowns produced with the lost-wax and metal casting technique with that of single crowns produced with the CAD-CAM technique. MATERIAL AND METHODS: The internal fit of 5 groups of single crowns produced with the CAD-CAM technique was compared with that of single crowns produced in cobalt-chromium with the conventional lost-wax and metal casting technique. Comparison was performed using the triple-scan protocol; scans of the master model, the crown on the master model, and the intaglio of the crown were superimposed and analyzed with computer software. The 5 groups were milled presintered zirconia, milled hot isostatic pressed zirconia, milled lithium disilicate, milled cobalt-chromium, and laser-sintered cobalt-chromium. RESULTS: The cement space in both the mesiodistal and buccopalatal directions was statistically smaller (P<.05) for crowns made by the conventional lost-wax and metal casting technique compared with that of crowns produced by the CAD-CAM technique. CONCLUSIONS: Single crowns made using the conventional lost-wax and metal casting technique have better internal fit than crowns produced using the CAD-CAM technique. PMID- 27692585 TI - A new 3D center of mass control approach for FES-assisted standing: First experimental evaluation with a humanoid robot. AB - This paper proposes a new control framework to restore the coordination between upper (functional) and lower (paralyzed) limbs in the context of functional electrical stimulation in completely paraplegic individuals. A kinematic decoupling between the lower and upper limbs controls the 3D whole-body center of mass location and the relative foot positions by acting only on the lower-limb joints. The upper limbs are free to move under voluntary control, and are seen as a perturbation for the lower limbs. An experimental validation of this paradigm using a humanoid robot demonstrates the real-time applicability and robustness of the method. Different scenarios mimicking the motion of a healthy subject are investigated. The proposed method can maintain bipedal balance and track the desired center of mass trajectories under movement disturbances of the upper limbs with an error inferior to 0.01 m under any conditions. PMID- 27692586 TI - Australian general practitioners' views regarding providing nutrition care: results of a national survey. AB - BACKGROUND: The prevalence of chronic disease is considerable, and dietary behaviours influence the progression of many chronic diseases. Practice guidelines recommend that general practitioners (GPs) promote healthy dietary behaviours in relevant consultations with patients in order to improve health outcomes at a population level. OBJECTIVE: To describe GPs' perceived interest, confidence and barriers to support patients to have a healthy diet. METHOD: A 24 item online and written survey was distributed in a national weekly newsletter to GPs in Australia. Results were descriptively analysed and investigated for associations with GPs' demographic characteristics. RESULTS: A total of 322 GPs responded to the survey. Nearly all (n = 295, 91.6%) were interested in supporting patients to eat well, and most (n = 231, 71.7%) reported moderately high confidence for providing nutrition care with clear public health messages for conditions, such as cardiovascular disease. Many GPs (n = 170, 52.8%) cited lack of time as the biggest barrier to providing nutrition care, and the overwhelming majority (n = 289, 89.8%) were interested in receiving additional education and training to enhance their nutrition knowledge and skills. DISCUSSION: Many GPs are interested in nutrition and would benefit from educational programmes that improve their competence to provide nutrition care. Professional development opportunities should focus on the identification of nutritional risk and the promotion of healthy dietary behaviours within the time constraints of a standard consultation. PMID- 27692587 TI - Arthroscopic anatomical reconstruction of the lateral ankle ligaments: A technical simplification. AB - Anatomical reconstruction of the lateral ankle ligaments has become a pivotal component of the treatment strategy for chronic ankle instability. The recently described arthroscopic version of this procedure is indispensable to ensure that concomitant lesions are appropriately managed, yet remains technically demanding. Here, we describe a simplified variant involving percutaneous creation of the calcaneal tunnel for the distal attachment of the calcaneo-fibular ligament. The rationale for this technical stratagem was provided by a preliminary cadaver study that demonstrated a correlation between the lateral malleolus and the distal footprint of the calcaneo-fibular ligament. The main objectives are simplification of the operative technique and decreased injury to tissues whose function is crucial to the recovery of proprioception.

AB - RATIONALE AND OBJECTIVES: This study aimed to assess the performance of a text classification machine-learning model in predicting highly cited articles within the recent radiological literature and to identify the model's most influential article features. MATERIALS AND METHODS: We downloaded from PubMed the title, abstract, and medical subject heading terms for 10,065 articles published in 25 general radiology journals in 2012 and 2013. Three machine-learning models were applied to predict the top 10% of included articles in terms of the number of citations to the article in 2014 (reflecting the 2-year time window in conventional impact factor calculations). The model having the highest area under the curve was selected to derive a list of article features (words) predicting high citation volume, which was iteratively reduced to identify the smallest possible core feature list maintaining predictive power. Overall themes were qualitatively assigned to the core features. RESULTS: The regularized logistic regression (Bayesian binary regression) model had highest performance, achieving an area under the curve of 0.814 in predicting articles in the top 10% of citation volume. We reduced the initial 14,083 features to 210 features that maintain predictivity. These features corresponded with topics relating to various imaging techniques (eg, diffusion-weighted magnetic resonance imaging, hyperpolarized magnetic resonance imaging, dual-energy computed tomography, computed tomography reconstruction algorithms, tomosynthesis, elastography, and computer-aided diagnosis), particular pathologies (prostate cancer; thyroid nodules; hepatic adenoma, hepatocellular carcinoma, non-alcoholic fatty liver disease), and other topics (radiation dose, electroporation, education, general oncology, gadolinium, statistics). CONCLUSIONS: Machine learning can be successfully applied to create specific feature-based models for predicting articles likely to achieve high influence within the radiological literature. PMID- 27692589 TI - Associations Between Academic Rank and Advanced Bibliometric Indices Among United States Academic Radiologists. AB - RATIONALE AND OBJECTIVES: This study aimed to evaluate associations between traditional and advanced bibliometric indices with academic rank for radiologists in the United States. METHODS: Faculty web pages were searched to classify 538 members of the Association of University Radiologists as assistant (n = 212), associate (n = 128), or full (n = 198) professors. Radiologists' publication and citation records were extracted from Scopus to compute the following indices: publication count, citation count, h-index, i-10 index, hc-index, m-quotient, e index, and g-index. Analysis of variance, multivariable logistic regression, and receiver operating characteristic curve analysis were performed. RESULTS: All indices were significantly different among the three groups (P <=.001), progressively increasing with increasing rank (eg, mean publication count of 17, 41, and 128 among assistant, associate, and full professors, respectively; mean citation count of 205, 687, and 3622, respectively; mean h-index of 5, 11, and 27, respectively). At multivariable analysis, the h-index (reflecting publications and citations) was a strong significant independent positive predictor of associate (beta=+0.32, P <.001) or full professor (beta=+0.26, P <.001) status, whereas the m-quotient (adjusted h-index that is greater for more rapid publication) was a strong significant independent negative predictor of associate (beta=-1.87, P = .009) or full professor (beta =-4.97, P <.001) status. The models exhibited moderate goodness-of-fit (r2 = 0.534-0.655; P <.001). The model for predicting at least associate professor achieved area under the curve 0.876 (sensitivity 74.6%, specificity 88.8%). The model for predicting full professor achieved area under the curve 0.925 (sensitivity 85.5%, specificity 86.1%). CONCLUSION: When controlling for the h-index, more rapid publication, as indicated by the m-quotient, was negatively associated with radiologists' academic rank, indicating the additional influence of career duration in promotions decisions. PMID- 27692590 TI - Regional and network relationship in the intracranial EEG second spectrum. AB - OBJECTIVE: We examined low-frequency amplitude modulations of band power time series, i.e. the second spectrum, of the intracranial EEG (icEEG) for evidence of support for spatial relationships between different parts of the brain and within the default mode network (DMN). METHODS: We estimated magnitude-squared coherence (MSC) of the running power in the delta, theta, alpha, beta, and gamma frequency bands for one-hour background icEEG epochs recorded from 9 patients. We isolated two test areas within the DMN and one control area outside it. We tested if the relationship between DMN areas was stronger than the relationship between each of these areas and the control location, and between all intrahemispheric contact pairs with similar intercontact distance. RESULTS: We observed very low values of second spectrum relationship between different parts of the brain, except at very short distances. These relationships are strongest in the delta band and decrease with increasing frequency, with gamma band relationships being the weakest. Our DMN-specific analysis showed no enhanced connectivity in the second spectrum in DMN locations in any frequency band. CONCLUSIONS: Though we observed significantly nonzero relationships in lower frequency bands, second spectrum relationships are consistently very low across the entire brain in every frequency band. SIGNIFICANCE: This study suggests a lack of support for the DMN in the icEEG second spectrum.

PMID- 27692592 TI - Meta-Analysis of Association Between Mediastinal Radiotherapy and Long-Term Heart Failure. AB - This investigation sought to identify and quantify any increased risk of long term heart failure (HF) after thoracic radiotherapy (RT) for cancer and identify any population covariates that corresponded with increased risk. Electronic databases were systematically searched for studies reporting relative risk, odds ratio, and hazard ratio (HR) for symptomatic HF more than 5 years after RT administration. Clinical characteristics, study design, univariable effect sizes, and associated 95% CIs were extracted. Univariable effect size was pooled and computed in a meta-analysis using random-effects model weighted by inverse variance. Six studies (45,669 patients) with weighted median follow-up duration of 13.9 years were included, each data-linkage study that reported HRs for HF. Pooled HR for long-term HF was significant (HR 1.83 [1.09 to 3.08], p = 0.022), with significant between-study heterogeneity (Q 43.38, df = 5, p <0.001, I2 88.47%). Statistical significance was lost when excluding studies of malignancies other than breast cancer or hematological malignancies and excluding studies with Newcastle-Ottawa scores <8, but the direction of effect and magnitude remained approximately the same. Subgroup and meta-regression analyses demonstrated that study differences in age at time of RT administration and duration of follow-up explained approximately 80% of observed heterogeneity. Earlier publication date was associated with increased HF risk. Other variables, including female proportion, proportion of adjuvant chemotherapy use, and sample size did not significantly impact the conclusions. In conclusion, RT approximately doubled the long-term risk of HF. This finding was associated with younger age at time of RT and longer follow-up duration, which explained approximately 80% of interstudy heterogeneity. PMID- 27692593 TI - Long-Term Follow-Up of Patients With Previous Coronary Artery Bypass Grafting Undergoing Percutaneous Coronary Intervention for Chronic Total Occlusion. AB - Successful revascularization of chronic total occlusions (CTOs) has been associated with clinical benefit. Data on outcomes in patients with previous coronary artery bypass grafting (CABG) undergoing percutaneous coronary intervention (PCI) for CTO, however, are scarce. A total of 2,002 consecutive patients undergoing PCI for CTO from January 2005 to December 2013 were divided into patients with and without previous CABG, and outcomes were retrospectively assessed. The primary outcome measure was all-cause mortality. Median follow-up was 2.6 years (interquartile range 1.1 to 3.1). A total of 292 patients (15%) had previous CABG; they were older and had a greater prevalence of comorbidities. Procedural success was achieved in 75% and 84% of patients in the previous CABG and the non-CABG groups (p <0.001), respectively. All-cause mortality was 16% and 11% in the previous CABG and the non-CABG groups (p = 0.002), and differences were mitigated after adjustment for baseline characteristics (adjusted hazard ratio [HR] 1.22, 95% confidence interval [CI] 0.86 to 1.74, p = 0.27). All-cause death was significantly reduced in patients with procedural success, both in the previous CABG (11% vs 32%, adjusted HR 0.43, 95% CI 0.24 to 0.77, p = 0.005) and the non-CABG groups (10% vs 20%, adjusted HR 0.63, 95% CI 0.45 to 0.86, p = 0.004), with similar mortality benefits associated with successful revascularization in both groups (interaction p = 0.24). In conclusion, the relative survival benefit of successful recanalization of CTO is independent of previous CABG. However, owing to a greater baseline risk, the absolute survival benefit of successful CTO procedures is more pronounced in patients with previous CABG than in non-CABG patients. PMID- 27692594 TI - Meta-Analysis of Randomized Trials on the Efficacy and Safety of Angiotensin Converting Enzyme Inhibitors in Patients >=65 Years of Age. AB - The comparative efficacy and safety of angiotensin-converting enzyme inhibitors (ACEIs) with other agents in patients >=65 years of age with cardiovascular diseases or at-risk are unknown. Electronic databases were systematically searched to identify all randomized controlled trials that compared ACEIs with control (placebo or active) and reported long-term cardiovascular outcomes. We required the mean age of patients in the studies to be >=65 years. Random-effects model was used to pool study results. Sixteen trials with 104,321 patients and a mean follow-up of 2.9 years were included. Compared with placebo, ACEIs significantly reduced all outcomes except stroke. Compared with active controls, ACEIs had similar effect on all-cause mortality (relative risk [RR] 0.99, 95% confidence interval [CI] 0.95 to 1.03), cardiovascular mortality (RR 0.99, 95% CI 0.93 to 1.04), heart failure (RR 0.97, 95% CI 0.91 to 1.03), myocardial infarction (RR 0.94, 95% CI 0.88 to 1.00), and stroke (RR 1.07, 95% CI 0.99 to 1.15). ACEIs were associated with an increased risk of angioedema (RR 2.79, 95% CI 1.05 to 7.42), whereas risk for hypotension and renal insufficiency was similar compared with active controls. Meta-regression analysis showed that the effect of ACEIs on outcomes remained consistent with age increasing >=65 years. Sensitivity analysis excluding trials comparing ACEIs with angiotensin receptor blockers and heart failure trials yielded similar results, except for reduction in myocardial infarction. In conclusion, the efficacy of ACEIs was similar to active controls for mortality outcomes. Compared with placebo, there was evidence for reduction in cardiovascular outcomes; however, ACEIs failed to prevent stroke and increased the risk of angioedema, hypotension, and renal failure. PMID- 27692596 TI - Stop Blowing Smoke on Cigarettes as a Cause for Periodontitis. PMID- 27692595 TI - Local Versus General Anesthesia in Transcatheter Aortic Valve Replacement. AB - Transcatheter aortic valve replacement (TAVR) is conventionally performed under general anesthesia (GA) allowing intraoperative transoesophageal echocardiogram imaging. We present our experience in patients having the procedure under local anesthesia (LA), who were subsequently transferred to a low dependency unit postprocedure, to assess safety and length of hospital stay. We retrospectively assessed all the transfemoral TAVR procedures conducted at our center from January 03, 2011. Of 216 patients, 145 had the procedure under GA and 71 under LA. Both groups were similar with respect to age, co-morbidities, Euro Score, and the severity of the aortic stenosis. The procedure time was significantly shorter in the LA group measured from time in room to skin closure (108 vs 143 minutes, p <0.001). Skin open to skin closure time were the same in both groups (78 vs 79.4 minutes, p = 0.57). There was no difference in 30 days: aortic regurgitation > mild (2.1% in GA and 2.8% in LA, p = 0.67), need for permanent pacing (3.4% in GA and 1.4% in LA, p = 0.32), and disabling cerebrovascular accidents (1.4% and 1.4%, p = 1.0). The 30-day survival was not significantly different (95.9% in GA and 100% in LA, p = 0.17), whereas the median number of days in hospital was shorter in the LA group (4 in GA and 2 in LA, p <0.001). No emergency conversions to GA were performed in the LA group and only 1 patient needed admission to a high dependency (HD) unit. In conclusion, performing a TAVR under LA is at least as safe as GA. In addition, there is a reduced procedural time and length of hospital stay. LA is a safe and cost-effective alternative to GA and patients can be safely transferred to a low dependency unit.

PMID- 27692597 TI - Usefulness of Serial N-terminal Pro-B-type Natriuretic Peptide Measurements to Predict Cardiac Death in Acute and Chronic Dilated Cardiomyopathy in Children. AB - N-terminal pro-B-type natriuretic peptide (NT-proBNP) is an important predictor of outcome in adults with heart failure. In children with heart failure secondary to dilated cardiomyopathy (DC) markers that reliably predict disease progression and outcome during follow-up are scarce. We investigated whether serial NT-proBNP measurements were predictive for outcome in children with DC. All available NT proBNP measurements in children with DC were analyzed. Linear mixed-effect models and Cox regression were used to analyze the predictive value of NT-proBNP on the end point of cardiac death (death, heart transplantation, or mechanical circulatory support). During 7 years, 115 patients were included. At diagnosis, median NT-proBNP was high and not predictive for outcome. At any time during follow-up, a twofold higher NT-proBNP resulted in a 2.9 times higher risk in the first year (p <0.001) and a 1.8 times higher risk thereafter (p <0.001). Furthermore, at any time, the slope of log10(NT-proBNP) was significantly predictive for the risk of an end point (0 to 30 days hazard ratio [HR] 3.5, >30 days HR 2.9; >1 year HR 6.4). In patients with idiopathic DC (IDC) at 30 days after diagnosis, NT-proBNP >=7,990 pg/ml showed a 1- and 2-year event-free survival of 79% and 71% and >1 year after diagnosis NT-proBNP >=924 pg/ml showed a 2- and 5-year event-free survival of 50% and 40%, whereas below both thresholds event-free survival was 100%. In non-IDC, these thresholds were not predictive for outcome. In conclusion, NT-proBNP at any time during follow-up and its change over time were significantly predictive for the risk of cardiac death in children with DC. In children with IDC >1 year after diagnosis, NT-proBNP >924 pg/ml identified a subgroup with a poor outcome. PMID- 27692599 TI - Reproductive outcome in European and Middle Eastern/North African patients. AB - The aim of this retrospective cohort study was to assess differences in infertility-related baseline characteristics and IVF outcome between European and Middle Eastern/North African (MENA) patients. Of 2703 patients undergoing their first IVF cycle, 2485 were Caucasian of European descent and 218 originated from the MENA region. MENA patients were significantly younger (30.6 versus 34.0 years, P < 0.001), less likely smokers, with higher body mass indexes. Infertility duration was longer in MENA patients (P < 0.001), their male partners were younger (P < 0.001) and smoked more often than European male patients (P = 0.005). Male factor infertility (P = 0.017) and polycystic ovary syndrome (PCOS; P = 0.032) was more prevalent in MENA patients, showed significantly higher basal FSH concentrations (P = 0.012) and significantly fewer oocytes retrieved (RR 0.83, 95% CI 0.74-0.93, P = 0.001). Clinical pregnancy rates were comparable (22.4% [European] versus 22.9% [MENA]). Fewer MENA patients had surplus embryos cryopreserved (OR 0.41, 95% CI 0.22-0.76, P = 0.004). Despite younger age and higher prevalence of PCOS, MENA patients had significantly lower oocyte yields than their European counterparts (P = 0.001). These findings suggest a more rapid decline in ovarian function in women of MENA descent. PMID- 27692600 TI - Maternal serum markers in predicting successful outcome in expectant management of missed miscarriage. AB - The aim of this study was to evaluate the use of biological serum markers, available routinely in most hospital clinical laboratories, in predicting successful outcomes of expectant management in women presenting with a missed miscarriage. This is a single centre observational prospective study over a 16 month period. Among the 490 women who consented to the study protocol, 83 presented with missed miscarriage during the first trimester of pregnancy and opted for expectant management. The mean gestation sac diameter and volume of the gestation sac were recorded during ultrasound examination. Maternal serum samples were obtained in each case and assayed for human chorionic gonadotrophin, progesterone, pregnancy associated plasma protein A (PAPP-A) and high-sensitivity C-reactive protein using commercial assays. When examined individually, maternal age (P = 0.01), progesterone (P = 0.03) and PAPP-A (P = 0.02) were all significantly associated with successful expectant management. Increased maternal age was associated with an increased chance of success with the odds of success increased by around 75% for a 5-year increase in age. Higher values of progesterone and PAPP-A were associated with a reduced chance of successful management. Low maternal serum progesterone concentration was the strongest parameter associated with a successful spontaneous completion of miscarriage. PMID- 27692601 TI - Deficient expression of JMJD1A histone demethylase in patients with round spermatid maturation arrest. AB - JMJD1A (jumonji domain-containing 1A), a known histone H3K9 demethylase, has been identified as a critical epigenetic regulator in male germ cells, activating the sperm chromatin-packaging genes encoding protamines (PRM) and transition proteins (TNP) required for spermatid elongation and condensation. This research investigated the expression pattern of JMJD1A protein in testicular biopsies of 79 infertile men who had undergone testicular sperm extraction. Samples were classified into obstructive azoospermia (OA, n = 26), round spermatid maturation arrest (SMA, n = 29) and Sertoli cell only syndrome (SCOS, n = 24). Experiments including the detection of mRNA and protein expressions of JMJD1A revealed a severe decrease of JMJD1A/JMJD1A in samples with SMA and SCOS compared with samples with OA (P < 0.005, Kruskal-Wallis test). Additional experiments, including incorporation of JMJD1A on the promoter regions of TNP and PRM genes, and the expression of these genes, showed a significant decrease in the SMA and SCOS versus the OA testes (P < 0.005, Kruskal-Wallis test). These findings show the low expression of JMJD1A/JMJD1A, as well as its low incorporation into chromatin in testes with round spermatid maturation arrest, suggesting that a deficient expression of JMJD1A/JMJD1A might be reflecting and/or contributing to round spermatid maturation arrest. PMID- 27692602 TI - Spermatozoa from infertile patients exhibit differences of DNA methylation associated with spermatogenesis-related processes: an array-based analysis. AB - The influence of aberrant sperm DNA methylation on the reproductive capacity of couples has been postulated as a cause of infertility. This study compared the DNA methylation of spermatozoa of 19 fertile donors and 42 infertile patients using the Illumina 450K array. Clustering analysis of methylation data arranged fertile and infertile patients into two groups. Bivariate clustering analysis identified a differential distribution of samples according to the characteristics of seminogram and age, suggesting a possible link between these parameters and specific methylation profiles. The study identified 696 differentially methylated cytosine-guanine dinucleotides (CpG) associated with 501 genes between fertile donors and infertile patients. Ontological enrichment analysis revealed 13 processes related to spermatogenesis. Data filtering identified a set of 17 differentially methylated genes, some of which had functions relating to spermatogenesis. A significant association was identified between RPS6KA2 hypermethylation and advanced age (P = 0.016); APCS hypermethylation and oligozoospermia (P = 0.041); JAM3/NCAPD3 hypermethylation and numerical chromosome sperm anomalies (P = 0.048); and ANK2 hypermethylation and lower pregnancy rate (P = 0.040). This description of a set of differentially methylated genes provides a framework for further investigation into the influence of such variation in male fertility in larger patient cohorts. PMID- 27692603 TI - Spanish Catheter Ablation Registry. 15th Official Report of the Spanish Society of Cardiology Working Group on Electrophysiology and Arrhythmias (2015). AB - INTRODUCTION AND OBJECTIVES: This report presents the findings of the 2015 Spanish Catheter Ablation Registry. METHODS: For data collection, each center was allowed to choose freely between 2 systems: retrospective, requiring the completion of a standardized questionnaire, and prospective, involving reporting to a central database. RESULTS: Data were collected from 82 centers. A total of 12 863 ablation procedures were performed, for a mean of 157+/-119 and a median of 138 procedures per center. The ablation target most frequently treated was cavotricuspid isthmus (n=2992 [23.2%]), followed by atrioventricular nodal reentrant tachycardia (n=2966 [23%]) and atrial fibrillation (n=2640 [20.5%]). There were fewer ablation procedures for atrial tachycardia, idiopathic ventricular tachycardia and accessory pathways, while those for ventricular tachycardia in ischemic cardiomyopathy remained steady. The overall success rate, excluding atrial fibrillation and ventricular tachycardia in cardiomyopathy, was 87.5%, the rate of major complications was 2%, and the mortality rate was 0.08%. CONCLUSIONS: The 2015 registry is the first to show a slight reduction in the number of centers sending in their results and in the total number of ablation procedures performed. The most frequently treated substrate was the cavotricuspid isthmus. There was also a slight decrease in the success rate. The complications and mortality rates remained low.

PMID- 27692605 TI - Anti-Xa bioassays for the laboratory measurement of direct Factor Xa inhibitors in plasma, in selected patients. AB - In the past decade Direct Oral Anti-Coagulants (DOACs), targeting Thrombin or Factor Xa, have enormously facilitated the daily treatment of all relevant patients, including those requiring lifelong therapy. These DOACs have considerable advantages over the use of oral Vitamin K Antagonist (VKA) treatments, in view of having little interferences with food and other medications and also not requiring adjustment for age, gender or weight, with some well-defined exceptions. In this current What's Happening Section we focus on measurements of DiXaIs in plasma using anti-Xa assays, with the objective of providing a tribute to Professor Michel Meyer Samama, who was not only a real leader in this field but, in the past, both authors benefited from his wisdom, as a teacher who dedicated his scientific and professional life (among many other interests in hemostasis, thrombosis and fibrinolysis) to develop and promote methods and strategies for laboratory monitoring of anticoagulants. This review presents the performance characteristics of the Anti-Factor Xa assays (measuring Factor Xa inhibition by drugs), which are available for measuring Direct Factor Xa Inhibitors in plasma, and show good compliance of the results with the reference LC:MS method (which measures the mass of Direct Factor Xa Inhibitors). We also present the preparation and validation of drug specific plasma calibrators and controls which are requested for drug measurements. These assays are convenient and practical laboratory tools which can be used in any laboratory setting, and meet the requirements of regulatory bodies for making smart, quantitative, sensitive, accurate and ease of use assays for measuring DOACs when needed. The manuscript focuses mainly on the following areas of current interest: interference in coagulation assays; anti-Xa laboratory methods; development of calibrators and controls for DiXaIs; method validation and comparison with reference techniques (LC:MS); regulatory requirements and method registrations; newer clinical applications and experience on DiXaIs with Anti-Xa assays, and future perspectives. PMID- 27692606 TI - Blood supply during Japan's 1995 Hanshin-Awaji Earthquake. AB - On January 17, 1995, a magnitude 7.3 earthquake occurred in southern Hyogo Prefecture, a substantially urban area of Japan's main island, Honshu. Now known as the Hanshin-Awaji Earthquake, this disaster damaged or destroyed 639 686 houses and took 6434 lives. Within the disaster area, the Japanese Red Cross (JRC) Hyogo Blood Center had regional responsibilities for collecting, testing, processing, storing, and distributing blood components, including red blood cells (RBCs), fresh frozen plasma (FFP) and platelet concentrates (PLTs). Platelet shakers collapsed, forcing the discard of 103 PLT bags (1125 units) that could not be temperature-controlled or agitated. RBCs and FFP in refrigerated and frozen storage, respectively, remained in temperature control with the help of dry ice imported from non-affected areas. Local blood collection was suspended and replaced by products from other blood centers. Local demand for blood components decreased to 66% of comparable pre-quake demand. Emergent supplies rather than reserved supplies of blood components were markedly increased after the earthquake. Communication infrastructure damage prompted JRC Hyogo Blood Center to send blood delivery vehicles loaded with RBCs and FFP on a circuit of main hospitals in the affected area. Local blood donation and processing resumed 20 days after the quake. In retrospect, a nationally coordinated system of production and distribution demonstrated JRC's ability to meet transfusion demand after the 1995 Hanshin-Awaji Earthquake, and prompted changes in anticipation of subsequent disasters.

PMID- 27692608 TI - Endothelial-to-mesenchymal transition: Cytokine-mediated pathways that determine endothelial fibrosis under inflammatory conditions. AB - During the last decade, the endothelial-to-mesenchymal transition (EndMT) process has attracted considerable attention due to associations with the onset of certain diseases, such as organ fibrosis and cancer. Several studies have assessed the mechanisms and signaling pathways that regulate endothelial fibrosis in the context of human pathologies. A number of inflammatory mediators, including pro-inflammatory cytokines, growth factors, oxidative stress, and toxins, induce the conversion of endothelial cells into mesenchymal fibroblast like cells that promote disease progression. This review is separated into five chapters that critically present current knowledge on EndMT in the context of pathology. First, the main characteristics of EndMT are summarized, with a focus on the endothelial protein pattern changes that modulate the expressions of endothelial/fibrotic markers and extracellular matrix proteins. These expressions could serve as mechanisms for explaining potential EndMT contributions to human pathologies in adults. Second, the main findings supporting a connection between EndMT-mediated endothelial fibrosis and inflammatory conditions are presented. These connections could be linked to the onset and progression of pathological conditions. Third, EndMT inducers are described in detail. This includes considerations on the actions of the first and most well-known EndMT inducer, TGF beta; of the most prominent pro-inflammatory cytokines released during inflammation, such as IL 1-beta and TNF-alpha; and of the NF-kappaB transcription factor, a common player during inflammation-induced EndMT. Furthermore, thorough attention is given to EndMT induction by endotoxins in the context of bacterial infectious diseases. Additionally, the participation of the inflammatory oxidative stress environment in the EndMT induction was also reviewed. Fourth, the pathophysiological findings of inflammation-induced EndMT are presented, and, fifth, special focus is placed on associations with cancer onset and development. Altogether, this review highlights the important role of EndMT-mediated endothelial fibrosis during inflammation in human pathologies. PMID- 27692609 TI - Liver-Resident Memory CD8+ T Cells Form a Front-Line Defense against Malaria Liver-Stage Infection. AB - In recent years, various intervention strategies have reduced malaria morbidity and mortality, but further improvements probably depend upon development of a broadly protective vaccine. To better understand immune requirement for protection, we examined liver-stage immunity after vaccination with irradiated sporozoites, an effective though logistically difficult vaccine. We identified a population of memory CD8+ T cells that expressed the gene signature of tissue resident memory T (Trm) cells and remained permanently within the liver, where they patrolled the sinusoids. Exploring the requirements for liver Trm cell induction, we showed that by combining dendritic cell-targeted priming with liver inflammation and antigen recognition on hepatocytes, high frequencies of Trm cells could be induced and these cells were essential for protection against malaria sporozoite challenge. Our study highlights the immune potential of liver Trm cells and provides approaches for their selective transfer, expansion, or depletion, which may be harnessed to control liver infections or autoimmunity. PMID- 27692610 TI - Bile Acids Control Inflammation and Metabolic Disorder through Inhibition of NLRP3 Inflammasome. AB - Reciprocal interactions between the metabolic system and immune cells play pivotal roles in diverse inflammatory diseases, but the underlying mechanisms remain elusive. The activation of bile acid-mediated signaling has been linked to improvement in metabolic syndromes and enhanced control of inflammation. Here, we demonstrated that bile acids inhibited NLRP3 inflammasome activation via the TGR5 cAMP-PKA axis. TGR5 bile acid receptor-induced PKA kinase activation led to the ubiquitination of NLRP3, which was associated with the PKA-induced phosphorylation of NLRP3 on a single residue, Ser 291. Furthermore, this PKA induced phosphorylation of NLRP3 served as a critical brake on NLRP3 inflammasome activation. In addition, in vivo results indicated that bile acids and TGR5 activation blocked NLRP3 inflammasome-dependent inflammation, including lipopolysaccharide-induced systemic inflammation, alum-induced peritoneal inflammation, and type-2 diabetes-related inflammation. Altogether, our study unveils the PKA-induced phosphorylation and ubiquitination of NLRP3 and suggests TGR5 as a potential target for the treatment of NLRP3 inflammasome-related diseases. PMID- 27692612 TI - K+ Efflux-Independent NLRP3 Inflammasome Activation by Small Molecules Targeting Mitochondria. AB - Imiquimod is a small-molecule ligand of Toll-like receptor-7 (TLR7) that is licensed for the treatment of viral infections and cancers of the skin. Imiquimod has TLR7-independent activities that are mechanistically unexplained, including NLRP3 inflammasome activation in myeloid cells and apoptosis induction in cancer cells. We investigated the mechanism of inflammasome activation by imiquimod and the related molecule CL097 and determined that K+ efflux was dispensable for NLRP3 activation by these compounds. Imiquimod and CL097 inhibited the quinone oxidoreductases NQO2 and mitochondrial Complex I. This induced a burst of reactive oxygen species (ROS) and thiol oxidation, and led to NLRP3 activation via NEK7, a recently identified component of this inflammasome. Metabolic consequences of Complex I inhibition and endolysosomal effects of imiquimod might also contribute to NLRP3 activation. Our results reveal a K+ efflux-independent mechanism for NLRP3 activation and identify targets of imiquimod that might be clinically relevant. PMID- 27692611 TI - Optimal Generation of Tissue-Resident but Not Circulating Memory T Cells during Viral Infection Requires Crosspriming by DNGR-1+ Dendritic Cells. AB - Despite the crucial role of tissue-resident memory T (Trm) cells in protective immunity, their priming remains poorly understood. Here, we have shown differential priming requirements for Trm versus circulating memory CD8+ T cells. In vaccinia cutaneous-infected mice, DNGR-1-mediated crosspresentation was required for optimal Trm cell priming but not for their skin differentiation or for circulating memory T cell generation. DNGR-1+ dendritic cells (DCs) promoted T-bet transcription-factor induction and retention of CD8+ T cells in the lymph nodes (LNs). Inhibition of LN egress enhanced Trm cell generation, whereas genetic or antibody blockade of DNGR-1 or specific signals provided during priming by DNGR-1+ DCs, such as interleukin-12 (IL-12), IL-15, or CD24, impaired Trm cell priming. DNGR-1 also regulated Trm cell generation during influenza infection. Moreover, protective immunity depended on optimal Trm cell induction by DNGR-1+ DCs. Our results reveal specific priming requirements for CD8+ Trm cells during viral infection and vaccination.

AB - OBJECTIVE: Selecting probable idiopathic normal pressure hydrocephalus (INPH) patients for shunt insertion presents a challenge because of coexisting comorbidities and other conditions that could mimic NPH. The characteristic appearance of DESH (Disproportionately Enlarged Subarachnoid Space Hydrocephalus) on brain imaging has been shown to have a high positive predictive value in identifying shunt responsive INPH patients (SINPHONI trial). However, the negative predictive value of this radiological sign was not clearly demonstrated. The aim of the present study was to calculate the negative predictive value of the DESH sign. METHODS: A single centre study of probable INPH patients, who underwent ventriculoperitoneal (VP) shunt insertion. Shunt responsive INPH patients were identified as those having improvement in their walking speed, neuropsychological assessment and continence one year post operatively. Preoperative images were reviewed for DESH sign. Negative and Positive Predictive Values (NPV and PPV) of DESH sign were determined post analysis. RESULTS: A total of 103 probable INPH patients were included (31 were DESH positive (30%) and 72 were DESH negative (70%)). A total of 78 patients showed measurable improvement one year post shunt insertion (76%); 24 (31%) of these patients were DESH positive and 54 (69%) were DESH negative (p=<0.001). Therefore, the DESH sign had an estimated PPV of 77% and NPV of 25%. CONCLUSION: DESH sign demonstrates a low negative predictive value. We conclude that DESH negative patients should still undergo prognostic tests for iNPH, such as an extended lumbar drainage protocol, and should not be excluded from shunt insertion.

AB - Thallium intoxication was reported in cases with accidental ingestion, suicide attempt, and criminal adulteration. Reported cases were mostly one-time ingestion, therefore, the clinical course of divisional ingestion has not been fully known. Here, we report a case with two-step thallium intoxication manifesting as tardily accelerated neurologic deterioration. A 16-year-old adolescent was cryptically poisoned with thallium sulfate twice at an interval of 52days. After the first ingestion, neurologic symptoms including visual loss, myalgia, and weakness in legs developed about 40days after the development of acute gastrointestinal symptoms and alopecia. After the second ingestion, neurologic symptoms deteriorated rapidly and severely without gastrointestinal or cutaneous symptoms. Brain magnetic resonance imaging exhibited bilateral optic nerve atrophy. Nerve conduction studies revealed severe peripheral neuropathies in legs. Thallium intoxication was confirmed by an increase in urine thallium egestion. Most of the neurologic manifestations ameliorated in two years, but the visual loss persisted. The source of thallium ingestion was unraveled afterward because a murder suspect in another homicidal assault confessed the forepast adulteration. This discriminating clinical course may be attributable to the cumulative neurotoxicity due to the longer washout-time of thallium in the nervous system than other organs. It is noteworthy that the divisional thallium intoxication may manifest as progressive optic and peripheral neuropathy without gastrointestinal or cutaneous symptoms.

AB - During early language development native phonotactics are acquired in a 'bottom up' fashion, relying on exquisite auditory differentiation skills operational from birth. Since basic lexico-semantic abilities have been demonstrated from 6 months onwards, 'top-down' influences on phonotactic learning may complement the extraction of transitional probabilities in phonotactic learning. Such a bidirectional acquisition strategy predicts, that familiarization with (proto)words should affect processing of untrained word-forms of similar phonological structure. We investigated 6-month-old infants undergoing an associative training to establish a pseudoword-pseudoobject link. Comparison between pre- and post-training responses to trained and untrained items allowed investigating training effects. Additionally phonotactic status (50% legal, 50% illegal with regard to German) allowed investigating influences of previous language experience. EEG and functional near-infrared spectroscopy (fNIRS) provided measures of electrophysiological and hemodynamic responses. We find evidence for a robust effect of associative training on pseudoword processing when presented in isolation. This transferred to untrained items. Previous linguistic experience showed a much weaker effect. Taken together the results suggest that sensitivity to phonotactic contrasts is present at 6 months, but that acceptance as lexical candidates is rapidly modulated when word forms following non-native phonotactics become potentially meaningful due to repeated exposure in a semantic context. PMID- 27692616 TI - The Intracellular Cholesterol Landscape: Dynamic Integrator of the Immune Response. AB - Cholesterol has typically been considered an exogenous, disease-related factor in immunity; however, recent literature suggests that a paradigm shift is in order. Sterols are now recognized to ligate several immune receptors. Altered flux through the mevalonic acid synthesis pathway also appears to be a required event in the antiviral interferon (IFN) response of macrophages and in the activation, proliferation, and differentiation of T cells. In this review, evidence is discussed that suggests an intrinsic, 'professional' role for sterols and oxysterols in macrophage and T-cell immunity. Host defense may have been the original selection pressure behind the development of mechanisms for intracellular cholesterol homeostasis. Functional coupling between sterol metabolism and immunity has fundamental implications for health and disease. PMID- 27692618 TI - Atmospheric Spray Freeze-Drying: Numerical Modeling and Comparison With Experimental Measurements. AB - Atmospheric spray freeze-drying (ASFD) represents a novel approach to dry thermosensitive solutions via sublimation. Tests conducted with a second generation ASFD equipment, developed for pharmaceutical applications, have focused initially on producing a light, fine, high-grade powder consistently and reliably. To better understand the heat and mass transfer physics and drying dynamics taking place within the ASFD chamber, 3 analytical models describing the key processes are developed and validated. First, by coupling the dynamics and heat transfer of single droplets sprayed into the chamber, the velocity, temperature, and phase change evolutions of these droplets are estimated for actual operational conditions. This model reveals that, under typical operational conditions, the sprayed droplets require less than 100 ms to freeze. Second, because understanding the heat transfer throughout the entire freeze-drying process is so important, a theoretical model is proposed to predict the time evolution of the chamber gas temperature. Finally, a drying model, calibrated with hygrometer measurements, is used to estimate the total time required to achieve a predefined final moisture content. Results from these models are compared with experimental data. PMID- 27692619 TI - On the Design of a Fuzzy Logic-Based Control System for Freeze-Drying Processes. AB - This article is focused on the design of a fuzzy logic-based control system to optimize a drug freeze-drying process. The goal of the system is to keep product temperature as close as possible to the threshold value of the formulation being processed, without trespassing it, in such a way that product quality is not jeopardized and the sublimation flux is maximized. The method involves the measurement of product temperature and a set of rules that have been obtained through process simulation with the goal to obtain a unique set of rules for products with very different characteristics. Input variables are the difference between the temperature of the product and the threshold value, the difference between the temperature of the heating fluid and that of the product, and the rate of change of product temperature. The output variables are the variation of the temperature of the heating fluid and the pressure in the drying chamber. The effect of the starting value of the input variables and of the control interval has been investigated, thus resulting in the optimal configuration of the control system. Experimental investigation carried out in a pilot-scale freeze-dryer has been carried out to validate the proposed system. PMID- 27692620 TI - Solubility Advantage (and Disadvantage) of Pharmaceutical Amorphous Solid Dispersions. AB - The solubility of a drug is ultimately governed by its chemical potential as it is present in the undissolved solute. For a pharmaceutical amorphous solid dispersion (ASD), its solubility depends on the state and composition of the undissolved solute when the ASD is equilibrated with water. Concerning the undissolved solute phase that can contain up to 3 components (drug, polymer, and water), we developed a complete thermodynamic model to calculate the chemical potential of a drug in the multicomponent, amorphous system. This approach enables the estimation of the true solubility advantage of ASD from calorimetric measurements and moisture sorption isotherms. Both theoretical estimation and experimental studies, using indomethacin (IMC)/Eudragit E ASD systems, show that the solubility advantage of the amorphous IMC is significantly reduced through ASD formation and water partitioning. For the ASD with 70% drug loading, the solubility of IMC is lower than its crystalline counterpart. Our results show that stabilization through the ASD formation and water sorption can be manifested by the lowering of drug solubility; they demonstrate that the core property in ASD development is the drug chemical potential, which is essentially the thermodynamic driving force and can be quantitated using the model presented in this work. PMID- 27692621 TI - Use of King Vision(r) videolaryngoscope in an unanticipated difficult airway in an adult patient with giant vallecular cyst, a case report. AB - Laryngeal cysts are largely asymptomatic and typically described in the context of incidental discovery on routine laryngoscopy. These cysts, in adults are even rarer and can have catastrophic consequences in an anaesthetized patient if airway management is inappropriate. We describe a case of difficult endotracheal intubation and the treatment of an adult patient with an asymptomatic, giant vallecular cyst that was discovered during rapid-sequence induction of general anesthesia in urgent surgery. In conclusion, vallecular cysts can cause extreme problems in securing the airway. It is important to avoid complications associated with repeated attempts at intubation, airway loss, or cyst rupture causing difficulty visualizing vocal cords and aspiration. The use of King Vision(r) videolaryngoscope is a good alternative in these cases. Close attention to logistics and the immediate availability of an otolaryngologist is vital. PMID- 27692622 TI - Establishing the association between nonnutritive sucking behavior and malocclusions: A systematic review and meta-analysis. AB - BACKGROUND: The authors studied the effects of nonnutritive sucking behavior (NNSB) on malocclusions through a systematic review of association (etiology). TYPES OF STUDIES REVIEWED: The authors performed a 3-step search strategy, including electronic searches. Studies of healthy participants with a history of active or previous NNSB, for whom specific malocclusion outcomes had been assessed, were eligible for inclusion. The authors considered before-and-after studies, prospective and retrospective (longitudinal) studies, case-control studies, and analytical cross-sectional studies. They excluded reviews, text- and opinion-based articles, conference abstracts, case reports, case-series, and descriptive cross-sectional studies. The authors, using standardized instruments, independently assessed methodological quality and extracted data from the included studies. In situations for which there were sufficient studies, the authors conducted meta-analyses using the random-effects model, supplemented with the fixed-effects model in situations for which statistical heterogeneity was less than 50%, which the authors assessed using the I2 statistic. RESULTS: The authors included 15 identified studies. They found that NNSB was associated with varying risks of developing malocclusions. Pacifier suckers are less likely to develop an increased overjet compared with digit suckers, although the results of a meta-analysis of 7 studies whose investigators had assessed posterior crossbite in the primary dentition demonstrated a significant association with pacifier sucking over digit sucking (n = 5,560; risk ratio, 1.42; 95% confidence interval, 1.18-1.70; P = .0001). Longer duration of NNSB was associated with an increased risk of developing malocclusions. Across-study heterogeneity likely resulted from methodological and sample size differences. CONCLUSIONS: The authors of this study have confirmed the association between NNSB and the development of malocclusions. This study provides the highest level of evidence on this topic. Pacifiers were associated with a higher risk of developing most malocclusion features when compared with digit sucking. PRACTICAL IMPLICATIONS: Though malocclusions are of multifactorial etiology, clinicians should inform parents and caregivers about the dental risks of NNSB, an environmental factor that is modifiable. NNSB should be discouraged in order to avoid the development of malocclusions. Future studies should adopt standardized, universally agreed and accepted definitions and classifications when measuring and reporting orthodontic outcome measures. This will help achieve across-study homogeneity. PMID- 27692623 TI - [Estimation of arterial oxygen saturation in relation to altitude]. AB - BACKGROUND AND OBJECTIVES: Arterial Oxygen Saturation (AOS) predicts altitude sickness. OBJECTIVES: To estimate the AOS values with relation to altitude. Furthermore, make a graph to use during activity which assesses the AOS for each altitude and the normal range. PATIENTS AND METHOD: Values of AOS were assessed during eight high mountain activities in the Alps, Himalaya, Caucasus and Andes; 53 mountaineers participated, 17 of them in more than one activity; 761 measurements of AOS were registered. RESULTS: A Logistic Regression Model was made to estimate the AOS values dependent on altitude, adjusted to possible related factors. A strong lineal relationship exists between altitude and AOS (R2=.83, P<.001); .7 points more in women. The AOS in a particular altitude is not related to age, weight, height, smoking, heart rate, or even with previous experiences in mountains. The calculation of the AOS responds to the follow equation: Blood Oxygen Saturation=103.3-(altitude * .0047)+(Z), being Z=.7 in men and 1.4 in women. A scatter plot was made to relate the estimated altitude with the AOS, with their normal limits values: percentiles 2.5 and 97.5. CONCLUSIONS: The simple calculation of the AOS estimated for a particular altitude with the proposed graphic can help in the early decision-making onsite.

AB - INTRODUCTION AND OBJECTIVES: Left-sided native valve infective endocarditis (LNVIE) epidemiology has been modified as a result of the increase in average age. The aim of our study is to analyze the influence of age and the presence of predisposing heart disease in the prognosis of these patients. METHODS: We analyzed a series of 257 cases of LNVIE depending on their age (greater than or equal to 70 years old), both in the overall series and in the subgroup of patients without predisposing heart disease. RESULTS: Mean age was 54.6 (18.6) years. There was an increase in the percentage of cases of older patients between 1987-2000 and 2001-2014 (9.8 vs. 34.8%, P<.001). These patients present higher prevalence of degenerative valves (50 vs. 22.8%) or not predisposing heart disease (50 vs. 39.9%), P<.001, health-care associated episodes (41.8 vs. 23.6%, P=.016), lower rate of surgery (43.7 vs. 63.8%, P=.005) and higher in-hospital mortality (39.1 vs. 20.7%, P=.003), with no differences in comorbidities. Older patients who did not have predisposing heart disease also suffered higher in hospital mortality (47 vs. 22%, P=.01). Age greater than or equal to 70 years old is an independent predictor of mortality in patients with LNVIE (OR 2.53, 95% CI 1.24-5.15, P=.011), as in those without previous heart disease (OR 3.98, 95% CI 1.49-10.62, P=.006). CONCLUSIONS: Patients of age greater than or equal to 70 years old and who suffer an LNVIE are becoming more frequent and have a worse prognosis with a lower rate of surgery and higher rates of in-hospital mortality. PMID- 27692626 TI - The utility of a "trauma 1 OP" activation at a level 1 pediatric trauma center. AB - PURPOSE: To expedite flow of injured children suspected to require operative intervention, a "trauma 1 OP" (T1OP) activation classification was created. The purpose of this study was to review this strategy at a level 1 pediatric trauma center. METHODS: A retrospective review of T1OP activations between 2003 and 2015 was performed. Children suspected of requiring neurosurgical intervention were classified as trauma 1 OP neuro (T1OP(N)). Comparisons were made to trauma 1 (T1) patients who required emergent operative intervention, excluding orthopedic injuries. RESULTS: Overall, 461 T1OP activations occurred (72% T1OP(N)) compared to 129 T1 activations requiring emergent surgery. Demographics were not significantly different between groups, although T1OP patients were slightly younger and more often experienced falls or were victims of abuse. Compared to T1 activations, T1OP activations had a significantly higher mortality rate (21% vs. 7%, p<0.001). Repeat head imaging was more common in the T1OP(N) group compared to imaged children in the T1 group (20% vs. 37%, p=0.05). T1OP(N) patients more often went directly to the OR (45% vs. 33%, p=0.02) and did so in a significantly faster period of time (32min vs. 53min, p<0.001). CONCLUSIONS: Use of the T1OP activations appropriately triaged surgical patients, resulting in significantly faster transport times to the OR. LEVEL OF EVIDENCE: II, prognosis study. PMID- 27692627 TI - Does a large abdominal wall defect affect lung growth? AB - BACKGROUND/PURPOSE: Respiratory distress in babies with large abdominal wall defects suggests a relationship to decreased diaphragmatic movement. We evaluated pulmonary development in a fetal lamb gastroschisis model. METHODS: We created gastroschisis in 25 fetal lambs at 60days gestation (group A). Controls were 14 nonoperated lambs. (Group B) were all delivered at term. Lung volume, histology, and type 1 (AT1)/type 2 (AT2) cell ratios (AT1 ratio) were determined. We subdivided group A, comparing lambs with a large defect and scoliosis [group A (S)] with the remainder [group A (NS)]. RESULTS: Twenty-five lambs survived (11 fetuses in group A and 14 fetuses in group B). Lung volume in group A (S) was less than in group A (NS) (p<0.05). The AT1 ratio in group A was lower than in group B (p<0.01), without any difference in radial alveolar counts (RACs) or alveolar growth, and no association between scoliosis and alveolar differentiation. CONCLUSION: Gastroschisis in a sheep model reduces the AT1 ratio but not the RAC. Severe scoliosis affects lung volume but not the AT1 ratio, suggesting reduced diaphragmatic movement in fetuses with large abdominal defects.

AB - OBJECTIVE: To examine how food store environments can promote healthful eating, including (1) preferences for a variety of behavioral economics strategies to promote healthful food purchases, and (2) the cross-sectional association between the primary food store where participants reported shopping, dietary behaviors, and body mass index. METHODS: Intercept survey participants (n = 342) from 2 midsized eastern North Carolina communities completed questionnaires regarding preferred behavioral economics strategies, the primary food store at which they shopped, and consumption of fruits, vegetables, and sugary beverages. RESULTS: Frequently selected behavioral economic strategies included: (1) a token and reward system for fruit and vegetable purchases; and (2) price discounts on healthful foods and beverages. There was a significant association between the primary food store and consumption of fruits and vegetables (P = .005) and sugary beverages (P = .02). CONCLUSIONS AND IMPLICATIONS: Future studies should examine associations between elements of the in-store food environment, purchases, and consumption. PMID- 27692629 TI - Engaging Caregivers in School-Based Obesity Prevention Initiatives in a Predominantly Latino Immigrant Community: A Qualitative Analysis. AB - OBJECTIVES: To explore caregiver perceptions of, and barriers and facilitators to, their involvement in school-based obesity prevention programs in underserved Latino immigrant communities. METHODS: Focus groups discussions were conducted with caregivers (n = 42) at 7 elementary schools with an academic partnership based obesity prevention program. Thematic analysis was used to identify key findings in the data. RESULTS: Caregivers described their role as (1) learners of new and often complex health information using their children as primary messengers and (2) champions within their homes in which healthier choices are assimilated. Barriers to involvement included lack of time, financial pressures, unhealthy family practices, and concern that attempts to engage peers would be perceived as intrusive. Facilitators included assurance that stigmatizing health issues would be addressed with sensitivity. CONCLUSIONS AND IMPLICATIONS: Caregiver involvement in obesity prevention may be fostered by transmitting information through children, addressing cultural barriers, and avoiding potentially stigmatizing approaches to delivering health messages. PMID- 27692630 TI - Employees' Expectations of Internet-Based, Workplace Interventions Promoting the Mediterranean Diet: A Qualitative Study. AB - OBJECTIVE: Explore employees' perceptions of ability to follow the Mediterranean diet (MedDiet), preferences for setting goals if asked to follow the MedDiet, and expectations of an Internet-based, workplace MedDiet intervention. DESIGN: Seven focus groups to guide intervention development. SETTING: Four workplaces (business/professional services, government branches) in Southwest England. PARTICIPANTS: Employees (n = 29, 51.7% women), ages 24-58 years. PHENOMENON OF INTEREST: Ability to follow the MedDiet; preferences for goal-setting if asked to follow the MedDiet; intervention content. ANALYSIS: Data were analyzed with the use of thematic analysis. RESULTS: Participants perceived that adhering to some MedDiet recommendations would be challenging and highlighted cost, taste, and cooking skills as adherence barriers. Behavior change preferences included a tailored approach to goal-setting, reviewing goal progress via a website/smartphone app, and receiving expert feedback via an app/website/text/face-to-face session. Desirable features of an Internet-based MedDiet application included recipes, interactivity, nutritional information, shopping tips, cost-saving information, and a companion smartphone app. Engaging in social support was deemed important to facilitate adherence. CONCLUSIONS AND IMPLICATIONS: An Internet-based, workplace MedDiet intervention should address adherence barriers, utilize a tailored approach to setting and reviewing goals, and activate social support to facilitate adherence. These findings provide insights to planning to promote the MedDiet in non-Mediterranean regions. PMID- 27692631 TI - [Map of resources and healthcare needs for patients with dyslipidaemia in Spain: The MADI study]. AB - INTRODUCTION: Dyslipidaemia is a major modifiable determining factor of vascular risk and, despite this, a significant number of patients do not achieve lipid goals. The aim of this study is to describe the resources and current needs in clinical practice in Spain, through an analysis of management, organisation and the patient care circuit of dyslipidaemia patient. METHODS: A descriptive, cross sectional, multicentre study, using a questionnaire, was conducted on physicians, 266 in primary care (PC) and 258 in specialised care (SC), who attended patients with dyslipidaemia in hospitals and centres within the National Health System. Probabilistic analyses were performed, stratifying by care-level, existence of a lipid unit (LU), and geographic area. RESULTS: Observed differences were mostly due to geographic location, rather than the existence of LU in the referral hospitals. Most system deficiencies were found in the southern provinces of the country. Nearly all primary care physicians declared that they diagnose, manage and control dyslipidaemia patients, but a general agreement was lacking for diagnostic and referral criteria. The scarce use of a shared protocol between PC and SC showed evidence of poor coordination between health care providers. Furthermore, there was a remarkably low proportion of patients receiving health care education for their disease. CONCLUSIONS: This study emphasises the need to identify weaknesses in the dyslipidaemia patient care circuit, and to perform the appropriate remedial actions, in particular, to promote coordination between levels of care and to foster patient education about their disease.

AB - Non-alcoholic fatty liver disease (NAFLD) comprises a series of histologically lesions similar to those induced by alcohol consumption in people with very little or no liver damage. The importance of NAFLD is its high prevalence in the Western world and, from the point of view of the liver, in its gradual progression from steatosis to steatohepatitis, cirrhosis, and liver cancer. During the last decade it has been observed that NAFLD leads to an increased cardiovascular risk with acceleration of arteriosclerosis and events related to it, being the main cause of its morbidity and mortality. This review, updated to January 2016, consists of two parts, with the first part analysing the association of NAFLD with cardiovascular disease. PMID- 27692634 TI - [Inflammation inhibits vascular fibulin-5 expression: Involvement of transcription factor SOX9]. AB - INTRODUCTION: Fibulin-5 (FBLN5) is an elastogenic protein critically involved in extracellular matrix (ECM) remodelling, a key process in abdominal aortic aneurysm (AAA). However, the possible contribution of FBLN5 to AAA development has not been addressed. METHODS: Expression levels were determined by real-time PCR and Western blot in human abdominal aorta from patients with AAA or healthy donors, as well as in human aortic vascular smooth muscle cells (VSMC). Lentiviral transduction, transient transfections, and chromatin immunoprecipitation (ChIP) assays were also performed. RESULTS: The expression of FBLN5 in human AAA was significantly lower than in healthy donors. FBLN5 mRNA and protein levels and their secretion to the extracellular environment were down regulated in VSMC exposed to inflammatory stimuli. Interestingly, FBLN5 transcriptional activity was inhibited by TNFalpha and lipopolysaccharide (LPS), and depends on a SOX response element. In fact, SOX9 expression was reduced in VMSC induced by inflammatory mediators and in human AAA, and correlated with that of FBLN5. Furthermore, SOX9 over-expression limited the reduction of FBLN5 expression induced by cytokines in VSMC. Finally, it was observed that SOX9 interacts with FBLN5 promoter, and that this binding was reduced upon TNFalpha exposure. CONCLUSIONS: FBLN5 downregulation in human AAA could contribute to extracellular matrix remodelling induced by the inflammatory component of the disease. PMID- 27692635 TI - [Is regression of atherosclerotic plaque possible?] AB - As it is well-known, a thrombus evolving into a disrupted/eroded atherosclerotic plaque causes most acute coronary syndromes. Plaque stabilization via reduction of the lipid core and/or thickening of the fibrous cap is one of the possible mechanisms accounted for the clinical benefits displayed by different anti atherosclerotic strategies. The concept of plaque stabilization was developed to explain how lipid-lowering agents could decrease adverse coronary events without substantial modifications of the atherosclerotic lesion ('angiographic paradox'). A number of imaging modalities (vascular ultrasound and virtual histology, MRI, optical coherence tomography, positron tomography, etc.) are used for non invasive assessment of atherosclerosis; most of them can identify plaque volume and composition beyond lumen stenosis. An 'aggressive' lipid-lowering strategy is able to reduce the plaque burden and the incidence of cardiovascular events; this may be attributable, at least in part, to plaque-stabilizing effects.

AB - PURPOSE: The objective of this short review is to evaluate the efficacy of ferric pyrophosphate citrate and to determine its place in therapy based on the current published literature. METHODS: A literature search was conducted and pared down to yield 4 placebo controlled Phase II and III clinically relevant trials. FINDINGS: Ferric pyrophosphate citrate is a new intradialytic iron supplementation product that has been found to reduce the dose of erythropoiesis stimulating agents and intravenous iron supplementation and to increase serum ferritin concentrations. IMPLICATIONS: This agent may be administered to patients with stage 5 chronic kidney disease receiving hemodialysis as a new iron supplementation option to maintain hemoglobin, transferrin saturation, and ferritin concentrations. PMID- 27692638 TI - Single- and Multiple-dose Pharmacokinetics of a Lorcaserin Extended-release Tablet. AB - PURPOSE: Lorcaserin is a serotonin 2C receptor agonist indicated for chronic weight management as an adjunct to diet and exercise. The initial approved formulation is a 10-mg, immediate-release (IR) tablet for administration BID. These studies investigated the single- and multiple-dose pharmacokinetic properties of a new, recently US Food and Drug Administration-approved, extended release, 20-mg once-daily formulation. METHODS: We performed 2 separate 2-period, 2-sequence crossover studies in 36 healthy adults: a study comparing the IR formulation to the extended-release formulation under fasting conditions and a study comparing the extended-release formulation under fed and fasted conditions. FINDINGS: Compared with lorcaserin IR, the Tmax after a single dose of lorcaserin extended-release was greater (median, 12 vs 3 hours), and the Cmax was 26% lower (38.8 vs 52.3 ng/mL). AUC data were bioequivalent for the 2 formulations in both single- and multiple-dose regimens, confirming no formulation effect on lorcaserin bioavailability. In fasted and fed conditions, Tmax after a single dose was identical (median, 12 hours), but Cmax was approximately 45% higher in the fed state (mean, 38.5 ng/mL fasted vs 56.1 ng/mL fed). However, at steady state, Cmax and AUC were determined to be bioequivalent between the fasted and fed states, indicating no clinically relevant food effect on the pharmacokinetic properties of lorcaserin extended-release. The safety profile was consistent between the 2 formulations. IMPLICATIONS: Overall, the results indicate that lorcaserin extended-release is a suitable once-daily alternative to the approved IR BID formulation. PMID- 27692639 TI - 7,10-Diphenylfluoranthene grafted polysiloxane as a highly selective stationary phase for gas chromatography. AB - A novel 7,10-diphenylfluoranthene grafted polysiloxane (DPFP) was synthesized and statically coated on a fused-silica capillary column. High column efficiency (3864 plates per m) was achieved for naphthalene at 120 degrees C. Thermo gravimetric analysis showed that the DPFP polymer began to decompose at 380 degrees C. The chromatogram of polyethylene pyrolysis products indicated that the maximum allowable temperature of the DPFP column could reach 360 degrees C. By relying on its specific pi-pi stacking and dipole-induced dipole interactions with aromatic solutes, the DPFP stationary phase achieved excellent resolution for substituted benzene and aromatic hydrocarbons with satisfactory peak shapes, as well as showed superiority to current stationary phases that failed to resolve some critical pairs. Moreover, DPFP also showed good selectivity and resolving ability for Grob test mixtures, fatty acid esters, and ethers. PMID- 27692640 TI - Sequence-dependent separation of trinucleotides by ion-interaction reversed-phase liquid chromatography-A structure-retention study assisted by soft-modelling and molecular dynamics. AB - We studied sequence-dependent retention properties of synthetic 5'-terminal phosphate absent trinucleotides containing adenine, guanine and thymine through reversed-phase liquid chromatography (RPLC) and QSRR modelling. We investigated the influence of separation conditions, namely mobile phase composition (ion interaction agent content, pH and organic constituent content), on sequence dependent separation by means of ion-interaction RPLC (II-RPLC) using two types of models: experimental design-artificial neural networks (ED-ANN), and linear regression based on molecular dynamics data. The aim was to determine those properties of the above-mentioned analytes responsible for the retention dependence of the sequence. Our results show that there is a deterministic relation between sequence and II-RPLC retention properties of the studied trinucleotides. Further, we can conclude that the higher the content of ion interaction agent in the mobile phase, the more prominent these properties are. We also show that if we approximate the polar component of solvation energy in QSRR by the electrostatic work in transferring molecules from vacuum to water, and the non-polar component by the solvent accessible surface area, these parameters best describe the retention properties of trinucleotides. There are some exceptions to this finding, namely sequences 5'-NAN-3', 5'-ANN-3', 5'-TGN 3', 5'-NTA-3'and 5'-NGA-3' (N stands for generic nucleotide). Their role is still unknown, but since linear regression including these specific constellations showed a higher observable variance coverage than the model with only the basic descriptors, we may assume that solvent-analyte interactions are responsible for the exceptional behaviour of 5'-NAN-3' & 5'-ANN-3' trinucleotides and some intramolecular interactions of neighbouring nucleobases for 5'-TGN-3', 5'-NTA 3'and 5'-NGA-3' trinucleotides. PMID- 27692641 TI - Preparation and evaluation of micro and meso porous silica monoliths with embedded carbon nanoparticles for the extraction of non-polar compounds from waters. AB - A novel hybrid micro and meso porous silica monolith with embedded carbon nanoparticles (Si-CNPs monolith) was prepared inside a fused silica capillary (3cm in length) and used as a sorbent for solid-phase microextraction. The hybrid monolithic capillary was synthetized by hydrolysis and polycondensation of a mixture of tetraethoxysilane (TEOS), ethanol, and three different carbon nanoparticles such as carboxylated single-walled carbon nanotubes (c-SWCNTs), carboxylated multi-walled carbon nanotubes (c-MWCNTs), and oxidized single-walled carbon nanohorns (o-SWNHs) via a two-step catalytic sol-gel process. Compared with silica monolith without carbon nanoparticles, the developed monolithic capillary column exhibited a higher extraction efficiency towards the analytes which can be ascribed to the presence of the carbon nanoparticles. In this regard, the best performance was achieved for silica monolith with embedded c MWCNTs. The resulted monolithic capillaries were also characterized by scanning electron microscopy (SEM), elemental analysis and nitrogen intrusion porosimetry. Variables affecting to the preparation of the sorbent phase including three different carbon nanoparticles and extraction parameters were studied in depth using polycyclic aromatic hydrocarbons (PAHs) as target analytes. Gas chromatography-mass spectrometry was selected as instrumental technique. Detection limits range from 0.1 to 0.3MUgL-1, and the inter-extraction units precision (expressed as relative standard deviation) is between 5.9 and 14.4%. PMID- 27692642 TI - Implant stability after sinus floor augmentation with deproteinized bovine bone mineral particles of different sizes: a prospective, randomized and controlled split-mouth clinical trial. AB - The aim of this study was to compare implant stability after maxillary sinus floor augmentation using small- or large-sized particles of Bio-Oss. Ten partially edentulous patients requiring bilateral maxillary sinus floor augmentation were enrolled. The subjects were assigned randomly to one of two experimental groups: maxillary sinus was filled with 0.25-1mm particle size (small particles) and the contralateral side was filled with 1-2mm particle size (large particles). After 8 months, a total of 25 implants were placed in the two maxillary sinuses. Primary implant stability was measured immediately after implant placement (T0) using a torque controller and resonance frequency analysis (RFA). Six months after implant placement (T1), the implant stability was measured again. There were no postoperative complications in either particle size group, and the success rate for implant survival was 100%. All implants showed good primary stability as evidenced by high torque for the implant insertion in both groups. RFA revealed high ISQ values for all implants installed in both groups at T0 and T1. These results indicate that the size of the Bio-Oss particles (small and large) did not influence implant stability in the maxillary sinus. Indeed, small and large particles of Bio-Oss presented optimal properties, supporting their possible use as osteoconductive grafts.

PMID- 27692645 TI - Separation properties of the MIL-125(Ti) Metal-Organic Framework in high performance liquid chromatography revealing cis/trans selectivity. AB - Monodisperse MIL-125(Ti) Metal-Organic Framework crystals were synthesized and studied as stationary phase in high performance liquid chromatography (HPLC). Different pure compounds and model mixtures (including stereoisomer mixtures) were injected from which chromatographic parameters, including selectivities and resolution factors, were determined to evaluate the adsorption properties and separation performance of MIL-125(Ti) in liquid phase. The MIL-125(Ti) framework displayed a trans selectivity for cis/trans difunctionalized cyclohexane molecules with high selectivity and resolution for 1,3-dimethylcyclohexane and 4 ethylcyclohexanol. The slurry-packed column was further characterized via van Deemter analysis. Fitting of the van Deemter equation through the experimental points allowed to define the contributions of the different processes to plate height with a significant proportion of the A-term, reflecting the importance of a good crystal packing. Although high in comparison to commercial HPLC stationary phases, a very good plate height of around 50MUm was found. PMID- 27692643 TI - Elimination of visceral leishmaniasis on the Indian subcontinent. AB - Visceral leishmaniasis is a serious public health problem on the Indian subcontinent, causing high morbidity and mortality. The governments in the region launched a visceral leishmaniasis elimination initiative in 2005. We review knowledge gaps and research priorities. Key challenges include low coverage of health services for those most at risk, drug resistance, the absence of a vaccine, and the complex biology of the sandfly-human host transmission cycle. Vector control is an essential component, but innovation in this field is insufficient. Substantial progress has been made in the area of diagnostic, therapeutic, and vaccine development, but there are still many hurdles to overcome. For visceral leishmaniasis elimination to become a reality, effective deployment of these existing and new tools is essential. A strong commitment at community level is imperative, and appropriate diagnostic and treatment services as well as effective epidemiological surveillance need to be ensured. PMID- 27692646 TI - Microfluidic nitrogen-assisted nanoelectrospray emitter: A monolithic interface for accurate mass measurements based on a single nozzle. AB - Nitrogen-assisted nanoelectrospray emitter (NANE) was developed to achieve accurate mass-to-charge ratio (m/z) measurements with a single monolithic nozzle. Deposition patterns of generated electrosprays from NANE confirmed their wrapped configurations. Additionally, the intensity of the sample ion and its ratio relative to a reference ion was inclined to focus on the central region of the spray; this trend further supported the existence of wrapped configurations. Further, the proposed NANE was fabricated from poly-(dimethylsiloxane) (PDMS) with octadecyltrichlorosilane modification to restrain the dissolution of PDMS monomers. Assist nitrogen flows were introduced to improve the ionization of reference ions. Moreover, the NANE could regulate the distribution of reference ions by microfluidic three dimensional hydrodynamic focusing. By regulating the distribution of reference ions, the ionization depression was reduced to some degree, and an improved sensitivity was accomplished compared with the mixing of sample and reference solutions. Achieved relative errors of m/z were between 0.2 4.5ppm and 5.2-9.2ppm for ten organic molecules and four biological macromolecules, respectively. Acceptable linear ranges were obtained in quantifications for rhodamine B and emamectin benzoate. Finally, the NANE was compatible with broad infusion rates (from 50nLmin-1 to 15MULmin-1) and solutions of different compositions (from 100% methanol to 100% water). Considering the comprehensive application of PDMS in microfluidics, the proposed NANE could be used as a compact and monolithic interface to achieve accurate m/z measurements. PMID- 27692647 TI - The effect of charged groups on hydrophilic monolithic stationary phases on their chromatographic properties. AB - In order to investigate the effect of charged groups present in hydrophilic monolithic stationary phases on their chromatographic properties, three charged hydrophilic monomers, i.e. N,N-dimethyl-N-acryloyloxyethyl-N-(3 sulfopropyl)ammonium betaine (SPDA), [2-(acryloyloxy)ethyl]trimethylammonium chloride (AETA), and 3-sulfopropyl acrylate potassium salt (SPA) were co polymerized with the crosslinker N,N'-methylenebisacrylamide (MBA), respectively. The physicochemical properties of the three resulting charged hydrophilic monolithic columns were evaluated using scanning electron microscopy, zeta potential analysis and micro-HPLC. High column efficiency was obtained on the three monolithic columns at a linear velocity of 1mm/s using thiourea as test compound. Comparative characterization of the three charged HILIC phases was then carried out using a set of model compounds, including nucleobases, nucleosides, benzoic acid derivatives, phenols, beta-blockers and small peptides. Depending on the combination of stationary phase/mobile phase/solute, both hydrophilic interaction and other potential secondary interactions, including electrostatic interaction, hydrogen-bonding interaction, molecular shape selectivity, could contribute to the over-all retention of the analytes. Because of the strong electrostatic interaction provided by the quaternary ammonium groups in the poly (AETA-co-MBA) monolith, this cationic HILIC monolith exhibited the strongest retention for benzoic acid derivatives and small peptides with distorted peak shapes and the weakest retention for basic beta-blockers. The sulfonyl groups on the poly (SPA-co-MBA) hydrophilic monolith could provide strong electrostatic attraction and hydrogen bonding for positively charged analytes and hydrogen donor/acceptor containing analytes, respectively. Therefore, basic drugs, nucleobases and nucleotides exhibited the strongest retention on this anionic monolith. Because of the weak but distinct cation exchange properties of the zwitterionic poly (SPDA-co-MBA) hydrophilic monolith, it exhibited the best separation for most test analytes (including phenols, beta-blockers and small peptides) in terms of selectivity, peak shape and analysis time. The poly (AETA co-MBA) hydrophilic monolithic column provides the best separation of nucleobases and nucleosides. These results could guide the selection and application of these charged HILIC monoliths in the future. PMID- 27692648 TI - Development of stable isotope dilution assays for the quantitation of intra- and extracellular folate patterns of Bifidobacterium adolescentis. AB - Folate-producing bifidobacteria have been studied extensively but appropriate methods for detailed quantitation of intra- and extracellular pteroylmono- and pteroylpolyglutamate patterns are lacking. Therefore, B. adolescentis DSM 20083T was cultivated in folate-free medium (FFM) for 24h to develop and validate stable isotope dilution assays (SIDAs) coupled with LC-MS/MS for the determination of 5 formyltetrahydrofolic acid (5-HCO-H4folate), 10-formylfolic acid (10-HCO-PteGlu), tetrahydrofolic acid (H4folate), folic acid (PteGlu) and 5-methyltetrahydrofolic acid (5-CH3-H4folate) including its di-, tri-, and tetraglutamic vitamers (5-CH3 H4PteGlu2-4). The respective monoglutamylated isotopologues labelled with deuterium were used as internal standards for quantitation. Limits of detection and quantitation (LOD/LOQ) were sufficiently low to quantify 48.2nmol L-1 5-CH3 H4folate (5.7/17nmolL-1) and 71.0nmolL-1 5-HCO-H4folate (10/30nmolL-1) as major folate vitamers extracellularly and 124nmolL-1 5-CH3-H4folate (3.4/10nmolL-1), 213nmolL-1 5-HCO-H4folate (4.8/14nmolL-1), and 61.4nmolL-1 H4folate (2.3/7.0nmolL 1) intracellularly after deconjugation. The major portion of native 5-CH3 H4folate vitamer was ascribed to its tetraglutamate ( > 95%). Concentrations of mono-, di-, tri-, and pentaglutamylated folates were below LOD or LOQ. Intra assay precision coefficients of variation (CVs) ranged from 7% (at a concentration of 53.9nmolL-1 for 5-CH3-H4PteGlu4), 15% (25.5nmolL-1 5-CH3 H4folate) to 18% (78.5nmolL-1 5-HCO-H4folate), extracellularly, and from 6% (60.7nmolL-1 5-CH3-H4PteGlu4), 7% (202nmolL-1 5-HCO-H4folate), 10% (67.1nmolL-1 H4folate) to 11% (127nmolL-1 5-CH3-H4folate), intracellularly. Inter-assay precision CVs ranged from 2% (54.7nmolL-1 5-CH3-H4PteGlu4), 3% (71nmolL-1 5-HCO H4folate) to 11% (48.2nmolL-1 5-CH3-H4folate), extracellularly, and from 1% (61.4nmolL-1 H4folate), 5% (213nmolL-1 5-HCO-H4folate), 6% (63.5nmolL-1 5-CH3 H4PteGlu4) to 10% (124nmolL-1 5-CH3-H4folate), intracellularly, thus showing excellent reproducibility. Recoveries for all analytes under study ranged between 81 and 113%. These newly developed methods enable reproducible, precise and sensitive quantitation of eight bacterially synthesized folate vitamers in two totally different matrices, including both monoglutamates and polyglutamates. Furthermore, we here present the first assay using solely monoglutamylated [2H4] 5-CH3-H4folate to quantify native polyglutamate patterns of this vitamer in bacteria which might replace time-consuming determination of monoglutamates in the future. PMID- 27692649 TI - Does the National Resident Match Program Rank List Predict Success in Emergency Medicine Residency Programs? AB - BACKGROUND: Emergency medicine (EM) residency programs use nonstandardized criteria to create applicant rank lists. One implicit assumption is that predictive associations exist between an applicant's rank and their future performance as a resident. To date, these associations have not been sufficiently demonstrated. OBJECTIVES: We hypothesized that a strong positive correlation exists between the National Resident Match Program (NRMP) match-list applicant rank, the United States Medical Licensing Examination (USMLE) Step 1 and In Training Examination (ITE) scores, and the graduating resident rank. METHODS: A total of 286 residents from five EM programs over a 5-year period were studied. The applicant rank (AR) was derived from the applicant's relative rank list position on each programs' submitted NRMP rank list. The graduation rank (GR) was determined by a faculty consensus committee. GR was then correlated to AR using a Spearman's partial rank correlation. Additional correlations were sought with a ranking of the USMLE Step Score (UR) and the ITE Score (IR). RESULTS: Combining data for all five programs, weak positive correlations existed between GR and AR, UR, and IR. The majority of correlations ranged between. When comparing GR and AR, there was a weak correlation of 0.13 (p = 0.03). CONCLUSION: Our study found only weak correlations between GR and AR, UR, and IR, suggesting that those variables may not be strong predictors of resident performance. This has important implications for EM programs considering the resources devoted to applicant evaluation and ranking. PMID- 27692650 TI - Predictors of Nondiagnostic Ultrasound for Appendicitis. AB - BACKGROUND: Ionizing radiation and cost make ultrasound (US), when available, the first imaging study for the diagnosis of suspected pediatric appendicitis. US is less sensitive and specific than computed tomography (CT) or magnetic resonance imaging (MRI) scans, which are often performed after nondiagnostic US. OBJECTIVES: We sought to determine predictors of nondiagnostic US in order to guide efficient ordering of imaging studies. METHODS: A prospective cohort study of consecutive patients 4 to 30 years of age with suspected appendicitis took place at an emergency department with access to 24/7 US, MRI, and CT capabilities. Patients with US as their initial study were identified. Clinical (i.e., duration of illness, highest fever, and right lower quadrant pain) and demographic (i.e., age and sex) variables were collected. Body mass index (BMI) was calculated based on Centers for Disease Control and Prevention criteria; BMI >85th percentile was categorized as overweight. Patients were followed until day 7. Univariate and stepwise multivariate logistic regression analysis was performed. RESULTS: Over 3 months, 106 patients had US first for suspected appendicitis; 52 (49%) had nondiagnostic US results. Eighteen patients had appendicitis, and there were no missed cases after discharge. On univariate analysis, male sex, a yearly increase in age, and overweight BMI were associated with nondiagnostic US (p < 0.05). In the multivariate model, only BMI (odds ratio 4.9 [95% CI 2.0-12.2]) and age (odds ratio 1.1 [95% CI 1.02-1.20]) were predictors. Sixty-eight percent of nondiagnostic US results occurred in overweight patients. CONCLUSION: Overweight and older patients are more likely to have a nondiagnostic US or appendicitis, and it may be more efficient to consider alternatives to US first for these patients. Also, this information about the accuracy of US to diagnose suspected appendicitis may be useful to clinicians who wish to engage in shared decision-making with the parents or guardians of children regarding imaging options for children with acute abdominal pain. PMID- 27692651 TI - Best Clinical Practice: Current Controversies in the Evaluation of Low-Risk Chest Pain with Risk Stratification Aids. Part 2. AB - BACKGROUND: Chest pain accounts for 10% of emergency department (ED) visits annually, and many of these patients are admitted because of potentially life threatening conditions. A substantial percentage of patients with chest pain are at low risk for a major cardiac adverse event (MACE). OBJECTIVE: We investigated controversies in the evaluation of patients with low-risk chest pain, including clinical scores, decision pathways, and shared decision-making. DISCUSSION: ED patients with chest pain who have negative biomarker results and nonischemic electrocardiograms are at low risk for MACE. With the large number of chest pain patients evaluated in the ED, several risk scores and pathways are in use based on history, electrocardiographic results, and biomarker results. The Thrombolysis in Myocardial Infarction and Global Registry of Acute Coronary Events scores are older rules with validation; however, they do not have adequate sensitivity or are not easy to use in the ED. The Vancouver chest pain and North American chest pain rules may be used for patients with undifferentiated chest pain in the ED. The Manchester Acute Coronary Syndromes rule uses eight factors, several of which are not available in the United States. The history, electrocardiography, age, risk factors, and troponin (HEART) score and pathway are easy to use, have high sensitivity and negative predictive values, and have better discriminatory capability for categorization. The use of pathways with shared decision-making involves the patient in management, shortens the duration of stay, and decreases risk to both the patient and the provider. CONCLUSIONS: Risk stratification of ED patients with chest pain has evolved, and there are many tools available. The HEART pathway, designed for ED use, has several attributes that provide safe and efficient care for patients with chest pain. PMID- 27692652 TI - Risk factors for developing prediabetes. PMID- 27692653 TI - [Analysis of an intervention to improve health outcomes in acute exacerbations of COPD in primary care]. AB - OBJECTIVE: To examine the impact of an intervention by Primary Care (PC) professionals of a Health District on the clinical outcomes for treating COPD exacerbations using a process and outcome indicators analysis (clinical audit). DESIGN: Observational, retrospective and prospective analysis cross-sectional audit of clinical practice SETTING: Malaga-Guadalhorce Sanitary District (DSMG). PARTICIPANTS: Patients with COPD exacerbations treated by the extra-hospital emergency services (n=523; 21% losses). INTERVENTIONS: Professional training in the usual clinical practice and inclusion of process indicators of COPD targets in relation to incentives. PRINCIPAL MEASUREMENTS: Comparison of external audit results (process and outcomes variables) from medical records and Health Outcomes (exacerbations, admissions). Variable response: Difference in exacerbations and admissions in 2 periods analysed. Bivariate and multivariate analysis. RESULTS: Mean age was 75 (+/-9.3), 63.7% males with a BMI of 29.4 (+/-7.1), and 21% active smokers. Mean FEV1, 48.2% (+/-18.7). Mean exacerbations in the first period, 2.86 (+/-2.29) and in the second 1.36 (+/-1.56) (P<.001). Mean hospital admissions in the first and second period, 0.56 (+/-0.94) and 0.31 (+/-0.66) (P<.001), respectively. The decrease in the number of exacerbations was directly associated with having >=2 exacerbations in the first period, reviewed in Primary Care, and inversely with heart failure and with having >=2 exacerbations in the second period (R2=0.28; P<.001) CONCLUSIONS: The number of exacerbations and admissions decreased significantly in both periods assessed. However, the evaluated process indicators did not improve. Prospective intervention studies are necessary to establish the possible causal relationship.

PMID- 27692654 TI - The Prevalence and Specificity of Depression Diagnosis in a Clinic-Based Population of Adults With Type 2 Diabetes Mellitus. AB - OBJECTIVE: To estimate the crude prevalence of minor depressive disorder (MinD) in a clinic-based population of adults with type 2 diabetes. METHODS: We screened a clinical sample of 702 adults with type 2 diabetes for depressive symptoms using the Patient Health Questionnaire-2 and performed a structured diagnostic psychiatric interview on 52 screen-positive and a convenience sample of 51 screen negative individuals. Depressive disorder diagnoses were made using Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) Text Revised criteria and categorized as MinD, major depressive disorder (MDD), or no depressive disorder. We estimated prevalence of MinD and MDD and derived 95% CIs. RESULTS: The crude prevalence of current, past, and current or past MinD was 4.3% (95% CI: 0.9 9.2%), 9.6% (95% CI: 3.9-15.9%), and 13.9% (95% CI: 7.7-21.2%), respectively. The crude prevalence of current, past, and current or past MDD was slightly higher 5.0% (95% CI: 1.9-9.4%), 12.0% (95% CI: 6.1-19.5%), and 17.0% (95% CI: 10.1 24.8%), respectively. There was a high prevalence of coexisting anxiety disorders in individuals with MinD (42.2%) and MDD (8.1%). Hemoglobin A1c levels were not significantly different in individuals with MinD or MDD compared to those without a depressive disorder. CONCLUSIONS: MinD is comparably prevalent to MDD in patients with type 2 diabetes; both disorders are associated with concomitant anxiety disorders. MinD is not included in the DSM-5; however, our data support continuing to examine patients with chronic medical conditions for MinD. PMID- 27692656 TI - Preparticipation Cardiac Screening in Young Athletes: In Search of the Golden Chalice. PMID- 27692657 TI - Detecting Underlying Cardiovascular Disease in Young Competitive Athletes. AB - BACKGROUND: Sudden cardiac death (SCD) is frequently the first manifestation of underlying cardiovascular disease in young competitive athletes (YCAs), yet there are no Canadian guidelines for preparticipation screening in this population. The goal of this study was to determine the prevalence of potentially lethal cardiovascular disease in a sample of Canadian YCAs by comparing 2 screening strategies. METHODS: We prospectively screened 1419 YCAs in British Columbia, Canada (age 12-35 years). We initially screened 714 YCAs using the American Heart Association 12-element recommendations, physical examination, and electrocardiogram (ECG) examination (phase 1). This strategy yielded a high number of false positive results; 705 YCAs were subsequently screened using a novel SportsCardiologyBC (SCBC) questionnaire and ECG examination in the absence of a physical examination (phase 2). RESULTS: Overall, 7 YCAs (0.52%) were found to have clinically significant diagnoses associated with SCD (4 pre-excitation, 1 long QT syndrome, 1 mitral valve prolapse, 1 hypertrophic cardiomyopathy). Six of the 7 athletes (85.7%) with disease possessed an abnormal ECG. Conversely, only 2 had a positive personal or family history (1 athlete had an abnormal ECG and family history). The SCBC questionnaire and protocol (phase 2) was associated with fewer false positive screens; 3.7% (25 of 679) compared with 8.1% (55 of 680) in phase 1 (P = 0.0012). CONCLUSIONS: The prevalence of conditions associated with SCD in a cohort of Canadian YCAs was comparable with American and European populations. The SCBC questionnaire and protocol were associated with fewer false positive screens. The ECG identified most of the positive cases irrespective of screening strategy used. PMID- 27692659 TI - Postoperative assessment of left ventricular function by two-dimensional strain (speckle tracking) after paediatric cardiac surgery. AB - BACKGROUND: Left ventricular (LV) dysfunction may complicate paediatric cardiac surgery with cardiopulmonary bypass, notably after long aortic cross-clamping (ACC). Assessment of occult myocardial injury by conventional echocardiographic variables may be difficult in the postoperative period. AIMS: To evaluate the feasibility of two-dimensional (2D) strain in the postoperative period, and to assess the effect of ACC duration on this variable. METHODS: Thirty-three paediatric patients (age<18years) with congenital heart disease undergoing cardiac surgery with cardiopulmonary bypass were included in this prospective single-centre study. Daily echocardiography was performed from the day before surgery to the fifth postoperative day. LV ejection fraction and LV 2D strain were measured. The cohort was divided into three groups according to ACC duration (group 1:<30minutes; group 2: 30-80minutes; group 3:>80minutes). RESULTS: Mean age and weight were 4.2+/-2.5years and 15.1+/-5.2kg, respectively. Feasibilities of longitudinal, circumferential and radial strains were good, and quite similar to conventional variables. Compared with conventional variables, intra- and interobserver agreements regarding 2D strain were better (r=0.916, P<0.001 and r=0.855, P<0.001 for longitudinal strain versus r=0.156, P=0.54 and r=0.064, P=0.80 for LV ejection fraction by Simpson's method). Postoperative evolution of longitudinal and circumferential strains was significantly different between the three groups (P<0.001), whereas there was no difference using conventional variables. CONCLUSION: Postoperative LV 2D strain is a feasible and reproducible method. Strain measurements seem to indicate correlation with ACC duration. PMID- 27692658 TI - Localization of gaps during redo ablations of paroxysmal atrial fibrillation: Preferential patterns depending on the choice of cryoballoon ablation or radiofrequency ablation for the initial procedure. AB - BACKGROUND: Pulmonary vein (PV) isolation, using cryoballoon or radiofrequency ablation, is the cornerstone therapy for symptomatic paroxysmal atrial fibrillation (AF) refractory to antiarrhythmic drugs. One-third of the patients have recurrences, mainly due to PV reconnections. AIMS: To describe the different locations of reconnection sites in patients who had previously undergone radiofrequency or cryoballoon ablation, and to compare the characteristics of the redo procedures in both instances. METHODS: Demographic data and characteristics of the initial ablation (cryoballoon or radiofrequency) were collected. Number and localization of reconduction gaps, and redo characteristics were reviewed. RESULTS: Seventy-four patients scheduled for a redo ablation of paroxysmal AF were included; 38 had been treated by radiofrequency ablation and 36 by cryoballoon ablation during the first procedure. For the initial ablation, procedural and fluoroscopy times were significantly shorter for cryoballoon ablation (147.8+/-52.6min vs. 226.6+/-64.3min [P<0.001] and 37.0+/-17.7min vs. 50.8+/-22.7min [P=0.005], respectively). Overall, an identical number of gaps was found during redo procedures of cryoballoon and radiofrequency ablations. However, a significantly higher number of gaps were located in the right superior PV for patients first ablated with radiofrequency (0.9+/-1.0 vs. 0.5+/-0.9; P=0.009). Gap localization displayed different patterns. Although not significant, redo procedures of cryoballoon ablation were slightly shorter and needed shorter durations of radiofrequency to achieve PV isolation. CONCLUSIONS: During redo procedures, gap localization pattern is different for patients first ablated with cryoballoon or radiofrequency ablation, and right superior PV reconnections occur more frequently after radiofrequency ablation. Redo ablation of a previous cryoballoon ablation appears to be easier. PMID- 27692660 TI - Therapeutic hypothermia to protect the heart against acute myocardial infarction. AB - The cardioprotective effect of therapeutic hypothermia (32-34 degrees C) has been well demonstrated in animal models of acute myocardial infarction. Beyond infarct size reduction, this protection was associated with prevention of the no-reflow phenomenon and long-term improvement in terms of left ventricular remodelling and performance. However, all these events were observed when hypothermia was induced during the ischaemic episode, and most benefits virtually vanished after reperfusion. This is consistent with clinical findings showing a lack of benefit from hypothermia in patients presenting acute myocardial infarction in most trials. In these studies, hypothermia was most often achieved too far into the reperfusion phase (i.e. possibly too late to reduce infarct size); this is supported by meta-analyses and subgroup analyses suggesting that the benefits of hypothermia could still be observed in patients with a large infarction and more rapid cooling before reperfusion. Novel strategies for ultra-fast induction of hypothermia and/or prehospital cooling might therefore be more beneficial. PMID- 27692661 TI - Usefulness of 3-Tesla cardiac magnetic resonance imaging in the assessment of aortic stenosis severity in routine clinical practice. AB - BACKGROUND: Recently, 1.5-Tesla cardiac magnetic resonance imaging (CMR) was reported to provide a reliable alternative to transthoracic echocardiography (TTE) for the quantification of aortic stenosis (AS) severity. Few data are available using higher magnetic field strength MRI systems in this context. AIMS: To evaluate the feasibility and reproducibility of the assessment of aortic valve area (AVA) using 3-Tesla CMR in routine clinical practice, and to assess concordance between TTE and CMR for the estimation of AS severity. METHODS: Ninety-one consecutive patients (60 men; mean age 74+/-10years) with known AS documented by TTE were included prospectively in the study. RESULTS: All patients underwent comprehensive TTE and CMR examination, including AVA estimation using the TTE continuity equation (0.81+/-0.18cm2), direct CMR planimetry (CMRp) (0.90+/-0.22cm2) and CMR using Hakki's formula (CMRhk), a simplified Gorlin formula (0.70+/-0.19cm2). Although significant agreement with TTE was found for CMRp (r=0.72) and CMRhk (r=0.66), CMRp slightly overestimated (bias=0.11+/ 0.18cm2) and CMRhk slightly underestimated (bias=-0.11+/-0.17cm2) AVA compared with TTE. Inter- and intraobserver reproducibilities of CMR measurements were excellent (r=0.72 and r=0.74 for CMRp and r=0.88 and r=0.92 for peak aortic velocity, respectively). CONCLUSION: 3-Tesla CMR is a feasible, radiation-free, reproducible imaging modality for the estimation of severity of AS in routine practice, knowing that CMRp tends to overestimate AVA and CMRhk to underestimate AVA compared with TTE. PMID- 27692662 TI - Place of non-vitamin K antagonist oral anticoagulants in anticoagulant antiplatelet combinations in peripheral artery disease. AB - Non-vitamin K antagonist oral anticoagulants are becoming increasingly important in the prophylaxis and treatment of thrombosis in atrial fibrillation and venous thromboembolism. Antiplatelets are widely prescribed in the primary and secondary prevention of cardiac and vascular diseases. There are potentially numerous situations where anticoagulants and antiplatelets may be combined; these combinations have been explored in coronary artery disease, and some have been included in updated recommendations. Is it legitimate to transpose these recommendations to the management of peripheral artery disease? The specific characteristics of the treated vessels, the stents used, the respective frequencies of stent thrombosis and its effect on the target organ are probably different, and explain why opinions differ. However, because of a lack of evidence, empirical behaviours are being established without scientific validation. This review of the literature details the situations in which combinations of an anticoagulant and an antiplatelet have been explored in peripheral artery disease. We discuss the issue of antithrombotic combinations in stable peripheral artery disease and for vascular or endovascular surgery. PMID- 27692663 TI - Decisions by Default: Incomplete and Contradictory MOLST in Emergency Care. AB - OBJECTIVES: What patients intend when they make health care choices and whether they understand the meaning of orders for life-sustaining treatment forms is not well understood. The purpose of this study was to analyze the directives from a sample of emergency department (ED) patients' MOLST forms. PROCEDURES: MOLST forms that accompanied 100 patients who were transported to an ED were collected and their contents analyzed. Data categories included age, gender, if the patient completed the form for themselves, medical orders for life-sustaining treatment including intubation, ventilation, artificial nutrition, artificial fluids or other treatment, and wishes for future hospitalization or transfer. Frequencies of variables were calculated and the associations between them were determined using chi-square. An a priori list of combinations of medical orders that were contradictory was developed. Contradictions with Orders for CPR (cardiopulmonary resuscitation) included the choice of one or more of the following: Comfort care; Limited intervention; Do Not Intubate; No rehospitalization; No IV (intravenous) fluids; and No antibiotics. Contradictions with DNR orders included the choice of one or more of the following: Intubation; No limitation on interventions. Contradictions with orders for Comfort Care were as follows: Send to the hospital; Trial period of IV fluids; Antibiotics. The frequencies of coexisting but contradictory medical orders were calculated using crosstabs. Free text responses to the "other instructions" section were submitted to content analysis. RESULTS: Sixty-nine percent of forms reviewed had at least one section left blank. Inconsistencies were found in patient wishes among a subset (14%) of patients, wherein their desire for "comfort measures only" seemed contradicted by a desire to be sent to the hospital, receive IV fluids, and/or receive antibiotics. CONCLUSIONS: Patients and proxies may believe that making choices and documenting some, but not all, of their wishes on the MOLST form is sufficient for directing their end-of-life care. The result of making some, but not all, choices may result in patients receiving undesired, extraordinary, or invasive care. PMID- 27692664 TI - Quality standards versus nutritional taxes: Health and welfare impacts with strategic firms. AB - The goal of this paper is to better understand firms' strategic reactions to nutritional policies targeting food quality improvements and to derive optimal policies. We propose a model of product differentiation, taking into account the taste and health characteristics of products. We study how two firms react to alternative policies: an MQS policy, linear taxation of the two goods on the market, and taxation of the low-quality good. The MQS and the taxation of the low quality product are the preferred options by a social planner. If taste is moderately important, the MQS policy is chosen by a populist and a paternalist social planner. If taste is a major component of choice, the populist planner chooses to tax the low-quality product whereas the paternalist planner prefers the MQS policy. Finally, for a paternalist social planner, an MQS-based policy always allows for higher levels of welfare than an information policy alone. PMID- 27692665 TI - SPCA2 couples Ca2+ influx via Orai1 to Ca2+ uptake into the Golgi/secretory pathway. AB - Dysregulation of the Golgi/Secretory Pathway Ca2+ transport ATPase SPCA2 is implicated in breast cancer. During lactation and in luminal breast cancer types, SPCA2 interacts with the plasma membrane Ca2+ channel Orai1, promoting constitutive Ca2+ influx, which is termed store independent Ca2+ entry (SICE). The mechanism of SPCA2/Orai1 interaction depends on the N- and C-termini of SPCA2. These extensions may play a dual role in activating not only Orai1, but also Ca2+ transport into the Golgi/secretory pathway, which we tested by investigating the impact of various SPCA2 N- and/or C-terminal truncations on SICE and Ca2+ transport activity of SPCA2. C-terminal truncations impair SICE and SPCA2 activity, but also affect targeting, whereas N-terminal truncations affect targeting and inactivate SPCA2, but remarkably, SICE activation remains unaffected. Importantly, overexpression of SPCA2 increases the Ca2+ content of non-ER stores, which depends on Orai1 and SPCA2 activity. Thus, Orai1-mediated Ca2+-influx and SPCA2-mediated Ca2+ uptake activity into the Golgi/secretory pathway might be coupled possibly in a microdomain. This channel/pump complex may efficiently transfer Ca2+ into the secretory pathway, which might play a role in SPCA2-expressing secretory cells, such as mammary gland during lactation. PMID- 27692666 TI - Experiences and needs of parents of critically injured children during the acute hospital phase: A qualitative investigation. AB - INTRODUCTION: Physical injury is a leading cause of death and disability among children worldwide and the largest cause of paediatric hospital admission. Parents of critically injured children are at increased risk of developing mental and emotional distress in the aftermath of child injury. In the Australian context, there is limited evidence on parent experiences of child injury and hospitalisation, and minimal understanding of their support needs. The aim of this investigation was to explore parents' experiences of having a critically injured child during the acute hospitalisation phase of injury, and to determine their support needs during this time. METHODS: This multi-centre study forms part of a larger longitudinal mixed methods study investigating the experiences, unmet needs and well-being of parents of critically injured children over the two-year period following injury. This paper describes parents' experiences of having a child 0-13 years hospitalised with critical injury in one of four Australian paediatric hospitals. Semi-structured interviews were conducted with forty parents and transcribed verbatim. The data were managed using NVIVO 10 software and thematically analysed. FINDINGS: Forty parents (26 mothers and 14 fathers) of 30 children (14 girls and 16 boys aged 1-13 years) from three Australian States participated. The majority of children were Australian born. Three main themes with sub-themes were identified: navigating the crisis of child injury; coming to terms with the complexity of child injury; and finding ways to meet the family's needs. CONCLUSIONS: There is a need for targeted psychological care provision for parents of critically injured children in the acute hospital phase, including psychological first aid and addressing parental blame attribution. Parents and children would benefit from the implementation of anticipatory guidance frameworks informed by a family-centred social ecological approach to prepare them for the trauma journey and for discharge. This approach could inform care delivery throughout the child injury recovery trajectory. The development and implementation of a major trauma family support coordinator in paediatric trauma centres would make a tangible difference to the care of critically injured children and their families.

AB - The aim of this study was to examine the kinetics of the different mechanisms (radical pathway, photolysis, molecular reaction with H2O2 and reaction with ultrasonically generated oxidative species) involved in the homogeneous sono photoFenton (US/UV/H2O2/Fe) mineralization of antipyrine present in a synthetic municipal wastewater effluent (ASMWE). The dynamic behavior of hydroxyl (HO) radical generation and consumption in mineralization reaction under different systems was investigated by measuring hydroxyl radical concentration during the reaction. The overall mineralization process was optimized using a Central Composite Experimental Design (CCED) with four variables (initial concentrations of H2O2 and Fe(II), amplitude and pulse length). The response functions (pseudo first order mineralization kinetic rate constants) were fitted using neural networks (NNs). Under the optimal conditions ([H2O2]o=500mgL-1, [Fe(II)]o=27mgL 1, Amplitude (%)=20andPulse length=1), the TOC removal was 79% in 50min. The radical reaction in the bulk solution was found be the primary mineralization pathway (94.8%), followed by photolysis (3.65%), direct reaction with H2O2 (0.86%), and reaction by ultrasonically generated oxidative species (0.64%). The role of the Fe catalyst on the radical reaction and the presence of refractory intermediates towards hydroxyl radical were also studied. PMID- 27692668 TI - Intraperitoneal chemotherapy after interval debulking surgery for advanced-stage ovarian cancer: Feasibility and outcomes at a comprehensive cancer center. AB - OBJECTIVES: Intraperitoneal (IP)-based chemotherapy following primary debulking surgery (PDS), although associated with substantial toxicity, is supported by a strong evidence base. We sought to determine feasibility and outcomes of IP chemotherapy after interval debulking surgery (IDS) among patients deemed ineligible for PDS. METHODS: We identified all patients with high-grade, stage III/IV ovarian cancer treated at our institution with neoadjuvant chemotherapy (NACT) followed by IDS and postoperative chemotherapy from 1/2008-5/2013. IP and intravenous (IV) regimens were defined; demographic and clinical data were analyzed using appropriate statistics. RESULTS: Of 128 evaluable patients, 118 (92%) achieved <=1cm residual disease at IDS and 74 (58%) achieved a complete gross resection (CGR). An IP port was placed in 54/128 patients (42%), with 89% port utilization. Forty-eight (38%) of 128 patients received IP chemotherapy, 17 (13%) weekly IV paclitaxel/q3week carboplatin, and 63 (49%) q3week IV carboplatin/paclitaxel. Patients completed a median of 3 IP cycles (range, 2-6), with 3 (5.5%) of 54 ports removed due to complications. Overall survival (OS) for patients with a CGR treated with IP and weekly IV chemotherapy was 53.2months (range, 24.7-NE), and 44.2months (range, 30.2-NE) with any visible residual disease (p<0.001). Median OS was 53.2months (range, 44.5-NE) for IP-, not reached for weekly IV-, and 34.2months (range, 27.5-49.8) for q3week IV-treated patients (p=0.1). CONCLUSIONS: Patients administered IP after IDS had a high rate of successful port utilization, with few regimen switches. Oncologic outcomes were optimal in patients with a CGR at IDS, regardless of chemotherapy used. PMID- 27692670 TI - Strategies to broaden the cross-protective efficacy of vaccines against porcine reproductive and respiratory syndrome virus. AB - Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most economically important viral pathogens currently affecting swine production worldwide. Although PRRS vaccines have been commercially available for over 20 years, the available vaccines are considered inadequately effective for control and eradication of the virus. Major obstacles for the development of a highly effective PRRS vaccine include the highly variable nature of the viral genome, the viral ability to subvert the host immune system, and the incomplete understanding of the immune protection against PRRSV infection. This article summarizes the impediments for the development of a highly protective PRRS vaccine and reviews the vaccinology approaches that have been attempted to overcome one of the most formidable challenges, which is the substantial genetic variation among PRRSV isolates, to broaden the antigenic coverage of PRRS vaccines. PMID- 27692669 TI - Disease extent at secondary cytoreductive surgery is predictive of progression free and overall survival in advanced stage ovarian cancer: An NRG Oncology/Gynecologic Oncology Group study. AB - PURPOSE: GOG 152 was a randomized trial of secondary cytoreductive surgery (SCS) in patients with suboptimal residual disease (residual tumor nodule >1cm in greatest diameter) following primary cytoreductive surgery for advanced stage ovarian cancer. The current analysis was undertaken to evaluate the impact of disease findings at SCS on progression-free survival (PFS) and overall survival (OS). METHODS: Among the 550 patients enrolled on GOG-152, two-hundred-sixteen patients were randomly assigned following 3cycles of cisplatin and paclitaxel to receive SCS. In 15 patients (7%) surgery was declined or contraindicated. In the remaining 201 patients the operative and pathology reports were utilized to classify their disease status at the beginning of SCS as; no gross disease/microscopically negative N=40 (19.9%), no gross disease/microscopically positive N=8 (4.0%), and gross disease N=153 (76.1%). RESULTS: The median PFS for patients with no gross disease/microscopically negative was 16.1months, no gross disease/microscopically positive was 13.5months and for gross disease was 11.7months, P=0.002. The median OS for patients with no gross disease/microscopically negative was 51.5months, no gross disease/microscopically positive was 42.6months and for gross disease was 34.9months, P=0.018. CONCLUSION: Although as previously reported SCS did not change PFS or OS, for those who underwent the procedure, their operative and pathologic findings were predictive of PFS and OS. Surgical/pathological residual disease is a biomarker of response to chemotherapy and predictive of PFS and OS. PMID- 27692671 TI - Increasing compliance with the World Health Organization Surgical Safety Checklist-A regional health system's experience. AB - BACKGROUND: In 2009, NorthShore University HealthSystem adapted the World Health Organization Surgical Safety Checklist (SSC) at each of its 4 hospitals. Despite evidence that SSC reduces intraoperative mistakes and increase patient safety, compliance was found to be low with the paper form. In November 2013, NorthShore integrated the SSC into the electronic health record (EHR). The aim was to increase communication between operating room (OR) personnel and to encourage best practices during the natural workflow of surgeons, anesthesiologists, and nurses. The purpose of this study was to examine the impact of an electronic SSC on compliance and patient safety. METHODS: An anonymous OR observer selected cases at random and evaluated the compliance rate before the rollout of the electronic SSC. In June 2014, an electronic audit was performed to assess the compliance rate. Random OR observations were also performed throughout the summer in 2014. Perioperative risk events, such as consent issues, incorrect counts, wrong site, and wrong procedure were compared before and after the electronic SSC rollout. A perception survey was also administered to NorthShore OR personnel. RESULTS: Compliance increased from 48% (n = 167) to 92% (n = 1,037; P < .001) after the SSC was integrated into the electronic health record. Surgeons (91% vs 97%; P < .001), anesthesiologists (89% vs 100%; P < .001), and nurses (55% vs 93%; P < .001) demonstrated an increase in compliance. A comparison between risk events in the pre- and post-rollout period showed a 32% decrease (P < .01). Hospital-wide indicators including length of stay and 30-day readmissions were lower. In a survey to assess the OR personnel's perceptions of the new checklist, 76% of surgeons, 86% of anesthesiologists, and 88% of nurses believed the electronic SSC will have a positive impact on patient safety. CONCLUSIONS: The World Health Organization SSC is a validated tool to increase patient safety and reduce intraoperative complications. The electronic SSC has demonstrated an increased compliance rate, a reduced number of risk events, and most OR personnel believe it will have a positive impact on patient safety. PMID- 27692673 TI - Percutaneous thermal ablation of primary lung cancer. AB - Percutaneous ablation of small-size non-small-cell lung cancer (NSCLC) has demonstrated feasibility and safety in nonsurgical candidates. Radiofrequency ablation (RFA), the most commonly used technique, has an 80-90% reported rate of complete ablation, with the best results obtained in tumors less than 2-3cm in diameter. The highest one-, three-, and five-year overall survival rates reported in NSCLC following RFA are 97.7%, 72.9%, and 55.7% respectively. Tumor size, tumor stage, and underlying comorbidities are the main predictors of survival. Other ablation techniques such as microwave or cryoablation may help overcome the limitations of RFA in the future, particularly for large tumors or those close to large vessels. Stereotactic ablative radiotherapy (SABR) has its own complications and carries the risk of fiducial placement requiring multiple lung punctures. SABR has also demonstrated significant efficacy in treating small-size lung tumors and should be compared to percutaneous ablation. PMID- 27692672 TI - Road traffic noise, blood pressure and heart rate: Pooled analyses of harmonized data from 88,336 participants. AB - INTRODUCTION: Exposure to road traffic noise may increase blood pressure and heart rate. It is unclear to what extent exposure to air pollution may influence this relationship. We investigated associations between noise, blood pressure and heart rate, with harmonized data from three European cohorts, while taking into account exposure to air pollution. METHODS: Road traffic noise exposure was assessed using a European noise model based on the Common Noise Assessment Methods in Europe framework (CNOSSOS-EU). Exposure to air pollution was estimated using a European-wide land use regression model. Blood pressure and heart rate were obtained by trained clinical professionals. Pooled cross-sectional analyses of harmonized data were conducted at the individual level and with random-effects meta-analyses. RESULTS: We analyzed data from 88,336 participants, across the three participating cohorts (mean age 47.0 (+/-13.9) years). Each 10dB(A) increase in noise was associated with a 0.93 (95% CI 0.76;1.11) bpm increase in heart rate, but with a decrease in blood pressure of 0.01 (95% CI -0.24;0.23) mmHg for systolic and 0.38 (95% CI -0.53; -0.24) mmHg for diastolic blood pressure. Adjustments for PM10 or NO2 attenuated the associations, but remained significant for DBP and HR. Results for BP differed by cohort, with negative associations with noise in LifeLines, no significant associations in EPIC-Oxford, and positive associations with noise >60dB(A) in HUNT3. CONCLUSIONS: Our study suggests that road traffic noise may be related to increased heart rate. No consistent evidence for a relation between noise and blood pressure was found. PMID- 27692674 TI - Evaluation of tumor response to intra-arterial chemoembolization of hepatocellular carcinoma: Comparison of contrast-enhanced ultrasound with multiphase computed tomography. AB - PURPOSE: To compare the diagnostic accuracy of contrast-enhanced ultrasound (CEUS) with that of multiphase computed tomography (CT) in the evaluation of tumor response to transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC). MATERIAL AND METHODS: Fifty patients (41 men, 9 women; mean age, 53 years+/-12.5 [SD]) with a total of 70 HCCs (mean size, 5cm+/-3 [SD]) were evaluated. Post-TACE therapeutic assessment of HCC was done at 4 weeks. Patients with TACE done earlier and reporting with suspicion for recurrence were also included. Patients with hepatic masses seen on ultrasound were enrolled and subjected to CEUS, multiphase CT and magnetic resonance imaging (MRI). Hyperenhancing area at the tumor site on arterial phase of CEUS/multiphase CT/MRI was termed as residual disease (RD), the patterns of which were described on CEUS. Diagnostic accuracies of CEUS and MPCT were compared to that of MRI that was used as the reference standard. RESULTS: CEUS detected RD in 43/70 HCCs (61%). RD had a heterogeneous pattern in 22/43 HCCs (51%). Sensitivities of CEUS and multiphase CT were 94% (34/36; 95% CI: 81-99%) and 50% (18/36; 95% CI: 33 67%) respectively. Significant difference in sensitivity was found between CEUS and multiphase CT (P=0.0001). CEUS and multiphase CT had 100% specificity (95% CI: 83-100%). CONCLUSION: CEUS is a useful technique for detecting RD in HCC after TACE. For long term surveillance, CEUS should be complemented with multiphase CT/MRI for a comprehensive evaluation. PMID- 27692675 TI - Radiological evaluation of response to neoadjuvant treatment in pancreatic cancer. AB - Neoadjuvant chemotherapy has become common practice in the management of patients with non-metastatic pancreatic adenocarcinoma. This strategy helps better select patients who would benefit from surgical resection and also increase the number of patients amenable to surgical resection whose tumor seemed too locally advanced on initial imaging. However, several studies have shown that the radiological evaluation of the response after neoadjuvant therapy is difficult for pancreatic carcinoma. This article reviews the scientific basis of neoadjuvant therapy for non-metastatic pancreatic cancer and provides an update on tumor response evaluation with imaging after neoadjuvant treatment. PMID- 27692676 TI - Sudden death and cardiac arrest without phenotype: the utility of genetic testing. AB - Approximately 4% of sudden cardiac deaths are unexplained [the sudden arrhythmic death syndrome (SADS)], and up to 6-10% of survivors of cardiac arrest do not have an identifiable cardiac abnormality after comprehensive clinical evaluation [idiopathic ventricular fibrillation (IVF)]. Genetic testing may be able to play a role in diagnostics and can be targeted to an underlying phenotype present in family members following clinical evaluation. Alternatively, post-mortem genetic testing (the "molecular autopsy") may diagnose the underlying cause if a clearly pathogenic rare variant is found. Limitations include a modest yield, and the high probability of finding a variant of unknown significance (VUS) leading to a low signal-to-noise ratio. Next generation sequencing enables cost-efficient high throughput screening of a larger number of genes but at the expense of increased genetic noise. The yield from genetic testing is even lower in IVF in the absence of any suggestion of another phenotype in the index case or his/her family, and should be actively discouraged at this time. Future improvements in diagnostic utility include optimization of the use of variant-calling pipelines and shared databases as well as patient-specific models of disease to more accurately assign pathogenicity of variants. Studying "trios" of parents and the index case may better assess the yield of sporadic and recessive disease. PMID- 27692677 TI - Continuity in the midst of change! PMID- 27692678 TI - [Reliability of a chronic obstructive pulmonary disease diagnosis register in Primary Care]. AB - INTRODUCTION/OBJECTIVE: One of main limitations in studies of COPD in health databases could be the low quality of the information. Our first aim was evaluate reliability of the registry of COPD diagnosis register in Primary Care. A description and comparison is also presented of the characteristics of the patients according to the diagnostic confirmation. MATERIAL AND METHODS: A cross sectional study using healthcare databases of Cantabria. A pre-selected sample of 1,457 patients was obtained in which COPD diagnosis was specifically registered. COPD confirmation was classified into confirmed COPD, not confirmed-not rejected COPD, and diagnostic error (over-diagnosis). Descriptive and clinical characteristics, comorbidities, and treatments were collected in each group. RESULTS: COPD was confirmed in 766 patients: 52.6% (95%CI: 49.9-55.2). Prevalence of over-diagnosis was 7.2% (95%CI: 5.9-8.6). There were statistically significant gender differences. In the COPD confirmed group age, tobacco consumption and severity according to FEV1 was higher. An average of 1.95 bronchial exacerbations during the last 4years was observed among diagnostic errors. Inhaled corticosteroids were prescribed in 74.9% of COPD confirmed patients, and in 41.9% of over-diagnosed patients. CONCLUSIONS: The reliability of the COPD register was deficient, with only 52.6% with a confirmed diagnosis. Stable treatment for COPD was prescribed in all groups, highlighting the use of inhaled corticosteroids. PMID- 27692679 TI - Scale-up of the electrokinetic fence technology for the removal of pesticides. Part II: Does size matter for removal of herbicides? AB - This work reports results of the application of electrokinetic fence technology in a 32 m3 -prototype which contains soil polluted with 2,4-D and oxyfluorfen, focusing on the evaluation of the mechanisms that describe the removal of these two herbicides and comparing results to those obtained in smaller plants: a pilot scale mockup (175 L) and a lab-scale soil column (1 L). Results show that electric heating of soil (coupled with the increase in the volatility) is the key to explain the removal of pollutants in the largest scale facility while electrokinetic transport processes are the primary mechanisms that explain the removal of herbicides in the lab-scale plant. 2-D and 3-D maps of the temperature and pollutant concentrations are used in the discussion of results trying to give light about the mechanisms and about how the size of the setup can lead to different conclusions, despite the same processes are occurring in the soil. PMID- 27692680 TI - Scale-up of the electrokinetic fence technology for the removal of pesticides. Part I: Some notes about the transport of inorganic species. AB - This work describes the application electrokinetic fence technology to a soil polluted with herbicides in a large prototype containing 32 m3 of soil. It compares performance in this large facility with results previously obtained in a pilot-scale mockup (175 L) and with results obtained in a lab-scale soil column (1 L), all of them operated under the same driving force: an electric field of 1.0 V cm-1. Within this wide context, this work focuses on the effect on inorganic species contained in soil and describes the main processes occurring in the prototype facility, as well as the differences observed respect to the lower scale plants. Thus, despite the same processes can be described in the three plants, important differences are observed in the evolution of the current intensity, moisture and conductivity. They can be related to the less important electroosmotic fluxes in the larger facilities and to the very different distances between electrodes, which lead to very different distribution of species and even to a very different evolution of the resulting current intensity. 2-D maps of the main species at different relevant moments of the test are discussed and important information is drawn from them. Ions depletion from soil appears as a very important problem which should be prevented if the effect of natural bioremediation and/or phytoremediation on the removal or organics aims to be accounted. PMID- 27692681 TI - Infrequent cardiac manifestations of sarcoidosis. AB - Cardiac sarcoidosis (CS) is found in 2-7% of patients with systemic sarcoidosis (SS). Its diagnosis and treatment is challenging, notwithstanding the poor prognosis and treatment. Hereby, we present a case of systemic sarcoidosis with rare cardiac manifestations of severe mitral incompetence and large coronary aneurysm in a previously healthy woman. She underwent successful mitral valve replacement and coronary artery bypass surgery and was maintained on low dose glucocorticoid therapy. PMID- 27692682 TI - Mobile Communication Devices, Ambient Noise, and Acoustic Voice Measures. AB - OBJECTIVES: The ability to move with mobile communication devices (MCDs; ie, smartphones and tablet computers) may induce differences in microphone-to-mouth positioning and use in noise-packed environments, and thus influence reliability of acoustic voice measurements. This study investigated differences in various acoustic voice measures between six recording equipments in backgrounds with low and increasing noise levels. METHODS: One chain of continuous speech and sustained vowel from 50 subjects with voice disorders (all separated by silence intervals) was radiated and re-recorded in an anechoic chamber with five MCDs and one high-quality recording system. These recordings were acquired in one condition without ambient noise and in four conditions with increased ambient noise. A total of 10 acoustic voice markers were obtained in the program Praat. Differences between MCDs and noise condition were assessed with Friedman repeated measures test and posthoc Wilcoxon signed-rank tests, both for related samples, after Bonferroni correction. RESULTS: (1) Except median fundamental frequency and seven nonsignificant differences, MCD samples have significantly higher acoustic markers than clinical reference samples in minimal environmental noise. (2) Except median fundamental frequency, jitter local, and jitter rap, all acoustic measures on samples recorded with the reference system experienced significant influence from room noise levels. CONCLUSIONS: Fundamental frequency is resistant to recording system, environmental noise, and their combination. All other measures, however, were impacted by both recording system and noise condition, and especially by their combination, often already in the reference/baseline condition without added ambient noise. Caution is therefore warranted regarding implementation of MCDs as clinical recording tools, particularly when applied for treatment outcomes assessments.

PMID- 27692683 TI - The Effect of Combined Out-of-Hospital Hypotension and Hypoxia on Mortality in Major Traumatic Brain Injury. AB - STUDY OBJECTIVE: Survival is significantly reduced by either hypotension or hypoxia during the out-of-hospital management of major traumatic brain injury. However, only a handful of small studies have investigated the influence of the combination of both hypotension and hypoxia occurring together. In patients with major traumatic brain injury, we evaluate the associations between mortality and out-of-hospital hypotension and hypoxia separately and in combination. METHODS: All moderate or severe traumatic brain injury cases in the preimplementation cohort of the Excellence in Prehospital Injury Care study (a statewide, before/after, controlled study of the effect of implementing the out-of-hospital traumatic brain injury treatment guidelines) from January 1, 2007, to March 31, 2014, were evaluated (exclusions: <10 years, out-of-hospital oxygen saturation <=10%, and out-of-hospital systolic blood pressure <40 or >200 mm Hg). The relationship between mortality and hypotension (systolic blood pressure <90 mm Hg) or hypoxia (saturation <90%) was assessed with multivariable logistic regression, controlling for Injury Severity Score, head region severity, injury type (blunt versus penetrating), age, sex, race, ethnicity, payer, interhospital transfer, and trauma center. RESULTS: Among the 13,151 patients who met inclusion criteria (median age 45 years; 68.6% men), 11,545 (87.8%) had neither hypotension nor hypoxia, 604 (4.6%) had hypotension only, 790 (6.0%) had hypoxia only, and 212 (1.6%) had both hypotension and hypoxia. Mortality for the 4 study cohorts was 5.6%, 20.7%, 28.1%, and 43.9%, respectively. The crude and adjusted odds ratios for death within the cohorts, using the patients with neither hypotension nor hypoxia as the reference, were 4.4 and 2.5, 6.6 and 3.0, and 13.2 and 6.1, respectively. Evaluation for an interaction between hypotension and hypoxia revealed that the effects were additive on the log odds of death. CONCLUSION: In this statewide analysis of major traumatic brain injury, combined out-of-hospital hypotension and hypoxia were associated with significantly increased mortality. This effect on survival persisted even after controlling for multiple potential confounders. In fact, the adjusted odds of death for patients with both hypotension and hypoxia were more than 2 times greater than for those with either hypotension or hypoxia alone. These findings seem supportive of the emphasis on aggressive prevention and treatment of hypotension and hypoxia reflected in the current emergency medical services traumatic brain injury treatment guidelines but clearly reveal the need for further study to determine their influence on outcome.

Both environmental and genetic factors play important roles in PD etiology. A number of environmental toxins cause parkinsonism in human and animal models. Genetic studies of rare early onset familial PD cases resulted in identification of disease-linked mutations in multiple genes. Nevertheless, the potential interaction between environment and genetics in PD pathogenesis remains largely unknown. We hypothesized that environmental factors induce abnormal epigenetic regulation that is involved in the pathogenesis of both familial and sporadic PD. We determined the global methylation status of 80,000-110,000 CpG sites in each of the five sporadic PD patient brains and five age and postmodern interval matched control brains utilizing bisulfite padlock sequencing. Multiple genes involved in neurogenesis, particularly the ones in the Wnt signaling pathway, were hypermethylated in PD brains compared to their matched control brains. Consistent with the DNA methylation changes, marked reduction of protein expression was observed for four Wnt and neurogenesis related genes (FOXC1, NEURG2, SPRY1, and CTNNB1) in midbrain dopaminergic (DA) neurons of PD. The treatment of low concentration of 1-methyl-4-phenylpyridinium (MPP+) for cells resulted in downregulation of Wnt related genes. The study revealed an important link between the epigenetic disregulation of Wnt signaling and the pathogenesis and progression of PD. PMID- 27692693 TI - Clinical outcomes of anatomic, all-inside, anterior cruciate ligament (ACL) reconstruction. AB - BACKGROUND: This paper reports the outcomes of patients undergoing ACL reconstruction using a TransLateral single bundle, all-inside hamstring technique at a minimum of two year follow-up. METHODS: The semitendinosus alone is harvested, quadrupled and attached in series to two adjustable suspensory fixation devices. Femoral and tibial sockets are produced using a retrograde drill. The graft is deployed, fixed and tensioned on both tibia and femur. Patients were evaluated preoperatively using the KOOS, Lysholm and Tegner scores and at six, 12 and 24months postoperatively. Objective assessment of knee laxity was performed using the KT-1000 along with goniometric measurement of range or motion. RESULTS: One hundred and eight patients, mean age 30.9years (range 15 to 61) were included. Mean follow-up 49.8months (range 30-66). The mean increase in KOOS at two years was 30.3 points; Lysholm, 33.1 points; Tegner Activity scale, 2.0 levels. These were all statistically significant (p<0.001). Range of motion in the reconstructed knee approximated the uninjured knee by 12months and was restored by two years. KT-1000 showed significant reduction in side-side difference to no more than 2.4mm at all postoperative time points (p<0.001). Re rupture rate in this series was 6.5%, all following episodes of significant additional postoperative trauma to the knee. CONCLUSIONS: TransLateral all-inside ACL reconstruction demonstrates good medium term subjective and objective outcomes with a low complication and failure rate.

AB - INTRODUCTION: Neuromuscular blockade enables airway management, ventilation and surgical procedures. However there is no national consensus on its routine clinical use. The objective was to establish the degree of agreement among anaesthesiologists and general surgeons on the clinical use of neuromuscular blockade in order to make recommendations to improve its use during surgical procedures. METHODS: Multidisciplinary consensus study in Spain. Anaesthesiologists experts in neuromuscular blockade management (n=65) and general surgeons (n=36) were included. Delphi methodology was selected. A survey with 17 final questions developed by a dedicated scientific committee was designed. The experts answered the successive questions in two waves. The survey included questions on: type of surgery, type of patient, benefits/harm during and after surgery, impact of objective neuromuscular monitoring and use of reversal drugs, viability of a multidisciplinary and efficient approach to the whole surgical procedure, focussing on the level of neuromuscular blockade. RESULTS: Five recommendations were agreed: 1) deep neuromuscular blockade is very appropriate for abdominal surgery (degree of agreement 94.1%), 2) and in obese patients (76.2%); 3) deep neuromuscular blockade maintenance until end of surgery might be beneficial in terms of clinical aspects, such as as immobility or better surgical access (86.1 to 72.3%); 4) quantitative monitoring and reversal drugs availability is recommended (89.1%); finally 5) anaesthesiologists/surgeons joint protocols are recommended. CONCLUSIONS: Collaboration among anaesthesiologists and surgeons has enabled some general recommendations to be established on deep neuromuscular blockade use during abdominal surgery.

PMID- 27692696 TI - De Ritis Ratio (AST/ALT) as a Significant Prognostic Factor in Patients With Upper Tract Urothelial Cancer Treated With Surgery. AB - INTRODUCTION: We investigated the clinical prognostic value of preoperative De Ritis ratio (aspartate aminotransferase [AST]/alanine aminotransferase [ALT]) on postsurgical survival outcomes in patients with upper tract urothelial cancer (UTUC). PATIENTS AND METHODS: We retrospectively analyzed the data of 623 patients who underwent radical nephrouretectomy for UTUC. Multivariate regression tests were performed to identify possible associations between adverse pathologic events and AST/ALT. The risk of postoperative progression and survival were tested using Kaplan-Meier analyses and Cox proportional hazards models. RESULTS: According to the receiver operator characteristic curve of AST/ALT for cancer specific mortality, patients with AST/ALT value >=1.5 were regarded as the high AST/ALT group, and the remaining patients formed the low AST/ALT group. In Kaplan Meier analyses, the high AST/ALT group showed worse progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (all P < .001). Elevated AST/ALT was associated with higher T stage (hazard ratio [HR], 1.577; 95% confidence interval [CI], 1.077-2.311; P = .033) and higher cellular grade (HR, 1.538; 95% CI, 1.034-2.287; P = .041) in multivariate regression tests. In multivariate Cox analyses, high AST/ALT was revealed as an independent predictor of PFS (HR, 2.335; 95% CI, 1.633-3.340; P < .001), CSS (HR, 2.550; 1.689-3.851; P < .001), and overall survival (HR, 2.069; 95% CI, 1.409-3.038; P < .001). CONCLUSION: Elevated preoperative AST/ALT was a significant predictor of worse postoperative survival in patients surgically treated for UTUC. Further large prospective studies are needed for better understanding of the prognostic value of preoperative AST/ALT. PMID- 27692695 TI - Adjunctive 5-Hydroxytryptophan Slow-Release for Treatment-Resistant Depression: Clinical and Preclinical Rationale. AB - Serotonin transporter (SERT) inhibitors treat depression by elevating brain extracellular 5-hydroxytryptamine (5-HTExt). However, only one-third of patients respond adequately. Treatment-resistant depression (TRD) is a major unmet need. Interestingly, elevating 5-HTExt beyond what is achieved by a SERT inhibitor appears to treat TRD. Adjunctive administration of 5-hydroxytryptophan (5-HTP) safely elevates 5-HTExt beyond the SERT inhibitor effect in humans; however, 5 HTP cannot be a clinically viable drug because of its poor pharmacokinetics. A slow-release (SR) delivery mode would be predicted to overcome the pharmacokinetic limitations of 5-HTP, substantially enhancing the pharmacological action and transforming 5-HTP into a clinically viable drug. Animal studies bear out this prediction. Thus, adjunct 5-HTP SR could be an important new treatment for TRD. Here, we review the clinical and preclinical evidence for this treatment. PMID- 27692697 TI - Low-Dose Oral Ethinylestradiol With Concomitant Low-Dose Acetylsalicylic Acid for Advanced Castrate-Resistant Prostate Cancer. AB - BACKGROUND: The aim of the present study was to evaluate the activity and tolerability of low-dose oral ethinylestradiol (EE) and luteinizing hormone releasing hormone analogue with concomitant low-dose acetylsalicylic acid (ASA) as a thromboprophylactic agent for advanced castrate-resistant prostate cancer (CRPC). PATIENTS AND METHODS: The patients received an EE dose of 150 MUg daily (50 MUg 3 times daily) and an ASA dose of 100 mg once daily. The primary endpoint was the prostate-specific antigen response. RESULTS: A total of 32 patients were enrolled. A PSA response was observed in 19 patients (59.3%; 95% confidence interval [CI], 41%-76%). The median progression-free survival was 9.4 months (95% CI, 6.5-14.1 months). The treatment was generally well tolerated and no grade 3-4 toxicity was observed. Only 1 patient interrupted EE because of a cardiac event and 1 patient experienced grade 2 nausea and vomiting. No major bleeding occurred. CONCLUSION: Low-dose EE with concomitant low-dose ASA is safe, showing potential activity in patients with advanced CRPC, and should be investigated further.

AB - BACKGROUND: By conceptualizing domains of behavior transdiagnostically, the National Institute of Mental Health Research Domain Criteria (NIMH RDoC) initiative facilitates new ways of studying psychiatric symptoms. In this study, latent profile analysis (LPA) was used to empirically derive classes or patterns of psychiatric symptoms in youth that transect traditional nosologic boundaries. METHODS: Data were drawn from 509 children and adolescents (ages 7-18 years; mean age =12.9 years; 54% male) who were evaluated in the NIMH Emotion and Development Branch and were heterogeneous with respect to presenting diagnoses and symptoms. Youth and/or their parents completed measures of several core symptom dimensions: irritability, anxiety, depression, and attention deficit hyperactivity disorder (ADHD). LPA was used to parse response patterns into distinct classes, based on the levels of, and interrelations among, scores on the different measures. RESULTS: Five classes emerged: low levels of symptomatology (52% of sample); anxiety and mild depressive symptoms (17%); parent-reported irritability and ADHD (16%); irritability and mixed comorbid symptoms (10%); and high levels of irritability, anxiety, depression, and ADHD (5%). Importantly, these latent classes cut across informants and the clinical conditions for which youth were initially evaluated. Further, the classes characterized by irritability exhibited the poorest overall functioning. LIMITATIONS: These data were cross-sectional. Examination of external validators, including neurobiological correlates and symptom course, is warranted. CONCLUSIONS: Results inform our understanding of the structure of psychiatric symptoms in youth and suggest new ways to operationalize psychopathology and examine it in relation to neurobiology.

PMID- 27692702 TI - Pulmonary Artery Catheter Use During Cardiac Surgery in the United States. PMID- 27692703 TI - Targeted Bleeding Management Reduces the Requirements for Blood Component Therapy in Lung Transplant Recipients. AB - OBJECTIVE: Lung transplantation is associated with high rates of bleeding and frequent blood transfusion. The authors aimed to determine if point-of-care coagulation testing (POCCT) reduced transfusion requirements. DESIGN, SETTINGS, AND PARTICIPANTS: A before-and-after cohort analysis conducted at a single tertiary referral center. Ninety-three sequential adult patients between January 2010 and January 2014 undergoing isolated lung transplant without preoperative extracorporeal support were analyzed. INTERVENTION: ROTEM and multi-plate POCCT were introduced on July 1, 2012, with an associated algorithm based on the results. MEASUREMENTS AND MAIN RESULTS: Statistically significant decreases in the proportion of patients receiving PRBCs (87% v 65%; p = 0.015), FFP (72% v 30%; p<0.0001) and platelets (70% v 37%; p = 0.002) were found after the intervention. There were small decreases in median chest tube blood loss at 2 hours (300 mLs v 215 mLs; p = 0.03) and 4 hours (440 mLs v 350 mLs; p = 0.050) but not at 12 hours postoperatively. There were no changes in reoperation for bleeding (9% v 4%; p = 0.158) or in-hospital mortality (6% v 2%; p = 0.617). The cost of blood products administered decreased from a median of $3,935.00 to $991.00 (p<0.001). CONCLUSIONS: Use of POCCT in lung-transplant surgery is associated with significant reductions in blood product use and cost. There were no detectable changes in outcome aside from a small decrease in early postoperative bleeding. PMID- 27692704 TI - Sevoflurane and Isoflurane-Pharmacokinetics, Hemodynamic Stability, and Cardioprotective Effects During Cardiopulmonary Bypass. AB - OBJECTIVES: This study aimed to evaluate the pharmacokinetic profiles of sevoflurane and isoflurane during use of minimized extracorporeal circulation to perform coronary artery bypass graft surgery. Furthermore, cardiovascular stability during bypass and the postoperative release of troponins were evaluated. DESIGN: Prospective, randomized study. SETTING: University hospital. PARTICIPANTS: The study comprised 31 adult patients undergoing coronary artery bypass grafting. INTERVENTIONS: The pharmacokinetic measurements of the concentration of the volatile anesthetics in the arterial and venous blood, air inlet, air outlet, and gas exhaust of the extracorporeal circulation were recorded. Secondary end-points were cardiovascular stability during bypass, amount of postoperative release of troponin, time to extubation, time to discharge from the intensive care unit and the hospital, and 30-day mortality. MEASUREMENTS AND MAIN RESULTS: Thirty patients completed the protocol. The pharmacokinetics of isoflurane and sevoflurane were almost identical, with a rapid wash-in (time to reach 50% of arterial steady state) concentration of 0.87+/-0.97 minutes and 1.14+/-0.35 minutes for isoflurane and sevoflurane, respectively, and a biphasic venous elimination with a terminal half-life of approximately 10 minutes for both compounds. There was a correlation between the gas inlet and the gas exhaust of the extracorporeal circulation. No difference in cardiovascular stability was found. High-sensitivity troponin concentrations on the first postoperative morning were 0.355+/-0.312 ug/mL and 0.225+/-0.111 ug/mL in the isoflurane and sevoflurane groups, respectively (p = 0.147). CONCLUSIONS: The study found similar pharmacokinetics regarding wash-in and wash-out for sevoflurane and isoflurane. In addition, no difference in cardiovascular stability was found. The markers of cardiac damage were not different between the two anesthetics. Based on these data, sevoflurane and isoflurane might be used equivalently in patients undergoing coronary artery bypass graft surgery with extracorporeal circulation.

AB - OBJECTIVE: The aim of this in vitro study was to evaluate the effect of core ceramic grinding on the fracture behaviour of bilayered zirconia under two loading schemes. METHODS: Interfacial surfaces of sandblasted zirconia disks (A) were ground with 80 (B), 120 (C) and 220 (D) grit diamond discs, respectively. Surface roughness and topographic analysis were performed using a confocal scanning laser microscope (CSLM) and a scanning electron microscopy (SEM). Relative monoclinic content was evaluated using X-ray diffraction analysis (XRD) then reevaluated after simulated veneer firing. Biaxial fracture strength (sigma) and Weibull modulus (m) were calculated either with core in compression (subgroup Ac-Dc) or in tension (subgroup At-Dt). Facture surfaces were examined by SEM and energy dispersive X-ray spectroscopy (EDS). Maximum tensile stress at fracture was estimated by finite element analysis. Statistical data analysis was performed using Kruskal-Wallis and one-way ANOVA at a significance level of 0.05. RESULTS: As grit size of the diamond disc increased, zirconia surface roughness decreased (p<0.001). Thermal veneering treatment reversed the transformation of monoclinic phase observed after initial grinding. No difference in initial (p=0.519 for subgroups Ac-Dc) and final fracture strength (p=0.699 for subgroups Ac-Dc; p=0.328 for subgroups At-Dt) was found among the four groups for both loading schemes. While coarse grinding slightly increased final fracture strength reliability (m) for subgroups Ac-Dc. Two different modes of fracture were observed according to which material was on the bottom surface. Components of the liner porcelain remained on the zirconia surface after fracture for all groups. SIGNIFICANCE: Technician grinding changed surface topography of zirconia ceramic material, but was not detrimental to the bilayered system strength after veneer application. Coarse grinding slightly improved the fracture strength reliability of the bilayered system tested with core in compression. It is recommended that veneering porcelain be applied directly after routine lab grinding of zirconia ceramic, and its application on rough zirconia cores may be preferred to enhance bond strength. PMID- 27692708 TI - Characterization and comparison of the temporal dynamics of ruminal bacterial microbiota colonizing rice straw and alfalfa hay within ruminants. AB - Three ruminally cannulated Holstein cows were used to characterize the dynamics of bacterial colonization of rice straw and alfalfa hay and to assess the differences in the composition and inferred gene function of the colonized microbiota between these 2 forages. Nonincubated (0h) rice straw and alfalfa hay samples and residues in nylon bags incubated for 0.5, 2, 6, 16, and 48h were analyzed for dry matter and were used for DNA extraction and MiSeq (Illumina Inc., San Diego, CA) sequencing of the 16S rRNA gene. The microbial communities that colonized the air-dried and nonincubated (0h) rice straw and alfalfa hay were both dominated by members of the Proteobacteria (contributing toward 70.47% of the 16S RNA reads generated). In situ incubation of the 2 forages revealed major shifts in the community composition: Proteobacteria were replaced within 30min by members belonging to the Bacteroidetes and Firmicutes, contributing toward 51.9 and 36.6% of the 16S rRNA reads generated, respectively. A second significant shift was observed after 6h of rumen incubation, when members of the Spirochaetes and Fibrobacteria phyla became abundant in the forage-adherent community. During the first 30min of rumen incubation, ~20.7 and 36.1% of the rice straw and alfalfa hay, respectively, were degraded, whereas little biomass degradation occurred between 30min and 2h after the rice straw or alfalfa hay was placed in the rumen. Significant differences were noted in attached bacterial community structure between the 2 forage groups, and the abundances of dominant genera Anaeroplasma, Butyrivibrio, Fibrobacter, and Prevotella were affected by the forage types. Real-time PCR results showed that the 16S rRNA copies of total bacteria attached to these 2 forages were affected by the forage types and incubation time, and higher numbers of attached bacterial 16S rRNA were observed in the alfalfa hay samples than in the rice straw from 0.5 to 16h of incubation. The metagenomes predicted by phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) revealed that the forage types significantly affected 21 metabolic pathways identified in the Kyoto Encyclopedia of Genes and Genomes, and 33 were significantly changed over time. Collectively, our results reveal a difference in the dynamics of bacterial colonization and the inferred gene function of microbiota associated with rice straw and alfalfa hay within the rumen. These findings are of great importance for the targeted improvement of forage nutrient use efficiency in ruminants. PMID- 27692709 TI - Effect of a long-chain n-3 polyunsaturated fatty acid-enriched diet on adipose tissue lipid profiles and gene expression in Holstein dairy cows. AB - The objective of this study was to determine whether fish oil supplement has an effect on adipose tissue lipid profiles and gene expression in postpartum dairy cows. Holstein cows were supplemented with either long-chain n-3 polyunsaturated fatty acid (PUFA; protected fish oil) or control PUFA (n-6; toasted soybeans) for 2mo after calving (n=23 per diet). These cows showed no difference in milk production or metabolic parameters, but exhibited a tendency toward a decrease in early embryo mortality rate after artificial insemination. We hypothesized that, in addition to this effect, modifications in adipose tissue (AT) gene expression and lipid profiles would occur in response to diet. Subcutaneous AT samples were thus collected from the dewlaps of n-3 and n-6 dairy cows at 1mo antepartum, and 1wk, 2mo, and 5mo postpartum for the analysis of lipids and gene expression. Lipid profiles were obtained by matrix-assisted laser desorption/ionization time of-flight mass spectrometry in both positive and negative modes. We found 37 lipid species in the 200 to 1,200 m/z range, which differed between the n-3 and control groups, suggesting that the n-3 supplement affected the lipid composition through the enrichment of lipids integrating long-chain PUFA from fish oil sources: eicosapentaenoic and docosahexaenoic acid. Moreover, a decrease in triacylglycerolipids was observed in AT of n-3 supplemented cows. The expression of 44 genes involved in fatty acid metabolism and the adipokine system was assessed by real-time reverse-transcription PCR. Hierarchical clustering, according to either postpartum stage or diet, enabled us to group genes exhibiting similar kinetic properties during lactation or by those that varied in similar ways after n-3 supplementation, respectively. Among the genes exhibiting a dietary effect, FABP4, LIPE, CD36, and PLIN1 were overexpressed in n-3 AT samples compared with the control, suggesting an increase in lipolysis due to n-3 supplementation, which was reflected on lipolytic activity at the protein level (i.e., protein expression of fatty acid binding protein 4, phosphorylated perilipin 1, and phosphorylated hormone-sensitive lipase). This increase in lipolysis is relevant to the decrease in triglycerides observed in these samples. Gene expression analyses between n-3 and control AT samples also suggested that the n-3 diet could modulate the secretory functions of AT, possibly by affecting adipokine expression; however, this has to be confirmed at the protein level.

AB - The National Animal Nutrition Program "National Research Support Project 9" supports efforts in livestock nutrition, including the National Research Council's committees on the nutrient requirements of animals. Our objective was to review the status of experimentation and data reporting in animal nutrition literature and to provide suggestions for the advancement of animal nutrition research and the ongoing improvement of field-applied nutrient requirement models. Improved data reporting consistency and completeness represent a substantial opportunity to improve nutrition-related mathematical models. We reviewed a body of nutrition research; recorded common phrases used to describe diets, animals, housing, and environmental conditions; and proposed equivalent numerical data that could be reported. With the increasing availability of online supplementary material sections in journals, we developed a comprehensive checklist of data that should be included in publications. To continue to improve our research effectiveness, studies utilizing multiple research methodologies to address complex systems and measure multiple variables will be necessary. From the current body of animal nutrition literature, we identified a series of opportunities to integrate research focuses (nutrition, reproduction and genetics) to advance the development of nutrient requirement models. From our survey of current experimentation and data reporting in animal nutrition, we identified 4 key opportunities to advance animal nutrition knowledge: (1) coordinated experiments should be designed to employ multiple research methodologies; (2) systems-oriented research approaches should be encouraged and supported; (3) publication guidelines should be updated to encourage and support sharing of more complete data sets; and (4) new experiments should be more rapidly integrated into our knowledge bases, research programs and practical applications. PMID- 27692711 TI - Organic dairy farmers put more emphasis on production traits than conventional farmers. AB - The overall aim of this research was to characterize the preferences of Danish dairy farmers for improvements in breeding goal traits. The specific aims were (1) to investigate the presence of heterogeneity in farmers' preferences by means of cluster analysis, and (2) to associate these clusters with herd characteristics and production systems (organic or conventional). We established a web-based survey to characterize the preferences of farmers for improvements in 10 traits, by means of pairwise rankings. We also collected a considerable number of herd characteristics. Overall, 106 organic farmers and 290 conventional farmers answered the survey, all with Holstein cows. The most preferred trait improvement was cow fertility, and the least preferred was calving difficulty. By means of cluster analysis, we identified 4 distinct clusters of farmers and named them according to the trait improvements that were most preferred: Health and Fertility, Production and Udder Health, Survival, and Fertility and Production. Some herd characteristics differed between clusters; for example, farmers in the Survival cluster had twice the percentage of dead cows in their herds compared with the other clusters, and farmers that gave the highest ranking to cow and heifer fertility had the lowest conception rate in their herds. This finding suggests that farmers prefer to improve traits that are more problematic in their herd. The proportion of organic and conventional farmers also differed between clusters; we found a higher proportion of organic farmers in the production-based clusters. When we analyzed organic and conventional data separately, we found that organic farmers ranked production traits higher than conventional farmers. The herds of organic farmers had lower milk yields and lower disease incidences, which might explain the high ranking of milk production and the low ranking of disease traits. This study shows that heterogeneity exists in farmers' preferences for improvements in breeding goal traits, that organic and conventional farmers differ in their preferences, and that herd characteristics can be linked to different farmer clusters. The results of this study could be used for the future development of breeding goals in Danish Holstein cows and for the development of customized total merit indices based on farmer preferences. PMID- 27692712 TI - Genetic changes of survival traits over the past 25 yr in Dutch dairy cattle. AB - Genetic correlations and heritabilities for survival were investigated over a period of 25 yr to evaluate if survival in first lactation has become a different trait and if this is affected by adjusting for production level. Survival after first calving until 12mo after calving (surv_12mo) and survival of first lactation (surv_1st_lac) were analyzed in Dutch black-and-white cows. The data set contained 1,108,745 animals for surv_12mo and 1,062,276 animals for surv_1st_lac, with first calving between 1989 and 2013. The trait survival as recorded over 25 yr was split in five 5-yr intervals to enable a multitrait analysis. Bivariate models using subsets of the full data set and multitrait and autoregressive models using the full data set were used. Survival and functional survival were analyzed. Functional survival was defined as survival adjusted for within-herd production level for 305-d yield of combined kilograms of fat and protein. Mean survival increased over time, whereas genetic variances and heritability decreased. Bivariate models yielded large standard errors on genetic correlations due to poor connectedness between the extreme 5-yr intervals. The more parsimonious models using the full data set gave nonunity genetic correlations. Genetic correlations for survival were below 0.90 between intervals separated by 1 or more 5-yr intervals. Genetic correlations for functional survival did not indicate that definition of survival changed (>=0.90). The difference in genetic correlations between survival and functional survival is likely explained by lower emphasis of dairy farmers on culling in first lactation for low yield in more recent years. This suggests that genetic evaluation for longevity using historical data should analyze functional survival rather than survival. PMID- 27692713 TI - Short communication: A novel method using immunomagnetic separation with a fluorescent nanobeads lateral flow assay for the rapid detection of low concentration Escherichia coli O157:H7 in raw milk. AB - Escherichia coli O157:H7 is an important serotype of enterohemorrhagic E. coli that was first identified as a human pathogen in 1982. This pathogen causes several serious diseases. In this study, immunomagnetic separation was coupled with a fluorescent nanobeads lateral flow assay to establish a sensitive and rapid detection method for Escherichia coli O157:H7 in raw milk. The pathogen was captured from raw milk by immunomagnetic separation with immunomagnetic nanobeads and then detected using a fluorescent nanobeads lateral flow assay. A fluorescent line was formed in the test line of the test strip and quantitatively detected using a fluorescent reader. Screening times, which included immunomagnetic separation and the fluorescent nanobeads lateral flow assay, were 8, 7, 6, and 5h when 1, 5, 25, and 125 cfu of E. coli O157:H7, respectively, were inoculated into 25mL of raw milk. The established method could be widely applied to the rapid onsite detection of other pathogens to ensure food safety. PMID- 27692714 TI - Factors responsible for subclinical mastitis in cows caused by Staphylococcus chromogenes and its susceptibility to antibiotics based on bap, fnbA, eno, mecA, tetK, and ermA genes. AB - The aim of this study was to recognize selected factors of virulence determining the adhesion of Staphylococcus chromogenes to cows' udder tissues in subclinical mastitis and to evaluate the susceptibility of this pathogen to antibiotics. The subjects of the study were 38 isolates of Staph. chromogenes from 335 samples of milk from cows with subclinical coagulase-negative staphylococci mastitis. Somatic cell count ranged between 216,000 and 568,000/mL of milk (average 356,000/mL of milk). We confirmed the ability to produce slime in 24 isolates (63.2%), and the ability to produce protease in 29 isolates (76.3%). In each slime-producing isolate, the bap gene was not found, and the fnbA and eno genes were not detected. In vitro tests showed that ceftiofur had the highest effectiveness against Staph. chromogenes (89.5% of susceptible isolates). Minimum inhibitory concentrations ranged from 0.06 to 2ug/mL for susceptible isolates. The minimum concentrations required to inhibit growth of 90 and 50% of the isolates for ceftiofur were at or below the cutoffs recommended by the Clinical and Laboratory Standards Institute (2 and 0.06ug/mL, respectively). A significant percentage of the isolates were susceptible to other beta-lactam antibiotics: amoxicillin with clavulanic acid (84.2%) and ampicillin (81.6%). The lowest effectiveness among beta-lactams was for penicillin (73.7% of susceptible isolates), and the minimum inhibitory concentration for penicillin ranged from <0.06 to 8ug/mL. None of the examined isolates had the mecA gene, but beta lactamase was detected in 4 isolates (10.5%). Erythromycin and oxytetracycline exhibited the lowest activity against Staph. chromogenes (71.1 and 63.2% of susceptible isolates, respectively). The genes tetK (6 isolates) and ermA (1 isolate) were also detected. PMID- 27692715 TI - Evaluation of modified stainless steel surfaces targeted to reduce biofilm formation by common milk sporeformers. AB - The development of bacterial biofilms on stainless steel (SS) surfaces poses a great threat to the quality of milk and other dairy products as the biofilm embedded bacteria can survive thermal processing. Established biofilms offer cleaning challenges because they are resistant to most of the regular cleaning protocols. Sporeforming thermoduric organisms entrapped within biofilm matrix can also form heat-resistant spores, and may result in a long-term persistent contamination. The main objective of this study was to evaluate the efficacy of different nonfouling coatings [AMC 18 (Advanced Materials Components Express, Lemont, PA), Dursan (SilcoTek Corporation, Bellefonte, PA), Ni-P polytetrafluoroethylene (PTFE, Avtec Finishing Systems, New Hope, MN), and Lectrofluor 641 (General Magnaplate Corporation, Linden, NJ)] on SS plate heat exchanger surfaces, to resist the formation of bacterial biofilms. It was hypothesized that modified SS surfaces would promote a lesser amount of deposit buildup and bacterial adhesion as compared with the native SS surface. Vegetative cells of aerobic sporeformers, Geobacillus stearothermophilus (ATCC 15952), Bacillus licheniformis (ATCC 6634), and Bacillus sporothermodurans (DSM 10599), were used to study biofilm development on the modified and native SS surfaces. The adherence of these organisms, though influenced by surface energy and hydrophobicity, exhibited no apparent relation with surface roughness. The Ni-P PTFE coating exhibited the least bacterial attachment and milk solid deposition, and hence, was the most resistant to biofilm formation. Scanning electron microscopy, which was used to visualize the extent of biofilm formation on modified and native SS surfaces, also revealed lower bacterial attachment on the Ni-P-PTFE as compared with the native SS surface. This study thus provides evidence of reduced biofilm formation on the modified SS surfaces. PMID- 27692716 TI - Milk acidification to control the growth of Mycoplasma bovis and Salmonella Dublin in contaminated milk. AB - Bacterial contamination of milk fed to calves compromises calf health. Several bacterial pathogens that infect cows, including Mycoplasma bovis and Salmonella enterica ssp. enterica serovar Dublin, are shed in milk, providing a possible route of transmission to calves. Milk acidification lowers the milk pH so that it is unsuitable for bacterial growth and survival. The objectives of this study were to (1) determine the growth of M. bovis and Salmonella Dublin in milk, and (2) evaluate the efficacy of milk acidification using a commercially available acidification agent (Salstop, Impextraco, Heist-op-den-Berg, Belgium) to control M. bovis and Salmonella Dublin survival in milk. For the first objective, 3 treatments and a positive control were prepared in 10 mL of milk and broth, respectively, and inoculated with M. bovis or Salmonella Dublin to an approximate concentration of 104 cfu/mL. Each treatment was retained at 5, 23, or 37 degrees C with the positive control at 37 degrees C. Aliquots were taken at 4, 8, 24, 28, 32, 48, 52, and 56 h after inoculation and transferred onto agar medium in triplicate following a 10-fold dilution series in sterile phosphate-buffered saline. All plates were incubated and colonies counted. For the second objective, 4 treatments and a positive control were prepared with 100 mL of milk and inoculated with M. bovis or Salmonella Dublin to an approximate concentration of 106 cfu/mL. With the use of Salstop, treatments were adjusted to an approximate pH of 6, 5, 4, or 3.5. The positive control was left untreated. At 1, 2, 4, 6, 8, and 24 h after treatment, triplicate aliquots were taken, the pH measured, and then the aliquots were transferred onto agar medium and into broth for enrichment. Following incubation, agar colonies were counted, while broths were plated and incubated prior to colonies being counted. All trials were repeated. Mycoplasma bovis did not grow in milk, but Salmonella Dublin proliferated. The pH of all acidification treatments remained stable for 24 h. No viable M. bovis organisms were detected at 1 h of exposure to pH 3.5 and 4 or at 8 h of exposure to pH 5. Following 24 h of exposure to pH 6 M. bovis remained viable. No viable Salmonella Dublin organisms were detected at 2 and 6 h of exposure to pH 3.5 and 4, respectively. Salmonella Dublin remained viable following 24 h of exposure to pH 5 and 6. These results demonstrate that milk acidification using Salstop is effective at eliminating viable M. bovis and Salmonella Dublin organisms in milk if the appropriate pH and exposure time are maintained.

AB - Forage neutral detergent fiber (NDF) content and particle size are important factors that affect rumen function. The aim of the current study was to evaluate the effects on rumen health, NDF digestibility, and animal performance of pelleting a forage-based diet. Eight Holstein heifers (age 336+/-30d, body weight 346+/-35kg) were randomly assigned to a repeated crossover design. Animals were housed in tie-stalls and fed for ad libitum intake. The study included 4 periods of 3 wk, the first 2 wk for adaptation to the diet and the last wk for data collection. Diets had the same ingredients but had a different physical form: total mixed ration (TMR) and pellet (diameter=8mm). The physically effective NDF (peNDF) differed between the 2 treatments (39.8 and 11.8% of NDF in the TMR and pellet diets, respectively). During the trial, dry matter intake (DMI), water intake, rumination time, rumen temperature, and pH were evaluated daily. Fecal samples were collected in wk3 of each period to determine total-tract digestibility of the potential digestible (pd)NDF. Average daily gain and feed conversion ratio were calculated at the end of each period. With the pellet diet, DMI, DMI/body weight, and water consumption were higher. We observed no significant difference in average daily gain or feed conversion ratio. Rumination time was lower for the pellet diet than for the TMR diet (241 vs. 507min/d, respectively). Diet had no effect on rumen temperature or rumen pH. The total tract digestibility of the pdNDF was greater with the TMR diet than with the pellet diet (90.25 vs. 86.82% pdNDF, respectively). The results of the current study suggest that a complete-feed pellet diet was well accepted by the animals, as demonstrated by higher DMI. Rumination time was reduced with the pellet diet, but rumen pH was not different. The pdNDF digestibility was high for both diets, but significantly higher for the TMR diet. Given that animal performance was similar between the 2 diets, although they differed with respect to DMI and fiber digestion, we hypothesize that the 2 diets had different retention times, related to their physical form. A complete-feed pellet diet formulated to provide a sufficient level of NDF from forages could be fed to growing ruminants without apparent negative effects on rumen health and animal productivity, at least for a short period. More research over a longer growing period is needed before recommending this feeding strategy for growing heifers. PMID- 27692718 TI - Comparative risk assessment for new cow-level Mycobacterium avium ssp. paratuberculosis infections between 3 dairy production types: Organic, conventional, and conventional-grazing systems. AB - Johne's disease, a granulomatous enteritis of ruminant animals, is a hidden threat on dairy farms, adversely affecting animal welfare as well as herd productivity. Control programs in the United States advocate for specific management practices to temper the spread of the causal organism (Mycobacterium avium ssp. paratuberculosis, MAP), such as improving calving area hygiene and limiting introduction of replacement stock with unknown infection status. A need remains for direct exploration of Johne's disease prevention strategies in the United States with respect to production type. Alongside the growing demand for organic products, the safety of organic dairy practices with respect to MAP control is warranted. Further, conventional herds for which organic practices such as pasture grazing are used should be situated within the risk spectrum. We developed a risk assessment model using the US Voluntary Bovine Johne's Disease Control Program as a framework, with the goal of evaluating the risk of new cow level MAP infections. A total of 292 organic and conventional farms in 3 states were surveyed on management practices, and an overall analysis was conducted in which each farm was first scored on individual practices using a range of "no risk" to "high risk," according to the literature. The sum of all risk factors was then analyzed to quantify and compare the risk burden for each production type. Organic herds received higher overall risk scores compared with both conventional grazing and nongrazing subtypes. To identify which factors contributed to the overall increased risk for organic herds, the management practices were categorized and evaluated by logistic regression. We determined that the increased risk incurred by organic herds was predominantly due to decisions made in the calving area and preweaned calf group. However, although certain individual risk factors related to calf management are commonly involved in prevention strategies (e.g., cow/calf separation) and were thus included in the overall risk assessment, empirical evidence linking them to the spread of MAP is lacking. Instead, these factors are problematic when executed with other management decisions, leading to a hypothesized synergism of transmission risk. To this end, we developed a set of compound risk factors, which were also evaluated as outcomes in logistic regression models, with production type serving as the predictor of interest. Organic farms in our study were more susceptible to risks associated with the synergism of study variables. Notably, organic producers were most likely to allow calves to spend extended time with the dam, while also lacking a dedicated calving area. Additionally, calves in organic herds were more often permitted to nurse even with poor udder hygiene on farm. A heightened vigilance toward calving area hygiene is therefore indicated for these herds. PMID- 27692719 TI - Effects of maturity at ensiling of bermudagrass and fibrolytic enzyme application on the performance of early-lactation dairy cows. AB - The objective of this study was to examine effects of adding fibrolytic enzymes to diets containing bermudagrass ensiled after 4 or 7wk of regrowth on the diet digestibility, ruminal fermentation and performance of lactating cows, and the interaction of the treatments. In experiment 1, 64 Holstein cows (22+/-4d in milk) were assigned to an experiment with a 2*2 factorial treatment arrangement and a 56-d duration. Treatments were diets containing 4 or 7wk regrowth bermudagrass silage without or with an exogenous fibrolytic enzyme cocktail. The cellulase-xylanase enzyme was applied at 2.33g/kg of total mixed ration dry matter (DM) during mixing immediately before feeding. Experiment 2 was aimed at examining treatment effects on the ruminal fermentation profile. Four ruminally cannulated cows were assigned to the 4 treatments using a 4*4 Latin square design with 14-d periods. No enzyme by maturity interaction was detected for any measurement. Regardless of forage maturity, applying the fibrolytic enzyme did not affect DM intake, milk yield, apparent digestibility, feed efficiency, energy balance, and ruminal fermentation though it tended to increase milk lactose concentration (4.88 vs. 4.81%). Feeding the 4-wk diet instead of the 7-wk diet increased DM intake (22.4 vs. 21.3kg/d), digestibility of DM, neutral detergent fiber, and acid detergent fiber, and tended to increase 3.5%-fat corrected milk yield (47.2 vs. 44.3kg/d) and milk fat yield (1.88 vs. 1.73kg/d). Therefore, daily intake of net energy and secretion of milk energy were greater for the 4-wk diet. In addition, the 4-wk diet increased the ruminal concentrations of acetate, propionate, valerate, lactate, and total volatile fatty acids, and decreased ruminal pH, without affecting the acetate:propionate ratio. Feeding fibrolytic enzymes did not improve the performance of early-lactation dairy cows, but harvesting the forage earlier tended to improve milk production. PMID- 27692721 TI - Sustainable breeding objectives and possible selection response: Finding the balance between economics and breeders' preferences. AB - To optimize breeding objectives of Fleckvieh and Brown Swiss cattle, economic values were re-estimated using updated prices, costs, and population parameters. Subsequently, the expected selection responses for the total merit index (TMI) were calculated using previous and newly derived economic values. The responses were compared for alternative scenarios that consider breeders' preferences. A dairy herd with milk production, bull fattening, and rearing of replacement stock was modeled. The economic value of a trait was derived by calculating the difference in herd profit before and after genetic improvement. Economic values for each trait were derived while keeping all other traits constant. The traits considered were dairy, beef, and fitness traits, the latter including direct health traits. The calculation of the TMI and the expected selection responses was done using selection index methodology with estimated breeding values instead of phenotypic deviations. For the scenario representing the situation up to 2016, all traits included in the TMI were considered with their respective economic values before the update. Selection response was also calculated for newly derived economic values and some alternative scenarios, including the new trait vitality index (subindex comprising stillbirth and rearing losses). For Fleckvieh, the relative economic value for the trait groups milk, beef, and fitness were 38, 16, and 46%, respectively, up to 2016, and 39, 13, and 48%, respectively, for the newly derived economic values. Approximately the same selection response may be expected for the milk trait group, whereas the new weightings resulted in a substantially decreased response in beef traits. Within the fitness block, all traits, with the exception of fertility, showed a positive selection response. For Brown Swiss, the relative economic values for the main trait groups milk, beef, and fitness were 48, 5, and 47% before 2016, respectively, whereas for the newly derived scenario they were 40, 14, and 39%. For both Brown Swiss and Fleckvieh, the fertility complex was expected to further deteriorate, whereas all other expected selection responses for fitness traits were positive. Several additional and alternative scenarios were calculated as a basis for discussion with breeders. A decision was made to implement TMI with relative economic values for milk, beef, and fitness with 38, 18, and 44% for Fleckvieh and 50, 5, and 45% for Brown Swiss, respectively. In both breeds, no positive expected selection response was predicted for fertility, although this trait complex received a markedly higher weight than that derived economically. An even higher weight for fertility could not be agreed on due to the effect on selection response of other traits. Hence, breeders decided to direct more attention toward the preselection of bulls with regard to fertility. PMID- 27692720 TI - Short communication: Relationship of activity and rumination to abundance of pest flies among organically certified cows fed 3 levels of concentrate. AB - The objectives of this study were to evaluate activity, rumination time, and their association with 3 kinds of pasture flies for organic dairy cows (n=57) fed 3 grain supplementation strategies during the grazing season from May to September 2013. Cows were assigned to 1 of 3 replicate supplementation groups: (1) no corn-grain supplementation (100% pasture, PAS, n=19); (2) low corn-grain (2.72kg/cow per day, LG, n=19); and (3) high corn-grain (5.44kg/cow per day, HG, n=19). Cows calved during 2 seasons (fall and spring) at the University of Minnesota West Central Research and Outreach Center, Morris, from October to December 2012 and March to May 2013. Supplement (corn-grain and minerals) was fed in a total mixed ration of corn silage and alfalfa silage, and at least 30% of diet dry matter intake for LG and HG cows consisted of pasture. Activity and rumination time (daily and 2-h blocks of time) were monitored electronically using HR-LD tags (SCR Engineers Ltd., Netanya, Israel) for 125d. Activity (cow body movement and head movement) was reported in activity units from SCR DataFlow II software, and rumination times were reported in minutes per day. PROC HPMIXED in SAS (SAS Institute Inc., Cary, NC) was used for statistical analysis, and independent variables were season of calving (fall or spring), month of grazing (June to September), supplementation group, and interactions of month of grazing and supplementation group. Replicate was a random effect with repeated measures. Daily activity was higher for PAS cows (1,138 activity units) than for HG cows (1,001 activity units), and LG cows (1,019 activity units). Daily activity was highest in July (1,258 activity units) and lowest in September (819 activity units). Rumination was not different for PAS (397min/d), LG (384min/d), or HG (370min/d) cows. Daily rumination was greater in September (402min/d) than in July (361min/d). Daily activity increased rapidly between 0600-0800h and 1600 1800h. From 1800 to 2000h, cows had a rapid decline in activity until 0600h the next day. All supplementation groups had the greatest rumination activity from 0200 to 0400h and the least between 1000 and 1200h. Greater activity of cows on a herd basis was moderately correlated with increased fly populations. Monthly activity patterns of grazing cows were associated with fly populations on cows. PMID- 27692722 TI - Genotype by environment interaction for activity-based estrus traits in relation to production level for Danish Holstein. AB - The objective of this study was to investigate whether genotype by environment interaction exists for female fertility traits and production of energy-corrected milk at 70d in milk (ECM70). Fertility traits considered were the activity-based estrus traits interval from calving to first high activity (CFHA), duration of high activity episode (DHA), as an indicator for first estrus duration, and strength of high activity episode (SHA), as an indicator for first estrus strength. The physical activity traits were derived from electronic activity tags for 11,522 first-parity cows housed in 125 commercial dairy herds. Data were analyzed using a univariate random regression animal model (URRM), by regressing the phenotypic performance on the average herd ECM70 as an environmental gradient. Furthermore, the genetic correlations between CFHA and ECM70 as a function of production level were estimated using a bivariate random regression animal model (BRRM). For all traits, heterogeneity of additive genetic variances and heritability estimates was observed. The heritability estimate for CFHA decreased from 0.25 to 0.10 with increasing production level and the heritability estimate for ECM70 decreased from 0.35 to 0.15 with increasing production level using URRM. The genetic correlation of the same trait in low and high production levels was around 0.74 for CFHA and 0.80 for ECM70 using URRM, but when data were analyzed using the multiple-trait analysis (MT), genetic correlation estimates between low and high production levels were not significantly different from unity. Furthermore, the genetic correlation of SHA between low and high production level was 0.22 using URRM, but the corresponding correlation estimate had large standard error when data were analyzed using MT. The genetic correlation between CFHA and ECM70 as a function of production environment was weak but unfavorable and decreased slightly from 0.09 to 0.04 with increasing production level using BRRM. Moreover, the same trend was observed when the data were analyzed using MT where the genetic correlation between CFHA and ECM70 in the low production environment was 0.29 compared with -0.13 in the high production environment, but these estimates had large standard errors. In conclusion, regardless of the trait used, in relation to average herd ECM70 production, the results indicated no clear evidence of strong genotype by environment interaction that would cause significant re-ranking of sires between low and high production environments. PMID- 27692723 TI - Associations of high and low milk protein concentrations with energy allocation, milk production, and concentrations of blood plasma metabolites and hormones in Holstein-Friesian cows. AB - A positive association between milk protein concentration (MPC) and reproductive performance in dairy cows has been shown in several studies globally. This association may positively influence farm productivity and profitability, particularly in seasonally calving, pasture-based herds. However, the differences in milk production and energy allocation, physical characteristics, and blood plasma nutrient status between cows with differing MPC have not been examined, and the underlying mechanisms responsible for the association remain undefined. The objective of this study was to examine associations between MPC and nutrient partitioning in primiparous Holstein-Friesian cows managed under pasture-based dairying conditions, and to identify differences that may indicate the underlying mechanisms. Data were collected from 85 cows at regular intervals during the early part of the 2013 to 2014 seasonal lactation, including daily milk yield, weekly milk composition, weekly body condition score measurements, as well as weekly blood plasma metabolite and hormone concentrations. Cows were retrospectively separated into quartiles based on their average MPC during the first 120d of lactation, and comparisons were made between cows within the highest (high; 3.22 to 3.40%) and the lowest (low; 2.87 to 3.00%) MPC quartiles. The high-MPC cows had lower daily milk yields, yet did not differ in the daily yields of milk solids (protein + fat) compared with the low-MPC cows. After parturition, the high-MPC cows had greater blood plasma concentrations of glucose, insulin, insulin-like growth factor-1 and leptin compared with the low MPC cows and maintained their body condition score, despite no differences in these variables prepartum. These results indicate an increased partitioning of nutrients toward milk synthesis at the expense of body condition for cows in the low MPC quartile. However, average daily energy outputs in milk were similar in the high- and low-MPC cows. The high-MPC cows calved 12d earlier in the seasonal calving period, reflecting superior reproductive performance when cows in this quartile were 15mo of age. These results suggest that at least part, but not all, of the reported associations between MPC and dairy cow fertility are related to nutrient status during early lactation. Further research is required to understand and use the association. PMID- 27692724 TI - The Impact of Language on Voice: An LTAS Study. AB - OBJECTIVES: The present study investigates possible differences in sound characteristics associated with Farsi and Qashqai produced by Farsi-Qashqai bilinguals. STUDY DESIGN: This is a descriptive-analytical and cross-sectional study. METHODS: Thirty-two Farsi-Qashqai bilinguals (16 men and 16 women) participated in the study. Mean spectral energy (MSE) and spectral tilt (ST) obtained from long-term average speech spectra were extracted from continuous speech samples of Farsi-Qashqai bilingual speakers. MSE and ST were calculated using Praat and then compared between Farsi and Turkish. RESULTS: Results showed that bilingual speakers had higher MSE and lower ST in Farsi than in Turkish. CONCLUSIONS: Findings show that even with the same phonatory apparatus, spoken language affects the speaker's voice quality. PMID- 27692725 TI - Impact of Cricothyroid Muscle Contraction on Vocal Fold Vibration: Experimental Study with High-Speed Videoendoscopy. AB - OBJECTIVES: The aim of this study was to evaluate the effects of cricothyroid muscle contraction on vocal fold vibration, as evaluated with high-speed videoendoscopy, and to identify one or more aspects of vocal fold vibration that could be used as an irrefutable indicator of unilateral cricothyroid muscle paralysis. STUDY DESIGN: This was an experimental study employing excised human larynges. METHODS: Twenty freshly excised human larynges were evaluated during artificially produced vibration. Each larynx was assessed in three situations: bilateral cricothyroid muscle contraction, unilateral cricothyroid muscle contraction, and no contraction of either cricothyroid muscle. The following parameters were evaluated by high-speed videoendoscopy: fundamental frequency, periodicity, amplitude of vocal fold vibration, and phase symmetry between the vocal folds. RESULTS: Although neither unilateral nor bilateral cricothyroid muscle contraction altered the periodicity of vibration or the occurrence of phase asymmetry, there was a significant decrease in fundamental frequency in parallel with decreasing longitudinal tension. We also found an increase in vibration amplitude of right and left vocal folds, which were similar in terms of their behavior for this parameter in the various situations studied. CONCLUSION: Our results suggest that differences in vibration amplitude and phase symmetry between vocal folds are not reliable indicators of unilateral cricothyroid muscle paralysis. PMID- 27692726 TI - Critical Limb Ischemia: An Expert Statement. AB - Critical limb ischemia (CLI), the most advanced form of peripheral artery disease, is associated with significant morbidity, mortality, and health care resource utilization. It is also associated with physical, as well as psychosocial, consequences such as amputation and depression. Importantly, after a major amputation, patients are at heightened risk of amputation on the contralateral leg. However, despite the technological advances to manage CLI with minimally invasive technologies, this condition often remains untreated, with significant disparities in revascularization and amputation rates according to race, socioeconomic status, and geographic region. Care remains disparate across medical specialties in this rapidly evolving field. Many challenges persist, including appropriate reimbursement for treating complex patients with difficult anatomy. This paper provides a comprehensive summary that includes diagnostic assessment and analysis, endovascular versus open surgical treatment, regenerative and adjunctive therapies, and other important aspects of CLI. PMID- 27692727 TI - Can TAVR Make Me Smarter? PMID- 27692728 TI - Serial Changes in Cognitive Function Following Transcatheter Aortic Valve Replacement. AB - BACKGROUND: Data regarding the mid- to long-term cognitive trajectory of transcatheter aortic valve (TAVR) recipients are scarce. OBJECTIVES: Changes in global cognition and specific cognitive domains up to 1 year post-TAVR were evaluated. METHODS: Fifty-one patients (median age 80.0 [interquartile range: 72.0 to 85.0] years; 37% women) underwent TAVR and prospective assessment of cognitive function using the Montreal Cognitive Assessment (MoCA) at baseline, short-term (30 days), and 1 year post-TAVR. Processing speed and executive cognitive functions were further evaluated with the digit-symbol substitution test (DSST), Trail Making Tests (TMT), and verbal fluency tests at the same time points. Cognitive decline (CD) was determined by changes in mean scores and as a rate using practice-corrected reliable change index (RCI). RESULTS: The baseline mean total MoCA score was 22.71 +/- 3.84. Twenty patients (39.2%) were considered cognitively impaired using a cutoff of <23 of 30 points. Mean total MoCA score improved at short-term post-TAVR and remained stable at 1 year (p = 0.022). On the basis of the RCI of total MoCA score, 4 patients (7.8%) presented with short term CD, which persisted at 1 year in 1 patient (2.0%). Four patients (7.8%) exhibited cognitive improvement at 1 year, increasing to 15% among those with baseline cognitive impairment. No significant changes were observed over time in the mean DSST, TMT, and verbal fluency test scores. On the basis of the RCI, 10 of 40 patients (25%) presented with a reduction in performance of at least 1 test at 30 days that persisted at 1 year in 4 patients (10%). CONCLUSIONS: TAVR was associated with global improvement in cognitive status, more pronounced among those with cognitive impairment pre-TAVR. However, early decline in some complex cognitive functions was observed in one-quarter of TAVR recipients, persisting at 1 year in 10% of patients. PMID- 27692729 TI - Midkine is up-regulated in both cancerous and inflamed bowel, reflecting lymph node metastasis in colorectal cancer and clinical activity of ulcerative colitis. AB - Midkine is a multifunctional cytokine and growth factor displaying proinflammatory and pro-tumorigenic activity. Its association with bowel diseases has not been fully elucidated. Our purpose was to delineate midkine expression pattern by RT-qPCR in inflamed/cancerous bowel (n=208) and whole blood (n=150) in colorectal cancer (CRC), Crohn's disease (CD), and ulcerative colitis (UC) and to evaluate midkine dynamics in early postoperative period following colorectal surgery. The expression of midkine was significantly up-regulated in stage III CRC and independently associated with lymph node metastasis. The expression of midkine in whole blood was up-regulated solely in N1 CRC. Midkine expression in cancer-free tissue (CRC) was also elevated and dependent on CRC advancement. In IBD, inflammation increased the bowel expression of midkine solely in UC, in a manner proportional to the disease clinical activity. Large and small bowel differed with respect to the expression of midkine in quiescent tissue (higher in small bowel) and to its correlation pattern with chemokines (in a large bowel) and angiogenic factors and cell cycle regulators (in a small bowel). Circulating midkine and its expression in whole blood dropped directly following colorectal surgery; however, the concentration of midkine in serum was restored on postoperative day three. Midkine is involved in bowel inflammation in UC and lymph node metastasis in CRC, rendering midkine an attractive target for their treatment. Owing to midkine elevation in early postoperative period and its overexpression in tumor-adjacent tissue, targeting midkine might be considered also as a prevention of CRC recurrence following curative tumor resection.

AB - INTRODUCTION: An increasing number of patients with prostate cancer (PC) are diagnosed and treated. The aim of this study was to investigate urinary incontinence (UI) and sexual dysfunction (SD) two years after treatment for localized prostate cancer (PC). METHODS: This study followed all cases of localized PC diagnosed between 2008 and 2009 in men aged<=65years old and still alive two years after treatment. In total, 437 men were recruited. Data were collected using a standardized questionnaire and by cross-checking with data from the cancer registry. Descriptive and comparative analyses were performed to evaluate persisting UI and SD at 2years. RESULTS: At two years after treatment, UI was persistent in 48.8%; 41.2% had used urinary protections, and 39.2% had used at least 1 pad/day; 55.2% reported financial difficulties for purchasing protective pads. In total, 22.7% did not consult a specialist for UI. SD was persistent in 82.8%; 30.4% did not consult a specialist for SD. SD had a negative impact on the sex life of patients and their partners. After adjustment for cancer stage, prostatectomy was significantly associated with persisting UI and SD at two years. CONCLUSION: Two years after treatment, rates of persisting UI and/or SD remain high. Treatment by prostatectomy was significantly associated with an increased risk of persisting adverse effects at two years. The different toxicities between treatments should be presented to patients before initiating therapy in order to encourage the patient to contributed to shared treatment decision-making. PMID- 27692731 TI - [Prevalence and management of pain in patients with metastatic cancer in Franche Comte]. AB - INTRODUCTION: Pain management is a major public health problem, especially in oncology. In order to assess professional practice, the IRFC-FC conducted a survey amongst patients with metastatic osteophilic solid tumor in Franche-Comte. The aims were to assess the pain prevalence, and its characteristics, its management and its impact on patients' quality of life in patients in pain. METHODS: An observational, prospective and multicenter survey was conducted using a self-report questionnaire. Patients with metastatic breast or prostate cancer managed in 5 day-hospitals of the IRFC-FC over a period of three months were included. RESULTS: Two hundred thirty-three questionnaires were analyzed. Pain prevalence rate was 48.5%. Three quarters of patients in pain had chronic background pain, moderate to severe, with or without breakthrough pain. Considering their pain intensity and their analgesic therapy, 42.0% of patients seem to have an inadequate treatment. Eighty-five percent of treated patients reported to be compliant and felt that their pain was well managed despite a strong impact on their quality of life. CONCLUSION: The setting of a specific clinical pathway is essential to secure the standardized, optimal and efficient management of patients in pain. The assessment of patient satisfaction and quality of life must be integrated in clinical practice to identify patients in pain for which the treatment is inappropriate. PMID- 27692732 TI - Variation among pathologists' treatment suggestions for melanocytic lesions: A survey of pathologists. AB - BACKGROUND: The extent of variability in treatment suggestions for melanocytic lesions made by pathologists is unknown. OBJECTIVE: We investigated how often pathologists rendered suggestions, reasons for providing suggestions, and concordance with national guidelines. METHODS: We conducted a cross-sectional survey of pathologists. Data included physician characteristics, experience, and treatment recommendation practices. RESULTS: Of 301 pathologists, 207 (69%) from 10 states (California, Connecticut, Hawaii, Iowa, Kentucky, Louisiana, New Jersey, New Mexico, Utah, and Washington) enrolled. In all, 15% and 7% reported never and always including suggestions, respectively. Reasons for offering suggestions included improved care (79%), clarification (68%), and legal liability (39%). Reasons for not offering suggestions included referring physician preference (48%), lack of clinical information (44%), and expertise (29%). Training and caseload were associated with offering suggestions (P < .05). Physician suggestions were most consistent for mild/moderate dysplastic nevi and melanoma. For melanoma in situ, 18 (9%) and 32 (15%) pathologists made suggestions that undertreated or overtreated lesions based on National Comprehensive Cancer Network (NCCN) guidelines, respectively. For invasive melanoma, 14 (7%) pathologists made treatment suggestions that undertreated lesions based on NCCN guidelines. LIMITATIONS: Treatment suggestions were self reported. CONCLUSIONS: Pathologists made recommendations ranging in consistency. These findings may inform efforts to reduce treatment variability and optimize patterns of care delivery for patients.

PMID- 27692733 TI - Tofacitinib improves pruritus and health-related quality of life up to 52 weeks: Results from 2 randomized phase III trials in patients with moderate to severe plaque psoriasis. AB - BACKGROUND: Tofacitinib is an oral Janus kinase inhibitor that improves clinical measures of psoriasis. OBJECTIVE: We sought to assess patient-reported outcomes in tofacitinib-treated patients with moderate to severe plaque psoriasis over 52 weeks. METHODS: In 2 identical, phase III studies (Oral treatment for Psoriasis Trial Pivotal 1 [NCT01276639], n = 901, and Pivotal 2 [NCT01309737], n = 960), patients were randomized 2:2:1 to receive 5 or 10 mg of tofacitinib or placebo, twice daily. At week 16, placebo-treated patients were re-randomized to tofacitinib. Dermatology Life Quality Index score, Itch Severity Item score, Patient Global Assessment score, and patient satisfaction were assessed. RESULTS: Baseline Dermatology Life Quality Index score indicated substantial health related quality of life impairment. At week 16, a greater proportion of patients achieved Dermatology Life Quality Index score of 1 or less (no effect of psoriasis on health-related quality of life) with tofacitinib 5 and 10 mg twice daily versus placebo (Oral treatment for Psoriasis Trial Pivotal 1/2: 26.7%/28.6% and 40.2%/48.2% vs 4.6%/6.0%, respectively; P < .0001); improvements were maintained through week 52. Similar patterns were observed with Patient Global Assessment. Improvements in itch were particularly rapid, observed 1 day after treatment initiation for both tofacitinib doses versus placebo (P < .05). At week 16, more patients were satisfied with tofacitinib versus placebo (P < .0001). LIMITATIONS: Clinical nonresponders discontinued at week 28. CONCLUSIONS: Tofacitinib demonstrated improvement in health-related quality of life and patient-reported symptoms that persisted over 52 weeks. PMID- 27692735 TI - Intralesional triamcinolone for flares of hidradenitis suppurativa (HS): A case series. AB - BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory disease of the hair follicle. Standard practice of managing acute flares with corticosteroid injection lacks scientific evidence. OBJECTIVE: We sought to assess the outcomes of routine treatment using intralesional triamcinolone (triamcinolone acetonide 10 mg/mL) in the management of acute flares in HS. METHODS: This was a prospective case series evaluating the effect of intralesional corticosteroids for alleviation of acute flares in HS. Physician- and patient-reported outcomes were noted. RESULTS: Significant reductions in physician-assessed erythema (median score from 2-1, P < .0001), edema (median score from 2-1, P < .0001), suppuration (median score from 2-1, P < .0001), and size (median score from 3-1, P < .0001) was demonstrated at follow-up. A significant difference in patient reported pain visual analog scale scores occurred after 1 day (from 5.5-2.3, P < .005) and from day 1 to day 2 (from 2.3-1.4, P < .002). LIMITATIONS: Small study size, open single-arm design, and short follow-up time are the limitations of this study. CONCLUSION: Intralesional injection of corticosteroids is perceived as beneficial by physicians and patients in the management of HS flares by reducing pain after 1 day and signs of inflammation approximately 7 days later. PMID- 27692736 TI - The effect of smoking and age on the response to first-line therapy of hidradenitis suppurativa: An institutional retrospective cohort study. AB - BACKGROUND: Treatment for hidradenitis suppurativa is often empiric and inadequate, and determining which patients will respond is difficult. OBJECTIVE: We sought to determine which patient factors are associated with a positive response to first-line medical therapy. METHODS: A single-center retrospective cohort study of all patients with hidradenitis suppurativa seen between January 1, 1992, and October 1, 2014, was conducted. Response to first-line medical therapy (oral/topical antibiotics, intralesional corticosteroids, and topical washes) was examined at follow-up within 6 months of initiating therapy. A multivariate binary logistic regression model was built examining response to treatment and the interplay of patient factors and treatment initiated. RESULTS: In all, 198 patients were included in the final model. Nonsmokers (odds ratio 2.634, 95% confidence interval 1.301-5.332, P = .007) and older individuals (odds ratio 1.046 for each additional year, 95% confidence interval 1.020-1.072, P < .001) were more likely to have improvement at follow-up. In addition, current smokers differed significantly from nonsmokers in several regards. LIMITATIONS: The retrospective nature of this study is a limitation, as is relying on classification of disease severity from physical examination findings in some patients. CONCLUSIONS: The results of this study suggest that clinicians may be able to more accurately predict which patients with hidradenitis suppurativa will respond to first-line medical therapy, and which patients may require therapy escalation.

AB - BACKGROUND AND OBJECTIVES: The aim of our study is to compare the effects of sugammadex and neostigmine, used for neuromuscular blockage antagonism, on postoperative nausea and vomiting (PONV). METHODS: Our study was completed with 98 ASA I-II risk patients undergoing endotracheal intubation under general anesthesia. At the end of the surgery patients were randomly allocated into two groups given 2mgkg-1 sugammadex (Group S) or 50MUgkg-1 neostigmine plus 0.2mgkg-1 atropine (Group N). Monitoring and recording times were set as 1 hour postoperative and from 1-6, 6-12, and 12-24hours. The anti-emetic amounts administered were recorded. RESULTS: In the first postoperative hour 13 patients in Group N (27%) and 4 in Group S (8%) were observed to have nausea and/or vomiting and the difference was statistically significant (p=0.0016). During the 24hours of monitoring there was no significant difference in the incidence and severity of PONV (p>0.05), however the number of patients given ondansetron for PONV treatment in Group N was significantly higher than the number in Group S (16 in Group N, 6 in Group S, p<0.011). CONCLUSIONS: At the end of our study comparing neostigmine with sugammadex for neuromuscular blockage antagonism, we found use of sugammadex had lower incidence of PONV in the postoperative 1st hour and less anti-emetic use in 24hours of monitoring. PMID- 27692738 TI - [The effect of intra-articular levobupivacaine on shoulder cartilage at different doses-experimental study]. AB - BACKGROUND AND OBJECTIVES: In this study it was aimed to examine the histological and morphometric effects on cartilage structure of intra-articular application of levobupivacaine to the shoulder joint. METHODS: In twenty New Zealand adult male rabbits, 35 shoulders were used for the study and prepared in 5 groups of 7. These groups were defined as Groups L1, L2, L3 and L4 which were right shoulders administered with 0.25% and 0.5% levobupivacaine, Group C which were left shoulders as the control group and Groups S1 and S2 which were left shoulders administered with 0.9% saline. On the 2nd and 15th days the animals were killed, the glenohumeral joints were evaluated macroscopically then cartilage samples were taken. These samples were evaluated with Mankin score, and histomorphometrically by measuring the thickness of the cartilage between the superficial cartilage layer and the tidemark and the thickness of calcified cartilage between the tidemark and the subchondral bone. RESULTS: Macroscopically, on the 15th day the joint fluid was seen to have reduced in all the groups. After microscopic evaluation, the highest Mankin score (mean: 3.14+/ 2.1/14) was in the L4 group (15th day 0.5% levobupivacaine) and was found to be statistically significant (p<0.05). No statistically significant difference was determined between the other groups. CONCLUSIONS: Histologically, as the highest Mankin score was in the L4 group, this indicates that in a single intra-articular injection of levobupivacaine a low concentration should be selected. LEVEL OF EVIDENCE: Level 5, animal study.

PMID- 27692740 TI - Strength training for plantar fasciitis and the intrinsic foot musculature: A systematic review. AB - The aim was to critically evaluate the literature investigating strength training interventions in the treatment of plantar fasciitis and improving intrinsic foot musculature strength. A search of PubMed, CINHAL, Web of Science, SPORTSDiscus, EBSCO Academic Search Complete and PEDRO using the search terms plantar fasciitis, strength, strengthening, resistance training, intrinsic flexor foot, resistance training. Seven articles met the eligibility criteria. Methodological quality was assessed using the modified Downs and Black checklist. All articles showed moderate to high quality, however external validity was low. A comparison of the interventions highlights significant differences in strength training approaches to treating plantar fasciitis and improving intrinsic strength. It was not possible to identify the extent to which strengthening interventions for intrinsic musculature may benefit symptomatic or at risk populations to plantar fasciitis. There is limited external validity that foot exercises, toe flexion against resistance and minimalist running shoes may contribute to improved intrinsic foot musculature function. Despite no plantar fascia thickness changes being observed through high-load plantar fascia resistance training there are indications that it may aid in a reduction of pain and improvements in function. Further research should use standardised outcome measures to assess intrinsic foot musculature strength and plantar fasciitis symptoms.

PMID- 27692741 TI - Functional Imaging in Radiotherapy in the Netherlands: Availability and Impact on Clinical Practice. AB - AIMS: Functional imaging with positron emission tomography/computed tomography (PET/CT) and multiparametric magnetic resonance (mpMR) is increasingly applied for radiotherapy purposes. However, evidence and experience are still limited, and this may lead to clinically relevant differences in accessibility, interpretation and decision making. We investigated the current patterns of care in functional imaging for radiotherapy in the Netherlands in a care evaluation study. MATERIALS AND METHODS: The availability of functional imaging in radiotherapy centres in the Netherlands was evaluated; features available in >80% of academic and >80% of non-academic centres were considered standard of care. The impact of functional imaging on clinical decision making was evaluated using case questionnaires on lung, head/neck, breast and prostate cancer, with multiple choice questions on primary tumour delineation, nodal involvement, distant metastasis and incidental findings. Radiation oncologists were allowed to discuss cases in a multidisciplinary approach. Ordinal answers were evaluated by median and interquartile range (IQR) to identify the extent and variability of clinical impact; additional patterns were evaluated descriptively. RESULTS: Information was collected from 18 radiotherapy centres in the Netherlands (all except two). PET/CT was available for radiotherapy purposes to 94% of centres; 67% in the treatment position and 61% with integrated planning CT. mpMR was available to all centres; 61% in the treatment position. Technologists collaborated between departments to acquire PET/CT or mpMR for radiotherapy in 89%. All sites could carry out image registration for target definition. Functional imaging generally showed a high clinical impact (average median 4.3, scale 1-6) and good observer agreement (average IQR 1.1, scale 0-6). However, several issues resulted in ignoring functional imaging (e.g. positional discrepancies, central necrosis) or poor observer agreement (atelectasis, diagnostic discrepancies, conformation strategies). CONCLUSIONS: Access to functional imaging with PET/CT and mpMR for radiotherapy purposes, with collaborating technologists and multimodal delineation, can be considered standard of care in the Netherlands. For several specific clinical situations, the interpretation of images may benefit from further standardisation.

AB - Inductive interactions mediated by the TGF-beta and FGF-MAPK pathways are essential for specification of the germ layers and embryonic body axes during early vertebrate embryogenesis. TGF-beta and FGF ligands signal through receptor Ser/Thr and Tyr kinases, respectively, and these signaling pathways cross-talk to regulate transcription and cell behavior. The allotetraploid Xenopus laevis and its ancestral diploid Xenopus tropicalis are versatile model organisms with which to study the inductive interactions and mechanisms of these signal transduction pathways. Here we have analyzed the draft genome of X. laevis with respect to the genomic organization and differential expression of genes in the TGF-beta and FGF pathways. Genomic structure and gene expression analyses of pathway components in X. laevis revealed that genetic modulations, including deletions resulting in singletons and differential expression of homeologs, have occurred frequently among extracellular regulatory factors of the TGF-beta pathway after allotetraploidization. Moreover, differential gene expression was found for factors regulating various cellular responses including co-receptors, decoy receptors, and intracellular negative regulators in both the TGF-beta and FGF MAPK pathways. We summarize the patterns of genetic alterations in the allotetraploid frog X. laevis and discuss the importance of these changes with regard to developmental processes.

PMID- 27692748 TI - [Measurement of fractional flow reserve in patients with severe aortic stenosis: A valid test?] AB - A 54-year-old woman was hospitalized for an acute pulmonary oedema revealing a severe aortic stenosis (AS) associated with an aortic aneurysm and a left ventricular hypertrophy (LVH). The coronary angiography found an equivocal left main lesion. Fractional flow reserve (FFR) showed hemodynamic significance (FFR=0.78) and optical coherence tomography confirmed this result with a minimal lumen area of 4.9mm2. FFR-guided percutaneous intervention is reported to improve outcome in patients with stable coronary disease. However, only few data are available in cases of AS. In this condition, secondary LVH is associated with microcirculatory dysfunction, which interferes with optimal hyperemia. An elevated right atrial pressure could also modify FFR measurement. This risk of underestimation of a coronary lesion in patients with severe AS has to be taken into consideration in clinical practice.

In this report, we present the case of a 64 year-old man with a history of ischemic heart disease who underwent a preoperative DSE; during the test, we witnessed a striking acute constitution of an intense prethrombotic state with almost a formation of a highly mobile massive thrombus adjacent to the infero-apical segment spontaneously resolving few minutes after the end of the test. PMID- 27692751 TI - [Cardiac rehabilitation in "sports" patients]. AB - BACKGROUND: Cardiac rehabilitation (CR) addresses for the greater part a middle aged sedentary population. Nevertheless, some patients referred in CR are active or sportive, and care for these patients is less known. AIM OF THE STUDY: To compare the results of CR between a little or not active population and an active or athletic population. PATIENTS AND METHODS: Every patient referred in a CR department in Loire-Atlantique between 2010 and 2016 were included either in the group 1 (sedentary or little active) or in the group 2 (at least once a week physical training).) RESULTS: Among 2916 patients included, 2288 patients did two exercise tests, the functional capacity in the group 1 (n=2117) increased from 4.7+/-1.2 to 5.6+/-1.3 METs versus 6.5+/-1.7 to 7.6+/-1.8 METs in the group 2 (n=171), the gain was similar in both groups from 19+/-13% to 18+/-14% (P=0.16). The 6minutes Walking Test respectively increased from 445+/-91 to 517+/-89 versus 518+/-87 to 603+/-73 meters with a gain of 18+/-18 versus 18+/-16% (P=0.93). The prognosis is yet to be best in the group 2 in accordance to a best maximal functional capacity (P<0.01). CONCLUSION: Cardiac rehabilitation is useful in active or athletic patients and should be prescribed based on the current recommendations.

AB - The acute heart failure generates a very important number of hospitalizations for a high cost. A recent reflection on optimizing its management is ongoing, based on the fastest management in the emergency department, with a distinction between which patient should remain and who returns at home, and under what conditions, allowing to limit the number of hospitalizations. It will require a reorganization of emergency department and updating of decision algorithms and new guidelines of care.

AB - Peptide receptor therapy with 177Lu-labelled somatostatin analogues is a promising tool in the management of patients with inoperable or metastasized neuroendocrine tumours. The aim of this work was to perform accurate activity quantification of 177Lu in complex anthropomorphic geometry using advanced correction algorithms. Acquisitions were performed on the higher 177Lu photopeak (208keV) using a Philips IRIX gamma camera provided with medium-energy collimators. System calibration was performed using a 16mL Jaszczak sphere surrounded by non-radioactive water. Attenuation correction was performed using MU-maps derived from CT data, while scatter and septal penetration corrections were performed using the transmission-dependent convolution-subtraction method. SPECT acquisitions were finally corrected for dead time and partial volume effects. Image analysis was performed using the commercial QSPECT software. The quantitative SPECT approach was validated on an anthropomorphic phantom provided with a home-made insert simulating a hepatic lesion. Quantitative accuracy was studied using three tumour-to-background activity concentration ratios (6:1, 9:1, 14:1). For all acquisitions, the recovered total activity was within 12% of the calibrated activity both in the background region and in the tumour. Using a 6:1 tumour-to-background ratio the recovered total activity was within 2% in the tumour and within 5% in the background. Partial volume effects, if not properly accounted for, can lead to significant activity underestimations in clinical conditions. In conclusion, accurate activity quantification of 177Lu can be obtained if activity measurements are performed with equipment traceable to primary standards, advanced correction algorithms are used and acquisitions are performed at the 208keV photopeak using medium-energy collimators. PMID- 27692754 TI - Validation of Bayesian analysis of compartmental kinetic models in medical imaging. AB - INTRODUCTION: Kinetic compartmental analysis is frequently used to compute physiologically relevant quantitative values from time series of images. In this paper, a new approach based on Bayesian analysis to obtain information about these parameters is presented and validated. MATERIALS AND METHODS: The closed form of the posterior distribution of kinetic parameters is derived with a hierarchical prior to model the standard deviation of normally distributed noise. Markov chain Monte Carlo methods are used for numerical estimation of the posterior distribution. Computer simulations of the kinetics of F18 fluorodeoxyglucose (FDG) are used to demonstrate drawing statistical inferences about kinetic parameters and to validate the theory and implementation. Additionally, point estimates of kinetic parameters and covariance of those estimates are determined using the classical non-linear least squares approach. RESULTS AND DISCUSSION: Posteriors obtained using methods proposed in this work are accurate as no significant deviation from the expected shape of the posterior was found (one-sided P>0.08). It is demonstrated that the results obtained by the standard non-linear least-square methods fail to provide accurate estimation of uncertainty for the same data set (P<0.0001). CONCLUSIONS: The results of this work validate new methods for a computer simulations of FDG kinetics. Results show that in situations where the classical approach fails in accurate estimation of uncertainty, Bayesian estimation provides an accurate information about the uncertainties in the parameters. Although a particular example of FDG kinetics was used in the paper, the methods can be extended for different pharmaceuticals and imaging modalities. PMID- 27692755 TI - Apnea After Low-Dose Ketamine Sedation During Attempted Delayed Sequence Intubation. AB - Some patients are agitated and unable to tolerate conventional preoxygenation methods, including face mask oxygen or noninvasive positive-pressure ventilation. Sedation with ketamine for preoxygenation, also known as delayed sequence intubation, is a technique that can be used to achieve preoxygenation in this patient population. No complications of delayed sequence intubation have previously been reported. A 60-year-old woman presented with acute hypoxic respiratory failure. Despite application of high-flow oxygen (60 L/min) with a nonrebreather face mask, her oxygen saturation remained at 93%. She would not accept a noninvasive positive-pressure ventilation mask, although she remained alert, with vigorous respiratory effort. She received 25 mg of intravenous ketamine (0.31 mg/kg) to allow application of noninvasive positive-pressure ventilation. One minute after receiving ketamine, she developed apnea; bag-valve mask ventilation was initiated, and she received succinylcholine and etomidate and was intubated on the first attempt, without complication. She had no respiratory effort between the onset of apnea and pharmacologic paralysis. Apnea can occur in critically ill patients who receive ketamine to facilitate preoxygenation. Sedation remains a valuable technique to enable optimal preoxygenation in agitated patients; however, clinicians should not perform this technique lightly and should be prepared to secure the patient's airway immediately.

AB - INTRODUCTION: Although spatial examination of mortality and morbidity is becoming more common in health studies, the investigation of suicide death clusters within the neighborhood context is underutilized. The purpose of this ecological study is to detect high- and low-risk clusters of suicide deaths in Florida and determine which neighborhood characteristics distinguish clusters from non clusters. METHODS: The scan statistic method was used to detect overall clusters of completed suicides in Florida from 2001 to 2010. Regression analysis was used to investigate the association of neighborhood characteristics with identified clusters. All data synthesis and statistical analyses were conducted in 2015. RESULTS: Twenty-four high-risk and 25 low-risk clusters were identified. The risk of suicide was up to 3.4 times higher in high-risk clusters than in areas outside of clusters (relative risk ranged from 1.36 to 3.44, p<=0.05). Low-risk clusters were associated with 30%-94% decreased risk of suicide (relative risk ranged from 0.06 to 0.70, p<=0.05). Areas with high levels of elderly concentration and household singularity were more likely to be in high-risk clusters, whereas areas with higher economic deprivation and residential density were more likely to be in low-risk clusters. CONCLUSIONS: This study identified general suicide patterns across space in the state of Florida and described the characteristics of those areas.

AB - INTRODUCTION: Hospitalization for acute myocardial infarction (AMI) is an opportune time to counsel smokers to quit. Studies have demonstrated lower short term mortality for counseled versus non-counseled smokers; yet, little is known about the long-term survival benefits of post-AMI smoking-cessation counseling (SCC). METHODS: Data from the Cooperative Cardiovascular Project, a prospective cohort study of elderly patients with AMI between 1994 and 1996 with >17 years of follow-up, were used to evaluate the association of SCC with short- and long-term mortality in smokers with AMI. Life expectancy and years of potential life gained were used to quantify the long-term survival benefits of SCC. Cox proportional hazards models with exponential extrapolation were used to estimate life expectancy. RESULTS: The analysis included 13,815 smokers, of whom 5,695 (41.2%) received SCC. Non-counseled smokers had higher crude mortality than counseled smokers over all 17 years of follow-up. After adjustment for patient and hospital characteristics, SCC was associated with a 22.6% lower 30-day mortality and a 7.5% lower mortality over 17 years. These survival differences produced higher life expectancy estimates for counseled smokers than non-counseled smokers at all ages, which resulted in average gains in life years of 0.13 (95% CI=-0.31, 0.56) to 0.58 (95% CI=0.25, 0.91) years, with the largest gains observed in older smokers. CONCLUSIONS: SCC is associated with longer life expectancy and gains in life years in elderly smokers with AMI, supporting the importance of post-AMI counseling efforts. PMID- 27692759 TI - Reality or singular pipe dream? PMID- 27692758 TI - Thoracic endovascular aortic repair (TEVAR) in proximal (type A) aortic dissection: Ready for a broader application? AB - OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) has demonstrated encouraging results and is gaining increasing acceptance as a treatment option for aortic aneurysms and dissections. Yet, its role in managing proximal aortic pathologies is unknown-this is important because in proximal (Stanford type A) aortic dissections, 10% to 30% are not accepted for surgery and 30% to 50% are technically amenable for TEVAR. We describe our case series of type A aortic dissections treated by using TEVAR. METHODS: Between year 2009 and 2016, 12 patients with acute, subacute, or chronic type A aortic dissection with the proximal entry tear located between the coronaries and brachiocephalic artery were treated with TEVAR at 3 centers. Various stent-graft configurations were used to seal the proximal entry tear in the ascending aorta under rapid pacing. RESULTS: A total of 12 patients (9 male, 3 female), mean age 81 +/- 7 years, EuroSCORE II 9.1 +/- 4.5, underwent TEVAR for the treatment of type A aortic dissection. Procedural success was achieved in 11 of 12 patients (91.7%). There was 1 minor stroke and 1 intraprocedural death. No additional deaths were reported at 30 days. At 36 months, there were 4 further deaths (all from nonaortic causes). The mean survival of these 4 deceased was 23 months (range 15 36 months). Follow-up computed tomography demonstrated favorable aortic remodeling. CONCLUSIONS: TEVAR is feasible and reveals promising early results in selected patients with type A aortic dissection who are poor candidates for surgical repair. The current iteration of stent-graft technology, however, needs to be adapted to features specific to the ascending aorta.

AB - OBJECTIVE: We are developing a transapical-to-aorta double lumen cannula (TAA DLC) for a less-invasive/more dependable neonatal left ventricular assist device. METHODS: The 18-Fr TAA DLC prototypes were bench tested and evaluated for 6 hours in neonate lambs (n = 6, 7.7-10 kg). The cardiac apex was exposed through a left anterolateral thoracotomy through the sixth intercostal space. The TAA DLC was inserted through a mattress stitch on apex, passing LV-aortic valve, into the ascending aorta with insertion/deployment guided by pressure waveform. The DLC was connected to blood pump. Cardiac output and aortic root blood flow were measured with perivascular flow sensors. Activated clotting time was maintained at 180-250 seconds. RESULTS: The DLC pumped up to 1.8 L/min flow against 63 mm Hg drainage pressure and 145 mm Hg infusion pressure in bench testing. In all lambs, the DLC was inserted/deployed properly within 1 minute on the first attempt. Pumping flow was maintained at 1.2-1.3 L/min. Systolic arterial pressure decreased and diastolic arterial pressure/mean arterial pressure increased, indicating decreased afterload and increased perfusion pressure. Left ventricular end-diastolic pressure decreased from 13 +/- 1 mm Hg to 6 +/- 2 mm Hg, indicating decreased preload. Aortic root backward flow was 2.4% +/- 0.6% without DLC and 3.5% +/- 0.8% of cardiac output with DLC, indicating no significant DLC-induced aortic valve regurgitation. After 6 hours, free hemoglobin was <5 mg/dL with hemoglobin/platelets unchanged. No significant thrombus was found in pumps/DLCs. No trauma was found in LV, aortic valve, and aorta. CONCLUSIONS: Our TAA DLC based neonate left ventricular assist device efficiently unloaded the LV in lambs. PMID- 27692764 TI - Just when you thought you'd seen everything.

PMID- 27692766 TI - Pulmonary flow study predicts survival in pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries. AB - BACKGROUND: We hypothesized that mean pulmonary artery pressure (PAP) detected on a pulmonary flow study may predict medium-term survival and right ventricular systolic pressure (RVSP) in patients with pulmonary atresia (PA), ventricular septal defect (VSD), and major aortopulmonary collateral arteries (MAPCAs). METHODS: Fifty patients with PA/VSD/MAPCAs underwent unifocalization between 2000 and 2013, and 40 of these patients had a pulmonary flow study since 2003. Predictability of the mean PAP on VSD status, medium-term survival, reintervention, and RVSP were analyzed. RESULTS: Forty-seven of the 50 patients (94%) had complete unifocalization at a median age of 11 months (range, 1-194 months), and 37 patients (74%) achieved VSD closure. Among the 40 patients who underwent a pulmonary flow study, the VSD was closed in 34 (85%), with salvage VSD fenestration in 4 (10%), and was intentionally left open in 6 (15%). Survival was 85.5% at 1 year and 78.5% at 5 years. A mean PAP >=25 mm Hg was associated with worse survival (P = .011). Cox regression analysis identified a mean PAP >=25 mm Hg as the sole predictor for death (P = .037). Patients with an open VSD had an increased risk of reoperation (P = .001) and pulmonary artery reintervention (P = .010), and had a trend toward increased risk of death (P = .059), compared with those with a closed VSD. CONCLUSIONS: PAP obtained from the intraoperative pulmonary flow study is associated with medium-term survival and late RVSP in patients with PA/VSD/MAPCAs. VSD closure for patients with a mean PAP >=25 mm Hg on a flow study is considered high risk, and sensible judgment and a low threshold for VSD fenestration are required. PMID- 27692768 TI - Concept of an expandable cardiac valve for surgical implantation in infants and children. AB - BACKGROUND: Options for cardiac valve replacement in children are limited to fixed-diameter prostheses that do not accommodate for somatic growth. An externally stented bovine jugular vein graft has been modified for surgical valve replacement in pediatric patients, with the intention of subsequent valve expansion in the catheterization laboratory as the child grows. METHODS: Pediatric patients at a single institution who underwent surgical implantation of an expandable bovine jugular vein valve between 2010 and 2014 were reviewed retrospectively. Forty-two patients underwent implantation at median age of 10 months (range, 3 weeks to 5.8 years) in aortic, mitral, pulmonary, or tricuspid positions. Numerous techniques for valve modification and implantation were used. RESULTS: The valve was competent with low gradient acutely postoperatively in all patients. Eight patients experienced central or paravalvular deterioration, and 7 required reoperation for valve-related adverse outcomes. Twenty patients underwent at least one previous valve repair or replacement. Twenty patients underwent 32 episodes of catheter-based balloon expansion of the valve, exhibiting a significant decrease in median gradient from 12 mm Hg to 8 mm Hg (P < .001) with no significant increase in grade of regurgitation. At 12 months after implantation, Kaplan-Meier analysis indicated that 88% would be expected to be free from reoperation (95% confidence interval, 78%-98%). A total of 6 deaths occurred, 3 before discharge and 3 late. CONCLUSIONS: A surgically implanted externally reinforced bovine jugular vein demonstrates acceptable short-term function and is amenable to catheter-based enlargement as the child grows. Modification of valve design and implantation techniques are necessary to reduce perivalvular complications.

AB - In March 2010, Brazil introduced the 10-valent pneumococcal conjugate vaccine (PCV10) in the routine infant immunization program using a 4-dose schedule and catch-up for children <23months. We investigated PCV10 effect on nasopharyngeal carriage with vaccine-type Streptococcus pneumoniae (Spn) and non-typeable Haemophilus influenzae (NTHi) among children in Sao Paulo city. Cross-sectional surveys were conducted in 2010 (baseline) and 2013 (post-PCV10). Healthy PCV naive children aged 12-23months were recruited from primary health centers during immunization campaigns. Nasopharyngeal swabs were collected and tested for Hi; for Spn, all baseline and a stratified random sample of 400 post-PCV10 swabs were tested. We compared vaccine-type Spn and NTHi carriage prevalence pre-/post PCV10, and used logistic regression to estimate PCV10 effectiveness (1-adjusted odds ratio*100%). Overall 501 children were included in the baseline and 1167 in the post-PCV10 survey (including 400 tested for Spn). Spn was detected in 40.3% of children at baseline and 48.8% post-PCV10; PCV10 serotypes were found in 19.8% and 1.8% respectively, representing a decline of 90.9% (p<0.0001). Carriage of vaccine-related serotypes increased (10.8-21.0%, p<0.0001), driven primarily by a rise in serotype 6C (1.8-11.2%, p<0.0001); carriage of serotypes 6A and 19A did not significantly change. PCV10 effectiveness (4 doses) against vaccine-type carriage was 97.3% (95% confidence interval 88.7-99.3). NTHi prevalence increased from 26.0% (130/501) to 43.6% (509/1167, p<0.0001); PCV10 vaccination seemed significantly associated with NTHi carriage, even after adjusting for other known risk factors. Carriage with PCV10 serotypes among toddlers declined dramatically following PCV10 introduction in Sao Paulo, Brazil. No protection of PCV10 against NTHi was observed. Our findings contribute to a growing body of evidence of PCV10 impact on vaccine-type carriage and highlight the importance of PCV10 as a tool to reduce the burden of pneumococcal disease in Brazil and globally. PMID- 27692771 TI - Identification of Plasmodium falciparum reticulocyte binding protein homologue 5 interacting protein, PfRipr, as a highly conserved blood-stage malaria vaccine candidate. AB - Genetic variability in Plasmodium falciparum malaria parasites hampers current malaria vaccine development efforts. Here, we hypothesize that to address the impact of genetic variability on vaccine efficacy in clinical trials, conserved antigen targets should be selected to achieve robust host immunity across multiple falciparum strains. Therefore, suitable vaccine antigens should be assessed for levels of polymorphism and genetic diversity. Using a total of one hundred and two clinical isolates from a region of high malaria transmission in Uganda, we analyzed extent of polymorphism and genetic diversity in four recently reported novel blood-stage malaria vaccine candidate proteins: Rh5 interacting protein (PfRipr), GPI anchored micronemal antigen (PfGAMA), rhoptry-associated leucine zipper-like protein 1 (PfRALP1) and Duffy binding-like merozoite surface protein 1 (PfMSPDBL1). In addition, utilizing the wheat germ cell-free system, we expressed recombinant proteins for the four candidates based on P. falciparum laboratory strain 3D7 sequences, immunized rabbits to obtain specific antibodies (Abs) and performed functional growth inhibition assay (GIA). The GIA activity of the raised Abs was demonstrated using both homologous 3D7 and heterologous FVO strains in vitro. Both pfripr and pfralp1 are less polymorphic but the latter is comparatively more diverse, with varied number of regions having insertions and deletions, asparagine and 6-mer repeats in the coding sequences. Pfgama and pfmspdbl1 are polymorphic and genetically diverse among the isolates with antibodies against the 3D7-based recombinant PfGAMA and PfMSPDBL1 inhibiting merozoite invasion only in the 3D7 but not FVO strain. Moreover, although Abs against the 3D7-based recombinant PfRipr and PfRALP1 proteins potently inhibited merozoite invasion of both 3D7 and FVO, the GIA activity of anti-PfRipr was much higher than that of anti-PfRALP1. Thus, PfRipr is regarded as a promising blood stage vaccine candidate for next-generation vaccines against P. falciparum. PMID- 27692772 TI - Assessing strategies for increasing urban routine immunization coverage of childhood vaccines in low and middle-income countries: A systematic review of peer-reviewed literature. AB - INTRODUCTION: Immunization programs in developing countries increasingly face challenges to ensure equitable delivery of services within cities where rapid urban growth can result in informal settlements, poor living conditions, and heterogeneous populations. A number of strategies have been utilized in developing countries to ensure high community demand and equitable availability of urban immunization services; however, a synthesis of the literature on these strategies has not previously been undertaken. METHODS: We reviewed articles published in English in peer-reviewed journals between 1990 and 2013 that assessed interventions for improving routine immunization coverage in urban areas in low- and middle-income countries. We categorized the intervention in each study into one of three groups: (1) interventions aiming to increase utilization of immunization services; (2) interventions aiming to improve availability of immunization services by healthcare providers, or (3) combined availability and utilization interventions. We summarized the main quantitative outcomes from each study and effective practices from each intervention category. RESULTS: Fifteen studies were identified; 87% from the African, Eastern Mediterranean and Southeast Asian regions of the World Health Organization (WHO). Six studies were randomized controlled trials, eight were pre- and post-intervention evaluations, and one was a cross-sectional study. Four described interventions designed to improve availability of routine immunization services, six studies described interventions that aimed to increase utilization, and five studies aiming to improve both availability and utilization of services. All studies reported positive change in their primary outcome indicator, although seven different primary outcomes indicators were used across studies. Studies varied considerably with respect to the type of intervention assessed, study design, and length of intervention assessment. CONCLUSION: Few studies have assessed interventions designed explicitly for the unique challenges facing immunization programs in urban areas. Further research on sustainability, scalability, and cost effectiveness of interventions is needed to fill this gap. PMID- 27692774 TI - Can Sentinel Lymph Node Biopsy Be Spared in Papillary Carcinoma of the Breast? AB - BACKGROUND: Papillary carcinoma (PC) of the breast represents ~0.5% of all newly diagnosed cases of breast cancer and usually has an indolent course. The current data suggest lack of a consensus in the surgical management of this disease. Because patients can occasionally develop metastatic disease, sentinel lymph node (SLN) biopsy is often performed during surgery. MATERIALS AND METHODS: In the present study, we retrospectively evaluated the histologic characteristics of 99 cases of PC with or without associated frank invasive carcinoma, including 43 encapsulated or intracystic PCs, 24 solid PCs, and 32 intraductal PCs, and correlated these with the incidence of nodal metastasis. RESULTS: Of the 99 cases, 64 were tumor stage Tis (noninvasive), 5 were T1 microinvasive, 17 T1a, 5 T1b, 5 T1c, and 3 were T2. A total of 37 patients (37%) underwent axillary staging, including 31 SLN biopsies and 6 axillary dissections. Only 1 patient (2.7%) with noninvasive solid PC had evidence of nodal metastasis. Follow-up information was available for 81 patients, with a mean follow-up period of 4.9 years (range, 1-13 years). Two local recurrences, no distant metastases, and no disease-related deaths were recorded. CONCLUSION: PC rarely involves the lymph nodes even in tumors with an associated frank invasive component, and the overall prognosis and long-term survival is excellent. We propose that evaluation of the SLN should not be routinely indicated for patients with PC treated by local control lumpectomy. PMID- 27692773 TI - Brain Metastasis Prediction by Transcriptomic Profiling in Triple-Negative Breast Cancer. AB - BACKGROUND: Triple-negative breast cancer (TNBC) lacks expression of steroid hormone receptors (estrogen receptor alpha and progesterone) and epidermal growth factor receptor type 2. This phenotype shows high metastatic potential, with particular predilection to lungs and brain. Determination of TNBC transcriptomic profiles associated with high risk of brain metastasis (BM) might identify patients requiring alternative, more aggressive, or specific preventive and therapeutic approaches. PATIENTS AND METHODS: Using a cDNA-mediated annealing, selection, extension, and ligation assay, we investigated expression of 29,369 gene transcripts in primary TNBC tumor samples from 119 patients-71 in discovery cohort A and 48 in independent cohort B-that included best discriminating genes. Expression of mRNA was correlated with the occurrence of symptomatic BM. RESULTS: In cohort A, the difference at the noncorrected P < .005 was found for 64 transcripts (P = .23 for global test), but none showed significant difference at a preset level of false-discovery rate of < 10%. Of the 30 transcripts with the largest differences between patients with and without BM in cohort A, none was significantly associated with BM in cohort B. CONCLUSION: Analysis based on the primary tumor gene transcripts alone is unlikely to predict BM development in advanced TNBC. Despite its negative findings, the study adds to the knowledge on the biology of TNBC and paves the way for future projects using more advanced molecular assays. PMID- 27692775 TI - Rift Valley fever: still an emerging infection after 3500 years. PMID- 27692776 TI - Association of Rift Valley fever virus infection with miscarriage in Sudanese women: a cross-sectional study. AB - BACKGROUND: Rift Valley fever virus is an emerging mosquito-borne virus that causes infections in animals and human beings in Africa and the Arabian Peninsula. Outbreaks of Rift Valley fever lead to mass abortions in livestock, but such abortions have not been identified in human beings. Our aim was to investigate the cause of miscarriages in febrile pregnant women in an area endemic for Rift Valley fever. METHODS: Pregnant women with fever of unknown origin who attended the governmental hospital of Port Sudan, Sudan, between June 30, 2011, and Nov 17, 2012, were sampled at admission and included in this cross sectional study. Medical records were retrieved and haematological tests were done on patient samples. Presence of viral RNA as well as antibodies against a variety of viruses were analysed. Any association of viral infections, symptoms, and laboratory parameters to pregnancy outcome was investigated using Pearson's chi2 test. FINDINGS: Of 130 pregnant women with febrile disease, 28 were infected with Rift Valley fever virus and 31 with chikungunya virus, with typical clinical and laboratory findings for the infection in question. 15 (54%) of 28 women with an acute Rift Valley fever virus infection had miscarriages compared with 12 (12%) of 102 women negative for Rift Valley fever virus (p<0.0001). In a multiple logistic regression analysis, adjusting for age, haemorrhagic disease, and chikungunya virus infection, an acute Rift Valley fever virus infection was an independent predictor of having a miscarriage (odds ratio 7.4, 95% CI 2.7-20.1; p<0.0001). INTERPRETATION: This study is the first to show an association between infection with Rift Valley fever virus and miscarriage in pregnant women. Further studies are warranted to investigate the possible mechanisms. Our findings have implications for implementation of preventive measures, and evidence-based information to the public in endemic countries should be strongly recommended during Rift Valley fever outbreaks.

PMID- 27692778 TI - Definition and classification of chyle leak after pancreatic operation: A consensus statement by the International Study Group on Pancreatic Surgery. AB - BACKGROUND: Recent literature suggests that chyle leak may complicate up to 10% of pancreatic resections. Treatment depends on its severity, which may include chylous ascites. No international consensus definition or grading system of chyle leak currently is available. METHODS: The International Study Group on Pancreatic Surgery, an international panel of pancreatic surgeons working in well-known, high-volume centers, reviewed the literature and worked together to establish a consensus on the definition and classification of chyle leak after pancreatic operation. RESULTS: Chyle leak was defined as output of milky-colored fluid from a drain, drain site, or wound on or after postoperative day 3, with a triglyceride content >=110 mg/dL (>=1.2 mmol/L). Three different grades of severity were defined according to the management needed: grade A, no specific intervention other than oral dietary restrictions; grade B, prolongation of hospital stay, nasoenteral nutrition with dietary restriction, total parenteral nutrition, octreotide, maintenance of surgical drains, or placement of new percutaneous drains; and grade C, need for other more invasive in-hospital treatment, intensive care unit admission, or mortality. CONCLUSION: This classification and grading system for chyle leak after pancreatic resection allows for comparison of outcomes between series. As with the other the International Study Group on Pancreatic Surgery consensus statements, this classification should facilitate communication and evaluation of different approaches to the prevention and treatment of this complication. PMID- 27692779 TI - Incidence and characteristics of chemical burns. AB - OBJECTIVES: Chemical burns can lead to serious health outcomes. Previous studies about chemical burns have been performed based on burn center data so these studies have provided limited information about the incidence of chemical burns at the national level. The aim of this study was to evaluate the incidence and characteristics of chemical burns using nationwide databases. METHODS: A cohort representing the Korean population, which was established using a national health insurance database, and a nationwide workers' compensation database were used to evaluate the incidence and characteristics of chemical burns. Characteristics of the affected body region, depth of burns, industry, task, and causative agents were analyzed from two databases. The incidence of chemical burns was calculated according to employment status. RESULTS: The most common regions involving chemical burns with hospital visits were the skin followed by the eyes. For skin lesions, the hands and wrists were the most commonly affected regions. Second degree burns were the most common in terms of depth of skin lesions. The hospital visit incidence was 1.96 per 10,000 person-year in the general population. The compensated chemical burns incidence was 0.17 per 10,000 person-year. Employees and the self-employed showed a significantly increased risk of chemical burns undergoing hospital visits compared to their dependents. CONCLUSION: Chemical burns on the skin and eyes are almost equally prevalent. The working environment was associated with increased risk of chemical burns. Our results may aid in estimating the size of the problem and prioritizing prevention of chemical burns. PMID- 27692780 TI - Upon admission coagulation and platelet function in patients with thermal and electrical injuries. AB - RATIONAL: There has been increased focus on hemostatic potential and function in the initial assessment of the patient with traumatic injuries, that not been extensively studied in patients with burns. We proposed to determine the hemostatic potential of patients with burns upon admission to the emergency department and contrasted their condition with that of healthy controls and patients with other traumatic injuries. In addition we assessed differences due to thermal versus electrical injury and evaluated the effect of burn size. METHODS: This is a patient based prospective observational study conducted with delayed consented. Subjects at the highest level of trauma activation upon admission to the ED had a blood sample collected for research purposes and were subsequently consented. Hemostatic potential was measured by rapid thromelastography (r-TEG(r)), thrombin generation by calibrated automated thrombogram (CAT) and platelet function by Multiplate(r) using five activators. Burn subjects were compared to subjects with other traumatic injuries and controls. Within the burn subjects additional analysis compared mechanism (thermal vs. electrical) and burn size. Values are medians (IQR). RESULTS: Two hundred and eighty two trauma patients (with burns n=40, 14%) and 27 controls were enrolled. Upon admission, compared to controls, subjects with burns or trauma were hyper-coagulable based on r-TEG and CAT, with increased rates of clot formation and thrombin generation. There were no differences in burns compared to other traumatic injuries. The presence of hyper-coagulation did not appear to be related to the type of burn or the percentage of total body surface area involved. Employing previous defined cut points for R-TEG driven therapeutic interventions burn patients had similar rates of hyper- and hypo-coagulation noted in patients with traumatic injuries. CONCLUSION: Upon admission patients with burns are in a hyper-coagulable state similar to that of other trauma patients. Employing demonstrated cut points of hemostatic potential in trauma patients associated with increased risk of poor outcomes demonstrated the incidence in burn patients to be similar, suggesting that these values could be used in the early assessment of the patient with burns to guide treatment interventions. PMID- 27692781 TI - Long-term outcome of patients with very small coronary artery disease: A comparison of drug-eluting and bare metal stents. AB - BACKGROUND: Among patients with very small vessel disease and chronic kidney disease (CKD), the comparative efficacy of bare metal stents (BMSs) versus drug eluting stents (DESs) is not frequently addressed. This study aimed to evaluate the long-term outcomes of patients with very small vessel disease managed with percutaneous coronary intervention. METHODS: Our study included 158 consecutive patients undergoing percutaneous coronary intervention from January 2003 to December 2013. The primary end points were cardiovascular death and target vessel failure, which consisted of cardiovascular death, target vessel-related myocardial infarction, and ischemia-driven target vessel revascularization. RESULTS: BMSs were used in 37 patients, while DESs were utilized in 121 patients. During the mean follow-up period of 2.7 +/- 2.2 years (median 2.1 years; interquartile range, 1.3-4.2 years), the target vessel failure rate was 48.6% versus 28.1% (BMS vs. DES, p = 0.020) and the cardiovascular death rate was 27% versus 18.2% (BMS vs. DES, p = 0.241). The use of a DES (hazard ratio: 0.44, 95% confidence interval: 0.24-0.79, p = 0.006) remained the most significant predictor of target vessel failure after multivariate analysis. In CKD subgroup analysis, the benefit of a 2.25 mm DES was evident only in the subgroup with CKD, but such a benefit disappeared in those without CKD. CONCLUSION: Compared with BMSs, implantation of DESs in a patient population with very small vessel disease effectively reduced target vessel failure. However, the beneficial effects of DESs appeared to be evident only in the subgroup with CKD. PMID- 27692782 TI - Preoperative Anxiety and Depression Correlate With Dissatisfaction After Total Knee Arthroplasty: A Prospective Longitudinal Cohort Study of 186 Patients, With 4-Year Follow-Up. AB - BACKGROUND: After more than 4 decades experience of total knee arthroplasty (TKA), there is still a group of patients who are not satisfied with the outcome. In spite of the improvement of many aspects around the procedure, for unexplainable reasons, patient dissatisfaction is still approximately the same. We conducted this study to analyze correlations between preoperative psychological aspects and dissatisfaction after TKA. METHODS: A total of 186 patients were operated with a primary TKA. Patients filled out the Hospital Anxiety and Depression Scale, Visual Analog Pain Scale (0-100), and Knee injury and Osteoarthritis Outcome Score preoperatively and 4 years postoperatively. Four years postoperatively, the patients also scored their satisfaction degree with the outcome of the surgery. RESULTS: Of 186 patients, 27 (15%) reported that they were dissatisfied or uncertain with the result of their TKA 4 years postoperatively. Sixteen of those 27 patients had reported anxiety/depression preoperatively compared with 11 of 159 (7%) in the satisfied or very satisfied groups. Patients with preoperative anxiety or depression had more than 6 times higher risk to be dissatisfied compared with patients with no anxiety or depression (P < .001). Patients with deep prosthetic infection had 3 times higher risk to be dissatisfied with the operation outcome (P = .03). Dissatisfied patients had 1-day longer hospital stay compared with the satisfied group (P < .001). CONCLUSION: Preoperative anxiety and/or depression is an import predictor for dissatisfaction after TKA. Psychological assessment and treatment preoperatively might improve degree of satisfaction. PMID- 27692783 TI - The Role of Patient Characteristics on the Choice of Unicompartmental versus Total Knee Arthroplasty in Patients With Medial Osteoarthritis. AB - BACKGROUND: Medial unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) are both viable treatment options for medial osteoarthritis (OA). However, it remains unclear when to choose for which arthroplasty treatment. Goals of this study were therefore to (1) compare outcomes after both treatments and (2) assess which treatment has superior outcomes in different patient subgroups. METHODS: In this retrospective cohort study, 166 patients received the RESTORIS MCK Medial UKA and 63 patients the Vanguard TKA and were radiographically matched on isolated medial OA. Western Ontario and McMaster Universities Arthritis Index scores were collected preoperatively and postoperatively (mean: 3.0 years, range: 2.0-5.0 years). RESULTS: Preoperatively, no differences were observed, but medial UKA patients reported better functional outcomes than TKA (89.7 +/- 13.6 vs 81.2 +/- 18.0, P = .001) at follow-up.Better functional outcomes were noted after medial UKA in patients younger than age 70 years (89.5 +/- 14.2 vs 78.6 +/- 20.0, P = .001), with body mass index below 30 (90.3 +/- 11.4 vs 83.6 +/- 14.9, P = .005), with body mass index above 30 (88.3 +/- 17.5 vs 78.8 +/- 21.0, P = .034) and in females (90.6 +/- 11.0 vs 78.1 +/- 19.4, P = .001) when compared with TKA. No differences were found in males and older patients between both arthroplasties. CONCLUSION: Superior functional outcomes were noted after medial UKA over TKA in patients presenting with medial OA with these prostheses. Subgroup analyses suggest that medial UKA is the preferred treatment in younger patients and females while no differences were noted in older patients and males after medial UKA and TKA. This might help the orthopedic surgeon in individualizing arthroplasty treatment for patients with medial OA. PMID- 27692784 TI - Tibial Tubercle Osteotomy in Revision Knee Arthroplasty. AB - BACKGROUND: Obtaining adequate exposure while maintaining the integrity of the extensor mechanism is crucial to the success of revision knee arthroplasty. This is particularly important in infected cases where staged procedures are necessary. While the use of a long, tibial tubercle osteotomy (TTO) is an established method to improve exposure, controversy still exists concerning complication rates and sequential use. METHODS: Forty-two TTOs were performed in revision knee arthroplasties between 2009 and 2015. Follow-up period ranged from 3 to 24 months. Twenty-four TTOs were performed for single-stage revisions, and 18 TTOs were performed for 2-stage infected revisions. In infected cases, the initial osteotomy was left unfixed between stages. Screws were used to fix the osteotomy flap in all cases. RESULTS: All osteotomies united with no fractures, and there were no extensor lags. Minor proximal migration was noted in 1 case, and refixation was required in another. Greater range of motion (ROM) and improved Oxford Knee Scores were achieved in the single-stage revision group. In the infected 2-stage group, sequential use did not decrease union rates, and infection was eradicated in 14 of the 16 knees (88%). CONCLUSION: We conclude that TTO is a safe and reproducible procedure when exposure needs improving in revision knee arthroplasty. In 2-stage revisions, sequential osteotomies do not decrease union rates, and leaving the osteotomy unfixed after the first stage does not cause any adverse issues. PMID- 27692785 TI - Reduced health care-associated infections in an acute care community hospital using a combination of self-disinfecting copper-impregnated composite hard surfaces and linens. AB - BACKGROUND: The purpose of this study was to determine the effectiveness of copper-impregnated composite hard surfaces and linens in an acute care hospital to reduce health care-associated infections (HAIs). METHODS: We performed a quasiexperimental study with a control group, assessing development of HAIs due to multidrug resistant organisms (MDROs) and Clostridium difficile in the acute care units of a community hospital following the replacement of a 1970s-era clinical wing with a new wing outfitted with copper-impregnated composite hard surfaces and linens. RESULTS: The study was conducted over a 25.5-month time period that included a 3.5-month washout period. HAI rates obtained from the copper-containing new hospital wing (14,479 patient-days; 72 beds) and the unmodified hospital wing (19,177 patient-days) were compared with those from the baseline period (46,391 patient-days). The new wing had 78% (P = .023) fewer HAIs due to MDROs or C difficile, 83% (P = .048) fewer cases of C difficile infection, and 68% (P = .252) fewer infections due to MDROs relative to the baseline period. No changes in rates of HAI were observed in the unmodified hospital wing. CONCLUSIONS: Copper-impregnated composite hard surfaces and linens may be useful technologies to prevent HAIs in acute care hospital settings. Additional studies are needed to determine whether reduced HAIs can be attributed to the use of copper-containing antimicrobial hard and soft surfaces. PMID- 27692786 TI - Rates of catheter-associated urinary tract infection in tertiary care hospitals in 3 Arabian Gulf countries: A 6-year surveillance study. AB - BACKGROUND: The true burden of catheter-associated urinary tract infections (CAUTIs) remains largely unknown because of a lack of national and regional surveillance reports in Gulf Cooperation Council (GCC) countries. The purpose of this study was to estimate location-specific CAUTI rates in the GCC region and to compare them with published reports from the U.S. National Healthcare Safety Network (NHSN) and the International Nosocomial Infection Control Consortium (INICC). METHODS: CAUTI rates and urinary catheter utilization between 2008 and 2013 were calculated using NHSN methodology pooled from 6 hospitals in 3 GCC countries: Saudi Arabia, Oman, and Bahrain. The standardized infection ratios of the CAUTIs were compared with published reports of the NHSN and INICC. RESULTS: A total of 286 CAUTI events were diagnosed during 6 years of surveillance, covering 89,254 catheter days and 113,807 patient days. The overall CAUTI rate was 3.2 per 1,000 catheter days (95% confidence interval, 2.8-3.6), with an overall urinary catheter utilization of 0.78. The CAUTI rates showed a wide variability between participating hospitals, with approximately 80% reduction during the study. The overall compliance with the urinary catheter bundle implementation during the second half of the study was 65%. The risk of CAUTI in GCC hospitals was 35% higher than the NHSN hospitals, but 37% lower than the INICC hospitals. CONCLUSIONS: CAUTI rates pooled from a sample of GCC hospitals are quite different from rates in both developing and developed countries. PMID- 27692788 TI - Implementation of respiratory protection measures: Visitors of residential care homes for the elderly. AB - To evaluate the implementation of respiratory protection measures for and by visitors of residential care homes for the elderly in Hong Kong, a territory-wide cross-sectional survey was conducted. A total of 87 infection control officers, 1,763 health care workers, and 520 visitors from 87 homes completed the questionnaires. Rules on respiratory protection for visitors were found to vary across residential care homes for the elderly. Uncooperative visitors and inadequate resources were identified as major barriers in the implementation of such measures for visitors. PMID- 27692787 TI - Copper alloy surfaces sustain terminal cleaning levels in a rural hospital. AB - OBJECTIVE: To assess the ability of copper alloy surfaces to mitigate the bacterial burden associated with commonly touched surfaces in conjunction with daily and terminal cleaning in rural hospital settings. DESIGN: A prospective intention-to-treat trial design was used to evaluate the effectiveness of cooper alloy surfaces and respective controls to augment infection control practices under pragmatic conditions. SETTING: Half of the patient rooms in the medical surgical suite in a 49-bed rural hospital were outfitted with copper alloy materials. The control rooms maintained traditional plastic, metal, and porcelain surfaces. METHODS: The primary outcome was a comparison of the bacterial burden harbored by 20 surfaces and components associated with control and intervention areas for 12 months. Locations were swabbed regardless of the occupancy status of the patient room. Significance was assessed using nonparametric methods employing the Mann-Whitney U test with significance assessed at P < .05. RESULTS: Components fabricated using copper alloys were found to have significantly lower concentrations of bacteria, at or below levels prescribed, upon completion of terminal cleaning. Vacant rooms were found to harbor significant concentrations of bacteria, whereas those fabricated from copper alloys were found to be at or below those concentrations prescribed subsequent to terminal cleaning. CONCLUSIONS: Copper alloys can significantly decrease the burden harbored on high touch surfaces, and thus warrant inclusion in an integrated infection control strategy for rural hospitals. PMID- 27692789 TI - Constant load and constant volume response of municipal solid waste in simple shear. AB - Constant load and constant volume simple shear testing was conducted on relatively fresh municipal solid waste (MSW) from two landfills in the United States, one in Michigan and a second in Texas, at respective natural moisture content below field capacity. The results were assessed in terms of two failure strain criteria, at 10% and 30% shear strain, and two interpretations of effective friction angle. Overall, friction angle obtained assuming that the failure plane is horizontal and at 10% shear strain resulted in a conservative estimation of shear strength of MSW. Comparisons between constant volume and constant load simple shear testing results indicated significant differences in the shear response of MSW with the shear resistance in constant volume being lower than the shear resistance in constant load. The majority of specimens were nearly uncompacted during specimen preparation to reproduce the state of MSW in bioreactor landfills or in uncontrolled waste dumps. The specimens had identical percentage of <20mm material but the type of <20mm material was different. The <20mm fraction from Texas was finer and of high plasticity. MSW from Texas was overall weaker in both constant load and constant volume conditions compared to Michigan waste. The results of these tests suggest the possibility of significantly lower shear strength of MSW in bioreactor landfills where waste is placed with low compaction effort and constant volume, i.e., "undrained", conditions may occur. Compacted MSW specimens resulted in shear strength parameters that are higher than uncompacted specimens and closer to values reported in the literature. However, the normalized undrained shear strength in simple shear for uncompacted and compacted MSW was still higher than the normalized undrained shear strength reported in the literature for clayey and silty soils. PMID- 27692790 TI - Changes in the ecological properties of organic wastes during their biological treatment. AB - Organic wastes, such as the organic fractions of municipal solid waste (OFMSW) or sewage sludge (SS), have become a serious environmental problem in Russia as well as in other countries. The use of these wastes as soil amendments allows their negative impact on the environment to be minimized. However, before these wastes can be used, they need to be treated appropriately in order to decrease their level of hazard. In this study, composting of raw SS, OFMSW, a mixture of these two wastes (OFMSW+SS) at a ratio 1:2 as well as the anaerobically digested variants of these wastes (SSd, OFMSWd and OFMSWd+SSd) mixed with oiled sawdust was performed. Composting was conducted in the containers containing 20kg of the wastes. The results of three elutriate bioassays (with water flea Daphnia magna, infusoria Paramecium caudatum and radish plant, Raphanus sativus) and one contact bioassay (with oat plant Avena sativa) were used to indirectly estimate changes in the hazardous properties of the biological treatments. Besides, Corg, Ntot content and pH were analyzed in the process of composting. Within the study stability tests to determine maturation process completion were not carried out. It was revealed, that in the process of anaerobic pretreatment for 15days, the toxicity increased by a mean of 1.3-, 1.9- and 1.1-fold for OFMSW, SS and OFMSW+SS, respectively. During composting, the toxicity level of these pretreated samples decreased more rapidly as compared with those which were not pretreated. As a result, the toxicity levels of the elutriates from the final composts made of pretreated wastes OFMSW, SS and OFMSW+SS were three-, two- and 17-fold lower for D. magna and 15-, 21- and 12-fold lower for P. caudatum. As follows from phytotoxicity estimations, composts from digested substrates became mature on the 60th day and had a stimulation effect on the plants after the 90th day of incubation. For the composts prepared from raw substrates, a significantly longer period was needed for maturation. On the basis of ecotoxicity changes of the wastes treated, it can be concluded that anaerobic pretreatment of the municipal solid wastes is an effective acceleration tool for further composting and that waste mixtures can be treated more efficient as compared with raw wastes. PMID- 27692791 TI - Is there a relationship between impaired median nerve excursion and carpal tunnel syndrome? A systematic review. AB - STUDY DESIGN: Systematic review. INTRODUCTION: It is accepted that the etiology of carpal tunnel syndrome (CTS) is multifactorial. One of the most commonly accepted etiologic factors for CTS is compromise of the kinematic behavior and excursion of the median nerve. PURPOSE OF THE STUDY: The objective of this systematic review was to establish if there is a relationship between impaired median nerve excursion and CTS. METHODS: A systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, was conducted. Studies were sought where in vivo median nerve excursion was compared between people with CTS to an appropriate control group. Quality appraisal for each study was conducted using the Newcastle-Ottawa Scale by 2 independent evaluators. RESULTS: Ten case-control studies using ultrasound imaging to quantify median nerve excursion were included. All studies were rated as of "moderate" methodologic quality having scored 6 or 7 (of 9 stars) for the Newcastle-Ottawa Scale. Seven of the 10 studies concluded that median nerve excursion was reduced in a CTS population when compared with controls. CONCLUSION: The literature suggests that median nerve excursion is reduced in people with CTS when compared with healthy controls. LEVEL OF EVIDENCE: 3a.

PMID- 27692792 TI - Incidence, characteristics, and management of recently diagnosed, microscopically invasive breast cancer by receptor status: Iowa SEER 2000 to 2013. AB - BACKGROUND: Recent incidence, treatment patterns, and outcomes for node negative microscopically invasive breast cancer (MIBC) have not been reported. METHODS: State Health Registry of Iowa data identified women with ductal carcinoma in situ (DCIS), MIBC, and stage I breast cancer excluding MIBC (stage 1BC). RESULTS: From 2000 to 2013, 1,706, 193, and 4,514 women were diagnosed with DCIS, MIBC, and stage 1BC, respectively. MIBC increased at an annual percentage change of 2.1 (P = .041). MIBC was more frequently human epidermal growth factor receptor 2 positive than stage 1BC (39.7% vs 9.6%, P < .001). Mastectomy was performed more frequently in MIBC than DCIS (40.9% vs 30.6%, P = .014) or stage 1BC (40.9% vs 33.8%, P = .119). Chemotherapy was given to 4.1% of women with MIBC. Survival for women with MIBC was intermediate between DCIS and stage 1BC. CONCLUSIONS: Management of MIBC is an increasingly frequent clinical scenario. Women with MIBC receive more aggressive local and systemic therapy than women with DCIS. PMID- 27692794 TI - Outcomes and feasibility of nipple-sparing mastectomy for node-positive breast cancer Patients. AB - BACKGROUND: While nipple-sparing mastectomy (NSM) is gaining acceptance for risk reduction and for treatment of early stage breast cancer, node-positive disease remains a relative contraindication. Our aim was to evaluate the use and outcomes of NSM in node-positive breast cancer patients. METHODS: We identified 240 cancers in 226 patients (14 bilateral) scheduled for NSM and operated on between 1/2009 and 6/2014. We compared outcomes for 58 node-positive vs 182 node-negative patients. RESULTS: Intraoperative conversion to skin-sparing mastectomy was similar for node-positive and node-negative patients, 10% and 7%, as was 1-year success of NSM, 84% and 90%, respectively. Five-year locoregional disease-free estimates were 82% (95% CI 68%-99%) for node-positive and 99% (95% CI 96%-100%) for node-negative patients, P = .004; however, there were no nipple-areolar recurrences among node-positive patients. CONCLUSIONS: With careful consideration of biologic and anatomic risk factors for recurrence, these data suggest that NSM is a reasonable option for selected node-positive breast cancer patients. PMID- 27692795 TI - Ontogenetic shifts in the diet of plains hog-nosed snakes (Heterodon nasicus) revealed by stable isotope analysis. AB - Wild snake diets are difficult to study using traditional methods, but stable isotopes offer several advantages, including integrating dietary information over time, providing data from individuals that have not fed recently, and avoiding bias towards slowly-digesting prey items. We used stable isotope signatures of carbon and nitrogen from scale tissue, red blood cells, and blood plasma to assess the diet of wild plains hog-nosed snakes (Heterodon nasicus) in Illinois. We developed Bayesian mixing models which, taken together, predicted that H. nasicus shifted from a juvenile diet predominantly (31-63%) composed of six-lined racerunners (Aspidoscelis sexlineatus) and their eggs to an adult diet predominantly (44-56%) composed of eggs of the aquatic turtles Chrysemys picta and Chelydra serpentina, with a contribution from toads (Anaxyrus sp.; 6-27%) during their adolescent years. These results agreed with sparse data from gut contents. Combining traditional and isotopic techniques for studying the diets of wild snakes can increase the utility of both types of data. PMID- 27692796 TI - Pupillometry registers toddlers' sensitivity to degrees of mispronunciation. AB - This study introduces a method ideally suited for investigating toddlers' ability to detect mispronunciations in lexical representations: pupillometry. Previous research has established that the magnitude of pupil dilation reflects differing levels of cognitive effort. Building on those findings, we use pupil dilation to study the level of detail encoded in lexical representations with 30-month-old children whose lexicons allow for a featurally balanced stimulus set. In each trial, we present a picture followed by a corresponding auditory label. By systematically manipulating the number of feature changes in the onset of the label (e.g., baby~daby~faby~shaby), we tested whether featural distance predicts the degree of pupil dilation. Our findings support the existence of a relationship between featural distance and pupil dilation. First, mispronounced words are associated with a larger degree of dilation than correct forms. Second, words that deviate more from the correct form are related to a larger dilation than words that deviate less. This pattern indicates that toddlers are sensitive to the degree of mispronunciation, and as such it corroborates previous work that found word recognition modulated by sub-segmental detail and by the degree of mismatch. Thus, we establish that pupillometry provides a viable alternative to paradigms that require overt behavioral response in increasing our understanding of the development of lexical representations.

PMID- 27692798 TI - Biomechanical responses to changes in friction on a clay court surface. AB - OBJECTIVES: To examine the influence of clay court frictional properties on tennis players' biomechanical response. DESIGN: Repeated measures. METHODS: Lower limb kinematic and force data were collected on sixteen university tennis players during 10*180 degrees turns (running approach speed 3.9+/-0.20ms-1) on a synthetic clay surface of varying friction levels. To adjust friction levels the volume of sand infill above the force plate was altered (kg per m2 surface area; 12, 16 and 20kgm-2). Repeated measures ANOVA and Bonferroni's corrected alpha post-hoc analyses were conducted to identify significant differences in lower limb biomechanics between friction levels. RESULTS: Greater sliding distances (etap2=0.355, p=0.008) were observed for the lowest friction condition (20kgm-2) compared to the 12 and 16kgm-2 conditions. No differences in ankle joint kinematics and knee flexion angles were observed. Later peak knee flexion occurred on the 20kgm-2 condition compared to the 12kgm-2 (etap2=0.270, p=0.023). Lower vertical (etap2=0.345, p=0.027) and shear (etap2=0.396, p=0.016) loading rates occurred for the 20kgm2 condition compared to the 16kgm2. CONCLUSIONS: Lower loading rates and greater sliding distances when clay surface friction was reduced suggests load was more evenly distributed over time reducing players' injury risks. The greater sliding distances reported were accompanied with later occurrence of peak knee flexion, suggesting longer time spent braking and a greater requirement for muscular control increasing the likelihood of fatigue. PMID- 27692799 TI - Human fibroblasts treated with hydrogen peroxide stimulate human melanoblast proliferation and melanocyte differentiation, but inhibit melanocyte proliferation in serum-free co-culture system. AB - BACKGROUND: Oxidative stress caused by hydrogen peroxide (H2O2) elicits harmful effects on human melanocytes such as DNA damage and cell death. On the contrary, H2O2 is known to possess beneficial effects on melanocytes. However, mechanisms of the beneficial effects of H2O2 on melanocytes have not been fully understood, especially the indirect effects on melanocyte proliferation and differentiation from cells constituting surrounding tissue environment such as fibroblasts. OBJECTIVE: The aim of this study was to clarify whether H2O2-treated human fibroblasts affect the proliferation and differentiation of human melanocytes using serum-free co-culture system. METHODS: Epidermal melanoblasts and melanocytes were co-cultured with H2O2-treated or control fibroblasts in serum free culture media. The effects of H2O2-treated fibroblasts were detected by changes in the proliferation and differentiation of melanoblasts/melanocytes. RESULTS: H2O2-treated fibroblasts stimulated the proliferation of melanoblasts and the differentiation, melanogenesis, and dendritogenesis of melanocytes, but inhibited the proliferation of melanocytes. In the melanocytes co-cultured with H2O2-treated fibroblasts, the expression of tyrosinase (TYR), tyrosinase-related protein 1 (TYRP1), and KIT was increased, whereas TYRP2 and microphthalmia associated transcription factor showed no change. CONCLUSION: These results suggest that H2O2-treated fibroblasts can produce and release some mitogenic and melanogenic factors toward melanoblasts in addition to some proliferation inhibiting factors toward melanocytes. The stimulation of melanocyte differentiation seems to be performed through the upregulation of TYR, TYRP1, and KIT. PMID- 27692800 TI - Sex biology contributions to vulnerability to Alzheimer's disease: A think tank convened by the Women's Alzheimer's Research Initiative. AB - More than 5 million Americans are living with Alzheimer's disease (AD) today, and nearly two-thirds of Americans with AD are women. This sex difference may be due to the higher longevity women generally experience; however, increasing evidence suggests that longevity alone is not a sufficient explanation and there may be other factors at play. The Alzheimer's Association convened an expert think tank to focus on the state of the science and level of evidence around gender and biological sex differences for AD, including the knowledge gaps and areas of science that need to be more fully addressed. This article summarizes the think tank discussion, moving forward a research agenda and funding program to better understand the biological underpinnings of sex- and gender-related disparities of risk for AD. PMID- 27692801 TI - Risk of Prolonged Opioid Use Among Opioid-Naive Patients Following Common Hand Surgery Procedures. AB - PURPOSE: To evaluate prolonged opioid use in opioid-naive patients after common hand surgery procedures in the United States. METHODS: We studied insurance claims from the Truven MarketScan databases to identify opioid-naive adult patients (no opioid exposure 11 months before the perioperative period) who underwent an elective (carpal tunnel release, carpometacarpal arthroplasty/arthrodesis, cubital tunnel release, or trigger finger release) or trauma-related (closed distal radius fracture fixation, flexor tendon repair, metacarpal fracture fixation, or phalangeal fracture fixation) hand surgery procedure between 2010 and 2012 (N = 77,573 patients). Patients were observed for 6 months to determine the number, timing, duration, and oral morphine equivalent dosage of postoperative opioid prescriptions. We assessed prolonged postoperative opioid use, defined as patients who filled a perioperative opioid prescription followed by a prescription between 90 and 180 days after surgery, and evaluated associated risk factors using multivariable logistic regression. RESULTS: In this cohort, 59,725 opioid-naive patients (77%) filled a perioperative opioid prescription. Of these, 13% of patients continued to fill prescriptions between 90 and 180 days after surgery. Elective surgery patients were more likely to continue to fill opioid prescriptions after 90 days compared with trauma patients (13.5% vs 10.5%). Younger age, female gender, lower income, comprehensive insurance, higher Elixhauser comorbidity index, mental health disorders, and tobacco dependence or abuse were associated with prolonged opioid use. CONCLUSIONS: Approximately 13% of opioid-naive patients continue to fill opioid prescriptions after hand surgery procedures 90 days after surgery. Preoperative interventions centered on opioid alternatives and early cessation, particularly among patients at risk for long-term use, is critical to addressing the prescription opioid crisis in the United States. CLINICAL RELEVANCE: The current national opioid use epidemic requires an assessment of the prevalence of hand surgery patients who receive and fill opioid prescriptions after common hand surgery procedures. PMID- 27692802 TI - Molecular characteristics and antimicrobial resistance in invasive and noninvasive Group B Streptococcus between 2008 and 2015 in China. AB - Group B streptococcus (GBS) is an increasing pathogen threat to newborns and adults with immunodepressive diseases. Here, a total of 193 GBS, including 51 invasive and 142 noninvasive isolates, were collected from the patients with infections in 7 tertiary hospitals from 5 cities in China during the year 2008 to 2015. The strains of GBS were characterized by classical and molecular techniques for capsular polysaccharide serotyping, genes for pilus island (PI) and alpha like protein (alp), and antibiotic resistance profiling. Of 193 isolates, the predominant serotypes were III (45.6%) and Ia (18.7%). All strains carried at least 1 PI gene. The combination of PI-2b and PI-1 was present in 46.1% isolates, followed by PI-2a alone (80, 41.5%) and PI-2b alone (23, 11.9%). The most prevalent alp gene was rib (87, 45.1%), followed by alpha-C (47, 24.4%), epsilon (33, 17.1%), alp2/3 (7, 3.6%) and alp4 (2, 1.0%), respectively. The clonal relationships between strains were investigated using multilocus sequence typing. The strains were distinguished into 26 individual sequence typing, and further clustered into 6 clonal complexes. A significant association was noted between the distributions of alp genes, serotyping and PI profiles, such as serotype III rib-PI+PI-2a, Ib-alpha-C, and Ia-epsilon-PI-2a. No penicillin-resistant strains were detected, and 74.1%, 64.2%, and 68.9% were resistant to erythromycin, clindamycin, and tetracycline, respectively. The infective GBS isolates in China demonstrated epidemical features. PMID- 27692803 TI - Extraordinary Survival: What Does It Take? PMID- 27692804 TI - [Simple method for determining the size of the ProSeal laryngeal mask airway in children: a prospective observational study]. AB - BACKGROUND AND OBJECTIVES: The size of the ProSeal laryngeal mask airway in children is determined by the patient's weight. However, in some instances, an alternative method may be required. This study aimed to compare sizing by the auricle with conventional ProSeal laryngeal mask airway sizing by weight in children. METHODS: After approval by the institutional ethics board and written informed consent from parents, 197 children with American Society of Anesthesiologists physical status I-II who were scheduled for a routine genitourinary operation were included in the study. The correct ProSeal laryngeal mask airway size was determined according to the size of the auricle in children. The results were compared with the standard weight-based method recommended by the manufacturer's guidelines. The patients were classified into different groups depending on the ProSeal laryngeal mask airway sizes as determined by both methods. Agreement between both techniques was evaluated with kappa coefficient statistics. RESULTS: Insertion and adequate ventilation were achieved in 185 patients at the first attempt, and 12 patients required a second attempt. Three patients had to be intubated. Agreement between the two methods of size selection of the ProSeal laryngeal mask airway was moderate using kappa statistics. CONCLUSIONS: Choosing the size of the ProSeal laryngeal mask airway in children according to the auricle of the child is valid and practical. In particular, this is an alternative method in situations where the patient's weight is unknown, such as in emergency situations. PMID- 27692805 TI - [Design and validation of an oral health questionnaire for preoperative anaesthetic evaluation]. AB - BACKGROUND AND OBJECTIVES: Dental injuries incurred during endotracheal intubation are more frequent in patients with previous oral pathology. The study objectives were to develop an oral health questionnaire for preanaesthesia evaluation, easy to apply for personnel without special dental training; and establish a cut-off value for detecting persons with poor oral health. METHODS: Validation study of a self-administered questionnaire, designed according to a literature review and an expert group's recommendations. The questionnaire was applied to a sample of patients evaluated in a preanaesthesia consultation. Rasch analysis of the questionnaire psychometric properties included viability, acceptability, content validity and reliability of the scale. RESULTS: The sample included 115 individuals, 50.4% of men, with a median age of 58 years (range: 38 71). The final analysis of 11 items presented a Person Separation Index of 0.861 and good adjustment of data to the Rasch model. The scale was unidimensional and its items were not biased by sex, age or nationality. The oral health linear measure presented good construct validity. The cut-off value was set at 52 points. CONCLUSIONS: The questionnaire showed sufficient psychometric properties to be considered a reliable tool, valid for measuring the state of oral health in preoperative anaesthetic evaluations. PMID- 27692807 TI - Image-Rich Radiology Reports: A Value-Based Model to Improve Clinical Workflow. AB - PURPOSE: To determine the value of image-rich radiology reports (IRRR) by evaluating the interest and preferences of referring physicians, potential impact on clinical workflow, and the willingness of radiologists to create them. METHODS: Referring physicians and radiologists were interviewed in this prospective, HIPAA-compliant study. Subject willingness to participate in the study was determined by an e-mail. A single investigator conducted all interviews using a standard questionnaire. All subjects reviewed a video mockup demonstration of IRRR and three methods for viewing embedded images, as follows: (1) clickable hyperlinks to access a scrollable stack of images, (2) scrollable and enlargeable small-image thumbnails, and (3) scrollable but not enlargeable medium-sized images. Questionnaire responses, free comments, and general impressions were captured and analyzed. RESULTS: Seventy-two physicians (36 clinicians, 36 radiologists) were interviewed. Thirty-one clinicians (86%) expressed interest in using IRRR. Seventy-seven percent of subjects believed IRRR would improve communication. Ten clinicians (28%) preferred method 1, 18 (50%) preferred method 2, and 8 (22%) preferred method 3 for embedding images. Thirty clinicians (83%) stated that IRRR would improve efficiency. Twenty-two radiologists (61%) preferred selecting a tool button with a mouse and right clicking images to embed them, 13 (36%) preferred pressing a function key, and 11 (31%) preferred dictating series and image numbers. The average time radiologists were willing to expend for embedding images was 66.7 seconds. CONCLUSIONS: Referring physicians and radiologist both believe IRRR would add value by improving communication with the potential to improve the workflow efficiency of referring physicians. PMID- 27692808 TI - Surgery Clerkship Evaluations Are Insufficient for Clinical Skills Appraisal: The Value of a Medical Student Surgical Objective Structured Clinical Examination. AB - OBJECTIVE: Optimal methods for medical student assessment in surgery remain elusive. Faculty- and housestaff-written evaluations constitute the chief means of student assessment in medical education. However, numerous studies show that this approach has poor specificity and a high degree of subjectivity. We hypothesized that an objective structured clinical examination (OSCE) in the surgery clerkship would provide additional data on student performance that would confirm or augment other measures of assessment. DESIGN: We retrospectively reviewed data from OSCEs, National Board of Medical Examiners shelf examinations, oral presentations, and written evaluations for 51 third-year Harvard Medical School students rotating in surgery at Massachusetts General Hospital from 2014 to 2015. We expressed correlations between numeric variables in Pearson coefficients, stratified differences between rater groups by one-way analysis of variance, and compared percentages with 2-sample t-tests. We examined commentary from both OSCE and clinical written evaluations through textual analysis and summarized these results in percentages. RESULTS: OSCE scores and clinical evaluation scores correlated poorly with each other, as well as with shelf examination scores and oral presentation grades. Textual analysis of clinical evaluation comments revealed a heavy emphasis on motivational factors and praise, whereas OSCE written comments focused on cognitive processes, patient management, and methods to improve performance. CONCLUSIONS: In this single-center study, an OSCE provided clinical skills data that were not captured elsewhere in the surgery clerkship. Textual analysis of faculty evaluations reflected an emphasis on interpersonal skills, rather than appraisal of clinical acumen. These findings suggest complementary roles of faculty evaluations and OSCEs in medical student assessment. PMID- 27692806 TI - Human vascular progenitor cells derived from renal arteries are endothelial-like and assist in the repair of injured renal capillary networks. AB - Vascular progenitor cells show promise for the treatment of microvasculature endothelial injury. We investigated the function of renal artery progenitor cells derived from radical nephrectomy patients, in animal models of acute ischemic and hyperperfusion injuries. Present in human adventitia, CD34positive/CD105negative cells were clonal and expressed transcription factors Sox2/Oct4 as well as surface markers CXCR4 (CD184)/KDR(CD309) consistent with endothelial progenitor cells. Termed renal artery-derived vascular progenitor cells (RAPC), injected cells were associated with decreased serum creatinine after ischemia/reperfusion, reduced albuminuria after hyperperfusion, and improved blood flow in both models. A small population of RAPC integrated with the renal microvasculature following either experimental injury. At a cellular level, RAPC promoted local endothelial migration in co-culture. Profiling of RAPC microRNA identified high levels of miRNA 218; also found at high levels in exosomes isolated from RAPC conditioned media after cell contact for 24 hours. After hydrogen peroxide-induced endothelial injury, RAPC exosomes harbored Robo-1 transcript; a gene known to be regulated by mir218. Such exosomes enhanced endothelial cell migration in culture in the absence of RAPC. Thus, our work shows the feasibility of pre-emptive pro angiogenic progenitor cell procurement from a targeted patient population and potential therapeutic use in the form of autologous cell transplantation. PMID- 27692809 TI - Awareness of Surgeons in Saudi Arabia About the Surgical Costs and Investigations: Multicenter Study. AB - OBJECTIVE: To investigate the level of knowledge and awareness of the cost of the currently used blood investigations, imaging studies, admission cost, and surgical instrument among surgeons in Saudi Arabia. DESIGN: It was a cross section study conducted in Riyadh city, the capital of Saudi Arabia. SETTING: Multihealth centers including main University hospital, Military hospitals, and Ministry of health hospitals. All surgeons in the health facilities were invited to participate in the study. A questionnaire has been formulated, and distributed to all participants. It was composed of 3 sections such as: demographic data, awareness about the cost, and physicians' perception about the cost and the attitude of their institution toward cost practice. RESULT: Totally, 296 participants were enrolled in the study. More than half of the respondents were females (53.3%). Nearly two-thirds were in the young age group (30-40 years), 41.2% were residents. Only 4.4%, 3.4%, 8.4%, and 3.7% of the surgeons were fully aware of the cost of blood investigations, imaging studies, surgical instruments/prosthesis, and the medication that they prescribe, respectively. Most of them mentioned that their institute neither encourages them to consider a cost-effective practice (86.9%) nor monitor how cost effective is their practice (86.2%). CONCLUSION: Surgeon's knowledge and awareness about the cost of different medical procedures were insufficient. Surgeons' knowledge and attitudes about costs of care can be improved through the use of audit and feedback with patient cost and charge data, which could be attained through the inclusion of audit and feedback as part of a curriculum teaching. PMID- 27692810 TI - Effect of Bleomycin Administration on the Development of Pulmonary Toxicity in Patients With Metastatic Germ Cell Tumors Receiving First-Line Chemotherapy: A Meta-Analysis of Randomized Studies. AB - BACKGROUND: Limited information is available about the effect of bleomycin administration on the development of pulmonary toxicity in metastatic germ cell tumors (GCT). PATIENTS AND METHODS: A literature search was conducted to identify randomized trials of first-line chemotherapy for GCT. We conducted univariate and multivariate analyses using random effects models to evaluate the predictive role of bleomycin administration in the development of all Grade and Grade 3 to 4 (G3 4) pulmonary toxicity. The results were adjusted for length of follow-up, prognostic risk group, year of treatment, presence of lung metastases, and primary mediastinal GCT. RESULTS: Fifty-three study arms of 25 phase II and III trials encompassing 6498 patients were selected: 40 that used bleomycin (n = 5093) and 13 that did not (n = 1405). The pooled probability of all-Grade pulmonary toxicity in the bleomycin and nonbleomycin arms was 11.7% (95% confidence interval [CI], 8.4%-16.0%) and 1.7% (95% CI, 0.7%-4.2%), respectively. Univariate analysis indicated that bleomycin administration was associated with the incidence of all-Grade (odds ratio [OR], 7.57; 95% CI, 2.84-20.18; Wald test P < .001) and G3-4 pulmonary toxicity (OR, 5.19; 95% CI, 1.57-17.16; P = .007). Multivariate analysis showed a significant association of bleomycin administration with the incidence of all-Grade pulmonary toxicity (OR, 4.14; 95% CI, 1.36-12.59; P = .012) and a trend toward significance for G3-4 toxicity (OR, 2.24; 95% CI, 0.91-5.51; P = .080). CONCLUSION: We quantified the bleomycin associated effect on the development of pulmonary toxicity in patients with GCT who received first-line chemotherapy. This information might be useful for planning clinical trials aimed at reducing chemotherapy as well as to inform patients in the clinic. PMID- 27692811 TI - Clinical Impact of the Number of Treatment Cycles in First-Line Docetaxel for Patients With Metastatic Castration-Resistant Prostate Cancer. AB - BACKGROUND: We investigated the impact of the number of docetaxel cycles administered in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with first-line chemotherapy. PATIENTS AND METHODS: Charts from 421 consecutive patients who initiated standard treatment with docetaxel-based chemotherapy (75 mg/m2 every 3 weeks) between 2007 and 2013 were reviewed. Patients who received < 6 cycles of docetaxel were excluded from the analysis. Remaining patients were divided into 2 groups on the basis of whether or not >= 9 cycles of docetaxel were administered (n = 108 and 184, respectively). Reasons for treatment discontinuation and postdocetaxel treatments were registered. Prostate-specific antigen (PSA) responses were defined as a confirmed >= 50% decrease in baseline PSA levels. Overall survival (OS) was calculated from start of therapy using the Kaplan-Meier method. Cox proportional hazards were calculated to estimate the effect of clinical variables on OS. RESULTS: OS was longer in patients treated with >= 9 cycles of docetaxel (21.9 months vs. 17.2 months; P < .0001, log rank). Survival also favored patients treated with >= 9 cycles of docetaxel when only patients ending docetaxel because of toxicity or treatment conclusion (22.3 vs. 19.4 months; P = .048, log rank) or patients who achieved a PSA response (22.3 vs. 18.7 months; P = .012, log rank) were evaluated. mCRPC-related prognostic factors and patients who received >= 1 subsequent line of therapy post-docetaxel were well balanced. CONCLUSION: On the basis of our retrospective findings, a superior OS was found in patients treated with >= 9 cycles of docetaxel when adjusting for known prognostic factors. Dose reductions might increase the number of docetaxel cycles administered.

PMID- 27692814 TI - Concomitant and discrete expressions of aldose reductase and sorbitol dehydrogenase in the male reproductive tract. AB - This study aimed at investigating the expression and localization of the polyol pathway enzymes; aldose reductase (AR) and sorbitol dehydrogenase (SDH), in the male reproductive tract of rat. Gene expression analysis showed maximum expression of AR and SDH in the coagulating glands. Western blot analysis showed a coordinated presence of the two enzymes in the coagulating glands, seminal vesicle and epididymis. Immunohistochemistry showed a concordant expression of the two enzymes in the coagulating gland, which goes well with its function of fructose production in rats. A less concordant expression of the two enzymes in the seminal vesicle was also seen. Discrete expression of AR was seen in the Sertoli cells without SDH. Germ cells including sperm in the seminiferous tubules lacked AR, but SDH was present in all stages of developing germ cells including sperm present in the seminiferous tubules. The epithelial layer of epididymis showed the presence of AR, but it was negligible in vas deferens and prostate. SDH was not seen in the epithelial layer of epididymis, vas deferens or prostate. Though sperm in the seminiferous tubules lacked AR, sperm extracted from cauda showed the presence of both AR and SDH. Immunofluorescence localization of AR and SDH on sperm showed the presence of both the enzymes all over sperm. Discrete expression of AR in the Sertoli cells may be linked to detoxification of a number of metabolism by-products. Similarly, the presence of polyol enzymes on sperm in epididymis and beyond may be to tackle toxic metabolites they may encounter during their journey along the male or female reproductive tract. PMID- 27692812 TI - Predicting Time From Metastasis to Overall Survival in Castration-Resistant Prostate Cancer: Results From SEARCH. AB - OBJECTIVE: To identify the predictors of time from initial diagnosis of metastatic castration-resistance prostate cancer (mCRPC) to all-cause death within the Shared Equal Access Regional Cancer Hospital cohort. PATIENTS AND METHODS: We performed a retrospective analysis of 205 mCRPC men. Overall survival was estimated and plotted using the Kaplan-Meier method. The uni- and multivariable overall survival predictors were evaluated with the Cox proportional hazards model. A nomogram was generated to predict overall survival at 1, 2, 3, and 5 years after mCRPC. Concordance index and calibration plot were obtained. RESULTS: A total of 170 men (83%) died over a median follow-up of 41 months. In univariable analysis, older age, more remote year of mCRPC, nonblack race, greater number of bone metastasis, higher prostate-specific antigen (PSA) levels, shorter PSA doubling time, and faster PSA velocity at mCRPC diagnosis were significantly associated with shorter overall survival (all P < .05). In multivariable analysis, older age, more remote year of mCRPC, greater number of bone metastasis, higher PSA levels, and shorter PSA doubling time at mCRPC diagnosis remained significantly associated with shorter overall survival (all P < .05). On the basis of these variables, a nomogram was generated yielding a concordance index of 0.67 and good calibration. CONCLUSION: The use of clinical parameter such as age, disease burden, and PSA levels and kinetics can be used to estimate overall survival in mCRPC patients. PMID- 27692816 TI - From bench to pet shop to bedside? The environment and immune function in mice. AB - The generation of inbred mouse strains in the late 19th and early 20th centuries, coupled with the later establishment of specific pathogen-free animal research facilities created a powerful biological platform for exploration of the immune system in health and disease. Studies in this setting have been responsible for huge advances in our understanding of immunobiology and disease, including immune mediated kidney disease. However, whereas this reductionist and relatively standardized approach allows us to make sense of complex disease biology, it takes place in controlled environments that clearly differ from those that we humans encounter in everyday life. Recent studies comparing the immune systems of wild mice, pet shop mice, and laboratory mice suggest ways in which the murine immune system can be influenced to behave more like the human immune system.

AB - High blood pressure is a common cause of chronic kidney disease. Because CD40, a member of the tumor necrosis factor receptor family, has been linked to the progression of kidney disease in ischemic nephropathy, we studied the role of Cd40 in the development of hypertensive renal disease. The Cd40 gene was mutated in the Dahl S genetically hypertensive rat with renal disease by targeted-gene disruption using zinc-finger nuclease technology. These rats were then given low (0.3%) and high (2%) salt diets and compared. The resultant Cd40 mutants had significantly reduced levels of both urinary protein excretion (41.8 +/- 3.1 mg/24 h vs. 103.7 +/- 4.3 mg/24 h) and plasma creatinine (0.36 +/- 0.05 mg/dl vs. 1.15 +/- 0.19 mg/dl), with significantly higher creatinine clearance compared with the control S rats (3.04 +/- 0.48 ml/min vs. 0.93 +/- 0.15 ml/min), indicating renoprotection was conferred by mutation of the Cd40 locus. Furthermore, the Cd40 mutants had a significant attenuation in renal fibrosis, which persisted on the high salt diet. However, there was no difference in systolic blood pressure between the control and Cd40 mutant rats. Thus, these data serve as the first evidence for a direct link between Cd40 and hypertensive nephropathy. Hence, renal fibrosis is one of the underlying mechanisms by which Cd40 plays a crucial role in the development of hypertensive renal disease.

AB - The high-throughput, high-resolution phenotyping enabled by metabolomics has been applied increasingly to a variety of questions in nephrology research. This article provides an overview of current metabolomics methodologies and nomenclature, citing specific considerations in sample preparation, metabolite measurement, and data analysis that investigators should understand when examining the literature or designing a study. Furthermore, we review several notable findings that have emerged in the literature that both highlight some of the limitations of current profiling approaches, as well as outline specific strengths unique to metabolomics. More specifically, we review data on the following: (i) tryptophan metabolites and chronic kidney disease onset, illustrating the interpretation of metabolite data in the context of established biochemical pathways; (ii) trimethylamine-N-oxide and cardiovascular disease in chronic kidney disease, illustrating the integration of exogenous and endogenous inputs to the blood metabolome; and (iii) renal mitochondrial function in diabetic kidney disease and acute kidney injury, illustrating the potential for rapid translation of metabolite data for diagnostic or therapeutic aims. Finally, we review future directions, including the need to better characterize interperson and intraperson variation in the metabolome, pool existing data sets to identify the most robust signals, and capitalize on the discovery potential of emerging nontargeted methods.

PMID- 27692820 TI - Chronic Kidney Disease in the Second-Generation Drug-Eluting Stent Era: Pooled Analysis of the Korean Multicenter Drug-Eluting Stent Registry. AB - OBJECTIVES: The purpose of this study was to evaluate the clinical impact of chronic kidney disease (CKD) on clinical outcomes in contemporary practice of percutaneous coronary intervention (PCI) using second-generation drug-eluting stents (DES). BACKGROUND: Although second-generation DES have improved the safety and efficacy issues in PCI, data regarding the performance of second-generation DES in patients with CKD are still limited. METHODS: We performed a patient-level pooled analysis on 12,426 patients undergoing PCI using second-generation DES from the Korean Multicenter Drug-Eluting Stent Registry. Endpoints were stent oriented outcomes (target lesion failure [TLF]) and patient-oriented composite outcomes (POCO) during a median follow-up of 35 months. CKD patients were stratified by the estimated glomerular filtration rate (eGFR) from mild CKD to end-stage renal disease patients, and by the coexistence of diabetes mellitus (DM). RESULTS: A total of 2,927 patients had CKD (23.6%), who showed a significantly higher risk of TLF (adjusted hazard ratio [HRadjust]: 1.50; 95% confidence interval [CI]: 1.21 to 1.86) and POCO (HRadjust 1.34; 95% CI: 1.17 to 1.55) compared to patients with preserved renal function. Stratified analysis by eGFR showed that TLF was not increased in the mild to moderate CKD, whereas severe CKD and dialysis-dependent patients showed significantly higher risk of TLF (HRadjust 2.44; 95% CI: 1.54 to 3.86; HRadjust 3.58; 95% CI: 2.52 to 5.08, respectively). The eGFR threshold of increased clinical events was 40 to 45 ml/min/1.73 m2. Among CKD patients, DM CKD patients showed a higher incidence of TLF compared to non-DM CKD patients (HRadjust: 1.82; 95% CI: 1.32 to 2.52), driven by the increase in target vessel-related events. CONCLUSIONS: In the era of second-generation DES, CKD patients were at a significantly higher risk of clinical outcomes only in severe CKD and end-stage renal disease patients.

PMID- 27692824 TI - [Assessment of screening for Down syndrome in Martinique from 2011 to 2013: An island location favoured]. AB - OBJECTIVES: The aim of this study is to evaluate the screening for trisomy 21 (T21) between 2011 and 2013 on Martinique French West Indies after the decree of 23 June 2009. MATERIALS AND METHODS: Were used the prenatal data provided by accredited laboratories and the data from the Registry of Congenital French West Indies (REMALAN). RESULTS: A total of 85.9 % of patients underwent screening: 60.5 % on a combined calculation of risk (CRC), 14.6 % on a sequential calculation of risk (CRS) and 10.8 % on serum markers 2nd trimester (MST2). Overall 5.4 % of the patients were placed in a risk group. During this period, 47 trisomy 21 were identified by the REMALAN which 38 (80.1 %) were detected prenatally: 24 of CRC, 3 on MST2 and 11 on signs of ultrasound at the 1st and 2nd trimester. The sensitivity of the CRC was 88 % for a false positive rate of 3.87 %. The overall sensitivity of screening (CRC, CRS and MST2) was 87 % for a false positive rate of 5.21 %. CONCLUSION: These data show that the coverage rate in Martinique is satisfactory and the screening fir Down syndrome meet expectations. PMID- 27692825 TI - Establishing Age-Specific Cost-Effective Annual Revision Rates for Unicompartmental Knee Arthroplasty: A Meta-Analysis. AB - BACKGROUND: Improved survivorship has contributed to the increased use of unicompartmental knee arthroplasty (UKA) as an alternative to total knee arthroplasty (TKA) for unicompartmental knee osteoarthritis. However, heterogeneity among cost-effectiveness analysis studies comparing UKA to TKA has prevented the derivation of discrete implant survivorship targets. The aim of this meta-analysis was to determine the age-stratified annual revision rate (ARR) threshold for UKA to become consistently cost-effective for unicompartmental knee osteoarthritis. METHODS: A systematic search was performed for cost-effectiveness analysis studies of UKA vs TKA. Selected publications were rated by evidence level and assessed for methodological quality. Target UKA survivorship values determined by sensitivity analysis were retrieved, converted to ARR, and combined by age category (<65, 65-74, and >=75 years) to estimate age-specific cost effectiveness thresholds. RESULTS: Four studies met all inclusion criteria. All publications were evidence level I-B, with high methodological quality. Combined data indicated median threshold cost-effective ARR of 1.471% (interquartile range [IQR], 1.415-1.833; age <65), 1.135% (IQR, 1.011-1.260; age 65-74), and 1.760% (IQR, 1.660-2.880; age >=75). Current revision rates are already below the cost effective threshold for patients aged >=75, but exceed recommended values in younger patients. CONCLUSION: The findings indicate that implant survivorship is a limiting factor toward achieving cost-effective UKA in patients aged <65. Strategies to improve UKA survivorship, such as shifting procedures to high volume centers, may render UKA cost-effective in younger patients. This presents an opportunity for resource reallocation within health systems to achieve cost effective utilization of UKA across a broader population segment.

PMID- 27692828 TI - Happy@feet application for the management of diabetic foot osteomyelitis. AB - OBJECTIVE: We aimed to develop and implement an application that could improve the management of patients presenting with diabetic foot osteomyelitis. PATIENTS AND METHODS: Physicians from the multidisciplinary diabetic foot infection team and a software engineer first assessed the needs required for the infection management and application. An experimental version was then designed and progressively improved. A final version was implemented in clinical practice in 2013 by the multidisciplinary diabetic foot infection team of our university hospital. RESULTS: The application, known as Happy@feet, helps gather and allows access to all required data for patient management, dispenses prescriptions (antibiotics, nursing care, blood tests), and helps follow the evolution of the wound. At the end of the consultation, a customizable letter is generated and may be directly sent to the persons concerned. This application also facilitates clinical and economic research. In 2014, Happy@feet was used to follow 83 patients during 271 consultations, 88 of which were day care hospitalizations. CONCLUSION: The Happy@feet application is useful to manage these complex patients. Once the learning period is over, the time required for data collection is compensated by the rapid dispense of prescriptions and letters. Happy@feet can be used for research projects and will be used in a remote patient management project. PMID- 27692829 TI - Invasive toxocariasis with hepatic lesions.

PMID- 27692831 TI - 7-Chloro-4-aminoquinoline gamma-hydroxy-gamma-lactam derived-tetramates as a new family of antimalarial compounds. AB - In this Letter we report on an efficient and short 2-3 steps synthesis of gamma hydroxy-gamma-lactam derived-tetramates bearing a 7-chloro-4-aminoquinoline skeleton and their evaluation as potent antimalarials. These molecules were obtained through ring opening-ring closure (RORC) process of gamma-ylidene tetronate derivatives in the presence of 7-chloro-4-aminoquinoline-derived amines. In vitro antimalarial activity of these new gamma-lactams was evaluated against Plasmodium falciparum clones of variable sensitivity (3D7 and W2) and they were found to be active in the range of 14-827nM with generally good resistance index. A preliminary SAR study is also presented to explain these results. Finally, the most active compounds did not show in vitro cytotoxicity when tested against Human Umbilical Vein Endothelial Cells (HUVEC) up to concentration of 50MUM and they were stable at pH 7.4 for at least 48h.

PMID- 27692833 TI - Risk of lymph node metastases in pathological gleason score<=6 prostate adenocarcinoma: Analysis of institutional and population-based databases. AB - INTRODUCTION: Several institutional studies have suggested that pathological Gleason score<=6 prostate cancer has little or no capacity for metastasis. MATERIALS AND METHODS: Using the Surveillance, Epidemiology, and End Results database (SEER, 2004-2011, n = 19,594) and the National Cancer Database (NCDB, 2004-2013, n = 57,540), we identified patients with pathological Gleason score<=6 prostate cancer following radical prostatectomy and lymph node dissection. At the University of Chicago Medicine (UCM, 2003-2014), we considered men with Gleason score<=6 prostate cancer who did (n = 267) and did not receive (n = 770) a lymph node dissection at the time of radical prostatectomy. Temporal trends in lymph node dissection and lymph node metastases were determined, and multivariable logistic regressions were used to analyze factors associated with lymph node metastases. In the UCM cohort, we also evaluated secondary endpoints, including biochemical recurrence (BCR), metastatic disease on follow-up imaging, and response to salvage radiation therapy. RESULTS: The incidence of lymph node dissection at the time of radical prostatectomy decreased from 60% to 37% in SEER (2004-2011) and from 62% to 45% in NCDB (2004-2013). Positive lymph node metastases were found in 0.2% of SEER and 0.18% of NCDB patients who received a lymph node dissection. Elevated PSA, higher clinical stage, and African American race were associated with lymph node positivity in one or both of these databases (P<0.05). Among UCM patients who received a lymph node dissection, no lymph node metastases were found, though a BCR occurred in 3 cases (1%). All 3 men responded favorably to salvage therapy, suggestive of local recurrence. A total of 21 patients (3%) from UCM who did not receive a lymph node dissection had a BCR and underwent salvage radiation therapy. Of these, 4 patients had persistently detectable PSA levels without evidence of local or distant disease at median follow-up of 65 months (range: 29-79) following salvage therapy. Surgical specimens were available for contemporary pathologic review in 3 of these cases, and all were upgraded to Gleason 7 disease. CONCLUSIONS: Our population-based and institutional analyses suggest metastases in cases of Gleason score<=6 prostate cancer to be extremely rare. PMID- 27692834 TI - Localized chromophobe carcinomas treated by nephron-sparing surgery have excellent oncologic outcomes. AB - OBJECTIVE: To evaluate the oncologic outcomes of nephron-sparing surgery (NSS) for localized chromophobe renal cell carcinoma (cRCC). MATERIAL AND METHODS: We performed a multicenter international study involving the French Network for Research on Kidney Cancer (UroCCR) and 5 international teams. Data from 808 patients treated with NSS between 2004 and 2014 for non-clear cell RCCs were analyzed. RESULTS: We included 234 patients with cRCC. There were 123 (52.6%) females. Median age was 61 (23-88) years. Median tumor size was 3 (1-11)cm. A positive surgical margin was identified in 14 specimens (6%). Pathologic stages were T1, T2, and T3a in 202 (86.3%), 9 (3.8%), and 23 (9.8%) cases, respectively. After a mean follow-up of 46.6 +/- 36 months, 2 (0.8%) patients experienced a local recurrence. No patient had metastatic progression, and no patient died from cancer. Three-years estimated cancer-free survival and cancer-specific survival were 99.1% and 100%, respectively. CONCLUSION: Oncological results of NSS for localized cRCC are excellent. In this series, only 2 patients had a local recurrence, and no patient had metastatic progression or died from cancer. PMID- 27692836 TI - Predictive models and risk of biopsy progression in active surveillance patients. AB - OBJECTIVE: To analyze the performance of different radical prostatectomy-based prognostic tools in predicting the biopsy progression in our active surveillance cohort. MATERIALS AND METHODS: We analyzed 326 patients with biopsy Gleason grade<=6,<=2 positive biopsy cores,<=20% tumor present in any core, prostate specific antigen<15ng/dl, and clinical stages T1-T2a all of whom had at least single surveillance biopsy. Probabilities of pathologically relatively aggressive disease were estimated using Partin and Dinh risk tables and Kattan, Truong, and Kulkarni nomograms for each individual patient. Using these predictions, performance of these tools was quantified regarding discrimination, stratification at different cut-points, calibration, and the clinical net benefit. RESULTS: Predictions of Partin and Dinh tables were not associated with the biopsy progression. The predictive value of Kattan and Truong nomograms was higher when compared with the other tools, although it was significant only on the first and second surveillance biopsies. Both nomograms were able to identify low- and high-risk subgroups within the cohort. Kattan nomogram demonstrated better correlation with the observed rate of progression over the first 3 biopsies and higher clinical net benefit. CONCLUSION: Kattan and Truong nomograms demonstrated the best performance in predicting biopsy progression, although their value was largely limited to the first 2 surveillance biopsies. Both tools were able to stratify patients into subgroups with different risks of progression. These nomograms have important differences, which suggest that a more effective predictive model combining the strong sides of both tools and possibly some other variables could be developed. PMID- 27692837 TI - Central zone lesions on magnetic resonance imaging: Should we be concerned? AB - INTRODUCTION AND OBJECTIVE: The Prostate Imaging Reporting and Data System (PI RADS) score was developed to evaluate lesions in the peripheral and transition zone on multiparametric magnetic resonance imaging (mpMRI) of the prostate. We aim to determine if the PI-RADS scoring system can be used to evaluate central zone lesions on mpMRI. MATERIALS AND METHODS: A retrospective review of 73 patients who underwent mpMRI/ultrasound (US) fusion-guided biopsy of 143 suspicious lesions between February 2014 and October 2015 was performed. All patients underwent a 3T mpMRI. Indications for mpMRI included an abnormal digital rectal examination, PSA velocity >0.75ng/dl/y, and patients on active surveillance. The mpMRI sequence involved T2-weighted imaging, diffusion-weighted imaging, and dynamic contrast enhancement. Using 3-dimensional model software (Invivo Corporation, Gainesville, FL, USA), a minimum of 3 magnetic resonance imaging (MRI)/US fusion-guided biopsy samples were taken from each prostate lesion seen on mpMRI irrespective of PI-RADS score, using local anesthesia in an outpatient clinic setting. RESULTS: A total of 73 patients underwent MRI/US fusion-guided biopsy of 85 peripheral zone lesions, 31 transitional zone lesions, and 27 central zone lesions. Only 2 (7%) of central zone lesions were positive for prostate cancer. Both patients had lesions which were graded as PI-RADS 3. Both the patients had multifocal lesions that encompassed>=50% of the central and transition zones on the sagittal view MRI images. Both patients previously had transrectal US-guided biopsy of the prostate which was negative for cancer. Both patients underwent a robotic-assisted laparoscopic prostatectomy, each revealing high-grade cancer. CONCLUSIONS: Lesions involving only the central gland/zone seen on MRI are less concerning for malignancy and should not be given equal weight as peripheral zone lesions. In this series, no lesions involving solely the central gland/zone, regardless of PI-RADS score, was positive for malignancy on MRI/US fusion-guided biopsy. Consideration of a modified PI-RADS scoring system should be given to help identify central zone lesions with malignant potential. PMID- 27692835 TI - Hepatoma-derived growth factor: A survival-related protein in prostate oncogenesis and a potential target for vitamin K2. AB - Hepatoma-derived growth factor (HDGF) is a heparin-binding growth factor, which has previously been shown to be expressed in a variety of cancers. HDGF overexpression has also previously been correlated with a poor prognosis in several cancers. The significance of HDGF in prostate cancer, however, has not been investigated. Here, we show that HDGF is overexpressed in both androgen sensitive LNCaP cells and androgen-insensitive DU145, 22RV1, and PC-3 cells. Forced overexpression enhanced cell viability of RWPE-1 cells, whereas HDGF knockdown reduced cell proliferation in human prostate cancer cells. We also show that HDGF may serve as a survival-related protein as ectopic overexpression of HDGF in RWPE cells up-regulated the expression of antiapoptosis proteins cyclin E and BCL-2, whereas simultaneously down-regulating proapoptotic protein BAX. Western blot analysis also showed that HDGF overexpression modulated the activity of phospho-AKT as well as NF-kB, and these results correlated with in vitro migration and invasion assays. We next assessed the therapeutic potential of HDGF inhibition with a HDGF monoclonal antibody and vitamin k2, showing reduced cell proliferation as well as inhibition of NF-kB expression in HDGF overexpressed RWPE cells treated with a HDGF monoclonal antibody and vitamin K2. Collectively, our results suggest that HDGF is a relevant protein in prostate oncogenesis and may serve as a potential therapeutic target in prostate cancer. PMID- 27692838 TI - Pulmonary Contusion and Traumatic Pneumatoceles in a Platform Diver with Hemoptysis. AB - BACKGROUND: Injuries in divers resulting purely from impact with the water are uncommon in the published literature. We present a case report of pulmonary contusion in a young diver. CASE REPORT: A young, healthy competitive platform diver landed flat on his back in the water from a dive of 10 meters. He complained of upper back pain and had an episode of hemoptysis after the dive. He was initially observed for 15 hours postinjury, and was discharged when three chest radiographs (CXRs) taken at 1, 7, and 11 hours postinjury did not show significant abnormalities. Thirty-six hours postinjury, the patient experienced repeat hemoptysis and returned to the emergency department, where a fourth CXR performed 43 hours postinjury was normal. A computed tomography (CT) scan revealed pulmonary contusion and traumatic subpleural pneumatoceles. The patient was admitted to the cardiothoracic ward for observation. He recovered well with conservative treatment and was discharged on the fifth day after injury with clearance for air travel. In this patient with a high-energy mechanism of rapid deceleration and hemoptysis at the scene, there may be grounds for performing a CT scan of the thorax at the time of the first presentation, although the CT findings did not change conservative management of this patient. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should recognize that a dive into water may generate sufficient impact to produce a pulmonary contusion. If the patient is clinically well and the CXR results are normal, the decision to initiate a CT scan and subsequent disposition may be based on clinical judgement and institutional practice. PMID- 27692839 TI - Survey and Chart Review to Estimate Medicare Cost Savings for Home Health as an Alternative to Hospital Admission Following Emergency Department Treatment. AB - BACKGROUND: Almost 70% of hospital admissions for Medicare beneficiaries originate in the emergency department (ED). Research suggests that some of these patients' needs may be better met through home-based care options after evaluation and treatment in the ED. OBJECTIVE: We sought to estimate Medicare cost savings resulting from using the Home Health benefit to provide treatment, when appropriate, as an alternative to inpatient admission from the ED. METHODS: This is a prospective study of patients admitted from the ED. A survey tool was used to query both emergency physicians (EPs) and patient medical record data to identify potential candidates and treatments for home-based care alternatives. Patient preferences were also surveyed. Cost savings were estimated by developing a model of Medicare Home Health to serve as a counterpart to the actual hospital based care. RESULTS: EPs identified 40% of the admitted patients included in the study as candidates for home-based care. The top three major diagnostic categories included diseases and disorders of the respiratory system, digestive system, and skin. Services included intravenous hydration, intravenous antibiotics, and laboratory testing. The average estimated cost savings between the Medicare inpatient reimbursement and the Home Health counterpart was approximately $4000. Of the candidate patients surveyed, 79% indicated a preference for home-based care after treatment in the ED. CONCLUSIONS: Some Medicare beneficiaries could be referred to Home Health from the ED with a concomitant reduction in Medicare expenditures. Additional studies are needed to compare outcomes, develop the logistical pathways, and analyze infrastructure costs and incentives to enable Medicare Home Health options from the ED. PMID- 27692840 TI - Clinical Mimics: An Emergency Medicine-Focused Review of Sepsis Mimics. AB - BACKGROUND: Sepsis is a common clinical condition, and mortality and morbidity may be severe. The current definition of sepsis involves systemic inflammatory response syndrome (SIRS) criteria, which is met by many conditions. OBJECTIVE: This review evaluates the SIRS continuum, signs and symptoms of sepsis, mimics of sepsis, and an approach to management for sepsis mimics. DISCUSSION: The current emergency medicine definition of sepsis includes SIRS, a definition that may be met by many conditions. Because of common pathophysiologic responses, these diseases present in a similar manner. These conditions include anaphylaxis, gastrointestinal emergency, pulmonary disease, metabolic abnormality, toxin ingestion/withdrawal, vasculitis, and spinal injury. Many of these conditions can be deadly if they are not diagnosed and managed. However, differentiating between sepsis and mimics can be difficult in the emergency setting. Laboratory abnormalities in isolation do not provide a definitive diagnosis. However, a combination of history, physical examination, and adjunctive studies may assist providers. For the patient in extremis, resuscitation must take precedence while attempts to differentiate sepsis from mimics are underway. CONCLUSIONS: SIRS and sepsis exist along a continuum, with many other conditions overlapping because of a common physiologic response. A combination of factors will assist providers in differentiating sepsis from mimics rather than using diagnostic studies in isolation. Resuscitation should be initiated while attempting to differentiate sepsis from its mimics. PMID- 27692841 TI - Use of High-Dose Phenylephrine in the Treatment of Ischemic Priapism: Five-Year Experience at a Single Institution. AB - INTRODUCTION: Ischemic priapism is an uncommon urologic emergency characterized by a compartment syndrome-like ischemic insult to the corpora cavernosa of the penis. The goal of treatment in ischemic priapism is rapid detumescence to prevent long-term erectile dysfunction. Non-surgical treatment options include aspiration, irrigation, and intracavernous injections of sympathomimetic agents. At our institution, phenylephrine is used in the treatment of ischemic priapism at concentrations and doses that are higher than those recommended in established guidelines. AIM: To characterize our experience with high-concentration intracavernous phenylephrine in the treatment of ischemic priapism at an urban tertiary care center. METHODS: A retrospective chart review identified 58 unique patients presenting to the emergency department on 136 occasions and receiving the diagnosis of ischemic priapism by urologic physicians. Patients' charts were reviewed to record the dosing of phenylephrine and the outcomes and circumstances of the presentation. MAIN OUTCOME MEASURES: Success rates of different treatment strategies for different circumstances of presentation. RESULTS: Successful detumescence was achieved with non-surgical management in 86% of unique patients and the overall resolution rate when including repeat visits was 94%. All patients presenting within less than 36 hours of priapism were successfully treated with non-surgical management. There were no reported complications or associated symptoms related to the use of intracavernous phenylephrine during the 5-year period. CONCLUSION: The use of high concentration and dosing of intracavernous phenylephrine demonstrates a high success rate in the treatment of ischemic priapism. Future prospective studies are needed to further characterize appropriate phenylephrine dosing for its efficacy and safety. PMID- 27692842 TI - TX-004HR Improves Sexual Function as Measured by the Female Sexual Function Index in Postmenopausal Women With Vulvar and Vaginal Atrophy: The REJOICE Trial. AB - INTRODUCTION: TX-004HR is an investigational, applicator-free, vaginal soft gel capsule containing low-dose solubilized 17beta-estradiol. The phase 3, randomized, double-blinded, placebo-controlled, multicenter REJOICE trial has shown TX-004HR to be safe and effective for the treatment of moderate to severe dyspareunia in postmenopausal women with vulvar and vaginal atrophy (VVA). AIM: To evaluate the effect of TX-004HR on female sexual dysfunction in postmenopausal women with VVA. METHODS: The REJOICE study compared the effects of 12-week treatment with TX-004HR (4, 10, or 25 MUg) with placebo in postmenopausal women (40-75 years old) with VVA and a most bothersome symptom of moderate to severe dyspareunia. Changes in the percentage of superficial and parabasal cells, vaginal pH, and dyspareunia were measured as co-primary end points. Female sexual dysfunction was evaluated as a secondary end point using the Female Sexual Function Index (FSFI) patient self-report inventory. MAIN OUTCOME MEASURES: Changes from baseline to week 12 in total and individual domain FSFI scores for each TX-004HR dose were compared with those for placebo. RESULTS: All three TX 004HR doses increased the baseline total FSFI score after 12 weeks, with 10 MUg (P < .05) and 25 MUg (P = .0019) having a significantly greater effect than placebo. A similar trend was observed for the individual FSFI domains, with 10 and 25 MUg significantly improving baselines scores for pain and lubrication at 12 weeks (P <= .015 for all vs placebo). Changes from baseline to week 12 in arousal (P = .0085) and satisfaction (P = .0073) were significantly greater for TX-004HR 25 MUg vs placebo. All three TX-004HR doses were comparable to placebo in their effect on desire and orgasm. CONCLUSION: TX-004HR improved FSFI scores in a dose-dependent manner. The observed improvements in sexual function suggest that TX-004HR is a promising treatment option for postmenopausal VVA with a potential added beneficial effect on female sexual dysfunction. PMID- 27692843 TI - Role of Body Esteem in the Sexual Excitation and Inhibition Responses of Women With and Without a History of Childhood Sexual Abuse. AB - INTRODUCTION: Women's sexuality is influenced by their perceptions of their bodies. Negative body appraisals have been implicated in the development and maintenance of sexual concerns in women with a history of childhood sexual abuse (CSA). The sexuality of these women is often expressed in extremes of approach and avoidant sexual tendencies, which have been related to the sexual inhibition and sexual excitation pathways of the dual control model. AIM: To test the influence of body esteem on the sexual excitation and inhibition responses of women with and without a history of CSA. METHODS: One hundred thirty-nine women with CSA and 83 non-abused women reported on their abuse history, depressive symptomology, sexual response, and affective appraisals of their body. MAIN OUTCOME MEASURES: Validated self-report measurements of sexual excitation and inhibition responses (Sexual Excitation/Sexual Inhibition Inventory for Women) and body esteem (Body Esteem Scale) were administered. RESULTS: Body esteem was significantly associated with sexual inhibition responses of women regardless of CSA history status but was significantly related only to the sexual excitation responses of women with a CSA history. Perceived sexual attractiveness was a unique predictor of sexual excitation in women with a history of CSA. CONCLUSION: Women with a history of CSA have lower body esteem than non-abused women, particularly in self-perceived sexual attractiveness, and these perceptions appear to influence their sexual responses by acting on the sexual excitation and inhibition response pathways. PMID- 27692844 TI - Cardiometabolic Risk and Female Sexuality: Focus on Clitoral Vascular Resistance. AB - INTRODUCTION: The relation between sexual and cardiovascular health in women is not well defined. Clitoral color Doppler ultrasound (CDU) with assessment of the pulsatility index (PI), reflecting resistance to blood flow, has been proposed as an objective measurement of sexual functioning. AIM: To investigate associations between clitoral PI and cardiometabolic risk factors, sexual and intrapsychic parameters, and self-perception of body image. METHODS: Seventy-one adult heterosexual women in a stable relationship attending our clinic for sexual dysfunction were consecutively recruited. MAIN OUTCOME MEASURES: Patients underwent physical, laboratory, and clitoral color Doppler ultrasound examinations and completed the Female Sexual Function Index, the Middlesex Hospital Questionnaire, and the Body Uneasiness Test (BUT). RESULTS: Clitoral PI was positively correlated with body mass index (r = 0.441, P < .0001), waist circumference (r = 0.474, P < .0001), glycemia (r = 0.300, P = .029), insulin (r = 0.628, P = .002), homeostatic model assessment index (r = 0.605, P = .005), triglycerides (r = 0.340, P = .011), total cholesterol (r = 0.346, P = .010), and low-density lipoprotein cholesterol (r = 0.334, P = .016). All relations, with the exception of glycemia, retained statistical significance after adjusting for age, smoking habit, and years since menopause (P < .0001 for body mass index, waist circumference, and triglycerides; P < .05 for all other associations). Analysis of covariance, after adjusting for confounders, showed that women with obesity or metabolic syndrome (MetS) showed significantly higher PI values (obesity: F = 17.79, P = .001; MetS: F = 7.37, P = .019). In particular, a stepwise increase of PI was found as a function of increasing MetS components (beta = 0.434, P = .007). Clitoral PI was negatively associated with Female Sexual Function Index arousal (beta = -0.321, P = .014) and satisfaction (beta = 0.289, P = .026) scores and positively associated with Middlesex Hospital Questionnaire somatized anxiety symptoms, even after adjusting for age, smoking habit, years since menopause, and current use of psychiatric medication (beta = 0.354, P = .011). A positive association also was observed between PI and the BUT positive symptom distress index (beta = 0.322, P = .039) and BUT for dislike of the womb, genitals, and breast (beta = 0.538, P < .0001; beta = 0.642, P < .0001; beta = 0.549, P < .0001, respectively). After introducing waist circumference as another covariate, the associations between clitoral PI and the BUT positive symptom distress index and BUT dislike of the womb, genitals, and breast retained statistical significance (P = .038 for positive symptom distress index; P < .0001 for dislike of womb, genitals, and breast). CONCLUSION: Clitoral vascular resistance is positively associated with MetS (in particular insulin resistance), decreased sexual arousal, body image concerns, and increased somatized anxiety symptoms. Further studies are needed to establish whether treatment of metabolic abnormalities might improve clitoral color Doppler ultrasound indices and sexual outcomes. PMID- 27692845 TI - Psychometric Evaluation of the Hypogonadism Impact of Symptoms Questionnaire. AB - INTRODUCTION: The Hypogonadism Impact of Symptoms Questionnaire (HIS-Q) is a patient-reported outcome measurement designed to comprehensively evaluate the symptoms of hypogonadism and to detect changes in these symptoms in response to treatment. AIM: To conduct item analysis and reduction, evaluate the psychometric properties of the HIS-Q, and provide guidance on interpreting the instrument score. METHODS: A 12-week observational, longitudinal study of hypogonadal men was conducted. Participants completed the HIS-Q every 2 weeks. Blood samples were collected to evaluate testosterone levels. Participants also completed the Aging Male's Symptoms Scale, the International Index of Erectile Function, the Short Form-12 Health Survey, and the Patient-Reported Outcomes Measurement Information System Sexual Activity, Satisfaction with Sex Life, Sleep Disturbance, and Applied Cognition Scales (at baseline and weeks 6 and 12). Clinicians completed the Clinical Global Impression of Severity and Change measurements and a clinical form. MAIN OUTCOME MEASURES: Individual item performance was evaluated using descriptive statistics and Rasch analyses. Reliability (internal consistency and test-retest), validity (concurrent and know groups), and responsiveness were assessed. RESULTS: In total, 177 men participated in the study (mean age = 54.1 years, range = 23-83). The original 53-item draft HIS-Q was reduced to 28 items; the final instrument included five domains (sexual, energy, sleep, cognition, and mood) with two sexual subdomains (libido and sexual function). For all domains, test-retest reliability was acceptable (intraclass correlation coefficients > 0.70), construct validity was good (|r > 0.30| for all comparisons). Known-groups validity was demonstrated for all HIS-Q domain scores, subdomain scores, and the total score as measured by the Clinical Global Impression of Severity, and total testosterone level at baseline (P < .05 for all comparisons). All domains and subdomains were responsive to change based on patient-rated anchor questions (P < .05 for all comparisons). CONCLUSION: The final 28-item HIS-Q is reliable, valid, and responsive. The HIS-Q is suitable for inclusion in future clinical trials to help characterize the effects of testosterone replacement therapy. PMID- 27692847 TI - Molecular complexity of taxane-induced cytotoxicity in prostate cancer cells. AB - BACKGROUND: Taxanes are routinely used to treat men with advanced prostate cancer, yet their molecular mode of action is poorly characterized. Taxanes stabilize microtubules and may hence interfere with a plethora of cellular processes, most notably mitosis. However, prostate cancer is typically a slowly growing tumor suggesting that additional processes play a role in the response to taxanes. METHODS: Here, we analyzed the potential effect of taxanes on microtubuli-dependent intracellular transport and signaling processes, specifically, nuclear translocation of the androgen receptor and modulation of the RAS-RAF-MEK-ERK signaling cascade. RESULTS: We show that the androgen-driven nuclear translocation of the androgen receptor remains virtually undisturbed by docetaxel in prostate cancer cells. However, we found a striking down-regulation of activated ERK1/2 together with enhanced cytotoxicity in both docetaxel or cabazitaxel-treated cells that was comparable to direct MEK kinase inhibition. Remarkably, MEK inhibition alone was less effective in inducing cytotoxicity than taxanes indicating that a down-regulation of activated ERK1/2 may be necessary but is not sufficient for taxane-induced antitumoral effects. In line with this notion, we show in a xenograft mouse model that prostate cancer cells that are resistant to docetaxel overexpress activated ERK1/2. Taken together, our findings underscore that the modulation of ERK1/2 activation, in concert with other mechanisms, plays an important role in taxane-induced antineoplastic effects on prostate cancer cells. CONCLUSIONS: These results suggest at least partially nonoverlapping effects of docetaxel and androgen deprivation therapy and hence help to understand recent clinical findings. A further elucidation of the mode of action of docetaxel would have important implications to optimize current treatment strategies and biomarker development for men with metastatic prostate cancer. PMID- 27692846 TI - The structural connectivity of higher order association cortices reflects human functional brain networks. AB - Human higher cognition arises from the main tertiary association cortices including the frontal, temporal and parietal lobes. Many studies have suggested that cortical functions must be shaped or emerge from the pattern of underlying physical (white matter) connectivity. Despite the importance of this hypothesis, there has not been a large-scale analysis of the white-matter connectivity within and between these associative cortices. Thus, we explored the pattern of intra- and inter-lobe white matter connectivity between multiple areas defined in each lobe. We defined 43 regions of interest on the lateral associative cortex cytoarchitectonically (6 regions of interest - ROIs in the frontal lobe and 17 ROIs in the parietal lobe) and anatomically (20 ROIs in the temporal lobe) on individuals' native space. The results demonstrated that intra-region connectivity for all 3 lobes was dense and graded generally. In contrary, the inter-lobe connectivity was relatively discrete and regionally specific such that only small sub-regions exhibited long-range connections to another lobe. The long range connectivity was mediated by 6 major associative white matter tracts, consistent with the notion that these higher cognitive functions arises from brain-wide distributed connectivity. Using graph-theory network analysis we revealed five physically-connected sub-networks, which correspond directly to five known functional networks. This study provides strong and direct evidence that core functional brain networks mirror the brain's structural connectivity. PMID- 27692848 TI - Changes in expressions of ADAM9, 10, and 17 as well as alpha-secretase activity in renal cell carcinoma. AB - BACKGROUND: ADAM9, 10, and 17 are a class of disintegrins and metallproteinases with alpha-secretase activity. There are conflicting results regarding the role(s) of ADAM9, 10, and 17 in carcinogenesis, and only a few studies have examined their levels and cellular localization in renal cell carcinoma (RCC). Studies examining changes in alpha-secretase activity in RCC compared to enzymatic activity of the uninvolved kidney are lacking. METHOD: A cross sectional study was conducted in 56 patients undergoing radical nephrectomy after the diagnosis of RCC. alpha-Secretase activity was determined using flourogenic substrate in freshly frozen tumor tissues as well as similarly treated tissues from the neighboring kidney. Immunohistochemical analyses of ADAM9, 10, and 17 were also performed. RESULTS: alpha-Secretase activity decreased markedly in all types of RCC as compared to neighboring uninvolved kidney tissue having 5 to 10 times higher levels of alpha-secretase activity. Although type-dependent variations were observed, tumoral expressions of ADAMs, except for ADAM17, were lower in the tumors compared to that of neighboring tissues, but the changes in alpha-secretase activity were greater. In RCC tissue, ADAM9 expressions were localized in nuclear and cytoplasmic compartments, whereas ADAM10 and 17 were present predominately in the cytoplasm potentially explaining the markedly decreased enzyme activity. Membranous localization of ADAMs was noted in uninvolved kidney tissue. CONCLUSIONS: The loss of alpha-secretase activity observed here in conjunction with previous findings argue against tumorigenic effects of ADAM9, 10, and 17 supporting that increased nuclear and cytoplasmic expression may be an attempt to compensate for loss of function. PMID- 27692850 TI - HbA1c as a predictor of diabetes after gestational diabetes mellitus. AB - AIM: We wanted to investigate third-trimester HbA1c as a predictor of diabetes after gestational diabetes mellitus (GDM). METHODS: Women with GDM were followed up prospectively for five years from pregnancy to detect the development of diabetes. The ability of HbA1c to predict diabetes was evaluated with receiver operating characteristic (ROC) curves and logistic regression analysis. RESULTS: By five years, 73 of 196 women had been diagnosed with diabetes. An optimal cut off point for HbA1c of 36mmol/mol (5.4%) could predict diabetes with 45% sensitivity and 92% specificity. For HbA1c >=39mmol/mol (>=5.7%), sensitivity, specificity, and positive predictive value were 30%, 97%, and 91%, respectively. In logistic regression analysis, adjusting for the diagnostic glucose concentration during pregnancy, HbA1c levels in the upper quartile (>=36mmol/mol) were associated with a 5.5-fold increased risk of diabetes. CONCLUSION: Third trimester HbA1c levels in the pre-diabetes range revealed women with post-partum diabetes with high specificity and high positive predictive value. HbA1c testing could be used as a strategy to select high-risk women for lifestyle interventions aimed at prevention of diabetes starting during pregnancy. The results should encourage further validation in other populations using new diagnostic criteria for GDM. PMID- 27692851 TI - Bilateral mammoplasty for cancer: Surgical, oncological and patient-reported outcomes. AB - INTRODUCTION: Bilateral mammoplasty (BM) can optimise oncological safety and aesthetic outcomes in women with large or ptotic breasts whose tumour to breast volume ratio or tumour location pose a challenge to standard breast-conserving therapy (BCT) and for whom mastectomy (with or without reconstruction) may be the only alternative. METHODS: We undertook a comprehensive analysis of surgical outcomes (complications according to the Clavien Dindo classification), acute radiation morbidity (Radiation Therapy Oncology Group classification), oncological outcomes, and patient satisfaction (BREAST-Q questionnaire) in women who underwent BM for breast cancer (BC) from June 2009-November 2014. RESULTS: 168 women were included. Median age was 55 years (range:33-84) and median tumour size at imaging 35 mm (range:0-170). Median specimen weight was 242 g (range 39 1824). The wise pattern technique was used in 87.5% of procedures. At least one complication occurred in 68 (40.5%) women, mostly Clavien Dindo grade 1. Grade 3 complications were infrequent (8.9%) but occurred mainly on the therapeutic mammoplasty (TM) side (p < 0.05). Complications were associated with higher BMI, specimen weight and longer time to radiotherapy (p < 0.05). Median follow-up was 37 months (range: 13-77). Local recurrence occurred in 3 (1.8%), distant metastases in 5 (3.0%), and 10 (6.0%) women have died. The median score for 'satisfaction with breasts' was 77 (range: 0-100). CONCLUSIONS: This study provides concurrent data on surgical, oncological and patient-reported outcomes. It offers evidence that BM is an effective treatment for breast cancer in large- or ptotic-breasted women. PMID- 27692852 TI - Pragmatic Language Interpretation as Probabilistic Inference. AB - Understanding language requires more than the use of fixed conventions and more than decoding combinatorial structure. Instead, comprehenders make exquisitely sensitive inferences about what utterances mean given their knowledge of the speaker, language, and context. Building on developments in game theory and probabilistic modeling, we describe the rational speech act (RSA) framework for pragmatic reasoning. RSA models provide a principled way to formalize inferences about meaning in context; they have been used to make successful quantitative predictions about human behavior in a variety of different tasks and situations, and they explain why complex phenomena, such as hyperbole and vagueness, occur. More generally, they provide a computational framework for integrating linguistic structure, world knowledge, and context in pragmatic language understanding. PMID- 27692849 TI - Calcium at the Center of Cell Signaling: Interplay between Endoplasmic Reticulum, Mitochondria, and Lysosomes. AB - In recent years, rapid discoveries have been made relating to Ca2+ handling at specific organelles that have important implications for whole-cell Ca2+ homeostasis. In particular, the structures of the endoplasmic reticulum (ER) Ca2+ channels revealed by electron cryomicroscopy (cryo-EM), continuous updates on the structure, regulation, and role of the mitochondrial calcium uniporter (MCU) complex, and the analysis of lysosomal Ca2+ signaling are milestones on the route towards a deeper comprehension of the complexity of global Ca2+ signaling. In this review we summarize recent discoveries on the regulation of interorganellar Ca2+ homeostasis and its role in pathophysiology. PMID- 27692853 TI - 1,10-Phenanthroline and its derivatives are novel hatching stimulants for soybean cyst nematodes. AB - Soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is a plant-parasitic nematode and one of the most serious soybean pests. Herein, we present the heterocyclic compound 1,10-phenanthroline (Phen) and its derivatives as novel hatching stimulants for SCN. Phen treatment promoted hatching of second-stage juveniles of SCNs in a concentration-dependent manner. In addition, the hatching of SCNs following treatment with Phen occurred more rapidly than that following treatment with the known hatching stimulant, glycinoeclepin A (GEA). Furthermore, the co-application of Phen and GEA enhanced SCN hatching rate compared with that of Phen or GEA alone. A structure-activity relationship study for Phen derivatives suggested that 2,2'-bipyridine is the essential structure of the SCN hatching stimulants. These results suggest that Phen and its derivatives activate different hatching pathways of SCNs from GEA. PMID- 27692854 TI - N-Arylsulfonyl-alpha-amino carboxamides are potent and selective inhibitors of the chemokine receptor CCR10 that show efficacy in the murine DNFB model of contact hypersensitivity. AB - Compound 1 ((4-amino-3,5-dichlorophenyl)-1-(4-methylpiperidin-1-yl)-4-(2 nitroimidazol-1-yl)-1-oxobutane-2-sulfonamido) was discovered to be a 690nM antagonist of human CCR10 Ca2+ flux. Optimization delivered (2R)-4-(2-cyanopyrrol 1-yl)-S-(1H-indol-4-yl)-1-(4-methylpiperidin-1-yl)-1-oxobutane-2-sulfonamido (eut 22) that is 300 fold more potent a CCR10 antagonist than 1 and eliminates potential toxicity, mutagenicity, and drug-drug-interaction liabilities often associated with nitroaryls and anilines. eut-22 is highly selective over other GPCR's, including a number of other chemokine receptors. Finally, eut-22 is efficacious in the murine DNFB model of contact hypersensitivity. The efficacy of this compound provides further evidence for the role of CCR10 in dermatological inflammatory conditions. PMID- 27692855 TI - Systematic Review and Single-Center Experience for Endovascular Management of Visceral and Renal Artery Aneurysms. AB - PURPOSE: To report a systematic review of endovascular management of visceral and renal artery aneurysms (VRAA) and results at a tertiary referral center. MATERIALS AND METHODS: A literature review was performed via a comprehensive electronic search of PubMed, MEDLINE, EMBASE, and Cochrane databases, followed by retrospective analysis of all VRAAs treated at a tertiary referral center from January 1999 to December 2015. RESULTS: The systematic review included 22 studies published between 2005 and 2016 describing endovascular treatment of VRAA. In the systematic review cohort, 646 aneurysms (432 true, 151 false, 63 unclassified) were treated using endovascular methods with 93.2% technical success, 99.3% visceral preservation, 3.5% major complication (classified based on Society of Interventional Radiology criteria), 1.5% 30-day periprocedural mortality, and 4.6% reintervention rates. In the local cohort, 19 aneurysms (12 true, 7 false) were treated with 100% technical success, 94.7% visceral preservation, and 10.5% major complication rates. There was no periprocedural mortality. Over mean follow up of 31.9 months (range, 2-170 months), there were 2 aneurysm reperfusions, which required no further treatment. Results incorporating data from the systematic review and local cohorts (665 aneurysms) showed 93.6% technical success, 99.1% visceral preservation, 3.7% major complication, 1.5% periprocedural mortality, and 4.4% reintervention rates. CONCLUSIONS: Endovascular treatment of VRAA is associated with excellent technical success and visceral preservation rates. Major complication and periprocedural mortality rates are comparatively low. A few VRAA (4.4%) required future reintervention suggesting that imaging follow-up is essential after initial treatment. PMID- 27692856 TI - The Effect of Bridging Locoregional Therapy and Sociodemographics on Survival in Hepatocellular Carcinoma Patients Undergoing Orthotopic Liver Transplantation: A United Network for Organ Sharing Population Study. AB - PURPOSE: To investigate socioeconomic and demographic factors associated with transplantation outcomes in patients with hepatocellular carcinoma (HCC) treated with bridging locoregional therapy (LRT) before orthotopic liver transplantation (OLT). MATERIALS AND METHODS: The United Network for Organ Sharing (UNOS) database was used to identify all patients in the United States with HCC who were listed for OLT between 2002 and 2013. Mean overall survival (OS) after OLT was stratified based on age, sex, ethnicity, transplant year, region, and insurance status. Kaplan-Meier estimation was used for survival analysis with log-rank test and Cox proportional hazards model to assess independent prognostic factors for OS. RESULTS: Of the 17,291 listed patients with HCC, 14,511 underwent OLT. Mean age was 57.4 years (76.8% male). Favorable sociodemographic factors were associated with increased rates of bridging LRT before OLT and longer wait time on the transplant list and were shown to be independent prognostic factors for prolonged OS after OLT using multivariate analysis. Favorable demographic factors included patient age < 60 years, donor age < 45 years, year of diagnosis between 2008 and 2013, UNOS regions 4 and 5, Asian ethnicity, high functional status, postgraduate education, private payer insurance, and employment at the time of OLT. CONCLUSIONS: Patients with favorable sociodemographics had higher rates of LRT before OLT performed for HCC cure. These patients had longer transplant wait times and longer OS after OLT. PMID- 27692858 TI - On the stability of gold nanoparticles synthesized by laser ablation in liquids. AB - "Naked" gold nanoparticles (AuNPs), synthesized in the absence of any capping agents, prepared by pulsed laser ablation in liquid (PLAL) are stabilized by negative charges. Common explanations for this phenomenon involve the presence of gold oxides and/or the anion adsorption. We have found that AuNP ablated in solutions of acids with very different oxidation power, viz. HCl, H2SO4, HNO3 share the same size and zeta-potential. Although, gold oxides have pKas~4, the zeta-potential of AuNPs ablated in solutions with pH?4 is always negative. These evidences suggest that the gold oxidation and anion adsorptions have only a minor role on building the negative surface potential and we hypothesize, for the first time, that excess electrons formed within the plasma phase could charge the metallic particles. In our model, a crucial point is that the colloidal size of the NP maintains the energy of the electrons small enough to preclude chemical reactions but with a surface potential yet large enough to stabilize the AuNPs with respect to aggregation. A confirmation of the hypothesis of "electron stabilized nanoparticles" is that either the addition of macroscopic metallic objects either the contact with a "grounded" copper wire induce the loss of charge and AuNPs aggregation. PMID- 27692857 TI - Insights into the central pathways involved in the emetic and behavioural responses to exendin-4 in the ferret. AB - BACKGROUND: GLP-1 receptor agonists are utilised for the treatment of Type-2 diabetes but can be associated with undesirable effects of nausea and vomiting. OBJECTIVES: To investigate the role of GLP-1 receptors in mechanisms of emesis, behaviours indicative of nausea (BIN) and food intake in the ferret. RESULTS: Exendin-4 (10 and 30nmol, i.c.v.) induced emesis, inhibited food intake, and increased the frequency of BIN. Increases in c-Fos in the brainstem, midbrain and forebrain occurred in animals exhibiting emesis; no activation of the brainstem occurred in animals not vomiting. Exendin-4 (10nmol, i.c.v.) when preceded by i.c.v. saline (15MUl), was not emetic but induced BIN and inhibited food intake; exendin (9-39) (100nmol) reduced BIN only. c-Fos showed that consistent with the absence of emesis in saline/exendin-4 treated animals there was no increase in c Fos in the brainstem, but it increased in midbrain and forebrain nuclei. Excepting the amygdala, exendin (9-39) was without efffect on the increases in c Fos. Analysis of c-Fos data showed a positive linear relationship between midbrain and forebrain areas irrespective of the occurrence of emesis induced by exendin-4. In contrast, brainstem and midbrain c-Fos levels were positively correlated, but only in animals with emesis. CONCLUSIONS: The brainstem is critical for exendin-4-induced emesis but suppression of food intake and BIN involves more rostral brain sites. Exendin-4-induced BIN and c-Fos activation of the amygdala are sensitive to exendin (9-39), whereas the suppression of food intake is not implicating separate control mechanisms for emesis and BIN. PMID- 27692859 TI - Unusually High Calcaneal Speed of Sound Measurements in Children with Small Foot Size. AB - The purpose of this clinical note is to describe the performance of the Lunar Achilles Insight device in assessing bone quality at the calcaneus in 142 children between the ages of 5 and 11 y accessing healthcare in Johannesburg, South Africa. We observed an asymmetric bimodal distribution in speed of sound (SOS). The minor mode consisted of unusually high SOS values (>=1625 m/s), which were primarily observed among children with foot size <19 cm and height <119 cm. Cortical regions of the bone may have been inadvertently included in the region of interest for smaller feet, causing unusually high SOS values. The unusually high SOS values indicate that the validity of SOS in this device, as it is currently used for measuring bone quality in young children, is questionable. Future studies using this device in young children should develop new methodology to account for smaller foot size. PMID- 27692860 TI - Pulmonary Arterial Hypertension after Ibuprofen Treatment for Patent Ductus Arteriosus in Very Low Birth Weight Infants. AB - OBJECTIVE: To describe the clinical course and risk factors for pulmonary arterial hypertension (PAH) after ibuprofen treatment to close patent ductus arteriosus. STUDY DESIGN: All neonates weighing < 1500 g at birth who received ibuprofen to close patent ductus arteriosus and were admitted to Seoul National University Children's Hospital's neonatal intensive care unit in 2010-2014 were eligible for this study. The study population was divided into the PAH and non PAH groups, and medical records were retrospectively reviewed. RESULTS: Of the 144 eligible infants, 10 developed PAH (6.9%). Relative to the non-PAH group, the PAH group exhibited greater respiratory severity and more frequent severe bronchopulmonary dysplasia or death before 36 weeks postmenstrual age. Multivariable analysis demonstrated that lower gestational age, birth weight in less than the third percentile for age, maternal hypertension of pregnancy, and oligohydramnios were risk factors for developing PAH after ibuprofen treatment. CONCLUSION: A high incidence of PAH after ibuprofen treatment was observed in the study population. Furthermore, younger gestational age and several prenatal conditions were identified as risk factors for developing PAH after ibuprofen treatment. Additional large cohort studies are necessary to confirm our results. PMID- 27692862 TI - Opportunities to finance pandemic preparedness. PMID- 27692861 TI - Effect of Severity of Esophageal Acidification on Sleep vs Wake Periods in Infants Presenting with Brief Resolved Unexplained Events. AB - OBJECTIVES: To describe the pattern of gastroesophageal reflux (GER) events in wake and sleep states with increasing acid reflux index (ARI) in neonates and to test the hypothesis that GER-related symptoms are frequent in ARI >7% in wake state. STUDY DESIGN: Infants underwent 24-hour pH-impedance studies with 6-hour concurrent video-polysomnography studies. Data were stratified based on the 24 hour ARI (% duration that esophageal pH is <4) into ARI < 3% (normal), ARI 3 >= to <=7% (intermediate), and ARI >7% (abnormal). GER frequency, clearance mechanisms, and symptoms were distinguished during wake state and sleep state. RESULTS: Total wake and sleep duration was similar (P >= .2) in all ARI groups. Acidic events were frequent with increasing ARI in wake state vs sleep state (P <= .03). The symptom index increased with increasing ARI (P <= .02) in both wake state and sleep state. Acid clearance time increased with increasing ARI in wake state (P <= .02). In ARI > 7% vs ARI <= 7%, frequency of acidic GER events was higher (P <= .02) in wake state and sleep state; proximal migration of acid (P = .03) and acid clearance time were higher in wake state (P = .0005) only. Symptom index was higher in ARI >7% vs ARI <= 7% in wake state (P < .0001), comparable in normal vs intermediate (P = .4), and higher in abnormal vs intermediate (P = .0004) groups. CONCLUSIONS: Severe esophageal acid exposure (ARI >7%) is associated with increased reflux-associated symptoms in wake state. Sleep state appears to be protective regardless of ARI, likely because of greater chemosensory thresholds. Attention to posture and movements during wake state can be helpful. Scrutiny for non-GER etiologies should occur for infants presenting with life-threatening symptoms. PMID- 27692863 TI - Spring-mediated distraction enterogenesis in-continuity. AB - PURPOSE: Distraction enterogenesis has been investigated as a novel treatment for patients with short bowel syndrome (SBS) but has been limited by loss of intestinal length during restoration and need for multiple bowel surgeries. The feasibility of in-continuity, spring-mediated intestinal lengthening has yet to be demonstrated. METHODS: Juvenile mini-Yucatan pigs underwent in-continuity placement of polycaprolactone (PCL) degradable springs within jejunum. Methods used to anchor the spring ends to the intestine included full-thickness sutures and a high-friction surface spring. Spring constant (k) was 6-15N/m. Bowel was examined for length and presence of spring at 1 to 4weeks. RESULTS: Animals tolerated in-continuity lengthening without bowel obstruction for up to 29days. In-continuity jejunum with springs demonstrated intestinal lengthening by 1.47 fold +/-0.11. Five springs had detached prematurely, and lengthening could not be assessed. Histologically, in-continuity jejunum showed significantly increased crypt depth and muscularis thickness in comparison to normal jejunum. CONCLUSION: Self-expanding endoluminal springs placed in continuity could lengthen intestine without obstruction in a porcine model. This is the first study showing safety and efficacy of a self-expanding endoluminal device for distraction enterogenesis. This is proof-of-concept that in-continuity spring lengthening is feasible and demonstrates its therapeutic potential in SBS. LEVEL OF EVIDENCE: Level 3. PMID- 27692864 TI - Saturation of stool color in HSV color model is a promising objective parameter for screening biliary atresia. AB - PURPOSE: We aimed to study whether saturation in HSV color model could be a parameter for acholic stool and utilized for designing a mobile application for screening biliary atresia (BA). METHODS: Saturations of the colors in the three validated stool color cards (Taiwan, Japan, Britain) were read using PHOTOSHOP. Stools from 40 BA patients and 40 in-hospital neonates with pneumonia were photographed and analyzed with color-analyzing mobile applications. RESULTS: Saturations of normal colors in the published stool cards were all >50% (67%~99%, median 85%) and were all <50% (7~47%, median 25%) for abnormal colors. With saturation<60% as a cutoff line, acholic stools could be identified with a sensitivity of 100% and a specificity of 85%. CONCLUSION: Saturation of stool color in HSV model is a promising objective parameter for acholic stool and could be utilized in designing mobile APPs for screening BA. LEVEL OF EVIDENCE: Study of diagnostic test, level II. PMID- 27692865 TI - Clinical manifestation of late onset Pompe disease patients in Hong Kong. AB - Late onset Pompe disease is a rare inherited metabolic disease with diverse clinical manifestation. However, there is a lack of local data in Hong Kong. We aimed at performing an in-depth review of natural history of all patients in Hong Kong. Eleven patients were diagnosed to have the disease in Hong Kong from 2000 to 2013. All case records were reviewed and face-to-face interviews were conducted to complete a questionnaire regarding the clinical manifestation and diagnosis of the disease. The estimated birth incidence was 1/300,000. The age of diagnosis ranged from 9 to 44 years; all patients were ethnic Chinese. The median ages of first symptoms and first medical attention were 20.5(6-44) and 29(9-44) years respectively. The most common initial complaint was decreased exercise tolerance. Two patients' first complaint was difficulty with getting up from lying position and failure to perform sit up. The mean time from first medical attention to diagnosis was 1.3 years but one patient was diagnosed 8 years later. Half of the patients sought medical attention due to progressive shortness of breath and all of them developed type 2 respiratory failure requiring ventilator support during the first admission. Two patients became chair-bound and seven patients required assisted ventilation. Late onset Pompe disease tends to have an earlier and more aggressive clinical presentation in Chinese and lower birth incidence was found in Hong Kong. PMID- 27692866 TI - Coronal alignment on the single-limb stance radiograph in posterolateral rotatory instability, osteoarthritis and healthy knees. AB - BACKGROUND: We aimed to determine whether coronal alignment measured on the single-limb stance (SLS) radiographs differs from those on the double-limb stance (DLS) images. We also investigated whether the size of such differences was affected by the knee pathology, lower limb alignment, and geometry of the tibia or femur. METHODS: We measured coronal alignment with mechanical tibiofemoral angle (MTFA) on the DLS and SLS radiographs in patients with posterolateral rotatory instability (PLRI, 30 knees), osteoarthritis (OA) with varus deformity who were scheduled for high tibial osteotomy (HTO) (60 knees), and in normal control (60 knees). The measurements on the SLS radiographs were compared with those on DLS images and the size of the differences were compared between the three groups. The correlation between the radiograph-related differences of coronal alignment and the limb alignment or geometry of tibia/femur was investigated. In the OA group, the size of the radiograph-related differences before HTO were compared with those after surgery. RESULTS: The coronal alignment on the SLS radiographs indicated varus accentuation compared to those on the DLS radiographs in the PLRI and OA groups (1.6 and 2.4 degrees , respectively), while it was negligible in the normal group. Greater varus inclination of the tibial plateau was related to greater varus accentuation (r=0.249). The HTO decreased the extent of varus accentuation in the OA group (reduction of varus accentuation=1.5 degrees ). CONCLUSIONS: Coronal alignment on the SLS radiograph is different from static alignment measured on the DLS radiograph, which may reflect dynamic alignment. PMID- 27692867 TI - Targeting Single Molecules in Asthma Benefits Few. AB - Asthma is a lung disorder triggered by various airborne factors in susceptible individuals. Although generally controlled, asthma can be severe and difficult to treat. Presently, increasing numbers of pharmaceuticals capable of blocking or mimicking specific endogenous molecules are undergoing clinical trials in asthmatic individuals whose symptoms are poorly controlled despite adherence to guideline therapies. Unfortunately, only a few, meticulously selected patients have been found to minimally benefit. These findings not only confirm that the molecular pathogenesis of severe asthma is variable between patients but also suggest that each molecular defect is likely to contribute little on its own in each patient. We opine that therapies targeting a specific molecular defect are predestined to yield marginal effects in the treatment of severe asthma. PMID- 27692868 TI - Chronic hypoxaemia as a molecular regulator of fetal lung development: implications for risk of respiratory complications at birth. AB - Exposure to altered intrauterine conditions during pregnancy influences both fetal growth and organ development. Chronic fetal hypoxaemia is a common pregnancy complication associated with intrauterine growth restriction (IUGR) that may influence the risk of infants experiencing respiratory complications at birth. There are a variety of signalling pathways that contribute to normal fetal lung development at the molecular level. The specific molecular effects of chronic hypoxaemia associated with IUGR on lung development are likely to be dependent on the specific aetiology (maternal, placental and/or fetal factors) that can alter hormone concentrations, oxygen and nutrient transport to the fetus. This review discusses molecular pathways that may contribute to altered fetal lung maturation following exposure to chronic hypoxaemia. Importantly, these studies highlight that the heterogeneity in respiratory outcomes at birth in this obstetric subpopulation are likely determined by the timing, severity and duration of chronic hypoxaemia encountered by the fetus during pregnancy. PMID- 27692869 TI - Understanding pharmacist success in practice: A scoping review. AB - OBJECTIVES: The objective was to identify literature providing a description of characteristics contributing to pharmacists' individual level success in providing advanced patient care. DESIGN: An interpretive scoping review was conducted to synthesize knowledge and address the study objective. SETTING: Searches were undertaken in Ovid MEDLINE (1946-2015), EMBASE (1974-2015), and International Pharmaceutical Abstracts (1970-2015). PARTICIPANTS: Not applicable. MAIN OUTCOME MEASURES: Specific keywords used in the search included: motivation, attitude, career, clinical competence, certification, pursuit of an expanded scope of practice, pharmacist, and success. This was not intended to be an exhaustive list, and every effort was made to be inclusive as the search revealed additional words and phrases of interest. RESULTS: A total of 93 articles were initially identified, 10 articles met inclusion criteria and were retained for full-text analysis. Most of the included articles were published in the United States (70%). One-third of the articles conducted semi-structured interviews, one third of the articles were editorials or commentaries, and the remaining articles collected data using surveys, knowledge assessments, and observation. Content analysis of the extracted definitions of success yielded 2 themes; "what successful pharmacists do" and "what successful pharmacists should be." CONCLUSION: Professional organizations representing pharmacy have made significant strides in advocating for pharmacists' provision of advanced patient care. If pharmacists are to successfully provide advanced patient care a more specific and practically-oriented understanding that accounts for individual and environmental factors of how to achieve individual-level success is needed. PMID- 27692870 TI - Valued characteristics of community pharmacy residency applicants. AB - OBJECTIVES: To determine the attributes of postgraduate year 1 (PGY1) community pharmacy residency applicants and candidates that are most appealing to community residency program directors (CRPDs). DESIGN: A 22-question online survey, designed to collect residency demographics, desirable characteristics for consideration for interview invitation (applicants), and characteristics that should be displayed during an interview (candidates). SETTING: American Society of Health-System Pharmacists (ASHP)-recognized community pharmacy residency programs (CPRPs). PARTICIPANTS: The CRPDs of 109 ASHP-recognized CPRPs throughout the United States. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Minimum applicant requirements; rank order of valued characteristics at application and interview stage of hiring process. RESULTS: The response rate was 71/109 (65.1%). Applicant work experience in chain pharmacy (90.1%) and independent pharmacy (77.5%) was most highly valued by CRPDs, with 85.9% preferring applicants with a minimum of 1 year or more of community pharmacy experience. A large majority of CPRPs (91.4%) indicated a preference for applicants who have been an officer of a student organization. Among CPRPs that required minimum grade point averages (GPAs), a mean GPA of 2.88 +/- 0.34 was reported (range 2.0 to 3.5; mode 3.0). Pharmacy work experience (68.1%) and letters of recommendation (59.4%) were most frequently cited as top factors in the decision-making process for selecting candidates to interview. At the interview stage, CRPDs rated interest and knowledge about the residency (62.3%), time management and prioritization (50.7%), and self-awareness and commitment to improvement (43.5%) as the most important skills for candidates to demonstrate. CONCLUSION: Community pharmacy work experience, organizational leadership experience, and positive letters of recommendation appear to be the most valued attributes of a community pharmacy residency applicant. Applicants should consider aligning themselves with these characteristics to successfully match to a community pharmacy residency.

AB - BACKGROUND: Williams syndrome (WS) is known for its uneven cognitive abilities, especially the difficulty in visuo-spatial cognition, though there are some inter individual phenotypic differences. It has been proposed that the difficulty in visuo-spatial cognition of WS patients can be attributed to a haploinsufficiency of some genes located on the deleted region in 7q11.23, based on an examination of atypical deletions identified in WS patients with atypical cognitive deficits. According to this hypothesis, the inter-individual differences in visuo-spatial cognitive ability arise from variations in deletion. METHODS: We investigated whether there were inter-individual differences in the visuo-spatial constructive abilities of five unrelated WS patients with the typical deletion on chromosome 7q11.23 that includes the candidate genes contributing visuo-spatial difficulty in WS patients. We used tests with three-dimensional factors such as Benton's three-dimensional block construction test, which are considered to be more sensitive than those with only two-dimensional factors. RESULTS: There were diverse inter-individual differences in the visuo-spatial constructive abilities among the present participants who shared the same typical genomic deletion of WS. One of the participants showed almost equivalent performances to typically developing adults in those tests. CONCLUSION: In the present study, we found a wide range of cognitive abilities in visuo-spatial construction even among the patients with a common deletion pattern of WS. The findings suggest that attributing differences in the phenotypes entirely to genetic factors such as an atypical deletion may not be always correct. PMID- 27692873 TI - Detection and Removal of Ceramic Clip Markers from Breast Tissue by Ultrasound Guided, Vacuum-Assisted Minimally Invasive Biopsy in a Turkey Breast Model. AB - This article explores the ability of sonographically guided, vacuum-assisted minimally invasive biopsy (VAB) to detect and remove ceramic clip markers from breast tissue. This is a feasibility pre-study for a clinical study using vacuum assisted biopsy to predict pathologic complete response of breast cancer. Twenty six ceramic clip markers were placed in five turkey breasts. Clip markers were then detected sonographically and removed using VAB by experienced physicians. Quality of visibility was graded by the performing doctors. The specimens were examined macroscopically to see if they contained the clip marker. The main outcome measure was the accuracy of VAB to detect and remove the clip marker. The VAB device was inspected for any damage possibly caused by hitting the clip marker. The clip markers were detected in 25 cases (96.2%). Twenty clip markers (76.9%) were removed completely by VAB and five (19.2%) were partially removed. One clip marker (3.8%) was not removed. On average, detection of the clip marker took 67 s and the biopsy took 178 s. Quality of visibility was mostly graded as very good (14 cases/53.8%) or good (nine cases/34.6%), and in all of these cases the clip marker was at least partially removed. The clip marker was visible and removed in the vast majority of the cases. VAB is able to remove the clip marker in integrity without causing damage to the system. PMID- 27692872 TI - Using Speed of Sound Imaging to Characterize Breast Density. AB - A population of 165 women with negative mammographic screens also received an ultrasound tomography (UST) examination at the Karmanos Cancer Institute in Detroit, MI. Standard statistical techniques were employed to measure the associations between the various mammographic- and UST-related density measures and various participant characteristics such as age, weight and height. The mammographic percent density (MPD) was found to have similar strength associations with UST mean sound speed (Spearman coefficient, rs = 0.722, p < 0.001) and UST median sound speed (rs = 0.737, p < 0.001). Both were stronger than the associations between MPD with two separate measures of UST percent density, a k-means (rs = 0.568, p < 0.001) or a threshold (rs = 0.715, p < 0.001) measure. Segmentation of the UST sound speed images into dense and non-dense volumes showed weak to moderate associations with the mammographically equivalent measures. Relationships were found to be inversely and weakly associated between age and the UST mean sound speed (rs = -0.239, p = 0.002), UST median sound speed (rs = -0.226, p = 0.004) and MPD (rs = -0.204, p = 0.008). Relationships were found to be inversely and moderately associated between body mass index (BMI) and the UST mean sound speed (rs = -0.429, p < 0.001), UST median sound speed (rs = 0.447, p < 0.001) and MPD (rs = -0.489, p < 0.001). The results confirm and strengthen findings presented in previous work indicating that UST sound speed imaging yields viable markers of breast density in a manner consistent with mammography, the current clinical standard. These results lay the groundwork for further studies to assess the role of sound speed imaging in risk prediction. PMID- 27692874 TI - Comparison between Quantitative Stiffness Measurements and Ultrasonographic Findings of Fresh Carotid Plaques. AB - Using a stiffness meter, we quantitatively measured the stiffness of fresh plaques that had been excised by carotid endarterectomy. The objective of this study was to clarify the correlation between plaque stiffness and pre-operative carotid ultrasonographic findings, and predict the stiffness of plaques before surgery by comparison with the stiffness of common items. The study population comprised 44 patients (44 lesions) who had undergone carotid endarterectomy at our institution between December 2009 and October 2014. The stiffness of excised fresh plaques was measured using a stiffness meter and compared with the pre operative echographic findings for the plaques and the stiffness of selected foods and common items. The mean stiffness value for all plaques was 4.52 +/- 3.30 MPa (mean +/- standard deviation). The plaques exhibiting calcification were significantly harder (p = 0.001). On classification of lesions on the basis of echographic findings, plaque hardness was in the order low-echoic (15 lesions) < iso-echoic (20 lesions) < high-echoic (9 lesions) (p = 0.02). The stiffness of the low-echoic group was equivalent to that of tofu or sliced cheese, whereas the plaques in the iso- and high-echoic groups exhibited stiffness similar to that of ham and a plastic eraser, respectively. A significant correlation was observed between the quantitative stiffness values of carotid plaques and their brightness on carotid ultrasonography. Using these data, operators might be able to predict plaque stiffness from pre-operative echographic findings. In addition, it might be useful for operators to compare such quantitative stiffness measurements with stiffness data for foods and common items to gain an understanding of the state of the target plaque before treatment. PMID- 27692875 TI - Bioactive molecules derived from umbilical cord mesenchymal stem cells. AB - Umbilical cord mesenchymal stem cells (UCMSCs) retain their intrinsic stem cell potential while at the same time displaying high proliferation rates, powerful differentiation capacity, and low immunogenicity. They can also secrete multiple bioactive molecules that exert specific physiological functions. Thus, UCMSCs represent excellent candidates for cell therapy in regenerative medicine and tissue engineering. Abundant preclinical research on different disease models has shown that UCMSCs can accelerate wound or nerve damage recovery and suppress tumor progression. In fact, UCMSCs are thought to possess a higher therapeutic potential than MSCs derived from other tissues. Increasing evidence suggests that the mechanism underlying UCSMCs efficacy depends mostly on cell secretions, in contrast to the early paradigm of cell replacement and differentiation. In this review, we discuss UCMSCs biological characteristics, their secretome-based therapeutic mechanism, and potential applications. PMID- 27692876 TI - Expression of nitric oxide-containing structures in the rat carotid body. AB - The carotid body (CB) is a major peripheral arterial chemoreceptor organ that evokes compensatory reflex responses so as to maintain gas homeostasis. It is dually innervated by sensory fibers from petrosal ganglion (PG) neurons, and autonomic fibers from postganglionic sympathetic neurons of the superior cervical ganglion (SCG) and parasympathetic vasomotor fibers of intrinsic ganglion cells in the CB. The presence of nitric oxide (NO), a putative gaseous neurotransmitter substance in a number of neuronal and non-neuronal structures, was examined in the CB, PG and SCG of the rat using nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-d) histochemistry, nitric oxide synthase (NOS) immunohistochemistry and retrograde tracing. One week after injecting the retrograde tracer Fast Blue (FB) in the CB, we found that a subset of perikarya in the caudal portions of the PG and SCG were FB-labeled. Histochemistry and immunohistochemistry revealed that the majority of large- and medium-sized PG and SCG cells were NADPH-d positive and displayed a strong NOS immunostaining. We also observed that many varicose nerve fibers penetrating the CB and enveloping the glomus cells and blood vessels were NADPH-d reactive and expressed the constitutive isoforms of NOS, nNOS and eNOS. In addition, some autonomic microganglion cells embedded within, or located at the periphery of the CB, and not glomus or sustentacular cells were nNOS-immunopositive while CB microvasculature expressed eNOS. The present results suggest that NO is a transmitter in the autonomic nerve endings supplying the CB and is involved in efferent chemoreceptor inhibition by a dual mechanism. PMID- 27692877 TI - Impact of endocrine disrupting chemicals on onset and development of female reproductive disorders and hormone-related cancer. AB - A growing body of evidence suggests that exposure to chemical substances designated as endocrine disrupting chemicals (EDCs) due to their ability to disturb endocrine (hormonal) activity in humans and animals, may contribute to problems with fertility, pregnancy, and other aspects of reproduction. The presence of EDCs has already been associated with reproductive malfunction in wildlife species, but it remains difficult to prove causal relationships between the presence of EDCs and specific reproductive problems in vivo, especially in females. On the other hand, the increasing number of experiments with laboratory animals and in vitro research indicate the ability of different EDCs to influence the normal function of female reproductive system, and even their association with cancer development or progression. Research shows that EDCs may pose the greatest risk during prenatal and early postnatal development when organ and neural systems are forming. In this review article, we aim to point out a possible contribution of EDCs to the onset and development of female reproductive disorders and endocrine-related cancers with regard to the period of exposure to EDCs and affected endpoints (organs or processes). PMID- 27692878 TI - Hybrid robotic systems for upper limb rehabilitation after stroke: A review. AB - In recent years the combined use of functional electrical stimulation (FES) and robotic devices, called hybrid robotic rehabilitation systems, has emerged as a promising approach for rehabilitation of lower and upper limb motor functions. This paper presents a review of the state of the art of current hybrid robotic solutions for upper limb rehabilitation after stroke. For this aim, studies have been selected through a search using web databases: IEEE-Xplore, Scopus and PubMed. A total of 10 different hybrid robotic systems were identified, and they are presented in this paper. Selected systems are critically compared considering their technological components and aspects that form part of the hybrid robotic solution, the proposed control strategies that have been implemented, as well as the current technological challenges in this topic. Additionally, we will present and discuss the corresponding evidences on the effectiveness of these hybrid robotic therapies. The review also discusses the future trends in this field. PMID- 27692879 TI - Drug Repurposing: New Treatments for Zika Virus Infection? AB - To date, no antiviral agents have been approved for treating Zika virus (ZIKV) infection. Two recent drug-repurposing studies published in Cell Host & Microbe and Nature Medicine demonstrated that screening FDA-approved drugs for antiviral activity is a promising strategy for identifying therapeutics with novel activity against ZIKV infection. PMID- 27692881 TI - Decreased vaccine antibody titers following exposure to multiple metals and metalloids in e-waste-exposed preschool children. AB - We explored acquired immunity resulting from vaccination in 3 to 7-year-old children, chronically exposed to multiple heavy metals and metalloids, in an e waste recycling area (Guiyu, China). Child blood levels of ten heavy metals and metalloids, including lead (Pb), arsenic (As), mercury (Hg), chromium (Cr), cadmium (Cd), manganese (Mn), nickel (Ni), copper (Cu), zinc (Zn) and selenium (Se), and seven vaccine antibodies (diphtheria, pertussis, tetanus, hepatitis B, Japanese encephalitis, polio, measles) were measured. The exposed group had higher levels of blood Pb, Mn, Cu, Zn and Cr compared to the reference group (P < 0.05). Levels of all vaccine antibodies in the exposed group were significantly lower than in the reference group (P < 0.01). All vaccine antibodies negatively correlated with blood concentrations of Cu, Zn and Pb, based on spearman rank correlation analysis. Multiple logistic regression and univariate analyses identified the location of residence (Guiyu), high blood Pb (>10 MUg/dL) and high blood Cu and Zn (upper median value of each group) to be inversely associated with seven antibody titers. Antibody titers increased with age, BMI, high blood Mn (>15 MUg/L), and high blood Cd and Ni (upper median value of each group). Results suggest multiple heavy metal and metalloid exposure, especially to Pb, Zn and Cu, may be a risk factor inhibiting the development of child immunity, resulting in decreased child antibody levels against vaccines. PMID- 27692880 TI - Urinary Tract Infection: Pathogenesis and Outlook. AB - The clinical syndromes comprising urinary tract infection (UTI) continue to exert significant impact on millions of patients worldwide, most of whom are otherwise healthy women. Antibiotic therapy for acute cystitis does not prevent recurrences, which plague up to one fourth of women after an initial UTI. Rising antimicrobial resistance among uropathogenic bacteria further complicates therapeutic decisions, necessitating new approaches based on fundamental biological investigation. In this review, we highlight contemporary advances in the field of UTI pathogenesis and how these might inform both our clinical perspective and future scientific priorities. PMID- 27692882 TI - Updated national emission of perfluoroalkyl substances (PFASs) from wastewater treatment plants in South Korea. AB - A nationwide emission estimate of perfluoroalkyl substances (PFASs) from wastewater treatment plants (WWTPs) is required to understand the source-receptor relationship of PFASs and to manage major types of WWTPs. In this study, the concentrations of 13 PFASs (8 perfluorocarboxylic acids, 3 perfluoroalkane sulfonates, and 2 intermediates) in wastewater and sludge from 81 WWTPs in South Korea were collected. The emission pathways of PFASs were redefined, and then the national emission of PFASs from WWTPs was rigorously updated. In addition to the direct calculations, Monte Carlo simulations were also used to calculate the likely range of PFAS emissions. The total (Sigma13PFAS) emission (wastewater + sludge) calculated from the direct calculation with mean concentrations was 4.03 ton/y. The emissions of perfluorooctanoic acid (PFOA, 1.19 ton/y) and perfluorooctane sulfonate (PFOS, 1.01 ton/y) were dominant. The Monte Carlo simulations suggested that the realistic national emission of Sigma13PFASs is between 2 ton/y and 20 ton/y. Combined WWTPs treating municipal wastewater from residential and commercial areas were identified as a major emission source, contributing 65% to the total PFAS emissions. The Han and Nakdong Rivers were the primary contaminated rivers, receiving 89% of the total PFAS discharge from WWTPs. The results and methodologies in this study can be useful to establish a management policy for PFASs. PMID- 27692883 TI - Arthropod communities in a selenium-contaminated habitat with a focus on ant species. AB - The selenium contamination event that occurred at Kesterson Reservoir (Merced Co., CA) during the 1970-80s is a frequently cited example for the negative effects of contamination on wildlife. Despite the importance of arthropods for ecosystem services and functioning, relatively little information is available as to the impacts of pollution on arthropod community dynamics. We conducted surveys of the arthropod community present at Kesterson Reservoir to assess the impacts of selenium contamination on arthropod diversity, with a focus on ant species richness, composition and density. Trophic groups were compared to determine which arthropods were potentially receiving the greatest selenium exposure. Plant samples were analyzed to determine the selenium content by site and by location within plant. Soil concentrations varied across the study sites, but not across habitat types. Topsoil contained higher levels of selenium compared to core samples. Plants contained similar concentrations of selenium in their leaves, stems and flowers, but flowers contained the greatest range of concentrations. Individuals within the detritivores/decomposers and predators accumulated the greatest concentrations of selenium, whereas nectarivores contained the lowest concentrations. Species composition differed across the sites: Dorymyrmex bicolor was located only at the site containing the greatest soil selenium concentration, but Solenopsis xyloni was found at most sites and was predominant at six of the sites. Selenium concentrations in ants varied by species and collection sites. Nest density was also found to differ across sites, but was not related to soil selenium or any of the habitat variables measured in our study. Selenium was not found to impact species richness, but was a significant variable for the occurrence of two out of the eight native species identified. PMID- 27692884 TI - Assessment of the aryl hydrocarbon receptor-mediated activities of polycyclic aromatic hydrocarbons in a human cell-based reporter gene assay. AB - Activation of the aryl hydrocarbon receptor (AhR)-mediated activity is one of key events in toxicity of polycyclic aromatic hydrocarbons (PAHs). Although various classes of AhR ligands may differentially activate human and rodent AhR, there is presently a lack of data on the human AhR-inducing relative potencies (REPs) of PAHs. Here, we focused on estimation of the AhR-mediated activities of a large set of environmental PAHs in human gene reporter AZ-AhR cell line, with an aim to develop the human AhR-based REP values with potential implications for risk assessment of PAHs. The previously identified weakly active PAHs mostly failed to activate the AhR in human cells. The order for REPs of individual PAHs in human cells largely corresponded with the available data from rodent-based experimental systems; nevertheless, we identified differences up to one order of magnitude in REP values of PAHs between human and rodent cells. Higher REP values were found in human cells for some important environmental contaminants or suspected carcinogens, such as indeno[1,2,3-cd]pyrene, benz[a]anthracene or benzo[b]fluoranthene, while lower REP values were determined for methyl substituted PAHs. Our results also indicate that a different rate of metabolism for individual PAHs in human vs. rodent cells may affect estimation of REP values in human cell-based assay, and potentially alter toxicity of some compounds, such as benzofluoranthenes, in humans. We applied the AZ-AhR assay to evaluation of the AhR-mediated activity of complex mixtures of organic compounds associated with diesel exhaust particles, and we identified the polar compounds present in these mixtures as being particularly highly active in human cells, as compared with rodent cells. The present data suggest that differences may exist between the AhR-mediated potencies of PAHs in human and rodent cells, and that the AhR mediated effects of polar PAH derivatives and metabolites in human cell models deserve further attention. PMID- 27692885 TI - Air pollution and asthma attacks in children: A case-crossover analysis in the city of Chongqing, China. AB - Data on particulate matter of diameter <2.5 MUm (PM2.5) in the city of Chongqing were first announced in 2013. We wished to assess the effects of pollutants on asthmatic children in Chongqing, China. Daily numbers of hospital visits because of asthma attacks in children aged 0-18 years in 2013 were collected from the Children's Hospital of Chongqing Medical University. Data on pollutants were accessed from the nine air quality-monitoring stations in Chongqing. A time stratified case-crossover design was applied and conditional logistic regression was undertaken to analyze the data. We found that short-term exposure to PM10, PM2.5, sodium dioxide, nitrogen and carbon monoxide could trigger hospital visits for asthma in children. Nitrogen dioxide had an important role, whereas ozone had no effect. PMID- 27692887 TI - Novel use of field-portable-XRF for the direct analysis of trace elements in marine macroalgae. AB - Samples of dried marine macroalgae (Fucus serratus, Palmaria palmata and Ulva lactuca) have been analysed for trace elements by a novel, non-destructive approach involving a Niton field-portable-X-ray fluorescence (FP-XRF) spectrometer configured in a low density plastics mode with thickness correction. Detection limits for a 200-s counting time ranged from <5 MUg g-1 for As and Pb in F. serratus and As in P. palmata to several tens of MUg g-1 for Cd, Sb and Sn in all species tested. Arsenic, Cu, Pb and Zn were detected by the XRF in samples collected from a protected beach (n = 18) and in samples therefrom that had been exposed to additional aqueous elements in combination (n = 72) with concentrations returned (in MUg g-1) ranging from 3.9 to 39.7 for As, 13.0 to 307 for Cu, 6.1 to 14.7 for Pb and 12.5 to 522 for Zn. Independent measurements of trace elements in the macroalgae by ICP-MS following nitric acid digestion revealed a direct and significant proportionality with concentrations returned by the XRF, with slopes of the XRF-ICP relationships (As = 1.0; Cu = 2.3; Pb = 2.4; Zn = 1.7) that can be used to calibrate the instrument for direct measurements. The approach shows potential for the in situ monitoring of macroalgae in coastal regions that is currently being investigated. PMID- 27692886 TI - Uptake and subcellular distribution of triclosan in typical hydrophytes under hydroponic conditions. AB - The increasing discharge of pharmaceuticals and personal care products (PPCPs) into the environment has generated serious public concern. The recent awareness of the environmental impact of this emerging class of pollutants and their potential adverse effects on human health have been documented in many reports. However, information regarding uptake and intracellular distribution of PPCPs in hydrophytes under hydroponic conditions, and potential human exposure is very limited. A laboratory experiment was conducted using 14C-labeled triclosan (TCS) to investigate uptake and distribution of TCS in six aquatic plants (water spinach, purple perilla, cress, penny grass, cane shoot, and rice), and the subcellular distribution of 14C-TCS was determined in these plants. The results showed that the uptake and removal rate of TCS from nutrient solution by hydrophytes followed the order of cress (96%) > water spinach (94%) > penny grass (87%) > cane shoot (84%) > purple perilla (78%) > rice (63%) at the end of incubation period (192 h). The range of 14C-TCS content in the roots was 94.3% 99.0% of the added 14C-TCS, and the concentrations in roots were 2-3 orders of magnitude greater than those in shoots. Furthermore, the subcellular fraction concentration factor (3.6 * 102-2.6 * 103 mL g-1), concentration (0.58-4.47 MUg g 1), and percentage (30%-61%) of 14C-TCS in organelles were found predominantly greater than those in cell walls and/or cytoplasm. These results indicate that for these plants, the roots are the primary storage for TCS, and within plant cells organelles are the major domains for TCS accumulation. These findings provide a better understanding of translocation and accumulation of TCS in aquatic plants at the cellular level, which is valuable for environmental and human health assessments of TCS. PMID- 27692889 TI - Effects of slurry properties on simultaneous removal of SO2 and NO by ammonia Fe(II)EDTA absorption in sintering plants. AB - Simultaneous removal of SO2 and NO by ammonia-Fe(II)EDTA absorption has become a research focus in recent years. In order to get useful data for further industrialization, in this work the practical operating conditions of the sintering plant were simulated in a pilot-scale reactor in order to explore the effects of slurry properties on simultaneous removal of SO2 and NO. It was not conducive to the absorption of NO when (NH4)2SO4 concentration and slurry temperature had been increased. The initial NO removal efficiency decreased from 90.63% to 44.12% as the (NH4)2SO4 concentration increased from zero to 3.5 mol/L. With the increasing of Fe(II)EDTA concentration, SO32- concentration and pH value of absorption liquid and the absorption capacity of NO by Fe(II)EDTA solution increased. Especially the existence of SO32- ions in slurry had significantly improved the service life of chelating agents. The NO removal efficiency only decreased by 16.46% with the SO32- concentration of 0.3 mol/L after 30-min of operation. The chloride ions had no effects on the absorption of SO2 and NO. The results indicated that changes of slurry properties had different effects on simultaneous removal of SO2 and NO by ammonia-Fe(II)EDTA solution. The basic data offered by the experiments could effectively contribute to further industrial applications. PMID- 27692888 TI - Effective degradation of methylisothiazolone biocide using ozone: Kinetics, mechanisms, and decreases in toxicity. AB - Methylisothiazolone (MIT) is a common biocide that is widely used in water desalination reverse-osmosis processes. The transformation of MIT during water treatment processes is poorly understood. The kinetics and mechanisms involved in the degradation of MIT during ozonation were investigated in this study. Ozonation was found to be a useful way of degrading MIT in water, and the degradation rate constant was 0.11 (+/-0.1) * 103 L/(mol.s). The degradation rate constant did not change when the pH was increased from 3 to 9. The pre exponential factor A and the activation energy Ea for the ozonation process were 7.564 * 1013 L/(mol.s) and 66.74 kJ/mol, respectively. The decrease in the MIT concentration and the amount of ozone consumed were measured, and the stoichiometric factor alpha for the ozone consumption to MIT removal ratio was found to be 1.8. Several ozonation products were detected using time-of-flight mass spectrometry. Almost 32% of the organic sulfur in the MIT was oxidized to release sulfate ions, which caused a decrease in pH. Sulfur atoms were oxidized to sulfone species and then hydrolyzed to give sulfate during ozonation. Addition reactions involving carbon-carbon double bonds and the oxidation of alpha-carbon atoms also occurred. MIT was found to be lethal to Daphnia magna Straus (D. magna) with a median lethal concentration of 18.2 MUmol/L. Even though the primary ozonation products of MIT still showed some toxicity to D. magna, ozone could minimize the toxic effect after a long reaction time. PMID- 27692890 TI - Mainstreaming conservation agriculture in Malawi: Knowledge gaps and institutional barriers. AB - Conservation agriculture (CA) practices of reduced soil tillage, permanent organic soil coverage and intercropping/crop rotation, are being advocated globally, based on perceived benefits for crop yields, soil carbon storage, weed suppression, reduced soil erosion and improved soil water retention. However, some have questioned their efficacy due to uncertainty around the performance and trade-offs associated with CA practices, and their compatibility with the diverse livelihood strategies and varied agro-ecological conditions across African smallholder systems. This paper assesses the role of key institutions in Malawi in shaping pathways towards more sustainable land management based on CA by outlining their impact on national policy-making and the design and implementation of agricultural development projects. It draws on interviews at national, district and project levels and a multi-stakeholder workshop that mapped the institutional landscape of decision-making for agricultural land management practices. Findings identify knowledge gaps and institutional barriers that influence land management decision-making and constrain CA uptake. We use our findings to set out an integrated roadmap of research needs and policy options aimed at supporting CA as a route to enhanced sustainable land management in Malawi. Findings offer lessons that can inform design, planning and implementation of CA projects, and identify the multi-level institutional support structures required for mainstreaming sustainable land management in sub-Saharan Africa.

AB - This paper proposes a taxonomy of themes and a research agenda on sustainable infrastructure, with a focus on sustainable buildings (SB) and green infrastructure (GI). The citation databases of Web of Science formed the basis for a novel strategic thematic analysis of co-citation and co-occurrence of keywords with a longitudinal identification of themes during the last two decades (from 1995 to 2015) of an emerging and ever growing research area. SI is a multidisciplinary endeavour, including a diversified array of disciplines as general engineering, environmental ecology, construction, architecture, urban planning, and geography. This paper traces that the number of publications in SI is growing exponentially since 2003. Over 80% of total citations are concentrated in less than 10% of papers spread over a large number of journals. Most publications originate from the United States, Europe, Australia, and Asia. The main research streams in SI are green infrastructure, sustainable buildings, and assessment methods. Emerging and prevailing research themes include methodological issues of cost-effectiveness, project management and assessment tools. Substantive issues complement the research agenda of emerging themes in the areas of integration of human, economic and corporate social responsibility values in environmental sustainability, urban landscape and sustainable drainage systems, interdisciplinary research in green material, integrated policy research in urbanization, agriculture and nature conservation, and extensions of Green Building (GB) and GI to cities of developing countries. PMID- 27692892 TI - The role of nature-based infrastructure (NBI) in coastal resiliency planning: A literature review. AB - The use of nature-based infrastructure (NBI) has attracted increasing attention in the context of protection against coastal flooding. This review is focused on NBI approaches to improve coastal resilience in the face of extreme storm events, including hurricanes. We not only consider the role of NBI as a measure to protect people and property but also in the context of other ecological goods and services provided by tidal wetlands including production of fish and shellfish. Although the results of many studies suggest that populated areas protected by coastal marshes were less likely to experience damage when exposed to the full force of storm surge, it was absolutely critical to place the role of coastal wetlands into perspective by noting that while tidal marshes can reduce wave energy from low-to-moderate-energy storms, their capacity to substantially reduce storm surge remains poorly quantified. Moreover, although tidal marshes can reduce storm surge from fast moving storms, very large expanses of habitat are needed to be most effective, and for most urban settings, there is insufficient space to rely on nature-based risk reduction strategies alone. The success of a given NBI method is also context dependent on local conditions, with potentially confounding influences from substrate characteristics, topography, near shore bathymetry, distance from the shore and other physical factors and human drivers such as development patterns. Furthermore, it is important to better understand the strengths and weaknesses of newly developed NBI projects through rigorous evaluations and characterize the local specificities of the particular built and natural environments surrounding these coastal areas. In order for the relevant science to better inform policy, and assist in land-use challenges, scientists must clearly state the likelihood of success in a particular circumstance and set of conditions. We conclude that "caution is advised" before selecting a particular NBI method as there is no "one size fits all" solution to address site specific conditions. PMID- 27692893 TI - Benefits transfer and the aquatic environment: An investigation into the context of fish passage improvement. AB - We present findings from a choice experiment investigating improvements in the aquatic environment from mitigation of barriers to fish passage. Implemented at a local and national level, results reveal positive preferences for increased numbers of fish species as well as fish abundance. In addition, we examine if in this case the willingness to pay estimates are suitable for direct transfer between national and local settings. For both samples, we consider the extent to which stated attribute non-attendance impacts estimates of willingness to pay and the potential ability of researchers to transfer values between contexts. Implications of the use of benefit transfer within this policy context are discussed in light of our findings. PMID- 27692895 TI - An evaluation of forums for discussions on inclusion in a college of nursing. AB - BACKGROUND: The lack of diversity in the nursing profession could be an outcome of unconscious biases. Forums allowing the personal reflection and discourse of these unconscious biases are needed in order for a diverse and inclusive learning environment to exist. PURPOSE: The purpose of this study was to describe the experiences of students, staff, faculty members, and guests participating in a forum on diversity and inclusion. METHODS: An exploratory design was used to understand the experiences of college of nursing students, staff, faculty members, and guests who participated in a diversity and inclusion intervention sponsored by the college of nursing's Diversity Advisory Council. Attendees to 12 diversity book club, movie night, and speaker series' sessions completed a program evaluation tool. Responses to open-ended items were analyzed using a constant comparative analysis method.Responses from 197 participants were analyzed. Eight book club, seven movie night, and six speaker series' themes were derived from the data including Humanness is Universal, Personal Connection, The Problem, Awareness of Disparity, Make a Difference, and No Change. DISCUSSION: Participants at each session critically dialogued about their conscious and unconscious biases. The study findings show that participants also were able to document changes to their knowledge, attitudes, and behaviors in relation to the historically oppressed populations focused on during the intervention activities. CONCLUSION: Education entertainment as used in this study was a valuable mechanism for hosting conversations about diversity and inclusion. PMID- 27692894 TI - mRNA expression profiles of colorectal liver metastases as a novel biomarker for early recurrence after partial hepatectomy. AB - BACKGROUND: Identification of specific risk groups for recurrence after surgery for isolated colorectal liver metastases (CRLM) remains challenging due to the heterogeneity of the disease. Classical clinicopathologic parameters have limited prognostic value. The aim of this study was to identify a gene expression signature measured in CRLM discriminating early from late recurrence after partial hepatectomy. METHODS: CRLM from two patient groups were collected: I) with recurrent disease <=12 months after surgery (N = 33), and II) without recurrences and disease free for >=36 months (N = 30). The patients were clinically homogeneous; all had a low clinical risk score (0-2) and did not receive (neo-) adjuvant chemotherapy. Total RNA was hybridised to Illumina arrays, and processed for analysis. A leave-one-out cross validation (LOOCV) analysis was performed to identify a prognostic gene expression signature. RESULTS: LOOCV yielded an 11-gene profile with prognostic value in relation to recurrent disease <=12 months after partial hepatectomy. This signature had a sensitivity of 81.8%, with a specificity of 66.7% for predicting recurrences (<=12 months) versus no recurrences for at least 36 months after surgery (X2 P < 0.0001). CONCLUSION: The current study yielded an 11-gene signature at mRNA level in CRLM discriminating early from late or no relapse after partial hepatectomy.

AB - Heterogeneities and oncogenesis essentially result from proteomic disorders orchestrated by changes in DNA and/or cytoplasmic mRNA. These genetic fluctuations, however, cannot be decoded through conventional label-free methods (e.g., patch clamps, electrochemical cellular biosensors, etc.) or morphological characterization. Molecular beacons (MBs) have recently emerged as efficient probes for interrogating biomarkers in live cancer cells. MBs hybridize with their intracellular targets (e.g., mRNAs, DNAs, or proteins), emitting a fluorescent signal that can be quantified and correlated with the expression levels of their targets. In this review we discuss MB probes with different delivery platforms for intracellular probing as well as novel MB designs for detecting a variety of targets in living cancer cells. Finally, we describe current trends in MB-based intracellular biosensors. PMID- 27692898 TI - Peri-implant bone loss around platform-switched Morse taper connection implants: a prospective 60-month follow-up study. AB - The aim of this study was to measure the crestal bone level changes at 60 months of follow-up and to evaluate the influence of biologically relevant, anatomical, and implant-related variables. A prospective study design was used. STROBE guidelines were followed. A total of 576 implants were inserted in 270 patients needing an implant-supported, partial, fixed dental prosthesis or a single crown. Standardized peri-apical radiographs were obtained at 2 months (time of implant abutment connection and prosthetic loading) and 60 months of follow-up. Descriptive statistics were used and inter- and intra-examiner reliability determined. A mixed model was used to evaluate the predictor variables. The correlation among multiple implants inserted in a single patient was considered. Significance was assessed using the type 3 test. Sensitivity analyses, least squares means analyses, t-tests, and chi2 tests were also conducted. The statistical analysis was performed at the implant level; P<0.05 indicated statistical significance. At the 60-month follow-up, the mean marginal bone remodelling was -0.59+/-1.34mm (range -5.70 to 3.65mm). Marginal bone loss was significantly influenced by implant depth, implant location, and the interactions implant depth*jaw, implant location*timing of implant placement, and jaw*implant diameter. At the 60-month follow-up, a low mean marginal bone loss was found, which was significantly higher with subcrestal implants and anterior implants. PMID- 27692897 TI - Optogenetic Immunomodulation: Shedding Light on Antitumor Immunity. AB - Microbial opsin-based optogenetic tools have been transformative for neuroscience. To extend optogenetic approaches to the immune system to remotely control immune responses with superior spatiotemporal precision, pioneering tools have recently been crafted to modulate lymphocyte trafficking, inflammasome activation, dendritic cell (DC) maturation, and antitumor immunity through the photoactivation of engineered chemokine receptors and calcium release-activated calcium channels. We highlight herein some conceptual design strategies for installing light sensitivities into the immune signaling network and, in parallel, we propose potential solutions for in vivo optogenetic applications in living organisms with near-infrared light-responsive upconversion nanomaterials. Moreover, to move beyond proof-of-concept into translational applications, we discuss future prospects for integrating personalized immunoengineering with optogenetics to overcome critical hurdles in cancer immunotherapy.

AB - OBJECTIVES: The olfactory nerve is anatomically susceptible to injury from pollution in inspired air, but there are no large-scale epidemiologic studies investigating this relationship. METHODS: Cross-sectional study using data from the National Social Life, Health, and Aging Project, a representative sample of home-dwelling US adults age 57-85 years. Olfactory function was tested using a validated 5-item odor identification test (Sniffin' Sticks). Exposure to fine particulate matter (PM2.5) at each respondent's home was estimated as 1-12 month moving averages prior to olfactory assessment using validated spatio-temporal models. RESULTS: Olfactory dysfunction was significantly associated with PM2.5 exposures averaged over 3-12 months in urban-dwelling respondents. The strongest effect was for 6 month average exposure (per 1-IQR increase in PM2.5: OR 1.28, 95% CI 1.05, 1.55) adjusting for age, gender, race/ethnicity, education, cognition, comorbidity, smoking, and the season. Interestingly, the most deleterious effects were observed among the youngest respondents, 57-64 years old, and those living in the northeast and south. CONCLUSIONS: We show for the first time that air pollution exposure is associated with poor olfaction among urban-living, older US adults. PMID- 27692903 TI - Intubated Versus Nonintubated General Anesthesia for Video-Assisted Thoracoscopic Surgery-A Case-Control Study. AB - OBJECTIVE: General anesthesia with endobronchial intubation and one-lung positive pressure ventilation always has been considered mandatory for thoracic surgery. Recently, there has been interest in nonintubated techniques for video-assisted thoracoscopic surgery (VATS) in awake and sedated patients. The authors' center developed a nonintubated technique with spontaneous ventilation with the patient under general anesthesia using a supraglottic airway device. The authors believe that this was the first study to compare a nonintubated general anesthetic technique with an intubated general anesthetic technique for VATS. DESIGN: Retrospective, observational study. SETTING: Specialist cardiothoracic hospital in the United Kingdom. PARTICIPANTS: All patients who underwent elective minor VATS over 8 months (n = 73). INTERVENTIONS: A nonintubated general anesthetic technique with spontaneous ventilation via a supraglottic airway device was used for minor VATS procedures. This was compared with a case-matched intubated group. MEASUREMENTS AND MAIN RESULTS: Both groups had comparable baseline characteristics and surgical procedures. The anesthetic time was shorter in the nonintubated group (13.6+/-8.3 v 24.1+/-10.9 minutes, p<0.001). Surgical operating time and feasibility were similar. Intraoperatively, there were increases in end-tidal carbon dioxide (59.1+/-12.9 v 41.8+/-4.6, p<0.001) and respiratory rate (17.8+/-5.6 v 13.5+/-2.0, p<0.001) in the nonintubated group. Fewer patients in the nonintubated group had moderate-severe pain during recovery (19.4% v 48.4%, p = 0.02) and pain on discharge to the ward (25.8% v 61.3%, p = 0.004). There was a trend toward shorter recovery times, reduced oxygen requirement, and shorter hospital stays in the nonintubated group. CONCLUSIONS: A nonintubated general anesthetic technique is a feasible alternative to intubated general anesthesia for minor VATS procedures.

PMID- 27692902 TI - DNM3 and genetic modifiers of age of onset in LRRK2 Gly2019Ser parkinsonism: a genome-wide linkage and association study. AB - BACKGROUND: Leucine-rich repeat kinase 2 (LRRK2) mutation 6055G->A (Gly2019Ser) accounts for roughly 1% of patients with Parkinson's disease in white populations, 13-30% in Ashkenazi Jewish populations, and 30-40% in North African Arab-Berber populations, although age of onset is variable. Some carriers have early-onset parkinsonism, whereas others remain asymptomatic despite advanced age. We aimed to use a genome-wide approach to identify genetic variability that directly affects LRRK2 Gly2019Ser penetrance. METHODS: Between 2006 and 2012, we recruited Arab-Berber patients with Parkinson's disease and their family members (aged 18 years or older) at the Mongi Ben Hamida National Institute of Neurology (Tunis, Tunisia). Patients with Parkinson's disease were diagnosed by movement disorder specialists in accordance with the UK Parkinson's Disease Society Brain Bank criteria, without exclusion of familial parkinsonism. LRRK2 carrier status was confirmed by Sanger sequencing or TaqMan SNP assays-on-demand. We did genome wide linkage analysis using data from multi-incident Arab-Berber families with Parkinson's disease and LRRK2 Gly2019Ser (with both affected and unaffected family members). We assessed Parkinson's disease age of onset both as a categorical variable (dichotomised by median onset) and as a quantitative trait. We used data from another cohort of unrelated Tunisian LRRK2 Gly2019Ser carriers for subsequent locus-specific genotyping and association analyses. Whole-genome sequencing in a subset of 14 unrelated Arab-Berber individuals who were LRRK2 Gly2019Ser carriers (seven with early-onset disease and seven elderly unaffected individuals) subsequently informed imputation and haplotype analyses. We replicated the findings in separate series of LRRK2 Gly2019Ser carriers originating from Algeria, France, Norway, and North America. We also investigated associations between genotype, gene, and protein expression in human striatal tissues and murine LRRK2 Gly2019Ser cortical neurons. FINDINGS: Using data from 41 multi-incident Arab-Berber families with Parkinson's disease and LRRK2 Gly2019Ser (150 patients and 103 unaffected family members), we identified significant linkage on chromosome 1q23.3 to 1q24.3 (non-parametric logarithm of odds score 2.9, model-based logarithm of odds score 4.99, theta=0 at D1S2768). In a cohort of unrelated Arab-Berber LRRK2 Gly2019Ser carriers, subsequent association mapping within the linkage region suggested genetic variability within DNM3 as an age-of-onset modifier of disease (n=232; rs2421947; haplotype p=1.07 * 10-7). We found that DNM3 rs2421947 was a haplotype tag for which the median onset of LRRK2 parkinsonism in GG carriers was 12.5 years younger than that of CC carriers (Arab-Berber cohort, hazard ratio [HR] 1.89, 95% CI 1.20 2.98). Replication analyses in separate series from Algeria, France, Norway, and North America (n=263) supported this finding (meta-analysis HR 1.61, 95% CI 1.15 2.27, p=0.02). In human striatum, DNM3 expression varied as a function of rs2421947 genotype, and dynamin-3 localisation was perturbed in murine LRRK2 Gly2019Ser cortical neurons. INTERPRETATION: Genetic variability in DNM3 modifies age of onset for LRRK2 Gly2019Ser parkinsonism and informs disease-relevant translational neuroscience. Our results could be useful in genetic counselling for carriers of this mutation and in clinical trial design.

PMID- 27692906 TI - Ghrelin, leptin, and glycemic control after sleeve gastrectomy versus Roux-en-Y gastric bypass-results of a randomized clinical trial. AB - BACKGROUND: Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) cause weight loss and metabolic improvement, but results of published studies are contradictory. OBJECTIVES: The aim of this study was to compare the effects of SG and RYGB on ghrelin, leptin, and glucose homeostasis in a randomized controlled trial. SETTING: University hospital, Poland. METHODS: Seventy-two morbidly obese patients were randomly selected to undergo either SG (n = 36) or RYGB (n = 36). Fasting ghrelin, leptin, glucose, insulin, C-peptide, glucagon, glycated hemoglobin, and homeostasis model assessment of insulin resistance were assessed preoperatively and at 1, 6, and 12 months postoperatively. No differences were found in anthropometric and biochemical parameters between the study groups at baseline. RESULTS: Sixty-nine (95.8%) patients completed the study. Percentage of excess weight loss at 12 months was 67.6+/-19.3% after SG and 64.2+/-18.5% after RYGB (P>.05). Fasting ghrelin levels decreased 1 month after SG (from 76.8 pmol/L to 35.3 pmol/L; P<.05) and remained reduced until 12 months (41.6 pmol/L; P<.05) but increased 12 months after RYGB from 74.6 pmol/L to 130.2 pmol/L (P<.05). Leptin, glucose, insulin, and C-peptide concentrations and glycated hemoglobin and homeostasis model assessment of insulin resistance values decreased significantly in both groups during 12 months. CONCLUSIONS: RYGB and SG induce comparable weight loss and improvement in metabolism of glucose. Ghrelin levels decrease after SG and increase after RYGB, but this difference does not affect similar outcomes of these procedures during 1-year follow-up. The contribution of ghrelin to weight loss or metabolic benefits after bariatric surgery is not straightforward, but rather influenced by multiple factors. PMID- 27692907 TI - Changes in self-reported eating patterns after laparoscopic sleeve gastrectomy: a pre-post analysis and comparison with conservatively treated patients with obesity. AB - BACKGROUND: Patients with severe obesity need to adapt to surgically induced changes in their eating behaviors to maintain treatment success. OBJECTIVES: This study examined the effects of laparoscopic sleeve gastrectomy (LSG) on weight loss and on 3 dimensions of eating behavior, namely, cognitive restraint, disinhibition, and hunger. Outcomes of the LSG group were compared with a group of conservatively treated (CT) patients, who underwent a 1-year multimodal weight reduction group program that included dietary advice, physical exercise, psychoeducation, cognitive-behavioral therapy, training in Jacobson's progressive muscle relaxation, and social group support. SETTING: The study setting was a multidisciplinary obesity center located in a university hospital. METHODS: A sample of 102 patients with obesity were investigated using the Three-Factor Eating Questionnaire before and, on average, 19 (+/-5) months after weight loss intervention. Of the 102 patients, 62 (age 45.8+/-10.8 years, 71% females) underwent LSG, and 40 patients (age 50.6+/-11.3 years, 77.5% females) underwent the CT program. Patients were assigned to either the surgical or the nonsurgical intervention group following clinical guidelines and patient preference. RESULTS: In the LSG group, total weight loss was 25.9+/-11.0%, excess weight loss was 52.8+/-24.1%, and body mass index decreased from 51.4+/-8.1 to 38.0+/-7.8 kg/m2. In the CT group, total weight loss was 5.4+/-10.6%, excess weight loss was 13.9+/ 27.1%, and body mass index decreased from 40.3+/-6.7 to 38.0+/-7.2 kg/m2. Significant improvements in self-reported eating behaviors were observed in both groups, that is, an increased cognitive restraint of eating, a decreased disinhibition of eating control, and a reduced degree of perceived hunger. In contrast, whereas Three-Factor Eating Questionnaire scores before weight loss intervention did not differ between groups, LSG patients reported significantly greater reductions in disinhibition and hunger than CT patients did after weight loss intervention. In both groups, greater weight loss was associated with decreased hunger sensations. CONCLUSION: In the second follow-up year, LSG was associated with greater weight loss and greater improvements in self-reported eating behaviors compared with conservative treatment.

AB - BACKGROUND: Rapid gastric emptying has been proposed to justify the increase in glucagon-like polypeptide-1 (GLP-1) after laparoscopic sleeve gastrectomy (LSG). OBJECTIVES: To assess gastric emptying changes after LSG and their relationship with GLP-1 secretion. SETTING: San Salvatore Hospital general surgery unit, University of L'Aquila, Italy. METHODS: 52 patients underwent gastric emptying scintigraphy for liquid and solid foods, before and 3 months after LSG. Twenty six patients were in the liquid group (L group) and the remaining in the solid group (S group). We evaluated the half time of gastric emptying (T1/2) and percentage of gastric retention (%GR) at 15, 30, and 60 minutes for liquids and at 30, 60, 90, and 120 minutes for solids. GLP-1 plasma concentrations were measured in each group before and after LSG and related to %GR. Statistical analysis was performed by Chi2 test and Pearson correlation(r). RESULTS: After surgery, T1/2 was significantly accelerated: 15.2+/-13 min and 33.5+/-18 min in the L group and S group, respectively (P<.05). In both groups, GLP-1 plasma concentrations were increased at each blood sampling time: 2.91+/-2.9 pg/mL, 3.06+/-3.1 pg/mL and 3.21+/-2.6 pg/mL at 15, 30, and 60 minutes, respectively, (P<.05) for L group and 2.72+/-1.5 pg/mL, 2.89+/-2.1 pg/mL, 2.93+/-1.8 pg/mL, and 2.95+/-1.9 pg/mL at 30, 60, 90, and 120 minutes, respectively, (P< .05) for the S group. After LSG, GLP-1 and %GR presented a negative linear correlation (r) at each blood sampling time in both groups. CONCLUSION: The rapid gastric emptying 3 months after LSG upregulates the production of GLP-1 in the distal bowel. Further studies are needed to confirm these findings.

PMID- 27692914 TI - Early reduction of resting energy expenditure and successful weight loss after Roux-en-Y gastric bypass. AB - BACKGROUND: Weight loss and body composition changes after Roux-en-Y gastric bypass (RYGB) may influence resting energy expenditure (REE). The effect of lower REE after the procedure on long-term weight remains to be elucidated. OBJECTIVE: To evaluate the effects of RYGB on REE and body composition 6 months after RYGB and to find out whether postsurgery REE affects weight at 12 and 18 months SETTING: Tertiary referral hospital, southern Brazil METHOD: A prospective study involving 30 RYGB patients aged>18 years was performed. Body composition was evaluated by X-ray absorptiometry and REE by indirect calorimetry. All patients were assessed before RYGB and 6 months postoperatively. Further analysis of weight was carried out at 12 and 18 months. RESULTS: Baseline body mass index was 49+/-9 kg/m2 and mean weight was 128+/-19 kg, half of which comprised fat mass (50+/-5%). Baseline mean REE was 2297+/-182 kcal/d. The percent total weight loss was 26+/-7%, 32+/-9%, and 34+/-9% at 6, 12, and 18 months, respectively. The percent excess weight loss gradually increased from 54 +/- 12% at 6 months, to 67 +/- 18% at 12 months, and 71 +/- 19% at 18 months. REE was significantly lower at follow-up (-405+/-108 kcal/d; P<.001). Furthermore, an inverse correlation between REE at 6 months and percent excess weight loss at 18 months (r =-.612; P = .035) was observed in the subgroup of patients whose REE decreased>405 kcal/d at 6 months. CONCLUSION: Patients undergoing RYGB who had a substantial drop in REE at 6 months may exhibit less long-term weight loss.

PMID- 27692918 TI - Optimal Timing for Elective Early Primary Repair of Tetralogy of Fallot: Analysis of Intermediate Term Outcomes. AB - BACKGROUND: We have previously demonstrated that early primary repair of tetralogy of Fallot with pulmonary stenosis (TOF) can be safely performed without increase in hospital resource utilization or compromise to surgical technical performance scores (TPS). We sought to identify the optimal timing for elective early primary repair of TOF with respect to intermediate-term reintervention. METHODS: Retrospective review of all patients with TOF undergoing elective primary repair between September 2004 and December 2013 was performed. Patients were stratified into reintervention group or no reintervention group. Multivariable Cox regression analysis identified independent predictors of reintervention. Youden's J-index in receiver operating characteristic analysis identified optimal age cutoff predictive of reintervention. Kaplan-Meier analysis with the log-rank test compared reintervention rates stratified by age and TPS. RESULTS: A total of 129 patients with median (interquartile range) age and weight of 78 days (56 to 111) and 5 kg (4.1 to 5.7), respectively, underwent primary repair. After a median (interquartile range) follow-up of 2.3 years (0.1 to 4.6), 18 patients (14%) required a total of 22 reinterventions. Youden's J-index revealed significantly lower risk of intermediate-term reintervention when repaired after 55 days of age (8% for >55 days old versus 31% for <=55 days of age). Multivariable Cox regression identified age 55 days and younger (hazard ratio [HR] 4.5, 95% confidence interval [CI] 1.6 to 12.8, p = 0.004), valve sparing repair (HR 15.3, 95% CI 1.8 to 128.5, p < 0.001), residual right ventricular outflow tract (RVOT) gradient (HR 1.11, 95% CI 1.1 to 1.2, p < 0.001), and inadequate TPS (HR 21.5, 95% CI 7.4 to 63, p < 0.001) as independent predictors of overall intermediate-term reintervention. CONCLUSIONS: Elective repair in patients greater than 55 days of age, irrespective of size of the patient, can be safely performed without any increase in reintervention rates. Both residual peak RVOT gradient and TPS are effective in identifying patients at increased risk of reintervention. PMID- 27692917 TI - Clinical Significance of Spontaneous Echo Contrast on Extracorporeal Membrane Oxygenation. AB - BACKGROUND: Spontaneous echo contrast (SEC) is known to be a predisposition to thromboembolism and cerebrovascular accident. The aim of this study was to investigate the risk factors and the consequences of SEC in patients who were placed on venoarterial extracorporeal membrane oxygenation (VA-ECMO) because of cardiogenic shock. METHODS: Between January 2011 and December 2014, 98 patients underwent the insertion of VA-ECMO because of cardiogenic shock in our institution. Transthoracic and transesophageal echocardiography was performed and interpreted by National Board of Echocardiography certified cardiologists. Patients were divided into 2 groups based on the presence or absence of SEC. Clinical data, echocardiographic measurements, and outcomes were compared between the 2 groups. RESULTS: Of the 98 patients, 22 patients (22%) had SEC on echocardiography. Patients in the SEC group had a lower ejection fraction (8.0% versus 29%; p < 0.001), a lower pulsatility index (defined by [systolic blood pressure - diastolic blood pressure]/mean blood pressure) while receiving ECMO (0.13 +/- 0.14 versus 0.26 +/- 0.22; p = 0.009). The SEC group had a higher rate of intracardiac thrombus (46% versus 13%; p = 0.002) and stroke (36% versus 7.9%; p = 0.002). On univariate analysis, intracardiac thrombus, SEC, and low pulsatility were significant risk factors for the development of stroke. On multivariate analysis, SEC was the only independent risk factor for stroke. CONCLUSIONS: SEC on VA-ECMO resulted in an increased risk of intracardiac thrombus and stroke. Maintaining pulsatility while the patient is on ECMO may result in a decreased chance of developing SEC and stroke. PMID- 27692919 TI - Correction to Lancet Diabetes Endocrinol 2016; 4: 812-14.

We evaluated the feasibility of hypofractionated dose-painting radiotherapy and the associated toxicity. The possibility to streamline a radiobiologically optimised planning protocol was also investigated. MATERIALS AND METHODS: Twenty-eight patients were treated using a dose-painting approach; boost volumes were identified with functional magnetic resonance imaging scans. The prostate dose outside the boost volume was 60 Gy in 20 fractions, and the maximum integrated boost dose was set to 68 Gy, provided that the dose constraints to the organs at risk could be fulfilled. Rotational intensity modulated radiotherapy was used with daily image guidance and fiducial markers. RESULTS: The boost dose was escalated to 68 Gy for 25 patients (median dose 69 Gy, range 68-70 Gy); for three patients the boost dose was 67 Gy, due to the proximity of the urethra and/or the rectum. The mean normal tissue complication probability for rectal bleeding was 4.7% (range 3.4-5.8%) and was 3.5% for faecal incontinence (range 2.3-5.0%). At a median follow-up of 38 months (range 32-45) there was no grade 3 toxicity. Two patients developed grade 2 genitourinary toxicity (7.1%) and none developed grade 2 gastrointestinal toxicity. The mean prostate-specific antigen (PSA) for 23 patients who had stopped the adjuvant hormone therapy with a normal testosterone was 0.27 ng/ml (0.02-0.72) at follow up; two patients have suppressed PSA and testosterone after stopping 3 year adjuvant hormone and three patients have relapsed (one pelvic node, two PSA only) at 36, 12 and 42 months, respectively. CONCLUSIONS: A hypofractionated radiotherapy schedule, 60 Gy in 20 fractions with intra-prostatic boost dose of 68 Gy, can be achieved without exceeding dose constraints for organs at risk. Hypofractionated dose-painting escalated radiotherapy has an acceptable safety profile. The same planning protocol was used in a phase II single-arm trial (BIOPROP20: ClinicalTrials.gov identifier NCT02125175) and will further be used in a large phase III randomised trial (PIVOTALboost): patients will be randomised standard radiotherapy (60 Gy in 20 fractions) with or without lymph node radiotherapy versus dose-painting radiotherapy with or without lymph node radiotherapy; the trial will be opened for recruitment in summer 2017.

AB - Sickle cell anaemia is rare in France but frequent in Africa, leading to rigid, sickle-like shape red blood cells which bind together blocking microcirculation under certain circumstances. The vaso-occlusive crisis is the most frequent clinical manifestation especially in case of homozygous disease. Sickle cells disease is therefore usually considerated as a contraindication to microsurgery, however sometimes, a free flap procedure is mandatory. We here report the case of a 47-year-old man suffering with homozygous sickle cell anaemia and needing an antebrachial free flap procedure for a tongue reconstruction. The postoperative course was unremarkable apart from a delayed healing which is common in this particular localization. A review of the litterature allows to list the precautions to be taken to ensure a microsurgical procedure with this medical background. The preoperative examination has to assess usual sickle cell disease comorbidities such as kidney failure, heart failure or pulmonary hypertension. All the events leading to either low output syndrome, hypoxia, hypothermia, or a stress caused by uncontrolled pain should be avoided per- and postoperatively. With an optimum medical care, microsurgery is possible even in patients suffering with sickle cells anaemia. This case is rare in France but will become frequent in Africa with the improvement of the healthcare system, allowing to give all patients the best medical care.

PMID- 27692924 TI - An overview on the organic pollution around the Qinghai-Tibet plateau: The thought-provoking situation. AB - The Qinghai-Tibet Plateau plays an important role in the ecological safety and human health of the surroundings due to its unique geographical position and function. Therefore, it is necessary to study the pollution status and potential risk in this area. This study summarizes the distribution of different organic pollutants in biota and environmental media of the Qinghai-Tibet Plateau. Moreover, it also pays attention to the potential health risks of these organic pollutants. Organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) were the most frequently detected in different matrices. In general, the carcinogenic risks of organic pollutants were ranked in the very-low to moderate range for both children and adults. The carcinogenic risks of organic pollutants in fish, food, and water for children were 1-2 times higher than those for adults, while risks of organic pollutants in soil/sediment and in air for children were generally 10.6-16.5 and 2.6-2.8 times higher than those for adults, respectively. The maximal hazard quotient for non-carcinogenic risk was 0.95 (potential risk for children posed by organic pollutants in yak milk of Ruoergai), almost reaching an unacceptable level. Therefore, the potential health risks could not be neglected, especially for children who were more likely to be affected by the pollutants. PMID- 27692926 TI - Differential health effects of short-term exposure to source-specific particles in London, U.K. AB - BACKGROUND: There is ample evidence of adverse associations between short-term exposure to ambient particle mass concentrations and health but little is known about the relative contribution from various sources. METHODS: We used air particle composition and number networks in London between 2011 and 2012 to derive six source-related factors for PM10 and four factors for size distributions of ultrafine particles (NSD). We assessed the associations of these factors, at pre-specified lags, with daily total, cardiovascular (CVD) and respiratory mortality and hospitalizations using Poisson regression. Relative risks and 95% confidence intervals (CI) were expressed as percentage change per interquartile range increment in source-factor mass or number concentration. We evaluated the sensitivity of associations to adjustment for multiple other factors and by season. RESULTS: We found no evidence of associations between PM10 or NSD source-related factors and daily mortality, as the direction of the estimates were variable with 95% CI spanning 0%. Traffic-related PM10 and NSD displayed consistent associations with CVD admissions aged 15-64years (1.01% (95%CI: 0.03%, 2.00%) and 1.04% (95%CI: -0.62%, 2.72%) respectively) as did particles from background urban sources (0.36% for PM10 and 0.81% for NSD). Most sources were positively associated with pediatric (0-14years) respiratory hospitalizations, with stronger evidence for fuel oil PM10 (3.43%, 95%CI: 1.26%, 5.65%). Our results did not suggest associations with cardiovascular admissions in 65+ or respiratory admissions in 15+ age groups. Effect estimates were generally robust to adjustment for other factors and by season. CONCLUSIONS: Our findings are broadly consistent with the growing evidence of the toxicity of traffic and combustion particles, particularly in relation to respiratory morbidity in children and cardiovascular morbidity in younger adults. PMID- 27692927 TI - Effects of Theta Burst Stimulation on Suprahyoid Motor Cortex Excitability in Healthy Subjects. AB - BACKGROUND: Continuous theta burst stimulation (cTBS) and intermittent TBS (iTBS) are powerful patterns of repetitive transcranial magnetic stimulation (rTMS), with substantial potential for motor function rehabilitation post-stroke. However, TBS of suprahyoid motor cortex excitability has not been investigated. This study investigated TBS effects on suprahyoid motor cortex excitability and its potential mechanisms in healthy subjects. METHODS: Thirty-five healthy subjects (23 females; mean age = 21.66 +/- 1.66 years) completed three TBS protocols on separate days, separated by at least one week. A stereotaxic neuronavigation system facilitated accurate TMS positioning. Left and right suprahyoid motor evoked potentials (SMEP) were recorded using single-pulse TMS from the contralateral suprahyoid motor cortex before stimulation (baseline) and 0, 15, and 30 min after stimulation. The SMEP latency and amplitude were analyzed via repeated measures analysis of variance. RESULTS: cTBS suppressed ipsilateral suprahyoid motor cortex excitability and activated the contralateral suprahyoid motor cortex. iTBS facilitated ipsilateral suprahyoid motor cortex excitability; however, it did not affect the contralateral excitability. iTBS eliminated the inhibitory effect caused by cTBS applied to the contralateral suprahyoid motor cortex. TBS had no significant effect on the latencies of bilateral SMEP. TBS effects on suprahyoid motor cortex excitability lasted a minimum of 30 min. CONCLUSIONS: TBS effectively regulates suprahyoid motor cortex excitability. Suppression of excitability in one hemisphere leads to further activation of the corresponding contralateral motor cortex. iTBS reverses the inhibitory effect induced by cTBS of the contralateral suprahyoid motor cortex. PMID- 27692925 TI - Behavioral difficulties in 7-year old children in relation to developmental exposure to perfluorinated alkyl substances. AB - BACKGROUND: Perfluorinated alkyl substances (PFAS) are suspected endocrine disruptors that are highly persistent and neurotoxic in animals. Human epidemiological studies of exposure-related deviations of children's behaviors are sparse. We assessed the associations between prenatal, 5- and 7-year PFAS exposures and behavioral problem scores in 7-year Faroese children. METHODS: Concentrations of perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA), perfluorooctane sulfonate (PFOS), and perfluorohexane sulfonic acid (PFHxS) were measured in maternal serum and in serum from children at ages 5 and 7years (n=539, 508, and 491, respectively). We used multivariable regressions and structural equations models to estimate the covariate-adjusted associations between serum-PFAS concentrations and behavioral difficulties, as assessed by the strengths and difficulties questionnaire (SDQ) at age 7. RESULTS: Serum-PFOS and PFHxS concentrations declined over time, whereas PFOA, PFNA, and PFDA tended to increase. No associations were observed between prenatal PFAS concentrations and SDQ scores. However, a two-fold increase in 5-year serum-PFOA, PFNA, and PFDA concentrations was associated with increases in total SDQ scores by 1.03 (95% CI: 0.11, 1.95), 0.72 (95% CI: 0.07, 1.38) and 0.78 points (95% CI: 0.01, 1.55), respectively. For SDQ subscales, significant associations were found in regard to hyperactivity, peer relationship, and conduct problems, as well as internalizing and externalizing problems and autism screening composite scores. Cross-sectional analyses at age 7years showed possible sex-dimorphic associations between PFAS concentrations and SDQ scores, where girls had consistently positive associations with SDQ scores whereas boys exhibited a pattern of negative or null associations. CONCLUSIONS: Higher serum PFAS concentrations at ages 5- and 7-years, but not prenatally, were associated with parent-reported behavioral problems at age 7.

AB - BACKGROUND: Responses to plasticity-inducing brain stimulation protocols are highly variable. However, no data are available concerning the variability of responses to quadripulse stimulation (QPS). OBJECTIVE: We assessed the QPS parameters of motor cortical plasticity induction in a systematic manner, and later investigated the variability of QPS using optimal parameters. METHODS: First, two different interburst intervals (IBI) with the same total number of pulses were compared. Next we investigated three different IBIs with a different total number of pulses but with same duration of intervention. We also compared the after-effects of monophasic and biphasic QPS. Finally, variability of QPS was tested in 35 healthy subjects. Twenty motor evoked potentials (MEPs) were measured every 5-10 min for up to one hour after intervention. RESULTS: QPS at an IBI of 5 s produced MEPs changes that are dependent on the interstimulus interval of the four magnetic pulses, consistent with previous reports. Unexpectedly, QPS at an IBI of 2.5 s did not induce any plasticity, even with the same total number of pulses, that is, 1440. QPS at an IBI of 7.5 s produced a variable response but was likely to be comparable to conventional QPS. Biphasic QPS had shorter lasting after-effects compared with monophasic QPS. Finally, the after-effects of QPS were relatively consistent across subjects: more than 80% of subjects responded as expected in the excitatory QPS at an IBI of 5 s. CONCLUSIONS: The IBI, total duration of the procedure and pulse waveform strongly affected the magnitude or duration of the plasticity induced by QPS. In this cohort, 80% of subjects responded to excitatory QPS as expected. PMID- 27692930 TI - Corrections. PMID- 27692932 TI - Who receives oral nutritional supplements in nursing homes? Results from the nutritionDay project. AB - BACKGROUND & AIMS: Oral nutritional supplements (ONS) can be helpful for nursing home (NH) residents to prevent or treat malnutrition. Presently little is known about the use of ONS in NHs and the factors associated with its use. Thus, the aim of this analysis was to describe the use of ONS in NHs participating in the nutritionDay project and to determine characteristics of NH residents receiving ONS. METHODS: Data from nutritionDay (nD), a cross-sectional multicenter study with standardized questionnaires on resident and NH level were analyzed. NH residents participating between 2007 and 2014 aged 65 years or older were included. Unit characteristics (2 variables), general residents' characteristics (18), residents' nutritional status (3) and residents' nutrition (4) were of interest as potential predictors of the use of ONS (no vs yes). Univariate binary logistic regression (LR) analyses were performed for all variables, and significant predictors (p < 0.05) subsequently included in a multivariate analysis (backwards LR). RESULTS: 13.9% of 23,689 NH residents received ONS. Univariate analysis identified all variables as predictors. After multivariate analysis 19 variables remained in the model (Nagelkerke's R2 = 0.319). Odds ratios (OR [95% Confidence Interval]) of receiving ONS were highest in residents receiving supplementary parenteral nutrition (29.05 [14.85-56.81]; however only 1.1% of all participants) and fortified diet (11.91 [8.52-16.64]; 5.7%). The odds ratio of receiving ONS was 3.26 ([2.86-3.71]; 18.3%) for residents being classified as at risk of malnutrition and 4.56 ([3.86-5.40]; 10.0%) for malnourished residents according to NH staff. Low BMI and weight loss in the last year increased the odds of receiving ONS by 2.34 ([1.93-2.84]; 16.0%) and 1.38 ([1.23-1.54]; 32.8%), respectively. Furthermore, increasing age, cognitive and functional impairment, low food intake on nD, neurological disease and cancer were associated with an increased likelihood of the use of ONS. In NH units with a nutritional expert (67.1%) and units performing a nutritional assessment at least once a month (71.6%), the odds of receiving ONS were also significantly increased (1.89 [1.71-2.10] and 1.17 [1.06-1.29]). CONCLUSION: In NHs who participated in the nutritionDay, ONS are used for residents with poor nutritional and functional status and often in combination with other nutritional interventions. Future studies need to clarify the role of NH staff in the prescription and distribution of ONS and focus on the reasons for and adequacy of the use of ONS in NHs. PMID- 27692931 TI - Heart failure and anemia: Effects on prognostic variables. AB - BACKGROUND: Anemia is frequent in heart failure (HF), and it is associated with higher mortality. The predictive power of established HF prognostic parameters in anemic HF patients is unknown. METHODS: Clinical, laboratory, echocardiographic and cardiopulmonary-exercise-test (CPET) data were analyzed in 3913 HF patients grouped according to hemoglobin (Hb) values. 248 (6%), 857 (22%), 2160 (55%) and 648 (17%) patients had very low (<11g/dL), low (11-12 for females, 11-13 for males), normal (12-15 for females, 13-15 for males) and high (>15) Hb, respectively. RESULTS: Median follow-up was 1363days (606-1883). CPETs were always performed safely. Hb was related to prognosis (Hazard ratio (HR)=0.864). No prognostic difference was observed between normal and high Hb groups. Peak oxygen consumption (VO2), ventilatory efficiency (VE/VCO2 slope), plasma sodium concentration, ejection fraction (LVEF), kidney function and Hb were independently related to prognosis in the entire population. Considering Hb groups separately, peakVO2 (very low Hb HR=0.549, low Hb HR=0.613, normal Hb HR=0.618, high Hb HR=0.542) and LVEF (very low Hb HR=0.49, low Hb HR=0.692, normal Hb HR=0.697, high Hb HR=0.694) maintained their prognostic roles. High VE/VCO2 slope was associated with poor prognosis only in patients with low and normal Hb. CONCLUSIONS: Anemic HF patients have a worse prognosis, but CPET can be safely performed. PeakVO2 and LVEF, but not VE/VCO2 slope, maintain their prognostic power also in HF patients with Hb<11g/dL, suggesting CPET use and a multiparametric approach in HF patients with low Hb. However, the prognostic effect of an anemia-oriented follow-up is unknown. PMID- 27692934 TI - Endotracheal intubation during manual inline cervical stabilization performed by nurses. PMID- 27692933 TI - Characterization of oxycodone in vitro metabolism by human cytochromes P450 and UDP-glucuronosyltransferases. AB - The hepatic metabolism of oxycodone by cytochromes P450 (CYP) and the UDP glucuronosyltransferases (UGT), the main metabolic enzymes of phase I and phase II, respectively, was assessed in vitro. The N-demethylation by CYP3A4/5 and the O-demethylation by CYP2D6 in human liver microsomes (HLM) followed Michaelis Menten kinetics, with intrinsic clearances of 1.46MUL/min/mg and 0.35MUL/min/mg, respectively. Although noroxycodone and oxymorphone mainly contribute to the elimination of oxycodone, the simulated total in vivo clearance using in vitro phase I metabolism was underestimated. For the first time, metabolism of oxycodone by UGT was deeply investigated using HLM, recombinant enzymes and selective inhibitors. Oxycodone-glucuronide was mainly produced by UGT2B7 (Km=762+/-153MUM, Vmax=344+/-20 peak area/min/mg) and to a lesser extent by UGT2B4 (Km=2454+/-497MUM, Vmax=201+/-19 peak area/min/mg). Finally, the kinetics of the drug-drug interactions were assessed using two CYP and UGT cocktail approaches. Incubations of HLM with phase I and phase II drug probes showed that oxycodone mainly decreased the in vitro activities of CYP2D6, CYP3A4/5, UGT1A3, UGT1A6 and UGT2B subfamily with an important impact on UGT2B7. PMID- 27692935 TI - Neurodevelopmental outcomes and nutritional strategies in very low birth weight infants. AB - The developing brain of the very low birth weight (VLBW) infant is highly sensitive to effects of the nutritional milieu during the neonatal hospitalization and after discharge. Strategies to optimize nutritional care play an important role in reducing long-term neurodevelopmental morbidities in this population. Currently available interventions to ensure that the unique nutrient requirements of the VLBW infant are met include various dietary fortification strategies and parenteral nutrition. In this article, we review evidence regarding nutritional strategies and their beneficial effects on neurodevelopment in VLBW infants. We also highlight gaps in current knowledge and areas of current investigation that hold promise for improving nutritional care and long-term outcomes. PMID- 27692936 TI - Acacia shrubs respond positively to high severity wildfire: Implications for conservation and fuel hazard management. AB - High severity wildfires pose threats to human assets, but are also perceived to impact vegetation communities because a small number of species may become dominant immediately after fire. However there are considerable gaps in our knowledge about species-specific responses of plants to different fire severities, and how this influences fuel hazard in the short and long-term. Here we conduct a floristic survey at sites before and two years after a wildfire of unprecedented size and severity in the Warrumbungle National Park (Australia) to explore relationships between post-fire growth of a fire responsive shrub genera (Acacia), total mid-story vegetation cover, fire severity and fuel hazard. We then survey 129 plots surrounding the park to assess relationships between mid story vegetation cover and time-since-fire. Acacia species richness and cover were 2.3 and 4.3 times greater at plots after than before the fire. However the same common dominant species were present throughout the study. Mid-story vegetation cover was 1.5 times greater after than before the wildfire, and Acacia species contribution to mid-story cover increased from 10 to 40%. Acacia species richness was not affected by fire severity, however strong positive associations were observed between Acacia and total mid-story vegetation cover and severity. Our analysis of mid-story vegetation recovery showed that cover was similarly high between 2 and 30years post-fire, then decreased until 52years. Collectively, our results suggest that Acacia species are extremely resilient to high severity wildfire and drive short to mid-term increases in fuel hazard. Our results are discussed in relation to fire regime management from the twin perspectives of conserving biodiversity and mitigating human losses due to wildfire. PMID- 27692937 TI - Effects of slope exposure on soil physico-chemical and microbiological properties along an altitudinal climosequence in the Italian Alps. AB - Due to their sensitivity to changing environmental conditions sub- and alpine soils are often monitored in the context of climate change, usually, however, neglecting slope exposure. Therefore, we set up a climosequence-approach to study the effect of exposure and, in general, climate, on the microbial biomass and microbial diversity and activity, comprising five pairs of north (N)- and south (S)-facing sites along an altitudinal gradient ranging from 1200 to 2400m a.s.l. in the Italian Alps (Trentino Alto Adige, Italy). Soil physico-chemical properties were related to microbiological properties (microbial biomass: double strand DNA yield vs. substrate-induced respiration; diversity of bacterial, fungal and archaeal communities: genetic fingerprinting DGGE vs. real-time PCR; microbial activity: basal respiration vs. multiple hydrolytic enzyme assays) to monitor shifts in the diversity and activity of microbial communities as a function of slope exposure and to evaluate the most determinant chemical parameters shaping the soil microbiota. The exposure-effect on several hydrolytic key-enzymes was enzyme-specific: e.g. acid phosphomonoesterase potential activity was more pronounced at the N-facing slope while the activities of alkaline phosphomonoesterase, pyrophosphate-phosphodiesterase and arylsulfatase were higher at the S-facing slope. Furthermore, this exposure-effect was domain specific: bacteria (S>N, altitude-independent); fungi (N~S); and archaea (N>S; altitude-dependent). Additionally, the abiotic parameters shaping the community composition were in general depending on soil depth. Our multidisciplinary approach allowed us to survey the exposure and altitudinal effects on soil physico-chemical and microbiological properties and thus unravel the complex multiple edaphic factor-effects on soil microbiota in mountain ecosystems. PMID- 27692938 TI - False positive and false negative errors in the design and implementation of agri environmental policies: A case study on water quality and agricultural nutrients. AB - When designing and implementing agri-environmental policies to reduce nutrient loss, action programmes may falsely address areas where the nutrient issue from agricultural activity is not currently important and is not likely to become so in the future (a false positive), or may fail to address areas where the agricultural nutrient issue is currently important or may likely become so in the future (a false negative). Based on a case study of the Louros watershed in Greece, this work identifies database and modelling sources of false positives and negatives and proposes a decision making process aimed at minimizing the possibility of committing such errors. The baseline is well simulated and shows that the Louro's watershed falls behind a Good Environmental Status, at least marginally. Simulated mitigation measures show that the river's status can be upgraded to "Good", at least as concerns nitrates and ammonium. Simulated climate change does not seem to exert an important positive or negative effect. Land use changes forecasting considerably less cultivated area have a significant effect on Total Phosphorous but not on nitrates or ammonium concentrations. The non linearity between nutrient disposition (inputs) and nutrient concentration in downstream water bodies (output) and the many factors that affect the nutrient disposition-transportation-concentration chain, highlights the importance of simulating the effects of mitigation actions and of future climate and land use changes before adopting and establishing agri-environmental measures. PMID- 27692939 TI - Detection of Legionella-contaminated aerosols in the vicinity of a bio-trickling filter of a breeding sow facility - A pilot study. AB - The urbanization of agricultural areas results in a reduction of distances between residential buildings and livestock farms. In the public debate, livestock farming is increasingly criticized due to environmental disturbance and odor nuisance originating from such facilities. One method to reduce odor and ammonia is by exhaust air treatment, for example, by biological exhaust air purification processes with bio-trickling filters filled with tap water. Higher temperatures in the summer time and the generation of biofilms are ideal growth conditions for Legionella. However, there are no studies on the presence of Legionella in the water of bio-trickling filters and the release of Legionella containing aerosols. Therefore, the aim of this study was to investigate Legionella in wash water and emitted bioaerosols of a bio-trickling filter system of a breeding sow facility. For this purpose, measurements were carried out using a cyclone sampler. In addition, samples of wash water were taken. Legionella were not found by culture methods. However, using molecular biological methods, Legionella spp. could be detected in wash water as well as in bioaerosol samples. With antibody-based methods, Legionella pneumophila were identified. Further studies are needed to investigate the environmental health relevance of Legionella-containing aerosols emitted by such exhaust air purification systems. PMID- 27692940 TI - The role of seasonal and hydrological conditions in regulating dissolved inorganic nitrogen budgets in a forested catchment in SW Slovenia. AB - During two consecutive years the monitoring of rainfall nitrate (NO3-) and ammonium (NH4+) concentrations, combined with high-frequency measurements of streamwater NO3- concentrations, provided insight into the mechanisms controlling the dissolved inorganic nitrogen (DIN) budgets of the forested Padez stream catchment in SW Slovenia. During both years, the catchment's annual wet atmospheric DIN deposition (12.6 and 13.8kg-N/ha) exceeded the annual DIN export (10.7kg-N/ha and 8.8kg-N/ha). The analysis of the monthly DIN budgets discloses seasonal patterns. In winter and early spring, the catchment behaves as a net source of DIN, whereas during late spring, summer, and early fall the catchment generally behaves as a net sink of the atmospheric DIN. Due to large evapotranspiration in the growth period, most of the DIN remains in the catchment and is flushed during the dormant season. Despite high evapotranspiration and consequently low runoff coefficients characteristic for the Mediterranean climate, large rainfall events in the growth period can cause intensive washout of DIN from the catchment. At a monthly basis, the DIN flushing might exceed the catchment's DIN retention capacity and the catchment might behave as a net source of DIN. Therefore, the hydrological conditions have the ability to shift the catchment's role in regulating the DIN budgets. The high responsiveness of the streamwater NO3- concentration in the growth period indicates a large pool of DIN in the forest soils which can become mobile by runoff formation. Wet atmospheric DIN deposition at the Padez catchment is considerable; highest DIN inputs can be expected when air masses approach the catchment from the southwest to southeast where there are extensive urban areas along the Italian, Slovenian and Croatian coast. However, the Padez catchment does not appear to be approaching N saturation, presumably due to strong internal N cycle in the forest soils. PMID- 27692941 TI - Transport of sulfacetamide and levofloxacin in granular porous media under various conditions: Experimental observations and model simulations. AB - Understanding the fate and transport of antibiotics in porous media can help reduce their contamination risks to soil and groundwater systems. In this work, batch and column experiments were conducted to determine the interactions between two representative antibiotics, sulfacetamide (SA) and levofloxacin (LEV), and sand porous media under various solution pH, humic acid (HA) concentration, grain size, and moisture content conditions. Batch sorption experimental results indicated that the sand had relatively strong bonding affinity to LEV, but little sorption of SA under different pH, HA concentration, grain size conditions. Results from the packed sand column experiments showed that SA had extremely high mobility in the porous media for all combinations of pH, HA concentration, grain size, and moisture content. The mass recovery of SA was higher than 98.5% in all the columns with the exception of the one packed with fine sand (97.2%). The retention of LEV in the columns was much higher and the recovery rates ranged from 0% to 71.1%. Decreases in solution pH, HA concentration, grain size, or moisture content reduced the mobility of LEV in the columns under the tested conditions. These results indicated that type of antibiotics and environmental conditions also played an important role in controlling their fate and transport in porous media. Mathematical models were applied to simulate and interpret experimental data, and model simulations described the interactions between the two antibiotics and sand porous media very well. Findings from this study elucidated the key factors and processes controlling the fate of SA and LEV in porous media, which can inform the prediction and assessment of the environmental risks of antibiotics. PMID- 27692942 TI - Anti-parasite treatment, but not mercury burdens, influence nesting propensity dependent on arrival time or body condition in a marine bird. AB - Arctic wildlife can be exposed to high mercury (Hg) levels, and are also naturally exposed to gastrointestinal parasites that can reduce condition and negatively affect reproductive output and/or survival in similar ways. Importantly, both Hg and parasites are increasing in wildlife in some Arctic regions. We studied the northern common eider duck (Somateria mollissima) to explore how Hg in association with both natural levels and experimentally reduced parasitic infections, affect reproduction and survival. Female eiders were measured, banded, and blood sampled to determine blood Hg burdens, prior to breeding. Propensity to nest, clutch size, nest survival, nest attendance, and return rates were assessed in relation to both Hg burden and parasite treatment. Neither reproduction nor return rates of females varied with Hg concentrations, but females arriving late to the colony, or in low body condition, showed increased nesting propensity when given the anti-parasite treatment as compared to placebo treatment. Our results suggest that parasites can play a critical role in decisions to invest in avian breeding annually, particularly among individuals with a late onset to breeding, and in poor condition.

PMID- 27692944 TI - Alglucosidase alfa enzyme replacement therapy as a therapeutic approach for a patient presenting with a PRKAG2 mutation. AB - OBJECTIVE: PRKAG2 syndrome, an autosomal dominant disorder, is characterized by severe infantile hypertrophic cardiomyopathy and heart rhythm disturbances to cases with a later presentation and a spectrum of manifestations including cardiac manifestations, myopathy and seizures. The cardiac features of PRKAG2 resemble the cardiac manifestations of Pompe disease. We present a patient who was initially diagnosed with Pompe disease and treated with alglucosidase-alfa enzyme replacement therapy (ERT); however, he was eventually diagnosed to carrying a PRKAG2 pathogenic gene mutation; he did not have Pompe disease instead he was a carrier for the common adult leaky splice site mutation in the GAA gene. CASE REPORT: At 2.5months, the patient had hypotonia/generalized muscle weakness, a diagnosis of non-classic infantile Pompe disease was made based on low acid alpha-glucosidase activity and the patient started on ERT at 11months. However, 1month later, the patient began to have seizures. As the patient's medical history was somewhat unusual for infantile Pompe disease, further evaluation was initiated and included a glycogen storage disease sequencing panel which showed that the patient had a pathogenic mutation in PRKAG2 which had been reported previously. ERT was discontinued and patient had a progression of motor deficits. ERT was reinitiated by the treating physician, and a clinical benefit was noted. CONCLUSION: This report outlines the benefits of ERT with alglucosidase alfa in a patient with PRKAG2 syndrome, the decline in his condition when the ERT infusions were discontinued, and the significant positive response when ERT was reinitiated.

AB - Severe, progressive skeletal dysplasia is a major symptom of multiple mucopolysaccharidoses (MPS) types. While a gene therapy approach initiated at birth has been shown to prevent the development of bone pathology in different animal models of MPS, the capacity to correct developed bone disease is unknown. In this study, ex vivo micro-computed tomography was used to demonstrate that bone mass and architecture of murine MPS VII L5 vertebrae were within the normal range at 1month of age but by 2months of age were significantly different to normal. The difference between normal and MPS VII BV/TV increased with age reaching a maximal difference at approximately 4months of age. In mature MPS VII bone BV/TV is increased (51.5% versus 21.5% in normal mice) due to an increase in trabecular number (6.2permm versus 3.8permm in normal mice). The total number of osteoclasts in the metaphysis of MPS VII mice was decreased, as was the percentage of osteoclasts attached to bone. MPS VII osteoblasts produced significantly more osteoprotegerin (OPG) than normal osteoblasts and supported the production of fewer osteoclasts from spleen precursor cells than normal osteoblasts in a co-culture system. In contrast, the formation of osteoclasts from MPS VII spleen monocytes was similar to normal in vitro, when exogenous RANKL and m-CSF was added to the culture medium. Administration of murine beta glucuronidase to MPS VII mice at 4months of age, when bone disease was fully manifested, using lentiviral gene delivery resulted in a doubling of osteoclast numbers and a significant increase in attachment capacity (68% versus 29.4% in untreated MPS VII animals). Bone mineral volume rapidly decreased by 39% after gene therapy and fell within the normal range by 6months of age. Collectively, these results indicate that lentiviral-mediated gene therapy is effective in reversing established skeletal pathology in murine MPS VII.

PMID- 27692947 TI - Assessment of thrombosis in right internal jugular vein after percutaneous superior vena cava catheter insertion during cardiovascular surgery with cardiopulmonary bypass. AB - OBJECTIVE: We evaluated the incidence of percutaneous superior vena cava catheter related thrombosis and identified risk factors for developing the condition in patients undergoing cardiovascular surgery with cardiopulmonary bypass. METHODS: A total of 121 patients were evaluated. A percutaneous superior vena cava catheter was inserted into the right internal jugular vein during cardiovascular surgery with cardiopulmonary bypass. The right internal jugular vein was evaluated using ultrasonography, including cross-sectional area and velocity just before insertion of the percutaneous superior vena cava catheter (preoperative) and 24 hours and 48 hours after its insertion. If an echogenic mass was detected in the right internal jugular vein, the size was measured. RESULTS: The incidence of thrombosis in the right internal jugular vein was 56.2%. Change in the right internal jugular vein cross-sectional area and velocity had no clinical implications. Multiple logistic regression analysis identified age (odds ratio, 1.061; 95% confidence interval, 1.022-1.101; P = .002), superior vena cava catheter indwelling duration (odds ratio, 1.015; 95% confidence interval, 1.008 1.023; P < .001), and amount of transfusion platelet concentrate (odds ratio, 1.155; 95% confidence interval, 1.030-1.295; P = .013) as risk factors for percutaneous superior vena cava catheter-related thrombosis in the right internal jugular vein. CONCLUSIONS: The incidence of percutaneous superior vena cava catheter-related thrombosis was higher than conventional central venous catheter related thrombosis. Risk factors were age, superior vena cava catheter indwelling duration, and amount of transfusion platelet concentrate. PMID- 27692950 TI - Changes in United States heart allocation: A community energized to improve policy. AB - Donor heart allocation in the United States has not evolved in concert with changes in the characteristics of patients on the waiting list or evolution in technology. Data showing the growing population of patients with advanced heart failure coupled with the relatively fixed number of cardiac donors and regional access disparities motivated the United Network for Organ Sharing (UNOS) Thoracic Committee to reexamine candidate prioritization and broader organ sharing. The resultant proposed policy change stratifies patients in a more granular manner based primarily on wait-list mortality and is designed to expand the geographic boundaries to permit greater access to donor hearts for the most critically ill patients awaiting transplant. PMID- 27692949 TI - Does moderate hypothermia really carry less bleeding risk than deep hypothermia for circulatory arrest? A propensity-matched comparison in hemiarch replacement. AB - BACKGROUND: Moderate (MHCA) versus deep (DHCA) hypothermia for circulatory arrest in aortic arch surgery has been purported to reduce coagulopathy and bleeding complications, although there are limited data supporting this claim. This study aimed to compare bleeding-related events after aortic hemiarch replacement with MHCA versus DHCA. METHODS: Patients who underwent hemiarch replacement at a single institution from July 2005 to August 2014 were stratified into DHCA and MHCA groups (minimum systemic temperature <=20 degrees C and >20 degrees C, respectively) and compared. Then, 1:1 propensity matching was performed to adjust for baseline differences. RESULTS: During the study period, 571 patients underwent hemiarch replacement: 401 (70.2%) with DHCA and 170 (29.8%) with MHCA. After propensity matching, 155 patients remained in each group. There were no significant differences between matched groups with regard to the proportion transfused with red blood cells, plasma, platelet concentrates, or cryoprecipitate on the operative day, the rate of reoperation for bleeding, or postoperative hematologic laboratory values. Among patients who received plasma, the median transfusion volume was statistically greater in the DHCA group (6 vs 5 units, P = .01). MHCA also resulted in a slight reduction in median volume of blood returned via cell saver (500 vs 472 mL, P < .01) and 12-hour postoperative chest tube output (440 vs 350, P < .01). Thirty-day mortality and morbidity did not differ significantly between groups. CONCLUSIONS: MHCA compared with DHCA during hermiarch replacement may slightly reduce perioperative blood-loss and plasma transfusion requirement, although these differences do not translate into reduced reoperation for bleeding or postoperative mortality and morbidity. PMID- 27692951 TI - Predictors of survival in adults undergoing extracorporeal membrane oxygenation with severe infections. AB - BACKGROUND: To identify novel factors associated with the survival of septic adults receiving extracorporeal membrane oxygenation (ECMO) to improve patient selection and outcomes. METHODS: Cases were identified from our ECMO registry from 2001 to 2011 if they were >=16 years and received ECMO for life-threatening sepsis. RESULTS: A total of 151 adults with a median (25th-75th percentile) age of 51 (37-63) years were analyzed. Pneumonia (50%), myocarditis (20%), and primary bloodstream infections (15%) were the main types of infection, caused by predominantly nonfermentative Gram-negative bacteria (NFGNB) (26%), Enterobacteriaceae (24%), and Gram-positive cocci (21%). The in-hospital mortality of patients with NFGNB, enteric, and Gram-positive bacterial pneumonias were 100%, 68%, and 14%, respectively. Using the Cox-proportional hazards model, we found that age >75 years (hazard ratio [HR], 1.98, 95% confidence interval [95% CI], 1.30-3.02), pre-ECMO dialysis (HR, 3.20, 95% CI, 1.34-7.63), longer door-to-ECMO intervals (HR, 1.01, 95% CI, 1.00-1.02), venoarterial mode (HR, 2.58, 95% CI, 1.55-4.21), and fungal (HR, 2.83, 95% CI, 1.36-5.88) and NFGNB sepsis (HR, 2.48, 95% CI, 1.44-4.27) were associated with mortality. Gram positive sepsis (HR, 0.20, 95% CI, 0.08-0.57), myocarditis (HR, 0.12, 95% CI, 0.06-0.27), pneumonia (HR, 0.54, 95% CI, 0.30-0.90), and effective empirical antimicrobial therapy were predictive of survival (HR, 0.57, 95% CI, 0.37-0.89); all P < .05. Excluding the 67 heavily premorbid patients, we found that 54% survived ECMO and 42% survived to discharge, with significantly more survivors with door-to-ECMO times of <=96 hours than >96 hours (59% vs 15%, P < .0001). CONCLUSIONS: Better outcomes were associated with door-to ECMO times of 96 hours or less, for Gram-positive rather than Gram-negative sepsis, and for pneumonia rather than primary bloodstream infections. PMID- 27692953 TI - Discussion. PMID- 27692952 TI - Left ventricular assist device as destination therapy in cardiac end-stage dystrophinopathies: Midterm results. AB - OBJECTIVE: We report our experience with the use of a left ventricular assist device (LVAD) as destination therapy (DT) for the management of patients with cardiac end-stage dystrophinopathies. METHODS: From February 2011 to February 2016, 7 patients with dystrophinopathies and dilated cardiomyopathy (DCM) were treated with LVADs at our institution. Median age at surgery was 16.5 years (range, 14.2-23.4 years). All patients were preoperatively evaluated by a multidisciplinary team approach. RESULTS: All patients survived to hospital discharge. The early postoperative course was characterized by abdominal bleeding (1 patient) and retropharyngeal bleeding (1 patient). Because of abdominal or retropharyngeal bleeding, both required postoperative heparin infusion discontinuation for 35 and 33 days, respectively. Among the late complications, 1 child developed osteolysis and infection at the pedestal site of the device, which required surgical displacement; 1 patient required gastrostomy as a result of poor feeding, and another had a cerebral stroke, which was treated with percutaneous thrombus aspiration. The other 2 patients did not show early or late complications. At a median follow-up time of 21.7 months (range, 3-45 months) there have been 3 deaths: 1 patient died of a lung infection after 45 months, 1 died of tracheal bleeding after 29 months, and 1 died of cerebral hemorrhage after 14 months. CONCLUSIONS: Our experience indicates that the use of an LVAD as DT in patients with dystrophinopathies with end-stage DCM is feasible, suggesting that it may be suitable as a palliative therapy for the treatment of these patients with no other therapeutic options. PMID- 27692954 TI - Tissue engineering of the heart: An evolving paradigm. AB - Tissue-engineered regeneration of a failing human heart remains a major challenge, while cardiovascular disease continues to take more lives than all cancers combined. Much has been learned from the basic and clinical studies, with the most interesting developments happening at the interfaces of disciplines. This seems to be the right time to step back and rethink the evolving paradigm of tissue engineering, and to reflect about the most promising directions to take. We clearly need new therapeutic modalities that are effective and yet simple enough to be practical, and the field is looking into the therapeutic potential of stem-progenitor cells, cardiac and vascular, that are enabled by bioactive factors and functionalized biomaterials. PMID- 27692955 TI - Outcome of aortic arch reconstruction in infants with coarctation: Importance of operative approach. AB - OBJECTIVES: Coarctation with hypoplastic aortic arch can be treated with resection and extended end-to-end anastomosis (REEEA) as well as end-to-side anastomosis (ESA). The aim of the study was to review our experience with these techniques in newborns and infants and to assess mid-term outcome with regards to morbidity, mortality, and reintervention rate in relation to operative access and technique. PATIENTS AND METHODS: Retrospective review of hospital charts and surgical reports from 183 consecutive newborns and infants with coarctation and hypoplastic aortic arch with or without ventricular septal defect between 1996 and 2013. Median age at surgery was 15 days (0-345). Lateral thoracotomy was used as operative access in 111 patients; 72 patients had a median sternotomy, 71 of them with cardiopulmonary bypass (ESA n = 30, REEEA n = 41). Fifty-two patients (28.4%) had an additional ventricular septal defect closure. Follow-up data were available for 75.96% with a median follow-up of 6.3 years (0.2-18.16 years). RESULTS: Thirty-day mortality was 0.54% with no late mortality occurring during follow-up. There was 1 severe complication: paraplegia and cerebral hypoxemia after REEEA. Freedom from mortality and reintervention at 10 years was 99.27% and 90.12%, respectively. Lateral thoracotomy as operative access was a risk factor for recurrent obstruction (P = .03). CONCLUSIONS: REEEA and ESA were safe and effective treatments in newborns and infants. In borderline cases, aortic arch reconstruction should be performed through a median sternotomy on bypass.

PMID- 27692958 TI - Usefulness of T2 ratio in the diagnosis and prognosis of cardiac amyloidosis using cardiac MR imaging. AB - PURPOSE: To detect if a difference of T2 ratio, defined as the signal intensity (SI) of the myocardium divided by the SI of the skeletal muscle on T2-weigthed cardiac magnetic resonance (CMR) imaging, exists between patients with systemic amyloidosis, by comparison to control subjects. To determine if a relationship exists between T2 ratio and the overall mortality. MATERIALS AND METHODS: CMR imaging examinations of 73 consecutive patients (48 men, 25 women; mean age, 63 years+/-15[SD]) with amyloidosis and suspicion of CA and 27 control subjects were retrospectively analyzed after institutional review board approval. Final diagnosis of CA was retained in case of histological confirmation of CA, typical pattern of CA on imaging and/or positivity of 99Technetium-hydroxymethylene diphosphonate scintigraphy. Patients were divided in 2 groups according to the presence or the absence of CA. T2 ratios were calculated in patients with and those without CA and in control subjects with using analysis of variance. Prognostic value of T2 ratio was studied with a Kaplan-Meier curve. RESULTS: Thirty-five patients (51%) had CA and 33 (49%) were free from CA. T2 ratio was lower in patients with CA (1.18+/-0.29) than in patients without cardiac involvement (1.37+/-0.35) (P=0.03) and control subjects (1.45+/-0.24) (P=0.004). A T2 ratio of 1.36 was the best threshold value for predicting CA with a sensitivity of 63% and a specificity of 73%. Kaplan-Meier analysis showed a significant relationship between a shortened overall survival and a T2 ratio<1.36. CONCLUSION: Patients with CA exhibit lower T2 ratio on CMR imaging by comparison with patients free of CA and control subjects. PMID- 27692959 TI - Sarah's birth. How the medicalisation of childbirth may be shaped in different settings: Vignette from a study of routine intervention in Jeddah, Saudi Arabia. AB - BACKGROUND: The expansion of the medicalisation of childbirth has been described in the literature as being a global phenomenon. The vignette described in this paper, selected from an ethnographic study of routine intervention in Saudi Arabian hospitals illustrates how the worldwide spread of the bio-medical model does not take place within a cultural vacuum. AIM: To illuminate the ways in which the medicalisation of birth may be understood and practised in different cultural settings, through a vignette of a specific birth, drawn as a typical case from an ethnographic study that investigated clinical decision-making in the second stage of labour in Saudi Arabia. METHODS: Ethnographic data collection methods, including participant observation and interviews. The data presented in this paper are drawn from ethnographic field notes collected during field work in Saudi Arabia, and informed by analysis of a wider set of field notes and interviews with professionals working in this context. FINDINGS: While the medicalisation of care is a universal phenomenon, the ways in which the care of women is managed using routine medical intervention are framed by the local cultural context in which these practices take place. DISCUSSION: The ethnographic data presented in this paper shows the medicalisation of birth thesis to be incomplete. The evidence presented in this paper illustrates how local belief systems are not so much subsumed by the expansion of the bio-medical model of childbirth, rather they may actively facilitate a process of localised reinterpretation of such universalised and standardised practices. In this case, aspects of the social and cultural context of Jeddah operates to intensify the biomedical model at the expense of respectful maternity care. CONCLUSION: In this article, field note data on the birth of one Saudi Arabian woman is used as an illustration of how the medicalisation of childbirth has been appropriated and reinterpreted in Jeddah, Saudi Arabia. PMID- 27692960 TI - Association between Physical Activity and Health-Related Quality of Life in Adults with Type 2 Diabetes. AB - OBJECTIVES: To examine the association between meeting physical-activity recommendations and health-related quality of life (HRQL) in adults with type 2 diabetes. METHODS: Data from the Alberta's Caring for Diabetes cohort were used. Self-report questionnaires were mailed to patients with type 2 diabetes who were living in Alberta, Canada. Weekly moderate-vigorous physical activity (MVPA) was reported using the Godin Leisure Time Physical Activity Questionnaire, and HRQL was reported using the Medical Outcomes Study (MOS) 12-Item Short-Form Health Survey v. 2 (SF-12 v. 2) and the 5-level EuroQol 5-Dimensions (EQ-5D). Based on current guidelines for patients with type 2 diabetes in Canada, participants were grouped according to whether they accrued 150 minutes of MVPA per week. Multivariable linear regression models were used to explore associations between physical activity and HRQL. RESULTS: The mean age of participants (N=1948) was 64.5+/-10.8, and 45% were female. Participants reported a mean of 84.1+/-172.4 minutes of MVPA per week, and 21% (n=416) met recommendations for physical activity. Those who met physical activity recommendations reported higher scores on physical functioning (b=9.58; p<0.001); role-physical (b=8.87; p=0.001); bodily pain (b=5.12; p=0.001); general health (b=6.66; p<0.001); vitality (b=9.05; p<0.001); social functioning (b=3.32; p=0.040); and role-emotional (b=3.08; p=0.010); physical component summary (b=3.31; p<0.001); mental component summary (b=1.43; p=0.001) and EQ-5D-5L index score (b=0.022; p=0.005) compared to those not meeting recommendations. CONCLUSIONS: The majority of the sample did not meet the guidelines for physical activity. Among those who did, a significant positive association was observed with HRQL, particularly physical health.

PMID- 27692962 TI - Impairing Cohesin Smc1/3 Head Engagement Compensates for the Lack of Eco1 Function. AB - The cohesin ring, which is composed of the Smc1, Smc3, and Scc1 subunits, topologically embraces two sister chromatids from S phase until anaphase to ensure their precise segregation to the daughter cells. The opening of the ring is required for its loading on the chromosomes and unloading by the action of Wpl1 protein. Both loading and unloading are dependent on ATP hydrolysis by the Smc1 and Smc3 "head" domains, which engage to form two composite ATPase sites. Based on the available structures, we modeled the Saccharomyces cerevisiae Smc1/Smc3 head heterodimer and discovered that the Smc1/Smc3 interfaces at the two ATPase sites differ in the extent of protein contacts and stability after ATP hydrolysis. We identified smc1 and smc3 mutations that disrupt one of the interfaces and block the Wpl1-mediated release of cohesin from DNA. Thus, we provide structural insights into how the cohesin heads engage with each other. PMID- 27692963 TI - Dynamically Coupled Residues within the SH2 Domain of FYN Are Key to Unlocking Its Activity. AB - Src kinase activity is controlled by various mechanisms involving a coordinated movement of kinase and regulatory domains. Notwithstanding the extensive knowledge related to the backbone dynamics, little is known about the more subtle side-chain dynamics within the regulatory domains and their role in the activation process. Here, we show through experimental methyl dynamic results and predicted changes in side-chain conformational couplings that the SH2 structure of Fyn contains a dynamic network capable of propagating binding information. We reveal that binding the phosphorylated tail of Fyn perturbs a residue cluster near the linker connecting the SH2 and SH3 domains of Fyn, which is known to be relevant in the regulation of the activity of Fyn. Biochemical perturbation experiments validate that those residues are essential for inhibition of Fyn, leading to a gain of function upon mutation. These findings reveal how side-chain dynamics may facilitate the allosteric regulation of the different members of the Src kinase family. PMID- 27692964 TI - The Preserved HTH-Docking Cleft of HIV-1 Integrase Is Functionally Critical. AB - HIV-1 integrase (IN) catalyzes viral DNA integration into the host genome and facilitates multifunctional steps including virus particle maturation. Competency of IN to form multimeric assemblies is functionally critical, presenting an approach for anti-HIV strategies. Multimerization of IN depends on interactions between the distinct subunit domains and among the flanking protomers. Here, we elucidate an overlooked docking cleft of IN core domain that anchors the N terminal helix-turn-helix (HTH) motif in a highly preserved and functionally critical configuration. Crystallographic structure of IN core domain in complex with Fab specifically targeting this cleft reveals a steric overlap that would inhibit HTH-docking, C-terminal domain contacts, DNA binding, and subsequent multimerization. While Fab inhibits in vitro IN integration activity, in vivo it abolishes virus particle production by specifically associating with preprocessed IN within Gag-Pol and interfering with early cytosolic Gag/Gag-Pol assemblies. The HTH-docking cleft may offer a fresh hotspot for future anti-HIV intervention strategies. PMID- 27692965 TI - Structural Basis of Interfacial Flexibility in Fibrin Oligomers. AB - Fibrin is a filamentous network made in blood to stem bleeding; it forms when fibrinogen is converted into fibrin monomers that self-associate into oligomers and then to polymers. To gather structural insights into fibrin formation and properties, we combined high-resolution atomic force microscopy of fibrin(ogen) oligomers and molecular modeling of crystal structures of fibrin(ogen) and its fragments. We provided a structural basis for the intermolecular flexibility of single-stranded fibrin(ogen) oligomers and identified a hinge region at the D:D inter-monomer junction. Following computational reconstruction of the missing portions, we recreated the full-atomic structure of double-stranded fibrin oligomers that was validated by quantitative comparison with the experimental images. We characterized previously unknown intermolecular binding contacts at the D:D and D:E:D interfaces, which drive oligomerization and reinforce the intra and inter-strand connections in fibrin besides the known knob-hole bonds. The atomic models provide valuable insights into the submolecular mechanisms of fibrin polymerization. PMID- 27692967 TI - Review of head-to-head study designs in rheumatoid arthritis. AB - OBJECTIVE: Treatment options available to patients with rheumatoid arthritis (RA) are ever-changing, and understanding the similarities and differences of efficacy and safety between different RA therapies is of key importance in order to facilitate treatment decisions by both the patient and physician. Very few head to-head, peer-reviewed trials exist; instead, evidence for efficacy of treatments is often ascertained from placebo-controlled trials, registries and meta analyses, which often do not sufficiently address the relative effectiveness of two medications. METHODS: A targeted review of indirect comparison methods, and ongoing and published clinical studies assessing the efficacy and safety, and the comparative efficacy and safety of biologic disease modifying antirheumatic drugs in RA. RESULTS: Critical elements that should be considered when designing head to head trials are described using examples of true head-to-head and placebo controlled randomized controlled trials (RCTs). The appropriate use of head-to head trial designs is demonstrated by reviewing different examples of well designed clinical trials, and an overview is presented of the challenges associated with indirect comparisons. This review also examines the use of studies comparing therapies to placebo, highlighting the difficulties associated with the interpretation of these studies. CONCLUSIONS: For comparative trials to contribute to evidence-based decision making in the treatment of RA, patient populations and treatment regimens as similar as possible to those used in routine clinical practice should be employed and the trial should be appropriately designed to answer the specific question asked. PMID- 27692968 TI - A geometric morphometric evaluation of the Belanglo 'Angel' facial approximation. AB - In August 2011, a 2D facial approximation was undertaken of remains discovered in Australia's Belanglo State Forrest; in October 2015, the young woman was identified. Referencing three photographs of the young woman as she appeared in life and a database of 64 sex, age, head pose and population matched images, the facial approximation is evaluated for relative shape accuracy through the application of geometric morphometrics. The results are that the facial approximation is significantly similar to the images of the young woman in facial morphology (p=0.002) when most of the variance due to depicted head pose is removed from the analyses. The geometric morphometric analyses, however, also highlight the facial approximation's face and feature discrepancies, some of which would have likely disrupted familiar face recognition. Although predominantly verified methods were applied in 2011, they are limited in their predictive accuracy, not every feature of the face has a verified method to apply, and practitioner errors as well as photographic distortions are apparent. Furthermore, an assumption that the verified methods require inter-feature agreement (in this instance eye spacing and mouth width) was proved to be false. Overall this study shows that it is possible to assess the morphological accuracy of a forensic facial approximation when a number of antemortem images are available, though the influence of photographic distortion within 2D photographs will always preclude a precise metric assessment. PMID- 27692966 TI - Erosive osteoarthritis: A systematic analysis of definitions used in the literature. AB - BACKGROUND: Erosive osteoarthritis (EOA) is a commonly invoked diagnosis representing an important variant of hand osteoarthritis (OA). There is increasing literature on the prevalence, risk factors, etiology, and management of EOA. METHODS: We systematically reviewed the literature to assess variability in the diagnostic definitions used to define EOA in these studies. RESULTS: We reviewed 336 articles and found 62 articles citing diagnostic definitions for EOA. Radiographic appearance was the most commonly used criterion, but there was little agreement on the details or extent of the radiographic changes. Overall, 56 of the 62 studies included clinical features in the diagnostic definitions, yet these features varied considerably. Exclusion criteria were mentioned in 43 of the studies. CONCLUSION: Based on the widely disparate definitions of EOA, we urge caution in interpretation of this literature, and propose that further understanding of EOA will require consensus on its definition. PMID- 27692969 TI - Quantitative evaluation of pancreatic tumor fibrosis using shear wave elastography. AB - BACKGROUND & AIMS: There is no established non-invasive method for diagnosis of pancreatic fibrosis. Shear wave elastography (SW-EG) may be a candidate for this purpose. The aims of this study were to assess the reproducibility of SW-EG in the normal imaging pancreas (Phase 1) and to evaluate the diagnostic performance of SW-EG for pancreatic fibrosis classified histologically (Phase 2). METHODS: Phase 1: This included 127 cases that underwent SW-EG of the normal imaging pancreas. SW-EG was measured at least five times in the pancreatic parenchyma and the median of repeated measurements was defined as the pancreatic elastic modulus (PEM). Phase 2: This included 53 cases that underwent SW-EG of the pancreatic parenchyma preoperatively and in which pancreas parenchyma were evaluated histologically. Histological fibrosis was graded in 4 stages: normal, mild, moderate, and severe. RESULTS: Phase 1: Median PEM in the head, body, and tail of the pancreas were 3.23, 3.17, and 2.91 kPa, respectively, with no significant difference among regions (P = 0.554). The intraclass correlation coefficient showed good reproducibility (rho = 0.71) after 5 measurements. Phase 2: There was a significant positive correlation between PEM and the histological pancreatic fibrosis stage (rs = 0.63, P < 0.001). Areas under the receiver operating characteristic curve for the accuracy of SW-EG for diagnosis of pancreatic fibrosis were 0.85 (>=mild), 0.84 (>=moderate), and 0.87 (severe). CONCLUSION: SW EG can be used to determine the stage of pancreatic fibrosis non-invasively with high accuracy and reproducibility. PMID- 27692971 TI - Incidence and Etiology of Sudden Cardiac Arrest and Death in High School Athletes in the United States. AB - OBJECTIVE: To determine the incidence and etiology of sudden cardiac arrest and death (SCA/D) in US high school athletes. PATIENTS AND METHODS: A prospective media database of SCA/D was queried for cases aged 14 to 18 years from 7 states over 6 school years (September 1, 2007, to August 30, 2013). Event details were investigated to determine participation on a high school athletic team, sex, sport, and occurrence during school-sponsored activity or exertion. National sports participation numbers were used and a conversion factor was applied to account for multisport athletes. Autopsy reports were reviewed and cause of death was adjudicated by an expert panel. RESULTS: A total of 16,390,409 million athlete-seasons representing 6,974,640 athlete-years (AY) were examined, encompassing 36% of the total US high school athlete population. A total of 104 cases of SCA/D were identified (35 SCA with survival and 69 sudden cardiac deaths [SCDs]). The rate of SCD was 1:101,082 AY and of SCA/D 1:67,064 AY. Eighty-eight percent (92) of events occurred in male athletes. The rate of SCA/D in male athletes was 1:44,832 AY and in female athletes 1:237,510 AY (incidence rate ratio, 5.3; 95% CI, 2.9-10.6; P<.001). Men's basketball was the highest risk sport with an SCA/D incidence of 1:37,087 AY followed by men's football at 1:86,494 AY. Men's basketball and football athletes accounted for 57% (39) of deaths. Eighty percent of SCDs (55 of 69) were exertional and 55% (38 of 69) occurred while playing for a school-sponsored team. Autopsy reports were obtained in 73% (50) of cases. The most common findings of autopsy were idiopathic left ventricular hypertrophy or possible cardiomyopathy (13 of 50 [26%]), autopsy negative sudden unexplained death (9 of 50 [18%]), hypertrophic cardiomyopathy (7 of 50 [14%]), and myocarditis (7 of 50 [14%]). CONCLUSION: The rate of SCA/D in male high school athletes was 1:44,832 AY, with almost half due to possible or confirmed cardiomyopathy disease. It is likely that many cases were not identified because of reliance on media reports, and these numbers represent a minimum estimate. PMID- 27692970 TI - Increasing Incidence of Melanoma in the Elderly: An Epidemiological Study in Olmsted County, Minnesota. AB - OBJECTIVE: To estimate the age- and sex-adjusted incidence of melanoma in adults 61 years or older in Olmsted County, Minnesota, from 1970 through 2009. PATIENTS AND METHODS: Using Rochester Epidemiology Project resources, 397 patients were identified who were 61 years or older and who received a first lifetime diagnosis of melanoma from January 1, 1970, through December 31, 2009, in Olmsted County. The incidence of melanoma and the overall and disease-specific survival rates were compared by age, sex, year of diagnosis, and stage of disease. RESULTS: From 1970 through 2009, age- and sex-adjusted incidence increased significantly (P<.001) from 17.0 (95% CI, 8.6-25.4) to 124.6 (95% CI, 108.9-140.3) per 100,000 person-years, with a 4-fold increase in women and a more than 11-fold increase in men. In men, incidence rates increased with age (P<.001) and over time (P<.001). In women, incidence rates increased over time (P<.001) but were constant across all age groups studied (P=.90). The dramatic increase in the incidence of melanoma was observed mainly for stages 0 and I tumors in both men and women (>55 fold increase). Disease-specific survival increased across the decades (P<.001); when year of diagnosis was compared to mortality, hazard ratios were 0.94 (95% CI, 0.90-0.99; P=.010) and 0.93 (95% CI, 0.89-0.98; P=.006) for men and women, respectively. CONCLUSION: The incidence of melanoma in older men and women increased significantly over the past 4 decades in Olmsted County, with men experiencing higher rates of increase than did women.

AB - For adolescents with diabetes, ineffective health care transition to adult health services may result in suboptimal adherence to medical supervision, leading to poor glycemic control, increased diabetes complications, and hospitalization. Despite national recommendations, few youth receive the needed preparation to transition to adult health services. A data transition registry was created at a large Midwest urban academic medical center to identify patients 14 years and older with Type 1 diabetes. Thirty-nine patients with Type 1 diabetes were identified, and 33 were eligible to begin transition planning. Baseline Transition Readiness Assessment Questionnaires (TRAQs) were completed in 21 (64%) of the 33 identified patients, with a mean TRAQ skill score of 66.62 out of 100. There was no correlation between better TRAQ scores and hemoglobin A1c level. Participants had lower baseline TRAQ scores for appointment keeping and tracking health issues. Participants were confident managing daily activities, talking with providers, and managing medications. PMID- 27692974 TI - Bundled Payment for Gastrointestinal Hemorrhage. PMID- 27692973 TI - Waking up is the hardest thing I do all day: Sleep inertia and sleep drunkenness. AB - The transition from sleep to wake is marked by sleep inertia, a distinct state that is measurably different from wakefulness and manifests as performance impairments and sleepiness. Although the precise substrate of sleep inertia is unknown, electroencephalographic, evoked potential, and neuroimaging studies suggest the persistence of some features of sleep beyond the point of awakening. Forced desynchrony studies have demonstrated that sleep inertia impacts cognition differently than do homeostatic and circadian drives and that sleep inertia is most intense during awakenings from the biological night. Recovery sleep after sleep deprivation also amplifies sleep inertia, although the effects of deep sleep vary based on task and timing. In patients with hypersomnolence disorders, especially but not exclusively idiopathic hypersomnia, a more pronounced period of confusion and sleepiness upon awakening, known as "sleep drunkenness", is common and problematic. Optimal treatment of sleep drunkenness is unknown, although several medications have been used with benefit in small case series. Difficulty with awakening is also commonly endorsed by individuals with mood disorders, disproportionately to the general population. This may represent an important treatment target, but evidence-based treatment guidance is not yet available. PMID- 27692975 TI - Exposure of juvenile turbot (Scophthalmus maximus) to silver nanoparticles and 17alpha-ethinylestradiol mixtures: Implications for contaminant uptake and plasma steroid hormone levels. AB - Combined exposure to engineered nanoparticles (ENPs) and anthropogenic contaminants can lead to changes in bioavailability, uptake and thus effects of both groups of contaminants. In this study we investigated effects of single and combined exposures of silver (Ag) nanoparticles (AgNPs) and the synthetic hormone 17alpha-ethinylestradiol (EE2) on tissue uptake of both contaminants in juvenile turbot (Scophthalmus maximus). Silver uptake and tissue distribution (gills, liver, kidney, stomach, muscle and bile) were analyzed following a 14-day, 2-h daily pulsed exposure to AgNPs (2 MUg L-1 and 200 MUg L-1), Ag+ (50 MUg L-1), EE2 (50 ng L-1) and AgNP + EE2 (2 or 200 MUg L-1+50 ng L-1). Effects of the exposures on plasma vitellogenin (Vtg) levels, EE2 and steroid hormone concentrations were investigated. The AgNP and AgNP + EE2 exposures resulted in similar Ag concentrations in the tissues, indicating that combined exposure did not influence Ag uptake in tissues. The highest Ag concentrations were found in gills. For the Ag+ exposed fish, the highest Ag concentrations were measured in the liver. Our results show dissolution processes of AgNPs in seawater, indicating that the tissue concentrations of Ag may partly originate from ionic release. Plasma EE2 concentrations and Vtg induction were similar in fish exposed to the single contaminants and the mixed contaminants, indicating that the presence of AgNPs did not significantly alter EE2 uptake. Similarly, concentrations of most steroid hormones were not significantly altered due to exposures to the combined contaminants versus the single compound exposures. However, high concentrations of AgNPs in combination with EE2 caused a drop of estrone (E1) (female fish) and androstenedione (AN) (male and female fish) levels in plasma below quantification limits. Our results indicate that the interactive effects between AgNPs and EE2 are limited, with only high concentrations of AgNPs triggering synergistic effects on plasma steroid hormone concentrations in juvenile turbots. PMID- 27692976 TI - Pharmacodynamic Effects of Single and Multiple Doses of Empagliflozin in Patients With Type 2 Diabetes. AB - PURPOSE: Our aim was to investigate the effects of the sodium glucose cotransporter 2 inhibitor empagliflozin on urinary and serum glucose and electrolytes, urinary volume, osmolality, and the renin-angiotensin system in patients with type 2 diabetes. METHODS: In an open-label study, 22 patients receiving metformin (median age 56 years; range 40-65 years) received empagliflozin 25 mg once daily for 5 days. Food, fluid, and sodium intake were standardized for 3 days before and during treatment. FINDINGS: Twenty patients completed treatment. After single and multiple doses of empagliflozin, mean (SE) changes from baseline in 24-hour urinary glucose excretion were 463.3 (57.3) mmol/d and 599.5 (60.0) mmol/d, respectively (83.5 [10.3] g/d and 108.0 [10.8] g/d, respectively) (both P < 0.001), and in fasting serum glucose concentration were -1.8 (0.4) mmol/L and -1.1 (0.3) mmol/L, respectively (both P < 0.001). After a single dose, mean (SE) change from baseline in urine sodium excretion was 45.3 (9.6) mmol/d (P < 0.001), and in urine volume was 341.0 (140.5) g/d (P = 0.025), but there were no changes compared with baseline in either parameter after multiple doses. There were no changes in plasma renin or serum aldosterone with single or multiple doses of empagliflozin. There was a nonsignificant reduction in weight after a single dose of empagliflozin and a mean (SE) change of -1.4 (0.5) kg after multiple doses (P = 0.020). IMPLICATIONS: Empagliflozin 25 mg increased urinary glucose excretion and decreased serum glucose and weight with transient natriuresis and increases in urine volume, without significant changes in the renin-angiotensin system.

PMID- 27692977 TI - Comparison of Inhaled Antibiotics for the Treatment of Chronic Pseudomonas aeruginosa Lung Infection in Patients With Cystic Fibrosis: Systematic Literature Review and Network Meta-analysis. AB - PURPOSE: In Europe, 4 inhaled antibiotics (tobramycin, colistimethate sodium, aztreonam, and levofloxacin) are currently approved for the treatment of chronic Pseudomonas aeruginosa lung infection in patients with cystic fibrosis (CF). Levofloxacin inhalation solution (LIS) is the most recently approved inhaled antibiotic for adult patients with CF. A systematic literature review and Bayesian network meta-analysis (NMA) was conducted to compare the relative short term (4 weeks) and long-term (24 weeks) outcomes of these inhaled antibiotics versus LIS. METHODS: A systematic literature search was conducted on February 16, 2016, using EMBASE and Medline via OvidSP. All randomized controlled trials comparing any of the aforementioned inhaled antibiotics with 4 or 24 weeks of follow-up were evaluated. NMA was performed for the following outcomes: relative and absolute percent changes from baseline in forced expiratory volume in 1 second (FEV1%) predicted, change in P aeruginosa sputum density, respiratory symptoms score from the CF questionnaire-revised, hospitalization, additional antibiotics use, and study withdrawal rates. RESULTS: Of the 685 articles identified, 7 unique studies were included in the 4 weeks' NMA and 9 unique studies were included in the 24 weeks' NMA. Aztreonam was predicted to result in the greatest numerically increase in FEV1% predicted at 4 weeks, whereas LIS were predicted to be numerically greater than colistimethate sodium, tobramycin inhaled solution (TIS), and tobramycin inhaled powder (TIP). However, all of the 95% credibility intervals (CrIs) of these comparisons included zero. At 24 weeks, none of the treatments was significantly more effective than LIS. The estimates for the mean change from baseline to 24 weeks in relative FEV1% versus LIS was 0.55 (95% CrI, -3.91 to 2.80) for TIS, -2.36 (95% CrI, -7.32 to 2.63) for aztreonam, -2.95 (95% CrI, -10.44 to 4.51) for TIP, and -9.66 (95% CrI, -15.01 to -4.33) for placebo. Compared with LIS, the odds ratio for hospitalization at 24 weeks was 1.92 (95% CrI, 1.01-3.30) for TIS, 2.25 (95% CrI, 1.01-4.34) for TIP, and 3.16 (95% CrI, 1.53-5.78) for placebo, all statistically worse than LIS. P aeruginosa sputum density scores, additional use of antipseudomonal antibiotics, and study withdrawal rates were comparable among all inhaled antibiotics at all times. IMPLICATIONS: Based on this NMA, the analyses for many of the outcomes did not provide significant evidence to indicate that the other approved inhaled antibiotics were more effective than LIS for the treatment of chronic P aeruginosa lung infection in patients with CF. Study withdrawal rates seemed to be comparable among these inhaled antibiotics. PMID- 27692979 TI - Fatal Kounis syndrome with stent thrombosis secondary to amoxicillin/clavulanic acid use: A case report and literature review. AB - Anaphylactic reactions are often induced by drugs, and the most frequent ones are penicillin derivates. The concurrence of acute coronary syndrome with hypersensitivity and anaphylactic or anaphylactoid reactions constitutes the Kounis syndrome. We report a case of a coronary stent thrombosis with a fatal outcome complicating an anaphylactic shock induced by amoxicillin-clavulanic acid association. A 58-year-old woman with a history of triple coronary stenting was treated by amoxicillin/clavulanic acid association for pharyngitis. One hour after the first drug intake, she developed an anaphylactic shock with acute constricting chest pain. She received intravenous hydrocortisone and was transferred to emergency department. The patient received epinephrine intravenously with fluid perfusion and oxygen. Electrocardiogram showed Pardee waves in the anterior precordial leads. Cardiac enzyme levels (troponin I) were disturbed. The patient was transferred to the coronary care unit with a diagnosis of acute myocardial infarction. The coronary angiography revealed anterior interventricular stent thrombosis. The patient experienced a cardiogenic shock with an important hemodynamic repercussion, and she died few hours later despite emergency care. The responsibility of amoxicillin-clavulanic acid association was retained in the genesis of this anaphylactic shock in front of a suggestive delay, a compatible evolution and a high semiotic score. Amoxicillin/clavulanic acid use may cause Kounis syndrome. The use of epinephrine is a challenging decision. We suggest that Kounis syndrome should be considered in the differential diagnosis of acute coronary syndrome. PMID- 27692978 TI - Intolerance to non-steroidal anti-inflammatory drugs. PMID- 27692980 TI - [Automated grouping of terms associated to cardiac valve fibrosis in MedDRA]. AB - AIM: To propose an alternative approach for building custom groupings of terms that complements the usual approach based on both hierarchical method (selection of reference groupings in medical dictionary for regulatory activities [MedDRA]) and/or textual method (string search), for case reports extraction from a pharmacovigilance database in response to a safety problem. Here we take cardiac valve fibrosis as an example. METHODS: The list of terms obtained by an automated approach, based on querying ontology of adverse drug reactions (OntoADR), a knowledge base defining MedDRA terms through relationships with systematized nomenclature of medicine-clinical terms (SNOMED CT) concepts, was compared with the reference list consisting of 53 preferred terms obtained by hierarchical and textual method. Two queries were performed on OntoADR by using a dedicated software: OntoADR query tools. Both queries excluded congenital diseases, and included a procedure or an auscultation method performed on cardiac valve structures. Query 1 also considered MedDRA terms related to fibrosis, narrowing or calcification of heart valves, and query 2 MedDRA terms described according to one of these four SNOMED CT terms: "Insufficiency", "Valvular sclerosis", "Heart valve calcification" or "Heart valve stenosis". RESULTS: The reference grouping consisted of 53 MedDRA preferred terms. Our automated method achieved recall of 79% and precision of 100% for query 1 privileging morphological abnormalities, and recall of 100% and precision of 96% for query 2 privileging functional abnormalities. CONCLUSION: An alternative approach to MedDRA reference groupings for building custom groupings is feasible for cardiac valve fibrosis. OntoADR is still in development. Its application to other adverse reactions would require significant work for a knowledge engineer to define every MedDRA term, but such definitions could then be queried as many times as necessary by pharmacovigilance professionals. PMID- 27692981 TI - The pertussis hypothesis: Bordetella pertussis colonization in the pathogenesis of Alzheimer's disease. AB - While a number of endogenous risk factors including age and genetics are established for Alzheimer's disease (AD), identification of acquired, potentially preventable or treatable causes, remains limited. In this paper, we review three epidemiologic case studies and present extensive biologic, immunologic and anatomic evidence to support a novel hypothesis that Bordetella pertussis (BP), the bacterium better known to cause whooping cough, is an important potential cause of AD. Cross-cultural documentation of nasopharyngeal subclinical BP colonization reflecting BP-specific mucosal immunodeficiency, proximate anatomy of intranasal mucosal surfaces to central nervous system (CNS) olfactory pathways, and mechanisms by which BP and BP toxin account for all hallmark pathology of AD are reviewed, substantiating biologic plausibility. Notably, respiratory BP infection and BP toxin secreted from subclinical BP colonization can account for the initiation and accumulation of amyloid beta plaques and tau tangles. Additional mechanisms consistent with the immunobiologic effects of subclinical BP colonization include microglial activation and inflammation, atrophy and neurodegeneration, excitotoxicity, distinctive anatomic distribution and sequential spread of disease, impaired glucose utilization, and other characteristic CNS pathology of AD. We conclude by assessing the evidence for causation against the Bradford Hill criteria, and advocate for further investigation into the potential role of BP in the etiology of AD. PMID- 27692982 TI - mTORC1 inhibition with rapamycin exacerbates adipose tissue inflammation in obese mice and dissociates macrophage phenotype from function. AB - Genetic- and diet-induced obesity and insulin resistance are associated with an increase in mechanistic target of rapamycin complex (mTORC) 1 activity in adipose tissue. We investigated herein the effects of pharmacological mTORC1 inhibition in the development of adipose tissue inflammation induced by high-fat diet (HFD) feeding, as well as in the polarization, metabolism and function of bone marrow derived macrophages (BMDM). For this, C57BL/6J mice fed with a standard chow diet or a HFD (60% of calories from fat) and treated with either vehicle (0.1% Me2SO, 0.2% methylcellulose) or rapamycin (2mg/kg/ day, gavage) during 30days were evaluated for body weight, adiposity, glucose tolerance and adipose tissue inflammation. Although rapamycin did not affect the increase in body weight and adiposity, it exacerbated the glucose intolerance and adipose tissue inflammation induced by HFD feeding, as evidenced by the increased adipose tissue percentage of M1 macrophages, naive and activated cytotoxic T lymphocytes, and mRNA levels of proinflammatory molecules, such as TNF-alpha, IL-6 and MCP-1. In BMDM in vitro, pharmacological mTORC1 inhibition induced phosphorylation of NFkappaB p65 and spontaneous polarization of macrophages to a proinflammatory M1 profile, while it impaired M2 polarization induced by IL-4+IL-13, glycolysis and phagocytosis. Altogether, these findings indicate that mTORC1 activity is an important determinant of adipose tissue inflammatory profile and macrophage plasticity, metabolism and function.

AB - Extracellular signals are often transduced by dynamic signaling complexes ("signalosomes") assembled by oligomerizing hub proteins following their recruitment to signal-activated transmembrane receptors. A paradigm is the Wnt signalosome, which is assembled by Dishevelled via reversible head-to-tail polymerization by its DIX domain. Its activity causes stabilization of beta catenin, a Wnt effector with pivotal roles in animal development and cancer. How Wnt triggers signalosome assembly is unknown. Here, we use structural analysis, as well as biophysical and cell-based assays, to show that the DEP domain of Dishevelled undergoes a conformational switch, from monomeric to swapped dimer, to trigger DIX-dependent polymerization and signaling to beta-catenin. This occurs in two steps: binding of monomeric DEP to Frizzled followed by DEP domain swapping triggered by its high local concentration upon Wnt-induced recruitment into clathrin-coated pits. DEP domain swapping confers directional bias on signaling, and the dimerization provides cross-linking between Dishevelled polymers, illustrating a key principle underlying signalosome formation. PMID- 27692985 TI - Monoubiquitination of Histone H2B Blocks Eviction of Histone Variant H2A.Z from Inducible Enhancers. AB - Covalent modifications of histones play a crucial role in the regulation of gene expression. Histone H2B monoubiquitination has mainly been described as a regulator of transcription elongation, but its role in transcription initiation is poorly documented. We investigated the role of this histone mark (H2Bub1) on different inducible enhancers, in particular those regulated by estrogen receptor alpha, by loss- and gain-of-function experiments with the specific E3-ubiquitin ligase complex of H2B: RNF20/RNF40. RNF20/RNF40 overexpression causes repression of the induced activity of these enhancers. Genome-wide profiles show that H2Bub1 levels are negatively correlated with the accessibility of enhancers to transcriptional activators. We found that the chromatin association of histone variant H2A.Z, which is evicted from enhancers for transcriptional activation, is stabilized by H2Bub1 by impairing access of the chromatin remodeler INO80. We propose that H2Bub1 acts as a gatekeeper of H2A.Z eviction and activation of inducible enhancers. PMID- 27692986 TI - USP38 Inhibits Type I Interferon Signaling by Editing TBK1 Ubiquitination through NLRP4 Signalosome. AB - TBK1 is a component of the type I interferon (IFN) signaling pathway, yet the mechanisms controlling its activity and degradation remain poorly understood. Here we report that USP38 negatively regulates type I IFN signaling by targeting the active form of TBK1 for degradation in vitro and in vivo. USP38 specifically cleaves K33-linked poly-ubiquitin chains from TBK1 at Lys670, and it allows for subsequent K48-linked ubiquitination at the same position mediated by DTX4 and TRIP. Knockdown or knockout of USP38 increases K33-linked ubiquitination, but it abrogates K48-linked ubiquitination and degradation of TBK1, thus enhancing type I IFN signaling. Our findings identify an essential role for USP38 in negatively regulating type I IFN signaling, and they provide insights into the mechanisms by which USP38 regulates TBK1 ubiquitination through the NLRP4 signalosome. PMID- 27692987 TI - Neurocognitive Function in Children with Primary Hypertension. AB - OBJECTIVE: To compare neurocognitive test performance of children with primary hypertension with that of normotensive controls. STUDY DESIGN: Seventy-five children (10-18 years of age) with newly diagnosed, untreated hypertension and 75 frequency-matched normotensive controls had baseline neurocognitive testing as part of a prospective multicenter study of cognition in primary hypertension. Subjects completed tests of general intelligence, attention, memory, executive function, and processing speed. Parents completed rating scales of executive function and the Sleep-Related Breathing Disorder scale of the Pediatric Sleep Questionnaire (PSQ-SRBD). RESULTS: Hypertension and control groups did not differ significantly in age, sex, maternal education, income, race, ethnicity, obesity, anxiety, depression, cholesterol, glucose, insulin, and C-reactive protein. Subjects with hypertension had greater PSQ-SRBD scores (P = .04) and triglycerides (P = .037). Multivariate analyses showed that hypertension was independently associated with worse performance on the Rey Auditory Verbal Learning Test (List A Trial 1, P = .034; List A Total, P = .009; Short delay recall, P = .013), CogState Groton Maze Learning Test delayed recall (P = .002), Grooved Pegboard dominant hand (P = .045), and Wechsler Abbreviated Scales of Intelligence Vocabulary (P = .016). Results indicated a significant interaction between disordered sleep (PSQ-SRBD score) and hypertension on ratings of executive function (P = .04), such that hypertension heightened the association between increased disordered sleep and worse executive function. CONCLUSIONS: Youth with primary hypertension demonstrated significantly lower performance on neurocognitive testing compared with normotensive controls, in particular, on measures of memory, attention, and executive functions. PMID- 27692988 TI - An outbreak of Kyasanur forest disease in the Wayanad and Malappuram districts of Kerala, India. AB - Kyasanur forest disease (KFD) is a zoonotic viral haemorrhagic fever and has been endemic to Karnataka State, India. Outbreaks of KFD were reported in new areas of Wayanad and Malappuram districts of Kerala, India during 2014-2015. Investigation of the outbreaks was carried out in these districts during May 2015. The line list data of KFD cases available with District Medical Office, Wayanad were analysed. Case investigation was carried out to determine the risk factors associated with the outbreak and possible site of contraction infections. Ticks from the forest floor were collected in areas associated with monkey deaths by flagging method to estimate species abundance. Of 102 confirmed cases of KFD reported in Wayanad, 91% were adults aged >15years. About 43% of the cases were from the areas of Poothady Primary Health Centre (PHC) followed by Chethalayam PHC (22%). Most of the affected individuals belong to Kattunayakan tribe, dependent on forest for their livelihood. Those tribes are engaged in trench digging and fire line works in summer months and hence are at a higher risk. In Malappuram, the Cholanaickan tribe, are under high risk of exposure to infected ticks as they live deep in the forest and trap monkeys for game meat. High abundance of Haemaphysalis spinigera and H. turturis, the established vectors of KFD virus was recorded in all affected areas. Incidence of KFD cases/monkey deaths and high abundance of Haemaphysalis vectors in the forest ranges of Wayanad and Malappuram districts indicate that the area has become receptive for KFD outbreaks. Preventive measures (vaccination of high risk groups) coupled with intensive health education should be carried out prior to transmission season. PMID- 27692990 TI - Body adiposity predictors of vitamin D status in nondialyzed patients with chronic kidney disease: A cross-sectional analysis in a tropical climate city. AB - OBJECTIVES: The association of vitamin D status with high body adiposity is poorly investigated in the chronic kidney disease (CKD) population. The aim of the present study was to describe vitamin D status and to identify body adiposity predictors of vitamin D deficiency, in a nondialyzed CKD population inhabiting a tropical city. METHODS: This cross-sectional study included patients with CKD, defined as estimated glomerular filtration rate (eGFR) <60 mL/min, regularly treated by an interdisciplinary team in an outpatient university clinic, set in a Brazilian city (latitude: 22 degrees 54'S; 43 degrees 12'W). Adiposity parameters analyzed were body mass index (BMI), total body adiposity (dual-energy x-ray absorptiometry [DXA] and body adiposity index [BAI]), and central body adiposity (DXA-trunk fat and waist-to-height ratio [WHtR]). Laboratory parameters included serum concentrations of 25-hydroxyvitamin D, phosphate, parathyroid hormone, and insulin (insulin resistance [IR evaluation: homeostasis model assessment; HOMA]). RESULTS: We studied 244 patients (54.9% men; n = 134) with median eGFR = 29.1 mL/min and BMI 26.1 kg/m2, comprising 58.2% (n = 142) with overweight/obesity. The vitamin D status was sufficient (>=30 ng/dL) in 43%, insufficient (20-30 ng/dL) in 37%, and deficient (<20 ng/dL) in 20%. Total body adiposity was the independent predictor of vitamin D deficiency (DXA: odds ratio [OR], 2.3; 95% confidence interval [CI], 1.1-5; P = 0.03; BAI: OR, 1.9; 95% CI, 1-3.8; P = 0.02), whereas BMI, DXA-trunk fat, and WHtR showed no correlation. Higher serum phosphorus and hyperparathyroidism were related (P < 0.05) to vitamin D deficiency. IR was not independently associated with 25-hydroxyvitamin D concentration. CONCLUSIONS: Just under half of the CKD population presented sufficient concentration of 25-hydroxyvitamin D. Total body adiposity, independent of age and eGFR, regardless if evaluated by DXA or BAI, was the predictor of vitamin D deficiency, which in turn was associated with higher serum phosphorus and hyperparathyroidism, but not with IR. PMID- 27692989 TI - Serum adiponectin and protein-energy wasting in predialysis chronic kidney disease. AB - OBJECTIVE: Adiponectin (ADPN) has antiatherogenic, anti-inflammatory, and insulin sensitizing effects. Serum ADPN levels are increased in patients with chronic kidney diseases (CKD), and higher ADPN is paradoxically a predictor of mortality in these patients. The aim of this study was to determine the association between serum ADPN levels and protein-energy wasting (PEW) in predialysis CKD. METHOD: We examined serum ADPN concentrations and PEW in 1303 patients from the KNOW-CKD (KoreaN Cohort Study for Outcome in Patients With Chronic Kidney Disease) study. PEW was defined as the presence of three or more of the following four indicators: serum albumin <3.8 g/dL, body mass index <23 kg/m2, urine creatinine excretion (UCE) below the lower quartile, and daily dietary protein intake <0.6 g/kg. We analyzed the association between PEW and ADPN using a multivariate regression model after adjustment for socioeconomic factors, comorbidities, and laboratory findings. RESULTS: Among 1303 predialysis CKD patients, 72 (5.5%) had PEW. In multivariate logistic regression analysis, higher ADPN level was associated with PEW (odds ratio, 1.04; 95% confidence interval [CI], 1.01-1.08 by 1 MUg/mL ADPN). The highest ADPN quartile was associated with PEW in comparison with the lowest quartile (odds ratio, 10.54; 95% CI, 1.28-86.74). In multiple linear regression with PEW indicators, ADPN was more strongly associated with UCE (beta = -2.21; 95% CI, -4.13 to -0.28; R2 = 0.67). CONCLUSION: High ADPN is independently associated with PEW. Among PEW indicators, serum ADPN is closely associated with UCE as an indirect measure of muscle mass. PMID- 27692991 TI - Chronic brain damage in sickle cell disease and its relation with quality of life. AB - BACKGROUND AND OBJECTIVE: Sickle cell anaemia causes progressive organ damage. The objective is to describe school performance of patients with sickle cell anaemia and their clinical parameters and quality of life that may have an influence. The hypothesis is that if school alterations occur without other objective data, additional factors must be present besides the disease itself. PATIENTS AND METHODS: Transversal study performed in November 2015 considering analytical variables, complications and neuroradiological images of children with sickle cell anaemia, and family survey on school performance and quality of life. RESULTS: Median age was 6.8 years and 78% were diagnosed at birth. Sixty patients were included. School performance was altered in 51% of cases and was related to nocturnal hypoxemia. Acute stroke incidence was 6.7%. Transcranial ultrasound was abnormal in 4% of cases and magnetic resonance imaging in 16% of cases. Quality of life showed pathological findings in all areas and the low values increased proportionally in older ages. The stroke affected the physical and social sphere, and lung disease affected the physical and emotional spheres. CONCLUSIONS: Poor school performance affects half of the patients and it is related to nocturnal hypoxemia, although other socio-cultural factors may have an influence. Quality of life is affected in most of these cases independently of academic results. The absence of alterations in neuroimaging or the apparent lack of severe clinical parameters do not mean that quality of life and schooling are normal. PMID- 27692992 TI - Neurobiology of Congenital Amusia. AB - The past decade of research has provided compelling evidence that musical engagement is a fundamental human trait, and its biological basis is increasingly scrutinized. In this endeavor, the detailed study of individuals who have musical deficiencies is instructive because of likely neurogenetic underpinnings. Such individuals have 'congenital amusia', an umbrella term for lifelong musical disabilities that cannot be attributed to intellectual disability, lack of exposure, or brain damage after birth. Key points are reviewed here that have emerged during recent years regarding the neurobiology of the disorder, focusing on the importance of recurrent processing between the right inferior frontal cortex and the auditory cortex for conscious monitoring of musical pitch, and how this relates to developmental cognitive disorders in general.

The growth disturbances in the skull and face being variable according to the type of mutation in the FGFr (Crouzon, Pfeiffer, Apert), the strategy is adapted to the phenotype according to the following principles: posterior expansion with or without distraction around 6 months to limit the descent of the cerebellum tonsils and to prevent the turricephalic development; fronto-facial monobloc advancement with internal distraction around the age of 18 months in case of severe exorbitism or breathing impairment. The dissociated strategy (fronto-orbital advancement first, followed by facial osteotomy of Le Fort 3 type). The growing evolution dictates the sequence of subsequent surgeries according to the monitoring of intracranial pressure by fundus examination and of the respiration by polysomnography. Le Fort 3 and transversal maxillary distraction may be repeated if necessary.

Among them, 6-6 bicyclic ring containing structures (e.g., isoflavone phytoestrogens) are regarded as one of the cyclized analogues of isobutestrol 5b, and suggest that other cyclized scaffolds comprising 5-6 bicyclic rings could also act as selective ERbeta ligands. In this study, we evaluated the selective ERbeta agonistic activity of 1 (4-hydroxybenzyl)indan-5-ol 7a and studied structure-activity relationship (SAR) of its derivatives. Some functional groups improved the properties of 7a; introduction of a nitrile group on the indane-1-position resulted in higher selectivity for ERbeta (12a), and further substitution with a fluoro or a methyl group to the pendant phenyl ring was also preferable (12b, d, and e). Subsequent chiral resolution of 12a identified that R-12a has a superior profile over S-12a. This is comparable to diarylpropionitrile (DPN) 5c, one of the promising selective ERbeta agonists and indicates that this indane-based scaffold has the potential to provide better ERbeta agonistic probes.

AB - The benzyloxy substituted small molecules are well-known highly potent monoamine oxidase B inhibitors, but their therapeutic potential against Parkinson's disease have not been investigated in detail. In this paper, a series of representative benzyloxy substituted derivatives were synthesized and evaluated for MAO-A/B inhibition. In addition, their neuroprotective effects were investigated in 6 OHDA- and rotenone-treated PC12 cells. It was observed that most of the compounds exhibited a marked increase in survival of PC12 cells which treated with the neurotoxins. Among them, 13 exhibited remarkable and balanced neuroprotective potency. The protective effects of 13 against neurotoxins-induced apoptosis were confirmed with flow cytometry and staining methods. Furthermore, 13 also showed good BBB permeability and low toxicity according to in vitro BBB prediction and in vivo acute toxicity test. The results indicated that 13 is an effective and promising candidate to be further developed as disease-modifying drug for Parkinson's disease therapy. PMID- 27692999 TI - [Functional treatment of children subcondylar fractures: An axiographic assessment]. AB - INTRODUCTION: Subcondylar fractures are common in children. Occlusion disorders resulting from these fractures in deciduous or mixed dentition do not have as much impact as in adults due to alveolar adaption possibilities. Functional treatment allows for good functional results, but does not treat the dynamic shortening of the ramus. The objective of this study was to evaluate the axiographic condylar slope changes after subcondylar fracture in children. MATERIALS AND METHODS: A prospective study was conducted from 2010 to 2015, including all the under-18 patients presenting with a subcondylar fracture. Examination by mean of a Quick Axis axiograph measured the length of propulsion and the condylar inclination on both sides. The main evaluation criterion was the amount of condylar inclination decrease on the fractured side. RESULTS: Twelve patients (mean age: 10.42; 5-16) were included. Eleven children had a loss of condylar inclination on the fractured side without occlusion disorders at 33.2 months on average (3-144 months) after the initial trauma. Only one patient had symmetric axiographies without loss of condylar inclination on the fractured side. DISCUSSION: Dynamic shortening of the ramus on the side of the subcondylar fracture is consistent at short and medium terms in children. Surgical treatment may be the solution for avoiding this dynamic disorder of the mandible and should be evaluated.

AB - Since data about Clostridium difficile infection in sub-Saharan Africa are scarce, we determined its epidemiology and risk factors in a cross-sectional study in Eikwe, a rural community in Ghana. We tested stool samples from 176 hospitalized patients with diarrhoea and from 131 asymptomatic non-hospitalized individuals for C. difficile and some other enteric pathogens. The overall prevalence rate of C. difficile was 4.9% with ribotype 084 being predominant. With 75% of the isolates, a high rate of nontoxigenic strains was present in symptomatic patients, most of whom had no other identified enteric pathogens. All strains were susceptible against metronidazole and vancomycin, respectively. Data on lifestyle and medical history showed that age <5years (p=0.004), and use of ceftriaxone (p=0.023) were the most important risk factors for C. difficile carriage status. Although our data suggest that C. difficile is currently not a major cause of diarrhoea in this setting, the epidemiology of C. difficile in sub Saharan Africa awaits further investigation. PMID- 27693001 TI - Accelerated Accumulation of Multimorbidity After Bilateral Oophorectomy: A Population-Based Cohort Study. AB - OBJECTIVE: To study the association between bilateral oophorectomy and the rate of accumulation of multimorbidity. PATIENTS AND METHODS: In this historical cohort study, the Rochester Epidemiology Project records-linkage system was used to identify all premenopausal women who underwent bilateral oophorectomy before age 50 years between January 1, 1988, and December 31, 2007, in Olmsted County, Minnesota. Each woman was randomly matched to a referent woman born in the same year (+/-1 year) who had not undergone bilateral oophorectomy. We studied the rate of accumulation of 18 common chronic conditions over a median of approximately 14 years of follow-up. RESULTS: Although women who underwent bilateral oophorectomy already had a higher multimorbidity burden at the time of oophorectomy, they also experienced an increased risk of subsequent multimorbidity. After adjustments for 18 chronic conditions present at baseline, race/ethnicity, education, body mass index, smoking, age at baseline, and calendar year at baseline, women who underwent oophorectomy before age 46 years experienced an increased risk of depression, hyperlipidemia, cardiac arrhythmias, coronary artery disease, arthritis, asthma, chronic obstructive pulmonary disease, and osteoporosis. In addition, they experienced an accelerated rate of accumulation of the 18 chronic conditions considered together (hazard ratio, 1.22; 95% CI, 1.14-1.31; P<.001). Several of these associations were reduced in women who received estrogen therapy. CONCLUSION: Bilateral oophorectomy is associated with a higher risk of multimorbidity, even after adjustment for conditions present at baseline and for several possible confounders. However, several of these associations were reduced in women who received estrogen therapy. PMID- 27693003 TI - Electronic cigarettes increase endothelial progenitor cells in the blood of healthy volunteers. AB - BACKGROUND AND AIMS: The use of electronic cigarettes is increasing dramatically on a global scale and its effects on human health remain uncertain. In the present study, we measured endothelial progenitor cells (EPCs) and microvesicles (MVs) in healthy young volunteers following short-term exposure to inhalation of e-cigarette vapor (ECV) to determine vascular changes. METHODS: Sixteen healthy seldom smokers were randomized into two groups either exposed or not exposed to 10 puffs of ECV for 10 min, in a crossover design. Blood samples were obtained at baseline and 1, 4 and 24 h following exposure. EPCs (CD34 + CD309) and MVs were analyzed by flow cytometry. MVs were phenotyped according to origin (platelet (CD41), endothelial (CD144), leukocytes (CD45), monocytes (CD14)) and nuclear content (SYTO 13 dye). In addition, expression of inflammation markers such P selectin (CD62P), E-selectin (CD62E), CD40-ligand (CD154) and HMGB1 was investigated. Fractional exhaled nitric oxide (FeNO) was also measured at baseline and after 24 h. RESULTS: EPC levels in blood were significantly increased 1 h following exposure to ECV and returned to baseline values after 24 h. Only E-selectin positive MVs (endothelial origin) were slightly elevated (p < 0.038). FeNO was unaffected by exposure to ECV. CONCLUSIONS: In healthy volunteers, ten puffs of e-cigarette vapor inhalation caused an increase in EPCs. This increase was of the same magnitude as following smoking of one traditional cigarette, as we previously demonstrated. Taken together, these results may represent signs of possible vascular changes after short e-cigarette inhalation. Further studies analyzing potential cardiovascular health effects are critical as the e-cigarette market continues to burgeon. PMID- 27693004 TI - Collective impact of conventional cardiovascular risk factors and coronary calcium score on clinical outcomes with or without statin therapy: The St Francis Heart Study. AB - BACKGROUND AND AIMS: The efficacy of statin therapy remains unknown in patients eligible for statin therapy with and without elevated coronary calcium score (CAC). The study sought to evaluate how cardiovascular risk factors, expressed in terms of statin eligibility for primary prevention, and CAC modify clinical outcomes with and without statin therapy. METHODS: We conducted a post-hoc analysis of the St. Francis Heart Study treatment trial, a double-blind, placebo controlled randomized controlled trial of atorvastatin (20 mg), vitamin C (1 g), and vitamin E (1000 U) daily, versus placebos in 990 asymptomatic individuals with CAC >= 80th percentile for age and gender. Primary cardiovascular outcomes included non-fatal myocardial infarction or coronary death, coronary revascularization, stroke, and peripheral arterial revascularization. We further stratified the treatment and placebo groups by eligibility (eligible when statin indicated) for statin therapy based on 2013 ACC/AHA guidelines and based on CAC categories. RESULTS: After a median follow-up of 4.8 years, cardiovascular events had occurred in 3.9% of the statin treated but not eligible, 4.6% of the untreated and not eligible, 8.9% of the treated and eligible and 13.4% of the untreated and eligible groups, respectively (p<0.001). Low CAC (<100) occurred infrequently in statin eligible subjects (<=4%) and was associated with low 10 year event rate (<1 per 100 person-years). In contrast, high CAC (>300) occurred frequently in more than 35% of the statin not eligible subjects and was associated with a high 10-year event rate (>=17 per 100 person-years). Risk prediction improved significantly when both clinical risk profile and CAC score were combined (net reclassification index p = 0.002). CONCLUSIONS: Under the current statin treatment guidelines a small number of statin eligible subjects with low CAC might not benefit from statin therapy within 5 years. However, the statin not eligible subjects with high CAC have high event rate attributing to loss of opportunity for effective primary prevention.

AB - Coronary artery disease and atherosclerosis are complex pathologies that develop over time due to genetic and environmental factors. Differential expression of miRNAs has been identified in patients with coronary artery disease and atherosclerosis, however, their association with cardiovascular disease risk factors, including hyperlipidemia, hypertension, obesity, diabetes, lack of physical activity and smoking, remains unclear. This review examines the role of miRNAs as either biomarkers or potential contributors to the pathophysiology of these aforementioned risk factors. It is intended to provide an overview of the published literature which describes alterations in miRNA levels in both human and animal studies of cardiovascular risk factors and when known, the possible mechanism by which these miRNAs may exert either beneficial or deleterious effects. The intent of this review is engage clinical, translational, and basic scientists to design future collaborative studies to further elucidate the potential role of miRNAs in cardiovascular diseases.

PMID- 27693007 TI - Paired comparison of the sensitivity and specificity of multispectral digital skin lesion analysis and reflectance confocal microscopy in the detection of melanoma in vivo: A cross-sectional study. AB - BACKGROUND: Several technologies have been developed to aid dermatologists in the detection of melanoma in vivo including dermoscopy, multispectral digital skin lesion analysis (MDSLA), and reflectance confocal microscopy (RCM). To our knowledge, there have been no studies directly comparing MDSLA and RCM. OBJECTIVE: We conducted a repeated measures analysis comparing the sensitivity and specificity of MDSLA and RCM in the detection of melanoma (n = 55 lesions from 36 patients). METHODS: Study patients (n = 36) with atypical-appearing pigmented lesions (n = 55) underwent imaging by both RCM and MDSLA. Lesions were biopsied and analyzed by histopathology. RESULTS: RCM exhibited superior test metrics (P = .001, McNemar test) compared with MDSLA. Respectively, sensitivity measures were 85.7% and 71.4%, and specificity rates were 66.7% and 25.0%. LIMITATIONS: The sample size was relatively small and was collected from only one dermatologist's patient base; there was some degree of dermatopathologist interobserver variability; and only one confocalist performed the RCM image evaluations. CONCLUSION: RCM is a useful adjunct during clinical assessment of in vivo lesions suspicious for melanoma or those requiring re-excision because of high level of dysplasia or having features consistent with an atypical melanocytic nevus with severe cytologic atypia. PMID- 27693008 TI - Risk of serious infections, cutaneous bacterial infections, and granulomatous infections in patients with psoriasis treated with anti-tumor necrosis factor agents versus classic therapies: Prospective meta-analysis of Psonet registries. AB - BACKGROUND: Anti-tumor necrosis factor (TNF) therapy in psoriasis has been associated with an increased risk of serious infections compared with nonbiologic systemic therapies. OBJECTIVE: We sought to quantify the risk of: (1) serious infections (leading to hospitalization, sequelae, or death); and (2) "any infection," bacterial cutaneous infections, and granulomatous infections among patients receiving anti-TNF therapy compared with nonbiologics (acitretin, methotrexate, cyclosporine). METHODS: We used prospective meta-analysis to combine data from the Psocare registry (Italy), Biobadaderm registry (Spain), and Clalit Health Services database (Israel), including 17,739 patients and 23,357.5 person-years of follow-up. RESULTS: For serious infections, age, gender, and Charlson morbidity index adjusted hazard ratio of exposure to anti-TNFs compared with nonbiologics was 0.98 (95% confidence interval 0.80-1.19), for bacterial cutaneous infections it was 1.00 (95% confidence interval 0.62-1.61), and for granulomatous infections it was 1.23 (95% confidence interval 0.82-1.84). Using methotrexate as comparator and comparing first year of exposure with later exposure did not modify the results. For any infectious episode, risks and relative risks were heterogeneous among registries, probably because of different definitions of outcome. LIMITATIONS: There was lack of power to describe risk of single drugs. CONCLUSION: In current clinical practice, treatment with anti-TNF drugs was not associated with a higher risk of serious infections than treatment with nonbiologic systemic therapy. PMID- 27693009 TI - Mugil curema as a PAH bioavailability monitor for Atlantic west sub-tropical estuaries. AB - This work aimed to evaluate the use of Mugil curema as a biomonitor for polycyclic aromatic hydrocarbon (PAH) bioavailability. Fish biliary metabolites from low-contaminated (Cananeia) and contaminated (Santos) Brazilian estuaries were analysed using a high-performance liquid chromatography apparatus coupled to fluorescence detectors connected in a series. In the Cananeia and Santos estuaries, total metabolite levels ranged from 0.85 to 34.4MUgg-1 of bile and from 4.06 to 528MUgg-1 of bile, respectively. Metabolite levels were not influenced by feeding status or sexual hormones (p<0.05), thus suggesting that M. curema is a good biomonitor for PAH bioavailability. In estuarine regions, it is possible to sample both the male and female genders of this species in any reproductive period. PMID- 27693010 TI - Effect of probiotics on respiratory, gastrointestinal and nutritional outcomes in patients with cystic fibrosis: A systematic review. AB - BACKGROUND: An increasing body of research investigating the use of probiotics to improve health outcomes in patients with cystic fibrosis (CF) prompted the need to systematically assess and summarise the relevant literature. METHODS: An electronic search of five databases and three trial databases was conducted. Studies describing the administration of probiotics to patients with CF older than 2years, with a comparator group on respiratory, gastrointestinal and nutritional outcomes were included. RESULTS: Three pre-post studies and six randomised controlled trials met the inclusion criteria. Overall studies showed a positive effect of probiotics on reducing the number of pulmonary exacerbations and decreasing gastrointestinal inflammation. There was limited effect of probiotics on other outcomes and inadequate evidence for the effects of specific probiotic species and strains. CONCLUSION: The findings suggest that probiotics may improve respiratory and gastrointestinal outcomes in a stable CF clinic population with no reported evidence of harm. There is inadequate evidence at this time to recommend a specific species, strain or dose of probiotic as likely to be of significant benefit. PMID- 27693011 TI - The nitric oxide serum level and combined utero-placental thickness in buffalo (Bubalus bubalis) affected by pregnancy pathology. AB - The present study aimed mainly to study the level of nitric oxide (NO) and combined thickness of the uterus and placenta (CTUP) in buffaloes affected by pregnancy pathology. Females (n = 104) were classified into three main groups: nonpregnant (n = 10), healthy pregnant (n = 54), and pathologically pregnant (n = 40). The healthy pregnant animals were subgrouped according to the stage of pregnancy to early stage (n = 15), mid stage (n = 15), late stage (n = 19), and full term (n = 5). The animals in which pregnancy was associated with placental pathology were subgrouped to uterine torsion (n = 27), hydroallantois (n = 5), and abortion (n = 8). Blood samples were collected from all animals to estimate the NO level using Griess reaction test. Combined thickness of the uterus and placenta was measured at the most caudal part of the pregnant horn using a rectal ultrasound probe. Placental tissue samples were collected from all pregnant animals just after delivery or abortion for histopathologic section. The results revealed that the level of NO was higher (P <= 0.05) in pregnant than in nonpregnant animals (6.89 +/- 0.18 MUM). Additionally, NO level was decreased significantly at full term (18.26 +/- 0.27 MUM) when compared to the other stages of pregnancy. Moreover, there was a decrease (P <= 0.05) in the level of NO in cases of uterine torsion (22.22 +/- 0.46 MUM) and hydroallantois (24.20 +/- 0.07 MUM) in comparison with the normal pregnant buffalo. The CTUP was significantly increased as pregnancy progressed. The CTUP in cases of uterine torsion (18.2 +/- 3.3 mm) was higher (P < 0.05) than in healthy pregnant buffalo at the same stage of pregnancy. Additionally, CTUP significantly differed between different types of uterine torsion. There was no significant difference between CTUP in hydroallantois and abortion cases besides healthy pregnancy. Histopathologic examination revealed a great proliferation and hyperplasia of cytotrophoblastic cells only in uterine torsion and hydroallantois cases. In conclusion, NO level and CTUP can be used as indicators for pregnancy pathology that is usually associated with presence of cytotrophoblastic cells and placental insufficiency. PMID- 27693012 TI - Anti-Muellerian hormone, inhibin A, gonadotropins, and gonadotropin receptors in bull calves after partial scrotal resection, orchidectomy, and Burdizzo castration. AB - Eight-week-old calves were either castrated by partial scrotal resection (SR) without removing the testes (n = 10), Burdizzo (BZ) clamp (n = 10), orchidectomy (OR; n = 10), or were left gonad intact as controls (CO; n = 10). Concentrations of anti-Muellerian hormone (AMH), inhibin A, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) in plasma were determined from 16 to 48 weeks of age. At 18 months, testes of SR, BZ, and CO bulls were obtained and the immunolocalization of LH and FSH receptors and AMH analyzed. Concentration of AMH in plasma of CO and SR bulls decreased with increasing age (P < 0.001). A similar AMH profile in CO and SR indicates that SR did not induce a true cryptorchid state. In groups OR and BZ, AMH was undetectable. Plasma inhibin concentration was higher in groups CO and SR than BZ and OR (P < 0.001). Plasma LH and FSH concentrations decreased over time (P < 0.001) and were higher in groups BZ and OR than SR and CO (P < 0.001). In the testes, immunolabeling for AMH existed in Sertoli cells of CO and SR but not BZ bulls. FSH receptors were localized in Sertoli cells, Leydig cells, spermatocytes, and the epididymis of CO and SR animals, whereas LH receptors were restricted to Leydig cells. In BZ animals, FSH and LH receptors and AMH were absent, indicating complete testicular degeneration. In conclusion, AMH is a more reliable marker for the presence of testicular tissue in bulls than inhibin. Scrotal resection did not induce a true inguinal cryptorchid state but affected testicular responsiveness to gonadotropic stimulation. PMID- 27693013 TI - Proposed breakpoint of piperacillin/tazobactam against extended spectrum beta lactamases producing bacteria in bacteremia. AB - The isolation rate of extended-spectrum beta-lactamase (ESBL)-producing bacteria have been increasing in Japan. While the efficacy of piperacillin/tazobactam (PIPC/TAZ) for ESBL-producing bacteria is controversial, carbapenems have generally been shown to be effective. The aim of this study was to determine whether the current Clinical and Laboratory Standards Institute susceptibility breakpoint of <=16/4 MUg/mL PIPC/TAZ predicts the clinical usefulness for bacteremia caused by ESBL-producing Enterobacteriaceae. We retrospectively investigated 35 patients with bacteremia caused by Enterobacteriaceae producing ESBLs treated with PIPC/TAZ monotherapy. The microbiological and clinical efficacy with PIPC/TAZ minimum inhibitory concentrations (MICs) of <=16/4 MUg/mL was better than that with MICs >= 32/4 MUg/mL. In contrast, MICs <=8/4 MUg/mL showed significantly higher microbiological and clinical efficacy compared to that of MICs >=16/4 MUg/mL (P < 0.05). These results suggest that 8/4 MUg/mL PIPC/TAZ MIC is recommended as a breakpoint for bacteremia caused by ESBL producing Enterobacteriaceae in Japan, although the current CLSI breakpoint is also useful. PMID- 27693014 TI - Effectiveness of weekly polymerase chain reaction-based open reading frame typing analysis of all newly isolated methicillin-resistant Staphylococcus aureus strains for controlling nosocomial infections. AB - Polymerase chain reaction (PCR)-based open reading frame typing (POT) helps differentiate between bacterial strains based on the open reading frames (ORFs) of the prophage-encoding genes; multiplex PCR screening is performed to identify strains based on keeping patterns. At our hospital, surveillance of nosocomial methicillin-resistant Staphylococcus aureus (MRSA) transmission is undertaken using POT to conduct molecular epidemiological analysis for all newly detected MRSA strains. In 2014, we performed POT only once a month; however, in 2015, we increased the frequency of POT to once a week, which helped us detect nosocomial transmission that would normally be difficult to detect, and thus achieve 40% reduction in nosocomial transmission, compared to that in 2014. This suggests that weekly POT screening for all MRSA strains is one of the effective methods available for minimizing nosocomial transmission of MRSA. PMID- 27693015 TI - Silver bonded to silica gel applied to the separation of polycyclic aromatic sulfur heterocycles in heavy gas oil. AB - Silica gel containing silver ions was prepared and characterized. Silica was organofunctionalized with 3-mercaptopropyl group by using grafting reaction followed by silver ions adsorption (silver covalently bonded to mercaptopropyl silca gel, Ag-MPSG). The organofunctionalization and silver coordination were observed by transmission infrared spectroscopy and elemental analyses (CHN and EDS). The textural characteristics were studied by N2 adsorption-desorption isotherms. Additionally, optical properties were studied by diffuse reflectance spectroscopy. The Ag-MPSG material was employed as stationary phase for the first time for fractionation of a heavy gas oil sample resulting in a fraction that is richer in polycyclic aromatic sulfur heterocycles (PASH). The fractions were analyzed by comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometric detector and Ag-MPSG material provided similar fractionation performance when compared to conventional material [palladium covalently bonded to mercaptopropyl silca gel, Pd(II)-MPSG] usually employed for the same purpose and as the cost of silver is less than the one of palladium, the cost of the fractionation phase was reduced. PMID- 27693016 TI - Graphene oxide framework: An adsorbent for solid phase extraction of phenylurea herbicides from water and celery samples. AB - 1,4-Phenyldiboronic acid (1,4-PDBA) linked graphene oxide framework (GOF) was prepared via an one-step, catalyst-free and hydrothermal route. To evaluate its adsorption performance, the prepared GOF was served as an adsorbent for solid phase extraction of phenylurea herbicides (PUHs) from water and celery samples prior to their determination by high performance liquid chromatography. The results indicated that GOF exhibited excellent adsorption capacity for the target PUHs. Under the optimum conditions, the method showed high recoveries ranged from 86.0% to 112.0%, low relative standard deviations (<5.4%) and low limits of detection ranged from 0.01 to 0.02ngmL-1 for water and 0.025-0.050ngg-1 for celery sample, respectively. These results indicated the great application potential of GOF in the enrichment of organic pollutants from different matrix samples. PMID- 27693017 TI - Standardized bovine colostrum derivative impedes development of type 1 diabetes in rodents. AB - Bovine colostrum is a rich source of nutrients and immunologically active components that play a role in conveying passive immunity to the offspring, protection and maturation of new-born's gastrointestinal tract. Colostrum has exerted positive effects in diseases affecting gastrointestinal tract, as well as type 2 diabetes (T2D). However, health-promoting effects in type 1 diabetes have not been reported. The aim of this study was to investigate therapeutic value of oral administration of standardized bovine colostrum derivative (SBCD) in three models of type 1 diabetes (T1D): spontaneously developed T1D in NOD mice and BB DP rats, and in chemically induced T1D in C57BL/6 mice with multiple low doses of streptozotocin (MLDS). SBCD was administered per os and the disease development was evaluated by weekly measurement of blood glucose and by histological analyses of the pancreas. SBCD administration prevented diabetes development in all three models, as indicated by euglicaemia. Ex vivo analysis of cytokine expression and production in the spleen and mesenteric lymph nodes (MLN) in MLDS challenged mice revealed a strong modulation of the immune response. In the MLN cells SBCD disrupted harmful Th17 response induced by MLDS. Expression of Th1 signature cytokine IFN-gamma was down-regulated in MLN cells of SBCD-treated mice, while IL 4 secretion (Th2 cytokine) was up-regulated in comparison to diabetic group. Modulation of the immune response seen in the MLN protruded to the spleen, giving overall less infiltration of immune cells to the pancreas. SBCD acted on immune cells and halted (auto) aggression towards pancreatic beta cells. Moreover, SBCD induced beta cell proliferation. Hence, this derivative could be tested in diabetes and other similar diseases with aberrant immune response. PMID- 27693018 TI - A vaccine composed of a hypothetical protein and the eukaryotic initiation factor 5a from Leishmania braziliensis cross-protection against Leishmania amazonensis infection. AB - In the present study, two proteins cloned from Leishmania braziliensis species, a hypothetical protein (LbHyp) and the eukaryotic initiation factor 5a (EiF5a), were evaluated to protect BALB/c mice against L. amazonensis infection. The animals were immunized with the antigens, either separately or in combination, using saponin as an immune adjuvant in both cases. Spleen cells from vaccinated and later infected mice produced significantly higher levels of protein and parasite-specific IFN-gamma, IL-12, and GM-CSF, in addition to low levels of IL-4 and IL-10. Evaluating the parasite load by means of a limiting dilution technique and quantitative Real-Time PCR, vaccinated animals presented significant reductions in the parasite load in both infected tissues and organs, as well as lower footpad swelling, when compared to the control (saline and saponin) groups. The best results regarding the protection of the animals were achieved when the combined vaccine was administered into the animals. Protection was associated with an IFN-gamma production against parasite antigens, which was mediated by both CD4+ and CD8+ T cells and correlated with antileishmanial nitrite production. In conclusion, data from the present study show that this polyprotein vaccine, which combines two L. braziliensis proteins, can induce protection against L. amazonensis infection. PMID- 27693019 TI - Enzyme-linked immunosorbent assays for detection of anti-transcriptional intermediary factor-1 gamma and anti-Mi-2 autoantibodies in dermatomyositis. AB - BACKGROUND: Autoantibodies against transcriptional intermediary factor 1 (TIF1) and Mi-2 are selectively detected in patients with dermatomyositis (DM). To measure these antibodies readily, the development of reliable ELISA systems has been needed. OBJECTIVE: This study aimed to establish enzyme-linked immunosorbent assays (ELISAs) for anti-TIF1gamma and anti-Mi-2beta antibodies (Abs) and to assess their utility. METHODS: Serum samples were obtained from 104 patients with classic DM, 68 with clinically amyopathic DM (CADM) and 70 with polymyositis, who were followed up at 8 medical centers across Japan. Serum samples from 190 patients with other connective tissue diseases (CTDs) and 123 healthy individuals were also assessed. Serum antibody levels were examined by ELISAs coated with full-length TIF1gamma or Mi-2beta proteins produced by a baculovirus expression system. To assess the cross-reactivity, partial-length Mi-2beta proteins with or without mutations were produced and examined for reactivity. RESULTS: When compared with immunoprecipitation assay, anti-TIF1gamma Ab ELISA showed 100% sensitivity and 100% specificity, while anti-Mi-2beta Ab ELISA showed 100% sensitivity and 99.6% specificity. Anti-TIF1gamma Ab was positive in 30 (28.8%) with classic DM and 4 (5.9%) with CADM, whereas 14 (13.5%) with classic DM, but none with CADM, were positive for anti-Mi-2beta Ab. Of 30 anti-TIF1gamma Ab positive DM patients, 23 (67.6%) had malignancy. Anti-Mi-2beta Ab-positive serum samples exhibited modest cross-reactivity with the TIF1gamma protein due to the homologous amino acid sequence containing cysteines in their plant homeodomains. CONCLUSION: The current study demonstrates the utility of newly established ELISAs for anti-TIF1gamma and anti-Mi-2beta Abs, which can serve as easier detection systems for routine testing. PMID- 27693020 TI - Novel lipopeptides of ESAT-6 induce strong protective immunity against Mycobacterium tuberculosis: Routes of immunization and TLR agonists critically impact vaccine's efficacy. AB - Mycobacterium tuberculosis (Mtb), the bacterial cause of tuberculosis, is a leading infectious agent worldwide. The development of a new vaccine against Mtb is essential to control global spread of tuberculosis, since the current vaccine BCG is not very effective and antibiotic resistance is a serious, burgeoning problem. ESAT-6 is a secreted protein of Mtb, which is absent in BCG but has been implicated in inducing protective immunity against Mtb. Peptide based subunit vaccines are attractive due to their safety and high specificity in eliciting immune responses, but small synthetic peptides are usually not very immunogenic. We have designed a novel subunit vaccine for Mtb by using simple lipid (palmitic acid) modified derivatives of peptides from ESAT-6 protein corresponding to dominant human T cell epitopes and examined their ability to stimulate protective immunity against Mtb by intranasal and subcutaneous immunization in mice. We also investigated how individual TLR agonists as adjuvants (PolyI:C, MPL and GDQ) contribute to enhancing the induced immune responses and resulting protective efficacy of our vaccine. We observed that single C-terminal palmitoyl-lysine modified lipopeptides derived from ESAT-6 induce significant cellular immune responses on their own upon mucosal and subcutaneous immunizations. Intriguingly, a combination of immunogenic lipopeptides of ESAT-6 antigen exhibited local (pulmonary) and systemic immune responses along with efficient protective efficacy when administered intranasally or subcutaneously. Surprisingly, combination of ESAT-6 derived lipopeptides with a TLR-4 agonist (MPL) enhanced protection, whereas TLR-3 (Poly I:C) and TLR-7/8 agonists (gardiquimod, GDQ) led to reduced protection associated with specific local and systemic immune modulation. Our studies demonstrate the potential of ESAT-6 derived lipopeptides as a promising vaccine candidate against Mtb, and emphasize that selection of adjuvant is critical for the success of vaccines. These findings demonstrate the promise of synthetic lipopeptides as the basis of a subunit vaccine for TB.

AB - PURPOSE: We report the clinical outcome after coverage for soft-tissue defect on the medial foot and ankle with an adipofascial fold-down flap based on the posterior tibial artery perforator branch proximal to the defect. MATERIALS: Nine patients (five males and four females) with soft-tissue defects on the medial foot and ankle area underwent the procedure from March 2009 to May 2014. The average age of the patients was 54 years (range, 8-82). The pivot point of transposition of this flap is the posterior tibial artery perforator proximal to the defect. Therefore, the adiposal side of this flap was folded down to resurface the defect. The donor site was closed primarily with the preserved skin flap. The skin graft to the flap was delayed until the flap became mature. The difference between the circumferences of both ankles was measured. RESULTS: All flaps survived and adequate soft-tissue coverage was obtained for the medial foot and ankle after the skin graft. Wearing normal footwear was possible for all patients because of thin coverage of the flaps. No secondary debulking procedure was performed for the patients. The difference between the circumferences of both sides of the ankle was not significant. The skin necrosis of the donor site was also managed conservatively and healed well. CONCLUSION: For the medial foot and ankle soft-tissue defect, the fold-down adipofascial flaps based on the posterior tibial artery perforator branch proximal to the defect could be a good option to cover it.

AB - To understand organ function, it is important to have an inventory of its cell types and of their corresponding marker genes. This is a particularly challenging task for human tissues like the pancreas, because reliable markers are limited. Hence, transcriptome-wide studies are typically done on pooled islets of Langerhans, obscuring contributions from rare cell types and of potential subpopulations. To overcome this challenge, we developed an automated platform that uses FACS, robotics, and the CEL-Seq2 protocol to obtain the transcriptomes of thousands of single pancreatic cells from deceased organ donors, allowing in silico purification of all main pancreatic cell types. We identify cell type specific transcription factors and a subpopulation of REG3A-positive acinar cells. We also show that CD24 and TM4SF4 expression can be used to sort live alpha and beta cells with high purity. This resource will be useful for developing a deeper understanding of pancreatic biology and pathophysiology of diabetes mellitus. PMID- 27693028 TI - Discussion. PMID- 27693026 TI - Hemoptysis in a Patient with Elevated Immunoglobulin E. AB - Recurrent pneumonia with cavitation leading to pneumatoceles, secondary fungal infections, and hemoptysis are major causes of mortality and morbidity in patients with hyper-IgE syndrome. Prevention and aggressive treatment of pneumonia in these patients are essential to prevent further lung damage, but treatment may be delayed because the classic signs/symptoms of infection such as fever, chills, or rigors may be lacking. Early imaging to identify infection is essential for diagnosis and treatment. The mainstay of therapy is continuous, full-dose daily trimethoprim-sulfamethoxazole and commonly fungal coverage. Because hyper-IgE syndrome is a progressive disease, patients' condition may worsen despite compliance with prophylactic therapy. PMID- 27693029 TI - Iliofemoral endarterectomy associated with systematic iliac stent grafting for the treatment of severe iliofemoral occlusive disease. AB - OBJECTIVE: Iliofemoral endarterectomy with external iliac artery (EIA) stent grafting can be an alternative to traditional open surgery in patients with severe iliac occlusive disease extending to the common femoral artery. We report the midterm outcomes of this approach. METHODS: Between 2009 and 2015, 108 patients (76% male; median age, 63 years) underwent a total of 127 iliofemoral endarterectomies combined with EIA stent grafting. Indications were claudication in 60%, rest pain in 20%, ulceration in 15%, and acute ischemia in 5%. Lesions exclusively involved only the EIA segment in 40% of cases, with occlusion in 28%. Lesions involved both the EIA and common iliac artery segments in 49% of cases, with 19% of common iliac artery occlusions and 24% of EIA occlusions. Iliac lesions extended into the aortic segment in 11% of cases. Iliofemoral endarterectomy was performed by eversion whenever possible. Deployment of the EIA stent graft systematically incorporated the EIA segment and the proximal end of the endarterectomy. Self-expanding covered stents were calibrated to the diameter of the endarterectomized EIA. RESULTS: The procedure was technically successful in 100% of patients. Median diameter of covered stents was 8 mm (range, 6-10 mm). No intraoperative arterial rupture or dissection was observed. Early reoperations (3%) were performed for bleeding, infection, or thrombosis. Median length of stay was 5 days. No 30-day mortality was observed. Median follow-up was 30 months (range, 0-6 years), and overall mortality was 13% (due to cancer in half of the cases). Repeated angioplasty was performed in three (2%) cases, and a subsequent open procedure on the iliofemoral segment was performed in seven (5%) cases. At 2 years, primary patency rate of the treated segment was 91%. The 2-year primary assisted patency and secondary patency rates were 94% and 98%, respectively. Five year primary, primary assisted, and secondary patency rates were 87%, 92%, and 98%, respectively. CONCLUSIONS: Combined iliofemoral endarterectomy and covered stenting of the EIA for treatment of severe occlusive lesions provided acceptable midterm results, probably because of the gain of diameter provided by covered stents. This technique avoids complications due to an aortic or iliac surgical approach and clamping as well as complications related to the presence of a prosthetic implant in an intra-abdominal position. PMID- 27693027 TI - Diagnostic performance of 320-slice computed tomography coronary angiography for symptomatic patients in clinical practice. AB - OBJECTIVE: Multi-slice computed tomography (MSCT) coronary angiography has been reported as an effective alternative to invasive conventional coronary angiography (CCA) for the diagnosis of coronary artery disease (CAD). However, in previous reports, the diagnostic accuracy of MSCT has not been significant enough to be of benefit in symptomatic patients. The aim of this study was to identify the usefulness of 320-slice computed tomography coronary angiography (320-CTA) for symptomatic patients in terms of the diagnostic accuracy of 320-CTA and the prevalence of vasospastic angina pectoris (VSAP) within the study cohort. METHODS: We retrospectively analyzed 513 consecutive symptomatic patients with suspected CAD who had undergone 320-CTA and CCA. We determined the diagnostic accuracy of 320-CTA using CCA as the reference standard. Ergonovine provocation tests were performed on patients without significant coronary artery stenosis on CCA. RESULTS: Of the total cohort of 513 symptomatic patients, 39% had obstructive CAD. The patient based analysis of the accuracy of 320-CTA showed a sensitivity of 91.0%, a specificity of 71.0%, a positive predictive value of 66.5%, and a negative predictive value of 92.5%. Of the 314 symptomatic patients who did not have significant coronary artery stenosis on CCA, 58 (18%) were diagnosed with VSAP using ergonovine provocation tests. DISCUSSION: The negative and positive predictive values indicate that 320-CTA cannot replace CCA for symptomatic patients. Indeed, a combination of CCA and ergonovine provocation tests should be taken into consideration for symptomatic patients. PMID- 27693030 TI - Shear accumulation as a means for evaluating risk of thromboembolic events in novel endovascular stent graft designs. AB - OBJECTIVE: This study proposes to establish a simulation-based technique for evaluating shear accumulation in stent grafts and to use the technique to assess the performance of a novel branched stent graft system. METHODS: Computational fluid dynamics models, with transient boundary conditions, particle injection, and rigid walls, simplifying assumptions were developed and used to evaluate the shear accumulation in various stent graft configurations with a healthy aorta as comparison. RESULTS: Shear streamlines are presented for the various configurations. Shear accumulation was also calculated for each configuration. The number of particles with shear accumulations >3.5 Pa-s for each configuration was compared with the shear accumulation values of commercially available mechanical aortic valves from the literature. CONCLUSIONS: The stent graft configuration with the diaphragm does have particles with shear accumulation >3.5 Pa-s. However, the percentage of particles with shear accumulation above 3.5 Pa-s is less than the two commercially available mechanical aortic valves, and more surprisingly, is smaller than in the healthy aorta. PMID- 27693031 TI - Initial in vitro and in vivo evaluation of a self-monitoring prosthetic bypass graft. AB - OBJECTIVE: Prosthetic grafts used for lower extremity revascularization and dialysis access fail because of hyperplastic stenosis and thrombosis. Graft surveillance is advocated to monitor function; however, graft failure can occur between episodic examinations. An innovative sensor with wireless, microchip technology allows automated surveillance with assessment of graft function using a "cloud"-based algorithm. We performed proof-of-concept experiments with in vitro and in vivo models to assess the feasibility such a real-time graft surveillance system. METHODS: A self-monitoring graft system was evaluated consisting of a prosthetic conduit of expanded polytetrafluoroethylene and a sensor unit, and a microsensor, microelectronics, battery, and remote processor with a monitor. The sensor unit was integrated on the extraluminal surface of expanded polytetrafluoroethylene grafts without compromise to the lumen of the conduit. The grafts were tested in vitro in a pulsatile, recirculating flow system under physiologic flow parameters. The hemodynamic parameters were varied to assess the ability to obtain wireless signal acquisition reflecting real-time flow properties in vitro. Segments of custom tubing with reduced diameters were inserted into the model to mimic stenosis proximal and distal to the grafts. After characterization of the initial data, the self-monitoring grafts were implanted in an ovine carotid model to assess proof of concept in vivo with 30 day follow-up of signal acquisition as well as arteriographic and histologic analysis. RESULTS: In vitro flow data demonstrated the device was able to determine factors related to prosthetic graft function under varied hemodynamic flow conditions. Wireless signal acquisition using Bluetooth technology (Bluetooth SIG, Inc, Kirkland, Wash) allowed remote data analysis reflecting graft flow parameters through changes in microsensor voltage and frequency. Waveform analysis was applied to construct an algorithm using proprietary software and determine a parameter for graft flow characteristics. This algorithm allowed determination of the degree of stenosis and location of stenosis location (proximal or distal) for display on a remote monitor in real time. Subsequent in vivo experiments confirmed the ability of the system to generate signal acquisition through skin and soft tissue under biologic conditions with no arteriographic stenosis and a favorable healing response at 30-day harvest. CONCLUSIONS: Initial in vitro and in vivo experiments demonstrate the ability for a self-monitoring graft system to remotely monitor hemodynamic parameters reflecting graft function using wireless data transmission. This automated system shows promise to deliver real-time data that can be analyzed by cloud-based algorithms alerting the clinician of a change in graft function or development of stenosis for further diagnostic study or intervention before graft failure. PMID- 27693034 TI - A systematic review of concept mapping dissertations. AB - The purpose of this study was to identify, summarize, and synthesize all doctoral dissertations completed using Trochim's concept mapping methodology between 1985 and 2014. A comprehensive search produced a set of 108 eligible dissertations; of which 104 were available as full-text or hard copy. The studies were coded on 77 variables, which were summarized in descriptive analyses. The dissertations were conducted in a wide variety of topic areas and completed at 35 different universities in the US and Canada. On comparable variables, the results were similar to two prior syntheses (Trochim, 1993; Rosas & Kane, 2012). The mean multidimensional scaling analysis stress value for 96 concept maps was 0.26 with a standard deviation of 0.05. Cumulative rates of dissertation completion and resulting citations of the dissertations and any resulting articles were plotted over the study period. Reliability and validity were considered in most studies but formally assessed in a minority of cases. The review concludes with a summary of findings and thoughts about future studies. PMID- 27693032 TI - An endovascular model of ischemic myopathy from peripheral arterial disease. AB - OBJECTIVE: Peripheral arterial disease (PAD) is a significant age-related medical condition with limited pharmacologic options. Severe PAD, termed critical limb ischemia, can lead to amputation. Skeletal muscle is the end organ most affected by PAD, leading to ischemic myopathy and debility of the patient. Currently, there are not any therapeutics to treat ischemic myopathy, and proposed biologic agents have not been optimized owing to a lack of preclinical models of PAD. Because a large animal model of ischemic myopathy may be useful in defining the optimal dosing and delivery regimens, the objective was to create and to characterize a swine model of ischemic myopathy that mimics patients with severe PAD. METHODS: Yorkshire swine (N = 8) underwent acute right hindlimb ischemia by endovascular occlusion of the external iliac artery. The effect of ischemia on limb function, perfusion, and degree of ischemic myopathy was quantified by weekly gait analysis, arteriography, hindlimb blood pressures, femoral artery duplex ultrasound scans, and histologic examination. Animals were terminated at 5 (n = 5) and 6 (n = 3) weeks postoperatively. Ossabaw swine (N = 8) fed a high-fat diet were used as a model of metabolic syndrome for comparison of arteriogenic recovery and validation of ischemic myopathy. RESULTS: There was persistent ischemia in the right hindlimb, and occlusion pressures were significantly depressed compared with the untreated left hindlimb out to 6 weeks (systolic blood pressure, 31 +/- 21 vs 83 +/- 15 mm Hg, respectively; P = .0007). The blood pressure reduction resulted in a significant increase of ischemic myopathy in the gastrocnemius muscle in the treated limb. Gait analysis revealed a functional deficit of the right hindlimb immediately after occlusion that improved rapidly during the first 2 weeks. Peak systolic velocity values in the right common femoral artery were severely diminished throughout the entire study (P < .001), and the hemodynamic environment after occlusion was characterized by low and oscillatory wall shear stress. Finally, the internal iliac artery on the side of the ischemic limb underwent significant arteriogenic remodeling (1.8* baseline) in the Yorkshire but not in the Ossabaw swine model. CONCLUSIONS: This model uses endovascular technology to produce the first durable large animal model of ischemic myopathy. Acutely (first 2 weeks), this model is associated with impaired gait but no tissue loss. Chronically (2-6 weeks), this model delivers persistent ischemia, resulting in ischemic myopathy similar to that seen in PAD patients. This model may be of use for testing novel therapeutics including biologic therapies for promoting neovascularization and arteriogenesis. PMID- 27693033 TI - [Potentially inappropriate prescribing in older Spanish population according to STOPP/START criteria (STARTREC study)]. AB - OBJECTIVE: Rational prescribing in older people is a priority for health care organizations. The STOPP/START screening tool has been developed to identify potentially inappropriate prescribing (PIP) in individuals. In a primary care setting, STOPP/START can estimate PIP prevalence and related factors at population level. The aim of this study is to measure the prevalence rates of PPI in elderly population using clinical and prescription claim databases. DESIGN: Cross-sectional population study. SETTINGS: Primary Care, Lleida Health Region, Spain. PARTICIPANTS: 45.408 patients 70 years old and over, attended in the primary health care centers at least once the last year. METHODS: 43 STOPP and 12 START criteria are applied to their 2012 clinical and prescription records. Logistic regression models are adjusted to determine PIP association with several factors. RESULTS: 45,408 patients are included. The mean age is 79.7 years, 58% being female. The overall prevalence of PPI is 58.1%. According to STOPP, the most common drugs identified are benzodiazepines, non-steroidal anti-inflammatory drugs and proton pump inhibitors; according to START, osteoporosis treatments, antiplatelet agents, statins, metformin and beta blockers. PIP increases with age and polypharmacy and it is higher in long-term care facilities residents and patients receiving home health care. CONCLUSIONS: In our Health Region, at least 50% of the population aged 70 or older has one or more PIP, according to STOPP/START criteria.

AB - H19, one of the first found cancer-associated long non-coding RNAs (lncRNAs), is involved in the development and progression of many types of tumors. An aberrant expression of H19 was observed in hepatocellular carcinoma, cervical cancer, breast cancer, ovarian cancer, and colorectal cancer. However, the exact effects and molecular mechanisms of H19 in glioma progression are still unknown up to now. In this study, we investigated the role of H19 in human glioma cell lines and clinical tumor samples in order to determine the function of this molecule. In our research, lncRNA-H19 was specifically upregulated in glioma cell lines and promoted glioma cell growth through targeting miR-140. Knockdown of H19 inhibited the proliferation and invasion of human glioma cell and suppressed its metastasis in vitro and in vivo. In addition, miR-140 dependent inhibitor of apoptosis stimulating protein of p53 (iASPP) regulation was required in H19 induced glioma cell growth. These findings indicated that H19 might regulate the tumor growth and metastasis via miR-140 dependent iASPP regulation. Taken together, our data indicated that H19 might be an oncogenic lncRNA that promoted proliferation and metastasis of glioma and could be regarded as a therapeutic target in human glioma. PMID- 27693038 TI - High-fat diet feeding promotes stemness and precancerous changes in murine gastric mucosa mediated by leptin receptor signaling pathway. AB - Obesity increases the risk for gastric cancers. However, the occurrence and mechanisms of precancerous atrophic gastritis induced by high-fat diet (HFD) remain unclear. Here, we show that HFD-associated lipotoxicity induces precancerous lesions that are accompanied by the disruption of organelle homeostasis, tissue integrity, and deregulated expression of stemness genes in the gastric epithelium mediated by leptin receptor (ObR) signaling. Following HFD feeding, ectopic fat accumulated and expression of LAMP2A in lysosome and COX IV in mitochondria increased in the gastric mucosa. HFD feeding also led to enhanced expression of activated-Notch1 and stem cell markers Lgr5, CD44, and EpCAM. In addition, HFD-fed mice showed intracellular beta-catenin accumulation in the gastric mucosa with increased expression of its target genes, Nanog, Oct4, and c Myc. These observations were abrogated in the leptin-deficient ob/ob mice and ObR mutated db/db mice, indicating that these HFD-induced changes were responsible for effects downstream of the ObR. Consistent with this, the expression of the Class IA and III PI3Ks was increased following ObR activation in the gastric mucosa of HFD-fed mice. Together, these results suggest that HFD-induced lipotoxicity and deregulated organelle biosynthesis confer cancer stem cell-like properties to the gastric mucosa via signaling pathway mediated by leptin, PI3K and beta-catenin. PMID- 27693037 TI - Protein cysteine oxidation in redox signaling: Caveats on sulfenic acid detection and quantification. AB - Oxidation of critical signaling protein cysteines regulated by H2O2 has been considered to involve sulfenic acid (RSOH) formation. RSOH may subsequently form either a sulfenyl amide (RSNHR') with a neighboring amide, or a mixed disulfide (RSSR') with another protein cysteine or glutathione. Previous studies have claimed that RSOH can be detected as an adduct (e.g., with 5,5 dimethylcyclohexane-1,3-dione; dimedone). Here, kinetic data are discussed which indicate that few proteins can form RSOH under physiological signaling conditions. We also present experimental evidence that indicates that (1) dimedone reacts rapidly with sulfenyl amides, and more rapidly than with sulfenic acids, and (2) that disulfides can react reversibly with amides to form sulfenyl amides. As some proteins are more stable as the sulfenyl amide than as a glutathionylated species, the former may account for some of the species previously identified as the "sulfenome" - the cellular complement of reversibly oxidized thiol proteins generated via sulfenic acids. PMID- 27693039 TI - Real-time monitoring of artemin in vivo chaperone activity using luciferase as an intracellular reporter. AB - Artemin is an abundant thermostable protein in Artemia encysted embryos and considered as a stress protein, as its highly regulated expression is associated with stress resistance. Artemin cDNA was previously isolated and cloned from Artemia urmiana and artemin was found as an efficient molecular chaperone in vitro. Here, co-transformation of E. coli was performed with two expression vectors containing artemin and firefly luciferase for in vivo studies. The time course of luciferase inactivation at low and elevated temperatures showed that luciferase was rapidly inactivated in control cells, but it was found that luciferase was protected significantly in artemin expressing cells. More interestingly, luciferase activity was completely regained in heat treated artemin expressing cells at room temperature. In addition, in both stress conditions, similar to residual activity of luciferase, cell viability in induced cultures over-expressing artemin was significantly higher than non-expressed artemin cells. It can be suggested that artemin confers impressive resistance in stressful conditions when introduced into E. coli cells, which is due to that it protects proteins against aggregation. Such luciferase co-expression system can be used as a real-time reporter to investigate the activity of chaperone proteins in vivo and provide a rapid and simple test for molecular chaperones. PMID- 27693040 TI - miR-634 exhibits anti-tumor activities toward hepatocellular carcinoma via Rab1A and DHX33. AB - Deregulation of microRNAs contributes to the aberrant growth of hepatocellular carcinoma (HCC). Here, we showed that miR-634 expression was frequently decreased in HCC. Low miR-634 expression was significantly associated with larger tumor size, poorer tumor differentiation, advanced TNM stage, vascular invasion, absence of tumor capsule and unfavorable overall survival. Overexpression of miR 634 markedly attenuated cell viability, colony formation, tumor growth and metastasis, whereas miR-634 inhibition resulted in the opposite phenotypes. Furthermore, re-introduction of miR-634 induced cell apoptosis in vitro and in vivo. Mechanistically, miR-634 inhibited the expression of Rab1A and DHX33 via directly binding to the 3'-UTR of both genes. In clinical samples, the expression of Rab1A or DHX33 was reversely correlated with miR-634. Re-expression of Rab1A or DHX33 abrogated the miR-634-mediated inhibition of cell proliferation and migration. Collectively, our data suggest a tumor suppressor role of miR-634 in HCC. The newly identified miR-634/Rab1A or miR-634/DHX33 axis serves as a potential therapeutic target for the clinical management. PMID- 27693041 TI - Vibrio barjaei sp. nov., a new species of the Mediterranei clade isolated in a shellfish hatchery. AB - Seven isolates were obtained from different culture stages of carpet shell clam (Ruditapes decussatus) reared in a bivalve hatchery (Galicia, NW Spain). Three groups were differentiated by genotyping techniques and phenotypic profiles and representative trains were selected to further taxonomic studies. These strains were studied by a polyphasic approach and in basis of the phylogenetic analysis based on concatenated sequences of the five housekeeping genes ftsZ, gyrB, pyrH, recA and rpoA formed a tight group into the Mediterranei clade of the genus Vibrio. Percentages of genomic resemblance, including average nucleotide identity, in silico genome-to-genome comparison and wet DNA-DNA hybridization between the type strain and the closest relatives Vibrio mediterranei and Vibrio thalassae were below of the proposed boundaries for the definition of species. The novel isolates could be also differentiated from the related taxa on the basis of several phenotypic traits and fatty acid profiles. Results obtained support the description of a novel species into the Mediterranei clade, for which the name Vibrio barjaei sp. nov. is proposed, with strain 3062T (=CECT 9090T=CAIM 1921TT=LMG 29358T) as the type strain. PMID- 27693042 TI - A summary of the influence of exogenous estrogen administration across the lifespan on the GH/IGF-1 axis and implications for bone health. AB - Bone growth, development, and remodeling are modulated by numerous circulating hormones. Throughout the lifespan, the extent to which each of the hormones impacts bone differs. Understanding the independent and combined impact of these hormones on controlling bone remodeling allows for the development of more informed decision making regarding pharmacology, specifically the use of hormonal medication, at all ages. Endocrine control of bone health in women is largely dictated by the growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis and the hypothalamic-pituitary-ovarian (HPO) axis. Growth hormone, secreted from the pituitary gland, stimulates cells in almost every tissue to secrete IGF-1, although the majority of circulating IGF-1 is produced hepatically. Indeed, systemic IGF-1 concentrations have been found to be correlated with bone mineral density (BMD) in both pre- and post-menopausal women and is often used as a marker of bone formation. Sex steroids produced by the ovaries, namely estradiol, mediate bone resorption through binding to estrogen receptors on osteoclasts and osteoblasts. Specifically, by increasing osteoclast apoptosis and decreasing osteoblast apoptosis, adequate estrogen levels prevent excessive bone resorption, which helps to explain the rapid decline in bone mass that occurs with the menopausal decrease in estrogen production. Though there are documented correlations between endogenous estrogen concentrations and GH/IGF-1 dynamics, this relationship changes across the lifespan as sex-steroid dynamics fluctuate and, possibly, as tissue responsiveness to GH stimulation decreases. Aside from the known role of endogenous sex steroids on bone health, the impact of exogenous estrogen administration is of interest, as exogenous formulations further modulate GH and IGF-1 production. However, the effect and extent of GH and IGF-1 modulation seems to be largely dependent on age at administration and route of administration. Specifically, premenopausal women using combined oral contraceptive therapy (COC), post-menopausal women taking oral hormone therapy (HT), and both pre- and post-menopausal women using a transdermal form of estrogen therapy (COC or HT) demonstrate disparate GH/IGF-1 responses to exogenous estrogen. This review serves to summarize what is currently known regarding the influence of exogenous estrogen administration across the lifespan on the GH/IGF-1 axis and implications for bone health. PMID- 27693043 TI - Influence of design and clinical factors on the removal force ratio in tapered implant-abutment interfaces. AB - STATEMENT OF PROBLEM: A previous study investigated the effects of the preload and taper-angle mismatch in tapered implant systems on the removal force characteristics of the self-locking mechanism. The present study builds upon the previous one and introduces the effects of the time elapsed between insertion and removal and the presence of saliva in the implant-abutment interface as 2 new additional parameters. PURPOSE: The purpose of this in vitro study was to elucidate the influences of design and clinical parameters on the removal force for implant systems that use tapered interference fit (TIF) type connections by measuring the force needed to remove an abutment from an implant. MATERIAL AND METHODS: Ninety-six implants with tapered abutment-implant interfaces specifically built for an unreplicated factorial design were tested on a custom built workbench for removal force. Four levels were chosen for the preload, FP, and the taper mismatch Deltatheta; 3 levels for the wait time t; and 2 levels for the saliva presence s at the interface. A regression model was used based on physical reasoning and a theoretical understanding of the interface. A 4-way ANOVA was used to evaluate the influence of the main effects and interactions (alpha=.05). RESULTS: The experiments strongly indicated that preload, taper mismatch, and saliva presence are relevant variables in removal force. The wait time becomes important when its effect is evaluated along with the preload. CONCLUSIONS: The results of this study can be used for decision making in the design and use of TIF type systems. The study supports the use of artificial saliva in any implant design experiment because of its significance in the removal force of the abutment. PMID- 27693044 TI - [The adolescent abstainers: A risk group?] AB - OBJECTIVE: If abstinence from substance in adolescents may nowadays be regarded statistically as a deviant behavior, what is its significance from a developmental point of view? The aim of this article is to examine the mental health characteristics and the social integration of adolescent abstainers. METHODS: A comprehensive literature review of epidemiological studies including data on adolescent abstainers was conducted. RESULTS: Compared to the abundant literature devoted to adolescent substance abusers, few studies report data on adolescent abstainers. In addition, many methodological problems limit their interpretability and their comparison. However that may be, this body of work suggests that if abstinence may be due to something intrinsic about the individual (such as psychosocial adjustment difficulties, personality traits or gender), many other environmental factors (such as family background of temperance, cultural practices, upbringing or religion) may determine abstaining behavior. By this way, from a psychopathological angle, adolescent abstainers certainly constitute a more heterogeneous group than the adolescent substance abusers. Some of them are quite psychologically healthy, whereas others are more socially withdrawn and may suffer from emotional disorders. CONCLUSION: In terms of prevention, these data highlight the need for longitudinal prospective studies examining the psychosocial status of adolescent abstainers, their antecedents, their outcome and their motivations. PMID- 27693045 TI - Use of ECG-gated computed tomography, echocardiography and selective angiography in five dogs with pulmonic stenosis and one dog with pulmonic stenosis and aberrant coronary arteries. AB - Pulmonic stenosis (PS) is the most common congenital cardiac disease in dogs. Boxers and English bulldogs are among the most commonly affected breeds and also commonly associated with an aberrant coronary artery (CA). If an aberrant CA is suspected and balloon valvuloplasty indicated, an intra-operative angiography is recommended prior to the procedure. ECG-gated computed tomography (CT) can be used to screen for CA anomalies in a quick and minimally-invasive way (preventing side effects associated with selective catheter angiography) and allowing early planning of the procedure. The aim of this case series was to report CT findings associated with PS diagnosed by echocardiography. Our database was retrospectively searched for cases of dogs with PS diagnosed by echocardiography, where an ECG-gated CT was performed. A total of six cases were retrieved: all were diagnosed with severe PS. Four dogs had concurrent congenital defects: two dogs had a patent ductus arteriosus, one dog had a ventricular septal defect and an overriding aorta, one dog had an aberrant CA. Detailed CT findings of all cases were reported, including one case of a patent ductus arteriosus and an overriding aorta not identified by transthoracic echocardiography. In addition, an abnormal single left coronary ostium, with a pre-pulmonic right CA was described. In conclusion, despite echocardiography remaining the gold standard for diagnosis and assessment of PS, ECG-gated-CT angiography is a complementary diagnostic method that may provide additional relevant information, shorten surgery/anaesthesia time and reduce the amount of radiation to which the clinician is subjected. PMID- 27693046 TI - Glycerophosphodiesterase GDE2 Promotes Neuroblastoma Differentiation through Glypican Release and Is a Marker of Clinical Outcome. AB - Neuroblastoma is a pediatric embryonal malignancy characterized by impaired neuronal differentiation. A better understanding of neuroblastoma differentiation is essential for developing new therapeutic approaches. GDE2 (encoded by GDPD5) is a six-transmembrane-domain glycerophosphodiesterase that promotes embryonic neurogenesis. We find that high GDPD5 expression is strongly associated with favorable outcome in neuroblastoma. GDE2 induces differentiation of neuroblastoma cells, suppresses cell motility, and opposes RhoA-driven neurite retraction. GDE2 alters the Rac-RhoA activity balance and the expression of multiple differentiation-associated genes. Mechanistically, GDE2 acts by cleaving (in cis) and releasing glycosylphosphatidylinositol-anchored glypican-6, a putative co receptor. A single point mutation in the ectodomain abolishes GDE2 function.

AB - Light-dependent protochlorophyllide oxidoreductase (POR, E.C. 1.3.1.33) is a plant enzyme that directly needs light to conduct a biochemical reaction. In the present paper we confirmed that POR forms large oligomers in solution before binding of substrates. We carried out the research using different techniques: cross-linking, native gel electrophoresis and FRET measurements. Mass spectrometry analysis of the cross-link products provided the first structural data about the organisation of the oligomer of POR. The results indicated that the catalytic motifs of the adjacent subunits become close to each other upon binding of substrates. Moreover, we identified two mutations of POR that disturbed its oligomerisation properties: Delta85-88 and Delta240-270. Additionally, a complete loss of the catalytic activity was observed for the following mutations: Delta189-194, Delta240-270, Delta318-331 and Delta392-393. PMID- 27693050 TI - Circulating miRNA as fine regulators of the physiological responses to physical activity: Pre-analytical warnings for a novel class of biomarkers. AB - MicroRNAs are endogenous non-coding RNAs that post-transcriptionally regulate gene expression by specifically binding the target mRNA and by consequently inducing its degradation. miRNAs can be released into the circulation where they remain stable and they can be measured. Their changes reflect individual biologic adaptation to exposures to specific environmental conditions. As such, measurement of circulating microRNAs represents an opportunity to evaluate biologic changes associated with interventions such as exercise and diet. Physical activity is, indeed, a very important modifying factor for circulating miRNAs. Toward their use in clinical settings several issues should be still solved. Their clinical application is hindered by the high heterogeneity of the analytical procedures used for their measurements. Furthermore, several pre analytical concerns equally reduce the clinical applicability of miRNA. Pre analytical phase in sports medicine is an important issue both because, often the conditions in which sampling are performed are peculiar (and not always canonical) and because some of the tested parameters, in the case of professional athletes, enters in routine anti-doping testing and, as such, they should be treated according to precise rules in order to avoid any false positive results. Aim of this review is to give an overview of the main available knowledges about the pre-analytical management of the sample for circulating miRNA evaluation along with the importance of miRNA as regulators of the response to physical activity and their possible future use in anti-doping settings. PMID- 27693049 TI - The antiangiogenic and antitumor activities of the N-terminal fragment of endostatin augmented by Ile/Arg substitution: The overall structure implicated the biological activity. AB - The antiangiogenic and antitumor activities of the 27-amino acid fragment corresponding to the N-terminal domain of endostatin were shown to be dependent on a Zn-binding loop in the N-terminus. To investigate whether the regions outside of the N-terminal loop play a role in the peptide function, the structure and function of a variant containing Ile26Arg mutation (ES-R) were compared with those of the native peptide (ES-Zn). Structural analysis using far-UV CD, intrinsic fluorescence and molecular dynamics simulation provided information regarding the overall changes upon the mutation. In addition, the docking simulations predicted a higher affinity of ES-R to integrins alphavbeta3 and alpha5beta1 than ES-Zn and a profound reorganization of the binding residues throughout the sequence. In Human Umbilical Vein Endothelial Cells (HUVECs), ES-R inhibited the tube formation and activated caspase-3 more strongly than do ES-Zn. Based on in vivo studies, the growth of breast tumor and expression of CD31, Bcl 2 and nonfunctional p53 were inhibited more effectively by ES-R than by ES-Zn. We conclude that the C-terminal region is involved in the peptide function through some global structural effects. PMID- 27693047 TI - Expression of Idh1R132H in the Murine Subventricular Zone Stem Cell Niche Recapitulates Features of Early Gliomagenesis. AB - Isocitrate dehydrogenase 1 mutations drive human gliomagenesis, probably through neomorphic enzyme activity that produces D-2-hydroxyglutarate. To model this disease, we conditionally expressed Idh1R132H in the subventricular zone (SVZ) of the adult mouse brain. The mice developed hydrocephalus and grossly dilated lateral ventricles, with accumulation of 2-hydroxyglutarate and reduced alpha ketoglutarate. Stem and transit amplifying/progenitor cell populations were expanded, and proliferation increased. Cells expressing SVZ markers infiltrated surrounding brain regions. SVZ cells also gave rise to proliferative subventricular nodules. DNA methylation was globally increased, while hydroxymethylation was decreased. Mutant SVZ cells overexpressed Wnt, cell-cycle and stem cell genes, and shared an expression signature with human gliomas. Idh1R132H mutation in the major adult neurogenic stem cell niche causes a phenotype resembling gliomagenesis. PMID- 27693051 TI - High-density lipoprotein subclass profile and mortality in patients with coronary artery disease: Results from the GENES study. AB - BACKGROUND: High-density lipoproteins (HDLs) are highly heterogeneous particles, and the specific contribution of each subclass to the prediction of clinical outcome in coronary artery disease (CAD) remains controversial. OBJECTIVE: To examine the relationship between HDL subclass profile and mortality in patients with CAD, using a new and rapid electrophoretic quantitative method for the assessment of HDL particle size phenotype. METHODS: We investigated 403 patients with CAD admitted for cardiovascular examination in the context of evaluation and management of CAD. HDL subclass distribution was analysed using the Quantimetrix Lipoprint(r) HDL system. Cumulative survival of patients according to lipid variables was determined by the Kaplan-Meier method. The relationship between baseline variables and outcome criteria was assessed using Cox proportional hazards regression analysis. RESULTS: During follow-up (9.8+/-3.1 years) the mortality rate was 31.0%; 60.8% of deaths were related to CAD. The concentration of total HDL cholesterol was similar in deceased patients (42+/-13mg/dL) and alive patients (43+/-12mg/dL); the concentrations of small, intermediate and large HDL cholesterol subclasses were not significantly different in alive and deceased patients (P=0.17, P=0.34 and P=0.81, respectively). We did not observe any independent associations between overall or cardiovascular mortality and total HDL cholesterol or any HDL subclass. However, heart rate, left ventricular ejection fraction and severity score for coronary atherosclerosis were more associated with mortality than classical cardiovascular risk factors. CONCLUSIONS: HDL subclass profile is not associated with mortality in patients with CAD. Further investigations linking HDL subclass repartition with prediction of residual cardiovascular risk are required. PMID- 27693052 TI - Prehospital and in-hospital course of care for patients with acute heart failure: Features and impact on prognosis in "real life". AB - BACKGROUND: Acute heart failure (AHF) is a life-threatening medical emergency for which no new effective therapies have emerged in recent decades. No previous study has exhaustively described the entire course of care of AHF patients from first medical contact to hospital discharge or assessed its impact on prognosis. AIM: To fully describe the course of care and analyze its influence on outcomes in patients hospitalized with an AHF syndrome in an academic university center. METHODS: One hundred and nineteen adults with AHF from three public academic university hospitals were consecutively enrolled in a multicenter prospective observational cohort study. All of the emergency departments, intensive care units, coronary care units, cardiology wards and other medical wards participated in the study. RESULTS: The composite primary outcome (6-month rate of cardiovascular death, readmission for acute heart failure, acute coronary syndrome or stroke) occurred in 59% of patients. This rate was high and similar regardless of first medical contact, type of transport, first medical department of admission and number of medical departments involved in the course of care. A cardiologist was involved in management in 80% of cases. The global median hospital stay was shorter with cardiology vs non-cardiology management (7 days [interquartile range 4-11] vs 10 days [interquartile range 7-18]; P=0.003). History of hypertension (P=0.004), need for non-invasive ventilation (P=0.023) and Lee prognostic score (P=0.028) were independently associated with the primary outcome. CONCLUSIONS: Morbimortality and readmissions were high regardless of the course of care in patients admitted for AHF in real life. The reduction in hospital stay when cardiologists were involved in management encourages the creation of "mobile AHF cardiology teams". PMID- 27693053 TI - Does Pelvic Sagittal Inclination in the Supine and Standing Positions Change Over 10 Years of Follow-Up After Total Hip Arthroplasty? AB - BACKGROUND: Functional anteversion and inclination of the cup change as the pelvic sagittal inclination (PSI) changes. The purposes of this study were to investigate the chronological changes of PSI during a 10-year follow-up period after total hip arthroplasty (THA) and to report the characteristics of patients who showed a greater than 10 degrees change in the PSI from the supine to the standing position. METHODS: The subjects were 70 patients who were followed up for 10 years after THA. PSI values in the supine and standing positions were measured by 2D-3D matching using computed tomography images and pelvic radiographs. PSI values before THA and 1, 5, and 10 years after THA were compared in both the supine and standing positions. RESULTS: Supine PSI showed less than 5 degrees of change, whereas standing PSI showed a significant decrease with time over the 10-year period. Although 43% of patients with less than 10 degrees of difference in the PSI between the supine and standing positions before THA increased PSI posteriorly (reclining) more than 10 degrees in standing from the supine position at 10 years, no late dislocation was observed. CONCLUSION: Supine PSI showed no significant change, but standing PSI showed a significant increase posteriorly with time over a 10-year period. However, this PSI change did not reach the level that it caused negative consequences such as late dislocation. The pelvic position in the supine position might still be a good functional reference position of the pelvis for aiming to achieve proper cup alignment at 10 years. PMID- 27693054 TI - A Randomized Clinical Trial Comparing Posterior Cruciate-Stabilizing vs Posterior Cruciate-Retaining Prostheses in Primary Total Knee Arthroplasty: 10-Year Follow Up. AB - BACKGROUND: This 10-year follow-up compares health-related quality of life (HRQL) and reoperations in 100 subjects who were randomized to receive posterior cruciate ligament substituting (PS) or posterior cruciate ligament retaining (CR) total knee arthroplasty. We previously reported 2-year results. METHODS: Subjects were enrolled preoperatively and randomized at surgery. Subjects completed HRQL questionnaires at all evaluation points. Subjects were re-evaluated at 2 and 10 years with reoperations determined through regional medical record review and patient report. RESULTS: Over 10 years, 25 (25%) subjects died, 2 subjects were revised and withdrew, and 11 (11%) subjects were lost to follow-up. Of survivors, 62 of 75 (83%) were evaluated at 10 years. Twenty-eight (37%) subjects provided HRQL, radiographic, and reoperation status, 28 (37%) subjects completed HRQL evaluations and reoperation status only, and 6 (8%) subjects provided radiographic and reoperation follow-up. Both groups retained good HRQL between 2 and 10 years with no group differences noted (P > .35). One revision (CR subject), secondary to deep joint infection, occurred within 2 years with 1 further revision (PS subject) occurring at 3 years postoperatively. One subject (PS subject) required manipulation under anesthesia within 3 months of surgery. Four subjects required late patellar resurfacing (1 CR subject, 3 PS subjects) but were retained in the 10-year evaluation. Overall, reoperations were not significantly different between groups (P = .26). CONCLUSION: Over 10 years postoperatively, both the PS and CR total knee arthroplasty performed well with subjects reporting acceptable levels of HRQL up to 10 years postoperatively; low levels of revision or reoperation were reported in both groups.

PMID- 27693056 TI - Mechanistic Details of Early Steps in Coenzyme Q Biosynthesis Pathway in Yeast. AB - Coenzyme Q (Q) is a redox lipid that is central for the energetic metabolism of eukaryotes. The biosynthesis of Q from the aromatic precursor 4-hydroxybenzoic acid (4-HB) is understood fairly well. However, biosynthetic details of how 4-HB is produced from tyrosine remain elusive. Here, we provide key insights into this long-standing biosynthetic problem by uncovering molecular details of the first and last reactions of the pathway in the yeast Saccharomyces cerevisiae, namely the deamination of tyrosine to 4-hydroxyphenylpyruvate by Aro8 and Aro9, and the oxidation of 4-hydroxybenzaldehyde to 4-HB by Hfd1. Inactivation of the HFD1 gene in yeast resulted in Q deficiency, which was rescued by the human enzyme ALDH3A1. This suggests that a similar pathway operates in animals, including humans, and led us to propose that patients with genetically unassigned Q deficiency should be screened for mutations in aldehyde dehydrogenase genes, especially ALDH3A1. PMID- 27693058 TI - Biomimetic Thioesters as Probes for Enzymatic Assembly Lines: Synthesis, Applications, and Challenges. AB - Thioesters play essential roles in many biosynthetic pathways to fatty acids, esters, polyketides, and non-ribosomal peptides. Coenzyme A (CoA) and related phosphopantetheine thioesters are typically employed as activated acyl units for diverse C-C, C-O, and C-N coupling reactions. To study and control these enzymatic assembly lines in vitro and in vivo structurally simplified analogs such as N-acetylcysteamine (NAC) thioesters have been developed. This review gives an overview on experimental strategies enabled by synthetic NAC thioesters, such as the elucidation of complex biosynthetic pathways and enzyme mechanisms as well as precursor-directed biosynthesis and mutasynthesis. The review also summarizes synthetic protocols and protection group strategies to access these versatile synthetic tools, which are reactive and often unstable compounds. In addition, alternative phosphopantetheine thioester mimics are presented that can be used as protein tags or suicide inhibitors for protein crosslinking and off loading probes to elucidate polyketide intermediates. PMID- 27693057 TI - Analysis of the RNA Binding Specificity Landscape of C5 Protein Reveals Structure and Sequence Preferences that Direct RNase P Specificity. AB - RNA binding proteins (RBPs) are typically involved in non-equilibrium cellular processes, and specificity can arise from differences in ground state, transition state, or product states of the binding reactions for alternative RNAs. Here, we use high-throughput methods to measure and analyze the RNA association kinetics and equilibrium binding affinity for all possible sequence combinations in the precursor tRNA binding site of C5, the essential protein subunit of Escherichia coli RNase P. The results show that the RNA sequence specificity of C5 arises due to favorable RNA-protein interactions that stabilize the transition state for association and bound enzyme-substrate complex. Specificity is further impacted by unfavorable RNA structure involving the C5 binding site in the ground state. The results illustrate a comprehensive quantitative approach for analysis of RNA binding specificity, and show how both RNA structure and sequence preferences of an essential protein subunit direct the specificity of a ribonucleoprotein enzyme. PMID- 27693060 TI - Conformation Selective Antibody Enables Genome Profiling and Leads to Discovery of Parallel G-Quadruplex in Human Telomeres. AB - G-quadruplexes are specialized secondary structures in nucleic acids that possess significant conformational polymorphisms. The precise G-quadruplex conformations in vivo and their relevance to biological functions remain controversial and unclear, especially for telomeric G-quadruplexes. Here, we report a novel single chain variable fragment (scFv) antibody, D1, with high binding selectivity for parallel G-quadruplexes in vitro and in vivo. Genome-wide chromatin immunoprecipitation using D1 and deep-sequencing revealed the consensus sequence for parallel G-quadruplex formation, which is characterized by G-rich sequence with a short loop size (<3 nt). By using D1, telomeric parallel G-quadruplex was identified and its formation was regulated by small molecular ligands targeting and telomere replication. Together, parallel G-quadruplex specific antibody D1 was found to be a valuable tool for determination of G-quadruplex and its conformation, which will prompt further studies on the structure of G-quadruplex and its biological implication in vivo. PMID- 27693059 TI - Bidirectional Allosteric Communication between the ATP-Binding Site and the Regulatory PIF Pocket in PDK1 Protein Kinase. AB - Allostery is a phenomenon observed in many proteins where binding of a macromolecular partner or a small-molecule ligand at one location leads to specific perturbations at a site not in direct contact with the region where the binding occurs. The list of proteins under allosteric regulation includes AGC protein kinases. AGC kinases have a conserved allosteric site, the phosphoinositide-dependent protein kinase 1 (PDK1)-interacting fragment (PIF) pocket, which regulates protein ATP-binding, activity, and interaction with substrates. In this study, we identify small molecules that bind to the ATP binding site and affect the PIF pocket of AGC kinase family members, PDK1 and Aurora kinase. We describe the mechanistic details and show that although PDK1 and Aurora kinase inhibitors bind to the conserved ATP-binding site, they differentially modulate physiological interactions at the PIF-pocket site. Our work outlines a strategy for developing bidirectional small-molecule allosteric modulators of protein kinases and other signaling proteins. PMID- 27693061 TI - Sample preparation procedures utilized in microbial metabolomics: An overview. AB - Bacteria are remarkably diverse in terms of their size, structure and biochemical properties. Due to this fact, it is hard to develop a universal method for handling bacteria cultures during metabolomic analysis. The choice of suitable processing methods constitutes a key element in any analysis, because only appropriate selection of procedures may provide accurate results, leading to reliable conclusions. Because of that, every analytical experiment concerning bacteria requires individually and very carefully planned research methodology. Although every study varies in terms of sample preparation, there are few general steps to follow while planning experiment, like sampling, separation of cells from growth medium, stopping their metabolism and extraction. As a result of extraction, all intracellular metabolites should be washed out from cell environment. What is more, extraction method utilized cannot cause any chemical decomposition or degradation of the metabolome. Furthermore, chosen extraction method should correlate with analytical technique, so it will not disturb or prolong following sample preparation steps. For those reasons, we observe a need to summarize sample preparation procedures currently utilized in microbial metabolomic studies. In the presented overview, papers concerning analysis of extra- and intracellular metabolites, published over the last decade, have been discussed. Presented work gives some basic guidelines that might be useful while planning experiments in microbial metabolomics. PMID- 27693062 TI - Evaluation of particulate matter emissions from manganese alloy production using life-cycle assessment. AB - Life-cycle assessments (LCAs) provide a wealth of industry data to assist in evaluating the environmental impacts of industrial processes and product supply chains. In this investigation, data from a recent LCA covering global manganese alloy production was used to evaluate sources of particulate matter (PM) emissions associated with the manganese alloy supply chain. The analysis is aimed at providing an empirical, industry-averaged breakdown of the contribution that processes and emissions controls have on total emissions, manganese releases and occupational exposure. The assessment shows that 66% of PM emissions associated with manganese production occur beyond manganese facilities. Direct or on-site emissions represent 34% of total PM and occur predominantly as disperse sources during mineral extraction and hauling, and as primary furnace emissions. The largest contribution of manganese-bearing PM at ground-level is associated with fugitive emissions from metal and slag tapping, casting, crushing and screening. The evaluation provides a high-level ranking of emissions by process area, to assist in identifying priority areas for industry-wide initiatives to reduce emissions and occupational exposure of manganese. The range of PM emission levels in industry indicate that further enhancements in PM emissions can be achieved by sharing of best practices in emissions controls, limiting furnace conditions which lead to by-passing of emissions controls and application of secondary emission controls to capture fugitive emissions during tapping and casting. The LCA approach to evaluating PM emissions underscores the important role that process optimization and resource efficiency have on reducing PM emissions throughout the manganese supply chain. PMID- 27693063 TI - On the validity and errors of the pseudo-first-order kinetics in ligand-receptor binding. AB - The simple bimolecular ligand-receptor binding interaction is often linearized by assuming pseudo-first-order kinetics when one species is present in excess. Here, a phase-plane analysis allows the derivation of a new condition for the validity of pseudo-first-order kinetics that is independent of the initial receptor concentration. The validity of the derived condition is analyzed from two viewpoints. In the first, time courses of the exact and approximate solutions to the ligand-receptor rate equations are compared when all rate constants are known. The second viewpoint assesses the validity through the error induced when the approximate equation is used to estimate kinetic constants from data. Although these two interpretations of validity are often assumed to coincide, we show that they are distinct, and that large errors are possible in estimated kinetic constants, even when the linearized and exact rate equations provide nearly identical solutions. PMID- 27693064 TI - Colorectal cancer with venous tumor thrombosis. AB - Colorectal cancer is seldom accompanied by venous tumor thrombosis, and little is known about the features of venous tumor thrombosis in colorectal cancer. However, some reports show that colorectal cancer patients can develop venous tumor thrombosis and warn clinicians not to overlook this complication. In this report, we perform a review of 43 previously reported cases and investigate the characteristics of colorectal cancer accompanied by venous tumor thrombosis. The histological type of more than half of the cases was moderately differentiated adenocarcinoma, which is known to be aggressive. Among 41 cases with available data on liver metastasis, eight patients had synchronous liver metastasis, and liver metastatic recurrence after surgical resection was indicated in 10 patients. This liver metastatic rate was high compared to general colorectal cancer. However, 11 of 43 patients with venous tumor thrombosis could survive for more than 2 years after the diagnosis, although five of the 11 patients had liver metastasis. A long survival can be anticipated for patients following complete tumor resection and adjuvant chemotherapy. A greater accumulation of cases will help elucidate the characteristics of colorectal cancer with venous tumor thrombosis and improve the treatment strategy. PMID- 27693065 TI - Gastrectomy with limited surgery for elderly patients with gastric cancer. AB - BACKGROUND/OBJECTIVE: Elderly patients with gastric cancer can receive standard gastrectomy or gastrectomy with reduced nodal dissection, i.e., limited surgery, in order to prevent postoperative complications. This study evaluated the feasibility of gastrectomy with limited surgery for elderly patients with gastric cancer. METHODS: A total of 267 elderly patients (>=70 years old) were divided into two groups according to the level of nodal dissection: patients who received nodal dissection according to guidelines were included in the standard surgery group (standard group), and those who received reduced nodal dissection were included in the limited surgery group (limited group). The surgical outcomes of the two groups were compared. RESULTS: There were 170 patients in the standard group and 97 patients in the limited group. The limited group had significantly poorer nutrition status and a significantly higher proportion with comorbidities. Morbidity and mortality were similar in both groups. Multivariate analysis showed that the overall survival rates were significantly worse in patients with advanced age, male gender, low body mass index, low prognostic nutrition index, and higher tumor stage. The disease-specific survival rate was significantly lower in the limited group than in the standard group (p<0.001). CONCLUSION: Gastrectomy according to the gastric treatment guidelines for elderly patients with gastric cancer is recommended. Elderly male patients with poor nutrition have poor prognosis; prognostic nutrition index <40. Limited surgery is a treatment option for such patients. PMID- 27693066 TI - Tension Gastrothorax as a Complication of Bochdalek Hernia. PMID- 27693067 TI - Esophageal Rupture After Ghost Pepper Ingestion. AB - BACKGROUND: The ghost pepper, or "bhut jolokia," is one of the hottest chili peppers in the world. Ghost peppers have a measured "heat" of > 1,000,000 Scoville heat units (SHU), more than twice the strength of a habanero pepper. To our knowledge, no significant adverse effects of ghost pepper ingestion have been reported. CASE REPORT: A 47-year-old man presented to the Emergency Department (ED) with severe abdominal and chest pain subsequent to violent retching and vomiting after eating ghost peppers as part of a contest. A subsequent chest x ray study showed evidence of a left-sided pleural effusion and patchy infiltrates. A computed tomography scan of the abdomen and pelvis showed pneumomediastinum with air around the distal esophagus, suggestive of a spontaneous esophageal perforation and a left-sided pneumothorax. The patient was intubated and taken immediately to the operating room, where he was noted to have a 2.5-cm tear in the distal esophagus, with a mediastinal fluid collection including food debris, as well as a left-sided pneumothorax. The patient was extubated on hospital day 14, and was discharged home with a gastric tube in place on hospital day 23. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Spontaneous esophageal rupture, Boerhaave syndrome, is a rare condition encountered by emergency physicians, with a high mortality rate. This case serves as an important reminder of a potentially life- threatening surgical emergency initially interpreted as discomfort after a large spicy meal. PMID- 27693068 TI - A Hanging and Its Complications. AB - Hanging has become the second most common form of successful suicide in the United States. Along with a high mortality rate, the long-term morbidity is consequential for both the individual patient and society. A thorough knowledge of the clinical approach will assist the emergency physician in providing optimal care and helping to minimize delayed respiratory complications. Using a case based scenario, the initial management strategies along with rational evidence based treatments are reviewed.

PMID- 27693070 TI - Is There a Role for Intravenous Subdissociative-Dose Ketamine Administered as an Adjunct to Opioids or as a Single Agent for Acute Pain Management in the Emergency Department? AB - BACKGROUND: Whether acute or chronic, emergency physicians frequently encounter patients reporting pain. It is the responsibility of the emergency physician to assess and evaluate, and if appropriate, safely and effectively reduce pain. Recently, analgesics other than opioids are being considered in an effort to provide safe alternatives for pain management in the emergency department (ED). Opioids have significant adverse effects such as respiratory depression, hypotension, and sedation, to say nothing of their potential for abuse. Although ketamine has long been used in the ED for procedural sedation and rapid sequence intubation, it is used infrequently for analgesia. Recent evidence suggests that ketamine use in subdissociative doses proves to be effective for pain control and serves as a feasible alternative to traditional opioids. This paper evaluates ketamine's analgesic effectiveness and safety in the ED. METHODS: This is a literature review of randomized controlled trials, systematic reviews, meta analyses, and observational studies evaluating ketamine for pain control in the ED setting. Based on these search parameters, eight studies were included in the final analysis and graded based on the American Academy of Emergency Medicine Clinical Practice Committee manuscript review process. RESULTS: A total of eight papers were reviewed in detail and graded. Recommendations were given based upon this review process. CONCLUSIONS: Subdissociative-dose ketamine (low-dose ketamine) is effective and safe to use alone or in combination with opioid analgesics for the treatment of acute pain in the ED. Its use is associated with higher rates of minor, but well-tolerated adverse side effects. PMID- 27693071 TI - Role of Pediatric Emergency Physicians in Identifying Bullying. AB - BACKGROUND: Bullying is an important public health issue with broad implications. Although this issue has been studied extensively, there is limited emergency medicine literature addressing bullying. The emergency department (ED) physician has a unique opportunity to identify children and adolescents that are victims of bullying, and make a difference in their lives. OBJECTIVE: Our aim is to discuss the role of the emergency physician (EP) in identifying patients who have been victims of bullying and how to provide effective management as well as referral for further resources. DISCUSSION: This document provides a framework for recognizing, stabilizing, and managing children who have experienced bullying. With the advent of social media, bullying behavior is not limited to in-person situations, and often occurs via electronic communication, further complicating recognition because it may not impart any physical harm to the child. Recognition of bullying requires a high level of suspicion, as patients may not offer this history. After the stabilization of any acute or overt indications of physical injury, along with obtaining a history of the mechanism of injury, the EP has the opportunity to identify the existence of bullying as the cause of the injury, and can address the issue in the ED while collaborating with "physician-extenders," such as social workers, toward identifying local resources for further support. CONCLUSIONS: The ED is an important arena for the assessment and management of children who have experienced bullying. It is imperative that EPs on the front lines of patient care address this public health epidemic. They have the opportunity to exert a positive impact on the lives of the children and families who are the victims of bullying. PMID- 27693072 TI - Acute Toxicity from Topical Cocaine for Epistaxis: Treatment with Labetalol. AB - BACKGROUND: Topical cocaine is sometimes used for the treatment of epistaxis, as it has both potent anesthetic and vasoconstrictive properties. Cocaine has unpredictable cardiovascular effects, such as sudden hypertension, tachycardia, coronary arterial vasoconstriction, and dysrhythmia. CASE REPORT: We report a case of acute iatrogenic cardiovascular toxicity from the use of topical cocaine in a 56-year-old man presenting to the Emergency Department with profound epistaxis. To prepare for cauterization and nasal packing, the patient received 4% topical cocaine-soaked nasal pledgets. He became hypertensive, tachypneic, tachycardic, and dysphoric immediately after administration. To directly counter these adverse hyperadrenergic effects, the patient was given 10 mg intravenous labetalol, a mixed beta- and alpha-blocker. This instantly normalized his vital signs and adverse subjective effects. His epistaxis was successfully treated, and he was discharged 1 h later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We believe that emergency physicians should be aware of the unpredictable acute cardiovascular toxicity of topical cocaine. Labetalol represents an effective first-line treatment, which, unlike benzodiazepines, directly counters the pharmacologic effects of cocaine and has no respiratory or sedative side effects. Labetalol, with its mixed beta/alpha-blocking properties, also mitigates the potential for "unopposed alpha-stimulation." PMID- 27693073 TI - Jaundice, Anemia, and Hypoxemia.

PMID- 27693075 TI - Best Clinical Practice: Current Controversies in Evaluation of Low-Risk Chest Pain-Part 1. AB - BACKGROUND: Chest pain is a common presentation to the emergency department (ED), though the majority of patients are not diagnosed with acute coronary syndrome (ACS). Many patients are admitted to the hospital due to fear of ACS. OBJECTIVE: Our aim was to investigate controversies in low-risk chest pain evaluation, including risk of missed ACS, stress test, and coronary computed tomography angiography (CCTA). DISCUSSION: Chest pain accounts for 10 million ED visits in the United States annually. Many patients are at low risk for a major cardiac adverse event (MACE). With negative troponin and nonischemic electrocardiogram (ECG), the risk of MACE and myocardial infarction (MI) is < 1%. The American Heart Association recommends further evaluation in low- to intermediate-risk patients within 72 h. These modalities add little to further risk stratification. These evaluations do not appropriately risk stratify patients who are already at low risk, nor do they diagnose acute MI. CCTA is an anatomic evaluation of the coronary vasculature with literature support to decrease ED length of stay, though it is associated with downstream testing. Literature is controversial concerning further risk stratification in already low-risk patients. CONCLUSIONS: With nonischemic ECG and negative cardiac biomarker, the risk of ACS approaches < 1%. Use of stress test and CCTA for risk stratification of low-risk chest pain patients is controversial. These tests may allow prognostication but do not predict ACS risk beyond ECG and troponin. CCTA may be useful for intermediate risk patients, though further studies are required. PMID- 27693076 TI - Comparison of Metal and Plastic Disposable Laryngoscope Blade with Reusable Macintosh Blade in Difficult and Inhalation Injury Airway Scenario: A Manikin Study. AB - BACKGROUND: Single-use plastic blades (SUPB) and single-use metal blades (SUMB) for direct laryngoscopy and tracheal intubation have not yet been compared with reusable metal blades (RUMB) in difficult airway scenarios. OBJECTIVE: The purpose of our manikin study was to compare the effectiveness of these different laryngoscope blades in a difficult airway scenario, as well as in a difficult airway scenario with simulated severe inhalation injury. METHODS: Thirty anesthetists performed tracheal intubation (TI) with each of the three laryngoscope blades in the two scenario manikins. RESULTS: In the inhalation injury scenario, SUPB were associated with prolonged intubation times when compared with the metal blades. In the inhalation injury scenario, both metal laryngoscope blades provided a quicker, easier, and safer TI. In the difficult airway scenario, intubation times were significantly prolonged in the SUPB group in comparison to the RUMB group, but there were no significant differences between the SUPB and the SUMB. In this scenario, the RUMB demonstrated the shortest intubation times and seems to be the most effective device. CONCLUSIONS: Generally, results are in line with previous studies showing significant disadvantages of SUPB in both manikin scenarios. Therefore, metal blades might be beneficial, especially in the airway management of patients with inhalation injury.

AB - OBJECTIVES: i) To assess the relationship between lipid markers and high sensitivity C-reactive protein (hs-CRP), and high-sensitivity cardiac troponin I (hs-cTnI) in the reference population, and ii) to evaluate the impact of lipid markers and hs-CRP on the 99th percentile upper reference limit (URL) for hs cTnI. METHODS: 531 questionnaire-identified presumably healthy individuals were enrolled in a single-center, cross-sectional study. Surrogate biomarkers for diabetes, myocardial and renal dysfunction were used to refine the healthy cohort (n=408). Lipid profile, total cholesterol:high-density lipoprotein cholesterol (HDL-C) ratio, non-HDL-C, apolipoprotein AI (apoAI), apolipoprotein B (apoB), apoB:apoAI ratio, lipoprotein(a), small dense low-density lipoprotein cholesterol (LDL-C) and hs-CRP were determined. RESULTS: Individuals with detectable vs. non detectable hs-cTnI concentrations more often showed elevated LDL-C (60% vs. 46%; p=0.002), apoB (73% vs. 61%; p=0.008), apoB:apoAI ratio (53% vs. 40%; p=0.005) and lipoprotein(a) (15% vs. 7%; p=0.015). The apoB:apoAI ratio and to a lesser extent other lipid markers, but not hs-CRP, were positively associated with hs cTnI concentration in univariate and multivariate analyses. Exclusion of individuals with elevated apoB:apoAI ratio or apoB, but not hs-CRP, lowered the 99th percentile URL in the healthy cohort respectively by 12.9% (6.2 vs. 5.4ng/L) and 14.5% (6.2 vs. 5.3ng/L). The corresponding reduction for both lipid biomarkers in the presumably healthy population was 24.0% (7.5 vs. 5.7ng/L). CONCLUSION: Our study demonstrates that atherogenic lipid markers, particularly apoB:apoAI ratio or apoB, influence the 99th percentile URL for hs-cTnI. PMID- 27693078 TI - Effect of HLA mismatching at HLA-A, -B, and -DRB1 for umbilical-cord blood transplantation in Taiwan. AB - Unrelated cord blood transplantation has become a reliable alternative therapy for children and adults owing to that one or two antigen/allele mismatches between a patient and the cord blood donor are acceptable without occurrence of graft-versus-host disease. To investigate the relationship between the number and types of mismatches and relapse, we compared the number of mismatched and non mismatched donor-recipient pairs, number of mismatched alleles, and number of mismatched antigens at each of the Human Leukocyte Antigen (HLA) -A, -B, and -DR loci, respectively. The result indicates that the number of mismatched antigens at the HLA-A locus was significantly associated with occurrence of relapse (X2P value=0.0243; RR=1.49, 95% CI: 1.04-2.13). Additionally, the number of mismatched donor-recipient pairs and the number of mismatched alleles at the HLA-DR locus was negatively associated with risks of relapse (X2P-value=0.0028; RR=0.52, 95% CI: 0.31-0.89). In this study, we found that the mismatch at the HLA-A locus is associated with increased risk of relapse; while the mismatch at the HLA-DR locus is innocuous. Hence, we suggest that the well-matched HLA-A alleles were most critical for matching HLA alleles between umbilical-cord blood transplantation donors and recipients. In other words, cord blood transplantation requires less stringent HLA matching, if there are two 5/6 or 4/6 HLA matched donors, it's better to choose HLA-A matched donor at least. PMID- 27693079 TI - Transcriptional regulation of the uncoupling protein-1 gene. AB - Regulated transcription of the uncoupling protein-1 (UCP1) gene, and subsequent UCP1 protein synthesis, is a hallmark of the acquisition of the differentiated, thermogenically competent status of brown and beige/brite adipocytes, as well as of the responsiveness of brown and beige/brite adipocytes to adaptive regulation of thermogenic activity. The 5' non-coding region of the UCP1 gene contains regulatory elements that confer tissue specificity, differentiation dependence, and neuro-hormonal regulation to UCP1 gene transcription. Two main regions-a distal enhancer and a proximal promoter region-mediate transcriptional regulation through interactions with a plethora of transcription factors, including nuclear hormone receptors and cAMP-responsive transcription factors. Co-regulators, such as PGC-1alpha, play a pivotal role in the concerted regulation of UCP1 gene transcription. Multiple interactions of transcription factors and co-regulators at the promoter region of the UCP1 gene result in local chromatin remodeling, leading to activation and increased accessibility of RNA polymerase II and subsequent gene transcription. Moreover, a commonly occurring A-to-G polymorphism in close proximity to the UCP1 gene enhancer influences the extent of UCP1 gene transcription. Notably, it has been reported that specific aspects of obesity and associated metabolic diseases are associated with human population variability at this site. On another front, the unique properties of the UCP1 promoter region have been exploited to develop brown adipose tissue-specific gene delivery tools for experimental purposes. PMID- 27693080 TI - The efficient cell-SELEX strategy, Icell-SELEX, using isogenic cell lines for selection and counter-selection to generate RNA aptamers to cell surface proteins. AB - Aptamers are short single-stranded nucleic acid molecules that are selected in vitro from a large random sequence library based on their high and specific affinity to a target molecule by a process known as SELEX. Cell-SELEX that employs whole living cells overexpressing the defined cell surface proteins (for selection) and appropriate mock cells (for counter-selection) has been widely used as a valid and feasible method for generating aptamers against specific cell surface proteins. However, the endogenous expression of target proteins in mock cells or the heterogeneity of surface proteins between selection and counter selection cells often impeded the isolation of proper aptamers against target proteins. To solve this problem, we developed "Isogenic cell-SELEX" (Icell SELEX in short) method, in which isogenic cell lines were manipulated for counter selection by microRNA-mediated silencing and for selection by overexpression of target proteins. As a model experiment, we targeted integrin alpha V (ITGAV), which is a major transmembrane receptor expressed in almost all the cells, and established ITGAV-overexpressed and -downregulated HEK293 cells for selection and counter-selection, respectively. By taking advantage of a hundred-fold difference in the expression level of ITGAV between these two isogenic cell lines, we easily isolated several anti-ITGAV aptamers, whose binding to the cell-surface ITGAV was confirmed by flow cytometry with the dissociation constant of 300-400 nM range. We assume that Icell-SELEX could be applicable to a wide range of cell-surface proteins including various transmembrane proteins of biological and pharmacological significance. PMID- 27693081 TI - H2AK119 monoubiquitination regulates Angiotensin II receptor mediated macrophage infiltration and renal fibrosis in type 2 diabetic rats. AB - Monocyte chemoattractant protein (MCP-1) and transforming growth factor-beta (TGF beta1)-markers of inflammation and fibrosis, are central to type 2 diabetic nephropathy (T2DN) progression. The epigenetic basis of their expression has also been explored to certain extent. H2A lysine 119 monoubiquitination (H2AK119Ub), a repressive chromatin mark regulates progression of hyperglycaemia induced fibrosis in glomerular mesangial cells. However, how H2AK119Ub affects the expression of MCP-1 and TGF-beta1 and their regulation by Angiotensin II receptor subtypes remains unknown. In the current study, we aimed to study the effect of Angiotensin II receptors' blockade on the macrophage infiltration and histone modifications occurring at the promoter region of Mcp1 and Tgfb1in high fat diet fed and low dose streptozotocin treated male Wistar rats. Hereby, we present the first report delineating a distinct link between H2AK119Ub and macrophage infiltration and fibrosis i.e. the enrichment of H2AUb at Mcp1 and Tgfb1 promoter region was found to reduce drastically in the T2DN which could be significantly reversed by Telmisartan and was further elevated by PD123319. We could conclude that the Angiotensin II mediated macrophage infiltration in T2DN is regulated at least partially by H2AK119Ub through both AT1 and AT2 receptors, which to the best of our knowledge, presents the first report for the regulation of Mcp1 by H2AK119Ub. Thus an approach targeting AT1R blockade and AT2R activation accompanied by an epigenetic modulator may be more suitable to ameliorate the macrophage infiltration and fibrosis associated with T2DN. PMID- 27693082 TI - Culture and nonverbal expressions of empathy in clinical settings: A systematic review. AB - OBJECTIVE: To conduct a systematic review of studies examining how culture mediates nonverbal expressions of empathy with the aim to improve clinician cross cultural competency. METHODS: We searched three databases for studies of nonverbal expressions of empathy and communication in cross-cultural clinical settings, yielding 16,143 articles. We examined peer-reviewed, experimental or observational articles. Sixteen studies met inclusion criteria. RESULTS: Nonverbal expressions of empathy varied across cultural groups and impacted the quality of communication and care. Some nonverbal behaviors appeared universally desired and others, culturally specific. Findings revealed the impact of nonverbal communication on patient satisfaction, affective tone, information exchange, visit length, and expression decoding during cross-cultural clinical encounters. Racial discordance, patients' perception of physician racism, and physician implicit bias are among factors that appear to influence information exchange in clinical encounters. CONCLUSION: Culture-based norms impact expectations for specific nonverbal expressions within patient-clinician dyads. Nonverbal communication plays a significant role in fostering trusting provider patient relationships, and is critical to high quality care. PRACTICE IMPLICATIONS: Medical education should include training in interpretation of nonverbal behavior to optimize empathic cross-cultural communication and training efforts should accommodate norms of local patient populations. These efforts should reduce implicit biases in providers and perceived prejudice in patients. PMID- 27693083 TI - "Forewarned and forearmed": Long-term childhood cancer survivors' and parents' information needs and implications for survivorship models of care. AB - OBJECTIVE: This mixed-method study assessed 1) survivors' and parents' information needs; and 2) associations between unmet information needs and clinical and socio-demographic characteristics. METHODS: Stage 1: CCS and parents of CCS, >5years post-diagnosis completed a questionnaire on information needs, overall health and perceived risk. Predictors for unmet information needs were assessed by multivariable regression. Stage 2: participants were interviewed in depth on these topics. RESULTS: Questionnaires were completed by 485 participants comprising 322 survivors (mean age: 26.7years, SD=7.9; time since diagnosis: 19.7years, SD=8.8) and 163 parents (child age: 12.9years, SD=2.4; time since diagnosis: 9.7years, SD=2.3), and complemented by 70 interviews. Survivors reported unmet information needs about late effects (57.5%) and parents for fertility issues (62.5%). Survivors had more unmet needs for medical information whereas parents had significantly more regarding sexual issues and lifestyle. Being a parent (p=0.001), dissatisfaction with follow-up care (p=0.003), lower overall health (p=0.014), higher perceived risk of late effects (p<0.001), and greater anxiety/depression (p<0.001) were significantly associated with more unmet needs. CONCLUSION: Unmet information needs were common for survivors and parents of CCS. PRACTICE IMPLICATIONS: Future efforts towards tailoring information on potential late effects, healthy lifestyles and follow-up care may help to address unmet information needs. PMID- 27693084 TI - Parenting a child with chronic illness as they transition into adulthood: A systematic review and thematic synthesis of parents' experiences. AB - OBJECTIVE: To understand how parents view and experience their role as their child with a long-term physical health condition transitions to adulthood and adult healthcare services. METHODS: Five databases were systematically searched for qualitative articles examining parents' views and experiences of their child's healthcare transition. Papers were quality assessed and thematically synthesised. RESULTS: Thirty-two papers from six countries, spanning a 17-year period were included. Long-term conditions were diverse. Findings indicated that parents view their child's progression toward self-care as an incremental process which they seek to facilitate through up-skilling them in self-management practices. Parental perceptions of their child's readiness, wellness, competence and long-term condition impacted on the child' progression to healthcare autonomy. A lack of transitional healthcare and differences between paediatric and adult services served as barriers to effective transition. Parents were required to adjust their role, responsibilities and behaviour to support their child's growing independence. CONCLUSION: Parents can be key facilitators of their child's healthcare transition, supporting them to become experts in their own condition and care. To do so, they require clarification on their role and support from service providers. PRACTICE IMPLICATIONS: Interventions are needed which address the transitional care needs of parents as well as young people. PMID- 27693085 TI - Winds of Change in Higher Education. AB - Recent developments confirm predictions by the IEEE that Massive Open Online Courses (MOOCs) will have extensive impact on the future landscape of higher education. New degree structures are being introduced and awarding of verified MOOC credentials is becoming more widespread, as is recognition of MOOC credits by universities and employers. The question is whether this disruptive influence is being sufficiently used as an incentive for re-evaluation of standard practices and for driving strategic change in higher education. PMID- 27693086 TI - Fraud Not a Primary Cause of Irreproducible Results: A Reply to Clark et al. PMID- 27693087 TI - Cognitive Phenotypes and the Evolution of Animal Decisions. AB - Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The 'judgment and decision-making' (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as 'cognitive phenotypes'. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical approaches to characterize them as evolvable traits. PMID- 27693088 TI - Immune checkpoint inhibitors for nonsmall cell lung cancer treatment. AB - Immune checkpoint inhibition with blocking antibodies that target cytotoxic T lymphocyte antigen-4 (CTLA-4) and the programmed cell death protein 1 (PD-1) pathway [PD-1/programmed death-ligand 1 (PD-L1)] have demonstrated promise in a variety of malignancies. While ipilimumab has been approved as a CTLA-4 blocking antibody by the US Food and Drug Administration for the treatment of advanced melanoma, it is still not approved for lung cancer treatment. In contrast, nivolumab and pembrolizumab, both PD-1 blocking antibodies, have been approved for second-line treatment of nonsmall cell lung cancer in 2015 because of their high potency and long-lasting effects in some patient subgroups. Other PD-1 and PD-L1 monoclonal antibodies are also in active development phase. Treatment with such immune checkpoint inhibitors is associated with a unique pattern of immune related adverse events or side effects. Combination approaches involving CTLA-4 and PD-1/PD-L1 blockade or checkpoint inhibitors with chemotherapy or radiotherapy are being investigated to determine whether they may enhance the efficacy of treatment. Despite many challenges ahead, immunotherapy with checkpoint inhibitors has already become a new and important treatment modality for lung cancer in the last decade following the discovery of targeted therapy. PMID- 27693089 TI - Contribution of magnetic resonance imaging in lung cancer imaging. AB - Lung cancer is the leading cause of cancer death worldwide. Prognosis and treatment outcomes are known to be related to the disease stage at the time of diagnosis. Therefore, an accurate assessment of the extent of disease is critical to determine the most appropriate therapy. Currently available imaging modalities for diagnosis and follow-up consist of morphological and functional imaging. Morphological investigations are mainly performed with CT-scan and in some cases with MRI. In this review, we describe the contribution of MRI in lung cancer staging focusing on solid pulmonary nodule characterization and TNM staging assessment using chest and whole-body MRI examinations, detailing in each chapter current recommendations and future developments. PMID- 27693090 TI - Evaluation of lung tumor response to therapy: Current and emerging techniques. AB - Lung tumor response to therapy may be evaluated in most instances by morphological criteria such as RECIST 1.1 on computed tomography (CT) or magnetic resonance imaging (MRI). However, those criteria are limited because they are based on tumoral dimensional changes and do not take into account other morphologic criteria such as density evaluation, functional or metabolic changes that may occur following conventional or targeted chemotherapy. New techniques such as dual-energy CT, PET-CT, MRI including diffusion-weighted MRI has to be considered into the new technical armamentarium for tumor response evaluation. Integration of all informations provided by the different imaging modalities has to be integrated and represents probably the future goal of tumor response evaluation. The aim of the present paper is to review the current and emerging imaging criteria used to evaluate the response of therapy in the field of lung cancer. PMID- 27693091 TI - Outcome of metastatic urothelial carcinoma treated by systemic chemotherapy: Prognostic factors based on real-world clinical practice in Japan. AB - AIM: To clarify prognostic factors of metatstatic urothelial carcinoma treated by systemic chemotherapy in real-world clinical practice in the Japanese population. MATERIALS AND METHODS: A total of 228 patients with metastatic urothelial carcinoma undergoing systemic chemotherapy between 2000 and 2013 were included in the present multi-institutional study. The gemcitabine plus cisplatin regimen was administered as first-line chemotherapy to 131 patients, whereas methotrexate, vinblastine, doxorubicin, and cisplatin or its modified regimen was given to 71 patients. Of the 228 patients, 119 received at least 2 different regimens and 22 underwent resection of metastases (metastasectomy). Multivariate survival analysis was performed using the Cox proportional hazards model. The characteristics included were age, sex, Eastern Cooperative Oncology Group performance status (PS), primary site, pathology of primary site, hemoglobin levels, lactate dehydrogenase levels, C-reactive protein levels, corrected calcium levels, estimated glomerular filtration rate levels, history of prior chemotherapy, metastatic sites, resection of primary site, number of metastatic organs, and metastasectomy. RESULTS: The median overall survival (OS) time was 17 months. On multivariate analysis, female sex, good Eastern Cooperative Oncology Group PS at presentation, hemoglobin level>=10g/dl, and single organ metastasis were significant independent predictors of prolonged OS. For the survival effect of metastasectomy, the median OS time of the 22 patients with metastasectomy was 53 months, which was significantly longer when compared with patients not undergoing metastasectomy (15mo). After adjustment for the 4 aforementioned prognostic factors, metastasectomy still remained significant (hazard ratio: 0.364, P = 0.0008). CONCLUSIONS: Female sex, more favorable PS at presentation, hemoglobin level>10g/dl, and single organ metastasis were favorable prognostic factors. In addition, metastasectomy was associated with long-term disease control. PMID- 27693093 TI - Complete genome sequence of Bacillus thuringiensis serovar alesti BGSC 4C1, a typical strain with toxicity to Lepidoptera insects. AB - Bacillus thuringiensis serovar alesti was used to control caterpillars from 1970s. Here we reported the complete genome of BGSC 4C1, the type strain of this serovar. It has a circular chromosome and six plasmids. The largest plasmid pBMB267 contains five insecticidal crystal protein genes (two copies of cry1Ae, cry1Gb, cry2Ab, and a novel cry1M-type gene) and three vegetative insecticidal protein genes (a novel binary toxin gene operon vip1-vip2 and vip3Aa). Besides, the strain also has many genes encodeing virulence factors, and some secondary metabolite biosynthetic gene clusters involved in synthesis of antimicrobial peptides and bacteriocins. In addition, there is a poly gamma-glutamate synthesis gene cluster, whose product is a candidate to control inflammasome-mediated disorders and potential in many other fields. PMID- 27693092 TI - Combinatorial deletions of glgC and phaCE enhance ethanol production in Synechocystis sp. PCC 6803. AB - Synechocystis sp. PCC 6803 is an attractive host for bio-ethanol production. In the present study, a nitrogen starvation approach was applied on an ethanol producing strain for inhibiting the growth, since ethanol production competes with the cell growth. The effect of gene deletions in the glycogen and polyhydroxybutyrate (PHB) synthesis pathways was investigated. Measurements of intracellular glycogen and PHB revealed that the glycogen was accumulated under the nitrogen starvation condition and the gene deletion of glycogen synthesis pathway caused the accumulation of PHB. The ethanol producing strain harboring deletions for both the glycogen and the PHB synthesis pathways (DeltaglgCDeltaphaCE/EtOH) produced ethanol at the specific rate of 240mgg (dry cell weight)-1 day-1 under the nitrogen starvation condition. In a high cell density culture (OD730=50) using this DeltaglgCDeltaphaCE/EtOH strain, the ethanol production rates were 1.08 and 2.01gL-1 day-1 under light conditions of 40 and 80MUmolm-2s-1, respectively.

PMID- 27693095 TI - Clinical practice guidelines for vitamin D in the United Arab Emirates. AB - In the UAE and the Gulf region in general, there are several intricate public health issues in the context of vitamin D deficiency that needs to be addressed. Changes in lifestyle such as diet, lack of exercise, cultural habits, avoiding sun exposure due to excessive heat, and other risk factors predispose those who live in GULF countries, such as Emiratis likely to becoming vitamin D deficient. Consequently, the prevalence of vitamin D deficiency is high, and new guidelines are needed to overcome this major public health issue. Peer-reviewed papers related to guidelines and those vitamin D-related papers relevant to the Middle Eastern region were extracted from multiple research databases using key words according to the general guidelines from the Preferred Reporting Items for Systematic Analysis. This guideline was prepared focusing on the United Arab Emirate and the Gulf populations, to overcome the high incidence of vitamin D deficiency and to improve overall health. We recommend the following vitamin D supplementations for different groups of people: (A) Breastfed infants supplement with 400 IU/day up to age 6 months, and 400-600 IU/day between 6 and 12 months, depending on daily intake of total vitamin D and sun exposure; (B) for children and adolescents of age 1-18 years supplement with 600-1000 IU/day depending on the body weight; (C) adults greater than 18 years', supplementation with 1000 2000 IU/day is recommended, while, (D) the elderly (over 65 years) should be supplemented with 2000 IU/day, throughout the year; (E) pregnant and breast feed women, 2000 IU/day from the first trimester of pregnancy. (F) Premature infants, supplementation of 400-800 IU/daystart from the first days of life. (G) For obese, individuals and those with metabolic syndrome, supplementation of 2000 IU/day (H) For individuals with dark skin complexions and for night workers, supplementation of 1000-2000 IU/day (25-50MUg/day), throughout the year, depending on body weight. The goal of supplementation is to achieve and longer term maintenance of serum 25(OH)D concentration of 30-50ng/mL. PMID- 27693096 TI - Clinical significance of serum carbohydrate antigen 19.9 and duke pancreatic monoclonal antigen type 2 for the prediction of hematogenous metastases in patients with pancreatic ducal adenocarcinoma. AB - OBJECTIVES: The aim of the present study was to investigate the effectiveness of serum carbohydrate antigen (CA) 19.9 and duke pancreatic monoclonal antigen type 2 (DUPAN-2) levels in the prediction of early hematogenous metastases and as indicators of neoadjuvant therapy in patients with pancreatic ductal adenocarcinoma (PDAC). METHODS: Of the 293 enrolled PDAC patients, 61 had hematogenous metastases at the initial evaluation. One hundred and twenty patients without metastases underwent surgical resection. Of the 120 patients who underwent surgical resection, 45 underwent preoperative treatment and 29 developed early hematogenous metastases within 1 year after the surgery. In patients who underwent preoperative therapy, serum CA 19.9 and DUPAN-2 levels were measured within 2 weeks before the preoperative therapy and the subsequent surgery. RESULTS: The elevated serum CA 19.9 and DUPAN-2 levels were significantly associated with hematogenous metastasis at initial evaluation and early hematogenous metastasis after surgery. The rate of early hematogenous metastasis and overall survival (OS) in patients with high CA 19.9 and/or high DUPAN-2 (CA 19.9 > 200 U/mL and/or DUPAN-2 >300 U/mL) were 46.3% and 18 months, respectively, whereas the metastatic rate and OS in patients with low CA 19.9 and DUPAN-2 were 12.7% and 37.5 months, respectively. Furthermore, in patients with high CA 19.9 and/or high DUPAN-2, preoperative therapy significantly reduced the rate of early hematogenous metastasis and prolonged the OS. CONCLUSIONS: Serum CA 19.9 and DUPAN-2 levels are useful predictors of early hematogenous metastasis and indicators for effectiveness of neoadjuvant therapy in PDAC patients. PMID- 27693097 TI - Pain assessment in chronic pancreatitis: A comparative review of methods. AB - BACKGROUND: Patients with chronic pancreatitis (CP) frequently report chronic abdominal pain that adversely impacts their quality of life. Assessment of pain in CP is required for clinical management and clinical studies. International consensus guidelines recognized a lack of specific and validated pain assessment tools for CP. Therefore, the aim of this systematic review is to identify and compare all clinical studies that assessed pain in the context of a treatment for pain in CP. METHODS: A systematic literature search was performed in PubMed, Cochrane Library and Ovid MEDLINE. The search identified all intervention studies for pain in CP and the pain assessment tools used based on pre-defined inclusion and exclusion criteria. RESULTS: Of 341 articles identified, 137 studies were included. Pain assessment tools were both general and CP-specific. The latter were used in only 22 (16%) studies. Despite recommendations the aspects of pain assessed were limited and variable between tools. Validation of these tools in CP patients was limited to quality of life measures. None of the pain assessment tools evaluated duration of pain and postprandial pain. CONCLUSIONS: There are no published pain assessment tools for CP that includes all relevant aspects of pain. There is the need to develop a comprehensive and validated pain assessment tool for patients with CP to standardised pain assessment, identify likely underlying pain mechanisms, help select appropriate treatments, report outcomes from interventions, improve clinical communication and aid the allocation of patients to clinical trials. PMID- 27693098 TI - Serratus anterior and trapezius muscle activity during knee push-up plus and knee plus exercises performed on a stable, an unstable surface and during sling suspension. AB - OBJECTIVES: Push-up plus variations are commonly prescribed to clients during shoulder rehabilitation. The purpose of this study was to compare electromyographic (EMG) activities of the serratus anterior (SA), upper (UT), and lower trapezius (LT) during a knee push-up plus and knee-plus exercise performed on various surfaces. STUDY DESIGN: Within-subjects Repeated-Measure Design. PARTICIPANTS: 19 healthy, young female participants performed both exercises on a stable and unstable surface and during sling-suspension. OUTCOME MEASURES: Surface EMG activities were recorded and average amplitudes were presented as a percentage of the maximal voluntary contraction. A two-way repeated-measures ANOVA was performed to determine differences in activity for each muscle. RESULTS: SA showed no significant differences between exercises and was independent of the base of support (p > 0.05). Muscle activity of UT (95% CI [1.2, 1.4]) and LT (95% CI [2.4, 3.5]) showed slightly greater values when performing the knee push-up plus compared to the knee-plus exercise. CONCLUSIONS: The isolated protraction of the shoulder girdle in a kneeling position is as sufficient as the push-up plus in activating the SA selectively. Therefore, we recommended this exercise for clients who are unable to perform an entire push-up or should avoid detrimental stress on the shoulder joint.

AB - OBJECTIVES: This study aimed to explore the differences in the magnitude of movement variability and strategies utilized during an unanticipated cut task between players with and without a history of groin pain. DESIGN: Cross-sectional design. SETTING: Biomechanics laboratory. PARTICIANTS: Male Australian football players with (HISTORY; n = 7) or without (CONTROL; n = 10) a history of groin pain. OUTCOME MEASURES: Three-dimensional ground reaction forces (GRF) and kinematics were recorded during 10 successful trials of an unanticipated cut task, and isokinetic hip adduction and abduction strength. Between-group differences were determined using independent-samples t-tests and the coefficient of variation (CV). RESULTS: Key substantial between-group differences identified were that the HISTORY group displayed decreased knee flexion and hip internal rotation, increased knee internal rotation and T12-L1 right rotation, and higher GRFs during the cut task. They also utilized three invariant systems (ankle, knee and T12-L1 joints), while being connected by a segment (hip and L5-S1 joints) that displayed increased lumbopelvic movement during the cut task, and decreased adductor muscle strength. CONCLUSION: This identifies the need for clinical management of the lower limb and thoracic segment to improve functional movement patterns in athletes with a history of a groin injury. PMID- 27693101 TI - Heart-rate deceleration predicting the determination of costly punishment: Implications for its involvement in cognitive effort expended in overriding self interest. AB - Previous studies have investigated which biological markers predict the decision to reject unfair monetary offers, termed costly punishment, in the ultimatum game (UG). One study showed that a phasic deceleratory response in heart rate (HR) is evoked in the responder more readily by offers that will be rejected than by offers that will be accepted. However, owing to the paucity of supporting evidence, it remains unclear whether and why HR deceleration can predict the decisions of UG responders. In this paper, we report two separate studies (Study 1 and Study 2) using modified versions of the UG to explore factors modulating HR deceleration. In Study 1, as well as unfair offers, fair offers induced greater HR deceleration when responders were forced to reject offers compared to when they were forced to accept offers. In Study 2, a high rejection rate for very unfair offers was sustained, regardless of the size of the offers, but HR deceleration was increased for unfair but large offers, relative to unfair, small offers. Moreover, HR deceleration was associated with the rejection of large offers. However, across the two studies, HR deceleration did not simply vary depending on unfairness. These findings support the possibility that HR decelerates as a function of cognitive load in determining costly punishment. PMID- 27693100 TI - Diagnostic validity of physical examination tests for common knee disorders: An overview of systematic reviews and meta-analysis. AB - INTRODUCTION: More evidence on diagnostic validity of physical examination tests for knee disorders is needed to lower frequently used and costly imaging tests. OBJECTIVE: To conduct a systematic review of systematic reviews (SR) and meta analyses (MA) evaluating the diagnostic validity of physical examination tests for knee disorders. METHODS: A structured literature search was conducted in five databases until January 2016. Methodological quality was assessed using the AMSTAR. RESULTS: Seventeen reviews were included with mean AMSTAR score of 5.5 +/ 2.3. Based on six SR, only the Lachman test for ACL injuries is diagnostically valid when individually performed (Likelihood ratio (LR+):10.2, LR-:0.2). Based on two SR, the Ottawa Knee Rule is a valid screening tool for knee fractures (LR :0.05). Based on one SR, the EULAR criteria had a post-test probability of 99% for the diagnosis of knee osteoarthritis. Based on two SR, a complete physical examination performed by a trained health provider was found to be diagnostically valid for ACL, PCL and meniscal injuries as well as for cartilage lesions. CONCLUSION: When individually performed, common physical tests are rarely able to rule in or rule out a specific knee disorder, except the Lachman for ACL injuries. There is low-quality evidence concerning the validity of combining history elements and physical tests.

AB - Stimulus-locked averaged event-related potentials (ERPs) are among the most frequently used signals in Cognitive Neuroscience. However, the late, cognitive or endogenous ERP components are often variable in latency from trial to trial in a component-specific way, compromising the stability assumption underlying the averaging scheme. Here we show that trial-to-trial latency variability of ERP components not only blurs the average ERP waveforms, but may also attenuate existing or artificially induce condition effects in amplitude. Hitherto this problem has not been well investigated. To tackle this problem, a method to measure and compensate component-specific trial-to-trial latency variability is required. Here we first systematically analyze the problem of single trial latency variability for condition effects based on simulation. Then, we introduce a solution by applying residue iteration decomposition (RIDE) to experimental data. RIDE separates different clusters of ERP components according to their time locking to stimulus onsets, response times, or neither, based on an algorithm of iterative subtraction. We suggest to reconstruct ERPs by re-aligning the component clusters to their most probable single trial latencies. We demonstrate that RIDE-reconstructed ERPs may recover amplitude effects that are diminished or exaggerated in conventional averages by trial-to-trial latency jitter. Hence, RIDE-corrected ERPs may be a valuable tool in conditions where ERP effects may be compromised by latency variability. PMID- 27693105 TI - Clinical Islet Xenotransplantation: A Step Forward. PMID- 27693103 TI - Bone Graft Prefabrication Following the In Vivo Bioreactor Principle. AB - Large bone defect treatment represents a great challenge due to the difficulty of functional and esthetic reconstruction. Tissue-engineered bone grafts created by in vitro manipulation of bioscaffolds, seed cells, and growth factors have been considered potential treatments for bone defect reconstruction. However, a significant gap remains between experimental successes and clinical translation. An emerging strategy for bridging this gap is using the in vivo bioreactor principle and flap prefabrication techniques. This principle focuses on using the body as a bioreactor to cultivate the traditional triad (bioscaffolds, seed cells, and growth factors) and leveraging the body's self-regenerative capacity to regenerate new tissue. Additionally, flap prefabrication techniques allow the regenerated bone grafts to be transferred as prefabricated bone flaps for bone defect reconstruction. Such a strategy has been used successfully for reconstructing critical-sized bone defects in animal models and humans. Here, we highlight this concept and provide some perspective on how to translate current knowledge into clinical practice. PMID- 27693104 TI - Characterization of a 2016 Clinical Isolate of Zika Virus in Non-human Primates. AB - Animal models are critical to understand disease and to develop countermeasures for the ongoing epidemics of Zika virus (ZIKV). Here we report a non-human primate model using a 2016 contemporary clinical isolate of ZIKV. Upon subcutaneous inoculation, rhesus macaques developed fever and viremia, with robust excretion of ZIKV RNA in urine, saliva, and lacrimal fluid. Necropsy of two infected animals revealed that systematic infections involving central nervous system and visceral organs were established at the acute phrase. ZIKV initially targeted the intestinal tracts, spleen, and parotid glands, and retained in spleen and lymph nodes till 10days post infection. ZIKV-specific immune responses were readily induced in all inoculated animals. The non-human primate model described here provides a valuable platform to study ZIKV pathogenesis and to evaluate vaccine and therapeutics.

AB - Thrombotic thrombocytopenic purpura (TTP) is a disease caused by excessive platelet thrombi and multisystem vasculopathy. We report a young patient with refractory TTP who has developed multiple multifocal cerebral microbleeds on his brain magnetic resonance imaging scans. TTP-associated thrombotic microangiopathy resulting in diffuse microthrombi formation in the microcirculation and hypoperfusion might be an underlying etiology. PMID- 27693107 TI - e-NIHSS: an Expanded National Institutes of Health Stroke Scale Weighted for Anterior and Posterior Circulation Strokes. AB - BACKGROUND: The National Institutes of Health Stroke Scale (NIHSS) is the most widespread clinical scale used in patients presenting with acute stroke. The merits of the NIHSS include simplicity, quickness, and agreement between clinicians. The clinical evaluation on posterior circulation stroke remains still a limit of NIHSS. METHODS: We assessed the application of a new version of NIHSS, the e-NIHSS (expanded NIHSS), adding specific elements in existing items to explore signs/symptoms of a posterior circulation stroke. A total of 22 consecutive patients with suspected vertebrobasilar stroke were compared with 25 patients with anterior circulation stroke using NIHSS and e-NIHSS. RESULTS: We compared the NIHSS and e-NIHSS scores obtained by the 2 examiners, in patients with posterior circulation infarct (POCI), using the Wilcoxon test. Patients with POCI evaluated with e-NIHSS had an average of 2 points higher than patients evaluated with classical NIHSS. The difference was statistically significant (P < .05), weighted by the new expanded items. CONCLUSIONS: The NIHSS is a practical scale model, with high reproducibility between trained, different examiners, focused on posterior circulation strokes, with the same total score and number of items of the existing NIHSS. The e-NHISS could improve the sensitivity of NIHSS in posterior circulation stroke and could have an impact on clinical trials, as well as on outcomes. Further studies are needed to investigate a larger number of patients and the correlation between the e-NIHSS score and neuroimaging findings. PMID- 27693108 TI - A Comparison of Reinforcement Based Treatment (RBT) versus RBT plus Recovery Housing (RBTRH). AB - OBJECTIVES: Reinforcement-based treatment (RBT) plus recovery housing (RBTRH) improves outcomes for individuals with opioid use disorders. No studies have examined the efficacy of RBT in the absence of abstinent-contingent housing. METHODS: We compared highly similar participants from a study of outpatient RBT (RBT, n=55) and the RBTRH (n=80) arm of a randomized trial wherein participants received abstinent-contingent payment for recovery housing sponsored by the research program. Abstinence and employment outcomes were assessed at one, three, and six months. Regression was used to identify predictors of abstinence. Sensitivity analyses explored the impact of housing on outcomes. RESULTS: RBT and RBTRH participants had similar abstinence and employment outcomes. Predictors of abstinence in the sample included recovery housing residence and employment. However, a distinct RBT sub-group emerged, as 33% of the sample accessed self-pay RH (RBTSPRH). Sensitivity analyses compared the two RH groups (self-pay and program-supported) to RBT outpatient treatment (RBT). The RBTSPRH and RBTRH groups had similar abstinence outcomes, and both groups had superior abstinence outcomes compared to RBT. The RBTSPRH group had the most sustained effects relative to RBT, including higher abstinence rates, and more favorable employment outcomes at six months (ps<.05). The RBTSPRH group reported more days of employment compared to both the RBT and RBTRH groups at three months (ps<.05). CONCLUSIONS: Findings highlight the importance of recovery housing for promoting improved outcomes among RBT participants. Research is needed to explore the aspects of recovery housing versus outpatient treatment that are associated with improved outcomes in the population. PMID- 27693109 TI - Lower cerebral blood flow is associated with impairment in multiple cognitive domains in Alzheimer's disease. AB - INTRODUCTION: We examined the association between decreased cerebral blood flow (CBF) and cognitive impairment in Alzheimer's disease (AD), mild cognitive impairment (MCI), and subjective cognitive decline (SCD). METHODS: We included 161 AD, 95 MCI, and 143 SCD patients from the Amsterdam Dementia Cohort. We used 3-T pseudo-continuous arterial spin labeling to estimate whole-brain and regional partial volume-corrected CBF. Neuropsychological tests covered global cognition and five cognitive domains. Associations were investigated using linear regression analyses. RESULTS: In the whole sample, reduced overall and regional CBF was associated with impairment in all cognitive domains. We found significant interactions between diagnosis and CBF for language and between diagnosis and parietal CBF for global cognition and executive functioning. Stratification showed that decreased CBF was associated with worse performance in AD patients but not in MCI or SCD. DISCUSSION: Our results suggest that CBF may have potential as a functional marker of disease severity. PMID- 27693110 TI - Percutaneous balloon mitral valvuloplasty and closure of the left atrial appendage: Synergy of two procedures in one percutaneous intervention. AB - Mitral stenosis (MS) is frequently associated with the development of atrial fibrillation (AF) as a consequence of hemodynamic and inflammatory changes in the left atrium. Both conditions predispose to thrombus formation, with frequent involvement of the left atrial appendage (LAA), and consequent increase in the incidence of systemic thromboembolic events. Percutaneous mitral valvuloplasty (PMV) reduces the risk of thromboembolism in patients with significant mitral stenosis. Percutaneous LAA closure is also associated with a reduction in thromboembolic risk in patients with AF, but there are no data regarding the use of this technique in patients with significant mitral valve disease. We report the case of a 57-year-old-woman with significant MS and permanent AF, in New York Heart Association functional class II, who despite adequate oral anticoagulation with acenocoumarol, presented several clinical episodes of systemic thromboembolism in the last four years. It was decided to perform a combined percutaneous procedure, including both PMV and percutaneous LAA closure with the Amplatzer Cardiac Plug device. No significant acute complications occurred and the patient was discharged on indefinite treatment with acenocoumarol associated with aspirin 100 mg/d for three months. After a one-year follow-up, there have been no new embolic episodes or other complications. PMID- 27693111 TI - Abnormal electrocardiographic findings in athletes: Correlation with intensity of sport and level of competition. AB - INTRODUCTION: Athletes can exhibit abnormal electrocardiogram (ECG) phenotypes that require further evaluation prior to competition. These are apparently more prevalent in high-intensity endurance sports. The purpose of this study was to assess the association between ECG findings in athletes and intensity of sport and level of competition. METHODS: A cohort of 3423 competitive athletes had their ECGs assessed according to the Seattle criteria (SC). The presence of abnormal ECGs was correlated with: (1) intensity of sport (low/moderate vs. at least one high static or dynamic component); (2) competitive level (regional vs. national/international); (3) training volume (<=20 vs. >20 hours/week); (4) type of sport (high dynamic vs. high static component). The same endpoints were studied according to the 'Refined Criteria' (RC). RESULTS: Abnormal ECGs according to the SC were present in 225 (6.6%) athletes, more frequently in those involved in high-intensity sports (8.0% vs. 5.4%; p=0.002), particularly in dynamic sports, and competing at national/international level (7.1% vs. 4.9%; p=0.028). Training volume was not significantly associated with abnormal ECGs. By multivariate analysis, high-intensity sport (OR 1.55, 1.18-2.03; p=0.002) and national/international level (OR 1.50, 95% CI 1.04-2.14; p=0.027) were independent predictors of abnormal ECGs, and these variables, when combined, doubled the prevalence of this finding. According to the RC, abnormal ECGs decreased to 103 (3.0%), but were also more frequent in high-intensity sports (4.2% vs. 2.0%; p<0.001). CONCLUSIONS: There is a positive correlation between higher intensity of sports and increased prevalence of ECG abnormalities. This relationship persists with the use of more restrictive criteria for ECG interpretation, although the number of abnormal ECGs is lower.

PMID- 27693114 TI - TonB-dependent ligand trapping in the BtuB transporter. AB - TonB-dependent transporters are beta-barrel outer membrane proteins occluded by a plug domain. Upon ligand binding, these transporters extend a periplasmic motif termed the TonB box. The TonB box permits the recruitment of the inner membrane protein complex TonB-ExbB-ExbD, which drives import of ligands in the cell periplasm. It is unknown precisely how the plug domain is moved aside during transport nor have the intermediate states between TonB recruitment and plug domain movement been characterized biochemically. Here we employ nanodiscs, native gel electrophoresis, and scintillation proximity assays to determine the binding kinetics of vitamin B12 to BtuB. The results show that ligand-bound BtuB recruits a monomer of TonB (TonB?1-31), which in turn increases retention of vitamin B12 within the transporter. The TonB box and the extracellular residue valine 90 that forms part of the vitamin B12 binding site are essential for this event. These results identify a novel step in the TonB-dependent transport process. They show that TonB binding to BtuB trap the ligand, possibly until the ExbB-ExbD complex is activated or recruited to ensure subsequent transport. PMID- 27693115 TI - 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) increases necroinflammation and hepatic stellate cell activation but does not exacerbate experimental liver fibrosis in mice. AB - 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a persistent environmental contaminant and high-affinity ligand for the aryl hydrocarbon receptor (AhR). Increasing evidence indicates that AhR signaling contributes to wound healing, which involves the coordinated deposition and remodeling of the extracellular matrix. In the liver, wound healing is attributed to the activation of hepatic stellate cells (HSCs), which mediate fibrogenesis through the production of soluble mediators and collagen type I. We recently reported that TCDD treatment increases the activation of human HSCs in vitro. The goal of this study was to determine how TCDD impacts HSC activation in vivo using a mouse model of experimental liver fibrosis. To elicit fibrosis, C57BL6/male mice were treated twice weekly for 8weeks with 0.5ml/kg carbon tetrachloride (CCl4). TCDD (20MUg/kg) or peanut oil (vehicle) was administered once a week during the last 2weeks. Results indicate that TCDD increased liver-body-weight ratios, serum alanine aminotransferase activity, and hepatic necroinflammation in CCl4-treated mice. Likewise, TCDD treatment increased mRNA expression of HSC activation and fibrogenesis genes, namely alpha-smooth muscle actin, desmin, delta-like homolog 1, TGF-beta1, and collagen type I. However, TCDD treatment did not exacerbate fibrosis, nor did it increase the collagen content of the liver. Instead, TCDD increased hepatic collagenase activity and increased expression of matrix metalloproteinase (MMP)-13 and the matrix regulatory proteins, TIMP-1 and PAI-1. These results support the conclusion that TCDD increases CCl4-induced liver damage and exacerbates HSC activation, yet collagen deposition and the development of fibrosis may be limited by TCDD-mediated changes in extracellular matrix remodeling. PMID- 27693116 TI - Epirubicin With Cyclophosphamide Followed by Docetaxel With Trastuzumab and Bevacizumab as Neoadjuvant Therapy for HER2-Positive Locally Advanced Breast Cancer or as Adjuvant Therapy for HER2-Positive Pathologic Stage III Breast Cancer: A Phase II Trial of the NSABP Foundation Research Group, FB-5. AB - BACKGROUND: The purpose of this study was to determine the cardiac safety and clinical activity of trastuzumab and bevacizumab with docetaxel after epirubicin with cyclophosphamide (EC) in patients with HER2-positive locally advanced breast cancer (LABC) or pathologic stage 3 breast cancer (PS3BC). PATIENTS AND METHODS: Patients received every 3 week treatment with 4 cycles of EC (90/600 mg/m2) followed by 4 cycles of docetaxel (100 mg/m2). Targeted therapy with standard dose trastuzumab with bevacizumab 15 mg/kg was given for a total of 1 year. Coprimary end points were (1) rate of cardiac events (CEs) in all patients defined as clinical congestive heart failure with a significant decrease in left ventricular ejection fraction or cardiac deaths; and (2) pathologic complete response (pCR) in breast and nodes in the neoadjuvant cohort. An independent cardiac review panel determined whether criteria for a CE were met. RESULTS: A total of 105 patients were accrued, 76 with LABC treated with neoadjuvant therapy and 29 with PS3BC treated with adjuvant therapy. Median follow-up was 59.2 months. Among 99 evaluable patients for cardiac safety, 4 (4%; 95% confidence interval [CI], 1.1%-10.0%) met CE criteria. The pCR percentage in LABC patients was 46% (95% CI, 34%-59%). Five-year recurrence-free survival (RFS) and overall survival (OS) for all patients was 79.9% and 90.8%, respectively. CONCLUSION: The regimen met predefined criteria for activity of interest with an acceptable rate of CEs. Although the pCR percentage was comparable with chemotherapy regimens with trastuzumab alone the high RFS and OS are of interest in these high-risk populations. PMID- 27693117 TI - Distinct and overlapping DNMT1 interactions with multiple transcription factors in erythroid cells: Evidence for co-repressor functions. AB - DNMT1 is the maintenance DNA methyltransferase shown to be essential for embryonic development and cellular growth and differentiation in many somatic tissues in mammals. Increasing evidence has also suggested a role for DNMT1 in repressing gene expression through interactions with specific transcription factors. Previously, we identified DNMT1 as an interacting partner of the TR2/TR4 nuclear receptor heterodimer in erythroid cells, implicated in the developmental silencing of fetal beta-type globin genes in the adult stage of human erythropoiesis. Here, we extended this work by using a biotinylation tagging approach to characterize DNMT1 protein complexes in mouse erythroleukemic cells. We identified novel DNMT1 interactions with several hematopoietic transcription factors with essential roles in erythroid differentiation, including GATA1, GFI 1b and FOG-1. We provide evidence for DNMT1 forming distinct protein subcomplexes with specific transcription factors and propose the existence of a "core" DNMT1 complex with the transcription factors ZBP-89 and ZNF143, which is also present in non-hematopoietic cells. Furthermore, we identified the short (17a.a.) PCNA Binding Domain (PBD) located near the N-terminus of DNMT1 as being necessary for mediating interactions with the transcription factors described herein. Lastly, we provide evidence for DNMT1 serving as a co-repressor of ZBP-89 and GATA1 acting through upstream regulatory elements of the PU.1 and GATA1 gene loci. PMID- 27693119 TI - Early onset fetal growth restriction. AB - Fetal growth restriction remains a challenging entity with significant variations in clinical practice around the world. The different etiopathogenesis of early and late fetal growth restriction with their distinct progression of fetal severity and outcomes, compounded by doctors and patient anxiety adds to the quandary involving its management. This review summarises the literature around diagnosing and monitoring early onset fetal growth restriction (early onset FGR) with special emphasis on optimal timing of delivery as guided by recent research advances. PMID- 27693121 TI - Olfactory signaling components and olfactory receptors are expressed in tubule cells of the human kidney. AB - Cells of the renal tubule system are in direct contact with compounds dissolved in the urine, such as short chain fatty acids (SCFA). Murine OR78, a member of the olfactory receptor (OR) family, is involved in SCFA-related regulation of renal blood pressure in mice. It is still unclear whether OR signaling has an impact on human renal physiology. In our study, we showed that OR51E1 and OR11H7, both of which can be activated by the SCFA isovaleric acid, are expressed in the HK-2 human proximal tubule cell line. We observed a transient increase in intracellular Ca2+ when isovaleric acid and 4-methylvaleric acid were added to HK 2 cells. The isovaleric acid-induced response was dependent on extracellular Ca2+ and adenylyl cyclase (AC) activation. Furthermore, we demonstrated that the canonical olfactory signaling components Galphaolf and ACIII are co-localized with OR51E1. The number of cells responding to isovaleric acid correlated with the presence of primary cilia on HK-2 cells. OR51E1 protein expression was confirmed in the tubule system of human kidney tissue. Our study is the first to show the expression of ORs and olfactory signaling components in human kidney cells. Additionally, we discuss ORs as potential modulators of the renal physiology. PMID- 27693118 TI - Passive exposure to agricultural pesticides and risk of childhood leukemia in an Italian community. AB - BACKGROUND: Exposure to pesticides has been suggested as a risk factor for childhood leukemia, but definitive evidence on this relation and the specific pesticides involved is still not clear. OBJECTIVE: We carried out a population based case-control study in a Northern Italy community to assess the possible relation between passive exposure to agricultural pesticides and risk of acute childhood leukemia. METHODS: We assessed passive pesticide exposure of 111 childhood leukemia cases and 444 matched controls by determining density and type of agricultural land use within a 100-m radius buffer around children's homes. We focused on four common crop types, arable, orchard, vineyard and vegetable, characterized by the use of specific pesticides that are potentially involved in childhood induced leukemia. The use of these pesticides was validated within the present study. We computed the odds ratios (OR) of the disease and their 95% confidence intervals (CI) according to type and density of crops around the children's homes, also taking into account traffic pollution and high-voltage power line magnetic field exposure. RESULTS: Childhood leukemia risk did not increase in relation with any of the crop types with the exception of arable crops, characterized by the use of 2.4-D, MCPA, glyphosate, dicamba, triazine and cypermethrin. The very few children (n=11) residing close to arable crops had an OR for childhood leukemia of 2.04 (95% CI 0.50-8.35), and such excess risk was further enhanced among children aged <5 years. CONCLUSIONS: Despite the null association with most crop types and the statistical imprecision of the estimates, the increased leukemia risk among children residing close to arable crops indicates the need to further investigate the involvement in disease etiology of passive exposure to herbicides and pyrethroids, though such exposure is unlikely to play a role in the vast majority of cases. PMID- 27693122 TI - Competing Values Framework: A useful tool to define the predominant culture in a maternity setting in Australia. AB - OBJECTIVE: To identify the predominant culture of an organisation which could then assess readiness for change. DESIGN: An exploratory design using the Competing Values Framework (CVF) as a self-administered survey tool. SETTING: The Maternity Unit in one Australian metropolitan tertiary referral hospital. SUBJECTS: All 120 clinicians (100 midwives and 20 obstetricians) employed in the maternity service were invited to participate; 26% responded. MAIN OUTCOME MEASURE: The identification of the predominant culture of an organisation to assess readiness for change prior to the implementation of a new policy. RESULTS: The predominant culture of this maternity unit, as described by those who responded to the survey, was one of hierarchy with a focus on rules and regulations and less focus on innovation, flexibility and teamwork. These results suggest that this unit did not have readiness to change. CONCLUSION: There is value in undertaking preparatory work to gain a better understanding of the characteristics of an organisation prior to designing and implementing change. This understanding can influence additional preliminary work that may be required to increase the readiness for change and therefore increase the opportunity for successful change. The CVF is a useful tool to identify the predominant culture and characteristics of an organisation that could influence the success of change. PMID- 27693124 TI - Inhibitory effect of recombinant human endostatin on the proliferation of hypertrophic scar fibroblasts in a rabbit ear model. AB - Hypertrophic scar (HS) is a pathological scar that particularly occurs after traumatic injuries, surgical procedures and burning. Abnormal activation of hypertrophic scar fibroblasts (HSFs) intensifies fibrosis during wound healing. Our previous studies demonstrated that recombinant human endostatin (rhEndostatin) prevented synovial thickening in adjuvant arthritis (AA) rats via inhibition of proliferation and enhancement of apoptosis in synovial fibroblasts. However, the effect of this protein on HSF proliferation is not known. This study investigated the inhibitory effect of rhEndostatin on the proliferation of cultured HSFs in a rabbit ear model. MTT assay and flow cytometric detection were performed to investigate HSF proliferation and cell cycle progression, respectively. The expression levels of p53, p21, cyclinD1, cyclin-dependent kinase 4 (CDK4) and proliferating cell nuclear antigen (PCNA) in HSFs were detected using real-time PCR and Western blotting. Our data revealed that HSFs treated with rhEndostatin were significantly inhibited in a concentration dependent manner with an IC50 value of 100mg/L. Also, rhEndostatin (100mg/L) primarily induced G0/G1 and partially G2/M cell cycle arrest of HSFs. There were significant decreases in the expression levels of p53, p27, CDK4, cyclinD1 and PCNA in HSFs treated with rhEndostatin. In conclusion, rhEndostatin inhibited HSF proliferation via G0/G1 and/or G2/M phase arrest of the cell cycle, which was partially due to the down-regulation of cyclinD1, CDK4 and PCNA. These findings suggest that rhEndostatin may reduce scar hypertrophy in vivo via inhibition of HSF proliferation and may be a novel agent for HS treatment. PMID- 27693123 TI - The impact of perioperative beta blocker use on patient outcomes after primary cytoreductive surgery in high-grade epithelial ovarian carcinoma. AB - OBJECTIVE: To quantify the impact of perioperative beta blocker use on survival after primary cytoreductive surgery for epithelial ovarian cancer. METHODS: We conducted a multi-center retrospective study of all women who underwent primary cytoreductive surgery for ovarian cancer (2000-2010). One institution had routinely used perioperative beta blockers for patients "at risk" for coronary events. The other institution did not routinely use perioperative beta blockers. Demographic, operative, and follow up data were collected. Cox proportional hazards models were used to assess the effect of beta blockers on progression free interval (PFI) as well as overall survival (OS). RESULTS: Out of 185 eligible patients, 70 received beta blockers and 115 underwent cytoreductive surgery without perioperative beta blockers. Both groups were similar in demographics. A history of hypertension was present more often in the beta blocker group compared to the group that did not receive beta blockers (22% and 6%, p=0.002). PFI in beta blocker group was greater at 18.2 vs. 15.8months (p=0.66). The OS in the beta blocker group was significantly higher at 44.2 vs. 39.3months (p=0.01). In multivariate analysis, perioperative beta blocker use was associated with significant improvement in OS (HR 0.68 (0.46-0.99); p=0.046). CONCLUSION: Our study showed an association between perioperative beta blocker use and longer overall survival in patients undergoing primary ovarian cancer cytoreductive surgery. A prospective randomized clinical trial in this population would further validate these results. PMID- 27693125 TI - Pleiotrophin and its receptor protein tyrosine phosphatase beta/zeta as regulators of angiogenesis and cancer. AB - Pleiotrophin (PTN) is a secreted heparin-binding growth factor that through its receptor protein tyrosine phosphatase beta/zeta (RPTPbeta/zeta) has a significant regulatory effect on angiogenesis and cancer. PTN and RPTPbeta/zeta are over expressed in several types of human cancers and regulate important cancer cell functions in vitro and cancer growth in vivo. This review begins with a brief introduction of PTN and the regulation of its expression. PTN receptors are described with special emphasis on RPTPbeta/zeta, which also interacts with and/or affects the function of other important targets for cancer therapy, such as vascular endothelial growth factor A, alphanubeta3 and cell surface nucleolin. PTN biological activities related to angiogenesis and cancer are extensively discussed. Finally, up to date approaches of targeting PTN or RPTPbeta/zeta for cancer treatment are presented. Insights into the regulatory role of PTN/RPTPbeta/zeta on angiogenesis will be extremely beneficial for future development of alternative anti-angiogenic approaches in cancer therapy.

AB - BACKGROUND: In our previous study, Activin B induced actin stress fiber formation and cell migration in Bone marrow-derived mesenchymal stem cells (BMSCs) in vitro. However, the underlying molecular mechanisms are not well studied. RhoA is recognized to play a critical role in the regulation of actomyosin cytoskeletal organization and cell migration. METHODS: Pull-down assay was performed to investigate the activity of RhoA. The dominant-negative mutants of RhoA (RhoA(N19)) was used to determine whether RhoA has a role in Activin B-induced cytoskeleton organization and cell migration in BMSCs. Cytoskeleton organization was examined by fluorescence Rhodamine-phalloidin staining, and cell migration by transwell and cell scratching assay. Western blot was carried out to investigate downstream signaling cascade of RhoA. Inhibitor and siRNAs were used to detect the role of downstream signaling in stress fiber formation and/or cell migration. RESULTS: RhoA was activated by Activin B in BMSCs. RhoA(N19) blocked Activin B induced stress fiber formation and cell migration. ROCK inhibitor blocked Activin B-induced stress fiber formation but enhanced BMSCs migration. Activin B induced phosphorylation of LIMK2 and Cofilin, which was abolished by ROCK inhibition. Both of siRNA LIMK2 and siRNA Cofilin inhibited Activin B-induced stress fiber formation. CONCLUSIONS: RhoA regulates Activin B-induced stress fiber formation and migration of BMSCs. A RhoA-ROCK-LIMK2-Cofilin signaling node exists and regulates actin stress fiber formation. RhoA regulates Activin B-induced cell migration independent of ROCK. GENERAL SIGNIFICANCE: Better understanding of the molecular mechanisms of BMSCs migration will help optimize therapeutic strategy to target BMSCs at injured tissues. PMID- 27693128 TI - Adolescent Awareness and Use of Electronic Cigarettes: A Review of Emerging Trends and Findings. AB - Adult electronic cigarette (e-cigarette) use is increasing globally, and early studies have suggested that similar trends may be observed among the adolescent population, albeit at lower levels. The current literature review presents data collected since 2014 from 21 cross-sectional studies and one cohort study that were all published in English. In particular, it focuses on awareness, ever use, past 30-day use, and regular use of e-cigarettes. The article suggests that adolescents are nearing complete awareness of e-cigarettes. Furthermore, in relation to ever use and past 30-day use, higher prevalence rates continue to be reported across time, especially in the United States. Nonetheless, reported regular use of e-cigarettes remains much lower than past 30-day use, although conclusions are limited due to inconsistencies with measurement and consequent lack of cross-cultural applicability. The majority of studies do not report whether adolescents use non-nicotine e-cigarettes. There is a current absence of longitudinal studies that explore any association between e-cigarettes and tobacco use and little qualitative data that may illuminate how and why adolescents use e-cigarettes. Through addressing these methodological limitations, future research will be able to inform health care and policy more effectively. PMID- 27693129 TI - Data Mining of Web-Based Documents on Social Networking Sites That Included Suicide-Related Words Among Korean Adolescents. AB - PURPOSE: To investigate online search activity of suicide-related words in South Korean adolescents through data mining of social media Web sites as the suicide rate in South Korea is one of the highest in the world. METHODS: Out of more than 2.35 billion posts for 2 years from January 1, 2011 to December 31, 2012 on 163 social media Web sites in South Korea, 99,693 suicide-related documents were retrieved by Crawler and analyzed using text mining and opinion mining. These data were further combined with monthly employment rate, monthly rental prices index, monthly youth suicide rate, and monthly number of reported bully victims to fit multilevel models as well as structural equation models. RESULTS: The link from grade pressure to suicide risk showed the largest standardized path coefficient (beta = .357, p < .001) in structural models and a significant random effect (p < .01) in multilevel models. Depression was a partial mediator between suicide risk and grade pressure, low body image, victims of bullying, and concerns about disease. The largest total effect was observed in the grade pressure to depression to suicide risk. The multilevel models indicate about 27% of the variance in the daily suicide-related word search activity is explained by month-to-month variations. A lower employment rate, a higher rental prices index, and more bullying were associated with an increased suicide-related word search activity. CONCLUSIONS: Academic pressure appears to be the biggest contributor to Korean adolescents' suicide risk. Real-time suicide-related word search activity monitoring and response system needs to be developed.

Despite being at greater risk and having to deal with traumatic experiences and uncertainty, most adolescents with COCC do well across many domains. The Positive Youth Development (PYD) perspective provides a framework for examining thriving in youth and has been useful in understanding positive outcomes for general populations of youth as well as at-risk youth. This study aimed to compare levels of PYD assets between youth with COCC and youth without illness. METHODS: Participants with COCC were recruited from specialty pediatric clinics while healthy participants were recruited from a large pediatric primary care practice. Inclusion criteria for participants included being (1) English speaking, (2) no documented intellectual disability in electronic medical record, and (3) aged between 13 and 18 years during the recruitment period. Univariate and bivariate analyses on key variables were conducted for adolescents with and without COCC. Finally, we performed multivariable linear regressions for PYD and its subdomains. RESULTS: There were no significant differences between overall PYD or any of the subdomains between the two groups. Multivariable linear regression models showed no statistically significant relationship between chronic condition status and PYD or the subdomains. CONCLUSIONS: The findings from this study support the application of the PYD perspective to this population of youth. The results of this study suggest that approaches shown to benefit healthy youth, could be used to promote positive outcomes for youth with COCC.

AB - AIM: This study aimed to ascertain if performance on the Timed Up and Go (TUG) test is associated with indicators of brain volume and cognitive functions among community-dwelling older adults with normal cognition or mild cognitive impairment. METHODS: Participants were 80 community-dwelling older adults aged 65 89years (44 men, 36 women), including 20 with mild cognitive impairment. Participants completed the TUG and a battery of cognitive assessments, including the Mini-Mental State Examination (MMSE), the Logical Memory I and II (LM-I, LM II) subtests of the Wechsler Memory Scale-Revised; and the Trail Making Test A and B (TMT-A, TMT-B). Bilateral, right- and left-side medial temporal area atrophy as well as whole gray and white matter indices were determined with the Voxel-based Specific Regional Analysis System for Alzheimer's Disease. We divided participants into three groups based on TUG performance: "better" (<=6.9s); "normal" (7-10s); and "poor" (>=10.1s). RESULTS: Worse TMT-A and TMT-B performance showed significant independent associations with worse TUG performance (P<0.05, P<0.01 for trend, respectively). After adjusting for covariates, severe atrophy of bilateral, right-, and left-side medial temporal areas were significantly independently associated with worse TUG performance (P<0.05 for trend). However, no significant associations were found between MMSE, LM-I, LM-II, whole gray and white matter indices, and TUG performance. CONCLUSIONS: Worse TUG performance is related to poor performance on TMT-A and TMT-B, and is independently associated with severe medial temporal area atrophy in community-dwelling older adults.

AB - In comparison with the 2008 World Health Organization "Blue Book" on hematopoietic neoplasms, a small number of changes have been made in the classification. In the lower-risk patients, Refractory Cytopenias with Multilineage Dysplasia and Ring Sideroblasts (RCMD-RS) has been separated from RCMD to recognize the importance of the SF3B1 mutation. Often there has been confusion as to the degree of morphologic dysplasia and/or cytopenias to define some of the lower-risk subtypes. In addition, the type of dysplasia or cytopenias is not always concordant. Therefore, it seems prudent to apply the more general term "myelodysplastic syndrome (MDS)" with single- or multiple-lineage dysplasia. Refractory neutropenia or thrombocytopenia has been deemphasized because most patients have multilineage dysplasia. In the higher-risk patients, the terms Refractory Anemia with Excess Blasts (RAEB) 1 or 2 have been simplified to Myelodysplastic Syndrome-Excess Blasts (MDS-EB) 1 or 2 to emphasize the importance of the percentage of blasts that dictate therapy. Patients with Chronic Myelomonocytic Leukemia (CMML) can be classified into 3 groups: CMML 0, 1, or 2, based on the percentage of blasts (< 5%, 5%-9%, 10%-19%). Cases with 50% or more erythroid precursors will not have the percentage of blasts based on the nonerythroid precursors. Previous cases of acute erythroid leukemia (myeloid:erythroid type) can be included in the acute myeloid leukemia (AML) subtype: AML with MDS-related features.

AB - Prognostication of patients with diffuse large B-cell lymphoma (DLBCL) has improved in the past decade with a variety of clinical, morphologic, molecular, and radiographic methods. Comparable to data on the value of interim positron emission tomography (I-PET) in Hodgkin lymphoma, several retrospective and prospective studies are attempting to assess the value of I-PET scanning in DLBCL patients. In this review, we briefly describe and analyze the various prognostic methods in DLBCL with specific focus on the value of I-PET scanning in this disease. This is a timely analysis, as tailoring therapies based on prognosis at diagnosis are becoming of increased investigational interest. PMID- 27693135 TI - The Mesoderm-Forming Gene brachyury Regulates Ectoderm-Endoderm Demarcation in the Coral Acropora digitifera. AB - Blastoporal expression of the T-box transcription factor gene brachyury is conserved in most metazoans [1, 2]. Its role in mesoderm formation has been intensively studied in vertebrates [3-6]. However, its fundamental function near the blastopore is poorly understood in other phyla. Cnidarians are basal metazoans that are important for understanding evolution of metazoan body plans [7, 8]. Because they lack mesoderm, they have been used to investigate the evolutionary origins of mesoderm [1, 9-11]. Here, we focus on corals, a primitive clade of cnidarians that diverged from sea anemones ~500 mya [12]. We developed a microinjection method for coral eggs to examine Brachyury functions during embryogenesis of the scleractinian coral, Acropora digitifera. Because Acropora embryos undergo pharynx formation after the blastopore closes completely [13-15], they are useful to understand Brachyury functions in gastrulation movement and pharynx formation. We show that blastoporal expression of brachyury is directly activated by Wnt/beta-catenin signaling in the ectoderm of coral embryos, indicating that the regulatory axis from Wnt/beta-catenin signaling to brachyury is highly conserved among eumetazoans. Loss-of-function analysis demonstrated that Brachyury is required for pharynx formation but not for gastrulation movement. Genome-wide transcriptome analysis demonstrated that genes positively regulated by Brachyury are expressed in the ectoderm of Acropora gastrulae, while negatively regulated genes are in endoderm. Therefore, germ layer demarcation around the blastopore appears to be the evolutionarily conserved role of Brachyury during gastrulation. Compared with Brachyury functions in vertebrate mesoderm-ectoderm and mesoderm-endoderm demarcation [4-6], our results suggest that the vertebrate-type mesoderm may have originated from brachyury-expressing ectoderm adjacent to endoderm. PMID- 27693136 TI - Centrosome Amplification Increases Single-Cell Branching in Post-mitotic Cells. AB - Centrosome amplification is a hallmark of cancer, although we are still far from understanding how this process affects tumorigenesis [1, 2]. Besides the contribution of supernumerary centrosomes to mitotic defects, their biological effects in the post-mitotic cell are not well known. Here, we exploit the effects of centrosome amplification in post-mitotic cells during single-cell branching. We show that Drosophila tracheal cells with extra centrosomes branch more than wild-type cells. We found that mutations in Rca1 and CycA affect subcellular branching, causing tracheal tip cells to form more than one subcellular lumen. We show that Rca1 and CycA post-mitotic cells have supernumerary centrosomes and that other mutant conditions that increase centrosome number also show excess of subcellular lumen branching. Furthermore, we show that de novo lumen formation is impaired in mutant embryos with fewer centrioles. The data presented here define a requirement for the centrosome as a microtubule-organizing center (MTOC) for the initiation of subcellular lumen formation. We propose that centrosomes are necessary to drive subcellular lumen formation. In addition, centrosome amplification increases single-cell branching, a process parallel to capillary sprouting in blood vessels [3]. These results shed new light on how centrosomes can contribute to pathology independently of mitotic defects. PMID- 27693137 TI - Rats Remember Items in Context Using Episodic Memory. AB - Vivid episodic memories in people have been characterized as the replay of unique events in sequential order [1-3]. Animal models of episodic memory have successfully documented episodic memory of a single event (e.g., [4-8]). However, a fundamental feature of episodic memory in people is that it involves multiple events, and notably, episodic memory impairments in human diseases are not limited to a single event. Critically, it is not known whether animals remember many unique events using episodic memory. Here, we show that rats remember many unique events and the contexts in which the events occurred using episodic memory. We used an olfactory memory assessment in which new (but not old) odors were rewarded using 32 items. Rats were presented with 16 odors in one context and the same odors in a second context. To attain high accuracy, the rats needed to remember item in context because each odor was rewarded as a new item in each context. The demands on item-in-context memory were varied by assessing memory with 2, 3, 5, or 15 unpredictable transitions between contexts, and item-in context memory survived a 45 min retention interval challenge. When the memory of item in context was put in conflict with non-episodic familiarity cues, rats relied on item in context using episodic memory. Our findings suggest that rats remember multiple unique events and the contexts in which these events occurred using episodic memory and support the view that rats may be used to model fundamental aspects of human cognition. PMID- 27693138 TI - Honeybees Learn Landscape Features during Exploratory Orientation Flights. AB - Exploration is an elementary and fundamental form of learning about the structure of the world [1-3]. Little is known about what exactly is learned when an animal seeks to become familiar with the environment. Navigating animals explore the environment for safe return to an important place (e.g., a nest site) and to travel between places [4]. Flying central-place foragers like honeybees (Apis mellifera) extend their exploration into distances from which the features of the nest cannot be directly perceived [5-10]. Bees perform short-range and long-range orientations flights. Short-range flights are performed in the immediate surroundings of the hive and occur more frequently under unfavorable weather conditions, whereas long-range flights lead the bees into different sectors of the surrounding environment [11]. Applying harmonic radar technology for flight tracking, we address the question of whether bees learn landscape features during their first short-range or long-range orientation flight. The homing flights of single bees were compared after they were displaced to areas explored or not explored during the orientation flight. Bees learn the landscape features during the first orientation flight since they returned faster and along straighter flights from explored areas as compared to unexplored areas. We excluded a range of possible factors that might have guided bees back to the hive based on egocentric navigation strategies (path integration, beacon orientation, and pattern matching of the skyline). We conclude that bees localize themselves according to learned ground structures and their spatial relations to the hive. PMID- 27693139 TI - Imbalanced Activity in the Orbitofrontal Cortex and Nucleus Accumbens Impairs Behavioral Inhibition. AB - Contemporary models of behavioral regulation maintain that balanced activity between cognitive control areas (prefrontal cortex, PFC) and subcortical reward related regions (nucleus accumbens, NAC) mediates the selection of appropriate behavioral responses, whereas imbalanced activity (PFC < NAC) results in maladaptive behavior [1-6]. Imbalance can arise from reduced engagement of PFC (via fatigue or stress [7]) or from excessive activity in NAC [8]. Additionally, a concept far less researched is that an imbalance can result from simultaneously low PFC activity and high NAC activity. This occurs during adolescence, when the maturation of PFC lags behind that of NAC and NAC is more functionally active compared to adulthood or pre-adolescence [2, 5, 9, 10]. Accordingly, activity is disproportionately higher in NAC than in PFC, which may contribute to impulsivity and risk-taking exhibited by adolescents [5, 6, 10-12]. Despite having explanatory value, support for this notion has been solely correlational. Here, we causally tested this using chemogenetics to simultaneously decrease neural activity in the orbitofrontal cortex (OFC) and increase activity in NAC in adult rats, mimicking the imbalance during adolescence. We tested the effects on negative occasion setting, an important yet understudied form of inhibitory learning that may be particularly relevant during adolescence. Rats with combined manipulation of OFC and NAC were impaired in learning to use environmental cues to withhold a response, an effect that was greater than that of either manipulation alone. These findings provide direct evidence that simultaneous underactivity in OFC and overactivity in NAC can negatively impact behavioral control and provide insight into the neural systems that underlie inhibitory learning. PMID- 27693140 TI - Earliest Onychophoran in Amber Reveals Gondwanan Migration Patterns. AB - The anomalous occurrence of supposedly Gondwanan taxa in Laurasian-derived regions remains an intriguing chapter of paleobiogeographical history. Representatives of Peripatidae, a major subgroup of velvet worms (Onychophora), show a disjointed distribution in the neotropics, tropical Africa, and Southeast Asia, the latter being the only landmass previously associated with Laurasia [1, 2]. The arrival of these animals in Southeast Asia is explained by two alternative, albeit not mutually exclusive, hypotheses: an early migration via Europe before continental drift (Eurogondwana hypothesis) or transportation via insular India during the Cretaceous and Paleogene ("out-of-India" hypothesis) [3 6]. The latter hypothesis is based on a single extant species of Peripatidae, Typhloperipatus williamsoni, in India. ?Cretoperipatus burmiticus from Myanmar is the oldest fossil onychophoran found in amber [7], dating to sometime between the two proposed scenarios, and hence crucial for clarifying how Gondwanan lineages of these low-vagility animals reached Southeast Asia (see also Supplemental Information). Based on the anatomical reconstruction of ?C. burmiticus using synchrotron radiation-based X-ray microtomography (SRMUCT) and comparisons with extant taxa, we resolved this fossil species within Onychophora, particularly within Peripatidae, with T. williamsoni as its closest extant relative. This suggests that an early Eurogondwanan migration of peripatids was the most likely event, as Burmese amber is too old to be compatible with the out-of-India hypothesis. Moreover, peripatids probably colonized India only recently from Myanmar, refuting the putative Gondwanan relict status of Indian onychophorans. Finally, preservation artifacts identified in the novel amber material might have a major impact on studies of onychophoran stem and/or crown groups. PMID- 27693141 TI - Extreme Modification of the Tetrapod Forelimb in a Triassic Diapsid Reptile. AB - The tetrapod forelimb is one of the most versatile structures in vertebrate evolution, having been co-opted for an enormous array of functions. However, the structural relationships between the bones of the forelimb have remained largely unchanged throughout the 375 million year history of Tetrapoda, with a radius and ulna made up of elongate, paralleling shafts contacting a series of shorter carpal bones. These features are consistent across nearly all known tetrapods, suggesting that the morphospace encompassed by these taxa is limited by some sort of constraint(s). Here, we report on a series of three-dimensionally preserved fossils of the small-bodied (<1 m) Late Triassic diapsid reptile Drepanosaurus, from the Chinle Formation of New Mexico, USA, which dramatically diverge from this pattern. Along with the crushed type specimen from Italy, these specimens have a flattened, crescent-shaped ulna with a long axis perpendicular to that of the radius and hyperelongate, shaft-like carpal bones contacting the ulna that are proximodistally longer than the radius. The second digit supports a massive, hooked claw. This condition has similarities to living "hook-and-pull" digging mammals and demonstrates that specialized, modern ecological roles had developed during the Triassic Period, over 200 million years ago. The forelimb bones in Drepanosaurus represent previously unknown morphologies for a tetrapod and, thus, a dramatic expansion of known tetrapod forelimb morphospace. PMID- 27693142 TI - Sleep-Stage-Specific Regulation of Cortical Excitation and Inhibition. AB - Sleep is characterized by unique patterns of cortical activity alternating between the stages of slow-wave sleep (SWS) and rapid-eye movement (REM) sleep. How these patterns relate to the balanced activity of excitatory pyramidal cells and inhibitory interneurons in cortical circuits is unknown. We investigated cortical network activity during wakefulness, SWS, and REM sleep globally and locally using in vivo calcium imaging in mice. Wide-field imaging revealed a reduction in pyramidal cell activity during SWS compared with wakefulness and, unexpectedly, a further profound reduction in activity during REM sleep. Two photon imaging on local circuits showed that this suppression of activity during REM sleep was accompanied by activation of parvalbumin (PV)+ interneurons, but not of somatostatin (SOM)+ interneurons. PV+ interneurons most active during wakefulness were also most active during REM sleep. Our results reveal a sleep stage-specific regulation of the cortical excitation/inhibition balance, with PV+ interneurons conveying maximum inhibition during REM sleep, which might help shape memories in these networks. PMID- 27693143 TI - Fate of antibiotics from hospital and domestic sources in a sewage network. AB - Investigation of domestic and hospital effluents in a sewage system of an elementary watershed showed that antibiotics belonging to eight classes were present with concentrations ranging from H. cupressiforme>P. affine=A. humile. Phenanthrene enters the dead, empty hyalocysts of S. palustre. Specific surface area and composition, frequency and distribution of binding groups may also explain the different ability of phenanthrene uptake by the four moss species. PMID- 27693155 TI - The application of Diffusive Gradients in Thin Films (DGT) for improved understanding of metal behaviour at marine disposal sites. AB - Assessment of the effects of sediment metal contamination on biological assemblages and function remains a key question in marine management, especially in relation to disposal activities. However, the appropriate description of bioavailable metal concentrations within pore-waters has rarely been reported. Here, metal behaviour and availability at contaminated dredged material disposal sites within UK waters were investigated using Diffusive Gradient in Thin films (DGT). Three stations, representing contrasting history and presence of dredge disposal were studied. Depth profiles of five metals were derived using DGT probes as well as discrete analysis of total metal concentrations from sliced cores. The metals analysed were: iron and manganese, both relevant to sediment biogeochemistry; cadmium, nickel and lead, classified as priority pollutants. DGT time-integrated labile flux profiles of the metals display behaviour consistent with increasingly reduced conditions at depth and availability to DGT (iron and manganese), subsurface peaks and a potential sedimentary source to the water column related to the disposal activity (lead and nickel) and release to pore water linked to decomposition of enriched phytodetritus (cadmium). DGT data has the potential to improve our current understanding of metal behaviour at impacted sites and is suitable as a monitoring tool. DGT data can provide information on metal availability and fluxes within the sediment at high depth-resolution (5mm steps). Differences observed in the resulting profiles between DGT and conventional total metal analysis illustrates the significance of considering both total metals and a potentially labile fraction. The study outcomes can help to inform and improve future disposal site impact assessment, and could be complemented with techniques such as Sediment Profile Imagery for improved biologically relevance, spatial coverage and cost-effective monitoring and sampling of dredge material disposal sites. Additionally, the application of this technology could help improve correlative work on biological impacts under national and international auspices when linking biological effects to more biologically relevant metal concentrations. PMID- 27693156 TI - Refining correction factors for back-calculation of illicit drug use. AB - The estimation of illicit drugs use through wastewater analysis has become an important issue in the last few years due to their large worldwide consumption, which results in economic, social and health costs. The amounts of urinary biomarkers of illicit drugs (selected drugs or their metabolites) measured in wastewater are used to back-calculate the consumption of a particular drug by the population and to monitor temporal and spatial trends of illicit drug use in a community. The reliability of back-calculation depends on different factors, one being the accuracy of correction factors. A wide range of correction factors have been used in different studies and some biases must be expected when comparing results. Most of the correction factors were developed several years ago, so they need to be updated to include the latest information on pharmacokinetics. Moreover, new comprehensive methods to treat data should be adopted. The goal of this study is to refine current correction factors for back-calculation of the most widely used illicit drugs: amphetamine, methamphetamine, 3,4 methylenedioxymethamphetamine (MDMA) and tetrahydrocannabinol (THC). The mean percentages of excretion of the parent drugs and their metabolites were calculated for each route of administration, utilizing all accessible pharmacokinetic studies in the literature. This allowed to select the most suitable drug target residue and a refined correction factor was obtained for each substance considering the most frequent route of administration. The refined correction factors we propose can be used in wastewater based epidemiology to standardize the back-calculation of these drugs. These results can be included in the best practice protocol currently adopted in EU studies in order to reduce uncertainty and improve the comparability of results. PMID- 27693157 TI - Short- and medium-chain chlorinated paraffins in sediments from the middle reaches of the Yangtze River: Spatial distributions, source apportionment and risk assessment. AB - Chlorinated paraffins (CPs) are easily adsorbed into sediments where they pose potential risks to the ecosystem and human health. Few studies have investigated short- and medium-chain CPs (SCCPs and MCCPs) in sediments. The aim of the present study was to comprehensively investigate contamination levels, spatial distributions, sources and risks posed by CPs in sediments from the middle reaches of the Yangtze River. The sediment samples were analyzed by two dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC*GC-TOFMS). The concentrations of SCCPs and MCCPs ranged from 4.19 to 41.6ng/g dry weight (dw) and not detected to 14.6ng/g dw, respectively. No significant correlation was found between the total organic carbon contents and CP concentrations (P>0.05). The spatial distributions showed that CP contamination levels in the sediments were related to local human activities. The dominant congener groups were C10-11Cl6-7 for SCCPs, and C14Cl7-8 for MCCPs. Correspondence analysis revealed that likely sources of SCCPs were the production and use of CP-42 and CP-52. Principal component analysis indicated that SCCPs and MCCPs in the sediments may come from different sources. Moreover, CPs with nine carbon atoms were quantitated for the first time in sediment samples, and the results indicated they should not be neglected in future analyses. Risk assessments indicated that CPs in the sediments did not pose a great ecological risk currently. PMID- 27693158 TI - Telomere damage and redox status alterations in free-living passerines exposed to metals. AB - Telomere length may reflect the expected life span and possibly individual quality. Environmental stressors are known to increase oxidative stress and accelerate telomere attrition: however the interactions between redox status and telomere dynamics are not fully understood. We investigated whether exposure to heavy metal pollution is associated with oxidative stress and telomere damage in two insectivorous passerines, the Great tit (Parus major) and the Pied flycatcher (Ficedula hypoleuca). We were also interested to know whether within-brood competition could influence the nestling redox status or telomere length. Breeding females and nestlings were sampled near the point pollution source and compared to birds in non-polluted control zone. We measured heavy metal concentrations, calcium, metallothioneins, telomere lengths and redox status (oxidative damage, and enzymatic and non-enzymatic antioxidants) in liver samples. Great tit nestlings in the polluted zone had significantly shorter telomeres compared to those in the unpolluted control zone. In addition, those great tit nestlings that were lighter than their average siblings, had shorter telomeres compared to the heavier ones. In pied flycatchers neither pollution nor growth stress were associated with telomere length, but adult females had significantly shorter telomeres compared to the nestlings. All the results related to redox status varied remarkably among the species and the age groups. In both species antioxidants were related to pollution. There were no significant associations between redox status and telomere length. Our results suggest that wild birds at a young age are vulnerable to pollution and growth stress induced telomere damage. Redox status seems to interact with pollution and growth, but more studies are needed to clarify the underlying physiological mechanisms of telomere attrition. Our study highlights that all the observed associations and differences between the sampling zones varied depending on the species, age, and degree of exposure to pollution. PMID- 27693159 TI - Effects of etching time on alpha tracks in solid state nuclear track detectors. AB - Solid State Nuclear Track Detectors (SSNTDs) are used extensively for monitoring alpha particle radiation, neutron flux and cosmic ray radiation. Radon gas inhalation is regarded as being a significant contributory factor to lung cancer deaths in the UK each year. Gas concentrations are often monitored using CR39 based SSNTDs as the natural decay of radon results in alpha particles which form tracks in these detectors. Such tracks are normally etched for about 4h to enable microscopic analysis. This study examined the effect of etching time on the appearance of alpha tracks in SSNTDs by collecting 2D and 3D image datasets using laser confocal microscope imaging techniques. Etching times of 2 to 4h were compared and marked differences were noted in resultant track area. The median equivalent diameters of tracks were 20.2, 30.2 and 38.9MUm for etching at 2, 3 and 4h respectively. Our results indicate that modern microscope imaging can detect and image the smaller size tracks seen for example at 3h etching time. Shorter etching times may give rise to fewer coalescing tracks although there is a balance to consider as smaller track sizes may be more difficult to image. Thus etching for periods of less than 4h clearly merits further investigation as this approach has the potential to improve accuracy in assessing the number of tracks. PMID- 27693160 TI - Effect of magnetite nanoparticles on the germination and early growth of Quercus macdougallii. AB - The present study measures the effect of citrate-coated magnetite nanoparticles (Fe3O4-NPs) on the germination and early growth of Quercus macdougallii (oak). Two types of Fe3O4-NPs were synthetized and characterized, being denominated NP1 and NP2. The synthesis was performed by the co-precipitation method and partial reduction of iron(II), respectively. It was found that the NP1 has a quasi spherical morphology, with sizes of 6-10nm, while the NP2 has sizes between 65 and 160nm. It was demonstrated that the Fe3O4-NPs exhibit peroxidase-like catalytic activity. Experiments of germination and growth of Quercus macdougallii were performed using the synthesized Fe3O4-NPs treatments and a deionized water control. The experiments were performed in intact and peeled acorns. The application of the NPs increased the germination up to 33% in relation to the control. Additionally, the Fe3O4-NPs treatments increased the growth, dry biomass, and chlorophyll concentration. The data obtained in this study suggest that Fe3O4-NPs treatments could be potentially used to improve conservation and reforestation of threatened forestry species. PMID- 27693161 TI - Hepatitis B virus genetic diversity has minimal impact on sensitivity of the viral ribonuclease H to inhibitors. AB - Hepatitis B virus (HBV) causes hepatitis, cirrhosis, liver failure, and liver cancer, but the current therapies that employ either nucelos(t)ide analogs or (pegylated)interferon alpha do not clear the infection in the large majority of patients. Inhibitors of the HBV ribonuclease H (RNaseH) that are being developed with the goal of producing anti-HBV drugs are promising candidates for use in combination with the nucleos(t)ide analogs to improve therapeutic efficacy. HBV is genetically very diverse, with at least 8 genotypes that differ by >=8% at the sequence level. This diversity is reflected in the viral RNaseH enzyme, raising the possibility that divergent HBV genotypes or isolates may have varying sensitivity to RNaseH inhibitors. To evaluate this possibility, we expressed and purified 18 patient-derived RNaseHs from genotypes B, C, and D. Basal RNaseH activity and sensitivity to three novel RNaseH inhibitors from three different chemotypes were assessed. We also evaluated four consensus HBV RNaseHs to determine if such sequences would be suitable for use in antiviral drug screening. The patient-derived enzymes varied by over 10-fold in their basal RNaseH activities, but they were equivalently sensitive to each of the three inhibitors. Similarly, all four consensus HBV RNaseH enzymes were active and were equally sensitive to an RNaseH inhibitor. These data indicate that a wide range of RNaseH sequences would be suitable for use in antiviral drug screening, and that genotype- or isolate-specific genetic variations are unlikely to present a barrier during antiviral drug development against the HBV RNaseH. PMID- 27693162 TI - [Reduction of rehospitalisation on elderly heart failure patients: A retrospective cohort VISage network]. AB - BACKGROUND: Heart failure was a public health problem for one million of French patients. Patients are particularly concerned in rehospitalisation for this chronic pathology. A specific healthcare network was created to take care of patients with heart failure directly at home. This healthcare network (named VISage) brings a specific and adapted monitoring in heart failure. The main of this study was to evaluate the impact of healthcare network in rehospitalisation rate for heart failure of patients. MATERIAL AND METHODS: We conducted a retrospective cohort study with patients' hospital files of the CH Vienne. Patients who were included in our healthcare network (VISage) were screened. Primary endpoint was 30days, 6 months, and 1year rehospitalisation rate for heart failure before and after using healthcare network. RESULTS: One hundred and four patients with comorbidities were included between February 2009 and November 2015. A significant reduction of rehospitalisation rate for heart failure was observed before and after network: 0.65 (+/-0.52) vs. 0.17 (+/-0.43) 30days, 1.17 (+/-0.74) vs. 0.42 (+/-0.71) at 6 months and 1.35 (+/-0.95) vs. 0.47 (+/-0.74) at 1 year (P<0.0001). Results were significant for global rehospitalisation rate too. No significant differences were shown on hospital length of stay. CONCLUSION: Coordinated healthcare by a specific network at home for elderly is benefic for the rehospitalisation rate. PMID- 27693163 TI - [Usefulness of natriuretic peptide testing and Doppler echocardiography at bedside in the diagnosis of acute heart failure]. AB - Acute heart failure is a common condition that leads to hospital admission, with important mortality and readmission rates. A prompt and accurate diagnosis of this condition by hospitalists is essential for an early and tailored medical management. The use of natriuretic peptide testing (BNP and NT-proBNP) through a two cut-point strategy is currently recommended as the first-line diagnostic complement to the initial clinical evaluation in the acute care setting. Transthoracic Doppler echocardiography is an other noninvasive method that can be used at bedside, especially in patients with intermediate, inconclusive natriuretic peptides levels. In this regard, left ventricular ejection fraction and several simple Doppler indexes (restrictive mitral filling pattern, spectral tissue Doppler E/e' ratio), have been validated in the emergency diagnosis of acute heart failure. The aim of the present review is to overview the respective contribution of natriuretic peptides and Doppler echocardiography at bedside to the diagnosis of acute heart failure in the acute care setting. PMID- 27693164 TI - [Outpatient management of pulmonary embolism diagnosed in emergency services]. AB - In the emergency department, the management of patients with pulmonary embolism depends on the early mortality risk. Outpatient care is possible in low-risk patients. We present the existing scores and the strategy proposed by the North Alps Emergency Network, which uses the simplified PESI score (Pulmonary Embolism Severity Index) to select those low-risk patients, candidates for early discharge. PMID- 27693165 TI - [Fast track chest pain pathway in emergency department]. AB - Acute chest pain is a common reason of consultation in the emergency department. The difficulty lies in discriminating patients with acute coronary syndrome or other life-threatening conditions from those non-cardiovascular, non-life threatening chest pain. Only 15 to 25 % of patients with acute chest pain actually have acute coronary syndrome. Algorithms using high sensitivity troponin at admission and a second assessment 1 or 3hours later are validated to "rule in" or "rule out" the diagnosis of non ST-elevation myocardial infarction. This may reduce the delay for the diagnosis translating into shorter stay in the emergency department. Those algorithms must be interpreted in the context of clinical and ECG criteria.

We aim to evaluate the effect of the intracoronary administration of antithrombotic agents via a perfusion catheter in patients with ST-segment elevation myocardial infarction (STEMI) presenting with a large thrombus burden and failed aspiration. METHODS: We retrospectively analyzed the thrombus burden, the TIMI grade flow, and the myocardial Blush in 25 consecutive STEMI patients with a large thrombus burden and failed manual aspiration, who received intracoronary infusion of glycoprotein IIb/IIIa inhibitors (N=17) or bivalirudine (N=8) via a 6F-infusion catheter (ClearWayTM RX) RESULTS: Mean age was 67+/-14 years, 16 patients (64 %) presented with anterior STEMI, and 7 (28 %) with cardiogenic shock. Immediately after intracoronary infusion, the TIMI flow grade improved of 2 grades in 7 patients (28 %), and 1 grade in 14 (56 %), a complete resolution of the thrombus was observed in 9 patients, and a >50 % resolution in 12. Blush was improved of 3 grades in 15 patients (60 %), of 2 grades in 7 (28 %), and Blush grade 0 remained in 3. At the end of procedure, we observed normal TIMI 3flow in most patients (92 %), a complete resolution of thrombus in 80 %, and a Blush grade 3 in 68 %. CONCLUSIONS: In STEMI patients presenting with a large thrombus burden and failed aspiration, intracoronary administration of glycoprotein IIb/IIIa inhibitors or bivalirudin via the perfusion catheter ClearWayTM RX significantly reduced the thrombus burden and improved the TIMI flow and the Blush grade, without bleeding.

AB - INTRODUCTION: Management of antiplatelet therapy at the time of device implantation remains controversial. This study aimed to assess the risk of bleeding complications in patients receiving ticagrelor at the time of cardiac device surgery. METHODS: We performed a multicentre (n=4), retrospective study from January 2015 to January 2016. The survey included all patients (pts) treated with ticagrelor before undergoing pacemaker, implantable cardioverter defibrillator (ICD) implantation or generator replacement. We report hemorrhagic post-procedural complications at 1 month. A significant bleeding complication was defined as pocket hematoma requiring a surgical evacuation or prolonged hospitalization, hemothorax, pericardial effusion, or tamponade. RESULTS: A total of 20 patients underwent a permanent pacemaker or ICD implantation while taking a combination of antipatelet therapy with ticagrelor and aspirin. The mean age of the patients was 65+/-9 years, 95% were male, 25% of patients were diabetics, 55% had hypertension and 50% presented a history of heart failure. All the patients had a history of acute coronary syndrome [6 (4-26) months before the procedure]. The majority of implanted devices were ICDs (17, 85%) with 5 single chamber, 4 dual chambers and 9 triple chambers ICDs. Subclavian venous approach was utilized in 9 patients. The mean duration of procedure was 60minutes. One per-procedure bleeding was described due to high venous pressure, without post-procedure hematoma. A post-procedure pocket hematoma has been experienced by one patient. The subclavian approach was used for the 2 patients. No blood transfusion was needed for these 2 cases. CONCLUSION: Ticagrelor treatment at the time of heart rhythm device procedures does not seem to be associated with an increased risk of significant bleeding complications. In our study, 2 patients experienced nonsignificant bleeding complications.

AB - Transcatheter aortic valve implantation (TAVI) is nowadays a worldwide technique in the field of treating aortic stenosis. One of the main side effects linked to the technique are mostly attached to rhythm disturbances, such as atrioventricular (AV) and intraventricular blocks. Consequently, a pacemaker implantation is often required. That implantation rate is estimated between 8 and 30%, depending on the valve chosen. Thanks to main meta analysis on the subject, it has been managed to isolate the following risks factors for AV block development: preoperative right bundle branch block (RBBB: the most powerful element), complete AV block during the procedure, male gender, a so-called porcelain aorta, the absence of previous valvular surgery, the aortic annulus size (i.e when that size is inferior to the valve's one) and the QRS duration after the procedure (the superior threshold has been set at 128ms for the Corevalve). The currently recommendations advice to implant a pacemaker are as followed: high grade AV block (in the main studies, the implantation occurs within the 5 days after the TAVI), complete and transient AV block during the TAVI, second degree AV block and RBBB associated with first degree AV block. Our article aims to review the arrhythmic issues of TAVI. PMID- 27693169 TI - [Troponin elevation in the absence of acute coronary syndrome]. AB - Cardiac troponins are the most sensitive and specific markers of myocardial injury. Cardiac troponin elevation are common in many diseases and do not necessarily indicate the presence of a thrombotic acute coronary syndrome. In clinical practice, interpretation of dynamic changes of troponin may be challenging. Troponin evaluation should be performed only if clinically indicated and must be interpreted in the context of clinical presentation, ECG changes, troponin level and kinetic. In the absence of thrombotic acute coronary syndrom, troponin retains a prognostic value. Its practical interest as a risk criteria is limited to a few situations like pulmonary embolism, pericarditis an myocarditis. PMID- 27693170 TI - Preclinical study investigating the potential of low-dose-rate brachytherapy with 32P stents for the prevention of restenosis of paranasal neo-ostia. AB - PURPOSE: Ostial restenosis is a common cause of failures in paranasal sinus surgery. The aim of the current study was to investigate the use of low-dose-rate brachytherapy to prevent neo-ostial restenosis in an animal model. METHODS AND MATERIALS: In 14 rabbits, maxillary neo-ostia were created and measured. One side each was stented with a regular silicone stent, the other side was either not stented (n = 7) or stented with a phosphorous-32 implanted stent depositing a low dose radiation of 15 Gy (n = 7) within 1 week, after which all stents were removed. After a period of additional 12 weeks of recovery, the animals were sacrificed, the neo-ostia were again measured, and the areas and histopathologic changes compared in between the groups. RESULTS: After 15-Gy stenting, the mean ostial areas were even slightly enlarged by 5.1% compared to the area at stent removal, whereas a significant reduction in area, indicating a process of restenosis, by 56.1% or 54.0% was seen in the control groups with no stent and normal stent, respectively. Furthermore, no indication for adverse histopathologic radiation effects was seen in the 15-Gy group. CONCLUSIONS: Low dose-rate brachytherapy with phosphorous-32 doped silicone stents showed promising results in the prevention of neo-ostium restenosis in this proof-of concept study, indicating that further preclinical and clinical testing may be warranted. PMID- 27693171 TI - The dosimetric impact of air in vaginal vault brachytherapy. AB - PURPOSE: Vaginal vault brachytherapy is an adjuvant treatment to reduce risk of local recurrence in endometrial cancer. Axial imaging has demonstrated the presence of air gaps between the surface of a cylindrical applicator and mucosal wall. The impact of these on dosimetry and applicability of the TG-43 formalism in the presence of air has been assessed. METHODS AND MATERIALS: The planning CT scans for a retrospective sample of 82 patients were examined for the presence of air gaps. These were quantified in terms of the radial and longitudinal aspect with reference to the applicator, frequency per patient, and location along the applicator. Monte Carlo calculations and ionization chamber measurements were made in a phantom to estimate the uncertainty of the TG-43 algorithm. RESULTS: The overall incidence of air gaps was 91.4%. The most common radial size was between 2 and 3 mm (43.0%) that resulted in an average dose reduction of 14.8%. There is a strong correlation between radial dimension and TG-43 calculated dose reduction. Monte Carlo simulations and phantom measurements indicated that the inhomogeneity resulted in a maximum of 2.4% deviation from doses calculated using TG-43. CONCLUSIONS: Air gaps are common. TG-43 formalism is not significantly compromised by the presence of air. However, the presence of the air does produce a displacement of the mucosal surface away from the applicator and this causes a significant dose reduction. PMID- 27693172 TI - Combining transrectal ultrasound and CT for image-guided adaptive brachytherapy of cervical cancer: Proof of concept. AB - PURPOSE: To investigate the feasibility of a treatment planning workflow for three-dimensional image-guided cervix cancer brachytherapy, combining volumetric transrectal ultrasound (TRUS) for target definition with CT for dose optimization to organs at risk (OARs), for settings with no access to MRI. METHODS AND MATERIALS: A workflow for TRUS/CT-based volumetric treatment planning was developed, based on a customized system including ultrasound probe, stepper unit, and software for image volume acquisition. A full TRUS/CT-based workflow was simulated in a clinical case and compared with MR- or CT-only delineation. High risk clinical target volume was delineated on TRUS, and OARs were delineated on CT. Manually defined tandem/ring applicator positions on TRUS and CT were used as a reference for rigid registration of the image volumes. Treatment plan optimization for TRUS target and CT organ volumes was performed and compared to MRI and CT target contours. RESULTS: TRUS/CT-based contouring, applicator reconstruction, image fusion, and treatment planning were feasible, and the full workflow could be successfully demonstrated. The TRUS/CT plan fulfilled all clinical planning aims. Dose-volume histogram evaluation of the TRUS/CT-optimized plan (high-risk clinical target volume D90, OARs D2cm3 for) on different image modalities showed good agreement between dose values reported for TRUS/CT and MRI only reference contours and large deviations for CT-only target parameters. CONCLUSIONS: A TRUS/CT-based workflow for full three-dimensional image-guided cervix brachytherapy treatment planning seems feasible and may be clinically comparable to MRI-based treatment planning. Further development to solve challenges with applicator definition in the TRUS volume is required before systematic applicability of this workflow. PMID- 27693173 TI - Point A vs. HR-CTV D90 in MRI-based cervical brachytherapy of small and large lesions. AB - PURPOSE: To evaluate the dosimetric benefits of MRI-based brachytherapy in small and large high-risk clinical target volume (HR-CTV) in cervical cancer. METHODS AND MATERIALS: Twenty-eight fractions obtained from sixteen cervical cancer patients treated with MRI-based high-dose-rate brachytherapy with standard tandem and ovoid applicators were used; original fractions were optimized to HR-CTV D90. Fractions were separated based on the median volume into small and large (HR-CTV <25 cm3 or >25 cm3) lesion groups. Retrospective plans prescribed to Point A were created for each fraction. D0.1 cc, D2 cc, and International Commission of Radiation Unit and Measurements (ICRU) points were used to compare Point A vs. HR CTV D90 plans for bladder, rectum, and sigmoid. RESULTS: In the small lesion group, Point A plans vs. HR-CTV D90 plans had significantly higher D0.1 cc, D2 cc, and ICRU points for bladder, rectum, and sigmoid (p < 0.05). In the large lesion group, there was no significant difference between Point A and HR-CTV D90 plans for D0.1 cc, D2 cc, and ICRU points to the organs at risk (OARs). CONCLUSIONS: The dosimetric advantages to OARs offered by MRI-based brachytherapy with prescription to HR-CTV D90 compared to Point A is most distinct for patients with smaller HR-CTV (<25 cm3). This study demonstrates sufficient tumor coverage with lower doses to OARs in HR-CTV D90 vs. Point A plans in the small lesion group. These improvements were not seen in the large lesion group, indicating a lesser dosimetric advantage of HR-CTV D90 compared to Point A planning when the cervical lesion is >25 cm3. Incorporation of interstitial needles for patients with larger HR-CTV is likely the best method to decrease dose to OARs and improve tumor coverage.

AB - Data on community-associated extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (CA-ESBLEC) infections in Japan are scarce. We compared the clinical and microbiological epidemiology of CA-ESBLEC infections with that of healthcare-associated-ESBLEC infections among 76 patients with ESBLEC infections. We identified a high prevalence (26%) of CA-ESBLEC infections in Japan; only a small proportion (15%) of patients with CA-ESBLEC infections had recent exposure to antibiotics. PMID- 27693181 TI - Amyloid tracers binding sites in autosomal dominant and sporadic Alzheimer's disease. AB - INTRODUCTION: Amyloid imaging has been integrated into diagnostic criteria for Alzheimer's disease (AD). How amyloid tracers binding differ for different tracer structures and amyloid-beta aggregates in autosomal dominant AD (ADAD) and sporadic AD is unclear. METHODS: Binding properties of different amyloid tracers were examined in brain homogenates from six ADAD with APPswe, PS1 M146V, and PS1 EDelta9 mutations, 13 sporadic AD, and 14 control cases. RESULTS: 3H-PIB, 3H florbetaben, 3H-AZD2184, and BTA-1 shared a high- and a varying low-affinity binding site in the frontal cortex of sporadic AD. AZD2184 detected another binding site (affinity 33 nM) in the frontal cortex of ADAD. The 3H-AZD2184 and 3H-PIB binding were significantly higher in the striatum of ADAD compared to sporadic AD and control. Polyphenol resveratrol showed strongest inhibition on 3H AZD84 binding followed by 3H-florbetaben and minimal on 3H-PIB. DISCUSSION: This study implies amyloid tracers of different structures detect different sites on amyloid-beta fibrils or conformations.

PMID- 27693183 TI - Association of blood lipids with Alzheimer's disease: A comprehensive lipidomics analysis. AB - INTRODUCTION: The aim of this study was to (1) replicate previous associations between six blood lipids and Alzheimer's disease (AD) (Proitsi et al 2015) and (2) identify novel associations between lipids, clinical AD diagnosis, disease progression and brain atrophy (left/right hippocampus/entorhinal cortex). METHODS: We performed untargeted lipidomic analysis on 148 AD and 152 elderly control plasma samples and used univariate and multivariate analysis methods. RESULTS: We replicated our previous lipids associations and reported novel associations between lipids molecules and all phenotypes. A combination of 24 molecules classified AD patients with >70% accuracy in a test and a validation data set, and we identified lipid signatures that predicted disease progression (R2 = 0.10, test data set) and brain atrophy (R2 >= 0.14, all test data sets except left entorhinal cortex). We putatively identified a number of metabolic features including cholesteryl esters/triglycerides and phosphatidylcholines. DISCUSSION: Blood lipids are promising AD biomarkers that may lead to new treatment strategies. PMID- 27693184 TI - Which types of mental work demands may be associated with reduced risk of dementia? AB - INTRODUCTION: Previous studies have demonstrated that an overall high level of mental work demands decreased dementia risk. In our study, we investigated whether this effect is driven by specific mental work demands and whether it is exposure dependent. METHODS: Patients aged 75+ years were recruited from general practitioners and participated in up to seven assessment waves (every 1.5 years) of the longitudinal AgeCoDe study. Analyses of the impact of specific mental work demands on dementia risk were carried out via multivariate regression modeling (n = 2315). RESULTS: We observed a significantly lower dementia risk in individuals with a higher level of "information processing" (HR, 0.888), "pattern detection" (HR, 0.878), "mathematics" (HR, 0.878), and "creativity" (HR, 0.878). Yet, exposure-dependent effects were only significant for "information processing" and "pattern detection." DISCUSSION: Our longitudinal observations suggest that dementia risk may be reduced by some but not all types of mental work demands. PMID- 27693186 TI - The financial burden and health care utilization patterns associated with amnestic mild cognitive impairment. AB - INTRODUCTION: Individuals with amnestic mild cognitive impairment (aMCI) are at elevated risk of developing Alzheimer's disease (AD) dementia. METHODS: With data from the Aging, Demographics, and Memory Study, we used the Clinical Dementia Rating Sum of Boxes classifications to conduct a cross-sectional analysis assessing the relationship between cognitive state and various direct and indirect costs and health care utilization patterns. RESULTS: Patients with aMCI had less medical expenditures than patients with moderate and severe AD dementia (P < .001) and were also significantly less likely to have been hospitalized (P = .04) and admitted to nursing home (P < .001). Compared to individuals with normal cognition, patients with aMCI had significantly less household income (P = .018). DISCUSSION: Patients with aMCI had lower medical expenditures than patients with AD dementia. Poor cognitive status was linearly associated with lower household income, higher medical expenditures, higher likelihood of nursing and home care services, and lower likelihood of outpatient visits. PMID- 27693187 TI - Subjective cognitive decline in cognitively normal elders from the community or from a memory clinic: Differential affective and imaging correlates. AB - INTRODUCTION: Subjective cognitive decline (SCD) could indicate preclinical Alzheimer's disease, but the existing literature is confounded by heterogeneous approaches to studying SCD. We assessed the differential cognitive, affective, and neuroimaging correlates of two aspects of SCD: reporting high cognitive difficulties on a self-rated questionnaire versus consulting at a memory clinic. METHODS: We compared 28 patients from a memory clinic with isolated SCD, 35 community-recruited elders with similarly high levels of self-reported cognitive difficulties, and 35 community-recruited controls with low self-reported cognitive difficulties. RESULTS: Increased anxiety and amyloid beta deposition were observed in both groups with high self-reported difficulties, whereas subclinical depression and (hippocampal) atrophy were specifically associated with medical help seeking. Cognitive tests showed no group differences. DISCUSSION: These results further validate the concept of SCD in both community- and clinic-based groups. Yet, recruitment methods influence associated biomarkers and affective symptomatology, highlighting the heterogeneous nature of SCD depending on study characteristics. PMID- 27693185 TI - mTOR and neuronal cell cycle reentry: How impaired brain insulin signaling promotes Alzheimer's disease. AB - A major obstacle to presymptomatic diagnosis and disease-modifying therapy for Alzheimer's disease (AD) is inadequate understanding of molecular mechanisms of AD pathogenesis. For example, impaired brain insulin signaling is an AD hallmark, but whether and how it might contribute to the synaptic dysfunction and neuron death that underlie memory and cognitive impairment has been mysterious. Neuron death in AD is often caused by cell cycle reentry (CCR) mediated by amyloid-beta oligomers (AbetaOs) and tau, the precursors of plaques and tangles. We now report that CCR results from AbetaO-induced activation of the protein kinase complex, mTORC1, at the plasma membrane and mTORC1-dependent tau phosphorylation, and that CCR can be prevented by insulin-stimulated activation of lysosomal mTORC1. AbetaOs were also shown previously to reduce neuronal insulin signaling. Our data therefore indicate that the decreased insulin signaling provoked by AbetaOs unleashes their toxic potential to cause neuronal CCR, and by extension, neuron death. PMID- 27693188 TI - A common challenge in older adults: Classification, overlap, and therapy of depression and dementia. AB - Late-life depression is frequently associated with cognitive impairment. Depressive symptoms are often associated with or even precede a dementia syndrome. Moreover, depressive disorders increase the risk of persistence for mild cognitive impairment and dementia. Here, we present both the current state of evidence and future perspectives regarding the integration and value of clinical assessments, neuropsychological, neurochemical, and neuroimaging biomarkers for the etiological classification of the dementia versus the depression syndrome and for the prognosis of depression relating to dementia risk. Finally, we summarize the existing evidence for both pharmacotherapy and psychotherapy of depression in demented patients. There is an urgent need for large-scale collaborative research to elucidate the role and interplay of clinical and biological features in elderly individuals with depressive disorders who are at elevated risk for developing dementia. To overcome barriers for successful drug development, we propose the introduction of the precision medicine paradigm to this research field. PMID- 27693189 TI - Longitudinal brain structural changes in preclinical Alzheimer's disease. AB - INTRODUCTION: Brain structural changes in preclinical Alzheimer's disease (AD) are poorly understood. METHODS: We compared the changes in cortical thickness in the ADNI cohort during a 2-year follow-up between the NIA-AA preclinical AD stages defined by cerebrospinal fluid (CSF) biomarker levels. We also analyzed the correlation between baseline CSF biomarkers and cortical atrophy rates. RESULTS: At follow-up, stage 1 subjects showed reduced atrophy rates in medial frontal areas and precuneus compared to stage 0 subjects, whereas stage 2/3 subjects presented accelerated atrophy in medial temporal structures. Low CSF Abeta1-42 levels were associated with reduced atrophy rates in subjects with normal tau levels and high CSF tau levels with accelerated atrophy only in subjects with low Abeta1-42 levels. DISCUSSION: Our longitudinal data confirm a biphasic trajectory of changes in brain structure in preclinical AD. These have implications in AD trials, both in patient selection and the use of MRI as a surrogate marker of efficacy. PMID- 27693190 TI - Mastoparan is a membranolytic anti-cancer peptide that works synergistically with gemcitabine in a mouse model of mammary carcinoma. AB - Anti-cancer peptides (ACPs) are small cationic and hydrophobic peptides that are more toxic to cancer cells than normal cells. ACPs kill cancer cells by causing irreparable membrane damage and cell lysis, or by inducing apoptosis. Direct acting ACPs do not bind to a unique receptor, but are rather attracted to several different molecules on the surface of cancer cells. Here we report that an amidated wasp venom peptide, Mastoparan, exhibited potent anti-cancer activities toward leukemia (IC50~8-9.2MUM), myeloma (IC50~11MUM), and breast cancer cells (IC50~20-24MUM), including multidrug resistant and slow growing cancer cells. Importantly, the potency and mechanism of cancer cell killing was related to the amidation of the C-terminal carboxyl group. Mastoparan was less toxic to normal cells than it was to cancer cells (e.g., IC50 to PBMC=48MUM). Mastoparan killed cancer cells by a lytic mechanism. Moreover, Mastoparan enhanced etoposide induced cell death in vitro. Our data also suggest that Mastoparan and gemcitabine work synergistically in a mouse model of mammary carcinoma. Collectively, these data demonstrate that Mastoparan is a broad-spectrum, direct acting ACP that warrants additional study as a new therapeutic agent for the treatment of various cancers. PMID- 27693191 TI - Differentially expressed genes selection via Laplacian regularized low-rank representation method. AB - With the rapid development of DNA microarray technology and next-generation technology, a large number of genomic data were generated. So how to extract more differentially expressed genes from genomic data has become a matter of urgency. Because Low-Rank Representation (LRR) has the high performance in studying low dimensional subspace structures, it has attracted a chunk of attention in recent years. However, it does not take into consideration the intrinsic geometric structures in data. In this paper, a new method named Laplacian regularized Low Rank Representation (LLRR) has been proposed and applied on genomic data, which introduces graph regularization into LRR. By taking full advantages of the graph regularization, LLRR method can capture the intrinsic non-linear geometric information among the data. The LLRR method can decomposes the observation matrix of genomic data into a low rank matrix and a sparse matrix through solving an optimization problem. Because the significant genes can be considered as sparse signals, the differentially expressed genes are viewed as the sparse perturbation signals. Therefore, the differentially expressed genes can be selected according to the sparse matrix. Finally, we use the GO tool to analyze the selected genes and compare the P-values with other methods. The results on the simulation data and two real genomic data illustrate that this method outperforms some other methods: in differentially expressed gene selection. PMID- 27693192 TI - A snake-like serine proteinase (PmSnake) activates prophenoloxidase-activating system in black tiger shrimp Penaeus monodon. AB - Clip domain serine proteinases (ClipSPs) play critical roles in the activation of proteolytic cascade in invertebrate immune systems including the prophenoloxidase (proPO) activating system. In this study, we characterized a snake-like serine protease, namely PmSnake, from the shrimp Penaeus monodon which has previously been identified based on the subtractive cDNA library of proPO double-stranded RNA (dsRNA)-treated hemocytes. An open reading frame of PmSnake contains 1068 bp encoding a predicted protein of 355 amino acid residues with a putative signal peptide of 22 amino acids and two conserved domains (N-terminal clip domain and C terminal trypsin-like serine proteinase domain). Sequence analysis revealed that PmSnake was closest to the AeSnake from ant Acromyrmex echinatior (53% similarity), but was quite relatively distant from other shrimp PmclipSPs. PmSnake transcript was mainly expressed in shrimp hemocytes and up-regulated after systemic Vibrio harveyi infection indicating that it is an immune responsive gene. Suppression of PmSnake expression by dsRNA interference reduced both transcript and protein levels leading to a reduction of the hemolymph phenoloxidase (PO) activity (36%), compared to the control, suggesting that the PmSnake functions as a clip-SP in shrimp proPO system. Western blot analysis using anti-PmSnake showed that the PmSnake was detected in hemocytes but not in cell-free plasma. In vitro PO activity and serine proteinase activity assays showed that adding rPmSnake into the shrimp hemolymph could increase PO activity as well as serine proteinase activity suggesting that the rPmSnake activates the proPO system via serine proteinase cascade. PMID- 27693193 TI - Comparative transcriptomics in three ladybird species supports a role for immunity in invasion biology. AB - The spread of the invasive harlequin ladybird (Harmonia axyridis) in Europe is accompanied by the decline of the native and non-invasive two-spotted ladybird (Adalia bipunctata). Here we show that microsporidia carried by H. axyridis can kill A. bipunctata following the oral uptake of spores, suggesting that their horizontal transmission via intraguild predation may help the invader to outcompete its native competitor. The native seven-spotted ladybird (Coccinella septempunctata) is thought to be less susceptible both to the spread of H. axyridis and to its microsporidia. To investigate whether the distinct levels of pathogen susceptibility in these three ladybird species are determined by their immune systems, we compared the immunity-related transcriptomes of untreated beetles and beetles challenged with suspensions of bacteria and yeast. We found that H. axyridis carries three and four times as many genes encoding antimicrobial peptides representing the attacin, coleoptericin and defensin families than C. septempunctata and A. bipunctata, respectively. Gene expression studies following the injection of bacteria and yeasts into beetles revealed that members of these three antimicrobial peptide families are also induced more strongly in H. axyridis than C. septempunctata or A. bipunctata. Our results therefore support the hypothesis that a superior immune system promotes the performance of invasive species. PMID- 27693195 TI - Speech outcomes in Parkinson's disease after subthalamic nucleus deep brain stimulation: A systematic review. AB - Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is effective in reducing motor symptoms for many individuals with Parkinson's disease (PD). However, STN DBS does not appear to influence speech in the same way, and may result in a variety of negative outcomes for people with PD (PWP). A high degree of inter-individual variability amongst PWP regarding speech outcomes following STN DBS is evident in many studies. Furthermore, speech studies in PWP following STN DBS have employed a wide variety of designs and methodologies, which complicate comparison and interpretation of outcome data amongst studies within this growing body of research. An analysis of published evidence regarding speech outcomes in PWP following STN DBS, according to design and quality, is missing. This systematic review aimed to analyse and coalesce all of the current evidence reported within observational and experimental studies investigating the effects of STN DBS on speech. It will strengthen understanding of the relationship between STN DBS and speech, and inform future research by highlighting methodological limitations of current evidence. PMID- 27693194 TI - Gait function and locus coeruleus Lewy body pathology in 51 Parkinson's disease patients. AB - INTRODUCTION: Gait impairment in Parkinson's Disease (PD) is often severely disabling, yet frequently remains refractory to treatment. The locus coeruleus (LC) has diffuse noradrenergic projections that are thought to play a role in gait function. Enhancement of norepinephrine transmission may improve gait in some PD patients. We hypothesized that the severity of PD pathology, and more specifically, Lewy bodies and neuronal loss in the LC, would correlate with the severity of gait dysfunction in PD. METHODS: Autopsy data from 51 patients, collected through the Morris K. Udall Parkinson's Disease Research Center, were correlated with clinical gait-related measures, including individual Unified Parkinson's Disease Rating Scale (UPDRS) Part II and III questions, total UPDRS Part III scores, and timed up-and-go speed (TUG). RESULTS: Neither the presence nor degree of Lewy body pathology in the LC on autopsy was associated with a higher UPDRS part III gait score. LC tau deposition and frontal Lewy body deposition were not correlated with any of the assessed gait measures. The degree of Lewy body pathology, independent of Braak stage, was positively associated with the severity of motor symptoms overall (UPDRS Part III total score). CONCLUSION: Neither the degree of Lewy body nor tau pathology in the LC is associated with severity of gait disorders in PD. This finding may have implications for targeted noradrenergic therapies in patients with refractory gait disorders.

PMID- 27693197 TI - Multiparametric imaging of brain hemodynamics and function using gas-inhalation MRI. AB - Diagnosis and treatment monitoring of cerebrovascular diseases routinely require hemodynamic imaging of the brain. Current methods either only provide part of the desired information or require the injection of multiple exogenous agents. In this study, we developed a multiparametric imaging scheme for the imaging of brain hemodynamics and function using gas-inhalation MRI. The proposed technique uses a single MRI scan to provide simultaneous measurements of baseline venous cerebral blood volume (vCBV), cerebrovascular reactivity (CVR), bolus arrival time (BAT), and resting-state functional connectivity (fcMRI). This was achieved with a novel, concomitant O2 and CO2 gas inhalation paradigm, rapid MRI image acquisition with a 9.3min BOLD sequence, and an advanced algorithm to extract multiple hemodynamic information from the same dataset. In healthy subjects, CVR and vCBV values were 0.23+/-0.03%/mmHg and 0.0056+/-0.0006%/mmHg, respectively, with a strong correlation (r=0.96 for CVR and r=0.91 for vCBV) with more conventional, separate acquisitions that take twice the scan time. In patients with Moyamoya syndrome, CVR in the stenosis-affected flow territories (typically anterior-cerebral-artery, ACA, and middle-cerebral-artery, MCA, territories) was significantly lower than that in posterior-cerebral-artery (PCA), which typically has minimal stenosis, flow territories (0.12+/-0.06%/mmHg vs. 0.21+/-0.05%/mmHg, p<0.001). BAT of the gas bolus was significantly longer (p=0.008) in ACA/MCA territories, compared to PCA, and the maps were consistent with the conventional contrast-enhanced CT perfusion method. FcMRI networks were robustly identified from the gas-inhalation MRI data after factoring out the influence of CO2 and O2 on the signal time course. The spatial correspondence between the gas-data derived fcMRI maps and those using a separate, conventional fcMRI scan was excellent, showing a spatial correlation of 0.58+/-0.17 and 0.64+/-0.20 for default mode network and primary visual network, respectively. These findings suggest that advanced gas-inhalation MRI provides reliable measurements of multiple hemodynamic parameters within a clinically acceptable imaging time and is suitable for patient examinations.

In the present study we show that an IPNV-carrier cell line (EPCIPNV) can induce an antiviral state in fresh EPC by co-cultivating both cell types in three different ways: a "droplet" culture system, a plastic chamber setup, and a transmembrane (Transwell(r)) system. All three cell co-culture methods were proven useful to study donor/target cell interaction. Naive EPC cells grown in contact with EPCIPNV cells develop resistance to VHSV superinfection. The transmembrane system seems best suited to examine gene expression in donor and target cells separately. Our findings point to the conclusion that one or more soluble factors produced by the IPNV carrier culture induce the innate immune response within the target cells. This antiviral response is associated to the up-regulation of interferon (ifn) and mx gene expression in target EPC cells. To our knowledge this is the first article describing co-culture systems to study the interplay between virus-carrier cells and naive cells in fish.

AB - Flavobacterium psychrophilum (Fp) is the causative agent of bacterial cold water disease (BCWD) which causes appreciable economic losses in rainbow trout aquaculture. We previously reported development of a genetic line, designated ARS Fp-R that exhibits higher survival relative to a susceptible line, designated ARS Fp-S, following either laboratory or natural on-farm challenge. The objectives of this study were to determine the temporal kinetics of gene expression between experimentally-challenged ARS-Fp-R and ARS-Fp-S fish and the correlation between gene expression and pathogen load. We developed a GeXP multiplex RT-PCR assay to simultaneously examine expression of immune-relevant genes, concentrating on tumor necrosis factor and interleukin-1 ligand/receptor systems and acute phase response genes. Spleen tissue was sampled at 6 h, 24 h, 48 h and 144 h post challenge and pathogen load quantified by qPCR. Transcript abundance of cytokine genes tnfa1, tnfa2, tnfa3, il1b1, il1b2, il11a; acute phase response genes saa and drtp1; and putative cytokine receptors il1r1-like-b, il1r2, tnfrsf1a, tnfrsf9, tnfrsf1a-like-b increased following challenge while the transcript abundance of il1r-like-1 and tnfrsf1a-like-a decreased compared to PBS-injected line-matched control fish. Principal component analysis identified transcript levels of genes il1r-like-1 and tnfrsf1a-like-a as exhibiting differential expression between genetic lines. In summary, Fp i.p. injection challenge elicited a proinflammatory cytokine gene expression response in the spleen, with ARS-Fp-R line fish exhibiting modestly higher basal expression levels of several putative cytokine receptors. This study furthers the understanding of the immune response following Fp challenge and differences in gene expression associated with selective breeding for disease resistance. PMID- 27693198 TI - Effects of tissue susceptibility on brain temperature mapping. AB - A method for mapping of temperature over a large volume of the brain using volumetric proton MR spectroscopic imaging has been implemented and applied to 150 normal subjects. Magnetic susceptibility-induced frequency shifts in gray- and white-matter regions were measured and included as a correction in the temperature mapping calculation. Additional sources of magnetic susceptibility variations of the individual metabolite resonance frequencies were also observed that reflect the cellular-level organization of the brain metabolites, with the most notable differences being attributed to changes of the N-Acetylaspartate resonance frequency that reflect the intra-axonal distribution and orientation of the white-matter tracts with respect to the applied magnetic field. These metabolite-specific susceptibility effects are also shown to change with age. Results indicate no change of apparent brain temperature with age from 18 to 84 years old, with a trend for increased brain temperature throughout the cerebrum in females relative for males on the order of 0.1 degrees C; slightly increased temperatures in the left hemisphere relative to the right; and a lower temperature of 0.3 degrees C in the cerebellum relative to that of cerebral white matter. This study presents a novel acquisition method for noninvasive measurement of brain temperature that is of potential value for diagnostic purposes and treatment monitoring, while also demonstrating limitations of the measurement due to the confounding effects of tissue susceptibility variations. PMID- 27693201 TI - Dietary choline deficiency and excess induced intestinal inflammation and alteration of intestinal tight junction protein transcription potentially by modulating NF-kappaB, STAT and p38 MAPK signaling molecules in juvenile Jian carp. AB - This study investigated the effects of choline on intestinal mucosal immune and the possible mechanisms in fish by feeding juvenile Jian carp (Cyprinus carpio var. Jian) with graded levels of dietary choline (165-1820 mg/kg diet) for 65 days. The results firstly showed that choline deficiency induced inflammatory infiltration in the proximal intestine (PI), mid intestine (MI) and distal intestine (DI) of fish. Meanwhile, compared with the optimal choline group, choline deficiency decreased the activities of lysozyme and acid phosphatase, contents of complement 3 and IgM in the intestine, downregulated the mRNA levels of antimicrobial peptides (liver-expressed antimicrobial peptide (LEAP) 2A and defensin-3 in the PI and MI, LEAP-2B and hepcidin in the PI, MI and DI), anti inflammatory cytokines (interleukin (IL) 10 and transforming growth factor beta2 in the PI, MI and DI), and signaling molecule IkappaB in the PI, MI and DI; while upregulated the mRNA levels of pro-inflammatory cytokines (IL-6a and tumor necrosis factor alpha in the MI and DI, interferon gamma2b in the PI and MI, IL 1beta and IL-6b in the PI, MI and DI), and signaling molecules (Toll-like receptor 4 in the MI, myeloid differentiation primary response 88 in the PI and MI, Janus kinase 3 and tyrosine kinase 2 in the MI and DI, nuclear factor kappa B (NF-kappaB), signal transducers and activators of transcription (STAT) 4 and STAT5 in the PI, MI and DI) of juvenile Jian carp, further indicating that choline deficiency caused inflammation and immunity depression in the intestine of fish. But choline deficiency decreased the PI IL-6a mRNA level, and increased the DI LEAP-2A and defensin-3 mRNA levels with unknown reasons. Furthermore, dietary choline deficiency downregulated mRNA levels of tight junction (TJ) proteins (claudin 3c in the PI and MI, claudin 7, claudin 11 and occludin in the PI, MI and DI) and signaling molecule mitogen-activated protein kinases p38 in the PI, MI and DI of juvenile Jian carp, whereas upregulated the mRNA levels of claudin 3b in the MI and DI, and claudin 3c in the DI. Moreover, the excessive choline exhibited negative effects on intestinal immunity and TJ proteins that were similar to the choline deficiency. In summary, dietary choline deficiency or excess caused the depression of intestinal mucosal immune by inducing inflammation and dysfunction of the intestinal physical barrier, and regulating related signaling molecules of fish. PMID- 27693202 TI - Effect of 4-nonylphenol on the immune response of the Pacific oyster Crassostrea gigas following bacterial infection with Vibrio campbellii. AB - The xenoestrogen 4-nonylphenol (NP) is a ubiquitous aquatic pollutant and has been shown to impair reproduction, development, growth and, more recently, immune function in marine invertebrates. We investigated the effects of short-term (7 d) exposure to low (2 MUg l-1) and high (100 MUg l-1) levels of NP on cellular and humoral elements of the innate immune response of Crassostrea gigas to a bacterial challenge. To this end, we measured 1) total hemocyte counts (THC), 2) relative transcript abundance of ten immune-related genes (defh1, defh2, bigdef1, bigdef2, bpi, lysozyme-1, galectin, C-type lectin 2, timp, and transglutaminase) in the hemocytes, gill and mantle, and 3) hemolymph plasma lysozyme activity, following experimental Vibrio campbellii infection. Both low and high levels of NP were found to repress a bacteria-induced increase in THC observed in the control oysters. While several genes were differentially expressed following bacterial introduction (bigdef2, bpi, lysozyme-1, timp, transglutaminase), only two genes (bpi in the hemocytes, transglutaminase in the mantle) exhibited a different bacteria-induced expression profile following NP exposure, relative to the control oysters. Independently of infection-status, exposure to NP also altered mRNA transcript abundance of several genes (bpi, galectin, C-type lectin 2) in naive, saline-injected oysters. Finally, plasma lysozyme activity levels were significantly higher in low dose NP-treated oysters (both naive and bacteria challenged) relative to control oysters. Combined, these results suggest that exposure to ecologically-relevant (low) and extreme (high) levels of NP can alter both cellular and humoral elements of the innate immune response in C. gigas, an aquaculture species of global economic importance. PMID- 27693203 TI - Comparison of total costs between internal fixation and hemiarthroplasty for displaced femoral neck fractures. AB - BACKGROUND: There is very little information on the costs of different surgeries for displaced femoral neck fractures. This study aimed to compare the costs between internal fixation and hemiarthroplasty (HA) in the treatment of displaced femoral neck fracture. METHOD: A total of 142 patients aged 65 years or older who had been randomized into internal fixation group (n = 70) or HA group (n = 72) were followed for 2 years. Cost data was collected through hospitalization information, cost diary and telephone interview. Sensitivity analysis was performed for missing diaries. The total costs were collected and compared between the two groups. RESULTS: All diaries were completed by 69.7% of patients. The mean costs of primary treatment were significantly lower for internal fixation (CNY 21,631) compared with HA (CNY 51,641) (p < 0.001). The mean post discharge costs were similar for both procedures: CNY 37,377 for internal fixation and CNY 34,981 for HA (p = 0.640). The mean total costs for internal fixation were CNY 59,008, which was significantly lower than the mean total costs of CNY 86,622 for HA (p = 0.002). CONCLUSION: Although the post-discharge costs of internal fixation were slightly higher, the total costs were still lower than for HA due to great variance in costs of primary treatment. In China, internal fixation may be less costly than HA for displaced femoral neck fracture treatment.

AB - To address the challenging health care needs of the population served by an urban academic medical center, we developed the Johns Hopkins Community Health Partnership (J-CHiP), a novel care coordination program that provides services in homes, community clinics, acute care hospitals, emergency departments, and skilled nursing facilities. This case study describes a comprehensive program that includes: a community-based intervention using multidisciplinary care teams that work closely with the patient's primary care provider; an acute care intervention bundle with collaborative team-based care; and a skilled nursing facility intervention emphasizing standardized transitions and targeted use of care pathways. The program seeks to improve clinical care within and across settings, to address the non-clinical determinants of health, and to ultimately improve healthcare utilization and costs. The case study introduces: a) main program features including rationale, goals, intervention design, and partnership development; b) illness burden and social barriers of the population contributing to care challenges and opportunities; and c) lessons learned with steps that have been taken to engage both patients and providers more actively in the care model. Urban health systems, including academic medical centers, must continue to innovate in care delivery through programs like J-CHiP to meet the needs of their patients and communities.

PMID- 27693206 TI - Randomized Evidence for Reduction of Perioperative Mortality: An Updated Consensus Process. AB - OBJECTIVE: Of the 230 million patients undergoing major surgical procedures every year, more than 1 million will die within 30 days. Thus, any nonsurgical interventions that help reduce perioperative mortality might save thousands of lives. The authors have updated a previous consensus process to identify all the nonsurgical interventions, supported by randomized evidence, that may help reduce perioperative mortality. DESIGN AND SETTING: A web-based international consensus conference. PARTICIPANTS: The study comprised 500 clinicians from 61 countries. INTERVENTIONS: A systematic literature search was performed to identify published literature about nonsurgical interventions, supported by randomized evidence, showing a statistically significant impact on mortality. A consensus conference of experts discussed eligible papers. The interventions identified by the conference then were submitted to colleagues worldwide through a web-based survey. MEASUREMENTS AND MAIN RESULTS: The authors identified 11 interventions contributing to increased survival (perioperative hemodynamic optimization, neuraxial anesthesia, noninvasive ventilation, tranexamic acid, selective decontamination of the gastrointestinal tract, insulin for tight glycemic control, preoperative intra-aortic balloon pump, leuko-depleted red blood cells transfusion, levosimendan, volatile agents, and remote ischemic preconditioning) and 2 interventions showing increased mortality (beta-blocker therapy and aprotinin). Interventions then were voted on by participating clinicians. Percentages of agreement among clinicians in different countries differed significantly for 6 interventions, and a variable gap between evidence and clinical practice was noted. CONCLUSIONS: The authors identified 13 nonsurgical interventions that may decrease or increase perioperative mortality, with variable agreement by clinicians. Such interventions may be optimal candidates for investigation in high-quality trials and discussion in international guidelines to reduce perioperative mortality. PMID- 27693211 TI - Inhibition of SUMO-specific protease 1 induces apoptosis of astroglioma cells by regulating NF-kappaB/Akt pathways. AB - SUMO-specific protease 1 (SENP1) is an important regulation protease in the protein desumoylation, which was shown to have a prooncogenicrole in many types of cancer. However, the mechanism of action for SENP1 in astrocytoma is not yet clear. Astrocytoma is the most frequent one among various neurogliomas, of which a subtype known as glioblastoma multiforme (GBM) is the most malignant brain glioma and seriously influences the life quality of the patients. In this study, the expression of SENP1 was detected in 28 cases of various grades of astrocytoma and 6 cases of normal human tissues. The results showed that the expression of SENP1 was positively correlated with the malignant grades. Besides, the NF-kappaB and Akt signaling pathways in GBM tissues were activated. Cytological experiments indicated that knock-down of endogenous SENP1 promoted cell apoptosis. Further research confirmed that downexpression of SENP1 could inhibit the phosphorylation of IkappaBalpha and Akt, and also the expression of its downstream regulation factors Bcl-xL and cyclinD1. These results delineate a key role for SENP1 in astrocytoma development, suggesting it may be a potential new therapeutic target inastrocytoma. PMID- 27693212 TI - PRDM14 inhibits 293T cell proliferation by influencing the G1/S phase transition. AB - PRDM14 (PRDI-BF1 and RIZ domain-containing 14), a transcription factor, plays important roles in primordial germ cell specification and embryonic stem cell pluripotency, and supports the maintenance of self-renewal by promoting the expression of stem cell markers while also repressing the expression of differentiation factors. As a proto-oncogene, the ectopic expression of PRDM14 can enhance breast cell growth and reduce breast cell sensitivity to chemotherapeutic drugs. Conversely, knockdown of PRDM14 expression induces apoptosis in breast cancer cells and restores their sensitivity to chemotherapeutic drugs. Here, we sought to identify the role of PRDM14 in 293T cells. PRDM14-infected 293T cells exhibited an abnormal morphology, and we found that ectopic expression of PRDM14 inhibits colony formation, cell proliferation and metastasis. In addition, our data indicated that PRDM14 influences the G1/S phase transition of 293T cells by inducing the expression of cell cycle regulators. In conclusion, these results showed that PRDM14 inhibits 293T cell proliferation by influencing the G1/S phase transition and impacts cell migration by regulating the level of MMP/TIMP expression, thus mediating extracellular matrix degradation. PMID- 27693213 TI - MMP 1 circulating levels and promoter polymorphism in risk prediction of coronary artery disease in asymptomatic first degree relatives. AB - Coronary artery disease (CAD) remains to be the prominent health problem in India, and its incidence is growing in developing countries as well. Matrix metalloproteinase 1 (MMP 1) is highly expressed in disruption-prone shoulder regions of the fibrous plaques. The present study aims to investigate association of MMP 1 gene polymorphisms (-1607 1G/2G) and serum circulating levels with CAD. The study includes 300 CAD patients, 100 FDRS, and 300 controls. ELISA and PCR RFLP were performed to determine MMP 1 serum levels and genotypes respectively. MMP1 levels were high in CAD patients, followed by FDRS compared to controls (2.15+/-1.2ng/ml; 1.46+/-1.04ng/ml and 0.96+/-0.53ng/ml) respectively. ROC analysis showed the AUC at 95% CI of serum MMP-1 to be 0.83 and 0.73-0.94, respectively. The optimal cut-off point (sensitivity; specificity) of serum MMP 1 was >1.5ng/ml (0.74; 0.90). The 2G/2G genotype was associated with high MMP 1 circulating levels in CAD patients, and a similar trend was observed in FDRS and controls. The pre-mRNA secondary structure of the 2G allele is much more stable than 1G allele. Our results suggest MMP 1 serum levels and polymorphism as potential independent prognostic markers for future cardiovascular events. These may also help to stratify CAD patients and to identify susceptibility for CAD in asymptomatic healthy FDRS. PMID- 27693214 TI - Identification of the impact on T- and B- cell epitopes of human papillomavirus type-16 E6 and E7 variant in Southwest China. AB - Cervical cancers almost are infected by human papillmavirus (HPV), encoding E6 and E7 oncoproteins which are regard as ideal targets on the mechanism of this disease and development of vaccines. HLA (human leukocyte antigen) participates in the local immune response to prevent tumor invasion and progression. But due to highly polymorphism of HLA, prediction shows its importance in this study. More effective immunoinformatics was used for predicting epitopes from HPV-16 E6 and E7, including T- and B-cell epitopes. Eight substitutions are detected. Specifically speaking, for HLA-I, HLA-A*33:03 (26), HLA-B*13:01 (14), HLA-C*03:02 (5) for E6 and HLA-A*02:01 (6), HLA-B*40:01 (5), HLA-C*03:04 (4) for E7 are most frequency. Epitope 41-48EVYDFAFR for HLA-A*33:03 (0.1) for E6 has best binding affinity, as well as HLA*02:01 and HLA-B*40:01 (0.2) for E7. The mutations of D25E and L83V of E6 and N29S of E7 produce new epitopes, and the percentile values change with them. For HLA-II, seventeen epitopes in the reference at percentile value from 0.22 to 4.76, while in variant from 0.22 to 4.96. For the B cell epitopes, three most potent epitopes for E6 were listed, and N29S lead the growth of score from 0.81 to 0.83. In summary, E640-55REVYDFAFRDLCIVYR and E711 22YMLDLQPETTDL are the important regions, containing the majority of predicted epitopes. E6 72-83 for HLA-A*02:01 and E6 74-84 for HLA-B*15:02 maybe are the new direct for therapeutic vaccine aimed at L83V variants. HLA-DRB1*15:02 is better binder with T cell in our HLA class II. It is a systematic, detail recognition for T- and B-cell epitopes of HPV-16 E6 and E7 from Southwest China, which may be helpful to design vaccines specifically for women in Southwest China and testing methods specifically for this region. The results of our study may contribute to future researches on vaccines improvement, or screening methods for a particular population.

AB - Modulating deformation mechanism through manipulating morphological parameters of scaffold internal pore architecture provides potential to tailor the overall mechanical properties under physiological loadings. Whereas cells sense local strains, cell differentiation is also impressed by the elastic deformations. In this paper, structure-property relations were developed for Ti6-Al-4V scaffolds designed based on triply periodic minimal surfaces. 10mm cubic scaffolds composed of 5*5*5 unit cells formed of F-RD (bending dominated) and I-WP (stretching dominated) architectures were additively manufactured at different volume fractions and subjected to compressive tests. The first stages of deformation for stretching dominated structure, was accompanied by bilateral layer-by-layer failure of unit cells owing to the buckling of micro-struts, while for bending dominated structure, namely F-RD, global shearing bands appeared since the shearing failure of struts in the internal architecture. Promoted mechanical properties were found for stretching dominated structure since the global orientation of struts were parallel to loading direction while inclination of struts diminished specific properties for bending dominated structure. Moreover, elastic-plastic deformation was computationally studied by applying Johnson-Cook damage model to the voxel-based models in FE analysis. Scaling analysis was performed for mechanical properties with respect to the relative density thereby failure mechanism was correlated to the constants of power law describing mechanical properties. PMID- 27693218 TI - MiR-383 inhibits proliferation, migration and angiogenesis of glioma-exposed endothelial cells in vitro via VEGF-mediated FAK and Src signaling pathways. AB - Malignant glioma is undoubtedly the most vascularized tumor of central nervous system. Angiogenesis, playing a predominant role in tumor progression, is widely considered as a key point of tumor treatment. The aim of this study was to investigate the potential effects of miR-383 on proliferation, migration, tube formation and angiogenesis of glioma-exposed endothelial cells (GECs) in vitro and to further elucidate its possible molecular mechanisms. The expression of miR 383 in GECs was significantly downregulated compared with that in normal endothelial cells (ECs). Overexpression of miR-383 dramatically inhibited the proliferation, migration, tube formation and spheroid-based angiogenesis of GECs in vitro. Dual-luciferase reporter results demonstrated vascular endothelial growth factor (VEGF) is a target gene of miR-383. Furthermore, overexpression or silencing of either miR-383 or VEGF was performed simultaneously to further clarify that miR-383 inhibited proliferation, migration and angiogenesis of GECs in vitro by targeting VEGF. Finally, VEGF/VEGFR2-mediated FAK and Src signaling pathways might contribute to anti-angiogenesis of GECs. In conclusion, our present study indicated that miR-383 inhibits proliferation, migration and angiogenesis of GECs in vitro via VEGF/VEGFR2-mediated FAK and Src signaling pathways, which would draw growing attention to miR-383c as a potential therapeutical target of glioma. PMID- 27693219 TI - FhCaBP1 (FH22): A Fasciola hepatica calcium-binding protein with EF-hand and dynein light chain domains. AB - FH22 has been previously identified as a calcium-binding protein from the common liver fluke, Fasciola hepatica. It is part of a family of at least four proteins in this organism which combine an EF-hand containing N-terminal domain with a C terminal dynein light chain-like domain. Here we report further biochemical properties of FH22, which we propose should be renamed FhCaBP1 for consistency with other family members. Molecular modelling predicted that the two domains are linked by a flexible region and that the second EF-hand in the N-terminal domain is most likely the calcium ion binding site. Native gel electrophoresis demonstrated that the protein binds both calcium and manganese ions, but not cadmium, magnesium, strontium, barium, cobalt, copper(II), iron (II), nickel, zinc, lead or potassium ions. Calcium ion binding alters the conformation of the protein and increases its stability towards thermal denaturation. FhCaBP1 is a dimer in solution and calcium ions have no detectable effect on the protein's ability to dimerise. FhCaBP1 binds to the calmodulin antagonists trifluoperazine and chlorpromazine. Overall, the FhCaBP1's biochemical properties are most similar to FhCaBP2 a fact consistent with the close sequence and predicted structural similarity between the two proteins. PMID- 27693220 TI - Screening and characterization of apical membrane antigen 1 interacting proteins in Eimeria tenella. AB - Avian coccidiosis is a widespread and economically significant disease of poultry. It is an enteric disease caused by several protozoan Eimeria species. Eimeria belongs to the phylum Apicomplexa, which exhibits an unusual mechanism of host cell invasion. During invasion of host cells, the protein apical membrane antigen 1 (AMA1) is essential for invasion of Toxoplasma gondii and Plasmodium. Contrary to the roles of AMA1 during host cell invasion in T. gondii and Plasmodium, the precise functions of Eimeria AMA1 (EtAMA1) are unclear. In order to study the functions of EtAMA1, a yeast two-hybrid cDNA library was constructed from E. tenella sporozoites. The EtAMA1 ectodomain was cloned into the pGBKT7 vector to construct the bait plasmid pGBKT7- EtAMA1. Autoactivation and toxicity of the bait protein in yeast cells were tested by comparison with the pGBKT7 empty vector. Expression of the bait protein was detected by western blots. The bait plasmid pGBKT7-EtAMA1 was used to screen yeast two-hybrid cDNA library from E. tenella sporozoites. After multiple screenings with high-screening-rate medium and exclusion of false-positive plasmids, positive preys were sequenced and analyzed using BLAST. We obtained 14 putative EtAMA1-interacting proteins including E. tenella acidic microneme protein2 (EtMIC2), E. tenella putative cystathionine beta-synthase, E. tenella Eimeria-specific protein, four E. tenella conserved hypothetical proteins (one in the serine/threonine protein kinase family) and seven unknown proteins. Gene Ontology analysis indicated that two known proteins were associated with metabolic process, pyridoxal phosphate binding and protein phosphorylation. Functional analysis indicated EtMIC2 was implicated in parasite motility, migration, recognition and invasion of host cells. The data suggested that EtAMA1 may be important during host cell invasion, but also involved in other biological processes. PMID- 27693221 TI - Trichomonas gallinae: Prevalence and molecular characterization from pigeons in Minoufiya governorate, Egypt. AB - Trichomonas gallinae infects the upper digestive tract of pigeons. It is transmitted from mother to young squabs by feeding crop milk. Generally, infection resulted in severe mortalities in young birds. In this study, we examined 3315 pigeons of different ages from the Minoufiya governorate for the clinical infection by T. gallinae. The infection was confirmed in infected birds by microscopical examination of oral swabs, histopathological examination, and PCR of the ITS1/5.8S/ITS2 gene. The prevalence was 63 (1.9%). The parasite was found in 35 (2.04%) from Ashmoun, 15 (1.66%) from Minoof, 8 (1.6%) from Quesna, and 5 (2.5%) from El-Shohada birds. The infection was mainly detected in squabs 60 (1.8%). The sequence of T. gallinae ITS1/5.8S/ITS2 gene from Egypt has high nucleotide sequence identity (up to100%) to T. gallinae from pigeon of USA, Austria, Canada, and Spain. The sequence belongs to genotype B of T. gallinae. Histopathological examination presented the parasites in crop, liver, larynx, and trachea as poorly eosinophilic bodies with severe inflammatory cell infiltration. This is the first study to present the prevalence and genotype of T. gallinae from Minoufiya governorate, Egypt. PMID- 27693222 TI - Hepatic injury associated with Trypanosoma cruzi infection is attenuated by treatment with 15-deoxy-Delta12,14 prostaglandin J2. AB - Trypanosoma cruzi, the etiological agent of Chagas' disease, causes an intense inflammatory response in several tissues, including the liver. Since this organ is central to metabolism, its infection may be reflected in the outcome of the disease. 15-deoxy-Delta12,14 prostaglandin J2 (15dPGJ2), a natural agonist of peroxisome-proliferator activated receptor (PPAR) gamma, has been shown to exert anti-inflammatory effects in the heart upon T. cruzi infection. However, its role in the restoration of liver function and reduction of liver inflammation has not been studied yet. BALB/c mice were infected with T. cruzi. The effects of in vivo treatment with 15dPGJ2 on liver inflammation and fibrosis, as well as on the GOT/GPT ratio were studied and the role of NF-kappaB pathway on 15dPGJ2-mediated effects was analysed. 15dPGJ2 reduced liver inflammatory infiltrates, proinflammatory enzymes and cytokines expression, restored the De Ritis ratio values to normal, reduced the deposits of interstitial and perisinusoidal collagen, reduced the expression of the pro-fibrotic cytokines and inhibited the translocation of the p65 NF-kappaB subunit to the nucleus. Thus, we showed that 15dPGJ2 is able to significantly reduce the inflammatory response and fibrosis and reduced enzyme markers of liver damage in mice infected with T. cruzi. PMID- 27693223 TI - Experimental infection of calves with Haemonchus placei or Haemonchus contortus: Assessment of clinical, hematological and biochemical parameters and histopathological characteristics of abomasums. AB - The present study had the primary objective of evaluating clinical, hematological and biochemical parameters, as well as observing anatomical and histopathological characteristics of abomasums, from calves prime-infected with Haemonchus contortus or H. placei. Ten male Holstein newborns were subdivided in three groups (GI placebo; GII infected with H. contortus; GIII inoculated with H. placei). Eye mucosa staining was evaluated. Hematological and biochemical tests were performed on animals. The euthanasia of all ten experimental calves was performed on the 42nd day post-inoculation. Fragments were collected from each of all 10 abomasums for histopathological analysis. Discrete submandibular edema was diagnosed in animals from both infected groups (H. contortus or H. placei). However, there were no significant changes (P > 0.05) in the color of the ocular mucosa of calves from all three experimental groups across the entire experimental period. Hematological and biochemical changes diagnosed on animals could not be linked to infections by species of Haemonchus spp. Regarding histopathological exams, it was possible to diagnose hypertrophy, hyperplasia, binucleated cells, inflammatory infiltrate, multifocal hemorrhage and edema in abomasums from calves of both groups infected with H. placei and H. contortus. It can, thus, be concluded that not only are calves susceptible to infections by both Haemonchus species, but they can also present clinical changes and similar anatomic histopathological lesions independent of being infected by Haemonchus placei or Haemonchus contortus. These results reflect a negative effect on helminth control by mixed grazing between sheep and cattle, especially when using calves. PMID- 27693224 TI - Standardizing dose prescriptions: An ASTRO white paper. AB - This white paper recommends the standardization (content and presentation order) of several "key components" of the radiation therapy prescription to facilitate accurate communication between radiation therapy care providers. The rationale, other similar efforts, and detailed considerations are described. In brief, the Task Force recommends that the prescription's "elements" include: treatment site, method of delivery, dose per fraction, total number of fractions, total dose (eg, right breast, tangent photons, 267 cGy * 16 = 4272 cGy). A similar formalism is recommended for brachytherapy (eg, cervix, Ir-192 brachytherapy, 600cGy * 5 = 3000 cGy) and other modalities. The white paper also considers future directions for other items such as the simulation order, treatment planning objectives, prescription point or volume, treatment schedule, localization imaging, laboratory monitoring, concurrent chemotherapy, patient instructions for treatment, etc. The intent of this white paper is to facilitate accurate communication among providers to support safe practice as well as to guide vendors in product development that is consistent with this standard prescription.

AB - PURPOSE: Patients with locally recurrent prostate cancer after definitive prostate brachytherapy have few evidence-based salvage options. We evaluate the efficacy and treatment-related side-effects of salvage external-beam radiotherapy (EBRT) after definitive prostate brachytherapy (PBT). METHODS AND MATERIALS: Eleven patients previously treated with definitive PBT and with biopsy-proven local-only recurrence received salvage reirradiation with EBRT. Genitourinary (GU) function was assessed with International Prostate Symptom Scores. Treatment related toxicities were graded using CTCAE v 4.03. RESULTS: Median follow-up was 26.5 months (range, 1-53.6 months); median age at EBRT salvage was 67 years (range, 61-81 years). Salvage EBRT included the whole pelvis in 8 patients. Two patients were treated with 3D-CRT; 9 underwent IMRT. Five patients (45%) received androgen deprivation therapy concurrent with salvage EBRT as part of long- or short-course hormone therapy. The median prostate dose was 70.2 Gy (range, 64.8 75.6 Gy). Actuarial 3-year overall and biochemical failure-free survival were 77% and 69%, respectively. Five patients (45%) had worsening GU symptoms, and 9 (82%) experienced a decline in erectile function. One patient experienced acute grade 2 GU toxicity. Four patients (36%) experienced late grade >=2 GI/GU toxicities, including 2 who experienced grade 3 toxicities (rectourethral fistula/incontinence, bladder outlet obstruction). No grade 4/5 toxicities were noted. CONCLUSIONS: Our data suggest that salvage EBRT can provide similar disease control and treatment-related toxicity to more established salvage therapies. This approach warrants further investigation on a larger scale. PMID- 27693226 TI - Does intensity or youth affect the neurobiological effect of exercise on major depressive disorder? AB - The purpose of this commentary is to discuss the different neurobiological effects of exercise on major depressive disorder (MDD) in children and adolescents and to provide additional explanations to this well written systematic review. This commentary highlights the effects of exercise on the hypothalamic-pituitary-adrenal (HPA) axis, which plays a crucial role in MDD. We address the questions of whether age and different exercise intensities may provide additional information on the neurobiological effects of acute or chronic exercise on MDD. Previous findings clearly suggest that the etiology of MDD is complex and multifaceted, involving numerous neurobiological systems, which are additionally influenced by these two factors. PMID- 27693227 TI - Appetitive Pavlovian-instrumental Transfer: A review. AB - Reward-related cues are an important part of our daily life as they often influence and guide our actions. This paper reviews one of the experimental paradigms used to study the effects of cues, the Pavlovian to Instrumental Transfer paradigm. In this paradigm, cues associated with rewards through Pavlovian conditioning alter motivation and choice of instrumental actions. The first transfer experiments date back to the 1940s, but only in the last decade has it been fully recognised that there are two types of transfer, specific and general. This paper presents a systematic review of both the neural substrates and the behavioral factors affecting both types of transfer. It also examines the recent application of the paradigm to study the effect of cues on human participants, both in normal and pathological conditions, and the interactions of transfer with drugs of abuse. Finally, the paper analyses the theoretical aspects of transfer to build an overall picture of the phenomenon, from early theories to recent hierarchical accounts. PMID- 27693229 TI - The research domain criteria framework: The case for anterior cingulate cortex. AB - The United States National Institute of Mental Health has recently promoted the Research Domain Criteria framework, which emphasizes the study of neurocognitive constructs that cut across different disorders. These constructs are said to express dimensionally across the population, giving rise to psychopathologies only in the extreme cases where that expression is maladaptive. Inspired by the RDoC framework, we propose that recent insights into the function of anterior cingulate cortex (ACC), a brain area said to be responsible for selecting and motivating extended behaviors, may elucidate the etiology of a diverse array of mental disorders. We argue that ACC function contributes to individual differences in personality traits related to reward sensitivity and persistence, and propose that the maladaptive expression of these traits contributes to multiple mental and neurological disorders. Our discussion is organized around a computational framework that relates the reward processing and control functions of ACC, as revealed by two electrophysiological phenomena called the reward positivity and frontal midline theta oscillations, to a distributed neural system underlying cognitive control.

AB - OBJECTIVE: Eating Disorders (ED) and obesity are suggested to involve a spectrum of self-regulatory control difficulties. Temporal discounting (TD) tasks have been used to explore this idea. This systematic review examines behavioural and neuroimaging TD data in ED and obesity. METHOD: Using PRISMA guidelines, we reviewed relevant articles in MEDLINE, PsycINFO and Embase from inception until 17th August 2016. Studies that reported behavioural differences in TD and/or TD neuroimaging data in ED/obesity were included. RESULTS: Thirty-one studies were included. Limited data suggest that BN, BED and obesity are associated with increased TD, whilst data in AN are mixed. Aberrant neural activity in frontostriatal circuitry is implicated. TD tasks vary widely and TD in ED/obesity may vary according to factors such as illness stage. CONCLUSION: Our findings suggest altered self-regulatory control in ED and obesity. TD tasks are heterogeneous, limiting generalisability of findings. Research into whether TD is multidimensional, along with transdiagnostic neuroimaging research is needed. Assessment of TD may be useful in psychoeducation, outcome prediction and treatment of ED/obesity. PMID- 27693230 TI - Importance of astrocytes for potassium ion (K+) homeostasis in brain and glial effects of K+ and its transporters on learning. AB - Initial clearance of extracellular K+ ([K+]o) following neuronal excitation occurs by astrocytic uptake, because elevated [K+]o activates astrocytic but not neuronal Na+,K+-ATPases. Subsequently, astrocytic K+ is re-released via Kir4.1 channels after distribution in the astrocytic functional syncytium via gap junctions. The dispersal ensures widespread release, preventing renewed [K+]o increase and allowing neuronal Na+,K+-ATPase-mediated re-uptake. Na+,K+-ATPase operation creates extracellular hypertonicity and cell shrinkage which is reversed by the astrocytic cotransporter NKCC1. Inhibition of Kir channels by activation of specific PKC isotypes may decrease syncytial distribution and enable physiologically occurring [K+]o increases to open L-channels for Ca2+, activating [K+]o-stimulated gliotransmitter release and regulating gap junctions. Learning is impaired when [K+]o is decreased to levels mainly affecting astrocytic membrane potential or Na+,K+-ATPase or by abnormalities in its alpha2 subunit. It is enhanced by NKCC1-mediated ion and water uptake during the undershoot, reversing neuronal inactivity, but impaired in migraine with aura in which [K+]o is highly increased. Vasopressin augments NKCC1 effects and facilitates learning. Enhanced myelination, facilitated by astrocytic oligodendrocytic gap junctions also promotes learning.

AB - Amelogenesis is the process of dental enamel formation, leading to the deposition of the hardest tissue in the human body. This process requires the intricate regulation of ion transport and controlled changes to the pH of the developing enamel matrix. The means by which the enamel organ regulates pH during amelogenesis is largely unknown. We identified rare homozygous variants in GPR68 in three families with amelogenesis imperfecta, a genetically and phenotypically heterogeneous group of inherited conditions associated with abnormal enamel formation. Each of these homozygous variants (a large in-frame deletion, a frameshift deletion, and a missense variant) were predicted to result in loss of function. GPR68 encodes a proton-sensing G-protein-coupled receptor with sensitivity in the pH range that occurs in the developing enamel matrix during amelogenesis. Immunohistochemistry of rat mandibles confirmed localization of GPR68 in the enamel organ at all stages of amelogenesis. Our data identify a role for GPR68 as a proton sensor that is required for proper enamel formation. PMID- 27693234 TI - Observations on different resin strategies for affinity purification mass spectrometry of a tagged protein. AB - Co-affinity purification mass spectrometry (CoAP-MS) is a highly effective method for identifying protein complexes from a biological sample and inferring important interactions, but the impact of the solid support is usually not considered in design of such experiments. Affinity purification (AP) experiments typically utilize a bait protein expressing a peptide tag such as FLAG, c-Myc, HA or V5 and high affinity antibodies to these peptide sequences to facilitate isolation of a bait protein to co-purify interacting proteins. We observed significant variability for isolation of tagged bait proteins between Protein A/G Agarose, Protein G Dynabeads, and AminoLink resins. While previous research identified the importance of tag sequence and their location, crosslinking procedures, reagents, dilution, and detergent concentrations, the effect of the resin itself has not been considered. Our data suggest the type of solid support is important and, under the conditions of our experiments, AminoLink resin provided a more robust solid-support platform for AP-MS. PMID- 27693235 TI - The defender against apoptotic cell death 1 gene is required for tissue growth and efficient N-glycosylation in Drosophila melanogaster. AB - How organ growth is regulated in multicellular organisms is a long-standing question in developmental biology. It is known that coordination of cell apoptosis and proliferation is critical in cell number and overall organ size control, while how these processes are regulated is still under investigation. In this study, we found that functional loss of a gene in Drosophila, named Drosophila defender against apoptotic cell death 1 (dDad1), leads to a reduction of tissue growth due to increased apoptosis and lack of cell proliferation. The dDad1 protein, an orthologue of mammalian Dad1, was found to be crucial for protein N-glycosylation in developing tissues. Our study demonstrated that loss of dDad1 function activates JNK signaling and blocking the JNK pathway in dDad1 knock-down tissues suppresses cell apoptosis and partially restores organ size. In addition, reduction of dDad1 triggers ER stress and activates unfolded protein response (UPR) signaling, prior to the activation of JNK signaling. Furthermore, Perk-Atf4 signaling, one branch of UPR pathways, appears to play a dual role in inducing cell apoptosis and mediating compensatory cell proliferation in this dDad1 knock-down model. PMID- 27693233 TI - Recurrent De Novo Dominant Mutations in SLC25A4 Cause Severe Early-Onset Mitochondrial Disease and Loss of Mitochondrial DNA Copy Number. AB - Mutations in SLC25A4 encoding the mitochondrial ADP/ATP carrier AAC1 are well recognized causes of mitochondrial disease. Several heterozygous SLC25A4 mutations cause adult-onset autosomal-dominant progressive external ophthalmoplegia associated with multiple mitochondrial DNA deletions, whereas recessive SLC25A4 mutations cause childhood-onset mitochondrial myopathy and cardiomyopathy. Here, we describe the identification by whole-exome sequencing of seven probands harboring dominant, de novo SLC25A4 mutations. All affected individuals presented at birth, were ventilator dependent and, where tested, revealed severe combined mitochondrial respiratory chain deficiencies associated with a marked loss of mitochondrial DNA copy number in skeletal muscle. Strikingly, an identical c.239G>A (p.Arg80His) mutation was present in four of the seven subjects, and the other three case subjects harbored the same c.703C>G (p.Arg235Gly) mutation. Analysis of skeletal muscle revealed a marked decrease of AAC1 protein levels and loss of respiratory chain complexes containing mitochondrial DNA-encoded subunits. We show that both recombinant AAC1 mutant proteins are severely impaired in ADP/ATP transport, affecting most likely the substrate binding and mechanics of the carrier, respectively. This highly reduced capacity for transport probably affects mitochondrial DNA maintenance and in turn respiration, causing a severe energy crisis. The confirmation of the pathogenicity of these de novo SLC25A4 mutations highlights a third distinct clinical phenotype associated with mutation of this gene and demonstrates that early-onset mitochondrial disease can be caused by recurrent de novo mutations, which has significant implications for the application and analysis of whole exome sequencing data in mitochondrial disease. PMID- 27693236 TI - Bovine epididymal spermatozoa: Resistance to cryopreservation and binding ability to oviductal cells. AB - In this study we examined quality, longevity and ability of epididymal sperm (EP) to bind to oviduct explants (OE) after cooling and cryopreservation. Ejaculated (EJ) and EP sperm from seven bulls were evaluated before, during and after cryopreservation for total (TM), progressive motility (PM), sperm morphology, plasma membrane integrity (PMI) and acrosome integrity (ACI). For longevity, cryopreserved EP, EJ and a third group of cells in which EP spermatozoa were incubated with seminal plasm (SP) for 10 min after thawing (EPP group), were compared, and the groups were analyzed at 0, 3, 6, and 24 h for all parameters. Sperm from each group were co-incubated with OE for 30 min, 6 h, and 24 h for binding evaluation. Data were analyzed by the generalized linear models SAS 9.1 (P < 0.05). After cooling, EP displayed higher TM, higher PMI, and higher ACI (P < 0.05) than EJ. No differences were noted in the percentage of spermatozoa with PMI and AI between EJ and EP for fresh, cooled or cryopreserved sperm. However, a reduction in motility occurred in the EJ sperm after cooling, while in EP group such reduction occurred only after cryopreservation. At 6 h of incubation EP and EPP had higher PMI and ACI than EJ (P < 0.05). The number of spermatozoa bound to OE was similar P > 0.05) for all groups either at 30 min or 24 h. We conclude that EP are more resistant to cooling than EJ, and can bind to OE similarly to EJ. PMID- 27693237 TI - Transcranial Direct Current Stimulation in Mesial Temporal Lobe Epilepsy and Hippocampal Sclerosis. AB - BACKGROUND: Transcranial direct current stimulation (tDCS) has been evaluated in medication refractory epilepsy patients. The results have been inconclusive and protocols have varied between studies. OBJECTIVE: To evaluate the safety and efficacy of two protocols of tDCS in adult patients with mesial temporal lobe epilepsy and hippocampal sclerosis (MTLE-HS). METHODS: This is a randomized placebo-controlled, double-blinded clinical trial, with 3 arms, 3 sessions, 5 sessions and placebo stimulation. Frequency of seizures (SZs), interictal epileptiform discharges (IEDs) and adverse effects (AEs) were registered before and after treatment, and at 30 and 60 days follow-up. Descriptive statistics, k related samples, Friedman's test, and relative risk (RR) estimation were used for analysis. RESULTS: We included twenty-eight subjects (3d n = 12, 5d n = 8, placebo n = 8), 16/28 (57%) men, age 37.8(+/-10.9) years old. There was a significant reduction of the frequency of SZs at one (p = 0.001) and two (p = 0.0001) months following cathodal tDCS compared to baseline in the 3 arms (p = 0.0001). The mean reduction of SZ frequency at two months in both active groups was significantly higher than placebo (-48% vs. -6.25%, p < 0.008). At 3 days ( 43.4% vs. -6.25%, p < 0.007) and 5 days (-54.6% vs. -6.25%, p < 0.010) individual groups showed a greater reduction of SZs. A significant IED reduction effect was found between baseline and immediately after interventions (p = 0.041) in all groups. Side effects were minor. CONCLUSIONS: Cathodal tDCS technique of 3 and 5 sessions decreased the frequency of SZs and IEDs (between baseline and immediately post-tDCS) in adult patients with MTLE-HS compared to placebo tDCS.

AB - PURPOSE: Nanosilver-silicone hydrogel (NAgSiH) composites for contact lenses were synthesized to asses the antimicrobial effects. METHODS: Silicone hydrogel (SiH) films were synthesized followed by impregnation in silver nitrate solutions (10, 20, 30, 40, 60, 80ppm) and in-situ chemical reduction of silver ions using sodium borohydride (NaBH4). The silver nano particles (AgNPS) were identified by UV-vis absorption spectroscopy, Energy-dispersive X-ray spectroscopy (EDX) mapping and EDX spectrum. Physico-mechanical and chemical properties of NAgSIH films were studied. The antimicrobial effect of the hydrogels against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus was evaluated. The numbers of viable bacterial cells on NAgSiH surface or in solution compared to control SiH were examined. RESULTS: The NAgSiH films were successfully synthesized. FTIR results indicated that AgNPS had no effect on the bulk structure of the prepared SiH films. From TGA analysis, NAgSiH(R80) and SiH(R0) films had the same maximum decomposition temperature (404 degrees C). UV vis absorption spectroscopy and EDX mapping and spectrum emphasized that AgNPS were in spherical shape. The maximum absorption wavelength of NAgSiH films were around 400nm. The light transmittance decreased as the concentration of AgNPS increased, but still greater than 90% at wavelength around 555nm. The Young's modulus increased gradually from 1.06MPa of SiH(R0) to highest value 1.38MPa of NAgSiH(R80). AgNPS incorporated into SiH films reduced the bacterial cell growth and prevented colonization. Groups NAgSiH(R60,R80) demonstrated an excellent reduction in bacterial viability in solution and on the SiH surface. CONCLUSIONS: NAgSiH composites were successfully synthesized and possessed an excellent antimicrobial effects. PMID- 27693232 TI - De Novo Truncating Variants in ASXL2 Are Associated with a Unique and Recognizable Clinical Phenotype. AB - The ASXL genes (ASXL1, ASXL2, and ASXL3) participate in body patterning during embryogenesis and encode proteins involved in epigenetic regulation and assembly of transcription factors to specific genomic loci. Germline de novo truncating variants in ASXL1 and ASXL3 have been respectively implicated in causing Bohring Opitz and Bainbridge-Ropers syndromes, which result in overlapping features of severe intellectual disability and dysmorphic features. ASXL2 has not yet been associated with a human Mendelian disorder. In this study, we performed whole exome sequencing in six unrelated probands with developmental delay, macrocephaly, and dysmorphic features. All six had de novo truncating variants in ASXL2. A careful review enabled the recognition of a specific phenotype consisting of macrocephaly, prominent eyes, arched eyebrows, hypertelorism, a glabellar nevus flammeus, neonatal feeding difficulties, hypotonia, and developmental disabilities. Although overlapping features with Bohring-Opitz and Bainbridge-Ropers syndromes exist, features that distinguish the ASXL2-associated condition from ASXL1- and ASXL3-related disorders are macrocephaly, absence of growth retardation, and more variability in the degree of intellectual disabilities. We were also able to demonstrate with mRNA studies that these variants are likely to exert a dominant-negative effect, given that both alleles are expressed in blood and the mutated ASXL2 transcripts escape nonsense-mediated decay. In conclusion, de novo truncating variants in ASXL2 underlie a neurodevelopmental syndrome with a clinically recognizable phenotype. This report expands the germline disorders that are linked to the ASXL genes. PMID- 27693241 TI - The role of the anti-ageing protein Klotho in vascular physiology and pathophysiology. AB - Klotho is an anti-ageing protein that functions in many pathways that govern ageing, like regulation of phosphate homeostasis, insulin signaling, and Wnt signaling. Klotho expression levels and levels in blood decline during ageing. The vascular phenotype of Klotho deficiency features medial calcification, intima hyperplasia, endothelial dysfunction, arterial stiffening, hypertension, and impaired angiogenesis and vasculogenesis, with characteristics similar to aged human arteries. Klotho-deficient phenotypes can be prevented and rescued by Klotho gene expression or protein supplementation. High phosphate levels are likely to be directly pathogenic and are a prerequisite for medial calcification, but more important determinants are pathways that regulate cellular senescence, suggesting that deficiency of Klotho renders cells susceptible to phosphate toxicity. Overexpression of Klotho is shown to ameliorate medial calcification, endothelial dysfunction, and hypertension. Endogenous vascular Klotho expression is a controversial subject and, currently, no compelling evidence exists that supports the existence of vascular membrane-bound Klotho expression, as expressed in kidney. In vitro, Klotho has been shown to decrease oxidative stress and apoptosis in both SMCs and ECs, to reduce SMC calcification, to maintain the contractile SMC phenotype, and to prevent MU-calpain overactivation in ECs. Klotho has many protective effects with regard to the vasculature and constitutes a very promising therapeutic target. The purpose of this review is to explore the etiology of the vascular phenotype of Klotho deficiency and the therapeutic potential of Klotho in vascular disease. PMID- 27693242 TI - A quantitative study on splice variants of N-acylethanolamine acid amidase in human prostate cancer cells and other cells. AB - N-Acylethanolamine acid amidase (NAAA) is a lysosomal enzyme, hydrolyzing various bioactive N-acylethanolamines with a preference for palmitoylethanolamide. Human NAAA mRNA was previously reported to consist of multiple 3'-end splice variants. However, their tissue distributions and roles have not been examined yet. In the present study, we first identified four major splice variants (tentatively referred to as a1, a2, b2, and c2) in a human prostate cancer cell line LNCaP, which were composed of exons 1-11, exons 1-10 and 12, exons 1-9 and 12, and exons 1-8 and 12, respectively. We next developed quantitative polymerase chain reaction methods to individually quantify these NAAA variants as well as collectively measure all the variants. Among various human prostate cancer cells, the total levels of NAAA mRNAs in androgen-sensitive cells like LNCaP were higher than those in androgen-insensitive cells. In all of these prostate cells and other human cells, variants a1 and b2 showed the highest and lowest expression levels, respectively, among the four variants. Interestingly, ratios of the four variants were different by cell type. Variants a1 and a2 encoded the same full length NAAA protein, which was catalytically active, while b2 and c2 were translated to C-terminally truncated proteins. As expressed in HEK293 cells these truncated forms were detected as catalytically inactive precursor proteins, but not as mature forms. These results revealed wide distribution of multiple variants of NAAA mRNA in various human cells and suggested that the proteins from some variants are catalytically inactive. PMID- 27693243 TI - Benzyl isothiocyanate promotes apoptosis of oral cancer cells via an acute redox stress-mediated DNA damage response. AB - Benzyl isothiocyanate (BITC) is a cruciferous vegetable-derived compound with anticancer properties in human cancer cells. However, its anticancer potential and underlying mechanisms remain absent in human oral cancer cells. Results indicate that BITC inhibits growth, promotes G2/M phase arrest and triggers apoptosis of OC2 cells with a minimal toxicity to normal cells. BITC-induced cell death was completely prevented by pretreatment with thiol-containing redox compounds including N-acetyl-l-cysteine (NAC), glutathione (GSH), dithiothreitol, and 2-mercaptoethanol, but not free radical scavengers mito-TEMPO, catalase, apocynin, l-NAME and mannitol. BITC rapidly produced reactive oxygen species and nitric oxide, triggered oxidative DNA damage. BITC effectively decreased the intracellular GSH and GSH/GSSG ratio and redox balance recovery by thiol containing redox compounds, but not by free radical scavengers. Accordingly, redox stresses-DNA damage response (DDR) activated ATM, Chk2, p53, and p21 and subsequently resulted in G2/M phase arrest by inhibiting Cdc2 and cyclin B1. Notably, BITC-induced apoptosis was associated with reduced Mcl-1 and Bcl-2 expression, diminished mitochondrial membrane potential (DeltaPsim), and increased PARP cleavage. These BITC-induced redox stress-mediated DDR and apoptosis could be blocked by NAC and GSH. Therefore, BITC can be a rational drug candidate for oral cancer and acted via a redox-dependent pathway. PMID- 27693244 TI - Impact of DNA repair on the dose-response of colorectal cancer formation induced by dietary carcinogens. AB - Colorectal cancer (CRC) is one of the most frequently diagnosed cancers, which is causally linked to dietary habits, notably the intake of processed and red meat. Processed and red meat contain dietary carcinogens, including heterocyclic aromatic amines (HCAs) and N-nitroso compounds (NOC). NOC are agents that induce various N-methylated DNA adducts and O6-methylguanine (O6-MeG), which are removed by base excision repair (BER) and O6-methylguanine-DNA methyltransferase (MGMT), respectively. HCAs such as the highly mutagenic 2-amino-1-methyl-6 phenylimidazo[4,5-b]pyridine (PhIP) cause bulky DNA adducts, which are removed from DNA by nucleotide excision repair (NER). Both O6-MeG and HCA-induced DNA adducts are linked to the occurrence of KRAS and APC mutations in colorectal tumors of rodents and humans, thereby driving CRC initiation and progression. In this review, we focus on DNA repair pathways removing DNA lesions induced by NOC and HCA and assess their role in protecting against mutagenicity and carcinogenicity in the large intestine. We further discuss the impact of DNA repair on the dose-response relationship in colorectal carcinogenesis in view of recent studies, demonstrating the existence of 'no effect' point of departures (PoDs), i.e. thresholds for genotoxicity and carcinogenicity. The available data support the threshold concept for NOC with DNA repair being causally involved. PMID- 27693245 TI - Ninety-day toxicity and single-dose toxicokinetics study of alpha-glycosyl isoquercitrin in Sprague-Dawley rats. AB - alpha-Glycosyl isoquercitrin (AGIQ) is highly absorbable and has been shown to possess antioxidative properties. Based on a favorable safety profile, it has been confirmed as generally recognized as safe (GRAS) compound by the FDA. Nevertheless, safety and toxicity information for AGIQ is still sparse. Therefore, the aim of this study was to test the safety and toxicokinetics of AGIQ in a 90-day study in 60 male and 60 female Sprague-Dawley rats at dietary doses up to 5%. All animals survived until scheduled euthanasia with no clinical signs of toxicity in any animal. AGIQ was rapidly absorbed with metabolism to quercetin and quercetin glucuronide at all dose levels. Statistically significant changes were noted in some tissue weights and clinical chemistry analytes, without evidence of systemic toxicity. The most prominent finding was systemic dose dependent yellow discoloration of bones of treated animals. However, no changes were observed microscopically, and this observation was concluded as toxicologically insignificant. The overall lack of adverse clinical signs, changes in body weight, feed consumption, clinical pathology parameters, and histopathological endpoints in animals administered AGIQ supports no observable adverse effect levels (NOAEL) of 5.0% in diet for both male and female rats (3461 mg/kg/day and 3867 mg/kg/day, respectively). PMID- 27693240 TI - The impact of cerebrovascular aging on vascular cognitive impairment and dementia. AB - As human life expectancy rises, the aged population will increase. Aging is accompanied by changes in tissue structure, often resulting in functional decline. For example, aging within blood vessels contributes to a decrease in blood flow to important organs, potentially leading to organ atrophy and loss of function. In the central nervous system, cerebral vascular aging can lead to loss of the integrity of the blood-brain barrier, eventually resulting in cognitive and sensorimotor decline. One of the major of types of cognitive dysfunction due to chronic cerebral hypoperfusion is vascular cognitive impairment and dementia (VCID). In spite of recent progress in clinical and experimental VCID research, our understanding of vascular contributions to the pathogenesis of VCID is still very limited. In this review, we summarize recent findings on VCID, with a focus on vascular age-related pathologies and their contribution to the development of this condition. PMID- 27693247 TI - Value of Targeted Epidural Blood Patch and Management of Subdural Hematoma in Spontaneous Intracranial Hypotension: Case Report and Review of the Literature. AB - BACKGROUND: Spontaneous intracranial hypotension (SIH) is a more common than previously noted condition (1-2.5 per 50,000 persons) typically caused by cerebrospinal fluid (CSF) leakage. Initial treatment involves conservative therapies, but the mainstay of treatment for patients who fail conservative management is the epidural blood patch (EBP). Subdural hematoma (SDH) is a common complication occurring with SIH, but its management remains controversial. METHODS: In this report, we discuss a 62-year-old woman who presented with a 5 week history of orthostatic headaches associated with nausea, emesis, and neck pain. Despite initial imaging being negative, the patient later developed classic imaging evidence characteristic of SIH. Magnetic resonance imaging was unrevealing for the source of the CSF leak. Radionuclide cisternography showed possible CSF leak at the right-sided C7-T1 nerve root exit site. After failing a blind lumbar EBP, subsequent targeted EBP at C7-T1 improved the patient's symptoms. Two days later she developed a new headache with imaging evidence of worsening SDH with midline shift requiring burr hole drainage. This yielded sustained symptomatic relief and resolution of previously abnormal imaging findings at 2-month follow-up. RESULTS: A literature review revealed 174 cases of SIH complicated by SDH. This revealed conflicting opinions concerning the management of this condition. CONCLUSIONS: Although blind lumbar EBP is often successful, targeted EBP has a lower rate of patients requiring a second EBP or other further treatment. On the other hand, targeted EBP has a larger risk profile. Depending on the clinic situation, treatment of the SDH via surgical evacuation may be necessary. PMID- 27693248 TI - Controlled lid-opening in Thermomyces lanuginosus lipase- An engineered switch for studying lipase function. AB - Here, we present a lipase mutant containing a biochemical switch allowing a controlled opening and closing of the lid independent of the environment. The closed form of the TlL mutant shows low binding to hydrophobic surfaces compared to the binding observed after activating the controlled switch inducing lid opening. We directly show that lipid binding of this mutant is connected to an open lid conformation demonstrating the impact of the exposed amino acid residues and their participation in binding at the water-lipid interface. The switch was created by introducing two cysteine residues into the protein backbone at sites 86 and 255. The crystal structure of the mutant shows the successful formation of a disulfide bond between C86 and C255 which causes strained closure of the lid domain. Control of enzymatic activity and binding was demonstrated on substrate emulsions and natural lipid layers. The locked form displayed low enzymatic activity (~10%) compared to wild-type. Upon release of the lock, enzymatic activity was fully restored. Only 10% binding to natural lipid substrates was observed for the locked lipase compared to wild-type, but binding was restored upon adding reducing agent. QCM-D measurements revealed a seven-fold increase in binding rate for the unlocked lipase. The TlL_locked mutant shows structural changes across the protein important for understanding the mechanism of lid opening and closing. Our experimental results reveal sites of interest for future mutagenesis studies aimed at altering the activation mechanism of TlL and create perspectives for generating tunable lipases that activate under controlled conditions. PMID- 27693246 TI - Permeability Surface Area Product Using Perfusion Computed Tomography Is a Valuable Prognostic Factor in Glioblastomas Treated with Radiotherapy Plus Concomitant and Adjuvant Temozolomide. AB - OBJECTIVE: The current standard treatment protocol for patients with newly diagnosed glioblastoma (GBM) includes surgery, radiotherapy, and concomitant and adjuvant temozolomide (TMZ). We hypothesized that the permeability surface area product (PS) from a perfusion computed tomography (PCT) study is associated with sensitivity to TMZ. The aim of this study was to determine whether PS values were correlated with prognosis of GBM patients who received the standard treatment protocol. METHODS: This study included 36 patients with GBM that were newly diagnosed between October 2005 and September 2014 and who underwent preoperative PCT study and the standard treatment protocol. We measured the maximum value of relative cerebral blood volume (rCBVmax) and the maximum PS value (PSmax). We statistically examined the relationship between PSmax and prognosis using survival analysis, including other clinicopathologic factors (age, Karnofsky performance status [KPS], extent of resection, O6-methylguanine-DNA methyltransferase [MGMT] status, second-line use of bevacizumab, and rCBVmax). RESULTS: Log-rank tests revealed that age, KPS, MGMT status, and PSmax were significantly correlated with overall survival. Multivariate analysis using the Cox regression model showed that PSmax was the most significant prognostic factor. Receiver operating characteristic curve analysis showed that PSmax had the highest accuracy in differentiating longtime survivors (LTSs) (surviving more than 2 years) from non-LTSs. At a cutoff point of 8.26 mL/100 g/min, sensitivity and specificity were 90% and 70%, respectively. CONCLUSIONS: PSmax from PCT study can help predict survival time in patients with GBM receiving the standard treatment protocol. Survival may be related to sensitivity to TMZ. PMID- 27693249 TI - Exposure of cultured fibroblasts to the peptide PR-11 for the identification of induced proteome alterations and discovery of novel potential ligands. AB - The PR-11 peptide corresponds to the N-terminal and active region of the endogenously synthesized PR-39 molecule, of porcine origin. It is known to possess various biological effects including antimicrobial properties, angiogenic and anti-inflammatory activities. Apart from its reported activity as a proteasome inhibitor, a more comprehensive understanding of its function, at the molecular level, is still lacking. In this study, we used a label-free shotgun strategy to evaluate the proteomic alterations caused by exposure of cultured fibroblasts to the peptide PR-11. This approach revealed that more than half of the identified molecules were related to signalling, transcription and translation. Proteins directly associated to regulation of angiogenesis and interaction with the hypoxia-inducible factor 1-alpha (HIF-1alpha) were significantly altered. In addition, at least three differentially expressed molecules of the NF-kappaB pathway were detected, suggesting an anti-inflammatory property of PR-11. At last, we demonstrated novel potential ligands of PR-11, through its immobilization for affinity chromatography. Among the eluted molecules, gC1qR, a known complement receptor, appeared markedly enriched. This provided preliminary evidence of a PR-11 ligand possibly involved in the internalization of this peptide. Altogether, our findings contributed to a better understanding of the cellular pathways affected by PR-39 derived molecules. PMID- 27693250 TI - A cobalt-containing eukaryotic nitrile hydratase. AB - Nitrile hydratase (NHase), an industrially important enzyme that catalyzes the hydration of nitriles to their corresponding amides, has only been characterized from prokaryotic microbes. The putative NHase from the eukaryotic unicellular choanoflagellate organism Monosiga brevicollis (MbNHase) was heterologously expressed in Escherichia coli. The resulting enzyme expressed as a single polypeptide with fused alpha- and beta-subunits linked by a seventeen-histidine region. Size-exclusion chromatography indicated that MbNHase exists primarily as an (alphabeta)2 homodimer in solution, analogous to the alpha2beta2 homotetramer architecture observed for prokaryotic NHases. The NHase enzyme contained its full complement of Co(III) and was fully functional without the co-expression of an activator protein or E. coli GroES/EL molecular chaperones. The homology model of MbNHase was developed identifying Cys400, Cys403, and Cys405 as active site ligands. The results presented here provide the first experimental data for a mature and active eukaryotic NHase with fused subunits. Since this new member of the NHase family is expressed from a single gene without the requirement of an activator protein, it represents an alternative biocatalyst for industrial syntheses of important amide compounds. PMID- 27693251 TI - Inhibition of CDK7 bypasses spindle assembly checkpoint via premature cyclin B degradation during oocyte meiosis. AB - To ensure accurate chromosome segregation, the spindle assembly checkpoint (SAC) delays anaphase onset by preventing the premature activation of anaphase promoting complex/cyclosome (APC/C) until all kinetochores are attached to the spindle. Although an escape from mitosis in the presence of unsatisfied SAC has been shown in several cancer cells, it has not been reported in oocyte meiosis. Here, we show that CDK7 activity is required to prevent a bypass of SAC during meiosis I in mouse oocytes. Inhibition of CDK7 using THZ1 accelerated the first meiosis, leading to chromosome misalignment, lag of chromosomes during chromosome segregation, and a high incidence of aneuploidy. Notably, this acceleration occurred in the presence of SAC proteins including Mad2 and Bub3 at the kinetochores. However, inhibition of APC/C-mediated cyclin B degradation blocked the THZ1-induced premature polar body extrusion. Moreover, chromosomal defects mediated by THZ1 were rescued when anaphase onset was delayed. Collectively, our results show that CDK7 activity is required to prevent premature anaphase onset by suppressing the bypass of SAC, thus ensuring chromosome alignment and proper segregation. These findings reveal new roles of CDK7 in the regulation of meiosis in mammalian oocytes. PMID- 27693253 TI - BMP4 promotes a phenotype change of an esophageal squamous epithelium via up regulation of KLF4. AB - INTRODUCTION: Barrett's esophagus is a metaplastic lesion. However, the cellular and molecular mechanisms involved are poorly understood. The aim of this study was to investigate the roles of KLF4 and BMP4 in the pathogenesis of Barrett's epithelium. MATERIALS AND METHODS: Immunohistochemistry was used to analyse the expression of KLF4, BMP4, CDX2, MUC2 and MUC5AC in human esophageal specimens. Human esophageal squamous epithelial cells were subjected to bile acid treatment and used in transfection experiments. Quantitative real-time PCR and Western blot analysis were used to detect the expression of KLF4, BMP4, CDX2, MUC2 and MUC5ac. RESULTS: In human tissues, Barrett's epithelium strongly expressed BMP4, p Smad1/5/8 and KLF4. Furthermore, bile acids increased the expression of BMP4, KLF4, p-Smad1/5/8, CDX2, MUC2 and MUC5ac in esophageal epithelial cells in a time dependent manner. Moreover, we found that BMP4 up-regulated the expression of KLF4, CDX2, MUC2 and MUC5ac, but Noggin, a specific BMP4 antagonist, can block the expression of KLF4, CDX2, MUC2 and MUC5ac induced by BMP4. However, BMP4 cannot induce the expression of CDX2, MUC2 and MUC5ac in cells with KLF4 siRNA, and Noggin cannot block the expression of KLF4, CDX2, MUC2 and MUC5ac in cells transfected with the KLF4 expression vector. CONCLUSION: Our results demonstrate that BMP4 promotes a phenotype change of an esophageal squamous epithelium via up regulation of KLF4. PMID- 27693254 TI - Hunger-Driven Motivational State Competition. AB - Behavioral choice is ubiquitous in the animal kingdom and is central to goal oriented behavior. Hypothalamic Agouti-related peptide (AgRP) neurons are critical regulators of appetite. Hungry animals, bombarded by multiple sensory stimuli, are known to modify their behavior during times of caloric need, rapidly adapting to a consistently changing environment. Utilizing ARCAgRP neurons as an entry point, we analyzed the hierarchical position of hunger related to rival drive states. Employing a battery of behavioral assays, we found that hunger significantly increases its capacity to suppress competing motivational systems, such as thirst, anxiety-related behavior, innate fear, and social interactions, often only when food is accessible. Furthermore, real-time monitoring of ARCAgRP activity revealed time-locked responses to conspecific investigation in addition to food presentation, further establishing that, even at the level of ARCAgRP neurons, choices are remarkably flexible computations, integrating internal state, external factors, and anticipated yield. VIDEO ABSTRACT. PMID- 27693255 TI - Molecular and Neural Functions of Rai1, the Causal Gene for Smith-Magenis Syndrome. AB - Haploinsufficiency of Retinoic Acid Induced 1 (RAI1) causes Smith-Magenis syndrome (SMS), which is associated with diverse neurodevelopmental and behavioral symptoms as well as obesity. RAI1 encodes a nuclear protein but little is known about its molecular function or the cell types responsible for SMS symptoms. Using genetically engineered mice, we found that Rai1 preferentially occupies DNA regions near active promoters and promotes the expression of a group of genes involved in circuit assembly and neuronal communication. Behavioral analyses demonstrated that pan-neural loss of Rai1 causes deficits in motor function, learning, and food intake. These SMS-like phenotypes are produced by loss of Rai1 function in distinct neuronal types: Rai1 loss in inhibitory neurons or subcortical glutamatergic neurons causes learning deficits, while Rai1 loss in Sim1+ or SF1+ cells causes obesity. By integrating molecular and organismal analyses, our study suggests potential therapeutic avenues for a complex neurodevelopmental disorder. PMID- 27693257 TI - Reallocation of Olfactory Cajal-Retzius Cells Shapes Neocortex Architecture. AB - The neocortex undergoes extensive developmental growth, but how its architecture adapts to expansion remains largely unknown. Here, we investigated how early born Cajal-Retzius (CR) neurons, which regulate the assembly of cortical circuits, maintain a dense superficial distribution in the growing neocortex. We found that CR cell density is sustained by an activity-dependent importation of olfactory CR cells, which migrate into the neocortex after they have acted as axonal guidepost cells in the olfactory system. Furthermore, using mouse genetics, we showed that CR cell density severely affects the architecture of layer 1, a key site of input integration for neocortical networks, leading to an excitation/inhibition ratio imbalance. Our study reveals that neurons reenter migration several days after their initial positioning, thereby performing sequential developmental roles in olfactory cortex and neocortex. This atypical process is essential to regulate CR cell density during growth, which in turn ensures the correct wiring of neocortical circuitry. VIDEO ABSTRACT. PMID- 27693252 TI - TDP-43/FUS in motor neuron disease: Complexity and challenges. AB - Amyotrophic lateral sclerosis (ALS), a common motor neuron disease affecting two per 100,000 people worldwide, encompasses at least five distinct pathological subtypes, including, ALS-SOD1, ALS-C9orf72, ALS-TDP-43, ALS-FUS and Guam-ALS. The etiology of a major subset of ALS involves toxicity of the TAR DNA-binding protein-43 (TDP-43). A second RNA/DNA binding protein, fused in sarcoma/translocated in liposarcoma (FUS/TLS) has been subsequently associated with about 1% of ALS patients. While mutations in TDP-43 and FUS have been linked to ALS, the key contributing molecular mechanism(s) leading to cell death are still unclear. One unique feature of TDP-43 and FUS pathogenesis in ALS is their nuclear clearance and simultaneous cytoplasmic aggregation in affected motor neurons. Since the discoveries in the last decade implicating TDP-43 and FUS toxicity in ALS, a majority of studies have focused on their cytoplasmic aggregation and disruption of their RNA-binding functions. However, TDP-43 and FUS also bind to DNA, although the significance of their DNA binding in disease affected neurons has been less investigated. A recent observation of accumulated genomic damage in TDP-43 and FUS-linked ALS and association of FUS with neuronal DNA damage repair pathways indicate a possible role of deregulated DNA binding function of TDP-43 and FUS in ALS. In this review, we discuss the different ALS disease subtypes, crosstalk of etiopathologies in disease progression, available animal models and their limitations, and recent advances in understanding the specific involvement of RNA/DNA binding proteins, TDP-43 and FUS, in motor neuron diseases. PMID- 27693256 TI - The Dynamics of Functional Brain Networks: Integrated Network States during Cognitive Task Performance. AB - Higher brain function relies upon the ability to flexibly integrate information across specialized communities of brain regions; however, it is unclear how this mechanism manifests over time. In this study, we used time-resolved network analysis of fMRI data to demonstrate that the human brain traverses between functional states that maximize either segregation into tight-knit communities or integration across otherwise disparate neural regions. Integrated states enable faster and more accurate performance on a cognitive task, and are associated with dilations in pupil diameter, suggesting that ascending neuromodulatory systems may govern the transition between these alternative modes of brain function. Together, our results confirm a direct link between cognitive performance and the dynamic reorganization of the network structure of the brain. PMID- 27693258 TI - Clustering and Functional Coupling of Diverse Ion Channels and Signaling Proteins Revealed by Super-resolution STORM Microscopy in Neurons. AB - The fidelity of neuronal signaling requires organization of signaling molecules into macromolecular complexes, whose components are in intimate proximity. The intrinsic diffraction limit of light makes visualization of individual signaling complexes using visible light extremely difficult. However, using super resolution stochastic optical reconstruction microscopy (STORM), we observed intimate association of individual molecules within signaling complexes containing ion channels (M-type K+, L-type Ca2+, or TRPV1 channels) and G protein coupled receptors coupled by the scaffolding protein A-kinase-anchoring protein (AKAP)79/150. Some channels assembled as multi-channel supercomplexes. Surprisingly, we identified novel layers of interplay within macromolecular complexes containing diverse channel types at the single-complex level in sensory neurons, dependent on AKAP79/150. Electrophysiological studies revealed that such ion channels are functionally coupled as well. Our findings illustrate the novel role of AKAP79/150 as a molecular coupler of different channels that conveys crosstalk between channel activities within single microdomains in tuning the physiological response of neurons. PMID- 27693259 TI - From healthcare to health: A proposed pathway to population health. AB - Innovations in payment are encouraging clinical-community partnerships that address health determinants. However, little is known about how healthcare systems transform and partner to improve population health. We synthesized views of population health experts from nine organizations and illustrated the resulting model using examples from four health systems. The transformation requires a foundation of primary care, connectors and integrators that span the boundaries, sharing of goals among participants, aligned funding and incentives, and a supporting infrastructure, all leading to a virtuous cycle of collaboration. Policies are needed that will provide funding and incentives to encourage spread beyond early adopter organizations. PMID- 27693260 TI - A Dynamic Predictive Model for Progression of CKD. AB - BACKGROUND: Predicting the progression of chronic kidney disease (CKD) is vital for clinical decision making and patient-provider communication. We previously developed an accurate static prediction model that used single-timepoint measurements of demographic and laboratory variables. STUDY DESIGN: Development of a dynamic predictive model using demographic, clinical, and time-dependent laboratory data from a cohort of patients with CKD stages 3 to 5. SETTING & PARTICIPANTS: We studied 3,004 patients seen April 1, 2001, to December 31, 2009, in the outpatient CKD clinic of Sunnybrook Hospital in Toronto, Canada. CANDIDATE PREDICTORS: Age, sex, and urinary albumin-creatinine ratio at baseline. Estimated glomerular filtration rate (eGFR), serum albumin, phosphorus, calcium, and bicarbonate values as time-dependent predictors. OUTCOMES: Treated kidney failure, defined by initiation of dialysis therapy or kidney transplantation. ANALYTICAL APPROACH: We describe a dynamic (latest-available-measurement) prediction model using time-dependent laboratory values as predictors of outcome. Our static model included all 8 candidate predictors. The latest-available measurement model includes age and the latter 5 variables as time-dependent predictors. We used Cox proportional hazards models for time to kidney failure and compared discrimination, calibration, model fit, and net reclassification for the models. RESULTS: We studied 3,004 patients, who had 344 kidney failure events over a median follow-up of 3 years and an average of 5 clinic visits. eGFR was more strongly associated with kidney failure in the latest-available-measurement model versus the baseline visit static model (HR, 0.44 vs 0.65). The association of calcium level was unchanged, but male sex and phosphorus, albumin, and bicarbonate levels were no longer significant. Discrimination and goodness of fit showed incremental improvement with inclusion of time-dependent covariates (integrated discrimination improvement, 0.73%; 95% CI, 0.56%-0.90%). LIMITATIONS: Our data were derived from a nephrology clinic at a single center. We were unable to include time-dependent changes in albuminuria. CONCLUSIONS: A latest-available measurement predictive model with eGFR as a time-dependent predictor can incrementally improve risk prediction for kidney failure over a static model with only a single eGFR. PMID- 27693262 TI - Trends in Receipt of Intensive Procedures at the End of Life Among Patients Treated With Maintenance Dialysis. AB - BACKGROUND: Many dialysis patients receive intensive procedures intended to prolong life at the very end of life. However, little is known about trends over time in the use of these procedures. We describe temporal trends in receipt of inpatient intensive procedures during the last 6 months of life among patients treated with maintenance dialysis. STUDY DESIGN: Mortality follow-back study. SETTING & PARTICIPANTS: 649,607 adult Medicare beneficiaries on maintenance dialysis therapy who died in 2000 to 2012. PREDICTORS: Period of death (2000 2003, 2004-2008, or 2009-2012), age at time of death (18-59, 60-64, 65-69, 70-74, 75-79, 80-84, and >=85 years), and race/ethnicity (Hispanic, non-Hispanic black, or non-Hispanic white). OUTCOME: Receipt of an inpatient intensive procedure (defined as invasive mechanical ventilation/intubation, tracheostomy, gastrostomy/jejunostomy tube insertion, enteral or parenteral nutrition, or cardiopulmonary resuscitation) during the last 6 months of life. RESULTS: Overall, 34% of cohort patients received an intensive procedure in the last 6 months of life, increasing from 29% in 2000 to 36% in 2012 (with 2000-2003 as the referent category; adjusted risk ratios [RRs] were 1.06 [95% CI, 1.05-1.07] and 1.10 [95% CI, 1.09-1.12] for 2004-2008 and 2009-2012, respectively). Use of intensive procedures increased more markedly over time in younger versus older patients (comparing 2009-2012 to 2000-2003, adjusted RR was 1.18 [95% CI, 1.15 1.20] for the youngest age group as opposed to 1.00 [95% CI, 0.96-1.04] for the oldest group). Comparing 2009 to 2012 to 2000 to 2003, the use of intensive procedures increased more dramatically for Hispanic patients than for non Hispanic black or non-Hispanic white patients (adjusted RRs of 1.18 [95% CI, 1.14 1.22], 1.09 [95% CI, 1.07-1.11], and 1.10 [95% CI, 1.08-1.12], respectively). LIMITATIONS: Data sources do not provide insight into reasons for observed trends in the use of intensive procedures. CONCLUSIONS: Among patients treated with maintenance dialysis, there is a trend toward more frequent use of intensive procedures at the end of life, especially in younger patients and those of Hispanic ethnicity. PMID- 27693263 TI - Psychosexual Outcome Among Iranian Individuals With 5alpha-Reductase Deficiency Type 2 and Its Relationship With Parental Sexism. AB - INTRODUCTION: Few studies exist on the psychosexual outcome of homogeneous groups of individuals with 5alpha-reductase deficiency type 2 (5alpha-RD-2) and the relation between gender changes and parental hostile and benevolent sexism, which are two components of ambivalent sexism that assume a stereotypical approach toward women in an overtly negative way or a chivalrous, seemingly positive way. AIM: To report on the psychosexual outcome of individuals with 5alpha-RD-2 and to investigate its relation to the level of parental sexism in a relatively large sample of Iranians with 5alpha-RD-2. METHODS: Twenty participants (mean age = 19.5 years, SD = 6.345) with a molecularly confirmed diagnosis of 5alpha-RD-2 who were assigned the female gender at birth and raised as female were included in the study. Participants and their parents were interviewed and their medical records were assessed. Parents also completed the Ambivalent Sexism Inventory (ASI), which includes hostile and benevolent sexism subscales. MAIN OUTCOME MEASURES: Psychosexual outcome and parental hostile and benevolent sexism measurements. RESULTS: Twelve of 20 participants (60%) were diagnosed with gender identity disorder not otherwise specified (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision). Ten of these transitioned to the male gender. The other 10 participants (50%), including the two diagnosed with gender identity disorder not otherwise specified, continued living in a female gender role. When comparing the ASI subscale scores between families of participants who changed their gender and those who did not, no significant difference was found for ASI total and hostile sexism scores, but there was a difference for benevolent sexism (P = .049): those whose daughters had changed their gender had higher benevolent sexism scores. CONCLUSION: The high prevalence of gender change and gender dysphoria reported in the literature was confirmed in this relatively large and homogeneous sample of Iranians with 5-alpha-RD-2 raised as female. Prenatal exposure to testosterone is hypothesized to play a role in the development of gender identity and sexual orientation, but parental attitudes also might be important. Although gender change in individuals with 5-alpha-RD-2 is often attributed to high levels of hostile sexism in some cultures, our findings show this to be associated with benevolent sexism.

AB - Maintenance dialysis patients experience a high burden of physical and emotional symptoms that directly affect their quality of life and health care utilization. In this review, we specifically highlight common troublesome symptoms affecting dialysis patients: insomnia, restless legs syndrome, and uremic pruritus. Epidemiology, pathophysiology, and evidence-based current treatment are reviewed with the goal of providing a guide for diagnosis and treatment. Finally, we identify multiple additional areas of further study needed to improve symptom management in dialysis patients. PMID- 27693264 TI - Surgical Outcomes of Erectile Implants After Phalloplasty: Retrospective Analysis of 95 Procedures. AB - INTRODUCTION: The creation of a neophallus is a complex surgery that must meet functional and esthetic requirements. It is a long and demanding surgical process whose final stage consists of the implantation of a rigid or inflatable material that can be used to reproduce an erection. Data in the literature are scarce, with only the pioneering series present, which includes the use of the first devices and techniques. AIM: To report the outcome of patients with phalloplasty after implantation of erectile implants using standardized surgical techniques and the use of recent prosthesis types with or without a vascular graft. METHODS: This is a retrospective hospital-based analysis of all patients with phalloplasty who underwent implantation of an erectile prosthesis from March 2007 to May 2015. Factors associated with complications were investigated by multivariate logistic regression analysis. MAIN OUTCOME MEASURES: Early-onset (during the first month after surgery) and late-onset complications, including erosion, infections, malpositioning, and dysfunction. RESULTS: Sixty-nine patients were included in the study and 95 procedures were analyzed. After a median follow-up of 4 years (minimum = 169 days, maximum = 6.1 years), the original prosthesis was still in place in 43 patients (62.3%). Patients underwent phalloplasty after female-to male transsexualism (n = 62, 89.9%), malformation (n = 4, 5.8%), or trauma (n = 3, 4.3%). The proportions for the different types of phalloplasty were 58% for forearm free flap phalloplasty (n = 40), 33.3% for suprapubic phalloplasty (n = 23), and 7% for other (n = 6). The erectile prostheses used were the two-piece AMS Ambicor (n = 71, 74.7%), the Ambicor with a vascular graft (n = 19, 20.0%), and the AMS 700CXR, AMS 700CX, or AMS600-650 (n = 5, 5.2%). There were no early onset complications in 89 procedures (93.7%) and, when present, they were always related to infection (n = 4, 4.2%). Late-onset complications were erosion (n = 4, 4.2%), infection (n = 4, 4.2%), dysfunction (n = 10, 10.5%), and malpositioning (n = 12, 12.6%). No significant difference was observed for malpositioning (12.7% vs 10.5%, P = .87) and dysfunction (7.0% vs 10.5%, P = .78) between the AMS Ambicor prosthesis and the Ambicor prosthesis with a vascular graft. CONCLUSION: This study provides updated data on complications after the implantation of erectile implants. Multicenter studies, including the evaluation of patient satisfaction, are needed to increase our understanding of factors associated with the outcomes. PMID- 27693265 TI - Differential Effects of Cyproterone Acetate vs Spironolactone on Serum High Density Lipoprotein and Prolactin Concentrations in the Hormonal Treatment of Transgender Women. AB - INTRODUCTION: Spironolactone and cyproterone acetate (CPA) are the two main antiandrogen medications used in feminizing hormone therapy in transgender women. Previous studies have suggested that these two agents might have opposite effects on high-density lipoprotein (HDL) level when used in this context, and limited data have suggested CPA increases prolactin more than spironolactone. AIM: To compare the effects of spironolactone and CPA on HDL and prolactin serum concentrations in transgender women. METHODS: A retrospective chart review was conducted at three clinical sites in Toronto, Ontario, Canada. Patients were selected if they (i) identified as a transgender woman, (ii) had newly started spironolactone or CPA with estrogen or restarted spironolactone or CPA after a washout period of at least 6 months, and (iii) had not used other antiandrogens within the previous 6 months. MAIN OUTCOME MEASURES: HDL and prolactin concentrations between the two treatment groups at baseline and at 12 months. RESULTS: Eighty-two patients were included in the spironolactone group and 31 patients were included in the CPA group. Baseline HDL and prolactin levels were not significantly different between the two groups. At 12 months, HDL increased by 0.10 mmol/L (SD = 0.24) in the spironolactone group but decreased by 0.07 mmol/L (SD = 0.21) in the CPA group (P = .002). The difference remained significant after adjusting for baseline HDL, use of lipid-lowering drugs, and age. The change in prolactin was +3.10 MUg/L (SD = 5.70) in the spironolactone group and +11.8 MUg/L (SD = 8.63) in the CPA group (P < 0.001). This difference also remained significant after adjusting for baseline prolactin level. CONCLUSION: These data suggest that spironolactone use in transgender women increases HDL levels and that CPA has the opposite effect. CPA also is associated with a larger increase in prolactin. These factors should be considered when choosing between these two antiandrogen agents. PMID- 27693266 TI - Imipramine ameliorates early life stress-induced alterations in synaptic plasticity in the rat lateral amygdala. AB - Long-term potentiation (LTP) and long-term depression (LTD) are two opposite forms of synaptic plasticity at the cortical and thalamic inputs to the lateral amygdala (LA). It has been demonstrated that maternal separation (MS) of rat pups results in alterations in the potential for both pathways to undergo LTP and LTD in adolescence. Imipramine, a prototypic tricyclic antidepressant, has been shown to counteract some detrimental effects of MS on rat behavior, however it is not known whether MS-induced alterations in the potential for bidirectional synaptic plasticity in the LA could be reversed by imipramine treatment. To this end, rat pups were subjected to MS (3h/day) on postnatal days (PNDs) 1-21. On each of PNDs 29-42, male rats previously subjected to MS were injected subcutaneously with imipramine (10mg/kg). Field potentials were recorded ex vivo from slices containing the LA and saturating levels of LTP and LTD were induced. At the thalamic input to the LA, both the maximum LTP and the maximum LTD were reduced in rats subjected to MS when compared to control animals, confirming earlier results. However, these effects were no longer present in rats subjected to MS and later treated with imipramine. At the cortical input in slices prepared from MS-subjected rats, an impairment of the maximum LTP and an enhancement of the maximum LTD were observed. At the cortical input in rats subjected to MS and receiving imipramine treatment, the level of LTD was comparable to control but imipramine did not restore the potential for LTP at this input. These results demonstrate that imipramine fully reverses the effects of MS in the thalamo amygdalar pathway, however, in the cortico-amygdalar pathway the reversal of the effects of MS by imipramine is partial.

PMID- 27693268 TI - ORF7 from Amycolatopsis orientalis catalyzes decarboxylation of Ndelta methylarginine and amine oxidation of arginine: Biosynthetic implications. AB - A key step in the biosynthesis of the polyene polyketide ECO-0501 by Amycolatopsis orientalis ATCC 43491 is thought to involve oxidative decarboxylation of arginine or Ndelta-methylarginine to the corresponding primary amide. This reaction is the centerpiece of a recently identified biosynthetic cassette that generates 4-guanidinobutyryl thioesters to serve as starter units for polyketide synthesis. We examined the reaction of ORF7, the predicted ECO 0501 biosynthetic decarboxylase, with arginine, and saw no evidence of decarboxylation. Instead, we observed exclusive amine oxidation to generate 2 oxoarginine, with a kcat/KM,Arg of 5.6*106M-1s-1, typical of values measured for physiological amino acid decarboxylases. In contrast, when ORF7 was incubated with Ndelta-methylarginine, we observed exclusive decarboxylation to generate 4 (N1-methylguanidino)butyramide. These differing reactive pathways provide insight into the biosyntheses of guanidinobutyryl-derived polyketides and demonstrate the biosynthetic versatility of arginine-processing decarboxylases. In addition, it suggests that ORF7 may be an incisive model system for dissecting the determinants of flavoprotein-catalyzed oxidase and monooxygenase modes of reactivity. PMID- 27693270 TI - Selection of recipient vessels for free flap following intra-arterial chemoradiotherapy. AB - OBJECTIVE: This study aims at selecting recipient vessels for free flap following intra-arterial chemoradiotherapy. At present, many centers combine intra-arterial chemotherapy and concomitant radiotherapy for treating head and neck cancer with favorable results. However, some patients develop recurrent, residual disease/complications after completing treatment protocols and thus require free flap surgery. The feasibility of microsurgery following intra-arterial chemoradiotherapy remains unclear. STUDY DESIGN AND METHODS: We retrospectively analyzed 730 patients who underwent free-flap surgery for managing treatment related complications/defects following head and neck surgery from January 1999 to February 2012. All patients were categorized into two groups according to the presence (group A)/absence (group B) of a history of intra-arterial chemotherapy. Microvascular revision rates were compared between the groups. In group A, the correlation between catheterization sites and recipient vessels used for microsurgery was assessed. RESULTS: A total of 769 free flaps were created in 730 patients and comprised 36 and 733 flaps in groups A and B, respectively. Microvascular revision rates were 2.8% (1/36) and 4.2% (31/733) in groups A and B, respectively, with no significant difference observed between the groups. No statistically significant difference was observed when only cases of arterial thrombosis were included. Vessels used for recipient anastomoses were not directly exposed to intra-arterially injected agents. CONCLUSION: Preoperative intra-arterial chemoradiotherapy does not significantly increase the risk of microvascular revisions, particularly artery-related revisions, if vessels selectively catheterized and perfused with chemotherapeutic agents during intra arterial chemotherapy are avoided as recipient vessels. PMID- 27693271 TI - An analysis of pose in 3D stereophotogrammetry of the breast. AB - BACKGROUND: Volume of the breast can be objectively measured by three-dimensional (3D) photographs. This study describes the analysis of three different positions of the patient in image acquisition, in order to find the best pose for reproducible 3D photographs of the breasts. METHOD: Twenty-four patients were included between February and September 2014 in a consecutive way. Data were collected prospectively. 3D photographs were acquired using a stereophotogrammetry system. Images were taken twice in three different positions (arms behind the back, arms placed on the hips and arms horizontally placed). Surface based matching was applied and the absolute mean distance between the surfaces of both 3D models of the same position was calculated. This difference measure represents the similarity of the photographs. RESULTS: Univariate ANOVA showed a significant difference in distance between the three positions (sum of squares 1.12, p < 0.001). The horizontal position presented the lowest absolute mean distance (0.45 mm). Additional post hoc multiple comparisons analysis revealed a statistically significant difference between the distances of horizontal and back position (-0.22 mm, p < 0.001) and of back and hip position (0.13 mm, p = 0.009), with better results of the horizontal and hip positions, respectively. CONCLUSION: Standardization of 3D acquisition in pre- and postoperative breast imaging could improve imaging reproducibility. Based on the results of this study, we recommend a pose with the arms in a horizontal position. PMID- 27693272 TI - Lymphoscintigraphy mapping of truncal malignant melanoma: A study of 212 patients at the Christie NHS Foundation Trust. AB - BACKGROUND AND PURPOSE: Malignant melanoma (MM) on the trunk, because of its anatomical location, has multiple potential lymphatic basins to which to drain. The aim of this study is to map the location of the sentinel lymph node (SLN) on the basis of the anatomical location of the primary malignant melanoma on the trunk. METHODS: Patients diagnosed with MM on the trunk who had undergone a SLN biopsy from January 2006 to March 2015 were identified in the Christie NHS Foundation Trust through a computer database search. The anterior and posterior surfaces of the trunk were divided into four sections each. RESULTS: A total of 212 patients were evaluated. MM was more common on the posterior trunk, accounting for 73% of cases, and 57% of melanomas were on the right side of the trunk. The axillary basins were involved in drainage in 91.5% of all truncal melanomas. Drainage was to a single lymphatic basin in 68.3% of cases. The incidence of drainage to multiple lymphatic basins was not uniform for the anterior and posterior surfaces of the trunks. CONCLUSION: One-third of MM on the posterior surface of the trunk will drain to multiple basins. Around 50% of the melanomas of the upper back drain to a contralateral basin. Independent of the location of the MM, the axillary basins were the most common location of drainage, with a total of 91% of the cohort. Therefore, the location of the SLN could be predicted, depending on the location of the MM on the trunk. PMID- 27693273 TI - Surgical anatomy of the first extensor compartment: A systematic review and comparison of normal cadavers vs. De Quervain syndrome patients. AB - PURPOSE: De Quervain syndrome or tenosynovitis is a common wrist pathology caused by stenosing tenosynovitis of the first dorsal compartment. Multiple studies have demonstrated significant anatomic variation within the first extensor compartment. METHODS: The terms "De Quervain's tenosynovitis" and "first extensor compartment anatomy" were comprehensively searched using the PubMed, MEDLINE, and Cochrane database. The presence of a septum within the first dorsal compartment, the number of APL (abductor pollicis longus), and EPB (extensor pollicis brevis) tendon slips were identified. RESULTS: A total of 574 articles were identified on initial search, of which 21 met inclusion criteria. There were 1901 normal cadaver specimens and 470 surgically treated De Quervain disease patients, whose data were available. A septum was present in 43.7% of normal cadavers versus 62.2% De Quervain patients with 58.5% (327 of 559) of the septi characterized as incomplete. There was a difference in the number of APL tendons with a single APL tendon slip noted in 18.3% of normal cadavers (200/1096) versus 27.2% of De Quervain patients (87/230). There was a difference in the number of EPB tendons between the normal cadavers and De Quervain's wrists with 2 or more EPB tendinous slips observed in 5.9% of normal cadavers compared with 2.9% of De Quervain patients. CONCLUSION: Significant anatomic variability exists within the first extensor compartment. Patients with De Quervain disease were more likely to have a septum dividing the compartment and a single slip of APL. These variations are clinically relevant in the pathophysiology and treatment of De Quervain's tenosynovitis. TYPE OF STUDY: Prognostic studies. LEVEL OF EVIDENCE: Level III. PMID- 27693274 TI - Anti Xa oral anticoagulants inhibit in vivo platelet activation by modulating glycoprotein VI shedding. AB - Anti Xa non-vitamin K oral anticoagulants (anti Xa NOACs) seem to possess antiplatelet effect in vitro, but it is unclear if this occurs also in vivo. Aim of the study was to compare the effect on platelet activation of two anti Xa NOACs, namely apixaban and rivaroxaban, to warfarin, and to investigate the potential underlying mechanism by evaluating soluble glycoprotein GPVI (sGPVI), a protein involved in platelet activation. We performed a cross-sectional including AF patients treated with warfarin (n=30), or apixaban 10mg/day (n=40), or rivaroxaban 20mg/day (n=40). Patients were balanced for sex, age and cardiovascular risk factors. Platelet activation by urinary excretion of 11 dehydro-thromboxane (Tx) B2 and soluble GPVI (sGPVI) were analysed at baseline and after 3 months of treatment. Baseline TxB2 value was 155.2+/-42.7ng/mg creatinine. The 3 months-variation of urinary excretion of TxB2 was -6.5% with warfarin (p=0.197), -29% with apixaban (p<0.001) and -31% with rivaroxaban (p<0.001). Use of anti Xa NOACs was independently associated to the variation of urinary TxB2 (B: -0.469, p<0.001), after adjustment for clinical characteristics; sGPVI was significantly lower in patients treated with NOACs at 3 months (p<0.001), while only a trend for the warfarin group (p=0.116) was observed. The variation of sGPVI was correlated with that of TxB2 in the NOACs group (Rs: 0.527, p<0.001). In 15 patients (5 per each group) platelet recruitment was significantly lowered at 3 months by NOACs (p<0.001), but not by warfarin. The study provides evidence that anti Xa NOACs significantly inhibit urinary TxB2 excretion compared to warfarin, suggesting that NOACs possess antiplatelet property.

PMID- 27693276 TI - Doxorubicin loaded gold nanoparticles: Implication of passive targeting on anticancer efficacy. AB - The present work aims to investigate targeting potential of doxorubicin (Dox) functionalized gold nanoparticles (D-GNPs) for treatment of chemically induced fibrosarcoma in mice. Carrier GNPs were synthesised by green chemistry method and loaded with doxorubicin by incubation method. D-GNPs were studied for its biocompatibility using normal mouse fibroblasts (L929) and found to be cell compatible and non-toxic. D-GNPs (at a dose of 2.5, 2 and 1.5mg/kg equivalent to Dox) demonstrated passive targeting measured as function of antitumor efficacy against chemical induced fibrosarcoma which showed higher latency to the tumour growth as compared to free Dox (2.5mg/kg). D-GNPs exhibited significantly higher therapeutic anticancer efficacy (~81% tumour suppression at dose of 2.5mg/kg equivalent to Dox) in the same model as compared to that of free doxorubicin (~48% tumour suppression at dose of 2.5mg/kg). Safety profile and targeting efficiency of developed formulation was established by assessing cardiac and blood markers. PMID- 27693278 TI - [Pediatric kidney transplantation]. AB - AIMS: To describe indications, surgical aspects, results and outcomes of kidney transplantation in children. MATERIAL AND METHODS: An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords (MESH): "kidney transplantation", "pediatric", "children", "outcomes". Publications obtained were selected based on methodology, language, date of publication (last 10 years) and relevance. Prospective and retrospective studies, in English or French, review articles; meta-analysis and guidelines were selected and analyzed. This search found 2608 articles. After reading titles and abstracts, 18 were included in the text based on their relevance. RESULTS: Kidney transplantation is the gold-standard treatment for end stage renal kidney disease in children. The surgical procedure is well standardized with a retroperitoneal approach when child and kidney size allow it or a transperitoneal approach in child less than 15 kg and big size kidney graft. Anastomosis sites include iliac vessels in the retroperitoneal approach, and inferior vena cava and aorta in case of transperitoneal procedure. Ureteral reimplantation used most of the time a Campos Freire technique. Sometimes, particular conditions in the recipient (such as vena cava thrombosis) required procedure adaptation. CONCLUSION: Graft survival dramatically increased over the past few years and is now superior to those observed in adult kidney transplantation, particularly in experienced team with microsurgery skills. Immunosuppressive treatments are similar to adults. Viral infections and post transplant lymphoproliferative disorder are the main complications of renal transplantation in children and may lead to lethal outcomes. An increase graft loss is observed during boyhood due to immunosuppressive drugs uncompliance. PMID- 27693279 TI - [Ischemia-reperfusion. Preservation solution and hypothermic machine perfusion]. AB - AIMS: To describe ischemia-reperfusion mechanisms, the impact on kidney graft and strategies developed to minimize ischemia-reperfusion damages. MATERIAL AND METHODS: An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords: ischemia-reperfusion; organ preservation; hypothermic machine perfusion; renal transplantation. Publications obtained were selected based on methodology, language, date of publication and relevance. Prospective and retrospective studies, in English or French, review articles; meta-analysis and guidelines were selected and analyzed. This search found 1293 articles. After reading titles and abstracts, 88 were included in the text, based on their relevance. RESULTS: Ischemia-reperfusion injuries occur when blood supply of an organ is interrupted or drastically reduced. Ischemic damages started immediately after arterial clamping in donor, persist during cold ischemia time, and are increased after reperfusion because of increased oxygen levels, organ warming and recipient cell infiltration. Besides metabolic and biologic impact, IR induced dramatic immunologic impact through immunologic cells activation. CONCLUSIONS: Knowledge of IR mechanisms is crucial to improve organ storage strategies and to decreased impact of IR on long-term graft and patient survival. Hypothermic machine perfusion was associated with prolonged graft survival versus cold storage. Principles and results of hypothermic machine perfusion will be reported. PMID- 27693280 TI - Emergency department point-of-care ultrasound in out-of-hospital and in-ED cardiac arrest. AB - BACKGROUND: Point-of-care ultrasound has been suggested to improve outcomes from advanced cardiac life support (ACLS), but no large studies have explored how it should be incorporated into ACLS. Our aim was to determine whether cardiac activity on ultrasound during ACLS is associated with improved survival. METHODS: We conducted a non-randomized, prospective, protocol-driven observational study at 20 hospitals across United States and Canada. Patients presenting with out-of hospital arrest or in-ED arrest with pulseless electrical activity or asystole were included. An ultrasound was performed at the beginning and end of ACLS. The primary outcome was survival to hospital admission. Secondary outcomes included survival to hospital discharge and return of spontaneous circulation. FINDINGS: 793 patients were enrolled, 208 (26.2%) survived the initial resuscitation, 114 (14.4%) survived to hospital admission, and 13 (1.6%) survived to hospital discharge. Cardiac activity on US was the variable most associated with survival at all time points. On multivariate regression modeling, cardiac activity was associated with increased survival to hospital admission (OR 3.6, 2.2-5.9) and hospital discharge (OR 5.7, 1.5-21.9). No cardiac activity on US was associated with non-survival, but 0.6% (95% CI 0.3-2.3) survived to discharge. Ultrasound identified findings that responded to non-ACLS interventions. Patients with pericardial effusion and pericardiocentesis demonstrated higher survival rates (15.4%) compared to all others (1.3%). CONCLUSION: Cardiac activity on ultrasound was the variable most associated with survival following cardiac arrest. Ultrasound during cardiac arrest identifies interventions outside of the standard ACLS algorithm. PMID- 27693284 TI - Reply by Authors. PMID- 27693281 TI - Self-assessment of social cognitive ability in individuals with schizophrenia: Appraising task difficulty and allocation of effort. AB - Patients with severe mental illnesses manifest substantial deficits in self assessment of the abilities that impact everyday functioning. This study compares patients with schizophrenia to healthy individuals on their social cognitive performance, their assessment of that performance, and the convergence between performance and indicators of effort in solving tasks. Patients with schizophrenia (n=57) and healthy controls (HC; n=47) completed the Bell-Lysaker Emotion Recognition Test (BLERT), a psychometrically sound assessment of emotion recognition. Participants rated their confidence in the accuracy of their responses after each item. Participants were instructed to respond as rapidly as possible without sacrificing accuracy; the time to complete each item was recorded. Patients with schizophrenia performed less accurately on the BLERT than HC. Both patients and HC were more confident on items that they correctly answered than for items with errors, with patients being less confident overall; there was no significant interaction for confidence between group and accuracy. HC demonstrated a more substantial adjustment of response time to task difficulty by taking considerably longer to solve items that they got wrong, whereas patients showed only a minimal adjustment. These results expand knowledge about both self-assessment of social cognitive performance and the ability to appraise difficulty and adjust effort to social cognitive task demands in patients with schizophrenia. PMID- 27693282 TI - Pattern of activation during delayed matching to sample task predicts functional outcome in people at ultra high risk for psychosis. AB - BACKGROUND: Clinical outcomes in people identified as at ultra-high risk (UHR) for psychosis are remarkably heterogeneous, and are difficult to predict on the basis of the presenting clinical features. Individuals at UHR are at risk of poor functional outcome regardless of development of psychotic disorder. The aim of the present study was to assess whether there is a relationship between functional neuroimaging measures at presentation and functional outcome as measured by the GAF three years after scanning. METHODS: Functional magnetic resonance imaging (fMRI) data were collected during an object working memory task in 34 ultra-high risk (UHR) subjects and 20 healthy controls. On the basis of their GAF scores at follow up, the UHR participants were divided into subgroups with good and poor functional outcomes, respectively. RESULTS: At baseline, the UHR group differed from controls in showing altered frontal and cuneus/posterior cingulate activation. Significant group x task interactions were found in the left cuneus and posterior cingulate gyrus, reflecting differential responses to the task conditions. Within the UHR sample, the subgroup with a poor functional outcome exhibited altered activation in frontal, temporal and striatal regions, and reduced deactivation within default-mode network regions, relative to those with a good outcome. Within the whole UHR sample, in these regions the local task response was correlated with the GAF score at follow up. CONCLUSIONS: The findings suggest a potential role of functional neuroimaging in the prediction of outcomes in people at high clinical risk of psychosis.

PMID- 27693288 TI - Implementation of a Comprehensive Post-Discharge Venous Thromboembolism Prophylaxis Program for Abdominal and Pelvic Surgery Patients. AB - BACKGROUND: Prophylactic anticoagulation is routinely used in the inpatient setting; however, the risk of venous thromboembolism (VTE) remains elevated after discharge. Extensive evidence and clinical guidelines suggest post-discharge VTE prophylaxis is critical in at-risk populations, but it remains severely underused in practice. STUDY DESIGN: We performed a single-institution retrospective, nonrandomized, pre- and post-intervention analysis of a systematic post-discharge pharmacologic prophylaxis program against the primary end point, which is post discharge symptomatic VTE. An institutional American College of Surgeons NSQIP dataset was used to identify patients and outcomes. Patients undergoing major abdominal surgery for malignancy or inflammatory bowel disease were eligible for the post-discharge VTE prevention program. RESULTS: Among 1,043 patients who underwent abdominal surgery for malignancy or inflammatory bowel disease, 800 (77%) were in the pre-intervention cohort and 243 (23%) patients were in the post intervention cohort. Rates of inpatient VTE did not significantly differ between cohorts (0.7%, n = 6 pre-intervention vs 1.7%, n = 4 post-intervention; p = 0.25). However, compared with the pre-intervention cohort, patients in the post intervention cohort demonstrated a significantly lower post-discharge VTE rate (2.5%, n = 20 pre-intervention vs 0.0%, n = 0 post-intervention; p < 0.01). CONCLUSIONS: A systematic post-discharge VTE prophylaxis program including provider education, local guideline adaptation, bedside medication delivery, and education for at-risk patients, was associated with significantly fewer post discharge VTE events. PMID- 27693289 TI - Temporal dynamics of 'HoBi'-like pestivirus quasispecies in persistently infected calves generated under experimental conditions. AB - 'HoBi'-like virus is an atypical group within the Pestivirus genus that is implicated in economic losses for cattle producers due to both acute and persistent infections. Pestivirus strains exist as quasispecies (swarms of individual viruses) in infected animals and the viral populations making up the quasispecies differ widely in size and diversity in each animal. In the present study the viral quasispecies circulating in persistently infected (PI) calves, generated and maintained under experimental conditions using two different 'HoBi' like strains, was observed over time. An increase in genetic variability and the development of certain mutations was observed over time. Mutations observed included the loss of a putative N-linked glycosylation site in the E2 region and the change of specific residues in E1/E2. It is hypothesized that these changes may be the results on continued adaption of the pestivirus to individual hosts. This is the first study characterizing variation in the viral swarms of animals persistently infected with HoBi-like viruses over time. Studies of the shifts in PI viral swarms will contribute to our understanding of the host and viral mechanisms that function in the maintenance of pestivirus persistent infections. PMID- 27693290 TI - Recent advances in inferring viral diversity from high-throughput sequencing data. AB - Rapidly evolving RNA viruses prevail within a host as a collection of closely related variants, referred to as viral quasispecies. Advances in high-throughput sequencing (HTS) technologies have facilitated the assessment of the genetic diversity of such virus populations at an unprecedented level of detail. However, analysis of HTS data from virus populations is challenging due to short, error prone reads. In order to account for uncertainties originating from these limitations, several computational and statistical methods have been developed for studying the genetic heterogeneity of virus population. Here, we review methods for the analysis of HTS reads, including approaches to local diversity estimation and global haplotype reconstruction. Challenges posed by aligning reads, as well as the impact of reference biases on diversity estimates are also discussed. In addition, we address some of the experimental approaches designed to improve the biological signal-to-noise ratio. In the future, computational methods for the analysis of heterogeneous virus populations are likely to continue being complemented by technological developments. PMID- 27693291 TI - C-terminal domain on the outer surface of the Macrobrachium rosenbergii nodavirus capsid is required for Sf9 cell binding and internalization. AB - We have shown that Macrobrachium rosenbergii nodavirus (MrNV) was able to infect Sf9 cells and that MrNV virus-like particles (MrNV-VLPs) were capable nanocontainers for delivering nucleic acid-based materials. Here, we demonstrated that chymotryptic removal of a C-terminal peptide and its truncated variant (F344 MrNV-VLPs) exhibited a drastically reduced ability to interact and internalize into Sf9 cells. Electron microscopic observations revealed that the loss of C terminal domain either from enzyme hydrolysis or genetic truncation did not affect the generated MrNV-VLPs' icosahedral conformation, but did drastically affect the VLPs' internalization ability into Sf9 cells. Homology-based modelling of the MrNV capsid with other icosahedral capsid models revealed that this chymotrypsin-sensitive C-terminal domain was not only exposed on the capsid surface, but also constituted the core of the viral capsid protrusion. These results therefore suggest the importance of the C-terminal domain as a structure for targeted cell interaction which is presumably localized at the protruding domain. This work thus provided the functional insights into the role of the MrNV C-terminal domain in viral entry into Sf9 cells and lead to the development of strategies in combatting MrNV infection in susceptible cells. PMID- 27693292 TI - Predictors and patterns of weight gain during treatment for tuberculosis in the United States of America. AB - OBJECTIVES: Patients with tuberculosis (TB) often present with weight loss. Lack of weight gain with TB treatment has been associated with treatment failure. The purpose of this study was to examine patterns of weight gain in patients with TB and determine the disease characteristics that predict weight gain. METHODS: This was a retrospective cohort study of adults with TB treated in a county health system in the USA. Demographic, clinical, radiographic, and microbiological data were recorded in addition to monthly weights during treatment. RESULTS: Overall, patients had a significant change in weight over the course of treatment (p<0.0001). After 2 months of treatment, 31.9% of patients had gained at least 5% body weight; by the end of treatment, 62.4% of patients had gained at least 5% weight. Patients who gained weight did so in a linear fashion throughout treatment. Cavitary and extensive disease, a positive smear, and a positive culture were predictors of weight gain (p<0.05). No patients had relapses during the time period of the study. CONCLUSIONS: Only a subset of patients treated for TB gain significant weight. A greater burden of disease was predictive of weight gain. PMID- 27693293 TI - NIRS-EEG joint imaging during transcranial direct current stimulation: Online parameter estimation with an autoregressive model. AB - BACKGROUND: Transcranial direct current stimulation (tDCS) has been shown to perturb both cortical neural activity and hemodynamics during (online) and after the stimulation, however mechanisms of these tDCS-induced online and after effects are not known. Here, online resting-state spontaneous brain activation may be relevant to monitor tDCS neuromodulatory effects that can be measured using electroencephalography (EEG) in conjunction with near-infrared spectroscopy (NIRS). METHOD: We present a Kalman Filter based online parameter estimation of an autoregressive (ARX) model to track the transient coupling relation between the changes in EEG power spectrum and NIRS signals during anodal tDCS (2mA, 10min) using a 4*1 ring high-definition montage. RESULTS: Our online ARX parameter estimation technique using the cross-correlation between log (base-10) transformed EEG band-power (0.5-11.25Hz) and NIRS oxy-hemoglobin signal in the low frequency (<=0.1Hz) range was shown in 5 healthy subjects to be sensitive to detect transient EEG-NIRS coupling changes in resting-state spontaneous brain activation during anodal tDCS. Conventional sliding window cross-correlation calculations suffer a fundamental problem in computing the phase relationship as the signal in the window is considered time-invariant and the choice of the window length and step size are subjective. Here, Kalman Filter based method allowed online ARX parameter estimation using time-varying signals that could capture transients in the coupling relationship between EEG and NIRS signals. CONCLUSION: Our new online ARX model based tracking method allows continuous assessment of the transient coupling between the electrophysiological (EEG) and the hemodynamic (NIRS) signals representing resting-state spontaneous brain activation during anodal tDCS. PMID- 27693294 TI - Assessment of axonal excitability properties in two branches of the human facial nerve. AB - BACKGROUND: Axonal excitability methods have an established role in determining the biophysical properties of human axons in the clinical setting. The translation and refinement of these techniques for application to the facial nerve is important for advancing the pathophysiological understanding of facial nerve disorders. Facial nerve disorders are common and debilitating, yet in most cases diagnosis is based on clinical judgment alone. The pathophysiology of most causes of facial palsy remains unclear. NEW METHOD: Novel techniques for the acquisition of facial nerve excitability properties were developed based on anatomical and surgical landmarks for two facial nerve branches. Zygomatic branch stimulation with nasalis recording and marginal mandibular branch stimulation with depressor angularis oris (DAO) recording were used. Comparisons were made between the two branches and with the median nerve, and the relationship between gender, age and nerve properties was explored through subgroup analysis. RESULTS: A full set of recordings were obtained in all participants across a wide age range. 27 nasalis recordings and 19 DAO recordings were completed and analysed. The studies were well tolerated in all participants. Excitability parameters were found to be similar for both branches of the facial nerve. COMPARISON WITH EXISTING METHOD: Axonal excitability has proven to be of significant value in the study of motor and sensory neuropathy, however previous experience with facial nerve techniques has been limited. This study establishes normative data and a consistent technique for the application of axonal excitability testing to the study of facial nerve properties. PMID- 27693295 TI - Strength of obesity prevention interventions in early care and education settings: A systematic review. AB - TIME AND PLACE OF STUDY: 2010-2015; INTERNATIONAL: Given the high levels of obesity in young children, numbers of children in out-of-home care, and data suggesting a link between early care and education (ECE) participation and overweight/obesity, obesity prevention in ECE settings is critical. As the field has progressed, a number of interventions have been reviewed yet there is a need to summarize the data using more sophisticated analyses to answer questions on the effectiveness of interventions. We conducted a systematic review of obesity prevention interventions in center-based ECE settings published between 2010 and 2015. Our goal was to identify promising intervention characteristics associated with successful behavioral and anthropometric outcomes. A rigorous search strategy resulted in 43 interventions that met inclusion criteria. We developed a coding strategy to assess intervention strength, used a validated study quality assessment tool, and presented detailed descriptive information about interventions (e.g., target behaviors, intervention strategies, and mode of delivery). Intervention strength was positively correlated with reporting of positive anthropometric outcomes for physical activity, diet, and combined interventions, and parent engagement components increased the strength of these relationships. Study quality was modestly related to percent successful healthy eating outcomes. Relationships between intervention strength and behavioral outcomes demonstrated negative relationships for all behavioral outcomes. Specific components of intervention strength (number of intervention strategies, potential impact of strategies, frequency of use, and duration of intervention) were correlated with some of the anthropometric and parent engagement outcomes. The review provided tentative evidence that multi-component, multi-level ECE interventions with parental engagement are most likely to be effective with anthropometric outcomes. PMID- 27693296 TI - Risk management and statistical multivariate analysis approach for design and optimization of satranidazole nanoparticles. AB - Rapidly evolving technical and regulatory landscapes of the pharmaceutical product development necessitates risk management with application of multivariate analysis using Process Analytical Technology (PAT) and Quality by Design (QbD). Poorly soluble, high dose drug, Satranidazole was optimally nanoprecipitated (SAT NP) employing principles of Formulation by Design (FbD). The potential risk factors influencing the critical quality attributes (CQA) of SAT-NP were identified using Ishikawa diagram. Plackett-Burman screening design was adopted to screen the eight critical formulation and process parameters influencing the mean particle size, zeta potential and dissolution efficiency at 30min in pH7.4 dissolution medium. Pareto charts (individual and cumulative) revealed three most critical factors influencing CQA of SAT-NP viz. aqueous stabilizer (Polyvinyl alcohol), release modifier (Eudragit(r) S 100) and volume of aqueous phase. The levels of these three critical formulation attributes were optimized by FbD within established design space to minimize mean particle size, poly dispersity index, and maximize encapsulation efficiency of SAT-NP. Lenth's and Bayesian analysis along with mathematical modeling of results allowed identification and quantification of critical formulation attributes significantly active on the selected CQAs. The optimized SAT-NP exhibited mean particle size; 216nm, polydispersity index; 0.250, zeta potential; -3.75mV and encapsulation efficiency; 78.3%. The product was lyophilized using mannitol to form readily redispersible powder. X-ray diffraction analysis confirmed the conversion of crystalline SAT to amorphous form. In vitro release of SAT-NP in gradually pH changing media showed <20% release in pH1.2 and pH6.8 in 5h, while, complete release (>95%) in pH7.4 in next 3h, indicative of burst release after a lag time. This investigation demonstrated effective application of risk management and QbD tools in developing site-specific release SAT-NP by nanoprecipitation. PMID- 27693298 TI - Preparation, characterization and in-vivo evaluation of microemulsions containing tamoxifen citrate anti-cancer drug. AB - The aim of this study was to prepare and characterize a new nanocarrier for oral delivery of tamoxifen citrate (TMC) as a lipophilic oral administrated drug. This drug has low oral bioavailability due to its low aqueous solubility. To enhance the solubility of this drug, the microemulsion system was applied in form of oil in-water. Sesame oil and Tween 80 were used as drug solvent oil and surfactant, respectively. Two different formulations were prepared for this purpose. The first formulation contained edible glycerin as co-surfactant and the second formulation contained Span 80 as a mixed surfactant. The results of characterization showed that the mean droplet size of drug-free samples was in the range of 16.64-64.62nm with a PDI value of <0.5. In a period of 6months after the preparation of samples, no phase sedimentation was observed, which confirmed the high stability of samples. TMC with a mass ratio of 1% was loaded in the selected samples. No significant size enlargement and drug precipitation were observed 6months after drug loading. In addition, the drug release profile at experimental environments in buffers with pH=7.4 and 5.5 showed that in the first 24h, 85.79 and 100% of the drug were released through the first formulation and 76.63 and 66.42% through the second formulation, respectively. The in-vivo results in BALB/c female mice showed that taking microemulsion form of drug caused a significant reduction in the growth rate of cancerous tumor and weight loss of the mice compared to the consumption of commercial drug tablets. The results confirmed that the new formulation of TMC could be useful for breast cancer treatment. PMID- 27693297 TI - Synthesis, characterization and liver targeting evaluation of self-assembled hyaluronic acid nanoparticles functionalized with glycyrrhetinic acid. AB - Recently, polymeric materials with multiple functions have drawn great attention as the carrier for drug delivery system design. In this study, a series of multifunctional drug delivery carriers, hyaluronic acid (HA)-glycyrrhetinic acid (GA) succinate (HSG) copolymers were synthesized via hydroxyl group modification of hyaluronic acid. It was shown that the HSG nanoparticles had sub-spherical shape, and the particle size was in the range of 152.6-260.7nm depending on GA graft ratio. HSG nanoparticles presented good short term and dilution stability. MTT assay demonstrated all the copolymers presented no significant cytotoxicity. In vivo imaging analysis suggested HSG nanoparticles had superior liver targeting efficiency and the liver targeting capacity was GA graft ratio dependent. The accumulation of DiR (a lipophilic, NIR fluorescent cyanine dye)-loaded HSG-6, HSG 12, and HSG-20 nanoparticles in liver was 1.8-, 2.1-, and 2.9-fold higher than that of free DiR. The binding site of GA on HA may influence liver targeting efficiency. These results indicated that HSG copolymers based nanoparticles are potential drug carrier for improved liver targeting. PMID- 27693301 TI - Unified and simple understanding for the evolution of conditional cooperators. AB - Cooperation is a mysterious phenomenon which is observed in this world. The potential explanation is a repeated interaction. Cooperation is established if individuals meet the same opponent repeatedly and cooperate conditionally. Previous studies have analyzed the following four as characters of conditional cooperators mainly. (i) niceness (i.e., when a conditional cooperator meets an opponent in the first place, he (she) cooperates or defects), (ii) optimism (when a conditional cooperator meets an opponent in the past, but he (she) did not get access to information about the opponent's behavior in the previous round, he (she) cooperates or defects), (iii) generosity (even when a conditional cooperator knows that an opponent defected in the previous round, he (she) cooperates or defects) and (iv) retaliation (a conditional cooperator cooperates with a cooperator with a higher probability than with a defector). Previous works deal with these four characters mainly. However, these four characters basically have been regarded as distinct topics and unified understanding has not been done fully. Here we, by studying the iterated prisoner's dilemma game (in particular, additive games) and using evolutionarily stable strategy (ESS) analysis, find that when retaliation is large, the condition under which conditional cooperators are stable against the invasion by an unconditional defector is loose, while none of "niceness", "optimism", and "generosity" makes impact on the condition under which conditional cooperators are stable against an invasion by an unconditional defector. Furthermore, we show that we can understand "niceness", "optimism", and "generosity" uniformly by using one parameter indicating "cooperative", and when the conditional cooperators have large "retaliation" enough to resist an invasion by an unconditional defector, natural selection favors more "cooperative" conditional cooperators to invade the resident conditional cooperative strategy. Moreover, we show that these results are robust even when taking the existence of mistakes in behavior into consideration.

AB - Three Physiologically Based Pharmacokinetic software packages (GI-Sim, Simcyp(r) Simulator, and GastroPlusTM) were evaluated as part of the Innovative Medicine Initiative Oral Biopharmaceutics Tools project (OrBiTo) during a blinded "bottom up" anticipation of human pharmacokinetics. After data analysis of the predicted vs. measured pharmacokinetics parameters, it was found that oral bioavailability (Foral) was underpredicted for compounds with low permeability, suggesting improper estimates of intestinal surface area, colonic absorption and/or lack of intestinal transporter information. Foral was also underpredicted for acidic compounds, suggesting overestimation of impact of ionisation on permeation, lack of information on intestinal transporters, or underestimation of solubilisation of weak acids due to less than optimal intestinal model pH settings or underestimation of bile micelle contribution. Foral was overpredicted for weak bases, suggesting inadequate models for precipitation or lack of in vitro precipitation information to build informed models. Relative bioavailability was underpredicted for both high logP compounds as well as poorly water-soluble compounds, suggesting inadequate models for solubility/dissolution, underperforming bile enhancement models and/or lack of biorelevant solubility measurements. These results indicate areas for improvement in model software, modelling approaches, and generation of applicable input data. However, caution is required when interpreting the impact of drug-specific properties in this exercise, as the availability of input parameters was heterogeneous and highly variable, and the modellers generally used the data "as is" in this blinded bottom-up prediction approach. PMID- 27693300 TI - A Comparison of Aerosolization and Homogenization Techniques for Production of Alginate Microparticles for Delivery of Corticosteroids to the Colon. AB - Alginate microparticles incorporating hydrocortisone hemisuccinate were produced by aerosolization and homogenization methods to investigate their potential for colonic drug delivery. Microparticle stabilization was achieved by CaCl2 crosslinking solution (0.5 M and 1 M), and drug loading was accomplished by diffusion into blank microparticles or by direct encapsulation. Homogenization method produced smaller microparticles (45-50 MUm), compared to aerosolization (65-90 MUm). High drug loadings (40% wt/wt) were obtained for diffusion-loaded aerosolized microparticles. Aerosolized microparticles suppressed drug release in simulated gastric fluid (SGF) and simulated intestinal fluid (SIF) prior to drug release in simulated colonic fluid (SCF) to a higher extent than homogenized microparticles. Microparticles prepared using aerosolization or homogenization (1 M CaCl2, diffusion loaded) released 5% and 17% of drug content after 2 h in SGF and 4 h in SIF, respectively, and 75% after 12 h in SCF. Thus, aerosolization and homogenization techniques show potential for producing alginate microparticles for colonic drug delivery in the treatment of inflammatory bowel disease. PMID- 27693302 TI - A new parametric method to smooth time-series data of metabolites in metabolic networks. AB - Mathematical modeling of large-scale metabolic networks usually requires smoothing of metabolite time-series data to account for measurement or biological errors. Accordingly, the accuracy of smoothing curves strongly affects the subsequent estimation of model parameters. Here, an efficient parametric method is proposed for smoothing metabolite time-series data, and its performance is evaluated. To simplify parameter estimation, the method uses S-system-type equations with simple power law-type efflux terms. Iterative calculation using this method was found to readily converge, because parameters are estimated stepwise. Importantly, smoothing curves are determined so that metabolite concentrations satisfy mass balances. Furthermore, the slopes of smoothing curves are useful in estimating parameters, because they are probably close to their true behaviors regardless of errors that may be present in the actual data. Finally, calculations for each differential equation were found to converge in much less than one second if initial parameters are set at appropriate (guessed) values. PMID- 27693303 TI - Mathematical analysis and validation of an exactly solvable model for upstream migration of fish schools in one-dimensional rivers. AB - Upstream migration of fish schools in 1-D rivers as an optimal control problem is formulated where their swimming velocity and the horizontal oblateness are taken as control variables. The objective function to be maximized through a migration process consists of the biological and ecological profit to be gained at the upstream-end of a river, energetic cost of swimming against the flow, and conceptual cost of forming a school. Under simplified conditions where the flow is uniform in both space and time and the profit to be gained at the goal of migration is sufficiently large, the optimal control variables are determined from a system of algebraic equations that can be solved in a cascading manner. Mathematical analysis of the system reveals that the optimal controls are uniquely found and the model is exactly solvable under certain conditions on the functions and parameters, which turn out to be realistic and actually satisfied in experimental fish migration. Identification results of the functional shapes of the functions and the parameters with experimentally observed data of swimming schools of Plecoglossus altivelis (Ayu) validate the present mathematical model from both qualitative and quantitative viewpoints. The present model thus turns out to be consistent with the reality, showing its potential applicability to assessing fish migration in applications. PMID- 27693304 TI - Evaluation of antimicrobial, cytotoxic, and hemolytic activities from venom of the spider Lasiodora sp. AB - This study characterized the protein/peptide profile of venom isolated from the spider Lasiodora sp. (Mygalomorphae, Theraphosidae) found in northeastern Brazil and determined its antimicrobial activity, toxicity against human cells, and hemolytic activity. Protein concentration of the Lasiodora sp. venom was 4.53 +/- 0.38 mg/mL. SDS-PAGE showed proteins with molecular masses up to 75 kDa, some of which contained disulfide bridges. RP-HPLC analysis separate at least 12 peaks that were identified by mass spectrometry as peptides U1-theraphotoxin-Lp1a (lasiotoxin-1), U1-theraphotoxin-Lp1c (lasiotoxin-3), U3-theraphotoxin-Lsp1a (LTx5), and omega-theraphotoxin-Asp3a as well as the proteins phospholipase A2 (PLA2) and hyaluronidase. The crude venom exhibited bactericidal effect against Aeromonas sp., Bacillus subtilis, and Micrococcus luteus and fungicidal effect against Candida parapsilosis and Candida albicans. In addition, the venom exerted bacteriostatic effect against Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus and fungistatic effect against Candida tropicalis and Candida krusei. The minimum inhibitory (MIC), minimum bactericidal (MBC), and minimum fungicidal (MFC) concentrations ranged from 3.9 to 500 MUg/mL. The Lasiodora sp. venom decreased the viability of human peripheral blood mononuclear cells (PBMCs) by 50%-90% at concentrations of 0.1, 1, 10, and 100 MUg/mL, promoting apoptosis of these cells. On the other hand, the venom showed weak hemolytic activity against Mus musculus erythrocytes (EC50: 757 MUg/mL). In conclusion, the Lasiodora sp. spider venom is a rich source of antimicrobial agents. Future studies will focus on identifying antimicrobial agents present in this venom and evaluating whether these agents contribute to its cytotoxic effects against PBMCs. PMID- 27693305 TI - Inability to detect free cylindrospermopsin in spiked aquatic organism extracts plausibly suggests protein binding. AB - Even though the frequency and prevalence of cylindrospermopsin producing cyanobacteria are increasing, several publications have reported the absence of free cylindrospermopsin bioaccumulation in aquatic food chains. Cylindrospermopsin modification by protein binding has been suggested, however, only one publication has investigated this with eukaryotic reticulocyte lysate and concluded that cylindrospermopsin binds non-covalently to soluble proteins larger than 100 kDa associated with eukaryotic translation. With this as the extent of knowledge regarding cylindrospermopsin binding, the present study aimed to determine whether cylindrospermopsin binding also occurred with other proteins. In the present study, proteins from various organisms were extracted, incubated with cylindrospermopsin, and the amount of free cylindrospermopsin was determined by liquid chromatography tandem mass spectroscopy. Additionally, cylindrospermopsin binding to various ammonium sulfate precipitation fractions of Egeria densa protein, as well as with selected amino acids was investigated. We find that the percentage of free cylindrospermopsin varied with exposure to various animal and plant proteins as well as with various fractions of proteins but found no binding with single amino acids. PMID- 27693306 TI - Diverse Intestinal Bacteria Contain Putative Zwitterionic Capsular Polysaccharides with Anti-inflammatory Properties. AB - Zwitterionic capsular polysaccharides (ZPSs) are bacterial products that modulate T cells, including inducing anti-inflammatory IL-10-secreting T regulatory cells (Tregs). However, only a few diverse bacteria are known to modulate the host immune system via ZPS. We present a genomic screen for bacteria encoding ZPS molecules. We identify diverse host-associated bacteria, including commensals and pathogens with known anti-inflammatory properties, with the capacity to produce ZPSs. Human mononuclear cells stimulated with lysates from putative ZPS-producing bacteria induce significantly greater IL-10 production and higher proportions of Tregs than lysates from non-ZPS-encoding relatives or a commensal strain of Bacteroides cellulosilyticus in which a putative ZPS biosynthetic operon was genetically disrupted. Similarly, wild-type B. cellulosilyticus DSM 14838, but not a close relative lacking a putative ZPS, attenuated experimental colitis in mice. Collectively, this screen identifies bacterial strains that may use ZPSs to interact with the host as well as those with potential probiotic properties. PMID- 27693307 TI - Stable Engraftment of Bifidobacterium longum AH1206 in the Human Gut Depends on Individualized Features of the Resident Microbiome. AB - Live bacteria (such as probiotics) have long been used to modulate gut microbiota and human physiology, but their colonization is mostly transient. Conceptual understanding of the ecological principles as they apply to exogenously introduced microbes in gut ecosystems is lacking. We find that, when orally administered to humans, Bifidobacterium longum AH1206 stably persists in the gut of 30% of individuals for at least 6 months without causing gastrointestinal symptoms or impacting the composition of the resident gut microbiota. AH1206 engraftment was associated with low abundance of resident B. longum and underrepresentation of specific carbohydrate utilization genes in the pre treatment microbiome. Thus, phylogenetic limiting and resource availability are two factors that control the niche opportunity for AH1206 colonization. These findings suggest that bacterial species and functional genes absent in the gut microbiome of individual humans can be reestablished, providing opportunities for precise and personalized microbiome reconstitution. PMID- 27693308 TI - Zika Virus Infection Induces Cranial Neural Crest Cells to Produce Cytokines at Levels Detrimental for Neurogenesis. AB - Zika virus (ZIKV) infection during pregnancy is linked to microcephaly, which is attributed to infection of developing brain structures. ZIKV infects neural progenitor cells in vitro, though its effects on other developmentally relevant stem cell populations, including cranial neural crest cells (CNCCs), have not been assessed. CNCCs give rise to most cranial bones and exert paracrine effects on the developing brain. Here, we report that CNCCs are productively infected by ZIKV, but not by the related dengue virus. ZIKV-infected CNCCs undergo limited apoptosis but secrete cytokines that promote death and drive aberrant differentiation of neural progenitor cultures. Addition of two such cytokines, LIF or VEGF, at levels comparable to those secreted by ZIKV-infected CNCCs is sufficient to recapitulate premature neuronal differentiation and apoptotic death of neural progenitors. Thus, our results suggest that CNCC infection by ZIKV may contribute to associated embryopathies through signaling crosstalk between developing face and brain structures. PMID- 27693309 TI - Cryo-FIB-SEM serial milling and block face imaging: Large volume structural analysis of biological tissues preserved close to their native state. AB - Many important biological questions can be addressed by studying in 3D large volumes of intact, cryo fixed hydrated tissues (?10,000MUm3) at high resolution (5-20nm). This can be achieved using serial FIB milling and block face surface imaging under cryo conditions. Here we demonstrate the unique potential of the cryo-FIB-SEM approach using two extensively studied model systems; sea urchin embryos and the tail fin of zebrafish larvae. We focus in particular on the environment of mineral deposition sites. The cellular organelles, including mitochondria, Golgi, ER, nuclei and nuclear pores are made visible by the image contrast created by differences in surface potential of different biochemical components. Auto segmentation and/or volume rendering of the image stacks and 3D reconstruction of the skeleton and the cellular environment, provides a detailed view of the relative distribution in space of the tissue/cellular components, and thus of their interactions. Simultaneous acquisition of secondary and back scattered electron images adds additional information. For example, a serial view of the zebrafish tail reveals the presence of electron dense mineral particles inside mitochondrial networks extending more than 20MUm in depth in the block. Large volume imaging using cryo FIB SEM, as demonstrated here, can contribute significantly to the understanding of the structures and functions of diverse biological tissues. PMID- 27693310 TI - The selective biomarker IL-8 identifies IFTA after kidney transplantation in blood cells. AB - Cellular and antibody-mediated rejection processes and also interstitial fibrosis/tubular atrophy (IFTA) lead to allograft dysfunction and loss. The search for accurate, specific and non-invasive diagnostic tools is still ongoing and essential for successful treatment of renal transplanted patients. Molecular markers in blood cells and serum may serve as diagnostic tools but studies with high patient numbers and differential groups are rare. We validated the potential value of several markers on mRNA level in blood cells and serum protein level in 166 samples from kidney transplanted patients under standard immunosuppressive therapy (steroids+/-mycophenolic acid+/-calcineurin inhibitor) with stable graft function, urinary tract infection (UTI), IFTA, antibody-mediated rejection (ABMR), and T-cell-mediated rejection (TCMR) applying RT-PCR and ELISA. The mRNA expression of RANTES, granulysin, granzyme-B, IP-10, Mic-A and Interferon-gamma in blood cells did not distinguish specifically between the different pathologies. We furthermore discovered that the mRNA expression of the chemokine IL-8 is significantly lower in samples from IFTA patients than in samples from patients with stable graft function (p<0.001), ABMR (p<0.001), Borderline (BL) TCMR (p<0.001), tubulo-interstitial TCMR (p<0.001) and vascular TCMR (p<0.01), but not with UTI. Serum protein concentrations of granzyme-B, Interferon-gamma and IL-8 did not differ between the patient groups, RANTES concentration was significantly different when comparing UTI and ABMR (p<0.01), whereas granulysin, Mic-A and IP-10 measurement differentiated ongoing rejection or IFTA processes from stable graft function but not from each other. The measurement of IL-8 mRNA in blood cells distinguishes clearly between IFTA and other complication after kidney transplantation and could easily be used as diagnostic tool in the clinic.

TAA in association with syringocystadenoma papilliferum (SCP) is exceptional. A 2-year old Tunisian child developed a mixed tumor on the scalp: TAA in association with SCP. Histologically, the tumor consisted of dilated duct-like areas with some apocrine gland-like areas. The superficial part of the tumor was connected to the epidermis and showed the characteristics of SCP. The characteristics and differences in histopathologic and immunohistochemical findings in this mixed tumor are described. PMID- 27693312 TI - The aging face. AB - Advancements in technology and medicine have led to a greater life expectancy and a corresponding increased interest in the mechanisms and prevention of aging. Because of its central role in human perception of age and emotion, the aging face generates a high demand for understanding the etiology of senescence-related changes. There are effective nonsurgical and surgical methods available for those seeking functional or cosmetic facial rejuvenation. PMID- 27693313 TI - A cell-based biosensor for nanomaterials cytotoxicity assessment in three dimensional cell culture. AB - Nanoparticles (NPs) are widely used in consumer and medicinal products. The high prevalence of nanoparticles in the environment raises concerns regarding their effects on human health, but there is limited knowledge about how NPs interact with cells or tissues. Because the European Union has called for a substantial reduction of animal experiments for scientific purposes (Directive 2010/63), increased efforts are required to develop in vitro models to evaluate potentially hazardous agents. Here, we describe a new cell-based biosensor for the evaluation of NPs cytotoxicity. The new biosensor is based on transgenic human hepatoblastoma cells (HepG2) that express a secreted form of alkaline phosphatase (SEAP) as a reporter protein whose expression is induced upon activation of a stress response pathway controlled by the transcription regulator nuclear factor kappaB (NF-kappaB). The NF-kappaB_HepG2 sensor cells were cultured in a Matrigel based three dimensional environment to simulate the in vivo situation. The new biosensor cells offer the advantage of generating fast and reproducible readout at lower concentrations and shorter incubation time than conventional viability assays, avoid possible interaction between nanomaterials and assay compounds, therefore, minimize generation of false positive or negative results and indicate mechanism of toxicity through NF-kappaB signaling. PMID- 27693314 TI - Select putative neurodevelopmental toxins modify SNAP-25 expression in primary cultures of rat cerebellar granule cells. AB - A presynaptic protein SNAP-25 belonging to SNARE complex which is instrumental in intracellular vesicular trafficking and exocytosis, has been implicated in hyperactivity and cognitive abilities in some neuropsychiatric disorders. The unclear etiology of the behavior disrupting neurodevelopmental disabilities in addition to genetic causes most likely involves environmental factors. The aim of this in vitro study was to test if various suspected developmental neurotoxins can alter SNAP-25 mRNA and protein expression in neurons. Real-time PCR and Western blotting analyses were used to assess SNAP-25 mRNA and protein levels in primary cultures of rat cerebellar granule cells (CGCs). The test substances: tetrabromobisphenol-A (TBBPA), thimerosal (TH), silver nanoparticles (NAg), valproic acid (VPA) and thalidomide (THAL), were administered to CGC cultures at subtoxic concentrations for 24h. The results demonstrated that SNAP-25 mRNA levels were increased by 49 and 66% by TBBPA and THAL, respectively, whereas VPA and NAg reduced these levels to 48 and 64% of the control, respectively. The SNAP 25 protein content in CGCs was increased by 79% by TBBPA, 25% by THAL and 21% by NAg; VPA and TH reduced these levels to 73 and 69% of the control, respectively. The variety of changes in SNAP-25 expression on mRNA and protein level suggests the diversity of the mechanism of action of the test substances. This initial study provided no data on concentration-effect relations and on functional changes in CGCs. However it is the first to demonstrate the effect of different compounds that are suspected of causing neurodevelopmental disabilities on SNAP 25 expression. These results suggest that this protein may be a common target for not only inherited but also environmental modifications linked to behavioral deficits in neurodevelopmental disabilities. PMID- 27693315 TI - Evaluation of tetrabromobisphenol A effects on human glucocorticoid and androgen receptors: A comparison of results from human- with yeast-based in vitro assays. AB - The incidence of immune-related diseases increased over the last years in industrialized countries, suggesting a contribution of environmental factors. Impaired glucocorticoid action has been associated with immune disorders. Thus, there is an increasing interest to identify chemicals disrupting glucocorticoid action. The widely used flame retardant tetrabromobisphenol A (TBBPA) was reported earlier to potently inhibit glucocorticoid receptor (GR) and moderately androgen receptor (AR) activity in yeast-based reporter gene assays. To further characterize possible GR disrupting effects of TBBPA, transactivation experiments using a human HEK-293 cell-based reporter gene assay and cell-free receptor binding experiments were performed in the present study. Both, transactivation and GR binding experiments failed to detect any activity of TBBPA on GR function. Molecular docking calculations supported this observation. Additionally, the current study could confirm the antiandrogenic activity of TBBPA seen in the yeast assay, although the effect was an order of magnitude less pronounced in the HEK-293 cell-based system. In conclusion, TBBPA does not directly affect GR function and, considering its rapid metabolism and low concentrations found in humans, it is unlikely to cause adverse effects by acting through AR. This study emphasizes the use of cell-free assays in combination with cell-based assays for the in vitro evaluation of endocrine disrupting chemicals. PMID- 27693316 TI - Selective scavenging of intra-mitochondrial superoxide corrects diclofenac induced mitochondrial dysfunction and gastric injury: A novel gastroprotective mechanism independent of gastric acid suppression. AB - Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used to treat multiple inflammatory diseases and pain but severe gastric mucosal damage is the worst outcome of NSAID-therapy. Here we report that mitoTEMPO, a mitochondrially targeted superoxide (O2-) scavenger protected as well as healed gastric injury induced by diclofenac (DCF), the most commonly used NSAID. Common existing therapy against gastric injury involves suppression of gastric acid secretion by proton pump inhibitors and histamine H2 receptor antagonists; however, dyspepsia, vitamin B12 deficiency and gastric microfloral dysbalance are the major drawbacks of acid suppression. Interestingly, mitoTEMPO did not inhibit gastric acid secretion but offered gastroprotection by preventing DCF-induced generation of O2 due to mitochondrial respiratory chain failure and by preventing mitochondrial oxidative stress (MOS)-mediated mitopathology. MitoTEMPO even restored DCF stimulated reduced fatty acid oxidation, mitochondrial depolarization and bioenergetic crisis in gastric mucosa. MitoTEMPO also prevented the activation of mitochondrial pathway of apoptosis and MOS-mediated proinflammatory signaling through NF-kappaB by DCF. Furthermore, mitoTEMPO when administered in rats with preformed gastric lesions expedited the healing of gastric injury and the healed stomach exhibited its normal physiology as evident from gastric acid and pepsin secretions under basal or stimulated conditions. Thus, in contrast to the existing antiulcer drugs, mitochondrially targeted O2- scavengers like mitoTEMPO may represent a novel class of gastroprotective molecules that does not affect gastric acid secretion and may be used in combination with DCF, keeping its anti inflammatory action intact, while reducing its gastrodamaging effects. PMID- 27693317 TI - Andrographolide reversed 5-FU resistance in human colorectal cancer by elevating BAX expression. AB - 5-FU is the first line therapy for colorectal cancer, however, treatment effect is often hampered by the development of drug resistance or toxicity at high doses. Andrographolide is a natural diterpenoid from Andrographis paniculata which has anti-bacterial, anti-antiviral and anti-inflammation activities. In the current study, we test the hypothesis that Andrographolide reverses 5-FU resistance in colorectal cancer and examine the underlying mechanism. In vitro and vivo studies indicated that Andrographolide treatment significantly re sensitizes HCT116/5-FUR cells (HCT116 cells which are 5-FU resistant) to cytotoxicity of 5-FU. Mechanism analysis showed that Andrographolide/5-FU co treatment elevated apoptosis level of HCT116/5-FUR cells with highly increased level of BAX. By using biotin-Andrographolide pull down and cellular thermal shift assay, we found out that Andrographolide can directly target to BAX. Andrographolide-BAX interaction prevented BAX degradation, enhancing mitochondria mediated apoptosis thus reversed 5-FU resistance while BAX silence diminished this effect. Further, by analyzing patient samples who received 5-FU involved chemotherapy, we found that expression level of BAX is correlated with PFS. Our results here provide a novel combination treatment strategy, especially for patients with 5-FU-resistant tumors expressing low level of BAX. Meanwhile, we also proposed that BAX expression may be a predicted and prognosis marker of 5-FU involved chemotherapy. PMID- 27693318 TI - Accuracies of fecal calprotectin, lactoferrin, M2-pyruvate kinase, neopterin and zonulin to predict the response to infliximab in ulcerative colitis. AB - BACKGROUND: Fecal markers might predict the response to anti-TNFalpha in ulcerative colitis (UC). AIMS: To compare the performance of fecal calprotectin (fCal), lactoferrin (fLact), M2-PK (fM2-PK), neopterin (fNeo), and zonulin (fZon) to predict the response to therapy in active UC patients. METHODS: Disease activity from 31 consecutive patients with an active UC, treated with infliximab (IFX) was assessed by the Mayo score at baseline and at week 14 and by the partial Mayo score at W52 and stool samples collected for fecal marker measurements at W0, W2, and W14. RESULTS: At W14, 19 patients (61%) were responders to IFX induction. The median levels of fCal, fLact and fM2-PK drop dramatically from baseline to W14 in clinical responders. At W2, fM2-PK, fLact and fCal levels predicted accurately the response to IFX induction. At W14, fLact, fCal, and fM2-PK were individually reliable markers to predict sustained response at W52. The performances of fNeo and fZon were weaker in this setting. CONCLUSIONS: The performance of fM2-PK at W2 to predict response to induction therapy with IFX was superior to that of fLact and fCal, whereas monitoring fLact was the best tool to predict adequately the course of the disease at one year under maintenance IFX in UC. PMID- 27693319 TI - CRISPRi engineering E. coli for morphology diversification. AB - Microbial morphology engineering has recently become interesting for biotechnology. Genes ftsZ and mreB encoding proteins of bacterial fission ring and skeletons, respectively, are essential for cell growth, they both are the most important genes keeping the bacterial shapes including the cell length and width, respectively. Clustered regularly interspaced short palindromic repeats interference, abbreviated as CRISPRi, was for the first time used in this study to regulate expression intensities of ftsZ or/and mreB in E. coli. Five sgRNAs associated with CRISPRi were designed and synthesized, respectively, to target five various locations on genes ftsZ or mreB encoded in the E. coli chromosome, resulting in various reduced expression levels of ftsZ or/and mreB, respectively, forming elongated or/and fatter cells. Repressions on gene expressions of ftsZ or/and mreB could be further intensified by combining various sgRNAs together. It was found that the stronger the repression on genes ftsZ or/and mreB, the longer the E. coli fibers, and the larger the E. coli cells. Combined repressions on expressions of ftsZ and mreB generated long and larger E. coli with diverse morphologies including various sizes of gourds, bars, coccus, spindles, multi angles and ellipsoids. In all cases, accumulations of intracellular biopolyester polyhydroxybutyrate (PHB) were in direct proportional to the intracellular volumes, ranging from 40% to 80% PHB in bacterial cell dry weights, depending on the cell volumes increases by the above CRISPRi applications. PMID- 27693320 TI - CRISPR-Cas9 for the genome engineering of cyanobacteria and succinate production. AB - Cyanobacteria hold promise as a cell factory for producing biofuels and bio derived chemicals, but genome engineering of cyanobacteria such as Synechococcus elongatus PCC 7942 poses challenges because of their oligoploidy nature and long term instability of the introduced gene. CRISPR-Cas9 is a newly developed RNA guided genome editing system, yet its application for cyanobacteria engineering has yet to be reported. Here we demonstrated that CRISPR-Cas9 system can effectively trigger programmable double strand break (DSB) at the chromosome of PCC 7942 and provoke cell death. With the co-transformation of template plasmid harboring the gene cassette and flanking homology arms, CRISPR-Cas9-mediated DSB enabled precise gene integration, ameliorated the homologous recombination efficiency and allowed the use of lower amount of template DNA and shorter homology arms. The CRISPR-Cas9-induced cell death imposed selective pressure and enhanced the chance of concomitant integration of gene cassettes into all chromosomes of PCC 7942, hence accelerating the process of obtaining homogeneous and stable recombinant strains. We further explored the feasibility of engineering cyanobacteria by CRISPR-Cas9-assisted simultaneous glgc knock-out and gltA/ppc knock-in, which improved the succinate titer to 435.0+/-35.0MUg/L, an ~11-fold increase when compared with that of the wild-type cells. These data altogether justify the use of CRISPR-Cas9 for genome engineering and manipulation of metabolic pathways in cyanobacteria. PMID- 27693321 TI - What Is A Normal Intestinal Mucosa?

PMID- 27693324 TI - Long non-coding RNA TUG1 regulates ovarian cancer proliferation and metastasis via affecting epithelial-mesenchymal transition. AB - Ovarian cancer is the fifth leading cause of cancer-related death in women worldwide, and recent studies have highlighted the role of long non-coding RNAs (lncRNAs) in cancer development. However, the role of lncRNAs in ovarian cancer is largely unclear. In this study, we focused on the taurine up-regulated gene 1 (TUG1) and examined its molecular mechanism in ovarian cancer. Here, we reported that TUG1 was up-regulated in ovarian cancer tissues and ovarian cancer cells, and TUG1 expression was positively correlated with tumor grade and FIGO stage. In vitro functional assays (CCK-8 assay, colony formation assay, and cell invasion assay) revealed that knock-down of TUG1 by small RNA inference significantly inhibited cell proliferation, colony formation and cell invasion in ovarian cancer cells. Further experiment showed that knock-down of TUG1 induced cell apoptosis and altered the protein expression levels of apoptosis-related mediators in ovarian cancer cells. More importantly, knock-down of TUG1 also reversed epithelial-mesenchymal transition in ovarian cancer. In summary, our results suggest that knock-down of TUG1 may represent a novel therapeutic strategy for the treatment of ovarian cancer. PMID- 27693325 TI - Adverse tissue reactions after total hip arthroplasty. AB - Hip arthroplasty is commonly performed on patients with debilitating hip disease to relieve symptoms and improve quality of life. Generally, long-term success rates are excellent. However, a subset of patients requires revision due to prosthesis failure. A wide array of microscopic findings can be seen in surrounding tissues and many of the findings are etiologically nonspecific. The aim of this review is to discuss the etiologies and accompanying adverse tissue reactions seen with prosthesis failure, including the findings seen in aseptic lymphocyte-dominated vasculitis-associated lesion. Aseptic lymphocyte-dominated vasculitis-associated lesion is an important diagnostic consideration as its proposed pathogenesis is a type VI hypersensitivity response to metal ions. In addition, we also propose a diagnostic algorithm that incorporates clinical and histopathologic findings to suggest an etiologic cause. This proposed algorithm may be clinically useful as, to date, there is no consensus on nomenclature. PMID- 27693323 TI - Interleukin 1beta Mediates Intestinal Inflammation in Mice and Patients With Interleukin 10 Receptor Deficiency. AB - Interleukin 10 receptor (IL10R)-deficient mice develop spontaneous colitis and, similarly, patients with loss-of-function mutations in IL10R develop severe infant-onset inflammatory bowel disease. Loss of IL10R signaling in mouse and human macrophages is associated with increased production of interleukin 1beta. We demonstrated that innate immune production of IL1beta mediates colitis in IL10R-deficient mice. Transfer of Il1r1-/- CD4+ T cells into Rag1-/-/Il10rb-/- mice reduced the severity of their colitis (compared to mice that received CD4+ T cells that express IL1R), accompanied by decreased production of interferon gamma, tumor necrosis factor-alpha, and IL17A. In macrophages from mice without disruption of IL10R signaling or from healthy humans (controls), incubation with IL10 reduced canonical activation of the inflammasome and production of IL1beta through transcriptional and post-translational regulation of NLRP3. Lipopolysaccharide and adenosine triphosphate stimulation of macrophages from Il10rb-/- mice or IL10R-deficient patients resulted in increased production of IL1beta. Moreover, in human IL10R-deficient macrophages, lipopolysaccharide stimulation alone triggered IL1beta secretion via non-canonical, caspase 8 dependent activation of the inflammasome. We treated 2 IL10R-deficient patients with severe and treatment-refractory infant-onset inflammatory bowel disease with the IL1-receptor antagonist anakinra. Both patients had marked clinical, endoscopic, and histologic responses after 4-7 weeks. This treatment served as successful bridge to allogeneic hematopoietic stem cell transplantation in 1 patient. Our findings indicate that loss of IL10 signaling leads to intestinal inflammation, at least in part, through increased production of IL1 by innate immune cells, leading to activation of CD4+ T cells. Agents that block IL1 signaling might be used to treat patients with inflammatory bowel disease resulting from IL10R deficiency.

AB - Generation of reactive oxygen species (ROS) and failure to maintain an appropriate redox balance contribute to viral pathogenesis. Nuclear factor E2 related factor 2 (Nrf2) is an important transcription factor that plays a pivotal role in maintaining intracellular homoeostasis and coping with invasive pathogens by coordinately activating a series of cytoprotective genes. Previous studies indicated that the transcription and expression levels of Nrf2 were up-regulated in SVCV-infected EPC cells with the unknown mechanism(s). In this study, the interactions between the Nrf2-ARE signalling pathway and SVCV replication were investigated, which demonstrated that SVCV infection induced accumulation of ROS as well as protein carbonyl groups and 8-OHdG, accompanied by the up-regulation of Nrf2 and its downstream genes. At the same time, the activation of Nrf2 with D, l-sulforaphane (SFN) and CDDO-Me could repress the replication of SVCV, and knockdown of Nrf2 by siRNA could promote the replication of SVCV. Taken together, these observations indicate that the Nrf2-ARE signal pathway activates a passive defensive response upon SVCV infection. The conclusions presented here suggest that targeting the Nrf2 pathway has potential for combating SVCV infection.

AB - A novel metallothionein (MT) gene from the Pacific abalone H. discus hannai was characterized and its mRNA expression patterns (tissue distribution, developmental expression and differential expression in responsive to various in vivo stimulatory treatments) were examined. Abalone MT shares conserved structural features with previously known gastropod orthologs at both genomic (i.e., tripartite organization) and amino acid (conserved Cys motifs) levels. The 5'-flanking regulatory region of abalone MT gene displayed various transcription factor binding motifs particularly including ones related with metal regulation and stress/immune responses. Tissue distribution and basal expression patterns of MT mRNAs indicated a potential association between ovarian MT expression and sexual maturation. Developmental expression pattern suggested the maternal contribution of MT mRNAs to embryonic and early larval developments. Abalone MT mRNAs could be significantly induced by various heavy metals in different tissues (gill, hepatopancreas, muscle and hemocyte) in a tissue- and/or metal-dependent fashion. In addition, the abalone MT gene was highly modulated in responsive to other non-metal, stimulatory treatments such as immune challenge (LPS, polyI:C and bacterial injections), hypoxia (decrease from normoxia 8 ppm-2 ppm), thermal elevation (increase from 20 degrees C to 30 degrees C), and xenobiotic exposure (250 ppb of 17alpha-ethynylestradiol and 0.25 ppb of 2,3,7,8 tetrachlorodibenzodioxin) where differential expression patterns were toward either up- or down-regulation depending on types of stimulations and tissues examined. Taken together, our results highlight that MT is a multifunctional effector playing in wide criteria of cellular pathways especially associated with development and stress responses in this abalone species.

PMID- 27693326 TI - Imaging of radicals following injury or acute stress in peripheral nerves with activatable fluorescent probes. AB - Peripheral nerve injury evokes a complex cascade of chemical reactions including generation of molecular radicals. Conversely, the reactions within nerve induced by stress are difficult to directly detect or measure to establish causality. Monitoring these reactions in vivo would enable deeper understanding of the nature of the injury and healing processes. Here, we utilized near-infrared fluorescence molecular probes delivered via intra-neural injection technique to enable live, in vivo imaging of tissue response associated with nerve injury and stress. These initially quenched fluorescent probes featured specific sensitivity to hydroxyl radicals and become fluorescent upon encountering reactive oxygen species (ROS). Intraneurally delivered probes demonstrated rapid activation in injured rat sciatic nerve but minimal activation in normal, uninjured nerve. In addition, these probes reported activation within sciatic nerves of living rats after a stress caused by a pinprick stimulus to the abdomen. This imaging approach was more sensitive to detecting changes within nerves due to the induced stress than other techniques to evaluate cellular and molecular changes. Specifically, neither histological analysis of the sciatic nerves, nor the expression of pain and stress associated genes in dorsal root ganglia could provide statistically significant differences between the control and stressed groups. Overall, the results demonstrate a novel imaging approach to measure ROS in addition to the impact of ROS within nerve in live animals.

PMID- 27693332 TI - Lymphoproliferative response after stimulation with soluble leishmania antigen (SLA) as a predictor of visceral leishmaniasis (VL) relapse in HIV+ patients. AB - The introduction of HAART resulted in the decrease of Leishmania/HIV co-infection cases; nevertheless, the number of relapses remains high and secondary prophylaxis is recommended. However, secondary prophylaxis is not necessary in all patients, and presents a high risk of toxicity and an elevated cost. Our aim was to study whether specific cellular response to Leishmania infantum (measured by cell proliferation response after stimulation with soluble Leishmania antigen (SLA)), could be a useful tool to attempt a secondary prophylaxis withdrawal. In June 2009 an outbreak of leishmaniasis by Leishmania infantum was declared in the southeast of Madrid, and since January 2013, we recruited 10 HIV+ patients that had been treated for visceral leishmaniasis. 6 patients had positive SLA-cell proliferation test. The mean CD4 cell counts of those patients with positive SLA were 140 cel/mm3 and 40 cel/mm3 in those with negative SLA test. 3 patients with positive SLA-cell proliferation test (CD4 count: 336, 307, 625) were not on prophylaxis, and the other 3 patients (CD4 count: 152, 189, 359) were on secondary prophylaxis that was withdrawn after the positive SLA-cell proliferation test with no posterior relapses (mean follow up 60 weeks). From the 4 patients, which had negative SLA-cell proliferation test and continued on prophylaxis, 3 had positive PCR for Leishmania at the end of the follow-up and 2 presented clinical relapses. The performance of SLA-cell proliferation test can be a useful tool that can permit us to try withdrawal of the prophylaxis in Leishmania/HIV co-infected patients with low CD4+ counts under clinical supervision, diminishing risk of toxicity and cost.

AB - Ecohealth projects are designed to garner ownership among all stakeholders, such as researchers, communities, local leadership and policy makers. Ideally, designs should ensure that implementation goes smoothly and that findings from studies benefit the stakeholders, particularly bringing changes to the communities researched. Paradoxically, the process is fraught with challenges associated with implementation. Notwithstanding these challenges, evidence from projects implemented in southern Africa justify the need to invest in the subject of ecohealth. This paper describes and discusses a principal investigator's experience of leading ecohealth projects in Zimbabwe between 2002 and 2005, in Botswana between 2010 and 2014 and in South Africa (ongoing). The discourse is centred on issues of project management and leadership, transdisciplinarity, students' involvement, data management, community engagement, dissemination of research findings and the role of institutions in project management and implementation. The paper concludes that the ecohealth approach is valuable and should be encouraged making the following recommendations; 1) principal investigators must have a good understanding of socio-ecological systems, have excellent project management and writing skills, 2) more than one PI should be involved in the day-to-day running of the project in order to avoid disruption of project activities in the event that the PI leaves the project before it ends, 3) researchers should be trained in ecohealth principles and methodologies at the time of building the research teams, 4) full proposals should be developed with active participation of communities and stakeholders in order to develop a shared vision, 5) involvement of postdoctoral fellows and dedicated researchers with postgraduate students should be encouraged to avoid situations where some objectives are not fully addressed because of the narrow nature of students' work; and 6) citizen science should be encouraged to empower communities and ensure that certain activities continue after project termination. PMID- 27693334 TI - Historical developments in children's deep brain stimulation. AB - BACKGROUND: Heterogeneous by the underlying pathobiology and clinical presentation, childhood onset dystonia is most frequently progressive, with related disability and limitations in functions of daily living. Consequently, there is an obvious need for efficient symptomatic therapies. METHODS AND RESULTS: Following lesional surgery to basal ganglia (BG) and thalamus, deep brain stimulation (DBS) is a more conservative and adjustable intervention to and validated for internal segment of the globus pallidus (GPi), highly efficient in treating isolated "primary" dystonia and associated symptoms such as subcortical myoclonus. The role of DBS in acquired, neurometabolic and degenerative disorders with dystonia deserves further exploration to confirm as an efficient and lasting therapy. However, the pathobiological background with distribution of the sequellae over the central nervous system and related clinical features, will limit DBS efficacy in these conditions. Cumulative arguments propose DBS in severe life threatening dystonic conditions called status dystonicus as first line therapy, irrespective of the underlying cause. There are no currently available validated selection criteria for DBS in pediatric dystonia. Concurrent targets such as subthalamic nucleus (STN) and several motor nuclei of the thalamus are under exploration and only little information is available in children. DBS programming in paediatric population was adopted from experience in adults. The choice of neuromodulatory DBS parameters could influence not only the initial therapeutic outcome of dystonic symptoms but also its maintenance over time and potentially the occurrence of DBS related side effects. CONCLUSION: DBS allows efficient symptomatic treatment of severe dystonia in children and advances pathophysiological knowledge about local and distributed abnormal neural activity over the motor cortical-subcortical networks in dystonia and other movement disorders. PMID- 27693335 TI - Investigation of the effects of vanilloids in chronic fatigue syndrome. AB - AIM OF THE STUDY: To assess the effectiveness of TRPV1 modulators in animal model of Chronic fatigue syndrome (CFS). To assess central and peripheral behavioral activity of TRPV1 modulators. MATERIAL AND METHODS: CFS was induced by forcing the rats to swim for 10min for 21 consecutive days. The rats were treated with capsaicin (TRPV1 agonist, 2.5mg/kg) and n-tert-butylcyclohexanol (TRPV1 antagonist, 10mg/kg) for 21days 30min before the exposure to stress procedure. The behavioral consequence of CFS was measured in terms of immobility time, grip strength, locomotor activity, and anxiety level using Rota rod, Actophotometer, and Elevated plus maze model respectively. The other parameters include Plasma corticosterone, adrenal gland and spleen weight, complete blood count, blood urea niterogen (BUN), Lactate dehydrogenase (LDH), Lipid peroxidation, catalase and reduced glutathione (GSH). RESULTS AND DISCUSSION: TRPV1 modulators reversed (p<0.05) the increase in immobility period, anxiety, spleen weight, BUN and LDH levels, and MDA levels along with decrease in grip strength, locomotor activity, plasma corticosterone, adrenal gland weight, catalase, and GSH. There was also significant increase in total WBC count when compared with the disease control group. The reversal was attributed to modulation of HPA axis, oxidative stress, anaerobic respiration product, muscle degradation product. CONCLUSION: The present study reveals the effectiveness of n-tert-butylcyclohexanol and capsaicin against chronic fatigue syndrome. The mechanism of action can be attributed to inhibition of TRPV1 channel and thereby modulating pain perception, neuroendocrine function, oxidative stress and immune function. PMID- 27693336 TI - Anti-aggregation property of thymoquinone induced by copper-nanoparticles: A biophysical approach. AB - Quaternary amine of diethylaminoethyl rosin ester (QRMAE), chemically synthesized by rosin modified biocompatible cationic surfactant, has various biological applications in the field of pharmacy as well as used as food product additive. Here, we report biophysical insights in to the interaction mechanism of thymoquinone (TQ), copper nanoparticles (Cu-NPs) and QRMAE with bovine serum albumin (BSA) individually and also in complexes forms to determine their competitive binding affinity. We have also studied the aggregation-inhibition effects of Cu-NPs and TQ individually, as well as in complexes form in the presence of QRMAE surfactant which is responsible for induction of amorphous aggregates in BSA within hours of incubation at 65 degrees C and physiological pH. The formation of aggregates was established by using various spectroscopic methods and dye binding assay. The circular dichroism (CD) spectroscopy showed that QRMAE significantly altered the secondary structure of BSA. However, the presence of TQ and Cu-NPs restricted the aggregation process which was observed to be more efficient when TQ and Cu-NPs were present together. This study provides very significant competitive binding results of QRMAE, Cu-NPs, TQ and protein aggregation behavior at higher temperature which was induced by rosin surfactant QRMAE, and protein aggregation process was inhibited by Cu-NPs, TQ individually and together. Therefore, our finding suggested that rosin surfactant QRMAE has high propensity to induce amorphous aggregation in BSA which was favored at elevated temperature and higher concentration of the protein. When BSA QRMAE sample was incubated in the presence Cu-NPs under similar condition, the aggregation propensity reduced, and drastically inhibited by TQ and Cu-NPs together. PMID- 27693337 TI - Immobilization of glucoamylase on triazine-functionalized Fe3O4/graphene oxide nanocomposite: Improved stability and reusability. AB - Immobilization of an enzyme can enhance its catalytic activity, depending on the properties of the enzyme and the matrix. Graphene oxide is a nontoxic material and selective modulator for enzyme activity and is also a thermostable molecule that is important in large-scale nanostructure sheet applications. Herein, we have successfully developed a strategy for preparing a nanocomposite for enzyme immobilization model with high loading capacity. Nanostructures of hybrid graphene oxide-Fe3O4-cyanuric chloride (GO/MNP-CC) have adjustable surface chemistry that is an excellent candidate for covalent immobilization of enzymes. The morphology, structure and properties of GO/MNP-CC nanocomposite were investigated through different analytical tools. Glucoamylase, an important enzyme in industrial food products, was immobilized on GO/MNP-CC and exhibited excellent catalytic activity at pH 6.5 and 60 degrees C. The results of this study indicated that the catalytic activity, reusability and stability of immobilized enzyme have been obviously improved compared to the free enzyme. The apparent Km and numax for free and immobilized glucoamylase were also determined. These properties make them a good candidate to improve the practicality and further the development of the capacity enzyme attachment. Thus, the synthesized matrix has the potential for practical applications in other and binary enzyme immobilization and would have a wide prospect for their applications in bio industry and biosensing. PMID- 27693338 TI - Targeted delivery of doxorubicin to breast cancer cells by magnetic LHRH chitosan bioconjugated nanoparticles. AB - The novel dual targeted nanoparticles loaded with doxorubicin (DOX) and magnetic nanoparticles (MNPs) were prepared for treatment of breast cancer. Nanoparticles were produced by a layer-by-layer technique and functionalized with a bioconjugate of chitosan-poly(methyl vinyl ether maleic acid)(PMVMA)-LHRH to target LHRH receptors. The successful production of chitosan-PMVMA copolymer and its conjugation to LHRH was confirmed by FTIR and 1HNMR spectroscopy. Capillary electrophoresis analysis showed 72.51% LHRH conjugation efficiency. Transmission electron microscopy and thermogravimetric analysis showed the entrapment of the MNPs in the core of the nanoparticles and vibrating sample magnetometery confirmed their paramagnetic properties. The iron content of nanoparticles determined by inductively coupled plasma optical emission spectrometry showed to be between 3.5-84%. Particle size, zeta potential, drug entrapment and release efficiency of the nanoparticles were 88.1-182.6nm, 10-30mV, 62.3-87.6% and 79.8 83.4%, respectively. No significant protein binding was seen by nanoparticles. The MTT assay showed in LHRH positive cells of MCF-7 the IC50 of the drug reduced to about 2 fold compared to the free drug. By saturation of LHRH receptors the viable MCF7 cells increased significantly after exposure with the targeted nanoparticles. Therefore, the cellular uptake of the nanoparticles might be done by active endocytosis through the LHRH receptors. PMID- 27693339 TI - Chitosan/Mimosa tenuiflora films as potential cellular patch for skin regeneration. AB - Bio-composites films were prepared by casting and drying of aqueous solutions containing different weight ratios of chitosan and bark of Mimosa tenuiflora. The physico-chemical and functional properties of the films were characterized by scanning electron microscopy, dynamical mechanical analysis, wettability, cytotoxicity and in vitro antibacterial activities. The morphology studies confirmed that the presence of Mimosa tenuiflora change the surface of films. Moreover, the incorporation of Mimosa tenuiflora improved the thermal stability of the films, as it was indicated by the changes in the glass temperatures obtained. Water-uptake ability changed in relation to polymeric composition of film. This property increased by the addition of Mimosa tenuiflora to the film. Improved antibacterial properties were measured against Escherichia Coli and Micrococcus lysodeikticus or luteus. Finally, cytotoxicity was studied by MTT assay and the films were non-toxic. These preliminary results provide a cheap way to prepare chitosan/Mimosa tenuiflora films for wound healing and skin regeneration. PMID- 27693340 TI - Effect of testosterone and its aliphatic and aromatic dimers on DNA morphology. AB - Conjugation of DNA with testosterone and it aliphatic dimer (alip) and aromatic dimer (arom) was investigated in aqueous solution at pH 7.4. Multiple spectroscopic methods, transmission electron microscopy (TEM) and molecular modeling were used to characterize steroid-DNA binding and DNA morphology. Spectroscopic analysis showed that testosterone binds DNA via A7, A16, A17, T8, T15 and T18 nucleobases with overall binding constants Ktest-DNA=1.8 (+/ 0.4)*104M-1, Ktest-dimeralip-DNA=5.7 (+/-0.7)*104M-1 and Ktest-dimer-arom-DNA=7.3 (+/-0.9)*104M-1. The binding affinity increases in this order: testosterone dimer aromatic>testosterone dimer-aliphatic>testosterone. The steroid loading efficacy was 40-50%. Transmission electron microscopy showed major changes in DNA morphology as testosterone-DNA interaction occurred with increase in the diameter of the DNA aggregate, indicating encapsulation of testosterone by DNA. Modeling showed the presence of several nucleobases attached to testosterone with the free binding energy of -4.93Kcal/mol. PMID- 27693341 TI - Differences in conformational stability of the two alpha domains of the disease associated and non-disease-associated subtypes of HLA-B27. AB - The MHC Class I molecule, HLA-B27, is strongly linked with development of the inflammatory arthritic disease, ankylosing spondylitis (AS); whereas the B*2705 subtype shows strong association, B*2709 is not associated with disease, even though the two subtypes differ in only a single residue at position 116. Currently, attention is focused on the misfolding propensities of these two subtypes, including studies of disulfide-linked dimers and non-covalently formed high molecular weight (HMW) aggregates. Using mutants retaining only a single cysteine at positions C67 or C164, and using a cysteine-reactive, environment sensitive, fluorescence probe (acrylodan), we find that within the same overall population of identical single-cysteine HLA-B27 molecules, there exist sub populations which (a) possess free cysteines which react with acrylodan, (b) form disulfide-linked dimers, and (c) form HMW aggregates. Further, using acrylodan fluorescence, we find (d) that the alpha1 and alpha2 domains unfold independently of each other in HMW aggregates, (e) that these two domains of B*2709 are less stable to chemical and thermal denaturation than the corresponding domains of B*2705, suggesting easier clearance of misfolded molecules in the former, and (f) C67 is much more exposed in B*2705 than in B*2709, which could potentially explain how B*2705 more easily forms C67-mediated disulfide-bonded dimers. PMID- 27693342 TI - A review on the pharmacological effects of vitexin and isovitexin. AB - Vitexin and isovitexin are active components of many traditional Chinese medicines, and were found in various medicinal plants. Vitexin (apigenin-8-C glucoside) has recently received increased attention due to its wide range of pharmacological effects, including but not limited to anti-oxidant, anti-cancer, anti-inflammatory, anti-hyperalgesic, and neuroprotective effects. Isovitexin (apigenin-6-C-glucoside), an isomer of vitexin, generally purified together with vitexin, also exhibits diverse biological activities. Latest research has suggested that vitexin and isovitexin could be potential substitute medicines for diversity diseases, and may be adjuvants for stubborn diseases or health products. This review summarized recent findings on various pharmacological activities and associative signalling pathways of vitexin and isovitexin to provide a reference for future research and clinical applications. PMID- 27693344 TI - Diverse relations between ABC transporters and lipids: An overview. AB - It was first discovered in 1992 that P-glycoprotein (Pgp, ABCB1), an ATP binding cassette (ABC) transporter, can transport phospholipids such as phosphatidylcholine, -ethanolamine and -serine as well as glucosylceramide and glycosphingolipids. Subsequently, many other ABC transporters were identified to act as lipid transporters. For substrate transport by ABC transporters, typically a classic, alternating access model with an ATP-dependent conformational switch between a high and a low affinity substrate binding site is evoked. Transport of small hydrophilic substrates can easily be imagined this way, as the molecule can in principle enter and exit the transporter in the same orientation. Lipids on the other hand need to undergo a 180 degrees degree turn as they translocate from one membrane leaflet to the other. Lipids and lipidated molecules are highly diverse, so there may be various ways how to achieve their flipping and flopping. Nonetheless, an increase in biophysical, biochemical and structural data is beginning to shed some light on specific aspects of lipid transport by ABC transporters. In addition, there is now abundant evidence that lipids affect ABC transporter conformation, dynamics as well as transport and ATPase activity in general. In this review, we will discuss different ways in which lipids and ABC transporters interact and how lipid translocation may be achieved with a focus on the techniques used to investigate these processes.

PMID- 27693343 TI - Neural mechanisms of human temporal fear conditioning. AB - Learning the temporal relationship between a warning cue (conditioned stimulus; CS) and aversive threat (unconditioned stimulus; UCS) is an important aspect of Pavlovian conditioning. Although prior functional magnetic resonance imaging (fMRI) research has identified brain regions that support Pavlovian conditioning, it remains unclear whether these regions support time-related processes important for this type of associative learning. Elucidating the neural substrates of temporal conditioning is important for a complete understanding of the Pavlovian conditioning process. Therefore, the present study used a temporal Pavlovian conditioning procedure to investigate brain activity that mediates the formation of temporal associations. During fMRI, twenty-three healthy volunteers completed a temporal conditioning procedure and a control task that does not support conditioning. Specifically, during the temporal conditioning procedure, the UCS was presented at fixed intervals (ITI: 20s) while in the control condition the UCS was presented at random intervals (Average ITI: 20s, ITI Range: 6-34s). We observed greater skin conductance responses and expectancy of the UCS during fixed (i.e., temporal conditioning) relative to random (i.e., control procedure) interval trials. These findings demonstrate fixed trials support temporal conditioning, while random trials do not. During fixed interval trials, greater conditioned fMRI signal responses were observed within dorsolateral prefrontal cortex, inferior parietal lobule, inferior and middle temporal cortex, hippocampus, and amygdala. The current findings suggest these brain regions constitute a neural circuit that encodes the temporal information necessary for Pavlovian fear conditioning. PMID- 27693345 TI - Biosurfactants and surfactants interacting with membranes and proteins: Same but different? AB - Biosurfactants (BS) are surface-active molecules produced by microorganisms. For several decades they have attracted interest as promising alternatives to current petroleum-based surfactants. Aside from their green profile, they have remarkably low critical micelle concentrations, reduce the air/water surface tension to very low levels and are excellent emulsifiers, all of which make them comparable or superior to their synthetic counterparts. These remarkable physical properties derive from their more complex chemical structures in which hydrophilic and hydrophobic regions are not as clearly separated as chemical surfactants but have a more mosaic distribution of polarity as well as branched or circular structures. This allows the lipopeptide surfactin to adopt spherical structures to facilitate dense packing at interfaces. They are also more complex. Glycolipid BS, e.g. rhamnolipids (RL) and sophorolipids, are produced biologically as mixtures which vary in the size and saturation of the hydrophobic region as well as modifications in the hydrophilic headgroup, such as the number of sugar groups and different levels of acetylation, leading to variable surface-active properties. Their amphiphilicity allows RL to insert easily into membranes at sub cmc concentrations to modulate membrane structure and extract lipopolysaccharides, leading to extensive biofilm remodeling in vivo, sometimes in collaboration with hydrophobic RL precursors. Thanks to their mosaicity, even anionic BS like RL only bind weakly to proteins and show much lower denaturing potency, even supporting membrane protein refolding. Nevertheless, they can promote protein degradation by proteases e.g. by neutralizing positive charges, which together with their biofilm-combating properties makes them very promising detergent surfactants.

PMID- 27693346 TI - A survey of herbal weeds for treating skin disorders from Southern Thailand: Songkhla and Krabi Province. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Skin diseases are common health problems which affecting to all ages. In Thailand, the number of patients diagnosed with skin diseases is increasing every year. Nowadays, The Ministry of Public Health is supporting and promoting herbs for treating various disorders, including disorders of the skin to reduce the problem of antibiotic resistance and adverse drug reactions. This study aimed to: (1) enumerate the herbal weeds for treating skin disorders; (2) study local knowledge of weed utilization for treating skin disorders according to the folk healers in Songkhla and Krabi province; and (3) study quantitative data by Informant consensus factor (ICF), Use value (UV) and Fidelity level (FL) value. MATERIALS AND METHODS: Field surveys and Semi structured interviews about the local names, parts of plants used, preparation and use method, as well as local properties were done. The data were further analyzed by descriptive statistics, interpretation and quantitative indexes (ICF, UV as well as FL). RESULTS: The results discovered 44 herbal species of weeds belonging to 41 genera in 25 families. The most used plant families were Amaranthaceae (6 species). Most plants were used to treat abscess (18 species; 40.91%). The highest UV was recorded for Commelina benghalensis (0.65). The highest ICF values were found in vitiligo, ringworm, tinea versicolor and burns (1.00 each). The highest FL values were recorded for Cleome gynandra, Cleome viscosa, Sphenoclea zeylanica, Acmella oleracea, Leersia hexandra, Cyperus involucratus, Phyllanthus urinaria and Iresine herbstii (100.00 each). A review of the literatures revealed that 34 plant species had already been tested for their pharmacological activities. The biological activities associated with treatment of skin diseases can be divided into four categories: antimicrobial, anti-inflammatory, wound healing and antioxidant activity. CONCLUSION: The information indicates that herbal weedy utilization is still importance to the treatment of traditional healers through accumulated experience for a long time. Therefore, this study is a guide to the conservation of folk medicinal knowledge. It might be implied as the basis for drug development and application of herbal weeds to treat skin disorders along with promoting sustainable use of natural resource.

PMID- 27693349 TI - The Plasmodium alveolin IMC1a is stabilised by its terminal cysteine motifs and facilitates sporozoite morphogenesis and infectivity in a dose-dependent manner. AB - Apicomplexan parasites possess a unique cortical cytoskeleton structure composed of intermediate filaments. Its building blocks are provided by a conserved family of proteins named alveolins. The core alveolin structure is made up of tandem repeat sequences, thought to be responsible for the filamentous properties of these proteins. A subset of alveolins also possess conserved motifs composed of three closely spaced cysteine residues situated near the ends of the polypeptides. The roles of these cysteine motifs and their contribution to alveolin function remains poorly understood. The sporozoite-expressed IMC1a is unique within the Plasmodium alveolin family in having conserved cysteine motifs at both termini. Using transgenic Plasmodium berghei parasites, we show in this structure-function analysis that mutagenesis of the amino- or carboxy-terminal cysteine motif causes marked reductions in IMC1a protein levels in the parasite, which are accompanied by partial losses of sporozoite shape and infectivity. Our findings give new insight into alveolin function, identifying a dose-dependent effect of alveolin depletion on sporozoite size and infectivity, and vital roles of the terminal cysteine motifs in maintaining alveolin stability in the parasite. PMID- 27693347 TI - Genome-Wide Association Study Identifies African-Specific Susceptibility Loci in African Americans With Inflammatory Bowel Disease. AB - BACKGROUND & AIMS: The inflammatory bowel diseases (IBD) ulcerative colitis (UC) and Crohn's disease (CD) cause significant morbidity and are increasing in prevalence among all populations, including African Americans. More than 200 susceptibility loci have been identified in populations of predominantly European ancestry, but few loci have been associated with IBD in other ethnicities. METHODS: We performed 2 high-density, genome-wide scans comprising 2345 cases of African Americans with IBD (1646 with CD, 583 with UC, and 116 inflammatory bowel disease unclassified) and 5002 individuals without IBD (controls, identified from the Health Retirement Study and Kaiser Permanente database). Single-nucleotide polymorphisms (SNPs) associated at P < 5.0 * 10-8 in meta-analysis with a nominal evidence (P < .05) in each scan were considered to have genome-wide significance. RESULTS: We detected SNPs at HLA-DRB1, and African-specific SNPs at ZNF649 and LSAMP, with associations of genome-wide significance for UC. We detected SNPs at USP25 with associations of genome-wide significance for IBD. No associations of genome-wide significance were detected for CD. In addition, 9 genes previously associated with IBD contained SNPs with significant evidence for replication (P < 1.6 * 10-6): ADCY3, CXCR6, HLA-DRB1 to HLA-DQA1 (genome-wide significance on conditioning), IL12B,PTGER4, and TNC for IBD; IL23R, PTGER4, and SNX20 (in strong linkage disequilibrium with NOD2) for CD; and KCNQ2 (near TNFRSF6B) for UC. Several of these genes, such as TNC (near TNFSF15), CXCR6, and genes associated with IBD at the HLA locus, contained SNPs with unique association patterns with African-specific alleles. CONCLUSIONS: We performed a genome-wide association study of African Americans with IBD and identified loci associated with UC in only this population; we also replicated IBD, CD, and UC loci identified in European populations. The detection of variants associated with IBD risk in only people of African descent demonstrates the importance of studying the genetics of IBD and other complex diseases in populations beyond those of European ancestry. PMID- 27693351 TI - Replication-Dependent Unhooking of DNA Interstrand Cross-Links by the NEIL3 Glycosylase. AB - During eukaryotic DNA interstrand cross-link (ICL) repair, cross-links are resolved ("unhooked") by nucleolytic incisions surrounding the lesion. In vertebrates, ICL repair is triggered when replication forks collide with the lesion, leading to FANCI-FANCD2-dependent unhooking and formation of a double strand break (DSB) intermediate. Using Xenopus egg extracts, we describe here a replication-coupled ICL repair pathway that does not require incisions or FANCI FANCD2. Instead, the ICL is unhooked when one of the two N-glycosyl bonds forming the cross-link is cleaved by the DNA glycosylase NEIL3. Cleavage by NEIL3 is the primary unhooking mechanism for psoralen and abasic site ICLs. When N-glycosyl bond cleavage is prevented, unhooking occurs via FANCI-FANCD2-dependent incisions. In summary, we identify an incision-independent unhooking mechanism that avoids DSB formation and represents the preferred pathway of ICL repair in a vertebrate cell-free system.

We report that loss of HVEM leads to cell-autonomous activation of B cell proliferation and drives the development of GC lymphomas in vivo. HVEM-deficient lymphoma B cells also induce a tumor-supportive microenvironment marked by exacerbated lymphoid stroma activation and increased recruitment of T follicular helper (TFH) cells. These changes result from the disruption of inhibitory cell-cell interactions between the HVEM and BTLA (B and T lymphocyte attenuator) receptors. Accordingly, administration of the HVEM ectodomain protein (solHVEM(P37-V202)) binds BTLA and restores tumor suppression. To deliver solHVEM to lymphomas in vivo, we engineered CD19-targeted chimeric antigen receptor (CAR) T cells that produce solHVEM locally and continuously. These modified CAR-T cells show enhanced therapeutic activity against xenografted lymphomas. Hence, the HVEM-BTLA axis opposes lymphoma development, and our study illustrates the use of CAR-T cells as "micro-pharmacies" able to deliver an anti cancer protein.

AB - Common sequence variants in cis-regulatory elements (CREs) are suspected etiological causes of complex disorders. We previously identified an intronic enhancer variant in the RET gene disrupting SOX10 binding and increasing Hirschsprung disease (HSCR) risk 4-fold. We now show that two other functionally independent CRE variants, one binding Gata2 and the other binding Rarb, also reduce Ret expression and increase risk 2- and 1.7-fold. By studying human and mouse fetal gut tissues and cell lines, we demonstrate that reduced RET expression propagates throughout its gene regulatory network, exerting effects on both its positive and negative feedback components. We also provide evidence that the presence of a combination of CRE variants synergistically reduces RET expression and its effects throughout the GRN. These studies show how the effects of functionally independent non-coding variants in a coordinated gene regulatory network amplify their individually small effects, providing a model for complex disorders. PMID- 27693353 TI - Engineering T Cells with Customized Therapeutic Response Programs Using Synthetic Notch Receptors. AB - Redirecting T cells to attack cancer using engineered chimeric receptors provides powerful new therapeutic capabilities. However, the effectiveness of therapeutic T cells is constrained by the endogenous T cell response: certain facets of natural response programs can be toxic, whereas other responses, such as the ability to overcome tumor immunosuppression, are absent. Thus, the efficacy and safety of therapeutic cells could be improved if we could custom sculpt immune cell responses. Synthetic Notch (synNotch) receptors induce transcriptional activation in response to recognition of user-specified antigens. We show that synNotch receptors can be used to sculpt custom response programs in primary T cells: they can drive a la carte cytokine secretion profiles, biased T cell differentiation, and local delivery of non-native therapeutic payloads, such as antibodies, in response to antigen. SynNotch T cells can thus be used as a general platform to recognize and remodel local microenvironments associated with diverse diseases. PMID- 27693354 TI - Functional Metabolomics Describes the Yeast Biosynthetic Regulome. AB - Genome-metabolism interactions enable cell growth. To probe the extent of these interactions and delineate their functional contributions, we quantified the Saccharomyces amino acid metabolome and its response to systematic gene deletion. Over one-third of coding genes, in particular those important for chromatin dynamics, translation, and transport, contribute to biosynthetic metabolism. Specific amino acid signatures characterize genes of similar function. This enabled us to exploit functional metabolomics to connect metabolic regulators to their effectors, as exemplified by TORC1, whose inhibition in exponentially growing cells is shown to match an interruption in endomembrane transport. Providing orthogonal information compared to physical and genetic interaction networks, metabolomic signatures cluster more than half of the so far uncharacterized yeast genes and provide functional annotation for them. A major part of coding genes is therefore participating in gene-metabolism interactions that expose the metabolism regulatory network and enable access to an underexplored space in gene function. PMID- 27693355 TI - Intrinsically Disordered Proteins Drive Emergence and Inheritance of Biological Traits. AB - Prions are a paradigm-shifting mechanism of inheritance in which phenotypes are encoded by self-templating protein conformations rather than nucleic acids. Here, we examine the breadth of protein-based inheritance across the yeast proteome by assessing the ability of nearly every open reading frame (ORF; ~5,300 ORFs) to induce heritable traits. Transient overexpression of nearly 50 proteins created traits that remained heritable long after their expression returned to normal. These traits were beneficial, had prion-like patterns of inheritance, were common in wild yeasts, and could be transmitted to naive cells with protein alone. Most inducing proteins were not known prions and did not form amyloid. Instead, they are highly enriched in nucleic acid binding proteins with large intrinsically disordered domains that have been widely conserved across evolution. Thus, our data establish a common type of protein-based inheritance through which intrinsically disordered proteins can drive the emergence of new traits and adaptive opportunities. PMID- 27693356 TI - IRGB10 Liberates Bacterial Ligands for Sensing by the AIM2 and Caspase-11-NLRP3 Inflammasomes. AB - The inflammasome is an intracellular signaling complex, which on recognition of pathogens and physiological aberration, drives activation of caspase-1, pyroptosis, and the release of the pro-inflammatory cytokines IL-1beta and IL-18. Bacterial ligands must secure entry into the cytoplasm to activate inflammasomes; however, the mechanisms by which concealed ligands are liberated in the cytoplasm have remained unclear. Here, we showed that the interferon-inducible protein IRGB10 is essential for activation of the DNA-sensing AIM2 inflammasome by Francisella novicida and contributed to the activation of the LPS-sensing caspase 11 and NLRP3 inflammasome by Gram-negative bacteria. IRGB10 directly targeted cytoplasmic bacteria through a mechanism requiring guanylate-binding proteins. Localization of IRGB10 to the bacterial cell membrane compromised bacterial structural integrity and mediated cytosolic release of ligands for recognition by inflammasome sensors. Overall, our results reveal IRGB10 as part of a conserved signaling hub at the interface between cell-autonomous immunity and innate immune sensing pathways. PMID- 27693357 TI - Zika Virus: Immunity and Vaccine Development. AB - The emergence of Zika virus in the Americas and Caribbean created an urgent need for vaccines to reduce transmission and prevent disease, particularly the devastating neurodevelopmental defects that occur in utero. Rapid advances in Zika immunity and the development of vaccine candidates provide cautious optimism that preventive measures are possible. PMID- 27693359 TI - Crystal Structure of Silkworm PIWI-Clade Argonaute Siwi Bound to piRNA. AB - PIWI-clade Argonaute proteins associate with PIWI-interacting RNAs (piRNAs) and silence transposable elements in animal gonads. Here, we report the crystal structure of a silkworm PIWI-clade Argonaute, Siwi, bound to the endogenous piRNA, at 2.4 A resolution. Siwi adopts a bilobed architecture consisting of N PAZ and MID-PIWI lobes, in which the 5' and 3' ends of the bound piRNA are anchored by the MID-PIWI and PAZ domains, respectively. A structural comparison of Siwi with AGO-clade Argonautes reveals notable differences in their nucleic acid-binding channels, likely reflecting the distinct lengths of their guide RNAs and their mechanistic differences in guide RNA loading and cleavage product release. In addition, the structure reveals that Siwi and prokaryotic, but not eukaryotic, AGO-clade Argonautes share unexpected similarities, such as metal dependent 5'-phosphate recognition and a potential structural transition during the catalytic-tetrad formation. Overall, this study provides a critical starting point toward a mechanistic understanding of piRNA-mediated transposon silencing. PMID- 27693360 TI - Eimeria spp. infecting quenda (Isoodon obesulus) in the greater Perth region, Western Australia. AB - Parasites of wildlife inhabiting urbanised and peri-urban environments are of interest regarding wildlife population health, and also veterinary public health in the case of parasites that can also infect humans and domestic animals. This study aimed to: identify, and estimate the prevalence of, species of Eimeria parasitic in quenda (Isoodon obesulus) in the greater Perth region, Western Australia; 2) morphologically describe and genetically characterise a novel observed species of Eimeria as E. angustus; and 3) genetically characterise E. kanyana. Eimeria spp. prevalence was 76.1% (95% CI 64.9-84.5%), and four putative species of Eimeria were identified. Eimeria kanyana was identified infecting quenda for the first time, with a prevalence of 54.9% (43.4-66.0%). Eimeria quenda was less prevalent, at 7.0% (3.1-15.5%). The novel species E. angustus was present in 45.1% of sampled quenda (34.0-56.6%). A second novel morphotype of Eimeria was present in 2.8% of sampled quenda (0.9-9.7%). Mixed Eimeria spp. infections were present in 21/71 quenda (29.6%, 95% CI 20.2-41.1%). Molecular phylogenetic analyses of E. kanyana and E. angustus were conducted at the 18S rRNA and mitochondrial cytochrome oxidase loci. At both loci, two isolates identified as E. kanyana grouped in a phylogenetic clade with E. trichosuri. Five isolates identified as the novel E. angustus were most closely related to E. tropidura at the 18S locus. At the COI locus, no sequence data were available for E. tropidura; isolates of E. angustus grouped with E. sciurorum. PMID- 27693358 TI - Mitochondrial Protein Synthesis Adapts to Influx of Nuclear-Encoded Protein. AB - Mitochondrial ribosomes translate membrane integral core subunits of the oxidative phosphorylation system encoded by mtDNA. These translation products associate with nuclear-encoded, imported proteins to form enzyme complexes that produce ATP. Here, we show that human mitochondrial ribosomes display translational plasticity to cope with the supply of imported nuclear-encoded subunits. Ribosomes expressing mitochondrial-encoded COX1 mRNA selectively engage with cytochrome c oxidase assembly factors in the inner membrane. Assembly defects of the cytochrome c oxidase arrest mitochondrial translation in a ribosome nascent chain complex with a partially membrane-inserted COX1 translation product. This complex represents a primed state of the translation product that can be retrieved for assembly. These findings establish a mammalian translational plasticity pathway in mitochondria that enables adaptation of mitochondrial protein synthesis to the influx of nuclear-encoded subunits. PMID- 27693361 TI - A nanotechnology based new approach for Trypanosoma evansi chemotherapy: In vitro and vivo trypanocidal effect of (-)-alpha-bisabolol. AB - The aim of this study was to evaluate the in vitro and in vivo susceptibility of Trypanosoma evansi to alpha-Bisabolol and solid lipid nanoparticles containing alpha-Bisabolol (SLN-B). In vitro, a trypanocidal effect of alpha-Bisabolol and SLN-B was observed when used at 0.5, 1 and 2% concentrations, i.e., the concentrations of 1 and 2% showed a faster trypanocidal effect when compared to chemotherapy (diminazene aceturate - D.A.). T. evansi infected mice were treated with alpha-Bisabolol and SLN-B at a dose of 1.0 mL kg-1 during seven days via oral gavage. In vivo, treatment with SLN-B, D.A. and D.A. associated with SLN-B were able to increase (p < 0.05) the pre-patent period and longevity when compared to positive control (infected and untreated animals), but showed no curative efficacy. T. evansi infected mice treated with D.A. associate with SLN B, where a curative efficacy of 50% was found, a much better result when D. A and SLN-B were used alone (16.66%). In summary, the association with D. A + SLN-B can be used as an alternative to improve the therapeutic effectiveness of D.A., and for treatment of infected animals with T. evansi. Also, the nanotechnology associated with natural products arises an important alternative for the improve the trypanocidal action. PMID- 27693362 TI - Over-the-scope clip for endoscopic closure of gastrogastric fistulae. AB - BACKGROUND: Gastrogastric fistulae (GGF) are a well-known complication of Roux-en Y gastric bypass (RYGB). Endoscopic approaches for closure of GGF have gained popularity, but with limited data and efficacy. OBJECTIVES: The primary arm of the study was to evaluate the safety and efficacy of the endoscopic closure of GGF using the over-the-scope clip (OTSC) device. SETTING: University hospital, United States METHODS: This is a retrospective review of consecutive patients at a single academic center from September 2013 to December 2014 who underwent upper endoscopy with attempted OTSC placement for closure of GGF related to RYGB. Preprocedural, procedural, and postprocedural data were collected. Outcome measures included technical success, primary success, and long-term success. RESULTS: A total of 14 patients underwent attempted GGF closure using OTSC. Twelve of the 14 patients (85.7%) had technical success. Four patients were lost to follow-up. Primary success was achieved in 5 of the 10 patients (50%) in which it was assessed, either by upper gastrointestinal series or endoscopy. One of the 5 patients who had primary success was then lost to follow-up. Of the 4 patients in whom primary success was achieved and had long-term follow up, 75% (n = 3) achieved long-term success at a mean follow-up of 6.6 months from initial OTSC placement (range, 3-9), making for a long-term success rate of 33% (3/9). There were no reported complications. CONCLUSION: OTSC closure of small GGF is feasible, safe, and offers a reasonable alternative to surgical revision. Large GGF may undergo attempted endoscopic closure, acknowledging a high failure rate. PMID- 27693363 TI - 3D pharmacophore-based virtual screening, docking and density functional theory approach towards the discovery of novel human epidermal growth factor receptor-2 (HER2) inhibitors. AB - Human epidermal growth factor receptor 2 (HER2) is one of the four members of the epidermal growth factor receptor (EGFR) family and is expressed to facilitate cellular proliferation across various tissue types. Therapies targeting HER2, which is a transmembrane glycoprotein with tyrosine kinase activity, offer promising prospects especially in breast and gastric/gastroesophageal cancer patients. Persistence of both primary and acquired resistance to various routine drugs/antibodies is a disappointing outcome in the treatment of many HER2 positive cancer patients and is a challenge that requires formulation of new and improved strategies to overcome the same. Identification of novel HER2 inhibitors with improved therapeutics index was performed with a highly correlating (r=0.975) ligand-based pharmacophore model (Hypo1) in this study. Hypo1 was generated from a training set of 22 compounds with HER2 inhibitory activity and this well-validated hypothesis was subsequently used as a 3D query to screen compounds in a total of four databases of which two were natural product databases. Further, these compounds were analyzed for compliance with Veber's drug-likeness rule and optimum ADMET parameters. The selected compounds were then subjected to molecular docking and Density Functional Theory (DFT) analysis to discern their molecular interactions at the active site of HER2. The findings thus presented would be an important starting point towards the development of novel HER2 inhibitors using well-validated computational techniques. PMID- 27693364 TI - Viral infections of oceanic plankton blooms. AB - Viruses are known to impact blooms of phytoplankton in the ocean, in some cases causing the bloom to crash. Here, using a population model that includes viral infection, we investigate the conditions under which the presence of a virus significantly impacts the population dynamics. A major focus is how spatial variability influences the spread of an epidemic in a stirring and mixing field. The combination of viral infection and diffusion can cause waves of the epidemic to sweep through the domain, with the epidemic lasting much longer than in the homogeneous case. Stirring by the fluid flow can greatly increase this effect causing an increase in the fraction of the bloom that is affected and in certain circumstances (high diffusion and stirring) can totally suppress the bloom. The fluid environment affects the relative spatial structure of the components of the system. High values of the concentrations of the virus and infected phytoplankton are found in thin filaments along fronts of uninfected (susceptible) phytoplankton. PMID- 27693365 TI - Hydra effects in discrete-time models of stable communities. AB - A species exhibits a hydra effect when, counter-intuitively, increased mortality of the species causes an increase in its abundance. Hydra effects have been studied in many continuous time (differential equation) multispecies models, but only rarely have hydra effects been observed in or studied with discrete time (difference equation) multispecies models. In addition most discrete time theory focuses on single-species models. Thus, it is unclear what unifying characteristics determine when hydra effects arise in discrete time models. Here, using discrete time multispecies models (where total abundance is the single variable describing each population), I show that a species exhibits a hydra effect in a stable system only when fixing that species' density at its equilibrium density destabilizes the system. This general characteristic is referred to as subsystem instability. I apply this result to two-species models and identify specific mechanisms that cause hydra effects in stable communities, e.g., in host--parasitoid models, host Allee effects and saturating parasitoid functional responses can cause parasitoid hydra effects. I discuss how the general characteristic can be used to identify mechanisms causing hydra effects in communities with three or more species. I also show that the condition for hydra effects at stable equilibria implies the system is reactive (i.e., density perturbations can grow before ultimately declining). This study extends previous work on conditions for hydra effects in single-species models by identifying necessary conditions for stable systems and sufficient conditions for cyclic systems. In total, these results show that hydra effects can arise in many more communities than previously appreciated and that hydra effects were present, but unrecognized, in previously studied discrete time models. PMID- 27693366 TI - Exploring optimal control strategies in seasonally varying flu-like epidemics. AB - The impact of optimal control strategies in the context of seasonally varying infectious disease transmission remains a wide open research area. We investigate optimal control strategies for flu-like epidemics using an SIR (susceptible infectious-recovered) type epidemic model where the transmission rate varies seasonally Specifically, we explore optimal control strategies using time dependent treatment and vaccination as control functions alone or in combination. Optimal strategies and associated epidemic outcomes are contrasted for epidemics with constant and seasonal transmission rates. Our results show that the epidemic outcomes assessed in terms of the timing and size of seasonal epidemics subject to optimal control strategies are highly sensitive to various parameters including R0, the timing of the introduction of the initial number of infectious individuals into the population, the time at which interventions start, and the strength of the seasonal forcing that modulates the time-dependent transmission rate. Findings highlight the difficult challenge in predicting short-term epidemic impact in the context of seasonally varying infectious disease transmission with some interventions scenarios exhibiting larger epidemic size compared to scenarios without control interventions. PMID- 27693367 TI - The immune system of the gut and potential adverse effects of oral nanocarriers on its function. AB - There is substantial effort in modern pharmacotherapy to use nanoparticle-based drug delivery systems (nDDS) for improving the oral absorption of drugs. An often neglected circumstance regarding this approach is that the gut is a major part of the immune system that may be vulnerable for immune-cell toxicity, or mediate humoral immune response against various components of nDDS, recognized as foreign. This review recapitulates the structure and function of gut-associated lymphoid tissue (GALT), i.e., the enteral section of mucosa-associated lymphoid tissue (MALT) and reminds how virus-like nDDS may potentially induce immunogenicity just as attenuated or killed viruses do in oral vaccines. Furthermore, we present examples for immune toxicities of emulsifiers and polymer containing micelles, manifested in complement activation-related pseudoallergy (CARPA). A major message of the review is that early testing of immunogenicity or other adverse immune effects of nDDS in appropriate test systems or models may be prudent to recognize the risk of rare immune problems that may surface in late stage clinical trials or after marketing of nDDS. PMID- 27693368 TI - The Relationship Between Resistant Tachycardia and Treatment for GERD. AB - : The use of medications that block gastric acid secretion, such as proton pump inhibitors, has rapidly escalated in the United States. Although originally intended for short-term treatment of specific conditions, PPIs have expanded to long-term use with unanticipated consequences, including mineral deficiencies related to lack of sufficient stomach acid needed for extraction of minerals from the foods and supplements ingested. Herein, the author reports on a case of a patient with tachycardia and other arrhythmias that had been resistant to the medications prescribed by a series of cardiologists. The patient had been on PPI for several years preceding his arrhythmias, prescribed for stress-related gastritis. The author did comprehensive blood work and discovered that the patient was deficient in many of the minerals tested, including magnesium, known to be essential for normal cardiac function. After the patient slowly weaned himself off the PPIs and took magnesium and other minerals, the tachycardia resolved without any medication. CONCLUSIONS: This case demonstrates the importance of carefully reviewing the list of medications patients are taking and having a thorough understanding of the possible long-term risks associated with those medications. The patient's presenting symptoms have the potential to be related-directly or indirectly-to the medications that have been prescribed. PMID- 27693370 TI - CASZ1 loss-of-function mutation associated with congenital heart disease. AB - As the most common form of birth defect in humans, congenital heart disease (CHD) is associated with substantial morbidity and mortality in both children and adults. Increasing evidence demonstrates that genetic defects play a pivotal role in the pathogenesis of CHD. However, CHD is of great heterogeneity, and in an overwhelming majority of cases, the genetic determinants underpinning CHD remain elusive. In the present investigation, the coding exons and flanking introns of the CASZ1 gene, which codes for a zinc finger transcription factor essential for the cardiovascular morphogenesis, were sequenced in 172 unrelated patients with CHD. As a result, a novel heterozygous CASZ1 mutation, p.L38P, was identified in an index patient with congenital ventricular septal defect (VSD). Genetic scanning of the mutation carrier's available family members revealed that the mutation was present in all affected patients but absent in unaffected individuals. Analysis of the proband's pedigree showed that the mutation co segregated with VSD, which was transmitted as an autosomal dominant trait with complete penetrance. The missense mutation, which altered the amino acid that was highly conserved evolutionarily, was absent in 200 unrelated, ethnically-matched healthy subjects used as controls. Functional deciphers by using a dual luciferase reporter assay system unveiled that the mutant CASZ1 had significantly reduced transcriptional activity as compared with its wild-type counterpart. To the best of our knowledge, the current study firstly identifies CASZ1 as a new gene predisposing to CHD in humans, which provides novel insight into the molecular mechanisms underlying CHD and a potential therapeutic target for CASZ1 associated CHD, suggesting potential implications for personalized prophylaxis and therapy of CHD. PMID- 27693371 TI - JAK/STAT signaling pathway-mediated immune response in silkworm (Bombyx mori) challenged by Beauveria bassiana. AB - Innate immunity was critical in insects defensive system and able to be induced by Janus kinase/signal transducer and activator of transcription cascade transduction (JAK/STAT) signaling pathway. Currently, it had been identified many JAK/STAT signaling pathway-related genes in silkworm, but little function was known on insect innate immunity. To explore the roles of JAK/STAT pathway in antifungal immune response in silkworm (Bombyx mori) against Beauveria bassiana infection, the expression patterns of B. mori C-type lectin 5 (BmCTL5) and genes encoding 6 components of JAK/STAT signaling pathway in silkworm challenged by B. bassiana were analyzed using quantitative real time PCR. Meanwhile the activation of JAK/STAT signaling pathway by various pathogenic micro-organisms and the affect of JAK/STAT signaling pathway inhibitors on antifungal activity in silkworm hemolymph was also detected. Moreover, RNAi assay of BmCTL5 and the affect on expression levels of signaling factors were also analyzed. We found that JAK/STAT pathway could be obviously activated in silkworm challenged with B. bassiana and had no response to bacteria and B. mori cytoplasmic polyhedrosis virus (BmCPV). However, the temporal expression patterns of JAK/STAT signaling pathway related genes were significantly different. B. mori downstream receptor kinase (BmDRK) might be a positive regulator of JAK/STAT signaling pathway in silkworm against B. bassiana infection. Moreover, antifungal activity assay showed that the suppression of JAK/STAT signaling pathway by inhibitors could significantly inhibit the antifungal activity in hemolymph and resulted in increased sensitivity of silkworm to B. bassiana infection, indicating that JAK/STAT signaling pathway might be involved in the synthesis and secretion of antifungal substances. The results of RNAi assays suggested that BmCTL5 might be one pattern recognition receptors for JAK/STAT signaling pathway in silkworm. These findings yield insights for better understand the molecular mechanisms of JAK/STAT signaling pathway in antifungal immune response in silkworm. PMID- 27693369 TI - Embryonic origin and lineage hierarchies of the neural progenitor subtypes building the zebrafish adult midbrain. AB - Neurogenesis in the post-embryonic vertebrate brain varies in extent and efficiency between species and brain territories. Distinct neurogenesis modes may account for this diversity, and several neural progenitor subtypes, radial glial cells (RG) and neuroepithelial progenitors (NE), have been identified in the adult zebrafish brain. The neurogenic sequences issued from these progenitors, and their contribution to brain construction, remain incompletely understood. Here we use genetic tracing techniques based on conditional Cre recombination and Tet-On neuronal birthdating to unravel the neurogenic sequence operating from NE progenitors in the zebrafish post-embryonic optic tectum. We reveal that a subpopulation of her5-positive NE cells of the posterior midbrain layer stands at the top of a neurogenic hierarchy involving, in order, the amplification pool of the tectal proliferation zone (TPZ), followed by her4-positive RG cells with transient neurogenic activity. We further demonstrate that the adult her5 positive NE pool is issued in lineage from an identically located NE pool expressing the same gene in the embryonic neural tube. Finally, we show that these features are reminiscent of the neurogenic sequence and embryonic origin of the her9-positive progenitor NE pool involved in the construction of the lateral pallium at post-embryonic stages. Together, our results highlight the shared recruitment of an identical neurogenic strategy by two remote brain territories, where long-lasting NE pools serve both as a growth zone and as the life-long source of young neurogenic RG cells. PMID- 27693372 TI - Characterization and comparative profiling of the small RNA transcriptomes in the Hemipteran insect Nilaparvata lugens. AB - MicroRNAs (miRNAs) are a group of small RNAs involved in various biological processes through negative regulation of mRNAs at the post-transcriptional level. The brown planthopper (BPH), Nilaparvata lugens (Stal), is one of the most serious and destructive insect pests of rice. In the present study, two small RNA libraries of virulent N. lugens populations (Biotype I survives on susceptive rice variety TN1 and Biotype Y survives on moderately resistant rice variety YHY15) were constructed and sequenced using the high-throughput sequencing technology in order to identify the relationship between miRNAs of N.lugens and adaptation of BPH pests to rice resistance. In total 15,758,632 and 11,442,592 reads, corresponding to 3,144,026 and 2,550,049 unique sequences, were obtained in the two libraries (BPH-TN1 and BPH-YHY15 libraries), respectively. A total of 41 potential novel miRNAs were predicted in the two libraries, and 26 miRNAs showed significantly differential expression between two libraries. All miRNAs were significantly up-regulated in the BPH-TN1 library. Target genes likely regulated by these differentially expressed miRNAs were predicted using computational prediction. The functional annotation of target genes performed by Gene Ontology enrichment (GO) and Kyoto Encyclopedia of Genes and Genomes pathway analysis (KEGG) indicated that a majority of differential miRNAs were involved in "Metabolism" pathway. These results provided an understanding of the role of miRNAs in BPH to adaptability of BPH on rice resistance, and will be useful in developing new control strategies for host defense against BPH.

PMID- 27693375 TI - Patient perceptions of clinical care in complementary medicine: A systematic review of the consultation experience. AB - OBJECTIVE: This review aims to describe the prevalence of empathy, empowerment and patient-centred clinical care experienced by patients in complementary medicine (CM) consultations. METHODS: A systematic review was undertaken of original research exploring patient perceptions of CM clinical care. Ten databases were searched: Alt HealthWatch, AMED, CINAHL Plus, MEDLINE Complete, Cochrane Library, PubMed, Proquest Medical Collection, PsycInfo, Social Sciences Citation Index and Psychology Collection. Studies were included which reported patient perceptions of consultation with CM practitioners and were excluded where experimental methods controlled the nature of consultation processes. RESULTS: Findings of included studies (n=34) were categorised under the a priori themes of empathy, empowerment and patient-centred care. This produced a substantial pool of qualitative data detailing patient-reported experiences which consistently confirmed occurrence of these themes in CM consultation. Quantitative data was correlative, yet was insufficient to definitively describe prevalence of such experiences. CONCLUSION: While it is evident that CM consultations provide a patient experience of empathy, empowerment and patient-centredness, further research is warranted to quantify this experience before it can be defined as characteristic of CM clinical care. PRACTICE IMPLICATIONS: This review draws attention to the potential role of CM as a resource for patients' psychosocial health needs. PMID- 27693373 TI - Ruthenium-Clotrimazole complex has significant efficacy in the murine model of cutaneous leishmaniasis. AB - In previous studies we reported a novel series of organometallic compounds, RuII complexed with clotrimazole, displaying potent trypanosomatid activity with unnoticeable toxicity toward normal mammalian cells. In view of the promising activity of Ru-clotrimazole complexes against Leishmania major (L. major), the present work sought to investigate the anti-leishmanial activity of the AM162 complex in the murine model of cutaneous leishmaniasis. In addition, to facilitate the design of new therapeutic strategies against this disease, we investigated the mode of action of two Ru-clotrimazole complexes in L. major promastigotes. Overall, we demonstrate that AM162 significantly reduced the lesion size in mice exposed to L. major infection. In addition, Ru-clotrimazole compounds are able to induce a mitochondrial dependent apoptotic-like death in the extracellular form of the parasite based on labeling of DNA fragments, mitochondrial depolarization, cell cycle alteration profile and plasma membrane phospholipid externalization. Our findings reveal a promising efficacy of the Ru clotrimazole AM162 complex for the treatment of cutaneous leishmaniasis, as well as pro-apoptotic activity and thus guarantees further evaluation in pre-clinical studies. PMID- 27693376 TI - Morphogenesis and proliferative rule of porcine transmissible gastroenteritis virus in porcine intestinal epithelial cells. AB - To gain a better understanding of the replication, proliferation and infection characteristics of porcine transmissible gastroenteritis virus (TGEV) in porcine intestinal epithelial cells (IECs), this study established a cell model of IECs infected with the Chongqing (CQ) strain of TGEV. The morphogenesis and proliferative rule of TGEV in porcine IECs were investigated using transmission electron microscopy, indirect immunofluorescence assays and real-time fluorescence quantitative PCR. Observations under the TEM indicated that the enveloped viral particles were roughly spherical, with diameters of between 80 and 120nm. The virions entered porcine IECs by membrane fusion and the mature viruses in the vacuoles were transported to the cell membrane before release. The results also showed that from 0 to 12h after TGEV infection of porcine IECs, the intracellular viral RNA content did not change significantly. Logarithmic growth occurred from 12 to 36h, after which it gradually decreased. Moreover, the extracellular RNA content began to rise at 24h after inoculation and then reduced gradually at approximately 48h. This study provided a theoretical foundation for further study on the infection characteristics of TGEV in target cells. PMID- 27693379 TI - Ferriheme catalyzes nitric oxide reaction with glutathione to form S nitrosoglutathione: A novel mechanism for formation of S-nitrosothiols. AB - S-nitrosothiols (SNO) perform many important functions in biological systems, but the mechanism by which they are generated in vivo remains a contentious issue. Nitric oxide (NO) reacts with thiols to form SNO only in the presence of a molecule that will accept an electron from either NO or the thiol. In this study, we present evidence that ferriheme accepts an electron from NO or glutathione (GSH) to generate S-nitrosoglutathione (GSNO) in vitro under anaerobic or hypoxic (2% O2) conditions. Ferriheme formed charge transfer-stable complexes with NO to form ferriheme-NO (heme-Fe(II)-NO+) and with GSH to form ferriheme-GS (heme Fe(II)-GS*) under anaerobic conditions. The reaction between GSH and the heme Fe(II)-NO+ complex or between NO and the heme-Fe(II)-GS* complex resulted in simultaneous reductive ferriheme nitrosylation (heme-Fe(II)NO) and the generation of GSNO. Thus, ferriheme is readily reduced to ferroheme in the presence of NO and GSH together, but not with either individually. The reaction between NO and the heme-Fe(II)-GS* complex to generate GSNO occurred more rapidly than NO was consumed by endothelial cells, but not red blood cells. In addition, pretreatment of endothelial cells with ferriheme or the ferriheme-GS complex generated SNO upon addition of NO under hypoxic conditions. The results of this study raise the possibility that in vivo, ferriheme can complex with GSH to form ferriheme-GS complex (heme-Fe(II)-GS*), which rapidly reacts with NO to generate GSNO under intracellular oxygen levels. The GSNO formation by this mechanism is more efficient than any other in vitro mechanism(s) reported so far.

AB - Fibroblast growth factor 21 (FGF21) is the first known endocrine signal activated by protein restriction. Although FGF21 is robustly elevated in low-protein environments, increased FGF21 is also seen in various other contexts such as fasting, overfeeding, ketogenic diets, and high-carbohydrate diets, leaving its nutritional context and physiological role unresolved and controversial. Here, we use the Geometric Framework, a nutritional modeling platform, to help reconcile these apparently conflicting findings in mice confined to one of 25 diets that varied in protein, carbohydrate, and fat content. We show that FGF21 was elevated under low protein intakes and maximally when low protein was coupled with high carbohydrate intakes. Our results explain how elevation of FGF21 occurs both under starvation and hyperphagia, and show that the metabolic outcomes associated with elevated FGF21 depend on the nutritional context, differing according to whether the animal is in a state of under- or overfeeding.

AB - Oxidative damage and aggregation of cellular proteins is a hallmark of neuronal cell death after neurotrauma and chronic neurodegenerative conditions. Autophagy and ubiquitin protease system are involved in degradation of protein aggregates, and interruption of their function is linked to apoptotic cell death in these diseases. Oxidative modification of cysteine groups in key molecular proteins has been linked to modification of cellular systems and cell death in these conditions. Glutathione and thioredoxin systems provide reducing protons that can effectively reverse protein modifications and promote cell survival. The central role of Thioredoxin in inhibition of apoptosis is well identified. Additionally, its involvement in initiation of autophagy has been suggested recently. We therefore aimed to investigate the involvement of Thioredoxin system in autophagy apoptosis processes. A model of serum deprivation in SH-SY5Y was used that is associated with autophagy and apoptosis. Using pharmacological and RNA-editing technology we show that Thioredoxin reductase deficiency in this model enhances oxidative stress and interrupts the early protective autophagy and promotes apoptosis. This was associated with decreased protein-degradation in lysosomes due to altered lysosomal acidification and accumulation of autophagosomes as well as impairment in proteasome pathway. We further confirmed that the extent of oxidative stress is a determining factor in autophagy- apoptosis interplay, as upregulation of cellular reducing capacity by N-acetylcysteine prevented impairment in autophagy and proteasome systems thus promoted cell viability. Our study provides evidence that excessive oxidative stress inhibits protein degradation systems and affects the final stages of autophagy by inhibiting autolysosome maturation: a novel mechanistic link between protein aggregation and conversion of autophagy to apoptosis that can be applicable to neurodegenerative diseases. PMID- 27693378 TI - Tissue Immunometabolism: Development, Physiology, and Pathobiology. AB - Evolution of metazoans resulted in the specialization of cellular and tissue function. This was accomplished by division of labor, which allowed tissue parenchymal cells to prioritize their core functions while ancillary functions were delegated to tissue accessory cells, such as immune, stromal, and endothelial cells. In metabolic organs, the accessory cells communicate with their clients, the tissue parenchymal cells, to optimize cellular processes, allowing organisms to adapt to changes in their environment. Here, we discuss tissue immunometabolism from this vantage point and use examples from adipose tissues (white, beige, and brown) and liver to outline the general principles by which accessory cells support metabolic homeostasis in parenchymal cells. A corollary of this model is that disruption of communication between client and accessory cells might predispose metabolic organs to the development of disease. PMID- 27693382 TI - Effects of physical exercise on myokines expression and brown adipose-like phenotype modulation in rats fed a high-fat diet. AB - AIMS: Exercise-stimulated myokine secretion into circulation may be related with browning in white adipose tissue (WAT), representing a positive metabolic effect on whole-body fat mass. However, limited information is yet available regarding the impact of exercise on myokine-related modulation of adipocyte phenotype in WAT from obese rats. MAIN METHODS: Sprague-Dawley rats (n=60) were divided into sedentary and voluntary physical activity (VPA) groups and fed with standard (35kcal% fat) or high-fat (HFD, 71kcal% fat)-isoenergetic diets. The VPA-groups had unrestricted access to wheel running throughout the protocol. After-9weeks, half of sedentary standard (SS) and sedentary HFD (HS)-fed animals were exercised on treadmill (endurance training, ET) for 8-weeks while maintaining the dietary treatments. KEY FINDINGS: The adipocyte hypertrophy induced by HFD were attenuated by VPA and ET. HFD decreased 5' AMP-activated protein kinase (AMPK) activity in muscle as well as peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1alpha) and uncoupling protein 1 (UCP1) proteins in eWAT, while not affecting circulating irisin. VPA increased eWAT Tmem26 mRNA levels in the standard diet-fed group, whereas ET increased AMPK, interleukin 6 (IL-6) and fibronectin type III domain-containing protein 5 (FNDC5) protein expression in muscle, but had no impact on circulating irisin protein content. In eWAT, ET increased bone morphogenetic protein 7 (Bmp7), Cidea and PGC-1alpha in both diet fed animals, whereas BMP7, Prdm16, UCP1 and FNDC5 only in standard diet-fed group. SIGNIFICANCE: Data suggest that ET-induced myokine production seems to contribute, at least in part, to the "brown-like" phenotype in WAT from rats fed a HFD. PMID- 27693381 TI - Disrupted mitochondrial genes and inflammation following stroke. AB - AIMS: Determine the subacute time course of mitochondria disruption, cell death, and inflammation in a rat model of unilateral motor cortical ischemic stroke. MAIN METHODS: Rats received unilateral ischemia of the motor cortex and were tested on behavioral tasks to determine impairments. Animals were euthanized at 24h, 72h and 144h and mRNA expression of key mitochondria proteins and indicators of inflammation, apoptosis and potential regenerative processes in ipsilesion cortex and striatum, using RT-qPCR. Mitochondrial proteins were examined at 144h using immunoblot analysis. KEY FINDINGS: Rats with stroke induced-behavioral deficits had sustained, 144h post-lesion, decreases in mitochondrial-encoded electron transport chain proteins NADH dehydrogenase subunit-1 and cytochrome c oxidase subunit-1 (mRNA and protein) and mitochondrial DNA content in perilesion motor and sensory cortex. Uncoupling-protein-2 gene expression, but not superoxide dismutase-2, remained elevated in ipsilateral cortex and striatum at this time. Cortical inflammatory cytokine, interleukin-6, was increased early and was followed by increased macrophage marker F4/80 after stroke. Cleaved caspase-3 activation was elevated in cortex and growth associated protein-43 was elevated in the cortex and striatum six days post-lesion. SIGNIFICANCE: We identified a relationship between three disrupted pathways, (1) sustained loss of mitochondrial proteins and mitochondrial DNA copy number in the cortex linked to decreased mitochondrial gene transcription; (2) early inflammatory response mediated by interleukin- 6 followed by macrophages; (3) apoptosis in conjunction with the activation of regenerative pathways. The stroke-induced spatial and temporal profiles lay the foundation to target pharmacological therapeutics to these three pathways. PMID- 27693383 TI - Intranasal insulin improves cerebral blood flow, Nrf-2 expression and BDNF in STZ (ICV)-induced memory impaired rats. AB - AIMS: Insulin/insulin receptor signaling is involved in cognitive functions. Clinical studies have shown that intranasal insulin administration improves memory functions. However, the molecular mechanisms associated with improvement in memory functions are largely unexplored. Therefore, we investigated the protective effect of intranasal insulin in intracerebroventricular (ICV) streptozotocin (STZ) induced memory impairment in rats. MAIN METHODS: Rats were injected with STZ (3mg/kg, ICV) bilaterally twice, on days 1 and 3 and intranasal insulin (2IU/rat/day) was given for 14days. Memory was assessed by Morris water maze test. Cerebral blood flow (CBF) was measured by laser-Doppler flowmetry. The biochemical and molecular studies were done in cortex and hippocampus of rat brain. KEY FINDINGS: STZ (ICV) administration caused memory impairment along with the reduction of CBF, ATP level, and Nrf-2 expression. Treatment with intranasal insulin significantly improved memory functions as well as restored CBF, ATP content and Nrf-2 expression in STZ injected rats. STZ administration stimulated oxidative-nitrosative stress as evidenced by a significant increase in ROS, malondialdehyde, NO level and inducible nitric oxide synthase expression and the decrease in glutathione level; which was normalized by intranasal insulin delivery. STZ-induced cholinergic dysfunction (AChE activity and alpha7-nAChR expression), and mitochondrial hypofunction was largely prevented by treatment with intranasal insulin. Intranasal insulin delivery successfully restored BDNF level and pCREB expression in STZ injected rats. SIGNIFICANCE: The study shows the beneficial effects of intranasal insulin against STZ-induced memory impairment, which attributed to improved CBF, cholinergic function, brain energy metabolism, BDNF, Nrf-2 expression and antioxidative action. PMID- 27693384 TI - A novel inhibitor of BCL2, Disarib abrogates tumor growth while sparing platelets, by activating intrinsic pathway of apoptosis. AB - Antiapoptotic protein BCL2, serves as an excellent target for anticancer therapy owing to its increased level in cancers. Previously, we have described characterization of a novel BCL2 inhibitor, Disarib, which showed selective cytotoxicity in BCL2 'high' cancer cells and CLL patient cells. Here, we have investigated the mechanism of Disarib-induced cytotoxicity, and compared its efficacy with a well-established BCL2 inhibitor, ABT199. We show that Disarib administration caused tumor regression in mouse allograft and xenograft models, exhibited platelet sparing property and did not exhibit significant side effects. Importantly, comparison between Disarib and ABT199, revealed higher efficacy for Disarib in mouse tumor model and cancer cell lines. Disarib induced cell death by activating intrinsic apoptotic pathway. Interestingly, Disarib showed synergism with paclitaxel, suggesting its potential for combination therapy. Thus, we provide mechanistic insights into the cell death pathways induced by Disarib, report that Disarib exhibited better effect than currently used ABT199 and demonstrate its combinatorial potential with paclitaxel. PMID- 27693385 TI - Proinflammatory signals are insufficient to drive definitive hematopoietic specification of human HSCs in vitro. AB - Recent studies in zebrafish and mice have revealed that proinflammatory signaling is a positive regulator of definitive hematopoietic development. Whether proinflammatory signaling also regulates human hematopoietic specification remains unknown. Here, we explored the impact of the proinflammatory cytokines tumor necrosis factor-alpha (TNFalpha), interferon-gamma (IFNgamma), and interleukin-1beta (IL1beta) on in vitro hematopoietic differentiation using human pluripotent stem cells. Gene expression analysis and enzyme-linked immunosorbent assay revealed the absence of a proinflammatory signature during hematopoietic development of human pluripotent stem cells. Functionally, the emergence of hemogenic endothelial progenitors (CD31+CD34+CD45- or CD34+CD43-CD73-) and hematopoietic cells (CD43+CD45+) was not affected by treatment with increasing doses of TNFalpha, IFNgamma, and IL1beta irrespective of the developmental window or the differentiation protocol used (embryoid body or OP9 co-culture based). Similarly, knockdown of endogenous NF-kB signaling had no impact on hematopoietic differentiation of human pluripotent stem cells. This study serves as a demonstration that TNFalpha, IFNgamma, and IL1beta signals do not improve hematopoietic differentiation of human pluripotent stem cells using current protocols and suggests that proinflammatory signaling is insufficient to drive definitive hematopoietic specification of human hematopoietic stem cells in vitro. PMID- 27693387 TI - Alterations in the bone marrow microenvironment may elicit defective hematopoiesis: a comparison of aplastic anemia, chronic myeloid leukemia, and normal bone marrow. AB - Hematopoiesis involves complex interactions between hematopoietic cells and the bone marrow (BM) microenvironment. The specific causes and mechanisms underlying dysregulated hematopoiesis are unknown. Here, BM biopsy specimens from patients with aplastic anemia (AA) and chronic myeloid leukemia (CML) and normal marrow were analyzed by semiquantitative immunohistochemistry to determine changes in the hematopoietic stem cell (HSC) compartment and BM microenvironment. HSC levels were lowest in AA and highest in CML. T and B lymphocytes were decreased in AA (p < 0.01) and CML (p < 0.01). Natural killer cells were observed in AA, but were absent in CML and healthy controls (p < 0.01). Macrophages and mast cells were absent in CML. There were significant differences between AA and CML stromal cell components. No nestin+ cells were observed in CML and the mean number of stromal cell-derived factor-1-positive cells was lowest in CML. Osteopontin+ cells were higher in AA than in CML (p < 0.01); osteonectin+ cells were higher in CML than in AA (p < 0.01). There was no significant difference in the expression of osteocalcin between AA and CML. The number of endothelial cells was highest in CML and lowest in AA (p < 0.01). Our findings suggest that changes in BM microenvironment components might be related to defective hematopoiesis leading to AA and/or CML. PMID- 27693386 TI - Dynamic variation of CD5 surface expression levels within individual chronic lymphocytic leukemia clones. AB - Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of clonally derived mature CD5high B cells; however, the cellular origin of CLL is still unknown. Patients with CLL also harbor variable numbers of CD5low B cells, but the clonal relationship of these cells to the bulk disease is unknown and can have important implications for monitoring, treating, and understanding the biology of CLL. Here, we use B-cell receptors (BCRs) as molecular barcodes to first show by single-cell BCR sequencing that the great majority of CD5low B cells in the blood of CLL patients are clonally related to CD5high CLL B cells. We investigate whether CD5 state switching was likely to occur continuously as a common event or as a rare event in CLL by tracking somatic BCR mutations in bulk CLL B cells and using them to reconstruct the phylogenetic relationships and evolutionary history of the CLL in four patients. Using statistical methods, we show that there is no parsimonious route from a single or low number of CD5low switch events to the CD5high population, but rather, large-scale and/or dynamic switching between these CD5 states is the most likely explanation. The overlapping BCR repertoires between CD5high and CD5low cells from CLL patient peripheral blood reveal that CLL exists in a continuum of CD5 expression. The major proportion of CD5low B cells in patients are leukemic, thus identifying CD5low B cells as an important component of CLL, with implications for CLL pathogenesis, clinical monitoring, and the development of anti-CD5-directed therapies. PMID- 27693388 TI - Clinical-grade regulatory T cells: Comparative analysis of large-scale expansion conditions. AB - Recent clinical trials have indicated the high potential of regulatory T cells (Tregs) in the prevention of acute and chronic graft-versus-host disease (GvHD) after hematopoietic stem cell transplantation, but immune interventions require large numbers of Tregs. With respect to their limited natural occurrence, development and optimization of protocols for large-scale expansion of clinical grade Tregs are essential if considered for therapeutic use. We compared different clinical-grade large-scale expansion protocols for repetitive transfer of large numbers of Tregs in clinical trials for the prevention of acute and/or chronic GvHD. Donor Tregs were isolated using magnetic-activated cell sorting (MACS) technology with good manufacturing practice-compliant devices. CD8 and CD19 depletion followed by CD25 enrichment resulted in the isolation of CD4+CD25+CD127- Tregs with a mean purity of 77%. Cell populations were expanded ex vivo using X-Vivo 15 (+/-rapamycin), TexMACS (+/-rapamycin), and CellGro DC (+/-rapamycin) in the presence of interleukin-2. The highest rates of expansion of clinical-grade Tregs were observed for X-Vivo 15 and CellGro DC without rapamycin in compared with all other expansion media tested. The suppressive capacity of the expanded Treg population was maintained under all conditions investigated. Our data suggest that expansion with CellGro provides data comparable to those obtained with TexMACS or X-Vivo 15 with rapamycin, although all three conditions did not provide the same propagation rate as X-Vivo 15 alone. With respect to functionality, phenotype, and stability, CellGro DC medium represents a reasonable alternative for good manufacturing practice-compatible large-scale ex vivo expansion. PMID- 27693389 TI - Enzyme-linked immunosorbent assay for S100A9 in the stool of rats with dextran sulfate sodium-induced colitis. AB - Calprotectin, a heterodimer of S100A8 and S100A9, has been reported to be a useful biomarker in inflammatory bowel disease (IBD); however, the relationship between the fecal level of S100A9 and the extent of inflammation in IBD remains unclear. Our aim was to develop a new enzyme-linked immunosorbent assay (ELISA) for rat S100A9, and to investigate whether changes in fecal S100A9 levels reflect the inflammatory conditions in the intestinal tracts of rats with dextran sulfate sodium (DSS)-induced colitis. Anti-rat S100A9 monoclonal antibodies were raised in mice and used for the development of a novel ELISA for rat S100A9. The performance of our ELISA was assessed by dilution and recovery tests, and the detection range was 3.75-240ng/mL. The dilution test showed good linearity. The recovery of fecal S100A9 was 95.1% (mean), with a range of 86.1%-108.8%. Colitis was induced in rats by oral administration of 3% DSS/drinking water (DW) for 11days (D group), while DW alone was provided to rats of the control group (C group) during the same period. The extent of inflammation was evaluated with the disease activity index (DAI), and the concentration of fecal S100A9 was determined by ELISA. Both the DAI scores and the fecal S100A9 levels were significantly higher in the D group than in the C group. Microscopic observation revealed that S100A9 was dominantly produced in many immune cells of myeloid origin in rat rectal tissues. These results indicate that the novel ELISA may be applied to clinically evaluate IBD in rats with high sensitivity. In conclusion, our ELISA is useful in toxicological and pharmacological evaluations. PMID- 27693390 TI - Effect of heavy-intensity 'priming' exercise on oxygen uptake and muscle deoxygenation kinetics during moderate-intensity step-transitions initiated from an elevated work rate. AB - We examined the effect of heavy-intensity 'priming' exercise on the rate of adjustment of pulmonary O2 uptake (tauVO2p) initiated from elevated intensities. Fourteen men (separated into two groups: tauVO2p<=25s [Fast] or tauVO2p>25s [Slow]) completed step-transitions from 20W to 45% lactate threshold (LT; lower step, LS) and 45% to 90%LT (upper-step, US) performed (i) without; and (ii) with US preceded by heavy-intensity exercise (HUS). Breath-by-breath VO2p and near infrared spectroscopy-derived muscle deoxygenation ([HHb+Mb]) were measured. Compared to LS, tauVO2p was greater (p<0.05) in US in both Fast (LS, 19+/-4s; US, 30+/-4s) and Slow (LS, 25+/-5s; US, 40+/-11s) with tauVO2p in US being lower (p<0.05) in Fast. In HUS, tauVO2p in Slow was reduced (28+/-8s, p<0.05) and was not different (p>0.05) from LS or Fast group US. In Slow, tau[HHb+Mb] increased (p<0.05) in US relative to HUS; this finding coupled with a reduced tauVO2p indicates a priming-induced improvement in matching of muscle O2 delivery-to-O2 utilization during transitions from elevated intensities in those with Slow but not Fast VO2p kinetics. PMID- 27693392 TI - Transgenerational impairment of hippocampal Akt-mTOR signaling and behavioral deficits in the offspring of mice that experience postpartum depression-like illness. AB - Postpartum depression (PPD) has adverse effects on offspring and increases their vulnerability to psychiatric disorders such as depression. Akt-mTOR signaling in the hippocampus is implicated in depression but its role in the behavioral deficits in PPD offspring remains unknown. By using a prepregnancy stress model of PPD in which Balb/c females that experience chronic stress before pregnancy show long-lasting PPD-like behaviors, we tested depression-like behaviors in PPD offspring (PPD-F1) at juvenile and adult ages as well as in the second generation (PPD-F2) produced by cross of male PPD-F1 with naive females. Hippocampal Akt mTOR signaling was examined in the F1 and F2 generations of PPD, as well as in PPD-F1 mice treated with a single dose of the antidepressant ketamine. PPD-F1 showed depression-like behaviors at juvenile and adult stages, evidenced by reduced sucrose preference (SP), increased immobility time in the forced swim test (FST), and a longer latency to feed and reduced food consumption in the novelty suppressed feeding (NSF) test. PPD-F1 mice showed Akt-mTOR signaling deficiency in the hippocampus, with down-regulated expression of p-Akt, p-mTOR and p-p70S6K. A single dose of ketamine reversed the behavior deficits and the impairment in Akt-mTOR signaling in PPD-F1. Furthermore, the PPD-F2 mice remained deficient in the SP and NSF test and hippocampal Akt-mTOR signaling, although the performance in FST was normal. The present study demonstrated both long-term and transgenerational effects of PPD on the depression-like behaviors of offspring, and suggested impaired Akt-mTOR signaling may play a part. PMID- 27693391 TI - Replacement of serum with ocular fluid for cryopreservation of immature testes. AB - Cryopreservation of immature testis is a feasible approach for germplasm preservation of male animals. Combinations of dimethyl sulfoxide (DMSO) and foetal bovine serum (FBS) are used for testis cryopreservation. However, an alternative to FBS is needed, because FBS is expensive. Buffalo ocular fluid (BuOF), a slaughter house by-product, could be an economical option. The objective of the present study was to assess whether BuOF can replace FBS for cryopreservation of immature mouse (Mus musculus), rat (Rattus norvegicus), and buffalo (Bubalus bubalis) testes. Results showed that rodent and buffalo testes frozen in DMSO (10% for rodents and 20% for buffalo) with 20% FBS or BuOF had similar numbers of viable and DNA-damaged cells (P > 0.05). The expression of cell proliferation- (PCNA) and apoptosis-specific proteins (Annexin V and BAX/BCL2 ratio) were also comparable in mouse and buffalo testes frozen in DMSO with FBS or BuOF (P > 0.05). Interestingly, rat testis frozen in DMSO with BuOF had lower expression of Annexin V protein than testis frozen in DMSO with FBS (P < 0.05). The percentage of meiotic germ cells (pachytene-stage spermatocytes) in xenografts from testis frozen either in DMSO with BuOF or FBS did not significantly differ in rats or buffalo (P > 0.05). These findings provide evidence that BuOF has potential to replace FBS for cryopreservation of immature rodent and buffalo testis. Further investigation is needed to explore whether BuOF can replace FBS for testis cryopreservation of other species. PMID- 27693393 TI - Effect of exercise, exercise withdrawal, and continued regular exercise on excitability and long-term potentiation in the dentate gyrus of hippocampus. AB - Exercise mediates beneficial effects on the brain function and neural health, particularly in the hippocampus as the main area of memory. The hippocampus is a structure involved in exercise, which can improve synaptic plasticity and long term potentiation (LTP). The present study investigated the effect of exercise, exercise withdrawal, and continued regular exercise on excitability and long-term potentiation in the dentate gyrus (DG) of hippocampus. Fifty male Wistar rats were randomly allocated to the five control, sham, exercise, exercise withdrawal, and continued regular exercise treatments. The experimental animals were forced to run on a treadmill one hour a day at a speed of 20-21m/min over the two experimental periods of 21 and 42 days. While stimulating the medial perforant pathway, input-output (I/O) functions and LTP were recorded from the DG to evaluate synaptic potency and plasticity. The relevant responses in the DG were evaluated in all the groups from the slope and PS amplitude of the fEPSP. Results showed that the 21-day exercise treatment increased both the responsiveness and LTP in the DG of hippocampus. A 21-day withdrawal period after the exercise impaired the beneficial effects of the exercise, indicating the reversibility of these exercise-related hippocampal changes. Significant enhancements were also observed in cell responsiveness and LTP with the continued regular exercise (42 day) treatment. PMID- 27693394 TI - Central mechanism of the cardiovascular responses caused by L-proline microinjected into the paraventricular nucleus of the hypothalamus in unanesthetized rats. AB - Previously, we reported that microinjection of L-proline (L-Pro) into the paraventricular nucleus of the hypothalamus (PVN) caused vasopressin-mediated pressor responses in unanesthetized rats. In the present study, we report on the central mechanisms involved in the mediation of the cardiovascular effects caused by the microinjection of L-Pro into the PVN. Microinjection of increasing doses of L-Pro (3-100nmol/100nL) into the PVN caused dose-related pressor and bradycardic responses. No cardiovascular responses were observed after the microinjection of equimolar doses (33nmol/100nL) of its isomer D-Proline (D-Pro) or Mannitol. The PVN pretreatment with either a selective non-NMDA (NBQX) or selective NMDA (LY235959 or DL-AP7) glutamate receptor antagonists blocked the cardiovascular response to L-Pro (33nmol/100nL). The dose-effect curve for the pretreatment with increasing doses of LY235959 was located at the left in relation to the curves for NBQX and DL-AP7, showing that LY235959 is more potent than NBQX, which is more potent than DL-AP7 in inhibiting the cardiovascular response to L-Pro. The cardiovascular response to the microinjection of L-Pro into the PVN was not affected by local pretreatment with Nomega-Propyl-l-arginine (N-Propyl), a selective inhibitor of the neuronal nitric oxide synthase (nNOS), suggesting that NO does not mediate the responses to L-Pro in the PVN. In conclusion, the results suggest that ionotropic receptors in the PVN, blocked by both NMDA and non-NMDA receptor antagonists, mediate the pressor response to L Pro that results from activation of PVN vasopressinergic magnocellular neurons and vasopressin release into the systemic circulation. PMID- 27693395 TI - MiR-195 dependent roles of mitofusin2 in the mitochondrial dysfunction of hippocampal neurons in SAMP8 mice. AB - Abnormal gene expression, including mRNAs, and microRNAs (miRNA), have been identified in the development of Alzheimer's disease (AD). Although mitofusin2 (mfn2) has been found to be down-regulated in the neurons from hippocampus and cortex in AD patients, little is known about its roles and the regulatory mechanisms in the pathogenesis of AD. This study was performed to investigate the roles of mfn2 protein and its upstream regulatory mechanism in the progression of AD using a senescence accelerated mouse prone-8 (SAMP8) model. The results of quantitative real-time PCR and western blot revealed that mfn2 expression displayed a consistent decrease with aging in the hippocampus of SAMP8 than did age-matched SAMR1 mice. The luciferase activity assay combined with mutational analysis confirmed the binding site of miR-195 to the 3' -untranslated region (3' UTR) of mfn2 mRNA. Furthermore, miR-195 inhibitor or antigomir induced the higher level expression of mfn2 protein in vitro and in vivo. In addition, exogenous expression of miR-195 decreased the mitochondrial membrane potential (MMP) of the HT-22 cells by targeting mfn2. In conclusion, these results indicated that deregulation of mfn2 might be involved in mitochondrial dysfunction during the progression of AD, and its decreased expression was regulated at least in part by miR-195 in AD mice. The abnormal expression of miR-195 played a potential role in mitochondrial disorder by targeting mfn2 in hippocampus of SAMP8 mice. Therefore, upregulation of mfn2 protein by inhibiting miR-195 might be a potential new therapeutic strategy for treatment of AD. PMID- 27693398 TI - Cell fate regulation by chromatin ADP-ribosylation. AB - ADP-ribosylation is an evolutionarily conserved complex posttranslational modification that alters protein function and/or interaction. Intracellularly, it is mainly catalyzed by diphtheria toxin-like ADP-ribosyltransferases (ARTDs), which attach one or several ADP-ribose residues onto target proteins. Several specific mono- and poly-ADP-ribosylation binding modules exist; hydrolases reverse the modification. The best-characterized ARTD family member, ARTD1, regulates various DNA-associated processes. Here, we focus on the role of ARTD1 mediated chromatin ADP-ribosylation in development, differentiation, and pluripotency, and the recent development of new methodologies that will enable more insight into these processes. PMID- 27693396 TI - Functional connectivity patterns of normal human swallowing: difference among various viscosity swallows in normal and chin-tuck head positions. AB - Consuming thicker fluids and swallowing in the chin-tuck position has been shown to be advantageous for some patients with neurogenic dysphagia who aspirate due to various causes. The anatomical changes caused by these therapeutic techniques are well known, but it is unclear whether these changes alter the cerebral processing of swallow-related sensorimotor activity. We sought to investigate the effect of increased fluid viscosity and chin-down posture during swallowing on brain networks. 55 healthy adults performed water, nectar-thick, and honey thick liquid swallows in the neutral and chin-tuck positions while EEG signals were recorded. After pre-processing of the EEG timeseries, the time-frequency based synchrony measure was used for forming the brain networks to investigate whether there were differences among the brain networks between the swallowing of different fluid viscosities and swallowing in different head positions. We also investigated whether swallowing under various conditions exhibit small-world properties. Results showed that fluid viscosity affects the brain network in the Delta, Theta, Alpha, Beta, and Gamma frequency bands and that swallowing in the chin-tuck head position affects brain networks in the Alpha, Beta, and Gamma frequency bands. In addition, we showed that swallowing in all tested conditions exhibited small-world properties. Therefore, fluid viscosity and head positions should be considered in future swallowing EEG investigations. PMID- 27693397 TI - Selective CRF2 receptor agonists ameliorate the anxiety- and depression-like state developed during chronic nicotine treatment and consequent acute withdrawal in mice. AB - The aim of the present study was to investigate the effects of the selective agonists of the corticotropin-releasing factor (CRF) 2 receptor, urocortin 2 (UCN 2) and urocortin 3 (UCN 3), on the anxiety- and depression-like signs induced by acute nicotine withdrawal in mice. In order to do so, male CFLP mice were exposed for 7 days to repeated intraperitoneal (IP) injection with nicotine or saline solution and 1day of acute withdrawal and then a single intracerebroventricular (ICV) injection with UCN 2, UCN 3 or saline solution. After 30min the mice were observed in an elevated plus-maze test or a forced swim test, for anxiety- and depression-like behavior. After 5min of testing, the plasma corticosterone concentration reflecting the activity of the hypothalamic-pituitary-adrenal (HPA) axis was also determined by a chemo-fluorescent method. Half of the animals were treated ICV and evaluated on the 8th day, the other half on the 9th day. On the 8th day, nicotine-treated mice presented signs of anxiolysis and depression, but no significant elevation of the plasma corticosterone concentration. On the 9th day, nicotine-treated mice exhibited signs of anxiety and depression and a significant increase of the plasma corticosterone levels. Central administration of UCN 2 or UCN 3 ameliorated the anxiety- and depression-like state including the hyperactivity of the HPA axis, developed during acute withdrawal following chronic nicotine treatment. The present study suggests that selective CRF2 receptor agonists could be used as a therapy in nicotine addiction.

PMID- 27693400 TI - Spatial and temporal heterogeneity of infectious hematopoietic necrosis virus in Pacific Northwest salmonids. AB - The aquatic rhaboviral pathogen infectious hematopoietic necrosis virus (IHNV) causes acute disease in juvenile fish of a number of populations of Pacific salmonid species. Heavily managed in both marine and freshwater environments, these fish species are cultured during the juvenile stage in freshwater conservation hatcheries, where IHNV is one of the top three infectious diseases that cause serious morbidity and mortality. Therefore, a comprehensive study of viral genetic surveillance data representing 2590 field isolates collected between 1958 and 2014 was conducted to determine the spatial and temporal patterns of IHNV in the Pacific Northwest of the contiguous United States. Prevalence of infection varied over time, fluctuating over a rough 5-7yearcycle. The genetic analysis revealed numerous subgroups of IHNV, each of which exhibited spatial heterogeneity. Within all subgroups, dominant genetic types were apparent, though the temporal patterns of emergence of these types varied among subgroups. Finally, the affinity or fidelity of subgroups to specific host species also varied, where UC subgroup viruses exhibited a more generalist profile and all other subgroups exhibited a specialist profile. These complex patterns are likely synergistically driven by numerous ecological, pathobiological, and anthropogenic factors. Since only a few anthropogenic factors are candidates for managed intervention aimed at improving the health of threatened or endangered salmonid fish populations, determining the relative impact of these factors is a high priority for future studies.

AB - Macrophages are crucial player in the defense against multiple intracellular pathogens. Mycobacterium tuberculosis, the causative agent of tuberculosis which inflicted around one third of global population, can replicate and persist within macrophages. MicroRNAs, endogenous, small noncoding RNA, can regulate the expression of macrophages genes required for appropriate signaling. Mycobacteria can manipulate the expression of macrophages microRNAs to subvert cell response for its survival and persistence. This review summarized the progress of microRNAs in mycobacterial pathogenesis. PMID- 27693401 TI - Microgeographically diverse Plasmodium vivax populations at the Thai-Myanmar border. AB - Malaria transmission along international borders of the Greater Mekong Subregion is a big challenge for regional malaria elimination. At the Thai-Myanmar border, Plasmodium falciparum cases have dropped dramatically; however, increasing P. vivax prevalence and the emerging reports on hidden malaria burden due to asymptomatic infections demand attention. We conducted cross-sectional surveys to detect asymptomatic malaria infections in a small village located at Thai-Myanmar border and genotyped P. vivax infections in order to understand the level of genetic diversity on such a microgeographic scale. PCR/RFLP and DNA sequencing identified high levels of genetic polymorphisms at both Pvmsp3alpha and Pvmsp3beta loci among P. vivax infections. Combining the PCR/RFLP patterns of Pvmsp3alpha and Pvmsp3beta, a total of 10 genotypes were observed among 17 samples, while concatenated DNA sequences of Pvmsp3alpha and 3beta generated 14 haplotypes with haplotype diversity of 0.97. These markedly diverse parasites on a microgeographic scale suggest the circulation of a considerably large parasite population at the international border. PMID- 27693404 TI - Therapeutic Effect of Virtual Reality on Post-Stroke Patients: Randomized Clinical Trial. AB - OBJECTIVES: The study aimed to check the therapeutic effect of virtual reality associated with conventional physiotherapy on gait balance and the occurrence of falls after a stroke. METHODS: This was a randomized, blinded clinical trial conducted with post-stroke patients, randomized into two groups-treatment group and control group-and subjected to balance assessments by the Dynamic Gait Index and investigation of falls before and after 20 intervention sessions. Statistically significant difference was considered at P < .05. RESULTS: We selected 30 patients, but there were three segment losses, resulting in a total of 13 patients in the control group and 14 in the treatment group. There was an improvement in gait balance and reduced occurrence of falls in both groups. After intervention, the differences in gait balance in the control group (P = .047) and the reduction in the occurrence of falls in the treatment group (P = .049) were significant. However, in intergroup analysis, there was no difference in the two outcomes. CONCLUSIONS: Therapy with games was a useful tool for gait balance rehabilitation in post-stroke patients, with repercussions on the reduction of falls.

AB - BACKGROUND: The purpose of our study is to explore the relationship between recovery of neural function and transformation of the internal capsule (IC) after transient middle cerebral artery occlusion (MCAO) by using diffusion kurtosis imaging (DKI). METHODS: Six male adult Sprague-Dawley rats implemented with transient MCAO were used in this study. Sensorimotor function was assessed according to repetitive behavioral testing on day 1, 3, 7, 14, and 28 after cerebral ischemia. Metrics of DKI were acquired, and the time course of the region-to-normal ratio was evaluated in IC. RESULTS: After cerebral ischemia, relative fractional anisotropy in IC decreased on day 3 (P < .01). Relative mean diffusivity (rMD) increased on day 28 (P < .05). Relative mean diffusional kurtosis (rMK) increased on day 3 (P < .01) and decreased on day 7 (P < .05). Relative axial diffusional kurtosis (rKa) increased on day 3 (P < .01) and declined on day 7 (P < .05). Relative radial diffusional kurtosis (rKr) was reduced on day 7 (P < .05). Changes in rMK were larger than changes in rMD on day 3 (P < .05). The factor of rKa and rKr revealed marked difference on day 7 (P < .05) and day 14 (P < .05). Neurological function score showed that rats exhibited functional recovery from day 7 (P < .01) post stroke. CONCLUSIONS: This longitudinal multiparametric magnetic resonance imaging study suggested that K metrics offers information complimentary to conventional diffusion metrics and revealed the procedure during the structural modification in the ipsilateral IC following focal cerebral ischemia. After transient MCAO, the neural transformation occurred in a time-dependent procedure. PMID- 27693405 TI - The role of post-translational protein modifications on heart and vascular metabolism. PMID- 27693406 TI - Reveal the molecular signatures of hepatocellular carcinoma with different sizes by iTRAQ based quantitative proteomics. AB - : Tumor size of hepatocellular carcinoma (HCC) is a key parameter for predicting prognosis of HCC patients. The biological behaviors of HCC, such as tumor growth, recurrence and metastasis are significantly associated with tumor size. However, the underlying molecular mechanisms remain unclear. Here, we applied iTRAQ-based proteomic strategy to analyze the proteome differences among small, media, large and huge primary HCC tissues. In brief,88 proteins in small HCC, 69 proteins in media HCC, 118 proteins in large HCC and 215 proteins in huge HCC, were identified by comparing the proteome of cancerous tissues with its corresponding non-cancerous tissues. Further analysis of dysregulated proteins involved in signaling revealed that alteration of ERK1/2 and AKT signaling played important roles in the tumorigenesis or tumor growth in all subtypes. Interestingly, alteration of specific signaling was discovered in small and huge HCC, which might reflect specific molecular mechanisms of tumor growth. Furthermore, the dysregulation degree of a group of proteins has been confirmed to be significantly correlated with the tumor size; these proteins might be potential targets for studying tumor growth of HCC. Overall, we have revealed the molecular signatures of HCC with different tumor sizes, and provided fundamental information for further in-depth study. BIOLOGICAL SIGNIFICANCE: In this study, we compared the protein expression profiles among different HCC subtypes, including small HCC, media HCC, large HCC and huge HCC for the first time. The results clearly proved that different molecular alterations and specific signaling pathways were indeed involved in different HCC subtypes, which might explain the different malignancy biological behaviors. In addition, the dysregulation degree of a group of proteins has been confirmed to be significantly correlated with the tumor size. We believe that these findings would help us better understand the underlying molecular mechanisms of the tumorigenesis and development of HCC. PMID- 27693407 TI - The pUltra plasmid series: A robust and flexible tool for fluorescent labeling of Enterobacteria. AB - Fluorescent labeling has been an invaluable tool for the study of living organisms and bacterial species are no exception to this. Here we present and characterize the pUltra plasmids which express constitutively a fluorescent protein gene (GFP, RFP, YFP or CFP) from a strong synthetic promoter and are suitable for the fluorescent labeling of a broad range of Enterobacteria. The amount of expressed fluorophore from these genetic constructs is such, that the contours of the cells can be delineated on the basis of the fluorescent signal only. In addition, labeling through the pUltra plasmids can be used successfully for fluorescence and confocal microscopy while unambiguous distinction of cells labeled with different colors can be carried out efficiently by microscopy or flow cytometry. We compare the labeling provided by the pUltra plasmids with that of another plasmid series encoding fluorescent proteins and we show that the pUltra constructs are vastly superior in signal intensity and discrimination power without having any detectable growth rate effects for the bacterial population. We also use the pUltra plasmids to produce mixtures of differentially labeled pathogenic Escherichia, Shigella and Salmonella species which we test during infection of mammalian cells. We find that even inside the host cell, different strains can be distinguished effortlessly based on their fluorescence. We, therefore, conclude that the pUltra plasmids are a powerful labeling tool especially useful for complex biological experiments such as the visualization of ecosystems of different bacterial species or of enteric pathogens in contact with their hosts. PMID- 27693408 TI - Lung volume reduction for emphysema. AB - Advanced emphysema is a lung disease in which alveolar capillary units are destroyed and supporting tissue is lost. The combined effect of reduced gas exchange and changes in airway dynamics impairs expiratory airflow and leads to progressive air trapping. Pharmacological therapies have limited effects. Surgical resection of the most destroyed sections of the lung can improve pulmonary function and exercise capacity but its benefit is tempered by significant morbidity. This issue stimulated a search for novel approaches to lung volume reduction. Alternative minimally invasive approaches using bronchoscopic techniques including valves, coils, vapour thermal ablation, and sclerosant agents have been at the forefront of these developments. Insertion of endobronchial valves in selected patients could have benefits that are comparable with lung volume reduction surgery. Endobronchial coils might have a role in the treatment of patients with emphysema with severe hyperinflation and less parenchymal destruction. Use of vapour thermal energy or a sclerosant might allow focal treatment but the unpredictability of the inflammatory response limits their current use. In this Review, we aim to summarise clinical trial evidence on lung volume reduction and provide guidance on patient selection for available therapies. PMID- 27693409 TI - Serum Paraoxonase activity in relation to lipid profile in Age-related Macular Degeneration patients. AB - Age-related Macular Degeneration (AMD) is a multifactorial disease causing visual impairment in old age. Oxidative stress is one of the main contributors for the disease progression. Paraoxonase (PON), a HDL-resident antioxidant enzyme which removes oxidized low density lipoprotein (oxLDL), which is not studied much in AMD. This study assesses the PON activities in relation to the lipid status and genetic variants in AMD patients. In this prospective case-control study, a total of 48 AMD patients and 30 unrelated healthy controls were recruited. The serum oxLDL and Plasma Homocysteine (Hcy) levels were estimated by ELISA. Plasma Homocysteine thiolactone (HCTL) was estimated by HPLC. Serum PON activities were estimated by spectrophotometry. PON gene expression was assessed by qPCR and protein expression by western blot, immunofluorescence and FACS analysis. Two known single nucleotide polymorphisms (SNPs) in the coding region of PON1, Q192R and L55M variants were checked in the AMD patients and controls and their association with PON activity and lipid levels were determined. Serum paraoxonase (PONase) and thiolactonase (PON-HCTLase) activities were significantly elevated in AMD patients than in controls apart from elevated serum levels of total cholesterol (TC), triglycerides (TG), oxLDL. While serum LDL levels in AMD patients correlate positively with PON HCTLase activity, the serum high density lipoprotein (HDL) correlates with both PONase and PON-HCTLase activities. However, multiple regression analysis showed that, amongst the parameters, only serum TG was a significant risk factor for AMD, after adjusting for demographic parameters as well as cataract. PON2 was significantly increased at the level of gene expression (p = 0.03) as seen in circulating peripheral blood mononuclear cells (PBMC) of AMD patients possibly mediated by the transcription factor SP1, that showed 2-fold increase. PON1 and 2 protein expressions also showed significant increase in the PBMC of AMD patients. At serum level, PON1 protein was significantly increased in AMD patients. Cholesterol transporters such as CD36, SR-B1 and ABCA1 gene expressions were also found to be higher (1.5, 1.9 and 2.4-fold respectively) in AMD, though not statistically significant. While the wet AMD (CNV) was found to be associated with increase in oxLDL and serum PONase activity, the dry AMD was associated with increased HDL and serum PON-HCTLase activity. The genotype and allele frequencies of Q192R & L55M were not significantly different between AMD patients and controls. However, altered lipid status and PON activities were associated with the genotype in AMD patients. A higher enzyme activity was observed for the RR genotype of Q192R in the cohort, irrespective of case and control. Thus the PON genotype and phenotype seem to play a role in the pathogenesis of AMD.

Dis. 49 (2012) 147-151]. PMID- 27693412 TI - Autocratic strategies for alternating games. AB - Repeated games have a long tradition in the behavioral sciences and evolutionary biology. Recently, strategies were discovered that permit an unprecedented level of control over repeated interactions by enabling a player to unilaterally enforce linear constraints on payoffs. Here, we extend this theory of "zero determinant" (or, more generally, "autocratic") strategies to alternating games, which are often biologically more relevant than traditional synchronous games. Alternating games naturally result in asymmetries between players because the first move matters or because players might not move with equal probabilities. In a strictly-alternating game with two players, X and Y, we give conditions for the existence of autocratic strategies for player X when (i) X moves first and (ii) Y moves first. Furthermore, we show that autocratic strategies exist even for (iii) games with randomly-alternating moves. Particularly important categories of autocratic strategies are extortionate and generous strategies, which enforce unfavorable and favorable outcomes for the opponent, respectively. We illustrate these strategies using the continuous Donation Game, in which a player pays a cost to provide a benefit to the opponent according to a continuous cooperative investment level. Asymmetries due to alternating moves could easily arise from dominance hierarchies, and we show that they can endow subordinate players with more autocratic strategies than dominant players. PMID- 27693410 TI - An important role for adenine, cholera toxin, hydrocortisone and triiodothyronine in the proliferation, self-renewal and differentiation of limbal stem cells in vitro. AB - The cornea is a self-renewing tissue located at the front of the eye. Its transparency is essential for allowing light to focus onto the retina for visual perception. The continuous renewal of corneal epithelium is supported by limbal stem cells (LSCs) which are located in the border region between conjunctiva and cornea known as the limbus. Ex vivo expansion of LSCs has been successfully applied in the last two decades to treat patients with limbal stem cell deficiency (LSCD). Various methods have been used for their expansion, yet the most widely used culture media contains a number of ingredients derived from animal sources which may compromise the safety profile of human LSC transplantation. In this study we sought to understand the role of these components namely adenine, cholera toxin, hydrocortisone and triiodothyronine with the aim of re-defining a safe and GMP compatible minimal media for the ex vivo expansion of LSCs on human amniotic membrane. Our data suggest that all four components play a critical role in maintaining LSC proliferation and promoting LSC self-renewal. However removal of adenine and triiodothyronine had a more profound impact and led to LSC differentiation and loss of viability respectively, suggesting their essential role for ex vivo expansion of LSCs. Replacement of each of the components with GMP-grade reagents resulted in equal growth to non-GMP grade media, however an enhanced differentiation of LSCs was observed, suggesting that additional combinations of GMP grade reagents need to be tested to achieve similar or better level of LSC maintenance in the same manner as the traditional LSC media. PMID- 27693413 TI - Levetiracetam treatment influences blood-brain barrier failure associated with angiogenesis and inflammatory responses in the acute phase of epileptogenesis in post-status epilepticus mice. AB - Our previous study showed that treatment with levetiracetam (LEV) after status epilepticus (SE) termination by diazepam might prevent the development of spontaneous recurrent seizures via the inhibition of neurotoxicity induced by brain edema events. In the present study, we determined the possible molecular and cellular mechanisms of LEV treatment after termination of SE. To assess the effect of LEV against the brain alterations after SE, we focused on blood-brain barrier (BBB) dysfunction associated with angiogenesis and brain inflammation. The consecutive treatment of LEV inhibited the temporarily increased BBB leakage in the hippocampus two days after SE. At the same time point, the LEV treatment significantly inhibited the increase in the number of CD31-positive endothelial immature cells and in the expression of angiogenic factors. These findings suggested that the increase in neovascularization led to an increase in BBB permeability by SE-induced BBB failure, and these brain alterations were prevented by LEV treatment. Furthermore, in the acute phase of the latent period, pro-inflammatory responses for epileptogenic targets in microglia and astrocytes of the hippocampus activated, and these upregulations of pro-inflammatory-related molecules were inhibited by LEV treatment. These findings suggest that LEV is likely involved in neuroprotection via anti-angiogenesis and anti-inflammatory activities against BBB dysfunction in the acute phase of epileptogenesis after SE. PMID- 27693414 TI - Increased striatal VMAT2 binding in mice after chronic administration of methcathinone and manganese. AB - Intravenous use of a psychostimulant drug containing methcathinone (ephedrone) and manganese causes an irreversible extrapyramidal syndrome in drug abusers. We aimed to reproduce the syndrome in mice to evaluate dopaminergic damage. C57/B6 mice were intraperitoneally injected once a day with the study drug or saline for a period of 27 weeks. Motor activity was recorded in an automated motility-box. After 13 and 27 weeks of treatment, ex vivo digital autoradiography was performed using [11C]dihydrotetrabenazine ([11C]DTBZ). After 27 weeks of treatment [11C]DTBZ autoradiography demonstrated a significant increase in the striatum-to cerebellum binding ratio compared with saline treated controls. At the same time point, there was no evident change in motor activity. Increased [11C]DTBZ binding may indicate vesicular monoamine transporter type 2 (VMAT2) function is altered. The lack of extrapyramidal symptoms in animals could be attributed to low dosing regimen or high metabolic rate. PMID- 27693415 TI - Altered melatonin MT1 receptor expression in the ventral midbrain following 6 hydroxydopamine lesions in the rat medial forebrain bundle. AB - The indoleamine hormone melatonin protects dopamine neurons in the rat nigrostriatal pathway following 6-hydroxydopamine lesioning, and an increase in striatal melatonin levels has been detected in this model of Parkinson's disease. Melatonin induces the expression of tyrosine hydroxylase, the rate-limiting enzyme for dopamine synthesis, in the ventral midbrain, where G protein-coupled melatonin receptors are present. Based on the interaction between the melatonergic and dopaminergic systems, we hypothesized that 6-hydroxydopamine induced degeneration of dopamine neurons would affect the expression of melatonin receptors in the nigrostriatal pathway. Following unilateral injection of 6 hydroxydopamine into the rat striatum or medial forebrain bundle, there was a significant increase in apomorphine-induced contralateral rotations in lesioned animals as compared to sham controls. A loss of tyrosine hydroxylase immunoreactivity and/or immunofluorescence in the striatum and substantia nigra was seen in animals lesioned in either the striatum or medial forebrain bundle, indicating degeneration of dopamine neurons. There were no significant differences in melatonin MT1 receptor protein expression in the striatum or substantia nigra, between intrastriatally lesioned animals and sham controls. In contrast, lesions in the medial forebrain bundle caused a significant increase in MT1 receptor mRNA expression (p<0.03) on the lesioned side of the ventral midbrain, as compared with the contralateral side. Given the presence of MT1 receptors on neurons in the ventral midbrain, these results suggest that a compensatory increase in MT1 transcription occurs to maintain expression of this receptor and neuroprotective melatonergic signaling in the injured brain. PMID- 27693416 TI - Sulforaphane activates the cerebral vascular Nrf2-ARE pathway and suppresses inflammation to attenuate cerebral vasospasm in rat with subarachnoid hemorrhage. AB - Nrf2-ARE pathway reportedly plays a protective role in several central nervous system diseases. No study has explored the role of the Nrf2-ARE pathway in cerebral vasospasm(CVS) after subarachnoid hemorrhage(SAH). The purpose of the present study was to investigate the activation of the cerebral vascular Nrf2-ARE pathway and to determine the potential role of this pathway in the development of CVS following SAH. We investigated whether the administration of sulforaphane (SFN, a specific Nrf2 activator) modulated vascular caliber, Nrf2-ARE pathway activity, proinflammatory cytokine expression, and clinical behavior in a rat model of SAH. A two-hemorrhage protocol was used to generate an animal model of SAH in male Sprague-Dawley rats. Administration of SFN to these rats following SAH enhanced the activity of the Nrf2-ARE pathway and suppressed the release of proinflammatory cytokines. Vasospasm was markedly attenuated in the basilar arteries after SFN therapy. Additionally, SFN administration significantly ameliorated two behavioral functions disrupted by SAH. These results suggest that SFN has a therapeutic benefit in post-SAH, and this may be due to elevated Nrf2 ARE pathway activity and inhibition of cerebral vascular proinflammatory cytokine expression. PMID- 27693418 TI - Tumour-necrosis factor-alpha induces heparan sulfate 6-O-endosulfatase 1 (Sulf-1) expression in fibroblasts. AB - Heparan sulfate (HS) 6-O-endosulfatases (Sulfs) have emerged recently as critical regulators of many physiological and pathological processes. By removing 6-O sulfates from specific HS sequences, they modulate the activities of a variety of growth factors and morphogens, including fibroblast growth factor (FGF)-1. However, little is known about the functions of Sulfs in inflammation. Tumour necrosis factor (TNF)-alpha plays an important role in regulating the behaviour of fibroblasts. In this study, we examined the effect of this inflammatory cytokine on the expression of Sulfs in human MRC-5 fibroblasts. Compositional analysis of HS from TNF-alpha-treated cells showed a strong reduction in the amount of the trisulfated UA2S-GlcNS6S disaccharide, which suggested a selective reaction of 6-O-desulfation. Real-time PCR analysis revealed that TNF-alpha increased Sulf-1 expression in a dose- and time-dependent manner, via a mechanism involving NF-KB, ERK1/2 and p38 MAPK. In addition, we confirmed that cell stimulation with TNF-alpha was accompanied by the secretion of an active form of Sulf-1. To study the function of Sulf- 1, we examined the responses induced by FGF-1. We showed that ERK1/2 activation and cell proliferation were markedly reduced in TNF-alpha-treated MRC-5 cells compared with untreated cells. Silencing the expression of Sulf-1 by RNA interference restored the responses induced by FGF-1, which indicated that TNF-alpha-mediated induction of the sulfatase indeed resulted in alterations of HS biological properties. Taken together, our results indicate that Sulf-1 is responsive to TNF-alpha stimulation and may function as an autocrine regulator of fibroblast expansion in the course of an inflammatory response. PMID- 27693417 TI - Phenotypes associated with psychiatric disorders are sex-specific in a mutant mouse line. AB - Wnt1-Cre- and Wnt1-GAL4 double transgenic (dTg) mice are used to study neural crest cell lineages by utilizing either the Cre/loxP or the GAL4/UAS system. We have previously shown that these mice exhibit behavioral abnormalities that resemble certain behaviors of psychiatric disorders and histologic alterations in the cholinergic and glutamatergic systems in the brain. The objective of the current study was to extend the behavioral analyses in these mice and to determine whether there were any sex-specific differences in the prevalence or severity of these behaviors. In the present study, we demonstrate additional behavioral abnormalities in dTg mice, such as increased locomotor activity, decreased social behavior, and an increased frequency in vertical jumping. Of these, the proclivity for vertical jumping was observed only in male dTg mice. In contrast, MK-801 administration induced increased locomotion in only female dTg mice. Furthermore, the concentrations of prolactin in the sera and oxytocin in the hypothalamus were both reduced only in female dTg mice, compared to controls. These sex-dependent behavioral and hormonal abnormalities in the dTG mice suggest that the phenotype of certain psychiatric disorders may be influenced by both genetic and sex-specific factors. PMID- 27693419 TI - Hypothalamic regulation of body growth and appetite by ghrelin-derived peptides during balanced nutrition or undernutrition. AB - Among the gastrointestinal hormones that regulate food intake and energy homeostasis, ghrelin plays a unique role as the first one identified to increases appetite and stimulate GH secretion. This review highlights the latest mechanism by which ghrelin modulates body growth, appetite and energy metabolism by exploring pharmacological actions of the hormone and consequences of genetic or pharmacological blockade of the ghrelin/GHS-R (Growth Hormone Secretagogue Receptor) system on physiological responses in specific nutritional situations. Within the hypothalamus, novel mechanisms of action of this hormone involve its interaction with other ghrelin-derived peptides, such as desacyl ghrelin and obestatin, which are thought to act as functional ghrelin antagonists, and possible modulation of the GHS-R with other G-protein coupled receptors. During chronic undernutrition such as anorexia nervosa, variations of ghrelin-derived peptides may be an adaptative metabolic response to maintain normal glycemic control. Interestingly, some of ghrelin's metabolic actions are thought to be relayed through modulation of GH, an anabolic and hyperglycemic agent. PMID- 27693420 TI - Association Between 6-Minute Walk Test Distance and Objective Variables of Functional Capacity After Exercise Training in Elderly Heart Failure Patients With Preserved Ejection Fraction: A Randomized Exercise Trial. AB - OBJECTIVE: To evaluate the change in the 6-minute walk test (6-MWT) distance relative to changes in key functional capacity measures after 16 weeks of exercise training in older patients (>=65y) who have heart failure with preserved ejection fraction (HFpEF). DESIGN: Prospective, randomized, single-blinded (by researchers to patient group) comparison of 2 groups of HFpEF patients. SETTING: Hospital and clinic records; ambulatory outpatients. PARTICIPANTS: Participants (N=47) randomly assigned to an attention control (AC) (n=24) or exercise training (ET) (n=23) group. INTERVENTION: The ET group performed cycling and walking at 50% to 70% of peak oxygen uptake (Vo2peak) intensity (3d/wk, 60min each session). MAIN OUTCOME MEASURES: Vo2peak, ventilatory threshold (VT), and 6-MWT distance were measured at baseline and after the 16-week study period. RESULTS: At follow up, the 6-MWT distance was higher than at the baseline in both the ET (11%, P=.005) and AC (9%, P=.004) groups. In contrast, Vo2peak and VT values increased in the ET group (19% and 11%, respectively; P=.001), but decreased in the AC group at follow-up (2% and 0%, respectively). The change in Vo2peak versus 6-MWT distance after training was also not significantly correlated in the AC group (r=.01, P=.95) or in the ET group (r=.13, P=.57). The change in 6-MWT distance and VT (an objective submaximal exercise measure) was also not significantly correlated in the AC group (r=.08, P=.74) or in the ET group (r=.16, P=.50). CONCLUSIONS: The results of this study challenge the validity of using the 6-MWT as a serial measure of exercise tolerance in elderly HFpEF patients and suggest that submaximal and peak exercise should be determined objectively by VT and Vo2peak in this patient population. PMID- 27693421 TI - Feasibility of a Smartphone-Based Exercise Program for Office Workers With Neck Pain: An Individualized Approach Using a Self-Classification Algorithm. AB - OBJECTIVE: To explore the feasibility of a newly developed smartphone-based exercise program with an embedded self-classification algorithm for office workers with neck pain, by examining its effect on the pain intensity, functional disability, quality of life, fear avoidance, and cervical range of motion (ROM). DESIGN: Single-group, repeated-measures design. SETTING: The laboratory and participants' home and work environments. PARTICIPANTS: Offices workers with neck pain (N=23; mean age +/- SD, 28.13+/-2.97y; 13 men). INTERVENTION: Participants were classified as having 1 of 4 types of neck pain through a self-classification algorithm implemented as a smartphone application, and conducted corresponding exercise programs for 10 to 12min/d, 3d/wk, for 8 weeks. MAIN OUTCOME MEASURES: The visual analog scale (VAS), Neck Disability Index (NDI), Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), Fear-Avoidance Beliefs Questionnaire (FABQ), and cervical ROM were measured at baseline and postintervention. RESULTS: The VAS (P<.001) and NDI score (P<.001) indicated significant improvements in pain intensity and functional disability. Quality of life showed significant improvements in the physical functioning (P=.007), bodily pain (P=.018), general health (P=.022), vitality (P=.046), and physical component scores (P=.002) of the SF-36. The FABQ, cervical ROM, and mental component score of the SF-36 showed no significant improvements. CONCLUSIONS: The smartphone based exercise program with an embedded self-classification algorithm improves the pain intensity and perceived physical health of office workers with neck pain, although not enough to affect their mental and emotional states. PMID- 27693423 TI - Possible influence of vitamin D on male reproduction. AB - Vitamin D is a versatile signaling molecule with an established role in the regulation of calcium homeostasis and bone health. In recent years the spectrum of vitamin D target organs has expanded and a reproductive role is supported by the presence of the vitamin D receptor (VDR) and the vitamin D metabolizing enzymes in the gonads, reproductive tract, and human spermatozoa. Interestingly, expression levels of VDR and the vitamin D inactivating enzyme CYP24A1 in human spermatozoa serve as positive predictive markers of semen quality and are higher expressed in spermatozoa from normal than infertile men. VDR mediates a non genomic increase in intracellular calcium concentration, sperm motility, and induces the acrosome reaction. Furthermore, functional animal model studies have shown that vitamin D is important for sex steroid production, estrogen signaling, and semen quality. Cross-sectional clinical studies have supported the notion of a positive association between serum 25-hydroxyvitamin D (25-OHD) level and semen quality in both fertile and infertile men. However, it remains to be determined whether this association reflects a causal effect. The VDR is ubiquitously expressed and activated vitamin D is a regulator of insulin, aromatase, and osteocalcin. Hence, it is plausible that the influence of vitamin D on gonadal function may be mediated indirectly through other vitamin D regulated endocrine factors. Recent studies have indicated that vitamin D supplementation may be beneficial for couples in need of assisted reproductive techniques as high serum vitamin D levels were found to be associated with a higher chance of achieving pregnancy. Randomized clinical trials are needed to determine whether systemic changes in vitamin D metabolites can influence semen quality, fertility, and sex steroid production in infertile men. In this review known and possible future implications of vitamin D in human male reproduction function will be discussed. PMID- 27693422 TI - Endogenously produced nonclassical vitamin D hydroxy-metabolites act as "biased" agonists on VDR and inverse agonists on RORalpha and RORgamma. AB - The classical pathway of vitamin D activation follows the sequence D3->25(OH)D3 >1,25(OH)2D3 with the final product acting on the receptor for vitamin D (VDR). An alternative pathway can be started by the action of CYP11A1 on the side chain of D3, primarily producing 20(OH)D3, 22(OH)D3, 20,23(OH)2D3, 20,22(OH)2D3 and 17,20,23(OH)3D3. Some of these metabolites are hydroxylated by CYP27B1 at C1alpha, by CYP24A1 at C24 and C25, and by CYP27A1 at C25 and C26. The products of these pathways are biologically active. In the epidermis and/or serum or adrenals we detected 20(OH)D3, 22(OH)D3, 20,22(OH)2D3, 20,23(OH)2D3, 17,20,23(OH)3D3, 1,20(OH)2D3, 1,20,23(OH)3D3, 1,20,22(OH)3D3, 20,24(OH)2D3, 1,20,24(OH)3D3, 20,25(OH)2D3, 1,20,25(OH)3D3, 20,26(OH)2D3 and 1,20,26(OH)3D3. 20(OH)D3 and 20,23(OH)2D3 are non-calcemic, while the addition of an OH at C1alpha confers some calcemic activity. Molecular modeling and functional assays show that the major products of the pathway can act as "biased" agonists for the VDR with high docking scores to the ligand binding domain (LBD), but lower than that of 1,25(OH)2D3. Importantly, cell based functional receptor studies and molecular modeling have identified the novel secosteroids as inverse agonists of both RORalpha and RORgamma receptors. Specifically, they have high docking scores using crystal structures of RORalpha and RORgamma LBDs. Furthermore, 20(OH)D3 and 20,23(OH)2D3 have been tested in a cell model that expresses a Tet-on RORalpha or RORgamma vector and a RORE-LUC reporter (ROR-responsive element), and in a mammalian 2-hybrid model that test interactions between an LBD-interacting LXXLL peptide and the LBD of RORalpha/gamma. These assays demonstrated that the novel secosteroids have ROR-antagonist activities that were further confirmed by the inhibition of IL17 promoter activity in cells overexpressing RORalpha/gamma. In conclusion, endogenously produced novel D3 hydroxy-derivatives can act both as "biased" agonists of the VDR and/or inverse agonists of RORalpha/gamma. We suggest that the identification of large number of endogenously produced alternative hydroxy-metabolites of D3 that are biologically active, and of possible alternative receptors, may offer an explanation for the pleiotropic and diverse activities of vitamin D, previously assigned solely to 1,25(OH)2D3 and VDR. PMID- 27693424 TI - Differentiation of Human Embryonic Stem Cells to Endothelial Progenitor Cells on Laminins in Defined and Xeno-free Systems. AB - A major hurdle for in vitro culturing of primary endothelial cells (ECs) is that they readily dedifferentiate, hampering their use for therapeutic applications. Human embryonic stem cells (hESCs) may provide an unlimited cell source; however, most current protocols deriving endothelial progenitor cells (EPCs) from hESCs use direct differentiation approaches albeit on undefined matrices, yet final yields are insufficient. We developed a method to culture monolayer hESCs on stem cell niche laminin (LN) LN511 or LN521 matrix. Here, we report a chemically defined, xeno-free protocol for differentiation of hESCs to EPCs using LN521 as the main culture substrate. We were able to generate ~95% functional EPCs defined as VEGFR2+CD34+CD31+VE-Cadherin+. RNA-sequencing analyses of hESCs, EPCs, and primary human umbilical vein endothelial cells showed differentiation-related EC expression signatures, regarding basement membrane composition, cell-matrix interactions, and changes in endothelial lineage markers. Our results may facilitate production of stable ECs for the treatment of vascular diseases and in vitro cell modeling. PMID- 27693425 TI - Amyloid beta Is Not the Major Factor Accounting for Impaired Adult Hippocampal Neurogenesis in Mice Overexpressing Amyloid Precursor Protein. AB - Adult hippocampal neurogenesis was impaired in several Alzheimer's disease models overexpressing mutant human amyloid precursor protein (hAPP). However, the effects of wild-type hAPP on adult neurogenesis and whether the impaired adult hippocampal neurogenesis was caused by amyloid beta (Abeta) or APP remained unclear. Here, we found that neurogenesis was impaired in the dentate gyrus (DG) of adult mice overexpressing wild-type hAPP (hAPP-I5) compared with controls. However, the adult hippocampal neurogenesis was more severely impaired in hAPP-I5 than that in hAPP-J20 mice, which express similar levels of hAPP mRNA but much higher levels of Abeta. Furthermore, reducing Abeta levels did not affect the number of doublecortin-positive cells in the DG of hAPP-J20 mice. Our results suggested that hAPP was more likely an important factor inhibiting adult neurogenesis, and Abeta was not the major factor affecting neurogenesis in the adult hippocampus of hAPP mice. PMID- 27693426 TI - Restoration of Corneal Transparency by Mesenchymal Stem Cells. AB - Transparency of the cornea is indispensable for optimal vision. Ocular trauma is a leading cause of corneal opacity, leading to 25 million cases of blindness annually. Recently, mesenchymal stem cells (MSCs) have gained prominence due to their inflammation-suppressing and tissue repair functions. Here, we investigate the potential of MSCs to restore corneal transparency following ocular injury. Using an in vivo mouse model of ocular injury, we report that MSCs have the capacity to restore corneal transparency by secreting high levels of hepatocyte growth factor (HGF). Interestingly, our data also show that HGF alone can restore corneal transparency, an observation that has translational implications for the development of HGF-based therapy. PMID- 27693428 TI - Anticancer drug-loaded hydrogels as drug delivery systems for the local treatment of glioblastoma. AB - Among central nervous system tumors, Glioblastoma (GBM) is the most common, aggressive and neurological destructive primary brain tumor in adults. Standard care therapy for GBM consists in surgical resection of the accessible tumor (without causing neurological damage) followed by chemoradiation. However, several obstacles limit the assessment of tumor response and the delivery of cytotoxic agents at the tumor site, leading to a lack of effectiveness of conventional treatments against GBM and fatal outcome. Despite the efforts of the scientific community to increase the long-term benefits of GBM therapy, at the moment GBM remains incurable. Among the strategies that have been adopted in the last two decades to find new and efficacious therapies for the treatment of GBM, the local delivery of chemotherapeutic drugs in the tumor resection cavity emerged. In this review, our aim is to provide an overview on hydrogels loaded with anticancer drugs for the treatment of GBM recently used in preclinical and clinical studies, their advantages and major limitations for clinical translation. This review is divided in three parts: the first one describes the context of GBM and its current treatments, with a highlight on the role of local delivery in GBM treatment and the development of GBM resection murine models. Then, recent developments in the use of anticancer drug-loaded hydrogels for the treatment of GBM will be detailed. The final section will be focused on the limitations for in vivo studies, clinical translation and the clinical perspectives to the development of hydrogels.

AB - Huntington's disease (HD) is characterized by fatal motoric failures induced by loss of striatal medium spiny neurons. Neuronal cell death has been linked to impaired expression and axonal transport of the neurotrophin BDNF (brain-derived neurotrophic factor). By transplanting embryonic stem cell-derived neural progenitors overexpressing BDNF, we combined cell replacement and BDNF supply as a potential HD therapy approach. Transplantation of purified neural progenitors was analyzed in a quinolinic acid (QA) chemical and two genetic HD mouse models (R6/2 and N171-82Q) on the basis of distinct behavioral parameters, including CatWalk gait analysis. Explicit rescue of motor function by BDNF neural progenitors was found in QA-lesioned mice, whereas genetic mouse models displayed only minor improvements. Tumor formation was absent, and regeneration was attributed to enhanced neuronal and striatal differentiation. In addition, adult neurogenesis was preserved in a BDNF-dependent manner. Our findings provide significant insight for establishing therapeutic strategies for HD to ameliorate neurodegenerative symptoms. PMID- 27693429 TI - Fibromodulin: A regulatory molecule maintaining cellular architecture for normal cellular function. AB - Fibromodulin (FMOD) is a small leucine-rich proteoglycan that plays roles in a series of biological and pathophysiological processes. The interaction between FMOD and lysyl oxidase (LOX; collagen cross-linking enzyme) helps regulate extracellular matrix composition, and thereby, provides a permissive environment for regulating cellular turnover. FMOD has been mostly studied in the context of matrix component assembly, but during recent years its association with muscle development, cell reprogramming, and the angiogenic program have demonstrated its activities well beyond extracellular matrix maintenance. In fact, the involvement of FMOD in these cellular processes places it the centrum of cellular behaviour and ultimately of tissue properties. Thus, a clear view of the impact FMOD has on tissue integrity would aid its exploitation for tissue modelling and in the treatment of different disorders. PMID- 27693430 TI - miR-483 is a self-regulating microRNA and can activate its own expression via USF1 in HeLa cells. AB - MicroRNAs (miRNAs) are small non-coding RNAs that constitute a fundamental part of post-transcriptional gene regulation in mammalian cells. We have recently identified the intronic miR-483, which functions as an important regulator of protein synthesis during mild hypothermia in human and rodent cells. Since only very little is known about transcriptional regulation of intronic miRNAs and their host genes, we thoroughly investigated the regulation of miR-483 expression and its host gene IGF2 in HeLa cells. We demonstrate that miR-483 is regulated and expressed independently of its host gene IGF2 during mild hypothermia. Strikingly, we also discovered that miR-483 enhances its own transcription by up regulation of the transcription factor USF1, which activates a promoter element upstream of the MIR483 gene. However, since the USF1 mRNA lacks binding sites for miR-483-5p and -3p, USF1 expression is likely enhanced in an indirect manner. Our results suggest that miR-483 may self-regulate its own expression independently of its host gene IGF2 in human HeLa cells. This points towards a novel feed forward mechanism, in which selected intronic miRNAs may activate their own expression by transcriptional activation of upstream regulators. PMID- 27693431 TI - Chasing the personalized medicine dream through biomarker validation in colorectal cancer. AB - Colorectal cancer (CRC) is a major health burden worldwide. The optimal approach to the diagnosis, management, and treatment of CRC involves multidisciplinary and integrated management practices. The field is rapidly changing because of recent advancements in delineating the molecular basis of tumorigenesis, introduction of targeted therapy, varied patient response to mainstay chemotherapeutics, biological drugs, and the effective combination regimes being used for treatment. Recent meta-analysis studies, which tend to establish few clinically useful predictor biomarkers, identify inconsistent results and limitations of the trials. Therefore, molecular pathological epidemiology discipline initiatives are promising. Here, we provide an overview of the potential of biomarker validation for personalized medicine by focusing largely on metastatic (m)CRC. We also highlight new candidate predictive and prognostic biomarkers. PMID- 27693432 TI - Pharmaceutical and biomaterial engineering via electrohydrodynamic atomization technologies. AB - Complex micro- and nano-structures enable crucial developments in the healthcare remit (e.g., pharmaceutical and biomaterial sciences). In recent times, several technologies have been developed and explored to address key healthcare challenges (e.g., advanced chemotherapy, biomedical diagnostics and tissue regeneration). Electrohydrodynamic atomization (EHDA) technologies are rapidly emerging as promising candidates to address these issues. The fundamental principle driving EHDA engineering relates to the action of an electric force (field) on flowing conducting medium (formulation) giving rise to a stable Taylor cone. Through careful optimization of process parameters, material properties and selection, nozzle and needle design, and collection substrate method, complex active micro- and nano-structures are engineered. This short review focuses on key selected recent and established advances in the field of pharmaceutical and biomaterial applications. PMID- 27693433 TI - Follicular lymphoma (FL): Immunological tolerance theory in FL. AB - The ultimate cause of follicular lymphoma (FL) remains unknown. Remarkably, almost nothing is known about immunological tolerance mechanisms that might contribute to FL development. Immunological tolerance mechanisms, like other stimuli, also induce persistent changes of B cell receptors that induce genetic instability and molecular aberrations promoting the development of a neoplasm. Using the same method as Burnet, we provide a new perspective taking advantage of the comparison of a normal linear B cell differentiation process and FL development within the framework of clonal selection theory. We propose that FL is a malignancy of cells that acquire both translocation t(14;18) and self-BCR, inducing them to proliferate and mature, resistant to negative selection. Additional genetic damage induced by non-apoptotic tolerance mechanisms, such as receptor editing, may transform a self-reactive B cell with t(14;18) into an FL. The result of tolerogenic mechanisms and genetic aberrations is the survival of FL B cell clones with similar markers and homogenous gene expression signatures despite the different stages of maturation at which the molecular damage occurs. To antagonize further growth advantage due to self-antigen recognition and chronic activation of tolerance mechanisms in the apoptosis-resistant background of FL B cells, inhibitors of BCR signaling may be promising therapeutic options. PMID- 27693435 TI - The different oscillation patterns of alpha band in the early and later stages of working memory maintenance. AB - A putative functional role for alpha oscillations in working memory remains controversial. However, recent evidence suggests that such oscillation may reflect distinct phases of working memory processing. The present study investigated alpha band (8-13Hz) activity during the maintenance stage of working memory using a modified Sternberg working memory task. Our results reveal that alpha power was concentrated primarily in the occipital cortex and was decreased during the early stage of maintenance (0-600ms), and subsequently increased during the later stage of maintenance (1000-1600ms). We suggest that reduced alpha power may be involved in focused attention during the working memory maintenance, whereas increased alpha power may reflect suppression of visual stimuli to facilitate internal processing related to the task. This interpretation is generally consistent with recent reports suggesting that variations in alpha power are associated with the representation and processing of information in the discrete time intervals during the working memory maintenance. PMID- 27693434 TI - Distinct regulation of atonal in a visual organ of Drosophila: Organ-specific enhancer and lack of autoregulation in the larval eye. AB - Drosophila has three types of visual organs, the larval eyes or Bolwig's organs (BO), the ocelli (OC) and the compound eyes (CE). In all, the bHLH protein Atonal (Ato) functions as the proneural factor for photoreceptors and effects the transition from progenitor cells to differentiating neurons. In this work, we investigate the regulation of ato expression in the BO primordium (BOP). Surprisingly, we find that ato transcription in the BOP is entirely independent of the shared regulatory DNA for the developing CE and OC. The core enhancer for BOP expression, atoBO, lies ~6kb upstream of the ato gene, in contrast to the downstream location of CE and OC regulatory elements. Moreover, maintenance of ato expression in the neuronal precursors through autoregulation-a common and ancient feature of ato expression that is well-documented in eyes, ocelli and chordotonal organs-does not occur in the BO. We also show that the atoBO enhancer contains two binding sites for the transcription factor Sine oculis (So), a core component of the progenitor specification network in all three visual organs. These binding sites function in vivo and are specifically bound by So in vitro. Taken together, our findings reveal that the control of ato transcription in the evolutionarily derived BO has diverged considerably from ato regulation in the more ancestral compound eyes and ocelli, to the extent of acquiring what appears to be a distinct and evolutionarily novel cis-regulatory module. PMID- 27693436 TI - The effect of varenicline on binge-like ethanol consumption in mice is beta4 nicotinic acetylcholine receptor-independent. AB - BACKGROUND: Our laboratory has previously shown that the smoking-cessation agent varenicline, an agonist/partial agonist of alpha4beta2*, alpha3beta4*, alpha3beta2*, alpha6beta2* (* indicates the possibility of additional subunits) and alpha7 subunits of nicotinic acetylcholine receptors (nAChRs), reduces ethanol consumption in rats only after long-term exposure (12 weeks). As compounds having partial agonistic activity on alpha3beta4* nAChRs were shown to decrease ethanol consumption in rodents, we assessed here the involvement of the beta4 subunit in the effect of varenicline in the reduction of short- and long term binge-like ethanol drinking in mice. METHODS: We used the well-validated drinking-in-the-dark (DID) paradigm to model chronic binge-like ethanol drinking in beta4-/- and beta4+/+ littermate mice and compare the effect of intraperitoneal injection of varenicline (2mg/kg) on ethanol intake following short- (4 weeks) or long-term (12 weeks) exposure. RESULTS: Drinking pattern and amounts of ethanol intake were similar in beta4-/- and beta4+/+ mice. Interestingly, our results showed that varenicline reduces ethanol consumption following short- and long-term ethanol exposure in the DID. Although the effect of varenicline on the reduction of ethanol consumption was slightly more pronounced in beta4-/- mice than their beta4+/+ littermates no significant differences were observed between genotypes. CONCLUSION: In mice, varenicline reduces binge-like ethanol consumption both after short- and long-term exposure in the DID and this effect is independent of beta4 nAChR subunit. PMID- 27693437 TI - Parkinson's disease classification using gait analysis via deterministic learning. AB - Gait analysis plays an important role in maintaining the well-being of human mobility and health care, and is a valuable tool for obtaining quantitative information on motor deficits in Parkinson's disease (PD). In this paper, we propose a method to classify (diagnose) patients with PD and healthy control subjects using gait analysis via deterministic learning theory. The classification approach consists of two phases: a training phase and a classification phase. In the training phase, gait characteristics represented by the gait dynamics are derived from the vertical ground reaction forces under the usual and self-selected paces of the subjects. The gait dynamics underlying gait patterns of healthy controls and PD patients are locally accurately approximated by radial basis function (RBF) neural networks. The obtained knowledge of approximated gait dynamics is stored in constant RBF networks. The gait patterns of healthy controls and PD patients constitute a training set. In the classification phase, a bank of dynamical estimators is constructed for all the training gait patterns. Prior knowledge of gait dynamics represented by the constant RBF networks is embedded in the estimators. By comparing the set of estimators with a test gait pattern of a certain PD patient to be classified (diagnosed), a set of classification errors are generated. The average L1 norms of the errors are taken as the classification measure between the dynamics of the training gait patterns and the dynamics of the test PD gait pattern according to the smallest error principle. When the gait patterns of 93 PD patients and 73 healthy controls are classified with five-fold cross-validation method, the accuracy, sensitivity and specificity of the results are 96.39%, 96.77% and 95.89%, respectively. Based on the results, it may be claimed that the features and the classifiers used in the present study could effectively separate the gait patterns between the groups of PD patients and healthy controls. PMID- 27693438 TI - Efficacy of chlorhexidine application to umbilical cord on neonatal mortality in Pemba, Tanzania: a community-based randomised controlled trial. AB - BACKGROUND: In low-income countries, including the east African region, a third of neonatal deaths are due to infections. A substantial proportion of these have been attributed to sepsis, which can result from umbilical cord infections. Evidence from Asia suggests that chlorhexidine application to the neonatal umbilical cord reduces mortality, but no data from Africa are available. We aimed to assess the effect of umbilical cord cleansing with 4% chlorhexidine solution on neonatal mortality and omphalitis in rural settings of sub-Saharan Africa. METHODS: We did a community-based randomised controlled trial on Pemba Island, Zanzibar, Tanzania. All eligible babies (aged 1 h to 48 h, without congenital malformations) from hospital-based and community-based deliveries on Pemba Island were enrolled. Participants were randomly assigned to either 4% free chlorhexidine for cord care or to dry cord care using a computer-generated random sequence. For babies allocated to the chlorhexidine group, mothers or caretakers were advised to apply the solution to the cord every day until 3 days after the cord had dropped off. Cord stumps were examined for redness, pus, swelling, and foul odour on day 0, 1, 4, 10, and 28. The primary outcome for this study was mortality until day 28 on an intention-to-treat basis. The trial is registered with ClinicalTrials.gov, number NCT01528852. FINDINGS: Between May 19, 2011, and Aug 31, 2014, 36 911 newborn babies were enrolled into the chlorhexidine (n=18 015) and dry cord care study (n=18 896) groups. 17 468 (96.9%) of 18 015 neonates in the chlorhexidine group were available for complete follow-up (28 days) compared with 18 384 (97.3%) of 18 896 neonates in the dry cord care group. Mortality rate in the chlorhexidine group (10.5 deaths per 1000 livebirths) was not significantly lower than that in the dry cord care group (11.7 per 1000 livebirths; relative risk 0.90, 0.74-1.09; p=0.27). INTERPRETATION: Our findings do not support the use of chlorhexidine for reduction of neonatal mortality in this east African setting, which might not justify a change in the WHO policy. To inform global policy, a detailed meta-analysis and pooled analysis needs to be undertaken using data from both African and Asian settings. FUNDING: Bill & Melinda Gates Foundation. PMID- 27693440 TI - No reason to change WHO guidelines on cleansing the umbilical cord. PMID- 27693439 TI - Effectiveness of 4% chlorhexidine umbilical cord care on neonatal mortality in Southern Province, Zambia (ZamCAT): a cluster-randomised controlled trial. AB - BACKGROUND: Chlorhexidine umbilical cord washes reduce neonatal mortality in south Asian populations with high neonatal mortality rates and predominantly home based deliveries. No data exist for sub-Saharan African populations with lower neonatal mortality rates or mostly facility-based deliveries. We compared the effect of chlorhexidine with dry cord care on neonatal mortality rates in Zambia. METHODS: We undertook a cluster-randomised controlled trial in Southern Province, Zambia, with 90 health facility-based clusters. We enrolled women who were in their second or third trimester of pregnancy, aged at least 15 years, and who would remain in the catchment area for follow-up of 28 days post-partum. Newborn babies received clean dry cord care (control) or topical application of 10 mL of a 4% chlorhexidine solution once per day until 3 days after cord drop (intervention), according to cluster assignment. We used stratified, restricted randomisation to divide clusters into urban or two rural groups (located <40 km or >=40 km to referral facility), and randomly assigned clusters (1:1) to use intervention (n=45) or control treatment (n=45). Sites, participants, and field monitors were aware of their study assignment. The primary outcomes were all cause neonatal mortality within 28 days post-partum and all-cause neonatal mortality within 28 days post-partum among babies who survived the first 24 h of life. Analysis was by intention to treat. Neonatal mortality rate was compared with generalised estimating equations. This study is registered at ClinicalTrials.gov (NCT01241318). FINDINGS: From Feb 15, 2011, to Jan 30, 2013, we screened 42 356 pregnant women and enrolled 39 679 women (mean 436.2 per cluster [SD 65.3]), who had 37 856 livebirths and 723 stillbirths; 63.8% of deliveries were facility-based. Of livebirths, 18 450 (99.7%) newborn babies in the chlorhexidine group and 19 308 (99.8%) newborn babies in the dry cord care group were followed up to day 28 or death. 16 660 (90.0%) infants in the chlorhexidine group had chlorhexidine applied within 24 h of birth. We found no significant difference in neonatal mortality rate between the chlorhexidine group (15.2 deaths per 1000 livebirths) and the dry cord care group (13.6 deaths per 1000 livebirths; risk ratio [RR] 1.12, 95% CI 0.88-1.44). Eliminating day 0 deaths yielded similar findings (RR 1.12, 95% CI 0.86-1.47). INTERPRETATION: Despite substantial reductions previously reported in south Asia, chlorhexidine cord applications did not significantly reduce neonatal mortality rates in Zambia. Chlorhexidine cord applications do not seem to provide clear benefits for newborn babies in settings with predominantly facility-based deliveries and lower (<30 deaths per 1000 livebirths) neonatal mortality rates.

AB - Over 60% of people aged over 65 are affected by multiple morbidities, which are more difficult to treat, generate increased healthcare costs and lead to poor quality of life compared to individual diseases. With the number of older people steadily increasing this presents a societal challenge. Age is the major risk factor for age-related diseases and recent research developments have led to the proposal that pharmacological interventions targeting common mechanisms of ageing may be able to delay the onset of multimorbidity. Here we review the state of the knowledge of multimorbidity, appraise the available evidence supporting the role of mechanisms of ageing in the development of the most common age-related diseases and assess potential molecules that may successfully target those key mechanisms. PMID- 27693443 TI - The effects of lower-body compression garments on walking performance and perceived exertion in adults with CVD risk factors. AB - OBJECTIVES: Compression garments are used by athletes in attempts to enhance performance and recovery, although evidence to support their use is equivocal. Reducing the exertion experienced during exercise may encourage sedentary individuals to increase physical activity. The aim of this study was to assess the effect of compression garments on walking performance (self-paced and enforced pace) and rate of perceived exertion (RPE) in adults who presented with two or more CVD risk factors. Participants (n=15, 10 female, 58.9+/-11.5 years, BMI 27.5+/-4.5kgm2) were recruited. DESIGN: A repeated measures design. METHODS: Participants were randomised to Modified Bruce Protocol (enforced pace), or the 6min walk test (self-paced), and completed the test wearing compression garments or normal exercise clothes (Control). Outcome measures included stage completed, gross efficiency (%) and RPE in Modified Bruce Protocol, and distance walked (m) and RPE in 6 min walk test. RESULTS: In the Modified Bruce Protcol participants had a higher RPE (15.5+/-2.5 vs 14.3+/-2.2) and a lower efficiency (19.1+/-5.9 vs 21.1+/-6.7) in the compression garment condition compared with control, p<0.05. In the 6 min walk test participants walked 9% less in the compression garment condition (p<0.05) but did not have a lower RPE. CONCLUSIONS: Compared with previous studies reporting enhanced or no effects of compression garments on performance or RPE, this study shows adverse effects of such clothing in untrained individuals with CVD risk factors. The mechanisms underlying this negative effect require further exploration. Use of garments designed for the athletic individuals may not be suitable for the wider population. PMID- 27693442 TI - Hip abductor strength and lower extremity running related injury in distance runners: A systematic review. AB - OBJECTIVES: Determine the association between hip abduction strength and lower extremity running related injury in distance runners. DESIGN: Systematic review. METHODS: Prospective longitudinal and cross sectional studies that quantified hip abduction strength and provided diagnosis of running related injury in distance runners were included and assessed for quality. Effect size was calculated for between group differences in hip abduction strength. RESULTS: Of the 1841 articles returned in the initial search, 11 studies matched all inclusion criteria. Studies were grouped according to injury: iliotibial band syndrome, patellofemoral pain syndrome, medial tibial stress syndrome, tibial stress fracture, and Achilles tendinopathy, and examined for strength differences between injured and non-injured groups. Meaningful differences were found in the studies examining iliotibial band syndrome. Three of five iliotibial band syndrome articles found weakness in runners with iliotibial band syndrome; two were of strong methodological rigor and both of those found a relationship between weakness and injury. Other results did not form associative or predictive relationships between weakness and injury in distance runners. CONCLUSIONS: Hip abduction weakness evaluated by hand held dynamometer may be associated with iliotibial band syndrome in distance runners as suggested by several cross sectional studies but is unclear as a significant factor for the development of patellofemoral pain syndrome, medial tibial stress syndrome, tibial stress fracture or Achilles tendinopathy according to the current literature. Future studies are needed with consistent methodology and inclusion of all distance running populations to determine the significance of hip abduction strength in relationship to lower extremity injury. PMID- 27693444 TI - Appearance of Far Peripheral Retina in Normal Eyes by Ultra-widefield Fluorescein Angiography. AB - PURPOSE: To characterize the appearance of the far peripheral retina of normal eyes using ultra-widefield fluorescein angiography (UWFA). DESIGN: Cross sectional study. METHODS: This study enrolled 101 eyes with best-corrected visual acuity >=20/20, with refractive error <3.00 diopters, and without visible retinal pathologic changes under a slit lamp-based condensing lens. The far peripheral retina was detected by UWFA. Ciliary body thickness (CBT) at 3 mm (CBT1) and 2 mm (CBT2) posterior to the scleral spur was measured by ultrasound biomicroscopy. RESULTS: In the far peripheral retina, granular background fluorescence (GB) appeared in all eyes (100%), a mottled fluorescent band (MB) appeared in 44 eyes (43.6%), and retinal vascular leakage (VL) appeared in 20 eyes (19.8%). According to peripheral angiographic findings, the eyes were allocated into 3 groups: Group 1 (MB- and VL-), Group 2 (MB+ and VL-), and Group 3 (MB-/+ and VL+). Ultrasound biomicroscopy showed ciliary body edema and exudates in Group 3. The mean CBT1 (mm) and CBT2 (mm) of Group 3 were greater than those of Group 1 and Group 2 (0.315 +/- 0.037 vs 0.240 +/- 0.019 vs 0.251 +/- 0.030; 0.571 +/- 0.084 vs 0.375 +/- 0.051 vs 0.410 +/- 0.050, P < .001 for both CBT1 and CBT2). The mean CBT1 and CBT2 showed no difference between Group 1 and Group 2 (P = .575 for CBT1; P = .150 for CBT2). CONCLUSIONS: Normal peripheral retinas generally show granular background fluorescence, with or without a mottled fluorescent band. PMID- 27693445 TI - Reversal of cardiac vagal effects of physostigmine by adjunctive muscarinic blockade. AB - Pre-treatment with reversible acetylcholinesterase (AChE) inhibitors is an effective strategy for reducing lethality following organophosphate nerve agent exposure. AChE inhibition may have unwanted cardiac side effects, which could be negated by adjunctive anti-cholinergic therapy. The aims of the present study were to examine the concentration-dependent effects of physostigmine on cardiac responses to vagus nerve stimulation (VNS), to test whether adjunctive treatment with hyoscine can reverse these effects and to assess the functional interaction and electrophysiological consequences of a combined pre-treatment. Studies were performed in an isolated innervated rabbit heart preparation. The reduction in heart rate with VNS was augmented by physostigmine (1-1000nmol/L), in a concentration-dependent manner - with an EC50 of 19nmol/L. Hyoscine was shown to be effective at blocking the cardiac responses to VNS with an IC50 of 11nmol/L. With concomitant perfusion of physostigmine, the concentration-response curve for hyoscine was shifted downward and to the right, increasing the concentration of hyoscine required to normalise (to control values) the effects of physostigmine on heart rate. At the lowest concentration of hyoscine examined (1nmol/L) a modest potentiation of heart rate response to VNS (+15+/-3%) was observed. We found no evidence of cardiac dysfunction or severe electrophysiological abnormalities with either physostigmine or hyoscine alone, or as a combined drug therapy. The main finding of this study is that hyoscine, at concentrations greater than 10-8M, is effective at reversing the functional effects of physostigmine on the heart. However, low-concentrations of hyoscine may augment cardiac parasympathetic control. PMID- 27693446 TI - Propylparaben reduces the excitability of hippocampal neurons by blocking sodium channels. AB - Propylparaben (PPB) is an antimicrobial preservative widely used in food, cosmetics, and pharmaceutics. Virtual screening methodologies predicted anticonvulsant activity of PPB that was confirmed in vivo. Thus, we explored the effects of PPB on the excitability of hippocampal neurons by using standard patch clamp techniques. Bath perfusion of PPB reduced the fast-inactivating sodium current (INa) amplitude, causing a hyperpolarizing shift in the inactivation curve of the INa, and markedly delayed the sodium channel recovery from the inactivation state. Also, PPB effectively suppressed the riluzole-sensitive, persistent sodium current (INaP). PPB perfusion also modified the action potential kinetics, and higher concentrations of PPB suppressed the spike activity. Nevertheless, the modulatory effects of PPB did not occur when PPB was internally applied by whole-cell dialysis. These results indicate that PPB reduces the excitability of CA1 pyramidal neurons by modulating voltage-dependent sodium channels. The mechanistic basis of this effect is a marked delay in the recovery from inactivation state of the voltage-sensitive sodium channels. Our results indicate that similar to local anesthetics and anticonvulsant drugs that act on sodium channels, PPB acts in a use-dependent manner. PMID- 27693447 TI - A Randomized Study of Intraoperative Autologous Retropubic Urethral Sling on Urinary Control after Robotic Assisted Radical Prostatectomy. AB - PURPOSE: We evaluated whether placement of a retropubic urethral sling fashioned from autologous vas deferens during robotic assisted radical prostatectomy would improve recovery of continence. MATERIALS AND METHODS: In a phase 2, single blind trial age stratified patients were randomized to undergo robotic assisted radical prostatectomy by multiple surgeons with or without sling placement. The outcomes were complete continence (0 urinary pads of any type) and near continence (0, an occasional or 1 pad per day) at 6 months, which was assessed by the Fisher exact test and logistic regression. The Kaplan-Meier method and the log rank test were used to evaluate time to continence. EPIC-UIN (Expanded Prostate Cancer Index Composite-Urinary Inventory) and I-PSS (International Prostate Symptom Score) 1, 3 and 6 months after catheter removal were evaluated by mixed models for repeated measures. RESULTS: Of 203 patients who were recruited 95 and 100 were randomized to undergo sling and no sling placement, respectively, and completed postoperative interviews. Six months after surgery the proportions reporting complete and near continence (66% and 87%, respectively) and times to complete and near continence were similar in the groups. Younger age was associated with a higher likelihood of complete continence (OR 1.74 per decreasing 5-year interval, 95% CI 1.23-2.48, p <0.01) and near continence (OR 2.18 per decreasing 5-year interval, 95% CI 1.21-3.92, p <0.01) adjusting for clinical, urinary and surgical factors. Adjusted EPIC-UIN and I-PSS scores changed with time but did not differ between the groups. No serious adverse events were observed. CONCLUSIONS: This trial failed to demonstrate a benefit of autologous urethral sling placement at robotic assisted radical prostatectomy on early return of continence at 6 months. Continence was related to patient age in adjusted models. PMID- 27693448 TI - PTEN Loss in Gleason Score 3 + 4 = 7 Prostate Biopsies is Associated with Nonorgan Confined Disease at Radical Prostatectomy. AB - PURPOSE: Men with intermediate risk prostate cancer have widely variable outcomes. Some suggest that active surveillance or less invasive therapies (brachytherapy or focal therapy) may be appropriate for some men with Gleason score 3 + 4 = 7 disease. Molecular markers may help further distinguish prostate cancers with aggressive behavior. We tested whether loss of the PTEN (phosphatase and tensin homolog) tumor suppressor in 3 + 4 = 7 tumor biopsies is associated with adverse pathology at prostatectomy. MATERIALS AND METHODS: We queried prostate needle biopsies from 2000 to 2014 with a maximum Gleason score of 3 + 4 = 7 followed by prostatectomy. A total of 260 cases had PTEN status evaluable by clinical grade immunohistochemistry. Biopsy PTEN status was correlated with preoperative and postoperative clinicopathological parameters. RESULTS: PTEN loss was detected in 27% of 3 + 4 = 7 biopsies. Loss of PTEN was less common in tumors of African American men compared to European American men (9% vs 31%, p = 0.002). At prostatectomy, tumors with PTEN loss were more likely to show nonorgan confined disease compared to those with PTEN intact (52% vs 27%, p <0.001). In logistic regression models including age, race, prostate specific antigen, clinical stage and biopsy tumor involvement, PTEN loss at biopsy remained significantly associated with an increased risk of nonorgan confined disease (HR 2.46, 95% CI 1.34-4.49, p = 0.004). On ROC analysis, the AUC for models including prostate specific antigen and clinical stage was increased from 0.61 to 0.67 upon inclusion of PTEN status. CONCLUSIONS: PTEN loss in a Gleason score 3 + 4 = 7 biopsy is independently associated with an increased risk of nonorgan confined disease at prostatectomy. It adds to the preoperative parameters commonly used to predict pathological stage. PMID- 27693449 TI - The Economic Implications of a Reusable Flexible Digital Ureteroscope: A Cost Benefit Analysis. AB - PURPOSE: Questions remain regarding the durability and longevity of flexible ureteroscopes. The objective of this study was to estimate the potential economic benefits of single use, flexible digital ureteroscopes compared to our recent experience with reusable flexible digital ureteroscopes using cost-benefit analysis. MATERIALS AND METHODS: Ureteroscopic procedures were prospectively recorded over the 12-month period of February 2014 to February 2015. All flexible ureteroscopies were performed using Flex XC digital ureteroscopes (Karl Storz Endoscopy-America, El Segundo, California). Cost assessment was based on the original purchasing cost and repair-exchange fees divided by the number of cases. An algorithm was created to include per case reprocessing costs and calculate the benefit-to-cost ratio. This cost was compared to potential costs of the LithoVueTM, a single use digital ureteroscope. RESULTS: In 160 cases a flexible reusable ureteroscope was used. There was damage to 11 ureteroscopes during this time with an average of 12.5 cases to failure. Excluding original purchasing costs, the cost analysis revealed an amortized cost of $848.10 per use. After 99 ureteroscope cases the cost-benefit analysis favored reusable ureteroscopes compared to disposable ureteroscopes. CONCLUSIONS: Digital ureteroscopes are the latest trend in the evolution of endourology. It appears that a disposable ureteroscope may be cost beneficial at centers with a lower case volume per year. However, institutions with a high volume of cases may find reusable ureteroscopes cost beneficial. PMID- 27693450 TI - Properties of the 4-Kallikrein Panel Outside the Diagnostic Gray Zone: Meta Analysis of Patients with Positive Digital Rectal Examination or Prostate Specific Antigen 10 ng/ml and Above. AB - PURPOSE: The 4-kallikrein panel, commercially available as the 4KscoreTM, is a reflex test for prostate cancer early detection that has been extensively validated in multiple international cohorts. It has been suggested that use of such reflex tests be limited to those with prostate specific antigen less than 10 ng/ml and negative digital rectal examination. We aimed to determine the value of the panel in men outside this "diagnostic gray zone." MATERIALS AND METHODS: We performed an individual patient data meta-analysis using data from prior studies on the 4-kallikrein panel. We calculated the properties of the panel for predicting high grade (Gleason 7+) cancer in a subgroup of men with either positive digital rectal examination or prostate specific antigen 10 to 25 ng/ml. RESULTS: A total 2,891 men from 8 cohorts were included. An important proportion of patients, including 32% in the United States validation study, had prostate specific antigen 10 to 25 ng/ml or a positive digital rectal examination. For men with prostate specific antigen 10 to 25 ng/ml the fixed-effects estimate for the discrimination of the kallikrein model was 0.84 vs 0.69 for the base model (difference 0.128, 95% CI 0.098-0.159). In the positive digital rectal examination group discrimination was 0.82 vs 0.72 (difference 0.092, 95% CI 0.069 0.115). Decision analysis showed a clinical net benefit for use of the panel in this subgroup with a reduction in biopsy rates of about 20% and only a small number of high grade cancers missed, or fewer than 3% of those not biopsied. CONCLUSIONS: The use of the kallikrein panel in men with a positive digital rectal examination or prostate specific antigen 10 to 25 ng/ml is justified. PMID- 27693451 TI - Crosstalk between the vitamin D receptor (VDR) and miR-214 in regulating SuFu, a hedgehog pathway inhibitor in breast cancer cells. AB - The vitamin D receptor (VDR), and its ligand 1alpha,25-dihydroxyvitamin D3 (1,25D3) prevent breast cancer development and progression, yet the molecular mechanisms governing this are unclear. MicroRNAs (miRNAs) on the other hand, promote or inhibit breast cancer growth. To understand how VDR regulates miRNAs, we compared miRNA expression of wild-type (WT) and VDR knockout (VDRKO) breast cancer cells by a Mouse Breast Cancer miRNA PCR array. Compared to VDR WT cells, expressions of miR-214, miR-199a-3p and miR-199a-5p of the miR-199a/miR-214 cluster were 42, 15, and 10 fold higher in VDRKO cells respectively. Overexpression of VDR in breast cancer cells reduced the miR-199a/miR-214 cluster expression by 30%. VDR status also negatively correlated with Dnm3os expression, a non-coding RNA transcript of the dynamin-3 gene encoding the miR-199a/miR-214 cluster, suggesting that VDR represses this cluster through Dnm3os. Conversely, overexpression of miR-214 in MCF-7 and T47D cells antagonized VDR mediated signaling. Furthermore, there was a positive correlation between VDR status and the expression of Suppressor of fused gene (SuFu), a hedgehog pathway inhibitor. miR-214 on the other hand suppressed SuFu protein expression. These findings suggest a crosstalk between VDR and miR-214 in regulating hedgehog signaling in breast cancer cells, providing new therapies for breast cancer. PMID- 27693452 TI - Relative expression of the p75 neurotrophin receptor, tyrosine receptor kinase A, and insulin receptor in SH-SY5Y neuroblastoma cells and hippocampi from Alzheimer's disease patients. AB - We have previously shown in SH-SY5Y human neuroblastoma cells that the expressions of basal (75 kDa) and high molecular weight (HMW; 85 kDa) isoforms of the p75 neurotrophic receptor (p75NTR) are stimulated by amyloid-beta peptide1-42 oligomers (AbetaOs) via the insulin-like growth factor-1 receptor (IGF-1R). On the other hand, it is known that AbetaOs inhibit insulin receptor (IR) signaling. The purpose of the present study was to determine the involvement of IR signaling in the regulation of p75 neurotrophin receptor (p75NTR) protein isoform expression in cultured SH-SY5Y cells and in hippocampi from late-stage human Alzheimer's disease (AD) brains. Interestingly, insulin induced the expression of basal and HMW p75NTR isoforms in SH-SY5Y cells, suggesting the presence of cross talk between the IR and IGF-1R for the regulation of p75NTR expression. Reducing IR signaling with an IR kinase inhibitor (AG 1024) or IR-targeted siRNAs increased HMW p75NTR expression and reduced tyrosine receptor kinase-A (Trk-A) expression as well as postsynaptic density protein 95 (PSD95) expression in SH SY5Y cells. Both basal and HMW p75NTR isoforms were increased in the hippocampi of post-mortem late-stage human AD brains (relative to non-AD brains), and the protein expression of HMW p75NTR was negatively associated with Trk-A expression, PSD95 expression, and IR expression. Thus, increased p75NTR expression, specifically an increased p75NTR-to-Trk-A ratio, is likely to play a role in synaptic loss and neuronal cell death in late-stage AD. Collectively, these findings suggest that increased expression of the p75NTR due to IR signaling inhibition by AbetaOs might be involved in the pathology of AD. PMID- 27693453 TI - Development of a neuroprotective potential algorithm for medicinal plants. AB - Medicinal plants are promising candidates for Alzheimer's disease (AD) research but there is lack of systematic algorithms and procedures to guide their selection and evaluation. Herein, we developed a Neuroprotective Potential Algorithm (NPA) by evaluating twenty-three standardized and chemically characterized Ayurvedic medicinal plant extracts in a panel of bioassays targeting oxidative stress, carbonyl stress, protein glycation, amyloid beta (Abeta) fibrillation, acetylcholinesterase (AChE) inhibition, and neuroinflammation. The twenty-three herbal extracts were initially evaluated for: 1) total polyphenol content (Folin-Ciocalteu assay), 2) free radical scavenging capacity (DPPH assay), 3) ferric reducing antioxidant power (FRAP assay), 4) reactive carbonyl species scavenging capacity (methylglyoxal trapping assay), 5) anti-glycative effects (BSA-fructose, and BSA-methylglyoxal assays) and, 6) anti Abeta fibrillation effects (thioflavin-T assay). Based on assigned index scores from the initial screening, twelve extracts with a cumulative NPA score >=40 were selected for further evaluation for their: 1) inhibitory effects on AChE activity, 2) in vitro anti-inflammatory effects on murine BV-2 microglial cells (Griess assay measuring levels of lipopolysaccharide-induced nitric oxide species), and 3) in vivo neuroprotective effects on Caenorhabditis elegans post induction of Abeta1-42 induced neurotoxicity and paralysis. Among these, four extracts had a cumulative NPA score >=60 including Phyllanthus emblica (amla; Indian gooseberry), Mucuna pruriens (velvet bean), Punica granatum (pomegranate) and Curcuma longa (turmeric; curcumin). These extracts also showed protective effects on H2O2 induced cytotoxicity in differentiated cholinergic human neuronal SH-SY5Y and murine BV-2 microglial cells and reduced tau protein levels in the SH SY5Y neuronal cells. While published animal data support the neuroprotective effects of several of these Ayurvedic medicinal plant extracts, some remain unexplored for their anti-AD potential. Therefore, the NPA may be utilized, in part, as a strategy to help guide the selection of promising medicinal plant candidates for future AD-based research using animal models. PMID- 27693454 TI - Decorin interacting network: A comprehensive analysis of decorin-binding partners and their versatile functions. AB - Decorin, a prototype small leucine-rich proteoglycan, regulates a vast array of cellular processes including collagen fibrillogenesis, wound repair, angiostasis, tumor growth, and autophagy. This functional versatility arises from a wide array of decorin/protein interactions also including interactions with its single glycosaminoglycan side chain. The decorin-binding partners encompass numerous categories ranging from extracellular matrix molecules to cell surface receptors to growth factors and enzymes. Despite the diversity of the decorin interacting network, two main roles emerge as prominent themes in decorin function: maintenance of cellular structure and outside-in signaling, culminating in anti tumorigenic effects. Here we present contemporary knowledge regarding the decorin interacting network and discuss in detail the biological relevance of these pleiotropic interactions, some of which could be targeted by therapeutic interventions. PMID- 27693455 TI - Targeting cancer cells through antibiotics-induced mitochondrial dysfunction requires autophagy inhibition. AB - A significant part of current research studies utilizes various cellular models which imply specific antibiotics-containing media as well as antibiotics used for clonal selection or promoter de/activation. With the great success of developing such tools, mitochondria, once originated from bacteria, can be effectively targeted by antibiotics. For that reason, some studies propose antibiotics targeting of mitochondria as part of anticancer therapy. Here, we have focused on the effects of various classes of antibiotics on mitochondria in cancer and non cancer cells and demonlow mitochondrial membrane potential, reduced ATP production, altered morphology and lowered respiration rate which altogether suggested mitochondrial dysfunction (MDF). This was in parallel with increased level of reactive oxygen species (ROS) and decreased activity of mitochondrial respiration complexes. However, both survival and repopulation capacity of cancer cells was not significantly affected by the antibiotics, perhaps due to a glycolytic shift or activated autophagy. In turn, simultaneous inhibition of autophagy and treatment with antibiotics largely reduced tumorigenic properties of cancer cells suggesting potential strategy for anticancer therapy. PMID- 27693456 TI - Targeting miRNAs associated with surface expression of death receptors to modulate TRAIL resistance in breast cancer. AB - Tumor necrosis factor related apoptosis-inducing ligand (TRAIL) is capable of inducing apoptosis upon engagement of its death receptors (DRs) 4 and 5. TRAIL therapy has garnered intense interest as one of the most promising agents for cancer therapy, for its selective induction of tumor-cell apoptosis while low toxicity to most normal cells. However, a variety of breast cancer cell lines could be resistant to TRAIL-induced apoptosis. Absence of DR4 and DR5 on the breast cancer cell surface has been proposed to be critically involved in resistance to TRAIL and its agonistic antibodies. Moreover, endocytosis and autophagy in breast cancer cells could induce TRAIL resistance through downregulation of surface DR4/5. MicroRNAs (miRNAs), as endogenously expressed small non-coding RNAs, function as regulators of gene expression and involve tremendous biological processes including drug resistance. In this review, we highlight recent advances in the functional role of miRNAs in endocytosis and autophagy pathways. This review aims to present that, through regulation of critical molecules involved in autophagy and endocytosis, miRNAs could lead to mislocalization of DR4/5 in breast cancer cells and therefore play an important role in TRAIL-mediated apoptosis and TRAIL resistance. PMID- 27693458 TI - 2-Methoxy-5((3,4,5-trimethosyphenyl)seleninyl) phenol inhibits MDM2 and induces apoptosis in breast cancer cells through a p53-independent pathway. AB - 2-Methoxy-5((3,4,5-trimethosyphenyl)seleninyl) phenol (SQ) is a novel synthesized combretastatin A-4 (CA-4) analog that can be classified as a microtubule inhibitor. Our previous study demonstrated that SQ induced G2/M phase arrest and promoted apoptosis progression in breast cancer cells. In the present study, we found that SQ dissociated the MDM2-p53 complex and directly induced MDM2 degradation through the ubiquitin-dependent proteasome pathway in MCF-7 and MDA MB-231 cells. Further, p53 was activated by SQ through regulation of its transcription, translation, and post-translation modification. More specifically, we demonstrated that SQ induced caspase-dependent but p53-independent apoptosis, and this apoptosis is associated with the inhibition of MDM2. We also showed that SQ exhibited superior in vivo efficacy and low toxicity than CA-4. The immunofluorescence histochemistry study indicated that SQ also inhibited MDM2 expression in vivo. In summary, we report for the first time that SQ shows excellent anti-breast cancer activity in vivo and in vitro and induces p53 independent apoptosis, which is associated with MDM2 inhibition. Therefore, the novel compound SQ has potential for therapeutic treatment of both wild-type and mutant p53 breast cancer. PMID- 27693457 TI - Compromized DNA repair as a basis for identification of cancer radiotherapy patients with extreme radiosensitivity. AB - A small percentage of cancer radiotherapy patients develop abnormally severe side effects as a consequence of intrinsic radiosensitivity. We analysed the gamma H2AX response to ex-vivo irradiation of peripheral blood lymphocytes (PBL) and plucked eyebrow hair follicles from 16 patients who developed severe late radiation toxicity following radiotherapy, and 12 matched control patients. Longer retention of the gamma-H2AX signal and lower colocalization efficiency of repair factors in over-responding patients confirmed that DNA repair in these individuals was compromised. Five of the radiosensitive patients harboured LoF mutations in DNA repair genes. An extensive range of quantitative parameters of the gamma-H2AX response were studied with the objective to establish a predictor for radiosensitivity status. The most powerful predictor was the combination of the fraction of the unrepairable component of gamma-H2AX foci and repair rate in PBL, both derived from non-linear regression analysis of foci repair kinetics. We introduce a visual representation of radiosensitivity status that allocates a position for each patient on a two-dimensional "radiosensitivity map". This analytical approach provides the basis for larger prospective studies to further refine the algorithm, ultimately to triage capability. PMID- 27693459 TI - Breast cancer-secreted miR-939 downregulates VE-cadherin and destroys the barrier function of endothelial monolayers. AB - Exosomes-secreted microRNAs play an important role in metastatic spread. During this process breast cancer cells acquire the ability to transmigrate through blood vessels by inducing changes in the endothelial barrier. We focused on miR 939 that is predicted to target VE-cadherin, a component of adherens junction involved in vessel permeability. By in silico analysis miR-939 was found highly expressed in the basal-like tumor subtypes and in our cohort of 63 triple negative breast cancers (TNBCs) its expression significantly interacted with lymph node status in predicting disease-free survival probability. We demonstrated, in vitro, that miR-939 directly targets VE-cadherin leading to an increase in HUVECs monolayer permeability. MDA-MB-231 cells transfected with a miR-939 mimic, released miR-939 in exosomes that, once internalized in endothelial cells, favored trans-endothelial migration of MDA-MB-231-GFP cells by the disruption of the endothelial barrier. Notably, when up taken in endothelial cells exosomes caused VE-cadherin down-regulation specifically through miR-939 as we demonstrated by inhibiting miR-939 expression in exosomes-releasing TNBC cells. Together, our data indentify an extracellular pro-tumorigenic role for tumor-derived, exosome-associated miR-939 that can explain its association with worse prognosis in TNBCs. PMID- 27693460 TI - Vascular mimicry formation is promoted by paracrine TGF-beta and SDF1 of cancer associated fibroblasts and inhibited by miR-101 in hepatocellular carcinoma. AB - Vascular mimicry (VM) describes the phenomenon that tumor cells but not endothelial cells form vascular-like channels, which provide blood perfusion for tumor tissues. VM is associated with tumor growth, metastasis and worse survival of different cancers. The mechanisms of VM formation remain largely unknown. We showed that the conditioned medium of cancer-associated fibroblast (CM-CAF) promoted tumor cells to form capillary-like structure in vitro. Consistently, co implantation of CAFs with tumor cells significantly enhanced VM formation in mouse xenografts, and higher amount of CAFs was found in VM+ human HCC tissues compared to VM- ones. However, the CM-CAF-promoted VM formation was attenuated when TGF-beta or SDF1 signaling was abrogated. Similar to CM-CAF, recombinant TGF beta1 and SDF1 induced VM formation. We further disclosed that the CAF-secreted TGF-beta and SDF1 enhanced the expression of VE-cadherin, MMP2 and laminin5gamma2 via TGF-betaR1 and CXCR4 in tumor cells, thereby promoted VM formation. Moreover, tumor cells with high activity of self-sustaining TGF-beta signaling displayed strong capability of VM formation. Subsequent investigations showed that miR-101, which was down-regulated in both tumor cells and CAFs, suppressed the CAF promoted VM formation in vitro and in vivo. Gain- and loss-of-function analyses revealed that miR-101 attenuated TGF-beta signaling transduction by targeting TGF betaR1 and Smad2 in tumor cells, and simultaneously abrogated SDF1 signaling by suppressing SDF1 expression in CAFs and inhibiting VE-cadherin expression in tumor cells. Our findings suggest that the miR-101-TGF-beta/SDF1-VE cadherin/MMP2/LAMC2 networks regulate VM formation and represent the potential targets for cancer therapy. PMID- 27693461 TI - Inhibition of ATR-dependent feedback activation of Chk1 sensitises cancer cells to Chk1 inhibitor monotherapy. AB - The Chk1 and ATR kinases are critical mediators of the DNA damage response pathway and help protect cancer cells from endogenous and oncogene induced replication stress. Inhibitors of both kinases are currently being evaluated in clinical trials. Chk1 inhibition with V158411 increases DNA damage and activates the ATR, ATM and DNA-PKcs dependent DNA damage response pathways. Inhibiting ATR, ATM and/or DNA-PKcs has the potential to increase the therapeutic activity of Chk1 inhibitors. ATR inhibition but not ATM or DNA-PKcs inhibition potentiated the cytotoxicity of V158411 in p53 mutant and wild type human cancer cell lines. This increased cytotoxicity correlated with increased nuclear DNA damage and replication stress in a dose and time dependent manner. gammaH2AX induction following Chk1 inhibition protected cells from caspase-dependent apoptosis. Inhibition of ATR increased Chk1 inhibitor induced cell death independently of caspase activation. The effect of ATR, ATM and/or DNA-PK inhibition on Chk1 inhibitor induced replication stress was dependent on the concentration of Chk1 inhibitor. ATR inhibition potentiated Chk1 inhibitor induced replication stress and cytotoxicity via the abrogation of ATR-dependent feedback activation of Chk1 induced by Chk1 inhibitor generated replication stress. This study suggests that combining an ATR inhibitor to lower the threshold by which a Chk1 inhibitor induces replication stress, DNA damage and tumour cell death in a wide range of cancer types may be a useful clinical approach. PMID- 27693462 TI - Ghrelin O-acyltransferase (GOAT) enzyme is overexpressed in prostate cancer, and its levels are associated with patient's metabolic status: Potential value as a non-invasive biomarker. AB - Ghrelin-O-acyltransferase (GOAT) is the key enzyme regulating ghrelin activity, and has been proposed as a potential therapeutic target for obesity/diabetes and as a biomarker in some endocrine-related cancers. However, GOAT presence and putative role in prostate-cancer (PCa) is largely unknown. Here, we demonstrate, for the first time, that GOAT is overexpressed (mRNA/protein-level) in prostatic tissues (n = 52) and plasma/urine-samples (n = 85) of PCa-patients, compared with matched controls [healthy prostate tissues (n = 12) and plasma/urine-samples from BMI-matched controls (n = 28), respectively]. Interestingly, GOAT levels in PCa patients correlated with aggressiveness and metabolic conditions (i.e. diabetes). Actually, GOAT expression was regulated by metabolic inputs (i.e. In1-ghrelin, insulin/IGF-I) in cultured normal prostate cells and PCa-cell lines. Importantly, ROC-curve analysis unveiled a valuable diagnostic potential for GOAT to discriminate PCa at the tissue/plasma/urine-level with high sensitivity/specificity, particularly in non-diabetic individuals. Moreover, we discovered that GOAT is secreted by PCa-cells, and that its levels are higher in urine samples from a stimulated post-massage vs. pre-massage prostate-test. In conclusion, plasmatic GOAT levels exhibit high specificity/sensitivity to predict PCa-presence compared with other PCa-biomarkers, especially in non-diabetic individuals, suggesting that GOAT holds potential as a novel non-invasive PCa biomarker. PMID- 27693464 TI - Predictive value of sICAM-1 and sVCAM-1 as biomarkers of affective temperaments in healthy young adults. AB - BACKGROUND: Affective temperaments are intermediate phenotypes for major affective disorders and are reported to have a neuroimmune etiopathogenesis. Here we investigated the role of soluble intercellular cell adhesion molecule-1 (sICAM 1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) in affective temperaments and mood symptoms in healthy adults. METHODS: Healthy adults (n=94) were screened for psychiatric disorders using the nonpatient version of the Structured Clinical Interview for DSM-IV-I and II. Subjects with medical conditions associated with changes in inflammatory response were excluded, deriving the final sample (n=68). Affective temperaments were evaluated with Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A). State mood symptoms were assessed using the Young Mania Rating Scale and Montgomery-Asberg Depression Rating Scale. Serum sICAM-1 and sVCAM-1 levels were measured using enzyme-linked immunosorbent assay. RESULTS: After adjusting for confounders (age, gender, BMI, and smoking habits), a high negative correlation between depressive and irritable temperament TEMPS-A scores and sVCAM 1 levels was detected. Although we identified no association between sICAM-1 levels and affective temperament scores, sICAM-1 was related to the state severity of manic symptoms. In a multiple linear regression model, sVCAM-1 remained a significant predictor of depressive but not irritable temperament scores. LIMITATIONS: The temperaments were estimated on the basis of self-report questionnaire. CONCLUSIONS: Our findings suggest that sVCAM-1 is related to affective temperaments, and it is a trait marker for liability to mood disorders. This relationship between alterations in cellular adhesion and affective temperament may be important for vulnerability to affective disorders.

Disord. 182 (2015) 82-90]. PMID- 27693463 TI - Preservation of myocardial fatty acid oxidation prevents diastolic dysfunction in mice subjected to angiotensin II infusion. AB - RATIONALE: Diastolic dysfunction is a common feature in many heart failure patients with preserved ejection fraction and has been associated with altered myocardial metabolism in hypertensive and diabetic patients. Therefore, metabolic interventions to improve diastolic function are warranted. In mice with a germline cardiac-specific deletion of acetyl CoA carboxylase 2 (ACC2), systolic dysfunction induced by pressure-overload was prevented by maintaining cardiac fatty acid oxidation (FAO). However, it has not been evaluated whether this strategy would prevent the development of diastolic dysfunction in the adult heart. OBJECTIVE: To test the hypothesis that augmenting cardiac FAO is protective against angiotensin II (AngII)-induced diastolic dysfunction in an adult mouse heart. METHODS AND RESULTS: We generated a mouse model to induce cardiac-specific deletion of ACC2 in adult mice. Tamoxifen treatment (20mg/kg/day for 5days) was sufficient to delete ACC2 protein and increase cardiac FAO by 50% in ACC2 flox/flox-MerCreMer+ mice (iKO). After 4weeks of AngII (1.1mg/kg/day), delivered by osmotic mini-pumps, iKO mice showed normalized E/E' and E'/A' ratios compared to AngII treated controls (CON). The prevention of diastolic dysfunction in iKO-AngII was accompanied by maintained FAO and reduced glycolysis and anaplerosis. Furthermore, iKO-AngII hearts had a~50% attenuation of cardiac hypertrophy and fibrosis compared to CON. In addition, maintenance of FAO in iKO hearts suppressed AngII-associated increases in oxidative stress and sustained mitochondrial respiratory complex activities. CONCLUSION: These data demonstrate that impaired FAO is a contributor to the development of diastolic dysfunction induced by AngII. Maintenance of FAO in this model leads to an attenuation of hypertrophy, reduces fibrosis, suppresses increases in oxidative stress, and maintains mitochondrial function. Therefore, targeting mitochondrial FAO is a promising therapeutic strategy for the treatment of diastolic dysfunction. PMID- 27693467 TI - Expected pairwise congruence among gene trees under the coalescent model. AB - Although it is widely appreciated that gene trees may differ from the overall species tree and from one another due to various evolutionary processes (e.g., incomplete lineage sorting (ILS), horizontal gene transfer, etc.), the extent of this incongruence is rarely quantified and discussed. Here we consider the expected amount of incongruence arising from ILS, as modeled by the coalescent process. In particular, we compute the probability that two gene trees randomly sampled from the same species tree agree with one another as well as the distribution of the Robinson-Foulds distance between them, for species trees with three to eight taxa. We demonstrate that, as expected under the coalescent model, the amount of discordance is affected by species tree-specific factors such as speciation times and effective population sizes for the species under consideration. Our results highlight the fact that substantial discordance may occur, even when the number of species is very small, which has implications both for larger taxon samples and for any method that uses estimated gene trees as the basis for further statistical inference. The amount of incongruence is substantial enough that such methods may need to be modified to account for variability in the underlying gene trees. PMID- 27693466 TI - Cost-effectiveness of brexpiprazole adjunctive treatment for major depressive disorder. AB - BACKGROUND: Major depressive disorder (MDD) is a debilitating psychiatric illness with a high cost burden. This analysis evaluates the cost-effectiveness of adjunctive brexpiprazole versus comparator branded adjunctive treatment for MDD and background antidepressant therapy (ADT) alone from a US payer perspective. METHODS: An economic model was developed to assess the cost-effectiveness of brexpiprazole versus comparator adjunctive treatment and ADT alone on total direct medical costs using a 6-week cycle time frame for a total of 48 weeks, with treatment response and remission as primary outcomes. The model consisted of 3 parts, 1 to represent the acute treatment phase and 2 to represent the maintenance stage. RESULTS: In the base-case analysis, brexpiprazole as reference treatment resulted in cost per additional responder ranging from $19,442-$48,745 and cost per additional remitter ranging from $27,196-$71,839 versus comparator treatments over 48 weeks. Sensitivity analyses showed treatment with brexpiprazole was more costly, but more clinically effective in all probabilistic simulations. LIMITATIONS: This representation of disease natural history over 48 weeks may not account for all possible health states. Resource utilization on treatment was estimated using the resource use data from previous trials, and may overestimate medical costs compared to the real-world setting. Treatment comparators were limited to branded therapies, and head-to-head studies were not available to obtain data inputs. CONCLUSION: Compared to other branded adjunctive therapies, brexpiprazole increases response and remission at 6 weeks; medical care cost savings were observed with the use of brexpiprazole. These findings may assist clinicians and formulary decision makers when selecting treatment for MDD. PMID- 27693468 TI - Parkin regulates lipopolysaccharide-induced proinflammatory responses in acute lung injury. AB - The acute respiratory distress syndrome (ARDS) is a serious condition resulting from direct or indirect lung injury that is associated with high mortality and morbidity. A key biological event in the pathogenesis of the acute lung injury (ALI) that causes acute respiratory distress syndrome is activation of the lung endothelium cells (ECs), which is triggered by a variety of inflammatory insults leading to barrier disruption and excessive accumulation of neutrophils. Recently, we demonstrated that imatinib protects against lipopolysaccharide (LPS) induced EC activation by inhibiting c-Abl kinase. In the present study, we explored the role of parkin, a novel c-Abl substrate, in ALI. Parkin is an E3 ubiquitin ligase originally characterized in the pathogenesis of Parkinson disease; however, its potential role in acute inflammatory processes and lung EC function remains largely unknown. Using parkin deficient (PARK2-/-) mice, we now demonstrate that parkin mediates LPS-induced ALI. After LPS, PARK2-/- mice have reduced total protein and cell levels in bronchoalveolar lavage (BAL) compared to wild type. Moreover, in LPS-treated PARK2-/- lungs, the sequestration and activation of neutrophils and release of inflammatory cytokines (interleukin 6 [IL-6], tumor necrosis factor alpha [TNF-alpha]) are significantly reduced. The BAL levels of soluble VCAM-1 and ICAM-1 are also decreased in LPS-treated PARK2-/ mice compared to wild type. In cultured human lung endothelial cells, downregulation of parkin by small interfering RNA decreases LPS-induced VCAM-1 expression, IL-8 and IL-6 secretion, and NF-kB phosphorylation. These results suggest a previously unidentified role of parkin in mediating endotoxin-induced endothelial proinflammatory signaling and indicate that it may play a critical role in acute inflammation.

AB - Mitochondrial complex I is a 1MDa membrane protein complex with a central role in aerobic energy metabolism. The bioenergetic core functions are executed by 14 central subunits that are conserved from bacteria to man. Despite recent progress in structure determination, our understanding of the function of the ~30 accessory subunits associated with the mitochondrial complex is still limited. We have investigated the structure of complex I from the aerobic yeast Yarrowia lipolytica by cryo-electron microscopy. Our density map at 7.9A resolution closely matches the 3.6-3.9A X-ray structure of the Yarrowia lipolytica complex. However, the cryo-EM map indicated an additional subunit on the side of the matrix arm above the membrane surface, pointing away from the membrane arm. The density, which is not present in any previously described complex I structure and occurs in about 20 % of the particles, was identified as the accessory sulfur transferase subunit ST1. The Yarrowia lipolytica complex I preparation is active in generating H2S from the cysteine derivative 3-mercaptopyruvate, catalyzed by ST1. We thus provide evidence for a link between respiratory complex I and mitochondrial sulfur metabolism. PMID- 27693470 TI - Head movement compensation and multi-modal event detection in eye-tracking data for unconstrained head movements. AB - BACKGROUND: The complexity of analyzing eye-tracking signals increases as eye trackers become more mobile. The signals from a mobile eye-tracker are recorded in relation to the head coordinate system and when the head and body move, the recorded eye-tracking signal is influenced by these movements, which render the subsequent event detection difficult. NEW METHOD: The purpose of the present paper is to develop a method that performs robust event detection in signals recorded using a mobile eye-tracker. The proposed method performs compensation of head movements recorded using an inertial measurement unit and employs a multi modal event detection algorithm. The event detection algorithm is based on the head compensated eye-tracking signal combined with information about detected objects extracted from the scene camera of the mobile eye-tracker. RESULTS: The method is evaluated when participants are seated 2.6m in front of a big screen, and is therefore only valid for distant targets. The proposed method for head compensation decreases the standard deviation during intervals of fixations from 8 degrees to 3.3 degrees for eye-tracking signals recorded during large head movements. COMPARISON WITH EXISTING METHODS: The multi-modal event detection algorithm outperforms both an existing algorithm (I-VDT) and the built-in algorithm of the mobile eye-tracker with an average balanced accuracy, calculated over all types of eye movements, of 0.90, compared to 0.85 and 0.75, respectively for the compared algorithms. CONCLUSIONS: The proposed event detector that combines head movement compensation and information regarding detected objects in the scene video enables for improved classification of events in mobile eye tracking data. PMID- 27693471 TI - Serine racemase inhibition induces nitric oxide-mediated neurovascular protection during cerebral ischemia. AB - There are no effective neuroprotectant drugs for acute cerebral ischemia. Serine racemase (SR) synthesizes d-serine, which is involved in N-methyl-d-aspartate (NMDA) receptor-induced neurotoxicity. Recently, SR deletion was reported to protect against focal cerebral ischemia. However, regulatory mechanisms controlling SR-activity in the neurovascular unit (NVU) during cerebral ischemia remain to be clarified. We investigated the effects of SR inhibition on neurovascular protection after ischemia. The SR inhibitor phenazine methosulfate (PMS) alleviated neuronal damage in an ex vivo ischemic model (oxygen glucose deprivation [OGD]) using primary neuronal cultures, and in an in vivo mouse model of ischemia (middle cerebral artery occlusion [MCAO]). Ischemic preconditioning (IP) and PMS-treatment inhibited SR phosphorylation after ischemia ex vivo. In addition, SR phosphorylation after MCAO was also decreased in PMS-treated mice. Reductions in regional cerebral blood flow (CBF) after MCAO were improved by administration of PMS. Treatment with PMS increased phosphorylation of endothelial nitric oxide synthase (eNOS) in the ischemic core and penumbra region. In neuron-endothelial cell co-cultures, PMS promoted nitric oxide production after OGD. These findings indicate that SR inhibition acts as a neuroprotectant in the NVU and ameliorant of CBF abnormalities post-stroke. Thus, pharmacologic SR inhibition has potential clinical applications.

AB - Parkinson's disease (PD) is a neurodegenerative disease caused by a gradual loss of midbrain dopaminergic (mDA) neurons in the substantia nigra pars compacta (SNpc) during aging. 1-Methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) is one of the neurotoxins used widely to induce PD-like symptoms in PD animal models, including rodents and non-human primates. It has been reported that deletion of autophagy-related gene 7 (Atg7) in the brain results in a reduction of mDA neurons in adulthood. In this study, we used tyrosine hydroxylase (TH)-Cre mice to generate conditional knockout (CKO) mice with the specific deletion of Atg7 in mDA neurons. Consistent with previous reports, adult Atg7 CKO mice contained fewer TH-positive mDA neurons compared with wild-type (WT) controls. TH expressing neurons containing puncta-like structures with p62 and ubiquitin immunoreactivity were observed in the midbrain of Atg7 CKO mice but were not detected in control mice. However, MPTP-induced loss of mDA neurons was not observed in Atg7 CKO mice. Our results indicate that Atg7-involved autophagy is required not only for the survival of mDA neurons in the mouse brain, but also for MPTP-induced mDA neuron degeneration. PMID- 27693473 TI - I can't reach it! Focus on theta sensorimotor rhythm toward a better understanding of impaired action-perception coupling. AB - It is known that anxiety (ANX) impairs action-perception coupling. This study tests whether this impairment could be associated with an alteration of the sensorimotor function. To this aim, the cortical activities underlying the sensorimotor function were recorded in twelve volunteers in a reach-to-grasp paradigm, in which the level of ANX and the position of a glass were manipulated. The experimental manipulation of the ANX-related somatosensory state was expected to prompt participants to underestimate their reaching-to-grasp capabilities while the sensorimotor-related oscillatory brain activities around the 6-Hz (theta) frequency over motor-related and parietal regions were expected to be modulated. We also investigated the oscillatory brain dynamics around the 11.5-Hz (fast-alpha) frequency as a neural hallmark of ANX manipulation induced by the breath-restriction. Results indeed showed that participants underestimated their reaching-to-grasp maximal performance. Concomittantly, theta-EEG synchronization over the motor cortex contralateral to the dominant hand was higher during glass presentation under breath-restriction condition (+20.1%; p<0.05), and when the glass was perceived as non-reachable (+20.0%; p<0.05). Fast-alpha-EEG desynchronization was reduced under breath-restriction (-37.7%; p<0.05). The results confirm that ANX-related impairment of action-perception coupling co modulates with theta-sensorimotor rhythm. This finding is discussed as an altered "readiness state" in the reaching-related cortical network, while individuals are anxious. PMID- 27693475 TI - Electrophysiological assessment of driving pleasure and difficulty using a task irrelevant probe technique. AB - The amplitude of event-related brain potentials (ERPs) elicited by task irrelevant auditory probes decreases when more attentional resources are allocated to a visual task. This task-irrelevant probe technique is considered to be useful in assessing the degree of interest in a visual task, as well as task difficulty. The present study examined the amplitude of the N1 and P2 components elicited by task-irrelevant auditory probes during a driving task in a simulated environment. The analysis of ERPs showed that the N1 amplitude decreased when participants drove on the road course that had more frequent and sharper curves, whereas the P2 amplitude decreased when the road contained sharper curves, irrespective of curve frequency. Subjective ratings of driving pleasure and difficulty showed the same variation patterns as the N1 and P2 amplitudes, respectively. These results suggest that use of the task-irrelevant probe technique can assess the degree of driving pleasure and difficulty separately.

AB - Orexin neurons are known to augment the sympathetic control of cardiovascular function, however the role of orexin neurons in parasympathetic cardiac regulation remains unclear. To test the hypothesis that orexin neurons contribute to parasympathetic control we selectively expressed channelrhodopsin-2 (ChR2) in orexin neurons in orexin-Cre transgenic rats and examined postsynaptic currents in cardiac vagal neurons (CVNs) in the dorsal motor nucleus of the vagus (DMV). Simultaneous photostimulation and recording in ChR2-expressing orexin neurons in the lateral hypothalamus resulted in reliable action potential firing as well as large whole-cell currents suggesting a strong expression of ChR2 and reliable optogenetic excitation. Photostimulation of ChR2-expressing fibers in the DMV elicited short-latency (ranging from 3.2ms to 8.5ms) postsynaptic currents in 16 out of 44 CVNs tested. These responses were heterogeneous and included excitatory glutamatergic (63%) and inhibitory GABAergic (37%) postsynaptic currents. The results from this study suggest different sub-population of orexin neurons may exert diverse influences on brainstem CVNs and therefore may play distinct functional roles in parasympathetic control of the heart. PMID- 27693477 TI - Cervical disc arthroplasty for symptomatic cervical disc disease: Traditional and Bayesian meta-analysis with trial sequential analysis. AB - OBJECTIVE: Cervical disc arthroplasty (CDA) has been designed as a substitute for anterior cervical discectomy and fusion (ACDF) in the treatment of symptomatic cervical disc disease (CDD). Several researchers have compared CDA with ACDF for the treatment of symptomatic CDD; however, the findings of these studies are inconclusive. Using recently published evidence, this meta-analysis was conducted to further verify the benefits and harms of using CDA for treatment of symptomatic CDD. METHODS: Relevant trials were identified by searching the PubMed, EMBASE, and Cochrane Library databases. Outcomes were reported as odds ratio or standardized mean difference. Both traditional frequentist and Bayesian approaches were used to synthesize evidence within random-effects models. Trial sequential analysis (TSA) was applied to test the robustness of our findings and obtain more conservative estimates. RESULTS: Nineteen trials were included. The findings of this meta-analysis demonstrated better overall, neck disability index (NDI), and neurological success; lower NDI and neck and arm pain scores; higher 36-Item Short Form Health Survey (SF-36) Physical Component Summary (PCS) and Mental Component Summary (MCS) scores; more patient satisfaction; greater range of motion at the operative level; and fewer secondary surgical procedures (all P < 0.05) in the CDA group compared with the ACDF group. CDA was not significantly different from ACDF in the rate of adverse events (P > 0.05). TSA of overall success suggested that the cumulative z-curve crossed both the conventional boundary and the trial sequential monitoring boundary for benefit, indicating sufficient and conclusive evidence had been ascertained. CONCLUSIONS: For treating symptomatic CDD, CDA was superior to ACDF in terms of overall, NDI, and neurological success; NDI and neck and arm pain scores; SF-36 PCS and MCS scores; patient satisfaction; ROM at the operative level; and secondary surgical procedures rate. Additionally, there was no significant difference between CDA and ACDF in the rate of adverse events. However, as the CDA procedure is a relatively newer operative technique, long-term results and evaluation are necessary before CDA is routinely used in clinical practice. PMID- 27693479 TI - T-shaped Shunt With Intracavernosal Tunneling for a Pediatric Case of Refractory Ischemic Priapism. AB - We present the first reported case of refractory pediatric priapism treated by intracavernosal tunneling T shunt. A 12-year-old male, with sickle cell disease, presented with 72 hours of painful erection. The patient failed conservative measures including aspiration, injection of phenylephrine, as well as distal shunt procedure. A T-T shunt was performed, as previously described in the adult literature. There was immediate resolution of the erection with no complications. At 1-year follow-up, he reports no subsequent episodes of priapism and normal erections. T shunt with tunneling can be performed in select cases of severe pediatric refractory ischemic priapism. PMID- 27693478 TI - Dismembered Pyeloplasty in Infants 6 Months Old or Younger With and Without External Trans-anastomotic Nephrostent: A Prospective Randomized Study. AB - OBJECTIVE: To compare the outcome of dismembered pyeloplasty in infants with and without external nephro-ureteric stent (ENUS) for treatment of congenital ureteropelvic junction obstruction. METHODS: This is a parallel, randomized comparative study between October 2013 and September 2014. Thirty infants <=6 months old with ureteropelvic junction obstruction indicated for dismembered pyeloplasty were randomly assigned (block randomization, closed envelope method) into two groups: group A (stentless) and group B (ENUS). Infants with solitary kidney, gross pyuria, huge pelvis, vesicoureteric reflux, or other renal anomalies were excluded. Operative data, complications, and ultrasonographic and nuclear scintigraphy criteria were compared after at least 18 months of follow-up using Student t, Mann-Whitney U, Kruskal-Wallis, chi-square, and Fisher exact tests when appropriate. Occurrence of urinary leakage was the primary outcome. RESULTS: Included patients completed the study with intention-to-treat analysis. All children had normal renal function. The mean operative time was 85.3 +/- 6.3 (60-90) minutes in group A and 92.6 +/- 15.3 (70-120) minutes in group B (P = .2). Although there was a significant postoperative improvement in each group in split renal function and anterior-posterior renal pelvis diameter, there was no significant difference between both groups. The mean hospital stay for group A and group B was 5.9 +/- 2 (4-10) days versus 3.5 +/- 0.8 (2-5) days, respectively (P < .001). Postoperative urinary leakage was reported only in group A (40%). All complications were managed by double J insertion. Auxiliary interventions were higher in group A. The overall success rate was 93.4%. Redo pyeloplasty was performed in one case in each group. CONCLUSION: ENUS significantly reduces hospital stay and complications. It saves the infant hazards of auxiliary interventions under general anesthesia for management of leakage or double J removal if placed at time of pyeloplasty. PMID- 27693480 TI - Calcifying Fibrous Tumor of the Tunica Vaginalis Testis: A Report of 2 Cases. AB - OBJECTIVE: To improve the clinical diagnosis and treatment of calcifying fibrous tumor (CFT) of the tunica vaginalis testis, we discussed clinical manifestations and pathologic features of CFT. MATERIALS AND METHODS: A retrospective analysis of 2 cases of CFT that occurred in our hospital was performed, and we also reviewed the literature and research reports. RESULTS: Both patients underwent local excision with testis preservation surgery, and pathology examination confirmed the presence of multiple CFTs of the tunica vaginalis testis. CONCLUSION: CFTs are rare, benign multiple lesions, and the recognition of which needs to be improved to avoid overtreatment. We are the first to describe 2 cases of CFT combined with hepatitis B, but additional studies are needed to confirm the relationship between these conditions.

AB - Antibody deficiencies can be caused by a variety of defects that interfere with B cell development, maturation, and/or function. Using whole-exome sequencing we found a PIK3R1 mutation in a patient with hypogammaglobulinemia and a narrow clinical phenotype of respiratory infections. Early diagnosis is crucial; careful analysis of B and T-cells followed by genetic analyses may help to distinguish activated PI3K-delta syndrome (APDS) from other, less severe, predominantly antibody deficiencies. PMID- 27693482 TI - Experimental evaluation of two different types of reactors for CO2 removal from gaseous stream by bottom ash accelerated carbonation. AB - Low methane content landfill gas may be enriched by removing carbon dioxide. An innovative process, based on carbon dioxide capture and storage by means of accelerated carbonation of bottom ash is proposed and studied for the above purpose. Within this research framework we devoted a preliminary research activity to investigate the possibility of improving the way the contact between bottom ash and landfill gas takes place: this is the scope of the work reported in this paper. Two different types of reactors - fixed bed and rotating drum - were designed and constructed for this purpose. The process was investigated at laboratory scale. As the aim of this phase was the comparison of the performances of the two different reactors, we used a pure stream of CO2 to preliminarily evaluate the reactor behaviors in the most favorable condition for the process (i.e. maximum CO2 partial pressure at ambient condition). With respect to the simple fixed bed reactor concept, some modifications were proposed, consisting of separating the ash bed in three layers. With the three layer configuration we would like to reduce the possibility for the gas to follow preferential paths through the ash bed. However, the results showed that the process performances are not significantly influenced by the multiple layer arrangement. As an alternative to the fixed bed reactor, the rotating drum concept was selected in order to provide continuous mixing of the solids. Two operating parameters were considered and varied during the tests: the filling ratio and the rotating speed. Better performances were observed for lower filling ratio while the rotating speed showed minor importance. Finally the performances of the two reactors were compared. The rotating drum reactor is able to provide improved carbon dioxide removal with respect to the fixed bed one, especially when the rotating reactor is operated at low filling ratio values and slow rotating speed values. Comparing the carbon dioxide specific removal obtained by using the rotating reactor (35 37g/kgBA), in the best operating conditions, with that measured for the fixed bed reactor (21-23g/kgBA), an increase of about 61-66% is observed. PMID- 27693483 TI - Adverse effect of valproic acid on an in vitro gastrulation model entails activation of retinoic acid signaling. AB - Valproic acid (VPA), an antiepileptic drug, is a teratogen that causes neural tube and axial skeletal defects, although the mechanisms are not fully understood. We previously established a gastrulation model using mouse P19C5 stem cell embryoid bodies (EBs), which exhibits axial patterning and elongation morphogenesis in vitro. Here, we investigated the effects of VPA on the EB axial morphogenesis to gain insights into its teratogenic mechanisms. Axial elongation and patterning of EBs were inhibited by VPA at therapeutic concentrations. VPA elevated expression levels of various developmental regulators, including Cdx1 and Hoxa1, known transcriptional targets of retinoic acid (RA) signaling. Co treatment of EBs with VPA and BMS493, an RA receptor antagonist, partially rescued axial elongation as well as gene expression profiles. These results suggest that VPA requires active RA signaling to interfere with EB morphogenesis. PMID- 27693484 TI - Molecular analysis of Ixodes rugicollis, Candidatus Neoehrlichia sp. (FU98) and a novel Babesia genotype from a European badger (Meles meles). AB - The European badger (Meles meles) is a widespread mammal in most countries of the European continent, with increasingly recognized veterinary/medical importance owing to its preferred habitats (including pastures and urban environments), broad spectrum of food items, and role as a game hunting target. However, ticks and tick-borne pathogens associated with badgers are only partly known, and most of them have not yet been analysed with molecular biological methods The aim of this study was to perform molecular taxonomic analysis of ticks collected from a road-killed European badger, as well as to molecularly investigate its ticks and blood sample for the presence of Anaplasmataceae and piroplasms. Ticks from the badger were morphologically identified as females of Ixodes rugicollis. Based on its cytochrome oxidase subunit I (COI) and 16S rRNA sequences, I. rugicollis phylogenetically clustered together with I. lividus and I. arboricola, i.e. other members of the subgenus Pholeoixodes. The blood sample of the badger contained the DNA of Candidatus Neoehrlichia sp. (FU98) recently identified in red fox in Austria and the Czech Republic. This genotype is most closely related to Ca. N. lotoris (from raccoons in North America), and has lower sequence identity with the I. ricinus-transmitted zoonotic agent, Ca. N. mikurensis found in Eurasia. In the blood of the badger and in one female I. rugicollis, the DNA of a new Babesia genotype was also present, which differed from a piroplasm detected in M. meles in Spain, and clustered phylogenetically in the B. microti clade. Phylogenetic analysis of I. rugicollis (based on two genetic markers) confirms its status in subgenus Pholeoixodes. Ca. Neoehrlichia sp. (FU98) was identified for the first time in M. meles and in Hungary. In addition, a molecularly previously not yet characterized Babesia genotype occurs in badgers in Central Europe.

PMID- 27693486 TI - Extracellular matrix dynamics and functions in the social amoeba Dictyostelium: A critical review. AB - BACKGROUND: The extracellular matrix (ECM) is a dynamic complex of glycoproteins, proteoglycans, carbohydrates, and collagen that serves as an interface between mammalian cells and their extracellular environment. Essential for normal cellular homeostasis, physiology, and events that occur during development, it is also a key functionary in a number of human diseases including cancer. The social amoeba Dictyostelium discoideum secretes an ECM during multicellular development that regulates multicellularity, cell motility, cell differentiation, and morphogenesis, and provides structural support and protective layers to the resulting differentiated cell types. Proteolytic processing within the Dictyostelium ECM leads to specific bioactive factors that regulate cell motility and differentiation. SCOPE OF REVIEW: Here we review the structure and functions of the Dictyostelium ECM and its role in regulating multicellular development. The questions and challenges that remain and how they can be answered are also discussed. MAJOR CONCLUSIONS: The Dictyostelium ECM shares many of the features of mammalian and plant ECM, and thus presents an excellent system for studying the structure and function of the ECM. GENERAL SIGNIFICANCE: As a genetically tractable model organism, Dictyostelium offers the potential to further elucidate ECM functions, and to possibly reveal previously unknown roles for the ECM. PMID- 27693487 TI - Plasma kisspeptin and ghrelin levels are independently correlated with physical activity in patients with anorexia nervosa. AB - While physical hyperactivity represents a frequent symptom of anorexia nervosa and may have a deleterious impact on the course of the disease, the underlying mechanisms are poorly understood. Since several food intake-regulatory hormones affect physical activity, the aim of the study was to investigate the association of physical activity with novel candidate hormones (kisspeptin, ghrelin, oxyntomodulin, orexin-A, FGF-21, R-spondin-1) possibly involved in patients with anorexia nervosa. Associations with psychometric parameters and body composition were also assessed. We included 38 female anorexia nervosa inpatients (body mass index, BMI, mean +/- SD: 14.8 +/- 1.7 kg/m2). Physical activity was evaluated using portable armband devices, body composition by bioelectrical impedance analysis. Blood withdrawal (hormones measured by ELISA) and psychometric assessment of depressiveness (PHQ-9), anxiety (GAD-7), perceived stress (PSQ-20) and disordered eating (EDI-2) were performed at the same time. Patients displayed a broad spectrum of physical activity (2479-26,047 steps/day) which showed a negative correlation with kisspeptin (r = -0.41, p = 0.01) and a positive association with ghrelin (r = 0.42, p = 0.01). The negative correlation with oxyntomodulin (r = -0.37, p = 0.03) was lost after consideration of potential confounders by regression analysis. No correlations were observed between physical activity and orexin-A, FGF-21 and R-spondin-1 (p > 0.05). Kisspeptin was positively correlated with BMI and body fat mass and negatively associated with the interpersonal distrust subscale of the EDI-2 (p < 0.01). Depressiveness, anxiety, and perceived stress did not correlate with kisspeptin or any other of the investigated hormones (p > 0.05). In conclusion, kisspeptin is inversely and ghrelin positively associated with physical activity as measured by daily step counts in anorexia nervosa patients suggesting an implication of these peptide hormones in the regulation of physical activity in anorexia nervosa. PMID- 27693488 TI - Do disinhibited eaters pay increased attention to food cues? AB - The Three Factors Eating Questionnaire's measure of disinhibited eating is a robust predictor of long-term weight gain. This experiment explored if disinhibited eaters display attentional bias to food cues. Participants (N = 45) completed a visual dot probe task which measured responses to food (energy dense and low energy foods) and neutral cues. Picture pairs were displayed either for a 100 ms or 2000 ms duration. All participants displayed attentional bias for energy dense food items. Indices of attentional bias were largest in disinhibited eaters. Attentional bias in disinhibited eaters appeared to be underpinned by facilitated attention. PMID- 27693489 TI - Food skills confidence and household gatekeepers' dietary practices. AB - INTRODUCTION: Household food gatekeepers have the potential to influence the food attitudes and behaviours of family members, as they are mainly responsible for food-related tasks in the home. The aim of this study was to determine the role of gatekeepers' confidence in food-related skills and nutrition knowledge on food practices in the home. METHODS: An online survey was completed by 1059 Australian dietary gatekeepers selected from the Global Market Insite (GMI) research database. Participants responded to questions about food acquisition and preparation behaviours, the home eating environment, perceptions and attitudes towards food, and demographics. Two-step cluster analysis was used to identify groups based on confidence regarding food skills and nutrition knowledge. Chi square tests and one-way ANOVAs were used to compare the groups on the dependent variables. RESULTS: Three groups were identified: low confidence, moderate confidence and high confidence. Gatekeepers in the highest confidence group were significantly more likely to report lower body mass index (BMI), and indicate higher importance of fresh food products, vegetable prominence in meals, product information use, meal planning, perceived behavioural control and overall diet satisfaction. Gatekeepers in the lowest confidence group were significantly more likely to indicate more perceived barriers to healthy eating, report more time constraints and more impulse purchasing practices, and higher convenience ingredient use. Other smaller associations were also found. CONCLUSION: Household food gatekeepers with high food skills confidence were more likely to engage in several healthy food practices, while those with low food skills confidence were more likely to engage in unhealthy food practices. Food education strategies aimed at building food-skills and nutrition knowledge will enable current and future gatekeepers to make healthier food decisions for themselves and for their families. PMID- 27693490 TI - High-level expression of l-glutamate oxidase in Pichia pastoris using multi-copy expression strains and high cell density cultivation. AB - l-glutamate oxidase (GLOD), encoded by the gox gene, catalyses the transformation of l-glutamic acid into alpha-ketoglutaric acid (alpha-KG). In the present study, Pichia pastoris was used for heterologous production of GLOD following optimization of the gox coding sequence for expression in the yeast host. A series of constructs based on the pHBM905BDM plasmid were engineered and transformed into P. pastoris to increase the gox copy number. The results indicated that GLOD protein levels and enzyme activity increased with increasing gox copy number. Strain PGLOD4, which contained four copies of the target gene, was chosen for subsequent fermentation experiments, and a fermentation strategy involving two exponential feeding phases was developed. During the preinduction phase, glycerol was fed exponentially at MUG = 0.15/h. When the cell density reached 300 g/l, methanol was fed exponentially at MUM = 0.03/h to induce GLOD production. After 84 h of cultivation, the final cell density and total enzyme activity reached 420 g/L and 247.8 U/mL, respectively. The recombinant enzyme displayed an optimum temperature of 40 degrees C, which was higher than recombinant enzyme expressed in E. coli. This is important because increasing the temperature could accelerate enzymatic transformation of l-glutamic acid to alpha KG. Experiments also demonstrated superior thermo-stability for the enzyme produced in yeast, which further enhances its potential for industrial applications. PMID- 27693491 TI - Oligo-clonal nanobodies as an innovative targeting agent for cancer therapy: New biology and novel targeting systems. AB - Variable heavy chain of HcAb (VHH), the smallest intact antibody fragment, possesses sub-nanomolar affinity to antigens. In spite of conventional antibodies, these fragments recognize concave and linear epitopes. VHHs are one the best weapon for targeted drug delivery in nanomedicine and biopharmaceutics. HER2 is overexpressed in 20-25% of breast and ovarian cancers. For many reasons, HER2 is a prominent target for drug delivery to breast tumor. In this study, we designed a robust prokaryotic expression system to express functional VHHs against HER2 receptor. This system showed high recombinant yields besides purified VHHs flow cytometry verified great capabilities of these molecules to pinpoint ecto-domain of HER2 receptor in MC4L2 HER2+ while insignificant non specific binding to MC4L2 HER2-confirm nanobodies trivial cross-reaction. In the next step, we evaluated cooperative effect of four distinctive VHHs (oligoclonal VHHs) targeting different epitopes on HER2. As our result proved, using oligoclonal nanobodies as targeting moiety enhance targeting efficacy in comparison with monoclonal VHH. PMID- 27693492 TI - CVD 103-HgR vaccine for travelers. PMID- 27693493 TI - miR-1207-3p regulates the androgen receptor in prostate cancer via FNDC1/fibronectin. AB - Prostate cancer (PCa) is frequently diagnosed in men, and dysregulation of microRNAs is characteristic of many cancers. MicroRNA-1207-3p is encoded at the non-protein coding gene locus PVT1 on the 8q24 human chromosomal region, an established PCa susceptibility locus. However, the role of microRNA-1207-3p in PCa is unclear. We discovered that microRNA-1207-3p is significantly underexpressed in PCa cell lines in comparison to normal prostate epithelial cells. Increased expression of microRNA-1207-3p in PCa cells significantly inhibits proliferation, migration, and induces apoptosis via direct molecular targeting of FNDC1, a protein which contains a conserved protein domain of fibronectin (FN1). FNDC1, FN1, and the androgen receptor (AR) are significantly overexpressed in PCa cell lines and human PCa, and positively correlate with aggressive PCa. Prostate tumor FN1 expression in patients that experienced PCa specific death is significantly higher than in patients that remained alive. Furthermore, FNDC1, FN1 and AR are concomitantly overexpressed in metastatic PCa. Consequently, these studies have revealed a novel microRNA-1207-3p/FNDC1/FN1/AR regulatory pathway in PCa.

AB - Tumor metastasis is the main reason of death for hepatocellular carcinoma (HCC) patients. Cell migration and invasion are two prerequisites for tumor metastasis, in which TRPM7 and MMPs play an important role. In our study, we found that bradykinin (BK) could upregulate the expression of TRPM7 and dynamically regulate the phosphorylation of non-muscle myosin IIA heavy chain (NMHC-IIA) Ser-1943 in HepG2 cells. The influx of Ca2+ via TRPM7 was necessary for elevating the activity of m-calpain and MU-calpain. Additionally, we observed that BK stimulated HepG2 cells to secrete more MMP2 but not MMP9. Src was critical in the process of MMP2 secretion and invadopodia formation. The heat map showed that BDKRB2, TRPM7 and MMP2 had higher overexpression proportions in 25 HCC cell lines. Some clinical specimens of HCC also indicated that BDKRB2 and MMP2 were overexpressed. In conclusion, BK promoted migration and invasion of HCC cells through TRPM7 and MMP2.

AB - Inflammatory response played an important role in the progression of spinal cord injury (SCI). Several miRNAs were associated with the pathology of SCI. However, the molecular mechanism of miRNA involving in inflammatory response in acute SCI (ASCI) was poorly understood. Sprague-Dawley (SD) rats were divided into 2 groups: control group (n=6) and acute SCI (ASCI) group (n=6). The expression of miR-199b and IkappaB kinase beta-nuclear factor-kappa B (IKKbeta-NF-kappaB) signaling pathway were evaluated by quantitative reverse transcription-PCR (qRT PCR) in rats with ASCI and in primary microglia activated by lipopolysaccharide (LPS). We found that downregulation of miR-199b and activation of IKKbeta/NF kappaB were observed in rats after ASCI and in activated microglia. miR-199b negatively regulated IKKbeta by targeting its 3'- untranslated regions (UTR) through using luciferase reporter assay. Overexpression of miR-199b reversed the up-regulation of IKKbeta, p-p65, tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) in LPS-treated BV2 cells assessed by western blotting analysis. In addition, BMS-345541 reversed the up-regulation effects of miR-199b inhibitor on the expression of TNF-alpha and IL-1beta. In the SCI rats, overexpression of miR-199b attenuated ASCI and decreased the expression of IKKbeta-NF-kappaB signaling pathway and TNF-alpha and IL-1beta. These results indicated that miR-199b attenuated ASCI at least partly through IKKbeta-NF-kappaB signaling pathway and affecting the function of microglia. Our findings suggest that miR-199b may be employed as therapeutic for spinal cord injury. PMID- 27693496 TI - Ossification of the posterior ligament is mediated by osterix via inhibition of the beta-catenin signaling pathway. AB - Ossification of the posterior longitudinal ligament (OPLL) involves ectopic calcification of the spinal ligament preferentially at the cervical spine. OPLL is associated with different diseases and occurs by endochondral ossification, which is associated with the activity of different transcription factors. However, the pathogenesis of OPLL remains unclear. Here, we investigated the role of osterix (Osx), a transcription factor that functions downstream of Runx2 and is an important regulator of osteogenesis, in the process of OPLL in a dexamethasone (Dex)-induced model of spinal ligament ossification. Our results showed that Osx is upregulated in patients with OPLL and during the ossification of ligament cells in parallel with the upregulation of osteogenic markers including osteocalcin (OCN), alkaline phosphatase (ALP) and collagen-1 (Col-1). Dex-induced ossification of ligament cells was associated with the downregulation and inactivation of beta-catenin, and these effects were offset by Osx knockdown. Activation of beta-catenin signaling abolished the effect of Dex on ossification and the upregulation of osteogenic markers. Taken together, our results suggest that OPLL is mediated by Osx via a mechanism involving the Wnt/beta-catenin signaling pathway, providing a basis for further research to identify potential targets for the treatment of OPLL.

PMID- 27693498 TI - The pulmonary phagocytosis response to separate and combined impacts of manganese (IV) and chromium (VI) containing particulates. AB - We investigated by the optical microscopy some cytological characteristics of the bronchoalveolar lavage fluid cell population 24h after intratracheal instillation of microscale MnO2 and BaCrO4 particles (separately or together at two different doses) into the lungs of Wistar rats. Besides, the cytotoxicity of both particulates for rat peritoneal macrophages in vitro was assessed by the trypan blue exclusion test and proved significant. They were found to evoke a typical dose-dependent pulmonary phagocytosis response usually observed under inhalation or intratracheal impacts of low-soluble mineral and metal particles. A significant shift in the above mentioned cell population toward the prevalence of neutrophllic leukocytes (NL) over alveolar macrophages (AM) proved once more to be the most characteristic feature of this response. Although the particle load of a unit AM was always higher than that of a unit NL, the collective contribution of the recruited NLs to the total particles internalization by both AMs and NLs together was quite significant. This fact confirms that NL recruitment is an important auxiliary mechanism of the cytotoxic particle elimination from lungs compensating for the macrophage damage caused by them. Well adjusted functioning of this compensatory mechanism was additionally demonstrated by isobolographic analysis based on the Response Surface Methodology. On the other hand, this analysis confirmed that the type of combined toxicity depends on a particular effect this type is assessed for and on the effect's dose-dependent level. PMID- 27693499 TI - Integrating in silico models to enhance predictivity for developmental toxicity. AB - Application of in silico models to predict developmental toxicity has demonstrated limited success particularly when employed as a single source of information. It is acknowledged that modelling the complex outcomes related to this endpoint is a challenge; however, such models have been developed and reported in the literature. The current study explored the possibility of integrating the selected public domain models (CAESAR, SARpy and P&G model) with the selected commercial modelling suites (Multicase, Leadscope and Derek Nexus) to assess if there is an increase in overall predictive performance. The results varied according to the data sets used to assess performance which improved upon model integration relative to individual models. Moreover, because different models are based on different specific developmental toxicity effects, integration of these models increased the applicable chemical and biological spaces. It is suggested that this approach reduces uncertainty associated with in silico predictions by achieving a consensus among a battery of models. The use of tools to assess the applicability domain also improves the interpretation of the predictions. This has been verified in the case of the software VEGA, which makes freely available QSAR models with a measurement of the applicability domain. PMID- 27693500 TI - Tribological rehydration of cartilage and its potential role in preserving joint health. AB - OBJECTIVE: During exercise, cartilage recovers interstitial fluid lost during inactivity, which explains how tissue thickness and joint space are maintained over time. This recovery phenomenon is currently explained by a combination of osmotic swelling during intermittent bath exposure and sub-ambient pressurization during unloading. This paper tests an alternate hypothesis that cartilage can retain and recover interstitial fluid in the absence of bath exposure and unloading when physiological hydrodynamics are present. METHOD: Stationary cartilage-on-flat experiments were conducted to eliminate intermittent bath exposure as a potential contributor to fluid uptake. In situ compression measurements were used to monitor the loss, retention, and recovery of interstitial fluid during testing in saline. Samples were left larger than the contact area to preserve a convergence zone for hydrodynamic pressurization. RESULTS: Interstitial fluid lost during static loading was recovered during sliding in the absence of unloading and contact migration; fluid recovery in a stationary contact cannot be explained by biphasic theory and suggests a fundamentally new contributor to the recovery process. We call the phenomenon 'tribological rehydration' because recovery was induced by sliding rather than by unloading or migration. Sensitivities to sliding speed, surface permeability, and nature of the convergence wedge are consistent with the hypothesis that hydrodynamic effects underlie the tribological rehydration phenomenon. CONCLUSIONS: This study demonstrates that cartilage can retain and recover interstitial fluid without migration or unloading. The results suggest that hydrodynamic effects in the joint are not only important contributors to lubrication, they are likely equally important to the preservation of joint space. PMID- 27693502 TI - Vitamin E protects rat mesenchymal stem cells against hydrogen peroxide-induced oxidative stress in vitro and improves their therapeutic potential in surgically induced rat model of osteoarthritis. AB - OBJECTIVE: Oxidative stress is a major obstacle against cartilage repair in osteoarthritis (OA). Anti-oxidant agents can play a vital role in addressing this issue. We evaluated the effect of Vitamin E preconditioning in improving the potential of mesenchymal stem cells (MSCs) to confer resistance against oxidative stress prevailing during OA. METHODS: Vitamin E pretreated MSCs were exposed to oxidative stress in vitro by hydrogen peroxide (H2O2) and also implanted in surgically-induced rat model of OA. Analysis was done in terms of cell proliferation, apoptosis, cytotoxicity, chondrogenesis and repair of cartilage tissue. RESULTS: Vitamin E pretreatment enabled MSCs to counteract H2O2-induced oxidative stress in vitro. Proliferative markers, proliferating cell nuclear antigen (PCNA) and Ki67 were up-regulated, along with the increase in the viability of MSCs. Expression of transforming growth factor-beta (TGFbeta) was also increased. Reduction of apoptosis, expression of vascular endothelial growth factor (VEGF) and caspase 3 (Casp3) genes, and lactate dehydrogenase (LDH) release were also observed. Transplantation of Vitamin E pretreated MSCs resulted in increased proteoglycan contents of cartilage matrix. Increased expression of chondrogenic markers, Aggrecan (Acan) and collagen type-II alpha (Col2a1) accompanied by decreased expression of collagen type-I alpha (Col1a1) resulted in increased differentiation index that signifies the formation of hyaline cartilage. Further, there was an increased expression of PCNA and TGFbeta genes along with a decreased expression of Casp3 and VEGF genes with increased histological score. CONCLUSION: Taken together results of this study demonstrated that Vitamin E pretreated MSCs have an improved ability to impede the progression of OA and thus increased potential to treat OA. PMID- 27693501 TI - Suppression of Sestrins in aging and osteoarthritic cartilage: dysfunction of an important stress defense mechanism. AB - OBJECTIVES: Aging is an important osteoarthritis (OA) risk factor and compromised stress defense responses may mediate this risk. The Sestrins (Sesn) promote cell survival under stress conditions and regulate AMP-activated protein kinase (AMPK) and mammalian target of rapamycin (mTOR) signaling. This study examined Sesn expression in normal and OA cartilage and functions of Sesn in chondrocytes. METHODS: Sesn expression in human and mouse normal and OA cartilage was analyzed by quantitative polymerase chain reaction (PCR) and immunohistochemistry. Sesn function was investigated by using small interfering RNA (siRNA) mediated Sesn knockdown and overexpression with analysis of cell survival, gene expression, autophagy, and AMPK and mTOR activation. RESULTS: Sesn mRNA levels were significantly reduced in human OA cartilage and immunohistochemistry of human and mouse OA cartilage also showed a corresponding reduction in protein levels. In cultured human chondrocytes Sesn1, 2 and 3 were expressed and increased by tunicamycin, an endoplasmic reticulum (ER) stress response inducer and 2 deoxyglucose (2DG), a metabolic stress inducer. Sesn1 and 2 were increased by tBHP, an oxidative stress inducer. Sesn knockdown by siRNA reduced chondrocyte viability under basal culture conditions and in the presence of 2DG. Sesn overexpression enhanced LC3-II formation and autophagic flux, and this was related to changes in mTOR but not AMPK activation. CONCLUSION: These findings are the first to show that Sesn expression is suppressed in OA affected cartilage. Sesn support chondrocyte survival under stress conditions and promote autophagy activation through modulating mTOR activity. Suppression of Sesn in OA cartilage contributes to deficiency in an important cellular homeostasis mechanism. PMID- 27693503 TI - Anterior knee pain following anterior cruciate ligament reconstruction does not increase the risk of patellofemoral osteoarthritis at 15- and 20-year follow-ups. AB - OBJECTIVE: To prospectively evaluate the relationship between the presence or persistence of anterior knee pain (AKP) during the first 2-years following anterior cruciate ligament reconstruction (ACLR) and patellofemoral osteoarthritis (PFOA) at 15- and 20-years. DESIGN: This study was ancillary to a long-term prospective cohort study of 221 participants following bone-patellar tendon-bone ACLR. AKP was assessed at 1- and 2-years post-ACLR using part of the Cincinnati knee score with an additional pain location question (persistence defined as presence at both follow-ups). Radiographic PFOA (definite patellofemoral osteophyte) and symptomatic PFOA (patellofemoral osteophyte, with knee pain during past 4 weeks) was assessed at 15- and 20-years follow-up. We used generalized linear models with Poisson regression to assess the relationship between AKP and PFOA. RESULTS: Of the 181 participants (82%) who were assessed at 15-years post-ACLR (age 39 +/- 9 years; 42% female), 36 (24%) and 33 (22%) had AKP at 1- and 2-years, respectively, while 14 (8%) reported persistent AKP. Radiographic and symptomatic PFOA was observed at 15-years in 130 (72%) and 70 (39%) participants, respectively, and at 20-years in 115 (80%) and 60 (42%) participants, respectively. Neither the presence nor persistence of AKP at 1- and/or 2-years post-ACLR was associated with significantly higher risk of radiographic or symptomatic PFOA at 15- or 20-years (risk ratios <2.1). CONCLUSIONS: Although AKP and PFOA were prevalent, AKP does not appear to be associated with long-term PFOA following ACLR. PMID- 27693504 TI - Relative left frontal activity in reappraisal and suppression of negative emotion: Evidence from frontal alpha asymmetry (FAA). AB - Previous studies have shown that reappraisal (changing the way that one thinks about emotional events) is an effective strategy for regulating emotion, compared with suppression (reducing emotion-expressive behavior). In the present study, we investigated relative left frontal activity when participants were instructed to use reappraisal and suppression of negative emotion, by measuring frontal alpha asymmetry (FAA). Two electroencephalography (EEG) experiments were conducted; FAA was analyzed while 102 healthy participants (59 men, 43 women) watched negative images after being instructed to perform reappraisal (Experiment 1) and suppression (Experiment 2). Habitual use of reappraisal and suppression was also assessed using the emotion regulation questionnaire (ERQ). The results of Experiment 1 showed that relative left frontal activity was greater when instructed to use reappraisal of negative images than when normally viewing negative images. In contrast, we observed no difference between conditions of instructed suppression and normal viewing in Experiment 2. In addition, in male participants, habitual use of reappraisal was positively correlated with increased relative left frontal activity for instructed reappraisal, while habitual use of suppression did not show a significant correlation with changes in relative left frontal activity for instructed suppression. These results suggest that emotional responses to negative images might be decreased for instructed reappraisal, but not suppression. These findings support previous reports that reappraisal is an effective emotion regulation strategy, compared with suppression. PMID- 27693505 TI - Drug resistance in ALK-positiveNon-small cell lungcancer patients. AB - Patients are diagnosed as anaplastic lymphoma kinase (ALK) positive, i.e. exhibiting the ALK rearrangement, and comprise 3-7% of non-small-cell lung cancer (NSCLC) cases. Three generations of ALK inhibitors have been developed and used in targeted therapy, although there are still improving spaces of drug resistance at the initiation of each treatment. The current review discusses the pathophysiology of ALK-positive NSCLC and the role of three generations of ALK target inhibitors including crizotinib, ceritinib, alectinib and lorlatinib, as well as the mechanisms of the secondary resistance. We mainly focused on the point mutations that are the most important resistance-producing mechanism and most common form caused by each inhibitor. In addition, we examine the three dimensional structure of ALK to understand the functional impact of these mutations and analyse the underlying molecular mechanisms of the resistance to each generation of ALK inhibitor to benefit the selection decision of the most rational therapy and improve therapeutic effects to the disease. PMID- 27693507 TI - Cell-Intrinsic Adaptation Arising from Chronic Ablation of a Key Rho GTPase Regulator. AB - Genome-editing technologies allow systematic inactivation of human genes. Whether knockout phenotypes always reflect gene functions as determined by acute RNAi is an important question. Here we show how the acute knockdown of the Adams-Oliver syndrome (AOS) gene DOCK6, coding for a RAC1/CDC42 guanine nucleotide exchange factor, results in strikingly different phenotypes to those generated by genomic DOCK6 disruption. Cell-intrinsic adaptation compensates for loss of DOCK6 function. Prolonged DOCK6 loss impacts upon the MRTF-A/SRF transcription factor, reducing levels of the ubiquitin-like modifier ISG15. Reduced ISGylation of the IQGAP1 protein increases levels of active CDC42 and RAC1 to compensate for DOCK6 disruption. Similar downregulation of ISG15 in cells from DOCK6 AOS patients indicates that such adaptation can compensate for genetic defects during development. Thus, phenotypes of gene inactivation are critically dependent on the timescale, as acute knockdown reflects a transient state of adjustment to a new equilibrium that is attained following compensation. PMID- 27693506 TI - TRIMs and Galectins Globally Cooperate and TRIM16 and Galectin-3 Co-direct Autophagy in Endomembrane Damage Homeostasis. AB - Selective autophagy performs an array of tasks to maintain intracellular homeostasis, sterility, and organellar and cellular functionality. The fidelity of these processes depends on precise target recognition and limited activation of the autophagy apparatus in a localized fashion. Here we describe cooperation in such processes between the TRIM family and Galectin family of proteins. TRIMs, which are E3 ubiquitin ligases, displayed propensity to associate with Galectins. One specific TRIM, TRIM16, interacted with Galectin-3 in a ULK1-dependent manner. TRIM16, through integration of Galectin- and ubiquitin-based processes, coordinated recognition of membrane damage with mobilization of the core autophagy regulators ATG16L1, ULK1, and Beclin 1 in response to damaged endomembranes. TRIM16 affected mTOR, interacted with TFEB, and influenced TFEB's nuclear translocation. The cooperation between TRIM16 and Galectin-3 in targeting and activation of selective autophagy protects cells from lysosomal damage and Mycobacterium tuberculosis invasion. PMID- 27693508 TI - Systemic Analysis of Atg5-Null Mice Rescued from Neonatal Lethality by Transgenic ATG5 Expression in Neurons. AB - Autophagy is a cytoplasmic degradation system that is important for starvation adaptation and cellular quality control. Previously, we reported that Atg5-null mice are neonatal lethal; however, the exact cause of their death remains unknown. Here, we show that restoration of ATG5 in the brain is sufficient to rescue Atg5-null mice from neonatal lethality. This suggests that neuronal dysfunction, including suckling failure, is the primary cause of the death of Atg5-null neonates, which would further be accelerated by nutrient insufficiency due to a systemic failure in autophagy. The rescued Atg5-null mouse model, as a resource, allows us to investigate the physiological roles of autophagy in the whole body after the neonatal period. These rescued mice demonstrate previously unappreciated abnormalities such as hypogonadism and iron-deficiency anemia. These observations provide new insights into the physiological roles of the autophagy factor ATG5. PMID- 27693509 TI - The CAMSAP3-ACF7 Complex Couples Noncentrosomal Microtubules with Actin Filaments to Coordinate Their Dynamics. AB - For adaptation to complex cellular functions, dynamic cytoskeletal networks are required. There are two major components of the cytoskeleton, microtubules and actin filaments, which form an intricate network maintaining an exquisite cooperation to build the physical basis for their cellular function. However, little is known about the molecular mechanism underlying their synergism. Here, we show that in Caco2 epithelial cells, noncentrosomal microtubules crosstalk with F-actin through their minus ends and contribute to the regulation of focal adhesion size and cell migration. We demonstrate that ACF7, a member of the spectraplakin family of cytoskeletal crosslinking proteins, interacts with Nezha (also called CAMSAP3) at the minus ends of noncentrosomal microtubules and anchors them to actin filaments. Those noncentrosomal microtubules cooperate with actin filaments through retrograde flow to keep their length and orientation perpendicular to the cell edge as well as regulate focal adhesion size and cell migration. PMID- 27693510 TI - Characterization of novel dystonia musculorum mutant mice: Implications for central nervous system abnormality. AB - We identified a novel spontaneous mutant mouse showing motor symptoms that are similar to those of the dystonia musculorum (dt) mouse. The observations suggested that the mutant mice inherited the mild dt phenotype as an autosomal recessive trait. Linkage analysis showed that the causative gene was located near D1Mit373 and D1Mit410 microsatellite markers on chromosome 1, which are close to the dystonin (Dst) gene locus. To investigate whether Dst is the causative gene of the novel mutant phenotype, we crossed the mutant with Dst gene trap (DstGt) mice. Compound heterozygotes showed a typical dt phenotype with sensory degeneration and progressive motor symptoms. DNA sequencing analysis identified a nonsense mutation within the spectrin repeats of the plakin domain. The novel mutant allele was named dt23Rbrc. Motor abnormalities in homozygous dt23Rbrc/dt23Rbrc mice are not as severe as homozygous DstGt/DstGt mice. Histological analyses showed abnormal neurofilament (NF) accumulation in the nervous system of homozygous dt23Rbrc/dt23Rbrc mice, which is characteristic of the dt phenotype. We mapped the distribution of abnormal NF-accumulated neurons in the brain and found that they were located specifically in the brainstem, spinal cord, and in regions such as the vestibular nucleus, reticular nucleus, and red nucleus, which are implicated in posture and motor coordination pathways. The quantification of abnormal NF accumulation in the cytoplasm and spheroids (axons) of neurons showed that abnormal NF immunoreactivity was lower in homozygous dt23Rbrc/dt23Rbrc mice than in homozygous DstGt/DstGt mice. Therefore, we have identified a novel hypomorphic allele of dt, which causes histological abnormalities in the central nervous system that may account for the abnormal motor phenotype. This novel spontaneously occurring mutant may become a good model of hereditary sensory and autonomic neuropathy type 6, which is caused by mutations in the human DST gene. PMID- 27693512 TI - Cutaneous microvascular reactivity and aortic elasticity in coronary artery disease: Comparison of the laser Doppler flowmetry and echocardiography. AB - BACKGROUND AND AIM: Decreased vascular reactivity in atherosclerosis was previously shown. In our study, it was aimed to demonstrate the decreased vascular functions in both microvascular and macrovascular tissues and to estimate any correlation between them. METHODS: Twenty-five control outpatients with no coronary artery disease (CAD) history and 26 outpatients with CAD history were enrolled in the study. Local cutaneous post-occlusive reactive hyperemia (PORH) responses after three minutes of brachial occlusion with a pneumatic cuff were recorded noninvasively by a Perimed Periflux 5010 laser Doppler flow system. Aortic distensibility and stiffness indexes were recorded noninvasively by a two dimensional Doppler echocardiography machine (Vivid S6 GE Medical System, Horten, Norway). RESULTS: Except for the medication history of subjects, there were no significant demographic differences between the CAD and control groups. Peak flow (PF), resting flow (RF) and biological zero(BZ) laser Doppler measurements were not decreased, but PF-RF/RF (%), PF-BZ/BF (%), hyperemia repayment and PORH indexes were significantly decreased in the CAD group (P=0.005, P=0.024, P=0.017, P=0.006, respectively) with laser Doppler measurements. Aortic strain (%) and aortic distensibility (cm3/dyn-1) measurements were significantly decreased in the CAD group (P=0.005, P=0.013). However, there was no correlation between microvascular indexes (hyperemia repayment index, PORH index) and macrovascular indexes (aortic strain and aortic distensibility). DISCUSSION: Different corrupted vascular tonus regulator systems in arteries of varying diameter, different major reactive responses to the stimuli or, finally, the lack of a number of subjects to obtain a significant level may be responsible for the irrelevant correlation analysis. CONCLUSION: The differences in arterial beds (both aorta and microcirculation) may be examined to assess the cardiovascular risk in patients with history of CAD. PMID- 27693513 TI - Diagnostic utility of fractional exhaled nitric oxide in prolonged and chronic cough according to atopic status. AB - BACKGROUND: Cough-variant asthma (CVA) and cough-predominant asthma (CPA) are the major causes of persistent cough in Japan. The utility of fractional exhaled nitric oxide (FeNO) measurement in the differential diagnosis of persistent cough has been reported, but the influence of atopic status, which is associated with higher FeNO levels, on the diagnostic utility of FeNO has been unknown. METHODS: We retrospectively analyzed 105 non-smoking patients with prolonged and chronic cough that were not treated with corticosteroids and anti-leukotrienes. RESULTS: CPA was diagnosed in 37 patients, CVA in 40, and non-asthmatic cough (NAC) in 28. FeNO levels were significantly higher in the CPA [35.8 (7.0-317.9) ppb] and CVA [24.9 (3.1-156.0) ppb] groups than in the NAC group [18.2 (6.9-49.0) ppb] (p < 0.01 by Kruskal-Wallis test). The optimal cut-off for distinguishing asthmatic cough (AC; CPA and CVA) from NAC was 29.2 ppb [area under the curve (AUC) 0.74, p < 0.01]. Ninety-one percent of subjects with FeNO levels >=29.2 ppb had AC. Meanwhile, 40% of AC patients had FeNO levels <29.2 ppb. Stratified cut-off levels were 31.1 ppb (AUC 0.83) in atopic subjects vs. 19.9 ppb (AUC 0.65) in non atopic subjects (p = 0.03 for AUC). CONCLUSIONS: Although high FeNO levels suggested the existence of AC, lower FeNO levels had limited diagnostic significance. Atopic status affects the utility of FeNO levels in the differential diagnosis of prolonged and chronic cough. PMID- 27693511 TI - Infection of Hepatocytes With HCV Increases Cell Surface Levels of Heparan Sulfate Proteoglycans, Uptake of Cholesterol and Lipoprotein, and Virus Entry by Up-regulating SMAD6 and SMAD7. AB - BACKGROUND & AIMS: The signaling molecule and transcriptional regulator SMAD6, which inhibits the transforming growth factor beta signaling pathway, is required for infection of hepatocytes by hepatitis C virus (HCV). We investigated the mechanisms by which SMAD6 and another inhibitory SMAD (SMAD7) promote HCV infection in human hepatoma cells and hepatocytes. METHODS: We infected Huh7 and Huh7.5.1 cells and primary human hepatocytes with Japanese fulminant hepatitis-1 (JFH1) HCV cell culture system (HCVcc). We then measured HCV binding, intracellular levels of HCV RNA, and expression of target genes. We examined HCV entry in HepG2/microRNA (miR) 122/CD81 cells, which support entry and replication of HCV, were transfected these cells with small interfering RNAs targeting inhibitory SMADs to analyze gene expression profiles. Uptake of labeled low density lipoprotein (LDL) and cholesterol was measured. Cell surface proteins were quantified by flow cytometry. We obtained liver biopsy samples from 69 patients with chronic HCV infection and 19 uninfected individuals (controls) and measured levels of syndecan 1 (SDC1), SMAD7, and SMAD6 messenger RNAs (mRNAs). RESULTS: Small interfering RNA knockdown of SMAD6 blocked the binding and infection of hepatoma cell lines and primary human hepatocytes by HCV, whereas SMAD6 overexpression increased HCV infection. We found levels of mRNAs encoding heparan sulfate proteoglycans (HSPGs), particularly SDC1 mRNA, and cell surface levels of heparan sulfate to be reduced in cells after SMAD6 knockdown. SMAD6 knockdown also reduced transcription of genes encoding lipoprotein and cholesterol uptake receptors, including the LDL receptor (LDLR), the very LDLR, and the scavenger receptor class B member 1 in hepatocytes; knockdown of SMAD6 also inhibited cell uptake of cholesterol and lipoprotein. Overexpression of SMAD6 increased the expression of these genes. Similar effects were observed with knockdown and overexpression of SMAD7. In addition, HCV infection of cells increased the expression of SMAD6, which required the activity of nuclear factor kappaB, but not transforming growth factor beta. Liver tissues from patients with chronic HCV infection had significantly higher levels of SMAD6, SMAD7, and HSPG mRNAs than controls. CONCLUSIONS: In studies of hepatoma cell lines and primary human hepatocytes, we found that infection with HCV leads to activation of nuclear factor-kappaB, resulting in increased expression of SMAD6 and SMAD7. Up regulation of SMAD6 and SMAD7 induces the expression of HSPGs, such as SDC1, as well as LDLR, very LDLR, and the scavenger receptor class B member 1, which promote HCV entry and propagation, as well as cellular uptake of cholesterol and lipoprotein. PMID- 27693514 TI - Hepatectomy for patients with alveolar echinococcosis: Long-term follow-up observations of 144 cases. AB - BACKGROUND: Western China is a region in which alveolar echinococcosis (AE) is endemic. Few studies and comparisons have evaluated the outcomes of AE patients after hepatectomy, and no strategy has been defined for the treatment of AE patients with unresectable tumors. This study sought to assess the outcomes of AE patients after hepatectomy at a tertiary referral center. PATIENTS AND METHODS: We retrospectively analyzed data from 144 patients with hepatic AE who were treated via hepatectomy at our center between January 2004 and December 2015. Patients' overall survival (OS), progression-free survival (PFS), and risk factors were analyzed, and Kaplan-Meier survival curves were constructed. Patient age, year of initial treatment, PNM stage, and risk factors were entered as co variates in a Cox regression modle that was used for analysis. RESULTS: Hepatectomy was performed in 144 patients diagnosed with hepatic AE (84 complete resections and 60 reduction surgeries). In the complete resection group, the 5- and 10-year OS rates were both 97.6%, and the 5- and 10-year PFS rates were both 97.9%. In the reduction surgery group, the 5-, and 10-year OS rates were 89.7% and 73.4%, respectively, and the 5-, and 10-year PFS rates were 78.1% and 69.5%, respectively. Patients in the complete group had better OS prognoses and PFS than patients in the reduction surgery group (P = 0.018 and P = 0.001). Multivariate analysis indicated that curability and portal vein invasion are independent factors associated with PFS (P = 0.028 and P = 0.006). CONCLUSIONS: The most effective therapy for AE is complete resection. Reduction surgery does not appear to offer obvious advantages over benzimidazole therapy alone in the treatment of AE. Curability and portal vein invasion are independent prognostic factors for PFS in a multivariate analysis. PMID- 27693515 TI - How cellular membrane properties are affected by the actin cytoskeleton. AB - Lipid membranes define the boundaries of living cells and intracellular compartments. The dynamic remodelling of these membranes by the cytoskeleton, a very dynamic structure made of active biopolymers, is crucial in many biological processes such as motility or division. In this review, we present some aspects of cellular membranes and how they are affected by the presence of the actin cytoskeleton. We show that, in parallel with the direct study of membranes and cytoskeleton in vivo, biomimetic in vitro systems allow reconstitution of biological processes in a controlled environment. In particular, we show that liposomes, or giant unilamellar vesicles, encapsulating a reconstituted actin network polymerizing at their membrane are suitable models of living cells and can be used to decipher the relative contributions of membrane and actin on the mechanical properties of the cellular interface.

AB - In arthropods, the large majority of studies on olfaction have been focused on insects, where most of the proteins involved have been identified. In particular, chemosensing in insects relies on two families of membrane receptors, olfactory/gustatory receptors (ORs/GRs) and ionotropic receptors (IRs), and two classes of soluble proteins, odorant-binding proteins (OBPs) and chemosensory proteins (CSPs). In other arthropods, such as ticks and mites, only IRs have been identified, while genes encoding for OBPs and CSPs are absent. A third class of soluble proteins, called Niemann-Pick C2 (NPC2) has been suggested as potential carrier for semiochemicals both in insects and other arthropods. Here we report the results of a proteomic analysis on olfactory organs (Haller's organ and palps) and control tissues of the tick Ixodes ricinus, and of immunostaining experiments targeting NPC2s. Adopting different extraction and proteomic approaches, we identified a large number of proteins, and highlighted those differentially expressed. None of the 13 NPC2s known for this species was found. On the other hand, using immunocytochemistry, we detected reaction against one NPC2 in the Haller's organ and palp sensilla. We hypothesized that the low concentration of such proteins in the tick's tissues could possibly explain the discrepant results. In ligand-binding assays the corresponding recombinant NPC2 showed good affinity to the fluorescent probe N-phenylnaphthylamine and to few organic compounds, supporting a putative role of NPC2s as odorant carriers.

AB - Submicron chitosan/tripolyphosphate (TPP) particles are widely investigated as nanocarriers for drugs, genes and vaccines. One of the key particle properties that requires control is their size distribution, which depends on the extent of chitosan/TPP primary nanoparticle aggregation into higher-order submicron colloids. To provide a better understanding of this higher-order aggregation process, this study analyzes the factors that control chitosan/TPP particle aggregation kinetics in the presence of free TPP (such as present during particle formation). The aggregation rates exhibit a sharp power-law decrease with the monovalent salt concentration and a power-law increase with the free TPP concentration. Moreover, the aggregation rates increase with the pH and with the chitosan degree of deacetylation (DD). These variations in aggregation rates reflect the effects of monovalent salt, TPP concentration, pH and chitosan DD on particle bridging by the surface-bound TPP. Furthermore, these aggregation rates are much faster than those predicted based on Derjaguin and Landau, Verwey and Overbeek (DLVO) interaction potentials, which might reflect nonuniformities in particle shape and charge, and/or complications caused by particle softness. Finally, implications of the above aggregation kinetics on the uniformity of chitosan/TPP micro- and nanogel size are analyzed, where we: (1) show how particle polydispersity can be diminished by lowering the chitosan DD; and (2) explain the opposing results on how chitosan/TPP particle polydispersity is affected by monovalent salt.

AB - Gestational carbenoxolone exposure inhibits placental 11beta-hydroxysteroid dehydrogenase (11beta-HSD), the physiological barrier for glucocorticoids, which increases fetal exposure to glucocorticoids and induces intrauterine growth restriction (IUGR). We hypothesized that carbenoxolone exposure influences the expression of placental estrogen receptors-alpha and beta (ERalpha & ERbeta) and p53 leading to inhibited fetal and placental growth. Pregnant Sprague-Dawley rats were injected twice daily with either carbenoxolone (10mg/kg; s.c.) or vehicle (control group) from gestational days (dg) 12 onwards. Maternal blood and placentas were collected on 16 dg, 19 dg and 21 dg. The expression of ERalpha, ERbeta and p53 were studied in placental basal and labyrinth zones by RT-PCR, Western blotting and immunohistochemistry. Carbenoxolone did not affect placental and fetal body weights, but ELISA showed decreased estradiol levels on 19 dg and 21 dg, and increased maternal luteinizing hormone levels on all dg. The follicle stimulating hormone levels decreased on 16 dg and 19 dg, and increased on 21 dg. Carbenoxolone decreased ERalpha mRNA levels on 16 dg in both zones and its protein level on 19 dg in the labyrinth zone. However, carbenoxolone increased ERbeta mRNA levels on 19 dg and 21 dg and protein levels on 16 dg and 19 dg in the labyrinth zone. The p53 mRNA levels increased on all dg, but its protein levels increased on 21 dg in both zones. In conclusion, carbenoxolone exposure changes placental p53, ERalpha, ERbeta expression in favor of cell death but these changes do not induce IUGR in rats. PMID- 27693519 TI - Conductive-probe measurements with nanodots of free-base and metallated porphyrins. AB - The conductive properties of nanodots of model porphyrins were investigated using conductive-probe atomic force microscopy (CP-AFM). Porphyrins provide excellent models for preparing surface structures that can potentially be used as building blocks for devices. The conjugated, planar structure of porphyrins offers opportunities for tailoring the electronic properties. Two model porphyrins were selected for studies, 5,10,15,20-tetraphenyl-21H,23H-porphine cobalt(II) (TPC) and its metal-free analog 5,10,15,20-tetraphenyl-21H,23H-porphine (TPP). Nanodots of TPP and TPC were prepared within a dodecanethiol resist on gold using particle lithography. The nanopatterned surfaces exhibit millions of reproducible test structures of porphyrin nanodots. The porphyrin nanodots have slight differences in dimensions at the nanoscale, to enable size-dependent measurements of conductive properties. The size of the nanodots corresponds to ~5-7 layers of porphyrin. The conductivity along the vertical direction of the nanodots was measured by applying a bias voltage between the gold surface and a metal-coated AFM cantilever. The TPP nanodots exhibited semi-conductive profiles while the TPC nanodots exhibited profiles that are typical of a conductive film or molecular wire. The engineered nanostructures of porphyrins provide an effective platform for investigation and measurement of conductive properties.

AB - The present work reports a surfactant-free, economically feasible chemical route to synthesize bimetallic CuPd alloy nanoparticles under hydrothermal condition. The structural and morphological characterizations of the nanoparticles are carried out by XRD, SEM/EDX, TEM, XPS and BET surface area analyses. The synthetic strategy comprises of 9:1 molar composition of Cu2+ and Pd2+ salt in the aqueous solution. The size of the nanoparticles isca. 3-4nmwith very notable specific surface area of 298m2g-1. The synthesized nanoparticles exhibit excellent catalytic performance towards the aqueous phase reduction of 4 nitrophenol and 4-nitroaniline in the presence of NaBH4 as a reducing agent. Furthermore the CuPd alloy nanoparticles also demonstrate remarkable activity towards reductive conversion of toxic Cr(VI) to less toxic Cr(III) at room temperature. Bimetallic CuPd alloy nanoparticles are catalytically more active and exhibit good recyclability in comparison to the monometallic Cu and Pd due to synergistic effect. PMID- 27693521 TI - Association Between Consumption of Red and Processed Meat and Pancreatic Cancer Risk: A Systematic Review and Meta-analysis. AB - BACKGROUND & AIMS: The relationship between consumption of red and processed meat and pancreatic cancer risk is inconclusive. We conducted a systematic review and meta-analysis to analyze this relationship. METHODS: We performed a systematic search of PubMed, EMBASE, and the Web of Science to identify studies that examined associations between consumption of different kinds of meat with pancreatic cancer and were published through February 2016. By using data from these articles, we associated level of consumption with cancer risk and performed subgroup, meta-regression, and publication bias analyses. RESULTS: We collected and analyzed data from a total of 28 studies that involved 3,143,777 participants (11,325 consumers of red meat) and 2,904,866 participants (9955 consumers of processed meat). We observed statistically significant differences between consumers and non-consumers of these meats in case-control studies (red meat, P = .02; processed meat, P < .01) but not in cohort studies (red meat, P = .09; processed meat, P = .18). In cohort studies, a 100 g/day increase in red meat consumption was associated with significant increase in risk of pancreatic cancer (P = .01); a 50 g/day increase in processed meat consumption was not associated with significant increase in risk of pancreatic cancer (P = .90). In cohort studies, we observed associations in consumption of red meat by men and pancreatic cancer (P < .01) and consumption of processed meat by men and pancreatic cancer (P < .01) but no associations for women (red meat, P = .61; processed meat, P = .88). CONCLUSIONS: In a systematic review and meta-analysis, we found case-control but not cohort studies to associate consumption of red and processed meat with risk of pancreatic cancer. However, in cohort studies, consumption of red and processed meat appeared to increase risk of pancreatic cancer in men but not in women.

AB - An outbreak of dengue fever in Guangdong province in 2014 was the most serious outbreak ever recorded in China. Given the known positive correlation between the abundance of mosquitoes and the number of dengue fever cases, a stage structured mosquito model was developed to investigate the cause of the large abundance of mosquitoes in 2014 and its implications for outbreaks of the disease. Data on the Breteau index (number of containers positive for larvae per 100 premises investigated), temperature and precipitation were used for model fitting. The egg laying rate, the development rate and the mortality rates of immatures and adults were obtained from the estimated parameters. Moreover, effects of daily fluctuations of temperature on these parameters were obtained and the effects of temperature and precipitation were analyzed by simulations. Our results indicated that the abundance of mosquitoes depended not only on the total annual precipitation but also on the distribution of the precipitation. The daily mean temperature had a nonlinear relationship with the abundance of mosquitoes, and large diurnal temperature differences can reduce the abundance of mosquitoes. In addition, effects of increasing precipitation and temperature were interdependent. Our findings suggest that the large abundance of mosquitoes in 2014 was mainly caused by the distribution of the precipitation. In the perspective of mosquito control, our results reveal that it is better to clear water early and spray insecticide between April and August in case of limited resources. PMID- 27693526 TI - A phylogenetic test of sympatric speciation in the Hydrobatinae (Aves: Procellariiformes). AB - Phylogenetic relationships among species can provide insight into how new species arise. For example, careful consideration of both the phylogenetic and geographic distributions of species in a group can reveal the geographic models of speciation within the group. One such model, sympatric speciation, may be more common than previously thought. The Hydrobatinae (Aves: Procellariformes) is a diverse subfamily of Northern Hemisphere storm-petrels for which the taxonomy is unclear. Previous studies showed that Hydrobates (formally Oceanodroma) castro breeding in the Azores during the cool season is sister species to H. monteiroi, a hot season breeder at the same locations, which suggests sympatric speciation by allochrony. To test whether other species within the subfamily arose via sympatric speciation by allochrony, we sequenced the cytochrome b gene and five nuclear introns to estimate a phylogenetic tree using multispecies coalescent methods, and to test whether species breeding in the same geographic area are monophyletic. We found that speciation within the Hydrobatinae appears to have followed several geographic modes of divergence. Sympatric seasonal species in Japan likely did not arise through sympatric speciation, but allochrony may have played a role in the divergence of H. matsudairae, a cool season breeder, and H. monorhis, a hot season breeder. No other potential cases of sympatric speciation were discovered within the subfamily. Despite breeding in the same geographic area, hydrobatine storm-petrels breeding in Baja California (H. microsoma and H. melania) are each sister to a species breeding off the coast of Peru (H. tethys and H. markhami, respectively). In fact, antitropical sister species appear to have diverged at multiple times, suggesting allochronic divergence might be common. In addition, allopatry has likely played a role in divergence of H. furcata, a north Pacific breeder, and H. pelagius, a north Atlantic breeder. This study demonstrates that a variety of mechanisms of divergence have played a role in generating the diversity of the Hydrobatinae and supports the current taxonomy of the subfamily. PMID- 27693527 TI - Effect of HFD/STZ on expression of genes involved in lipid, cholesterol and glucose metabolism in rats. AB - AIMS: The aim of the study was to evaluate lipid, cholesterol and glucose metabolism in a novel rat model of non-alcoholic fatty liver disease (NAFLD). MAIN METHODS: Rats (Wistar) were fed high fat/cholesterol diet (HFD) and a single low dose (35mg/kg) of streptozotocin (STZ). Collagen and glycogen content, oxidative stress and glucokinase activity were measured using biochemical assays. Other metabolic pathways were assessed by qRT-PCR. KEY FINDINGS: HFD/STZ treated rats, compared to control ones, showed an increase in expression of biomarkers of inflammation (TNFalpha, IL6), fibrosis (TGFbeta), mitochondrial stress (UCP2) and oxidative stress (GSH and carbonylated proteins) but not of ER stress (CHOP, XBP1). Additionally, HFD/STZ treatment caused a reduction in glycogen content, glucokinase activity (a limiting step in glycolysis) and expression of ChREBP gene (a de novo lipogenesis regulator), suggesting a modified glycolytic pathway. The cholesterol biosynthesis in HFD/STZ treated rats was inhibited (reduced expression of SREBP-2-regulated HMGCoA red and LDLr), instead the cholesterol catabolism was increased, as shown by the mRNA induction of the CYP7A1 and CYP8B1 (key genes for BA acid). A reduced gene expression of FXR-dependent SHP (a key gene for feedback inhibition of CYP7A1 and CYP8B1) and of bile acids (NTCP, OATP1A1, BSEP) and cholesterol (ABCA1) transporters was found. SIGNIFICANCE: These results widely extend the characterization of HFD/STZ rat model, which might mimic the NAFLD/NASH in diabetic humans. PMID- 27693528 TI - Inequality dynamics in the workplace among microbiologists and infectious disease specialists: a qualitative study in five European countries. AB - OBJECTIVE: To explore the social, cultural, psychological and organizational factors associated with inequality in the workplace among clinical microbiologists (CM) and infectious disease (ID) specialists in European hospitals. METHODS: We analysed data from 52 interviews and five focus groups involving 82 CM/ID specialists selected from university, research or community hospitals in five countries, one each in Northern, Western, Eastern, Southeastern and Southwestern Europe. The 80 hours of recordings were transcribed, and the anonymous database coding process was cross-checked iteratively by six researchers. RESULTS: Inequality affects all the institutions in all the countries we looked at, denying or reducing access to professional assets with intensity and form that vary largely according to the cultural and organizational context. Discrimination is generally not explicit and uses disrespectful microbehaviours that are hard to respond to when they occur. Inequality affected also loans, distribution of research funds and gender and country representation in boards and conference faculty. Parenthood has a major impact on women's careers, as women are still mainly responsible for family care. Responses to discrimination range from reactive to surrender strategies. CONCLUSIONS: Our study offers an effective model for diagnosing discriminatory behaviours in a medical professional setting. Knowledge of inequality's drivers could help national ID/CM societies in collaboration with major European stakeholders to further reduce such discrimination. The effect of discrimination on the quality of healthcare in Europe needs further exploration. PMID- 27693529 TI - Use of whole genome sequencing in the Dutch Acute HCV in HIV study: focus on transmitted antiviral resistance. AB - OBJECTIVE: Within HIV-positive men having sex with men, the epidemic of hepatitis C virus (HCV) is ongoing. Transmission of resistant variants of HCV after failure of treatment with directly acting antivirals (DAA) could be a major threat to the effectivity of therapy. We determined whether HCV-resistant variants to DAAs were prevalent amongst patients with an acute HCV infection diagnosed in 2013 and 2014 in the Netherlands. METHODS: Target enrichment for viral nucleic acid separation and deep sequencing were used to recover whole HCV genomes of 50 patients with an acute HCV infection. The genomes were assembled by de novo assembly and analysed for known DAA resistance mutations. RESULTS: In acute HCV infected treatment naive patients, the relevant resistance-associated substitutions were Q80K (40%) in NS3/4a, M28V (24%) and Q30H combined with Y93H (2%) in NS5A and M414T (2%) or S556G (2%) in NS5b. Patients whose HCV infection failed to respond to boceprevir, peginterferon and ribavirin therapy developed mutations in NS3 at position T54A and R155K. CONCLUSIONS: Target enrichment and whole genome sequencing were successfully applied directly on clinical samples from patients with an acute HCV infection.

AB - OBJECTIVES: To confirm the initial iTRAQ-based proteomic findings related to the plasma fibronectin level and hypertrophic cardiomyopathy using an antibody-based assay. METHODS: The iTRAQ technique was used for the discovery proteomic analysis of the pooled plasma samples. The ELISA was used for verification of fibronectin plasma concentration in individual samples. Additional five related plasma proteins were assessed: matrix metalloproteinase 2, matrix metalloproteinase 9, tissue inhibitor of metalloproteinase 1, tissue inhibitor of metalloproteinase 2 and brain natriuretic peptide. RESULTS: The plasma fibronectin level in patients with hypertrophic cardiomyopathy was significantly lower in comparison to the healthy subjects [215.5+/-47.3MUg/ml, n=17 vs. 376.7+/-134.8MUg/ml, n=17; p<0.0001]. CONCLUSION: In this study we present and confirm our initial proteomic findings and we suggest fibronectin as a potential indicator of an extracellular matrix remodeling related to the hypertrophic cardiomyopathy. PMID- 27693531 TI - Simultaneous screening for JAK2 and calreticulin gene mutations in myeloproliferative neoplasms with high resolution melting. AB - INTRODUCTION: Recently, novel calreticulin (CALR) mutations were discovered in Janus kinase 2 (JAK2) non-mutated myelofibrosis (PMF) and essential thrombocythemia (ET) cases, with a frequency of 60-80%. We examined clinical correlations and CALR mutation frequency in our myeloproliferative neoplasms (MPN) cases, and introduce an effective test method for use in clinical practice. METHODS: We examined 177 samples previously investigated for the JAK2 mutation for differential diagnosis of MPN. JAK2 and CALR mutations were analyzed using melting curve analysis and microchip electrophoresis, respectively. Next, we constructed a test for simultaneous screening of the JAK2 and CALR mutations utilizing high resolution melting (HRM). RESULTS: Among 99 MPN cases, 60 possessed the JAK2 mutation alone. Of the 39 MPN cases without the JAK2 mutation, 14 were positive for the CALR mutation, all of which were ET. Using our novel screening test for the JAK2 and CALR mutations by HRM, the concordance rate of conventional analysis with HRM was 96% for the JAK2 mutation and 95% for the CALR mutation. CONCLUSION: Our novel simultaneous screening test for the JAK2 and CALR gene mutations with HRM is useful for diagnosis of MPN. PMID- 27693532 TI - Sex differences on the competitive place task in the water maze: The influence of peripheral pool time on spatial navigation performance in rats. AB - This study investigated sex differences on the competitive place version of the Morris water maze task to determine whether potential strategy differences would emerge during any phase of the study but in particular on the competitive place phase. Previous findings indicate that this version of the task is highly sensitive to measures that disrupt NMDA-dependent synaptic plasticity within the hippocampus during memory consolidation (McDonald et al., 2005). The present findings revealed significant sex differences during all phases of the study, including Phase I with standard place training to located a hidden platform/goal, Phase II mass training to a new place with the platform/goal relocated to the diagonally opposite quadrant and Phase III, competitive place probe test with the platform removed to measure spatial behaviour directed at either location. The findings showed no sex difference in escape latency and other standard performance measures during the first two phases, initial place acquisition and mass training to a new location. A very subtle male advantage in visiting both Old and New place locations during the third phase place competition test was observed, however, in the time spent swimming in the periphery of the pool, the pool wall (Zone C - outer third radial distance) was increased for females during all phases of the study, suggesting a general effect may have influenced place location search behaviour of the females. Increased peripheral pool time may represent a female preference for approaching the wall, a local cue. Alternatively, the possibility that increased peripheral swimming/thigmotaxis may represent hormonal influences interacting with strategic preferences were discussed, though no definitive conclusions about sex differences in cognitive spatial performance or memory consolidation were inferred from the present findings. The findings suggest that mixed results reported in the literature by others may be due in part to an interaction with a persistent peripheral pool swimming response demonstrated in female rats. PMID- 27693533 TI - Coding and quantification of a facial expression for pain in lambs. AB - Facial expressions are routinely used to assess pain in humans, particularly those who are non-verbal. Recently, there has been an interest in developing coding systems for facial grimacing in non-human animals, such as rodents, rabbits, horses and sheep. The aims of this preliminary study were to: 1. Qualitatively identify facial feature changes in lambs experiencing pain as a result of tail-docking and compile these changes to create a Lamb Grimace Scale (LGS); 2. Determine whether human observers can use the LGS to differentiate tail docked lambs from control lambs and differentiate lambs before and after docking; 3. Determine whether changes in facial action units of the LGS can be objectively quantified in lambs before and after docking; 4. Evaluate effects of restraint of lambs on observers' perceptions of pain using the LGS and on quantitative measures of facial action units. By comparing images of lambs before (no pain) and after (pain) tail-docking, the LGS was devised in consultation with scientists experienced in assessing facial expression in other species. The LGS consists of five facial action units: Orbital Tightening, Mouth Features, Nose Features, Cheek Flattening and Ear Posture. The aims of the study were addressed in two experiments. In Experiment I, still images of the faces of restrained lambs were taken from video footage before and after tail-docking (n=4) or sham tail-docking (n=3). These images were scored by a group of five naive human observers using the LGS. Because lambs were restrained for the duration of the experiment, Ear Posture was not scored. The scores for the images were averaged to provide one value per feature per period and then scores for the four LGS action units were averaged to give one LGS score per lamb per period. In Experiment II, still images of the faces nine lambs were taken before and after tail-docking. Stills were taken when lambs were restrained and unrestrained in each period. A different group of five human observers scored the images from Experiment II. Changes in facial action units were also quantified objectively by a researcher using image measurement software. In both experiments LGS scores were analyzed using a linear MIXED model to evaluate the effects of tail docking on observers' perception of facial expression changes. Kendall's Index of Concordance was used to measure reliability among observers. In Experiment I, human observers were able to use the LGS to differentiate docked lambs from control lambs. LGS scores significantly increased from before to after treatment in docked lambs but not control lambs. In Experiment II there was a significant increase in LGS scores after docking. This was coupled with changes in other validated indicators of pain after docking in the form of pain-related behaviour. Only two components, Mouth Features and Orbital Tightening, showed significant quantitative changes after docking. The direction of these changes agree with the description of these facial action units in the LGS. Restraint affected people's perceptions of pain as well as quantitative measures of LGS components. Freely moving lambs were scored lower using the LGS over both periods and had a significantly smaller eye aperture and smaller nose and ear angles than when they were held. Agreement among observers for LGS scores were fair overall (Experiment I: W=0.60; Experiment II: W=0.66). This preliminary study demonstrates changes in lamb facial expression associated with pain. The results of these experiments should be interpreted with caution due to low lamb numbers. PMID- 27693534 TI - Age and egg-sac loss determine maternal behaviour and locomotor activity of wolf spiders (Araneae, Lycosidae). AB - Wolf spiders' (Lycosidae) maternal behaviour includes a specific phase called "egg brooding" which consists of guarding and carrying an egg-sac throughout the incubation period. The transport of an egg-sac can restrict mothers' exploratory and locomotor activity, in particular when foraging. The present study details the ontogeny of maternal behaviour and assesses the influence of age of egg-sac (or embryos' developmental stage) on vagrant wolf spider Pardosa saltans females' exploration and locomotion. We observed these spiders' maternal behaviour in the laboratory and evaluated their locomotor activity using a digital activity recording device. Our subjects were virgin females (without egg-sac) and first time mothers (with her egg-sac) who were divided into three groups. The first group of mothers were tested on the day the egg-sac was built (day 0), and the females of the other two groups were tested 10 or 15days after they had built their egg-sac. We evaluated the effects of the presence and the loss of egg-sac on mothers' activity. Pardosa saltans females' behaviour depended on mothers' physiological state and/or age of egg-sac (developmental stage of embryos). Virgin females' behaviour was not modified by the presence of an egg-sac in their environment. Mothers' reactions to the presence, the loss and the recovery of their egg-sac varied during the maternal cycle. Maternal behaviour changed with age of egg-sac, but the levels of locomotor activity of mothers with egg-sacs was similar to those of virgin females. Loss of egg-sac modified the maternal behaviour and locomotor activity of all mothers; these modifications were greater on "day 15" when embryos had emerged from eggs. All mothers were able to retrieve their egg-sacs and to re-attach them to their spinnerets. PMID- 27693535 TI - Intracranial Activity of Cabozantinib in MET Exon 14-Positive NSCLC with Brain Metastases. AB - INTRODUCTION: A significant portion of NSCLCs with MET proto-oncogene, receptor tyrosine kinase gene (MET) exon 14 skipping alterations are sensitive to small molecule mesenchymal-epithelial transition tyrosine kinase inhibitors. However, the incidence and management of brain metastases in this molecular subset is unknown and represents an unmet clinical need. METHODS: Hybrid capture-based comprehensive genomic profiling identified a patient with a MET exon 14 skipping alteration, and serial magnetic resonance imaging was utilized to follow intracranial disease during crizotinib and subsequent cabozantinib therapy. RESULTS: Intracranial progression developed in the context of ongoing extracranial disease control during crizotinib therapy. Rapid intracranial response was observed after change to cabozantinib. CONCLUSIONS: This report provides the first detailed description of brain metastases in MET exon 14 positive NSCLC and provides preliminary support for the intracranial activity of cabozantinib. Prospective study is warranted and needed to refine the management of intracranial disease in MET exon 14-positive NSCLC.

AB - Autism is a neurodevelopmental disorder categorized by qualitative impairments in social interaction, communication, and repetitive stereotypic behavior. Emerging evidence increasingly suggests that chemokine receptors have a pivotal role in the central nervous system and are involved in the pathogenesis of numerous neuroinflammatory diseases. Resveratrol is widely used to treat neurodegenerative diseases, but its effect on autism has not been investigated. We investigated the effect of resveratrol (20 and 40mg/kg) in the spleen and brain tissues of BTBR T+tf/J (BTBR) and C57BL/6J (B6) mice as well as on the C-C chemokine receptor (CCR) and C-X-C motif chemokine receptor (CXCR) (CCR3+, CCR5+, CCR7+ and CCR9+, CXCR3+ and CXCR5+) in cluster of differentiation 4-positive (CD4+) T cells in the spleen. We also assessed the mRNA expression of CCR and CXCR receptors in the spleen and brain tissues. Our study revealed that the BTBR and B6 control mice showed different immune profiles. The BTBR mice showed characteristic higher levels of both CCR and CXCR production and expression in CD4+ T cells than the B6 control mice did. Treatment of B6 and BTBR mice with resveratrol (20 and 40mg/kg) induced a substantial decrease in the CCR and CXCR production and expression in CD4+ T cells compared with the respective untreated control groups. Moreover, resveratrol treatment decreased the mRNA expression levels of CCR and CXCR in the spleen and brain tissues. Resveratrol downregulated the chemokine receptor levels, which might provide unique targets for future therapies for autism. PMID- 27693536 TI - Research for new drugs for elimination of onchocerciasis in Africa. AB - Onchocerciasis is a parasitic, vector borne disease caused by the filarial nematode Onchocerca volvulus. More than 99% of the population at risk of infection live in Africa. Onchocerciasis control was initiated in West Africa in 1974 with vector control, later complemented by ivermectin mass drug administration and in the other African endemic countries in 1995 with annual community directed treatment with ivermectin (CDTI.) This has significantly reduced infection prevalence. Together with proof-of-concept for onchocerciasis elimination with annual CDTI from foci in Senegal and Mali, this has resulted in targeting onchocerciasis elimination in selected African countries by 2020 and in 80% of African countries by 2025. The challenges for meeting these targets include the number of endemic countries where conflict has delayed or interrupted control programmes, cross-border foci, potential emergence of parasite strains with low susceptibility to ivermectin and co-endemicity of loiasis, another parasitic vector borne disease, which slows down or prohibits CDTI implementation. Some of these challenges could be addressed with new drugs or drug combinations with a higher effect on Onchocerca volvulus than ivermectin. This paper reviews the path from discovery of new compounds to their qualification for large scale use and the support regulatory authorities provide for development of drugs for neglected tropical diseases. The status of research for new drugs or treatment regimens for onchocerciasis along the path to regulatory approval and qualification for large scale use is reviewed. This research includes new regimens and combinations of ivermectin and albendazole, antibiotics targeting the O. volvulus endosymbiont Wolbachia, flubendazole, moxidectin and emodepside and discovery of new compounds. PMID- 27693538 TI - Gene expression profiling of bovine ovarian follicular and luteal cells provides insight into cellular identities and functions. AB - After ovulation, somatic cells of the ovarian follicle (theca and granulosa cells) become the small and large luteal cells of the corpus luteum. Aside from known cell type-specific receptors and steroidogenic enzymes, little is known about the differences in the gene expression profiles of these four cell types. Analysis of the RNA present in each bovine cell type using Affymetrix microarrays yielded new cell-specific genetic markers, functional insight into the behavior of each cell type via Gene Ontology Annotations and Ingenuity Pathway Analysis, and evidence of small and large luteal cell lineages using Principle Component Analysis. Enriched expression of select genes for each cell type was validated by qPCR. This expression analysis offers insight into cell-specific behaviors and the differentiation process that transforms somatic follicular cells into luteal cells. PMID- 27693539 TI - Hepatocellular carcinoma in the absence of cirrhosis in patients with chronic hepatitis B virus infection. AB - BACKGROUND & AIMS: Cirrhosis related to chronic hepatitis B (CHB) is a major risk factor for hepatocellular carcinoma (HCC). The extent to which HCC occurs in U.S. in the absence of cirrhosis in CHB remains unclear. METHODS: We identified CHB patients who were diagnosed with HCC in the national Veterans Administration (VA) between 2001 and 2013. We defined presence and absence of cirrhosis at the time of HCC diagnosis using explicit histological, radiological, endoscopic, and laboratory criteria. We used multivariable regression analysis to identify demographic and clinical characteristics associated with CHB-related HCC in the absence of cirrhosis. We also examined liver transplant-free survival in CHB-HCC patients with and without cirrhosis. RESULTS: Among 8539 CHB patients, 317 developed HCC of whom 30 (9.5%) did not have any evidence of cirrhosis at the time of HCC diagnosis. Compared to HCC patients with cirrhosis, HCC patients without cirrhosis were more likely to be non-white (African American, OR=6.78; 95% CI 2.05-22.4; Asian, OR 11.6, 95% CI 2.63-50.8), have a family history of HCC (OR 32.9, 95% CI 3.76-288), and hypertension (OR 3.15, 95% CI 1.02-9.75). There was no significant difference in the transplant-free survival between CHB-HCC patients with and without cirrhosis (hazard ratio 0.68, 95% CI 0.43-1.09). CONCLUSIONS: Fewer than 10% of U.S. based CHB-related HCC patients did not have cirrhosis. Race and family history of HCC were the main risk factors for HCC in the absence of cirrhosis in CHB. These factors may help guide the decision to initiate HCC surveillance in CHB patients without cirrhosis. LAY SUMMARY: Patients with chronic hepatitis B who are African American, or Asian, older than 40years of age with family members with liver cancer or high blood pressure are at a higher risk of developing liver cancer in the absence of cirrhosis. These patients should be included in the screening program for liver cancer. PMID- 27693540 TI - Characterization and signaling pathway analysis of interferon-kappa in bovine. AB - A bovine interferon-kappa (BoIFN-kappa) gene was amplified, which encodes a protein of 215 amino acids sharing 63% identity with human IFN-kappa. BoIFN-kappa was demonstrated to have antiviral and antiproliferative activities. Moreover, BoIFN-kappa was shown to be highly sensitive to trypsin, however, it remained stable despite changes in pH and temperature. Result showed that BoIFN-kappa can bind with bovine type I IFN receptors, and the antiviral activity can be blocked by antibodies against type I IFN receptors or BoIFN-kappa. Additionally, BoIFN kappa can induce the transcription of Mx1, ISG15 and ISG56 gene, as well as the expression of Mx1 protein. The NF-kappaB, ISRE, and BoIFN-beta promoter can all be activated by BoIFN-kappa. This study revealed that BoIFN-kappa exhibits the typical characteristics of type I IFNs and exerts antiviral activity via activation of the JAK-STAT signaling pathway. Overall, these findings will enrich the current knowledge about IFN-kappa and facilitate further research on the role of type I IFN in antiviral defense responses in bovine. PMID- 27693542 TI - The role of Fusobacterium necrophorum in pharyngotonsillitis - A review. AB - Fusobacterium necrophorum is a gram-negative anaerobic bacterium that is the causative agent of the invasive disease Lemierre's syndrome. In addition, it is also associated with peritonsillar abscess formation and otitis media in small children. Recent research has shown that F. necrophorum may be involved in pharyngotonsillitis especially in adolescent and young adults and that it may be the second most common bacterial cause of pharyngotonsillitis after Streptococcus pyogenes (Group A streptococci). Peritonsillar abscesses and Lemierre's syndrome due to F. necrophorum are also found in this age group, suggesting that they may be complications of F. necrophorum pharyngotonsillitis. In this review we present the present knowledge about the role of F. necrophorum in pharyngotonsillitis with special emphasis on the age distribution. We argue that F. necrophorum is an important pathogen involved in pharyngotonsillitis in the age group of 13-40 years of age and we urge clinical microbiology labs to set up the appropriate techniques to be able to detect F. necrophorum from throat swabs.

AB - INTRODUCTION: Spread through air spaces (STAS) is a recently recognized pattern of invasion in lung adenocarcinoma; however, it has not yet been characterized in squamous cell carcinoma (SCC). METHODS: We reviewed 445 resected stage I to III lung SCCs and investigated the clinical significance of STAS. Cumulative incidence of recurrence and lung cancer-specific death were evaluated by competing risks analyses and overall survival by Cox models. RESULTS: Of the total 445 patients, 336 (76%) were older than 65 years. Among the 273 patients who died, 91 (33%) died of lung cancer whereas the remaining ones died of competing events or unknown cause. STAS was observed in 132 patients (30%) and the frequency increased with stage. The cumulative incidences of any, distant, and locoregional recurrence as well as lung cancer-specific death were significantly higher in patients with STAS compared with in those without STAS, whereas there was no statistically significant difference in overall survival. In multivariable models for any recurrence and lung cancer-specific death, STAS was an independent predictor for both outcomes (p = 0.034 and 0.016, respectively). CONCLUSION: STAS was present in one-third of resected lung SCCs. In competing risks analysis in a cohort in which three-fourths of the patients were elderly, STAS was associated with lung cancer-specific outcomes. Our findings suggest that STAS is one of the most prognostically significant histologic findings in lung SCC. PMID- 27693543 TI - Clostridium difficile: A rare cause of pyogenic liver abscess. AB - Extra-intestinal infections due to Clostridium difficile have been reported rarely. Herein we report a case of pyogenic liver abscess from toxigenic C. difficile in an 80-year-old non-hospitalized woman with diabetes mellitus, cerebrovascular and cardiovascular diseases. The patient was admitted to the emergency department with fever and abdominal pain. There was no history of diarrhea or use of antibiotics. Laboratory parameters revealed signs of inflammation and elevated AST and ALT levels. Abdominal ultrasound and computer tomography showed multiple focal lesions in the bilateral liver lobes and hydropic gallbladder with stones. The patient underwent cholecystectomy and the liver abscesses were drained. Toxigenic C. difficile strains were isolated from the drained pus and also from the stool sample. According to repetitive-element PCR (rep-PCR) analyses both organisms were the same. The organisms were susceptible to antibiotics. Despite proper antibiotic therapy and surgical drainage, the patient succumbed to her illness. PMID- 27693544 TI - Bypass graft infection and bacteremia caused by Anaerostipes caccae: First report of human infection caused by a recently described gut anaerobe. AB - We report a case of bypass graft infection and bacteremia caused by Anaerostipes caccae. A review of the literature shows no reported human infection caused by this microorganism to date. The patient was initially treated with vancomycin and piperacillin-tazobactam on admission and with amoxicillin-clavulanate upon discharge. The slow-growing organism was subsequently found to be susceptible to metronidazole and ertapenem. PMID- 27693545 TI - Controlled bone formation using ultrasound-triggered release of BMP-2 from liposomes. AB - Recombinant human bone morphogenetic protein 2 (rhBMP-2) is used clinically to enhance implant-mediated bone regeneration. However, there are risks associated with the high rhBMP-2 dose that is required in the implant to mitigate diffusional loss over the therapeutic timespan. On-demand, localized control over delivery of rhBMP-2, days after implantation, would therefore be an attractive solution in the area of bone repair and reconstruction, yet this has posed a significant challenge, with little data to support in vivo efficacy to date. To address this, we have developed novel liposome-rhBMP-2 nanocomplexes that release rhBMP-2 in response to non-thermogenic, clinical diagnostic ultrasound exposure. In vitro validation shows that rhBMP-2 release is in proportion to applied ultrasound pressure and duration of exposure. Moreover, here we show in vivo validation of this ultrasound-triggered rhBMP-2 delivery system in a standard mouse bone regeneration model. Implanted into hindleg muscles, the liposome-rhBMP 2 nanocomplexes induced local bone formation only after ultrasound exposure. Such post-implantation control of delivery has potential to improve the safety, efficacy and cost of rhBMP-2 use in bone reconstruction. Furthermore, this first proof-of-concept demonstration of in vivo efficacy for ultrasound-triggered liposomal delivery of rhBMP-2 has broader implications for tunable delivery of a variety of drugs and biologics in medicine and tissue engineering. PMID- 27693546 TI - An acute, non-therapeutic dose of methylphenidate disrupts partner preference in female rats. AB - The present study was designed to test the effects of an acute, high dose of methylphenidate (MPH; trademarked as Ritalin) on sexual behavior in female Long Evans rats. In Experiment 1, naturally cycling subjects in estrus were tested for partner preference 20min after receiving an i.p. injection of MPH 10mg/kg (n=8) or saline (n=7). During the partner-preference test, female subjects were given the choice to interact with a sexually active male stimulus or a sexually receptive female stimulus. Physical contact was limited by placing the stimulus animals behind a wire mesh during the no-contact phase of the test, whereas physical contact was not limited during the contact phase. Female subjects that received MPH spent significantly less time with the male stimulus than the saline treated subjects during both phases (no-contact and contact) of the partner preference test. This acute dose of MPH did not affect visits to the female stimulus; however, MPH-treated subjects made fewer visits to the male stimulus than the saline-treated subjects during the contact phase of the partner preference test. Consistent with previous findings, MPH increased line crossings when subjects were tested in an open field immediately after the partner preference test. In Experiment 2, female subjects were ovariectomized (OVX), primed with estradiol benzoate and progesterone, and tested for partner preference 20min after receiving an injection of MPH 10mg/kg (n=8) or saline (n=8). Similar to the results of Experiment 1, OVX hormone-primed subjects that received MPH spent significantly less time with the male stimulus than the saline treated subjects during both phases of the partner-preference test. Although MPH treated subjects were sexually receptive, they displayed fewer proceptive behaviors (i.e., hops and darts) than saline-treated subjects. Two-weeks later, the subjects from Experiment 2 were tested in an open field 20min after receiving an injection of MPH 10mg/kg or saline (counterbalancing previous MPH exposure). Once again MPH increased locomotor activity. In conclusion, the effects of MPH were equally as robust in naturally cycling subjects as in the more commonly used OVX-hormone primed subjects. The results of the present study suggest that an acute, non-therapeutic dose of MPH disrupts approach and interest in a male stimulus during a test of partner preference. This avoidance of the male stimulus may be the result of a decrease in the incentive value of a sexual partner. PMID- 27693547 TI - Meditation and auditory attention: An ERP study of meditators and non-meditators. AB - The findings of a study by Cahn and Polich (2009) suggests that there is an effect of a meditative state on three event-related potential (ERP) brain markers of "low-level" auditory attention (i.e., acoustic representations in sensory memory) in expert meditators: the N1, the P2, and the P3a. The current study built on these findings by examining trait and state effects of meditation on the passive auditory mismatch negativity (MMN), N1, and P2 ERPs. We found that the MMN was significantly larger in meditators than non-meditators regardless of whether they were meditating or not (a trait effect), and that N1 amplitude was significantly attenuated during meditation in non-meditators but not expert meditators (an interaction between trait and state). These outcomes suggest that low-level attention is superior in long-term meditators in general. In contrast, low-level attention is reduced in non-meditators when they are asked to meditate for the first time, possibly due to auditory fatigue or cognitive overload. PMID- 27693550 TI - Fabrication of layered (CdS-Mn/MoS2/CdTe)-promoted TiO2 nanotube arrays with superior photocatalytic properties. AB - A novel (CdS-Mn/MoS2/CdTe)-sensitized TiO2 nanotube arrays (NTAs) photoelectrode has been prepared by electrodeposite, successive ionic layer adsorption and reaction (SILAR) coupled with hydrothermal method. When a ZnS layer was added on the top of CdS-Mn/MoS2/CdTe/TiO2, a notable red-shift and high absorption was observed in the visible light region. The photocurrent density (mA/cm2) systematically increases from TiO2 NTAs (0.43), CdTe/TiO2 (1.09), MoS2/CdTe/TiO2 (1.80), CdS-Mn/MoS2/CdTe/TiO2 (2.40), to ZnS/CdS-Mn/MoS2/CdTe/TiO2 (3.41) under visible light irradiation, due to the type-II semiconductor heterostructures comprising multiple components with a staggered band offset. Such a heterostructure possesses an enhanced photocatalytic performance towards degradation of organic contaminant, e.g. P-Nitrophenol (PNP) and Rhodamine B (RhB). PMID- 27693549 TI - Pharmacologic antagonism of dopamine receptor D3 attenuates neurodegeneration and motor impairment in a mouse model of Parkinson's disease. AB - Neuroinflammation involves the activation of glial cells, which is associated to the progression of neurodegeneration in Parkinson's disease. Recently, we and other researchers demonstrated that dopamine receptor D3 (D3R)-deficient mice are completely refractory to neuroinflammation and consequent neurodegeneration associated to the acute intoxication with 1-methyl-4-phenyl-1,2,3,6 tetrahydropyridine (MPTP). In this study we examined the therapeutic potential and underlying mechanism of a D3R-selective antagonist, PG01037, in mice intoxicated with a chronic regime of administration of MPTP and probenecid (MPTPp). Biodistribution analysis indicated that intraperitoneally administered PG01037 crosses the blood-brain barrier and reaches the highest concentration in the brain 40 min after the injection. Furthermore, the drug was preferentially distributed to the brain in comparison to the plasma. Treatment of MPTPp intoxicated mice with PG01037 (30 mg/kg, administrated twice a week for five weeks) attenuated the loss of dopaminergic neurons in the substantia nigra pars compacta, as evaluated by stereological analysis, and the loss of striatal dopaminergic terminals, as determined by densitometric analyses of tyrosine hydroxylase and dopamine transporter immunoreactivities. Accordingly, the treatment resulted in significant improvement of motor performance of injured animals. Interestingly, the therapeutic dose of PG01037 exacerbated astrogliosis and resulted in increased ramification density of microglial cells in the striatum of MPTPp-intoxicated mice. Further analyses suggested that D3R expressed in astrocytes favours a beneficial astrogliosis with anti-inflammatory consequences on microglia. Our findings indicate that D3R-antagonism exerts a therapeutic effect in parkinsonian animals by reducing the loss of dopaminergic neurons in the nigrostriatal pathway, alleviating motor impairments and modifying the pro-inflammatory phenotype of glial cells. PMID- 27693551 TI - Self-assembled structures and excellent surface properties of a novel anionic phosphate diester surfactant derived from natural rosin acids. AB - A novel anionic rosin-based phosphate diester sodium (DDPDS) was successfully synthesized from raw dehydroabietic acid, a natural raw material, via four-step reactions: acylation, esterification, phosphorylation and neutralization. Nuclear magnetic resonance (13C NMR) and Fourier transform infrared spectroscopy (FT-IR) were used to characterize the structure of target products. The aggregation behaviors in aqueous-ethanol solution and surface properties of DDPDS and its mixed systems were investigated by transmission electron microscopy (TEM), automatic tensiometer and contact angle measuring instrument. The results showed that DDPDS had high surface activity, unexpected emulsification and excellent wettability. The critical micelle concentration (CMC) of 1.35g*L-1, the minimum surface tension (gammacmc) of 31.75mN*m-1, emulsifying power of 153s and the minimum contact angle of 13.4 degrees were determined for DDPDS. Spherical vesicles with diameter about 50nm and 5MUm were self-assembled respectively in aqueous-ethanol solution when DDPDS concentration is about 1 CMC and 5 CMC. Two surfactant ionic self-assembly systems were constructed by mixing DDPDS with sodium dodecylbenzenesulfonate (SDBS) and cetyltrimethylammonium bromide (CTAB), which forms 40nm and 20nm spherical micelles in 1 CMC aqueous-ethanol solution. Possible formation mechanisms of surfactant ionic self-assembly systems on a combination of ionic interactions between DDPDS and SDBS or CTAB are discussed. It was found that there were an obvious synergistic effect of foam stability in DDPDS/SDBS mixed system and an obvious synergistic effect of foam capability in DDPDS/CTAB mixed system. PMID- 27693548 TI - Towards Personalized Intervention for Alzheimer's Disease. AB - Alzheimer's disease (AD) remains to be a grand challenge for the international community despite over a century of exploration. A key factor likely accounting for such a situation is the vast heterogeneity in the disease etiology, which involves very complex and divergent pathways. Therefore, intervention strategies shall be tailored for subgroups of AD patients. Both demographic and in-depth information is needed for patient stratification. The demographic information includes primarily APOE genotype, age, gender, education, environmental exposure, life style, and medical history, whereas in-depth information stems from genome sequencing, brain imaging, peripheral biomarkers, and even functional assays on neurons derived from patient-specific induced pluripotent cells (iPSCs). Comprehensive information collection, better understanding of the disease mechanisms, and diversified strategies of drug development would help with more effective intervention in the foreseeable future. PMID- 27693552 TI - Protein oleogels from heat-set whey protein aggregates. AB - In this research we use heat-set whey protein aggregates (diameter~200nm) as novel building blocks for structure formation in liquid oil to form oleogels. To transfer the aggregates to the oil phase, a solvent exchange procedure to sunflower oil was applied using acetone as an intermediate solvent. We found that agglomeration of the aggregates was prevented and the particle size in oil did not change from that in the initial aqueous phase. The small protein aggregates assemble into a space-spanning network, thereby providing solid-like properties to liquid oil. From oscillatory rheology we conclude that the aggregates are highly effective in forming a network. Already at ~3% we found that G'>G" and G' scales with protein concentration as G'~cp5.3. Applying a fractal gel network theory to the rheological data we deduce that the gels are in the strong link regime with a fractal dimension of 2.2. The results show that protein aggregates, besides their well-known functionality in aqueous solvents, are capable of forming a network in liquid oil. This provides a novel and promising way to design oleogels with tuneable rheological properties, applicable to e.g. foods, pharmaceuticals and/or cosmetics. PMID- 27693553 TI - Natural polysaccharides-modified graphene oxide for adsorption of organic dyes from aqueous solutions. AB - Three polysaccharide- graphene oxide composite materials (PS-GO) were synthesized from graphene oxide (GO) and natural polysaccharides, which compounds were tested for removal of organic dyes from aqueous solutions. These adsorbents were characterized by Fourier transform infrared spectroscopy (FT-IR), Raman spectrometer, X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), N2 adsorption-desorption isotherms and UV-vis spectrum. The adsorption properties of PS-GO towards four organic dyes were investigated along with measured effects on adsorption by initial concentration, temperature, contact time and pH value. Resulting adsorption isotherms, thermodynamics and kinetics were analyzed systematically. In these tests, PS-GO composite materials were found to be more efficient than as-prepared GO as adsorbents for the removal of both cationic and anionic organic dyes. PMID- 27693554 TI - Mechanochemical approach for the capping of mixed core CdS/ZnS nanocrystals: Elimination of cadmium toxicity. AB - The wet mechanochemical procedure for the capping of the CdS and CdS/ZnS quantum dot nanocrystals is reported. l-cysteine and polyvinylpyrrolidone (PVP) were used as capping agents. When using l-cysteine, the dissolution of cadmium(II) was almost none for CdS/ZnS nanocrystals. Moreover, prepared CdS- and CdS/ZnS cysteine nanosuspensions exhibited unimodal particle size distributions with very good stability, which was further supported by the zeta potential measurements. The Fourier-transform infrared (FTIR) and nuclear magnetic resonance (NMR) spectroscopy showed the successful embedment of cysteine into the structure of the nanocrystals. Additionally, the optical properties were examined, and the results showed that the cysteine nanosuspension has promising fluorescence properties. On the other hand, PVP was not determined to be a very suitable capping agent for the present system. In this case, the release of cadmium(II) was higher in comparison to the l-cysteine capped samples. The nanosuspensions were successfully used for in vitro studies on selected cancer cell lines. Using fluorescence microscopy, it was evidenced that the nanocrystals enter the cell and that they can serve as imaging agents in biomedical applications. PMID- 27693555 TI - Translating leukemia stem cells into the clinical setting: Harmonizing the heterogeneity. AB - Considerable evidence suggests that rare leukemia cells with stem cell features, including self-renewal capacity and drug resistance, are primarily responsible for both disease maintenance and relapses. Traditionally, these so-called leukemia stem cells (LSCs) have been identified in the laboratory by their ability to engraft acute myeloid leukemia (AML) into immunocompromised mice. For many years, only those rare AML cells characterized by a hematopoietic stem cell (HSC) CD34+CD38- phenotype were believed capable of generating leukemia in immunocompromised mice. However, more recently, significant heterogeneity in the phenotypes of those AML cells that can engraft immunocompromised mice has been demonstrated. AML cells that engraft immunocompromised mice have also been shown to not necessarily represent either the founder clone or those cells responsible for relapse. A recent study found that the most immature phenotype present in an AML correlated with genetically defined risk groups and outcomes, but was heterogeneous. Patients with AML cells expressing a primitive HSC phenotype (CD34+CD38- with high aldehyde dehydrogenase activity) manifested significantly lower complete remission rates, as well as poorer event-free and overall survivals. Leukemias in which the most primitive cells displayed more mature phenotypes were associated with better outcomes. The strong clinical correlations suggest that the most immature phenotype detectable within a patient's AML might serve as a biomarker for "clinically relevant" LSCs. PMID- 27693557 TI - Dye-conjugated single-walled carbon nanotubes induce photothermal therapy under the guidance of near-infrared imaging. AB - Recently, photothermal therapy (PTT) has become viewed as an ideal auxiliary therapeutic treatment for cancers. However, the development of safe, convenient, and highly effective photothermal agents remains a great challenge. In this study, we prepared single-walled carbon nanotubes (SWNTs) for PTT against breast tumors under the guidance of infrared fluorescent cyanines. Tumors were accurately located using near-infrared imaging (NIR) and then exposed to laser irradiation. Both the in vivo and in vitro results showed that the SWNTs have high stability and low cytotoxicity. Introducing polyethylene glycol into our nanoparticles increased the blood-circulation time. Our in vivo results further showed that Cy5.5-conjugated SWNTs mediated PTT, resulting in efficient tumor suppression in mice under the guidance of near-infrared imaging. Due to the small amount of absorption at 808-nm, Cy5.5 increased the efficiency of PTT. Breast tumors significantly shrunk after irradiation under the 808-nm near-infrared laser. The treated mice developed scabs, but otherwise recovered after 15 days, and their physical conditions restored gradually. These data indicate that our unique photothermal-responsive SWNT-Cy5.5-based theranostic agent can serve as a promising candidate for PTT. PMID- 27693558 TI - Lgr4 is crucial for skin carcinogenesis by regulating MEK/ERK and Wnt/beta catenin signaling pathways. AB - Lgr4 is a member of the leucine-rich, G protein-coupled receptor family of proteins, and has recently been shown to augment Wnt/beta-catenin signaling via binding to Wnt agonists R-spondins. It plays an important role in skin development, but its involvement in skin tumorigenesis is unclear. Here, we report that mice deficient for Lgr4 are resistant to 12-O-tetradecanoyl-phorbol 13-acetate (TPA)-induced keratinocyte proliferation and papilloma formation. We show that TPA treatment activates MEK1, ERK1/2 and downstream effector AP-1 in wild-type (WT) epidermal cells and mice, but not in cells or mice where Lgr4 is depleted. Wnt/beta-catenin signaling is also dramatically activated by TPA treatment, and this activation is abolished when Lgr4 is deleted. We provide evidences that blocking both MEK1/ERK1/2 and Wnt/beta-catenin pathways prevents TPA-induced increase in the expression of Ccnd1 (cyclin D1), a known Wnt/beta catenin target gene, and that the activation of MEK1/ERK1/2 pathway lies upstream of Wnt/beta-catenin signal pathway. Collectively, our findings identify Lgr4 as a critical positive factor for skin tumorigenesis by mediating the activation of MEK1/ERK1/2 and Wnt/beta-catenin pathways. PMID- 27693559 TI - Morphology and molecular phylogeny of a new Myxidium species (Cnidaria: Myxosporea) infecting the farmed turtle Podocnemis expansa (Testudines: Podocnemididae) in the Brazilian Amazon. AB - This study reports, for the first time, a myxosporan species of the genus Myxidium in a Neotropical turtle. Myxidium turturibus n. sp., was found in the gall bladder of Podocnemis expansa (Testudines: Podocnemididae) farmed in Brazilian Amazon. Numerous disporic pseudoplasmodia in different developmental stages, and mature spores were free in the bile. Mature myxospores were fusiform, slightly arcuate in valval view, measuring 13.6+/-0.4 (13.1-15.1) MUm in length and 4.1+/-0.3 (3.4-4.6) MUm in width. The two polar capsules were piriform, with 3.4+/-0.4 (2.5-4.0) MUm in length and 2.4+/-0.4 (1.5-2.7) MUm in width and had five to six polar filament turns. Phylogenetic analysis inferred by 18S rDNA shows the new species closely related with M. hardella and M. chelonarum, which are parasites of freshwater/terrestrials turtles from Oriental Region. PMID- 27693556 TI - Anti-tumor activity of selective inhibitor of nuclear export (SINE) compounds, is enhanced in non-Hodgkin lymphoma through combination with mTOR inhibitor and dexamethasone. AB - In previous studies we demonstrated that targeting the nuclear exporter protein exportin-1 (CRM1/XPO1) by a selective inhibitor of nuclear export (SINE) compound is a viable therapeutic strategy against Non-Hodgkin Lymphoma (NHL). Our studies along with pre-clinical work from others led to the evaluation of the lead SINE compound, selinexor, in a phase 1 trial in patients with CLL or NHL (NCT02303392). Continuing our previous work, we studied combinations of selinexor dexamethasone (DEX) and selinexor-everolimus (EVER) in NHL. Combination of selinexor with DEX or EVER resulted in enhanced cytotoxicity in WSU-DLCL2 and WSU FSCCL cells which was consistent with enhanced apoptosis. Molecular analysis showed enhancement in the activation of apoptotic signaling and down-regulation of XPO1. This enhancement is consistent with the mechanism of action of these drugs in that both selinexor and DEX antagonize NF-kappaB (p65) and mTOR (EVER target) is an XPO1 cargo protein. SINE compounds, KPT-251 and KPT-276, showed activities similar to CHOP (cyclophosphamide-hydroxydaunorubicin-oncovin prednisone) regimen in subcutaneous and disseminated NHL xenograft models in vivo. In both animal models the anti-lymphoma activity of selinexor is enhanced through combination with DEX or EVER. The in vivo activity of selinexor and related SINE compounds relative to 'standard of care' treatment is consistent with the objective responses observed in Phase I NHL patients treated with selinexor. Our pre-clinical data provide a rational basis for testing these combinations in Phase II NHL trials. PMID- 27693560 TI - Differential distribution and biochemical characteristics of hydrolases among developmental stages of Schistosoma mansoni may offer new anti-parasite targets. AB - Schistosoma mansoni enzymes play important roles in host-parasite interactions and are potential targets for immunological and/or pharmacological attack. The aim of this study was to comparatively assess the presence of hydrolytic activities (phosphatases, glycosidases, aminopeptidases) in soluble (SF) and membrane (MF) fractions from different S. mansoni developmental stages (schistosomula 0 and 3h, juveniles, and adult worms of 28 and 45days-old, respectively), by using simple enzyme-substrate microassays. Our results show and confirm the prominent presence of alkaline phosphatase (AlP) activity in the MF of all the above parasite stages, highlighting also the relevant presence of MF associated alpha-mannosidase (alpha-MAN) activity in juveniles. A soluble AlP activity, together with beta-N-D-acetylglucosaminidase (beta-NAG), and alpha-MAN activities, was detected in SF of schistosomulum 0h. Soluble beta-NAG, alpha-MAN, acid phosphatase (AcP), leucin (LAP) and alanine (AAP) aminopeptidase activities were also seen in the SF of the other different developmental stages. This work shows different soluble and membrane-associated hydrolytic capacities in each S. mansoni developmental stage from schistosomula to adults that might be exploitable as potential new targets for immune and/or chemoprophylactic strategies. PMID- 27693561 TI - Transplantation of Cardicola opisthorchis (Trematoda: Aporocotylidae) sporocysts into the intermediate host, Terebella sp. (Polychaeta: Terebellidae). AB - Cardicola opisthorchis is a blood fluke pathogen significantly affecting cultured Pacific bluefin tuna Thunnus orientalis in Japan. It is known that the intermediate host of C. opisthorchis is a terebellid polychaete Terebella sp. In order to study the intrapolychaete larval development of C. opisthorchis, we transplanted sporocysts, which contained a large number of cercariae, of C. opisthorchis obtained from Terebella sp. into sporocyst-free Terebella sp., which had been maintained at 20 degrees C. The transplanted sporocysts switched from cercarial to sporocystal production by 17days after transplantation (d.a.t.) and daughter sporocysts were released into the polychaete body cavity at 25d.a.t. Subsequently, the released daughter sporocysts produced daughter sporocysts again. Thereafter, daughter sporocysts that contained cercariae appeared at 38d.a.t. and gradually increased. At 51d.a.t., 136 sporocysts that had multiplied from the original two transplanted sporocysts were observed in the body of one polychaete, and cercariae were released from daughter sporocysts inside the polychaete body cavity. Subsequently the cercariae were found to be released outside the polychaete at 57d.a.t. This is the first successful case of in situ observation of the development of a blood fluke within the intermediate host. PMID- 27693562 TI - Editorial: 3rd Special Issue on behavior change, health, and health disparities. AB - This Special Issue of Preventive Medicine (PM) is the 3rd that we have organized on behavior change, health, and health disparities. This is a topic of critical importance to improving U.S. population health. There is broad scientific consensus that personal behaviors such as cigarette smoking, other substance abuse, and physical inactivity/obesity are among the most important modifiable causes of chronic disease and its adverse impacts on population health. Hence, effectively promoting health-related behavior change needs to be a key component of health care research and policy. There is also broad recognition that while these problems extend throughout the population, they disproportionately impact economically disadvantaged populations and other vulnerable populations and represent a major contributor to health disparities. Thus, behavior change represents an essential step in curtailing health disparities, which receives special attention in this 3rd Special Issue. We also devote considerable space to the longstanding challenges of reducing cigarette smoking and use of other tobacco and nicotine delivery products in vulnerable populations, obesity, and for the first time food insecurity. Across each of these topics we include contributions from highly accomplished policymakers and scientists to acquaint readers with recent accomplishments as well as remaining knowledge gaps and challenges. PMID- 27693563 TI - Biomechanical arrangement of threaded and unthreaded portions providing holding power of transpedicular screw fixation. AB - BACKGROUND: Failure of pedicle screw is a major concern in spinal surgery. The threaded and unthreaded portions of the pedicle screw provide the ability to anchor and squeeze the surrounding bone, respectively. This study aimed to investigate the anchoring and squeezing effects of different design of the threaded/unthreaded portions of a pedicle screw to vertebrae. METHODS: Four variations (one fully and three partially threaded, with a 1/3, 1/2, and 2/3 unthreaded designs at the proximal portion) of screws were used to measure pullout strength and withdrawn energy using synthetic and porcine specimens. The tests were conducted in static and dynamic fashions, in that the screws were axially extracted directly and after 150,000cycles of lateral bending. The load displacement curves were recorded to gain insight into the peak load (pullout strength) and cumulative work (withdrawn energy). FINDINGS: The two testing results of the synthetic and porcine specimens consistently showed that the 1/3 unthreaded screw provides significantly higher pullout strength and withdrawn energy than the fully threaded screw. The withdrawn energy of the three unthreaded screws was significantly higher than that of the threaded counterpart. INTERPRETATION: The holding power of a pedicle screw was the integration of the anchoring (cancellous core) and squeezing (compact pedicle) effects within the threaded and unthreaded portions. The current study recommends the 1/3 unthreaded screw as an optimal alternative for use as a shank-sliding mechanism to preserve the holding power within the pedicle isthmus.

Elderly people want to live independently in their home environment for as long as possible. However, as we age, our physical skills tend to worsen and our social circle tends to become smaller, something that often leads to a considerable decrease of both our physical and social activities. In this paper, we present an AAL framework developed within the SONOPA project, whose objective is to promote active ageing by combining a social network with information inferred using in-home sensors. PMID- 27693565 TI - The Learning Healthcare System: Where are we now? A systematic review. AB - BACKGROUND AND OBJECTIVE: The Learning Healthcare System paradigm has attracted the attention of researchers worldwide. The great potential originating from high scale health data reuse and the inclusion of patient perspectives into care models promises personalized care, lower costs of health services and minimized consumption of resources. The aim of this review is to summarize the attempts to adopt the novel paradigm, putting emphasis on implementations and evaluating the impact on current medical practices. METHOD: PRISMA methodology was followed for structuring the review process. Three major research databases (PubMed, IEEE Xplore and ACM DL) were queried with the predefined search terms "learning healthcare" and "learning health". Publications containing specific theoretical or empirical results were considered. RESULTS: Three hundred and fifty-eight publications were identified; however, only 32 met the inclusion criteria. Nineteen papers were characterized as theoretical contributions, while the rest presented empirical achievements. Only one paper described the initial estimates of impact and economy. DISCUSSION: Individualistic communication of studies ignoring popular frameworks for assessing and reporting research achievements prevents the systematic generation of knowledge. Evaluating the impact of the Learning Healthcare System instances where it is implemented could work as a catalyst in reaching higher acceptance and adoption of the proposed ideas by healthcare worldwide; however, it mostly remains described in theory. CONCLUSIONS: The review demonstrated the interest of researchers in exploring the Learning Healthcare System ideas. However, it also revealed minimal focus on evaluating the impact of the novel paradigm on both healthcare service delivery and patient outcome.

AB - Poloxamer 188 (P188) has been reported to reseal plasma membranes and attenuate TBI-induced neuronal death by suppressing apoptosis. Recent studies also confirm increased autophagy after traumatic brain injury (TBI). The present study aimed to investigate the effects of plasmalemmal resealing by P188 on neuronal autophagy in TBI. Scratch test was performed in rat cell line PC-12 in vitro, followed by immunofluorescence analysis of LC3 24h after PC-12 cell stretch injury in vitro. CD1 mice were randomized into saline and P188-treatment groups (both undergoing intravenous injection of 4mg/ml, 100MUl via the caudal vein 30min after TBI) as well as sham group. To analyze the effect of P188 on autophagy, the LC3 protein levels were assessed by western blotting 1h, 6h, 12h, 24h, and 48h after TBI. The autophagy-associated protein levels of Beclin-1, Bcl 2, and p62 were likewise determined. In vitro, the scratch test showed that the wound healing rate was significantly improved at 12h and 24h in P188 groups, and LC3 immunofluorescence analysis indicated that P188 induced extensive formation of LC3 puncta in PC-12 cells. In vivo, western blotting analyses revealed elevations of the LC3-II/LC3-I and Beclin-1/bcl-2 ratios as well as downregulation of p62 in the saline group, in contrast with the more significant increases of LC3-II/LC3-I and Beclin-1/bcl-2 ratios and the further downregulation of p62 in P188-treated group. These results revealed that plasma membranes were resealed after TBI, in which P188 aggravated autophagy in vivo.

AB - While an injury to the central nervous system (CNS) in humans and mammals is irreversible, amphibians and teleost fish have the capacity to fully regenerate after severe injury to the CNS. Xenopus laevis has a high potential to regenerate the brain and spinal cord during larval stages (47-54), and loses this capacity during metamorphosis. The optic nerve has the capacity to regenerate throughout the frog's lifespan. Here, we review CNS regeneration in frogs, with a focus in X. laevis, but also provide some information about X. tropicalis and other frogs. We start with an overview of the anatomy of the Xenopus CNS, including the main supraspinal tracts that emerge from the brain stem, which play a key role in motor control and are highly conserved across vertebrates. We follow with the advantages of using Xenopus, a classical laboratory model organism, with increasing availability of genetic tools like transgenesis and genome editing, and genomic sequences for both X. laevis and X. tropicalis. Most importantly, Xenopus provides the possibility to perform intra-species comparative experiments between regenerative and non-regenerative stages that allow the identification of which factors are permissive for neural regeneration, and/or which are inhibitory. We aim to provide sufficient evidence supporting how useful Xenopus can be to obtain insights into our understanding of CNS regeneration, which, complemented with studies in mammalian vertebrate model systems, can provide a collaborative road towards finding novel therapeutic approaches for injuries to the CNS.

AB - Inflammatory pain and neuropathic pain are major clinical health issues that represent considerable social and economic burden worldwide. In the present study, we investigated the anti-nociceptive efficacy of delivery of human proenkephalin gene by a plasmid DNA vector (pVAX1-PENK) on complete Freund's adjuvant (CFA) induced inflammatory pain and spared nerve injury (SNI) induced neuropathic pain in mice. Mice were intramuscularly or intrathecally administered pVAX1 or pVAX1-PENK, respectively. Pain thresholds in the pVAX1-PENK treated mice were significantly higher at day 3, then reached a peak at day 7 and lasted until day 28 after gene transfer, and the analgesic effect of pVAX1-PENK was blocked with naloxone hydrochloride. In contrast, pVAX1 treated mice did not significantly improve pain thresholds. These results indicate that peripheral or spinal delivery of a plasmid encoding human proenkephalin gene provides a potential therapeutic strategy for inflammatory pain and neuropathic pain. PMID- 27693569 TI - Accurate annotation of protein-coding genes in mitochondrial genomes. AB - Mitochondrial genome sequences are available in large number and new sequences become published nowadays with increasing pace. Fast, automatic, consistent, and high quality annotations are a prerequisite for downstream analyses. Therefore, we present an automated pipeline for fast de novo annotation of mitochondrial protein-coding genes. The annotation is based on enhanced phylogeny-aware hidden Markov models (HMMs). The pipeline builds taxon-specific enhanced multiple sequence alignments (MSA) of already annotated sequences and corresponding HMMs using an approximation of the phylogeny. The MSAs are enhanced by fixing unannotated frameshifts, purging of wrong sequences, and removal of non-conserved columns from both ends. A comparison with reference annotations highlights the high quality of the results. The frameshift correction method predicts a large number of frameshifts, many of which are unknown. A detailed analysis of the frameshifts in nad3 of the Archosauria-Testudines group has been conducted. PMID- 27693570 TI - Gene duplication and concerted evolution of mitochondrial DNA in crane species. AB - The gene duplication in mitochondrial DNA (mtDNA) has been reported in diverse bird taxa so far. Although many phylogenetic and population genetic analyses of cranes were carried out based on mtDNA diversity, whether mtDNA contains duplicated regions is unknown. To address the presence or absence of gene duplication in cranes and investigate the molecular evolutionary features of crane mtDNA, we analyzed the gene organization and the molecular phylogeny of mtDNA from 13 crane species. We found that the mtDNA in 13 crane species shared a tandem duplicated region, which consists of duplicated sequence sets including cytochrome b (Cytb), NADH6, control region (CR) and three genes of tRNA. The gene order in the duplicated region was identical among all the 13 crane species, and the nucleotide sequences found within each individual showed high similarities. In addition, phylogenetic trees based on homologous sequences of CR and Cytb indicated the possibility of concerted evolution among the duplicated genes. The results suggested that the duplication event occurred in the common ancestor of crane species or some older ancestors. PMID- 27693571 TI - Better Defining the Spectrum of Adult Hypospadias: Examining the Effect of Childhood Surgery on Adult Presentation. AB - OBJECTIVE: To describe the spectrum of adult presentations with hypospadias related complications and examine the effect of childhood surgical repair on these adult presentations. METHODS: A retrospective chart review over a 10-year period, from August 2004 to December 2014, demonstrated 93 adult patients who presented to a reconstructive urologist with complications related to hypospadias. Patients were divided into 2 groups: those with no prior hypospadias surgery (Group 1, N = 19) and those who underwent surgical correction as a child (Group 2, N = 74). Charts were reviewed for age at presentation, initial complaints, history of repair, and surgical intervention required. RESULTS: The mean age at presentation was 34.6 +/- 0.6 years. Overall, lower urinary tract symptoms (LUTS) (49%) was the most common presenting complaint, followed by spraying (24%), urethrocutaneous fistula (18%), recurrent urinary tract infections (UTIs) (15%), and chordee (14%). Comparison demonstrated that Group 2 patients were more likely to present with LUTS (55% vs 26%; P = .038) and recurrent UTIs (19% vs 0%; P = .050). There was a trend toward Group 1 patients presenting more commonly with cosmetic dissatisfaction (16% vs 4%; P = .06). Urethral stricture was demonstrated more commonly in Group 2 (47% vs 11%; P = .0043). Of these, strictures were significantly longer in the previous surgery group (5.5 +/- 0.6 cm vs 3.0 +/- 0.6 cm, P = .019). CONCLUSION: Correction of hypospadias as a child likely increases the future risk of urethral stricture, recurrent UTIs, and subsequent LUTS, with a trend toward improving patient satisfaction with cosmesis compared to nonsurgical management. Follow-up of hypospadias repair patients should extend into adulthood, as a significant portion of adult presentations ultimately require surgical intervention. PMID- 27693572 TI - Contemporary Trends in the Inpatient Management of Fournier's Gangrene: Predictors of Length of Stay and Mortality Based on Population-based Sample. AB - OBJECTIVE: To describe clinical management of Fournier's gangrene and to characterize predictive factors associated with inpatient mortality and extended hospital stay. MATERIALS AND METHODS: The National Inpatient Sample was queried from 2004 to 2012 based on the International Classification of Diseases, Ninth Revision, Clinical Modification procedural and diagnosis codes. Patients admitted for Fournier's gangrene who underwent debridement were selected. Multivariate logistic regression analysis was performed to identify predictors of inpatient mortality and extended hospital stay. RESULTS: A total of 9249 patients were identified for a weighted estimate of 43,146 cases. Inpatient mortality was 4.7%. The median length of stay was 9 days (interquartile range 5-17 days). The most common procedure in addition to debridement was a complex closure (8.82%), followed by suprapubic tube placement (5.70%) and fecal diversion (4.68%). Increasing age, yearly hospital volume >10 cases, and Medicaid insurance status were associated with increased risk of mortality. Increasing age, teaching hospital status, increasing number of comorbidities, and Medicaid as a payor were predictive of increased hospital stay. Suprapubic tube placement (odds ratio [OR] 2.8 [95% confidence interval {CI} 1.92-4.07], P <= .001), fecal diversion (OR 11.1 [95% CI 6.20-19.7], P <= .001), and complex wound closure (OR 4.89 [95% CI 3.97-6.89], P <= .001) were also predictive of increased length of stay. CONCLUSION: Identifiable patient and hospital characteristics are predictive of both mortality and length of stay in the management of Fournier's gangrene. Overall inpatient mortality appears lower than what has been reported in the majority of prior reports. The strongest predictor for increased length of stay is the need for complex wound closure, and urinary or fecal diversion.

PMID- 27693574 TI - Hybrid Transvaginal NOTES Nephrectomy: Postoperative Sexual Outcomes. A Three center Matched Study. AB - OBJECTIVE: To evaluate our experience in patients undergoing hybrid transvaginal natural orifices transluminal endoscopic surgery (NOTES) nephrectomy and evaluate the sexual functions in the postoperative period. MATERIALS AND METHODS: Prospective data of 71 patients with renal tumors who underwent hybrid NOTES radical nephrectomy in three different centers were collected from March 2010 to October 2015. Patient and surgical characteristics were recorded. Sexual function was evaluated using the Female Sexual Function Index questionnaire the day prior to the operation and 3 months after. RESULTS: The mean age, tumor size, and operation duration were 66.16 +/- 11.21, 8.51 +/- 3.31 cm, and 119.94 +/- 21.38 minutes, respectively. Five patients were immediately reoperated due to bleeding from uterine veins. The complication risk increases significantly with increasing tumor size. Among the whole cohort, even the Female Sexual Function Index score differences are small; there is a statistically significant decrease in the postoperative period in all domains except sexual satisfaction. In fact, the patients reported unaltered sexual function after surgery and satisfaction with the result when asked directly. In subgroup analyses, in nulliparous patients (n = 60), arousal, sexual desire, orgasm, and satisfaction domains have no significant differences in pre- and postoperative periods. CONCLUSIONS: Hybrid NOTES nephrectomy is a feasible, safe operation that can be performed for large renal tumors. Due to incisions in the vaginal wall for specimen retrieval, sexual function can be altered in the postoperative period. So patient selection, preoperative evaluation, and close follow-up are mandatory. With this in mind, we strongly support the use of hybrid transvaginal NOTES nephrectomy for large renal tumors especially in nulliparous patients. PMID- 27693576 TI - Immunochemical evaluation of two Toxoplasma gondii GRA8 sequences to detect acute toxoplasmosis infection. AB - In this work, two Toxoplasma gondii GRA8 protein sequences were tested by indirect ELISA and measurement of avidity to differentiate between acute and chronic toxoplasmosis infection. Using the antigen called GRA8B, 79.7% sensitivity and 84.1% specificity was achieved detecting IgG concentrations and a 71.2% sensitivity and a 68.3% specificity detecting IgA concentrations. This study is the first to report IgA detection with GRA8 by ELISA to differentiate stages of infection. Unfortunately the indirect ELISA to detect IgM was not effective in distinguishing stages. Also, this work is the first to report that the GRA8 protein can aid the differentiation between acute and chronic phase infection by measuring IgG antibody avidity, a technique in which we obtained 85.71% and 100% of sensitivity and specificity, respectively. Finally, in silico tools were used to explain the differences in our immunochemistry results. PMID- 27693575 TI - Stress reactivity and personality in extreme sport athletes: The psychobiology of BASE jumpers. AB - This is the first report of the psychobiology of stress in BASE jumpers, one of the most dangerous forms of extreme sport. We tested the hypotheses that indicators of emotional style (temperament) predict salivary cortisol reactivity, whereas indicators of intentional goal-setting (persistence and character) predict salivary alpha-amylase reactivity during BASE jumping. Ninety-eight subjects completed the Temperament and Character Inventory (TCI) the day before the jump, and 77 also gave salivary samples at baseline, pre-jump on the bridge over the New River Gorge, and post-jump upon landing. Overall BASE jumpers are highly resilient individuals who are highly self-directed, persistent, and risk taking, but they are heterogeneous in their motives and stress reactivity in the Hypothalamic-Pituitary-Adrenal (HPA) stress system (cortisol reactivity) and the sympathetic arousal system (alpha-amylase reactivity). Three classes of jumpers were identified using latent class analysis based on their personality profiles, prior jumping experience, and levels of cortisol and alpha-amylase at all three time points. "Masterful" jumpers (class 1) had a strong sense of self directedness and mastery, extensive prior experience, and had little alpha amylase reactivity and average cortisol reactivity. "Trustful" jumpers (class 2) were highly cooperative and trustful individuals who had little cortisol reactivity coincident with the social support they experienced prior to jumping. "Courageous" jumpers (class 3) were determined despite anxiety and inexperience, and they had high sympathetic reactivity but average cortisol activation. We conclude that trusting social attachment (Reward Dependence) and not jumping experience predicted low cortisol reactivity, whereas persistence (determination) and not jumping experience predicted high alpha-amylase reactivity. PMID- 27693577 TI - Antifungal activity of eicosanoic acids isolated from the endophytic fungus Mycosphaerella sp. against Cryptococcus neoformans and C. gattii. AB - The antifungal effects of two eicosanoic acids, 2-amino-3,4-dihydroxy-2-25 (hydroxymethyl)-14-oxo-6,12-eicosenoic acid (compound 1) and myriocin (compound 2), isolated from Mycosphaerella sp. were evaluated against Cryptococcus neoformans and C. gattii. The compounds displayed antifungal activities against several isolates of C. neoformans and C. gattii, with minimal inhibitory concentration (MIC) values ranging from 0.49 to 7.82 MUM for compound 1 and 0.48 1.95 MUM for compound 2. In the checkerboard microtiter test, both compounds exhibited synergistic activity with amphotericin B against C. gattii. Ultrastructural analysis revealed several signs of damage in C. gattii and C. neoformans cells treated with compounds 1 and 2, including deformities in cell shape, depressions on the surface, and withered cells. The cells of C. gattii treated with compounds 1 and 2 showed less loss of cellular material in comparison to those treated with amphotericin B. The difference in cellular material loss increased in a test compound concentration-dependent manner. Consistent with this observation, compounds 1 and 2 were able to internalize propidium iodide (PI) in C. gattii cells. In addition, compound 2 induced the formation of several pseudohyphae, suggesting that it could reduce virulence in C. gattii cells. The study results show that these natural products led to membrane damage; however, this may not be the main target of action. These compounds have potential antifungal activity and could be useful in further studies for developing more effective combination therapies with amphotericin B and reducing side effects in patients. PMID- 27693578 TI - The E3 ubiquitin ligase c-Cbl mediates integrin beta1 ubiquitination during dilated cardiomyopathy. AB - Dilated cardiomyopathy (DCM) is characterized by dilatation of the ventricular chambers and impaired myocardial contractility. The results of our previous study indicated that a deficiency in matricellular cartilage oligomeric matrix protein (COMP) led to spontaneous and progressive DCM in mice via the ubiquitination/degradation of integrin beta1. However, the specific ubiquitin enzyme involved in degradation of integrin beta1 and the pathogenesis of DCM remain elusive. We first compared gene expression profiles in hearts from 3-month old wild type and COMP-/- mice using microarray analysis. Among the E3 ubiquitin ligases upregulated in COMP-/- hearts, c-Cbl silencing rescued the ubiquitination/degradation of integrin beta1, myofilament loss, apoptosis and connexin-43 deficiency in cardiomyocytes due to the silencing of COMP. Furthermore, c-Cbl silencing by intramyocardial injections of siRNA into 1-month old COMP-/- mice ameliorated spontaneous DCM in vivo, as evidenced by the inhibition of the dilation of ventricular chambers, impaired ejection fraction and myofilament loss. A subsequent cellular ubiquitination assay revealed that overexpression of c-Cbl induced ubiquitination of integrin beta1, whereas the G306E mutation in c-Cbl, which prevented the binding of c-Cbl to its substrates, had no effect on integrin beta1 ubiquitination, indicating that c-Cbl directly caused the ubiquitination of integrin beta1 in the hearts. In conclusion, our results demonstrate that c-Cbl mediates the ubiquitination/degradation of integrin beta1, which leads to COMP deficiency-induced DCM. PMID- 27693579 TI - The oxoglutarate receptor 1 (OXGR1) modulates pressure overload-induced cardiac hypertrophy in mice. AB - The G-protein-coupled receptors (GPCRs) family of proteins play essential roles in the heart, including in the regulation of cardiac hypertrophy. One member of this family, the oxoglutarate receptor 1 (OXGR1), may have a crucial role in the heart because it acts as a receptor for alpha-ketoglutarate, a metabolite that is elevated in heart failure patients. OXGR1 is expressed in the heart but its precise function during cardiac pathophysiological process is unknown. Here we used both in vivo and in vitro approaches to investigate the role of OXGR1 in cardiac hypertrophy. Genetic ablation of Oxgr1 in mice (OXGR1-/-) resulted in a significant increase in hypertrophy following transverse aortic constriction (TAC). This was accompanied by reduction in contractile function as indicated by cardiac fractional shortening and ejection fraction. Conversely, adenoviral mediated overexpression of OXGR1 in neonatal rat cardiomyocytes significantly reduced phenylephrine-induced cardiomyocyte hypertrophy, a result that was consistent with the in vivo data. Using a combination of yeast two hybrid screening and phospho-antibody array analysis we identified novel interacting partner and downstream signalling pathway that might be regulated by the OXGR1. First, we found that OXGR1 forms a molecular complex with the COP9 signalosome complex subunit 5 (CSN5). Secondly, we observed that the STAT3 signalling pathway was upregulated in OXGR1-/- hearts. Since CSN5 interacts with TYK2, a major upstream regulator of STAT3, OXGR1 might regulate the pro-hypertrophic STAT3 pathway via interaction with the CSN5-TYK2 complex. In conclusion, our study has identified OXGR1 as a novel regulator of pathological hypertrophy via the regulation of the STAT3. Identification of molecules that can specifically activate or inhibit this receptor may be very useful in the development of novel therapeutic approach for pathological cardiac hypertrophy. PMID- 27693580 TI - Activin pathway enhances colorectal cancer stem cell self-renew and tumor progression. AB - Activin belongs to transforming growth factor (TGF)-beta super family of growth and differentiation factors and activin pathway participated in broad range of cell process. Studies elaborated activin pathway maintain pluripotency in human stem cells and suggest that the function of activin/nodal signaling in self-renew would be conserved across embryonic and adult stem cells. In this study, we tried to determine the effect of activin signaling pathway in regulation of cancer stem cells as a potential target for cancer therapy in clinical trials. A population of colorectal cancer cells was selected by the treatment of activin A. This population of cell possessed stem cell character with sphere formation ability. We demonstrated activin pathway enhanced the colorectal cancer stem cells self renew and contribute to colorectal cancer progression in vivo. Targeting activin pathway potentially provide effective strategy for colorectal cancer therapy. PMID- 27693581 TI - Fasting boosts sensitivity of human skin melanoma to cisplatin-induced cell death. AB - Melanoma is one of leading cause of tumor death worldwide. Anti-cancer strategy includes combination of different chemo-therapeutic agents as well as radiation; however these treatments have limited efficacy and induce significant toxic effects on healthy cells. One of most promising novel therapeutic approach to cancer therapy is the combination of anti-cancer drugs with calorie restriction. Here we investigated the effect Cisplatin (CDDP), one of the most potent chemotherapeutic agent used to treat tumors, in association with fasting in wild type and mutated BRAFV600E melanoma cell lines. Here we show that nutrient deprivation can consistently enhance the sensitivity of tumor cells to cell death induction by CDDP, also of those malignancies particularly resistant to any treatment, such as oncogenic BRAF melanomas. Mechanistic studies revealed that the combined therapy induced cell death is characterized by ROS accumulation and ATF4 in the absence of ER-stress. In addition, we show that autophagy is not involved in the enhanced sensitivity of melanoma cells to combined CDDP/EBSS induced apoptosis. While, the exposure to 2-DG further enhanced the apoptotic rate observed in SK Mel 28 cells upon treatment with both CDDP and EBSS. PMID- 27693582 TI - Proteasome inhibitor MG132 impairs autophagic flux through compromising formation of autophagosomes in Bombyx cells. AB - MG132 has been used as a proteasome inhibitor on Bombyx cells, but its physiological effects on autophagy still have not been elucidated. In this study, we find that the lipidated BmAtg8, BmAtg8-PE as an autophagosomal marker protein, is only localized to membranes. Then we established systems to monitor autophagic flux in Bombyx cells: Induction of autophagy reduces exogenous BmAtg8 and exogenous BmAtg8-PE, facilitates formation of autophagosomes indicated by green EGFP-BmAtg8 puncta after cotreatment by Rapamycin and Bafilomycin A1, and causes accumulation of free EGFP from EGFP-BmAtg8 cleavage in autolysosomes. Using these established systems, we find that exposure of MG132 inhibits both basal and Rapamycin-induced autophagy when polyubiquitinated proteins are accumulated markedly in Bombyx cells. Interestingly, we reveal that attenuation of autophagy in these cells is ascribed as distinct suppression of formation of autophagosomes after MG132 treatment. PMID- 27693583 TI - vIRF3 encoded by Kaposi's sarcoma-associated herpesvirus inhibits T-cell factor dependent transcription via a CREB-binding protein-interaction motif. AB - Kaposi's sarcoma-associated herpesvirus (KSHV) is an etiological agent of Kaposi's sarcoma and primary effusion lymphoma. Like other herpesviruses, KSHV has two distinct life cycles: latent and lytic. Among KSHV latent genes, viral interferon regulatory factor 3 (vIRF3), which shares homology with cellular IRFs, is a multifunctional protein. To identify unknown functions of vIRF3, we performed luciferase-reporter assays in the presence of vIRF3. These analyses revealed that overexpression of vIRF3 inhibited T-cell factor (TCF)-dependent transcriptional activity. This TCF-dependent transcription was associated with the Wnt signaling pathway, which normally regulates embryonic development, but contributes to oncogenesis under dysregulated conditions. Using a mutagenesis analysis, we identified a CREB-binding protein-interaction motif (LXXLL) in vIRF3 as an important region for its inhibitory activity. Collectively, our findings provide insight into the dysregulation of host signaling pathways in KSHV infected cells. PMID- 27693584 TI - Drug induced exocytosis of glycogen in Pompe disease. AB - Pompe disease is caused by a deficiency in the lysosomal enzyme alpha glucosidase, and this leads to glycogen accumulation in the autolysosomes of patient cells. Glycogen storage material is exocytosed at a basal rate in cultured Pompe cells, with one study showing up to 80% is released under specific culture conditions. Critically, exocytosis induction may reduce glycogen storage in Pompe patients, providing the basis for a therapeutic strategy whereby stored glycogen is redirected to an extracellular location and subsequently degraded by circulating amylases. The focus of the current study was to identify compounds capable of inducing rapid glycogen exocytosis in cultured Pompe cells. Here, calcimycin, lysophosphatidylcholine and alpha-l-iduronidase each significantly increased glycogen exocytosis compared to vehicle-treated controls. The most effective compound, calcimycin, induced exocytosis through a Ca2+-dependent mechanism, although was unable to release a pool of vesicular glycogen larger than the calcimycin-induced exocytic pore. There was reduced glycogen release from Pompe compared to unaffected cells, primarily due to increased granule size in Pompe cells. Drug induced exocytosis therefore shows promise as a therapeutic approach for Pompe patients but strategies are required to enhance the release of large molecular weight glycogen granules. PMID- 27693585 TI - Cleavage of influenza RNA by using a human PUF-based artificial RNA-binding protein-staphylococcal nuclease hybrid. AB - Various viruses infect animals and humans and cause a variety of diseases, including cancer. However, effective methodologies to prevent virus infection have not yet been established. Therefore, development of technologies to inactivate viruses is highly desired. We have already demonstrated that cleavage of a DNA virus genome was effective to prevent its replication. Here, we expanded this methodology to RNA viruses. In the present study, we used staphylococcal nuclease (SNase) instead of the PIN domain (PilT N-terminus) of human SMG6 as an RNA-cleavage domain and fused the SNase to a human Pumilio/fem-3 binding factor (PUF)-based artificial RNA-binding protein to construct an artificial RNA restriction enzyme with enhanced RNA-cleavage rates for influenzavirus. The resulting SNase-fusion nuclease cleaved influenza RNA at rates 120-fold greater than the corresponding PIN-fusion nuclease. The cleaving ability of the PIN fusion nuclease was not improved even though the linker moiety between the PUF and RNA-cleavage domain was changed. Gel shift assays revealed that the RNA binding properties of the PUF derivative used was not as good as wild type PUF. Improvement of the binding properties or the design method will allow the SNase fusion nuclease to cleave an RNA target in mammalian animal cells and/or organisms. PMID- 27693586 TI - Serum level of scorpion toxins, electrolytes and electrocardiogram alterations in Mexican children envenomed by scorpion sting. AB - The scorpion Centruroides limpidus limpidus (C.l.l.) is endemic in Mexico, producing hundreds of accidents in humans; children being one of the most susceptible targets. Few studies reported that severe envenoming by scorpion venom induces cardiac damage and electrolytes abnormalities in children, but the relationship of envenoming severity and toxic blood levels is unknown. The aim of this study was to determine the relationship among clinical status of envenoming, serum electrolyte, electrocardiographic abnormalities, and serum toxin levels in 44 children stung by scorpion over a period of 6 months in the State of Morelos, Mexico. The patients were said to be asymptomatic, when they presented just local symptoms, and were said to be symptomatic when showing local symptoms and at least one systemic symptom. The clinical status was evaluated at the admission at the emergency room of the Hospital, and 30 min after the administration of polyspecific F(ab')2 anti-scorpion therapy to symptomatic children. Forty-one percent of the children were asymptomatic and 59% symptomatic. Potassium and sodium imbalance and an elongation of the QT interval were detected; the rate of hypokalemia was higher in symptomatic than on asymptomatic children (50% and 6%, respectively). Hypokalemia persisted in 19% in symptomatic patients, whereas sodium reached normal levels 30 min after anti-venom therapy. The hypokalemia statistically correlated with elongation of the QT interval. The concentration of the toxic components of C.l.l in serum was significantly higher in symptomatic than asymptomatic children, and the serum levels of the toxic component significantly decreased to undetectable levels after the application of anti venom therapy. Despite the small size of the sample, this study establishes that severity of envenoming was statistically related to potassium imbalance in serum, QT interval and the concentration of toxic components in serum, which decreased at undetectable levels after specific treatment with the anti-scorpion venom, correlating with clinical disappearance or greatly reduction of symptoms of envenomation. PMID- 27693587 TI - Attention-deficit/hyperactivity disorder and eating disorders across the lifespan: A systematic review of the literature. AB - Attention-deficit/hyperactivity disorder (ADHD) and eating disorders are common and concerning mental health disorders. There is both empirical and theoretical support for an association between ADHD and eating disorders or disordered eating. This systematic review aims to summarize the extant literature on the comorbidity of ADHD and eating disorders across the lifespan, including the influences of sex, age, eating disorder diagnosis, and potential mediators. A total of 37 peer-reviewed studies on diagnosed ADHD and eating disturbances were identified through key research databases. Twenty-six studies supported a strong empirical association between ADHD and eating disorders or disordered eating. The systematic review findings suggest that children with ADHD are at risk for disordered eating, while adolescents, emerging adults, and adults are at risk for both eating disorders and disordered eating. Methodological considerations, future research, and clinical implications are discussed. PMID- 27693588 TI - Genetics of human lupus nephritis. AB - Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease characterized by immune complex formation with multi-organ manifestations. Lupus nephritis (LN) is one of the most severe types of organ damage in SLE, and it clearly contributes to increased morbidity and mortality due to SLE. LN occurs more frequently and is more severe in non-European ancestral backgrounds, although the cause of this disparity remains largely unknown. Genetic factors play an important role in the pathogenesis of SLE. Although many SLE susceptibility genes have been identified, the genetic basis of LN is not as well understood. While some of the established general SLE susceptibility genes are associated with LN, recent discoveries highlight a number of genes with renal functions that are specifically associated with LN. Some of these genes associated with LN help to explain the disparity in the prevalence of nephritis between individuals with SLE, and also partially explain differences in LN between ancestral backgrounds. Moreover, not only the gene mutations, but also post-translational modifications seem to play important roles in the pathogenesis of LN. Overall it seems likely that a combination of general SLE susceptibility genes cooperate with LN specific risk genes to result in the genetic propensity for LN. In this review, we will outline the genetic contribution to LN and describe possible roles of LN susceptibility genes. PMID- 27693589 TI - Probing phosphoethanolamine-containing lipids in membranes with duramycin/cinnamycin and aegerolysin proteins. AB - In this mini-review, we summarize current knowledge about the lipid-binding characteristics of two types of toxins used to visualize the membrane distribution of phosphoethanolamine-containing lipid species: the glycerophospholipid, phosphatidylethanolamine (PE) and the sphingolipid, ceramide phosphoethanolamine (CPE). The lantibiotic cinnamycin and the structurally related peptide duramycin produced by some Gram-positive bacteria were among the first toxins characterized by their specificity for PE which is widely present in animal kingdoms from bacteria to mammals. These toxins promoted their binding to PE-containing membranes by changing membrane curvature and by inducing transbilayer lipid movement. The recognition of the conical shape and negative curvature adopted by the PE species within the membrane, is important to understand how lipid-peptide interaction can occur. Three mushroom-derived proteins belonging to the aegerolysin family, pleurotolysin A2, ostreolysin and erylysin A were recently described as efficient tools to visualize the membrane distribution of CPE which is found in trace amounts in mammalian cells but in higher amounts in some developmental stages of lower eukaryotes like Trypanosoma and in invertebrates such as Drosophila. The recent development of lantibiotic based PE-specific and aegerolysin-based CPE-specific probes is useful to visualize and specify the role of these lipids in various pathophysiological events such as cell division, apoptosis, tumor vasculature and parasite developmental stages. PMID- 27693590 TI - Food as a supplementary cue triggers seasonal changes in aggression, but not reproduction, in Siberian hamsters. AB - Animals living in temperate regions prepare for harsh winter conditions by responding to environmental cues that signal resource availability (e.g., food, day length). Siberian hamsters (Phodopus sungorus) breed in long, summer-like days (LD, >14h light), i.e., photoperiods, and undergo robust gonadal regression and become more aggressive when exposed to short, winter-like photoperiods that signal impending limited resources (SD, <10h light). When hamsters are reared within an intermediate photoperiod (ID, 13.5h light), they are reproductively active, but undergo gonadal regression in response to mild food restriction (FR) over 6-12weeks. We hypothesized that short-term (1-2weeks) FR in an ID photoperiod would provide a signal of impending limited resources and initiate the seasonal increase in aggression typical of SD photoperiods, as well as alter reproductive behaviors in advance of gonadal regression. To test this, we housed male and female hamsters in LD or ID photoperiods, with ad libitum (AL) access to food or a 90%-AL ration. We tested aggressive behavior after one week and reproductive behavior after two weeks, and subsequently monitored females for pregnancy and litter production. Both sexes displayed increased aggression in the ID-FR treatment. Untreated male intruders were less likely to ejaculate when paired with ID females during reproductive encounters. ID-FR males were undergoing gonadal regression after two weeks, but were more likely to have ejaculated. Female pregnancy and litter characteristics were unaltered by treatment: females were equally likely to achieve pregnancy and produce comparable litters across treatment groups. Collectively, we demonstrate that a signal of diminishing resources in an ID photoperiod is sufficient to trigger seasonal aggression, but that hamsters are reproductively resilient to inhibitory environmental cues in the short term. Broadly, our findings provide an important context for exploring seasonal changes in behavior and physiology from an ultimate perspective.

PMID- 27693591 TI - Ovariectomy results in inbred strain-specific increases in anxiety-like behavior in mice. AB - Women are at an increased risk for developing affective disorders during times of hormonal flux, including menopause when the ovaries cease production of estrogen. However, while all women undergo menopause, not all develop an affective disorder. Increased vulnerability can result from genetic predisposition, environmental factors and gene by environment interactions. In order to investigate interactions between genetic background and estrogen depletion, we performed bilateral ovariectomy, a surgical procedure that results in estrogen depletion and is thought to model the post-menopausal state, in a genetically defined panel of 37 inbred mouse strains. Seventeen days post-ovariectomy, we assessed behavior in two standard rodent assays of anxiety- and depressive-like behavior, the open field and forced swim tests. We detected a significant interaction between ovariectomy and genetic background on anxiety-like behavior in the open field. No strain specific effects of ovariectomy were observed in the forced swim assay. However, we did observe significant strain effects for all behaviors in both the open field and forced swim tests. This study is the largest to date to look at the effects of ovariectomy on behavior and provides evidence that ovariectomy interacts with genetic background to alter anxiety-like behavior in an animal model of menopause. PMID- 27693593 TI - The contribution of trait negative affect and stress to recall for bodily states. AB - How does trait negative affect shape somatic memory of stressful events? We hypothesized that negative affect would impair accurate recall of one's own heart rate during stressful situations. Two bio-behavioral studies used a new paradigm to test retrospective visceral perception and assessed whether negative affective states experienced during aversive events (i.e., the Trier Stress Task-Time 1) would retrospectively shape recall of past heart rate (Time 2), even when accounting for actual heart rate at the time of each stressful event (Time 1). Results across both studies showed that individual differences in negative affect in response to a stressful task predicted visceral recollections, and those who experienced more negative affect were more inaccurate. Negative affect was associated with a tendency to remember visceral reactions as worse than they actually were. PMID- 27693595 TI - Biomarker Development in COPD: Moving From P Values to Products to Impact Patient Care. AB - There is a great interest in developing biomarkers to enable precision medicine and improve health outcomes of patients with COPD. However, biomarker development is extremely challenging and expensive, and translation of research endeavors to date has been largely unsuccessful. In most cases, biomarkers fail because of poor replication of initial promising results in independent cohorts and/or inability to transfer the biomarker from a discovery platform to a clinical assay. Ultimately, new biomarker assays must address 5 questions for optimal clinical translation. They include the following: is the biomarker likely to be (1) superior (will the test outperform current standards?); (2) actionable (will the test change patient management?); (3) valuable (will the test improve patient outcomes?); (4) economical (will the implementation of the biomarker in the target population be cost-saving or cost-effective?); and (5) clinically deployable (is there a pathway for the biomarker and analytical technology to be implemented in a clinical laboratory?)? In this article we review some of the major barriers to biomarker development in COPD and provide possible solutions to overcome these limitations, enabling translation of promising biomarkers from discovery experiments to clinical implementation. PMID- 27693596 TI - Variation of Ciliary Beat Pattern in Three Different Beating Planes in Healthy Subjects. AB - BACKGROUND: Digital high-speed video microscopy (DHSV) allows analysis of ciliary beat frequency (CBF) and ciliary beat pattern (CBP) of respiratory cilia in three planes. Normal reference data use a sideways edge to evaluate ciliary dyskinesia and calculate CBF using the time needed for a cilium to complete 10 beat cycles. Variability in CBF within the respiratory epithelium has been described, but data concerning variation of CBP is limited in healthy epithelium. This study aimed to document variability of CBP in normal samples, to compare ciliary function in three profiles, and to compare CBF calculated over five or 10 beat cycles. METHODS: Nasal brushing samples from 13 healthy subjects were recorded using DHSV in three profiles. CBP and CBF over a 10-beat cycle were evaluated in all profiles, and CBF was reevaluated over five-beat cycles in the sideways edges. RESULTS: A uniform CBP was seen in 82.1% of edges. In the sideways profile, uniformity within the edge was lower (uniform normal CBP, 69.1% [sideways profile]; 97.1% [toward the observer], 92.0% [from above]), and dyskinesia was higher. Interobserver agreement for dyskinesia was poor. CBF was not different between profiles (P = .8097) or between 10 and five beat cycles (P = .1126). CONCLUSIONS: Our study demonstrates a lack of uniformity and consistency in manual CBP analysis of samples from healthy subjects, emphasizing the risk of automated CBP analysis in limited regions of interest and of single and limited manual CBP analysis. The toward the observer and from above profiles may be used to calculate CBF but may be less sensitive for evaluation of ciliary dyskinesia and CBP. CBF can be measured reliably by evaluation of only five-beat cycles. PMID- 27693594 TI - OSA and Cardiac Arrhythmogenesis: Mechanistic Insights. AB - A surge of data has reproducibly identified strong associations of OSA with cardiac arrhythmias. As an extension of epidemiologic and clinic-based findings, experimental investigations have made strides in advancing our understanding of the putative OSA and cardiac arrhythmogenesis mechanistic underpinnings. Although most studies have focused on the links between OSA and atrial fibrillation (AF), relationships with ventricular arrhythmias have also been characterized. Key findings implicate OSA-related autonomic nervous system fluctuations typified by enhanced parasympathetic activation during respiratory events and sympathetic surges subsequent to respiratory events, which contribute to augmented arrhythmic propensity. Other more immediate pathophysiologic influences of OSA-enhancing arrhythmogenesis include intermittent hypoxia, intrathoracic pressure swings leading to atrial stretch, and hypercapnia. Intermediate pathways by which OSA may trigger arrhythmia include increased systemic inflammation, oxidative stress, enhanced prothrombotic state, and vascular dysfunction. Long-term OSA-associated sequelae such as hypertension, atrial enlargement and fibrosis, ventricular hypertrophy, and coronary artery disease also predispose to cardiac arrhythmia. These factors can lead to a reduction in atrial effective refractory period, triggered and abnormal automaticity, and promote slowed and heterogeneous conduction; all of these mechanisms increase the persistence of reentrant arrhythmias and prolong the QT interval. Cardiac electrical and structural remodeling observed in OSA animal models can progress the arrhythmogenic substrate to further enhance arrhythmia generation. Future investigations clarifying the contribution of specific OSA-related mechanistic pathways to arrhythmia generation may allow targeted preventative therapies to mitigate OSA induced arrhythmogenicity. Furthermore, interventional studies are needed to clarify the impact of OSA pathophysiology reversal on cardiac arrhythmogenesis and related adverse outcomes. PMID- 27693597 TI - A Subnational Analysis of Mortality and Prevalence of COPD in China From 1990 to 2013: Findings From the Global Burden of Disease Study 2013. AB - BACKGROUND: The trends of COPD mortality and prevalence over the past 2 decades across all provinces remain unknown in China. We used data from the Global Burden of Disease Study 2013 (GBD 2013) to estimate the mortality and prevalence of COPD during 1990 to 2013 at a provincial level. METHODS: Following the general analytic strategy used in GBD 2013, we analyzed the age- sex- and province specific mortality and prevalence of COPD in China. Levels of and trends in COPD mortality and prevalence were assessed for 33 province-level administrative units during 1990 to 2013. RESULTS: In 2013, there were 910,809 deaths from COPD in China, accounting for 31.1% of the total deaths from COPD in the world. From 1990 to 2013, the age-standardized COPD mortality rate decreased in all provinces, with the highest reduction in Heilongjiang (70.2%) and Jilin (70.0%) and the lowest reduction in Guizhou (26.8%). In 2013, the death rate per 100,000 was highest in Guizhou (196.0) and lowest in Tianjin (34.0) among men and highest in Gansu (141.1) and lowest in Beijing (23.7) among women. The number of COPD cases increased dramatically from 32.4 million in 1990 to 54.8 million in 2013. The age standardized prevalence rate of COPD remained stable overall and varied little for all provinces. CONCLUSIONS: COPD remains a huge health burden in many western provinces in China. The substantial increase in COPD cases represents an ongoing challenge given the rapidly aging Chinese population. A targeted control and prevention strategy should be developed at a provincial level to reduce the burden caused by COPD. PMID- 27693598 TI - Impact of cerium oxide nanoparticles shape on their in vitro cellular toxicity. AB - Cerium oxides (CeO2) nanoparticles, also referred to as nanoceria, are extensively used with a wide range of applications. However, their impact on human health and on the environment is not fully elucidated. The aim of this study was to investigate the influence of the CeO2 nanoparticles morphology on their in vitro toxicity. CeO2 nanoparticles of similar chemical composition and crystallinity were synthesized, only the shape varied (rods or octahedrons/cubes). Macrophages from the RAW264.7 cell line were exposed to these different samples and the toxicity was evaluated in terms of lactate dehydrogenase (LDH) release, Tumor Necrosis Factor alpha (TNF-alpha) production and reactive oxygen species (ROS) generation. Results showed no ROS production, whatever the nanoparticle shape. The LDH release and the TNF-alpha production were significantly and dose-dependently enhanced by rod-like nanoparticles, whereas they did not vary with cubic/octahedral nanoparticles. In conclusion, a strong impact of CeO2 nanoparticle morphology on their in vitro toxicity was clearly demonstrated, underscoring that nanoceria shape should be carefully taken in consideration, especially in a "safer by design" context. PMID- 27693599 TI - Pleiotropic properties of ASK1. AB - BACKGROUND: Apoptosis signal-regulating kinase 1 (ASK1), also known as mitogen activated protein kinase kinase kinase 5 (MAP3K5), has the potential to induce cellular apoptosis under various physiological conditions. It has long been suggested that ASK1 is highly sensitive to oxidative stress and contributes substantially to apoptosis. However, recent studies have indicated that ASK1 has pleiotropic roles in living organisms through other mechanisms in addition to apoptosis. SCOPE OF THE REVIEW: This review describes the physiological functions of ASK1 in living organisms, focusing on the regulatory mechanisms of ASK1 activity and its importance in the pathogenesis of various diseases. We also highlight recent works published within the past few years. MAJOR CONCLUSIONS: ASK1 forms a high-molecular-mass complex within the cell, designated as the ASK1 signalosome. Soon after the discovery of ASK1, several regulatory components of the ASK1 signalosome have been revealed, including thioredoxin (Trx), tumor necrosis factor alpha receptor-associated factors (TRAFs) and 14-3-3s. In parallel with the precise analyses unveiling the molecular basis of ASK1 regulation, the physiological or pathophysiological significance of ASK1 in diverse organs has been elucidated. In addition to the generation of global knockout mice or tissue-specific knockout mice, ASK1-specific inhibitors have illuminated the biological roles of ASK1. GENERAL SIGNIFICANCE: The multi-faceted features of the function of ASK1 have been discovered over the past two decades, revealing that ASK1 is a crucial molecule for maintaining cellular homeostasis, especially under conditions of stress. Based on the results that ASK1 deficiency provides beneficial effects for several diseases, modulating ASK1 activity is a promising method to ameliorate a subset of diseases. PMID- 27693600 TI - Nonlinear coda wave interferometry for the global evaluation of damage levels in complex solids. AB - A nonlinear acoustic method to assess the damage level of a complex medium is discussed herein. Thanks to the highly nonlinear elastic signatures of cracks or, more generally, internal solid contacts, this method is able to distinguish between contributions from linear wave scattering by a heterogeneity and contributions from nonlinear scattering by a crack or unbounded interface. The coda wave interferometry (CWI) technique is applied to reverberated and scattered waves in glass plate samples featuring various levels of damage. The ultrasonic coda signals are recorded in both the absence and presence of an independent and lower-frequency elastic "pump" wave, before being analyzed by CWI. The monitored CWI parameters quantifying changes in these coda signals, which therefore quantify the nonlinear wave-mixing effects between the coda and pump waves, are found to be dependent on the damage level in the sample. A parametric study is also performed to analyze the influence of sensor positions and average temperature on the method's output. The reported results could be applied to the non-destructive testing and evaluation of complex-shape materials and multiple scattering samples, for which conventional ultrasonic methods show strong limitations. PMID- 27693601 TI - Lung surfactant: Function and composition in the context of development and respiratory physiology. AB - Lung surfactant is a complex with a unique phospholipid and protein composition. Its specific function is to reduce surface tension at the pulmonary air-liquid interface. The underlying Young-Laplace equation, applying to the surface of any geometrical structure, is the more important the smaller its radii are. It therefore applies to the alveoli and bronchioli of mature lungs, as well as to the tubules and saccules of immature lungs. Surfactant comprises 80% phosphatidylcholine (PC), of which dipalmitoyl-PC, palmitoyl-myristoyl-PC and palmitoyl-palmitoleoyl-PC together are 75%. Anionic phosphatidylglycerol and cholesterol are about 10% each, whereas surfactant proteins SP-A to -D comprise 2 5%. Maturation of the surfactant system is not essentially due to increased synthesis but to decreased turnover of specific components. Molecular differences correlate with resting respiratory rate (RR), where PC16:0/16:0 is the lower the higher RR is. PC16:0/14:0 is increased during alveolar formation, and decreases immune reactions that might impair alveolar development. In rigid bird lungs, with air-capillaries rather than alveoli, and no surface area changes during the respiratory cycle, PC16:0/16:0 is highest and PC16:0/14:0 absent. As there is no need for a surface-associated surfactant reservoir, SP-C is absent in birds as well. Airflow is lowest and particle sedimentation highest in the extrapulmonary air-sacs, rather than in the gas-exchange area. Consequently, SP-A and -D for particle opsonization are absent in bird surfactant. In essence, comparative analysis is consistent with the concept that surfactant is adapted to the physiologic needs of a given vertebrate species at a given developmental stage. PMID- 27693602 TI - Fetal development of the pulley for muscle insertion tendons: A review and new findings related to the tensor tympani tendon. AB - The existence of hard tissue pulleys that act to change the direction of a muscle insertion tendon is well known in the human body. These include (1) the trochlea for the extraocular obliquus superior muscle, (2) the pterygoid hamulus for the tensor veli palatini muscle, (3) the deep sulcus on the plantar aspect of the cuboid bone for the peroneus longus tendon, (4) the lesser sciatic notch for the obturator internus muscle, and (5) the bony trochleariformis process for the tensor tympani muscle tendon. In addition, (6) the stapedius muscle tendon shows a lesser or greater angulation at the pyramidal eminence of the temporal bone. Our recent studies have shown that the development of pulleys Nos. 1 and 2 can be explained by a change in the topographical relationship between the pulley and the tendon, that of pulley No. 3 by the rapidly growing calcaneus pushing the tendon, and that of pulley No. 4 by migration of the insertion along the sciatic nerve and gluteus medius tendon. Therefore, in Nos. 1-4, an initially direct tendon curves secondarily and obtains an attachment to the pulley. In case No. 6, the terminal part of the stapedius tendon originates secondarily from the interzone mesenchymal tissue of the incudostapedial joint. In the case of pulley No. 5, we newly demonstrated that its initial phase of development was similar to No. 6, but the tensor tympani tendon achieved a right-angled turn under guidance by a specific fibrous tissue and it migrated along the growing malleus manubrium. PMID- 27693603 TI - Analysis of amino acids in human blood using UHPLC-MS/MS: Potential interferences of storage time and vacutainer tube in pre-analytical procedure. AB - OBJECTIVES: To investigate potential interferences of two pre-analytical variables, the storage time and the vacutainer tube, on the quantification of 20 amino acids using a UHPLC-MS/MS method. DESIGN AND METHODS: Blood samples from 25 apparently healthy subjects were collected into duplicate sets of EDTA-2K, EDTA 3K, coagulation, heparin and citrate tubes, and stored in capped vacutainer tubes at 4 degrees C for 6h, 12h and 24h before sample analysis. A UHPLC-MS/MS method was established for simultaneous quantification of 20 amino acids. ANOVA for repeated measurement was conducted based on the model of Mauchly's test of Sphericity. Student's t-test was applied for comparison between amino acid concentrations obtained from different vacutainer tubes, and consistency of the results was checked through Bland-Altman difference plots and Passing-Bablok regression analysis. RESULTS: Most of the 20 amino acids showed a least concentration fluctuation with storage time in heparin plasma, followed by EDTA 3K and citrate plasma. The amino acid concentrations were significantly lower in citrate plasma and slightly higher in serum, compared with those in heparin plasma. No fixed bias was observed for amino acid concentrations in EDTA and heparin plasma, but the differences were mostly of statistical significance. Amino acid concentrations in EDTA-3K plasma achieved a good consistency with those in heparin plasma by UHPLC-MS/MS analysis. CONCLUSIONS: Storage time and vacutainer tube were important variables for amino acid analysis. They should draw researchers' attention and then be controlled in good laboratory practice to reduce pre-analytical errors. PMID- 27693604 TI - Anaerobic digestion of straw and corn stover: The effect of biological process optimization and pre-treatment on total bio-methane yield and energy performance. AB - Anaerobic digestion (AD) is a useful method for producing renewable energy/biofuel. Today, biogas production uses a large amount of energy crops (EC), with the effect of increasing AD costs and creating conflict between food/feed vs. energy use. A partial solution to this might be the substitution of EC with agricultural wastes, e.g. straw. Straw and corn stover are widely available in the world and approximately 1600millionMgyear-1 of these substrates are available. Straw can be useful used for biogas production but its characteristics limit its performance so that sometimes the energetic balance can be negative. In this review, the limits for the conversion of this substrate into biogas were investigated and solutions/proposals for getting higher straw biogas production performance are reported. In addition, energetic balances for untreated and pre-treated substrates are reported, giving indicative evaluations of the sustainability of straw and corn stover use for biogas production. PMID- 27693605 TI - The Prognostic Significance of Different Definitions for Angiosome-Targeted Lower Limb Revascularization. AB - BACKGROUND: The definition of angiosome-targeted revascularization is confusing, especially when a tissue lesion affects several angiosomes. Two different definitions of direct revascularization exist in the literature. The study aim was (1) to compare the 2 definitions of direct revascularization in patients with foot lesions involving more than one angiosome and (2) to evaluate which definition better predicts clinical outcome. METHODS: This study cohort comprises 658 patients with Rutherford 5-6 foot lesions who underwent infrapopliteal endovascular or surgical revascularization between January 2010 and July 2013. We compared the 2 angiosome-targeted definitions using multivariate analysis; the impact of each angiosome-targeted definition was adjusted for a propensity score obtained by means of nonparsimonious logistic regression. RESULTS: Direct revascularization according to definition A was performed in 367 cases (55.8%) versus 198 cases (30.1%) with definition B. The propensity-score-adjusted analysis showed that definition A of direct revascularization was associated with significantly better wound healing (P < 0.044, hazard ratio [HR] 1.291) and lower amputation rates (P < 0.047, HR 0.706), whereas definition B was associated only with significantly better wound healing (P < 0.029, HR 1.321). The prognostic ability of direct revascularization according to definition A was confirmed in a Cox proportional hazard analysis. CONCLUSIONS: Definition A of direct revascularization was associated with a significantly higher wound healing and leg salvage rate than indirect revascularization in both series. Therefore, it seems that, if the wound spreads over several angiosomes in the forefoot or heel, any angiosome involved in the wound can be targeted. PMID- 27693606 TI - Technical aspects of MRI signal change quantification after gadolinium-based contrast agents' administration. AB - Over the last 2years several studies have been published regarding gadolinium deposition in brain structures in patients with normal renal function after repeated administrations of gadolinium-based contrast agents (GBCAs). Most of the publications are magnetic resonance imaging (MRI) based retrospective studies, where gadolinium deposition may be indirectly measured by evaluating changes in T1 signal intensity (SI) in brain tissue, particularly in the dentate nucleus (DN) and/or globus pallidi (GP). The direct correlation between T1 signal changes and gadolinium deposition was validated by human pathology studies. However, the variability of the MR equipment and parameters used across different publications, along with the inherent limitations of MRI to assess gadolinium in human tissues should be acknowledged when interpreting those studies. Nevertheless, MRI studies remain essential regarding gadolinium bio-distribution knowledge. The aim of this paper is to overview current knowledge of technical aspects of T1 signal intensity evaluation by MRI and describe confounding factors, with the intention to achieve higher accuracy and maximize reproducibility. PMID- 27693607 TI - Gadolinium toxicity and treatment. AB - Gadolinium based contrast agents (GBCAs) play an important role in the diagnostic evaluation of many patients. The safety of these agents has been once again questioned after gadolinium deposits were observed and measured in brain and bone of patients with normal renal function. This retention of gadolinium in the human body has been termed "gadolinium storage condition". The long-term and cumulative effects of retained gadolinium in the brain and elsewhere are not as yet understood. Recently, patients who report that they suffer from chronic symptoms secondary to gadolinium exposure and retention created gadolinium-toxicity on line support groups. Their self-reported symptoms have recently been published. Bone and joint complaints, and skin changes were two of the most common complaints. This condition has been termed "gadolinium deposition disease". In this review we will address gadolinium toxicity disorders, from acute adverse reactions to GBCAs to gadolinium deposition disease, with special emphasis on the latter, as it is the most recently described and least known. PMID- 27693609 TI - Neural oscillations as a bridge between glutamatergic system and emotional behaviors in simulated microgravity-induced mice. AB - This study aims to investigate if neural oscillations can play a role as a bridge between the alteration of glutamatergic system and emotional behaviors in simulated microgravity (SM) mice. Adult male C57BL/6J mice were randomly divided into two groups: SM and control groups. The animal model was established by hindlimb unloading (HU). The mice were exposed to HU continued for 14days. Weight and sucrose consumption were measured. The degree of anxious and depressive was evaluated by Open field test and Elevated plus maze test. Local field potentials were recorded in the hippocampal perforant path (PP) and dentate gyrus (DG) regions. The NMDAR2A/2B (NR2A/2B) subunits expression and glutamate level were measured by Western and high performance liquid chromatography (HPLC), respectively. After 14days, SM mice exhibited depressive-like and anxiety-like behaviors, while the expression of NR2A/2B subunits and the glutamate level were significantly decreased in the SM group. Moreover, the power distribution of theta (3-8Hz) was decreased by HU, which further significantly attenuated the identical-frequency strength of phase synchronization and the neural information flow at theta rhythm on the PP-DG pathway. The theta-gamma phase synchronization strength was also significantly reduced by HU. The data imply that the neural oscillations measurements is a sign of the emotional behaviors impairment and the glutamatergic system change induced by HU. PMID- 27693608 TI - Fibroblast growth factor 2 alters the oxytocin receptor in a developmental model of anxiety-like behavior in male rat pups. AB - We aimed to determine the short-term effects of early-life stress in the form of maternal separation (MS) on anxiety-like behavior in male rat pups. In order to assess anxiety, we measured 40kHz separation-induced ultrasonic vocalizations (USV) on postnatal day (PND) 11. We further aimed to evaluate the potential involvement of two neurochemical systems known to regulate social and anxiety like behaviors throughout life: oxytocin (OT) and fibroblast growth factor 2 (FGF2). For these purposes, we tested the effects of neonatal administration (on PND1) of an acute dose of FGF2 on USV and its potential interaction with MS. In addition, we validated the anxiolytic effects of OT and measured oxytocin receptor (OTR) gene expression, binding and epigenetic regulation via histone acetylation. Our results show that MS potentiated USV while acute administration of OT and FGF2 attenuated them. Further, we found that both FGF2 and MS increased OTR gene expression and the association of acH3K14 with the OTR promoter in the bed nucleus of the stria terminalis (BNST). Comparable changes, though not as pronounced, were also found for the central amygdala (CeA). Our findings suggest that FGF2 may exert its anxiolytic effects in male MS rats by a compensatory increase in the acetylation of the OTR promoter to overcome reduced OT levels in the BNST. PMID- 27693610 TI - Deficit in emotional learning in neurotrimin knockout mice. AB - Neurotrimin (Ntm) belongs to the IgLON family of cell adhesion molecules with Lsamp, Obcam and kilon that regulate the outgrowth of neurites mostly by forming heterodimers. IgLONs have been associated with psychiatric disorders, intelligence, body weight, heart disease and tumours. This study provides an initial behavioural and pharmacological characterization of the phenotype of Ntm deficient mice. We expected to see at least some overlap with the phenotype of Lsamp-deficient mice as Ntm and Lsamp are the main interaction partners in the IgLON family and are colocalized in some brain regions. However, Ntm-deficient mice displayed none of the deviations in behaviour that we have previously shown in Lsamp-deficient mice, but differently from Lsamp-deficient mice, had a deficit in emotional learning in the active avoidance task. The only overlap was decreased sensitivity to the locomotor stimulating effect of amphetamine in both knockout models. Thus, despite being interaction partners, on the behavioural level Lsamp seems to play a much more central role than Ntm and the roles of these two proteins seem to be complementary rather than overlapping. PMID- 27693611 TI - Data-driven identification of intensity normalization region based on longitudinal coherency of 18F-FDG metabolism in the healthy brain. AB - OBJECTIVES: In brain 18F-FDG PET data intensity normalization is usually applied to control for unwanted factors confounding brain metabolism. However, it can be difficult to determine a proper intensity normalization region as a reference for the identification of abnormal metabolism in diseased brains. In neurodegenerative disorders, differentiating disease-related changes in brain metabolism from age-associated natural changes remains challenging. This study proposes a new data-driven method to identify proper intensity normalization regions in order to improve separation of age-associated natural changes from disease related changes in brain metabolism. METHODS: 127 female and 128 male healthy subjects (age: 20 to 79) with brain18F-FDG PET/CT in the course of a whole body cancer screening were included. Brain PET images were processed using SPM8 and were parcellated into 116 anatomical regions according to the AAL template. It is assumed that normal brain 18F-FDG metabolism has longitudinal coherency and this coherency leads to better model fitting. The coefficient of determination R2 was proposed as the coherence coefficient, and the total coherence coefficient (overall fitting quality) was employed as an index to assess proper intensity normalization strategies on single subjects and age cohort averaged data. Age-associated longitudinal changes of normal subjects were derived using the identified intensity normalization method correspondingly. In addition, 15 subjects with clinically diagnosed Parkinson's disease were assessed to evaluate the clinical potential of the proposed new method. RESULTS: Intensity normalizations by paracentral lobule and cerebellar tonsil, both regions derived from the new data-driven coherency method, showed significantly better coherence coefficients than other intensity normalization regions, and especially better than the most widely used global mean normalization. Intensity normalization by paracentral lobule was the most consistent method within both analysis strategies (subject-based and age-cohort averaging). In addition, the proposed new intensity normalization method using the paracentral lobule generates significantly higher differentiation from the age-associated changes than other intensity normalization methods. CONCLUSION: Proper intensity normalization can enhance the longitudinal coherency of normal brain glucose metabolism. The paracentral lobule followed by the cerebellar tonsil are shown to be the two most stable intensity normalization regions concerning age-dependent brain metabolism. This may provide the potential to better differentiate disease-related changes from age-related changes in brain metabolism, which is of relevance in the diagnosis of neurodegenerative disorders.

In contrast to the spatially local convolutions done in traditional image-based CNNs, our BrainNetCNN is composed of novel edge-to-edge, edge-to-node and node-to-graph convolutional filters that leverage the topological locality of structural brain networks. We apply the BrainNetCNN framework to predict cognitive and motor developmental outcome scores from structural brain networks of infants born preterm. Diffusion tensor images (DTI) of preterm infants, acquired between 27 and 46 weeks gestational age, were used to construct a dataset of structural brain connectivity networks. We first demonstrate the predictive capabilities of BrainNetCNN on synthetic phantom networks with simulated injury patterns and added noise. BrainNetCNN outperforms a fully connected neural-network with the same number of model parameters on both phantoms with focal and diffuse injury patterns. We then apply our method to the task of joint prediction of Bayley-III cognitive and motor scores, assessed at 18 months of age, adjusted for prematurity. We show that our BrainNetCNN framework outperforms a variety of other methods on the same data. Furthermore, BrainNetCNN is able to identify an infant's postmenstrual age to within about 2 weeks. Finally, we explore the high level features learned by BrainNetCNN by visualizing the importance of each connection in the brain with respect to predicting the outcome scores. These findings are then discussed in the context of the anatomy and function of the developing preterm infant brain.

AB - Functional magnetic resonance imaging (fMRI) of the human spinal cord is a difficult endeavour due to the cord's small cross-sectional diameter, signal drop out as well as image distortion due to magnetic field inhomogeneity, and the confounding influence of physiological noise from cardiac and respiratory sources. Nevertheless, there is great interest in spinal fMRI due to the spinal cord's role as the principal sensorimotor interface between the brain and the body and its involvement in a variety of sensory and motor pathologies. In this review, we give an overview of the various methods that have been used to address the technical challenges in spinal fMRI, with a focus on reducing the impact of physiological noise. We start out by describing acquisition methods that have been tailored to the special needs of spinal fMRI and aim to increase the signal to-noise ratio and reduce distortion in obtained images. Following this, we concentrate on image processing and analysis approaches that address the detrimental effects of noise. While these include variations of standard pre processing methods such as motion correction and spatial filtering, the main focus lies on denoising techniques that can be applied to task-based as well as resting-state data sets. We review both model-based approaches that rely on externally acquired respiratory and cardiac signals as well as data-driven approaches that estimate and correct for noise using the data themselves. We conclude with an outlook on techniques that have been successfully applied for noise reduction in brain imaging and whose use might be beneficial for fMRI of the human spinal cord.

AB - RHOA is one of the most extensively investigated members of the Rho GTPase family of proteins and has long been implicated in malignant transformation as well as tumor invasion and metastasis. Recently, revolutionized sequencing platforms have revealed frequent RHOA mutations in a wide variety of human cancers, including angio-immunoblastic T-cell lymphoma, adult T-cell leukemia/lymphoma, germinal center B-cell lymphoma, diffuse-type gastric cancer, and other solid tumors. With their discrete positional distributions and types of amino acid substitution depending on cancer type, different RHOA mutations seem to have unique functional and biological properties. However, their impact on the development of different types of tumors remains controversial. Here, we present an overview of the current understanding of RHOA mutations in human cancers and highlight the unanticipated complexity of their genetic and biological properties.

PMID- 27693614 TI - Neural stress reactivity relates to smoking outcomes and differentiates between mindfulness and cognitive-behavioral treatments. AB - Stress and negative affect are known contributors to drug use and relapse, and several known treatments for addictions include strategies for managing them. In the current study, we administered a well-established stress provocation during functional magnetic resonance imaging (fMRI) to 23 participants who completed either mindfulness training (MT; N=11) or the American Lung Association's Freedom From Smoking (FFS; N=12), which is a cognitive-behavioral treatment (CBT) for smoking cessation. Across the entire sample, we found that stress reactivity in several brain regions including the amygdala and anterior/mid insula was related to reductions in smoking after treatment, as well as at 3-month post-treatment follow-up. Moreover, conjunction analysis revealed that these same regions also differentiated between treatment groups such that the MT group showed lower stress-reactivity compared to the FFS/CBT group. This suggests that reduction in stress reactivity may be one of the mechanisms that underlie the efficacy of MT in reducing smoking over time. The findings have important implications for our understanding of stress, the neural and psychological mechanisms that underlie mindfulness-based treatments, and for smoking cessation treatments more broadly. PMID- 27693617 TI - Myeloid-derived suppressor cells expressing a self-antigen ameliorate experimental autoimmune encephalomyelitis. AB - Previous work by our group showed that transferring bone marrow cells transduced with a self-antigen induced immune tolerance and ameliorated experimental autoimmune encephalomyelitis (EAE), a model of multiple sclerosis (MS). We also found that following retroviral transduction of murine bone marrow (BM) cells, the majority of cells generated and transduced were myeloid-derived suppressor cells (MDSCs). Here, we aimed to determine whether purified antigen-expressing MDSCs have similar therapeutic effects than those of unfractionated BM, and to investigate their potential mechanisms. We performed phenotypic and functional analyses in these cells using the same animal model, and we used purified antigen expressing MDSCs in preventive and therapeutic approaches. These cells exerted therapeutic effects similar to those of BM cells, which depended upon self antigen expression. The majority of monocytic (M)-MDSCs expressed the immunosuppressive molecule programmed death ligand-1 (PD-L1), CD80, CD86 and MHC class II molecules. Additionally, the animals infused with antigen-expressing cells exhibited lower percentages of activated T cells and higher percentages of B cells with a regulatory phenotype (B220+CD1dhigh CD5+) in the spleen than their respective controls. MDSCs expressing self-antigens, alloantigens or therapeutic transgenes are tolerogenic and can be exploited therapeutically in autoimmune diseases, transplantation and in gene therapy, respectively.

AB - The antiepileptic drug phenobarbital (PB) exerts hepatic effect based on indirect activation of the constitutive androstane receptor (CAR) via inhibition of the epidermal growth factor receptor (EGFR) and the kinase Src. It has furthermore been observed that in mice PB suppresses the growth of hepatocellular carcinoma with overactive signaling through the oncogenic Wnt/beta-catenin pathway, thus suggesting an interference of PB with beta-catenin signaling. The present work was aimed to characterize effects of PB on beta-catenin signaling at different cellular levels and to elucidate molecular details of the interaction of PB and beta-catenin in an in vitro system of mouse hepatoma cells. PB efficiently inhibited signaling through beta-catenin. This phenomenon was in-depth characterized at the levels of beta-catenin protein accumulation and transcriptional activity. Mechanistic analyses revealed that the effect of PB on beta-catenin signaling was independent of the activation of CAR and also independent of the cytosolic multi-protein complex responsible for physiological post-translation control of the beta-catenin pathway via initiation of beta catenin degradation. Instead, evidence is provided that PB diminishes beta catenin protein production by inhibition of protein synthesis via signal transduction through EGFR and Src. The proposed mechanism is well in agreement with previously published activities of PB at the EGFR and Src-mediated regulation of beta-catenin mRNA translation. Inhibition of beta-catenin signaling by PB through the proposed mechanism might explain the inhibitory effect of PB on the growth of specific sub-populations of mouse liver tumors. In conclusion, the present data comprehensively characterize the effect of PB on beta-catenin signaling in mouse hepatoma cells in vitro and provides mechanistic insight into the molecular processes underlying the observed effect. PMID- 27693618 TI - Abbreviated environmental enrichment confers neurobehavioral, cognitive, and histological benefits in brain-injured female rats. AB - Environmental enrichment (EE) promotes behavioral recovery after experimental traumatic brain injury (TBI). However, the chronic rehabilitation provided in the laboratory is not analogous to the clinic where physiotherapy is typically limited. Moreover, females make up approximately 40% of the clinical TBI population, yet they are seldom studied in brain trauma. Hence, the goal of this study was to test the hypothesis that abbreviated EE would confer neurobehavioral, cognitive, and histological benefits in brain injured female rats. Anesthetized rats received a cortical impact of moderate-to-severe injury (2.8mm tissue deformation at 4m/s) or sham surgery and then were randomly assigned to groups receiving standard (STD) housing or 4h, 6h, or 24h of EE daily. Motor function (beam-balance/walk and rotarod) was assessed on post operative days 1-5 and every other day from 1 to 19, respectively. Spatial learning/memory (Morris water maze) was evaluated on days 14-19, and cortical lesion volume was quantified on day 21. No statistical differences were appreciated among the sham controls in any assessment and thus the data were pooled. All EE conditions improved motor function and memory retention, but only 6h and 24h enhanced spatial learning relative to STD (p<0.05). Moreover, EE, regardless of duration reduced cortical lesion volume (p<0.05). These data confirm that abbreviated EE confers robust neurobehavioral, cognitive, and histological benefits in TBI female rats, which supports the hypothesis and strengthens the utility of EE as a pre-clinical model of neurorehabilitation. PMID- 27693621 TI - Purification, characterization and the use of recombinant prolyl oligopeptidase from Myxococcus xanthus for gluten hydrolysis. AB - Prolyl oligopeptidase (POP, EC 3.4.21.26) is a cytosolic serine protease that hydrolyses proline containing small peptides. The members of prolyl oligopeptidase family play important roles in many physiological processes such as neurodegenerative diseases, maturation and degradation of peptide hormones. Thus the enzyme has been purified and characterized from various sources to elucidate the potential use as therapeutics. In this study recombinant Myxococcus xanthus prolyl oligopeptidase expressed in E. coli was purified 60.3 fold, using metal-chelate affinity and gel permeation chromatography. The recombinant enzyme had a monomeric molecular weight of 70 kDa. Isoelectric point of the enzyme was found to be approximately 6.3 by two-dimensional polyacrylamide gel electrophoresis. The optimum pH and temperature was estimated as 7.5 and 37 degrees C, respectively. The purified enzyme was stable in a pH range of 6.0-8.5 and thermally stable up to 37 degrees C. The Km and Vmax values were 0.2 mM and 3.42 MUmol/min/mg. The proteolytic activity was inhibited by active-site inhibitors of serine protease, Z-Pro-Prolinal, PMSF, and metal ions, Cd2+, and Hg2+. Furthermore, the hydrolysis efficiency of the recombinant prolyl oligopeptidase was investigated with wheat gluten. PMID- 27693622 TI - Biosynthesis, purification and characterization of beta-1,4-xylanase from a novel mangrove associated actinobacterium Streptomyces olivaceus (MSU3) and its applications. AB - The present study was undertaken to evaluate the xylanolytic properties of an actinobacterium Streptomyces olivaceus (MSU3) isolated from the sediment sample of mangrove environment. It showed highest xylanase activity on initial screening in Breg's mineral salts medium supplemented with 0.5% xylan. Further the organism expressed maximum xylanase production at optimized culture conditions of pH 7, temperature 30 degrees C with 2.5% of inoculum size at 72 h of incubation, the nutrient sources like sucrose (2%) and yeast extract (3%) have observed as best carbon and nitrogen sources respectively. In purification, the xylanase resulted 4.27fold increase with the yield of 15.57% at the final step using sephadex G-75 chromatography. The molecular weight of the purified xylanase was observed as 42 kDa on 10% SDS-PAGE and further identified by MALDI-TOF-MS analysis. It belongs to GH43 family encoded 485 amino acid residues and the xylanase gene isolated using PCR amplification was partially sequenced. It showed 98% sequence similarity to the xylanase gene of S. olivaceus. The maximum activity of purified xylanase was observed at pH 8, temperature 40 degrees C and also the production medium substituted with Fe3+ metal ion, 2.0% xylan and 1.5% NaCl along with Km and Vmax values of 8.16 mg/ml and 250.01 MUg/min/mg, respectively. In xylanolytic hydrolysis of pretreated agro-wastes, especially the sugarcane juice substituted medium yielded maximum (52.19%) reducing sugar, followed by bioethanol production (4.19 g/L) at 72 h of incubation. Based on the results, it could be confirmed that the selected isolate is a potent strain and it can able to produce xylanase through fermentation process and also it can able to convert the pretreated agro wastes into economically important byproduct like bioethanol. PMID- 27693623 TI - Characterization of NoV P particle-based chimeric protein vaccines developed from two different expression systems. AB - The Norovirus (NoV) P domain, with three surface loops for foreign antigen insertion, has been demonstrated as an excellent platform for antigen presentation and novel vaccine development. The P domain alone can self-assemble into a P dimer, 12-mer small particle or 24-mer P particle, and vaccines based on those particles may elicit different levels of immunogenicity. Currently, P particles are generally produced in soluble expression systems in Escherichia coli, mainly in the 24-mer form. However, the low yield of the soluble protein has hindered further clinical applications of P particle-based protein vaccines. In this study, we inserted the Alzheimer's disease (AD) immunogen Abeta1-6 into the three loops of the P particle to generate an AD protein vaccine. To increase the yield of this chimeric protein, we tested the generation of proteins in a soluble expression system and an inclusion body expression system separately in E. coli. The result showed that the inclusion body expression system could greatly enhance the product yield of the chimeric protein compared with the soluble expression system. The refolded protein from the inclusion bodies was mainly in the 12-mer form, while the protein generated from the soluble supernatant was mainly in the 24-mer form. Moreover, the immunogenicity of soluble proteins was significantly stronger than that of the refolded proteins. Thus, comparisons between the two expression methods suggested that the soluble expression system generated chimeric P particles with better immunogenicity, while inclusion body expression system yielded more P particle proteins. PMID- 27693625 TI - A neural mechanism of dynamic gating of task-relevant information by top-down influence in primary visual cortex. AB - Visual recognition involves bidirectional information flow, which consists of bottom-up information coding from retina and top-down information coding from higher visual areas. Recent studies have demonstrated the involvement of early visual areas such as primary visual area (V1) in recognition and memory formation. V1 neurons are not passive transformers of sensory inputs but work as adaptive processor, changing their function according to behavioral context. Top down signals affect tuning property of V1 neurons and contribute to the gating of sensory information relevant to behavior. However, little is known about the neuronal mechanism underlying the gating of task-relevant information in V1. To address this issue, we focus on task-dependent tuning modulations of V1 neurons in two tasks of perceptual learning. We develop a model of the V1, which receives feedforward input from lateral geniculate nucleus and top-down input from a higher visual area. We show here that the change in a balance between excitation and inhibition in V1 connectivity is necessary for gating task-relevant information in V1. The balance change well accounts for the modulations of tuning characteristic and temporal properties of V1 neuronal responses. We also show that the balance change of V1 connectivity is shaped by top-down signals with temporal correlations reflecting the perceptual strategies of the two tasks. We propose a learning mechanism by which synaptic balance is modulated. To conclude, top-down signal changes the synaptic balance between excitation and inhibition in V1 connectivity, enabling early visual area such as V1 to gate context-dependent information under multiple task performances.

AB - Bovine herpesvirus (BoHV) glycoprotein E (gE) is a non-essential envelope glycoprotein and the deletion of gE has been used to develop BoHV-1 and BoHV-5 differential vaccine strains. The DIVA (Differentiation of Infected from Vaccinated Animals) strategy, using marker vaccines based on gE-negative BoHV strains, allows the identification of vaccinated or infected animals in immunoassays designed to detect anti-gE antibodies. In this study a codon optimized synthetic sequence of gE containing highly conserved regions from BoHV 1 and BoHV-5 was expressed in Pichia pastoris. Following expression, the recombinant gE (rgE) was secreted and purified from the culture medium. The rgE was identified by Western blotting (WB) using sera from cattle naturally infected with BoHV-1 and/or BoHV-5, or sera from bovines experimentally infected with wild type BoHV-5. Sera collected from cattle vaccinated with a BoHV-5 gI/gE/US9- marker vaccine failed to recognise rgE. Expression of rgE, based on a sequence containing highly conserved regions from BoHV-1 and BoHV-5, in P. pastoris enabled the production of large quantities of rgE suitable for use in immunoassays for the differentiation vaccinated or infected cattle. PMID- 27693626 TI - A general resolution of intractable problems in polynomial time through DNA Computing. AB - Based on a set of known biological operations, a general resolution of intractable problems in polynomial time through DNA Computing is presented. This scheme has been applied to solve two NP-Hard problems (Minimization of Open Stacks Problem and Matrix Bandwidth Minimization Problem) and three co-NP Complete problems (associated with Hamiltonian Path, Traveling Salesman and Hamiltonian Circuit), which have not been solved with this model. Conclusions and open questions concerning the computational capacity of this model are presented, and research topics are suggested. PMID- 27693627 TI - Effects of fasting and refeeding on gene expression of slc15a1a, a gene encoding an oligopeptide transporter (PepT1), in the intestine of Mozambique tilapia. AB - The tissue distribution of slc15a1a, a gene that encodes an oligopeptide transporter, PepT1, and its response to fasting and refeeding were investigated in the intestinal epithelium of Mozambique tilapia for a better understanding of its role on nutrient absorption. The slc15a1a was predominantly expressed in the absorptive epithelia of the anterior part of the intestine, suggesting that digested oligopeptides are primarily absorbed in the anterior intestine. The response of slc15a1a to fasting was evaluated at 1, 2, 4, 7 and 14days after the last feeding. Fasting revealed a biphasic effect, where short-term fasting significantly upregulated slc15a1a expression and long-term fasting resulted in downregulation. The expression level continued to decrease and fell below the pre fasted level from day 4 to 14. Proximal (the hepatic loop, HL) and distal parts (the proximal major coil, PMC) of the anterior intestine showed different magnitudes of responses to fasting; slc15a1a expression in the PMC showed greater upregulation and downregulation than that in the HL. Refeeding significantly stimulated slc15a1a expression at day 3, although the expression did not exceed the pre-fasted level. Observed responses of slc15a1a to fasting and refeeding suggest that the expression level of this gene can serve as a sensitive indicator of the changes that may occur in altering nutritional conditions. These findings contribute to a better understanding of the role of PepT1 in nutrition and of the complex mechanisms underlying the absorption of oligopeptides and amino acids in the intestine, and may lead to development of possible means to manipulate the absorption processes for the improvement of growth and other metabolic and physiological conditions in fish. PMID- 27693628 TI - Molecular and functional characterization of a fads2 orthologue in the Amazonian teleost, Arapaima gigas. AB - The Brazilian teleost Arapaima gigas is an iconic species of the Amazon. In recent years a significant effort has been put into the farming of arapaima to mitigate overfishing threats. However, little is known regarding the nutritional requirements of A. gigas in particular those for essential fatty acids including the long-chain polyunsaturated fatty acids (LC-PUFA) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The ability to biosynthesize LC-PUFA is dependent upon the gene repertoire of fatty acyl desaturases (Fads) and elongases (Elovl), as well as their fatty acid specificities. In the present study we characterized both molecularly and functionally an orthologue of the desaturase fatty acid desaturase 2 (fads2) from A. gigas. The isolated sequence displayed the typical desaturase features, a cytochrome b5-domain with the heme-binding motif, two transmembrane domains and three histidine-rich regions. Functional characterization of A. gigas fads2 showed that, similar to other teleosts, the A. gigas fads2 exhibited a predominant Delta6 activity complemented with some capacity for Delta8 desaturation. Given that A. gigas belongs to one of the oldest teleostei lineages, the Osteoglossomorpha, these findings offer a significant insight into the evolution LC-PUFA biosynthesis in teleosts. PMID- 27693629 TI - Activation of the Tor/Myc signaling axis in intestinal stem and progenitor cells affects longevity, stress resistance and metabolism in drosophila. AB - The TOR (target of rapamycin) signaling pathway and the transcriptional factor Myc play important roles in growth control. Myc acts, in part, as a downstream target of TOR to regulate the activity and functioning of stem cells. Here we explore the role of TOR-Myc axis in stem and progenitor cells in the regulation of lifespan, stress resistance and metabolism in Drosophila. We found that both overexpression of rheb and myc-rheb in midgut stem and progenitor cells decreased the lifespan and starvation resistance of flies. TOR activation caused higher survival under malnutrition conditions. Furthermore, we demonstrate gut-specific activation of JAK/STAT and insulin signaling pathways to control gut integrity. Both genetic manipulations had an impact on carbohydrate metabolism and transcriptional levels of metabolic genes. Our findings indicate that activation of the TOR-Myc axis in midgut stem and progenitor cells influences a variety of traits in Drosophila. PMID- 27693630 TI - Acetyl-CoA carboxylase rewires cancer metabolism to allow cancer cells to survive inhibition of the Warburg effect by cetuximab. AB - Cetuximab inhibits HIF-1-regulated glycolysis in cancer cells, thereby reversing the Warburg effect and leading to inhibition of cancer cell metabolism. AMP activated protein kinase (AMPK) is activated after cetuximab treatment, and a sustained AMPK activity is a mechanism contributing to cetuximab resistance. Here, we investigated how acetyl-CoA carboxylase (ACC), a downstream target of AMPK, rewires cancer metabolism in response to cetuximab treatment. We found that introduction of experimental ACC mutants lacking the AMPK phosphorylation sites (ACC1_S79A and ACC2_S212A) into head and neck squamous cell carcinoma (HNSCC) cells protected HNSCC cells from cetuximab-induced growth inhibition. HNSCC cells with acquired cetuximab resistance contained not only high levels of T172 phosphorylated AMPK and S79-phosphorylated ACC1 but also an increased level of total ACC. These findings were corroborated in tumor specimens of HNSCC patients treated with cetuximab. Cetuximab plus TOFA (an allosteric inhibitor of ACC) achieved remarkable growth inhibition of cetuximab-resistant HNSCC xenografts. Our data suggest a novel paradigm in which cetuximab-mediated activation of AMPK and subsequent phosphorylation and inhibition of ACC is followed by a compensatory increase in total ACC, which rewires cancer metabolism from glycolysis-dependent to lipogenesis-dependent. PMID- 27693631 TI - Disrupting MALAT1/miR-200c sponge decreases invasion and migration in endometrioid endometrial carcinoma. AB - Endometrioid endometrial carcinoma (EEC) is the most common gynecologic malignancy around the world. Epithelial-to-mesenchymal transition (EMT) is a core process during EEC cell invasion. The abnormal expression of the long noncoding RNA metastasis associated lung adenocarcinoma transcript 1 (MALAT1) or miR-200 family members were shown to facilitate EMT in multiple human cancers, but the regulatory mechanism by which MALAT1 and miR-200 act remains unknown. Previous studies have shown that miR-200 family members are enriched in EEC as well as melanoma and some ovarian carcinomas. In the present study, we first showed that miR-200c levels were higher in most EEC specimens than in non-tumor tissues, while MALAT1 levels were lower. Moreover, we found that miR-200c bound directly to MALAT1 using luciferase reporter and qRT-PCR assays. MALAT1 and miR-200c are reciprocally repressed, and TGF-beta increased MALAT1 expression by inhibiting miR-200c. When the interaction between miR-200c/MALAT1 was interrupted, the invasive capacity of EEC cells was decreased and EMT markers expression were altered in vitro. A xenograft tumor model was used to show that targeting the miR 200c/MALAT1 axis inhibited EEC growth and EMT-associated protein expression in vivo. In summary, miR-200c/MALAT1 axis is a target with therapeutic potential in EEC. However, different expression model of miR-200c and MALAT1 in EEC with that in other organ carcinomas needs further mechanism researches. PMID- 27693632 TI - Comparative analysis of the relative potential of silver, Zinc-oxide and titanium dioxide nanoparticles against UVB-induced DNA damage for the prevention of skin carcinogenesis. AB - Sunscreen formulations containing UVB filters, such as Zinc-oxide (ZnO) and titanium-dioxide (TiO2) nanoparticles (NPs) have been developed to limit the exposure of human skin to UV-radiations. Unfortunately, these UVB protective agents have failed in controlling the skin cancer incidence. We recently demonstrated that silver nanoparticles (Ag-NPs) could serve as novel protective agents against UVB-radiations. Here our goal was to perform comparative analysis of direct and indirect UVB-protection efficacy of ZnO-, TiO2- and Ag-NPs. Sun protection-factor calculated based on their UVB-reflective/absorption abilities was the highest for TiO2-NPs followed by Ag- and ZnO-NPs. This was further confirmed by studying indirect protection of UVB radiation-induced death of HaCaT cells. However, only Ag-NPs were active in protecting HaCaT cells against direct UVB-induced DNA-damage by repairing bulky-DNA lesions through nucleotide-excision repair mechanism. Moreover, Ag-NPs were also effective in protecting HaCaT cells from UVB-induced oxidative DNA damage by enhancing SOD/CAT/GPx activity. In contrast, ZnO- and TiO2-NPs not only failed in providing any direct protection from DNA-damage, but rather enhanced oxidative DNA-damage by increasing ROS production. Together, these findings raise concerns about safety of ZnO- and TiO2 NPs and establish superior protective efficacy of Ag-NPs. PMID- 27693633 TI - Hypoxia induces TWIST-activated epithelial-mesenchymal transition and proliferation of pancreatic cancer cells in vitro and in nude mice. AB - The epithelial-mesenchymal transition (EMT) plays a crucial role in pancreatic ductal adenocarcinoma (PDAC) development and progression. TWIST activated by intra-tumoral hypoxia functions to promote the EMT. We hypothesized that TWIST and the downstream gene pathway could mediate PDAC progression under hypoxia. Therefore, 90 PDAC tissue specimens were immunostained for TWIST and other proteins. Pancreatic cancer cell lines were used for in vitro experiments and nude mice were used to confirm the in vivo data. Expression of TWIST and HIF 1alpha proteins was significantly upregulated, whereas expression of E-cadherin and p16 was down-regulated in PDAC tissues compared to that of non-tumor tissues and in tumor tissues obtained from patients with tumor involving splenic artery than those without splenic artery involvement. Up-regulated TWIST in tumor tissues were associated with worse prognosis in PDAC patients. The in vitro data showed that HIF-1alpha-induced TWIST overexpression promoted tumor cell growth and EMT under a hypoxic condition via TWIST interaction with Ring1B and EZH2. In vivo data showed that TWIST overexpression or a hypoxic condition induce xenograft growth, abdominal metastasis and low mouse survival, whereas knockdown of either Ring1B or EZH2 expression suppressed tumor xenograft growth and metastasis and prolonged survival of nude mice. TWIST was the key player in promotion of pancreatic cancer development and metastasis under a hypoxic condition through interaction with Ring1B and EZH2 to regulate expression of E cadherin and p16 proteins in pancreatic cancer cells. PMID- 27693634 TI - pVHL mediates K63-linked ubiquitination of IKKbeta, leading to IKKbeta inactivation. AB - Nuclear factor (NF)-kappaB is a transcription factor that plays an important role in many biological functions. Regulation of NF-kappaB activity is complicated, and ubiquitination is essential for NF-kappaB activation. Hypoxia can activate NF kappaB. However, the underlying mechanism remains unclear. pVHL is a tumour suppressor and functions as an adaptor of E3-ligase. In this study, we demonstrated that pVHL inhibits NF-kappaB by mediating K63-ubiquitination of IKKbeta, which is dependent on oxygen. We found that pVHL mediates K63-linked ubiquitination of IKKbeta, which is an upstream regulator of NF-kappaB. The pVHL mediated K63-ubiquitination of IKKbeta prevents TAK1 binding, which leads to the inhibition of IKKbeta phosphorylation and NF-kappaB activation. pVHL-mediated K63 ubiquitination of IKKbeta is inhibited under hypoxia. DMOG, which is a specific inhibitor of prolyl hydroxylases, also suppresses K63-ubiquitination of IKKbeta. Prolyl hydroxylase (PHD) 1 enhances K63-ubiquitination of IKKbeta and inhibits IKKbeta phosphorylation. These results suggest a novel function for pVHL in mediating K63-linked ubiquitination of IKKbeta, which plays a role in the regulation of IKK/NF-kappaB signalling. The results also provide new insight into the mechanism of NF-kappaB activation through hypoxia. PMID- 27693635 TI - Immunological, anti-angiogenic and clinical effects of intratumoral interleukin 12 electrogene therapy combined with metronomic cyclophosphamide in dogs with spontaneous cancer: A pilot study. AB - The immunological, anti-angiogenic and clinical effects of metronomic cyclophosphamide and 3 consecutive intratumoral interleukin (IL)-12 gene therapy (electrogene therapy (EGT)) treatments were evaluated in 6 dogs with spontaneous cancer. In all dogs, a decrease in peripheral leukocytes 2 days after IL-12 EGT coincided with erythema and swelling of the tumor. In the tumor, a transient increase in IL-12 levels was measured, whereas a continuous increase in interferon gamma (IFNgamma) and thrombospondin 1 (TSP-1) were determined in contrast to a continuous decrease in vascular endothelial growth factor (VEGF). In the serum, a transient increase in IL-12 and IL-10 levels were noted in contrast to a transient decrease in VEGF and TSP-1. The treatment resulted in a significant anti-angiogenic effect. Although all primary tumors continued to progress in time, this progression was slower than before treatment according to the contrast-enhanced ultrasound data. Besides the encouraging immunostimulatory and anti-angiogenic effects observed in all dogs we also noticed in 4 out of 6 dogs clinically relevant improvements in quality of life and weight. These results hold great promise for combinatorial strategies of IL-12 EGT and metronomic chemotherapy with conventional antitumor (immuno)therapies. PMID- 27693636 TI - Hepatitis B virus mRNAs functionally sequester let-7a and enhance hepatocellular carcinoma. AB - Hepatitis B virus (HBV) infection induces hepatocarcinogenesis and malignant progression, yet global effects of the redundant viral mRNAs produced during infection are unexplored. Here, microRNA (miRNA) target prediction and whole genome expression analysis revealed that HBV pre-C/C mRNA leads to upregulation of multiple let-7a targeted genes. A let-7a complementary region from nt 86 to 108 in the HBV genome was then identified in HBV pre-C/C, pre-S, and S mRNAs. The let-7a sequestration effect by HBV mRNAs was observed under transfection and virus infection, which is dependent on the let-7a response sequence. Moreover, we found reduced AGO2 binding, as well as functional mRNA and protein de-repression of let-7a targets (e.g., c-myc, K-RAS, and CCR7), upon viral mRNA expression. Let 7a levels in the liver were significantly decreased in hepatocellular carcinoma (HCC) patients with HBV infection and were negatively correlated with intrahepatic pre-S2 mRNA levels. Finally, both in vitro and in vivo studies demonstrated that let-7a inhibition by HBV mRNAs resulted in enhanced HCC cell colony formation and tumor growth, providing evidence of the oncogenic potential of HBV mRNAs. PMID- 27693637 TI - The A2b adenosine receptor antagonist PSB-603 promotes oxidative phosphorylation and ROS production in colorectal cancer cells via adenosine receptor-independent mechanism. AB - PURPOSE: Adenosine is a multifaceted regulator of tumor progression. It modulates immune cell activity as well as acting directly on tumor cells. The A2b adenosine receptor (A2b-AR) is thought to be an important mediator of these effects. In this study we sought to analyze the contribution of the A2b-AR to the behavior of colorectal cancer cells. PRINCIPAL RESULTS: The A2b-AR antagonist PSB-603 changed cellular redox state without affecting cellular viability. Quantification of cellular bioenergetics demonstrated that PSB-603 increased basal oxygen consumption rates, indicative of enhanced mitochondrial oxidative phosphorylation. Unexpectedly, pharmacological and genetic approaches to antagonize AR-related signalling of PSB-603 did not abolish the response, suggesting that it was AR-independent. PSB-603 also induced acute increases in reactive oxygen species, and PSB-603 synergized with chemotherapy treatment to increase colorectal cancer cell death, consistent with the known link between cellular metabolism and chemotherapy response. MAJOR CONCLUSIONS: PSB-603 alters cellular metabolism in colorectal cancer cells and increases their sensitivity to chemotherapy. Although requiring more mechanistic insight into its A2b-AR independent activity, our results show that PSB-603 may have clinical value as an anti-colorectal cancer therapeutic.

AB - Acriflavine (ACF), a known antibacterial drug, has recently been recognized as a suitable candidate for cancer chemotherapy. However, the molecular target of ACF is not fully understood, which limits its application in cancer therapy. In this study, we established a structure-specific probe-based pull-down approach to comprehensively profile the potential target of ACF, and we identified DNA dependent protein kinase catalytic subunit (DNA-PKcs) as the direct target of ACF. Since DNA-PKcs facilitates the repair process following DNA double-strand breaks, we further developed a drug combination strategy that combined ACF with the bifunctional alkylating agent melphalan, which exerted a p53-dependent synergistic efficacy against human cancer cells both in vitro and in vivo. With these findings, our study demonstrated that structure-specific probe-based pull down approaches can be used to identify new functional target of drug, and provided novel opportunities for the development of ACF-based antitumor chemotherapies.

AB - Oral squamous cell carcinoma (OSCC) is genetically highly heterogeneous, which contributes to the challenges of treatment. To create an in vitro model that accurately reflects this heterogeneity, we generated a panel of HPV-negative OSCC cell lines. By whole exome sequencing of the lines and matched patient blood samples, we demonstrate that the mutational spectrum of the lines is representative of primary OSCC in The Cancer Genome Atlas. We show that loss of function mutations in FAT1 (an atypical cadherin) and CASP8 (Caspase 8) frequently occur in the same tumour. OSCC cells with inactivating FAT1 mutations exhibited reduced intercellular adhesion. Knockdown of FAT1 and CASP8 individually or in combination in OSCC cells led to increased cell migration and clonal growth, resistance to Staurosporine-induced apoptosis and, in some cases, increased terminal differentiation. The OSCC lines thus represent a valuable resource for elucidating the impact of different mutations on tumour behaviour. PMID- 27693640 TI - MELK is an oncogenic kinase essential for early hepatocellular carcinoma recurrence. AB - Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths worldwide. Many kinases have been found to be intimately involved in oncogenesis and the deregulation of kinase function has emerged as a major mechanism by which cancer cells evade normal physiological constraints on growth and survival. Previously, we have performed gene expression profile analysis on HCC samples and have identified a host of kinases that are remarkably overexpressed in HCC. Among these, the Maternal Embryonic Leucine Zipper Kinase (MELK) is highly overexpressed in HCC and its overexpression strongly correlates with early recurrence and poor patients' survival. Silencing MELK inhibited cell growth, invasion, stemness and tumorigenicity of HCC cells by inducing apoptosis and mitosis. We further showed that the overexpression of MELK in HCC samples strongly correlated with the cell cycle- and mitosis-related genes which are directly regulated as part of the forkhead transcription factor FoxM1-related cell division program. Together, our data establish MELK as an oncogenic kinase involved in the pathogenesis and recurrence of HCC and could provide a promising molecular target to develop therapeutic strategies for patients with advanced HCC. PMID- 27693641 TI - Microbicidal activity measured by flow cytometry: Optimization and standardization for detection of primary and functional deficiencies. AB - : Microbicidal activity is related to the production of reactive oxygen species (ROS) that can be measured by flow-cytometry using rhodamine 123 (R123). Few assays have been proposed to measure ROS production, usually on heparinized samples but none of them is standardized. Here we propose to improve the test by selecting polymorphonuclears (PMN) and monocytes, labelled and activated in one step to keep the test short, and to standardize the process even between different systems (i.e. NaviosTM and FACSCantoTM) using fluorescence intensity target setting ("FITS"). We applied this test on 15 patients without inflammation, 19 patients from an intensive care unit (ICU) and 11 healthy volunteers. RESULTS: Provided calcium restitution, we show that the test can be performed on EDTA that is a better sample preservative. The results were highly correlated between instruments (r2=0.898). PMN CD16 (and not CD14) expression was altered under stimulation with E. coli (MdFI=239.3+/-93.5) or PMA (139.7+/-76.8) as compared to resting sample (307.6+/-145.1). RH123 was strongly and homogeneously induced by PMA (14.2+/-6.6) and more heterogeneously by E. coli (MdFI 21.9+/-23.4) as compared to unstimulated PNN (0.9+/-1.3, p<0.0001). The test is useful not only for genetic disorders but also for secondary deficiencies as observed in ICU (E. coli RH123 MFI=10.5+/-11.1 patients vs 30.1+/-26.5 in healthy donors). In ICU, CD16 expression was already altered on unstimulated samples (MdFI=197.4+/-131.2 vs 418, 2+/-81.3 in healthy donors; p<=0.0001). Bacterial stimulation was dependent of the complement that partly explains deficiency to bacterial stimulus in ICU patients. PMID- 27693642 TI - CoVaccine HTTM adjuvant is superior to Freund's adjuvants in eliciting antibodies against the endogenous alarmin HMGB1. AB - Adjuvants are used to enhance the immune response against specific antigens for the production of antibodies, with the choice of adjuvant most critical for poorly immunogenic and self-antigens. This study quantitatively and qualitatively evaluated CoVaccine HTTM and Freund's adjuvants for eliciting therapeutic ovine polyclonal antibodies targeting the endogenous alarmin, high mobility group box-1 (HMGB1). Sheep were immunised with HMGB1 protein in CoVaccine HTTM or Freund's adjuvants, with injection site reactions and antibody titres periodically assessed. The binding affinity of antibodies for HMGB1 and their neutralisation activity was determined in-vitro, with in vivo activity confirmed using a murine model of endotoxemia. Results indicated that CoVaccine HTTM elicited significantly higher antibody tires with stronger affinity and more functional potency than antibodies induced with Freund's adjuvants. These studies provide evidence that CoVaccine HTTM is superior to Freund's adjuvants for the production of antibodies to antigens with low immunogenicity and supports the use of this alternative adjuvant for clinical and experimental use antibodies. PMID- 27693643 TI - Timing of upper endoscopy influences outcomes in patients with acute nonvariceal upper GI bleeding. AB - BACKGROUND AND AIMS: Current guidelines advise that upper endoscopy be performed within 24 hours of presentation in patients with acute nonvariceal upper GI bleeding (UGIB). However, the role of urgent endoscopy (<12 hours) is controversial. Our aim was to assess whether patients admitted with acute nonvariceal UGIB with lower-risk versus high-risk bleeding have different outcomes with urgent compared with nonurgent endoscopy. METHODS: A retrospective cohort study was conducted of patients admitted to an academic hospital with nonvariceal UGIB. The primary outcome was a composite of inpatient death from any cause, inpatient rebleeding, need for surgical or interventional radiologic intervention, or endoscopic reintervention. The Glasgow-Blatchford score (GBS) was calculated; lower risk was defined as a GBS < 12, and high risk was defined as a GBS >= 12. RESULTS: Of 361 patients, 37 patients (10%) experienced the primary outcome. Patients who underwent urgent endoscopy had a greater than 5 fold increased risk of reaching the composite outcome (unadjusted odds ratio [OR], 5.6; 95% confidence interval [CI], 2.8-11.4; P < .001). Lower-risk patients who were taken urgently to endoscopy were more likely to reach the composite outcome (adjusted OR, 0.71 per 6 hours; 95% CI, 0.55-0.91; P = .008). However, in the high-risk patients, time to endoscopy was not a significant predictor of the primary outcome (adjusted OR, 0.93 per 6 hours; 95% CI, 0.77-1.13; P = .47; adjusted P for interaction = .039). CONCLUSION: Urgent endoscopy is a predictor of worse outcomes in select patients with acute nonvariceal UGIB. PMID- 27693644 TI - EUS-guided portal pressure gradient measurement with a simple novel device: a human pilot study. AB - BACKGROUND AND AIMS: Portal hypertension (PH) is a serious adverse event of liver cirrhosis. The hepatic venous pressure gradient or portal pressure gradient (PPG) accurately reflects the degree of PH and is the single best prognostic indicator in liver disease. This is usually obtained by interventional radiology (IR), although it is not routinely performed. Recently, we developed a simple novel technique for EUS-guided PPG measurement (PPGM). Our animal studies showed excellent correlation between EUS-PPGM and IR-PPGM. We present the first human pilot study of EUS-PPGM in patients with liver disease. METHODS: EUS-PPGM was performed by experienced endosonographers using a linear echoendoscope, a 25 gauge fine-needle aspiration needle, and a novel compact manometer. The portal vein and hepatic vein (or inferior vena cava) were targeted using a transgastric transduodenal approach. Clinical parameters of PH were evaluated in each patient. Feasibility was defined as successful PPGM in each patient. Safety was based on adverse events captured in a postprocedural interview. RESULTS: Twenty-eight patients underwent EUS-PPGM with 100% technical success and no adverse events. PPG ranged from 1.5 to 19 mm Hg and had excellent correlation with clinical parameters of portal hypertension including the presence of varices (P = .0002), PH gastropathy (P = .007), and thrombocytopenia (P = .036). PPG was increased in patients with high clinical evidence of cirrhosis (P = .005). CONCLUSION: This novel technique of EUS-PPGM using a 25-gauge needle and compact manometer is feasible and appears safe. Given the availability of EUS and the simplicity of the manometry setup, EUS-guided PPG may represent a promising breakthrough for procuring indispensable information in the management of patients with liver disease. PMID- 27693646 TI - Dipotassium ethylenediaminetetraacetic acid is better than tripotassium salt for electrochemiluminescence insulin measurement. AB - Previous studies reported that stability of insulin was better on ethylenediaminetetraacetic acid (EDTA) plasma sample than serum sample. However, those studies used tripotassium EDTA (K3-EDTA) tubes, rather than dipotassium EDTA (K2-EDTA) tubes which are more commonly used in laboratories. We investigated the impact of preservative type of EDTA (K2 or K3) on the stability of C-peptide and insulin at 4 degrees C and at room temperature room. Our study has identified that K2-EDTA achieves longer stability of insulin but does not improve the stability of C-peptide. Insulin and C-peptide are stable 24h on the same K2-EDTA sample at room temperature. PMID- 27693645 TI - Comparing 3 guidelines on the management of surgically removed pancreatic cysts with regard to pathological outcome. AB - BACKGROUND AND AIMS: Currently, 3 guidelines are available for the management of pancreatic cysts. These guidelines vary in their indication for resection of high risk cysts. We retrospectively compared the final pathologic outcome of surgically removed pancreatic cysts with the indications for resection according to 3 different guidelines. METHODS: Patients who underwent pancreatic resection were extracted from our prospective pancreatic cyst database (2006-present). The final histopathologic diagnosis was compared with the initial indication for surgery stated by the guidelines of the International Association of Pancreatology (IAP), European Study Group on Cystic tumors of the Pancreas and American Gastroenterological Association (AGA). We considered surgery in retrospect justified for malignancy, high-grade dysplasia, solid pseudopapillary neoplasms, neuroendocrine tumors or symptom improvement. Furthermore, we evaluated the patients with suspected intraductal papillary mucinous neoplasm (IPMN) separately. RESULTS: Overall, 115 patients underwent pancreatic resection. The preoperative diagnosis was correct in 83 of 115 patients (72%) and differentiation between benign and premalignant in 99 of 115 patients (86%). In retrospect, surgery was justified according to the aforementioned criteria in 52 of 115 patients (45%). For patients with suspected IPMN (n = 75) resection was justified in 36 of 67 (54%), 36 of 68 (53%), and 32 of 54 (59%) of patients who would have had surgery based on the IAP, European, or AGA guidelines, respectively. The AGA guideline would have avoided resection in 21 of 75 (28%) patients, versus 8 of 75 (11%) and 7 of 75 (9%) when the IAP or European guideline would have been applied strictly. Nevertheless, 4 of 33 patients (12%) with high-grade dysplasia or malignancy would have been missed with the AGA guidelines, compared with none with the IAP or European guidelines. CONCLUSION: Although fewer patients undergo unnecessary surgery based on the AGA guidelines, the risk of missing malignancy or high-grade dysplasia with this guideline seems considerably high. PMID- 27693647 TI - Factors Associated with Increased Pain in Primary Dysmenorrhea: Analysis Using a Multivariate Ordered Logistic Regression Model. AB - STUDY OBJECTIVE: In the literature about primary dysmenorrhea (PD), either a pain gradient has been studied just in women with PD or pain was assessed as a binary variable (presence or absence). Accordingly, we decided to carry out a study in young women to determine possible factors associated with intense pain. DESIGN: A cross-sectional observational study. SETTING: A Spanish University in 2016. PARTICIPANTS: A total of 306 women, aged 18-30 years. INTERVENTIONS: A questionnaire was filled in by the participants to assess associated factors with dysmenorrhoea. MAIN OUTCOME MEASURES: Our outcome measure was the Andersch and Milsom scale (grade from 0 to 3). DEFINITION: grade 0 (menstruation is not painful and daily activity is unaffected), grade 1 (menstruation is painful but seldom inhibits normal activity, analgesics are seldom required, and mild pain), grade 2 (daily activity affected, analgesics required and give relief so that absence from work or school is unusual, and moderate pain), and grade 3 (activity clearly inhibited, poor effect of analgesics, vegetative symptoms and severe pain). RESULTS: Factors significantly associated with more extreme pain: a higher menstrual flow (odds ratio [OR], 2.11; P < .001), a worse quality of life (OR, 0.97; P < .001) and use of medication for PD (OR, 8.22; P < .001). CONCLUSION: We determined factors associated with extreme pain in PD in a novel way. Further studies are required to corroborate our results.

PMID- 27693649 TI - MiR-17 targets PTEN and facilitates glial scar formation after spinal cord injuries via the PI3K/Akt/mTOR pathway. AB - OBJECTIVES: We attempted to discover the regulatory role of miR-17 and PTEN in glial scar formation accompanied with spinal cord injuries. METHODS: We established a spinal cord injury (SCI) model in mice which were transfected with different groups of adenoviruses: miR-17 mimics, miR-17 inhibitors and PTEN cDNAs. The improvement of hind limb functions was assessed using the 21-point Basso-Beattie-Bresnahan (BBB) locomotion scale. Immunohistochemistry was used to detect the expression levels of glial fibrillary acidic protein (GFAP), Vimentin and neurofilaments. The expression of miR-17 was quantified using Real time-PCR (RT-PCR). Western blot was conducted to detect the expressions of PTEN, PI3K, Akt, mTOR and S6. Finally, dual luciferase reporter gene assay was conducted to confirm the target relationship between miR-17 and PTEN. RESULTS: The model group exhibited significantly increased expression levels of GFAP, Vimentin, miR-17, PTEN, PI3K, Akt and mTOR. The above trend was enhanced by the transfection of miR 17 mimics (P<0.05). By contrast, the transfection of miR-17 inhibitors significantly down-regulated the expression of GFAP, Vimentin, PTEN, PI3K, Akt, mTOR and p-S6 whereas the expression of GFAP, Vimentin, PI3K, Akt, mTOR and p-S6 in the cells transfected with PTEN cDNAs significantly decreased (P<0.05). Also, the transfection of miR-17 inhibitors and PTEN cDNAs alleviated the astrogliosis in SCI lesions, contributed to the regeneration of nerve filament and improved the functional recovery of the hind limb of mice. Finally, the targeting relationship between miR-17 and PTEN was verified by the dual luciferase reporter gene assay. CONCLUSION: MiR-17 is able to target PTEN and stimulate the PI3K/Akt/mTOR pathway. The formation of glial scar resulted from spinal cord injuries can be reduced either by inhibiting miR-17 or by overexpressing PTEN. PMID- 27693651 TI - DNA-Damage Response RNA-Binding Proteins (DDRBPs): Perspectives from a New Class of Proteins and Their RNA Targets. AB - Upon DNA damage, cells trigger an early DNA-damage response (DDR) involving DNA repair and cell cycle checkpoints, and late responses involving gene expression regulation that determine cell fate. Screens for genes involved in the DDR have found many RNA-binding proteins (RBPs), while screens for novel RBPs have identified DDR proteins. An increasing number of RBPs are involved in early and/or late DDR. We propose to call this new class of actors of the DDR, which contain an RNA-binding activity, DNA-damage response RNA-binding proteins (DDRBPs). We then discuss how DDRBPs contribute not only to gene expression regulation in the late DDR but also to early DDR signaling, DNA repair, and chromatin modifications at DNA-damage sites through interactions with both long and short noncoding RNAs. PMID- 27693652 TI - Responses to abiotic environmental stresses among phylloplane and soil isolates of Beauveria bassiana from two holm oak ecosystems. AB - The response of entomopathogenic mitosporic ascomycete (EMAs) to abiotic stresses might be adapted to the microhabitats in which they inhabit. In phylloplane, these organisms are more exposed to such stresses than they are in soil, which may have led to adaptation to this environment. In the present work, we investigate whether Beauveria bassiana genotype or isolation habitat, i.e., soil or phylloplane, within the same geographic area influences their responses to key environmental stresses, such as temperature, moisture and ultraviolet radiation (UV-B), which can affect their successful use in microbial control. Twenty isolates of B. bassiana obtained from the soil and phylloplane in two ecosystems from southern Spain (holm oak dehesa and a reforested area) were selected to study the population distribution of these isolates and evaluate their thermal, humidity and UV-B requirements. Molecular characterization was conducted by using elongation factor-1alpha (EF-1alpha), the intergenic nuclear region Bloc and 15 microsatellite primers. The cluster analysis based on concatenated EF-1alpha and Bloc sequences grouped the 20 isolates into five clades within B. basiana, with Clades a, b, d and e containing both soil and phylloplane isolates and Clade c including three phylloplane isolates. The dendrogram and the minimal spanning network generated from the genetic distances among multilocus genotypes showed four divergent groups corresponding to the five clades obtained based on the sequence data (Clades b and d were represented in the same group), with a high degree of shared alleles within groups and few alleles shared among groups. Although no relationship was found between MLG and the habitat (soil or phylloplane) of isolation, isolates grouped into Clade c, all of which were collected from phylloplane, formed a separate group of MLGs. To investigate our hypothesis, the responses to temperature (germination and colony growth evaluated in the range 15-35 degrees C), water activity (conidia germination evaluated against values of aw between 1 and 0.862) and UV-B exposure (conidia exposed to 920 or 1200mWm-2 for 2, 4 or 6h) of the soil and phylloplane isolates from the five clades were investigated. No associations of isolate-specific genetic or physiological characteristics with isolate habitat, i.e., soil or phylloplane, were found. These results provide no support for the hypothesis that EMAs strains from the phylloplane have evolved to resist unfavourable environmental conditions. PMID- 27693650 TI - MOMP from Campylobacter jejuni Is a Trimer of 18-Stranded beta-Barrel Monomers with a Ca2+ Ion Bound at the Constriction Zone. AB - The Gram-negative organism Campylobacter jejuni is the major cause of food poisoning. Unlike Escherichia coli, which has two major porins, OmpC and OmpF, C. jejuni has one, termed major outer membrane protein (MOMP) through which nutrients and antibiotics transit. We report the 2.1-A crystal structure of C. jejuni MOMP expressed in E. coli and a lower resolution but otherwise identical structure purified directly from C. jejuni. The 2.1-A resolution structure of recombinant MOMP showed that although the protein has timeric arrangement similar to OmpC, it is an 18-stranded, not 16-stranded, beta-barrel. The structure has identified a Ca2+ bound at the constriction zone, which is functionally significant as suggested by molecular dynamics and single-channel experiments. The water-filled channel of MOMP has a narrow constriction zone, and single molecule studies show a monomeric conductivity of 0.7+/-0.2 nS and a trimeric conductance of 2.2+/-0.2 nS. The ion neutralizes negative charges at the constriction zone, reducing the transverse electric field and reversing ion selectivity. Modeling of the transit of ciprofloxacin, an antibiotic of choice for treating Campylobacter infection, through the pore of MOMP reveals a trajectory that is dependent upon the presence metal ion. PMID- 27693653 TI - Relationships between indoor radon concentrations, thermal retrofit and dwelling characteristics. AB - A monitoring campaign was conducted on a sample of more than 3400 dwellings in Brittany, France from 2011 to 2014. The measurements were collected using one passive dosimeter per dwelling over two months during the heating season, according to the NF ISO 11665-8 (2013) standard. Moreover, building characteristics such as the period of construction, construction material, type of foundation, and thermal retrofit were determined using a questionnaire. The final data set consisted of 3233 houses with the measurement results and the questionnaire answers. Multivariate linear regression models were applied to explore the relationships between the indoor radon concentrations and building characteristics, particularly the thermal retrofit. The geometric mean of the indoor radon concentration was 155 Bq m-3 (with a geometric standard deviation of 3). The houses that had undergone a thermal retrofit had a higher average radon concentration than those that had not, which may have been due to a decrease in air permeability of the building envelope following rehabilitation work that did not systematically include proper management of the ventilation. Other building characteristics, primarily the building material and the foundation type, were associated with the indoor radon concentration. The indoor radon concentrations were higher in older houses built with granite or other stone, with a slab-on grade foundation and without any ventilation system. PMID- 27693654 TI - Assessment of the reduction in levels of exposure to harmful and potentially harmful constituents in Japanese subjects using a novel tobacco heating system compared with conventional cigarettes and smoking abstinence: A randomized controlled study in confinement. AB - Smoking conventional cigarettes (CCs) exposes smokers to harmful and potentially harmful constituents (HPHCs). The Tobacco Heating System 2.2 (THS 2.2), a candidate modified risk tobacco product, was developed to reduce or eliminate the formation of HPHCs, while preserving as much as possible the taste, sensory experience, nicotine delivery profile and ritual characteristics of CC. This randomized, controlled, open-label study in confinement for 5 day exposure aimed to demonstrate the reduction in exposure to selected HPHCs, to assess nicotine uptake and subjective effects, in participants switching to THS 2.2 (n = 80) compared to participants continuing smoking CCs (n = 40) and abstaining from smoking (n = 40). The subjects were randomized according to sex and daily CC consumption. The levels of biomarkers of exposure to HPHCs were significantly reduced in participants switching to THS 2.2, compared to CC use. More importantly, the magnitude of exposure reduction observed was close to that which was seen in participants who abstained from smoking for 5 days, while nicotine uptake was maintained. Reduction in urge-to-smoke was comparable between THS and CC groups, however THS 2.2 was slightly less satisfactory than CCs. The new, alternative tobacco product THS 2.2 was well tolerated.

PMID- 27693656 TI - Association of active human herpesvirus-6 (HHV-6) infection with autoimmune thyroid gland diseases. AB - OBJECTIVES: Viral infections frequently have been cited as important environmental factors implicated in the onset of autoimmune thyroiditis (AIT). The aim of this study was to determine the involvement of HHV-6 infection in the development of autoimmune thyroiditis. METHODS: This study included 45 patients (42 female and 3 male; median age 47.00 IQR 38.50-57.00) with histologically, laboratory, and clinically confirmed autoimmune thyroiditis, as well as 30 autopsied subjects (26 female and 4 male; median age 58.50, IQR 51.50-67.00) without thyroid pathologies and 30 healthy blood donors (25 female and 5 male; median age 33.50, IQR 27.75-44.25) as controls. Results were obtained by applying molecular virology and immunohistochemistry techniques. RESULTS: The presence of persistent HHV-6 infection in AIT patients was significantly higher (p 0.0058) than in the control group (44/45 (98%) vs. 23/30 (77%), respectively). Also, a significantly higher frequency of HHV-6 activation marker (U79/80 mRNA) was found in patients' thyroid gland tissue samples with AIT in comparison with the control group (18/44 (41%) vs. 1/17 (6%), respectively; p 0.0118). The median HHV-6 load was found to be higher in patients with active viral infection than in patients without it (2147, IQR 971-4188 vs. 551, IQR 145-1589 copies/1*106 cells; p 0.003). The presence of HHV-6 antigen expression was demonstrated in intrafollicular cellular clusters and immunohistochemistry indicated thyrocytes in the follicle wall. CONCLUSIONS: These findings provide evidence of strong HHV 6 infection association with AIT development. PMID- 27693657 TI - De-constructing de-escalation. PMID- 27693658 TI - Staphylococcus aureus colonization at ICU admission as a risk factor for developing S. aureus ICU pneumonia. AB - OBJECTIVE: To quantify the incidence of intensive care unit (ICU)-acquired pneumonia caused by Staphylococcus aureus (S. aureus) and its association with S. aureus colonization at ICU admission. METHODS: This was a post-hoc analysis of two cohort studies in critically ill patients. The primary outcome was the incidence of microbiologically confirmed S. aureus ICU-acquired pneumonia. Incidences of S. aureus ICU pneumonia and associations with S. aureus colonization at ICU admission were determined using competing risks analyses. In all ICUs, patients were screened for respiratory tract S. aureus carriage on admission as part of infection control policies. Pooling of data was not deemed possible because of heterogeneity in baseline differences in patient population. RESULTS: The two cohort studies contained data of 9156 ICU patients. The average carriage rate of S. aureus among screened patients was 12.7%. In total, 1185 (12.9%) patients developed ICU pneumonia. Incidences of S. aureus ICU pneumonia were 1.33% and 1.08% in cohorts 1 and 2, respectively. After accounting for competing events, the adjusted subdistribution hazard ratio (SHR) of S. aureus colonization at admission for developing S. aureus ICU pneumonia was 9.55 (95% CI 5.31-17.18) in cohort 1 and 14.54 (95% CI 7.24-29.21) in cohort 2. CONCLUSION: The overall cumulative incidence of S. aureus ICU pneumonia in these ICUs was low. Patients colonized with S. aureus at ICU admission had an up to 15 times increased risk for developing this outcome compared with non-colonized patients.

PMID- 27693660 TI - Increased adult neurogenesis in mice with a permanent overexpression of the postsynaptic 5-HT1A receptor. AB - Depression is among the leading causes of disability and disease burden. Recent studies point to an involvement of altered serotonin1A receptor (5-HT1AR) mediated adult neurogenesis in depression. However, the exact underlying mechanisms remain unclear, mainly due to the complexity of the serotonergic system with its various receptors and their locations. Mice with permanent overexpression of postsynaptic 5-HT1ARs (OE mice) represent a unique tool for investigating the involvement of postsynaptic 5-HT1ARs in this context. Correct 5 HT1AR coupling and functioning has been demonstrated earlier, indicating that more postsynaptic 5-HT1ARs can be activated in these mice. Initially we examined morphometric parameters of the dentate gyrus (DG) and the prefrontal cortex as they are involved in adult hippocampal neurogenesis and/or depression. The volume of the DG in OE mice was increased in comparison to wildtype controls. We therefore investigated parameters of adult neurogenesis by the bromodeoxyuridine method. Proliferation and survival of newborn cells in the DG of OE mice were significantly increased. Significant increases in survived neurons were only detected in the female but not in the male subgroup. Additional staining for early precursor cells (Sox2) and progenitor cells of the neuronal lineage (doublecortin) showed an increase in type-1/2a as well as in type-2b/3 cells in OE mice. Our study suggests a leading role of the postsynaptic 5-HT1AR in adult hippocampal neurogenesis and might open an important link to depression. PMID- 27693661 TI - Effect of muscle relaxation in the foot on simultaneous muscle contraction in the contralateral hand. AB - We investigated the effects of foot muscle relaxation and contraction on muscle activities in the hand on both ipsilateral and contralateral sides. The subjects sat in an armchair with hands in the pronated position. They were able to freely move their right/left hand and foot. They performed three tasks for both ipsilateral (right hand and right foot) and contralateral limb coordination (left hand and right foot for a total of six tasks). These tasks involved: (1) wrist extension from a flexed (resting) position, (2) wrist extension with simultaneous ankle dorsiflexion from a plantarflexed (resting) position, and (3) wrist extension with simultaneous ankle relaxation from a dorsiflexed position. The subjects performed each task as fast as possible after hearing the start signal. Reaction time for the wrist extensor contraction (i.e. the degree to which it preceded the motor reaction time), as observed in electromyography (EMG), became longer when it was concurrently done with relaxation of the ankle dorsiflexor. Also, the magnitude of EMG activity became smaller, as compared with activity when wrist extensor contraction was done alone or with contraction of the ankle dorsiflexor. These effects were observed not only for the ipsilateral hand, but also for the contralateral hand. Our findings suggest that muscle relaxation in one limb interferes with muscle contraction in both the ipsilateral and contralateral limbs. PMID- 27693662 TI - Gastrin-releasing peptide receptor mediates the excitation of preoptic GABAergic neurons by bombesin. AB - Bombesin, a pan agonist of the bombesin-like peptide receptor family, elicits potent hypothermia when applied centrally. The signaling mechanisms involved are not known. Here we report that GABAergic preoptic neurons express gastrin releasing peptide (GRP) receptors and are directly excited by GRP or bombesin. This effect was abolished by a GRP receptor antagonist. A partially overlapping group of preoptic GABAergic neurons express bombesin-like receptor 3 (BRS3), however their activation results in a decrease in firing rate. The excitatory effects of bombesin or GRP were not affected by BRS3 antagonist. GRP activated a Ca2+-dependent inward nonselective cationic current and Ca2+ release from intracellular stores. Our data indicate that GRP receptors mediate the excitatory effects of bombesin in preoptic neurons.

AB - Active amyloid-beta (Abeta) immunotherapy is effective in preventing Abeta deposition, facilitating plaque clearance, and improving cognitive functions in mouse models of Alzheimer's disease (AD). Developing a safe and effective AD vaccine requires a delicate balance between inducing adequate humoral immune responses and avoiding T cell-mediated autoimmune responses. In this study, we designed 2 peptide epitope vaccines, Abeta3-10-KLH and 5Abeta3-10, prepared respectively by coupling Abeta3-10 to the immunogenic carrier protein keyhole limpet hemocyanin (KLH) or by joining 5 Abeta3-10 epitopes linearly in tandem. Young APP/PS1 mice were immunized subcutaneously with Abeta3-10-KLH or 5Abeta3-10 mixed with Freund's adjuvant, and the immunopotencies of these Abeta3-10 peptide vaccines were tested. Abeta3-10-KLH elicited a robust Th2-polarized anti-Abeta antibody response and inhibited Abeta deposition in APP/PS1 mice. However, 5Abeta3-10 did not induce an effective humoral immune response. These results indicated that Abeta3-10-KLH may be a safe and efficient vaccine for AD and that conjugating the antigen to a carrier protein may be more effective than linking multiple peptide antigens in tandem in applications for antibody production and vaccine preparation.

AB - The tendency to disproportionately allocate attention to threat stimuli, to evaluate ambiguous or benign situations as overly threatening, and to exhibit overgeneralised and indiscriminate conditioned fear responses to threat and safe stimuli are hallmark clinical correlates of pathological anxiety. Investigation of these processes in children and adolescents suggests that anxiety-related differences increase with age, and that the specific conditions under which anxious children differ from non-anxious peers are poorly understood. Furthermore, research on cognitive biases and fear conditioning in anxious children and adolescents has progressed as quite distinct lines of investigation. Greater integration of key tenets from each perspective could advance knowledge and provide new directions for improving treatments. The purpose of this paper is threefold. First, we provide a qualitative review of the key principles from cognitive and conditioning theories of anxiety and the associated empirical research, including the underlying neurophysiological basis of these processes in anxious children and adolescents, in order to delineate the conditions under which anxiety-specific differences in threat-related cognitive biases and overgeneralised conditioned fear manifest in children and adolescents. Second, we synthesize these theoretical and empirical insights to propose a cognitive learning formulation of anxiety in children and adolescents. We propose that conditioning and cognitive factors linked to differences in engagement of underlying neural circuits across development contribute to an internal representation of a wide range of stimuli as threatening, to which anxious children and adolescents adopt maladaptive attention regulation patterns of predominantly threat monitoring or threat avoidance. These maladaptive attention regulation patterns differentiate anxious children and adolescents in terms of predominantly high cognitive distress (e.g., worry and rumination) and high behavioural avoidance respectively. Third, we consider the clinical implications of the cognitive-learning formulation for understanding outcomes from current treatments and provide suggestions for improving treatment outcomes. PMID- 27693666 TI - Pericellular plasma clot negates the influence of scaffold stiffness on chondrogenic differentiation. AB - : Matrix stiffness is known to play a pivotal role in cellular differentiation. Studies have shown that soft scaffolds (<2-3kPa) promote cellular aggregation and chondrogenesis, whereas, stiffer ones (>10kPa) show poor chondrogenesis in vitro. In this work we investigated if fibrin matrix from clotted blood can act as a soft surrogate which nullifies the influence of the underlying stiff scaffold, thus promoting chondrogenesis irrespective of bulk scale scaffold stiffness. For this we performed in vitro chondrogenesis on soft (~1.5kPa) and stiff (~40kPa) gelatin scaffolds in the presence and absence of pericellular plasma clot. Our results demonstrated that in absence of pericellular plasma clot, chondrocytes showed efficient condensation and cartilaginous matrix secretion only on soft scaffolds, whereas, in presence of pericellular plasma clot, cell rounding and cartilaginous matrix secretion was observed in both soft and stiff scaffolds. More specifically, significantly higher collagen II, chondroitin sulfate and aggrecan deposition was observed in soft scaffolds, and soft and stiff scaffolds with pericellular plasma clot as compared to stiff scaffolds without pericellular plasma clot. Moreover, collagen type I, a fibrocartilage/bone marker was significantly higher only in stiff scaffolds without plasma clot. Therefore, it can be concluded that chondrocytes surrounded by a soft fibrin network were unable to sense the stiffness of the underlying scaffold/substrate and hence facilitate chondrogenesis even on stiff scaffolds. This understanding can have significant implications in the design of scaffolds for cartilage tissue engineering. STATEMENT OF SIGNIFICANCE: Cell fate is influenced by the mechanical properties of cell culture substrates. Outside the body, cartilage progenitor cells express significant amounts of cartilage-specific markers on soft scaffolds but not on stiff scaffolds. However, when implanted in joints, stiff scaffolds show equivalent expression of markers as seen in soft scaffolds. This disparity in existing literature prompted our study. Our results suggest that encapsulation of cells in a soft plasma clot, present in any surgical intervention, prevents their perception of stiffness of the underlying scaffold, and hence the ability to distinguish between soft and stiff scaffolds vanishes. This finding would aid the design of new scaffolds that elicit cartilage-like biochemical properties while simultaneously being mechanically comparable to cartilage tissue. PMID- 27693664 TI - Pooled patient-level meta-analysis of children and adults completing a computer based anxiety intervention targeting attentional bias. AB - Computer-based approaches, such as Attention Bias Modification (ABM), could help improve access to care for anxiety. Study-level meta-analyses of ABM have produced conflicting findings and leave critical questions unresolved regarding ABM's mechanisms of action and clinical potential. We pooled patient-level datasets from randomized controlled trials of children and adults with high anxiety. Attentional bias (AB) towards threat, the target mechanism of ABM, was tested as an outcome and a mechanistic mediator and moderator of anxiety reduction. Diagnostic remission and Liebowitz Social Anxiety Scale (LSAS) were clinical outcomes available in enough studies to enable pooling. Per-patient data were obtained on at least one outcome from 13/16 eligible studies [86% of eligible participants; n=778]. Significant main effects of ABM on diagnostic remission (ABM-22.6%, control-10.8%; OR=2.57; p=0.006) and AB (beta* (95%CI)= 0.63 (-0.83, -0.42); p<0.00005) were observed. There was no main effect of ABM on LSAS. However, moderator analyses suggested ABM was effective for patients who were younger (<=37y), trained in the lab, and/or assessed by clinicians. Under the same conditions where ABM was effective, mechanistic links between AB and anxiety reduction were supported. Under these specific circumstances, ABM reduces anxiety and acts through its target mechanism, supporting ABM's theoretical basis while simultaneously suggesting clinical indications and refinements to improve its currently limited clinical potential. PMID- 27693667 TI - Neural mechanisms underlying cognitive inflexibility in Parkinson's disease. AB - Cognitive inflexibility is a hallmark of executive dysfunction in Parkinson's disease (PD). This deficit consistently manifests itself in a PD-related increase in the number of perseverative errors committed on the Wisconsin Card Sorting Test (WCST). However, the neural processes underlying perseverative WCST performance in PD are still largely unknown. The present study is the first to investigate the event-related potential (ERP) correlates of cognitive inflexibility on the WCST in PD patients. Thirty-two PD patients and 35 matched control participants completed a computerized version of the WCST while the electroencephalogram (EEG) was recorded. Behavioral results revealed the expected increase in perseverative errors in patients with PD. ERP analysis focused on two established indicators of executive processes: the fronto-central P3a as an index of attentional orienting and the sustained parietal positivity (SPP) as an index of set-shifting processes. In comparison to controls, P3a amplitudes were significantly attenuated in PD patients. Regression analysis further revealed that P3a and SPP amplitudes interactively contributed to the prediction of perseverative errors in PD patients: The number of perseverative errors was only increased when both ERP amplitudes were attenuated. Notably, the two ERP markers of executive processes accounted for more than 40% of the variance in perseverative errors in PD patients. We conclude that cognitive inflexibility in PD occurs when the neural bases of multiple executive processes are affected by the pathophysiology of PD. The combined measurement of P3a and SPP might yield an electrophysiological marker of cognitive inflexibility in PD.

AB - Disturbances in implicit self-processing have been reported both in psychotic patients with bipolar disorder (BD) and schizophrenia. It remains unclear whether these two psychotic disorders show disturbed functional connectivity during explicit self-reflection, which is associated with social functioning and illness symptoms. Therefore, we investigated functional connectivity during explicit self reflection in BD with past psychosis and schizophrenia. Twenty-three BD-patients, 17 schizophrenia-patients and 21 health controls (HC) performed a self-reflection task, including the conditions self-reflection, close other-reflection and semantic control. Functional connectivity was investigated with generalized psycho-physiological interaction (gPPI). During self-reflection compared to semantic, BD-patients had decreased connectivity between several cortical-midline structures (CMS) nodes (i.e., anterior cingulate cortex, ventromedial prefrontal cortex), the insula and the head of the caudate while HC showed increased connectivities. Schizophrenia-patients, during close other-reflection compared to semantic, demonstrated reduced ventral-anterior insula-precuneus/posterior cingulate cortex (PCC) functional connectivity, whereas this was increased in HC. There were no differences between BD and schizophrenia during self- and close other-reflection. We propose that decreased functional connectivity between the CMS nodes/insula and head of the caudate in BD-patients may imply a reduced involvement of the motivational system during self-reflection; and the reduced functional connectivity between the ventral-anterior insula and precuneus/PCC during close other-reflection in schizophrenia-patients may subserve difficulties in information integration of autobiographical memory and emotional awareness in relation to close others. These distinctive impaired patterns of functional connectivity in BD and schizophrenia (compared to HC) deserve further investigation to determine their robustness and associations with differences in clinical presentation. PMID- 27693669 TI - Polymorphisms of Interlukin-1beta rs16944 confer susceptibility to myelodysplastic syndromes. AB - Genetic factors have been shown to be associated with Myelodysplastic syndromes (MDS) susceptibility. In recent years, the role of inflammation in the promotion of tumor growth is supported by a broad range of experimental and clinical evidence. But the relationship between polymorphisms in NOD-like receptor protein 3 (NLRP3) inflammasome and MDS is rarely reported. Thus, we conducted a case control study, and genotyped five single nucleotide polymorphisms (SNPs) (NLRP3, IL-1beta, IL-18, CARD8, and NF-kappaB) in MDS patients and healthy controls. The association of different genotypes with patient characteristics was analyzed. Comparing MDS patients with controls, GG genotype of IL-1beta (rs16944) was observed to be associated with a significantly increased risk of MDS 78/166 (48.8%) vs 26/96 (27.0%), OR=2.1, CI (1.0-4.4). No significant association was identified regarding the rest of investigated polymorphisms and MDS susceptibility. Complex karyotypes were more frequent in patients with GG genotype of IL-1beta (rs16944). Patients with IL-1beta polymorphisms (rs16944) GG and GA had lower hemoglobin than those without. Patients with IL-1beta polymorphisms (rs16944) GG had higher IPSS scores than those without IL-1beta polymorphisms. In conclusion, our present data shows that the IL-1beta polymorphisms (rs16944) GG were frequently occurred in MDS. IL-1beta (rs16944) GG genotype might serve as a novel biomarker and potential targets for MDS. PMID- 27693670 TI - [18F]Fluoro-azomycin-2'-deoxy-beta-d-ribofuranoside - A new imaging agent for tumor hypoxia in comparison with [18F]FAZA. AB - INTRODUCTION: Radiolabeled 2-nitroimidazoles (azomycins) are a prominent class of biomarkers for PET imaging of hypoxia. [18F]Fluoro-azomycin-alpha-arabinoside ([18F]FAZA) - already in clinical use - may be seen as alpha-configuration nucleoside, but enters cells only via diffusion and is not transported by cellular nucleoside transporters. To enhance image contrast in comparison to [18F]FAZA our objective was to 18F-radiolabel an azomycin-2'-deoxyriboside with beta-configuration ([18F]FAZDR, [18F]-beta-8) to mimic nucleosides more closely and comparatively evaluate it versus [18F]FAZA. METHODS: Precursor and cold standards for [18F]FAZDR were synthesized from methyl 2-deoxy-d-ribofuranosides alpha- and beta-1 in 6 steps yielding precursors alpha- and beta-5. beta-5 was radiolabeled in a GE TRACERlab FXF-N synthesizer in DMSO and deprotected with NH4OH to give [18F]FAZDR ([18F]-beta-8). [18F]FAZA or [18F]FAZDR was injected in BALB/c mice bearing CT26 colon carcinoma xenografts, PET scans (10min) were performed after 1, 2 and 3h post injection (p.i.). On a subset of mice injected with [18F]FAZDR, we analyzed biodistribution. RESULTS: [18F]FAZDR was obtained in non-corrected yields of 10.9+/-2.4% (9.1+/-2.2GBq, n=4) 60min EOB, with radiochemical purity >98% and specific activity >50GBq/MUmol. Small animal PET imaging showed a decrease in uptake over time for both [18F]FAZDR (1h p.i.: 0.56+/-0.22% ID/cc, 3h: 0.17+/-0.08% ID/cc, n=9) and [18F]FAZA (1h: 1.95+/-0.59% ID/cc, 3h: 0.87+/-0.55% ID/cc), whereas T/M ratios were significantly higher for [18F]FAZDR at 1h (2.76) compared to [18F]FAZA (1.69, P<0.001), 3h p.i. ratios showed no significant difference. Moreover, [18F]FAZDR showed an inverse correlation between tracer uptake in carcinomas and oxygen breathing, while muscle tissue uptake was not affected by switching from air to oxygen. CONCLUSIONS: First PET imaging results with [18F]FAZDR showed advantages over [18F]FAZA regarding higher tumor contrast at earlier time points p.i. Availability of precursor and cold fluoro standard together with high output radiosynthesis will allow for a more detailed quantitative evaluation of [18F]FAZDR, especially with regard to mechanistic studies whether active transport processes are involved, compared to passive diffusion as observed for [18F]FAZA.

AB - Fluorine-18 labeled fluoronicotinic acid-2,3,5,6-tetrafluorophenyl ester has been successfully synthesized in an unprecedented way by flowing an acetonitrile solution of its quaternary ammonium salt precursor (N,N,N-trimethyl-5-((2,3,5,6 tetrafluorophenoxy)carbonyl)pyridin-2-aminium trifluoromethanesulfonate, 1) through an anion exchange cartridge. The fluorination reaction proceeded at room temperature without azeotropic drying of the fluoride. Over 75% conversion was observed with 10mg of precursor in 2:8, acetonitrile: t-butanol in 1min. The total synthesis time was 5min which is ~30min shorter than the current literature method.

AB - INTRODUCTION: Melanoma is a highly malignant cutaneous tumor of melanin-producing cells. MEL050 is a synthetic benzamide-derived molecule that specifically binds to melanin with high affinity. Our aim was to implement a fully automated radiosynthesis of [18F]MEL050, using for the first time, the AllInOneTM synthesis module (Trasis), and to evaluate the potential of [18F]MEL050 for the detection of pigmented melanoma in mice primary subcutaneous tumors and pulmonary metastases, and to compare it with that of [18F]FDG. METHODS: Automated radiosynthesis of [18F]MEL050, including HPLC purification and formulation, were performed on an AllInOneTM synthesis module. [18F]MEL050 was synthesized using a one-step bromine-for-fluorine nucleophilic heteroaromatic substitution. Melanoma models were induced by subcutaneous (primary tumor) or intravenous (pulmonary metastases) injection of B16-F10-luc2 cells in NMRI mice. The maximum percentage of [18F]MEL050 Injected Dose per g of lung tissue (%ID/g Max) was determined on PET images, compared to [18F]FDG and correlated to in vivo bioluminescence imaging. RESULTS: The automated radiosynthesis of [18F]MEL050 required an overall radiosynthesis time of 48min, with a yield of 13-18% (not-decay corrected) and radiochemical purity higher than 99%. [18F]MEL050 PET/CT images were concordant with bioluminescence imaging, showing increased radiotracer uptake in all primary subcutaneous tumors and pulmonary metastases of mice. PET quantification of radiotracers uptake in tumors and muscles demonstrated similar tumor-to background ratio (TBR) with [18F]MEL050 and [18F]FDG in subcutaneous tumors and higher TBR with [18F]MEL050 than with [18F]FDG in pulmonary metastases. CONCLUSION: We successfully implemented the radiosynthesis of [18F]MEL050 using the AllInOneTM module, including HPLC purification and formulation. In vivo PET/CT validation of [18F]MEL050 was obtained in mouse models of pigmented melanoma, where higher [18F]MEL050 uptake was observed in sub-millimetric pulmonary metastases, comparatively to [18F]FDG.

PMID- 27693676 TI - Correlation among chemical structure, surface properties and cytotoxicity of N acyl alanine and serine surfactants. AB - Toxicity is one of the main concerns limiting the use of surfactants. Many efforts have been devoted to the development of new amphiphilic molecules characterized by a lower toxicological profile and environmental impact. N-acyl amino acids are a class of anionic surfactants that can find applications in different technological fields as an alternative to sulphate-based surfactants (e.g., sodium dodecyl sulphate). The understanding of the relationship between chemical structure and toxicological profile is fundamental for the disclosure of the full potential of these amphiphiles. With this aim, two series of N-acyl surfactants, with different length of the hydrophobic tails and serine or alanine as polar head, were synthesized and fully characterized. The correlation between the surface and toxicological parameters allowed highlighting the role exerted by the length of the hydrocarbon chain and the polar head on cytotoxicity. The length of the hydrocarbon chain mainly influences surface properties and toxicological parameters, while the amino acid polar head may play a key role only on cellular toxicity. Overall, our data suggest that minor differences in the polar head, not significantly affecting CMC values, may have an impact on cytotoxicity. PMID- 27693677 TI - Development, in vitro and in vivo evaluation of a self-emulsifying drug delivery system (SEDDS) for oral enoxaparin administration. AB - AIM: The aim of this study was to develop SEDDS for oral enoxaparin administration and evaluate it in vitro and in vivo. METHODS: The emulsifying properties of SEDDS composed of long chain lipids (LC-SEDDS), medium chain lipids (MC-SEDDS), short chain lipids (SC-SEDDS) and no lipids (NL-SEDDS) were evaluated. Thereafter, enoxaparin was incorporated via hydrophobic ion pairing in the chosen SEDDS, which were evaluated regarding their mucus permeating properties, stability towards pancreatic lipase, drug release profile and cytotoxicity. Finally, in vivo performance of SEDDS was evaluated. RESULTS: The average droplet size of chosen LC-SEDDS, MC-SEDDS and NL-SEDDS ranged between 30 and 40nm. MC-SEEDS containing 30% Captex 8000, 30% Capmul MCM, 30% Cremophor EL and 10% propylene glycol and NL-SEDDS containing 31.5% Labrafil 1944, 22.5% Capmul PG-8, 9% propylene glycol, 27% Cremophor EL and 10% DMSO exhibited 2-fold higher mucus diffusion than LC-SEDDS and were therefore chosen for further studies. The enoxaparin-dodecylamine complex (ENOX/DOA) was incorporated in a payload of 2% (w/w) into MC-SEDDS and NL-SEDDS. After 90min 97% of MC-SEDDS and 5% of NL-SEDDS were degraded by pancreatic lipase. Both MC-SEDDS and NL-SEDDS showed sustained in vitro enoxaparin release. Furthermore, orally administrated MC-SEDDS and NL-SEDDS yielded an absolute enoxaparin bioavailability of 2.02% and 2.25%, respectively. CONCLUSION: According to the abovementioned findings, SEDDS could be considered as a potential oral LMWH delivery system. PMID- 27693678 TI - Gastrointestinal dissolution, supersaturation and precipitation of the weak base indinavir in healthy volunteers. AB - This study investigated the impact of relevant gastrointestinal conditions on the intraluminal dissolution, supersaturation and precipitation behavior of the weakly basic drug indinavir. The influence of (i) concomitant PPI intake and (ii) the nutritional state on the gastrointestinal behavior of indinavir was assessed in order to identify the underlying mechanisms responsible for previously reported interactions. Five healthy volunteers were recruited into a crossover study containing the following arms: fasted state, fed state and fasted state with concomitant proton pump inhibitor (PPI) use. In each condition, one Crixivan(r) capsule (400mg indinavir) was orally administered with 240mL of water. Gastric and duodenal fluids, aspirated as a function of time, were monitored for total and dissolved indinavir concentrations on a UPLC-MS/MS system. Indinavir's thermodynamic solubility was determined in individual aspirates to evaluate supersaturation. The bioaccessible fraction of indinavir in aspirated duodenal fluids was determined in an ex vivo permeation experiment through an artificial membrane. A nearly complete dissolution of indinavir in the fasted stomach was observed (90+/-3%). Regardless of dosing conditions, less indinavir was in solution in the duodenum compared to the stomach. Duodenal supersaturation was observed in all three testing conditions. The highest degrees of duodenal supersaturation (6.5+/-5.9) were observed in the fasted state. Concomitant PPI use resulted in an increased gastric pH and a smaller fraction of indinavir being dissolved (58+/-24%), eventually resulting in lower intestinal concentrations. In fed state conditions, drug release from the capsule was delayed and more gradually, although a similar fraction of the intragastric indinavir dissolved compared to the fasted state (83+/-12%). Indinavir was still present in the lumen of the duodenum three hours after oral administration, although it already reached 70% (on average) of the fasted state concentrations (expressed as AUC0-3h). Based on a 2-h permeation experiment, the bioaccessible fraction of indinavir was 2.6-fold lower in a fed state sample compared to a fasted state sample. Our data indicate that the reported reduction in indinavir's bioavailability after concomitant PPI administration is caused by an elevated gastric pH resulting in less indinavir in solution in the stomach and, subsequently, reduced duodenal concentrations. In fed state conditions, however, intestinal micellar entrapment of indinavir appeared to cause the reported reduced bioavailability, regardless of duodenal concentrations. PMID- 27693679 TI - Zinc peroxide nanomaterial as an adsorbent for removal of Congo red dye from waste water. AB - In the past decade, various natural byproducts, advanced metal oxide composites and photocatalysts have been reported for removal of dyes from water. Although these materials are useful for select applications, they have some limitations such as use at fixed temperature, ultra violet (UV) light and the need for sophisticated experimental set up. These materials can remove dyes up to a certain extent but require long time. To overcome these limitations, a promising adsorbent zinc peroxide (ZnO2) nanomaterial has been developed for the removal of Congo red (CR) dye from contaminated water. ZnO2 is highly efficient even in the absence of sunlight to remove CR from contaminated water upto the permissible limits set by the World Health Organization (WHO) and the United States- Environmental Protection Agency (US-EPA). The adsorbent has a specific property to adjust the pH of the test solution within 6.5-7.5 range irrespective of acidic or basic nature of water. The adsorption capacity of the material for CR dye was 208mgg-1 within 10min at 2-10pH range. The proposed material could be useful for the industries involved in water purification. The removal of CR has been confirmed by spectroscopic and microscopic techniques. The adsorption data followed a second order kinetics and Freundlich isotherm.

A Survey of Symptoms and Injuries in Oncologic Surgeons and Pilot Study of an Intraoperative Ergonomic Intervention. AB - BACKGROUND: Occupational symptoms and injuries incurred over a surgical career are under- reported, yet they have an impact on daily surgical practice. We assessed the frequency, consequences, and risk factors for occupational injury in oncologic surgeons and evaluated the feasibility of intraoperative foot mat use to mitigate occupational symptoms. STUDY DESIGN: Oncologic surgeons completed a survey of demographic information and occupational symptoms and injuries. Multivariate logistic regression was used to identify factors associated with occupational symptoms and injuries. A randomized cross-over pilot study of intraoperative foot mat use was conducted. RESULTS: One hundred twenty-seven surgeons completed surveys (response rate: 58%). The most commonly reported symptoms were fatigue, discomfort, stiffness, and back pain. An occupational injury was reported by 27.6% of surgeons. Of those injured, 65.7% received treatment, with 17.4% of those treated requiring surgery for their injury. In multivariate analysis, factors significantly associated with occupational injury were male sex (odds ratio [OR] 3.00, 95% CI 1.08 to 8.38), mean case length of 4 hours or more (OR 2.72, 95% CI 1.08 to 6.87), using a step to operate (OR 3.06, 95% CI 1.02 to 9.15), and neck pain (OR 4.81, 95% CI 1.64 to 14.12). In the foot mat pilot study (n = 20), mat use was associated with discomfort (OR 7.57, 95% CI 1.19 to 48.00), but no significant differences in leg volume change due to mat use were found. CONCLUSIONS: Most oncologic surgeons experience musculoskeletal symptoms from operating. Of the 28% of surgeons with an occupational injury, most required treatment. Intraoperative foot mat use was associated with increased discomfort. PMID- 27693680 TI - Cadmium stress tolerance in wheat seedlings induced by ascorbic acid was mediated by NO signaling pathways. AB - Ascorbic acid (AsA) and nitric oxide (NO) are well known and widespread antioxidants and gaseous molecules that regulate plant tolerance to several stresses. However, the relationship between them in plant response to stress, especially heavy stress, is largely unclear. This study demonstrated that both AsA and NO could enhance the tolerance of wheat seedlings to cadmium stress evidenced by root length change, which resulted from their roles in maintaining the balance in reactive oxygen species (ROS) and reducing the absorption of Cd. Furthermore, exogenous AsA led to a significant increase of NO content and endogenous AsA content in wheat roots, which could be weakened by the NO scavenger c-PTIO. In addition, c-PTIO also inhibits the NO-induced production of endogenous AsA. Although the AsA synthesis inhibitor lycorine significantly inhibited the inductive effect of exogenous AsA on endogenous AsA production, it has little effect on NO content. In addition, we found that the protective effects of NO and AsA on Cd stress were removed by c-PTIO and lycorine. These results indicated that NO accumulation could be necessary for exogenous AsA induced cadmium tolerance and endogenous AsA production, and the exogenous AsA induced endogenous AsA production was likely mediated by NO signaling pathways and together they induced the tolerance of wheat to cadmium stress.

AB - The aim of this study was to find an objective estimate of individual, complete loudness growth functions based on auditory steady-state responses. Both normal hearing and hearing-impaired listeners were involved in two behavioral loudness growth tasks and one EEG recording session. Behavioral loudness growth was measured with Absolute Magnitude Estimation and a Graphic Rating Scale with loudness categories. Stimuli were sinusoidally amplitude-modulated sinusoids with carrier frequencies of either 500 Hz or 2000 Hz, a modulation frequency of 40 Hz, a duration of 1 s, and presented at intensities encompassing the participants' dynamic ranges. Auditory steady-state responses were evoked by the same stimuli using durations of at least 5 min. Results showed that there was a good correspondence between the relative growth of the auditory steady-state response amplitudes and the behavioral loudness growth responses for each participant of both groups of listeners. This demonstrates the potential for a more individual, objective, and automatic fitting of hearing aids in future clinical practice. PMID- 27693685 TI - The granulocytes are the main immunocompetent hemocytes in Crassostrea gigas. AB - Hemocytes comprise diverse cell types with morphological and functional heterogeneity and play indispensable roles in immunological homeostasis of invertebrates. The morphological classification of different hemocytes in mollusk has been studied since the 1970's, yet the involvement of the different sub populations in immune functions is far from clear. In the present study, three types of hemocytes were morphologically identified and separated as agranulocytes, semi-granulocytes and granulocytes by flow cytometry and Percoll(r) density gradient centrifugation. The granulocytes were characterized functionally as the main phagocytic and encapsulating population, while semi granulocytes and agranulocytes exhibited low or no such capacities, respectively. Meanwhile, the lysosome activity and the productions of ROS and NO were all mainly concentrated in granulocytes under both normal and immune-activated situations. Further, the mRNA transcripts of some immune related genes, including CgTLR, CgClathrin, CgATPeV, CgLysozyme, CgDefensin and CgIL-17, were mainly expressed in granulocytes, lower in semi-granulocytes and agranulocytes. These results collectively suggested that the granulocytes were the main immunocompetent hemocytes in oyster C. gigas, and a differentiation relationship among these three sub-population hemocytes was inferred based on the gradual changes in morphological, functional and molecular features. PMID- 27693686 TI - Gold-nanoparticles coated with the antimicrobial peptide esculentin-1a(1-21)NH2 as a reliable strategy for antipseudomonal drugs. AB - : Naturally occurring antimicrobial peptides (AMPs) hold promise as future therapeutics against multidrug resistant microorganisms. Recently, we have discovered that a derivative of the frog skin AMP esculentin-1a, Esc(1-21), is highly potent against both free living and biofilm forms of the bacterial pathogen Pseudomonas aeruginosa. However, bringing AMPs into clinics requires to overcome their low stability, high toxicity and inefficient delivery to the target site at high concentrations. Importantly, peptide conjugation to gold nanoparticles (AuNPs), which are among the most applied inorganic nanocarriers in biomedical sciences, represents a valuable strategy to solve these problems. Here we report that covalent conjugation of Esc(1-21) to soluble AuNPs [AuNPs@Esc(1 21)] via a poly(ethylene glycol) linker increased by ~15-fold the activity of the free peptide against the motile and sessile forms of P. aeruginosa without being toxic to human keratinocytes. Furthermore, AuNPs@Esc(1-21) resulted to be significantly more resistant to proteolytic digestion and to disintegrate the bacterial membrane at very low concentration (5nM). Finally, we demonstrated for the first time the capability of peptide-coated AuNPs to display a wound healing activity on a keratinocytes monolayer. Overall, these findings suggest that our engineered AuNPs can serve as attractive novel biological-derived material for topical treatment of epithelial infections and healing of the injured tissue. STATEMENT OF SIGNIFICANCE: Despite conjugation of AMPs to AuNPs represents a worthwhile solution to face some limitations for their development as new therapeutics, only a very limited number of studies is available on peptide coated AuNPs. Importantly, this is the first report showing that a covalent binding of a linear AMP via a poly(ethylene glycol) linker to AuNPs highly enhances antipseudomonal activity, preserving the same mode of action of the free peptide, without being harmful. Furthermore, AuNPs@Esc(1-21) are expected to accelerate recovery of an injured skin layer. All together, these findings suggest our peptide-coated AuNPs as attractive novel nanoscale formulation to treat bacterial infections and to heal the injured tissue.

AB - : Silkworm cocoon material is a natural composite consisting of silk fibres and sericin glues. Both domestic and wild silkworms produce cocoons but with different functionality - one selected by man for textile manufacture whereas the other selected by Nature to provide damage-tolerant housing. To understand the structure--property relationship of cocoons, we evaluated and compared the microstructure and mechanical properties of two representative cocoon walls. It appears that a "brittle and weak" composite is produced by domestic Bombyx mori (B. mori) while a "tough and strong" composite is made by wild Antheraea pernyi (A. pernyi). The superior mechanical performance of A. pernyi cocoons can be attributed to both the material properties and the fibre network microstructures. Failure mechanisms and different failure modes for cocoon fibre composites were also proposed. A finite element model revealed qualitatively the effect of fibre properties and inter-fibre bonding strength on the mechanical properties of the fibre network. It emerged that both good mechanical properties of fibres and robust inter-fibre bonding were required for tough and strong fibre composites. The new insights could inspire new designs of synthetic fibre composites with enhanced mechanical properties. STATEMENT OF SIGNIFICANCE: Natural cocoons are an important group of natural fibre composites with versatile functionalities. Previous studies have focused on the diversity of cocoon species and different morphological and mechanical features. It was suggested that the cocoon network structure determined the final mechanical properties of the cocoon composite. Nevertheless, the full structure-propertyfunction relationships for the cocoon composite are not understood. By studying two distinct cocoon species with specific functionalities, we prove that the mechanical properties of two cocoons are determined by both network properties and fibre properties. A robust fibre network is the prerequisite, within which the good mechanical properties of the fibres can play a part. The finding will inspire new designs of synthetic composites with desirable and predictable mechanical properties. PMID- 27693688 TI - Modular peptides from the thermoplastic squid sucker ring teeth form amyloid-like cross-beta supramolecular networks. AB - : The hard sucker ring teeth (SRT) from decapodiforme cephalopods, which are located inside the sucker cups lining the arms and tentacles of these species, have recently emerged as a unique model structure for biomimetic structural biopolymers. SRT are entirely composed of modular, block co-polymer-like proteins that self-assemble into a large supramolecular network. In order to unveil the molecular principles behind SRT's self-assembly and robustness, we describe a combinatorial screening assay that maps the molecular-scale interactions between the most abundant modular peptide blocks of suckerin proteins. By selecting prominent interaction hotspots from this assay, we identified four peptides that exhibited the strongest homo-peptidic interactions, and conducted further in depth biophysical characterizations complemented by molecular dynamic (MD) simulations to investigate the nature of these interactions. Circular Dichroism (CD) revealed conformations that transitioned from semi-extended poly-proline II (PII) towards beta-sheet structure. The peptides spontaneously self-assembled into microfibers enriched with cross beta-structures, as evidenced by Fourier Transform Infrared Spectroscopy (FTIR) and Congo red staining. Nuclear Magnetic Resonance (NMR) experiments identified the residues involved in the hydrogen bonded network and demonstrated that these self-assembled beta-sheet-based fibers exhibit high protection factors that bear resemblance to amyloids. The high stability of the beta-sheet network and an amyloid-like model of fibril assembly were supported by MD simulations. The work sheds light on how Nature has evolved modular sequence design for the self-assembly of mechanically robust functional materials, and expands our biomolecular toolkit to prepare load-bearing biomaterials from protein-based block co-polymers and self-assembled peptides. STATEMENT OF SIGNIFICANCE: The sucker ring teeth (SRT) located on the arms and tentacles of cephalopods represent as a very promising protein-based biopolymer with the potential to rival silk in biomedical and engineering applications. SRT are made of modular, block co-polymer like proteins (suckerins), which assemble into a semicrystalline polymer reinforced by nano-confined beta-sheets, resulting in a supramolecular network with mechanical properties that match those of the strongest engineering polymers. In this study, we aimed to understand the molecular mechanisms behind SRT's self-assembly and robustness. The most abundant modular peptidic blocks of suckerin proteins were studied by various spectroscopic methods, which demonstrate that SRT peptides form amyloid-like cross-beta structures. PMID- 27693689 TI - Development of multifunctional films for peripheral nerve regeneration. AB - : In this study, a poly(lactic acid) (PLLA) porous film with longitudinal surface micropatterns was fabricated by a dry phase inversion technique to be used as potential conduit material for peripheral nerve regeneration applications. The presence of a nerve growth factor (NGF) gradient on the patterned film surface and protein loaded, surface-eroding, biodegradable, and amphiphilic polyanhydride (PA) microparticles within the film matrix, enabled co-delivery of neurotrophic factors with controlled release properties and enhanced neurite outgrowth from PC12 cells. The protein loading capacity of PA particles was increased up to 80% using the spray drying technique, while the surface loading of NGF reached 300ng/cm2 through ester-amine interactions. The NGF surface gradient provided initial fast release from the film surface and facilitated directional neurite outgrowth along with the longitudinal micropatterns. Furthermore, the variable backbone chemistry and surface eroding nature of protein-loaded PA microparticles within the film matrix ensured protein stability and enabled controlled protein release. This novel co-delivery strategy yielded tunable diffusion coefficients varying between 6*10-14 and 1.67*10-10cm2/min and dissolution constants ranging from 1*10-4 to 1*10-3min-1 with released amounts of ~100-300ng/mL. This strategy promoted guided neurite extension from PC12 cells of up to 10MUm total neurite length per cell in 2days. Overall, this unique strategy can potentially be extended for individually programmed delivery of multiple growth factors through the use of PA microparticle cocktails and can further be investigated for in vivo performance as potential conduit material for peripheral nerve regeneration applications. STATEMENT OF SIGNIFICANCE: This manuscript focuses on the development of multifunctional degradable polymer films that provide topographic cues for guided growth, surface gradients of growth factors as well as nanoparticles in the films for tunable release of growth factors to enable peripheral nerve regeneration. The combination of cues was designed to overcome limitations of current strategies to facilitate peripheral nerve regeneration. These multifunctional films successfully provided high protein loading capacities while persevering activity, protein gradients on the surface, and tunable release of bioactive nerve growth factor that promoted directional and guided neurite extension of PC12 cells of up to 10MUm in 2days. These multifunctional films can be made into conduits for peripheral nerve regeneration. PMID- 27693691 TI - Muscle Activation During Pilates Exercises in Participants With Chronic Nonspecific Low Back Pain: A Cross-Sectional Case-Control Study. AB - OBJECTIVE: To determine the amplitude of the electromyographic activity of trunk muscles during Pilates exercises in women with and without chronic low back pain (LBP). DESIGN: Case-control study. SETTING: University physical therapy clinic. PARTICIPANTS: Women (N=60) divided into an LBP group and a control group. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Amplitude of the electromyographic activity (root mean square values) of the gluteus maximus and external oblique muscles collected during 3 Pilates exercises: Shoulder Bridge performed on the mat, and Hip Roll and Breathing performed in equipment. Pain intensity was assessed in the LBP group. RESULTS: The amplitude of the electromyographic activity was similar between groups (P>=.05). For both groups, the amplitude of the gluteus maximus was higher in the Shoulder Bridge exercise compared with the Hip Roll with 2 springs (control group: mean difference [MD]=.18; 95% confidence interval [CI], .05-.41; LBP group: MD=.29; 95% CI, .16 .31) and the Breathing exercise (control group: MD=-.40; 95% CI, -.55 to -.26; LBP group: MD=-.36; 95% CI, -.52 to -.20). The amplitude of the external oblique muscle was higher in the Shoulder Bridge compared with the Hip Roll with 2 springs (control group: MD=.13; 95% CI, .05-.21; LBP group: MD=.18; 95% CI, .03 .33). Pain intensity increased after exercises, but this increase was lower for the mat exercises. CONCLUSIONS: Similar muscle activation between groups was found. The findings suggest that mat exercises caused less pain and a greater difference in the amplitude of muscle activation compared with the equipment based exercises. PMID- 27693690 TI - Targeted proteomics effectively quantifies differences between native lung and detergent-decellularized lung extracellular matrices. AB - : Extracellular matrix is a key component of many products in regenerative medicine. Multiple regenerative medicine products currently in the clinic are comprised of human or xenogeneic extracellular matrix. In addition, whole-organ regeneration exploits decellularized native organs as scaffolds for organotypic cell culture. However, precise understanding of the constituents of such extracellular matrix-based implants and scaffolds has sorely lagged behind their use. We present here an advanced protein extraction method using known quantities of proteotypic 13C-labeled peptides to quantify matrix proteins in native and decellularized lung tissues. Using quantitative proteomics that produce picomole level measurements of a large number of matrix proteins, we show that a mild decellularization technique ("Triton/SDC") results in near-native retention of laminins, proteoglycans, and other basement membrane and ECM-associated proteins. Retention of these biologically important glycoproteins and proteoglycans is quantified to be up to 27-fold higher in gently-decellularized lung scaffolds compared to scaffolds generated using a previously published decellularization regimen. Cells seeded onto this new decellularized matrix also proliferate robustly, showing positive staining for proliferating cell nuclear antigen (PCNA). The high fidelity of the gently decellularized scaffold as compared to the original lung extracellular matrix represents an important step forward in the ultimate recapitulation of whole organs using tissue-engineering techniques. This method of ECM and scaffold protein analysis allows for better understanding, and ultimately quality control, of matrices that are used for tissue engineering and human implantation. These results should advance regenerative medicine in general, and whole organ regeneration in particular. STATEMENT OF SIGNIFICANCE: The extracellular matrix (ECM) in large part defines the biochemical and mechanical properties of tissues and organs; these inherent cues make acellular ECM scaffolds potent substrates for tissue regeneration. As such, they are increasingly prevalent in the clinic and the laboratory. However, the exact composition of these scaffolds has been difficult to ascertain. This paper uses targeted proteomics to definitively quantify 71 proteins present in acellular lung ECM scaffolds. We use this technique to compare two decellularization methods and demonstrate superior retention of ECM proteins important for cell adhesion, migration, proliferation, and differentiation in scaffolds treated with low-concentration detergent solutions. In the long term, the ability to acquire quantitative biochemical data about biological substrates will facilitate the rational design of engineered tissues and organs based on precise cell-matrix interactions. PMID- 27693692 TI - 5-Aminolevulinic acid with sodium ferrous citrate induces autophagy and protects cardiomyocytes from hypoxia-induced cellular injury through MAPK-Nrf-2-HO-1 signaling cascade. AB - BACKGROUND: Hypoxia causes cardiac disease via oxidative stress and mitochondrial dysfunction. 5-Aminolevulinic acid in combination with sodium ferrous citrate (ALA/SFC) has been shown to up-regulate heme oxygenase-1 (HO-1) and decrease macrophage infiltration and renal cell apoptosis in renal ischemia injury mice. However, its underlying mechanism remains largely unknown. The aim of this study was to investigate whether ALA/SFC could protect cardiomyocytes from hypoxia induced apoptosis by autophagy via HO-1 signaling. MATERIALS & METHODS: Murine atrial cardiomyocyte HL-1 cells were pretreated with ALA/SFC and then exposed to hypoxia. RESULTS: ALA/SFC pretreatment significantly attenuated hypoxia-induced cardiomyocyte apoptosis, reactive oxygen species production, and mitochondrial injury, while it increased cell viability and autophagy levels. HO-1 expression by ALA/SFC was associated with up-regulation and nuclear translocation of Nrf-2, whereas Nrf-2 siRNA dramatically reduced HO-1 expression. ERK1/2, p38, and SAPK/JNK pathways were activated by ALA/SFC and their specific inhibitors significantly reduced ALA/SFC-mediated HO-1 upregulation. Silencing of either Nrf 2 or HO-1and LY294002, inhibitor of autophagy, abolished the protective ability of ALA/AFC against hypoxia-induced injury and reduced ALA/SFC-induced autophagy. CONCLUSION: Taken together, our data suggest that ALA/SFC induces autophagy via activation of MAPK/Nrf-2/HO-1 signaling pathway to protect cardiomyocytes from hypoxia-induced apoptosis. PMID- 27693693 TI - Lumican alleviates hypertrophic scarring by suppressing integrin-FAK signaling. AB - Hypertrophic scarring (HS) is an overcompensation of wound healing that increases the risk of cosmetic disfigurement and functional impairment. No gold standard has been established for the treatment or prevention of HS. Our study aims to elucidate the expression and function of lumican in the pathogenesis of HS as well as the underlying mechanism involved in this procedure. An animal model of HS (rabbit ear) was established, and the Ad-lumican vectors were locally injected. Primary fibroblasts isolated from patients with hypertrophic burn scars were used in vitro. Histological and molecular changes in HS pathogenesis were evaluated. The results showed that lumican is significantly reduced in HS tissues and fibroblasts from HS patients as compared to normal skin or cells. Lumican levels were further suppressed in response to TGF-beta stimulation. However, lumican upregulation effectively thinned the scar area and inhibited fibroblast proliferation and the cell cycle. Meanwhile, Ad-lumican administration suppressed the deposition of extracellular matrix, such as collagen and CTGF. Ad-lumican injected animals or fibroblasts presented comparable integrin alpha2beta1 expression while greatly reduced phosphorylation of FAK compared to the negative control. Moreover, Ad-lumican administration largely enhanced the binding of lumican to integrin alpha2beta1 and may thus inhibit the signaling propagation of collagen-integrin alpha2beta1. Overall, the restoration of lumican levels contributed to suppressing the HS progression by inhibiting collagen-integrin alpha2beta1-FAK signaling. PMID- 27693694 TI - Progressive hearing loss and degeneration of hair cell stereocilia in taperin gene knockout mice. AB - The TPRN gene encodes taperin, which is prominently present at the taper region of hair cell stereocilia. Mutations in TPRN have been reported to cause autosomal recessive nonsyndromic deafness 79(DFNB 79). To investigate the role of taperin in pathogenesis of hearing loss, we generated TPRN knockout mice using TALEN technique. Sanger sequencing confirmed an 11 bp deletion at nucleotide 177-187 in exon 1 of TPRN, which results in a truncated form of taperin protein. Heterozygous TPRN+/- mice showed apparently normal auditory phenotypes to their wide-type (WT) littermates. Homozygous TPRN-/- mice exhibited progressive sensorineural hearing loss as reflected by auditory brainstem response to both click and tone burst stimuli at postnatal days 15 (P15), 30 (P30), and 60 (P60). Alex Fluor-594 phalloidin labeling showed no obvious difference in hair cell numbers in the cochlea between TPRN-/- mice and WT mice under light microscope. However, scanning electronic microscopy revealed progressive degeneration of inner hair cell stereocilia, from apparently normal at postnatal days 3 (P3) to scattered absence at P15 and further to substantial loss at P30. The outer hair cell stereocilia also showed progressive degeneration, though much less severe, Collectively, we conclude that taperin plays an important role in maintenance of hair cell stereocilia. Establishment of TPRN knockout mice enables further investigation into the function of this gene. PMID- 27693695 TI - Blocking CXCR7-mediated adipose tissue macrophages chemotaxis attenuates insulin resistance and inflammation in obesity. AB - Adipose tissue macrophages (ATMs) have been considered to have a pivotal role in the chronic inflammation development during obesity. Although chemokine-chemokine receptor interaction has been studied in ATMs infiltration, most chemokine receptors remain incompletely understood and little is known about their mechanism of actions that lead to ATMs chemotaxis and pathogenesis of insulin resistance during obesity. In this study, we reported that CXCR7 expression is upregulated in adipose tissue, and specifically in ATMs during obesity. In addition, CXCL11 or CXCL12-induced ATMs chemotaxis is mediated by CXCR7 in obesity but not leanness, whereas CXCR3 and CXCR4 are not involved. Additional mechanism study shows that NF-kappaB activation is essential in ATMs chemotaxis, and manipulates chemotaxis of ATMs via CXCR7 expression regulation in obesity. Most importantly, CXCR7 neutralizing therapy dose dependently leads to less infiltration of macrophages into adipose tissue and thus reduces inflammation and improves insulin sensitivity in obesity. In conclusion, these findings demonstrated that blocking CXCR7-mediated ATMs chemotaxis ameliorates insulin resistance and inflammation in obesity. PMID- 27693696 TI - NLRP2 is highly expressed in a mouse model of ischemic stroke. AB - Nucleotide binding oligomerization domain (NOD)-like receptors (NLRs) are a class of cytoplasmic pattern-recognition receptors with a major role in innate immunity. Fourteen of the twenty-two human NLRs contain a pyrin domain and form the NLRP subfamily (NLRPs). Among NLRPs, NLRP2 is less well-understood in aspects of distribution and functions, especially in central nervous system (CNS). This study was the first to explore the expression of NLRP2 in central nervous system both under normal conditions and in ischemic stroke models. We found NLRP2 protein had a basal level of expression in CNS, mainly in astrocytes and was significantly elevated in ischemic brains in vivo or oxygen-glucose deprivation treated cells in vitro. And silencing of NLRP2 genes could reduce the apoptotic rate of oxygen-glucose deprivation-treated cells. Thus high expression of NLRP2, especially in astrocytes, may play important roles in the pathophysiological process of ischemic stroke and has potential clinical value for the treatment of ischemic stroke. PMID- 27693697 TI - Let-7d miRNA prevents TGF-beta1-induced EMT and renal fibrogenesis through regulation of HMGA2 expression. AB - TGF-beta1-induced epithelial to mesenchymal transition (EMT) process of tubular epithelial cells plays a leading role in the occurrence and progression of renal fibrosis as seen in diabetic nephropathy (DN). High mobility group AT-hook 2 (HMGA2) is considered to be involved in TGF-beta1-mediated EMT via multifactorial mechanisms. Specific microRNAs (miRNAs) are closely associated with EMT, and here we focused on let-7d miRNA as a regulator of HMGA2. This study aims to investigate the effects of HMGA2 on EMT process induced by TGF-beta1 using small interfering RNA (siRNA) technique in vitro, and further explore the potential role of let-7d miRNA during renal fibrosis in DN. We demonstrated that siRNA targeting HMGA2 was sufficient to inhibit TGF-beta1-induced EMT and fibrogenesis in rat kidney tubular epithelial cells (NRK52E). Furthermore, let-7d expression was significantly reduced by TGF-beta1 stimulation, we focused on let-7d and found that overexpression of let-7d down-regulated the expression of HMGA2 and in turn suppressed TGF-beta1-induced EMT and renal fibrogenesis. Inhibition of let 7d increased HMGA2 expression and enhanced the profibrogenic effects of TGF-beta1 on NRK-52E cells. Consistent with the above observations in vitro, let-7d expression was also decreased in the kidneys of unilateral ureter obstruction model, accompanied by the correspondingly increased expression of HMGA2 and fibrotic genes in this model. Collectively, HMGA2 and let-7d miRNA significantly impact on the progression of TGF-beta1-induced EMT and fibrogenesis both in vitro and in vivo, and they may represent novel targets for the prevention strategies of renal fibrosis in the context of DN. PMID- 27693698 TI - Identification of a new sweat gland progenitor population in mice and the role of their niche in tissue development. AB - Sweat gland cells are responsible for the regulation of body temperature and are critical for wound repair. Furthermore, they have the regenerative potential in response to injury, and show a substantial turnover during both wound healing and homeostasis. However, as a usual research model of sweat gland, mice have not too much glandular cells for experiments. In this study, we identify previously unreported sweat gland progenitor population in mice and characterize them. The progenitor characteristics of sweat gland were confirmed using cellular immunofluorescence assay and quantitative real-time PCR assay. K8 and K18 expression was barely detected in the early stage of skin development (Embryo 17.5d) and increased to a high level at P5d (postnatal 5d), then showed reduction at adult stage (P28d). Further investigation of K8 and K18 positive cells using tissue immunofluorescence revealed the presence of sweat gland progenitors in back epidermis of mice at early stage of sweat gland development and continuous reduction during the developmental process. In vivo transplantation assay with animal models elucidated that sweat gland specific niche in paw pads was critical for the development of sweat gland cells. Although the relationship between new sweat gland progenitors and their niche still needs to be further investigated, the presence of these cells implicates that there is more source ascribed to sweat glands in addition to serving as progenitors in mice. PMID- 27693699 TI - The neurocircuitry of remote cued fear memory. AB - Memories of threatening, fear-evoking events can persist even over a lifetime. While fear memory is widely considered to be a highly persistent and durable form of memory, its circuits are not. This article reviews the dynamic temporal representation of remote fear memory in the brain, at the level of local circuits and distributed networks. Data from the study of Pavlovian cued fear conditioning suggests memory retrieval remains amygdala-dependent, even over protracted time scales, all the while interconnected cortical and subcortical circuits are newly recruited and progressively reorganized. A deeper understanding into how the neurocircuitry of cued fear memory reorganizes with the passage of time will advance our ongoing search for the elusive physical changes representing fear memories in the brain. Considering that persistent, pathological fear memories are a hallmark feature of post-traumatic stress disorder (PTSD), the behavioral and circuit-level study of remote cued fear memory retrieval adds a key element towards a systems understanding of PTSD. PMID- 27693700 TI - Understanding heterogeneity in conduct disorder: A review of psychophysiological studies. AB - The present review is concerned with the role of different physiological systems (e.g., skin conductance, heart rate, electromyography, and the eye-bling startle reflex) in understanding heterogeneity in conduct disorder (CD). Four subtyping approaches are considered: age of onset, comorbid psychopathology, callous unemotional traits, and proactive/reactive aggression. Empirical findings are discussed in terms of distinct theoretical perspectives that aim to explain CD behaviors based on physiological over-arousal, under-arousal, and empathy deficits. According to the studies reviewed, the callous-unemotional (CD+CU) and internalizing (CD+Internalizing) sub-types can best inform CD heterogeneity. Findings indicated that children in the CD+CU and CD+Internalizing subtypes score on opposite extremes on heart rate, skin conductance and startle reactivity measures. Heart rate variability and respiratory sinus arrhythmia dysfunctions, associated with emotional dysregulation, were more evident among children in the CD+Internalizing group, while dysfunctional facial electromyography activity, which has been linked with reduced empathy, with the CD+CU group. In conclusion, it might be important to redefine CD diagnostic criteria based on physiological heterogeneity to enable the identification of distinct subtypes of CD. PMID- 27693701 TI - Category and design fluency in mild cognitive impairment: Performance, strategy use, and neural correlates. AB - The exploration and retrieval of words during category fluency involves different strategies to improve or maintain performance. Deficits in that task, which are common in patients with amnestic mild cognitive impairment (aMCI), mirror either impaired semantic memory or dysfunctional executive control mechanisms. Relating category fluency to tasks that place greater demands on either semantic knowledge or executive functions might help to determine the underlying cognitive process. The aims of this study were to compare performance and strategy use of 20 patients with aMCI to 30 healthy elderly controls (HC) and to identify the dominant component (either executive or semantic) for better task performance in category fluency. Thus, the relationship between category fluency, design fluency and naming was examined. As fluency tasks have been associated with the superior frontal gyrus (SFG), the inferior frontal gyrus (IFG), and the temporal pole, we further explored the relationship between gray matter volume in these areas and both performance and strategy use. Patients with aMCI showed significantly lower performance and significantly less strategy use during fluency tasks compared to HC. However, both groups equally improved their performance when repeatedly confronted with the same task. In aMCI, performance during category fluency was significantly predicted by design fluency performance, while in HC, it was significantly predicted by naming performance. In HC, volume of the SFG significantly predicted both category and design fluency performance, and strategy use during design fluency. In aMCI, the SFG and the IFG predicted performance during both category and design fluency. The IFG significantly predicted strategy use during category fluency in both groups. The reduced category fluency performance in aMCI seems to be primarily due to dysfunctional executive control mechanisms rather than impaired semantic knowledge. This finding is directly relevant to patients in the different stages of Alzheimer's disease as it links the known semantic fluency deficit in this population to executive functions. Although patients with aMCI are impaired in both performance and strategy use compared to HC, they are able to increase performance over time. However, only HC were able to significantly improve the utilization of fluency strategies in both category and design fluency over time. HC seem to rely more heavily on the SFG during fluency tasks, while in patients with aMCI additional frontal brain areas are involved, possibly reflecting compensational processes. PMID- 27693703 TI - Nitric oxide-releasing chitosan nanoparticles alleviate the effects of salt stress in maize plants. AB - Nitric oxide (NO) is a signaling molecule involved in plant response to various abiotic stresses. However, the application of NO donors in agriculture is hampered by the instability of these compounds. Despite the successful uses of NO releasing nanoparticles for biomedical purposes and the variety of nanomaterials developed as carrier systems of agrochemicals, the potential applications of nanocarriers for NO delivery in plants have not yet been tested. Herein, we report the synthesis and characterization of chitosan nanoparticles (CS NPs) containing the NO donor S-nitroso-mercaptosuccinic acid (S-nitroso-MSA). The efficiency of these NO-releasing NPs in mitigating the deleterious effects of salinity on maize plants was compared to that of the non-encapsulated NO donor. The NPs were synthesized through ionotropic gelation process, and mercaptosuccinic acid (MSA), the NO donor precursor, was encapsulated into CS NPs (91.07% encapsulation efficiency). Free thiol groups of MSA-CS NPs were nitrosated, leading to S-nitroso-MSA-CS NPs (NO-releasing NPs). The incorporation of S-nitroso-MSA into CS NPs allowed a sustained NO release. Treatments of salt stressed maize plants with S-nitroso-MSA-CS NPs resulted in a higher leaf S nitrosothiols content compared to that of free S-nitroso-MSA. Moreover, S-nitroso MSA-CS NPs were more efficient than was the free NO donor in the amelioration of the deleterious effects of salinity in photosystem II activity, chlorophyll content and growth of maize plants because the protective action of the nanoencapsulated S-nitroso-MSA was achieved at lower dosages. Overall, these results demonstrate the positive impact of S-nitroso-MSA nanoencapsulation in increasing NO bioactivity in maize plants under salt stress. PMID- 27693702 TI - A single trial analysis of EEG in recognition memory: Tracking the neural correlates of memory strength. AB - Recent work in perceptual decision-making has shown that although two distinct neural components differentiate experimental conditions (e.g., did you see a face or a car), only one tracked the evidence guiding the decision process. In the memory literature, there is a distinction between a fronto-central evoked potential measured with EEG beginning at 350ms that seems to track familiarity and a late parietal evoked potential that peaks at 600ms that tracks recollection. Here, we applied single-trial regressor analysis (similar to multivariate pattern analysis, MVPA) and diffusion decision modeling to EEG and behavioral data from two recognition memory experiments to test whether these two components contribute to the recognition decision process. The regressor analysis only involved whether an item was studied or not and did not involve any use of the behavioral data. Only late EEG activity distinguishes studied from not studied items that peaks at about 600ms following each test item onset predicted the diffusion model drift rate derived from the behavioral choice and reaction times (but only for studied items). When drift rate was made a linear function of the trial-level regressor values, the estimate for studied items was different than zero. This showed that the later EEG activity indexed the trial-to-trial variability in drift rate for studied items. Our results provide strong evidence that only a single EEG component reflects evidence being used in the recegnition decision process. PMID- 27693704 TI - Astaxanthin enhances pemetrexed-induced cytotoxicity by downregulation of thymidylate synthase expression in human lung cancer cells. AB - Pemetrexed, a multitargeted antifolate agent, has demonstrated clinical activity in non-small cell lung cancer (NSCLC) cells. Increased expression of thymidylate synthase (TS) is thought to be associated with resistance to pemetrexed. Astaxanthin exhibits a wide range of beneficial effects including anti-cancer and anti-inflammatory properties. In this study, we showed that down-regulating of TS expression in two NSCLC cell lines, human lung adenocarcinoma H1650 and squamous cell carcinoma H1703 cells, with astaxanthin were associated with decreased MKK1/2-ERK1/2 activity. Enforced expression of constitutively active MKK1 (MKK1 CA) vector significantly rescued the decreased TS mRNA and protein levels in astaxanthin-treated NSCLC cells. Combined treatment with a MKK1/2 inhibitor (U0126 or PD98059) further decreased the TS expression in astaxanthin-exposed NSCLC cells. Knockdown of TS using small interfering RNA (siRNA) or inhibiting ERK1/2 activity enhanced the cytotoxicity and cell growth inhibition of astaxanthin. Combination of pemetrexed and astaxanthin resulted in synergistic enhancing cytotoxicity and cell growth inhibition in NSCLC cells, accompanied with reduced activation of phospho-MKK1/2, phopho-ERK1/2, and TS expression. Overexpression of MKK1/2-CA reversed the astaxanthin and pemetrexed-induced synergistic cytotoxicity. Our findings suggested that the down-regulation of MKK1/2-ERK1/2-mediated TS expression by astaxanthin is an important regulator of enhancing the pemetrexed-induced cytotoxicity in NSCLC cells. PMID- 27693705 TI - Derivation of biomonitoring equivalent for inorganic tin for interpreting population-level urinary biomonitoring data. AB - Population-level biomonitoring of tin in urine has been conducted by the U.S. National Health and Nutrition Examination Survey (NHANES) and the National Nutrition and Health Study (ENNS - Etude nationale nutrition sante) in France. The general population is predominantly exposed to inorganic tin from the consumption of canned food and beverages. The National Institute for Public Health and the Environment of the Netherlands (RIVM) has established a tolerable daily intake (TDI) for chronic exposure to inorganic tin based on a NOAEL of 20 mg/kg bw per day from a 2-year feeding study in rats. Using a urinary excretion fraction (0.25%) from a controlled human study along with a TDI value of 0.2 mg/kg bw per day, a Biomonitoring Equivalent (BE) was derived for urinary tin (26 MUg/g creatinine or 20 MUg/L urine). The geometric mean and the 95th percentile tin urine concentrations of the general population in U.S. (0.705 and 4.5 MUg/g creatinine) and France (0.51 and 2.28 MUg/g creatinine) are below the BE associated with the TDI, indicating that the population exposure to inorganic tin is below the exposure guidance value of 0.2 mg/kg bw per day. Overall, the robustness of pharmacokinetic data forming the basis of the urinary BE development is medium. The availability of internal dose and kinetic data in the animal species forming the basis of the assessment could improve the overall confidence in the present assessment. PMID- 27693706 TI - Human umbilical cord-derived mesenchymal stem cells in acute liver injury: Hepatoprotective efficacy, subchronic toxicity, tumorigenicity, and biodistribution. AB - Umbilical cord-derived mesenchymal stem cells (UC-MSCs) therapy might be an alternative to liver transplantation for acute or chronic liver injury. The aim of this study was to evaluate the efficacy of human UC-MSCs on carbon tetrachloride (CCl4)-induced acute liver injury. In addition, its toxicity, tumorigenicity, and biodistribution were determined. Significant hepatoprotective effects of hUC-MSCs with decreased levels of hepatocellular necrosis and lobular neutrophilic infiltration were found. Regarding the safety of hUC-MSCs, no serious hUC-MSCs-related changes (body weight, food/water consumption, clinical symptom, urinalysis, hematology, clinical chemistry, organ weight, and histopathology) were observed in a 13-week subchronic toxicity study. In a 26 week tumorigenicity study, no mice developed tumor related to hUC-MSCs transplantation up to 1 * 108 cells/kg. In particular, human mitochondrial sequence detection revealed that most hUC-MSCs were cleared from the major organs of the mice at 13 weeks after transplantation. There was no systemic toxicity or neoplastic finding either. Taken together, these results suggested that hUC-MSCs have great potential for future clinical treatment of acute liver disease. PMID- 27693707 TI - Assessment of reproductive and developmental effects of DINP, DnHP and DCHP using quantitative weight of evidence. AB - Quantitative weight of evidence (QWoE) methodology utilizes detailed scoring sheets to assess the quality/reliability of each publication on toxicity of a chemical and gives numerical scores for quality and observed toxicity. This QWoE methodology was applied to the reproductive toxicity data on diisononylphthalate (DINP), di-n-hexylphthalate (DnHP), and dicyclohexylphthalate (DCHP) to determine if the scientific evidence for adverse effects meets the requirements for classification as reproductive toxicants. The scores for DINP were compared to those when applying the methodology DCHP and DnHP that have harmonized classifications. Based on the quality/reliability scores, application of the QWoE shows that the three databases are of similar quality; but effect scores differ widely. Application of QWoE to DINP studies resulted in an overall score well below the benchmark required to trigger classification. For DCHP, the QWoE also results in low scores. The high scores from the application of the QWoE methodology to the toxicological data for DnHP represent clear evidence for adverse effects and justify a classification of DnHP as category 1B for both development and fertility. The conclusions on classification based on the QWoE are well supported using a narrative assessment of consistency and biological plausibility. PMID- 27693708 TI - Tiered application of the neutral red release and EpiOcularTM assays for evaluating the eye irritation potential of agrochemical formulations. AB - Agrochemical formulations have been underrepresented in validation efforts for implementing alternative eye irritation approaches but represent a significant opportunity to reduce animal testing. This study assesses the utility of the neutral red release assay (NRR) and EpiOcularTM assay (EO) for predicting the eye irritation potential of 64 agrochemical formulations relative to Draize data. In the NRR, formulations with an NRR50 value <= 50 mg/mL were categorized as UN GHS Cat 1 and those >250 mg/mL were classified as UN GHS Non Classified (NC). The accuracy, sensitivity, and specificity were 78, 85 and 76% and 73, 85 and 61% for identifying UN GHS 1 and NC formulations, respectively. Specificity was poor for formulations with NRR50 > 50 to <=250 mg/mL. The EO (ET-40 method) was explored to differentiate formulations that were UN GHS 1/2 and UN GHS NC. The EO resulted in accuracy, sensitivity, and specificity of 65%, 58% and 75% for identifying UN GHS NC formulations. To improve the overall performance, the assays were implemented using a tiered-approach where the NRR was run as a first-tier followed by the EO. The tiered-approach resulted in improved accuracy (75%) and balanced sensitivity (73%) and specificity (77%) for distinguishing between irritating and non-irritating agrochemical formulations. PMID- 27693709 TI - Can Sophorolipids prevent biofilm formation on silicone catheter tubes? AB - Given the impact of biofilms in health care environment and the increasing antibiotic resistance and/or tolerance, new strategies for preventing that occurrence in medical devices are obligatory. Thus, biomaterials surface functionalization with active compounds can be a valuable approach. In the present study the ability of the biosurfactants sophorolipids to prevent biofilms formation on silicone rubber aimed for medical catheters was investigated. Sophorolipids produced by Starmerella bombicola, identified by HPLC-MS/MS were used to cover silicone and surface characterization was evaluated through contact angle measurements and FTIR-ATR. Results revealed that sophorolipids presence on silicone surface decreased the hydrophobicity of the material and biofilm formation of Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922. Antibiofilm activity was evaluated through different methods and was more pronounced against S. aureus. Furthermore, biocompatibility of silicone specimens with HaCaT cells was also obtained. From this study it was possible to conclude that sophorolipids seem to be a favourable approach for coating silicone catheters. Such compounds may represent a novel source of antibiofilm agents for technological development passing through strategies of permanent functionalization of surfaces. PMID- 27693710 TI - Strategy for large-scale isolation of enantiomers in drug discovery. AB - A strategy for large-scale chiral resolution is illustrated by the isolation of pure enantiomer from a 5kg batch. Results from supercritical fluid chromatography will be presented and compared with normal phase liquid chromatography. Solubility of the compound in the supercritical mobile phase was shown to be the limiting factor. To circumvent this, extraction injection was used but shown not to be efficient for this compound. Finally, a method for chiral resolution by crystallization was developed and applied to give diastereomeric salt with an enantiomeric excess of 99% at a 91% yield. Direct access to a diverse separation tool box will be shown to be essential for solving separation problems in the most cost and time efficient way. PMID- 27693711 TI - Pharmacogenomics of the cytochrome P450 2C family: impacts of amino acid variations on drug metabolism. AB - Pharmacogenomics investigates DNA and RNA variations in the human genome related to drug responses. Cytochrome P450 (CYP) is a supergene family of drug metabolizing enzymes responsible for the metabolism of approximately 90% of human drugs. Among the major CYP isoforms, the CYP2C subfamily is of clinical significance because it metabolizes approximately 20% of clinically administrated drugs and represents several variant alleles leading to adverse drug reactions or altering drug efficacy. Here, we review recent progress on understanding the interindividual variability of the CYP2C members and the functional and clinical impact on drug metabolism. We summarize current advances in the molecular modeling of CYP2C polymorphisms and discuss the structural bases and molecular mechanisms of amino acid variants of CYP2C members that affect drug metabolism. PMID- 27693712 TI - Design of efficient computational workflows for in silico drug repurposing. AB - Here, we provide a comprehensive overview of the current status of in silico repurposing methods by establishing links between current technological trends, data availability and characteristics of the algorithms used in these methods. Using the case of the computational repurposing of fasudil as an alternative autophagy enhancer, we suggest a generic modular organization of a repurposing workflow. We also review 3D structure-based, similarity-based, inference-based and machine learning (ML)-based methods. We summarize the advantages and disadvantages of these methods to emphasize three current technical challenges. We finish by discussing current directions of research, including possibilities offered by new methods, such as deep learning. PMID- 27693713 TI - Molecular imaging in oncology drug development. AB - Tremendous breakthroughs are being made in cancer drug discovery and development. However, such breakthroughs come at a high financial cost. At a time when there is increasing pressure on drug pricing, in part because of increased life expectancy, it is more important than ever to drive new therapeutics towards patients as efficiently as possible. In this review we discuss the applications of molecular imaging in oncology drug development, with a focus on its ability to enable better early decision making, to increase efficiency and thereby to lower costs. PMID- 27693714 TI - The implications of model-informed drug discovery and development for tuberculosis. AB - Despite promising advances in the field and highly efficacious first-line treatment, an estimated 9.6 million people are still infected with tuberculosis (TB). Innovative methods are required to effectively transition the growing number of compounds into novel combination regimens. However, progression of compounds into patients occurs despite the lack of clear understanding of the pharmacokinetic-pharmacodynamic (PKPD) relationships. The PreDiCT-TB consortium was established in response to the existing gaps in TB drug development. The aim of the consortium is to develop new preclinical tools in concert with an in silico model-based approach, grounded in PKPD principles. Here, we highlight the potential impact of such an integrated framework on the various stages of TB drug development and on the dose rationale for drug combinations. PMID- 27693716 TI - Downregulation of melanogenesis: drug discovery and therapeutic options. AB - Melanin, primarily responsible in humans for hair, eye and skin pigmentation, is produced by melanocytes through a process called melanogenesis. However, the abnormal accumulation of melanin causes dermatological problems such as cafe-au lait macules ephelides (freckles), solar lentigo (age spots) and melasma, as well as cancer and vitiligo. Hence the regulation of melanogenesis is very important for treating hyperpigmentary disorders. Numerous antimelanogenic agents that target tyrosinase activity and/or stability, melanosome maturation, transfer and trafficking, or melanogenesis-related signaling pathways have been developed. This article reviews recent advances in research and development of human tyrosinase and melanogenesis-related signaling pathway inhibitors. Attempts have been made to provide a complete description of the mechanism of action of inhibitors on various melanogenesis signaling pathways. PMID- 27693717 TI - Understanding osteomyelitis and its treatment through local drug delivery system. AB - Chronic osteomyelitis is a major challenge in bone surgery. Conventional use of antibiotics is not an effective way to control the malaise due to so many reasons. Determination of optimal treatment strategy becomes difficult for the orthopaedic surgeons and as a consequence, the patients suffer not only from therapeutic failure but also due to adverse side effects of antibiotics and financial loss due to additional stay at hospitals. A wide application of carrier systems, as a medium for local delivery of antibiotics, is being used experimentally and clinically for the treatment of osteomyelitis. This kind of delivery system provides sustained higher concentration of antibiotics at the infection site with reduced possibility of toxicity. This review highlight etiology and pathophysiology of osteomyelitis, current therapeutic options with their limitations, and potentiality of biomaterial based carrier materials impregnated with antibiotics as local delivery approach. PMID- 27693715 TI - Cyclooxygenase-2 in glioblastoma multiforme. AB - Glioblastoma multiforme (GBM) represents the most prevalent brain primary tumor, yet there is a lack of effective treatment. With current therapies, fewer than 5% of patients with GBM survive more than 5 years after diagnosis. Mounting evidence from epidemiological studies reveals that the regular use of nonsteroidal anti inflammatory drugs (NSAIDs) is correlated with reduced incidence of GBM, suggesting that cyclooxygenase-2 (COX-2) and its major product within the brain, prostaglandin E2 (PGE2), are involved in the development and progression of GBM. Here, we highlight our current understanding of COX-2 in GBM proliferation, apoptosis, invasion, angiogenesis, and immunosuppression by focusing on recent in vitro and in vivo experimental data. We also discuss the feasibility of COX-2 as a therapeutic target for GBM in light of the latest human studies. PMID- 27693718 TI - Synthesis and characterization of chitosan-TiO2:Cu nanocomposite and their enhanced antimicrobial activity with visible light. AB - In the present investigation, novel strategy for the preparation of hybrid nanocomposite containing organic polymer (Chitosan) and inorganic (TiO2:Cu) nanoparticles (NPs) has been developed and demonstrated its biomedical application. The sol-gel and ultra-sonication method assisted for the preparation of uniformly distributed Chitosan-TiO2:Cu (CS-CT) nanocomposite. The structural properties of prepared CS-CT nanocomposite were studied by XRD and FTIR techniques. The XPS was used to estimate elemental composition of the nanocomposite. Thermal properties were studied using TGA. TEM and SEM analysis showed the non-spherical nature of NPs with the average mean diameter 16nm. The optical properties were analyzed with UV-vis diffuse reflectance spectroscopy to confirm optical absorption in the visible region of light. Where CS-CT showed 200% enhanced light mediated photocatalytic antimicrobial activity against microorganism (Escherichia coli and Staphylococcus aureus) as compared with control. The antimicrobial activity of CS-CT nanocomposite in presence of light is found to be enhanced than that of its components, this is due to synergistic effect of organic and inorganic material complimenting each other's activity. The OH radicals release studied by PL spectroscopy on the surface of nanocomposite was used to examine antibacterial activity. Cytotoxicity assessment of CS-CT on human fibroblast cells was performed by MTT assay. PMID- 27693719 TI - Attomolar electrochemical detection of the BCR/ABL fusion gene based on an amplifying self-signal metal nanoparticle-conducting polymer hybrid composite. AB - In the last ten years, conjugated polymers started to be used in the immobilization of nucleic acids via non-covalent interactions. In the present study, we describe the construction and use of an electrochemical DNA biosensor based on a nanostructured polyaniline-gold composite, specifically developed for the detection of the BCR/ABL chimeric oncogene. This chromosome translocation is used as a biomarker to confirm the clinical diagnosis of both chronic myelogenous leukemia (CML) and acute lymphocytic leukemia (ALL). The working principle of the biosensor rests on measuring the conductivity resulting from the non-covalent interactions between the hybrid nanocomposite and the DNA probe. The nanostructured platform exhibits a large surface area that enhances the conductivity. Positive cases, which result from the hybridization between DNA probe and targeted gene, induce changes in the amperometric current and in the charge transfer resistance (RCT) responses. Atomic force microscopy (AFM) images showed changes in the genosensor surface after exposure to cDNA sample of patient with leukemia, evidencing the hybridization process. This new hybrid sensing platform displayed high specificity and selectivity, and its detection limit is estimated to be as low as 69.4 aM. The biosensor showed excellent analytical performance for the detection of the BCR/ABL oncogene in clinical samples of patients with leukemia. Hence, this electrochemical sensor appears as a simple and attractive tool for the molecular diagnosis of the BCR/ABL oncogene even in early-stage cases of leukemia and for the monitoring of minimum levels of residual disease. PMID- 27693720 TI - Self-oriented monolayer immobilization of ovalbumin and B. cereus antibody molecules on a chemically modified surface of silicon nitride fosters the enhancement of capture of bio-agents. AB - A fast and reliable detection of biological agents in air is of a crucial importance to respond to terrorist attacks. With the aim to efficiently react to such hazards there is the need to develop highly sensitive and specific detection analytical devices for selective and quantitative detection of biological threats such as the presence of Bacillus anthracis spores and/or the presence of Ricin A toxins. In this study we explored how to achieve an oriented immobilization of antibody molecules on silicon nitride surfaces to improve their efficiency to bind to specific target molecules. In particular, we used two different methods to covalently immobilize antibody molecules on silicon nitride surfaces, and here we report the obtained results. PMID- 27693721 TI - Nucleobases Undergo Dynamic Rearrangements during RNA Tertiary Folding. AB - The tertiary structure of the GTPase center (GAC) of 23S ribosomal RNA (rRNA) as seen in cocrystals is extremely compact. It is stabilized by long-range hydrogen bonds and nucleobase stacking and by a triloop that forms within its three-way junction. Its folding pathway from secondary structure to tertiary structure has not been previously observed, but it was shown to require Mg2+ ions in equilibrium experiments. The fluorescent nucleotide 2-aminopurine was substituted at selected sites within the 60-nt GAC. Fluorescence intensity changes upon addition of MgCl2 were monitored over a time-course from 1ms to 100s as the RNA folds. The folding pathway is revealed here to be hierarchical through several intermediates. Observation of the nucleobases during folding provides a new perspective on the process and the pathway, revealing the dynamics of nucleobase conformational exchange during the folding transitions. PMID- 27693722 TI - Abnormal findings in brainstem auditory evoked response at 36-37weeks of postconceptional age in babies with neonatal chronic lung disease. AB - AIM: To examine brainstem auditory function at 36-37weeks of postconceptional age in preterm infants who are diagnosed to have neonatal chronic lung disease (CLD). STUDY DESIGN: Preterm infants, born at 31 and less weeks of gestation, were studied at 36-37weeks of postconceptional age when they were diagnosed to have neonatal CLD. Brainstem auditory evoked response (BAER) was recorded and analyzed at different click rates. RESULTS: Compared with healthy controls at the same postconceptional age, the CLD infants showed a slightly increase in BAER wave V latency. However, the I-V, and III-V interpeak intervals in the CLD infants were significantly increased. The III-V/I-III interval ratio was also significantly increased. The amplitudes of BAER waves III and V in the CLD infants tended to be reduced. These BAER findings were similar at all 21, 51 and 91/s clicks, although the abnormalities tended to be more significant at higher than at low click rates. CONCLUSION: At 36-37weeks of postconceptional age, BAER was abnormal in preterm infants who were diagnosed to have neonatal CLD. This suggests that at time when the diagnosis of CLD is made there is functional impairment, reflecting poor myelination, in the brainstem auditory pathway in preterm infants with neonatal CLD. PMID- 27693723 TI - Early determinants of vagal activity at preschool age - With potential dependence on sex. AB - BACKGROUND: In children, autonomic nervous function is related to various highly prevalent health problems and might therefore represent an early indicator of ill health. AIMS: We aimed to investigate the role of early-life exposures and physical activity (PA) as potential determinants of autonomic function at preschool age. STUDY DESIGN AND SUBJECTS: We used an existing longitudinal data set of repeated vagal tone measurements (assessed via heart rate recovery (HRR)) and retrospectively assessed early-life exposures in 1052 children (mean age: 59.4months, 47.5% girls) from 52 preschools in Germany recruited from 2008 to 2010. OUTCOME MEASURES: HRR 1min after submaximal exercise served as primary outcome. Through multilevel linear regression analysis adjusted for demographic and socioeconomic factors, we assessed the association between repeatedly measured HRR and pregnancy smoking status, breastfeeding and objectively measured PA. RESULTS: Besides significant regression coefficients for previously described correlates of HRR (sex, age), we could show positive associations of HRR with breastfeeding (six versus zero months: +4.2 beats per minute (BPM), p=0.004) and PA (+1.0BPM for 10min increase of moderate-to-vigorous PA/day, p<0.001). Smoking before and during pregnancy showed no significant association with HRR in the total sample. However, we found interactions between sex and smoking before and during pregnancy as well as between sex and breastfeeding, suggesting significant associations with HRR only in girls. CONCLUSIONS: Besides PA, early pre- and postnatal exposures seem to have long-lasting effects on children's autonomic function, still recordable at preschool age. Our data suggest that these effects might be sex-dependent. PMID- 27693724 TI - Significance of optineurin mutations in glaucoma and other diseases. AB - Glaucoma is one of the leading causes of bilateral blindness, affecting nearly 57 million people worldwide. Glaucoma is characterized by a progressive loss of retinal ganglion cells and is often associated with intraocular pressure (IOP). Normal tension glaucoma (NTG), marked by normal IOP but progressive glaucoma, is incompletely understood. In 2002, Sarfarazi et al. identified FIP-2 gene mutations responsible for hereditary NTG, renaming this gene "optineurin" (OPTN). Further investigations by multiple groups worldwide showed that OPTN is involved in several critical cellular functions, such as NF-kappaB regulation, autophagy, and vesicle transport. Recently, OPTN mutations were found to cause amyotrophic lateral sclerosis (ALS). Surprisingly, a mutation in the OPTN interacting protein, i.e., the duplication of TANK binding protein 1 (TBK1) gene, also can cause both NTG and ALS. These phenotypically distinct neuronal diseases are now merging into one common pathological mechanism by these two genes. TBK1 inhibition has emerged as a potential therapy for NTG. In this manuscript, we focus on the OPTN E50K mutation, the most common mutation for NTG, to describe the molecular mechanism of NTG by expressing a mutant Optn gene in cells and genetically modified mice. Patient iPS cells were developed and differentiated into neural cells to observe abnormal behavior and the impact of the E50K mutation. These in vitro studies were further extended to identify the inhibitors BX795 and amlexanox, which have the potential to reverse the disease-causing phenomenon in patient's neural cells. Here we show for the first time that amlexanox protects RGCs in Optn E50K knock-in mice. PMID- 27693726 TI - Utilising light-emitting diodes of specific narrow wavelengths for the optimization and co-production of multiple high-value compounds in Porphyridium purpureum. AB - The effect of specific narrow light-emitting diode (LED) wavelengths (red, green, blue) and a combination of LED wavelengths (red, green and blue - RGB) on biomass composition produced by Porphyridium purpureum is studied. Phycobiliprotein, fatty acids, exopolysaccharides, pigment content, and the main macromolecules composition were analysed to determine the effect of wavelength on multiple compounds of commercial interest. The results demonstrate that green light plays a significant role in the growth of rhodophyta, due to phycobiliproteins being able to harvest green wavelengths where chlorophyll pigments absorb poorly. However, under multi-chromatic LED wavelengths, P. purpureum biomass accumulated the highest yield of valuable products such as eicosapentaenoic acid (~2.9% DW), zeaxanthin (~586MUgg-1DW), beta-carotene (397MUgg-1DW), exopolysaccharides (2.05g/L-1), and phycobiliproteins (~4.8% DW). This increased accumulation is likely to be the combination of both photo-adaption and photo-protection, under the combined specific wavelengths employed. PMID- 27693725 TI - The impact of furfural concentrations and substrate-to-biomass ratios on biological hydrogen production from synthetic lignocellulosic hydrolysate using mesophilic anaerobic digester sludge. AB - This study evaluated the impact of furfural (a furan derivative) on hydrogen production rates and yields at initial substrate-to-microorganism ratios (S degrees /X degrees ) of 4, 2, 1, and 0.5gCOD/gVSS and furfural concentrations of 4, 2, 1, and 0.5g/L. Fermentation studies were carried out in batches using synthetic lignocellulosic hydrolysate as substrate and mesophilic anaerobic digester sludge as seed. Contrary to other literature studies where furfural was inhibitory, this study showed that furfural concentrations of up to 1g/L enhanced hydrogen production with yields as high as 19% from the control (batch without furfural). Plots of hydrogen yields against gfurfural/gsugars and hydrogen yields versus gfurfural/gbiomass showed negative linear correlation indicating that these parameters influence biohydrogen production. Regression analysis indicated that gfurfural/gsugarsinitial exerted a greater effect on the degree of inhibition of hydrogen production than gfurfural/gVSSfinal. PMID- 27693727 TI - Simultaneous hydrolysis and co-fermentation of whey lactose with wheat for ethanol production. AB - Whey permeate was used as a co-substrate to replace part of the wheat for ethanol production by Saccharomyces cerevisiae. The simultaneous saccharification and fermentation was achieved with beta-galactosidase added at the onset of the fermentation to promote whey lactose hydrolysis. Aspergillus oryzae and Kluyveromyces lactis beta-galactosidases were two enzymes selected and used in the co-fermentation of wheat and whey permeate for the comparison of their effectiveness on lactose hydrolysis. The possibility of co-fermentations in both STARGEN and jet cooking systems was investigated in 5L bioreactors. Ethanol yields from the co-fermentations of wheat and whey permeate were evaluated. It was found that A. oryzae beta-galactosidase was more efficient for lactose hydrolysis during the co-fermentation and that whey permeate supplementation can contribute to ethanol yield in co-fermentations with wheat. PMID- 27693728 TI - Simulation of biomass-steam gasification in fluidized bed reactors: Model setup, comparisons and preliminary predictions. AB - A user-defined solver integrating the solid-gas surface reactions and the multi phase particle-in-cell (MP-PIC) approach is built based on the OpenFOAM software. The solver is tested against experiments. Then, biomass-steam gasification in a dual fluidized bed (DFB) gasifier is preliminarily predicted. It is found that the predictions agree well with the experimental results. The bed material circulation loop in the DFB can form automatically and the bed height is about 1m. The voidage gradually increases along the height of the bed zone in the bubbling fluidized bed (BFB) of the DFB. The U-bend and cyclone can separate the syngas in the BFB and the flue gas in the circulating fluidized bed. The concentration of the gasification products is relatively higher in the conical transition section, and the dry and nitrogen-free syngas at the BFB outlet is predicted to be composed of 55% H2, 20% CO, 20% CO2 and 5% CH4. PMID- 27693729 TI - Comparison of two-stage acid-alkali and alkali-acid pretreatments on enzymatic saccharification ability of the sweet sorghum fiber and their physicochemical characterizations. AB - Two-stage acid/alkali pretreatment was used to enhance the saccharification efficiency of sweet sorghum fiber. The physicochemical characterizations of the pretreated fibers were evaluated by SEM, FTIR and XRD. The acid and alkali sequence in the two-stage pretreatment process was compared, and their dosage was optimized. The results indicated that the two-stage pretreatment showed better saccharification performance when compared with conventional single stage pretreatment. And compared with the acid-alkali sequence, the alkali-acid sequence achieved higher glucose yield (0.23g.g-1) under the optimized conditions, which was 1.64 and 1.21 times higher than that of the single stage and the acid-alkali pretreatments, respectively. Overall, the two-stage pretreatment process is a promising approach to achieve high fermentable glucose conversion rate of cellulosic material. PMID- 27693730 TI - Menopause and Parkinson's disease. Interaction between estrogens and brain renin angiotensin system in dopaminergic degeneration. AB - The neuroprotective effects of menopausal hormonal therapy in Parkinson's disease (PD) have not yet been clarified, and it is controversial whether there is a critical period for neuroprotection. Studies in animal models and clinical and epidemiological studies indicate that estrogens induce dopaminergic neuroprotection. Recent studies suggest that inhibition of the brain renin angiotensin system (RAS) mediates the effects of estrogens in PD models. In the substantia nigra, ovariectomy induces a decrease in levels of estrogen receptor alpha (ER-alpha) and increases angiotensin activity, NADPH-oxidase activity and expression of neuroinflammatory markers, which are regulated by estrogen replacement therapy. There is a critical period for the neuroprotective effect of estrogen replacement therapy, and local ER-alpha and RAS play a major role. Astrocytes play a major role in ER-alpha-induced regulation of local RAS, but neurons and microglia are also involved. Interestingly, treatment with angiotensin receptor antagonists after the critical period induced neuroprotection. PMID- 27693731 TI - The influence of subgroup diagnosis on radiographic and clinical outcomes after lumbar fusion for degenerative disc disorders revisited: a systematic review of the literature. AB - BACKGROUND CONTEXT: Understanding the influence of preoperative diagnosis on outcomes for lumbar fusion surgery improves the quality of research and outcomes data, and helps guide treatment decisions. PURPOSE: We sought to perform a systematic review of the literature published between 2000 and 2014 regarding lumbar fusion outcomes for degenerative disorders. An assessment of the influence of subgroup diagnosis on outcomes as well as the quality of this body of literature was performed. STUDY DESIGN: Systematic review PATIENT SAMPLE: The 100 studies ultimately included involved adult patients (n=8,706) undergoing fusion surgery for degenerative disorders of the lumbar spine. OUTCOME MEASURES: Visual analog scale (VAS) pain scores, complication rates, and determination of successful fusion METHODS: With adherence to the PRISMA guidelines, electronic searches were performed through PubMed, Scopus, and Web of Science to identify all studies involving lumbar fusion for degenerative disc disorders from January 2000 to August 2014. Studies were eligible for inclusion if they addressed adult patients treated with lumbar fusion for one of the following: stable degenerative disc disease, unstable degenerative disc disease, degenerative disc disease not specified (DDDns), herniated disc (DH), degenerative spondylolisthesis (DDDsp), and adult degenerative scoliosis (DDDsc). Abstracted data included the number of patients, preoperative diagnosis, fusion technique, complications, fusion rate, and clinical outcomes. RESULTS: One hundred articles met inclusion criteria and yielded data for 8,706 patients. Forty-three studies included data for clinical improvement (VAS scores). The mean clinical improvement in VAS scores was significantly different among the diagnoses (p<.001), with DDDsp demonstrating the highest improvement (60%) and DDDns having the lowest (45%). Eighty-five studies included data for complication rates. Complication rates differed significantly (p<.001), with the highest rate seen in the DDDsc group (18%), followed by DDDsp (14%). Seventy-eight studies included data for fusion. The pooled odds of fusion for prospective studies were 6.93 (95% CI 4.75, 10.13). There was no evidence of publication bias. CONCLUSIONS: A relationship between outcomes and subgroup diagnosis was demonstrated. This review demonstrated a higher quality of evidence in the literature, and greater overall fusion rates compared to similar studies published in the 1980s and 1990s. PMID- 27693732 TI - Oswestry Disability Index: a psychometric analysis with 1,610 patients. AB - BACKGROUND: One-fourth of the adult US population has or will experience back pain and has undergone one of a myriad of treatments. Understanding the outcomes of these many treatments from pharmacologic to surgical, from manipulation to modality, allows for a better understanding and value-driven decision making. Patient-reported outcome measures are the current standard and include general and disease-specific measures. The Oswestry Disability Index (ODI) is the most commonly used disease-specific patient-reported outcome tool to measure functional disability related to back pain. Few studies have evaluated its psychometric properties in a large patient sample using a modern tool such as the Rasch analysis model. This study aims to identify the benefits and deficiencies of the ODI as an outcome tool for assessing patients with back pain. PURPOSE: This study aimed to investigate the psychometric properties, performance, and applicability of the ODI in patients with back pain who visited a university based outpatient clinic. STUDY DESIGN: This study used a secondary analysis assessment of diagnostic tool on consecutive patients. PATIENT SAMPLE: The sample comprised 1,610 patients visiting an academic spine center. OUTCOME MEASURES: The ODI was the outcome measure. METHODS: Detailed Rasch analysis of the ODI was performed. Standard descriptive statistics were also assessed. RESULTS: The ODI performed well overall. It demonstrated suboptimal unidimensionality (ie, unexplained variance after accounting for the first dimension) of 8.3%. Person reliability was good, at 0.85, and item reliability was excellent, at 1.00. The overall item fit for the ODI was good with an outfit mean square of 1.02. The ODI had a floor effect of 29.9% and ceiling effect of 3.9%. The raw score to measure correlation of the ODI was excellent, at 0.944. CONCLUSIONS: The ODI performed relatively well overall, with some problematic findings. It had good person and item reliability, although it did not demonstrate strong evidence of unidimensionality. The ODI has moderately poor coverage, with a very large floor effect and small ceiling effect, which could present a challenge in interpreting results of scores at the end of the spectrum. PMID- 27693733 TI - Pyridoxal oxime derivative potency to reactivate cholinesterases inhibited by organophosphorus compounds. AB - Organophosphorus (OP) nerve agents (sarin, tabun VX and soman) inhibit the enzyme acetylcholinesterase (AChE, EC 3.1.1.7) by binding to its active site while preventing neurotransmission in the cholinergic synapses. The protection and treatment of this kind of poisoning are still a challenge as we are yet to discover an antidote that would be effective in all cases of poisoning. To aid the search for more efficient antidotes, we evaluated the ability of nine pyridoxal oxime derivatives, prepared by a novel synthetic pathway, to reactivate recombinant human AChE and the related purified human plasma butyrylcholinesterase (BChE, EC 3.1.1.8) inhibited by VX, tabun and paraoxon. Oximes are derivatives of vitamin B6 bearing a phenacyl moiety attached to the quaternary nitrogen atom and having various substituents on the phenyl ring. As the results have shown, the tested oximes were in general more efficient in the reactivation of OP-inhibited BChE than AChE. The highest observed rate was in the case of VX-inhibited BChE reactivation, where kobs was 0.0087min-1 and the reactivation maximum of 90% was achieved within 5h. The cholinesterases displayed a binding affinity for these derivatives in a MUmolar range no matter the substituent on their rings which was in accordance with the molecular modelling results showing a similar binding pattern for all oximes within the active site of both AChE and BChE. Such a positioning reveals also that hydroxy and a metoxy substituents at the vicinity of the oxime moiety present a possible steric hindrance explaining the reactivation results.

AB - We have developed a nano drug delivery system for the treatment of tuberculosis (TB) using rifampicin (RF) encapsulated in poly(ester amide)s nanoparticles (PEA RF-NPs), which are biocompatible polymers. In this study, biodegradable amino acid based poly(ester amide)s (PEAs) were synthesized by the poly condensation reaction and RF-loaded NPs were fabricated by the dialysis method. The surface morphology and in-vitro drug release efficiency were examined. The effect of time and temperature on the cellular uptake of PEA-RF-NPs in NR8383 cells was evaluated. Fluorescence microscopic results of PEA-RF-NPs from NR8383 cell lines suggest its potential application in treating TB. The antibacterial activity of RF against Mycobacterium smegmatis was also evaluated. Based on these results, this approach provides a new means for controlled and efficient release of RF using the PEA-NPs delivery system and is promising for the treatment of TB. PMID- 27693735 TI - A novel chitosan-polyethylene oxide nanofibrous mat designed for controlled co release of hydrocortisone and imipenem/cilastatin drugs. AB - Antimicrobial chitosan-polyethylene oxide (CS-PEO) nanofibrous mats containing ZnO nanoparticles (NPs) and hydrocortisone-imipenem/cilastatin-loaded ZnO NPs were produced by electrospinning technique. The FE-SEM images displayed that the spherical ZnO NPs were ~70-200nm in size and the CS-PEO nanofibers were very uniform and free of any beads which had average diameters within the range of ~20 130nm. For all of the nanofibrous mats, the water uptakes were the highest in acidic medium but they were decreased in the buffer and the least swellings were obtained in the alkaline environment. The drug incorporated mat preserved its bactericidal activity even after it was utilized in the release experiment for 8days in the PBS buffer. The hydrocortisone release was increased to 82% within first 12h while the release rate of imipenem/cilastatin was very much slower so that 20% of the drug was released during this period of time suggesting this nanofibrous mat is very suitable to inhibit inflammation (by hydrocortisone) and infection (using imipenem/cilastatin antibiotic and ZnO NPs) principally for the wound dressing purposes. PMID- 27693736 TI - Production of nabumetone nanoparticles: Effect of molecular weight, concentration and nature of cellulose ether stabiliser. AB - The ability of a range of hydrophilic nonionic cellulose ethers (CEs) (namely methylhydroxethylcellulose, hydroxypropylmethylcellulose, ethylhydroxyethylcellulose, hydroxyethylcellulose and hydroxypropylcellulose) to prepare stable nabumetone nanoparticles (<1000nm, as measured by laser diffraction) using wet-bead milling has been investigated. Due to the limited range of CE molecular weights commercially available, the CEs were degraded using ultrasonication for varying lengths of time to yield CEs of lower molecular weight. Of the CEs tested, only hydroxyethylcellulose was found not to stabilise the production of nabumetone nanoparticles at any of the molecular weights tested, namely viscosity average molecular weights (Mv) in the range of 236 33kg/mol. All other CEs successfully stabilised nabumetone nanoparticles, with the lower molecular weight/viscosity polymers within a series being more likely to result in nanoparticle production than their higher molecular weight counterparts. Unfortunately due to the nature of the ultrasonication process, it was not possible to compare the size of nabumetone particles produced using polymers of identical Mv. There was, however, enough similarity in the Mv of the various polymers to draw the general conclusion that there was no strong correlation between the Mv of the various polymers and their ability to produce nanoparticles. For example hydroxypropylcellulose of 112.2kg/mol or less successfully produced nanoparticles while only ethylhydroxyethylcellulose and hydroxypropylmethyl polymers of 52 and 38.8kg/mol or less produced nanoparticles. These results suggest that polymer molecular weight is not the only determinant of nanoparticle production and that structure of the polymer is at least as important as its molecular weight. In particular the hydrophobic nature of the CE was thought to be an important factor in the production of nabumetone nanoparticles: the more hydrophobic the polymer, the stronger its interaction with nabumetone and the greater its ability to produce nanoparticles. In this context HPC was the most hydrophobic polymer and HEC the least hydrophobic. PMID- 27693737 TI - Gold nanoparticles enhance 5-fluorouracil anticancer efficacy against colorectal cancer cells. AB - 5-Fluorouracil (5-FU), an antimetabolite drug, is extensively used in the treatment solid tumors. However, its severe side effects limit its clinical benefits. To enhance 5-FU anticancer efficacy and reduce its side effects it was loaded onto gold nanoparticles (GNPs) using two thiol containing ligands, thioglycolic acid (TGA) and glutathione (GSH). The GNPs were prepared at different 5-FU/ligand molar ratios and evaluated using different techniques. Anticancer efficacy of 5-FU/GSH-GNPs was studied using flow cytometry in cancerous tissue obtained from patients having colorectal cancer. The GNPs were spherical in shape and had a size of ~9-17nm. Stability of the GNPs and drug release were studied as a function of salt concentration and solution pH. Maximum 5-FU loading was achieved at 5-FU/ligand molar ratio of 1:1 and 2:1 for TGA-GNPs and GSH-GNPs, respectively. GNPs coating with pluronic F127 improved their stability against salinity. 5-FU release from GNPs was slow and pH-dependent. 5 FU/GSH-GNPs induced apoptosis and stopped the cell cycle progression in colorectal cancer cells. They also had a 2-fold higher anticancer effect compared with free 5-FU. These results confirm the potential of GNPs to enhance 5-FU anticancer efficacy. PMID- 27693738 TI - Labelling, molecular modelling and biological evaluation of vardenafil: a potential agent for diagnostic evaluation of erectile dysfunction. AB - 99mTc-tricarbonyl-vardenafil was specifically radiosynthesized for diagnostic evaluation of erectile dysfunction with a radiochemical yield ~97.2%. It was stable in saline up to 15h and in serum for more than 6h. The radiocomplex was lipophilic with a partition coefficient ~1.32 and plasma protein binding 72-76%. Its structure was determined using molecular mechanics and confirmed by NMR. In silico docking to its target PDE5 enzyme was performed. The radiocomplex inhibitory activity was assessed and its IC50 was 0.7nM. Biodistribution in normal rats and biological evaluation in rat models of erectile dysfunction were performed. The results strongly suggested that 99mTc-tricarbonyl-vardenafil is a good candidate to image erectile dysfunction in humans. PMID- 27693739 TI - Two new steroidal glycosides with unique structural feature of 14alpha-hydroxy 5beta-steroids from Reineckia carnea. AB - Two new steroidal glycosides (1-2) were isolated from the roots of Reineckia carnea, together with three known compounds (3-5). Their structures were determined on the basis of chemical methods and spectral data. Compounds 1-2 were the unique steroidal glycosides possessing structural feature of 14alpha-hydroxy 5beta-steroids, and compounds 4-5 were isolated from R. carnea for the first time. The isolated compounds (1-5) were tested in vitro for their cytotoxic activities against the A549, HepG 2 and Caski cancer cell lines. Among them, the compounds 2 and 3 showed cytotoxicity against Caski cancer cell line with IC50 values of 34.4 and 3.7MUM, respectively. PMID- 27693740 TI - Protective effects of cycloartane triterpenoides from Passiflora edulis Sims against glutamate-induced neurotoxicity in PC12 cell. AB - Four new cycloartane triterpenoids, 1alpha,3beta-dihydroxy-16-keto-24(31)-en cycloartane (1), 31-methoxyl-passifloic acid (2), cyclopassifloside XIV (3), and cyclopassifloside XV (4), together with six known compounds (5-10) were isolated from Passiflora edulis Sims. Their structures were elucidated on the basis of extensive spectroscopic analysis. All the compounds were evaluated for protective effects against damage of PC12 cell induced by glutamate according to traditional usage of the herbal medicine, and the results indicated that cycloartane triterpenoids maybe one of the active compositions of P. edulis Sims for the treatment of neurodegenerative disease. PMID- 27693741 TI - Apigenin protects mice from pneumococcal pneumonia by inhibiting the cytolytic activity of pneumolysin. AB - Streptococcus pneumoniae is an important human pathogenic bacterium that can cause various life-threatening infections. Pneumolysin (PLY), the pore-forming toxin that forms large pores in the cell membrane, is a key virulence factor secreted by S. pneumoniae that penetrates the physical defenses of the host and plays an important role in the pathogenesis of pneumococcal diseases, such as pneumonia, meningitis, bacteremia and otitis media. This study showed that apigenin, one of the bioflavonoids widely found in herbs, inhibits PLY-induced hemolysis by inhibiting the oligomerization of PLY and has no anti-S. pneumoniae activity. In addition, when PLY was incubated with human alveolar epithelial (A549) cells, apigenin could effectively alleviate PLY-mediated cell injury. In vivo studies further demonstrated that apigenin could protect mice against S. pneumoniae pneumonia. These results imply that apigenin could directly interact with PLY to decrease the pathogenicity of S. pneumoniae and that novel therapeutics against S. pneumoniae PLY might provide greater effectiveness in combatting S. pneumoniae pneumonia. PMID- 27693742 TI - A new steroidal saponin, furotrilliumoside from Trillium tschonoskii inhibits lipopolysaccharide-induced inflammation in Raw264.7 cells by targeting PI3K/Akt, MARK and Nrf2/HO-1 pathways. AB - A new steroidal saponin, furotrilliumoside (FT) was isolated from the roots and rhizomes of Trillium tschonoskii Maxim. Its structure was elucidated on the basis of 1D- and 2D-NMR spectroscopic data as well as HR-ESI-MS analysis. FT showed superior activity of inhibiting NO production of RAW264.7 cells induced by lipopolysaccharide (LPS) in the preliminary biological screening. In order to develop novel therapeutic drug for acute and chronic inflammatory disorders, the anti-inflammatory activity and underlying mechanism of FT were investigated in LPS-induced RAW264.7 cells. The results showed that FT could reduce LPS-induced expression of inducible nitric oxide synthase (iNOS) and then resulted in the decrement of NO production. More meaningful, FT could down-regulate the expression of cyclooxygenase-2 (COX-2) and decrease the expressions of pro inflammatory cytokines, tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and interleukin-1beta (IL-1beta), in both gene and protein levels. In mechanism study, FT blocked the LPS-induced upregulation of phosphorylated phosphoinositide-3-kinase and Akt (PI3K/Akt). Furthermore, FT inhibited the translocation of nuclear factor-kappa B (NF-kappaB) through the prevention of inhibitory factor kappa B alpha (IkappaBalpha) phosphorylation and degradation and also suppressed the mitogen-activated protein kinases (MAPK) signaling pathway in LPS-stimulated RAW264.7 macrophages. In addition, FT upregulated heme oxygenase-1 (HO-1) expression via nuclear translocation of nuclear factor E2 related factor 2 (Nrf2). Taken together, FT might act as a natural agent to treat some inflammatory diseases by targeting PI3K/Akt, MARK and Nrf2/HO-1 pathways. PMID- 27693743 TI - Polyphenolic compounds with antioxidant potential and neuro-protective effect from Cimicifuga dahurica (Turcz.) Maxim. AB - Three new phenolic compounds (1-3), along with five known compounds (4-8) were isolated from the rhizome of Cimicifuga dahurica (Turcz.) Maxim. Their structures were elucidated by spectroscopic methods including 1D-NMR, 2D-NMR and HR-MS techniques. DPPH method and protective effect on PC12 cells against H2O2-induced oxidative damage model were carried to evaluate the antioxidant capability of these compounds. Compound 5 showed significant antioxidant activity with IC50 values 9.33MUM in DPPH assay and compound 2 displayed marked neuro-protective effect with 87.65% cell viability at the concentration of 10MUM. Additionally, the possible structure-activity relationships of these phenolic compounds were tentatively discussed. PMID- 27693744 TI - Cornigerin, a new sesqui-lignan from the hepatoprotective fractions of Cynara cornigera L. AB - The ethanol extract of Cynara cornigera L. was fractionated and the fractions were subjected to hepatoprotective assays using Wistar albino rats at a dose of 500 and 250mg/kg. The liver injury was induced in rats using carbon tetrachloride. Biochemical parameters such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and total bilirubin were estimated as reflections of the liver condition, with silymarin as a positive control. Phytochemical investigation and chromatographic separation of the hepatoprotective fractions led to the isolation of a new sesqui-lignan namely cornigerin (1), along with eight known compounds: apigenin (2), luteolin (3), beta-sitosterol glycoside (4), apigenin 7-O-beta-D-glucopyranoside (5), luteolin 7-O-beta-D-glucopyranoside (6), apigenin-7-O-rutinoside (7), cynarin 1,5-di-O caffeoylquinic acid (8), and apigenin-7-O-beta-D-glucuronide (9). This is the first report for the isolation of 8 and 9 from this plant. PMID- 27693745 TI - Hypolipidaemic and hypoglycaemic activities of polysaccharide from Pleurotus eryngii in Kunming mice. AB - Therapeutic drugs must be developed to treat hyperglycaemia and hyperlipidaemia, which are major risk factors for developing coronary artery diseases and atherosclerosis. Pleurotus eryngii is a well-known food resource with functional properties in China. In this study, P. eryngii polysaccharide (PEP) was extracted with hot water, and its hypolipidaemic and hypoglycaemic activities were investigated. KKAy mice were divided into control and PEP groups, which were fed with high fat and PEP+high fat, respectively, for 6 weeks. Oral administration of PEP decreased body weight gain, the levels of plasma insulin, serum triglyceride, cholesterol low-density lipoprotein cholesterol and blasting blood glucose in mice. Moreover, PEP diet increased the level of high-density lipoprotein cholesterol and liver glycogen. Results indicate that PEP exhibited hypolipidaemic and hypoglycaemic activities and could be explored as possible therapeutic agents for hyperlipidaemia and hyperglycaemia. PMID- 27693746 TI - Protective effect of porphyran isolated from discolored nori (Porphyra yezoensis) on lipopolysaccharide-induced endotoxin shock in mice. AB - Porphyran, a sulfated polysaccharide, isolated from discolored nori (Porphyra yezoensis) (dc-porphyran) and one fraction (F1) purified from dc-porphyran by DEAE-chromatography showed the protective effects on LPS-induced endotoxin shock in mice. Intraperitoneal (i.p.) treatment with dc-porphyran or F1 (100mg/kg) 60min prior to i.p. injection of LPS (30mg/kg) completely protected mice from LPS lethality. At 10mg/kg concentration, F1 demonstrated more protection than dc porphyran. Intravenous (i.v.) challenge of LPS, even at 20mg/kg, was more lethal than i.p. administration; i.v. injection of F1 (100mg/kg) with LPS significantly improved the survival rate. However, i.v. dc-porphyran (100mg/kg) produced an even lower survival rate than that of LPS alone. We examined pro-inflammatory mediators such as NO and TNF-alpha in serum. F1 significantly reduced the levels of these markers. Additionally, F1 significantly decreased the malondialdehyde level in the liver, a marker of oxidative stress, while dc-porphyran had almost no effect. Furthermore, F1 significantly decreased the production of TNF-alpha and NO in peritoneal exudate cells harvested from LPS-challenged mice, while dc porphyran treatment showed a lesser decrease. Our results suggest that porphyran isolated from discolored nori, especially F1, is capable of suppressing LPS induced endotoxin shock in vivo. PMID- 27693748 TI - Emplacing India's "medicities". AB - Plans for 'medicities', announced in the Indian press from 2007 onwards, were to provide large scale 'one-stop-shops' of super-speciality medical services supplemented by diagnostics, education, research facilities, and other aspects of healthcare and lifestyle consumption. Placing this phenomenon within the recent domestic and global political economy of health, we then draw on recent research literatures on place and health to offer an analysis of the narration of these new healthcare places given in promotional texts from press media, official documents and marketing materials. We consider the implications of such analytic undertakings for the understanding of the evolving landscapes of contemporary health care in middle-income countries, and end with some reflections on the tensions now appearing in the medicity model. PMID- 27693747 TI - Modification of chemical reactivity of enzymatic hydrolysis lignin by ultrasound treatment in dilute alkaline solutions. AB - In this study, we have explored various ultrasound treatment conditions for structural modification of enzymatic hydrolysis lignin (EHL) for enhanced chemical reactivity. The key structural modifications were characterized by using a combination of analytical methods, including, Fourier Transform-Infrared spectroscopy (FTIR), Proton Nuclear Magnetic Resonance (1H NMR), Gel permeation chromatography (GPC), X-ray photoelectron spectroscopy (XPS), and Folin-Ciocalteu (F-C) method. Chemical reactivity of the modified EHL samples was determined by both 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity and their reactivity towards formaldehyde. It was observed that the modified EHL had a higher phenolic hydroxyl group content, a lower molecular weight, a higher reactivity towards formaldehyde, and a greater antioxidant property. The higher reactivity demonstrated by the samples after treatment suggesting that ultrasound is a promising method for modifying enzymatic hydrolysis lignin for value-added applications. PMID- 27693749 TI - Wnt signaling promotes hindgut fate commitment through regulating multi-lineage genes during hESC differentiation. AB - Wnt signaling plays essential roles in both embryonic pattern formation and postembryonic tissue homoestasis. High levels of Wnt activity repress foregut identity and facilitate hindgut fate through forming a gradient of Wnt signaling activity along the anterior-posterior axis. Here, we examined the mechanisms of Wnt signaling in hindgut development by differentiating human embryonic stem cells (hESCs) into the hindgut progenitors. We observed severe morphological changes when Wnt signaling was blocked by using Wnt antagonist Dkk1. We performed deep-transcriptome sequencing (RNA-seq) and identified 240 Wnt-activated genes and 2023 Wnt-repressed genes, respectively. Clusters of Wnt targets showed enrichment in specific biological functions, such as "gastrointestinal or skeletal development" in the Wnt-activated targets and "neural or immune system development" in the Wnt-repressed targets. Moreover, we adopted a high-throughput chromatin immunoprecipitation and deep sequencing (ChIP-seq) approach to identify the genomic regions through which Wnt-activated transcription factor TCF7L2 regulated transcription. We identified 83 Wnt direct target candidates, including the hindgut marker CDX2 and the genes relevant to morphogenesis (MSX1, MSX2, LEF1, T, PDGFRB etc.) through combinatorial analysis of the RNA-seq and ChIP-seq data. Together, our study identified a series of direct and indirect Wnt targets in hindgut differentiation, and uncovered the diverse mechanisms of Wnt signaling in regulating multi-lineage differentiation. PMID- 27693750 TI - A New Method for Evaluating Actual Drug Release Kinetics of Nanoparticles inside Dialysis Devices via Numerical Deconvolution. AB - Nanoparticle formulations have found increasing applications in modern therapies. To achieve desired treatment efficacy and safety profiles, drug release kinetics of nanoparticles must be controlled tightly. However, actual drug release kinetics of nanoparticles cannot be readily measured due to technique difficulties, although various methods have been attempted. Among existing experimental approaches, dialysis method is the most widely applied one due to its simplicity and avoidance of separating released drug from the nanoparticles. Yet this method only measures the released drug in the medium outside a dialysis device (the receiver), instead of actual drug release from the nanoparticles inside the dialysis device (the donor). Thus we proposed a new method using numerical deconvolution to evaluate actual drug release kinetics of nanoparticles inside the donor based on experimental release profiles of nanoparticles and free drug solution in the receptor determined by existing dialysis tests. Two computer programs were developed based on two different numerical methods, namely least square criteria with prescribed Weibull function or orthogonal polynomials as input function. The former was used for all analyses in this work while the latter for verifying the reliability of the predictions. Experimental data of drug release from various nanoparticle formulations obtained from different dialysis settings and membrane pore sizes were used to substantiate this approach. The results demonstrated that this method is applicable to a broad range of nanoparticle and microparticle formulations requiring no additional experiments. It is independent of particle formulations, drug release mechanisms, and testing conditions. This new method may also be used, in combination with existing dialysis devices, to develop a standardized method for quality control, in vitro-in vivo correlation, and for development of nanoparticles and other types of dispersion formulations. PMID- 27693751 TI - Functionalised carbon nanotubes: From intracellular uptake and cell-related toxicity to systemic brain delivery. AB - Carbon nanotubes (CNTs) have long been regarded as promising carriers in biomedicine. Due to their high surface area and unique needle-like structure, CNTs are uniquely equipped to carry therapeutic molecules across biological membranes and, therefore, have been widely researched for use in theranostic applications. The attractive properties of the CNTs entice also their use in the brain environment. Cutting edge brain-specific therapies, capable of circumventing the physical and biochemical blockage of the blood-brain barrier, could be a precious tool to tackle brain disorders. With an increasing number of applications and expanding production, the effects of direct and indirect exposure to CNTs on cellular and molecular levels and more globally the general health, must be carefully assessed and limited. In this chapter, we review the most recent trends on the development and application of CNT-based nanotechnologies, with a particular focus on the carrier properties, cell internalisation and processing, and mechanisms involved in cell toxicity. Novel approaches for CNT-based systemic therapeutic brain delivery following intravenous administration are also reviewed. Moreover, we highlight fundamental questions that should be addressed in future research involving CNTs, aiming at achieving its safe introduction into the clinics. PMID- 27693752 TI - A stabilized peptide ligand for multifunctional glioma targeted drug delivery. AB - Peptide ligands consisting of l-amino acids are subject to proteolysis in vivo. When modified on the surface of nanocarriers, those peptide ligands would readily degrade and the targeting efficacy is significantly attenuated. It has received increasing scrutiny to design stable peptide ligands for targeted drug delivery. Here, we present the design of a stable peptide ligand by the formation of a head to-tail amide bond as an example. Even though the linear l-peptide A7R (termed LA7R) can bind specifically to vascular endothelial growth factor receptor 2 (VEGFR2) and neuropilin-1 (NRP-1) that are overexpressed on glioma cells, neovasculature and glioma vasculogenic mimicry (VM), the tumor-homing capacity of LA7R is greatly impaired in vivo due to proteolysis (e.g. in the serum). A cyclic A7R (cA7R) peptide was identified by computer-aided peptide design and synthesized with high yield by combining solid phase peptide synthesis and native chemical ligation. The binding of cA7R to both receptors was theoretically and experimentally assessed. In our simulated model hydrophobic and ionic interactions dominated the binding of LA7R to receptors. It is very interesting that cA7R adopting a different structure from LA7R retained high binding affinities to receptors without affecting the hydrophobic and ionic interactions. After head-to-tail cyclization by the formation of an amide bond, cA7R exhibited exceptional stability in mouse serum. Either cA7R or LA7R was conjugated on the surface of doxorubicin (DOX) loaded liposomes (cA7R-LS/DOX or LA7R-LS/DOX). The results of in vitro cellular assays indicated that cA7R-LS/DOX not only displayed stronger anti-proliferative effect against glioma cells, but also demonstrated to be more efficient in destruction of VM and HUVEC tubes in comparison to LA7R LS/DOX and plain liposomes (LS/DOX, without peptide conjugation). cA7R conjugation could achieve significantly higher accumulation of liposomes in glioma than did LA7R conjugation, which in turn, cA7R-LS/DOX could substantially suppress subcutaneous tumor growth when compared with other DOX formulations (free DOX, LS/DOX and LA7R-LS/DOX). The designed cyclic A7R exhibited the capability of targeting glioma cells, neovasculature and VM simultaneously in vivo. Considering the ease of synthesis, high binding affinity to receptors and increased stability of cA7R peptide in the present study, the design of head-to tail cyclized peptides by the formation of amide bond based on computer-aided peptide design presents an alternative method to identify proteolytically stable peptide ligands. PMID- 27693753 TI - Viability and infectivity of fresh and cryopreserved Nosema ceranae spores. AB - The microsporidium fungus Nosema ceranae is an intracellular parasite that infects the midgut of the honey bee, Apis mellifera. A major limitation of research on N. ceranae is that the fungus is non-culturable and thus studying it depends on the seasonal availability of Nosema spores. Also, spore viability and infectivity can vary considerably, and thus there is a need for reliable methods for determining those traits. This study examined different conditions for N. ceranae spore cryopreservation at -70 degrees C, assessing spore viability and infectivity. Viability was determined by a staining procedure counting total spores numbers with bright field microscopy and un-viable spore numbers with the fluorescent dye, propidium iodide. Spore infectivity was determined with a dilution inoculation assay. Infectivity was dependent on the inoculum dose for the proportion of bees with detectable Nosema infections based on the number of spores per bee at 18days after inoculation; 4000 spores per bee or higher were needed to get approx. 100% of the inoculated bees infected. The median infective dose (ID50) was 149 spores per bee, and the minimum dose capable of causing a detectable infection was 1.28 spores. The proportion of N. ceranae infected bees correlated significantly with the number of spores per bee (r=0.98, P<0.0001). N. ceranae spores cryopreserved in water or 10% glycerol did not differ in viability compared to fresh spores, but lost infectivity when inoculated into bees. This study shows that while cryopreservation of N. ceranae spores can preserve viability, the spores can have reduced infectivity. PMID- 27693755 TI - Development and validation of a rapid and sensitive UPLC-MS/MS method for quantification of kukoamine B in human plasma: Application to a clinical pharmacokinetic study. AB - A rapid, accurate and robust method was firstly developed using ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) assay to quantify kukoamine B, which is a novel drug under clinical development for the treatment of sepsis, in human plasma. Solid-phase extraction (SPE) was used to extract kukoamine B from human plasma. The extracts were separated on a Waters Acquity HSS T3 column (2.1*50mm i.d., 1.8MUm) with a gradient elution method, using mobile phases of A (formic acid-water (1:1000, v/v)) and B(formic acid-methanol (1:1000, v/v)). Kukoamine B and internal standard (5-deuterated isotope kukoamine B) were detected under the multiple-reaction monitoring mode by an API 5500 triple quadrupole mass spectrometer with electrospray ionization. The method showed good linearity from 0.100 to 50.0ng/mL according to 1/x2 weighted linear regression analysis. Inter- and intra-batch precision of kukoamine B were less than 15% and the accuracy was within 85-115%. The extraction recoveries and matrix effect of kukoamine B at three concentration levels were consistent. The sensitivity, specificity and stabilities under various conditions were validated. In conclusion, the validation results showed that this method was rapid, accurate, robust and can successfully fulfill the requirement of clinical pharmacokinetic study of kukoamine B mesylate in Chinese healthy subjects. PMID- 27693756 TI - NQO1 and CYP450 reductase decrease the systemic exposure of rifampicin-quinone and mediate its redox cycle in rats. AB - Rifampicin (RIF) is used in regimens for infections caused by Mycobacteria accompanied by serious adverse reactions. Rifampicin-quinone (RIF-Q) is a major autoxidation product of RIF. It is not clear whether RIF-Q plays a role in RIF induced adverse reactions. Investigation of the systemic exposure of RIF-Q is helpful to better understand the role of RIF-Q in RIF induced adverse reactions. In this study, a simple and reproducible high performance liquid chromatography mass spectrometry (LC-MS) method involving a procedure to prevent the RIF from oxidation for simultaneous quantification of RIF and RIF-Q in rat plasma has been developed and validated, and applied to elucidate the systemic exposure of RIF-Q in rats. The pharmacokinetics data showed that the systemic exposure of RIF-Q was very low (0.67% of RIF, AUC0-24) in rats after oral administration of RIF. However, RIF-Q may undergo the redox cycle in vivo by the evidence that the majority of RIF-Q was reduced to RIF after an oral dose of RIF-Q. Pretreatment with the NAD(P)H: quinone oxidoreductase 1 (NQO1) specific inhibitor dicoumarol and/or cytochrome P450 reductase (CPR) inhibitor diphenyleneiodonium suppressed the redox cycle and significantly increased the systemic exposure of RIF-Q. The inhibitors also attenuated the redox cycle induced reactive oxygen species formation and cytotoxicity in RIF-Q-treated HepG2 cells. These results indicate that NQO1 and CPR play an important role in redox cycle of RIF-Q and may thus contribute to RIF-induced adverse reactions. PMID- 27693754 TI - Resolving colocalization of bacteria and metal(loid)s on plant root surfaces by combining fluorescence in situ hybridization (FISH) with multiple-energy micro focused X-ray fluorescence (ME MUXRF). AB - Metal(loid)-contamination of the environment due to anthropogenic activities is a global problem. Understanding the fate of contaminants requires elucidation of biotic and abiotic factors that influence metal(loid) speciation from molecular to field scales. Improved methods are needed to assess micro-scale processes, such as those occurring at biogeochemical interfaces between plant tissues, microbial cells, and metal(loid)s. Here we present an advanced method that combines fluorescence in situ hybridization (FISH) with synchrotron-based multiple-energy micro-focused X-ray fluorescence microprobe imaging (ME MUXRF) to examine colocalization of bacteria and metal(loid)s on root surfaces of plants used to phytostabilize metalliferous mine tailings. Bacteria were visualized on a small root section using SytoBC nucleic acid stain and FISH probes targeting the domain Bacteria and a specific group (Alphaproteobacteria, Gammaproteobacteria, or Actinobacteria). The same root region was then analyzed for elemental distribution and metal(loid) speciation of As and Fe using ME MUXRF. The FISH and ME MUXRF images were aligned using ImageJ software to correlate microbiological and geochemical results. Results from quantitative analysis of colocalization show a significantly higher fraction of As colocalized with Fe-oxide plaques on the root surfaces (fraction of overlap 0.49+/-0.19) than to bacteria (0.072+/ 0.052) (p<0.05). Of the bacteria that colocalized with metal(loid)s, Actinobacteria, known for their metal tolerance, had a higher correlation with both As and Fe than Alphaproteobacteria or Gammaproteobacteria. This method demonstrates how coupling these micro-techniques can expand our understanding of micro-scale interactions between roots, metal(loid)s and microbes, information that should lead to improved mechanistic models of metal(loid) speciation and fate. PMID- 27693757 TI - Impact of mono- and poly-ester fractions on polysorbate quantitation using mixed mode HPLC-CAD/ELSD and the fluorescence micelle assay. AB - Determination of excipient content in drug formulation is an important aspect of pharmaceutical formulation development and for analytical testing of the formulation. In this study, the influence of polysorbate subspecies, in particular mono- and poly-esters, for determining polysorbate (PS) content were investigated by comparing three of the most widely used PS quantitation approaches, the Fluorescence Micelle Assay (FMA) and Mixed-Mode High Performance Liquid Chromatography coupled with Charged Aerosol Detection (MM-CAD) or Evaporative Light Scattering Detection (MM-ELSD). FMA and MM-CAD were employed to investigate the quantitation behavior of PS20 and PS80 subspecies and corresponding degradation products in placebo formulations using forced degradation conditions at 40 degrees C for up to 12 weeks. While both methods allowed accurate and comparable quantification of neat PS at the beginning of stress studies, pronounced differences in content determination between the methods were observed at later time points, which were attributable to substantial differences in the contribution of individual mono- and poly-esters to the overall quantitation results. It was particularly surprising to find that the main component of PS20, polyoxyethylene sorbitan monolaurate, did not show a signal at the studied concentration using FMA. Moreover, the degradation of polysorbate poly-esters, was reflected much stronger in FMA than MM-CAD results. Additional experiments employing chemical oxidation and base hydrolysis to degrade PS20, quantified by FMA and MM-ELSD, also show preferential reduction in certain subspecies depending on the degradation pathway involved. For PS20 degraded by chemical oxidation, quantitation results were lower for FMA than MM ELSD, while the opposite trend was observed with base hydrolysis.

AB - Chromatographic fingerprint has been extensively used as a comprehensive approach for quality evaluation of herbal medicines (HMs). However, similar chemical profiles do not always mean similar efficacies. The present work, taking Sophora flower-bud and Sophora flower as a typical case, attempts to develop a rational strategy based on fingerprint-activity relationship modeling to realize quality evaluation from chemical consistency to effective consistency. A total of 57 batches of Sophora samples were collected and their antioxidant and hyaluronidase inhibitory activities were measured. Chemical fingerprints were established by high performance liquid chromatography (HPLC) coupled with photodiode array (PDA) detector and quadrupole time-of-flight mass spectrometry (Q-TOF MS), and similarity analyses were calculated based on eight common characteristic peaks. Subsequently, three principal bioactive markers were discovered by correlating biological effects with chemical fingerprints via partial least squares regression (PLSR) and back propagation-artificial neural network modeling (BP ANN). The selected markers were quantified by the 'single standard to determine multi-components' method, and then the quantitative data as well as their bioactive properties were subjected to principal component analysis to generate two clear-cut groups. This study not only demonstrates the necessity of effective consistency besides chemical consistency in the quality evaluation of HMs, but also provides an applicable strategy to screen out efficacy-associated markers by fingerprint-activity relationship modeling.

AB - BACKGROUND: Contact with nature improves human health; stress reduction is a mediating pathway. Stay Healthy in Nature Everyday (SHINE) is a stress reduction and health promotion intervention for low-income families at an urban Federally Qualified Health Center. We plan to evaluate two service-delivery models for SHINE and present here the intervention design and evaluation protocol. METHODS: Behavioral change theory and environmental education literature informed the intervention. Outcomes were selected after review of the literature and field tested procedures to determine what was feasible and ethical in a busy clinic serving vulnerable populations. DESIGN: We designed a randomized controlled trial to examine two levels of intensity in behavioral counseling about the health benefits of nature. Dyads consisting of a caregiver and a child aged 4 to 18 who access our pediatric primary care center are eligible. All dyads receive a pediatrician's recommendation to visit parks to experience nature and written resources (a "park prescription"). The intervention group receives added case management and an invitation to three group outings into nature with transportation, meals and activities provided. Primary outcomes measured at baseline, one month and three months post-enrollment are caregiver stress measured by PSS-10 score and salivary alpha-amylase; secondary outcomes are park prescriptions adherence, physical activity recorded by pedometer and journaling, loneliness, family cohesion and affinity to nature as measured by a validated scales. Both groups receive incentives to participation. DISCUSSION: Our intervention represents a feasible integration of recent research findings on the health benefits of nature and primary care practice.

AB - Exposure to laser irradiation on seeds brings about the changes in agronomical characteristics of the plants. Solanum melongena L. var. Mattu Gulla, a variety of brinjal is of high economic value due to its unique colour and flavour. The aim of the study was to understand the influence of Helium-Neon (He-Ne) laser irradiation on agronomical characters of Solanum melongena L. var. Mattu Gulla in the field conditions. Various growth characteristics including seed germination percentage, survival rate, plant height, number of branches, and flowers and fruits were estimated during different developmental stages of the brinjal. In addition, the chlorogenic acid content of fruits obtained from the laser irradiated seeds were quantified using reversed-phase high-performance liquid chromatography (RP- HPLC). The plants from the seeds irradiated with different doses (20, 25 and 30J/cm2) of He-Ne laser showed significant enhancement on the growth characteristics when compared to the non-irradiated control groups. He-Ne laser irradiation also improved the yield characteristics of the plants significantly in in vivo conditions in comparison with control group. 3-(4, 5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was performed using methanolic extract of matured fruit of Mattu Gulla on HepG2 and fibroblast cell lines. The IC50 values of fruit extract from laser irradiated groups were found to be similar to non-irradiated control groups. Chlorogenic acid content was found to be higher in 20J/cm2 and lower in 30J/cm2 treated fruit tissue. The current study thus elucidates the role of He-Ne laser as a biostimulator on brinjal var. Mattu Gulla not only in the in vitro conditions but also in the in vivo field conditions. PMID- 27693762 TI - The characterization of 1-(4-bromophenyl)-5-phenyl-1H-1,2,3-triazole on acute toxicity, antimicrobial activities, photophysical property, and binding to two globular proteins. AB - 1-(4-Bromophenyl)-5-phenyl-1H-1,2,3-triazole (BPT) was a newly synthesized compound. The acute toxicities of BPT to mice by intragastric administration have been determined and the result indicates that the intragastric administration of BPT did not produce any significant toxic effect on Kunming strain mice. It is also evaluated for the antimicrobial activity of BPT against three kinds of plant mycoplasma, Fusarium Wilt (race 4), Colletotrichum gloeosporioides Penz. and Xanthomonas oryzae by different method in vitro. The compound exhibited distinct inhibitory activities against Fusarium Wilt (race 4) and Colletotrichum gloeosporioides Penz. by mycelium growth rate test and the values of EC50 were 29.34 and 12.53MUg/mL respectively. And BPT had also the most potent inhibitory activities against Xanthomonas oryzae when compared with that of control drugs by the agar well diffusion method. In addition, the structural and photophysical properties of BPT including ionization energy, electron affinities, and theoretical spectrum was studied by quantum-chemical methods. Then the interaction of BPT with two kinds of globular proteins, human immunoglobulin (HIg) and bovine hemoglobin (BHg) was investigated by using UV-vis absorption spectra, synchronous fluorescence, 3D fluorescence spectra, and fluorescence titration in combination with molecular modeling. UV-vis absorption, 3D and synchronous fluorescence measurements show that BPT has influence on the microenvironment surrounding HIg or BHg in aqueous solution and the fluorescence experiments show that BPT quenches the fluorescence intensity of HIg or BHg through a static mechanism. The binding parameters including the binding constants, the number of binding site and average binding distance between BPT and HIg or BHg at different temperatures were calculated. The thermodynamic parameters suggest that the hydrophobic interaction is the predominant intermolecular forces in stabilizing the BPT-HIg or BPT-BHg complex. Molecular docking was performed to reveal that the BPT moiety binds to the hydrophobic cavity of HIg or BHg and they are in good agreement with the spectroscopic measurements.

AB - Body Image in the Primary School (Hutchinson & Calland, 2011) is a body image curriculum that is widely available but has not yet been evaluated. This study evaluates a set of 6 of the 49 available lessons from this curriculum. Seventy four girls and 70 boys aged 9-10 were recruited from four primary schools in the UK. Schools were randomly allocated into the intervention condition, where students received 6hours of body image lessons, or to lessons as normal. Body esteem was significantly higher among girls in the intervention group, compared to the control group, immediately post intervention, and at 3-month follow-up. Moreover, girls with lowest levels of body esteem at baseline reported the largest gains. Internalization was significantly lower among boys in the control group compared to the intervention group at 3-month follow-up. The pattern of results among the control group raises interesting issues for intervention evaluation. PMID- 27693764 TI - Improving patient safety reporting with the common formats: Common data representation for Patient Safety Organizations. AB - Medical errors and patient safety issues remain a significant problem for the healthcare industry in the United States. The Institute of Medicine report To Err is Human reported that there were as many as 98,000 deaths per year due to medical error as of 1999. Many authors and government officials believe that the first step on the path to improvement in patient safety is more comprehensive collection and analysis of patient safety events. The belief is that this will enable safety improvements based on data showing the nature and frequency of events that occur, and the effectiveness of interventions. This systematization of healthcare practice can be a step in the right direction toward a value based, safety conscious and effective healthcare system. To help standardize this reporting and analysis, AHRQ created Common Formats for Patient Safety data collection and reporting. This manuscript describes the development of patient safety reporting and learning through the Patient Safety Organizations (PSO)s and the Common Formats and gives readers an overview of how the system is expected to function and the breadth of development of the Common Formats to date. PMID- 27693765 TI - Two novel mitochondrial tRNA mutations, A7495G (tRNASer(UCN)) and C5577T (tRNATrp), are associated with seizures and cardiac dysfunction. AB - We describe here two novel mitochondrial mutations associated with a complex mitochondrial encephalopathy. An A to G transition at position 7495 (MT-TS1 (MT tRNSer(UCN))) was identified at 83% heteroplasmy in the muscle of a four year old female with ptosis, hypotonia, seizures, and dilated cardiomyopathy (Case 1). A homoplasmic C to T transition at position 5577 (MT-TW (MT-tRNATrp)) was found in a twenty-four year old woman with exercise intolerance, mild muscle weakness, hearing loss, seizures, and cognitive decline (Case 2). The phenotypic information provided here will assist in phenotype-genotype correlations should additional patients be reported in the future. The mutations can be added to the database of mitochondrial DNA variations in conserved regions which result in clinically diverse phenotypes with the shared markers of mitochondrial disease. PMID- 27693766 TI - Characteristics of Rosai-Dorfman Disease Primarily Involved in the Central Nervous System: 3 Case Reports and Review of Literature. AB - OBJECTIVE: This study aimed to summarize the clinical characteristics of Rosai Dorfman disease primarily involving the central nervous system and to explore diagnosis and treatment. METHODS: We analyzed the clinical, imaging, and pathologic characteristics; treatment; and prognosis in 3 cases of Rosai-Dorfman disease primarily involving the central nervous system. We also performed a literature review. RESULTS: The largest of multiple intracranial lesions was totally resected, and steroid administration and radiotherapy were performed in phases for the remaining lesions. During the 1-year follow-up period, the excised lesion did not recur, and no obvious variations were observed in the other lesions. Subtotal resection was performed of the largest of another group of multiple intracranial lesions, and the residual did not show any obvious variations during the 1-year follow-up period. The isolated lesion was totally resected and did not recur during a 2-year follow-up period. CONCLUSIONS: Rosai Dorfman disease with multiple lesions primarily involving the central nervous system is rare. Imaging characteristics are similar to meningiomas, and the pathological features include lymphocytes and plasma cells reaching tissue cells with large volume and abundant cytoplasm. Surgery is the preferred treatment, as the effects of steroid administration and radiotherapy are not apparent. PMID- 27693767 TI - Intracranial Facial Nerve Schwannomas: Current Management and Review of Literature. AB - BACKGROUND: Facial nerve schwannomas are rare, benign, nerve-sheath tumors. They can occur in any segment of the facial nerve and often clinically and radiographically mimic the common vestibular schwannoma when extending into the cerebellopontine angle. The optimal treatment strategy for intracranial facial nerve schwannomas remains controversial. METHODS: We review the literature and discuss the natural history, clinical features, diagnosis and current management of facial nerve schwannoma. RESULTS: Complete tumor resection with facial nerve preservation can be achieved in fewer cases. In most cases, the affected segment of facial nerve must be removed if the goal is to achieve complete tumor section. Regardless of type of facial nerve repair, patients can expect no better than an eventual HB grade III palsy. Stereotactic radiosurgery has good results in tumor control and facial function outcome. CONCLUSIONS: Treatment for intracranial facial nerve schwannomas depends on clinical presentation, tumor size, preoperative facial, and hearing function. Conservative management is recommended for asymptomatic patients with small tumors. Stereotactic radiosurgery may be an option for smaller and symptomatic tumors with good facial function. If tumor is large or the patient has facial paralysis, surgical resection should be indicated. If preservation of the facial nerve is not possible, total resection with nerve grafting should be performed for those patients with facial paralysis, whereas subtotal resection is best for those patients with good facial function. PMID- 27693768 TI - The Role of Intraoperative Cerebral Angiography in Transorbital Intracranial Penetrating Trauma: A Case Report and Literature Review. AB - BACKGROUND: Transorbital intracranial penetrating trauma with a retained intracranial foreign body is a rare event lacking a widely accepted diagnostic and therapeutic algorithm. Intraoperative catheter angiography (IOA) has been advocated by some authorities to rule out cerebrovascular injury before and/or after removal of the object, but no standard of care currently exists. CASE DESCRIPTION: A 19-year-old man was involved in a construction site accident whereby a framing nail penetrated the left globe, traversed the lateral bony orbit, and terminated in the midtemporal lobe. No hematoma or injury to the middle cerebral arteries (MCAs) was apparent on noncontrast head computed tomography (CT) or CT angiography, respectively. The foreign body was removed in the operating room under direct visualization after a frontotemporal craniotomy without incident. No significant venous or arterial bleeding was encountered. All visualized MCA branches appeared intact. Indocyanine green videoangiography performed immediately after object removal showed adequate filling of the MCA branches. Given these uneventful clinical and radiographic findings, IOA was not performed. Postoperative head CT and CT angiography showed no obvious neurovascular injury. On postoperative day 2, the patient was noted to have an expressive aphasia. Cerebral angiography showed absent antegrade filling of the angular artery with some retrograde perfusion. Magnetic resonance imaging confirmed an ischemic infarction in the midtemporal lobe. The patient's expressive aphasia improved to near baseline during his hospitalization and he made an excellent clinical recovery. CONCLUSIONS: In transorbital intracranial penetrating trauma with a retained intracranial object, we advocate microsurgical removal of the object under direct visualization followed immediately by IOA. IOA should be strongly considered even in the setting of minimal intraoperative bleeding and normal findings on videoangiography (a course of action that was not followed in the present case). Given that CT angiography and intraoperative videoangiography may miss a potentially treatable traumatic arterial injury, IOA can help determine whether cerebral revascularization may be necessary. PMID- 27693769 TI - Outcomes and Complications After Endovascular Treatment of Brain Arteriovenous Malformations: A Prognostication Attempt Using Artificial Intelligence. AB - PURPOSE: To identify factors influencing outcome in brain arteriovenous malformations (BAVM) treated with endovascular embolization. We also assessed the feasibility of using machine learning techniques to prognosticate and predict outcome and compared this to conventional statistical analyses. METHODS: A retrospective study of patients undergoing endovascular treatment of BAVM during a 22-year period in a national neuroscience center was performed. Clinical presentation, imaging, procedural details, complications, and outcome were recorded. The data was analyzed with artificial intelligence techniques to identify predictors of outcome and assess accuracy in predicting clinical outcome at final follow-up. RESULTS: One-hundred ninety-nine patients underwent treatment for BAVM with a mean follow-up duration of 63 months. The commonest clinical presentation was intracranial hemorrhage (56%). During the follow-up period, there were 51 further hemorrhagic events, comprising spontaneous hemorrhage (n = 27) and procedural related hemorrhage (n = 24). All spontaneous events occurred in previously embolized BAVMs remote from the procedure. Complications included ischemic stroke in 10%, symptomatic hemorrhage in 9.8%, and mortality rate of 4.7%. Standard regression analysis model had an accuracy of 43% in predicting final outcome (mortality), with the type of treatment complication identified as the most important predictor. The machine learning model showed superior accuracy of 97.5% in predicting outcome and identified the presence or absence of nidal fistulae as the most important factor. CONCLUSIONS: BAVMs can be treated successfully by endovascular techniques or combined with surgery and radiosurgery with an acceptable risk profile. Machine learning techniques can predict final outcome with greater accuracy and may help individualize treatment based on key predicting factors. PMID- 27693770 TI - In vitro antiprotozoal activity and cytotoxicity of extracts and isolated constituents from Greenwayodendron suaveolens. AB - ETHNOPHARMACOLOGICAL RELEVANCE: The Nkundo people (Nkundo area of Bolongo, Mai Ndombe district, Bandundu Province, DR Congo) use various plant parts of the tree Greenwayodendron suaveolens (Engl. & Diels) Verdc. (syn. Polyalthia suaveolens Engl. & Diels) (Annonaceae) against malaria, but its antiprotozoal constituents are not known. MATERIALS AND METHODS: The crude 80% ethanol extract from the fruits, leaves, root bark and stem bark and 16 fractions were assessed in vitro for their antiprotozoal activity against Trypanosoma brucei brucei, T. cruzi, Leishmania infantum and the chloroquine and pyrimethamine-resistant K1 strain of Plasmodium falciparum (Pf-K1). Their cytotoxic effects were evaluated against MRC 5 cells. Active constituents were isolated by chromatographic means, identified using spectroscopic methods, and evaluated in the same assays. RESULTS: The root bark extract showed the highest activity against P. falciparum K1 (IC50 0.26ug/mL) along with the stem bark alkaloid fraction (IC50 0.27ug/mL). The root bark alkaloid fraction had a pronounced activity against all selected protozoa with IC50 values <1ug/mL. The 90% methanol fractions of the different plant parts showed a pronounced activity against P. falciparum K1, with IC50 values ranging between 0.36ug/mL and 0.69ug/mL. Four constituents were isolated: the triterpenes polycarpol, and dihydropolycarpol, the latter one being reported for the first time from nature, and the alkaloids polyalthenol and N-acetyl-polyveoline. They were active to a various degree against one or more protozoa, mostly accompanied by cytotoxicity. The highest selectivity was observed for N-acetyl-polyveoline against P. falciparum K1 (IC50 2.8uM, selectivity index 10.9). CONCLUSIONS: These results may explain at least in part the traditional use of this plant species against parasitic diseases such as malaria in DR Congo. PMID- 27693771 TI - Exploring the antimalarial potential of whole Cymbopogon citratus plant therapy. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Cymbopogon citratus (lemon grass) has been used in traditional medicine as an herbal infusion to treat fever and malaria. Generally, whole plant extracts possess higher biological activity than purified compounds. However, the antimalarial activity of the whole C. citratus plant has not been experimentally tested. AIM OF THE STUDY: To evaluate the antimalarial activity of an herbal infusion and the whole Cymbopogon citratus plant in two experimental models of malaria. MATERIAL AND METHODS: The plant was dried for 10 days at room temperature and was then milled and passed through brass sieves to obtain a powder, which was administered to CBA/Ca mice with a patent Plasmodium chabaudi AS or P. berghei ANKA infection. We analysed the effects of two different doses (1600 and 3200mg/kg) compared with those of the herbal infusion and chloroquine, used as a positive control. We also assessed the prophylactic antimalarial activities of the whole C. citratus plant and the combination of the whole plant and chloroquine. RESULTS: The C. citratus whole plant exhibited prolonged antimalarial activity against both P. chabaudi AS and P. berghei ANKA. The low dose of the whole C. citratus plant displayed higher antimalarial activity than the high dose against P. berghei ANKA. As a prophylactic treatment, the whole plant exhibited higher antimalarial activity than either the herbal infusion or chloroquine. In addition, the combination of the whole C. citratus plant and chloroquine displayed higher activity than chloroquine alone against P. berghei ANKA patent infection. CONCLUSIONS: We demonstrated the antimalarial activity of the whole C. citratus plant in two experimental models. The whole C. citratus plant elicited higher anti-malarial activity than the herbal infusion or chloroquine when used as a prophylactic treatment. The antimalarial activity of the whole C. citratus plant supports continued efforts towards developing whole plant therapies for the management of malaria and other infectious diseases prevalent in resource-poor communities. PMID- 27693772 TI - Toxic polyacetylenes in the genus Bupleurum (Apiaceae) - Distribution, toxicity, molecular mechanism and analysis. AB - ETHNOPHARMACOLOGICAL RELEVANCE: The genus Bupleurum includes approximately 200 species that are widely distributed in the Northern Hemisphere, Eurasia and North Africa. Certain species of this genus have long been used as antiphlogistic, antipyretic and analgesic agents in traditional folk medicine. As described in the Chinese Pharmacopoeia, the roots of Bupleurum chinense DC. and B. scorzonerifolium Willd. are the herbal materials that compose Chaihu (Radix Bupleuri), a well-known TCM herb. AIM OF THE REVIEW: This review aims to provide up-to-date and comprehensive information regarding the distribution, toxicity, molecular mechanism and relatively new methods for the qualitative and quantitative determination of polyacetylenes in different Bupleurum species. METHOD: The information needed for this paper were sourced from publishing sites such as Elsevier, science Direct, PubMed; electronic search engines such as Scopus and Web of Science, Google scholar; other scientific database sites for chemicals such as ChemSpider, PubChem, SciFinder, and also from on line books. RESULTS: Polyacetylenes, which are widely distributed in genus Bupleurum of the Apiaceae family, have high toxicity. Among polyacetylenes, bupleurotoxin, acetylbupleurotoxin and oenanthotoxin have strong neurotoxicity. Through previous research, it was found that the toxicity of Bupleurum polyacetylenes manifested as epileptic seizures, with the target of toxicity being the brain. The neurotoxicity of polyacetylenes exhibits a relationship with the gamma aminobutyric acid (GABA) receptor pathway, and polyacetylenes have been shown to inhibit GABA-induced currents (IGABA) in a competitive manner. CONCLUSIONS: The plants of genus Bupleurum have been used in traditional medicine for thousands of years. However, certain species of this genus are poisonous, and it was attributed to the high content of polyacetylenes. The present review indicates that certain polyacetylenes in the genus Bupleurum have highly neurotoxic effects. The major challenge with regard to toxic polyacetylenes is to test their neurotoxic effects in vivo as well as in further preclinical studies, which will require large amounts of purified polyacetylenes. More reference substances should be prepared, and sophisticated analytical technologies should be developed to comprehensively assess the quality of Radix Bupleuri herbs. These investigations will be helpful for further utilization of the plants of genus Bupleurum. PMID- 27693773 TI - Add-on effect of crude rhubarb to somatostatin for acute pancreatitis: A meta analysis of randomized controlled trials. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Rhubarb is one of the common herbs used in traditional Chinese complex prescriptions for the treatment of various inflammatory diseases. We sought to determine the add-on effect of crude rhubarb to somatostatin in patients with acute pancreatitis by conducting a meta analysis. MATERIALS AND METHODS: We searched the Pubmed, EMBASE, Cochrane Library, CNKI, Wanfang, VIP databases up to November 2015. Randomized controlled trials (RCTs) comparing crude rhubarb plus somatostatin to somatostatin alone for acute pancreatitis were included. Risk ratio (RR) or weighted mean difference (WMD) with their 95% confidence interval (CI) was calculated between with and without crude rhubarb therapy. RESULTS: A total of 19 RCTs involving 1161 patients were identified. Compared with somatostatin alone, crude rhubarb plus somatostatin significantly reduced the total complications (RR 0.55; 95% CI 0.41 0.73) and APACHE II scores (WMD -1.16; 95% CI -1.91 to -0.41) as well as shortened the duration of elevated serum amylase (WMD -2.01 days; 95% CI -2.57 to -1.44), duration of abdominal pain (WMD -1.33 days; 95% CI -1.61 to -1.05), the first defecation time (WMD -2.27 days; 95% CI -3.06 to -1.47), and duration of hospital stay (WMD -6.70 days; 95% CI -8.81 to -4.60). However, there were no significant differences in total mortality rates (RR 0.61; 95% CI 0.34 to 1.12) between two groups. CONCLUSIONS: Crude rhubarb as adjuvant therapy to somatostatin appears to have additional benefits in patients with acute pancreatitis. However, interpretation of these results should be cautioned due to the methodological flaws. PMID- 27693775 TI - Myrtus communis L. and its application in treatment of Recurrent Aphthous Stomatitis. AB - ETHNOPHARMACOLOGICAL RELEVANCE: In Iranian Traditional Medicine, M. communis is a famous plant in treatment of oral ulcers and "Gholaa"- the ancient name of aphthous. OBJECTIVE: The aim of this review is to create a bridge between the traditional claims about the application of M. communis in treatment of "Gholaa" and its prescription for aphthous, the current form of "Gholaa" in modern medicine METHODS: We extracted the information about the application of M. communis in treatment of aphthous from different resources including Google scholar, Pubmed, ScienceDirect, Springer, ethnobotanical, the traditional books from Traditional Medicine Tehran University of Medical Sciences. RESULTS: In Iranian traditional texts, "Gholaa" was the corrosive diseases on the surface and inner layer of mouth and tongue and divided into three types of bloody, phlegmatic and burned black bile types. Recurrent Aphthous Stomatitis (RAS) is equal to the black bile and phlegmatic types and minor aphthous type can be matched with phlegmatic type. The corrosive propagated lesions can be herpetic aphthous. In modern medicine, M. communis essential oil and its decoction decreased the average time of pain relief and decreased the size of ulcers in patients with minor RAS without any adverse effects. The number of ulcers was not the subjects of any different clinical trials. All patients were satisfied with M. communis topical essential oil (5%), and 81% patients were satisfied with M. communis topical decoctions (5%). It appears the efficacy of M. communis is related to its analgesic, anti-inflammatory, antiseptic and wound healing effects. CONCLUSION: M. communis is effective in minor RAS as its traditional claims and confirming its efficacy in major and herpetiform RAS and comparing the efficacy of its decoction topical formulations or essential oil topical ones are required more and larger experimental and clinical investigations in future. PMID- 27693774 TI - Anti-cholinergic and Ca2+-antagonist mechanisms explain the pharmacological basis for folkloric use of Sisymbrium irio Linn. in gastrointestinal, airways and vascular system ailments. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Seeds of Sisymbrium irio Linn has been used traditionally in different regions of Pakistan for the treatment of gastrointestinal, airways and vascular system ailments. To insight the pharmacological basis, in vitro study was conducted in order to validate its folkloric uses. MATERIAL AND METHODS: 70% aqueous-methanolic extract of seeds from S. irio (Si.MEs) was tested on isolated rabbit aorta, jejunum and trachea strip hanged in tissue bath having physiological solutions aerated with carbogen and their responses were measured and recorded via Power Lab. RESULTS: The Si.MEs exhibited the transient spasmogenic effect (0.01-1.0mg/mL) on spontaneous jejunum contractions, followed by the spasmolytic effect. The addition of atropine resulted in blocking in spasmogenic effect while the spasmolytic effect was originated, suggesting the presence of an antimuscarinic effect. Likewise verapamil, Si.MEs (0.03-5mg/mL) repressed the high concentration K+(80mM)-induced contraction and also drifted the Ca2+ concentration-response curves toward right (0.3-3.0mg/mL), possibly signifying the Ca2+ channel blockade. Furthermore, Si.MEs exhibited nonspecific relaxant effect on carbachol (1uM)- and high concentration K+(80mM)-induced tracheal contractions in a way comparable to dicyclomine, suggesting the coexistence of Ca2+-antagonistic and/or antimuscarinic properties. Additionally, Si.MEs also relaxed the phenylephrine(1uM)- and high concentration K+(80mM)-induced aortic contraction (0.01-3mg/mL), suggesting blockade of Ca2+ channel. Moreover, oral administration of Si.MEs, as high as 6g per kg, did not produce lethality among the treated groups of mice. CONCLUSIONS: Aqueous-methanolic extract of seeds from S. irio (Si.MEs) exhibited the bronchodilator and gut modulator (spasmogenic and spasmolytic) activities, probably through dual blockade of muscarinic receptors and Ca2+ channels, whereas, vasodilator effect may be due to Ca2+ channels blockade. PMID- 27693776 TI - The cycle of healing - dissociation and attachment during treatment of CSA survivors. AB - Childhood sexual abuse (CSA) is an extreme traumatic event associated with numerous long lasting difficulties and symptoms (e.g., Herman, 1992). These include, among other things, the impediment of basic interpersonal structures of attachment (Rumstein-McKean & Hunsley, 2001), as well as impairment of mental integration manifested in dissociation (Van Den Bosch et al., 2003). Theoretically, attachment insecurities and dissociation are closely linked, since dissociation is generated as a way to resolve the conflicted attachment demands faced by the abused child (e.g., Liotti, 1992). Nevertheless, the directionality of association between attachment insecurities and dissociation during treatment of adult CSA survivors remains largely uninvestigated. Filling this gap, the present prospective study assessed female adult survivors of CSA who were outpatients at four treatment centers in Denmark (n=407), at the start of treatment (T1), 6 months after starting treatment (T2) and 12 months after starting treatment (T3). Results indicated that both attachment insecurities and dissociation reduced over time during treatment. Elevated attachment insecurities were associated with elevated dissociation at each of the measurements. Moreover, there was a reciprocal association between attachment avoidance and dissociation during treatment. Low levels of attachment avoidance predicted a decline in dissociation and vice versa. Findings suggest that treatment creates a cycle of healing in which rehabilitation of attachment fosters reintegration, which in turn deepens the restoration of attachment. PMID- 27693777 TI - Myclobutanil worsens nonalcoholic fatty liver disease: An in vitro study of toxicity and apoptosis on HepG2 cells. AB - Myclobutanil is a conazole class fungicide widely used as an agrichemical. It is approved for use on fruit, vegetables and seed commodities in the EU and elsewhere to control fungi such as Ascomycetes, Fungi Imperfecti and, Basidiomycetes. Its widespread use has raised the issue of possible health risks for agrarian communities and the general population, which can be exposed to residues present in food and drinking water. The toxicities identified include adverse effects on liver and kidney and on the development of male reproductive organs. Since the liver is the first-line organ in the defense against xenobiotics, toxic effects on hepatic metabolism cause degeneration, necrosis, and tissue hypertrophy. Therefore, we investigated myclobutanil's effects on the human liver cell line HepG2. We found that myclobutanil increases the amount of fatty acids in these hepatic cells, as evaluated with Oil Red O staining, and progressively reduces cell viability from 1ppm to 500ppm. Analysis of biomarkers such as Bcl-xL/Bak and Mcl-1/Bak confirmed activation of cell death pathways at low doses. Therefore, myclobutanil may play an important role in the pathogenesis and progression of chronic hepatocellular diseases in humans. PMID- 27693779 TI - Managing molar-incisor hypomineralization: A systematic review. AB - OBJECTIVES: We systematically reviewed treatment modalities for MIH-affected molars and incisors. DATA: Trials on humans with >=1 MIH molar/incisor reporting on various treatments were included. Two authors independently searched and extracted records. Sample-size-weighted annual failure rates were estimated where appropriate. The risk of bias was assessed using the Newcastle-Ottawa scale. SOURCES: Electronic databases (PubMed, Embase, Cochrane CENTRAL, Google Scholar) were screened, and hand searches and cross-referencing performed. STUDY SELECTION: Fourteen (mainly observational) studies were included. Ten trials (381 participants) investigated MIH-molars, four (139) MIH-incisors. For molars, remineralization, restorative or extraction therapies had been assessed. For restorative approaches, mean (SD) annual failure rates were highest for fissure sealants (12[6]%) and glass-ionomer restorations (12[2]%), and lowest for indirect restorations (1[3]%), preformed metal crowns (1.3 [2.1]%) and composite restorations (4[3]%). Ony study assessed extraction of molars in young patients (median age 8.2 years), the majority of them without malocclusions, but third molars in development. Spontaneous alignment of second molars was more frequent in the maxilla (55%) than the mandible (47%). For incisors, desensitizing agents successfully managed hypersensitivity. Micro-abrasion and composite veneers improved aesthetics. CONCLUSIONS: Few, mainly moderate to high-risk-studies investigated treatment of MIH. Remineralization or sealants seem suitable for MIH molars with limited severity and/or hypersensitivity. For severe cases, restorations with composites or indirect restorations or preformed metal crowns seem suitable. Prior to tooth extraction as last resort factors like the presence of a general malocclusion, patients' age and the status of neighboring teeth should be considered. No recommendations can be given for MIH-incisors. CLINICAL SIGNIFICANCE: Dentists need to consider the specific condition of each tooth and the needs and expectations of patients when deciding how to manage MIH. Strong recommendations are not possible based on the current evidence. PMID- 27693778 TI - Dentist material selection for single-unit crowns: Findings from the National Dental Practice-Based Research Network. AB - OBJECTIVES: Dentists enrolled in the National Dental Practice-Based Research Network completed a study questionnaire about techniques and materials used for single-unit crowns and an enrollment questionnaire about dentist/practice characteristics. The objectives were to quantify dentists' material recommendations and test the hypothesis that dentist's and practice's characteristics are significantly associated with these recommendations. METHODS: Surveyed dentists responded to a contextual scenario asking what material they would use for a single-unit crown on an anterior and posterior tooth. Material choices included: full metal, porcelain-fused-to-metal (PFM), all-zirconia, layered zirconia, lithium disilicate, leucite-reinforced ceramic, or other. RESULTS: 1777 of 2132 eligible dentists responded (83%). The top 3 choices for anterior crowns were lithium disilicate (54%), layered zirconia (17%), and leucite-reinforced glass ceramic (13%). There were significant differences (p<0.05) by dentist's gender, race, years since graduation, practice type, region, practice busyness, hours worked/week, and location type. The top 3 choices for posterior crowns were all-zirconia (32%), PFM (31%), and lithium disilicate (21%). There were significant differences (p<0.05) by dentist's gender, practice type, region, practice busyness, insurance coverage, hours worked/week, and location type. CONCLUSIONS: Network dentists use a broad range of materials for single-unit crowns for anterior and posterior teeth, adopting newer materials into their practices as they become available. Material choices are significantly associated with dentist's and practice's characteristics. CLINICAL SIGNIFICANCE: Decisions for crown material may be influenced by factors unrelated to tooth and patient variables. Dentists should be cognizant of this when developing an evidence-based approach to selecting crown material. PMID- 27693780 TI - Tooth wear and quality of life among adults in the United Kingdom. AB - OBJECTIVE: To explore the association between tooth wear and quality of life among adults in the United Kingdom, independently of sociodemographic factors and other common oral conditions. METHODS: We used data from 5654 dentate adults who participated in the 2009 Adult Dental Health Survey. Tooth wear was assessed during clinical examination and classified as none, mild, moderate and severe based on the worst affected tooth recorded. The numbers of teeth with mild, moderate and severe tooth wear were used as alternative measures. Oral impacts on quality of life were measured using the short form of the Oral Health Impact Profile (OHIP-14). The associations between tooth wear measures and OHIP-14 total and domain scores were tested in negative binomial regression models adjusting for sociodemographic and clinical factors. RESULTS: Overall, 62% of participants had mild, 13% moderate and 2% severe tooth wear. Adults with severe tooth wear had a crude OHIP-14 total score higher than those without tooth wear (Rate Ratio: 1.90; 95% Confidence Interval: 1.32-2.75). This association was attenuated after adjustment for confounders, particularly for other oral conditions (1.25; 95% CI: 0.90-1.73). Moreover, adults with severe tooth wear reported higher OHIP-14 domain scores in psychological discomfort (1.15; 95% CI: 1.06-1.25) and psychological disability (1.18; 95% CI: 1.10-1.30) than those without such condition. There was also evidence of a dose-response relationship; with higher OHIP-14 domain scores according to the number of teeth with severe tooth wear. CONCLUSION: This nationwide study among UK adults shows that severe tooth wear was negatively associated with psychological impacts on people's life. CLINICAL SIGNIFICANCE: Dentist should consider not only the patients' clinical characteristics, but also their impacts on quality of life and provide preventive or restorative management accordingly. PMID- 27693781 TI - Inorganic polyphosphate triggers upregulation of interleukin 11 in human osteoblast-like SaOS-2 cells. AB - Polyphosphate (polyP) is abundant in bone but its roles in signaling and control of gene expression remain unclear. Here, we investigate the effect of extracellular polyP on proliferation, migration, apoptosis, gene and protein expression in human osteoblast-like SaOS-2 cells. Extracellular polyP promoted SaOS-2 cell proliferation, increased rates of migration, inhibited apoptosis and stimulated the rapid phosphorylation of extracellular-signal-regulated kinase (ERK) directly through basic fibroblast growth factor receptor (bFGFR). cDNA microarray revealed that polyP induced significant upregulation of interleukin 11 (IL-11) at both RNA and protein levels. PMID- 27693782 TI - Differentially transcriptional regulation on cell cycle pathway by silver nanoparticles from ionic silver in larval zebrafish (Danio rerio). AB - Silver nanoparticles (AgNPs) have a strong antibacterial activity and the relevant modes of actions have regarded as direct or indirect causes of toxicity observed in the environment. In this study, the transcriptomic profiles in larval zebrafish (Danio rerio) exposed to AgNPs (about 50 nm in size) and AgNO3 as a comparative ionic silver were investigated and analyzed using differential expressed gene (DEG), Gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway analyses. Results indicated that underlying molecular mechanisms are different each other. Interestingly, the global gene expression profiling showed that cell cycle pathway is affected by both AgNPs and dissolved Ag+, however its regulation pattern was opposite each other. To the best of our knowledge, the up-regulation of cell cycle pathway by AgNPs and down-regulation by Ag+ is the first reporting and suggests the distinguished toxicological perspective from a well-known hypothesis that Ag+ mainly regulates the cell cycle. This study provides novel insights onto the genotoxicological mechanisms of AgNPs. PMID- 27693784 TI - Non-invasive stem cell tracking in hindlimb ischemia animal model using bio orthogonal copper-free click chemistry. AB - Labeling of stem cells aims to distinguish transplanted cells from host cells, understand in vivo fate of transplanted cells, particularly important in stem cell therapy. Adipose-derived mesenchymal stem cells (ASCs) are considered as an emerging therapeutic option for tissue regeneration, but much remains to be understood regarding the in vivo evidence. In this study, a simple and efficient cell labeling method for labeling and tracking of stem cells was developed based on bio-orthogonal copper-free click chemistry, and it was applied in a mouse hindlimb ischemia model. The human ASCs were treated with tetra-acetylated N azidoacetyl-d-mannosamine (Ac4ManNAz) to generate glycoprotein with unnatural azide groups on the cell surface, and the generated azide groups were fluorescently labeled by specific binding of dibenzylcyclooctyne-conjugated Cy5 (DBCO-Cy5). The safe and long-term labeling of the hASCs by this method was first investigated in vitro. Then the DBCO-Cy5-hASCs were transplanted into the hindlimb ischemia mice model, and we could monitor and track in vivo fate of the cells using optical imaging system. We could clearly observe the migration potent of the hASCs toward the ischemic lesion. This approach to design and tailor new method for labeling of stem cells may be useful to provide better understanding on the therapeutic effects of transplanted stem cells into the target diseases. PMID- 27693785 TI - The decreased N6-methyladenine DNA modification in cancer cells. AB - N6-methyladenine (6 mA) is a recently characterized DNA modification in mammalian genomes, although its biological importance remains to be resolved. Using a highly sensitive HPLC/MS/MS approach, here we report regulation of 6 mA modification in mammalian cells. To these aspects, down-regulation of 6 mA modification was first characterized in human cancer cells and tissues, relative to their normal controls. In contrast to the relative stable 5 mC modification, a dramatic decrease of 6 mA modification was found, showing that 6 mA is the most regulated DNA modification in cancers. In addition to the regulation in cancer cells, a hundreds-fold increase of 6 mA modification was found for in vitro cultured human cells, relative to the in vivo cells. This up-regulation was also confirmed with in vitro cultured mouse cells. Taken together, our study revealed distinct 6 mA modification profiles in the cancer and cultured cells. Considering its distinct regulation from that of 5 mC, our study suggests that 6 mA DNA modification may play a crucial role in cell fate transition of mammalian cells. PMID- 27693783 TI - The SH3 domain distinguishes the role of I-BAR proteins IRTKS and MIM in chemotactic response to serum. AB - The family of inverse BAR (I-BAR) domain proteins participates in a range of cellular processes associated with membrane dynamics and consists of five distinct members. Three of the I-BAR proteins, including insulin receptor tyrosine kinase substrate (IRTKS), contain an SH3 domain near their C-termini. Yet, the function of the SH3 domain of IRTKS remains uncharacterized. Here we report that in contrast to MIM, which is a prototype of I-BAR proteins and does not contain an SH3 domain, IRTKS promoted serum-induced cell migration along with enhanced phosphorylation of mitogen activated kinases Erk1/2 and p38, and activation of small GTPases Rac1 and Cdc42. In addition, cells overexpressing IRTKS exhibited an increased polarity characterized by elongated cytoplasm and extensive lamellipodia at leading edges. However, a mutant with deletion of the SH3 domain attenuated both cellular motility and p38 phosphorylation but had little effect on Erk1/2 phosphorylation. Also, a chimeric mutant in which the N terminal portion of MIM is fused with the C-terminal IRTKS, including the SH3 domain, was able to promote chemotactic response to serum and cellular polarity. In contrast, a chimeric mutant in which the N-terminal IRTKS is fused with the C terminal MIM failed to do so. Furthermore, treatment of cells with SB203580, a selective inhibitor of p38, also neutralized the effect of IRTKS on cell migration. These data indicate that the SH3 domain distinguishes the function of IRTKS in promoting cell migration and inducing signal transduction from those of SH3-less I-BAR proteins. PMID- 27693786 TI - Melittin ameliorates CVB3-induced myocarditis via activation of the HDAC2 mediated GSK-3beta/Nrf2/ARE signaling pathway. AB - Viral myocarditis (VMC) is characterized as an inflammatory process of the myocardium and can be fatal in infants and children. Melittin is a major polypeptide in honey bee venom that has been traditionally used against inflammation. However, its effect on VMC and the underlying molecular mechanism has not been reported. In this study, BALB/c mice were intraperitoneally injected with CVB3 to build a VMC model and treated with melittin. The results showed that melittin increased the mice's body weight and inhibited CVB3 replication. HE staining also showed that melittin alleviated myocardial injury in the VMC model. Flow cytometry showed that melittin inhibited myocardial cell apoptosis; in addition, real-time PCR showed that melittin decreased the expression of bax and caspase-3, and increased the expression of bcl-2. The results of echocardiographic examination showed that melittin improved cardiac function. Moreover, melittin decreased the activity of AST, CK, HBDH and LDH, and decreased the production of IL-1beta, IL-6, TNF-alpha and MCP-1 in CVB3-induced myocardial tissues. Finally, we also found that melittin increased the expression of HDAC2 and activated the GSK-3beta/Nrf2/ARE signaling pathway, whereas these changes were reversed by inhibition of HDAC2 in VMC model mice. In conclusion, our results suggested that melittin ameliorates CVB3-induced myocarditis via activation of the HDAC2-mediated GSK-3beta/Nrf2/ARE signaling pathway. PMID- 27693787 TI - Lin28a protects against postinfarction myocardial remodeling and dysfunction through Sirt1 activation and autophagy enhancement. AB - BACKGROUND: Myocardial remodeling and cardiac dysfunction prevention may represent a therapeutic approach to reduce mortality in patients with myocardial infarction (MI). We investigated the effects of Lin28a in experimental MI models, as well as the mechanisms underlying these effects. METHODS: Left anterior descending (LAD) coronary artery ligation was used to construct an MI-induced injury model. Neonatal cardiomyocytes were isolated and cultured to investigate the mechanisms underlying the protective effects of Lin28a against MI-induced injury. RESULTS: Lin28a significantly inhibited left ventricular remodeling and cardiac dysfunction after MI, as demonstrated via echocardiography and hemodynamic measurements. Lin28a reduced cardiac enzyme and inflammatory marker release in mice subjected to MI-induced injury. The mechanisms underlying the protective effects of Lin28a against MI-induced injury were associated with autophagy enhancements and apoptosis inhibition. Consistent with these findings, Lin28a knockdown aggravated cardiac remodeling and dysfunction after MI-induced injury. Lin28a knockdown also inhibited cardiomyocyte autophagy and increased cardiomyocyte apoptosis in mice subjected to MI-induced injury. Interestingly, Sirt1 knockdown abolished the protective effects of Lin28a against cardiac remodeling and dysfunction after MI, and Lin28a failed to increase the numbers of GFP-LC3-positive punctae and decrease aggresome and p62 accumulation in Sirt1 knockdown neonatal cardiomyocytes subjected to hypoxia-induced injury. CONCLUSIONS: Lin28a inhibits cardiac remodeling, improves cardiac function, and reduces cardiac enzyme and inflammatory marker release after MI. Lin28a also up regulates cardiomyocyte autophagy and inhibits cardiomyocyte apoptosis through Sirt1 activation. PMID- 27693788 TI - Enforced expression of hsa-miR-125a-3p in breast cancer cells potentiates docetaxel sensitivity via modulation of BRCA1 signaling. AB - Epigenetic gene inactivation by microRNAs (miRNAs) plays a key role in malignant transformation, prevention of apoptosis, drug resistance and metastasis. It has been shown that miR-125a is down-regulated in HER2-amplified and HER2 overexpressing breast cancers (BCa), and this miRNA is believed to serve as an important tumor suppressor. miR-125a has two mature forms: hsa-miR-125a-3p and hsa-miR-125a-5p. However, the functional details of these miRNAs in BCa, particularly during pathogenesis of drug resistance, remain largely unexplored. Herein, we reported that hsa-miR-125a-3p expression was significantly reduced in chemoresistant BCa tissues and in experimentally established chemoresistant BCa cells. hsa-miR-125a-3p knockdown promoted cell proliferation and compromised docetaxel (Dox)-induced cell death, whereas overexpression of hsa-miR-125a-3p attenuated Dox chemoresistance in BCa cells. From a mechanistic standpoint, hsa miR-125a-3p directly targeted 3'-untranslated regions (3'-UTRs) of breast cancer early onset gene 1 (BRCA1) and inhibits its protein expression via translational repression mechanism. In addition, suppression of BRCA1 expression by siRNA treatment effectively improved hsa-miR-125a-3p deficiency-triggered chemoresistance in BCa cells. Collectively, these findings suggest that hsa-miR 125a-3p may function as a tumor suppressor by regulating the BRCA1 signaling, and reintroduction of hsa-miR-125a-3p analogs could be a potential adjunct therapy for advanced/chemoresistant BCa. PMID- 27693789 TI - Plasma acylcarnitines during insulin stimulation in humans are reflective of age related metabolic dysfunction. AB - The purpose of this study was to determine if plasma acylcarnitine (AC) profiling is altered under hyperinsulinemic conditions as part of the aging process. Fifteen young, lean (19-29 years) and fifteen middle-to older-aged (57-82 years) individuals underwent a 2-hr euglycemic-hyperinsulinemic clamp. Plasma samples were obtained at baseline, 20 min, 50 min, and 120 min for analysis of AC species and amino acids. Skeletal muscle biopsies were performed after 60 min of insulin stimulation for analysis of acetyl-CoA carboxylase (ACC) phosphorylation. Insulin infusion decreased the majority of plasma short-, medium-, and long-chain (SC, MC, and LC, respectively) AC. However, during the initial 50 min, a number of MC and LC AC species (C10, C10:1, C12:1, C14, C16, C16:1, C18) remained elevated in aged individuals compared to their younger counterparts indicating a lag in responsiveness. Additionally, the insulin-induced decline in skeletal muscle ACC phosphorylation was blunted in the aged compared to young individuals (-24% vs. 56%, P < 0.05). These data suggest that a desensitization to insulin during aging, possibly at the level of skeletal muscle ACC phosphorylation, results in a diminished ability to transition to glucose oxidation indicative of metabolic inflexibility. PMID- 27693790 TI - EphA7 modulates apical constriction of hindbrain neuroepithelium during neurulation in Xenopus. AB - Eph receptor tyrosine kinases (RTKs) and their ephrin ligands play multiple roles in the developing nervous system, including cell segregation, axon guidance and synaptic plasticity. Here we report the expression and function of EphA7 in Xenopus hindbrain development. EphA7 is specifically expressed in the hindbrain throughout neurulation in Xenopus embryos. Knockdown of EphA7 by specific morpholino oligonucleotide (MO) disrupted cranial neural tube closure and disturbed apical constriction of hindbrain neuroepithelial cells, indicating weakened cell surface tension. In neural plate explants, EphA7 knockdown inhibited apical filamentous actin (F-actin) accumulation. We further showed that EphA7 is involved in the phosphorylation and activation of focal adhesion kinase (FAK) in vivo and in vitro, a key regulator of actin assembly. Our findings reveal that EphA7 functions as a critical regulator of apical constriction of hindbrain neuroepithelial cells. PMID- 27693791 TI - Sodium fluoride as a nucleating factor for Mg-actin polymerization. AB - Dynamic instability of actin filaments can be inhibited by Pi analogs beryllium fluoride and aluminium fluoride that mimic the intermediate ADP-Pi state and stabilize actin filaments. On the other hand, the phosphoryl transfer enzymes can be activated in the absence of aluminium by magnesium fluoride if magnesium ions and sodium fluoride (NaF) were present in the solution. Whether magnesium fluoride promotes functional activities of actin is not known. Here we show, for the first time, that sodium fluoride strongly accelerates polymerization of highly dynamic Mg-F-actin assembled from the monomers proteolytically cleaved between Gly42 and Val43 within the D-loop with actin-specific protease protealysin (Pln-actin), apparently due to stabilization of nuclei formed at the initial step of actin polymerization. Thereby, NaF did not inhibit the ATPase activity (subunit exchange) on Pln-F-actin, did not increase the amount of Pln-F actin sedimented by ultracentrifugation, and did not stabilize the inter-strand contacts of Pln-F-actin. On the other hand, NaF diminished accessibility of the nucleotide binding cleft of Mg-G-actin to trypsin, pointing to an additional cleft closure, and additionally protected the D-loop from the protealysin cleavage in Mg-F-actin, thus indicating that the longitudinal contacts are stabilized. We also demonstrate that in cultured cells NaF can directly promote assembly of F-actin structures under conditions when the corresponding activity of the RhoA pathway is inhibited. These data suggest that the NaF-induced assembly of actin filaments is promoted by magnesium fluoride that can be formed by the NaF-originating fluoride and the actin tightly bound magnesium. PMID- 27693792 TI - Serum starvation induces anti-apoptotic cIAP1 to promote mitophagy through ubiquitination. AB - Mitophagy is a highly specialised type of autophagy that plays an important role in regulating mitochondrial dynamics and controls cellular quality during stress. In this study, we established that serum starvation led to induction of cellular inhibitor of apoptosis protein-1 (cIAP1), which regulates mitophagy through ubiquitination. Importantly, gain and loss of function of cIAP1 resulted in concomitant alteration in mitophagy confirming the direct implication of cIAP1 in induction of mitophagy. Interestingly, it was observed that cIAP1 translocated to mitochondria to associate with TOM20, Ulk1, and LC3 to initiate mitophagy. Further, cIAP1-induced mitophagy led to dysfunctional mitochondria that resulted in abrogation of mitochondrial oxygen consumption rate along with the decrease in ATP levels. The ubiquitination of cIAP1 was found to be the critical regulator of mitophagy. The disruption of cIAP1-ubiquitin interaction by PYR41 ensured the abrogation of cIAP1-LC3 interaction and mitophagy inhibition. Our study revealed an important function of cIAP1 as a crucial molecular link between autophagy and apoptosis for regulation of mitochondrial dynamics to mitigate cellular stress. PMID- 27693793 TI - Buckling of microtubules on elastic media via breakable bonds. AB - Buckling of microtubules observed in cells has been reconstructed on a two dimensional elastic medium consisting of kinesins grafted over compressible substrates, enabling precise control of experimental conditions and quantitative analysis. However, interpretations of the observations have ambiguities due to inevitable experimental difficulties. In this study, with computer simulations, we investigated importance of the mode of interaction of microtubule with elastic medium in the buckling behavior of microtubule. By taking into consideration of forced-induced detachments of kinesins from microtubules, our simulations reproduced the previous experimental results, and showed deviations from predictions of the elastic foundation model. On the other hand, with hypothetical linkers permanently bound to microtubules, our simulation reproduced the predictions of the elastic foundation model. By analyzing the results of the simulations, we investigated as to why the difference arose. These findings indicate the importance of the mode of interaction of microtubule with the medium in the buckling behavior of microtubule. Our findings would bring new insights on buckling of microtubules in living cells. PMID- 27693794 TI - Dietary gamma oryzanol plays a significant role in the anti-inflammatory activity of rice bran oil by decreasing pro-inflammatory mediators secreted by peritoneal macrophages of rats. AB - Ricebran oil (RBO) is promoted as heart friendly oil because of its ability to maintain serum lipids at desirable levels. Inflammation also plays an important role on cardiovascular health. The role of minor constituents present in unsaponifiable fraction (UF) of RBO on inflammatory markers is not well understood. To evaluate this, we have taken RBO with UF (RBO-N), RBO stripped of UF (RBO-MCR) and RBO-MCR supplemented with UF from RBO (UFRBO) or Gamma-Oryzanol (gamma-ORY) were added in AIN-93 diets which was then fed to Wistar rats for a period of 60 days. Groundnut oil with UF (GNO-N), UF removed GNO (GNO-MCR) and GNO-MCR supplemented with UF from RBO or gamma-ORY was also used for comparison. The peritoneal macrophages from the rats were activated and pro-inflammatory mediators such as Reactive Oxygen Species (ROS), eicosanoids, cytokines, hydrolytic enzymes of lysosomal origin were monitored. The results indicated that UF of RBO and gamma-ORY supplemented in the dietary oils play a significant role in reducing the secretion of pro-inflammatory mediators by macrophages. Hence gamma-ORY in RBO significantly contributed to the anti-inflammatory properties of RBO. PMID- 27693795 TI - Local administration of a hedgehog agonist accelerates fracture healing in a mouse model. AB - Bone fracture healing is processed through multiple biological stages including the transition from cartilaginous callus to bony callus formation. Because of its specific, temporal and indispensable functions demonstrated by mouse genetic studies, Hedgehog (Hh) signaling is one of the most potent signaling pathways involved in these processes, but the effect of Hh-signaling activation by small compounds on the repair process had not yet been addressed. Here we examined therapeutic effects of local and one shot-administration of the Hh agonist known as smoothened agonist (SAG) on bone fracture healing in a mouse model. A quantitative analysis with three-dimensional micro-computed tomography showed that SAG administration increased the size of both the cartilaginous callus and bony callus at 14 days after the surgery. A histological analysis showed that SAG administration increased the number of cells expressing a proliferation marker and a chondrocyte marker in cartilaginous callus as well as the cells expressing an osteoblast marker in bony callus. These results indicate that the SAG administration resulted in an enhancement of callus formation during bone fracture healing, which is at least in part mediated by an increase in chondrocyte proliferation in cartilaginous callus and the promotion of bone formation in bony callus. Therapeutic strategies with a SAG-mediated protocol may thus be useful for the treatment of bone fractures. PMID- 27693796 TI - Automated individual-level parcellation of Broca's region based on functional connectivity. AB - Broca's region can be subdivided into its constituent areas 44 and 45 based on established differences in connectivity to superior temporal and inferior parietal regions. The current study builds on our previous work manually parcellating Broca's area on the individual-level by applying these anatomical criteria to functional connectivity data. Here we present an automated observer independent and anatomy-informed parcellation pipeline with comparable precision to the manual labels at the individual-level. The method first extracts individualized connectivity templates of areas 44 and 45 by assigning to each surface vertex within the ventrolateral frontal cortex the partial correlation value of its functional connectivity to group-level templates of areas 44 and 45, accounting for other template connectivity patterns. To account for cross-subject variability in connectivity, the partial correlation procedure is then repeated using individual-level network templates, including individual-level connectivity from areas 44 and 45. Each node is finally labeled as area 44, 45, or neither, using a winner-take-all approach. The method also incorporates prior knowledge of anatomical location by weighting the results using spatial probability maps. The resulting area labels show a high degree of spatial overlap with the gold standard manual labels, and group-average area maps are consistent with cytoarchitectonic probability maps of areas 44 and 45. To facilitate reproducibility and to demonstrate that the method can be applied to resting state fMRI datasets with varying acquisition and preprocessing parameters, the labeling procedure is applied to two open-source datasets from the Human Connectome Project and the Nathan Kline Institute Rockland Sample. While the current study focuses on Broca's region, the method is adaptable to parcellate other cortical regions with distinct connectivity profiles. PMID- 27693797 TI - The role of histamine H1, H2 and H3 receptors of ventral posteromedial nucleus of thalamus in modulation of trigeminal pain. AB - Histamine receptors are involved in supraspinal modulation of pain. In the present study, we investigated the effects of microinjection of histamine H1, H2 and H3 receptor antagonists and agonists into the ventral posteromedial (VPM) nucleus of the thalamus on two models of trigeminal pain. Right and left sides of VPM were implanted with two guide cannulas. Corneal pain was induced by local corneal surface application of hypertonic saline and the number of eye wipes was recorded. The duration of face rubbing, as an orofacial pain measure, was recorded after subcutaneous (s.c.) injection of capsaicin into the vibrissa pad. 2-pyridylethylamine (2-PEA, a histamine H1 receptor agonist, 4ug/site) and dimaprit (a histamine H2 receptor agonist, 1 and 4ug/site) suppressed corneal and orofacial pains. Mepyramine (a histamine H1 receptor antagonist) and ranitidine (a histamine H2 receptor antagonist) at the similar doses of 0.5, 2 and 8ug/site alone had no effects on trigeminal pain. Prior microinjection of mepyramine and ranitidine at a similar dose of 8ug/site inhibited the antinociceptive effects of 2-PEA (4ug/site) and dimaprit (4ug/site), respectively. Immepip (a histamine H3 receptor agonist, 1 and 4ug/site) increased, and thioperamide (a histamine H3 receptor antagonist, 2 and 8ug/site) attenuated nociceptive responses. Prior microinjection of thioperamide (8ug/site) prevented immepip (4ug/site)-induced nociception. These chemicals did not change locomotor behavior. It is concluded that post-synaptic histamine H2, and to a lesser extent H1, receptors and pre synaptic histamine H3 receptor may be involved in VPM modulation of trigeminal pain. PMID- 27693798 TI - Chronic LPSF/GQ-02 treatment attenuates inflammation and atherosclerosis development in LDLr-/- mice. AB - BACKGROUND: Atherosclerosis is a complex disorder with a multifactorial pathogenesis. We previously indicated that the new TZD LPSF/GQ-02 inhibits hepatic steatosis and inflammation, which are reported as risk factors for atherosclerosis development. Here, we explored the effects of LPSF/GQ-02 on atherosclerosis in LDLr-/- mice comparing two treatment periods. METHODS AND RESULTS: LDLr-/- mice were fed a high-fat diet for 10 and 12 weeks and received oral treatment with LPSF/GQ-02 (30mg/kg/day) or pioglitazone (20mg/kg/day) for 15 and 30 days, respectively. Both treatment protocols with LPSF/GQ-02 resulted in lower collagen density in the atherosclerotic lesions. In addition, the treatment for 15 days also decreased mRNA levels of CD40, MCP-1, ABCG1 and upregulated PPARalpha, whereas the 30-days treatment reduced the protein levels of LOX-1, p IkappaBalpha and p-NFkappaB. CONCLUSION: This study provides evidence that LPSF/GQ-02 affects the composition and growth of atherosclerotic lesions in LDLr /- mice. Moreover, our data also support previous findings showing anti inflammatory properties of LPSF/GQ-02 and reinforce the therapeutic potential of this TZD for treating atherosclerosis and inflammation-related disorders. PMID- 27693799 TI - Tanshinone IIA inhibits myocardial remodeling induced by pressure overload via suppressing oxidative stress and inflammation: Possible role of silent information regulator 1. AB - Tanshinone IIA (Tan) exerts potential protective effects against cardiovascular diseases. Oxidative stress and inflammation are involved in cardiac hypertrophy. Activation of silent information regulator 1 (SIRT1) signaling has been suggested to attenuate cardiac hypertrophy. This study aims to evaluate the antioxidative and anti-inflammatory effects of Tan treatment in pressure overload-induced myocardial remodeling and elucidated its potential mechanisms. Sprague-Dawley rats were treated with Tan in the absence or presence of the SIRT1 inhibitor sirtinol (Snl) and then subjected to transverse aortic constriction (TAC). Tan conferred cardioprotective effects by improving cardiac function, reducing apoptosis and myocardial remodeling, upregulating SIRT1, Bcl-2 expressions, and downregulating Bax and caspase-3 expressions. Snl attenuated these effects by inhibiting SIRT1 signaling. Tan treatment also reduced myocardium malondialdehyde (MDA) content, and cardiac inflammatory cytokines (TNF-alpha and IL-6) and increased myocardium superoxide dismutase (SOD) level. However, these effects were also abolished by Snl. In conclusion, these results indicate that Tan significantly attenuates TAC-induced myocardial remodeling possibly due to its strong anti-oxidative and anti-inflammatory activity. Importantly, SIRT1 signaling activation is involved in this process. PMID- 27693800 TI - Effects of ZD0947, a novel and potent ATP-sensitive K+ channel opener, on smooth muscle-type ATP-sensitive K+ channels. AB - The effects of ZD0947, a novel ATP-sensitive K+ channel (KATP channel) opener, on the activity of reconstituted KATP channels were investigated using cell-attached recordings. KATP channels were studied in HEK 293 cells by co-expression of inwardly rectifying-6 family K+ channel subunits (Kir6.x: Kir6.1 and Kir6.2) with 3 different types of sulphonylurea receptors (SUR.x: SUR1, SUR2A and SUR2B). ZD0947 (100uM) activated SUR2B/Kir6.2 channels in a concentration-dependent manner, but caused only weak activation of SUR1/Kir6.2 channels and SUR2A/Kir6.2 channels expressed in HEK 293 cells. ZD0947 reversibly suppressed diazoxide elicited SUR1/Kir6.2 channels activity and pinacidil-elicited SUR2A/Kir6.2 channel activity. However, ZD0947 did not affect SUR2B/Kir6.2 channels fully activated by 100uM pinacidil. ZD0947 had little inhibitory effects on the activity of Kir6.2DeltaC26 channels (a truncated isoform of Kir6.2) or its mutant channels (i.e. Kir6.2DeltaC26C166A) expressed in HEK 293 cells. ZD0947 also elicited activity in SUR2B/Kir6.1 channels expressed in HEK 293 cells, in a concentration-dependent manner. Therefore, ZD0947 is a relatively effective activator of smooth muscle-type KATP channels (SUR2B/Kir6.1 and SUR2B/Kir6.2) but is a partial antagonist of pancreatic-type KATP channels (i.e. SUR1/Kir6.2) and cardiac-type KATP channels (i.e. SUR2A/Kir6.2). These results suggest that a pharmacological agent can possess either agonist or antagonist actions on the activity of KATP channels, depending on the subtype of SUR.x. PMID- 27693801 TI - The alpha2beta3gamma2 GABAA receptor preferring agonist NS11394 aggravates dystonia in the phenotypic dtsz model. AB - Dystonia is a movement disorder, characterized by involuntary muscle contractions resulting in abnormal movements and/or postures. Antidystonic effects of benzodiazepines in patients with different types of dystonia could be replicated in the dtsz mutant hamster, a phenotypic model of paroxysmal dystonia. Compounds with preferred binding at specific subunits of the gamma aminobutyric acid type A (GABAA) receptor may provide a more beneficial spectrum of effects in comparison with benzodiazepines. We therefore examined the effects of the alpha1beta3gamma2 GABAA receptor preferring compound zolpidem (2.0-10.0mg/kg i.p.) and of the alpha2beta3gamma2 GABAA receptor preferring compound NS11394 (3.0-30mg/kg i.p.) on the severity of dystonia in the dtsz mutant in comparison with the benzodiazepine clonazepam (0.5-1.0mg/kg i.p.). As expected, clonazepam exerted pronounced antidystonic effects. While zolpidem showed moderate beneficial effects, NS11394 significantly increased the severity of dystonia. The present results indicate for the first time that positive GABAA receptor modulators show contrary effects on dystonia dependent on their preference for alpha-subunits. The potential link between alterations in GABAA receptor subunits and GABAergic disinhibition in dystonia deserves further attention in research on the pathophysiology and therapeutic targets.

AB - Gout is a type of arthritis, which could result from the deposition of monosodium urate crystals in joints. It can cause redness, burning pain, inflammation of joints especially in big toe. In this study, we have looked for anti-arthritic effect of coenzyme Q10 (CoQ10) on monosodium urate crystal-induced inflammation in rats and compared it with that of the non-steroidal anti-inflammatory drug, indomethacin. The evaluation was done by measuring the paw volume, antioxidant status, lipid peroxidation, lysosomal enzymes (beta-glcuronidase, beta galactosidase, N-acetyl-beta-d-glucosaminidase, acid phosphatase) activities and histopathological studies. Paw volume, the levels of lysosomal enzymes, lipid peroxidation were significantly (P<0.05) increased and the antioxidant activity status was in turn decreased in monosodium urate crystal-induced rats. CoQ10 (10mg/kg/b.w. orally) treated monosodium urate crystal-induced rats showed near normal activities of lysosomal enzymes, reduced levels of lipid peroxidation, near normal paw volume and antioxidant status. CoQ10 was also able to minimize mononuclear cell infiltration and damage to articular cartilage. Current study indicates that CoQ10 possesses anti-inflammatory effect against gouty arthritis and can be used to treat acute form of gouty arthritis. PMID- 27693803 TI - Determination of personal care products -benzophenones and parabens- in human menstrual blood. AB - Benzophenones and parabens are synthetic chemicals used in many personal care products, foods and pharmaceuticals. Benzophenones are used to protect the skin and materials from the adverse effects of UV-radiation, and parabens are used as preservatives. Despite their widespread occurrence and proven endocrine disrupting activity, relatively little is known about human exposure to these compounds. In the present work, an analytical method based on sample treatment using dispersive liquid-liquid microextraction (DLLME) for the extraction of six benzophenones (benzophenone-1, -2, -3, -6, -8 and 4-hydroxybenzophenone) and four parabens (methyl-, ethyl-, propyl- and butyl- paraben) from human menstrual blood samples, followed by ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) analysis, is proposed and validated. The method was validated using matrix-matched standard calibration followed by a recovery assay with spiked samples. The limits of detection ranged from 0.1 to 0.3ngmL-1, with recoveries of 93.8% to 108.9%, and precision (evaluated as relative standard deviation) lower than 14% for all selected compounds. This method was successfully applied for the determination of the target compounds in 25 samples of human menstrual blood. Methylparaben and benzophenone-3 were the most frequently detected compounds (96%). PMID- 27693804 TI - Emergency management of severe hyperkalemia: Guideline for best practice and opportunities for the future. AB - Hyperkalemia is a common electrolyte disorder, especially in chronic kidney disease, diabetes mellitus, or heart failure. Hyperkalemia can lead to potentially fatal cardiac dysrhythmias, and it is associated with increased mortality. Determining whether emergency therapy is warranted is largely based on subjective clinical judgment. The Investigator Network Initiative Cardiovascular and Renal Clinical Trialists (INI-CRCT) aimed to evaluate the current knowledge pertaining to the emergency treatment of hyperkalemia. The INI-CRCT developed a treatment algorithm reflecting expert opinion of best practices in the context of current evidence, identified gaps in knowledge, and set priorities for future research. We searched PubMed (to August 4, 2015) for consensus guidelines, reviews, randomized clinical trials, and observational studies, limited to English language but not by publication date. Treatment approaches are based on small studies, anecdotal experience, and traditional practice patterns. The safety and real-world effectiveness of standard therapies remain unproven. Prospective research is needed and should include studies to better characterize the population, define the serum potassium thresholds where life-threatening arrhythmias are imminent, assess the potassium and electrocardiogram response to standard interventions. Randomized, controlled trials are needed to test the safety and efficacy of new potassium binders for the emergency treatment of severe hyperkalemia in hemodynamically stable patients. Existing emergency treatments for severe hyperkalemia are not supported by a compelling body of evidence, and they are used inconsistently across institutions, with potentially significant associated side effects. Further research is needed to fill knowledge gaps, and definitive clinical trials are needed to better define optimal management strategies, and ultimately to improve outcomes in these patients. PMID- 27693807 TI - An image-processing based technique to obtain instantaneous horizontal walking and running speed. AB - Walking and running speed is a fundamental parameter studied in a wide range of areas such as sport biomechanics, rehabilitation, health promotion of the elderly, etc. Given that walking or running speed is not constant even within a stride, instantaneous changes in the body motion need to be evaluated to better understand one's performance. In this study, a new cost- and time- efficient methodology to determine instantaneous horizontal walking and running speed was developed. The newly developed method processes the movies taken with a (high speed) camera. It consists of five sub-steps, which are performed in a serial order: (1) Subtraction of the background image, (2) filtering, (3) binarization and centroid determination, (4) transformation to the laboratory coordinate system and (5) differentiation. To test the accuracy of the newly developed method, the output (position and speed) was compared with the data obtained using motion capture. The average root mean squared (RMS) error (difference between the outputs of the newly developed method and motion capture) of position-time curves was 0.011m-0.033m. The average RMS error of speed-time curves was 0.054m/s 0.076m/s. It was shown that this new method produces accurate outputs of instantaneous walking and running speed. PMID- 27693806 TI - Impaired postural control in children with developmental coordination disorder is related to less efficient central as well as peripheral control. AB - BACKGROUND: Developmental coordination disorder (DCD) is a neurodevelopmental impairment that affects approximately 6% of children in primary school age. Children with DCD are characterized by impaired postural control. It has yet to be determined what effect peripheral and central neuromuscular control has on their balance control. OBJECTIVE: The aim of this study was to investigate the underlying mechanisms to impaired postural control in children with DCD using the rambling-trembling decomposition of the center of pressure (CoP). METHOD: Nine children with DCD (9.0+/-0.5years, 7 boys, 2 girls) and 10 age- and gender matched typically developing children (TD) with normal motor proficiency (9.1+/ 0.4years, 7 boys and 3 girls) performed 3*30s bipedal standing on a force plate in six sensory conditions following the sensory organization procedure. Sway length was measured and rambling-trembling decomposition of CoP was calculated in medio-lateral (ML) and anterior-posterior (AP) direction. RESULTS: Both rambling and trembling were larger for the children with DCD in AP (p=0.031; p=0.050) and ML direction (p=0.025; p=0.007), respectively. ML rambling trajectories did not differ in any conditions with fixed support surface. In ML direction children with DCD had a lower relative contribution of rambling to total sway (p=0.013). CONCLUSION: This study showed that impaired postural control in children with DCD is associated with less efficient supraspinal control represented by increased rambling, but also by reduced spinal feedback control or peripheral control manifested as increased trembling. PMID- 27693805 TI - Role of dietary fatty acids in liver injury caused by vinyl chloride metabolites in mice. AB - BACKGROUND: Vinyl chloride (VC) causes toxicant-associated steatohepatitis at high exposure levels. Recent work by this group suggests that underlying liver disease may predispose the liver to VC hepatotoxicity at lower exposure levels. The most common form of underlying liver disease in the developed world is non alcoholic fatty liver disease (NAFLD). It is well-known that the type of dietary fat can play an important role in the pathogenesis of NAFLD. However, whether the combination of dietary fat and VC/metabolites promotes liver injury has not been studied. METHODS: Mice were administered chloroethanol (CE - a VC metabolite) or vehicle once, 10weeks after being fed diets rich in saturated fatty acids (HSFA), rich in poly-unsaturated fatty acids (HPUFA), or the respective low-fat control diets (LSFA; LPUFA). RESULTS: In control mice, chloroethanol caused no detectable liver injury, as determined by plasma transaminases and histologic indices of damage. In HSFA-fed mice, chloroethanol increased HSFA-induced liver damage, steatosis, infiltrating inflammatory cells, hepatic expression of proinflammatory cytokines, and markers of endoplasmic reticulum (ER) stress. Moreover, markers of inflammasome activation were increased, while markers of inflammasome inhibition were downregulated. In mice fed HPUFA all of these effects were significantly attenuated. CONCLUSIONS: Chloroethanol promotes inflammatory liver injury caused by dietary fatty acids. This effect is far more exacerbated with saturated fat, versus poly-unsaturated fat; and strongly correlates with a robust activation of the NLRP3 inflammasome in the saturated fed animals only. Taken together these data support the hypothesis that environmental toxicant exposure can exacerbate the severity of NAFLD/NASH. PMID- 27693808 TI - Intravenous lacosamide in seizure emergencies: Observations from a hospitalized in-patient adult population. AB - PURPOSE: to evaluate the efficacy and safety of intravenous (IV) lacosamide (LCM) in the treatment of seizure clusters (SC) and status epilepticus (SE) in hospitalized adult patients. METHODS: we prospectively analyzed treatment response, seizure outcome, and adverse effects of IV LCM in 38 patients with seizure emergencies (15 with SC, 23 with SE) during a hospital stay. The loading dose of IV LCM was 200-400mg and the maintenance dose was 200-400mg daily. Response to IV LCM was evaluated within 20min, 4h and 24h of LCM infusion. RESULTS: an acute anti-seizure effect after IV LCM was especially evident when it was first used - (SC) or second line (established SE) treatment. In particular, 87% of SC patients (13/15) and 80% of established SE (8/10) demonstrated response to LCM treatment, while no patients with super-refractory SE (0/8) responded to IV LCM according to our criteria. The loading of IV LCM was well tolerated, with mild adverse effects (2/38 temporary dizziness). In most patients, during and after administration of the loading dose of IV LCM a temporary (30min-1h) sedation was observed. No ECG and laboratory values-changes were documented in any of the patients. CONCLUSIONS: LCM is an effective and well-tolerated treatment when used to treat SC in hospitalized adult patients. As add-on therapy, it may be useful to stop seizure activity in patients with focal SE not responding to first/second-line intravenous AEDs. PMID- 27693809 TI - Ultrastructural Investigation of Pelvic Peritoneum in Patients With Chronic Pelvic Pain and Subtle Endometriosis in Association With Chromoendoscopy. AB - STUDY OBJECTIVE: To evaluate the pelvic peritoneum under chromoendoscopy by scanning electron microscopy (SEM) as well as light microscopy with hematoxylin and eosin staining and immunohistochemistry (IHC) assays in patients with chronic pelvic pain (CPP) associated with subtle endometriosis. DESIGN: Case series study (Canadian Task Force classification II). SETTING: A referral academic community tertiary medical center. PATIENTS: Three women aged 29 to 37 years were referred to the obstetrics and gynecology clinic of the tertiary university hospital with CPP. They were suspicious for endometriosis, were not responding to medical treatments, and had undergone previous pelvic laparoscopy to determine the stage of endometriosis and preparation of peritoneal samples under the guidance of staining with methylene blue in 0.25% dilution. INTERVENTIONS: Comparison of stained and unstained pelvic peritoneal samples after the instillation of 0.25% methylene blue into the pelvic cavity. MEASUREMENTS AND MAIN RESULTS: In 3 patients, laparoscopic examination showed minimal endometriosis. A total of 18 samples (9 stained and 9 unstained) from the 3 patients were prepared for SEM. Ten of the samples (55.6%) showed microstructural peritoneal destruction (7 of 9 stained [77.7%] and 3 of 9 [33.4%] unstained). Eighteen samples (9 stained and 9 unstained) from the 3 patients were also prepared for IHC. Six of these samples (33.3%) were S-100-positive, including 4 of 9 (44.4%) stained samples and 2 of 9 (22.2%) unstained samples. CONCLUSIONS: In general, in the context of CPP and endometriosis, there is no established relationship between the severity of pain and stage of endometriosis. In the pathophysiology of CPP associated with endometriosis, ultrastructural changes can play a significant role. Under methylene blue staining, some destroyed areas were detected, but the stained areas do not necessarily correlate with increased microstructural peritoneal destruction. PMID- 27693810 TI - First Case of ROLL Technique for Mesorectal Recurrence Excision. AB - The radio-guided occult lesion localization (ROLL) technique has been in use since the mid-1990s, mainly in breast surgery. Today, ROLL is used for numerous oncologic pathologies, including parathyroid lesions, melanomas, and colorectal tumors. We report a patient with an 11-mm left mesorectal solitary recurrence of a primary ovarian cancer in whom the ROLL technique was used to identify the implant. A radioisotope was introduced through a 22-gauge needle with endoscopic ultrasound technique using an linear echo endoscope. On the day of surgery, the patient's perianal region was scanned with a gamma probe to identify the area of maximal radioactivity, to determine the optimal placement of the incision over the lesion. After macroscopic excision of the lesion, radioactivity was measured in the lesion bed to ensure complete removal of affected tissues. In our case, the ROLL technique was performed safely for the detection and excision of a recurrent lesion of difficult identification. To our knowledge, this is the first reported case involving use of the ROLL technique to aid the excision of a mesorectal lesion. PMID- 27693811 TI - Book lung development in embryos of the cobweb spider, Parasteatoda tepidariorum C. L. Koch, 1841 (Araneomorphae, Theridiidae). AB - Light and transmission electron microscopy were used to study the development of book lungs in embryos of the spider Parasteatoda tepidariorum. There is a bilateral cluster of temporary lamellae that form just posterior to the second opisthosomal (O2) limb buds. These lamellae are replaced by advanced embryo (AE) book lungs that continue into postembryonic stages. Results herein agree with earlier suggestions that the O2 limb buds become the AE book lungs. Each O2 limb bud merges with the ventral surface of the O2 segment, where the limb bud/book lung is internalized by covering with epidermis. A strand of tissue (entapophysis) from the epidermis at the posterior opisthosoma provides precursor cells for the book lung lamellae, and possibly entapophysis cells induce limb bud cells to align and produce lamellae. Electron micrographs show the different modes (I-III) of lumen formation. The result is a spiracle, atrium and alternating air and hemolymph channels. A hypothesis is presented for the role of precursor cell polarity in producing the planar tissue polarity of the channels. Some type of apical/apical affinity results in air channels, while basal/basal affinity results in hemolymph channels. Strong basal/basal affinity is likely as opposed cells in hemolymph channels extend basal processes that span the channel and start pillar trabeculae that continue in postembryonic stages. PMID- 27693812 TI - Lifestyle factors and prostate-specific antigen (PSA) testing in UK Biobank: Implications for epidemiological research. AB - BACKGROUND: The central role of prostate-specific antigen (PSA) testing in the diagnosis of prostate cancer leads to the possibility that observational studies that report associations between risk factors and prostate cancer could be affected by detection bias. This study aims to investigate whether reported risk factors for prostate cancer are associated with PSA testing in a large middle aged population-based cohort in the UK. METHODS: The cross-sectional association between a wide range of sociodemographic, lifestyle, dietary and health characteristics with PSA testing was examined in 212,039 men aged 40-69 years in UK Biobank. RESULTS: A total of 62,022 (29%) men reported they had ever had a PSA test. A wide range of factors was associated with a higher likelihood of PSA testing including age, height, education level, family history of prostate cancer, black ethnic origin, not being in paid/self-employment, living with a wife or partner, having had a vasectomy, being diagnosed with cancer or hypertension and having a high dietary intake of cereal, cooked and salad/raw vegetables, fresh fruit and tea. Conversely, socioeconomic deprivation, Asian ethnic origin, current smoking, low alcohol intake, high body-mass index, high coffee consumption and being diagnosed with diabetes, heart disease or stroke were associated with a lower likelihood of PSA testing. CONCLUSIONS: A variety of sociodemographic, lifestyle and health-related characteristics are associated with PSA testing, suggesting that observed associations of some of these traits with risk for prostate cancer in epidemiological studies may be, at least partially, due to detection bias. PMID- 27693813 TI - Irisin inhibition of growth hormone secretion in cultured tilapia pituitary cells. AB - Irisin, the product of fibronectin type III domain-containing protein 5 (FNDC5) gene, is well-documented to be a regulator of energy metabolism. At present, not much is known about its biological function in non-mammalian species. In this study, a full-length tilapia FDNC5 was cloned and its tissue expression pattern has been confirmed. Based on the sequence obtained, we produced and purified recombinant irisin which could induce uncoupling protein 1 (UCP1) gene expression in tilapia hepatocytes. Further, the rabbit polyclonal irisin antiserum was produced and its specificity was confirmed by antiserum preabsorption. In tilapia pituitary cells, irisin inhibited growth hormone (GH) gene expression and secretion and triggered rapid phosphorylation of Akt, Erk1/2, and p38 MAPK. Furthermore, irisin-inhibited GH mRNA expression could be prevented by inhibiting PI3K/Akt, MEK1/2, and p38 MAPK, respectively. Apparently, fish irisin can act directly at the pituitary level to inhibit GH transcript expression via multiple signaling pathways. PMID- 27693814 TI - Retinal gap junctions are involved in rhythmogenesis of neuronal activity at remote locations - Study on infra-slow oscillations in the rat olivary pretectal nucleus. AB - A subpopulation of olivary pretectal nucleus (OPN) neurons fire action potentials in a rhythmic manner with an eruption of activity occurring approximately every two minutes. These infra-slow oscillations depend critically on functional retinal input and are subject to modulation by light. Interestingly, the activity of photoreceptors is necessary for the emergence of the rhythm and while classic photoreceptors (rods and cones) are necessary in darkness and dim light, melanopsin photoreceptors are indispensable in bright light. Using pharmacological and electrophysiological approaches in vivo, we show that also blocking retinal gap junctions (GJs), which are expressed by multitude of retinal cells, leads to the disruption of oscillatory activity in the rat OPN. Intravitreal injection of carbenoxolone (CBX) quenched oscillations in a concentration-dependent manner with 1mM being ineffective, 5mM showing partial and 20mM showing complete effectiveness in disrupting oscillations. Moreover, the most effective CBX concentration depressed cone-mediated light-induced responses of oscillatory neurons suggesting that CBX is also acting on targets other than GJs. In contrast, intravitreal injection of meclofenamic acid (MFA, 20mM) led to disruption of the rhythm but did not interfere with cone-mediated light-induced responses of oscillatory neurons, implying that MFA is more specific toward GJs than CBX, as suggested before. We conclude that electrical coupling between various types of retinal cells and resultant synchronous firing of retinal ganglion cells is necessary for the generation of infra-slow oscillations in the rat OPN. PMID- 27693815 TI - Congenital prosopagnosia is associated with a genetic variation in the oxytocin receptor (OXTR) gene: An exploratory study. AB - Face-recognition deficits, referred to with the term prosopagnosia (i.e., face blindness), may manifest during development in the absence of any brain injury (from here the term congenital prosopagnosia, CP). It has been estimated that approximately 2.5% of the population is affected by face-processing deficits not depending on brain lesions, and varying a lot in severity. The genetic bases of this disorder are not known. In this study we tested for genetic association between single-nucleotide polymorphisms (SNPs) in the oxytocin receptor gene (OXTR) and CP in a restricted cohort of Italian participants. We found evidence of an association between the common genetic variants rs53576 and rs2254298 OXTR SNPs and prosopagnosia. This association was also found when including an additional group of German individuals classified as prosopagnosic in the analysis. Our preliminary data provide initial support for the involvement of genetic variants of OXTR in a relevant cognitive impairment, whose genetic bases are still largely unexplored. PMID- 27693816 TI - A dynamic, sex-specific expression pattern of genes regulating thyroid hormone action in the developing zebra finch song control system. AB - The zebra finch (Taeniopygia guttata) song control system consists of several series of interconnected brain nuclei that undergo marked changes during ontogeny and sexual development, making it an excellent model to study developmental neuroplasticity. Despite the demonstrated influence of hormones such as sex steroids on this phenomenon, thyroid hormones (THs) - an important factor in neural development and maturation - have not been studied in this regard. We used in situ hybridization to compare the expression of TH transporters, deiodinases and receptors between both sexes during all phases of song development in male zebra finch. Comparisons were made in four song control nuclei: Area X, the lateral magnocellular nucleus of the anterior nidopallium (LMAN), HVC (used as proper name) and the robust nucleus of the arcopallium (RA). Most genes regulating TH action are expressed in these four nuclei at early stages of development. However, while general expression levels decrease with age, the activating enzyme deiodinase type 2 remains highly expressed in Area X, HVC and RA in males, but not in females, until 90days post-hatch (dph), which marks the end of sensorimotor learning. Furthermore, the L-type amino acid transporter 1 and TH receptor beta show elevated expression in male HVC and RA respectively compared to surrounding tissue until adulthood. Differences compared to surrounding tissue and between sexes for the other TH regulators were minor. These developmental changes are accompanied by a strong local increase in vascularization in the male RA between 20 and 30dph but not in Area X or HVC. Our results suggest that local regulation of TH signaling is an important factor in the development of the song control nuclei during the song learning phase and that TH activation by DIO2 is a key player in this process. PMID- 27693817 TI - Role of potassium and pH on the initiation of sperm motility in the European eel. AB - The role of potassium from the seminal plasma and/or the activation media was examined by selectively removing K+ from this media, and by testing the use of K+ channel inhibitors and a K-ionophore. Sperm motility was measured using a CASA system, intracellular K+ and pH were measured by flow cytometry, and sperm head area was measured by ASMA: Automated Sperm Morphometry Analyses. Sperm motility was notably inhibited by the removal of K+ from the seminal plasma and by treatment with the K+ ionophore valinomycin. This therefore indicates that a reduction of K+ levels in the quiescent stage inhibits further motility. The normal decrease in sperm head area induced by seawater activation was altered by the removal of K+ from the seminal plasma, and an increase in the pHi in the quiescent stage was also induced. Intracellular pH (pHi) was quantitatively measured for the first time in European eel spermatozoa, being 7.2 in the quiescent stage and 7.1 post-activation. Intracellular and external pH levels influenced sperm motility both in the quiescent stage and at activation. The alkalinization of the pHi (by NH4Cl) inhibited sperm motility activation, while acidification (by Na-acetate) did not have any effect. Our results indicate that a pH gradient between the sperm cell and the seminal plasma is necessary for sperm motility activation. The presence of the ion K+ in the seminal plasma (or in the extender medium) is necessary in order to maintain sperm volume, intracellular pH and sperm motility. PMID- 27693818 TI - Correlation of Homocysteine with Cerebral Hemodynamic Abnormality, Endothelial Dysfunction Markers, and Cognition Impairment in Patients with Traumatic Brain Injury. AB - OBJECTIVE: This study aimed to assess any correlation between serum levels of homocysteine (Hcy) and markers of cerebral hemodynamics, endothelial dysfunction, and cognition impairment in patients with traumatic brain injury (TBI). METHODS: By a cross-sectional study, all clinical data and serum levels of homocysteine of 85 TBI patients were collected. The pulsatility indices (PIs) of the middle cerebral artery were recorded by transcranial color-coded Doppler ultrasonography and cerebrovascular reactivity was measured by the increase in middle cerebral artery flow velocity in response to 5% inhaled CO2. Serum levels of intercellular adhesion molecule-1 (ICAM-1) and vascular adhesion molecule-1 (VCAM-1), cognition status by Montreal Cognitive Assessment, and Mini-Mental State Examination were measured in all participants. RESULTS: Totally, 85 patients including 51.76% male and the mean age of 54.48 years were studied. The level of Hcy in patients who died in the hospital or during 6 months after TBI was significantly higher than in survivors (P = 0.045, P = 0.020, respectively). Also, the levels of ICAM-1, VCAM-1, and PI in deceased patients were higher than their figures in survivors in both hospital and 6-month follow-ups (P = 0.450, P = 0.000; P = 0.072, P = 0.000, P = 0.090, and P = 0.000, respectively). Cerebrovascular reactivity in deceased patients was significantly lower than that in alive individuals (P = 0.008 and P = 0.000, respectively). A significant correlation was found between Hcy with cognition impairment according to Montreal Cognitive Assessment, Mini Mental State Examination, and cerebral hemodynamic status according to PI (P = 0.000 for all). Also, this correlation was shown between Hcy with ICAM-1 and VCAM 1 in hospital and 6-month follow-ups (P = 0.000 for both). CONCLUSION: Hcy has a significant correlation with markers of cerebrovascular, endothelial, and cognition abnormality in TBI patients. PMID- 27693819 TI - Improving Traumatic Brain Injury Outcomes: The Development of an Evaluation and Referral Tool at Groote Schuur Hospital. AB - BACKGROUND: The Western Cape Province of South Africa has a great shortage of diagnostic expertise, rehabilitative infrastructure, and support services for patients with traumatic brain injury (TBI). The neurosurgical outpatient setting is busy and often chaotic, and patients are frequently lost to follow-up. This study sought to continue with the design and development of a comprehensive, yet brief tool to aid patient referrals and ensure that no consequence of TBI is left unidentified and unaddressed. METHODS: There were 47 patients with TBI (mean age, 35 years; range, 18-75 years) assessed. The study was designed in 3 distinct phases, each representing a different stage in the tool's development. RESULTS: The Groote Schuur Traumatic Brain Injury Evaluation was shortened and simplified. Overall, 81% of the participants indicated cognitive dysfunction. There was a high prevalence of psychological/psychiatric sequelae, with 85% of participants reporting at least 1 such problem. CONCLUSIONS: The findings further highlight the prevalence of the cognitive, behavioral, and psychological consequences of TBI and shed additional light on the particular types of problems that patients with TBI face. Following the identified changes, the questionnaire and algorithm combination are now ready to be validated in the neurosurgical clinical setting. PMID- 27693820 TI - Orbitozygomatic Craniotomy with Modified Zabramski's Technique: A Technical Note and Anatomic and Clinical Findings. AB - BACKGROUND: The surgical technique of orbitozygomatic craniotomy reported by Zabramski et al. is an excellent procedure, facilitating wide surgical exposure, easy orbital reconstruction, and a satisfactory postsurgical aesthetic outcome; however, it is anatomically complicated and technically difficult. We introduce a simplified technique of Zabramski's orbitozygomatic craniotomy and present the anatomic and clinical findings with cadaveric photos, illustrations, and a video. METHODS: The orbitozygomatic craniotomy was performed on 20 sides of 11 cadaveric heads, in which the cut between the inferior orbital fissure and superior orbital fissure was modified and simplified, and the shortest distance between them was measured. This technique was applied to 13 clinical cases, and craniotomy associated aesthetic and functional complications were evaluated. RESULTS: The average of the shortest distance from the inferior orbital fissure to superior orbital fissure was 21.3 mm (range, 19-23 mm) on the 20 sides of the 11 cadaveric heads. In all 13 clinical cases, orbitozygomatic craniotomy could be achieved in a short time, while preserving the structure of the orbital wall. A hollow at the temple was noted in 1 patient, cerebrospinal fluid leak occurred in 2 patients, and transient facial pain occurred in 1 patient; however, no other craniotomy associated aesthetic or functional complications, including enophthalmos, were found in any of the 13 patients. CONCLUSIONS: With this modified technique, Zabramski's ideal orbitozygomatic craniotomy could be achieved easily with only minimal complications, while realizing all advantages of the technique. PMID- 27693821 TI - Post-Traumatic Tremor and Thalamic Deep Brain Stimulation: Evidence for Use of Diffusion Tensor Imaging. AB - BACKGROUND: Deep brain stimulation (DBS) is a well-established treatment to reduce tremor, notably in Parkinson disease. DBS may also be effective in post traumatic tremor, one of the most common movement disorders caused by head injury. However, the cohorts of patients often have multiple lesions that may impact the outcome depending on which fiber tracts are affected. CASE DESCRIPTION: A 20-year-old man presented after road traffic accident with severe closed head injury and polytrauma. Computed tomography scan showed left frontal and basal ganglia hemorrhagic contusions and intraventricular hemorrhage. A disabling tremor evolved in step with motor recovery. Despite high-intensity signals in the intended thalamic target, a visual analysis of the preoperative diffusion tensor imaging revealed preservation of connectivity of the intended target, ventralis oralis posterior thalamic nucleus (VOP). This was confirmed by the postoperative tractography study presented here. DBS of the VOP/zona incerta was performed. Six months postimplant, marked improvement of action (postural, kinetic, and intention) tremor was achieved. CONCLUSIONS: We demonstrated a strong connectivity between the VOP and the superior frontal gyrus containing the premotor cortex and other central brain areas responsible for movement control. In spite of an existing lesion in the target, the preservation of these tracts may be relevant to the improvement of the patient's symptoms by DBS. PMID- 27693822 TI - Flow Diversion for Treatment of Growing A2 Aneurysm in a Child: Case Report and Review of Flow Diversion for Intracranial Aneurysms in Pediatric Patients. AB - BACKGROUND: Intracranial flow diversion has gained increasing popularity since the approval of the Pipeline Embolization Device (PED). Although it is only approved for use in adult patients, the PED has been used to treat aneurysms in pediatric patients. We present the first reported case of the use of a PED in a pediatric patient to treat an unusual fusiform distal anterior cerebral artery aneurysm. CASE DESCRIPTION: A 12-year-old girl presented with new onset seizures and was found to have a distal left anterior cerebral artery aneurysm. Initially, this was managed conservatively, but follow-up imaging performed 4 months after presentation demonstrated enlargement of the aneurysm. The patient underwent endovascular embolization of her aneurysm with PED. This was successfully performed and the patient recovered from the procedure with no neurologic deficits. CONCLUSIONS: Follow-up digital subtraction angiography and magnetic resonance angiography at 6 and 12 months, respectively, showed complete occlusion of the aneurysm. We also reviewed the literature on flow diversion for treatment of pediatric intracranial aneurysms.

AB - Changes in the delivery of the healthcare structure have led to the expansion of the non-medical workforce (NMW). The non-medical practitioner in surgery (a healthcare professional without a medical degree who undertakes specialist training) is a valuable addition to a surgical firm. However, there are a number of challenges regarding the successful widespread implementation of this role. This paper outlines a number of these concerns, and makes recommendations to aid the realisation of the non-medical practitioner as a normal part of the surgical team. In summary, the Association of Surgeons in Training welcomes the development of the non-medical workforce as part of the surgical team in order to promote enhanced patient care and improved surgical training opportunities. However, establishing a workforce of independent/semi-independent practitioners who compete for the same training opportunities as surgeons in training may threaten the UK surgical training system, and therefore the care of our future patients. PMID- 27693824 TI - Advanced vessel sealing devices in total thyroidectomy for substernal goitre: A retrospective cohort study. AB - INTRODUCTION: When total thyroidectomy is performed for substernal goitre, a high risk of morbidity is reported. Advanced vessel sealing devices provide an alternative to the conventional clamp and tie technique. The aim of this study is to compare the outcome of patients who underwent total thyroidectomy for substernal goitre using Ligasure Small Jaw, Harmonic Focus, or conventional technique. METHODS: Between 2011 and 2014, from a population of 393 patients undergoing surgery for thyroid disease, 75 (49 females, 26 males, mean age: 57.9 years; range: 28-83 years) underwent total thyroidectomy by the same surgeon for substernal goitre. Patients were divided into three groups: group A (n = 26) in which total thyroidectomy was performed using conventional technique; group B (n = 22), and group C (n = 27) in which total thyroidectomy was performed using Ligasure Small Jaw and Harmonic Focus, respectively. Operative time, time to drain removal, hospitalization and morbidity (hypoparathyroidism, vocal cord palsy, haemorrhage, seroma, other) were analyzed. RESULTS: Mean duration of surgery was 136.5 +/- 26.7 min in group A vs 110.5 +/- 24.8 in B, and 101.6 +/- 25.4 in C, with significant statistical differences between A vs B (p < 0.005) and C (p < 0.0001). There was no mortality. The overall morbidity was 29.3%. There was no significant difference in time to drain removal, postoperative hospitalization, and morbidity among the three groups. CONCLUSION: This is the first study analyzing advanced vessel sealing devices in total thyroidectomy for substernal goitre in the literature. The use of advanced vessel sealing devices significantly reduces operative time of total thyroidectomy performed for substernal goitre but does not seem to affect the other evaluated outcomes.

AB - OBJECTIVE: To investigate the clinical outcomes of transforaminal endoscopic system(TESSYS) for discogenic low back pain(DLBP). METHODS: 62 consecutive patients with one-level DLBP applying to the including criteria underwent TESSYS from January 2010 to December 2013. These patients included 38 males and 24 females with a mean age of 42.7 +/- 5.4 years (range, 18-73 yr) and a mean follow up of 26.8 +/- 4.2 months (range, 12-48 months). The visual analog scale (VAS) were used for back pain, the Oswestry Disability Index (ODI) for lumbar function, and the modified MacNab criteria for clinical global outcomes. RESULTS: 24 patients showed only inflammatory granuloma on annulus tear tissues(Group A), 16 patients showed no annulus tear but adhesion and inflammatory granuloma among the intracanal annulus fibrous(AF), posterior longitudinal ligament(PLL) and the abdomen side of the dura sac(Group B) and 22 patients showed both(Group C). Concordant pain could be triggered by touching the inflammation with the bipolar radiofrequency probe. The success rate (excellent and good) of group C was much higher than A and B(P < 0.05). The whole success rate was 75.8%. Of the 4 patients with poor result, 2 refused further surgical treatment and showed either no improvement or worsening. The remaining 2 patients had spinal fusion surgery and achieved better results. VAS and ODI had significantly improved after surgery (P < 0.01). No unexpected complications were seen. CONCLUSION: TEEYS is an effective method in treating DLBP and the complete management of the inflammatory granuloma was the key point in achieving better results.

AB - As web technologies and social networks become part of the general public's life, the problem of automatically detecting pornography is into every parent's mind - nobody feels completely safe when their children go online. In this paper, we focus on video-pornography classification, a hard problem in which traditional methods often employ still-image techniques - labeling frames individually prior to a global decision. Frame-based approaches, however, ignore significant cogent information brought by motion. Here, we introduce a space-temporal interest point detector and descriptor called Temporal Robust Features (TRoF). TRoF was custom tailored for efficient (low processing time and memory footprint) and effective (high classification accuracy and low false negative rate) motion description, particularly suited to the task at hand. We aggregate local information extracted by TRoF into a mid-level representation using Fisher Vectors, the state-of-the art model of Bags of Visual Words (BoVW). We evaluate our original strategy, contrasting it both to commercial pornography detection solutions, and to BoVW solutions based upon other space-temporal features from the scientific literature. The performance is assessed using the Pornography-2k dataset, a new challenging pornographic benchmark, comprising 2000 web videos and 140h of video footage. The dataset is also a contribution of this work and is very assorted, including both professional and amateur content, and it depicts several genres of pornography, from cartoon to live action, with diverse behavior and ethnicity. The best approach, based on a dense application of TRoF, yields a classification error reduction of almost 79% when compared to the best commercial classifier. A sparse description relying on TRoF detector is also noteworthy, for yielding a classification error reduction of over 69%, with 19* less memory footprint than the dense solution, and yet can also be implemented to meet real-time requirements. PMID- 27693827 TI - Further investigations into the single metal deposition (SMD II) technique for the detection of latent fingermarks. AB - Single metal deposition (SMD II), a recently proposed method for the development of latent fingermarks, was investigated by systematically altering aspects of the procedure to assess their effect on the level of development and contrast achieved. Gold nanoparticle size, temperature of the deposition solution bath, and orbital shaking during detection were shown to affect the levels of development and contrast obtained. Gold nanoparticles of diameter 15-21nm were found to be most effective for satisfactory visualisation of latent fingermarks, while solutions that were applied at room temperature were found to adequately balance the ratio between the contrast of the fingermark ridge detail and the level of background staining achieved. Finally, optimum levels of development and contrast were obtained through constant agitation of both solution baths at approximately 50RPM throughout the submersion time. SMD II was also tested on a large variety of substrate types and shown to be effective on a range of porous, non-porous, and semi-porous surfaces; however, the detection quality can be significantly influenced by the substrate nature. This resulted in the production of dark grey, white, or gold coloured fingermarks on different surfaces, as well as reversed detection on certain types of plastic, similarly seen through the use of vacuum metal deposition. PMID- 27693828 TI - Ecological effects on arbovirus-mosquito cycles of transmission. AB - Mosquitoes transmit many viruses to a variety of hosts. Cycles of mosquito borne arbovirus transmission are the result of complex interactions between the mosquito, the arbovirus and the host that are influenced by genetic variations in a variety of traits in each that are all influenced by many environmental factors. R0, the basic reproduction number or mean number of individuals infected from a single infected individual, is a measure of mosquito borne arbovirus transmission. Understanding the causes for the distribution of R0 in any transmission cycle is a daunting challenge due to the lack of information on the genetic and environmental variances that influence R0. Information about the major factors influencing R0 for specific transmission cycles is essential to develop efficient and effective strategies to reduce transmission in different cycles and locations. PMID- 27693829 TI - Extinction and renewal of cue-elicited reward-seeking. AB - Reward cues can contribute to overconsumption of food and drugs and can relapse. The failure of exposure therapies to reduce overconsumption and relapse is generally attributed to the context-specificity of extinction. However, no previous study has examined whether cue-elicited reward-seeking (as opposed to cue-reactivity) is sensitive to context renewal. We tested this possibility in 160 healthy volunteers using a Pavlovian-instrumental transfer (PIT) design involving voluntary responding for a high value natural reward (chocolate). One reward cue underwent Pavlovian extinction in the same (Group AAA) or different context (Group ABA) to all other phases. This cue was compared with a second non extinguished reward cue and an unpaired control cue. There was a significant overall PIT effect with both reward cues eliciting reward-seeking on test relative to the unpaired cue. Pavlovian extinction substantially reduced this effect, with the extinguished reward cue eliciting less reward-seeking than the non-extinguished reward cue. Most interestingly, extinction of cue-elicited reward-seeking was sensitive to renewal, with extinction less effective for reducing PIT when conducted in a different context. These findings have important implications for extinction-based interventions for reducing maladaptive reward seeking in practice.

AB - The secretory granule of the pancreatic beta-cells is a zinc-rich environment copopulated with the hormones amylin and insulin. The human amylin is shown to interact with zinc ions with major contribution from the single histidine residue, which is absent in amylin from other species such as cat, rhesus and rodents. We report here the interaction of murine amylin with zinc ions in vitro. The self-assembly of murine amylin is tightly regulated by zinc and pH. Ion mobility mass spectrometry revealed zinc interaction with monomers and oligomers. Nuclear magnetic resonance confirms the binding of zinc to murine amylin. The aggregation process of murine amylin into amyloid fibrils is accelerated by zinc. Collectively these data suggest a general role of zinc in the modulation of amylin variants oligomerization and amyloid fibril formation. PMID- 27693832 TI - Thermal, emulsifying and rheological properties of polysaccharides sequentially extracted from Vaccinium bracteatum Thunb leaves. AB - Plant polysaccharides are widely used in food industry as thickening and gelling agents and these attributes largely depend on their thermal, emulsifying and rheological properties. As known, the extraction methods always bring about the diversification of property and functions of polysaccharides. Thus, the Vaccinium bracteatum Thunb leaves polysaccharides (VBTLP) were sequentially extracted using hot buffer (HBSS), chelating agent (CHSS), dilute alkaline (DASS) and concentrated alkaline (CASS). The thermal, emulsifying and rheological properties of VBTLP were investigated in the present study. Within the range of 20-225 degrees C, CHSS showed the highest peak temperature, whereas HBSS displayed the highest endothermic enthalpy and highest emulsifying activity, while, CASS showed the longest emulsifying stability. The VBTLP solutions exhibited non-Newtonian shear-thinning behavior within the concentrations of 0.6-2.5%. The apparent viscosity of VBTLP solution decreased under following conditions: acidic pH (4.0), alkaline pH (10.0), in the presence of Ca2+ and at high temperature, while it increased in the presence of Na+ and at freezing conditions. The modulus G' and G" of VBTLP solutions were increased with increasing oscillation frequency, and the crossover frequency shifted to lower values when the polysaccharide content increased. The above results of thermal, emulsifying and rheological properties of VBTLPs supplied the basis for V. bracteatum leaves in potential industrial applications of foods. PMID- 27693833 TI - Monosaccharide composition of acidic gum exudates from Indian Acacia tortilis ssp. raddiana (Savi) Brenan. AB - Acacia tortilis ssp. raddiana (Savi) Brenan commonly known as Israeli Babool has contributed immensely for sand dunes management in Indian desert leading to wind erosion control and increased biological productivity. The species is extensively used in traditional medicine system for a number of therapeutic applications and as nutraceutical. The polysaccharide was isolated in 43.6% yield from gum exudates. The monosaccharides, L-arabinose, D-galactose D-glucose, L-rhamnose and D-mannose were determined in molar ratio of 78.1%, 18.64%, 0.60%, 1.71% and 0.74% respectively. The molar ratio of uronic acids was studied using diverse spectrophotometric methods and compared with GLC. The content of D-galacturonic acid and D-glucuronic was determined as 3.88% and 4.35% respectively by GLC. The results were compared with the spectrophotometric methods. The results using DMP as chromogenic reagent are closer to that obtained by GLC. Structural analysis of the polysaccharide may provide scientific basis for nutraceutical, pharmaceutical and biological applications of gum exudates from A. tortilis, which is extensively planted in India. PMID- 27693830 TI - Nutrition and other lifestyle influences on arterial aging. AB - As our world's population ages, cardiovascular diseases (CVD) will become an increasingly urgent public health problem. A key antecedent to clinical CVD and many other chronic disorders of aging is age-related arterial dysfunction, characterized by increased arterial stiffness and impaired arterial endothelial function. Accumulating evidence demonstrates that diet and nutrition may favorably modulate these arterial functions with aging, but many important questions remain. In this review, we will summarize the available information on dietary patterns and nutritional factors that have been studied for their potential to reduce arterial stiffness and improve endothelial function with age, with an emphasis on: 1) underlying physiological mechanisms, and 2) emerging areas of research on nutrition and arterial aging that may hold promise for preventing age-related CVD. PMID- 27693835 TI - Structural elucidation of anti-metastatic rhamnogalacturonan II from the pectinase digest of citrus peels (Citrus unshiu). AB - The aim of this study was to characterize a polysaccharide found in citrus peels with an anti-metastatic property. CPE-II was purified by the pectinase digestion of citrus peels. During in vivo lung metastasis of Colon26-M3.1, administration of 10MUg of CPE-II per mouse showed 81.3% inhibition of metastasis. CPE-II consists of 15 different monosaccharides and 22 different glycosyl linkages, characteristic of rhamnogalacturonan II (RG-II). The primary structure was elucidated based on sugar composition, methylation analysis, oligosaccharide analysis, and sequencing using GC, GC-MS, LC-MS, and ESI-MS/MS analyses. Sequential degradation using partial acid hydrolysis indicated that CPE-II contained Rhap-(1->5)-Kdo, Araf-(1->5)-Dha, an AceA-containing nonasaccharide, and an uronic acid-rich oligosaccharide in addition to an alpha-(1->4) galacturono-oligosaccharide main chain. The molecular weight of CPE-II was observed to decrease from 9 to 5kDa at a pH value of <2.0, as observed by HPSEC. Thus, we propose that the anti-metastatic CPE-II is primarily present as an RG-II dimer. PMID- 27693834 TI - Effects of polysaccharide from mycelia of Ganoderma lucidum on intestinal barrier functions of rats. AB - The intestinal mucosal barriers play essential roles not only in the digestion and absorption of nutrients, but also the innate defense against most intestinal pathogens. In the present study, polysaccharide from the mycelia of Ganoderma lucidum was given via oral administration to rats (100mg/kg body weight, 21days) to investigate its effects on intestinal barrier functions, including the mechanical barrier, immunological barrier and biological barrier function. It was found that the polysaccharide administration could significantly up-regulate the expression of occludin, nuclear factor-kappaB p65 (NF-kappaB p65) and secretory immunoglobulin A (SIgA) in ileum, markedly improve the levels of interferon-gamma (IFN-gamma), interleukin-2 (IL-2), and IL-4, and decrease the level of diamine oxidase (DAO) in serum. Meanwhile, rats from the polysaccharide group showed significant higher microbiota richness in cecum as reflected by the Chao 1 index compared with the control group. Moreover, the polysaccharide decreased the Firmicutes-to-Bacteroidetes ratio. Our results indicated that the polysaccharide from the mycelia of G. lucidum might be used as functional agent to regulate the intestinal barrier functions. PMID- 27693836 TI - The effect of a patient centred care bundle intervention on pressure ulcer incidence (INTACT): A cluster randomised trial. AB - BACKGROUND: Hospital-acquired pressure ulcers are a serious patient safety concern, associated with poor patient outcomes and high healthcare costs. They are also viewed as an indicator of nursing care quality. OBJECTIVE: To evaluate the effectiveness of a pressure ulcer prevention care bundle in preventing hospital-acquired pressure ulcers among at risk patients. DESIGN: Pragmatic cluster randomised trial. SETTING: Eight tertiary referral hospitals with >200 beds each in three Australian states. PARTICIPANTS: 1600 patients (200/hospital) were recruited. Patients were eligible if they were: >=18 years old; at risk of pressure ulcer because of limited mobility; expected to stay in hospital >=48h and able to read English. METHODS: Hospitals (clusters) were stratified in two groups by recent pressure ulcer rates and randomised within strata to either a pressure ulcer prevention care bundle or standard care. The care bundle was theoretically and empirically based on patient participation and clinical practice guidelines. It was multi-component, with three messages for patients' participation in pressure ulcer prevention care: keep moving; look after your skin; and eat a healthy diet. Training aids for patients included a DVD, brochure and poster. Nurses in intervention hospitals were trained in partnering with patients in their pressure ulcer prevention care. The statistician, recruiters, and outcome assessors were blinded to group allocation and interventionists blinded to the study hypotheses, tested at both the cluster and patient level. The primary outcome, incidence of hospital-acquired pressure ulcers, which applied to both the cluster and individual participant level, was measured by daily skin inspection. RESULTS: Four clusters were randomised to each group and 799 patients per group analysed. The intraclass correlation coefficient was 0.035. After adjusting for clustering and pre-specified covariates (age, pressure ulcer present at baseline, body mass index, reason for admission, residence and number of comorbidities on admission), the hazard ratio for new pressure ulcers developed (pressure ulcer prevention care bundle relative to standard care) was 0.58 (95% CI: 0.25, 1.33; p=0.198). No adverse events or harms were reported. CONCLUSIONS: Although the pressure ulcer prevention care bundle was associated with a large reduction in the hazard of ulceration, there was a high degree of uncertainty around this estimate and the difference was not statistically significant. Possible explanations for this non-significant finding include that the pressure ulcer prevention care bundle was effective but the sample size too small to detect this. PMID- 27693837 TI - Massive upper gastrointestinal bleeding due to splenoportal axis thrombosis in a patient with a tested JAK2 mutation: A case report and review literature. AB - Portal hypertension is a clinical syndrome defined as a portal venous pressure that exceeds 10mmHg. Cirrhosis is the most common cause of portal hypertension and thrombosis of the splenoportal axis not associated with liver cirrhosis is the second cause of portal hypertension in the Western world. The primary myeloproliferative disorders are the main cause of portal venous thrombosis and somatic mutation of Janus Kinase 2 gene (JAK2 V617F) can be found in approximately 90% of polycythemia vera, 50% of essential thrombocyrosis and 50% primary myelofibrosis. A a 55-year-old man with JAK2 mutation-associated splenoportal axis hypertension and bleeding complications due to oesophageal varices is reported. A massive upper bleeding episode made an emergent surgery to be done immediatelly at seventh day. The patient was discharged home at fifteenth day after surgery. PMID- 27693838 TI - Pure small cell carcinoma of the prostate preceded by acute zonal occult outer retinopathy: A case report. AB - INTRODUCTION: Pure small cell prostate cancer (SCPC) cases are very rare. Acute zonal occult outer retinopathy (AZOOR) has been described as a non-neoplastic retinopathy. We report the first case of pure SCPC preceded by AZOOR in the literature. CASE REPORT: A 59year old gentleman presented with an obstructed infected urinary system. He had a diagnosis of AZOOR 6 months ago that was investigated with full body imaging without any suspicious findings. However, the most recent CT findings demonstrated extensive disease dissemination. The patient underwent rigid cystoscopy and resection that confirmed a diagnosis of pure SCPC. DISCUSSION: AZOOR is a clinical syndrome of photopsia and rapid zonal field loss. The exact aetiology remains unknown and its association with malignancy remains contentious. Paraneoplastic manifestations of unexplained visual loss in SCPC are rare with only 2 cases reported in the literature. There are no cases demonstrating an association between AZOOR and SCPC. CONCLUSION: Pure SCPC is an aggressive malignancy with most cases presenting with extensive disease dissemination on diagnosis. Early detection has a role in improving prognosis but is challenging. Further research is required to establish a standard treatment protocol. PMID- 27693839 TI - Intravenous vs intraperitoneal transplantation of umbilical cord mesenchymal stem cells from Wharton's jelly in the treatment of streptozotocin-induced diabetic rats. AB - AIM: To evaluate the efficiency of mesenchymal stem cells isolated from Wharton's jelly (WJ-MSCs) through either the intravenous or intraperitoneal transplantations into streptozotocin (STZ)-induced diabetic rats as a therapy for type 1 diabetes mellitus (T1DM). METHODOLOGY: A rat model with STZ induction was established and the rats were divided into 3 groups: a tail vein injection group, an intraperitoneal injection group and a STZ control group. Following transplantation, blood glucose levels were monitored weekly then the pancreatic tissues were collected to examine the pancreatic islets by histopathology and morphometric studies. RESULTS: Intravenous transplantation of WJ-MSCs ameliorated hyperglycemia at day 7 after transplantation, with sustained decreased fasting blood glucose (FBG) levels until day 56. Further, these cells ameliorated at least partially the damage induced by STZ in the pancreas and produced a similar morphology to normal islets. On the contrary, intraperitoneal transplantation of WJ-MSCs failed to maintain normoglycemia or ameliorate the damaged pancreas in STZ-injected rats. CONCLUSION: These findings conclude that the intravenous administration method was effective in transplanting WJ-MSCs for the treatment of T1DM, whereas the intraperitoneal transplantation showed no therapeutic effect in our animal experiments. PMID- 27693841 TI - Gardenia jasminoides extract-capped gold nanoparticles reverse hydrogen peroxide induced premature senescence. AB - This study reports a green approach for synthesis of gold nanoparticles using Gardenia jasminoides extract, and specifically, can potentially enhance anti senescence activity. Biological synthesis of gold nanoparticles is ecofriendly and effective for the development of environmentally sustainable nanoparticles compared with existing methods. Here, we developed a simple, fast, efficient, and ecofriendly approach to the synthesis of gold nanoparticles by means of a Gardenia jasminoides extract. These G. jasminoides extract-capped gold nanoparticles (GJ-GNPs) were characterized by UV-vis, high resolution transmission electron microscopy (HR-TEM), X-ray diffraction (XRD), and Furrier transform infrared spectroscopy (FT-IR). The synthesized GJ-GNPs turned red and showed maximal absorbance at 540nm. Thus, GJ-GNPs were synthesized successfully. We hypothesized that GJ-GNPs would protect ARPE19 cells from hydrogen peroxide induced premature senescence. SA-beta-gal activity was elevated in hydrogen peroxide-treated cells, however, this effect was attenuated by GJ-GNP treatment. Moreover, compared with the normal control, hydrogen peroxide treatment significantly increased lysosome content of the cells and production of reactive oxygen species (ROS). GJ-GNPs effectively attenuated the increase in lysosome content and ROS production in these senescent cells. According to cell cycle analysis, G2/M arrest was promoted by hydrogen peroxide treatment in ARPE19 cells, however, this change was reversed by GJ-GNPs. Western blot analysis showed that treatment with GJ-GNPs increased the expression of p53, p21, SIRT3, HO-1, and NQO1 in senescent cells. Our findings should advance the understanding of premature senescence and may lead to therapeutic use of GJ-GNPs in retina-related regenerative medicine. PMID- 27693840 TI - Clinical predictors differentiating non-diabetic renal diseases from diabetic nephropathy in a large population of type 2 diabetes patients. AB - AIMS: Non-diabetic renal diseases (NDRDs) are associated with better renal outcomes than diabetic nephropathy (DN). This study was conducted to determine the common clinical markers predicting NDRDs in type 2 diabetes patients. METHODS: Patients with type 2 diabetes mellitus who underwent a renal biopsy were screened. Eligible patients were categorized into two groups: DN group and NDRD group. Patient's clinical characteristics and laboratory data were collected. Logistic regression analysis was performed to identify risk factors for NDRD development, and the diagnostic performance of these variables was evaluated. RESULTS: The study included 248 patients, 96 (38.71%) in the DN group and 152 (61.29%) in the NDRD group. Patients in the NDRD group had a shorter duration of DM and higher hemoglobin, estimated glomerular filtration rate, and urine osmotic pressure values as well as a higher incidence of glomerular hematuria than patients in the DN group. In the NDRD patients, the most common pathological type was membranous nephropathy (55, 36.18%). Absence of retinopathy (OR, 44.696, 95% CI, 15.91-125.566), glomerular hematuria (OR, 9.587, 95% CI, 2.027-45.333), and DM history ?5years (OR, 4.636, 95% CI, 1.721-12.486) were significant and independent risk factors for the development of NDRD (P<0.01). Absence of retinopathy achieved the overall highest diagnostic efficiency with a sensitivity of 92.11% and specificity of 82.29%. Glomerular hematuria had the highest specificity (93.75%). CONCLUSION: Shorter duration of diabetes (?5years), absence of retinopathy, and presence of glomerular hematuria were independent indicators associated with NDRDs, indicating the need for renal biopsy. PMID- 27693842 TI - New insights into the dimerization and site-specific cooperative interaction of Azure B with model transport proteins by spectroscopic and computational studies. AB - In the present study, the interaction of model transport proteins Human serum albumin (HSA) and Bovine serum albumin (BSA) with a photoactive dye, Azure B (AZB) were studied by spectroscopic and in silico methods. The absorption spectral behavior of AZB in the presence of varying concentrations of serum albumins (HSA and BSA) revealed the formation of dye aggregates within the protein cavity. The binding parameters computed from the emission quenching data showed that AZB bind to HSA and BSA with significant affinity and it was revealed that both the serum proteins (HSA and BSA) can bind AZB at more than one binding sites having at least one high-affinity binding site with different affinities (non-independent). The existence of static quenching mechanism was further evidenced from the time-resolved fluorescence spectroscopic analysis. Site competitive replacement experiments with specific site markers showed that AZB binds to site I of HSA and BSA. AutoDock based blind docking approach and molecular dynamics simulation studies were used to analyze the most probable binding location of AZB in HSA and BSA. The AZB induced unfolding of HSA and BSA was established by using absorption, circular dichroism and FT-IR spectral studies. The influence of AZB complexation on the biological function of HSA and BSA was evaluated by probing the hydrolysis of p-nitrophenyl acetate. PMID- 27693843 TI - Degradation of tyrosine and tryptophan residues of peptides by type I photosensitized oxidation. AB - Pterin derivatives are involved in various biological functions, including enzymatic processes that take place in human skin. Unconjugated oxidized pterins are efficient photosensitizers under UV-A irradiation and accumulate in the skin of patients suffering from vitiligo, a chronic depigmentation disorder. These compounds are able to photoinduce the oxidation of the peptide alpha-melanocyte stimulating hormone (alpha-MSH), which stimulates the production and release of melanin by melanocytes in skin and hair. In the present work we have used two peptides in which the amino acid sequence of alpha-MSH was mutated to specifically investigate the reactivity of tryptophan (Trp) and tyrosine residues (Tyr). The parent compound of oxidized pterins (Ptr) was used as a model photosensitizer in aqueous solution at pH5.5 and was exposed to UV-A radiation, a wavelength range where the peptides do not absorb. Trp residue yields N formylkynurenine and hydroxytryptophan as oxidized products, whereas the Tyr undergoes dimerization and incorporation of oxygen atoms. In both cases, the first step of the mechanism involves an electron transfer from the amino acid to the photosensitizer triplet excited state, Ptr is not consumed and hydrogen peroxide (H2O2) is released. The role of singlet oxygen produced by energy transfer from 3Ptr* to dissolved O2 was negligible or minor. Other amino acid residues, such as histidine, might be also affected. PMID- 27693844 TI - Trehalose protects Mn-depleted photosystem 2 preparations against the donor-side photoinhibition. AB - Recently, it has been shown that the addition of 1M trehalose leads to the increase of the rate of oxygen photoconsumption associated with activation of electron transport in the reaction center of photosystem 2 (PS2) in Mn-depleted PS2 membranes (apo-WOC-PS2) [37]. In the present work the effect of trehalose on photoinhibition of apo-WOC-PS2 preparations (which are characterized by a high sensitivity to the donor side photoinhibition of PS2) was investigated. The degree of photoinhibition was estimated by the loss of the capability of exogenous electron donor (sodium ascorbate) to reactivate the electron transport (measured by light-induced changes of chlorophyll fluorescence yield (?F)) in apo WOC-PS2. It was found that 1M trehalose enhanced the Mn2+-dependent suppression of photoinhibition of apo-WOC-PS2: in the presence of trehalose the addition of 0.2MUM Mn2+ (corresponding to 2 Mn2+ per one reaction center) was sufficient for an almost complete suppression of the donor side photoinhibition of the complex. In the absence of trehalose it was necessary to add 100MUM Mn2+ to achieve a similar result. The effect of trehalose was observed during photoinhibition of apo-WOC-PS2 at low (15MUmolphotons-1m-2) and high (200MUmolphotons-1m-2) light intensity. When Mn2+ was replaced by other PS2 electron donors (ferrocyanide, DPC) as well as by Ca2+ the protective effect of trehalose was not observed. It was also found that 1M trehalose decreased photoinhibition of apo-WOC-PS2 if the samples contained endogenous manganese (1-2 Mn ions per one RC was enough for the maximum protection effect). It is concluded that structural changes in PS2 caused by the addition of trehalose enhance the capability of photochemical reaction centers of apo-WOC-PS2 to accept electrons from manganese (both exogenous and endogenous), which in turn leads to a considerable suppression of the donor side photoinhibition of PS2. PMID- 27693845 TI - Anti-inflammatory and anti-fibrinolytic effects of thrombomodulin alfa through carboxypeptidase B2 in the presence of thrombin. AB - BACKGROUND: Thrombomodulin (TM) alfa, a recombinant human soluble TM, enhances activation of pro-carboxypeptidase B2 (pro-CPB2) by thrombin. Activated pro-CPB2 (CPB2) exerts anti-inflammatory and anti-fibrinolytic activities. Therefore, TM alfa may also have anti-inflammatory and anti-fibrinolytic effects through CPB2. However, these effects of TM alfa have not been elucidated. In the present study, we investigated the effects of TM alfa on inactivation of complement component C5a as an anti-inflammatory effect and prolongation of clot lysis time as an anti fibrinolytic effect via CPB2 in vitro. METHODS: CPB2 activity and tissue factor induced thrombin generation was examined by a chromogenic assay. C5a inactivation was evaluated by C-terminal cleavage of C5a and inhibition of C5a-induced human neutrophil migration. Clot lysis time prolongation was examined by a tissue-type plasminogen activator-induced clot lysis assay. RESULTS: CPB2 activity in human plasma was increased by TM alfa and thrombin in a concentration-dependent manner. TM alfa inhibited tissue factor-induced thrombin generation and enhanced pro-CPB2 activation in human plasma simultaneously. The mass spectrum of C5a treated with TM alfa, thrombin, and pro-CPB2 was decreased at 156m/z, indicating that TM alfa enhanced the processing of C5a to C-terminal-cleaved C5a, an inactive form of C5a. C5a-induced human neutrophil migration was decreased after C5a treatment with TM alfa, thrombin, and pro-CPB2. TM alfa prolonged the clot lysis time in human plasma, and this effect was completely abolished by addition of a CPB2 inhibitor. CONCLUSIONS: TM alfa exerts anti-inflammatory and anti-fibrinolytic effects through CPB2 in the presence of thrombin in vitro.

A number of research groups have suggested changes in the volume and/or function of the striatum as a causal agent. Two recent studies in children and one in adults who stutter (AWS) report differences in striatal volume compared that seen in controls; however, the laterality and nature of this anatomical volume difference is not consistent across studies. The current study investigated whether a reduction in striatal grey matter volume, comparable to that seen in children who stutter (CWS), would be found in AWS. Such a finding would support claims that an anatomical striatal anomaly plays a causal role in stuttering. We used voxel-based morphometry to examine the structure of the striatum in a group of AWS and compared it to that in a group of matched adult control subjects. Results showed a statistically significant group difference for the left caudate nucleus, with smaller mean volume in the group of AWS. The caudate nucleus, one of three main structures within the striatum, is thought to be critical for the planning and modulation of movement sequencing. The difference in striatal volume found here aligns with theoretical accounts of stuttering, which suggest it is a motor control disorder that arises from deficient articulatory movement selection and sequencing. Whilst the current study provides further evidence of a striatal volume difference in stuttering at the group level compared to controls, the significant overlap between AWS and controls suggests this difference is unlikely to be diagnostic of stuttering.

AB - Lentinan (LNT) is an immune regulator and its potential and mechanism for the treatment of mood disorder is of our interest. Dectin-1 is a beta-glucan (including LNT) receptor that regulates immune functions in many immune cell types. Cumulative evidence has suggested that the glutamatergic system seems to play an important role in the treatment of depression. Here, we studied the antidepressant-like effects of LNT and its therapeutical target in regulating the functions of AMPA receptors. We found that 60min treatment with LNT leads to a significant antidepressant-like effect in the tail suspension test (TST) and the forced swim test (FST) in mice. The antidepressant-like effects of LNT in TST and FST remained after 1day or 5days of injections. Additionally, LNT did not show a hyperactive effect in the open field test. Dectin-1 receptor levels were increased after LNT treatment for 5days and the specific Dectin-1 inhibitor laminarin was able to block the antidepressant-like effects of LNT. After 5days of treatment, LNT enhanced p-GluR1 (S845) in the prefrontal cortex (PFC); however, the total GluR1, GluR2, and GluR3 expression levels remained unchanged. We also found that the AMPA-specific blocker GYKI 52466 was able to block the antidepressant-like effects of LNT. This study identified LNT as a novel antidepressant with clinical potential and a new antidepressant mechanism for regulating prefrontal Dectin-1/AMPA receptor signaling. PMID- 27693848 TI - Kynurenine 3-monooxygenase is implicated in antidepressants-responsive depressive like behaviors and monoaminergic dysfunctions. AB - l-Tryptophan (TRP) is metabolized via serotonin and kynurenine pathways (KP). Several studies have demonstrated that abnormality of both pathways is involved in the pathogenesis of major depressive disorder (MDD). Kynurenine 3 monooxygenase (KMO), a pivotal enzyme in the KP, has been suggested to play major roles in physiological and pathological events mediated by bioactive kynurenine metabolites. In this study, we investigated the role of KMO in the emotional and cognitive functions by using KMO knockout (KO) mice. We measured contents of TRP and monoamines and their metabolites in the serum and hippocampus of KMO KO mice. Further, we investigated whether antidepressants improved the depressive-like behaviors in KMO KO mice. KMO KO mice showed depressive-like behaviors such as decreased sucrose preference and increased immobility in the forced swimming test and high anxiety by decreased time spent in the center area of open field. But, there was no difference in spontaneous alternation in Y-maze test, counts of rearing or locomotor activity. Higher contents of TRP metabolites such as kynurenine (KYN), kynurenic acid (KA), anthranilic acid (AA), and 3 hydroxykynurenine (3-HK) in the serum and hippocampus and decreased serotonin turnover and higher content of normetanephrine (NM) in the hippocampus were observed in the KMO KO mice. Although both antidepressant attenuated increase of immobility, sertraline but not imipramine improved decrease of sucrose preference in the KMO KO mice. These findings suggested that KMO KO mice show antidepressants-responsive depressive-like behaviors and monoaminergic dysfunctions via abnormality of kynurenine metabolism with good validities as MDD model.

AB - Graph theory applications had spread widely in understanding how human cognitive functions are linked to dynamics of neuronal network structure, providing a conceptual frame that can reduce the analytical brain complexity. This review summarizes methodological advances in this field. Electroencephalographic functional network studies in pathophysiological aging will be presented, focusing on neurodegenerative disease -such Alzheimer's disease-aiming to discuss whether network science is changing the traditional concept of brain disease and how network topology knowledge could help in modeling resilience and vulnerability of diseases. Aim of this work is to open discussion on how network model could better describe brain architecture. PMID- 27693850 TI - Selective amotivation deficits following chronic psychosocial stress in mice. AB - Amotivation is a major symptom of several psychiatric disorders. However, which specific motivations are most affected in various illnesses is not well understood. In major depressive disorder (MDD), anecdotal evidence suggests the motivation to explore may be especially affected, but direct evidence from either patients or animal models is lacking. To investigate the potential for, and nature of, exploratory drive deficits in MDD, we subjected mice to a chronic social defeat (CSD) manipulation that gives rise to a MDD-like behavioural ensemble, and performed a behavioural battery to examine bodyweight homeostasis, ambulation, anxiety, exploratory behaviour motivated by either novelty or fear, and short-term memory. Consistent with previous reports, we found a disruption of bodyweight homeostasis and reduced ambulation following CSD treatment, but we found no evidence for anxiogenic effects or impairments in short-term memory. Surprisingly, we also observed profoundly delayed and diminished exploration of novel, safe space following CSD, while exploration motivated by fear remained intact. These results extend our knowledge of the behavioural phenotypes in mice resulting from CSD by homing in on specific motivational drives. In MDD patients, reduced exploration could compound disease symptomatology by preventing engagement in what could be rewarding exploration experiences, and targeting deficits in the motivation to explore may represent a novel avenue for treatment. PMID- 27693851 TI - Behavioral facilitation after hippocampal lesion: A review. AB - When parts of the brain suffer from damage, certain functional deficits or impairments are the expected and typical outcome. A myriad of examples show such negative consequences, which afford the daily tasks of neurologists, neuropsychologists, and also behavioral neuroscientists working with experimental brain lesions. Compared to lesion-induced deficits, examples for functional enhancements or facilitation after brain lesions are rather rare and usually not well studied. Here, the mammalian hippocampus seems to provide an exception, since substantial evidence shows that its damage can have facilitatory behavioral effects under certain conditions. This review will address these effects and their possible mechanisms. It will show that facilitatory effects of hippocampal lesions, although mostly studied in rats, can be found in many mammalian species, that is, they are apparently not species-specific. Furthermore, they can be found with various lesion techniques, from tissue ablation, to neurotoxic damage, and from damage of hippocampal structure itself to damage of fiber systems innervating it. The major emphasis of this review, however, lies on the behavioral effects and their interpretations. Thus, facilitatory effects can be found in several learning paradigms, especially active avoidance, and some forms of Pavlovian and instrumental conditioning. These will be discussed in light of pertinent theories of hippocampal function, such as inhibition, spatial cognition, and multiple memory systems theories, which state that facilitatory effects of hippocampal lesions may reflect the loss of interference between hippocampal spatial and striatal procedural cognition. Using the example of the rat sequential reaction time task, it will also be discussed how such lesions can have direct and indirect consequences on certain behavioral readouts. A final note will advocate considering possible functional facilitation also in neurologic patients, especially those with hippocampal damage, since such a strategy might provide new avenues for therapeutic treatments. PMID- 27693852 TI - Chronic post-traumatic stress disorder-related traits in a rat model of low-level blast exposure. AB - The postconcussion syndrome following mild traumatic brain injuries (mTBI) has been regarded as a mostly benign syndrome that typically resolves in the immediate months following injury. However, in some individuals, symptoms become chronic and persistent. This has been a striking feature of the mostly blast related mTBIs that have been seen in veterans returning from the recent conflicts in Iraq and Afghanistan. In these veterans a chronic syndrome with features of both the postconcussion syndrome and post-traumatic stress disorder has been prominent. Animal modeling of blast-related TBI has developed rapidly over the last decade leading to advances in the understanding of blast pathophysiology. However, most studies have focused on acute to subacute effects of blast on the nervous system and have typically studied higher intensity blast exposures with energies more comparable to that involved in human moderate to severe TBI. Fewer animal studies have addressed the chronic effects of lower level blast exposures that are more comparable to those involved in human mTBI or subclinical blast. Here we describe a rat model of repetitive low-level blast exposure that induces a variety of anxiety and PTSD-related behavioral traits including exaggerated fear responses that were present when animals were tested between 28 and 35 weeks after the last blast exposure. These animals provide a model to study the chronic and persistent behavioral effects of blast including the relationship of PTSD to mTBI in dual diagnosis veterans. PMID- 27693853 TI - Melatonin and cortisol profiles in the absence of light perception. AB - As light plays an important role in the synchronisation of the internal biological clock to the environmental day/night schedule, we compared the 24-h profiles of biological circadian markers in blind and normal sighted individuals. Salivary melatonin and cortisol concentrations were collected every two hours in eleven blind subjects, reporting no conscious light perception, and eleven age- and sex-matched normal sighted controls. Timing of melatonin onset and associated cortisol quiescence period confirm an increased incidence of abnormal circadian patterns in blindness. Additionally, blind subjects showed a greater overall melatonin concentration throughout the 24-h period. Cortisol profiles, including concentration and morning cortisol peaks, on the other hand, did not differ between blind and sighted individuals. These findings support previous reports of an increase in abnormal circadian rhythms and the absence of the entrainment properties of light in blindness. PMID- 27693854 TI - The impact of trauma on the onset of mental health symptoms, aggression, and criminal behavior in an inpatient psychiatric sample. AB - Experiences of trauma and maltreatment are frequent predictors of poor physical and mental health outcomes in adulthood. Existing literature also suggests an impact of developmental adversity on criminality and aggressive behavior, though little research exists describing the effects of cumulative adversity in forensic mental health samples. In the current study of 381 forensic mental health inpatients, rates of trauma, neglect, and parental substance abuse are reported in comparison with community norms. Cumulative adversity and the occurrence of foster care placement are examined via linear and logistic regression analyses in relation to age at first arrest, first psychiatric hospitalization, and onset of aggression, as well as history of suicide attempts and non-suicidal self-injury. Results revealed that experiences of developmental adversity were more common among participants than have been reported in community samples using the ACE survey, and that there were differential effects of gender on the prevalence of traumas experienced. Cumulative adversity scores were significantly associated with all outcomes, though the addition of foster care placement to the model significantly contributed to understanding outcomes, and in some cases, removed the effect of cumulative adversity. Implications and direction for future study are discussed. PMID- 27693855 TI - TP53-induced glycolysis and apoptosis regulator protects from spontaneous apoptosis and predicts poor prognosis in chronic lymphocytic leukemia. AB - OBJECTIVES: Circulating chronic lymphocytic leukemia (CLL) cells appear not to be overly utilizing aerobic glycolysis. However, recurrent contact with CLL cells in a stromal microenvironment leads to increased aerobic glycolysis and the cells' overall glycolytic capacity, which promotes cell survival and proliferation. TP53 induced glycolysis and apoptosis regulator (TIGAR) has been directly implicated in cellular metabolism in the control of glycolysis. TIGAR inhibits glycolysis and protects cells from intracellular reactive oxygen species (ROS)-associated apoptosis. METHODS: TIGAR mRNA expression was investigated by quantitative PCR in 102 newly diagnosed CLL patients. Furthermore, the relationship between the expression of TIGAR and its clinical characteristics and prognosis were investigated. Moreover, we also investigated the correlation between TIGAR expression and apoptosis in primary CLL cells. RESULTS: Our data revealed that TIGAR overexpression was correlated with the protection from spontaneous apoptosis in CLL cells, and is strongly associated with advanced Binet stage, unmutated immunoglobulin heavy-chain variable region (IGHV) status, CD38 positivity, beta2-microglobulin and p53 aberrations. Higher expression of TIGAR was associated with shorter treatment-free survival (median: three months vs. 51 months, P=0.0108), worse overall survival (median: 74 months vs. not reached, P=0.0242), and the diverse responses to fludarabine-based chemotherapy. TIGAR expression in patients resistant to chemotherapy was significantly higher than in patients sensitive to chemotherapy (mean: 0.3859+/-0.1710 vs. 0.0974+/-0.0291, P=0.0290). CONCLUSION: Taken together, our findings revealed that high TIGAR expression is closely correlated with worse clinical outcome in CLL patients, and depicted how bioenergetic characteristics could be therapeutically exploited in CLL. PMID- 27693856 TI - Gradient-dependent release of the model drug TRITC-dextran from FITC-labeled BSA hydrogel nanocarriers in the hair follicles of porcine ear skin. AB - Hair follicle research is currently focused on the development of drug-loaded nanocarriers for the targeting of follicular structures in the treatment of skin and hair follicle-related disorders. In the present study, a dual-label nanocarrier system was implemented in which FITC-labeled BSA hydrogel nanocarriers loaded with the model drug and dye TRITC-dextran were applied topically to porcine ear skin. Follicular penetration and the distribution of both dyes corresponding to the nanocarriers and the model drug in the follicular ducts subsequent to administration to the skin were investigated using confocal laser scanning microscopy. The release of TRITC-dextran from the particles was induced by washing of the nanocarriers, which were kept in a buffer containing TRITC-labeled dextran to balance out the diffusion of the dextran during storage, thereby changing the concentration gradient. The results showed a slightly but statistically significantly deeper follicular penetration of fluorescent signals corresponding to TRITC-dextran as opposed to fluorescence corresponding to the FITC-labeled particles. The different localizations of the dyes in the cross sections of the skin samples evidenced the release of the model drug from the labeled nanoparticles. PMID- 27693857 TI - Neuroprotective mechanism of Coenzyme Q10 (CoQ10) against PTZ induced kindling and associated cognitive dysfunction: Possible role of microglia inhibition. AB - BACKGROUND: Neuroinflammation, oxidative stress and mitochondrial dysfunction play a significant role to explain the pathophysiology of epilepsy. Neuroinflammation through microglia activation has been documented in epileptogenesis. Compounds which inhibit activation of glial cells have been suggested as one of the treatment approaches for the effective treatment of epilepsy. The present study has been designed to investigate the role of coenzyme Q10 and its interaction with minocycline (microglia inhibitor) against pentylenetetrazol (PTZ) induced kindling epilepsy. METHODS: Laca mice received Coenzyme Q10 and minocycline for a period of 29 days. PTZ (40mg/kg ip) injection has been given on alternate days. Various behavioural parameters (kindling score and elevated plus maze), biochemical parameters (lipid peroxidation, superoxide dismutase, reduced glutathione, catalase, nitrite and acetylcholinesterase) and mitochondrial enzyme complex activities of (I, II and IV) were assessed in the discrete areas of the brain. RESULTS: Administration of a subconvulsive dose of PTZ (40mg/kg) repeatedly increased significantly kindling score, oxidative damage and impaired mitochondrial enzyme complex activities (I, II and IV) and pro inflammatory marker (TNF-alpha) as compared to naive animals. Coenzyme Q10 (10, 20 and 40mg/kg) and minocycline (50 and 100mg/kg) for a duration of 29days significantly attenuated kindling score, reversed oxidative damage, TNF-alpha and restored mitochondrial enzyme complex activities (I, II and IV) as compared to control. Further, combinations of CoQ10 (10, 20mg/kg) with minocycline (50 and 100mg/kg) significantly modulate the protective effect of CoQ10 which was significant as compared to their effect per se in PTZ treated animals. CONCLUSION: The present study suggests the involvement of microglia inhibition in the protective effect of CoQ10 in PTZ induced kindling in mice. PMID- 27693858 TI - Egg structure and ultrastructure of Paterdecolyus yanbarensis (Insecta, Orthoptera, Anostostomatidae, Anabropsinae). AB - The egg structure of Paterdecolyus yanbarensis was examined using light, scanning electron and transmission electron microscopy. The egg surface shows a distinct honeycomb pattern formed by exochorionic ridges. Several micropyles are clustered on the ventral side of the egg. The egg membrane is composed of an exochorion penetrated with numerous aeropyles, an endochorion, and an extremely thin vitelline membrane. The endochorion is thickened at the posterior egg pole, probably associated with water absorption. A comparison of egg structure among Orthoptera revealed that the micropylar distribution pattern is conserved in Ensifera and Caelifera and might be regarded as a groundplan feature for each group; in Ensifera, multiple micropyles are clustered on the ventral side of the egg, whereas in Caelifera, micropyles are arranged circularly around the posterior pole of the egg. PMID- 27693860 TI - New Concepts in Hypertension Management: A Population-Based Perspective. AB - Hypertension (HTN) is the most common chronic disease in the U.S., and the standard model of office-based care delivery has yielded suboptimal outcomes, with approximately 50% of affected patients not achieving blood pressure (BP) control. Poor population-level BP control has been primarily attributed to therapeutic inertia and low patient engagement. New models of care delivery utilizing patient-generated health data, comprehensive assessment of social health determinants, computerized algorithms generating tailored interventions, frequent communication and reporting, and non-physician providers organized as an integrated practice unit, have the potential to transform population-based HTN control. This review will highlight the importance of these elements and construct the rationale for a reengineered model of care delivery for populations with HTN. PMID- 27693859 TI - Blood cell respirometry is associated with skeletal and cardiac muscle bioenergetics: Implications for a minimally invasive biomarker of mitochondrial health. AB - Blood based bioenergetic profiling strategies are emerging as potential reporters of systemic mitochondrial function; however, the extent to which these measures reflect the bioenergetic capacity of other tissues is not known. The premise of this work is that highly metabolically active tissues, such as skeletal and cardiac muscle, are susceptible to differences in systemic bioenergetic capacity. Therefore, we tested whether the respiratory capacity of blood cells, monocytes and platelets, are related to contemporaneous respirometric assessments of skeletal and cardiac muscle mitochondria. 18 female vervet/African green monkeys (Chlorocebus aethiops sabaeus) of varying age and metabolic status were examined for this study. Monocyte and platelet maximal capacity correlated with maximal oxidative phosphorylation capacity of permeabilized skeletal muscle (R=0.75, 95% confidence interval [CI]: 0.38-0.97; R=0.51, 95%CI: 0.05-0.81; respectively), isolated skeletal muscle mitochondrial respiratory control ratio (RCR; R=0.70, 95%CI: 0.35-0.89; R=0.64, 95%CI: 0.23-0.98; respectively), and isolated cardiac muscle mitochondrial RCR (R=0.55, 95%CI: 0.22-0.86; R=0.58, 95%CI: 0.22-0.85; respectively). These results suggest that blood based bioenergetic profiling may be used to report on the bioenergetic capacity of muscle tissues. Blood cell respirometry represents an attractive alternative to tissue based assessments of mitochondrial function in human studies based on ease of access and the minimal participant burden required by these measures. PMID- 27693861 TI - Hypertension Treatment in Blacks: Discussion of the U.S. Clinical Practice Guidelines. AB - Blacks are especially susceptible to hypertension (HTN) and its associated organ damage leading to adverse cardiovascular, cerebrovascular and renal outcomes. Accordingly, HTN is particularly significant in contributing to the black-white racial differences in health outcomes in the US. As such, in order to address these health disparities, practical clinical practice guidelines (CPGs) on how to treat HTN, specifically in blacks, are needed. This review article is a timely addition to the literature because the most recent U.S. CPG more explicitly emphasizes race into the algorithmic management of HTN. However, recent clinical research cautions that use of race as a proxy to determine therapeutic response to pharmaceutical agents may be erroneous. This review will address the implications of the use of race in the hypertension CPGs. We will review the rationale behind the introduction of race into the U.S. CPG and the level of evidence that was available to justify this introduction. Finally, we will conclude with practical considerations in the treatment of HTN in blacks. PMID- 27693862 TI - How do the definitions of urban and rural matter for transportation safety? Re interpreting transportation fatalities as an outcome of regional development processes. AB - Urban and rural places are integrated through economic ties and population flows. Despite their integration, most studies of road safety dichotomize urban and rural places, and studies have consistently demonstrated that rural places are more dangerous for motorists than urban places. Our study investigates whether these findings are sensitive to the definition of urban and rural. We use three different definitions of urban-rural continua to quantify and compare motor vehicle occupant fatality rates per person-trip and person-mile for the state of Wisconsin. The three urban-rural continua are defined by: (1) popular impressions of urban, suburban, and rural places using a system from regional economics; (2) population density; and (3) the intensity of commute flows to core urbanized areas. In this analysis, the three definitions captured different people and places within each continuum level, highlighting rural heterogeneity. Despite this heterogeneity, the three definitions resulted in similar fatality rate gradients, suggesting a potentially latent "rural" characteristic. We then used field observations of urban-rural transects to refine the definitions. When accounting for the presence of higher-density towns and villages in rural places, we found that low-density urban places such as suburbs and exurbs have fatality rates more similar to those in rural places. These findings support the need to understand road safety within the context of regional development processes instead of urban-rural categories. PMID- 27693865 TI - Help-seeking behaviors and mental well-being of first year undergraduate university students. AB - University students demonstrate poor help-seeking behatabviors for their mental health, despite often reporting low levels of mental well-being. The aims of this study were to examine the help-seeking intentions and experiences of first year university students in terms of their mental well-betabing, and to extaplore these students' views on formal (e.g. psychiatrists) and informal (e.g. friends) help-seeking. Students from a universitytab in the Republic of Ireland (n=220) completed an online questionnaire which focused on mental well-being and help seeking behaviors. Almost a third of students had sought help from a mental health professional. Very few students reported availing of university/online supports. Informal sources of help were more popular than formal sources, and those who would avail and had availed of informal sources demonstrated higher well-being scores. Counselors were the source of professional help most widely used. General practitioners, chaplains, social workers, and family therapists were rated the most helpful. Those with low/average well-being scores were less likely to seek help than those with higher scores. Findings indicate the importance of enhancing public knowledge of mental health issues, and for further examination of students' knowledge of help-seeking resources in order to improve the help-seeking behaviors and mental well-being of this population group. PMID- 27693864 TI - Acanthamoeba and Dictyostelium Use Different Foraging Strategies. AB - Amoeba often use cell movement as a mechanism to find food, such as bacteria, in their environment. The chemotactic movement of the soil amoeba Dictyostelium to folate or other pterin compounds released by bacteria is a well-documented foraging mechanism. Acanthamoeba can also feed on bacteria but relatively little is known about the mechanism(s) by which this amoeba locates bacteria. Acanthamoeba movement in the presence of folate or bacteria was analyzed in above agar assays and compared to that observed for Dictyostelium. The overall mobility of Acanthamoeba was robust like that of Dictyostelium but Acanthamoeba did not display a chemotactic response to folate. In the presence of bacteria, Acanthamoeba only showed a marginal bias in directed movement whereas Dictyostelium displayed a strong chemotactic response. A comparison of genomes revealed that Acanthamoeba and Dictyostelium share some similarities in G protein signaling components but that specific G proteins used in Dictyostelium chemotactic responses were not present in current Acanthamoeba genome sequence data. The results of this study suggest that Acanthamoeba does not use chemotaxis as the primary mechanism to find bacterial food sources and that the chemotactic responses of Dictyostelium to bacteria may have co-evolved with chemotactic responses that facilitate multicellular development. PMID- 27693863 TI - Host response to Clostridium difficile infection: Diagnostics and detection. AB - Clostridium difficile infection (CDI) is a significant healthcare concern worldwide, and C. difficile is recognised as the most frequent aetiological agent of infectious healthcare-associated diarrhoea in hospitalised adult patients. The clinical manifestation of CDI varies from self-limited diarrhoea to life threatening colitis. Such a broad disease spectrum can be explained by the impact of host factors. Currently, a complex CDI aetiology is widely accepted, acknowledging the interaction between bacteria and the host. C. difficile strains producing clostridial toxins A and B are considered toxigenic and can cause disease; those not producing the toxins are non-pathogenic. A person colonised with a toxigenic strain will not necessarily develop CDI. It is imperative to recognise patients with active disease from those only colonised with this pathogen and to implement appropriate treatment. This can be achieved by diagnostics that rely on host factors specific to CDI. This review will focus on major aspects of CDI pathogenesis and molecular mechanisms, describing host factors in disease progression and assessment of the host response in order to facilitate the development of CDI-specific diagnostics. PMID- 27693866 TI - Demographic and clinical characteristics of current comorbid psychiatric disorders in a randomized clinical trial for adults with stimulant use disorders. AB - This study aimed to determine if current comorbid psychiatric disorders differ in adults with cocaine use disorder, other stimulant (primarily methamphetamine) use disorder, or both, and identify demographic and clinical characteristics in those with increasing numbers of comorbid disorders. Baseline data from a randomized controlled trial beginning in residential settings (N=302) was used. Mood disorders were present in 33.6%, and anxiety disorders in 29.6%, with no differences among stimulant use disorder groups. Panic disorder was more frequently present with other stimulant use disorder. Those with two or more comorbid psychiatric disorders were more often female, White, had more symptoms of depression, greater propensity and risk for suicidal behavior, lower functioning in psychiatric and family domains, lower quality of life, more symptoms with stimulant abstinence and greater likelihood of marijuana dependence. Those with one or more comorbid disorders had more medical disorder burden, lower cognitive and physical functioning, greater pain, and higher rates of other drug dependence. With current comorbid psychiatric disorders, the morbidity of stimulant use disorders increases. Use of validated assessments near treatment entry, and a treatment plan targeting not only substance use and comorbid psychiatric disorders, but functional impairments, medical disorder burden and pain, may be useful. PMID- 27693867 TI - Patterns of antipsychotics' prescription in Portuguese acute psychiatric wards: A cross-sectional study. AB - This study aimed to establish the prescribing patterns of antipsychotics in acute psychiatric wards across Portugal, to determine the prevalence of polypharmacy and "high-doses" treatment, and to identify possible predictors. Twelve acute psychiatric inpatient units and 272 patients were included. The majority (87.5%) was treated with antipsychotics regardless of diagnosis, and 41.6% had at least two antipsychotics prescribed in combination. Age, use of depot antipsychotics, and antipsychotic "high-doses" were significant predictors of antipsychotic polypharmacy. Excluding 'as required' prescriptions, 13.8% of the patients were prescribed "high-doses" of antipsychotics. When antipsychotics 'as required' prescriptions were considered, 49.2% of the patients were on antipsychotic "high doses". Age, use of depot antipsychotics, previous psychiatric hospitalization and involuntary admission were significant predictors of antipsychotic "high doses". These results show that in Portugal the antipsychotics prescribing practices in psychiatric inpatient units diverge from those that are universally recommended, entailing important clinical and economic implications. It seems advisable to optimize the prescription of these drugs, in order to prevent adverse effects and improve the quality of the services provided. PMID- 27693868 TI - Ilizarov bone transport after massive tibial trauma: Case report. AB - INTRODUCTION: This is a case report of extreme lengthening of the tibia of about 14.5cm using bone transport technique following road traffic accident trauma to the lower limbs. The management of the subsequent massive skeletal defects was challenging to orthopedic surgeons. Based on reported cases, the highest tibial lengthening was 22cm using bifocal transport, while the highest unifocal tibial lengthening reached 14.5cm. CASE PRESENTATION: A 20-year-old male driver was brought to the emergency department after a road traffic accident. The patient had a right Gustilo IIIA segmental open tibia fracture with bone loss and other severe injuries. The tibial defect was 14.5cm and the patient was then admitted for Ilizarov application six months after the accident. Although this case was particularly complicated, full limb length was restored. DISCUSSION: The management of this case was directed to correct the deformities and achieve equal length of both limbs to restore the normal function. Several new techniques have been developed recently to fill large bone defects. Limb lengthening using bone transport technique by application of Ilizarov ring fixator has been suggested as the leading option in filling massive bone gaps. CONCLUSION: The use of bone transport technique using Ilizarov external rings has proved to be a minimally invasive and reliable method in managing massive bone defects. Accurate application of the Ilizarov frame and proper transport of the middle segment are important factors alleviating the risk for deviation of the transported segment. However, due to the need for regular follow-ups and monitoring, it demands high compliance from the patient to achieve optimal results. PMID- 27693869 TI - Colo-colonic intussusception due to large submucous lipoma: A case report. AB - INTRODUCTION: Intussusception in adult is rarely caused by idiopathic conditions. Main causes are inflammatory diseases, benign or malignant tumors and motility disorders. As a benign cause, lipomas appear as a particularly rare gastrointestinal intraluminal tumor occurring with highest incidence in the colon, mostly in the caecum and ascending colon. PRESENTATION OF CASE: A 57-year old male patient was admitted at the surgical emergency in Belo Horizonte, with history of chronic and intermittent diffuse abdominal pain, associated with variations of his bowel habits and rare episodes of vomiting starting around 3days prior to admission. DISCUSSION: Intussusception is the cause of adult symptomatic bowel obstruction in 1% of the cases and its colocolonic occurrence represents 17% of all intestinal intussusceptions in adults. The reported case presents itself as even rarer considering its evaluation according to the epidemiological statistics of 1:5 men/women ratio and lipoma's most common location being the right colon. Intussusception and intestinal obstructions caused by intraluminal lipomas are not often described in the literature and its occurrence is directly related to its size, usually larger than 2cm diameter. The management of lipomatous intraluminal lesions of the colon is traditionally surgical, and it allows a selective resection, depending on the size of the tumor, length of intussusception, and the amount of inflammation. CONCLUSION: Patients with chronic abdominal symptoms and semi-obstruction caused by intussusception are rarely diagnosed before surgery unless there is a high index of suspicion. Colonoscopy contributes to diagnosis given that it provides direct visualization and biopsy.

AB - INTRODUCTION: Acute pneumococcal peritonitis represents an unusual entity characterized by infection in the abdominal cavity despite the absence of an obvious causative source. Patients with portal hypertension such as cirrhotics and those with nefrotic syndrome are more frequently encountered in the every day practice. PRESENTATION OF CASE: A 14 years old female was referred to our department by his general practitioner with a 24h history of right lower abdominal pain and fever. Clinical examination was suggestive for peritonitis and the girl was transferred to the operation room. A diagnosis of primary pneumococcal peritonitis was made on the basis of the findings during surgery and the microbiological tests. Institution of appropriate antibiotics resulted to complete recovery. DISCUSSION: A mini literature review was performed. CONCLUSION: Primary bacterial peritonitis in adolescents is extremely rare. Surgeons are required to be aware of this entity. PMID- 27693871 TI - Supratherapeutic anti-factor Xa levels in patients receiving prophylactic doses of enoxaparin: A case series. AB - INTRODUCTION: Enoxaparin prophylaxis prevents venous thromboembolism in surgical patients. Real time anti-Factor Xa monitoring for surgical patients on enoxaparin prophylaxis is increasingly common. PRESENTATION OF CASES: We report on three cancer patients with therapeutic or supratherapeutic anti-Factor Xa levels while on prophylactic doses of enoxaparin after surgical procedures. In all cases, elevated anti-Factor Xa levels were the result of blood specimens being removed from a heparinized chemoport. DISCUSSION: This case series highlights the importance of peripheral venipuncture or appropriate blood wasting from central access sites for anti-Factor Xa levels. CONCLUSION: Inappropriately drawn anti Factor Xa levels may contribute to prophylaxis interruption or unnecessary workup for renal or liver failure.

AB - Photocatalytic fuel cell (PFC) is a potential wastewater treatment technology that can generate electricity from the conversion of chemical energy of organic pollutants. An immobilized ZnO/Zn fabricated by sonication and heat attachment method was applied as the photoanode and Pt/C plate was used as the cathode of the PFC in this study. Factors that affect the decolorization efficiency and electricity generation of the PFC such as different initial dye concentrations and pH were investigated. Results revealed that the degradation of Reactive Green 19 (RG19) was enhanced in a closed circuit PFC compared with that of a opened circuit PFC. Almost 100% decolorization could be achieved in 8 h when 250 mL of 30 mg L-1 of RG19 was treated in a PFC without any supporting electrolyte. The highest short circuit current of 0.0427 mA cm-2 and maximum power density of 0.0102 mW cm-2 was obtained by PFC using 30 mg L-1 of RG19. The correlation between dye degradation, conductivity and voltage output were also investigated and discussed.

AB - The formation of haloacetamides (HAcAms) and haloacetonitriles (HANs) from a solution containing natural organic matter and a secondary effluent sample was evaluated for disinfection by chlorination, chloramination, and chlorination followed by chloramination (Cl2NH2Cl process). The use of preformed monochloramine (NH2Cl) produced higher concentrations of HAcAms and lower concentrations of HANs than chlorination, while the Cl2NH2Cl process produced the highest concentrations of HAcAms and HANs. These results indicate that the Cl2NH2Cl process, which inhibited the formation of regulated trihalomethanes compared with chlorination, enhanced the formation of HAcAms and HANs. For disinfection in the presence of bromide, brominated dihaloacetamides and dihaloacetonitriles were formed, and the trends were similar to those observed for chlorinated species in the absence of bromide. The degrees of bromine substitution of dihaloacetamides and dihaloacetonitriles were highest for chlorination, followed by the Cl2NH2Cl process and then by the NH2Cl process. For the Cl2NH2Cl process, HAN formation kept gradually increasing with prechlorination time increasing from 0 to 120 min, while HAcAm formation increased only until it reached a maximum at around 10-30 min. These results suggest that the prechlorination time could be reduced to control the formation of HAcAms and HANs. During chloramination, the formation of HAcAms and HANs was lower when using preformed NH2Cl than when chloramines were formed in situ, with higher formation of HAcAms and HANs when chlorine was added before ammonia than vice versa for the secondary effluent; this finding suggests that preformed NH2Cl could be used to inhibit the formation of HAcAms and HANs during chloramination. PMID- 27693874 TI - A study of trace element contamination using multivariate statistical techniques and health risk assessment in groundwater of Chhaprola Industrial Area, Gautam Buddha Nagar, Uttar Pradesh, India. AB - This study is an investigation on spatio-chemical, contamination sources (using multivariate statistics), and health risk assessment arising from the consumption of groundwater contaminated with trace and toxic elements in the Chhaprola Industrial Area, Gautam Buddha Nagar, Uttar Pradesh, India. In this study 33 tubewell water samples were analyzed for 28 elements using ICP-OES. Concentration of some trace and toxic elements such as Al, As, B, Cd, Cr, Mn, Pb and U exceeded their corresponding WHO (2011) guidelines and BIS (2012) standards while the other analyzed elements remain below than those values. Background gamma and beta radiation levels were observed and found to be within their acceptable limits. Multivariate statistics PCA (explains 82.07 cumulative percent for total 6 of factors) and CA indicated (mixed origin) that natural and anthropogenic activities like industrial effluent and agricultural runoff are responsible for the degrading of groundwater quality in the research area. In this study area, an adult consumes 3.0 L (median value) of water therefore consuming 39, 1.94, 1461, 0.14, 11.1, 292.6, 13.6, 23.5 MUg of Al, As, B, Cd, Cr, Mn, Pb and U from drinking water per day respectively. The hazard quotient (HQ) value exceeded the safe limit of 1 which for As, B, Al, Cr, Mn, Cd, Pb and U at few locations while hazard index (HI) > 5 was observed in about 30% of the samples which indicated potential health risk from these tubewells for the local population if the groundwater is consumed. PMID- 27693875 TI - Prussian blue analogue derived magnetic carbon/cobalt/iron nanocomposite as an efficient and recyclable catalyst for activation of peroxymonosulfate. AB - A Prussian blue analogue, cobalt hexacyanoferrate Co3[Fe(CN)6]2, was used for the first time to prepare a magnetic carbon/cobalt/iron (MCCI) nanocomposite via one step carbonization of Co3[Fe(CN)6]2. The resulting MCCI consisted of evenly distributed cobalt and cobalt ferrite in a porous carbonaceous matrix, making it an attractive magnetic heterogeneous catalyst for activating peroxymonosulfate (PMS). As Rhodamine B (RhB) degradation was adopted as a model test for evaluating activation capability of MCCI, factors influencing RhB degradation were thoroughly examined, including MCCI and PMS dosages, temperature, pH, salt and radical scavengers. A higher MCCI dosage noticeably facilitated the degradation kinetics, whereas insufficient PMS dosage led to ineffective degradation. RhB degradation by MCCI-activated PMS was much more favorable at high temperatures and under neutral conditions. The presence of high concentration of salt slightly interfered with RhB degradation by MCCI-activated PMS. Through examining effects of radical scavengers, RhB degradation by MCCI activated PMS can be primarily attributed to sulfate radicals instead of a combination of sulfate and hydroxyl radicals. Compared to Co3O4, a typical catalyst for PMS activation, MCCI also exhibited a higher catalytic activity for activating PMS. In addition, MCCI was proven as a durable and recyclable catalyst for activating PMS over multiple cycles without efficiency loss and significant changes of chemical characteristics. These features demonstrate that MCCI, simply prepared from a one-step carbonization of Co3[Fe(CN)6]2 is a promising heterogeneous catalyst for activating PMS to degrade organic pollutants.

The retrocaval and retroiliac ureter, however, commonly present with symptoms due to ureteric obstruction. We present interesting computed tomography images of a 30 year-old male who was symptomatic for right upper ureteric obstruction and the ureter was coursing between the 2 common iliac veins that were uniting abnormally high at the level of right renal hilum with absence of infrarenal inferior vena cava. PMID- 27693876 TI - Button Cystostomy: Is it Really a Safe and Effective Therapeutic Option in Pediatric Patients With Neurogenic Bladder? AB - OBJECTIVE: To define safety and effectiveness of cystostomy button in the management of bladder drainage in pediatric patients with neurogenic bladder, and report our personalized surgical technique. MATERIALS AND METHODS: This study is a retrospective analysis of patients undergoing cystostomy button placement for bladder drainage from October 2009 to December 2015. Endoscopic and open surgical techniques and medium-term complication were analyzed and indications were recorded. RESULTS: Thirty-five patients, 16 (45.7%) females and 19 (54.3%) males, underwent cystostomy button placement for bladder drainage with a mean age of 8.6 +/- 4.8 years (standard deviation) and a mean follow-up time of 37 months. There were 91.4% of patients who had a neurogenic bladder; a nonobstructive urinary retention was diagnosed in the remainder of cases. A medium-term complication was mostly represented by urinary tract infection observed in 10 of 35 patients that was the most representative cause of button removal (4 of 35). Other observed complications were button leakage (n = 2), decubitus (n = 1), and bladder stone (n = 1). No postoperative complication was observed and no differences were found in terms of complications in the two surgical approaches performed. CONCLUSION: Cystostomy button is a safe and effective treatment for bladder drainage in neurogenic pediatric patients and it is also well accepted by patients and caregivers. Cystostomy button, which may avoid mechanical concerns and most of the social discomfort, should be considered an alternative method to other bladder drainage modalities. PMID- 27693878 TI - Dietary Inflammatory Index and Risk of Bladder Cancer in a Large Italian Case control Study. AB - OBJECTIVE: To evaluate the association between diet in relation to its inflammatory property and bladder cancer (BC) risk. METHODS: In this study we explored the association between the dietary inflammatory index (DII) and BC risk in an Italian case-control study conducted between 2003 and 2014. Cases were 690 patients with incident and histologically confirmed BC from 4 areas in Italy. Controls were 665 cancer-free subjects admitted to the same network of hospitals as cases for a wide spectrum of acute, non-neoplastic conditions. The DII was computed based on dietary intake assessed using a reproducible and valid 80-item food frequency questionnaire. Odds ratios (OR) were estimated through logistic regression models adjusting for age, sex, total energy intake, and other recognized confounding factors. RESULTS: Subjects in the highest quartile of DII scores (ie, with a more pro-inflammatory diet) had a higher risk of BC compared to subjects in the lowest quartile (ie, with an anti-inflammatory diet) (ORQuartile4vs1 = 1.97; 95% [confidence interval], 1.28, 3.03; P trend = .003). Stratified analyses produced stronger associations between DII and BC risk among females (ORQuartile4vs1 = 5.73; 95% CI = 1.46, 22.44), older >=65 years (ORQuartile4vs1 = 2.45; 95% CI = 1.38, 4.34), subjects with higher education >=7 years (ORQuartile4vs1 = 2.22; 95% CI = 1.27, 3.88), and never smokers (ORQuartile4vs1 = 4.04; 95% CI = 1.51, 10.80). CONCLUSION: A pro-inflammatory diet as indicated by higher DII scores is associated with increased BC risk. PMID- 27693880 TI - Qualitative and quantitative analysis of PMN/T-cell interactions by InFlow and super-resolution microscopy. AB - Neutrophils or polymorphonuclear cells (PMN) eliminate bacteria via phagocytosis and/or NETosis. Apart from these conventional roles, PMN also have immune regulatory functions. They can transdifferentiate and upregulate MHCII as well as ligands for costimulatory receptors which enables them to behave as antigen presenting cells (APC). The initial step for activating T-cells is the formation of an immune synapse between T-cells and antigen-presenting cells. However, the immune synapse that develops at the PMN/T-cell contact zone is as yet hardly investigated due to the non-availability of methods for analysis of large number of PMN interactions. In order to overcome these obstacles, we introduce here a workflow to analyse the immune synapse of primary human PMN and T-cells using multispectral imaging flow cytometry (InFlow microscopy) and super-resolution microscopy. For that purpose, we used CD3 and CD66b as the lineage markers for T cells and PMN, respectively. Thereafter, we applied and critically discussed various "masks" for identification of T-cell PMN interactions. Using this approach, we found that a small fraction of transdifferentiated PMN (CD66b+CD86high) formed stable PMN/T-cell conjugates. Interestingly, while both CD3 and CD66b accumulation in the immune synapse was dependent on the maturation state of the PMN, only CD3 accumulation was greatly enhanced by the presence of superantigen. The actin cytoskeleton was weakly rearranged at the PMN side on the immune synapse upon contact with a T-cell in the presence of superantigen. A more detailed analysis using super-resolution microscopy (structured-illumination microscopy, SIM) confirmed this finding. Together, we present an InFlow microscopy based approach for the large scale analysis of PMN/T-cell interactions and - combined with SIM - a possibility for an in-depth analysis of protein translocation at the site of interactions. PMID- 27693879 TI - Serum from obstructive sleep apnea patients induces inflammatory responses in coronary artery endothelial cells. AB - BACKGROUND AND AIMS: Obstructive sleep apnea (OSA) is characterized by intermittent airway obstruction and systemic hypoxia during sleep, which can contribute to an increase in reactive oxygen species, vascular remodeling, vasoconstriction and ultimately cardiovascular disease. Continuous positive airway pressure (CPAP) is a clinical therapy that maintains airway patency and mitigates several symptoms of OSA. However, it is currently unknown whether CPAP therapy also reduces the overall inflammatory potential in the circulation; to address this in an unbiased manner, we applied a novel endothelial biosensor approach, the serum cumulative inflammatory potential (SCIP) assay. METHODS: We studied healthy controls (n = 7), OSA subjects receiving no treatment, (OSA controls) (n = 7) and OSA subjects receiving CPAP for 3 months (n = 8). Serum was obtained from OSA subjects before and after CPAP or no treatment. A battery of quantitative and functional assays was performed to assess the serum inflammatory potential, in terms of endothelial responses. For the SCIP assay, human coronary artery endothelial cells (hCAECs) were incubated with 5% serum in media from individual subjects for 4 h. qPCR was performed to assess endothelial inflammatory transcript (ICAM-1, VCAM-1, IL-8, P-selectin, CCL5, and CXCL12) responses to serum. Additionally, transendothelial resistance was measured in serum-incubated hCAECs following leukocyte challenge. RESULTS: hCAECs exhibited significant increases in VCAM-1, ICAM-1, IL-8 and P-selectin mRNA when incubated with serum from OSA patients compared to serum from healthy control subjects. Furthermore, compared to no treatment, serum from CPAP-treated individuals was less potent at inducing inflammatory gene expression in the SCIP assay. Similarly, in a leukocyte adhesion assay, naive cells treated with serum from patients who received CPAP exhibited improved endothelial barrier function than cells treated with OSA control serum. CONCLUSIONS: OSA results in greater serum inflammatory potential, thereby driving endothelial activation and dysfunction. PMID- 27693881 TI - Mechanistic study of base-pairing small regulatory RNAs in bacteria. AB - In all three kingdoms of life, RNA is not only involved in the expression of genetic information, but also carries out extremely diverse cellular functions. This versatility is essentially due to the fact that RNA molecules can exploit the power of base pairing to allow them to fold into a wide variety of structures through which they can perform diverse roles, but also to selectively target and bind to other nucleic acids. This is true in particular for bacterial small regulatory RNAs that act by imperfect base-pairing with target mRNAs, and thereby control their expression through different mechanisms. Here we outline an overview of in vivo and in vitro approaches that are currently used to gain mechanistic insights into how these sRNAs control gene expression in bacteria. PMID- 27693882 TI - Aromatase deficiency in a male patient - Case report and review of the literature. AB - OBJECTIVE: Aromatase, or CYP19A1, is a type II cytochrome CYP450 enzyme that catalyzes the conversion of C19 androgens to C18 estrogens. Its crucial role in both female and male physiology has been deduced from human and animal studies using aromatase inhibitors, genetically altered mice, and patients with aromatase deficiency. The latter is an extremely rare disorder. Its diagnosis is particularly difficult in males, who go through puberty normally and therefore usually present as adults with elevated testosterone, bone abnormalities (e.g., delayed bone age and low bone mass), and metabolic syndrome. In this report, we describe a new case of a male patient with aromatase deficiency harboring a known mutation who presented with less severe clinical and biochemical features. CASE REPORT: The patient presented with low bone mass and delayed bone age after a finger fracture at age 25years. FSH, LH and testosterone levels were normal, but estradiol and estrone levels were absent or barely detectable, raising suspicion for aromatase deficiency. A homozygous c.628G>A mutation in exon 5 was confirmed by direct sequencing. Unlike previously reported cases of aromatase deficiency, he did not display biochemical features of insulin resistance, dyslipidemia, or overweight/obese status. Therapy with estradiol led to the closure of growth plates and a dramatic increase in bone mass. CONCLUSIONS: Here we explore genotype/phenotype associations of this new case compared to cases reported previously. We conclude that the specific nature of mutation c.628G>A, which can potentially result in several different forms of the aromatase enzyme, may lend an explanation to the variable phenotypes associated with this particular genotype. PMID- 27693883 TI - Equity issues were not fully addressed in Cochrane human immunodeficiency virus systematic reviews. AB - OBJECTIVE: To describe and summarize equity reporting in human immunodeficiency virus (HIV) systematic reviews and explore the extent to which equity issues are addressed and reported in HIV reviews using the PROGRESS Plus framework. STUDY DESIGN AND SETTING: Application of the PROGRESS Plus framework to a bibliometric analysis of HIV reviews in the Cochrane Database of Systematic Reviews. RESULTS: The analysis included 103 reviews published as of March 2014, with a median of five studies per review (first quartile; Q1 = 2; third quartile; Q3 = 11). Reporting of PROGRESS Plus factors was as follows: Place of residence (low, middle, and high income; 55.3%), place of residence (urban or rural; 24.3%), race or ethnicity (20.4%), occupation (10.7%), gender (65.0%), religion (1.9%), education (7.8%), socioeconomic position (10.7%), social networks and capital (1.0%), age (1.9%), and sexual orientation (3.8%). CONCLUSION: Gaps in the reporting of relevant equity indicators were identified within Cochrane HIV systematic review indicating that research is not consistently conducted through an equity lens. There is a need to incorporate PROGRESS Plus factors into both primary and secondary studies. PMID- 27693884 TI - Time-frequency analysis of intracranial EEG in patients with myoclonic seizures. AB - Myoclonic seizures are defined as generalized seizures according to the classification of seizure by the International League Against Epilepsy (ILAE). The pathogenesis of myoclonic seizures is not yet clear. There are very few studies on the focal surgical treatment of myoclonic seizures. The aim of this study is to investigate the characteristics of myoclonic seizure onset in different bands of the intracranial electroencephalogram (EEG) and their dynamic changes in temporal and spatial evolution. We studied four patients with myoclonic seizures who were under the focal resection of the epileptogenic zone. We retrospectively analyzed the semiology, electrocorticogram (ECoG) and imaging data of these patients, and conducted time-frequency analysis of broadband ECoG activity. We found that myoclonic seizures without clinical lateralizing signs could be improved by the resection of the epileptogenic zone. The ECoG power in different frequency bands increased to a peak at 0.5s before the clinical seizure onset and decreased quickly afterwards. The power of alpha activity was highest during the preictal and ictal periods. The central zone had higher power than the epileptogenic zone in all frequency bands during the preictal period, but this difference was not statistically significant. Our results suggest that myoclonic seizures in some patients might have a focal origination, with a fast bilateral propagating network in all frequency bands, especially the alpha band. PMID- 27693885 TI - Distinct electroencephalographic responses to disturbances and distractors during continuous reaching movements. AB - Discrepancies between actual and appropriate motor commands, dubbed low-level errors, have been shown to elicit a P300 like component. P300 has been studied extensively in cognitive tasks using, in particular, the three-stimulus oddball paradigm. This paradigm revealed two sub-components, known as P3a and P3b, whose relative contributions depend on saliency and task-relevance, respectively. However, the existence and roles of these sub-components in response to low-level errors are poorly understood. Here we investigated responses to low level errors generated by disturbances - including target and cursor jumps, versus responses to distractors, i.e., environmental changes that are irrelevant to the reaching task. Additionally, we examined the response to matching cursor and target jumps (dual jumps), which generate estimation errors, and are thus considered task relevant disturbances, but do not generate low level errors. We found that a significant P3a-like component is evoked by both disturbances and distractors, whereas the P3b-like component is significantly stronger in response to disturbances than distractors. The P3b-like component appears also in response to dual jumps, even though there are no low level errors. We conclude that disturbances and distractors elicit distinct responses, and that the P3b-like component reflects estimation errors rather than low-level errors. PMID- 27693886 TI - Bipolar I disorder with comorbid PTSD: Demographic and clinical correlates in a sample of hospitalized patients. AB - BACKGROUND: According to data from epidemiological and clinical samples, there are elevated rates of posttraumatic stress disorder (PTSD) among patients with bipolar disorder (BD). However, little is known about the clinical correlates that may distinguish patients with BD and comorbid PTSD from those without comorbid PTSD. The present study sought to elucidate those differences and examine factors, such as psychosis, history of suicide attempts, and comorbid personality disorders, which may predict comorbid PTSD in patients with BD-I. METHODS: We conducted a retrospective chart review of 230 psychiatric inpatients with BD-I. RESULTS: Patients with BD-I and comorbid PTSD were significantly more likely to be female, to be depressed (vs. manic), to have a comorbid personality disorder, and to have a history of suicide attempt. Also, BD-I patients with PTSD were significantly less likely to present for their inpatient hospital stay with psychosis. These effects remained significant after controlling for mood episode polarity, suggesting that findings were not fully explained by the higher incidence of depression in the comorbid PTSD group. CONCLUSIONS: Patients with BD I and comorbid PTSD appear to be a high risk population with need for enhanced monitoring of suicidality. Clinical implications of these findings are discussed. PMID- 27693887 TI - Intimate partner violence is associated with increased maternal hair cortisol in mother-child dyads. AB - BACKGROUND: The chronic consequences of intimate partner violence (IPV) on HPA activation are a topic of debate. The current study investigated hair cortisol concentrations in female victims of IPV and their children. METHODS: A total of 52 mother-child dyads were divided into two groups depending on exposure to IPV: IPV group (n=27 dyads) and control group (n=25 dyads). Hair cortisol concentration was measured in 1-cm-long hair strands, representing 30days of exposure before assessment. PTSD and depression symptoms were assessed in the mother and child. RESULTS: Women reporting IPV presented with higher hair cortisol levels, depression and PTSD symptoms severity in comparison to control women. Children who witnessed IPV reported more severe PTSD symptoms, but depressive symptoms and hair cortisol were not statistically different than those in control children. Correlation analyses revealed a positive association between the number of injury events and the level of hair cortisol in children. No associations between the hair cortisol levels in mothers and those in their children were found. CONCLUSION: Higher hair cortisol levels detected in women exposed to IPV reflected long-lasting changes in HPA axis functioning associated with chronic stress exposure. Children whose parents recurrently engage in violent conflicts with intimate partners may often feel threatened and consequently reporting more PTSD-related symptoms. Given that experiencing and witnessing violence during childhood and adolescence are predictive of intimate partner violence in adulthood, the need of early interventions is crucial. PMID- 27693889 TI - The risk of myocardial infarction with aromatase inhibitors relative to tamoxifen in post-menopausal women with early stage breast cancer. AB - BACKGROUND: Aromatase inhibitors (AIs) may increase cardiovascular risk relative to tamoxifen in post-menopausal women with breast cancer. This risk has not been well-quantified outside of clinical trials. METHODS: Observational population based cohort study of women aged >55 years diagnosed with stage I-III breast cancer between 2005 and 2010. Women treated with AIs or tamoxifen were followed to March 2012. The primary outcome was hospitalisation for myocardial infarction (MI). Cause-specific hazards were compared using tamoxifen as the reference group. Inverse probability of treatment weighting using the propensity score was used to reduce confounding due to measured baseline covariates. Results were confirmed using two cause-specific hazards models. Subgroup analyses included women aged >=66 years, those with prior ischaemic heart disease, and a 'lower risk group' aged <74 years with stage I-II cancer and no prior ischaemic heart disease. RESULTS: In 7409 aromatase inhibitor-treated and 1941 tamoxifen-treated women, the median age was 71 versus 74 years, respectively (p < 0.001). Baseline prevalence of ischaemic heart disease was similar (17.0% versus 16.9%, p = 0.96). Over a mean of 1184 d of follow-up, there were 123 hospitalisations for MI; the cause-specific hazard was higher with AIs (hazard ratio 2.02; 95% confidence interval 1.16-3.53 in the weighted sample). We observed comparable patterns within pre-defined subgroups and when adjusted using cause-specific hazards models. CONCLUSION: Aromatase inhibitors are associated with a higher risk of MI compared with tamoxifen. This risk should be accounted for when managing aromatase inhibitor-treated women. PMID- 27693890 TI - Photorespiration and the potential to improve photosynthesis. AB - The photorespiratory pathway, in short photorespiration, is an essential metabolite repair pathway that allows the photosynthetic CO2 fixation of plants to occur in the presence of oxygen. It is necessary because oxygen is a competing substrate of the CO2-fixing enzyme ribulose 1,5-bisphosphate carboxylase, forming 2-phosphoglycolate that negatively interferes with photosynthesis. Photorespiration very efficiently recycles 2-phosphoglycolate into 3 phosphoglycerate, which re-enters the Calvin-Benson cycle to drive sustainable photosynthesis. Photorespiration however requires extra energy and re-oxidises one quarter of the 2-phosphoglycolate carbon to CO2, lowering potential maximum rates of photosynthesis in most plants including food and energy crops. This review discusses natural and artificial strategies to reduce the undesired impact of air oxygen on photosynthesis and in turn plant growth. PMID- 27693888 TI - A phase I pharmacokinetic and pharmacodynamic study of the oral mitogen-activated protein kinase kinase (MEK) inhibitor, WX-554, in patients with advanced solid tumours. AB - PURPOSE: We performed a multi-centre phase I study to assess the safety, pharmacokinetics (PK) and pharmacodynamics (PD) of the orally available small molecule mitogen-activated protein kinase kinase (MEK) 1/2 inhibitor, WX-554, and to determine the optimal biological dose for subsequent trials. EXPERIMENTAL DESIGN: Patients with treatment-refractory, advanced solid tumours, with adequate performance status and organ function were recruited to a dose-escalation study in a standard 3 + 3 design. The starting dose was 25 mg orally once weekly with toxicity, PK and PD guided dose-escalation with potential to explore alternative schedules. RESULTS: Forty-one patients with advanced solid tumours refractory to standard therapies and with adequate organ function were recruited in eight cohorts up to doses of 150 mg once weekly and 75 mg twice weekly. No dose limiting toxicities were observed during the study, and a maximum tolerated dose (MTD) was not established. The highest dose cohorts demonstrated sustained inhibition of extracellular signal-regulated kinase (ERK) phosphorylation in peripheral blood mononuclear cells following ex-vivo phorbol 12-myristate 13 acetate stimulation. There was a decrease of 70 +/- 26% in mean phosphorylated (p)ERK in C1 day 8 tumour biopsies when compared with pre-treatment tumour levels in the 75 mg twice a week cohort. Prolonged stable disease (>6 months) was seen in two patients, one with cervical cancer and one with ampullary carcinoma. CONCLUSIONS: WX-554 was well tolerated, and an optimal biological dose was established for further investigation in either a once or twice weekly regimens. The recommended phase 2 dose is 75 mg twice weekly. PMID- 27693892 TI - Quality rating and private-prices: Evidence from the nursing home industry. AB - We use the rollout of the five-star rating of nursing homes to study how private pay prices respond to quality rating. We find that star rating increases the price differential between top- and bottom-ranked facilities. On average, prices of top-ranked facilities increased by 4.8 to 6.0 percent more than the prices of bottom-ranked facilities. We find stronger price effects in markets that are less concentrated where consumers may have more choices of alternative nursing homes. Our results suggest that with simplified design and when markets are less concentrated, consumers are more responsive to quality reporting. PMID- 27693891 TI - Convergent biosynthetic pathways to beta-lactam antibiotics. AB - Five naturally-occurring families of beta-lactams have inspired a class of drugs that constitute >60% of the antimicrobials used in human medicine. Their biosynthetic pathways reveal highly individualized synthetic strategies that yet converge on a common azetidinone ring assembled in structural contexts that confer selective binding and inhibition of d,d-transpeptidases that play essential roles in bacterial cell wall (peptidoglycan) biosynthesis. These enzymes belong to a single 'clan' of evolutionarily distinct serine hydrolases whose active site geometry and mechanism of action is specifically matched by these antibiotics for inactivation that is kinetically competitive with their native function. Unusual enzyme-mediated reactions and catalytic multitasking in these pathways are discussed with particular attention to the diverse ways the beta-lactam itself is generated, and more broadly how the intrinsic reactivity of this core structural element is modulated in natural systems through the introduction of ring strain and electronic effects. PMID- 27693893 TI - How product standardization affects choice: Evidence from the Massachusetts Health Insurance Exchange. AB - This paper examines the effect of choice architecture on Massachusetts' Health Insurance Exchange. A policy change standardized cost-sharing parameters of plans across insurers and altered information presentation. Post-change, consumers chose more generous plans and different brands, but were not more price sensitive. We use a discrete choice model that allows the policy to affect how attributes are valued to decompose the policy's effects into a valuation effect and a product availability effect. The brand shifts are largely explained by the availability effect and the generosity shift by the valuation effect. A hypothetical choice experiment replicates our results and explores alternative counterfactuals. PMID- 27693894 TI - Antibacterial mechanism of daptomycin antibiotic against Staphylococcus aureus based on a quantitative bacterial proteome analysis. AB - : Daptomycin (DAP) is a novel lipopeptide antibiotic which exhibits excellent antibacterial activity against most clinically relevant Gram-positive bacteria, but the DAP-targeting protein molecules against host bacterial infection are far from clear. In order to discover bacterial protein response to DAP treatment, an iTRAQ-based quantitative proteomic analysis was applied to identify differential bacterial proteome profiling of Staphylococcus aureus (S. aureus) ATCC 25923 to 0.125MUg/ml DAP exposure. Totally 51 bacterial proteins were significantly changed with DAP treatment, among which 34 proteins were obviously up-regulated and 17 proteins were down-regulated. Meanwhile, 139 bacterial cell membrane (CM) proteins were identified, and 7 CM proteins were significantly altered to decrease CM potential to disrupt bacterial cell membrane. Especially the up regulation of NDK and down-regulation of NT5 in several S. aureus strains are validated to be a universal variation tendency response to DAP treatment. Under DAP exposure, bacterial membrane potential is decreased and cell membrane is disrupted, and bacterial chromosome is aggregated, which contributes to bacterial DNA rapid release and induces bacteria death within 2-5h. In general, multiple bacterial protein expressions are changed in response to DAP antibiotic exposure, which disrupts host bacterial physiology by multiple cellular levels. To our knowledge, this is the first time to exactly identify infectious bacterial proteins in response to DAP antibiotic action. Our findings help better understand DAP antibacterial mechanism and develop novel DAP derivatives against the upcoming antibiotic-resistant bacterial infection. BIOLOGICAL SIGNIFICANCE: DAP is a novel lipopeptide antibiotic that it exhibits excellent in vitro activity against most clinically relevant Gram-positive bacteria, and the investigations on its pharmaceutical action mode of DAP have dramatically increased in the past decade due to its unique antimicrobial mechanism. However, the target molecules of DAP acting on the infectious bacteria, are far from clear. The state-of-the-art quantitative proteomic technologies provide new avenues to uncover underlying mechanism of antibiotics. Our research main aims to identify bacterial proteome profiling of host strain S. aureus response to DAP treatment through an iTRAQ-based quantitative proteomic analysis, which contributes to understand DAP efficient antibacterial activity and the microbial antibiotic interactions.

AB - CONTEXT: Treatment of pain in cancer is a clinical priority. Many cancer patients seek and use complementary and alternative medicine (CAM) therapies. OBJECTIVES: The aim of this study was to describe the role CAM plays in oncology, clinicians' approaches to pain management and its alignment with patient preference and self care. METHODS: We used quantitative criteria to identify patients with high, self reported pain and reduced quality of life. For these patients, we merged quantitative and qualitative data from encounter audio recordings, patient surveys, and the medical record. RESULTS: We identified 32 patients (72% women, average age 60) experiencing significantly symptomatic pain at enrollment. Merged themes were 1) Restricted and defined roles: Oncology clinicians suggested and documented cancer-specific approaches to pain management. Patients often (17, 53%) used CAM but rarely desired to discuss it in their encounters. 2) Proactive patients in setting of neutrality: Pain management strategies were considered in 22 instances. CAM was mentioned in 4 (18%) of these discussions but only after patient initiation. Clinicians took a neutral stance. 3) Missed opportunities for person-centered CAM discussions and management: Most (88%) patients were receiving conventional pain medications at enrollment or had them added or escalated during follow-up. Some patients in pain expressed preferences for avoiding opioids. One patient reported wishing CAM would have been discussed after an encounter in which it was not. CONCLUSION: Bringing CAM discussions into the oncology encounter may facilitate a stronger patient-clinician partnership and a more open and safe understanding of pain-related CAM use. PMID- 27693896 TI - The Association Between Pain and Clinical Outcomes in Adolescents With Cystic Fibrosis. AB - CONTEXT: Pain is a common problem in patients with cystic fibrosis (CF) and in adults is associated with lower quality of life and more pulmonary complications. Less is known about the impact of pain in adolescents with CF. OBJECTIVES: This study aimed to describe pain in an adolescent CF population and to determine if pain at baseline is associated with lower health-related quality of life (HRQoL) and worse pulmonary outcomes at six-month follow-up. METHODS: We administered surveys at baseline and at six months to CF patients aged 12 to 20 years. Analyses included Wilcoxon log-rank tests, Spearman correlations, and linear and logistic regressions. RESULTS: Seventy-three patients (86.9%) completed the baseline questionnaire and 53 patients (63.1%) completed the six-month follow-up questionnaire. Mean age was 15.6 +/- 2.5 and mean FEV1 was 79 +/- 26% predicted; 89% of patients reported pain in the three months before the survey, but in most it was short lived and mild to moderate in severity. Abdominal pain was the most common location. Pain was associated with increased pulmonary exacerbations (odds ratios = 1.99 for every one-point increase on a composite pain scale, P = 0.03) and with lower HRQoL. CONCLUSIONS: Pain in adolescents with CF is associated with lower HRQoL and more pulmonary exacerbations. Greater efforts are needed to manage pain in this population and to determine if treatment of pain improves other outcomes. PMID- 27693897 TI - Authors' Reply to Davies et al. PMID- 27693898 TI - EffenDys-Fentanyl Buccal Tablet for the Relief of Episodic Breathlessness in Patients With Advanced Cancer: A Multicenter, Open-Label, Randomized, Morphine Controlled, Crossover, Phase II Trial. AB - CONTEXT: Episodic breathlessness is a frequent and burdensome symptom in cancer patients but pharmacological treatment is limited. OBJECTIVES: To determine time to onset, efficacy, feasibility, and safety of transmucosal fentanyl in comparison to immediate-release morphine for the relief of episodic breathlessness. METHODS: Phase II, investigator-initiated, multicenter, open label, randomized, morphine-controlled, crossover trial with open-label titration of fentanyl buccal tablet (FBT) in inpatients with incurable cancer. The primary outcome was time to onset of meaningful breathlessness relief. Secondary outcomes were efficacy (breathlessness intensity difference at 10 and 30 minutes; sum of breathlessness intensity difference at 15 and 60 minutes), feasibility, and safety. Study was approved by local ethics committees. RESULTS: Twenty-five of 1341 patients were eligible, 10 patients agreed to participate (four female, mean age 58 +/- 11, mean Karnofsky score 67 +/- 11). Two patients died before final visits and two patients dropped-out because of disease progression leaving six patients for analysis with 61 episodes of breathlessness. Mean time to onset was for FBT 12.7 +/- 10.0 and for immediate-release morphine 23.6 +/- 15.1 minutes with a mean difference of -10.9 minutes (95% CI = -24.5 to 2.7, P = 0.094). Efficacy measures were predominately in favor for FBT. Both interventions were safe. Feasibility failed because of too much study demands for a very ill patient group. CONCLUSION: The description of a faster and greater relief of episodic breathlessness by transmucosal fentanyl versus morphine justifies further evaluation by a full-powered trial. PMID- 27693899 TI - A Comparison of Circumstances at the End of Life in a Hospital Setting for Children With Palliative Care Involvement Versus Those Without. AB - CONTEXT: Specialized pediatric palliative care (PPC) services have become more common in urban pediatric hospital settings, although little is known about palliative care specialist involvement. OBJECTIVES: The objective of this study was to compare circumstances before death in children who spent their last days of life in an inpatient pediatric hospital setting, with or without PPC provider involvement during their inpatient stay. METHODS: Retrospective chart review of medical records of children for the last inpatient stay that resulted in death at a children's hospital setting between January 2012 through June 2013. The setting was a free-standing, 385-bed tertiary care children's hospital. RESULTS: Charts were reviewed for 114 children between 0 and 18 years of age, who were hospitalized for at least 24 hours before their death. Half of the children who died as inpatients were infants (median age five weeks). Children who received an inpatient PPC consult (25% of the sample) experienced 1) a higher rate of pain assessments, 2) better documentation around specific actions to manage pain, 3) greater odds of receiving integrative medicine services, 4) fewer diagnostic/monitoring procedures (e.g., blood gases, blood draws, placements of intravenous lines) in the last 48 hours of life, and 5) nearly eight times greater odds of having a do-not-resuscitate order in place at the time of death. CONCLUSION: The integration of a PPC team was associated with fewer diagnostic/monitoring procedures and improved pain management documentation in this study of 114 children who died as inpatients. PMID- 27693900 TI - Pain Assessment, Management, and Control Among Patients 65 Years or Older Receiving Hospice Care in the U.S. AB - CONTEXT: Knowledge is limited regarding pain assessment and management practices, as well as pain-related outcomes in hospice care. OBJECTIVES: To generate national estimates of pain assessment and management practices and outcomes of pain control among patients 65 years or older receiving hospice care in the U.S. and identify hospice discharge and agency characteristics predicting study outcomes. METHODS: The 2007 National Home Health and Hospice Care Survey was analyzed. Multivariate logistic regressions were estimated to identify discharge and agency characteristics predicting guideline-concordant pain assessment and management practices and pain control outcomes. RESULTS: A high percentage of discharges had pain assessment at admission (97%) and before discharge (93%); use of valid pain rating scales was relatively low (69% and 54% for first and last assessments, respectively). Almost 95% of patients received pain medication, but only 42% received nonpharmacologic therapies. About 70% of patients assessed with a valid pain scale saw improvement in the level of pain or remained free of pain from admission to discharge. Non-Hispanic blacks were less likely to have pain assessments, and Hispanics were less likely to receive opioid analgesics or to have pain-free status at discharge, compared with non-Hispanic whites. Patients receiving care from for-profit (vs. nonprofit) agencies were more likely to receive pain assessment with a valid scale before discharge but less likely to experience pain control or improvement. CONCLUSION: Greater use of valid pain assessment scales and nonpharmacologic therapies constitutes areas for improvement in hospice care. Targeted interventions are needed to address disparities in pain care by patient race and/or ethnicity and agency ownership status. PMID- 27693901 TI - Efficacy and Safety of Two Methadone Titration Methods for the Treatment of Cancer-Related Pain: The EQUIMETH2 Trial (Methadone for Cancer-Related Pain). AB - CONTEXT: In the European Association for Palliative Care recommendations for cancer pain management, there was no consensus regarding the indications, titration, or monitoring of methadone. OBJECTIVES: This national, randomized, multicenter trial aimed to compare two methadone titration methods (stop-and-go vs. progressive) in patients with cancer-related pain who were inadequately relieved by or intolerant to Level 3 opioids. METHODS: The primary end point was the rate of success/failure at Day 4, defined as pain relief (reduction of at least two points on the visual scale and a pain score <5 for two consecutive days) and no overdose (Rudkin scale >=3 and respiratory rate <8/minute). The patients were followed for two months after enrollment. RESULTS: The cancer related pain characteristics of the 146 patients were as follows: 16% were nociceptive, 85% experienced breakthrough pain, and 84% had mixed types of pain. The reasons for switching to methadone were a lack of efficacy that was either isolated (56%) or associated with intolerance (38%). Adequate pain relief was obtained in 80% of the patients (median of three days in both groups [P = 0.12]) and lasted until D56. The rate of success/failure was approximately 40% at Day 4 in both groups, with overdoses in 13% of the patients throughout the study. The two methods were considered equally easy to perform by nearly 60% of the clinicians. CONCLUSION: Methadone is an effective and sustainable second-line alternative opioid for the treatment of cancer-related pain. The methods of titration are comparable in terms of efficacy, safety, and ease of use. PMID- 27693902 TI - The Effect of Pediatric Palliative Care Policy on Hospice Utilization Among California Medicaid Beneficiaries. AB - CONTEXT: California implemented pediatric palliative care legislations that allowed children to receive curative and supportive care from diagnosis of a life threatening serious illness in 2010. Palliative care policies may improve access to hospice care as children near end of life. OBJECTIVES: The aim of this study was to examine the effect of the palliative care policy on hospice utilization for children and their families was investigated. METHODS: Using 2007 and 2010 California Medicaid data, a difference-in-difference analysis was conducted to analyze hospice use (i.e., hospice enrollment, hospice length of stay) changes for children who resided in pediatric policy counties relative to those who did not. The sample of children in California who died with a life-threatening serious illness in 2007 and 2010 equaled 979 children. RESULTS: More than 10% of children enrolled in hospice care with an average of less than 3 days of hospice care. The palliative care policy did not have any effect on hospice enrollment. However, the policy was positively associated with increasing days in hospice care (incidence rate ratio = 5.61, P < 0.05). The rate of hospice length of stay increased by a factor of 5.61 for children in palliative care counties compared with children unaffected by the policy. CONCLUSION: The pediatric palliative care policy was associated with longer lengths of stay in hospice once the children were enrolled. Policies promoting palliative care are critical to ensuring access to hospice care for children. PMID- 27693903 TI - Reliability and Validity of the Spanish Version of the Memorial Symptom Assessment Scale in Oncology Patients. AB - CONTEXT: Memorial Symptom Assessment Scale (MSAS) is a multidimensional tool developed to evaluate frequency, severity, and distress of common symptoms present in cancer patients. OBJECTIVE: To translate the original English version of MSAS and prove the reliability and validity of the Spanish version. METHODS: MSAS scale was translated into Spanish and administered to 246 cancer patients aged between 18 and 85 years. They attended the Day Hospital to receive chemotherapy. European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 and Rotterdam Symptom Checklist were used to test criterion validity. RESULTS: TOTAL MSAS, Physical Symptom Subscale (PHYS), Psychological Symptom Subscale (PSYCH), and Global Distress Index (GDI) reported high internal consistency: 0.891, 0.801, 0.825, 0.813, respectively. Exploratory factor analysis identified two-factors structure and confirmatory factor analysis showed good adjustment rates. The emotional functioning subscale of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 highly correlated with PSYCH (r = -0.868; P < 0.001) and GDI (r = -0.810; P < 0.001), whereas social functioning subscale correlated with PSYCH (r = 0.704; P < 0.001) and GDI (r = -0.624; P < 0.001). The PHYS of Rotterdam Symptom Checklist correlated with PHYS (r = 0.876; P < 0.001) and the PSYCH with PSYCH (r = 0.872; P < 0.001). CONCLUSION: The Spanish version of MSAS was determined to be a valid and reliable scale in cancer patients. PMID- 27693904 TI - Developing a Medical School Curriculum for Psychological, Moral, and Spiritual Wellness: Student and Faculty Perspectives. AB - CONTEXT: Although many studies have addressed the integration of a religion and/or spirituality curriculum into medical school training, few describe the process of curriculum development based on qualitative data from students and faculty. OBJECTIVES: The aim of this study is to explore the perspectives of medical students and chaplaincy trainees regarding the development of a curriculum to facilitate reflection on moral and spiritual dimensions of caring for the critically ill and to train students in self-care practices that promote professionalism. METHODS: Research staff conducted semiscripted and one-on-one interviews and focus groups. Respondents also completed a short and self-reported demographic questionnaire. Participants included 44 students and faculty members from Harvard Medical School and Harvard Divinity School, specifically senior medical students and divinity school students who have undergone chaplaincy training. RESULTS: Two major qualitative themes emerged: curriculum format and curriculum content. Inter-rater reliability was high (kappa = 0.75). With regard to curriculum format, most participants supported the curriculum being longitudinal, elective, and experiential. With regard to curriculum content, five subthemes emerged: personal religious and/or spiritual (R/S) growth, professional integration of R/S values, addressing patient needs, structural and/or institutional dynamics within the health care system, and controversial social issues. CONCLUSION: Qualitative findings of this study suggest that development of a future medical school curriculum on R/S and wellness should be elective, longitudinal, and experiential and should focus on the impact and integration of R/S values and self-care practices within self, care for patients, and the medical team. Future research is necessary to study the efficacy of these curricula once implemented. PMID- 27693906 TI - Beyond blindness: On the role of organism and environment in trial generation. AB - In this paper we aim to amend the traditional analogy at the heart of evolutionary epistemologies. We shall first argue, contrary to what has been frequently done, that both hypothesis generation and the processes of generation of genetic and phenotypic change are often directed as well as environmentally conditioned. Secondly, we shall argue that environmental influence does not affect trial generation directly but that environmental information is processed by the epistemic agent and by the biological organism respectively. Thirdly, we suggest conceiving hypothesis generation as a process of manipulative abduction and the generation of biological variation as a process mediated by phenotypic plasticity. Finally, we argue that manipulative abduction and environmentally induced biological variation modulated by plasticity are analogous because they both involve a conjectural response to environmental cues. Our analysis thus vindicates a revised version of evolutionary epistemology ascribing a fundamental role to both organism and environment in trial generation. This perspective, in our opinion, offers support to the thesis, inspired by the theory of embodied cognition, that hypothesis generation is sometimes explained by an appeal to phenotypic plasticity. PMID- 27693905 TI - Cognitive and emotional processing of pleasant and unpleasant experiences in major depression: A matter of vantage point? AB - BACKGROUND AND OBJECTIVES: In nonclinical populations, adopting a third-person perspective as opposed to a first-person perspective while analyzing negative emotional experiences fosters understanding of these experiences and reduces negative emotional reactivity. We assessed whether this generalizes to people with major depression (MD). Additionally, we assessed whether the emotion reducing effects of adopting a third-person perspective also occur when subjects with MD and HC subjects analyze positive experiences. METHODS: Seventy-two MD subjects and 82 HC subjects analyzed a happy and a negative experience from either a first-person or a third-person perspective. RESULTS: Unexpectedly, we found no emotion-reducing effects of third-person perspective in either group thinking about negative events. However, across groups, third-person perspective was associated with less recounting of negative experiences and with a clearer, more coherent understanding of them. Negative affect decreased and positive affect increased in both groups analyzing happy experiences. In MD subjects, decreases in depressive affect were stronger for the third-person perspective. In both groups, positive affect increased and negative affect decreased more strongly for the third-person perspective. LIMITATIONS: While reflecting on their positive memory, MD subjects adopted their assigned perspective for a shorter amount of time (70%) than HC subjects (78%). However, percentage of time participants adopted their assigned perspective was unrelated to the significant effects we found. CONCLUSIONS: Both people suffering from MD and healthy individuals may benefit from processing pleasant experiences, especially when adopting a self-distant perspective. PMID- 27693907 TI - An infrared diagnostic system to detect causal agents of grapevine trunk diseases. AB - In most vineyards worldwide, agents of grapevine trunk diseases represent a real threat for viticulture and are responsible for significant economic loss to the wine industry. The conventional microbiological isolation technique used to diagnose this disease is tedious and frequently leads to false negatives. Thus, a dire need exists for an alternative method to detect this disease. One possible way involves infrared spectroscopy, which is a rapid, nondestructive analytical tool that is commonly used for quality control of feed stuffs. In the present work, a midinfrared spectrometer was tested as a fast tool for detecting agents of grapevine trunk disease. Midinfrared spectra were collected from 70 Vitis vinifera L. cv. Cabernet-Sauvignon one year old trunk-wood samples that were infected naturally in one viticulture nursery of the south of France. The samples underwent polymerase chain reaction and morphological identification, and the results were correlated to the midinfrared spectra by using multivariate analysis to discriminate between noninfected and infected samples. Based on comparison with some control samples, the highest percentage of correct identification of fungal contamination when using the midinfrared spectroscopy method is 80%. PMID- 27693908 TI - Multicenter evaluation of molecular and culture-dependent diagnostics for Shigella species and Entero-invasive Escherichia coli in the Netherlands. AB - An inter-laboratory collaborative trial for the evaluation of diagnostics for detection and identification of Shigella species and Entero-invasive Escherichia coli (EIEC) was performed. Sixteen Medical Microbiological Laboratories (MMLs) participated. MMLs were interviewed about their diagnostic methods and a sample panel, consisting of DNA-extracts and spiked stool samples with different concentrations of Shigella flexneri, was provided to each MML. The results of the trial showed an enormous variety in culture-dependent and molecular diagnostic techniques currently used among MMLs. Despite the various molecular procedures, 15 out of 16 MMLs were able to detect Shigella species or EIEC in all the samples provided, showing that the diversity of methods has no effect on the qualitative detection of Shigella flexneri. In contrast to semi quantitative analysis, the minimum and maximum values per sample differed by approximately five threshold cycles (Ct-value) between the MMLs included in the study. This indicates that defining a uniform Ct-value cut-off for notification to health authorities is not advisable. PMID- 27693909 TI - Regulation of actin filament turnover by cofilin-1 and cytoplasmic tropomyosin isoforms. AB - Tropomyosin and cofilin are actin-binding proteins which control dynamics of actin assembly and disassembly. Tropomyosin isoforms can either inhibit or enhance cofilin activity, but the mechanism of this diverse regulation is not well understood. In this work mechanisms of actin dynamics regulation by four cytoskeletal tropomyosin isoforms and cofilin-1 were studied with the use of biochemical and fluorescent microscopy assays. The recombinant tropomyosin isoforms were products of two genes: TPM1 (Tpm1.6 and Tpm1.8) and TPM3 (Tpm3.2 and Tpm3.4). Tpm1.6/1.8 bound to F-actin with higher apparent binding constants and lower cooperativities than Tpm3.2/3.4. In consequence, subsaturating concentrations of cofilin-1 removed 50% of Tpm3.2/3.4 from F-actin. By contrast, 2 and 5.5 molar excess of cofilin-1 over actin was required to dissociate 50% of Tpm1.6/1.8. All tropomyosins inhibited the rate of spontaneous polymerization of actin, which was reversed by cofilin-1. Products of TPM1 favored longer filaments and protected them from cofilin-induced depolymerization. This was in contrast to the isoforms derived from TPM3, which facilitated depolymerization. Tpm3.4 was the only isoform, which increased frequency of the filament severing by cofilin 1. Tpm1.6/1.8 inhibited, but Tpm3.2/3.4 enhanced cofilin-induced conformational changes leading to accelerated release of rhodamine-phalloidin from the filament. We concluded that the effects were executed through different actin affinities of tropomyosin isoforms and cooperativities of tropomyosin and cofilin-1 binding. The results obtained in vitro were in good agreement with localization of tropomyosin isoforms in stable or highly dynamic filaments demonstrated before in various cells. PMID- 27693910 TI - Is the clinical relevance of drug-food and drug-herb interactions limited to grapefruit juice and Saint-John's Wort? AB - An interaction of drug with food, herbs, and dietary supplements is usually the consequence of a physical, chemical or physiologic relationship between a drug and a product consumed as food, nutritional supplement or over-the-counter medicinal plant. The current educational review aims at reminding to the prescribing physicians that the most clinically relevant drug-food interactions may not be strictly limited to those with grapefruit juice and with the Saint John's Wort herbal extract and may be responsible for changes in drug plasma concentrations, which in turn decrease efficacy or led to sometimes life threatening toxicity. Common situations handled in clinical practice such as aging, concomitant medications, transplant recipients, patients with cancer, malnutrition, HIV infection and those receiving enteral or parenteral feeding may be at increased risk of drug-food or drug-herb interactions. Medications with narrow therapeutic index or potential life-threatening toxicity, e.g., the non steroidal anti-inflammatory drugs, opioid analgesics, cardiovascular medications, warfarin, anticancer drugs and immunosuppressants may be at risk of significant drug-food interactions to occur. Despite the fact that considerable effort has been achieved to increase patient' and doctor's information and ability to anticipate their occurrence and consequences in clinical practice, a thorough and detailed health history and dietary recall are essential for identifying potential problems in order to optimize patient prescriptions and drug dosing on an individual basis as well as to increase the treatment risk/benefit ratio. PMID- 27693911 TI - Total synthesis and the anticancer activity of (+)-spisulosine. AB - The total synthesis of the anticancer agent (+)-spisulosine has been accomplished. The strategy involved a substrate-controlled aza-Claisen rearrangement to establish the erythro-configured amino-alcohol motif followed by deoxygenation to create a methyl side-chain. Subsequent Wittig olefination then permitted the construction of the carbon backbone of the target molecule. To investigate the antiproliferative effect of 1, its biological profile was examined on a panel of 6 human malignant cell lines and demonstrated the significant anticancer activity of 1 on at least five of the evaluated lines with IC50 < 1 MUM (MCF-7, HTC-116, Caco-2, Jurkat and HeLa). PMID- 27693912 TI - Diastereoselective synthesis of furanose and pyranose substituted glycine and alanine derivatives via proline-catalyzed asymmetric alpha-amination of aldehydes. AB - A concise organocatalytic route toward the synthesis of furanose and pyranose substituted glycine and alanine derivatives is reported. These compounds are core structural units of some of the naturally available antibiotics and antifungal agents. Proline-catalyzed asymmetric alpha-amination of aldehydes derived from sugars is used as the key reaction to synthesize twelve sugar amino acid derivatives. The asymmetric transformations proceeded in good yields and with good to excellent diastereoselectivity. The application of the synthesized amino acids is demonstrated by synthesizing a tripeptide containing one of them. PMID- 27693913 TI - Differential subcellular distribution of four phospholipase C isoforms and secretion of GPI-PLC activity. AB - Phospholipase C (PLC) is an important enzyme of signal transduction pathways by generation of second messengers from membrane lipids. PLCs are also indicated to cleave glycosylphosphatidylinositol (GPI)-anchors of surface proteins thus releasing these into the environment. However, it remains unknown whether this enzymatic activity on the surface is due to distinct PLC isoforms in higher eukaryotes. Ciliates have, in contrast to other unicellular eukaryotes, multiple PLC isoforms as mammals do. Thus, Paramecium represents a perfect model to study subcellular distribution and potential surface activity of PLC isoforms. We have identified distinct subcellular localizations of four PLC isoforms indicating functional specialization. The association with different calcium release channels (CRCs) argues for distinct subcellular functions. They may serve as PI PLCs in microdomains for local second messenger responses rather than free floating IP3. In addition, all isoforms can be found on the cell surface and they are found together with GPI-cleaved surface proteins in salt/ethanol washes of cells. We can moreover show them in medium supernatants of living cells where they have access to GPI-anchored surface proteins. Among the isoforms we cannot assign GPI-PLC activity to specific PLC isoforms; rather each PLC is potentially responsible for the release of GPI-anchored proteins from the surface. PMID- 27693914 TI - Specific interaction of IM30/Vipp1 with cyanobacterial and chloroplast membranes results in membrane remodeling and eventually in membrane fusion. AB - The photosynthetic light reaction takes place within the thylakoid membrane system in cyanobacteria and chloroplasts. Besides its global importance, the biogenesis, maintenance and dynamics of this membrane system are still a mystery. In the last two decades, strong evidence supported the idea that these processes involve IM30, the inner membrane-associated protein of 30kDa, a protein also known as the vesicle-inducing protein in plastids 1 (Vipp1). Even though we just only begin to understand the precise physiological function of this protein, it is clear that interaction of IM30 with membranes is crucial for biogenesis of thylakoid membranes. Here we summarize and discuss forces guiding IM30-membrane interactions, as the membrane properties as well as the oligomeric state of IM30 appear to affect proper interaction of IM30 with membrane surfaces. Interaction of IM30 with membranes results in an altered membrane structure and can finally trigger fusion of adjacent membranes, when Mg2+ is present. Based on recent results, we finally present a model summarizing individual steps involved in IM30 mediated membrane fusion.

PMID- 27693916 TI - Inducible costimulator (ICOS) potentiates TCR-induced calcium flux by augmenting PLCgamma1 activation and actin remodeling. AB - The inducible costimulator (ICOS) is a T cell costimulatory receptor that plays crucial roles in T cell differentiation and function. So far, ICOS has been shown to activate three signaling components: phosphoinositide 3-kinase (PI3K), intracellular calcium mobilization, and TANK binding kinase 1 (TBK1). By generating a knock-in strain of mice in which the ICOS gene is modified such that the ICOS-mediated PI3K pathway is selectively abrogated while the capacity of ICOS to mobilize intracellular calcium remains intact, we have shown that ICOS mediated PI3K activation is required for some but not all T cell responses. This suggests that the ICOS-calcium signaling axis may explain some of the PI3K independent ICOS functions. Further, a recent in vivo imaging study indicated that ICOS-dependent intracellular calcium flux facilitates cognate T cell-B cell interactions within the germinal center. However, how ICOS promotes TCR-mediated calcium flux has not been clear. Here we identified a membrane proximal motif in the cytoplasmic tail of ICOS that is essential for ICOS-assisted calcium signaling and demonstrate that ICOS can induce calcium flux independently of other signaling motifs. We also provide evidence that ICOS potentiates phospholipase Cgamma1 (PLCgamma1) activation to enhance calcium release from the intracellular pool. In parallel, acute ligation of ICOS without TCR co-engagement leads to activation of small GTPases, RhoA and Cdc42, consistent with the capacity of ICOS to induce actin remodeling. Importantly, interruption of actin dynamics during acute TCR or TCR-ICOS co-ligation severely impairs calcium flux in T cells even in the presence of activated PLCgamma1. Thus, ICOS potentiates TCR-induced calcium flux by enhancing PLCgamma1 activation and actin remodeling in a coordinated manner. PMID- 27693915 TI - TLR9 played a more important role than TLR2 in the combination of maltose-binding protein and BCG-induced Th1 activation. AB - Our previous study demonstrated that maltose-binding protein (MBP) combined with BCG induced synergistic mouse Th1 activation in vivo. Here, to explore the mechanism of MBP combined with BCG on Th1 activation, mouse purified CD4+ T cells were stimulated with MBP and BCG in vitro. The results showed that MBP combined with BCG synergistically increased IFN-gamma production, accompanied with the upregulation of TLR2/9 expressions, suggesting that TLR2/9 were involved in the combination-induced Th1 activation. Next, TLR2 antibodies and TLR9 inhibitor were used to further analyze the effects of TLRs in Th1 activation. Results showed TLR2 antibody partly decreased MBP combined with BCG-induced IFN-gamma production, MyD88 expression and IkappaB phosphorylation, indicating that TLR2 mediated MyD88-dependent pathway was involved in the MBP combined with BCG induced Th1 activation. Moreover, MBP combined with BCG-induced Th1 activation was completely abrogated by TLR9 inhibitor, suggesting that TLR9-mediated MyD88 dependent pathway played a more important role than TLR2 in the combination induced Th1 activation. Further study showed that TLR9 inhibitor downregulated TLR2 expression, suggesting that TLR9 signaling regulated TLR2 activation to favor Th1 resonse induced by MBP combined with BCG. Collectively, we demonstrated for the first time that the cross-talk of TLR2 and TLR9 triggered Th1 activation collaboratively and our findings provided valuable information about designing more effective adjuvant for cancer therapy. PMID- 27693917 TI - T-cell clones from Th1, Th17 or Th1/17 lineages and their signature cytokines have different capacity to activate endothelial cells or synoviocytes. AB - OBJECTIVE: To compare the direct effect of cytokines on synoviocytes and endothelial cells to the effects of supernatants from Th1, Th17 and Th1/17 clones and the direct cell-cell interactions with the same clones. METHODS: Th17 and Th1/17 clones were obtained from the CD161+CCR6+ fraction and Th1 clones from the CD161-CCR6- fraction of human CD4+ T-cells. Endothelial cells or synoviocytes were cultured in the presence of either isolated pro-inflammatory cytokines (IL 17 and/or TNF-alpha) or supernatants from the T-cell clones or co-cultured with T cell clones themselves. IL-6 and IL-8 expression and production were analyzed. RESULTS: IL-17 and TNF-alpha induced IL-6 and IL-8 expression, although IL-17 alone had a limited effect on endothelial cells compared to synoviocytes. Supernatants from activated T-helper clones also induced IL-6 and IL-8 expression but with discrepancies between endothelial cells and synoviocytes. Endothelial cells were mostly activated by Th1 clone supernatants whereas synoviocytes were activated by all T-cell subtypes. Finally, cell-cell contact experiments showed a great heterogeneity among cell clones, even from the same lineage. IL-6 expression was mostly induced by contact with Th1 clones both in endothelial and mesenchymal cells whereas IL-8 expression was induced by all T-cell clones whatever their phenotype. CONCLUSION: We showed that endothelial cells were much more sensitive to Th1 activation whereas synoviocytes were activated by all T helper lineages. This work highlights the heterogeneity of interactions between T cells and stromal cells through soluble factors or direct cell contact. PMID- 27693918 TI - Identification of heat shock protein A9 as a Tembusu virus binding protein on DF 1 cells. AB - This study attempts to identify receptor elements for Tembusu virus (TMUV) on DF 1 cells. Using co-immunoprecipitation and virus overlay protein binding assays, we identified a TMUV-binding protein of approximately 70-kDa on DF-1 cell membranes. Mass spectroscopy identified the protein to be heat shock protein (HSP) A9, which was reconfirmed by an anti-HSPA9 antibody. Indirect immunofluorescence demonstrated a significant degree of colocalization between HSPA9 and TMUV on cell surface. Additionally, an antibody against HSPA9 could inhibit TMUV infection in DF-1 cells in a dose-dependent manner. These results might suggest that HSPA9 is a putative receptor for TMUV. PMID- 27693920 TI - The stress granule component G3BP is a novel interaction partner for the nuclear shuttle proteins of the nanovirus pea necrotic yellow dwarf virus and geminivirus abutilon mosaic virus. AB - Stress granules (SGs) are structures within cells that regulate gene expression during stress response, e.g. viral infection. In mammalian cells assembly of SGs is dependent on the Ras-GAP SH3-domain-binding protein (G3BP). The C-terminal domain of the viral nonstructural protein 3 (nsP3) of Semliki Forest virus (SFV) forms a complex with mammalian G3BP and sequesters it into viral RNA replication complexes in a manner that inhibits the formation of SGs. The binding domain of nsP3 to HsG3BP was mapped to two tandem 'FGDF' repeat motifs close to the C terminus of the viral proteins. It was speculated that plant viruses employ a similar strategy to inhibit SG function. This study identifies an Arabidopsis thaliana NTF2-RRM domain-containing protein as a G3BP-like protein (AtG3BP), which localizes to plant SGs. Moreover, the nuclear shuttle protein (NSP) of the begomovirus abutilon mosaic virus (AbMV), which harbors a 'FVSF'-motif at its C terminal end, interacts with the AtG3BP-like protein, as does the 'FNGSF'-motif containing NSP of pea necrotic yellow dwarf virus (PNYDV), a member of the Nanoviridae family. We therefore propose that SG formation upon stress is conserved between mammalian and plant cells and that plant viruses may follow a similar strategy to inhibit plant SG function as it has been shown for their mammalian counterparts.

AB - Mitigation of cassava mosaic disease (CMD) focuses on the introgression of resistance imparted by the polygenic recessive (CMD1), dominant monogenic (CMD2) and CMD3 loci. The mechanism(s) of resistance they impart, however, remain unknown. Two CMD susceptible and nine CMD resistant cassava genotypes were inoculated by microparticle bombardment with infectious clones of African cassava mosaic virus Cameroon strain (ACMV-CM) and the Kenyan strain K201 of East African cassava mosaic virus (EACMV KE2 [K201]). Genotypes carrying the CMD1 (TMS 30572), CMD2 (TME 3, TME 204 and Oko-iyawo) and CMD3 (TMS 97/0505) resistance mechanisms showed high levels of resistance to ACMV-CM, with viral DNA undetectable by PCR beyond 7days post inoculation (dpi). In contrast, all genotypes initially developed severe CMD symptoms and accumulated high virus titers after inoculation with EACMV KE2 (K201). Resistant genotypes recovered to become asymptomatic by 65dpi with no detectable virus in newly formed leaves. Genotype TMS 97/2205 showed highest resistance to EACMV KE2 (K201) with <30% of inoculated plants developing symptoms followed by complete recovery by 35dpi. Deep sequencing of small RNAs confirmed production of 21-24 nt virus derived small RNAs (vsRNA) that mapped to cover the entire ACMV-CM and EACMV KE2 (K201) viral genomes in both polarities, with hotspots seen within gene coding regions. In resistant genotypes, total vsRNAs were most abundant at 20 and 35dpi but reduced significantly upon recovery from CMD. In contrast, CMD susceptible genotypes displayed abundant vsRNAs throughout the experimental period. The percentage of vsRNAs reads ranked by class size were 21nt (45%), 22 nt (28%) and 24 nt (18%) in all genotypes studied. The number of vsRNA reads directly correlated with virus titer and CMD symptoms. PMID- 27693921 TI - Can the Functional Movement ScreenTM be used to capture changes in spine and knee motion control following 12 weeks of training? AB - OBJECTIVE: To examine whether objective measures of spine and frontal plane knee motion exhibited during Functional Movement ScreenTM (FMS) task performance changed following a movement-guided fitness (MOV) and conventional fitness (FIT) exercise intervention. DESIGN: Secondary analysis of a randomized controlled experiment. Before and after 12 weeks of exercise, participants' kinematics were quantified while performing the FMS and a series of general whole-body movement tasks. SETTING: Biomechanics laboratory. PARTICIPANTS: Fifty-two firefighters were assigned to MOV, FIT, or a control (CON) group. OUTCOME MEASURES: Peak lumbar spine flexion/extension, lateral bend and axial twist, and frontal plane knee motion. RESULTS: The post-training kinematic changes exhibited by trainees while performing the FMS tasks were similar in magnitude (effect size < 0.8) to those exhibited by CON. However, when performing the battery of general whole body movement tasks, only MOV showed significant improvements in spine and frontal plane knee motion control (effect size > 0.5). CONCLUSIONS: Whether graded qualitatively, or quantitatively via kinematic analyses, the FMS may not be a viable tool to detect movement-based exercise adaptations. Amendments to the FMS tasks and/or scoring method are needed before it can be used for reasons beyond appraising the ability to move freely, symmetrically, and without pain. PMID- 27693922 TI - Biological function analysis of monoclonal antibodies against human granulins in vitro using U251 cells as a model. AB - Progranulin (PGRN), a highly glycosylated, secreted 593 amino acid precursor protein, is a multifunctional molecule that is critical for early embryogenesis, wound repair, inflammatory and tumorigenesis. PGRN can be proteolytically cleaved into seven cysteine-rich granulin (Grn) peptides: G, F, B, A, C, D and E. Both PGRN and its constituent Grn peptides have been implicated in a wide variety of biological activities. However, their functions are far from clear, and the lack of granulin domain-specific antibodies has hindered the progress of the functional study of PGRN and Grns. Monoclonal antibodies against GrnB, GrnA, GrnC and GrnF have been previously developed by our laboratory. In this study, we generated monoclonal antibodies (MAbs) against GrnD, GrnG and GrnE by using recombinant proteins HSA-GrnG, HSA-GrnD and HSA-GrnE as immunogens, and characterized them by indirect ELISA, Western blot and immunocytochemistry. Furthermore, the neutralizing activities of the MAbs against seven Grns were tested in vitro using the U251 cell line. This full antibody panel of MAbs against seven Grns will be a valuable tool for elucidating the biological roles of PGRN and Grns in different physiopathological processes, which will further promote the development of PGRN-based clinical diagnosis and therapy. PMID- 27693923 TI - Potential health risk assessment of potato (Solanum tuberosum L.) grown on metal contaminated soils in the central zone of Punjab, Pakistan. AB - Metal buildup was estimated in potato (Solanum tuberosum L.), grown in central Punjab, Pakistan. This crop was irrigated with multiple water sources like ground, sewage and canal water. Concentrations of different metals like zinc (Zn), arsenic (As), lead (Pb), iron (Fe), nickel (Ni), molybdenum (Mo), copper (Cu), and selenium (Se) were assessed in the potato crop irrigated with different types of waters. Sewage water treated crop and soil had higher metal concentrations than those treated with other two treatments. All metals had positive and significant correlation except for Mo which was non-significantly correlated between the vegetable and soil. Highest daily intake was observed for Fe (0.267), whereas the lowest was seen for Se (0.003). The enrichment factor and health index varied between 0.135-15.08 and 0.285-83.77, respectively. This study concludes that vegetables cultivated on soil treated with sewage water is a potent threat for human health as the metals manifest toxicity after entering the food chain. PMID- 27693924 TI - Validation of a cage implant system for assessing in vivo performance of long acting release microspheres. AB - Here we describe development of a silicone rubber/stainless steel mesh cage implant system, much like that used to assess biocompatibility of biomaterials [1], for easy removal of injectable polymer microspheres in vivo. The sterile cage has a type 316 stainless steel mesh size (38 MUm) large enough for cell penetration and free fluid flow in vivo but small enough for microsphere retention, and a silicone rubber shell for injection of the microspheres. Two model drugs, the poorly soluble steroid, triamcinolone acetonide, and the highly water-soluble luteinizing hormone-releasing hormone (LHRH) peptide superagonist, leuprolide, were encapsulated in PLGA microspheres large enough (63-90 MUm) to be restrained by the cage implant in vivo. The in vitro release from both formulations was followed by ultra-performance liquid chromatography (UPLC) with and without the cage in a standard release media, PBS pH 7.4 + 0.02% Tween 80 + 0.05% sodium azide, at 37 degrees C. Pharmacokinetics (PK) in rats was assessed after SC injection or SC in-cage implantation of microspheres with plasma analysis by LC-MS/MS or EIA. Tr-A and leuprolide in vitro release was largely unaffected after the initial burst irrespective of the cage or test tube incubation vessel and release was much slower than observed in vivo for both drugs. Moreover, Tr-A and leuprolide pharmacokinetics with and without the cage were highly similar during the 2-3 week release duration before a significant inflammatory response was caused by the cage implant. Hence, the PK-validated cage implant provides a simple means to recover and evaluate the microsphere drug carriers in vivo during a time window of at least a few weeks in order to characterize the polymer microsphere release and erosion behavior in vivo. This approach may facilitate development of mechanism-based in vitro/in vivo correlations and enable development of more accurate and useful in vitro release tests. PMID- 27693925 TI - Low serum prealbumin levels in post-stroke depression. AB - Previous studies have shown that prealbumin is associated with depression. However, the association between prealbumin and post-stroke depression remains unelucidated. This observational cohort study determined whether low baseline serum prealbumin could predict post-stroke depression at 1 month in patients admitted with acute stroke. The study, conducted from October 2013 to September 2014, included 307 patients with acute stroke who were followed-up for 1 month. Serum prealbumin was measured within 24h after admission using an immunoturbidimetric method. The17-item Hamilton Depression Scale was used to evaluate depression symptoms. Patients with a depression score of >=7 were evaluated using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th edition, for diagnosing post-stroke depression at 1 month. Binary logistic regression analysis was used to evaluate possible predictors of post-stroke depression. Overall, 93 (30.3%) patients were diagnosed with post-stroke depression. Serum prealbumin was significantly lower in patients with versus those without post-stroke depression, and was a significant predictor of post-stroke depression after adjusting for confounding risk factors. In conclusion, baseline serum prealbumin level was associated with post-stroke depression at 1 month, suggesting that prealbumin might be a useful biomarker for post-stroke depression. PMID- 27693926 TI - The genomic content and context of auxiliary metabolic genes in marine cyanomyoviruses. AB - Viruses of marine cyanobacteria frequently contain auxiliary metabolic genes (AMGs) that augment host metabolism during infection, but little is known about their adaptive significance. We analyzed the distribution and genomic context of 33 AMGs across 60 cyanomyovirus genomes. Similarity in AMG content among cyanomyoviruses was only weakly correlated with phylogenetic relatedness; however, AMG content was generally conserved within the same operational taxonomic unit (OTU). A virus' AMG repertoire was also correlated with its isolation host and environment (coastal versus open ocean). A new analytical method based on shared co-linear blocks revealed that variation in the genomic location of an AMG was negatively correlated with its frequency across the genomes. We propose that rare AMGs are more frequently gained or lost as a result of fluctuating selection pressures, whereas common AMGs are associated with stable selection pressures. Finally, we describe a unique cyanomyovirus (S-CAM7) that lacks many AMGs including the photosynthesis gene psbA. PMID- 27693927 TI - The HPV16 E7 oncoprotein increases the expression of Oct3/4 and stemness-related genes and augments cell self-renewal. AB - Oct3/4 is a transcription factor involved in maintenance of the pluripotency and self-renewal of stem cells. The E7 oncoprotein and 17beta-estradiol (E2) are key factors in cervical carcinogenesis. In the present study, we aimed to investigate the effect of the HPV16 E7 oncoprotein and E2 on the expression pattern of Oct3/4, Sox2, Nanog and Fgf4. We also determined whether the E7 oncoprotein is associated with cell self-renewal. The results showed that Oct3/4, Sox2, Nanog and Fgf4 were upregulated by the E7 oncoprotein in vivo and in vitro and implicate E2 in the upregulation of these factors in vivo. We also demonstrated that E7 is involved in cell self-renewal, suggesting that the HPV16 E7 oncoprotein upregulates Oct3/4, Sox2, Nanog and Fgf4 expression to maintain the self-renewal capacity of cancer stem cells. PMID- 27693928 TI - Neuropeptide modulation of pattern-generating systems in crustaceans: comparative studies and approaches. AB - Central pattern generators are subject to modulation by peptides, allowing for flexibility in patterned output. Current techniques used to characterize peptides include mass spectrometry and transcriptomics. In recent years, hundreds of neuropeptides have been sequenced from crustaceans; mass spectrometry has been used to identify peptides and to determine their levels and locations, setting the stage for comparative studies investigating the physiological roles of peptides. Such studies suggest that there is some evolutionary conservation of function, but also divergence of function even within a species. With current baseline data, it should be possible to begin using comparative approaches to ask fundamental questions about why peptides are encoded the way that they are and how this affects nervous system function. PMID- 27693929 TI - Diagnostic values of ProSet magnetic resonance coronal source imaging for detecting symptomatic lesion in multiple lumbar foraminal stenosis. AB - OBJECTIVE: The aim of this study is to evaluate the values of ProSet magnetic resonance coronal source imaging (ProSet MR imaging) as a diagnostic tool for detecting symptomatic lesion in patients with multiple lumbar foraminal stenosis. PATIENTS AND METHODS: From January 2011 to June 2015, 46 patients with unilateral and single-level radiculopathy developed from foraminal stenosis were enrolled in the study. These diagnoses were confirmed with transforaminal selective nerve root block (SNRB) and electrophysiological testing, including electromyography and nerve conduction velocity (EMG/NCV) tests. The detection of symptomatic lesion among multiple lumbar foraminal stenosis was done by identification of spinal nerve swelling (NS) and/or running course abnormalities (RCA) observed on ProSet MR imaging. These results were compared with those from transforaminal SNRB testing and conventional MR imaging. Evaluations were performed blinded by two independent examiners. RESULTS: The diagnostic accuracy rates of the two examiners were 84.7% and 82.6% with a 0.835 kappa coefficient. NS (80.4%) showed a higher diagnostic accuracy rate compared to RCA (69.6%) for detecting symptomatic lesion. The presence or absence of both NS and RCA has a stronger relationship with symptomatic or non-symptomatic lesion compared to the relationship of either alone (p=0.00). CONCLUSION: ProSet MR imaging is a simple and helpful method for providing additional diagnostic accuracy to detect symptomatic lesion in patients with multiple foraminal stenosis. NS representing chemical radiculitis was more reliable diagnostic factor of ProSet MR imaging. PMID- 27693930 TI - To what extent is alcohol consumption associated with breast cancer recurrence and second primary breast cancer?: A systematic review. AB - BACKGROUND: The association between alcohol intake and breast cancer recurrence or development of second primary breast cancer in the survivor population is unclear. The aim of this systematic review was to evaluate the existing evidence to assess the extent to which alcohol consumption is associated with breast cancer recurrence and second primary breast cancer. METHODS: Six databases (Cochrane Library, EMBASE, MEDLINE, PubMed, Scopus and Web of Science) were searched using the following search phrase: (breast cancer OR breast adenocarcinoma OR breast neoplasm OR breast tumour) AND (alcohol* OR alcohol intake OR alcohol consumption OR ethanol) AND (recurrence OR second primary). A narrative synthesis was conducted on studies meeting the inclusion criteria. RESULTS: After screening, 16 studies met the inclusion criteria, of which 11 assessed breast cancer recurrence and 5 assessed second primary breast cancer. Considerable clinical and methodological heterogeneity was observed between studies. Approximately half of the included studies observed a modest, but significant, association between alcohol consumption and increased risk of breast cancer recurrence or development of a second primary breast cancer, with some studies observing associations from as little as six grams of alcohol intake per day. Two studies suggest this association was stronger in postmenopausal women. CONCLUSION: There is some evidence that alcohol consumption increases the risk of breast cancer recurrence, particularly in postmenopausal women. The association between alcohol and development of a second primary breast cancer is less clear. Inconsistencies in methodology and results across studies complicate attempts to develop a cohesive interpretation of findings. PMID- 27693931 TI - Mechanism of drug resistance in relation to site of metastasis: Meta-analyses of randomized controlled trials in advanced breast cancer according to anticancer strategy. AB - BACKGROUND: Breast cancer is heterogeneous at different levels: biologic subtypes, intratumoral areas, and sites of metastases. Randomized controlled trials (RCTs) classify metastatic sites as visceral or non-visceral, but this has little influence in treatment decisions, particularly in the absence of clinical urgency. Indeed, it is unclear if response to treatments differs among sites of metastases. PATIENTS AND METHODS: RCTs investigating 3 different anticancer strategies in metastatic breast cancer were identified: (1) new hormonal therapy, (2) new targeted therapies in hormone receptor positive tumours (everolimus or palbociclib), and (3) new anti-HER2 therapies. RCTs reporting hazard ratios (HR) for Progression Free Survival (PFS) and Overall Survival (OS) for sub-groups based on sites of metastases were weighted using generic inverse variance approach, and pooled in meta-analyses using Revman 5.3. Subgroup difference was tested with Chi2 statistics. RESULTS: Eleven RCTs (6701pts.) qualified. There was a significant difference in PFS between women with visceral versus non-visceral metastases when two endocrine strategies were compared, with benefits limited to women with visceral metastases [Pooled HR 0.85; 95% CI, 0.77-0.95 versus 1.02 (0.88-1.18) for non-visceral; p(difference)=0.05]. However, combination of an endocrine therapy and a targeted therapy was associated with better PFS compared to endocrine therapy alone for both groups [HR 0.51 (0.43-0.60) versus 0.45 (0.36 0.56) for non-visceral; p(difference)=0. 36]. Novel HER-2 targeted therapies were associated with significantly better PFS and OS only in visceral metastases [HR 0.59 (0.52-0.66) versus 0.71(0.44-1.13) for non-visceral, p(difference)=0.45, for PFS; and 0.64 (0.56-0.73) versus 0.82 (0.57=1.19) for non-visceral, p(difference)=0.20, for OS]. CONCLUSION: Combination of targeted agents and endocrine therapy results in concordant, superior PFS suggesting targetable endocrine resistance across metastatic sites. Discordant responses with endocrine strategy alone support use of targeted therapy, rather than change in endocrine agent at disease progression. HER2 targeted therapies may be less effective in areas of poor vascularization. PMID- 27693932 TI - Biological effects of plasma rich in growth factors (PRGF) on human endometrial fibroblasts. AB - OBJECTIVES: To evaluate the biological outcomes of plasma rich in growth factors (PRGF) on human endometrial fibroblasts in culture. STUDY DESIGN: PRGF was obtained from three healthy donors and human endometrial fibroblasts (HEF) were isolated from endometrial specimens from five healthy women. The effects of PRGF on cell proliferation and migration, secretion of vascular endothelial growth factor (VEGF), procollagen type I and hyaluronic acid (HA) and contractility of isolated and cultured human endometrial fibroblasts (HEF) were analyzed. Statistical analysis was performed in order to compare the effects of PRGF with respect to control situation (T-test or Mann-Whitney U-test). RESULTS: We report a significantly elevated human endometrial fibroblast proliferation and migration after treatment with PRGF. In addition, stimulation of HEF with PRGF induced an increased expression of the angiogenic factor VEGF and favored the endometrial matrix remodeling by the secretion of procollagen type I and HA and endometrial regeneration by elevating the contractility of HEF. These results were obtained for all PRGF donors and each endometrial cell line. CONCLUSIONS: The myriad of growth factors contained in PRGF promoted HEF proliferation, migration and synthesis of paracrine molecules apart from increasing their contractility potential. These preliminary results suggest that PRGF improves the biological activity of HEF in vitro, enhancing the regulation of several cellular processes implied in endometrial regeneration. This innovative treatment deserves further investigation for its potential in "in vivo" endometrial development and especially in human embryo implantation. PMID- 27693933 TI - Comparison of systemic and local methotrexate treatments in cesarean scar pregnancies: time to change conventional treatment and follow-up protocols. AB - OBJECTIVE: The aim of this study was to compare the use of systemic and local methotrexate in the treatment of cesarean scar pregnancy. STUDY DESIGN: In this retrospective cohort study, we collected the data of 44 patients with cesarean scar pregnancy. The patients were grouped according to treatment modality: Group 1, local methotrexate injection (n=17) and Group 2, systemic methotrexate (n=27). The groups were compared with respect to side effects, recovery time, reproductive outcome, and treatment cost. RESULTS: The mean gestational age at diagnosis (6.4+/-0.93 vs. 5.4+/-0.80 weeks, p=0.001), pretreatment serum beta human chorionic gonadotrophin level [27,970 (11,010-39,421) vs. 7606 (4725 16,996) mIU/mL, p=0.001], and lesion size (2.74+/-1.36 and 1.28+/-0.55cm, p=0.001) were higher in Group 1. All patients were cured by primary therapy without additional surgery. The mean times for beta-human chorionic gonadotrophin normalization, the uterine-mass disappearance, were significantly shorter in Group 1 than in Group 2 (6.17+/-1.55 vs. 8.11+/-2.0 weeks, p=0.001 and 10.47+/ 4.14 vs. 13.40+/-4.44 weeks, p=0.002, respectively). The cost of treatment was similar between groups (281.133+/-112.123$ vs. 551.134+/-131.792$, p=0.76). The total pregnancy rates were not different between groups (5/16, 31.4% vs. 6/11, 54.6%, p=0.301). One recurrent cesarean scar pregnancy occurred after systemic methotrexate. Oral ulcers, the most common side effect, were seen in seven patients in Group 2. CONCLUSION: Even though treatment success and reproductive outcomes are similar, local methotrexate is superior to systemic methotrexate with regard to recovery time, side effects, and treatment costs, even in patients with unfavorable pretreatment prognostic predictors. PMID- 27693934 TI - Cervical cancer screening after 50: near extinction? AB - OBJECTIVES: The objectives of this study were to determine the prevalence and predictors of Pap smear screening among women aged 50 years and older. STUDY DESIGN: This cross-sectional study was conducted at two large urban health centres in Selangor. A total of 515 women aged 50 and older were recruited. RESULTS: The mean age of the respondents was 58.83+/-7.05, with a range of 50- 83 years. The prevalence of Pap smear screening was 39.22% (n=202). From the multivariate analysis, Pap smear screening was significantly associated with health care provider advice (adjusted odds ratio (AOR)=18.75; 95% CI=8.30, 42.37); tertiary (AOR=11.26; 95% CI=1.50, 84.68) and secondary education level (AOR=9.47; 95% CI=1.43, 62.84); use of contraception (AOR=2.90; 95% CI=1.48, 5.69); heart disease (AOR=0.22; 95% CI=0.05, 0.97); and worry about Pap smear results (AOR=0.20; 95% CI=0.09, 0.42). CONCLUSION: The prevalence of Pap smear screening in the older women is unsatisfactory. Health care provider advice, education level, use of contraception, heart disease and worry about Pap smear results were predictors of undergoing Pap smear screening in this study population. PMID- 27693935 TI - Distribution of female genital tract anomalies in two classifications. AB - OBJECTIVE: This study assessed the distribution of Mullerian duct anomalies in two verified classifications of female genital tract malformations, and the presence of associated renal defects. STUDY DESIGN: 621 women with confirmed female genital tract anomalies were retrospectively grouped under the European (ESHRE/ESGE) and the American (AFS) classification. The diagnosis of uterine malformation was based on findings in hysterosalpingography, two-dimensional ultrasonography, endoscopies, laparotomy, cesarean section and magnetic resonance imaging in 97.3% of cases. Renal status was determined in 378 patients, including 5 with normal uterus and vagina. RESULTS: The European classification covered all 621 women studied. Uterine anomalies without cervical or vaginal anomaly were found in 302 (48.6%) patients. Uterine anomaly was associated with vaginal anomaly in 45.2%, and vaginal anomaly alone was found in 26 (4.2%) cases. Septate uterus was the most common (49.1%) of all genital tract anomalies, followed by bicorporeal uteri (18.2%). The American classification covered 590 (95%) out of the 621 women with genital tract anomalies. The American system did not take into account vaginal anomalies in 170 (34.7%) and cervical anomalies in 174 (35.5%) out of 490 cases with uterine malformations. Renal abnormalities were found in 71 (18.8%) out of 378 women, unilateral renal agenesis being the most common defect (12.2%), also found in 4 women without Mullerian duct anomaly. CONCLUSIONS: The European classification sufficiently covered uterine and vaginal abnormalities. The distribution of the main uterine anomalies was equal in both classifications. The American system missed cervical and vaginal anomalies associated with uterine anomalies. Evaluation of renal system is recommended for all patients with genital tract anomalies. PMID- 27693936 TI - Online health information on obesity in pregnancy: a systematic review. AB - OBJECTIVE: To assess the quality of health information available online for healthcare users on obesity in pregnancy and evaluate the role of the internet as an effective medium to advocate a healthy lifestyle in pregnancy. STUDY DESIGN: We used the poly-search engine Polymeta and complimented the results with Google searches (till July 2015) to identify relevant websites. All open access websites in English providing advice on the risks and management of obesity in pregnancy. Two independent reviewers assessed the quality of information provided in each of the included websites for credibility, accuracy, readability, content quality and technology. We compared websites 'quality according to their target population, health topic and source of funding'. RESULTS: Fifty-three websites were included. A third of websites were focused on obesity in pregnancy and two thirds targeted healthcare users. The median value for the overall credibility was 5/9, 7/12 for accuracy, 57.6/100 for readability, 45/80 for content quality and 75/100 for technology. Obesity specific websites provided lower credibility compared to general health websites (p=0.008). Websites targeting health users were easier to read (p=0.001). Non-governmental funded websites demonstrated higher content quality (p=0.005). Websites that are obesity focused, targeting health users and funded by non-governmental bodies demonstrated higher composite quality scores (p=0.048). CONCLUSIONS: Online information on obesity in pregnancy is varied. Governmental bodies in particular need to invest more efforts to improve the quality of online health information. PMID- 27693937 TI - Pelvic floor assessment after delivery: how should women be selected? AB - OBJECTIVE: Pelvic floor dysfunction after delivery is quite common. New mothers deserve to receive targeted care for pelvic floor dysfunction, but how should women who are at risk be identified and selected for treatment? This study investigated risk factors and puerperal health-seeking behaviours to develop a restrictive patient selection model for postpartum pelvic floor dysfunction assessment. STUDY DESIGN: This prospective observational study involved women who were at >=32 weeks gestational age when they delivered in a tertiary referral maternity hospital in Milan, Italy, between July and December 2014. Eligible women were scheduled for a 3-month postnatal pelvic floor clinic. The adherence rate to the pelvic floor clinic and the prevalence of pelvic floor dysfunctions at 3 months postpartum were recorded. Univariable and logistic multivariable analyses were performed to select risk factors for pelvic floor dysfunctions. Risk factors were then tested for sensitivity and specificity for 3-month postpartum pelvic floor dysfunctions. RESULTS: Of 1606 eligible women, 1293 (80.5%) were included in the analysis; 685 puerperal women (53.0%) adhered to the 3-month postnatal pelvic floor clinic; pelvic floor dysfunctions were detected in 238 women (34.7%). Four elements emerged as risk factors: symptoms before pregnancy (OR 1.72, 95% CI 1.15-2.56; p=0.008), symptoms during pregnancy (OR 2.13, 95% CI 1.49-3.06; p<0.0001), vacuum extractor use (OR 1.62, 95% CI 1.04 2.54; p=0.034), and severe perineal tears (OR 19.45, 95% CI 2.42-156.15; p=0.005). The combined sensitivity and specificity for the 4 risk factors were 82% and 39%, respectively. CONCLUSION: Internal risk factors analysis offers the potential to efficiently restrict patient selection for follow-up. PMID- 27693938 TI - Effect of IVF failure on quality of life and emotional status in infertile couples. AB - OBJECTIVE: To investigate the effect of a previous IVF failure on the quality of life and emotional distress, in couples undergoing IVF treatment. Experiencing IVF failure might cause differences on the anxiety-depression and quality of life scores of the couples, compared to the ones who were undergoing IVF treatment for the first time. STUDY DESIGN: This study included 64 couples who had previously experienced at least one IVF failure (Group 1) and 56 couples without history of IVF failure (Group 2) in a private Assisted Reproductive Center, Istanbul, Turkey. A sociodemographic data form, the FertiQoL International and Hospital Anxiety (HAD-A) and Depression scale (HAD-D) for evaluating the status of distress, were administered for the study. RESULT(S): FertiQoL scores were compared between the groups, the environment scale of the quality of life in treatment section was found to be significantly higher in Group 1 compared with Group 2 (p=0.009). The HAD-A and HAD-D scores did not differ significantly between the groups. Group-variables were investigated using multilevel analysis, the infertility duration and income level were found to have an effect on the subscales of quality of life (p=0.009 and p=0.001 respectively) in Group 2. Depression scores were higher in couples with infertility duration of below five years in Group 1 and Group 2 compared to couples with infertility duration of five years or above (MANOVA analysis). The level of education was found to affect the scores of HAD-D in Group 2, but not in Group 1 (p=0.011). The score of HAD-D was significantly affected by the family type only in Group 2 (p=0.009); the depression score of the couples living with a nuclear family was found to be higher compared with the couples living in a traditional family (p=0.021). CONCLUSION(S): Fertility-specific quality of life scores reveals better results regarding the orientation to the treatment environment in the couples with a previous IVF failure, compared to first IVF cycle couples. Treatment failure does not elevate the level of anxiety, while the effect on depression scores changes according to duration of infertility. PMID- 27693939 TI - Irreversible electroporation inhibits pro-cancer inflammatory signaling in triple negative breast cancer cells. AB - Low-level electric fields have been demonstrated to induce spatial re distribution of cell membrane receptors when applied for minutes or hours. However, there is limited literature on the influence on cell signaling with short transient high-amplitude pulses typically used in irreversible electroporation (IRE) for cancer treatment. Moreover, literature on signaling pertaining to immune cell trafficking after IRE is conflicting. We hypothesized that pulse parameters (field strength and exposure time) influence cell signaling and subsequently impact immune-cell trafficking. This hypothesis was tested in vitro on triple negative breast cancer cells treated with IRE, where the effects of pulse parameters on key cell signaling factors were investigated. Importantly, real time PCR mRNA measurements and ELISA protein analyses revealed that thymic stromal lymphopoietin (TSLP) signaling was down regulated by electric field strengths above a critical threshold, irrespective of exposure times spanning those typically used clinically. Comparison with other treatments (thermal shock, chemical poration, kinase inhibitors) revealed that IRE has a unique effect on TSLP. Because TSLP signaling has been demonstrated to drive pro-cancerous immune cell phenotypes in breast and pancreatic cancers, our finding motivates further investigation into the potential use of IRE for induction of an anti-tumor immune response in vivo.

AB - OBJECTIVE: Electroencephalogram (EEG) background reactivity is a reliable outcome predictor in cardiac arrest patients post therapeutic hypothermia. However, there is no consensus on modality testing and prior studies reveal only fair to moderate agreement rates. The aim of this study was to explore different stimulus modalities and report interrater agreements. METHODS: We studied a multicenter, prospectively collected cohort of cardiac arrest patients who underwent therapeutic hypothermia between September 2014 and December 2015. We identified patients with reactivity data and evaluated interrater agreements of different stimulus modalities tested in hypothermia and normothermia. RESULTS: Of the 60 patients studied, agreement rates were moderate to substantial during hypothermia and fair to moderate during normothermia. Bilateral nipple pressure is more sensitive (80%) when compared to other modalities in eliciting a reactive background in hypothermia. Auditory, nasal tickle, nailbed pressure and nipple pressure reactivity were associated with good outcomes in both hypothermia and normothermia. CONCLUSIONS: EEG reactivity varies depending on the stimulus testing modality as well as the temperature during which stimulation is performed, with nipple pressure emerging as the most sensitive during hypothermia for reactivity and outcome determination. SIGNIFICANCE: This highlights the importance of multiple stimulus testing modalities in EEG reactivity determination to reduce false negatives and optimize prognostication.

AB - In acquiring language, children must learn to appropriately place the different participants of an event (e.g., causal agent, affected entity) into the correct syntactic positions (e.g., subject, object) so that listeners will know who did what to whom. While many of these mappings can be characterized by broad generalizations, both within and across languages (e.g., semantic agents tend to be mapped onto syntactic subjects), not all verbs fit neatly into these generalizations. One particularly striking example is verbs of psychological state: The experiencer of the state can appear as either the subject (Agnes fears/hates/loves Bartholomew) or the direct object (Agnes frightens/angers/delights Bartholomew). The present studies explore whether this apparent variability in subject/object mapping may actually result from differences in these verbs' underlying meanings. Specifically, we suggest that verbs like fear describe a habitual attitude towards some entity whereas verbs like frighten describe an externally caused emotional episode. We find that this distinction systematically characterizes verbs in English, Mandarin, and Korean. This pattern is generalized to novel verbs by adults in English, Japanese, and Russian, and even by English-speaking children who are just beginning to acquire psych verbs. This results support a broad role for systematic mappings between semantics and syntax in language acquisition.

AB - Michael additions between carbohydrate derived nitroalkenes and several aliphatic and aromatic amines proceeded in a stereoselective way, leading to peracetylated 2-amino-1,2-dideoxy-1-nitro-heptitols. In addition, the antiproliferative activity of some of the new adducts has been studied. The results allowed to identify lead compounds which show GI50 values in the range 1.7-19MUM. PMID- 27693944 TI - In-vivo quantification of dynamic hip joint center errors and soft tissue artifact. AB - Hip joint center (HJC) measurement error can adversely affect predictions from biomechanical models. Soft tissue artifact (STA) may exacerbate HJC errors during dynamic motions. We quantified HJC error and the effect of STA in 11 young, asymptomatic adults during six activities. Subjects were imaged simultaneously with reflective skin markers (SM) and dual fluoroscopy (DF), an x-ray based technique with submillimeter accuracy that does not suffer from STA. Five HJCs were defined from locations of SM using three predictive (i.e., based on regression) and two functional methods; these calculations were repeated using the DF solutions. Hip joint center motion was analyzed during six degrees-of freedom (default) and three degrees-of-freedom hip joint kinematics. The position of the DF-measured femoral head center (FHC), served as the reference to calculate HJC error. The effect of STA was quantified with mean absolute deviation. HJC errors were (mean+/-SD) 16.6+/-8.4mm and 11.7+/-11.0mm using SM and DF solutions, respectively. HJC errors from SM measurements were all significantly different from the FHC in at least one anatomical direction during multiple activities. The mean absolute deviation of SM-based HJCs was 2.8+/ 0.7mm, which was greater than that for the FHC (0.6+/-0.1mm), suggesting that STA caused approximately 2.2mm of spurious HJC motion. Constraining the hip joint to three degrees-of-freedom led to approximately 3.1mm of spurious HJC motion. Our results indicate that STA-induced motion of the HJC contributes to the overall error, but inaccuracies inherent with predictive and functional methods appear to be a larger source of error. PMID- 27693945 TI - Repair genes expression profile of MLH1, MSH2 and ATM in the normal oral mucosa of chronic smokers. AB - OBJECTIVE: The aim of this study was to evaluate the effect of chronic smoking on the expression profile of the repair genes MLH1, MSH2 and ATM in the normal oral mucosa of chronic smokers and never smokers. MATERIALS AND METHODS: The sample consisted of thirty exfoliative cytology smears per group obtained from Smokers and Never Smokers. Total RNA was extracted and expression of the MLH1, MSH2 and ATM genes were evaluated by quantitative real-time and immunocytochemistry. The gene and protein expression data were correlated to the clinical data. Gene expression was analyzed statistically using the Student t-test and Pearson's correlation coefficient, with p<0.05. RESULTS: MLH1, MSH2 and ATM genes were downregulated in the smoking group compared to the control with significant values for MLH1 (p=0.006), MSH2 (p=0.0001) and ATM (p=0.0001). Immunocytochemical staining for anti-MLH1, anti-MSH2 and anti-ATM was negative in Never Smokers; in Smokers it was rarely positive. No significant correlation was observed among the expression of MLH1, MSH2, ATM and age, number of cigarettes consumed per day, time of smoking during life, smoking history or levels of CO in expired air. CONCLUSION: The expression of genes and proteins related to DNA repair mechanism MLH1, MSH2 and ATM in the normal oral mucosa of chronic smokers was reduced. PMID- 27693941 TI - Animal models of transcranial direct current stimulation: Methods and mechanisms. AB - The objective of this review is to summarize the contribution of animal research using direct current stimulation (DCS) to our understanding of the physiological effects of transcranial direct current stimulation (tDCS). We comprehensively address experimental methodology in animal studies, broadly classified as: (1) transcranial stimulation; (2) direct cortical stimulation in vivo and (3) in vitro models. In each case advantages and disadvantages for translational research are discussed including dose translation and the overarching "quasi uniform" assumption, which underpins translational relevance in all animal models of tDCS. Terminology such as anode, cathode, inward current, outward current, current density, electric field, and uniform are defined. Though we put key animal experiments spanning decades in perspective, our goal is not simply an exhaustive cataloging of relevant animal studies, but rather to put them in context of ongoing efforts to improve tDCS. Cellular targets, including excitatory neuronal somas, dendrites, axons, interneurons, glial cells, and endothelial cells are considered. We emphasize neurons are always depolarized and hyperpolarized such that effects of DCS on neuronal excitability can only be evaluated within subcellular regions of the neuron. Findings from animal studies on the effects of DCS on plasticity (LTP/LTD) and network oscillations are reviewed extensively. Any endogenous phenomena dependent on membrane potential changes are, in theory, susceptible to modulation by DCS. The relevance of morphological changes (galvanotropy) to tDCS is also considered, as we suggest microscopic migration of axon terminals or dendritic spines may be relevant during tDCS. A majority of clinical studies using tDCS employ a simplistic dose strategy where excitability is singularly increased or decreased under the anode and cathode, respectively. We discuss how this strategy, itself based on classic animal studies, cannot account for the complexity of normal and pathological brain function, and how recent studies have already indicated more sophisticated approaches are necessary. One tDCS theory regarding "functional targeting" suggests the specificity of tDCS effects are possible by modulating ongoing function (plasticity). Use of animal models of disease are summarized including pain, movement disorders, stroke, and epilepsy. PMID- 27693946 TI - Near-infrared light-triggered release of small molecules for controlled differentiation and long-term tracking of stem cells in vivo using upconversion nanoparticles. AB - Human mesenchymal stem cells (hMSCs) hold considerable potential for regenerative medicine, but their application is limited by the lack of an efficient method to control differentiation and track the migration of implanted cells in vivo. In this study, we developed a multifunctional nanocarrier based on upconversion nanoparticles (UCNPs) for controlling differentiation and long-term tracking of hMSCs. The UCNPs are conjugated with the peptide (Cys-Arg-Gly-Asp, CRGD) and the differentiation-inducing kartogenin (KGN) via a photocaged linker on the surface, and the obtained UCNP nanocarrier can be efficiently uptaken by hMSCs. Under the exposure of near-infrared (NIR) light, the upconverted UV emission from the UCNP nanocarrier leads to the photocleavage of the photocaged linker and intracellular release of KGN. The NIR-triggered release of KGN mediated by the UCNP nanocarrier efficiently induces chondrogenic differentiation of hMSCs in vitro with reduced KGN dosage compared to the conventional protocol of directly supplementing KGN in the media. Furthermore, NIR irradiation through the skin of living animals induces the chondrogenic differentiation of the subcutaneously implanted hMSCs treated with the KGN-laden UCNP nanocarrier, thereby enhancing neocartilage formation in vivo. Finally, the luminescent UCNP nanocarrier enables the long term tracking of the labeled hMSCs in vivo. We believe that our UCNP nanocarrier is a promising tool for the remote control of triggered delivery of inductive agents to stem cells at the prescribed time points and the elucidation of the function and the fate of the transplanted stem cells in vivo. PMID- 27693947 TI - Identification of non-resistant ROS-1 inhibitors using structure based pharmacophore analysis. AB - Proto-oncogene receptor tyrosine kinase ROS-1 plays a key role in regulating a variety of cancers mainly non-small cell lung cancer (NSCLC). The marketed ROS-1 inhibitors such as Crizotinib suffer from the tribulations of growing resistance due to mutations primarily Gly2032Arg in the ROS-1 protein. To curb the problem of resistance, researchers have developed inhibitors such as Lorlatinib against the mutant protein. The present study was designed to identify inhibitors against wild type (WT) as well as mutant ROS-1 protein that will offer a broader spectrum of activity. Exploring crystal structure of ROS-1 complexed with Lorlatinib, receptor-ligand pharmacophore model was developed using Discovery Studio (DS) software. The developed pharmacophore model consisted of one hydrogen bond acceptor (HBA), one hydrogen bond donor (HBD) and two hydrophobic features (HY), subsequently utilized for virtual screening of commercially available databases and the retrieved hits were further subjected to fitness score and Lipinski's filter. Thereafter, the retrieved hits were docked in WT and mutated (Gly2032Arg) proteins of ROS-1. Total five molecules were retrieved with good docking scores and good binding interactions within the active site of WT and mutated ROS-1. The binding energies of the ligand-receptor complexes were predicted via calculation of MM-GBSA score. To predict the stability of the ligand receptor complexes with mutant and wild type proteins, molecular dynamic simulation was performed. Thus, these identified hits show good binding affinities with WT and mutant ROS-1 proteins that may be further evaluated for their in-vitro/in-vivo activity. PMID- 27693948 TI - Molecular simulation study on concentration effects of rofecoxib with POPC bilayer. AB - The interactions between rofecoxib and POPC (1-palmitoyl-2-oleoyl-sn-glycero-3 phosphocholine) bilayer were studied using all-atom molecular dynamics simulation method. Four POPC bilayer systems with different number of rofecoxib molecules were constructed to simulate different drug concentration. The free energy of rofecoxib passing across pure POPC bilayer has two minima (at z ~1.2nm or 1.6nm). As for the high concentration model, the minimum of the free energy profile slightly shifts to the bilayer center. Moreover, the energy change from bulk water to POPC bilayer increases while the central barrier to cross the hydrophobic core of bilayer slightly decreases, suggesting that increasing drug concentration makes it favorable for rofecoxib to partition into the bilayer and easier to pass across bialyer center. Energy analysis show that the stabilization between the selected rofecoxib and other pre-inserted rofecoxib molecule is mainly due to van der Waals interaction energy. The predicted permeability of rofecoxib in high concentration model slightly weakens as compared with low concentration model. PMID- 27693949 TI - Persons with latent autoimmune diabetes in adults express higher dipeptidyl peptidase-4 activity compared to persons with type 2 and type 1 diabetes. AB - AIMS: We aimed to determine serum dipeptidyl peptidase-4 (DPP-4) activity in a group of persons with latent autoimmune diabetes in adults (LADA) and to compare it with persons with type 1, type 2 diabetes and healthy controls. METHODS: DPP-4 activity measurement was performed in 67 persons (21 with type 1, 26 type 2 and 19 with LADA) and 13 healthy age and gender matched controls. RESULTS: Persons with LADA showed highest DPP-4 activity among the study groups (32.71+/-3.55 vs 25.37+/-2.84 vs 18.57+/-2.54 vs 18.57+/-2.61U/L p<0.001). Mean glutamic acid autoantibody in persons with LADA was 164.32+/-86.28IU/mL. It correlated with DPP 4 activity (r=0.484, p=0.013). Furthermore, DPP-4 activity correlated with waist circumference (r=0.279, p=0.034) and glycated haemoglobin A1c (r=0.483, p<0.001), as well as with LDL cholesterol (r=0.854, p<0.001) and total daily insulin dose (r=0.397, p=0.001). In the multinomial regression analysis DPP-4 activity remained associated with both LADA (prevalence ratio 1.058 (1.012-1.287), p=0.001) and type 1 diabetes (prevalence ratio 1.506 (1.335-1.765), p<0.001) while it did not show an association with type 2 diabetes (prevalence ratio 0.942 (0.713-1.988), p=0.564). CONCLUSIONS: Persons with LADA express higher DPP-4 activity compared to persons with both type 1 and type 2 diabetes. The possible pathophysiological role of DPP-4 in the LADA pathogenesis needs to be further evaluated. PMID- 27693950 TI - Blood-based immune-endocrine biomarkers of treatment response in depression. AB - Antidepressant treatment for major depressive disorder remains suboptimal with response rates of just over 50%. Although treatment guidelines, algorithms and clinical keys are available to assist the clinician, the process of finding an effective pharmacotherapy to maximise benefit for the individual patient is largely by "trial and error" and remains challenging. This highlights a clear need to identify biomarkers of treatment response to help guide personalised treatment strategies. We have carried out the largest multiplex immunoassay based longitudinal study to date, examining up to 258 serum markers involved in immune, endocrine and metabolic processes as potential biomarkers associated with treatment response in 332 depression patients recruited from four independent clinical centres. We demonstrated for the first time that circulating Apolipoprotein A-IV, Endoglin, Intercellular Adhesion Molecule 1, Tissue Inhibitor of Metalloproteinases 1, Plasminogen Activator Inhibitor 1, Thrombopoietin, Complement C3, Hepatocyte Growth Factor and Insulin-like Growth Factor-Binding Protein 2 were associated with response to different antidepressants. In addition, we showed that specific sets of immune-endocrine proteins were associated with response to Venlafaxine (serotonin-norepinephrine reuptake inhibitor), Imipramine (tricyclic antidepressant) and other antidepressant drugs. However, we were not able to reproduce the literature findings on BDNF and TNF-alpha, two of the most commonly reported candidate treatment response markers. Despite the need for extensive validation studies, our preliminary findings suggest that a pre-treatment immune-endocrine profile may help to determine a patient's likelihood to respond to specific antidepressant and/or alternative treatments such as anti-inflammatory drugs, providing hope for future personalised treatment approaches. PMID- 27693951 TI - Quality assessment of marketed chamomile tea products by a validated HPTLC method combined with multivariate analysis. AB - Chamomile tea composed of dried flower heads of Matricaria recutita L. (Asteraceae) is one of the most popular single ingredient herbal teas. Tea industries, spice shops or public bazaars are mostly supplied chamomile as a raw material via cultivation or through nature-picking. However, one of the drawbacks of nature-picking is adulteration. This could be either due to false authentication of the plant materials by ingenuous pickers or intentional/unintentional substitution with other flowers resembling to chamomile in appearance during harvesting. Therefore, quality control of raw chamomile materials before marketing should be carefully considered not only by quantification of apigenin 7-O-glucoside (active marker) but also by fingerprinting of chemical composition. This work presents both quantification of apigenin 7-O-glucoside and chemical fingerprinting of commercial chamomile tea products obtained from different food stores and spice shops by a validated HPTLC method. In addition, HPTLC profiles of investigated chamomile tea samples were compared with HPLC method stated in the European Pharmacopoeia and it was found that HPTLC method was superior to HPLC method in the field of adulteration confirmation. Therefore, fingerprint profiles performed on the silica gel 60 NH2 F254s HPTLC plates combined with pattern recognition techniques of these marketed products were comparatively evaluated with wild and cultivar chamomile samples and also chamomile-like species from Asteraceae. Consequently, not chamomile tea bags but crude flowers sold on market were found to be adulterated with other plant materials. PMID- 27693952 TI - Simultaneous quantification and identification of flavonoids, lignans, coumarin and amides in leaves of Zanthoxylum armatum using UPLC-DAD-ESI-QTOF-MS/MS. AB - The current study presents isolation and characterization of twelve compounds including catechin (1), isovitexin (2), hesperidin (3), psoralin (4), eudesmin (5), kobusin (6), fargesin (7), sesamin (8), asarinin (9), planispine-A (10), alpha-sanshool (11) and vitexin (12), from the leaves of Zanthoxylum armatum. Further, two rapid and simple ultra performance liquid chromatography-diode array detection (UPLC-DAD) methods were developed for the simultaneous quantitative determination of isolated compounds from Z. armatum leaves. These analytical methods were validated for linearity, precision, accuracy, limit of detection (LOD) and limit of quantification (LOQ). The LOD and LOQ were in the range of 0.06-0.21MUg/mL and 0.19-0.69MUg/mL, respectively. The validated method was linear (R2>=0.9906), precise in terms of peak area (intra-day RSDs <3.8% and inter-day RSDs <2.7%), and accurate (109.6-92.5%). This is the first report on the isolation and quantification of 1, 2, 4 and 12 in Z. armatum and 3 in Zanthoxylum genus. The methods: were successfully applied to assess the quality of samples collected from different locations of Himachal Pradesh during summer and winter season. The results demonstrated that flavonoids and furofuran lignans were the major constituents in Z. armatum leaves. The developed methods: were further applied for tandem electrospray ionization-mass spectrometry (UPLC-DAD ESI-MS/MS) and total eighteen compounds were identified including phenolic acid, flavonoids, furofuran lignans, coumarin and isobutyl amides. PMID- 27693953 TI - Quantitative determination of xanthorrhizol in rat plasma by HPLC-MS/MS and its application to a pharmacokinetic study. AB - Although xanthorrhizol, a sesquiterpenoid oil isolated from the rhizoma of Curcuma xanthorrhiza Roxb. known as Java turmeric, represents a variety of pharmacological activities, to date, there have been no validated determination methods of xanthorrhizol in biological samples. Thus, we developed a liquid chromatographic method using a tandem mass spectrometry for the determination of xanthorrhizol in rat plasma. After simple protein precipitation with acetonitrile including diclofenac (internal standard, IS), the analytes were chromatographed on a reversed-phased column with a mobile phase of 20mM ammonium acetate aqueous solution and acetonitrile (20:80, v/v). The ion transitions of the precursor to the product ion were principally deprotonated ions [M-H]- at m/z 216.9->132.8 for xanthorrhizol and 296.1->251.7 for the IS. The accuracy and precision of the assay were in accordance with FDA regulations for the validation of bioanalytical methods. This analytical method was successfully applied to monitor plasma concentrations of xanthorrhizol over time following intravenous administration in rats.

AB - Nicotine-diet interactions have a particular importance on human health. Some food substances are subject to change hepatic CYP2A6 metabolism rate for nicotine and its levels in smokers consequently. This study investigates the effect of pomegranate and licorice drinks on nicotine metabolism, by a new developed and validated method for simultaneous determination of nicotine with its major metabolites (cotinine and nicotine N-oxide) in human urine, utilizing LC ESI orbitrap-MS. Twenty-four Jordanian healthy and smoker volunteers were participated in two equal groups, crossover design for each of pomegranate and licorice test drink. In the study periods each group assigned either to drink test juice three times a day or to be avoided from test drink for 7 successive days, and then both groups switched their drink treatment in subsequent period. Early morning urine samples were collected from all volunteers after each period. Nicotine metabolism rate was evaluated from nicotine/cotinine and nicotine/nicotine N-oxide ratios in urine. A consistent trend of increase in metabolism rate for nicotine was observed from urine analysis under pomegranate or licorice drink conditions compared to control conditions. Pomegranate and licorice drinks are increasing the metabolism rate for nicotine in terms of induction effect for hepatic cytochrome p450 enzymes. PMID- 27693955 TI - Four-way-leaning test shows larger limits of stability than a circular-leaning test. AB - INTRODUCTION: Limits of stability (LOS) have extensive clinical and rehabilitational value yet no standard consensus on measuring LOS exists. LOS measured using a leaning or a circling protocol is commonly used in research and clinical settings, however differences in protocols and reliability problems exist. OBJECTIVE: This study measured LOS using a four-way-leaning test and a circular-leaning test to test which showed larger LOS measurements. Furthermore, number of adaptation trials needed for consistent results was assessed. METHOD: Limits of stability were measured using a force plate (Metitur Good Balance System(r)) sampling at 50Hz. Thirty healthy subjects completed 30 trials assessing LOS alternating between four-way-leaning test and circular-leaning test. RESULTS: A main effect of methods (ANOVA:F(1,28)=45.86, P<0.01) with the four-way-leaning test showing larger values than the circular-leaning test (NK, P<0.01). An interaction between method*directions was found (ANOVA:F(3, 84)=24.87, P<0.01). The four-way-leaning test showed larger LOS in anterior (NK, P<0.05), right (NK, P<0.01) and left direction (NK, P<0.01). Analysis of LOS for the four-way-leaning test showed a difference between trials (ANOVA:F(14,392)=7.81, P<0.01). Differences were found between trial 1 and 7 (NK, P<0.03), trial 6 and 8 (NK, P<0.02) and trial 7 and 15 (NK, P<0.02). Four-way leaning test showed high correlation (ICC>0.87) between first and second trial for all directions. CONCLUSION: Four-way-leaning test yields larger LOS in anterior, right and left direction making it more reliable when measuring LOS. A learning effect was found up to the 8th trial, which suggests using 8 adaptation trials before reliable LOS is measured. PMID- 27693957 TI - Inter-session agreement and reliability of the Global Gait Asymmetry index in healthy adults. AB - There has been a growing effort in restoring gait symmetry in clinical conditions associated with pronounced gait asymmetry. A prerequisite to achieve this is that the chosen approach can accurately assess symmetry and detect/impose changes that exceed the natural day to day variability. Global symmetry indices are superior to local and discrete indices because they capture the patient's overall gait symmetry. However, their repeatability is unknown. This study assessed the inter session agreement and reliability of the Global Gait Asymmetry index. Twenty three healthy individuals participated in two 3D gait analyses, performed approximately one week apart. The 95% limits of agreement, standard error of measurement, smallest detectable change, and intraclass correlation coefficient were analysed. The obtained values showed this index has poor agreement and reliability between sessions. Therefore, it cannot be used to assess the patient's progress overtime nor to compare symmetry levels among groups. PMID- 27693956 TI - Validation of a commercial inertial sensor system for spatiotemporal gait measurements in children. AB - Although inertial sensor systems are becoming a popular tool for gait analysis in both healthy and pathological adult populations, there are currently no data on the validity of these systems for use with children. The purpose of this study was to validate spatiotemporal data from a commercial inertial sensor system (MobilityLab) in typically-developing children. Data from 10 children (5 males; 3.0-8.3 years, mean=5.1) were collected simultaneously from MobilityLab and 3D motion capture during gait at self-selected and fast walking speeds. Spatiotemporal parameters were compared between the two methods using a Bland Altman method. The results indicate that, while the temporal gait measurements were similar between the two systems, MobilityLab demonstrated a consistent bias with respect to measurement of the spatial data (stride length). This error is likely due to differences in relative leg length and gait characteristics in children compared to the MobilityLab adult reference population used to develop the stride length algorithm. A regression-based equation was developed based on the current data to correct the MobilityLab stride length output. The correction was based on leg length, stride time, and shank range-of-motion, each of which were independently associated with stride length. Once the correction was applied, all of the spatiotemporal parameters evaluated showed good agreement. The results of this study indicate that MobilityLab is a valid tool for gait analysis in typically-developing children. Further research is needed to determine the efficacy of this system for use in children suffering from pathologies that impact gait mechanics. PMID- 27693958 TI - Gait deficits in people with multiple sclerosis: A systematic review and meta analysis. AB - BACKGROUND: Multiple Sclerosis (MS) results in postural instability and gait abnormalities which are associated with accidental falls. OBJECTIVE: This systematic review and meta-analysis aims to quantify the effect of MS on gait to inform the development of falls prevention interventions. METHODS: A systematic literature search identified case-control studies investigating differences in gait variables between people with MS and healthy controls. Meta-analysis examined the effect of MS on gait under normal and fast paced conditions. RESULTS: Forty-one studies of people with Expanded Disability Status Scale (EDSS) 1.8 to 4.5 were included, of which 32 contributed to meta-analysis. A large effect of MS was found on stride length (Standardised Mean Difference, SMD=1.27, 95% CI{0.93, 1.61}), velocity (SMD=1.12, 95% CI{0.85, 1.39}), double support duration (SMD=0.85, 95% CI{0.51, 1.2}), step length (SMD=1.15, 95% CI{0.75, 1.5})and swing phase duration (SMD=1.23, 95% CI{0.06, 2.41}). A moderate effect was found on step width and stride time with the smallest effect found on cadence (SMD=0.43, 95% CI{0.14, 0.72}). All effect sizes increased for variables investigated under a fast walking pace condition (for example the effect on cadence increased to SMD=1.15, 95% CI{0.42, 1.88}). CONCLUSIONS: MS has a significant effect on gait even for those with relatively low EDSS. This effect is amplified when walking at faster speeds suggesting this condition may be more beneficial for assessment and treatment. No studies investigated the association between these deficits and falls. Further investigation relating to the predictive or protective nature of these deficits in relation to falls is warranted.

AB - Toxoplasmosis is a major public health issue, due to the presence of Toxoplasma gondii, mainly in pork. The aim of this study was to determine the occurrence of T. gondii in pigs and wild boars bred in different production systems in the Czech Republic using ELISA and qPCR methods. Our results show that T. gondii infection is widespread in pigs and wild boars bred and slaughtered in the Czech Republic and that there is a higher exposure to T. gondii in backyard slaughter operations and organic pig farming, indicating a potential risk for meat consumption. Additionally, genotyping of amplified loci for Type II suggests the presence of one clonal genotype circulating in these animals. PMID- 27693959 TI - Long-term effects of lateral wedge orthotics on hip and ankle joint space widths. AB - BACKGROUND: Lateral wedge insoles have been used for the treatment of medial knee osteoarthritis (OA) and have been shown to reduce loading of the medial compartment of the knee. However, as the entire lower extremity acts as a single kinetic chain, altering the biomechanics of the knee may also have significant effects at the ankles or hips. We aimed to evaluate the effects of lateral wedge orthotics on ankle and hip joints, compared to neutral orthotics, by assessing the changes in joint space width (JSW) during 36 months of continuous use. METHODS: We prospectively enrolled 109 subjects with symptomatic osteoarthritis of the medial knee according to the American College of Rheumatology criteria. The trial was double blind and patients were randomized to either wedged or neutral orthotic shoe inserts. Hip and ankle JSWs were quantified using plain radiographies at baseline and at 36-months follow-up. FINDINGS: 45 patients completed the 36 month study. 31 of those who completed the study were using the lateral wedge versus 14 were using neutral orthotics. 2 patients in the wedge group had missing radiographs and were not included in the JSW analyses. There were no significant differences between the wedge and the neutral orthotics groups in the magnitude of JSW change at either the hip or the ankles at 36 month. INTERPRETATION: We found no significant adverse effects of the lateral wedges on ankles or hips. (ClinicalTrials.gov NCT00076453). PMID- 27693962 TI - Effects of activin A and its downstream ERK1/2 in oxygen and glucose deprivation after isoflurane-induced postconditioning. AB - BACKGROUND: Isoflurane postconditioning (ISPOC) plays a neuroprotection role in the brain. Previous studies confirmed that isoflurane postconditioning can provide better protection than preconditioning in acute hypoxic-ischemic brain damage, such as acute craniocerebral trauma and ischemic stroke. Numerous studies have reported that activin A can protect rat's brain from cell injury. However, whether activin A and its downstream ERK1/2 were involved in isoflurane postconditioning-induced neuroprotection is unknown. METHODS: A total of 80 healthy Sprague-Dawley rats weighing 50-70g were randomly divided into 10 groups of 8: normal control, oxygen and glucose deprivation (OGD), 1.5% ISPOC, 3.0% ISPOC, 4.5% ISPOC, blocker of activin A (SB431542), blocker of ERK1/2 (U0126), 3.0% ISPOC+SB431542, 3.0% ISPOC+U0126, and vehicle (dimethyl sulfoxide(DMSO)) group. Blockers (SB431542 and U0126) were used in each concentration of isoflurane before OGD. Hematoxylin-eosin staining, 2,3,5-triphenyl tetrazolium chloride staining, and propidium iodide (PI) staining were conducted to assess the reliability in the brain slices. Immunofluorescence, Western blot, and quantitative real-time PCR(Q-PCR) were performed to validate the protein expression levels of activin A, Smad2/3, P-Smad2/3, ERK1/2, and phosphorylation ERK1/2 (P-ERK1/2). RESULTS: The number of damaged neurons and mean fluorescence intensity(MFI) of PI staining increased, but formazan generation, expression levels of activin A and P-ERK1/2 protein, and mRNA synthesis level of activin A decreased in the OGD group compared with the normal control group (p<0.05). The number of damaged neurons and MFI of PI staining decreased, but formazan production, expression levels of activin A, P-Smad2/3, and P-ERK1/2, and mRNA synthesis level of activin A increased significantly in the 1.5% ISPOC and 3.0% ISPOC groups (p<0.05) compared with the OGD group. The result in the 4.5% ISPOC group, was completely opposite to the 1.5% ISPOC and 3.0% ISPOC groups. The number of damage neuron and MFI of PI staining increased, but formazan production, expression levels of activin A, P-Smad2/3, and P-ERK1/2, and mRNA synthesis level of activin A decreased in the 4.5% ISPOC group. However, the expression levels of activin A, P-Smad2/3, and P-ERK1/2, and mRNA synthesis level of activin A in the 4.5% ISPOC group were higher than the OGD group (p<0.05). The other results were compared between the SB431542 group/the U0126 group and 3.0% ISPOC group. The MFI of PI staining increased, but the expression levels of activin A, P-Smad2/3, and P-ERK1/2 decreased (p<0.05). The expression level of ERK1/2 protein in all groups exhibited no change (p>0.05). CONCLUSION: Results of this study showed that 3.0% concentration of isoflurane postconditioning provided better neuroprotection than 1.5% and 4.5% concentrations of isoflurane. Activin A/Smad 2/3 and activin A/ERK1/2 signaling pathway may be involved in ISPOC induced neuroprotection. PMID- 27693963 TI - High glucose prevents osteogenic differentiation of mesenchymal stem cells via lncRNA AK028326/CXCL13 pathway. AB - BACKGROUND: High glucose (HG) often induces unfavorable effects on proliferation and differentiation of mesenchymal stem cells (MSCs). This study aimed to explore potential molecular pathways underlying HG functional mechanism during osteogenic differentiation of MSCs, involving lncRNA AK028326 and CXCL13. METHODS: Murine bone marrow-derived MSCs were cultured in osteogenic-inducing medium supplemented with high glucose level at 25mM or 5.5mM as normal control. Expression levels of lncRNA AK028326 and CXCL13 were measured by using real-time PCR. The mineralized nodule formation and alkaline phosphatase (ALP) activity were detected after 21 and 7days of incubation respectively. Western blot were also performed to determine the expression of CXCL13 and osteogenic gene markers. Plasmid pcDNAs and small interference RNAs were transfected as indicated for functional analysis of AK028326 and CXCL13. RESULTS: HG suppressed the expression of AK028326 and CXCL13 in MSCs in a time-dependent manner, and also the mineralization, ALP activity, and osteogenic gene expression, which could be reversed by overexpression of AK028326 or CXCL13. CXCL13 expression was positively regulated by AK028326 at both mRNA and protein levels. Moreover, CXCL13 mediated the positive regulation of AK028326 on osteogenic gene expression in MSCs and MC3T3 E1 cells, mineralization and ALP activity in MSCs and also HG-induced inhibitory effects during MSCs differentiation into osteoblast. CONCLUSION: HG could inhibit osteogenic differentiation of MSCs via inhibited expression of CXCL13 mediated by lncRNA AK028326, thereby providing new insights into the molecular mechanism of many osteogenesis-related diseases especially for patients with hyperglycemia. PMID- 27693961 TI - Molecular and cellular effects of vitamin B12 forms on human trophoblast cells in presence of excessive folate. AB - Folic acid (FA) and iron are essential supplements during pregnancy. Similarly effects of vitamin B12 (B12) inadequacy and high folate and low B12 status, on pregnancy outcome are available. However there are no mandatory recommendations for B12. There are many forms of B12 viz. Cyanocobalamin (Cbl), Methylcobalamin (MeCbl), Adenosylcobalamin (AdCbl), and Hydroxycobalamin (HCbl) though there is limited consensus on which form has better efficacy. In the present study we have determined effect of various forms of B12 in the presence of two FA concentrations namely normal physiological (20ng/mL; NPFA) and supra physiological (2000ng/mL; SPFA) concentration to mimic real time situation where FA is in excess due to supplementation. We assessed trophoblastic proliferation, viability, TNFalpha and EGFr mRNA expression, homocysteine, beta-hCG and MDA levels. Trophoblastic viability was significantly suppressed at SPFA concentration and was restored by B12 treatment with Cbl, AdCbl and combination of MeCbl+AdCbl. The mRNA expressions of TNFalpha were up-regulated, while EGFr were down-regulated at SPFA concentrations, as validated by RT-PCR. Treatment with MeCbl+AdCbl significantly decreased homocysteine and MDA levels at SPFA concentrations. High levels of FA alone had a detrimental effect on placental health and functions as reflected by decreased viability, EGFr expression and increased TNFalpha expression, homocysteine and MDA levels. Combination of B12 active forms i.e. MeCbl+AdCbl was found to be most effective in neutralising excess folate effect in-vitro.

AB - Signal enhancement by hyperpolarization is a way of overcoming the low sensitivity in magnetic resonance; MRI in particular. One of the most well-known methods, dissolution Dynamic Nuclear Polarization, has been used clinically in cancer patients. One way of ensuring a low bioburden of the hyperpolarized product is by use of a closed fluid path that constitutes a barrier to contamination. The fluid path can be filled with the pharmaceuticals, i.e. imaging agent and solvents, in a clean room, and then stored or immediately used at the polarizer. In this study, we present a method of filling the fluid path that allows it to be reused. The filling method has been investigated in terms of reproducibility at two extrema, high dose for patient use and low dose for rodent studies, using [1-13C]pyruvate as example. We demonstrate that the filling method allows high reproducibility of six quality control parameters with standard deviations 3-10 times smaller than the acceptance criteria intervals in clinical studies. PMID- 27693964 TI - Role of oral microbiome on oral cancers, a review. AB - The oral cavity is inhibited by many of the bacterial species. Some of them have a key role in the development of oral disease. Interrelationships between oral microbiome and systemic conditions such as head-and-neck cancer have become increasingly appreciated in recent years. Emerging evidence also suggests a link between periodontal disease and oral cancer, and the explanation being that chronic inflammation could be a major factor in both diseases. Squamous cell carcinoma is that the most frequently occurring malignancy of the oral cavity and adjacent sites, representing over 90% of all cancers. The incidence of oral cancer is increasing, significantly among young people and women. Worldwide there are 350,000-400,000 new cases diagnosed every year. Bacteria, viruses, and fungi are strongly implicated as etiological factors in certain cancers. In this review we will discuss the association between the development of oral cancer in potentially malignant oral lesions with chronic periodontitis, chronic Porphyromonas gingivalis, Fusobacterium nucleatum, candida, other microbes and described mechanisms which may be involved in these carcinoma. PMID- 27693966 TI - Scapular dyskinesis: Patterns, functional disability and associated factors in people with shoulder disorders. AB - BACKGROUND: Patterns of scapular dyskinesis have unique scapular kinematics and associated muscular activation. The characteristics of unique dyskinesis patterns may be associated with functional disability. OBJECTIVES: To investigate whether the shoulder function level and primary dysfunction items were different in unique dyskinesis pattern. The factors associated with shoulder dysfunction in different dyskinesis patterns were identified. DESIGN: Cross-sectional study. METHODS: Fifty-one participants with unilateral shoulder pain were classified as having a single dyskinesis pattern (inferior angle prominence, pattern I; medial border prominence, pattern II) or a mixed dyskinesis pattern (patterns I + II). Clinical measurements with the Flexilevel Scale of Shoulder Function (FLEX-SF), shoulder range of motion and pectoralis minor index were recorded. These clinical measurements, 3-D scapular kinematics (electromagnetic-based motion analysis), and associated muscular activation (electromyography on the upper/middle/lower trapezius and serratus anterior muscles) during arm elevation were analyzed for associations with functional disability. RESULTS: We found FLEX-SF scores and primary dysfunction items were similar among the patterns of dyskinesis. In inferior angle prominence, increased shoulder function was associated with decreased upper trapezius activity (R2 = 0.155, p = 0.035), which accounted for approximately 16% of the variance of FLEX-SF scores. In medial border prominence, increased shoulder function was associated with increased lower trapezius activity (R2 = 0.131, p = 0.017), which accounted for approximately 13% of the variance of FLEX-SF scores. CONCLUSION: Upper and lower trapezius activities are important to consider in the evaluation of patients with pattern I and II, respectively. No other factors were related to shoulder dysfunction due to insufficient challenge of arm elevation tasks. PMID- 27693967 TI - RNA-seq reveals differential gene expression in the brains of juvenile resident and migratory smolt rainbow trout (Oncorhynchus mykiss). AB - Many migratory traits are heritable, but there is a paucity of evidence identifying the molecular mechanisms underlying differentiation in alternative migratory tactics, or in linking variation in gene expression to migratory behaviors. To that end, we examined differential gene expression in the brain transcriptome between young steelhead trout that had undergone the smoltification process, and resident rainbow trout (Oncorhynchus mykiss) from Sashin Creek, Alaska. Samples were sequenced from two time points: immediately before (at 20months of age) and during (2years of age) the presumed peak of smoltification. Smolt and resident individuals came from two genetic crosses, one where both parents were migratory, and another where both parents were residents. A total of 533 (1.9%) genes were differentially expressed between crosses, or between smolt and resident samples. These genes include some candidate migratory genes (such as POMC), as well as genes with no previous known involvement in the migratory process. Progeny from resident parents showed more upregulated genes than progeny from migrant parents at both time points. Pathway analysis showed enrichment in 227 biological pathways between cross type, and 171 biological pathways were enriched between residents and smolts. Enriched pathways had connections to many biofunctions, and most were only enriched in one contrast. However, pathways connected to phototransduction were enriched between both cross type and migratory tactics in 11 out of 12 contrasts, suggesting there are fundamental differences in how smolts and residents process light in the brain. The genes and pathways described herein constitute an a priori candidate list for future studies of migration in other populations of O. mykiss, and other migratory species. PMID- 27693968 TI - Effects of water chemistry on decolorization in three photochemical processes: Pro and cons of the UV/AA process. AB - The poor selectivity of hydroxyl radicals is a major restriction in the practical application of the UV/H2O2 process for dyeing wastewater treatment. As an alternative, the target-selective UV/acetylacetone (AA) process was found highly efficient for dye decolorization. For the proper selection and application of the two photochemical processes, the effects of water matrices, including common inorganic anions (Cl-, SO42-, NO3-, HCO3-), natural organic matter, metal cations (Mg2+, Mn2+, Cu2+, Fe3+, Cr3+), and temperature, on the photo-degradation of an azo dye, Acid Orange 7 (AO7), were systematically investigated. The experimental results demonstrate that the UV/AA process was more sensitive to inner filter effect. NO3-, Cu2+, and Fe3+ were all detrimental to the UV/AA process, whereas at certain concentrations they were beneficial to the UV/H2O2 process. However, even with severe inhibitory effects, the decolorization efficiency of the UV/AA process was still several times higher than that of the UV/H2O2 process. The results are helpful for us to better understand the mechanisms behind the UV/AA process and may shed light on the application of UV-based advanced oxidation processes for wastewater treatment. PMID- 27693970 TI - Effects of current generation and electrolyte pH on reverse salt flux across thin film composite membrane in osmotic microbial fuel cells. AB - Osmotic microbial fuel cells (OsMFCs) take advantages of synergy between forward osmosis (FO) and microbial fuel cells (MFCs) to accomplish wastewater treatment, current generation, and high-quality water extraction. As an FO based technology, OsMFCs also encounter reverse salt flux (RSF) that is the backward transport of salt ions across the FO membrane into the treated wastewater. This RSF can reduce water flux, contaminate the treated wastewater, and increase the operational expense, and thus must be properly addressed before any possible applications. In this study, we aimed to understand the effects of current generation and electrolyte pH on RSF in an OsMFC. It was found that electricity generation could greatly inhibit RSF, which decreased from 16.3 +/- 2.8 to 3.9 +/- 0.7 gMH when the total Coulomb production increased from 0 to 311 C. The OsMFC exhibited 45.9 +/- 28.4% lower RSF at the catholyte pH of 3 than that at pH 11 when 40 Omega external resistance was connected. The amount of sodium ions transported across the FO membrane was 18.3-40.7% more than that of chloride ions. Ion transport was accomplished via diffusion and electrically-driven migration, and the theoretical analysis showed that the inhibited electrically-driven migration should be responsible for the reduced RSF. These findings are potentially important to control and reduce RSF in OsMFCs or other osmotic-driven processes. PMID- 27693969 TI - An activated carbon fiber cathode for the degradation of glyphosate in aqueous solutions by the Electro-Fenton mode: Optimal operational conditions and the deposition of iron on cathode on electrode reusability. AB - An activated carbon fiber (ACF) cathode was fabricated and used to treat glyphosate containing wastewater by the Electro-Fenton (EF) process. The results showed that glyphosate was rapidly and efficiently degraded and the BOD5/COD ratio was increased to >0.3 implying the feasibility of subsequent treatment of the treated wastewater by biological methods. The results of ion chromatography and HPLC measurements indicated that glyphosate was completely decomposed. Effective OH generation and rapid recycling/recovery of the Fe2+ ions at the cathode were responsible primarily for the high performance of the ACF-EF process. Factors such as inlet oxygen gas flow rate, Fe2+ dosage, initial glyphosate concentration, applied current intensity, and solution pH that may affect the efficiency of the ACF-EF process were further studied and the optimum operation condition was established. Results of SEM/EDX, BET and XPS analysis showed the deposition of highly dispersed fine Fe2O3 particles on the ACF surface during the EF reaction. The possibility of using the Fe2O3-ACF as iron source in the EF process was assessed. Results showed that the Fe2O3-ACF electrode was effective in degrading glyphosate in the EF process. The deposition of Fe2O3 particles on the ACF electrode had no adverse effect on the reusability of the ACF cathode. PMID- 27693971 TI - Differential decomposition of bacterial and viral fecal indicators in common human pollution types. AB - Understanding the decomposition of microorganisms associated with different human fecal pollution types is necessary for proper implementation of many water quality management practices, as well as predicting associated public health risks. Here, the decomposition of select cultivated and molecular indicators of fecal pollution originating from fresh human feces, septage, and primary effluent sewage in a subtropical marine environment was assessed over a six day period with an emphasis on the influence of ambient sunlight and indigenous microbiota. Ambient water mixed with each fecal pollution type was placed in dialysis bags and incubated in situ in a submersible aquatic mesocosm. Genetic and cultivated fecal indicators including fecal indicator bacteria (enterococci, E. coli, and Bacteroidales), coliphage (somatic and F+), Bacteroides fragilis phage (GB-124), and human-associated genetic indicators (HF183/BacR287 and HumM2) were measured in each sample. Simple linear regression assessing treatment trends in each pollution type over time showed significant decay (p <= 0.05) in most treatments for feces and sewage (27/28 and 32/40, respectively), compared to septage (6/26). A two-way analysis of variance of log10 reduction values for sewage and feces experiments indicated that treatments differentially impact survival of cultivated bacteria, cultivated phage, and genetic indicators. Findings suggest that sunlight is critical for phage decay, and indigenous microbiota play a lesser role. For bacterial cultivated and genetic indicators, the influence of indigenous microbiota varied by pollution type. This study offers new insights on the decomposition of common human fecal pollution types in a subtropical marine environment with important implications for water quality management applications. PMID- 27693972 TI - The environmental impact of sewage and wastewater outfalls in Antarctica: An example from Davis station, East Antarctica. AB - We present a comprehensive scientific assessment of the environmental impacts of an Antarctic wastewater ocean outfall, at Davis station in East Antarctica. We assessed the effectiveness of current wastewater treatment and disposal requirements under the Protocol on Environmental Protection to the Antarctic Treaty. Macerated wastewater has been discharged from an outfall at Davis since the failure of the secondary treatment plant in 2005. Water, sediment and wildlife were tested for presence of human enteric bacteria and antibiotic resistance mechanisms. Epibiotic and sediment macrofaunal communities were tested for differences between sites near the outfall and controls. Local fish were examined for evidence of histopathological abnormalities. Sediments, fish and gastropods were tested for uptake of sewage as measured by stable isotopes of N and C. Escherichia coli carrying antibiotic resistance determinants were found in water, sediments and wildlife (the filter feeding bivalve Laternula eliptica). Fish (Trematomus bernacchii) within close proximity to the outfall had significantly more severe and greater occurrences of histopathological abnormalities than at controls, consistent with exposure to sewage. There was significant enrichment of 15N in T. bernacchii and the predatory gastropod Neobuccinum eatoni around the outfall, providing evidence of uptake of sewage. There were significant differences between epibiotic and sediment macrofaunal communities at control and outfall sites (<1.5 km), when sites were separated into groups of similar habitat types. Benthic community composition was also strongly related to habitat and environmental drivers such as sea ice. The combined evidence indicated that the discharge of wastewater from the Davis outfall is causing environmental impacts. These findings suggest that conditions in Antarctic coastal locations, such as Davis, are unlikely to be conducive to initial dilution and rapid dispersal of wastewater as required under the Protocol on Environmental Protection to the Antarctic Treaty. Current minimum requirements for wastewater treatment and disposal in Antarctica are insufficient to ameliorate these risks and are likely to lead to accumulation of contaminants and introduction of non-native microbes and associated genetic elements. This new understanding suggests that modernised approaches to the treatment and disposal of wastewater are required in Antarctica. The most effective solution is advanced levels of wastewater treatment, which are now possible, feasible and a high priority for installation. As a direct outcome of the study, a new advanced treatment system is being installed at Davis, effectively avoiding environmental risks. PMID- 27693973 TI - Financing the HIV response in sub-Saharan Africa from domestic sources: Moving beyond a normative approach. AB - Despite optimism about the end of AIDS, the HIV response requires sustained financing into the future. Given flat-lining international aid, countries' willingness and ability to shoulder this responsibility will be central to access to HIV care. This paper examines the potential to expand public HIV financing, and the extent to which governments have been utilising these options. We develop and compare a normative and empirical approach. First, with data from the 14 most HIV-affected countries in sub-Saharan Africa, we estimate the potential increase in public HIV financing from economic growth, increased general revenue generation, greater health and HIV prioritisation, as well as from more unconventional and innovative sources, including borrowing, health-earmarked resources, efficiency gains, and complementary non-HIV investments. We then adopt a novel empirical approach to explore which options are most likely to translate into tangible public financing, based on cross-sectional econometric analyses of 92 low and middle-income country governments' most recent HIV expenditure between 2008 and 2012. If all fiscal sources were simultaneously leveraged in the next five years, public HIV spending in these 14 countries could increase from US$3.04 to US$10.84 billion per year. This could cover resource requirements in South Africa, Botswana, Namibia, Kenya, Nigeria, Ethiopia, and Swaziland, but not even half the requirements in the remaining countries. Our empirical results suggest that, in reality, even less fiscal space could be created (a reduction by over half) and only from more conventional sources. International financing may also crowd in public financing. Most HIV-affected lower-income countries in sub Saharan Africa will not be able to generate sufficient public resources for HIV in the medium-term, even if they take very bold measures. Considerable international financing will be required for years to come. HIV funders will need to engage with broader health and development financing to improve government revenue-raising and efficiencies. PMID- 27693974 TI - Promoting physical activity interventions in communities with poor health and socio-economic profiles: A process evaluation of the implementation of a new walking group scheme. AB - Walking groups have known health benefits but may not operate in communities with the greatest health needs, leading to the potential for increasing health inequity. This study examined the process of implementing a new volunteer led walking group scheme in a deprived community in England with poor physical activity, health and socio-economic indicators. Documentary evidence and semi structured interviews with stakeholders and volunteer walk leaders undertaken at the beginning and end of the funding period were analysed thematically. It was found that utilising community-based assets, forming collaborative partnerships with health and non-health organisations and ongoing sustainability issues were all factors that affected the scheme's effective implementation. Passive recruitment methods and mass publicity did not attract participants who were representative of their community. The findings firstly suggest the necessity of identifying and mobilising community based assets at the 'grass roots' in deprived communities during the preparatory stage to access those in greatest need and to plan and build capacity. Secondly, the findings highlight the key role that health professionals have in referring those in poorest health and the inactive into walking interventions. In the new era of fiscally constrained public health embedded within local authorities these findings are pertinent in supporting the utilisation of local assets to address entrenched physical inactivity and inequity within deprived communities. PMID- 27693975 TI - Valproate for agitation in critically ill patients: A retrospective study. AB - PURPOSE: The purpose was to describe the use of valproate therapy for agitation in critically ill patients, examine its safety, and describe its relationship with agitation and delirium. MATERIALS AND METHODS: This retrospective cohort study evaluated critically ill adults treated with valproate for agitation from December 2012 through February 2015. Information on valproate prescribing practices and safety was collected. Incidence of agitation, delirium, and concomitant psychoactive medication use was compared between valproate day 1 and valproate day 3. Concomitant psychoactive medication use was analyzed using mixed models. RESULTS: Fifty-three patients were evaluated. The median day of valproate therapy initiation was ICU day 7, and it was continued for a median of 7 days. The median maintenance dose was 1500 mg/d (23 mg/kg/d). The incidence of agitation (96% vs 61%, P < .0001) and delirium (68% vs 49%, P = .012) significantly decreased by valproate day 3. Treatment with opioids (77% vs 65%, P = .02) and dexmedetomidine (47% vs 24%, P = .004) also decreased. In mixed models analyses, valproate therapy was associated with reduced fentanyl equivalents ( 185 MUg/d, P = .0003) and lorazepam equivalents (-2.1 mg/d, P = .0004). Hyperammonemia (19%) and thrombocytopenia (13%) were the most commonly observed adverse effects. CONCLUSIONS: Valproate therapy was associated with a reduction in agitation, delirium, and concomitant psychoactive medication use within 48 hours of initiation. PMID- 27693976 TI - Cumulative arsenic exposure is associated with fungal infections: Two cohort studies based on southwestern and northeastern basins in Taiwan. AB - Long-term arsenic exposure results in atherosclerosis and cancers, along with aberrant immune responses. Animal-based and epidemiological studies indicate that arsenic exposure increases susceptibility to viral and bacterial infections. This study aimed to assess whether arsenic exposure is associated with the development of fungal infection, which is substantially attributed to as a cause of aberrant immunity. Based on two well-established cohorts from two basins in southwestern (SW; high arsenic area) and northeastern (NE; low arsenic area) Taiwan (n=297 and 2738, respectively), the arsenic exposure in well water was estimated using HPLC ICP-MS. Fungal infections were defined via clinical and mycological assessments (PCR of fungal 18S rRNA) of nail samples. Individuals in SW cohort with cumulative arsenic exposure >10,000MUg/L*years had a higher risk of developing fungal infections (OR=1.57, 95% CI=1.08-1.92) after adjusting for diabetes and occupation. In NE cohort, female sex, alcohol consumption, and chronic kidney diseases were associated with toenail infections. In contrast, fingernail infections (OR=1.33, 95% CI=1.05-1.68) were highly associated with arsenic exposure in a dose-dependent manner. We are the first to report palmar and plantar hyperkeratosis upon low arsenic exposure in 3.9% and 6.7% individuals, respectively. This is the first large-scale study showing arsenic exposure is associated with fungal infections in a dose-dependent manner. PMID- 27693977 TI - Differential fMRI BOLD responses in amygdala in intermittent explosive disorder as a function of past Alcohol Use Disorder. AB - BACKGROUND: Individuals with intermittent explosive disorder (IED) were previously found to exhibit amygdala (AMYG) hyperactivation to anger faces during functional magnetic resonance imaging (fMRI). However, acute alcohol consumption, and/or life history of alcoholism, may blunt amygdala responses to negative emotional stimuli. Thus, we examined the influence of a past history of DSM-5 Alcohol Use Disorder (AUD) on the fMRI BOLD AMYG response to anger faces in IED. METHOD: Forty-two IED participants, 18 with a past history of AUD (IED+AUD) and 24 without Past AUD (IED), and 32 healthy control (HC) participants, underwent fMRI scanning while viewing blocks of angry, fearful, and happy faces. RESULTS: Compared to HC and IED+AUD participants, IED subjects exhibited greater AMYG responses to angry, but not to fear or happy, faces in the left AMYG. There were no group differences in responses to anger, fear, or happy, faces in the OFC. CONCLUSION: These findings suggest the possibility of a longstanding effect of AUD on AMYG response in IED to anger-related stimuli and highlight the possibility that history of AUD should be considered as an important factor in the interpretation of fMRI studies involving the AMYG response to negative emotional stimuli. PMID- 27693979 TI - Polymorphisms in PDLIM5 gene are associated with alcohol dependence, type 2 diabetes, and hypertension. AB - The PDZ and LIM domain 5 (PDLIM5) gene may play a role in alcohol dependence (AD), bipolar disorder, and major depressive disorder; however, no study has identified shared genetic variants within PDLIM5 gene among AD, type 2 diabetes (T2D), and hypertension. This study investigated the association of 72 single nucleotide polymorphism (SNPs) with AD (1066 AD cases and 1278 controls) in the Study of Addiction - Genetics and Environment (SAGE) sample and 47 SNPs with T2D (878 cases and 2686 non-diabetic) and hypertension (825 cases and 2739 non hypertensive) in the Marshfield sample. Multiple logistic regression models in PLINK software were used to examine the associations of genetic variants with AD, T2D, and hypertension and SNP x alcohol consumption interactions for T2D and hypertension. Twenty-five SNPs were associated with AD in the SAGE sample (p < 0.05); rs1048627 showed the strongest association with AD (p = 5.53 * 10-4). Of the 25 SNPs, 5 SNPs showed associations with both AD in the SAGE sample and T2D in the Marshfield sample (top SNP rs11097432 with p = 0.00107 for T2D and p = 0.0483 for AD) while 6 SNPs showed associations with both AD in the SAGE sample and hypertension in the Marshfield sample (top SNP rs12500426 with p = 0.0119 for hypertension and p = 1.51 * 10-3 for AD). SNP (rs6532496) showed significant interaction with alcohol consumption for hypertension. Our results showed that several genetic variants in PDLIM5 gene influence AD, T2D and hypertension. These findings offer the potential for new insights into the pathogenesis of AD, T2D, and hypertension. PMID- 27693980 TI - Prospective prediction of first lifetime suicide attempts in a multi-site study of substance users. AB - Although considerable empirical work has been devoted to identifying risk factors for suicide attempts, most longitudinal research has studied recurrent attempts rather than first lifetime attempts. The present study sought to examine prospective predictors of first lifetime suicide attempts among adults receiving treatment for substance use. Data were drawn from the National Treatment Improvement Evaluation Study, a study of addiction treatment programs. Data were collected at treatment intake, treatment exit, and one year post-treatment. Patients (n = 3518) with no lifetime history of suicide attempts at treatment intake were followed at treatment exit and one year post-treatment, when they reported on the occurrence of suicide attempts since the prior assessment. Prospective suicidal behavior was assessed using logistic regression in relation to sociodemographic variables, health-related work impairment, history of psychiatric treatment utilization, history of suicidal ideation, history of depressive symptoms, substance use, and childhood abuse, assessed at intake. Health-related work impairment, history of suicidal ideation, and childhood physical abuse significantly predicted first lifetime attempts in a multivariate analysis. Suicidal ideation, health-related functional impairments, and childhood physical abuse may be particularly important in assessing risk for first lifetime suicide attempts. Findings suggest that future clinical work and research would benefit from considering these factors when identifying individuals at heightened risk of making a first suicide attempt. PMID- 27693981 TI - Anxious distress predicts subsequent treatment outcome and side effects in depressed patients starting antidepressant treatment. AB - Evidence has shown that the DSM-5 anxious distress specifier captures a clinically valid construct that predicts a worse clinical course. Although of importance for treatment planning and monitoring, however, the specifier's ability to predict treatment outcome is unknown. This is the first study to examine the ability of the DSM-5 anxious distress specifier to predict treatment response and side effects in depressed patients who recently initiated antidepressant treatment. Patients were from the Netherlands Study of Depression and Anxiety, an ongoing longitudinal cohort study. Baseline, 1-year and 2-year follow-up data were used from 149 patients (18-65 years) with current Major Depressive Disorder (MDD) who recently started adequately dosed antidepressant medication. Five self-report items were used to construct the DSM-5 anxious distress specifier. Treatment outcomes were depression severity after 1 year and 2 years, remission of MDD after 2 years and antidepressant side effects during treatment. For comparison, analyses were repeated for comorbid DSM-IV-based anxiety disorders as a predictor. In depressed patients who received antidepressant treatment, the anxious distress specifier (prevalence = 59.1%) significantly predicted higher severity (1 year: B = 1.94, P = 0.001; 2 years: B = 1.63, P = 0.001), lower remission rates (OR = 0.44, P = 0.0496) and greater frequency of side effects (>=4 vs. 0: OR = 2.74, P = 0.061). In contrast, the presence of comorbid anxiety disorders did not predict these treatment outcomes. The anxious distress specifier significantly predicts poorer treatment outcomes as shown by higher depression severity, lower remission rates, and greater frequency of antidepressant side effects in patients with MDD on adequate antidepressant treatment. Therefore, this simple 5-item specifier is of potential great clinical usefulness for treatment planning and monitoring in depressed patients. PMID- 27693982 TI - Prenatal betamethasone exposure and psychopathology risk in extremely low birth weight survivors in the third and fourth decades of life. AB - BACKGROUND: Mortality rates among extremely low birthweight (ELBW) infants have declined since the advent of antenatal glucocorticoid use. However, the long term neuropsychiatric effects of exposure are not well understood. We utilized the world's oldest longitudinally followed cohort of ELBW survivors to compare psychopathology over two decades in adulthood in those exposed to prenatal betamethasone and those who were not. METHODS: ELBW survivors (n=179) and matched normal birth weight (NBW) controls (n=145) completed the Young Adult Self-Report questionnaire at 22-26 and 29-36 years, and the Beck Depression and Anxiety Inventories at 29-36 years. Symptom levels and rates of clinically significant psychiatric problems were compared in ELBW survivors whose mothers were administered steroids during pregnancy (ELBW-S n=63), ELBW participants who were not (ELBW-NS, n=79), and NBW controls. RESULTS: At 22-26, ELBW-S had higher levels of anxiety, depressive, and avoidant personality symptoms, and a 3 to 5 fold increase in the odds of clinically significant levels of these problems compared to NBW controls, whereas ELBW-NS did not. These associations were maintained at 29-36, when ELBW-S participants exhibited a 3 to 10-fold increase in the odds of clinically significant anxiety and avoidant personality problems compared to NBW controls. At both time points, the odds of clinically significant anxiety problems were more than 3 times higher among ELBW-S than in ELBW-NS. CONCLUSION: ELBW adults exposed to prenatal betamethasone manifest higher levels of anxiety and depression than those who were not, and may represent a group of preterm survivors at particularly high psychiatric risk. PMID- 27693978 TI - Acupuncture treatment modulates the corticostriatal reward circuitry in major depressive disorder. AB - Major depressive disorder (MDD) is a common disorder with a high prevalence and significant social and economic impacts. Nevertheless, the treatment of MDD is far from satisfactory. Acupuncture treatment has emerged as a promising method for treating MDD. However, the neural mechanism by which acupuncture reduces depressive symptoms is not fully understood. Studies have shown that the corticostriatal reward circuitry is associated with the pathophysiology of MDD; thus, we investigated the corticostriatal resting-state functional connectivity (rsFC) before and after real and sham acupuncture treatments combined with the antidepressant fluoxetine. Forty-six female major depressive patients were assigned to either verum acupuncture plus fluoxetine (n = 22) or sham acupuncture plus fluoxetine (n = 24) treatment for 8 weeks, and resting state functional magnetic resonance imaging (fMRI) data were collected before the first and after the last treatment sessions. The results showed that compared with sham acupuncture, the verum acupuncture group showed: (1) significantly increased rsFC between inferior ventral striatum and medial prefrontal cortex, ventral rostral putamen and amygdala/parahippocampus, as well as dorsal caudate and middle temporal gyrus; (2) significantly decreased rsFC between right ventral rostral putamen and right dorsolateral prefrontal cortex, and right dorsal caudate and bilateral cerebellar tonsil. The increased rsFC between the inferior ventral striatum and medial prefrontal cortex, ventral rostral putamen and amygdala/parahippocampus were significantly positively associated with decreased clinical scores (Montgomery-Asberg Depression Rating Scale and Self-Rating Depression Scale scores) at the end of the eight-week treatment. Our findings suggest that acupuncture may achieve treatment effects by modulating the corticostriatal reward/motivation circuitry in MDD patients. PMID- 27693983 TI - Parenting and childhood atopic dermatitis: A cross-sectional study of relationships between parenting behaviour, skin care management, and disease severity in young children. AB - BACKGROUND: The development of child behaviour and parenting difficulties is understood to undermine treatment outcomes for children with atopic dermatitis. Past research has reported on correlates of child behaviour difficulties. However, few research studies have sought to examine parenting confidence and practices in this clinical group. OBJECTIVES: To examine relationships between child, parent, and family variables, parent-reported and directly-observed child and parent behaviour, parents' self-efficacy with managing difficult child behaviour, self-reported parenting strategies, and disease severity. DESIGN: Cross-sectional study design. PARTICIPANTS: Parent-child dyads (N=64) were recruited from the dermatology clinic of a paediatric tertiary referral hospital in Brisbane, Australia. Children had a diagnosis of atopic dermatitis of >=3months and no other chronic health conditions except asthma, allergic rhinitis, or allergy. METHODS: Parents completed self-report measures assessing child behaviour; parent depression, anxiety, and stress; parenting conflict and relationship satisfaction; self-efficacy with managing difficult child behaviour, and use of ineffective parenting strategies; and self-efficacy for managing atopic dermatitis, and performance of atopic dermatitis management tasks. The Scoring Atopic Dermatitis index was used to assess disease severity. Routine at home treatment sessions were coded for parent and child behaviour. RESULTS: Pearson's and Spearman's correlations identified relationships (p<0.05) between self-efficacy with managing difficult child behaviour and child behaviour problems, parent depression and stress, parenting conflict and relationship satisfaction, and household income. There were also relationships between each of these variables and use of ineffective parenting strategies. Greater use of ineffective parenting strategies was associated with more severe atopic dermatitis. Using multiple linear regressions, child behaviour and household income explained unique variance in self-efficacy for managing difficult child behaviour; household income alone explained unique variance in use of ineffective parenting strategies. Self-efficacy for managing difficult child behaviour and self-efficacy for managing atopic dermatitis were positively correlated (rho=0.48, p<0.001), and more successful self-reported performance of atopic dermatitis management tasks correlated with less permissive (r=0.35, p=0.005) and less authoritarian (r=0.41, p=0.001) parenting. Directly observed aversive child behaviour was associated with more severe atopic dermatitis, parent stress, and parent-reported child behaviour problems. CONCLUSION: This study revealed relationships between parents' self-efficacy and parenting practices across the domains of child behaviour management and atopic dermatitis management. Parents of children with more severe atopic dermatitis may have difficulty responding to child behaviour difficulties appropriately, potentially impacting on illness management. Incorporating parent and parenting support within treatment plans may improve not only child and family wellbeing, but also treatment outcomes. PMID- 27693984 TI - Implementation of an established algorithm and modifications for the identification of epilepsy patients in the veterans health administration. AB - Identification of epilepsy patients from administrative data in large managed healthcare organizations is a challenging task. The objectives of this report are to describe the implementation of an established algorithm and different modifications for the estimation of epilepsy prevalence in the Veterans Health Administration (VHA). For the prevalence estimation during a given time period patients prescribed anti-epileptic drugs and having seizure diagnoses on clinical encounters were identified. In contrast to the established algorithm, which required inclusion of diagnoses data from the time period of interest only, variants were tested by considering diagnoses data beyond prevalence period for improving sensitivity. One variant excluded data from diagnostic EEG and LTM clinics to improve specificity. Another modification also required documentation of seizures on the problem list (electronic list of patients' established diagnoses). Of the variants tested, the one excluding information from diagnostic clinics and extending time beyond base period of interest for clinical encounters was determined to be superior. It can be inferred that the number of patients receiving care for epilepsy in the VHA ranges between 74,000 and 87,000. In the wake of the recent implementation of ICD-10 codes in the VHA, minor tweaks are needed for future prevalence estimation due to significant efforts presented. This review is not only beneficial for researchers interested in VHA related data but can also be helpful for managed healthcare organizations involved in epilepsy care aiming at accurate identification of patients from large administrative databases. PMID- 27693985 TI - Accuracy of MEG in localizing irritative zone and seizure onset zone: Quantitative comparison between MEG and intracranial EEG. AB - BACKGROUND: We conducted the study to examine accuracy of the magnetoencephalography (MEG) spike source localization in presurgical evaluation of patients with medically refractory focal epilepsy. METHODS: Ten consecutive patients with refractory focal epilepsy who were candidates for two-stage surgery with long-term intracranial electroencephalography (ICEEG) monitoring were enrolled. Interictal MEG recordings with simultaneous scalp EEG were obtained within 7days before the ICEEG electrode implantation. The location of each MEG spike source was quantitatively compared with ICEEG spike foci (focal area of interictal spikes) and ICEEG ictal foci (earliest cortical origin of seizures). Gyral-width concordance and sublobar concordance were also determined for all MEG spike sources. Gyral-width concordance was defined by distance of 15mm or less between MEG spike sources and ICEEG spike foci or ICEEG ictal foci. RESULTS: Visual analyses of the MEG traces of all 10 patients revealed 292 spikes (29.2+/ 24.0 per patient). Spike yield of the MEG was similar to the simultaneously recorded scalp EEG. MEG spike sources were closely located with ICEEG spike foci (distance: 9.3+/-10.8mm). Clustered MEG spike sources were even closer to ICEEG spike foci (distance: 7.3+/-6.4mm). MEG spike sources, even clustered ones, were less concordant with ICEEG ictal foci and had significant longer distance from ICEEG ictal foci (distance: 21.5+/-15.6mm for all sources, 19.7+/-13.7mm for clustered sources). Gyral-width concordance rate and sublobar concordance rate were also higher with ICEEG interictal spike foci than with ICEEG ictal foci. On the other hand, 53.4% of interictal spike foci from ICEEG were not detected by interictal MEG recordings. CONCLUSIONS: MEG spike sources, especially clustered ones, from interictal recording could localize the irritative zone of ICEEG with a high accuracy. However, MEG spike sources have relatively poor correlation with seizure onset zone and lower sensitivity in identifying all irritative zones of ICEEG. This limitation should be considered in the interpretation of MEG results. PMID- 27693987 TI - Metabolic analysis of two contrasting wild barley genotypes grown hydroponically reveals adaptive strategies in response to low nitrogen stress. AB - Nitrogen (N) is an essential macronutrient for plants. The increasingly severe environmental problems caused by N fertilizer application urge alleviation of N fertilizer dependence in crop production. In previous studies, we identified the Tibetan wild barley accessions with high tolerance to low nitrogen (LN). In this study, metabolic analysis was done on two wild genotypes (XZ149, tolerant and XZ56, sensitive) to understand the mechanism of LN tolerance, using a hydroponic experiment. Leaf and root samples were taken at seven time points within 18 d after LN treatment, respectively. XZ149 was much less affected by low N stress than XZ56 in plant biomass. A total of 51 differentially accumulated metabolites were identified between LN and normal N treated plants. LN stress induced tissue specific changes in carbon and nitrogen partitioning, and XZ149 had a pattern of energy-saving amino acids accumulation and carbon distribution in favor of root growth that contribute to its higher LN tolerance. Moreover, XZ149 is highly capable of producing energy and maintaining the redox homeostasis under LN stress. The current results revealed the mechanisms underlying the wild barley in high LN tolerance and provided the valuable references for developing barley cultivars with LN tolerance. PMID- 27693986 TI - Magnetoencephalography spike sources interrelate the extensive epileptogenic zone of tuberous sclerosis complex. AB - OBJECTIVE: We hypothesized that the extensive epileptic network in patients with tuberous sclerosis complex (TSC) manifests as clustered and scattered distributions of magnetoencephalography spike sources (MEGSS). METHODS: We retrospectively analyzed pre-surgical MEG in 15 patients with TSC. We performed single moving dipole analysis to localize and classify clustered and scattered MEGSS. We compared the number of electrodes within the resected area (RA) and the proportions of clustered and scattered MEGSS within RA with the seizure outcome. RESULTS: The number of electrodes within RA ranged from 29 to 83 (mean=51). The MEGSS were distributed over multiple lobes (3-8; mean=5.9) and bilaterally in 14 patients. Clusters of MEGSS ranged from 1 to 4 (mean=1.4). The number of MEGSS ranged in total from 28 to 139 (mean=70); in the clusters, 10-128 (mean=49); and in the scatters, 0-45 (mean=21). Four patients achieved an Engel class I surgical outcome, four, a class II outcome; five, a class III outcome; and two, a class IV outcome. The proportion of MEGSS ranged in total from 0 to 92% (mean=57%) within RA; 0-100% (mean=67%) in the resection hemisphere; 0-100% (mean=63%) in the clusters; and 0-81% (mean=28%) in the scatters. Univariate ordinal logistic regression analyses showed that the proportion of scattered MEGSS within RA (p=0.049) significantly correlated with seizure outcomes. Multivariate analyses using three covariates (number of electrodes, proportions of clustered and scattered MEGSS within RA) showed that only the proportion of scattered MEGSS within RA significantly correlated with seizure outcomes (p=0.016). SIGNIFICANCE: MEG data showed a wide distribution of multilobar MEGSS in patients with TSC. The seizure outcome was not related to the clustered MEGSS within RA, since the grids were essentially planned to cover and resect the clustered MEGSS surrounding tubers. The maximal possible resection of scattered MEGSS correlated with improved seizure outcome in TSC. Some parts of the epileptogenic zone disrupted by multiple tubers did not have a sufficiently large area to produce clustered MEGSS. Although the wide distribution of scattered MEGSS is not interpreted as epileptogenic, they might be interrelated with clustered MEGSS to project a complex epilepsy network and be part of the extensive epileptogenic zones found in TSC. PMID- 27693988 TI - Gestational and lactational exposure to low-dose bisphenol A increases Th17 cells in mice offspring. AB - Increasing evidence demonstrates that perinatal exposure to Bisphenol A (BPA) can cause immune disorders throughout the life span. However, the biological basis for these immune disorders is poorly understood and the effects of exposure to BPA on Th17 development are unknown. The present study sought to characterize alterations of Th17 cells in childhood and adulthood following gestational and lactational exposure to environmentally relevant low-dose of BPA and the underlying mechanisms. Pregnant dams were exposed to BPA (10, 100 or 1000nM) via drinking water from gestational day (GD) 0 to postnatal day (PND) 21. At PNDs 21 and 42, offspring mice were anesthetized, blood was obtained for cytokine assay and spleens were collected for Th17 cell frequency and RORgammat mRNA expression analysis. Perinatal exposure to low-dose BPA resulted in a dose-dependent and gender-specific persistent rise in Th17 cells accompanied by an increase of RORgammat mRNA expression in the offsprings. The contents of major Th17 cell derived cytokines (IL-17 and IL-21) and those essential for Th17 cell differentiation (IL-6 and IL-23) were also increased compared to those in controls. These changes were more pronounced in female than in male offsprings. However, perinatal exposure to low-dose BPA had little effect on serum TGF-beta, another key regulator for Th17 cell development. Our results suggest that gestational and lactational exposure to a low-dose of BPA can affect Th17 cell development via an action on its transcription factor and the regulatory cytokines. These findings provide novel insight into sustained immune disorders by BPA exposure during development. PMID- 27693989 TI - A hip abduction exercise prior to prolonged standing increased movement while reducing cocontraction and low back pain perception in those initially reporting low back pain. AB - Persons who develop low back pain from prolonged standing exhibit increased muscle cocontraction, decreased movement and increased spine extension. However, it is unclear how these factors relate to pain development. The purpose of this study was to use hip abductor fatigue to manipulate muscle activity patterns and determine its effects on standing behaviours and pain development. Forty participants stood for two hours twice, once following a hip abductor fatigue exercise (fatigue), and once without exercise beforehand (control). Trunk and gluteal muscle activity were measured to determine cocontraction. Lumbo-pelvic angles and force plates were used to assess posture and movement strategies. Visual analog scales differentiated pain (PDs) and non-pain developers (NPDs). PDs reported less low back pain during the fatigue session, with females having earlier reductions of similar scale than males. The fatigue session reduced gluteal and trunk cocontraction and increased centre of pressure movement; male and female PDs had opposing spine posture compensations. Muscle fatigue prior to standing reduced cocontraction, increased movement during standing and reduced the low back pain developed by PDs; the timing of pain reductions depended on spine postures adopted during standing. PMID- 27693990 TI - Mcconnell's patellar taping does not alter knee and hip muscle activation differences during proprioceptive exercises: A randomized placebo-controlled trial in women with patellofemoral pain syndrome. AB - : The purpose of this study was to assess the effect of patellar taping on muscle activation of the knee and hip muscles in women with Patellofemoral Pain Syndrome during five proprioceptive exercises. Forty sedentary women with syndrome were randomly allocated in two groups: Patellar Taping (based in McConnell) and Placebo (vertical taping on patella without any stretching of lateral structures of the knee). Volunteers performed five proprioceptive exercises randomly: Swing apparatus, Mini-trampoline, Bosu balance ball, Anteroposterior sway on a rectangular board and Mediolateral sway on a rectangular board. All exercises were performed in one-leg stance position with injured knee at flexion of 30 degrees during 15s. Muscle activation was measured by surface electromyography across Vastus Medialis, Vastus Lateralis and Gluteus medius muscles. Maximal voluntary contraction was performed for both hip and knee muscles in order to normalize electromyography signal relative to maximum effort during the exercises. ANOVA results reported no significant interaction (P>0.05) and no significant differences (P>0.05) between groups and intervention effects in all exercise conditions. Significant differences (P<0.01) were only reported between muscles, where hip presented higher activity than knee muscles. Patellar taping is not better than placebo for changes in the muscular activity of both hip and knee muscles during proprioceptive exercises. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT02322515. PMID- 27693991 TI - Simplifying and expanding analytical capabilities for various classes of doping agents by means of direct urine injection high performance liquid chromatography high resolution/high accuracy mass spectrometry. AB - So far, in sports drug testing compounds of different classes are processed and measured using different screening procedures. The constantly increasing number of samples in doping analysis, as well as the large number of substances with doping related, pharmacological effects require the development of even more powerful assays than those already employed in sports drug testing, indispensably with reduced sample preparation procedures. The analysis of native urine samples after direct injection provides a promising analytical approach, which thereby possesses a broad applicability to many different compounds and their metabolites, without a time-consuming sample preparation. In this study, a novel multi-target approach based on liquid chromatography and high resolution/high accuracy mass spectrometry is presented to screen for more than 200 analytes of various classes of doping agents far below the required detection limits in sports drug testing. Here, classic groups of drugs as diuretics, stimulants, beta2-agonists, narcotics and anabolic androgenic steroids as well as various newer target compounds like hypoxia-inducible factor (HIF) stabilizers, selective androgen receptor modulators (SARMs), selective estrogen receptor modulators (SERMs), plasma volume expanders and other doping related compounds, listed in the 2016 WADA prohibited list were implemented. As a main achievement, growth hormone releasing peptides could be implemented, which chemically belong to the group of small peptides (<2kDa) and are commonly determined by laborious and time consuming stand-alone assays. The assay was fully validated for qualitative purposes considering the parameters specificity, robustness (rRT: <2%), intra- (CV: 1.7-18.4 %) and inter-day precision (CV: 2.3-18.3%) at three concentration levels, linearity (R2>0.99), limit of detection (0.1-25ng/mL; 3'OH-stanozolol glucuronide: 50pg/mL; dextran/HES: 10MUg/mL) and matrix effects. PMID- 27693993 TI - The C of CHADS: Historical perspective and clinical applications for anticoagulation in patients with non valvular atrial fibrillation and congestive heart failure. AB - The risk stratification of patients with coexisting non valvular atrial fibrillation and congestive heart failure, is often a clinical challenge, as the definitions of congestive heart failure in the popular CHADS2 and CHA2DS2VASc scoring systems, and amongst major clinical trials on Warfarin and Novel Oral Anticoagulants (NOAC) have heterogeneity. Available evidence reveals that any heart failure and/or left ventricular systolic dysfunction is associated with higher rates of stroke/systemic embolism and bleeding in patients with non valvular atrial fibrillation compared to patients without heart failure and normal left ventricular function. Most standard dose NOAC regimens have a better safety and efficacy profile over warfarin in most heart failure sub-group types with a few exceptions including patients with NYHA III/IV on Dabigatran 150mg BID from the RE-LY trial, who had higher major bleeding events, and patients with asymptomatic left ventricular dysfunction (ejection fraction <=40%) and heart failure with reduced ejection fraction on 20mg of Rivaroxaban in the ROCKET-AF trial, when compared to patients on Warfarin in the corresponding groups. With the gaining popularity and use of NOACs, understanding their safety profile in such situations is paramount. PMID- 27693992 TI - The redox mechanism for vascular barrier dysfunction associated with metabolic disorders: Glutathionylation of Rac1 in endothelial cells. AB - BACKGROUND: Oxidative stress is implicated in increased vascular permeability associated with metabolic disorders, but the underlying redox mechanism is poorly defined. S-glutathionylation, a stable adduct of glutathione with protein sulfhydryl, is a reversible oxidative modification of protein and is emerging as an important redox signaling paradigm in cardiovascular physiopathology. The present study determines the role of protein S-glutathionylation in metabolic stress-induced endothelial cell permeability. METHODS AND RESULTS: In endothelial cells isolated from patients with type-2 diabetes mellitus, protein S glutathionylation level was increased. This change was also observed in aortic endothelium in ApoE deficient (ApoE-/-) mice fed on Western diet. Metabolic stress-induced protein S-glutathionylation in human aortic endothelial cells (HAEC) was positively correlated with elevated endothelial cell permeability, as reflected by disassembly of cell-cell adherens junctions and cortical actin structures. These impairments were reversed by adenoviral overexpression of a specific de-glutathionylation enzyme, glutaredoxin-1 in cultured HAECs. Consistently, transgenic overexpression of human Glrx-1 in ApoE-/- mice fed the Western diet attenuated endothelial protein S-glutathionylation, actin cytoskeletal disorganization, and vascular permeability in the aorta. Mechanistically, glutathionylation and inactivation of Rac1, a small RhoGPase, were associated with endothelial hyperpermeability caused by metabolic stress. Glutathionylation of Rac1 on cysteine 81 and 157 located adjacent to guanine nucleotide binding site was required for the metabolic stress to inhibit Rac1 activity and promote endothelial hyperpermeability. CONCLUSIONS: Glutathionylation and inactivation of Rac1 in endothelial cells represent a novel redox mechanism of vascular barrier dysfunction associated with metabolic disorders. PMID- 27693994 TI - Effectiveness of hypolimnetic oxygenation for preventing accumulation of Fe and Mn in a drinking water reservoir. AB - The accumulation of Fe and Mn in seasonally stratified drinking water reservoirs adversely impacts water quality. To control issues with Fe and Mn at the source, some drinking water utilities have deployed hypolimnetic oxygenation systems to create well-oxygenated conditions in the water column that are favorable for the oxidation, and thus removal, of Fe and Mn. However, in addition to being controlled by dissolved oxygen (DO), Fe and Mn concentrations are also influenced by pH and metal-oxidizing microorganisms. We studied the response of Fe and Mn concentrations to hypolimnetic oxygenation in a shallow drinking water reservoir in Vinton, Virginia, USA by sequentially activating and deactivating an oxygenation system over two summers. We found that maintaining well-oxygenated conditions effectively prevented the accumulation of soluble Fe in the hypolimnion. However, while the rate of Mn oxidation increased under well oxygenated conditions, soluble Mn still accumulated in the slightly acidic to neutral (pH 5.6 to 7.5) hypolimnion. In parallel, we conducted laboratory incubation experiments, which showed that the presence of Mn-oxidizing microorganisms increased the rate of Mn oxidation in comparison with rates under oxic, abiotic conditions. Combined, our field and laboratory results demonstrate that increasing DO concentrations in the water column is important for stimulating the oxidation of Fe and Mn, but that the successful management of Mn is also tied to the activity of Mn-oxidizing organisms in the water column and favorable (neutral to alkaline) pH. PMID- 27693995 TI - Immobilization of Cd in river sediments by sodium alginate modified nanoscale zero-valent iron: Impact on enzyme activities and microbial community diversity. AB - This paper investigated how sodium alginate (SA)-modified nanoscale zero-valent iron (NZVI), play a constructive role in the remediation of cadmium (Cd) contaminated river sediments. The changes of the fraction of Cd, enzyme activities (urease, catalase, dehydrogenase) and bacterial community structures with the treatment by SNZVI were observed. The sequential extraction experiments demonstrated that most mobile fractions of Cd were transformed into residues (the maximum residual percentage of Cd increases from 15.49% to 57.28% after 30 days of incubation at 0.1 wt% SA), with the decrease of bioavailability of Cd. Exclusive of dehydrogenase, the activities of the other two enzymes tested were enhanced with the increase of incubation time, which indicated that dehydrogenase might be inhibited by ferric ions formed from SNZVI whereas no obvious inhibition was found for other enzymes. Polymerase chain reaction denaturing gradient gel electrophoresis (PCR-DGGE) analyses were used for the detection of microbial community changes, and the results showed that SNZVI and NZVI could increase bacterial taxa and improve bacterial abundance. All the experimental findings of this study provide new insights into the potential consequences of SNZVI treatments on the metal Cd immobilization in contaminated river sediments. PMID- 27693996 TI - Adverse childhood experiences, health, and employment: A study of men seeking job services. AB - The present study explored factors associated with barriers to current employment among 199 low-income, primarily Black American men seeking job services. The study took place in an urban setting located within the upper Midwest region of the U.S., where the problem of Black male joblessness is both longstanding and widespread. Recent research suggests that Black male joblessness regionally and nationally is attributable to myriad macro- and micro-level forces. While structural-level factors such as migration of available jobs, incarceration patterns, and racism have been relatively well-studied, less is known about individual-level predictors of Black male joblessness, which are inextricably linked to macro-level or structural barriers. This study therefore examined relations between adverse childhood experiences (ACEs), health-related factors, and employment-related problems. Participants faced both specific and cumulative childhood adversities at much higher rates than men from more economically advantaged contexts. In addition, the physical, behavioral, and mental health of the study participants were, according to self-report survey results, notably worse than that of the general population or alternative samples. Finally, results indicated that exposure to ACEs may have helped to undermine the men's ability to attain current employment and that drug problems along with depression symptoms helped explain the link between ACEs and employment barriers. Theoretical and practical implications of results are explored. PMID- 27693997 TI - Mental rotation and working memory in musicians' dystonia. AB - BACKGROUND: Mental rotation of body parts engages cortical-subcortical areas that are actually involved in the execution of a movement. Musicians' dystonia is a type of focal hand dystonia that is grouped together with writer's cramp under the rubric of "occupational dystonia", but it is unclear to which extent these two disorders share common pathophysiological mechanisms. Previous research has demonstrated patients with writer's cramp to have deficits in mental rotation of body parts. It is unknown whether patients with musicians' dystonia would display similar deficits, reinforcing the concept of shared pathophysiology. METHODS: Eight patients with musicians' dystonia and eight healthy musicians matched for age, gender and musical education, performed a number of tasks assessing mental rotation of body parts and objects as well as verbal and spatial working memories abilities. RESULTS: There were no differences between patients and healthy musicians as to accuracy and reaction times in any of the tasks. CONCLUSIONS: Patients with musicians' dystonia have intact abilities in mentally rotating body parts, suggesting that this disorder relies on a highly selective disruption of movement planning and execution that manifests only upon playing a specific instrument. We further demonstrated that mental rotation of body parts and objects engages, at least partially, different cognitive networks. PMID- 27693998 TI - Erratum to "Impaired executive functions in subjects with frequent nightmares as reflected by performance in different neuropsychological tasks" [Brain Cognit. 78 (2012) 274-283]. PMID- 27693999 TI - Predictive action tracking without motor experience in 8-month-old infants. AB - A popular idea in cognitive neuroscience is that to predict others' actions, observers need to map those actions onto their own motor repertoire. If this is true, infants with a relatively limited motor repertoire should be unable to predict actions with which they have no previous motor experience. We investigated this idea by presenting pre-walking infants with videos of upright and inverted stepping actions that were briefly occluded from view, followed by either a correct (time-coherent) or an incorrect (time-incoherent) continuation of the action (Experiment 1). Pre-walking infants looked significantly longer to the still frame after the incorrect compared to the correct continuations of the upright, but not the inverted stepping actions. This demonstrates that motor experience is not necessary for predictive tracking of action kinematics. In a follow-up study (Experiment 2), we investigated sensorimotor cortex activation as a neural indication of predictive action tracking in another group of pre-walking infants. Infants showed significantly more sensorimotor cortex activation during the occlusion of the upright stepping actions that the infants in Experiment 1 could predictively track, than during the occlusion of the inverted stepping actions that the infants in Experiment 1 could not predictively track. Taken together, these findings are inconsistent with the idea that motor experience is necessary for the predictive tracking of action kinematics, and suggest that infants may be able to use their extensive experience with observing others' actions to generate real-time action predictions. PMID- 27694001 TI - Relevance of carnosic acid to the treatment of several health disorders: Molecular targets and mechanisms. AB - Carnosic acid is a phenolic diterperne compound found in abundance in sage and rosemary, which are both widely used in traditional medicine. Research over the past decade indicates that carnosic acid has multiple bioactive properties including antioxidant, anti-inflammatory and anticancer activities among others. This review summarizes the current in vitro and in vivo data about the efficacy of carnosic acid in the prevention or treatment of various experimental health disorders. The analysis of the literature allows an insight into the participation of numerous signaling pathways modulated by carnosic acid, into its synergistic potential and, thus, into the divergence in cellular mechanisms of action of this molecule. PMID- 27694000 TI - Neuroprotective effects of quercetin on memory and anxiogenic-like behavior in diabetic rats: Role of ectonucleotidases and acetylcholinesterase activities. AB - The present study investigated the protective effect of quercetin (Querc) on memory, anxiety-like behavior and impairment of ectonucleotidases and acetylcholinesterase (AChE) activities in brain of streptozotocin-induced diabetic rats (STZ-diabetes). The type 1 diabetes mellitus was induced by an intraperitoneal injection of 70mg/kg of streptozotocin (STZ), diluted in 0.1M sodium-citrate buffer (pH 4.5). Querc was dissolved in 25% ethanol and administered by gavage at the doses of 5, 25 and 50mg/kg once a day during 40days. The animals were distributed in eight groups of ten animals as follows: vehicle, Querc 5mg/kg, Querc 25mg/kg, Querc 50mg/kg, diabetes, diabetes plus Querc 5mg/kg, diabetes plus Querc 25mg/kg and diabetes plus Querc 50mg/kg. Querc was able to prevent the impairment of memory and the anxiogenic-like behavior induced by STZ-diabetes. In addition, Querc prevents the decrease in the NTPDase and increase in the adenosine deaminase (ADA) activities in SN from cerebral cortex of STZ-diabetes. STZ-diabetes increased the AChE activity in SN from cerebral cortex and hippocampus. Querc 50mg/kg was more effective to prevent the increase in AChE activity in the brain of STZ-diabetes. Querc also prevented an increase in the malondialdehyde levels in all the brain structures. In conclusion, the present findings showed that Querc could prevent the impairment of the enzymes that regulate the purinergic and cholinergic extracellular signaling and improve the memory and anxiety-like behavior induced by STZ diabetes. PMID- 27694003 TI - Differential role of microRNAs in prognosis, diagnosis, and therapy of ovarian cancer. AB - Ovarian cancer (OC) is the most lethal of malignant gynecological cancers, and has a very poor prognosis, frequently, attributable to late diagnosis and responsiveness to chemotherapy. In spite of the technological and medical approaches over the past four decades, involving the progression of several biological markers (mRNA and proteins biomarkers), the mortality rate of OC remains a challenge due to its late diagnosis, which is expressly ascribed to low specificities and sensitivities. Consequently, there is a crucial need for novel diagnostic and prognostic markers that can advance and initiate more individualized treatment, finally increasing survival of the patients. MiRNAs are non-coding RNAs that control target genes post transcriptionally. They are included in tumorigenesis, apoptosis, proliferation, invasion, metastasis, and chemoresistance. Several studies have within the last decade demonstrated that miRNAs are dysregulated in OC and have possibilities as diagnostic and prognostic biomarkers for OC. Additionally; recent studies have also focused on miRNAs as predictors of chemotherapy sensitivities and their potential as therapeutic targets. In this review, we discuss the current data involving the accumulating evidence of the altered expression of miRNAs in OC, their role in diagnosis, prognosis, and forecast of response to therapy. Given the heterogeneity of this disease, it is likely that advances in long-term survival might be also attained by translating the recent insights of miRNAs participation in OC into new targeted therapies that will have a crucial effect on the management of ovarian cancer. PMID- 27694002 TI - Down-regulation of microRNA-338-3p promoted angiogenesis in hepatocellular carcinoma. AB - miRNAs are involved in substantial biological passways, including tumorigenesis, cancer development and progression. Angiogenesis plays a vital role in the progression of hepatocellular carcinoma (HCC), and VEGF is closely associated with the angiogenesis. However, the molecular mechanism of miRNAs in regulation tumorigenesis of HCC remains to be investigated. In the present research, we confirmed that miR-338-3p was suppressed both in HCC tissues and HCC cell lines. Then the tube formation, transwell and Chorioallantoic membrane (CAM) assay were carried out, such indicated that down-regulation of miR-338-3p can sharply increased, while up-regulation drastically suppressed angiogenesis of HCC cells in vitro. Moreover, MACC1 is predicted to be a target of miR-338-3p and we checked the prediction through luciferase assay. And then, our research showed that negative correlation existed between miR-338-3p and MACC1, beta-catenin and VEGF that has been reported participated in cancer behavior in HCC cell lines. Subsequently, our assays illustrated that suppression miR-338-3p can up-regulate MACC1, beta-catenin and VEGF expression of HCC cells. In conclusion, our research discovered that miR-338-3p can contribute to HCC angiogenesis by targeting MACC1, beta-catenin and VEGF. PMID- 27694004 TI - Odontogenic ameloblast-associated protein (ODAM) inhibits human colorectal cancer growth by promoting PTEN elevation and inactivating PI3K/AKT signaling. AB - Odontogenic ameloblast-associated protein (ODAM), an acidic matricellular protein, has been implicated in several epithelial neoplasms. However, its biological functions and molecular mechanisms in cancer progression, particular colorectal carcinoma (CRC), remain unknown. Here we demonstrated that ODAM was significantly down-regulated in CRC tissues compared with their normal counterparts. Then, we established that ODAM expression level was closely correlated with CRC development and patient prognosis. The abnormal expression of ODAM dramatically affected CRC cell growth in vitro and in vivo. We further revealed that the inhibitory effects of ODAM on CRC cell growth were associated with PTEN elevation and PI3K/AKT signaling inactivation. Furthermore, we determined that silencing of PTEN expression yielded recovery of AKT activity in ODAM-expressing CRC cells. Our study suggests matricellular protein ODAM may serve as a novel prognostic marker and act as a CRC growth suppressor. PMID- 27694005 TI - Enhanced miR-9 promotes laryngocarcinoma cell survival via down-regulating PTEN. AB - MicroRNAs (miRNAs) play important roles in gene regulation during laryngocarcinoma. MiR-9 is a potential oncomiR, but its function in laryngocarcinoma is not known. The aim of this study is to investigate the roles of miR-9 in laryngocarcinoma. We found miR-9 expression was higher in laryngocarcinoma tissues compared with their normal controls, so did the laryngocarcinoma cells. Cellular function of miR-9 indicated that miR-9 restoration in laryngocarcinoma cells could promote cell proliferation and metastasis. Phosphatase and tensin homolog (PTEN) was predicted as a target gene of miR-9 and verified using luciferase reporter assay. PTEN expression was down regulated in the laryngocarcinoma cells with miR-9 overexpression. We also found that miR-9 expression was negatively associated with PTEN expression in laryngocarcinoma tissues. PMID- 27694007 TI - Morin inhibits cell proliferation and fibronectin accumulation in rat glomerular mesangial cells cultured under high glucose condition. AB - Morin, is a natural bioflavonoid isolated from Chinese herbs of the Moraceae family, has been reported to possess antidiabetic activity. However, the role of morin on glomerular mesangial cells (MCs) proliferation and extracellular matrix (ECM) accumulation in diabetic condition is still unclear. Therefore, in this study, we investigated the role of morin on cell proliferation and ECM accumulation in rat glomerular MCs cultured under high glucose (HG) condition. Our results showed that morin inhibited HG-induced MC proliferation, arrested HG induced cell-cycle progression, reversed HG-inhibited expression of p21Waf1/Cip1 and p27Kip1. It also inhibited HG-induced ECM expression, ROS generation and NOX4 expression in MCs. Furthermore, morin suppressed HG-induced phosphorylation of p38 MAPK and JNK1/2 in MCs. These data suggest that morin inhibits HG-induced MC proliferation and ECM expression through suppressing the activation of p38 MAPK and JNK signaling pathways. Thus, morin may be useful for the prevention or treatment of diabetic nephropathy. PMID- 27694006 TI - Cytotoxic and antioxidative potentials of ethanolic extract of Eugenia uniflora L. (Myrtaceae) leaves on human blood cells. AB - Eugenia uniflora is used in the Brazilian folk medicine to treat intestinal disorders and hypertension. However, scanty information exist on its potential toxicity to human, and little is known on its antioxidant activity in biological system. Hence, we investigated for the first time the potential toxic effects of ethanolic extract (EtOH) of E. uniflora (EEEU) in human leukocytes and erythrocytes, as well as its influence on membrane erythrocytes osmotic fragility. In addition, EEEU was chemically characterized and its antioxidant capacity was evaluated. We found that EEEU (1-480MUg/mL) caused neither cytotoxicity nor DNA damage evaluated by Trypan blue and Comet assay, respectively. EEEU (1-480MUg/mL) did not have any effect on membrane erythrocytes fragility. In addition, EEEU inhibited Fe2+-induced lipid peroxidation in rat brain and liver homogenates, and scavenged the DPPH radical. EEEU presented some polyphenolic compounds with high content such as quercetin, quercitrin, isoquercitrin, luteolin and ellagic acid, which may be at least in part responsible for its beneficial effects. Our results suggest that consumption of EEEU at relatively higher concentrations may not result in toxicity. However, further in vitro and in vivo studies should be conducted to ascertain its safety. PMID- 27694008 TI - New potential phytotherapeutics obtained from white mulberry (Morus alba L.) leaves. AB - The present work demonstrates the profound and unique phyto-pharmacological and nutritional profile of white mulberry (Morus alba L.) leaves which containing considerable amounts of easy digestive proteins, carbohydrates, micro- and macronutrients, polyphenols, free amino acids, organic acids. The wide range of significant biopharmaceutical activities of the aqueous and polar organic solvents extracts from mulberry leaves - including antidiabetic, antibacterial, anticancer, cardiovascular, hypolipidemic, antioxidant, antiatherogenic, and anti inflammatory - have been critically discussed. The main objective was to demonstrate the results of recently published study on the components of white mulberry leaves exhibiting their biological activity in the various pathological and health human ailments. In addition, we intend to drawn the attention of researchers and public health workers for the extended exploration of this deciduous plant leaves as the source of potential indigenous nutraceuticals and functional food products to enable development of alternative prevention and treatment protocols offered in therapy of the common non-communicable diseases and malignances. PMID- 27694010 TI - Dualistic temperature sensing in Er3+/Yb3+ doped CaMoO4 upconversion phosphor. AB - Temperature sensing performance of Er3+/Yb3+ doped CaMoO4 phosphor prepared via polyol method is reported herein. The X-ray diffraction, Fourier transform infrared spectroscopy and field emission scanning electron microscopy are done to confirm the phase, structure and purity of the synthesized phosphor. The infrared to green upconversion emission is investigated using 980nm diode laser excitation along with its dependence on input pump power and external temperature. The temperature dependent fluorescence intensity ratio of two upconversion emission bands assigned to 2H11/2->4I15/2 (530nm) and 4S3/2->4I15/2 (552nm) transitions has shown two distinct slopes in the studied temperature range - 300 to 760K and therefore, dual nature of temperature sensitivity is observed in this phosphor. This phenomenon in rare earth doped materials is either scarcely reported or overlooked. The material has shown higher sensitivity in the high temperature region (535K=60) and younger than sixty (<60) years (yrs). METHODS: We retrospectively analyzed 120 patients (48 women) with SE admitted to the Neurological Intensive Care Unit (NICU), Department of Neurology, Paracelsus Medical University Salzburg, Austria between 1/2011 and 01/2013. KEY FINDINGS: Median age was 69 years (range 14-90) (63% >=60yrs). Generalized tonic clonic SE was the most common SE type, whereas non convulsive SE with and without coma tended to occur more frequently in the elderly (33% >=60 yrs. vs. 20%<60 yrs, Chi2=3.511, p=0.061). Preexisting history of epilepsy was more common in the younger age group (64% vs 41% p=0.014). An acute symptomatic cause of SE was identified in 25% (31/120), with cerebrovascular diseases being more frequent in the elderly (47% vs. 11%; p<0.01). Duration of SE did not differ between the age groups (p=0.63). Mortality was higher in elderly patients (31% vs. 7%, p=0.028, Chi Square=5.18) and moderate disability in younger patients (42% vs 17%; p=0.005, Chi Square=7.83). After Bonferroni correction only the higher rate of cerebrovascular etiologies in the elderly was statistically significant. SIGNIFICANCE: In the elder population, SE occurs more often in patients without preexisting epilepsy and is most frequently caused by cerebrovascular diseases. NCSE tends to be more frequent in the elderly and diagnosis is complicated by subtle clinical presentation. Even though comorbidities represent treatment limitations, in our sample no differences in choice of AED as well as dosage were observed between the age groups, reflecting a trend toward AEDs with more favorable adverse event profile in all patients. SE in older patients is associated with poorer outcome and higher mortality. PMID- 27694015 TI - Local deformation behavior of surface porous polyether-ether-ketone. AB - Surface porous polyether-ether-ketone has the ability to maintain the tensile monotonic and cyclic strength necessary for many load bearing orthopedic applications while providing a surface that facilitates bone ingrowth; however, the relevant deformation behavior of the pore architecture in response to various loading conditions is not yet fully characterized or understood. The focus of this study was to examine the compressive and wear behavior of the surface porous architecture using micro Computed Tomography (micro CT). Pore architectures of various depths (~0.5-2.5mm) and pore sizes (212-508um) were manufactured using a melt extrusion and porogen leaching process. Compression testing revealed that the pore architecture deforms in the typical three staged linear elastic, plastic, and densification stages characteristic of porous materials. The experimental moduli and yield strengths decreased as the porosity increased but there was no difference in properties between pore sizes. The porous architecture maintained a high degree of porosity available for bone-ingrowth at all strains. Surface porous samples showed no increase in wear rate compared to injection molded samples, with slight pore densification accompanying wear. PMID- 27694016 TI - Reading ability reflects individual differences in auditory brainstem function, even into adulthood. AB - Research with developmental populations suggests that the maturational state of auditory brainstem encoding is linked to reading ability. Specifically, children with poor reading skills resemble biologically younger children with respect to their auditory brainstem responses (ABRs) to speech stimulation. Because ABR development continues into adolescence, it is possible that the link between ABRs and reading ability changes or resolves as the brainstem matures. To examine these possibilities, ABRs were recorded at varying presentation rates in adults with diverse, yet unimpaired reading levels. We found that reading ability in adulthood related to ABR Wave V latency, with more juvenile response morphology linked to less proficient reading ability, as has been observed for children. These data add to the evidence indicating that auditory brainstem responses serve as an index of the sound-based skills that underlie reading, even into adulthood. PMID- 27694018 TI - Substance flow analysis and environmental releases of PBDEs in life cycle of automobiles. AB - Polybrominated diphenyl ethers (PBDEs), a class of brominated flame retardants, have been widely used in many applications in industry such as automobiles, textiles, and electronics. This study focused on a quantitative substance flow analysis (SFA) of PBDEs in automobiles in order to identify their flow by life cycle and treatment pathways of PBDEs-containing materials in end-of-life vehicles (ELVs) in Korea. In addition, this study has estimated environmental releases of PBDEs in automobiles by life cycle in Korea. During this study, PBDEs were analyzed for the samples collected from several ELVs treatment facilities using X-ray fluorescence and gas chromatography/mass spectrometry (GC/MS) methods. The system boundary for SFA of PBDEs ranged from manufacturing/trade to disposal stage of automobiles by life cycle. Based on the result of the SFA, it was found that the amount of PBDEs in automobiles were the highest in use stage (7748ton/year), followed by production stage (1743ton/year) in 2014. In disposal stage, automobile shredded residues (ASR) and seat fabrics were the main components with relatively high levels of PBDEs in ELVs. The major treatment methods of such components included incineration (84%), energy recovery (9%), and landfilling (6%). This research indicates that PBDEs were emitted the highest amount from interior components during the use stage of automobiles, followed by recycling processes such as dismantling and shredding. This study suggests that PBDEs in ASR and seat fabrics should be properly managed to prevent the widespread dispersion in the environment. PMID- 27694019 TI - Promotion of enamel caries remineralization by an amelogenin-derived peptide in a rat model. AB - OBJECTIVE: An amelogenin-derived peptide has been shown to promote remineralization of demineralized enamel in an in vitro model of initial caries induced by pH cycling. The present study examines whether the peptide exerts similar effects within the complex oral environment in vivo. DESIGN: Specific pathogen-free Sprague-Dawley rats (n=36) were infected with Streptococcus mutans, given ad libitum access to Diet 2000 and drinking water supplemented with sucrose (10%, w/v), and then randomly divided into three groups treated with 25MUM peptide solution, 1g/L NaF or deionized water. Molar teeth were swabbed twice daily with the respective solutions for 24days. Then animals were killed, their jaws were removed and caries lesions were analyzed using the quantitative light induced fluorescence-digital (QLF-D) technique to measure changes in mineral content. To verify QLF-D results, caries were scored for lesion depth and size using the Keyes method, and analyzed using polarized light microscopy (PLM). RESULTS: Mineral gain was significantly higher in teeth treated with peptide or NaF than in teeth treated with water (p<0.05), based on the QLF-D results (DeltaF and DeltaQ). Incidence of smooth-surface and sulcal caries based on Keyes scores was similar in rats treated with peptide or NaF, and significantly lower in these groups than in rats treated with water (p<0.05). Lesions on teeth treated with peptide or NaF were shallower, based on PLM. No significant differences were observed between molar enamel caries treated with peptide or NaF. CONCLUSIONS: This amelogenin-derived peptide can promote remineralization in a rat caries model, indicating strong potential for clinical use. PMID- 27694017 TI - Subjective experience of inner speech in aphasia: Preliminary behavioral relationships and neural correlates. AB - Many individuals with aphasia describe anomia with comments like "I know it but I can't say it." The exact meaning of such phrases is unclear. We hypothesize that at least two discrete experiences exist: the sense of (1) knowing a concept, but failing to find the right word, and (2) saying the correct word internally but not aloud (successful inner speech, sIS). We propose that sIS reflects successful lexical access; subsequent overt anomia indicates post-lexical output deficits. In this pilot study, we probed the subjective experience of anomia in 37 persons with aphasia. Self-reported sIS related to aphasia severity and phonological output deficits. In multivariate lesion-symptom mapping, sIS was associated with dorsal stream lesions, particularly in ventral sensorimotor cortex. These preliminary results suggest that people with aphasia can often provide meaningful insights about their experience of anomia and that reports of sIS relate to specific lesion locations and language deficits. PMID- 27694020 TI - 4-Hydroxyphenylacetic acid oxidation in sulfate and real olive oil mill wastewater by electrochemical advanced processes with a boron-doped diamond anode. AB - The degradation of 4-hydroxyphenylacetic acid, a ubiquitous component of olive oil mill wastewater (OOMW), has been studied by anodic oxidation with electrogenerated H2O2 (AO-H2O2), electro-Fenton (EF) and photoelectro-Fenton (PEF). Experiments were performed in either a 0.050M Na2SO4 solution or a real OOMW at pH 3.0, using a cell with a boron-doped diamond (BDD) anode and an air diffusion cathode for H2O2 generation. Hydroxyl radicals formed at the BDD surface from water oxidation in all processes and/or in the bulk from Fenton's reaction between added Fe2+ and generated H2O2 in EF and PEF were the main oxidants. In both matrices, the oxidation ability of the processes increased in the order AO-H2O2digestive system>head>tail>body wall, suggesting that DecaBDE was mainly uptaken through ingestion. Up to 31% of the 14C-DecaBDE in the earthworms was not extractable, revealing that the total concentration of accumulated 14C-DecaBDE was underestimated. The results also showed that the presence of DecaBDE-degrading bacteria did not significantly affect the fate of DecaBDE and its accumulation in earthworms. The study indicates that the conventional assessment of the bioaccumulation and ecological effects of DecaBDE, which is based only on extractable concentrations, may underestimate the risks. PMID- 27694024 TI - Toxicity assessment of carbon black waste: A by-product from oil refineries. AB - In Singapore, approximately 30t/day of carbon-based solid waste are produced from petrochemical processes. This carbon black waste has been shown to possess physical properties that are characteristic of a good adsorbent such as high external surface area. Therefore, there is a growing interest to reutilize and process this carbon black waste into secondary materials such as adsorbents. However, the carbon black waste obtained from petrochemical industries may contain heavy metals that are hazardous to human health and the environment, hence restricting its full potential for re-utilization. Therefore, it is important to examine the possible toxicity effects and toxicity mechanism of carbon black waste on human health. In this study, inductively coupled plasma optical emission spectroscopy (ICP-OES) analysis showed that the heavy metals, vanadium (V), molybdenum (Mo) and nickel (Ni), were present in the carbon black waste in high concentrations. Three human cell lines (HepG2 cells, MRC-5 cells and MDA-MB-231 cells) were used to investigate the toxicity of carbon black waste extract in a variety of in vitro assays. Results from MTS assays indicated that carbon black waste extract decreased the viability of all three cell lines in a dose and time-dependent manner. Observations from confocal microscopy further confirmed this phenomenon. Flow cytometry assay also showed that carbon black waste extract induced apoptosis of human cell lines, and the level of apoptosis increased with increasing waste concentration. Results from reactive oxygen species (ROS) assay indicated that carbon black waste extract induced oxidative stress by increasing intracellular ROS generation in these three human cell lines. Moreover, induction of oxidative damage in these cells was also observed through the alteration of glutathione (GSH) and superoxide dismutase (SOD) activities. Last but not least, by treating the cells with V-spiked solution of concentration equivalent to that found in the carbon black waste extract, V was identified as the main culprit for the high toxicity of carbon black waste extract. These findings could potentially provide insight into the hazards of carbon black waste extract and its toxicity mechanism on human cell lines. PMID- 27694025 TI - Efficient adsorption and antibacterial properties of electrospun CuO-ZnO composite nanofibers for water remediation. AB - On the face of impending global water resources, developing low-cost and efficient water treatment technologies and materials thereof is highly important. Herein, we explore the adsorption capacity and antibacterial properties of CuO ZnO (CZ) composite nanofibers. The ultrafine nanofibers were fabricated using simple and inexpensive electrospinning technique and were further characterized using Field Emission-Scanning Electron Microscope (FE-SEM), Transmission electron microscope (TEM) and X-Ray Diffraction (XRD), Thermogravimetric analysis (TGA), Fourier transform Infrared Spectroscopy (FTIR). When employed as nanoadsorbents, CZ nanofibers exhibited excellent adsorption capacity for congo red dye. Adsorption Isotherms and kinetics were performed to determine the maximum adsorption capacity and the rate of adsorption, respectively, depicting the better efficiency of composite nanofibers as compared to their single counterparts. The mechanism of adsorption is also proposed with the evaluation of diffusion studies. The second part of this study deals with the examination of antibacterial activity of CZ composite nanofibers against antibiotic resistant GFP-E.coli and S. aureus. The antibacterial efficacy was monitored by visual turbidity assay, SEM analysis and reactive oxygen species (ROS) determination. Hence, such nanofibers have been explored as a single platform for the removal of biological as well organic contaminants so as to make them potential in the field of water remediation. PMID- 27694026 TI - Cr(VI) removal via anion exchange on a silver-triazolate MOF. AB - Gram-scale synthesis of a silver-triazolato framework - {[Ag8(tz)6](NO3)2.6H2O}n (1-NO3; tz-=3,5-diphenyl-1,2,4-triazolate) - has been achieved, enabling the systematic investigation of its anion-exchange properties. Our experimental results show that the anion-exchange pattern of 1-NO3 conforms to the so-called Hofmeister bias, which has been correlated to the hydrophobic nature of the MOF pores, and can be understood by considering the difference between the hydration energies of the exchanging anions. Furthermore, 1-NO3 displays a fast, efficient, and reversible adsorption of HCrO4- (via anion-exchange) from Cr(VI)-containing aqueous solution (Qmax=37.0 Cr mg/g, 303K), rendering it a promising prototype of a recyclable MOF for Cr(VI) removal. PMID- 27694027 TI - Increased photocatalytic activity of NiO and ZnO in photodegradation of a model drug aqueous solution: Effect of coupling, supporting, particles size and calcination temperature. AB - Mechanically ball-mill prepared clinoptilolite nanoparticles (NC) were used for increasing photocatalytic activity of NiO and ZnO as alone and binary systems. The semiconductors were supported onto the zeolite during calcination of Ni(II) Zn(II)-exchanged NC at different calcinations temperatures. XRD, FTIR, SEM-EDX, X ray mapping, DRS, TEM and BET techniques were used for characterization of the samples. The calcined catalysts at 400 degrees C for 4h showed the best photocatalytic activity for metronidazole (MNZ) in aqueous solution. The mole ratio of ZnO/NiO affected the photodegradation efficiency because activity of the coupled catalysts depends to the both e/h production and electron scavenging processes. In the used system, NiO acted as e/h production source and ZnO as an electron sink. Red shifts in band gaps of the supported coupled semiconductors was observed whit respect to monocomponent one, confirming formation of nanoparticles of the semiconductors onto the zeolitic bed. The best activities were obtained for the NiO1.3-ZnO1.5/NC (NZ-NC) and NiO0.7-ZnO4.3/NC (NZ3-NC) catalysts at pH 3, 1.2gL-1 of the catalysts and 1gL-1 of MNZ. PMID- 27694028 TI - Carbamazepine degradation by gamma irradiation coupled to biological treatment. AB - Carbamazepine is an emerging contaminant and resistant to biodegradation, which cannot be effectively removed by the conventional biological wastewater treatment processes. In this study, the combined gamma irradiation and biodegradation was employed to remove carbamazepine from wastewater. The effect of dose on the removal of carbamazepine was studied at different doses (300, 600 and 800Gy). The results showed that the removal efficiency of carbamazepine increased with dose increasing during the irradiation process. The maximum removal efficiency was 99.8% at 800Gy, while the removal efficiency of total organic carbon (TOC) was only 26.5%. The removal efficiency of TOC increased to 79.3% after the sequent biological treatment. In addition, several intermediates and organic acids were detected. The possible degradation pathway of carbamazepine during the integrated irradiation and biodegradation was proposed. Based on the overall analysis, the combined gamma irradiation and biological treatment process can be an alternative for removing the recalcitrant organic pollutants such as carbamazepine from wastewater. PMID- 27694029 TI - Leaching mechanisms of constituents from fly ash under the influence of humic acid. AB - As a low-cost material for adsorption, FA is one of the most efficient adsorbents of HA. However, the leaching of elements from FA is problematic during utilization in water treatment. In this investigation, the potential leaching behaviors of Calcium, Arsenic, Born, Chromium, and other elements from FA in HA solution were studied via batch test. The data show that HA had an effect on the leaching of each element of FA, depending on the pH, the initial concentration of HA and the addition of calcium oxide (CaO). The Langmuir isotherm could better fit the equilibrium data in different initial concentrations of HA from 10 to 100mg/L. Because of the interaction between HA and the FA leaching elements, multi-layer adsorption occurred when the initial concentration of HA was more than 100mg/L. The pH and free CaO content played major roles in HA adsorption and FA leaching. Using SEM and XRD to characterize the solid of FA being mixed with CaO treated in solution, the results demonstrated that the reaction between FA and CaO could generate crystal minerals, such as portlandite, gismondine, ettringite (AFt) and calcite, which effectively restrained the leaching of elements, reduced secondary pollution. PMID- 27694030 TI - Conception of a novel spray tower plasma-reactor in a spatial post-discharge configuration: Pollutants remote treatment. AB - This paper describes a novel gliding Arc discharge reactor producing a non thermal plasma at atmospheric pressure in humid air. The ionized gas is generated in a spray-tower absorber for the treatment of organic pollutants. The reactor configuration enables the plasma-degradation of micro-droplets effluents in the spatial post-discharge mode. This type of design allows to exclude the direct contact between the plasma plume and the liquid to be treated in order to avoid the liquid heating and the flame extinction problems. A hydrodynamic study coupling 'Navier-Stokes' equations and those of 'Convection-Diffusion' allowed to calculate the concentration profiles and the droplet falling velocity. The stripping of phenol was studied to valid the hydrodynamic approach. Experiences and simulations showed that after 1h of treatment, only 5% of the compound was transferred into the plasma phase. The spatiality of the novel reactor allowed a degradation rate of 100% for catechol after 38min of plasma-treatment. For 4 nitrophenol, the degradation rate reached 90% after 120min. Phenol and its by products degradation were totally degraded by combining the spatiality of the reactor and the temporal post-discharge. A degradation mechanism was proposed and a plasmachemical reaction in relation with the pernitrous acid species was confirmed.

AB - BACKGROUND: The atrioventricular (AV) dissociation, which is frequently used in differential diagnosis of wide QRS complex tachycardia (WQCT), is the most specific finding of ventricular tachycardia (VT) with lower sensitivity. Herein, we aimed to show the importance of Lewis lead ECG records to detect 'visible p waves' during WQCT. METHOD: A total of 21 consecutive patients who underwent electrophysiologic study (EPS) were included in the study. During EPS, by using a quadripolar diagnostic catheter directed to the right ventricular apex, a fixed stimulus was given and the ventriculoatrial (VA) Wenkebach point was found, and a VT was simulated by a RV apical stimulus at 300ms. The standard and Lewis lead ECG records were taken during this procedure. RESULT: We detected 'visible p waves' in 7 (33.3%) and 14 (66.7%) patients in the standard and Lewis lead ECG groups, respectively. In terms of the 'visible p waves', there was a statistically significant difference between groups (p=0.022). The sensitivity of standard and Lewis lead ECG in determination of the visible p waves was 33.3% and 66.7%, respectively. CONCLUSION: The Lewis lead ECG can be more informative about AV dissociation than the standard 12 lead ECG. As a result, we could suggest the assessment of the Lewis lead ECG recording in addition to the standard 12 lead ECG in differential diagnosis of VT in patients with WQCT. PMID- 27694035 TI - Absence of post-extrasystolic potentiation in takotsubo cardiomyopathy: Another piece of the puzzle? AB - BACKGROUND: Takotsubo cardiomyopathy (TCM) is an intriguing phenomenon characterized by transient and reversible left ventricular (LV) dysfunction despite angiographically unobstructed coronary arteries. The detailed pathophysiology of stunned, viable myocardium in TCM remains to be determined. Post-extrasystolic potentiation (PESP), the phenomenon of enhanced LV contractility following extrasystole, has been used to assess myocardial viability. METHODS: Utilizing a local database, we identified 74 cases that met the modified Mayo Clinic criteria for TCM between October 2004 and March 2016. The patients undergoing left ventriculography were assessed for the presence of fortuitously provoked extrasystoles and the presence or absence of PESP. RESULTS: The baseline characteristics of TCM were 93.2% female patients with median age of 69 and majority cases were apical type (77%). In-hospital mortality was observed in 3 cases (4.1%), all of which were apical type. We observed improved ejection fraction after extrasystole compared to baseline, however stunned myocardium had minimal PESP whereas unaffected myocardium showed marked potentiation. CONCLUSION: Extrasystoles in TCM failed to elicit PESP in affected LV segments despite viability in those segments, in turn implicating a calcium handling abnormality in TCM. Potential explanations of our results may be that catecholamine excess caused maximum calcium release so that an extrasystole could not enhance contractility any further, or that there is a regional insensitivity to calcium release due to a disturbance of the calcium regulatory system at the molecular level despite the bolus of calcium availability provided by the extrasystole. PMID- 27694036 TI - Magnetic properties of single nanomagnets: Electron energy-loss magnetic chiral dichroism on FePt nanoparticles. AB - Electron energy-loss magnetic chiral dichroism (EMCD) allows for the quantification of magnetic properties of materials at the nanometer scale. It is shown that with the support of simulations that help to identify the optimal conditions for a successful experiment and upon implementing measurement routines that effectively reduce the noise floor, EMCD measurements can be pushed towards quantitative magnetic measurements even on individual nanoparticles. With this approach, the ratio of orbital to spin magnetic moments for the Fe atoms in a single L10 ordered FePt nanoparticle is determined to be ml/ms=0.08+/-0.02. This finding is in good quantitative agreement with the results of XMCD ensemble measurements. PMID- 27694037 TI - Fabrication of scanning thermal microscope probe with ultra-thin oxide tip and demonstration of its enhanced performance. AB - With the vigorous development of new nanodevices and nanomaterials, improvements in the quantitation and resolution of the measurement of nanoscale energy transport/conversion phenomena have become increasingly important. Although several new advanced methods for scanning thermal microscopy (SThM) have been developed to meet these needs, such methods require a drastic enhancement of SThM probe performance. In this study, by taking advantage of the characteristics of micromechanical structures where their mechanical stability is maintained even when the film that composes the structures becomes extremely thin, we develop a new design of SThM probe whose tip is made of ultra-thin SiO2 film (~100nm), fabricate the SThM probes, and demonstrate experimentally that the tip radius, thermal time constant, and thermal sensitivity of the probe are all improved. We expect the development of new high-performance SThM probes, along with the advanced measurement methods, to allow the measurement of temperature and thermal properties with higher spatial resolution and quantitative accuracy, ultimately making essential contributions to diverse areas of science and engineering related to the nanoscale energy transport/conversion phenomena.

AB - The mast cells are integral part of immune system and they have pleiotropic physiological functions in our body. Any type of abnormal stimuli causes the mast cells receptors to spur the otherwise innocuous mast cells to degranulate and release inflammatory mediators like histamine, cytokines, chemokines and prostaglandins. These mediators are involved in various diseases like allergy, asthma, mastocytosis, cardiovascular disorders, etc. Herein, we describe the receptors involved in degranulation of mast cells and are broadly divided into four categories: G-protein coupled receptors, ligand gated ion channels, immunoreceptors and pattern recognition receptors. Although, activation of pattern recognition receptors do not cause mast cell degranulation, but result in cytokines production. Degranulation itself is a complex process involving cascade of events like membrane fusion events and various proteins like VAMP, Syntaxins, DOCK5, SNAP-23, MARCKS. Furthermore, we described these mast cell receptors antagonists or agonists useful in treatment of myriad diseases. Like, omalizumab anti-IgE antibody is highly effective in asthma, allergic disorders treatment and recently mechanistic insight of IgE uncovered; matrix mettaloprotease inhibitor marimistat is under phase III trial for inflammation, muscular dystrophy diseases; ZPL-389 (H4 receptor antagonist) is in Phase 2a Clinical Trial for atopic dermatitis and psoriasis; JNJ3851868 an oral H4 receptor antagonist is in phase II clinical development for asthma, rheumatoid arthritis. Therefore, research is still in inchoate stage to uncover mast cell biology, mast cell receptors, their therapeutic role in myriad diseases.

AB - The purpose of the study was to assess the effects and the protective mechanism of konjac oligosaccharide (KOS) on the ulcerative colitis (UC) model induced by 2,4,6-trinitrobenzenesulfonic acid (TNBS) in rats. KOS (1.0 and 4.0g/kg/day) was administered for 14days after the induction of colitis with TNBS. The status of the rats was assessed by morphological and biochemical methods. The effect of KOS on the colonic microflora was also assessed by studying the bacteria profile and short chain fatty acids (SCFAs) production in feces by standard culture techniques and gas chromatography, respectively. KOS administration improved rat weight, colonic length, damage score, structure of gut microbiota, production of SCFA, and reduced colon tissue levels of malondialdehyde (MDA), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor-alpha (TNF alpha), and interleukin-1beta (IL-1beta). Therefore, our results indicate that KOS is an anti-inflammatory and could be useful as a prebiotic to design functional foods for UC. PMID- 27694041 TI - Investigating ego modules involved in TGFbeta3-induced chondrogenesis in mesenchymal stem cells based on ego network. AB - OBJECTIVE: This paper aimed to investigate ego modules for TGFbeta3-induced chondrogenesis in mesenchymal stem cells (MSCs) using ego network algorithm. METHODS: The ego network algorithm comprised three parts, extracting differential expression network (DEN) based on gene expression data and protein-protein interaction (PPI) data; exploring ego genes by reweighting DEN; and searching ego modules by ego gene expansions. Subsequently, permutation test was carried out to evaluate the statistical significance of the ego modules. Finally, pathway enrichment analysis was conducted to investigate ego pathways enriched by the ego modules. RESULTS: A total of 15 ego genes were obtained from the DEN, such as PSMA4, HNRNPM and WDR77. Starting with each ego genes, 15 candidate modules were gained. When setting the thresholds of the area under the receiver operating characteristics curve (AUC) >=0.9 and gene size >=4, three ego modules (Module 3, Module 8 and Module 14) were identified, and all of them had statistical significances between normal and TGFbeta3-induced chondrogenesis in MSCs. By mapping module genes to confirmed pathway database, their ego pathways were detected, Cdc20:Phospho-APC/C mediated degradation of Cyclin A for Module 3, Mitotic G1-G1/S phases for Module 8, and mRNA Splicing for Module 14. CONCLUSIONS: We have successfully identified three ego modules, evaluated their statistical significances and investigated their functional enriched ego pathways. The findings might provide potential biomarkers and give great insights to reveal molecular mechanism underlying this process. PMID- 27694040 TI - LOX-1 and TLR4 affect each other and regulate the generation of ROS in A. fumigatus keratitis. AB - PURPOSE: To explore the relationship between LOX-1 and TLR4 in Aspergillus fumigatus (A. fumigatus) keratitis. To determine LOX-1 and TLR4 can affect each other and regulate inflammation through regulation of the generation of reactive oxygen species (ROS) in A. fumigatus keratitis. METHODS: The cornea and abdominal cavity extracted neutrophils of susceptible C57BL/6 mice were infected with A. fumigatus. The cornea and neutrophils were pretreated with LOX-1 neutralizing antibody, Polyinosinic acid (Poly(I)) (the inhibitor of LOX-1) or CLI-095 (the inhibitor of TLR4) separately before infection. LOX-1, TLR4 and IL-1beta expression were detected in normal and infected cornea by PCR and Western Blot, while ROS was detected in the neutrophils by flow cytometry. RESULTS: LOX-1, TLR4, IL-1beta mRNA and protein levels were up-regulated in C57BL/6 cornea after infection. LOX-1 neutralizing antibody or Poly(I) pretreatment decreased the expression of LOX-1, TLR4 and IL-1beta in C57BL/6 cornea after infection and CLI 095 pretreatment decreased the expression of LOX-1, TLR4 and IL-1beta in C57BL/6 cornea after infection. ROS generation was increased in C57BL/6 neutrophils after infection, however, ROS generation was decreased in C57BL/6 neutrophils after infection by LOX-1 neutralizing antibody or Poly(I) or CLI-095 pretreatment. CONCLUSION: LOX-1, TLR4 and IL-1beta expression and ROS generation are increased after infection. LOX-1 and TLR4 can affect each other and regulate the generation of ROS in A. fumigatus keratitis. Inhibition of LOX-1 and TLR4 can reduce ROS generation. PMID- 27694042 TI - How effective is greening policy in reducing GHG emissions from agriculture? Evidence from Italy. AB - Agriculture contributes significantly to greenhouse gas (GHG) emissions, accounting for more than 10% of total CO2 emissions in the EU-28 area. The Common Agricultural Policy (CAP) plays an important role in promoting environmentally and climate friendly practices and needs to respond to the new environmental challenges by better integrating its objectives with other EU policies. In this respect, the recent CAP reform 2014-2020 made a further step, making a large part of direct payments conditional on new agricultural practices beneficial for the climate and the environment, i.e. "greening". In this study we estimate the potential environmental benefits from greening in terms of GHG emissions in four regions of Northern Italy, one of the major European agricultural areas in terms of emissions. The emissions were quantified and broken down into the three main GHGs (carbon dioxide, methane and nitrous oxide) per production process. This information was subsequently used in a Positive Mathematical Programming (PMP) farm-based model on more than 3,000 farms, to estimate the effects of greening on regional land use and its contribution in reducing the total emissions. The new agri-environmental constraints produce a modest abatement of total emissions of greenhouse gases (-1.5%) in the analyzed area. The model estimates a reduction in CO2 emissions of about 2%. Emissions from nitrous oxide show a decrease of 2.1% and the reduction in the methane is about 0.4% compared to the observed scenario. The process of "lightening" that affected the greening during the CAP negotiation has inevitably resulted in missing an opportunity to introduce a significant positive change of behaviour into agriculture, in line with the expectations and needs of society for EU agriculture as a provider of public goods. PMID- 27694043 TI - Wastewater sludge dewaterability enhancement using hydroxyl aluminum conditioning: Role of aluminum speciation. AB - Chemical conditioning is one of the most important processes for improve the performance of sludge dewatering device. Aluminum salt coagulant has been widely used in wastewater and sludge treatment. It is generally accepted that pre-formed speciation of aluminum salt coagulants (ASC) has an important influence on coagulation/flocculation performance. In this study, the interaction mechanisms between sludge particles and aluminum salt coagulants with different speciation of hydroxy aluminum were investigated by characterizing the changes in morphological and EPS properties. It was found that middle polymer state aluminum (Alb) and high polymer state aluminum (Alc) performed better than monomer aluminum and oligomeric state aluminum (Ala) in reduction of specific resistance to filtration (SRF) and compressibility of wastewater sludge due to their higher charge neutralization and formed more compact flocs. Sludge was significantly acidified after addition Ala, while pH was much more stable under Alb and Alc conditioning due to their hydrolysis stability. The size of sludge flocs conditioned with Alb and Alc was small but flocs structure was denser and more compact, and floc strength is higher, while that formed from Ala is relatively large, but floc structure was loose, floc strength is relatively lower. Scanning environmental microscope analysis revealed that sludge flocs conditioned by Alb and Alc (especially PAC2.5 and Al13) exhibited obvious botryoidal structure, this is because sludge flocs formed by Alb and Alc were more compact and floc strength is high, it was easy generated plentiful tiny channels for water release. In addition, polymeric aluminum salt coagulant (Alb, Alc) had better performance in compressing extracellular polymeric substances (EPS) structure and removing sticky protein-like substances from soluble EPS fraction, contributing to improvement of sludge filtration performance. Therefore, this study provides a novel solution for improving sludge dewatering property by controlling aluminum speciation. PMID- 27694044 TI - Physical activity, black carbon exposure and airway inflammation in an urban adolescent cohort. AB - OBJECTIVE: Regular physical activity can improve cardiopulmonary health; however, increased respiratory rates and tidal volumes during activity may increase the effective internal dose of air pollution exposure. Our objective was to investigate the impact of black carbon (BC) measured by personal sampler on the relationship between physical activity and fractional exhaled nitric oxide (FeNO), a marker of airway inflammation. We hypothesized that higher personal BC would attenuate the protective effect of physical activity on airway inflammation. METHODS: We performed a cross-sectional study nested in a birth cohort of African American and Dominican children living in the Bronx and Northern Manhattan, New York City. Children were recruited based on age (target 9 14 year olds) and presence (n=70) or absence (n=59) of current asthma. Children wore wrist mounted accelerometers for 6 days and were classified as 'active' if they had >=60min of moderate-to-vigorous activity (MVA) each day and 'non-active' if they had <60min of MVA on any given day, based on CDC guidelines. Personal BC measured using a MicroAeth, was assessed during two 24-h periods, at the beginning and end of physical activity assessment. High BC was defined as the upper tertile of BC measured with personal sampler. FeNO measurements were sampled at the beginning and end of the of physical activity assessment. RESULTS: In multivariable linear regression models, 'active' children had 25% higher personal BC concentrations (p=0.02) and 20% lower FeNO (p=0.04) compared to 'non active' children. Among children with high personal BC (n=33), there was no relationship between activity and FeNO (p=1.00). The significant protective relationship between activity and airway inflammation was largely driven by children with lower personal BC (n=96, p=0.04). CONCLUSIONS: Children that live in an urban environment and are physically active on a daily basis have higher personal exposure to BC. High BC offsets the protective relationship between physical activity and airway inflammation. PMID- 27694046 TI - Linking toxicity profiles to pollutants in sludge and sediments. AB - Obtaining a complex picture of how pollutants synergistically influence toxicity of a system requires statistical correlation of chemical and ecotoxicological data. In this study, we determined concentrations of eight potentially toxic metals (PTMs) and four groups of organic pollutants in 15 sewage sludge and 12 river sediment samples, then linked measured contaminant concentrations to the toxicity of each matrix through constrained correspondence analysis (CCA). In sludge samples, Hg, As, hexachlorohexane (HCH), polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD) influenced the toxicity profiles, with the first four having significant effects and HBCD being marginally significant. In sediment samples, Hg, As, PBDEs, hexachlorobenzene (HCB), dichlorodiphenyltrichloroethane (DDT), HBCD, HCH and polycyclic aromatic hydrocarbons (PAHs) were found to explain toxicity profiles with Hg, As, PBDEs, HCB, DDT, HBCD, and HCH having significant effects and PAHs being marginally significant. Interestingly, HCH was present in small amounts yet proved to have a significant impact on toxicity. To the contrary, PAHs were often present in high amounts, yet proved to be only marginally significant for sediment toxicity. These results indicate that statistical correlation of chemical and ecotoxicological data can provide more detailed understanding of the role played by specific pollutants in shaping toxicity of sludge and sediments. PMID- 27694045 TI - Dietary selenium disrupts hepatic triglyceride stores and transcriptional networks associated with growth and Notch signaling in juvenile rainbow trout. AB - Dietary Se has been shown to adversely affect adult fish by altering growth rates and metabolism. To determine the underlying mechanisms associated with these observations, we measured biochemical and transcriptomic endpoints in rainbow trout following dietary Se exposures. Treatment groups of juvenile rainbow trout were fed either control Lumbriculus variegatus worms or worms cultured on selenized yeast. Selenized yeast was cultured at four nominal doses of 5, 10, 20 or 40mg/kg Se dry weight (measured dose in the worms of 7.1, 10.7, 19.5, and 31.8mg/kgSedw respectively) and fish were fed for 60days. At 60 d, hepatic triglycerides, glycogen, total glutathione, 8-isoprostane and the transcriptome response in the liver (n=8/group) were measured. Fish fed the nominal dose of 20 and 40mg/kg Se dry weight had lower body weight and a shorter length, as well as lower triglyceride in the liver compared to controls. Evidence was lacking for an oxidative stress response and there was no change in total glutathione, 8 isoprostane levels, nor relative mRNA levels for glutathione peroxidase isoforms among groups. Microarray analysis revealed that molecular networks for long-chain fatty acid transport, lipid transport, and low density lipid oxidation were increased in the liver of fish fed 40mg/kg, and this is hypothesized to be associated with the lower triglyceride levels in these fish. In addition, up regulated gene networks in the liver of 40mg/kg Se treated fish included epidermal growth factor receptor signaling, growth hormone receptor, and insulin growth factor receptor 1 signaling pathways. These molecular changes are hypothesized to be compensatory and related to impaired growth. A gene network related to Notch signaling, which is involved in cell-cell communication and gene transcription regulation, was also increased in the liver following dietary treatments with both 20 and 40mg/kg Se. Transcriptomic data support the hypothesis that dietary Se increases the expression of networks for growth related signaling cascades in addition to those related to fatty acid synthesis and metabolism. We propose that the disruption of metabolites related to triglyceride processing and storage, as well as gene networks for epidermal growth factor and Notch signaling in the liver, represent key molecular initiating events for adverse outcomes related to growth and Se toxicity in fish. PMID- 27694047 TI - Degradation mechanisms of DDX induced by the addition of toluene and glycerol as cosubstrates in a zero-valent iron pretreated soil. AB - Abiotic and biotic processes can be used to remediate DDX (DDT, DDD, DDE, and DDNS) contaminated soils; these processes can be fostered using specific carbon amendments to stimulate particular soil indigenous microbial communities to improve rates or extent of degradation. In this study, toluene and glycerol were evaluated as cosubstrates under aerobic and anoxic conditions to determine the degradation efficiencies of DDX and to elucidate possible degradation mechanisms. Slurry microcosms experiments were performed during 60 days using pretreated soil with zero-valent iron (ZVI). Toluene addition enhanced the percentage of degradation of DDX. DDNS was the main compound degraded (around 86%) under aerobic conditions, suggesting cometabolic degradation of DDX by toluene degrading soil bacteria. Glycerol addition under anoxic conditions favored the abiotic degradation of DDX mediated by sulfate-reducing bacteria activity, where DDT was the main compound degraded (around 90%). The 16S rDNA metagenomic analyses revealed Rhodococcus ruber and Desulfosporosinus auripigmenti as the predominant bacterial species after 40 days of treatment with toluene and glycerol additions, respectively. This study provides evidence of biotic and abiotic DDX degradation by the addition of toluene and glycerol as cosubstrates in ZVI pretreated DDX-contaminated soil. PMID- 27694048 TI - Gallic acid grafting modulates the oxidative potential of ferrimagnetic bioactive glass-ceramic SC-45. AB - Magnetite-containing glass-ceramics are promising bio-materials for replacing bone tissue after tumour resection. Thanks to their ferrimagnetic properties, they generate heat when subjected to an alternated magnetic field. In virtue of this they can be employed for the hyperthermic treatment of cancer. Moreover, grafting anti-cancer drugs onto their surface produces specific anti-neoplastic activity in these biomaterials. Gallic acid (GA) exhibits antiproliferative activity which renders it a promising candidate for anticancer applications. In the present paper, the reactivity of ferrimagnetic glass-ceramic SC-45 grafted with GA (SC-45+GA) was studied in terms of ROS release, rupture of the C-H bond of the formate molecule and Fenton reactivity by EPR/spin trapping in acellular systems. The ability of these materials to cause lipid peroxidation was assessed by UV-vis/TBA assay employing linoleic acid as a model of membrane lipid. The results, compared to those obtained with SC-45, showed that GA grafting (i) significantly enhanced the Fenton reactivity and (ii) restored the former reactivity of SC-45 towards both the C-H bond and linoleic acid which had been completely suppressed by prolonged contact with water. Fe2+ centres at the surface are probably implicated. GA, acting as a pro-oxidant, reduces Fe3+ to Fe2+ by maintaining a supply of Fe2+ at the surface of SC-45+GA. PMID- 27694050 TI - Biopolymeric hydrogels - nanostructured TiO2 hybrid materials as potential injectable scaffolds for bone regeneration. AB - The present work aims at development of novel hybrid materials from genipin crosslinked collagen or collagen/chitosan hydrogels containing various types of TiO2 nanoparticles characterized with different anatase/rutile ratios. Collagen and chitosan were selected as hydrogel components since they are biopolymers being, like collagen, the major compound present in extracellular matrix or exhibit structural similarity to glycosaminoglycans, like chitosan. TiO2 nanoparticles were introduced to the hydrogel matrices to improve their mechanical properties as well as bioactivity. A series of twelve novel hybrid materials were prepared and their physicochemical, mechanical and biological properties were evaluated. It was found that TiO2 nanostructures introduced to the hydrogels have significant influence on the swelling properties of the synthesized hybrids and their impact is strongly dependent on the type of matrices. The surfaces of hybrid materials were found to be more hydrophilic than these of corresponding hydrogel matrix. It was also observed that, the storage modulus values of the hybrids based on collagen-chitosan hydrogel are comparable to these for plain hydrogels what indicates that the mechanical properties of the materials obtained are satisfactory for possible biomedical application. The in vitro cell culture studies have shown that prepared materials are biocompatible as they can support mitochondrial activity of MEFs as well as MG-63 cells. In vitro experiments performed under simulated body fluid (SBF) conditions have revealed that all studied TiO2 nanoparticles present in hydrogel matrices, regardless of anatase/rutile ratio, successfully induced formation of apatite like structures. The hybrid materials developed here are promising candidates for preparation of bioactive, injectable scaffolds for tissue engineering. PMID- 27694049 TI - Toxicity mechanism of titanium dioxide and zinc oxide nanoparticles against food pathogens. AB - Food preservation is an important field of research. It extends the shelf life of major food products. Our current study is based on food preservation through TiO2 and ZnO nanoparticles. TiO2 and ZnO are biocompatible nanomaterial. The biocompatibility of the materials were established through toxicity studies on cell lines. Titanium dioxide and Zinc Oxide nanoparticle were synthesized by wet chemical process. They are characterized by X-Ray diffraction and TEM. The antibacterial activities of both the materials were analysed to ensure their effectiveness as food preservative against Salmonella typhi, Klebsiella pneumoniae and Shigella flexneri. The results indicates that TiO2 and ZnO nanoparticle inhibits Salmonella, Klebsiella and Shigella. The mode of action is by the generation of ROS in cases of Salmonella, Klebsiella. Mode of action in Shigella is still unclear. It was also proved that TiO2 and ZnO nanoparticle are biocompatible materials. PMID- 27694051 TI - Resveratrol induces chain interdigitation in DPPC cell membrane model systems. AB - Resveratrol is a natural polyphenol found in various plants with potential therapeutic activity as anti-oxidant, anti-inflammatory, cardioprotective and anti-tumoral. Lipid membranes are among cellular components that are targets of its action. In this work ESR of chain labeled lipids, calorimetry, X-ray diffraction and molecular docking are used to study the interaction of resveratrol with membrane model systems of dipalmitoylphosphatidylcholine (DPPC) as a function of resveratrol concentration (0-30 mol% of the lipid) and temperature (10-50 degrees C). Resveratrol incorporated in DPPC bilayers induces considerable motional restriction at the lipid tail termini, removing the gradient of increasing mobility along the chain found in DPPC bilayers in the gel phase. In contrast, it leaves unperturbed the DPPC chain flexibility profile in the liquid-crystalline phase. At low concentration, resveratrol progressively reduces the pre-transition temperature and eliminates the pre-transition for content >=5mol%. A reduced cooperativity and a downshift of the main transition temperature are observed, especially at high content. The typical diffraction pattern of DPPC multibilayers in the Lbeta' phase is converted to a lamellar pattern with reduced d-spacing of untilted lipid chain in a hexagonal packing at 30 mol% of resveratrol. Molecular docking indicates that the energetically favoured anchoring site is the polar headgroup region, where resveratrol acts as a spacer. The overall results are consistent with the formation in DPPC of an interdigitated Lbetai gel phase induced by 30 mol% resveratrol. PMID- 27694052 TI - Influence of solution chemistry on the inactivation of particle-associated viruses by UV irradiation. AB - MS2 inactivation by UV irradiance was investigated with the focus on how the disinfection efficacy is influenced by bacteriophage MS2 aggregation and adsorption to particles in solutions with different compositions. Kaolinite and Microcystis aeruginosa were used as model inorganic and organic particles, respectively. In the absence of model particles, MS2 aggregates formed in either 1mM NaCl at pH=3 or 50-200mM ionic strength CaCl2 solutions at pH=7 led to a decrease in the MS2 inactivation efficacy because the virions located inside the aggregate were protected from the UV irradiation. In the presence of kaolinite and Microcystis aeruginosa, MS2 adsorbed onto the particles in either 1mM NaCl at pH=3 or 50-200mM CaCl2 solutions at pH=7. In contrast to MS2 aggregates formed without the presence of particles, more MS2 virions adsorbed on these particles were exposed to UV irradiation to allow an increase in MS2 inactivation. In either 1mM NaCl at pH from 4 to 8 or 2-200mM NaCl solutions at pH=7, the absence of MS2 aggregation and adsorption onto the model particles explained why MS2 inactivation was not influenced by pH, ionic strength, and the presence of model particles in these conditions. The influence of virus adsorption and aggregation on the UV disinfection efficiency found in this research suggests the necessity of accounting for particles and cation composition in virus inactivation for drinking water. PMID- 27694055 TI - Comparative assessment of cardiac activity and DNA damage in haemocytes of the Mediterranean mussel Mytilus galloprovincialis in exposure to tributyltin chloride. AB - This study gives an insight in sensitivity of heart rate (Hr) of Mytilus galloprovincialis as a physiological biomarker. Impact of tributyltin chloride (TBT-Cl) on Hr was studied in parallel with evaluation of mutagenic, genotoxic and cytotoxic potential of TBT-Cl (10, 100 and 1000MUg/L) within 96h treatment in static conditions. Mutagenic potential was assessed by SOS/umuC assay while genotoxicity was assessed in haemocytes of M. galloprovincialis by using the comet assay and the micronucleus test. Benzo(a)pyrene (B(a)P) was used as a positive control. Hr variations detected in TBT-Cl treatments can be linked to data obtained in the genotoxicological assays indicating that Hr can be considered and used as a reliable physiological biomarker for detecting the presence of organotin compounds. However despite the observed genotoxic potential of B(a)P, a noteworthy Hr response was not observed which further questions the potential of Hr in the detection of different types of pollutants. PMID- 27694053 TI - Selective anticancer activity of hydroxyapatite/chitosan-poly(d,l)-lactide-co glycolide particles loaded with an androstane-based cancer inhibitor. AB - In an earlier study we demonstrated that hydroxyapatite nanoparticles coated with chitosan-poly(d,l)-lactide-co-glycolide (HAp/Ch-PLGA) target lungs following their intravenous injection into mice. In this study we utilize an emulsification process and freeze drying to load the composite HAp/Ch-PLGA particles with 17beta hydroxy-17alpha-picolyl-androst-5-en-3beta-yl-acetate (A), a chemotherapeutic derivative of androstane and a novel compound with a selective anticancer activity against lung cancer cells. 1H NMR and 13C NMR techniques confirmed the intact structure of the derivative A following its entrapment within HAp/Ch-PLGA particles. The thermogravimetric and differential thermal analyses coupled with mass spectrometry were used to assess the thermal degradation products and properties of A-loaded HAp/Ch-PLGA. The loading efficiency, as indicated by the comparison of enthalpies of phase transitions in pure A and A-loaded HAp/Ch-PLGA, equaled 7.47wt.%. The release of A from HAp/Ch-PLGA was sustained, neither exhibiting a burst release nor plateauing after three weeks. Atomic force microscopy and particle size distribution analyses were used to confirm that the particles were spherical with a uniform size distribution of d50=168nm. In vitro cytotoxicity testing of A-loaded HAp/Ch-PLGA using MTT and trypan blue dye exclusion assays demonstrated that the particles were cytotoxic to the A549 human lung carcinoma cell line (46+/-2%), while simultaneously preserving high viability (83+/-3%) of regular MRC5 human lung fibroblasts and causing no harm to primary mouse lung fibroblasts. In conclusion, composite A-loaded HAp/Ch-PLGA particles could be seen as promising drug delivery platforms for selective cancer therapies, targeting malignant cells for destruction, while having a significantly lesser cytotoxic effect on the healthy cells. PMID- 27694054 TI - The biological activity of cationic liposomes in drug delivery and toxicity test in animal models. AB - In the study we made use of DOTAP (1,2-dioleoyl-3-trimethylammonium), DOPE (1,2 dioleoyl-snglycero-3-phosphoethanolamine) and PEG-PE (polyethylene glycol- polyethylene) to make cationic PEG-liposomes by ultrasonic dispersion method. The plasmid pGPU6 combined with cationic PEG-liposomes or Liopofectamin 2000 was used to transfect PC3 cells to judge the transfection efficiency. HE staining showed that the pGUP6-shAurora B plasmid/liposomes complex could significantly inhibit tumor growth in mice tumor model. The results indicated that there was no remarkable difference between the homemade liposomes and Lipofectamin 2000 after transfection, with transfection efficiency over 80%. And the homemade liposomes also had high transfection efficiency in vivo. No significant side effects were observed on weight, coat condition, behavior or appetite and the life span of mice treated with pGPU6-shAurora B were extended. Beyond that, there were no differences in mortality or in pathological changes to the heart, liver, spleen, lungs and kidneys among all the mice. PMID- 27694056 TI - Copper-64 labeled liposomes for imaging bone marrow. AB - INTRODUCTION: Bone marrow is the soft tissue compartment inside the bones made up of hematopoietic cells, adipocytes, stromal cells, phagocytic cells, stem cells, and sinusoids. While [18F]-FLT has been utilized to image proliferative marrow, to date, there are no reports of particle based positron emission tomography (PET) imaging agents for imaging bone marrow. We have developed copper-64 labeled liposomal formulation that selectively targets bone marrow and therefore serves as an efficient PET probe for imaging bone marrow. METHODS: Optimized liposomal formulations were prepared with succinyl PE, DSPC, cholesterol, and mPEG-DSPE (69:39:1:10:0.1) with diameters of 90 and 140nm, and were doped with DOTA-Bn-DSPE for stable 64Cu incorporation into liposomes. RESULTS: PET imaging and biodistribution studies with 64Cu-labeled liposomes indicate that accumulation in bone marrow was as high as 15.18+/-3.69%ID/g for 90nm liposomes and 7.01+/ 0.92%ID/g for 140nm liposomes at 24h post-administration. In vivo biodistribution studies in tumor-bearing mice indicate that the uptake of 90nm particles is approximately 0.89+/-0.48%ID/g in tumor and 14.22+/-8.07%ID/g in bone marrow, but respective values for Doxil(r) like liposomes are 0.83+/-0.49%ID/g and 2.23+/ 1.00%ID/g. CONCLUSION: Our results indicate that our novel PET labeled liposomes target bone marrow with very high efficiency and therefore can function as efficient bone marrow imaging agents. PMID- 27694057 TI - Melanoma targeting with [99mTc(N)(PNP3)]-labeled alpha-melanocyte stimulating hormone peptide analogs: Effects of cyclization on the radiopharmaceutical properties. AB - The purpose of this study was to evaluate the effect of cyclization on the biological profile of a [99mTc(N)(PNP3)]-labeled alpha-melanocyte stimulating hormone peptide analog. A lactam bridge-cyclized H-Cys-Ahx-betaAla3-c[Lys4-Glu His-D-Phe-Arg-Trp-Glu10]-Arg11-Pro-Val-NH2 (NAP-NS2) and the corresponding linear H-Cys-Ahx-betaAla-Nle-Asp-His-D-Phe-Arg-Trp-Gly-NH2 (NAP-NS1) peptide were synthetized, characterized by ESI-MS spectroscopy and their melanocortin-1 receptor (MC1R) binding affinity was determined in B16/F10 melanoma cells. The consistent [99mTc(N)(PNP3)]-labeled compounds were readily obtained in high specific activity and their stability and biological properties were assessed. As an example, the chemical identity of [99mTc(N)(NAP-NS1)(PNP3)]+ was confirmed by carrier added experiments supported by radio/UV HPLC analysis combined with ESI(+)-MS. Compared with the linear peptide, cyclization negatively affected the biological properties of NAP-NS2 peptide by reducing its binding affinity for MC1R and by decreasing the overall excretion rate of the corresponding [99mTc(N)(PNP3)]-labeled peptide from the body as well as its in vivo stability. [99mTc(N)(NAP-NS1)(PNP3)]+ was evaluated for its potential as melanoma imaging probe in murine melanoma model. Data from in vitro and in vivo studies on B16/F10 melanoma model of [99mTc(N)(NAP-NS1)(PNP3)]+ clearly evidenced that the radiolabeled linear peptide keeps its biological properties up on the conjugation to the [99mTc(N)(PNP3)]-building block. The progressive increase of the tumor-to nontarget ratios over the time indicates a quite stable interaction between the radio-complex and the MC1R. PMID- 27694060 TI - Dynamic gait stability of treadmill versus overground walking in young adults. AB - Treadmill has been broadly used in laboratory and rehabilitation settings for the purpose of facilitating human locomotion analysis and gait training. The objective of this study was to determine whether dynamic gait stability differs or resembles between the two walking conditions (overground vs. treadmill) among young adults. Fifty-four healthy young adults (age: 23.9+/-4.7years) participated in this study. Each participant completed five trials of overground walking followed by five trials of treadmill walking at a self-selected speed while their full body kinematics were gathered by a motion capture system. The spatiotemporal gait parameters and dynamic gait stability were compared between the two walking conditions. The results revealed that participants adopted a "cautious gait" on the treadmill compared with over ground in response to the possible inherent challenges to balance imposed by treadmill walking. The cautious gait, which was achieved by walking slower with a shorter step length, less backward leaning trunk, shortened single stance phase, prolonged double stance phase, and more flatfoot landing, ensures the comparable dynamic stability between the two walking conditions. This study could provide insightful information about dynamic gait stability control during treadmill ambulation in young adults.

AB - INTRODUCTION: Targeted radiotherapy using the bifunctional chelate approach with 186/188Re(V) is challenging because of the susceptibility of monooxorhenium(V) based complexes to oxidize in vivo at high dilution. A monoamine-monoamide dithiol (MAMA)-based bifunctional chelating agent was evaluated with both rhenium and technetium to determine its utility for in vivo applications. METHODS: A 222 MAMA chelator, 222-MAMA(N-6-Ahx-OEt) bifunctional chelator, and 222-MAMA(N-6-Ahx BBN(7-14)NH2) were synthesized, complexed with rhenium, radiolabeled with 99mTc and 186Re (carrier added and no carrier added), and evaluated in initial biological distribution studies. RESULTS: An IC50 value of 2.0+/-0.7nM for natReO 222-MAMA(N-6-Ahx-BBN(7-14)NH2) compared to [125I]-Tyr4-BBN(NH2) was determined through competitive cell binding assays with PC-3 tumor cells. In vivo evaluation of the no-carrier added 99mTc-222-N2S2(N-6-Ahx-BBN(7-14)NH2) complex showed little gastric uptake and blockable pancreatic uptake in normal mice. CONCLUSIONS: The 186ReO-222-N2S2(N-6-Ahx-BBN(7-14)NH2) complex showed stability in biological media, which indicates that the 222-N2S2 chelator is appropriate for chelating 186/188Re in radiopharmaceuticals involving peptides. Additionally, the in vitro cell studies showed that the ReO-222-N2S2(N-6-Ahx-BBN(7-14)NH2) complex (macroscopically) bound to PC3-tumor cell surface receptors with high affinity. The 99mTc analog was stable in vivo and exhibited pancreatic uptake in mice that was blockable, indicating BB2r targeting. PMID- 27694059 TI - Comparison of AUDIT-C collected via electronic medical record and self administered research survey in HIV infected and uninfected patients. AB - BACKGROUND: Using electronic medical record (EMR) data for clinical decisions, quality improvement, and research is common. While unhealthy alcohol use is particularly risky among HIV infected individuals (HIV+), the validity of EMR data for identifying unhealthy alcohol use among HIV+ is unclear. Among HIV+ and uninfected, we: (1) assess agreement of EMR and research AUDIT-C at validated cutoffs for unhealthy alcohol use; (2) explore EMR cutoffs that maximize agreement; and (3) assess subpopulation variation in agreement. METHODS: Using data from the Veterans Aging Cohort Study (VACS), EMR AUDIT-C cutoffs of 2+, 3+, and 4+ for men (2+ and 3+ for women) were compared to research AUDIT-C 4+ for men (3+ for women). Agreement was compared by demographics, HIV, hepatitis C infection, and alcohol related diagnosis. RESULTS: Among 1082 HIV+ and 1160 uninfected men, 14% and 22% had an EMR and research AUDIT-C 4+, respectively. Among 32 HIV+ and 115 uninfected women, 9% and 14% had an EMR and research AUDIT C 3+. For men, EMR agreement with the research AUDIT-C 4+ was highest at a cutoff of 3+ (kappa=0.49). For women, EMR agreement with AUDIT-C 3+ was highest at a cutoff of 2+ (kappa=0.46). Moderate agreement was consistent across subgroups. CONCLUSIONS: EMR AUDIT-C underestimates unhealthy alcohol use compared to research AUDIT-C in both HIV+ and uninfected individuals. Methods for improving quality of clinical screening may be in need of investigation. Researchers and clinicians may consider alternative EMR cutoffs that maximize agreement given limitations of clinical screening.

PMID- 27694061 TI - Antibiofilm effect of warfarin on biofilm formation of Escherichia coli promoted by antimicrobial treatment. AB - Enhancement of microbial biofilm formation by low antimicrobial doses is a critical problem in the medical field. The objective of this study was to propose a new drug candidate against the biofilm formation promoted by subinhibitory dose of antimicrobials. To determine the effect on biofilm formation of Escherichia coli, a subinhibitory concentration of lactoferrin (LF), a milk protein involved in a broad range of biological properties including antimicrobial action, or ampicillin (AMP), a typical antibiotic, was added to an E. coli cell culture in a 96-well microtiter plate. On the other hand, warfarin (WARF), an oral anticoagulant, or polymyxin B (PMB), a strong antibiotic for biofilm treatment, was added as an antagonist against the biofilm promoted by LF or AMP. The amount of biofilm formed at 100MUg/mL LF in lysogeny broth medium was four times higher than in the absence of LF. Meanwhile, it was found that WARF suppressed the LF promoted biofilm formation to a level comparable with the LF-free condition. WARF worked in a similar manner to PMB, which is known as an antibiofilm agent. Furthermore, WARF could also suppress the biofilm promoted by AMP. In conclusion, this study suggests that WARF can work as an antibiofilm agent against the biofilm formation promoted by subinhibitory dose of antimicrobials. PMID- 27694063 TI - Appropriate proton pump inhibitors use in elderly outpatients according to recommendations. AB - : Proton pump inhibitors (PPI) are widely prescribed, particularly in elderly patients, and their side effects are underestimated. Recommendations of the french health authorities, some specific to the elderly, specify their indications. The main objective of this descriptive and prospective study was to assess in elderly patients the adequacy of PPI prescriptions to these recommendations and to the marketing authorization. METHODS: Analysis of all patients hospitalized in an acute geriatric unit over a period of 2 years for which the drug prescription on admission included a PPI. RESULTS: For the 125 patients included (mean age 84 years), the PPI treatment period exceeded one year in 68% of cases and 49.6% of PPI prescriptions were not consistent with the recommendations; not recommended indications are mainly prevention of gastroduodenal lesions in case of antiplatelet, VKA or corticosteroid treatment (24%), anemia (12%) or epigastric pain (8.5%) without prior endoscopic exploration. Only 50.4% of patients treated with PPI had an upper gastro intestinal endoscopy, which should be systematically performed in patients over 65 years according to the recommendations. CONCLUSION: Our study confirms the low appropriateness of PPI prescriptions, particularly in elderly patients. This can be explained by controversial issues or by difficulties in adapting these recommendations in geriatric practice. PMID- 27694064 TI - Elderly and preventive care of the geriatric pathologies in African environment. AB - Senegal will not be spared by the process of the aging of its population. In fact, according to surveys, the demographic increase in the population of the old people, which is 3.5% higher than the national average (2.5%). But for the time being, gerontology problems are not arising in terms of demographic weight, but rather in terms of the breaking up of solidarity networks, uncontrolled urbanization and poverty. As far as health is concerned, the old people generally are faced with the same problems as their Northern counterparts; they are exposed to chronic diseases that demand their taking in charge in a long period of time. Besides, these diseases are a great handicap and they are also disabling diseases. So taking them in charge puts a financial on their meager family budgets or their pensions. In addition, there are no specialists in geriatrics, and those working in the field did not receive any training for that. Moreover, most of our health facilities are lacking in diagnostic means. Therefore, gerontology-geriatrics solutions that are adapted to our socio-economic context should be assigned straight away. The problem is not about stopping the process of aging, which, as a physiological process, is inevitable and irreversible, but rather delaying its effects. The matter at issue will be about how to set up a decentralized and integrated program that is designed to fight against geriatric diseases and disorders and that mainly focuses on screening and primary and secondary prevention, for our low financial resources and the low medical equipment of our health facilities cannot help us to adequately take charge of complications related to these diseases.

AB - Martinique was accepted as an associate member by the Council of Ministers of the Organization of Eastern Caribbean State since February 2015. This membership constitutes a major asset in bringing Martiniquais closer to the other Caribbean populations and should play a key role as it relates to regional cooperation especially in the domain of healthcare. Martinique and several Caribbean countries share common health issues such as; dengue, chikungunya virus, Zika Virus leptospirosis, snakebite, severe cardiovascular diseases (CVD), HTLV-1, sickle cell diseases and so on. This medical cooperation is mainly based in three important areas: training, teaching and transport (medical evacuations). The Inter-regional cooperation between the French Departments of the Americas and all other Caribbean countries is essential for the implementation and improvement of health care. It is urgent for the Caribbean professionals to discuss the possibilities of developing common solid relationships in training, collective scientific research, and continuous medical education.

AB - To assess the prevalence of senile cataracts and the awareness and attitudes of patients with them in a rural area in Togo. We conducted a 10-weeks cross sectional ophthalmic screening in the prefecture of VO, 57 km from Lome, which sought to include individuals aged 50 years and older living in the study area. All patients underwent a comprehensive ophthalmic examination. Of the 3111 patients expected, 767 came for the examination, for a participation rate of 24.6%. The sex ratio was 0.8, and the patients' mean age was 60.1 +/- 8.7 years. The frequency of senile cataracts was 40.28%. Women had cataracts more often than men, with a sex ratio of 0.63. The frequency of unilateral blindness was 1.62% and 22% for bilateral blindness related to cataracts. Almost every participant (99.7%) knew the disease named cataract, but fewer than half (41.59%) knew its causes. Most patients (97.09%) accepted the idea of cataract surgery, but the lack of financial resources was a major barrier to it (64.72%). The frequency of senile cataracts is high in rural area. Decentralization of eye care is essential to give the right to sight to the population living in these areas. PMID- 27694081 TI - Tuberculosis in hemodialysis. AB - Chronic uremia puts patients at increased risk of infectious complications, in particular, tuberculosis. In this prospective study, we analyzed the clinical, paraclinical, and therapeutic features as well as outcome for all patients on chronic hemodialysis with tuberculosis from January 2010 through August 2012. Sixty-one patients were admitted for bacterial infections, 23% of them for tuberculosis. Fever was present in 71% of cases, and CRP elevated in all cases. The tuberculin skin test was positive in only 2 of 9 cases, and Mycobacterium tuberculosis isolated in 2 of 10 cases. Histological evidence was obtained in 7 of 9 cases. Plain radiographs and computed tomography evoked tuberculosis. The location was extrapulmonary in 71% of cases. Chemotherapy for tuberculosis was based on a quadruple therapy for 10 patients and triple therapy for 3. The outcome was favorable in 11 patients and fatal for 3. Tuberculosis is much more common in hemodialysis patients than in the general population. The telltale signs are nonspecific. Prognosis is closely linked to early diagnosis and treatment. PMID- 27694082 TI - Prevalence of schistosomiasis and soil-transmitted helminth infections among schoolchildren in Burkina Faso. AB - To determine the current status of schistosomiasis and soil-transmitted helminth (STH) infections among schoolchildren after 10 years of mass treatment with praziquantel. Parasitological surveys were conducted in 2013 in 22 primary schools located in 11 regions of Burkina Faso. Urine filtration methods and Kato Katz techniques for stool were used to detect the eggs of Schistosoma haematobium, Schistosoma mansoni, and STH. 3514 schoolchildren aged from 7 to 11 (1.415 +/- 9) years participated in the study. The prevalence of S. haematobium was 8.1% and of S. mansoni, 1.2%. The prevalence of intestinal schistosomiasis ranged from 0.6% to 26.2% and that of urinary schistosomiasis from 0.6% to 56.2%. The prevalence of hookworms was 1.1%, Ascaris lumbricoides 0.1%, and Trichuris trichiura 0.06%. The arithmetic mean of S. haematobium and S. mansoni were respectively 6 eggs/10 mL and 1.07 epg (eggs per gram). The arithmetic means of eggs were 0.07 epg, 0.03 epg, and 1.89 epg respectively for A. lumbricoides, T. trichiura, and Ankylostoma spp. This study shows the current situation for schistosomiasis and STH infections in different regions of Burkina Faso. Elimination of this parasitic disease requires the inclusion of other control methods, in addition to mass treatment. PMID- 27694083 TI - The relational dimension of care for maternity blues and its relation to decompensation of a psychiatric disorder during the intermediate postpartum period in Cameroon. AB - In a setting such as Cameroon, where perinatal care offers few services for women with psychiatric problems during pregnancy, delivery, and the immediate postpartum period, the development of the relational dimension of care may help prevent severe psychiatric disorders . This study evaluates the role of the relational dimension of perinatal and early postpartum care (providing perinatal counseling and a space to speak) on women with blues on the intermediate-term outcomes of decompensation, in view of the importance of the emotional issues occurring in the perinatal period. Data collection used both diagnostic and clinical methods on a sample of 50 women from three hospitals in Cameroon who gave birth during the study period and agreed to participate. Of the 38 diagnosed with blues, 10 were available for observation during the intermediate post partum: they were sorted into an experimental group that received perinatal counseling (n=5) and a control group that did not. The results suggest the importance to women with blues of a space for talking during the post-partum period. In particular, the quality of this counseling, in terms of the emotional responses of the nursing staff, determines the outcome of this management and can help to reduce the outset of depression and decompensation. PMID- 27694084 TI - Prevalence of Helicobacter pylori prevalence and upper gastrointestinal endoscopy in HIV/AIDS patients with gastrointestinal symptoms in the University Teaching Hospitals in Cameroon. AB - OBJECTIVE: To determine the prevalence of Helicobacter pylori (H. pylori) infection and of various upper gastrointestinal (GI) lesions in HIV+ patients with GI symptoms and the relation of H. pylori infection to CD4 cell counts. MATERIAL AND METHODS: In all, 56 HIV+ patients and 56 age- and sex-matched HIV- controls, all with upper GI symptoms, were evaluated by an upper endoscopy examination and gastric biopsy. H. pylori status was assessed with a urease test and histology. HIV was diagnosed with the rapid test and enzyme-linked immunosorbent assay (ELISA). RESULTS: The prevalence of H. pylori was 50% (28/56 [95%CI 36.3-63.7]) in HIV+ subjects and 55% (31/56 [95%CI 41.5-68.7]) in HIV- controls (p = 0.57). H. pylori infection rates did not differ significantly in HIV+ patients between those with a CD4 count >=200/mm3 (52%) and those with a CD4 count <200/mm3 (42%) (p = 0.62). The prevalence on endoscopy of specific lesions in HIV+ patients and controls were compared: esophageal candidiasis (61%, 34/56 vs. 7%; p<0.0001), esophageal ulcers (18%, 10/56 vs 2%; p = 0.01), corpus gastritis (41%; 23/56 vs 5%; p<0.0001), and duodenitis (20%, 11/56, vs 0%; p = 0.001). CONCLUSIONS: The prevalence rate of H. pylori did not differ significantly between HIV+ and HIV- subjects. Prevalence of H. pylori was also lower, although not significantly, among HIV+ patients with CD4 T-cell counts below 200/mm3. On endoscopy, esophageal candidiasis was the most common finding in HIV+ patients, discovered by dysphagia. PMID- 27694085 TI - Inappropriate bradycardia in Ebola virus disease. AB - BACKGROUND: As part of French assistance for the outbreak of Ebola virus disease in west Africa, a military treatment center for infected healthcare workers was deployed in Conakry, Guinea. Although some cases of bradycardia have been reported since the first Ebola outbreak, they have never been documented to our knowledge. We studied heart rhythm in patients with Ebola virus disease to analyze inappropriate bradycardia and discuss its mechanism. METHODS: Nine patients who tested positive for Ebola were admitted in March 2015. Baseline clinical data were noted at admission and twice a day during follow-up, and laboratory analyses (with troponin testing) were performed. RESULTS: At admission, patients had no or moderate tachycardia (pulse = 82 +/- 27 bpm). Among them, a 32-year-old midwife admitted on her fourth day of symptoms had marked bradycardia: 43 bpm. ECG showed sinus bradycardia with no conduction disturbances or repolarization anomalies; findings were similar for the three other patients with bradycardia (< 60 bpm). During follow-up, her pulse gradually increased, as it did for the other three; all four recovered. DISCUSSION: Despite several factors likely to promote tachycardia, we observed no or only moderate tachycardia in all patients with Ebola. In our study, ECG recorded sinus rhythm, without significant node dysfunction or atrioventricular block. In the absence of any evidence of myocarditis, we discuss the possibility of a central nervous system cause, associated with encephalitis. CONCLUSION: We observed relative or marked bradycardia in our patients infected with Ebola. We hypothesize that its causal mechanism was encephalitis. PMID- 27694086 TI - Proper use of drugs and relation between purchasing power and cost of treatment prescribed in Casamance. AB - In Senegal, health insurance is available only to employees in the private and public sector and to the elderly (through the Sesame program). The rest of the population, especially different categories of vulnerable people, has no health insurance. Their access to healthcare and to medications is thus limited. In this study, we sought to analyze the relation between purchasing power and costs of treatment prescribed in one city. We questioned the customers leaving pharmacies in Ziguinchor, the administrative center of the lower Casamance, in southern Senegal, and analyzed their prescriptions and over-the-counter purchases. In all, we examined 255 prescriptions/purchases including 643 drugs; 29.4% were written by prescribers in the public health sector. The customers with these prescriptions were less educated, had lower incomes, used taxis more often, and consulted nurses more often than customers with prescriptions from the private health sector. Injectables and INN (international nonproprietary names) were dispensed most often to customers with prescriptions. Dispensing was usually better when the drug was prescribed, and when it was prescribed by a doctor. Nurses appeared to be inadequately trained in the proper use of medications. The percentage of drugs purchased did not depend on the patients' financial means or educational level. Those who most often acquired all of the drugs prescribed were those who had consulted a doctor rather than another type of healthcare provider. PMID- 27694088 TI - Detection of the serogoups and serotypes causing bacterial meningitidis in Bangui, 2012. AB - OBJECTIVE: The aim of this study was to identify the serogroup and serotypes causing bacterial meningitidis and to determine their prevalence in Bangui, Central African Republic. MATERIALS AND METHODS: Cerebrospinal fluid (CSF) from patients with suspected meningitis were collected and tested with cell counts, Gram staining, cultures, the latex agglutination test (LAT), and real-time PCR that used specific primers and probes for S. pneumoniae, N. meningitidis, and H. influenzae. Patients were eligible if they had a CSF sample as well as information about cell counts, Gram staining, the culture, the LAT, and the PCR. Antibiotic detection disks from Bio-Rad laboratory were used to test for the presence of antibiotic activity in the CSF. An uncorrected Chi2 test was used for comparisons. RESULTS: Of the 216 CSF samples collected, 71 were analyzed: 17 Gram stains were positive, as were 6 cultures, 15 LATs, and 33 PCRs. Among the latter, the serogroup distribution was highest for S. pneumoniae, which accounted for 82% (27/33) of the positive cases; H. influenzae type b accounted for 12% (4/33), and N. meningitidis A for 6% (2/33) positive cases. N. meningitidis No W135, N. meningitides B, N. meningitides X, or Streptococcus C serogroups were isolated. CONCLUSION: One year after the introduction of the PCV 13 vaccine, S. pneumoniae was identified as the predominant disease-causing strain. This study demonstrated the essential role of laboratory confirmation of meningitis cases to assess changes in disease epidemiology. PMID- 27694087 TI - Efficacy of sulfadoxine-pyrimethamine for the treatment of uncomplicated falciparum malaria in southern Mauritania. AB - BACKGROUND: Until 2006, the Mauritanian Ministry of Health recommended chloroquine and sulfadoxine-pyrimethamine for first- and second-line treatment of uncomplicated malaria, respectively. This study assessed the clinical efficacy of sulfadoxine-pyrimethamine in Kobeni as first-line treatment. MATERIALS AND METHODS: This study included 55 patients with Plasmodium falciparum infections, who were treated with sulfadoxine-pyrimethamine and followed up for 28 days. Isolates were genotyped to distinguish between recrudescence and reinfection. Treatment success rates and survival were analysed per protocol to evaluate drug efficacy. RESULTS: After inclusion, 2 patients were excluded for protocol violations, and 3 patients were lost to follow-up. Of the remaining 50 patients (per protocol population), 43 (86%) had adequate clinical and parasitological responses. Of the 7 patients with treatment failure, 5 (10%) were early failures, while 2 (4%) had initially responded and had late clinical failure on day 7, associated with recrudescence. With the exception of one adult weighing 91 kg, all treatment failures occurred in children aged from 7 to 12 years. CONCLUSIONS: Sulfadoxine-pyrimethamine monotherapy was moderately effective but insufficiently reliable in view of the relatively high rate of early treatment failure. The high prevalence of chloroquine resistance found in earlier studies and the results of the present study on sulfadoxine-pyrimethamine justify the change in national policy and systematic use of artemisinin-based combination therapy for first-line treatment of P. falciparum malaria in Mauritania. PMID- 27694089 TI - Therapeutic patient education and disclosure of status of HIV infected children in Yaounde, Cameroon Achievements and competence. AB - INTRODUCTION: Psychosocial support and therapeutic patient education are recommended practices that are poorly reported. Our objective was to describe the main achievements after a patient therapeutic education program conducted for pre adolescents and adolescents with HIV infection. METHOD: This qualitative study of 37 children with a mean age of 11 years assessed the outcome of an educational program of 8 sessions that ended by the disclosure of their HIV status. Semistructured interviews that took place 8 weeks after the last session and lasted 20 minutes evaluated the following areas: knowledge of the disease, its treatment, its prevention, and their skills in managing their treatment and the secret. RESULTS: The level of knowledge was acceptable except about HIV transmission, and specifically, how they had acquired the disease. In all, 33/37 (89%) of the children were able to cite or write the name of their disease; 29/37 (78%) had acquired knowledge of their treatment (name of the drugs, objective, and daily treatment times); they were able to manage treatment intake away from home; and secrecy was the standard for all. However, many were unable to explain how they had acquired the virus. CONCLUSION: Therapeutic patient education for HIV status disclosure enables adolescents to acquire knowledge about their disease and the ability to manage it. The poor results observed for knowledge of transmission needs to be improved after disclosure in support groups. PMID- 27694090 TI - Malnutrition: prevalence and risk factors among the children younger than five years in a semi-urban area of Abidjan. AB - INTRODUCTION: In Cote d'Ivoire, the prevalence of malnutrition among children younger than 5 years exceeded 5% in 2011 and was thus considered serious. This overall prevalence may nonetheless mask differences and specificities between regions and municipalities. This study sought to determine the prevalence and risk factors of malnutrition among children in this age group in a semi-urban area of Abidjan. METHODS: This exhaustive, descriptive, cross-sectional survey took place from May 6 to July 31, 2010. The children's nutritional status was determined according to the WHO criteria. Univariate and multivariate analysis of factors associated with malnutrition (social and demographic characteristics, immunization status, children's eating practices, and household characteristics) were studied. RESULTS: We visited 668 households and recruited 809 children. The prevalence of malnutrition was 22.5%. Multivariate analysis showed that the introduction of porridge after 6 months halved the risk of malnutrition. Risk tripled for children whose father's occupation did not guarantee a regular income. CONCLUSION: Among the factors highlighted by this study, dietary practices seem the most amenable to corrective action. For example, the adoption of outreach programs by the Maternal and Child Protection services could improve nutritional practices in households. PMID- 27694091 TI - Tuberculosis in children in Togo: epidemiology, diagnosis, treatment, and outcome. AB - INTRODUCTION: Tuberculosis (TB) remains one of the most lethal communicable diseases in the world, according to the World Health Organization (WHO). New strategies must be implemented to meet targets for 2035. OBJECTIVE: Describe the epidemiological and therapeutic aspects of tuberculosis in children in Togo. MATERIALS AND METHODS: This retrospective, multicenter, descriptive cross sectional study examined the files of children younger than 15 years who were diagnosed with TB and treatment in the Maritime region from 2008 to 2011. RESULTS: The study included 74 children aged 0-15 years, for an average of 18 cases of childhood tuberculosis annually. Pulmonary tuberculosis (38 cases) was the most common. TB-HIV co-infection was found in 14.9% of cases. Boys accounted for more than half of the patients. The age range of 11-15 years accounted for the highest proportion of cases (41.9%). The most common treatment was a combination of 2RHZE and 4RH (25 children, 33.8%). Laboratory monitoring was satisfactory. In all, 56 (75.7%) children were cured, and 14 (18.2%) lost to follow-up, while 3 (4%) died (all with TB/HIV). CONCLUSION: Active testing for HIV infection is essential in children with TB, because the combination of the two can be lethal. PMID- 27694092 TI - Tetanus in women of childbearing age in the infectious disease department in the national hospital of Conakry (Guinea). AB - OBJECTIVES: This study aimed to determine the hospital prevalence rate of tetanus in women of childbearing age in the infectious disease department of Donka CHU in Conakry and to describe their sociodemographic characteristics and outcomes. METHODOLOGY: This descriptive retrospective study examined the records of all patients aged 15 to 495 years hospitalized for tetanus over a 10-year period. RESULTS: During the study period, 74555 patients were hospitalized - 239 for tetanus. In all, 22 woman of childbearing age had tetanus, that is, 9.2%. Their mean age was 325 years. Most of the women were married (13/22) and lived in Conakry (18/22); 165 were housewives, and 65 patients had begun but not completed the required vaccinations. The incubation period was >75 days for 165 patients. Tetanus infection resulted from medical procedures for 9 women and trauma for 6. We recorded 125 deaths. The average duration of hospitalization was 215 days. CONCLUSION: Preventing tetanus requires a reinforcement of vaccination drives and especially the implementation of policies for booster reminders. PMID- 27694093 TI - Supply of care and neighborhood types in Libreville. AB - Libreville, capital of the Gabonese Republic takes, is part of the worldwide urban planning movement that has recently reached the emerging nations. In this context of increasing urbanization, the health coverage of the population is an important issue. We conducted a field study of the health facilities of all sectors to collect geographical coordinates to map them in 2014. Overall, we mapped 447 medical facilities. Then, in March 2014 we selected 300 households for an investigation in 3 districts (Nkembo, Nzeng Ayong, and Melen) of Libreville. The objective of the investigation was to collect the households' opinions about the geographical accessibility of these facilities. The results enabled us to map these facilities and showed a gradient. Assessment of the distance between these facilities according to district showed that the central district of Nkembo is closer to them than were the pericentral and peripheral neighborhoods. These results tend to show spatial disparities in the supply of health care. At the same time, the assessment of the geographical distance between these facilities and users' homes varies according to the type of district. These results raise the issue of urban planning and healthcare supply in Libreville. PMID- 27694094 TI - Epidemiological data and forensic aspects of road traffic fatalities in Lome, Togo. AB - We collected 190 forensic records from the only pathology laboratory in Lome, over the period from January 2010 to December 2014. The sex ratio (M/F) was 4.4 and the decedents' average age 33.4 years. In 43.2% of cases, the accident resulted from a collision between a pedestrian and a motorcycle; excess speed noted in 56.8% of cases. Four principal groups of fatal injuries were observed: polytrauma (136 cases), isolated severe head injury (49 cases), isolated thoracic contusion (3 cases), and abdominal pelvic contusion with perinea trauma (2 cases). PMID- 27694095 TI - Anterior uveitis as the first sign of human African trypanosomiasis: a case report. AB - We report the case of a 13-year-old girl who consulted for blurred vision, pain, and redness in her left eye. Ophthalmologic examination revealed chronic, hypertensive, and non-granulomatous anterior uveitis. The disease course was marked by a reversal of diurnal rhythm, with daytime sleepiness and behavioral disorders. A neuropsychiatric examination suggested human African trypanosomiasis (HAT), or sleeping sickness. The diagnosis was confirmed by the detection of Trypanosoma in the cerebrospinal fluid. The NECT regimen (nifurtimox-eflornithine combination therapy) was administered as medical treatment and resulted in the disappearance of all clinical signs. This observation suggests that the diagnosis of HAT can be considered in cases of anterior uveitis in individuals with a history of residence in or travel to an area endemic for it.

AB - BACKGROUND: Large datasets of the audit log of modern physiologic monitoring devices have rarely been used for predictive modeling, capturing unsafe practices, or guiding initiatives on alarm systems safety. OBJECTIVE: This paper (1) describes a large clinical dataset using the audit log of the physiologic monitors, (2) discusses benefits and challenges of using the audit log in identifying the most important alarm signals and improving the safety of clinical alarm systems, and (3) provides suggestions for presenting alarm data and improving the audit log of the physiologic monitors. METHODS: At a 20-bed transplant cardiac intensive care unit, alarm data recorded via the audit log of bedside monitors were retrieved from the server of the central station monitor. RESULTS: Benefits of the audit log are many. They include easily retrievable data at no cost, complete alarm records, easy capture of inconsistent and unsafe practices, and easy identification of bedside monitors missed from a unit change of alarm settings adjustments. Challenges in analyzing the audit log are related to the time-consuming processes of data cleaning and analysis, and limited storage and retrieval capabilities of the monitors. CONCLUSIONS: The audit log is a function of current capabilities of the physiologic monitoring systems, monitor's configuration, and alarm management practices by clinicians. Despite current challenges in data retrieval and analysis, large digitalized clinical datasets hold great promise in performance, safety, and quality improvement. Vendors, clinicians, researchers, and professional organizations should work closely to identify the most useful format and type of clinical data to expand medical devices' log capacity. PMID- 27694098 TI - Prediction of Sepsis in the Intensive Care Unit With Minimal Electronic Health Record Data: A Machine Learning Approach. AB - BACKGROUND: Sepsis is one of the leading causes of mortality in hospitalized patients. Despite this fact, a reliable means of predicting sepsis onset remains elusive. Early and accurate sepsis onset predictions could allow more aggressive and targeted therapy while maintaining antimicrobial stewardship. Existing detection methods suffer from low performance and often require time-consuming laboratory test results. OBJECTIVE: To study and validate a sepsis prediction method, InSight, for the new Sepsis-3 definitions in retrospective data, make predictions using a minimal set of variables from within the electronic health record data, compare the performance of this approach with existing scoring systems, and investigate the effects of data sparsity on InSight performance. METHODS: We apply InSight, a machine learning classification system that uses multivariable combinations of easily obtained patient data (vitals, peripheral capillary oxygen saturation, Glasgow Coma Score, and age), to predict sepsis using the retrospective Multiparameter Intelligent Monitoring in Intensive Care (MIMIC)-III dataset, restricted to intensive care unit (ICU) patients aged 15 years or more. Following the Sepsis-3 definitions of the sepsis syndrome, we compare the classification performance of InSight versus quick sequential organ failure assessment (qSOFA), modified early warning score (MEWS), systemic inflammatory response syndrome (SIRS), simplified acute physiology score (SAPS) II, and sequential organ failure assessment (SOFA) to determine whether or not patients will become septic at a fixed period of time before onset. We also test the robustness of the InSight system to random deletion of individual input observations. RESULTS: In a test dataset with 11.3% sepsis prevalence, InSight produced superior classification performance compared with the alternative scores as measured by area under the receiver operating characteristic curves (AUROC) and area under precision-recall curves (APR). In detection of sepsis onset, InSight attains AUROC = 0.880 (SD 0.006) at onset time and APR = 0.595 (SD 0.016), both of which are superior to the performance attained by SIRS (AUROC: 0.609; APR: 0.160), qSOFA (AUROC: 0.772; APR: 0.277), and MEWS (AUROC: 0.803; APR: 0.327) computed concurrently, as well as SAPS II (AUROC: 0.700; APR: 0.225) and SOFA (AUROC: 0.725; APR: 0.284) computed at admission (P<.001 for all comparisons). Similar results are observed for 1-4 hours preceding sepsis onset. In experiments where approximately 60% of input data are deleted at random, InSight attains an AUROC of 0.781 (SD 0.013) and APR of 0.401 (SD 0.015) at sepsis onset time. Even with 60% of data missing, InSight remains superior to the corresponding SIRS scores (AUROC and APR, P<.001), qSOFA scores (P=.0095; P<.001) and superior to SOFA and SAPS II computed at admission (AUROC and APR, P<.001), where all of these comparison scores (except InSight) are computed without data deletion. CONCLUSIONS: Despite using little more than vitals, InSight is an effective tool for predicting sepsis onset and performs well even with randomly missing data.

AB - BACKGROUND: Quality of life (QoL) questionnaires are desirable for clinical practice but can be time-consuming to administer and interpret, making their widespread adoption difficult. OBJECTIVE: Our aim was to assess the performance of the World Health Organization Quality of Life (WHOQOL)-100 questionnaire as four item banks to facilitate adaptive testing using simulated computer adaptive tests (CATs) for physical, psychological, social, and environmental QoL. METHODS: We used data from the UK WHOQOL-100 questionnaire (N=320) to calibrate item banks using item response theory, which included psychometric assessments of differential item functioning, local dependency, unidimensionality, and reliability. We simulated CATs to assess the number of items administered before prespecified levels of reliability was met. RESULTS: The item banks (40 items) all displayed good model fit (P>.01) and were unidimensional (fewer than 5% of t tests significant), reliable (Person Separation Index>.70), and free from differential item functioning (no significant analysis of variance interaction) or local dependency (residual correlations < +.20). When matched for reliability, the item banks were between 45% and 75% shorter than paper-based WHOQOL measures. Across the four domains, a high standard of reliability (alpha>.90) could be gained with a median of 9 items. CONCLUSIONS: Using CAT, simulated assessments were as reliable as paper-based forms of the WHOQOL with a fraction of the number of items. These properties suggest that these item banks are suitable for computerized adaptive assessment. These item banks have the potential for international development using existing alternative language versions of the WHOQOL items. PMID- 27694104 TI - Regulatory effects of electronic beam irradiation on mir-21/smad7-mediated collagen I synthesis in keloid-derived fibroblasts. AB - Keloid scarring is an abnormal pathological scar characterized by excessive fibro proliferation and extracellular matrix deposition. Electronic beam irradiation is commonly used with surgical removal to control high recurrence rates of keloid scarring; however, the mechanism remains unknown. In this study, we used keloid derived primary fibroblasts (KF) as the cell model, and a dose of 15 Gy energy, followed by quantitative PCR (qPCR), western blotting and gene overexpression/knock down techniques were used to reveal the molecular mechanisms affected by electronic beam irradiation. We found that mir-21 was highly expressed in KF and was downregulated by irradiation. We also showed that smad7 was a direct target of mir-21. Moreover, the expression level of smad7 was low in KF and upregulated by irradiation. We also found that smad7 controls Col-1 synthesis by mediating p38 phosphorylation, and this process was affected by electronic beam irradiation. The regulatory effect of electronic beam irradiation on the expression of mir-21, smad7, p38, p-p38 and Col-1 could be partly restored by mir-21 overexpression achieved by mir-21 mimic transfection. In conclusion, our data demonstrated that mir-21/smad7 regulated Col-1 expression in KF and that electronic beam irradiation was capable of decreasing Col-1 production by modifying mir-21/smad7-mediated p38 activation. This is the first report identifying the effects of electronic beam irradiation on miRNAs, providing a novel strategy to discover the molecular mechanisms of radiotherapy. PMID- 27694105 TI - Establishment of a novel retinoblastoma (Rb) nude mouse model by intravitreal injection of human Rb Y79 cells - comparison of in vivo analysis versus histological follow up. AB - Retinoblastoma (Rb) is the most frequent primary intraocular tumour in children and, if left untreated, can cause death. Preclinical animal models that mimic molecular, genetic, and cellular features of cancers are essential for studying cancer and searching for promising diagnosis and treatment modalities. There are several models described for Rb, but none of them fully meet our requirements. The aim of this study was to create a novel xenograft-nude mouse-model with broad application possibilities, which closely resembles the clinical observations of Rb patients and which could be used to investigate the development and spread of the tumour by using scanning laser ophthalmoscopy/optical coherence tomography (SLO/OCT) as well as histology methods. We injected human retinoblastoma Y79 cells intravitreally in both eyes of immune-deficient nude mice. The incidences of retinoblastoma as well as growth velocity were analysed 3, 6, 9 and 12 weeks after cell injection in vivo by SLO/OCT as well as ex vivo by electron microscopy (EM) and hematoxylin/eosin (HE) staining. Moreover, internal organs were histologically screened for potentially occurring metastases. Three weeks post injection, animals developed a retinoblastoma, and after five weeks tumour growth resulted in swelling of the eyes in individual animals, showing a similar phenotype to that of untreated Rb patients at advanced stages of tumour development. After 12 weeks, 67.5% of all analysed eyes (29 of 42) contained a retinoblastoma. At early stages of Rb development, the SLO/OCT analysis correlated with the histology results. If the tumours were too large, only histological investigations were feasible. The ultrastructural characteristics of the xenograft-tumours were very similar to those described for patient's tumours. In one mouse, brain metastases were observed. Our retinoblastoma mouse model closely resembles the human disease. SLO/OCT can be used for the detection of Rb at early stages of development and could be used for monitoring the success of future therapies. PMID- 27694106 TI - Oviposition preferences for ethanol depend on spatial arrangement and differ dramatically among closely related Drosophila species. AB - Recent work on the model fly Drosophila melanogaster has reported inconsistencies in their preference for laying eggs on intermediate concentrations of ethanol. In this study, we resolve this discrepancy by showing that this species strongly prefers ovipositing on ethanol when it is close to a non-ethanol substrate, but strongly avoids ethanol when options are farther apart. We also show fluidity of these behaviors among other Drosophila species: D. melanogaster is more responsive to ethanol than close relatives in that it prefers ethanol more than other species in the close-proximity case, but avoids ethanol more than other species in the distant case. In the close-proximity scenario, the more ethanol tolerant species generally prefer ethanol more, with the exception of the island endemic D. santomea This species has the lowest tolerance in the clade, but behaves like D. melanogaster We speculate that this could be an adaptation to protect eggs from parasites or predators such as parasitoid wasps, as larvae migrate to non-toxic substrates after hatching. These natural differences among species are an excellent opportunity to study how genes and brains evolve to alter ethanol preferences, and provide an interesting model for genetic variation in preferences in other organisms, including humans. PMID- 27694108 TI - The Burden of Cancer in Asian Americans: A Report of National Mortality Trends by Asian Ethnicity. AB - BACKGROUND: Asian Americans (AA) are the fastest growing U.S. population, and when properly distinguished by their ethnic origins, exhibit substantial heterogeneity in socioeconomic status, health behaviors, and health outcomes. Cancer is the second leading cause of death in the United States, yet trends and current patterns in the mortality burden of cancer among AA ethnic groups have not been documented. METHODS: We report age-adjusted rates, standardized mortality ratios, and modeled trends in cancer-related mortality in the following AA ethnicities: Asian Indians, Chinese, Filipinos, Japanese, Koreans, and Vietnamese, from 2003 to 2011, with non-Hispanic whites (NHW) as the reference population. RESULTS: For most cancer sites, AAs had lower cancer mortality than NHWs; however, mortality patterns were heterogeneous across AA ethnicities. Stomach and liver cancer mortality was very high, particularly among Chinese, Koreans, and Vietnamese, for whom these two cancer types combined accounted for 15% to 25% of cancer deaths, but less than 5% of cancer deaths in NHWs. In AA women, lung cancer was a leading cause of death, but (unlike males and NHW females) rates did not decline over the study period. CONCLUSIONS: Ethnicity specific analyses are critical to understanding the national burden of cancer among the heterogeneous AA population. IMPACT: Our findings highlight the need for disaggregated reporting of cancer statistics in AAs and warrant consideration of tailored screening programs for liver and gastric cancers.

AB - BACKGROUND: Physician communication about human papillomavirus (HPV) vaccine is a key determinant of uptake. To support physician communication, we sought to identify messages that would motivate HPV vaccination. METHODS: From 2014 to 2015, we surveyed national samples of parents of adolescents ages 11 to 17 (n = 1,504) and primary care physicians (n = 776). Parents read motivational messages, selected from nine longer messages developed by the Centers for Disease Control and Prevention and six brief messages developed by the study team. Parents indicated whether each message would persuade them to get HPV vaccine for their adolescents. Physicians read the brief messages and indicated whether they would use them to persuade parents to get HPV vaccine for 11- to 12-year-old children. RESULTS: The highest proportion of parents (65%) and physicians (69%) found this brief message to be persuasive: "I strongly believe in the importance of this cancer-preventing vaccine for [child's name]." Parents disinclined to vaccinate were most receptive to messages with information about HPV infection being common, cancers caused by HPV, and HPV vaccine effectiveness. Parents' endorsement did not vary by race/ethnicity, education, child age, or child sex (all P > 0.05). CONCLUSIONS: Our national surveys of parents and physicians identified messages that could motivate HPV vaccination, even among parents disinclined to vaccinate their children. The lack of difference across demographic subgroups in parental endorsement may suggest that these messages can be used across these subgroups. IMPACT: Our findings support physicians' use of these messages with parents to help motivate uptake of this important cancer preventing vaccine. Cancer Epidemiol Biomarkers Prev; 25(10); 1383-91.

AB - OBJECTIVE: To investigate whether sphericity volume index (SVI), an indicator of left ventricular (LV) remodelling, predicts incident cardiovascular events (coronary heart disease, CHD; all cardiovascular disease, CVD; heart failure, HF; atrial fibrillation, AF) over 10 years of follow-up in a multiethnic population (Multi-Ethnic Study of Atherosclerosis). METHODS: 5004 participants free of known CVD had magnetic resonance imaging (MRI) in 2000-2002. Cine images were analysed to compute, [Formula: see text] equivalent to LV volume/volume of sphere with length of LV as the diameter. The highest (greatest sphericity) and lowest (lowest sphericity) quintiles of SVI were compared against the reference group (2 4 quintiles combined). Risk-factor adjusted hazard's ratio (HR) from Cox regression assessed the predictive performance of SVI at end-diastole (ED) and end-systole (ES) to predict incident outcomes over 10 years in retrospective interpretation of prospective data. RESULTS: At baseline, participants were aged 61+/-10 years; 52% men and 39%/13%/26%/22% Cauc/Chinese/Afr-Amer/Hispanic. Low sphericity was associated with higher Framingham CVD risk, greater coronary calcium score and higher N-terminal pro-brain natriuretic peptide (NT-proBNP); while increased sphericity was associated with higher NT-proBNP and lower ejection fraction. Low sphericity predicted incident CHD (HR: 1.48, 1.55-2.59 at ED) and CVD (HR: 1.82, 1.47-2.27 at ED). However, both low (HR: 1.81, 1.20-2.73 at ES) and high (HR: 2.21, 1.41-3.46 at ES) sphericity predicted incident HF. High sphericity also predicted AF. CONCLUSIONS: In a multiethnic population free of CVD at baseline, lowest sphericity was a predictor of incident CHD, CVD and HF over a 10-year follow-up period. Extreme sphericity was a strong predictor of incident HF and AF. SVI improved risk prediction models beyond established risk factors only for HF, but not for all CVD or CHD. PMID- 27694111 TI - The clinical efficacy and long-term prognostic value of stress echocardiography in octogenarians. AB - INTRODUCTION: Although stress echocardiography (SE) is invaluable in younger populations, its prognostic value may be attenuated in the elderly due to shorter life expectancy and the frequent presence of severe comorbidities. This study sought to evaluate the clinical effectiveness of SE in octogenarians, particularly its prognostic value over clinical variables, in predicting hard events. METHODS: A total of 374 consecutive octogenarians who underwent SE for evaluation of coronary artery disease (CAD) were assessed for feasibility, diagnostic accuracy and safety of the test, and followed up for hard outcomes (all-cause mortality, cardiovascular (CV) deaths and non-fatal myocardial infarction (NFMI)). Cox regression analysis was performed to identify predictors of outcome. RESULTS: Of the 374 tests, 360 (96.3%) were diagnostic. Of the 50 patients with inducible ischaemia, 33 patients (66%) proceeded to angiography of which 27 (82%) patients had significant CAD. During long-term follow-up of 4.0+/ 2.0 years, there were 127 deaths and 36 NFMIs. The annualised mortality, NFMI and combined mortality /NFMI rates were 8.1%, 1.8% and 9.4% for patients with a normal SE and 12.1%, 5.5% and 14.1% for those with an abnormal SE, respectively. Predictors of NFMI on multivariate analysis were prior CAD (HR 2.89, CI 1.03 to 8.15, p=0.045), peripheral vascular disease (HR 3.33, CI 1.18 to 9.45, p=0.02), and inducible ischaemia (HR 3.97, CI 1.49 to 10.55, p=0.006). In patients without prior history of CAD, inducible ischaemia was the only independent predictor of NFMI (HR 8.72, CI 1.46 to 52.2, p=0.018). The larger the extent of ischaemia, the greater the incidence of NFMI. The independent predictors of CV events (NFMI or CV mortality) were PAD (HR 2.81, CI 1.21 to 6.52, p=0.016) and peak wall motion score index (HR 5.71, CI 1.67 to 19.6, p=0.006). Although inducible ischaemia predicted all-cause mortality on unadjusted analysis, it did not on multivariate analysis. CONCLUSIONS: In octogenarians, SE demonstrated excellent feasibility, safety and diagnostic accuracy. SE parameters were independent predictors of NFMI and CV events, and the presence of inducible ischaemia was associated with a 50% increase in all-cause mortality.

AB - Multi-parent populations (MPPs) capture and maintain the genetic diversity from multiple inbred founder strains to provide a resource for high-resolution genetic mapping through the accumulation of recombination events over many generations. Breeding designs that maintain a large effective population size with randomized assignment of breeders at each generation can minimize the impact of selection, inbreeding, and genetic drift on allele frequencies. Small deviations from expected allele frequencies will have little effect on the power and precision of genetic analysis, but a major distortion could result in reduced power and loss of important functional alleles. We detected strong transmission ratio distortion in the Diversity Outbred (DO) mouse population on chromosome 2, caused by meiotic drive favoring transmission of the WSB/EiJ allele at the R2d2 locus. The distorted region harbors thousands of polymorphisms derived from the seven non WSB founder strains and many of these would be lost if the sweep was allowed to continue. To ensure the utility of the DO population to study genetic variation on chromosome 2, we performed an artificial selection against WSB/EiJ alleles at the R2d2 locus. Here, we report that we have purged the WSB/EiJ allele from the drive locus while preserving WSB/EiJ alleles in the flanking regions. We observed minimal disruption to allele frequencies across the rest of the autosomal genome. However, there was a shift in haplotype frequencies of the mitochondrial genome and an increase in the rate of an unusual sex chromosome aneuploidy. The DO population has been restored to genome-wide utility for genetic analysis, but our experience underscores that vigilant monitoring of similar genetic resource populations is needed to ensure their long-term utility. PMID- 27694114 TI - Epigenetic Control of Phenotypic Plasticity in the Filamentous Fungus Neurospora crassa. AB - Phenotypic plasticity is the ability of a genotype to produce different phenotypes under different environmental or developmental conditions. Phenotypic plasticity is a ubiquitous feature of living organisms, and is typically based on variable patterns of gene expression. However, the mechanisms by which gene expression is influenced and regulated during plastic responses are poorly understood in most organisms. While modifications to DNA and histone proteins have been implicated as likely candidates for generating and regulating phenotypic plasticity, specific details of each modification and its mode of operation have remained largely unknown. In this study, we investigated how epigenetic mechanisms affect phenotypic plasticity in the filamentous fungus Neurospora crassa By measuring reaction norms of strains that are deficient in one of several key physiological processes, we show that epigenetic mechanisms play a role in homeostasis and phenotypic plasticity of the fungus across a range of controlled environments. In general, effects on plasticity are specific to an environment and mechanism, indicating that epigenetic regulation is context dependent and is not governed by general plasticity genes. Specifically, we found that, in Neurospora, histone methylation at H3K36 affected plastic response to high temperatures, H3K4 methylation affected plastic response to pH, but H3K27 methylation had no effect. Similarly, DNA methylation had only a small effect in response to sucrose. Histone deacetylation mainly decreased reaction norm elevation, as did genes involved in histone demethylation and acetylation. In contrast, the RNA interference pathway was involved in plastic responses to multiple environments. PMID- 27694117 TI - Radiation-Induced Cerebral Vascular "Malformations" at Biopsy. AB - Radiation-induced vascular "malformations", designated cavernous hemangiomas/cavernomas ("RICHs"), are seldom biopsied and are usually diagnosed based on neuroimaging features. They are an increasingly recognized complication of both CNS external beam radiation therapy and stereotactic radiosurgery. We identified 13 patients with radiation-induced vascular "malformations" in our surgical neuropathology databases searched from 2000 to 2016; 4 had received their therapy during childhood; 5 had received radiosurgery. Inclusion required identifiable vascular abnormalities on neuroimaging and/or, if recurrent tumor was additionally present, the vascular lesion had been a separately submitted specimen at the time of resection. Trichrome, and elastic stains and immunohistochemistry (IHC) for CD31, CD34, and smooth muscle actin (SMA) were performed. Five RICHs showed histological and IHC overlap with 12 non-radiation induced cavernomas; 8/13 had organizing coagulum containing recanalized vasculature and fibrinous deposits. Markedly altered vasculature in these 8 lacked the back-to-back caverns typical of cavernomas; there was near absence of SMA immunopositivity in their ill-defined vessel walls. These coagulum-like lesions likely represented organized fibrinous exudates caused by subacute/remote radiation-induced fibrinoid vascular necrosis and vascular leakage. Thus, RICHs occur as 2 distinct histological types, without direct correlation between histological type and age at receipt, or type, of radiation. Two different etiological mechanisms likely underlie their pathogenesis. PMID- 27694116 TI - Male-Specific Transcription Factor Occupancy Alone Does Not Account for Differential Methylation at Imprinted Genes in the mouse Germ Cell Lineage. AB - Genomic imprinting is an epigenetic mechanism that affects a subset of mammalian genes, resulting in monoallelic expression depending on the parental origin of the alleles. Imprinted regions contain regulatory elements that are methylated in the gametes in a sex-specific manner (differentially methylated regions; DMRs). DMRs are present at nonimprinted loci as well, but whereas most regions are equalized after fertilization, methylation at imprinted regions maintains asymmetry. We tested the hypothesis that paternally unmethylated DMRs are occupied by transcription factors (TFs) present during male gametogenesis. Meta analysis of mouse RNA data to identify DNA-binding proteins expressed in male gametes and motif enrichment analysis of active promoters yielded a list of candidate TFs. We then asked whether imprinted or nonimprinted paternally unmethylated DMRs harbored motifs for these TFs, and found many shared motifs between the two groups. However, DMRs that are methylated in the male germ cells also share motifs with DMRs that remain unmethylated. There are recognition sequences exclusive to the unmethylated DMRs, whether imprinted or not, that correspond with cell-cycle regulators, such as p53. Thus, at least with the current available data, our results indicate a complex scenario in which TF occupancy alone is not likely to play a role in protecting unmethylated DMRs, at least during male gametogenesis. Rather, the epigenetic features of DMRs, regulatory sequences other than DMRs, and the role of DNA-binding proteins capable of endowing sequence specificity to DNA-methylating enzymes are feasible mechanisms and further investigation is needed to answer this question. PMID- 27694115 TI - Regulation of Secondary Metabolism by the Velvet Complex Is Temperature Responsive in Aspergillus. AB - Sensing and responding to environmental cues is critical to the lifestyle of filamentous fungi. How environmental variation influences fungi to produce a wide diversity of ecologically important secondary metabolites (SMs) is not well understood. To address this question, we first examined changes in global gene expression of the opportunistic human pathogen, Aspergillus fumigatus, after exposure to different temperature conditions. We found that 11 of the 37 SM gene clusters in A. fumigatus were expressed at higher levels at 30 degrees than at 37 degrees . We next investigated the role of the light-responsive Velvet complex in environment-dependent gene expression by examining temperature-dependent transcription profiles in the absence of two key members of the Velvet protein complex, VeA and LaeA We found that the 11 temperature-regulated SM gene clusters required VeA at 37 degrees and LaeA at both 30 and 37 degrees for wild-type levels of expression. Interestingly, four SM gene clusters were regulated by VeA at 37 degrees but not at 30 degrees , and two additional ones were regulated by VeA at both temperatures but were substantially less so at 30 degrees , indicating that the role of VeA and, more generally of the Velvet complex, in the regulation of certain SM gene clusters is temperature-dependent. Our findings support the hypothesis that fungal secondary metabolism is regulated by an intertwined network of transcriptional regulators responsive to multiple environmental factors.

AB - Primary care physicians are often the first to see a child with the complaint of eye pain. The eye examination in children is not easy, and the entities that can cause pain in children range from a foreign body in the cornea to the most serious amblyogenic (inducing decreased vision) and life-threatening conditions. Eye pain is a red flag for ocular and systemic conditions, either in a "quiet eye" or "red eye." A detailed history of present illness; pertinent review of systems; close attention to the past medical, family, and social histories; and meticulous physical examination can help to determine the cause, establish the correct treatment, and serve as the basis for referral to a pediatric ophthalmologist if necessary.

AB - BACKGROUND: There is a need for greater guidance regarding design parameters and empirical benchmarks for social and behavioral outcomes to inform assumptions in the design and interpretation of cluster randomized trials (CRTs). OBJECTIVES: We calculated the empirical reference values on critical research design parameters associated with statistical power for children's social and behavioral outcomes, including effect sizes, intraclass correlations (ICCs), and proportions of variance explained by a covariate at different levels (R 2). SUBJECTS: Children from kindergarten to Grade 5 in the samples from four large CRTs evaluating the effectiveness of two classroom- and two school-level preventive interventions. MEASURES: Teacher ratings of students' social and behavioral outcomes using the Teacher Observation of Classroom Adaptation-Checklist and the Social Competence Scale-Teacher. RESEARCH DESIGN: Two types of effect size benchmarks were calculated: (1) normative expectations for change and (2) policy-relevant demographic performance gaps. The ICCs and R 2 were calculated using two-level hierarchical linear modeling (HLM), where students are nested within schools, and three-level HLM, where students were nested within classrooms, and classrooms were nested within schools. RESULTS AND CONCLUSIONS: Comprehensive tables of benchmarks and ICC values are provided to inform prevention researchers in interpreting the effect size of interventions and conduct power analyses for designing CRTs of children's social and behavioral outcomes. The discussion also provides a demonstration for how to use the parameter reference values provided in this article to calculate the sample size for two- and three-level CRTs designs. PMID- 27694128 TI - Reviewing the Reviews: Examining Similarities and Differences Between Federally Funded Evidence Reviews. AB - BACKGROUND: The federal government's emphasis on supporting the implementation of evidence-based programs has fueled a need to conduct and assess rigorous evaluations of programs. Through partnerships with researchers, policy makers, and practitioners, evidence reviews-projects that identify, assess, and summarize existing research in a given area-play an important role in supporting the quality of these evaluations and how the findings are used. These reviews encourage the use of sound scientific principles to identify, select, and implement evidence-based programs. The goals and standards of each review determine its conclusions about whether a given evaluation is of high quality or a program is effective. It can be difficult for decision makers to synthesize the body of evidence when faced with results from multiple program evaluations. SAMPLE: This study examined 14 federally funded evidence reviews to identify commonalities and differences in their assessments of evidence of effectiveness. FINDINGS: There were both similarities and significant differences across the reviews. In general, the evidence reviews agreed on the broad critical elements to consider when assessing evaluation quality, such as research design, low attrition, and baseline equivalence. The similarities suggest that, despite differences in topic and the availability of existing research, reviews typically favor evaluations that limit potential bias in their estimates of program effects. However, the way in which some of the elements were assessed, such as what constituted acceptable amounts of attrition, differed. Further, and more substantially, the reviews showed greater variation in how they conceptualized "effectiveness." PMID- 27694129 TI - Effect of Interstitial Fluid Pressure on Ultrasound Axial Strain and Axial Shear Strain Elastography. AB - Ultrasound elastography is an imaging modality that has been used to diagnose tumors of the breast, thyroid, and prostate. Both axial strain elastography and axial shear strain elastography (ASSE) have shown significant potentials to differentiate between benign and malignant tumors. Elevated interstitial fluid pressure (IFP) is a characteristic of many malignant tumors and a major barrier in targeted drug delivery therapies. This parameter, however, has not received significant attention in ultrasound elastography and, in general, in most diagnostic imaging modalities yet. In this paper, we investigate the effect of an underlying IFP contrast on ultrasound axial strain and axial shear strain imaging using finite element analysis. Our results show that an underlying contrast in IFP creates a new contrast mechanism in both the axial strain and axial shear strain elastographic images. This information might be important for a better interpretation of elastographic images of tumors.

PMID- 27694130 TI - Clinical and Histologic Predictive Factors of Response to Induction Chemotherapy in Head and Neck Squamous Cell Carcinoma. AB - Objectives: Induction chemotherapy (IC) is occasionally used in head and neck cancer, leading to less extensive surgery and reduced need for irradiation. Factors predicting the response to IC have not been determined. In this study, we investigated the clinical and histopathologic factors that predict the response to IC. Methods: Head and neck squamous cell carcinomas from 81 patients were analyzed; clinical factors, histologic parameters, and expression of p16 and p53 were correlated with response to chemotherapy and prognosis. Results: Factors predicting a good response to IC were the nonoropharyngeal localization, a rich lymphocytic tissue response, and a low platelet-to-lymphocyte blood ratio before treatment. Response to IC did not correlate with prognosis, whereas a low neutrophil-to-lymphocyte ratio (NLR), the absence of a desmoplastic reaction, a rich lymphocytic tissue response, and the overexpression of p53 were associated with better prognosis. Conclusions: Lymphocytic tissue response, NLR, and nonoropharyngeal localization are factors predictive of response to IC. PMID- 27694133 TI - ERRATUM.

AB - StAR-related lipid transfer (START) domains are phospholipid- or sterol-binding modules that are present in many proteins. START domain-containing proteins (START proteins) play important functions in eukaryotic cells, including the redistribution of phospholipids to subcellular compartments and delivering sterols to the mitochondrion for steroid synthesis. How the activity of the START domain is regulated remains unknown for most of these proteins. The Plasmodium falciparum START protein PFA0210c (PF3D7_0104200) is a broad-spectrum phospholipid transfer protein that is conserved in all sequenced Plasmodium species and is most closely related to the mammalian START proteins STARD2 and STARD7. PFA0210c is unusual in that it contains a signal sequence and a PEXEL export motif that together mediate transfer of the protein from the parasite to the host erythrocyte. The protein also contains a C-terminal extension, which is very uncommon among mammalian START proteins. Whereas the biochemical properties of PFA0210c have been characterized, the function of the protein remains unknown. Here, we provide evidence that the unusual C-terminal extension negatively regulates phospholipid transfer activity. Furthermore, we use the genetically tractable Plasmodium knowlesi model and recently developed genetic technology in P. falciparum to show that the protein is essential for growth of the parasite during the clinically relevant asexual blood stage life cycle. Finally, we show that the regulation of phospholipid transfer by PFA0210c is required in vivo, and we identify a potential second regulatory domain. These findings provide insight into a novel mechanism of regulation of phospholipid transfer in vivo and may have important implications for the interaction of the malaria parasite with its host cell.

AB - RNA editing of adenosine residues to inosine ('A-to-I editing') is the most common RNA modification event detectible with RNA sequencing (RNA-seq). While not directly detectable, inosine is read by next-generation sequencers as guanine. Therefore, mapping RNA-seq reads to their corresponding reference genome can detect potential editing events by identifying 'A-to-G' conversions. However, one must exercise caution when searching for editing sites, as A-to-G conversions also arise from sequencing errors as well as mutations. To address these complexities, several algorithms and software products have been developed to accurately identify editing events. Here, we survey currently available methods to analyze RNA editing events and introduce a new easy-to-use bioinformatics tool 'RNAEditor' for the detection of RNA editing events. During the development of RNAEditor, we noticed editing often happened in clusters, which we named 'editing islands'. We developed a clustering algorithm to find editing islands and included it in RNAEditor. RNAEditor is freely available at http://rnaeditor.uni frankfurt.de. We anticipate that RNAEditor will provide biologists with an easy to-use tool for studying RNA editing events and the newly defined editing islands. PMID- 27694137 TI - Longitudinal examination of temporality in the association between chronic disease diagnosis and changes in work status and hours worked. AB - OBJECTIVES: To examine the longitudinal relationship between incidence of diagnosed chronic disease and work status and hours worked. METHODS: A dynamic cohort approach was taken to construct our study sample using the Canadian National Population Health Survey. Participant inclusion criteria included being employed and without a chronic health condition in the survey cycle prior to diagnosis, and participation in consecutive surveys following diagnosis. Each respondent was matched with up to 5 respondents without a diagnosed health condition. The direct and indirect associations between chronic disease and work status and hours worked following diagnosis were examined using probit and linear regression path models. Separate models were developed for arthritis, back problems, diabetes, hypertension and heart disease. RESULTS: We identified 799 observations with a diagnosis of arthritis, 858 with back pain, 178 with diabetes, 569 with hypertension and 163 with heart disease, which met our selection criteria. An examination of total effects at time 1 and time 2 showed that, excluding hypertension, chronic disease diagnosis was related to work loss. The time 2 effect of chronic disease diagnosis on work loss was mediated through time 1 work status. With the exception of heart disease, an incident case of chronic disease was not related to changes in work hours among observations with continuous work participation. CONCLUSIONS: Chronic disease can result in work loss following diagnosis. Research is required to understand how modifying occupational conditions may benefit employment immediately after diagnosis. PMID- 27694138 TI - Comparative Characterization of Biomechanical Behavior and Healing Profile of a Novel Ultra-High-Molecular-Weight Amorphous Poly-l-Lactic Acid Sirolimus-Eluting Bioresorbable Coronary Scaffold. AB - BACKGROUND: Clinically available bioresorbable scaffolds (BRS) rely on polymer crystallinity to achieve mechanical strength resulting in limited overexpansion capabilities and structural integrity when exposed to high-loading conditions. We aimed to evaluate the biomechanical behavior and vascular healing profile of a novel, sirolimus-eluting, high-molecular-weight, amorphous poly-l-lactic acid based BRS (Amaranth BRS). METHODS AND RESULTS: In vitro biomechanical testing was performed under static and cyclic conditions. A total of 99 devices (65 Amaranth BRS versus 34 Absorb bioresorbable vascular scaffold [BVS]) were implanted in 99 coronary arteries of 37 swine for pharmacokinetics and healing evaluation at various time points. In the Absorb BVS, the number of fractures per scaffold seen on light microscopy was 6.0 (5.0-10.5) when overexpanded 1.0 mm above nominal values (~34%). No fractures were observed in the Amaranth BRS group at 1.3 mm above nominal values (~48% overexpansion). The number of fractures was higher in the Absorb BVS on accelerated cycle testing over time (at 24K cycles=5.0 [5.0 9.0] Absorb BVS versus 0.0 [0.0-0.5] Amaranth BRS). Approximately 90% of sirolimus was found to be eluted by 90 days. Optical coherence tomography analysis demonstrated lower percentages of late scaffold recoil in the Amaranth BRS at 3 months (Amaranth BRS=-10+/-16.1% versus Absorb BVS=10.7+/-13.2%; P=0.004). Histopathology analysis revealed comparable levels of vascular healing and inflammatory responses between both BRSs up to 6 months. CONCLUSIONS: New generation high-molecular-weight amorphous poly-l-lactic acid scaffolds have the potential to improve the clinical performance of BRS and provide the ideal platform for the future miniaturization of the technology. PMID- 27694139 TI - Mindfulness and headache: A "new" old treatment, with new findings. AB - Background Mindfulness refers to a host of procedures that have been practiced for centuries, but only recently have begun to be applied to varied pain conditions, with the most recent being headache. Methods We reviewed research that incorporated components of mindfulness for treating pain, with a more in depth focus on headache disorders. We also examined literature that has closely studied potential physiological processes in the brain that might mediate the effects of mindfulness. We report as well preliminary findings of our ongoing trial comparing mindfulness alone to pharmacological treatment alone for treating chronic migraine accompanied by medication overuse. Results Although research remains in its infancy, the initial findings support the utility of varied mindfulness approaches for enhancing usual care for headache management. Our preliminary findings suggest mindfulness by itself may produce effects comparable to that of medication alone for patients with chronic migraine and medication overuse. Conclusions Much work remains to more fully document the role and long term value of mindfulness for specific headache types. Areas in need of further investigation are discussed. PMID- 27694140 TI - Silencing of SRA1 Regulates ER Expression and Attenuates the Growth of Stromal Cells in Ovarian Endometriosis. AB - Estradiol and its nuclear receptors, estrogen receptor (ER) alpha and ER-beta, have important functions in endometriosis, and the transcriptional activity of these receptors is modulated by coactivators and corepressors. The steroid receptor RNA activator 1 (SRA1) produces SRA long noncoding RNA (lncRNA) and SRA protein (SRAP), which regulate ER expression at the RNA and protein levels in some hormone-dependent tumors via an alternative splicing event. However, only a few are reported on their expressions in endometriosis. Here, we observed that low expression levels of SRA lncRNA and ER-alpha but relatively high expression levels of SRAP and ER-beta were detected in ovarian endometriotic tissues versus normal endometrial tissues. Steroid receptor RNA activator 1-small interfering RNA treatment significantly increased ER-alpha levels but reduced ER-beta levels in endometriotic stromal cells (ESCs). Furthermore, the treatment can also attenuate the proliferation and promote early apoptosis in these cells. Our results indicate that the regulation of ER via SRA in ovarian endometriosis may play a significant role in the growth of ESCs. PMID- 27694141 TI - Hypoxia-inducible factor-2alpha plays a role in mediating oesophagitis in GORD. AB - OBJECTIVE: In an earlier study wherein we induced acute reflux by interrupting proton pump inhibitor (PPI) therapy in patients with reflux oesophagitis (RO) healed by PPIs, we refuted the traditional concept that RO develops as an acid burn. The present study explored our alternative hypothesis that RO results from reflux-stimulated production of pro-inflammatory molecules mediated by hypoxia inducible factors (HIFs). DESIGN: Using oesophageal biopsies taken from patients in our earlier study at baseline and at 1 and 2 weeks off PPIs, we immunostained for HIF-1alpha, HIF-2alpha and phospho-p65, and measured pro-inflammatory molecule mRNAs. We exposed human oesophageal squamous cell lines to acidic bile salts, and evaluated effects on HIF activation, p65 function, pro-inflammatory molecule production and immune cell migration. RESULTS: In patient biopsies, increased immunostaining for HIF-2alpha and phospho-p65, and increased pro inflammatory molecule mRNA levels were seen when RO redeveloped 1 or 2 weeks after stopping PPIs. In oesophageal cells, exposure to acidic bile salts increased intracellular reactive oxygen species, which decreased prolyl hydroxylase function and stabilised HIF-2alpha, causing a p65-dependent increase in pro-inflammatory molecules; conditioned media from these cells increased T cell migration rates. HIF-2alpha inhibition by small hairpin RNA or selective small molecule antagonist blocked the increases in pro-inflammatory molecule expression and T cell migration induced by acidic bile salts. CONCLUSIONS: In patients developing RO, increases in oesophageal HIF-2alpha correlate with increased pro-inflammatory molecule expression. In oesophageal epithelial cells, acidic bile salts stabilise HIF-2alpha, which mediates expression of pro inflammatory molecules. HIF-2alpha appears to have a role in RO pathogenesis. TRIAL REGISTRATION NUMBER: NCT01733810; Results. PMID- 27694143 TI - Prevention of progression from small to large varices: are we there yet? An updated meta-analysis. PMID- 27694142 TI - Uncoupling of mucosal gene regulation, mRNA splicing and adherent microbiota signatures in inflammatory bowel disease. AB - OBJECTIVE: An inadequate host response to the intestinal microbiota likely contributes to the manifestation and progression of human inflammatory bowel disease (IBD). However, molecular approaches to unravelling the nature of the defective crosstalk and its consequences for intestinal metabolic and immunological networks are lacking. We assessed the mucosal transcript levels, splicing architecture and mucosa-attached microbial communities of patients with IBD to obtain a comprehensive view of the underlying, hitherto poorly characterised interactions, and how these are altered in IBD. DESIGN: Mucosal biopsies from Crohn's disease and patients with UC, disease controls and healthy individuals (n=63) were subjected to microbiome, transcriptome and splicing analysis, employing next-generation sequencing. The three data levels were integrated by different bioinformatic approaches, including systems biology inspired network and pathway analysis. RESULTS: Microbiota, host transcript levels and host splicing patterns were influenced most strongly by tissue differences, followed by the effect of inflammation. Both factors point towards a substantial disease-related alteration of metabolic processes. We also observed a strong enrichment of splicing events in inflamed tissues, accompanied by an alteration of the mucosa-attached bacterial taxa. Finally, we noted a striking uncoupling of the three molecular entities when moving from healthy individuals via disease controls to patients with IBD. CONCLUSIONS: Our results provide strong evidence that the interplay between microbiome and host transcriptome, which normally characterises a state of intestinal homeostasis, is drastically perturbed in Crohn's disease and UC. Consequently, integrating multiple OMICs levels appears to be a promising approach to further disentangle the complexity of IBD. PMID- 27694145 TI - A Borrelia afzelii Infection Increases Larval Tick Burden on Myodes glareolus (Rodentia: Cricetidae) and Nymphal Body Weight of Ixodes ricinus (Acari: Ixodidae). AB - Several microorganisms have been shown to manipulate their host or vector to enhance their own transmission. Here we examined whether an infection with Borrelia afzelii affects its transmission between its bank vole (Myodes glareolus, Schreber, 1780) host and tick vector. Captive-bred bank voles were inoculated with B. afzelii or control medium, after which host preference of Ixodes ricinus L. nymphs was determined in a Y-tube olfactometer. Thereafter, infected and uninfected bank voles were placed in a semifield arena containing questing larvae to measure larval tick attachment. Engorged larvae were collected from these bank voles, molted into nymphs, weighed, and analyzed for infection by PCR.Nymphs were attracted to the odors of a bank vole compared to ambient air and preferred the odors of an infected bank vole over that of an uninfected bank vole. In the semifield arena, infected male bank voles had greater larval tick burdens then uninfected males, while similar larval tick burdens were observed on females regardless of infection status. Nymphal ticks that acquired a B. afzelii infection had higher body weight than nymphs that did not acquire an infection regardless of the infection status of the vole. These results show that a B. afzelii infection in bank voles increases larval tick burden and that a B. afzelii infection in larvae increases nymphal body weight. This finding provides novel ecological insights into the enzootic cycle of B. afzelii. PMID- 27694147 TI - A Comparison of Pain Beliefs and Coping Strategies and Their Association with Chronic Pain Adjustment Between Singapore and United States. AB - Objectives: Research examining the importance of pain beliefs and coping strategies to chronic pain adjustment has been performed almost exclusively using Western populations. The purpose of this study was to examine empirically the generalizability of this research to Singapore. Methods: Employing a cross sectional design, measures assessing pain beliefs, coping strategies, pain intensity, pain interference, and depressive symptoms were administered to 101 patients with chronic pain from Singapore. Analyses examined the means of belief and coping strategies measures and their associations with measures of pain intensity, pain interference, and depressive symptoms and compared the results with the data of a sample of 100 patients with chronic pain from a previously published study from the United States. Results: Mean differences between the Singapore and US samples were found for four of the seven belief scales, and four of the eight coping scales. When significant, associations between belief and coping strategies with measures of pain and dysfunction were in the hypothesized directions in both samples. We also found that the strength of four out of 30 of the associations between beliefs/coping strategies and measures of pain and dysfunction were different between the Singapore and US samples. Conclusion: The findings provide further support for the potential influence of culture on how individuals view and cope with pain. However, the many similarities found in direction and strength of the associations between beliefs/coping strategies and measures of pain/dysfunction provide preliminary support for the appropriateness of the use of cognitive behavioral therapy developed in the United States with the Singapore population. PMID- 27694148 TI - Role of Magnetic Resonance Imaging in Ascertaining the Success of Transforaminal Epidural Steroid Injection for Lumbar Radicular Pain. AB - Objective: To explore the outcome differences of lumbar transforaminal epidural steroid injection (TFESI) according to magnetic resonance imaging (MRI) findings in patients with lumbar radicular pain. Design: Retrospective study. Setting: Single university-based interventional pain management unit. Patients: Fifty-nine patients who had lumbar radicular pain with a recent lumbar MRI and three-month follow-up were included. Methods: MRI findings were reviewed for the following items: herniation type (bulging, protrusion, extrusion), herniation location (central, subarticular, foraminal, extraforaminal), high intensity zone (HIZ), and nerve root impingement (NRI). Pain severity was evaluated using a visual analogue scale (VAS) at time of before injection, then two weeks and three months after. Results: Pain scores improved significantly in each group ( P < 0.05) at all time points, but there were no statistically significant differences in improvements according to type or location of disc herniation. Pain scores were significantly lower in patients with HIZ at the second week and in patients with NRI at the third month ( P < 0.05). Conclusions: TFESI was an effective treatment method in patients with radicular pain, irrespective of the type or location of disc herniation. However, greater improvement in pain may be expected at the second week in patients with HIZ and at the third month in patients with NRI. PMID- 27694149 TI - Self-Reported Presence and Experience of Pain in Adults with Down Syndrome. AB - Objective: The aim was to examine whether the presence of pain (based on physical conditions and participants' report) and self-reported pain experience in adults with Down syndrome (DS) differ from general population controls. Design: Cross sectional study of 224 adults with DS (mean age = 38.1 years, mild-severe intellectual disabilities) and 142 age-matched controls (median age = 40.5 years, mean estimated IQ = 105.7) in the Netherlands. Methods: File-based medical information was evaluated. Self-reported presence and experience of pain were assessed in rest and after movement during a test session (affect with facial affective scale (FAS: 0.04-0.97), intensity assessed with numeric rating scale (NRS: 0-10). Results: Compared with controls, more DS participants had physical conditions that may cause pain and/or discomfort ( p = .004, 50% vs 35%), but fewer DS participants reported pain during the test session ( p = .003, 58% vs 73%). Of the participants who indicated pain and comprehended self-reporting scales ( n = 198 FAS, n = 161 NRS), the DS group reported a higher pain affect and intensity than the controls ( p < .001, FAS: 0.75-0.85 vs 0.50-0.59, NRS: 6.00-7.94 vs 2.00-3.73). Conclusions: Not all adults with DS and painful/discomforting physical conditions reported pain. Those who did indicated a higher pain experience than adults from the general population. Research into spontaneous self-report of pain, repeated pain assessment, and acute pain is needed in people with DS for more insight into pain experience and mismatches between self-report and medical information. PMID- 27694150 TI - The Cost of Serious Patient Fall-Related Injuries at Hospitals in Turkey: A Matched Case-Control Study. AB - Patient falls cause economic loss in hospitals, as well as patient injuries. This study aimed to calculate the additional hospital cost and length of stay (LOS) due to fall-related serious injuries and to identify the determining factors for both outcomes. A matched case-control design was used in the study. It was conducted with a case group of 39 patients and a control group of 39 patients in 28 hospitals in Izmir, Turkey. The additional hospital cost and LOS due to fall related serious injuries were calculated to be US$3,302.60 and 14.61 days, respectively. Precautionary initiatives for the injurious falls can prevent patients from getting injured and avoid increases in cost and LOS due to these injuries. PMID- 27694153 TI - Effect of Residual Bacteria on the Outcome of Pulp Regeneration In Vivo. AB - It is not known to what extent residual infection may interfere with the success of pulp regeneration procedures. The aim of this study was to determine, radiographically and histologically, the effect of residual bacteria on the outcome of pulp regeneration mediated by a tissue-engineered construct as compared with traditional revascularization. Periapical lesions were induced in 24 canine teeth of 6 ferrets. After disinfection with 1.25% NaOCl and triple antibiotic paste, ferret dental pulp stem cells, encapsulated in a hydrogel scaffold, were injected into half the experimental teeth. The other half were treated with the traditional revascularization protocol with a blood clot scaffold. After 3 mo, block sections of the canine teeth were imaged radiographically and processed for histologic and histobacteriologic analyses. Associations between variables of interest were evaluated through mixed effects regression models. There were no significant differences between the 2 experimental groups in radiographic root development ( P > 0.05). There was a significant association between the presence of persistent periapical radiolucency and root wall thickness ( P = 0.02). There was also no significant difference in histologic findings between the 2 experimental groups ( P > 0.05). The presence of residual bacteria was significantly associated with lack of radiographic growth ( P < 0.001). The amount of dentin-associated mineralized tissue formed in teeth with residual bacteria was significantly less than in teeth with no residual bacteria ( P < 0.001). Residual bacteria have a critical negative effect on the outcome of regenerative endodontic procedures. PMID- 27694151 TI - Anterior Shoulder Instability in the Military Athlete. AB - CONTEXT: Given its young, predominately male demographics and intense physical demands, the US military remains an ideal cohort for the study of anterior shoulder instability. EVIDENCE ACQUISITION: A literature search of PubMed, MEDLINE, and the Cochrane Database was performed to identify all peer-reviewed publications from 1950 to 2016 from US military orthopaedic surgeons focusing on the management of anterior shoulder instability. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 4. RESULTS: The incidence of anterior shoulder instability events in the military occurs at an order of magnitude greater than in civilian populations, with rates as high as 3% per year among high-risk groups. With more than 90% risk of a Bankart lesion and high risk for instability recurrence, the military has advocated for early intervention of first-time shoulder instability while documenting up to 76% relative risk reduction versus nonoperative treatment. Preoperative evaluation with advanced radiographic imaging should be used to evaluate for attritional bone loss or "off-track" engaging defects to guide comprehensive surgical management. With complex recurrent shoulder instability and/or cases of clinically significant osseous lesions, potential options such as remplissage, anterior open capsular procedures, or bone augmentation procedures may be preferentially considered. CONCLUSION: Careful risk stratification, clinical evaluation, and selective surgical management for at-risk military patients with anterior shoulder instability can optimize the recurrence risk and functional outcome in this population. PMID- 27694154 TI - Extracellular ATP Induces Calcium Signaling in Odontoblasts. AB - Odontoblasts form dentin at the outermost surface of tooth pulp. An increasing level of evidence in recent years, along with their locational advantage, implicates odontoblasts as a secondary role as sensory or immune cells. Extracellular adenosine triphosphate (ATP) is a well-characterized signaling molecule in the neuronal and immune systems, and its potential involvement in interodontoblast communications was recently demonstrated. In an effort to elaborate the ATP-mediated signaling pathway in odontoblasts, the current study performed single-cell reverse transcription polymerase chain reaction (RT-PCR) and immunofluorescent detection to investigate the expression of ATP receptors related to calcium signal in odontoblasts from incisal teeth of 8- to 10-wk-old rats, and demonstrated an in vitro response to ATP application via calcium imaging experiments. While whole tissue RT-PCR analysis detected P2Y2, P2Y4, and all 7 subtypes (P2X1 to P2X7) in tooth pulp, single-cell RT-PCR analysis of acutely isolated rat odontoblasts revealed P2Y2, P2Y4, P2X2, P2X4, P2X6, and P2X7 expression in only a subset (23% to 47%) of cells tested, with no evidence for P2X1, P2X3, and P2X5 expression. An increase of intracellular Ca2+ concentration in response to 100MUM ATP, which was repeated after pretreatment of thapsigargin or under the Ca2+-free condition, suggested function of both ionotropic and metabotropic ATP receptors in odontoblasts. The enhancement of ATP-induced calcium response by ivermectin and inhibition by 5-(3-bromophenyl)-1,3-dihydro-2H benzofuro[3,2-e]-1,4-diazepin-2-one (5-BDBD) confirmed a functional P2X4 subtype in odontoblasts. Positive calcium response to 2',3'-O-(benzoyl-4-benzoyl)-ATP (BzATP) and negative response to alpha,beta-methylene ATP suggested P2X2, P2X4, and P2X7 as functional subunits in rat odontoblasts. Single-cell RT-PCR analysis of the cells with confirmed calcium response and immunofluorescent detection further corroborated the expression of P2X4 and P2X7 in odontoblasts. Overall, this study demonstrated heterogeneous expression of calcium-related ATP receptor subtypes in subsets of individual odontoblasts, suggesting extracellular ATP as a potential signal mediator for odontoblastic functions. PMID- 27694152 TI - TDP-43 stage, mixed pathologies, and clinical Alzheimer's-type dementia. AB - Hyperphosphorylated transactive response DNA-binding protein 43 (TDP-43, encoded by TARDBP ) proteinopathy has recently been described in ageing and in association with cognitive impairment, especially in the context of Alzheimer's disease pathology. To explore the role of mixed Alzheimer's disease and TDP-43 pathologies in clinical Alzheimer's-type dementia, we performed a comprehensive investigation of TDP-43, mixed pathologies, and clinical Alzheimer's-type dementia in a large cohort of community-dwelling older subjects. We tested the hypotheses that TDP-43 with Alzheimer's disease pathology is a common mixed pathology; is related to increased likelihood of expressing clinical Alzheimer's type dementia; and that TDP-43 pathologic stage is an important determinant of clinical Alzheimer's-type dementia. Data came from 946 older adults with ( n = 398) and without dementia ( n = 548) from the Rush Memory and Aging Project and Religious Orders Study. TDP-43 proteinopathy (cytoplasmic inclusions) was present in 496 (52%) subjects, and the pattern of deposition was classified as stage 0 (none; 48%), stage 1 (amygdala; 18%), stage 2 (extension to hippocampus/entorhinal; 21%), or stage 3 (extension to neocortex; 14%). TDP-43 pathology combined with a pathologic diagnosis of Alzheimer's disease was a common mixed pathology (37% of all participants), and the proportion of subjects with clinical Alzheimer's-type dementia formerly labelled 'pure pathologic diagnosis of Alzheimer's disease' was halved when TDP-43 was considered. In logistic regression models adjusted for age, sex, and education, TDP-43 pathology was associated with clinical Alzheimer's-type dementia (odds ratio = 1.51, 95% confidence interval = 1.11, 2.05) independent of pathological Alzheimer's disease (odds ratio = 4.30, 95% confidence interval = 3.08, 6.01) or other pathologies (infarcts, arteriolosclerosis, Lewy bodies, and hippocampal sclerosis). Mixed Alzheimer's disease and TDP-43 pathologies were associated with higher odds of clinical Alzheimer's-type dementia (odds ratio = 6.73, 95% confidence interval = 4.18, 10.85) than pathologic Alzheimer's disease alone (odds ratio = 4.62, 95% confidence interval = 2.84, 7.52). In models examining TDP-43 stage, a dose response relationship with clinical Alzheimer's-type dementia was observed, and a significant association was observed starting at stage 2, extension beyond the amygdala. In this large sample from almost 1000 community participants, we observed that TDP-43 proteinopathy was very common, frequently mixed with pathological Alzheimer's disease, and associated with a higher likelihood of the clinical expression of clinical Alzheimer's-type dementia but only when extended beyond the amygdala. PMID- 27694155 TI - DRN and TRAMP degrade specific and overlapping aberrant mRNAs formed at various stages of mRNP biogenesis in Saccharomyces cerevisiae. AB - In Saccharomyces cerevisiae, nuclear exosome along with TRAMP and DRN selectively eliminates diverse aberrant messages. These decay apparatuses appear to operate as independent mechanisms in the nucleus. Here, using genetic and molecular approach we systematically investigate the functional relationship between exosome, TRAMP and DRN mechanisms by examining their relative contributions in the degradation of diverse classes of aberrant nuclear mRNAs generated at various phases of mRNP biogenesis. Our findings suggest that nuclear exosome in association with the TRAMP complex exclusively degrades the transcription assembly-defective mRNPs and splice-defective intron-containing pre-mRNAs, whereas nuclear exosome along with DRN solely degrades the export-defective messages. The degradation of aberrant read-through transcripts with 3' extensions, in contrast, requires the activity of TRAMP and DRN together along with nuclear exosome function. Thus, the profile of substrate specificity of these nuclear decay machines reflects dependency of the nuclear exosome for either TRAMP or DRN function to degrade distinct nuclear mRNAs. We propose that DRN apparatus may act as a novel ancillary factor required for the nuclear exosome function to degrade specific classes of aberrant messages. PMID- 27694156 TI - eIF4G-an integrator of mRNA metabolism? AB - The eukaryotic translation initiation factor, eIF4G, plays a key functional role in the initiation of cap-dependent translation by acting as an adapter to nucleate the assembly of eIF4F complex. Together with poly(A)-binding protein and eIF3, eIF4F subsequently triggers the recruitment of 43S ribosomal pre-initiation complex to the messenger RNA template. Since eukaryotes primarily regulate translation at the level of initiation, eIF4G is implicated in the control of eukaryotic gene expression. Remarkably, emerging evidence in Saccharomyces cerevisiae indicates that eIF4G also plays a key role in nuclear mRNA biogenesis and surveillance-a finding that is in agreement with its nuclear distribution. Here, we focus on the functional involvement of eIF4G in the nucleus in modulating pre-mRNA splicing, mRNA surveillance and possibly in much-debated nuclear translation. Notably, the nature of the biochemical role of this protein in the major events of cellular mRNA metabolism emphasizes that this crucial protein factor may serve as a general integrator of mRNA functional states by acting as an adapter molecule. PMID- 27694157 TI - A Randomized Phase II Study of Linsitinib (OSI-906) Versus Topotecan in Patients With Relapsed Small-Cell Lung Cancer. AB - LESSONS LEARNED: Targeted therapy options for SCLC patients are limited; no agent, thus far, has resulted in a strategy promising enough to progress to phase III trials.Linsitinib, a potent insulin growth factor-1-receptor tyrosine kinase inhibitor, may be one agent with activity against SCLC.Despite lack of a reliable predictive biomarker in this disease, which may have partly contributed to the negative outcome reported here, linsitinib, although safe, showed no clinical activity in unselected, relapsed SCLC patients. BACKGROUND: Treatment of relapsed small-cell lung cancer (SCLC) remains suboptimal. Insulin growth factor-1 receptor (IGF-1R) signaling plays a role in growth, survival, and chemoresistance in SCLC. Linsitinib is a potent IGF-1R tyrosine kinase inhibitor that potentially may be active against SCLC. METHODS: In this phase II study, 8 eligible patients were randomly assigned in a 1:2 ratio to topotecan (1.5 mg/m2 intravenously or 2.3 mg/m2 orally, daily for 5 days for 4 cycles) or linsitinib (150 mg orally twice daily until progression). The primary endpoint was progression-free survival. Patients with relapsed SCLC, platinum sensitive or resistant, performance status (PS) 0-2, and adequate hematologic, renal, and hepatic function were enrolled. Patients with diabetes, cirrhosis, and those taking insulinotropic agents were excluded. Crossover to linsitinib was allowed at progression. RESULTS: Fifteen patients received topotecan (8 resistant, 3 with PS 2) and 29 received linsitinib (16 resistant, 5 with PS 2). Two partial responses were observed with topotecan. Only 4 of 15 patients with topotecan and 1 of 29 with linsitinib achieved stable disease. Median progression-free survival was 3.0 (95% confidence interval [CI], 1.5-3.6) and 1.2 (95% CI, 1.1-1.4) months for topotecan and linsitinib, respectively (p = .0001). Median survival was 5.3 (95% CI, 2.2-7.6) and 3.4 (95% CI, 1.8-5.6) months for topotecan and linsitinib, respectively (p = .71). Grade 3/4 adverse events (>5% incidence) included anemia, thrombocytopenia, neutropenia/leukopenia, diarrhea, fatigue, dehydration, and hypokalemia for topotecan; and thrombocytopenia, fatigue, and alanine aminotransferase/aspartate aminotransferase elevations for linsitinib. CONCLUSION: Linsitinib was safe but showed no clinical activity in unselected, relapsed SCLC patients. PMID- 27694158 TI - MSF urges world leaders to act over bombing of hospitals in Aleppo.

AB - Background: Research on Roma health is fragmentary as major methodological obstacles often exist. Reliable estimates on vaccination coverage of Roma children at a national level and identification of risk factors for low coverage could play an instrumental role in developing evidence-based policies to promote vaccination in this marginalized population group. Methods: We carried out a national vaccination coverage survey of Roma children. Thirty Roma settlements, stratified by geographical region and settlement type, were included; 7-10 children aged 24-77 months were selected from each settlement using systematic sampling. Information on children's vaccination coverage was collected from multiple sources. In the analysis we applied weights for each stratum, identified through a consensus process. Results: A total of 251 Roma children participated in the study. A vaccination document was presented for the large majority (86%). We found very low vaccination coverage for all vaccines. In 35-39% of children 'minimum vaccination' (DTP3 and IPV2 and MMR1) was administered, while 34-38% had received HepB3 and 31-35% Hib3; no child was vaccinated against tuberculosis in the first year of life. Better living conditions and primary care services close to Roma settlements were associated with higher vaccination indices. Conclusions: Our study showed inadequate vaccination coverage of Roma children in Greece, much lower than that of the non-minority child population. This serious public health challenge should be systematically addressed, or, amid continuing economic recession, the gap may widen. Valid national estimates on important characteristics of the Roma population can contribute to planning inclusion policies. PMID- 27694160 TI - Cost analysis of a peer support programme for patients with type 2 diabetes: a secondary analysis of a controlled trial. AB - Background: This study aimed to explore if group-based peer support as an additional component to a disease management programme (DMP) in type 2 diabetes can reduce the number of prescribed drugs; hospital admissions; and length of hospital stay and therefore be a cost-effective model. Methods: Controlled study based on a secondary data analysis of a cluster randomized trial. Our study population was general practitioners and patients in the province of Salzburg. The 24-months intervention consisted of regular group meetings facilitated by trained peer supporters. The groups exercised together, discussed diabetes related topics, and received support by professionals. Data was anonymously collected on clusters through the statutory health insurance. Results: Data were available of 118 (82.5%,17 clusters of the patients in the original randomized trial) participants in the intervention and 143 (77.3%,19 clusters) in the control groups. The length of hospital stay was shorter in the intervention groups compared with controls. The mean difference during the 24-month study period was -40.13 days (95% CI - 78.54 to - 1.71, P = 0.041) in favour of the intervention groups. No differences were seen in the number of prescribed drugs and hospital admission. Estimated yearly savings by reducing the length of hospital stay was ?1660.60 per patient. Conclusion: A group-based peer support programme as an additional component of a DMP in type 2 diabetes is a promising approach to optimize diabetes care and to enhance lifestyle interventions in primary care. Peer support seems to reduce length of hospital stay and could therefore be a cost-effective model. PMID- 27694162 TI - Prostate Cancer Imaging and Therapy: Potential Role of Nanoparticles. AB - Over the last 2 decades, the use of nanoparticle imaging has been investigated extensively for both diagnosis and therapy of prostate cancer. This review discusses the various classes of nanoparticles currently in clinical use or at the advanced preclinical stage. In particular, we focus on the unique properties of nanoparticles, as a group, that make them suitable for imaging and therapy. The characteristics of each nanoparticle are detailed. Iron oxide nanoparticles, extensively used for MRI of prostate cancer, are discussed in depth. PMID- 27694161 TI - EGF Receptor Inhibition by Erlotinib Increases Aquaporin 2-Mediated Renal Water Reabsorption. AB - Nephrogenic diabetes insipidus (NDI) is caused by impairment of vasopressin (VP) receptor type 2 signaling. Because potential therapies for NDI that target the canonical VP/cAMP/protein kinase A pathway have so far proven ineffective, alternative strategies for modulating aquaporin 2 (AQP2) trafficking have been sought. Successful identification of compounds by our high-throughput chemical screening assay prompted us to determine whether EGF receptor (EGFR) inhibitors stimulate AQP2 trafficking and reduce urine output. Erlotinib, a selective EGFR inhibitor, enhanced AQP2 apical membrane expression in collecting duct principal cells and reduced urine volume by 45% after 5 days of treatment in mice with lithium-induced NDI. Similar to VP, erlotinib increased exocytosis and decreased endocytosis in LLC-PK1 cells, resulting in a significant increase in AQP2 membrane accumulation. Erlotinib increased phosphorylation of AQP2 at Ser-256 and Ser-269 and decreased phosphorylation at Ser-261 in a dose-dependent manner. However, unlike VP, the effect of erlotinib was independent of cAMP, cGMP, and protein kinase A. Conversely, EGF reduced VP-induced AQP2 Ser-256 phosphorylation, suggesting crosstalk between VP and EGF in AQP2 trafficking and a role of EGF in water homeostasis. These results reveal a novel pathway that contributes to the regulation of AQP2-mediated water reabsorption and suggest new potential therapeutic strategies for NDI treatment. PMID- 27694163 TI - Evaluation of Prostate Cancer with PET/MRI. AB - In the ongoing effort to understand and cure prostate cancer, imaging modalities are constantly evolving to assist in clinical decisions. Multiparametric MRI can be used to direct prostate biopsies, improve diagnostic yield, and help clinicians make more accurate decisions. PET is superior in providing biologic information about the cancer and is sensitive and highly specific. Integrated PET/MRI is a welcome technical advance with great potential to influence the diagnosis and management of prostate cancer in clinical practice. PMID- 27694164 TI - Utility of Ultrasound in the Diagnosis, Treatment, and Follow-up of Prostate Cancer: State of the Art. AB - Prostate cancer screening currently consists of serum prostate-specific antigen and digital rectal examination, followed by transrectal ultrasound-guided biopsy for diagnostic confirmation. Although the current paradigm of prostate cancer screening has led to a decrease in advanced disease and cancer-related mortality, these techniques have limitations in terms of sensitivity and specificity, resulting in missed cancers that are clinically significant and the overdetection of clinically insignificant cancers. New imaging techniques and technologies are required to improve the detection of prostate cancer. This article summarizes the use of novel ultrasound techniques and technologies in the detection, biopsy, and treatment of prostate cancer. PMID- 27694166 TI - Radiotheranostics in Prostate Cancer: Introduction and Overview. PMID- 27694165 TI - Bone-Targeted Imaging and Radionuclide Therapy in Prostate Cancer. AB - Although selective metabolic and receptor-based molecular agents will surely be included in the future of prostate cancer diagnosis and therapy, currently available inorganic compounds-such as 18F-NaF for the diagnosis of bony disease and 223RaCl2 for the therapy of bone metastases-were recently shown to be superior to standard 99mTc-phosphonates for diagnosis and 153Sm ethylenediaminetetramethylene phosphonate or 89SrCl2 for therapy. The advantages of 18F-NaF include improved lesion detection and, when used in combination with CT, improved diagnostic confidence and specificity. In addition to being the first approved alpha-emitter, 223RaCl2 is the first radiopharmaceutical to show an increase in overall survival, a decrease in skeletal events, palliation of bone pain, and a low profile of adverse reactions (which are mild and manageable). The management of metastatic bone disease with 223RaCl2 is uniquely satisfying, as patients can be monitored directly during their monthly treatment visits. PMID- 27694168 TI - Evaluation of Prostate Cancer with 11C-Acetate PET/CT. AB - In this article, we will first describe the metabolic fate of 11C-acetate; then discuss its biodistribution in health and disease; and subsequently focus on its key clinical applications, the detection and localization of prostate cancer tissue in patients with primary or recurrent disease. Finally, we will discuss the potential role of 11C-acetate in the context of other prostate cancer imaging probes and non-radionuclide-based imaging approaches. PMID- 27694167 TI - PET of Glucose Metabolism and Cellular Proliferation in Prostate Cancer. AB - Imaging of the Warburg effect, which is the principal but not the sole cause for enhanced glucose metabolism in tumors, with PET and 18F-FDG has become the mainstay for the imaging evaluation of several cancers. Despite the seemingly prevalent notion that 18F-FDG PET may not be useful in prostate cancer, relatively limited evidence suggests that this imaging modality can be useful for the evaluation of the extent of metastatic disease and the assessment of the therapy response and prognosis in men with castration-resistant prostate cancer. Incidental high focal 18F-FDG uptake in the prostate gland, although generally rare, may also indicate occult prostate cancer that may need to be further scrutinized. In general, 18F-FDG PET is not useful for initial staging and is of limited utility in the clinical setting of biochemical failure after prior definitive therapy for primary cancer. Although more experience is needed, it appears that the imaging of cellular proliferation with PET and 3'-deoxy-3'-18F fluorothymidine or 2'-18F-fluoro-5-methyl-1-beta-d-arabinofuranosyluracil may also allow for targeted biopsy and localization for focal therapy of aggressive prostate tumors as well as assessment of the therapy response to various standard and novel treatment regimens in patients with metastatic disease.

PMID- 27694169 TI - Evaluation of Prostate Cancer with 11C- and 18F-Choline PET/CT: Diagnosis and Initial Staging. AB - Early diagnosis and adequate staging are crucial for the choice of adequate treatment in prostate cancer (PC). Morphologic and functional imaging modalities, such as CT and MRI, have had limited accuracy in the diagnosis and nodal staging of PC. Molecular PET/CT imaging with 11C- or 18F-choline-labeled derivatives is increasingly being used, but its role in the diagnosis and initial staging of PC is controversial because of limitations in sensitivity and specificity for the detection of primary PC. For T staging, functional MRI is superior to 11C- or 18F choline PET/CT. For N staging, 11C- or 18F-choline PET/CT can provide potentially useful information that may influence treatment planning. For the detection of bone metastases, 11C- or 18F-choline PET/CT has had promising results; however, in terms of cost-effectiveness, the routine use of 11C- or 18F-choline PET/CT is still debatable. 11C- or 18F-choline PET/CT might be used in high-risk PC before radiation treatment planning, potentially affecting this planning (e.g., regarding dose escalation). This review provides an overview of the diagnostic accuracy and limitations of 11C- or 18F-choline PET/CT in the diagnosis and staging of PC. PMID- 27694171 TI - 11C- or 18F-Choline PET/CT for Imaging Evaluation of Biochemical Recurrence of Prostate Cancer. AB - Recurrence of prostate cancer is suspected when an increase in the prostate specific antigen level is detected after radical treatment; the recurrence could be local relapse, distant relapse, or both. Differentiation between the two patterns of relapse is critical for choosing the proper treatment strategy. Choline PET/CT could be of help in discriminating patients with local, lymph node, and bone recurrences, thus having an impact on patient management. PMID- 27694172 TI - Evaluation of Prostate Cancer with 11C-Choline PET/CT for Treatment Planning, Response Assessment, and Prognosis. AB - The aim of this review is to report on the value of 11C-choline PET imaging as a diagnostic procedure for metastasis-directed therapies. Furthermore, the role of 11C-choline PET/CT as a diagnostic tool for monitoring castration-resistant prostate cancer patients treated with systematic therapy is assessed. Finally, the role of 11C-choline PET/CT in the prediction of survival in both castration resistant prostate cancer patients and hormone-naive patients is investigated. PMID- 27694173 TI - Evaluation of Prostate Cancer Bone Metastases with 18F-NaF and 18F-Fluorocholine PET/CT. AB - 18F-fluorocholine is a specific promising agent for imaging tumor cell proliferation, particularly in prostate cancer, using PET/CT. It is a beneficial tool in the early detection of marrow-based metastases because it excludes distant metastases and evaluates the response to hormone therapy. In addition, 18F-fluorocholine has the potential to differentiate between degenerative and malignant osseous abnormalities because degenerative changes are not choline avid; however, the agent may accumulate in recent traumatic bony lesions. On the other hand, 18F-NaF PET/CT can indicate increased bone turnover and is generally used in the assessment of primary and secondary osseous malignancies, the evaluation of response to treatment, and the clarification of abnormalities on other imaging modalities or clinical data. 18F-NaF PET/CT is a highly sensitive method in the evaluation of bone metastases from prostate cancer, but it has problematic specificity, mainly because of tracer accumulation in degenerative and inflammatory bone diseases. In summary, 18F-NaF PET/CT is a highly sensitive method, but 18F-fluorocholine PET/CT can detect early bone marrow metastases and provide greater specificity in the detection of bone metastases in patients with prostate cancer. However, the difference seems not to be significant. PMID- 27694174 TI - Evaluation of Prostate Cancer with Radiolabeled Amino Acid Analogs. AB - Conventional imaging of prostate cancer has limitations related to the frequently indolent biology of the disease. PET is a functional imaging method that can exploit various aspects of tumor biology to enable greater detection of prostate cancer than can be provided by morphologic imaging alone. Radiotracers that are in use or under investigation for targeting salient features of prostate cancer include those directed to glucose, choline, acetate, prostate-specific membrane antigen, bombesin, and amino acids. The tumor imaging features of this last class of radiotracers mirror the upregulation of transmembrane amino acid transport that is necessary in carcinomas because of increased amino acid use for energy requirements and protein synthesis. Natural and synthetic amino acids radiolabeled for PET imaging have been investigated in prostate cancer patients. Early work with naturally occurring amino acid-derived radiotracers, such as l 11C-methionine and l-1-11C-5-hydroxytryptophan, demonstrated promising results, including greater sensitivity than 18F-FDG for intraprostatic and extraprostatic cancer detection. However, limitations with naturally occurring amino acid derived compounds, including metabolism of the radiotracer itself, led to the development of synthetic amino acid radiotracers, which are not metabolized and therefore more accurately reflect transmembrane amino acid transport. Of the synthetic amino acid-derived PET radiotracers, anti-1-amino-3-18F fluorocyclobutane-1-carboxylic acid (18F-FACBC or 18F-fluciclovine) has undergone the most promising translation to human use, including the availability of simplified radiosynthesis. Several studies have indicated advantageous biodistribution in the abdomen and pelvis with little renal excretion and bladder activity-characteristics beneficial for prostate cancer imaging. Studies have demonstrated improved lesion detection and diagnostic performance of 18F fluciclovine in comparison with conventional imaging, especially for recurrent prostate cancer, although issues with nonspecific uptake limit the potential role of 18F-fluciclovine in the diagnosis of primary prostate cancer. Although work is ongoing, recently published intrapatient comparisons of 18F-fluciclovine with 11C choline reported higher overall diagnostic performance of the former, especially for the detection of disease relapse. This review is aimed at providing a detailed overview of amino acid-derived PET compounds that have been studied for use in prostate cancer imaging. PMID- 27694175 TI - Bombesin-Targeted PET of Prostate Cancer. AB - Imaging plays an important role in prostate cancer (PC), including accurate evaluation of the extent of disease, assessment of sites of recurrent disease, and monitoring of response to treatment. Molecular imaging techniques are among the novel developments related to the imaging of PC, and various SPECT and PET radiopharmaceuticals are now available in clinical trials or commercially. Here we describe the preclinical and clinical use of gastrin-releasing peptide receptors as targets for the imaging of PC, with a focus on the development of PET tracers for the imaging of gastrin-releasing peptide receptor-positive tumors. PMID- 27694176 TI - What Medical, Urologic, and Radiation Oncologists Want from Molecular Imaging of Prostate Cancer. AB - As molecular imaging better delineates the state of prostate cancer, clinical management will evolve. The currently licensed imaging modalities are limited by lack of specificity or sensitivity for the extent of cancer and for predicting outcome in response to therapy. Clinicians want molecular imaging that-by being more reliable in tailoring treatment and monitoring response for each patient will become a key facet of precision medicine, surgery, and radiation therapy. Identifying patients who are candidates for specific or novel treatments is important, but equally important is the finding that a given patient may not be a good candidate for single-modality therapy. This article presents prostate cancer scenarios in which managing clinicians would welcome molecular imaging innovations to help with decision making. The potential role of newer techniques that may help fill this wish list is discussed. PMID- 27694177 TI - Evaluation of Castration-Resistant Prostate Cancer with Androgen Receptor-Axis Imaging. AB - Castration-resistant prostate cancer (CRPC) is the lethal form of prostate cancer, and more than 26,000 men will die from this disease in 2016. The pathophysiology of CRPC is clearly multifactorial, but most often, androgen receptor (AR) upregulation is associated with its earliest beginnings and the AR increase is part of the multimolecular complex including downstream effector proteins linked to AR (AR-axis) responsible for rapid proliferation and malignant features of the malignant cell. In both animal models and patients, glycolysis (Warburg effect) is also an early manifestation of CRPC transformation. At Memorial Sloan Kettering Cancer Center, we have focused our energies on imaging studies of the AR-axis in CRPC, using 18F-FDG, 18F-16beta-fluoro-5alpha dihydrotestosterone (18F-FDHT), and a variety of radiolabeled antibodies targeting downstream effectors, such as prostate-specific membrane antigen (PSMA). Small-molecular-weight PSMA-targeting agents are not part of this review. In this review, we will focus on molecular imaging of the AR-axis in metastatic CRPC (mCRPC) and discuss our personal experience with these tracers. Our goal is to put these radiopharmaceuticals in the context of mCRPC biology and diagnosis (e.g., 18F-FDHT). PMID- 27694178 TI - The Rise of PSMA Ligands for Diagnosis and Therapy of Prostate Cancer. AB - The prostate-specific membrane antigen (PSMA) has received increased consideration during the past few years as an excellent target for both imaging and therapy of prostate cancer. After many years of outstanding preclinical research, the first significant step forward in clinical use was achieved in 2008 with the first human experience with the small-molecule PSMA inhibitors 123I-MIP 1972 and 123I-MIP-1095. A clinical breakthrough followed in 2011 with 68Ga-PSMA 11 for PET imaging and 131I-MIP-1095 for endoradiotherapy of metastatic prostate cancer. Since then, PET/CT with 68Ga-PSMA-11 has rapidly spread worldwide, and endoradiotherapy with PSMA ligands has been conducted at increasing numbers of centers. 68Ga-PSMA-11 is currently the subject of multicenter studies in different countries. Since 2013, 131I-related PSMA therapy has been replaced by 177Lu-labeled ligands, such as PSMA-617, which is also the subject of multicenter studies. Alternative PSMA ligands for both imaging and therapy are available. Among them is 99mTc-MIP-1404, which has recently entered a phase 3 clinical trial. This article focuses on the highlights of the development and clinical application of PSMA ligands. PMID- 27694180 TI - PSMA-Based Radioligand Therapy for Metastatic Castration-Resistant Prostate Cancer: The Bad Berka Experience Since 2013. AB - A potential milestone in personalized nuclear medicine is theranostics of metastatic castration-resistant prostate cancer (mCRPC) based on molecular imaging using PET/CT with 68Ga-labeled prostate-specific membrane antigen (PSMA) ligands and molecular radiotherapy using PSMA-targeted radioligand therapy (PRLT) with 177Lu-PSMA ligands. 68Ga-PSMA PET/CT enables accurate detection of mCRPC lesions with high diagnostic sensitivity and specificity and provides quantitative and reproducible data that can be used to select patients for PRLT and therapeutic monitoring. Our comprehensive experience over the last 3 years using different radioligands indicates that PRLT is highly effective for the treatment of mCRPC, even in advanced cases, and potentially lends a significant benefit to overall and progression-free survival. Additionally, significant improvement in clinical symptoms and excellent palliation of pain can be achieved. PMID- 27694181 TI - Captures of Boll Weevils (Coleoptera: Curculionidae) in Relation to Trap Distance From Cotton Fields. AB - The boll weevil (Anthonomus grandis grandis Boheman) has been eradicated from much of the United States, but remains an important pest of cotton (Gossypium spp.) in other parts of the Americas. Where the weevil occurs, the pheromone trap is a key tool for population monitoring or detection. Traditional monitoring programs have placed traps in or near the outermost cotton rows where damage by farm equipment can cause loss of trapping data. Recently, some programs have adopted a trap placement adjacent to but outside monitored fields. The effects of these changes have not been previously reported. Captures of early-season boll weevils by traps near (<=1 m) or far (7-10 m) from the outermost cotton row were evaluated. In 2005, during renewed efforts to eradicate the boll weevil from the Lower Rio Grande Valley of Texas, far traps consistently captured more weevils than traps near cotton. Traps at both placements indicated similar patterns of early-season weevil captures, which were consistent with those previously reported. In 2006, no distinction between trap placements was detected. Early season patterns of captures in 2006 were again similar for both trap placements, but captures were much lower and less regular compared with those observed in 2005. These results suggest magnitude and likelihood of weevil capture in traps placed away from cotton are at least as high as for traps adjacent to cotton. Therefore, relocation of traps away from the outer rows of cotton should not negatively impact ability to monitor or detect the boll weevil. PMID- 27694179 TI - Prostate-Specific Membrane Antigen-Targeted Radiohalogenated PET and Therapeutic Agents for Prostate Cancer. AB - Radiohalogenated agents are often the first line of pursuit in the development of new radiopharmaceuticals-whether antibodies, peptides, or small molecules-because of their ease of synthesis, lack of substantial steric perturbation of the original affinity agent (in some cases, providing enhanced affinity), and capacity to be transformed into therapeutics (in some cases, with a mere switch of an isotope). They often provide proof of a principle before optimization for pharmacokinetics or generation of radiometallated agents, when the latter are necessary. In particular, 18F has been well integrated into normal clinical work flow in the form of 18F-FDG for oncologic imaging, with reliable daily production and distribution to sites for immediate use, without the need for on-site preparation. Here we discuss radiohalogenated versions of imaging and therapeutic agents targeting the prostate-specific membrane antigen (PSMA); these were among the first such agents to be synthesized and used clinically. PSMA is highly expressed on prostate cancer epithelial cells and is currently being extensively investigated around the world as a target for imaging and therapy of prostate cancer. Additionally, the presence of PSMA on nonprostate tumor neovasculature has opened the possibility of PSMA-targeted molecules as generalizable cancer imaging and therapy agents. We focus on 18F-labeled agents for PET, as they begin to redefine-along with the corresponding 68Ga-labeled agents discussed elsewhere in this supplement to The Journal of Nuclear Medicine-the management of prostate cancer across a variety of clinical contexts. PMID- 27694182 TI - Demographic Analysis of Sex Ratio on Population Growth of Bactrocera dorsalis (Diptera: Tephritidae) With Discussion of Control Efficacy Using Male Annihilation. AB - The life table data for the oriental fruit fly, Bactrocera dorsalis (Hendel), at different adult sex ratios (1?: 1?, 1?: 50?, 50?: 1? free-choice mating, and 50?: 1? no-choice mating) were collected to determine the effects of sex-ratio manipulation on current pest control procedures. At 1?: 1?, females mated, on average, 2.3 times during their lifetime with a mean fecundity (F) of 1,122 eggs. The net reproductive rate (R0), intrinsic rate of increase (r), finite rate (lambda), and mean generation time (T) were 561.0 offspring, 0.1693 d- 1, 1.1844 d- 1, and 37.4 d, respectively. At 50?: 1? free-choice mating, males mated 46.7 times during their lifetime, while at 50?: 1? no-choice mating, males mated on average 50 times during their lifetime, and all females mating only once in both treatments. The values for F, r, and lambda were significantly lower for both 50?: 1? treatments than those in the 1?: 1? group; the R0 values, however, were either equal to or even higher than those in the 1?: 1? treatment. In the male biased sex ratio (1?: 50?), fecundity was the highest (1,610 eggs) and female average life span the longest (166 d), while the R0 was the lowest (31.6 offspring) among all treatments. Population projections showed that even at a sex ratio of 50?: 1?, B. dorsalis could still produce a large number of offspring. These findings demonstrate that management strategies for controlling B. dorsalis could be properly evaluated by using demographic methods. Because female annihilation appears to be a more effective control strategy, it should be considered as a viable alternative. PMID- 27694183 TI - Phytophagy by the Mullein Bug (Hemiptera: Miridae) on Apples: Feeding Behavior and Fruit Damage. AB - : The zoophytophagous mullein bug, Campylomma verbasci (Meyer-Dur) (Hemiptera: Miridae), is a beneficial predator of mites and aphids, but also a pest causing damage when it feeds on apples. The aim of this study was to evaluate three different parameters of phytophagy of the mullein bug both in laboratory (phytophagous behavior) and field (fruit damage) tests: 1) apple cultivar, 2) fruit size, and 3) nymphal instar. In the laboratory, nymphs were observed individually for 15 min in Petri dishes containing agar gel and an apple fruitlet to evaluate feeding punctures of four apple cultivars, four fruit sizes, and five nymphal instars. In the orchard, nymphs were caged at bloom in sleeve cages to evaluate damage on the developing fruit of seven apple cultivars and three nymphal instars on 'Red Delicious'. The feeding punctures in the laboratory were higher on 'Red Delicious' than on 'Honeycrisp'; fruit damage in the orchard did not differ among cultivars at mid-season, but was higher on 'Red Delicious' than on 'Lobo' and 'Marshall McIntosh' at harvest. The number of feeding punctures in the laboratory was higher on 7-9 mm than on 18-20 mm size fruit for 'Red Delicious', but not for 'Honeycrisp'. The number of feeding punctures in the laboratory made by the fifth nymphal instar was higher than those made by younger nymphs, but fruit damage in the orchard did not differ among nymphal instars. Our results will help to elaborate a management chart for this insect by minimizing risks and promoting its use for biocontrol. RESUME: . : La punaise de la molene, Campylomma verbasci (Meyer-Dur) (Hemiptera: Miridae), est un predateur benefique zoophytophage des acariens et pucerons dans les vergers, mais egalement un ravageur causant des dommages lorsqu'il se nourrit sur les pommes. Le but de cette etude etait d'evaluer trois parametres differents sur la phytophagie de la punaise de la molene, a la fois en laboratoire (comportement phytophage) et sur le terrain (dommages aux fruits) : 1) les cultivars de pommes, 2) la taille des fruits, et 3) les stades larvaires. En laboratoire, les larves etaient observees individuellement pendant 15 min dans des boites de Petri contenant un gel d'agar et une jeune pomme afin de determiner les piqures de nutrition sur quatre cultivars de pommes, quatre tailles de fruit et cinq stades larvaires differents. En verger, des larves ont ete encagees a la floraison dans des manchons en mousseline afin d'evaluer les dommages sur les fruits en developpement. Les essais ont ete effectues sur sept cultivars de pommes ainsi qu'avec trois stades larvaires sur le cultivar "Delicieuse rouge". Les piqures de nutrition en laboratoire etaient plus nombreuses sur "Delicieuse rouge" que sur "Honeycrisp"; les dommages aux fruits en verger ne differaient pas entre les cultivars a mi saison, mais etaient plus nombreux sur "Delicieuse rouge" que sur "Lobo" et "Marshall McIntosh" a la recolte. Les piqures de nutrition en laboratoire etaient plus nombreuses pour la taille de fruit 7-9 mm que 18-20 mm sur "Delicieuse rouge", mais pas sur "Honeycrisp". Le nombre de piqures de nutrition (en laboratoire) faites par les larves de stade 5 etaient plus nombreuses que celles faites par les larves plus jeunes, mais les dommages aux fruits (en verger) ne differaient pas entre les stades larvaires. Ces resultats vont aider a elaborer une charte de gestion de cet insecte en minimisant les risques et en favorisant son role d'agent de lutte biologique. PMID- 27694185 TI - The Influence of Nature Stimulus in Enhancing the Birth Experience. AB - The physical environment is one of the factors that affect women's experience of labor. The basics of the childbirth process have not changed since the beginning of human existence; however, the environment in which women today give birth has changed significantly. Incorporating design elements and strategies that calm and reduce negative emotions may create positive experiences for women in labor. The purpose of this study was to examine the impact of one such strategy, namely, the presentation of images of nature, on the labor and delivery experience. The study findings showed that the experimental condition has a higher score on the Quality of Care From the Patient's Perspective (QPP) subscale. In addition, there was an increase in the QPP scores associated with the increase in Nature TV watching time, QPP mean of watching time (less than 1 hr) group, m = 4.5 and QPP mean of watching time (more than 3 hs), m = 4.8. The mean score for the heart rate was lower in the experimental condition, m = 84.60, than in the control one, m = 90.49. For Apgar, the mean score was higher for Group A, m = 8.65, and Group B, m = 8.92. These findings support the study hypothesis which states that the nature images would influence the labor experience positively. In addition, the findings emphasize the importance of incorporating nonpharmacological techniques in the labor and delivery room (LDR) units to sooth the pain. Adding nature imagery to the LDR environment can be one of these techniques. PMID- 27694187 TI - Basal cell carcinoma in two Hermann's tortoises (Testudo hermanni).

Herein we report the clinical behavior, antemortem diagnosis, and histopathologic characteristics of a recurrent intraoral keratinizing basal cell carcinoma (BCC) and a metastatic BCC of the carapace in 2 Hermann's tortoises (Testudo hermanni). Although squamous cell carcinomas (SCCs) in tortoises show similar predilection sites and gross pathologic features, the BCCs described in our report were characterized by a remarkably fast and highly infiltrative growth in comparison to SCCs. Accordingly, early diagnosis including reliable discrimination from SCC is essential toward the management of this neoplastic entity in tortoises.

AB - Activation of the guard cell S-type anion channel SLAC1 is important for stomatal closure in response to diverse stimuli, including elevated CO2 The majority of known SLAC1 activation mechanisms depend on abscisic acid (ABA) signaling. Several lines of evidence point to a parallel ABA-independent mechanism of CO2 induced stomatal regulation; however, molecular details of this pathway remain scarce. Here, we isolated a dominant mutation in the protein kinase HIGH LEAF TEMPERATURE1 (HT1), an essential regulator of stomatal CO2 responses, in an ozone sensitivity screen of Arabidopsis thaliana The mutation caused constitutively open stomata and impaired stomatal CO2 responses. We show that the mitogen activated protein kinases (MPKs) MPK4 and MPK12 can inhibit HT1 activity in vitro and this inhibition is decreased for the dominant allele of HT1. We also show that HT1 inhibits the activation of the SLAC1 anion channel by the protein kinases OPEN STOMATA1 and GUARD CELL HYDROGEN PEROXIDE-RESISTANT1 (GHR1) in Xenopus laevis oocytes. Notably, MPK12 can restore SLAC1 activation in the presence of HT1, but not in the presence of the dominant allele of HT1. Based on these data, we propose a model for sequential roles of MPK12, HT1, and GHR1 in the ABA-independent regulation of SLAC1 during CO2-induced stomatal closure.

AB - The aim of our study was to reveal the molecular basis of the serologic nontypeability of 2 Actinobacillus pleuropneumoniae field isolates. Nine field strains of A. pleuropneumoniae, the causative agent of porcine pleuropneumonia, were isolated from pigs raised on the same farm and sent to our diagnostic laboratory for serotyping. Seven of the 9 strains were identified as serovar 15 strains by immunodiffusion tests. However, 2 strains, designated FH24-2 and FH24 5, could not be serotyped with antiserum prepared against serovars 1-15. Strain FH24-5 showed positive results in 2 serovar 15-specific PCR tests, whereas strain FH24-2 was only positive in 1 of the 2 PCR tests. The nucleotide sequence analysis of gene clusters involved in capsular polysaccharide biosynthesis of the 2 nontypeable strains revealed that both had been rendered nontypeable by the action of ISApl1, a transposable element of A. pleuropneumoniae belonging to the IS30 family. The results showed that ISApl1 of A. pleuropneumoniae can interfere with both the serologic and molecular typing methods, and that nucleotide sequence analysis across the capsular gene clusters is the best means of determining the cause of serologic nontypeability in A. pleuropneumoniae.

PMID- 27694191 TI - Plasma concentration of serotonin is a novel biomarker for coronary microvascular dysfunction in patients with suspected angina and unobstructive coronary arteries. AB - Aims: Although the importance of coronary microvascular dysfunction (CMD) has been emerging, reliable biomarkers for CMD remain to be developed. We examined the potential usefulness of plasma concentration of serotonin to diagnose CMD in patients with suspected angina and unobstructive coronary arteries. Methods and results: We enrolled 198 consecutive patients (M/F 116/82, 60.2 +/- 13.3 years old) who underwent acetylcholine provocation test and measured plasma serotonin concentration. Coronary microvascular dysfunction was defined as myocardial lactate production without or prior to the occurrence of epicardial coronary spasm during acetylcholine provocation test. Although no statistical difference in plasma concentration of serotonin [median (inter-quartile range) nmol/L] was noted between the vasospastic angina (VSA) and non-VSA groups [6.8 (3.8, 10.9) vs. 5.1 (3.7, 8.4), P = 0.135], it was significantly higher in patients with CMD compared with those without it [7.7 (4.5, 14.2) vs. 5.6 (3.7, 9.3), P = 0.008]. Among the four groups classified according to the presence or absence of VSA and CMD, serotonin concentration was highest in the VSA with CMD group. Importantly, there was a positive correlation between plasma serotonin concentration and baseline thrombolysis in myocardial infarction frame count (P = 0.001), a marker of coronary vascular resistance. The classification and regression trees analysis showed that plasma serotonin concentration of 9.55 nmol/L was the first discriminator to stratify the risk for the presence of CMD. In multivariable analysis, serotonin concentration greater than the cut-off value had the largest odds ratio in the prediction of CMD [odds ratio (95% confidence interval) 2.63 (1.28-5.49), P = 0.009]. Conclusions: Plasma concentration of serotonin may be a novel biomarker for CMD in patients with angina and unobstructive coronary arteries.

AB - Motivation: Gene set enrichment (GSE) analysis allows researchers to efficiently extract biological insight from long lists of differentially expressed genes by interrogating them at a systems level. In recent years, there has been a proliferation of GSE analysis methods and hence it has become increasingly difficult for researchers to select an optimal GSE tool based on their particular dataset. Moreover, the majority of GSE analysis methods do not allow researchers to simultaneously compare gene set level results between multiple experimental conditions. Results: The ensemble of genes set enrichment analyses (EGSEA) is a method developed for RNA-sequencing data that combines results from twelve algorithms and calculates collective gene set scores to improve the biological relevance of the highest ranked gene sets. EGSEA's gene set database contains around 25 000 gene sets from sixteen collections. It has multiple visualization capabilities that allow researchers to view gene sets at various levels of granularity. EGSEA has been tested on simulated data and on a number of human and mouse datasets and, based on biologists' feedback, consistently outperforms the individual tools that have been combined. Our evaluation demonstrates the superiority of the ensemble approach for GSE analysis, and its utility to effectively and efficiently extrapolate biological functions and potential involvement in disease processes from lists of differentially regulated genes. Availability and Implementation: EGSEA is available as an R package at http://www.bioconductor.org/packages/EGSEA/ .

PMID- 27694198 TI - bTSSfinder: a novel tool for the prediction of promoters in cyanobacteria and Escherichia coli. AB - Motivation: The computational search for promoters in prokaryotes remains an attractive problem in bioinformatics. Despite the attention it has received for many years, the problem has not been addressed satisfactorily. In any bacterial genome, the transcription start site is chosen mostly by the sigma (sigma) factor proteins, which control the gene activation. The majority of published bacterial promoter prediction tools target sigma 70 promoters in Escherichia coli . Moreover, no sigma-specific classification of promoters is available for prokaryotes other than for E. coli . Results: Here, we introduce bTSSfinder, a novel tool that predicts putative promoters for five classes of sigma factors in Cyanobacteria (sigma A , sigma C , sigma H , sigma G and sigma F ) and for five classes of sigma factors in E. coli (sigma 70 , sigma 38 , sigma 32 , sigma 28 and sigma 24 ). Comparing to currently available tools, bTSSfinder achieves higher accuracy (MCC = 0.86, F 1 -score = 0.93) compared to the next best tool with MCC = 0.59, F 1 -score = 0.79) and covers multiple classes of promoters.

AB - Genomic samples of non-model organisms are becoming increasingly important in a broad range of studies from developmental biology, biodiversity analyses, to conservation. Genomic sample definition, description, quality, voucher information and metadata all need to be digitized and disseminated across scientific communities. This information needs to be concise and consistent in today's ever-increasing bioinformatic era, for complementary data aggregators to easily map databases to one another. In order to facilitate exchange of information on genomic samples and their derived data, the Global Genome Biodiversity Network (GGBN) Data Standard is intended to provide a platform based on a documented agreement to promote the efficient sharing and usage of genomic sample material and associated specimen information in a consistent way. The new data standard presented here build upon existing standards commonly used within the community extending them with the capability to exchange data on tissue, environmental and DNA sample as well as sequences. The GGBN Data Standard will reveal and democratize the hidden contents of biodiversity biobanks, for the convenience of everyone in the wider biobanking community. Technical tools exist for data providers to easily map their databases to the standard.Database URL: http://terms.tdwg.org/wiki/GGBN_Data_Standard. PMID- 27694207 TI - 3DFlu: database of sequence and structural variability of the influenza hemagglutinin at population scale. AB - The influenza virus type A (IVA) is an important pathogen which is able to cause annual epidemics and even pandemics. This fact is the consequence of the antigenic shifts and drifts capabilities of IVA, caused by the high mutation rate and the reassortment capabilities of the virus. The hemagglutinin (HA) protein constitutes the main IVA antigen and has a crucial role in the infection mechanism, being responsible for the recognition of host-specific sialic acid derivatives. Despite the relative abundance of HA sequence and serological studies, comparative structure-based analysis of HA are less investigated. The 3DFlu database contains well annotated HA representatives: 1192 models and 263 crystallographic structures. The relations between these proteins are defined using different metrics and are visualized as a network in the provided web interface. Moreover structural and sequence comparison of the proteins can be explored. Metadata information (e.g. protein identifier, IVA strain, year and location of infection) can enhance the exploration of the presented data. With our database researchers gain a useful tool for the exploration of high quality HA models, viewing and comparing changes in the HA viral subtypes at several information levels (sequence, structure, ESP). The complete and integrated view of those relations might be useful to determine the efficiency of transmission, pathogenicity and for the investigation of evolutionary tendencies of the influenza virus.Database URL: http://nucleus3d.cent.uw.edu.pl/influenza. PMID- 27694208 TI - ORDB, HORDE, ODORactor and other on-line knowledge resources of olfactory receptor-odorant interactions. AB - We present here an exploration of the evolution of three well-established, web based resources dedicated to the dissemination of information related to olfactory receptors (ORs) and their functional ligands, odorants. These resources are: the Olfactory Receptor Database (ORDB), the Human Olfactory Data Explorer (HORDE) and ODORactor. ORDB is a repository of genomic and proteomic information related to ORs and other chemosensory receptors, such as taste and pheromone receptors. Three companion databases closely integrated with ORDB are OdorDB, ORModelDB and OdorMapDB; these resources are part of the SenseLab suite of databases (http://senselab.med.yale.edu). HORDE (http://genome.weizmann.ac.il/horde/) is a semi-automatically populated database of the OR repertoires of human and several mammals. ODORactor (http://mdl.shsmu.edu.cn/ODORactor/) provides information related to OR-odorant interactions from the perspective of the odorant. All three resources are connected to each other via web-links.Database URL: http://senselab.med.yale.edu; http://genome.weizmann.ac.il/horde/; http://mdl.shsmu.edu.cn/ODORactor/. PMID- 27694209 TI - ASAP: a machine learning framework for local protein properties. AB - Determining residue-level protein properties, such as sites of post-translational modifications (PTMs), is vital to understanding protein function. Experimental methods are costly and time-consuming, while traditional rule-based computational methods fail to annotate sites lacking substantial similarity. Machine Learning (ML) methods are becoming fundamental in annotating unknown proteins and their heterogeneous properties. We present ASAP (Amino-acid Sequence Annotation Prediction), a universal ML framework for predicting residue-level properties. ASAP extracts numerous features from raw sequences, and supports easy integration of external features such as secondary structure, solvent accessibility, intrinsically disorder or PSSM profiles. Features are then used to train ML classifiers. ASAP can create new classifiers within minutes for a variety of tasks, including PTM prediction (e.g. cleavage sites by convertase, phosphoserine modification). We present a detailed case study for ASAP: CleavePred, an ASAP based model to predict protein precursor cleavage sites, with state-of-the-art results. Protein cleavage is a PTM shared by a wide variety of proteins sharing minimal sequence similarity. Current rule-based methods suffer from high false positive rates, making them suboptimal. The high performance of CleavePred makes it suitable for analyzing new proteomes at a genomic scale. The tool is attractive to protein design, mass spectrometry search engines and the discovery of new bioactive peptides from precursors. ASAP functions as a baseline approach for residue-level protein sequence prediction. CleavePred is freely accessible as a web-based application. Both ASAP and CleavePred are open-source with a flexible Python API.Database URL: ASAP's and CleavePred source code, webtool and tutorials are available at: https://github.com/ddofer/asap; http://protonet.cs.huji.ac.il/cleavepred. PMID- 27694210 TI - The BEL information extraction workflow (BELIEF): evaluation in the BioCreative V BEL and IAT track. AB - Network-based approaches have become extremely important in systems biology to achieve a better understanding of biological mechanisms. For network representation, the Biological Expression Language (BEL) is well designed to collate findings from the scientific literature into biological network models. To facilitate encoding and biocuration of such findings in BEL, a BEL Information Extraction Workflow (BELIEF) was developed. BELIEF provides a web-based curation interface, the BELIEF Dashboard, that incorporates text mining techniques to support the biocurator in the generation of BEL networks. The underlying UIMA based text mining pipeline (BELIEF Pipeline) uses several named entity recognition processes and relationship extraction methods to detect concepts and BEL relationships in literature. The BELIEF Dashboard allows easy curation of the automatically generated BEL statements and their context annotations. Resulting BEL statements and their context annotations can be syntactically and semantically verified to ensure consistency in the BEL network. In summary, the workflow supports experts in different stages of systems biology network building. Based on the BioCreative V BEL track evaluation, we show that the BELIEF Pipeline automatically extracts relationships with an F-score of 36.4% and fully correct statements can be obtained with an F-score of 30.8%. Participation in the BioCreative V Interactive task (IAT) track with BELIEF revealed a systems usability scale (SUS) of 67. Considering the complexity of the task for new users learning BEL, working with a completely new interface, and performing complex curation-a score so close to the overall SUS average highlights the usability of BELIEF.Database URL: BELIEF is available at http://www.scaiview.com/belief/. PMID- 27694212 TI - Professionals' perspectives towards health promotion in residential aged care: an explorative study in Austria. AB - Following the trend in most developed countries, in Austria the oldest old are the fastest growing population group. Among this group, there is a high prevalence of multimorbidity, functional impairment, dementia and psychiatric conditions. While health promotion (HP) has been considered relevant in coping with the challenges of an aging population, it has so far been viewed as a foreign concept in relation to the oldest old, especially those living in residential aged care (RAC) facilities. Although there is an acknowledgement that HP should be integrated into routine nursing, there has been little research on how professionals working with RAC interpret and implement HP. In this study, 13 semi-structured interviews were carried out with professionals from four major Austrian RAC providers. The data were analysed using thematic analysis. The findings show that, typically, professionals understand HP as a concept that is oriented towards maintaining potentials and resources, thereby promoting self determination, autonomy and social integration, including frail and functionally impaired elderly residents. However, data analysis also revealed a gap between the conceptual understanding and positive attitudes towards HP and its implementation in practice. Implementation of HP seems to occur in isolated cases, related to specific health issues. It seems that more complex HP approaches, especially the 'settings approach', are hardly practiced. To implement more comprehensive and systematic HP in Austrian RAC, support from external HP agencies as well as changes in financial incentives are needed. PMID- 27694211 TI - Ligand-induced growth and compaction of CD36 nanoclusters enriched in Fyn induces Fyn signaling. AB - Nanoclustering is an emerging organizational principle for membrane-associated proteins. The functional consequences of nanoclustering for receptor signaling remain largely unknown. Here, we applied quantitative multi-channel high- and super-resolution imaging to analyze the endothelial cell surface receptor CD36, the clustering of which upon binding to multivalent ligands, such as the anti angiogenic factor thrombospondin-1 (TSP-1), is thought to be crucial for signaling. We found that a substantial fraction of unligated CD36 exists in nanoclusters, which not only promote TSP-1 binding but are also enriched with the downstream effector Fyn. Exposure to multivalent ligands (TSP-1 or anti-CD36 IgM) that result in larger and denser CD36 clusters activates Fyn. Conversely, pharmacological perturbations that prevent the enhancement of CD36 clustering by TSP-1 abrogate Fyn activation. In both cases, there is no detectable change in Fyn enrichment at CD36 nanoclusters. These observations reveal a crucial role for the basal organization of a receptor into nanoclusters that are enriched with the signal-transducing downstream effectors of that receptor, such that enhancement of clustering by multivalent ligands is necessary and sufficient to activate the downstream effector without the need for its de novo recruitment. PMID- 27694213 TI - Effects of various types of anesthesia on hemodynamics, cardiac function, and glucose and lipid metabolism in rats. AB - Anesthesia can affect respiratory, circulatory, and endocrine systems but is necessary for certain experimental procedures such as echocardiography and blood sampling in small animals. We have now investigated the effects of four types of anesthesia [pentobarbital sodium (PENT), ketamine-xylazine (K/X), and low- or high-dose isoflurane (ISO)] on hemodynamics, cardiac function, and glucose and lipid metabolism in Sprague-Dawley rats. Aortic pressure, heart rate, and echocardiographic parameters were measured at various time points up to 45 min after the induction of anesthesia, and blood was then collected for measurement of parameters of glucose and lipid metabolism. Systolic aortic pressure remained constant in the PENT group, whereas it showed a biphasic pattern in the K/X group and a gradual decline in the ISO groups. Marked bradycardia was observed in the K/X group. The serum glucose concentration was increased and the plasma insulin level was reduced in the K/X and ISO groups compared with the PENT group. The concentrations of free fatty acids and norepinephrine in plasma were increased in the K/X group. Despite the metabolic effects of K/X and ISO, our results suggest that the marked bradycardic effect of K-X renders this combination appropriate for measurement of Doppler-derived indexes of left ventricular diastolic function, whereas the relative ease with which the depth of anesthesia can be controlled with ISO makes it suitable for manipulations or data collection over long time periods. On the other hand, PENT may be best suited for experiments that focus on measurement of cardiac function by M-mode echocardiography and metabolic parameters. PMID- 27694214 TI - Dyssynchronous calcium removal in heart failure-induced atrial remodeling. AB - We tested the hypothesis that in atrial myocytes from a rabbit left ventricular heart failure (HF) model, spatial inhomogeneity and temporal dyssynchrony of Ca removal during excitation-contraction coupling together with increased Na/Ca exchange (NCX) activity generate a substrate for proarrhythmic Ca release. Ca removal occurs via Ca reuptake into the sarcoplasmic reticulum and extrusion via NCX exclusively in the cell periphery since rabbit atrial myocytes lack transverse tubules. Ca removal kinetics were assessed by the time constant tau of decay of local peripheral subsarcolemmal (SS) and central (CT) action potential (AP)-induced Ca transients (CaTs) recorded in confocal line scan mode (using Fluo 4). Spatial and temporal dyssynchrony of Ca removal was quantified by CV TAU, defined as the standard deviation of local tau along the transverse cell axis divided by mean tau. In normal cells CT CaT decline was slower compared with the SS domain, while in HF cells decline was accelerated, became equal in SS and CT regions, and a significant increase of CV TAU indicated an increased Ca removal dyssynchrony. In HF atrial cells NCX upregulation was accompanied by an overall higher incidence of spontaneous Ca waves and a higher propensity of arrhythmogenic Ca waves, defined as waves that triggered APs due to NCX-mediated membrane depolarization. NCX inhibition normalized CV TAU in HF atrial cells and decreased the propensity of Ca waves. In summary, HF atrial myocytes show accelerated but dyssynchronous diastolic Ca removal and altered sarcoplasmic reticulum Ca-ATPase (SERCA) and NCX activity that result in increased susceptibility to arrhythmia. PMID- 27694216 TI - Dietary nitrate supplementation attenuates the reduction in exercise tolerance following blood donation. AB - We tested the hypothesis that dietary nitrate (NO3-)-rich beetroot juice (BR) supplementation could partially offset deteriorations in O2 transport and utilization and exercise tolerance after blood donation. Twenty-two healthy volunteers performed moderate-intensity and ramp incremental cycle exercise tests prior to and following withdrawal of ~450 ml of whole blood. Before donation, all subjects consumed seven 70-ml shots of NO3--depleted BR [placebo (PL)] in the 48 h preceding the exercise tests. During the 48 h after blood donation, subjects consumed seven shots of BR (each containing 6.2 mmol of NO3-, n = 11) or PL (n = 11) before repeating the exercise tests. Hemoglobin concentration and hematocrit were reduced by ~8-9% following blood donation (P < 0.05), with no difference between the BR and PL groups. Steady-state O2 uptake during moderate-intensity exercise was ~4% lower after than before donation in the BR group (P < 0.05) but was unchanged in the PL group. The ramp test peak power decreased from predonation (341 +/- 70 and 331 +/- 68 W in PL and BR, respectively) to postdonation (324 +/- 69 and 322 +/- 66 W in PL and BR, respectively) in both groups (P < 0.05). However, the decrement in performance was significantly less in the BR than PL group (2.7% vs. 5.0%, P < 0.05). NO3- supplementation reduced the O2 cost of moderate-intensity exercise and attenuated the decline in ramp incremental exercise performance following blood donation. These results have implications for improving functional capacity following blood loss. PMID- 27694215 TI - Physiological and hypoxic oxygen concentration differentially regulates human c Kit+ cardiac stem cell proliferation and migration. AB - Cardiac stem cells (CSCs) are being evaluated for their efficacy in the treatment of heart failure. However, numerous factors impair the exogenously delivered cells' regenerative capabilities. Hypoxia is one stress that contributes to inadequate tissue repair. Here, we tested the hypothesis that hypoxia impairs cell proliferation, survival, and migration of human CSCs relative to physiological and room air oxygen concentrations. Human endomyocardial biopsy derived CSCs were isolated, selected for c-Kit expression, and expanded in vitro at room air (21% O2). To assess the effect on proliferation, survival, and migration, CSCs were transferred to physiological (5%) or hypoxic (0.5%) O2 concentrations. Physiological O2 levels increased proliferation (P < 0.05) but did not affect survival of CSCs. Although similar growth rates were observed in room air and hypoxia, a significant reduction of beta-galactosidase activity ( 4,203 fluorescent units, P < 0.05), p16 protein expression (0.58-fold, P < 0.001), and mitochondrial content (0.18-fold, P < 0.001) in hypoxia suggests that transition from high (21%) to low (0.5%) O2 reduces senescence and promotes quiescence. Furthermore, physiological O2 levels increased migration (P < 0.05) compared with room air and hypoxia, and treatment with mesenchymal stem cell conditioned media rescued CSC migration under hypoxia to levels comparable to physiological O2 migration (2-fold, P < 0.05 relative to CSC media control). Our finding that physiological O2 concentration is optimal for in vitro parameters of CSC biology suggests that standard room air may diminish cell regenerative potential. This study provides novel insights into the modulatory effects of O2 concentration on CSC biology and has important implications for refining stem cell therapies. PMID- 27694217 TI - Carboxy-terminal deletion of the HDL receptor reduces receptor levels in liver and steroidogenic tissues, induces hypercholesterolemia, and causes fatal heart disease. AB - The HDL receptor SR-BI mediates the transfer of cholesteryl esters from HDL to cells and controls HDL abundance and structure. Depending on the genetic background, loss of SR-BI causes hypercholesterolemia, anemia, reticulocytosis, splenomegaly, thrombocytopenia, female infertility, and fatal coronary heart disease (CHD). The carboxy terminus of SR-BI (505QEAKL509) must bind to the cytoplasmic adaptor PDZK1 for normal hepatic-but not steroidogenic cell expression of SR-BI protein. To determine whether SR-BI's carboxy terminus is also required for normal protein levels in steroidogenic cells, we introduced into SR-BI's gene a 507Ala/STOP mutation that produces a truncated receptor (SR BIDeltaCT). As expected, the dramatic reduction of hepatic receptor protein in SR BIDeltaCT mice was similar to that in PDZK1 knockout (KO) mice. Unlike SR-BI KO females, SR-BIDeltaCT females were fertile. The severity of SR-BIDeltaCT mice's hypercholesterolemia was intermediate between those of SR-BI KO and PDZK1 KO mice. Substantially reduced levels of the receptor in adrenal cortical cells, ovarian cells, and testicular Leydig cells in SR-BIDeltaCT mice suggested that steroidogenic cells have an adaptor(s) functionally analogous to hepatic PDZK1. When SR-BIDeltaCT mice were crossed with apolipoprotein E KO mice (SR BIDeltaCT/apoE KO), pathologies including hypercholesterolemia, macrocytic anemia, hepatic and splenic extramedullary hematopoiesis, massive splenomegaly, reticulocytosis, thrombocytopenia, and rapid-onset and fatal occlusive coronary arterial atherosclerosis and CHD (median age of death: 9 wk) were observed. These results provide new insights into the control of SR-BI in steroidogenic cells and establish SR-BIDeltaCT/apoE KO mice as a new animal model for the study of CHD. PMID- 27694218 TI - Exercise-induced brachial artery blood flow and vascular function is impaired in systemic sclerosis. AB - Systemic sclerosis (SSc) is a rare autoimmune disease characterized by debilitating fibrosis and vascular dysfunction; however, little is known about the circulatory response to exercise in this population. Therefore, we examined the peripheral hemodynamic and vasodilatory responses to handgrip exercise in 10 patients with SSc (61 +/- 4 yr) and 15 age-matched healthy controls (56 +/- 5 yr). Brachial artery diameter, blood flow, and mean arterial pressure (MAP) were determined at rest and during progressive static-intermittent handgrip exercise. Patients with SSc and controls were similar in body stature, handgrip strength, and MAP; however, brachial artery blood flow at rest was nearly twofold lower in patients with SSc compared with controls (22 +/- 4 vs. 42 +/- 5 ml/min, respectively; P < 0.05). Additionally, SSc patients had an ~18% smaller brachial artery lumen diameter with an ~28% thicker arterial wall at rest (P < 0.05). Although, during handgrip exercise, there were no differences in MAP between the groups, exercise-induced hyperemia and therefore vascular conductance were ~35% lower at all exercise workloads in patients with SSc (P < 0.05). Brachial artery vasodilation, as assessed by the relationship between Deltabrachial artery diameter and Deltashear rate, was significantly attenuated in the patients with SSc (P < 0.05). Finally, vascular dysfunction in the patients with SSc was accompanied by elevated blood markers of oxidative stress and attenuated endogenous antioxidant activity (P < 0.05). Together, these findings reveal attenuated exercise-induced brachial artery blood flow and conduit arterial vasodilatory dysfunction during handgrip exercise in SSc and suggest that elevated oxidative stress may play a role. PMID- 27694221 TI - New gene editing technique CRISPR-Cas9 raises important ethical questions, says advisory body. PMID- 27694220 TI - Exposure to cigarette smoke abrogates the beneficial effect of ischemic postconditioning. AB - Cigarette smoking is one of the risk factors for coronary artery disease. Although conditioning decreases infarct size in hearts from healthy animals, comorbidities may render it ineffective. We investigated the effects of cigarette smoke (CS) exposure on intracellular myocardial signaling, infarct size after ischemia-reperfusion, and the potential interference with ischemic conditioning. Exposure of mice to CS increased blood pressure, caused cardiac hypertrophy, and upregulated the nitric oxide synthatse (NOS)/soluble guanylate cyclase (sGC)/cGMP pathway. To test the effect of CS exposure on the endogenous cardioprotective mechanisms, mice were subjected to regional myocardial ischemia and reperfusion with no further intervention or application of preconditioning (PreC) or postconditioning (PostC). Exposure to CS did not increase the infarction compared with the room air (RA)-exposed group. PreC was beneficial for both CS and RA vs. nonconditioned animals. PostC was effective only in RA animals, while the infarct size-limiting effect was not preserved in the CS group. Differences in oxidative stress markers, Akt, and endothelial NOS phosphorylation and cGMP levels were observed between RA and CS groups subjected to PostC. In conclusion, exposure to CS does not per se increase infarct size. The beneficial effect of ischemic PreC is preserved in mice exposed to CS, as it does not affect the cardioprotective signaling; in contrast, PostC fails to protect CS-exposed mice due to impaired activation of the Akt/eNOS/cGMP axis that occurs in parallel to enhanced oxidative stress.

PMID- 27694219 TI - FOXO3a regulates BNIP3 and modulates mitochondrial calcium, dynamics, and function in cardiac stress. AB - The forkhead box O3a (FOXO3a) transcription factor has been shown to regulate glucose metabolism, muscle atrophy, and cell death in postmitotic cells. Its role in regulation of mitochondrial and myocardial function is not well studied. Based on previous work, we hypothesized that FOXO3a, through BCL2/adenovirus E1B 19-kDa protein-interacting protein 3 (BNIP3), modulates mitochondrial morphology and function in heart failure (HF). We modulated the FOXO3a-BNIP3 pathway in normal and phenylephrine (PE)-stressed adult cardiomyocytes (ACM) in vitro and developed a cardiotropic adeno-associated virus serotype 9 encoding dominant-negative FOXO3a (AAV9.dn-FX3a) for gene delivery in a rat model of HF with preserved ejection fraction (HFpEF). We found that FOXO3a upregulates BNIP3 expression in normal and PE-stressed ACM, with subsequent increases in mitochondrial Ca2+, leading to decreased mitochondrial membrane potential, mitochondrial fragmentation, and apoptosis. Whereas dn-FX3a attenuated the increase in BNIP3 expression and its consequences in PE-stressed ACM, AAV9.dn-FX3a delivery in an experimental model of HFpEF decreased BNIP3 expression, reversed adverse left ventricular remodeling, and improved left ventricular systolic and, particularly, diastolic function, with improvements in mitochondrial structure and function. Moreover, AAV9.dn-FX3a restored phospholamban phosphorylation at S16 and enhanced dynamin-related protein 1 phosphorylation at S637. Furthermore, FOXO3a upregulates maladaptive genes involved in mitochondrial apoptosis, autophagy, and cardiac atrophy. We conclude that FOXO3a activation in cardiac stress is maladaptive, in that it modulates Ca2+ cycling, Ca2+ homeostasis, and mitochondrial dynamics and function. Our results suggest an important role of FOXO3a in HF, making it an attractive potential therapeutic target. PMID- 27694223 TI - Sequential analysis of soil factors related to common scab of potatoes. AB - The severity of common scab (CS) of potatoes has been correlated with multiple environmental factors. This study aimed at separating the effect of factors related to local conditions from those correlated to the disease development at all studied sites using a mathematical adjustment of the variables' means for site and field. The experiment was conducted at two sites differing in soil conditions, where a field with low disease severity occurs next to one with high severity. Three cultivars susceptible to CS were grown in four replicates on each field. Bacteria, actinobacteria and the txtB gene, involved in the biosynthesis of the main CS pathogenicity factor, thaxtomin, were quantified by real-time PCR. Bulk soil, tuberosphere soil and potato periderm were characterized by carbon, nitrogen, phosphorus, sulfur, calcium, magnesium and iron contents. The adjustment of the data for field effects eliminated the confounding local conditions and showed that at all fields the CS severity was negatively correlated with soil S content while the number of txtB gene copies was positively correlated with soil C and N contents. Thus, those factors might have a more general relationship to the pathogen occurrence and disease severity, which needs to be verified in other environmental conditions. PMID- 27694226 TI - Pharmacokinetics and Differential Regulation of Cytochrome P450 Enzymes in Type 1 Allergic Mice. AB - Type 1 allergic diseases are characterized by elevated production of specific immunoglobulin E (IgE) for each antigen and have become a significant health problem worldwide. This study investigated the effect of IgE-mediated allergy on drug pharmacokinetics. To further understand differential suppression of hepatic cytochrome P450 (P450) activity, we examined the inhibitory effect of nitric oxide (NO), a marker of allergic conditions. Seven days after primary sensitization (PS7) or secondary sensitization (SS7), hepatic CYP1A2, CYP2C, CYP2E1, and CYP3A activities were decreased to 45%-75% of the corresponding control; however, CYP2D activity was not downregulated. PS7 and SS7 did not change the expression levels of five P450 proteins. Disappearance of CYP1A2 and CYP2D substrates from the plasma was not significantly different between allergic mice and control mice. In contrast, the area under the curve of a CYP1A2-mediated metabolite in PS7 and SS7 mice was reduced by 50% of control values. Total clearances of a CYP2E1 substrate in PS7 and SS7 mice were significantly decreased to 70% and 50% respectively, of the control without altering plasma protein binding. Hepatic amounts of CYP1A2 and CYP2E1 substrates were enhanced by allergic induction, being responsible for each downregulated activity. NO scavenger treatment completely improved the downregulated P450 activities. Therefore, our data suggest that the onset of IgE-mediated allergy alters the pharmacokinetics of major P450-metabolic capacity-limited drugs except for CYP2D drugs. NO is highly expected to participate in regulatory mechanisms of the four P450 isoforms. PMID- 27694227 TI - Validity and reliability of the South African health promoting schools monitoring questionnaire. AB - Health promoting schools, as conceptualised by the World Health Organisation, have been developed in many countries to facilitate the health-education link. In 1994, the concept of health promoting schools was introduced in South Africa. In the process of becoming a health promoting school, it is important for schools to monitor and evaluate changes and developments taking place. The Health Promoting Schools (HPS) Monitoring Questionnaire was developed to obtain opinions of students about their school as a health promoting school. It comprises 138 questions in seven sections: socio-demographic information; General health promotion programmes; health related Skills and knowledge; Policies; Environment; Community-school links; and support Services. This paper reports on the reliability and face validity of the HPS Monitoring Questionnaire. Seven experts reviewed the questionnaire and agreed that it has satisfactory face validity. A test-retest reliability study was conducted with 83 students in three high schools in Cape Town, South Africa. The kappa-coefficients demonstrate mostly fair (kappa-scores between 0.21 and 0.4) to moderate (kappa-scores between 0.41 and 0.6) agreement between test-retest General and Environment items; poor (kappa scores up to 0.2) agreement between Skills and Community test-retest items, fair agreement between Policies items, and for most of the questions focussing on Services a fair agreement was found. The study is a first effort at providing a tool that may be used to monitor and evaluate students' opinions about changes in health promoting schools. Although the HPS Monitoring Questionnaire has face validity, the results of the reliability testing were inconclusive. Further research is warranted.

AB - The World Health Organization recommend the Equity-Focused Health Impact Assessment (HIA) as a means to assess the impact of social and economic policies on the health of populations, and acknowledges their contribution to health inequality. We describe the application of the Equity-focused Impact Assessment methodology on the Portuguese law on Smoking Prevention and Tobacco Control (Law No. 37/2007). A rapid assessment was carried out to issue recommendations which could be incorporated into the law during a revision in 2014. Quantitative (consumption and health status indicators; equity analysis) and qualitative (Focus Group) approaches were taken to evaluate the impact of the law and formulate recommendations. Young people, men and women of low socioeconomic status, and pregnant women were identified as requiring specific and appropriate interventions to prevent smoking and support smoking cessation. PMID- 27694229 TI - Phosphinothricin Acetyltransferases Identified Using In Vivo, In Vitro, and Bioinformatic Analyses. AB - Acetylation of small molecules is widespread in nature, and in some cases, cells use this process to detoxify harmful chemicals. Streptomyces species utilize a Gcn5 N-acetyltransferase (GNAT), known as Bar, to acetylate and detoxify a self produced toxin, phosphinothricin (PPT), a glutamate analogue. Bar homologues, such as MddA from Salmonella enterica, acetylate methionine analogues such as methionine sulfoximine (MSX) and methionine sulfone (MSO), but not PPT, even though Bar homologues are annotated as PPT acetyltransferases. S. enterica was used as a heterologous host to determine whether or not putative PPT acetyltransferases from various sources could acetylate PPT, MSX, and MSO. In vitro and in vivo analyses identified substrates acetylated by putative PPT acetyltransferases from Deinococcus radiodurans (DR_1057 and DR_1182) and Geobacillus kaustophilus (GK0593 and GK2920). In vivo, synthesis of DR_1182, GK0593, and GK2920 blocked the inhibitory effects of PPT, MSX, and MSO. In contrast, DR_1057 did not detoxify any of the above substrates. Results of in vitro studies were consistent with the in vivo results. In addition, phylogenetic analyses were used to predict the functionality of annotated PPT acetyltransferases in Burkholderia xenovorans, Bacillus subtilis, Staphylococcus aureus, Acinetobacter baylyi, and Escherichia coli IMPORTANCE: The work reported here provides an example of the use of a heterologous system for the identification of enzyme function. Many members of this superfamily of proteins do not have a known function, or it has been annotated solely on the basis of sequence homology to previously characterized enzymes. The critical role of Gcn5 N-acetyltransferases (GNATs) in the modulation of central metabolic processes, and in controlling metabolic stress, necessitates approaches that can reveal their physiological role. The combination of in vivo, in vitro, and bioinformatics approaches reported here identified GNATs that can acetylate and detoxify phosphinothricin. PMID- 27694230 TI - Interactions of Plutonium with Pseudomonas sp. Strain EPS-1W and Its Extracellular Polymeric Substances. AB - : Safe and effective nuclear waste disposal, as well as accidental radionuclide releases, necessitates our understanding of the fate of radionuclides in the environment, including their interaction with microorganisms. We examined the sorption of Pu(IV) and Pu(V) to Pseudomonas sp. strain EPS-1W, an aerobic bacterium isolated from plutonium (Pu)-contaminated groundwater collected in the United States at the Nevada National Security Site (NNSS) in Nevada. We compared Pu sorption to cells with and without bound extracellular polymeric substances (EPS). Wild-type cells with intact EPS sorbed Pu(V) more effectively than cells with EPS removed. In contrast, cells with and without EPS showed the same sorption affinity for Pu(IV). In vitro experiments with extracted EPS revealed rapid reduction of Pu(V) to Pu(IV). Transmission electron microscopy indicated that 2- to 3-nm nanocrystalline Pu(IV)O2 formed on cells equilibrated with high concentrations of Pu(IV) but not Pu(V). Thus, EPS, while facilitating Pu(V) reduction, inhibit the formation of nanocrystalline Pu(IV) precipitates. IMPORTANCE: Our results indicate that EPS are an effective reductant for Pu(V) and sorbent for Pu(IV) and may impact Pu redox cycling and mobility in the environment. Additionally, the resulting Pu morphology associated with EPS will depend on the concentration and initial Pu oxidation state. While our results are not directly applicable to the Pu transport situation at the NNSS, the results suggest that, in general, stationary microorganisms and biofilms will tend to limit the migration of Pu and provide an important Pu retardation mechanism in the environment. In a broader sense, our results, along with a growing body of literature, highlight the important role of microorganisms as producers of redox active organic ligands and therefore as modulators of radionuclide redox transformations and complexation in the subsurface. PMID- 27694231 TI - Genomic Comparisons of Lactobacillus crispatus and Lactobacillus iners Reveal Potential Ecological Drivers of Community Composition in the Vagina. AB - : Lactobacillus crispatus and Lactobacillus iners are common inhabitants of the healthy human vagina. These two species are closely related and are thought to perform similar ecological functions in the vaginal environment. Temporal data on the vaginal microbiome have shown that nontransient instances of cooccurrence are uncommon, while transitions from an L. iners-dominated community to one dominated by L. crispatus, and vice versa, occur often. This suggests that there is substantial overlap in the fundamental niches of these species. Given this apparent niche overlap, it is unclear how they have been maintained as common inhabitants of the human vagina. In this study, we characterized and compared the genomes of L. iners and L. crispatus to gain insight into possible mechanisms driving the maintenance of this species diversity. Our results highlight differences in the genomes of these two species that may facilitate the partitioning of their shared niche space. Many of the identified differences may impact the protective benefits provided to the host by these two species. IMPORTANCE: The microbial communities that inhabit the human vagina play a critical role in the maintenance of vaginal health through the production of lactic acid and lowering the environmental pH. This precludes the growth of nonindigenous organisms and protects against infectious disease. The two most common types of vaginal communities are dominated by either Lactobacillus iners or Lactobacillus crispatus, while some communities alternate between the two over time. We combined ecological theory with state-of-the-art genome analyses to characterize how these two species might partition their shared niche space in the vagina. We show that the genomes of L. iners and L. crispatus differ in many respects, several of which may drive differences in their competitive abilities in the vagina. Our results provide insight into factors that drive the complicated temporal dynamics of the vaginal microbiome and demonstrate how closely related microbial species partition shared fundamental niche space. PMID- 27694233 TI - Freshwater bacteria release methane as a byproduct of phosphorus acquisition. AB - : Freshwater lakes emit large amounts of methane, some of which is produced in oxic surface waters. Two potential pathways for aerobic methane production exist: methanogenesis in oxygenated water, which has been observed in some lakes, or demethylation of small organic molecules. Although methane is produced via demethylation in oxic marine environments, this mechanism of methane release has not yet been demonstrated in freshwater systems. Genes related to the C-P lyase pathway, which cleaves C-P bonds in phosphonate compounds, were found in a metagenomic survey of the surface water of Lake Matano, which is chronically P starved and methane-rich. We demonstrate that four bacterial isolates from Lake Matano obtain P from methylphosphonate and release methane, and that this activity is repressed by phosphate. We further demonstrate that expression of phnJ, which encodes the enzyme that releases methane, is higher in the presence of methylphosphonate and lower when both methylphosphonate and phosphate are added. This gene is also found in most of the metagenomic data sets from freshwater environments. These experiments link methylphosphonate degradation and methane production with gene expression and phosphate availability in freshwater organisms, and suggest that some of the excess methane in the Lake Matano surface water, and in other methane-rich lakes, may be produced by P-starved bacteria. IMPORTANCE: Methane is an important greenhouse gas, and contributes substantially to global warming. Although freshwater environments are known to release methane into the atmosphere, estimates of the amount of methane emitted by freshwater lakes vary from 8 to 73 Tg per year. Methane emissions are difficult to predict in part because the source of the methane can vary: it is the end product of the energy-conserving pathway in methanogenic archaea, which predominantly live in anoxic sediments or waters, but have also been identified in some oxic freshwater environments. More recently, methane release from small organic molecules has been observed in oxic marine environments. Here we show that demethylation of methylphosphonate may also contribute to methane release from lakes, and that phosphate can repress this activity. Since lakes are typically phosphorus limited, some methane release in these environments may be a byproduct of phosphorus metabolism, rather than carbon or energy metabolism. Methane emissions from lakes are currently predicted using primary production, eutrophication status, extent of anoxia, and the shape and size of the lake; to improve prediction of methane emissions, phosphorus availability and sources may also need to be included in these models. PMID- 27694232 TI - Listeria monocytogenes in Stone Fruits Linked to a Multistate Outbreak: Enumeration of Cells and Whole-Genome Sequencing. AB - : In 2014, the identification of stone fruits contaminated with Listeria monocytogenes led to the subsequent identification of a multistate outbreak. Simultaneous detection and enumeration of L. monocytogenes were performed on 105 fruits, each weighing 127 to 145 g, collected from 7 contaminated lots. The results showed that 53.3% of the fruits yielded L. monocytogenes (lower limit of detection, 5 CFU/fruit), and the levels ranged from 5 to 2,850 CFU/fruit, with a geometric mean of 11.3 CFU/fruit (0.1 CFU/g of fruit). Two serotypes, IVb-v1 and 1/2b, were identified by a combination of PCR- and antiserum-based serotyping among isolates from fruits and their packing environment; certain fruits contained a mixture of both serotypes. Single nucleotide polymorphism (SNP)-based whole-genome sequencing (WGS) analysis clustered isolates from two case-patients with the serotype IVb-v1 isolates and distinguished outbreak-associated isolates from pulsed-field gel electrophoresis (PFGE)-matched, but epidemiologically unrelated, clinical isolates. The outbreak-associated isolates differed by up to 42 SNPs. All but one serotype 1/2b isolate formed another WGS cluster and differed by up to 17 SNPs. Fully closed genomes of isolates from the stone fruits were used as references to maximize the resolution and to increase our confidence in prophage analysis. Putative prophages were conserved among isolates of each WGS cluster. All serotype IVb-v1 isolates belonged to singleton sequence type 382 (ST382); all but one serotype 1/2b isolate belonged to clonal complex 5. IMPORTANCE: WGS proved to be an excellent tool to assist in the epidemiologic investigation of listeriosis outbreaks. The comparison at the genome level contributed to our understanding of the genetic diversity and variations among isolates involved in an outbreak or isolates associated with food and environmental samples from one facility. Fully closed genomes increased our confidence in the identification and comparison of accessory genomes. The diversity among the outbreak-associated isolates and the inclusion of PFGE matched, but epidemiologically unrelated, isolates demonstrate the high resolution of WGS. The prevalence and enumeration data could contribute to our further understanding of the risk associated with Listeria monocytogenes contamination, especially among high-risk populations. PMID- 27694234 TI - Pendimethalin Nitroreductase Is Responsible for the Initial Pendimethalin Degradation Step in Bacillus subtilis Y3. AB - : Pendimethalin [N-(1-ethylpropyl)-2,6-dinitro-3,4-xylidine] is a selective preemergence dinitroaniline herbicide. Several fungi and bacteria have been reported to degrade pendimethalin, but the enzymes or genes involved in this process have not been characterized. Nitroreduction is the initial degradation and detoxification step for pendimethalin. In this study, a pendimethalin nitroreductase (PNR), responsible for the nitroreduction of pendimethalin, was purified from the pendimethalin-degrading strain Bacillus subtilis Y3. Based on a comparison of its mass fingerprints with all of the deduced proteins from the draft genome of strain Y3, a protein annotated as a nitroreductase was identified, and its corresponding encoding gene was termed pnr PNR was a functional homodimer with a subunit molecular mass of approximately 23 kDa. PNR reduced the C-6 nitro group of the aromatic ring of pendimethalin, yielding 2 nitro-6-amino-N-(1-ethylpropyl)-3,4-xylidine. PNR could also catalyze the nitroreduction of three other major varieties of dinitroaniline herbicides, including butralin, oryzalin, and trifluralin. However, the number of reduced nitro groups was two instead of one, which differed from the nitroreduction of pendimethalin by PNR and which may be due to the symmetry in the chemical structures of the two nitro groups. A detoxification assay revealed that 2-nitro 6-amino-N-(1-ethylpropyl)-3,4-xylidine (PNR-reduced pendimethalin) showed no inhibitory effect on the growth of Saccharomyces cerevisiae BY4741, whereas pendimethalin showed an obvious inhibitory effect on its growth, indicating the detoxification effect of pendimethalin by PNR. Therefore, PNR has potential in pendimethalin detoxification applications. This report describes an enzyme (and corresponding gene) involved in the biodegradation of pendimethalin and dinitroaniline herbicides. IMPORTANCE: Pendimethalin [N-(1-ethylpropyl)-2,6 dinitro-3,4-xylidine] is a widely used selective preemergence dinitroaniline herbicide, and its residue has been frequently detected in the environment. The U.S. Environmental Protection Agency (EPA) has classified pendimethalin as a persistent bioaccumulative toxin. To date, no enzymes or genes involved in pendimethalin biodegradation have been reported. In the present study, the gene pnr, which encodes the nitroreductase PNR, responsible for the nitroreduction of pendimethalin, was cloned from the pendimethalin-degrading strain Bacillus subtilis Y3. PNR could also catalyze the nitroreduction of three other major varieties of dinitroaniline herbicides, including butralin, oryzalin, and trifluralin. The reduction of pendimethalin by PNR might eliminate its toxicity against Saccharomyces cerevisiae BY4741, indicating the application potential of PNR in the detoxification of pendimethalin. PMID- 27694235 TI - Internalization of Heterologous Sugar Transporters by Endogenous alpha-Arrestins in the Yeast Saccharomyces cerevisiae. AB - : When expressed in Saccharomyces cerevisiae using either of two constitutive yeast promoters (PGK1prom and CCW12prom), the transporters CDT-1 and CDT-2 from the filamentous fungus Neurospora crassa are able to catalyze, respectively, active transport and facilitated diffusion of cellobiose (and, for CDT-2, also xylan and its derivatives). In S. cerevisiae, endogenous permeases are removed from the plasma membrane by clathrin-mediated endocytosis and are marked for internalization through ubiquitinylation catalyzed by Rsp5, a HECT class ubiquitin:protein ligase (E3). Recruitment of Rsp5 to specific targets is mediated by a 14-member family of endocytic adaptor proteins, termed alpha arrestins. Here we demonstrate that CDT-1 and CDT-2 are subject to alpha-arrestin mediated endocytosis, that four alpha-arrestins (Rod1, Rog3, Aly1, and Aly2) are primarily responsible for this internalization, that the presence of the transport substrate promotes transporter endocytosis, and that, at least for CDT 2, residues located in its C-terminal cytosolic domain are necessary for its efficient endocytosis. Both alpha-arrestin-deficient cells expressing CDT-2 and otherwise wild-type cells expressing CDT-2 mutants unresponsive to alpha-arrestin driven internalization exhibit an increased level of plasma membrane-localized transporter compared to that of wild-type cells, and they grow, utilize the transport substrate, and generate ethanol anaerobically better than control cells. IMPORTANCE: Ethanolic fermentation of the breakdown products of plant biomass by budding yeast Saccharomyces cerevisiae remains an attractive biofuel source. To achieve this end, genes for heterologous sugar transporters and the requisite enzyme(s) for subsequent metabolism have been successfully expressed in this yeast. For one of the heterologous transporters examined in this study, we found that the amount of this protein residing in the plasma membrane was the rate-limiting factor for utilization of the cognate carbon source (cellobiose) and its conversion to ethanol. PMID- 27694236 TI - Soil Nutrient Depletion Is Associated with the Presence of Burkholderia pseudomallei. AB - : Burkholderia pseudomallei is a soil-dwelling bacterium and the cause of melioidosis, which kills an estimated 89,000 people per year worldwide. Agricultural workers are at high risk of infection due to repeated exposure to the bacterium. Little is known about the soil physicochemical properties associated with the presence or absence of the organism. Here, we evaluated the soil physicochemical properties and presence of B. pseudomallei in 6,100 soil samples collected from 61 rice fields in Thailand. The presence of B. pseudomallei was negatively associated with the proportion of clay, proportion of moisture, level of salinity, percentage of organic matter, presence of cadmium, and nutrient levels (phosphorus, potassium, calcium, magnesium, and iron). The presence of B. pseudomallei was not associated with the level of soil acidity (P = 0.54). In a multivariable logistic regression model, the presence of B. pseudomallei was negatively associated with the percentage of organic matter (odds ratio [OR], 0.06; 95% confidence interval [CI], 0.01 to 0.47; P = 0.007), level of salinity (OR, 0.06; 95% CI, 0.01 to 0.74; P = 0.03), and percentage of soil moisture (OR, 0.81; 95% CI, 0.66 to 1.00; P = 0.05). Our study suggests that B. pseudomallei thrives in rice fields that are nutrient depleted. Some agricultural practices result in a decline in soil nutrients, which may impact the presence and amount of B. pseudomallei bacteria in affected areas. IMPORTANCE: Burkholderia pseudomallei is an environmental Gram-negative bacillus and the cause of melioidosis. Humans acquire the disease following skin inoculation, inhalation, or ingestion of the bacterium in the environment. The presence of B. pseudomallei in soil defines geographic regions where humans and livestock are at risk of melioidosis, yet little is known about the soil properties associated with the presence of the organism. We evaluated the soil properties and presence of B. pseudomallei in 61 rice fields in East, Central, and Northeast Thailand. We demonstrated that the organism was more commonly found in soils with lower levels of organic matter and nutrients, including phosphorus, potassium, calcium, magnesium, and iron. We also demonstrated that crop residue burning after harvest, which can reduce soil nutrients, was not uncommon. Some agricultural practices result in a decline in soil nutrients, which may impact the presence and amount of B. pseudomallei bacteria in affected areas. PMID- 27694237 TI - Ferredoxin:NAD+ Oxidoreductase of Thermoanaerobacterium saccharolyticum and Its Role in Ethanol Formation. AB - : Ferredoxin:NAD+ oxidoreductase (NADH-FNOR) catalyzes the transfer of electrons from reduced ferredoxin to NAD+ This enzyme has been hypothesized to be the main enzyme responsible for ferredoxin oxidization in the NADH-based ethanol pathway in Thermoanaerobacterium saccharolyticum; however, the corresponding gene has not yet been identified. Here, we identified the Tsac_1705 protein as a candidate FNOR based on the homology of its functional domains. We then confirmed its activity in vitro with a ferredoxin-based FNOR assay. To determine its role in metabolism, the tsac_1705 gene was deleted in different strains of T. saccharolyticum In wild-type T. saccharolyticum, deletion of tsac_1705 resulted in a 75% loss of NADH-FNOR activity, which indicated that Tsac_1705 is the main NADH-FNOR in T. saccharolyticum When both NADH- and NADPH-linked FNOR genes were deleted, the ethanol titer decreased and the ratio of ethanol to acetate approached unity, indicative of the absence of FNOR activity. Finally, we tested the effect of heterologous expression of Tsac_1705 in Clostridium thermocellum and found improvements in both the titer and the yield of ethanol. IMPORTANCE: Redox balance plays a crucial role in many metabolic engineering strategies. Ferredoxins are widely used as electron carriers for anaerobic microorganism and plants. This study identified the gene responsible for electron transfer from ferredoxin to NAD+, a key reaction in the ethanol production pathway of this organism and many other metabolic pathways. Identification of this gene is an important step in transferring the ethanol production ability of this organism to other organisms. PMID- 27694238 TI - Phylogenetic Evidence for Ancient and Persistent Environmental Symbiont Reacquisition in Largidae (Hemiptera: Heteroptera). AB - : The insect order Hemiptera, one of the best-studied insect lineages with respect to bacterial symbioses, still contains major branches that lack comprehensive characterization of associated bacterial symbionts. The Pyrrhocoroidea (Largidae [220 species] and Pyrrhocoridae [~300 species]) is a clade of the hemipteran infraorder Pentatomomorpha. Studies on bacterial symbionts of this group have focused on members of Pyrrhocoridae, but recent examination of species of two genera of Largidae demonstrated divergent symbiotic complexes in these putative sister families. We surveyed the associated bacterial diversity of this group using paired-end Illumina sequencing and targeted Sanger sequencing of bacterial 16S rRNA amplicons of 30 pyrrhocoroid taxa, including 17 species of Largidae, in order to determine bacterial associates and the similarity of associated microbial communities among species. We also used molecular data (4,800 bp in 5 loci, for 57 ingroup and 12 outgroup taxa) to infer a phylogeny of the host superfamily, in order to trace the evolution of symbiotic complexes among Pentatomomorpha species. We undertook multiple lines of investigation (i.e., experimental rearing, fluorescence in situ hybridization microscopy, and phylogenetic and coevolutionary analyses) to elucidate potential transmission routes for largid symbionts. We found a prevalent and specific association of Largidae with Burkholderia strains of the plant-associated beneficial and environmental clade, housed in midgut tubules. As in other distantly related Heteroptera, symbiotic bacteria seem to be acquired from the environment every generation. We review the current understanding of symbiotic complexes within Pentatomomorpha and discuss means to further investigate the evolution and function of these symbioses. IMPORTANCE: Obligate symbioses with bacteria are common in insects, particularly Hemiptera, in which various forms of symbiosis occur. However, knowledge regarding symbionts remains incomplete for major hemipteran lineages. Thus, an accurate understanding of how these partnerships evolved and changed over millions of years is not yet achievable. We contribute to our understanding of the evolution of symbiotic complexes in Hemiptera by characterizing bacterial associates of Pyrrhocoroidea, focusing on the family Largidae. Members of Largidae are associated with specific symbiotic Burkholderia strains from a different clade than Burkholderia symbionts in other Burkholderia-associated Hemiptera. Evidence suggests that species of Largidae reacquire specific symbiotic bacteria from the environment every generation, which is a rare strategy for insects, with potentially volatile evolutionary ramifications, but one that must have persisted in Largidae and related lineages since their origin in the Cretaceous Period. PMID- 27694239 TI - Microbial Glucuronoyl Esterases: 10 Years after Discovery. AB - A carbohydrate esterase called glucuronoyl esterase (GE) was discovered 10 years ago in a cellulolytic system of the wood-rotting fungus Schizophyllum commune Genes coding for GEs were subsequently found in a number of microbial genomes, and a new family of carbohydrate esterases (CE15) has been established. The multidomain structures of GEs, together with their catalytic properties on artificial substrates and positive effect on enzymatic saccharification of plant biomass, led to the view that the esterases evolved for hydrolysis of the ester linkages between 4-O-methyl-d-glucuronic acid of plant glucuronoxylans and lignin alcohols, one of the crosslinks in the plant cell walls. This idea of the function of GEs is further supported by the effects of cloning of fungal GEs in plants and by very recently reported evidence for changes in the size of isolated lignin-carbohydrate complexes due to uronic acid de-esterification. These facts make GEs interesting candidates for biotechnological applications in plant biomass processing and genetic modification of plants. This article is a brief summary of current knowledge of these relatively recent and unexplored esterases. PMID- 27694240 TI - Novel Capsular Polysaccharide Loci and New Diagnostic Tools for High-Throughput Capsular Gene Typing in Streptococcus suis. AB - : Streptococcus suis is an important pathogen of pigs and may cause serious disease in humans. Serotyping is an important tool for detection and epidemiological studies of S. suis Thirty-three reference serotypes and nine novel cps loci (NCLs) are recognized in S. suis To gain a better understanding of the prevalence and genetic characteristics of NCLs, we investigated the serotype identity of 486 isolates isolated between 2013 and 2015 in China by capsular gene typing methods. Two hundred seventy-six isolates carried NCLs belonging to 16 groups, 8 of which appear to have not been reported previously. These isolates showed autoagglutination, polyagglutination, or nonagglutination with reference antisera and thus were nonserotypeable. Almost all isolates carrying the unknown NCLs were encapsulated, with various capsular thicknesses, indicating that they are most likely novel serotypes. To simultaneously identify the currently recognized 17 NCLs, an 18-plex detection system using the Luminex xTAG universal array technology was developed. Our data also provide valuable genetic information for monitoring the variations within NCLs by investigating the genetic characteristics of different subtypes within NCLs. IMPORTANCE: Nonserotypeable Streptococcus suis isolates have been reported in many studies, and 9 novel cps loci (NCLs) have already been identified in nonserotypeable isolates. Moreover, novel cps loci are continually being found. The main purpose of this study was to investigate the prevalence and characteristics of NCLs in S. suis isolates recovered between 2013 and 2015 in China. This study provides valuable genetic information for monitoring the variations within NCLs. Meanwhile, a fast and cost-effective 18-plex detection system that can simultaneously identify the currently recognized 17 NCLs was developed in this study. This system will serve as a valuable tool for detecting known and identifying additional novel cps loci among nonserotypeable S. suis isolates. PMID- 27694242 TI - From Anticipatory Corpse to Posthuman God. AB - The essays in this issue of JMP are devoted to critical engagement of my book, The Anticipatory Corpse The essays, for the most part, accept the main thrust of my critique of medicine. The main thrust of the criticism is whether the scope of the critique is too totalizing, and whether the proposed remedy is sufficient. I greatly appreciate these interventions because they allow me this occasion to respond and clarify, and to even further extend the argument of my book. In this response essay, I maintain that the regnant social imaginary of medicine is the regnant social imaginary of our time. It is grounded in a specific ontotheology: where ontology is a power ontology; where material is malleable to the open-ended organization of power and dependent only on working out the efficient mechanisms of its enactment; where ethically it is oriented only to the immanent telos of utility maximization in the short run, and ultimately to some posthuman future in the long run. This ontotheology originates in the anticipatory corpse and is ordered toward some god-like posthuman being. The entire ontotheology finds enactment through the political economy of neoliberalism. This social imaginary constantly works to insulate itself from other social imaginaries through the use of its institutional power, through marginalization, circumscription, or absorption. The modern social imaginary of neoliberal societies marginalizes and politically isolates other social imaginaries, or transforms them into something acceptable to the neoliberal imaginary. Yet, these other social imaginaries could influence the larger social imaginary in novel ways, sometimes through withdrawal and sometimes through challenges. These other practices-again, usually practices ordered according to different ontological and teleological purposes-might serve as a source of renewal and transformation, but only if the practitioners of these other social imaginaries understand the ontotheological powers that they are up against. PMID- 27694241 TI - Interkingdom Cross-Feeding of Ammonium from Marine Methylamine-Degrading Bacteria to the Diatom Phaeodactylum tricornutum. AB - : Methylamines occur ubiquitously in the oceans and can serve as carbon, nitrogen, and energy sources for heterotrophic bacteria from different phylogenetic groups within the marine bacterioplankton. Diatoms, which constitute a large part of the marine phytoplankton, are believed to be incapable of using methylamines as a nitrogen source. As diatoms are typically associated with heterotrophic bacteria, the hypothesis came up that methylotrophic bacteria may provide ammonium to diatoms by degradation of methylamines. This hypothesis was investigated with the diatom Phaeodactylum tricornutum and monomethylamine (MMA) as the substrate. Bacteria supporting photoautotrophic growth of P. tricornutum with MMA as the sole nitrogen source could readily be isolated from seawater. Two strains, Donghicola sp. strain KarMa, which harbored genes for both monomethylamine dehydrogenase and the N methylglutamate pathway, and Methylophaga sp. strain M1, which catalyzed MMA oxidation by MMA dehydrogenase, were selected for further characterization. While strain M1 grew with MMA as the sole substrate, strain KarMa could utilize MMA as a nitrogen source only when, e.g., glucose was provided as a carbon source. With both strains, release of ammonium was detected during MMA utilization. In coculture with P. tricornutum, strain KarMa supported photoautotrophic growth with 2 mM MMA to the same extent as with the equimolar amount of NH4Cl. In coculture with strain M1, photoautotrophic growth of P. tricornutum was also supported, but to a much lower degree than by strain KarMa. This proof-of-principle study with a synthetic microbial community suggests that interkingdom cross-feeding of ammonium from methylamine-degrading bacteria is a contribution to phytoplankton growth which has been overlooked so far. IMPORTANCE: Interactions between diatoms and heterotrophic bacteria are important for marine carbon cycling. In this study, a novel interaction is described. Bacteria able to degrade monomethylamine, which is a ubiquitous organic nitrogen compound in marine environments, can provide ammonium to diatoms. This interkingdom metabolite transfer enables growth under photoautotrophic conditions in coculture, which would not be possible in the respective monocultures. This proof-of-principle study calls attention to a so far overlooked contribution to phytoplankton growth.

AB - OBJECTIVE: Zonal organ allocation system comprises organ procurement by teams within a specific geographical area of each retrieval team. Therefore, in a substantial number of cases organs are retrieved by 'foreign' teams and are sent for transplantation to the implanting centre. The aim of this study was to assess the impact of zonal organ allocation system on early- and long-term outcomes after lung transplantation (LTx). METHODS: Included were 331 consecutive patients who underwent LTx performed at Harefield Hospital between January 2007 and January 2015. Recipients were divided into two groups depending on the organ retrieval team: 204 (61.6%) patients were transplanted using lungs procured by our institutional team (institutional group), whereas 127 (38.4%) organs were retrieved by other teams (external group) from experienced transplant centres in the UK. To exclude selection bias and other confounders, a 1:1 propensity score based matching procedure was performed resulting in a total number of 238 donors and recipients who were well matched for baseline characteristics. The primary end-points were overall survival after LTx and freedom from bronchiolitis obliterans syndrome (BOS). Secondary end-points were perioperative clinical characteristics as well as adverse events that occurred over the follow-up. RESULT: After propensity score matching all donor characteristics and all baseline recipient characteristics were statistically similar between the two groups. In terms of early postoperative results, both groups were statistically comparable. However, there was a trend towards higher incidence of primary graft dysfunction in the external group (P = 0.054). Regarding long-term results with up to 7 years of follow-up, the overall survival also appeared to be poorer in the external group; however, this difference did not reach statistical significance. The freedom from BOS over the long-term follow was significantly poorer in the external group (P = 0.040). CONCLUSION: Despite excellent early outcomes the zonal allocation system might be associated with significantly poorer long-term outcomes in terms of freedom from BOS after bilateral LTx. Further research is needed to find the underlying factors leading to these results. PMID- 27694252 TI - Fifteen years of surgery for acute type A aortic dissection in moderate-to-mild systemic hypothermia?. AB - OBJECTIVE: Surgery for acute type A aortic dissection remains a surgical challenge because of prolonged operative times, bleeding complications, and a considerable risk of neurological morbidity and mortality. The following study investigates the clinical results after surgical treatment for acute type A aortic dissection using selective antegrade cerebral perfusion and moderate-to mild systemic hypothermia (>=28 degrees C). METHODS: Between January 2000 and January 2015, 453 consecutive patients underwent surgical treatment for acute type A aortic dissection at two aortic referral centres in Germany. Patient mean age was 67 +/- 13 years, 298 patients (66%) were male. Selective unilateral or bilateral cerebral perfusion under moderate-to-mild systemic hypothermia was used in all patients. Ascending aortic replacement, hemiarch replacement and total arch replacement was performed in 9 patients (2%), 342 patients (75%) and 102 patients (23%), respectively. Clinical data were prospectively entered into the institutional databases. Mean late follow-up was 6 +/- 3 years and was 98% complete. RESULTS: Cardiopulmonary bypass time totalled 181 +/- 68 min and the myocardial ischaemic time 107 +/- 43 min. Mean duration of selective antegrade cerebral was 46 +/- 23 min. Mean lowest core temperature amounted to 28.8 +/- 0.6 degrees C. Unilateral cerebral perfusion was performed in 298 patients (66%) and bilateral in 155 patients (34%). Mean intensive care unit stay was 5 +/- 7 days. We observed new postoperative permanent neurological deficits in 27 patients (6%) and transient neurological deficits in 31 patients (7%). Thirty-day mortality was 7% (n = 32). Overall survival rate at 5 years was 77 +/- 6%. CONCLUSIONS: Our data suggest that selective antegrade cerebral perfusion in combination with moderate-to-mild systemic hypothermia (>=28 degrees C) can be safely and reproducibly applied to surgery for acute type A aortic dissection and offers sufficient neurological and visceral organ protection.

A comprehensive systematic review and meta-analysis of the options for neoadjuvant therapy for treating oesophageal cancer. AB - Neoadjuvant therapy followed by surgery is a standard treatment for locally advanced oesophageal cancer. However, the roles of neoadjuvant chemoradiotherapy and chemotherapy in treating oesophageal cancer remain controversial. In this comprehensive meta-analysis, we examine the efficacy of adding radiotherapy to neoadjuvant chemotherapy for treating oesophageal cancer as reported in qualified randomized controlled trials (RCTs). We conducted a systematic literature search using PubMed, Embase, Cochrane Library databases, Google Scholar and the American Society of Clinical Oncology database to identify relevant studies up to 31 March 2016. Data including the pathological complete response rate, R0 resection rate and 3-year survival rate were extracted and analysed. Five qualified RCTs were included with a total of 709 patients. Meta-analysis showed that neoadjuvant chemoradiotherapy significantly increases the rates of pathological complete response and R0 resection in patients with oesophageal adenocarcinoma or squamous cell carcinoma (SCC). However, we found a significantly increased 3-year survival rate only in oesophageal SCC patients treated with neoadjuvant chemoradiotherapy compared with neoadjuvant chemotherapy (56.8 and 42.8%, respectively); relative risk (RR): 1.31 [95% confidence interval (CI) 1.10-1.58, P = 0.003]. In oesophageal adenocarcinoma patients, no significant survival benefit of neoadjuvant chemoradiotherapy was found compared with neoadjuvant chemotherapy alone (46.3 and 41.0%, respectively; RR: 1.13, 95% CI 0.88-1.45, P = 0.34). Our meta-analysis adds to the evidence showing that neoadjuvant chemoradiotherapy should be the standard preoperative treatment strategy for locally advanced oesophageal SCC. For oesophageal adenocarcinoma, neoadjuvant chemotherapy alone may be the best preoperative treatment strategy to avoid the risk of adverse effects of radiotherapy.

AB - OBJECTIVE: To characterize the profiles of afferent dysfunction in a cross section of patients with acute vestibular neuritis using tests of otolith and semicircular canal function sensitive to each of the 5 vestibular end organs. METHODS: Forty-three patients fulfilling clinical criteria for acute vestibular neuritis were recruited between 2010 and 2016 and studied within 10 days of symptom onset. Otolith function was evaluated with air-conducted cervical and bone-conducted ocular/vestibular evoked myogenic potentials and the subjective visual horizontal test. Canal-plane video head impulse tests (vHITs) assessed the function of each semicircular canal. Patterns of recovery were investigated in 16 patients retested after a 6- to 12-month follow-up period. RESULTS: Rates of horizontal canal (97.7%), anterior canal (90.7%), and utricular (72.1%) dysfunction were significantly higher than rates of posterior canal (39.5%) and saccular (39.0%) dysfunction (p < 0.008). Twenty-four patients (55.8%) had abnormalities localizing to both vestibular nerve divisions; 18 patients (41.9%) had superior neuritis; and 1 patient (2.3%) had inferior neuritis. A test battery that included horizontal and posterior canal vHIT and the cervical/vestibular evoked myogenic potentials identified superior or inferior neuritis in all patients tested acutely. Eight of 16 patients who were retested at follow-up had recovered a normal vestibular evoked myogenic potential and vHIT profile. CONCLUSIONS: Acute vestibular neuritis most often affects both vestibular nerve divisions. The horizontal vHIT alone identifies superior nerve dysfunction in all patients with vestibular neuritis tested acutely, whereas both cervical/vestibular evoked myogenic potentials and posterior vHIT are necessary for diagnosing inferior vestibular nerve involvement. PMID- 27694258 TI - Introducing the Axon Registry: An opportunity to improve quality of neurologic care. AB - Clinical quality data registries are increasingly popular tools used by providers to improve the quality of clinical care and satisfy growing numbers of regulatory and reporting requirements. Specialty societies use registries to provide value to their members and guide improvements in care at the population level. In this article, we outline the rationale, structure, function, and challenges related to the American Academy of Neurology's development of its own clinical quality data registry: the Axon Registry. PMID- 27694257 TI - Plasma tau in Alzheimer disease. AB - OBJECTIVE: To test whether plasma tau is altered in Alzheimer disease (AD) and whether it is related to changes in cognition, CSF biomarkers of AD pathology (including beta-amyloid [Abeta] and tau), brain atrophy, and brain metabolism. METHODS: This was a study of plasma tau in prospectively followed patients with AD (n = 179), patients with mild cognitive impairment (n = 195), and cognitive healthy controls (n = 189) from the Alzheimer's Disease Neuroimaging Initiative (ADNI) and cross-sectionally studied patients with AD (n = 61), mild cognitive impairment (n = 212), and subjective cognitive decline (n = 174) and controls (n = 274) from the Biomarkers for Identifying Neurodegenerative Disorders Early and Reliably (BioFINDER) study at Lund University, Sweden. A total of 1284 participants were studied. Associations were tested between plasma tau and diagnosis, CSF biomarkers, MRI measures, 18fluorodeoxyglucose-PET, and cognition. RESULTS: Higher plasma tau was associated with AD dementia, higher CSF tau, and lower CSF Abeta42, but the correlations were weak and differed between ADNI and BioFINDER. Longitudinal analysis in ADNI showed significant associations between plasma tau and worse cognition, more atrophy, and more hypometabolism during follow-up. CONCLUSIONS: Plasma tau partly reflects AD pathology, but the overlap between normal aging and AD is large, especially in patients without dementia. Despite group-level differences, these results do not support plasma tau as an AD biomarker in individual people. Future studies may test longitudinal plasma tau measurements in AD.

PMID- 27694260 TI - Whole-exome sequencing identifies a missense mutation in hnRNPA1 in a family with flail arm ALS. AB - OBJECTIVE: To identify the disease-causing gene of a family with upper limb predominant, slowly progressive amyotrophic lateral sclerosis (ALS), which was diagnosed as flail arm syndrome (FAS). METHODS: After causation of 24 known ALS genes was excluded by targeted next-generation sequencing, whole-exome sequencing was applied in the FAS family. Cellular localization of mutant hnRNPA1 was examined in transfected HeLa cells. An additional 251 Chinese patients with ALS (including 7 sporadic FAS) underwent mutation screening of hnRNPA1. RESULTS: We detected a novel missense mutation in hnRNPA1, c.862/1018C>T (p.P288S/P340S), which cosegregated with disease in the FAS family. The residue is highly conserved across species and exists in the encoded PY nuclear localization signal of hnRNPA1 protein. Mutant hnRNPA1 showed altered intracellular localization, resulting in formation of cytoplasmic inclusions that colocalized with stress granules in transfected cells. Further mutation screening of hnRNPA1 in additional patients with FAS and typical ALS detected 2 rare variants with unknown significance. These variants lie in the prion-like domain of hnRNPA1 long isoform, which was detected exclusively in the CNS. CONCLUSIONS: Our results suggest that hnRNPA1 is the causative gene in the family with flail arm ALS. This further expanded the disease phenotype of hnRNPA1 mutations. PMID- 27694262 TI - Quality of life at 6 months in the Idiopathic Intracranial Hypertension Treatment Trial. AB - OBJECTIVE: To examine the changes in vision-specific and overall health-related quality of life (QOL) at 6 months in participants with idiopathic intracranial hypertension (IIH) and mild visual loss enrolled in the Idiopathic Intracranial Hypertension Treatment Trial (IIHTT) and to determine the signs and symptoms of IIH that mediate the effect of acetazolamide on QOL. METHODS: We assessed QOL using the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25), the 10-Item NEI-VFQ-25 Neuro-Ophthalmic Supplement, and the 36-Item Short Form Health Survey (SF-36). We examined associations among changes in QOL measures over 6 months, treatment status, and changes in signs and symptoms using linear and structural equation models. RESULTS: Among the 165 participants with IIH (86 randomized to acetazolamide, 79 to placebo), beneficial effects of acetazolamide were seen on all QOL scales evaluated, as well as on the Near Activities (5.60 points, p = 0.03), Social Functioning (3.85 points, p = 0.04), and Mental Health (9.82, p = 0.04) subscales of the NEI-VFQ-25. Positive acetazolamide-related effects on QOL appeared to be primarily mediated by improvements in visual field, neck pain, pulsatile tinnitus, and dizziness/vertigo that outweighed the side effects of acetazolamide. CONCLUSIONS: The marked reductions in baseline QOL seen among patients with mild visual loss from IIH are improved by treatment with acetazolamide. When combined with acetazolamide-associated improvements in visual field and other aspects of IIH, our findings with respect to QOL provide further support from the IIHTT in favor of acetazolamide to augment a dietary intervention in the treatment of IIH with mild visual loss (clinicaltrials.gov: NCT01003639). PMID- 27694263 TI - How long should we wait to start oral anticoagulation after cardioembolic stroke? PMID- 27694264 TI - Cluster headache and depression. AB - OBJECTIVE: As cluster headache (CH) is often referred to as "suicide headache," we wanted to assess the prevalence of depression in CH patients, and to investigate determinants of depression such as sleep disturbances. METHODS: In a cross-sectional, web-based, validated questionnaire study among 462 well-defined CH patients and 177 controls, we diagnosed CH according to the ICHD-III. We assessed depression using the Hospital Anxiety and Depression Scale (HADS-D) and the Center for Epidemiologic Studies Depression scale (CES-D) with supplementary questions to assess lifetime depression. Data were analyzed with logistic and linear regression models. RESULTS: Lifetime depression showed almost 3 times higher odds in CH patients (n = 462) than controls (n = 177) (odds ratio 2.77; 95% confidence interval 1.70-4.51). Chronic (n = 67) vs episodic (n = 394) patients had a higher prevalence of lifetime depression and more sleeping problems. Current depression was associated with having active attacks (last attack <1 month) (adjusted p = 0.02), but no effect remained after correction for sleep disturbances. CONCLUSIONS: CH is associated with an almost 3 times increased odds of lifetime depression. Current depression is highly prevalent in patients with active disease, in part related to sleep disturbances due to current nocturnal attacks. PMID- 27694265 TI - Prediction of 3-year clinical course in CADASIL. AB - OBJECTIVE: To obtain simple models predicting disease evolution at 3 years for a given patient with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). METHODS: Based on data obtained in a prospective study of 236 patients, we built and validated models predicting, at the individual level, 3-year changes in Mini-Mental State Examination (MMSE), Mattis Dementia Rating Scale (MDRS), Trail Making Test version B (TMTB), and modified Rankin Scale (mRS). These models were based on different sets of predictors obtained at baseline, including either clinical data (epidemiologic data and cardiovascular risk factors) or clinical data and quantitative MRI markers (volume of lacunes [LLV], volume of white matter hyperintensities, normalized brain volume [BPF], number of microbleeds). The Bayesian information criterion (BIC) and the coefficient of determination (R2) were used to determine models with the highest predictive ability and the lowest numbers of predictors. RESULTS: We obtained validated models with a demonstrated ability to predict, for a given patient, 3-year changes in MMSE, MDRS, TMTB, and mRS (R2 on independent samples: 0.22, 0.12, 0.09, and 0.17, respectively). In all cases, the best models according to R2 and BIC values included only the baseline values of the outcome, of BPF, and of LLV. Inclusion of other potential predictors always led to a loss of generalizability. CONCLUSIONS: The prediction of 3-year changes in MMSE, MDRS, TMTB, and mRS for a given patient with CADASIL can be obtained using simple models relying only on the initial values of the considered score, BPF, and LLV. PMID- 27694266 TI - Early start of DOAC after ischemic stroke: Risk of intracranial hemorrhage and recurrent events. AB - OBJECTIVE: In patients with recent acute ischemic stroke (AIS) and atrial fibrillation, we assessed the starting time of direct, non-vitamin K antagonist oral anticoagulants (DOACs) for secondary prevention, the rate of intracranial hemorrhage (ICH), and recurrent ischemic events during follow-up. METHODS: We included consecutive patients with nonvalvular atrial fibrillation admitted to our hospital for AIS or TIA (index event) who received secondary prophylaxis with DOAC or vitamin K antagonists (VKAs). Follow-up was at least 3 months. In the primary analysis, we compared rates of ICH and recurrent ischemic events (AIS or TIA) between patients with early (<=7 days since event; DOACearly) and those with late (>7 days, DOAClate) start of DOAC. RESULTS: Two hundred four patients were included (median age 79 years, 89% AIS) and total follow-up time was 78.25 patient-years. One hundred fifty-five patients received DOAC with a median delay of 5 days after the index event (interquartile range 3-11) and 49 received VKA. DOAC was started early in 100 patients (65%). We observed one ICH (1.3%/y) and 6 recurrent AIS (7.7%/y). The ICH occurred in a patient taking VKA. No significant difference in the rate of recurrent AIS between DOACearly (5.1%/y) and DOAClate (9.3%/y, p = 0.53) was observed. CONCLUSIONS: Even if DOACs are often started early after an index event, the risk of ICH appears to be low. Among all patients receiving anticoagulation, the rate of recurrent events was 6 times higher than the rate of ICH. PMID- 27694267 TI - MRI-negative temporal lobe epilepsy: A network disorder of neocortical connectivity. AB - OBJECTIVE: To define the functional network changes that characterize MRI negative temporal lobe epilepsy (TLE) and TLE with hippocampal sclerosis (HS TLE). METHODS: We studied 36 patients with medically refractory unilateral TLE, having either a normal clinical MRI (n = 18) or unilateral hippocampal sclerosis (n = 18). Patients were compared to healthy controls of equivalent age and sex (n = 27). Functional connectivity in 10 minutes of task-free functional MRI was assessed using a voxel-resolution graph theoretic analysis, using the metrics of degree, clustering coefficient, eigenvector, and betweenness centrality. Significant clusters were further explored with a seed-based analysis. RESULTS: MRI-negative TLE showed decreased connectivity at the ipsilateral superior and middle temporal gyri compared to controls (decreased eigenvector centrality). No functional abnormality was detected within mesial temporal structures. In contrast, HS-TLE showed increased connectivity within the affected hippocampus and anterior thalamus (increased clustering coefficient) and decreased connectivity of the ventromesial prefrontal cortex (decreased betweenness centrality). Using the detected clusters as seed regions revealed decreased connectivity from the sclerotic hippocampus to both the contralateral temporal lobe and regions of the default mode network. CONCLUSION: MRI-negative TLE is associated with impaired interictal connectivity of the temporal neocortex, lateralized to the epileptic side. HS-TLE shows a different pattern, with functional segregation of the sclerotic hippocampus and impairment of its long range connectivity. This suggests that MRI-negative TLE is not merely a subtle version of hippocampal sclerosis, but is rather a separate condition that involves distinct brain networks. PMID- 27694269 TI - Distal Metatarsal Osteotomy for Moderate to Severe Hallux Valgus. AB - : Hallux valgus is the most common disorder of the hallux and often results in pain, functional disability, and impaired gait patterns. The goals of surgical management are to correct the deformity while improving patients' pain and function. Traditional treatment of moderate to severe hallux valgus deformities consist of proximal osteotomy and/or arthrodesis given their powerful corrective ability. Despite their corrective power, proximal osteotomies are more technically demanding, have a higher rate of complications, and require a more restricted post-operative recovery. We present an alternative technique for the treatment of moderate to severe hallux valgus. With this operation, a single distal medial incision is utilized to create a chevron osteotomy and lateral release. This procedure can achieve and maintain the desired correction and outcome without the need for a protracted recovery period. LEVEL OF EVIDENCE: Level V, expert opinion. PMID- 27694268 TI - Cortical superficial siderosis predicts early recurrent lobar hemorrhage. AB - OBJECTIVE: To identify predictors of early lobar intracerebral hemorrhage (ICH) recurrence, defined as a new ICH within 6 months of the index event, in patients with cerebral amyloid angiopathy (CAA). METHODS: Participants were consecutive survivors (age >=55 years) of spontaneous symptomatic probable or possible CAA related lobar ICH according to the Boston criteria, drawn from an ongoing single center cohort study. Neuroimaging markers ascertained in CT or MRI included focal (<=3 sulci) or disseminated (>3 sulci) cortical superficial siderosis (cSS), acute convexity subarachnoid hemorrhage (cSAH), cerebral microbleeds, white matter hyperintensities burden and location, and baseline ICH volume. Participants were followed prospectively for recurrent symptomatic ICH. Cox proportional hazards models were used to identify predictors of early recurrent ICH adjusting for potential confounders. RESULTS: A total of 292 patients were enrolled. Twenty-one patients (7%) had early recurrent ICH. Of these, 24% had disseminated cSS on MRI and 19% had cSAH on CT scan. In univariable analysis, the presence of disseminated cSS, cSAH, and history of previous ICH were predictors of early recurrent ICH (p < 0.05 for all comparisons). After adjusting for age and history of previous ICH, disseminated cSS on MRI and cSAH on CT were independent predictors of early recurrent ICH (hazard ratio [HR] 3.92, 95% confidence interval [CI] 1.38-11.17, p = 0.011, and HR 3.48, 95% CI 1.13-10.73, p = 0.030, respectively). CONCLUSIONS: Disseminated cSS on MRI and cSAH on CT are independent imaging markers of increased risk for early recurrent ICH. These markers may provide additional insights into the mechanisms of ICH recurrence in patients with CAA.

AB - BACKGROUND: The benefit of cricoid pressure during tracheal intubation is still debated and, due to its potential negative impact on laryngeal views, its routine use is questioned. The goal of this study was to estimate its impact on laryngeal view. METHODS: All patients intubated in the prehospital setting were included. Three different propensity score (PS) models were used and compared in terms of the balance achieved between those patients who received cricoid pressure and those who did not. The PS model that optimised the balance was retained in order to estimate the relationship between cricoid pressure and the following outcomes: difficult laryngoscopy, intubation-related complications and difficult intubation. RESULTS: Among the 1195 patients included, 499 (41.7%) received cricoid pressure. The optimal PS included seven variables (cardiac arrest, altered neurological status, shock, respiratory distress, gender, obesity, patient's position). After PS matching, no significant risk difference (RD) in the rate of difficult laryngoscopy was found between the patients who received cricoid pressure and those who did not (RD=0.001, 95% CI -0.07 to 0.08, p=0.50). No significant difference was found in terms of difficult intubation (RD=0.06, 95% CI -0.13 to 0.25, p=0.28) and in terms of prevalence of complications, except for airway trauma that were more frequent in cricoid pressure group (RD=0.03, 95% CI 0.002 to 0.05, p=0.01). CONCLUSIONS: No significant relationship was found between the use of cricoid pressure for prehospital intubation and difficult laryngoscopy. Cricoid pressure was found to be associated with more airway trauma. This finding could question its routine use. PMID- 27694276 TI - Dynamic contrast-enhanced MRI measurement of renal function in healthy participants. AB - Background High repeatability, accuracy, and precision for renal function measurements need to be achieved to establish renal dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) as a clinically useful diagnostic tool. Purpose To investigate the repeatability, accuracy, and precision of DCE-MRI measured renal perfusion and glomerular filtration rate (GFR) using iohexol-GFR as the reference method. Material and Methods Twenty healthy non-smoking volunteers underwent repeated DCE-MRI and an iohexol-GFR within a period of 10 days. Single-kidney (SK) MRI measurements of perfusion (blood flow, Fb) and filtration (GFR) were derived from parenchymal intensity time curves fitted to a two-compartment filtration model. The repeatability of the SK-MRI measurements was assessed using coefficient of variation (CV). Using iohexol-GFR as reference method, the accuracy of total MR-GFR was determined by mean difference (MD) and precision by limits of agreement (LoA). Results SK-Fb (MR1, 345 +/- 84; MR2, 371 +/- 103 mL/100 mL/min) and SK-GFR (MR1, 52 +/- 14; MR2, 54 +/- 10 mL/min/1.73 m2) measurements achieved a repeatability (CV) in the range of 15-22%. With reference to iohexol-GFR, MR-GFR was determined with a low mean difference but high LoA (MR1, MD 1.5 mL/min/1.73 m2, LoA [-42, 45]; MR2, MD 6.1 mL/min/1.73 m2, LoA [-26, 38]). Eighty percent and 90% of MR-GFR measurements were determined within +/- 30% of the iohexol-GFR for MR1 and MR2, respectively. Conclusion Good repeatability of SK-MRI measurements and good agreement between MR-GFR and iohexol-GFR provide a high clinical potential of DCE-MRI for renal function assessment. A moderate precision in MR-derived estimates indicates that the method cannot yet be used in clinical routine. PMID- 27694277 TI - A Longitudinal Study of Maternal and Child Internalizing Symptoms Predicting Early Adolescent Emotional Eating. AB - Objective: To examine maternal and child internalizing symptoms as predictors of early adolescent emotional eating in a longitudinal framework spanning three critical developmental periods (preschool, elementary school, and early adolescence). Methods: Participants were 170 children recruited at preschool age for a longitudinal study. When children were 5.25 years, their mothers completed ratings of their own internalizing symptoms. During the spring of 4th grade, children completed measures of internalizing symptoms. In early adolescence, youth completed a measure of emotional eating. Results: Maternal and child internalizing symptoms predicted adolescent emotional eating. The results indicated that child psychopathology moderated the association between maternal psychopathology (except for maternal anxiety) and early adolescent emotional eating. There was no evidence of mediation. Conclusions: Pediatric psychologists are encouraged to provide early screening of, and interventions for, maternal and child internalizing symptoms to prevent children's emotional eating. PMID- 27694278 TI - Staging of Fatty Liver Diseases Based on Hierarchical Classification and Feature Fusion for Back-Scan-Converted Ultrasound Images. AB - Fatty liver disease is progressive and may not cause any symptoms at early stages. This disease is potentially fatal and can cause liver cancer in severe stages. Therefore, diagnosing and staging fatty liver disease in early stages is necessary. In this paper, a novel method is presented to classify normal and fatty liver, as well as discriminate three stages of fatty liver in ultrasound images. This study is performed with 129 subjects including 28 normal, 47 steatosis, 42 fibrosis, and 12 cirrhosis images. The proposed approach uses back scan conversion of ultrasound sector images and is based on a hierarchical classification. The proposed algorithm is performed in two parts. The first part selects the optimum regions of interest from the focal zone of the back-scan converted ultrasound images. In the second part, discrimination between normal and fatty liver is performed and then steatosis, fibrosis, and cirrhosis are classified in a hierarchical basis. The wavelet packet transform and gray-level co-occurrence matrix are used to obtain a number of statistical features. A support vector machine classifier is used to discriminate between normal and fatty liver, and stage fatty cases. The results of the proposed scheme clearly illustrate the efficiency of this system with overall accuracy of 94.91% and also specificity of more than 90%. PMID- 27694279 TI - The use of mobile applications to support self-management for people with asthma: a systematic review of controlled studies to identify features associated with clinical effectiveness and adherence. AB - Objectives: Telehealth is promoted as a strategy to support self-management of long-term conditions. The aim of this systematic review is to identify which information and communication technology features implemented in mobile apps to support asthma self-management are associated with adoption, adherence to usage, and clinical effectiveness. Methods: We systematically searched 9 databases, scanned reference lists, and undertook manual searches (January 2000 to April 2016). We include randomized controlled trials (RCTs) and quasiexperimental studies with adults. All eligible papers were assessed for quality, and we extracted data on the features included, health-related outcomes (asthma control, exacerbation rate), process/intermediate outcomes (adherence to monitoring or treatment, self-efficacy), and level of adoption of and adherence to use of technology. Meta-analysis and narrative synthesis were used. Results: We included 12 RCTs employing a range of technologies. A meta-analysis (n = 3) showed improved asthma control (mean difference -0.25 [95% CI, -0.37 to -0.12]). Included studies incorporated 10 features grouped into 7 categories (education, monitoring/electronic diary, action plans, medication reminders/prompts, facilitating professional support, raising patient awareness of asthma control, and decision support for professionals). The most successful interventions included multiple features, but effects on health-related outcomes were inconsistent. No studies explicitly reported adoption of and adherence to the technology system. Conclusion: Meta-analysis of data from 3 trials showed improved asthma control, though overall the clinical effectiveness of apps, typically incorporating multiple features, varied. Further studies are needed to identify the features that are associated with adoption of and adherence to use of the mobile app and those that improve health outcomes. PMID- 27694280 TI - Patterns of Comorbidity Among Girls With ADHD: A Meta-analysis. AB - CONTEXT: Although children with attention-deficit/hyperactivity disorder (ADHD) are at elevated risk for comorbid psychopathology, the clinical correlates of ADHD in girls are far less understood relative to boys, despite ADHD being one of the most common childhood disorders in girls. OBJECTIVE: To meta-analytically summarize rates of comorbid internalizing (anxiety, depression) and externalizing (oppositional defiant disorder [ODD], conduct disorder [CD]) psychopathology among girls with and without ADHD. DATA SOURCES: Literature searches (PubMed, Google Scholar) identified published studies examining comorbid psychopathology in girls with and without ADHD. STUDY SELECTION: Eighteen studies (1997 participants) met inclusion criteria and had sufficient data for the meta analysis. DATA EXTRACTION: Odds ratios for each comorbid disorder were calculated from available data. Demographic (eg, age, race/ethnicity) and study characteristics (eg, referral source, diagnostic method) were also coded. RESULTS: Compared with girls without ADHD, girls with ADHD were significantly more likely to meet Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for each comorbid disorder assessed. Relative odds were higher for externalizing (ODD: 5.6*; CD: 9.4*) relative to internalizing disorders (anxiety: 3.2*; depression: 4.2*). Meta-regression revealed larger effect sizes of ADHD on anxiety for studies using multiple diagnostic methods, featuring younger children, and including clinic-referred (versus community-referred) girls; the effect of ADHD on ODD varied based on diagnostic informant. LIMITATIONS: Findings were derived from cross-sectional studies, precluding causal inferences. CONCLUSIONS: Girls with ADHD frequently exhibit comorbid externalizing and internalizing disorders. We discuss future research priorities and consider intervention implications for ADHD and comorbid psychopathology in girls. PMID- 27694281 TI - Interventions to Improve Patient Safety During Intubation in the Neonatal Intensive Care Unit. AB - OBJECTIVE: To improve patient safety in our NICU by decreasing the incidence of intubation-associated adverse events (AEs). METHODS: We sequentially implemented and tested 3 interventions: standardized checklist for intubation, premedication algorithm, and computerized provider order entry set for intubation. We compared baseline data collected over 10 months (period 1) with data collected over a 10 month intervention and sustainment period (period 2). Outcomes were the percentage of intubations containing any prospectively defined AE and intubations with bradycardia or hypoxemia. We followed process measures for each intervention. We used risk ratios (RRs) and statistical process control methods in a times series design to assess differences between the 2 periods. RESULTS: AEs occurred in 126/273 (46%) intubations during period 1 and 85/236 (36%) intubations during period 2 (RR = 0.78; 95% confidence interval [CI], 0.63-0.97). Significantly fewer intubations with bradycardia (24.2% vs 9.3%, RR = 0.39; 95% CI, 0.25-0.61) and hypoxemia (44.3% vs 33.1%, RR = 0.75, 95% CI 0.6-0.93) occurred during period 2. Using statistical process control methods, we identified 2 cases of special cause variation with a sustained decrease in AEs and bradycardia after implementation of our checklist. All process measures increased reflecting sustained improvement throughout data collection. CONCLUSIONS: Our interventions resulted in a 10% absolute reduction in AEs that was sustained. Implementation of a standardized checklist for intubation made the greatest impact, with reductions in both AEs and bradycardia. PMID- 27694282 TI - The effects of a 50-Hz magnetic field on the cardiovascular system in rats. AB - A 50-Hz magnetic field (MF) is a potential health-risk factor. Its effects on the cardiovascular system have not been fully investigated. This study was conducted to explore the effects of long-term exposure to a 50-Hz MF on the cardiovascular system. In the study, an exposure system was constructed, and the distribution of the 50-Hz MF was determined. Sixty-four Sprague-Dawley (SD) rats were exposed to a 50-Hz MF at 100 MUT for 24 weeks, 20 h per day, while another 64 rats were sham exposed. During the exposure, blood pressure was measured every 4 weeks. After 24 weeks, echocardiography, cardiac catheterization and electrocardiography were performed. Moreover, heart and body weight were recorded, and haematoxylin-eosin staining and real-time PCR were conducted. The results showed that compared with the sham group, exposure to a 50-Hz MF did not exert any effects on blood pressure, pulse rate, heart rate or cardiac rhythm. Furthermore, echocardiography and cardiac catheterization showed that there were no significant differences in the cardiac morphology or haemodynamics. In addition, histopathological examination showed that exposure to a 50-Hz MF had no effects on the structure of the heart. Finally, expression of the cardiac hypertrophy-related genes did not show any significant differences between the 50-Hz MF exposure group and the sham group. Taken together, in SD rats, exposure to a 50-Hz/100 MUT MF for 24 weeks did not show any obvious effects on the cardiovascular system. PMID- 27694283 TI - No adverse effects detected for simultaneous whole-body exposure to multiple frequency radiofrequency electromagnetic fields for rats in the intrauterine and pre- and post-weaning periods. AB - In everyday life, people are exposed to radiofrequency (RF) electromagnetic fields (EMFs) with multiple frequencies. To evaluate the possible adverse effects of multifrequency RF EMFs, we performed an experiment in which pregnant rats and their delivered offspring were simultaneously exposed to eight different communication signal EMFs (two of 800 MHz band, two of 2 GHz band, one of 2.4 GHz band, two of 2.5 GHz band and one of 5.2 GHz band). Thirty six pregnant Sprague Dawley (SD) 10-week-old rats were divided into three groups of 12 rats: one control (sham exposure) group and two experimental (low- and high-level RF EMF exposure) groups. The whole body of the mother rats was exposed to the RF EMFs for 20 h per day from Gestational Day 7 to weaning, and F1 offspring rats (46-48 F1 pups per group) were then exposed up to 6 weeks of age also for 20 h per day. The parameters evaluated included the growth, gestational condition and organ weights of the dams; the survival rates, development, growth, physical and functional development, memory function, and reproductive ability of the F1 offspring; and the embryotoxicity and teratogenicity in the F2 rats. No abnormal findings were observed in the dams or F1 offspring exposed to the RF EMFs or to the F2 offspring for any of the parameters evaluated. Thus, under the conditions of the present experiment, simultaneous whole-body exposure to eight different communication signal EMFs at frequencies between 800 MHz and 5.2 GHz did not show any adverse effects on pregnancy or on the development of rats. PMID- 27694284 TI - Biochemical, Physiological and Psychological Changes During Endurance Exercise in People With Type 1 Diabetes. AB - BACKGROUND: Increasing numbers of people with diabetes are adopting exercise programs. Fear of hypoglycemia, hypoglycemia itself, and injuries are major issues for many people with diabetes undertaking physical activity. The purpose of this study was to investigate the effects of type 1 diabetes mellitus on the risk of hypoglycemia, glycemic variability, exercise performance, changes in body composition, changes in insulin dosage, and psychosocial well-being during a multiday endurance exercise event. METHODS: Eleven participants (7 with type 1 diabetes, 4 with normal glucose tolerance) undertook a 15-day, 2300 km cycling tour from Barcelona to Vienna. Data were prospectively collected using bike computers, continuous glucose monitors, body composition analyzers, and mood questionnaires. RESULTS: Mean blood glucose in riders with and without diabetes significantly reduced as the event progressed. Glycemic variability and time spent in hypoglycemia did not change throughout the ride for either set of riders. Riders with diabetes in the lowest quartile of sensor glucose values had significantly reduced power output. Percentage body fat also significantly fell. Hypo- and hyperglycemia provoked feelings of anxiety and worry. CONCLUSIONS: This is the first study to describe a real-time endurance event in type 1 diabetes, and provides important new data that cannot be studied in laboratory conditions. Hypoglycemia continues to occurs in spite of peer support and large reductions in insulin dose. Glycemic variability is shown as a potential barrier to participation in physical activity through effects on mood and psychological well being. PMID- 27694286 TI - Reliability, Validity, and Feasibility of Direct Elicitation of Children's Preferences for Health States. AB - BACKGROUND: Children's preferences for health states represent an important perspective when comparing the value of alternative health care interventions related to pediatric medicine, and are fundamental to comparative effectiveness research. However, there is debate over whether these preference data can be collected and used. PURPOSE: The purpose of this study was to establish psychometric properties of eliciting preferences for health states from children using direct methods. DATA SOURCES: Ovid Medline, PsycINFO, Scopus, EconLit. STUDY SELECTION: English studies, published after 1990, were identified using Medical Subject Headings or keywords. Results were reviewed to confirm that the study was based on: 1) a sample of children, and 2) preferences for health states. DATA EXTRACTION: Standardized data collection forms were used to record the preference elicitation method used, and any reported evidence regarding the validity, reliability, or feasibility of the method. DATA SYNTHESIS: Twenty-six studies were ultimately included in the analysis. The standard gamble and time tradeoff were the most commonly reported direct preference elicitation methods. Seven studies reported validity, four reported reliability, and nine reported feasibility. Of the validity reports, construct validity was assessed most often. Reliability reports typically involved interclass correlation coefficient. For feasibility, four studies reported completion rates. LIMITATIONS: The search was limited to four databases and restricted to English studies published after 1990. Only evidence available in published studies were considered; measurement properties may have been tested in pilot or pre-studies but were not published, and are not included in this review. CONCLUSION: The few studies found through this systematic review demonstrate that there is little empirical evidence on which to judge the use of direct preference elicitation methods with children regarding health states. PMID- 27694287 TI - Understanding Supportive Care Factors Among African American Breast Cancer Survivors. AB - INTRODUCTION: Comprehensive breast cancer care includes not only diagnosis, staging, and treatment of cancer but also assessment and management of the physical, psychological, social, and informational needs, collectively known as supportive care. Several studies have documented the importance of addressing supportive care factors among breast cancer survivors. However, there appears to be a paucity of research concerning African American breast cancer survivors (AABCS). Therefore, the purpose of this study was to describe and understand the patient-centered supportive care factors among self-identified AABCS. METHOD: Using a qualitative descriptive approach, an open-ended question explored supportive care factors that were used by N = 155 AABCS. RESULTS: Four supportive care factors were identified: faith, supportive structures, optimism, and access to information. DISCUSSION: An understanding of these factors might facilitate discussion between survivors and the health care team. The resultant effect could also inform and promote the delivery of culturally specific health care to address the supportive care needs among these women.

AB - Liver diseases are the fourth leading cause of mortality among adults in the United States. Patients with chronic liver diseases such as viral hepatitis, fibrosis, and cirrhosis have significantly higher risks of developing hepatocellular carcinoma (HCC). With a dismal five-year survival rate of 11%, HCC is the third most common cause of cancer-related deaths worldwide. Regardless of the underlying cause, late presentation and a lack of effective therapy are the major impediments for successful treatment of HCC. Therefore, there is a considerable interest in developing new strategies for the prevention and treatment of chronic liver diseases at the early stages. Cancer stem cells (CSCs), a small cell subpopulation in a tumor, exhibit unlimited self-renewal and differentiation capacity. These cells are believed to play pivotal roles in the initiation, growth, metastasis, and drug-resistance of tumors. In this review, we will briefly discuss pivotal roles of the CSC marker doublecortin-like kinase 1 (DCLK1) in hepatic tumorigenesis. Recent evidence suggests that anti-DCLK1 strategies hold promising clinical potential for the treatment of cancers of the liver, pancreas, and colon. PMID- 27694289 TI - Preparing Dental Students and Residents to Overcome Internal and External Barriers to Evidence-Based Practice. AB - In recent years, evidence-based dentistry has become the ideal for research, academia, and clinical practice. However, barriers to implementation are many, including the complexity of interpreting conflicting evidence as well as difficulties in accessing it. Furthermore, many proponents of evidence-based care seem to assume that good evidence consistently exists and that clinicians can and will objectively evaluate data so as to apply the best evidence to individual patients' needs. The authors argue that these shortcomings may mislead many clinicians and that students should be adequately prepared to cope with some of the more complex issues surrounding evidence-based practice. Cognitive biases and heuristics shape every aspect of our lives, including our professional behavior. This article reviews literature from medicine, psychology, and behavioral economics to explore the barriers to implementing evidence-based dentistry. Internal factors include biases that affect clinical decision making: hindsight bias, optimism bias, survivor bias, and blind-spot bias. External factors include publication bias, corporate bias, and lack of transparency that may skew the available evidence in the peer-reviewed literature. Raising awareness of how these biases exert subtle influence on decision making and patient care can lead to a more nuanced discussion of addressing and overcoming barriers to evidence based practice. PMID- 27694290 TI - Improving a Dental School's Clinic Operations Using Lean Process Improvement. AB - The term "lean production," also known as "Lean," describes a process of operations management pioneered at the Toyota Motor Company that contributed significantly to the success of the company. Although developed by Toyota, the Lean process has been implemented at many other organizations, including those in health care, and should be considered by dental schools in evaluating their clinical operations. Lean combines engineering principles with operations management and improvement tools to optimize business and operating processes. One of the core concepts is relentless elimination of waste (non-value-added components of a process). Another key concept is utilization of individuals closest to the actual work to analyze and improve the process. When the medical center of the University of Kentucky adopted the Lean process for improving clinical operations, members of the College of Dentistry trained in the process applied the techniques to improve inefficient operations at the Walk-In Dental Clinic. The purpose of this project was to reduce patients' average in-the-door to-out-the-door time from over four hours to three hours within 90 days. Achievement of this goal was realized by streamlining patient flow and strategically relocating key phases of the process. This initiative resulted in patient benefits such as shortening average in-the-door-to-out-the-door time by over an hour, improving satisfaction by 21%, and reducing negative comments by 24%, as well as providing opportunity to implement the electronic health record, improving teamwork, and enhancing educational experiences for students. These benefits were achieved while maintaining high-quality patient care with zero adverse outcomes during and two years following the process improvement project. PMID- 27694292 TI - Community-Based Dental Education Models: An Analysis of Current Practices at U.S. Dental Schools. AB - Community-based dental education (CBDE) enhances students' clinical expertise, improves their cultural competence, increases access to care, and fosters community engagement. As emphasis on CBDE has increased over the last decades, the aim of this survey study was to determine how CBDE is currently being implemented in U.S. dental schools. The study used a 20-item, author-designed survey emailed in April to August 2015 to 60 of the 65 U.S. dental schools, excluding those that had been recently established. Of the 60 schools, representatives of 33 responded, resulting in a 55% response rate: 70% public and 30% private. These respondents reported that the extramural sites being used the most were community clinics (90.9%), Federally Qualified Health Clinics (66.7%), public health clinics (54.5%), and Indian Health Service clinics (42.4%). The majority of responding schools (63.6%) had ten or more sites available for rotations, and the rotation lengths were 1-2 weeks (29%), 2-4 weeks (25%), 4-6 weeks (29%), 6-8 weeks (3.2%), and 8-10 weeks (12.9%). Most of the respondents (78.8%) reported that their students were unable to be assessed for clinical competencies at external clinical sites, but roughly half allowed students to receive clinical credit. After students completed their rotations, the majority of the respondents (81.8%) reported that students were required to produce a reflection, and 87.9% reported that students completed a post-rotation survey. Considering the benefits of CBDE for students' education and for improving access to oral health care, it is encouraging that over 45% of the responding schools required their students to spend four weeks or longer on external rotations. PMID- 27694291 TI - Predicting Rural Practice and Service to Indigent Patients: Survey of Dental Students Before and After Rural Community Rotations. AB - Community-based clinical rotations in rural areas expose dental students to diverse patient populations, practice models, and career opportunities as well as rural culture. The aims of this study at West Virginia University were to determine the best predictors of rural practice, assess the predictive validity of students' intention to practice in a rural area before and after their rural rotations, and evaluate the relationship between students' intention to practice in a rural area and intention to provide care for indigent patients. Online survey data were submitted pre- and post-rural clinical rotation by 432 of 489 dental students over the study period 2001-12, yielding an 88% response rate. In 2013, practice addresses from the West Virginia Board of Dentistry were added to the student database. The results showed that significant predictors of rural practice site were intended rural practice choice, rural hometown, and projected greater practice accessibility for indigent patients. The likelihood of students' predicting they would choose a rural practice increased after completion of their rural rotations. After the rotations, students predicted providing greater accessibility to indigent patients; these changes occurred for those who changed their predictions to rural practice choice after the rotations and those who subsequently entered rural practice. The dental students with a rural background or a greater service orientation were also more likely to expect to enter a rural practice and actually to do so after graduation. These findings suggest that dental school curricula that include rural rotations may increase students' sensitivity to issues of indigent patients and increase students' likelihood of rural practice choice. PMID- 27694293 TI - U.S. Dental Specialty Residents' Expectations and Anticipated Benefits of Academic Employment. AB - The aims of this study were to assess features of an academic career that dental specialty residents, as a group and by gender, find most attractive and to identify what determines their expectations for responsibilities and professional growth in academic employment. In November 2013, an invitation to participate in the study along with a link to an online survey was sent to the 407 U.S. program directors of six of the dental specialties (endodontics, oral and maxillofacial surgery, pediatric dentistry, periodontics, prosthodontics, and orthodontics), asking them to forward the survey to their residents. A total of 287 residents responded (112 [41.3%] female and 159 [58.7%] male) out of 4,400 enrolled in these specialty training programs (6.5% response rate). The female respondents were significantly more interested in joining academia than were the male respondents (female 48%; male 31.5%; p<0.005). Respondents of both genders were attracted to academic dentistry by opportunities for intellectual and professional stimulation, but the lifestyle of academicians was significantly more important for the female respondents. The most important feature of a successful academic career for the female respondents was the ability to have a good balance between career and personal life. While opportunity to conduct research was a positive feature for all residents interested in academia and both male and female respondents agreed strongly on the need for collaboration between faculty members for productive research, male respondents agreed significantly more than female respondents that faculty members should conduct independent research. Faculty members' feedback about academic employment were a significantly positive influence on those planning an academic career compared to those planning to enter private practice. This study found that the female and male residents differed in their expectations of responsibilities and professional growth in academic employment. These results may be useful for academic dental institutions and organizations when developing faculty recruitment and retention programs. PMID- 27694295 TI - Facilitating Dental Student Reflections: Using Mentor Groups to Discuss Clinical Experiences and Personal Development. AB - Despite the consensus on the importance of reflection for dental professionals, a lack of understanding remains about how students and clinicians should develop their ability to reflect. The aim of this study was to investigate dental students' and mentors' perceptions of mentor groups as an instructional method to facilitate students' reflection in terms of the strategy's learning potential, role of the mentor, group dynamics, and feasibility. At Ghent University in Belgium, third- and fourth-year dental students were encouraged to reflect on their clinical experiences and personal development in three reflective mentor sessions. No preparation or reports afterwards were required; students needed only to participate in the sessions. Sessions were guided by trained mentors to establish a safe environment, frame clinical discussions, and stimulate reflection. Students' and mentors' perceptions of the experience were assessed with a 17-statement questionnaire with response options on a five-point Likert scale (1=totally disagree to 5=totally agree). A total of 50 students and eight mentors completed the questionnaire (response rates 81% and 89%, respectively). Both students and mentors had neutral to positive perceptions concerning the learning potential, role of the mentor, group dynamics, and feasibility. The mean ideal total time for sessions in a year was 99 minutes (third-year students), 111 minutes (fourth-year students), and 147 minutes (mentors). Reported reflective topics related to patient management, frustrations, and practice of dentistry. Overall mean appreciation for the experience ranged from 14.50 to 15.14 on the 20 point scale. These findings about students' and mentors' positive perceptions of the experience suggest that mentor groups may be a potentially valuable strategy to promote dental students' reflection. PMID- 27694294 TI - Survey of Advanced Education in Prosthodontics Directors and Residents on Practices in Esthetic Dentistry. AB - The aim of this study was to determine the difference between the intended education by advanced education in prosthodontics (AEP) program directors and the perceived education received by AEP residents with respect to concepts of esthetic dentistry. Residents' confidence levels and current practices were also determined based on program level, with first- and second-year residents combined into "junior residents" and third- and fourth-year residents combined into "senior residents." Surveys were distributed to all U.S. and Canadian AEP program directors (N=52) in 2014 and residents (N=393) in 2015. The seven questions asked of directors and 20 asked of residents assessed resident training. The response rate for directors was 59.6% and for residents was 27.3%. Statistically significant results were found between the responding program directors' perceived education on esthetic principles and the responding residents' perceived education. The senior-level residents were more confident in each of the categories than residents at the junior level, although the difference was only significant for selecting porcelain systems to match inherent translucency, transfer of information to the laboratory, and surface staining or characterization. There was a difference between the program directors' intended teaching and the residents' perceptions with regards to bleaching, shade matching, selection of porcelain systems, transfer of information to the laboratory, and surface staining or characterization. The residents' confidence levels were higher at the senior level than those at the junior level in selecting porcelain systems, transfer of information to the laboratory, and staining/characterization. Faculty members in advanced prosthodontics programs may be able to use these findings to improve their residents' education in these areas. PMID- 27694296 TI - Quantifying Appointments, Treatment Time, Impressions, and Diagnostic Data of Cases Staffed by General Dentists and Prosthodontists in a Dental School Clinic. AB - The aim of this retrospective study was to quantify differences between general dentists and prosthodontists regarding appointments, treatment time, impressions, and preoperative diagnostic data in teaching predoctoral clinical fixed prosthodontics. Electronic dental records (n=356) of patients treated at one dental school in academic year 2012 were randomly selected for review to obtain the following data: faculty and student demographics, number of appointments and treatment time from preparation to cementation, number of impressions made, completion of oral disease control treatment (ODCT), and presence of preoperative periapical radiographs and diagnostic casts. The results showed that ODCT was completed in 78%, preoperative radiographs were present in 76%, and diagnostic casts made in 53% of the cases reviewed. There was no statistically significant difference in number of appointments, treatment time, or number of final impressions when students were staffed by general dentists or prosthodontists. When students were supervised by multiple faculty members, there was generally an increase in treatment time and number of appointments and final impressions. Although this study found no statistically significant differences between general dentists and prosthodontists regarding the criteria evaluated, the results suggest that faculty development and calibration are needed to ensure ODCT is completed and preoperative radiographs are present prior to initiating fixed prosthodontic procedures. PMID- 27694297 TI - Quality of Impressions and Work Authorizations Submitted by Dental Students Supervised by Prosthodontists and General Dentists. AB - Preclinical fixed prosthodontics is taught by Department of Prosthodontics faculty members at Virginia Commonwealth University School of Dentistry; however, 86% of all clinical cases in academic year 2012 were staffed by faculty members from the Department of General Practice. The aims of this retrospective study were to quantify the quality of impressions, accuracy of laboratory work authorizations, and most common errors and to determine if there were differences between the rate of errors in cases supervised by the prosthodontists and the general dentists. A total of 346 Fixed Prosthodontic Laboratory Tracking Sheets for the 2012 academic year were reviewed. The results showed that, overall, 73% of submitted impressions were acceptable at initial evaluation, 16% had to be poured first and re-evaluated for quality prior to pindexing, 7% had multiple impressions submitted for transfer dies, and 4% were rejected for poor quality. There were higher acceptance rates for impressions and work authorizations for cases staffed by prosthodontists than by general dentists, but the differences were not statistically significant (p=0.0584 and p=0.0666, respectively). Regarding the work authorizations, 43% overall did not provide sufficient information or had technical errors that delayed prosthesis fabrication. The most common errors were incorrect mountings, absence of solid casts, inadequate description of margins for porcelain fused to metal crowns, inaccurate die trimming, and margin marking. The percentages of errors in cases supervised by general dentists and prosthodontists were similar for 17 of the 18 types of errors identified; only for margin description was the percentage of errors statistically significantly higher for general dentist-supervised than prosthodontist-supervised cases. These results highlighted the ongoing need for faculty development and calibration to ensure students receive the highest quality education from all faculty members teaching fixed prosthodontics. PMID- 27694298 TI - Psychometric Evaluation of a 13-Point Measure of Students' Overall Competence in Community-Based Dental Education Programs. AB - Since 2006, the University of Michigan School of Dentistry has used a 13-point measure of overall competence instrument to assess fourth-year dental students' end-rotation performance at community clinics. The aim of this study was to assess the reliability and validity of this instrument used by preceptors to rate students' overall competence during community-based dental education experiences. The measure was analyzed using performance ratings for all fourth-year DDS students in the graduating classes of 2012 and 2013 (combined n=201). The results were that interrater agreement was satisfactory and the measure scored high for internal consistency; also, the measure loaded highly on a single overall competence factor. Ratings on this measure did not correlate with students' final cumulative dental school GPA, but showed a significant positive correlation with their fourth-year fall patient management grades (which signify students' conscientiousness in managing patients and their families in a professional and ethical manner). There were differences in grading systems between the 2012 cohort (which used a pass/fail system) and the 2013 cohort (which used a letter grade system) and the mean ratings they received (higher for the 2013 cohort). Overall, the study found that the 13-point measure demonstrated excellent reliability and validity, suggesting it is useful in determining a student's clinical competence in these settings. PMID- 27694299 TI - Developing and Testing the Short-Form Knowledge, Efficacy, and Practices Instrument for Assessing Cultural Competence. AB - The importance of educating dental students in cultural competence has been widely emphasized, but there is a need to assess cultural competence in a consistent and reliable way. The aims of this study were to determine latent constructs for the initial measure of cultural competence for oral health providers, the Knowledge, Efficacy, and Practices Instrument (KEPI), and to determine how well these factors related to previously identified latent constructs. Data were collected in surveys of dental students and from dental hygiene, dental assisting, and dental faculty members in 44 academic dental institutions from 2012 to 2015. There were a total of 1,786 respondents to the surveys; response rates to individual surveys ranged from 35% to 100%. There were 982 (55%) female and 804 (45%) male respondents, 286 (16%) underrepresented minority (URM) and 1,500 (84%) non-URM respondents, and 339 (19%) faculty and 1,447 (81%) student respondents. Three latent constructs were identified. Female respondents scored significantly higher on the culture-centered practice and efficacy of assessment factors, while URM respondents had significantly higher scores on all three of the KEPI factors. Measurements indicated that the long form KEPI could be shortened by ten questions and still have three meaningful measurements. Continued research in assessing other health care providers' cultural competence is needed to expand the KEPI to measure providers' cultural competence with patients with minority sexual orientation and gender identity issues and those with physical disabilities, mental illness, and autism to advance patient-centric communication. PMID- 27694301 TI - Peer Education: Reviews of the Literature (PERLs). PMID- 27694300 TI - Evaluating the Impact of Releasing an Item Pool on a Test's Empirical Characteristics. AB - Protecting the security of examination questions is an important task for high stakes examining boards/agencies and university programs. To maintain the security of questions, examining boards and university programs use a combination of prevention, detection, and enforcement strategies. A common prevention strategy is to establish a number of controls on access to questions; however, restricting access can motivate examinees to try harder to reconstruct questions that may appear on future versions of the test. Moreover, access to study materials by some groups and not others can present a challenge to the fairness of examinations. The aim of this study was to evaluate the empirical stability of test characteristics. Specifically, the primary research objective was to investigate the empirical stability of the items and test forms of a written examination before and after a specific policy decision was implemented. As a response to both of these concerns, this article describes a study that evaluated how psychometric (i.e., statistical) properties of test forms and individual questions might be affected by publicly releasing a larger number of questions from an item question pool. A series of analyses were conducted, including item drift to evaluate stability of the characteristics. The results suggest that empirical characteristics of the test forms and individual questions have remained relatively stable since the release policy was implemented. Specifically, statistical properties of the test forms have continued to perform similarly to test forms that were constructed prior to the release. Although the results of this study were promising, the context of this specific testing program may have offered additional protections such as a limited number of administrations that others may not. Therefore, testing/examining agencies and university programs may want to consider this strategy with appropriate caution. PMID- 27694302 TI - Combination of Open Subtotal Calcanectomy and Stabilization With External Fixation as Limb Salvage Procedure in Hindfoot-Infected Diabetic Foot Ulcers. AB - Diabetic hindfoot ulcers, complicated by osteomyelitis, are associated with a high risk of major amputation. Partial calcanectomy, preceded by an effective management of the infection and of the eventual peripheral artery disease, can be considered as valid therapeutic option. We have evaluated a therapeutic protocol for diabetic hindfoot ulcers complicated by osteomyelitis, which, besides an adequate surgical debridement, considers a reconstructive pathway assisted by the positioning of a circular external fixator. We made a prospective study of a cohort of diabetic patients affected by heel ulcer complicated by osteomyelitis. All patients underwent open partial calcanectomy associated with the positioning of a circular external frame specifically designed for hindfoot stabilization and offloading. A reconstructive procedure was implemented starting with the application of negative pressure wound therapy and coverage with dermal substitute and split thickness skin grafting. From November 2014 to November 2015, 18 consecutive patients were enrolled. Mean follow-up period was 212.3 +/- 64.0 days. Healing was achieved in 18 (100%) patients. The mean healing time was 69.0 +/- 64.0 days. No major amputation had to be performed during the follow-up. Open partial calcanectomy associated with external fixation and skin reconstruction was as efficient as limb salvage in patients with infected lesions of the hindfoot complicated by calcaneal osteomyelitis.

AB - The use of a validated screening questionnaire to identify individuals with chronic leg ulcers allows large-scale population-based studies to be conducted that measure and monitor the prevalence of the disease. The aim of this study was to design and validate such a screening questionnaire to identify patients with chronic leg ulcers. A simple 3-item questionnaire was developed at the Department of Dermatology, University Hospital of Zealand, Denmark. In total, 90 patients attending the department's outpatient clinic for dermatological diseases and chronic wounds were included in this study. All included participants completed the questionnaire and were subsequently examined by dermatologists. We found that the constructed 3-item questionnaire in this study had a sensitivity and specificity of 95% and 93% and a positive predictive value and negative predictive value of 78% and 95%, respectively. Moreover, we found that the use of the 3-item questionnaire, as compared with a single question, in which the participants were asked whether they currently have a leg ulcer, resulted in significantly higher positive predictive value (+11.6%, P = .035) and specificity (+5.6%, P = .046) of the diagnostic test. Future studies are merited to investigate the diagnostic accuracy of the questionnaire in other populations and settings. PMID- 27694304 TI - Preoperative Angiographic Criteria for Predicting Free-Flap Transfer Outcomes in Patients With Lower-Extremity Peripheral Arterial Disease. AB - Patients scheduled for microsurgical reconstruction of the lower leg often receive preoperative assessment of recipient vessels using angiography. However, no clear standard is available for evaluating angiographic results to predict free-flap survival outcomes. We developed angiographic criteria for predicting surgical outcome in patients with lower-extremity peripheral arterial disease based on abnormality of the anterior tibial and posterior tibial arteries. We applied the criteria to a small number of patients scheduled for microsurgical reconstruction of the lower leg. Angiographies with arterial abnormalities were classified into 3 groups: favorable free-flap survival, compromised free-flap survival, and postsurgical pedal ischemia. The study enrolled 50 patients between 2005 and 2013. In 42% of patients, arterial abnormalities were observed by angiography. Age >65 years was the strongest risk factor for development of lower leg arterial abnormality ( P < .001). The anterior tibial and peroneal arteries were significantly more stenotic than other vessels. In the favorable free-flap survival and compromised free-flap survival groups, free-flap transfers were attempted in 7 patients but intraoperatively abandoned in 2 patients, with postoperative failure in 1 patient. In the postsurgical pedal ischemia group, free-flap transfers were attempted in 10 patients but intraoperatively abandoned in 6 patients, with postoperative failure in 3. PMID- 27694305 TI - In vitro germ cell differentiation from embryonic stem cells of mice: induction control by BMP4 signalling. AB - The present study aims to confirm and analyse germ cell-related patterns and specific gene expressions at a very early stage of cell commitment. Following the XY cytogenetic confirmation of the CCE mouse embryonic stem cells (mESCs) line, cells were cultured to form embryoid bodies (EBs). Expression pattern assessment of the mouse vasa homologue (Mvh), Stra8, alpha6 and beta1 integrin genes in ESC and 1-3-day-old EB showed that all genes except alpha6 integrin were expressed in the ESC. The mean calibration of Mvh, Stra8 and alpha6 integrin expression significantly increased upon EB formation compared with the ESCs. During mouse embryogenesis, the signalling of bone morphogenetic protein (BMP) is essential for germ-line formation. To investigate its role in germ-line induction in vitro, mESCs were cultured as 1-day-old EB aggregates with BMP4 for 4 days in STO co culture systems, in the presence and absence of 5 ng/ml BMP4. At the end of the culture period, colony assay (number and diameter) was performed and the viability percentage and proliferation rate was determined. There were no significant statistical differences in the abovementioned criteria between these two groups. Moreover, the expression of Mvh, alpha6 and beta1 integrins, Stra8 and Piwil2 genes was evaluated in co-culture groups. The molecular results of co culture groups showed higher-but insignificant-Piwil2 and significant alpha6 integrin expressions in BMP4 treated co-culture systems. These results confirmed that the EB system and the presence of BMP4 in a STO co-culture system improve the differentiation of ESCs to germ cell. PMID- 27694306 TI - Mycophenolic Acid-Induced Developmental Defects in Zebrafish Embryos. AB - With the increasing use of mycophenolic acid (MPA) in solid organ transplantation, some clinical studies indicate that it is also a human teratogen. However, it is unknown by which mechanism MPA acts as a teratogen. Mycophenolic acid was a selective blocker of de novo purine synthesis, and its immunosuppressive effect is mediated by the inhibition of inosine monophosphate dehydrogenase, which could be a target for MPA-induced toxicity as well. The aim of our study was to examine the direct influence of MPA exposure on zebrafish (Danio rerio) embryos. Morphological defects including tail curvature and severe pericardial edema in zebrafish embryos caused by MPA (3.7-11.1 umol/L) were found in a dose-dependent manner. The teratogenic index (25% lethal concentration value (LC25)/no observed adverse effect level ratio) was 16, which indicated MPA as a teratogen. Quantitative polymerase chain reaction analysis revealed that the expression level of impdh1b and impdh2 was significantly reduced by MPA treatment at 8 umol/L (equals to LC25 level). All the toxic effects could be partially reversed by the addition of 33.3 umol/L guanosine. Our results indicated that MPA impairs the development of zebrafish embryos via inhibition of impdh activity, which subsequently caused a guanosine nucleotide depletion in vivo. PMID- 27694308 TI - Analyzing structure-function relationships of artificial and cancer-associated PARP1 variants by reconstituting TALEN-generated HeLa PARP1 knock-out cells. AB - Genotoxic stress activates PARP1, resulting in the post-translational modification of proteins with poly(ADP-ribose) (PAR). We genetically deleted PARP1 in one of the most widely used human cell systems, i.e. HeLa cells, via TALEN-mediated gene targeting. After comprehensive characterization of these cells during genotoxic stress, we analyzed structure-function relationships of PARP1 by reconstituting PARP1 KO cells with a series of PARP1 variants. Firstly, we verified that the PARP1?E988K mutant exhibits mono-ADP-ribosylation activity and we demonstrate that the PARP1?L713F mutant is constitutively active in cells. Secondly, both mutants exhibit distinct recruitment kinetics to sites of laser induced DNA damage, which can potentially be attributed to non-covalent PARP1-PAR interaction via several PAR binding motifs. Thirdly, both mutants had distinct functional consequences in cellular patho-physiology, i.e. PARP1?L713F expression triggered apoptosis, whereas PARP1?E988K reconstitution caused a DNA-damage induced G2 arrest. Importantly, both effects could be rescued by PARP inhibitor treatment, indicating distinct cellular consequences of constitutive PARylation and mono(ADP-ribosyl)ation. Finally, we demonstrate that the cancer-associated PARP1 SNP variant (V762A) as well as a newly identified inherited PARP1 mutation (F304L?V762A) present in a patient with pediatric colorectal carcinoma exhibit altered biochemical and cellular properties, thereby potentially supporting human carcinogenesis. Together, we establish a novel cellular model for PARylation research, by revealing strong structure-function relationships of natural and artificial PARP1 variants. PMID- 27694307 TI - Distribution and effects of amino acid changes in drug-resistant alpha and beta herpesviruses DNA polymerase. AB - Emergence of drug-resistance to all FDA-approved antiherpesvirus agents is an increasing concern in immunocompromised patients. Herpesvirus DNA polymerase (DNApol) is currently the target of nucleos(t)ide analogue-based therapy. Mutations in DNApol that confer resistance arose in immunocompromised patients infected with herpes simplex virus 1 (HSV-1) and human cytomegalovirus (HCMV), and to lesser extent in herpes simplex virus 2 (HSV-2), varicella zoster virus (VZV) and human herpesvirus 6 (HHV-6). In this review, we present distinct drug resistant mutational profiles of herpesvirus DNApol. The impact of specific DNApol amino acid changes on drug-resistance is discussed. The pattern of genetic variability related to drug-resistance differs among the herpesviruses. Two mutational profiles appeared: one favoring amino acid changes in the Palm and Finger domains of DNApol (in alpha-herpesviruses HSV-1, HSV-2 and VZV), and another with mutations preferentially in the 3'-5' exonuclease domain (in beta herpesvirus HCMV and HHV-6). The mutational profile was also related to the class of compound to which drug-resistance emerged. PMID- 27694309 TI - Activation of cGAS-dependent antiviral responses by DNA intercalating agents. AB - Acridine dyes, including proflavine and acriflavine, were commonly used as antiseptics before the advent of penicillins in the mid-1940s. While their mode of action on pathogens was originally attributed to their DNA intercalating activity, work in the early 1970s suggested involvement of the host immune responses, characterized by induction of interferon (IFN)-like activities through an unknown mechanism. We demonstrate here that sub-toxic concentrations of a mixture of acriflavine and proflavine instigate a cyclic-GMP-AMP (cGAMP) synthase (cGAS)-dependent type-I IFN antiviral response. This pertains to the capacity of these compounds to induce low level DNA damage and cytoplasmic DNA leakage, resulting in cGAS-dependent cGAMP-like activity. Critically, acriflavine:proflavine pre-treatment of human primary bronchial epithelial cells significantly reduced rhinovirus infection. Collectively, our findings constitute the first evidence that non-toxic DNA binding agents have the capacity to act as indirect agonists of cGAS, to exert potent antiviral effects in mammalian cells. PMID- 27694311 TI - Infomap Bioregions: Interactive Mapping of Biogeographical Regions from Species Distributions. AB - Biogeographical regions (bioregions) reveal how different sets of species are spatially grouped and therefore are important units for conservation, historical biogeography, ecology, and evolution. Several methods have been developed to identify bioregions based on species distribution data rather than expert opinion. One approach successfully applies network theory to simplify and highlight the underlying structure in species distributions. However, this method lacks tools for simple and efficient analysis. Here, we present Infomap Bioregions, an interactive web application that inputs species distribution data and generates bioregion maps. Species distributions may be provided as georeferenced point occurrences or range maps, and can be of local, regional, or global scale. The application uses a novel adaptive resolution method to make best use of often incomplete species distribution data. The results can be downloaded as vector graphics, shapefiles, or in table format. We validate the tool by processing large data sets of publicly available species distribution data of the world's amphibians using species ranges, and mammals using point occurrences. We then calculate the fit between the inferred bioregions and WWF ecoregions. As examples of applications, researchers can reconstruct ancestral ranges in historical biogeography or identify indicator species for targeted conservation.

AB - Differential expression analysis of RNA sequencing (RNA-seq) data typically relies on reconstructing transcripts or counting reads that overlap known gene structures. We previously introduced an intermediate statistical approach called differentially expressed region (DER) finder that seeks to identify contiguous regions of the genome showing differential expression signal at single base resolution without relying on existing annotation or potentially inaccurate transcript assembly.We present the derfinder software that improves our annotation-agnostic approach to RNA-seq analysis by: (i) implementing a computationally efficient bump-hunting approach to identify DERs that permits genome-scale analyses in a large number of samples, (ii) introducing a flexible statistical modeling framework, including multi-group and time-course analyses and (iii) introducing a new set of data visualizations for expressed region analysis. We apply this approach to public RNA-seq data from the Genotype-Tissue Expression (GTEx) project and BrainSpan project to show that derfinder permits the analysis of hundreds of samples at base resolution in R, identifies expression outside of known gene boundaries and can be used to visualize expressed regions at base-resolution. In simulations, our base resolution approaches enable discovery in the presence of incomplete annotation and is nearly as powerful as feature-level methods when the annotation is complete.derfinder analysis using expressed region-level and single base-level approaches provides a compromise between full transcript reconstruction and feature-level analysis. The package is available from Bioconductor at www.bioconductor.org/packages/derfinder. PMID- 27694312 TI - Performance of short ECG recordings twice daily to detect paroxysmal atrial fibrillation in stroke and transient ischemic attack patients. AB - Aims Prolonged cardiac monitoring after stroke is recommended though there is no consensus on optimal methods. Short-term ECG recordings with a "thumb-ECG" device have shown promising preliminary results regarding effectiveness and cost benefit. We aimed to examine the performance of thumb-ECG and five days' Holter monitoring in a prospective trial. A secondary endpoint was the inter-observer agreement of the thumb-ECG. Methods Patients older than 65 years with no history of atrial fibrillation who suffered an acute stroke or transient ischemic attack of unknown origin were prospectively included. Patients were monitored for atrial fibrillation with five days' Holter and concurrent 30 s thumb-ECG twice daily, the latter continuing for 30 days. Inter-observer agreement for the thumb-ECG was determined. Results One hundred patients were included and 95 patients were analyzed. Paroxysmal atrial fibrillation was diagnosed in 20 patients with the thumb-ECG recordings and 17 patients on the Holter monitoring. Only 10 were diagnosed with both methods. The difference between the detection rates of the two devices was not significant ( p = 0.63). The inter-observer agreement of the thumb-ECG had a kappa value of 0.65. Conclusion Thirty days' thumb-ECG recordings twice daily for 30 s detect a high proportion of paroxysmal atrial fibrillation in a stroke or transient ischemic attack cohort. The proportion was comparable to five days' Holter monitoring but the agreement between the two methods was poor and the trial was not powered to detect a minor difference between the devices. The inter-observer agreement for the thumb-ECG was substantial. www.clinicalTrials.gov UI: NCT02261766. PMID- 27694314 TI - Changes in stroke incidence, outcome, and associated factors in Porto between 1998 and 2011. AB - Objective Year 2000 marked a turning point in stroke prevention and treatment in Portugal. In face of high incidence rates stroke awareness campaigns, close surveillance of vascular risk factors and implementation of hospital stroke units were advanced by the National Health Authorities. To understand the effect of such measures, we assessed changes in stroke incidence and short-term outcome using data from two community-based registers undertaken in Porto in 1998-2000 and 2009-2011. Methods We used standard diagnostic criteria and multiple overlapping sources of case-ascertainment for first-ever strokes. Short-term outcome was measured by the modified Rankin Scale; disabling stroke was defined whenever post-stroke mRS score>pre-stroke mRS and >1. Results Globally, 462 and 405 first-ever stroke cases were registered in 1998-2000 and 2009-2011, respectively. Stroke incidence decreased by 23%, from 261 to 203/100,000 after adjustment for the Portuguese population. Significant reduction was found in those aged <75 years (31%) and in women (32%). Incidence of disabling strokes was reduced by 29%. Fatal strokes decreased by 46%, while intracerebral hemorrhage decreased by 51%. Risk of disability from stroke decreased by 11% (RR = 0.89; 95%CI, 0.81-0.98) in 2009-2011, as found after adjusting for patient/stroke characteristics in a Poisson model. Moreover, when patients arrived hospital within 3 h from stroke onset, the risk of disabling stroke was 0.76 (95%CI, 0.67 0.87) in 2009-2011 vs. 1998-2000, compared to 1.03 (95%CI, 0.89-1.12) for late arrival. Conclusion Risk of stroke, mainly of hemorrhagic stroke, was substantially reduced over time. Timely action in acute phase was responsible for the decline in disability across periods. PMID- 27694313 TI - Stroke Epidemiology in an Australian Rural Cohort (SEARCH). AB - Background Stroke rates in Australia and New Zealand have been declining since 1990 but all studies have been completed in large urban centers. Aim We report the first Australasian stroke incidence study in a rural population. Methods The authors applied the principle of complete ascertainment, used the WHO standard definition of stroke and classified ischemic stroke by the TOAST criteria. Data were collected from five rural centers defined by postcode of residence, over a 2 year period with 12 months of follow up of all cases. Results There were 217 strokes in 215 individuals in a population of 96,036 people, over 2 years, giving a crude attack rate of 113 per 100,000 per year. The 181 first-ever strokes (83% of total), standardized to the WHO world population, occurred at a rate of 50/100,000 (95% CI: 43-58). The 28-day fatality for first-ever strokes was 24% (95% CI: 18-31) and 77% (95% CI: 71-83) were classified as ischemic (140/181), 15% (95% CI: 10-21) intracerebral hemorrhage, 3% (95% CI: 1-6) due to subarachnoid hemorrhage and 5% (95% CI: 2-9) were unknown. A high proportion of first-ever ischemic strokes (44%) were cardioembolic, mostly (77%) due to atrial arrhythmias. Of the 38 with known atrial arrhythmias prior to stroke, only six (16%) were therapeutically anticoagulated. Conclusions This rural companion study of a recent Australian urban stroke incidence study confirms the downward trend of stroke incidence in Australia, and reiterates that inadequate anticoagulation of atrial arrhythmia remains a preventable cause of ischemic stroke.

AB - Rheumatic manifestations may be prevalent in more than 30% of patients with infective endocarditis (IE), often predating this diagnosis by several months. A case series of five patients recorded at a tertiary care Rheumatology and Clinical Immunology unit over a period of 1 year emphasises that varied presentations of endocarditis may mimic uncommon rheumatic diseases. PMID- 27694315 TI - Thrombolysis and thrombectomy in patients treated with dabigatran with acute ischemic stroke: Expert opinion. AB - Systemic thrombolysis with rt-PA is contraindicated in patients with acute ischemic stroke anticoagulated with dabigatran. This expert opinion provides guidance on the use of the specific reversal agent idarucizumab followed by rt-PA and/or thrombectomy in patients with ischemic stroke pre-treated with dabigatran. The use of idarucizumab followed by rt-PA is covered by the label of both drugs. PMID- 27694319 TI - Metamizole (dipyrone) effects on sevoflurane requirements and postoperative hyperalgesia in rats. AB - Unlike non-steroidal anti-inflammatory drugs (NSAIDs), metamizole has poor anti inflammatory effects; and is suitable for models where analgesia, but not anti inflammatory effects, is desirable. Like opioids, these drugs produce perioperative analgesia while reducing anaesthetic requirements, but it remains unclear whether they may develop tolerance or hyperalgesia, and thus decrease in analgesic efficacy. The aim was to determine whether tolerance or hyperalgesia to metamizole occurred in rats, and whether the sevoflurane minimum alveolar concentration (MAC) was affected. In a randomized, prospective, controlled study, male Wistar rats ( n = 8 per group) were administered metamizole (300 mg/kg, day 4). Previously, the following treatments were provided: daily metamizole for four days (0-3), morphine (10 mg/kg; positive control, day 0 only) or saline (negative control). The main outcome measures were mechanical (MNT) and warm thermal (WNT) nociceptive quantitative sensory thresholds. The baseline sevoflurane MAC and the reduction produced by the treatments were also determined. The mean (SD) baseline MAC [2.4(0.2)%vol] was decreased by morphine and metamizole by 45(11)% and 33(7)% ( P = 0.000, both), respectively. Baseline MNT [35.4(4.5) g] and WNT [13.2(2.4) s] were decreased by morphine and metamizole: MNT reduction of 22(6)% ( P = 0.000) and 22(7)% ( P = 0.001), respectively and WNT reduction of 34(14)% ( P = 0.000) and 24(13)% ( P = 0.001). The baseline MAC on day 4 was neither modified by treatments nor the MAC reduction produced by metamizole (days 0 and 4; P > 0.05). In conclusion, repeated metamizole administration may produce hyperalgesia, although it may not modify its anaesthetic sparing effect. The clinical relevance of this effect in painful research models requiring prolonged analgesic therapy warrants further investigation. PMID- 27694318 TI - Ventral striatum and amygdala activity as convergence sites for early adversity and conduct disorder. AB - Childhood family adversity (CFA) increases the risk for conduct disorder (CD) and has been associated with alterations in regions of affective processing like ventral striatum (VS) and amygdala. However, no study so far has demonstrated neural converging effects of CFA and CD in the same sample. At age 25 years, functional MRI data during two affective tasks, i.e. a reward (N = 171) and a face-matching paradigm (N = 181) and anatomical scans (N = 181) were acquired in right-handed currently healthy participants of an epidemiological study followed since birth. CFA during childhood was determined using a standardized parent interview. Disruptive behaviors and CD diagnoses during childhood and adolescence were obtained by diagnostic interview (2-19 years), temperamental reward dependence was assessed by questionnaire (15 and 19 years).CFA predicted increased CD and amygdala volume. Both exposure to CFA and CD were associated with a decreased VS response during reward anticipation and blunted amygdala activity during face-matching. CD mediated the effect of CFA on brain activity. Temperamental reward dependence was negatively correlated with CFA and CD and positively with VS activity. These findings underline the detrimental effects of CFA on the offspring's affective processing and support the importance of early postnatal intervention programs aiming to reduce childhood adversity factors. PMID- 27694320 TI - Polyphosphate colocalizes with factor XII on platelet-bound fibrin and augments its plasminogen activator activity. AB - Activated factor XII (FXIIa) has plasminogen activator capacity but its relative contribution to fibrinolysis is considered marginal compared with urokinase and tissue plasminogen activator. Polyphosphate (polyP) is released from activated platelets and mediates FXII activation. Here, we investigate the contribution of polyP to the plasminogen activator function of alphaFXIIa. We show that both polyP70, of the chain length found in platelets (60-100 mer), and platelet derived polyP significantly augment the plasminogen activation capacity of alphaFXIIa. PolyP70 stimulated the autoactivation of FXII and subsequent plasminogen activation, indicating that once activated, alphaFXIIa remains bound to polyP70 Indeed, complex formation between polyP70 and alphaFXIIa provides protection against autodegradation. Plasminogen activation by betaFXIIa was minimal and not enhanced by polyP70, highlighting the importance of the anion binding site. PolyP70 did not modulate plasmin activity but stimulated activation of Glu and Lys forms of plasminogen by alphaFXIIa. Accordingly, polyP70 was found to bind to FXII, alphaFXIIa, and plasminogen, but not betaFXIIa. Fibrin and polyP70 acted synergistically to enhance alphaFXIIa-mediated plasminogen activation. The plasminogen activator activity of the alphaFXIIa-polyP70 complex was modulated by C1 inhibitor and histidine-rich glycoprotein, but not plasminogen activator inhibitors 1 and 2. Platelet polyP and FXII were found to colocalize on the activated platelet membrane in a fibrin-dependent manner and decorated fibrin strands extending from platelet aggregates. We show that in the presence of platelet polyP and the downstream substrate fibrin, alphaFXIIa is a highly efficient and favorable plasminogen activator. Our data are the first to document a profibrinolytic function of platelet polyP. PMID- 27694322 TI - Hedgehog pathway activation in T-cell acute lymphoblastic leukemia predicts response to SMO and GLI1 inhibitors. AB - T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive childhood leukemia that is caused by the accumulation of multiple genomic lesions resulting in transcriptional deregulation and increased cell proliferation and survival. Through analysis of gene expression data, we provide evidence that the hedgehog pathway is activated in 20% of T-ALL samples. Hedgehog pathway activation is associated with ectopic expression of the hedgehog ligands Sonic hedgehog (SHH) or Indian hedgehog (IHH), and with upregulation of the transcription factor GLI1 Ectopic expression of SHH or IHH in mouse T cells in vivo caused hedgehog pathway activation in both lymphoid and epithelial cells in the thymus and resulted in increased expression of important T-cell stimulatory ligands (Dll4, Il7, and Vegf) by thymic epithelial cells. In T-ALL cell lines, pharmacological inhibition or short interfering RNA-mediated knockdown of SMO or GLI1 led to decreased cell proliferation. Moreover, primary T-ALL cases with high GLI1 messenger RNA levels, but not those with low or undetectable GLI1 expression, were sensitive to hedgehog pathway inhibition by GANT61 or GDC-0449 (vismodegib) using ex vivo cultures and in vivo xenograft models. We identify the hedgehog pathway as a novel therapeutic target in T-ALL and demonstrate that hedgehog inhibitors approved by the US Food and Drug Administration could be used for the treatment of this rare leukemia. PMID- 27694321 TI - Inverse agonism at the P2Y12 receptor and ENT1 transporter blockade contribute to platelet inhibition by ticagrelor. AB - Ticagrelor is a potent antagonist of the P2Y12 receptor (P2Y12R) and consequently an inhibitor of platelet activity effective in the treatment of atherothrombosis. Here, we sought to further characterize its molecular mechanism of action. Initial studies showed that ticagrelor promoted a greater inhibition of adenosine 5'-diphosphate (ADP)-induced Ca2+ release in washed platelets vs other P2Y12R antagonists. This additional effect of ticagrelor beyond P2Y12R antagonism was in part as a consequence of ticagrelor inhibiting the equilibrative nucleoside transporter 1 (ENT1) on platelets, leading to accumulation of extracellular adenosine and activation of Gs-coupled adenosine A2A receptors. This contributed to an increase in basal cyclic adenosine monophosphate (cAMP) and vasodilator stimulated phosphoprotein phosphorylation (VASP-P). In addition, ticagrelor increased platelet cAMP and VASP-P in the absence of ADP in an adenosine receptor independent manner. We hypothesized that this increase originated from a direct effect on basal agonist-independent P2Y12R signaling, and this was validated in 1321N1 cells stably transfected with human P2Y12R. In these cells, ticagrelor blocked the constitutive agonist-independent activity of the P2Y12R, limiting basal Gi-coupled signaling and thereby increasing cAMP levels. These data suggest that ticagrelor has the pharmacological profile of an inverse agonist. Based on our results showing insurmountable inhibition of ADP-induced Ca2+ release and forskolin-induced cAMP, the mode of antagonism of ticagrelor also appears noncompetitive, at least functionally. In summary, our studies describe 2 novel modes of action of ticagrelor, inhibition of platelet ENT1 and inverse agonism at the P2Y12R that contribute to its effective inhibition of platelet activation.

AB - INTRODUCTION: Most studies on nematode-malaria interactions were conducted outside of the Americas. The objective of the present study was thus to study the relation between malaria and nematodes in a cohort of children in an Amazonian village. METHODS: Odds ratios for intestinal nematode infections as an explanatory variable to malaria resistant vs. malaria sensitive were computed. RESULTS: Ascaris lumbricoides was significantly more frequent in the 'resistant' malaria group than in the 'sensitive' one. CONCLUSIONS: Despite its low statistical power, the present results find that Ascaris was associated with less malaria, as observed by a number of studies.

AB - BACKGROUND: There are poorer outcomes following ST elevation myocardial infarction in blacks compared to white patients despite comparable door-to reperfusion time. We hypothesized that delays to hospital presentation may be contributory. METHODS AND RESULTS: We conducted a retrospective analysis of the 1144 patients admitted for STEMI in our institution from 2008 to 2013. The door to-balloon time (D2BT) and symptom-onset-to-door time (SODT) were compared by race. Bivariate analysis was done comparing the median D2BT and SODT. Stratified analyses were done to evaluate the effect of race on D2BT and SODT, accounting for insurance status, age, sex and comorbidities. The mean age was 59+/-13 years; 56% of this population was black and 41% was white. Males accounted for 66% of this population. The median D2BT was 60 minutes (interquartile range [IQR] 42 82), and median SODT was 120 minutes (IQR 60-720). There was no significant difference in D2BT by race (P=0.86). Black patients presented to the emergency room (ER) later than whites (SODT=180 [IQR 60-1400] vs 120 [IQR 60-560] minutes, P<0.01) and were more likely to be uninsured (P<0.01). After controlling for comorbidities, insurance, and socioeconomic status, blacks were 60% more likely to present late after a STEMI (OR 1.6, P<0.01). A subset analysis excluding transferred patients showed similar results. CONCLUSIONS: Black patients present later to the ER after STEMI with no difference in D2BT compared to whites. This difference in time to presentation may be one of the factors accounting for poor outcomes in this population. PMID- 27694326 TI - Percutaneous Pulmonary Valve Implantation Alters Electrophysiologic Substrate. AB - BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is first-line therapy for some congenital heart disease patients with right ventricular outflow tract dysfunction. The hemodynamics improvements after PPVI are well documented, but little is known about its effects on the electrophysiologic substrate. The objective of this study is to assess the short- and medium-term electrophysiologic substrate changes and elucidate postprocedure arrhythmias. METHODS AND RESULTS: A retrospective chart review of patients undergoing PPVI from May 2010 to April 2015 was performed. A total of 106 patients underwent PPVI; most commonly these patients had tetralogy of Fallot (n=59, 55%) and pulmonary insufficiency (n=60, 57%). The median follow-up time was 28 months (7 63 months). Pre-PPVI, 25 patients (24%) had documented arrhythmias: nonsustained ventricular tachycardia (NSVT) (n=9, 8%), frequent premature ventricular contractions (PVCs) (n=6, 6%), and atrial fibrillation/flutter (AF/AFL) (n=10, 9%). Post-PPVI, arrhythmias resolved in 4 patients who had NSVT (44%) and 5 patients who had PVCs (83%). New arrhythmias were seen in 16 patients (15%): 7 NSVT, 8 PVCs, and 1 AF/AFL. There was resolution at medium-term follow-up in 6 (86%) patients with new-onset NSVT and 7 (88%) patients with new-onset PVCs. There was no difference in QRS duration pre-PPVI, post-PPVI, and at medium-term follow-up (P=0.6). The median corrected QT lengthened immediately post-PPVI but shortened significantly at midterm follow-up (P<0.01). CONCLUSIONS: PPVI reduced the prevalence of NSVT. The majority of postimplant arrhythmias resolve by 6 months of follow-up.

AB - BACKGROUND: Experimental uremic cardiomyopathy causes cardiac fibrosis and is causally related to the increased circulating levels of the cardiotonic steroid, marinobufagenin (MBG), which signals through Na/K-ATPase. Rapamycin is an inhibitor of the serine/threonine kinase mammalian target of rapamycin (mTOR) implicated in the progression of many different forms of renal disease. Given that Na/K-ATPase signaling is known to stimulate the mTOR system, we speculated that the ameliorative effects of rapamycin might influence this pathway. METHODS AND RESULTS: Biosynthesis of MBG by cultured human JEG-3 cells is initiated by CYP27A1, which is also a target for rapamycin. It was demonstrated that 1 MUmol/L of rapamycin inhibited production of MBG in human JEG-2 cells. Male Sprague Dawley rats were subjected to either partial nephrectomy (PNx), infusion of MBG, and/or infusion of rapamycin through osmotic minipumps. PNx animals showed marked increase in plasma MBG levels (1025+/-60 vs 377+/-53 pmol/L; P<0.01), systolic blood pressure (169+/-1 vs 111+/-1 mm Hg; P<0.01), and cardiac fibrosis compared to controls. Plasma MBG levels were significantly decreased in PNx-rapamycin animals compared to PNx (373+/-46 vs 1025+/-60 pmol/L; P<0.01), and cardiac fibrosis was substantially attenuated by rapamycin treatment. CONCLUSIONS: Rapamycin treatment in combination with MBG infusion significantly attenuated cardiac fibrosis. Our results suggest that rapamycin may have a dual effect on cardiac fibrosis through (1) mTOR inhibition and (2) inhibiting MBG-mediated profibrotic signaling and provide support for beneficial effect of a novel therapy for uremic cardiomyopathy.

PMID- 27694327 TI - Nonsustained Atrial Fibrillation in Ischemic Stroke Patients and Stroke-Free Controls From the Perspective of Stroke Pathophysiology. AB - BACKGROUND: Short-lasting (<30 s), nonsustained episodes of atrial fibrillation (NS-AF) are considered a risk factor for future development of paroxysmal or persistent AF. Nonetheless, their causal role in stroke pathogenesis is currently unknown. In this study we determined the frequency of NS-AF, together with the associated clinical and imaging features, in stroke-free controls and ischemic stroke patients. METHODS AND RESULTS: A total of 332 controls, >=50 years of age and no prior history of stroke or AF, were evaluated with 24-hour Holter monitoring for the presence of <30-s-long AF episodes. The demographic and cardiovascular features of this cohort, together with imaging finding on magnetic resonance imaging, were compared to a consecutive series of >=50-year-old ischemic stroke patients without AF (n=498). The prevalence of NS-AF was significantly higher among ischemic stroke patients in comparison to controls (37% versus 27%; P=0.002). In multivariable analyses, after adjustment for demographic and cardiovascular risk factors, patients with ischemic stroke were more likely to harbor NS-AF episodes (odds ratio 1.43; 95% CI 1.01-2.02; P=0.041). The association between ischemic stroke and NS-AF weakened when the analyses were restricted to cryptogenic stroke patients (odds ratio 1.31; 95% CI 0.82-2.08). No significant association was observed between the presence of chronic cortical infarcts and NS-AF. CONCLUSIONS: Our study shows a higher prevalence of NS-AF episodes in ischemic stroke patients in comparison to controls. Nonetheless, the lack of a stronger association with cryptogenic strokes and absence of a relationship with chronic cortical infarcts brings into question the causal influence of NS-AF in the ischemic stroke setting.

AB - BACKGROUND: The development of atherosclerosis is strongly linked to disorders of cholesterol metabolism. Matrix metalloproteinases (MMPs) are dysregulated in patients and animal models with atherosclerosis. Whether systemic MMP activity influences cholesterol metabolism is unknown. METHODS AND RESULTS: We examined MMP-9-deficient (Mmp9-/-) mice and found them to have abnormal lipid gene transcriptional responses to dietary cholesterol supplementation. As opposed to Mmp9+/+ (wild-type) mice, Mmp9-/- mice failed to decrease the hepatic expression of sterol regulatory element binding protein 2 pathway genes, which control hepatic cholesterol biosynthesis and uptake. Furthermore, Mmp9-/- mice failed to increase the expression of genes encoding the rate-limiting enzymes in biliary cholesterol excretion (eg, Cyp7a and Cyp27a). In contrast, MMP-9 deficiency did not impair intestinal cholesterol absorption, as shown by the 14C-cholesterol and 3H-sitostanol absorption assay. Similar to our earlier study on Mmp2-/- mice, we observed that Mmp9-/- mice had elevated plasma secreted phospholipase A2 activity. Pharmacological inhibition of systemic circulating secreted phospholipase A2 activity (with varespladib) partially normalized the hepatic transcriptional responses to dietary cholesterol in Mmp9-/- mice. Functional studies with mice deficient in other MMPs suggested an important role for the MMP system, as a whole, in modulation of cholesterol metabolism. CONCLUSIONS: Our results show that MMP-9 modulates cholesterol metabolism, at least in part, through a novel MMP-9-plasma secreted phospholipase A2 axis that affects the hepatic transcriptional responses to dietary cholesterol. Furthermore, the data suggest that dysregulation of the MMP system can result in metabolic disorder, which could lead to atherosclerosis and coronary heart disease. PMID- 27694331 TI - A Role for Human N-alpha Acetyltransferase 30 (Naa30) in Maintaining Mitochondrial Integrity. AB - N-terminal acetylation (Nt-acetylation) by N-terminal acetyltransferases (NATs) is one of the most common protein modifications in eukaryotes. The NatC complex represents one of three major NATs of which the substrate profile remains largely unexplored. Here, we defined the in vivo human NatC Nt-acetylome on a proteome wide scale by combining knockdown of its catalytic subunit Naa30 with positional proteomics. We identified 46 human NatC substrates, expanding our current knowledge on the substrate repertoire of NatC which now includes proteins harboring Met-Leu, Met-Ile, Met-Phe, Met-Trp, Met-Val, Met-Met, Met-His and Met Lys N termini. Upon Naa30 depletion the expression levels of several organellar proteins were found reduced, in particular mitochondrial proteins, some of which were found to be NatC substrates. Interestingly, knockdown of Naa30 induced the loss of mitochondrial membrane potential and fragmentation of mitochondria. In conclusion, NatC Nt-acetylates a large variety of proteins and is essential for mitochondrial integrity and function. PMID- 27694332 TI - Energetics of acclimation to NaCl by submerged, anoxic rice seedlings. AB - BACKGROUND AND AIMS: Our aim was to elucidate how plant tissues under a severe energy crisis cope with imposition of high NaCl, which greatly increases ion fluxes and hence energy demands. The energy requirements for ion regulation during combined salinity and anoxia were assessed to gain insights into ion transport processes in the anoxia-tolerant coleoptile of rice. METHODS: We studied the combined effects of anoxia plus 50 or 100 mm NaCl on tissue ions and growth of submerged rice (Oryza sativa) seedlings. Excised coleoptiles allowed measurements in aerated or anoxic conditions of ion net fluxes and O2 consumption or ethanol formation and by inference energy production. KEY RESULTS: Over 80 h of anoxia, coleoptiles of submerged intact seedlings grew at 100 mm NaCl, but excised coleoptiles, with 50 mm exogenous glucose, survived only at 50 mm NaCl, possibly due to lower energy production with glucose than for intact coleoptiles with sucrose as substrate. Rates of net uptake of Na+ and Cl- by coleoptiles in anoxia were about half those in aerated solution. Ethanol formation in anoxia and O2 uptake in aerobic solution were each increased by 13-15 % at 50 mm NaCl, i.e. ATP formation was stimulated. For acclimation to 50 mm NaCl, the anoxic tissues used only 25 % of the energy that was expended by aerobic tissues. Following return of coleoptiles to aerated non-saline solution, rates of net K+ uptake recovered to those in continuously aerated solution, demonstrating there was little injury during anoxia with 50 mm NaCl. CONCLUSION: Rice seedlings survive anoxia, without the coleoptile incurring significant injury, even with the additional energy demands imposed by NaCl (100 mm when intact, 50 mm when excised). Energy savings were achieved in saline anoxia by less coleoptile growth, reduced ion fluxes as compared to aerobic coleoptiles and apparent energy economic ion transport systems. PMID- 27694333 TI - Waardenburg-Shah Syndrome: a rare case in an Indian child. AB - A 7-year-old male child presented with a history of discolouration of right eye since birth. On examination visual acuity was 6/6 on Snellen's chart in both eyes; anterior segment was within normal limits except for the brilliant blue discolouration of the inferior quadrant and superior quadrant of right iris and left eye iris, respectively. Both eyes had a clear lens and fundus findings were within normal limits. A detailed history from parents revealed that the child had difficulty in hearing and slurring of speech. In addition, the child had repeated episodes of constipation with bilious vomiting during infancy for which a diagnosis of fungal sepsis with Hirschsprung's disease was made and the child had to undergo a mid-sigmoid loop colostomy for that. A diagnosis of Waardenburg- Shah Syndrome was made and the child was referred for hearing and speech rehabilitation. PMID- 27694334 TI - Fever of unknown origin in a patient initially presenting with traveller's diarrhoea. AB - A 17-year-old male presented with diarrhoea and malaise following his return from Kenya and Tunisia. He was managed as a case of traveller's diarrhoea. Stool cultures were negative for pathogenic bacterial growth. Two weeks later he presented with worsening lower back pain. MRI of lumbosacral spine suggested L1 osteomyelitis. CT-guided spinal aspirate grew no organisms and repeat viral serology and blood cultures (including tuberculosis screening) were negative. He was treated with a 6-week course of ceftriaxone. Back pain did not improve and a repeat MRI scan 8 weeks after his antibiotic course indicated progressive changes in L1 extending to L2 with an intradiscal abscess. Repeat CT-guided spinal aspirate grew Salmonella arizonae sensitive to cotrimoxazole and ceftriaxone. He was treated with intravenous ceftriaxone and cotrimoxazole for 12 weeks. A 4 month follow-up MRI scan showed progressive improvement of the L1/L2 discitis with resolution of intradiscal fluid. PMID- 27694335 TI - The impact of critically ill children on paediatric ED medication timeliness. AB - OBJECTIVES: The presence of critically ill patients may impact care for other ED patients. We sought to evaluate whether the presence of a critically ill child was associated with the time to (1) receipt of the first medication among other patients, and (2) administration of diagnosis-specific medications. METHODS: We performed a retrospective cohort study of all paediatric ED visits over 3 years. Patients were exposed if they arrived during the first hour of a critically ill patient's care. The primary outcome was the time from arrival to first medication administration. Secondary outcomes were time to corticosteroids in asthma and time to antibiotics for fever/neutropenia. We modelled times to medication using median regression, adjusting for demographics, arrival time and weekday, and census (number of patients in the ED). RESULTS: We analysed 170 112 visits. Median times to first medication for those exposed to 0, 1 and >1 simultaneous critically ill patients were 90 min (IQR 54-146), 96 min (IQR 58-157) and 113 min (IQR 72-166), respectively (p<0.001). The increase in time to corticosteroids among exposed patients versus unexposed was 6 min (IQR 2-14, p=0.11) and in time to antibiotic for fever/neutropenia was -4 min (IQR -4 to -11, p=0.13). Modelled time to first medication increased 3.1 min (95% CI 0.5 to 5.7) among all exposed patients (p=0.02). Time to first medication increased 15.3 min (95% CI 14.7 to 15.9) for each 10 patient increase in census. CONCLUSIONS: The presence of critically ill patients was associated with a delay in medication administration to others. Census independently predicted medication delays. PMID- 27694338 TI - The healthcare quality improvement partnership national early arthritis audit. PMID- 27694339 TI - Journal of Cell Science is going green. PMID- 27694336 TI - Patient- and clinician-reported outcomes for patients with new presentation of inflammatory arthritis: observations from the National Clinical Audit for Rheumatoid and Early Inflammatory Arthritis. AB - OBJECTIVES: Our aim was to conduct a national audit assessing the impact and experience of early management of inflammatory arthritis by English and Welsh rheumatology units. The audit enables rheumatology services to measure for the first time their performance, patient outcomes and experience, benchmarked to regional and national comparators. METHODS: All individuals >16 years of age presenting to English and Welsh rheumatology services with suspected new-onset inflammatory arthritis were included in the audit. Clinician- and patient-derived outcome and patient-reported experience measures were collected. RESULTS: Data are presented for the 6354 patients recruited from 1 February 2014 to 31 January 2015. Ninety-seven per cent of English and Welsh trusts participated. At the first specialist assessment, the 28-joint DAS (DAS28) was calculated for 2659 (91%) RA patients [mean DAS28 was 5.0 and mean Rheumatoid Arthritis Impact of Disease (RAID) score was 5.6]. After 3 months of specialist care, the mean DAS28 was 3.5 and slightly >60% achieved a meaningful DAS28 reduction. The average RAID score and reduction in RAID score were 3.6 and 2.4, respectively. Of the working patients ages 16-65 years providing data, 7, 5, 16 and 37% reported that they were unable to work, needed frequent time off work, occasionally and rarely needed time off work due to their arthritis, respectively; only 42% reported being asked about their work. Seventy-eight per cent of RA patients providing data agreed with the statement 'Overall in the last 3 months I have had a good experience of care for my arthritis'; <2% disagreed. CONCLUSION: This audit demonstrates that most RA patients have severe disease at the time of presentation to rheumatology services and that a significant number continue to have high disease activity after 3 months of specialist care. There is a clear need for the National Health Service to develop better systems for capturing, coding and integrating information from outpatient clinics, including measures of patient experience and outcome and measures of ability to work. PMID- 27694337 TI - Achievement of NICE quality standards for patients with new presentation of inflammatory arthritis: observations from the National Clinical Audit for Rheumatoid and Early Inflammatory Arthritis. AB - OBJECTIVES: A national audit was performed assessing the early management of suspected inflammatory arthritis by English and Welsh rheumatology units. The aim of this audit was to measure the performance of rheumatology services against National Institute for Health and Care Excellence (NICE) quality standards (QSs) for the management of early inflammatory arthritis benchmarked to regional and national comparators for the first time in the UK. METHODS: All individuals >16 years of age presenting to rheumatology services in England and Wales with suspected new-onset inflammatory arthritis were included in the audit. Information was collected against six NICE QSs that pertain to early inflammatory arthritis management. RESULTS: We present national data for the 6354 patients recruited from 1 February 2014 to 31 January 2015; 97% of trusts and health boards in England and Wales participated in this audit. Only 17% of patients were referred by their general practitioner within 3 days of first presentation. Specialist rheumatology assessment occurred within 3 weeks of referral in 38% of patients. The target of DMARD initiation within 6 weeks of referral was achieved in 53% of RA patients; 36% were treated with combination DMARDs and 82% with steroids within the first 3 months of specialist care. Fifty-nine per cent of patients received structured education on their arthritis within 1 month of diagnosis. In total, 91% of patients had a treatment target set; the agreed target was achieved within 3 months of specialist review in only 27% of patients. Access to urgent advice via a telephone helpline was reported to be available in 96% of trusts. CONCLUSION: The audit has highlighted gaps between NICE standards and delivery of care, as well as substantial geographic variability. PMID- 27694340 TI - Talin2-mediated traction force drives matrix degradation and cell invasion. AB - Talin binds to beta-integrin tails to activate integrins, regulating cell migration, invasion and metastasis. There are two talin genes, TLN1 and TLN2, encoding talin1 and talin2, respectively. Talin1 regulates focal adhesion dynamics, cell migration and invasion, whereas the biological function of talin2 is not clear and, indeed, talin2 has been presumed to function redundantly with talin1. Here, we show that talin2 has a much stronger binding to beta-integrin tails than talin1. Replacement of talin2 Ser339 with Cys significantly decreased its binding to beta1-integrin tails to a level comparable to that of talin1. Talin2 localizes at invadopodia and is indispensable for the generation of traction force and invadopodium-mediated matrix degradation. Ablation of talin2 suppressed traction force generation and invadopodia formation, which were restored by re-expressing talin2 but not talin1. Furthermore, re-expression of wild-type talin2 (but not talin2S339C) in talin2-depleted cells rescued development of traction force and invadopodia. These results suggest that a strong interaction of talin2 with integrins is required to generate traction, which in turn drives invadopodium-mediated matrix degradation, which is key to cancer cell invasion. PMID- 27694341 TI - Development of an Interception Glove Sampler for Skin Exposures to Aromatic Isocyanates. AB - OBJECTIVES: Skin is an important exposure route for isocyanate chemicals and contributes to systemic sensitization. Methods for assessing skin exposure are currently limited and generally rely upon removal (e.g. tape-strip) techniques prone to underestimation. The aim of this study is to (i) develop and field test an interception-based hand exposure sampler to monitor potential skin exposure to isocyanates in the workplace, (ii) to develop an analytical method based on ultra high-performance liquid chromatography-UV absorbance-tandem mass spectrometry (UHPLC-UV-MS/MS) for analyzing glove samples; and (iii) compare it with tape stripping skin sampling method. METHODS: Laboratory investigations assessed different glove materials/fabrics, methods for impregnating with 1-(9 anthracenylmethyl)piperazine (MAP) derivatizing agent, methylene diphenyl diisocyanate (MDI) uptake and recovery, and durability. Following use, gloves were dissected into sections corresponding to different spatial regions (finger, palm) and analyzed using a newly developed UHPLC-UV-MS/MS method capable of differentiating and quantitating different MDI isomers with high sensitivity. Performance of the glove sampler was further assessed in a pilot field study using six workers. RESULTS: A MAP-impregnated thin cotton glove sampler and UHPLC UV-MS/MS analytical method for detecting MDI were successfully developed in laboratory studies. In subsequent field studies, a total of 384 samples from 14 glove pairs identified full-shift exposures ranged from 0.01 to 306 ug of 4,4' MDI/worker for each hand. Surface area adjusted MDI values measured with the glove sampler (0.13-572ng MDI cm-2) were considerably higher (~400-fold) than values obtained with tape stripping. CONCLUSION: A glove sampler and a novel UHPLC-UV-MS/MS analytical method were developed to quantitatively measure MDI skin exposure. The novel interception technique overcomes inherent limitations of removal techniques for measuring isocyanate skin exposure and may be useful in exposure surveillance and future research on isocyanate's health risks. PMID- 27694343 TI - Cross-Sectional and Prospective Associations Between beta-Amyloid in the Brain and Chair Rise Performance in Nondementia Older Adults With Spontaneous Memory Complaints. AB - BACKGROUND: The objectives of this study were to examine the cross-sectional and prospective associations of muscle functional performance as assessed by a chair rise test and brain amyloid load among nondemented older adults with spontaneous memory complaints. METHODS: This is a secondary analysis, with an observational design, using data from the MAPT randomized controlled trial. Individuals assessed for brain amyloid load (florbetapir F18 positron emission tomography) and without clinical dementia (N = 269 aged 75.2+/-4.2 years; 60.2% women) participated in the study. Cortical and regional standard uptake value ratios (SUVRs) were obtained. The main outcome measure was the 5-repetition chair rise performance (maximum speed-higher is better), which was assessed at baseline and at 6, 12, 24, and 36 months. Adjusted multiple linear (cross-sectional) and mixed effect (overtime) regressions were performed. RESULTS: Any of mean cortical (regions of interest) and each regional SUVRs (anterior cingulate, anterior putamen, caudate, hippocampus, medial orbitofrontal cortex, occipital cortex, parietal cortex, pons, posterior cingulate, posterior putamen, precuneus, semioval center, and temporal cortex) were not associated to chair rise after adjustment for multiplicity. These findings were obtained for both cross sectional and prospective associations. CONCLUSIONS: Brain amyloid was not found to be associated to chair rise performance in nondemented older adults with memory complaints. Potential mechanisms on the links, if any, of amyloid load with physical performance are probably not dependent on muscle function. PMID- 27694342 TI - A Tomato Vacuolar Invertase Inhibitor Mediates Sucrose Metabolism and Influences Fruit Ripening. AB - Fruit ripening is a complex process that involves a series of physiological and biochemical changes that ultimately influence fruit quality traits, such as color and flavor. Sugar metabolism is an important factor in ripening, and there is evidence that it influences various aspects of ripening, although the associated mechanism is not well understood. In this study, we identified and analyzed the expression of 36 genes involved in Suc metabolism in ripening tomato (Solanum lycopersicum) fruit. Chromatin immunoprecipitation and gel mobility shift assays indicated that SlVIF, which encodes a vacuolar invertase inhibitor, and SlVI, encoding a vacuolar invertase, are directly regulated by the global fruit ripening regulator RIPENING INHIBITOR (RIN). Moreover, we showed that SlVIF physically interacts with SlVI to control Suc metabolism. Repression of SlVIF by RNA interference delayed tomato fruit ripening, while overexpression of SlVIF accelerated ripening, with concomitant changes in lycopene production and ethylene biosynthesis. An isobaric tags for relative and absolute quantification based quantitative proteomic analysis further indicated that the abundance of a set of proteins involved in fruit ripening was altered by suppressing SlVIF expression, including proteins associated with lycopene generation and ethylene synthesis. These findings provide evidence for the role of Suc in promoting fruit ripening and establish that SlVIF contributes to fruit quality and the RIN mediated ripening regulatory mechanisms, which are of significant agricultural value. PMID- 27694344 TI - Longevity-Associated FOXO3 Genotype and its Impact on Coronary Artery Disease Mortality in Japanese, Whites, and Blacks: A Prospective Study of Three American Populations. AB - Background: We recently reported that protection against coronary artery disease (CAD) mortality is the major contributor to longer life associated with FOXO3 genotype. The present study examined this relation in more detail. Methods: We performed a 15-year observational study of 3,584 older American men of Japanese ancestry from the Kuakini Honolulu Heart Program cohort and 1,595 White and 1,067 Black elderly individuals from the Health Aging and Body Composition study. Results: Multivariate Cox regression models demonstrated that carriage of the longevity-associated G allele of FOXO3 single nucleotide polymorphisms rs2802292 was a protective factor against CAD mortality in all three populations. In Japanese and Whites, but not in Blacks, the protective effect of the G allele was little changed in models adjusted for other major risk factors. Population attributable risk (PAR) models found that the nonprotective TT genotype contributed 15%, 9%, and 3% to CAD mortality risk in Japanese, White, and Black Americans, respectively, and was one of the top three contributing factors to CAD mortality. In Japanese, this effect size was comparable with hypertension (15%), but in Whites and Blacks PAR for hypertension was higher (29% and 26%, respectively). G-allele carriers had lower plasma TNF-alpha than noncarriers, suggesting inflammation as a potential mediating factor for CAD mortality risk. Conclusion: FOXO3 genotype is an important risk factor for CAD mortality in older populations. More research is needed to identify potential mechanisms and targets for intervention. PMID- 27694345 TI - Impact of Feeding on Contaminated Prey on the Life Parameters of Nesidiocoris Tenuis (Hemiptera: Miridae) Adults. AB - Insecticide selectivity to natural enemies is an important concern in integrated pest management programs. Although there is a wide range of information concerning pesticide lethal and sublethal effects on contaminated surfaces, little is known when the route of exposure occurs at a trophic level. This study evaluates this route of pesticide intake on the omnivorous predator Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) for the first time. Under laboratory conditions, prey treated with six insecticides (flubendiamide, spirotetramat, deltamethrin, flonicamid, metaflumizone, and sulfoxaflor) were offered to N. tenuis adults for 3 days. Mortality (24, 48, and 72 h after treatment), offspring production (third until eighth day) and longevity were documented. Metaflumizone and sulfoxaflor were classified as moderately harmful products because although the percentage of mortality was only 28 and 36%, respectively, both products caused a severe decrease in offspring production and longevity. Flonicamid and flubendiamide were classified as slightly harmful products; although they did not have a lethal effect, sublethal impact was important on the parameters studied. Spirotetramat and deltamethrin were insecticides categorized as harmless. This information could be useful for selecting the most appropriate insecticides to control pests in tomato crops in which N. tenuis is a relevant biological control agent. PMID- 27694347 TI - Final transitions to place of death: patients and families wishes. AB - Purpose: This four-country study (Belgium, the Netherlands, Italy and Spain) examines prevalence and types of final transitions between care settings of cancer patients and the extent to which patient/family wishes are cited as a reason for the transition. Methods: Data were collected from the EUROSENTI-MELC study over a 2-year period. General practitioners within existing Sentinel Networks registered weekly all deaths of patients within practices using a standardized questionnaire. This registration included place of care in the final 3 months and wishes for the final transition to place of death. All non-sudden deaths due to cancer (+18 years) were included in the analyses. Results: We included 2048 non-sudden cancer deaths; 63% of patients had at least one transition between care settings in the final 3 months of life. 'Hospital death from home' (25-55%) and 'home death from hospital' (16-30%) were the most frequent types of final transitions in all countries. Patients' or families' wishes were mentioned as a reason for a final transition in 5-27% (P < 0.001) and 10-22% (P = 0.002) across countries. Conclusions: 'Hospital deaths from home' is the most prevalent final transition in three of four countries studied, in a significant minority of cases because of patient/family wishes. PMID- 27694346 TI - Insect Visitors and Potential Pollinators of Orchis militaris (Orchidaceae) in Southern Belgium. AB - As part of a research project on the food deception strategy in Orchis militaris (L.), the objective of this study was to identify insect visitors and potential pollinators of this orchid species in Belgium. In 2013, insects were collected over 2 d per site in five localities distributed in Southern Belgium (Wallonia). A total of 104 insects belonging to 49 species were caught. Dipterans were the most abundant visitors (50% of total specimens), followed by Hymenopterans (32%). Rhingia campestris Meigen, Bombylius venosus Mikan, Apis mellifera (L.), and Bombus lapidarius (L.) were the most abundant species. Only five specimens bore one to more than 10 pollinia: four honeybees (A. mellifera) and one bumblebee worker (B. lapidarius). These two species should be considered as potential pollinators in the study area, but probably not confirmed ones. PMID- 27694348 TI - Implementing extreme weather event advice and guidance in English public health systems. AB - Background: Extreme weather events (EWEs) can significantly impact on mortality and morbidity in the UK. How EWE guidance is disseminated and applied across health and social care systems, at the local, operational level, is not well understood. Methods: This exploratory study develops tools and resources to assist local stakeholders to cascade national 'all weather' EWE guidance across local systems. These resources are also used to evaluate the local interpretation and implementation of this advice and guidance within three local authority areas. In total, five discussion group meetings were held and 45 practitioners took part in the study. A thematic analysis was conducted. Results: The main themes emerging from the analysis related to awareness of PHE guidance for EWE preparedness, data sharing feasibility, community engagement, specific conditions in remote rural areas and capacity of frontline staff. Conclusions: The relative difficulty in finding where the study 'best fits' on local stakeholders' agendas suggests that year-round and preparedness planning for EWEs may not have been considered a high priority in participating areas. This study adds to the relatively limited evidence internationally concerning the practical implementation at local level of national adaptation advice and guidance and potential barriers to achieving this. PMID- 27694349 TI - Using mobile technology to optimize disease surveillance and healthcare delivery at mass gatherings: a case study from India's Kumbh Mela. AB - Background: Planning for mass gatherings often includes temporary healthcare systems to address the needs of attendees. However, paper-based record keeping has traditionally precluded the timely application of collected clinical data for epidemic surveillance or optimization of healthcare delivery. We evaluated the feasibility of harnessing ubiquitous mobile technologies for conducting disease surveillance and monitoring resource utilization at the Allahabad Kumbh Mela in India, a 55-day festival attended by over 70 million people. Methods: We developed an inexpensive, tablet-based customized disease surveillance system with real-time analytic capabilities, and piloted it at five field hospitals. Results: The system captured 49 131 outpatient encounters over the 3-week study period. The most common presenting complaints were musculoskeletal pain (19%), fever (17%), cough (17%), coryza (16%) and diarrhoea (5%). The majority of patients received at least one prescription. The most common prescriptions were for antimicrobials, acetaminophen and non-steroidal anti-inflammatory drugs. There was great inter-site variability in caseload with the busiest hospital seeing 650% more patients than the least busy hospital, despite identical staffing. Conclusions: Mobile-based health information solutions developed with a focus on user-centred design can be successfully deployed at mass gatherings in resource-scarce settings to optimize care delivery by providing real-time access to field data. PMID- 27694350 TI - Optimization of cell lines as tumour models by integrating multi-omics data. AB - Cell lines are widely used as in vitro models of tumorigenesis. However, an increasing number of researchers have found that cell lines differ from their sourced tumour samples after long-term cell culture. The application of unsuitable cell lines in experiments will affect the experimental accuracy and the treatment of patients. Therefore, it is imperative to identify optimal cell lines for each cancer type. Here, we review the methods used to evaluate cell lines since 2005. Furthermore, gene expression, copy number and mutation profiles from The Cancer Genome Atlas and the Cancer Cell Line Encyclopedia are used to calculate similarity between tumours and cell lines. Then, the ideal cell lines to use for experiments for eight types of cancers are found by combining the results with Gene Ontology functional similarity. After verification, the optimal cell lines have the same genomic characteristics as their homologous tumour samples. The contaminated cell lines identified in previous research are also determined to be unsuitable in vitro cancer models here. Moreover, our study suggests that some of the commonly used cell lines are not suitable cancer models. In summary, we provide a reference for ideal cell lines to use in in vitro experiments and contribute to improving the accuracy of future cancer research. Furthermore, this research provides a foundation for identifying more effective treatment strategies. PMID- 27694353 TI - The Toxic Wake of Rudeness: Why It Matters.

AB - More than one-third of the US adult population and 17% of the youth are now obese, and obesity is associated with more than $147 billion a year in health care costs. Critical care nurses should understand the physiological differences and practice guidelines for patients with a body mass index greater than 30. The ABCD approach encompasses key clinical concepts in the management of critically ill obese and morbidly obese patients, including management of airways and breathing, minimizing nurses' back and other injuries, increasing awareness of bias, circulation problems, risks of decubitus ulcers and other skin breakdown, differences in drug calculations and metabolism, limitations in diagnostic equipment and imaging, diet and nutritional recommendations, and concerns with durable medical equipment.

After the esophageal pressure is measured, the corresponding pleural pressure in the thorax can be projected, enabling lung-thorax compliance to be partitioned into chest-wall compliance and lung compliance. The esophageal balloon allows determination of transpulmonary pressures and a correspondingly individually tailored approach to respiratory care, such as patient-specific titration of positive end-expiratory pressure for patients with extrapulmonary acute respiratory distress syndrome. Esophageal balloon monitoring provides critical information for selecting ventilation strategies to use in patients with acute respiratory distress syndrome. PMID- 27694351 TI - A systematic evaluation of normalization methods in quantitative label-free proteomics. AB - To date, mass spectrometry (MS) data remain inherently biased as a result of reasons ranging from sample handling to differences caused by the instrumentation. Normalization is the process that aims to account for the bias and make samples more comparable. The selection of a proper normalization method is a pivotal task for the reliability of the downstream analysis and results. Many normalization methods commonly used in proteomics have been adapted from the DNA microarray techniques. Previous studies comparing normalization methods in proteomics have focused mainly on intragroup variation. In this study, several popular and widely used normalization methods representing different strategies in normalization are evaluated using three spike-in and one experimental mouse label-free proteomic data sets. The normalization methods are evaluated in terms of their ability to reduce variation between technical replicates, their effect on differential expression analysis and their effect on the estimation of logarithmic fold changes. Additionally, we examined whether normalizing the whole data globally or in segments for the differential expression analysis has an effect on the performance of the normalization methods. We found that variance stabilization normalization (Vsn) reduced variation the most between technical replicates in all examined data sets. Vsn also performed consistently well in the differential expression analysis. Linear regression normalization and local regression normalization performed also systematically well. Finally, we discuss the choice of a normalization method and some qualities of a suitable normalization method in the light of the results of our evaluation. PMID- 27694356 TI - Cardiovascular Disease and HIV: Pathophysiology, Treatment Considerations, and Nursing Implications. AB - HIV infection has progressed from an acute, terminal disease to a chronic illness with cardiovascular disease as the leading cause of death among persons living with HIV. As persons living with HIV infection continue to become older, traditional risk factors for atherosclerosis compounded by the pathophysiological effects of HIV infection and antiretroviral therapy markedly increase the risk for cardiovascular disease. Further, persons living with HIV are also at high risk for cardiomyopathy. Critical care nurses must recognize the risk factors for cardiovascular disease and the pathophysiology and complex treatment options in order to manage care of these patients and facilitate multidisciplinary collaboration. Two case studies are used to highlight the treatment options and nursing considerations associated with cardiovascular disease among persons living with HIV. PMID- 27694357 TI - Understanding the Hybrid Stage I Approach for Hypoplastic Left Heart Syndrome. AB - Hybrid stage I palliation combines cardiothoracic surgery and interventional transcatheter procedures for treatment of hypoplastic left heart syndrome. The approach is an alternative to the Norwood procedure, the traditional first stage of surgical palliation. Hybrid stage I palliation involves placing bilateral branch pulmonary artery bands and a patent ductus arteriosus stent through a median sternotomy, performed without cardiopulmonary bypass. The purpose of the bands is to control blood flow to the lungs and protect the pulmonary bed while the stent sustains systemic cardiac output. A balloon atrial septostomy is performed to create an atrial septal defect for unobstructed blood flow from the left atrium to the right atrium. The second stage of palliative surgery is the comprehensive stage II, which incorporates removal of the stent and pulmonary artery bands, atrial septectomy, anastomosis of the diminutive ascending aorta to the main pulmonary artery, aortic arch augmentation, and bidirectional cavopulmonary anastomosis. The traditional Fontan procedure completes the series of palliation. PMID- 27694359 TI - Good Witch or Bad Witch? PMID- 27694358 TI - Clarification and Mitigation of Ethical Problems Surrounding Withdrawal of Extracorporeal Membrane Oxygenation. AB - Extracorporeal membrane oxygenation (ECMO) is temporary life-support technology that provides time to rest the cardiac and respiratory system of critically ill people with acute, reversible medical conditions. Health care providers face emotional and challenging situations, where death may result, when withdrawing ECMO. A deepening of understanding of the ethical issues involved can aid clinicians in handling such difficult situations, leading to a possible mitigation of the moral problems. Toward this end, the ethical issues raised in the consideration of ECMO withdrawal are analyzed with respect to the ethical principles and concepts of autonomy, nonmaleficence/beneficence, medical futility, moral distress, and justice. In particular, these issues are considered in relation to how they affect and can be addressed by staff nurses and advanced practice nurses in the intensive care unit. Advanced practice nurses in particular can represent the voice of nurses to promote a healthier workplace in situations of moral distress related to stopping ECMO life-support technology and in developing clear and consistent guidelines for ceasing ECMO treatment, all leading toward clarification and mitigation of the ethical problems surrounding the withdrawal of this critical technology.

AB - BACKGROUND: Ventilator-associated pneumonia (VAP), one of the most common hospital-acquired infections, has a high mortality rate. OBJECTIVES: To evaluate the incidence of VAP in a multidisciplinary intensive care unit and to examine the effects of the implementation of ventilator bundles and staff education on its incidence. METHODS: A 24-month-long before/after study was conducted, divided into baseline, intervention, and postintervention periods. VAP incidence and rate, the microbiological profile, duration of mechanical ventilation, and length of stay in the intensive care unit were recorded and compared between the periods. RESULTS: Of 1097 patients evaluated, 362 met the inclusion criteria. The baseline VAP rate was 21.6 per 1000 ventilator days. During the postintervention period, it decreased to 11.6 per 1000 ventilator days (P = .01). Length of stay in the intensive care unit decreased from 36 to 27 days (P = .04), and duration of mechanical ventilation decreased from 26 to 21 days (P = .06). CONCLUSIONS: VAP incidence was high in a general intensive care unit in a Greek hospital. However, implementation of a ventilator bundle and staff education has decreased both VAP incidence and length of stay in the unit.

PMID- 27694364 TI - Educating Health Care Providers in Treatment of Patients With Ebola Virus Disease. AB - Nurses manage patients with common infectious diseases by following institutional guidelines based on expert advice, evidence in the literature, and a wealth of experience. Today nurses are challenged to provide care to patients with multidrug-resistant organisms and virulent infectious diseases such as Ebola virus disease. Management of some patients with virulent infectious diseases occurs in the context of minimal experience with the pathogen, course of infection, diagnostics, nursing care, and treatment. Limited evidence exists in the US or international literature about direct nursing care of patients with virulent infectious diseases in the community, clinic, or hospital. Workplaces may have insufficient supplies, equipment, and knowledge of the management of patients with these diseases. At the National Institutes of Health Clinical Center in Bethesda, Maryland, nursing education strategies for enhanced experiential learning are used to prepare staff to care for patients with virulent infectious diseases, especially Ebola virus disease. PMID- 27694367 TI - Single and mixed feline lungworm infections: clinical, radiographic and therapeutic features of 26 cases (2013-2015). AB - Objectives The aim of this study was to retrospectively describe clinical, radiographic and therapeutic features of feline lungworm infection. Methods Medical records of cats with lungworm diagnosis, thoracic radiography and without concurrent diseases between 2013 and 2015 were reviewed. Collection of data included physical examination, haematology, serum biochemistry, therapy with a variety of anthelmintics and outcomes. Results Thirty-seven records were recovered and 26 were included in the study. Single infections by Aelurostrongylus abstrusus (n = 15), Troglostrongylus brevior (n = 3) and Capillaria aerophila (n = 1) and coinfections by T brevior/ A abstrusus (n = 6) and T brevior/ C aerophila (n = 1) were diagnosed. The most common respiratory signs were coughing (n = 12), increased vesicular sounds (n = 10), dyspnoea (n = 9), such as laboured breathing, orthopnoea or open-mouth breathing, and tachypnoea (n = 6). Two cats were subclinically infected. The most common laboratory abnormality was anaemia (n = 7). Radiographic patterns recorded were interstitial (n = 24), bronchial (n = 21), alveolar (n = 10) and vascular (n = 2). Twenty-five cats had a complete recovery within 2-6 weeks of therapy. One kitten died 7 days after the diagnosis. Conclusions and relevance Lungworms should always be included in the differential diagnosis in cats living in endemic areas and presenting with respiratory signs and radiographic abnormalities. A copromicroscopic examination should be considered as the first diagnostic step for all cats at risk of lungworm infections. In most cases, timely therapy with a variety of anthelmintics guarantees recovery. PMID- 27694368 TI - Placement of subcutaneous ureteral bypasses without fluoroscopic guidance in cats with ureteral obstruction: 19 cases (2014-2016). AB - Objectives The purpose of this study was to describe the perioperative and postoperative complications as well as short-term and long-term outcomes in cats with ureteral obstructions treated by placement of a subcutaneous ureteral bypass (SUB) device without imaging control. The second objective of this study was to compare cats treated by SUB device with cats treated by traditional surgical intervention. Methods Data were obtained retrospectively from the medical records (2014-2016) of cats that underwent SUB placement (SUB cats) and cats that underwent traditional ureteral surgery (C cats). Results Nineteen SUB devices were placed without fluoroscopic, radiographic or ultrasonographic guidance in 13 cats. Fifteen traditional interventions (ureterotomy and neoureterocystostomy) were performed in 11 cats. Successful placement of the SUB device was achieved in all cats with only one major intraoperative complication (kinking of the kidney catheter) and one minor intraoperative complication (misplacement of the kidney catheter). Eleven SUB cats recovered from the surgical procedure; two SUB cats and three C cats died during the anaesthesia recovery period. Postoperative SUB complications included anaemia (n = 2), urinary tract infection (UTI) (n = 4), non-infectious cystitis (n = 5) and SUB device obstruction (n = 1). Postoperative traditional surgery complications included anaemia (n = 7), UTIs (n = 6), non infectious cystitis (n = 1), re-obstruction (n = 4) and ureteral stricture (n = 1). Median postoperative duration of hospitalisation (3 days) was significantly shorter for SUB cats than for C cats ( P = 0.013). Ten SUB cats (76.9%) and four C cats (40%) were still alive at a median follow-up of 225 days and 260 days, respectively. Owners were completely (90%) or mostly (10%) satisfied with the SUB device placement. Conclusions and relevance SUB device placement appears to be an effective and safe option for treating ureteral obstruction in cats, and this study has shown that fluoroscopic guidance is not essential in all cases. PMID- 27694369 TI - Increased detection of Dirofilaria immitis antigen in cats after heat pretreatment of samples. AB - Objectives To determine whether pretreating diagnostic samples with heat increases the detection of Dirofilaria immitis antigen in adult cats, we evaluated feline serum and plasma samples collected in heartworm-endemic areas of the southern United States. Methods Commercial microtiter well assays for detection of D immitis antigen were used to evaluate serum or plasma samples from 385 shelter and free-roaming cats from the southcentral and southeastern United States before and after heat treatment; commercial antibody tests were performed on a subset of samples. Results Prior to sample heat treatment, 1/220 (0.5%) shelter cats and 4/165 (2.4%) free-roaming cats had detectable D immitis antigen. After heat pretreatment, the detection rate increased to 13/220 (5.9%) and 13/165 (7.9%), respectively. Antibody reactive to D immitis was significantly more common ( P <0.001) in the serum of cats that were antigen positive after heat treatment (10/13; 76.9%) than serum from cats that remained antigen negative after heat treatment (22/163; 13.5%). Conclusions and relevance Heat pretreatment of feline samples increased antigen detection by commercial assays for D immitis and improved overall concordance of antigen and antibody test results in antigen positive samples in this population. Although further work to investigate the specificity of D immitis antigen assays when using pre-treated samples is warranted, this approach may be useful in the diagnosis of heartworm infection in individual cats and may increase the accuracy of surveys based on antigen detection. PMID- 27694370 TI - Cohort Differences in Cognitive Aging in the Longitudinal Aging Study Amsterdam. AB - Objectives: This study aims to examine cohort differences in cognitive performance and rates of change in episodic memory, processing speed, inductive reasoning, and general cognitive performance and to investigate whether these cohort effects may be accounted for by education attainment. Method: The first cohort (N = 705) was born between 1920 and 1930, whereas the second cohort (N = 646) was born between 1931 and 1941. Both birth cohorts were aged 65 to 75 years at baseline and were followed up 3 and 6 years later. Data were analyzed using linear mixed models. Results: The later born cohort had better general cognitive performance, inductive reasoning, and processing speed at baseline, but cohort differences in inductive reasoning and general cognitive performance disappeared after adjusting for education. The later born cohort showed steeper decline in processing speed. Memory decline was steeper in the earlier born cohort but only from Time 1 to Time 3 when the same memory test was administered. Education did not account for cohort differences in cognitive decline. Discussion: The later born cohort showed better initial performance in certain cognitive abilities, but no better preservation of cognitive abilities overtime compared with the earlier born cohort. These findings carry implications for healthy cognitive aging. PMID- 27694371 TI - From Classroom to Capitol: Building Advocacy Capacity Through State-Level Advocacy Experiences.

PMID- 27694372 TI - The EDIC Method: An Engaging and Comprehensive Approach for Creating Health Department Workforce Development Plans. AB - In 2013, the Nebraska Department of Health & Human Services, Division of Public Health (Nebraska's State Health Department); and the University of Nebraska Medical Center, College of Public Health developed a comprehensive approach to assess workforce training needs. This article outlines the method used to assess the education and training needs of Division staff, and develop comprehensive workforce development plans to address those needs. The EDIC method (Engage, Develop, Identify, and Create) includes the following four phases: (1) Engage Stakeholders, (2) Develop Assessment, (3) Identify Training Needs, and (4) Create Development Plans. The EDIC method provided a process grounded in science and practice, allowed input, and produced buy-in from staff at all levels throughout the Division of Public Health. This type of process provides greater assurance that the most important gaps in skills and competencies will be identified. Although it is a comprehensive approach, it can be replicated at the state or local level across the country. PMID- 27694373 TI - Micro and nanoparticles as possible pathogenetic co-factors in mixed cryoglobulinemia. AB - BACKGROUND: Mixed cryoglobulinemia (MC) is a rare multisystem disease whose aetiopathogenesis is not completely understood. Hepatitis C virus (HCV) infection may have a causative role, and genetic and/or environmental factors may also contribute. AIMS: To investigate the presence and possible role of environmental agents in MC. METHODS: We recruited 30 HCV-infected MC patients with different clinical manifestations and a control group of 30 healthy, sex-/age-matched volunteers. We collected serum samples from each patient and incubated at 4 degrees C for 7 days to obtain cryoprecipitate samples. We used environmental scanning electron microscopy (ESEM) and energy dispersive X-ray spectroscopy microanalysis to verify the presence of microparticles (MPs) and nanoparticles (NPs) in serum and cryoprecipitate samples. We evaluated environmental exposure using a medical and occupational history questionnaire for each subject. RESULTS: MC patients had a significantly higher risk of occupational exposure (OR 5.6; 95% CI 1.84-17.50) than controls. ESEM evaluation revealed a significantly higher concentration, expressed as number of positive spots (NS), of serum inorganic particles in MC patients compared with controls (mean NS 18, SD = 16 versus NS 5.4, SD = 5.1; P < 0.05). Cryoprecipitate samples of MC patients showed high concentrations of inorganic particles (mean NS 49, SD = 19). We found a strong correlation between NS and cryocrit (i.e. percentage of cryoprecipitate/total serum after centrifugation at 4 degrees C) levels (P < 0.001). CONCLUSIONS: In addition to HCV infection, MPs and NPs might play an important role in the aetiopathogenesis of MC. PMID- 27694374 TI - Challenging cognitive cases among physician populations: case vignettes and recommendations. AB - BACKGROUND: Physicians are not immune to cognitive impairment. Because of the risks created by practising doctors with these issues, some have suggested developing objective, population-specific measures of evaluation and screening guidelines to assess dysfunction. However, there is very little published information from which to construct such resources. AIMS: To highlight the presentation characteristics and provide evaluation recommendations specific to the needs of physicians with actual or presumed cognitive impairment. METHODS: A retrospective database and chart review of cognitively impaired doctors who presented to a physician health programme (PHP). Complex cases were highlighted using simple descriptives and clinical vignettes. RESULTS: A total of 124 cases were included. Clients presented with a variety of issues other than cognitive concerns. We identified four principal domains of impairment: (i) diseases of (or in) the brain (48%); (ii) mood/ anxiety disorders or treatment side effects (28%); (iii) substance use (9%) and (iv) traumatic brain injury (7%). Age was not a good predictor of impairment and brief screening using the Montreal Cognitive Assessment demonstrated a ceiling effect with this cohort. Although many clients underwent some type of professional or personal transition, impairment did not necessarily indicate worse functioning after care. CONCLUSIONS: Physician cognitive evaluations should consider a variety of secondary sources of information, particularly vocational performance reports. It may take time before cognitive impairment can be diagnosed or ruled-out in this population. Prior assumptions, especially for non-cognitive referrals, can lead to inaccurate diagnosis and referrals. PHPs must manage cognitive cases carefully, not only in their clinical complexity but also in their psychosocial aspects. PMID- 27694375 TI - Squatting-induced bilateral peroneal nerve palsy in a sewer pipe worker. AB - Compression neuropathy of the common peroneal nerve (CPN) at the fibula head is a common condition, but it has not attracted attention in working environments. Here, we report a 38-year-old sewer pipe worker who presented with bilateral CPN palsy following 6h working with a squatting posture in a narrow sewer pipe. During the work, he could not stretch his legs sufficiently because of the confined space. His symptoms deteriorated with repetition of the same work for 1 week. Motor nerve conduction study showed conduction block at the fibula head of bilateral CPNs, compatible with compression neuropathy at this lesion. Three months after cessation of work requiring the causative posture, his symptoms and neurophysiological abnormalities had resolved completely. Almost all seven of his co-workers presented transiently with similar and milder symptoms, although one showed CPN palsy for 6 months. Prolonged squatting posture in a confined space causes acute compression neuropathy at the fibula head in the CPN. More attention should be paid to 'confined space worker's compression neuropathy'. PMID- 27694377 TI - Obesity prevalence and accuracy of BMI-defined obesity in Russian firefighters. AB - BACKGROUND: No data exist on obesity or the accuracy of body mass index (BMI) in Russian Federation firefighters. AIMS: To determine the prevalence of obesity and rates of misclassification of BMI-based obesity status. METHODS: Career firefighters in the Moscow region completed anthropometric assessments including height, weight, BMI, body fat per cent (BF%) and waist circumference (WC). Using these three methods, we defined obesity as BMI >=30, BF% >25 and WC >102, respectively. RESULTS: The study group consisted of 167 male firefighters. Obesity prevalence was 22% for BMI [95% confidence interval (CI) 16.9-28.5], 60% for BF% (95% CI 52.5-67.3) and 28% for WC (95% CI 21.3-34.9). False positive rates for BMI-based obesity status were low, with 3% (95% CI -1.1 to 7.1) and 6% (95% CI 1.6-9.9) of non-obese participants defined by BF% and WC standards misidentified as obese using BMI. However, 65% (95% CI 55.7-77.4) of BF%-defined obese participants and 36% (95% CI 22.5-49.9) of WC-defined obese participants were misclassified as non-obese using BMI (i.e. false negatives). CONCLUSIONS: Rates of BMI-based obesity in Russian male firefighters were similar to that of males in the general Russian adult male population. Compared with BF% or WC standards, BMI-based obesity classi- fication produced low rates of false positives but demonstrated high rates of false negatives. PMID- 27694376 TI - Shift work, mental distress and job satisfaction among Palestinian nurses. AB - BACKGROUND: Associations between shift work (SW) schedules, mental distress and job satisfaction have never been completely described. AIMS: To examine gender specific associations of SW with mental distress and job satisfaction in nurses in Hebron District, Palestine, in 2012. METHODS: Detailed information on work schedules (day versus shift), socio-demographic status, mental distress (General Health Questionnaire, GHQ-30) and job satisfaction (Generic Job Satisfaction Scale) in nurses employed in Hebron District, Palestine, was obtained through a questionnaire survey. Associations of SW and outcomes were examined by linear regression analysis. RESULTS: Of 372 nurses eligible for the study, 309 and 338 completed surveys regarding mental distress and job satisfaction, respectively. The sample comprised 62% women and 38% men. After adjusting for covariates, women working shifts reported significantly higher levels of mean mental distress [beta coefficient 3.6; 95% confidence interval (CI) 0.3-7.0] compared with women working regular day shifts. Men working shifts reported significantly lower levels of job satisfaction (-3.3; 95% CI -6.2 to -0.5) than men working regular day shifts. Women reported higher levels of mental distress than men, but this was unrelated to work schedule. CONCLUSIONS: In this study, nurses working shifts reported higher levels of mental distress and lower levels of job satisfaction, although these associations were weaker when adjusted for potential covariates. There was no evidence of a gender differential in the association between SW and mental distress and job satisfaction. PMID- 27694378 TI - Incidence of tuberculosis among nurses and healthcare assistants in France. AB - BACKGROUND: Health care workers (HCWs) are considered to be at higher risk of tuberculosis (TB) than the general population. However, a decreasing incidence in the general population as well as improvement in preventive measures in hospitals has reduced the risk for HCWs. AIMS: To quantify the actual incidence of TB in nurses and health care assistants in a low-incidence country. METHODS: We performed a retrospective study of 80 hospitals throughout France, employing 233389 health care staff (physicians excluded). We calculated the number of pulmonary TB cases over 3 years (700166 person-years) and the total number of staff members in each job category (nurses, health care assistants, administrative staff) in each hospital, to calculate the incidence. RESULTS: Overall, the incidence rate varied between 1.27 and 6/100000 for administrative staff and nurses, respectively (non-significant difference). The incidence varied according to the geographical area. However, the incidence in nurses and health care assistants was not different from the general population (7.5/100000). CONCLUSIONS: In a low-incidence country, such as France, the implementation of measures to prevent occupational TB among HCWs has been effective. These preventive measures should be maintained but medical follow-up could be revised. PMID- 27694379 TI - Cancer Drugs Remain Hot Targets.

PMID- 27694388 TI - Secondary structure model of the naked segment 7 influenza A virus genomic RNA. AB - The influenza A virus (IAV) genome comprises eight negative-sense viral (v)RNA segments. The seventh segment of the genome encodes two essential viral proteins and is specifically packaged alongside the other seven vRNAs. To gain insights into the possible roles of RNA structure both within and without virions, a secondary structure model of a naked (protein-free) segment 7 vRNA (vRNA7) has been determined using chemical mapping and thermodynamic energy minimization. The proposed structure model was validated using microarray mapping, RNase H cleavage and comparative sequence analysis. Additionally, the detailed structures of three vRNA7 fragment constructs - comprising independently folded subdomains - were determined. Much of the proposed vRNA7 structure is preserved between IAV strains, suggesting their importance in the influenza replication cycle. Possible structure rearrangements, which allow or preclude long-range RNA interactions, are also proposed. PMID- 27694387 TI - The topogenic function of S4 promotes membrane insertion of the voltage-sensor domain in the KvAP channel. AB - Voltage-dependent K+ (KV) channels control K+ permeability in response to shifts in the membrane potential. Voltage sensing in KV channels is mediated by the positively charged transmembrane domain S4. The best-characterized KV channel, KvAP, lacks the distinct hydrophilic region corresponding to the S3-S4 extracellular loop that is found in other K+ channels. In the present study, we evaluated the topogenic properties of the transmembrane regions within the voltage-sensing domain in KvAP. S3 had low membrane insertion activity, whereas S4 possessed a unique type-I signal anchor (SA-I) function, which enabled it to insert into the membrane by itself. S4 was also found to function as a stop transfer signal for retention in the membrane. The length and structural nature of the extracellular S3-S4 loop affected the membrane insertion of S3 and S4, suggesting that S3 membrane insertion was dependent on S4. Replacement of charged residues within the transmembrane regions with residues of opposite charge revealed that Asp72 in S2 and Glu93 in S3 contributed to membrane insertion of S3 and S4, and increased the stability of S4 in the membrane. These results indicate that the SA-I function of S4, unique among K+ channels studied to date, promotes the insertion of S3 into the membrane, and that the charged residues essential for voltage sensing contribute to the membrane-insertion of the voltage sensor domain in KvAP. PMID- 27694385 TI - Tumor Cell-Independent Estrogen Signaling Drives Disease Progression through Mobilization of Myeloid-Derived Suppressor Cells. AB - : The role of estrogens in antitumor immunity remains poorly understood. Here, we show that estrogen signaling accelerates the progression of different estrogen insensitive tumor models by contributing to deregulated myelopoiesis by both driving the mobilization of myeloid-derived suppressor cells (MDSC) and enhancing their intrinsic immunosuppressive activity in vivo Differences in tumor growth are dependent on blunted antitumor immunity and, correspondingly, disappear in immunodeficient hosts and upon MDSC depletion. Mechanistically, estrogen receptor alpha activates the STAT3 pathway in human and mouse bone marrow myeloid precursors by enhancing JAK2 and SRC activity. Therefore, estrogen signaling is a crucial mechanism underlying pathologic myelopoiesis in cancer. Our work suggests that new antiestrogen drugs that have no agonistic effects may have benefits in a wide range of cancers, independently of the expression of estrogen receptors in tumor cells, and may synergize with immunotherapies to significantly extend survival. SIGNIFICANCE: Ablating estrogenic activity delays malignant progression independently of the tumor cell responsiveness, owing to a decrease in the mobilization and immunosuppressive activity of MDSCs, which boosts T-cell dependent antitumor immunity. Our results provide a mechanistic rationale to block estrogen signaling with newer antagonists to boost the effectiveness of anticancer immunotherapies. Cancer Discov; 7(1); 72-85.

PMID- 27694386 TI - Acquired METD1228V Mutation and Resistance to MET Inhibition in Lung Cancer. AB - : Amplified and/or mutated MET can act as both a primary oncogenic driver and as a promoter of tyrosine kinase inhibitor (TKI) resistance in non-small cell lung cancer (NSCLC). However, the landscape of MET-specific targeting agents remains underdeveloped, and understanding of mechanisms of resistance to MET TKIs is limited. Here, we present a case of a patient with lung adenocarcinoma harboring both a mutation in EGFR and an amplification of MET, who after progression on erlotinib responded dramatically to combined MET and EGFR inhibition with savolitinib and osimertinib. When resistance developed to this combination, a new MET kinase domain mutation, D1228V, was detected. Our in vitro findings demonstrate that METD1228V induces resistance to type I MET TKIs through impaired drug binding, while sensitivity to type II MET TKIs is maintained. Based on these findings, the patient was treated with erlotinib combined with cabozantinib, a type II MET inhibitor, and exhibited a response. SIGNIFICANCE: With several structurally distinct MET inhibitors undergoing development for treatment of NSCLC, it is critical to identify mechanism-based therapies for drug resistance. We demonstrate that an acquired METD1228V mutation mediates resistance to type I, but not type II, MET inhibitors, having therapeutic implications for the clinical use of sequential MET inhibitors.

PMID- 27694389 TI - Membrane protein extraction and purification using styrene-maleic acid (SMA) copolymer: effect of variations in polymer structure. AB - The use of styrene-maleic acid (SMA) copolymers to extract and purify transmembrane proteins, while retaining their native bilayer environment, overcomes many of the disadvantages associated with conventional detergent-based procedures. This approach has huge potential for the future of membrane protein structural and functional studies. In this investigation, we have systematically tested a range of commercially available SMA polymers, varying in both the ratio of styrene and maleic acid and in total size, for the ability to extract, purify and stabilise transmembrane proteins. Three different membrane proteins (BmrA, LeuT and ZipA), which vary in size and shape, were used. Our results show that several polymers, can be used to extract membrane proteins, comparably to conventional detergents. A styrene:maleic acid ratio of either 2:1 or 3:1, combined with a relatively small average molecular mass (7.5-10 kDa), is optimal for membrane extraction, and this appears to be independent of the protein size, shape or expression system. A subset of polymers were taken forward for purification, functional and stability tests. Following a one-step affinity purification, SMA 2000 was found to be the best choice for yield, purity and function. However, the other polymers offer subtle differences in size and sensitivity to divalent cations that may be useful for a variety of downstream applications.

PMID- 27694391 TI - Using Targeted Sequencing of Paralogous Sequences for Noninvasive Detection of Selected Fetal Aneuploidies. AB - BACKGROUND: Current methods for noninvasive prenatal testing (NIPT) ascertain fetal aneuploidies using either direct counting measures of DNA fragments from specific genomic regions or relative measures of single nucleotide polymorphism frequencies. Alternatively, the ratios of paralogous sequence pairs were predicted to reflect fetal aneuploidy. We developed a NIPT assay that uses paralog sequences to enable noninvasive detection of fetal trisomy 21 (T21) and trisomy 18 (T18) using cell-free DNA (cfDNA) from maternal plasma. METHODS: A total of 1060 primer pairs were designed to determine fetal aneuploidy status, fetal sex, and fetal fraction. Each library was prepared from cfDNA by coamplifying all 1060 target pairs together in a single reaction well. Products were measured using massively parallel sequencing and deviations from expected paralog ratios were determined based on the read depth from each paralog. RESULTS: We evaluated this assay in a blinded set of 480 cfDNA samples with fetal aneuploidy status determined by the MaterniT21(r) PLUS assay. Samples were sequenced (mean = 2.3 million reads) with 432 samples returning a result. Using the MaterniT21 PLUS assay for paired plasma aliquots from the same individuals as a reference, all 385 euploid samples, all 31 T21 samples, and 14 of 16 T18 samples were detected with no false positive results observed. CONCLUSIONS: This study introduces a novel NIPT aneuploidy detection approach using targeted sequencing of paralog motifs and establishes proof-of-concept for a potentially low-cost, highly scalable method for the identification of selected fetal aneuploidies with performance and nonreportable rate similar to other published methods. PMID- 27694393 TI - Stable-Isotope Dilution HPLC-Electrospray Ionization Tandem Mass Spectrometry Method for Quantifying Hydroxyurea in Dried Blood Samples. AB - BACKGROUND: Sickle cell anemia (SCA) is a life-threatening blood disorder characterized by the presence of sickle-shaped erythrocytes. Hydroxyurea is currently the only US Food and Drug Administration-approved treatment and there is a need for a convenient method to monitor compliance and hydroxyurea concentrations, especially in pediatric SCA patients. METHODS: We describe a novel approach to the determination of hydroxyurea concentrations in dried whole blood collected on DMPK-C cards or volumetric absorptive microsampling (VAMS) devices. Hydroxyurea was quantified by electrospray ionization LC-MS/MS using [13C15N2]hydroxyurea as the internal standard. Calibrators were prepared in whole blood applied to DMPK-C cards or VAMS devices. RESULTS: Calibration curves for blood hydroxyurea measured from DMPK-C cards and VAMS devices were linear over the range 0.5-60 MUg/mL. Interassay and intraassay CVs were <15% for blood collected by both methods, and the limit of detection was 5 ng/mL. Whole blood hydroxyurea was stable for up to 60 days on DMPK-C cards and VAMS devices when frozen at -20 degrees C or -80 degrees C. Whole blood hydroxyurea concentrations in samples collected on DMPK-C cards or VAMS devices from SCA patients were in close agreement. CONCLUSIONS: This tandem mass spectrometry method permits measurement of hydroxyurea concentrations in small volumes of dried blood applied to either DMPK-C cards or VAMS devices with comparable performance. This method for measuring hydroxyurea from dried blood permits the evaluation of therapeutic drug monitoring, individual pharmacokinetics, and medication adherence using heel/finger-prick samples from pediatric patients with SCA treated with hydroxyurea. PMID- 27694392 TI - Short-term Variability of Vitamin D-Related Biomarkers. AB - BACKGROUND: Quantifying the variability of biomarkers is important, as high within-person variability can lead to misclassification of individuals. Short term variability of important markers of vitamin D metabolism is relatively unknown. METHODS: A repeatability study was conducted in 160 Atherosclerosis Risk in Communities study participants (60% female, 28% black, mean age 76 years). Fasting serum was drawn at 2 time points, a median of 6 (range 3-13) weeks apart. Vitamin D binding protein (VDBP) and 25-hydroxyvitamin D [25(OH)D] were measured by LC-MS, fibroblast growth factor (FGF23) and parathyroid hormone (PTH) by enzyme-linked immunoassay, and calcium and phosphorus by Roche Cobas 6000. Free and bioavailable 25(OH)D were calculated. We calculated the within-person CV (CVW), intraclass correlation coefficient (ICC), Spearman rank correlation coefficient (r), and percent reclassified. RESULTS: The CVW was lowest for calcium (2.0%), albumin (3.6%), 25(OH)D (6.9%), VDBP (7.0%) and phosphorus (7.6%); intermediate for free 25(OH)D (9.0%) and bioavailable 25(OH)D (9.9%); and highest for PTH (16.7%) and FGF23 (17.8%). Reclassification was highest for PTH, VDBP, and phosphorus (all 7.5%). The ICC and r were highest (>=0.80) for 25(OH)D, free 25(OH)D, bioavailable 25(OH)D and PTH, but somewhat lower (approximately 0.60-0.75) for the other biomarkers. CONCLUSIONS: Six-week short-term variability, as assessed by CVW, was quite low for VDBP, calcium and phosphorus, but fairly high for FGF23 and PTH. As such, multiple measurements of FGF23 and PTH may be needed to minimize misclassification. These results provide insight into the extent of potential misclassification of vitamin D markers in research and clinical settings. PMID- 27694394 TI - Focus on Ecophysiology.

AB - BACKGROUND AND OBJECTIVE: The American Academy of Pediatrics recommends that preterm infants complete a predischarge 'car seat challenge' observation for cardiorespiratory compromise while in a car seat. This static challenge does not consider the more upright position in a car or the vibration of the seat when the car is moving. This pilot study was designed to assess the cardiorespiratory effects of vibration, mimicking the effect of being in a moving car, on preterm and term infants. METHODS: A simulator was designed to reproduce vertical vibration similar to that in a rear-facing car seat at 30 mph. 19 healthy newborn term and 21 preterm infants, ready for hospital discharge, underwent cardiorespiratory measurements while lying flat in a cot (baseline), static in the seat (30 degrees ), simulator (40 degrees ) and during motion (vibration 40 degrees ). RESULTS: Median test age was 13 days (range 1-65 days) and median weight was 2.5 kg (IQR: 2.1-3.1 kg).Compared with baseline observations, only the total number of desaturations was significantly increased when infants were placed at 30 degrees (p=0.03). At 40 degrees , or with vibration, respiratory and heart rates increased and oxygen saturation decreased significantly. Profound desaturations <85% significantly increased during motion, regardless of gestational age. CONCLUSIONS: This is the first study to assess the effect of motion on infants seated in a car safety seat. Term and preterm infants showed significant signs of potentially adverse cardiorespiratory effects in the upright position at 40 degrees , particularly with simulated motion, not identified in the standard challenge. A larger study is required to investigate the significance of these results. PMID- 27694400 TI - An Epidemiological Study of Burglary Offenders: Trends and Predictors of Self Reported Arrests for Burglary in the United States, 2002-2013. AB - Burglary is serious property crime with a relatively high incidence and has been shown to be variously associated with other forms of criminal behavior. Unfortunately, an epidemiological understanding of burglary and its correlates is largely missing from the literature. Using public-use data collected between 2002 and 2013 as part of the National Survey on Drug Use and Health (NSDUH), the current study compared those who self-reported burglary arrest in the prior 12 months with and without criminal history. The unadjusted prevalence estimates of self-reported burglary arrest were statistically different for those with a prior arrest history (4.7%) compared with those without an arrest history (0.02%) which is a 235-fold difference. Those with an arrest history were more likely to report lower educational attainment, to have lower income, to have moved more than 3 times in the past 5 years, and to use alcohol, tobacco, illicit drugs, and engage in binge drinking. Moreover, those with prior arrest histories were younger and more likely to be male. There is considerable heterogeneity among burglars with criminal history indicating substantially greater behavioral risk. PMID- 27694401 TI - Analysis of the logic and framing of a tobacco industry campaign opposing standardised packaging legislation in New Zealand. AB - BACKGROUND: The tobacco industry routinely opposes tobacco control policies, often using a standard repertoire of arguments. Following proposals to introduce standardised packaging in New Zealand (NZ), British American Tobacco New Zealand (BATNZ) launched the 'Agree-Disagree' mass media campaign, which coincided with the NZ government's standardised packaging consultations. This study examined the logic of the arguments presented and rhetorical strategies employed in the campaign. METHODS: We analysed each advertisement to identify key messages, arguments and rhetorical devices, then examined the arguments' structure and assessed their logical soundness and validity. RESULTS: All advertisements attempted to frame BATNZ as reasonable, and each contained flawed arguments that were either unsound or based on logical fallacies. Flawed arguments included misrepresenting the intent of the proposed legislation (straw man), claiming standardised packaging would harm all NZ brands (false dilemma), warning NZ not to adopt standardised packaging because of its Australian origins (an unsound argument) or using vague premises as a basis for claiming negative outcomes (equivocation). CONCLUSIONS: BATNZ's Agree-Disagree campaign relied on unsound arguments, logical fallacies and rhetorical devices. Given the industry's frequent recourse to these tactics, we propose strategies based on our study findings that can be used to assist the tobacco control community to counter industry opposition to standardised packaging. Greater recognition of logical fallacies and rhetorical devices employed by the tobacco industry will help maintain focus on the health benefits proposed policies will deliver. PMID- 27694402 TI - The effect of ankle posture on the load pathway through the hindfoot. AB - The foot-ankle complex is frequently injured in a wide array of debilitating events such as car crashes. Numerical models and experimental tests have been used to assess injury risk, but most do not account for the variations in ankle posture that frequently occur during these events. In this study, the positions of the bones of the foot-ankle complex (particularly, the hindfoot) were quantified over a range of postures. Computed tomography scans were taken of a male cadaveric leg under axial loading with the ankle in five postures in which fractures are commonly reported. The difference in the location of the talus and calcaneus between the neutral and each repositioned posture was quantified, and substantial rotations and displacements were observed for all postures tested (talus: 3 degrees -21.5 degrees , 1.5-10.5 mm; calcaneus: 10 degrees -20 degrees , 1.5-24.5 mm). Strains were also recorded at six locations on bones of the ankle during testing and were found to be highest in the calcaneus during inversion external rotation and highest in the talus during eversion-external rotation. Postural changes likely affect the load pathway of the foot-ankle complex, potentially altering the stress and strain fields from that of the neutral case and changing the location of fracture. This highlights the need for injury predicting studies examining the effect of these positional changes and to develop revised injury criteria accounting for the most vulnerable conditions. PMID- 27694404 TI - Type D personality and periodontal disease in university students: A prospective cohort study. AB - The purpose of this prospective cohort study was to investigate whether Type D personality was related to periodontal disease in Japanese university students. Among students ( n = 600) who were interested in receiving oral health examinations, logistic regression analysis showed that the risk of developing periodontal disease during a 3-year period was associated with body mass index ? 25 (odds ratio: 2.543; 95% confidence interval: 1.297-4.989; p = 0.007) and Type D personality (odds ratio: 1.473; 95% confidence interval: 1.027-2.111; p = 0.035). In this short-term prospective cohort study, a significant association between periodontal disease and Type D personality was observed in Japanese university students. PMID- 27694403 TI - Analysis on the Complete Mitochondrial Genome of Andraca theae (Lepidoptera: Bombycoidea). AB - The bombycid moth, Andraca theae (Matsumura) (Lepidoptera: Bombycoidea) is an important pest of tea in southeastern China. In the present study, the mitochondrial genome (mitogenome) of A. theae was amplified by polymerase chain reaction and sequenced. The complete mitogenome of A. theae, encoding 37 genes, was 15,737 bp in length (Genbank no. KX365419), and consisted of 13 protein coding genes (PCGs), 22 tRNA genes, 2 ribosomal RNA genes and an adenine (A) + thymine (T)-rich region (AT-rich region). The gene order of A. theae mitogenome was typical for Lepidoptera mitogenomes. Except for cox1, which started with CGA, all other 12 PCGs started with ATN. Eleven of the 13 PCGs ended with TAA, expect for cox1 and cox2, which ended with a single T. The maximum likelihood method and the Bayesian method were used to analyze the phylogenetic relationship among 22 representative bombycoid species with a matrix consisting of the 13 PCGs of the mitogenomes of the 22 species. The topological structures of the two phylogenetic trees we constructed were almost identical, with the results indicating that the bombycid species, including A. theae, clustered into a single clade with a bootstrap value of 58% and a posterior probability of 0.98. The phylogenetic relationship among the Bombycoidea species analyzed was Lasiocampidae + (Bombycidae + (Saturniidae + Sphingidae)) which was supported by a high bootstrap value of 100% and a posterior probability of 1.00. PMID- 27694405 TI - European Colonization, Not Polynesian Arrival, Impacted Population Size and Genetic Diversity in the Critically Endangered New Zealand Kakapo. AB - Island endemic species are often vulnerable to decline and extinction following human settlement, and the genetic study of historical museum specimens can be useful in understanding these processes. The kakapo (Strigops habroptilus) is a critically endangered New Zealand parrot that was formerly widespread and abundant. It is well established that both Polynesian and European colonization of New Zealand impacted the native avifauna, but the timeframe and severity of impacts have differed depending on species. Here, we investigated the relative importance of the 2 waves of human settlement on kakapo decline, using microsatellites and mitochondrial DNA (mtDNA) to characterize recent kakapo genetic and demographic history. We analyzed samples from 49 contemporary individuals and 54 museum specimens dating from 1884 to 1985. Genetic diversity decreased significantly between historical and contemporary kakapo, with a decline in mean number of microsatellite alleles from 6.15 to 3.08 and in number of mtDNA haplotypes from 17 to 3. Modeling of demographic history indicated a recent population bottleneck linked to the period of European colonization (approximately 5 generations ago) but did not support a major decline linked to Polynesian settlement. Effective population size estimates were also larger for historical than contemporary kakapo. Our findings inform contemporary kakapo management by indicating the timeframe and possible cause of the bottleneck, which has implications for the management of extant genetic diversity. We demonstrate the broader utility of a historical perspective in understanding causes of decline and managing extinction risk in contemporary endangered species.

PMID- 27694423 TI - Posttransplant Lymphoproliferative Disorders in Neuronal Xenotransplanted Macaques. AB - Posttransplant lymphoproliferative disorders (PTLDs) are a heterogeneous group of lymphoid proliferations that occur in the setting of depressed T-cell function due to immunosuppressive therapy used following solid organ transplantation, hematopoietic stem cell transplantation, and also xenotransplantation. In the present study, 28 immunosuppressed parkinsonian Macaca fascicularis were intracerebrally injected with wild-type or CTLA4-Ig transgenic porcine xenografts to identify a suitable strategy to enable long-term cell survival, maturation, and differentiation. Nine of 28 (32%) immunosuppressed primates developed masses compatible with PTLD, located mainly in the gastrointestinal tract and/or nasal cavity. The masses were classified as monomorphic PTLD according to the World Health Organization classification. Immunohistochemistry and polymerase chain reaction (PCR) analyses revealed that the PTLDs were associated with macaca lymphocryptovirus as confirmed by double-labeling immunohistochemistry for CD20 and Epstein-Barr nuclear antigen 2 (EBNA-2), where the viral protein was located within the CD20+ neoplastic B cells. In sera from 3 distinct phases of the experimental life of the primates, testing by quantitative PCR revealed a progression of the viral load that paralleled the PTLD progression and no evidence of zoonotic transmission of porcine lymphotropic herpesvirus through xenoneuronal grafts. These data suggest that monitoring the variation of macaca lymphocryptovirus DNA in primates could be used as a possible early diagnostic tool for PTLD progression, allowing preemptive treatment such as immunosuppression therapy reduction. PMID- 27694424 TI - Ocular Lesions in Red-Tailed Hawks ( Buteo jamaicensis) With Naturally Acquired West Nile Disease. AB - Ocular lesions are common in red-tailed hawks with West Nile (WN) disease. These lesions consist of pectenitis, choroidal or retinal inflammation, or retinal necrosis, but detailed investigation of the ocular lesions is lacking. Postmortem examination of the eyes of 16 red-tailed hawks with naturally acquired WN disease and 3 red-tailed hawks without WN disease was performed using histopathology, immunohistochemistry for West Nile virus (WNV) antigen, glial fibrillary acid protein, cleaved caspase-3, and the terminal deoxynucleotidyl transferase mediated dUTP nick-end labeling method. Retinal lesions were classified as type I or type II lesions. Type I lesions were characterized by lymphoplasmacytic infiltrates in the subjacent choroid with degeneration limited to the outer retina (type Ia lesion) or with degeneration and necrosis of the outer retina or outer and inner retina (type Ib lesion) while retinal collapse, atrophy, and scarring were hallmarks of type II lesions. Type II retinal lesions were associated with a more pronounced choroiditis. Although not statistically significant, WNV antigen tended to be present in larger quantity in type Ib lesions. Type I lesions are considered acute while type II lesions are chronic. The development of retinal lesions was associated with the presence of an inflammatory infiltrate in the choroid. A breakdown of the blood-retina barrier is suspected to be the main route of infection of the retina. Within the retina, virus appeared to spread via both neuronal and Muller cell processes. PMID- 27694425 TI - Left Ventricular Apical Aneurysm in a Cat With Primary Cardiomyopathy. AB - A 13-year-old female Persian cat died suddenly after severe respiratory distress. At necropsy, the changes were compatible with congestive heart failure. The heart was enlarged with a flabby and puckered sac-like aneurysm at the apex of the left ventricle. The apical zone showed a thin muscular wall arising from the free wall of the left ventricle connected to a bulged saccular area through a wide communication. Microscopically, the wall of the aneurysm was composed of fibrous connective tissue with neovascularization and sparse atrophied myocardial cells at the margins. A few isolated cardiomyocytes in the lesion stained positively for desmin, and the inner lining of the aneurysm had immunoreactivity to von Willebrand factor and CD31. Mature fibrous connective tissue was interspersed with degenerated and disorganized cardiomyocytes elsewhere in the myocardium, and many small myocardial arteries were tortuous and thickened. In this case of sudden death, the diagnosis was primary cardiomyopathy, with formation of a left ventricular apical aneurysm within an area of marked myocardial fibrosis and cardiomyocyte atrophy. PMID- 27694426 TI - Pathologic Findings and Viral Antigen Distribution During Natural Infection of Ring-Necked Pheasants With H5N2 Highly Pathogenic Avian Influenza Virus A. AB - Highly pathogenic avian influenza (HPAI) is a major viral disease of poultry characterized by acute onset, systemic infection, and rapid death. In January 2015, H5N2 HPAI was identified by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) and gene sequencing as the cause of rapid death in 40 of 390 ring-necked pheasants (approximately 10% mortality), raised in a game bird farm in Washington State. We report clinicopathologic findings and viral antigen distribution in pheasants that died during the outbreak. Affected birds were depressed with reluctance to move, ruffled feathers, and drooping heads. Congestion of the cerebellar meningeal blood vessels was the only consistent gross pathologic finding. Meningoencephalitis with vasculitis and necrosis in the spleen and heart were the major microscopic lesions in the birds. Viral antigen was consistently detected in the brain, heart, and ovary with variable presence in other organs. PMID- 27694427 TI - Barriers to Medical Error Reporting for Physicians and Nurses. AB - The purpose of the study was to determine what barriers to error reporting exist for physicians and nurses. The study, of descriptive qualitative design, was conducted with physicians and nurses working at a training and research hospital. In-depth interviews were held with eight physicians and 15 nurses, a total of 23 participants. Physicians and nurses do not choose to report medical errors that they experience or witness. When barriers to error reporting were examined, it was seen that there were four main themes involved: fear, the attitude of administration, barriers related to the system, and the employees' perceptions of error. It is important in terms of preventing medical errors to identify the barriers that keep physicians and nurses from reporting errors. PMID- 27694428 TI - Cardiorespiratory fitness testing and cardiovascular disease risk in male steelworkers. AB - BACKGROUND: The workplace has been advocated as a setting to perform cardiovascular disease (CVD) risk assessments. These risk assessments usually focus on traditional risk factors rather than cardiorespiratory fitness (CRF) despite established associations between CRF and CVD. The lack of guidance on interpreting health-related CRF values has been suggested as a barrier to utilizing CRF in practice. AIMS: To assess the merits of CRF testing in the workplace and explore whether a CRF value identified male individuals above the recommended threshold for further clinical investigation. METHODS: Cross sectional analysis of male steelworkers from Carmarthenshire, South Wales, UK who completed a workplace-based CVD risk assessment with an added CRF protocol based on heart rate responses (Chester Step Test). Receiver operating characteristic (ROC) analysis was undertaken to explore the possibility of a CRF value to identify individuals at an increased 10-year risk of CVD (QRISK2 >= 10%). RESULTS: There were 81 participants. ROC analysis revealed that a CRF level of 34.5ml/kg/min identified those individuals above the >=10% QRISK2 threshold with the best sensitivity (0.800) and specificity (0.687) to discriminate against true and false-positive rates. Further analysis revealed that individuals with either 'Average' or 'Below Average' CRF would be five times more likely to have a 10 year CVD risk above the >=10% QRISK2 threshold than individuals with an 'Excellent' or 'Good' level of fitness [OR 5.10 (95% CI 1.60-16.3)]. CONCLUSIONS: This study suggests CRF assessments are a useful addition to a workplace CVD assessment and could identify male individuals at increased predicted risk of the condition. PMID- 27694429 TI - Determination of Nickel and Manganese Contaminants in Pharmaceutical Iron Supplements Using Energy Dispersive X-ray Fluorescence. AB - In this study, we investigate the capability of energy dispersive X-ray fluorescence (EDXF) spectrometry in a triaxial geometry apparatus as a fast and nondestructive determination method of both dominant and contaminant elements in pharmaceutical iron supplements. The following iron supplements brands with their respective active ingredients were analyzed: Neutrofer folico (iron gylcinate), Anemifer (iron(II) sulfate monohydrate), Noripurum (iron(III)-hydroxide polymaltose complex), Sulferbel (iron(II) sulfate monohydrate), and Combiron Folico (carbonyl iron). Although we observe a good agreement between the iron content obtained by the present method and that indicated in the supplement's prescribed dose, we observe contamination by manganese and nickel of up to 180 MUg and 36 MUg, respectively. These contents correspond to 7.2% and 14.4% of the permitted daily exposure of manganese and nickel, respectively, for an average adult individual as determined by the European Medicine Agency (EMEA). The method was successfully validated against the concentrations of several certified reference materials of biological light matrices with similar concentrations of contaminants. Moreover, we also validated our method by comparing the concentrations with those obtained with the inductively coupled plasma-atomic emission technique. PMID- 27694430 TI - Background Subtraction of Raman Spectra Based on Iterative Polynomial Smoothing. AB - In this paper, a novel background subtraction algorithm is presented that can automatically recover Raman signal. This algorithm is based on an iterative polynomial smoothing method that highly reduces the need for experience and a priori knowledge. First, a polynomial filter is applied to smooth the input spectrum (the input spectrum is just an original spectrum at the first iteration). The output curve of the filter divides the original spectrum into two parts, top and bottom. Second, a proportion is calculated between the lowest point of the signal in the bottom part and the highest point of the signal in the top part. The proportion is a key index that decides whether to go into a new iteration. If a new iteration is needed, the minimum value between the output curve and the original spectrum forms a new curve that goes into the same filter in the first step and continues as another iteration until no more iteration is needed to finally get the background of the original spectrum. Results from the simulation experiments not only show that the iterative polynomial smoothing algorithm achieves good performance, processing time, cost, and accuracy of recovery, but also prove that the algorithm adapts to different background types and a large signal-to-noise ratio range. Furthermore, real measured Raman spectra of organic mixtures and non-organic samples are used to demonstrate the application of the algorithm. PMID- 27694435 TI - Role of lipid phosphate phosphatase 3 in human aortic endothelial cell function. AB - AIMS: Lipid phosphate phosphatase 3; type 2 phosphatidic acid phosphatase beta (LPP3; PPAP2B) is a transmembrane protein dephosphorylating and thereby terminating signalling of lipid substrates including lysophosphatidic acid (LPA) and sphingosine-1-phosphate (S1P). Human LPP3 possesses a cell adhesion motif that allows interaction with integrins. A polymorphism (rs17114036) in PPAP2B is associated with coronary artery disease, which prompted us to investigate the possible role of LPP3 in human endothelial dysfunction, a condition promoting atherosclerosis. METHODS AND RESULTS: To study the role of LPP3 in endothelial cells we used human primary aortic endothelial cells (HAECs) in which LPP3 was silenced or overexpressed using either wild type or mutated cDNA constructs. LPP3 silencing in HAECs enhanced secretion of inflammatory cytokines, leucocyte adhesion, cell survival, and migration and impaired angiogenesis, whereas wild type LPP3 overexpression reversed these effects and induced apoptosis. We also demonstrated that LPP3 expression was negatively correlated with vascular endothelial growth factor expression. Mutations in either the catalytic or the arginine-glycine-aspartate (RGD) domains impaired endothelial cell function and pharmacological inhibition of S1P or LPA restored it. LPA was not secreted in HAECs under silencing or overexpressing LPP3. However, the intra- and extra cellular levels of S1P tended to be correlated with LPP3 expression, indicating that S1P is probably degraded by LPP3. CONCLUSIONS: We demonstrated that LPP3 is a negative regulator of inflammatory cytokines, leucocyte adhesion, cell survival, and migration in HAECs, suggesting a protective role of LPP3 against endothelial dysfunction in humans. Both the catalytic and the RGD functional domains were involved and S1P, but not LPA, might be the endogenous substrate of LPP3. PMID- 27694436 TI - Effectiveness of Two Community Health Worker Models of Tobacco Dependence Treatment Among Community Residents of Ohio Appalachia. AB - Introduction: Community health workers (CHW) may be effective in the delivery of tobacco dependence treatment with underserved groups. This study evaluated two evidence-based CHW models of treatment. It was hypothesized that smokers assigned to a CHW face-to-face condition would have higher abstinence at 12-month posttreatment than smokers enrolled in CHW referral to a state-sponsored quitline condition. Intrapersonal and treatment-related factors associated with abstinence at 12 months were determined. Methods: A group-randomized trial was conducted with residents of 12 Ohio Appalachian counties with counties (n = 6) randomized to either a CHW face-to-face (F2F) or CHW quitline (QL) condition. Both conditions included behavioral counseling and free nicotine replacement therapy for 8 weeks. Follow-up data were collected at 3-, 6-, and 12-month posttreatment. Biochemically validated abstinence at 12 months served as the primary outcome. Results: Seven hundred and seven participants were enrolled (n = 353 CHWF2F; n = 354 CHWQL). Baseline sample characteristics did not differ by condition. Using an intent-to-treat analysis (85.4% retention at 12 months), 13.3% of CHWF2F participants were abstinent at 12 months, compared to 10.7% of CHWQL members (OR = 1.28; 95% confidence interval [CI] = 0.810, 2.014; p = .292). No differences in abstinence were noted at 3 or 6 months by condition. Age, marital status, and baseline levels of cigarette consumption, depressive symptoms, and self-efficacy for quitting in positive settings were associated with abstinence, as was counseling dose during treatment. Conclusions: This research adds to the body of science evaluating the effectiveness of CHW models of tobacco dependence treatment. Both approaches may offer promise in low-resource settings and underserved regions. Implications: This 12-county community-based group randomized trial in Ohio Appalachia adds to the body of science evaluating the effectiveness of CHW models of tobacco dependence treatment. Both CHW approaches may offer promise in low-resource settings and underserved regions. These findings are useful to national, state, and local tobacco control agencies, as they expand delivery of preventive health care services postadoption of the Affordable Care Act in the United States. PMID- 27694437 TI - One-Year Smoking Trajectories Among Established Adult Smokers With Low Baseline Motivation to Quit. AB - Introduction: The majority of smokers do not intend to quit in the near term, making unmotivated smokers a key group to target in public health efforts. Although it is often assumed that continuing smokers will have stable rates of smoking over time, limited research has addressed this issue, particularly among smokers not seeking treatment. In the current study, the aims were to (1) characterize the trajectory of naturalistic smoking among unmotivated smokers and (2) examine relationships between naturalistic smoking trajectories and other smoking-related variables. Methods: The study sample comprised 579 control-group (ie, untreated) smokers within a parent clinical trial, who completed a total of nine assessments over 1 year. Results: Trajectory modeling identified four smoking trajectory groups: stable (72%), shallow decreasers (20%), steep decreasers (5%), and increasers (3%). Membership in the decreasing groups was associated with higher motivation to quit, greater history of quit attempts, and higher cigarettes per day. Females were more likely to be in the increasing versus stable group. Conclusions: Findings provide needed information on stability and change in cigarette consumption over the course of 1 year among an untreated sample of smokers and identified baseline sociodemographic and smoking related predictors of smoking trajectory group. Refining understanding of these groups is critical in updating population-based tobacco policy modeling efforts and informing cessation induction efforts that capitalize on naturalistic changes in smoking rate over time. Implications: In the current study, we found that approximately 25% of smokers who endorsed low quit motivation at baseline reduced their cigarette consumption over the course of a year, while 3% increased their cigarette consumption and the majority of smokers (72%) maintained a stable pattern. Refining understanding of smoking trajectories is critical in updating population-based tobacco policy modeling efforts and informing cessation induction efforts that capitalize on naturalistic changes in smoking rate over time. PMID- 27694438 TI - Ten-Year Course of Cosmic Transcendence in Older Adults in the Netherlands. AB - Objectives Gerotranscendence is defined as a transition from a materialistic and rationalistic perspective to a more cosmic and transcendent view of life accompanying the aging process. Would gerotranscendence levels still increase in later life? The current prospective study investigates 10-year trajectories of cosmic transcendence (a core dimension of gerotranscendence). Methods Four interview cycles of the Longitudinal Aging Study Amsterdam with 3-year intervals from 1995 to 2006 provide data on cosmic transcendence, demographics (ages 57 85), religiousness, health, sense of mastery, and humor coping. Data are available for 2,257 respondents and 1,533 respondents in multivariate models. Results Latent Class Growth Analysis shows three course trajectories of cosmic transcendence: stable high, intermediate with a decrease, and stable low. Higher levels are predicted by age, importance of prayer, Roman Catholic affiliation, a low sense of mastery, higher cognitive ability, and humor coping. Similar results were obtained for the respondents who died during the study ( N = 378). Discussion Although levels of cosmic transcendence do not show much change during 10 years of follow-up, the oldest respondents nonetheless attain the highest cosmic transcendence levels. An inclination toward relativism and contemplation may facilitate cosmic transcendence. However, lower cognitive ability probably impairs the development toward cosmic transcendence.

AB - O6-Methyl-2'-deoxyguanosine (O6-MeG) is a ubiquitous DNA lesion, formed not only by xenobiotic carcinogens but also by the endogenous methylating agent S adenosylmethionine. It can introduce mutations during DNA replication, with different DNA polymerases displaying different ratios of correct or incorrect incorporation opposite this nucleoside. Of the "translesion" Y-family human DNA polymerases (hpols), hpol eta is most efficient in incorporating equal numbers of correct and incorrect C and T bases. However, the mechanistic basis for this specific yet indiscriminate activity is not known. To explore this question, we report biochemical and structural analysis of the catalytic core of hpol eta. Activity assays showed the truncated form displayed similar misincorporation properties as the full-length enzyme, incorporating C and T equally and extending from both. X-ray crystal structures of both dC and dT paired with O6-MeG were solved in both insertion and extension modes. The structures revealed a Watson Crick-like pairing between O6-MeG and 2"-deoxythymidine-5"-[(alpha, beta) imido]triphosphate (approximating dT) at both the insertion and extension stages with formation of two H-bonds. Conversely, both the structures with O6- MeG opposite dCTP and dC display sheared configuration of base pairs but to different degrees, with formation of two bifurcated H-bonds and two single H-bonds in the structures trapped in the insertion and extension states, respectively. The structural data are consistent with the observed tendency of hpol eta to insert both dC and dT opposite the O6-MeG lesion with similar efficiencies. Comparison of the hpol eta active site configurations with either O6-MeG:dC or O6-MeG:dT bound compared with the corresponding situations in structures of complexes of Sulfolobus solfataricus Dpo4, a bypass pol that favors C relative to T by a factor of ~4, helps rationalize the more error-prone synthesis opposite the lesion by hpol eta. PMID- 27694441 TI - Electron Accepting Units of the Diheme Cytochrome c TsdA, a Bifunctional Thiosulfate Dehydrogenase/Tetrathionate Reductase. AB - The enzymes of the thiosulfate dehydrogenase (TsdA) family are wide-spread diheme c-type cytochromes. Here, redox carriers were studied mediating the flow of electrons arising from thiosulfate oxidation into respiratory or photosynthetic electron chains. In a number of organisms, including Thiomonas intermedia and Sideroxydans lithotrophicus, the tsdA gene is immediately preceded by tsdB encoding for another diheme cytochrome. Spectrophotometric experiments in combination with enzymatic assays in solution showed that TsdB acts as an effective electron acceptor of TsdA in vitro when TsdA and TsdB originate from the same source organism. Although TsdA covers a range from -300 to +150 mV, TsdB is redox active between -100 and +300 mV, thus enabling electron transfer between these hemoproteins. The three-dimensional structure of the TsdB-TsdA fusion protein from the purple sulfur bacterium Marichromatium purpuratum was solved by X-ray crystallography to 2.75 A resolution providing insights into internal electron transfer. In the oxidized state, this tetraheme cytochrome c contains three hemes with axial His/Met ligation, whereas heme 3 exhibits the His/Cys coordination typical for TsdA active sites. Interestingly, thiosulfate is covalently bound to Cys330 on heme 3. In several bacteria, including Allochromatium vinosum, TsdB is not present, precluding a general and essential role for electron flow. Both AvTsdA and the MpTsdBA fusion react efficiently in vitro with high potential iron-sulfur protein from A. vinosum (Em +350 mV). High potential iron-sulfur protein not only acts as direct electron donor to the reaction center in anoxygenic phototrophs but can also be involved in aerobic respiratory chains. PMID- 27694440 TI - Depletion of the Human Ion Channel TRPM2 in Neuroblastoma Demonstrates Its Key Role in Cell Survival through Modulation of Mitochondrial Reactive Oxygen Species and Bioenergetics. AB - Transient receptor potential melastatin 2 (TRPM2) ion channel has an essential function in modulating cell survival following oxidant injury and is highly expressed in many cancers including neuroblastoma. Here, in xenografts generated from neuroblastoma cells in which TRPM2 was depleted with CRISPR/Cas9 technology and in in vitro experiments, tumor growth was significantly inhibited and doxorubicin sensitivity increased. The hypoxia-inducible transcription factor 1/2alpha (HIF-1/2alpha) signaling cascade including proteins involved in oxidant stress, glycolysis, and mitochondrial function was suppressed by TRPM2 depletion. TRPM2-depleted SH-SY5Y neuroblastoma cells demonstrated reduced oxygen consumption and ATP production after doxorubicin, confirming impaired cellular bioenergetics. In cells in which TRPM2 was depleted, mitochondrial superoxide production was significantly increased, particularly following doxorubicin. Ectopic expression of superoxide dismutase 2 (SOD2) reduced ROS and preserved viability of TRPM2-depleted cells, however, failed to restore ATP levels. Mitochondrial reactive oxygen species (ROS) were also significantly increased in cells in which TRPM2 function was inhibited by TRPM2-S, and pretreatment of these cells with the antioxidant MitoTEMPO significantly reduced ROS levels in response to doxorubicin and protected cell viability. Expression of the TRPM2 pore mutant E960D, in which calcium entry through TRPM2 is abolished, also resulted in significantly increased mitochondrial ROS following doxorubicin treatment, showing the critical role of TRPM2-mediated calcium entry. These findings demonstrate the important function of TRPM2 in modulation of cell survival through mitochondrial ROS, and the potential of targeted inhibition of TRPM2 as a therapeutic approach to reduce cellular bioenergetics, tumor growth, and enhance susceptibility to chemotherapeutic agents. PMID- 27694442 TI - Cell-specific Kaiso (ZBTB33) Regulation of Cell Cycle through Cyclin D1 and Cyclin E1. AB - The correlation between aberrant DNA methylation with cancer promotion and progression has prompted an interest in discerning the associated regulatory mechanisms. Kaiso (ZBTB33) is a specialized transcription factor that selectively recognizes methylated CpG-containing sites as well as a sequence-specific DNA target. Increasing reports link ZBTB33 overexpression and transcriptional activities with metastatic potential and poor prognosis in cancer, although there is little mechanistic insight into how cells harness ZBTB33 transcriptional capabilities to promote and progress disease. Here we report mechanistic details for how ZBTB33 mediates cell-specific cell cycle regulation. By utilizing ZBTB33 depletion and overexpression studies, it was determined that in HeLa cells ZBTB33 directly occupies the promoters of cyclin D1 and cyclin E1, inducing proliferation by promoting retinoblastoma phosphorylation and allowing for E2F transcriptional activity that accelerates G1- to S-phase transition. Conversely, in HEK293 cells ZBTB33 indirectly regulates cyclin E abundance resulting in reduced retinoblastoma phosphorylation, decreased E2F activity, and decelerated G1 transition. Thus, we identified a novel mechanism by which ZBTB33 mediates the cyclin D1/cyclin E1/RB1/E2F pathway, controlling passage through the G1 restriction point and accelerating cancer cell proliferation. PMID- 27694443 TI - Balancing Selectivity and Efficacy of Bispecific Epidermal Growth Factor Receptor (EGFR) * c-MET Antibodies and Antibody-Drug Conjugates. AB - Bispecific antibodies (bsAbs) and antibody-drug conjugates (ADCs) have already demonstrated benefits for the treatment of cancer in several clinical studies, showing improved drug selectivity and efficacy. In particular, simultaneous targeting of prominent cancer antigens, such as EGF receptor (EGFR) and c-MET, by bsAbs has raised increasing interest for potentially circumventing receptor cross talk and c-MET-mediated acquired resistance during anti-EGFR monotherapy. In this study, we combined the selectivity of EGFR * c-MET bsAbs with the potency of cytotoxic agents via bispecific antibody-toxin conjugation. Affinity-attenuated bispecific EGFR * c-MET antibody-drug conjugates demonstrated high in vitro selectivity toward tumor cells overexpressing both antigens and potent anti-tumor efficacy. Due to basal EGFR expression in the skin, ADCs targeting EGFR in general warrant early safety assessments. Reduction in EGFR affinity led to decreased toxicity in keratinocytes. Thus, the combination of bsAb affinity engineering with the concept of toxin conjugation may be a viable route to improve the safety profile of ADCs targeting ubiquitously expressed antigens. PMID- 27694444 TI - Structural Dynamics of the Vimentin Coiled-coil Contact Regions Involved in Filament Assembly as Revealed by Hydrogen-Deuterium Exchange. AB - Intermediate filaments (IF) are major constituents of the cytoskeleton of metazoan cells. They are not only responsible for the mechanical properties but also for various physiological activities in different cells and tissues. The building blocks of IFs are extended coiled-coil-forming proteins exhibiting a characteristic central alpha-helical domain ("rod"). The fundamental principles of the filament assembly mechanism and the network formation have been widely elucidated for the cytoplasmic IF protein vimentin. Also, a comprehensive structural model for the tetrameric complex of vimentin has been obtained by X ray crystallography in combination with various biochemical and biophysical techniques. To extend these static data and to investigate the dynamic properties of the full-length proteins in solution during the various assembly steps, we analyzed the patterns of hydrogen-deuterium exchange in vimentin and in four variants carrying point mutations in the IF consensus motifs present at either end of the alpha-helical rod that cause an assembly arrest at the unit-length filament (ULF) stage. The results yielded unique insights into the structural properties of subdomains within the full-length vimentin, in particular in regions of contact in alpha-helical and linker segments that stabilize different oligomeric forms such as tetramers, ULFs, and mature filaments. Moreover, hydrogen-deuterium exchange analysis of the point-mutated variants directly demonstrated the active role of the IF consensus motifs in the oligomerization mechanism of tetramers during ULF formation. Ultimately, using molecular dynamics simulation procedures, we provide a structural model for the subdomain-mediated tetramer/tetramer interaction via "cross-coiling" as the first step of the assembly process. PMID- 27694445 TI - StarD7 Protein Deficiency Adversely Affects the Phosphatidylcholine Composition, Respiratory Activity, and Cristae Structure of Mitochondria. AB - Phosphatidylcholine (PC) is a major phospholipid of mitochondria, comprising 40 50% of both the outer and the inner membranes. However, PC must be imported from its production organelles because mitochondria lack the enzymes essential for PC biosynthesis. In a previous study, we found that StarD7 mediates the intracellular transfer of PC to mitochondria. Therefore, in this study, we analyzed the contribution of StarD7 to the maintenance of mitochondrial phospholipid content and function using siRNA-mediated knockdown and knock-out (KO) of the StarD7 gene in HEPA-1 cells. Real time analysis of respiratory activity demonstrated that the oxygen consumption rate and activity of mitochondrial complexes were impaired in StarD7-KD cells. To confirm these results, we established StarD7-KO HEPA-1 cells by double nicking using CRISPR/Cas9n. As expected, StarD7-KD and -KO cells showed a significant reduction in mitochondrial PC content. The ATP level and growth rate of KO cells were notably lower compared with wild-type cells when cultured in glucose-free galactose-containing medium to force cells to rely on mitochondrial ATP production. In KO cells, the level of the MTCO1 protein, a primary subunit of complex IV, was reduced without a concomitant decrease in its mRNA, but the level was restored when StarD7-I was overexpressed. StarD7-KO cells showed impaired formation of the mitochondrial supercomplexes and exhibited a disorganized cristae structure, with no changes in optic atrophy 1 protein. These findings indicate that StarD7 plays important roles in maintaining the proper composition of mitochondrial phospholipids as well as mitochondrial function and morphogenesis. PMID- 27694447 TI - Glue sniffing. AB - Inhalant abuse refers to the inhalation of volatile substances for their euphoric effects. Glues and adhesives have been abused inhalants for decades and so the term "glue sniffing" attached to the habit. These days many substances used are not adhesives and the most accurate title of "solvent abuse" has been given to this widespread and dangerous habit. The various methods of inhalational abuse include huffing, bagging, dusting, glading, and sniffing. We report one such case of a 22-year-old male who was found in an unresponsive state at his residence with a plastic cover around his head and empty tubes of "Fevibond" glue beside him. He died on the way to hospital. At autopsy, conjunctival and visceral congestion were found with pulmonary edema and petechiae over visceral pericardium. The viscera were analyzed, and the presence of toluene in his liver and blood was reported. PMID- 27694446 TI - Crystal Structures of the Nuclear Receptor, Liver Receptor Homolog 1, Bound to Synthetic Agonists. AB - Liver receptor homolog 1 (NR5A2, LRH-1) is an orphan nuclear hormone receptor that regulates diverse biological processes, including metabolism, proliferation, and the resolution of endoplasmic reticulum stress. Although preclinical and cellular studies demonstrate that LRH-1 has great potential as a therapeutic target for metabolic diseases and cancer, development of LRH-1 modulators has been difficult. Recently, systematic modifications to one of the few known chemical scaffolds capable of activating LRH-1 failed to improve efficacy substantially. Moreover, mechanisms through which LRH-1 is activated by synthetic ligands are entirely unknown. Here, we use x-ray crystallography and other structural methods to explore conformational changes and receptor-ligand interactions associated with LRH-1 activation by a set of related agonists. Unlike phospholipid LRH-1 ligands, these agonists bind deep in the pocket and do not interact with residues near the mouth nor do they expand the pocket like phospholipids. Unexpectedly, two closely related agonists with similar efficacies (GSK8470 and RJW100) exhibit completely different binding modes. The dramatic repositioning is influenced by a differential ability to establish stable face-to face pi-pi-stacking with the LRH-1 residue His-390, as well as by a novel polar interaction mediated by the RJW100 hydroxyl group. The differing binding modes result in distinct mechanisms of action for the two agonists. Finally, we identify a network of conserved water molecules near the ligand-binding site that are important for activation by both agonists. This work reveals a previously unappreciated complexity associated with LRH-1 agonist development and offers insights into rational design strategies.

PMID- 27694448 TI - Five-Year Outcomes of Breast Augmentation with Form-Stable Implants: Periareolar vs Transaxillary. AB - BACKGROUND: Form-stable 410 implants have the potential advantage of maintaining their anatomic form thanks to the cohesiveness of the gel. Furthermore, Biocell texturing appears to maximize adhesion and to allow for implant immobility. OBJECTIVES: To compare the rate of reoperations for transaxillary and periareolar approaches for breast augmentation. METHODS: This retrospective study consisted of 373 patients with a 5-year follow up. Patient demographics, self-perception and esteem, surgical technique, and implant characteristics were documented. The reasons for reoperation for both approaches were reviewed. RESULTS: Transaxillary breast augmentation was used in 302 patients (81%) and periareolar breast augmentation in 71 patients (19%). In the axillary group, 210 had subfascial placement (69.5%), and 92 patients had submuscular placement (30.5%). In the nipple-areolar complex group, 50 were subfascial (70.4%), and 21 were submuscular (29.6%). The reoperation rate for the patients operated on during this time and followed for 5 years was 11% (8 patients) for the nipple-areolar complex approach and 8.3% (25 patients) in the axillary group. Capsular contracture grade III or IV were the main causes for reoperation for any technique (4.2% nipple-areolar complex vs 3.3% axillary). Other reasons were implant rupture, seroma, infection, implant malrotation, implant malposition, and rippling. CONCLUSIONS: The rate of reoperations was similar to those described in the literature for this type of implant. There were no statistically significant differences between the various techniques, although the reoperation rate was significantly higher when a periareolar subfascial technique was used.

PMID- 27694451 TI - Incidence and Risk Factors for Major Surgical Site Infections in Aesthetic Surgery: Analysis of 129,007 Patients. AB - BACKGROUND: Surgical site infections (SSIs) represent one of the most common postoperative complications in patients undergoing aesthetic surgery. OBJECTIVES: This study reports the incidence and risk factors of major SSIs following aesthetic surgery. METHODS: A prospective cohort of patients who underwent aesthetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Primary outcome was occurrence of a major SSI requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis evaluated potential risk factors for SSIs including age, gender, body mass index (BMI), smoking, diabetes, type of surgical facility, procedure by body region, and combined procedures. RESULTS: A total of 129,007 patients were identified, of which 599 (0.46%) had a major SSI. Mean age (43.8 +/- 12.4 years vs 40.9 +/- 13.9 years, P < .01) and BMI (27.3 +/- 5.5 kg/m2 vs 24.3 +/- 4.6 kg/m2, P < .01) were higher in patients with SSIs. Patients with a SSI were more likely to be smokers (10.5% vs 8.2%, P = .04) and diabetic (4.5% vs 1.8%, P < .01). Females suffered more SSI than males (0.5% vs 0.3%, P = .02). Trunk/extremity procedures had a higher incidence of SSI compared to breast or face procedures (0.9% vs 0.2%, P < .01). On multivariate analysis, independent predictors of SSI included age (Relative Risk [RR] 1.01), female gender (RR 1.86), BMI (RR 1.07), smoking (RR 1.61), diabetes (RR 1.58), hospital or ambulatory surgery center procedures (RR 1.39), trunk/extremity procedures (RR 2.42), and combined procedures (RR 1.88). CONCLUSIONS: SSIs following cosmetic surgical procedures are associated with numerous independent predictors, which should be taken into consideration when counseling patients undergoing aesthetic surgery.

PMID- 27694454 TI - Auto-Rim Flap Technique for Lateral Crura Caudal Excess Treatment. AB - BACKGROUND: There are many variables that influence nose tip harmony. Even in a rhinoplasty that appears successful in profile, one may see nostril asymmetries, alar retractions, or irregularities in the soft triangle, and patients express their dissatisfaction with these simple deformities. OBJECTIVES: In this study, we define the ratio of caudal and cephalic excess of the lower lateral cartilage. We evaluate whether it is possible to eliminate nostril asymmetries and alar retractions by means of supporting the facet polygon with the help of a lower lateral cartilage auto-rim flap, a technique we have developed in our rhinoplasties. METHODS: The auto-rim flap was used successively on 498 primary rhinoplasty patients on whom the same surgeon operated between May 2013 and June 2015, performing marginal incisions. RESULTS: Of the 498 patients in the series, only 1 of the first 10 required a revision due to tip asymmetry related to the auto-rim flap. A minimal nostril asymmetry that did not require intervention occurred in 10 patients. In none of the patients could an increased alar retraction be seen postoperatively. All patients exhibited alar cartilage in the anatomically correct position. CONCLUSIONS: With the auto-rim flap technique, a part of the caudal excess of the alar cartilage remains as a flap in the facet region; therefore, there is no need in the cephalic region to perform more of an excision than what is strictly necessary.

Lessons From the Study of Social Cognition. AB - I call the attention of psychologists to the pivotal role of cultural psychology in extending and enriching research programs. I argue that it is not enough to simply acknowledge the importance of culture and urge psychologists to practice cultural psychology in their research. I deconstruct five assumptions about cultural psychology that seriously undermine its contribution to the building of a true psychological science, including that cultural psychology (a) is only about finding group differences, (b) does not appertain to group similarities, (c) concerns only group-level analysis, (d) is irrelevant to basic psychological processes, and (e) is used only to confirm the generalizability of theories. I discuss how cultural psychology can provide unique insights into psychological processes and further equip researchers with additional tools to understand human behavior. Drawing lessons from the 20 years of cultural research that my colleagues and I have done on the development of social cognition, including autobiographical memory, future thinking, self, and emotion knowledge, I demonstrate that incorporating cultural psychology into research programs is not only necessary but also feasible. PMID- 27694458 TI - Psychogenic Explanations of Physical Illness: Time to Examine the Evidence. AB - In some patients with chronic physical complaints, detailed examination fails to reveal a well-recognized underlying disease process. In this situation, the physician may suspect a psychological cause. In this review, we critically evaluated the evidence for this causal claim, focusing on complaints presenting as neurological disorders. There were four main conclusions. First, patients with these complaints frequently exhibit psychopathology but not consistently more often than patients with a comparable "organic" diagnosis, so a causal role cannot be inferred. Second, these patients report a high incidence of adverse life experiences, but again, there is insufficient evidence to indicate a causal role for any particular type of experience. Third, although psychogenic illnesses are believed to be more responsive to psychological interventions than comparable "organic" illnesses, there is currently no evidence to support this claim. Finally, recent evidence suggests that biological and physical factors play a much greater causal role in these illnesses than previously believed. We conclude that there is currently little evidential support for psychogenic theories of illness in the neurological domain. In future research, researchers need to take a wider view concerning the etiology of these illnesses. PMID- 27694457 TI - A Complex Network Perspective on Clinical Science. AB - Contemporary classification systems for mental disorders assume that abnormal behaviors are expressions of latent disease entities. An alternative to the latent disease model is the complex network approach. Instead of assuming that symptoms arise from an underlying disease entity, the complex network approach holds that disorders exist as systems of interrelated elements of a network. This approach also provides a framework for the understanding of therapeutic change. Depending on the structure of the network, change can occur abruptly once the network reaches a critical threshold (the tipping point). Homogeneous and highly connected networks often recover more slowly from local perturbations when the network approaches the tipping point, potentially making it possible to predict treatment change, relapse, and recovery. In this article, we discuss the complex network approach as an alternative to the latent disease model and its implications for classification, therapy, relapse, and recovery. PMID- 27694460 TI - Introduction to Optimizing Learning in College: Tips From Cognitive Psychology. PMID- 27694459 TI - Social Climate Science: A New Vista for Psychological Science. AB - The recent Paris Agreement to limit greenhouse gas emissions, adopted by 195 nations at the 2015 United Nations Climate Change Conference, signaled unprecedented commitment by world leaders to address the human social aspects of climate change. Indeed, climate change increasingly is recognized by scientists and policymakers as a social issue requiring social solutions. However, whereas psychological research on intrapersonal and some group-level processes (e.g., political polarization of climate beliefs) has flourished, research into other social processes-such as an understanding of how nonpartisan social identities, cultural ideologies, and group hierarchies shape public engagement on climate change-has received substantially less attention. In this article, we take stock of current psychological approaches to the study of climate change to explore what is "social" about climate change from the perspective of psychology. Drawing from current interdisciplinary perspectives and emerging empirical findings within psychology, we identify four distinct features of climate change and three sets of psychological processes evoked by these features that are fundamentally social and shape both individual and group responses to climate change. Finally, we consider how a more nuanced understanding of the social underpinnings of climate change can stimulate new questions and advance theory within psychology. PMID- 27694461 TI - Optimizing Learning in College: Tips From Cognitive Psychology. AB - Every fall, thousands of college students begin their first college courses, often in large lecture settings. Many students, even those who work hard, flounder. What should students be doing differently? Drawing on research in cognitive psychology and our experience as educators, we provide suggestions about how students should approach taking a course in college. We discuss time management techniques, identify the ineffective study strategies students often use, and suggest more effective strategies based on research in the lab and the classroom. In particular, we advise students to space their study sessions on a topic and to quiz themselves, as well as using other active learning strategies while reading. Our goal was to provide a framework for students to succeed in college classes. PMID- 27694462 TI - Introduction to the Special Section on Improving Research Practices: Thinking Deeply Across the Research Cycle. PMID- 27694463 TI - Optimizing Research Payoff. AB - In this article, we present a model for determining how total research payoff depends on researchers' choices of sample sizes, alpha levels, and other parameters of the research process. The model can be used to quantify various trade-offs inherent in the research process and thus to balance competing goals, such as (a) maximizing both the number of studies carried out and also the statistical power of each study, (b) minimizing the rates of both false positive and false negative findings, and (c) maximizing both replicability and research efficiency. Given certain necessary information about a research area, the model can be used to determine the optimal values of sample size, statistical power, rate of false positives, rate of false negatives, and replicability, such that overall research payoff is maximized. More specifically, the model shows how the optimal values of these quantities depend upon the size and frequency of true effects within the area, as well as the individual payoffs associated with particular study outcomes. The model is particularly relevant within current discussions of how to optimize the productivity of scientific research, because it shows which aspects of a research area must be considered and how these aspects combine to determine total research payoff. PMID- 27694464 TI - Graphical Descriptives: A Way to Improve Data Transparency and Methodological Rigor in Psychology. AB - Several calls have recently been issued to the social sciences for enhanced transparency of research processes and enhanced rigor in the methodological treatment of data and data analytics. We propose the use of graphical descriptives (GDs) as one mechanism for responding to both of these calls. GDs provide a way to visually examine data. They serve as quick and efficient tools for checking data distributions, variable relations, and the potential appropriateness of different statistical analyses (e.g., do data meet the minimum assumptions for a particular analytic method). Consequently, we believe that GDs can promote increased transparency in the journal review process, encourage best practices for data analysis, and promote a more inductive approach to understanding psychological data. We illustrate the value of potentially including GDs as a step in the peer-review process and provide a user-friendly online resource (www.graphicaldescriptives.org) for researchers interested in including data visualizations in their research. We conclude with suggestions on how GDs can be expanded and developed to enhance transparency. PMID- 27694465 TI - Increasing Transparency Through a Multiverse Analysis. AB - Empirical research inevitably includes constructing a data set by processing raw data into a form ready for statistical analysis. Data processing often involves choices among several reasonable options for excluding, transforming, and coding data. We suggest that instead of performing only one analysis, researchers could perform a multiverse analysis, which involves performing all analyses across the whole set of alternatively processed data sets corresponding to a large set of reasonable scenarios. Using an example focusing on the effect of fertility on religiosity and political attitudes, we show that analyzing a single data set can be misleading and propose a multiverse analysis as an alternative practice. A multiverse analysis offers an idea of how much the conclusions change because of arbitrary choices in data construction and gives pointers as to which choices are most consequential in the fragility of the result. PMID- 27694466 TI - Conducting Meta-Analyses Based on p Values: Reservations and Recommendations for Applying p-Uniform and p-Curve. AB - Because of overwhelming evidence of publication bias in psychology, techniques to correct meta-analytic estimates for such bias are greatly needed. The methodology on which the p-uniform and p-curve methods are based has great promise for providing accurate meta-analytic estimates in the presence of publication bias. However, in this article, we show that in some situations, p-curve behaves erratically, whereas p-uniform may yield implausible estimates of negative effect size. Moreover, we show that (and explain why) p-curve and p-uniform result in overestimation of effect size under moderate-to-large heterogeneity and may yield unpredictable bias when researchers employ p-hacking. We offer hands-on recommendations on applying and interpreting results of meta-analyses in general and p-uniform and p-curve in particular. Both methods as well as traditional methods are applied to a meta-analysis on the effect of weight on judgments of importance. We offer guidance for applying p-uniform or p-curve using R and a user-friendly web application for applying p-uniform. PMID- 27694467 TI - Adjusting for Publication Bias in Meta-Analysis: An Evaluation of Selection Methods and Some Cautionary Notes. AB - We review and evaluate selection methods, a prominent class of techniques first proposed by Hedges (1984) that assess and adjust for publication bias in meta analysis, via an extensive simulation study. Our simulation covers both restrictive settings as well as more realistic settings and proceeds across multiple metrics that assess different aspects of model performance. This evaluation is timely in light of two recently proposed approaches, the so-called p-curve and p-uniform approaches, that can be viewed as alternative implementations of the original Hedges selection method approach. We find that the p-curve and p-uniform approaches perform reasonably well but not as well as the original Hedges approach in the restrictive setting for which all three were designed. We also find they perform poorly in more realistic settings, whereas variants of the Hedges approach perform well. We conclude by urging caution in the application of selection methods: Given the idealistic model assumptions underlying selection methods and the sensitivity of population average effect size estimates to them, we advocate that selection methods should be used less for obtaining a single estimate that purports to adjust for publication bias ex post and more for sensitivity analysis-that is, exploring the range of estimates that result from assuming different forms of and severity of publication bias.

AB - Finkel, Rusbult, Kumashiro, and Hannon (2002, Study 1) demonstrated a causal link between subjective commitment to a relationship and how people responded to hypothetical betrayals of that relationship. Participants primed to think about their commitment to their partner (high commitment) reacted to the betrayals with reduced exit and neglect responses relative to those primed to think about their independence from their partner (low commitment). The priming manipulation did not affect constructive voice and loyalty responses. Although other studies have demonstrated a correlation between subjective commitment and responses to betrayal, this study provides the only experimental evidence that inducing changes to subjective commitment can causally affect forgiveness responses. This Registered Replication Report (RRR) meta-analytically combines the results of 16 new direct replications of the original study, all of which followed a standardized, vetted, and preregistered protocol. The results showed little effect of the priming manipulation on the forgiveness outcome measures, but it also did not observe an effect of priming on subjective commitment, so the manipulation did not work as it had in the original study. We discuss possible explanations for the discrepancy between the findings from this RRR and the original study. PMID- 27694470 TI - The conundrum of malaria chemoprophylaxis.

PMID- 27694471 TI - IL-17A-mediated expression of epithelial IL-17C promotes inflammation during acute Pseudomonas aeruginosa pneumonia. AB - Lung epithelial cells are suggested to promote pathogen-induced pulmonary inflammation by the release of chemokines, resulting in enhanced recruitment of circulating leukocytes. Recent studies have shown that the interleukin-17C (IL 17C) regulates innate immune functions of epithelial cells in an autocrine manner. The aim of this study was to investigate the contribution of IL-17C to pulmonary inflammation in a mouse model of acute Pseudomonas aeruginosa pneumonia. Infection with P. aeruginosa resulted in an increased expression of IL 17C in lung tissue of wild-type mice. Numbers of neutrophils and the expression of the neutrophil-recruiting chemokines keratinocyte-derived chemokine and macrophage inflammatory protein 2 were significantly decreased in lungs of IL-17C deficient (IL-17C-/-) mice infected with P. aeruginosa at 24 h. Systemic concentrations of interleukin-6 (IL-6) were significantly decreased in infected IL-17C-/- mice at 24 h and the survival of IL-17C-/- mice was significantly increased at 48 h. The expression of IL-17C was reduced in infected mice deficient for interleukin-17A (IL-17A), whereas pulmonary concentrations of IL 17A were not affected by the deficiency for IL-17C. Stimulation of primary alveolar epithelial cells with IL-17A resulted in a significantly increased expression of IL-17C in vitro. Our data suggest that IL-17A-mediated expression of epithelial IL-17C amplifies the release of chemokines by epithelial cells and thereby contributes to the recruitment of neutrophils and systemic inflammation during acute P. aeruginosa pneumonia. PMID- 27694473 TI - Simvastatin prevents and reverses chronic pulmonary hypertension in newborn rats via pleiotropic inhibition of RhoA signaling. AB - Chronic neonatal pulmonary hypertension (PHT) frequently results in early death. Systemically administered Rho-kinase (ROCK) inhibitors prevent and reverse chronic PHT in neonatal rats, but at the cost of severe adverse effects, including systemic hypotension and growth restriction. Simvastatin has pleiotropic inhibitory effects on isoprenoid intermediates that may limit activity of RhoA, which signals upstream of ROCK. We therefore hypothesized that statin treatment would safely limit pulmonary vascular RhoA activity and prevent and reverse experimental chronic neonatal PHT via downstream inhibitory effects on pathological ROCK activity. Sprague-Dawley rats in normoxia (room air) or moderate normobaric hypoxia (13% O2) received simvastatin (2 mg.kg-1.day-1 ip) or vehicle from postnatal days 1-14 (prevention protocol) or from days 14-21 (rescue protocol). Chronic hypoxia increased RhoA and ROCK activity in lung tissue. Simvastatin reduced lung content of the isoprenoid intermediate farnesyl pyrophosphate and decreased RhoA/ROCK signaling in the hypoxia-exposed lung. Preventive or rescue treatment of chronic hypoxia-exposed animals with simvastatin decreased pulmonary vascular resistance, right ventricular hypertrophy, and pulmonary arterial remodeling. Preventive simvastatin treatment improved weight gain, did not lower systemic blood pressure, and did not cause apparent toxic effects on skeletal muscle, liver or brain. Rescue therapy with simvastatin improved exercise capacity. We conclude that simvastatin limits RhoA/ROCK activity in the chronic hypoxia-exposed lung, thus preventing or ameliorating hemodynamic and structural markers of chronic PHT and improving long term outcome, without causing adverse effects. PMID- 27694474 TI - Of mice and men: correlations between microRNA-17~92 cluster expression and promoter methylation in severe bronchopulmonary dysplasia. AB - We previously demonstrated that decreased miR-17~92 cluster expression was 1) present in lungs from human infants who died with bronchopulmonary dysplasia (BPD); 2) inversely correlated with DNA methyltransferase (DNMT) expression and promoter methylation; and 3) correlated with a subsequent diagnosis of BPD at 36 wk gestational age. We tested the hypothesis that plasma miR-17 levels would be lowest in infants who ultimately develop severe BPD. Secondly, we utilized our well-characterized murine model of severe BPD that combines perinatal inflammation with postnatal hyperoxia to test the hypothesis that alterations in lung miR-17~92, DNMT, and promoter methylation in our model would mirror our findings in tissues from premature human infants. Plasma was obtained during the first 5 days of life from premature infants born <=32 wk gestation. Lung tissues were harvested from mice exposed to maternal inflammation and neonatal hyperoxia for 14 days after birth. miR-17~92 cluster expression and DNA methyltransferase expression were measured by qRT-PCR, and promoter methylation was assessed by Methyl-Profiler assay. Plasma miR-17 levels are significantly lower in the first week of life in human infants who develop severe BPD compared with mild or moderate BPD. Data from our severe BPD murine model reveal that lung miR-17~92 cluster expression is significantly attenuated, and levels inversely correlated with DNMT expression and miR-17~92 cluster promoter methylation. Collectively, our data support a plausible role for epigenetically altered miR-17~92 cluster in the pathogenesis of severe BPD. PMID- 27694472 TI - Neutrophils promote alveolar epithelial regeneration by enhancing type II pneumocyte proliferation in a model of acid-induced acute lung injury. AB - Alveolar epithelial regeneration is essential for resolution of the acute respiratory distress syndrome (ARDS). Although neutrophils have traditionally been considered mediators of epithelial damage, recent studies suggest they promote type II pneumocyte (AT2) proliferation, which is essential for regenerating alveolar epithelium. These studies did not, however, evaluate this relationship in an in vivo model of alveolar epithelial repair following injury. To determine whether neutrophils influence alveolar epithelial repair in vivo, we developed a unilateral acid injury model that creates a severe yet survivable injury with features similar to ARDS. Mice that received injections of the neutrophil-depleting Ly6G antibody had impaired AT2 proliferation 24 and 72 h after acid instillation, which was associated with decreased reepithelialization and increased alveolar protein concentration 72 h after injury. As neutrophil depletion itself may alter the cytokine response, we questioned the contribution of neutrophils to alveolar epithelial repair in neutropenic granulocyte-colony stimulating factor (G-CSF)-/- mice. We found that the loss of G-CSF recapitulated the neutrophil response of Ly6G-treated mice and was associated with defective alveolar epithelial repair, similar to neutrophil-depleted mice, and was reversed by administration of exogenous G-CSF. To approach the mechanisms, we employed an unbiased protein analysis of bronchoalveolar lavage fluid from neutrophil depleted and neutrophil-replete mice 12 h after inducing lung injury. Pathway analysis identified significant differences in multiple signaling pathways that may explain the differences in epithelial repair. These data emphasize an important link between the innate immune response and tissue repair in which neutrophils promote alveolar epithelial regeneration. PMID- 27694475 TI - Attenuated heme oxygenase-1 responses predispose the elderly to pulmonary nontuberculous mycobacterial infections. AB - Pulmonary infections with nontuberculous mycobacteria (P-NTM), such as by Mycobacterium avium complex (M. avium), are increasingly found in the elderly, but the underlying mechanisms are unclear. Recent studies suggest that adaptive immunity is necessary, but not sufficient, for host defense against mycobacteria. Heme oxygenase-1 (HO-1) has been recognized as a critical modulator of granuloma formation and programmed cell death in mycobacterial infections. Old mice (18-21 mo) infected with M. avium had attenuated HO-1 response with diffuse inflammation, high burden of mycobacteria, poor granuloma formation, and decreased survival (45%), while young mice (4-6 mo) showed tight, well-defined granuloma, increased HO-1 expression, and increased survival (95%). To further test the role of HO-1 in increased susceptibility to P-NTM infections in the elderly, we used old and young HO-1+/+ and HO-1-/- mice. The transcriptional modulation of the JAK/STAT signaling pathway in HO-1-/- mice due to M. avium infection demonstrated similarities to infected wild-type old mice with upregulation of SOCS3 and inhibition of Bcl2. Higher expression of SOCS3 with downregulation of Bcl2 resulted in higher macrophage death via cellular necrosis. Finally, peripheral blood monocytes (PBMCs) from elderly patients with P-NTM also demonstrated attenuated HO-1 responses after M. avium stimulation and increased cell death due to cellular necrosis (9.69% +/- 2.02) compared with apoptosis (4.75% +/- 0.98). The augmented risk for P-NTM in the elderly is due, in part, to attenuated HO-1 responses, subsequent upregulation of SOCS3, and inhibition of Bcl2, leading to programmed cell death of macrophages, and sustained infection.

(Metchnikovellidae). AB - Metchnikovellidae are a group of unusual microsporidians that lack some of the defining ultrastructural features characteristic of derived Microsporidia and are thought to be one of their earliest-branching lineages. The basal position of metchnikovellids was never confirmed by molecular phylogeny in published research, and thus far no genomic data for this group were available. In this work, we obtain a partial genome of metchnikovellid Amphiamblys sp. using multiple displacement amplification, next-generation sequencing, and metagenomic binning approaches. The partial genome, which we estimate to be close to 90% complete, displays genome compaction on par with gene-dense microsporidian genomes, but contains an unusual repertoire of unique repeat elements. Phylogenetic analyses of multigene datasets place Amphiamblys sp. as the first branch of the microsporidian lineage following the divergence of a mitochondriate microsporidian Mitosporidium. We find evidence for a mitochondrial remnant presumably functionally equivalent to a mitosome in Amphiamblys sp. and the common enzymatic complement for microsporidian anaerobic metabolism. Comparative genomic analyses identify the conservation of components for clathrin vesicle formation as one of the key features distinguishing the metchnikovellid from its highly derived relatives. The presented data confirm the notion of Metchnikovellidae as a less derived microsporidian group, and provide an additional stepping stone for reconstruction of an evolutionary transition from the early diverging parasitic fungi to derived Microsporidia.

AB - Zika virus and dengue virus serotype 2 were isolated from a patient with travel to Haiti who developed fever, rash, arthralgias, and conjunctivitis.

PMID- 27694478 TI - Role of FEN1 S187 phosphorylation in counteracting oxygen-induced stress and regulating postnatal heart development. AB - Flap endonuclease 1 (FEN1) phosphorylation is proposed to regulate the action of FEN1 in DNA repair as well as Okazaki fragment maturation. However, the biologic significance of FEN1 phosphorylation in response to DNA damage remains unknown. Here, we report an in vivo role for FEN1 phosphorylation, using a mouse line carrying S187A FEN1, which abolishes FEN1 phosphorylation. Although S187A mouse embryonic fibroblast cells showed normal proliferation under low oxygen levels (2%), the mutant cells accumulated oxidative DNA damage, activated DNA damage checkpoints, and showed G1-phase arrest at atmospheric oxygen levels (21%). This suggests an essential role for FEN1 phosphorylation in repairing oxygen-induced DNA damage and maintaining proper cell cycle progression. Consistently, the mutant cardiomyocytes showed G1-phase arrest due to activation of the p53 mediated DNA damage response at the neonatal stage, which reduces the proliferation potential of the cardiomyocytes and impairs heart development. Nearly 50% of newborns with the S187A mutant died in the first week due to failure to undergo the peroxisome proliferator-activated receptor signaling dependent switch from glycolysis to fatty acid oxidation. The adult mutant mice developed dilated hearts and showed significantly shorter life spans. Altogether, our results reveal an important role of FEN1 phosphorylation to counteract oxygen induced stress in the heart during the fetal-to-neonatal transition.-Zhou, L., Dai, H., Wu, J., Zhou, M., Yuan, H., Du, J., Yang, L., Wu, X., Xu, H., Hua, Y., Xu, J., Zheng, L., Shen, B.

PMID- 27694482 TI - Reply to Cohen et al. PMID- 27694483 TI - Antibiotic Use in Small Community Hospitals. AB - BACKGROUND: Antibiotic use and misuse is driving drug resistance. Much of US healthcare takes place in small community hospitals (SCHs); 70% of all US hospitals have <200 beds. Antibiotic use in SCHs is poorly described. We evaluated antibiotic use using data from the National Healthcare and Safety Network antimicrobial use option from the Centers for Disease Control and Prevention. METHODS: We used Intermountain Healthcare's monthly antibiotic use reports for 19 hospitals from 2011 to 2013. Hospital care units were categorized as intensive care, medical/surgical, pediatric, or miscellaneous. Antibiotics were categorized based on spectrum of coverage. Antibiotic use rates, expressed as days of therapy per 1000 patient-days (DOT/1000PD), were calculated for each SCH and compared with rates in large community hospitals (LCHs). Negative binomial regression was used to relate antibiotic use to predictor variables. RESULTS: Total antibiotic use rates varied widely across the 15 SCHs (median, 436 DOT/1000PD; range, 134-671 DOT/1000PD) and were similar to rates in 4 LCHs (509 DOT/1000PD; 406-597 DOT/1000PD). The proportion of patient-days spent in the respective unit types varied substantially within SCHs and had a large impact on facility-level rates. Broad-spectrum antibiotics accounted for 26% of use in SCHs (range, 8%-36%), similar to the proportion in LCHs (32%; range, 26%-37%). Case mix index, proportion of patient-days in specific unit types, and season were significant predictors of antibiotic use. CONCLUSIONS: There is substantial variation in patterns of antibiotic use among SCHs. Overall usage in SCHs is similar to usage in LCHs. Small hospitals need to become a focus of stewardship efforts. PMID- 27694484 TI - Patient-reported outcome measure for neuromyelitis optica: pretesting of preliminary instrument and protocol for further development in accordance with international guidelines. AB - OBJECTIVE: This study outlines the development of a patient-reported outcome measure (PROM), an instrument to obtain self-reported health status for neuromyeltis optica (NMO), a disabling neurological condition. DESIGN: Development was conducted in accordance with international guidance for PROMs including systematic review of existing literature, item generation guided by qualitative interviews, health-related quality of life conceptual framework and clinical expert panel and cognitive interviews with NMO patients. SETTING: Participants were identified through a national NMO clinic in a tertiary NHS neurosciences service. PARTICIPANTS: 15 individuals with NMO participated in cognitive interviews requiring review and ranking of proposed PROM items and qualitative feedback on content, layout and response options. RESULTS: Participants endorsed the draft instrument as reflecting their experience of the condition and as being easy to understand. Rating and ranking of item relevance and importance reduced the draft instrument from 106 to 48 items. Participant feedback on overlapping items eliminated a further 2 items and resulted in a preliminary instrument of 46 items. As a direct result of participant feedback ordering of the 10 domains was revised, a 4 option Likert scale was employed and a 4-week recall period for impact of symptoms was selected. CONCLUSIONS: A 46 item instrument developed in accordance with international PROM development guidelines through literature review, developed by subject matter experts and refined through pretesting examining content validity provides a preliminary measure for assessing patient-report of health status in NMO. Further evaluation is proposed including sensitivity to clinical change, and international contributions to evaluating the measure are encouraged. PMID- 27694485 TI - Effectiveness of the 'Back-to-Sleep' campaigns among healthcare professionals in the past 20 years: a systematic review. AB - OBJECTIVES: From the late 1980s 'Back-to-Sleep' (BTS) campaigns were run in most developed countries to increase awareness of the supine position's protective effect against sleep-related infant deaths. Once the media awareness-raising action associated with these campaigns ended, healthcare professionals' role became crucial. The goal of this paper is to determine if healthcare professionals' knowledge and parent advice consistent with evidence-based infant sleep recommendations have changed over the past 20 years. SETTING: All studies investigating healthcare professionals' knowledge and/or advice to parents were included in a systematic review. The search was performed in PubMed and in MEDLINE, and 21 studies were identified. RESULTS: The correctness of healthcare professionals' knowledge and parent advice about the supine sleeping position increased over the past 20 years. However, the percentage of those aware that parents should avoid putting their babies to sleep in a prone position is decreasing over time: from about 97% in the 1990s to about 90% at the end of the 2000s. CONCLUSIONS: The effectiveness of the BTS campaigns in publicising the benefits of the supine position is confirmed by this paper. More and more healthcare professionals know that it is the best position to reduce the risk of sleep-related deaths and they recommend it exclusively. However, the decrease in the knowledge about non-prone positions suggests that the campaigns may not have focused enough on the dangers of the prone position. PMID- 27694486 TI - Implementing the RISE second victim support programme at the Johns Hopkins Hospital: a case study. AB - BACKGROUND: Second victims are healthcare workers who experience emotional distress following patient adverse events. Studies indicate the need to develop organisational support programmes for these workers. The RISE (Resilience In Stressful Events) programme was developed at the Johns Hopkins Hospital to provide this support. OBJECTIVE: To describe the development of RISE and evaluate its initial feasibility and subsequent implementation. Programme phases included (1) developing the RISE programme, (2) recruiting and training peer responders, (3) pilot launch in the Department of Paediatrics and (4) hospital-wide implementation. METHODS: Mixed-methods study, including frequency counts of encounters, staff surveys and evaluations by RISE peer responders. Descriptive statistics were used to summarise demographic characteristics and proportions of responses to categorical, Likert and ordinal scales. Qualitative analysis and coding were used to analyse open-ended responses from questionnaires and focus groups. RESULTS: A baseline staff survey found that most staff had experienced an unanticipated adverse event, and most would prefer peer support. A total of 119 calls, involving ~500 individuals, were received in the first 52 months. The majority of calls were from nurses, and very few were related to medical errors (4%). Peer responders reported that the encounters were successful in 88% of cases and 83.3% reported meeting the caller's needs. Low awareness of the programme was a barrier to hospital-wide expansion. However, over the 4 years, the rate of calls increased from ~1-4 calls per month. The programme evolved to accommodate requests for group support. CONCLUSIONS: Hospital staff identified the need for a multidisciplinary peer support programme for second victims. Peer responders reported success in responding to calls, the majority of which were for adverse events rather than for medical errors. The low initial volume of calls emphasises the importance of promoting awareness of the value of emotional support and the availability of the programme. PMID- 27694487 TI - Association of neck circumference with general and abdominal obesity in children and adolescents: the weight disorders survey of the CASPIAN-IV study. AB - OBJECTIVES: This study aimed to evaluate the association of neck circumference (NC) with obesity to determine the sex-specific and age-specific optimal cut-off points of this measure in association with obesity in a national sample of the Iranian paediatric population. METHODS: This survey on weight disorders was conducted among a national sample of Iranian children and adolescents, aged 6-18 years. Using the area under the curve (AUC) of the receiver operator characteristic curves, we evaluated the association of NC with general and abdominal obesity. RESULTS: This national survey was conducted among 23 043 school students (50.8% boys) with a mean age (SD) of 12.55 (3.31) years. A significant association was documented between NC and other anthropometric measures in both sexes and in the whole population. In all age groups and genders, NC performed relatively well in classifying participants to overweight (AUC: 0.67 to 0.75, p<0.001), general obesity (AUC: 0.81 to 0.85, p<0.001) and abdominal obesity (AUC: 0.73 to 0.78, p<0.001). CONCLUSIONS: NC can be considered as a simple time-saving clinical tool for obesity detection in large population based studies in children and adolescents. It is significantly correlated with indices of adiposity and can reliably identify children with general and abdominal obesity in the Iranian paediatric population. PMID- 27694488 TI - Identification and outcomes of clinical phenotypes in amyotrophic lateral sclerosis/motor neuron disease: Australian National Motor Neuron Disease observational cohort. AB - OBJECTIVE: To capture the clinical patterns, timing of key milestones and survival of patients presenting with amyotrophic lateral sclerosis/motor neuron disease (ALS/MND) within Australia. METHODS: Data were prospectively collected and were timed to normal clinical assessments. An initial registration clinical report form (CRF) and subsequent ongoing assessment CRFs were submitted with a completion CRF at the time of death. DESIGN: Prospective observational cohort study. PARTICIPANTS: 1834 patients with a diagnosis of ALS/MND were registered and followed in ALS/MND clinics between 2005 and 2015. RESULTS: 5 major clinical phenotypes were determined and included ALS bulbar onset, ALS cervical onset and ALS lumbar onset, flail arm and leg and primary lateral sclerosis (PLS). Of the 1834 registered patients, 1677 (90%) could be allocated a clinical phenotype. ALS bulbar onset had a significantly lower length of survival when compared with all other clinical phenotypes (p<0.004). There were delays in the median time to diagnosis of up to 12 months for the ALS phenotypes, 18 months for the flail limb phenotypes and 19 months for PLS. Riluzole treatment was started in 78-85% of cases. The median delays in initiating riluzole therapy, from symptom onset, varied from 10 to 12 months in the ALS phenotypes and 15-18 months in the flail limb phenotypes. Percutaneous endoscopic gastrostomy was implemented in 8-36% of ALS phenotypes and 2-9% of the flail phenotypes. Non-invasive ventilation was started in 16-22% of ALS phenotypes and 21-29% of flail phenotypes. CONCLUSIONS: The establishment of a cohort registry for ALS/MND is able to determine clinical phenotypes, survival and monitor time to key milestones in disease progression. It is intended to expand the cohort to a more population-based registry using opt out methodology and facilitate data linkage to other national registries. PMID- 27694489 TI - Effects of a nutrition plus exercise programme on physical function in sarcopenic obese elderly people: study protocol for a randomised controlled trial. AB - INTRODUCTION: With a rapidly ageing population, sarcopenic obesity, defined as decreased muscle mass and function combined with increased body fat, is a complex health problem. Although sarcopenic obesity contributes to a decline in physical function and exacerbates frailty in older adults, evidence from clinical trials about the effect of exercise and nutrition on this complex syndrome in Chinese older adults is lacking. METHODS AND ANALYSIS: We devised a study protocol for a single-blind randomised controlled trial. Sarcopenia is described as age-related decline in muscle mass plus low muscle strength and/or low physical performance. Obesity is defined as a percentage of body fat above the 60th centile. Ninety-two eligible participants will be randomly assigned to a control group, nutrition group, exercise group and nutrition plus exercise group to receive an 8-week intervention and 12-week follow-up. The primary outcomes will be the change in short physical performance battery scores, grip strength and 6 m usual gait speed. The secondary outcomes will include basic activities of daily living scores, instrumental activity daily living scores, body composition and body anthropometric indexes. For all main analyses, the principle of intention-to treat will be used. ETHICS AND DISSEMINATION: This study was approved by the medical ethics committee of Zhejiang Hospital on 25 November 2015. The study will present data targeting the clinical effects of nutrition and exercise on physical function and body composition in a Chinese older population with sarcopenic obesity. The results will help to provide important clinical evidence of the role of complex non-pharmaceutical interventions for sarcopenic obese older people. The findings of this study will be submitted to peer-reviewed medical journals for publication and presented at relevant academic conferences. TRIAL REGISTRATION NUMBER: ChiCTR-IOR-15007501; Pre-results. PMID- 27694490 TI - Effect of vitreomacular adhesion and vitreous gel on age-related reduction of macular thickness: a retrospective observational study. AB - OBJECTIVE: To investigate the effects of vitreomacular adhesion (VMA), vitreomacular separation (VMS) and absence of vitreous gel due to vitrectomy on macular thickness measured in the spectral domain optical coherence tomographic (SD-OCT) images. DESIGN: A longitudinal, retrospective, observational study. SETTING: Secondary multicentre study. PARTICIPANTS: 218 eyes of 218 healthy patients and 119 vitrectomised eyes of 119 patients were studied. The healthy individuals were classified into a VMA group (54 eyes) and a VMS group (164 eyes), while the vitrectomised patients were classified into an internal limiting membrane (ILM)-on group (26 eyes) and an ILM-off group (93 eyes). In all participants, 2 Cirrus HD-OCT recordings were made with an average interval of 36 months (range 24-60 months). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measure was the rate of change in macular thickness in the central sector. The secondary outcomes were the rates of change in macular thickness in the inner 4 sectors. RESULTS: The annual rate of change in the macular thickness of the central sector was 0.76+/-1.8 um/year in the VMA group, -0.58+/-2.3 um/year in the VMS group, -1.57+/-1.9 um/year in the ILM-on group and -0.86+/-3.1 um/year in the ILM-off group. There was a significant difference between the rate of the central sector thickness change in the VMA and VMS groups (p=0.0001). The presence of VMA was a significant factor associated with an increase in the central sector thickness (p=0.0055). When the healthy and ILM-on groups were compared, the rate of decrease in the central sector thickness was faster in the ILM-on group (p=0.0043). Multiple regression analyses showed that not peeling the ILM during the vitrectomy was a significant factor associated with a decrease in the central sector thickness (p=0.044). CONCLUSIONS: The presence of a VMA and a vitreous gel may help restrain the macular thickness reduction. PMID- 27694492 TI - Inositol-Triphosphate 3-Kinase C Mediates Inflammasome Activation and Treatment Response in Kawasaki Disease. AB - Kawasaki disease (KD) is a multisystem vasculitis that predominantly targets the coronary arteries in children. Phenotypic similarities between KD and recurrent fever syndromes point to the potential role of inflammasome activation in KD. Mutations in NLRP3 are associated with recurrent fever/autoinflammatory syndromes. We show that the KD-associated genetic polymorphism in inositol triphosphate 3-kinase C (ITPKC) (rs28493229) has important functional consequences, governing ITPKC protein levels and thereby intracellular calcium, which in turn regulates NLRP3 expression and production of IL-1beta and IL-18. Analysis of transcript abundance, protein levels, and cellular response profiles from matched, serial biospecimens from a cohort of genotyped KD subjects points to the critical role of ITPKC in mediating NLRP3 inflammasome activation. Treatment failure in those with the high-risk ITPKC genotype was associated with the highest basal and stimulated intracellular calcium levels and with increased cellular production of IL-1beta and IL-18 and higher circulating levels of both cytokines. Mechanistic studies using Itpkc-deficient mice in a disease model support the genomic, cellular, and clinical findings in affected children. Our findings provide the mechanism behind the observed efficacy of rescue therapy with IL-1 blockade in recalcitrant KD, and we identify that regulation of calcium mobilization is fundamental to the underlying immunobiology in KD. PMID- 27694491 TI - Upregulation of IFN-Inducible and Damage-Response Pathways in Chronic Graft versus-Host Disease. AB - Although chronic graft-versus-host disease (CGVHD) is the primary nonrelapse complication of allogeneic transplantation, understanding of its pathogenesis is limited. To identify the main operant pathways across the spectrum of CGVHD, we analyzed gene expression in circulating monocytes, chosen as in situ systemic reporter cells. Microarrays identified two interrelated pathways: 1) IFN inducible genes, and 2) innate receptors for cellular damage. Corroborating these with multiplex RNA quantitation, we found that multiple IFN-inducible genes (affecting lymphocyte trafficking, differentiation, and Ag presentation) were concurrently upregulated in CGVHD monocytes compared with normal subjects and non CGVHD control patients. IFN-inducible chemokines were elevated in both lichenoid and sclerotic CGHVD plasma and were linked to CXCR3+ lymphocyte trafficking. Furthermore, the levels of the IFN-inducible genes CXCL10 and TNFSF13B (BAFF) were correlated at both the gene and the plasma levels, implicating IFN induction as a factor in elevated BAFF levels in CGVHD. In the second pathway, damage /pathogen-associated molecular pattern receptor genes capable of inducing type I IFN were upregulated. Type I IFN-inducible MxA was expressed in proportion to CGVHD activity in skin, mucosa, and glands, and expression of TLR7 and DDX58 receptor genes correlated with upregulation of type I IFN-inducible genes in monocytes. Finally, in serial analyses after transplant, IFN-inducible and damage response genes were upregulated in monocytes at CGVHD onset and declined upon therapy and resolution in both lichenoid and sclerotic CGVHD patients. This interlocking analysis of IFN-inducible genes, plasma analytes, and tissue immunohistochemistry strongly supports a unifying hypothesis of induction of IFN by innate response to cellular damage as a mechanism for initiation and persistence of CGVHD. PMID- 27694493 TI - MK2/3 Are Pivotal for IL-33-Induced and Mast Cell-Dependent Leukocyte Recruitment and the Resulting Skin Inflammation. AB - The IL-1R family member IL-33R mediates Fcepsilon-receptor-I (FcepsilonRI) independent activation of mast cells leading to NF-kappaB activation and consequently the production of cytokines. IL-33 also induces the activation of MAPKs, such as p38. We aimed to define the relevance of the p38-targets, the MAPK activated protein kinases 2 and 3 (MK2 and MK3) in IL-33-induced signaling and the resulting mast cell effector functions in vitro and in vivo. We demonstrate that the IL-33-induced IL-6 and IL-13 production strongly depends on the MK2/3 mediated activation of ERK1/2 and PI3K signaling. Furthermore, in the presence of the stem cell factors, IL-33 did induce an MK2/3-, ERK1/2- and PI3K-dependent production of TNF-alpha. In vivo, the loss of MK2/3 in mast cells decreased the IL-33-induced leukocyte recruitment and the resulting skin inflammation. Therefore, the MK2/3-dependent signaling in mast cells is essential to mediate IL 33-induced inflammatory responses. Thus, MK2/3 are potential therapeutic targets for suppression of IL-33-induced inflammation skin diseases such as psoriasis.

AB - The endocannabinoid system comprises cannabinoid receptors 1 and 2 (CB1 and CB2), their endogenous ligands, anandamide (AEA) and 2-arachidonoylglycerol, and metabolic enzymes of these ligands. The endocannabinoid system has recently been implicated in the regulation of various pathophysiological processes of the skin that include immune competence and/or tolerance of keratinocytes, the disruption of which might promote the development of skin diseases. Recent evidence showed that CB1 in keratinocytes limits the secretion of proinflammatory chemokines, suggesting that this receptor might also regulate T cell dependent inflammatory diseases of the skin. In this article, we sought to investigate the cytokine profile of IFN-gamma-activated keratinocytes, and found that CB1 activation by AEA suppressed production and release of signature TH1- and TH17-polarizing cytokines, IL-12 and IL-23, respectively. We also set up cocultures between a conditioned medium of treated keratinocytes and naive T cells to disclose the molecular details that regulate the activation of highly proinflammatory TH1 and TH17 cells. AEA-treated keratinocytes showed reduced an induction of IFN-gamma producing TH1 and IL-17-producing TH17 cells, and these effects were reverted by pharmacological inhibition of CB1 Further analyses identified mammalian target of rapamycin as a proinflammatory signaling pathway regulated by CB1, able to promote either IL-12 and IL-23 release from keratinocytes or TH1 and TH17 polarization. Taken together, these findings demonstrate that AEA suppresses highly pathogenic T cell subsets through CB1-mediated mammalian target of rapamycin inhibition in human keratinocytes. Thus, it can be speculated that the latter pathway might be beneficial to the physiological function of the skin, and can be targeted toward inflammation-related skin diseases.

AB - CD4+ T cells are at the nexus of the innate and adaptive arms of the immune system. However, little is known about the evolutionary history of CD4+ T cells, and it is unclear whether their differentiation into specialized subsets is conserved in early vertebrates. In this study, we have created transgenic zebrafish with vibrantly labeled CD4+ cells allowing us to scrutinize the development and specialization of teleost CD4+ leukocytes in vivo. We provide further evidence that CD4+ macrophages have an ancient origin and had already emerged in bony fish. We demonstrate the utility of this zebrafish resource for interrogating the complex behavior of immune cells at cellular resolution by the imaging of intimate contacts between teleost CD4+ T cells and mononuclear phagocytes. Most importantly, we reveal the conserved subspecialization of teleost CD4+ T cells in vivo. We demonstrate that the ancient and specialized tissues of the gills contain a resident population of il-4/13b-expressing Th2 like cells, which do not coexpress il-4/13a Additionally, we identify a contrasting population of regulatory T cell-like cells resident in the zebrafish gut mucosa, in marked similarity to that found in the intestine of mammals. Finally, we show that, as in mammals, zebrafish CD4+ T cells will infiltrate melanoma tumors and obtain a phenotype consistent with a type 2 immune microenvironment. We anticipate that this unique resource will prove invaluable for future investigation of T cell function in biomedical research, the development of vaccination and health management in aquaculture, and for further research into the evolution of adaptive immunity. PMID- 27694496 TI - Antibody Binding to CD4 Induces Rac GTPase Activation and Alters T Cell Migration. AB - The use of nondepleting Abs specific for CD4 and CD8 is an effective strategy to tolerize CD4+ and CD8+ T cells in a tissue-specific manner. We reported that coreceptor therapy reverses diabetes in new onset NOD mice. A striking feature of coreceptor-induced remission is the purging of T cells from the pancreatic lymph nodes (PLN) and islets of NOD mice. Evidence indicates that Abs binding to the coreceptors promotes T cell egress from these tissues. The present study examined how coreceptor therapy affects the migration of CD4+ T cells residing in the PLN of NOD mice. Anti-CD4 Ab treatment resulted in an increased frequency of PLN but not splenic CD4+ T cells that exhibited a polarized morphology consistent with a migratory phenotype. Furthermore, PLN CD4+ T cells isolated from anti-CD4 versus control Ab-treated animals displayed increased in vitro chemotaxis to chemoattractants such as sphingosine-1-phosphate and CXCL12. Notably, the latter was dependent on activation of the small Rho GTPases Rac1 and Rac2. Rac1 and Rac2 activation was increased in Ab-bound CD4+ T cells from the PLN but not the spleen, and knockdown of Rac expression blocked the heightened reactivity of Ab bound PLN CD4+ T cells to CXCL12. Interestingly, Rac1 and Rac2 activation was independent of Rac guanine nucleotide exchange factors known to regulate T cell activity. Therefore, Ab binding to CD4 initiates a novel pathway that involves inflammation-dependent activation of Rac and establishment of altered T cell migratory properties.

AB - BACKGROUND: The management of small unruptured incidentally discovered intracranial aneurysms (SUIAs) is still controversial. The aim of this study is to assess the safety of a management protocol of SUIAs, where selected cases with SUIAs are observed and secured only if signs of instability (growth) are documented. METHODS: A prospective consecutive cohort of 292 patients (2006-2014) and 368 SUIAs (anterior circulation aneurysms (ACs) smaller than 7 mm and posterior circulation aneurysms smaller than 4 mm without previous subarachnoid haemorrhage) was observed (mean follow-up time of 3.2 years and 1177.6 aneurysm years). Factors associated with aneurysm growth were systematically reviewed from the literature. RESULTS: The aneurysm growth probability was 2.6+/-0.1% per year. The rate of unexpected aneurysm rupture before treatment was 0.24% per year (95% CI 0.17% to 2.40%). The calculated rate of aneurysm rupture after growth was 6.3% per aneurysm-year (95% CI 1% to 22%). Aneurysms located in the posterior circulation and aneurysms with lobulation were more likely to grow. Females or patients suffering hypertension were more likely to have an aneurysm growing. The probability of aneurysms growth increased with the size of the dome and was proportional to the number of aneurysms diagnosed in a patient. CONCLUSIONS: It is safe to observe patients diagnosed with SUIAs using periodic imaging. Intervention to secure the aneurysm should be performed after growth is observed.

AB - OBJECTIVE: To determine the feasibility of conducting a randomised controlled trial of a specialist physiotherapy intervention for functional motor symptoms (FMS). METHODS: A randomised feasibility study was conducted recruiting patients with a clinically established diagnosis of FMS from a tertiary neurology clinic in London, UK. Participants were randomised to the intervention or a treatment as usual control. Measures of feasibility and clinical outcome were collected and assessed at 6 months. RESULTS: 60 individuals were recruited over a 9-month period. Three withdrew, leaving 29 intervention and 28 controls participants in the final analysis. 32% of patients with FMS met the inclusion criteria, of which 90% enrolled. Acceptability of the intervention was high and there were no adverse events. At 6 months, 72% of the intervention group rated their symptoms as improved, compared to 18% in the control group. There was a moderate to large treatment effect across a range of outcomes, including three of eight Short Form 36 (SF36) domains (d=0.46-0.79). The SF36 Physical function was found to be a suitable primary outcome measure for a future trial; adjusted mean difference 19.8 (95% CI 10.2 to 29.5). The additional quality adjusted life years (QALY) with intervention was 0.08 (95% CI 0.03 to 0.13), the mean incremental cost per QALY gained was L12 087. CONCLUSIONS: This feasibility study demonstrated high rates of recruitment, retention and acceptability. Clinical effect size was moderate to large with high probability of being cost-effective. A randomised controlled trial is needed. TRIAL REGISTRATION NUMBER: NCT02275000; Results.

PMID- 27694501 TI - Advanced systemic mastocytosis: from molecular and genetic progress to clinical practice. AB - Systemic mastocytosis is a heterogeneous disease characterized by the accumulation of neoplastic mast cells in the bone marrow and other organ organs/tissues. Mutations in KIT, most frequently KIT D816V, are detected in over 80% of all systemic mastocytosis patients. While most systemic mastocytosis patients suffer from an indolent disease variant, some present with more aggressive variants, collectively called "advanced systemic mastocytosis", which include aggressive systemic mastocytosis, systemic mastocytosis with an associated hematologic, clonal non mast cell-lineage disease, and mast cell leukemia. Whereas patients with indolent systemic mastocytosis have a near normal life expectancy, patients with advanced systemic mastocytosis have a reduced life expectancy. Although cladribine and interferon-alpha are of benefit in a group of patients with advanced systemic mastocytosis, no curative therapy is available for these patients except possible allogeneic hematopoietic stem cell transplantation. Recent studies have also revealed additional somatic defects (apart from mutations in KIT) in a majority of patients with advanced systemic mastocytosis. These include TET2, SRSF2, ASXL1, RUNX1, JAK2, and/or RAS mutations, which may adversely impact prognosis and survival in particular systemic mastocytosis with an associated hematological neoplasm. In addition, several additional signaling molecules involved in the abnormal proliferation of mast cells in systemic mastocytosis have been identified. These advances have led to a better understanding of the biology of advanced systemic mastocytosis and to the development of new targeted treatment concepts. Herein, we review the biology and pathogenesis of advanced systemic mastocytosis, with a special focus on novel molecular findings as well as current and evolving therapeutic options.

PMID- 27694502 TI - Catching up with solid tumor oncology: what is the evidence for a prognostic role of programmed cell death-ligand 1/programmed cell death-1 expression in B-cell lymphomas? AB - Therapeutic strategies targeting the programmed cell death-ligand 1/programmed cell death-1 pathway have shown significant responses and good tolerability in solid malignancies. Although preclinical studies suggest that inhibiting programmed cell death-ligand 1/programmed cell death-1 interactions might also be highly effective in hematological malignancies, remarkably few clinical trials have been published. Determining patients who will benefit most from programmed cell death-ligand 1/programmed cell death-1-directed immunotherapy and whether programmed cell death-ligand 1/programmed cell death-1 are adequate prognostic markers becomes an increasingly important clinical question, especially as aberrant programmed cell death-ligand 1/programmed cell death-1 expression are key mediators of impaired anti-tumor immune responses in a range of B-cell lymphomas. Herein, we systematically review the published literature on the expression and prognostic value of programmed cell death-ligand 1/programmed cell death-1 in these patients and identify considerable differences in expression patterns, distribution and numbers of programmed cell death-ligand 1+/programmed cell death-1+cells, both between and within lymphoma subtypes, which is reflected in conflicting findings regarding the prognostic value of programmed cell death ligand 1+/programmed cell death-1+ cells. This can be partly explained by differences in methodologies (techniques, protocols, cutoff values) and definitions of positivity. Moreover, lymphomagenesis, disease progression, and prognosis appear to be determined not only by the presence, numbers and distribution of specific subtypes of T cells, but also by other cells and additional immune checkpoints. Collectively, our findings indicate that programmed cell death-ligand 1/programmed cell death-1 interactions play an essential role in B-cell lymphoma biology and are of clinical importance, but that the overall outcome is determined by additional components. To categorize the exact prognostic value of programmed cell death-ligand 1/programmed cell death-1 expressing cells and cell types, efforts should be made to harmonize their assessment and interpretation, optimally within ongoing clinical immune checkpoint inhibitor trials, and to identify and validate novel high-throughput platforms.

AB - Current recommendations for applying the antiaggregation pheromone 3 methylcyclohex-2-en-1-one (MCH) to protect live trees from Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, infestation are to space individual passive releasers (MCH bubble capsules) on a 12- by 12-m grid throughout areas to be protected. Previous field studies and a theoretical study using a puff dispersion model to predict pheromone concentrations have shown that releasers emitting higher rates of MCH spaced farther apart may be as effective as the established standard treatment. During 2012 and 2013, we tested higher release rates of MCH at correspondingly wider spacings to keep the total amount of MCH released per unit area equal in all treatments. In 2012 near Challis, ID, treatments included the established standard release rate and spacing, four and six times the standard release rate at correspondingly wider spacings, and an untreated control. In 2013 near Ketchum, ID, treatments included the established standard release rate and spacing, five and seven times the standard release rate at correspondingly wider spacings, and an untreated control. Results from both years indicated that all MCH treatments were equally effective in reducing Douglas-fir beetle infestation. Using higher release rate formulations at wider spacings will reduce labor costs of installing MCH treatments, and, in cases where it is necessary, retrieving the releasers as well. In addition to reducing labor costs, the revised treatment protocol may increase the feasibility of treating areas that currently may not be possible due to treatment costs.

PMID- 27694509 TI - Radiological Decision Aid to determine suitability for medial unicompartmental knee arthroplasty: development and preliminary validation. AB - AIMS: An evidence-based radiographic Decision Aid for meniscal-bearing unicompartmental knee arthroplasty (UKA) has been developed and this study investigates its performance at an independent centre. PATIENTS AND METHODS: Pre operative radiographs, including stress views, from a consecutive cohort of 550 knees undergoing arthroplasty (UKA or total knee arthroplasty; TKA) by a single surgeon were assessed. Suitability for UKA was determined using the Decision Aid, with the assessor blinded to treatment received, and compared with actual treatment received, which was determined by an experienced UKA surgeon based on history, examination, radiographic assessment including stress radiographs, and intra-operative assessment in line with the recommended indications as described in the literature. RESULTS: The sensitivity and specificity of the Decision Aid was 92% and 88%, respectively. Excluding knees where a clear pre-operative plan was made to perform TKA, i.e. patient request, the sensitivity was 93% and specificity 96%. The false-positive rate was low (2.4%) with all affected patients readily identifiable during joint inspection at surgery. In patients meeting Decision Aid criteria and receiving UKA, the five-year survival was 99% (95% confidence intervals (CI) 97 to 100). The false negatives (3.5%), who received UKA but did not meet the criteria, had significantly worse functional outcomes (flexion p < 0.001, American Knee Society Score - Functional p < 0.001, University of California Los Angeles score p = 0.04), and lower implant survival of 93.1% (95% CI 77.6 to 100). CONCLUSION: The radiographic Decision Aid safely and reliably identifies appropriate patients for meniscal-bearing UKA and achieves good results in this population. The widespread use of the Decision Aid should improve the results of UKA. Cite this article: Bone Joint J 2016;98-B(10 Suppl B):3-10. PMID- 27694510 TI - Does location of patellofemoral chondral lesion influence outcome after Oxford medial compartmental knee arthroplasty? AB - AIMS: Medial unicompartmental knee arthroplasty (UKA) is associated with successful outcomes in carefully selected patient cohorts. We hypothesised that severity and location of patellofemoral cartilage lesions significantly influences functional outcome after Oxford medial compartmental knee arthroplasty. PATIENTS AND METHODS: We reviewed 100 consecutive UKAs at minimum eight-year follow-up (96 to 132). A single surgeon performed all procedures. Patients were selected based on clinical and plain radiographic assessment. All patients had end-stage medial compartment osteoarthritis (OA) with sparing of the lateral compartment and intact anterior cruciate ligaments. None of the patients had end-stage patellofemoral OA, but patients with anterior knee pain or partial thickness chondral loss were not excluded. There were 57 male and 43 female patients. The mean age at surgery was 69 years (41 to 82). At surgery the joint was carefully inspected for patellofemoral chondral loss and this was documented based on severity of cartilage loss (0 to 4 Outerbridge grading) and topographic location (medial, lateral, central, and superior or inferior). Functional scores collected included Oxford Knee Score (OKS), patient satisfaction scale and University College Hospital (UCH) knee score. Intraclass correlation was used to compare chondral damage to outcomes. RESULTS: All patients documented significant improvement in pain and improved functional scores at mid-term follow-up. There were four revisions (mean 2.9 years, 2 to 4; standard deviation (sd) 0.9) in this cohort, three for tibial loosening and one for femoral loosening. There was one infection that was treated with debridement and insert exchange. The mean OKS improved from 23.2 (sd 7.1) to 39.1 (sd 6.9); p < 0.001. The cohort with central and lateral grade 3 patellofemoral OA documented lower mean satisfaction with pain (90, sd 11.8) and function (87.5, sd 10.3) on the patient satisfaction scale. On the UCH scale, patients reported significantly decreased mean overall scores (7.3, sd 1.2 vs 9, sd 2.3) as well as stair climb task (3.5, sd 0.3 vs 5, sd 0.1) when cartilage lesions were located centrally or laterally on the PFJ. Patients with medial chondral PFJ lesions behave similar to patients with no chondral lesions. CONCLUSION: Topographical location and severity of cartilage damage of the patella can significantly influence function after successful Oxford medial UKA. Surgeons should factor this in when making their operative decision, and undertake to counsel patients appropriately. Cite this article: Bone Joint J 2016;98-B(10 Suppl B):11-15. PMID- 27694511 TI - Gait comparison of unicompartmental and total knee arthroplasties with healthy controls. AB - AIMS: To compare the gait of unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) patients with healthy controls, using a machine-learning approach. PATIENTS AND METHODS: 145 participants (121 healthy controls, 12 patients with cruciate-retaining TKA, and 12 with mobile-bearing medial UKA) were recruited. The TKA and UKA patients were a minimum of 12 months post-operative, and matched for pattern and severity of arthrosis, age, and body mass index. Participants walked on an instrumented treadmill until their maximum walking speed was reached. Temporospatial gait parameters, and vertical ground reaction force data, were captured at each speed. Oxford knee scores (OKS) were also collected. An ensemble of trees algorithm was used to analyse the data: 27 gait variables were used to train classification trees for each speed, with a binary output prediction of whether these variables were derived from a UKA or TKA patient. Healthy control gait data was then tested by the decision trees at each speed and a final classification (UKA or TKA) reached for each subject in a majority voting manner over all gait cycles and speeds. Top walking speed was also recorded. RESULTS: 92% of the healthy controls were classified by the decision tree as a UKA, 5% as a TKA, and 3% were unclassified. There was no significant difference in OKS between the UKA and TKA patients (p = 0.077). Top walking speed in TKA patients (1.6 m/s; 1.3 to 2.1) was significantly lower than that of both the UKA group (2.2 m/s; 1.8 to 2.7) and healthy controls (2.2 m/s; 1.5 to 2.7; p < 0.001). CONCLUSION: UKA results in a more physiological gait compared with TKA, and a higher top walking speed. This difference in function was not detected by the OKS.

PMID- 27694512 TI - A survival analysis of 1084 knees of the Oxford unicompartmental knee arthroplasty: a comparison between consultant and trainee surgeons. AB - AIMS: The aim of this to study was to compare the previously unreported long-term survival outcome of the Oxford medial unicompartmental knee arthroplasty (UKA) performed by trainee surgeons and consultants. PATIENTS AND METHODS: We therefore identified a previously unreported cohort of 1084 knees in 947 patients who had a UKA inserted for anteromedial knee arthritis by consultants and surgeons in training, at a tertiary arthroplasty centre and performed survival analysis on the group with revision as the endpoint. RESULTS: The ten-year cumulative survival rate for revision or exchange of any part of the prosthetic components was 93.2% (95% confidence interval (CI) 86.1 to 100, number at risk 45). Consultant surgeons had a nine-year cumulative survival rate of 93.9% (95% CI 90.2 to 97.6, number at risk 16). Trainee surgeons had a cumulative nine-year survival rate of 93.0% (95% CI 90.3 to 95.7, number at risk 35). Although there was no differences in implant survival between consultants and trainees (p = 0.30), there was a difference in failure pattern whereby all re-operations performed for bearing dislocation (n = 7), occurred in the trainee group. This accounted for 0.6% of the entire cohort and 15% of the re-operations. CONCLUSION: This is the largest single series of the Oxford UKA ever reported and demonstrates that good results can be achieved by a heterogeneous group of surgeons, including trainees, if performed within a high-volume centre with considerable experience with the procedure.

AB - AIMS: Since redesign of the Oxford phase III mobile-bearing unicompartmental knee arthroplasty (UKA) femoral component to a twin-peg design, there has not been a direct comparison to total knee arthroplasty (TKA). Thus, we explored differences between the two cohorts. PATIENTS AND METHODS: A total of 168 patients (201 knees) underwent medial UKA with the Oxford Partial Knee Twin-Peg. These patients were compared with a randomly selected group of 177 patients (189 knees) with primary Vanguard TKA. Patient demographics, Knee Society (KS) scores and range of movement (ROM) were compared between the two cohorts. Additionally, revision, re operation and manipulation under anaesthesia rates were analysed. RESULTS: The mean follow-up for UKA and TKA groups was 5.4 and 5.5 years, respectively. Six TKA (3.2%) versus three UKAs (1.5%) were revised which was not significant (p = 0.269). Manipulation was more frequent after TKA (16; 8.5%) versus none in the UKA group (p < 0.001). UKA patients had higher post-operative KS function scores versus TKA patients (78 versus 66, p < 0.001) with a trend toward greater improvement, but there was no difference in ROM and KS clinical improvement (p = 0.382 and 0.420, respectively). CONCLUSION: We found fewer manipulations, and higher functional outcomes for patients treated with medial mobile-bearing UKA compared with TKA. TKA had twice the revision rate as UKA although this did not reach statistical significance with the numbers available. Cite this article: Bone Joint J 2016;98-B(10 Suppl B):28-33. PMID- 27694514 TI - The results of Oxford unicompartmental knee arthroplasty in the United States: a mean ten-year survival analysis. AB - AIMS: Approved by the Food and Drug Administration in 2004, the Phase III Oxford Medial Partial Knee is used to treat anteromedial osteoarthritis (AMOA) in patients with an intact anterior cruciate ligament. This unicompartmental knee arthroplasty (UKA) is relatively new in the United States, and therefore long term American results are lacking. PATIENTS AND METHODS: This is a single surgeon, retrospective study based on prospectively collected data, analysing a consecutive series of primary UKAs using the Phase III mobile-bearing Oxford Knee and Phase III instrumentation. Between July 2004 and December 2006, the senior author (RHE) carried out a medial UKA in 173 patients (213 knees) for anteromedial osteoarthritis or avascular necrosis (AVN). A total of 95 patients were men and 78 were women. Their mean age at surgery was 67 years (38 to 89) and mean body mass index 29.87 kg/m2 (17 to 62). The mean follow-up was ten years (4 to 11). RESULTS: Survivorship of the Oxford UKA at ten years was 88%, using life table analysis. Implant survivorship at ten years was 95%. The most common cause for revision was the progression of osteoarthritis in the lateral compartment. The mean knee score element of the American Knee Society Score (AKSS) was 50 pre operatively and increased to 93 post-operatively. The mean AKSS function score was 56 pre-operatively rising to 78 post-operatively CONCLUSION: This ten-year follow-up study of the Oxford UKA undertaken in the United States shows good survivorship and excellent function in a wide selection of patients with AMOA and AVN.

PMID- 27694515 TI - Ten- to 15-year results of the Oxford Phase III mobile unicompartmental knee arthroplasty: a prospective study from a non-designer group. AB - AIMS: The interest in unicompartmental knee arthroplasty (UKA) for medial osteoarthritis has increased rapidly but the long-term follow-up of the Oxford UKAs has yet to be analysed in non-designer centres. We have examined our ten- to 15-year clinical and radiological follow-up data for the Oxford Phase III UKAs. PATIENTS AND METHODS: Between January 1999 and January 2005 a total of 138 consecutive Oxford Phase III arthroplasties were performed by a single surgeon in 129 patients for medial compartment osteoarthritis (71 right and 67 left knees, mean age 72.0 years (47 to 91), mean body mass index 28.2 (20.7 to 52.2)). Both clinical data and radiographs were prospectively recorded and obtained at intervals. Of the 129 patients, 32 patients (32 knees) died, ten patients (12 knees) were not able to take part in the final clinical and radiological assessment due to physical and mental conditions, but via telephone interview it was confirmed that none of these ten patients (12 knees) had a revision of the knee arthroplasty. One patient (two knees) was lost to follow-up. RESULTS: The mean follow-up was 11.7 years (10 to 15). A total of 11 knees (8%) were revised. The survival at 15 years with revision for any reason as the endpoint was 90.6% (95% confidence interval (CI) 85.2 to 96.0) and revision related to the prosthesis was 99.3% (95% CI 97.9 to 100). The mean total Knee Society Score was 47 (0 to 80) pre-operatively and 81 (30 to 100) at latest follow-up. The mean Oxford Knee Score was 19 (12 to 40) pre-operatively and 42 (28 to 55) at final follow-up. Radiolucency beneath the tibial component occurred in 22 of 81 prostheses (27.2%) without evidence of loosening. CONCLUSION: This study supports the use of UKA in medial compartment osteoarthritis with excellent long-term functional and radiological outcomes with an excellent 15-year survival rate.

AB - BACKGROUND: Of our 1400 exome-studied patients, 67% originate from consanguineous families. ~80% suffer from variable degree of intellectual disability (ID). The search for disease causing genes using homozygosity mapping was progressing slowly until 2010, then markedly accelerated by the introduction of exome analysis. OBJECTIVES: To identify the disease causing mutation(s) in three patients from two unrelated families who suffered from global developmental delay, severe ID and drug-responsive seizure disorder. METHODS: Exome analysis was performed in DNA of the three patients. The identified PIGC variants were generated and transfected into PIGC-defective mouse cells and the restoration of the surface expression of mouse CD90, CD48 and FLAER was assessed using flow cytometry. The expression of these proteins was also studied on the surface of patients' leucocytes. RESULTS: Three PIGC mutations were identified; homozygous p.L189W in one family and compound heterozygosity for p.L212P/p.R21X variants in another. PIGC participates in the biosynthesis of the glycosylphosphatidylinositol (GPI) anchor which tethers proteins to plasma membrane. In cells lacking PIGC protein, which were transfected with each of the PIGC variants, we detected a clear reduction of surface expression of GPI anchored proteins. Furthermore, analyses of patients' leucocytes showed significant and constant decrease of CD16 surface expression in granulocytes, and moderate decrease of CD14, CD55, CD59 and FLAER levels. CONCLUSIONS: PIGC joins the list of genes in which mutations result in defective biosynthesis of GPI anchoring, manifesting by global developmental delay and seizure disorder. The lack of specific biomarker dictates exome sequencing as the diagnostic procedure of choice in similar patients. PMID- 27694524 TI - Phytochelatin Synthesis Promotes Leaf Zn Accumulation of Arabidopsis thaliana Plants Grown in Soil with Adequate Zn Supply and is Essential for Survival on Zn Contaminated Soil. AB - Phytochelatin (PC) synthesis is essential for the detoxification of non-essential metals such as cadmium (Cd). In vitro experiments with Arabidopsis thaliana seedlings had indicated a contribution to zinc (Zn) tolerance as well. We addressed the physiological role of PC synthesis in Zn homeostasis of plants under more natural conditions. Growth responses, PC accumulation and leaf ionomes of wild-type and AtPCS1 mutant plants cultivated in different soils representing adequate Zn supply, Zn deficiency and Zn excess were analyzed. Growth on Zn contaminated soil triggers PC synthesis and is strongly impaired in PC-deficient mutants. In fact, the contribution of AtPCS1 to tolerating Zn excess is comparable with that of the major Zn tolerance factor MTP1. For plants supplied with a normal level of Zn, a significant reduction in leaf Zn accumulation of AtPCS1 mutants was detected. In contrast, AtPCS1 mutants grown under Zn-limited conditions showed wild-type levels of Zn accumulation, suggesting the operation of distinct Zn translocation pathways. Contrasting phenotypes of the tested AtPCS1 mutant alleles upon growth in Zn- or Cd-contaminated soil indicated differential activation of PC synthesis by these metals. Experiments with truncated versions identified a part of the AtPCS1 protein required for the activation by Zn but not by Cd.

AB - Plants produce many bioactive, specialized metabolites to defend themselves when facing various stress situations. Their biosynthesis is directed by a tightly controlled regulatory circuit that is elicited by phytohormones such as jasmonate (JA). The basic helix-loop-helix (bHLH) transcription factors (TFs) bHLH iridoid synthesis 1 (BIS1) and Triterpene Saponin Activating Regulator (TSAR) 1 and 2, from Catharanthus roseus and Medicago truncatula, respectively, all belong to clade IVa of the bHLH protein family and activate distinct terpenoid pathways, thereby mediating monoterpenoid indole alkaloid (MIA) and triterpene saponin (TS) accumulation, respectively, in these two species. In this study, we report that promoters of the genes encoding the enzymes involved in the specific terpenoid pathway of one of these species can be transactivated by the orthologous bHLH factor from the other species through recognition of the same cis-regulatory elements. Accordingly, ectopic expression of CrBIS1 in M. truncatula hairy roots up-regulated the expression of all genes required for soyasaponin production, resulting in strongly increased levels of soyasaponins in the transformed roots. Likewise, transient expression of MtTSAR1 and MtTSAR2 in C. roseus petals led to up-regulation of the genes involved in the iridoid branch of the MIA pathway. Together, our data illustrate the functional similarity of these JA-inducible TFs and indicate that recruitment of defined cis-regulatory elements constitutes an important aspect of the evolution of conserved regulatory modules for the activation of species-specific terpenoid biosynthesis pathways by common signals such as the JA phytohormones. PMID- 27694526 TI - Motor unit number estimates and neuromuscular transmission in the tibialis anterior of master athletes: evidence that athletic older people are not spared from age-related motor unit remodeling. AB - Muscle motor unit numbers decrease markedly in old age, while remaining motor units are enlarged and can have reduced neuromuscular junction transmission stability. However, it is possible that regular intense physical activity throughout life can attenuate this remodeling. The aim of this study was to compare the number, size, and neuromuscular junction transmission stability of tibialis anterior (TA) motor units in healthy young and older men with those of exceptionally active master runners. The distribution of motor unit potential (MUP) size was determined from intramuscular electromyographic signals recorded in healthy male Young (mean +/- SD, 26 +/- 5 years), Old (71 +/- 4 years) and Master Athletes (69 +/- 3 years). Relative differences between groups in numbers of motor units was assessed using two methods, one comparing MUP size and muscle cross-sectional area (CSA) determined with MRI, the other comparing surface recorded MUPs with maximal compound muscle action potentials and commonly known as a "motor unit number estimate (MUNE)". Near fiber (NF) jiggle was measured to assess neuromuscular junction transmission stability. TA CSA did not differ between groups. MUNE values for the Old and Master Athletes were 45% and 40%, respectively, of the Young. Intramuscular MUPs of Old and Master Athletes were 43% and 56% larger than Young. NF jiggle was slightly higher in the Master Athletes, with no difference between Young and Old. These results show substantial and similar motor unit loss and remodeling in Master Athletes and Old individuals compared with Young, which suggests that lifelong training does not attenuate the age-related loss of motor units. PMID- 27694527 TI - Videomicroscopy as a tool for investigation of the microcirculation in the newborn. AB - The perinatal period remains a time of significant risk of death or disability. Increasing evidence suggests that this depends on microcirculatory behavior. Sidestream dark-field orthogonal polarized light videomicroscopy (OPS) has emerged as a useful assessment of adult microcirculation but the values derived are not delineated for the newborn. We aimed to define these parameters in well term newborn infants. Demographic details were collected prospectively on 42 healthy term neonates (n = 20 females, n = 22 males). OPS videomicroscopy (Microscan) was used to view ear conch skin microcirculation at 6, 24, and 72 h of age. Stored video was analyzed by a masked observer using proprietary software. There were no significant differences between the sexes for any structural parameters at any time point. There was a significant increase over time in small vessel perfusion in female infants only (P = 0.009). A number of 6- and 72-h measurements were significantly correlated, but differed from the 24-h values. These observations confirm the utility of the ear conch for neonatal microvascular videomicroscopy. They provide a baseline for studies into the use of OPS videomicroscopy in infants. The changes observed are comparable with previous studies of term infants using these and other microvascular techniques. It is recommended that studies for examining the mature neonatal microvascular structure be delayed until 72 h of life, but studies of the physiology of cardiovascular transition should include the 24-h time point after delivery. PMID- 27694528 TI - Plasma acylcarnitine profiling indicates increased fatty acid oxidation relative to tricarboxylic acid cycle capacity in young, healthy low birth weight men. AB - We hypothesized that an increased, incomplete fatty acid beta-oxidation in mitochondria could be part of the metabolic events leading to insulin resistance and thereby an increased type 2 diabetes risk in low birth weight (LBW) compared with normal birth weight (NBW) individuals. Therefore, we measured fasting plasma levels of 45 acylcarnitine species in 18 LBW and 25 NBW men after an isocaloric control diet and a 5-day high-fat, high-calorie diet. We demonstrated that LBW men had higher C2 and C4-OH levels after the control diet compared with NBW men, indicating an increased fatty acid beta-oxidation relative to the tricarboxylic acid cycle flux. Also, they had higher C6-DC, C10-OH/C8-DC, and total hydroxyl /dicarboxyl-acylcarnitine levels, which may suggest an increased fatty acid omega oxidation in the liver. Furthermore, LBW and NBW men decreased several acylcarnitine levels in response to overfeeding, which is likely a result of an upregulation of fatty acid oxidation due to the dietary challenge. Moreover, C10 OH/C8-DC and total hydroxyl-/dicarboxyl-acylcarnitine levels tended to be negatively associated with the serum insulin level, and the total hydroxyl /dicarboxyl-acylcarnitine level additionally tended to be negatively associated with the hepatic insulin resistance index. This indicates that an increased fatty acid omega-oxidation could be a compensatory mechanism to prevent an accumulation of lipid species that impair insulin signaling. PMID- 27694529 TI - Reduced mitochondrial mass and function add to age-related susceptibility toward diet-induced fatty liver in C57BL/6J mice. AB - Nonalcoholic fatty liver disease (NAFLD) is a major health burden in the aging society with an urging medical need for a better understanding of the underlying mechanisms. Mitochondrial fatty acid oxidation and mitochondrial-derived reactive oxygen species (ROS) are considered critical in the development of hepatic steatosis, the hallmark of NAFLD. Our study addressed in C57BL/6J mice the effect of high fat diet feeding and age on liver mitochondria at an early stage of NAFLD development. We therefore analyzed functional characteristics of hepatic mitochondria and associated alterations in the mitochondrial proteome in response to high fat feeding in adolescent, young adult, and middle-aged mice. Susceptibility to diet-induced obesity increased with age. Young adult and middle aged mice developed fatty liver, but not adolescent mice. Fat accumulation was negatively correlated with an age-related reduction in mitochondrial mass and aggravated by a reduced capacity of fatty acid oxidation in high fat-fed mice. Irrespective of age, high fat diet increased ROS production in hepatic mitochondria associated with a balanced nuclear factor erythroid-derived 2 like 2 (NFE2L2) dependent antioxidative response, most likely triggered by reduced tethering of NFE2L2 to mitochondrial phosphoglycerate mutase 5. Age indirectly influenced mitochondrial function by reducing mitochondrial mass, thus exacerbating diet-induced fat accumulation. Therefore, consideration of age in metabolic studies must be emphasized. PMID- 27694530 TI - AT-RvD1 combined with DEX is highly effective in treating TNF-alpha-mediated disruption of the salivary gland epithelium. AB - Sjogren's syndrome (SS) is an autoimmune disorder characterized by chronic inflammation and destruction of salivary and lacrimal glands leading to dry mouth and dry eyes, respectively. Currently, the etiology of SS is unknown and the current therapies have no permanent benefit; therefore, new approaches are necessary to effectively treat this condition. Resolvins are highly potent endogenous lipid mediators that are synthesized during the resolution of inflammation to restore tissue homeostasis. Previous studies indicate that the resolvin family member, RvD1, binds to the ALX/FPR2 receptor to block inflammatory signals caused by tumor necrosis factor-alpha (TNF-alpha) in the salivary epithelium. More recently, the corticosteroid, dexamethasone (DEX), was shown to be effective in reducing salivary gland inflammation. However, DEX, as with other corticosteroids, elicits adverse secondary effects that could be ameliorated when used in smaller doses. Therefore, we investigated whether the more stable aspirin-triggered (AT) epimer, AT-RvD1, combined with reduced doses of DEX is effective in treating TNF-alpha-mediated disruption of polarized rat parotid gland (Par-C10) epithelial cell clusters. Our results indicate that AT RvD1 and DEX individually reduced TNF-alpha-mediated alteration in the salivary epithelium (i.e, maintained cell cluster formation, increased lumen size, reduced apoptosis, and preserved cell survival signaling responses) as compared to untreated cells. Furthermore, AT-RvD1 combined with a reduced dose of DEX produced stronger responses (i.e., robust salivary cell cluster formation, larger lumen sizes, further reduced apoptosis, and sustained survival signaling responses) as compared to those observed with individual treatments. These studies demonstrate that AT-RvD1 combined with DEX is highly effective in treating TNF-alpha-mediated disruption of salivary gland epithelium. PMID- 27694531 TI - Anodal transcranial direct current stimulation over right dorsolateral prefrontal cortex alters decision making during approach-avoidance conflict. AB - Approach-avoidance conflict (AAC) refers to situations associated with both rewarding and threatening outcomes. The AAC task was developed to measure AAC decision-making. Approach behavior during this task has been linked to self reported anxiety sensitivity and has elicited anterior cingulate, insula, caudate and right dorsolateral prefrontal cortex (dlPFC) activity, with right lateral PFC tracking the extent of approach behavior. Guided by these results, we used excitatory transcranial direct current stimulation (tDCS) to demonstrate the causal involvement of right dlPFC in AAC decision-making. Participants received anodal tDCS at 1.5mA over either left or right dlPFC or sham stimulation, while performing the AAC task and a control short-term memory task. Analyses of variance (ANOVA) revealed that for individuals with high anxiety sensitivity excitatory right (but not left or sham) dlPFC stimulation elicited measurable decreases in approach behavior during conflict. Excitatory left (but not right or sham) dlPFC simulation improved performance on the control task. These results support a possible asymmetry between the contributions of right and left dlPFC to AAC resolution during emotional decision-making. Increased activity in right dlPFC may contribute to anxiety-related symptoms and, as such, serve as a neurobehavioral target of anxiolytic treatments aiming to decrease avoidance behavior. PMID- 27694532 TI - Heart rate at admission is a predictor of in-hospital mortality in patients with acute coronary syndromes: Results from 58 European hospitals: The European Hospital Benchmarking by Outcomes in acute coronary syndrome Processes study. AB - AIMS: The purpose of this study was to investigate the relationship between heart rate at admission and in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation acute coronary syndrome (NSTE-ACS). METHODS: Consecutive ACS patients admitted in 2008-2010 across 58 hospitals in six participant countries of the European Hospital Benchmarking by Outcomes in ACS Processes (EURHOBOP) project (Finland, France, Germany, Greece, Portugal and Spain). Cardiogenic shock patients were excluded. Associations between heart rate at admission in categories of 10 beats per min (bpm) and in-hospital mortality were estimated by logistic regression in crude models and adjusting for age, sex, obesity, smoking, hypertension, diabetes, known heart failure, renal failure, previous stroke and ischaemic heart disease. In total 10,374 patients were included. RESULTS: In both STEMI and NSTE-ACS patients, a U-shaped relationship between admission heart rate and in-hospital mortality was found. The lowest risk was observed for heart rates between 70-79 bpm in STEMI and 60-69 bpm in NSTE-ACS; risk of mortality progressively increased with lower or higher heart rates. In multivariable models, the relationship persisted but was significant only for heart rates >80 bpm. A similar relationship was present in both patients with or without diabetes, above or below age 75 years, and irrespective of the presence of atrial fibrillation or use of beta-blockers. CONCLUSION: Heart rate at admission is significantly associated with in-hospital mortality in patients with both STEMI and NSTE-ACS. ACS patients with admission heart rate above 80 bpm are at highest risk of in hospital mortality. PMID- 27694533 TI - Pokemon GO: Imaginary Creatures, Tangible Risks. PMID- 27694534 TI - Pain Among Community-Dwelling Older Adults with Dementia: Factors Associated with Undertreatment. AB - Objective: To identify factors associated with no analgesic treatment in community-dwelling older adults with mild-to-moderate dementia and moderate-to severe pain. Design: Secondary analysis of a randomized controlled trial. Setting: Michael E. DeBakey Veterans Affairs Medical Center. Subjects: Two hundred and two older adults (mean age = 79.27 years). Methods: Guided by the Behavioral Model of Health Service Utilization, participants completed questionnaires regarding predisposing (age, gender, race, educational level, care partner relationship), enabling (income), and need (pain interference, depressive symptoms, cognitive functioning) characteristics. Results: Hierarchical logistic regression analyses revealed that participants with greater income (odds ratio [OR] = 0.79, 95% confidence interval [CI] = 0.63-0.99) and greater pain interference (OR = 0.79, 95% CI = 0.63-0.99) were less likely to have no analgesic treatment. We also examined whether other factors such as depressive symptoms influenced the relationship between pain interference and pain treatment. Those with less pain interference were more likely to have no analgesic treatment (OR = 1.04, 95% CI = 1.01-1.08), but only if they had lower levels of depressive symptoms (b = -0.52, P = 0.005). Conclusion: The initiation of analgesic trials is complicated for individuals with dementia and comorbid pain and depressive symptomology. Future research should focus on identifying the most effective assessment and treatment procedures to best direct clinical care for this population. PMID- 27694535 TI - Sinus Penetration of a Pulsating Device Versus the Classic Squeeze Bottle in Cadavers Undergoing Sinus Surgery. AB - OBJECTIVES: Nasal irrigation is standard in the management of chronic rhinosinusitis both before and after surgical intervention. Numerous irrigation devices are commercially available. The aim of this study was to compare the efficacy of a handheld pulse irrigation device against the gold standard manual squeeze bottle after endoscopic sinus surgery (ESS). METHODS: Five cadaveric specimens were prepared with video visualization ports into each sinus. Endoscopic sinus surgery was performed on each cadaver from minimal to maximal dissection. Sinuses were irrigated with fluorescein solution using both devices following each dissection. The irrigations were video recorded. A blinded independent observer scored each irrigation according to a defined scale. RESULTS: Comparison of the 2 devices using an intraclass correlation coefficient (ICC = 0.39) showed the 2 systems differed. Observation of individual sinuses showed the squeeze bottle consistently provided greater irrigation in the maxillary (P < .006), frontal (P < .0001), and sphenoid (P < .0001) sinuses. Pulse irrigation improved only in the maxillary sinus following ESS. CONCLUSION: The squeeze bottle consistently demonstrated superior irrigation in both native and operated conditions. Interestingly, saline penetration was not significantly improved after opening of the frontal and sphenoid sinuses. This is likely due to decreased backpressure in the nasal passage after opening the sinus cavities. PMID- 27694537 TI - Microangiopathic antiphospholipid antibody-associated syndrome in a pregnant lady. AB - We describe a gravid 37-year-old Chinese lady with known triple positive primary antiphospholipid syndrome with previous recurrent deep vein thrombosis and early spontaneous miscarriages. She was managed with low-molecular weight heparin, aspirin, hydroxychloroquine, prednisolone and monthly intravenous immunoglobulin. She presented with recurrent per-vaginal bleeding at 22 weeks of gestation and was found to have abruptio placentae. Anti-coagulation was held off. She subsequently delivered a stillborn at 24 weeks and anti-coagulation was restarted. Day 5 post-delivery, she developed HELLP, with hemolytic anaemia (Hb 10.1 g/dL, haptoglobin <30 g/L, LDH 2206 U/L), elevated transaminases (AST 1196 U/L, ALT 1130 U/L) and thrombocytopenia (platelet 28 * 10^9/L). There were also episodes of acute severe headache and abdominal pain assessed to be secondary to microvascular ischemia as CT did not reveal any thrombosis. Her blood pressure hovered persistently above systolic 180 mmHg, and required at least three anti hypertensives. These were coupled with a new onset proteinuria of 2 to 3 g/day. There was no evidence of disseminated intravascular coagulation. She was assessed to have microangiopathic antiphospholipid syndrome and was started on plasmapheresis. On Day 10 post-partum, the patient complained of foul-smelling vaginal discharge and was found to have retained products of conception, which was immediately evacuated. Her course was followed by poly-microbial sepsis secondary to Enterococcus fecalis, Klebsiella Pneumoniae and Escherichia coli. The patient was further treated with imipenem and she completed eight exchanges of plasmapheresis followed by five days of intravenous immunoglobulins with good clinical and biochemical improvement. PMID- 27694536 TI - Laryngotracheal Stenosis in Children and Infants With Neurological Disorders: Management and Outcome. AB - INTRODUCTION: The goal of this retrospective study is to compare the management and outcome of surgical treatment of laryngotracheal stenosis in children and infants with and without an associated neurological disorder. PATIENTS AND METHOD: In a series of children operated on for subglottic stenosis (SGS), patients with an associated neurological disorder were identified. The following criteria were compared in children with and without neurological disease: grade of stenosis, age, technique (Crico-Tracheal Resection (CTR), Laryngo-Tracheo Plasty (LTP) in single and 2 stage, laser), analyzing duration, preoperative tracheostomy, decannulation rate, preoperative gastrostomy, and number of days in intensive care unit and in hospital. RESULTS: Two hundred twenty-three children were operated on for subglottic stenosis, of whom 68 (30.5%) had an associated neurological disorder. Some criteria were found to be statistically different between the 2 populations: mean age of 43 months in neurological population versus 13 months (P < .001). The distribution of the grades of SGS appeared similar in the 2 groups (P = .088), and the mean duration of stay in hospital and in ICU were not statistically different (respectively, P = .186 and P = .056) between the 2 groups; a 2-stage procedure was performed more frequently than 1 stage in the cases with associated neurological disorder-66.6% versus 36.5% (P = .013); the median duration of stenting was 20 days in those with neurological disease versus 12 (P = .021). Preoperative tracheotomy was noted in 75% of neurological patients versus 47.7% of the others (P < .001). The outcome was considered to be good (decannulation and no further treatment) following a single procedure in 82.4% of patients with neurological disorder, as against 86.5% of neurologically unimpaired subjects. The difference in outcome of surgery was not statistically different (P = .392) between the 2 groups. DISCUSSION AND CONCLUSION: It appears that subglottic stenosis in children with associated neurological disorder is not more severe than in neurologically normal patients. In three-quarters of the neurologically impaired cases, a preoperative tracheostomy was needed, but the rates of failure of postoperative decannulation are not statistically significant between the 2 groups. In our experience, 2 stage techniques are more often performed than single stage in this population in order to allow airway safety, for example after feeding. If properly managed, the final results are similar in the 2 populations. PMID- 27694538 TI - Tumours and the heart: common risk factors, chemotherapy, and radiation.

AB - BACKGROUND: Heart failure is a major growing problem and affects not only patients but also their families and community networks and reduces the functional capacity of patients and impairs their social life. RESEARCH QUESTIONS: This study was conducted to investigate relationship between illness related worries and social dignity in patients with heart failure. DESIGN: The study had a descriptive-analytic design, and data collection was carried out by means of two specific questionnaires. Participants and context: A total of 130 inpatients from cardiac wards in hospitals affiliated with Tehran and Shahid Beheshti University of Medical Sciences participated. Ethical consideration: This study was approved by the Research Committee of Shahid Beheshti University of Medical Sciences. RESULTS: The highest mean score of illness-related worries was attributed to the dimension of patient's worry of physical-mental complications, and the least mean score was related to the dimension of the worry about the future of disease. The highest mean score of social dignity was associated with the dimension of social communication and support, and the least is attributed to the dimension of burden to others (economic). Pearson's statistical test showed a significant correlation (r = 0.455, p < 0.05) between the score of illness related worries and social dignity. DISCUSSION: As the result of this study showed that reducing illness-related worries in patients with heart failure can improve their social dignity, using strategies to decrease worries and promote social dignity in these patients is recommended. CONCLUSION: This study affirms the importance of careful evaluation of individual patients to determine their needs related to dignity. We hope these results will help to promote actions by patient-care staff that honor and support patient dignity, resulting in benefits to patients and developing the quality of care based on human rights. PMID- 27694545 TI - Potential vectors of equine arboviruses in the UK. AB - There is growing concern about the increasing risk of disease outbreaks caused by arthropod-borne viruses (arboviruses) in both human beings and animals. There are several mosquito-borne viral diseases that cause varying levels of morbidity and mortality in horses and that can have substantial welfare and economic ramifications. While none has been recorded in the UK, vector species for some of these viruses are present, suggesting that UK equines may be at risk. The authors undertook, therefore, the first study of mosquito species on equine premises in the UK. Mosquito magnet traps and red-box traps were used to sample adults, and larvae were collected from water sources such as tyres, buckets, ditches and pools. Several species that are known to be capable of transmitting important equine infectious arboviruses were trapped. The most abundant, with a maximum catch of 173 in 72 hours, was Ochlerotatus detritus, a competent vector of some flaviviruses; the highest densities were found near saltmarsh habitats. The most widespread species, recorded at >75 per cent of sites, was Culiseta annulata. This study demonstrates that potential mosquito vectors of arboviruses, including those known to be capable of infecting horses, are present and may be abundant on equine premises in the UK. PMID- 27694548 TI - Ethical competence: An integrative review. AB - BACKGROUND: Ethics, being a fundamental component of nursing practice, must be integrated in the nursing education curriculum. Even though different bodies are promoting ethics and nursing researchers have already carried out work as regards this concept, it still remains difficult to clearly identify the components of this competence. OBJECTIVE: This integrative review intends to clarify this point in addition to better defining ethical competence in the context of nursing practice. METHOD: An integrative review was carried out, for the 2009-2014 period, in the CINAHL, MEDLINE, and EMBASE databases and in the journal Nursing Ethics. The keywords nursing ethics or ethical competence were used in order to make sure to widely encompass the concept of "ethical competence" in the case of a university curriculum in nursing. In the end, 89 articles were selected. Ethical consideration: We have respected the ethical requirements required regarding the sources and authorship. There is no conflict of interest in this literature review. RESULTS: Ethical sensitivity, Ethical knowledge, Ethical reflection, Ethical decision-making, Ethical action, and Ethical behavior are the most frequently used terms with regard to ethical competence in nursing. They were then defined so as to better ascertain the possible components of ethical competence in nursing. CONCLUSION: Even though ethical competence represents a sine qua non competence in nursing practice, no consensus can be found in literature with respect to its definition. The identification of its components and their relationships resulting from this integrative review adds to the clarification of its definition. It paves the way for other studies that will contribute to a better understanding of its development, especially among nursing students and practicing nurses, as well as the factors that may exert an influence. More adapted education strategies can thus be put forward to support its development. PMID- 27694549 TI - Impacts of Socratic questioning on moral reasoning of nursing students. AB - BACKGROUND: Nurses are often faced with complex situations that made them to make ethical decisions; and to make such decisions, they need to possess the power of moral reasoning. Studies in Iran show that the majority of nursing students lack proper ethical development. Socratic teaching is a student-centered method which is strongly opposed to the lecturing method. OBJECTIVES: This study was conducted to evaluate the impacts of Socratic questioning on the moral reasoning of the nursing students. RESEARCH DESIGN: In a quasi-experimental study, Crisham's Nursing Dilemma Test was used to evaluate the results of three groups before, immediately after, and 2 months after intervention. The data were analyzed using the SPSS statistical software (v 15). Participants and research context: Through random allocation, 103 nursing students were divided into three groups. In experiment group 1 (37 students), intervention consisted of Socratic questioning based sessions on ethics and how to deal with moral dilemmas; experiment group 2 (33 students) attended a 4-h workshop; and the control group (33 students) was not subject to any interventions. Signed informed consent forms: This research was approved by the Ethics Committee of the University. All the participants signed written informed consents. FINDINGS: There were significant differences between experiment group 1 and experiment group 2's pre-test and post-test scores on moral reasoning (p <= 0.001, p <= 0.001), nursing principled thinking (p <= 0.001, p <= 0.001), and practical considerations (p <= 0.001, p <= 0.031). DISCUSSION: Both the teaching approaches improved the subjects' moral reasoning; however, Socratic questioning proved more effective than lecturing. Compared to other similar studies in Iran and other countries, the students had inadequate moral reasoning competence. CONCLUSION: This study confirms the need for the development of an efficient course on ethics in the nursing curriculum. Also, it appears that Socratic questioning is an effective method to teach nursing ethics and develop nursing students' competence of moral reasoning. PMID- 27694550 TI - New Fathers' Perinatal Depression and Anxiety-Treatment Options: An Integrative Review. AB - More than 10% of fathers experience depression and anxiety during the perinatal period, but paternal perinatal depression (PPND) and anxiety have received less attention than maternal perinatal mental health problems. Few mainstream treatment options are available for men with PPND and anxiety. The aim of this literature review was to summarize the current understanding of PPND and the treatment programs specifically designed for fathers with perinatal depression. Eight electronic databases were searched using a predefined strategy, and reference lists were also hand searched. PPND and anxiety were identified to have a negative impact on family relationships, as well as the health of mothers and children. Evidence suggests a lack of support and tailored treatment options for men having trouble adjusting to the transition to fatherhood. Of the limited options available, cognitive behavioral therapy, group work, and blended delivery programs, including e-support approaches appear to be most effective in helping fathers with perinatal depression and anxiety. The review findings have important implications for the understanding of PPND and anxiety. Future research is needed to address the adoption of father-inclusive and father-specific models of care to encourage fathers' help-seeking behavior. Inclusion of male-specific requirements into support and treatment options can improve the ability of services to engage new fathers. Psychotherapeutic intervention could assist to address the cognitive differences and dissonance for men adjusting to the role of father, including male identity and role expectations. PMID- 27694551 TI - Impact of Marital Status on Tumor Stage at Diagnosis and on Survival in Male Breast Cancer. AB - The effect of marital status (MS) on survival varies according to cancer type and gender. There has been no report on the impact of MS on survival in male breast cancer (MBC). This study aims to determine the influence of MS on tumor stage at diagnosis and survival in MBC. Men with MBC >=18 years of age in the SEER database from 1990 to 2011 were included in the study. MS was classified as married and unmarried (including single, divorced, separated, widowed). Kaplan Meier method was used to estimate the 5-year cancer-specific survival. Multivariate regression analyses were done to determine the effect of MS on presence of Stage IV disease at diagnosis and on cancer-specific mortality. The study included 3,761 men; 2,647 (70.4%) were married. Unmarried men were more often diagnosed with Stage IV MBC compared with married (10.7% vs. 5.5%, p < .001). Unmarried men (compared with married) were significantly less likely to undergo surgery (92.4% vs. 96.7%, p < .001). Overall unmarried males with Stages II, III, and IV MBC have significantly worse 5-year cancer-specific survival compared with married. On multivariate analysis, being unmarried was associated with increased hazard of death (HR = 1.43, p < .001) and increased likelihood of Stage IV disease at diagnosis ( OR = 1.96, p < .001). Unmarried males with breast cancer are at greater risk for Stage IV disease at diagnosis and poorer outcomes compared with married males. PMID- 27694552 TI - Canadian Men's Perspectives of Depression: Awareness and Intention to Seek Help. AB - It is often presumed that men are generally unaware of depression being a serious health issue and are unlikely to seek professional help if they became depressed. To test this presumption, Canadian men's ( N = 452) perspectives regarding awareness of depression and likelihood of seeking help for depression were solicited. While 78.7% of respondents recognized depression as a significant health issue for men, only 58.5% felt fairly or very well informed about depression. In terms of help-seeking intentions, 82.6% of respondents indicated that they probably or definitely would seek professional help if depressed. Contrary to popular depictions, the findings suggest that Canadian men are indeed aware of the seriousness of depression as a health issue, yet many are poorly informed about it. Furthermore, most men are well intentioned when it comes to seeking help if they became depressed. The findings imply that greater efforts are required to improve men's understanding of depression (symptoms, triggers, approaches to care), which may help translate intentions to seek help into concrete action. PMID- 27694554 TI - A Content Analysis of YouTubeTM Videos Related to Prostate Cancer. AB - In the United States, prostate cancer is the most common type of cancer in men after skin cancer. There is a paucity of research devoted to the types of prostate cancer information available on social media outlets. YouTubeTM is a widely used video sharing website, which is emerging as commonplace for information related to health. The purpose of this study was to describe the most widely viewed YouTubeTM videos related to prostate cancer. The 100 videos were watched a total of 50,278,770 times. The majority of videos were uploaded by consumers (45.0%) and medical or government professionals (30%). The purpose of most videos (78.0%) was to provide information, followed by discussions of prostate cancer treatment (51%) and prostate-specific antigen testing and routine screening (26%). All videos uploaded by medical and government professionals and 93.8% of videos uploaded by news sources provided information compared with about two thirds of consumer and less than one half of commercial and advertisement videos ( p < .001). As society becomes increasingly technology-based, there is a need to help consumers acquire knowledge and skills to identify credible information to help inform their decisions.

AB - The aim of the current study was to characterize the prevalence of latent groups in terms of smoking, hookah, and alcohol in a sample of Iranian high school students. In this cross-sectional study, 4,422 high school students were assessed in East Azerbaijan Province, Iran. Latent class analysis was applied to determine the subgroups and prevalence of each class using the procLCA in SAS 9.2 software. The prevalence of hookah smoking was the highest among the other substances and had the greatest abuse among males than females. Nearly 86%, 9.5%, and 4.6% of the participants were low risk, tobacco experimenter, and high risk, respectively. The odds ratio indices of membership in each class, compared with the first class, associated with the independent variables. A fair number of students, males in particular, were identified as high risk-takers. Considering the simultaneous incidence of multiple high-risk behaviors, interventions must cover multiple aspects of the issue at the same time.

Great improvements in morbidity and mortality have been obtained with the endovascular approach TEVAR (Thoracic Endovascular Aortic Repair) but this devastating complication continues to severely affect the quality of life, even if the primary success of the procedure - dissection/aneurysm exclusion - has been achieved. Several strategies to deal with this complication have been published in the literature over the time. Knowledge and technology have been evolving from identification of the risk factors associated with spinal cord ischemia, including lessons learned from open surgery, and from developments in the collateral network concept for spinal cord perfusion. In this comprehensive review, the authors cover several topics from the traditional measures comprising haemodynamic control, cerebrospinal drainage and neuroprotective drugs, to the staged-procedures approach, the emerging MISACE (minimally invasive selective segmental artery coil-embolization) and innovative neurologic monitoring such as NIRS (near-infrared spectroscopy) of the collateral network.

AB - Thoracic outlet syndrome, a condition due to neurovascular compression in the upper shoulder region, can be caused by chronic repetitive activity of the upper extremities. Studies have linked upper extremity musculoskeletal disorders to high-performance musicians who play bowed string instruments such as the violin or viola. We report herein a case series of five elite musicians, including three violinists and two violaists, who developed neurogenic thoracic outlet syndrome following years of intense practice. Successful surgical treatment including first rib resection, scalenectomy, and brachial plexus neurolysis was performed in all patients. All patients were able to resume their musical career following surgical treatment. Our report represents the first description of thoracic outlet syndrome in high-performance bowed string instrumentalists. Clinicians should be aware of thoracic outlet syndrome as a differential diagnosis when treating string instrumentalists with upper extremity musculoskeletal ailments.

AB - Kaempferia parviflora (Krachaidum) is a medicinal plant in the family Zingiberaceae. Its rhizome has been used as folk medicine for many centuries. A number of pharmacological studies of Krachaidum had claimed benefits for various ailments. Therefore, this study aimed to systematically search and summarize the clinical evidences of Krachaidum in all identified indications. Of 683 records identified, 7 studies were included. From current clinical trials, Krachaidum showed positive benefits but remained inconclusive since small studies were included. Even though results found that Krachaidum significantly increased hand grip strength and enhanced sexual erotic stimuli, these were based on only 2 studies and 1 study, respectively. With regard to harmful effects, we found no adverse events reported even when Krachaidum 1.35 g/day was used. Therefore, future studies of Krachaidum are needed with regards to both safety and efficacy outcomes.

AB - Poor mood and elevated anxiety are linked to increased incidence of disease. This study examined the effects of sound meditation, specifically Tibetan singing bowl meditation, on mood, anxiety, pain, and spiritual well-being. Sixty-two women and men (mean age 49.7 years) participated. As compared with pre-meditation, following the sound meditation participants reported significantly less tension, anger, fatigue, and depressed mood (all Ps <.001). Additionally, participants who were previously naive to this type of meditation experienced a significantly greater reduction in tension compared with participants experienced in this meditation ( P < .001). Feeling of spiritual well-being significantly increased across all participants ( P < .001). Tibetan singing bowl meditation may be a feasible low-cost low technology intervention for reducing feelings of tension, anxiety, and depression, and increasing spiritual well-being. This meditation type may be especially useful in decreasing tension in individuals who have not previously practiced this form of meditation.

AB - OBJECTIVE: The object of present study was to investigate the effects of direct addition of Tribulus terrestris extract on human sperm parameters. DESIGN: Semen specimens from 40 healthy men volunteers were divided into 4 groups: one group received no treatment (control group) while the others were incubated with 20, 40, and 50 ug/mL of T terrestris extract (experimental groups). Motility, viability, and DNA fragmentation were assessed in all groups. RESULTS: The incubation of human semen with 40 and 50 MUg/mL of T terrestris extract significantly enhanced total sperm motility, number of progressive motile spermatozoa, and curvilinear velocity over 60 to 120 minutes' holding time ( P < .05 or P < < .01). Furthermore, viability was significantly enhanced by using T terrestris extract ( P < .01). CONCLUSIONS: In vitro addition of the T terrestris extract to human sperm could affect male fertility capacity.

PMID- 27694566 TI - The tale wagged by the DAG: broadening the scope of causal inference and explanation for epidemiology. AB - 'Causal inference', in 21st century epidemiology, has notably come to stand for a specific approach, one focused primarily on counterfactual and potential outcome reasoning and using particular representations, such as directed acyclic graphs (DAGs) and Bayesian causal nets. In this essay, we suggest that in epidemiology no one causal approach should drive the questions asked or delimit what counts as useful evidence. Robust causal inference instead comprises a complex narrative, created by scientists appraising, from diverse perspectives, different strands of evidence produced by myriad methods. DAGs can of course be useful, but should not alone wag the causal tale. To make our case, we first address key conceptual issues, after which we offer several concrete examples illustrating how the newly favoured methods, despite their strengths, can also: (i) limit who and what may be deemed a 'cause', thereby narrowing the scope of the field; and (ii) lead to erroneous causal inference, especially if key biological and social assumptions about parameters are poorly conceived, thereby potentially causing harm. As an alternative, we propose that the field of epidemiology consider judicious use of the broad and flexible framework of 'inference to the best explanation', an approach perhaps best developed by Peter Lipton, a philosopher of science who frequently employed epidemiologically relevant examples. This stance requires not only that we be open to being pluralists about both causation and evidence but also that we rise to the challenge of forging explanations that, in Lipton's words, aspire to 'scope, precision, mechanism, unification and simplicity'. PMID- 27694567 TI - Plasma metabolomics identified novel metabolites associated with risk of type 2 diabetes in two prospective cohorts of Chinese adults. AB - BACKGROUND: Metabolomics studies in Caucasians have identified a number of novel metabolites in association with the risk of type 2 diabetes (T2D). However, few prospective metabolomic studies are available in Chinese populations. In the present study, we sought to identify novel metabolites consistently associated with incident T2D in two independent cohorts of Chinese adults. METHODS: We performed targeted metabolomics (52 metabolites) of fasting plasma samples by liquid chromatography-mass spectrometry in two prospective case-control studies nested within the Dongfeng-Tongji (DFTJ) cohort and Jiangsu Non-communicable Disease (JSNCD) cohort. After following for 4.61 +/- 0.15 and 7.57 +/- 1.13 years, respectively, 1039 and 520 eligible participants developed incident T2D in these two cohorts, and controls were 1:1 matched with cases by age (+/- 5 years) and sex. Multivariate conditional logistic regression models were constructed to identify metabolites associated with future T2D risk in both cohorts. RESULTS: We identified four metabolites consistently associated with an increased risk of developing T2D in the two cohorts, including alanine, phenylalanine, tyrosine and palmitoylcarnitine. In the meta-analysis of two cohorts, the odds ratios (95% confidence intervals, CIs) comparing extreme quartiles were 1.79 (1.32-2.42) for alanine, 1.91 (1.41-2.60) for phenylalanine, 1.85 (1.37-2.48) for tyrosine and 1.63 (1.21-2.20) for palmitoylcarnitine (all Ptrend <= 0.01). CONCLUSIONS: We confirmed the association of alanine, phenylalanine and tyrosine with future T2D risk and further identified palmitoylcarnitine as a novel metabolic marker of incident T2D in two prospective cohorts of Chinese adults. Our findings might provide new aetiological insight into the development of T2D. PMID- 27694569 TI - Data Resource Profile: WHO Health Equity Monitor (HEM). PMID- 27694568 TI - Effects of prenatal micronutrient and early food supplementation on metabolic status of the offspring at 4.5 years of age. The MINIMat randomized trial in rural Bangladesh. AB - BACKGROUND: Fetal nutritional insults may alter the later metabolic phenotype. We hypothesized that early timing of prenatal food supplementation and multiple micronutrient supplementation (MMS) would favourably influence childhood metabolic phenotype. METHODS: Pregnant women recruited 1 January to 31 December 2002 in Matlab, Bangladesh, were randomized into supplementation with capsules of either 30 mg of iron and 400 MUg of folic acid, 60 mg of iron and 400 MUg of folic acid, or MMS containing a daily allowance of 15 micronutrients, and randomized to food supplementation (608 kcal) either with early invitation (9 weeks' gestation) or usual invitation (at 20 weeks). Their children (n = 1667) were followed up at 4.5 years with assessment of biomarkers of lipid and glucose metabolism, inflammation and oxidative stress. RESULTS: Children in the group with early timing of food supplementation had lower cholesterol (difference 0.079 mmol/l, 95% confidence interval (CI) -0.156; -0.003), low-density lipoprotein (LDL) (difference -0.068 mmol/l, 95% CI -0.126; -0.011) and ApoB levels (difference -0.017 g/l, 95% CL -0.033; -0.001). MMS supplementation resulted in lower high-density lipoprotein (HDL) (difference -0.028 mmol/l, 95% CL -0.053; -0.002), lower glucose (difference -0.099 mmol/l, 95% CL -0.179; 0.019) and lower insulin-like growth factor 1 (IGF-1) (difference on log scale 0.141 ug/l, 95% CL -0.254; -0.028) than 60 mg iron and 400 MUg folic acid. There were no effects on markers of inflammation or oxidative stress. CONCLUSIONS: Findings suggest that in a population where malnutrition is prevalent, nutrition interventions during pregnancy may modify the metabolic phenotype in the young child that could have consequences for later chronic disease risks. PMID- 27694570 TI - Association between polygenic risk scores for attention-deficit hyperactivity disorder and educational and cognitive outcomes in the general population. AB - Background: Children with a diagnosis of attention-deficit hyperactivity disorder ADHD) have lower cognitive ability and are at risk of adverse educational outcomes; ADHD genetic risks have been found to predict childhood cognitive ability and other neurodevelopmental traits in the general population; thus genetic risks might plausibly also contribute to cognitive ability later in development and to educational underachievement. Methods: We generated ADHD polygenic risk scores in the Avon Longitudinal Study of Parents and Children participants (maximum N : 6928 children and 7280 mothers) based on the results of a discovery clinical sample, a genome-wide association study of 727 cases with ADHD diagnosis and 5081 controls. We tested if ADHD polygenic risk scores were associated with educational outcomes and IQ in adolescents and their mothers. Results: High ADHD polygenic scores in adolescents were associated with worse educational outcomes at Key Stage 3 [national tests conducted at age 13-14 years; beta = -1.4 (-2.0 to -0.8), P = 2.3 * 10 -6 ), at General Certificate of Secondary Education exams at age 15-16 years (beta = -4.0 (-6.1 to -1.9), P = 1.8 * 10 -4 ], reduced odds of sitting Key Stage 5 examinations at age 16-18 years [odds ratio (OR) = 0.90 (0.88 to 0.97), P = 0.001] and lower IQ scores at age 15.5 [beta = -0.8 (-1.2 to -0.4), P = 2.4 * 10 -4 ]. Moreover, maternal ADHD polygenic scores were associated with lower maternal educational achievement [beta = -0.09 (-0.10 to -0.06), P = 0.005] and lower maternal IQ [beta = -0.6 ( 1.2 to -0.1), P = 0.03]. Conclusions: ADHD diagnosis risk alleles impact on functional outcomes in two generations (mother and child) and likely have intergenerational environmental effects.

AB - Total anomalous pulmonary venous connection (TAPVC) is a potentially devastating form of congenital heart disease in which all pulmonary blood flow returns to the systemic venous circulation rather than the left atrium. Anomalous pulmonary venous flow may be obstructed at birth, and affected infants present with severe cyanosis and poor cardiac output unresponsive to standard resuscitation with prostaglandin. Obstructed TAPVC remains one of the few indications for emergent neonatal cardiac surgery. This review will discuss the physiology and perioperative management of isolated TAPVC without associated cardiac lesions. PMID- 27694574 TI - Validation of a Brief Insomnia Severity Measure in Youth Clinically Referred for Sleep Evaluation. AB - Objectives: Evaluate psychometric properties of the Pediatric Insomnia Severity Index (PISI), a brief measure of insomnia severity. Methods: Clinically referred youth ( n = 462; 283 males, 179 females, mean age = 7.28 +/- 2.05 years) and their caregiver(s) completed sleep evaluation including the PISI, Children's Sleep Habits Questionnaire, and sleep disorders inventory for students. Tests of reliability and validity and confirmatory factor analysis (CFA) were conducted to assess PISI psychometric properties. Exploratory analyses were conducted to examine insomnia severity by insomnia diagnosis. Results: Measures of internal consistency for the PISI factor scores varied. CFA indicated that a two-factor model had optimal fit relative to a single-factor solution. Overall, convergent and discriminant validity of PISI factors were supported. Insomnia severity varied by diagnosis. Conclusions: Findings provide preliminary support for the reliability and validity of the PISI within a large pediatric sample and for its clinical utility as a brief measure of insomnia severity. PMID- 27694571 TI - Risk of mortality with concomitant use of tamoxifen and selective serotonin reuptake inhibitors: multi-database cohort study. AB - OBJECTIVE: To compare differences in mortality between women concomitantly treated with tamoxifen and selective serotonin reuptake inhibitors (SSRIs) that are potent inhibitors of the cytochrome-P450 2D6 enzyme (CYP2D6) versus tamoxifen and other SSRIs. DESIGN: Population based cohort study. SETTING: Five US databases covering individuals enrolled in private and public health insurance programs from 1995 to 2013. PARTICIPANTS: Two cohorts of women who started taking tamoxifen. In cohort 1, women started taking an SSRI during tamoxifen treatment. In cohort 2, women were already taking an SSRI when they started taking tamoxifen. MAIN OUTCOME MEASURES: All cause mortality in each cohort in women taking SSRIs that are potent inhibitors of CYP2D6 (paroxetine, fluoxetine) versus other SSRIs. Propensity scores were used to match exposure groups in a variable ratio fashion. Results were measured separately for each cohort and combined hazard ratios calculated from Cox regression models across the two cohorts with random effects meta-analysis. RESULTS: There were 6067 and 8465 new users of tamoxifen in cohorts 1 and 2, respectively. Mean age was 55. A total of 991 and 1014 deaths occurred in cohorts 1 and 2 during a median follow-up of 2.2 (interquartile range 0.9-4.5) and 2.0 (0.8-3.9) years, respectively. The pooled hazard ratio for death for potent inhibitors (rate 58.6/1000 person years) compared with other SSRIs (rate 57.9/1000 person years) across cohorts 1 and 2 was 0.96 (95% confidence interval 0.88 to 1.06). Results were consistent across sensitivity analyses. CONCLUSION: Concomitant use of tamoxifen and potent CYP2D6 inhibiting SSRIs versus other SSRIs was not associated with an increased risk of death.

PMID- 27694575 TI - Barriers and outcomes of an evidence-based approach to diagnosis and management of chronic obstructive pulmonary disease (COPD) in Australia: a qualitative study. AB - Background: Chronic obstructive pulmonary disease (COPD) is commonly managed in primary care but there is poor awareness of evidence-based guidelines and the quality and interpretation of spirometry is suboptimal. Objectives: The aims of this qualitative study were to explore how an intervention involving case finding and management of COPD was implemented, and the extent to which the GPs and practice nurses (PNs) worked in partnership to diagnose and manage COPD. Methods: Semi-structured interviews with PNs (n = 7), GPs (n = 4) and patients (n = 26) who had participated in the Primary care EarLy Intervention for Copd mANagement (PELICAN) study. The Theoretical Domains Framework was used to guide the coding and analysis of the interviews with PN and GPs. The patient interviews were analysed thematically. Results: PNs developed technical skills and understood the requirements for good-quality spirometry. However, many lacked confidence in its interpretation and felt this was not part of their professional role. This was reflected in responses from the GPs. Once COPD was diagnosed, the GPs tended to manage the patients with the PNs less involved. This was in contrast with PNs' active role in managing patients with other chronic diseases such as diabetes. The extent to which the GPs and PNs worked in partnership to manage COPD varied. Conclusions: PNs improved their skills and confidence in performing spirometry. Beliefs about their professional role, identity and confidence influenced the extent to which PNs were involved in interpretation of the spirometry results and managing the patient in partnership with the GP. PMID- 27694577 TI - Morphometric covariation between palatal shape and skeletal pattern in children and adolescents: a cross-sectional study. AB - Objective: To assess shape covariation of the palate and craniofacial complex (CFC) in children and adolescents. Methods: Pre-treatment lateral cephalometric radiographs and corresponding maxillary casts of 100 children (8-10 years) and 100 adolescents (15-20 years) were digitized. Exclusion criteria were previous orthodontic treatment, craniofacial syndromes, mouth breathing, finger sucking, crossbite, tooth agenesis, and tooth impaction. Palatal shape was described with 239 surface and curve semilandmarks and craniofacial shape with 10 fixed landmarks and 117 curve semilandmarks. Procrustes superimposition and principal component analysis were applied for evaluation of shape variability. Shape covariation between palate and CFC was assessed with partial least squares analysis. Results: The first five principal components explained 77 per cent (palate) and 60 per cent (CFC) of total shape variability. The palate varied mainly in height (adolescent group) and width-length (both groups), whereas the CFC varied mainly in the vertical dimension. Significant covariation was found between the craniofacial and palatal components (RV coefficient: 0.27, children; RV: 0.23, adolescents). Variation of the CFC in the vertical and anteroposterior direction was mainly related to variation in the height-width and the width length ratio of the palate, respectively. Limitations: The use of lateral cephalometric radiographs eliminated the transverse dimension from the craniofacial shape analysis. The study was cross-sectional, so the observed intergroup differences should be interpreted with caution. Conclusions: Covariation strength and pattern were similar in children and adolescents. The closer a subject was to the high-angle end of the variability spectrum, the higher and narrower was the palate, and conversely. PMID- 27694578 TI - Redox-assisted regulation of Ca2+ homeostasis in the endoplasmic reticulum by disulfide reductase ERdj5. AB - Calcium ion (Ca2+) is an important second messenger that regulates numerous cellular functions. Intracellular Ca2+ concentration ([Ca2+]i) is strictly controlled by Ca2+ channels and pumps on the endoplasmic reticulum (ER) and plasma membranes. The ER calcium pump, sarco/endoplasmic reticulum calcium ATPase (SERCA), imports Ca2+ from the cytosol into the ER in an ATPase activity dependent manner. The activity of SERCA2b, the ubiquitous isoform of SERCA, is negatively regulated by disulfide bond formation between two luminal cysteines. Here, we show that ERdj5, a mammalian ER disulfide reductase, which we reported to be involved in the ER-associated degradation of misfolded proteins, activates the pump function of SERCA2b by reducing its luminal disulfide bond. Notably, ERdj5 activated SERCA2b at a lower ER luminal [Ca2+] ([Ca2+]ER), whereas a higher [Ca2+]ER induced ERdj5 to form oligomers that were no longer able to interact with the pump, suggesting [Ca2+]ER-dependent regulation. Binding Ig protein, an ER-resident molecular chaperone, exerted a regulatory role in the oligomerization by binding to the J domain of ERdj5. These results identify ERdj5 as one of the master regulators of ER calcium homeostasis and thus shed light on the importance of cross talk among redox, Ca2+, and protein homeostasis in the ER.

AB - Social media sites are rapidly becoming one of the most important forums for public deliberation about advocacy issues. However, social scientists have not explained why some advocacy organizations produce social media messages that inspire far-ranging conversation among social media users, whereas the vast majority of them receive little or no attention. I argue that advocacy organizations are more likely to inspire comments from new social media audiences if they create "cultural bridges," or produce messages that combine conversational themes within an advocacy field that are seldom discussed together. I use natural language processing, network analysis, and a social media application to analyze how cultural bridges shaped public discourse about autism spectrum disorders on Facebook over the course of 1.5 years, controlling for various characteristics of advocacy organizations, their social media audiences, and the broader social context in which they interact. I show that organizations that create substantial cultural bridges provoke 2.52 times more comments about their messages from new social media users than those that do not, controlling for these factors. This study thus offers a theory of cultural messaging and public deliberation and computational techniques for text analysis and application-based survey research.

PMID- 27694579 TI - Activation of Notch1 synergizes with multiple pathways in promoting castration resistant prostate cancer. AB - Metastatic castration-resistant prostate cancer (CRPC) is the primary cause of prostate cancer-specific mortality. Defining new mechanisms that can predict recurrence and drive lethal CRPC is critical. Here, we demonstrate that localized high-risk prostate cancer and metastatic CRPC, but not benign prostate tissues or low/intermediate-risk prostate cancer, express high levels of nuclear Notch homolog 1, translocation-associated (Notch1) receptor intracellular domain. Chronic activation of Notch1 synergizes with multiple oncogenic pathways altered in early disease to promote the development of prostate adenocarcinoma. These tumors display features of epithelial-to-mesenchymal transition, a cellular state associated with increased tumor aggressiveness. Consistent with its activation in clinical CRPC, tumors driven by Notch1 intracellular domain in combination with multiple pathways altered in prostate cancer are metastatic and resistant to androgen deprivation. Our study provides functional evidence that the Notch1 signaling axis synergizes with alternative pathways in promoting metastatic CRPC and may represent a new therapeutic target for advanced prostate cancer.

AB - As residency training programmes around the globe move towards competency-based medical education (CBME), there is a need to review current teaching and assessment practices as they relate to education in orthopaedic trauma. Assessment is the cornerstone of CBME, as it not only helps to determine when a trainee is fit to practice independently, but it also provides feedback on performance and guides the development of competence. Although a standardised core knowledge base for trauma care has been developed by the leading national accreditation bodies and international agencies that teach and perform research in orthopaedic trauma, educators have not yet established optimal methods for assessing trainees' performance in managing orthopaedic trauma patients. This review describes the existing knowledge from the literature on assessment in orthopaedic trauma and highlights initiatives that have recently been undertaken towards CBME in the United Kingdom, Canada and the United States. In order to support a CBME approach, programmes need to improve the frequency and quality of assessments and improve on current formative and summative feedback techniques in order to enhance resident education in orthopaedic trauma.

PMID- 27694585 TI - A pre-operative predictive score for the outcome of eccentric rotational acetabular osteotomy in the treatment of acetabular dysplasia and early osteoarthritis of the hip in adults. AB - AIMS: The influence of identifiable pre-operative factors on the outcome of eccentric rotational acetabular osteotomy (ERAO) is unknown. We aimed to determine the factors that might influence the outcome, in order to develop a scoring system for predicting the prognosis for patients undergoing this procedure. PATIENTS AND METHODS: We reviewed 700 consecutive ERAOs in 54 men and 646 women with symptomatic acetabular dysplasia or early onset osteoarthritis (OA) of the hip, which were undertaken between September 1989 and March 2013. The patients' pre-operative background, clinical and radiological findings were examined retrospectively. Multivariate Cox regression analysis was performed using the time from the day of surgery to a conversion to total hip arthroplasty (THA) as an endpoint. A risk score was calculated to predict the prognosis for conversion to THA, and its predictive capacity was investigated. RESULTS: The congruity of the hip, age, the pre-operative minimum width of the joint space and range of abduction were identified as factors predicting conversion to THA. For three groups of patients (scoring 0 to 5, 6 to 7, and 8 to 9 points), the Kaplan Meier event-free rates of survival at 15 years post-operatively for conversion to THA were 99.6%, 85.2% and 67.3%, respectively. CONCLUSION: These four pre operative factors are easily measured and predict the prognosis for patients following ERAO. They may be used for decision making when offering surgical treatment to patients with acetabular dysplasia and early onset osteoarthritis. Cite this article: Bone Joint J 2016;98-B:1326-32. PMID- 27694586 TI - Comparison of femoral component migration between Refobacin bone cement R and Palacos R + G in cemented total hip arthroplasty: A randomised controlled roentgen stereophotogrammetric analysis and clinical study. AB - AIMS: The widely used and well-proven Palacos R (a.k.a. Refobacin Palacos R) bone cement is no longer commercially available and was superseded by Refobacin bone cement R and Palacos R + G in 2005. However, the performance of these newly introduced bone cements have not been tested in a phased evidence-based manner, including roentgen stereophotogrammetric analysis (RSA). PATIENTS AND METHODS: In this blinded, randomised, clinical RSA study, the migration of the Stanmore femoral component was compared between Refobacin bone cement R and Palacos R + G in 62 consecutive total hip arthroplasties. The primary outcome measure was femoral component migration measured using RSA and secondary outcomes were Harris hip score (HHS), Hip disability and Osteoarthritis Outcome Score (HOOS), EuroQol 5D (EQ-5D) and Short Form 36 (SF-36). RESULTS: Femoral component migration was comparable between Refobacin bone cement R and Palacos R + G during the two-year follow-up period with an estimated mean difference of 0.06 mm of subsidence (p = 0.56) and 0.08 degrees of retroversion (p = 0.82). Five hips (three Refobacin bone cement R and two Palacos R + G) showed non-stabilising, continuous migration; the femoral cement mantle in these hips, was mean 0.7 mm thicker (p = 0.02) and there were more radiolucencies at the bone-cement interface (p = 0.004) in comparison to hips showing stabilising migration. Post-operative HHS was comparable throughout the follow-up period (p = 0.62). HOOS, EQ5D, and SF-36 scores were also comparable (p-values > 0.05) at the two-year follow-up point. CONCLUSION: Refobacin bone cement R and Palacos R + G show comparable component migration and clinical outcome during the first two post-operative years. Hips showing continuous migration are at risk for early failure. However, this seems to be unrelated to cement type, but rather to cementing technique.

AB - AIMS: Accurate placement of the acetabular component during total hip arthroplasty (THA) is an important factor in the success of the procedure. However, the reported accuracy varies greatly and is dependent upon whether free hand or navigated techniques are used. The aim of this study was to assess the accuracy of an instrument system that incorporates 3D printed, patient-specific guides designed to optimise the placement of the acetabular component. PATIENTS AND METHODS: A total of 100 consecutive patients were prospectively enrolled and the accuracy of placement of the acetabular component was measured using post operative CT scans. PATIENTS AND METHODS: A total of 100 consecutive patients were prospectively enrolled and the accuracy of placement of the acetabular component was measured using post-operative CT scans. CONCLUSION: Accurate placement of the acetabular component can be achieved using patient-specific guides and is superior to free hand techniques and comparable to navigated and robotic techniques.

AB - AIMS: Periprosthetic fracture (PF) after primary total hip arthroplasty (THA) is an uncommon but potentially devastating complication. This study aims to investigate the influence of cemented stem designs on the risk of needing a revision for a PF. PATIENTS AND METHODS: We analysed data on 257 202 primary THAs with cemented stems and 390 linked first revisions for PF recorded in the National Joint Registry (NJR) of England, Wales and Northern Ireland to determine if a cemented femoral stem brand was associated with the risk of having revision for a PF after primary THA. All cemented femoral stem brands with more than 10 000 primary operations recorded in the NJR were identified. The four most commonly used cemented femoral stems were the Exeter V40 (n = 146 409), CPT (n = 24 300), C-Stem (n = 15 113) and Charnley (n = 20 182). We compared the revision risk ratios due to PF amongst the stems using a Poisson regression model adjusting for patient factors. Compared with the Exeter V40, the age, gender and ASA grade adjusted revision rate ratio was 3.89 for the cemented CPT stem (95% confidence interval (CI) 3.07 to 4.93), 0.89 for the C-Stem (95% CI 0.57 to 1.41) and 0.41 for the Charnley stem (95% CI 0.24 to 0.70). CONCLUSIONS: The limitations of the study include incomplete data capture, analysis of only PF requiring revision and that observation does not imply causality. Nevertheless, this study demonstrates that the choice of a cemented stem may influence the risk of revision for PF. Cite this article: Bone Joint J 2016;98-B:1347-54. PMID- 27694589 TI - The diagnostic thresholds for synovial fluid analysis in late periprosthetic infection of the hip depend on the duration of symptoms. AB - AIMS: We hypothesised that the synovial white blood cell (WBC) count in patients with a late periprosthetic joint infection (PJI) of the hip would depend on the duration of a patient's symptoms, and that the optimal diagnostic threshold would also depend on this period of time. PATIENTS AND METHODS: The synovial WBC count and percentage of polymorphonuclear cells (%PMN), and the serum CRP and ESR levels obtained > six weeks after primary THA were compared between 50 infected and 88 non-infected THAs, and in patients with symptoms for more than or less than two weeks. Diagnostic thresholds for the synovial WBC count were calculated using area under the curve calculation. RESULTS: The synovial WBC count was significantly higher in patients with symptoms for <= two weeks compared with those with symptoms for > two weeks (p = 0.03). The optimal threshold for diagnosing PJI for the synovial WBC count was 5750 cells/uL (sensitivity 94; specificity 100; PPV 100%; NPV 89%; AUC 99%) and 1556 cells/uL (sensitivity 91; specificity 94; PPV 87% and NPV 97%; AUC 95%), respectively. The thresholds for the cut-offs based on duration of symptoms improved the diagnostic performance of this test. CONCLUSION: This study shows that the diagnostic thresholds for synovial fluid analysis in late periprosthetic infection following THA may depend on duration of symptoms.

AB - AIMS: Our aim was to compare kinematic with mechanical alignment in total knee arthroplasty (TKA). PATIENTS AND METHODS: We performed a prospective blinded randomised controlled trial to compare the functional outcome of patients undergoing TKA in mechanical alignment (MA) with those in kinematic alignment (KA). A total of 71 patients undergoing TKA were randomised to either kinematic (n = 36) or mechanical alignment (n = 35). Pre- and post-operative hip-knee-ankle radiographs were analysed. The knee injury and osteoarthritis outcome score (KOOS), American Knee Society Score, Short Form-36, Euro-Qol (EQ-5D), range of movement (ROM), two minute walk, and timed up and go tests were assessed pre operatively and at six weeks, three and six months and one year post-operatively. RESULTS: A total of 78% of the kinematically aligned group (28 patients) and 77% of the mechanically aligned group (27 patients) were within 3 degrees of their pre-operative plan. There were no statistically significant differences in the mean KOOS (difference 1.3, 95% confidence interval (CI) -9.4 to 12.1, p = 0.80), EQ-5D (difference 0.8, 95% CI -7.9 to 9.6, p = 0.84), ROM (difference 0.1, 95% CI -6.0 to 6.1, p = 0.99), two minute distance tolerance (difference 20.0, 95% CI 52.8 to 92.8, p = 0.58), or timed up and go (difference 0.78, 95% CI -2.3 to 3.9, p = 0.62) between the groups at one year. CONCLUSION: Kinematically aligned TKAs appear to have comparable short-term results to mechanically aligned TKAs with no significant differences in function one year post-operatively. Further research is required to see if any theoretical long-term functional benefits of kinematic alignment are realised or if there are any potential effects on implant survival.

AB - AIMS: The surgical management of ankle arthritis with tibiotalar arthrodesis is known to alter gait, as compared with normal ankles. The purpose of this study was to assess post-operative gait function with gait before arthrodesis. PATIENTS AND METHODS: We prospectively studied 20 patients who underwent three-dimensional gait analysis before and after tibiotalar arthrodesis. Cadence, step length, walking velocity and total support time were assessed. Kinetic parameters, including the moment and power of the ankle in the sagittal plane and hip power were also recorded. RESULTS: Significant improvement was recorded across numerous parameters compared with pre-operative measurements. Temporal-spatial data demonstrated a significant increase in step length (p = 0.003) and velocity (p = < 0.001). Total support time decreased for the unaffected limb (p = 0.01). Kinematic results demonstrated that in the affected limb, total sagittal range of movement did not change significantly (p = 0.1259). However, the arc of movement had a near congruent shift with mean maximal dorsiflexion increasing from 5 degrees (-17 degrees to 16 degrees ) to 12 degrees (5 degrees to 18 degrees ) (p < 0.001) and mean maximal plantarflexion decreasing from 6.8 degrees (6 degrees to 21 degrees ) to 0.9 degrees (-9 degrees to 8 degrees ) (p = 0.003). Mean hip joint range of movement increased by 6 degrees (-7 degrees to 24 degrees ; p = 0.003). Kinetic results demonstrated no statistically significant change in ankle power (p = 0.1292). However, there was an increase in ankle moment (p = 0.04) and hip power (p = 0.01) in the surgically treated extremity. Sagittal plane range of movement was not reduced after tibiotalar fusion. CONCLUSION: Although following tibiotalar arthrodesis the gait demonstrated never matched the gait shown in unaffected ankles, compared with the pre-operative analysis there was improvement in numerous temporal-spatial, kinematic, and kinetic measures.

AB - AIMS: This is the first prospective study to report the pre- and post-operative patient reported outcomes and satisfaction scores following excision of interdigital Morton's neuroma. PATIENTS AND METHODS: Between May 2006 and April 2013, we prospectively studied 99 consecutive patients (111 feet) who were to undergo excision of a Morton's neuroma. There were 78 women and 21 men with a mean age at the time of surgery of 56 years (22 to 78). Patients completed the Manchester-Oxford Foot Questionnaire (MOXFQ), Short Form-12 (SF-12) and a supplementary patient satisfaction survey three months pre-operatively and six months post-operatively. RESULTS: Statistically significant differences were found between the mean pre- and post-operative MOXFQ and the physical component of the SF-12 scores (p = 0.00081 and p = 0.00092 respectively). Most patients reported their overall satisfaction as excellent (n = 49, 49.5%) or good (n = 29, 29.3%), but ten patients were dissatisfied, reporting poor (n = 8, 8.1%) or very poor (n = 2, 2.0%) results. Only 63 patients (63%) were pain-free at follow-up: in eight patients (8.1%), the MOXFQ score worsened. There was no statistically significant difference in outcome between surgery on single or multiple sites. However, the MOXFQ scores were significantly worse after revision surgery (p = 0.004). CONCLUSIONS: The patient-reported outcomes after resection of a symptomatic Morton's neuroma are acceptable but may not be as good as earlier studies suggest. Surgery at several sites can be undertaken safely but caution should be exercised when considering revision surgery. Cite this article: Bone Joint J 2016;98-B:1376-81. PMID- 27694593 TI - Outcomes following femoral lengthening: An initial comparison of the Precice intramedullary lengthening nail and the LRS external fixator monorail system. AB - AIMS: Patients undergoing femoral lengthening by external fixation tolerate treatment less well when compared to tibial lengthening. Lengthening of the femur with an intramedullary device may have advantages. PATIENTS AND METHODS: We reviewed all cases of simple femoral lengthening performed at our unit from 2009 to 2014. Cases of nonunions, concurrent deformities, congenital limb deficiencies and lengthening with an unstable hip were excluded, leaving 33 cases (in 22 patients; 11 patients had bilateral procedures) for review. Healing index, implant tolerance and complications were compared. RESULTS: In 20 cases (15 patients) the Precice lengthening nail was used and in 13 cases (seven patients) the LRS external fixator system. The desired length was achieved in all cases in the Precice group and in 12 of 13 cases in the LRS group. The mean healing index was 31.3 days/cm in the Precice and 47.1 days/cm in the LRS group (p < 0.001). This was associated with an earlier ability to bear full weight without aids in the Precice group. There were more complications with LRS lengthening, including pin site infections and regenerate deformity. Implant tolerance and the patients' perception of the cosmetic result were better with the Precice treatment. CONCLUSION: Femoral lengthening with the Precice femoral nail achieved excellent functional results with fewer complications and greater patient satisfaction when compared with the LRS system in our patients.

AB - AIMS: The aim of this study was to analyse human muscle tissue before and after rotator cuff repair to look for evidence of regeneration, and to characterise the changes seen in the type of muscle fibre. PATIENTS AND METHODS: Patients were assessed pre-operatively and one year post-operatively using the Oxford Shoulder Score (OSS) and MRI. The cross-sectional area and distribution of the type of muscle fibre were assessed on biopsies, which were taken at surgery and one year post-operatively. Paired samples from eight patients were analysed. There were three men and five women with a mean age of 63 years (50 to 73). RESULTS: All but one patient showed improvement in OSS (p = 0.004). The mean increase in the cross sectional area of the muscle was 1220 MUm2 (-801 to 3712; p = 0.03). There was a reduction of type 2a fibres (p = 0.02). A clear relationship could not be seen between the MRI findings and the histological appearances. CONCLUSION: This is the first study to provide evidence that atrophy of the supraspinatus muscle is reversible. Changes in the types of fibre are discussed. MRI assessment of muscle atrophy may not be fully representative of myofibre atrophy. Cite this article: Bone Joint J 2016;98-B:1389-94. PMID- 27694595 TI - Anatomy of the terminal branch of the posterior circumflex humeral artery: relevance to the deltopectoral approach to the shoulder. AB - AIMS: Despite the expansion of arthroscopic surgery of the shoulder, the open deltopectoral approach is increasingly used for the fixation of fractures and arthroplasty of the shoulder. The anatomy of the terminal branches of the posterior circumflex humeral artery (PCHA) has not been described before. We undertook an investigation to correct this omission. PATIENTS AND METHODS: The vascular anatomy encountered during 100 consecutive elective deltopectoral approaches was recorded, and the common variants of the terminal branches of the PCHA are described. RESULTS: In total, 92 patients (92%) had a terminal branch that crossed the space between the deltoid and the proximal humerus and which was therefore vulnerable to tearing or avulsion during the insertion of the blade of a retractor during the deltopectoral approach to the shoulder. In 75 patients (75%) there was a single vessel, in 16 (16%) a double vessel and in one a triple vessel. CONCLUSION: The relationship of these vessels to the landmark of the tendon of the insertion of pectoralis major into the proximal humerus is described. Damage to these previously undocumented branches can cause persistent bleeding leading to prolonged surgery and post-operative haematoma and infection, as well as poor visualisation during the procedure.

PMID- 27694596 TI - Prospective randomised comparison of ring versus rail fixator in infected gap nonunion of tibia treated with distraction osteogenesis. AB - AIMS: This is a prospective randomised study which compares the radiological and functional outcomes of ring and rail fixators in patients with an infected gap (> 3 cm) nonunion of the tibia. PATIENTS AND METHODS: Between May 2008 and February 2013, 70 patients were treated at our Institute for a posttraumatic osseocutaneous defect of the tibia measuring at least 3 cm. These were randomised into two groups of 35 patients using the lottery method. Group I patients were treated with a ring fixator and group II patients with a rail fixator. The mean age was 33.2 years (18 to 64) in group I and 29.3 years (18 to 65) in group II. The mean bone gap was 5.84 cm in group I and 5.78 cm in group II. The mean followup was 33.8 months in group I and 32.6 months in group II. Bone and functional results were assessed using the classification of the Association for the Study and Application of the Method of Ilizarov (ASAMI). Functional results were also assessed at six months using the short musculoskeletal functional assessment (SMFA) score. RESULTS: The bone result was excellent, good, fair and poor in 21, 12, 0 and 2 in group I; and 14, 15, 3, and 3 in group II, respectively. The functional results were excellent, good, fair, poor and failure in 16, 17, 1, 0 and 1 in group I; and 22, 10, 0, 3 and 0 in group II, respectively. Both fixator systems achieved comparable rates of union and functional outcomes. The rate of deep pintract infection was significantly higher in the rail fixator group but patients found it more comfortable. CONCLUSION: We recommend the use of a ring fixator in patients with a bone gap of more than 6 cm. Patients with a bone gap up to 6 cm can be managed with either a ring or rail fixator.

AB - AIMS: We present an audit comparing our level I major trauma centre's data for a cohort of patients with hip fractures in the National Hip Fracture Database (NHFD) with locally held data on these patients. PATIENTS AND METHODS: A total of 2036 records for episodes between July 2009 and June 2014 were reviewed. RESULTS: The demographics of nine patients were recorded incorrectly. The rate of incorrect data in operation codes was most significant with overall accuracy of 0.637 (95% CI 0.615 to 0.658). The sensitivity of NHFD coding ranged from 0.250 to 1.000 and the specificity 0.879 to 0.999. The recording of cementation had a sensitivity of 0.932 and specificity of 0.713. The recording of total hip arthroplasty had a sensitivity of 0.739 and specificity of 0.983. The overall accuracy of mortality data was 0.942 (95% CI 0.931 to 0.952), with sensitivity of 0.967 and specificity of 0.419. CONCLUSION: This paper highlights the need for local audit of the integrity of data uploaded to the NHFD. Cite this article: Bone Joint J 2016;98-B:1406-9. PMID- 27694598 TI - The long-term outcome of childhood supracondylar humeral fractures: A population based follow up study with a minimum follow up of ten years and normal matched comparisons. AB - AIMS: We present the clinical and radiographic outcome of 81 children with Gartland type I to III supracondylar humeral fractures at a minimum follow-up of ten years (mean 12.1 years; 10.3 to 16.1) following injury. PATIENTS AND METHODS: The clinical and functional outcomes are compared with normal age- and gender matched individuals. The population-based study setting was first identified from the institutional registries; the rate of participation was 76%. Controls were randomly selected from Finnish National Population Registry. RESULTS: According to Flynn's criteria, most fractures (75.3%) resulted in a satisfactory ("good or excellent") outcome. Satisfactory recovery was achieved in 75.0% of type I fractures treated by closed splinting (p = 0.013). Type II fractures were associated with both satisfactory (57.7%) and unsatisfactory (42.3%) results, regardless of the type of treatment, although the numbers were small in the sub groups. Most type III fractures were treated operatively, and most (76%) had a satisfactory outcome according to Flynn's criteria (p = 0.015). Compared with none among the normal subjects, flexion of the elbow was reduced by > 10 degrees at long-term follow-up in 20 cases (24.7%, p < 0.001) and 9 (11.1%) had a reduced flexion of > 15 degrees (p = 0.004). In patients who had sustained a type III fracture, the carrying angle was decreased by 35.7% (from 9.8 degrees to 6.3 degrees ; p = 0.048). All patients achieved an excellent Mayo Elbow Performance Score (mean 96.4 points). CONCLUSION: The long-term outcome of extension-type supracondylar humeral fractures is generally good, but not exclusively benign, with the potential for long-term pain and ulnar nerve sensitivity, and a decrease in grip strength and range of movement in type II and type III fractures. Bony remodelling cannot be relied upon to correct any residual deformity. In particular, type II fractures have impaired long-term recovery and justify individual consideration in their treatment.

PMID- 27694599 TI - Can a urine dipstick test be used to assess smoking status in patients undergoing planned orthopaedic surgery? a prospective cohort study. AB - AIMS: Smoking is associated with post-operative complications but smokers often under-report the amount they smoke. Our objective was to determine whether a urine dipstick test could be used as a substitute for quantitative cotinine assays to determine smoking status in patients. PATIENTS AND METHODS: Between September 2013 and July 2014 we conducted a prospective cohort study in which 127 consecutive patients undergoing a planned foot and ankle arthrodesis or osteotomy were included. Patients self-reported their smoking status and were classified as: 'never smoked' (61 patients), 'ex-smoker' (46 patients), or 'current smoker' (20 patients). Urine samples were analysed with cotinine assays and cotinine dipstick tests. RESULTS: There was a high degree of concordance between dipstick and assay results (Kappa coefficient = 0.842, p < 0.001). Compared with the quantitative assay, the dipstick had a sensitivity of 88.9% and a specificity of 97.3%. Patients claiming to have stopped smoking just before surgery had the highest rate of disagreement between reported smoking status and urine testing. CONCLUSION: Urine cotinine dipstick testing is cheap, fast, reliable, and easy to use. It may be used in place of a quantitative assay as a screening tool for detecting patients who may be smoking. A positive test may be used as a trigger for further assessment and counselling. Cite this article: Bone Joint J 2016;98 B:1418-24. PMID- 27694600 TI - Doctors in space (ships): biomedical uncertainties and medical authority in imagined futures. AB - There has been considerable interest in images of medicine in popular science fiction and in representations of doctors in television fiction. Surprisingly little attention has been paid to doctors administering space medicine in science fiction. This article redresses this gap. We analyse the evolving figure of 'the doctor' in different popular science fiction television series. Building upon debates within Medical Sociology, Cultural Studies and Media Studies we argue that the figure of 'the doctor' is discursively deployed to act as the moral compass at the centre of the programme narrative. Our analysis highlights that the qualities, norms and ethics represented by doctors in space (ships) are intertwined with issues of gender equality, speciesism and posthuman ethics. We explore the signifying practices and political articulations that are played out through these cultural imaginaries. For example, the ways in which 'the simple country doctor' is deployed to help establish hegemonic formations concerning potentially destabilising technoscientific futures involving alternative sexualities, or military dystopia. Doctors mostly function to provide the ethical point of narrative stability within a world in flux, referencing a nostalgia for the traditional, attentive, humanistic family physician. The science fiction doctor facilitates the personalisation of technological change and thus becomes a useful conduit through which societal fears and anxieties concerning medicine, bioethics and morality in a 'post 9/11' world can be expressed and explored.

Although extensive cancer research has been conducted utilizing animal models for elucidating mechanisms and developing therapeutics, the concepts in a good model design and its application have not been well elaborated. In this review, we discuss the theory underlying biological modeling and the process of producing a valuable and relevant animal model. Several renowned examples in the history of cancer research will be used to illustrate how modeling can be translatable to clinical applications. Finally, we will also discuss how the advances in cancer genomics and cancer modeling will influence each other going forward. Cancer Res; 76(20); 5921-5. (c)2016 AACR.

The most malignant IBD-associated CRC type has been highlighted as colitis-associated cancer (CAC). However, lack of CAC cases and difficulties of the long follow-up research have challenged researchers in molecular mechanism probing. Here, we established pre-CAC mouse models (dextran sulfate sodium [DSS] group and azoxymethane [AOM] group) and CAC mouse model (DSS/AOM group) to mimic human CAC development through singly or combinational treatment with DSS and AOM followed by disease activity index analysis. We found that these CAC mice showed much more severe disease phenotype, including serious diarrhea, body weight loss, rectal prolapse and bleeding, bloody stool, tumor burden, and bad survival. By detecting expression patterns of several therapeutic targets-Apc, p53, Kras, and TNF-alpha-in these mouse models through western blot, histology analysis, qRT-PCR, and ELISA methods, we found that the oncogene Kras expression remained unchanged, while the tumor suppressors-Apc and p53 expression were both significantly downregulated with malignancy progression from pre-CAC to CAC, and TNF-alpha level was elevated the most in CAC mice blood which is of potential clinical use. These data indicated the successful establishment of CAC development mouse models, which mimics human CAC well both in disease phenotype and molecular level, and highlighted the promoting role of inflammation in CAC progression. This useful tool will facilitate the further study in CAC molecular mechanism. PMID- 27694613 TI - Effects of tranexamic acid on coagulation indexes of patients undergoing heart valve replacement surgery under cardiopulmonary bypass. AB - This study aims to explore the effects of tranexamic acid on the coagulation indexes of patients undergoing heart valve replacement surgery under the condition of cardiopulmonary bypass (CPB). One hundred patients who conformed to the inclusive criteria were selected and divided into a tranexamic acid group and a non-tranexamic acid group. They all underwent heart valve replacement surgery under CPB. Patients in the tranexamic acid group were intravenously injected with 1 g of tranexamic acid (100 mL) at the time point after anesthesia induction and before skin incision and at the time point after the neutralization of heparin. Patients in the non-tranexamic acid group were given 100 mL of normal saline at corresponding time points, respectively. Then the coagulation indexes of the two groups were analyzed. The activated blood clotting time (ACT) of the two groups was within normal scope before CPB, while four coagulation indexes including prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), and fibrinogen (FIB) had significant increases after surgery; the PT and INR of the tranexamic acid group had a remarkable decline after surgery. All the findings suggest that the application of tranexamic acid in heart valve replacement surgery under CPB can effectively reduce intraoperative and postoperative blood loss.

AB - Animal experiments that are conducted worldwide contribute to significant findings and breakthroughs in the understanding of the underlying mechanisms of various diseases, bringing up appropriate clinical interventions. However, their predictive value is often low, leading to translational failure. Problems like translational failure of animal studies and poorly designed animal experiments lead to loss of animal lives and less translatable data which affect research outcomes ethically and economically. Due to increasing complexities in animal usage with changes in public perception and stringent guidelines, it is becoming difficult to use animals for conducting studies. This review deals with challenges like poor experimental design and ethical concerns and discusses key concepts like sample size, statistics in experimental design, humane endpoints, economic assessment, species difference, housing conditions, and systematic reviews and meta-analyses that are often neglected. If practiced, these strategies can refine the procedures effectively and help translate the outcomes efficiently.

AB - Assistive technologies can improve the quality of life of people diagnosed with different forms of social communication disorders. We report on the design and evaluation of an affective avatar aimed at engaging the user in a social interaction with the purpose of assisting in communication therapies. A human avatar taxonomy is proposed to assist the design of affective avatars aimed at addressing social communication disorder. The avatar was evaluated with 30 subjects to assess how effectively it conveys the desired emotion and elicits empathy from the user. Results provide evidence that users become used to the avatar after a number of interactions, and they perceive the defined behavior as being logical. The users' interactions with the avatar entail affective reactions, including the mimic emotions that users felt, and establish a preliminary ground truth about prototypic empathic interactions with avatars that is being used to train learning algorithms to support social communication disorder evaluation.

AB - The prevalence of health problems in the offspring of pregnant diabetic mothers has recently been verified. Therefore, the present study was designed to investigate the influence of dietary camel whey protein (CWP), administered as a supplement to streptozotocin (STZ)-induced diabetic pregnant mice, on the efficiency of the immune system of the offspring. Three groups of female mice (n = 10) were used: non-diabetic control mice, diabetic mice, and diabetic mice orally administered CWP during the pregnancy and lactation periods. We then tested the immune response of B and T cells in adult male offspring (n = 15 in each group) by using flow cytometry, western blotting, and ELISAs. Our data demonstrated that the offspring of diabetic dams exhibited several postpartum complications, such as significant aberrant overexpression of activating transcription factor-3 (ATF-3), significant elevation of the plasma levels of pro inflammatory cytokines (IL-1beta, IL-6, and TNF-alpha) and reactive oxygen species (ROS), marked decreases in the plasma levels of IL-2 and IL-7, significant inhibition of CCL21- and CXCL12-mediated chemotaxis of B- and T lymphocytes, and a marked decrease in the proliferative capacity of antigen stimulated B- and T-lymphocytes. Interestingly, administration of CWP to diabetic dams substantially restored the expression of ATF-3 and the levels of ROS, pro inflammatory cytokines, IL-2, and IL-7 in the offspring. Furthermore, the chemotaxis of B- and T-lymphocytes toward CCL21 and CXCL12 and the proliferative capacities of these lymphocytes were restored in the male offspring of diabetic mice administered CWP. Our data provide evidence of a protective role of CWP in decreasing the tendency of the offspring of diabetic mothers to develop diabetes and related complications.

AB - OBJECTIVE: Portal pressure gradient (PPG) after transjugular intrahepatic portosystemic shunt (TIPS) <12 mmHg has been reported as the only factor predictive of increase in platelet count. As flow velocities measured on Doppler ultrasound are related to pressure gradient based on the Bernoulli equation, we used this parameter to predict increased platelet count after TIPS placement. METHODS: A total of 161 consecutive patients who underwent TIPS placement entered this retrospective study. The platelet count was measured before, one week after and one month after TIPS placement. Clinically significant thrombocytopenia was defined as platelet count <=100 000. Pre- and post-TIPS PPGs were measured. The velocity of blood flow in the proximal, mid and distal TIPS stent was measured using Doppler ultrasound, and the difference in the highest and lowest measured velocity was entitled flow velocity gradient (FVG), which was considered normal when <=100 cm/s. RESULTS: In 121 patients with pre-TIPS thrombocytopenia, the mean platelet count one week and one month after TIPS placement increased 25.7 x 103 and 35.0 x 103 in 90 patients with PPG<=12 mmHg (P=0.028 and P=0.015), while there was no significant change in platelet count in patients with a PPG >12 mmHg (P=0.098 and P=0.075). Platelets increased significantly when FVG<= 100 cm/s (n=95) vs FVG >100 cm/s (n=26) one week (37.0x103 vs 11.0x103; P = 0.005 vs 0.07) and one month after TIPS placement (17.0x103 vs 5.2x103; P = 0.01 vs 0.21). CONCLUSION: FVG >100 cm/s is not associated with increase in post-TIPS platelet count. On the other hand, findings suggestive of proper TIPS function (FVG <=100 cm/s and PPG<= 12 mmHg) predict a significant increase in post-TIPS platelet count. PMID- 27694620 TI - Single-molecule FRET reveals the pre-initiation and initiation conformations of influenza virus promoter RNA. AB - Influenza viruses have a segmented viral RNA (vRNA) genome, which is replicated by the viral RNA-dependent RNA polymerase (RNAP). Replication initiates on the vRNA 3' terminus, producing a complementary RNA (cRNA) intermediate, which serves as a template for the synthesis of new vRNA. RNAP structures show the 3' terminus of the vRNA template in a pre-initiation state, bound on the surface of the RNAP rather than in the active site; no information is available on 3' cRNA binding. Here, we have used single-molecule Forster resonance energy transfer (smFRET) to probe the viral RNA conformations that occur during RNAP binding and initial replication. We show that even in the absence of nucleotides, the RNAP-bound 3' termini of both vRNA and cRNA exist in two conformations, corresponding to the pre-initiation state and an initiation conformation in which the 3' terminus of the viral RNA is in the RNAP active site. Nucleotide addition stabilises the 3' vRNA in the active site and results in unwinding of the duplexed region of the promoter. Our data provide insights into the dynamic motions of RNA that occur during initial influenza replication and has implications for our understanding of the replication mechanisms of similar pathogenic viruses. PMID- 27694619 TI - FANCI-FANCD2 stabilizes the RAD51-DNA complex by binding RAD51 and protects the 5'-DNA end. AB - The FANCI-FANCD2 (I-D) complex is considered to work with RAD51 to protect the damaged DNA in the stalled replication fork. However, the means by which this DNA protection is accomplished have remained elusive. In the present study, we found that the I-D complex directly binds to RAD51, and stabilizes the RAD51-DNA filament. Unexpectedly, the DNA binding activity of FANCI, but not FANCD2, is explicitly required for the I-D complex-mediated RAD51-DNA filament stabilization. The RAD51 filament stabilized by the I-D complex actually protects the DNA end from nucleolytic degradation by an FA-associated nuclease, FAN1. This DNA end protection is not observed with the RAD51 mutant from FANCR patient cells. These results clearly answer the currently enigmatic question of how RAD51 functions with the I-D complex to prevent genomic instability at the stalled replication fork. PMID- 27694621 TI - Single-molecule FRET studies of the cooperative and non-cooperative binding kinetics of the bacteriophage T4 single-stranded DNA binding protein (gp32) to ssDNA lattices at replication fork junctions. AB - Gene 32 protein (gp32) is the single-stranded (ss) DNA binding protein of the bacteriophage T4. It binds transiently and cooperatively to ssDNA sequences exposed during the DNA replication process and regulates the interactions of the other sub-assemblies of the replication complex during the replication cycle. We here use single-molecule FRET techniques to build on previous thermodynamic studies of gp32 binding to initiate studies of the dynamics of the isolated and cooperative binding of gp32 molecules within the replication complex. DNA primer/template (p/t) constructs are used as models to determine the effects of ssDNA lattice length, gp32 concentration, salt concentration, binding cooperativity and binding polarity at p/t junctions. Hidden Markov models (HMMs) and transition density plots (TDPs) are used to characterize the dynamics of the multi-step assembly pathway of gp32 at p/t junctions of differing polarity, and show that isolated gp32 molecules bind to their ssDNA targets weakly and dissociate quickly, while cooperatively bound dimeric or trimeric clusters of gp32 bind much more tightly, can 'slide' on ssDNA sequences, and exhibit binding dynamics that depend on p/t junction polarities. The potential relationships of these binding dynamics to interactions with other components of the T4 DNA replication complex are discussed. PMID- 27694622 TI - The beta-isoform of BCCIP promotes ADP release from the RAD51 presynaptic filament and enhances homologous DNA pairing. AB - Homologous recombination (HR) is a template-driven repair pathway that mends DNA double-stranded breaks (DSBs), and thus helps to maintain genome stability. The RAD51 recombinase facilitates DNA joint formation during HR, but to accomplish this task, RAD51 must be loaded onto the single-stranded DNA. DSS1, a candidate gene for split hand/split foot syndrome, provides the ability to recognize RPA coated ssDNA to the tumor suppressor BRCA2, which is complexed with RAD51. Together BRCA2-DSS1 displace RPA and load RAD51 onto the ssDNA. In addition, the BRCA2 interacting protein BCCIP normally colocalizes with chromatin bound BRCA2, and upon DSB induction, RAD51 colocalizes with BRCA2-BCCIP foci. Down-regulation of BCCIP reduces DSB repair and disrupts BRCA2 and RAD51 foci formation. While BCCIP is known to interact with BRCA2, the relationship between BCCIP and RAD51 is not known. In this study, we investigated the biochemical role of the beta isoform of BCCIP in relation to the RAD51 recombinase. We demonstrate that BCCIPbeta binds DNA and physically and functionally interacts with RAD51 to stimulate its homologous DNA pairing activity. Notably, this stimulatory effect is not the result of RAD51 nucleoprotein filament stabilization; rather, we demonstrate that BCCIPbeta induces a conformational change within the RAD51 filament that promotes release of ADP to help maintain an active presynaptic filament. Our findings reveal a functional role for BCCIPbeta as a RAD51 accessory factor in HR. PMID- 27694623 TI - Esc2 promotes Mus81 complex-activity via its SUMO-like and DNA binding domains. AB - Replication across damaged DNA templates is accompanied by transient formation of sister chromatid junctions (SCJs). Cells lacking Esc2, an adaptor protein containing no known enzymatic domains, are defective in the metabolism of these SCJs. However, how Esc2 is involved in the metabolism of SCJs remains elusive. Here we show interaction between Esc2 and a structure-specific endonuclease Mus81 Mms4 (the Mus81 complex), their involvement in the metabolism of SCJs, and the effects Esc2 has on the enzymatic activity of the Mus81 complex. We found that Esc2 specifically interacts with the Mus81 complex via its SUMO-like domains, stimulates enzymatic activity of the Mus81 complex in vitro, and is involved in the Mus81 complex-dependent resolution of SCJs in vivo Collectively, our data point to the possibility that the involvement of Esc2 in the metabolism of SCJs is, in part, via modulation of the activity of the Mus81 complex. PMID- 27694624 TI - Adaptive upregulation of DNA repair genes following benzo(a)pyrene diol epoxide protects against cell death at the expense of mutations. AB - A coordinated and faithful DNA damage response is of central importance for maintaining genomic integrity and survival. Here, we show that exposure of human cells to benzo(a)pyrene 9,10-diol-7,8-epoxide (BPDE), the active metabolite of benzo(a)pyrene (B(a)P), which represents a most important carcinogen formed during food preparation at high temperature, smoking and by incomplete combustion processes, causes a prompt and sustained upregulation of the DNA repair genes DDB2, XPC, XPF, XPG and POLH. Induction of these repair factors on RNA and protein level enhanced the removal of BPDE adducts from DNA and protected cells against subsequent BPDE exposure. However, through the induction of POLH the mutation frequency in the surviving cells was enhanced. Activation of these adaptive DNA repair genes was also observed upon B(a)P treatment of MCF7 cells and in buccal cells of human volunteers after cigarette smoking. Our data provide a rational basis for an adaptive response to polycyclic aromatic hydrocarbons, which occurs however at the expense of mutations that may drive cancer formation. PMID- 27694626 TI - Differential cytokine sensitivities of STAT5-dependent enhancers rely on Stat5 autoregulation. AB - Cytokines utilize the transcription factor STAT5 to control cell-specific genes at a larger scale than universal genes, with a mechanistic explanation yet to be supplied. Genome-wide studies have identified putative STAT5-based mammary specific and universal enhancers, an opportunity to investigate mechanisms underlying their differential response to cytokines. We have now interrogated the integrity and function of both categories of regulatory elements using biological and genetic approaches. During lactation, STAT5 occupies mammary-specific and universal cytokine-responsive elements. Following lactation, prolactin levels decline and mammary-specific STAT5-dependent enhancers are decommissioned within 24 h, while universal regulatory complexes remain intact. These differential sensitivities are linked to STAT5 concentrations and the mammary-specific Stat5 autoregulatory enhancer. In its absence, mammary-specific enhancers, but not universal elements, fail to be fully established. Upon termination of lactation STAT5 binding to a subset of mammary enhancers is substituted by STAT3. No STAT3 binding was observed at the most sensitive STAT5 enhancers suggesting that upon hormone withdrawal their chromatin becomes inaccessible. Lastly, we demonstrate that the mammary-enriched transcription factors GR, ELF5 and NFIB associate with STAT5 at sites lacking bona fide binding motifs. This study provides, for the first time, molecular insight into the differential sensitivities of mammary specific and universal cytokine-sensing enhancers.

PMID- 27694627 TI - Genetics of Skeletal Evolution in Unusually Large Mice from Gough Island. AB - Organisms on islands often undergo rapid morphological evolution, providing a platform for understanding mechanisms of phenotypic change. Many examples of evolution on islands involve the vertebrate skeleton. Although the genetic basis of skeletal variation has been studied in laboratory strains, especially in the house mouse Mus musculus domesticus, the genetic determinants of skeletal evolution in natural populations remain poorly understood. We used house mice living on the remote Gough Island-the largest wild house mice on record-to understand the genetics of rapid skeletal evolution in nature. Compared to a mainland reference strain from the same subspecies (WSB/EiJ), the skeleton of Gough Island mice is considerably larger, with notable expansions of the pelvis and limbs. The Gough Island mouse skeleton also displays changes in shape, including elongations of the skull and the proximal vs. distal elements in the limbs. Quantitative trait locus (QTL) mapping in a large F2 intercross between Gough Island mice and WSB/EiJ reveals hundreds of QTL that control skeletal dimensions measured at 5, 10, and/or 16 weeks of age. QTL exhibit modest, mostly additive effects, and Gough Island alleles are associated with larger skeletal size at most QTL. The QTL with the largest effects are found on a few chromosomes and affect suites of skeletal traits. Many of these loci also colocalize with QTL for body weight. The high degree of QTL colocalization is consistent with an important contribution of pleiotropy to skeletal evolution. Our results provide a rare portrait of the genetic basis of skeletal evolution in an island population and position the Gough Island mouse as a model system for understanding mechanisms of rapid evolution in nature. PMID- 27694629 TI - Zika virus (ZIKV) infection related with immune thrombocytopenic purpura (ITP) exacerbation and antinuclear antibody positivity. AB - A 30-year-old Colombian woman with past history of immune thrombocytopenia (ITP) presented to the emergency room with two days of global headache, arthralgia, myalgia, and low level fever and generalized erythematous rash. Platelets dropped to 9 * 109/L (fourth day of symptoms) without hemorrhagic manifestations but recovered to 30 * 109/L in 24 hours (fifth day). Dengue virus infection, as well as other viral infections, was ruled out. Zika virus (ZIKV) was evaluated in serum and urine samples by real-time reverse-transcriptase polymerase chain reaction (genomic regions within E protein and NS2b protein). Urine sample was positive and serum sample negative for ZIKV, confirming a recent ZIKV infection with urinary tract virus excretion at 7th day after disease onset. To our knowledge this is the first description of a case of severe immune thrombocytopenia exacerbation and antinuclear antibody positivity induced by ZIKV infection. PMID- 27694630 TI - Deciphering systemic lupus erythematosus-associated serum biomarkers reflecting apoptosis and disease activity. AB - Systemic lupus erythematosus (SLE) is a severe chronic inflammatory autoimmune connective tissue disease. Despite major efforts, SLE remains a poorly understood disease with unpredictable course, unknown etiology and complex pathogenesis. Apoptosis combined with deficiency in clearing apoptotic cells is an important etiopathogenic event in SLE, which could contribute to the increased load of potential autoantigen(s); however, the lack of disease-specific protein signatures deciphering SLE and the underlying biological processes is striking and represents a key limitation. In this retrospective pilot study, we explored the immune system as a specific sensor for disease, in order to advance our understanding of SLE. To this end, we determined multiplexed serum protein expression profiles of crude SLE serum samples, using antibody microarrays. The aim was to identify differential immunoprofiles, or snapshots of the immune response modulated by the disease, reflecting apoptosis, a key process in the etiology of SLE and disease activity. The results showed that multiplexed panels of SLE-associated serum biomarkers could be decoded, in particular reflecting disease activity, but potentially the apoptosis process as well. While the former biomarkers could display a potential future use for prognosis, the latter biomarkers might help shed further light on the apoptosis process taking place in SLE. PMID- 27694631 TI - Review of Naturally Occurring Intussusception in Young Children in the WHO African Region prior to the Era of Rotavirus Vaccine Utilization in the Expanded Programme of Immunization. AB - Rotavirus vaccines, Rotarix and RotaTeq, are increasingly being introduced in national immunization programmes in Africa to prevent severe dehydrating acute gastroenteritis. A low-level risk of intussusception has been associated with rotavirus vaccines. We reviewed published data on intussusception in children <2 years of age in Africa. PubMed electronic database search was used to retrieve papers published on intussusception. The search was further refined to identify surveillance reports and case series conducted from 1980 to 2014, with at least 25 cases. The initial search identified 34 studies, and the refined search yielded 16. Intussusception occurred naturally in infants 2-4 months and peaked around 5-8 months of age. Delayed presentation was common and required surgical intervention in 87% (1008 of 1158) of cases with a high CFR, 10-33.7%. In African children, intussusception has been reported infrequently at a young age when the first dose of rotavirus vaccine is administered.

PMID- 27694633 TI - A Randomized, Controlled, Observer-Blinded Phase 1 Study of the Safety and Immunogenicity of a Respiratory Syncytial Virus Vaccine With or Without Alum Adjuvant. AB - BACKGROUND: Respiratory syncytial virus (RSV) is a leading cause of childhood bronchiolitis and pneumonia, particularly in early infancy. Immunization of pregnant women could boost preexisting immune responses, providing passive protection to newborns through placental transfer of anti-RSV antibody. METHODS: In this first-in-humans clinical trial of a purified recombinant RSV protein F vaccine engineered to preferentially maintain prefusion conformation (RSV-PreF), 128 healthy men 18-44 years old were randomized to one dose of a RSV-PreF vaccine containing 10, 30, or 60 ug of RSV-PreF antigen, with or without alum adjuvant, or control, and followed for one year for safety and immunogenicity outcomes. RESULTS: Injection site pain was the most common adverse event, reported by up to 81.3% of participants. The highest RSV neutralizing antibody responses were in the 30 ug RSV-PreF/alum, 60 ug RSV-PreF/alum, and 60 ug RSV-PreF/nonadjuvant groups. Responses were evident on day 7, and 30 days after vaccination these participants had RSV-A neutralizing antibody titers of >=1:512, and >70% had titers of 1:1024, with titers increasing by 3.2-4.9 fold. Responses remained high on day 60 but waned on days 180 and 360. CONCLUSIONS: The RSV-PreF vaccine elicited rapid RSV neutralizing antibody responses in healthy young men, with an acceptable adverse event profile. PMID- 27694636 TI - Inverse associations between cord vitamin D and attention deficit hyperactivity disorder symptoms: A child cohort study. AB - OBJECTIVE: To examine the association between cord 25-hydroxyvitamin D2+3 (25(OH)D) and attention deficit hyperactivity disorder symptoms in toddlers, using Child Behaviour Checklist for ages 1.5-5. METHOD: In a population-based birth cohort, a Child Behaviour Checklist for ages 1.5-5 questionnaire was returned from parents of 1233 infants with mean age 2.7 (standard deviation 0.6) years. Adjusted associations between cord 25(OH)D and Child Behaviour Checklist based attention deficit hyperactivity disorder problems were analysed by multiple regression. Results The median cord 25(OH)D was 44.1 (range: 1.5-127.1) nmol/L. Mean attention deficit hyperactivity disorder problem score was 2.7 (standard deviation 2.1). In adjusted analyses, cord 25(OH)D levels >25 nmol/L and >30 nmol/L were associated with lower attention deficit hyperactivity disorder scores compared to levels ?25 nmol/L ( p = 0.035) and ?30 nmol/L ( p = 0.043), respectively. The adjusted odds of scoring above the 90th percentile on the Child Behaviour Checklist-based attention deficit hyperactivity disorder problem scale decreased by 11% per 10 nmol/L increase in cord 25(OH)D. CONCLUSION: An inverse association between cord 25(OH)D and attention deficit hyperactivity disorder symptoms in toddlers was found, suggesting a protective effect of prenatal vitamin D. PMID- 27694635 TI - Muramyl peptides activate innate immunity conjointly via YB1 and NOD2. AB - Bacterial cell wall muramyl dipeptide (MDP) and glucosaminyl-MDP (GMDP) are potent activators of innate immunity. Two receptor targets, NOD2 and YB1, have been reported; we investigated potential overlap of NOD2 and YB1 pathways. Separate knockdown of NOD2 and YB1 demonstrates that both contribute to GMDP induction of NF-kappaB expression, a marker of innate immunity, although excess YB1 led to induction in the absence of NOD2. YB1 and NOD2 co-migrated on sucrose gradient centrifugation, and GMDP addition led to the formation of higher molecular mass complexes containing both YB1 and NOD2. Co-immunoprecipitation demonstrated a direct interaction between YB1 and NOD2, a major recombinant fragment of NOD2 (NACHT-LRR) bound to YB1, and complex formation was stimulated by GMDP. We also report subcellular colocalization of NOD2 and YB1. Although YB1 may have other binding partners in addition to NOD2, maximal innate immunity activation by muramyl peptides is mediated via an interaction between YB1 and NOD2. PMID- 27694637 TI - The impact of potentially traumatic events on the mental health of males who have served in the military: Findings from the Australian National Survey of Mental Health and Wellbeing. AB - OBJECTIVE: The study investigated the impact of potentially traumatic events on mental health outcomes among males who had ever served in the Australian Defence Force. METHOD: Data from a nationally representative household survey of Australian residents, the 2007 National Survey of Mental Health and Wellbeing, were used for this study. RESULTS: Compared with community members, Australian Defence Force males were significantly more likely to have experienced not only deployment and other war-like events but also accidents or other unexpected events, and trauma to someone close. For non-deployed males, Australian Defence Force members were at increased risk of accidents or other unexpected events compared to community members. After controlling for the effect of potentially traumatic events that were more prevalent among all Australian Defence Force members, the increased risk of mental disorders among Australian Defence Force members was no longer evident. For non-deployed males, Australian Defence Force and community members were at comparable risk of poor mental health outcomes. A significant minority of Australian Defence Force members had onset of a mental disorder prior to their first deployment. CONCLUSIONS: Deployment and other potentially traumatic events among Australian Defence Force members can help to explain their increased vulnerability to mental disorders compared with community members. Providers should routinely enquire about a range of potentially traumatic events among serving and ex-serving military personnel. PMID- 27694638 TI - Intrinsic brain abnormalities in young healthy adults with childhood trauma: A resting-state functional magnetic resonance imaging study of regional homogeneity and functional connectivity. AB - OBJECTIVE: Childhood trauma confers great risk for the development of multiple psychiatric disorders; however, the neural basis for this association is still unknown. The present resting-state functional magnetic resonance imaging study aimed to detect the effects of childhood trauma on brain function in a group of young healthy adults. METHODS: In total, 24 healthy individuals with childhood trauma and 24 age- and sex-matched adults without childhood trauma were recruited. Each participant underwent resting-state functional magnetic resonance imaging scanning. Intra-regional brain activity was evaluated by regional homogeneity method and compared between groups. Areas with altered regional homogeneity were further selected as seeds in subsequent functional connectivity analysis. Statistical analyses were performed by setting current depression and anxiety as covariates. RESULTS: Adults with childhood trauma showed decreased regional homogeneity in bilateral superior temporal gyrus and insula, and the right inferior parietal lobule, as well as increased regional homogeneity in the right cerebellum and left middle temporal gyrus. Regional homogeneity values in the left middle temporal gyrus, right insula and right cerebellum were correlated with childhood trauma severity. In addition, individuals with childhood trauma also exhibited altered default mode network, cerebellum-default mode network and insula-default mode network connectivity when the left middle temporal gyrus, right cerebellum and right insula were selected as seed area, respectively. CONCLUSION: The present outcomes suggest that childhood trauma is associated with disturbed intrinsic brain function, especially the default mode network, in adults even without psychiatric diagnoses, which may mediate the relationship between childhood trauma and psychiatric disorders in later life. PMID- 27694639 TI - Improving access to primary mental health care for Australian children. AB - OBJECTIVE: This study examines the uptake by children aged predominantly 0-11 years of an Australian primary mental health service - the Access to Allied Psychological Services programme - which began in 2001. In particular, it considers access to, and use of, the child component of Access to Allied Psychological Services, the Child Mental Health Service, introduced in 2010. METHOD: Using routinely collected programme data from a national minimum dataset and regional population data, we conducted descriptive and regression analysis to examine programme uptake, predictors of service reach and consumer- and treatment based characteristics of service. RESULTS: Between 2003 and 2013, 18,631 referrals for children were made and 75,178 sessions were scheduled via Access to Allied Psychological Services, over 50% of which were via the Child Mental Health Service in its first 3 years of operation. The rate of referrals for children to the Child Mental Health Service was associated with the rate of Access to Allied Psychological Services referrals for consumers aged 12+ years. CONCLUSIONS: The Child Mental Health Service has increased services provided within the Access to Allied Psychological Services programme for children with emotional and behavioural issues and their families, and is potentially filling a service gap in the area of prevention and early intervention for children who have significant levels of need but are unable to access other mental health services. Our findings are policy-relevant for other developed countries with a similar primary mental health care system that are considering means of improving service access by children.

PMID- 27694642 TI - Enteral Formulas in Nutrition Support Practice: Is There a Better Choice for Your Patient? AB - Over the past few decades, the number of enteral formulas for use in hospitalized, critically ill, and home enteral patients has dramatically increased. Several enteral nutrition (EN) formula categories exist, which makes it challenging for clinicians to sort through the product claims and find the appropriate formula for the patient. Many formulas are available within each category, some of which may be significantly different from one another. Numerous systematic reviews of existing research and clinical practice guidelines evaluate the use of specialty formulas. This review aims to examine the differences in various enteral formula categories, identify applications in clinical practice, and evaluate the existing evidence and guideline recommendations for use of specific types of enteral formulas. PMID- 27694643 TI - Effect of sorghum consumption on health outcomes: a systematic review. AB - CONTEXT: Sorghum, an ancient grain originating in Africa, may have health protective properties that could encourage its consumption among those who do not traditionally consume it. OBJECTIVE: The aim of this systematic review was to evaluate the health effects associated with the consumption of sorghum among humans. DATA SOURCES: Academic databases were searched for relevant studies published between 1985 and November 2015. STUDY SELECTION: Nineteen studies -13 interventional and 6 observational - were identified for inclusion. DATA EXTRACTION: Participant characteristics, study country, health outcomes, main findings, and study quality were reported. Interventional and observational studies were summarized separately. RESULTS: Studies were divided into those that investigated the effect of sorghum on chronic disease and those that investigated other effects of sorghum on health. There was evidence that the consumption of sorghum attenuated blood glucose responses and decreased the expression of markers of oxidative stress. Sorghum was also observed to be a suitable ingredient for the formulation of oral rehydration solutions and showed potential for use as a medical adjunct to boost immune responses in HIV-positive patients CONCLUSIONS: The implication is that sorghum may have attributes superior to those of other staple grains, indicating its potential for innovative uses in commercial foods. More work is required to elucidate the health effects of sorghum when consumed by population groups that have not been traditional consumers of the grain. PMID- 27694644 TI - Transition in ADHD: attention to the lifespan. AB - OBJECTIVES: This paper reviews the importance of transition to adult services for young people with ADHD. METHOD: Different models are described and evidence sought for their effectiveness in clinical practice. RESULTS: Models of care for children with ADHD include specialised mental health services, individual paediatricians and child and adolescent psychiatrists. Although it might be expected that transition would be to equivalent adult teams or specialists, studies have shown that transition may not run smoothly, and the adult services are frequently inadequate. This may result in attrition from treatment or discharge to the general practitioner. CONCLUSIONS: Adult mental health services for transitioning young people with ADHD are under-resourced. The way forward may be a generic ADHD specialist or service, treating ADHD across the lifespan and avoiding the need for transition. PMID- 27694645 TI - Alcohol, drug and related health and wellbeing issues among young people completing an online screen. AB - OBJECTIVE: Despite high levels of alcohol use, drug use and risky behaviors, rates of help-seeking amongst young people are typically low. This study explored the profile of young people (under the age of 25 years) completing an online screen, assessing substance use problem severity and wellbeing in comparison with adults completing the same screen, so as to inform development of better targeted approaches for this in-need population. METHODS: Between 2012 and 2014, an online alcohol and drug screen was promoted across Australia on a national online counseling service. The screen assessed severity of substance use, mental health and wellbeing. RESULTS: A total of 2939 screens were completed between December 2012 and May 2014, with 18% completed by young people. Young people reported a high severity of substance use problems (44% reported likely drug dependence) and reported significantly poorer mental health and wellbeing than adults completing the screen. This suggests that there is a population of young people in need of support who could be initially engaged through online screening. CONCLUSIONS: Online screening should be a key component of engagement strategies for adolescent and early adult help-seeking. PMID- 27694646 TI - The conundrum of hanging points in correctional facilities. AB - OBJECTIVE: We aimed to explore aspects of the removal of hanging points from correctional facilities. CONCLUSION: An argument can be made that individuals have a right to die/suicide. The United Nations holds that except for freedom of movement, prisoners have the same rights as non-prisoners. The rights of the individual and the duty of many custodial institutions are in conflict. This introduces a conundrum; when all hanging points are removed from correctional facilities, prisoners without mental disorder, but with a sustained wish to die, will not be able to achieve that end, while non-prisoners will be well able to do so. PMID- 27694647 TI - Diabetes Dictating Policy: An Editorial Commemorating World Health Day 2016. AB - The 21st century is an era of great challenge for humankind; we are combating terrorism, climate change, poverty, human rights issues and last but not least non-communicable diseases (NCDs). The burden of the latter has become so large that it is being recognized by world leaders globally as an area that it is in need of much greater attention. In light of this concern, the World Health Organization (WHO) dedicated this year's World Health Day (held on April 7, 2016) to raising international awareness on diabetes, the fastest growing NCD in the world. This editorial is an account of the macro politics in place for fighting diabetes, both internationally and nationally. PMID- 27694648 TI - Health Departments' Engagement in Emergency Preparedness Activities: The Influence of Health Informatics Capacity. AB - BACKGROUND: Local health departments (LHDs) operate in a complex and dynamic public health landscape, with changing demands on their emergency response capacities. Informatics capacities might play an instrumental role in aiding LHDs emergency preparedness. This study aimed to explore the extent to which LHDs' informatics capacities are associated with their activity level in emergency preparedness and to identify which health informatics capacities are associated with improved emergency preparedness. METHODS: We used the 2013 National Profile of LHDs study to perform Poisson regression of emergency preparedness activities. RESULTS: Only 38.3% of LHDs participated in full-scale exercises or drills for an emergency in the 12 months period prior to the survey, but a much larger proportion provided emergency preparedness training to staff (84.3%), and/or participated in tabletop exercises (76.4%). Our multivariable analysis showed that after adjusting for several resource-related LHD characteristics, LHDs with more of the 6 information systems still tend to have slightly more preparedness activities. In addition, having a designated emergency preparedness coordinator, and having one or more emergency preparedness staff were among the most significant factors associated with LHDs performing more emergency preparedness activities. CONCLUSION: LHDs might want to utilize better health information systems and information technology tools to improve their activity level in emergency preparedness, through improved information dissemination, and evidence collection. PMID- 27694649 TI - Planning and Budgeting for Nutrition Programs in Tanzania: Lessons Learned From the National Vitamin A Supplementation Program. AB - BACKGROUND: Micronutrient deficiency in Tanzania is a significant public health problem, with vitamin A deficiency (VAD) affecting 34% of children aged 6 to 59 months. Since 2007, development partners have worked closely to advocate for the inclusion of twice-yearly vitamin A supplementation and deworming (VASD) activities with budgets at the subnational level, where funding and implementation occur. As part of the advocacy work, a VASD planning and budgeting tool (PBT) was developed and is used by district officials to justify allocation of funds. Helen Keller International (HKI) and the Tanzania Food and Nutrition Centre (TFNC) conduct reviews of VASD funds and health budgets annually in all districts to monitor the impact of advocacy efforts. This paper presents the findings of the fiscal year (FY) 2010 district budget annual review. The review was intended to answer the following questions regarding district-level funding: (1) how many funds were allocated to nutrition-specific activities in FY 2010? (2) how many funds were allocated specifically to twice-yearly VASD activities in FY 2010? and (3) how have VASD funding allocations changed over time? METHODS: Budgets from all 133 districts in Tanzania were accessed, reviewed and documented to identify line item funds allocated for VASD and other nutrition activities in FY 2010. Retrospective data from prior annual reviews for VASD were used to track trends in funding. The data were collected using specific data forms and then transcribed into an excel spreadsheet for analysis. RESULTS: The total funds allocated in Tanzania's districts in FY 2010 amounted to US$1.4 million of which 92% were for VASD. Allocations for VASD increased from US$0.387 million to US$1.3 million between FY 2005 and FY 2010. Twelve different nutrition activities were identified in budgets across the 133 districts. Despite the increased trend, the percentage of districts allocating sufficient funds to implement VAS (as defined by cost per child) was just 21%. DISCUSSION: District-driven VAS funding in Tanzania continues to be allocated by districts consistently, although adequacy of funding is a concern. However, regular administrative data point to fairly high and consistent coverage rates for VAS across the country (over 80% over the last 10 years). Although this analysis may have omitted some nutrition-specific funding not identified in district budget data, it represents a reliable reflection of the nutrition funding landscape in FY 2010. For this year, total district nutrition allocations add up to only 2% of the amount needed to implement nutrition services at scale according to Tanzania's National Nutrition Strategy Implementation Plan. CONCLUSION: VASD advocacy and planning support at the district level has succeeded in ensuring district allocations for the program. To promote sustainable implementation of other nutrition interventions in Tanzania, more funds must be allocated and guidance must be accompanied by tools that enable planning and budgeting at the district level.

AB - BACKGROUND: Recent British National Health Service (NHS) reforms, in response to austerity and alleged 'health tourism,' could impose additional barriers to healthcare access for non-European Economic Area (EEA) migrants. This study explores policy reform challenges and implications, using excerpts from the perspectives of non-EEA migrants and health advocates in London. METHODS: A qualitative study design was selected. Data were collected through document review and 22 in-depth interviews with non-EEA migrants and civil-society organisation representatives. Data were analysed thematically using the NHS principles. RESULTS: The experiences of those 'vulnerable migrants' (ie, defined as adult non-EEA asylum-seekers, refugees, undocumented, low-skilled, and trafficked migrants susceptible to marginalised healthcare access) able to access health services were positive, with healthcare professionals generally demonstrating caring attitudes. However, general confusion existed about entitlements due to recent NHS changes, controversy over 'health tourism,' and challenges registering for health services or accessing secondary facilities. Factors requiring greater clarity or improvement included accessibility, communication, and clarity on general practitioner (GP) responsibilities and migrant entitlements. CONCLUSION: Legislation to restrict access to healthcare based on immigration status could further compromise the health of vulnerable individuals in Britain. This study highlights current challenges in health services policy and practice and the role of non-governmental organizations (NGOs) in healthcare advocacy (eg, helping the voices of the most vulnerable reach policy-makers). Thus, it contributes to broadening national discussions and enabling more nuanced interpretation of ongoing global debates on immigration and health. PMID- 27694651 TI - Politics, Power, Poverty and Global Health: Systems and Frames. AB - Striking disparities in access to healthcare and in health outcomes are major characteristics of health across the globe. This inequitable state of global health and how it could be improved has become a highly popularized field of academic study. In a series of articles in this journal the roles of power and politics in global health have been addressed in considerable detail. Three points are added here to this debate. The first is consideration of how the use of definitions and common terms, for example 'poverty eradication,' can mask full exposure of the extent of rectification required, with consequent failure to understand what poverty eradication should mean, how this could be achieved and that a new definition is called for. Secondly, a criticism is offered of how the term 'global health' is used in a restricted manner to describe activities that focus on an anthropocentric and biomedical conception of health across the world. It is proposed that the discourse on 'global health' should be extended beyond conventional boundaries towards an ecocentric conception of global/planetary health in an increasingly interdependent planet characterised by a multitude of interlinked crises. Finally, it is noted that the paucity of workable strategies towards achieving greater equity in sustainable global health is not so much due to lack of understanding of, or insight into, the invisible dimensions of power, but is rather the outcome of seeking solutions from within belief systems and cognitive biases that cannot offer solutions. Hence the need for a new framing perspective for global health that could reshape our thinking and actions.

Comment on "Understanding the Role of Public Administration in Implementing Action on the Social Determinants of Health and Health Inequities". AB - Carey and Friel suggest that we turn to knowledge developed in the field of public administration, especially new public governance, to better understand the process of implementing health in all policies (HiAP). In this commentary, I claim that theories from the policy studies bring a broader view of the policy process, complementary to that of new public governance. Drawing on the policy studies, I argue that time and ideas matter to HiAP implementation, alongside with interests and institutions. Implementing HiAP is a complex process considering that it requires the involvement and coordination of several policy sectors, each with their own interests, institutions and ideas about the policy. Understanding who are the actors involved from the various policy sectors concerned, what context they evolve in, but also how they own and frame the policy problem (ideas), and how this has changed over time, is crucial for those involved in HiAP implementation so that they can relate to and work together with actors from other policy sectors.

AB - Notwithstanding a century of prohibition, marijuana is the most widely used illicit substance in Canada. Due to the growing public acceptance of recreational marijuana use and ineffectiveness of the existing control system in Canada, the issue surrounding legalizing this illicit drug has received considerable public and political attentions in recent years. Consequently, the newly elected Liberal Government has formally announced that Canada will introduce legislation in the spring of 2017 to start legalizing and regulating marijuana. This editorial aims to provide a brief overview on potential economic, social, and public health impacts of legal marijuana in Canada. The legalization could increase tax revenue through the taxation levied on marijuana products and could also allow the Government to save citizens' tax dollars currently being spent on prohibition enforcement. Moreover, legalization could also remove the criminal element from marijuana market and reduce the size of Canada's black market and its consequences for the society. Nevertheless, it may also lead to some public health problems, including increasing in the uptake of the drug, accidents and injuries. The legalization should be accompanied with comprehensive strategies to keep the drug out of the hands of minors while increasing awareness and knowledge on harmful effects of the drug. In order to get better insights on how to develop an appropriate framework to legalize marijuana, Canada should closely watch the development in the neighboring country, the United States, where some of its states viz, Colorado, Oregon, Washington, and Alaska have already legalized recreational use of marijuana.

PMID- 27694659 TI - Assessing Patient Participation in Health Policy Decision-Making in Cyprus. AB - Although the importance of patient participation in the design and evaluation of health programs and services is well-documented, there is scarcity of research with regard to patient association (PA) participation in health policy decision making processes. To this end, the present study aimed to validate further a previously developed instrument as well as to investigate the degree of PA participation in health policy decision-making in Cyprus. A convenient sample of 114 patients-members of patients associations took part in the study. Participants were recruited from an umbrella organization, the Pancyprian Federation of Patient Associations and Friends (PFPA). PA participation in health policy decision-making was assessed with the Health Democracy Index (HDI), an original 8-item tool. To explore its psychometric properties, Cronbach alpha was computed as regards to its internal consistency, while its convergent validity was tested against a self-rated question enquiring about the degree of PA participation in health policy decision-making. The findings revealed that the HDI has good internal consistency and convergent validity. Furthermore, PAs were found to participate more in consultations in health-related organizations and the Ministry of Health (MoH) as well as in reforms or crucial decisions in health policy. Lower levels were documented with regard to participation in hospital boards, ethics committees in clinical trials and health technology assessment (HTA) procedures. Overall, PA participation levels were found to be lower than the mid-point of the scale. Targeted interventions aiming to facilitate patients' involvement in health policy decision-making processes and to increase its impact are greatly needed in Cyprus. PMID- 27694660 TI - Motivation and Retention of Physicians in Primary Healthcare Facilities: A Qualitative Study From Abbottabad, Pakistan. AB - BACKGROUND: Workforce motivation and retention is important for the functionality and quality of service delivery in health systems of developing countries. Despite huge primary healthcare (PHC) infrastructure, Pakistan's health indicators are not impressive; mainly because of under-utilization of facilities and low patient satisfaction. One of the major underlying issues is staff absenteeism. The study aimed to identify factors affecting retention and motivation of doctors working in PHC facilities of Pakistan. METHODS: An exploratory study was conducted in a rural district in Khyber Puktunkhwa (KP) province, in Pakistan. A conceptual framework was developed comprising of three organizational, individual, and external environmental factors. Qualitative research methods comprising of semi-structured interviews with doctors working in basic health units (BHUs) and in-depth interviews with district and provincial government health managers were used. Document review of postings, rules of business and policy actions was also conducted. Triangulation of findings was carried out to arrive at the final synthesis. RESULTS: Inadequate remuneration, unreasonable facilities at residence, poor work environment, political interference, inadequate supplies and medical facilities contributed to lack of motivation among both male and female doctors. The physicians accepted government jobs in BHUs with a belief that these jobs were more secure, with convenient working hours. Male physicians seemed to be more motivated because they faced less challenges than their female counterparts in BHUs especially during relocations. Overall, the organizational factors emerged as the most significant whereby human resource policy, career growth structure, performance appraisal and monetary benefits played an important role. Gender and marital status of female doctors was regarded as most important individual factor affecting retention and motivation of female doctors in BHUs. CONCLUSION: Inadequate remuneration, unreasonable facilities at residence, poor work environment, political interference, inadequate supplies, and medical facilities contributed to lack of motivation in physicians in our study. Our study advocates that by addressing the retention and motivation challenges, service delivery can be made more responsive to the patients and communities in Pakistan and other similar settings. PMID- 27694662 TI - The Trans-Pacific Partnership: Is It Everything We Feared for Health? AB - BACKGROUND: Negotiations surrounding the Trans-Pacific Partnership (TPP) trade and investment agreement have recently concluded. Although trade and investment agreements, part of a broader shift to global economic integration, have been argued to be vital to improved economic growth, health, and general welfare, these agreements have increasingly come under scrutiny for their direct and indirect health impacts. METHODS: We conducted a prospective health impact analysis to identify and assess a selected array of potential health risks of the TPP. We adapted the standard protocol for Health impact assessments (HIAs) (screening, scoping, and appraisal) to our aim of assessing potential health risks of trade and investment policy, and selected a health impact review methodology. This methodology is used to create a summary estimation of the most significant impacts on health of a broad policy or cluster of policies, such as a comprehensive trade and investment agreement. RESULTS: Our analysis shows that there are a number of potentially serious health risks associated with the TPP, and details a range of policy implications for the health sector. Of particular focus are the potential implications of changes to intellectual property rights (IPRs), sanitary and phytosanitary measures (SPS), technical barriers to trade (TBT), investor-state dispute settlement (ISDS), and regulatory coherence provisions on a range of issues, including access to medicines and health services, tobacco and alcohol control, diet-related health, and domestic health policy-making. CONCLUSION: We provide a list of policy recommendations to mitigate potential health risks associated with the TPP, and suggest that broad public consultations, including on the health risks of trade and investment agreements, should be part of all trade negotiations. PMID- 27694661 TI - Developing Leadership in Managers to Facilitate the Implementation of National Guideline Recommendations: A Process Evaluation of Feasibility and Usefulness. AB - BACKGROUND: Previous research supports the claim that managers are vital players in the implementation of clinical practice guidelines (CPGs), yet little is known about interventions aiming to develop managers' leadership in facilitating implementation. In this pilot study, process evaluation was employed to study the feasibility and usefulness of a leadership intervention by exploring the intervention's potential to support managers in the implementation of national guideline recommendations for stroke care in outpatient rehabilitation. METHODS: Eleven senior and frontline managers from five outpatient stroke rehabilitation centers participated in a four-month leadership intervention that included workshops, seminars, and teleconferences. The focus was on developing knowledge and skills to enhance the implementation of CPG recommendations, with a particular focus on leadership behaviors. Each dyad of managers was assigned to develop a leadership plan with specific goals and leadership behaviors for implementing three rehabilitation recommendations. Feasibility and usefulness were explored through observations and interviews with the managers and staff members prior to the intervention, and then one month and one year after the intervention. RESULTS: Managers considered the intervention beneficial, particularly the participation of both senior and frontline managers and the focus on leadership knowledge and skills for implementing CPG recommendations. All the managers developed a leadership plan, but only two units identified goals specific to implementing the three stroke rehabilitation recommendations. Of these, only one identified leadership behaviors that support implementation. CONCLUSION: Managers found that the intervention was delivered in a feasible way and appreciated the focus on leadership to facilitate implementation. However, the intervention appeared to have limited impact on managers' behaviors or clinical practice at the units. Future interventions directed towards managers should have a stronger focus on developing leadership skills and behaviors to tailor implementation plans and support implementation of CPG recommendations. PMID- 27694663 TI - Priority Setting Meets Multiple Streams: A Match to Be Further Examined? Comment on "Introducing New Priority Setting and Resource Allocation Processes in a Canadian Healthcare Organization: A Case Study Analysis Informed by Multiple Streams Theory. AB - With demand for health services continuing to grow as populations age and new technologies emerge to meet health needs, healthcare policy-makers are under constant pressure to set priorities, ie, to make choices about the health services that can and cannot be funded within available resources. In a recent paper, Smith et al apply an influential policy studies framework - Kingdon's multiple streams approach (MSA) - to explore the factors that explain why one health service delivery organization adopted a formal priority setting framework (in the form of programme budgeting and marginal analysis [PBMA]) to assist it in making priority setting decisions. MSA is a theory of agenda-setting, ie, how it is that different issues do or do not reach a decision-making point. In this paper, I reflect on the use of the MSA framework to explore priority setting processes and how the framework might be applied to similar cases in future. PMID- 27694664 TI - HTA - Algorithm or Process? Comment on "Expanded HTA: Enhancing Fairness and Legitimacy". AB - Daniels, Porteny and Urrutia et al make a good case for the idea that that public decisions ought to be made not only "in the light of" evidence but also "on the basis of" budget impact, financial protection and equity. Health technology assessment (HTA) should, they say, be accordingly expanded to consider matters additional to safety and cost-effectiveness. They also complain that most HTA reports fail to develop ethical arguments and generally do not even mention ethical issues. This comment argues that some of these defects are more apparent than real and are not inherent in HTA - as distinct from being common characteristics found in poorly conducted HTAs. More generally, HTA does not need "extension" since (1) ethical issues are already embedded in HTA processes, not least in their scoping phases, and (2) HTA processes are already sufficiently flexible to accommodate evidence about a wide range of factors, and will not need fundamental change in order to accommodate the new forms of decision-relevant evidence about distributional impact and financial protection that are now starting to emerge. HTA and related techniques are there to support decision makers who have authority to make decisions. Analysts like us are there to support and advise them (and not to assume the responsibilities for which they, and not we, are accountable). The required quality in HTA then becomes its effectiveness as a means of addressing the issues of concern to decision-makers. What is also required is adherence by competent analysts to a standard template of good analytical practice. The competencies include not merely those of the usual disciplines (particularly biostatistics, cognitive psychology, health economics, epidemiology, and ethics) but also the imaginative and interpersonal skills for exploring the "real" question behind the decision-maker's brief (actual or postulated) and eliciting the social values that necessarily pervade the entire analysis. The product of such exploration defines the authoritative scope of an HTA.

AB - Governance in health is cited as one of the key factors in balancing the concerns of the government and public sector with the interests of civil society/private players, but often remains poorly described and operationalized. Richard Saltman and Antonio Duran look at two aspects in the search for new provider models in a context of health markets signalling liberalisation: (i) the role of the government to balance public and private interests and responsibilities in delivering care through modernised governance arrangements, and (ii) the finding that operational complexities may hinder well-designed provider governance models, unless governance reflects country-specific realities. This commentary builds on the discussion by Saltman and Duran, and argues that the concept of governance needs to be clearly defined and operationalized in order to be helpful for policy debate as well as for the development of an applicable framework for performance improvement. It provides a working definition of governance and includes a reflection on the prevailing cultural norms in an organization or society upon which any governance needs to be build. It proposes to explore whether the "evidence-based governance" concept can be introduced to generate knowledge about innovative and effective governance models, and concludes that studies similar to the one by Saltman and Duran can inform this debate.

AB - Recognizing the advantages of primary care as a means of improving the entire health system, this text comments on reforms of publicly funded primary health centers, and the rapid development of private for-profit providers in Sweden. Many goals and expectations are connected to such reforms, which equally require critical analyses of scarce resources, professional trust/motivation and business logic in the wake of freedom and control of ownership and management. In line with Saltman and Duran, this article calls for research and a methodologically developed approach to capture everyday practice in-depth and how regulation, market incentives and patient demands are met by professionals and primary care leaders. PMID- 27694667 TI - Needed: Global Collaboration for Comparative Research on Cities and Health. AB - Over half of the world's population lives in cities and United Nations (UN) demographers project an increase of 2.5 billion more urban dwellers by 2050. Yet there is too little systematic comparative research on the practice of urban health policy and management (HPAM), particularly in the megacities of middle income and developing nations. We make a case for creating a global database on cities, population health and healthcare systems. The expenses involved in data collection would be difficult to justify without some review of previous work, some agreement on indicators worth measuring, conceptual and methodological considerations to guide the construction of the global database, and a set of research questions and hypotheses to test. We, therefore, address these issues in a manner that we hope will stimulate further discussion and collaboration. PMID- 27694668 TI - What Can We Learn About the Processes of Regulation of Tuberculosis Medicines From the Experiences of Health Policy and System Actors in India, Tanzania, and Zambia? AB - BACKGROUND: The unregulated availability and irrational use of tuberculosis (TB) medicines is a major issue of public health concern globally. Governments of many low- and middle-income countries (LMICs) have committed to regulating the quality and availability of TB medicines, but with variable success. Regulation of TB medicines remains an intractable challenge in many settings, but the reasons for this are poorly understood. The objective of this paper is to elaborate processes of regulation of quality and availability of TB medicines in three LMICs - India, Tanzania, and Zambia - and to understand the factors that constrain and enable these processes. METHODS: We adopted the action-centred approach of policy implementation analysis that draws on the experiences of relevant policy and health system actors in order to understand regulatory processes. We drew on data from three case studies commissioned by the World Health Organization (WHO), on the regulation of TB medicines in India, Tanzania, and Zambia. Qualitative research methods were used, including in-depth interviews with 89 policy and health system actors and document review. Data were organized thematically into accounts of regulators' authority and capacity; extent of policy implementation; and efficiency, transparency, and accountability. RESULTS: In India, findings included the absence of a comprehensive policy framework for regulation of TB medicines, constraints of authority and capacity of regulators, and poor implementation of prescribing and dispensing norms in the majority private sector. Tanzania had a policy that restricted import, prescribing and dispensing of TB medicines to government operators. Zambia procured and dispensed TB medicines mainly through government services, albeit in the absence of a single policy for restriction of medicines. Three cross-cutting factors emerged as crucially influencing regulatory processes - political and stakeholder support for regulation, technical and human resource capacity of regulatory bodies, and the manner of private actors' influence on regulatory policy and implementation. CONCLUSION: Strengthening regulation to ensure the quality and availability of TB medicines in LMIC with emerging private markets may necessitate financial and technical inputs to upgrade regulatory bodies, as well as broader political and ethical actions to reorient and transform their current roles. PMID- 27694669 TI - Catastrophic Health Expenditure After the Implementation of Health Sector Evolution Plan: A Case Study in the West of Iran. AB - BACKGROUND: One of the main objectives of health systems is the financial protection against out-of-pocket (OOP) health expenditures. OOP health expenditures can lead to catastrophic payments, impoverishment or poverty among households. In Iran, health sector evolution plan (HSEP) has been implemented since 2014 in order to achieve universal health coverage and reduce the OOP health expenditures as a percentage of total health expenditures. This study aimed to explore the percentage of households facing catastrophic health expenditures (CHE) after the implementation of HSEP and the factors that determine CHE. METHODS: A total of 663 households were selected through a cluster sampling based on the census framework of Sanandaj Health Center in July 2015. Data were gathered using face-to-face interviews based on the household section of the World Health Survey questionnaire. In this study, according to the World Health Organization (WHO) definition, if household health expenditures were equal to or more than 40% of the household capacity to pay, household was considered to be facing CHE. The determinants of CHE were analyzed using logistic regression model. RESULTS: The rates of households facing CHE were 4.8%. The key determinants of CHE were household economic status, presence of elderly or disabled members in the household and utilization of inpatient or rehabilitation services. CONCLUSION: The comparison of our findings and those of other studies carried out using a methodology comparable with ours in different parts of Iran before the implementation of HSEP suggests that the implementation of recent reforms has reduced CHE at the household level. Utilization of inpatient and rehabilitation services, the presence of elderly or disabled members in the household and the low economic status of the household would increase the likelihood of facing CHE. These variables should be considered by health policy makers in order to review and revise content of recent reform, thus financially protecting public against CHE.

Throughout, the commentary signposts possible themes for Ha et al to consider for further analysis, and more generally, for future research using Kingdon's multiple streams theory. PMID- 27694670 TI - Adoption of Electronic Personal Health Records in Canada: Perceptions of Stakeholders. AB - BACKGROUND: Healthcare stakeholders have a great interest in the adoption and use of electronic personal health records (ePHRs) because of the potential benefits associated with them. Little is known, however, about the level of adoption of ePHRs in Canada and there is limited evidence concerning their benefits and implications for the healthcare system. This study aimed to describe the current situation of ePHRs in Canada and explore stakeholder perceptions regarding barriers and facilitators to their adoption. METHODS: Using a qualitative descriptive study design, we conducted semi-structured phone interviews between October 2013 and February 2014 with 35 individuals from seven Canadian provinces. The participants represented six stakeholder groups (patients, ePHR administrators, healthcare professionals, organizations interested in health technology development, government agencies, and researchers). A detailed summary of each interview was created and thematic analysis was conducted. RESULTS: We observed that there was no consensual definition of ePHR in Canada. Factors that could influence ePHR adoption were related to knowledge (confusion with other electronic medical records [EMRs] and lack of awareness), system design (usability and relevance), user capacities and attitudes (patient health literacy, education and interest, support for professionals), environmental factors (government commitment, targeted populations) and legal and ethical issues (information control and custody, confidentiality, privacy and security). CONCLUSION: ePHRs are slowly entering the Canadian healthcare landscape but provinces do not seem well-prepared for the implementation of this type of record. Guidance is needed on critical issues regarding ePHRs, such as ePHR definition, data ownership, access to information and interoperability with other electronic health records (EHRs). Better guidance on these issues would provide a greater awareness of ePHRs and inform stakeholders including clinicians, decision makers, patients and the public. In turn, it may facilitate their adoption in the country.

AB - Many public policy programs fail to translate ambitious headlines to on-the ground action. The reasons for this are many and varied, but for public administration and management scholars a large part of the gap between ambition and achievement is the challenge associated with the operation of the machinery of government itself, and how it relates to the other parties that it relies on to fulfill these outcomes. In their article, Carey and Friel set out key reasons why public health scholars should seek to better understand important ideas in public administration. In commenting on their contribution, I draw out two critical questions that are raised by this discussion: (i) what are boundaries and what forms do they take? and (ii) why work across boundaries? Expanding on these key questions extends the points made by Carey and Friel on the importance of understanding public administration and will better place public health scholars and practitioners to realise health outcomes.

AB - The World Health Organization's (WHO's) World Health Report 2010, "Health systems financing, the path to universal coverage," promoted universal health coverage (UHC) as an aspirational objective for country health systems. Yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the consideration of the budget constraint should be further strengthened in the ensuing debate on resource allocation toward UHC. Beyond the substantial financial constraints faced by low- and middle-income countries, additional considerations, such as the geographical context, the underlying country infrastructure, and the architecture of health systems, determine the feasibility, effectiveness, quality and cost of healthcare delivery. Therefore, increased production and use of local evidence tied to the criteria of health benefits, equity, financial risk protection, and costs accompanying health delivery are needed so that to highlight pathways and acceptable trade-offs toward UHC.

AB - It is well-established that for a considerable period the United Kingdom has spent proportionally less of its gross domestic product (GDP) on health-related services than almost any other comparable country. Average European spending on health (as a % of GDP) in the period 1980 to 2013 has been 19% higher than the United Kingdom, indicating that comparable countries give far greater fiscal priority to its health services, irrespective of its actual fiscal value or configuration. While the UK National Health Service (NHS) is a comparatively lean healthcare system, it is often regarded to be at a 'crisis' point on account of low levels of funding. Indeed, many state that currently the NHS has a sizeable funding gap, in part due to its recently reduced GDP devoted to health but mainly the challenges around increases in longevity, expectation and new medical costs. The right level of health funding is a political value judgement. As the data in this paper outline, if the UK 'afforded' the same proportional level of funding as the mean average European country, total expenditure would currently increase by one-fifth.

AB - BACKGROUND: Health is a basic human right necessary for the exercise of other human rights. Every human being is, therefore, entitled to the highest possible standard of health necessary to living a life of dignity. Establishment of patients' Charter is a step towards protecting the rights and responsibilities of patients, but violation of patients' rights is common in healthcare institutions, especially in the developing world. This study which was conducted between May 2013 and May 2014, assessed the operationalization of Ghana's Patients Charter in a peri-urban public hospital. METHODS: Qualitative data collection methods were used to collect data from 25 healthcare workers and patients who were purposively selected. The interview data were analyzed manually, using the principles of systematic text condensation. RESULTS: The findings indicate that the healthcare staff of the Polyclinic are aware of the existence of the patients' Charter and also know some of its contents. Patients have no knowledge of the existence or the contents of the Charter. Availability of the Charter, community sensitization, monitoring and orientation of staff are factors that promote the operationalization of the Charter, while institutional implementation procedures such as lack of complaint procedures and low knowledge among patients militate against operationalization of the Charter. CONCLUSION: Public health facilities should ensure that their patients are well-informed about their rights and responsibilities to facilitate effective implementation of the Charter. Also, patients' rights and responsibilities can be dramatized and broadcasted on television and radio in major Ghanaian languages to enhance awareness of Ghanaians on the Charter. PMID- 27694680 TI - Correcting India's Chronic Shortage of Drug Inspectors to Ensure the Production and Distribution of Safe, High-Quality Medicines. AB - BACKGROUND: Good drug regulation requires an effective system for monitoring and inspection of manufacturing and sales units. In India, despite widespread agreement on this principle, ongoing shortages of drug inspectors have been identified by national committees since 1975. The growth of India's pharmaceutical industry and its large export market makes the problem more acute. METHODS: The focus of this study is a case study of Maharashtra, which has 29% of India's manufacturing units and 38% of its medicines exports. India's regulations were reviewed, comparing international, national and state inspection norms with the actual number of inspectors and inspections. Twenty-six key informant interviews were conducted to ascertain the causes of the shortfall. RESULTS: In 2009-2010, 55% of the sanctioned posts of drug inspectors in Maharashtra were vacant. This resulted in a shortfall of 83%, based on the Mashelkar Committee's recommendations. Less than a quarter of the required inspections of manufacturing and sales units were undertaken. The Indian Drugs and Cosmetics Act and its Rules and Regulations make no provisions for drug inspectors and workforce planning norms, despite the growth and increasing complexity of India's pharmaceutical industry. CONCLUSION: The Maharashtra Food and Drug Administration (FDA) falls short of the Mashelkar Committee's recommended workforce planning norms. Legislation and political and operational support are required to produce needed changes. PMID- 27694681 TI - The Politico-Economic Challenges of Ghana's National Health Insurance Scheme Implementation. AB - BACKGROUND: National/social health insurance schemes have increasingly been seen in many low- and middle-income countries (LMICs) as a vehicle to universal health coverage (UHC) and a viable alternative funding mechanism for the health sector. Several countries, including Ghana, have thus introduced and implemented mandatory national health insurance schemes (NHIS) as part of reform efforts towards increasing access to health services. Ghana passed mandatory national health insurance (NHI) legislation (ACT 650) in 2003 and commenced nationwide implementation in 2004. Several peer review studies and other research reports have since assessed the performance of the scheme with positive rating while challenges also noted. This paper contributes to the literature on economic and political implementation challenges based on empirical evidence from the perspectives of the different category of actors and institutions involved in the process. METHODS: Qualitative in-depth interviews were held with 33 different category of participants in four selected district mutual health insurance schemes in Southern (two) and Northern (two) Ghana. This was to ascertain their views regarding the main challenges in the implementation process. The participants were selected through purposeful sampling, stakeholder mapping, and snowballing. Data was analysed using thematic grouping procedure. RESULTS: Participants identified political issues of over politicisation and political interference as main challenges. The main economic issues participants identified included low premiums or contributions; broad exemptions, poor gatekeeper enforcement system; and culture of curative and hospital-centric care. CONCLUSION: The study establishes that political and economic factors have influenced the implementation process and the degree to which the policy has been implemented as intended. Thus, we conclude that there is a synergy between implementation and politics; and achieving UHC under the NHIS requires political stewardship. Political leadership has the responsibility to build trust and confidence in the system by providing the necessary resources and backing with minimal interference in the operations. For sustainability of the scheme, authorities need to review the exemption policy, rate of contributions, especially, from informal sector employees and recruitment criteria of scheme workers, explore additional sources of funding and re-examine training needs of employees to strengthen their competences among others.

AB - Richard Saltman and Antonio Duran take up the challenging issue of governance in their article "Governance, Government and the Search for New Provider Models," and use two case studies of health policy changes in Sweden and Spain to shed light on the subject. In this commentary, I seek to link their conceptualization of governance, especially its interrelated roles at the macro, meso, and micro levels of health systems, with the case studies on which they report. While the case studies focus on the shifts in governance between the macro and meso levels and their impacts on achievement of desired policy outcomes, they also highlight the need to better integrate the dynamics of day to day operations within micro organizations into the overall governance picture.

It reinforces its message that an inclusive, participatory process is essential for ethical decision-making and underlines the crucial importance of good governance in setting fair priorities in healthcare. Solidarity on both national and international levels is needed to make progress towards the goal of universal health coverage (UHC). PMID- 27694684 TI - U-Form vs. M-Form: How to Understand Decision Autonomy Under Healthcare Decentralization? Comment on "Decentralisation of Health Services in Fiji: A Decision Space Analysis". AB - For more than three decades healthcare decentralization has been promoted in developing countries as a way of improving the financing and delivery of public healthcare. Decision autonomy under healthcare decentralization would determine the role and scope of responsibility of local authorities. Jalal Mohammed, Nicola North, and Toni Ashton analyze decision autonomy within decentralized services in Fiji. They conclude that the narrow decision space allowed to local entities might have limited the benefits of decentralization on users and providers. To discuss the costs and benefits of healthcare decentralization this paper uses the U-form and M-form typology to further illustrate the role of decision autonomy under healthcare decentralization. This paper argues that when evaluating healthcare decentralization, it is important to determine whether the benefits from decentralization are greater than its costs. The U-form and M-form framework is proposed as a useful typology to evaluate different types of institutional arrangements under healthcare decentralization. Under this model, the more decentralized organizational form (M-form) is superior if the benefits from flexibility exceed the costs of duplication and the more centralized organizational form (U-form) is superior if the savings from economies of scale outweigh the costly decision-making process from the center to the regions. Budgetary and financial autonomy and effective mechanisms to maintain local governments accountable for their spending behavior are key decision autonomy variables that could sway the cost-benefit analysis of healthcare decentralization.

AB - This brief commentary seeks to develop the analysis of Daniels, Porteny and Urrutia of the implications of expansion of the scope of health technology assessment (HTA) beyond issues of safety, efficacy, and cost-effectiveness. Drawing in particular on experience in the United Kingdom, it suggests that such expansion can be understood not only as a response to the problem of insufficiency of evidence, but also to that of legitimacy. However, as expansion of HTA also renders it more visibly political in character, it is plausible that its legitimacy may be undermined, rather than enhanced by, independence from the policy process.

AB - New strategies to prevent and early detect the cardiotoxic effects of the anticancer drug doxorubicin (DOXO) are required. MicroRNAs emerged as potential diagnostic, therapeutic and prognostic approaches in cardiovascular diseases. MiR 34a has a role in cardiac dysfunction and ageing and is involved in several cellular processes associated with DOXO cardiotoxicity. Our in vitro and in vivo results indicated that after DOXO exposure the levels of miR-34a are enhanced in cardiac cells, including Cardiac Progenitor Cells (CPCs). Since one of the determining event responsible for the initiation and evolution of the DOXO toxicity arises at the level of the CPC compartment, we evaluated if miR-34a pharmacological inhibition in these cells ameliorates the detrimental aftermath of the drug. AntimiR-34a has beneficial consequences on vitality, proliferation, apoptosis and senescence of DOXO-treated rat CPC. These effects are mediated by an increase of prosurvival miR-34a targets Bcl-2 and SIRT1, accompanied by a decrease of acetylated-p53 and p16INK4a. Importantly, miR-34a silencing also reduces the release of this miRNA from DOXO-exposed rCPCs, decreasing its negative paracrine effects on other rat cardiac cells. In conclusion, the silencing of miR-34a could represent a future therapeutic option for cardioprotection in DOXO toxicity and at the same time, it could be considered as a circulating biomarker for anthracycline-induced cardiac damage. PMID- 27694689 TI - eIF5B increases ASAP1 expression to promote HCC proliferation and invasion. AB - Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death worldwide. Despite the therapeutic advances that have been achieved during the past decade, the molecular pathogenesis underlying HCC remains poorly understood. In this study, we discovered that increased expression eukaryotic translation initiation factor 5B (eIF5B) was significantly correlated with aggressive characteristics and associated with shorter recurrence-free survival (RFS) and overall survival (OS) in a large cohort. We also found that eIF5B promoted HCC cell proliferation and migration in vitro and in vivo partly through increasing ASAP1 expression. Our findings strongly suggested that eIF5B could promote HCC progression and be considered a prognostic biomarker for HCC. PMID- 27694690 TI - Suppression of PC-1/PrLZ sensitizes prostate cancer cells to ionizing radiation by attenuating DNA damage repair and inducing autophagic cell death. AB - Radiotherapy is promising and effective for treating prostate cancer but the addition of a tumor cell radiosensitizer would improve therapeutic outcomes. PC 1/PrLZ, a TPD52 protein family member is frequently upregulated in advanced prostate cancer cells and may be a biomarker of aggressive prostate cancer. Therefore, we investigated the potential role of PC-1/PrLZ for increasing radioresistance in human prostate cancer cell lines. Growth curves and survival assays after g-ray irradiation confirmed that depletion of endogenous PC-1/PrLZ significantly increased prostate cancer cell radiosensitivity. Irradiation (IR) increased PC-1/PrLZ expression in a dose- and time-dependent manner and increased radiosensitivity in PC-1/PrLZ-suppressed cells was partially due to decreased DNA double strand break (DBS) repair which was measured with comet and gH2AX foci assays. Furthermore, depletion of PC-1/PrLZ impaired the IR-induced G2/M checkpoint, which has been reported to be correlate with radioresistance in cancer cells. PC-1/PrLZ-deficient cells exhibited higher level of autophagy when compared with control cells. Thus, specific inhibition of PC-1/PrLZ might provide a novel therapeutic strategy for radiosensitizing prostate cancer cells. PMID- 27694691 TI - Interleukin-6 expression contributes to lapatinib resistance through maintenance of stemness property in HER2-positive breast cancer cells. AB - Lapatinib is an inhibitor of human epidermal growth factor receptor 2 (HER2), which is overexpressed in 20-25% of breast cancers. Clinically, lapatinib has shown promising benefits for HER2-positive breast cancer patients; however, patients eventually acquire resistance, limiting its long-term use. In a previous study, we found that interleukin-6 (IL-6) production was increased in acquired lapatinib-resistant HER2-positive breast cancer cells. In the present study, we confirmed that lapatinib-resistant cells had elevated IL-6 expression and also maintained both stemness population and property. The increase in IL-6 was required for stemness property maintenance, which was mediated primarily through the activation of signal transducer and activator of transcription 3 (STAT3). Blocking IL-6 activity reduced spheroid formation, cell viability and subsequently overcame lapatinib resistance, whereas stimulation of IL-6 rendered parental cells more resistant to lapatinib-induced cytotoxicity. These results point to a novel mechanism underlying lapatinib resistance and provide a potential strategy to overcome resistance via IL-6 inhibition. PMID- 27694694 TI - Pharmacokinetics of intravenous peramivir in the airway epithelial lining fluid of healthy volunteers. AB - BACKGROUND: Some subtypes of influenza virus, such as H5N1 and H7N9, cause severe viral pneumonia, for which the intraluminal concentration of the anti-influenza agent in the airway is critical. However, the pharmacokinetics of peramivir, the only available injectable neuraminidase inhibitor formulation, in the airway epithelial lining fluid (ELF) remains unclear. In this study, we aimed to determine the time course of peramivir in the pharyngeal ELF, bronchial ELF and plasma of healthy volunteers using bronchoscopic microsampling technique. METHODS: Six healthy volunteers were studied. After baseline plasma sampling, 0.3 g peramivir was intravenously injected over 0.5 h. ELF was obtained from the upper and lower airways using bronchoscopic microsampling at the end of the infusion (0.5 h) and after 1.0, 1.5, 2.0, 2.5, 3.0, 4.0 and 5.0 h. The concentrations of peramivir in the ELFs and in the plasma were quantified by LC/MS/MS analysis. RESULTS: The mean maximum concentration (Cmax) in pharyngeal ELF, bronchial ELF and plasma was 1.20 +/-0.42, 9.60 +/-2.30 and 50.52 +/-17.51 ng/ml, respectively. The penetration ratio at Cmax in pharyngeal and bronchial ELFs was 2.4 and 19.0, respectively. The ratio of the area under the curve from 0 to infinity in pharyngeal and bronchial ELFs was 4.8 and 39.1 mg*min/l, respectively. CONCLUSIONS: The time course of peramivir concentration in the ELFs revealed that concentrations above the 50% inhibitory concentration value of influenza were achieved in the upper and lower airways. Therefore, peramivir could be an important treatment option for influenza viral pneumonia. PMID- 27694692 TI - Inhibition of insulin-like growth factor II (IGF-II)-dependent cell growth by multidentate pentamannosyl 6-phosphate-based ligands targeting the mannose 6 phosphate/IGF-II receptor. AB - The mannose 6-phosphate/insulin-like growth factor II receptor (M6P/IGF2R) binds M6P-capped ligands and IGF-II at different binding sites within the ectodomain and mediates ligand internalization and trafficking to the lysosome. Multivalent M6P-based ligands can cross-bridge the M6P/IGF2R, which increases the rate of receptor internalization, permitting IGF-II binding as a passenger ligand and subsequent trafficking to the lysosome, where the IGF-II is degraded. This unique feature of the receptor may be exploited to design novel therapeutic agents against IGF-II-dependent cancers that will lead to decreased bioavailable IGF-II within the tumor microenvironment. We have designed a panel of M6P-based ligands that bind to the M6P/IGF2R with high affinity in a bivalent manner and cause decreased cell viability. We present evidence that our ligands bind through the M6P-binding sites of the receptor and facilitate internalization and degradation of IGF-II from conditioned medium to mediate this cellular response. To our knowledge, this is the first panel of synthetic bivalent ligands for the M6P/IGF2R that can take advantage of the ligand-receptor interactions of the M6P/IGF2R to provide proof-of-principle evidence for the feasibility of novel chemotherapeutic agents that decrease IGF-II-dependent growth of cancer cells.

AB - Resistively switching oxides are promising materials for use in electronic applications such as nonvolatile memories, logic gates, and artificial synapses. This work presents the bipolar resistive switching (BRS) in YMnO3/Nb:SrTiO3 pn heterojunctions. A thermally driven electroforming process is required prior to the observed BRS. Results indicate that the BRS in YMnO3/Nb:SrTiO3 originates from the combined effects of charge trapping and detrapping processes along with the electro-migration of charged point defects in the depletion layer of the pn heterojunction. It is shown that the built-in voltage of the pn-heterojunctions can be tuned by the oxygen partial pressure during growth of the YMnO3 thin film and impacts the working parameters of the resistively switching cell. This study provides a guideline for material engineering of bipolar resistive switches based on pn-heterojunctions. PMID- 27694696 TI - The impact of x-ray tube stabilization on localized radiation dose in axial CT scans: initial results in CTDI phantoms. AB - Rise, fall, and stabilization of the x-ray tube output occur immediately before and after data acquisition on some computed tomography (CT) scanners and are believed to contribute additional dose to anatomy facing the x-ray tube when it powers on or off. In this study, we characterized the dose penalty caused by additional radiation exposure during the rise, stabilization, and/or fall time (referred to as overscanning). A 32 cm CT dose-index (CTDI) phantom was scanned on three CT scanners: GE Healthcare LightSpeed VCT, GE Healthcare Discovery CT750 HD, and Siemens Somatom Definition Flash. Radiation exposure was detected for various x-ray tube start acquisition angles using a 10 cm pencil ionization chamber placed in the peripheral chamber hole at the phantom's 12 o'clock position. Scan rotation time, ionization chamber location, phantom diameter, and phantom centering were varied to quantify their effects on the dose penalty caused by overscanning. For 1 s single, axial rotations, CTDI at the 12 o'clock chamber position (CTDI100, 12:00) was 6.1%, 4.0%, and 4.4% higher when the start angle of the x-ray tube was aligned at the top of the gantry (12 o'clock) versus when the start angle was aligned at 9 o'clock for the Siemens Flash, GE CT750 HD, and GE VCT scanner, respectively. For the scanners' fastest rotation times (0.285 s for the Siemens and 0.4 s for both GE scanners), the dose penalties increased to 22.3%, 10.7%, and 10.5%, respectively, suggesting a trade-off between rotation speed and the dose penalty from overscanning. In general, overscanning was shown to have a greater radiation dose impact for larger diameter phantoms, shorter rotation times, and to peripheral phantom locations. Future research is necessary to determine an appropriate method for incorporating the localized dose penalty from overscanning into standard dose metrics, as well as to assess the impact on organ dose. PMID- 27694697 TI - Unipolar resistive switching and tunneling oscillations in isolated Si-SiO x core shell nanostructure. AB - Unipolar resistive switching (URS) is observed in isolated Si-SiO x core-shell nanostructures. I-V characteristics recorded by a conductive atomic force microscope tip show SET and RESET processes with self compliance behavior. Hopping of carriers through defect states in the high resistance state (HRS) and space charge limited conduction in the low resistance state (LRS) are found to be the dominant carrier transport mechanisms in Si-SiO x core-shell nanostructures. URS between LRS and HRS may be attributed to the transition between hydrogen bridge (Si-H-Si) and hydrogen doublet (Si-HH-Si) defects. During RESET process, charge carriers tunnel through the nanostructure giving rise to oscillatory conduction. PMID- 27694698 TI - Selective in situ potential-assisted SAM formation on multi electrode arrays. AB - The selective modification of individual components in a biosensor array is challenging. To address this challenge, we present a generalizable approach to selectively modify and characterize individual gold surfaces in an array, in an in situ manner. This is achieved by taking advantage of the potential dependent adsorption/desorption of surface-modified organic molecules. Control of the applied potential of the individual sensors in an array where each acts as a working electrode provides differential derivatization of the sensor surfaces. To demonstrate this concept, two different self-assembled monolayer (SAM)-forming electrochemically addressable omega-ferrocenyl alkanethiols (C11) are chemisorbed onto independent but spatially adjacent gold electrodes. The ferrocene alkanethiol does not chemisorb onto the surface when the applied potential is cathodic relative to the adsorption potential and the electrode remains underivatized. However, applying potentials that are modestly positive relative to the adsorption potential leads to extensive coverage within 10 min. The resulting SAM remains in a stable state while held at potentials <200 mV above the adsorption potential. In this state, the chemisorbed SAM does not significantly desorb nor do new ferrocenylalkythiols adsorb. Using three set applied potentials provides for controlled submonolayer alkylthiol marker coverage of each independent gold electrode. These three applied potentials are dependent upon the specifics of the respective adsorbate. Characterization of the ferrocene-modified electrodes via cyclic voltammetry demonstrates that each specific ferrocene marker is exclusively adsorbed to the desired target electrode. PMID- 27694699 TI - Study of mechanical behavior of AFM silicon tips under mechanical load. AB - In this paper we address critical issues concerning calibration of AFM based methods used for nanoscale mechanical characterization of materials. It has been shown that calibration approaches based on macroscopic models for contact mechanics may yield excellent results in terms of the indentation modulus of the sample, but fail to provide a comprehensive and actual information concerning the tip-sample contact radius or the mechanical properties of the tip. Explanations for the severely reduced indentation modulus of the tip included the inadequacies of the models used for calculations of the tip-sample contact stiffness, discrepancies in the actual and ideal shape of the tip, presence of the amorphous silicon phase within the silicon tip, as well as negligence of the actual size of the stress field created in the tip during elastic interactions. To clarify these issues, we investigated the influence of the mechanical load applied to four AFM silicon tips on their crystalline state by exposing them to systematically increasing loads, evaluating the character of the tip-sample interactions via the load-unload stiffness curves, and assessing the state of the tips from HR-TEM images. The results presented in this paper were obtained in a series of relatively simple and basic atomic force acoustic microscopy (AFAM) experiments. The novel combination of TEM imaging of the AFM tips with the analysis of the load-unload stiffness curves gave us a detailed insight into their mechanical behavior under load conditions. We were able to identify the limits for the elastic interactions, as well as the hallmarks for phase transformation and dislocation formation and movement. The comparison of the physical dimensions of the AFM tips, geometry parameters determined from the values of the contact stiffness, and the information on the crystalline state of the tips allowed us a better understanding of the nanoscale contact. PMID- 27694700 TI - Optimization-based image reconstruction with artifact reduction in C-arm CBCT. AB - We investigate an optimization-based reconstruction, with an emphasis on image artifact reduction, from data collected in C-arm cone-beam computed tomography (CBCT) employed in image-guided interventional procedures. In the study, an image to be reconstructed is formulated as a solution to a convex optimization program in which a weighted data divergence is minimized subject to a constraint on the image total variation (TV); a data-derivative fidelity is introduced in the program specifically for effectively suppressing dominant, low-frequency data artifact caused by, e.g. data truncation; and the Chambolle-Pock (CP) algorithm is tailored to reconstruct an image through solving the program. Like any other reconstructions, the optimization-based reconstruction considered depends upon numerous parameters. We elucidate the parameters, illustrate their determination, and demonstrate their impact on the reconstruction. The optimization-based reconstruction, when applied to data collected from swine and patient subjects, yields images with visibly reduced artifacts in contrast to the reference reconstruction, and it also appears to exhibit a high degree of robustness against distinctively different anatomies of imaged subjects and scanning conditions of clinical significance. Knowledge and insights gained in the study may be exploited for aiding in the design of practical reconstructions of truly clinical-application utility. PMID- 27694701 TI - Multiresolution iterative reconstruction in high-resolution extremity cone-beam CT. AB - Application of model-based iterative reconstruction (MBIR) to high resolution cone-beam CT (CBCT) is computationally challenging because of the very fine discretization (voxel size <100 um) of the reconstructed volume. Moreover, standard MBIR techniques require that the complete transaxial support for the acquired projections is reconstructed, thus precluding acceleration by restricting the reconstruction to a region-of-interest. To reduce the computational burden of high resolution MBIR, we propose a multiresolution penalized-weighted least squares (PWLS) algorithm, where the volume is parameterized as a union of fine and coarse voxel grids as well as selective binning of detector pixels. We introduce a penalty function designed to regularize across the boundaries between the two grids. The algorithm was evaluated in simulation studies emulating an extremity CBCT system and in a physical study on a test-bench. Artifacts arising from the mismatched discretization of the fine and coarse sub-volumes were investigated. The fine grid region was parameterized using 0.15 mm voxels and the voxel size in the coarse grid region was varied by changing a downsampling factor. No significant artifacts were found in either of the regions for downsampling factors of up to 4*. For a typical extremities CBCT volume size, this downsampling corresponds to an acceleration of the reconstruction that is more than five times faster than a brute force solution that applies fine voxel parameterization to the entire volume. For certain configurations of the coarse and fine grid regions, in particular when the boundary between the regions does not cross high attenuation gradients, downsampling factors as high as 10* can be used without introducing artifacts, yielding a ~50* speedup in PWLS. The proposed multiresolution algorithm significantly reduces the computational burden of high resolution iterative CBCT reconstruction and can be extended to other applications of MBIR where computationally expensive, high-fidelity forward models are applied only to a sub-region of the field-of-view. PMID- 27694702 TI - LET-dependent radiosensitization effects of gold nanoparticles for proton irradiation. AB - The development of new modalities and protocols is of major interest to improve the outcome of cancer treatment. Given the appealing physical properties of protons and the emerging evidence of biological relevance of the use of gold nanoparticles (GNPs), the radiosensitization effects of GNPs (5 or 10 nm) have been investigated in vitro in combination with a proton beam of different linear energy transfer (LET). After the incubation with GNPs for 24 h, nanoparticles were observed in the cytoplasm of A431 cells exposed to 10 nm GNPs, and in the cytoplasm as well as the nucleus of cells exposed to 5 nm GNPs. Cell uptake of 0.05 mg ml-1 of GNPs led to 0.78 pg Au/cell and 0.30 pg Au/cell after 24 h incubation for 10 and 5 nm GNPs respectively. A marked radiosensitization effect of GNPs was observed with 25 keV MUm-1 protons, but not with 10 keV MUm-1 protons. This effect was more pronounced for 10 nm GNPs than for 5 nm GNPs. By using a radical scavenger, a major role of reactive oxygen species in the amplification of the death of irradiated cell was identified. All together, these results open up novel perspectives for using high-Z metallic NPs in protontherapy. PMID- 27694703 TI - The effect of temperature dependent tissue parameters on acoustic radiation force induced displacements. AB - Multiple ultrasound elastography techniques rely on acoustic radiation force (ARF) in monitoring high-intensity focused ultrasound (HIFU) therapy. However, ARF is dependent on tissue attenuation and sound speed, both of which are also known to change with temperature making the therapy monitoring more challenging. Furthermore, the viscoelastic properties of tissue are also temperature dependent, which affects the displacements induced by ARF. The aim of this study is to quantify the temperature dependent changes in the acoustic and viscoelastic properties of liver and investigate their effect on ARF induced displacements by using both experimental methods and simulations. Furthermore, the temperature dependent viscoelastic properties of liver are experimentally measured over a frequency range of 0.1-200 Hz at temperatures reaching 80 degrees C, and both conventional and fractional Zener models are used to fit the data. The fractional Zener model was found to fit better with the experimental viscoelasticity data with respect to the conventional model with up to two orders of magnitude lower sum of squared errors (SSE). The characteristics of experimental displacement data were also seen in the simulations due to the changes in attenuation coefficient and lesion development. At low temperatures before thermal ablation, attenuation was found to affect the displacement amplitude. At higher temperature, the decrease in displacement amplitude occurs approximately at 60-70 degrees C due to the combined effect of viscoelasticity changes and lesion growth overpowering the effect of attenuation. The results suggest that it is necessary to monitor displacement continuously during HIFU therapy in order to ascertain when ablation occurs. PMID- 27694704 TI - Image reconstruction algorithm for optically stimulated luminescence 2D dosimetry using laser-scanned Al2O3:C and Al2O3:C,Mg films. AB - The objective of this work was to develop an image reconstruction algorithm for 2D dosimetry using Al2O3:C and Al2O3:C,Mg optically stimulated luminescence (OSL) films imaged using a laser scanning system. The algorithm takes into account parameters associated with detector properties and the readout system. Pieces of Al2O3:C films (~8 mm * 8 mm * 125 um) were irradiated and used to simulate dose distributions with extreme dose gradients (zero and non-zero dose regions). The OSLD film pieces were scanned using a custom-built laser-scanning OSL reader and the data obtained were used to develop and demonstrate a dose reconstruction algorithm. The algorithm includes corrections for: (a) galvo hysteresis, (b) photomultiplier tube (PMT) linearity, (c) phosphorescence, (d) 'pixel bleeding' caused by the 35 ms luminescence lifetime of F-centers in Al2O3, (e) geometrical distortion inherent to Galvo scanning system, and (f) position dependence of the light collection efficiency. The algorithm was also applied to 6.0 cm * 6.0 cm * 125 MUm or 10.0 cm * 10.0 cm * 125 um Al2O3:C and Al2O3:C,Mg films exposed to megavoltage x-rays (6 MV) and 12C beams (430 MeV u-1). The results obtained using pieces of irradiated films show the ability of the image reconstruction algorithm to correct for pixel bleeding even in the presence of extremely sharp dose gradients. Corrections for geometric distortion and position dependence of light collection efficiency were shown to minimize characteristic limitations of this system design. We also exemplify the application of the algorithm to more clinically relevant 6 MV x-ray beam and a 12C pencil beam, demonstrating the potential for small field dosimetry. The image reconstruction algorithm described here provides the foundation for laser-scanned OSL applied to 2D dosimetry. PMID- 27694705 TI - EVolution: an edge-based variational method for non-rigid multi-modal image registration. AB - Image registration is part of a large variety of medical applications including diagnosis, monitoring disease progression and/or treatment effectiveness and, more recently, therapy guidance. Such applications usually involve several imaging modalities such as ultrasound, computed tomography, positron emission tomography, x-ray or magnetic resonance imaging, either separately or combined. In the current work, we propose a non-rigid multi-modal registration method (namely EVolution: an edge-based variational method for non-rigid multi-modal image registration) that aims at maximizing edge alignment between the images being registered. The proposed algorithm requires only contrasts between physiological tissues, preferably present in both image modalities, and assumes deformable/elastic tissues. Given both is shown to be well suitable for non-rigid co-registration across different image types/contrasts (T1/T2) as well as different modalities (CT/MRI). This is achieved using a variational scheme that provides a fast algorithm with a low number of control parameters. Results obtained on an annotated CT data set were comparable to the ones provided by state-of-the-art multi-modal image registration algorithms, for all tested experimental conditions (image pre-filtering, image intensity variation, noise perturbation). Moreover, we demonstrate that, compared to existing approaches, our method possesses increased robustness to transient structures (i.e. that are only present in some of the images). PMID- 27694706 TI - Automatic landmark generation for deformable image registration evaluation for 4D CT images of lung. AB - Deformable image registration (DIR) has become a common tool in medical imaging across both diagnostic and treatment specialties, but the methods used offer varying levels of accuracy. Evaluation of DIR is commonly performed using manually selected landmarks, which is subjective, tedious and time consuming. We propose a semi-automated method that saves time and provides accuracy comparable to manual selection. Three landmarking methods including manual (with two independent observers), scale invariant feature transform (SIFT), and SIFT with manual editing (SIFT-M) were tested on 10 thoracic 4DCT image studies corresponding to the 0% and 50% phases of respiration. Results of each method were evaluated against a gold standard (GS) landmark set comparing both mean and proximal landmark displacements. The proximal method compares the local deformation magnitude between a test landmark pair and the closest GS pair. Statistical analysis was done using an intra class correlation (ICC) between test and GS displacement values. The creation time per landmark pair was 22, 34, 2.3, and 4.3 s for observers 1 and 2, SIFT, and SIFT-M methods respectively. Across 20 lungs from the 10 CT studies, the ICC values between the GS and observer 1 and 2, SIFT, and SIFT-M methods were 0.85, 0.85, 0.84, and 0.82 for mean lung deformation, and 0.97, 0.98, 0.91, and 0.96 for proximal landmark deformation, respectively. SIFT and SIFT-M methods have an accuracy that is comparable to manual methods when tested against a GS landmark set while saving 90% of the time. The number and distribution of landmarks significantly affected the analysis as manifested by the different results for mean deformation and proximal landmark deformation methods. Automatic landmark methods offer a promising alternative to manual landmarking, if the quantity, quality and distribution of landmarks can be optimized for the intended application.

AB - Sharp dose fall-off is the hallmark of brain radiosurgery for the purpose of delivering high dose radiation to the target while minimizing peripheral dose to regional normal brain tissue. In this study, a technique was developed to enhance the peripheral dose gradient by magnifying the total number of beams focused toward each isocenter through pre-programmed patient head tilting. This technique was tested in clinical settings on a dedicated brain radiosurgical system (GKPFX, Gamma Knife Perfexion, Elekta Oncology) by comparing dosimetry as well as delivery efficiency for 20 radiosurgical cases previously treated with the system. The 3-fold beam number enhancement (BNE) treatment plans were found to produce nearly identical target volume coverage (absolute value < 0.5%, P > 0.2) and dose conformity (BNE CI = 1.41 +/- 0.22 versus 1.41 +/- 0.11, P > 0.99) as the original treatment plans. The total beam-on time for the 3-fold BNE treatment plans were also found to be comparable (<0.5 min or 2%) with those of the original treatment plans for all the cases. However, BNE treatment plans significantly improved the mean gradient index (BNE GI = 2.94 +/- 0.27 versus original GI = 2.98 +/- 0.28 P < 0.0001) and low-level isodose volumes, e.g. 20-50% prescribed isodose volumes, by 1.7%-3.9% (P < 0.03). With further 4-5 fold increase in the total number of beams, the absolute gradient index can decrease by as much as -0.5 in absolute value or -20% for a treatment. In conclusion, BNE via patient head tilt has been demonstrated to be a clinically suitable and efficient technique for physically sharpening the peripheral dose gradient for brain radiosurgery. PMID- 27694707 TI - Molecular image-directed biopsies: improving clinical biopsy selection in patients with multiple tumors. AB - Site selection for image-guided biopsies in patients with multiple lesions is typically based on clinical feasibility and physician preference. This study outlines the development of a selection algorithm that, in addition to clinical requirements, incorporates quantitative imaging data for automatic identification of candidate lesions for biopsy. The algorithm is designed to rank potential targets by maximizing a lesion-specific score, incorporating various criteria separated into two categories: (1) physician-feasibility category including physician-preferred lesion location and absolute volume scores, and (2) imaging based category including various modality and application-specific metrics. This platform was benchmarked in two clinical scenarios, a pre-treatment setting and response-based setting using imaging from metastatic prostate cancer patients with high disease burden (multiple lesions) undergoing conventional treatment and receiving whole-body [18F]NaF PET/CT scans pre- and mid-treatment. Targeting of metastatic lesions was robust to different weighting ratios and candidacy for biopsy was physician confirmed. Lesion ranked as top targets for biopsy remained so for all patients in pre-treatment and post-treatment biopsy selection after sensitivity testing was completed for physician-biased or imaging-biased scenarios. After identifying candidates, biopsy feasibility was evaluated by a physician and confirmed for 90% (32/36) of high-ranking lesions, of which all top choices were confirmed. The remaining cases represented lesions with high anatomical difficulty for targeting, such as proximity to sciatic nerve. This newly developed selection method was successfully used to quantitatively identify candidate lesions for biopsies in patients with multiple lesions. In a prospective study, we were able to successfully plan, develop, and implement this technique for the selection of a pre-treatment biopsy location. PMID- 27694710 TI - Structural instability and phase co-existence driven non-Gaussian resistance fluctuations in metal nanowires at low temperatures. AB - We report a detailed experimental study of the resistance fluctuations measured at low temperatures in high quality metal nanowires ranging in diameter from 15 200 nm. The wires exhibit co-existing face-centered-cubic and 4H hcp phases of varying degrees as determined from the x-ray diffraction data. We observe the appearance of a large non-Gaussian noise for nanowires of diameter smaller than 50 nm over a certain temperature range around ~30 K. The diameter range ~30 nm, where the noise has maxima coincides with the maximum volume fraction of the co existing 4H hcp phase thus establishing a strong link between the fluctuation and the phase co-existence. The resistance fluctuation in the same temperature range also shows a deviation of [Formula: see text] behavior at low frequency with appearance of single frequency Lorentzian type contribution in the spectral power density. The fluctuations are thermally activated with an activation energy [Formula: see text] meV, which is of same order as the activation energy of creation of stacking fault in FCC metals that leads to the co-existing crystallographic phases. Combining the results of crystallographic studies of the nanowires and analysis of the resistance fluctuations we could establish the correlation between the appearance of the large resistance noise and the onset of phase co-existence in these nanowires. PMID- 27694709 TI - A novel anthropomorphic flow phantom for the quantitative evaluation of prostate DCE-MRI acquisition techniques. AB - A novel anthropomorphic flow phantom device has been developed, which can be used for quantitatively assessing the ability of magnetic resonance imaging (MRI) scanners to accurately measure signal/concentration time-intensity curves (CTCs) associated with dynamic contrast-enhanced (DCE) MRI. Modelling of the complex pharmacokinetics of contrast agents as they perfuse through the tumour capillary network has shown great promise for cancer diagnosis and therapy monitoring. However, clinical adoption has been hindered by methodological problems, resulting in a lack of consensus regarding the most appropriate acquisition and modelling methodology to use and a consequent wide discrepancy in published data. A heretofore overlooked source of such discrepancy may arise from measurement errors of tumour CTCs deriving from the imaging pulse sequence itself, while the effects on the fidelity of CTC measurement of using rapidly-accelerated sequences such as parallel imaging and compressed sensing remain unknown. The present work aimed to investigate these features by developing a test device in which 'ground truth' CTCs were generated and presented to the MRI scanner for measurement, thereby allowing for an assessment of the DCE-MRI protocol to accurately measure this curve shape. The device comprised a four-pump flow system wherein CTCs derived from prior patient prostate data were produced in measurement chambers placed within the imaged volume. The ground truth was determined as the mean of repeat measurements using an MRI-independent, custom-built optical imaging system. In DCE-MRI experiments, significant discrepancies between the ground truth and measured CTCs were found for both tumorous and healthy tissue-mimicking curve shapes. Pharmacokinetic modelling revealed errors in measured K trans, v e and k ep values of up to 42%, 31%, and 50% respectively, following a simple variation of the parallel imaging factor and number of signal averages in the acquisition protocol. The device allows for the quantitative assessment and standardisation of DCE-MRI protocols (both existing and emerging). PMID- 27694711 TI - Why is it difficult to wash aphids off from superhydrophobic kale? AB - Many varieties of the cabbage family have leaves covered with superhydrophobic epicuticular wax, which provides them with self-cleaning characteristics. Since the wax also lowers insect adhesion, rinsing of the leaves with water should be an effective way of removing the insects. Conversely, we report that superhydrophobicity of tuscan kale increases resistance of aphids to hydrodynamic removal. The exterior surface of the insects is also superhydrophobic and acts as an extension of the leaf's surface. As a result even at moderate impact velocities impinging water drops cannot penetrate under the pests. Consequently, liquid impact aids the insect's adhesion by increasing the normal compressive forces they experience. We show that on a hydrophilic arugula leaf this mechanism is absent, and aphids can be easily washed off with water, as it is able to penetrate underneath them. As for removal of aphids from Tuscan kale, we show that lower surface tension liquids, such as oils and soapy water are more effective, because they are able to wet both the plant and insect surfaces. We also show that aerodynamic removal of aphids consisting of simply exposing the invaded leaf to an air flow is most effective. PMID- 27694713 TI - A simplified analytical random walk model for proton dose calculation. AB - We propose an analytical random walk model for proton dose calculation in a laterally homogeneous medium. A formula for the spatial fluence distribution of primary protons is derived. The variance of the spatial distribution is in the form of a distance-squared law of the angular distribution. To improve the accuracy of dose calculation in the Bragg peak region, the energy spectrum of the protons is used. The accuracy is validated against Monte Carlo simulation in water phantoms with either air gaps or a slab of bone inserted. The algorithm accurately reflects the dose dependence on the depth of the bone and can deal with small-field dosimetry. We further applied the algorithm to patients' cases in the highly heterogeneous head and pelvis sites and used a gamma test to show the reasonable accuracy of the algorithm in these sites. Our algorithm is fast for clinical use. PMID- 27694712 TI - Recent developments and comprehensive evaluations of a GPU-based Monte Carlo package for proton therapy. AB - Monte Carlo (MC) simulation is commonly considered as the most accurate dose calculation method for proton therapy. Aiming at achieving fast MC dose calculations for clinical applications, we have previously developed a graphics processing unit (GPU)-based MC tool, gPMC. In this paper, we report our recent updates on gPMC in terms of its accuracy, portability, and functionality, as well as comprehensive tests on this tool. The new version, gPMC v2.0, was developed under the OpenCL environment to enable portability across different computational platforms. Physics models of nuclear interactions were refined to improve calculation accuracy. Scoring functions of gPMC were expanded to enable tallying particle fluence, dose deposited by different particle types, and dose-averaged linear energy transfer (LETd). A multiple counter approach was employed to improve efficiency by reducing the frequency of memory writing conflict at scoring. For dose calculation, accuracy improvements over gPMC v1.0 were observed in both water phantom cases and a patient case. For a prostate cancer case planned using high-energy proton beams, dose discrepancies in beam entrance and target region seen in gPMC v1.0 with respect to the gold standard tool for proton Monte Carlo simulations (TOPAS) results were substantially reduced and gamma test passing rate (1%/1 mm) was improved from 82.7%-93.1%. The average relative difference in LETd between gPMC and TOPAS was 1.7%. The average relative differences in the dose deposited by primary, secondary, and other heavier particles were within 2.3%, 0.4%, and 0.2%. Depending on source proton energy and phantom complexity, it took 8-17 s on an AMD Radeon R9 290x GPU to simulate [Formula: see text] source protons, achieving less than [Formula: see text] average statistical uncertainty. As the beam size was reduced from 10 * 10 cm2 to 1 * 1 cm2, the time on scoring was only increased by 4.8% with eight counters, in contrast to a 40% increase using only one counter. With the OpenCL environment, the portability of gPMC v2.0 was enhanced. It was successfully executed on different CPUs and GPUs and its performance on different devices varied depending on processing power and hardware structure. PMID- 27694714 TI - Review of plastic and liquid scintillation dosimetry for photon, electron, and proton therapy. AB - While scintillation dosimetry has been around for decades, the need for a dosimeter tailored to the reality of modern radiation therapy-in particular a real-time, water-equivalent, energy-independent dosimeter with high spatial resolution-has generated renewed interest in scintillators over the last 10 years. With the advent of at least one commercial plastic scintillation dosimeter and the ever-growing scientific literature on this subject, this topical review is intended to provide the medical physics community with a wide overview of scintillation physics, related optical concepts, and applications of plastic scintillation dosimetry. PMID- 27694715 TI - A correction scheme for a simplified analytical random walk model algorithm of proton dose calculation in distal Bragg peak regions. AB - The lateral homogeneity assumption is used in most analytical algorithms for proton dose, such as the pencil-beam algorithms and our simplified analytical random walk model. To improve the dose calculation in the distal fall-off region in heterogeneous media, we analyzed primary proton fluence near heterogeneous media and propose to calculate the lateral fluence with voxel-specific Gaussian distributions. The lateral fluence from a beamlet is no longer expressed by a single Gaussian for all the lateral voxels, but by a specific Gaussian for each lateral voxel. The voxel-specific Gaussian for the beamlet of interest is calculated by re-initializing the fluence deviation on an effective surface where the proton energies of the beamlet of interest and the beamlet passing the voxel are the same. The dose improvement from the correction scheme was demonstrated by the dose distributions in two sets of heterogeneous phantoms consisting of cortical bone, lung, and water and by evaluating distributions in example patients with a head-and-neck tumor and metal spinal implants. The dose distributions from Monte Carlo simulations were used as the reference. The correction scheme effectively improved the dose calculation accuracy in the distal fall-off region and increased the gamma test pass rate. The extra computation for the correction was about 20% of that for the original algorithm but is dependent upon patient geometry. PMID- 27694716 TI - Scatter free imaging for the improvement of breast cancer detection in mammography. AB - In mammography, the reduction of scattered x-rays is vital due to the low contrast or small dimension of the details that are searched for. The typical method of doing so in current conventional mammography is the anti-scatter grid. The disadvantage of this method is the absorption of a proportion of the primary beam and therefore an increase in dose is required to compensate for the loss of counts. An alternative method is proposed, using quasi-monochromatic beams and a pixellated spectroscopic detector. As Compton-scattered x-rays lose energy in the scattering process, they are detected at a lower energy in the spectrum. Therefore the spectrum can be windowed around the monochromatic energy peak, removing the scattered x-rays from the image. The work presented here shows contrast improvement of up to 50% and contrast to noise ratio improvements of around 20% for scatter free imaging in comparison to full spectrum imaging. Contrast improvements of around 45% were found when comparing scatter free images to conventional polychromatic imaging for both the low contrast test object and the Rachel anthropomorphic breast phantom. PMID- 27694718 TI - Dielectric characterization of healthy and malignant colon tissues in the 0.5-18 GHz frequency band. AB - Several reports over the last few decades have shown that the dielectric properties of healthy and malignant tissues of the same body organ usually show different values. However, no intensive dielectric studies of human colon tissue have been performed, despite colon cancer's being one of the most common types of cancer in the world. In order to provide information regarding this matter, a dielectric characterization of healthy and malignant colon tissues is presented. Measurements are performed on ex vivo surgery samples obtained from 20 patients, using an open-ended coaxial probe in the 0.5-18 GHz frequency band. Results show that the dielectric constant of colon cancerous tissue is 8.8% higher than that of healthy tissues (p = 0.002). Besides, conductivity is about 10.6% higher, but in this case measurements do not have statistical significance (p = 0.038). Performing an analysis per patient, the differences in dielectric constant between healthy and malignant tissues appear systematically. Particularized results for specific frequencies (500 MHz, 900 MHz, 2.45 GHz, 5 GHz, 8.5 GHz and 15 GHz) are also reported. The findings have potential application in early-stage cancer detection and diagnosis, and can be useful in developing new tools for hyperthermia treatments as well as creating electromagnetic models of healthy and cancerous tissues. PMID- 27694717 TI - An accelerated photo-magnetic imaging reconstruction algorithm based on an analytical forward solution and a fast Jacobian assembly method. AB - We previously introduced photo-magnetic imaging (PMI), an imaging technique that illuminates the medium under investigation with near-infrared light and measures the induced temperature increase using magnetic resonance thermometry (MRT). Using a multiphysics solver combining photon migration and heat diffusion, PMI models the spatiotemporal distribution of temperature variation and recovers high resolution optical absorption images using these temperature maps. In this paper, we present a new fast non-iterative reconstruction algorithm for PMI. This new algorithm uses analytic methods during the resolution of the forward problem and the assembly of the sensitivity matrix. We validate our new analytic-based algorithm with the first generation finite element method (FEM) based reconstruction algorithm previously developed by our team. The validation is performed using, first synthetic data and afterwards, real MRT measured temperature maps. Our new method accelerates the reconstruction process 30-fold when compared to a single iteration of the FEM-based algorithm. PMID- 27694719 TI - Effective particle energies for stopping power calculation in radiotherapy treatment planning with protons and helium, carbon, and oxygen ions. AB - The stopping power ratio (SPR) of body tissues relative to water depends on the particle energy. For simplicity, however, most analytical dose planning systems do not account for SPR variation with particle energy along the beam's path, but rather assume a constant energy for SPR estimation. The range error due to this simplification could be indispensable depending on the particle species and the assumed energy. This error can be minimized by assuming a suitable energy referred to as an 'effective energy' in SPR estimation. To date, however, the effective energy has never been investigated for realistic patient geometries. We investigated the effective energies for proton, helium-, carbon-, and oxygen-ion radiotherapy using volumetric models of the reference male and female phantoms provided by the International Commission on Radiological Protection (ICRP). The range errors were estimated by comparing the particle ranges calculated when particle energy variations were and were not considered. The effective energies per nucleon for protons and helium, carbon, and oxygen ions were 70 MeV, 70 MeV, 131 MeV, and 156 MeV, respectively. Using the determined effective energies, the range errors were reduced to ?0.3 mm for respective particle species. For SPR estimation of multiple particle species, an effective energy of 100 MeV is recommended, with which the range error is ?0.5 mm for all particle species. PMID- 27694720 TI - Chagas disease prevalence in pregnant women: migration and risk of congenital transmission. AB - INTRODUCTION: Argentina has been a preferential target for Bolivian immigrants for decades. The relatively recent migratory flux includes Germany, France, the United States, Australia, Japan, and some Latin American countries. The aim of this cross-sectional study was to describe the prevalence of Chagas disease in pregnant women, analyzing the Bolivian-specific Chagas prevalence as the main contributor of migratory populations from Chagas disease-endemic areas to Buenos Aires city, Argentina, and to evaluate the impact of these migrant influxes on the process of the "urbanization" of the disease in reference hospital Jose Maria Ramos Mejia (JMRM). METHODOLOGY: Overall, 21,332 pregnant women (100%) between 15 and 49 years of age derived from the public maternity service of JMRMH were studied. Serology data was obtained from registered serological diagnosis data, consisting of three different serological tests performed at the Public Parasitology Unit. RESULTS: Although general prevalence decreased during the analyzed period, the specific prevalence of pregnant women from Bolivian origin showed a sustained growth during 1983-2013. Solely 5% of the total pregnant women population from Bolivia contributed to one third of the total Chagas prevalence. CONCLUSIONS: This study showed that a cohort of pregnant women from Bolivia who attended JMRMH during the period 1983-2007 constituted a population at risk for congenital transmission. Increased migration from endemic areas of Bolivia might potentially increase the prevalence of Chagas disease among pregnant women. In addition, this study highlights the importance to analyze specific prevalence according to endemic areas to determine the profiles of potential hidden prevalence. PMID- 27694721 TI - Prevalence of cutaneous warts in patients with systemic lupus erythematosus: a systematic review. AB - The aim of this study was to review and evaluate systematically the scientific evidence on the relationship between systemic lupus erythematosus (SLE) and cutaneous warts (CW) caused by human papillomavirus (HPV) infection. With strict inclusion and exclusion criteria, we extensively searched the PUBMED, BVS (Virtual Health Library), and SCOPUS databases for the studies that evaluated the prevalence of CW in patients with SLE. Secondary references were additionally obtained from the selected articles. Only four articles met the research criteria and showed a higher frequency of CW in SLE patients compared to healthy controls. One of them highlighted about rheumatoid factor (RF) in the sera of patients with SLE and found an inverse correlation between the occurrence of warts and RF autoantibody. Moreover, most of the selected articles showed that the presence of CW did not correlate with the use of immunosuppressive drugs. Therefore, these findings suggest that the prevalence of CW in patients with SLE is probably high due to the defects in immune mechanisms, independently of immunosuppressive drugs. PMID- 27694722 TI - Nosocomial coagulase-negative staphylococci in Belgrade: between Scylla and Charybdis. AB - INTRODUCTION: Coagulase-negative staphylococci (CoNS) are increasingly resistant nosocomial pathogens. We aimed to analyze the prevalence of CoNS isolates in clinical settings, the evolution of antimicrobial resistance of CoNS, and antibiotic consumption in a hospital. METHODOLOGY: This retrospective cohort study was carried out at a tertiary healthcare facility over 17 months. Identification of isolated cultures and antibiotic susceptibility testing were performed using the Vitek2 system. Of 1,217 isolates, 209 were obtained from 193 patients who had symptoms of nosocomial infections. Data were analyzed by descriptive statistics. Antibiotic consumption in the hospital is expressed in defined daily doses/100 patient days. RESULTS: Sixty-one percent of patients were admitted to the internal medicine ward, while others were admitted to the surgical ward. Forty-four percent of Gram-positive isolates were from wound swabs, and 26% were from blood. The predominant Gram-positive bacteria were CoNS. Antibiotic resistance of CoNS was highest against beta-lactam antibiotics, macrolides, and tetracyclines. Tigecycline, linezolid, and vancomycin produced the highest activities against CoNS in in vitro conditions, and consumption of linezolid and tigecycline increased in the same period. CONCLUSION: There are just a few remaining therapeutic options for the treatment of CoNS according to our results; vancomycin, linezolid, and tigecycline might be considered as first choice antibiotics, but such a hypothesis should be supported with a pharmacoeconomic analysis. Unfortunately, novel antimicrobial agents are still unavailable and/or too expensive in developing countries. However, inappropriate use of those antibiotics may lead to the rapid development of resistant strains in the near future. PMID- 27694723 TI - Antimicrobial susceptibility and vaginolysin in Gardnerella vaginalis from healthy and bacterial vaginosis diagnosed women. AB - INTRODUCTION: Bacterial vaginosis (BV) is a syndrome related to Gardnerella vaginalis and is characterized by an imbalance in the vaginal microbiota. This work focused on the evaluation of antimicrobial susceptibility patterns and the occurrence of the vaginolysin (vly) gene in G. vaginalis isolated from BV and non BV patients. METHODOLOGY: The vaginal secretions were collected randomly and processed for G. vaginalis isolation. The isolates were presumptively identified by beta-hemolysis and oxidase and catalase tests. Polymerase chain reaction (PCR) was performed to confirm bacterial identity and to detect the vly gene. Antimicrobial susceptibility patterns were determined. RESULTS: Of 89 patients, G. vaginalis was isolated from 42 (37 BV and 5 non-BV), and 204 isolates were selected (179 from BV and 25 non-BV). The vly gene was detected in all G. vaginalis isolated from non-BV women and in 98.3% of the bacteria from BV patients. High resistance was observed for ampicillin (54.4%), metronidazole (59.8%), tinidazole (60.3%) and secnidazole (71.6%). CONCLUSIONS: Further studies are needed to better address the role of G. vaginalis and the vly gene in BV pathogenesis. PMID- 27694724 TI - Prevalence and multidrug resistance of Escherichia coli from community-acquired infections in Lagos, Nigeria. AB - INTRODUCTION: The emergence of multidrug resistance (MDR; resistance to >= 2 more antimicrobials) in Escherichia coli is of concern due to complications encountered in treatment. METHODOLOGY: In this study, prevalence, antimicrobial resistance, and genetic characteristics of MDR community isolates of E. coli from Lagos, Nigeria were determined. Urine and stool samples were obtained from outpatients attending Lagos State hospitals and from animal handlers in abattoirs, poultries, and open markets, from December 2012 to July 2013. RESULTS: Approximately 50% of urine (200/394) and 88% of stool samples (120/136) were positive for E. coli. Based upon beta-lactamase production, a subset of those isolates was selected for further study. Of the 22 antimicrobials tested, E. coli exhibited resistance to all antimicrobials except amikacin and piperacillin/tazobactam. The highest levels of resistance were to tetracycline (182/247; 73.7%), trimethoprim/sulfamethoxazole (152/247; 61.5%), and ampicillin (147/247; 59.1%). Resistance to the cephalosporins ranged from 1.6%-15% including the third- and fourth-generation cephalosporins, cefpodoxime (20/247; 8.1%) and cefepime (4/247; 1.6%), respectively. MDR was observed in 69.6% (172/247) of the isolates. Forty-eight E. coli resistant to at least five antimicrobials were selected for further analysis using pulsed-field gel electrophoresis; seven distinct clusters were observed among the diverse patterns. Of the 48 MDR E. coli, 30 different sequence types (ST) were detected using multilocus sequence typing, including four ST131. CONCLUSIONS: This study demonstrated circulating MDR E. coli in the Nigerian community. Monitoring of antimicrobial resistance in developing countries is necessary to optimize empiric treatment and the prudent use of antimicrobials. PMID- 27694725 TI - Biofilm-forming and antimicrobial resistance traits of staphylococci isolated from goat dairy plants. AB - INTRODUCTION: Biofilm-associated antimicrobial resistance is of increasing importance to the maintenance and spread of foodborne pathogens in the food industry. This study aimed to investigate the ability to form biofilm and the antimicrobial resistance of staphylococci contaminating small-scale goat milk dairy plants. METHODOLOGY: Sixty isolates were tested for antimicrobial resistance against 20 drugs by the microdilution method. Biofilm-forming traits were assessed by the microtiter plate method (MtP), Congo red agar method (CRA), and icaD gene detection by polymerase chain reaction (PCR). RESULTS: High antimicrobial resistance to ampicillin (60/60; 100%), penicillin G (21/60; 35%), and erythromycin (15/60; 25%) was observed, but all isolates were susceptible to amoxicillin/K-clavulanate, ceftriaxone, ciprofloxacin, gentamicin, levofloxacin, linezolid, and moxifloxacin. No resistance to oxacillin or vancomycin was seen among Staphylococcus aureus. Twenty-seven isolates (27/60; 45%) were considered to form biofilm according to MtP, and similar biofilm-producing frequencies were observed in coagulase-negative staphylococci (CoNS) (20/44; 45.4%) and S. aureus (7/16; 43.7%). The icaD gene was observed only in S. aureus isolates. There was no association between biofilm production and antimicrobial resistance. A higher frequency of biofilm-producing staphylococci was found in isolates from bulk tank milk and hand swabs. On the other hand, isolates from pasteurized milk showed lower frequency of biofilm formation. CONCLUSIONS: Staphylococci contaminating goat dairy plants are potential biofilm producers. The results suggest no association between the ability to form biofilm and antimicrobial resistance. PMID- 27694726 TI - Seroprevalence of brucellosis in patients with prolonged fever in Bangladesh. AB - INTRODUCTION: This study describes the seroprevalence of human brucellosis among pyretic patients and detection of Brucella abortus DNA from seropositive pyretic patients using real-time polymerase chain reaction (rtPCR) for the first time in Bangladesh. METHODOLOGY: Blood samples were collected from 300 pyretic patients from October 2007 to May 2008 and subjected to three serological tests: Rose Bengal plate test (RBT), standard tube agglutination test (STAT), and indirect enzyme-linked immunosorbent assay (iELISA). Risk factors were identified by multivariate Firth's logistic regression analysis. Brucella genus (BCSP31) and species-specific (IS711) rtPCR were applied to six human sera samples. RESULTS: The seroprevalence of brucellosis among pyretic patients was estimated to be 2.0% (95% confidence interval [CI]: 0.74-4.30). The odds of brucellosis seropositivity were 8.9 (95% CI: 1.26-63.0) times higher in pyretic patients who handled goats than those who handled only cattle, whereas the odds of brucellosis seropositivity were 9.7 (95% CI: 1.28-73.68) times higher in pyretic patients who had backache compared to those without backache. B. abortus DNA was amplified from all six human sera that tested positive by RBT, STAT, and iELISA. As the agreement between the tests was very strong, RBT is recommended as a screening test for the diagnosis of human brucellosis in Bangladesh because it is easier to use, cheaper, and faster. CONCLUSIONS: Brucellosis among pyretic patients is common, and B. abortus is responsible for brucellosis in such patients. Pyretic patients who handle goats and those with backaches should be screened for brucellosis. PMID- 27694727 TI - Multidrug-resistant ESBL-producing Enterobacteriaceae and associated risk factors in community infants in Lebanon. AB - INTRODUCTION: Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL PE) infections are a growing threat to children, and the treatment of these infections becomes more and more challenging. A huge reservoir for ESBLs in the community is the fecal flora of children. This study investigates the rectal colonization, associated risk factors, antimicrobial susceptibility, and molecular characterization of ESBL-PE in Lebanese community infants. METHODOLOGY: A total of 117 rectal swabs were taken from healthy infants between 1 and 12 months of age. Detection of ESBLs was carried out using the double-disk synergy test, combination-disk method, and multiplex polymerase chain reaction (PCR). A questionnaire about the infant's history and risk factors for carrying ESBL-PE was administered. RESULTS: In total, 58 (49.6%) of 117 participants were ESBL-PE carriers. Some significant important risk factors for colonization in this study were male gender, hospital birth, caesarean delivery, and being formula-fed. Observed decrease in colonization rate was associated with intimate hygiene habits. Carriers of multiple bla genes were the most common. CTX-M type was the major harbored, gene and CTX-M-9 was the most predominant, followed by CTX-M-15 type. CONCLUSIONS: To the best of our knowledge, this is the first available data about the carriage rate of ESBL-PE in community infants in Lebanon and the Middle East, the first study showing that birth in hospital, caesarean delivery, and being formula-fed are all significantly associated risk factors for the high colonization rates in community - not hospitalized - infants, and showing the dominance of multiple resistance gene carriage and wide dissemination of CTX-M-9 ESBL. PMID- 27694728 TI - Molecular diagnosis of infectious diseases in Sao Miguel Island (Azores, Portugal): A hospital-based descriptive study. AB - INTRODUCTION: We performed a descriptive analysis of molecular diagnosis of infectious agents in the Sao Miguel Island population, in order to address questions like what is the frequency of clinical requests, is it observable seasonality of pathogens, and what is the positive rate for the clinical diagnosis. METHODOLOGY: This was a retrospective and descriptive study based on 878 individuals suspected of harboring infectious diseases during two consecutive years, 2012-2013. More than 25 different pathogens were investigated by polymerase chain reaction (PCR)-based methods. The individuals were stratified into gender, occupation, and age groups. RESULTS: The pathogen with more clinical requests was hepatitis C virus, investigated in 225 individuals (30.0%), followed by Leptospira spp., in 187 (24.9%). Overall, data demonstrated a gender distribution bias, where 72.9% of cases were males. The age group of 25 to 44 years was the class with more clinical requests. Regarding occupation, a predominance of construction workers (12.0%) was observed, followed by retired workers (11.0%). Patient distribution per year showed a higher number of patients in the fall months. Diagnoses of leptospirosis and respiratory virus infections presented seasonality. CONCLUSIONS: The present study provides a valid contribution to the knowledge of the epidemiology of infectious diseases in the Sao Miguel Island (Azores, Portugal) population.

AB - INTRODUCTION: Evaluating the attenuation of influenza viruses in animal studies is important in developing safe and effective vaccines. This study aimed to demonstrate that the microRNA (miRNA)-let-7b-mediated attenuated influenza viruses (miRT-H1N1) are sufficiently attenuated and safe in mice. METHODOLOGY: The pathogenicity of the miRT-H1N1virus was investigated in a mouse model, evaluated with median lethal dose (LD50). The replicative dynamics of the miRT H1N1, wild type (wt)-H1N1, and scramble (scbl)-H1N1 viruses in the lungs of infected mice were compared. The degrees of lesions and the expression levels of IL-6, TNF-alpha, and IFN-beta in the lungs of mice infected with different viruses were also analyzed. RESULTS: In miRT-H1N1 virus-infected mice, 100% of mice survived, and a lower pathogenicity was characterized with non-significant weight loss when compared to mice infected with the control wt virus. The miRT H1N1 virus was not fatal for mice, even at the highest dose administered. The viral load in the lungs of miRT-H1N1-infected mice was significantly lower than that of the wild-type virus-infected mice. Fewer pulmonary lesions and lower levels of selected pro-inflammatory cytokines in the lungs of the mice infected with the miRT-H1N1 virus were also observed. The virulence of the miRT-H1N1 virus reduced significantly, suggesting that the miRT-H1N1 virus was safe for mice. CONCLUSIONS: Our study demonstrated that the miRNA-mediated gene silencing is an alternative approach to attenuating the pathogenicity of wt influenza viruses that have potential in the development of influenza vaccines.

AB - INTRODUCTION: Use of intravenous heroin carries a risk of serious medical conditions, including acquiring blood-borne infections. Therefore, hepatitis B virus (HBV) and hepatitis C virus (HCV) infection represent a threat for people who inject drugs (PWID). The objectives of this study were to determine the extent and characteristics of risk factors for acquiring HBV and HCV infection in PWID included in opiate substitution treatment in the southern part of Bosnia and Herzegovina (B&H). METHODOLOGY: The study included 120 adult PWID of both sexes who participated in opiate substitution treatment. All participants were interviewed, and their blood samples were tested for the presence of the surface hepatitis B virus antigen (HBsAg) and hepatitis C virus antibodies (anti-HCV). Prevalence data were obtained and compared to the serological status. RESULTS: HBsAg prevalence among PWID was 0.8% (1/120), whereas seroprevalence of anti-HCV was 52.5% (63/120). PWID exposed to risk-behavior factors (such as unsafe sexual activity, serving prison sentence, and tattooing) were more frequently anti-HCV positive. Sharing drug paraphernalia was found to be the most significant risk factor. The highest predictive values for acquiring HCV-infection were attributed to PWID who used heroin for more than three years and who were unmarried. CONCLUSIONS: HBsAg prevalence among PWID is rare (0.8%), while HCV-infection (52.5%) presents an important health and social issue among PWID in B&H. Sharing drug paraphernalia and intravenous heroin use longer than three years were the most prominent risk-behavior factors among the patients we investigated. PMID- 27694731 TI - Effectiveness of tipranavir versus darunavir as a salvage therapy in HIV-1 treatment-experienced patients. AB - INTRODUCTION: Although both tipranavir (TPV) and darunavir (DRV) represent important options for the management of patients with multi-protease inhibitor (PI)-resistant human immunodeficiency virus (HIV), currently there are no studies comparing the effectiveness and safety of these two drugs in the Mexican population. The aim of this study was to compare the effectiveness of TPV versus DRV as a salvage therapy in HIV-1 treatment-experienced patients. METHODOLOGY: This was a comparative, prospective, cohort study. Patients with HIV and triple class drug resistance evaluated at the Hospital de Infectologia "La Raza", National Medical Center, were included. All patients had the protease and retrotranscriptase genotype; resistance mutation interpretation was done using the Stanford database. RESULTS: A total of 35 HIV-1 triple-class drug-resistant patients were analyzed. All of them received tenofovir and raltegravir, 22 received darunavir/ritonavir (DRV/r), and 13 received tipranavir/ritonavir (TPV/r) therapies. The median baseline RNA HIV-1 viral load and CD4+ cell count were 4.34 log (interquartile range [IQR], 4.15-4.72) and 267 cells/mm3 (IQR, 177 320) for the DRV/r group, and 4.14 log (IQR, 3.51-4.85) and 445 cells/mm3 (IQR, 252-558) for the TPV/r group. At week 24 of treatment, 91% of patients receiving DRV/r and 100% of patients receiving TPV/r had an RNA HIV-1 viral load < 50 copies/mL and a CD4+ cell count of 339 cells/mm3 (IQR, 252-447) and 556 cells/mm3 (IQR, 364-659), respectively. CONCLUSIONS: No significant difference was observed between DRV/r and TPV/r in terms of virological suppression in HIV-1 patients who were highly experienced in antiretroviral therapy. PMID- 27694732 TI - Molecular genotyping of duck hepatitis A viruses (DHAV) in Vietnam. AB - INTRODUCTION: The aim of this study was to identify the genetic characteristics and molecular genotyping of duck hepatitis A virus (DHAV) isolated in Vietnam during 2009-2013. METHODOLOGY: Thirty duckling livers from outbreaks between 2009 and 2013 in seven provinces were collected and identified by polymerase chain reaction (PCR). Then, VP1 genes of eleven positive samples and two attenuated vaccine strains were sequenced and analyzed. RESULTS: Genotypic and phylogenetic analyses indicated that the 13 Vietnamese isolates were classified into two genotypes, DHAV-1 and DHAV-3. The rate of identity and homology was 91%-100% between the 10 Vietnamese and 26 global strains of DHAV-3, and 92%-100% between 3 Vietnamese and 16 strains of DHAV-1. Between the DHAV-3 and DHAV-1 strains, the divergence reached 30%. At the C-terminal of VP1 for the different strains, a hypervariable region was observed, and notably, six of the Vietnamese DHAV-3 strains in this study showed four consistent differences (at positions T184M, Q200H, K207N, and K214R) within this group that were distinct from all other DHAV 3 strains. CONCLUSIONS: This is the first report of molecular characterization of DHAVs in Vietnam. At least two genotypes were identified, DHAV-1 and DHAV-3, with diversified clades within and between genotypes. DHAV-3 seemed to be dominant in Vietnam. PMID- 27694734 TI - Public knowledge, perceptions, and attitudes towards HIV/AIDS in Bahrain: A cross sectional study. AB - INTRODUCTION: HIV/AIDS is one of the major health problems worldwide. Despite the low prevalence of HIV in Bahrain, educational and awareness programs remain highly important in controlling and preventing the spread of the disease. This study aimed to assess the public's knowledge, risk perceptions, and attitudes towards HIV/AIDS in Bahrain. METHODOLOGY: A self-administered questionnaire-based survey was administered to and completed by 1,038 Bahraini adults. RESULTS: Although the average general awareness among participants was good (63%), some misconceptions and erroneous beliefs were common, including knowledge of mode of transmission and high risk groups. Participants' attitudes towards HIV/AIDS patients varied but were mostly negative; 60% of respondents agreed to isolating HIV/AIDS patients in workplaces and schools, and 52.4% of them thought that HIV is a divine punishment. The vast majority of the participants (84.4%) believed in the role of religion in limiting the spread of the disease. Though the local media was the least utilized source of information, the general opinion of the participants about the role of Bahraini government agencies and organizations in combating HIV/AIDS was positive. CONCLUSIONS: Though the Bahraini public had good knowledge about HIV/AIDS, there were misconceptions that need to be addressed. A major finding of this study was the negative attitudes towards HIV/AIDS patients. To have successful HIV control programs, negative attitudes towards HIV patients and the disease should be minimized. Existing and newly proposed health education and awareness program in Bahrain should address the issue of negative attitudes towards HIV/AIDS observed in this study. PMID- 27694733 TI - Monitoring of genotypic resistance profile in chronic hepatitis B patients receiving nucleos(t)ide analogues in Huzhou, China. AB - INTRODUCTION: Antiviral drug-resistance patterns of hepatitis B virus (HBV) mutants are complex and currently partly understood. The aim of this study was to monitor the genotypic resistance profile in patients with chronic hepatitis B (CHB) receiving nucleos(t)ide analogues (NAs) in Huzhou, eastern China. METHODOLOGY: Serum samples of 139 CHB patients undergoing NA treatment were obtained from Huzhou Central Hospital. The full-length HBV reverse transcriptase regions were amplified and sequenced. The NA resistance mutation positions, including rtL80, rtI169, rtV173, rtL180, rtA181, rtT184, rtA194, rtS202, rtM204, rtI233, rtN236, and rtM250 were analyzed. RESULTS: Genotypic resistance mutations were detected in 41.72% (58/139) of patients with CHB. Drug resistance mutations were detected at positions rt80, rt173, rt180, rt181, rt194, rt202, rt204, rt236, and rt250, but were not observed at positions rt169, rt184, and rt233. The prevalence of mutations at rtM204 was 54.44% in 90 patients who were treated with lamivudine (LAM) or telbivudine (LDT). RtN236 mutations were detected in 7.14% (2/28) of the patients receiving adefovir (ADV) therapy. Additionally, rtA181 mutations were observed in 4 patients with LAM, ADV, and LDT-based therapy, but not in those patients treated with entecavir (ETV). Among patients who harbored rtM204 combination mutations, rtM204I and rtM204V were significantly associated with rtL80I/V and rtL180M, respectively. CONCLUSIONS: The mutation patterns of NA resistant HBV are complicated in CHB patients in the current clinical setting. Thus, it is necessary to persistently monitor the resistance mutations of HBV for optimizing antiviral therapy strategy and for preventing an outbreak of clinical resistance. PMID- 27694735 TI - Intestinal parasitic infections and associated epidemiological drivers in two rural communities of the Bolivian Chaco. AB - INTRODUCTION: In 2013 a coproparasitological survey was carried out in two rural communities of the Bolivian Chaco to determine the prevalence of intestinal parasitic infections (IPIs) and to investigate on possible infection drivers through a questionnaire interview. METHODOLOGY: Faecal samples were examined by microscopy. Samples positive for Entamoeba histolytica complex and Blastocystis were molecularly examined to identify the species/subtypes involved. RESULTS: The overall infection rate was 86%, identical in both communities and mostly due to protozoa. Soil-transmitted helminths were detected in <3% of children and adults. DISCUSSION: The protozoa detected, including Blastocystis subtypes, indicate faecal contamination of the environment by both humans (as confirmed by the presence of Hymenolepis nana) and animals. Nested-PCR identified E. histolytica, thus signalling the possible occurrence of invasive amoebosis. Lack of safe water, environmental contamination, poor sanitation and hygiene, shared by both communities, are the main drivers of IPIs. In addition, unlike gender and socioeconomic factors, childhood (only for some species), crowding and cohabitation with animals proved to be further significant protozoon infection risk factors. CONCLUSIONS: These results highlight the need for the promotion of access to clean water, improved sanitation and better hygiene, thus reducing the frequency of preventive chemotherapy for STHs while continuing to monitor the population for possible recrudescence. PMID- 27694736 TI - Anti-proteolytic activity of Ganoderma lucidum methanol extract against Pseudomonas aeruginosa. AB - INTRODUCTION: Protease enzyme is considered one of the most serious virulence factors produced by extended-spectrum beta-lactamase-producing and multidrug resistant Pseudomonas aeruginosa (ESbetaLMDRPA) clinical isolates. METHODOLOGY: The antibacterial activity of methanol extract of Ganoderma lucidum fruiting bodies was tested against a protease-producing ESbetaLMDRPA clinical isolate, showing its mode of action. RESULTS: The extract showed high antibacterial activity. Its effect on purified protease indicated a reversible non-competitive protease inhibition (kis= 0.45 mg/mL). CONCLUSIONS: The G. lucidum extract could be a promising anti-proteolytic active against ESbetaLMDRPA. It may form a primary platform for further phytochemical studies and development of new drugs for therapy of skin burn infections. PMID- 27694737 TI - Relationships between low serum vitamin D levels and HBV "a" determinant mutations in chronic hepatitis B patients. AB - INTRODUCTION: Vitamin D is significantly associated with virus replication in chronic hepatitis B virus (HBV) infection. However, the relationship between low serum vitamin D levels and HBV "a" determinant mutations remains unknown. METHODOLOGY: A total of 133 chronically HBV-infected, treatment-naive patients were randomly selected in the present study. Serum vitamin D levels were measured by using liquid chromatography-mass spectrometry. The HBV "a" determinant was amplified, sequenced, and analyzed by nested polymerase chain reaction (PCR). RESULTS: Among 133 patients, 36, 88, and 9 patients had vitamin D deficiency (25(OH)D < 14 ng/mL), vitamin D insufficiency (25(OH)D >= 14 and < 30 ng/mL), and normal vitamin D serum levels ((25(OH)D >= 30 ng/mL), respectively. As results showed, 36 [11 genotype B HBVs (HBV/B) and 25 genotype C HBVs (HBV/C)] were isolated from the vitamin D-deficient group, 88 (48 HBV/B and 40 HBV/C) from the vitamin D-insufficient group, and 4 HBV/C strains from the normal serum-vitamin D group. Compared to the HBV/B infected patients with vitamin D insufficiency, higher rates of amino acid mutation within "a" determinant were detected in HBV/B infected, vitamin D-deficient patients. Moreover, the change frequency of M133 was 27.27% in HBV/B infected patients with vitamin D deficiency, which was significantly higher than those in the vitamin D-insufficient group (p = 0.040). CONCLUSIONS: Vitamin D deficiency is significantly associated with genotype B HBV "a" determinant mutations. PMID- 27694738 TI - Reflex threshold of signal-to-cut-off ratios of the Elecsys anti-HCV II assay for hepatitis C virus infection. AB - INTRODUCTION: Fast screening tests for hepatitis C virus (HCV) antibody often give false-positive results. Signal-to-cut-off (S/Co) ratios were suggested to be used as reflex confirmation of anti-HCV. The Elecsys Anti-HCV II assay is an effective test for the detection of hepatitis C, but no S/Co cutoff has been reported. The aim of this study was to determine the S/Co ratio threshold of anti HCV test using Elecsys Anti-HCV II screening and supplemental recombinant immunoblot assay (RIBA) test results as the gold standard. METHODOLOGY: A total of 36,341 serum samples were tested for HCV antibody using the Elecsys Anti-HCV II assay and 276 positive samples were then tested with supplemental RIBA (Mikrogen recomLine HCV IgG strip immunoassay). Receiver operation curve (ROC) analysis was used to determine the cutoff, sensitivity, and specificity of the optimal S/Co ratio. RESULTS: The Elecsys Anti-HCV II assay was positive (S/Co ratio >= 1) in 288 of the 36,341 samples (0.79%). RIBA testing on 276 of these 288 positive samples showed that all but one of 44 samples with an S/Co ratio of >= 1 and < 10 were negative, whereas the vast majority of samples (223/232, 96.1%) with an S/Co ratio >= 10 were positive. ROC analysis revealed that an optimal S/Co ratio cut-off value was 12.27. CONCLUSIONS: An S/Co ratio of 12.27 obtained with the Elecsys Anti-HCV II assay could be used as reflex confirmation of anti-HCV tests. PMID- 27694739 TI - Gut microbiota related to Giardia duodenalis, Entamoeba spp. and Blastocystis hominis infections in humans from Cote d'Ivoire. AB - INTRODUCTION: Literature data provide little information about protozoa infections and gut microbiota compositional shifts in humans. This preliminary study aimed to describe the fecal bacterial community composition of people from Cote d'Ivoire harboring Giardia duodenalis, Entamoeba spp., and Blastocystis hominis, in trying to discover possible alterations in their fecal microbiota structure related to the presence of such parasites. METHODOLOGY: Twenty fecal samples were collected from people inhabiting three different localities of Cote d'Ivoire for copromicroscopic analysis and molecular identification of G. duodenalis, Entamoeba spp., and B. hominis. Temporal temperature gradient gel electrophoresis (TTGE) was used to obtain a fingerprint of the overall bacterial community; quantitative polymerase chain reaction (qPCR) was used to define the relative abundances of selected bacterial species/group, and multivariate statistical analyses were employed to correlate all data. RESULTS: Cluster analysis revealed a significant separation of TTGE profiles into four clusters (p < 0.0001), with a marked difference for G. duodenalis-positive samples in relation to the others (p = 5.4*10-6). Interestingly, qPCR data showed how G. duodenalis-positive samples were related to a dysbiotic condition that favors potentially harmful species (such as Escherichia coli), while Entamoeba spp./B. hominis-positive subjects were linked to a eubiotic condition, as shown by a significantly higher Faecalibacterium prausnitzii-Escherichia coli ratio. CONCLUSIONS: This preliminary investigation demonstrates a differential fecal microbiota structure in subjects infected with G. duodenalis or Entamoeba spp./B. hominis, paving the way for using further next-generation DNA technologies to better understand host-parasite-bacteria interactions, aimed at identifying potential indicators of microbiota changes.

AB - BACKGROUND: Stem cell transplantation (SCT) places a heavy burden on the kidneys, often resulting in renal dysfunction or nephrotic syndrome. This study attempted to show that early-onset proteinuria predicts the development of overt nephropathy. METHODS: A total of 831 patients who received allogeneic SCT were surveyed. Excluding those with prior kidney disease and those lacking in an observation period >=1 year after SCT, 251 patients were eligible for the study. Dipstick proteinuria >=1+ within 1 year after SCT was defined as 'incident proteinuria', and subsequent persistence of an estimated glomerular filtration rate of <60 ml/min/1.73 m2 at 1 year or longer after SCT was defined as 'incident chronic kidney disease (CKD)'. Between-group differences were analyzed using the chi-square or Mann-Whitney U test. Factors associated with the incidence of CKD were investigated by multivariate Cox proportional regression analysis. Kidney biopsied tissue was examined in all nephrotic syndrome patients. RESULTS: The mean duration of follow-up was 4 years. Thirty-four (13.5%) and 66 (26.3%) patients developed incident proteinuria and incident CKD, respectively. Nine (3.6%) patients developed nephrotic syndrome mainly due to membranous nephropathy. The incidence of CKD was significantly greater in patients with incident proteinuria than those without (61.8 vs. 20.7%, p < 0.0001), and incident dipstick proteinuria was a significant risk for incident CKD (hazard ratio 4.39, 95% CI 2.44-7.73, p < 0.0001). CONCLUSION: SCT patients who manifest dipstick proteinuria are predisposed to overt nephropathy. Routine monitoring of the urine dipstick test is strongly recommended, as it facilitates early nephrology care for post-SCT patients. PMID- 27694744 TI - The Impact of Obesity on Outcomes Following Resection for Gastric Cancer. AB - BACKGROUND: Obesity is generally considered to be associated with increased postoperative morbidity and mortality following intraabdominal cancer surgery. However, recent reports showed that overweight patients may have a lower risk for adverse postoperative outcomes and this observation has been described as the 'obesity paradox'. Therefore, we aimed to analyze the impact of obesity on outcomes after resection for gastric cancer. METHODS: Data of patients who underwent resection for gastric cancer between 2005 and 2012 were assessed. Patient characteristics, postoperative outcomes and long-term survivals were compared between patients with body mass index (BMI) >=30 and <30. RESULTS: Resection for gastric cancer was performed in 249 patients. BMI >=30 was identified in 49 patients. Obese patients with BMI >=30 were more frequently diagnosed with diabetes (31 vs. 16%, p = 0.015). Resection for gastric cancer in obese patients was significantly associated with longer duration of surgery (278 vs. 243 min, p < 0.001), longer duration of hospital stay (18 vs. 16 days, p = 0.028), increased postoperative morbidity (49 vs. 33%, p = 0.037), and increased postoperative mortality (10 vs. 3%, p = 0.028). There was no significant difference in overall survival (OS) between patients with BMI >=30 and patients with BMI <30 (5-year OS rate: 59 vs. 62%, p = 0.587). CONCLUSION: Obesity may complicate resection for gastric cancer increasing the duration of surgical procedure, hospital stay and postoperative morbidity and mortality. However, BMI did not predict OS in our patients. Consequently, BMI may be too simple as a parameter to evaluate sophisticated interactions between different body fat compartments and inflammatory and immune responses and thus to predict long-term oncologic outcomes. PMID- 27694746 TI - Molecular Epidemiology of Human Metapneumovirus in Riyadh Province, Saudi Arabia. AB - Human metapneumovirus (HMPV) is an important cause of respiratory tract illness in children. Two HMPV subgroups, A and B, and four genotypes, A1, A2, B1 and B2, have been identified. Concurrent circulation of the different genotypes in yearly epidemics has been recorded globally, but not in Saudi Arabia. The current report was designed to study HMPV epidemiology in Saudi children and to analyze the genetic diversity and circulation patterns. Nasopharyngeal aspirates (n = 174) were collected from hospitalized children in Riyadh (2008-2009). The screening of samples using real-time RT-PCR identified 19 HMPV strains. The majority of the strains belonged to subgroup B, while all strains of subgroup A were members of genotype A2. In 2008, only subgroup B was recognized, whereas in 2009 both subgroups were identified to be cocirculating at similar rates. The full-length attachment (G) gene and a partial sequence of the fusion (F) gene of positive samples were sequenced. The G gene showed a high degree of genetic diversity and exhibited a variable number of positively selected sites in different lineages. In contrast, the F gene demonstrated an extensive genetic stability with a higher tendency toward purifying selection. This is the first report on HMPV genotype circulation in Saudi Arabia; however, the exact circulation kinetics requires further retrospective and prospective study. PMID- 27694747 TI - Language Development of Three- to Twelve-Year-Old Twins Compared to Singletons. AB - OBJECTIVE: The language development of twins tends to lag behind in comparison to that of singletons. The purpose of this study was to compare expressive and receptive language skills of 3- to 12-year-old twins with singletons. Secondly, correlations between language differences between twins and singletons and age were investigated. PATIENTS AND METHODS: Twenty-four twins with a mean age of 5.1 years participated in the study. The control group consisted of 24 singletons who were matched for gender and age. Language development was investigated using the Clinical Evaluation of Language Fundamentals. RESULTS: Twins scored significantly lower for expressive and receptive language skills compared to singletons. Even when excluding preterm-born children, twins still scored significantly lower for expressive language skills. There was no correlation between age and language differences between twins and their matched singletons. CONCLUSION: Twins score lower for expressive and receptive language skills compared to singletons, and preterm birth cannot be regarded as the main cause for the language delay. The language delay in twins is rather mild but does not seem to decrease with increasing age. PMID- 27694748 TI - Impact of Rectal Swabs on Infectious Complications after Transrectal Prostate Biopsy. AB - OBJECTIVES: To determine the impact of rectal swabs (RSs) on infectious complications (IC) following prostate biopsy (PB). METHODS: A retrospective cohort study was conducted including all patients subjected to PB between 2009 and 2013. Group B consisted of patients with a RS and group A of patients without. RS reported the presence of gram-positive or negative germs, sensitive or resistant to ciprofloxacin. Antimicrobial prophylaxis was adjusted to the result. Frequency of IC in each group was determined. RESULTS: Group B had 548 (47.20%) patients and group A 613 (52.80%). From group B, 250 (45.62%) of the RSs showed fluoroquinolone (FQ)-resistant germs. Forty nine (16.44%) patients with sensitive germs vs. 147 (59.51%) with resistant germs had a history of previous FQ treatment (p < 0.0001). IC were observed in 33 (5.49%) patients from group A and in 7 (1.28%) patients from group B (p < 0.0001), requiring hospitalization in 4.99 vs. 1.28%, respectively. IC and hospital admissions were reduced in 76.68 and 74.34%, respectively, following the implementation of RS. CONCLUSIONS: RS and targeted antibiotic prophylaxis prior to PB was associated with a significant reduction in IC and hospital admissions. Ceftriaxone could be an alternative in cases of known resistance. Past history of FQ treatment is associated with increased resistance. PMID- 27694741 TI - Advances in beta cell replacement and regeneration strategies for treating diabetes. AB - In the past decade, new approaches have been explored that are aimed at restoring functional beta cell mass as a treatment strategy for diabetes. The two most intensely pursued strategies are beta cell replacement through conversion of other cell types and beta cell regeneration by enhancement of beta cell replication. The approach closest to clinical implementation is the replacement of beta cells with human pluripotent stem cell-derived (hPSC-derived) cells, which are currently under investigation in a clinical trial to assess their safety in humans. In addition, there has been success in reprogramming developmentally related cell types into beta cells. Reprogramming approaches could find therapeutic applications by inducing beta cell conversion in vivo or by reprogramming cells ex vivo followed by implantation. Finally, recent studies have revealed novel pharmacologic targets for stimulating beta cell replication. Manipulating these targets or the pathways they regulate could be a strategy for promoting the expansion of residual beta cells in diabetic patients. Here, we provide an overview of progress made toward beta cell replacement and regeneration and discuss promises and challenges for clinical implementation of these strategies. PMID- 27694749 TI - Effects of Liraglutide and Vitamin E in Fructose-Induced Metabolic Syndrome in Rats. AB - BACKGROUND: Metabolic syndrome (MetS) is a growing worldwide health problem. However, there is yet no effective therapy for MetS. The present work investigated the effect of liraglutide, a synthetic glucagon-like peptide-1 and vitamin E on fructose-induced MetS in rats. SUMMARY: Liraglutide (0.3 mg/kg/day) and vitamin E (100 mg/kg/day) were administered either alone or in combination with high fructose-fed male rats for 6 weeks. Fructose-fed rats developed metabolic disorders assessed by visceral fat index, serum glucose, serum insulin, homeostasis model assessment-insulin resistance and serum lipids profile and hepatic disorders assessed by liver index, serum alanine aminotransferase and aspartate aminotransferase and steatohepatitis in histopathology. This study showed that liraglutide, vitamin E and their combination significantly ameliorated the fructose-induced metabolic and hepatic disorders. Key Messages: These results indicate a potential therapeutic benefit of liraglutide and vitamin E combination in prevention of MetS. Their protective effects might rely on their antioxidant effects as well as on the inhibition of tumor necrosis factor-alpha. PMID- 27694750 TI - Exposure of Piglets to Enteroviruses Investigated by an Immunoassay Based on the EV-G1 VP4 Peptide. AB - OBJECTIVE: The aim of this study was to investigate the exposure of piglets to enteroviruses-G (EV-G) through the presence of antibodies in their serum. METHODS: Serum samples were obtained from the vena cava of 10 piglets at 9 weeks of age and again 39 days later (day 39). They were tested using an immunoassay based on the EV-G1 VP4 peptide, since VP4 is highly conserved among the four Enterovirus capsid proteins, and by using a seroneutralization assay. RESULTS: For each serum collected on day 39 the optical density was high compared to the value obtained in serum collected earlier (p = 0.002). However, the titers of anti-EV-G1 serum neutralizing activity were not different in paired samples (p > 0.999). The sequence alignment of the EV-G1 VP4 peptide, encompassing 50 amino acids, used in the immunoassay showed 88% homology with EV-G, suggesting that antibodies directed toward other EV-G than EV-G1 may be detected. CONCLUSION: An immunoassay based on EV-G1 VP4 can detect an increased level of EV-G antibodies in piglet serum samples. Further studies are needed to determine whether this immunoassay may be useful for diagnosis and/or epidemiological studies and to monitor EV-G infection in pigs to evaluate strategies aimed to prevent enterovirus infections. PMID- 27694751 TI - Non-Responders to Intravitreal Ranibizumab in Subfoveal Choroidal Neovascularization Secondary to Age-Related Macular Degeneration. AB - AIM: Evaluation of the proportion of patients affected by subfoveal choroidal neovascularization secondary to age-related macular degeneration who are non respondent to intravitreal ranibizumab injections (IVRI). METHODS: Patients received 3 monthly IVRI, with monthly retreatments, in accordance with a pro re nata scheme (fluid on optical coherence tomography, leakage on fluorescein angiography, new haemorrhages). Non-responders were classified as follows: functional non-responder (best-corrected visual acuity worsening by a minimum of 2 ETDRS lines); anatomical non-responder (central foveal thickness not decreasing by at least 10% compared with baseline value); complete non-responder (both anatomical and functional non-responder criteria apply). PRIMARY OUTCOME MEASURE: identification of the proportion of non-responders. RESULTS: Four patients (7%) were functional non-responders at the 1-month examination, and 5, 5 and 7% at the 2-, 3- and 6-month examinations, respectively. Two of 4 initial non-responders were reclassified as responders during the 6-month follow-up. Twenty-three eyes (43%) were anatomical non-responders at the 1-month visit, and 32, 28 and 21% at 2, 3 and 6 months, respectively. Sixteen of 23 (70%) initially non-respondent eyes became respondent over the follow-up. Two eyes (4%) were classified as complete non-responders after 1 month. Non-responders amounted to 4, 0 and 2% at the 2-, 3- and 6-month examinations, respectively. No initially complete non responding eye remained so over the follow-up. CONCLUSION: Data indicate a low proportion of functional and anatomical non-responders to IVRI. Further studies are warranted providing a better definition of non-responder and a clearer picture of the magnitude of response, when present. PMID- 27694752 TI - Nerve Growth Factor Facilitates the Innervation of Perivascular Nerves in Tumor Derived Neovasculature in the Mouse Cornea. AB - BACKGROUND: Tumor neovascular vessels are not innervated by perivascular nerves. This study was an investigation of the effects of the nerve growth factor (NGF) on the distribution of perivascular nerves and neovessel formation in tumor tissues. METHODS: A gel containing DU145 prostate carcinoma cells or HT1080 fibrosarcoma cells was implanted into mouse corneas. NGF was subcutaneously administered using an osmotic mini-pump. The distribution of perivascular nerves in mouse corneas and densities of CD31-immunopositive neovessels and smooth muscles (alpha-smooth muscle actin, alpha-SMA) in tumor tissues were quantified. SUMMARY: Neovessels generated from corneal limber arteries in tumor tissues were observed 4-14 days after the implantation of tumor cells. The density of CD31 immunopositive cells in endothelium increased after the implantation of DU145 or HT1080 cells, while that of alpha-SMA-immunopositive cells slightly increased. The NGF treatment significantly increased the density of alpha-SMA- but not that of CD31-immunopositive cells (except for DU145 cells) and resulted in the innervation of perivascular nerves around tumor-derived neovessels, whereas no innervation was observed in the control group. Key Messages: These results suggest that NGF facilitates the innervation of perivascular nerves to regulate blood flow into tumor-derived neovessels.

AB - AIMS: The study aimed to determine whether the available literature supports a positive or negative influence of dialysis on regulatory T-cells (Tregs). METHODS: We performed a systematic search and a meta-analysis. Mean differences in Tregs number of chronic kidney disease stages G5 on dialysis patients (CKD G5D) and healthy controls (HCs) were compared. Random effects model was applied. The software used was general package for meta-analysis (version 4.3-0, depends R (>=2.9.1)). RESULTS: Five studies were included in the meta-analysis. The mean difference in percentage of Tregs on CD4+ T-cells between CKD G5D and HCs was not statistically different. Moreover, CKD GFR stages G5 not on dialysis (CKD G5) versus HC (p = 0.002; mean difference in Treg percentage was -2.47% in CKD G5 vs. HC) and CKD G5 versus CKD G5D (not significant). CONCLUSION: This meta-analysis demonstrates an association between the uremic state and lower Tregs, and supports the hypothesis that hemodialysis alter Tregs. Our findings highlight the need for new clinical studies. Video Journal Club 'Cappuccino with Claudio Ronco' at http://www.karger.com/?doi=449242. PMID- 27694754 TI - Liver Fibrosis and Body Mass Index Predict Hepatocarcinogenesis following Eradication of Hepatitis C Virus RNA by Direct-Acting Antivirals. AB - BACKGROUND AND AIMS: Predictive factors for hepatocarcinogenesis following eradication of hepatitis C virus (HCV) RNA by antiviral therapy with direct acting antivirals are unknown. Especially the impact of treatment with or without interferon on hepatocarcinogenesis is not clear. METHODS: A total of 958 patients with HCV genotype 1-related chronic liver disease and a sustained virological response defined as negative HCV RNA 24 weeks after cessation of antiviral therapy with direct-acting antivirals (triple therapy of NS3/4A protease inhibitor/peginterferon/ribavirin or all-oral combination therapy with NS3/4A protease inhibitor plus NS5A inhibitor) were included in a retrospective study. None of the patients had hepatocellular carcinoma before and during antiviral therapy. RESULTS: In all, 14 patients developed hepatocellular carcinoma during follow-up, and the development rate per 1,000 person-years was 7.35. The cumulative hepatocarcinogenesis rates were 4.2 and 4.2% at the end of 5 and 7 years, respectively. Multivariate analysis identified fibrosis 4 (FIB4) index (>=2.7) and body mass index (>=23.0) as determinants of hepatocarcinogenesis, but they did not identify the treatment regimen. In patients with a FIB4 index >=2.7, the hepatocarcinogenesis rates with the interferon regimen were not different from those for the regimen without interferon, regardless of gender. CONCLUSION: Liver fibrosis and body mass index, but not treatment regimen, are important predictors of hepatocarcinogenesis following eradication of HCV RNA by direct acting antivirals. PMID- 27694755 TI - Assessment of Uric Acid Level in the Saliva of Patients with Oral Lichen Planus. AB - OBJECTIVE: The aim of this study was to evaluate the level of uric acid (UA) in saliva, which is considered to be an antioxidant defense biomarker against oxidative stress in patients with oral lichen planus (OLP). SUBJECTS AND METHODS: In this case-control study, 25 OLP patients were included. The reticular form of OLP was verified by a clinical examination with Wickham striae, and other types (erosive, atrophic, ulcerative) were confirmed by histopathological assessment. Thirty healthy individuals matched for age and gender were selected as the control group. In both groups, the Navazesh technique was used to collect the unstimulated saliva. Then, the amount of UA was measured using a Cobas Mira autoanalyzer with a wavelength of 546 nm. The Student t test was used to analyze the data assuming a significance level at <0.05. RESULTS: Of the 25 patients, the most common type of OLP was erosive (n = 11, 44%), and the most common site of OLP was seen as bilateral in the buccal mucosa (n = 12, 48%). The mean level of salivary UA was significantly lower in the patients with OLP (2.10 +/- 0.19 mg/dL) in comparison with the control group (4.80 +/- 0.29 mg/dL; p < 0.001). CONCLUSION: In this study, OLP was associated with a decrease in UA levels in the saliva. Salivary UA as a biomarker could be used for monitoring and treating OLP. PMID- 27694756 TI - Exploring the Relationship between Sexual Compulsivity and Attentional Bias to Sex-Related Words in a Cohort of Sexually Active Individuals. AB - BACKGROUND/AIMS: If sexual compulsivity and other addictive behaviours share common aetiology, contemporary proposals about the role of attentional processes in understanding addictive behaviours are relevant. METHODS: To examine attentional biases for sex-related words among sexually active individuals and the relationship between sexual compulsivity and sexual behavioural engagement with attentional bias, 55 sexually active individuals completed a modified Stroop task and the sexual compulsivity scale. RESULTS: Findings showed attentional bias towards sex-related stimuli among sexually active participants. In addition, among those with low levels of sexual compulsivity, levels of attentional bias were the same across all levels of sexual experience. Among those with higher levels of sexual compulsivity, greater attentional bias was linked with lower levels of sexual experience. CONCLUSION: Attentional preference for concern related stimuli varies as a function of the interaction between how long a person has been active sexually and how compulsive their sexual behaviour is. PMID- 27694757 TI - The Prevalence of Tooth Wear in the Dutch Adult Population. AB - This study aimed to assess the prevalence of tooth wear in different age groups of the Dutch adult population and to determine this tooth wear distribution by gender, socioeconomic class, and type of teeth. Results were compared with the outcomes of a previous study in a comparable population. As part of a comprehensive investigation of the oral health of the general Dutch adult population in 2013, tooth wear was assessed among 1,125 subjects in the city of 's-Hertogenbosch. The data collected were subjected to stratified analysis by 5 age groups (25-34, 35-44, 45-54, 55-64, and 65-74 years), gender, socioeconomic class, and type of teeth. Tooth wear was assessed using a 5-point ordinal occlusal/incisal grading scale. The number of teeth affected was higher in older age groups. Men showed more tooth wear than women, and subjects with low socioeconomic status (low SES) showed on average higher scores than those with high SES. Tooth wear prevalence found in this study was higher in all age groups than in the previous study. The present study found prevalences of 13% for mild tooth wear and 80% for moderate tooth wear, leading to the conclusion that these are common conditions in the Dutch adult population. Severe tooth wear (prevalence 6%) may however be characterized as rare. A tendency was found for there to be more tooth wear in older age groups, in men as compared with women, in persons with lower SES, and in the present survey as compared with the previous one. PMID- 27694759 TI - Trends in Upper Tract Stone Disease in England: Evidence from the Hospital Episodes Statistics Database. AB - AIMS: The study aimed to determine the current trends in urolithiasis-related admissions and associated interventions in England between 2006/2007 and 2013/2014 utilizing Hospital Episode Statistics (HES) online data. MATERIAL AND METHODS: Data was extracted from the online HES data set for each year from 2006/2007 to 2013/2014 inclusive. Admissions and procedural interventions were identified from their corresponding OPCS-4 and ICD-10 codes. RESULTS: Finished consultant episodes (FCEs) for urolithiasis have increased by 20% over the last 7 years, with 93,039 FCEs in the year 2013/2014. Based on English population statistics, the lifetime prevalence of urolithiasis based on hospital-related admission/intervention data for 2013/2014 is 14%. The biggest increases were seen in those aged >=75 years (up by 51%, n = 2,853). Total interventions have increased from 28,624 to 42,068, with increased rates of shock wave lithotripsy (26%), ureteroscopy (URS; 86%) and percutaneous nephrolithotomy (149%). Emergency URS procedures have increased by 38%. Day-case rates for ureteric and renal URS, in 2013/2014, were 22 and 21%, respectively. CONCLUSIONS: Over the last 7 years, there is a rising prevalence of kidney stone disease with associated increase in the number of interventions related to it. Both elective and emergency URS procedures are increasing, with a rising trend for day-case URS. Similar trends are seen worldwide and future resource planning for urolithiasis is needed to match the increase in demand.

PMID- 27694758 TI - Study of hTERT and Histone 3 Mutations in Medulloblastoma. AB - Hotspot activating mutations of the telomerase reverse transcriptase (hTERT) promoter region were recently described in several tumor types. These mutations lead to enhanced expression of telomerase, being responsible for telomere maintenance and allowing continuous cell division. Additionally, there are alternative telomere maintenance mechanisms, associated with histone H3 mutations, responsible for disrupting the histone code and affecting the regulation of transcription. Here, we investigated the clinical relevance of these mechanistically related molecules in medulloblastoma. Sixty-nine medulloblastomas, formalin fixed and paraffin embedded, from a cohort of patients aged 1.5-70 years, were used to investigate the hotspot mutations of the hTERT promoter region, i.e. H3F3A and HIST1H3B, using Sanger sequencing. We successfully sequenced hTERT in all 69 medulloblastoma samples and identified a total of 19 mutated cases (27.5%). c.-124:G>A and c.-146:G>A mutations were detected, respectively, in 16 and 3 samples. Similar to previous reports, hTERT mutations were more frequent in older patients (p < 0.0001), being found only in 5 patients <20 years of age. In addition, hTERT-mutated tumors were more frequently recurrent (p = 0.026) and hTERT mutations were significantly enriched in tumors located in the right cerebellar hemisphere (p = 0.039). No mutations were found on the H3F3A or HIST1H3B genes. hTERT promoter mutations are frequent in medulloblastoma and are associated with older patients, prone to recurrence and located in the right cerebellar hemisphere. On the other hand, histone 3 mutations do not seem to be present in medulloblastoma. PMID- 27694761 TI - Understanding Bioluminescence in Dinoflagellates-How Far Have We Come? AB - Some dinoflagellates possess the remarkable genetic, biochemical, and cellular machinery to produce bioluminescence. Bioluminescent species appear to be ubiquitous in surface waters globally and include numerous cosmopolitan and harmful taxa. Nevertheless, bioluminescence remains an enigmatic topic in biology, particularly with regard to the organisms' lifestyle. In this paper, we review the literature on the cellular mechanisms, molecular evolution, diversity, and ecology of bioluminescence in dinoflagellates, highlighting significant discoveries of the last quarter of a century. We identify significant gaps in our knowledge and conflicting information and propose some important research questions that need to be addressed to advance this research field. PMID- 27694762 TI - Circadian Rhythms in Dinoflagellates: What Is the Purpose of Synthesis and Destruction of Proteins? AB - There is a prominent circadian rhythm of bioluminescence in many species of light emitting dinoflagellates. In Lingulodinium polyedrum a daily synthesis and destruction of proteins is used to regulate activity. Experiments indicate that the amino acids from the degradation are conserved and incorporated into the resynthesized protein in the subsequent cycle. A different species, Pyrocystis lunula, also exhibits a rhythm of bioluminescence, but the luciferase is not destroyed and resynthesized each cycle. This paper posits that synthesis and destruction constitutes a cellular mechanism to conserve nitrogen in an environment where the resource is limiting. PMID- 27694764 TI - The Genus Neoceratium (Planktonic Dinoflagellates) as a Potential Indicator of Ocean Warming. AB - Among the planktonic dinoflagellates, the species-rich genus Neoceratium has particularly remarkable features that include its easily recognizable outline and large size. This ubiquitous genus shows consistent presence in all plankton samples and has been a model for numerous studies since the end of the 19th century. It has already been described as a good candidate to monitor water masses and describe ocean circulation. We argue that the sensitivity displayed by Neoceratium to water temperature also makes it relevant as an indicator of ocean warming. The advantages and interests of using Neoceratium species to monitor climate change on a large scale are reassessed in view of recent advances in understanding their biology and ecology. PMID- 27694763 TI - Biology of the Marine Heterotrophic Dinoflagellate Oxyrrhis marina: Current Status and Future Directions. AB - Heterotrophic dinoflagellates are prevalent protists in marine environments, which play an important role in the carbon cycling and energy flow in the marine planktonic community. Oxyrrhismarina (Dinophyceae), a widespread heterotrophic dinoflagellate, is a model species used for a broad range of ecological, biogeographic, and evolutionary studies. Despite the increasing research effort on this species, there lacks a synthesis of the existing data and a coherent picture of this organism. Here we reviewed the literature to provide an overview of what is known regarding the biology of O. marina, and identify areas where further studies are needed. As an early branch of the dinoflagellate lineage, O. marina shares similarity with typical dinoflagellates in permanent condensed chromosomes, less abundant nucleosome proteins compared to other eukaryotes, multiple gene copies, the occurrence of trans-splicing in nucleus-encoded mRNAs, highly fragmented mitochondrial genome, and disuse of ATG as a start codon for mitochondrial genes. On the other hand, O. marina also exhibits some distinct cytological features (e.g., different flagellar structure, absence of girdle and sulcus or pustules, use of intranuclear spindle in mitosis, presence of nuclear plaque, and absence of birefringent periodic banded chromosomal structure) and genetic features (e.g., a single histone-like DNA-associated protein, cob-cox3 gene fusion, 5' oligo-U cap in the mitochondrial transcripts of protein-coding genes, the absence of mRNA editing, the presence of stop codon in the fused cob cox3 mRNA produced by post-transcriptional oligoadenylation, and vestigial plastid genes). The best-studied biology of this dinoflagellate is probably the prey and predators types, which include a wide range of organisms. On the other hand, the abundance of this species in the natural waters and its controlling factors, genome organization and gene expression regulation that underlie the unusual cytological and ecological characteristics are among the areas that urgently need study. PMID- 27694767 TI - An Updated List of Generic Names in the Thoracosphaeraceae. AB - Calcareous dinophytes produce exoskeletal calcified structures during their life history (a unique character among the alveolates) and are subsumed under the Thoracosphaeraceae as part of the Peridiniales. We provide a brief synopsis about the taxonomic history of the group, from the first descriptions of fossils in the 19th century through to the results of molecular phylogenetics studies undertaken during the past two decades. Delimitation and circumscription of the Thoracosphaeraceae are challenging, as they comprise both phototrophic (presumably including endosymbiotic) as well as heterotrophic (and even parasitic) dinophytes from marine and freshwater environments, respectively. However, calcareous structures are not known from all members of the Thoracosphaeraceae, and the corresponding species and groups are considered to have lost the capacity to calcify. Five years ago, a taxonomic list of 99 generic names assigned to the Thoracosphaeraceae was published, and we update this compendium with 19 additional names based on recent studies. PMID- 27694766 TI - Elements in the Development of a Production Process for Modified Vaccinia Virus Ankara. AB - The production of several viral vaccines depends on chicken embryo fibroblasts or embryonated chicken eggs. To replace this logistically demanding substrate, we created continuous anatine suspension cell lines (CR and CR.pIX), developed chemically-defined media, and established production processes for different vaccine viruses. One of the processes investigated in greater detail was developed for modified vaccinia virus Ankara (MVA). MVA is highly attenuated for human recipients and an efficient vector for reactogenic expression of foreign genes. Because direct cell-to-cell spread is one important mechanism for vaccinia virus replication, cultivation of MVA in bioreactors is facilitated if cell aggregates are induced after infection. This dependency may be the mechanism behind our observation that a novel viral genotype (MVA-CR) accumulates with serial passage in suspension cultures. Sequencing of a major part of the genomic DNA of the new strain revealed point mutations in three genes. We hypothesize that these changes confer an advantage because they may allow a greater fraction of MVA-CR viruses to escape the host cells for infection of distant targets. Production and purification of MVA-based vaccines may be simplified by this combination of designed avian cell line, chemically defined media and the novel virus strain. PMID- 27694768 TI - A Novel Bioinformatics Strategy to Analyze Microbial Big Sequence Data for Efficient Knowledge Discovery: Batch-Learning Self-Organizing Map (BLSOM). AB - With the remarkable increase of genomic sequence data of microorganisms, novel tools are needed for comprehensive analyses of the big sequence data available. The self-organizing map (SOM) is an effective tool for clustering and visualizing high-dimensional data, such as oligonucleotide composition on one map. By modifying the conventional SOM, we developed batch-learning SOM (BLSOM), which allowed classification of sequence fragments (e.g., 1 kb) according to phylotypes, solely depending on oligonucleotide composition. Metagenomics studies of uncultivable microorganisms in clinical and environmental samples should allow extensive surveys of genes important in life sciences. BLSOM is most suitable for phylogenetic assignment of metagenomic sequences, because fragmental sequences can be clustered according to phylotypes, solely depending on oligonucleotide composition. We first constructed oligonucleotide BLSOMs for all available sequences from genomes of known species, and by mapping metagenomic sequences on these large-scale BLSOMs, we can predict phylotypes of individual metagenomic sequences, revealing a microbial community structure of uncultured microorganisms, including viruses. BLSOM has shown that influenza viruses isolated from humans and birds clearly differ in oligonucleotide composition. Based on this host-dependent oligonucleotide composition, we have proposed strategies for predicting directional changes of virus sequences and for surveilling potentially hazardous strains when introduced into humans from non human sources. PMID- 27694765 TI - Transcription and Maturation of mRNA in Dinoflagellates. AB - Dinoflagellates are of great importance to the marine ecosystem, yet scant details of how gene expression is regulated at the transcriptional level are available. Transcription is of interest in the context of the chromatin structure in the dinoflagellates as it shows many differences from more typical eukaryotic cells. Here we canvas recent transcriptome profiles to identify the molecular building blocks available for the construction of the transcriptional machinery and contrast these with those used by other systems. Dinoflagellates display a clear paucity of specific transcription factors, although surprisingly, the rest of the basic transcriptional machinery is not markedly different from what is found in the close relatives to the dinoflagellates. PMID- 27694769 TI - Control of a Multi-Drug-Resistant Acinetobacter baumannii Outbreak after Orthopedics Department Relocation. AB - Acinetobacter baumannii clinical isolates have the ability to survive in the hospital niche for prolonged time periods and to develop resistance against multiple antimicrobial agents. Therefore, A. baumannii has emerged as an important cause of nosocomial outbreaks worldwide, especially in critical-care environments such as intensive care units. In the present communication, we report a multi-drug-resistant A. baumannii outbreak that occurred in an orthopedics department in Greece after the admission of a patient previously hospitalized in the intensive care unit of a Greek tertiary care hospital. Despite the implementation of infection control measures, 29 patients were infected, significantly raising their hospitalization periods and treatment costs. Interestingly, the outbreak was put under control after the department's previously programmed relocation. PMID- 27694770 TI - Molecular Quantification and Genetic Diversity of Toxigenic Fusarium Species in Northern Europe as Compared to Those in Southern Europe. AB - Fusarium species produce important mycotoxins, such as deoxynivalenol (DON), nivalenol (NIV) and T-2/HT-2-toxins in cereals. The highest DON and T-2/HT-2 toxin levels in northern Europe have been found in oats. About 12%-24% of Finnish oat samples in 2012 contained >1.75 mg.kg-1 of DON, which belongs to type B trichothecenes. Fusarium graminearum is the most important DON producer in northern Europe and Asia and it has been displacing the closely related F. culmorum in northern Europe. The 3ADON chemotype of F. graminearum is dominant in most northern areas, while the 15ADON chemotype of F. graminearum is predominating in Central and southern Europe. We suggest that the northern population of F. graminearum may be more specialized to oats than the southern population. Only low levels of F. culmorum DNA were found in a few oat samples and no correlation was found between F. culmorum DNA and DON levels. DNA levels of F. graminearum were in all cases in agreement with DON levels in 2011 and 2012, when DON was measured by gas chromatography-mass spectrometry (GC-MS). When the RIDA(r)QUICK SCAN kit results (DON) were compared to DNA levels of F. graminearum, the variation was much higher. The homogenization of the oats flour by grinding oats with 1 mm sieve seems to be connected to this variation. There was a significant correlation between the combined T-2 and HT-2 and the combined DNA levels of F. langsethiae and F. sporotrichioides in Finland in 2010-2012. PMID- 27694771 TI - Macroalgal Endophytes from the Atlantic Coast of Canada: A Potential Source of Antibiotic Natural Products? AB - As the need for new and more effective antibiotics increases, untapped sources of biodiversity are being explored in an effort to provide lead structures for drug discovery. Endophytic fungi from marine macroalgae have been identified as a potential source of biologically active natural products, although data to support this is limited. To assess the antibiotic potential of temperate macroalgal endophytes we isolated endophytic fungi from algae collected in the Bay of Fundy, Canada and screened fungal extracts for the presence of antimicrobial compounds. A total of 79 endophytes were isolated from 7 species of red, 4 species of brown, and 3 species of green algae. Twenty of the endophytes were identified to the genus or species level, with the remaining isolates designated codes according to their morphology. Bioactivity screening assays performed on extracts of the fermentation broths and mycelia of the isolates revealed that 43 endophytes exhibited antibacterial activity, with 32 displaying antifungal activity. Endophytic fungi from Bay of Fundy macroalgae therefore represent a significant source of antibiotic natural products and warrant further detailed investigation. PMID- 27694772 TI - Temporal Variation of Mycotoxin Producing Fungi in Norwegian Cereals. AB - Spring barley is grown on about half of the Norwegian cereal area. The rest of the area is equally divided between wheat and oats. Most years the domestic production provides 70%-80% of the domestic market for bread wheat. Barley and oats are mainly grown for animal feed. During the years 2008-2012, severe epidemics of Fusarium head blight have led to increased mycotoxin contamination of cereals. During that period, precipitation was above normal during anthesis and grain maturation. The most important mycotoxin producers have been F. avenaceum, F. culmorum, F. graminearum and F. langsethiae. Increased deoxynivalenol contamination of Norwegian cereals during recent years is due to severe F. graminearum epidemics. PMID- 27694773 TI - Sad State of Phage Electron Microscopy. Please Shoot the Messenger. AB - Two hundred and sixty publications from 2007 to 2012 were classified according to the quality of electron micrographs; namely as good (71); mediocre (21); or poor (168). Publications were from 37 countries; appeared in 77 journals; and included micrographs produced with about 60 models of electron microscopes. The quality of the micrographs was not linked to any country; journal; or electron microscope. Main problems were poor contrast; positive staining; low magnification; and small image size. Unsharp images were frequent. Many phage descriptions were silent on virus purification; magnification control; even the type of electron microscope and stain used. The deterioration in phage electron microscopy can be attributed to the absence of working instructions and electron microscopy courses; incompetent authors and reviewers; and lenient journals. All these factors are able to cause a gradual lowering of standards. PMID- 27694774 TI - Towards an Ecological Understanding of Dinoflagellate Cyst Functions. AB - The life cycle of many dinoflagellates includes at least one nonflagellated benthic stage (cyst). In the literature, the different types of dinoflagellate cysts are mainly defined based on morphological (number and type of layers in the cell wall) and functional (long- or short-term endurance) differences. These characteristics were initially thought to clearly distinguish pellicle (thin walled) cysts from resting (double-walled) dinoflagellate cysts. The former were considered short-term (temporal) and the latter long-term (resting) cysts. However, during the last two decades further knowledge has highlighted the great intricacy of dinoflagellate life histories, the ecological significance of cyst stages, and the need to clarify the functional and morphological complexities of the different cyst types. Here we review and, when necessary, redefine the concepts of resting and pellicle cysts, examining both their structural and their functional characteristics in the context of the life cycle strategies of several dinoflagellate species. PMID- 27694775 TI - Emergence of Algal Blooms: The Effects of Short-Term Variability in Water Quality on Phytoplankton Abundance, Diversity, and Community Composition in a Tidal Estuary. AB - Algal blooms are dynamic phenomena, often attributed to environmental parameters that vary on short timescales (e.g., hours to days). Phytoplankton monitoring programs are largely designed to examine long-term trends and interannual variability. In order to better understand and evaluate the relationships between water quality variables and the genesis of algal blooms, daily samples were collected over a 34 day period in the eutrophic Lafayette River, a tidal tributary within Chesapeake Bay's estuarine complex, during spring 2006. During this period two distinct algal blooms occurred; the first was a cryptomonad bloom and this was followed by a bloom of the mixotrophic dinoflagellate, Gymnodinium instriatum. Chlorophyll a, nutrient concentrations, and physical and chemical parameters were measured daily along with phytoplankton abundance and community composition. While 65 phytoplankton species from eight major taxonomic groups were identified in samples and total micro- and nano-phytoplankton cell densities ranged from 5.8 * 106 to 7.8 * 107 cells L-1, during blooms, cryptomonads and G. instriatum were 91.6% and 99.0%, respectively, of the total phytoplankton biomass during blooms. The cryptomonad bloom developed following a period of rainfall and concomitant increases in inorganic nitrogen concentrations. Nitrate, nitrite and ammonium concentrations 0 to 5 days prior were positively lag-correlated with cryptomonad abundance. In contrast, the G. insriatum bloom developed during periods of low dissolved nitrogen concentrations and their abundance was negatively correlated with inorganic nitrogen concentrations. PMID- 27694776 TI - Effect of Electrical Stimulation on Fruit Body Formation in Cultivating Mushrooms. AB - The effect of high-voltage electrical stimulation on fruit body formation in cultivating mushrooms was evaluated using a compact pulsed power generator designed and based on an inductive energy storage system. An output voltage from 50 to 130 kV with a 100 ns pulse width was used as the electrical stimulation to determine the optimum amplitude. The pulsed high voltage was applied to a sawdust based substrate of Lyophyllum decastes and natural logs hosting Lentinula edodes, Pholiota nameko, and Naematoloma sublateritium. The experimental results showed that the fruit body formation of mushrooms increased 1.3-2.0 times in terms of the total weight. The accumulated yield of Lentinula edodes for four cultivation seasons was improved from 160 to 320 g by applying voltages of 50 or 100 kV. However, the yield was decreased from 320 to 240 g upon increasing the applied voltage from 100 to 130 kV. The yield of the other types of mushrooms showed tendencies similar to those of Lentinula edodes when voltage was applied. An optimal voltage was confirmed for efficient fruit body induction. The hypha activity was evaluated by the amount of hydrophobin release, which was mainly observed before the fruit body formation. The hydrophobin release decreased for three hours after stimulation. However, the hydrophobin release from the vegetative hyphae increased 2.3 times one day after the stimulation. PMID- 27694777 TI - A Comparative Overview of the Flagellar Apparatus of Dinoflagellate, Perkinsids and Colpodellids. AB - Dinoflagellates are a member of the Alveolata, and elucidation of the early evolution of alveolates is important for our understanding of dinoflagellates, and vice versa. The ultrastructure of the flagellar apparatus has been described from several dinoflagellates in the last few decades, and the basic components appear to be well conserved. The typical dinoflagellate apparatus is composed of two basal bodies surrounded by striated collars attached to a connective fiber. The longitudinal basal body is connected to a longitudinal microtubular root (LMR; equivalent of R1) and single microtubular root (R2), whereas the transverse basal body is connected to a transverse microtubular root (TMR; R3) and transverse striated root (TSR) with a microtubule (R4). Some of these components, especially the connective fibers and collars, are dinoflagellate specific characteristics that make their flagellar apparatus relatively complex. We also compare these structures with the flagellar apparatus from a number of close relatives of dinoflagellates and their sister, the apicomplexans, including colpodellids, perkinsids, and Psammosa. Though the ultrastructural knowledge of these lineages is still relatively modest, it provides us with an interesting viewpoint of the character evolution of the flagellar apparatus among those lineages. PMID- 27694778 TI - Lubricin in synovial fluid of mild and severe temporomandibular joint internal derangements. AB - BACKGROUND: To understand the molecular basis of temporomandibular joint (TMJ) pathologies, we aimed to investigate the lubricin levels in the TMJ synovial fluid (SF) of patients with mild to severe internal derangements (IDs). MATERIAL AND METHODS: A total, 34 joints were the study group. Only patients, with a Wilkes stage of III, IV and V were included, in this sample. Control group consisted of SF from eight joints, from patients undergoing to orthognatic surgery. Concentrations of lubricin in the SF from both samples were measured using ELISA system. RESULTS: The mean lubricin concentration was 7.029 +/- 0.21 ug/mL in stage III patients; 5.64 +/- 0.10 ug/mL in stage IV patients, and 4.78 +/- 0.11 ug/mL in stage V patients. The lubricin levels from stage IV and stage V patients differed significantly (P <= 0.001) from those of control subjects. Lubricin levels were inversely correlated with age and to VAS score. CONCLUSIONS: The results of this cross-sectional study highlight the relationship between disease severity and the levels of lubricin in TMJ SF. Our findings suggest that novel biotherapeutic approaches, including the administration of recombinant lubricin in the joint cavity, for the treatment of TMJ diseases can be developed.

AB - BACKGROUND: The cancer which appears in the mobile portion of the tongue is the most common neoplasm of the oral cavity. The objective of this study was to analyse oral tongue cancer epidemiology in a population of 610 patients diagnosed between 1990 and 2008 and detailed in the Tumour Registry of the Madrid region. MATERIAL AND METHODS: A retrospective analysis based on the following variables provided in the Tumour Registry was achieved: age, gender, histology, stage, location, treatment. Descriptive and analytic statistics with these variables, using Pearson's Chi-square test to study the relationship between the qualitative variables. RESULTS: Patients' mean age was 61.53+/-13.95 years, with a gender ratio of 2.09:1 (413 males vs 197 females). The lesion was mainly localized in the lateral border of tongue, with other sites (dorsal face, ventral face, lingual tonsil, contiguous sites, tongue NOS) represented at lower rates. Squamous cell carcinomas (94.9%) far outweighted other histologies (salivary gland tumours, soft tissue tumours, haematolymphoid tumours). 59% of the cases appeared in localized stages, versus 35.2% in regional and 4.8% in distant stages. Surgery was the most frequently used treatment, followed by surgery in combination with radiotherapy. CONCLUSIONS: Oral tongue cancer is a disease of the elderly, with a male predominance. It mainly appears in its lateral border, localized squamous cell carcinomas representing the great majority of lingual neoplasms. PMID- 27694780 TI - Dabigatran: A new oral anticoagulant. Guidelines to follow in oral surgery procedures. A systematic review of the literature. AB - BACKGROUND: Dabigatran is a newly commercialized drug that is replacing other anticoagulants in the prevention of venous thromboembolism, stroke and systemic arterial valve embolism. It acts directly on thrombin presenting in a dynamic and predictable way, which does not require monitoring these patients. Therefore, we consider the need to assess whether their use increases the risk of bleeding involved before any dental treatment. MATERIAL AND METHODS: We performed a systematic review with a bibliographic search in PubMed/Medline along with the Cochrane Library. We excluded articles dealing with all anticoagulants other than dabigatran, and works about surgical treatments in anatomical locations other than the oral cavity. RESULTS: We included a total of 13 papers of which 1 was a randomized clinical trial, 9 narrative literature reviews, 1 case series, 2 clinical cases and 1 expert opinion. Because we did not obtain any properly designed clinical trials, we were unable to conduct a meta-analysis. CONCLUSIONS: Currently, there is no consensus on the procedure to be followed in patients taking dabigatran. However, all authors agree to treat each case individually in accordance to the risk of embolism, postoperative bleeding and renal function. Also, it is necessary to perform minimally invasive interventions, and take the appropriate local anti-hemolytic measures. PMID- 27694782 TI - Temporomandibular chronic dislocation: The long-standing condition. AB - BACKGROUND: The temporomandibular joint (TMJ) dislocation can be categorised into three groups: acute, habitual or recurrent and long-standing. The long-standing or protracted lower jaw dislocation refers to a condition that persists for more than one month without reduction. There are a great variety of methods for its treatment, from the manual or non-surgical, to surgical ones like the indirect approach (conservative surgical approach) and direct approach (open joint). Additional procedures in unsuccessful cases may include extra-articular orthognathic techniques to correct a malocclusion until joint replacement. MATERIAL AND METHODS: We report four new cases with a minimum of 6 weeks dislocation who were seen since 1995 to 2015 in the Maxillofacial Department of the Clinico Hospital (Valencia, Spain), in which the mean age was 57.5 years. Most of them were bilateral and the gender was predominantly female. Additionally, we have reviewed the related literature. RESULTS: All of the cases were successfully treated and half of them required open surgery. CONCLUSIONS: The report confirms the difficulty of the treatment and reaffirms the necessity to bear in mind the wide variety of methods available for the treatment of this pathology. We stress the difficulties associated with managing the treatment and of suggesting new guidelines. The best option still remains not to delay the diagnostic and to select the appropriate initial treatment. PMID- 27694781 TI - Analysis of potential dynamic concealed factors in the difficulty of lower third molar extraction. AB - BACKGROUND: The purpose of this study was to identify potential concealed variables associated with the difficulty of lower third molar (M3) extractions. MATERIAL AND METHODS: To address the research purpose, we implemented a prospective study and enrolled a sample of subjects presenting for M3 removal. Predictor variables were categorized into Group-I and Group-II, based on predetermined criteria. The primary outcome variable was the difficulty of extraction, measured as extraction time. Appropriate univariate and multivariate statistics were computed using ordinal logistic regression. RESULTS: The sample comprised of 1235 subjects with a mean age of 29.49 +/- 8.92 years in Group-I and 26.20 +/- 11.55 years in Group-II subjects. The mean operating time per M3 extraction was 21.24 +/- 12.80 and 20.24 +/- 12.50 minutes for Group-I and Group II subjects respectively. Three linear parameters including B-M2 height (distance between imaginary point B on the inferior border of mandibular body, and M2), lingual cortical thickness, bone density and one angular parameter including Rc Cs angle (angle between ramus curvature and curve of spee), in addition to patient's age, profile type, facial type, cant of occlusal plane, and decreased overbite, were found to be statistically associated ( p < or = 0.05) with extraction difficulty under regression models. CONCLUSIONS: In conclusion, our study indicates that the difficulty of lower M3 extractions is possibly governed by morphological and biomechanical factors with substantial influence of myofunctional factors. PRACTICAL IMPLICATIONS: Preoperative evaluation of dynamic concealed factors may not only help in envisaging the difficulty and planning of surgical approach but might also help in better time management in clinical practice. PMID- 27694783 TI - Local vs general anaesthesia in the development of neurosensory disturbances after mandibular third molars extraction: A retrospective study of 534 cases. AB - BACKGROUND: The choice of the anaesthetic modality is one of the primary steps during planning of third molar surgery. The aim of the present study was to compare the risk of developing neurological injures of the inferior alveolar nerve (IAN) and lingual nerve (LN) in patients treated for wisdom teeth removal under general anaesthesia (GA) with a group treated under local anaesthesia (LA). MATERIAL AND METHODS: This is an observational retrospective, unicentric study; between September 2013 and September 2014, 534 patients underwent third molar surgery, 194 (36,3%) under GA and 340 (63,7%) under LA by the same oral surgeon. Difference in the incidence of IAN and LN injures between groups have been statistically analyzed with Fisher exact test and estimated odd ratio for development of such complications has been calculated. RESULTS: In GA patients the incidence of IAN and LN injures was 4.6% and 2.1%, respectively while in the LA group it was and 0.3% and 0%, respectively. A significant difference in IAN and LN involvement between groups was observed (IAN lesion: Fisher exact test, p<0.001; LN lesions: Fisher exact test, p<0.05). The estimated odd ratio for development of IAN injures after GA was 16.49 (95% CI: 2.07-131.19) and was not calculable for LN injures because no cases were observed in the LA group. CONCLUSIONS: Since GA is a perioperative variable that seems to significantly increase the risk of developing IAN and LN lesions, when treating patients that request GA, they must be adequately informed that an higher incidence of post surgical sensory disturbances is expected. PMID- 27694784 TI - Myogenic temporomandibular disorders: Clinical systemic comorbidities in a female population sample. AB - BACKGROUND: Myogenic temporomandibular disorders (MTMD) frequently coexist with other clinical conditions in the same individual. In the last decades, several authors have analyzed these comorbidities looking for the origin of this overlapping. Objetives: The aim of this study was to perform a comparative anaylisis between a group of patients with MTMD and a control group of dental patients without dysfunctional pathology to assess whether there are significant differences in the presence of systemic medical comorbidities between the two groups. MATERIAL AND METHODS: Restrospective epidemiological analysis, based on medical questionnaires in a group of 31 patients, women, aged from 24 to 58 (average 39.96 years), diagnosed with MTMD (Masticatory Myofascial Pain), with a control group with the same number of individuals, gender and age range to evaluate if there is a significant statistical difference in the presence of medical comorbidities in this group of patients with MTMD and if they are in a higher risk of suffering different pathological conditions. RESULTS: It was found that the group affected by MTMD presented many more associated medical conditions than the control group: health changes during the last year, medical evaluations and treatments, presence of pain, sinus disease, tinnitus, headache, joint pain, ocular disorders, fatigue, dizziness, genitourinary disorders and xerostomia among others; and they were also in a higher risk to suffer other pathological entities as headaches and articular pain. CONCLUSIONS: These results reinforce our hypothesis that MTMD belong to a group of medical conditions triggered by a loss of equilibrium of the individual's Psycho-Neuro-Endocrine-Immune (PNEI) Axis that produces alterations in the response against external stimuli in some genetically predisposed individuals. It is, therefore, necessary to change the way of diagnosing and managing these individual's medical conditions, being mandatory to look from a more multidisciplinary perspective than the one we are currently offering. PMID- 27694785 TI - Retrospective study of the bone morphology in the posterior mandibular region. Evaluation of the prevalence and the degree of lingual concavity and their possible complications. AB - BACKGROUND: In order to choose the appropriate implant size and to prevent complications, an oral surgeon must know the size and shape of the mandible. In the posterior mandibular region, a lingual undercut is often found and could represent a difficulty hard to manage if a lingual or buccal perforation occur. A large series of computed tomography (CT) images of the mandibular first molar was evaluated and the bone morphology, the prevalence and the degree of the lingual concavity in the first molar region were studied. MATERIAL AND METHODS: One hundred and fifty-one computed tomography (CT) examinations of patients were retrospectively evaluated to determine anatomical variations in bone morphology in the submandibular fossa region. RESULTS: A total of 151 subjects were included, consisting of 64 males (M) (42.4%) and 87 females (F) (57.6%). The under-cut type ridge was present in 64.2% of the cases. The concavity angle was 66.6 +/- 8.9 degrees (M) and 71.6 +/- 8.4 degrees (F) and the linear concavity depth 4.5 +/- 2.3 mm (M) and 3.1 +/- 1.7 mm (F) (p>0.05). CONCLUSIONS: Mandibles with any lingual concavity present a potential increased risk of lingual cortical perforation during implant placement surgery. CT imaging allows characterizing the anatomy of the submandibular fossa and provides other important information for the preoperative assessment of the posterior mandible for dental implants placement. PMID- 27694786 TI - Radial free forearm flap versus pectoralis major pedicled flap for reconstruction in patients with tongue cancer: Assessment of quality of life. AB - BACKGROUND: This study investigated the quality of life of Chinese patients with tongue cancer who had undergone immediate flap reconstruction surgery. In addition, we compared 2 groups of patients: those who had received radial forearm free flap (RFFF) surgery and others who had received pectoralis major myocutaneous flap (PMMF) surgery. MATERIAL AND METHODS: Patients who received RFFF or PMMF reconstruction after primary tongue cancer treated with total and subtotal tongue resection were eligible for the current study. The patients' demographic data, medical history, and quality of life scores (14-item Oral Health Impact Profile (OHIP-14) and the University of Washington Quality of Life (UW-QOL) questionnaires) were collected. RESULTS: A total of 41 of 63 questionnaires were returned (65.08%). There were significant differences between the 2 groups in the gender (p< .05). Patients reconstructed with RFFF performed better in the shoulder domains, in addition to worse appearance domains. CONCLUSIONS: Using either RFFF or PMMF for reconstruction of defects after tongue cancer resection significantly influences a patient's quality of life. Data from this study provide useful information for physicians and patients during their discussion of reconstruction modalities for tongue cancers. PMID- 27694787 TI - Oral health and quality of life in the municipal senior citizen's social clubs for people over 65 of Valencia, Spain. AB - BACKGROUND: The world population is aging considerably. The state of elderly's dentition is poor. Many authors agree that the oral health status influence the elderly's quality of life.The objective of our study was to analyze the relation between the oral health status and the general health status through the quality of life of elderly people aged 65 years or more in Valencia, Spain. MATERIAL AND METHODS: A cross-sectional oral health survey and an oral examination have been designed to study an elderly population. There were 202 adults (103 men and 99 women). Age: 65 years of age and over. Randomly selected senior citizen's social clubs. The Oral Health Impact Profile (OHIP-14) has been used to obtain the health survey. Moreover, the EuroQol-5d and a Visual Analogue Scale (VAS) have been the tools to obtain the general health status. Finally, sociodemographic and oral health questions have been needed. RESULTS: Descriptive and inferential results have been done and the main results are the following, the mean additive score of the OHIP-14 was 8.88, the mean value of the EuroQol-5d was 0.58 and of the VAS, 72.90. The OHIP-14 was consistently and significantly correlated with the index EuroQol-5d and with variables such as number of teeth, missing teeth, DMFT, dental status (being or not edentulous) and occupation. The EuroQol-5d was related to dental habits, sex, income, systemic pathologies and filled teeth. CONCLUSIONS: The oral health has a high impact on quality of life. The oral health and the general health are closely related. The oral hygiene and getting toothless influence negatively on the quality of life of elderly people. PMID- 27694788 TI - Impacted maxillary canines and root resorption of adjacent teeth: A retrospective observational study. AB - BACKGROUND: The prevalence of impacted maxillary canine is reported to be between 1% and 3%. The lack of monitoring and the delay in the treatment of the impacted canine can cause different complications such as: displacement of adjacent teeth, loss of vitality of neighbouring teeth, shortening of the dental arch, follicular cysts, canine ankylosis, recurrent infections, recurrent pain, internal resorption of the canine and the adjacent teeth, external resorption of the canine and the adjacent teeth, combination of these factors. An appropriate diagnosis, accurate predictive analysis and early intervention are likely to prevent such undesirable effects. The objective is to evaluate, by means of a retrospective observational study, the possibility of carrying out a predictive analysis of root resorption adjacent to the impacted canines by means of orthopantomographs, so as to limit the prescription of additional 3D radiography. MATERIAL AND METHODS: 120 subjects with unilateral or bilateral maxillary impacted canine were examined and 50 patients with 69 impacted maxillary canine (22 male, 28 female; mean age: 11.7 years) satisfied the inclusion criteria of the study. These patients were subjected to a basic clinical and radiographic investigation (orthopantomographs and computerized tomography). All panoramic films were viewed under standardized conditions for the evaluation of two main variables: maxillary canine angulations (a, b, g angles) and the overlapping between the impacted teeth and the lateral incisor (Analysis of Lindauer). Binary logistic regression was used to estimate the likelihood of resorbed lateral incisors depending on sector location and angle measurements. RESULTS: Results indicated that b angle has the greatest influence on the prediction of root resorption (predictive value of b angle = 76%). If beta angle <18 degrees and Lindauer = I, the probability of resorption is 0.06. CONCLUSIONS: Evaluation of b angle and superimposition lateral incisor/impacted canine analysed on orthopantomographs could be one of the evaluation criteria for prescribing second level examination (CT and CTCB) and for detecting root resorption of impacted maxillary canine adjacent teeth. PMID- 27694789 TI - Surgical complications in zygomatic implants: A systematic review. AB - BACKGROUND: The use of zygomatic implants in the prosthetic rehabilitation of the patient with severe maxillary bone atrophy is another therapeutic alternative, not exempt from complications. The main objective of this review is to analyze and describe the most frequent surgical complications associated with the use of zygomatic implants. MATERIAL AND METHODS: An electronic database search on PubMed, along with a manual search, without taking into account date nor language, was undertaken by two observers, selecting studies that comprised a study period from 6 to 12 months, any type of clinical trial, and series that included a follow-up and/or review period during the aforementioned margin, that mentioned at least two types of complications. RESULTS: Out of the initial search that yielded 455 studies, 67 were considered potentially relevant for the present study, out of which 14 were finally selected. Out of the most frequent surgical complications, sinusitis (3,9%) and failure in osseointegration (2,44%) are highlighted. CONCLUSIONS: The analysis of the results shows that the most frequent complications are sinusitis and failure in osseointegration of the zygomatic implant. However, a standardised data collection system for the data on complications is needed. PMID- 27694790 TI - Distance of the alveolar antral artery from the alveolar crest. Related factors and surgical considerations in sinus floor elevation. AB - BACKGROUND: In a variable proportion of maxillary sinuses alveolar antral artery is located close to the residual ridge, increasing the chances for haemorrhagic complications during sinus floor elevation procedures. MATERIAL AND METHODS: Retrospective observational study of CBCT explorations performed for implant treatment planning. The upper first molar area was selected for this study. The relative uncertainty (standard deviation of the measurement divided by its mean and expressed as a percentage from 0% to 100%) was chosen for determining the observational errors. For modeling the chances of AAA detection, the generalized additive models (GAM) approach was chosen. RESULTS: A total of 240 maxillary sinuses were studied (46.25% males) whose median median age was 58 years old (IQR: 52-66). Univariate models showed that the chances for an AAA-alvelar crest distance <=15mm increase in wider sinuses with lower, subsinusally edentulous crests. When distance is considered as a continuous variable, the best mutivariate model showed an explained deviance of 67% and included AAA diameter, distance AAA-sinus floor, sinus width, and shape, height and width of the residual ridge. Thinner AAAs are found closer to the crest (within the <=15mm safe distance). CONCLUSIONS: Bearing in mind the inclusion criteria and the limitations of this investigation, it is concluded that there is a high proportion of maxillary sinuses where AAA describes a course close to the alveolar crest (<=15mm), which was classically considered a safe distance for SFE. This position is related to the presence of atrophic crests (depressed ridge form) and wide maxillary sinuses where the distance of the vessel to the floor of the sinus is small. This information may permit a better surgical planning of SFE procedures. PMID- 27694791 TI - Cancer and orofacial pain. AB - BACKGROUND: Cancer pain is a devastating condition. Pain in the orofacial region, may be present as the single symptom of cancer or as a symptom of cancer in its later stages. This manuscript revises in a comprehensive manner the content of the conference entitled "Orofacial Pain and Cancer" (Dolor Orofacial y Cancer) given at the VI Simposio International "Advances in Oral Cancer" on the 22 July, 2016 in San Sebastioan-Donostia, Spain. MATERIAL AND METHODS: We have reviewed (pubmed-medline) from the most relevant literature including reviews, systematic reviews and clinical cases, the significant and evidence-based mechanisms and mediators of cancer-associated facial pain, the diverse types of cancers that can be present in the craniofacial region locally or from distant sites that can refer to the orofacial region, cancer therapy that may induce pain in the orofacial region as well as discussed some of the new advancements in cancer pain therapy. RESULTS: There is still a lack of understanding of cancer pain pathophysiology since depends of the intrinsic heterogeneity, type and anatomic location that the cancer may present, making more challenging the creation of better therapeutic options. Orofacial pain can arise from regional or distant tumor effects or as a consequence of cancer therapy. CONCLUSIONS: The clinician needs to be aware that the pain may present the characteristics of any other orofacial pain disorder so a careful differential diagnosis needs to be given. Cancer pain diagnosis is made by exclusion and only can be reached after a thorough medical history, and all the common etiologies have been carefully investigated and ruled out. The current management tools are not optimal but there is hope for new, safer and effective therapies coming in the next years. PMID- 27694792 TI - Effect of miRNA-27a and Leptin Polymorphisms on Risk of Recurrent Spontaneous Abortion. AB - BACKGROUND The aim of this study was to investigate the possible associations of miRNA-27a and Leptin polymorphisms with the risk of recurrent spontaneous abortion (RSA). MATERIAL AND METHODS Between May 2013 and April 2015 at Shenzhen Longhua New District Central Hospital, we randomly recruited 138 RSA patients as the case group and another 142 normal pregnancy women as the control group. We used denaturing high-performance liquid chromatography (DHPLC) to determine the genotypes and allele frequencies of miRNA-27a rs895819 A/G and Leptin rs7799039 G/A. RESULTS The GG genotype and G allele frequencies of miRNA-27a rs895819 A/G were higher in the case group than in the control group, and the AA genotype and A allele frequencies of Leptin rs7799039 G/A were also higher in the case group than in the control group (all P<0.05). MiRNA-27a rs895819 A/G and Leptin rs7799039 G/A polymorphisms increased the risk of RSA (Exp (B)=2.732, 95% CI=1.625~4.596, P=0.000; Exp (B)=4.081, 95% CI=1.817~9.164, P=0.001). GG-AA or AG AA carriers had a higher risk of RSA. The miRNA-27a expression of AA carriers of miRNA-27a rs895819 was lower than that of AG+GG carriers both in the case and control groups (all P=0.024). The plasma leptin concentration of GG carriers was lower than that of GA+AA carriers in the case group (P=0.026). CONCLUSIONS The polymorphisms of miRNA-27a rs895819 A/G and Leptin rs7799039 G/A may contribute to an increased risk of RSA. PMID- 27694793 TI - Y-27632 Increases Sensitivity of PANC-1 Cells to EGCG in Regulating Cell Proliferation and Migration. AB - BACKGROUND The study aimed to investigate the inhibitory effect of (1R,4r)-4-((R) 1-aminoethyl)-N-(pyridin-4-yl) cyclohexanecarboxamide (Y-27632) and (-) epigallocatechin-3-gallate (EGCG) on the proliferation and migration of PANC-1 cells. EGCG, found in green tea, has been previously shown to be one of the most abundant and powerful catechins in cancer prevention and treatment. Y-27632, a selective inhibitor of rho-associated protein kinase 1, is widely used in treating cardiovascular disease, inflammation, and cancer. MATERIAL AND METHODS PANC-1 cells, maintained in Dulbecco's Modified Eagle's Medium, were treated with dimethyl sulfoxide (control) as well as different concentrations (20, 40, 60, and 80 MUg/mL) of EGCG for 48 h. In addition, PANC-1 cells were treated separately with 60 MUg/mL EGCG, 20 MUM Y-27632, and EGCG combined with Y-27632 (60 MUg/mL EGCG + 20 MUM Y-27632) for 48 h. The effect of EGCG and Y-27632 on the proliferation and migration of PANC-1 cells was evaluated using Cell Counting Kit 8 and transwell migration assays. The expression of peroxisome proliferator activated receptor alpha (PPARalpha) and Caspase-3 mRNA was determined by Quantitative real-time polymerase chain reaction (RT-qPCR). RESULTS EGCG (20-80 MUg/mL) inhibited cell viability in a dose-dependent manner. Y-27632 enhanced the sensitivity of PANC-1 cells to EGCG (by increasing the expression of PPARa and Caspase-3 mRNA) and suppressed cell proliferation. PANC-1 cell migration was inhibited by treatment with a combination of EGCG and Y-27632. CONCLUSIONS Y 27632 increases the sensitivity of PANC-1 cells to EGCG in regulating cell proliferation and migration, which is likely to be related to the expression of PPARa mRNA and Caspase-3 mRNA. PMID- 27694794 TI - Long Non-Coding RNA (LncRNA) Urothelial Carcinoma Associated 1 (UCA1) Increases Multi-Drug Resistance of Gastric Cancer via Downregulating miR-27b. AB - BACKGROUND In this study, we aimed to investigate the association between UCA1 and miR-27b in gastric cancer and further study their involvement in multi-drug resistance (MDR) of gastric cancer. MATERIAL AND METHODS The microarray data of dysregulated lncRNAs in gastric cancer tissues was retrieved in the GEO dataset. QRT-PCR analysis was performed to assess UCA1 expression based on 28 paired cancerous and peritumoral normal tissues. The human gastric cancer cell line SGC 7901, and SGC-7901 derived Adriamycin (doxorubicin) resistant SGC-7901/ADR, cisplatin resistant SGC-7901/DDP, and 5-FU resistant SGC-7901/FU cells were used as in vitro cell models to assess the effect of UCA1 and miR-27b on MDR. RESULTS UCA1 was significantly upregulated in the cancerous tissues and its expression was negatively correlated with miR-27b expression level. Inhibition of UCA1 significantly restored miR-27b expression in MDR gastric cancer cells. UCA1 knockdown and miR-27b overexpression reduced IC50 of ADR, DDP, and 5-FU in SGC 7901/ADR cells and increased ADR induced cell apoptosis. UCA1 overexpression and miR-27b inhibition increased the IC50 of ADR, DDP, and 5-FU in SGC-7901 cells and reduced ADR induced cell apoptosis. Western blot analysis showed that UCA1 knockdown and miR-27b overexpression also decreased anti-apoptotic protein BCL-2 and increased apoptotic protein cleaved caspase-3. CONCLUSIONS UCA1 is negatively correlated with miR-27b expression in gastric cancer tissue. Knockdown of UCA1 restored miR-27b expression in gastric cancer cells. The UCA1-miR-27b axis was involved in regulation of chemosensitivity of gastric cancer cells. PMID- 27694795 TI - Valve-in-Valve Replacement Using a Sutureless Aortic Valve. AB - BACKGROUND We present a unique case of a 61-year-old female patient with homograft deterioration after redo surgery for prosthetic valve endocarditis with root abscess. CASE REPORT The first operation was performed for type A dissection with root, arch, and elephant trunk replacement of the thoracic aorta. The present re-redo surgery was performed as valve-in-valve with a sutureless aortic bioprosthesis. The postoperative course was uneventful and the patient was discharged on day 6. CONCLUSIONS The current case report demonstrates that sutureless bioprostheses are an attractive option for surgical valve-in-valve procedures, which can reduce morbidity and mortality. PMID- 27694796 TI - Mild Hypothermia Protects Pigs' Gastric Mucosa After Cardiopulmonary Resuscitation via Inhibiting Interleukin 6 (IL-6) Production. AB - BACKGROUND The purpose of this study was to determine the effect of mild hypothermia therapy on gastric mucosa after cardiopulmonary resuscitation (CPR) and the underlying mechanism. MATERIAL AND METHODS Ventricular fibrillation was induced in pigs. After CPR, the surviving pigs were divided into mild hypothermia treated and control groups. The changes in vital signs and hemodynamic parameters were monitored before cardiac arrest and at intervals of 0.5, 1, 2, 4, 6, 12, and 24 h after restoration of spontaneous circulation. Serum IL-6 was determined at the same time, and gastroscopy was performed. The pathologic changes were noted, and the expression of IL-6 was determined by hematoxylin and eosin (HE) staining and immunohistochemistry under light. RESULTS The heart rate, mean arterial blood pressure, and cardiac output in both groups did not differ significantly. The gastric mucosa ulcer index evaluated by gastroscopy 2 h and 24 h after restoration of spontaneous circulation (ROSC) in the mild hypothermic group was lower than that the control group (P<0.05). The inflammatory pathologic score of gastric mucosa in the mild hypothermic group 6-24 h after ROSC was lower than that in the control group (P<0.05). Serum and gastric mucosa IL-6 expression 0.5 4 h and 6, 12, and 24 h after ROSC was lower in the mild hypothermic group than in the control group (P<0.05). CONCLUSIONS Mild hypothermia treatment protects gastric mucosa after ROSC via inhibiting IL-6 production and relieving the inflammatory reaction. PMID- 27694797 TI - Excess of mutational jackpot events in expanding populations revealed by spatial Luria-Delbruck experiments. AB - The genetic diversity of growing cellular populations, such as biofilms, solid tumours or developing embryos, is thought to be dominated by rare, exceptionally large mutant clones. Yet, the emergence of these mutational jackpot events is only understood in well-mixed populations, where they stem from mutations that arise during the first few cell divisions. To study jackpot events in spatially structured populations, we track mutant clones in microbial populations using fluorescence microscopy and population sequencing. High-frequency mutations are found to be massively enriched in microbial colonies compared with well-shaken liquid cultures, as a result of late-occurring mutations surfing at the edge of range expansions. Thus, jackpot events can be generated not only when mutations arise early but also when they occur at favourable locations, which exacerbates their role in adaptation and disease. In particular, because spatial competition with the wild type keeps most mutant clones in a quiescent state, strong selection pressures that kill the wild type promote drug resistance. PMID- 27694798 TI - Interference-driven spacer acquisition is dominant over naive and primed adaptation in a native CRISPR-Cas system. AB - CRISPR-Cas systems provide bacteria with adaptive immunity against foreign nucleic acids by acquiring short, invader-derived sequences called spacers. Here, we use high-throughput sequencing to analyse millions of spacer acquisition events in wild-type populations of Pectobacterium atrosepticum. Plasmids not previously encountered, or plasmids that had escaped CRISPR-Cas targeting via point mutation, are used to provoke naive or primed spacer acquisition, respectively. The origin, location and order of spacer acquisition show that spacer selection through priming initiates near the site of CRISPR-Cas recognition (the protospacer), but on the displaced strand, and is consistent with 3'-5' translocation of the Cas1:Cas2-3 acquisition machinery. Newly acquired spacers determine the location and strand specificity of subsequent spacers and demonstrate that interference-driven spacer acquisition ('targeted acquisition') is a major contributor to adaptation in type I-F CRISPR-Cas systems. Finally, we show that acquisition of self-targeting spacers is occurring at a constant rate in wild-type cells and can be triggered by foreign DNA with similarity to the bacterial chromosome. PMID- 27694799 TI - Enzymatic hydrolysis by transition-metal-dependent nucleophilic aromatic substitution. AB - Nitroaromatic compounds are typically toxic and resistant to degradation. Bradyrhizobium species strain JS329 metabolizes 5-nitroanthranilic acid (5NAA), which is a molecule secreted by Streptomyces scabies, the plant pathogen responsible for potato scab. The first biodegradation enzyme is 5NAA aminohydrolase (5NAA-A), a metalloprotease family member that converts 5NAA to 5 nitrosalicylic acid. We characterized 5NAA-A biochemically and obtained snapshots of its mechanism. 5NAA-A, an octamer that can use several divalent transition metals for catalysis in vitro, employs a nucleophilic aromatic substitution mechanism. Unexpectedly, the metal in 5NAA-A is labile but is readily loaded in the presence of substrate. 5NAA-A is specific for 5NAA and cannot hydrolyze other tested derivatives, which are likewise poor inhibitors. The 5NAA-A structure and mechanism expand our understanding of the chemical ecology of an agriculturally important plant and pathogen, and will inform bioremediation and biocatalytic approaches to mitigate the environmental and ecological impact of nitroanilines and other challenging substrates. PMID- 27694801 TI - Polyketide and nonribosomal peptide retro-biosynthesis and global gene cluster matching. AB - Polyketides (PKs) and nonribosomal peptides (NRPs) are profoundly important natural products, forming the foundations of many therapeutic regimes. Decades of research have revealed over 11,000 PK and NRP structures, and genome sequencing is uncovering new PK and NRP gene clusters at an unprecedented rate. However, only ~10% of PK and NRPs are currently associated with gene clusters, and it is unclear how many of these orphan gene clusters encode previously isolated molecules. Therefore, to efficiently guide the discovery of new molecules, we must first systematically de-orphan emergent gene clusters from genomes. Here we provide to our knowledge the first comprehensive retro-biosynthetic program, generalized retro-biosynthetic assembly prediction engine (GRAPE), for PK and NRP families and introduce a computational pipeline, global alignment for natural products cheminformatics (GARLIC), to uncover how observed biosynthetic gene clusters relate to known molecules, leading to the identification of gene clusters that encode new molecules. PMID- 27694800 TI - Functional mining of transporters using synthetic selections. AB - Only 25% of bacterial membrane transporters have functional annotation owing to the difficulty of experimental study and of accurate prediction of their function. Here we report a sequence-independent method for high-throughput mining of novel transporters. The method is based on ligand-responsive biosensor systems that enable selective growth of cells only if they encode a ligand-specific importer. We developed such a synthetic selection system for thiamine pyrophosphate and mined soil and gut metagenomes for thiamine-uptake functions. We identified several members of a novel class of thiamine transporters, PnuT, which is widely distributed across multiple bacterial phyla. We demonstrate that with modular replacement of the biosensor, we could expand our method to xanthine and identify xanthine permeases from gut and soil metagenomes. Our results demonstrate how synthetic-biology approaches can effectively be deployed to functionally mine metagenomes and elucidate sequence-function relationships of small-molecule transport systems in bacteria.

AB - Diphthamide and the tRNA wobble uridine modifications both require diphthamide biosynthesis 3 (Dph3) protein as an electron donor for the iron-sulfur clusters in their biosynthetic enzymes. Here, using a proteomic approach, we identified Saccharomyces cerevisiae cytochrome b5 reductase (Cbr1) as a NADH-dependent reductase for Dph3. The NADH- and Cbr1-dependent reduction of Dph3 may provide a regulatory linkage between cellular metabolic state and protein translation. PMID- 27694802 TI - Oligosaccharyltransferase inhibition induces senescence in RTK-driven tumor cells. AB - Asparagine (N)-linked glycosylation is a protein modification critical for glycoprotein folding, stability, and cellular localization. To identify small molecules that inhibit new targets in this biosynthetic pathway, we initiated a cell-based high-throughput screen and lead-compound-optimization campaign that delivered a cell-permeable inhibitor, NGI-1. NGI-1 targets oligosaccharyltransferase (OST), a hetero-oligomeric enzyme that exists in multiple isoforms and transfers oligosaccharides to recipient proteins. In non small-cell lung cancer cells, NGI-1 blocks cell-surface localization and signaling of the epidermal growth factor receptor (EGFR) glycoprotein, but selectively arrests proliferation in only those cell lines that are dependent on EGFR (or fibroblast growth factor, FGFR) for survival. In these cell lines, OST inhibition causes cell-cycle arrest accompanied by induction of p21, autofluorescence, and cell morphology changes, all hallmarks of senescence. These results identify OST inhibition as a potential therapeutic approach for treating receptor-tyrosine-kinase-dependent tumors and provides a chemical probe for reversibly regulating N-linked glycosylation in mammalian cells. PMID- 27694805 TI - Transfer of optical orbital angular momentum to a bound electron. AB - Photons can carry angular momentum, not only due to their spin, but also due to their spatial structure. This extra twist has been used, for example, to drive circular motion of microscopic particles in optical tweezers as well as to create vortices in quantum gases. Here we excite an atomic transition with a vortex laser beam and demonstrate the transfer of optical orbital angular momentum to the valence electron of a single trapped ion. We observe strongly modified selection rules showing that an atom can absorb two quanta of angular momentum from a single photon: one from the spin and another from the spatial structure of the beam. Furthermore, we show that parasitic ac-Stark shifts from off-resonant transitions are suppressed in the dark centre of vortex beams. These results show how light's spatial structure can determine the characteristics of light-matter interaction and pave the way for its application and observation in other systems. PMID- 27694804 TI - N-acetylglucosamine sensing by a GCN5-related N-acetyltransferase induces transcription via chromatin histone acetylation in fungi. AB - N-acetylglucosamine (GlcNAc) exists ubiquitously as a component of the surface on a wide range of cells, from bacteria to humans. Many fungi are able to utilize environmental GlcNAc to support growth and induce cellular development, a property important for their survival in various host niches. However, how the GlcNAc signal is sensed and subsequently transduced is largely unknown. Here, we identify a gene that is essential for GlcNAc signalling (NGS1) in Candida albicans, a commensal and pathogenic yeast of humans. Ngs1 can bind GlcNAc through the N-terminal beta-N-acetylglucosaminidase homology domain. This binding activates N-acetyltransferase activity in the C-terminal GCN5-related N acetyltransferase domain, which is required for GlcNAc-induced promoter histone acetylation and transcription. Ngs1 is targeted to the promoters of GlcNAc inducible genes constitutively by the transcription factor Rep1. Ngs1 is conserved in diverse fungi that have GlcNAc catabolic genes. Thus, fungi use Ngs1 as a GlcNAc-sensor and transducer for GlcNAc-induced transcription. PMID- 27694806 TI - Dog and human inflammatory bowel disease rely on overlapping yet distinct dysbiosis networks. AB - Inflammatory bowel disease (IBD) is an autoimmune condition that is difficult to diagnose, and animal models of this disease have questionable human relevance1. Here, we show that the dysbiosis network underlying IBD in dogs differs from that in humans, with some bacteria such as Fusobacterium switching roles between the two species (as Bacteroides fragilis switches roles between humans and mice)2. For example, a dysbiosis index trained on humans fails when applied to dogs, but a dog-specific dysbiosis index achieves high correlations with the overall dog microbial community diversity patterns. In addition, a random forest classifier trained on dog-specific samples achieves high discriminatory power, even when using stool samples rather than the mucosal biopsies required for high discriminatory power in humans2. These relationships were not detected in previously published dog IBD data sets due to their limited sample size and statistical power3. Taken together, these results reveal the need to train host specific dysbiosis networks and point the way towards a generalized understanding of IBD across different mammalian models. PMID- 27694807 TI - Methylotrophic methanogenesis discovered in the archaeal phylum Verstraetearchaeota. AB - Methanogenesis is the primary biogenic source of methane in the atmosphere and a key contributor to climate change. The long-standing dogma that methanogenesis originated within the Euryarchaeota was recently challenged by the discovery of putative methane-metabolizing genes in members of the Bathyarchaeota, suggesting that methanogenesis may be more phylogenetically widespread than currently appreciated. Here, we present the discovery of divergent methyl-coenzyme M reductase genes in population genomes recovered from anoxic environments with high methane flux that belong to a new archaeal phylum, the Verstraetearchaeota. These archaea encode the genes required for methylotrophic methanogenesis, and may conserve energy using a mechanism similar to that proposed for the obligate H2-dependent methylotrophic Methanomassiliicoccales and recently described Candidatus 'Methanofastidiosa'. Our findings indicate that we are only beginning to understand methanogen diversity and support an ancient origin for methane metabolism in the Archaea, which is changing our understanding of the global carbon cycle.

PMID- 27694811 TI - Dairy and plant based food intakes are associated with altered faecal microbiota in 2 to 3 year old Australian children. AB - The first 1000 days (conception to 24 months) is when gut microbiota composition and eating patterns are established, and a critical period influencing lifelong health. The aim of this study is to examine the associations between food intakes and microbiota composition at the end of this period. Diet was quantified for 37 well-nourished Australian children aged between 2 to 3 years by using a food frequency questionnaire and 24 hr recalls. Both dairy and plant-based (fruit, vegetables, soy, pulses and nuts) food intakes were associated with distinct microbiota profiles. Dairy intake was positively associated with the Firmicutes:Bacteroidetes ratio, and in particular Erysipelatoclostridium spp., but negatively associated with species richness and diversity. Vegetable intake was positively associated with the relative abundance of the Lachnospira genus, while soy, pulse and nut intake was positively associated with the relative abundance of bacteria related to Bacteroides xylanisolvens. Fruit intake, especially apples and pears, were negatively associated with the relative abundance of bacteria related to Ruminococcus gnavus. In this cohort of young children dairy and plant based food intakes were found to be associated with altered microbiota composition. Further exploration is needed to elucidate the effect of these dietary and microbial differences on host phenotype. PMID- 27694809 TI - Epigenetic inheritance of acquired traits through sperm RNAs and sperm RNA modifications. AB - Once deemed heretical, emerging evidence now supports the notion that the inheritance of acquired characteristics can occur through ancestral exposures or experiences and that certain paternally acquired traits can be 'memorized' in the sperm as epigenetic information. The search for epigenetic factors in mammalian sperm that transmit acquired phenotypes has recently focused on RNAs and, more recently, RNA modifications. Here, we review insights that have been gained from studying sperm RNAs and RNA modifications, and their roles in influencing offspring phenotypes. We discuss the possible mechanisms by which sperm become acquisitive following environmental-somatic-germline interactions, and how they transmit paternally acquired phenotypes by shaping early embryonic development. PMID- 27694813 TI - Characterization of Toxin Genes and Antimicrobial Susceptibility of Staphylococcus aureus Isolates in Fishery Products in Iran. AB - Staphylococcus aureus is one of the most common causes of seafood-borne diseases worldwide, which are attributable to the contamination of food by preformed enterotoxins. In this study, a total of 206 (34.3%) Staphylococcus aureus strains were obtained from 600 fish and shrimp samples and were tested for their antimicrobial susceptibility. We assessed the prevalence of the genes responsible for the staphylococcal enterotoxins (SEA, SEB) and toxic shock syndrome toxin 1 (TSST-1) genes. The results indicated that 34% of aqua food samples were contaminated with S. aureus, and 23.8% of these isolates were mec-A-positive. Sixty-four percent of the strains isolated from contaminated seafood was enterotoxigenic S. aureus, and 28.2% of SEs were MRSA-positive. The most prevalent genotype was characterized by the presence of the sea gene (45.2%), followed by the seb gene (18.5%), and the tst gene encoding TSST-1 was found in eight strains (3.9%). Of the 206 S. aureus isolates, 189 strains (84.9%) were resistant to at least one antibiotic. Given the frequent outbreaks of enterotoxigenic MRSA, it is necessary to make revisions to mandatory programmes to facilitate improved hygiene practices during fishing, aquaculture, processing, and sales to prevent the contamination of fishery products in Iran. PMID- 27694812 TI - A plasma membrane microdomain compartmentalizes ephrin-generated cAMP signals to prune developing retinal axon arbors. AB - The development of neuronal circuits is controlled by guidance molecules that are hypothesized to interact with the cholesterol-enriched domains of the plasma membrane termed lipid rafts. Whether such domains enable local intracellular signalling at the submicrometre scale in developing neurons and are required for shaping the nervous system connectivity in vivo remains controversial. Here, we report a role for lipid rafts in generating domains of local cAMP signalling in axonal growth cones downstream of ephrin-A repulsive guidance cues. Ephrin-A dependent retraction of retinal ganglion cell axons involves cAMP signalling restricted to the vicinity of lipid rafts and is independent of cAMP modulation outside of this microdomain. cAMP modulation near lipid rafts controls the pruning of ectopic axonal branches of retinal ganglion cells in vivo, a process requiring intact ephrin-A signalling. Together, our findings indicate that lipid rafts structure the subcellular organization of intracellular cAMP signalling shaping axonal arbors during the nervous system development. PMID- 27694814 TI - Ultrastable glasses portray similar behaviour to ordinary glasses at high pressure. AB - Pressure experiments provide a unique opportunity to unravel new insights into glass-forming liquids by exploring its effect on the dynamics of viscous liquids and on the evolution of the glass transition temperature. Here we compare the pressure dependence of the onset of devitrification, Ton, between two molecular glasses prepared from the same material but with extremely different ambient pressure kinetic and thermodynamic stabilities. Our data clearly reveal that, while both glasses exhibit different dTon/dP values at low pressures, they evolve towards closer calorimetric devitrification temperature and pressure dependence as pressure increases. We tentatively interpret these results from the different densities of the starting materials at room temperature and pressure. Our data shows that at the probed pressures, the relaxation time of the glass into the supercooled liquid is determined by temperature and pressure similarly to the behaviour of liquids, but using stability-dependent parameters. PMID- 27694815 TI - Correlation of serum hepcidin levels with disease progression in hepatitis B virus-related disease assessed by nanopore film based assay. AB - Chronic hepatitis B virus (HBV) infection often develop into cirrhosis, and both are major risk factors of hepatocellular carcinoma. However, effective approaches for the monitoring of HBV-related disease progress are still in need. Increased iron storage has an important role in HBV-related diseases. Hepcidin is a key regulator of iron homeostasis whose expression changes are often indicative of abnormal iron metabolism. There are few reports of hepcidin levels in patients with HBV infections, and the available results are inconsistent. In this study, using a recently validated nanopore silica film based method, we measured serum hepcidin levels in 46 HBV-related patients and 20 healthy controls. Patients were divided into three groups: chronic hepatitis B without cirrhosis; HBV-related cirrhosis; and HBV-related cirrhosis with hepatocellular carcinoma. Compared to healthy controls, the mean serum hepcidin level was significantly higher in CHB patients without cirrhosis, and in those with hepatocellular carcinoma, but not in those with cirrhosis. Iron-loading, viral infection and liver dysfunction are determined to be the major regulators of hepcidin in these patients. These observations suggest correlations between serum hepcidin and progression of chronic HBV infection, and may shed a new light on the development of biomarkers for HBV-related disease surveillance. PMID- 27694816 TI - Dimerization deficiency of enigmatic retinitis pigmentosa-linked rhodopsin mutants. AB - Retinitis pigmentosa (RP) is a blinding disease often associated with mutations in rhodopsin, a light-sensing G protein-coupled receptor and phospholipid scramblase. Most RP-associated mutations affect rhodopsin's activity or transport to disc membranes. Intriguingly, some mutations produce apparently normal rhodopsins that nevertheless cause disease. Here we show that three such enigmatic mutations-F45L, V209M and F220C-yield fully functional visual pigments that bind the 11-cis retinal chromophore, activate the G protein transducin, traffic to the light-sensitive photoreceptor compartment and scramble phospholipids. However, tests of scramblase activity show that unlike wild-type rhodopsin that functionally reconstitutes into liposomes as dimers or multimers, F45L, V209M and F220C rhodopsins behave as monomers. This result was confirmed in pull-down experiments. Our data suggest that the photoreceptor pathology associated with expression of these enigmatic RP-associated pigments arises from their unexpected inability to dimerize via transmembrane helices 1 and 5. PMID- 27694817 TI - Efficient long-term cryopreservation of pluripotent stem cells at -80 degrees C. AB - Current long term cryopreservation of cell stocks routinely requires the use of liquid nitrogen (LN2), because commonly used cryopreservation media containing cell membrane permeating cryoprotectants are thermally unstable when frozen at higher storage temperatures, e.g. -80 degrees C. This instability leads to ice recrystallization, causing progressive loss of cell viability over time under the storage conditions provided by most laboratory deep freezers. The dependency on LN2 for cell storage significantly increases operational expense and raises issues related to impaired working efficiency and safety. Here we demonstrate that addition of Ficoll 70 to cryoprotectant solutions significantly improves system thermal stability at the working temperature (~-80 degrees C) of laboratory deep freezers. Moreover, a medium comprised of Ficoll 70 and dimethyl sulfoxide (DMSO) in presence or absence of fetal bovine serum (FBS) can provide reliable cryopreservation of various kinds of human and porcine pluripotent stem cells at -80 degrees C for periods that extend up to at least one year, with the post-thaw viability, plating efficiency, and full retention of pluripotent phenotype comparable to that achieved with LN2 storage. These results illustrate the practicability of a promising long-term cryopreservation method that completely eliminates the need for LN2. PMID- 27694819 TI - Pollen-mediated gene flow and seed exchange in small-scale Zambian maize farming, implications for biosafety assessment. AB - Gene flow in agricultural crops is important for risk assessment of genetically modified (GM) crops, particularly in countries with a large informal agricultural sector of subsistence cultivation. We present a pollen flow model for maize (Zea mays), a major staple crop in Africa. We use spatial properties of fields (size, position) in three small-scale maize farming communities in Zambia and estimate rates of cross-fertilisation between fields sown with different maize varieties (e.g. conventional and transgene). As an additional factor contributing to gene flow, we present data on seed saving and sharing among farmers that live in the same communities. Our results show that: i) maize fields were small and located in immediate vicinity of neighboring fields; ii) a majority of farmers saved and shared seed; iii) modeled rates of pollen-mediated gene flow showed extensive mixing of germplasm between fields and farms and iv) as a result, segregation of GM and non-GM varieties is not likely to be an option in these systems. We conclude that the overall genetic composition of maize, in this and similar agricultural contexts, will be strongly influenced both by self-organised ecological factors (pollen flow), and by socially mediated intervention (seed recycling and sharing). PMID- 27694818 TI - Reduced lipolysis response to adipose afferent reflex involved in impaired activation of adrenoceptor-cAMP-PKA-hormone sensitive lipase pathway in obesity. AB - Chemical stimulation of white adipose tissue (WAT) causes adipose afferent reflex (AAR) and sympathetic activation. This study is to investigate the effects of AAR on lipolysis and the mechanisms of attenuated lipolysis response to enhanced AAR in obesity. Obesity was caused by high-fat diet for 12 weeks in rats. AAR was induced by injection of capsaicin into inguinal WAT or electrical stimulation of epididymal WAT afferent nerve. AAR caused sympathetic activation, which was enhanced in obesity rats. AAR increased cAMP levels and PKA activity, promoted hormone sensitive lipase (HSL) and perilipin phosphorylation, and increased lipolysis in WAT, which were attenuated in obesity rats. PKA activity, cAMP, perilipin and beta-adrenoceptor levels were reduced, while HSL was upregulated in adipocytes from obesity rats. In primary adipocytes, isoproterenol increased cAMP levels and PKA activity, promoted HSL and perilipin phosphorylation, and increased lipolysis, which were attenuated in obesity rats. The attenuated effects of isoproterenol in adipocytes from obesity rats were prevented by a cAMP analogue dbcAMP. The results indicate that reduced lipolysis response to enhanced AAR in obesity is attributed to the impaired activation of beta-adrenoceptor-cAMP PKA-HSL pathway. Increased cAMP level in adipocytes rectifies the attenuated lipolysis in obesity. PMID- 27694820 TI - A novel method for preparing microplastic fibers. AB - Microscopic plastic (microplastic, 0.1 um-5 mm) is a widespread pollutant impacting upon aquatic ecosystems across the globe. Environmental sampling has revealed synthetic fibers are prevalent in seawater, sediments and biota. However, microplastic fibers are rarely used in laboratory studies as they are unavailable for purchase and existing preparation techniques have limited application. To facilitate the incorporation of environmentally relevant microplastic fibers into future studies, new methods are required. Here, a novel cryotome protocol has been developed. Nylon, polyethylene terephthalate and polypropylene fibers (10-28 MUm diameter) were aligned, embedded in water-soluble freezing agent, and sectioned (40-100 MUm length) using a cryogenic microtome. Microplastic fibers were prepared to specified lengths (P < 0.05, ANOVA) and proved consistent in size. Fluorescent labelling of Nylon microfibers with Nile Red facilitated imaging. A 24 h feeding experiment confirmed bioavailability of 10 * 40 MUm Nylon fibers to brine shrimp (Artemia sp). This protocol provides a consistent method for preparing standardised fibrous microplastics, with widths similar to those observed in the natural environment, which could ultimately lead to a better understanding of the biological and ecological effects of microplastic debris in the environment.

PMID- 27694823 TI - Coral recovery in the central Maldives archipelago since the last major mass bleaching, in 1998. AB - Increasing frequency and severity of disturbances is causing global degradation of coral reef ecosystems. This study examined temporal changes in live coral cover and coral composition in the central Maldives from 1997 to 2016, encompassing two bleaching events, a tsunami, and an outbreak of Acanthaster planci. We also examined the contemporary size structure for five dominant coral taxa (tabular Acropora, Acropora muricata, Acropora humilis, Pocillopora spp, and massive Porites). Total coral cover increased throughout the study period, with marked increases following the 1998 mass-bleaching. The relative abundance of key genera has changed through time, where Acropora and Pocillopora (which are highly susceptible to bleaching) were under-represented following 1998 mass-bleaching but increased until outbreaks of A. planci in 2015. The contemporary size structure for all coral taxa was dominated by larger colonies with peaked distributions suggesting that recent disturbances had a disproportionate impact on smaller colonies, or that recruitment is currently limited. This may suggest that coral resilience has been compromised by recent disturbances, and further bleaching (expected in 2016) could lead to highly protracted recovery times. We showed that Maldivian reefs recovered following the 1998 mass-bleaching event, but it took up to a decade, and ongoing disturbances may be eroding reef resilience. PMID- 27694822 TI - A sensitive electrochemical sensor for in vitro detection of parathyroid hormone based on a MoS2-graphene composite. AB - This paper reports a biosensor based on a MoS2-graphene (MG) composite that can measure the parathyroid hormone (PTH) concentration in serum samples from patients. The interaction between PTH and MG was analysed via an electrochemical sensing technique. The MG was functionalized using l-cysteine. Following this, PTH could be covalently immobilized on the MG sensing electrode. The properties of MG were evaluated using scanning electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectrometry. Following optimization of immobilized materials-such as MG, PTH, and alkaline phosphatase (ALP)-the performance of the MG sensor was investigated via cyclic voltammetry, to assess its linearity, repeatability, and reproducibility. Electrochemical impedance spectroscopy was performed on graphene oxide (GO) and MG-modified electrodes to confirm the capture of a monoclonal antibody (MAb) targeting PTH. Furthermore, the ALP-PTH-MG sensor exhibits a linear response towards PTH from artificial serum over a range of 1-50 pg mL-1. Moreover, patient sera (n = 30) were evaluated using the ALP-PTH-MG sensor and compared using standard equipment (Roche E 170). The P-value is less than 0.01 when evaluated with a t-test using Welch's correction. This implies that the fabricated sensor can be deployed for medical diagnosis. PMID- 27694824 TI - A Statistical Learning Framework for Materials Science: Application to Elastic Moduli of k-nary Inorganic Polycrystalline Compounds. AB - Materials scientists increasingly employ machine or statistical learning (SL) techniques to accelerate materials discovery and design. Such pursuits benefit from pooling training data across, and thus being able to generalize predictions over, k-nary compounds of diverse chemistries and structures. This work presents a SL framework that addresses challenges in materials science applications, where datasets are diverse but of modest size, and extreme values are often of interest. Our advances include the application of power or Holder means to construct descriptors that generalize over chemistry and crystal structure, and the incorporation of multivariate local regression within a gradient boosting framework. The approach is demonstrated by developing SL models to predict bulk and shear moduli (K and G, respectively) for polycrystalline inorganic compounds, using 1,940 compounds from a growing database of calculated elastic moduli for metals, semiconductors and insulators. The usefulness of the models is illustrated by screening for superhard materials. PMID- 27694825 TI - Tracing ancestor rice of Suriname Maroons back to its African origin. AB - African rice (Oryza glaberrima) and African cultivation practices are said to have influenced emerging colonial plantation economies in the Americas1,2. However, the level of impact of African rice practices is difficult to establish because of limited written or botanical records2,3. Recent findings of O. glaberrima in rice fields of Suriname Maroons bear evidence of the high level of knowledge about rice among African slaves and their descendants, who consecrate it in ancestor rituals4,5. Here we establish the strong similarity, and hence likely origin, of the first extant New World landrace of O. glaberrima to landraces from the Upper Guinean forests in West Africa. We collected African rice from a Maroon market in Paramaribo, Suriname, propagated it, sequenced its genome6 and compared it with genomes of 109 accessions representing O. glaberrima diversity across West Africa. By analysing 1,649,769 single nucleotide polymorphisms (SNPs) in clustering analyses, the Suriname sample appears sister to an Ivory Coast landrace, and shows no evidence of introgression from Asian rice. Whereas the Dutch took most slaves from Ghana, Benin and Central Africa7, the diaries of slave ship captains record the purchase of food for provisions when sailing along the West African Coast8, offering one possible explanation for the patterns of genetic similarity. This study demonstrates the utility of genomics in understanding the largely unwritten histories of crop cultures of diaspora communities. PMID- 27694826 TI - Hydrodynamic role of longitudinal dorsal ridges in a leatherback turtle swimming. AB - Leatherback sea turtles (Dermochelys coriacea) are known to have a superior diving ability and be highly adapted to pelagic swimming. They have five longitudinal ridges on their carapace. Although it was conjectured that these ridges might be an adaptation for flow control, no rigorous study has been performed to understand their hydrodynamic roles. Here we show that these ridges are slightly misaligned to the streamlines around the body to generate streamwise vortices, and suppress or delay flow separation on the carapace, resulting in enhanced hydrodynamic performances during different modes of swimming. Our results suggest that shapes of some morphological features of living creatures, like the longitudinal ridges of the leatherback turtles, need not be streamlined for excellent hydro- or aerodynamic performances, contrary to our common physical intuition. PMID- 27694827 TI - Chemical chaperone TUDCA prevents apoptosis and improves survival during polymicrobial sepsis in mice. AB - Sepsis-induced lymphopenia is a major cause of morbidities in intensive care units and in populations with chronic conditions such as renal failure, diabetes, HIV and alcohol abuse. Currently, other than supportive care and antibiotics, there are no treatments for this condition. We developed an in vitro assay to understand the role of the ER-stress-mediated apoptosis process in lymphocyte death during polymicrobial sepsis, which was reproducible in in vivo mouse models. Modulating ER stress using chemical chaperones significantly reduced the induction of the pro-apoptotic protein Bim both in vitro and in mice. Furthermore, in a 'two-hit' pneumonia model in mice, we have been able to demonstrate that administration of the chemical chaperone TUDCA helped to maintain lymphocyte homeostasis by significantly reducing lymphocyte apoptosis and this correlated with four-fold improvement in survival. Our results demonstrate a novel therapeutic opportunity for treating sepsis-induced lymphopenia in humans. PMID- 27694829 TI - Systemic Inhibition of CREB is Well-tolerated in vivo. AB - cAMP-response element binding protein (CREB) is a nuclear transcription factor activated by multiple extracellular signals including growth factors and hormones. These extracellular cues activate CREB through phosphorylation at Ser133 by various protein serine/threonine kinases. Once phosphorylated, it promotes its association with transcription coactivators CREB-binding protein (CBP) and its paralog p300 to activate CREB-dependent gene transcription. Tumor tissues of different origins have been shown to present overexpression and/or overactivation of CREB, indicating CREB as a potential cancer drug target. We previously identified 666-15 as a potent inhibitor of CREB with efficacious anti cancer activity both in vitro and in vivo. Herein, we investigated the specificity of 666-15 and evaluated its potential in vivo toxicity. We found that 666-15 was fairly selective in inhibiting CREB. 666-15 was also found to be readily bioavailable to achieve pharmacologically relevant concentrations for CREB inhibition. Furthermore, the mice treated with 666-15 showed no evidence of changes in body weight, complete blood count, blood chemistry profile, cardiac contractility and tissue histologies from liver, kidney and heart. For the first time, these results demonstrate that pharmacological inhibition of CREB is well tolerated in vivo and indicate that such inhibitors should be promising cancer therapeutics. PMID- 27694830 TI - Noise reduction facilitated by dosage compensation in gene networks. AB - Genetic noise together with genome duplication and volume changes during cell cycle are significant contributors to cell-to-cell heterogeneity. How can cells buffer the effects of these unavoidable epigenetic and genetic variations on phenotypes that are sensitive to such variations? Here we show that a simple network motif that is essential for network-dosage compensation can reduce the effects of extrinsic noise on the network output. Using natural and synthetic gene networks with and without the network motif, we measure gene network activity in single yeast cells and find that the activity of the compensated network is significantly lower in noise compared with the non-compensated network. A mathematical analysis provides intuitive insights into these results and a novel stochastic model tracking cell-volume and cell-cycle predicts the experimental results. Our work implies that noise is a selectable trait tunable by evolution. PMID- 27694828 TI - Comprehensive functional analysis of the tousled-like kinase 2 frequently amplified in aggressive luminal breast cancers. AB - More aggressive and therapy-resistant oestrogen receptor (ER)-positive breast cancers remain a great clinical challenge. Here our integrative genomic analysis identifies tousled-like kinase 2 (TLK2) as a candidate kinase target frequently amplified in ~10.5% of ER-positive breast tumours. The resulting overexpression of TLK2 is more significant in aggressive and advanced tumours, and correlates with worse clinical outcome regardless of endocrine therapy. Ectopic expression of TLK2 leads to enhanced aggressiveness in breast cancer cells, which may involve the EGFR/SRC/FAK signalling. Conversely, TLK2 inhibition selectively inhibits the growth of TLK2-high breast cancer cells, downregulates ERalpha, BCL2 and SKP2, impairs G1/S cell cycle progression, induces apoptosis and significantly improves progression-free survival in vivo. We identify two potential TLK2 inhibitors that could serve as backbones for future drug development. Together, amplification of the cell cycle kinase TLK2 presents an attractive genomic target for aggressive ER-positive breast cancers. PMID- 27694831 TI - RAB39B gene mutations are not linked to familial Parkinson's disease in China. AB - Recently, RAB39B mutations were reported to be a causative factor in patients with Parkinson's disease (PD). To validate the role of RAB39B in familial PD, a total of 195 subjects consisting of 108 PD families with autosomal-dominant (AD) inheritance and 87 PD families with autosomal-recessive (AR) inheritance in the Chinese Han population from mainland China were included in this study. We did not identify any variants in the coding region or the exon-intron boundaries of the gene by Sanger sequencing method in the DNA samples of 180 patients (100 with AD and 80 with AR). Furthermore, we did not find any variants in the RAB39B gene when Whole-exome sequencing (WES) was applied to DNA samples from 15 patients (8 with AD and 7 with AR) for further genetic analysis. Additionally, when quantitative real-time PCR was used to exclude large rearrangement variants in these patients, we found no dosage mutations in RAB39B gene. Our results suggest that RAB39B mutation is very rare in familial PD and may not be a major cause of familial PD in the Chinese Han Population. PMID- 27694832 TI - Quantifying the dilution of the radiocesium contamination in Fukushima coastal river sediment (2011-2015). AB - Fallout from the Fukushima Dai-ichi nuclear power plant accident resulted in a 3000-km2 radioactive contamination plume. Here, we model the progressive dilution of the radiocesium contamination in 327 sediment samples from two neighboring catchments with different timing of soil decontamination. Overall, we demonstrate that there has been a ~90% decrease of the contribution of upstream contaminated soils to sediment transiting the coastal plains between 2012 (median - M - contribution of 73%, mean absolute deviation - MAD - of 27%) and 2015 (M 9%, MAD 6%). The occurrence of typhoons and the progress of decontamination in different tributaries of the Niida River resulted in temporary increases in local contamination. However, the much lower contribution of upstream contaminated soils to coastal plain sediment in November 2015 demonstrates that the source of the easily erodible, contaminated material has potentially been removed by decontamination, diluted by subsoils, or eroded and transported to the Pacific Ocean.

AB - Molecular electronics originally proposed that small molecules sandwiched between electrodes would accomplish electronic functions and enable ultimate scaling to be reached. However, so far, functional molecular devices have only been demonstrated at low frequency. Here, we demonstrate molecular diodes operating up to 17.8 GHz. Direct current and radio frequency (RF) properties were simultaneously measured on a large array of molecular junctions composed of gold nanocrystal electrodes, ferrocenyl undecanethiol molecules and the tip of an interferometric scanning microwave microscope. The present nanometre-scale molecular diodes offer a current density increase by several orders of magnitude compared with that of micrometre-scale molecular diodes, allowing RF operation. The measured S11 parameters show a diode rectification ratio of 12 dB which is linked to the rectification behaviour of the direct current conductance. From the RF measurements, we extrapolate a cut-off frequency of 520 GHz. A comparison with the silicon RF-Schottky diodes, architecture suggests that the RF-molecular diodes are extremely attractive for scaling and high-frequency operation.

AB - Hematopoietic pre-B cell leukemia transcription factor (PBX)-interacting protein (HPIP) was shown to be crucial during the development and progression of a variety of tumors. However, the role of HPIP in renal cell carcinoma (RCC) is unknown. Here we report that HPIP is upregulated in most RCC patients, positively correlates with tumor size, high Fuhrman grade and preoperative metastasis, and predicts poor clinical outcomes. Mechanistically, we identified casein kinase 1alpha (CK1alpha), a critical regulator of tumorigenesis and metastasis, as a novel HPIP-interacting protein. HPIP facilitates RCC cell growth, migration, invasion and epithelial-mesenchymal transition depending on its interaction with CK1alpha. Activation of mammalian target of rapamycin pathways by HPIP is partly dependent on CK1alpha and is required for HPIP modulation of RCC cell proliferation and migration. HPIP knockdown suppresses renal tumor growth and metastasis in nude mice through CK1alpha. Moreover, expression of CK1alpha is positively correlated with HPIP in RCC samples, and also predicts poor clinical outcome-like expression of HPIP. Taken together, our data demonstrate the critical regulatory role of the HPIP-CK1alpha interaction in RCC, and suggest that HPIP and CK1alpha may be potential targets for RCC therapy.

AB - Dual oxidase 1 (DUOX1) is an oxidant-generating enzyme within the airway epithelium that participates in innate airway host defense and epithelial homeostasis. Recent studies indicate that DUOX1 is suppressed in lung cancers by epigenetic silencing, although the importance of DUOX1 silencing in lung cancer development or progression is unknown. Here we show that loss of DUOX1 expression in a panel of lung cancer cell lines is strongly associated with loss of the epithelial marker E-cadherin. Moreover, RNAi-mediated DUOX1 silencing in lung epithelial cells and the cancer cell line NCI-H292 was found to result in loss of epithelial characteristics/molecular features (altered morphology, reduced barrier function and loss of E-cadherin) and increased mesenchymal features (increased migration, anchorage-independent growth and gain of vimentin/collagen), suggesting a direct contribution of DUOX1 silencing to epithelial-to-mesenchymal transition (EMT), an important feature of metastatic cancer. Conversely, overexpression of DUOX1 in A549 cells was capable of reversing EMT features. DUOX1 silencing in H292 cells also led to enhanced resistance to epidermal growth factor receptor tyrosine kinase inhibitors such as erlotinib, and enhanced levels of cancer stem cell (CSC) markers CD133 and ALDH1. Furthermore, acquired resistance of H292 cells to erlotinib resulted in enhanced EMT and CSC features, as well as loss of DUOX1. Finally, compared with control H292 cells, H292-shDUOX1 cells displayed enhanced invasive features in vitro and in vivo. Collectively, our findings indicate that DUOX1 silencing in lung epithelial cancer cells promotes features of EMT, and may be strongly associated with invasive and metastatic lung cancer.

PMID- 27694836 TI - The Zn-finger domain of MdmX suppresses cancer progression by promoting genome stability in p53-mutant cells. AB - The MDMX (MDM4) oncogene is amplified or overexpressed in a significant percentage of human tumors. MDMX is thought to function as an oncoprotein by binding p53 tumor suppressor protein to inhibit p53-mediated transcription, and by complexing with MDM2 oncoprotein to promote MDM2-mediated degradation of p53. However, down-regulation or loss of functional MDMX has also been observed in a variety of human tumors that are mutated for p53, often correlating with more aggressive cancers and a worse patient prognosis. We have previously reported that endogenous levels of MdmX can suppress proliferation and promote pseudo bipolar mitosis in primary and tumor cells derived from p53-deficient mice, and that MdmX-p53 double deficient mice succumb to spontaneously formed tumors more rapidly than p53-deficient mice. These results suggest that the MdmX oncoprotein may act as a tumor-suppressor in cancers with compromised p53 function. By using orthotopic transplantation and lung colonization assays in mice we now establish a p53-independent anti-oncogenic role for MdmX in tumor progression. We also demonstrate that the roles of MdmX in genome stability and in proliferation are two distinct functions encoded by the separate MdmX protein domains. The central Zn-finger domain suppresses multipolar mitosis and chromosome loss, whereas the carboxy-terminal RING domain suppresses proliferation of p53-deficient cells. Furthermore, we determine that it is the maintenance of genome stability that underlies MdmX role in suppression of tumorigenesis in hyperploid p53 mutant tumors. Our results offer a rationale for the increased metastatic potential of p53 mutant human cancers with aberrant MdmX function and provide a caveat for the application of anti-MdmX treatment of tumors with compromised p53 activity. PMID- 27694839 TI - Investigating enhanced mechanical properties in dual-phase Fe-Ga-Tb alloys. AB - Dual-phase (Fe83Ga17)100-xTbx alloys with 0 <= x <= 1 were synthesized by arc melting and homogenization treatment. The microstructures and the corresponding mechanical properties were systematically investigated. The chemical composition of the body centered cubic matrix is Fe83Ga17. The monoclinic second phase was composed of meltable precipitates with approximate composition Fe57Ga33Tb10. The nano-hardness of matrix and precipitates were 2.55 +/- 0.17 GPa and 6.81 +/- 1.03 GPa, respectively. Both the ultimate tensile strength (UTS) and fracture strain (epsilon) of the alloys were improved by the precipitates for x <= 0.2 alloys, but the strain decreases significantly at higher values of x. As potential structural-functional materials, the best mechanical properties obtained were a UTS of 595 +/- 10 MPa and an epsilon of 3.5 +/- 0.1%, four-fold and seven-fold improvements compared with the un-doped alloy. The mechanism for these anomalous changes of mechanical properties was attributed to the dispersed precipitates and semi-coherent interfaces, which serve as strong obstacles to dislocation motion and reduce the stress concentration at the grain boundaries. A sizeable improvement of magnetostriction induced by the precipitates in the range 0 <= x <= 0.2 was discovered and an optimal value of 150 +/- 5 ppm is found, over three times higher than that of the un-doped alloy. PMID- 27694838 TI - A vector platform for the rapid and efficient engineering of stable complex transgenes. AB - We describe the generation of a set of plasmid vector tools that allow the rapid generation of complex-interacting stable transgenes in immortalized and primary cells. Of particular importance is inclusion of a mechanism to monitor the activation status of regulatory pathways via a reporter cassette (using Gaussia Luciferase), with control of additional transgene expression through doxycycline de-repression. The resulting vectors can be used to assess regulatory pathway activation and are well suited for regulatory pathway crosstalk studies. The system incorporates MultiSite-Gateway cloning for the rapid generation of vectors allowing flexible choice of promoters and transgenes, and Sleeping Beauty transposase technology for efficient incorporation of multiple transgenes in into host cell DNA. The vectors and a library of compatible Gateway Entry clones are available from the non-profit plasmid repository Addgene. PMID- 27694840 TI - Insertion of an Alu element in a lncRNA leads to primate-specific modulation of alternative splicing. AB - Noncoding RNAs, mobile elements, and alternative splicing are all critical for the regulation of gene expression. Here we show that a conserved noncoding RNA acquires a new function due to the insertion of a mobile element. We identified a noncoding RNA, termed 5S-OT, which is transcribed from 5S rDNA loci in eukaryotes including fission yeast and mammals. 5S-OT plays a cis role in regulating the transcription of 5S rRNA in mice and humans. In the anthropoidea suborder of primates, an antisense Alu element has been inserted at the 5S-OT locus. We found that in human cells, 5S-OT regulates alternative splicing of multiple genes in trans via Alu/anti-Alu pairing with target genes and by interacting with the splicing factor U2AF65. This trans effect of 5S-OT in splicing might be exploited in biotechnological applications. PMID- 27694841 TI - Structure of the active form of Dcp1-Dcp2 decapping enzyme bound to m7GDP and its Edc3 activator. AB - Elimination of the 5' cap of eukaryotic mRNAs, known as decapping, is considered to be a crucial, irreversible and highly regulated step required for the rapid degradation of mRNA by Xrn1, the major cytoplasmic 5'-3' exonuclease. Decapping is accomplished by the recruitment of a protein complex formed by the Dcp2 catalytic subunit and its Dcp1 cofactor. However, this complex has a low intrinsic enzymatic activity and requires several accessory proteins such as the Lsm1-7 complex, Pat1, Edc1-Edc2 and/or Edc3 to be fully active. Here we present the crystal structure of the active form of the yeast Kluyveromyces lactis Dcp1 Dcp2 enzyme bound to its product (m7GDP) and its potent activator Edc3. This structure of the Dcp1-Dcp2 complex bound to a cap analog further explains previously published data on substrate binding and provides hints as to the mechanism of Edc3-mediated Dcp2 activation. PMID- 27694842 TI - Structural basis of mRNA-cap recognition by Dcp1-Dcp2. AB - Removal of the 5' cap on mRNA by the decapping enzyme Dcp2 is a critical step in 5'-to-3' mRNA decay. Understanding the structural basis of Dcp2 activity has been a challenge because Dcp2 is dynamic and has weak affinity for the cap substrate. Here we present a 2.6-A-resolution crystal structure of a heterotrimer of fission yeast Dcp2, its essential activator Dcp1, and the human NMD cofactor PNRC2, in complex with a tight-binding cap analog. Cap binding is accompanied by a conformational change in Dcp2, thereby forming a composite nucleotide-binding site comprising conserved residues in the catalytic and regulatory domains. Kinetic analysis of PNRC2 revealed that a conserved short linear motif enhances both substrate affinity and the catalytic step of decapping. These findings explain why Dcp2 requires a conformational change for efficient catalysis and reveals that coactivators promote RNA binding and the catalytic step of decapping, possibly through different conformational states. PMID- 27694843 TI - The Growth Pattern of Tibetan Infants at High Altitudes: a Cohort Study in Rural Tibet region. AB - Studies on growth pattern of Tibetan infants and the difference from other child groups were limited due to its special living environment and unique customs. In this study, 253 Tibetan infants were followed-up from their birth to 12th month in rural Tibet. Five visits were conducted and weight and length were measured at each visit. Mixed model was employed to analyze the growth pattern of Tibetan infants and its comparison to the Han infants. Propensity Scores (PS) technique was adopted to control for the potential confounding factors. The mixed model found that the birth weight/length had a negative impact on the increment of Tibetan infants after birth (weight: beta = -0.6819, P < 0.0001, length: beta = 0.9571, P < 0.0001). The weight increment of Tibetan infants was greater than Han infant with age (betaage*ethnic = 0.0345, P < 0.001), after using PS as a covariant. And another mixed model in which PS was used as a matching factor found similar trend. Compared with Chinese Han infants, Tibetan infants were lower weight and shorter length within one year after birth but they had greater increment of weight, suggesting that Tibetan infants might have a significant catch-up growth within the first year of life. PMID- 27694844 TI - An Adaptive Fisher's Combination Method for Joint Analysis of Multiple Phenotypes in Association Studies. AB - Currently, the analyses of most genome-wide association studies (GWAS) have been performed on a single phenotype. There is increasing evidence showing that pleiotropy is a widespread phenomenon in complex diseases. Therefore, using only one single phenotype may lose statistical power to identify the underlying genetic mechanism. There is an increasing need to develop and apply powerful statistical tests to detect association between multiple phenotypes and a genetic variant. In this paper, we develop an Adaptive Fisher's Combination (AFC) method for joint analysis of multiple phenotypes in association studies. The AFC method combines p-values obtained in standard univariate GWAS by using the optimal number of p-values which is determined by the data. We perform extensive simulations to evaluate the performance of the AFC method and compare the power of our method with the powers of TATES, Tippett's method, Fisher's combination test, MANOVA, MultiPhen, and SUMSCORE. Our simulation studies show that the proposed method has correct type I error rates and is either the most powerful test or comparable with the most powerful test. Finally, we illustrate our proposed methodology by analyzing whole-genome genotyping data from a lung function study. PMID- 27694845 TI - Methyl-CpG binding domain protein acts to regulate the repair of cyclobutane pyrimidine dimers on rice DNA. AB - UVB radiation causes cyclobutane pyrimidine dimers (CPDs) to form on the DNA of living organisms. This study found that overexpression of the silicon absorbance gene Lsi1 reduced the accumulation of CPDs in rice, which profited from the reactivation by photolyase. The transcript abundance of deoxyribodipyrimidine photolyase (Os10g0167600) was generally correlated with the silicon content of the rice, and the up-regulation of Os10g0167600 was found to be highest in the UVB-treated Lsi1-overexpressed (Lsi1-OX) rice. A trans-acting factor, methyl-CpG binding domain protein (OsMeCP), was found to interact with the cis-element of Os10g0167600. The nucleic location of OsMeCP effectively enabled the transcriptional regulation. Compared with the WT, the level of OsMeCP was lower in the Lsi1-OX rice but higher in the Lsi1-RNAi line. Rice cultured in a high silicate-concentration solution also exhibited less OsMeCP abundance. Overexpression of OsMeCP led to lower Os10g0167600 transcript levels and a higher CPD content than in the WT, but the reverse was true in the OsMeCP-RNAi line. These findings indicate that OsMeCP acts as a negative regulator of silicon, and can mediate the repression of the transcription from Os10g0167600, which inhibits the photoreactivation of the photolyase involved in the repair of CPDs.

AB - Electron spins in gate-defined quantum dots provide a promising platform for quantum computation. In particular, spin-based quantum computing in gallium arsenide takes advantage of the high quality of semiconducting materials, reliability in fabricating arrays of quantum dots and accurate qubit operations. However, the effective magnetic noise arising from the hyperfine interaction with uncontrolled nuclear spins in the host lattice constitutes a major source of decoherence. Low-frequency nuclear noise, responsible for fast (10 ns) inhomogeneous dephasing, can be removed by echo techniques. High-frequency nuclear noise, recently studied via echo revivals, occurs in narrow-frequency bands related to differences in Larmor precession of the three isotopes 69Ga, 71Ga and 75As (refs 15,16,17). Here, we show that both low- and high-frequency nuclear noise can be filtered by appropriate dynamical decoupling sequences, resulting in a substantial enhancement of spin qubit coherence times. Using nuclear notch filtering, we demonstrate a spin coherence time (T2) of 0.87 ms, five orders of magnitude longer than typical exchange gate times, and exceeding the longest coherence times reported to date in Si/SiGe gate-defined quantum dots. PMID- 27694846 TI - EIN2-dependent regulation of acetylation of histone H3K14 and non-canonical histone H3K23 in ethylene signalling. AB - Ethylene gas is essential for many developmental processes and stress responses in plants. EIN2 plays a key role in ethylene signalling but its function remains enigmatic. Here, we show that ethylene specifically elevates acetylation of histone H3K14 and the non-canonical acetylation of H3K23 in etiolated seedlings. The up-regulation of these two histone marks positively correlates with ethylene regulated transcription activation, and the elevation requires EIN2. Both EIN2 and EIN3 interact with a SANT domain protein named EIN2 nuclear associated protein 1 (ENAP1), overexpression of which results in elevation of histone acetylation and enhanced ethylene-inducible gene expression in an EIN2-dependent manner. On the basis of these findings we propose a model where, in the presence of ethylene, the EIN2 C terminus contributes to downstream signalling via the elevation of acetylation at H3K14 and H3K23. ENAP1 may potentially mediate ethylene-induced histone acetylation via its interactions with EIN2 C terminus. PMID- 27694849 TI - Nanoscale topographical control of capillary assembly of nanoparticles. AB - Predetermined and selective placement of nanoparticles onto large-area substrates with nanometre-scale precision is essential to harness the unique properties of nanoparticle assemblies, in particular for functional optical and electro-optical nanodevices. Unfortunately, such high spatial organization is currently beyond the reach of top-down nanofabrication techniques alone. Here, we demonstrate that topographic features comprising lithographed funnelled traps and auxiliary sidewalls on a solid substrate can deterministically direct the capillary assembly of Au nanorods to attain simultaneous control of position, orientation and interparticle distance at the nanometre level. We report up to 100% assembly yield over centimetre-scale substrates. We achieve this by optimizing the three sequential stages of capillary nanoparticle assembly: insertion of nanorods into the traps, resilience against the receding suspension front and drying of the residual solvent. Finally, using electron energy-loss spectroscopy we characterize the spectral response and near-field properties of spatially programmable Au nanorod dimers, highlighting the opportunities for precise tunability of the plasmonic modes in larger assemblies. PMID- 27694850 TI - Dynamic peptide libraries for the discovery of supramolecular nanomaterials. AB - Sequence-specific polymers, such as oligonucleotides and peptides, can be used as building blocks for functional supramolecular nanomaterials. The design and selection of suitable self-assembling sequences is, however, challenging because of the vast combinatorial space available. Here we report a methodology that allows the peptide sequence space to be searched for self-assembling structures. In this approach, unprotected homo- and heterodipeptides (including aromatic, aliphatic, polar and charged amino acids) are subjected to continuous enzymatic condensation, hydrolysis and sequence exchange to create a dynamic combinatorial peptide library. The free-energy change associated with the assembly process itself gives rise to selective amplification of self-assembling candidates. By changing the environmental conditions during the selection process, different sequences and consequent nanoscale morphologies are selected. PMID- 27694851 TI - Site-specific identification of heparan and chondroitin sulfate glycosaminoglycans in hybrid proteoglycans. AB - Heparan sulfate (HS) and chondroitin sulfate (CS) are complex polysaccharides that regulate important biological pathways in virtually all metazoan organisms. The polysaccharides often display opposite effects on cell functions with HS and CS structural motifs presenting unique binding sites for specific ligands. Still, the mechanisms by which glycan biosynthesis generates complex HS and CS polysaccharides required for the regulation of mammalian physiology remain elusive. Here we present a glycoproteomic approach that identifies and differentiates between HS and CS attachment sites and provides identity to the core proteins. Glycopeptides were prepared from perlecan, a complex proteoglycan known to be substituted with both HS and CS chains, further digested with heparinase or chondroitinase ABC to reduce the HS and CS chain lengths respectively, and thereafter analyzed by nLC-MS/MS. This protocol enabled the identification of three consensus HS sites and one hybrid site, carrying either a HS or a CS chain. Inspection of the amino acid sequence at the hybrid attachment locus indicates that certain peptide motifs may encode for the chain type selection process. This analytical approach will become useful when addressing fundamental questions in basic biology specifically in elucidating the functional roles of site-specific glycosylations of proteoglycans. PMID- 27694852 TI - Pulled microcapillary tube resonators with electrical readout for mass sensing applications. AB - This paper reports a microfabrication-free approach to make hollow channel mass sensors by pulling a glass capillary and suspending it on top of a machined jig. A part of the pulled section makes simple contact with an actuation node and a quartz tuning fork (QTF) which acts as a sensing node. The two nodes define a pulled micro capillary tube resonator (PMUTR) simply supported at two contacts. While a piezo actuator beneath the actuation node excites the PMUTR, the QTF senses the resonance frequency of the PMUTR. The proposed concept was validated by electrical and optical measurements of resonant spectra of PMUTR. Then, different liquid samples including water, ethanol, glycerol, and their binary mixtures were introduced into the PMUTR and the resonance frequency of the PMUTR was measured as a function of liquid density. Density responsivity of -3,088 Hz-g 1 cm3 obtained is comparable to those of microfabricated hollow resonators. With a micro droplet generation chip configured in series with the PMUTR, size distribution of oil droplets suspended in water was successfully measured with the radius resolution of 31 nm at the average droplet radius, 28.47 MUm. Overall, typical off-the-shelf parts simply constitute a resonant mass sensing system along with a convenient electrical readout. PMID- 27694853 TI - Improved affinity at the cost of decreased specificity: a recurring theme in PDZ peptide interactions. AB - The E6 protein from human papillomavirus (HPV) plays an important role during productive infection and is a potential drug target. We have previously designed a high affinity bivalent protein binder for the E6 protein, a fusion between a helix from the E6 associated protein and PDZO9, an engineered variant (L391F/K392M) of the second PDZ domain from synapse associated protein 97 (SAP97 PDZ2). How the substitutions improve the affinity of SAP97 PDZ2 for HPV E6 is not clear and it is not known to what extent they affect the specificity for cellular targets. Here, we explore the specificity of wild type SAP97 PDZ2 and PDZO9 through proteomic peptide phage display. In addition, we employ a double mutant cycle of SAP97 PDZ2 in which the binding kinetics for nine identified potential cellular peptide ligands are measured and compared with those for the C-terminal E6 peptide. The results demonstrate that PDZO9 has an increased affinity for all peptides, but at the cost of specificity. Furthermore, there is a peptide dependent coupling free energy between the side chains at positions 391 and 392. This corroborates our previous allosteric model for PDZ domains, involving sampling of intramolecular energetic pathways. PMID- 27694854 TI - Subcellular and in-vivo Nano-Endoscopy. AB - Analysis of individual cells at the subcellular level is important for understanding diseases and accelerating drug discovery. Nanoscale endoscopes allow minimally invasive probing of individual cell interiors. Several such instruments have been presented previously, but they are either too complex to fabricate or require sophisticated external detectors because of low signal collection efficiency. Here we present a nanoendoscope that can locally excite fluorescence in labelled cell organelles and collect the emitted signal for spectral analysis. Finite Difference Time Domain (FDTD) simulations have shown that with an optimized nanoendoscope taper profile, the light emission and collection was localized within ~100 nm. This allows signal detection to be used for nano-photonic sensing of the proximity of fluorophores. Upon insertion into the individual organelles of living cells, the nanoendoscope was fabricated and resultant fluorescent signals collected. This included the signal collection from the nucleus of Acridine orange labelled human fibroblast cells, the nucleus of Hoechst stained live liver cells and the mitochondria of MitoTracker Red labelled MDA-MB-231 cells. The endoscope was also inserted into a live organism, the yellow fluorescent protein producing nematode Caenorhabditis elegans, and a fluorescent signal was collected. To our knowledge this is the first demonstration of in vivo, local fluorescence signal collection on the sub organelle level. PMID- 27694856 TI - Revisit to three-dimensional percolation theory: Accurate analysis for highly stretchable conductive composite materials. AB - A percolation theory based on variation of conductive filler fraction has been widely used to explain the behavior of conductive composite materials under both small and large deformation conditions. However, it typically fails in properly analyzing the materials under the large deformation since the assumption may not be valid in such a case. Therefore, we proposed a new three-dimensional percolation theory by considering three key factors: nonlinear elasticity, precisely measured strain-dependent Poisson's ratio, and strain-dependent percolation threshold. Digital image correlation (DIC) method was used to determine actual Poisson's ratios at various strain levels, which were used to accurately estimate variation of conductive filler volume fraction under deformation. We also adopted strain-dependent percolation threshold caused by the filler re-location with deformation. When three key factors were considered, electrical performance change was accurately analyzed for composite materials with both isotropic and anisotropic mechanical properties. PMID- 27694855 TI - Analysis of microRNA and Gene Expression Profiles in Multiple Sclerosis: Integrating Interaction Data to Uncover Regulatory Mechanisms. AB - MicroRNAs (miRNAs) have been reported to contribute to the pathophysiology of multiple sclerosis (MS), an inflammatory disorder of the central nervous system. Here, we propose a new consensus-based strategy to analyse and integrate miRNA and gene expression data in MS as well as other publically available data to gain a deeper understanding of the role of miRNAs in MS and to overcome the challenges posed by studies with limited patient sample sizes. We processed and analysed microarray datasets, and compared the expression of genes and miRNAs in the blood of MS patients and controls. We then used our consensus and integration approach to construct two molecular networks dysregulated in MS: a miRNA- and a gene-based network. We identified 18 differentially expressed (DE) miRNAs and 128 DE genes that may contribute to the regulatory alterations behind MS. The miRNAs were linked to immunological and neurological pathways, and we exposed let-7b-5p and miR-345-5p as promising blood-derived disease biomarkers in MS. The results suggest that DE miRNAs are more informative than DE genes in uncovering pathways potentially involved in MS. Our findings provide novel insights into the regulatory mechanisms and networks underlying MS. PMID- 27694857 TI - Editorial: Statins for Inflammatory Bowel Disease: Expanding the Scope of Prevention. AB - In addition to cholesterol depletion, statins also significantly decrease systemic inflammation as measured by C-reactive protein. In this issue of American Journal of Gastroenterology, Ungaro et al. present their results on the associations between statin prescriptions and risk of Crohn's disease (CD) and ulcerative colitis (UC). Using a national medical claims and pharmacy database created by Symphony Health Solutions LLC (SHA), they show that any use of statin is protective against diagnosis of CD and UC. The protective effect against CD appears strongest among older populations (>60 years old). These findings offer intriguing insights into inflammatory pathways that could be modulated by cholesterol lowering drugs. In addition, if replicated in other cohorts, these results provide further rationale for investigating the use of statins in broader preventive efforts, including healthy patients at risk of developing inflammatory bowel disease.

AB - During their lifetime, about 10% of the population will develop a peptic ulcer. Despite major advancements in the approach to peptic ulcer bleeding over the last 10-20 years including newer endoscopic hemostatic techniques and the advent of proton pump inhibitors (PPIs), upper gastrointestinal bleeding due to peptic ulcers results in substantial morbidity, mortality, and cost. Both oral and intravenous PPIs have proven to be effective in preventing recurrent bleeding from peptic ulcers. However, the dosing and administration of PPIs have been a source of ongoing debate, specifically in relation to cost. In this issue of the Journal, Lu et al. perform cost analysis demonstrating that costs from bleeding peptic ulcers are influenced more by efficient triage and discharge of patients than the nuances of variations in administration of intravenous PPI's.

AB - To evaluate the relative importance of photosynthetic versus morphological adaptations of submersed macrophytes to low light intensity in lakes, rapid light curves (RLCs), morphological parameters, relative growth rate (RGR), clonal reproduction and abundance of two submersed macrophytes (Potamogeton maackianus and Vallisneria natans) were examined under 2.8%, 7.1%, 17.1% and 39.5% ambient light in a field and outdoor experimental study. The plants increased their initial slope of RLCs (alpha) and decreased their minimum saturating irradiance (Ek) and maximum relative electron transport rate (ETRm) of RLCs under low light stress, but V. natans was more sensitive in RLCs than P. maackianus. Accordingly, the RGR, plant height and abundance of P. maackianus were higher in the high light regimes (shallow water) but lower in the low light regimes than those of V. natans. At the 2.8% ambient light, V. natans produced ramets and thus fulfilled its population expansion, in contrast to P. maackianus. The results revealed that P. maackianus as a canopy-former mainly elongated its shoot length towards the water surface to compensate for the low light conditions, however, it became limited in severe low light stress conditions. V. natans as a rosette adapted to low light stress mainly through photosynthetic adjustments and superior to severely low light than shoot elongation.

PMID- 27694879 TI - Ageing increases reliance on sensorimotor prediction through structural and functional differences in frontostriatal circuits. AB - The control of voluntary movement changes markedly with age. A critical component of motor control is the integration of sensory information with predictions of the consequences of action, arising from internal models of movement. This leads to sensorimotor attenuation-a reduction in the perceived intensity of sensations from self-generated compared with external actions. Here we show that sensorimotor attenuation occurs in 98% of adults in a population-based cohort (n=325; 18-88 years; the Cambridge Centre for Ageing and Neuroscience). Importantly, attenuation increases with age, in proportion to reduced sensory sensitivity. This effect is associated with differences in the structure and functional connectivity of the pre-supplementary motor area (pre-SMA), assessed with magnetic resonance imaging. The results suggest that ageing alters the balance between the sensorium and predictive models, mediated by the pre-SMA and its connectivity in frontostriatal circuits. This shift may contribute to the motor and cognitive changes observed with age. PMID- 27694882 TI - The trafficking of bacterial type rhodopsins into the Chlamydomonas eyespot and flagella is IFT mediated. AB - The bacterial type rhodopsins are present in all the three domains of life. In contrast to the animal type rhodopsin that performs mainly sensory functions in higher eukaryotes, the bacterial type rhodopsin could function as ion channel, pumps and as sensory proteins. The functioning of rhodopsin in higher eukaryotes requires the transport of rhodopsin from its site of synthesis to the ciliated outer segment of the photoreceptive cells. However, the trafficking of bacterial type rhodopsin from its site of synthesis to the position of action is not characterized. Here we present the first report for the existence of an IFT interactome mediated trafficking of the bacterial type rhodopsins into eyespot and flagella of the Chlamydomonas. We show that there is a light-dependent, dynamic localization of rhodopsins between flagella and eyespot of Chlamydomonas. The involvement of IFT components in the rhodopsin trafficking was elucidated by the use of conditional IFT mutants. We found that rhodopsin can be co immunoprecipitated with the components of IFT machinery and with other protein components required for the IFT-cargo complex formation. These findings show that light-regulated localization of rhodopsin is not restricted to animals thereby suggesting that rhodopsin trafficking is an IFT dependent ancient process.

AB - Piezos are mechanically activated ion channels that function as sensors of touch and pressure in various cell types. However, the precise mechanism and structures mediating mechanical activation and subsequent inactivation have not yet been identified. Here we use magnetic nanoparticles as localized transducers of mechanical force in combination with pressure-clamp electrophysiology to identify mechanically sensitive domains important for activation and inactivation.

AB - Chromosome alignment is required for accurate chromosome segregation. Chromosome misalignment can result in genomic instability and tumorigenesis. Here, we show that NF-kappaB activating protein (NKAP) is critical for chromosome alignment through anchoring CENP-E to kinetochores. NKAP knockdown causes chromosome misalignment and prometaphase arrest in human cells. NKAP dynamically localizes to kinetochores, and is required for CENP-E kinetochore localization. NKAP is SUMOylated predominantly in mitosis and the SUMOylation is needed for NKAP to bind CENP-E. A SUMOylation-deficient mutant of NKAP cannot support the localization of CENP-E on kinetochores or proper chromosome alignment. Moreover, Bub3 recruits NKAP to stabilize the binding of CENP-E to BubR1 at kinetochores. Importantly, loss of NKAP expression causes aneuploidy in cultured cells, and is observed in human soft tissue sarcomas. These findings indicate that NKAP is a novel and key regulator of mitosis, and its dysregulation might contribute to tumorigenesis by causing chromosomal instability.

AB - The interaction between Earth's magnetic field and the solar wind results in the formation of a collisionless bow shock 60,000-100,000 km upstream of our planet, as long as the solar wind fast magnetosonic Mach (hereafter Mach) number exceeds unity. Here, we present one of those extremely rare instances, when the solar wind Mach number reached steady values <1 for several hours on 17 January 2013. Simultaneous measurements by more than ten spacecraft in the near-Earth environment reveal the evanescence of the bow shock, the sunward motion of the magnetopause and the extremely rapid and intense loss of electrons in the outer radiation belt. This study allows us to directly observe the state of the inner magnetosphere, including the radiation belts during a type of solar wind magnetosphere coupling which is unusual for planets in our solar system but may be common for close-in extrasolar planets. PMID- 27694885 TI - Emerging pathogenic links between microbiota and the gut-lung axis. AB - The microbiota is vital for the development of the immune system and homeostasis. Changes in microbial composition and function, termed dysbiosis, in the respiratory tract and the gut have recently been linked to alterations in immune responses and to disease development in the lungs. In this Opinion article, we review the microbial species that are usually found in healthy gastrointestinal and respiratory tracts, their dysbiosis in disease and interactions with the gut lung axis. Although the gut-lung axis is only beginning to be understood, emerging evidence indicates that there is potential for manipulation of the gut microbiota in the treatment of lung diseases. PMID- 27694889 TI - Landscape mapping at sub-Antarctic South Georgia provides a protocol for underpinning large-scale marine protected areas. AB - Global biodiversity is in decline, with the marine environment experiencing significant and increasing anthropogenic pressures. In response marine protected areas (MPAs) have increasingly been adopted as the flagship approach to marine conservation, many covering enormous areas. At present, however, the lack of biological sampling makes prioritising which regions of the ocean to protect, especially over large spatial scales, particularly problematic. Here we present an interdisciplinary approach to marine landscape mapping at the sub-Antarctic island of South Georgia as an effective protocol for underpinning large-scale (105-106 km2) MPA designations. We have developed a new high-resolution (100 m) digital elevation model (DEM) of the region and integrated this DEM with bathymetry-derived parameters, modelled oceanographic data, and satellite primary productivity data. These interdisciplinary datasets were used to apply an objective statistical approach to hierarchically partition and map the benthic environment into physical habitats types. We assess the potential application of physical habitat classifications as proxies for biological structuring and the application of the landscape mapping for informing on marine spatial planning. PMID- 27694888 TI - Statistical and Ontological Analysis of Adverse Events Associated with Monovalent and Combination Vaccines against Hepatitis A and B Diseases. AB - Vaccinations often induce various adverse events (AEs), and sometimes serious AEs (SAEs). While many vaccines are used in combination, the effects of vaccine vaccine interactions (VVIs) on vaccine AEs are rarely studied. In this study, AE profiles induced by hepatitis A vaccine (Havrix), hepatitis B vaccine (Engerix B), and hepatitis A and B combination vaccine (Twinrix) were studied using the VAERS data. From May 2001 to January 2015, VAERS recorded 941, 3,885, and 1,624 AE case reports where patients aged at least 18 years old were vaccinated with only Havrix, Engerix-B, and Twinrix, respectively. Using these data, our statistical analysis identified 46, 69, and 82 AEs significantly associated with Havrix, Engerix-B, and Twinrix, respectively. Based on the Ontology of Adverse Events (OAE) hierarchical classification, these AEs were enriched in the AEs related to behavioral and neurological conditions, immune system, and investigation results. Twenty-nine AEs were classified as SAEs and mainly related to immune conditions. Using a logistic regression model accompanied with MCMC sampling, 13 AEs (e.g., hepatosplenomegaly) were identified to result from VVI synergistic effects. Classifications of these 13 AEs using OAE and MedDRA hierarchies confirmed the advantages of the OAE-based method over MedDRA in AE term hierarchical analysis. PMID- 27694890 TI - An interaction between Scribble and the NADPH oxidase complex controls M1 macrophage polarization and function. AB - The polarity protein Scribble (SCRIB) regulates apical-basal polarity, directional migration and tumour suppression in Drosophila and mammals. Here we report that SCRIB is an important regulator of myeloid cell functions including bacterial infection and inflammation. SCRIB interacts directly with the NADPH oxidase (NOX) complex in a PSD95/Dlg/ZO-1 (PDZ)-domain-dependent manner and is required for NOX-induced reactive oxygen species (ROS) generation in culture and in vivo. On bacterial infection, SCRIB localized to phagosomes in a leucine-rich repeat-dependent manner and promoted ROS production within phagosomes to kill bacteria. Unexpectedly, SCRIB loss promoted M1 macrophage polarization and inflammation. Thus, SCRIB uncouples ROS-dependent bacterial killing activity from M1 polarization and inflammatory functions of macrophages. Modulating the SCRIB NOX pathway can therefore identify ways to manage infection and inflammation with implications for chronic inflammatory diseases, sepsis and cancer. PMID- 27694891 TI - Statistical Analysis of Main and Interaction Effects on Cu(II) and Cr(VI) Decontamination by Nitrogen-Doped Magnetic Graphene Oxide. AB - A nitrogen-doped magnetic graphene oxide (NMGO) was synthesized and applied as an adsorbent to remove Cu(II) and Cr(VI) ions from aqueous solutions. The individual and combined effects of various factors (A: pH, B: temperature, C: initial concentration of metal ions, D: CaCl2, and E: humic acid [HA]) on the adsorption were analyzed by a 25-1 fractional factorial design (FFD). The results from this study indicated that the NMGO had higher adsorption capacities for Cu(II) ions than for Cr(VI) ions under most conditions, and the five selected variables affected the two adsorption processes to different extents. A, AC, and C were the very important factors and interactions for Cu(II) adsorption. For Cr(VI) adsorption, A, B, C, AB, and BC were found to be very important influencing variables. The solution pH (A) was the most important influencing factor for removal of both the ions. The main effects of A-E on the removal of Cu(II) were positive. For Cr(VI) adsorption, the main effects of A and D were negative, while B, C, and E were observed to have positive effects. The maximum adsorption capacities for Cu(II) and Cr(VI) ions over NMGO were 146.365 and 72.978 mg/g, respectively, under optimal process conditions. PMID- 27694892 TI - ZEB1 induces LOXL2-mediated collagen stabilization and deposition in the extracellular matrix to drive lung cancer invasion and metastasis. AB - Lung cancer is the leading cause of cancer-related deaths, primarily due to distant metastatic disease. Metastatic lung cancer cells can undergo an epithelial-to-mesenchymal transition (EMT) regulated by various transcription factors, including a double-negative feedback loop between the microRNA-200 (miR 200) family and ZEB1, but the precise mechanisms by which ZEB1-dependent EMT promotes malignancy remain largely undefined. Although the cell-intrinsic effects of EMT are important for tumor progression, the reciprocal dynamic crosstalk between mesenchymal cancer cells and the extracellular matrix (ECM) is equally critical in regulating invasion and metastasis. Investigating the collaborative effect of EMT and ECM in the metastatic process reveals increased collagen deposition in metastatic tumor tissues as a direct consequence of amplified collagen gene expression in ZEB1-activated mesenchymal lung cancer cells. In addition, collagen fibers in metastatic lung tumors exhibit greater linearity and organization as a result of collagen crosslinking by the lysyl oxidase (LOX) family of enzymes. Expression of the LOX and LOXL2 isoforms is directly regulated by miR-200 and ZEB1, respectively, and their upregulation in metastatic tumors and mesenchymal cell lines is coordinated to that of collagen. Functionally, LOXL2, as opposed to LOX, is the principal isoform that crosslinks and stabilizes insoluble collagen deposition in tumor tissues. In turn, focal adhesion formation and FAK/SRC signaling is activated in mesenchymal tumor cells by crosslinked collagen in the ECM. Our study is the first to validate direct regulation of LOX and LOXL2 by the miR-200/ZEB1 axis, defines a novel mechanism driving tumor metastasis, delineates collagen as a prognostic marker, and identifies LOXL2 as a potential therapeutic target against tumor progression. PMID- 27694893 TI - Transducin (beta)-like 1 X-linked receptor 1 promotes gastric cancer progression via the ERK1/2 pathway. AB - Gastric cancer (GC) is one of the most common types of cancer worldwide, and it involves extensive local tumour invasion, metastasis and poor prognosis. Understanding the mechanisms regulating the progression of GC is necessary for the development of effective therapeutic strategies. Transducin (beta)-like 1 X linked receptor 1 (TBL1XR1) is an important regulator controlling gene activation and repression, which has been thought to be involved in tumorigenesis. However, the role of TBL1XR1 in human GC remains largely unknown. Here, we find that TBL1XR1 is aberrantly expressed in human GC tissues, and TBL1XR1 levels are highly correlated with local tumour invasion, late tumor, lymph node, metastasis (TNM) stage and poor prognosis. Knockdown of TBL1XR1 by shRNA inhibits GC cell proliferation, migration, invasion, epithelial-mesenchymal transition (EMT) in vitro, as well as tumorigenesis and peritoneal metastasis in vivo, whereas overexpression of TBL1XR1 produces the opposite effects. These effects are mediated by activation of the ERK1/2 signalling pathway, and inhibition of this pathway with a specific ERK1/2 inhibitor (U0126) significantly impairs the tumour promoting effects induced by TBL1XR1. Moreover, TBL1XR1 mediated ERK1/2 activation is dependent on the beta-catenin/MMP7/EGFR signalling pathway. In conclusion, TBL1XR1 contributes to GC tumorigenesis and progression through the activation of the beta-catenin/MMP7/EGFR/ERK signalling pathway and may act as a new therapeutic target for GC. PMID- 27694894 TI - NPM-ALK phosphorylates WASp Y102 and contributes to oncogenesis of anaplastic large cell lymphoma. AB - Mechanisms by which NPM-ALK signaling regulates cell migration, invasion and contributes to the oncogenesis of anaplastic large cell lymphoma (ALCL) are not completely understood. In an attempt to identify novel actin signaling pathways regulated by NPM-ALK, a comprehensive phosphoproteome analysis of ALCL cell lines was performed in the presence or absence of NPM-ALK activity. Numerous phosphoproteins involved in actin dynamics including Wiskott-Aldrich syndrome protein (WASp) were regulated by NPM-ALK. Network analysis revealed that WASp is a central component of the NPM-ALK-dependent actin signaling pathway. Here we show that NPM-ALK phosphorylates WASp at its known activation site (Y290) as well as at a novel residue (Y102). Phosphorylation of WASp at Y102 negatively regulates its interaction with Wiskott-Aldrich interacting protein and decreases its protein stability. Phosphorylation of WASp at Y102 enhances anchorage independent growth and tumor growth in an in vivo xenograft model and enhances invasive properties of ALCL. We show that knock-down of WASp or expression of Y102F mutant of WASp decreases colony formation and in vivo tumor growth. Our results show that WASp is a novel substrate of ALK and has a critical role in regulating invasiveness and oncogenesis of ALCL. PMID- 27694896 TI - An in vivo screening system to identify tumorigenic genes. AB - Screening for oncogenes has mostly been performed by in vitro transformation assays. However, some oncogenes might not exhibit their transforming activities in vitro unless putative essential factors from in vivo microenvironments are adequately supplied. Here, we have developed an in vivo screening system that evaluates the tumorigenicity of target genes. This system uses a retroviral high efficiency gene transfer technique, a large collection of human cDNA clones corresponding to ~70% of human genes and a luciferase-expressing immortalized mouse mammary epithelial cell line (NMuMG-luc). From 845 genes that were highly expressed in human breast cancer cell lines, we focused on 205 genes encoding membrane proteins and/or kinases as that had the greater possibility of being oncogenes or drug targets. The 205 genes were divided into five subgroups, each containing 34-43 genes, and then introduced them into NMuMG-luc cells. These cells were subcutaneously injected into nude mice and monitored for tumor development by in vivo imaging. Tumors were observed in three subgroups. Using DNA microarray analyses and individual tumorigenic assays, we found that three genes, ADORA2B, PRKACB and LPAR3, were tumorigenic. ADORA2B and LPAR3 encode G protein-coupled receptors and PRKACB encodes a protein kinase A catalytic subunit. Cells overexpressing ADORA2B, LPAR3 or PRKACB did not show transforming phenotypes in vitro, suggesting that transformation by these genes requires in vivo microenvironments. In addition, several clinical data sets, including one for breast cancer, showed that the expression of these genes correlated with lower overall survival rate. PMID- 27694895 TI - Identification of a cancer stem cell-specific function for the histone deacetylases, HDAC1 and HDAC7, in breast and ovarian cancer. AB - Tumours are comprised of a highly heterogeneous population of cells, of which only a small subset of stem-like cells possess the ability to regenerate tumours in vivo. These cancer stem cells (CSCs) represent a significant clinical challenge as they are resistant to conventional cancer therapies and play essential roles in metastasis and tumour relapse. Despite this realization and great interest in CSCs, it has been difficult to develop CSC-targeted treatments due to our limited understanding of CSC biology. Here, we present evidence that specific histone deacetylases (HDACs) play essential roles in the CSC phenotype. Utilizing a novel CSC model, we discovered that the HDACs, HDAC1 and HDAC7, are specifically over-expressed in CSCs when compared to non-stem-tumour-cells (nsTCs). Furthermore, we determine that HDAC1 and HDAC7 are necessary to maintain CSCs, and that over-expression of HDAC7 is sufficient to augment the CSC phenotype. We also demonstrate that clinically available HDAC inhibitors (HDACi) targeting HDAC1 and HDAC7 can be used to preferentially target CSCs. These results provide actionable insights that can be rapidly translated into CSC specific therapies. PMID- 27694897 TI - Systematic and functional characterization of novel androgen receptor variants arising from alternative splicing in the ligand-binding domain. AB - The presence of intact ligand-binding domain (LBD) ensures the strict androgen dependent regulation of androgen receptor (AR): binding of androgen induces structural reorganization of LBD resulting in release of AR from HSP90, suppression of nuclear export which otherwise dominates over import and nuclear translocation of AR as a transcription factor. Thus, loss or defects of the LBD abolish constraint from un-liganded LBD as exemplified by constitutively active AR variants (AR-Vs), which are associated with emerging resistance mechanism to anti-AR therapy in castration-resistant prostate cancer (mCRPC). Recent analysis of the AR splicing landscapes revealed mCRPC harboring multiple AR-Vs with diverse patterns of inclusion/exclusion of exons (exons 4-8) corresponding to LBD to produce namely exon-skipping variants. In silico construction for these AR-Vs revealed four novel AR-Vs having unique features: Exclusion of specified exons introduces a frameshift in variants v5es, v6es and v7es. ARv56es maintains the reading frame resulting in the inclusion of the C-terminal half of the LBD. We systematically characterized these AR-Vs regarding their subcellular localization, affinity for HSP90 and transactivation capability. Notably, ARv5es was free from HSP90, exclusively nuclear, and constitutively active similarly as previously reported for v567es. In contrast, v6es and v7es were similar in that they are cytoplasmic, transcriptionally inactive and bind HSP90, ARv56es was present in both nucleus and cytoplasm, does not bind HSP90 and is transcriptionally inactive. Converting these transcriptionally inactive AR-Vs into active forms, we identified the two separate elements that allosterically suppress otherwise constitutively active AR-Vs; one in exon 5 for v6es and v7es and the other in exon 8 for v56es. Our findings identify a novel constitutively active AR-V, ARv5es and establish a method to predict potential activities of AR Vs carrying impaired LBD. PMID- 27694899 TI - APOBEC3A associates with human papillomavirus genome integration in oropharyngeal cancers. AB - The prevalence of human papillomavirus (HPV)-related oropharyngeal cancers has been increasing in developed countries. We recently demonstrated that members of the apolipoprotein B mRNA-editing catalytic polypeptide 3 (APOBEC3, A3) family, which are antiviral factors, can induce hypermutation of HPV DNA in vitro. In the present study, we found numerous C-to-T and G-to-A hypermutations in the HPV16 genome in oropharyngeal cancer (OPC) biopsy samples using differential DNA denaturation PCR and next-generation sequencing. A3s were more abundantly expressed in HPV16-positive OPCs than in HPV-negative, as assessed using immunohistochemistry and reverse transcription quantitative PCR. In addition, interferons upregulated A3s in an HPV16-positive OPC cell line. Furthermore, quantitative PCR analysis of HPV DNA suggests that APOBEC3A (A3A) expression is strongly correlated with the integration of HPV DNA. These results suggest that HPV16 infection may upregulate A3A expression, thereby increasing the chance of viral DNA integration. The role of A3A in HPV-induced carcinogenesis is discussed. PMID- 27694898 TI - Prefoldin 1 promotes EMT and lung cancer progression by suppressing cyclin A expression. AB - Prefoldin (PFDN) is a co-chaperone protein that is primarily known for its classic cytoplasmic functions in the folding of actin and tubulin monomers during cytoskeletal assembly. Here, we report a marked increase in prefoldin subunit 1 (PFDN1) levels during the transforming growth factor (TGF)-beta1-mediated epithelial-mesenchymal transition (EMT) and in human lung tumor tissues. Interestingly, the nuclear localization of PFDN1 was also detected. These observations suggest that PFDN1 may be essential for important novel functions. Overexpression of PFDN1 induced EMT and cell invasion. In sharp contrast, knockdown of PFDN1 generated the opposite effects. Overexpression of PFDN1 was also found to induce lung tumor growth and metastasis. Further experiments showed that PFDN1 overexpression inhibits the expression of cyclin A. PFDN1 suppressed cyclin A expression by directly interacting with the cyclin A promoter at the transcriptional start site. Strikingly, cyclin A overexpression abolished the above PFDN1-mediated effects on the behavior of lung cancer cells, whereas cyclin A knockdown alone induced EMT and increased cell migration and invasion ability. This study reveals that the TGF-beta1/PFDN1/cyclin A axis is essential for EMT induction and metastasis of lung cancer cells. PMID- 27694900 TI - Lysine-specific demethylase KDM3A regulates ovarian cancer stemness and chemoresistance. AB - Ovarian cancer is the leading cause of death among all gynecological malignancies due to the development of acquired chemoresistance and disease relapse. Although the role of cancer stem cells (CSCs), a subset of tumor cells with the self renewal and differentiation capabilities, in therapeutic resistance is beginning to be better understood, the significance of epigenetic regulatory mechanisms responsible for integrating the stemness with drug resistance remain poorly understood. Here we identified that lysine demethylase KDM3A as a critical regulator of ovarian cancer stemness and cisplatin resistance by inducing the expressions of pluripotent molecules Sox2 and Nanog and anti-apoptotic B-cell lymphoma 2 (Bcl-2), respectively. In addition, KDM3A induces ovarian cancer growth while antagonizing cellular senescence by repressing the expression of cyclin-dependent kinase inhibitor, p21Waf1/Cip1. The underlying mechanism of the noted biological processes include KDM3A-mediated stimulation of Sox2 expression, and demethylating p53 protein and consequently, modulating its target genes such as Bcl-2 and p21Waf1/Cip1 expression. Consistently, KDM3A depletion inhibited the growth of subcutaneously implanted cisplatin-resistant human ovarian cancer cells in athymic nude mice. Moreover, KDM3A is abundantly expressed and positively correlated with Sox2 expression in human ovarian cancer tissues. In brief, our findings reveal a novel mechanism by which KDM3A promotes ovarian CSCs, proliferation and chemoresistance and thus, highlights the significance of KDM3A as a novel therapeutic target for resistant ovarian cancer. PMID- 27694901 TI - MYC selects against reduced BCL2A1/A1 protein expression during B cell lymphomagenesis. AB - Rearrangements of MYC or ABL proto-oncogenes lead to deregulated expression of key-regulators of cell cycle and cell survival, thereby constituting important drivers of blood cancer. Members of the BCL-2 family of apoptosis regulators contribute to oncogenic transformation downstream of these oncogenes, but the role of anti-apoptotic BCL2A1/A1 in transformation and drug resistance caused by deregulation of these oncogenes remains enigmatic. Here we analyzed the role of A1 in MYC as well as ABL kinase-driven blood cancer in mice, employing in vivo RNAi. We report that overexpression of either oncogene leads to a significant increase in A1 protein levels in otherwise A1-negative B cell progenitors, indicating a key role downstream of these oncogenes to secure survival during transformation. Knockdown of A1 by RNAi, however, did not impact on tumor latency in v-Abl-driven pre-B-ALL. In contrast, A1 knockdown in premalignant EMU-MYC mice caused a significant reduction of transgenic pre-B cells without impacting on tumor latency as the emerging lymphomas escaped silencing of A1 expression. These findings identify A1 as a MYC target that can be induced prematurely during B cell development to aid expansion of otherwise cell-death-prone MYC transgenic pre-B cells. Hence, A1 should be considered as a putative drug target in MYC driven blood cancer. PMID- 27694902 TI - Functional redundancy between Apc and Apc2 regulates tissue homeostasis and prevents tumorigenesis in murine mammary epithelium. AB - Aberrant Wnt signaling within breast cancer is associated with poor prognosis, but regulation of this pathway in breast tissue remains poorly understood and the consequences of immediate or long-term dysregulation remain elusive. The exact contribution of the Wnt-regulating proteins adenomatous polyposis coli (APC) and APC2 in the pathogenesis of human breast cancer are ill-defined, but our analysis of publically available array data sets indicates that tumors with concomitant low expression of both proteins occurs more frequently in the 'triple negative' phenotype, which is a subtype of breast cancer with particularly poor prognosis. We have used mouse transgenics to delete Apc and/or Apc2 from mouse mammary epithelium to elucidate the significance of these proteins in mammary homeostasis and delineate their influences on Wnt signaling and tumorigenesis. Loss of either protein alone failed to affect Wnt signaling levels or tissue homeostasis. Strikingly, concomitant loss led to local disruption of beta-catenin status, disruption in epithelial integrity, cohesion and polarity, increased cell division and a distinctive form of ductal hyperplasia with 'squamoid' ghost cell nodules in young animals. Upon aging, the development of Wnt activated mammary carcinomas with squamous differentiation was accompanied by a significantly reduced survival. This novel Wnt-driven mammary tumor model highlights the importance of functional redundancies existing between the Apc proteins both in normal homeostasis and in tumorigenesis. PMID- 27694904 TI - Unsupervised vector-based classification of single-molecule charge transport data. AB - The stochastic nature of single-molecule charge transport measurements requires collection of large data sets to capture the full complexity of a molecular system. Data analysis is then guided by certain expectations, for example, a plateau feature in the tunnelling current distance trace, and the molecular conductance extracted from suitable histogram analysis. However, differences in molecular conformation or electrode contact geometry, the number of molecules in the junction or dynamic effects may lead to very different molecular signatures. Since their manifestation is a priori unknown, an unsupervised classification algorithm, making no prior assumptions regarding the data is clearly desirable. Here we present such an approach based on multivariate pattern analysis and apply it to simulated and experimental single-molecule charge transport data. We demonstrate how different event shapes are clearly separated using this algorithm and how statistics about different event classes can be extracted, when conventional methods of analysis fail. PMID- 27694905 TI - In Situ Growth of Highly Adhesive Surface Layer on Titanium Foil as Durable Counter Electrodes for Efficient Dye-sensitized Solar Cells. AB - Counter electrodes (CEs) of dye-sensitized solar cells (DSCs) are usually fabricated by depositing catalytic materials on substrates. The poor adhesion of the catalytic material to the substrate often results in the exfoliation of catalytic materials, and then the deterioration of cell performance or even the failure of DSCs. In this study, a highly adhesive surface layer is in situ grown on the titanium foil via a facile process and applied as CEs for DSCs. The DSCs applying such CEs demonstrate decent power conversion efficiencies, 6.26% and 4.37% for rigid and flexible devices, respectively. The adhesion of the surface layer to the metal substrate is so strong that the photovoltaic performance of the devices is well retained even after the CEs are bended for 20 cycles and torn twice with adhesive tape. The results reported here indicate that the in situ growth of highly adhesive surface layers on metal substrate is a promising way to prepare durable CEs for efficient DSCs. PMID- 27694903 TI - Cip2a promotes cell cycle progression in triple-negative breast cancer cells by regulating the expression and nuclear export of p27Kip1. AB - Triple-negative breast cancer (TNBC) is very aggressive and currently has no specific therapeutic targets; as a consequence, TNBC exhibits poor clinical outcome. In this study, we showed that cancerous inhibitor of protein phosphatase 2A (Cip2a) represents a promising target in TNBC because Cip2a was highly expressed in TNBC cells and tumor tissues, and its expression showed an inverse correlation with overall survival in patients with TNBC. We found that inhibition of Cip2a in TNBC cells induced cell cycle arrest at the G2/M phase, inhibited cell proliferation and delayed tumor growth in the xenograft model. Moreover, Cip2a markedly decreased the expression and nuclear localization of p27Kip1 and this is critical for the ability of Cip2a to promote TNBC progression. Mechanistically, our studies showed that Cip2a promoted p27Kip1 phosphoration at Ser10 via inhibiting Akt-associated PP2A activity, which seems to relocalize p27Kip1 to the cytoplasm in TNBC cells. On the other hand, Cip2a also recruited c myc to mediate the transcriptional inhibition of p27Kip1. Notably, we observed negative correlation between Cip2a and p27Kip1 expression in TNBC specimens. In addition, our data showed that Cip2a depletion could sensitize TNBC to PARP inhibition. Collectively, these data suggested that Cip2a effectively promotes TNBC cell cycle progression and tumor growth via regulation of PP2A/c-myc/p27Kip1 signaling, which could serve as a potential therapeutic target for TNBC patients. PMID- 27694906 TI - CRISPR/Cas9 Targets Chicken Embryonic Somatic Cells In Vitro and In Vivo and generates Phenotypic Abnormalities. AB - Chickens are an invaluable model for studying human diseases, physiology and especially development, but have lagged in genetic applications. With the advent of Programmable Engineered Nucleases, genetic manipulation has become efficient, specific and rapid. Here, we show that the CRISPR/Cas9 system can precisely edit the chicken genome. We generated HIRA, TYRP1, DICER, MBD3, EZH2, and 6 other gene knockouts in two chicken cell lines using the CRISPR/Cas9 system, with no off target effects detected. We also showed that very large deletions (>75 kb) could be achieved. We also achieved targeted modification by homology-directed repair (HDR), producing MEN2A and MEN2B mutations of the RET gene. We also targeted DGCR8 in neural cells of the chicken embryo by in vivo electroporation. After FACS isolation of transfected cells, we observed appropriate sequence changes in DGCR8. Wholemount and frozen section antibody labelling showed reduction of DGCR8 levels in transfected cells. In addition, there was reduced expression levels of DGCR8-associated genes DROSHA, YPEL1 and NGN2. We also observed morphological differences in neural tissue and cardiac-related tissues of transfected embryos. These findings demonstrate that precisely targeted genetic manipulation of the genome using the CRISPR/Cas9 system can be extended to the highly adaptable in vivo chicken embryo model. PMID- 27694907 TI - Physcion, a naturally occurring anthraquinone derivative, induces apoptosis and autophagy in human nasopharyngeal carcinoma. AB - AIM: Physcion is a major bioactive ingredient in the traditional Chinese medicine Radix et Rhizoma Rhei, which has an anthraquinone chemical structure and exhibits a variety of pharmacological activities including laxative, hepatoprotective, anti-inflammatory, anti-microbial and anti-proliferative effects. In this study we investigated the effect of physcion on human nasopharyngeal carcinoma in vitro and in vivo, as well as the mechanisms underlying the anti-tumor action. METHODS: The nasopharyngeal carcinoma cell line CNE2 was treated with physcion, and cell viability was detected using MTT and colony formation assays. Flow cytometry was used to assess the cell cycle arrest, mitochondrial membrane potential loss, apoptosis, autophagy and intracellular ROS generation. Apoptotic cell death was also confirmed by a TUNEL assay. The expression of target or marker molecules was determined using Western blotting. The activity of caspase-3, 8, and 9 was detected with an ELISA kit. A xenograft murine model was used to evaluate the in vivo anti-tumor action of physcion, the mice were administered physcion (10, 20 mg.kg-1.d-1, ip) for 30 d. RESULTS: Treatment with physcion (5, 10, and 20 MUmol/L) dose-dependently suppressed the cell viability and colony formation in CNE2 cells. Physcion (10 and 20 MUmol/L) dose-dependently blocked cell cycle progression at G1 phase and induced both caspase-dependent apoptosis and autophagy in CNE2 cells. Furthermore, physcion treatment induced excessive ROS generation in CNE2 cells, and subsequently disrupted the miR-27a/ZBTB10 axis, resulting in repression of the transcription factor Sp1 that was involved in physcion-induced apoptosis and autophagy. Moreover, physcion-induced autophagy acted as a pro-apoptotic factor, and possibly contributed to physcion-induced apoptosis. In the xenograft murine model, administration of physcion dose dependently suppressed the tumor growth without affecting the body weight. Furthermore, the anti-tumor effects of physcion were correlated with downregulation of Sp1 and suppression of miR-27a in the tumor tissues. CONCLUSION: Physcion induces apoptosis and autophagy in human nasopharyngeal carcinoma by targeting Sp1, which was mediated by ROS/miR-27a/ZBTB10 signaling. The results suggest that physcion is a promising candidate for the treatment of human nasopharyngeal carcinoma.

AB - Considering the complicated pathogenesis of Alzheimer's disease (AD), multi targets have become a focus in the discovery of drugs for treatment of this disease. In the current work, we established a multi-target strategy for discovering active reagents capable of suppressing both Abeta level and Tau hyperphosphorylation from natural products, and found that the ethanol extract of Thamnolia vermicularis (THA) was able to improve learning ability in APP/PS1 transgenic mice by inhibiting both Abeta levels and Tau hyperphosphorylation. SH SY5Y and CHO-APP/BACE1 cells and primary astrocytes were used in cell-based assays. APP/PS1 transgenic mice [B6C3-Tg(APPswe, PS1dE9)] were administered THA (300 mg.kg-1.d-1, ig) for 100 d. After the administration was completed, the learning ability of the mice was detected using a Morris water maze (MWM) assay; immunofluorescence staining, Congo red staining and Thioflavine S staining were used to detect the senile plaques in the brains of the mice. ELISA was used to evaluate Abeta and sAPPbeta contents, and Western blotting and RT-PCR were used to investigate the relevant signaling pathway regulation in response to THA treatment. In SH-SY5Y cells, THAlpha (1, 10, 20 MUg/mL) significantly stimulated PI3K/AKT/mTOR and AMPK/raptor/mTOR signaling-mediated autophagy in the promotion of Abeta clearance as both a PI3K inhibitor and an AMPK indirect activator, and restrained Abeta production as a suppressor against PERK/eIF2alpha-mediated BACE1 expression. Additionally, THA functioned as a GSK3beta inhibitor with an IC50 of 1.32+/-0.85 MUg/mL, repressing Tau hyperphosphorylation. Similar effects on Abeta accumulation and Tau hyperphosphorylation were observed in APP/PS1 transgenic mice treated with THA. Furthermore, administration of THA effectively improved the learning ability of APP/PS1 transgenic mice, and markedly reduced the number of senile plaques in their hippocampus and cortex. The results highlight the potential of the natural product THA for the treatment of AD. PMID- 27694909 TI - Inhibitory effects of hesperetin on Nav1.5 channels stably expressed in HEK 293 cells and on the voltage-gated cardiac sodium current in human atrial myocytes. AB - AIM: Voltage-gated sodium channels composed of a pore-forming alpha subunit and auxiliary beta subunits are responsible for the upstroke of the action potential in cardiac myocytes. The pore-forming subunit of the cardiac sodium channel Nav1.5, which is encoded by SCN5A, is the main ion channel that conducts the voltage-gated cardiac sodium current (INa) in cardiac cells. The current study sought to investigate the inhibitory effects of hesperetin on human cardiac Nav1.5 channels stably expressed in human embryonic kidney 293 (HEK 293) cells and on the voltage-gated cardiac sodium current (INa) in human atrial myocytes. METHODS: The effects of hesperetin on human cardiac Nav1.5 channels expressed in HEK 293 cells and on cardiac Na+ currents in human atrial myocytes were examined through whole-cell patch-clamp techniques. RESULTS: Nav1.5 currents were potently and reversibly suppressed in a concentration- and voltage-dependent manner by hesperetin, which exhibited an IC50 of 62.99 MUmol/L. Hesperetin significantly and negatively shifted the voltage-dependent activation and inactivation curves. Hesperetin also markedly decelerated Nav1.5 current inactivation and slowed the recovery from Nav1.5 channel inactivation. The hesperetin-dependent blockage of Nav1.5 currents was frequency-dependent. Hesperetin also potently and reversibly inhibited Na+ current (INa) in human atrial myocytes, consistently with its effects on Nav1.5 currents in HEK 293 cells. CONCLUSION: Hesperetin is a potent inhibitor of INa in human atrial myocytes and Nav1.5 channels expressed in human embryonic kidney 293 cells. Hesperetin probably functions by blocking the open state and the inactivated state of these channels. PMID- 27694910 TI - Polymorphisms of the KCNQ1 gene are associated with the therapeutic responses of sulfonylureas in Chinese patients with type 2 diabetes. AB - KCNQ1 channel is a member of the voltage-gated potassium channel KQT-like subfamily. The KCNQ1 gene has recently been identified as a susceptibility locus for type 2 diabetes mellitus (T2DM). In the present study, we examined the effects of KCNQ1 variants on the therapeutic response to modified-release gliclazide (gliclazide MR) treatment in Chinese patients newly diagnosed with T2DM. A total of 100 newly diagnosed T2DM patients without a history of any anti diabetic medications were treated with gliclazide MR for 16 weeks, but 91 patients completed the entire study. The anthropometric parameters were determined at baseline and at the final visit, while clinical laboratory tests were performed at baseline and on weeks 2, 4, 6, 12, 16. Two SNPs, rs2237892 and rs2237895, in the region of the KCNQ1 gene were genotyped in all the participants. All calculations and statistical analyses were conducted using SPSS. The rs2237892 TT homozygotes exhibited significantly higher 2-h glucose levels at baseline (P<0.05) and a lower cumulative attainment rate of the target 2-h glucose level (Plog-rank=0.020) than the C allele carriers. Patients with greater numbers of rs2237892 T alleles exhibited larger augmentations (Delta) in the 2-h glucose levels (P=0.027); and patients with the rs2237892 TT genotype exhibited a higher Delta homeostasis model assessment of beta-cell function (HOMA beta) than CC and CT genotype carriers (P=0.021 and P=0.043, respectively). Moreover, the rs2237895 C allele was associated with a greater decrement in Delta glycated hemoglobin (HbA1c) (P=0.024); and patients with the CC genotype exhibited greater variance than those with the AA and AC genotypes (P=0.005 and 0.021, respectively). Compared with the C allele, the odds ratio for treatment success among carriers of the rs2237892 T allele was 2.533 (P=0.007); and the rs2237895 C allele was associated with a 2.360-fold decrease in HbA1c compared with the A allele (P=0.009). KCNQ1 polymorphisms are associated with gliclazide MR efficacy in Chinese patients with type 2 diabetes. PMID- 27694911 TI - Massively parallel single-nucleotide mutagenesis using reversibly terminated inosine. AB - Large-scale mutagenesis of target DNA sequences allows researchers to comprehensively assess the effects of single-nucleotide changes. Here we demonstrate the construction of a systematic allelic series (SAS) using massively parallel single-nucleotide mutagenesis with reversibly terminated deoxyinosine triphosphates (rtITP). We created a mutational library containing every possible single-nucleotide mutation surrounding the active site of the TEM-1 beta lactamase gene. When combined with high-throughput functional assays, SAS mutational libraries can expedite the functional assessment of genetic variation. PMID- 27694912 TI - A bacterial genetic selection system for ubiquitylation cascade discovery. AB - About one-third of the eukaryotic proteome undergoes ubiquitylation, but the enzymatic cascades leading to substrate modification are largely unknown. We present a genetic selection tool that utilizes Escherichia coli, which lack deubiquitylases, to identify interactions along ubiquitylation cascades. Coexpression of split antibiotic resistance protein tethered to ubiquitin and ubiquitylation target together with a functional ubiquitylation apparatus results in a covalent assembly of the resistance protein, giving rise to bacterial growth on selective media. We applied the selection system to uncover an E3 ligase from the pathogenic bacteria EHEC and to identify the epsin ENTH domain as an ultraweak ubiquitin-binding domain. The latter was complemented with a structure function analysis of the ENTH-ubiquitin interface. We also constructed and screened a yeast fusion library, discovering Sem1 as a novel ubiquitylation substrate of Rsp5 E3 ligase. Collectively, our selection system provides a robust high-throughput approach for genetic studies of ubiquitylation cascades and for small-molecule modulator screening. PMID- 27694914 TI - Prediction of postoperative liver regeneration from clinical information using a data-led mathematical model. AB - Although the capacity of the liver to recover its size after resection has enabled extensive liver resection, post-hepatectomy liver failure remains one of the most lethal complications of liver resection. Therefore, it is clinically important to discover reliable predictive factors after resection. In this study, we established a novel mathematical framework which described post-hepatectomy liver regeneration in each patient by incorporating quantitative clinical data. Using the model fitting to the liver volumes in series of computed tomography of 123 patients, we estimated liver regeneration rates. From the estimation, we found patients were divided into two groups: i) patients restored the liver to its original size (Group 1, n = 99); and ii) patients experienced a significant reduction in size (Group 2, n = 24). From discriminant analysis in 103 patients with full clinical variables, the prognosis of patients in terms of liver recovery was successfully predicted in 85-90% of patients. We further validated the accuracy of our model prediction using a validation cohort (prediction = 84 87%, n = 39). Our interdisciplinary approach provides qualitative and quantitative insights into the dynamics of liver regeneration. A key strength is to provide better prediction in patients who had been judged as acceptable for resection by current pragmatic criteria. PMID- 27694915 TI - Integration and exchange of split dCas9 domains for transcriptional controls in mammalian cells. AB - Programmable and precise regulation of dCas9 functions in response to multiple molecular signals by using synthetic gene circuits will expand the application of the CRISPR-Cas technology. However, the application of CRISPR-Cas therapeutic circuits is still challenging due to the restrictive cargo size of existing viral delivery vehicles. Here, we construct logic AND circuits by integrating multiple split dCas9 domains, which is useful to reduce the size of synthetic circuits. In addition, we engineer sensory switches by exchanging split dCas9 domains, allowing differential regulations on one gene, or activating two different genes in response to cell-type specific microRNAs. Therefore, we provide a valuable split-dCas9 toolkit to engineer complex transcription controls, which may inspire new biomedical applications. PMID- 27694913 TI - Crosstalk between autophagy and inflammatory signalling pathways: balancing defence and homeostasis. AB - Autophagy has broad functions in immunity, ranging from cell-autonomous defence to coordination of complex multicellular immune responses. The successful resolution of infection and avoidance of autoimmunity necessitates efficient and timely communication between autophagy and pathways that sense the immune environment. The recent literature indicates that a variety of immune mediators induce or repress autophagy. It is also becoming increasingly clear that immune signalling cascades are subject to regulation by autophagy, and that a return to homeostasis following a robust immune response is critically dependent on this pathway. Importantly, examples of non-canonical forms of autophagy in mediating immunity are pervasive. In this article, the progress in elucidating mechanisms of crosstalk between autophagy and inflammatory signalling cascades is reviewed. Improved mechanistic understanding of the autophagy machinery offers hope for treating infectious and inflammatory diseases. PMID- 27694916 TI - Electrochemical aptasensor for lung cancer-related protein detection in crude blood plasma samples. AB - The development of an aptamer-based electrochemical sensor for lung cancer detection is presented in this work. A highly specific DNA-aptamer, LC-18, selected to postoperative lung cancer tissues was immobilized onto a gold microelectrode and electrochemical measurements were performed in a solution containing the redox marker ferrocyanide/ferricyanide. The aptamer protein targets were harvested from blood plasma of lung cancer patients by using streptavidin paramagnetic beads and square wave voltammetry of the samples was performed at various concentrations. In order to enhance the sensitivity of the aptasensor, silica-coated iron oxide magnetic beads grafted with hydrophobic C8 and C4 alkyl groups were used in a sandwich detection approach. Addition of hydrophobic beads increased the detection limit by 100 times. The detection limit of the LC-18 aptasensor was enhanced by the beads to 0.023 ng/mL. The formation of the aptamer - protein - bead sandwich on the electrode surface was visualized by electron microcopy. As a result, the electrochemical aptasensor was able to detect cancer-related targets in crude blood plasma of lung cancer patients. PMID- 27694918 TI - GDGT distribution in a stratified lake and implications for the application of TEX86 in paleoenvironmental reconstructions. AB - We investigated the relationship between distributions of GDGTs, GDGT-based proxies and environmental factors in a stratified lake in northwestern Norway. More than 90% of isoGDGTs were produced at the bottom of the oxycline, indicating a predominance of ammonia-oxidizing Group I.1a of Thaumarchaeota, supported by high crenarchaeol/caldarchaeol ratios. Dissolved oxygen content, rather than temperature, exercised a primary control on TEX86 values. In spite of low BIT value in surface sediment, the reconstructed lake surface temperature was "cold" biased. MBT values in streams and lake surface water were significantly smaller than those in the catchment soil, suggesting in situ production of brGDGTs in streams. A rapid transition of MBT vs. temperature/pH relationships occurring at the bottom of oxycline indicated the differential production of various brGDGTs with D.O. and depths. Only within the oxycline were CBT-based pH values close to in situ pH. Our results confirm earlier studies calling for caution in applying TEX86 as a surface temperature proxy, or MBT and/or CBT for reconstructing pH, in anoxic or euxinic lakes, estuaries and ocean basins. We propose that caldarchaeol/crenarchaeol ratio, an indicator of contributions from methanogenic archaea, together with the BIT and TEX86 proxies, can help reconstruct past levels of stratification. PMID- 27694917 TI - Soybean GmDREBL Increases Lipid Content in Seeds of Transgenic Arabidopsis. AB - A DREB-type transcription factor gene GmDREBL has been characterized for its functions in oil accumulation in seeds. The gene is specifically expressed in soybean seeds. The GmDREBL is localized in nucleus and has transcriptional activation ability. Overexpression of GmDREBL increased the fatty acid content in the seeds of transgenic Arabidopsis plants. GmDREBL can bind to the promoter region of WRI1 to activate its expression. Several other genes in the fatty acid biosynthesis pathway were also enhanced in the GmDREBL-transgenic plants. The GmDREBL can be up-regulated by GmABI3 and GmABI5. Additionally, overexpression of GmDREBL significantly promoted seed size in transgenic plants compared to that of WT plants. Expression of the DREBL is at higher level on the average in cultivated soybeans than that in wild soybeans. The promoter of the DREBL may have been subjected to selection during soybean domestication. Our results demonstrate that GmDREBL participates in the regulation of fatty acid accumulation by controlling the expression of WRI1 and its downstream genes, and manipulation of the gene may increase the oil contents in soybean plants. Our study provides novel insights into the function of DREB-type transcription factors in oil accumulation in addition to their roles in stress response. PMID- 27694920 TI - Neural Activities Underlying the Feedback Express Salience Prediction Errors for Appetitive and Aversive Stimuli. AB - Feedback information is essential for us to adapt appropriately to the environment. The feedback-related negativity (FRN), a frontocentral negative deflection after the delivery of feedback, has been found to be larger for outcomes that are worse than expected, and it reflects a reward prediction error derived from the midbrain dopaminergic projections to the anterior cingulate cortex (ACC), as stated in reinforcement learning theory. In contrast, the prediction of response-outcome (PRO) model claims that the neural activity in the mediofrontal cortex (mPFC), especially the ACC, is sensitive to the violation of expectancy, irrespective of the valence of feedback. Additionally, increasing evidence has demonstrated significant activities in the striatum, anterior insula and occipital lobe for unexpected outcomes independently of their valence. Thus, the neural mechanism of the feedback remains under dispute. Here, we investigated the feedback with monetary reward and electrical pain shock in one task via functional magnetic resonance imaging. The results revealed significant prediction-error-related activities in the bilateral fusiform gyrus, right middle frontal gyrus and left cingulate gyrus for both money and pain. This implies that some regions underlying the feedback may signal a salience prediction error rather than a reward prediction error. PMID- 27694919 TI - Phycocyanin Inhibits Tumorigenic Potential of Pancreatic Cancer Cells: Role of Apoptosis and Autophagy. AB - Pancreatic adenocarcinoma (PDA) is one of the most lethal human malignancies, and unresponsive to current chemotherapies. Here we investigate the therapeutic potential of phycocyanin as an anti-PDA agent in vivo and in vitro. Phycocyanin, a natural product purified from Spirulina, effectively inhibits the pancreatic cancer cell proliferation in vitro and xenograft tumor growth in vivo. Phycocyanin induces G2/M cell cycle arrest, apoptotic and autophagic cell death in PANC-1 cells. Inhibition of autophagy by targeting Beclin 1 using siRNA significantly suppresses cell growth inhibition and death induced by phycocyanin, whereas inhibition of both autophagy and apoptosis rescues phycocyanin-mediated cell death. Mechanistically, cell death induced by phycocyanin is the result of cross-talk among the MAPK, Akt/mTOR/p70S6K and NF-kappaB pathways. Phycocyanin is able to induce apoptosis of PANC-1 cell by activating p38 and JNK signaling pathways while inhibiting Erk pathway. On the other hand, phycocyanin promotes autophagic cell death by inhibiting PI3/Akt/mTOR signaling pathways. Furthermore, phycocyanin promotes the activation and nuclear translocation of NF-kappaB, which plays an important role in balancing phycocyanin-mediated apoptosis and autosis. In conclusion, our studies demonstrate that phycocyanin exerts anti-pancreatic cancer activity by inducing apoptotic and autophagic cell death, thereby identifying phycocyanin as a promising anti-pancreatic cancer agent. PMID- 27694922 TI - Electrosprayed Multi-Core Alginate Microcapsules as Novel Self-Healing Containers. AB - Alginate microcapsules containing epoxy resin were developed through electrospraying method and embedded into epoxy matrix to produce a capsule-based self-healing composite system. These formaldehyde free alginate/epoxy microcapsules were characterized via light microscope, field emission scanning electron microscope, fourier transform infrared spectroscopy and thermogravimetric analysis. Results showed that epoxy resin was successfully encapsulated within alginate matrix to form porous (multi-core) microcapsules with pore size ranged from 5-100 MUm. The microcapsules had an average size of 320 +/- 20 MUm with decomposition temperature at 220 degrees C. The loading capacity of these capsules was estimated to be 79%. Under in situ healing test, impact specimens showed healing efficiency as high as 86% and the ability to heal up to 3 times due to the multi-core capsule structure and the high impact energy test that triggered the released of epoxy especially in the second and third healings. TDCB specimens showed one-time healing only with the highest healing efficiency of 76%. The single healing event was attributed by the constant crack propagation rate of TDCB fracture test. For the first time, a cost effective, environmentally benign and sustainable capsule-based self-healing system with multiple healing capabilities and high healing performance was developed. PMID- 27694921 TI - Tea polyphenols inhibit the activation of NF-kappaB and the secretion of cytokines and matrix metalloproteinases by macrophages stimulated with Fusobacterium nucleatum. AB - Fusobacterium nucleatum has been associated with both periodontal disease and inflammatory bowel disease. This Gram-negative bacterium possesses a high inflammatory potential that may contribute to the disease process. We hypothesized that green and black tea polyphenols attenuate the inflammatory response of monocytes/macrophages mediated by F. nucleatum. We first showed that the tea extracts, EGCG and theaflavins reduce the NF-kappaB activation induced by F. nucleatum in monocytes. Since NF-kappaB is a key regulator of genes coding for inflammatory mediators, we tested the effects of tea polyphenols on secretion of IL-1beta, IL-6, TNF-alpha, and CXCL8 by macrophages. A pre-treatment of macrophages with the tea extracts, EGCG, or theaflavins prior to a stimulation with F. nucleatum significantly inhibited the secretion of all four cytokines and reduced the secretion of MMP-3 and MMP-9, two tissue destructive enzymes. TREM-1 expressed by macrophages is a cell-surface receptor involved in the propagation of the inflammatory response to bacterial challenges. Interestingly, tea polyphenols inhibited the secretion/shedding of soluble TREM-1 induced by a stimulation of macrophages with F. nucleatum. The anti-inflammatory properties of tea polyphenols identified in the present study suggested that they may be promising agents for the prevention and/or treatment of periodontal disease and inflammatory bowel disease.

PMID- 27694924 TI - Impact of combinatorial dysfunctions of Tet2 and Ezh2 on the epigenome in the pathogenesis of myelodysplastic syndrome. AB - Somatic inactivating mutations in epigenetic regulators are frequently found in combination in myelodysplastic syndrome (MDS). However, the mechanisms by which combinatory mutations in epigenetic regulators promote the development of MDS remain unknown. Here we performed epigenomic profiling of hematopoietic progenitors in MDS mice hypomorphic for Tet2 following the loss of the polycomb group gene Ezh2 (Tet2KD/KDEzh2Delta/Delta). Aberrant DNA methylation propagated in a sequential manner from a Tet2-insufficient state to advanced MDS with deletion of Ezh2. Hyper-differentially methylated regions (hyper-DMRs) in Tet2KD/KDEzh2Delta/Delta MDS hematopoietic stem/progenitor cells were largely distinct from those in each single mutant and correlated with transcriptional repression. Although Tet2 hypomorph was responsible for enhancer hypermethylation, the loss of Ezh2 induced hyper-DMRs that were enriched for CpG islands of polycomb targets. Notably, Ezh2 targets largely lost the H3K27me3 mark while acquiring a significantly higher level of DNA methylation than Ezh1 targets that retained the mark. These findings indicate that Ezh2 targets are the major targets of the epigenetic switch in MDS with Ezh2 insufficiency. Our results provide a detailed trail for the epigenetic drift in a well-defined MDS model and demonstrate that the combined dysfunction of epigenetic regulators cooperatively remodels the epigenome in the pathogenesis of MDS. PMID- 27694925 TI - Hyperhaploidy is a novel high-risk cytogenetic subgroup in multiple myeloma. AB - Hyperhaploid clones (24-34 chromosomes) were identified in 33 patients with multiple myeloma (MM), demonstrating a novel numerical cytogenetic subgroup. Strikingly, all hyperhaploid karyotypes were found to harbor monosomy 17p, the single most important risk stratification lesion in MM. A catastrophic loss of nearly a haploid set of chromosomes results in disomies of chromosomes 3, 5, 7, 9, 11, 15, 18, 19 and 21, the same basic set of odd-numbered chromosomes found in trisomy in hyperdiploid myeloma. All other autosomes are found in monosomy, resulting in additional clinically relevant monosomies of 1p, 6q, 13q and 16q. Hypotriploid subclones (58-68 chromosomes) were also identified in 11 of the 33 patients and represent a duplication of the hyperhaploid clone. Analysis of clones utilizing interphase fluorescence in situ hybridization (iFISH), metaphase FISH and spectral karyotyping identified either monosomy 17 or del17p in all patients. Amplification of 1q21 was identified in eight patients, demonstrating an additional high-risk marker. Importantly, our findings indicate that current iFISH strategies may be uninformative or ambiguous in the detection of these clones, suggesting this patient subgroup maybe underreported. Overall survival for patients with hyperhaploid clones was poor, with a 5-year survival rate of 23.1%. These findings identify a distinct numerical subgroup with cytogenetically defined high-risk disease. PMID- 27694926 TI - NUP98 is rearranged in 3.8% of pediatric AML forming a clinical and molecular homogenous group with a poor prognosis. AB - Pediatric acute myeloid leukemia (AML) is a rare disease whose prognosis is highly variable according to factors such as chromosomal abnormalities. Recurrent genomic rearrangements are detected in half of pediatric AML by karyotype. NUcleoPorin 98 (NUP98) gene is rearranged with 31 different fusion partner genes. These rearrangements are frequently undetected by conventional cytogenetics, as the NUP98 gene is located at the end of the chromosome 11 short arm (11p15). By screening a series of 574 pediatric AML, we detected a NUP98 rearrangement in 22 cases (3.8%), a frequency similar to CBFB-MYH11 fusion gene (4.0%). The most frequent NUP98 fusion gene partner is NSD1. These cases are homogeneous regarding their biological and clinical characteristics, and associated with bad prognosis only improved by bone marrow transplantation. We detailed the biological characteristics of these AML by exome sequencing which demonstrated few recurrent mutations (FLT3 ITD, WT1, CEBPA, NBPF14, BCR and ODF1). The analysis of the clonal structure in these cases suggests that the mutation order in the NUP98 rearranged pediatric AML begins with the NUP98 rearrangement leading to epigenetic dysregulations then followed by mutations of critical hematopoietic transcription factors and finally, activation of the FLT3 signaling pathway.

PMID- 27694927 TI - A genome-wide association study identifies risk loci for childhood acute lymphoblastic leukemia at 10q26.13 and 12q23.1. AB - Genome-wide association studies (GWASs) have shown that common genetic variation contributes to the heritable risk of childhood acute lymphoblastic leukemia (ALL). To identify new susceptibility loci for the largest subtype of ALL, B-cell precursor ALL (BCP-ALL), we conducted a meta-analysis of two GWASs with imputation using 1000 Genomes and UK10K Project data as reference (totaling 1658 cases and 7224 controls). After genotyping an additional 2525 cases and 3575 controls, we identify new susceptibility loci for BCP-ALL mapping to 10q26.13 (rs35837782, LHPP, P=1.38 * 10-11) and 12q23.1 (rs4762284, ELK3, P=8.41 * 10-9). We also provide confirmatory evidence for the existence of independent risk loci at 9p21.3, but show that the association marked by rs77728904 can be accounted for by linkage disequilibrium with the rare high-impact CDKN2A p.Ala148Thr variant rs3731249. Our data provide further insights into genetic susceptibility to ALL and its biology. PMID- 27694929 TI - Distinct surveillance pathway for immunopathology during acute infection via autophagy and SR-BI. AB - The mechanisms protecting from immunopathology during acute bacterial infections are incompletely known. We found that in response to apoptotic immune cells and live or dead Listeria monocytogenes scavenger receptor BI (SR-BI), an anti atherogenic lipid exchange mediator, activated internalization mechanisms with characteristics of macropinocytosis and, assisted by Golgi fragmentation, initiated autophagic responses. This was supported by scavenger receptor-induced local increases in membrane cholesterol concentrations which generated lipid domains particularly in cell extensions and the Golgi. SR-BI was a key driver of beclin-1-dependent autophagy during acute bacterial infection of the liver and spleen. Autophagy regulated tissue infiltration of neutrophils, suppressed accumulation of Ly6C+ (inflammatory) macrophages, and prevented hepatocyte necrosis in the core of infectious foci. Perifocal levels of Ly6C+ macrophages and Ly6C- macrophages were unaffected, indicating predominant regulation of the focus core. SR-BI-triggered autophagy promoted co-elimination of apoptotic immune cells and dead bacteria but barely influenced bacterial sequestration and survival or inflammasome activation, thus exclusively counteracting damage inflicted by immune responses. Hence, SR-BI- and autophagy promote a surveillance pathway that partially responds to products of antimicrobial defenses and selectively prevents immunity-induced damage during acute infection. Our findings suggest that control of infection-associated immunopathology can be based on a unified defense operation. PMID- 27694930 TI - Low Concentration of Sodium Butyrate from Ultrabraid+NaBu suture, Promotes Angiogenesis and Tissue Remodelling in Tendon-bones Injury. AB - Sodium butyrate (NaBu), a form of short-chain fatty acid (SCFA), acts classically as a potent anti-angiogenic agent in tumour angiogenesis models, some authors demonstrated that low concentrations of NaBu may contribute to healing of tendon bone injury in part at least through promotion of tissue remodelling. Here, we investigated the effects of low-range concentrations of NaBu using in vitro and in vivo assays using angiogenesis as the primary outcome measure and the mechanisms through which it acts. We demonstrated that NaBu, alone or perfused from the UltraBraid+NaBu suture was pro-angiogenic at very low-range doses promoting migration, tube formation and cell invasion in bovine aortic endothelial cells (BAECs). Furthermore, cell exposure to low NaBu concentrations increased expression of proteins involved in angiogenic cell signalling, including p-PKCbeta1, p-FAK, p-ERK1/2, p-NFkappabeta, p-PLCgamma1 and p-VEGFR2. In addition, inhibitors of both VEGFR2 and PKCbeta1 blocked the angiogenic response. In in vivo assays, low concentrations of NaBu induced neovascularization in sponge implants in mice, evidenced by increased numbers of vessels and haemoglobin content in these implants. The findings in this study indicate that low concentrations of NaBu could be an important compound to stimulate angiogenesis at a site where vasculature is deficient and healing is compromised. PMID- 27694931 TI - Zika viral dynamics and shedding in rhesus and cynomolgus macaques. AB - Infection with Zika virus has been associated with serious neurological complications and fetal abnormalities. However, the dynamics of viral infection, replication and shedding are poorly understood. Here we show that both rhesus and cynomolgus macaques are highly susceptible to infection by lineages of Zika virus that are closely related to, or are currently circulating in, the Americas. After subcutaneous viral inoculation, viral RNA was detected in blood plasma as early as 1 d after infection. Viral RNA was also detected in saliva, urine, cerebrospinal fluid (CSF) and semen, but transiently in vaginal secretions. Although viral RNA during primary infection was cleared from blood plasma and urine within 10 d, viral RNA was detectable in saliva and seminal fluids until the end of the study, 3 weeks after the resolution of viremia in the blood. The control of primary Zika virus infection in the blood was correlated with rapid innate and adaptive immune responses. We also identified Zika RNA in tissues, including the brain and male and female reproductive tissues, during early and late stages of infection. Re-infection of six animals 45 d after primary infection with a heterologous strain resulted in complete protection, which suggests that primary Zika virus infection elicits protective immunity. Early invasion of Zika virus into the nervous system of healthy animals and the extent and duration of shedding in saliva and semen underscore possible concern for additional neurologic complications and nonarthropod-mediated transmission in humans. PMID- 27694932 TI - Hyaluronan and TLR4 promote surfactant-protein-C-positive alveolar progenitor cell renewal and prevent severe pulmonary fibrosis in mice. AB - Successful recovery from lung injury requires the repair and regeneration of alveolar epithelial cells to restore the integrity of gas-exchanging regions within the lung and preserve organ function. Improper regeneration of the alveolar epithelium is often associated with severe pulmonary fibrosis, the latter of which involves the recruitment and activation of fibroblasts, as well as matrix accumulation. Type 2 alveolar epithelial cells (AEC2s) are stem cells in the adult lung that contribute to the lung repair process. The mechanisms that regulate AEC2 renewal are incompletely understood. We provide evidence that expression of the innate immune receptor Toll-like receptor 4 (TLR4) and the extracellular matrix glycosaminoglycan hyaluronan (HA) on AEC2s are important for AEC2 renewal, repair of lung injury and limiting the extent of fibrosis. Either deletion of TLR4 or HA synthase 2 in surfactant-protein-C-positive AEC2s leads to impaired renewal capacity, severe fibrosis and mortality. Furthermore, AEC2s from patients with severe pulmonary fibrosis have reduced cell surface HA and impaired renewal capacity, suggesting that HA and TLR4 are key contributors to lung stem cell renewal and that severe pulmonary fibrosis is the result of distal epithelial stem cell failure. PMID- 27694933 TI - Classification and characterization of microsatellite instability across 18 cancer types. AB - Microsatellite instability (MSI), the spontaneous loss or gain of nucleotides from repetitive DNA tracts, is a diagnostic phenotype for gastrointestinal, endometrial, and colorectal tumors, yet the landscape of instability events across a wider variety of cancer types remains poorly understood. To explore MSI across malignancies, we examined 5,930 cancer exomes from 18 cancer types at more than 200,000 microsatellite loci and constructed a genomic classifier for MSI. We identified MSI-positive tumors in 14 of the 18 cancer types. We also identified loci that were more likely to be unstable in particular cancer types, resulting in specific instability signatures that involved cancer-associated genes, suggesting that instability patterns reflect selective pressures and can potentially identify novel cancer drivers. We also observed a correlation between survival outcomes and the overall burden of unstable microsatellites, suggesting that MSI may be a continuous, rather than discrete, phenotype that is informative across cancer types. These analyses offer insight into conserved and cancer specific properties of MSI and reveal opportunities for improved methods of clinical MSI diagnosis and cancer gene discovery.

AB - A comprehensive understanding of molecular transport within nanoporous materials remains elusive in a broad variety of engineering and biomedical applications. Here, experiments and atomistic simulations are synergically used to elucidate the non-trivial interplay between nanopore hydrophilicity and surface barriers on the overall water transport through zeolite crystals. At these nanometre-length scales, these results highlight the dominating effect of surface imperfections with reduced permeability on the overall water transport. A simple diffusion resistance model is shown to be sufficient to capture the effects of both intracrystalline and surface diffusion resistances, thus properly linking simulation to experimental evidence. This work suggests that future experimental work should focus on eliminating/overcoming these surface imperfections, which promise an order of magnitude improvement in permeability. PMID- 27694934 TI - Translocation and dissemination of commensal bacteria in post-stroke infection. AB - Bacterial infection is highly prevalent in patients who have had a stroke. Despite the potential contribution of micro-aspiration in post-stroke pneumonia, we found that the majority of the microorganisms detected in the patients who developed infections after having a stroke were common commensal bacteria that normally reside in the intestinal tracts. In a mouse model of ischemic stroke, post-stroke infection was only observed in mice that were born and raised in specific-pathogen-free facilities; this was not seen in mice that were born and raised in germ-free facilities. Using high-throughput 16S rRNA gene amplicon sequencing and bioinformatics analyses, we provide evidence demonstrating that the source of the bacteria forming the microbial community in the lungs of post stroke mice was indeed the host small intestine. Additionally, stroke-induced gut barrier permeability and dysfunction preceded the dissemination of orally inoculated bacteria to peripheral tissues. This study identifies a novel pathway in which stroke promotes the translocation and dissemination of selective strains of bacteria that originated from the host gut microbiota. PMID- 27694936 TI - Dissecting the regulation rules of cancer-related miRNAs based on network analysis. AB - miRNAs (microRNAs) are a set of endogenous and small non-coding RNAs which specifically induce degradation of target mRNAs or inhibit protein translation to control gene expression. Obviously, aberrant miRNA expression in human cells will lead to a serious of changes in protein-protein interaction network (PPIN), thus to activate or inactivate some pathways related to various diseases, especially carcinogenesis. In this study, we systematically constructed the miRNA-regulated co-expressed protein-protein interaction network (CePPIN) for 17 cancers firstly. We investigated the topological parameters and functional annotation for the proteins in CePPIN, especially for those miRNA targets. We found that targets regulated by more miRNAs tend to play a more important role in the forming process of cancers. We further elucidated the miRNA regulation rules in PPIN from a more systematical perspective. By GO and KEGG pathway analysis, miRNA targets are involved in various cellular processes mostly related to cell cycle, such as cell proliferation, growth, differentiation, etc. Through the Pfam classification, we found that miRNAs belonging to the same family tend to have targets from the same family which displays the synergistic function of these miRNAs. Finally, the case study on miR-519d and miR-21-regulated sub-network was performed to support our findings. PMID- 27694938 TI - Large Fizeau's light-dragging effect in a moving electromagnetically induced transparent medium. AB - As one of the most influential experiments on the development of modern macroscopic theory from Newtonian mechanics to Einstein's special theory of relativity, the phenomenon of light dragging in a moving medium has been discussed and observed extensively in different types of systems. To have a significant dragging effect, the long duration of light travelling in the medium is preferred. Here we demonstrate a light-dragging experiment in an electromagnetically induced transparent cold atomic ensemble and enhance the dragging effect by at least three orders of magnitude compared with the previous experiments. With a large enhancement of the dragging effect, we realize an atom based velocimeter that has a sensitivity two orders of magnitude higher than the velocity width of the atomic medium used. Such a demonstration could pave the way for motional sensing using the collective state of atoms in a room temperature vapour cell or solid state material. PMID- 27694937 TI - Sensing surface mechanical deformation using active probes driven by motor proteins. AB - Studying mechanical deformation at the surface of soft materials has been challenging due to the difficulty in separating surface deformation from the bulk elasticity of the materials. Here, we introduce a new approach for studying the surface mechanical deformation of a soft material by utilizing a large number of self-propelled microprobes driven by motor proteins on the surface of the material. Information about the surface mechanical deformation of the soft material is obtained through changes in mobility of the microprobes wandering across the surface of the soft material. The active microprobes respond to mechanical deformation of the surface and readily change their velocity and direction depending on the extent and mode of surface deformation. This highly parallel and reliable method of sensing mechanical deformation at the surface of soft materials is expected to find applications that explore surface mechanics of soft materials and consequently would greatly benefit the surface science. PMID- 27694939 TI - Attached biofilms and suspended aggregates are distinct microbial lifestyles emanating from differing hydraulics. AB - Small-scale hydraulics affects microbial behaviour at the cell level1, trophic interactions in marine aggregates2 and the physical structure and function of stream biofilms3,4. However, it remains unclear how hydraulics, predictably changing from small streams to large rivers, impacts the structure and biodiversity of complex microbial communities in these ecosystems. Here, we present experimental evidence unveiling hydraulics as a hitherto poorly recognized control of microbial lifestyle differentiation in fluvial ecosystems. Exposing planktonic source communities from stream and floodplain ecosystems to different hydraulic environments revealed strong selective hydraulic pressures but only minor founder effects on the differentiation of attached biofilms and suspended aggregates and their biodiversity dynamics. Key taxa with a coherent phylogenetic underpinning drove this differentiation. Only a few resident and phylogenetically related taxa formed the backbone of biofilm communities, whereas numerous resident taxa characterized aggregate communities. Our findings unveil fundamental differences between biofilms and aggregates and build the basis for a mechanistic understanding of how hydraulics drives the distribution of microbial diversity along the fluvial continuum5-7. PMID- 27694940 TI - Organism-like formation of Schistosoma hemozoin and its function suggest a mechanism for anti-malarial action of artemisinin. AB - The current theories of antimalarial mechanism of artemisinin are inadequate to fully explain the observed effects. In our study, "organism-like" formation of Schistosoma hemozoin granules by attaching to and utilizing erythrocytes to form new ones was observed. This indicates that heme iron is transferred from erythrocytes to hemozoin granules during their formation. However, as a disposal product of heme detoxification, these granules are not completely expelled from the Schistosoma gut, but decomposed again between microvilli in the posterior portion of the gut to transfer iron to eggs. Based on the function of iron transport supported by our observation of the unique process of Schistosoma hemozoin formation, here we propose a new viewpoint of antimalarial mechanism of artemisinin, which emphasizes the final outcome, i.e., interference of iron utilization in parasites by artemisinin, instead of focusing on the mode of interaction between artemisinin and heme or hemozoin. This suggests that artemisinin and its endoperoxides derivatives likely hit the Achilles' heel of hemozoin-producing and iron-dependent organisms. PMID- 27694941 TI - Extracellular IL-33 cytokine, but not endogenous nuclear IL-33, regulates protein expression in endothelial cells. AB - IL-33 is a nuclear cytokine from the IL-1 family that plays important roles in health and disease. Extracellular IL-33 activates a growing number of target cells, including group 2 innate lymphoid cells, mast cells and regulatory T cells, but it remains unclear whether intracellular nuclear IL-33 has additional functions in the nucleus. Here, we used a global proteomic approach based on high resolution mass spectrometry to compare the extracellular and intracellular roles of IL-33 in primary human endothelial cells, a major source of IL-33 protein in human tissues. We found that exogenous extracellular IL-33 cytokine induced expression of a distinct set of proteins associated with inflammatory responses in endothelial cells. In contrast, knockdown of endogenous nuclear IL-33 expression using two independent RNA silencing strategies had no reproducible effect on the endothelial cell proteome. These results suggest that IL-33 acts as a cytokine but not as a nuclear factor regulating gene expression in endothelial cells. PMID- 27694942 TI - Histone variant H3F3A promotes lung cancer cell migration through intronic regulation. AB - Although several somatic single nucleotide variations in histone H3.3 have been investigated as cancer drivers, other types of aberration have not been well studied. Here, we demonstrate that overexpression of H3F3A, encoding H3.3, is associated with lung cancer progression and promotes lung cancer cell migration by activating metastasis-related genes. H3.3 globally activates gene expression through the occupation of intronic regions in lung cancer cells. Moreover, H3.3 binding regions show characteristics of regulatory DNA elements. We show that H3.3 is deposited at a specific intronic region of GPR87, where it modifies the chromatin status and directly activates GPR87 transcription. The expression levels of H3F3A and GPR87, either alone or in combination, are robust prognostic markers for early-stage lung cancer, and may indicate potential for the development of treatments involving GPR87 antagonists. In summary, our results demonstrate that intronic regulation by H3F3A may be a target for the development of novel therapeutic strategies. PMID- 27694943 TI - Outcome of AL amyloidosis after high-dose melphalan and autologous stem cell transplantation in Sweden, long-term results from all patients treated in 1994 2009. AB - High-dose melphalan and autologous stem cell transplantation (HDM/ASCT) is widely used in immunoglobulin light chain (AL) amyloidosis, but the benefit is debated mainly because of the high treatment-related mortality (24% in a randomised study comparing HDM/ASCT with oral melphalan/dexamethasone). We report here on the long term outcome of all patients treated with HDM/ASCT for AL amyloidosis in Sweden between 1994 and 2009. Seventy-two patients were treated at eight Swedish centres. Median follow-up was 67.5 months. At least partial response (organ or haematological) was seen in 64% of the patients. Median overall survival was 98 months or 8.2 years, with 5-year survival 63.9% and 10-year survival 43.4%. In patients with cardiac involvement or multiple organ involvement, survival was significantly shorter, median overall survival 49 and 56 months, respectively. All mortality within 100 days from ASCT was 12.5% for all patients and 17.2% in the patients with cardiac involvement. For patients treated in the earlier time period (1994-2001), 100-day mortality was 23.8% compared with 7.8% in the later period (2002-2009). In conclusion, long survival times can be achieved in patients with AL amyloidosis treated with HDM/ASCT, also in smaller centres. Early mortality is high, but with a decreasing trend over time. PMID- 27694944 TI - Efficient Synthesis of Ethanol from CH4 and Syngas on a Cu-Co/TiO2 Catalyst Using a Stepwise Reactor. AB - Ethanol synthesis from CH4 and syngas on a Cu-Co/TiO2 catalyst is studied using experiments, density functional theory (DFT) and microkinetic modelling. The experimental results indicate that the active sites of ethanol synthesis from CH4 and syngas are Cu and CoO, over which the ethanol selectivity is approximately 98.30% in a continuous stepwise reactor. DFT and microkinetic modelling results show that *CH3 is the most abundant species and can be formed from *CH4 dehydrogenation or through the process of *CO hydrogenation. Next, the insertion of *CO into *CH3 forms *CH3CO. Finally, ethanol is formed through *CH3CO and *CH3COH hydrogenation. According to our results, small particles of metallic Cu and CoO as well as a strongly synergistic effect between metallic Cu and CoO are beneficial for ethanol synthesis from CH4 and syngas on a Cu-Co/TiO2 catalyst. PMID- 27694945 TI - Genomic prediction contributing to a promising global strategy to turbocharge gene banks. AB - The 7.4 million plant accessions in gene banks are largely underutilized due to various resource constraints, but current genomic and analytic technologies are enabling us to mine this natural heritage. Here we report a proof-of-concept study to integrate genomic prediction into a broad germplasm evaluation process. First, a set of 962 biomass sorghum accessions were chosen as a reference set by germplasm curators. With high throughput genotyping-by-sequencing (GBS), we genetically characterized this reference set with 340,496 single nucleotide polymorphisms (SNPs). A set of 299 accessions was selected as the training set to represent the overall diversity of the reference set, and we phenotypically characterized the training set for biomass yield and other related traits. Cross validation with multiple analytical methods using the data of this training set indicated high prediction accuracy for biomass yield. Empirical experiments with a 200-accession validation set chosen from the reference set confirmed high prediction accuracy. The potential to apply the prediction model to broader genetic contexts was also examined with an independent population. Detailed analyses on prediction reliability provided new insights into strategy optimization. The success of this project illustrates that a global, cost effective strategy may be designed to assess the vast amount of valuable germplasm archived in 1,750 gene banks. PMID- 27694946 TI - A proteinaceous organic matrix regulates carbonate mineral production in the marine teleost intestine. AB - Marine teleost fish produce CaCO3 in their intestine as part of their osmoregulatory strategy. This precipitation is critical for rehydration and survival of the largest vertebrate group on earth, yet the molecular mechanisms that regulate this reaction are unknown. Here, we isolate and characterize an organic matrix associated with the intestinal precipitates produced by Gulf toadfish (Opsanus beta). Toadfish precipitates were purified using two different methods, and the associated organic matrix was extracted. Greater than 150 proteins were identified in the isolated matrix by mass spectrometry and subsequent database searching using an O. beta transcriptomic sequence library produced here. Many of the identified proteins were enriched in the matrix compared to the intestinal fluid, and three showed no substantial homology to any previously characterized protein in the NCBI database. To test the functionality of the isolated matrix, a micro-modified in vitro calcification assay was designed, which revealed that low concentrations of isolated matrix substantially promoted CaCO3 production, where high concentrations showed an inhibitory effect. High concentrations of matrix also decreased the incorporation of magnesium into the forming mineral, potentially providing an explanation for the variability in magnesium content observed in precipitates produced by different fish species. PMID- 27694948 TI - Changes in litter quality induced by nutrient addition alter litter decomposition in an alpine meadow on the Qinghai-Tibet Plateau. AB - The effects of nitrogen (N) and phosphorus (P) addition on litter decomposition are poorly understood in Tibetan alpine meadows. Leaf litter was collected from plots within a factorial N * P addition experiment and allowed to decompose over 708 days in an unfertilized plot to determine the effects of N and/or P addition on litter decomposition. Results showed that nutrient addition significantly affected initial P and P-related biochemical properties of litter from all four species. However, the responses of litter N and N-related biochemical properties to nutrient addition were quite species-specific. Litter C decomposition and N release were species-specific. However, N and P addition significantly affected litter P release. Ratios of Hemicellulose + Cellulose to N and P were significantly related to litter C decomposition; C:N ratio was a determinant of litter N release; and C:P and (Hemicellulose + Cellulose):P controlled litter P release. Overall, litter C decomposition was controlled by litter quality of different plant species, and strongly affected by P addition. Increasing N availability is likely to affect litter C decomposition more indirectly by shifting plant species composition than directly by improving litter quality, and may accelerate N and P cycles, but shift the ecosystem to P limitation. PMID- 27694947 TI - Organization of olfactory centres in the malaria mosquito Anopheles gambiae. AB - Mosquitoes are vectors for multiple infectious human diseases and use a variety of sensory cues (olfactory, temperature, humidity and visual) to locate a human host. A comprehensive understanding of the circuitry underlying sensory signalling in the mosquito brain is lacking. Here we used the Q-system of binary gene expression to develop transgenic lines of Anopheles gambiae in which olfactory receptor neurons expressing the odorant receptor co-receptor (Orco) gene are labelled with GFP. These neurons project from the antennae and maxillary palps to the antennal lobe (AL) and from the labella on the proboscis to the suboesophageal zone (SEZ), suggesting integration of olfactory and gustatory signals occurs in this brain region. We present detailed anatomical maps of olfactory innervations in the AL and the SEZ, identifying glomeruli that may respond to human body odours or carbon dioxide. Our results pave the way for anatomical and functional neurogenetic studies of sensory processing in mosquitoes. PMID- 27694949 TI - A quorum-sensing signal promotes host tolerance training through HDAC1-mediated epigenetic reprogramming. AB - The mechanisms by which pathogens evade elimination without affecting host fitness are not well understood. For the pathogen Pseudomonas aeruginosa, this evasion appears to be triggered by excretion of the quorum-sensing molecule 2 aminoacetophenone, which dampens host immune responses and modulates host metabolism, thereby enabling the bacteria to persist at a high burden level. Here, we examined how 2-aminoacetophenone trains host tissues to become tolerant to a high bacterial burden, without compromising host fitness. We found that 2 aminoacetophenone regulates histone deacetylase 1 expression and activity, resulting in hypo-acetylation of lysine 18 of histone H3 at pro-inflammatory cytokine loci. Specifically, 2-aminoacetophenone induced reprogramming of immune cells occurs via alterations in histone acetylation of immune cytokines in vivo and in vitro. This host epigenetic reprograming, which was maintained for up to 7 days, dampened host responses to subsequent exposure to 2-aminoacetophenone or other unrelated pathogen-associated molecules. The process was found to involve a distinct molecular mechanism of host chromatin regulation. Inhibition of histone deacetylase 1 prevented the immunomodulatory effects of 2-aminoacetophenone. These observations provide the first mechanistic example of a quorum-sensing molecule regulating a host epigenome to enable tolerance of infection. These insights have enormous potential for developing preventive treatments against bacterial infections. PMID- 27694950 TI - Multi-Pass Adaptive Voting for Nuclei Detection in Histopathological Images. AB - Nuclei detection is often a critical initial step in the development of computer aided diagnosis and prognosis schemes in the context of digital pathology images. While over the last few years, a number of nuclei detection methods have been proposed, most of these approaches make idealistic assumptions about the staining quality of the tissue. In this paper, we present a new Multi-Pass Adaptive Voting (MPAV) for nuclei detection which is specifically geared towards images with poor quality staining and noise on account of tissue preparation artifacts. The MPAV utilizes the symmetric property of nuclear boundary and adaptively selects gradient from edge fragments to perform voting for a potential nucleus location. The MPAV was evaluated in three cohorts with different staining methods: Hematoxylin &Eosin, CD31 &Hematoxylin, and Ki-67 and where most of the nuclei were unevenly and imprecisely stained. Across a total of 47 images and nearly 17,700 manually labeled nuclei serving as the ground truth, MPAV was able to achieve a superior performance, with an area under the precision-recall curve (AUC) of 0.73. Additionally, MPAV also outperformed three state-of-the-art nuclei detection methods, a single pass voting method, a multi-pass voting method, and a deep learning based method. PMID- 27694951 TI - Prognostic Significance of Neutrophil to Lymphocyte Ratio in Oncologic Outcomes of Cholangiocarcinoma: A Meta-analysis. AB - Increasing evidence indicates that the neutrophil to lymphocyte ratio (NLR) is a useful biomarker of long-term outcomes in patients with cholangiocarcinoma. However, the prognostic role of NLR in patients with cholangiocarcinoma remains unclear. Thus, the current meta-analysis was undertaken to clarify the correlation between NLR and overall survival (OS) in cholangiocarcinoma, and a comprehensive literature research was conducted to understand the association of NLR and prognosis of cholangiocarcinoma. The hazard ratio (HR) with 95% confidence interval (CI) was used to assess OS. The synthesized HR of 1.449 (95% CI: 1.296-1.619, P < 0.001) indicated that a high NLR had an unfavourable effect on OS. Overall, this meta-analysis suggested that elevated preoperative NLR is associated with poorer rates of survival in cholangiocarcinoma patients. PMID- 27694952 TI - The backtracking survey propagation algorithm for solving random K-SAT problems. AB - Discrete combinatorial optimization has a central role in many scientific disciplines, however, for hard problems we lack linear time algorithms that would allow us to solve very large instances. Moreover, it is still unclear what are the key features that make a discrete combinatorial optimization problem hard to solve. Here we study random K-satisfiability problems with K=3,4, which are known to be very hard close to the SAT-UNSAT threshold, where problems stop having solutions. We show that the backtracking survey propagation algorithm, in a time practically linear in the problem size, is able to find solutions very close to the threshold, in a region unreachable by any other algorithm. All solutions found have no frozen variables, thus supporting the conjecture that only unfrozen solutions can be found in linear time, and that a problem becomes impossible to solve in linear time when all solutions contain frozen variables. PMID- 27694953 TI - Effective pinning energy landscape perturbations for propagating magnetic domain walls. AB - The interaction between a magnetic domain wall and a pinning site is explored in a planar nanowire using micromagnetics to reveal perturbations of the pinning energetics for propagating domain walls. Numerical simulations in the high damping 'quasi-static' and low damping 'dynamic' regimes are compared and show clear differences in de-pinning fields, indicating that dynamical micromagnetic models, which incorporate precessionally limited magnetization processes, are needed to understand domain wall pinning. Differences in the micromagnetic domain wall structure strongly influence the pinning and show periodic behaviour with increasing applied field associated with Walker breakdown. In the propagating regime pinning is complicated. PMID- 27694954 TI - Inhibition of Rac1 GTPase activity affects porcine oocyte maturation and early embryo development. AB - Mammalian oocyte asymmetric division relies on the eccentric positioning of the spindle, resulting in the polar body formation. Small signaling G protein Rac1 is a member of GTPases, which regulates a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases. However, effects of Rac1 on the porcine oocyte maturation and early embryo development are not fully understood. In present study we investigated the role of Rac1 in oocyte maturation and embryo cleavage. We first found that Rac1 localized at the cortex of the porcine oocytes, and disrupting the Rac1 activities by treating with NSC 23766 led to the failure of polar body emission. In addition, a majority of treated oocytes exhibited abnormal spindle morphology, indicating that Rac1 may involve into porcine oocyte spindle formation. This might be due to the regulation of Rac1 on MAPK, since p MAPK expression decreased after NSC 23766 treatments. Moreover, we found that the position of most meiotic spindles in treated oocytes were away from the cortex, indicating the roles of Rac1 on meiotic spindle positioning. Our results also showed that inhibition of Rac1 activity caused the failure of early embryo development. Therefore, our study showed the critical roles of Rac1 GTPase on porcine oocyte maturation and early embryo cleavage. PMID- 27694955 TI - Default mode network and frontolimbic gray matter abnormalities in patients with borderline personality disorder: A voxel-based meta-analysis. AB - Specific frontolimbic abnormalities are hypothesized to underlie the etiology of borderline personality disorder (BPD). However, findings from neuroimaging studies were inconsistent. In the current study, we aimed to provide a complete overview of cerebral microstructural alterations in gray matter (GM) of BPD patients. A total of 11 studies were enrolled, comprising 275 BPD patients and 290 healthy controls (HCs). A meta-analysis was conduct to quantitatively estimate regional GM abnormalities in BPD patients using the seed-based d mapping (SDM). Meta-regression was also conducted. Compared with HCs, the BPD patients exhibited increased GM mainly in bilateral supplementary motor area extending to right posterior cingulated cortex (PCC) and bilateral primary motor cortex, right middle frontal gyrus (MFG), and the bilateral precuneus extending to bilateral PCC. Decreased GM was identified in bilateral middle temporal gyri, right inferior frontal gyrus extending to right insular, left hippocampus and left superior frontal gyrus extending to left medial orbitofrontal cortex. The mean age of BPD patients were found nagativly associated with GM alterations in right MFG. Our findings suggested that BPD patients have significantly GM abnormalities in the default mode network and frontolimbic circuit. Our results provided further evidences in elucidating the underline neural mechanisms of BPD. PMID- 27694956 TI - Prediction and evaluation of the lipase inhibitory activities of tea polyphenols with 3D-QSAR models. AB - The extraordinary hypolipidemic effects of polyphenolic compounds from tea have been confirmed in our previous study. To gain compounds with more potent activities, using the conformations of the most active compound revealed by molecular docking, a 3D-QSAR pancreatic lipase inhibitor model with good predictive ability was established and validated by CoMFA and CoMISA methods. With good statistical significance in CoMFA (r2cv = 0.622, r2 = 0.956, F = 261.463, SEE = 0.096) and CoMISA (r2cv = 0.631, r2 = 0.932, F = 75.408, SEE = 0.212) model, we summarized the structure-activity relationship between polyphenolic compounds and pancreatic lipase inhibitory activities and find the bulky substituents in R2, R4 and R5, hydrophilic substituents in R1 and electron withdrawing groups in R2 are the key factors to enhance the lipase inhibitory activities. Under the guidance of the 3D-QSAR results, (2R,3R,2'R,3'R) desgalloyloolongtheanin-3,3'-O-digallate (DOTD), a potent lipase inhibitor with an IC50 of 0.08 MUg/ml, was obtained from EGCG oxidative polymerization catalyzed by crude polyphenol oxidase. Furthermore, DOTD was found to inhibit lipid absorption in olive oil-loaded rats, which was related with inhibiting the activities of lipase in the intestinal mucosa and contents. PMID- 27694957 TI - The site of water stress governs the pattern of ABA synthesis and transport in peanut. AB - Abscisic acid (ABA) is one of the most important phytohormones involved in stress responses in plants. However, knowledge of the effect on ABA distribution and transport of water stress at different sites on the plant is limited. In this study, water stress imposed on peanut leaves or roots by treatment with PEG 6000 is termed "leaf stress" or "root stress", respectively. Immunoenzyme localization technolony was first used to detect ABA distribution in peanut. Under root stress, ABA biosynthesis and distribution level were all more pronounced in root than in leaf. However, ABA transport and the ability to induce stomatal closure were still better in leaf than in root during root stress; However, ABA biosynthesis initially increased in leaf, then rapidly accumulated in the vascular cambium of leaves and induced stomatal closure under leaf stress; ABA produced in root tissues was also transported to leaf tissues to maintain stomatal closure. The vascular system was involved in the coordination and integration of this complex regulatory mechanism for ABA signal accumulation. Water stress subject to root or leaf results in different of ABA biosynthesis and transport ability that trigger stoma close in peanut. PMID- 27694958 TI - Reference-based phasing using the Haplotype Reference Consortium panel. AB - Haplotype phasing is a fundamental problem in medical and population genetics. Phasing is generally performed via statistical phasing in a genotyped cohort, an approach that can yield high accuracy in very large cohorts but attains lower accuracy in smaller cohorts. Here we instead explore the paradigm of reference based phasing. We introduce a new phasing algorithm, Eagle2, that attains high accuracy across a broad range of cohort sizes by efficiently leveraging information from large external reference panels (such as the Haplotype Reference Consortium; HRC) using a new data structure based on the positional Burrows Wheeler transform. We demonstrate that Eagle2 attains a ~20* speedup and ~10% increase in accuracy compared to reference-based phasing using SHAPEIT2. On European-ancestry samples, Eagle2 with the HRC panel achieves >2* the accuracy of 1000 Genomes-based phasing. Eagle2 is open source and freely available for HRC based phasing via the Sanger Imputation Service and the Michigan Imputation Server. PMID- 27694959 TI - The effect of host genetics on the gut microbiome. AB - The gut microbiome is affected by multiple factors, including genetics. In this study, we assessed the influence of host genetics on microbial species, pathways and gene ontology categories, on the basis of metagenomic sequencing in 1,514 subjects. In a genome-wide analysis, we identified associations of 9 loci with microbial taxonomies and 33 loci with microbial pathways and gene ontology terms at P < 5 * 10-8. Additionally, in a targeted analysis of regions involved in complex diseases, innate and adaptive immunity, or food preferences, 32 loci were identified at the suggestive level of P < 5 * 10-6. Most of our reported associations are new, including genome-wide significance for the C-type lectin molecules CLEC4F-CD207 at 2p13.3 and CLEC4A-FAM90A1 at 12p13. We also identified association of a functional LCT SNP with the Bifidobacterium genus (P = 3.45 * 10 8) and provide evidence of a gene-diet interaction in the regulation of Bifidobacterium abundance. Our results demonstrate the importance of understanding host-microbe interactions to gain better insight into human health. PMID- 27694960 TI - Association of host genome with intestinal microbial composition in a large healthy cohort. AB - Intestinal microbiota is known to be important in health and disease. Its composition is influenced by both environmental and host factors. Few large-scale studies have evaluated the association between host genetic variation and the composition of microbiota. We recruited a cohort of 1,561 healthy individuals, of whom 270 belong in 123 families, and found that almost one-third of fecal bacterial taxa were heritable. In addition, we identified 58 SNPs associated with the relative abundance of 33 taxa in 1,098 discovery subjects. Among these, four loci were replicated in a second cohort of 463 subjects: rs62171178 (nearest gene UBR3) associated with Rikenellaceae, rs1394174 (CNTN6) associated with Faecalibacterium, rs59846192 (DMRTB1) associated with Lachnospira, and rs28473221 (SALL3) associated with Eubacterium. After correction for multiple testing, 6 of the 58 associations remained significant, one of which replicated. These results identify associations between specific genetic variants and the gut microbiome. PMID- 27694963 TI - A role for the asexual spores in infection of Fraxinus excelsior by the ash dieback fungus Hymenoscyphus fraxineus. AB - The invasive pathogen, ash dieback fungus Hymenoscyphus fraxineus, is spreading rapidly across Europe. It shows high levels of outcrossing and limited population structure, even at the epidemic front. The anamorphic (asexual) form produces prolific conidia, thought to function solely as spermatia (male gametes), facilitating gene flow between sympatric strains. Here, we show that conidia are capable of germination on ash leaves and in vitro, and can infect seedlings via leaves or soil. In leaves, germlings form structures resembling fruiting bodies. Additionally, H. fraxineus colonises ash debris and grows in soil in the absence of ash tissues. We propose an amended life-cycle in which wind-dispersed, insect vectored or water-spread conidia infect ash and may sporulate in planta, as well as in forest debris. This amplifies inoculum levels of different strains in ash stands. In combination with their function as spermatia, conidia thus act to maximise gene flow between sympatric strains, including those originally present at low inoculum. Such mixing increases evolutionary potential, as well as enhancing the likelihood of gene introgression from closely-related strains or assimilation of further genetic diversity from parental Asian populations. This scenario increases the adaptability of H. fraxineus to new climates and, indeed, onto new host species. PMID- 27694962 TI - A 3'-end structure in RNA2 of a crinivirus is essential for viral RNA synthesis and contributes to replication-associated translation activity. AB - The terminal ends in the genome of RNA viruses contain features that regulate viral replication and/or translation. We have identified a Y-shaped structure (YSS) in the 3' terminal regions of the bipartite genome of Lettuce chlorosis virus (LCV), a member in the genus Crinivirus (family Closteroviridae). The YSS is the first in this family of viruses to be determined using Selective 2' Hydroxyl Acylation Analyzed by Primer Extension (SHAPE). Using luciferase constructs/replicons, in vivo and in vitro assays showed that the 5' and YSS containing 3' terminal regions of LCV RNA1 supported translation activity. In contrast, similar regions from LCV RNA2, including those upstream of the YSS, did not. LCV RNA2 mutants with nucleotide deletions or replacements that affected the YSS were replication deficient. In addition, the YSS of LCV RNA1 and RNA2 were interchangeable without affecting viral RNA synthesis. Translation and significant replication were observed for specific LCV RNA2 replicons only in the presence of LCV RNA1, but both processes were impaired when the YSS and/or its upstream region were incomplete or altered. These results are evidence that the YSS is essential to the viral replication machinery, and contributes to replication enhancement and replication-associated translation activity in the RNA2 replicons.

AB - Potassium (K) fertilizer management is beneficial for improving growth, yield and yield components of field crops under moisture stress condition in semiarid climates. Field experiments were conducted to study the response of maize (Zea mays L., cv. Azam) to foliar and soil applied K during summer 2013 and 2014. The experiments were carried out at the Agronomy Research Farm of The University of Agriculture Peshawar, Northwest Pakistan under limited irrigation (moisture stress) condition. It was concluded from the results that application of foliar K at the rate of 1-3% and foliar Zn at the rate of 0.1-0.2% was more beneficial in terms of better growth, higher yield and yield components of maize under moisture stress condition. Early spray (vegetative stage) resulted in better growth and higher yield than late spray (reproductive stage). Soil K treated plots (rest) plots performed better than control (K not applied) in terms of improved growth, higher yield and yield components of maize crop. The results further demonstrated that increasing the rate of soil applied K up to 90 kg P ha-1 in two equal splits (50% each at sowing and knee height) improve growth and maize productivity under semiarid climates. PMID- 27694961 TI - Mutations in the HECT domain of NEDD4L lead to AKT-mTOR pathway deregulation and cause periventricular nodular heterotopia. AB - Neurodevelopmental disorders with periventricular nodular heterotopia (PNH) are etiologically heterogeneous, and their genetic causes remain in many cases unknown. Here we show that missense mutations in NEDD4L mapping to the HECT domain of the encoded E3 ubiquitin ligase lead to PNH associated with toe syndactyly, cleft palate and neurodevelopmental delay. Cellular and expression data showed sensitivity of PNH-associated mutants to proteasome degradation. Moreover, an in utero electroporation approach showed that PNH-related mutants and excess wild-type NEDD4L affect neurogenesis, neuronal positioning and terminal translocation. Further investigations, including rapamycin-based experiments, found differential deregulation of pathways involved. Excess wild type NEDD4L leads to disruption of Dab1 and mTORC1 pathways, while PNH-related mutations are associated with deregulation of mTORC1 and AKT activities. Altogether, these data provide insights into the critical role of NEDD4L in the regulation of mTOR pathways and their contributions in cortical development. PMID- 27694965 TI - Coronary artery calcium is associated with cortical thinning in cognitively normal individuals. AB - To evaluate the association between coronary artery calcium (CAC) and cortical thickness in a large sample of cognitively normal individuals, with special emphasis in determining if the association thickness has regional brain specificity and if it is mediated by white matter hyperintensities (WMH). A total of 512 participants were included in this study. CAC scores were assessed by multi-detector computed tomography. Cortical thickness was measured using a surface-based method. Linear mixed models were used to assess the association between CAC scores and cortical thickness. In fully adjusted models, increased CAC scores were associated with cortical thinning across several brain regions, which generally overlapped with the distribution of default mode network. The association between CAC scores and cortical thickness was significantly stronger in participants with moderate or severe WMH compared to those with none or mild WMH, even though CAC scores were not associated with WMH. In cognitively normal adults, CAC was associated with cortical thinning in areas related to cognitive function. This association was evident after adjusting for multiple coronary artery disease risk factors and for WMH, suggesting that CAC may be more closely related to Alzheimer's Disease-type disease rather than to cerebral small vessel disease. PMID- 27694966 TI - High sensitivity of gold nanoparticles co-doped with Gd2O3 mesoporous silica nanocomposite to nasopharyngeal carcinoma cells. AB - Nanoprobes for combined optical and magnetic resonance imaging have tremendous potential in early cancer diagnosis. Gold nanoparticles (AuNPs) co-doped with Gd2O3 mesoporous silica nanocomposite (Au/Gd@MCM-41) can produce pronounced contrast enhancement for T1 weighted image in magnetic resonance imaging (MRI). Here, we show the remarkably high sensitivity of Au/Gd@MCM-41 to the human poorly differentiated nasopharyngeal carcinoma (NPC) cell line (CNE-2) using fluorescence lifetime imaging (FLIM). The upconversion luminescences from CNE-2 and the normal nasopharyngeal (NP) cells (NP69) after uptake of Au/Gd@MCM-41 show the characteristic of two-photon-induced-radiative recombination of the AuNPs. The presence of the Gd3+ ion induces a much shorter luminescence lifetime in CNE 2 cells. The interaction between AuNPs and Gd3+ ion clearly enhances the optical sensitivity of Au/Gd@MCM-41 to CNE-2. Furthermore, the difference in the autofluorescence between CNE-2 and NP69 cells can be efficiently demonstrated by the emission lifetimes of Au/Gd@MCM-41 through the Forster energy transfers from the endogenous fluorophores to AuNPs. The results suggest that Au/Gd@MCM-41 may impart high optical resolution for the FLIM imaging that differentiates normal and high-grade precancers.

AB - Pine needles have been widely used in the development of anti-hypertensive and anti-hyperlipidemic agents and health food. However, the widespread distribution of this tree poses great obstacles to the quality control and efficacy evaluation. To facilitate the effective and rational exploitation of Masson's pine (Pinus massoniana Lamb), as well as ensure effective development of Masson's pine needles as a medicinal agent, we investigated the spatial distribution of habitat suitability and evaluated the optimal ranges of ecological factors of P. massoniana with 280 samples collected from 12 provinces in China through the evaluation of four constituents known to be effective medicinally. The results of habitat suitability evaluation were also verified by Root Mean Square Error (RMSE). Finally, five ecological factors were chosen in the establishment of a habitat suitability evaluation system. The most suitable areas for P. massoniana growth were mainly concentrated in the middle and lower reaches of the Yangtze River basin, such as Sichuan, Guizhou, and Jiangxi provinces, while the best quality needles were from Guizhou, Sichuan, and the junction area of Chongqing, Hunan, and Hubei provinces. This information revealed that suitable areas for effective constituent accumulation of Masson's pine needles accounted for only 7.41% of its distribution area. PMID- 27694968 TI - Transport of cerium oxide nanoparticles in saturated silica media: influences of operational parameters and aqueous chemical conditions. AB - This paper aimed to investigate the influences of operational parameters and aqueous chemical conditions on transport behaviors of cerium oxides nanoparticles (CeO2-NPs) in saturated silica media. Results indicated that increasing rates of attachment efficiency (alpha) were related with cationic types, and critical deposition concentration (CDC) for divalent cation (Ca2+ and Mg2+) were more than 31-fold of that for monovalent cation (Na+ and K+). Increase or reduction of electrolyte pH could both promote the mobility of CeO2-NPs in glass beads, while influence was more evident at alkaline conditions. alpha increased linearly with NPs concentrations, while decreased linearly with flow velocity in the column, and effects were related with electrolyte contents. Presence of surfactants could sharply decreased alpha, and SDS was more effective to facilitate CeO2-NPs transport than Triton X-100. With DOMs concentrations increasing, alpha firstly kept constant, then sharply declined, and finally reduced very slowly. The influence of DOMs on NPs deposition was in order of SA > HA > TA > BSA. Overall, this study revealed that aqueous chemical conditions was crucial to NPs transport in porous media, and would provide significant information for our understanding on the fate and transport of nanoparticles in natural environment. PMID- 27694969 TI - Neural Correlates of Deficits in Humor Appreciation in Gelotophobics. AB - Gelotophobics have social deficits in the form of relative humorlessness and heightened sensitivity to aggressive humor; however, little is known about the neural reward mechanisms for this group. The present study attempted to identify the neural substrates of responses to hostile and non-hostile jokes in gelotophobics and non-gelotophobics. Gelotophobics showed greater activation than did non-gelotophobics in the dorsal corticostriatal system, which comprises the dorsolateral prefrontal cortex and dorsal striatum, suggesting a higher degree of voluntary top-down cognitive control of emotion. As expected, gelotophobics showed less activation in the ventral mesocorticolimbic system (MCL) in response to both hostile and non-hostile jokes, suggesting a relative deficit in the reward system. Conversely, non-gelotophobics displayed greater activation than gelotophobics did in the MCL system, particularly for non-hostile jokes, which suggests a more robust bottom-up emotional response. In response to non-hostile jokes, non-gelotophobics showed greater activation in the ventral MCL reward system, which comprises the midbrain, amygdalae, nucleus accumbens, ventral anterior cingulate cortex, and insula. Psychophysiological interaction analyses further showed that gelotophobics exhibited diminished MCL activation in response to hostile jokes. These group differences may have important implications for our understanding of the neural correlates of social motivation and humor appreciation.

PMID- 27694970 TI - Glycine triggers a non-ionotropic activity of GluN2A-containing NMDA receptors to confer neuroprotection. AB - Ionotropic activation of NMDA receptors (NMDARs) requires agonist glutamate and co-agonist glycine. Here we show that glycine enhances the activation of cell survival-promoting kinase Akt in cultured cortical neurons in which both the channel activity of NMDARs and the glycine receptors are pre-inhibited. The effect of glycine is reduced by shRNA-mediated knockdown of GluN2A subunit containing NMDARs (GluN2ARs), suggesting that a non-ionotropic activity of GluN2ARs mediates glycine-induced Akt activation. In support of this finding, glycine enhances Akt activation in HEK293 cells over-expressing GluN2ARs. The effect of glycine on Akt activation is sensitive to the antagonist of glycine GluN1 binding site. As a functional consequence, glycine protects against excitotoxicity-induced neuronal death through the non-ionotropic activity of GluN2ARs and the neuroprotective effect is attenuated by Akt inhibition. Thus, this study reveals an unexpected role of glycine in eliciting a non-ionotropic activity of GluN2ARs to confer neuroprotection via Akt activation. PMID- 27694971 TI - The evolution of antimicrobial peptide resistance in Pseudomonas aeruginosa is shaped by strong epistatic interactions. AB - Colistin is an antimicrobial peptide that has become the only remaining alternative for the treatment of multidrug-resistant Gram-negative bacterial infections, but little is known of how clinical levels of colistin resistance evolve. We use in vitro experimental evolution and whole-genome sequencing of colistin-resistant Pseudomonas aeruginosa isolates from cystic fibrosis patients to reconstruct the molecular evolutionary pathways open for high-level colistin resistance. We show that the evolution of resistance is a complex, multistep process that requires mutation in at least five independent loci that synergistically create the phenotype. Strong intergenic epistasis limits the number of possible evolutionary pathways to resistance. Mutations in transcriptional regulators are essential for resistance evolution and function as nodes that potentiate further evolution towards higher resistance by functionalizing and increasing the effect of the other mutations. These results add to our understanding of clinical antimicrobial peptide resistance and the prediction of resistance evolution. PMID- 27694973 TI - Real-space observation of magnetic excitations and avalanche behavior in artificial quasicrystal lattices. AB - Artificial spin ice lattices have emerged as model systems for studying magnetic frustration in recent years. Most work to date has looked at periodic artificial spin ice lattices. In this paper, we observe frustration effects in quasicrystal artificial spin ice lattices that lack translational symmetry and contain vertices with different numbers of interacting elements. We find that as the lattice state changes following demagnetizing and annealing, specific vertex motifs retain low-energy configurations, which excites other motifs into higher energy configurations. Additionally, we find that unlike the magnetization reversal process for periodic artificial spin ice lattices, which occurs through 1D avalanches, quasicrystal lattices undergo reversal through a dendritic 2D avalanche mechanism. PMID- 27694974 TI - Antidepressant indatraline induces autophagy and inhibits restenosis via suppression of mTOR/S6 kinase signaling pathway. AB - Indatraline is an antidepressive agent and a non-selective monoamine transporter inhibitor that blocks the reuptake of neurotransmitters (dopamine, serotonin, and norepinephrine). In this study, we report that indatraline induces autophagy via the suppression of mTOR/S6 kinase signaling. Autophagy induction was examined by a cell-based high content screening system using LysoTracker, which was followed by monodansylcadaverine staining and transmission electron microscope observation. Indatraline increased the number of EGFP-LC3 cells expressing autophagosomes in the cytoplasm. Conversion of LC3 was further validated by immunoblotting. Indatraline induced autophagy by affecting the AMPK/mTOR/S6K signaling axis and had no influence on the PI3K/AKT/ERK signaling. Moreover, indatraline induced autophagy in smooth muscle cells (SMCs); further, it exhibited therapeutic potential for restenosis by inhibiting SMC accumulation in a rat restenosis model. These results provide new insights into the role of monoamine transporters in autophagy regulation and identify indatraline as a novel agent for inducing autophagy. PMID- 27694975 TI - Projection-type see-through holographic three-dimensional display. AB - Owing to the limited spatio-temporal resolution of display devices, dynamic holographic three-dimensional displays suffer from a critical trade-off between the display size and the visual angle. Here we show a projection-type holographic three-dimensional display, in which a digitally designed holographic optical element and a digital holographic projection technique are combined to increase both factors at the same time. In the experiment, the enlarged holographic image, which is twice as large as the original display device, projected on the screen of the digitally designed holographic optical element was concentrated at the target observation area so as to increase the visual angle, which is six times as large as that for a general holographic display. Because the display size and the visual angle can be designed independently, the proposed system will accelerate the adoption of holographic three-dimensional displays in industrial applications, such as digital signage, in-car head-up displays, smart-glasses and head-mounted displays. PMID- 27694976 TI - A universal test for gravitational decoherence. AB - Quantum mechanics and the theory of gravity are presently not compatible. A particular question is whether gravity causes decoherence. Several models for gravitational decoherence have been proposed, not all of which can be described quantum mechanically. Since quantum mechanics may need to be modified, one may question the use of quantum mechanics as a calculational tool to draw conclusions from the data of experiments concerning gravity. Here we propose a general method to estimate gravitational decoherence in an experiment that allows us to draw conclusions in any physical theory where the no-signalling principle holds, even if quantum mechanics needs to be modified. As an example, we propose a concrete experiment using optomechanics. Our work raises the interesting question whether other properties of nature could similarly be established from experimental observations alone-that is, without already having a rather well-formed theory of nature to make sense of experimental data. PMID- 27694977 TI - Modification of plant cell wall structure accompanied by enhancement of saccharification efficiency using a chemical, lasalocid sodium. AB - The cell wall is one major determinant of plant cell morphology, and is an attractive bioresource. Here, we report a novel strategy to modify plant cell wall property by small molecules. Lasalocid sodium (LS) was isolated by chemical screening to identify molecules that affect the cell morphology of tobacco BY-2 cells. LS treatment led to an increase in cell wall thickness, whilst the quantity and sugar composition of the cell wall remained unchanged in BY-2 cells. The chemical also disordered the cellular arrangement of hypocotyls of Arabidopsis plants, resulting in a decrease in hypocotyl length. LS treatment enhanced enzymatic saccharification efficiency in both BY-2 cells and Arabidopsis plants. Microarray analysis on Arabidopsis showed that exposure to LS upregulated type III peroxidase genes, of which some are involved in lignin biogenesis, and jasmonic acid response genes, and phloroglucinol staining supported the activation of lignification by the LS treatment. As jasmonic acid-mediated lignification is a typical reaction to cell wall damage, it is possible that LS induces cell wall loosening, which can trigger cell wall damage response. Thus, LS is a unique chemical for modification of cell wall and morphology through changes in cell wall architecture. PMID- 27694980 TI - Podocyte biology: Dynamic control of actin remodelling. PMID- 27694978 TI - Precision medicine from the renal cancer genome. AB - Genomics is revolutionizing our understanding of the molecular basis of renal cell carcinoma (RCC). The advent of unbiased genome-wide association studies has led to the discovery of previously unrecognized genetic predisposing factors that impact an individual's risk of developing RCC. Moreover, large-scale investigations of somatic alterations of the genomic and transcriptomic landscapes in tumours using next-generation sequencing technology have revealed new information on the molecular pathways that are characteristically disrupted in various RCC subtypes. Sequencing studies have revealed that epigenetic machinery and chromatin remodelling complexes are disrupted in >80% of clear cell RCC tumours, the most common form of the disease. The growing knowledge of subtype-specific molecular abnormalities arising from genomics has opened new avenues towards the development of molecular diagnostics for RCC subtypes, and for the rational design of therapeutic approaches tailored to patients based on the molecular profiles of their tumours. Genomic studies have also pinpointed a possible role of environmental exposure to aristolochic acid, a nephrotoxin, in the genesis of the disease in some regions of central Europe. In this Review, we discuss the impact of genomics in identifying the genes and environmental exposures involved in disease susceptibility, and in discovering the molecular pathways that are disrupted somatically in different RCC subtypes. Further, we explore the possibilities provided by this genomic knowledge in providing a precision medicine approach for diagnosing and treating RCC. PMID- 27694979 TI - The importance of total kidney volume in evaluating progression of polycystic kidney disease. AB - The rate at which autosomal dominant polycystic kidney disease (ADPKD) progresses to end-stage renal disease varies widely and is determined by genetic and non genetic factors. The ability to determine the prognosis of children and young adults with ADPKD is important for the effective life-long management of the disease and to enable the efficacy of emerging therapies to be determined. Total kidney volume (TKV) reflects the sum volume of hundreds of individual cysts with potentially devastating effects on renal function. The sequential measurement of TKV has been advanced as a dynamic biomarker of disease progression, yet doubt remains among nephrologists and regulatory agencies as to its usefulness. Here, we review the mechanisms that lead to an increase in TKV in ADPKD, and examine the evidence supporting the conclusion that TKV provides a metric of disease progression that can be used to assess the efficacy of potential therapeutic regimens in children and adults with ADPKD. Moreover, we propose that TKV can be used to monitor treatment efficacy in patients with normal levels of renal function, before the pathologic processes of ADPKD cause extensive fibrosis and irreversible loss of functioning renal tissue. PMID- 27694981 TI - The optical frequency comb fibre spectrometer. AB - Optical frequency comb sources provide thousands of precise and accurate optical lines in a single device enabling the broadband and high-speed detection required in many applications. A main challenge is to parallelize the detection over the widest possible band while bringing the resolution to the single comb-line level. Here we propose a solution based on the combination of a frequency comb source and a fibre spectrometer, exploiting all-fibre technology. Our system allows for simultaneous measurement of 500 isolated comb lines over a span of 0.12 THz in a single acquisition; arbitrarily larger span are demonstrated (3,500 comb lines over 0.85 THz) by doing sequential acquisitions. The potential for precision measurements is proved by spectroscopy of acetylene at 1.53 MUm. Being based on all-fibre technology, our system is inherently low-cost, lightweight and may lead to the development of a new class of broadband high-resolution spectrometers. PMID- 27694982 TI - Genome-wide association analysis identifies genetic loci associated with resistance to multiple antimalarials in Plasmodium falciparum from China-Myanmar border. AB - Drug resistance has emerged as one of the greatest challenges facing malaria control. The recent emergence of resistance to artemisinin (ART) and its partner drugs in ART-based combination therapies (ACT) is threatening the efficacy of this front-line regimen for treating Plasmodium falciparum parasites. Thus, an understanding of the molecular mechanisms that underlie the resistance to ART and the partner drugs has become a high priority for resistance containment and malaria management. Using genome-wide association studies, we investigated the associations of genome-wide single nucleotide polymorphisms with in vitro sensitivities to 10 commonly used antimalarial drugs in 94 P. falciparum isolates from the China-Myanmar border area, a region with the longest history of ART usage. We identified several loci associated with various drugs, including those containing pfcrt and pfdhfr. Of particular interest is a locus on chromosome 10 containing the autophagy-related protein 18 (ATG18) associated with decreased sensitivities to dihydroartemisinin, artemether and piperaquine - an ACT partner drug in this area. ATG18 is a phosphatidylinositol-3-phosphate binding protein essential for autophagy and recently identified as a potential ART target. Further investigations on the ATG18 and genes at the chromosome 10 locus may provide an important lead for a connection between ART resistance and autophagy. PMID- 27694983 TI - Disruption of phenylalanine hydroxylase reduces adult lifespan and fecundity, and impairs embryonic development in parthenogenetic pea aphids. AB - Phenylalanine hydroxylase (PAH) is a key tyrosine-biosynthetic enzyme involved in neurological and melanin-associated physiological processes. Despite extensive investigations in holometabolous insects, a PAH contribution to insect embryonic development has never been demonstrated. Here, we have characterized, for the first time, the PAH gene in a hemimetabolous insect, the aphid Acyrthosiphon pisum. Phylogenetic and sequence analyses confirmed that ApPAH is closely related to metazoan PAH, exhibiting the typical ACT regulatory and catalytic domains. Temporal expression patterns suggest that ApPAH has an important role in aphid developmental physiology, its mRNA levels peaking at the end of embryonic development. We used parental dsApPAH treatment to generate successful knockdown in aphid embryos and to study its developmental role. ApPAH inactivation shortens the adult aphid lifespan and considerably affects fecundity by diminishing the number of nymphs laid and impairing embryonic development, with newborn nymphs exhibiting severe morphological defects. Using single nymph HPLC analyses, we demonstrated a significant tyrosine deficiency and a consistent accumulation of the upstream tyrosine precursor, phenylalanine, in defective nymphs, thus confirming the RNAi-mediated disruption of PAH activity. This study provides first insights into the role of PAH in hemimetabolous insects and demonstrates that this metabolic gene is essential for insect embryonic development. PMID- 27694984 TI - Interplay between transglutaminases and heparan sulphate in progressive renal scarring. AB - Transglutaminase-2 (TG2) is a new anti-fibrotic target for chronic kidney disease, for its role in altering the extracellular homeostatic balance leading to excessive build-up of matrix in kidney. However, there is no confirmation that TG2 is the only transglutaminase involved, neither there are strategies to control its action specifically over that of the conserved family-members. In this study, we have profiled transglutaminase isozymes in the rat subtotal nephrectomy (SNx) model of progressive renal scarring. All transglutaminases increased post-SNx peaking at loss of renal function but TG2 was the predominant enzyme. Upon SNx, extracellular TG2 deposited in the tubulointerstitium and peri glomerulus via binding to heparan sulphate (HS) chains of proteoglycans and co associated with syndecan-4. Extracellular TG2 was sufficient to activate transforming growth factor-beta1 in tubular epithelial cells, and this process occurred in a HS-dependent way, in keeping with TG2-affinity for HS. Analysis of heparin binding of the main transglutaminases revealed that although the interaction between TG1 and HS is strong, the conformational heparin binding site of TG2 is not conserved, suggesting that TG2 has a unique interaction with HS within the family. Our data provides a rationale for a novel anti-fibrotic strategy specifically targeting the conformation-dependent TG2-epitope interacting with HS. PMID- 27694987 TI - Novel optical gyroscope: proof of principle demonstration and future scope. AB - We report the first proof-of-principle demonstration of the resonant optical gyroscope with reflector that we have recently proposed. The device is very different from traditional optical gyroscopes since it uses the inherent coupling between the clockwise and counterclockwise propagating waves to sense the rotation. Our demonstration confirms our theoretical analysis and simulations. We also demonstrate a novel method of biasing the gyroscope using orthogonal polarization states. The simplicity of the structure and the readout method, the theoretically predicted high sensitivities (better than 0.001 deg/hr), and the possibility of further performance enhancement using a related laser based active device, all have immense potential for attracting fresh research and technological initiatives. PMID- 27694985 TI - 3D bioprinting matrices with controlled pore structure and release function guide in vitro self-organization of sweat gland. AB - 3D bioprinting matrices are novel platforms for tissue regeneration. Tissue self organization is a critical process during regeneration that implies the features of organogenesis. However, it is not clear from the current evidences whether 3D printed construct plays a role in guiding tissue self-organization in vitro. Based on our previous study, we bioprinted a 3D matrix as the restrictive niche for direct sweat gland differentiation of epidermal progenitors by different pore structure (300-MUm or 400-MUm nozzle diameters printed) and reported a long-term gradual transition of differentiated cells into glandular morphogenesis occurs within the 3D construct in vitro. At the initial 14-day culture, an accelerated cell differentiation was achieved with inductive cues released along with gelatin reduction. After protein release completed, the 3D construct guide the self organized formation of sweat gland tissues, which is similar to that of the natural developmental process. However, glandular morphogenesis was only observed in 300-MUm-printed constructs. In the absence of 3D architectural support, glandular morphogenesis was not occurred. This striking finding made us to identify a previously unknown role of the 3D-printed structure in glandular tissue regeneration, and this self-organizing strategy can be applied to forming other tissues in vitro. PMID- 27694986 TI - Mapping light-driven conformational changes within the photosensory module of plant phytochrome B. AB - Organisms developed different photoreceptors to be able to adapt to changing environmental light conditions. Phytochromes are red/far-red (r/fr) photochromic photoreceptors that belong to the classical photoreceptors along with cryptochromes and phototropins. They convert absorbed light into a biological signal by switching between two states in a light-dependent manner therefore enabling the light control downstream signalling. Their Pfr conformation is the biological active form in plants, but until now only a structure of the ground state (Pr) was solved. Here, the authors provide information about structural changes occurring during photoconversion within phytochrome B and identify possible interaction sites for its N-terminal extension (NTE) utilising hydrogen/deuterium exchange rate analyses of its amide backbone. Especially, the newly identified light-dependency of two regions in the NTE are of particular interest for understanding the involvement of the phytochrome's NTE in the regulation of its downstream signalling. PMID- 27694989 TI - Biomimetic Nanofibrillation in Two-Component Biopolymer Blends with Structural Analogs to Spider Silk. AB - Despite the enormous potential in bioinspired fabrication of high-strength structure by mimicking the spinning process of spider silk, currently accessible routes (e.g., microfluidic and electrospinning approaches) still have substantial function gaps in providing precision control over the nanofibrillar superstructure, crystalline morphology or molecular orientation. Here the concept of biomimetic nanofibrillation, by copying the spiders' spinning principles, was conceived to build silk-mimicking hierarchies in two-phase biodegradable blends, strategically involving the stepwise integration of elongational shear and high pressure shear. Phase separation confined on nanoscale, together with deformation of discrete phases and pre-alignment of polymer chains, was triggered in the elongational shear, conferring the readiness for direct nanofibrillation in the latter shearing stage. The orderly aligned nanofibrils, featuring an ultralow diameter of around 100 nm and the "rigid-soft" system crosslinked by nanocrystal domains like silk protein dopes, were secreted by fine nanochannels. The incorporation of multiscale silk-mimicking structures afforded exceptional combination of strength, ductility and toughness for the nanofibrillar polymer composites. The proposed spider spinning-mimicking strategy, offering the biomimetic function integration unattainable with current approaches, may prompt materials scientists to pursue biopolymer mimics of silk with high performance yet light weight. PMID- 27694988 TI - Monosodium urate crystal-induced pro-interleukin-1beta production is post transcriptionally regulated via the p38 signaling pathway in human monocytes. AB - IL-1beta is a key mediator of sterile inflammation in response to endogenous particulates, a type of damage-associated molecular pattern (DAMPs) molecule derived from damaged cells. Despite the well-known role of sterile particulates such as monosodium urate (MSU) crystals as inflammasome inducers in monocytes/macrophages, little is known regarding how pro-IL-1beta synthesis is induced under sterile inflammatory conditions. We provide evidence that MSU crystals post-transcriptionally induce the rapid production of pro-IL-1beta in human primary monocytes. Metabolic labeling and pull-down assays for newly synthesized proteins clearly showed that MSU crystals rapidly, within 30 min, induce the synthesis of pro-IL-1beta as well as global proteins. Notably, MSU crystal-induced pro-IL-1beta synthesis is selectively dependent on the p38 MAPK pathway, whereas global protein synthesis is mediated via the mTOR, ERK1/2, and p38 pathways. Furthermore, inhibition of Mnk1, a substrate of p38, blocked MSU crystal-induced pro-IL-1beta synthesis downstream of eIF4E phosphorylation. In addition, the p38 MAPK pathway leading to phosphorylation of MK2 was also critical for stabilization of pro-IL-1beta mRNA following MSU stimulation. Our findings demonstrate that post-transcriptional regulation via p38 MAPK plays a central role in the rapid synthesis of pro-IL-1beta in response to MSU crystals, which is an essential step for IL-1beta production in human monocytes. PMID- 27694990 TI - History-dependent variability in population dynamics during evidence accumulation in cortex. AB - We studied how the posterior parietal cortex combines new information with ongoing activity dynamics as mice accumulate evidence during a virtual navigation task. Using new methods to analyze population activity on single trials, we found that activity transitioned rapidly between different sets of active neurons. Each event in a trial, whether an evidence cue or a behavioral choice, caused seconds long modifications to the probabilities that govern how one activity pattern transitions to the next, forming a short-term memory. A sequence of evidence cues triggered a chain of these modifications resulting in a signal for accumulated evidence. Multiple distinguishable activity patterns were possible for the same accumulated evidence because representations of ongoing events were influenced by previous within- and across-trial events. Therefore, evidence accumulation need not require the explicit competition between groups of neurons, as in winner-take all models, but could instead emerge implicitly from general dynamical properties that instantiate short-term memory. PMID- 27694992 TI - Computational principles of synaptic memory consolidation. AB - Memories are stored and retained through complex, coupled processes operating on multiple timescales. To understand the computational principles behind these intricate networks of interactions, we construct a broad class of synaptic models that efficiently harness biological complexity to preserve numerous memories by protecting them against the adverse effects of overwriting. The memory capacity scales almost linearly with the number of synapses, which is a substantial improvement over the square root scaling of previous models. This was achieved by combining multiple dynamical processes that initially store memories in fast variables and then progressively transfer them to slower variables. Notably, the interactions between fast and slow variables are bidirectional. The proposed models are robust to parameter perturbations and can explain several properties of biological memory, including delayed expression of synaptic modifications, metaplasticity, and spacing effects. PMID- 27694993 TI - Ultra-rare disruptive and damaging mutations influence educational attainment in the general population. AB - Disruptive, damaging ultra-rare variants in highly constrained genes are enriched in individuals with neurodevelopmental disorders. In the general population, this class of variants was associated with a decrease in years of education (YOE). This effect was stronger among highly brain-expressed genes and explained more YOE variance than pathogenic copy number variation but less than common variants. Disruptive, damaging ultra-rare variants in highly constrained genes influence the determinants of YOE in the general population. PMID- 27694996 TI - The origin of hyperferroelectricity in LiBO3 (B = V, Nb, Ta, Os). AB - The electronic and structural properties of LiBO3 (B = V, Nb, Ta, Os) are investigated via first-principles methods. We show that LiBO3 belong to the recently proposed hyperferroelectrics (hyperFEs), i.e., they all have unstable longitudinal optic phonon modes. Especially, the ferroelectric-like instability in the metal LiOsO3, whose optical dielectric constant goes to infinity, is a limiting case of hyperFEs. Via an effective Hamiltonian, we further show that, in contrast to normal proper ferroelectricity, in which the ferroelectric instability usually comes from long-range coulomb interactions, the hyperFE instability is due to the structure instability driven by short-range interactions. This could happen in systems with large ion size mismatches, which therefore provides a useful guidance in searching for novel hyperFEs. PMID- 27694994 TI - Increased burden of ultra-rare protein-altering variants among 4,877 individuals with schizophrenia. AB - By analyzing the exomes of 12,332 unrelated Swedish individuals, including 4,877 individuals affected with schizophrenia, in ways informed by exome sequences from 45,376 other individuals, we identified 244,246 coding-sequence and splice-site ultra-rare variants (URVs) that were unique to individual Swedes. We found that gene-disruptive and putatively protein-damaging URVs (but not synonymous URVs) were more abundant among individuals with schizophrenia than among controls (P = 1.3 * 10-10). This elevation of protein-compromising URVs was several times larger than an analogously elevated rate for de novo mutations, suggesting that most rare-variant effects on schizophrenia risk are inherited. Among individuals with schizophrenia, the elevated frequency of protein-compromising URVs was concentrated in brain-expressed genes, particularly in neuronally expressed genes; most of this elevation arose from large sets of genes whose RNAs have been found to interact with synaptically localized proteins. Our results suggest that synaptic dysfunction may mediate a large fraction of strong, individually rare genetic influences on schizophrenia risk. PMID- 27694995 TI - Chd8 mediates cortical neurogenesis via transcriptional regulation of cell cycle and Wnt signaling. AB - De novo mutations in CHD8 are strongly associated with autism spectrum disorder, but the basic biology of CHD8 remains poorly understood. Here we report that Chd8 knockdown during cortical development results in defective neural progenitor proliferation and differentiation that ultimately manifests in abnormal neuronal morphology and behaviors in adult mice. Transcriptome analysis revealed that while Chd8 stimulates the transcription of cell cycle genes, it also precludes the induction of neural-specific genes by regulating the expression of PRC2 complex components. Furthermore, knockdown of Chd8 disrupts the expression of key transducers of Wnt signaling, and enhancing Wnt signaling rescues the transcriptional and behavioral deficits caused by Chd8 knockdown. We propose that these roles of Chd8 and the dynamics of Chd8 expression during development help negotiate the fine balance between neural progenitor proliferation and differentiation. Together, these observations provide new insights into the neurodevelopmental role of Chd8.

AB - Severe burn injury significantly affects cardiovascular function for up to 3 years. However, whether this leads to long-term pathology is unknown. The impact of non-severe burn injury, which accounts for over 80% of admissions in developed countries, has not been investigated. Using a rodent model of non-severe burn injury with subsequent echocardiography we showed significantly increased left ventricular end systolic diameter (LVESD) and ventricular wall thickness at up to 3 months post-injury. Use of propranolol abrogated the changes in cardiac measures observed. Subsequently we investigated changes in a patient cohort with non-severe injury. Echocardiography measured at baseline and at 3 months post injury showed increased LVESD at 3 months and significantly decreased posterior wall diameter. Finally, 32 years of Western Australian hospital records were used to investigate the incidence of cardiovascular disease admissions after burn injury. People who had experienced a burn had increased hospital admissions and length of stay for cardiovascular diseases when compared to a matched uninjured cohort. This study presents animal, patient and population data that strongly suggest non-severe burn injury has significant effects on cardiovascular function and long-term morbidity in some burn patients. Identification of patients at risk will promote better intervention and outcomes for burn patients. PMID- 27694997 TI - A capillary electrophoresis coupled to mass spectrometry pipeline for long term comparable assessment of the urinary metabolome. AB - Although capillary electrophoresis coupled to mass spectrometry (CE-MS) has potential application in the field of metabolite profiling, very few studies actually used CE-MS to identify clinically useful body fluid metabolites. Here we present an optimized CE-MS setup and analysis pipeline to reproducibly explore the metabolite content of urine. We show that the use of a beveled tip capillary improves the sensitivity of detection over a flat tip. We also present a novel normalization procedure based on the use of endogenous stable urinary metabolites identified in the combined metabolome of 75 different urine samples from healthy and diseased individuals. This method allows a highly reproducible comparison of the same sample analyzed nearly 130 times over a range of 4 years. To demonstrate the use of this pipeline in clinical research we compared the urinary metabolome of 34 newborns with ureteropelvic junction (UPJ) obstruction and 15 healthy newborns. We identified 32 features with differential urinary abundance. Combination of the 32 compounds in a SVM classifier predicted with 76% sensitivity and 86% specificity UPJ obstruction in a separate validation cohort of 24 individuals. Thus, this study demonstrates the feasibility to use CE-MS as a tool for the identification of clinically relevant urinary metabolites. PMID- 27694998 TI - Glatiramer acetate treatment normalized the monocyte activation profile in MS patients to that of healthy controls. AB - Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system, and monocytes contribute to MS-associated neuroinflammation. While classically activated monocytes promote inflammation, type II-activated monocytes improve the course of MS. This study investigated type II activation of monocytes and their two main subsets, namely CD14+ (CD14++CD16- subset) and CD16+ monocytes (CD14+CD16+ subset), by glatiramer acetate (GA) or intravenous immunoglobulin associated immune complexes (IC), both of which are known MS treatments. Total monocytes and subsets were isolated from peripheral blood mononuclear cells (PBMC) of healthy controls, untreated MS patients (MS) and GA-treated MS patients (GA-MS). In contrast to the more activated ex vivo profile of monocytes from the MS group, monocytes from the GA-MS group resembled those from healthy controls. In vitro type II activation with GA primarily reduced CD40, CD86 and IL-12p40 whereas type II activation with IC consistently reduced CD40 but increased interleukin-10 (IL-10), suggesting that the GA and IC activation pathways are distinct. Moreover, while GA treatment reduced IL-12p40 by both CD14+ and CD16+ subsets, IC treatment only enhanced IL-10 by the CD16+ subset. Further analysis of the CD16+ subset revealed that MS patients had a greatly expanded CD14+CD16int population while both CD14+CD16int and CD14lowCD16high monocyte populations were expanded in GA-MS patients. Finally, a global analysis of the ex vivo monocyte data indicated that GA treatment distinctly altered the monocyte profile of MS patients, further supporting the idea that GA directly targets monocytes. PMID- 27695000 TI - Initial seeding of the embryonic thymus by immune-restricted lympho-myeloid progenitors. AB - The final stages of restriction to the T cell lineage occur in the thymus after the entry of thymus-seeding progenitors (TSPs). The identity and lineage potential of TSPs remains unclear. Because the first embryonic TSPs enter a non vascularized thymic rudiment, we were able to directly image and establish the functional and molecular properties of embryonic thymopoiesis-initiating progenitors (T-IPs) before their entry into the thymus and activation of Notch signaling. T-IPs did not include multipotent stem cells or molecular evidence of T cell-restricted progenitors. Instead, single-cell molecular and functional analysis demonstrated that most fetal T-IPs expressed genes of and had the potential to develop into lymphoid as well as myeloid components of the immune system. Moreover, studies of embryos deficient in the transcriptional regulator RBPJ demonstrated that canonical Notch signaling was not involved in pre-thymic restriction to the T cell lineage or the migration of T-IPs. PMID- 27695001 TI - Identification of a role for TRIM29 in the control of innate immunity in the respiratory tract. AB - The respiratory tract is heavily populated with innate immune cells, but the mechanisms that control such cells are poorly defined. Here we found that the E3 ubiquitin ligase TRIM29 was a selective regulator of the activation of alveolar macrophages, the expression of type I interferons and the production of proinflammatory cytokines in the lungs. We found that deletion of TRIM29 enhanced macrophage production of type I interferons and protected mice from infection with influenza virus, while challenge of Trim29-/- mice with Haemophilus influenzae resulted in lethal lung inflammation due to massive production of proinflammatory cytokines by macrophages. Mechanistically, we demonstrated that TRIM29 inhibited interferon-regulatory factors and signaling via the transcription factor NF-kappaB by degrading the adaptor NEMO and that TRIM29 directly bound NEMO and subsequently induced its ubiquitination and proteolytic degradation. These data identify TRIM29 as a key negative regulator of alveolar macrophages and might have important clinical implications for local immunity and immunopathology. PMID- 27695002 TI - Suppression by TFR cells leads to durable and selective inhibition of B cell effector function. AB - Follicular regulatory T cells (TFR cells) inhibit follicular helper T cell (TFH cell)-mediated antibody production. The mechanisms by which TFR cells exert their key immunoregulatory functions are largely unknown. Here we found that TFR cells induced a distinct suppressive state in TFH cells and B cells, in which effector transcriptional signatures were maintained but key effector molecules and metabolic pathways were suppressed. The suppression of B cell antibody production and metabolism by TFR cells was durable and persisted even in the absence of TFR cells. This durable suppression was due in part to epigenetic changes. The cytokine IL-21 was able to overcome TFR cell-mediated suppression and inhibited TFR cells and stimulated B cells. By determining mechanisms of TFR cell-mediated suppression, we have identified methods for modulating the function of TFR cells and antibody production. PMID- 27695004 TI - Time-resolved metabolomics analysis of individual differences during the early stage of lipopolysaccharide-treated rats. AB - Lipopolysaccharide (LPS) can lead to uncontrollable cytokine production and eventually cause fatal sepsis syndrome. Individual toxicity difference of LPS has been widely reported. In our study we observed that two thirds of the rats (24/36) died at a given dose of LPS, while the rest (12/36) survived. Tracking the dynamic metabolic change in survival and non-survival rats in the early stage may reveal new system information to understand the inter-individual variation in response to LPS. As the time-resolved datasets are very complex and no single method can elucidate the problem clearly and comprehensively, the static and dynamic metabolomics methods were employed in combination as cross-validation. Intriguingly, some common results have been observed. Lipids were the main different metabolites between survival and non-survival rats in pre-dose serum and in the early stage of infection with LPS. The LPS treatment led to S-adenosly methionine and total cysteine individual difference in early stage, and subsequent significant perturbations in energy metabolism and oxidative stress. Furthermore, cytokine profiles were analyzed to identify potential biological associations between cytokines and specific metabolites. Our collective findings may provide some heuristic guidance for elucidating the underlying mechanism of individual difference in LPS-mediated disease. PMID- 27695003 TI - Foxp3 and Toll-like receptor signaling balance Treg cell anabolic metabolism for suppression. AB - CD4+ effector T cells (Teff cells) and regulatory T cells (Treg cells) undergo metabolic reprogramming to support proliferation and immunological function. Although signaling via the lipid kinase PI(3)K (phosphatidylinositol-3-OH kinase), the serine-threonine kinase Akt and the metabolic checkpoint kinase complex mTORC1 induces both expression of the glucose transporter Glut1 and aerobic glycolysis for Teff cell proliferation and inflammatory function, the mechanisms that regulate Treg cell metabolism and function remain unclear. We found that Toll-like receptor (TLR) signals that promote Treg cell proliferation increased PI(3)K-Akt-mTORC1 signaling, glycolysis and expression of Glut1. However, TLR-induced mTORC1 signaling also impaired Treg cell suppressive capacity. Conversely, the transcription factor Foxp3 opposed PI(3)K-Akt-mTORC1 signaling to diminish glycolysis and anabolic metabolism while increasing oxidative and catabolic metabolism. Notably, Glut1 expression was sufficient to increase the number of Treg cells, but it reduced their suppressive capacity and Foxp3 expression. Thus, inflammatory signals and Foxp3 balance mTORC1 signaling and glucose metabolism to control the proliferation and suppressive function of Treg cells. PMID- 27695005 TI - Adsorptive Removal of Pharmaceuticals and Personal Care Products from Water with Functionalized Metal-organic Frameworks: Remarkable Adsorbents with Hydrogen bonding Abilities. AB - Adsorption of typical pharmaceuticals and personal care products (PPCPs) (such as naproxen, ibuprofen and oxybenzone) from aqueous solutions was studied by using the highly porous metal-organic framework (MOF) MIL-101 with and without functionalization. Adsorption results showed that MIL-101s with H-donor functional groups such as -OH and -NH2 were very effective for naproxen adsorption, despite a decrease in porosity, probably because of H-bonding between O atoms on naproxen and H atoms on the adsorbent. For this reason, MIL-101 with two functional groups capable of H-bonding (MIL-101-(OH)2) exhibited remarkable adsorption capacity based on adsorbent surface area. The favorable contributions of -OH and -(OH)2 on MIL-101 in the increased adsorption of ibuprofen and oxybenzone (especially based on porosity) confirmed again the importance of H bonding mechanism. The adsorbent with the highest adsorption capacity, MIL-101 OH, was very competitive when compared with carbonaceous materials, mesoporous materials, and pristine MIL-101. Moreover, the MIL-101-OH could be recycled several times by simply washing with ethanol, suggesting potential application in the adsorptive removal of PPCPs from water.

PMID- 27695006 TI - Discovery of Isoquinolinoquinazolinones as a Novel Class of Potent PPARgamma Antagonists with Anti-adipogenic Effects. AB - Conformational change in helix 12 can alter ligand-induced PPARgamma activity; based on this reason, isoquinolinoquinazolinones, structural homologs of berberine, were designed and synthesized as PPARgamma antagonists. Computational docking and mutational study indicated that isoquinolinoquinazolinones form hydrogen bonds with the Cys285 and Arg288 residues of PPARgamma. Furthermore, SPR results demonstrated strong binding affinity of isoquinolinoquinazolinones towards PPARgamma. Additionally, biological assays showed that this new series of PPARgamma antagonists more strongly inhibit adipocyte differentiation and PPARgamma2-induced transcriptional activity than GW9662.

AB - Intracranial volume reflects the maximally attained brain size during development, and remains stable with loss of tissue in late life. It is highly heritable, but the underlying genes remain largely undetermined. In a genome-wide association study of 32,438 adults, we discovered five previously unknown loci for intracranial volume and confirmed two known signals. Four of the loci were also associated with adult human stature, but these remained associated with intracranial volume after adjusting for height. We found a high genetic correlation with child head circumference (rhogenetic = 0.748), which indicates a similar genetic background and allowed us to identify four additional loci through meta-analysis (Ncombined = 37,345). Variants for intracranial volume were also related to childhood and adult cognitive function, and Parkinson's disease, and were enriched near genes involved in growth pathways, including PI3K-AKT signaling. These findings identify the biological underpinnings of intracranial volume and their link to physiological and pathological traits.

PMID- 27695030 TI - Phosphorylation of Staphylococcus aureus Protein-Tyrosine Kinase Affects the Function of Glucokinase and Biofilm Formation. AB - BACKGROUND: When Staphylococcus aureus is grown in the presence of high concentration of external glucose, this sugar is phosphorylated by glucokinase (glkA) to form glucose-6-phosphate. This product subsequently enters into anabolic phase, which favors biofilm formation. The presence of ROK (repressor protein, open reading frame, sugar kinase) motif, phosphate-1 and -2 sites, and tyrosine kinase sites in glkA of S. aureus indicates that phosphorylation must regulate the glkA activity. The aim of the present study was to identify the effect of phosphorylation on the function of S. aureus glkA and biofilm formation. METHODS: Pure glkA and protein-tyrosine kinase (BYK) of S. aureus ATCC 12600 were obtained by fractionating the cytosolic fractions of glkA1 and BYK-1 expressing recombinant clones through nickel metal chelate column. The pure glkA was used as a substrate for BYK and the phosphorylation of glkA was confirmed by treating with reagent A and resolving in SDS-PAGE, as well as staining with reagent A. The kinetic parameters of glkA and phosphorylated glkA were determined spectrophotometrically, and in silico tools were used for validation. S. aureus was grown in brain heart infusion broth, which was supplemented with glucose, and then biofilm units were calculated. RESULTS: Fourfold elevated glkA activity was observed upon the phosphorylation by BYK. Protein-protein docking analysis revealed that glkA structure docked close to the adenosine triphosphate-binding site of BYK structure corroborating the kinetic results. Further, S. aureus grown in the presence of elevated glucose concentration exhibited an increase in the rate of biofilm formation. CONCLUSION: The elevated function of glkA is an essential requirement for increased biofilm units in S. aureus, a key pathogenic factor that helps its survival and spread the infection. PMID- 27695033 TI - An Empirical Biomarker-Based Calculator for Cystic Index in a Model of Autosomal Recessive Polycystic Kidney Disease-The Nieto-Narayan Formula. AB - Autosomal recessive polycystic kidney disease (ARPKD) is associated with progressive enlargement of the kidneys fuelled by the formation and expansion of fluid-filled cysts. The disease is congenital and children that do not succumb to it during the neonatal period will, by age 10 years, more often than not, require nephrectomy+renal replacement therapy for management of both pain and renal insufficiency. Since increasing cystic index (CI; percent of kidney occupied by cysts) drives both renal expansion and organ dysfunction, management of these patients, including decisions such as elective nephrectomy and prioritization on the transplant waitlist, could clearly benefit from serial determination of CI. So also, clinical trials in ARPKD evaluating the efficacy of novel drug candidates could benefit from serial determination of CI. Although ultrasound is currently the imaging modality of choice for diagnosis of ARPKD, its utilization for assessing disease progression is highly limited. Magnetic resonance imaging or computed tomography, although more reliable for determination of CI, are expensive, time-consuming and somewhat impractical in the pediatric population. Using a well-established mammalian model of ARPKD, we undertook a big data-like analysis of minimally- or non-invasive blood and urine biomarkers of renal injury/dysfunction to derive a family of equations for estimating CI. We then applied a signal averaging protocol to distill these equations to a single empirical formula for calculation of CI. Such a formula will eventually find use in identifying and monitoring patients at high risk for progressing to end-stage renal disease and aid in the conduct of clinical trials. PMID- 27695032 TI - Genomic and Evolutionary Analysis of Two Salmonella enterica Serovar Kentucky Sequence Types Isolated from Bovine and Poultry Sources in North America. AB - Salmonella enterica subsp. enterica serovar Kentucky is frequently isolated from healthy poultry and dairy cows and is occasionally isolated from people with clinical disease. A genomic analysis of 119 isolates collected in the United States from dairy cows, ground beef, poultry and poultry products, and human clinical cases was conducted. Results of the analysis demonstrated that the majority of poultry and bovine-associated S. Kentucky were sequence type (ST) 152. Several bovine-associated (n = 3) and food product isolates (n = 3) collected from the United States and the majority of human clinical isolates were ST198, a sequence type that is frequently isolated from poultry and occasionally from human clinical cases in Northern Africa, Europe and Southeast Asia. A phylogenetic analysis indicated that both STs are more closely related to other Salmonella serovars than they are to each other. Additionally, there was strong evidence of an evolutionary divergence between the poultry-associated and bovine associated ST152 isolates that was due to polymorphisms in four core genome genes. The ST198 isolates recovered from dairy farms in the United States were phylogenetically distinct from those collected from human clinical cases with 66 core genome SNPs differentiating the two groups, but more isolates are needed to determine the significance of this distinction. Identification of S. Kentucky ST198 from dairy animals in the United States suggests that the presence of this pathogen should be monitored in food-producing animals. PMID- 27695031 TI - Metal Chelation as a Powerful Strategy to Probe Cellular Circuitry Governing Fungal Drug Resistance and Morphogenesis. AB - Fungal pathogens have evolved diverse strategies to sense host-relevant cues and coordinate cellular responses, which enable virulence and drug resistance. Defining circuitry controlling these traits opens new opportunities for chemical diversity in therapeutics, as the cognate inhibitors are rarely explored by conventional screening approaches. This has great potential to address the pressing need for new therapeutic strategies for invasive fungal infections, which have a staggering impact on human health. To explore this approach, we focused on a leading human fungal pathogen, Candida albicans, and screened 1,280 pharmacologically active compounds to identify those that potentiate the activity of echinocandins, which are front-line therapeutics that target fungal cell wall synthesis. We identified 19 compounds that enhance activity of the echinocandin caspofungin against an echinocandin-resistant clinical isolate, with the broad spectrum chelator DTPA demonstrating the greatest synergistic activity. We found that DTPA increases susceptibility to echinocandins via chelation of magnesium. Whole genome sequencing of mutants resistant to the combination of DTPA and caspofungin identified mutations in the histidine kinase gene NIK1 that confer resistance to the combination. Functional analyses demonstrated that DTPA activates the mitogen-activated protein kinase Hog1, and that NIK1 mutations block Hog1 activation in response to both caspofungin and DTPA. The combination has therapeutic relevance as DTPA enhanced the efficacy of caspofungin in a mouse model of echinocandin-resistant candidiasis. We found that DTPA not only reduces drug resistance but also modulates morphogenesis, a key virulence trait that is normally regulated by environmental cues. DTPA induced filamentation via depletion of zinc, in a manner that is contingent upon Ras1-PKA signaling, as well as the transcription factors Brg1 and Rob1. Thus, we establish a new mechanism by which metal chelation modulates morphogenetic circuitry and echinocandin resistance, and illuminate a novel facet to metal homeostasis at the host-pathogen interface, with broad therapeutic potential. PMID- 27695034 TI - Xenobiotic Metabolism and Gut Microbiomes. AB - Humans are exposed to numerous xenobiotics, a majority of which are in the form of pharmaceuticals. Apart from human enzymes, recent studies have indicated the role of the gut bacterial community (microbiome) in metabolizing xenobiotics. However, little is known about the contribution of the plethora of gut microbiome in xenobiotic metabolism. The present study reports the results of analyses on xenobiotic metabolizing enzymes in various human gut microbiomes. A total of 397 available gut metagenomes from individuals of varying age groups from 8 nationalities were analyzed. Based on the diversities and abundances of the xenobiotic metabolizing enzymes, various bacterial taxa were classified into three groups, namely, least versatile, intermediately versatile and highly versatile xenobiotic metabolizers. Most interestingly, specific relationships were observed between the overall drug consumption profile and the abundance and diversity of the xenobiotic metabolizing repertoire in various geographies. The obtained differential abundance patterns of xenobiotic metabolizing enzymes and bacterial genera harboring them, suggest their links to pharmacokinetic variations among individuals. Additional analyses of a few well studied classes of drug modifying enzymes (DMEs) also indicate geographic as well as age specific trends. PMID- 27695035 TI - Diversity Takes Shape: Understanding the Mechanistic and Adaptive Basis of Bacterial Morphology. AB - The modern age of metagenomics has delivered unprecedented volumes of data describing the genetic and metabolic diversity of bacterial communities, but it has failed to provide information about coincident cellular morphologies. Much like metabolic and biosynthetic capabilities, morphology comprises a critical component of bacterial fitness, molded by natural selection into the many elaborate shapes observed across the bacterial domain. In this essay, we discuss the diversity of bacterial morphology and its implications for understanding both the mechanistic and the adaptive basis of morphogenesis. We consider how best to leverage genomic data and recent experimental developments in order to advance our understanding of bacterial shape and its functional importance. PMID- 27695036 TI - Differential Effects of Dietary Fat Content and Protein Source on Bone Phenotype and Fatty Acid Oxidation in Female C57Bl/6 Mice. AB - BACKGROUND: Glycomacropeptide (GMP) is a 64-amino acid glycophosphopeptide released from kappa-casein during cheesemaking that promotes satiety, reduces body fat, increases bone mass and infers prebiotic and anti-inflammatory effects. The impact of adiposity and gender on bone health is unclear. OBJECTIVE: To determine how feeding female mice diets providing 60% Fat Kcal (high-fat) or 13% Fat Kcal (control) with either GMP or casein as the protein source impacts: body composition, ex vivo fatty acid oxidation, bone (femoral) biomechanical performance, and the relationship between body composition and bone. METHODS: Weanling female C57Bl/6 mice were fed high-fat (60% Fat Kcal) or control diets (13% Fat Kcal) with GMP or casein from 3 to 32 weeks of age with assessment of body weight and food intake. Body composition was assessed by dual-energy X-ray absorptiometry (DXA). Fatty acid oxidation was measured in liver, muscle, and fat tissues using 14C-palmitate. Plasma concentrations of hormones and cytokines were determined. Bone biomechanical performance was assessed by the 3-point bending test. RESULTS: Female mice fed high-fat diets showed increased fatty acid oxidation capacity in both gastrocnemius muscle and brown adipose tissue compared to mice fed the control diets with a lower fat content. Despite increased fat mass in mice fed the high-fat diets, there was little evidence of glucose impairment or inflammation. Mice fed the high-fat diets had significantly greater total body bone mineral density (BMD), femoral BMD, and femoral cross-sectional area than mice fed the control diets. Femora of mice fed the high-fat diets had increased yield load and maximum load before fracture, consistent with greater bone strength, but reduced post-yield displacement or ductility, consistent with bone brittleness. Female mice fed a high-fat GMP diet displayed increased fat oxidation capacity in subcutaneous fat relative to mice fed the high-fat casein diet. Regardless of dietary fat content, GMP increased total body bone mineral content and femur length. The prebiotic properties of GMP may mediate the beneficial effects of GMP on bone. CONCLUSIONS: Female mice adapt to high-fat feeding by increasing oxidative capacity in muscle tissue and to a lesser extent brown adipose tissue. High-fat feeding in female mice leads to development of a bone phenotype where femora show increased BMD and are stronger, yet more brittle. The increased brittleness of bone was associated with increased body fat content due to high-fat feeding. In summary, high-fat feeding in female mice increases mineralization of bone, but negatively impacts bone quality resulting in brittle bones. PMID- 27695038 TI - Comparison of Confocal and Super-Resolution Reflectance Imaging of Metal Oxide Nanoparticles. AB - The potential for human exposure to manufactured nanoparticles (NPs) has increased in recent years, in part through the incorporation of engineered particles into a wide range of commercial goods and medical applications. NP are ideal candidates for use as therapeutic and diagnostic tools within biomedicine, however concern exists regarding their efficacy and safety. Thus, developing techniques for the investigation of NP uptake into cells is critically important. Current intracellular NP investigations rely on the use of either Transmission Electron Microscopy (TEM), which provides ultrahigh resolution, but involves cumbersome sample preparation rendering the technique incompatible with live cell imaging, or fluorescent labelling, which suffers from photobleaching, poor bioconjugation and, often, alteration of NP surface properties. Reflected light imaging provides an alternative non-destructive label free technique well suited, but not limited to, the visualisation of NP uptake within model systems, such as cells. Confocal reflectance microscopy provides optical sectioning and live imaging capabilities, with little sample preparation. However confocal microscopy is diffraction limited, thus the X-Y resolution is restricted to ~250 nm, substantially larger than the <100 nm size of NPs. Techniques such as super resolution light microscopy overcome this fundamental limitation, providing increased X-Y resolution. The use of Reflectance SIM (R-SIM) for NP imaging has previously only been demonstrated on custom built microscopes, restricting the widespread use and limiting NP investigations. This paper demonstrates the use of a commercial SIM microscope for the acquisition of super-resolution reflectance data with X-Y resolution of 115 nm, a greater than two-fold increase compared to that attainable with RCM. This increase in resolution is advantageous for visualising small closely spaced structures, such as NP clusters, previously unresolvable by RCM. This is advantageous when investigating the subcellular trafficking of NP within fluorescently labelled cellular compartments. NP signal can be observed using RCM, R-SIM and TEM and a direct comparison is presented. Each of these techniques has its own benefits and limitations; RCM and R-SIM provide novel complementary information while the combination of modalities provides a unique opportunity to gain additional information regarding NP uptake. The use of multiple imaging methods therefore greatly enhances the range of NPs that can be studied under label-free conditions. PMID- 27695037 TI - Comparative Transcriptome Analysis Reveals that a Ubiquitin-Mediated Proteolysis Pathway Is Important for Primary and Secondary Hair Follicle Development in Cashmere Goats. AB - BACKGROUND: The fleece of cashmere goats contains two distinct populations of fibers, a short and fine non-medullated insulating cashmere fiber and a long and coarse medullated guard hair. The former is produced by secondary follicles (SFs) and the later by primary follicles (PFs). Evidence suggests that the induction of PFs and SFs may require different signaling pathways. The regulation of BMP2/4 signaling by noggin and Edar signaling via Downless genes are essential for the induction of SFs and PFs, respectively. However, these differently expressed genes of the signaling pathway cannot directly distinguish between the PFs and SFs. RESULTS: In this study, we selected RNA samples from 11 PFs and 7 SFs that included 145,525 exons. The pathway analysis of 4512 differentially expressed exons revealed that the most statistically significant metabolic pathway was related to the ubiquitin-mediated proteolysis pathway (UMPP) (P<3.32x 10-7). In addition, the 51 exons of the UMPP that were differentially expressed between the different types of hair follicle (HFs) were compared by cluster analysis. This resulted in the PFs and SFs being divided into two classes. The expression level of two selected exons was analyzed by qRT-PCR, and the results indicated that the expression patterns were consistent with the deep sequencing results obtained by RNA-Seq. CONCLUSIONS: Based on the comparative transcriptome analysis of 18 HFs from cashmere goats, a large number of differentially expressed exons were identified using a high-throughput sequencing approach. This study suggests that UMPP activation is a prominent signaling pathway for distinguishing the PFs and SFs of cashmere goats. It is also a meaningful contribution to the theoretical basis of the biological study of the HFs of cashmere goats and other mammals.

AB - The wingless pathway has a powerful influence on bone metabolism and is a therapeutic target in skeletal disorders. Wingless signaling is mediated in part through the Frizzled (FZD) receptor family. FZD transcriptional regulation is poorly understood. Herein we tested the hypothesis that Sp1 plays an important role in the transcriptional regulation of FZD1 expression in osteoblasts and osteoblast mineralization. To test this hypothesis, we conducted FZD1 promoter assays in Saos2 cells with and without Sp1 overexpression. We found that Sp1 significantly up-regulates FZD1 promoter activity in Saos2 cells. Chromatin immunoprecipitation (ChIP) and electrophoretic mobility shift (EMSA) assays identified a novel and functional Sp1 binding site at -44 to -40 from the translation start site in the FZD1 promoter. The Sp1-dependent activation of the FZD1 promoter was abolished by mithramycin A (MMA), an antibiotic affecting both Sp1 binding and Sp1 protein levels in Saos2 cells. Similarly, down-regulation of Sp1 in hFOB cells resulted in less FZD1 expression and lower alkaline phosphatase activity. Moreover, over-expression of Sp1 increased FZD1 expression and Saos2 cell mineralization while MMA decreased Sp1 and FZD1 expression and Saos2 cell mineralization. Knockdown of FZD1 prior to Sp1 overexpression partially abolished Sp1 stimulation of osteoblast differentiation markers. Taken together, our results suggest that Sp1 plays a role in human osteoblast differentiation and mineralization, which is at least partially mediated by Sp1-dependent transactivation of FZD1.

AB - PURPOSE: This study examined diet-related problems and needs associated with nutritional care according to survival stage in Korean female cancer survivors. METHODS: 186 outpatients (breast or gynecologic cancer survivors) recruited. Subjects were classified as (1) extended stage (ES, 2-5 years from diagnosis) and (2) long-term stage (LS, >=5 years from diagnosis). Eating habits, changes in health related factors, nutritional needs, and quality of life were investigated. RESULTS: 43% of ES survivors had diet-related problems (p = .031); ES group reported dyspepsia and LS group reported anorexia/nausea as the major problem. Half of ES survivors had taste change, decreasing amount of intake, and reduced quality of life (p < .05). The LS group had a greater preference for sweet tastes than the ES group. According to their diagnosis, ES survivors with breast cancer gained weight (27.1%), whereas ES survivors with gynecologic cancer lost their body weight (34.5%) significantly. LS breast cancer patients showed great food preference for vegetables, whereas those with gynecologic cancer showed an increased preference for fish, meat and grain. Approximately 90% of survivors demanded nutritional care regarding restricted foods, preventing recurrence, particularly in ES survivors (p < .01). Moreover, main factors for nutritional care needs were body weight control for breast cancer and food environment for gynecologic cancer. CONCLUSION: Survivors have different aspects of diet-related problems by survival stage as dyspepsia in ES and anorexia in LS. ES stage had changes in dietary patterns and their food consumption have decreased. Most of survivors have demanded nutritional care regardless of survival stage. These features of each stage should be considered to improve their health. PMID- 27695040 TI - The Paradoxical Signals of Two TrkC Receptor Isoforms Supports a Rationale for Novel Therapeutic Strategies in ALS. AB - Full length TrkC (TrkC-FL) is a receptor tyrosine kinase whose mRNA can be spliced to a truncated TrkC.T1 isoform lacking the kinase domain. Neurotrophin-3 (NT-3) activates TrkC-FL to maintain motor neuron health and function and TrkC.T1 to produce neurotoxic TNF-alpha; hence resulting in opposing pathways. In mouse and human ALS spinal cord, the reduction of miR-128 that destabilizes TrkC.T1 mRNA results in up-regulated TrkC.T1 and TNF-alpha in astrocytes. We exploited conformational differences to develop an agonistic mAb 2B7 that selectively activates TrkC-FL, to circumvent TrkC.T1 activation. In mouse ALS, 2B7 activates spinal cord TrkC-FL signals, improves spinal cord motor neuron phenotype and function, and significantly prolongs life-span. Our results elucidate biological paradoxes of receptor isoforms and their role in disease progression, validate the concept of selectively targeting conformational epitopes in naturally occurring isoforms, and may guide the development of pro-neuroprotective (TrkC FL) and anti-neurotoxic (TrkC.T1) therapeutic strategies. PMID- 27695042 TI - Subjective Wellbeing, Objective Wellbeing and Inequality in Australia. AB - In recent years policy makers and social scientists have devoted considerable attention to wellbeing, a concept that refers to people's capacity to live healthy, creative and fulfilling lives. Two conceptual approaches dominate wellbeing research. The objective approach examines the objective components of a good life. The subjective approach examines people's subjective evaluations of their lives. In the objective approach how subjective wellbeing relates to objective wellbeing is not a relevant research question. The subjective approach does investigate how objective wellbeing relates to subjective wellbeing, but has focused primarily on one objective wellbeing indicator, income, rather than the comprehensive indicator set implied by the objective approach. This paper attempts to contribute by examining relationships between a comprehensive set of objective wellbeing measures and subjective wellbeing, and by linking wellbeing research to inequality research by also investigating how subjective and objective wellbeing relate to class, gender, age and ethnicity. We use three waves of a representative state-level household panel study from Queensland, Australia, undertaken from 2008 to 2010, to investigate how objective measures of wellbeing are socially distributed by gender, class, age, and ethnicity. We also examine relationships between objective wellbeing and overall life satisfaction, providing one of the first longitudinal analyses linking objective wellbeing with subjective evaluations. Objective aspects of wellbeing are unequally distributed by gender, age, class and ethnicity and are strongly associated with life satisfaction. Moreover, associations between gender, ethnicity, class and life satisfaction persist after controlling for objective wellbeing, suggesting that mechanisms in addition to objective wellbeing link structural dimensions of inequality to life satisfaction. PMID- 27695043 TI - Hydrodynamics of a Flexible Soft-Rayed Caudal Fin. AB - The paper addresses hydrodynamic performance of a slender swimmer furnished with a flexible small-aspect-ratio soft-rayed caudal fin. The recoil of the fin is found by solving the coupled hydro-elastic problem, in which the structure of the fin is modeled by a cantilever of variable cross section and the hydrodynamic forces acting on it are modeled using the elongated body theory. It is shown that the recoil has practically no effect on the propulsion efficiency of anguilliform swimmers, but has a profound effect on the efficiency of carangiform swimmers, which can increase almost four-fold between low-speed (low-thrust) cruise and high-speed (high-thrust) burst. Whilst the magnitude of this effect furnishes a plausible argument in favor of burst-and-coast locomotion strategies, it also infers that carangiform swimmers cannot rely on elastic recoil of the caudal fin to be efficient throughout the usable speed range, and must actively flex it at low speeds. PMID- 27695044 TI - Manual Loading Distribution During Carrying Behaviors: Implications for the Evolution of the Hominin Hand. AB - The human hand is unparalleled amongst primates in its ability to manipulate objects forcefully and dexterously. Previous research has predominantly sought to explain the evolution of these capabilities through an adaptive relationship between more modern human-like anatomical features in the upper limb and increased stone tool production and use proficiency. To date, however, we know little about the influence that other manipulatively demanding behaviors may have had upon the evolution of the human hand. The present study addresses one aspect of this deficiency by examining the recruitment of the distal phalanges during a range of manual transportation (i.e., carrying) events related to hominin behavioral repertoires during the Plio-Pleistocene. Specifically, forces on the volar pad of each digit are recorded during the transportation of stones and wooden branches that vary in weight and size. Results indicate that in most instances, the index and middle fingers are recruited to a significantly greater extent than the other three digits during carrying events. Relative force differences between digits were, however, dependent upon the size and weight of the object transported. Carrying behaviors therefore appear unlikely to have contributed to the evolution of the robust thumb anatomy observed in the human hand. Rather, results suggest that the manual transportation of objects may plausibly have influenced the evolution of the human gripping capabilities and the 3rd metacarpal styloid process. PMID- 27695045 TI - Tumor Specific Epigenetic Silencing of Corticotropin Releasing Hormone -Binding Protein in Renal Cell Carcinoma: Association of Hypermethylation and Metastasis. AB - The relevance of Corticotropin Releasing Hormone (CRH)-system in human malignancies is a question of growing interest. Here we investigated hypermethylation and epigenetic silencing of the CRH-Binding Protein (CRHBP) gene in clear cell renal cell cancer (ccRCC). Relative methylation of the CRHBP CpG island (CGI) was determined in 17 tumor cell lines as well as 86 ccRCC samples and 66 paired normal tissues using pyrosequencing and quantitative methylation specific PCR of bisulfite converted DNA. Results were statistically compared with relative mRNA expression levels of CRHBP and clinicopathological parameters of patients. Re-expression of CRHBP following 5-aza-2'-deoxycytidine treatment was investigated by quantitative mRNA expression analysis. Real-time impedance analysis was applied for analysis of invasiveness of renal tumor cells following si-RNA knockdown of CRHBP expression or ectopic expression of CRHBP. We found the CRHBP CGI to be frequently methylated in tumor cell lines of renal, prostatic, and bladder cancer. Comparison of methylation in normal and paired renal cancer tissue specimens revealed hypermethylation of the CRHBP CGI in tumors (p<1*10 12). DNA methylation and decreased mRNA expression were correlated (R = 0.83, p<1*10-12). Tumor cell lines showed 5-aza-2'-deoxycytidine dependent reduction of methylation and re-expression of CRHBP was associated with altered cellular invasiveness of renal cancer cells in real-time impedance invasion assays. Hypermethylation and inverse relationship with mRNA expression were validated in silico using the TCGA network data. We describe for the first time tumor specific epigenetic silencing of CRHBP and statistical association with aggressive tumors thus suggesting the CRH system to contribute to the development of kidney cancer. PMID- 27695046 TI - Role of Dicer1-Dependent Factors in the Paracrine Regulation of Epididymal Gene Expression. AB - Dicer1 is an endoribonuclease involved in the biogenesis of functional molecules such as microRNAs (miRNAs) and endogenous small interfering RNAs (endo-siRNAs). These small non-coding RNAs are important regulators of post-transcriptional gene expression and participate in the control of male fertility. With the knowledge that 1) Dicer1-dependent factors are required for proper sperm maturation in the epididymis, and that 2) miRNAs are potent mediators of intercellular communication in most biological systems, we investigated the role of Dicer1 dependent factors produced by the proximal epididymis (initial segment/caput)- including miRNAs- on the regulation of epididymal gene expression in the distal epididymis regions (i.e. corpus and cauda). To this end, we performed comparative microarray and ANOVA analyses on control vs. Defb41iCre/wt;Dicer1fl/fl mice in which functional Dicer1 is absent from the principal cells of the proximal epididymis. We identified 35 and 33 transcripts that displayed significant expression level changes in the corpus and cauda regions (Fold change > 2 or < 2; p < 0.002), respectively. Among these transcripts, Zn-alpha 2-glycoprotein (Azgp1) encodes for a sperm equatorial protein whose expression in the epididymis of Dicer1 cKO mice is significantly increased compared to controls. In addition, 154 miRNAs, including miR-210, miR-672, miR-191 and miR-204, showed significantly impaired biogenesis in the absence of Dicer1 from the principal cells of the proximal epididymis (Fold change > 2 or < -2; p < 0.01). These miRNAs are secreted via extracellular vesicles (EVs) derived from the DC2 epididymal principal cell line, and their expression correlates with target transcripts involved in distinct biological pathways, as evidenced by in silico analysis. Albeit correlative and based on in silico approach, our study proposes that Dicer1-dependent factors trigger- directly or not-significant genes expression changes in distinct regions of this organ. The paracrine control of functions important to post-testicular sperm maturation by Dicer1-dependent factors may open new avenues for the identification of molecular targets important to male fertility control. PMID- 27695047 TI - Contrasting Regulation of NO and ROS in Potato Defense-Associated Metabolism in Response to Pathogens of Different Lifestyles. AB - Our research provides new insights into how the low and steady-state levels of nitric oxide (NO) and reactive oxygen species (ROS) in potato leaves are altered after the challenge with the hemibiotroph Phytophthora infestans or the necrotroph Botrytis cinerea, with the subsequent rapid and invader-dependent modification of defense responses with opposite effects. Mainly in the avirulent (avr) P. infestans-potato system, NO well balanced with the superoxide level was tuned with a battery of SA-dependent defense genes, leading to the establishment of the hypersensitive response (HR) successfully arresting the pathogen. Relatively high levels of S-nitrosoglutathione and S-nitrosothiols concentrated in the main vein of potato leaves indicated the mobile function of these compounds as a reservoir of NO bioactivity. In contrast, low-level production of NO and ROS during virulent (vr) P. infestans-potato interactions might be crucial in the delayed up-regulation of PR-1 and PR-3 genes and compromised resistance to the hemibiotrophic pathogen. In turn, B. cinerea triggered huge NO overproduction and governed inhibition of superoxide production by blunting NADPH oxidase. Nevertheless, a relatively high level of H2O2 was found owing to the germin-like activity in cooperation with NO-mediated HR-like cell death in potato genotypes favorable to the necrotrophic pathogen. Moreover, B. cinerea not only provoked cell death, but also modulated the host redox milieu by boosting protein nitration, which attenuated SA production but not SA-dependent defense gene expression. Finally, based on obtained data the organismal cost of having machinery for HR in plant resistance to biotrophs is also discussed, while emphasizing new efforts to identify other components of the NO/ROS cell death pathway and improve plant protection against pathogens of different lifestyles. PMID- 27695049 TI - Where Is Current Research on Blockchain Technology?-A Systematic Review. AB - Blockchain is a decentralized transaction and data management technology developed first for Bitcoin cryptocurrency. The interest in Blockchain technology has been increasing since the idea was coined in 2008. The reason for the interest in Blockchain is its central attributes that provide security, anonymity and data integrity without any third party organization in control of the transactions, and therefore it creates interesting research areas, especially from the perspective of technical challenges and limitations. In this research, we have conducted a systematic mapping study with the goal of collecting all relevant research on Blockchain technology. Our objective is to understand the current research topics, challenges and future directions regarding Blockchain technology from the technical perspective. We have extracted 41 primary papers from scientific databases. The results show that focus in over 80% of the papers is on Bitcoin system and less than 20% deals with other Blockchain applications including e.g. smart contracts and licensing. The majority of research is focusing on revealing and improving limitations of Blockchain from privacy and security perspectives, but many of the proposed solutions lack concrete evaluation on their effectiveness. Many other Blockchain scalability related challenges including throughput and latency have been left unstudied. On the basis of this study, recommendations on future research directions are provided for researchers. PMID- 27695048 TI - Vietnam, a Hotspot for Chromosomal Diversity and Cryptic Species in Black Flies (Diptera: Simuliidae). AB - The increasing attention on Vietnam as a biodiversity hotspot prompted an investigation of the potential for cryptic diversity in black flies, a group well known elsewhere for its high frequency of isomorphic species. We analyzed the banding structure of the larval polytene chromosomes in the Simulium tuberosum species group to probe for diversity beyond the morphological level. Among 272 larvae, 88 different chromosomal rearrangements, primarily paracentric inversions, were discovered in addition to 25 already known in the basic sequences of the group in Asia. Chromosomal diversity in Vietnam far exceeds that known for the group in Thailand, with only about 5% of the rearrangements shared between the two countries. Fifteen cytoforms and nine morphoforms were revealed among six nominal species in Vietnam. Chromosomal evidence, combined with available molecular and morphological evidence, conservatively suggests that at least five of the cytoforms are valid species, two of which require formal names. The total chromosomal rearrangements and species (15) now known from the group in Vietnam far exceed those of any other area of comparable size in the world, supporting the country's status as a biodiversity hotspot. Phylogenetic inference based on uniquely shared, derived chromosomal rearrangements supports the clustering of cytoforms into two primary lineages, the Simulium tani complex and the Southeast Asian Simulium tuberosum subgroup. Some of these taxa could be threatened by habitat destruction, given their restricted geographical distributions and the expanding human population of Vietnam. PMID- 27695050 TI - Graphlet Based Metrics for the Comparison of Gene Regulatory Networks. AB - Understanding the control of gene expression remains one of the main challenges in the post-genomic era. Accordingly, a plethora of methods exists to identify variations in gene expression levels. These variations underlay almost all relevant biological phenomena, including disease and adaptation to environmental conditions. However, computational tools to identify how regulation changes are scarce. Regulation of gene expression is usually depicted in the form of a gene regulatory network (GRN). Structural changes in a GRN over time and conditions represent variations in the regulation of gene expression. Like other biological networks, GRNs are composed of basic building blocks called graphlets. As a consequence, two new metrics based on graphlets are proposed in this work: REConstruction Rate (REC) and REC Graphlet Degree (RGD). REC determines the rate of graphlet similarity between different states of a network and RGD identifies the subset of nodes with the highest topological variation. In other words, RGD discerns how th GRN was rewired. REC and RGD were used to compare the local structure of nodes in condition-specific GRNs obtained from gene expression data of Escherichia coli, forming biofilms and cultured in suspension. According to our results, most of the network local structure remains unaltered in the two compared conditions. Nevertheless, changes reported by RGD necessarily imply that a different cohort of regulators (i.e. transcription factors (TFs)) appear on the scene, shedding light on how the regulation of gene expression occurs when E. coli transits from suspension to biofilm. Consequently, we propose that both metrics REC and RGD should be adopted as a quantitative approach to conduct differential analyses of GRNs. A tool that implements both metrics is available as an on-line web server (http://dlab.cl/loto). PMID- 27695051 TI - Standardization of A Physiologic Hypoparathyroidism Animal Model. AB - Ideal hypoparathyroidism animal models are a prerequisite to developing new treatment modalities for this disorder. The purpose of this study was to evaluate the feasibility of a model whereby rats were parathyroidectomized (PTX) using a fluorescent-identification method and the ideal calcium content of the diet was determined. Thirty male rats were divided into surgical sham (SHAM, n = 5) and PTX plus 0, 0.5, and 2% calcium diet groups (PTX-FC (n = 5), PTX-NC (n = 10), and PTX-HC (n = 10), respectively). Serum parathyroid hormone levels decreased to non detectable levels in all PTX groups. All animals in the PTX-FC group died within 4 days after the operation. All animals survived when supplied calcium in the diet. However, serum calcium levels were higher in the PTX-HC than the SHAM group. The PTX-NC group demonstrated the most representative modeling of primary hypothyroidism. Serum calcium levels decreased and phosphorus levels increased, and bone volume was increased. All animals survived without further treatment and did not show nephrotoxicity including calcium deposits. These findings demonstrate that PTX animal models produced by using the fluorescent identification method, and fed a 0.5% calcium diet, are appropriate for hypoparathyroidism treatment studies. PMID- 27695052 TI - LDL-Cholesterol Increases the Transcytosis of Molecules through Endothelial Monolayers. AB - Cholesterol has been identified as a causative factor in numerous pathologies including atherosclerosis and cancer. One of the frequent effects of elevated cholesterol levels in humans is the compromise of endothelial function due to activation of pro-inflammatory signalling pathways. While the mechanisms involved in endothelial activation by cholesterol during an inflammatory response are well established, less is known about the mechanisms by which cholesterol may affect endothelial barrier function, which were the subject of the present study. Here we show that low density lipoprotein (LDL) increases the permeability of endothelial monolayers to high molecular weight dextrans in an LDL receptor and cholesterol-dependent manner. The increased permeability seen upon LDL treatment was not caused by disruption of cell-to-cell junctions as determined by a normal localization of VE-Cadherin and ZO-1 proteins, and no major alterations in transendothelial electrical resistance or permeability to fluorescein. We show instead that LDL increases the level of high molecular weight transcytosis and that this occurs in an LDL receptor, cholesterol and caveolae-dependent way. Our findings contribute to our understanding of the systemic pathological effects of elevated cholesterol and the transport of cargo through endothelial monolayers. PMID- 27695053 TI - Presence of Serum Ferritin before and after Bariatric Surgery: Analysis in Dentate and Edentulous Patients. AB - Society has changed its own lifestyle, specially its eating habits and physical activities, leading to excessive weight and a sedentary behavior, which has contributed to obesity increase. Bariatric surgery is the most effective treatment to obesity, allowing weight loss and its maintenance. However, it has been related high levels of iron deficiency after surgery. A person's nutritional status might be affected by total or partial tooth loss. The aim of this longitudinal prospective cohort study was to evaluate the levels of serum ferritin before and after bariatric surgery and to identify if there is a relation with tooth loss. The sample was composed of 50 patients selected and assisted at Amaral Carvalho Hospital, located in Jau city, Brazil. The use and necessity of prosthesis, dental absence or presence, and serum ferritin dosage were evaluated. Student's t test, Univariate analysis, Chi-square and Odds Ratio were adopted (p<0.05). There was no significant difference regarding the serum ferritin levels between dentate and edentulous patients prior to surgery (p = 0.436). After surgery, the serum ferritin levels were higher in edentulous patients (prosthesis users) when compared to the pre-surgical levels, and the post-surgical levels presented significant difference regarding the dentate patients (p = 0.024). It can be concluded that rehabilitated patients in postoperative period showed better levels of serum ferritin after surgical intervention. PMID- 27695054 TI - Using YouTube to Disseminate Effective Vaccination Pain Treatment for Babies. AB - BACKGROUND: Infant vaccinations are necessary for public health, but are painful, causing distress to the infant and caregivers. Breastfeeding and sucrose effectively reduce infants' pain during vaccinations, and these strategies are recommended in health care provider (HCP)-targeted education and vaccination pain guidelines. However studies show these strategies are infrequently used. YouTube is a popular medium to publicly share and watch videos, and many consumer posted YouTube videos show distressed infants being vaccinated with no pain treatment. The aims of this study were to evaluate the reach and impact of a consumer targeted YouTube video demonstrating use of effective pain reduction strategies during infant vaccinations. METHODS: A brief consumer-targeted video showing two infants being vaccinated was posted onto YouTube on October 2013. One infant was breastfed and another infant received sucrose by mouth before and during the injection. A link to a viewer survey was visible on a banner near the end of the video. An intensive strategically planned knowledge dissemination strategy using the media, social media and messages to professional organizations took place to promote the video. Data analysis of the viewer survey, YouTube analytics of the reach of the video in terms of number of views, country of viewers, and comments relating to the video took place 12 months after the video was posted. RESULTS: Twelve months after posting, the video had 65,478views, 68 comments, 245 likes, 17 dislikes, and 90 shares. Average duration of viewer time was 65% of the video. The viewer survey was completed by 156 (0.24%) viewers; 90 (58%) answered as HCPs and 66 (42%) as parents. Survey results showed that the video was persuasive; intent to use or support breastfeeding or sucrose was high in both parents and HCPs after viewing the video. Comments posted were often emotional in nature, and were related to anti-vaccination (n = 26, 38%); effectiveness or positive personal experiences (n = 21, 32%); research team comments or promotion (n = 12, 18%); pro-vaccination (n = 6, 8%) and barriers to using breastfeeding or sucrose during vaccinations (n = 3, 4%). CONCLUSION: The video posted onto YouTube demonstrating effective pain treatment during infant vaccinations was viewed by large numbers of people around the world, however the response rate to the linked survey was extremely low. Using YouTube videos for knowledge dissemination has an extensive reach, however it is difficult to evaluate impact on behaviours and practices. PMID- 27695055 TI - An Effective Method to Detect Volatile Intermediates Generated in the Bioconversion of Coal to Methane by Gas Chromatography-Mass Spectrometry after In Situ Extraction Using Headspace Solid-Phase Micro-Extraction under Strict Anaerobic Conditions. AB - Bioconversion of coal to methane has gained increased attention in recent decades because of its economic and environmental advantages. However, the mechanism of this process is difficult to study in depth, partly because of difficulties associated with the analysis of intermediates generated in coal bioconversion. In this investigation, we report on an effective method to analyze volatile intermediates generated in the bioconversion of coal under strict anaerobic conditions. We conduct in-situ extraction of intermediates using headspace solid phase micro-extraction followed by detection by gas chromatography-mass spectrometry. Bioconversion simulation equipment was modified and combined with a solid-phase micro-extraction device. In-situ extraction could be achieved by using the combined units, to avoid a breakdown in anaerobic conditions and to maintain the experiment continuity. More than 30 intermediates were identified qualitatively in the conversion process, and the variation in trends of some typical intermediates has been discussed. Volatile organic acids (C2-C7) were chosen for a quantitative study of the intermediates because of their importance during coal bioconversion to methane. Fiber coating, extraction time, and solution acidity were optimized in the solid-phase micro-extraction procedure. The pressure was enhanced during the bioconversion process to investigate the influence of headspace pressure on analyte extraction. The detection limits of the method ranged from 0.0006 to 0.02 mmol/L for the volatile organic acids and the relative standard deviations were between 4.6% and 11.5%. The volatile organic acids (C2-C7) generated in the bioconversion process were 0.01-1.15 mmol/L with a recovery range from 80% to 105%. The developed method is useful for further in-depth research on the bioconversion of coal to methane. PMID- 27695056 TI - The Fatty Acid Synthase Inhibitor Platensimycin Improves Insulin Resistance without Inducing Liver Steatosis in Mice and Monkeys. AB - OBJECTIVES: Platensimycin (PTM) is a natural antibiotic produced by Streptomyces platensis that selectively inhibits bacterial and mammalian fatty acid synthase (FAS) without affecting synthesis of other lipids. Recently, we reported that oral administration of PTM in mouse models (db/db and db/+) with high de novo lipogenesis (DNL) tone inhibited DNL and enhanced glucose oxidation, which in turn led to net reduction of liver triglycerides (TG), reduced ambient glucose, and improved insulin sensitivity. The present study was conducted to explore translatability and the therapeutic potential of FAS inhibition for the treatment of diabetes in humans. METHODS: We tested PTM in animal models with different DNL tones, i.e. intrinsic synthesis rates, which vary among species and are regulated by nutritional and disease states, and confirmed glucose-lowering efficacy of PTM in lean NHPs with quantitation of liver lipid by MRS imaging. To understand the direct effect of PTM on liver metabolism, we performed ex vivo liver perfusion study to compare FAS inhibitor and carnitine palmitoyltransferase 1 (CPT1) inhibitor. RESULTS: The efficacy of PTM is generally reproduced in preclinical models with DNL tones comparable to humans, including lean and established diet induced obese (eDIO) mice as well as non-human primates (NHPs). Similar effects of PTM on DNL reduction were observed in lean and type 2 diabetic rhesus and lean cynomolgus monkeys after acute and chronic treatment of PTM. Mechanistically, PTM lowers plasma glucose in part by enhancing hepatic glucose uptake and glycolysis. Teglicar, a CPT1 inhibitor, has similar effects on glucose uptake and glycolysis. In sharp contrast, Teglicar but not PTM significantly increased hepatic TG production, thus caused liver steatosis in eDIO mice. CONCLUSIONS: These findings demonstrate unique properties of PTM and provide proof-of-concept of FAS inhibition having potential utility for the treatment of diabetes and related metabolic disorders. PMID- 27695057 TI - The Expression and Prognostic Roles of MCMs in Pancreatic Cancer. AB - OBJECTIVES: Minichromosome maintenance (MCM) proteins play important roles in DNA replication by interacting with other factors which participate in the regulation of DNA synthesis. Abnormal over-expression of MCMs was observed in numerous malignancies, such as colorectal cancer. However, the expression of MCMs in pancreatic cancer (PC) was less investigated so far. This study was designed to analyze the expression and prognostic roles of MCM1-10 in PC based on the data provided by The Cancer Genome Atlas (TCGA). METHODS: Pearson chi2 test was applied to evaluate the association of MCMs expression with clinicopathologic indicators, and biomarkers for tumor biological behaviors. Kaplan-Meier plots and log-rank tests were used to assess survival analysis, and univariate and multivariate Cox proportional hazard regression models were used to recognize independent prognostic factors. RESULTS: MCM1-10 were generally expressed in PC samples. The levels of some molecules were markedly correlated with that of biomarkers for S phase, proliferation, gemcitabine resistance. And part of these molecules over-expression was significantly associated with indicators of disease progression, such as depth of tumor invasion and lymph node metastasis. Furthermore, MCM2, 4, 6, 8, and 10 over-expression was remarkably associated with shorter disease free survival time, and MCM2, 4,8, and 10 over-expression was associated with shorter overall survival time. Further multivariate analysis suggested that MCM8 was an independent prognostic factor for PC. CONCLUSION: MCMs abnormal over-expression was significantly associated with PC progression and prognosis. These molecules could be regarded as prognostic and therapeutic biomarkers for PC. The roles of MCMs may be vitally important and the underlying mechanisms need to be furtherinvestigated. PMID- 27695058 TI - Monitoring in Real Time the Formation and Removal of Biofilms from Clinical Related Pathogens Using an Impedance-Based Technology. AB - Bacteria found in diverse ecosystems grow in a community of aggregated cells that favors their survival and colonization. Different extracellular polymeric substances are used to entrap this multispecies community forming a biofilm, which can be associated to biotic and abiotic surfaces. This widespread and successful way of bacterial life, however, can lead to negative effects for human activity since many pathogen and spoiling bacteria form biofilms which are not easy to eradicate. Therefore, the search for novel anti-biofilm bio-active molecules is a very active research area for which simple, reliable, and fast screening methods are demanded. In this work we have successfully validated an impedance-based method, initially developed for the study of adherent eukaryotic cells, to monitor the formation of single-species biofilms of three model bacteria in real time. The xCelligence real time cell analyzer (RTCA) equipment uses specific microtiter E-plates coated with gold-microelectrodes that detect the attachment of adherent cells, thus modifying the impedance signal. In the current study, this technology allowed the distinction between biofilm-producers and non-producers of Staphylococcus aureus and Staphylococcus epidermidis, as well as the formation of Streptococcus mutans biofilms only when sucrose was present in the culture medium. Besides, different impedance values permitted discrimination among the biofilm-producing strains tested regardless of the nature of the polymeric biofilm matrix. Finally, we have continuously monitored the inhibition of staphylococcal biofilm formation by the bacteriophage phi-IPLA7 and the bacteriophage-encoded endolysin LysH5, as well as the removal of a preformed biofilm by this last antimicrobial treatment. Results observed with the impedance-based method showed high correlation with those obtained with standard approaches, such as crystal violet staining and bacteria enumeration, as well as with those obtained upon other abiotic surfaces (polystyrene and stainless steel). Therefore, this RTCA technology opens new opportunities in the biofilm research arena and its application could be further explored for other bacterial genera as well as for different bio-active molecules.

PMID- 27695059 TI - Genome-Wide Identification of miRNAs and Their Targets Involved in the Developing Internodes under Maize Ears by Responding to Hormone Signaling. AB - Internode length is one of the decisive factors affecting plant height (PH) and ear height (EH), which are closely associated with the lodging resistance, biomass and grain yield of maize. miRNAs, currently recognized as important transcriptional/ post-transcriptional regulators, play an essential role in plant growth and development. However, their roles in developing internodes under maize ears remain unclear. To identify the roles of miRNAs and their targets in the development of internodes under maize ears, six miRNA and two degradome libraries were constructed using the 7th, 8th and 9th internodes of two inbred lines, 'Xun928' and 'Xun9058', which had significantly different internode lengths. A total of 45 and 54 miRNAs showed significant changes for each pairwise comparison among the 7th, 8th and 9th internodes of 'Xun9058' and 'Xun928', respectively. The expression of 31 miRNAs showed significant changes were common to the corresponding comparison groups of the 7th, 8th and 9th internodes of 'Xun9058' and 'Xun928'. For the corresponding internodes of 'Xun9058' and 'Xun928', compared with the expression of miRNAs in the 7th, 8th and 9th internodes of 'Xun928', the numbers of up-regulated and down-regulated miRNAs were 11 and 36 in the 7th internode, 9 and 45 in the 8th internode, and 9 and 25 in the 9th internode of 'Xun9058', respectively. Moreover, 10 miRNA families containing 45 members showed significant changes at least in two internodes of 'Xun928' by comparing with the corresponding internodes of 'Xun9058'. Based on the sequencing data, 20 miRNAs related to hormone signaling among the candidates, belonging to five conserved miRNA families, were selected for expression profiling using quantitative reverse-transcription polymerase chain reaction (qRT-PCR). The five miRNA families, zma-miR160, zma-miR167, zma-miR164, zma-miR169 and zma-miR393, targeted the genes encoding auxin response factor, N-acetylcysteine domain containing protein, nuclear transcription factor Y and auxin signaling F-BOX 2 through degradome sequencing. The miRNAs might regulate their targets to respond to hormone signaling, thereby regulating the internode elongation and development under maize ear. These results provide valuable reference for understanding the possible regulation mechanism of the ILs under the ear. PMID- 27695061 TI - Identification of microRNAs with Dysregulated Expression in Status Epilepticus Induced Epileptogenesis. AB - The involvement of miRNA in mesial temporal lobe epilepsy (MTLE) pathogenesis has increasingly become a focus of epigenetic studies. Despite advances, the number of known miRNAs with a consistent expression response during epileptogenesis is still small. Addressing this situation requires additional miRNA profiling studies coupled to detailed individual expression analyses. Here, we perform a miRNA microarray analysis of the hippocampus of Wistar rats 24 hours after intra hippocampal pilocarpine-induced Status Epilepticus (H-PILO SE). We identified 73 miRNAs that undergo significant changes, of which 36 were up-regulated and 37 were down-regulated. To validate, we selected 5 of these (10a-5p, 128a-3p, 196b 5p, 352 and 324-3p) for RT-qPCR analysis. Our results confirmed that miR-352 and 196b-5p levels were significantly higher and miR-128a-3p levels were significantly lower in the hippocampus of H-PILO SE rats. We also evaluated whether the 3 miRNAs show a dysregulated hippocampal expression at three time periods (0h, 24h and chronic phase) after systemic pilocarpine-induced status epilepticus (S-PILO SE). We demonstrate that miR-128a-3p transcripts are significantly reduced at all time points compared to the naive group. Moreover, miR-196b-5p was significantly higher only at 24h post-SE, while miR-352 transcripts were significantly up-regulated after 24h and in chronic phase (epileptic) rats. Finally, when we compared hippocampi of epileptic and non epileptic humans, we observed that transcript levels of miRNAs show similar trends to the animal models. In summary, we successfully identified two novel dysregulated miRNAs (196b-5p and 352) and confirmed miR-128a-3p downregulation in SE-induced epileptogenesis. Further functional assays are required to understand the role of these miRNAs in MTLE pathogenesis. PMID- 27695062 TI - Third-Generation Sequencing and Analysis of Four Complete Pig Liver Esterase Gene Sequences in Clones Identified by Screening BAC Library. AB - AIM: Pig liver carboxylesterase (PLE) gene sequences in GenBank are incomplete, which has led to difficulties in studying the genetic structure and regulation mechanisms of gene expression of PLE family genes. The aim of this study was to obtain and analysis of complete gene sequences of PLE family by screening from a Rongchang pig BAC library and third-generation PacBio gene sequencing. METHODS: After a number of existing incomplete PLE isoform gene sequences were analysed, primers were designed based on conserved regions in PLE exons, and the whole pig genome used as a template for Polymerase chain reaction (PCR) amplification. Specific primers were then selected based on the PCR amplification results. A three-step PCR screening method was used to identify PLE-positive clones by screening a Rongchang pig BAC library and PacBio third-generation sequencing was performed. BLAST comparisons and other bioinformatics methods were applied for sequence analysis. RESULTS: Five PLE-positive BAC clones, designated BAC-10, BAC 70, BAC-75, BAC-119 and BAC-206, were identified. Sequence analysis yielded the complete sequences of four PLE genes, PLE1, PLE-B9, PLE-C4, and PLE-G2. Complete PLE gene sequences were defined as those containing regulatory sequences, exons, and introns. It was found that, not only did the PLE exon sequences of the four genes show a high degree of homology, but also that the intron sequences were highly similar. Additionally, the regulatory region of the genes contained two 720bps reverse complement sequences that may have an important function in the regulation of PLE gene expression. SIGNIFICANCE: This is the first report to confirm the complete sequences of four PLE genes. In addition, the study demonstrates that each PLE isoform is encoded by a single gene and that the various genes exhibit a high degree of sequence homology, suggesting that the PLE family evolved from a single ancestral gene. Obtaining the complete sequences of these PLE genes provides the necessary foundation for investigation of the genetic structure, function, and regulatory mechanisms of the PLE gene family. PMID- 27695063 TI - Depression among Parents Two to Six Years Following the Loss of a Child by Suicide: A Novel Prediction Model. AB - BACKGROUND: Parents who lose a child by suicide have elevated risks of depression. No clinical prediction tools exist to identify which suicide-bereaved parents will be particularly vulnerable; we aimed to create a prediction model for long-term depression for this purpose. METHOD: During 2009 and 2010 we collected data using a nationwide study-specific questionnaire among parents in Sweden who had lost a child aged 15-30 by suicide in years 2004-2007. Current depression was assessed with the Patient Health Questionnaire (PHQ-9) and a single question on antidepressant use. We considered 26 potential predictors assumed clinically assessable at the time of loss, including socio-economics, relationship status, history of psychological stress and morbidity, and suicide related circumstances. We developed a novel prediction model using logistic regression with all subsets selection and stratified cross-validation. The model was assessed for classification performance and calibration, overall and stratified by time since loss. RESULTS: In total 666/915 (73%) participated. The model showed acceptable classification performance (adjusted area under the curve [AUC] = 0.720, 95% confidence interval [CI] 0.673-0.766), but performed classification best for those at shortest time since loss. Agreement between model-predicted and observed risks was fair, but with a tendency for underestimation and overestimation for individuals with shortest and longest time since loss, respectively. The identified predictors include female sex (odds ratio [OR] = 1.84); sick-leave (OR = 2.81) or unemployment (OR = 1.64); psychological premorbidity debuting during the last 10 years, before loss (OR = 3.64), or more than 10 years ago (OR = 4.96); suicide in biological relatives (OR = 1.54); with non-legal guardianship during the child's upbringing (OR = 0.48); and non-biological parenthood (OR = 0.22) found as protective. CONCLUSIONS: Our prediction model shows promising internal validity, but should be externally validated before application. Psychological premorbidity seems to be a prominent predictor of long-term depression among suicide-bereaved parents, and thus important for healthcare providers to assess.

PMID- 27695064 TI - Studying Closed Hydrodynamic Models of "In Vivo" DNA Perfusion in Pig Liver for Gene Therapy Translation to Humans. AB - INTRODUCTION: Expressing exogenous genes after naked DNA delivery into hepatocytes might achieve sustained and high expression of human proteins. Tail vein DNA injection is an efficient procedure for gene transfer in murine liver. Hydrodynamic procedures in large animals require organ targeting, and improve with liver vascular exclusion. In the present study, two closed liver hydrofection models employing the human alpha-1-antitrypsin (hAAT) gene are compared to reference standards in order to evaluate their potential clinical interest. MATERIAL AND METHODS: A solution of naked DNA bearing the hAAT gene was retrogradely injected in 7 pig livers using two different closed perfusion procedures: an endovascular catheterization-mediated procedure (n = 3) with infrahepatic inferior vena cava and portal vein blockage; and a surgery-mediated procedure (n = 4) with completely sealed liver. Gene transfer was performed through the suprahepatic inferior cava vein in the endovascular procedure and through the infrahepatic inferior vena cava in the surgical procedure. The efficiency of the procedures was evaluated 14 days after hydrofection by quantifying the hAAT protein copies per cell in tissue and in plasma. For comparison, samples from mice (n = 7) successfully hydrofected with hAAT and healthy human liver segments (n = 4) were evaluated. RESULTS: Gene decoding occurs efficiently using both procedures, with liver vascular arrest improving its efficiency. The surgically closed procedure (sealed organ) reached higher tissue protein levels (4x10^5- copies/cell) than the endovascular procedure, though the levels were lower than in human liver (5x10^6- copies/cell) and hydrofected mouse liver (10^6- copies/cell). However, protein levels in plasma were lower (p<0.001) than the reference standards in all cases. CONCLUSION: Hydrofection of hAAT DNA to "in vivo" isolated pig liver mediates highly efficient gene delivery and protein expression in tissue. Both endovascular and surgically closed models mediate high tissue protein expression. Impairment of protein secretion to plasma is observed and might be species-related. This study reinforces the potential application of closed liver hydrofection for therapeutic purposes, provided protein secretion improves. PMID- 27695067 TI - Insulin-Like Growth Factor I Does Not Drive New Bone Formation in Experimental Arthritis. AB - INTRODUCTION: Insulin like growth factor (IGF)-I can act on a variety of cells involved in cartilage and bone repair, yet IGF-I has not been studied extensively in the context of inflammatory arthritis. The objective of this study was to investigate whether IGF-I overexpression in the osteoblast lineage could lead to increased reparative or pathological bone formation in rheumatoid arthritis and/or spondyloarthritis respectively. METHODS: Mice overexpressing IGF-I in the osteoblast lineage (Ob-IGF-I+/-) line 324-7 were studied during collagen induced arthritis and in the DBA/1 aging model for ankylosing enthesitis. Mice were scored clinically and peripheral joints were analysed histologically for the presence of hypertrophic chondrocytes and osteocalcin positive osteoblasts. RESULTS: 90-100% of the mice developed CIA with no differences between the Ob-IGF I+/- and non-transgenic littermates. Histological analysis revealed similar levels of hypertrophic chondrocytes and osteocalcin positive osteoblasts in the ankle joints. In the DBA/1 aging model for ankylosing enthesitis 60% of the mice in both groups had a clinical score 1<. Severity was similar between both groups. Histological analysis revealed the presence of hypertrophic chondrocytes and osteocalcin positive osteoblasts in the toes in equal levels. CONCLUSION: Overexpression of IGF-I in the osteoblast lineage does not contribute to an increase in repair of erosions or syndesmophyte formation in mouse models for destructive and remodeling arthritis. PMID- 27695068 TI - Enhancing Predicted Efficacy of Tumor Treating Fields Therapy of Glioblastoma Using Targeted Surgical Craniectomy: A Computer Modeling Study. AB - OBJECTIVE: The present work proposes a new clinical approach to TTFields therapy of glioblastoma. The approach combines targeted surgical skull removal (craniectomy) with TTFields therapy to enhance the induced electrical field in the underlying tumor tissue. Using computer simulations, we explore the potential of the intervention to improve the clinical efficacy of TTFields therapy of brain cancer. METHODS: We used finite element analysis to calculate the electrical field distribution in realistic head models based on MRI data from two patients: One with left cortical/subcortical glioblastoma and one with deeply seated right thalamic anaplastic astrocytoma. Field strength was assessed in the tumor regions before and after virtual removal of bone areas of varying shape and size (10 to 100 mm) immediately above the tumor. Field strength was evaluated before and after tumor resection to assess realistic clinical scenarios. RESULTS: For the superficial tumor, removal of a standard craniotomy bone flap increased the electrical field strength by 60-70% in the tumor. The percentage of tissue in expected growth arrest or regression was increased from negligible values to 30 50%. The observed effects were highly focal and targeted at the regions of pathology underlying the craniectomy. No significant changes were observed in surrounding healthy tissues. Median field strengths in tumor tissue increased with increasing craniectomy diameter up to 50-70 mm. Multiple smaller burr holes were more efficient than single craniectomies of equivalent area. Craniectomy caused no significant field enhancement in the deeply seated tumor, but rather a focal enhancement in the brain tissue underlying the skull defect. CONCLUSIONS: Our results provide theoretical evidence that small and clinically feasible craniectomies may provide significant enhancement of TTFields intensity in cerebral hemispheric tumors without severely compromising brain protection or causing unacceptable heating in healthy tissues. A clinical trial is being planned to validate safety and efficacy. PMID- 27695069 TI - Differences in the Epidemiology of Childhood Infections with Avian Influenza A H7N9 and H5N1 Viruses. AB - The difference between childhood infections with avian influenza viruses A(H5N1) and A(H7N9) remains an unresolved but critically important question. We compared the epidemiological characteristics of 244 H5N1 and 41 H7N9 childhood cases (<15 years old), as well as the childhood cluster cases of the two viruses. Our findings revealed a higher proportion of H5N1 than H7N9 childhood infections (31.1% vs. 6.4%, p = 0.000). However, the two groups did not differ significantly in age (median age: 5.0 vs. 5.5 y, p = 0.0651). The proportion of clustered cases was significantly greater among children infected with H5N1 than among children infected with H7N9 [46.7% (71/152) vs. 23.6% (13/55), p = 0.005], and most of the childhood cases were identified as secondary cases [46.4% (45/97) vs. 33.3% (10/30), p = 0.000]. Mild status accounted for 79.49% and 22.66%, severe status for 17.95% and 2.34%, and fatal cases for 2.56% and 75.00% of the H7N9 and H5N1 childhood infection cases (all p<0.05), respectively. The fatality rates for the total, index and secondary childhood cluster cases were 52.86% (37/70), 88.5% (23/26) and 33.33% (15/45), respectively, in the H5N1 group, whereas no fatal H7N9 childhood cluster cases were identified. In conclusion, lower severity and greater transmission were found in the H7N9 childhood cases than in the H5N1 childhood cases. PMID- 27695066 TI - A Novel Interaction between Tryptophan Hydroxylase 2 (TPH2) Gene Polymorphism (rs4570625) and BDNF Val66Met Predicts a High-Risk Emotional Phenotype in Healthy Subjects. AB - Poor inhibitory processing of negative emotional content is central to many psychiatric disorders, including depression and anxiety. Moreover, increasing evidence suggests that core aspects of emotion-inhibitory processing are largely inherited and as such may represent a key intermediate or risk-related phenotype for common affective diseases (e.g., unipolar depressive, anxiety disorders). The current study employed a candidate-gene approach in order to most effectively examine this complex behavioral phenotype. We examined the novel interaction between BDNF (Val66Met) and TPH2 (rs4570625) polymorphisms and their influence on behavioral inhibition of negative emotion in two independent investigations of healthy adults. BDNF Met carriers consistently report greater symptoms of affective disease and display corresponding behavioral rigidity, while TPH2 T carriers display poor inhibitory processing. These genotypes are traditionally perceived as 'risk' genotypes when compared to their respective major Val and G homozygous genotypes, but evidence is mixed. Recent studies in humans and mutant mouse models suggest biological epistasis between BDNF and genes involved in serotonin regulation. Moreover, polymorphisms in the TPH2 gene may have greater influence on serotonergic function than other more commonly studied polymorphisms (e.g., 5-HTTLPR). We observed consistent evidence across two different emotion inhibition paradigms, one with high internal validity (Study 1, n = 119) and one with high ecological validity (Study 2, n = 115) that the combination of Val/Val and G/G genotypes was clearly associated with impaired inhibition of negative emotional content. This was followed by individuals carrying the BDNF-Met allele (including Met/Val and Met/Met) when combined with the TPH2-T allele (including T/G and T/T combinations). The consistency of these results across tasks and studies suggests that these two groups may be particularly vulnerable to the most common psychiatric disorders and should be targets for future clinical investigation. PMID- 27695070 TI - Off-Road Vehicle Crash Risk during the Six Months after a Birthday. AB - BACKGROUND: Off-road vehicles are popular and thrilling for youth outside urban settings, yet sometimes result in a serious crash that requires emergency medical care. The relation between birthdays and the subsequent risk of an off-road vehicle crash is unknown. METHODS: We conducted a population-based before-and after longitudinal analysis of youth who received emergency medical care in Ontario, Canada, due to an off-road vehicle crash between April 1, 2002, and March 31, 2014. We identified youth injured in an off-road vehicle crash through population-based health-care databases of individuals treated for medical emergencies. We included youth aged 19 years or younger, distinguishing juniors (age <= 15 years) from juveniles (age >= 16 years). RESULTS: A total 32,777 youths accounted for 35,202 emergencies due to off-road vehicle crashes within six months of their nearest birthday. Comparing the six months following a birthday to the six months prior to a birthday, crashes increased by about 2.7 events per 1000 juniors (18.3 vs 21.0, p < 0.0001). The difference equaled a 15% increase in relative risk (95% confidence interval 12 to 18). The increase extended for months following a birthday, was not observed for traffic crashes due to on-road vehicles, and was partially explained by a lack of helmet wearing. As expected, off-road crash risks did not change significantly following a birthday among juveniles (19.2 vs 19.8, p = 0.61). CONCLUSIONS: Off-road vehicle crashes leading to emergency medical care increase following a birthday in youth below age 16 years. An awareness of this association might inform public health messages, gift-giving practices, age-related parental permissions, and prevention by primary care physicians. PMID- 27695071 TI - Differences between Practice Patterns of Conventional and Naturopathic GPs in Germany. AB - BACKGROUND: Limited evidence exists whether practice patterns of general practitioners (GPs) who have additionally completed training in naturopathy are different from those of conventional GPs. We aimed to assess and compare practice patterns of GPs in conventional and naturopathic GPs. METHODS: Routine data from 41 GPs (31 with and 11 without additional qualification in NP, respectively) and 180,789 patients, drawn from the CONTinuous morbidity registration Epidemiologic NeTwork (CONTENT)-registry and collected between 2009 and 2014, were used. To assess practice patterns determinants of (non-)phytopharmaceutical prescriptions, referrals and hospitalizations were analyzed using mixed-effects Poisson regression models. As explanatory variables, the qualification of the GP in NM, the age group and sex of the patient, as well as bivariate interactions between these variables were considered. RESULTS: GPs additionally qualified in naturopathy exhibited higher rates of phytopharmaceutical prescriptions (p<0.034; independent effect) compared to conventional GPs. This association was not observed with respect to non-phytopharmaceutical prescriptions. However, interaction effects between qualification and age group as well as sex were present with respect to both phytopharmaceutical and non-phytopharmaceutical prescriptions (all p<0.001). No further independent association existed between qualification and either referral rates or hospitalization rates, but again interactions between qualification and age group and sex (only referrals) were statistically significant (all p<0.0001). CONCLUSION: The results show that the rate of phyto-pharmaceutical prescriptions are generally higher when the GP has an additional qualification in naturopathy. Further differences in practice patterns between conventional and naturopathy GPs could be subject to certain age groups and sex. However, the magnitude of these differences seem to be rather small. PMID- 27695073 TI - Type of High School Predicts Academic Performance at University Better than Individual Differences. AB - Psychological correlates of academic performance have always been of high relevance to psychological research. The relation between psychometric intelligence and academic performance is one of the most consistent and well established findings in psychology. It is hypothesized that intelligence puts a limit on what an individual can learn or achieve. Moreover, a growing body of literature indicates a relationship between personality traits and academic performance. This relationship helps us to better understand how an individual will learn or achieve their goals. The aim of this study is to further investigate the relationship between psychological correlates of academic performance by exploring the potentially moderating role of prior education. The participants in this study differed in the type of high school they attended. They went either to gymnasium, a general education type of high school that prepares students specifically for university studies, or to vocational school, which prepares students both for the labour market and for further studies. In this study, we used archival data of psychological testing during career guidance in the final year of high school, and information about the university graduation of those who received guidance. The psychological measures included intelligence, personality and general knowledge. The results show that gymnasium students had greater chances of performing well at university, and that this relationship exceeds the contribution of intelligence and personality traits to university graduation. Moreover, psychological measures did not interact with type of high school, which indicates that students from different school types do not profit from certain individual characteristics. PMID- 27695072 TI - Image Restoration and Analysis of Influenza Virions Binding to Membrane Receptors Reveal Adhesion-Strengthening Kinetics. AB - With the development of single-particle tracking (SPT) microscopy and host membrane mimics called supported lipid bilayers (SLBs), stochastic virus-membrane binding interactions can be studied in depth while maintaining control over host receptor type and concentration. However, several experimental design challenges and quantitative image analysis limitations prevent the widespread use of this approach. One main challenge of SPT studies is the low signal-to-noise ratio of SPT videos, which is sometimes inevitable due to small particle sizes, low quantum yield of fluorescent dyes, and photobleaching. These situations could render current particle tracking software to yield biased binding kinetic data caused by intermittent tracking error. Hence, we developed an effective image restoration algorithm for SPT applications called STAWASP that reveals particles with a signal-to-noise ratio of 2.2 while preserving particle features. We tested our improvements to the SPT binding assay experiment and imaging procedures by monitoring X31 influenza virus binding to alpha2,3 sialic acid glycolipids. Our interests lie in how slight changes to the peripheral oligosaccharide structures can affect the binding rate and residence times of viruses. We were able to detect viruses binding weakly to a glycolipid called GM3, which was undetected via assays such as surface plasmon resonance. The binding rate was around 28 folds higher when the virus bound to a different glycolipid called GD1a, which has a sialic acid group extending further away from the bilayer surface than GM3. The improved imaging allowed us to obtain binding residence time distributions that reflect an adhesion-strengthening mechanism via multivalent bonds. We empirically fitted these distributions using a time-dependent unbinding rate parameter, koff, which diverges from standard treatment of koff as a constant. We further explain how to convert these models to fit ensemble-averaged binding data obtained by assays such as surface plasmon resonance. PMID- 27695074 TI - Ncm, a Photolabile Group for Preparation of Caged Molecules: Synthesis and Biological Application. AB - Ncm, 6-nitrocoumarin-7-ylmethyl, is a photolabile protective group useful for making "caged" molecules. Ncm marries the reliable photochemistry of 2 nitrobenzyl systems with the excellent stability and spectroscopic properties of the coumarin chromophore. From simple, commercially available starting materials, preparation of Ncm and its caged derivatives is both quick and easy. Photorelease of Ncm-caged molecules occurs on the microsecond time scale, with quantum efficiencies of 0.05-0.08. We report the synthesis and physical properties of Ncm and its caged derivatives. The utility of Ncm-caged glutamate for neuronal photostimulation is demonstrated in cultured hippocampal neurons and in brain slice preparations.

PMID- 27695075 TI - Risk Factors for Poor Adherence to Betaferon(r) Treatment in Patients with Relapsing-Remitting Multiple Sclerosis or Clinically Isolated Syndrome. AB - INTRODUCTION: Adherence to treatment, including early treatment discontinuation, in patients with multiple sclerosis or clinically isolated syndrome can be affected by: treatment tolerability, route of drug administration, patient age, disease duration, comorbidities, medical care, and support from their caregivers. AIM: This study aimed to identify the risk factors for poor adherence to Betaferon(r) treatment, including early discontinuation and omitting doses. MATERIALS AND METHODS: 852 adult patients treated with Betaferon participated in this 24-month study. All patients were interviewed using the Risk of Drop-out Questionnaire, the Center for Epidemiologic Studies Depression Scale and the Kurtzke Expanded Disability Status Scale. RESULTS: Patients who stopped therapy were younger (p = 0.003) had a higher mean EDSS score (p = 0.022), higher mean number of relapses (p = 0.017), and reported more often fear of injection (p = 0.027) and adverse events (p = 0.007) than those who did not stop treatment. Comparing patients who stopped therapy in the first and the second year, patients who stopped therapy in the first year of treatment more frequently reported flu like symptoms and fever, and those who stopped therapy in the second year reported-ineffectiveness of treatment and disease progression. Multivariable logistic regression models confirmed that young age, short disease duration, advanced and progressing disease, and poor Betaferon tolerability were related to premature treatment discontinuation. The risk of omitting a dose during therapy was increased in patients who were working or studying, who had more advanced disease or more adverse events, and in patients who received less support from their caregivers. CONCLUSIONS: Several reasons may lead to problems with adherence to Betaferon treatment. Patients at higher risk of discontinuing treatment need to be identified early to make caregivers' support available to them. PMID- 27695078 TI - Enhancing Extraction of Drug-Drug Interaction from Literature Using Neutral Candidates, Negation, and Clause Dependency. AB - MOTIVATION: Supervised biomedical relation extraction plays an important role in biomedical natural language processing, endeavoring to obtain the relations between biomedical entities. Drug-drug interactions, which are investigated in the present paper, are notably among the critical biomedical relations. Thus far many methods have been developed with the aim of extracting DDI relations. However, unfortunately there has been a scarcity of comprehensive studies on the effects of negation, complex sentences, clause dependency, and neutral candidates in the course of DDI extraction from biomedical articles. RESULTS: Our study proposes clause dependency features and a number of features for identifying neutral candidates as well as negation cues and scopes. Furthermore, our experiments indicate that the proposed features significantly improve the performance of the relation extraction task combined with other kernel methods. We characterize the contribution of each category of features and finally conclude that neutral candidate features have the most prominent role among all of the three categories. PMID- 27695077 TI - Meta-Review of the Quantity and Quality of Evidence for Knee Arthroplasty Devices. AB - INTRODUCTION: Some cardiovascular devices are licensed based on limited evidence, potentially exposing patients to devices that are not safe or effective. Research is needed to ascertain if the same is true of other types of medical devices. Knee arthroplasty is a widely-used surgical procedure yet implant failures are not uncommon. The purpose of this study was to characterize available evidence on the safety and effectiveness of knee implants. METHODS: A review of primary studies included in health technology assessments (HTA) on total (TKA) and unicompartmental knee arthroplasty (UKA) was conducted. MEDLINE, EMBASE, CINAHL, Cochrane Library and Biotechnology & BioEngineering Abstracts were searched from 2005 to 2014, plus journal tables of contents and 32 HTA web sites. Patients were aged 18 and older who underwent primary TKA or UKA assessed in cohort or randomized controlled studies. Summary statistics were used to report study characteristics. RESULTS: A total of 265 eligible primary studies published between 1986 and 2014 involving 59,217 patients were identified in 10 HTAs (2 low, 7 moderate, 1 high risk of bias). Most evaluated TKA (198, 74.5%). The quality of evidence in primary studies was limited. Most studies were industry funded (23.8%) or offered no declaration of funding or conflict of interest (44.9%); based on uncontrolled single cohorts (58.5%), enrolled fewer than 100 patients (66.4%), and followed patients for 2 years or less (UKA: single cohort 29.8%, comparative cohort 16.7%, randomized trial 25.0%; TKA: single cohort 25.0%, comparative cohort 31.4%, randomized trial 48.6%). Furthermore, most devices were evaluated in only one study (55.3% TKA implants, 61.1% UKA implants). CONCLUSIONS: Patients, physicians, hospitals and payers rely on poor quality evidence to support decisions about knee implants. Further research is needed to explore how decisions about the use of devices are currently made, and how the evidence base for device safety and effectiveness can be strengthened. PMID- 27695079 TI - Pretreatment Neutrophil to Lymphocyte Ratio Is Associated with Poor Survival in Patients with Stage I-III Non-Small Cell Lung Cancer. AB - BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR) has been shown to be a prognostic indicator in several types of cancer. We aimed to investigate the association between NLR and survival in surgery-treated non-small cell lung cancer (NSCLC) patients. STUDY DESIGN: This large retrospective study included 1,245 patients who underwent initial surgery for stage I-III NSCLC at The University of Texas MD Anderson Cancer Center between December 2002 and November 2010. We analyzed the relationship of NLR with clinicopathological variables, local recurrence-free survival (LRFS), distant recurrence-free survival (DRFS), recurrence-free survival (RFS), overall survival (OS), and disease-specific survival (DSS) in patients with high or low NLR using Kaplan-Meier method. Hazard ratios (HRs) with 95% confidence intervals (CIs) were used to assess the prognostic strength of NLR. RESULTS: There was a statistically significant association between the pretreatment NLR and histology type (P = 0.003) and tumor grade (P = 0.028). At a median follow-up time of 50.6 months, high NLR was associated with reduced DRFS (P = 0.011), OS (P < 0.0001) and DSS (P = 0.004); it was not associated with LRFS and RFS. Multivariable Cox analysis further revealed that NLR (P = 0.027), pathologic stage (P < 0.0001) and lymphovascular invasion (P < 0.0001) were strong independent predictors for DRFS. NLR was also an independent marker predicting poor OS (P = 0.002) and DSS (P = 0.017). CONCLUSION: The pretreatment NLR can serve as a biomarker to predict distant recurrence and death in stage I-III NSCLC patients. Combination of NLR and pathologic stage can better predict the OS and DSS in stage I-II NSCLC patients.

AB - We consider a cheap-talk setting that mimics the situation where an incumbent firm (the sender) is endowed with incentives to understate the true size of the market demand to two potential entrants (the receivers). Although our experimental data reveals that the senders' messages convey truthful information and this is picked up by the receivers, this overcommunication (relative to standard theoretical prediction) does not enhance efficient entry levels (and payoffs) to beyond what can be achieved without communication. The reason is that receivers fail to optimally translate the information received in their entry decision, possibly due to overcautiousness.

AB - Mucopolysaccharidosis type II (MPS II, Hunter syndrome) is an X-linked genetic disorder caused by a deficiency of iduronate 2-sulfatase (IDS), and missense mutations comprising about 30% of the mutations responsible for MPS II result in heterogeneous phenotypes ranging from the severe to the attenuated form. To elucidate the basis of MPS II from the structural viewpoint, we built structural models of the wild type and mutant IDS proteins resulting from 131 missense mutations (phenotypes: 67 severe and 64 attenuated), and analyzed the influence of each amino acid substitution on the IDS structure by calculating the accessible surface area, the number of atoms affected and the root-mean-square distance. The results revealed that the amino acid substitutions causing MPS II were widely spread over the enzyme molecule and that the structural changes of the enzyme protein were generally larger in the severe group than in the attenuated one. Coloring of the atoms influenced by different amino acid substitutions at the same residue showed that the structural changes influenced the disease progression. Based on these data, we constructed a database of IDS mutations as to the structures of mutant IDS proteins. PMID- 27695080 TI - Amino Acid Permeases and Virulence in Cryptococcus neoformans. AB - Fungal opportunistic pathogens colonize various environments, from plants and wood to human and animal tissue. Regarding human pathogens, one great challenge during contrasting niche occupation is the adaptation to different conditions, such as temperature, osmolarity, salinity, pressure, oxidative stress and nutritional availability, which may constitute sources of stress that need to be tolerated and overcome. As an opportunistic pathogen, C. neoformans faces exactly these situations during the transition from the environment to the human host, encountering nutritional constraints. Our previous and current research on amino acid biosynthetic pathways indicates that amino acid permeases are regulated by the presence of the amino acids, nitrogen and temperature. Saccharomyces cerevisiae and Candida albicans have twenty-four and twenty-seven genes encoding amino acid permeases, respectively; conversely, they are scarce in number in Basidiomycetes (C. neoformans, Coprinopsis cinerea and Ustilago maydis), where nine to ten permease genes can be found depending on the species. In this study, we have demonstrated that two amino acid permeases are essential for virulence in C. neoformans. Our data showed that C. neoformans uses two global and redundant amino acid permeases, Aap4 and Aap5 to respond correctly to thermal and oxidative stress. Double deletion of these permeases causes growth arrest in C. neoformans at 37 degrees C and in the presence of hydrogen peroxide. The inability to uptake amino acid at a higher temperature and under oxidative stress also led to virulence attenuation in vivo. Our data showed that thermosensitivity caused by the lack of permeases Aap4 and Aap5 can be remedied by alkaline conditions (higher pH) and salinity. Permeases Aap4 and Aap5 are also required during fluconazole stress and they are the target of the plant secondary metabolite eugenol, a potent antifungal inhibitor that targets amino acid permeases. In summary, our work unravels (i) interesting physiological property of C. neoformans regarding its amino acid uptake system; (ii) an important aspect of virulence, which is the need for amino acid permeases during thermal and oxidative stress resistance and, hence, host invasion and colonization; and (iii) provides a convenient prototype for antifungal development, which are the amino acid permeases Aap4/Aap5 and their inhibitor.

AB - Th17 cells are a subset of CD4+ T cells known to play a central role in the pathogenesis of many autoimmune diseases, as well as in the defense against some extracellular bacteria and fungi. However, Th17 cells are not believed to have a significant function against intracellular infections. In contrast to this paradigm, we have discovered that Th17 cells provide robust protection against Trypanosoma cruzi, the intracellular protozoan parasite that causes Chagas disease. Th17 cells confer significantly stronger protection against T. cruzi related mortality than even Th1 cells, traditionally thought to be the CD4+ T cell subset most important for immunity to T. cruzi and other intracellular microorganisms. Mechanistically, Th17 cells can directly protect infected cells through the IL-17A-dependent induction of NADPH oxidase, involved in the phagocyte respiratory burst response, and provide indirect help through IL-21 dependent activation of CD8+ T cells. The discovery of these novel Th17 cell mediated direct protective and indirect helper effects important for intracellular immunity highlights the diversity of Th17 cell roles, and increases understanding of protective T. cruzi immunity, aiding the development of therapeutics and vaccines for Chagas disease.

AB - The bacterial communities played important roles in the high productivity mangrove ecosystem. In this study, we investigated the vertical distributions of rhizosphere bacteria from three mangrove species (Bruguiera gymnorrhiza, Kandelia candel and Aegiceras corniculatum) in Beilun Estuary, China using high throughput DNA pyrosequencing of the 16S rRNA gene. Phylogenetic analysis showed that bacterial communities from mangrove rhizosphere sediments were dominated by Proteobacteria (mostly Deltaproteobacteria and Gammaproteobacteria), followed by Chloroflexi, Bacteroidetes, Planctomycetes and Acidobacteria. However, the ANOVA analysis on Shannon and Chao1 indices indicated that bacterial communities among sediments of the three mangrove species varied more strongly than the sampling depths. In addition, the PCA result demonstrated that the bacterial communities could be separated into three groups according to the mangrove species. Moreover, the dominated orders Rhodospirillales, GCA004 and envOPS12 were significantly different among sediments of the three mangrove species. The results of this study provided valuable information about the distribution feature of rhizosphere bacteria from Chinese mangrove plants and shed insights into biogeochemical transformations driven by bacteria in rhizosphere sediments. PMID- 27695085 TI - GM-CSF Down-Regulates TLR Expression via the Transcription Factor PU.1 in Human Monocytes. AB - Toll-like receptors (TLR) are crucial sensors of microbial agents such as bacterial or viral compounds. These receptors constitute key players in the induction of inflammation, e.g. in septic or chronic inflammatory diseases. Colony-stimulating factors (CSFs) such as granulocyte-macrophage-CSF (GM-CSF) or granulocyte-CSF (G-CSF) have been extensively investigated in their capacity to promote myelopoiesis in febrile neutropenia or to overcome immunosuppression in patients suffering from sepsis-associated neutropenia or from monocytic immunoincompetence. We report here that GM-CSF, downregulates TLR1, TLR2 and TLR4 in a time- and dose-dependent fashion in human monocytes. Diminished pathogen recognition receptor expression was accompanied by reduced downstream p38 and extracellular-signal-regulated kinase (ERK) signaling upon lipoteichoic acid (LTA) and lipopolysaccharide (LPS) binding-and accordingly led to impaired proinflammatory cytokine production. Knockdown experiments of the transcription factors PU.1 and VentX showed that GM-CSF driven effects on TLR regulation is entirely PU.1 but not VentX dependent. We further analysed monocyte TLR and CD14 expression upon exposure to the IMID(r) immunomodulatory drug Pomalidomide (CC 4047), a Thalidomide analogue known to downregulate PU.1. Indeed, Pomalidomide in part reversed the GM-CSF-mediated effects. Our data indicate a critical role of PU.1 in the regulation of TLR1, 2, 4 and of CD14, thus targeting PU.1 ultimately results in TLR modulation. The PU.1 mediated immunomodulatory properties of GM CSF should be taken into consideration upon usage of GM-CSF in inflammatory or infection-related conditions. PMID- 27695086 TI - Performance of the Malay Audit of Diabetes Dependent Quality of Life-18 and Associates of Quality of Life among Patients with Type 2 Diabetes Mellitus from Major Ethnic Groups of Malaysia. AB - INTRODUCTION: Diabetes Mellitus (DM) is notorious for its metabolic effect, acute and chronic complications and impact on Quality of Life (QoL). Successful intervention to improve QoL necessitates a valid and reliable measurement tool to identify areas of concern to patients with diabetes. OBJECTIVES: To (1) assess the factor structure of the Malay Audit of Diabetes Dependent Quality of Life-18 (ADDQoL-18) questionnaire; (2) determine the impact of DM on QoL; and (3) identify areas of concern to patients with type 2 DM from three major ethnic groups in Malaysia. METHODS: Data was obtained from a cross sectional study involving 256 patients with type 2 DM attending the diabetes clinic of the National University of Malaysia Medical Centre. The Malay version of ADDQoL-18 survey was translated from its English version according to standard guidelines and administered by a trained research assistant. Exploratory Factor Analysis (EFA) with oblimin rotation was used to determine factor structure of the data. Confirmatory Factor Analysis (CFA) was used to confirm the factor structure. Hierarchical liner regression was used to determine factors associated with QoL. RESULTS: Unforced factor solution yielded two factors for the whole sample. Forced one factor solution was ascertained for the whole sample and for each ethnic group. Loadings ranged between 0.588 and 0.949. Reliability coefficients were all higher than 0.955. CFA showed that the two factor model had better fit statistics. QoL was associated with the use of insulin and desired glycaemic control, longer diabetes duration, worry about diabetes, and diabetes complications. CONCLUSIONS: The Malay ADDQoL-18 is a valid tool to be used among patients with diabetes from different ethnic groups in Malaysia. The use of insulin to achieve desired glycaemic control had more negative impact on QoL than the use of tablets and/or dietary changes. PMID- 27695087 TI - Production, Quality Control, Stability and Pharmacotoxicity of a Malaria Vaccine Comprising Three Highly Similar PfAMA1 Protein Molecules to Overcome Antigenic Variation. AB - Plasmodium falciparum apical membrane antigen 1 (PfAMA1) is a leading asexual blood stage vaccine candidate for malaria. In preparation for clinical trials, three Diversity Covering (DiCo) PfAMA1 ectodomain proteins, designed to overcome the intrinsic polymorphism that is present in PfAMA1, were produced under Good Manufacturing Practice (GMP) in Pichia pastoris. Using identical methodology, the 3 strains were cultivated in 70-L scale fed-batch fermentations and PfAMA1-DiCos were purified by two chromatography steps, an ultrafiltration/diafiltration procedure and size exclusion chromatography, resulting in highly pure (>95%) PfAMA1-DiCo1, PfAMA1 DiCo2 and PfAMA1 DiCo3, with final yields of 1.8, 1.9 and 1.3 gram, respectively. N-terminal determinations showed that approximately 50% of each of the proteins lost 12 residues from their N-terminus, in accordance with SDS-PAGE (2 main bands) and MS-data. Under reducing conditions a site of limited proteolytic cleavage within a disulphide bonded region became evident. The three proteins quantitatively bound to the mAb 4G2 that recognizes a conformational epitope, suggesting proper folding of the proteins. The lyophilized Drug Product (1:1:1 mixture of PfAMA1-DiCo1, DiCo2, DiCo3) fulfilled all pre-set release criteria (appearance, dissolution rate, identity, purity, protein content, moisture content, sub-visible particles, immuno-potency (after reconstitution with adjuvant), abnormal toxicity, sterility and endotoxin), was stable in accelerated and real-time stability studies at -20 degrees C for over 24 months. When formulated with adjuvants selected for clinical phase I evaluation, the Drug Product did not show adverse effect in a repeated-dose toxicity study in rabbits. The Drug Product has entered a phase Ia/Ib clinical trial. PMID- 27695088 TI - Vaccine Strain-Specificity of Protective HLA-Restricted Class 1 P. falciparum Epitopes. AB - A DNA prime/adenovirus boost malaria vaccine encoding Plasmodium falciparum strain 3D7 CSP and AMA1 elicited sterile clinical protection associated with CD8+ T cell interferon-gamma (IFN-gamma) cells responses directed to HLA class 1 restricted AMA1 epitopes of the vaccine strain 3D7. Since a highly effective malaria vaccine must be broadly protective against multiple P. falciparum strains, we compared these AMA1 epitopes of two P. falciparum strains (7G8 and 3D7), which differ by single amino acid substitutions, in their ability to recall CD8+ T cell activities using ELISpot and flow cytometry/intracellular staining assays. The 7G8 variant peptides did not recall 3D7 vaccine-induced CD8+ T IFN gamma cell responses in these assays, suggesting that protection may be limited to the vaccine strain. The predicted MHC binding affinities of the 7G8 variant epitopes were similar to the 3D7 epitopes, suggesting that the amino acid substitutions of the 7G8 variants may have interfered with TCR recognition of the MHC:peptide complex or that the 7G8 variant may have acted as an altered peptide ligand. These results stress the importance of functional assays in defining protective epitopes. Clinical Trials Registrations: NCT00870987, NCT00392015. PMID- 27695089 TI - No Compensatory Relationship between the Innate and Adaptive Immune System in Wild-Living European Badgers. AB - The innate immune system provides the primary vertebrate defence system against pathogen invasion, but it is energetically costly and can have immune pathological effects. A previous study in sticklebacks found that intermediate major histocompatibility complex (MHC) diversity correlated with a lower leukocyte coping capacity (LCC), compared to individuals with fewer, or many, MHC alleles. The organization of the MHC genes in mammals, however, differs to the highly duplicated MHC genes in sticklebacks by having far fewer loci. Using European badgers (Meles meles), we therefore investigated whether innate immune activity, estimated functionally as the ability of an individual's leukocytes to produce a respiratory burst, was influenced by MHC diversity. We also investigated whether LCC was influenced by factors such as age-class, sex, body condition, season, year, neutrophil and lymphocyte counts, and intensity of infection with five different pathogens. We found that LCC was not associated with specific MHC haplotypes, MHC alleles, or MHC diversity, indicating that the innate immune system did not compensate for the adaptive immune system even when there were susceptible MHC alleles/haplotypes, or when the MHC diversity was low. We also identified a seasonal and annual variation of LCC. This temporal variation of innate immunity was potentially due to physiological trade-offs or temporal variation in pathogen infections. The innate immunity, estimated as LCC, does not compensate for MHC diversity suggests that the immune system may function differently between vertebrates with different MHC organizations, with implications for the evolution of immune systems in different taxa.

AB - Differential analysis of outer membrane composition of S. Enteritidis strains, resistant to 50% normal human serum (NHS) was performed in order to find factors influencing the resistance to higher concentrations of NHS. Ten S. Enteritidis clinical strains, resistant to 50% NHS, all producing very long lipopolysaccharide, were subjected to the challenge of 75% NHS. Five extreme strains: two resistant and three sensitive to 75% NHS, were chosen for the further analysis of outer membrane proteins composition. Substantial differences were found in the levels of particular outer membrane proteins between resistant and sensitive strains, i.e. outer membrane protease E (PgtE) was present mainly in resistant strains, while sensitive strains possessed a high level of flagellar hook-associated protein 2 (FliD) and significantly higher levels of outer membrane protein A (OmpA). PMID- 27695091 TI - CERAMIC: Case-Control Association Testing in Samples with Related Individuals, Based on Retrospective Mixed Model Analysis with Adjustment for Covariates. AB - We consider the problem of genetic association testing of a binary trait in a sample that contains related individuals, where we adjust for relevant covariates and allow for missing data. We propose CERAMIC, an estimating equation approach that can be viewed as a hybrid of logistic regression and linear mixed-effects model (LMM) approaches. CERAMIC extends the recently proposed CARAT method to allow samples with related individuals and to incorporate partially missing data. In simulations, we show that CERAMIC outperforms existing LMM and generalized LMM approaches, maintaining high power and correct type 1 error across a wider range of scenarios. CERAMIC results in a particularly large power increase over existing methods when the sample includes related individuals with some missing data (e.g., when some individuals with phenotype and covariate information have missing genotype), because CERAMIC is able to make use of the relationship information to incorporate partially missing data in the analysis while correcting for dependence. Because CERAMIC is based on a retrospective analysis, it is robust to misspecification of the phenotype model, resulting in better control of type 1 error and higher power than that of prospective methods, such as GMMAT, when the phenotype model is misspecified. CERAMIC is computationally efficient for genomewide analysis in samples of related individuals of almost any configuration, including small families, unrelated individuals and even large, complex pedigrees. We apply CERAMIC to data on type 2 diabetes (T2D) from the Framingham Heart Study. In a genome scan, 9 of the 10 smallest CERAMIC p-values occur in or near either known T2D susceptibility loci or plausible candidates, verifying that CERAMIC is able to home in on the important loci in a genome scan. PMID- 27695093 TI - Association between Peer Cigarette Smoking and Electronic Cigarette Smoking among Adolescent Nonsmokers: A National Representative Survey. AB - We assessed the association between electronic cigarette (e-cigarette) use and peer cigarette smoking, a major risk factor for the initiation of cigarette smoking in adolescents. Data from the 2013 Korea Youth Risk Behavior Web-based Survey of 65,753 nonsmokers aged 13-18 years were analyzed using multiple logistic regression. A total of 3.8% of the Korean adolescents were 'ever e cigarette' users and 1.2% were current users. Adjusted odds ratios (ORs) for current and ever e-cigarette use compared to those whose closest friends were non smokers ranged from 2.05 (95% confidence interval [CI], 1.82-2.30) to 5.50 (95% CI, 4.77-6.34), and from 2.23 (95% CI, 1.77-2.81) to 7.82 (95% CI, 5.97-10.25) for those who had 'some' close friends to 'most/all' friends who smoked, respectively. The slopes of the adjusted ORs for e-cigarette use in 'never smokers' were more than twice as steep as those in 'former smokers', showing a significant interaction effect between the proportion of smoking closest friends and cigarette smoking status (never or former smokers) (p<0.001 for interaction). Peer cigarette smoking had a significant association with e-cigarette use in adolescent nonsmokers, and this association was greater on never smokers than former smokers. PMID- 27695092 TI - Overexpression of Ribosomal RNA in the Development of Human Cervical Cancer Is Associated with rDNA Promoter Hypomethylation. AB - The ribosomal RNA (rRNA) gene encodes rRNA for protein synthesis. Aberrant expression of the rRNA gene has been generally observed in tumor cells and levels of its promoter methylation as an epigenetic regulator affect rRNA gene transcription. The possible relationship between expression and promoter methylation of rDNA has not been examined in human clinical cervical cancer. Here we investigate rRNA gene expression by quantitative real time PCR, and promoter methylation levels by HpaII/MspI digestion and sodium bisulfite sequencing in the development of human cervical cancer. We find that indeed rRNA levels are elevated in most of cervical intraepithelial neoplasia (CIN) specimens as compared with non-cancer tissues. The rDNA promoter region in cervical intraepithelial neoplasia (CIN) tissues reveals significant hypomethylation at cytosines in the context of CpG dinucleotides, accompanied with rDNA chromatin decondensation. Furthermore treatment of HeLa cells with the methylation inhibitor drug 5-aza-2'-deoxycytidine (DAC) demonstrates the negative correlation between the expression of 45S rDNA and the methylation level in the rDNA promoter region. These data suggest that a decrease in rDNA promoter methylation levels can result in an increase of rRNA synthesis in the development of human cervical cancer. PMID- 27695094 TI - Estimating Common Growth Patterns in Juvenile Chinook Salmon (Oncorhynchus tshawytscha) from Diverse Genetic Stocks and a Large Spatial Extent. AB - Life history variation in Pacific salmon (Oncorhynchus spp.) supports species resilience to natural disturbances and fishery exploitation. Within salmon species, life-history variation often manifests during freshwater and estuarine rearing, as variation in growth. To date, however, characterizing variability in growth patterns within and among individuals has been difficult via conventional sampling methods because of the inability to obtain repeated size measurements. In this study we related otolith microstructures to growth rates of individual juvenile Chinook salmon (O. tshawytscha) from the Columbia River estuary over a two-year period (2010-2012). We used dynamic factor analysis to determine whether there were common patterns in growth rates within juveniles based on their natal region, capture location habitat type, and whether they were wild or of hatchery origin. We identified up to five large-scale trends in juvenile growth rates depending on month and year of capture. We also found that hatchery fish had a narrower range of trend loadings for some capture groups, suggesting that hatchery fish do not express the same breadth of growth variability as wild fish. However, we were unable to resolve a relationship between specific growth patterns and habitat transitions. Our study exemplifies how a relatively new statistical analysis can be applied to dating or aging techniques to summarize individual variation, and characterize aspects of life history diversity. PMID- 27695095 TI - The Prevalence of and Risk Factors Associated with Musculoskeletal Disorders among Sonographers in Central China: A Cross-Sectional Study. AB - OBJECTIVE: Studies from industrialized countries show that musculoskeletal disorders (MSD) occur commonly in sonographers. However, little is known about sonographers in China, where the awareness of ergonomics and MSD, workload, and available equipment/facilities may differ. We aimed to investigate the prevalence of MSD and associated risk factors in sonographers in central China. METHODS: A cross-sectional survey was conducted with 381 sonographers from 14 randomly selected tertiary hospitals in Hubei province, central China. Musculoskeletal symptoms (using the Nordic Questionnaire) and risk factors (mostly derived from the Health Benefit Trust survey instrument and the Dutch Musculoskeletal Questionnaire) were recorded. Multivariate logistic regression was used to quantify associations between risk factors and MSD. RESULTS: The 12-month period prevalence of MSD was 98.3%, being highest in the neck (93.5%) and shoulder (92.2%), followed by the lower back (83.2%), wrist/hand, upper back, and elbow. Factors contributing to neck pain were psychological fatigue, shoulder abduction and trunk bend-and-twist posture. Height-adjustable tables and chairs were protective factors. Shoulder pain was associated with female sex, health status, mental stress, shoulder abduction, and trunk bend-and-twist posture. Height adjustable chairs and the awareness of adjusting the workstation before scanning were protective factors. Elbow pain was associated with health status and height adjustable tables. Wrist/hand pain was associated with female sex, bending the wrist, and working with obese patients. Upper back pain was associated with shoulder abduction, height-adjustable chairs, and device location. Lower back pain was associated with the number of scans performed per day, awkward postures, bending the trunk, twisting or bending the neck forward, and using a footrest. CONCLUSIONS: This study suggests a high prevalence of MSD in sonographers in central China. Hence, it is necessary to improve the awareness of MSD by training, and the ergonomics of their current work environment by addressing physical workload, and psychological and equipment/facility-related factors. PMID- 27695097 TI - Minimal Residual Disease at First Achievement of Complete Remission Predicts Outcome in Adult Patients with Philadelphia Chromosome-Negative Acute Lymphoblastic Leukemia. AB - We evaluated the prognostic effect of minimal residual disease at first achievement of complete remission (MRD at CR1) in adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (ALL). A total of 97 patients received treatment in our center between 2007 and 2012 were retrospectively reviewed in this study. Patients were divided into two arms according to the post-remission therapy (chemotherapy alone or allogeneic hematopoietic stem cell transplantation (allo-HSCT)) they received. MRD was detected by four-color flow cytometry. We chose 0.02% and 0.2% as the cut-off points of MRD at CR1 for risk stratification using receiver operating characteristic analysis. The 3-year overall survival (OS) and leukemia free survival (LFS) rates for the whole cohort were 46.2% and 40.5%. MRD at CR1 had a significantly negative correlation with survival in both arms. Three-year OS rates in the chemotherapy arm were 70.0%, 25.2%, 0% (P = 0.003) for low, intermediate, and high levels of MRD at CR1, respectively. Three-year OS rates in the transplant arm were 81.8%, 64.3%, 27.3% (P = 0.005) for low, intermediate, and high levels of MRD at CR1, respectively. Multivariate analysis confirmed that higher level of MRD at CR1 was a significant adverse factor for OS and LFS. Compared with chemotherapy alone, allo-HSCT significantly improved LFS rates in patients with intermediate (P = 0.005) and high (P = 0.022) levels of MRD at CR1, but not patients with low level of MRD at CR1 (P = 0.851). These results suggested that MRD at CR1 could strongly predict the outcome of adult ALL. Patients with intermediate and high levels of MRD at CR1 would benefit from allo HSCT. PMID- 27695096 TI - Detection of Leptomeningeal Metastasis by Contrast-Enhanced 3D T1-SPACE: Comparison with 2D FLAIR and Contrast-Enhanced 2D T1-Weighted Images. AB - INTRODUCTION: To compare the diagnostic accuracy of contrast-enhanced 3D(dimensional) T1-weighted sampling perfection with application-optimized contrasts by using different flip angle evolutions (T1-SPACE), 2D fluid attenuated inversion recovery (FLAIR) images and 2D contrast-enhanced T1-weighted image in detection of leptomeningeal metastasis except for invasive procedures such as a CSF tapping. MATERIALS AND METHODS: Three groups of patients were included retrospectively for 9 months (from 2013-04-01 to 2013-12-31). Group 1 patients with positive malignant cells in CSF cytology (n = 22); group 2, stroke patients with steno-occlusion in ICA or MCA (n = 16); and group 3, patients with negative results on MRI, whose symptom were dizziness or headache (n = 25). A total of 63 sets of MR images are separately collected and randomly arranged: (1) CE 3D T1-SPACE; (2) 2D FLAIR; and (3) CE T1-GRE using a 3-Tesla MR system. A faculty neuroradiologist with 8-year-experience and another 2nd grade trainee in radiology reviewed each MR image- blinded by the results of CSF cytology and coded their observations as positives or negatives of leptomeningeal metastasis. The CSF cytology result was considered as a gold standard. Sensitivity and specificity of each MR images were calculated. Diagnostic accuracy was compared using a McNemar's test. A Cohen's kappa analysis was performed to assess inter observer agreements. RESULTS: Diagnostic accuracy was not different between 3D T1 SPACE and CSF cytology by both raters. However, the accuracy test of 2D FLAIR and 2D contrast-enhanced T1-weighted GRE was inconsistent by the two raters. The Kappa statistic results were 0.657 (3D T1-SPACE), 0.420 (2D FLAIR), and 0.160 (2D contrast-enhanced T1-weighted GRE). The 3D T1-SPACE images showed the highest inter-observer agreements between the raters. CONCLUSIONS: Compared to 2D FLAIR and 2D contrast-enhanced T1-weighted GRE, contrast-enhanced 3D T1 SPACE showed a better detection rate of leptomeningeal metastasis.

PMID- 27695098 TI - Regulation of Matrix Metalloproteinase-2 Activity by COX-2-PGE2-pAKT Axis Promotes Angiogenesis in Endometriosis. AB - Endometriosis is characterized by the ectopic development of the endometrium which relies on angiogenesis. Although studies have identified the involvement of different matrix metalloproteinases (MMPs) in endometriosis, no study has yet investigated the role of MMP-2 in endometriosis-associated angiogenesis. The present study aims to understand the regulation of MMP-2 activity in endothelial cells and on angiogenesis during progression of ovarian endometriosis. Histological and biochemical data showed increased expressions of vascular endothelial growth factor (VEGF), VEGF receptor-2, cycloxygenase (COX)-2, von Willebrand factor along with angiogenesis during endometriosis progression. Women with endometriosis showed decreased MMP-2 activity in eutopic endometrium as compared to women without endometriosis. However, ectopic ovarian endometrioma showed significantly elevated MMP-2 activity with disease severity. In addition, increased MT1MMP and decreased tissue inhibitors of metalloproteinases (TIMP)-2 expressions were found in the late stages of endometriosis indicating more MMP-2 activation with disease progression. In vitro study using human endothelial cells showed that prostaglandin E2 (PGE2) significantly increased MMP-2 activity as well as tube formation. Inhibition of COX-2 and/or phosphorylated AKT suppressed MMP-2 activity and endothelial tube formation suggesting involvement of PGE2 in regulation of MMP-2 activity during angiogenesis. Moreover, specific inhibition of MMP-2 by chemical inhibitor significantly reduced cellular migration, invasion and tube formation. In ovo assay showed decreased angiogenic branching upon MMP-2 inhibition. Furthermore, a significant reduction of lesion numbers was observed upon inhibition of MMP-2 and COX-2 in mouse model of endometriosis. In conclusion, our study establishes the involvement of MMP-2 activity via COX-2 PGE2-pAKT axis in promoting angiogenesis during endometriosis progression. PMID- 27695100 TI - Borrelia burgdorferi Induces TLR2-Mediated Migration of Activated Dendritic Cells in an Ex Vivo Human Skin Model. AB - Borrelia burgdorferi is transmitted into the skin of the host where it encounters and interacts with two dendritic cell (DC) subsets; Langerhans cells (LCs) and dermal DCs (DDCs). These cells recognize pathogens via pattern recognition receptors, mature and migrate out of the skin into draining lymph nodes, where they orchestrate adaptive immune responses. In order to investigate the response of skin DCs during the early immunopathogenesis of Lyme borreliosis, we injected B. burgdorferi intradermally into full-thickness human skin and studied the migration of DCs out of the skin, the activation profile and phenotype of migrated cells. We found a significant increase in the migration of LCs and DDCs in response to B. burgdorferi. Notably, migration was prevented by blocking TLR2. DCs migrated from skin inoculated with higher numbers of spirochetes expressed significantly higher levels of CD83 and produced pro-inflammatory cytokines. No difference was observed in the expression of HLA-DR, CD86, CD38, or CCR7. To conclude, we have established an ex vivo human skin model to study DC-B. burgdorferi interactions. Using this model, we have demonstrated that B. burgdorferi-induced DC migration is mediated by TLR2. Our findings underscore the utility of this model as a valuable tool to study immunity to spirochetal infections. PMID- 27695102 TI - Reflectance Prediction Modelling for Residual-Based Hyperspectral Image Coding. AB - A Hyperspectral (HS) image provides observational powers beyond human vision capability but represents more than 100 times the data compared to a traditional image. To transmit and store the huge volume of an HS image, we argue that a fundamental shift is required from the existing "original pixel intensity"-based coding approaches using traditional image coders (e.g., JPEG2000) to the "residual"-based approaches using a video coder for better compression performance. A modified video coder is required to exploit spatial-spectral redundancy using pixel-level reflectance modelling due to the different characteristics of HS images in their spectral and shape domain of panchromatic imagery compared to traditional videos. In this paper a novel coding framework using Reflectance Prediction Modelling (RPM) in the latest video coding standard High Efficiency Video Coding (HEVC) for HS images is proposed. An HS image presents a wealth of data where every pixel is considered a vector for different spectral bands. By quantitative comparison and analysis of pixel vector distribution along spectral bands, we conclude that modelling can predict the distribution and correlation of the pixel vectors for different bands. To exploit distribution of the known pixel vector, we estimate a predicted current spectral band from the previous bands using Gaussian mixture-based modelling. The predicted band is used as the additional reference band together with the immediate previous band when we apply the HEVC. Every spectral band of an HS image is treated like it is an individual frame of a video. In this paper, we compare the proposed method with mainstream encoders. The experimental results are fully justified by three types of HS dataset with different wavelength ranges. The proposed method outperforms the existing mainstream HS encoders in terms of rate-distortion performance of HS image compression.

However, genome-wide transcriptome patterns throughout maize endosperm development have not been comprehensively investigated to date. Accordingly, we performed a high-throughput RNA sequencing (RNA-seq) analysis of the maize endosperm transcriptome at 5, 10, 15 and 20 days after pollination (DAP). We found that more than 11,000 protein-coding genes underwent alternative splicing (AS) events during the four developmental stages studied. These genes were mainly involved in intracellular protein transport, signal transmission, cellular carbohydrate metabolism, cellular lipid metabolism, lipid biosynthesis, protein modification, histone modification, cellular amino acid metabolism, and DNA repair. Additionally, 7,633 genes, including 473 transcription factors (TFs), were differentially expressed among the four developmental stages. The differentially expressed TFs were from 50 families, including the bZIP, WRKY, GeBP and ARF families. Further analysis of the stage-specific TFs showed that binding, nucleus and ligand-dependent nuclear receptor activities might be important at 5 DAP, that immune responses, signalling, binding and lumen development are involved at 10 DAP, that protein metabolic processes and the cytoplasm might be important at 15 DAP, and that the responses to various stimuli are different at 20 DAP compared with the other developmental stages. This RNA seq analysis provides novel, comprehensive insights into the transcriptome dynamics during early endosperm development in maize.

AB - Understanding information coding is important for resolving the functions of visual neural circuits. The motion vision system is a classic model for studying information coding as it contains a concise and complete information-processing circuit. In Drosophila, the axon terminals of motion-detection neurons (T4 and T5) project to the lobula plate, which comprises four regions that respond to the four cardinal directions of motion. The lobula plate thus represents a topographic map on a transverse plane. This enables us to study the coding of diagonal motion by investigating its response pattern. By using in vivo two photon calcium imaging, we found that the axon terminals of T4 and T5 cells in the lobula plate were activated during diagonal motion. Further experiments showed that the response to diagonal motion is distributed over the following two regions compared to the cardinal directions of motion-a diagonal motion selective response region and a non-selective response region-which overlap with the response regions of the two vector-correlated cardinal directions of motion. Interestingly, the sizes of the non-selective response regions are linearly correlated with the angle of the diagonal motion. These results revealed that the Drosophila visual system employs a composite coding for diagonal motion that includes both independent coding and vector decomposition coding.

AB - OBJECTIVES: This paper presents a geographic information system (GIS)-based proximal area method and gravity method for identifying areas with physician shortages. The innovation of this paper is that it uses the appropriate methods to discover each type of health resource and then integrates all these methods to assess spatial access to health resources using population distribution data. In this way, spatial access to health resources for an entire city can be visualized in one neat package, which can help health policy makers quickly comprehend realistic distributions of health resources at a macro level. METHODS: First, classify health resources according to the trade areas of the patients they serve. Second, apply an appropriate method to each different type of health resource to measure spatial access to those resources. Third, integrate all types of access using population distribution data. RESULTS: In case study of Shanghai with the fusion method, areas with physician shortages are located primarily in suburban districts, especially in district junction areas. The result suggests that the government of Shanghai should pay more attention to these areas by investing in new or relocating existing health resources. CONCLUSION: The fusion method is demonstrated to be more accurate and practicable than using a single method to assess spatial access to health resources. PMID- 27695104 TI - Are Categorical Spatial Relations Encoded by Shifting Visual Attention between Objects? AB - Perceiving not just values, but relations between values, is critical to human cognition. We tested the predictions of a proposed mechanism for processing categorical spatial relations between two objects-the shift account of relation processing-which states that relations such as 'above' or 'below' are extracted by shifting visual attention upward or downward in space. If so, then shifts of attention should improve the representation of spatial relations, compared to a control condition of identity memory. Participants viewed a pair of briefly flashed objects and were then tested on either the relative spatial relation or identity of one of those objects. Using eye tracking to reveal participants' voluntary shifts of attention over time, we found that when initial fixation was on neither object, relational memory showed an absolute advantage for the object following an attention shift, while identity memory showed no advantage for either object. This result is consistent with the shift account of relation processing. When initial fixation began on one of the objects, identity memory strongly benefited this fixated object, while relational memory only showed a relative benefit for objects following an attention shift. This result is also consistent, although not as uniquely, with the shift account of relation processing. Taken together, we suggest that the attention shift account provides a mechanistic explanation for the overall results. This account can potentially serve as the common mechanism underlying both linguistic and perceptual representations of spatial relations. PMID- 27695106 TI - FMRP Associates with Cytoplasmic Granules at the Onset of Meiosis in the Human Oocyte. AB - Germ cell development and primordial follicle formation during fetal life is critical in establishing the pool of oocytes that subsequently determines the reproductive lifespan of women. Fragile X-associated primary ovarian insufficiency (FXPOI) is caused by inheritance of the FMR1 premutation allele and approximately 20% of women with the premutation allele develop ovarian dysfunction and premature ovarian insufficiency. However, the underlying disease mechanism remains obscure, and a potential role of FMRP in human ovarian development has not been explored. We have characterised the expression of FMR1 and FMRP in the human fetal ovary at the time of germ cell entry into meiosis through to primordial follicle formation. FMRP expression is exclusively in germ cells in the human fetal ovary. Increased FMRP expression in germ cells coincides with the loss of pluripotency-associated protein expression, and entry into meiosis is associated with FMRP granulation. In addition, we have uncovered FMRP association with components of P-bodies and stress granules, suggesting it may have a role in mRNA metabolism at the time of onset of meiosis. Therefore, this data support the hypothesis that FMRP plays a role regulating mRNAs during pivotal maturational processes in fetal germ cells, and ovarian dysfunction resulting from FMR1 premutation may have its origins during these stages of oocyte development. PMID- 27695108 TI - Mycorrhizal Fungal Diversity and Community Composition in Two Closely Related Platanthera (Orchidaceae) Species. AB - While it is generally acknowledged that orchid species rely on mycorrhizal fungi for completion of their life cycle, little is yet known about how mycorrhizal fungal diversity and community composition vary within and between closely related orchid taxa. In this study, we used 454 amplicon pyrosequencing to investigate variation in mycorrhizal communities between pure (allopatric) and mixed (sympatric) populations of two closely related Platanthera species (Platanthera bifolia and P. chlorantha) and putative hybrids. Consistent with previous research, the two species primarily associated primarily with members of the Ceratobasidiaceae and, to a lesser extent, with members of the Sebacinales and Tulasnellaceae. In addition, a large number of ectomycorrhizal fungi belonging to various families were observed. Although a considerable number of mycorrhizal fungi were common to both species, the fungal communities were significantly different between the two species. Individuals with intermediate morphology showed communities similar to P. bifolia, confirming previous results based on the genetic architecture and fragrance composition that putative hybrids essentially belonged to one of the parental species (P. bifolia). Differences in mycorrhizal communities between species were smaller in mixed populations than between pure populations, suggesting that variation in mycorrhizal communities was largely controlled by local environmental conditions. The small differences in mycorrhizal communities in mixed populations suggests that mycorrhizal fungi are most likely not directly involved in maintaining species boundaries between the two Platanthera species. However, seed germination experiments are needed to unambiguously assess the contribution of mycorrhizal divergence to reproductive isolation. PMID- 27695107 TI - Climate Change Influences on the Global Potential Distribution of the Mosquito Culex quinquefasciatus, Vector of West Nile Virus and Lymphatic Filariasis. AB - Rapid emergence of most vector-borne diseases (VBDs) may be associated with range expansion of vector populations. Culex quinquefasciatus Say 1823 is a potential vector of West Nile virus, Saint Louis encephalitis virus, and lymphatic filariasis. We estimated the potential distribution of Cx. quinquefasciatus under both current and future climate conditions. The present potential distribution of Cx. quinquefasciatus showed high suitability across low-latitude parts of the world, reflecting the current distribution of the species. Suitable conditions were identified also in narrow zones of North Africa and Western Europe. Model transfers to future conditions showed a potential distribution similar to that under present-day conditions, although with higher suitability in southern Australia. Highest stability with changing climate was between 30 degrees S and 30 degrees N. The areas present high agreement among diverse climate models as regards distributional potential in the future, but differed in anticipating potential for distribution in North and Central Africa, southern Asia, central USA, and southeastern Europe. Highest disparity in model predictions across representative concentration pathways (RCPs) was in Saudi Arabia and Europe. The model predictions allow anticipation of changing distributional potential of the species in coming decades. PMID- 27695109 TI - Blood Component Therapy and Coagulopathy in Trauma: A Systematic Review of the Literature from the Trauma Update Group. AB - BACKGROUND: Traumatic coagulopathy is thought to increase mortality and its treatment to reduce preventable deaths. However, there is still uncertainty in this field, and available literature results may have been overestimated. METHODS: We searched the MEDLINE database using the PubMed platform. We formulated four queries investigating the prognostic weight of traumatic coagulopathy defined according to conventional laboratory testing, and the effectiveness in reducing mortality of three different treatments aimed at contrasting coagulopathy (high fresh frozen plasma/packed red blood cells ratios, fibrinogen, and tranexamic acid administration). Randomized controlled trials were selected along with observational studies that used a multivariable approach to adjust for confounding. Strict criteria were adopted for quality assessment based on a two-step approach. First, we rated quality of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria. Then, this rating was downgraded if other three criteria were not met: high reporting quality according to shared standards, absence of internal methodological and statistical issues not detailed by the GRADE system, and absence of external validity issues. RESULTS: With few exceptions, the GRADE rating, reporting and methodological quality of observational studies was "very low", with frequent external validity issues. The only two randomized trials retrieved were, instead, of high quality. Only weak evidence was found for a relation between coagulopathy and mortality. Very weak evidence was found supporting the use of fibrinogen administration to reduce mortality in trauma. On the other hand, we found high evidence that the use of 1:1 vs. 1:2 high fresh frozen plasma/packed red blood cells ratios failed to obtain a 12% mortality reduction. This does not exclude lower mortality rates, which have not been investigated. The use of tranexamic acid in trauma was supported by "high" quality evidence according to the GRADE classification but was downgraded to "moderate" for external validity issues. CONCLUSIONS: Tranexamic acid is effective in reducing mortality in trauma. The other transfusion practices we investigated have been inadequately studied in the literature, as well as the independent association between mortality and coagulopathy measured with traditional laboratory testing. Overall, in this field of research literature quality is poor. PMID- 27695110 TI - Gender-Disparities in Adults with Type 1 Diabetes: More Than a Quality of Care Issue. A Cross-Sectional Observational Study from the AMD Annals Initiative. AB - We evaluated gender-differences in quality of type 1 diabetes (T1DM) care. Starting from electronic medical records of 300 centers, 5 process indicators, 3 favorable and 6 unfavorable intermediate outcomes, 6 treatment intensity/appropriateness measures and an overall quality score were measured. The likelihood of women vs. men (reference class) to be monitored, to reach outcomes, or to be treated has been investigated through multilevel logistic regression analyses; results are expressed as Odd Ratios (ORs) and 95% confidence intervals (95%CIs). The inter-center variability in the achievement of the unfavorable outcomes was also investigated. Overall, 28,802 subjects were analyzed (45.5% women). Women and men had similar age (44.5+/-16.0 vs. 45.0+/ 17.0 years) and diabetes duration (18.3+/-13.0 vs. 18.8+/-13.0 years). No between gender differences were found in process indicators. As for intermediate outcomes, women showed 33% higher likelihood of having HbA1c >=8.0% (OR = 1.33; 95%CI: 1.25-1.43), 29% lower risk of blood pressure >=140/90 mmHg (OR = 0.71; 95%CI: 0.65-0.77) and 27% lower risk of micro/macroalbuminuria (OR = 0.73; 95%CI: 0.65-0.81) than men, while BMI, LDL-c and GFR did not significantly differ; treatment intensity/appropriateness was not systematically different between genders; overall quality score was similar in men and women. Consistently across centers a larger proportion of women than men had HbA1c >=8.0%, while a smaller proportion had BP >=140/90 mmHg. No gender-disparities were found in process measures and improvements are required in both genders. The systematic worse metabolic control in women and worse blood pressure in men suggest that pathophysiologic differences rather than the care provided might explain these differences.

AB - Partially myristoylated chitosan pyrrolidone carboxylate (PMCP) is a cationic amphiphilic chitosan derivative. Glabridin (Glab) from licorice root extracts is a hydrophobic antimelanogenic agent. Here we assessed the effects of cationic Glab-containing polymeric micelles derived from PMCP (Glab/PMCP-PM) on the ability of Glab to penetrate the skin and inhibit melanogenesis using a human skin model. The amount of Glab absorbed 24 h after the application of Glab/PMCP PM was approximately four times higher than that of conventional oil-in-water micelles (control) prepared using Tween 60. Further, the release of IL-1alpha, a mediator of inflammation, was not detected. Treatment with Glab/PMCP-PM significantly increased the inhibition of melanogenesis compared with control. The inhibition of melanogenesis depends upon the enhanced ability of Glab to penetrate the skin, particularly the epidermis. Moreover, the inhibition of melanogenesis and the cationic potential of the Glab/PMCP-PM levels were increased by the cationic phospholipid copolymer. Therefore, Glab/PMCP-PM shows potential as an effective transdermal delivery system for treating skin hyperpigmentation. PMID- 27695111 TI - Constitutive Association of Tie1 and Tie2 with Endothelial Integrins is Functionally Modulated by Angiopoietin-1 and Fibronectin. AB - Functional cross-talk between Tie2 and Integrin signaling pathways is essential to coordinate endothelial cell adhesion and migration in response to the extracellular matrix, yet the mechanisms behind this phenomenon are unclear. Here, we examine the possibility that receptor cross-talk is driven through uncharacterized Tie-integrin interactions on the endothelial surface. Using a live cell FRET-based proximity assay, we monitor Tie-integrin receptor recognition and demonstrate that both Tie1 and Tie2 readily associate with integrins alpha5beta1 and alphaVbeta3 through their respective ectodomains. Although not required, Tie2-integrin association is significantly enhanced in the presence of the extracellular component and integrin ligand fibronectin. In vitro binding assays with purified components reveal that Tie-integrin recognition is direct, and further demonstrate that the receptor binding domain of the Tie2 ligand Ang-1, but not the receptor binding domain of Ang-2, can independently associate with alpha5beta1 or alphaVbeta3. Finally, we reveal that cooperative Tie/integrin interactions selectively stimulate ERK/MAPK signaling in the presence of both Ang-1 and fibronectin, suggesting a molecular mechanism to sensitize Tie2 to extracellular matrix. We provide a mechanistic model highlighting the role of receptor localization and association in regulating distinct signaling cascades and in turn, the angiogenic switch. PMID- 27695114 TI - A Pipelined Non-Deterministic Finite Automaton-Based String Matching Scheme Using Merged State Transitions in an FPGA. AB - This paper proposes a pipelined non-deterministic finite automaton (NFA)-based string matching scheme using field programmable gate array (FPGA) implementation. The characteristics of the NFA such as shared common prefixes and no failure transitions are considered in the proposed scheme. In the implementation of the automaton-based string matching using an FPGA, each state transition is implemented with a look-up table (LUT) for the combinational logic circuit between registers. In addition, multiple state transitions between stages can be performed in a pipelined fashion. In this paper, it is proposed that multiple one to-one state transitions, called merged state transitions, can be performed with an LUT. By cutting down the number of used LUTs for implementing state transitions, the hardware overhead of combinational logic circuits is greatly reduced in the proposed pipelined NFA-based string matching scheme. PMID- 27695113 TI - Increased Interstitial Concentrations of Glutamate and Pyruvate in Vastus Lateralis of Women with Fibromyalgia Syndrome Are Normalized after an Exercise Intervention - A Case-Control Study. AB - BACKGROUND: Fibromyalgia syndrome (FMS) is associated with central alterations, but controversies exist regarding the presence and role of peripheral factors. Microdialysis (MD) can be used in vivo to study muscle alterations in FMS. Furthermore for chronic pain conditions such as FMS, the mechanisms for the positive effects of exercise are unclear. This study investigates the interstitial concentrations of algesics and metabolites in the vastus lateralis muscle of 29 women with FMS and 28 healthy women before and after an exercise intervention. METHODS: All the participants went through a clinical examination and completed a questionnaire. In addition, their pressure pain thresholds (PPTs) in their upper and lower extremities were determined. For both groups, MD was conducted in the vastus lateralis muscle before and after a 15-week exercise intervention of mainly resistance training of the lower limbs. Muscle blood flow and interstitial muscle concentrations of lactate, pyruvate, glutamate, glucose, and glycerol were determined. RESULTS: FMS was associated with significantly increased interstitial concentrations of glutamate, pyruvate, and lactate. After the exercise intervention, the FMS group exhibited significant decreases in pain intensity and in mean interstitial concentrations of glutamate, pyruvate, and glucose. The decrease in pain intensity in FMS correlated significantly with the decreases in pyruvate and glucose. In addition, the FMS group increased their strength and endurance. CONCLUSION: This study supports the suggestion that peripheral metabolic and algesic muscle alterations are present in FMS patients and that these alterations contribute to pain. After an exercise intervention, alterations normalized, pain intensity decreased (but not abolished), and strength and endurance improved, all findings that suggest the effects of exercise are partially peripheral. PMID- 27695116 TI - Characterization and Expression Analysis of Phytoene Synthase from Bread Wheat (Triticum aestivum L.). AB - Phytoene synthase (PSY) regulates the first committed step of the carotenoid biosynthetic pathway in plants. The present work reports identification and characterization of the three PSY genes (TaPSY1, TaPSY2 and TaPSY3) in wheat (Triticum aestivum L.). The TaPSY1, TaPSY2, and TaPSY3 genes consisted of three homoeologs on the long arm of group 7 chromosome (7L), short arm of group 5 chromosome (5S), and long arm of group 5 chromosome (5L), respectively in each subgenomes (A, B, and D) with a similarity range from 89% to 97%. The protein sequence analysis demonstrated that TaPSY1 and TaPSY3 retain most of conserved motifs for enzyme activity. Phylogenetic analysis of all TaPSY revealed an evolutionary relationship among PSY proteins of various monocot species. TaPSY derived from A and D subgenomes shared proximity to the PSY of Triticum urartu and Aegilops tauschii, respectively. The differential expression of TaPSY1, TaPSY2, and TaPSY3 in the various tissues, seed development stages, and stress treatments suggested their role in plant development, and stress condition. TaPSY3 showed higher expression in all tissues, followed by TaPSY1. The presence of multiple stress responsive cis-regulatory elements in promoter region of TaPSY3 correlated with the higher expression during drought and heat stresses has suggested their role in these conditions. The expression pattern of TaPSY3 was correlated with the accumulation of beta-carotene in the seed developmental stages. Bacterial complementation assay has validated the functional activity of each TaPSY protein. Hence, TaPSY can be explored in developing genetically improved wheat crop. PMID- 27695115 TI - Comparison of the Ability of Different Clinical Treatment Scores to Estimate Prognosis in High-Risk Early Breast Cancer Patients: A Hellenic Cooperative Oncology Group Study. AB - BACKGROUND-AIM: Early breast cancer is a heterogeneous disease, and, therefore, prognostic tools have been developed to evaluate the risk for distant recurrence. In the present study, we sought to develop a risk for recurrence score (RRS) based on mRNA expression of three proliferation markers in high-risk early breast cancer patients and evaluate its ability to predict risk for relapse and death. In addition the Adjuvant! Online score (AOS) was also determined for each patient, providing a 10-year estimate of relapse and mortality risk. We then evaluated whether RRS or AOS might possibly improve the prognostic information of the clinical treatment score (CTS), a model derived from clinicopathological variables. METHODS: A total of 1,681 patients, enrolled in two prospective phase III trials, were treated with anthracycline-based adjuvant chemotherapy. Sufficient RNA was extracted from 875 samples followed by multiplex quantitative reverse transcription-polymerase chain reaction for assessing RACGAP1, TOP2A and Ki67 mRNA expression. The CTS, slightly modified to fit our cohort, integrated the prognostic information from age, nodal status, tumor size, histological grade and treatment. Patients were also classified to breast cancer subtypes defined by immunohistochemistry. Likelihood ratio (LR) tests and concordance indices were used to estimate the relative increase in the amount of information provided when either RRS or AOS is added to CTS. RESULTS: The optimal RRS, in terms of disease free survival (DFS) and overall survival (OS), was based on the co-expression of two of the three evaluated genes (RACGAP1 and TOP2A). CTS was prognostic for DFS (p<0.001), while CTS, AOS and RRS were all prognostic for OS (p<0.001, p<0.001 and p = 0.036, respectively). The use of AOS in addition to CTS added prognostic information regarding DFS (LR-Deltachi2 8.7, p = 0.003), however the use of RRS in addition to CTS did not. For estimating OS, the use of either AOS or RRS in addition to CTS added significant prognostic information. Specifically, the use of both CTS and AOS had significantly better prognostic value vs. CTS alone (LR Deltachi2 20.8, p<0.001), as well as the use of CTS and RRS vs. CTS alone (LR Deltachi2 4.8, p = 0.028). Additionally, more patients were scored as high-risk by AOS than CTS. According to immunohistochemical subtypes, prognosis was improved in the Luminal A (LR-Deltachi2 7.2, p = 0.007) and Luminal B (LR Deltachi2 8.3, p = 0.004) subtypes, in HER2-negative patients (LR-Deltachi2 23.4, p<0.001) and in patients with >3 positive nodes (LR-Deltachi2 23.9, p<0.001) when AOS was added to CTS. CONCLUSIONS: The current study has shown a clear benefit in predicting overall survival of high-risk early breast cancer patients when combining CTS with either AOS or RRS. The combination of CTS and AOS adds significant prognostic information compared to CTS alone for DFS, while the combination of CTS with either AOS or RRS has better prognostic value than CTS alone for OS. These findings could possibly add on the information needed for the best risk prediction strategy in high-risk early breast cancer patients in a rather simple and inexpensive way, especially in Luminal A and B subtypes, HER2 negative patients and those with >3 positive nodes. PMID- 27695117 TI - Observation of Influence of Cataract Surgery on the Ocular Surface. AB - INTRODUCTION: To evaluate meibomian gland function, changes of lacrimal tears and ocular surface parameters and tear inflammatory mediators following cataract surgery. METHODS: 48 eyes of 34 patients who underwent uncomplicated phacoemulsification were involved and divided into 2 groups with those who had preexisting dry-eye before cataract surgery and those who did not. Ocular symptom score, Schirmer I test, tear film break-up time (TBUT), corneal sensitivity threshold, corneal staining, inflammatory cytokine activities, lid margin abnormalities, meibum expressibility, meibum quality and meibomian gland imaging were evaluated preoperatively, at 1 day, 1 and 2 months postoperatively. RESULTS: Ocular symptom scores were worse at 1 and 2 months postoperatively but, TBUT, corneal staining score and corneal sensitivity threshold showed gradual improvements at 1 month and 2 months postoperatively (p<0.05, respectively). Interestingly there were statistically significant improvements in TBUT, corneal staining score and corneal sensitivity threshold at 1 month postoperatively when topical eye drops were used compared to the period without topical therapy which is the months 2 postoperatively. There were statistically significant decreases in IL-1beta, IL-6, IL-8, MCP-1, TNF-alpha and IFN-gamma concentrations at 1 and 2 months postoperatively. Lid margin abnormalities, meibum quality and expressibility scores increased significantly (p < 0.05, respectively) at postoperative period. Compared with the no dry eye group, dry eye group revealed significantly higher ocular symptom scores, lower TBUT, higher lid margin abnormalities, meibum quality and expressibility scores after cataract surgery. There were significant correlations between IL-6 and parameters of dry eye, and between MGD parameters and ocular symptom scores. CONCLUSIONS: Our study revealed that meibomian gland function is influenced after cataract surgery accompanying structural changes and these were correlated with increased ocular symptom scores. Therefore, it could elucidate the development of dry eye related to cataract surgery. PMID- 27695118 TI - High Coverage and Utilization of Fortified Take-Home Rations among Children 6-35 Months of Age Provided through the Integrated Child Development Services Program: Findings from a Cross-Sectional Survey in Telangana, India. AB - The Integrated Child Development Services (ICDS) in the State of Telangana, India, freely provides a fortified complementary food product, Bal Amrutham, as a take-home ration to children 6-35 months of age. In order to understand the potential for impact of any intervention, it is essential to assess coverage and utilization of the program and to address the barriers to its coverage and utilization. A two-stage, stratified cross-sectional cluster survey was conducted to estimate the coverage and utilization of Bal Amrutham and to identify their barriers and drivers. In randomly selected catchment areas of ICDS centers, children under 36 months of age were randomly selected. A questionnaire, constructed from different validated and standard modules and designed to collect coverage data on nutrition programs, was administered to caregivers. A total of 1,077 children were enrolled in the survey. The coverage of the fortified take home ration was found to be high among the target population. Nearly all caregivers (93.7%) had heard of Bal Amrutham and 86.8% had already received the product for the target child. Among the children surveyed, 57.2% consumed the product regularly. The ICDS program's services were not found to be a barrier to product coverage. In fact, the ICDS program was found to be widely available, accessible, accepted, and utilized by the population in both urban and rural catchment areas, as well as among poor and non-poor households. However, two barriers to optimal coverage were found: the irregular supply of the product to the beneficiaries and the intra-household sharing of the product. Although sharing was common, the product was estimated to provide the target children with significant proportions of the daily requirements of macro- and micronutrients. Bal Amrutham is widely available, accepted, and consumed among the target population in the catchment areas of ICDS centers. The coverage of the product could be further increased by improving the supply chain. PMID- 27695119 TI - The Acute Effects of Interval-Type Exercise on Glycemic Control in Type 2 Diabetes Subjects: Importance of Interval Length. A Controlled, Counterbalanced, Crossover Study. AB - : Interval-type exercise is effective for improving glycemic control, but the optimal approach is unknown. The purpose of this study was to determine the importance of the interval length on changes in postprandial glycemic control following a single exercise bout. Twelve subjects with type 2 diabetes completed a cross-over study with three 1-hour interventions performed in a non-randomized but counter-balanced order: 1) Interval walking consisting of repeated cycles of 3 min slow (aiming for 54% of Peak oxygen consumption rate [VO2peak]) and 3 min fast (aiming for 89% of VO2peak) walking (IW3); 2) Interval walking consisting of repeated cycles of 1 min slow and 1 min fast walking (IW1) and 3) No walking (CON). The exercise interventions were matched with regards to walking speed, and VO2 and heart rate was assessed throughout all interventions. A 4-hour liquid mixed meal tolerance test commenced 30 min after each intervention, with blood samples taken regularly. IW3 and IW1 resulted in comparable mean VO2 and heart rates. Overall mean postprandial blood glucose levels were lower after IW3 compared to CON (10.3+/-3.0 vs. 11.1+/-3.3 mmol/L; P < 0.05), with no significant differences between IW1 (10.5+/-2.8 mmol/L) and CON or IW3 and IW1 (P > 0.05 for both). Conversely blood glucose levels at specific time points during the MMTT differed significantly following both IW3 and IW1 as compared to CON. Our findings support the previously found blood glucose lowering effect of IW3 and suggest that reducing the interval length, while keeping the walking speed and time spend on fast and slow walking constant, does not result in additional improvements. TRIAL REGISTRATION: ClinicalTrials.gov NCT02257190. PMID- 27695120 TI - An Exploration of Human Well-Being Bundles as Identifiers of Ecosystem Service Use Patterns. AB - We take a social-ecological systems perspective to investigate the linkages between ecosystem services and human well-being in South Africa. A recent paper identified different types of social-ecological systems in the country, based on distinct bundles of ecosystem service use. These system types were found to represent increasingly weak direct feedbacks between nature and people, from rural "green-loop" communities to urban "red-loop" societies. Here we construct human well-being bundles and explore whether the well-being bundles can be used to identify the same social-ecological system types that were identified using bundles of ecosystem service use. Based on national census data, we found three distinct well-being bundle types that are mainly characterized by differences in income, unemployment and property ownership. The distribution of these well-being bundles approximates the distribution of ecosystem service use bundles to a substantial degree: High levels of income and education generally coincided with areas characterised by low levels of direct ecosystem service use (or red-loop systems), while the majority of low well-being areas coincided with medium and high levels of direct ecosystem service use (or transition and green-loop systems). However, our results indicate that transformations from green-loop to red-loop systems do not always entail an immediate improvement in well-being, which we suggest may be due to a time lag between changes in the different system components. Using human well-being bundles as an indicator of social-ecological dynamics may be useful in other contexts since it is based on socio-economic data commonly collected by governments, and provides important insights into the connections between ecosystem services and human well-being at policy-relevant sub-national scales. PMID- 27695121 TI - The Potential of Class II Bacteriocins to Modify Gut Microbiota to Improve Host Health. AB - Production of bacteriocins is a potential probiotic feature of many lactic acid bacteria (LAB) as it can help prevent the growth of pathogens in gut environments. However, knowledge on bacteriocin producers in situ and their function in the gut of healthy animals is still limited. In this study, we investigated five bacteriocin-producing strains of LAB and their isogenic non producing mutants for probiotic values. The LAB bacteriocins, sakacin A (SakA), pediocin PA-1 (PedPA-1), enterocins P, Q and L50 (enterocins), plantaricins EF and JK (plantaricins) and garvicin ML (GarML), are all class II bacteriocins, but they differ greatly from each other in terms of inhibition spectrum and physicochemical properties. The strains were supplemented to mice through drinking water and changes on the gut microbiota composition were interpreted using 16S rRNA gene analysis. In general, we observed that overall structure of the gut microbiota remained largely unaffected by the treatments. However, at lower taxonomic levels, some transient but advantageous changes were observed. Some potentially problematic bacteria were inhibited (e.g., Staphylococcus by enterocins, Enterococcaceae by GarML, and Clostridium by plantaricins) and the proportion of LAB was increased in the presence of SakA-, plantaricins- and GarML producing bacteria. Moreover, the treatment with GarML-producing bacteria co occurred with decreased triglyceride levels in the host mice. Taken together, our results indicate that several of these bacteriocin producers have potential probiotic properties at diverse levels as they promote favorable changes in the host without major disturbance in gut microbiota, which is important for normal gut functioning.

AB - We hypothesized that tissue-resident macrophages in familial amyloid polyneuropathy (FAP) patients will exhibit qualitative or quantitative abnormalities, that may accelerate transthyretin (TTR)-derived amyloid deposition. To evaluate this, we examined the number and subset of tissue resident macrophages in heart tissue from amyloid-deposited FAP and control patients. In both FAP and control patients, tissue-resident macrophages in heart tissue were all Iba+/CD163+/CD206+ macrophages. However, the number of macrophages was significantly decreased in FAP patients compared with control patients. Furthermore, the proportion of intracellular TTR in CD14+ monocytes was reduced in peripheral blood compared with healthy donors. Based on these results, we next examined degradation and endocytosis of TTR in human induced pluripotent stem (iPS) cell-derived myeloid lineage cells (MLs), which function like macrophages. iPS-MLs express CD163 and CD206, and belong to the inhibitory macrophage category. In addition, iPS-MLs degrade both native and aggregated TTR in a cell-dependent manner in vitro. Further, iPS-MLs endocytose aggregated, and especially polymerized, TTR. These results suggest that decreased tissue localized macrophages disrupt clearance of TTR-derived amyloid deposits, leading to progression of a pathological condition in FAP patients. To improve this situation, clinical application of pluripotent stem cell-derived MLs may be useful as an approach for FAP therapy.

AB - The bioavailability, tissue distribution and metabolic fate of the major tea polyphenols, catechins and theaflavins as well as their gallated derivatives are yet to be precisely elucidated on a single identification platform for assessment of their relative bioefficacy in vivo. This is primarily due to the lack of suitable analytical tools for their simultaneous determination especially in an in vivo setting, which continues to constrain the evaluation of their relative health beneficiary potential and therefore prospective therapeutic application. Herein, we report a rapid and sensitive Ultra-Performance Liquid Chromatography Tandem Mass Spectrometry (UPLC-MS/MS) based method for the simultaneous determination of the major catechins and theaflavins in black tea infusions as well as in different vital tissues and body fluids of tea-consuming guinea pigs. This method allowed efficient separation of all polyphenols within seven minutes of chromatographic run and had a lower limit of quantification (LLOQ) of ~5 ng/ml. Using this method, almost all bioactive catechins and theaflavins could be simultaneously detected in the plasma of guinea pigs orally administered 5% black tea for 14 days. Our method could further detect the majority of these polyphenols in the lung and kidney as well as identify the major catechin metabolites in the urine of the tea-consuming animals. Overall, our study presents a novel tool for simultaneous detection and quantitation of both catechins and theaflavins in a single detection platform that could potentially enable precise elucidation of their relative bioavailability and bioefficacy as well as true health beneficiary potential in vivo. Such information would ultimately facilitate the accurate designing of therapeutic strategies utilizing high efficacy formulations of tea polyphenols for effective mitigation of oxidative damage and inflammation in humans as well as prevention of associated diseases.

AB - The anterior and intermediate lobes of the pituitary gland develop through invagination of the oral ectoderm and as they are endocrine tissues, they participate in the maintenance of vital functions via the synthesis and secretion of numerous hormones. We recently observed that several extrapituitary cells invade the anterior lobe of the developing pituitary gland. This raised the question of the origin(s) of these S100beta-positive cells, which are not classic endocrine cells but instead comprise a heterogeneous cell population with plural roles, especially as stem/progenitor cells. To better understand the roles of these S100beta-positive cells, we performed immunohistochemical analysis using several markers in S100beta/GFP-TG rats, which express GFP in S100beta-expressing cells under control of the S100beta promoter. GFP-positive cells were present as mesenchymal cells surrounding the developing pituitary gland and at Atwell's recess but were not present in the anterior lobe on embryonic day 15.5. These cells were negative for SOX2, a pituitary stem/progenitor marker, and PRRX1, a mesenchyme and pituitary stem/progenitor marker. However, three days later, GFP positive and PRRX1-positive (but SOX2-negative) cells were observed in the parenchyma of the anterior lobe. Furthermore, some GFP-positive cells were positive for vimentin, p75, isolectin B4, DESMIN, and Ki67. These data suggest that S100beta-positive cells of extrapituitary origin invade the anterior lobe, undergoing proliferation and diverse transformation during pituitary organogenesis. PMID- 27695126 TI - Simultaneous Maximum-Likelihood Reconstruction of Absorption Coefficient, Refractive Index and Dark-Field Scattering Coefficient in X-Ray Talbot-Lau Tomography. AB - A maximum-likelihood reconstruction technique for X-ray Talbot-Lau tomography is presented. This technique allows the iterative simultaneous reconstruction of discrete distributions of absorption coefficient, refractive index and a dark field scattering coefficient. This technique avoids prior phase retrieval in the tomographic projection images and thus in principle allows reconstruction from tomographic data with less than three phase steps per projection. A numerical phantom is defined which is used to evaluate convergence of the technique with regard to photon statistics and with regard to the number of projection angles and phase steps used. It is shown that the use of a random phase sampling pattern allows the reconstruction even for the extreme case of only one single phase step per projection. The technique is successfully applied to measured tomographic data of a mouse. In future, this reconstruction technique might also be used to implement enhanced imaging models for X-ray Talbot-Lau tomography. These enhancements might be suited to correct for example beam hardening and dispersion artifacts and improve overall image quality of X-ray Talbot-Lau tomography. PMID- 27695125 TI - Synthesis, Pharmacological Profile and Docking Studies of New Sulfonamides Designed as Phosphodiesterase-4 Inhibitors. AB - Prior investigations showed that increased levels of cyclic AMP down-regulate lung inflammatory changes, stimulating the interest in phosphodiesterase (PDE)4 as therapeutic target. Here, we described the synthesis, pharmacological profile and docking properties of a novel sulfonamide series (5 and 6a-k) designed as PDE4 inhibitors. Compounds were screened for their selectivity against the four isoforms of human PDE4 using an IMAP fluorescence polarized protocol. The effect on allergen- or LPS-induced lung inflammation and airway hyper-reactivity (AHR) was studied in A/J mice, while the xylazine/ketamine-induced anesthesia test was employed as a behavioral correlate of emesis in rodents. As compared to rolipram, the most promising screened compound, 6a (LASSBio-448) presented a better inhibitory index concerning PDE4D/PDE4A or PDE4D/PDE4B. Accordingly, docking analyses of the putative interactions of LASSBio-448 revealed similar poses in the active site of PDE4A and PDE4C, but slight unlike orientations in PDE4B and PDE4D. LASSBio-448 (100 mg/kg, oral), 1 h before provocation, inhibited allergen induced eosinophil accumulation in BAL fluid and lung tissue samples. Under an interventional approach, LASSBio-448 reversed ongoing lung eosinophilic infiltration, mucus exacerbation, peribronchiolar fibrosis and AHR by allergen provocation, in a mechanism clearly associated with blockade of pro-inflammatory mediators such as IL-4, IL-5, IL-13 and eotaxin-2. LASSBio-448 (2.5 and 10 mg/kg) also prevented inflammation and AHR induced by LPS. Finally, the sulfonamide derivative was shown to be less pro-emetic than rolipram and cilomilast in the assay employed. These findings suggest that LASSBio-448 is a new PDE4 inhibitor with marked potential to prevent and reverse pivotal pathological features of diseases characterized by lung inflammation, such as asthma. PMID- 27695128 TI - Correlation between Serum Lipid Levels and Measured Glomerular Filtration Rate in Chinese Patients with Chronic Kidney Disease. AB - INTRODUCTION: Dyslipidemia is often detected in patients with chronic kidney disease (CKD). Previous studies of the relationship between lipid profiles and kidney function have yielded variable results. We aimed to investigate the correlation between serum lipid levels and kidney function evaluated by measured glomerular filtration rate (mGFR) in Chinese patients with CKD. METHODS: A cross sectional study was conducted on 2036 Chinese CKD patients who had mGFR. Linear regression analysis was performed to evaluate the correlation between different serum lipid levels and mGFR, while logistic regression analysis was used to investigate the association between CKD stages and the risk of different types of dyslipidemia. RESULTS: The mean age was 55 years and the mean mGFR was 63 mL/min/1.73m2. After adjusting for some confounders (age, gender, body mass index, a history of diabetes, fasting glucose, a history of hypertension, systolic blood pressure, diastolic blood pressure, smoking status, hemoglobin, serum potassium, serum albumin, and serum uric acid), serum triglyceride level showed a negative correlation with mGFR (beta = -0.006, P = 0.006) in linear regression analysis, and CKD stages were positively related to the risk of hypertriglyceridemia (odds ratios were 1.329, 1.868, 2.514 and P were 0.046, < 0.001, < 0.001 for CKD stage 2, 3, 4/5, respectively) in logistic regression anlysis. CONCLUSIONS: Serum triglyceride level is independently association with mGFR. Patients with reduced kidney function are more likely to have higher serum triglyceride levels. Further longitudinal, multicenter and well-conducted studies are needed to provide more evidence. PMID- 27695127 TI - Respiratory Syncytial Virus-Infected Mesenchymal Stem Cells Regulate Immunity via Interferon Beta and Indoleamine-2,3-Dioxygenase. AB - Respiratory syncytial virus (RSV) has been reported to infect human mesenchymal stem cells (MSCs) but the consequences are poorly understood. MSCs are present in nearly every organ including the nasal mucosa and the lung and play a role in regulating immune responses and mediating tissue repair. We sought to determine whether RSV infection of MSCs enhances their immune regulatory functions and contributes to RSV-associated lung disease. RSV was shown to replicate in human MSCs by fluorescence microscopy, plaque assay, and expression of RSV transcripts. RSV-infected MSCs showed differentially altered expression of cytokines and chemokines such as IL-1beta, IL6, IL-8 and SDF-1 compared to epithelial cells. Notably, RSV-infected MSCs exhibited significantly increased expression of IFN beta (~100-fold) and indoleamine-2,3-dioxygenase (IDO) (~70-fold) than in mock infected MSCs. IDO was identified in cytosolic protein of infected cells by Western blots and enzymatic activity was detected by tryptophan catabolism assay. Treatment of PBMCs with culture supernatants from RSV-infected MSCs reduced their proliferation in a dose dependent manner. This effect on PBMC activation was reversed by treatment of MSCs with the IDO inhibitors 1-methyltryptophan and vitamin K3 during RSV infection, a result we confirmed by CRISPR/Cas9-mediated knockout of IDO in MSCs. Neutralizing IFN-beta prevented IDO expression and activity. Treatment of MSCs with an endosomal TLR inhibitor, as well as a specific inhibitor of the TLR3/dsRNA complex, prevented IFN-beta and IDO expression. Together, these results suggest that RSV infection of MSCs alters their immune regulatory function by upregulating IFN-beta and IDO, affecting immune cell proliferation, which may account for the lack of protective RSV immunity and for chronicity of RSV-associated lung diseases such as asthma and COPD. PMID- 27695129 TI - Revisiting the Phylogeny of the Animal Formins: Two New Subtypes, Relationships with Multiple Wing Hairs Proteins, and a Lost Human Formin. AB - Formins are a widespread family of eukaryotic cytoskeleton-organizing proteins. Many species encode multiple formin isoforms, and for animals, much of this reflects the presence of multiple conserved subtypes. Earlier phylogenetic analyses identified seven major formin subtypes in animals (DAAM, DIAPH, FHOD, FMN, FMNL, INF, and GRID2IP/delphilin), but left a handful of formins, particularly from nematodes, unassigned. In this new analysis drawing from genomic data from a wider range of taxa, nine formin subtypes are identified that encompass all the animal formins analyzed here. Included in this analysis are Multiple Wing Hairs proteins (MWH), which bear homology to formin N-terminal domains. Originally identified in Drosophila melanogaster and other arthropods, MWH-related proteins are also identified here in some nematodes (including Caenorhabditis elegans), and are shown to be related to a novel MWH-related formin (MWHF) subtype. One surprising result of this work is the discovery that a family of pleckstrin homology domain-containing formins (PHCFs) is represented in many vertebrates, but is strikingly absent from placental mammals. Consistent with a relatively recent loss of this formin, the human genome retains fragments of a defunct homologous formin gene. PMID- 27695130 TI - Cost-Effectiveness Analysis of Test-Based versus Presumptive Treatment of Uncomplicated Malaria in Children under Five Years in an Area of High Transmission in Central Ghana. AB - BACKGROUND: The presumptive approach of confirming malaria in health facilities leads to over-diagnosis of malaria, over use of anti-malaria drugs and the risk of drug resistance development. WHO recommends parasitological confirmation before treatment with artemisinin-based combination therapy (ACT) in all suspected malaria patients. The use of malaria rapid diagnostic tests (mRDTs) would make it possible for prescribers to diagnose malaria at point-of-care and better target the use of antimalarials. Therefore, a cost-effectiveness analysis was performed on the introduction of mRDTs for management of malaria in under five children in a high transmission area in Ghana where presumptive diagnosis was the norm in public health centres. METHODS: A cluster-randomised controlled trial where thirty-two health centres were randomised into test-based diagnosis of malaria using mRDTs (intervention) or clinical judgement (control) was used to measure the effect of mRDTs on appropriate treatment: 'a child with a positive reference diagnosis prescribed a course of ACT or a child with a negative reference diagnosis not given an ACT'. Cost data was collected from five purposively selected health centres and used to estimate the health sector costs of performing an mRDT and treat children for malaria and other common febrile illnesses. Costs of training healthcare personnel and supervision in the study period were also collected. A sample of caregivers to children participating in the trial was interviewed about household cost incurred on transport, drugs, fees, and special food during a period of one week after the health centre visit as well as days unable to work. A decision model approach was used to calculate the incremental cost-effectiveness ratios (ICERs). Univariate and multivariate sensitivity analyses were applied to assess the robustness of ICERs. RESULTS: The availability of mRDTs for malaria diagnosis resulted in fewer ACT treatments compared to the clinical judgement approach (73% versus 81%) and more children appropriately treated (70% versus 57%). The introduction of mRDT-based diagnosis would cost the Ministry of Health US$18.6 per extra appropriately treated child under five compared to clinical judgement while the ICER from a societal perspective was lower at US$11.0 per appropriately treated child. ICERs were sensitive to a decrease in adherence to negative mRDTs, malaria positivity rate and specificity of the mRDT. CONCLUSION: The introduction of mRDTs is likely to be considered cost-effective in this high transmission setting as this intervention increased the number of appropriately treated children at low cost.

AB - A novel Model Predictive Control (MPC) law for an Artificial Pancreas (AP) to automatically deliver insulin to people with type 1 diabetes is proposed. The MPC law is an enhancement of the authors' zone-MPC approach that has successfully been trialled in-clinic, and targets the safe outpatient deployment of an AP. The MPC law controls blood-glucose levels to a diurnally time-dependent zone, and enforces diurnal, hard input constraints. The main algorithmic novelty is the use of asymmetric input costs in the MPC problem's objective function. This improves safety by facilitating the independent design of the controller's responses to hyperglycemia and hypoglycemia. The proposed controller performs predictive pump suspension in the face of impending hypoglycemia, and subsequent predictive pump resumption, based only on clinical needs and feedback. The proposed MPC strategy's benefits are demonstrated by in-silico studies as well as highlights from a US Food and Drug Administration approved clinical trial in which 32 subjects each completed two 25 hour closed-loop sessions employing the proposed MPC law. PMID- 27695132 TI - Rough Gold Electrodes for Decreasing Impedance at the Electrolyte/Electrode Interface. AB - Electrode polarization at the electrolyte/electrode interface is often undesirable for bio-sensing applications, where charge accumulated over an electrode at constant potential causes large potential drop at the interface and low measurement sensitivity. In this study, novel rough electrodes were developed for decreasing electrical impedance at the interface. The electrodes were fabricated using electrochemical deposition of gold and sintering of gold nanoparticles. The performances of the gold electrodes were compared with platinum black electrodes. A constant phase element model was used to describe the interfacial impedance. Hundred folds of decrease in interfacial impedance were observed for fractal gold electrodes and platinum black. Biotoxicity, contact angle, and surface morphology of the electrodes were investigated. Relatively low toxicity and hydrophilic nature of the fractal and granulated gold electrodes make them suitable for bioimpedance and cell electromanipulation studies compared to platinum black electrodes which are both hydrophobic and toxic. PMID- 27695133 TI - Bromomethane Contamination in the Cathode of Proton Exchange Membrane Fuel Cells. AB - The effects of bromomethane (BrCH3), an airborne contaminant, on the performance of a single PEMFC are compared with that of another halocarbon, chlorobenzene. Under a constant current of 1 A cm-2 and at 45 degrees C, 20 ppm bromomethane causes approximately 30% cell voltage loss in approximately 30 h, as opposed to much more rapid performance degradation observed with chlorobenzene. Electrochemical impedance spectroscopy, cyclic voltammetry, linear scanning voltammetry, and polarization measurements are applied to characterize the temporary electrochemical reaction effect and permanent performance effects. X ray absorption spectroscopy is used to confirm that Br is adsorbed on the Pt electrocatalyst surface. We conclude that airborne bromomethane poisons a PEMFC in a different way from chlorobenzene because it is largely hydrolyzed to bromide, Br-, which is then excluded from the Pt catalyst by the negatively charged Nafion ionomer. The little Br- and bromomethane that adsorbs on the Pt surface can be partially removed by cycling but causes some irreversible surface area loss. PMID- 27695135 TI - A finite deformation model of planar serpentine interconnects for stretchable electronics. AB - Lithographically defined interconnects with filamentary, serpentine configurations have been widely used in various forms of stretchable electronic devices, owing to the ultra-high stretchability that can be achieved and the relative simple geometry that facilitates the design and fabrication. Theoretical models of serpentine interconnects developed previously for predicting the performance of stretchability were mainly based on the theory of infinitesimal deformation. This assumption, however, does not hold for the interconnects that undergo large levels of deformations before the structural failure. Here, an analytic model of serpentine interconnects is developed starting from the finite deformation theory of planar, curved beams. Finite element analyses (FEA) of the serpentine interconnects with a wide range of geometric parameters were performed to validate the developed model. Comparisons of the predicted stretchability to the estimations of linear models provide quantitative insights into the effect of finite deformation. Both the theoretical and numerical results indicate that a considerable overestimation (e.g., > 50% relatively) of the stretchability can be induced by the linear model for many representative shapes of serpentine interconnects. Furthermore, a simplified analytic solution of the stretchability is obtained by using an approximate model to characterize the nonlinear effect. The developed models can be used to facilitate the designs of serpentine interconnects in future applications.

AB - From a social disorganization standpoint, neighborhood residential instability potentially brings negative consequences to parent-child relationship qualities, but family social support and racial/ethnic identity may modify this association. Using data (n = 3,116) from the Project on Human Development in Chicago Neighborhoods, this study examines associations between neighborhood residential instability and parent-child warmth and conflict, whether family social support moderates associations between residential instability and parent-child relationships, and variation by race/ethnicity. Multilevel models reveal that residential instability undermines parent-child relationship qualities, particularly for non-White individuals. Family support is a protective factor for families in less stable neighborhoods, and specifically buffers the association between neighborhood residential instability and reduced parent-child warmth. Among Hispanics, family support mitigates the association between residential instability and heightened parent-child conflict. Findings highlight residential instability as a detriment to parent-child relationships; families in unstable neighborhoods may benefit from family social support.

PMID- 27695138 TI - Effects of Religiosity Dimensions on Physical Health across Non-elderly Black and White American Panels. AB - This investigation-based on a three-wave national panel of Black and White Americans aged 64 or younger at wave one-gauges variation across races in the indirect, moderating, and direct effects of public and subjective religiosity on a latent physical health outcome comprising chronic illnesses, subjective health, and functional limitations. The multi-population LISREL model specifically addresses the mechanisms through which religiosity is typically presumed to indirectly foster health: enhancement of social support and self-appraisals, and suppression of stress-exposure and unhealthy habits. The extent to which religiosity buffers or exacerbates the impact of specific stressors is also examined. The impact of religiosity on health appears to hinge on race and religiosity dimension: Public religiosity indirectly enhances Blacks' health slightly, and apparently buffers any negative impact of financial strain on their health. Public religiosity does not influence Whites' health; and subjective religiosity does not influence health in either race. The models control for multiple socio-demographic factors. PMID- 27695137 TI - Tension Amplification in Tethered Layers of Bottle-Brush Polymers. AB - Molecular dynamics simulations of a coarse-grained bead-spring model have been used to study the effects of molecular crowding on the accumulation of tension in the backbone of bottle-brush polymers tethered to a flat substrate. The number of bottle-brushes per unit surface area, Sigma, as well as the lengths of the bottle brush backbones Nbb (50 <= Nbb <= 200) and side chains Nsc (50 <= Nsc <= 200) were varied to determine how the dimensions and degree of crowding of bottle brushes give rise to bond tension amplification along the backbone, especially near the substrate. From these simulations, we have identified three separate regimes of tension. For low Sigma, the tension is due solely to intramolecular interactions and is dominated by the side chain repulsion that governs the lateral brush dimensions. With increasing Sigma, the interactions between bottle brush polymers induce compression of the side chains, transmitting increasing tension to the backbone. For large Sigma, intermolecular side chain repulsion increases, forcing side chain extension and reorientation in the direction normal to the surface and transmitting considerable tension to the backbone.

PMID- 27695141 TI - 'They don't live in my house every day': How understanding lives can aid understandings of smoking. AB - While the prevalence of smoking in western countries has substantially reduced following the introduction of comprehensive tobacco control programs, reduction strategies such as the introduction of smokefree legislation, media campaigns and individual and group support for people trying to quit have been less successful with people living on low income, suggesting the need for new ways to engage with people who smoke. We argue that, rather than focusing solely on researching smoking behaviors to generate new understandings of why people smoke, people working in the broad area of public health should look more widely at peoples' lives in order to understand their smoking. Using a biographical, narrative perspective as part of a wider ethnographic study of 12 families living in one community within Liverpool in 2006, we argue that understandings that position smoking purely as a harmful, deviant behavior, fail to capture the cultural complexity of the lives of smokers and the changing place and meaning of cigarettes over a person's lifetime, and may explain why smokers fail to engage with smoking cessation services and continue to smoke.

PMID- 27695142 TI - Exploiting Dual Otoacoustic Emission Sources. AB - Two distinct processes generate otoacoustic emissions (OAEs). Reflection-source emissions, here recorded as stimulus frequency OAEs, are optimally informative at low sound levels and are more sensitive to slight hearing loss; they have been linked to cochlear amplifier gain and tuning. Distortion-source emissions are strongest at moderate-high sound levels and persist despite mild hearing loss; they likely originate in the nonlinear process of hair cell transduction. In this preliminary study, we exploit the unique features of each by generating a combined reflection-distortion OAE profile in normal hearing and hearing-impaired ears. Distortion-product (DP) and stimulus-frequency (SF) OAEs were recorded over a broad range of stimulus levels and frequencies. Individual I/O and transfer functions were generated for both emission types in each ear, and OAE peak strength, compression threshold, and rate of compression were calculated. These combined SFOAE and DPOAE features in normal and hearing-impaired ears may provide a potentially informative and novel index of hearing loss. This is an initial step toward utilizing OAE source in characterizing cochlear function and dysfunction. PMID- 27695143 TI - Discriminant Analysis of Time Series in the Presence of Within-Group Spectral Variability. AB - Many studies record replicated time series epochs from different groups with the goal of using frequency domain properties to discriminate between the groups. In many applications, there exists variation in cyclical patterns from time series in the same group. Although a number of frequency domain methods for the discriminant analysis of time series have been explored, there is a dearth of models and methods that account for within-group spectral variability. This article proposes a model for groups of time series in which transfer functions are modeled as stochastic variables that can account for both between-group and within-group differences in spectra that are identified from individual replicates. An ensuing discriminant analysis of stochastic cepstra under this model is developed to obtain parsimonious measures of relative power that optimally separate groups in the presence of within-group spectral variability. The approach possess favorable properties in classifying new observations and can be consistently estimated through a simple discriminant analysis of a finite number of estimated cepstral coefficients. Benefits in accounting for within group spectral variability are empirically illustrated in a simulation study and through an analysis of gait variability. PMID- 27695144 TI - The Effect of mGluR5 Antagonism During Binge Drinkingon Subsequent Ethanol Intake in C57BL/6J Mice: Sex- and Age-Induced Differences. AB - BACKGROUND: Binge ethanol (EtOH) intake during adolescence leads to an array of behavioral and cognitive consequences including elevated intake of EtOH during adulthood, with female mice showing greater susceptibility than males. Administration of the metabotropic glutamate receptor 5 (mGluR5) antagonist 3-((2 Methyl-1,3-thiazol-4-yl)ethynyl)pyridine (MTEP) has been shown to reduce EtOH self-administration in adult male mice, but little is known about its effect on female and adolescent mice. METHODS: MTEP (0, 10, 20 mg/kg, i.p.) was repeatedly administered to female and male, adult and adolescent C57BL/6J mice during binge sessions using the scheduled high alcohol consumption paradigm. Next, we assessed whether MTEP administration during binge altered the subsequent 24-hour EtOH intake following a period of abstinence. Finally, we investigated whether MTEP administration during binge followed by an abstinence period altered mRNA of glutamatergic genes within the nucleus accumbens of female mice. RESULTS: MTEP significantly decreased binge EtOH intake in all mice, but only female mice exhibited altered subsequent 24-hour EtOH intake. Interestingly, the alteration in subsequent EtOH intake in female animals was age dependent, with adolescent exposure to MTEP during binge decreasing 24-hour intake and adult exposure to MTEP during binge increasing 24-hour intake. Finally, while there were no effects of MTEP pretreatment on the genes examined, there was a robust age effect found during analysis of mGluR1 (Grm1), mGluR5 (Grm5), the NR2A subunit of the NMDA receptor (Grin2a), phosphatidylinositol 3-kinase (Pik3r1), mammalian target of rapamycin (Mtor), and extracellular signal-regulated kinase (Mapk1) mRNA, with adolescent female animals having lower expression than their adult counterparts. CONCLUSIONS: Collectively, the present findings add to existing evidence implicating the contribution of long-term effects of adolescent binge drinking to enhance alcohol abuse in adulthood, while suggesting that mGluR5 antagonism may not be the best pharmacotherapy to treat binge alcohol consumption in female and adolescent animals. PMID- 27695146 TI - Stress-Related Symptoms and Suicidal Ideation: The Roles of Rumination and Depressive Symptoms Vary by Gender. AB - There is a growing body of literature suggesting that reactions to stressful life events, such as intrusive thoughts, physiological hyperarousal, and cognitive/behavioral avoidance (i.e., stress-related symptoms) may increase risk for thinking about and attempting suicide. Cognitive vulnerability models have identified rumination (i.e., perseverating on a negative mood) as a maladaptive response that may increase risk for suicidal behavior, as it has also been linked to depression. The present study examined the direct and indirect effects of stress-related symptoms on suicidal ideation through rumination and depressive symptoms. Participants were 1375 young adults, primarily non-White (78 %) females (72 %), recruited from a public university in the Northeastern U.S., who completed measures of stress-related symptoms (as a response to a stressful event), rumination, depressive symptoms, and suicidal ideation. The relation between stress-related symptoms and suicidal ideation was accounted for by the brooding subtype of rumination and depressive symptoms among females. Depressive symptoms, but not rumination, better accounted for suicidal ideation among males. These findings suggest that the role of brooding and depressive symptoms in the relationship between stress-related symptoms and suicidal ideation may vary by gender.

Due to dramatic levels of adult mortality reached during the late 1970s, growing up with a single parent is not. Using nationally representative, cross-sectional data, we estimate that about 12% of children under age 18 co-reside with only one of their biological parents. Using longitudinal data representative of the Mekong River Valley, we find this proportion to be declining. Nearly half of these children live in nuclear families (single parent with or without a step-parent), even though they live in multigenerational families more frequently than children who live with both their parents, especially, when young and not living with their mother. Last, we consider differences in socioeconomic conditions and child educational outcomes by number of co-residing parents. PMID- 27695145 TI - Childhood Maltreatment Exposure and Disruptions in Emotion Regulation: A Transdiagnostic Pathway to Adolescent Internalizing and Externalizing Psychopathology. AB - Child maltreatment is a robust risk factor for internalizing and externalizing psychopathology in children and adolescents. We examined the role of disruptions in emotion regulation processes as a developmental mechanism linking child maltreatment to the onset of multiple forms of psychopathology in adolescents. Specifically, we examined whether child maltreatment was associated with emotional reactivity and maladaptive cognitive and behavioral responses to distress, including rumination and impulsive behaviors, in two separate samples. We additionally investigated whether each of these components of emotion regulation were associated with internalizing and externalizing psychopathology and mediated the association between child maltreatment and psychopathology. Study 1 included a sample of 167 adolescents recruited based on exposure to physical, sexual, or emotional abuse. Study 2 included a sample of 439 adolescents in a community-based cohort study followed prospectively for 5 years. In both samples, child maltreatment was associated with higher levels of internalizing psychopathology, elevated emotional reactivity, and greater habitual engagement in rumination and impulsive responses to distress. In Study 2, emotional reactivity and maladaptive responses to distress mediated the association between child maltreatment and both internalizing and externalizing psychopathology. These findings provide converging evidence for the role of emotion regulation deficits as a transdiagnostic developmental pathway linking child maltreatment with multiple forms of psychopathology.

AB - The outcomes of a pilot-scale study of the rejection of trihalomethanes (THMs) precursors by commercial ultrafiltration/nanofiltration (UF/NF) spiral-wound membrane elements are presented based on a single surface water source in Scotland. The study revealed the expected trend of increased flux and permeability with increasing pore size for the UF membranes; the NF membranes provided similar fluxes despite the lower nominal pore size. The dissolved organic carbon (DOC) passage decreased with decreasing molecular weight cut-off, with a less than one-third the passage recorded for the NF membranes than for the UF ones. The yield (weight % total THMs per DOC) varied between 2.5% and 8% across all membranes tested, in reasonable agreement with the literature, with the aromatic polyamide membrane providing both the lowest yield and lowest DOC passage. The proportion of the hydrophobic (HPO) fraction removed was found to increase with decreasing membrane selectivity (increasing pore size), and THM generation correlated closely (R2 = 0.98) with the permeate HPO fractional concentration. PMID- 27695149 TI - Rerandomization to Balance Tiers of Covariates. AB - When conducting a randomized experiment, if an allocation yields treatment groups that differ meaningfully with respect to relevant covariates, groups should be rerandomized. The process involves specifying an explicit criterion for whether an allocation is acceptable, based on a measure of covariate balance, and rerandomizing units until an acceptable allocation is obtained. Here we illustrate how rerandomization could have improved the design of an already conducted randomized experiment on vocabulary and mathematics training programs, then provide a rerandomization procedure for covariates that vary in importance, and finally offer other extensions for rerandomization, including methods addressing computational efficiency. When covariates vary in a priori importance, better balance should be required for more important covariates. Rerandomization based on Mahalanobis distance preserves the joint distribution of covariates, but balances all covariates equally. Here we propose rerandomizing based on Mahalanobis distance within tiers of covariate importance. Because balancing covariates in one tier will in general also partially balance covariates in other tiers, for each subsequent tier we explicitly balance only the components orthogonal to covariates in more important tiers.

AB - Students identified with learning disabilities experience markedly lower levels of science and mathematics achievement than students who are not identified with a learning disability. Seemingly compounding their disadvantage, students with learning disabilities also complete more credits in non-core coursework traditionally considered non-academic coursework-than students who are not identified with a learning disability. The Education Longitudinal Study of 2002, a large national dataset with both regular and special education high school students, is utilized to determine whether credit accumulation in certain types of non-core coursework, such as Technology and Communications courses, is associated with improved science and math course-taking outcomes for students with learning disabilities. Results show that credit accumulation in Technology and Communications coursework uniquely benefits the science course-taking, and comparably benefits the math course-taking, of students identified with learning disabilities in contrast to students who are not identified with a learning disability. PMID- 27695151 TI - Effect of rate of pyrolysis on the textural properties of naturally-templated porous carbons from alginic acid. AB - The effect of pyrolysis rate on the properties of alginic acid-derived carbonaceous materials, termed Starbon(r), was investigated. Thermal Gravimetry IR was used to prepare porous carbons up to 800 degrees C at several rates and highlighted increased CO2 production at higher pyrolysis rates. N2 porosimetry of the resultant carbons shows how pyrolysis rate affects both the mesopore structure and thus surface area and surface energy. Surface capacity of these carbons was analysed by methylene blue dye adsorption. In general, as the rate of pyrolysis increased, the mesopore content and adsorbent capacity decreased. It is considered here that the rapid production of volatiles at these higher rates causes structural collapse of the non-templated pore network. The work here demonstrates that pyrolysis rate is a key variable which needs to be controlled to maximise the textural properties of Starbon(r) required for adsorption applications. PMID- 27695153 TI - Reconsidering the "acculturation gap" narrative through an analysis of parent adolescent acculturation differences in Mexican American families. AB - Using a sample of 193 Mexican American adolescents (M age at Wave 1 = 14) and three waves of data over two years, this study longitudinally examined the effects of parent-youth acculturation differences, relative to no differences, on parent-adolescent relationship quality and youth problem behavior. We examined parent-youth differences in overall acculturation, Mexican acculturation, and American acculturation. We differentiated between cases in which the adolescent was more acculturated than the parent and cases in which the parent was more acculturated than the adolescent. Adolescents were more commonly similar to their parents than different. Where differences existed, adolescents were not uniformly more American than their parents, no type of difference was associated with parent-adolescent relationship quality, and no type of difference in overall acculturation was associated with youth problem behavior. One type of difference by dimension (adolescent had less Mexican acculturation than mother) was associated with less risk of problem behavior. PMID- 27695152 TI - Solid-phase microextraction technology for in vitro and in vivo metabolite analysis. AB - Analysis of endogenous metabolites in biological samples may lead to the identification of biomarkers in metabolomics studies. To achieve accurate sample analysis, a combined method of continuous quick sampling and extraction is required for online compound detection. Solid-phase microextraction (SPME) integrates sampling, extraction and concentration into a single solvent-free step for chemical analysis. SPME has a number of advantages, including simplicity, high sensitivity and a relatively non-invasive nature. In this article, we reviewed SPME technology in in vitro and in vivo analyses of metabolites after the ingestion of herbal medicines, foods and pharmaceutical agents. The metabolites of microorganisms in dietary supplements and in the gastrointestinal tract will also be examined. As a promising technology in biomedical and pharmaceutical research, SPME and its future applications will depend on advances in analytical technologies and material science. PMID- 27695154 TI - Forecasting natural hazards, performance of scientists, ethics, and the need for transparency. AB - Landslides are one of several natural hazards. As other natural hazards, landslides are difficult to predict, and their forecasts are uncertain. The uncertainty depends on the poor understanding of the phenomena that control the slope failures, and on the inherent complexity and chaotic nature of the landslides. This is similar to other natural hazards, including hurricanes, earthquakes, volcanic eruptions, floods, and droughts. Due to the severe impact of landslides on the population, the environment, and the economy, forecasting landslides is of scientific interest and of societal relevance, and scientists attempting to forecast landslides face known and new problems intrinsic to the multifaceted interactions between science, decision-making, and the society. The problems include deciding on the authority and reliability of individual scientists and groups of scientists, and evaluating the performances of individual scientists, research teams, and their institutions. Related problems lay in the increasing subordination of research scientists to politics and decision-makers, and in the conceptual and operational models currently used to organize and pay for research, based on apparently objective criteria and metrics, considering science as any other human endeavor, and favoring science that produces results of direct and immediate application. The paper argues that the consequences of these problems have not been considered fully. PMID- 27695155 TI - Multi-Output Decision Trees for Lesion Segmentation in Multiple Sclerosis. AB - Multiple Sclerosis (MS) is a disease of the central nervous system in which the protective myelin sheath of the neurons is damaged. MS leads to the formation of lesions, predominantly in the white matter of the brain and the spinal cord. The number and volume of lesions visible in magnetic resonance (MR) imaging (MRI) are important criteria for diagnosing and tracking the progression of MS. Locating and delineating lesions manually requires the tedious and expensive efforts of highly trained raters. In this paper, we propose an automated algorithm to segment lesions in MR images using multi-output decision trees. We evaluated our algorithm on the publicly available MICCAI 2008 MS Lesion Segmentation Challenge training dataset of 20 subjects, and showed improved results in comparison to state-of-the-art methods. We also evaluated our algorithm on an in-house dataset of 49 subjects with a true positive rate of 0.41 and a positive predictive value 0.36. PMID- 27695156 TI - Evaluation of a projection-domain lung nodule insertion technique in thoracic CT. AB - Task-based assessment of computed tomography (CT) image quality requires a large number of cases with ground truth. Inserting lesions into existing cases to simulate positive cases is a promising alternative approach. The aim of this study was to evaluate a recently-developed raw-data based lesion insertion technique in thoracic CT. Lung lesions were segmented from patient CT images, forward projected, and reinserted into the same patient CT projection data. In total, 32 nodules of various attenuations were segmented from 21 CT cases. Two experienced radiologists and 2 residents blinded to the process independently evaluated these inserted nodules in two sub-studies. First, the 32 inserted and the 32 original nodules were presented in a randomized order and each received a rating score from 1 to 10 (1=absolutely artificial to 10=absolutely realistic). Second, the inserted and the corresponding original lesions were presented side by-side to each reader, who identified the inserted lesion and provided a confidence score (1=no confidence to 5=completely certain). For the randomized evaluation, discrimination of real versus artificial nodules was poor with areas under the receiver operative characteristic curves being 0.69 (95% CI: 0.58 0.78), 0.57 (95% CI: 0.46-0.68), and 0.62 (95% CI: 0.54-0.69) for the 2 radiologists, 2 residents, and all 4 readers, respectively. For the side-by-side evaluation, although all 4 readers correctly identified inserted lesions in 103/128 pairs, the confidence score was moderate (2.6). Our projection-domain based lung nodule insertion technique provides a robust method to artificially generate clinical cases that prove to be difficult to differentiate from real cases. PMID- 27695157 TI - The effects of compressive sensing on extracted features from tri-axial swallowing accelerometry signals. AB - Acquiring swallowing accelerometry signals using a comprehensive sensing scheme may be a desirable approach for monitoring swallowing safety for longer periods of time. However, it needs to be insured that signal characteristics can be recovered accurately from compressed samples. In this paper, we considered this issue by examining the effects of the number of acquired compressed samples on the calculated swallowing accelerometry signal features. We used tri-axial swallowing accelerometry signals acquired from seventeen stroke patients (106 swallows in total). From acquired signals, we extracted typically considered signal features from time, frequency and time-frequency domains. Next, we compared these features from the original signals (sampled using traditional sampling schemes) and compressively sampled signals. Our results have shown we can obtain accurate estimates of signal features even by using only a third of original samples. PMID- 27695158 TI - Reduction of Cortisol Levels and Participants' Responses Following Art Making. AB - This quasi-experimental study investigated the impact of visual art making on the cortisol levels of 39 healthy adults. Participants provided saliva samples to assess cortisol levels before and after 45 minutes of art making. Participants also provided written responses about the experience at the end of the session. Results indicate that art making resulted in statistically significant lowering of cortisol levels. Participants' written responses indicated that they found the art-making session to be relaxing, enjoyable, helpful for learning about new aspects of self, freeing from constraints, an evolving process of initial struggle to later resolution, and about flow/losing themselves in the work. They also reflected that the session evoked a desire to make art in the future. There were weak associations between changes in cortisol level and age, time of day, and participant responses related to learning about one's self and references to an evolving process in art making. There were no significant differences in outcomes based on prior experiences with art making, media choice, or gender. PMID- 27695159 TI - Characterization of Obesity in the Prader-Labhart-Willi Syndrome: Fatness Patterning. AB - A multidisciplinary study involving cytogenetic, clinical, and anthropometric assessments of Prader-Labhart-Willi Syndrome (PLWS) has focused on improving diagnosis and prognosis in this complex condition. Since one of the major features of PLWS is obesity, 7 of the 26 measurements in the anthropometric evaluation were skinfold thicknesses at different body sites. Forty individuals with PLWS have been assessed. Z-scores were computed for skinfold measurements to examine quantitative differences for fatness at different sites. Data on PLWS individuals, grouped by age, sex, and chromosome type, were compared with normative data for skinfolds. The results suggest that males with PLWS have three times the fatness scores of other males their age, while scores for PLWS females average only twice those of normals. Our research illustrates the utility of anthropometry in the evaluation of patients in clinical genetics and offers a comprehensive approach to the heterogeneity observed in PLWS.

PMID- 27695160 TI - Declines in Crime and Teen Childbearing: Identifying Potential Explanations for Contemporaneous Trends. AB - OBJECTIVES: The previous 25 years have witnessed remarkable upheavals in the social landscape of the United States. Two of the most notable trends have been dramatic declines in levels of crime as well as teen childbearing. Much remains unknown about the underlying conditions that might be driving these changes. More importantly, we do not know if the same distal factors that are responsible for the drop in the crime rate are similarly implicated in falling rates of teen births. We examine four overarching potential explanations: fluctuations in economic opportunity, shifting population demographics, differences in state level policies, and changes in expectations regarding health and mortality. METHODS: We combine state-specific data from existing secondary sources and model trajectories of violent crime, homicides, robberies, and teen fertility over a 20 year period from 1990 to 2010 using simultaneous fixed-effects regression models. RESULTS: We find that 4 of the 21 predictors examined - growth in the service sector of the labor market, increasing racial diversity especially among Hispanics, escalating levels of migration, and the expansion of family planning services to low-income women - offer the most convincing explanations for why rates of violent crime and teen births have been steadily decreasing over time. Moreover, we are able to account for almost a quarter of the joint declines in violent crime and teen births. CONCLUSIONS: Our conclusions underscore the far reaching effects that aggregate level demographic conditions and policies are likely to have on important social trends that might, at first glance, seem unrelated. Furthermore, the effects of policy efforts designed to target outcomes in one area are likely to spill over into other domains. PMID- 27695162 TI - NORMATIVE STANDARDS AND COMPARISON OF ANTHROPOMETRIC DATA OF WHITE AND BLACK NEWBORN INFANTS. AB - We report normative standards for length, weight, 17 craniofacial dimensions, 5 hand and foot measurements, 7 circumferences, 9 skinfold thicknesses, penile length, and testicular volume in black and white newborns. No significant differences in these variables were found between black males and females. White males had greatest craniofacial height, head length, head breadth, minimum frontal diameter, bizygomatic diameter, and head circumference, whereas white females had largest medial calf, thigh, forearm, and subscapular skinfolds. White infants had largest weight, head circumference, head length, head breadth, calf and chest circumferences, and medial calf and forearm skinfolds, whereas nose breadth, mouth breadth, and penile length were greatest in black newborns. PMID- 27695163 TI - Development and testing of Baylor Scott & White Health's "Attitudes and Practices of Patient Safety Survey". AB - Improving the quality of patient care requires a culture attuned to safety. We describe the development, implementation, and psychometric evaluation of the Attitudes and Practices of Patient Safety Survey (APPSS) within the Baylor Scott & White Health system. The APPSS was designed to enable safety culture data to be collected and aggregated at the unit level to identify high-priority needs. The survey, with 27 Likert-scale core questions divided into 4 concept domains and 2 open-ended questions, was administered electronically to employees with direct patient care responsibilities (n = 16,950). The 2015 response rate was 50.4%. The Cronbach's alpha values for the four domains ranged from 0.78 to 0.90, indicating strong internal consistency. Confirmatory factor analysis results were mixed but were comparable to those of established safety culture surveys. Over the years, the adaptability of the APPSS has proven helpful to administrative and clinical leaders alike, and the survey responses have led to the creation of programs to improve the organization's patient safety culture. In conclusion, the APPSS provides a reliable measure of patient safety culture and may be useful to other health care organizations seeking to improve the quality and safety of the care they provide. PMID- 27695164 TI - Safety and efficacy of 2-octyl-cyanoacrylate in the management of patients with gastric and duodenal varices who are not candidates for transjugular intrahepatic portosystemic shunts. AB - Gastric variceal bleeding is associated with significant morbidity and mortality in patients with portal hypertension and cirrhosis. Options are limited for patients who are not candidates for transjugular intrahepatic portosystemic shunts (TIPS). Cyanoacrylate injections have been reported to be efficacious in previous case series. The aim of this retrospective study was to report our single-center experience with the safety and efficacy of 2-octyl-cyanoacrylate in patients who were not TIPS candidates. Electronic medical records were reviewed for 16 patients who underwent a total of 18 esophagogastroduodenoscopies for acute gastric or duodenal variceal bleeding and secondary prophylaxis of gastric varices; 14 patients had cirrhosis with an average Model for End-Stage Liver Disease score of 16, and 2 patients had noncirrhotic portal hypertension. Primary endpoints of the study included early and delayed rebleeding rate, complications, and death or liver transplantation. The rebleeding rate (early or delayed) was 7%, and no complications were found. One death was reported (unrelated to the procedure). In conclusion, 2-octyl-cyanoacrylate is a safe and effective alternative for non-TIPS candidates who present with acute gastric variceal bleeding given its low rebleeding and complication rate. PMID- 27695165 TI - Usefulness of ultrasonographic measurement of the diameter of the inferior vena cava to predict responsiveness to intravascular fluid administration in patients with cancer. AB - We conducted an observational, longitudinal prospective study in which we measured the diameters of the inferior vena cava (IVC) of 47 patients using ultrasonography. The aim of our study was to assess the state of blood volume and to determine the percentage of patients who responded to intravascular volume expansion. Only 17 patients (36%) responded to fluid management. A higher number of responding patients had cardiovascular failure compared with nonresponders (82% vs. 50%, P = 0.03). Among the patients with cardiovascular failure, the probability of finding responders was 4.6 times higher than that of not finding responders (odds ratio, 4.66; 95% confidence interval, 1.10-19.6; P = 0.04). No significant difference was observed in the mortality rate between the two groups (11% vs. 23%, P = 0.46). In conclusion, responding to intravascular volume expansion had no impact on patient survival in the intensive care unit.

AB - Early cholecystectomy for patients with acute cholecystitis may not be possible in some clinical settings. Percutaneous gallbladder aspiration (PGBA) offers an alternative approach, but the benefits and risks of this procedure are unclear. We synthesized data on the outcomes of PGBA in acute cholecystitis patients using data sources from online databases, including MEDLINE and EMBASE, and bibliographies of included studies from January 2000 through December 2015. Two reviewers independently reviewed and critiqued the quality of each study. Seven eligible studies met our criteria. The success rates in single PGBA and repetitive PGBA (2-4 times) were 50% to 93% and 76% to 96%, respectively. Complication rates were 0% to 8% and were unrelated to the size of needle gauge used for aspiration and the number of aspirations. Salvage percutaneous cholecystostomy (PC) and urgent surgery were required in 0% to 43% of patients and 0% to 4% of patients, respectively. Two studies with antibiotic instillation had clinical success rates of 95% and 96%. In conclusion, repetitive PGBA combined with antibiotic instillation and salvage PC are useful alternatives to early cholecystectomy in patients with acute cholecystitis. PMID- 27695168 TI - Epidural analgesia complicated by dural ectasia in the Marfan syndrome. AB - Patients with the Marfan syndrome are considered to be high risk during pregnancy and warrant a complete multidisciplinary evaluation. One goal is to minimize hemodynamic fluctuations during labor since hypertensive episodes may result in aortic dissection or rupture. Although they may prevent these complications, neuraxial techniques may be complicated by dural ectasia. The case of a parturient with the Marfan syndrome and mild dural ectasia is presented. During attempted labor epidural placement, unintentional dural puncture occurred. A spinal catheter was used for adequate labor analgesia, and a resultant postdural puncture headache was alleviated by an epidural blood patch under fluoroscopic guidance. PMID- 27695169 TI - Bilateral congenital pseudoarthrosis of the clavicles in a newborn. AB - Bilateral congenital pseudoarthrosis of the clavicles is extremely rare.

PMID- 27695170 TI - Wedgie-associated radiculitis in a quinquagenarian. AB - Wedgies-the upward yanking of another's underpants from the rear to wedge them between the buttocks-can be administered playfully, maliciously, or adventurously; at forces ranging from gentle to "atomic"; and with or without the foreknowledge or consent of the recipient. Wedgies have been documented anecdotally in the popular Internet literature, with chief emphasis on their sensation-seeking or momentary entertainment value to the giver and recipient. Most participants are typically young; however, we report the case of a 50-year old man who sustained chronic, painless radiculitis after he received an unanticipated wedgie of moderate force. This report-apparently the first of its kind in the medical literature-serves as notice that exchanging wedgies is not merely a juvenile act or immature prank: the outcome can be injurious. PMID- 27695171 TI - Synchronous trifocal colorectal cancer. AB - Synchronous colorectal cancers (SCRCs) have been increasingly diagnosed due to emerging diagnostic modalities. The presence of three or more synchronous colorectal cancers has, however, only rarely been reported. A 76-year-old white man presented for management of two concurrent colorectal adenocarcinomas in the left colon evidenced on total colonoscopy. Preoperative abdominal ultrasonography and thoracoabdominal computed tomography were negative for metastatic disease. The patient underwent an elective left hemicolectomy. The pathology report ultimately showed the presence of three moderately differentiated, distinct colorectal cancers. The patient experienced an uneventful recovery. PMID- 27695172 TI - Extreme anemia (hemoglobin 1.8 g/dL) secondary to colon cancer. AB - We present the case of a 34-year-old man who presented to the emergency department with complaints of generalized fatigue and palpitations, with a heart rate of approximately 100 beats per minute and an orthostatic blood pressure of 80/30 mm Hg upon standing. A hemoglobin of 1.8 g/dL was discovered. A positive fecal occult blood test led to the diagnosis of colon cancer. Once the cancer was resected, the patient's anemia resolved. PMID- 27695173 TI - Acute myeloid leukemia presenting as galactorrhea. AB - Acute myeloid leukemia (AML) presents with symptoms related to pancytopenia (weakness, infections, bleeding diathesis) and organ infiltration with leukemic cells. Galactorrhea is an uncommon manifestation of AML. We report a case of AML presenting with galactorrhea. PMID- 27695174 TI - Acute promyelocytic leukemia after renal transplant and filgrastim treatment for neutropenia. AB - Prolonged immunosuppression in solid organ transplant recipients has been considered a risk for developing opportunistic infections and malignancies. Acute leukemia is a rare complication. We report a case of acute promyelocytic leukemia (APL) (FAB M3) after cadaveric renal transplant for focal segmental glomerulosclerosis in a 24-year-old woman. Her immunosuppressive therapy included tacrolimus, mycophenolate mofetil, and prednisone. Approximately 2 years after transplant, she became pancytopenic, prompting administration of filgrastim. A few doses caused a markedly increased blast count, resulting in a diagnosis of APL. She was successfully treated with all-trans-retinoic acid and arsenic trioxide. Myeloproliferative neoplasms after organ transplant or due to filgrastim are rare. PMID- 27695175 TI - Vanishing lung syndrome. AB - Giant bullae often mimic pneumothorax on radiographic appearance. We present the case of a 55-year-old man admitted to a referring hospital with dyspnea, cough, and increasing sputum production; he refused thoracotomy for tension pneumothorax and presented to our hospital for a second opinion. A computed tomography (CT) scan at our hospital revealed a giant bulla, which was managed conservatively as an exacerbation of chronic obstructive pulmonary disease. Thoracic surgery was consulted but advised against bullectomy. Giant bullae can easily be misdiagnosed as a pneumothorax, but the management of the two conditions is vastly different. Distinguishing between the two may require CT scan. Symptomatic giant bullae are managed surgically. We highlight the etiology, presentation, diagnosis, and treatment of bullous lung disease, especially in comparison to pneumothorax. PMID- 27695176 TI - Partial annular pancreas. AB - Annular pancreas is a developmental anomaly that can be associated with other conditions such as Down syndrome, duodenal atresia, and Hirschsprung disease. A band of pancreatic tissue, in continuity with the pancreatic head, completely or incompletely encircles the descending duodenum, sometimes assuming a "crocodile jaw" configuration. We present the case of an adult who presented with epigastric pain and vomiting and was found to have annular pancreas. PMID- 27695177 TI - Abdominal apoplexy resulting in small bowel obstruction. AB - Abdominal apoplexy is a rare hemorrhagic condition involving the small arteries or veins within the abdominal cavity. A high degree of clinical suspicion, followed by appropriate diagnostic workup and therapeutic intervention, is critical, as nonoperative mortality approaches 100%. Contrary to most previously reported cases, which were associated with hemoperitoneum, we present a patient in which gastroduodenal artery dissection resulted in an organized retroperitoneal hematoma with local compression of the duodenum and subsequent bowel obstruction, resulting in vomiting, aspiration, and death. PMID- 27695178 TI - Fulminant ulcerative colitis complicated by treatment-refractory bacteremia. AB - Severe ulcerative colitis is defined by more than six bloody stools daily and evidence of toxicity, demonstrated by fever, tachycardia, anemia, or an elevated erythrocyte sedimentation rate. Fulminant disease represents a subset of severe disease with signs and symptoms suggestive of increased toxicity. Treatment of severe colitis includes intravenous corticosteroid administration, with consideration of intravenous infliximab 5 mg/kg. Failure to show improvement after 3 to 5 days is an indication for colectomy or treatment with intravenous cyclosporine. We report a 23-year-old Hispanic woman with decompensated cirrhosis presenting with new-onset fulminant ulcerative colitis and resulting polymicrobial bacteremia, requiring colectomy for infection source control and colitis treatment. PMID- 27695179 TI - Isolated naratriptan-associated ischemic colitis. AB - We report a 41-year-old woman who developed histology- and colonoscopy-proven ischemic colitis with the use of naratriptan not exceeding the maximum 2 doses a day and 3 days per week and without a known medical or cardiovascular history. By exclusion of other causes of colonic ischemia, naratriptan was considered the sole causal agent. Discontinuation of naratriptan resulted in a complete clinical recovery. To date, our patient is the youngest known patient to develop ischemic colitis on isolated naratriptan in the setting of no known medical risk factors or predisposing medical condition. Even though triptans are commonly used for the abortive treatment of migraine headaches, such a reported side effect is rare; however, careful assessment and individual patient-based treatment is advised. PMID- 27695180 TI - Acute renal failure due to vancomycin toxicity in the setting of unmonitored vancomycin infusion. AB - Vancomycin-induced nephrotoxicity is a commonly feared and largely preventable adverse effect of vancomycin therapy. We present the case of a 56-year-old woman who developed acute renal failure requiring hemodialysis as a result of unmonitored vancomycin infusions for the treatment of osteomyelitis. PMID- 27695181 TI - Hemopericardium with tamponade following rivaroxaban administration and its attenuation by CYP3A4 inhibitors. AB - Novel oral anticoagulants including the factor Xa inhibitor rivaroxaban are important alternatives to warfarin for the prevention of thromboembolic stroke in patients with nonvalvular atrial fibrillation. The pharmacology and metabolism of these agents differ from those of the vitamin K antagonists used over the decades preceding their introduction. We present a case of spontaneous hemopericardium and cardiac tamponade following administration of rivaroxaban. A review of the patient's medications revealed a total of seven agents known to be metabolized through cytochrome P450 3A4 (CYP3A4), the major pathway for rivaroxaban metabolism. While most physicians are familiar with recommendations to monitor renal function in patients prescribed rivaroxaban, we suspect that many fail to evaluate possible interactions with other agents having CYP3A4 inhibitory or inducer activity. PMID- 27695182 TI - Management of a renal fungal bezoar caused by multidrug-resistant Candida glabrata. AB - We describe our management of an immunocompetent individual who developed obstructive uropathy and candidemia as a result of a fungal bezoar in the kidney. These sequelae arose from candiduria, provoked after several courses of antibiotics. Successful treatment included therapy with both culture-appropriate intravenous antifungals and operative intervention, including direct irrigation of the affected kidney with amphotericin B, relief of renal obstruction with a ureteral stent, a percutaneous nephrostomy tube, and ultimately endoscopic removal of the fungal bezoar. Our patient was successfully treated as evidenced by negative urine culture and lack of ongoing symptomatology. PMID- 27695183 TI - Lymphogranuloma venereum proctitis. AB - We describe a 60-year-old man who presented with rectal pain and bleeding of a month's duration. His presentation was highly suggestive of lymphogranuloma venereum (LGV) proctitis. Nucleic acid amplification for chlamydia and gonorrhea via rectal swab revealed evidence supportive of anorectal chlamydia. Treatment with doxycycline resulted in complete resolution of his symptoms. PMID- 27695184 TI - Placement of the AbbVie PEG-J tube for the treatment of Parkinson's disease in the interventional radiology suite. AB - The primary treatment for Parkinson's disease is dopaminergic stimulation. Although levodopa has historically been administered orally, maintaining a predictable plasma concentration of the drug is challenging. As a result, enteral administration of carbidopa/levodopa (Duopa) has emerged as a promising tool in the treatment of the disease. This requires placement of an enteric catheter, two of which have been approved by the Food and Drug Administration for delivery of Duopa. The approved tubes are placed using the "peroral" or "pull" technique, a method traditionally requiring endoscopy. This technical note describes placement of the AbbVie PEG-J tube by means of the peroral route while utilizing only sonographic and fluoroscopic guidance. After placing an orogastric tube and achieving percutaneous access to the stomach under fluoroscopic visualization, a snare catheter is advanced through the percutaneous access into the stomach. The orogastric tube is engaged with the snare and retracted, bringing the attached snare with it to the mouth. The AbbVie PEG tube is attached to the snare, pulled back down the esophagus and into the stomach before being retracted through the percutaneous access to the skin. Finally, the AbbVie J tube is advanced through the gastrostomy tube into the proximal jejunum and attached with the provided connectors. As demonstrated, the AbbVie PEG-J tube can be placed safely and effectively using a percutaneous image-guided technique without the use of an endoscope.

No functional consequences resulted. Study of previous publications disclosed the frequency of this anomaly in adults to be approximately 3.5%. Dissection has been reported to be more frequent in the left vertebral artery when it arises directly from the aorta than when it arises from the left subclavian artery.

We present a case of giant left atrial myxoma that presented as a flulike illness. PMID- 27695188 TI - Melanoma to the heart. AB - Malignant melanoma is the third most common skin cancer yet has the highest mortality rate due to its predilection for metastasis. While the diagnosis of antemortem melanoma with cardiac metastasis is relatively uncommon, diagnosing malignant melanoma itself by first identifying a cardiac metastasis is even more rare. This vignette describes an antemortem diagnosis of melanoma in a 50-year old woman through identification of metastasis to multiple sites, including the tricuspid valve.

AB - Acute chest pain is one of the most common reasons for presentation to the emergency department. Although most etiologies of chest pain are easy to clinically ascertain with routine history, physical, and laboratory examinations, we present an important benign cause of acute chest pain that may mimic acute coronary syndrome.

AB - 7 T arterial spin labeling (ASL) faces major challenges including the increased specific absorption rate (SAR) and increased B0 and B1 inhomogeneity. This work describes the design and implementation of a dual-coil system that allows for continuous ASL (CASL) at 7 T. This system consisted of an actively detunable eight-channel transceiver head coil, and a three-channel transceiver labeling coil. Four experiments were performed in 5 healthy subjects: (i) to demonstrate that active detuning during ASL labeling reduces magnetization transfer; (ii) to measure the B1 profile at the labeling plane; (iii) to quantify B0 off-resonance at the labeling plane; and (iv) to collect in vivo CASL data. The magnetization transfer ratio in the head coil was reduced to 0.0 +/- 0.2% by active detuning during labeling. The measured B1 profiles in all 5 subjects were sufficient to satisfy the flow-driven adiabatic inversion necessary for CASL, however the actual labeling efficiency was significantly impacted by B0 off-resonance at the labeling plane. The measured CASL percent signal change in gray matter (0.94% +/- 0.10%) corresponds with the low labeling efficiency predicted by the B0 off resonance. This work demonstrates progress in the technical implementation of 7 T CASL, and reinforces the need for improved B0 homogeneity at the labeling plane. PMID- 27695194 TI - Emergence of PPR and its threat to Europe. AB - PPR is an important infectious viral disease of domestic and wild small ruminants, that threatens the food security and sustainable livelihood of farmers across Africa, the Middle East and Asia. Europe is free of the disease except in Thrace (European part of Turkey) and Israel where outbreaks occur. Following the successful eradication of RPV, PPR has been targeted by the OIE and FAO as the next viral pathogen to be eradicated by 2030. However, the recent outbreaks in Northen Africa and Thrace (European part of Turkey) represent a significant threat to mainland Europe, as a source of disease spread. We have discussed here the emergence of PPR worldwide since its discovery with particular reference to the recent outbreaks in Northen Africa and Thrace, and the potential for spread of the disease into Europe. PMID- 27695193 TI - How age of acquisition influences brain architecture in bilinguals. AB - In the present study, we explored how Age of Acquisition (AoA) of L2 affected brain structures in bilingual individuals. Thirty-six native English speakers who were bilingual were scanned with high resolution MRI. After MRI signal intensity inhomogeneity correction, we applied both voxel-based morphometry (VBM) and surface-based morphometry (SBM) approaches to the data. VBM analysis was performed using FSL's standard VBM processing pipeline. For the SBM analysis, we utilized a semi-automated sulci delineation procedure, registered the brains to an atlas, and extracted measures of twenty four pre-selected regions of interest. We addressed three questions: (1) Which areas are more susceptible to differences in AoA? (2) How do AoA, proficiency and current level of exposure work together in predicting structural differences in the brain? And (3) What is the direction of the effect of AoA on regional volumetric and surface measures? Both VBM and SBM results suggested that earlier second language exposure was associated with larger volumes in the right parietal cortex. Consistently, SBM showed that the cortical area of the right superior parietal lobule increased as AoA decreased. In contrast, in the right pars orbitalis of the inferior frontal gyrus, AoA, proficiency, and current level of exposure are equally important in accounting for the structural differences. We interpret our results in terms of current theory and research on the effects of L2 learning on brain structures and functions. PMID- 27695196 TI - Racial and Ethnic Infant Mortality Gaps and the Role of Socio-Economic Status. AB - We assess the extent to which differences in socio-economic status are associated with racial and ethnic gaps in a fundamental measure of population health: the rate at which infants die. Using micro-level Vital Statistics data from 2000 to 2004, we examine mortality gaps of infants born to white, black, Mexican, Puerto Rican, Asian, and Native American mothers. We find that between-group mortality gaps are strongly and consistently (except for Mexican infants) associated with maternal marital status, education, and age, and that these same characteristics are powerful predictors of income and poverty for new mothers in U.S. Census data. Despite these similarities, we document a fundamental difference in the mortality gap for the three high mortality groups: whereas the black-white and Puerto Rican-white mortality gaps mainly occur at low birth weights, the Native American-white gap occurs almost exclusively at higher birth weights. We further examine the one group whose IMR is anomalous compared to the other groups: infants of Mexican mothers die at relatively low rates given their socio-economic disadvantage. We find that this anomaly is driven by lower infant mortality among foreign-born mothers, a pattern found within many racial/ethnic groups. Overall, we conclude that the infant mortality gaps for our six racial/ethnic groups exhibit many commonalities, and these commonalities suggest a prominent role for socio-economic differences.

AB - Accurate and timely rice paddy field maps with a fine spatial resolution would greatly improve our understanding of the effects of paddy rice agriculture on greenhouse gases emissions, food and water security, and human health. Rice paddy field maps were developed using optical images with high temporal resolution and coarse spatial resolution (e.g., Moderate Resolution Imaging Spectroradiometer (MODIS)) or low temporal resolution and high spatial resolution (e.g., Landsat TM/ETM+). In the past, the accuracy and efficiency for rice paddy field mapping at fine spatial resolutions were limited by the poor data availability and image based algorithms. In this paper, time series MODIS and Landsat ETM+/OLI images, and the pixel- and phenology-based algorithm are used to map paddy rice planting area. The unique physical features of rice paddy fields during the flooding/open canopy period are captured with the dynamics of vegetation indices, which are then used to identify rice paddy fields. The algorithm is tested in the Sanjiang Plain (path/row 114/27) in China in 2013. The overall accuracy of the resulted map of paddy rice planting area generated by both Landsat ETM+ and OLI is 97.3%, when evaluated with areas of interest (AOIs) derived from geo-referenced field photos. The paddy rice planting area map also agrees reasonably well with the official statistics at the level of state farms (R2 = 0.94). These results demonstrate that the combination of fine spatial resolution images and the phenology-based algorithm can provide a simple, robust, and automated approach to map the distribution of paddy rice agriculture in a year.

AB - The current study aimed to estimate the cost associated with special education among children (5 to 14 years) with Fetal Alcohol Spectrum Disorder (FASD) in elementary and middle school by sex, age group, and province and territory in Canada. It was estimated that there were 6,520 students with FASD receiving special education in Canada in 2011-2012. The cost of special education among these students was 53.5 million Canadian dollars. Implications for decision- and policymakers, educational systems and school staff are discussed. PMID- 27695199 TI - Magnetically tuned, robust and efficient filtering system for spatially multimode quantum memory in warm atomic vapors. AB - Warm atomic vapor quantum memories are simple and robust, yet suffer from a number of parasitic processes which produce excess noise. For operating in a single-photon regime precise filtering of the output light is essential. Here, we report a combination of magnetically tuned absorption and Faraday filters, both light-direction insensitive, which stop the driving lasers and attenuate spurious fluorescence and four-wave mixing while transmitting narrowband Stokes and anti Stokes photons generated in write-in and readout processes. We characterize both filters with respect to adjustable working parameters. We demonstrate a significant increase in the signal-to-noise ratio upon applying the filters seen qualitatively in measurements of correlation between the Raman scattered photons. PMID- 27695200 TI - Quantum memory receiver for superadditive communication using binary coherent states. AB - We propose a simple architecture based on multimode quantum memories for collective readout of classical information keyed using a pair coherent states, exemplified by the well-known binary phase shift keying format. Such a configuration enables demonstration of the superadditivity effect in classical communication over quantum channels, where the transmission rate becomes enhanced through joint detection applied to multiple channel uses. The proposed scheme relies on the recently introduced idea to prepare Hadamard sequences of input symbols that are mapped by a linear optical transformation onto the pulse position modulation format [Guha, S. Phys. Rev. Lett.2011, 106, 240502]. We analyze two versions of readout based on direct detection and an optional Dolinar receiver which implements the minimum-error measurement for individual detection of a binary coherent state alphabet. PMID- 27695201 TI - Internal short circuit and accelerated rate calorimetry tests of lithium-ion cells: Considerations for methane-air intrinsic safety and explosion proof/flameproof protection methods. AB - Researchers with the National Institute for Occupational Safety and Health (NIOSH) studied the potential for lithium-ion cell thermal runaway from an internal short circuit in equipment for use in underground coal mines. In this third phase of the study, researchers compared plastic wedge crush-induced internal short circuit tests of selected lithium-ion cells within methane (CH4) air mixtures with accelerated rate calorimetry tests of similar cells. Plastic wedge crush test results with metal oxide lithium-ion cells extracted from intrinsically safe evaluated equipment were mixed, with one cell model igniting the chamber atmosphere while another cell model did not. The two cells models exhibited different internal short circuit behaviors. A lithium iron phosphate (LiFePO4) cell model was tolerant to crush-induced internal short circuits within CH4-air, tested under manufacturer recommended charging conditions. Accelerating rate calorimetry tests with similar cells within a nitrogen purged 353-mL chamber produced ignitions that exceeded explosion proof and flameproof enclosure minimum internal pressure design criteria. Ignition pressures within a 20-L chamber with 6.5% CH4-air were relatively low, with much larger head space volume and less adiabatic test conditions. The literature indicates that sizeable lithium thionyl chloride (LiSOCl2) primary (non rechargeable) cell ignitions can be especially violent and toxic. Because ignition of an explosive atmosphere is expected within explosion proof or flameproof enclosures, there is a need to consider the potential for an internal explosive atmosphere ignition in combination with a lithium or lithium-ion battery thermal runaway process, and the resulting effects on the enclosure. PMID- 27695198 TI - Quantum memories: emerging applications and recent advances. AB - Quantum light-matter interfaces are at the heart of photonic quantum technologies. Quantum memories for photons, where non-classical states of photons are mapped onto stationary matter states and preserved for subsequent retrieval, are technical realizations enabled by exquisite control over interactions between light and matter. The ability of quantum memories to synchronize probabilistic events makes them a key component in quantum repeaters and quantum computation based on linear optics. This critical feature has motivated many groups to dedicate theoretical and experimental research to develop quantum memory devices. In recent years, exciting new applications, and more advanced developments of quantum memories, have proliferated. In this review, we outline some of the emerging applications of quantum memories in optical signal processing, quantum computation and non-linear optics. We review recent experimental and theoretical developments, and their impacts on more advanced photonic quantum technologies based on quantum memories.

AB - In vitro meat (IVM), also known as cultured meat, involves growing cells into muscle tissue to be eaten as food. The technology had its most high-profile moment in 2013 when a cultured burger was cooked and tasted in a press conference. Images of the burger featured in the international media and were circulated across the Internet. These images-literally marks on a two-dimensional surface-do important work in establishing what IVM is and what it can do. A combination of visual semiotics and narrative analysis shows that images of IVM afford readings of their story that are co-created by the viewer. Before the cultured burger, during 2011, images of IVM fell into four distinct categories: cell images, tissue images, flowcharts, and meat in a dish images. The narrative infrastructure of each image type affords different interpretations of what IVM can accomplish and what it is. The 2013 cultured burger images both draw upon and depart from these image types in an attempt to present IVM as a normal food stuff, and as 'matter in place' when placed on the plate. The analysis of individual images and the collection of images about a certain object or subject known as the imagescape-is a productive approach to understanding the ontology and promise of IVM and is applicable to other areas of social life. PMID- 27695203 TI - Estimating the health benefit of reducing indoor air pollution in a randomized environmental intervention. AB - Recent intervention studies targeted at reducing indoor air pollution have demonstrated both the ability to improve respiratory health outcomes and to reduce particulate matter (PM) levels in the home. However, these studies generally do not address whether it is the reduction of PM levels specifically that improves respiratory health. In this paper we apply the method of principal stratification to data from a randomized air cleaner intervention designed to reduce indoor PM in homes of children with asthma. We estimate the health benefit of the intervention amongst study subjects who would experience a substantial reduction in PM in response to the intervention. For those subjects we find an increase in symptom-free days that is almost three times as large as the overall intention-to-treat effect. We also explore the presence of treatment effects amongst those subjects whose PM levels would not respond to the air cleaner. This analysis demonstrates the usefulness of principal stratification for environmental intervention trials and its potential for much broader application in this area. PMID- 27695204 TI - Intracellular Organisms as Placental Invaders. AB - In this article we present a novel model for how the human placenta might get infected via the hematogenous route. We present a list of diverse placental pathogens, like Listeria monocytogenes or Cytomegalovirus, which are familiar to most obstetricians, but others, like Salmonella typhi, have only been reported in case studies or small case series. Remarkably, all of these organisms on this list are either obligate or facultative intracellular organisms. These pathogens are able to enter and survive inside host immune cells for at least a portion of their life cycle. We suggest that many blood-borne pathogens might arrive at the placenta via transportation inside of maternal leukocytes that enter the decidua in early pregnancy. We discuss mechanisms by which extravillous trophoblasts could get infected in the decidua and spread infection to other layers in the placenta. We hope to raise awareness among OB/GYN clinicians that organisms not typically associated with the TORCH list might cause placental infections and pregnancy complications.

AB - The focus of our laboratory's investigation is to study the direct-type DNA damage mechanisms resulting from gamma-ray and ion-beam radiation-induced free radical processes in DNA which lead to molecular damage important to cellular survival. This work compares the results of low LET (gamma-) and high LET (ion beam) radiation to develop a chemical track structure model for ion-beam radiation damage to DNA. Recent studies on protonation states of cytosine cation radicals in the N1-substituted cytosine derivatives in their ground state and 5 methylcytosine cation radicals in ground as well as in excited state are described. Our results exhibit a radical signature of excitations in 5 methylcytosine cation radical. Moreover, our recent theoretical studies elucidate the role of electron-induced reactions (low energy electrons (LEE), presolvated electrons (epre-), and aqueous (or, solvated) electrons (eaq-)). Finally DFT calculations of the ionization potentials of various sugar radicals show the relative reactivity of these species. PMID- 27695206 TI - The long-term outcomes after staged repair of exstrophy-epispadias complex. AB - INTRODUCTION: Classic bladder exstrophy (BE) is a rare malformation of the genito urinary tract affecting 1:50,000 to 1:100,000 live births. The surgical reconstruction of the BE-epispadias complex is challenging for the most experienced pediatric urologists, surgeons, and orthopedists. PURPOSE: To assess the success of staged reconstruction of the BE and long-term effects on the upper urinary tract, renal function, and continence. MATERIALS AND METHODS: This is retrospective study; between 1994 and 2013, 30 patients with BE have undergone stage 1 repair at the institute. Eighteen male patients have been operated for epispadias repair and thirteen patients have undergone Guy Leadbetter bladder neck reconstruction. Three patients required augmentation cystoplasty one child is continent after epispadias repair only and one child attained continence after single-stage repair. RESULTS: Hence, out of 17 patients, 14 are socially continent, four patients require clean intermittent self-catheterization for bladder emptying. Four patients, who are coming for regular follow-up, are awaiting continence procedure. Two patients who underwent augmentation cystoplasty are on hemodialysis for renal failure and one child has altered renal function. CONCLUSION: In our experience, the modern staged repair offers a low risk of renal scarring with acceptable continence opportunity with acceptable cosmetic appearance of external genitalia in the males and females. PMID- 27695207 TI - Scrotal abscess: Varied etiology, associations, and management. AB - AIM: To report a series of scrotal abscess, a rare problem, their etiology, and management. MATERIALS AND METHODS: A retrospective study of children who presented with scrotal abscess between January 2010 and March 2015, analyzed with respect to clinical features, pathophysiology of spread and management. RESULTS: Eight infants and a 3-year-old phenotypically male child presented with scrotal abscess as a result of abdominal pathologies which included mixed gonadal dysgenesis (MGD) [1]; three anorectal malformations with ectopic ureter [1], urethral stricture [1], and neurogenic bladder [1]; meconium peritonitis with meconium periorchitis [2], ileal atresia [1], and intra-abdominal abscess [1]; posturethroplasty for Y urethral duplication with metal stenosis [1] and idiopathic pyocele [1]. Transmission of the organism had varied routes include fallopian tube [1], urethra ejaculatory reflux [4], hematogenous [2], and the patent process of vaginalis [2]. Two of the nine required extensive evaluation for further management. Treating the predisposing pathology resolved scrotal abscesses in eight of nine patients, one of whom, required vasectomy additionally. Idiopathic pyocele responded to needle aspiration and antibiotics. CONCLUSION: Scrotal abscess needs a high index of suspicion for predisposing pathology, especially in infants. Laparoscopy is safe and effective in the management of the MGD and ectopic ureter. PMID- 27695209 TI - Intragastric pressure: Useful indicator in the management of congenital diaphragmatic hernia. AB - AIMS: To assess the role of measuring of intragastric pressure (IGP) during closure of congenital diaphragmatic hernia. MATERIALS AND METHODS: Thirty-two cases were included in the study (August 2008 to February 2014), and IGP has been measured intraoperatively during closure. RESULT: Patients were categorized in group A (15 patients), group B (14 patients) and group C (3 patients). In group C, IGP was more than 30 cm of water pressure and all of tehm required creation of ventral hernia and ventilator support. CONCLUSION: Measurement of IGP as an objective, noninvasive and simple method to evaluate intra-abdominal pressure and prevention of abdominal compartment syndrome and intraoperative IGP value determines the types of abdominal closure. PMID- 27695208 TI - Comparison of intravenous urography and magnetic resonance urography in preoperative evaluation of pelvi-ureteric junction obstruction in children. AB - AIMS: To compare intravenous urography (IVU) and magnetic resonance urography (MRU) in the preoperative evaluation of pelvi-ureteric junction obstruction (PUJO) in children. MATERIALS AND METHODS: A total of 35 children up to 10 years of age in whom unilateral or bilateral PUJO were suspected on ultrasonography were enrolled in this prospective study. All children underwent IVU and MRU, and the findings were compared. RESULTS: Of the 70 kidneys evaluated, 14 (20%) were not visualized on IVU because of nonexcretion of contrast, whereas all the 70 (100%) kidneys were visualized on MRU. On IVU, nephrogram was not visualized in 66 (94.2%) of the 70 kidneys, whereas MRU showed prompt and homogeneous nephrogram in 68 (97.1%) of the 70 kidneys. No evidence of PUJO was seen in 31 (44.2%) kidneys on both IVU and MRU. IVU showed PUJO in 26 (37.1%) kidneys, whereas MRU showed it in 38 (54.2%) kidneys. MRU detected two duplex systems that were missed on IVU. A focal renal lesion and two incidental extra renal abnormalities were detected on MRU, which were not visualized on IVU. CONCLUSION: MRU is better than IVU, especially in case of poorly functioning kidneys which are not visualized on IVU. MRU also provides anatomic details of the ureter and vessels with better evaluation of renal parenchyma. It also has an additional advantage of detecting incidental extra renal abnormalities, if present. PMID- 27695210 TI - Gluteal teratoma: A rare site of extragonadal teratoma. AB - Extragonadal teratomas are rarely encountered in infants and children. These tumors are reported in retroperitoneum, floor of the mouth, mediastinum, craniofacial region or even in the solid organs of the body. Most of the gluteal teratomas reported in the literature are in fact, lateralized sacrococcygeal teratomas. We are reporting a case of unilateral big gluteal teratoma in a 6-year old girl. The tumor did not have any connection with the sacrum or coccyx and was successfully removed. Histology showed well-differentiated bowel as well as fetiform structures.

PMID- 27695212 TI - Laparoscopic retrieval of unusual intra-abdominal foreign bodies in children. AB - Foreign body (FB) ingestion is a common problem among the pediatric population. On numerous occasions, the FB is left to pass out spontaneously without expecting any harm. There are instances when the FB is either to dangerous to be left alone, that is a button battery or a sharp object. There may be FB, which is either stuck in GIT or have migrated. The situation in these instances demand active intervention. The traditional option has been laparotomy and retrieval. We present here three cases where two needles and a belt buckle were removed by laparoscopy thus avoiding a laparotomy. These cases prove that laparoscopy should be the first choice for such kind of retrieval. These cases had a successful outcome with full recovery.

These are almost exclusively in urban centers. Consequently, people in rural areas, most of the African population, have poor or no access to neurosurgical care. We have recently pioneered rural neurosurgery in Nigeria. OBJECTIVES: This report details our initial experiences and the profile of neurosurgical admissions in our center. METHODS: A prospective observational study of all neurosurgical patients managed at a rural tertiary health institution in Nigeria from December 2010 to May 2012 was done. Simple descriptive data analysis was performed. RESULTS: A total of 249 males (75.2%) and 82 females (24.8%) were managed. The median age was 37 years (range: Day of birth - 94 years). Trauma was the leading cause of presentation with 225 (68.0%) and 35 (10.6%) having sustained head and spinal injuries, respectively. Operative intervention was performed in 54 (16.3%). Twenty-four (7.2%) patients discharged against medical advice, mostly for economic reasons. Most patients (208, 63.4%) had satisfactory outcome while 30 (9.1%) died. CONCLUSION: Trauma is the leading cause of rural neurosurgical presentations. There is an urgent need to improve access to adequate neurosurgical care in the rural communities. PMID- 27695225 TI - Chemical shift magnetic resonance imaging in differentiation of benign from malignant vertebral collapse in a rural tertiary care hospital in North India. AB - INTRODUCTION: Magnetic resonance imaging (MRI) is the modality of the first choice for evaluation of vertebral compression/collapse. Many MRI qualitative features help to differentiate benign from malignant collapse. We conducted this study to look for a quantitative difference in chemical shift values in benign and malignant collapse using dual-echo gradient echo in-phase/out-phase imaging. MATERIALS AND METHODS: MRI examinations of a total of 38 patients were retrospectively included in the study who had vertebral compression/collapse with marrow edema in which final diagnosis was available at the time of imaging/follow up. Signal intensity value in the region of abnormal marrow signal and adjacent normal vertebra was measured on in phase/out phase images. Signal intensity ratio (SIR) was measured by dividing signal intensity value on opposite phase images to that on in phase images. SIR was compared in normal vertebrae and benign and malignant vertebral collapse. RESULTS: There were 21 males and 17 females with mean age of 52.4 years (range 28-76 years). Out of total 38 patients, 18 were of benign vertebral collapse and 20 of malignant vertebral collapse. SIR in normal vertebrae was 0.30 +/- 0.14, 0.67 +/- 0.18 in benign vertebral collapse, and 1.20 +/- 0.27 in malignant vertebral collapse with significant difference in SIR of normal vertebrae versus benign collapse (P < 0.01) and in benign collapse versus malignant collapse (P < 0.01). Assuming a cutoff of <0.95 for benign collapse and >=0.95 for malignant collapse, chemical shift imaging had a sensitivity of 90% and specificity of 94.4%. CONCLUSION: Chemical shift imaging is a rapid and useful sequence in differentiating benign from malignant vertebral collapse with good specificity and sensitivity. PMID- 27695226 TI - Longitudinal assessment of depression, stress, and burnout in medical students. AB - BACKGROUND: Medical students can and do suffer from mental disorders is a concept yet to get wide acceptance. There are few studies comprehensively evaluating depression, stress, and burnout in medical students, especially in a longitudinal way in India. The current study aims to assess the impact of medical education on the development of psychological morbidities and the role of personality. MATERIALS AND METHODS: First-year medical students of a leading medical college of India were enrolled on admission and given anonymized, validated, self administered questionnaires assessing depression, stress, burnout, and personality. This was repeated at the end of 1st year. Data were analyzed independently as questionnaires were anonymized. RESULTS: We found that 1st year of medical college showed a significantly increasing depression (P < 0.01) and stress (P < 0.01). Overall burnout did not increase significantly. However, only disengagement dimension of burnout increased significantly. Personalities with weak capacity to adjust had a significant positive correlation with depression (r = 0.277, P < 0.001) and stress scores (r = 0.210, P = 0.008). However, burnout did not correlate with any of the personality dimensions. CONCLUSION: Right from the 1st year of medical education students perceive high-stress levels and have a high risk of depression. Burnout starts to creep in at least in the form of disengagement. This study provides a sound groundwork for planning interventions to reduce student's mental morbidity and avoid burnout. PMID- 27695227 TI - Public knowledge and attitudes toward epilepsy in Majmaah. AB - OBJECTIVES: Epilepsy is very common in the Kingdom of Saudi Arabia, occurring in 6.54 out of every 1000 individuals. The current study was conducted to determine the level of public awareness of and attitudes toward epilepsy in the city of Majmaah, Saudi Arabia. SUBJECTS AND METHODS: This descriptive study was conducted in Majmaah, Saudi Arabia. The study population included respondents derived from preselected public places in the city. Stratified random sampling was used, and the sample size was made up of 706 individuals. A structured questionnaire was used for data collection from respondents after receiving their verbal consent. The data were analyzed using SPSS version 2.0. Ethical approval was obtained from the Ethics Committee of Majmaah University. RESULTS: The results showed that 575 (81.4%) of the respondents had heard or read about epilepsy. Almost 50% of the respondents knew someone who had epilepsy, and 393 (55.7%) had witnessed what they believed to be a seizure. Results showed that 555 (78.6%) respondents believed that epilepsy was neither a contagious disease nor a type of insanity. It was found that 335 (47.5%) stated that epilepsy was a brain disease, and almost one-quarter of the respondents said that the manifestation of an epileptic episode is a convulsion. Regarding attitude, 49% and 47.3% of respondents stated that they would not allow their children to interact with individuals with epilepsy and would object to marrying an individual with epilepsy, respectively. CONCLUSION: Although knowledge about epilepsy is improving, it is still not adequate. The study showed that the attitude toward epilepsy is poor. PMID- 27695228 TI - Knowledge, attitude, and practice of stroke among high school students in Nepal. AB - BACKGROUND: Baseline stroke knowledge in a targeted population is indispensable to promote the effective stroke education. We report the baseline knowledge, attitude, and practice (KAP) of high school students with respect to stroke from Nepal. MATERIALS AND METHODS: A self-structured questionnaire survey regarding KAP about stroke was conducted in high school students of 33 schools of Bharatpur, Nepal. Descriptive statistics including Chi-square test was used, and the significant variables were subjected to binary logistic regression. RESULTS: Among 1360 participants, 71.1% had heard or read about stroke; 30.2% knew someone with stroke. 39.3% identified brain as the organ affected. Sudden onset limb/s weakness/numbness (72%) and hypertension (74%) were common warning symptom and risk factor identified. 88.9% would take stroke patients to a hospital. Almost half participants (55.5%) felt ayurvedic treatment be effective. 44.8% felt stroke as a hindrance to a happy life and 86.3% believed that family care was helpful for early recovery. Students who identified at least one risk factor were 3.924 times (P < 0.001, confidence interval [CI] = 1.867-8.247) or those who identified at least one warning symptom were 2.833 times (P <= 0.023, CI = 1.156 6.944) more likely to take stroke patients to a hospital. CONCLUSION: KAP of high school Nepalese students regarding stroke was satisfactory, and the students having knowledge about the risk factors and warning symptoms were more likely to take stroke patients to a hospital. However, a few misconceptions persisted. PMID- 27695229 TI - Ki-67 immunostaining in astrocytomas: Association with histopathological grade - A South Indian study. AB - BACKGROUND: Astrocytomas are the most common primary tumor of the central nervous system. The distinction between different tumor grades can be tested despite criteria given by the World Health Organization (WHO). Ki-67 is a potent biological marker used in grading of astrocytomas, which estimates growth of the neoplasm quantitatively and will help in predicting prognosis accurately. OBJECTIVES: The aim of this was to study the proliferative activity using Ki-67 immunostaining and to assess the relationship of Ki-67 staining with the histopathological grading of astrocytomas. PATIENTS AND METHODS: Thirty cases of histologically proven astrocytomas were studied. The histopathological grade was assessed using the 2007 WHO criteria. Immunohistochemistry for Ki-67 was done on paraffin-embedded wax sections. P < 0.05 was considered statistically significant. RESULTS: Thirty cases of astrocytomas studied showed a male preponderance (M:F = 1.72:1) with a mean age of 48.1 years. Of these, Grade I, (n = 1, 3.33%), Grade II, (n = 7, 23.3%), Grade III (n = 6, 20%), and Grade IV (n = 16, 53.3%) astrocytomas were analyzed. The mean Ki-67 labeling index (LI) in Grades I, II, III, and IV was 0.02, 0.81, 9.14, and 17.81, respectively. Statistically significant difference was seen in the Ki-67 LI of low-grade (Grade II) and high-grade astrocytomas (Grades III and IV). There was concordance between histopathological grading and Ki-67 LI in 27 (90%) and discordance in 3 (10%) cases. CONCLUSION: Ki-67 LI varies considerably in different grades of astrocytomas and considerable overlaps can be observed between them. It can be of great help in situations where there is a lack of correlation between clinical parameters and histopathological diagnosis. Determination of Ki-67 LI should constitute a part of routine investigations in patients with astrocytomas. PMID- 27695230 TI - Epidemiology, clinical characteristics and outcomes of traumatic brain injury: Evidences from integrated level 1 trauma center in India. AB - INTRODUCTION: Traumatic brain injury (TBI) is a leading cause of mortality, morbidity, disability, and socioeconomic losses in the Indian subcontinent. However, for policymaking and research, there is a lack of reliable and larger data in our settings. AIMS AND OBJECTIVES: To evaluate and describe the epidemiological, clinical characteristics, and outcomes of patients with TBI in a Level 1 Trauma Center in India. MATERIALS AND METHODS: In this retrospective study, all patients with moderate or severe TBI, based on emergency department Glasgow Coma Scale, admitted to neurosurgery Intensive Care Unit (ICU) during May 2010-July 2012 were evaluated to provide detailed information on TBI-related variables and outcomes using descriptive statistics. RESULTS: Among the 1527 patients with moderate or severe TBI patients with mean age 32.15 +/- 16.76 years (range: 1-90) and male:female ratio 6.5:1, 1281 (83.89%) had severe TBI. The majority of cases took place in the age group of 21-40 years (50.24%) with the most common mode of injury as road traffic accidents (RTAs) (64.96%). Surgical intervention (craniotomy) was done in 49.12% of patients. About 34.58% (n = 528) patients died in hospital, and 67.21% (n = 701) had unfavorable outcome at 6 months. CONCLUSIONS: This is the first study of its kind from the Indian subcontinent that gives data on the admission characteristics, mortality, and 6 months outcome of such patients. Most of the injuries occurred due to RTAs, more common among the economic productive age groups and mostly in males with a high rate of mortality and unfavorable outcome. PMID- 27695231 TI - Human epidermal growth factor receptor 2/neu protein expression in meningiomas: An immunohistochemical study. AB - BACKGROUND: Meningiomas are common slow-growing primary central nervous system tumors that arise from the meningothelial cells of the arachnoid and spinal cord. Human epidermal growth factor receptor 2 (HER2) or HER2/neu (also known as c erbB2) is a 185-kD transmembrane glycoprotein with tyrosine kinase activity expressed in meningiomas and various other tumors. It can be used in targeted therapy for HER2/neu positive meningiomas. AIM: To correlate the expression of HER2/neu protein in meningiomas with gender, location, histological subtypes, and grade. MATERIALS AND METHODS: It was 31/2 years prospective (March 2010-October 2011) and retrospective (May 2008-February 2010) study of histopathologically diagnosed intracranial and intraspinal meningiomas. Clinical details of all the cases were noted from the computerized hospital information system. Immunohistochemistry for HER2/neu protein was performed along with scoring. Statistical analysis was done using Chi-square test to look for any association of HER2/neu with gender, location, grade, and various histological subtypes of meningiomas at 5% level of significance. RESULTS: A total of 100 cases of meningiomas were found during the study period. Of which, 80 were Grade I, 18 were Grade II, and 2 were Grade III meningiomas as per the World Health Organization 2007 criteria. The female-male ratio was 1.9:1 and the mean age was 47.8 years. HER2/neu protein was expressed in 75% of Grade I and 72.2% of Grade II and none of Grade III meningiomas. About 72.7% brain invasive meningiomas showed HER2/neu immunopositivity. CONCLUSION: HER2/neu protein was expressed in 73% of meningiomas. Statistically significant difference of HER2/neu expression was not seen between females and males of Grade I and Grade II/III meningiomas, intracranial and spinal tumors, Grade I and Grade II/III cases, and various histological subtypes of meningiomas. PMID- 27695232 TI - Nummular headache: Clinico-epidemiological features in South Indian population. AB - CONTEXT: Nummular headache (NH) is a primary disorder characterized by head pain exclusively felt in a small-rounded area typically 2-6 cm in diameter. AIMS: The aim of this review is to study the clinical and epidemiological features of NH in a patient population of South India and to compare this with that of described in the international literature. SETTINGS AND DESIGN: A prospective, observational study conducted in a tertiary care center. MATERIALS AND METHODS: Patients attending the medicine and neurology outpatient departments of a tertiary referral hospital in South India diagnosed to have NH as per the International Classification of Headache Disorders 3 beta (2013) criteria were studied over 30 months. All of the patients had a normal neurological examination. Neuroimaging findings were normal, except in one patient. RESULTS: A total of 19 females and 10 males were studied. The mean age of onset was 47.62 years (range 36-60). The duration of headache varied from a minimum of 3 months to a maximum of 5 years, with a mean of 24.17 months. The site of headache was predominantly in the parietal area 15 (51.72%), followed by the occipital area 7 (24.13%). The mean diameter of the affected area was 3.23 cm. The intensity of the headache proved to be mild to moderate with a mean visual analog scale score of 5.03. The quality of pain was mainly felt as burning dysesthesia 12 (41.38%). In the majority of patients, i.e. 21 (72.41%), pain was chronic and continuous. None of the patients had any significant trophic change even though paresthesias, dysesthesias, and allodynia were reported by a significant minority of patients, i.e. 9 (31.03%). Only one (3.45%) patient gave a history of head injury. Ten (34.48%) out of 29 patients had other types of concurrent headaches; the majority of which proved to be migrainous, i.e. 7 (24.14%), 2 patients (6.89%) with tension headache, and 1 patient (3.45%) with trigeminal neuralgia. CONCLUSION: Our study proves the existence of the newly described primary headache syndrome called NH in South Indian population. In comparing our results with the international literature, the number of similarities is much greater than the differences. The etiology of pain in our series appeared to be primarily peripheral with a role for central pain sensitization in some cases due to a variety of concurrent central causes of head pain. PMID- 27695233 TI - Evaluation of pituitary function in cases with the diagnosis of pediatric mild traumatic brain injury: Cross-sectional study. AB - BACKGROUND: This study was to determine whether pituitary dysfunction occurs after head trauma in children or not and which axis is affected more; to define the association of pituitary dysfunction with the severity of head trauma and duration time after the diagnosis of head trauma. MATERIALS AND METHODS: In this study, 24 children who were diagnosed with head trauma were evaluated regarding pituitary dysfunction. In all cases, after 12 h fasting, serum cortisol, fT3, fT4, thyroid-stimulating hormone, prolactin, insulin-like growth factor-1, serum sodium, urine density, follicle-stimulating hormone, luteinizing hormone, in female cases E2, in male cases, TT levels were determined. RESULTS: Mean age of children was 9.5 +/- 3.1 years, 14 children (58.3%) had mild, 9 children (37.5%) had moderate, and 1 children (4.2%) had severe head trauma according to the Glasgow coma scale. Mean duration time after head trauma was 29.4 +/- 9.8 months. In all cases, no pathologic condition was determined in the pituitary hormonal axis. In one children (4.2%), low basal cortisol level was found. There were no children with hormonal deficiency in this study. CONCLUSION: Although pituitary dysfunction after head trauma may develop in the early period, some may present in the late period; therefore, all cases should be followed up at outpatient clinics for a longer period. PMID- 27695235 TI - Comparative analysis of pedicle screw versus hybrid instrumentation in adolescent idiopathic scoliosis surgery. AB - INTRODUCTION: Adolescent idiopathic scoliosis is the most common type of scoliosis. A Cobb angle of 50 degrees will progress beyond the age of spinal maturity. Surgery over bracing is advised at a Cobb angle above or equal to 50 degrees . The aim of surgery is to bring the Cobb angle down below 50 degrees to prevent reprogression as well as improve the quality of life. The objective of the study is to analyze the efficacy and significance in lifestyle improvement of pedicle screw-only fixation system versus the more common hybrid instrumentation system used for the surgical treatment of adolescent idiopathic scoliosis. MATERIALS AND METHODS: A prospective cohort study was conducted involving two groups of patients were included in the study. One group was operated with pedicle screw-only method while the other with hybrid instrumentation system. The pre- and post-operative Cobb's angles were taken across a follow-up of 4 years. An SRS-30 questionnaire was given in a yearly follow-up to assess the lifestyle improvement of the patient. RESULTS: Pedicle screw-only method was significantly more effective in reducing Cobb's angle (P = 0.0487). It was showed less loss of correction (P = 0.009) pedicle screw-only surgery was also better at reducing thoracic curves (P = 0.001). There seemed a better recovery time with pedicle screw surgery (P = 0.003). CONCLUSION: Pedicle screws are more effective and durable than hybrid systems at when treating adolescent idiopathic scoliosis. PMID- 27695234 TI - Role of ankle foot orthosis in improving locomotion and functional recovery in patients with stroke: A prospective rehabilitation study. AB - OBJECTIVE: To study role of ankle foot orthosis (AFO) in improving locomotion and functional recovery after stroke. SETTING: Neurological Rehabilitation Department of a university research tertiary hospital. PATIENTS AND METHODS: AFO and activity based rehabilitation. MAIN OUTCOME MEASURES: Distance (meters) covered during the 6-minute walk test (6MWT) and speed (meter/second) during the 10-meter walk test. Functional abilities assessed using Functional Independence Measure (FIM(r)). RESULTS: Twenty-six patients (21 male) with stroke (mean duration 196.7 days, range 45-360 days) and mean age of 41.6 years (range 18-65 years, standard deviation [SD] 12.5) were included. Fourteen had right hemiplegia. The mean length of stay in the unit was 26.5 days (range 18-45 days, SD 5.5). All patients had equinus deformity with spastic foot drop and were provided with AFO. Walking endurance with 6MWT was 90 m on admission (without AFO). At discharge, it improved to 174 m with AFO and 121 m without AFOs (P < 0.001-with and without AFO at discharge). Walking speed improved from 0.4 m/s (admission) to 0.51 m/s with AFO, P = 0.004 and 0.45 m/s without AFO, P = 0.015) at discharge. Nine patients (34.6%) had clinically important difference-minimal clinically important difference (>0.16 m/s speed gain; >50 m endurance gain) at discharge. The mean FIM(r) score on admission was 84.3 +/- 18.6. At discharge FIM(r) improved to 101.9 +/- 13.7 (P < 0.001). CONCLUSIONS: Use of AFOs improve gait parameters significantly in only one-third stroke patients in the study when combined with activity-based inpatient-rehabilitation. PMID- 27695236 TI - Clinical features, risk factors, and outcome of cerebral venous thrombosis in Tehran, Iran. AB - INTRODUCTION: Despite increasing the use of magnetic resonance imaging (MRI), cerebral venous sinus thrombosis (CVST) has remained an under-diagnosed condition. In this study, characteristics and frequency of various risk factors of CVST patients in a tertiary referral hospital were closely assessed. METHODS: Patients with an unequivocal diagnosis of CVST confirmed by MRI and magnetic resonance venography during 6 years of the study were included. All data from the onset of symptoms regarding clinical signs and symptoms, hospital admission, seasonal distribution, medical and drug history, thrombophilic profile, D-dimer, neuroimaging, cerebrospinal fluid findings, mortality, and outcome were collected and closely analyzed. RESULT: A total of 53 patients with female to male ratio of 3.07 and mean age of 33.7 years were included in the study. Headache and papilledema were the most frequent clinical features (44 and 36 patients, respectively). An underlying disease (diagnosed previously or after admission) was the most common identified risk factor for CVST in both females and males (21 patients). A total of 15 women used the oral contraceptive pill (OCP) where 12 of them had simultaneously other predisposing factors. Overall, 19 patients (36%) had more than one contributing factor. D-dimer had a sensitivity of 71.4% in CVST patients. The mortality of patients in this study was 3.7% (n = 2). Focal neurologic deficit and multicranial nerve palsy were associated with poor outcome which defined as death, recurrence, and massive intracranial hemorrhage due to anticoagulation (P = 0.050 and 0.004, respectively). CONCLUSION: Unlike most of the CVST studies in which OCP was the main factor; in this study, an underlying disease was the most identified cause. Considering the high probability of multiple risk factors in CVST that was shown by this study, appropriate work up should be noted to uncover them. PMID- 27695240 TI - Morvan's syndrome with anti contactin associated protein like 2 - voltage gated potassium channel antibody presenting with syndrome of inappropriate antidiuretic hormone secretion. AB - Morvan's syndrome is a rare autoimmune disorder characterized by triad of peripheral nerve hyperexcitability, autonomic dysfunction, and central nervous system symptoms. Antibodies against contactin-associated protein-like 2 (CASPR2), a subtype of voltage-gated potassium channel (VGKC) complex, are found in a significant proportion of patients with Morvan's syndrome and are thought to play a key role in peripheral as well as central clinical manifestations. We report a patient of Morvan's syndrome with positive CASPR2-anti-VGKC antibody having syndrome of inappropriate antidiuretic hormone as a cause of persistent hyponatremia. PMID- 27695239 TI - Surgical resection of low-grade gliomas in eloquent areas with the guidance of the preoperative functional magnetic resonance imaging and craniometric points. AB - OBJECTIVES: Surgical resection of low-grade gliomas (LGGs) in eloquent areas is one of the challenges in neurosurgery, using assistant tools to facilitate effective excision with minimal postoperative neurological deficits has been previously discussed (awake craniotomy and intraoperative cortical stimulation); however, these tools could have their own limitations thus implementation of a simple and effective technique that can guide to safe excision is needed in many situations. MATERIALS AND METHODS: The authors conducted a retrospective analysis of a prospectively collected data of 76 consecutive surgical cases of LGGs of these 21 cases were situated in eloquent areas. Preoperative functional magnetic resonance imaging (fMRI), pre- and post-operative MRI with volumetric analysis of the tumor size was conducted, and intraoperative determination of the craniometric points related to the tumor (navigation guided in 10 cases) were studied to evaluate the effectiveness of the aforementioned tools in safe excision of the aforementioned tumors. RESULTS: Total-near total excision in 14 (66.67%) subtotal in 6 (28.57%), and biopsy in 1 case (4.57%). In long-term follow-up, only one case experienced persistent dysphasia. CONCLUSION: In spite of its simplicity, the identification of the safe anatomical landmarks guided by the preoperative fMRI is a useful technique that serves in safe excision of LGGs in eloquent areas. Such technique can replace intraoperative evoked potentials or the awake craniotomy in most of the cases. However, navigation-guided excision might be crucial in deeply seated and large tumors to allow safe and radical excision. PMID- 27695238 TI - Duration of suicide process among suicide attempters and characteristics of those providing window of opportunity for intervention. AB - BACKGROUND: There is limited cross-cultural literature on the duration of suicide process among attempters. AIMS: The primary aim was to assess the duration of suicide process among suicide attempters attending the Crisis Intervention Clinic. We also aimed to identify the characteristics of those who reported a longer duration for this process. METHODS: In this retrospective record-based study, we collected the duration of the suicidal process from the records of all the suicide attempters evaluated over a 3-year period (n = 319). Attempters were divided into four groups based on the quartile value of the duration of the suicidal process. For analysis, the characteristics of those in the last quartile with suicide process time of >120 min (n = 75) were compared with those in the first three (n = 244). Those in the last quartile were considered to provide a window of opportunity for intervention. RESULTS: The median time for the suicidal process was 30 min (interquartile range of 5 min to 120 min). Seventy-five (23.5%) subjects belonged to the fourth quartile (duration of suicide process >120 min). A significant proportion of them came from urban areas (P = 0.011), had a diagnosis of mood disorder (P = 0.028), had visited a health professional in the recent past (P = 0.015), and had lower rates of attempt under intoxication (P = 0.005). A lesser proportion of them showed problem-focused disengagement style of coping strategy (P = 0.015). CONCLUSIONS: The suicide process time among Indian suicide attempters is short. However, a quarter of them has suicide process duration of 2 h which provides some scope for intervention. Individual and community level interventions need further evaluation for their potential efficacy in preventing the progress of the suicidal process. PMID- 27695241 TI - Commentary. PMID- 27695237 TI - Determining rural risk for aneurysmal subarachnoid hemorrhages: A structural equation modeling approach. AB - An aneurysmal subarachnoid hemorrhage (aSAH) carries a high disability burden. The true impact of rurality as a predictor of outcome severity is unknown. Our aim is to clarify the relationship between the proposed explanations of regional and rural health disparities linked to severity of outcome following an aSAH. An initial literature search identified limited data directly linking geographical location, rurality, rural vulnerability, and aSAH. A further search noting parallels with ischemic stroke and acute myocardial infarct literature presented a number of diverse and interrelated predictors. This a priori knowledge informed the development of a conceptual framework that proposes the relationship between rurality and severity of outcome following an aSAH utilizing structural equation modeling. The presented conceptual framework explores a number of system, environmental, and modifiable risk factors. Socioeconomic characteristics, modifiable risk factors, and timely treatment that were identified as predictors of severity of outcome following an aSAH and within each of these defined predictors a number of contributing specific individual predictors are proposed. There are considerable gaps in the current knowledge pertaining to the impact of rurality on the severity of outcome following an aSAH. Absent from the literature is any investigation of the cumulative impact and multiplicity of risk factors associated with rurality. The proposed conceptual framework hypothesizes a number of relationships between both individual level and system level predictors, acknowledging that intervening predictors may mediate the effect of one variable on another. PMID- 27695242 TI - Cystic dilation of the ventriculus terminalis. AB - The ventriculus terminalis (VT) is a virtual cavity of the conus medullaris that appears during embryonic life. We presented a case with the cystic dilation of the ventriculus terminalis (CDVT) in a symptomatic patient. A 66-year-old female suffered from disturbance while walking evolving for the past 2 years. An MR image revealed a cystic dilatation of ventriculus terminalis. The patient experienced marked improvement of lower extremity strength by a fenestration of cyst and cyst-subarachnoid shunt. Treatment for asymptomatic patients seems to be the best conducted conservatively, whereas patients with focal neurological deficits seem to be best handled surgically.

This case highlights the ever-expanding phenotypic heterogeneity of the SCA's in general and SCA1 in particular. PMID- 27695244 TI - Cardiac arrhythmia in Wilson's disease: An oversighted and overlooked entity! AB - Wilson's disease is a multisystem disorder which manifests with hepatic, neurological, musculoskeletal, hematological, renal, and cardiac symptoms. The hepatic and neurological manifestations often overshadow the other system involvement including cardiac symptoms and signs, which may prove fatal. We report a case of a young female who presented with progressive parkinsonian features and dystonia for around 4 months followed 2 months later by the complaint of episodes of light-headedness. She was diagnosed to have Wilson's disease based on the presence of Kayser-Fleischer ring and laboratory parameters of copper metabolism. Electrocardiography of the patient incidentally revealed 2nd degree Mobitz type-1 atrioventricular block explaining her episodes of light headedness. She was started on penicillamine and trihexyphenidyl. The heart block improved spontaneously. Cardiac autonomic function tests including blood pressure response to standing and heart rate response to standing were observed to be normal. We review the literature on cardiac manifestations of Wilson's disease and emphasize that patients with Wilson's disease should be assessed for cardiac arrhythmia and cardiac dysfunction as these may have therapeutic and prognostic implications.

AB - Meningitis caused by varicella zoster virus (VZV) is quite rare among young immunocompetent adults though immunocompromised patients are often seen to be affected by reactivation of VZV presenting with primary clinical features of dermatomal rashes and neurological sequelae. Here, we report the clinical scenario of a young, healthy male who had presented with fever, headache, and onset of dermatomal rashes later than the fever and was eventually diagnosed to be a case of VZV meningitis. We would like to highlight the fact that even young immunocompetent patients though rarely, might contract VZV meningitis and clinicians should have a high index of suspicion and keen eyes to catch the more obvious features of VZV infection on complete physical examination and must not harbor any reservations in ordering polymerase chain reaction for VZV DNA or initiating aggressive antiviral therapy.

PMID- 27695249 TI - The use of intraoperative computed tomography navigation in pituitary surgery promises a better intraoperative orientation in special cases. AB - OBJECTIVE: The safety of endoscopic skull base surgery can be enhanced by accurate navigation in preoperative computed tomography (CT) and magnetic resonance imaging (MRI). Here, we report our initial experience of real-time intraoperative CT-guided navigation surgery for pituitary tumors in childhood. MATERIALS AND METHODS: We report the case of a 15-year-old girl with a huge growth hormone-secreting pituitary adenoma with supra- and perisellar extension. Furthermore, the skull base was infiltrated. In this case, we performed an endonasal transsphenoidal approach for debulking the adenoma and for chiasma decompression. We used an MRI neuronavigation (Medtronic Stealth Air System) which was registered via intraoperative CT scan (Siemens CT Somatom). Preexisting MRI studies (navigation protocol) were fused with the intraoperative CT scans to enable three-dimensional navigation based on MR and CT imaging data. Intraoperatively, we did a further CT scan for resection control. RESULTS: The intraoperative accuracy of the neuronavigation was excellent. There was an adjustment of <1 mm. The navigation was very helpful for orientation on the destroyed skull base in the sphenoid sinus. After opening the sellar region and tumor debulking, we did a CT scan for resection control because the extent of resection was not credible evaluable in this huge infiltrating adenoma. Thereby, we were able to demonstrate a sufficient decompression of the chiasma and complete resection of the medial part of the adenoma in the intraoperative CT images. CONCLUSIONS: The use of intraoperative CT/MRI-guided neuronavigation for transsphenoidal surgery is a time-effective, safe, and technically beneficial technique for special cases.

AB - BACKGROUND: Galphimia glauca is an evergreen shrub found across peninsular India, belonging to family Malpighiaceae. OBJECTIVE: The objective of this study was to assess the in vivo depressant effects and muscle coordination activity of G. glauca stem methanol extract (GGSME). MATERIALS AND METHODS: The stem methanol extract was administered in Swiss albino mice in 1 day to study the central nervous system (CNS) depressant and muscle coordination activity employing animal models such as sodium pentobarbital-induced sleep test, hole-board test, open field test, pentylenetetrazole (PTZ)-induced convulsions, picrotoxin-induced convulsions, grip strengthening test in mice, and Rota-rod test. RESULTS: The LD50 of GGSME was found to be >2000 mg/kg body weight (b.w.). Mice treated with stem methanol extract at 100, 200, and 400 mg/kg, b.w. doses extended the sleeping time induced by sodium pentobarbital (40 mg/kg. b.w., i.p.). The stem methanol extract at 400 mg/kg dose showed a significant (P <= 0.001) dose dependent decrease in the number of rears and head dipping number in the hole board test. The extract exhibited a significant (P <= 0.001) effect on the ambulatory behavior of mice in the open field test and also extended the onset of seizures induced by PTZ (90 mg/kg b.w., i.p.) and picrotoxin (10 mg/kg, b.w., i.p.). The extract also exhibited significant (P <= 0.001) effects on muscle coordination in rota-rod and grip strengthening test in mice. CONCLUSION: The study results conclude that the GGSME has a potential CNS depressant and muscle relaxant effects compared to the standard drugs. SUMMARY: Anxiety is implicated in the number of psychiatric disordersIn vivo depressant activity is studied employing animal models like Sodium pentobarbital-.induced sleep test, Hole-board test, Open field test, Pentylenetetrazole induced convulsions and Picrotoxin induced convulsions tests.Muscle coordination activity is studied employing animal models like Grip strengthening test in mice and Rota-.rod test.The GABAergic system plays a significant role in CNS depressant and muscle relaxant effects.The study proves the traditional claims of the plant used in the treatment of phobia, panic, stress, anxiety and it is as well used in producing a calming effect on the nerves.

Given the many side effects of modern medicine, the initial acquisition of fewer side effects, and medication of indigenous drugs, it should be considered as a better alternative for the treatment of peptic ulcer. OBJECTIVE: To assess antiulcer and antioxidant activity of ethanol extract of Barleria gibsoni (EBG) Dalz. leaves in ulcer-induced rats and in vitro antioxidants method, respectively. MATERIALS AND METHODS: Ethanol EBG was screened for antiulcer activity in pylorus ligation-induced ulcer models in Wistar rats. In vitro antioxidant activity of the extracts was tested using 2,2-diphenyl-1 picrylhydrazyl (DPPH), nitric oxide (NO) radical scavenging activity. Total phenol and flavonoid content in the extracts were determined spectrophotometrically. RESULTS: Oral administration of ethanol extract of leaves at doses of 250, 500 mg/kg p.o. reduced significant gastric lesions induced by pylorus ligation-induced ulcer as compared to standard omeprazole (20 mg/kg p.o.). The IC50 values were found to be 150 MUg/mL in leaves extract. The ethanol extracts showed good antioxidant capacity in DPPH radical scavenging assay and NO radical scavenging activity when compared to standard. The total phenolic content using Folin-Ciocalteu reagent estimated in 1 mg of leaves extracts was 368 MUg and 481 MUg with gallic acid equivalent and also the total flavonoid content found to be 240 and 410 MUg, respectively, with quercetin equivalence. CONCLUSION: These findings suggest that the leaves of B. gibsoni possessed antiulcer potential and antioxidant compared to standard. This is the first ever report of antiulcer and antioxidant activities in B. gibsoni (Acanthaceae). SUMMARY: In vivo antiulcer and in vitro antioxidant activity of Barleria gibsoni was evaluated.Soxhelt extraction was carried out and extracts were subjected to qualitative phytochemical analysis. Extract obtained by Soxhlation showed higher total phenolic and flavonoid contents.EBG showed DPPH and Nitric oxide scavenging activity indicating its strong antioxidant potential.On pylorus ligation accumulated secretions and the related ulcers confirm gastric acid output to be the basic cause of gastric ulcers. Ethanol extract of leaves attenuated the gastric volume, free acidity, total acidity and ulcer index thus showing the anti secretory mechanism.The results of the histopathological investigation of Barleria gibsoni leaves for antiulcer effects using pylorus ligation induced ulcer model in rats laid credence to traditional use of the plant leaves in ulcer treatment. The ethanol extract of leaves demonstrated increase in percentage preventive index compared to omeprazole respectively. From the present study results reveals the antiulcer activity of ethanol extract leaves which is comparable to that of Omeprazole.

PMID- 27695260 TI - Probing Regenerative Potential of Moringa oleifera Aqueous Extracts Using In vitro Cellular Assays. AB - BACKGROUND: Molecules stimulating regeneration and proliferation of cells are of significance in combating ailments caused due to tissue injury, inflammation, and degenerative disorders. Moringa oleifera is one of the most valued food plants having the profile of important nutrients and impressive range of medicinal uses. OBJECTIVE: To evaluate the potential of M. oleifera aqueous leaf and flower extracts to promote the proliferation of cells and explore their effect on cancer cell lines for assessment of safety. MATERIALS AND METHODS: Aqueous leaf and flower extracts of M. oleifera were investigated for effect on rat-derived primary fibroblast, mesenchymal stem cells (MSCs), and cancer cell lines using cell proliferation assay. They were also tested and compared for wound healing, angiogenesis, and hepatoprotective effect using in vitro assays. RESULTS: Statistically significant increase in the proliferation of primary rat fibroblast, MSCs, and angiogenesis was observed after treatment with aqueous flower extract. The aqueous leaf extract determined a comparatively moderate increment in the proliferation of MSCs and angiogenesis. It however showed prominent cytotoxicity to cancer cell lines and a significant hepatoprotective effect. CONCLUSION: A very clear difference in response of the two extracts to different types of cells was detected in this study. The aqueous flower extract exhibited a higher potential to stimulate cell proliferation while not exerting the same effect on cancer cell lines. The leaf extract on the other hand, had a prominent antitumor and hepatoptotective effects. SUMMARY: Moringa oleifera flower extract showed significant ability to promote proliferation of rat fibroblast and mesenchymal stem cells. The extract also had prominent angiogenic and hepatoprotective effects.The extract did not influence proliferation of cancer cell lines indicating its safety for human consumption and use in pharmaceuticals.The Moringa oleifera leaf extract showed relatively less potential to stimulate cells but had prominent cytotoxic effect on cancer cell lines.

PMID- 27695262 TI - Kayeassamin A Isolated from the Flower of Mammea siamensis Triggers Apoptosis by Activating Caspase-3/-8 in HL-60 Human Leukemia Cells. AB - BACKGROUND: Mammea siamensis (Miq.) T. Anders. is used as a medicinal plant in Thailand and has several traditional therapeutic properties. In a previous study, we isolated eight compounds from the flower of M. siamensis and demonstrated that kayeassamin A (KA) exhibited potent antiproliferative activity against human leukemia and stomach cancer cell lines. OBJECTIVE: In this study, we investigated the effect of KA on cell viability and apoptotic mechanisms in HL-60 human leukemia cells. MATERIALS AND METHODS: Cell viability was measured by 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Nuclear morphology and DNA fragmentation were observed using Hoechst 33258 staining and agarose gel electrophoresis, respectively. The sub-G1 phase of cells was analyzed by flow cytometry after the cellular DNA had been stained with propidium iodide. The protein levels of poly (ADP-ribose) polymerase (PARP) and caspases were determined by Western blotting. RESULTS: KA exhibited a significant cytotoxic effect in a dose- and time-dependent manner, and induced chromatin condensation, DNA fragmentation, and sub-G1 phase DNA content, known as molecular events associated with the induction of apoptosis. In addition, KA strongly induced the activation of PARP and caspase-3 and -8, with weak caspase-9 activation. Furthermore, KA-induced DNA fragmentation was abolished by pretreatment with z VAD-FMK (a broad caspase inhibitor), z-DEVD-FMK (a caspase-3 inhibitor), and z IETD-FMK (a caspase-8 inhibitor), but not by z-LEHD-FMK (a caspase-9 inhibitor) pretreatment. CONCLUSION: These results indicate that KA triggers apoptotic cell death by activation of caspase-3 and -8 in HL-60 cells. SUMMARY: Kayeassamin A (KA) isolated from the flower of Mammea siamensis exhibited a significant cytotoxic effect in HL-60 human leukemia cells. KA triggers apoptotic cell death by activating caspase-3/-8.

PMID- 27695264 TI - Chemical Characterization and Cytoprotective Effect of the Hydroethanol Extract from Annona coriacea Mart. (Araticum). AB - INTRODUCTION: Annona coriacea Mart. (araticum) is a widely distributed tree in the cerrado. Its value is attributed principally to the consumption of its fruit which possesses a large nutritive potential. The objective was to identify the chemical profile and evaluate the antimicrobial and cytoprotective activity of the hydroethanol extract of A. coriacea Mart. (HEAC) leaves against the toxicity of mercury chloride. MATERIALS AND METHODS: The characterization of components was carried out using high-performance liquid chromatography (HPLC). The minimum inhibitory concentration (MIC) was determined by microdilution method in broth with strains of Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. For evaluation of the modulatory and cytoprotective activity of aminoglycoside antibiotics (gentamicin and amikacin) and mercury chloride (HgCl2), the substances were associated with the HEAC at subinhibitory concentrations (MIC/8). RESULTS AND DISCUSSION: The HPLC analysis revealed the presence of flavonoids such as Luteolin (1.84%) and Quercetin (1.19%) in elevated concentrations. The HEAC presented an MIC >=512 MUg/mL and significant antagonistic action in aminoglycosides modulation, and it also showed cytoprotective activity to S. aureus (significance P < 0.0001) and E. coli (significance P < 0.05) bacteria against the mercury chloride heavy metal with significance, this action being attributed to the chelating properties of the flavonoids found in the chemical identification. CONCLUSIONS: The results acquired in this study show that the HEAC presents cytoprotective activity over the tested strains in vitro and can also present antagonistic effect when associated with aminoglycosides, reinforcing the necessity of taking caution when combining natural and pharmaceutical products. SUMMARY: The hydroalcoholic extract of A. coriacea Mart. presents in vitro cytoprotective activity against the toxic effect of Hg.

AB - BACKGROUND: Popularly known as "jatoba," Hymenaea martiana Hayne is a medicinal plant widely used in the Brazilian Northeast for the treatment of various diseases. OBJECTIVE: The aim of this study was to evaluate the influence of different extractive methods in the production of phenolic compounds from different parts of H. martiana. MATERIALS AND METHODS: The leaves, bark, fruits, and seeds were dried, pulverized, and submitted to maceration, ultrasound, and percolation extractive methods, which were evaluated for yield, visual aspects, qualitative phytochemical screening, phenolic compound content, and total flavonoids. RESULTS: The highest results of yield were obtained from the maceration of the leaves, which may be related to the contact time between the plant drug and solvent. The visual aspects of the extracts presented some differences between the extractive methods. The phytochemical screening showed consistent data with other studies of the genus. Both the vegetal part as the different extractive methods influenced significantly the levels of phenolic compounds, and the highest content was found in the maceration of the barks, even more than the content found previously. No differences between the levels of total flavonoids were significant. The highest concentration of total flavonoids was found in the ultrasound of the barks, followed by maceration on this drug. According to the results, the barks of H. martiana presented the highest total flavonoid contents.

PMID- 27695268 TI - Anti-Advanced Glycation End-product and Free Radical Scavenging Activity of Plants from the Yucatecan Flora. AB - BACKGROUND: Formation and accumulation of advanced glycation end-products (AGE) is recognized as a major pathogenic process in diabetic complications, atherosclerosis and cardiovascular diseases. In addition, reactive oxygen species and free radicals have also been reported to participate in AGE formation and in cell damage. Natural products with antioxidant and antiAGE activity have great therapeutic potential in the treatment of diabetes, hypertension and related complications. Objective: to test ethanolic extracts and aqueous-traditional preparations of plants used to treat diabetes, hypertension and obesity in Yucatecan traditional medicine for their anti-AGE and free radical scavenging activities. MATERIALS AND METHODS: ethanolic extracts of leaves, stems and roots of nine medicinal plants, together with their traditional preparations, were prepared and tested for their anti-AGE and antioxidant activities using the inhibition of advanced glycation end products and DPPH radical scavenging assays, respectively. RESULTS: the root extract of C. fistula (IC50= 0.1 mg/mL) and the leaf extract of P. auritum (IC50= 0.35 mg/mL) presented significant activity against vesperlysine and pentosidine-like AGE. Although none of the aqueous traditional preparations showed significant activity in the anti-AGE assay, both the traditional preparations and the ethanolic extracts of E. tinifolia, M. zapota, O. campechianum and P. auritum showed significant activity in the DPPH reduction assay. CONCLUSIONS: the results suggest that the metabolites responsible for the detected radical-scavenging activity are different to those involved in inhibiting AGE formation; however, the extracts with antioxidant activity may contain other metabolites which are able to prevent AGE formation through a different mechanism. SUMMARY: Ethanolic extracts from nine plants used to treat diabetes, hypertension and obesity in Yucatecan traditional medicine were tested for their anti-AGE and free radical scavenging activities.Significant activity against vesperlysine and pentosidine-like AGE was detected in the root extract of Cassia fistula and the leaf extract of Piper auritum.Traditional preparations and the ethanolic extracts of Ehretia tinifolia, Manilkara zapota, Ocimum campechianum and Piper auritum showed significant activity in the DPPH reduction assay.Results suggest that the metabolites responsible for the detected radical-scavenging activity are different to those involved in inhibiting AGE formation.

PMID- 27695271 TI - Inhibition of Human Cytochrome P450 2c8-catalyzed Amodiaquine N-desethylation: Effect of Five Traditionally and Commonly Used Herbs. AB - BACKGROUND: In Southeast Asia and many parts of the world, herbal products are increasingly used in parallel with modern medicine. OBJECTIVE: This study aimed to investigate the effects of herbs commonly used in Southeast Asia on activity of cytochrome P450 2C8 (CYP2C8), an important human hepatic enzyme in drug metabolism. MATERIALS AND METHODS: The selected herbs, such as Eurycoma longifolia Jack (ELJ), Labisia pumila (LP), Echinacea purpurea (EP), Andrographis paniculata (AP), and Ginkgo biloba (GB), were subjected to inhibition studies using an in vitro CYP2C8 activity marker, amodiaquine N-desethylase assay. Inhibition parameters, inhibitory concentration 50% (IC50), and Ki values were determined to study the potency and mode of inhibition. RESULTS: All herbs inhibited CYP2C8 with the following order of potency: LP > ELJ > GB > AP > EP. LP and ELJ inhibited potently at Ki's of 2 and 4 times the Ki of quercetin, the positive control. The inhibition by LP was uncompetitive in nature as compared to competitive or mixed type inhibition observed with other herbs. GB exhibited moderate inhibitory effect at a Ki6 times larger than quercetin Ki. AP and EP, on the other hand, showed only weak inhibition. CONCLUSION: The herbs we chose represented the more commonly used herbs in Southeast Asia where collision of tradition and modernization in healthcare, if not properly managed, may lead to therapeutic misadventures. We conclude that concurrent consumption of some herbs, in particular, LP and ELJ, may have relevance in drug-herb interactions via CYP2C8 inhibition in vivo. SUMMARY: Herbs are increasingly used in parallel with modern medicines nowadays. In this study five commonly used herbs in Southeast Asia region, ELJ, LP, EP, AP and GB, were investigated for their in vitro inhibitory potency on CYP2C8, an important drug-metaboliz-ing human hepatic enzyme. All herbs inhibited CYP2C8 activity marker, amodiaquine N-desethylation, with potency order of LP > ELJ > GB >AP > EP. LP, ELJ and GB exhibited Ki values of 2, 4 and 6 times the Ki of quercetin, the positive control, indicating potent to moderate degree of enzyme inhibition. AP and EP, on the other hand, showed only weak inhibition. In summary, concurrent consumption of some herbs especially LP and ELJ may have relevance in drug-herb interactions via CYP2C8 inhibition in vivo.

Primarily known for its hepatoprotective actions, silymarin may also stimulate epithelialization and reduce inflammation in excision wound. Previous studies show antioxidant, anti-inflammatory, and antimicrobial actions of silibinin. However, wound healing property of silibinin is not well studied. OBJECTIVE: This study investigates wound healing activity of silibinin topical formulation. MATERIALS AND METHODS: Wound healing activity of 0.2% silibinin gel was assessed by incision and excision wound models in mice. Animals were divided into gel base, silibinin gel, and Mega Heal gel(r) treated groups with six animals in each group. Wound contraction, wound tissue tensile strength, and hydroxyproline content were measured, and histopathological evaluation of wound tissue of all the above treatment groups was carried out. RESULTS: Application of 0.2% silibinin hydrogel for 8 days led to 56.3% wound contraction compared to 64.6% using standard Mega Heal gel with a subsequent increase in hydroxyproline content, which was significantly higher (P < 0.001) over control animals showing 33.2% contraction. After 14 days, percentage of contraction reached 96.1%, 97.6%, and 86.7%, respectively. Wound tissue tensile strength with silibinin (223.55 +/- 3.82 g) and standard (241.38 +/- 2.49 g) was significantly higher (P < 0.001) than control (174.06 +/- 5.75 g). Histopathology of silibinin and standard gel treated wound tissue showed more fibroblasts, fewer macrophage infiltration, and well-formed collagen fibers. CONCLUSION: Here, we show potent wound healing activity of silibinin hydrogel formulation. SUMMARY: 0.2% silibinin hydrogel showed potent wound healing activity in incision and excision wound models in mice. Abbreviations Used: ROS: Reactive oxygen species.

AB - AIM: Abrus precatorius leaves methanolic extract (APME) was evaluated for in vivo antihyperglycemic activity and in vitro insulinotropic effect. MATERIALS AND METHODS: In vivo antihyperglycemic and insulin secretagogue activities were assessed in streptozotocin-induced diabetic rats by oral administration of APME (200 mg/kg body weight [bw]) for 28 days. In vitro insulin secretion mechanisms were studied using mouse insulinoma beta cells (MIN6-beta). In vivo body weight and blood glucose and in vivo and in vitro insulin levels were estimated. RESULTS: In diabetic rats, APME treatment significantly restored body weight (26.39%), blood glucose (32.39%), and insulin levels (73.95%) in comparison to diabetic control rats. In MIN6-beta cells, APME potentiated insulin secretion in a dependent manner of glucose (3-16.7 mM) and extract (5-500 MUg/mL) concentration. Insulin secretagogue effect was demonstrated in the presence of 3 isobutyl-1-methyl xanthine, glibenclamide, elevated extracellular calcium, and K+ depolarized media. Insulin release was reduced in the presence of nifedipine, ethylene glycol tetra acetic acid (calcium blocking agents), and diazoxide (potassium channel opener). CONCLUSION: The study suggests that APME antihyperglycemic activity might involve the insulin secretagogue effect by pancreatic beta cells physiological pathways via K+-ATP channel dependent and independently, along with an effect on Ca2+ channels.

PMID- 27695274 TI - Effects of Curcuma xanthorrhiza Extracts and Their Constituents on Phase II Drug metabolizing Enzymes Activity. AB - BACKGROUND: Curcuma xanthorrhiza is a native Indonesian plant and traditionally utilized for a range of illness including liver damage, hypertension, diabetes, and cancer. OBJECTIVE: The study determined the effects of C. xanthorrhiza extracts (ethanol and aqueous) and their constituents (curcumene and xanthorrhizol) on UDP-glucuronosyltransferase (UGT) and glutathione transferase (GST) activities. MATERIALS AND METHODS: The inhibition studies were evaluated both in rat liver microsomes and in human recombinant UGT1A1 and UGT2B7 enzymes. p-nitrophenol and beetle luciferin were used as the probe substrates for UGT assay while 1-chloro-2,4-dinitrobenzene as the probe for GST assay. The concentrations of extracts studied ranged from 0.1 to 1000 MUg/mL while for constituents ranged from 0.01 to 500 MUM. RESULTS: In rat liver microsomes, UGT activity was inhibited by the ethanol extract (IC50 =279.74 +/- 16.33 MUg/mL). Both UGT1A1 and UGT2B7 were inhibited by the ethanol and aqueous extracts with IC50 values ranging between 9.59-22.76 MUg/mL and 110.71-526.65 MUg/Ml, respectively. Rat liver GST and human GST Pi-1 were inhibited by ethanol and aqueous extracts, respectively (IC50 =255.00 +/- 13.06 MUg/mL and 580.80 +/- 18.56 MUg/mL). Xanthorrhizol was the better inhibitor of UGT1A1 (IC50 11.30 +/- 0.27 MUM) as compared to UGT2B7 while curcumene did not show any inhibition. For GST, both constituents did not show any inhibition. CONCLUSION: These findings suggest that C. xanthorrhiza have the potential to cause herb-drug interaction with drugs that are primarily metabolized by UGT and GST enzymes. SUMMARY: Findings from this study would suggest which of Curcuma xanthorrhiza extracts and constituents that would have potential interactions with drugs which are highly metabolized by UGT and GST enzymes. Further clinical studies can then be designed if needed to evaluate the in vivo pharmacokinetic relevance of these interactions Abbreviations Used: BSA: Bovine serum albumin, CAM: Complementary and alternative medicine, cDNA: Complementary deoxyribonucleic acid, CDNB: 1-Chloro-2,4 dinitrobenzene, CuSO4.5H2O: Copper(II) sulfate pentahydrate, CXEE: Curcuma xanthorrhiza ethanol extract, CXAE: Curcuma xanthorrhiza aqueous extract, GC-MS: Gas chromatography-mass spectroscopy, GSH: Glutathione, GST: Glutathione S transferase, KCl: Potassium chloride, min: Minutes, MgCl2: Magnesium chloride, mg/mL: Concentration (weight of test substance in milligrams per volume of test concentration), mM: Milimolar, Na2CO3: Sodium carbonate, NaOH: Sodium hydroxide, nmol: nanomol, NSAIDs: Non-steroidal antiinflammatory drug, p-NP: para nitrophenol, RLU: Relative light unit, SEM: Standard error of mean, UDPGA: UDP glucuronic acid, UGT: UDP-glucuronosyltransferase. PMID- 27695275 TI - Implementing the Five-A Model of Technical Refinement: Key Roles of the Sport Psychologist. AB - There is increasing evidence for the significant contribution provided by sport psychologists within applied coaching environments. However, this rarely considers their skills/knowledge being applied when refining athletes' already learned and well-established motor skills. Therefore, this article focuses on how a sport psychologist might assist a coach and athlete to implement long-term permanent and pressure proof refinements. It highlights key contributions at each stage of the Five-A model-designed to deliver these important outcomes-providing both psychomotor and psychosocial input to the support delivery. By employing these recommendations, sport psychologists can make multiple positive contributions to completion of this challenging task. PMID- 27695276 TI - Structure of the male copulatory apparatus in Prognathorhynchus busheki (Platyhelminthes, Kalyptorhynchia). AB - Gnathorhynchidae is a diverse taxon of predatory eukalyptorhynch flatworms characterized by an armed proboscis. Their present taxonomy is not concordant with what we know of their phylogeny. Further progress in this area is hindered by a lack of information concerning their morphology. As recent studies have shown, a historical reliance on live observations for species descriptions has resulted in a number of errors and omissions. Here, we redescribe the anatomy of the male copulatory organ of Prognathorhynchus busheki using transmission electron and confocal microscopy, correcting several errors in the original description. Furthermore, we use these results to update our understanding of the anatomy and evolution of male copulatory organs in Gnathorhynchidae and in Platyhelminthes more generally. PMID- 27695277 TI - The origins of Western mind-body exercise methods. AB - Background: Over recent decades, mind-body exercise methods have gained international popularity and importance in the management of musculoskeletal disorders. Objectives: The scope of this paper was to investigate: the origins of Western mind-body methods, their philosophies, exercises, and relationship with mainstream healthcare over the last two centuries. Major findings: Within a few decades of the turn of the 20th century, a cluster of mind-body exercise methods emerged from at least six pioneering founders: Checkley, Muller, Alexander, Randell, Pilates, and Morris. Each was based upon a similar exercise philosophy and similar functional movement-harmonizing exercises. This renaissance of independent mind-body schools occurred in parallel with the demise of the 18th and 19th century gymnasium Physical Culture movement and the concurrent emergence of bodybuilding and strength training. Even though mostly forgotten today, Western mind-body exercise methods enjoyed celebrated success during the first half of the 20th century, were hailed by medical and allied health practitioners and practiced by millions from society's elite to deprived minorities. Conclusions: Rediscovering the Western mind-body exercise movement is hoped to facilitate official healthcare establishment recognition of this kind of training as an integral entity. This may widen research opportunities and consolidate approaches toward: optimal musculoskeletal rehabilitation and injury prevention, promotion of a healthy active lifestyle environment in the modern world, and enhancement of the natural pain-free human athletic look, feel, and performance. PMID- 27695278 TI - Vitamin D Deficiency in Egyptian Systemic Lupus Erythematosus Patients: How Prevalent and Does It Impact Disease Activity? AB - BACKGROUND: The emerging role of vitamin D in immunology and autoimmune disorders has been a worldwide interest in the last decade. Systemic lupus erythematosus (SLE) patients are particularly at a delicate position predisposing them to suffer from vitamin D deficiency due to the multiple risk factors accompanying the disease. Whether vitamin D deficiency is also involved as a risk factor for developing SLE and affecting its course is a considerable concern. OBJECTIVES: The objective of this study was to estimate the prevalence of vitamin D deficiency in SLE patients and its relation to disease. MATERIALS AND METHODS: In our observational cross-sectional study, serum levels of vitamin D [25(OH)D] in 60 SLE patients and 30 age- and sex-matched healthy controls were assessed and estimated for deficiency and insufficiency at 10 and 30 ng/mL, respectively. Disease activity was evaluated by SLE disease activity index (SLEDAI), irreversible organ damage by Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI), and severity by Severity of Disease Index. Fatigue was measured by visual analog scale. RESULTS: Significantly lower levels of 25(OH)D were found in SLE patients (17.6 +/- 6.9 ng/mL) in comparison to controls (79.0 +/- 28.7 ng/mL), with a statistically high significant difference (t = -11.2, P < 0.001). High prevalence of vitamin D insufficiency and deficiency was detected as 73.3% and 23.3%, respectively. Vitamin D had a highly significant negative correlation with SLEDAI (r = -0.495, P < 0.001), SLICC (r = -0.431, P < 0.05), and fatigue (r = -0.436, P < 0.05). CONCLUSION: Vitamin D deficiency and insufficiency were found to be prevalent in SLE patients in our study and related to disease activity and fatigue. If needed, routine screening and consequent repletion of vitamin D are recommended in SLE patients. Restoring adequate vitamin D levels in SLE patients should be more explored as a potential yet simple measure to their usual management to improve their condition. PMID- 27695279 TI - Acute vision loss and choroidal filling delay in the absence of giant-cell arteritis. AB - Giant-cell arteritis (GCA) is a visually devastating disease that often progresses to severe bilateral vision loss if untreated. Diagnosis of GCA is made challenging by the protean nature of the disease and the lack of a simple test that is both highly sensitive and specific. Choroidal filling delay on fluorescein angiography (FA) has been touted as a highly characteristic feature of GCA-related vision loss, although knowledge of both the sensitivity and specificity of this finding remains unproven. We report our experience of delayed choroidal filling on FA in a series of seven patients referred to an academic neuro-ophthalmology practice due to concern for GCA. Despite the FA findings, our examination, diagnostic testing, and long-term follow-up excluded the diagnosis of GCA in all cases, suggesting that choroidal perfusion abnormalities may occur in the absence of GCA. When evaluating a patient for acute vision loss, the astute clinician must remain cognizant of the limitations of FA in the diagnosis of GCA. PMID- 27695280 TI - Clinical evaluation of a trabecular microbypass stent with phacoemulsification in patients with open-angle glaucoma and cataract. AB - PURPOSE: To evaluate the safety and efficacy of the iStent trabecular microbypass stent in combination with cataract surgery in patients with open-angle glaucoma (OAG). METHODS: Retrospective, consecutive case series from October 2012 to December 2015 with no exclusion criteria. The series comprised of 350 eyes with OAG and cataract. Data were collected both preoperatively and postoperatively at day 1 week 1, months 1, 3, 6, 12, 18, and 24. Data included intraocular pressure (IOP), number of glaucoma medications, visual acuity, the incidence of postoperative IOP pressure spikes of greater than >=15 mmHg at any time point, and need for additional surgery. RESULTS: The mean preoperative IOP was 19.13+/ 6.34 mmHg. At 2 years postoperation, mean IOP was 15.17+/-3.53 mmHg (P<0.0001). The mean number of glaucoma medications was 1.19+/-1.00 preoperatively and 0.61+/ 0.96 (P<0.0001) at 2 years postoperation. At 1 day postoperatively, 31 eyes (12.4%) experienced an IOP increase of 15 mmHg above their baseline IOP that responded to topical therapy. Two patients required additional tube shunt surgery. CONCLUSION: The insertion of the iStent trabecular microbypass stent in combination with cataract surgery effectively lowers IOP in OAG patients. The magnitude of IOP reduction was more significant in patients with higher preoperative pressure. Medication use was also significantly reduced postoperatively. The safety profile appears favorable with a low rate of IOP spikes and only two eyes (<1%) requiring additional surgery.

PMID- 27695282 TI - Cosmetic and functional outcomes of frontalis suspension surgery using autologous fascia lata or silicone rods in pediatric congenital ptosis. AB - PURPOSE: Cosmetic and functional outcomes of frontalis suspension surgery using autologous fascia lata (FL) or silicone rods (SRs) in pediatric congenital ptosis. DESIGN: Retrospective case series. STUDY SUBJECTS: Patients with congenital ptosis, aged 18 years or younger, during the period under study (2005 2011) at the Singapore National Eye Centre. METHODS: Review of case records for functional and cosmetic outcome measures after frontalis suspension surgery using either SRs or autologous FL. RESULTS: A total of 18 patients were studied (14 eyelids had FL, 16 eyelids had SRs) with mean ages of 7.1 (range 5-12) and 7.2 (range 4-18) years for the FL and SR groups, respectively. Mean follow-up period was 41.6 (range 11.2-77.9) and 48.6 (16.1-87.4) months, respectively. Patients in the FL group had better functional and cosmetic results compared to those in silicone group, with no recurrence of ptosis. More complications were experienced by patients in the SR group. CONCLUSION: Autologous FL for frontalis suspension remains an excellent choice for (and should be considered as useful surgical armamentarium for) repair of severe congenital ptosis. PMID- 27695283 TI - Agreement of noninvasive tear break-up time measurement between Tomey RT-7000 Auto Refractor-Keratometer and Oculus Keratograph 5M. AB - BACKGROUND: It is difficult to standardize assessment of dry eye in different clinical settings. Increasingly, tear stability is recognized to be important for the definition and assessment of patients with dry eye. Recently, two commercially available instruments have been made available for objectively measuring noninvasive tear break-up time (NIBUT), as an indicator of tear stability: the Tomey RT-7000 Auto Refractor-Keratometer and Oculus Keratograph (K)5M. We aim to assess the agreement of NIBUT measurements using these modalities. METHODS: This prospective cross-sectional study was carried out in a tertiary referral eye center and involved 126 consecutive dry eye patients. NIBUT assessment was performed on the right eyes of participants with both the RT-7000 and the K5M techniques, with the order of assessment randomized. The Standardized Patient Evaluation of Eye Dryness (SPEED) questionnaires were administered to assess dry eye symptoms in the 2 weeks before assessment. RESULTS: The age of the participants was 56.0+/-14.3 years (69.84% females). Measurements for both modalities were non-normally distributed (right-skewed). The median RT-7000 and K5M readings were 4.2 (range 0.1-10.0) and 6.4 (0.1-24.9) seconds, respectively. RT-7000 and K5M readings were poorly correlated (rho=0.061, P=0.495). Intraclass correlation coefficient between the modalities was 0.187 (95% confidence interval -0.097 to 0.406). The Bland-Altman plot showed no systematic differences between the readings with these machines. The agreement between machines was not different in different SPEED categories. CONCLUSION: While there are theoretical and practical benefits of NIBUT for assessment of tear stability over dye-based methods, the agreement between the two modalities was poor. Hence, studies and trials assessing NIBUT should avoid using these modalities interchangeably for NIBUT assessment. More research is needed to improve consensus on how to determine NIBUT. PMID- 27695284 TI - Noninvasive detection of microaneurysms in diabetic retinopathy by swept-source optical coherence tomography. AB - BACKGROUND AND OBJECTIVES: A method of identifying retinal vascular microaneurysms (MAs) in nonproliferative diabetic retinopathy (NPDR) using swept source optical coherence tomography (SS-OCT). PATIENTS AND METHODS: SS-OCT images were acquired in 17 eyes with NPDR using prototype SS-OCT device and fluorescein angiography (FA) images were obtained simultaneously. MAs identified on SS-OCT slabs were correlated to MAs identified on FA. RESULTS: MAs were identified in SS OCT slabs in 15/17 eyes, resulting in NPDR diagnosis rate of 88%. Mean number of MAs identified on FA was 11.7+/-11.9 (total 199) and was 8.1+/-9.3 (total 137) on SS-OCT. Wilcoxon rank sum test showed no significant difference in MAs detected on SS-OCT and FA (P=0.2995) across eyes. Wilcoxon rank sum test showed SS-OCT detected slightly fewer MAs than FA per eye (3.65 less, P=0.0009). CONCLUSION: SS OCT visualization of MAs could serve as a tool for diagnosing NPDR, and possibly applied as an imaging biomarker for population-based diabetic retinopathy screening. PMID- 27695285 TI - The association of hematologic inflammatory markers with atherogenic index in type 2 diabetic retinopathy patients. AB - BACKGROUND: Atherogenic dyslipidemia is particularly common in people with type 2 diabetes (DM2). Platelets from patients with DM2 have increased reactivity and baseline activation. The aim of the present study is to evaluate the relationship between atherogenic index and hematologic inflammatory markers and to evaluate the relationship between these parameters and associated variables in diabetic retinopathy (DR) patients. METHODS: The medical records of all patients admitted to the eye clinic between January and December 2014 were evaluated systematically. Laboratory parameters of 278 outpatients with DM2 diagnosed after the age of 30 years and 107 healthy subjects were analyzed. RESULTS: The DM2 + DR group consisted of 120 patients (47 males and 73 females; mean age 59.8+/-9.2 years). The DM2 without DR group consisted of 158 patients (59 males and 99 females; mean age 57.3+/-12.2 years). Mean platelet volume, platelet distribution width (PDW), platelet-lymphocyte (P/L) ratio, triglycerides, and atherogenic index were higher in DM2 patients than in control patients, but there was no difference between the DM2 + DR and the DM2 without DR groups. Only P/L ratio was different in the DM2 + DR patients compared to the DM2 without DR patients. Hemoglobin A1c levels correlated very weakly with the mean platelet volume, PDW, P/L ratio, and the red cell distribution width. The atherogenic index was very weakly correlated with the P/L ratio, PDW, and red cell distribution width. CONCLUSION: Dyslipidemia-induced inflammation contributes to pathological processes that lead to retinopathy in DR patients. PMID- 27695286 TI - Corneal stromal demarcation line after collagen cross-linking in corneal ectatic diseases: a review of the literature. AB - Collagen cross-linking (CXL) is a relatively new conservative approach for progressive corneal ectasia, which is able to strengthen corneal tissue reforming new covalent bonds. Subjective and objective results following this method seem to be promising. In recent years, newer CXL protocols have been developed to perform more effective and less invasive procedures. The increasing diffusion of CXL in the corneal ectatic disease has increased the need to have actual indices regarding the efficacy of the treatment. Evaluation of demarcation line (DL), a transition zone between the cross-linked anterior corneal stroma and the untreated posterior corneal stroma, is considered a measurement of the depth of CXL treatment into the stroma. Some evidence in the literature emphasize that DL could be a measure of effectiveness of the CXL. On the contrary, some authors believe that the "the deeper, the better" principle is rather a simplistic approach for interpreting the clinical importance of the corneal stromal DL. PMID- 27695287 TI - Longevity results of modified Hughes procedure in reconstructing large lower eyelid defects. AB - PURPOSE: The purpose of this study was to evaluate the longevity results of modified Hughes procedure in reconstructing large lower eyelid defects. BACKGROUND: The modified Hughes procedure was used to reconstruct large full thickness lower eyelid defects. Meanwhile, the functional results indicated that ocular surface health in the treated eyes may be affected. PATIENTS AND METHODS: Noncomparative, case series retrospective study was designed after obtaining the approval of the institutional review board at the Ophthalmology Department, Menoufia University, Egypt, where the results of cases who underwent surgery with the modified Hughes procedure during a 7-year interval were evaluated. RESULTS: Eleven patients (seven males and four females) in the age range 59-77 years (mean age 67+/-5 years) were identified. The follow-up ranged from 12 months to 48 months. Cosmetic, functional, and postoperative results were analyzed. CONCLUSION: Despite the favorable cosmetic results of the Hughes tarsoconjunctival flap, the procedure has its own limitations. The results indicated that it does affect the functions and tear film stability in the treated eyes. PMID- 27695288 TI - Eltrombopag for the treatment of aplastic anemia: current perspectives. AB - Aplastic anemia (AA) is a potential life-threatening hematopoietic stem cell (HSC) disorder resulting in cytopenia. The mainstays of treatment for AA are definitive therapy to restore HSCs and supportive measures to ameliorate cytopenia-related complications. The standard definitive therapy is HSC transplantation for young and medically fit patients with suitable donors and immunosuppressive therapy (IST) with antithymocyte globulin and cyclosporine for the remaining patients. A significant proportion of patients are refractory to IST or relapse after IST. Various strategies have been explored in these patients, including second course of antithymocyte globulin, high-dose cyclophosphamide, and alemtuzumab. Eltrombopag, a thrombopoietin mimetic, has recently emerged as an encouraging and promising agent for patients with refractory AA. It has demonstrated efficacy in restoring trilineage hematopoiesis, and this positive effect continues after discontinuation of the drug. There are ongoing clinical trials exploring the role of eltrombopag as a first-line therapy in moderate to severe AA and a combination of eltrombopag with IST in severe AA. PMID- 27695290 TI - Protein kinase C-mediated sodium glucose transporter 1 activation in precondition induced cardioprotection. AB - The concept of cardioprotection through preconditioning against ischemia reperfusion (I/R) injury is well known and established. However, among different proposed mechanisms regarding the concept of ischemic preconditioning, protein kinase C (PKC)-mediated cardioprotection through ischemic preconditioning plays a key role in myocardial I/R injury. Thus, this study was designed to find the relationship between PKC and sodium glucose transporter 1 (SGLT1) in preconditioning-induced cardioprotection, which is ill reported till now. By applying a multifaceted approach, we demonstrated that PKC activates SGLT1, which curbed oxidative stress and apoptosis against I/R injury. PKC activation enhances cardiac glucose uptake through SGLT1 and seems essential in preventing I/R induced cardiac injury, indicating a possible cross-talk between PKC and SGLT1. PMID- 27695289 TI - Gender differences in the adverse events' profile registered in seven observational studies of a wide gender-medicine (MetaGeM) project: the MetaGeM safety analysis. AB - BACKGROUND: MetaGeM is a wide gender-medicine project comprising post hoc and meta-analyses by gender of clinical outcomes, therapeutic approaches, and safety data from previously conducted observational studies to explore possible gender differences in real-life clinical settings. We report the results of the safety meta-analysis of seven MetaGeM studies, evaluating gender differences in adverse event (AE) incidence and severity. METHODS: Data were collected between February 2002 and July 2013. Male and female patients were compared for the main safety variables, using Student's t-test, chi2 test, or Fisher's exact test as appropriate. As supportive analysis, a logistic regression model was estimated to evaluate associations between gender and outcome. RESULTS: In total, 4,870 patients (46% females, 54% males) were included in the analysis; age was higher for females (mean +/- standard deviation 61.2+/-18.3 years) than males (56.3+/ 16.6 years). Overall, 264 AEs were reported (59.1% in males). There were no significant gender differences in the percentage of patients with at least one AE: 3.0% for females versus 3.9% for males, chi2 test P>0.05. According to the logistic regression model results, no association between gender and AEs occurrence seems to exist. A statistically significant gender difference in the percentage of drug-related AEs emerged (37.6% in females vs 20.8% in males, chi2P=0.0039). Slightly significantly more AEs in females were addressed with treatment compared with males (78.1% vs 66.7%, chi2P=0.0485). Total serious AEs (SAEs) were 47 (72% in males). The frequency of patients with >=1 SAE was 0.6% in females versus 1.2% in males (chi2 test P=0.0246). CONCLUSION: This safety analysis on a large sample of almost 5,000 patients with different diseases and treated with a wide range of different drugs provides a useful overview on possible gender differences in drug tolerability, which may be helpful in more accurately designing future clinical trials from a gender-specific perspective. PMID- 27695291 TI - Effects of low-carbohydrate diet therapy in overweight subjects with autoimmune thyroiditis: possible synergism with ChREBP. AB - The thyroid is one of the metabolism regulating glands. Its function is to determine the amount of calories that the body has to burn to maintain normal weight. Thyroiditides are inflammatory processes that mainly result in autoimmune diseases. We have conducted the present study in order to have a clear picture of both autoimmune status and the control of body weight. We have evaluated the amount of either thyroid hormones, or antithyroid, or anti-microsomal, or anti peroxidase antibodies (Abs) in patients with high amounts of Abs. In a diet devoid of carbohydrates (bread, pasta, fruit, and rice), free from goitrogenic food, and based on body mass index, the distribution of body mass and intracellular and extracellular water conducted for 3 weeks gives the following results: patients treated as above showed a significant reduction of antithyroid (-40%, P<0.013), anti-microsomal (-57%, P<0.003), and anti-peroxidase (-44%, P<0,029) Abs. Untreated patients had a significant increase in antithyroid (+9%, P<0.017) and anti-microsomal (+30%, P<0.028) Abs. Even the level of anti peroxidase Abs increased without reaching statistical significance (+16%, P>0064). With regard to the body parameters measured in patients who followed this diet, reduction in body weight (-5%, P<0.000) and body mass index (-4%, P<0.000) were observed. Since 83% of patients with high levels of autoantibodies are breath test positive to lactase with a lactase deficit higher than 50%, this fact led us to hypothesize a correlation with carbohydrate-responsive element binding protein and therefore a possible role of carbohydrate metabolism in the development and maintenance of autoimmune thyroiditis associated with body weight increase and slower basic metabolism. PMID- 27695292 TI - A triazole derivative elicits autophagic clearance of polyglutamine aggregation in neuronal cells. AB - Trinucleotide CAG repeat expansion in the coding region of genes has a propensity to form polyglutamine (polyQ) aggregates that contribute to neuronal disorders. Strategies in elevating autophagy to disintegrate the insoluble aggregates without injuring cells have become a major goal for therapy. In this work, a triazole derivative, OC-13, was found accelerating autophagic clearance of polyQ aggregation in human neuroblastoma cells following induction of the enhanced green fluorescence-conjugated chimeric protein that enclosed 79 polyQ repeats (Q79-EGFP). OC-13 accelerated autophagy development and removed nuclear Q79-EGFP aggregates. The increase of Beclin-1, turnover of LC3-I to LC3-II and degradation of p62 supported autophagy activation. Pretreatment of autophagy inhibitor, bafilomycin A1, not only suppressed autophagolysome fusion, but also impeded aggregate eradication. The study also showed that c-Jun N-terminal kinase/Beclin 1 pathway was activated during OC-13 treatment and c-Jun N-terminal kinase inhibitor impaired autophagy and final breakdown. Autophagic clearance of the insoluble aggregates demonstrated the feasibility of OC-13 in alleviating neuronal disorders because of expanded glutamine stretches. PMID- 27695295 TI - Validation of a treatment satisfaction questionnaire in non-Hodgkin lymphoma: assessing the change from intravenous to subcutaneous administration of rituximab. AB - BACKGROUND: A subcutaneous (SC) formulation of rituximab (MabThera(r)/Rituxan(r)) has been developed that could reduce administration time and improve patient satisfaction with treatment. The Rituximab Administration Satisfaction Questionnaire (RASQ) was created to assess patients' perceptions and satisfaction with rituximab SC (RASQ-SC) or rituximab intravenous (RASQ-IV). We assessed the content validity and psychometric properties of RASQ in patients with non-Hodgkin lymphoma. METHODS: Face and content validity of RASQ-SC and RASQ-IV were qualitatively assessed using 60-minute combined concept elicitation and cognitive debriefing interviews. Psychometric validation of RASQ (item performance and reliability) was assessed quantitatively against the established Cancer Therapy Satisfaction Questionnaire (CTSQ), using questionnaire data from the PrefMab (NCT01724021) and MabCute (NCT01461928) clinical studies. RESULTS: RASQ-IV demonstrated excellent coverage of concepts relevant to patients' (n=10) own treatment experiences and no new concepts were identified. Patients' expectations of rituximab SC were conceptually consistent with items included in the RASQ-SC, suggesting that the tool is also conceptually adequate. In 1,051 patients from PrefMab and MabCute, correlations with domains such as "RASQ: Physical Impacts" and "CTSQ: Feelings About Side Effects", "RASQ: Physical Impacts" and "CTSQ: Satisfaction With Therapy", and "RASQ: Satisfaction" and "CTSQ: Satisfaction With Therapy", achieved moderate-to-high correlations (>0.4) for convergent domains and <0.3 for divergent domains. CONCLUSION: This study supports the qualitative face and content validity and psychometric validity of RASQ-IV and RASQ-SC. Minor revisions were made to the questionnaires to enhance clarity and aid consistent reporting. PMID- 27695293 TI - Application of physiologically based pharmacokinetic modeling in predicting drug drug interactions for sarpogrelate hydrochloride in humans. AB - BACKGROUND: Evaluating the potential risk of metabolic drug-drug interactions (DDIs) is clinically important. OBJECTIVE: To develop a physiologically based pharmacokinetic (PBPK) model for sarpogrelate hydrochloride and its active metabolite, (R,S)-1-{2-[2-(3-methoxyphenyl)ethyl]-phenoxy}-3-(dimethylamino)-2 propanol (M-1), in order to predict DDIs between sarpogrelate and the clinically relevant cytochrome P450 (CYP) 2D6 substrates, metoprolol, desipramine, dextromethorphan, imipramine, and tolterodine. METHODS: The PBPK model was developed, incorporating the physicochemical and pharmacokinetic properties of sarpogrelate hydrochloride, and M-1 based on the findings from in vitro and in vivo studies. Subsequently, the model was verified by comparing the predicted concentration-time profiles and pharmacokinetic parameters of sarpogrelate and M 1 to the observed clinical data. Finally, the verified model was used to simulate clinical DDIs between sarpogrelate hydrochloride and sensitive CYP2D6 substrates. The predictive performance of the model was assessed by comparing predicted results to observed data after coadministering sarpogrelate hydrochloride and metoprolol. RESULTS: The developed PBPK model accurately predicted sarpogrelate and M-1 plasma concentration profiles after single or multiple doses of sarpogrelate hydrochloride. The simulated ratios of area under the curve and maximum plasma concentration of metoprolol in the presence of sarpogrelate hydrochloride to baseline were in good agreement with the observed ratios. The predicted fold-increases in the area under the curve ratios of metoprolol, desipramine, imipramine, dextromethorphan, and tolterodine following single and multiple sarpogrelate hydrochloride oral doses were within the range of >=1.25, but <2-fold, indicating that sarpogrelate hydrochloride is a weak inhibitor of CYP2D6 in vivo. Collectively, the predicted low DDIs suggest that sarpogrelate hydrochloride has limited potential for causing significant DDIs associated with CYP2D6 inhibition. CONCLUSION: This study demonstrated the feasibility of applying the PBPK approach to predicting the DDI potential between sarpogrelate hydrochloride and drugs metabolized by CYP2D6. Therefore, it would be beneficial in designing and optimizing clinical DDI studies using sarpogrelate as an in vivo CYP2D6 inhibitor. PMID- 27695294 TI - Combined computational and experimental studies of molecular interactions of albuterol sulfate with bovine serum albumin for pulmonary drug nanoparticles. AB - Albumin-based nanoparticles (NPs) are a promising technology for developing drug carrier systems, with improved deposition and retention profiles in lungs. Improved understanding of these drug-carrier interactions could lead to better drug-delivery systems. The present study combines computational and experimental methods to gain insights into the mechanism of binding of albuterol sulfate (AS) to bovine serum albumin (BSA) on the molecular level. Molecular dynamics simulation and surface plasmon resonance spectroscopy were used to determine that there are two binding sites on BSA for AS: the first of which is a high-affinity site corresponding to AS1 and the second of which appears to represent the integrated functions of several low-affinity sites corresponding to AS2, AS3, and AS8. AS1 was the strongest binding site, established via electrostatic interaction with Glu243 and Asp255 residues in a hydrophobic pocket. Hydrogen bonds and salt bridges played a main role in the critical binding of AS1 to BSA, and water bridges served a supporting role. Based upon the interaction mechanism, BSA NPs loaded with AS were prepared, and their drug-loading efficiency, morphology, and -release profiles were evaluated. Successful clinical development of AS-BSA-NPs may improve therapy and prevention of bronchospasm in patients with reversible obstructive airway disease, and thus provide a solid basis for expanding the role of NPs in the design of new drug-delivery systems. PMID- 27695296 TI - Nepalese patients' perceptions of treatment modalities for type 2 diabetes. AB - BACKGROUND: Perceptions and beliefs about treatment can influence patients' adherence to treatment regimens. Perceptions, in turn, are often shaped by patients' sociocultural context. Nepal and the Nepalese have unique sociocultural traditions and beliefs, and their perceptions of diabetes treatment remain largely unexplored. This study explored Nepalese participants' perceptions of diabetes treatment, and whether perceptions differed between the Nepalese living in Australia and Nepal. METHODS: Face-to-face qualitative interviews (n=48) were conducted with Nepalese participants with type 2 diabetes in Sydney and Kathmandu. All interviews were audio-recorded, transcribed verbatim, and thematically analyzed. RESULTS: Perceptions of diabetes treatment were similar among Nepalese participants in Australia and Nepal. There was a general reluctance to start oral antidiabetic medications and an even greater reluctance to commence parenteral (insulin) therapy. Participants preferred to try lifestyle modifications and alternative treatments such as herbs and "traditional" medicines, particularly as a first step. Unwillingness to take medications was primarily associated with the belief that, once started, these medications needed to be taken for life, and perceptions of long-term harms caused by such medications. Even when commenced on medication, participants were averse to any type of therapy escalation, for example, moving to insulin therapy. Insulin was perceived as the "last option" available for diabetes treatment. Most participants, however, did not find medication taking challenging once they had commenced treatment. CONCLUSION: Antidiabetic medications were perceived to be harmful and unstoppable once initiated. These perceptions significantly impacted participants' willingness to commence antidiabetic medications and therefore have the potential to adversely affect their medication-taking behavior. This study therefore highlights the need to explore the impact of these perceptions on participants' medication-taking behavior, and the need to address patients' views of "modern" (commonly prescribed) and "traditional" (natural) medications through information and education, to ensure increased understanding of how medications are used for diabetes management. PMID- 27695297 TI - Self-perception of knowledge and adherence reflecting the effectiveness of antiretroviral therapy. AB - OBJECTIVES: To evaluate which indirect method for assessing adherence best reflects highly active antiretroviral therapy (HAART) effectiveness and the factors related to adherence. METHOD: This descriptive, cross-sectional study was performed in 2012 at a reference center of the state of Sao Paulo. Self-report (simplified medication adherence questionnaire [SMAQ]) and drug refill parameters were compared to the viral load (clinical parameter of the effectiveness of pharmacotherapy [EP]) to evaluate the EP. The "Cuestionario para la Evaluacion de la Adhesion al Tratamiento Antiretroviral" (CEAT-VIH) was used to evaluate factors related to adherence and the EP and, complementarily, patient self perception of adherence was compared to the clinical parameter of the EP. RESULTS: Seventy-five patients were interviewed, 60 of whom were considered as adherent from the clinical parameter of the EP and ten were considered as adherent from all parameters. Patient self-perception about adherence was the instrument that best reflected the EP when compared to the standardized self report questionnaire (SMAQ) and drug refill parameter. The level of education and the level of knowledge on HAART were positively correlated to the EP. Forgetfulness, alcohol use, and lack of knowledge about the medications were the factors most frequently reported as a cause of nonadherence. CONCLUSION: A new parameter of patient self-perception of adherence, which is a noninvasive, inexpensive instrument, could be applied and assessed as easily as self-report (SMAQ) during monthly drug refill, since it allows monitoring adherence through pharmaceutical assistance. Therefore, patient adherence to HAART could be evaluated using self-perception (CEAT-VIH) and the viral load test. PMID- 27695299 TI - Medication adherence in patients with diabetes mellitus: does physician drug dispensing enhance quality of care? Evidence from a large health claims database in Switzerland. AB - BACKGROUND: The drug-dispensing channel is a scarcely explored determinant of medication adherence, which is considered as a key indicator for the quality of care among patients with diabetes mellitus. In this study, we investigated the difference in adherence between diabetes patients who obtained their medication directly from a prescribing physician (physician dispensing [PD]) or via a pharmacy. METHODS: A retrospective cohort study was conducted using a large health care claims database from 2011 to 2014. Patients with diabetes of all ages and receiving at least one oral antidiabetic drug (OAD) prescription were included. We calculated patients' individual adherence to OADs defined as the proportion of days covered (PDC), which was measured over 1 year after patient identification. Good adherence was defined as PDC >=80%. Multivariate logistic regression analysis was performed to assess the relationship between the PDC and the dispensing channel (PD, pharmacy). RESULTS: We identified a total of 10,430 patients prescribed drugs by a dispensing physician and 16,292 patients receiving drugs from a pharmacy. Medication adherence was poor in both patient groups: ~40% of the study population attained good adherence to OADs. We found no significant impact of PD on the adherence level in diabetes patients. Covariates associated significantly with good adherence were older age groups, male sex, occurrence of comorbidity and combined diabetes drug therapy. CONCLUSION: In conclusion, adherence to antihyperglycemic medication is suboptimal among patients with diabetes. The results of this study provide evidence that the dispensing channel does not have an impact on adherence in Switzerland. Certainly, medication adherence needs to be improved in both supply settings. Physicians as well as pharmacists are encouraged to develop and implement useful tools to increase patients' adherence behavior. PMID- 27695298 TI - Patient considerations in cataract surgery - the role of combined therapy using phenylephrine and ketorolac. AB - Cataract, a degradation of the optical quality of the crystalline lens, progressive and age-related, is the leading cause of treatable blindness worldwide. Cataract surgery is the most common surgical procedure performed by ophthalmologists and is the only effective treatment for cataracts. Advances in the surgical techniques and better postoperative visual outcomes have progressively changed the primary concern of cataract surgery to become a procedure refined to yield the best possible refractive results. Sufficient mydriasis during cataract removal is critical to a successful surgical outcome. Poor pupil dilation can lead to serious sight-threatening complications that significantly increase the cost of surgery and decrease patients comfort. Mydriasis is obtained using anticholinergic and sympathomimetic drugs. Phenylephrine, an alpha1-adrenergic receptor agonist, can efficiently dilate the pupil when administered by intracameral injection. Additionally, nonsteroidal anti-inflammatory drugs (NSAIDs) like ketorolac, which inhibit the synthesis of prostaglandins, are used to decrease intraoperative miosis, control pain and inflammation associated with cataract surgery, and to prevent the development of cystoid macular edema following surgery. Recently, a new combination of phenylephrine and ketorolac (Omidria(r)) has been approved by United States Food and Drug Administration for use during cataract surgery to maintain intraoperative mydriasis, prevent miosis, and reduce postoperative pain and inflammation. Clinical trials have shown that this new combination is effective, combining the positive effects of both drugs with a good safety profile and patient tolerability. Moreover, recent reports suggest that this combination is also effective in patients with high risk of poor pupil dilation. In conclusion, cataract is a global problem that significantly affects patients' quality of life. However, they can be managed with a safe and minimally invasive surgery. Advances in surgical techniques and newer pharmacological agents such as the combination of phenylephrine and ketorolac, together with better intraocular lenses, have greatly improved visual outcomes and thus patients' expectations regarding visual recovery are also increasing. PMID- 27695300 TI - Factors associated with beta-blocker initiation and discontinuation in a population-based cohort of seniors newly diagnosed with heart failure. AB - PURPOSE: beta-Blockers (bisoprolol, carvedilol, and metoprolol) are the cornerstone of heart failure (HF) management. The incidence rate of beta-blocker initiation and discontinuation and their associated factors among seniors with a first HF diagnosis were assessed. METHODS: A population-based inception cohort study that included all individuals aged >=65 years with a first HF diagnosis in Quebec was conducted. beta-Blockers initiation among 91,131 patients who were not using beta-blockers at the time of HF diagnosis and discontinuation among those who initiated a beta-blocker after HF diagnosis were assessed. Stepwise Cox regression analyses were used to calculate hazard ratios (HR) and to identify factors associated with beta-blocker initiation and discontinuation. RESULTS: After HF diagnosis, 32,989 (36.2%) individuals initiated a beta-blocker. Of these, 15,408 (46.7%) discontinued their beta-blocker during the follow-up. Individuals more likely to initiate a beta-blocker were those diagnosed in a recent calendar year (2009: HR, 2.11; 95% confidence interval [CI], 2.00-2.23) and diagnosed by a cardiologist (HR, 1.38; 95% CI, 1.34-1.42). Individuals less likely to initiate were those aged >=90 years (HR, 0.65; 95% CI, 0.61-0.68) and those with chronic obstructive pulmonary disease (HR, 0.66; 95% CI, 0.64-0.68). Individuals more likely to discontinue were those with more than nine medical consultations (HR, 1.14; 95% CI, 1.10-1.18) and those with dementia (HR, 1.13; 95% CI, 1.01-1.27). Individuals less likely to discontinue were those diagnosed in a recent calendar year (2009: HR 0.74; 95% CI, 0.65-0.82) and those exposed to another beta-blocker before HF diagnosis (HR, 0.88; 95% CI, 0.85-0.91). CONCLUSION: Quebec seniors seem to be underexposed to beta-blocker following HF diagnosis. Among those who initiate beta-blocker use, discontinuation is high. Better understanding of the underlying causes is needed to help target interventions to improve the management of HF. PMID- 27695301 TI - Patient-centered care interventions for the management of alcohol use disorders: a systematic review of randomized controlled trials. AB - ISSUES: Patient-centered care (PCC) is increasingly accepted as an integral component of good health care, including addiction medicine. However, its implementation has been controversial in people with alcohol use disorders. APPROACH: A systematic search strategy was devised to find completed randomized controlled trials enrolling adults (>18 years) with alcohol use disorders. Studies had to use a PCC approach such that they should have been individualized, respectful to the patients' own goals, and empowering. Studies until September 2015 were searched using PubMed, Scopus, the Cochrane Library, PsychINFO, and Web of Knowledge. KEY FINDINGS: In total, 40 studies enrolling 16,020 patients met the inclusion criteria. Assessment revealed two main categories of study: psychosocial (n=35 based on motivational interviewing) and pharmacological (n=5 based on an as needed dosing regimen). Psychosocial interventions were further classified according to the presence or absence of an active comparator. When no active comparator was present, studies were classified according to the number of sessions (>=1). Results from single sessions of motivational interviewing showed no clear benefit on alcohol consumption outcomes, with few studies indicating benefit of PCC versus control. Although the results for studies of multiple sessions of counseling were also mixed, many did show a significant benefit of the PCC intervention. By contrast, studies consistently demonstrated a benefit of pharmacologically supported PCC interventions, with most of the differences reaching statistical significance. IMPLICATIONS: PCC-based interventions may be beneficial for reducing alcohol consumption in people with alcohol use disorders. PMID- 27695304 TI - Invasive coronary angiography in patients with acute exacerbated COPD and elevated plasma troponin. AB - BACKGROUND: In acute exacerbation of COPD, increased plasma levels of cardiac troponin are frequent and associated with increased mortality. Thus, we aimed at prospectively determining the diagnostic value of coronary angiography in patients with exacerbated COPD and concomitantly elevated cardiac troponin. PATIENTS AND METHODS: A total of 88 patients (mean age 72.9+/-9.2 years, 56.8% male) hospitalized for acute exacerbation of COPD with elevated plasma troponin were included. All patients underwent coronary angiography within 72 hours after hospitalization. Complementary 12-lead electrocardiogram, transthoracic echocardiography, pulmonary function, and angiological testing were performed. RESULTS: Coronary angiography objectified the presence of ischemic heart disease (IHD) in 59 patients (67.0%), of whom 34 patients (38.6% of total study population) underwent percutaneous coronary intervention. Among these 34 intervened patients, the vast majority (n=26, 76.5%) had no previously known IHD, whereas only eight out of 34 patients (23.5%) presented an IHD history. Patients requiring coronary intervention showed significantly reduced left ventricular ejection fraction (45.8%+/-13.1% vs 55.1%+/-13.3%, P=0.01) and a significantly more frequent electrocardiographic ST-segment depression (20.6% vs 7.4%, P=0.01). Neither additional laboratory parameters for inflammation and myocardial injury nor lung functional measurements differed significantly between the groups. CONCLUSION: Angiographically confirmed IHD that required revascularization occurred in 38.6% of exacerbated COPD patients with elevated cardiac troponin. In this considerable portion of patients, coronary angiography emerged to be of diagnostic and therapeutic value. PMID- 27695303 TI - Geriatric falls in the context of a hospital fall prevention program: delirium, low body mass index, and other risk factors. AB - BACKGROUND: Inpatient geriatric falls are a frequent complication of hospital care that results in significant morbidity and mortality. OBJECTIVE: Evaluate factors associated with falls in geriatric inpatients after implementation of the fall prevention program. METHODS: Prospective observational study comprised of 788 consecutive patients aged 79.5+/-7.6 years ( [Formula: see text] +/- standard deviation) (66% women and 34% men) admitted to the subacute geriatric ward. Comprehensive geriatric assessment (including Mini-Mental State Examination, Barthel Index of Activities of Daily Living, and modified Get-up and Go Test) was performed. Confusion Assessment Method was used for diagnosis of delirium. Patients were categorized into low, moderate, or high fall risk groups after clinical and functional assessment. RESULTS: About 15.9%, 21.1%, and 63.1% of participants were classified into low, moderate, and high fall risk groups, respectively. Twenty-seven falls were recorded in 26 patients. Increased fall probability was associated with age >=76 years (P<0.001), body mass index (BMI) <23.5 (P=0.007), Mini-Mental State Examination <20 (P=0.004), Barthel Index <65 (P=0.002), hemoglobin <7.69 mmol/L (P=0.017), serum protein <70 g/L (P=0.008), albumin <32 g/L (P=0.001), and calcium level <2.27 mmol/L. Four independent factors associated with fall risk were included in the multivariate logistic regression model: delirium (odds ratio [OR] =7.33; 95% confidence interval [95% CI] =2.76-19.49; P<0.001), history of falls (OR =2.55; 95% CI =1.05-6.19; P=0.039), age (OR =1.14; 95% CI =1.05-1.23; P=0.001), and BMI (OR =0.91; 95% CI =0.83-0.99; P=0.034). CONCLUSION: Delirium, history of falls, and advanced age seem to be the primary risk factors for geriatric falls in the context of a hospital fall prevention program. Higher BMI appears to be associated with protection against inpatient geriatric falls. PMID- 27695305 TI - Impact of current cough on health-related quality of life in patients with COPD. AB - BACKGROUND: Cough and sputum production are frequent in chronic obstructive pulmonary disease (COPD). The objective of this study was to examine the relationship between cough and sputum production and health-related quality of life in COPD. METHODS: A cross-sectional study was conducted in the French Initiatives COPD cohort and assessed cough and sputum production within the past 7 days using the cough and sputum assessment questionnaire (CASA-Q), health related quality of life, spirometry, smoking status, dyspnea, exacerbations, anxiety and depression, and comorbidities. RESULTS: One hundred and seventy-eight stable COPD patients were included (age, 62 [56-69] years, 128 male, forced expiratory volume in 1 second [FEV1]: 57 [37-72] % predicted) (median [Q1-Q3]). In univariate analyses, health-related quality of life (Saint George's respiratory questionnaire total score) was associated with each CASA-Q domain and with chronic bronchitis, exacerbations, dyspnea, FEV1, depression, and anxiety. All four domains introduced separately were independently associated with health related quality of life. When introduced together in multivariate analyses, only the cough impact domain remained independently associated with health-related quality of life (R2=0.60). With chronic bronchitis (standard definition) instead of the CASA-Q, the R2 was lower (R2=0.54). CONCLUSION: This study provides evidence that current cough in the previous 7 days is an important determinant of health-related quality of life impairment in stable COPD patients. PMID- 27695306 TI - Differences in physical activity according to mMRC grade in patients with COPD. AB - BACKGROUND: Physical activity (PA) is impaired from the early stages of COPD, is associated with a worsening of disease prognosis, and causes COPD patients to restrict their daily activities in order to avoid breathlessness. The development of a simple tool to estimate physical activity level (PAL) could be useful for the management of COPD. OBJECTIVES: We investigated the differences in PA according to the modified Medical Research Council (mMRC) grade in patients with COPD. METHODS: A cross-sectional study was performed on stable outpatients with COPD. PA was measured for 2 weeks using a triaxial accelerometer, and dyspnea grade was evaluated in all patients using the mMRC scale. RESULTS: Ninety-eight patients were recruited. Significant differences in PA duration were observed at all intensities according to the mMRC grade. Despite treatment with controller medications, 59.2% of COPD patients had low PAL, which was <1.5 metabolic equivalents multiplied by hour per day. COPD patients with an mMRC grade >=2, which was the most balanced cutoff point in the receiver operating characteristic curve, showed a higher reduction rate of PAL (80.0% at mMRC grade 2, 71.4% at mMRC grade 3, and 100% at mMRC grade 4). CONCLUSION: PA differed according to the mMRC grade, and mMRC grade >=2 could predict a low PAL. Therefore, assessment of breathlessness by the mMRC questionnaire would be useful to stratify the risks of reduced PA in COPD. PMID- 27695302 TI - Survey of Genes Involved in Biosynthesis, Transport, and Signaling of Phytohormones with Focus on Solanum lycopersicum. AB - Phytohormones control the development and growth of plants, as well as their response to biotic and abiotic stress. The seven most well-studied phytohormone classes defined today are as follows: auxins, ethylene, cytokinin, abscisic acid, jasmonic acid, gibberellins, and brassinosteroids. The basic principle of hormone regulation is conserved in all plants, but recent results suggest adaptations of synthesis, transport, or signaling pathways to the architecture and growth environment of different plant species. Thus, we aimed to define the extent to which information from the model plant Arabidopsis thaliana is transferable to other plants such as Solanum lycopersicum. We extracted the co-orthologues of genes coding for major pathway enzymes in A. thaliana from the translated genomes of 12 species from the clade Viridiplantae. Based on predicted domain architecture and localization of the identified proteins from all 13 species, we inspected the conservation of phytohormone pathways. The comparison was complemented by expression analysis of (co-) orthologous genes in S. lycopersicum. Altogether, this information allowed the assignment of putative functional equivalents between A. thaliana and S. lycopersicum but also pointed to some variations between the pathways in eudicots, monocots, mosses, and green algae. These results provide first insights into the conservation of the various phytohormone pathways between the model system A. thaliana and crop plants such as tomato. We conclude that orthologue prediction in combination with analysis of functional domain architecture and intracellular localization and expression studies are sufficient tools to transfer information from model plants to other plant species. Our results support the notion that hormone synthesis, transport, and response for most part of the pathways are conserved, and species-specific variations can be found. PMID- 27695307 TI - Noninvasive mechanical ventilation on the ward for severe COPD: still unresolved question of balance among safety and drawbacks? PMID- 27695309 TI - Correlates of disease-specific knowledge in Chinese patients with COPD. AB - BACKGROUND: This study aimed to determine the associations of various sociodemographic factors with the level of disease-specific knowledge among Hong Kong Chinese patients with COPD. METHODS: A cross-sectional survey of 100 Chinese adults with COPD recruited from outpatient clinics was conducted from September 2009 to September 2010. Data on the knowledge specific to COPD and patients' sociodemographics were collected from face-to-face interviews. Primary outcome of disease-specific knowledge was measured using 65-item Bristol COPD Knowledge Questionnaire (BCKQ), summing up the 65 items as the BCKQ overall score. Associations of sociodemographic factors with the BCKQ overall score were evaluated using the linear regression model. RESULTS: The mean BCKQ overall score of our patients was 41.01 (SD: 10.64). The knowledge in topics of "Smoking" and "Phlegm" achieved the first (3.97, SD: 0.82) and second (3.91, SD: 1.17) highest mean scores, respectively, while the topic of "Oral steroids" returned the lowest mean score of 1.89 (SD: 1.64). The BCKQ overall score progressively declined (P<0.001) with increase in education level, with the highest BCKQ overall score of 46.71 at no formal education among all subgroups. Compared to nondrinkers, current drinkers were associated with lower total BCKQ score. CONCLUSION: We found that among COPD patients in outpatient clinics, impairments in the level of COPD knowledge were evident in patients who were current drinkers or had higher level of education. PMID- 27695308 TI - Health-related quality of life in current smokers with COPD: factors associated with current smoking and new insights into sex differences. AB - Findings from studies that examined the association between health-related quality of life (HRQOL) and smoking status among COPD patients have been mixed. Moreover, factors associated with current smoking in COPD patients and differences by sex have not been fully elucidated. Data from the 2011 and 2012 Behavioral Risk Factor Surveillance System was used in this study. Four HRQOL indicators were examined in this study: general health, physical health, mental health, and activity limitations. General health was dichotomized into two groups: "excellent/very good/good" and "fair/poor", and the other three HRQOL indicators were dichotomized into <14 (infrequent) and >=14 (frequent) unhealthy days in the past 30 days. To examine HRQOL indicators in association with current versus former smoking and identify factors associated with current smoking, logistic regression models were used. Sex differences were explored. In COPD patients, current smokers compared to former smokers had significantly poor HRQOL on all subdomains: "fair/poor" general health (adjusted odds ratio [AOR]: 1.2 [95% confidence interval {CI}: 1.1-1.5]); poor physical health (AOR: 1.3 [CI: 1.1 1.5]); poor mental health (AOR: 1.8 [CI: 1.4-2.2]); and poor activity limitations (AOR: 1.5 [CI: 1.3-1.9]). HRQOL subdomains affected by current smoking differed by sex except activity limitations. General health (AOR: 1.5 [CI: 1.1-2.0]) and activity limitations (AOR: 1.6 [95% CI: 1.2-2.2]) in males and physical health (AOR: 1.3 [CI: 1.0-1.6]), mental health (AOR: 2.1 [CI: 1.7-2.6]), and activity limitations (AOR: 1.5 [CI: 1.2-1.9]) in females were significantly impaired due to current smoking. Factors associated with current smoking differed by sex except being unmarried and having less than a college degree, which were associated with current smoking in both males and females. These findings have important implications for health care providers in designing more effective interventions which tailor to and target specific subgroups for smoking cessation. PMID- 27695310 TI - Prevalence of comorbidities according to predominant phenotype and severity of chronic obstructive pulmonary disease. AB - BACKGROUND: In addition to lung involvement, several other diseases and syndromes coexist in patients with chronic obstructive pulmonary disease (COPD). Our purpose was to investigate the prevalence of idiopathic arterial hypertension (IAH), ischemic heart disease, heart failure, peripheral vascular disease (PVD), diabetes, osteoporosis, and anxious depressive syndrome in a clinical setting of COPD outpatients whose phenotypes (predominant airway disease and predominant emphysema) and severity (mild and severe diseases) were determined by clinical and functional parameters. METHODS: A total of 412 outpatients with COPD were assigned either a predominant airway disease or a predominant emphysema phenotype of mild or severe degree according to predictive models based on pulmonary functions (forced expiratory volume in 1 second/vital capacity; total lung capacity %; functional residual capacity %; and diffusing capacity of lung for carbon monoxide %) and sputum characteristics. Comorbidities were assessed by objective medical records. RESULTS: Eighty-four percent of patients suffered from at least one comorbidity and 75% from at least one cardiovascular comorbidity, with IAH and PVD being the most prevalent ones (62% and 28%, respectively). IAH prevailed significantly in predominant airway disease, osteoporosis prevailed significantly in predominant emphysema, and ischemic heart disease and PVD prevailed in mild COPD. All cardiovascular comorbidities prevailed significantly in predominant airway phenotype of COPD and mild COPD severity. CONCLUSION: Specific comorbidities prevail in different phenotypes of COPD; this fact may be relevant to identify patients at risk for specific, phenotype-related comorbidities. The highest prevalence of comorbidities in patients with mild disease indicates that these patients should be investigated for coexisting diseases or syndromes even in the less severe, pauci-symptomatic stages of COPD. The simple method employed to phenotype and score COPD allows these results to be translated easily into daily clinical practice. PMID- 27695311 TI - Systolic time intervals combined with Valsalva maneuver for the diagnosis of left ventricular dysfunction in COPD exacerbations. AB - BACKGROUND: The goal of this study was to determine the value of systolic time intervals and their change during Valsalva maneuver (VM) in the diagnosis of left ventricular dysfunction (LVD) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). METHODS: We included 166 patients admitted to the emergency department for AECOPD. Measurement of systolic time intervals included electromechanical activation time (EMAT), left ventricular ejection time (LVET), and EMAT/LVET ratio. These were performed at baseline and during the first strain phase of the VM using a computerized phonoelectrocardiographic method. The diagnosis of LVD was determined on the basis of clinical examination, echocardiography, and brain natriuretic peptide. The values of systolic time intervals were compared between patients with and without LVD; their diagnostic performance was assessed using the area under receiver operating characteristic (ROC) curve. RESULTS: Patients with LVD (n=95) had a significantly higher EMAT and lower LVET and EMAT/LVET ratio compared to patients without LVD (n=71); the area under ROC curve was 0.79, 0.88, and 0.90, respectively, for EMAT, LVET, and EMAT/LVET ratio. All baseline systolic time intervals changed significantly during VM in patients without LVD but they did not change in patients with LVD. The area under ROC curve increased to 0.84 and 0.93, respectively, for EMAT and EMAT/LVET ratio but did not change for LVET. CONCLUSION: Simple and noninvasive measurements of systolic time intervals combined with VM could be helpful to detect or rule out LVD in patients admitted to the emergency room for COPD excacerbation. The EMAT/LVET ratio seems to have the best diagnostic value. PMID- 27695313 TI - The use of high-flow nasal oxygen in COPD patients. PMID- 27695312 TI - Interleukin-16-producing NK cells and T-cells in the blood of tobacco smokers with and without COPD. AB - BACKGROUND: Long-term exposure to tobacco smoke causes local inflammation in the airways that involves not only innate immune cells, including NK cells, but also adaptive immune cells such as cytotoxic (CD8+) and helper (CD4+) T-cells. We have previously demonstrated that long-term tobacco smoking increases extracellular concentration of the CD4+-recruiting cytokine interleukin (IL)-16 locally in the airways. Here, we hypothesized that tobacco smoking alters IL-16 biology at the systemic level and that this effect involves oxygen free radicals (OFR). METHODS: We quantified extracellular IL-16 protein (ELISA) and intracellular IL-16 in NK cells, T-cells, B-cells, and monocytes (flow cytometry) in blood samples from long-term tobacco smokers with and without chronic obstructive pulmonary disease (COPD) and in never-smokers. NK cells from healthy blood donors were stimulated with water-soluble tobacco smoke components (cigarette smoke extract) with or without an OFR scavenger (glutathione) in vitro and followed by quantification of IL-16 protein. RESULTS: The extracellular concentrations of IL-16 protein in blood did not display any substantial differences between groups. Notably, intracellular IL-16 protein was detected in all types of blood leukocytes. All long-term smokers displayed a decrease in this IL-16 among NK cells, irrespective of COPD status. Further, both NK and CD4+ T-cell concentrations displayed a negative correlation with pack-years. Moreover, cigarette smoke extract caused release of IL-16 protein from NK cells in vitro, and this was not affected by glutathione, in contrast to the decrease in intracellular IL-16, which was prevented by this drug. CONCLUSION: Long-term exposure to tobacco smoke does not markedly alter extracellular concentrations of IL-16 protein in blood. However, it does decrease the intracellular IL-16 concentrations in blood NK cells, the latter effect involving OFR. Thus, long-term tobacco smoking exerts an impact at the systemic level that involves NK cells; innate immune cells that are critical for host defense against viruses and tumors - conditions that are overrepresented among smokers. PMID- 27695314 TI - Myocardial performance index correlates with the BODE index and affects quality of life in COPD patients. AB - BACKGROUND AND OBJECTIVE: COPD, a systemic illness associated with the impairment of different organs, affects patient prognosis and quality of life. The aim of this study was to evaluate the association between right ventricle (RV) function, the BODE (body mass index, airflow obstruction, dyspnea, and exercise capacity) index (a multifunctional scale for the assessment of mortality risk), and quality of life in patients with COPD. METHODS: A cross-sectional study was carried out in 107 outpatients presenting with stable COPD who underwent clinical assessment, spirometry, arterial blood gas analyses, a 6-minute walk test, electrocardiography, and echocardiogram and who responded to the Saint George's Respiratory Questionnaire (SGRQ). RESULTS: Among the study subjects, 53% (57/107) were males, and the mean age was 65.26+/-8.81 years. A positive correlation was observed between RV dysfunction measured by the myocardial performance index using tissue Doppler (MPIt) and the BODE index, even after adjustment for age and partial pressure of oxygen (r2=0.47; P<0.01). Patients with alterations in the MPIt had worse quality of life, and a statistically significant difference was found for different domains of the SGRQ. Patients with a normal MPIt had a mean total score of 46.2+/-18.6, whereas for those with MPIt alterations, the mean total score was 61.6+/-14.2 (P=0.005). These patients had a 1.49-fold increased risk of exhibiting SGRQ total score above the upper limit of the 95% CI (P=0.01). CONCLUSION: The findings of this study suggest that RV dysfunction as measured by the MPIt was associated with impairment in quality of life and a worse BODE index in COPD patients, irrespective of age and hypoxemia status. PMID- 27695315 TI - Breakdown of lung framework and an increase in pores of Kohn as initial events of emphysema and a cause of reduction in diffusing capacity. AB - PURPOSE: Pulmonary emphysema is the pathological prototype of chronic obstructive pulmonary disease and is also associated with other lung diseases. We considered that observation with different approaches may provide new insights for the pathogenesis of emphysema. PATIENTS AND METHODS: We reviewed tissue blocks of the lungs of 25 cases with/without emphysema and applied a three-dimensional observation method to the blocks. Based on the three-dimensional characteristics of the alveolar structure, we considered one face of the alveolar polyhedron as a structural unit of alveoli and called it a framework unit (FU). We categorized FUs based on their morphological characteristics and counted their number to evaluate the destructive changes in alveoli. We also evaluated the number and the area of pores of Kohn in FUs. We performed linear regression analysis to estimate the effect of these data on pulmonary function tests. RESULTS: In multivariable regression analysis, a decrease in the number of FUs without an alveolar wall led to a significant decrease in the diffusing capacity of the lung for carbon monoxide (DLCO) and DLCO per unit alveolar volume, and an increase in the area of pores of Kohn had a significant effect on an increase in residual capacity. CONCLUSION: A breakdown in the lung framework and an increase in pores of Kohn are associated with a decrease in DLCO and DLCO per unit alveolar volume with/without emphysema. PMID- 27695317 TI - Preference for different relaxation techniques by COPD patients: comparison between six techniques. AB - BACKGROUND: A review of the effectiveness of relaxation techniques for chronic obstructive pulmonary disease patients has shown inconsistent results, but studies have varied in terms of technique and outcome measures. AIM: To determine patient preference for different relaxation techniques. METHODS: Chronic obstructive pulmonary disease patients were presented with six techniques via a DVD and asked to rate the techniques in terms of effectiveness, rank in order of likely use, and comment. RESULTS: Patients differed in the technique preferred and reason for that preference, but the most commonly preferred technique both for effectiveness and ease of use was "thinking of a nice place" followed by progressive relaxation and counting. Familiarity and ease of activity were commonly given reasons for preference. CONCLUSION: Rather than providing patients with a single technique that they might find difficult to implement, these results suggest that it would be better to give a choice. "Thinking of a nice place" is a popular but under-investigated technique. PMID- 27695316 TI - What else should we know about experiencing COPD? A narrative review in search of patients' psychological burden alleviation. AB - The present paper is a narrative review focusing on the psychological impact, identification of protective factors, and interventions minimizing the psychological burdens of chronic obstructive pulmonary disease (COPD). The research reviews studies on neurocognitive functions, personality, emotional problems, and health-related quality of life. This is done with regard to resources as well as activities enabling or enhancing a patient's adaptation. PubMed and PsychArticles databases were searched for relevant medical (eg, CODP, emphysema), psychopathology (eg, depression), and psychological (eg, personality) keywords, followed by hand search. After application of the inclusion and exclusion criteria, the search resulted in 82 articles and book chapters. The choice was based on evidence accepted by evidence-based medicine, although at different levels of strength. Psychological experiencing of COPD appears to be very unequally represented with scientific research on emotional problems and functioning decrease significantly outnumbering those addressing resources or effective interventions. As our initial literature search called for an urgent need for further exploration, we have carefully pointed out numerous areas where the knowledge on how to protect or restore psychological well-being among COPD patients should be broadened. PMID- 27695318 TI - Folate-conjugated boron nitride nanospheres for targeted delivery of anticancer drugs. AB - With its unique physical and chemical properties and structural similarity to carbon, boron nitride (BN) has attracted considerable attention and found many applications. Biomedical applications of BN have recently started to emerge, raising great hopes in drug and gene delivery. Here, we developed a targeted anticancer drug delivery system based on folate-conjugated BN nanospheres (BNNS) with receptor-mediated targeting. Folic acid (FA) was successfully grafted onto BNNS via esterification reaction. In vitro cytotoxicity assay showed that BNNS-FA complexes were non-toxic to HeLa cells up to a concentration of 100 MUg/mL. Then, doxorubicin hydrochloride (DOX), a commonly used anticancer drug, was loaded onto BNNS-FA complexes. BNNS-FA/DOX complexes were stable at pH 7.4 but effectively released DOX at pH 5.0, which exhibited a pH sensitive and sustained release pattern. BNNS-FA/DOX complexes could be recognized and specifically internalized by HeLa cells via FA receptor-mediated endocytosis. BNNS-FA/DOX complexes exhibited greater cytotoxicity to HeLa cells than free DOX and BNNS/DOX complexes due to the increased cellular uptake of DOX mediated by the FA receptor. Therefore, BNNS-FA complexes had strong potential for targeted cancer therapy. PMID- 27695319 TI - Synthesis of composite magnetic nanoparticles Fe3O4 with alendronate for osteoporosis treatment. AB - Osteoporosis is a result of imbalance between bone formation by osteoblasts and resorption by osteoclasts (OCs). In the present study, we investigated the potential of limiting the aggravation of osteoporosis by reducing the activity of OCs through thermolysis. The proposed method is to synthesize bisphosphonate (Bis)-conjugated iron (II, III) oxide (Fe3O4) nanoparticles and incorporate them into OCs. The cells should be subsequently exposed to radiofrequency (RF) to induce thermolysis. In this study, particles of Fe3O4 were first synthesized by chemical co-precipitation and then coated with dextran (Dex). The Dex/Fe3O4 particles were then conjugated with Bis to form Bis/Dex/Fe3O4. Transmission electron microscopy revealed that the average diameter of the Bis/Dex/Fe3O4 particles was ~20 nm. All three kinds of nanoparticles were found to have cubic inverse spinel structure of Fe3O4 by the X-ray diffraction analysis. Fourier transform infrared spectroscopy confirmed that the Dex/Fe3O4 and Bis/Dex/Fe3O4 nanoparticles possessed their respective Dex and Bis functional groups, while a superconducting quantum interference device magnetometer measured the magnetic moment to be 24.5 emu. In addition, the Bis/Dex/Fe3O4 nanoparticles were fully dispersed in double-distilled water. Osteoblasts and OCs were individually cultured with the nanoparticles, and an MTT assay revealed that they were non cytotoxic. An RF system (42 kHz and 450 A) was used to raise the temperature of the nanoparticles for 20 minutes, and the thermal effect was found to be sufficient to destroy OCs. Furthermore, in vivo studies verified that nanoparticles were indeed magnetic resonance imaging contrast agents and that they accumulated after being injected into the body of rats. In conclusion, we developed a water-dispersible magnetic nanoparticle that had RF-induced thermogenic properties, and the results indicated that the Bis/Dex/Fe3O4 nanoparticle had the potential for controlling osteoporosis. PMID- 27695320 TI - The effect of neutral-surface iron oxide nanoparticles on cellular uptake and signaling pathways. AB - In recent years, iron oxide nanoparticles (IONPs) have been applied widely to biomedical fields. However, the relationship between the physicochemical properties of IONPs and their biological behavior is not fully understood yet. We prepared 3-methacryloxypropyltrimethoxysilane (MPS)-coated IONPs, which have a neutral hydrophobic surface, and compared their biological behavior to that of Resovist (ferucarbotran), a commercialized IONP formulation modified with carboxymethyl dextran. The rate of MPS-IONP uptake by human aortic endothelial cells (HAoECs) was higher than ferucarbotran uptake, indicating that the neutral hydrophobic nature of MPS-IONPs allowed them to be absorbed more readily through the plasma membrane. However, the signaling pathways activated by MPS-IONPs and ferucarbotran were comparable, suggesting that surface charge is not a key factor for inducing changes in HAoECs. In vivo fate analysis showed that MPS-IONPs accumulated for longer periods in tissues than hydrophilic ferucarbotran. These findings could enlarge our understanding of NP behavior for advanced applications in the biomedical field. PMID- 27695321 TI - Effective combination treatment of lung cancer cells by single vehicular delivery of siRNA and different anticancer drugs. AB - In recent years, lung cancer has become one of the fastest growing cancers in the world. Thus, the development of efficient combination therapy to treat lung cancer has attracted significant attention in the cancer therapy field. In this article, we developed a single vehicle drug delivery system, based on quantum dot (QD) nanoparticles, to deliver small interfering RNA (siRNA; target Bcl-2) and different anticancer drugs (carboplatin, paclitaxel, and doxorubicin) simultaneously for treating A549 lung cancer cells efficiently by combination therapy. The QD nanoparticles were conjugated with l-arginine (l-Arg) and different kinds of hydroxypropyl-cyclodextrins (HP-alpha-CDs, HP-beta-CDs, and HP gamma-CDs) on the surface to form the delivery nanocarriers (QD nanocarriers). They were able to not only bind and transport the siRNA through electrostatic interactions with l-Arg residues but also accommodate various disparate anticancer drugs using different HP-CD modifications. Compared with free drug treatments, the use of QD nanocarriers to deliver Bcl-2 siRNA and different anticancer drugs simultaneously exerted a threefold to fourfold increase in cytotoxicity in A549 cells, which greatly improved the treatment efficacy through combined action. Furthermore, the QD nanocarriers could be used as a probe for real-time imaging of the drug delivery and release because of their strong fluorescence properties. These findings indicate that multifunctional QD nanocarriers hold great promise as a powerful tool for combination therapy for lung cancer. PMID- 27695322 TI - Iron oxide nanoparticles modulate lipopolysaccharide-induced inflammatory responses in primary human monocytes. AB - Co-stimulation of the immune system to more than one agent concomitantly is very common in real life, and considering the increasing use of engineered nanoparticles and nanomaterials, it is highly relevant to assess the ability of these materials to modulate key innate immune responses, which has not yet been studied in detail. We investigated the immunomodulatory effects of 10 nm and 30 nm iron oxide nanoparticles (IONPs) on primary human monocytes in the presence and absence of Toll-like receptor 4 agonist lipopolysaccharide (LPS). Prior to the cell studies, we characterized the physicochemical properties of the nanoparticles in cell culture medium and ensured that the nanoparticles were free from biological contamination. Cellular uptake of the IONPs in monocytes was assessed using transmission electron microscopy. Using enzyme-linked immunosorbent assay, we found that the IONPs per se did not induce the production of proinflammatory cytokines tumor necrosis factor-alpha, interleukin-6, and interleukin-1beta. However, the IONPs had the ability to suppress LPS-induced nuclear factor kappa B activation and production of proinflammatory cytokines in primary human monocytes in an LPS and a particle dose-dependent manner. Using confocal microscopy and fluorescently labeled LPS, we showed that the effects correlated with impaired LPS internalization by monocytes in the presence of IONPs, which could be partly explained by LPS adsorption onto the nanoparticle surface. Additionally, the results from particle pretreatment experiments indicate that other cellular mechanisms might also play a role in the observed effects, which warrants further studies to elucidate the additional mechanisms underlying the capacity of IONPs to alter the reactivity of monocytes to LPS and to mount an appropriate cellular response. PMID- 27695324 TI - Metal oxide nanoparticles interact with immune cells and activate different cellular responses. AB - Besides cell death, nanoparticles (Nps) can induce other cellular responses such as inflammation. The potential immune response mediated by the exposure of human lymphoid cells to metal oxide Nps (moNps) was characterized using four different moNps (CeO2, TiO2, Al2O3, and ZnO) to study the three most relevant mitogen activated protein kinase subfamilies and the nuclear factor kappa-light-chain enhancer of the activated B-cell inhibitor, IkappaBalpha, as well as the expression of several genes by immune cells incubated with these Nps. The moNps activated different signaling pathways and altered the gene expression in human lymphocyte cells. The ZnO Nps were the most active and the release of Zn2+ ions was the main mechanism of toxicity. CeO2 Nps induced the smallest changes in gene expression and in the IkappaBalpha protein. The effects of the particles were strongly dependent on the type and concentration of the Nps and on the cell activation status prior to Np exposure. PMID- 27695323 TI - Dual-function synthetic peptide derived from BMP4 for highly efficient tumor targeting and antiangiogenesis. AB - Angiogenesis plays a critical role in the growth and metastasis of cancer, and growth factors released from cancer promote blood-vessel formation in the tumor microenvironment. The angiogenesis is accelerated via interactions of growth factors with the high-affinity receptors on cancer cells. In particular, heparan sulfate proteoglycans (HSPGs) on the surface of cancer cells have been shown to be important in many aspects of determining a tumor's phenotype and development. Specifically, the regulation of the interactions between HSPGs and growth factors results in changes in tumor progression. A peptide with heparin-binding (HBP) activity has been developed and synthesized to inhibit tumor growth via the prevention of angiogenesis. We hypothesized that HBP could inhibit the interaction of growth factors and HSPGs on the surface of cancer cells, decrease paracrine signaling in endothelial cells (ECs), and finally decrease angiogenesis in the tumor microenvironment. In this study, we found that HBP had antiangiogenic effects in vitro and in vivo. The conditioned media obtained from a breast cancer cell line treated with HBP were used to culture human umbilical vein ECs (HUVECs) to evaluate the antiangiogenic effect of HBP on ECs. HBP effectively inhibited the migration, invasion, and tube formation of HUVECs in vitro. In addition, the expressions of angiogenesis-mediating factors, including ERK, FAK, and Akt, were considerably decreased. HBP also decreased the levels of invasive factors, including MMP2 and MMP9, secreted by the HUVECs. We demonstrated significant suppression of tumor growth in a breast cancer xenograft model and enhanced distribution of HBP at the site of tumors. Taken together, our results show that HBP has antiangiogenic effects on ECs, and suggest that it may serve as a potential antitumor agent through control of the tumor microenvironment. PMID- 27695326 TI - Comparative study of proteasome inhibitory, synergistic antibacterial, synergistic anticandidal, and antioxidant activities of gold nanoparticles biosynthesized using fruit waste materials. AB - The aim of this study was to compare the biological synthesis of gold nanoparticles (AuNPs) generated using the aqueous extracts of outer oriental melon peel (OMP) and peach. The synthesized OMP-AuNPs and peach extract (PE) AuNPs were characterized by ultraviolet-visible spectroscopy, field emission scanning electron microscopy, energy dispersive X-ray analysis, X-ray powder diffraction, Fourier transform infrared spectroscopy, and thermogravimetric analysis. The surface plasmon resonance spectra were obtained at 545 nm and 540 nm for OMP-AuNPs and PE-AuNPs, respectively. The estimated absolute crystallite size of the synthesized AuNPs was calculated to be 78.11 nm for OMP-AuNPs and 39.90 nm for PE-AuNPs based on the Scherer equation of the X-ray powder diffraction peaks. Fourier transform infrared spectroscopy results revealed the involvement of bioactive compounds present in OMP and peach extracts in the synthesis and stabilization of synthesized AuNPs. Both the OMP-AuNPs and PE-AuNPs showed a strong antibacterial synergistic activity when combined with kanamycin (9.38-20.45 mm inhibition zones) and rifampicin (9.52-25.23 mm inhibition zones), and they also exerted a strong synergistic anticandidal activity (10.09-15.47 mm inhibition zones) when combined with amphotericin B against five pathogenic Candida species. Both the OMP-AuNPs and PE-AuNPs exhibited a strong antioxidant potential in terms of 1,1-diphenyl-2-picrylhydraxyl radical scavenging, nitric oxide scavenging, 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging, and a reducing power, along with a strong proteasome inhibitory potential that could be useful in cancer drug delivery and cancer treatments. The PE-AuNPs showed comparatively higher activity than OMP-AuNPs, which could be attributed to the presence of rich bioactive compounds in the PE that acted as reducing and capping agents in the synthesis of PE-AuNPs. Overall, the results of the current investigation highlighted a novel green technology for the synthesis of AuNPs using food waste materials and their potential applications in the biomedical, pharmaceutical, and cosmetic industries. PMID- 27695325 TI - Surface biofunctionalized CdS and ZnS quantum dot nanoconjugates for nanomedicine and oncology: to be or not to be nanotoxic? AB - Herein, for the first time, we demonstrated that novel biofunctionalized semiconductor nanomaterials made of Cd-containing fluorescent quantum dot nanoconjugates with the surface capped by an aminopolysaccharide are not biologically safe for clinical applications. Conversely, the ZnS-based nanoconjugates proved to be noncytotoxic, considering all the parameters investigated. The results of in vitro cytotoxicity were remarkably dependent on the chemical composition of quantum dot (CdS or ZnS), the nature of the cell (human cancerous and embryonic types), and the concentration and time period of exposure to these nanomaterials, caused by the effects of Cd2+ on the complex nanotoxicity pathways involved in cellular uptake. Unexpectedly, no decisive evidence of nanotoxicity of CdS and ZnS conjugates was observed in vivo using intravenous injections in BALB/c mice for 30 days, with minor localized fluorescence detected in liver tissue specimens. Therefore, these results proved that CdS nanoconjugates could pose an excessive threat for clinical applications due to unpredicted and uncorrelated in vitro and in vivo responses caused by highly toxic cadmium ions at biointerfaces. On the contrary, ZnS nanoconjugates proved that the "safe by design" concept used in this research (ie, biocompatible core-shell nanostructures) could benefit a plethora of applications in nanomedicine and oncology. PMID- 27695327 TI - Fabrication of gelatin methacrylate/nanohydroxyapatite microgel arrays for periodontal tissue regeneration. AB - INTRODUCTION: Periodontitis is a chronic infectious disease and is the major cause of tooth loss and other oral health issues around the world. Periodontal tissue regeneration has therefore always been the ultimate goal of dentists and researchers. Existing fabrication methods mainly focused on a top-down tissue engineering strategy in which several drawbacks remain, including low throughput and limited diffusion properties resulting from a large sample size. Gelatin methacrylate (GelMA) is a kind of photocrosslinkable and biocompatible hydrogel, with the capacities of enabling cell encapsulation and regeneration of functional tissues. Here, we developed a novel method to fabricate GelMA/nanohydroxylapatite (nHA) microgel arrays using a photocrosslinkable strategy. The viability, proliferation, and osteogenic differentiation and in vivo osteogenesis of human periodontal ligament stem cells (hPDLSCs) encapsulated in microgels were evaluated. The results suggested that such microgels provide great potential for periodontal tissue repair and regeneration. METHODS: Microgel arrays were fabricated by blending different weight ratios of GelMA and nHA. hPDLSCs were encapsulated in GelMA/nHA microgels of various ratios for a systematic evaluation of cell viability, proliferation, and osteogenic differentiation. In vivo osteogenesis in nude mice was also studied. RESULTS: The GelMA/nHA microgels exhibited appropriate microarchitecture, mechanical strength, and surface roughness, thus enabling cell adhesion and proliferation. Additionally, the GelMA/nHA microgels (10%/2% w/v) enhanced the osteogenic differentiation of hPDLSCs by elevating the expression levels of osteogenic biomarker genes, such as ALP, BSP, OCN, and RUNX2. In vivo ectopic transplantation results showed that GelMA/nHA microgels (10%/2% w/v) increased mineralized tissue formation with abundant vascularization, compared with the 1%, 3%, and the pure GelMA group. CONCLUSION: The GelMA/nHA microgels (10%/2% w/v) facilitated hPDLSCs viability, proliferation, and osteogenic differentiation in vitro and further promoted new bone formation in vivo, suggesting that the GelMA/nHA microgels (10%/2% w/v) provide great potential for periodontal tissue regeneration. PMID- 27695329 TI - Monte Carlo and analytic simulations in nanoparticle-enhanced radiation therapy. AB - Analytical and Monte Carlo simulations have been used to predict dose enhancement factors in nanoparticle-enhanced X-ray radiation therapy. Both simulations predict an increase in dose enhancement in the presence of nanoparticles, but the two methods predict different levels of enhancement over the studied energy, nanoparticle materials, and concentration regime for several reasons. The Monte Carlo simulation calculates energy deposited by electrons and photons, while the analytical one only calculates energy deposited by source photons and photoelectrons; the Monte Carlo simulation accounts for electron-hole recombination, while the analytical one does not; and the Monte Carlo simulation randomly samples photon or electron path and accounts for particle interactions, while the analytical simulation assumes a linear trajectory. This study demonstrates that the Monte Carlo simulation will be a better choice to evaluate dose enhancement with nanoparticles in radiation therapy. PMID- 27695328 TI - The synergistic effect of TiO2 nanoporous modification and platelet-rich plasma treatment on titanium-implant stability in ovariectomized rats. AB - For several decades, titanium and its alloys have been commonly utilized for endosseous implantable materials, because of their good mechanical properties, chemical resistance, and biocompatibility. But associated low bone mass, wear and loss characteristics, and high coefficients of friction have limited their long term stable performance, especially in certain abnormal bone-metabolism conditions, such as postmenopausal osteoporosis. In this study, we investigated the effects of platelet-rich plasma (PRP) treatment and TiO2 nanoporous modification on the stability of titanium implants in osteoporotic bone. After surface morphology, topographical structure, and chemical changes of implant surface had been detected by scanning electron microscopy (SEM), atomic force microscopy, contact-angle measurement, and X-ray diffraction, we firstly assessed in vivo the effect of PRP treatment on osseointegration of TiO2-modified implants in ovariectomized rats by microcomputed tomography examinations, histology, biomechanical testing, and SEM observation. Meanwhile, the potential molecular mechanism involved in peri-implant osseous enhancement was also determined by quantitative real-time polymerase chain reaction. The results showed that this TiO2-modified surface was able to lead to improve bone implant contact, while PRP treatment was able to increase the implant surrounding bone mass. The synergistic effect of both was able to enhance the terminal force of implants drastically in biomechanical testing. Compared with surface modification, PRP treatment promoted earlier osteogenesis with increased expression of the RUNX2 and COL1 genes and suppressed osteoclastogenesis with increased expression of OPG and decreased levels of RANKL. These promising results show that PRP treatment combined with a TiO2-nanomodified surface can improve titanium-implant biomechanical stability in ovariectomized rats, suggesting a beneficial effect to support the success of implants in osteoporotic bone. PMID- 27695331 TI - Predicting episodic memory performance using different biomarkers: results from Argentina-Alzheimer's Disease Neuroimaging Initiative. AB - PURPOSE: Argentina-Alzheimer's Disease Neuroimaging Initiative (Arg-ADNI) is the first ADNI study to be performed in Latin America at a medical center with the appropriate infrastructure. Our objective was to describe baseline characteristics and to examine whether biomarkers related to Alzheimer's disease (AD) physiopathology were associated with worse memory performance. PATIENTS AND METHODS: Fifteen controls and 28 mild cognitive impairment and 13 AD dementia subjects were included. For Arg-ADNI, all biomarker parameters and neuropsychological tests of ADNI-II were adopted. Results of positron emission tomography (PET) with fluorodeoxyglucose and 11C-Pittsburgh compound-B (PIB-PET) were available from all participants. Cerebrospinal fluid biomarker results were available from 39 subjects. RESULTS: A total of 56 participants were included and underwent baseline evaluation. The three groups were similar with respect to years of education and sex, and they differed in age (F=5.10, P=0.01). Mean scores for the baseline measurements of the neuropsychological evaluation differed significantly among the three groups at P<0.001, showing a continuum in their neuropsychological performance. No significant correlations were found between the principal measures (long-delay recall, C-Pittsburgh compound-B scan, left hippocampal volume, and APOEepsilon4) and either age, sex, or education (P>0.1). Baseline amyloid deposition and left hippocampal volume separated the three diagnostic groups and correlated with the memory performance (P<0.001). CONCLUSION: Cross-sectional analysis of baseline data revealed links between cognition, structural changes, and biomarkers. Follow-up of a larger and more representative cohort, particularly analyzing cerebrospinal fluid and brain biomarkers, will allow better characterization of AD in our country. PMID- 27695332 TI - The positive effects of high-frequency right dorsolateral prefrontal cortex repetitive transcranial magnetic stimulation on memory, correlated with increases in brain metabolites detected by proton magnetic resonance spectroscopy in recently detoxified alcohol-dependent patients. AB - OBJECTIVE: To explore the effect of right dorsolateral prefrontal cortex (DLPFC) repetitive transcranial magnetic stimulation (rTMS) on memory, and its correlation with levels of hippocampal brain metabolites detected by proton magnetic resonance spectroscopy (1H-MRS) in recently detoxified alcohol-dependent patients. MATERIALS AND METHODS: In this randomized, double-blind sham-controlled trial, alcohol-dependent patients were enrolled and randomized into two groups: the experimental group (rTMS, 10 Hz, on right DLPFC, 20 sessions) and the control group (sham stimulation). Memory function was assessed using Hopkins Verbal Learning Test-Revised (HVLT-R) and Brief Visuospatial Memory Test-Revised (BVMT R) before and after treatment. 1H-MRS was used to detect the levels of N-acetyl aspartic acid (NAA), choline (Cho), and creatine (Cr) in bilateral hippocampi before and after treatment. RESULTS: Thirty-eight patients (18 in the experimental group and 20 in the control group) were included in the analyses. The experimental group showed significantly greater changes in HVLT-R, BVMT-R, NAA/Cr, and Cho/Cr after rTMS from baseline than the control group. The percentage change in BVMT-R and HVLT-R correlated with the percentage change in NAA/Cr and Cho/Cr in the right brain. CONCLUSION: High-frequency right DLPFC rTMS was associated with improvement in memory dysfunction, which is correlated with levels of hippocampal brain metabolites detected by 1H-MRS in recently detoxified alcohol-dependent patients. PMID- 27695333 TI - The role of NMDAR antibody in the etiopathogenesis of schizophrenia. AB - Many authors have reported the presence of serum NMDAR antibodies in varying proportions of patients with schizophrenia; however, many others have not been able to confirm this. Because of the contradictory findings reported in various studies, more definitive research on this issue is required. Hence, we have investigated the NR1 subunit of NMDAR antibodies in patients with schizophrenia (n=49) and healthy controls (n=48). None of the investigated patients with schizophrenia and none of the healthy controls showed positive antibody against the NR1 subunit of the NMDAR. On the basis of this result, we conclude that the NR1 subunit of the NMDAR antibodies does not seem to have a role in schizophrenia. PMID- 27695334 TI - Effects of paroxetine-mediated inhibition of GRK2 expression on depression and cardiovascular function in patients with myocardial infarction. AB - BACKGROUND: Paroxetine is a selective serotonin reuptake inhibitor utilized in the treatment of depression and anxiety disorders. Recent studies have identified paroxetine as a G protein-coupled receptor kinase-2 (GRK2) inhibitor capable of reversing cardiac dysfunction and remodeling in experimental models of acute myocardial infarction (AMI). We determine the clinical importance of paroxetine on cardiac functions in patients having AMI with depression (AMID) in comparison with fluoxetine, an unrelated selective serotonin reuptake inhibitor that does not inhibit GRK2. METHODS: Diagnosis of depression was based on the 17-item Hamilton Depression Scale and Self-rating Depression Scale in AMI patients after hospital admission. AMID patients were randomly assigned to paroxetine or fluoxetine for treatment of depression. Heart rate variability and cardiac function were evaluated. GRK2 protein levels were measured using peripheral lymphocytes and Western blot. RESULTS: GRK2 expression in AMID patients was significantly higher than that in AMI patients without depression. In AMID patients, GRK2 levels were positively correlated with the 17-item Hamilton Depression Scale and the Self-rating Depression Scale scores, and negatively correlated with heart rate variability. Treatment of AMID patients with paroxetine significantly reduced the expression of GRK2, normalized the autonomic nervous system function, and improved cardiac performance. In contrast, fluoxetine normalized the autonomic nervous system but did not reduce the expression of GRK2 nor improved cardiac performance. CONCLUSION: This study suggests that paroxetine is effective for improving cardiac function in patients with AMID and such effect correlates with GRK2 reduction. PMID- 27695330 TI - Demineralization-remineralization dynamics in teeth and bone. AB - Biomineralization is a dynamic, complex, lifelong process by which living organisms control precipitations of inorganic nanocrystals within organic matrices to form unique hybrid biological tissues, for example, enamel, dentin, cementum, and bone. Understanding the process of mineral deposition is important for the development of treatments for mineralization-related diseases and also for the innovation and development of scaffolds. This review provides a thorough overview of the up-to-date information on the theories describing the possible mechanisms and the factors implicated as agonists and antagonists of mineralization. Then, the role of calcium and phosphate ions in the maintenance of teeth and bone health is described. Throughout the life, teeth and bone are at risk of demineralization, with particular emphasis on teeth, due to their anatomical arrangement and location. Teeth are exposed to food, drink, and the microbiota of the mouth; therefore, they have developed a high resistance to localized demineralization that is unmatched by bone. The mechanisms by which demineralization-remineralization process occurs in both teeth and bone and the new therapies/technologies that reverse demineralization or boost remineralization are also scrupulously discussed. Technologies discussed include composites with nano- and micron-sized inorganic minerals that can mimic mechanical properties of the tooth and bone in addition to promoting more natural repair of surrounding tissues. Turning these new technologies to products and practices would improve health care worldwide. PMID- 27695335 TI - Expanded DMPK repeats in dizygotic twins referred for diagnosis of autism versus absence of expanded DMPK repeats at screening of 330 children with autism. AB - Myotonic dystrophy type 1 (DM1) belongs to the broad spectrum of genetic disorders associated with autism spectrum disorders (ASD). ASD were reported predominantly in congenital and early childhood forms of DM1. We describe dizygotic twin boys with ASD who were referred for routine laboratory genetic testing and in whom karyotyping, FMR1 gene testing, and single nucleotide polymorphism array analysis yielded negative results. The father of the boys was later diagnosed with suspected DM1, and testing revealed characteristic DMPK gene expansions in his genome as well as in the genomes of both twins and their elder brother, who also suffered from ASD. In accord with previous reports on childhood forms of DM1, our patients showed prominent neuropsychiatric phenotypes characterized especially by hypotonia, developmental and language delay, emotional and affective lability, lowered adaptability, and social withdrawal. The experience with this family and multiple literature reports of ASD in DM1 on the one side but the lack of literature data on the frequency of DMPK gene expansions in ASD patients on the other side prompted us to screen the DMPK gene in a sample of 330 patients with ASD who were first seen by a geneticist before they were 10 years of age, before the muscular weakness, which may signal DM1, usually becomes obvious. The absence of any DMPK gene expansions in this cohort indicates that targeted DMPK gene testing can be recommended only in ASD patients with specific symptoms or family history suggestive of DM1. PMID- 27695336 TI - Varenicline improves motor and cognitive symptoms in early Huntington's disease. AB - The aim of this study was to describe the effects of varenicline, a smoking cessation aid that acts as a nicotinic agonist, on cognitive function in patients with early clinical Huntington's disease (HD) who were current smokers. Three gene-positive patients transitioning to symptomatic HD were evaluated using the Unified Huntington's Disease Rating Scale part I and III (motor and behavioral subscales) at baseline and after 4 weeks of treatment. Cognitive function was assessed using a touch screen computer-based neurocognitive test battery (IntegNeuro(r)). Varenicline (1 mg twice daily) significantly improved performance in executive function and emotional recognition tasks. Our case reports describe no clinically significant adverse effects and suggest that varenicline improves aspects of cognitive function in patients with early HD. A randomized controlled study is now underway. PMID- 27695337 TI - Clinical prediction rules for failed nonoperative reduction of intussusception. AB - PURPOSE: The nonoperative reduction of intussusception in children can be performed safely if there are no contraindications. Many risk factors associated with failed reduction were defined. The aim of this study was to develop a scoring system for predicting the failure of nonoperative reduction using various determinants. PATIENTS AND METHODS: The data were collected from Chiang Mai University Hospital and Siriraj Hospital from January 2006 to December 2012. Inclusion criteria consisted of patients with intussusception aged 0-15 years with no contraindications for nonoperative reduction. The clinical prediction rules were developed using significant risk factors from the multivariable analysis. RESULTS: A total of 170 patients with intussusception were included in the study. In the final analysis model, 154 patients were used for identifying the significant risk factors of failure of reduction. Ten factors clustering by the age of 3 years were identified and used for developing the clinical prediction rules, and the factors were as follows: body weight <12 kg (relative risk [RR] =1.48, P=0.004), duration of symptoms >48 hours (RR =1.26, P<0.001), vomiting (RR =1.63, P<0.001), rectal bleeding (RR =1.50, P<0.001), abdominal distension (RR =1.60, P=0.003), temperature >37.8 degrees C (RR =1.51, P<0.001), palpable mass (RR =1.26, P<0.001), location of mass (left over right side RR =1.48, P<0.001), ultrasound showed poor prognostic signs (RR =1.35, P<0.001), and the method of reduction (hydrostatic over pneumatic, RR =1.34, P=0.023). Prediction scores ranged from 0 to 16. A high-risk group (scores 12-16) predicted a greater chance of reduction failure (likelihood ratio of positive [LR+] =18.22, P<0.001). A low-risk group (score 0-11) predicted a lower chance of reduction failure (LR+ =0.79, P<0.001). The performance of the scoring model was 80.68% (area under the receiver operating characteristic curve). CONCLUSION: This scoring guideline was used to predict the results of nonoperative reduction and forecast the prognosis of the failed reduction. The usefulness of these prediction scores is for informing the parents before the reduction. This scoring system can be used as a guide to promote the possible referral of the cases to tertiary centers with facilities for nonoperative reduction if possible. PMID- 27695338 TI - Association of low serum aluminum level with mortality in hemodialysis patients. AB - BACKGROUND: The National Kidney Foundation-Kidney Disease Outcomes Quality Initiative recommends that the serum aluminum level (SAL) should be below 20 ug/L for patients with maintenance hemodialysis (MHD). However, serum aluminum may have toxic effects on MHD patients even when it is in the apparently acceptable range (below 20 ug/L). METHODS: The Medical Ethics Committee approved this study. Initially, 954 MHD patients in dialysis centers were recruited. A total of 901 patients met the inclusion criteria and were followed-up for 1 year. Patients were stratified by SAL into four equal-sized groups: first quartile (<6 ug/L), second quartile (6-9 ug/L), third quartile (9-13 ug/L), and fourth quartile (>13 ug/L). Demographic, biochemical, and dialysis-related data were obtained for analyses. A linear regression model was applied to identify factors associated with SAL. Cox proportional hazard model was used to determine the significance of variables in prediction of mortality. RESULTS: Only 9.3% of MHD patients had SALs of 20 ug/L or more. At the end of the follow-up, 54 patients (6%) died, and the main cause of death was cardiovascular disease. Kaplan-Meier survival analysis showed that patients in the fourth SAL quartile had higher mortality than those in the first SAL quartile (log rank test, chi2=13.47, P=0.004). Using the first quartile as reference, Cox multivariate analysis indicated that patients in the third quartile (hazard ratio =1.31, 95% confidence interval =1.12-1.53, P=0.038) and the fourth quartile (hazard ratio =3.19, 95% confidence interval =1.08-8.62, P=0.048) had increased risk of all-cause mortality. CONCLUSION: This study demonstrates that SAL, even when in an apparently acceptable range (below 20 ug/L), is associated with increased mortality in MHD patients. The findings suggest that avoiding exposure of aluminum as much as possible is warranted for MHD patients. PMID- 27695339 TI - A Comparison of Morphine Delivery in Neonatal Opioid Withdrawal. AB - Current estimates of the prevalence of opioid withdrawal in newborns from the 2012 Better Outcomes Registry and Network Ontario reveal that more than 4 births per 1000 display recognizable symptoms of neonatal abstinence syndrome (NAS). With a growing consensus surrounding aspects of newborn opioid withdrawal care, clinicians might agree that all infants exposed to maternal opioids require supportive observation and care to ensure appropriate adaptation and growth in the newborn period and, likewise, that there exists a smaller percentage of newborns who require additional pharmacotherapy. However, due to the dearth of comparative studies of NAS tools, there remains a lack of evidence to support the use of a specific NAS method of scoring or treatment. Two types of NAS treatment protocols currently in use include a symptom-only versus weight-based protocols. Our Neonatal Intensive Care Unit (NICU) has used both models. A formal structured NAS tool and weight-based morphine delivery system began in our NICU in 1999. We audited all newborns with known exposure to maternal opioids in our NICU from the years 2000 to 2014. The Finnegan scoring tool was used throughout all years of the chart audit. Modifications made to the Finnegan scoring tool from the MOTHER study were adapted for use in our NICU at the same time as adopting the Johns Hopkins model of symptom-only based morphine delivery in 2006. The objective of this comparative study using a retrospective chart audit is to compare length of stay (LOS) and total accumulative morphine dose across these two morphine delivery protocols. Our audit revealed that there were a significantly higher proportion of newborns in the symptom-only model that received morphine and, perhaps accordingly, also had a significantly higher LOS compared to those in the weight-based model. Comparing only those infants who did receive morphine, the comparative total accumulative dose of morphine and LOS were not significantly different between the weight-based and symptom-only morphine delivery models. PMID- 27695340 TI - Improving perioperative care for adolescent idiopathic scoliosis patients: the impact of a multidisciplinary care approach. AB - The complex nature of the surgical treatment of adolescent idiopathic scoliosis (AIS) requires a wide variety of health care providers. A well-coordinated, multidisciplinary team approach to the care of these patients is essential for providing high-quality care. This review offers an up-to-date overview of the numerous interventions and safety measures for improving outcomes after AIS surgery throughout the perioperative phases of care. Reducing the risk of potentially devastating and costly complications after AIS surgery is the responsibility of every single member of the health care team. Specifically, this review will focus on the perioperative measures for preventing surgical site infections, reducing the risk of neurologic injury, minimizing surgical blood loss, and preventing postoperative complications. Also, the review will highlight the postoperative protocols that emphasize early mobilization and accelerated discharge. PMID- 27695341 TI - Novel Approach to Analyzing MFE of Noncoding RNA Sequences. AB - Genomic studies have become noncoding RNA (ncRNA) centric after the study of different genomes provided enormous information on ncRNA over the past decades. The function of ncRNA is decided by its secondary structure, and across organisms, the secondary structure is more conserved than the sequence itself. In this study, the optimal secondary structure or the minimum free energy (MFE) structure of ncRNA was found based on the thermodynamic nearest neighbor model. MFE of over 2600 ncRNA sequences was analyzed in view of its signal properties. Mathematical models linking MFE to the signal properties were found for each of the four classes of ncRNA analyzed. MFE values computed with the proposed models were in concordance with those obtained with the standard web servers. A total of 95% of the sequences analyzed had deviation of MFE values within +/-15% relative to those obtained from standard web servers. PMID- 27695342 TI - Limb-salvage treatment of en-block resected distal femoral tumors with endoprosthesis of all-polyethylene tibial component: a 9-year follow-up study. AB - OBJECTIVE: To evaluate the medium-term outcome of limb-salvage surgery using all polyethylene tibial endoprosthetic replacement following en-block resection for distal femoral tumors. METHODS: Forty-nine patients with distal femoral tumor were treated between June 2006 and June 2012. The follow-up period was 6-110 months (average 53.4 months). The prosthetic survival was analyzed using the Kaplan-Meier method. The classification of failure of limb salvage after reconstructive surgery for bone tumors was adapted. Limb function was evaluated with the scoring system of the Musculoskeletal Tumor Society (MSTS). RESULTS: Complications were observed in six cases (12.2%). Four suffered infection around the prosthesis, of which two cases were treated with debridement, drainage, and antibiotics without removal of the prosthesis, and the other two cases underwent amputation. Two cases were identified as radiographically loose at 7 year follow up and did not require revision surgery. One patient underwent amputation due to local recurrence. Failure of limb salvage occurred in nine cases (18.4%), of which two cases were of type 1A, two cases of type 2B, three cases of type 4A, one case of type 4B, and one case of type 5A. The mean MSTS score was 84.3%. Twelve cases died due to distant metastases (24.5%), and the average survival time for these patients was 13.5 months. Thirty-seven patients survived (75.5%), for whom the average follow-up time was 66.3 months and the 5-year prosthetic survival rate was 88.2%. CONCLUSION: The outcome of medium-term and long-term clinical follow-up was satisfactory. All-polyethylene tibial endoprosthetic replacement following en-block resection can be an alternative method of limb salvage for distal femoral tumors. PMID- 27695343 TI - A retrospective study of neoadjuvant chemotherapy plus radical hysterectomy versus radical hysterectomy alone in patients with stage II cervical squamous cell carcinoma presenting as a bulky mass. AB - OBJECTIVE: In order to evaluate the usefulness of neoadjuvant chemotherapy (NAC) for stage II cervical squamous cell carcinoma with a bulky mass, we retrospectively compared patients receiving NAC followed by radical hysterectomy (RH; NAC group) with patients who underwent RH without NAC (Ope group). PATIENTS AND METHODS: The study period was from June 2002 to March 2014. The subjects were 28 patients with a stage II bulky mass in the NAC group and 17 such patients in the Ope group. The chi-square test was used to compare operative time, volume of intraoperative blood loss, use of blood transfusion, and time from surgery to discharge between the two groups. Moreover, the log-rank test using the Kaplan Meier method was performed to compare disease-free survival (DFS) and overall survival (OS) between the groups. RESULTS: There were no statistically significant differences between the two groups in operative time, volume of intraoperative blood loss, or use of blood transfusion. However, the time from surgery to discharge was 18 days (14-25 days) in the NAC group and 25 days (21-34 days) in the Ope group; the patients in the NAC group were discharged earlier (P=0.032). The hazard ratio for DFS in the NAC group as compared with that in the Ope group was 0.36 (95% CI 0.08-0.91), and the 3-year DFS rates were 81.2% and 41.0%, respectively (P=0.028). Moreover, the hazard ratio for OS was 0.39 (95% CI 0.11-1.24), and the 3-year OS rates were 82.3% and 66.4%, respectively (P=0.101). CONCLUSION: NAC with cisplatin and irinotecan was confirmed to prolong DFS as compared with RH alone. The results of this study suggest that NAC might be a useful adjunct to surgery in the treatment of stage II squamous cell carcinoma presenting as a bulky mass. PMID- 27695344 TI - Primary gastric anaplastic lymphoma kinase-negative anaplastic large-cell lymphoma. AB - INTRODUCTION: Most primary stomach lymphomas are now recognized to originate from B-cell. Primary gastric anaplastic lymphoma kinase (ALK)-negative anaplastic large-cell lymphoma (ALCL) as shown in this case is very rare. CASE REPORT: A 59 year-old man presented with a 1-month history of epigastric pain. Computed tomography showed a tumor in the stomach with perigastric lymphadenopathy. Biopsy of the tumor with gastroendoscopy showed ALCL. Bone marrow aspiration and trephine biopsy showed no infiltration. A diagnosis of primary gastric ALK negative ALCL was made. The patient was first treated with four cycles of cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) regimen, but his condition did not show improvement. Then he was treated with two cycles of hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone/methotrexate and cytarabine (Hyper-CVAD/MA) regimen. In spite of these treatments, he still died of disease progression. CONCLUSION: The prognosis of ALK-negative ALCLs is usually worse than ALK-positive ALCLs. In this case, the patient was not responsive to a multidrug chemotherapy with CHOP and Hyper CVAD/MA. PMID- 27695345 TI - Sonidegib, a novel smoothened inhibitor for the treatment of advanced basal cell carcinoma. AB - Basal cell carcinoma (BCC) is the most common nonmelanoma skin cancer. If left untreated, BCCs can become locally aggressive or even metastasize. Currently available treatments include local destruction, surgery, and radiation. Systemic options for advanced disease are limited. The Hedgehog (Hh) pathway is aberrantly activated in a majority of BCCs and in other cancers. Hh pathway inhibitors are targeted agents that inhibit the aberrant activation of the Hh pathway, with smoothened being a targeted component. Sonidegib is a novel smoothened inhibitor that was recently approved by the US Food and Drug Administration. This review focuses on BCC pathogenesis and the clinical efficacy of sonidegib for the treatment of advanced BCC. PMID- 27695346 TI - MicroRNA expression profiles predict progression and clinical outcome in lung adenocarcinoma. AB - Lung cancer is one of the leading causes of cancer death worldwide. Accumulating evidence has indicated that microRNAs (miRNAs) can be proposed as promising diagnostic and prognostic markers for various cancers. The current study analyzed the miRNA expression profiles of 418 lung adenocarcinoma (LUAD) cases obtained from The Cancer Genome Atlas dataset, with the aim to investigate the relationship of miRNAs with progression and prognosis of LUAD. A total of 185 miRNAs were found to be differentially expressed between LUAD tumor tissues and adjacent normal tissues. Among them, 13, 10, 0, and 10 miRNAs were discovered to be associated with pathologic T, N, M, and Stage, respectively. Interestingly, mir-200 family (mir-200a, mir-200b, and mir-429) was shown to play a critical role in the progression of LUAD. In the multivariate Cox regression analysis, mir 1468 (P=0.009), mir-212 (P=0.026), mir-3653 (P=0.012), and mir-31 (P=0.002) were significantly correlated with recurrence-free survival. With regard to overall survival, mir-551b (P=0.011), mir-3653 (P=0.016), and mir-31 (P=0.001) were proven as independent prognostic markers. In summary, this study identified the cancer-specific miRNAs that may predict the progression and prognosis of LUAD. PMID- 27695347 TI - Clinical comparative investigation of efficacy and toxicity of cisplatin plus gemcitabine or plus Abraxane as first-line chemotherapy for stage III/IV non small-cell lung cancer. AB - PURPOSE: The purpose of this study was to observe the clinical efficacy and toxicity of cisplatin in combination with gemcitabine or Abraxane as first-line chemotherapy for stage III/IV non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: A total of 200 patients with advanced NSCLC, which was confirmed by pathology or cytology, were enrolled into our research by reviewing previous complete and retrievable medical records data of our hospital. A total of 100 patients were treated with gemcitabine (1,000 mg/m2, day 1 and day 8) in combination with cisplatin (75 mg/m2, days 1-3; GP group) and another 100 patients were treated with Abraxane (260 mg/m2, day 1) in combination with cisplatin (75 mg/m2, days 1-3; TP group). Twenty-one days were required to complete one cycle; at least two cycles were completed by each group. RESULTS: For the 100 patients in the GP group, the effective response rate (RR) was 27%, the disease control rate (DCR) was 63%, and the median progression-free survival (PFS) time was 8 months. For the 100 patients in the TP group, the RR was 52%, the DCR was 75%, and the median PFS was 20 months. There was significant difference in RR (P<0.001), but no significant difference in DSR and PFS (P>0.05). Common treatment-related adverse events were hematologic toxicity and gastrointestinal reaction. Hematologic toxicity mainly included decreased white blood cells and platelets. The differences between the two groups were statistically significant (P<0.05). Gastrointestinal reaction mainly included nausea and vomiting. There was no statistical significance between them (P=0.805). For the 85 patients with squamous carcinoma in the TP group, the RR was 60%, the DCR was 78%, and the median PFS was 7.5 months. For the 85 patients with squamous carcinoma in the GP group, the RR was 36%, the DCR was 62%, and the median PFS was 18.5 months. There was significant difference in RR (P=0.024), but no significant difference in DSR and PFS (P>0.05). For the 115 patients with adenocarcinoma in the TP group, the RR was 47%, the DCR was 73%, and the median PFS was 8 months. For the 115 patients with adenocarcinoma in the GP group, the RR was 20%, the DCR was 64%, and the median PFS was 20.5 months. There was significant difference in RR (P=0.003), but no significant difference in DCR and PFS (P>0.05). CONCLUSION: The efficacy of cisplatin in combination with Abraxane is better than that with gemcitabine in the treatment of NSCLC, and the treatment has less risk of hematologic toxicity. PMID- 27695348 TI - A negative regulation loop of long noncoding RNA HOTAIR and p53 in non-small-cell lung cancer. AB - Non-small-cell lung cancer (NSCLC) is one of the leading causes of cancer-related death worldwide, and the 5-year survival rate is still low despite advances in diagnosis and therapeutics. A long noncoding RNA (lncRNA) HOX antisense intergenic RNA (HOTAIR) has been revealed to play important roles in NSCLC carcinogenesis but the detailed mechanisms are still unclear. In the current study, we aimed to investigate the regulation between the lncRNA HOTAIR and p53 in the NSCLC patient samples and cell lines. Our results showed that HOTAIR expression was significantly higher in the cancer tissues than that in the adjacent normal tissue, and was negatively correlated with p53 functionality rather than expression. When p53 was overexpressed in A549 cells, the lncRNA HOTAIR expression was downregulated, and the cell proliferation rate and cell invasion capacity decreased as a consequence. We identified two binding sites of p53 on the promoter region of HOTAIR, where the p53 protein would bind to and suppress the HOTAIR mRNA transcription. Inversely, overexpression of lncRNA HOTAIR inhibited the expression of p53 in A549 cells. Mechanistic studies revealed that HOTAIR modified the promoter of p53 and enhanced histone H3 lysine 27 trimethylation (H3K27me3). These studies identified a specific negative regulation loop of lncRNA HOTAIR and p53 in NSCLC cells, which revealed a new understanding of tumorigenesis in p53 dysfunction NSCLC cells. PMID- 27695349 TI - Proton beam therapy: clinical utility and current status in prostate cancer. AB - Proton beam therapy has recently become available to a broader population base. There remains much controversy about its routine use in prostate cancer. We provide an analysis of the existing literature regarding efficacy and toxicity of the technique. Currently, the use of proton beam therapy for prostate cancer is largely dependent on continued reimbursement for the practice. While there are potential benefits supporting the use of protons in prostate cancer, the low risk of toxicity using existing techniques and the high cost of protons contribute to lower the value of the technique. PMID- 27695350 TI - Study of the correlations between fractional exhaled nitric oxide in exhaled breath and atopic status, blood eosinophils, FCER2 mutation, and asthma control in Vietnamese children. AB - INTRODUCTION: Fractional exhaled nitric oxide (FENO) is a biomarker of airway inflammation in asthma. The measurement of FENO is utilized to assist in the diagnosis and treatment of children with asthma, especially for those treated with inhaled corticosteroids. OBJECTIVES: The aims of this study were to evaluate the correlations between FENO and atopic status, blood eosinophil levels, FCER2 mutation, and asthma control in Vietnamese children. SUBJECTS AND METHODS: This was a prospective and descriptive study approved by the local Ethical Board. All children with uncontrolled asthma, seen in the National Hospital of Pediatrics (Hanoi, Vietnam), were included. Exhaled breath FENO, blood eosinophils, skin prick test, total IgE, asthma control test (ACT), and FCER2 gene polymorphism were performed at inclusion. They were followed up at 3 months to evaluate clinical status, FENO levels, and ACT. RESULTS: Forty-two children with uncontrolled asthma with a mean age of 10+/-3 years (6-16 years) were included. The male/female ratio was 2.5/1. The mean FENO levels were 26+/-25 ppb. FENO was significantly higher in patients with a positive skin prick test for respiratory allergens (P<0.05). FENO was significantly correlated with blood eosinophil levels (r=0.5217; P=0.0004). Five of the 32 subjects (15.6%) had a mutation of FCER2 gene (rs28364072 SNP). In this group, the levels of FENO were highest (37+/ 10 ppb; P<0.05). The levels of FENO were significantly decreased after 3 months of treatment (17+/-8 ppb vs 26+/-25 ppb; P<0.05). Significant correlations between inhaled corticosteroid doses and FENO levels occurred at 1 and 3 months (r=0.415, P=0.007; r=0.396, P=0.010; respectively). There were no correlations between FENO levels, ACT, and daily use of salbutamol. After 3 months, asthma remained uncontrolled in 22.2% of children. CONCLUSION: The measurement of FENO levels is a useful and feasible tool to predict clinical, biological, and asthma control in Vietnamese children. PMID- 27695352 TI - Cost analysis of magnetically controlled growing rods compared with traditional growing rods for early-onset scoliosis in the US: an integrated health care delivery system perspective. AB - PURPOSE: Traditional growing rod (TGR) for early-onset scoliosis (EOS) is effective but requires repeated invasive surgical lengthenings under general anesthesia. Magnetically controlled growing rod (MCGR) is lengthened noninvasively using a hand-held magnetic external remote controller in a physician office; however, the MCGR implant is expensive, and the cumulative cost savings have not been well studied. We compared direct medical costs of MCGR and TGR for EOS from the US integrated health care delivery system perspective. We hypothesized that over time, the MCGR implant cost will be offset by eliminating repeated TGR surgical lengthenings. METHODS: For both TGR and MCGR, the economic model estimated the cumulative costs for initial implantation, lengthenings, revisions due to device failure, surgical-site infections, device exchanges (at 3.8 years), and final fusion, over a 6-year episode of care. Model parameters were estimated from published literature, a multicenter EOS database of US institutions, and interviews. Costs were discounted at 3.0% annually and represent 2015 US dollars. RESULTS: Of 1,000 simulated patients over 6 years, MCGR was associated with an estimated 270 fewer deep surgical-site infections and 197 fewer revisions due to device failure compared with TGR. MCGR was projected to cost an additional $61 per patient over the 6-year episode of care compared with TGR. Sensitivity analyses indicated that the results were sensitive to changes in the percentage of MCGR dual rod use, months between TGR lengthenings, percentage of hospital inpatient (vs outpatient) TGR lengthenings, and MCGR implant cost. CONCLUSION: Cost neutrality of MCGR to TGR was achieved over the 6 year episode of care by eliminating repeated TGR surgical lengthenings. To our knowledge, this is the first cost analysis comparing MCGR to TGR - from the US provider perspective - which demonstrates the efficient provision of care with MCGR. PMID- 27695351 TI - Lemierre's syndrome: current perspectives on diagnosis and management. AB - This is a systematic review of cases with Lemierre's syndrome (LS) in the past 5 years. LS is characterized by sepsis often evolving after a sore throat or tonsillitis and then complicated by various septic emboli and thrombosis of the internal jugular vein. Symptoms include sepsis, pain, and/or swelling in the throat or neck, as well as respiratory symptoms. Laboratory findings show elevated infectious parameters and radiological findings show thrombosis of the internal jugular vein and emboli in the lungs or other organs. The syndrome is often associated with an infection with Fusobacterium necrophorum. We found a total of 137 cases of LS, of which 47 were infected with F. necrophorum and others with Staphylococcus and Streptococcus. Complications of this rare but severe disease included osteomyelitis, meningitis, and acute respiratory distress syndrome. Mortality was extremely high in the pre-antibiotic era but has diminished with the advent of antibiotics. This review showed a mortality rate of only 2% of which none of the cases involved fusobacteria. Duration of treatment varied; a 4-6-week course of carbapenem or piperacillin/tazobactam in combination with metronidazole was optimum. Other treatment options included anticoagulants in 46% of cases, which is unwarrantedly high, as to date, no evidence of the positive effects of anticoagulants in LS exists. Only two cases had ligation of the internal jugular vein performed. This review confirms the rare, but severe aspects of LS. Mortality from LS in this day and age appears to be low, however the syndrome is difficult to recognize, and still requires the full attention of the clinician. PMID- 27695353 TI - Consequences of inaccurate hepatitis C virus genotyping on the costs of prescription of direct antiviral agents in an Italian district. AB - Available commercial assays may yield inaccurate hepatitis C virus (HCV) genotype assignment in up to 10% of cases. We investigated the cost-effectiveness of re evaluating HCV genotype by population sequencing, prior to choosing a direct acting antiviral (DAA) regimen. Between March and September 2015, HCV sequence analysis was performed in order to confirm commercial LiPA-HCV genotype (Versant(r) HCV Genotype 2.0) in patients eligible for treatment with DAAs. Out of 134 consecutive patients enrolled, sequencing yielded 21 (15.7%) cases of discordant results. For three cases of wrong genotype assignment, the putative reduction in efficacy was gauged between 15% and 40%. Among the eight cases for whom G1b was assigned by commercial assays instead of G1a, potentially suboptimal treatments would have been prescribed. Finally, for five patients with G1 and indeterminate subtype, the choice of regimens would have targeted the worst option, with a remarkable increase in costs, as in the case of the four mixed HCV infections for whom pan-genotypic regimens would have been mandatory. Precise assignment of HCV genotype and subtype by sequencing may, therefore, be more beneficial than expected, until more potent pan-genotypic regimens are available for all patients. PMID- 27695354 TI - Management of familial benign chronic pemphigus. AB - Benign familial chronic pemphigus or Hailey-Hailey disease is caused by an autosomal dominant mutation in the ATP2C1 gene leading to suprabasilar acantholysis. The disease most commonly affects intertriginous areas symmetrically. The chronic nature of the disease and multiple recurrences make the disease bothersome for patients and a treatment challenge for physicians. Treatments include topical and/or systemic agents and surgery including laser. This review summarizes the available treatment options. PMID- 27695355 TI - Influence of Saccharomyces boulardii CNCM I-745on the gut-associated immune system. AB - BACKGROUND: The probiotic Saccharomyces boulardii CNCM I-745 (also known as Saccharomyces cerevisiae HANSEN CBS 5926; in the following S. boulardii) has proven its effectiveness in preventive and therapeutic treatment of many gastrointestinal diseases, especially diseases associated with acute diarrhea. In particular, antibiotic-associated diarrhea, Clostridium difficile-associated diarrhea, traveller's diarrhea, as well as acute diarrhea due to common viral and bacterial infections in children and adults. AIM: The aim of this review is to summarize the experimental studies elucidating the molecular and immunological mechanisms by which these clinically proven effects are archived, with an emphasis on the gut-associated immune system. The main focus is laid on anti inflammatory and immune-modulatory action of S. boulardii involved in bacterial or enterotoxin-mediated diarrhea and inflammation. An attempt is made to differentiate between the effects associated with cellular versus soluble factors and between prophylactic and therapeutic effects. METHODS: A literature search was performed in PubMed/PubMed Central for the effects of S. boulardii on the gut associated immune system (focus acute diarrhea). RESULTS AND CONCLUSION: S. boulardii exhibits its positive effect by the direct effects on pathogens or their toxins as well as by influencing the host's infection-induced signaling cascades and its innate and adaptive immune system. The combination of these mechanisms results in a reduction of the pathogens' ability for adhesion or colonization and an attenuation of the overreacting inflammatory immune response. Thereby, the integrity of the intestinal epithelial cell layer is preserved or restored, and the diarrheic leakage of fluids into the intestinal lumen is attenuated. PMID- 27695358 TI - The correlation between CYP2D6 isoenzyme activity and haloperidol efficacy and safety profile in patients with alcohol addiction during the exacerbation of the addiction. AB - BACKGROUND: Today, it is proved that isoenzymes CYP2D6 and CYP3A4 are involved in metabolism of haloperidol. In our previous investigation, we found a medium correlation between the efficacy and safety of haloperidol and the activity of CYP3A4 in patients with alcohol abuse. OBJECTIVE: The aim of this study was to evaluate the correlation between the activity of CYP2D6 and the efficacy and safety of haloperidol in patients with diagnosed alcohol abuse. METHODS: The study involved 70 men (average age: 40.83+/-9.92 years) with alcohol addiction. A series of psychometric scales were used in the research. The activity of CYP2D6 was evaluated by high-performance liquid chromatography with mass spectrometry using the ratio of 6-hydroxy-1,2,3,4-tetrahydro-beta-carboline to pinoline. Genotyping of CYP2D6 (1846G>A) was performed using real-time polymerase chain reaction. RESULTS: According to results of correlation analysis, statistically significant values of Spearman correlation coefficient (rs) between the activity of CYP2D6 and the difference of points in psychometric scale were obtained in patients receiving haloperidol in injection form (Sheehan Clinical Anxiety Rating Scale =-0.721 [P<0.001] and Udvald for Kliniske Undersogelser Side Effect Rating Scale =0.692 [P<0.001]) and in those receiving haloperidol in tablet form (Covi Anxiety Scale =-0.851 [P<0.001] and Udvald for Kliniske Undersogelser Side Effect Rating Scale =0.797 [P<0.001]). CONCLUSION: This study demonstrated the correlations between the activity of CYP2D6 isozyme and the efficacy and safety of haloperidol in patients with alcohol addiction.

AB - The prevalence of HIV-associated chronic kidney disease (CKD) varies geographically and depends on the definition of CKD used, ranging from 4.7% to 38% globally. The incidence, however, has decreased with the use of effective combined antiretroviral therapy (cART). A wide variety of histological patterns are seen in HIV-associated kidney diseases that include glomerular and tubulointerstitial pathology. In resource-rich settings, there has been a plateau in the incidence of end-stage renal disease secondary to HIV-associated nephropathy (HIVAN). However, the prevalence of end-stage renal disease in HIV positive individuals has risen, mainly due to increased longevity on cART. There is a disparity in the occurrence of HIVAN among HIV-positive individuals such that there is an 18- to 50-fold increased risk of developing kidney disease among HIV-positive individuals of African descent aged between 20 and 64 years and who have a poorer prognosis compared with their European descent counterparts, suggesting that genetic factors play a vital role. Other risk factors include male sex, low CD4 counts, and high viral load. Improvement in renal function has been observed after initiation of cART in patients with HIV-associated CKD. Treatment with an angiotensin-converting enzyme inhibitor/angiotensin receptor blocker is recommended, when clinically indicated in patients with confirmed or suspected HIVAN or clinically significant albuminuria. Other standard management approaches for patients with CKD are recommended. These include addressing other cardiovascular risk factors (appropriate use of statins and aspirin, weight loss, cessation of smoking), avoidance of nephrotoxins, and management of serum bicarbonate and uric acid, anemia, calcium, and phosphate abnormalities. Early diagnosis of kidney disease by screening of HIV-positive individuals for the presence of kidney disease is critical for the optimal management of these patients. Screening for the presence of kidney disease upon detection of HIV infection and annually thereafter in high-risk populations is recommended. PMID- 27695356 TI - Managing eosinophilic esophagitis: challenges and solutions. AB - Eosinophilic esophagitis (EoE) is a chronic and progressive immune-mediated condition defined by symptoms of esophageal dysfunction and dense eosinophilic infiltration of the esophageal mucosa. Therapies consist of anti-eosinophilic medications and specialized diets aimed to decrease the progression of EoE and alleviate its symptoms, namely, dysphagia and food impaction. Assessing response to therapy remains challenging, as treatment end points are not well defined and currently consist of clinical, histologic, and endoscopic features. Newer validated measures may help standardize treatment end points. Emerging data support the use of maintenance therapy, which may reduce disease progression. Optimal dosages, delivery techniques, and duration of treatment need to be determined. When features of fibrostenosis develop, esophageal dilation is a safe and effective adjunctive strategy for improving symptoms. In EoE cases refractory to conventional treatments, newer therapies targeting inflammatory mediators and cytokines are on the horizon. PMID- 27695359 TI - Parecoxib increases muscle pain threshold and relieves shoulder pain after gynecologic laparoscopy: a randomized controlled trial. AB - OBJECTIVES: Postlaparoscopic shoulder pain (PLSP) remains a common problem after laparoscopies. The aim of this study was to investigate the correlation between pressure pain threshold (PPT) of different muscles and PLSP after gynecologic laparoscopy, and to explore the effect of parecoxib, a cyclooxygenase-2 inhibitor, on the changes of PPT. MATERIALS AND METHODS: The patients were randomly allocated into two groups; group P and group C. In group P, parecoxib 40 mg was intravenously infused at 30 minutes before surgery and 8 and 20 hours after surgery. In group C, normal saline was infused at the corresponding time point. PPT assessment was performed 1 day before surgery and at postoperative 24 hours by using a pressure algometer at bilateral shoulder muscles (levator scapulae and supraspinatus) and forearm (flexor carpi ulnaris). Meanwhile, bilateral shoulder pain was evaluated through visual analog scale score at 24 hours after surgery. RESULTS: Preoperative PPT level of the shoulder, but not of the forearm, was significantly and negatively correlated with the intensity of ipsilateral PLSP. In group C, PPT levels of shoulder muscles, but not of forearm muscles, decreased after laparoscopy at postoperative 24 hours. The use of parecoxib significantly improved the decline of PPT levels of bilateral shoulder muscles (all P<0.01). Meanwhile, parecoxib reduced the incidence of PLSP (group P: 45% vs group C: 83.3%; odds ratio: 0.164; 95% confidence interval: 0.07-0.382; P<0.001) and the intensity of bilateral shoulder pain (both P<0.01). CONCLUSION: Preoperative PPT levels of shoulder muscles are closely associated with the severity of shoulder pain after gynecologic laparoscopy. PPT levels of shoulder muscles, but not of forearm muscles, significantly decreased after surgery. Parecoxib improved the decrease of PPT and relieved PLSP. PMID- 27695360 TI - Translation, adaptation, and validation of the behavioral pain scale and the critical-care pain observational tools in Taiwan. AB - This study describes the cultural adaptation and testing of the behavioral pain scale (BPS) and the critical-care pain observation tools (CPOT) for pain assessment in Taiwan. The cross-cultural adaptation followed the steps of translation, including forward translation, back-translation, evaluation of the translations by a committee of experts, adjustments, and then piloting of the prefinal versions of the BPS and the CPOT. A content validity index was used to assess content validities of the BPS and the CPOT, with 0.80 preset as the level that would be regarded as acceptable. The principal investigator then made adjustments when the content validity index was <0.80. The pilot test was performed with a sample of ten purposively selected patients by 2 medical staff from a medical care center in Taiwan. The BPS and the CPOT are adequate instruments for the assessment of pain levels in patients who cannot communicate due to sedation and ventilation treatments. PMID- 27695362 TI - Reduction of central neuropathic pain with ketamine infusion in a patient with Ehlers-Danlos syndrome: a case report. AB - OBJECTIVE: Ehlers-Danlos syndrome frequently causes acute and chronic pain because of joint subluxations and dislocations secondary to hypermobility. Current treatments for pain related to Ehlers-Danlos syndrome and central pain syndrome are inadequate. This case report discusses the therapeutic use of ketamine intravenous infusion as an alternative. CASE REPORT: A 27-year-old Caucasian female with a history of Ehlers-Danlos syndrome and spinal cord ischemic myelopathy resulting in central pain syndrome, presented with severe generalized body pain refractory to multiple pharmacological interventions. After a 7-day course of ketamine intravenous infusion under controlled generalized sedation in the intensive care unit, the patient reported a dramatic reduction in pain levels from 7-8 out of 10 to 0-3 out of 10 on a numeric rating scale and had a significant functional improvement. The patient tolerated a reduction in her pain medication regimen, which originally included opioids, gabapentin, pregabalin, tricyclic antidepressants, and nonsteroidal anti-inflammatory drugs. CONCLUSION: Ketamine infusion treatment has been used in various pain syndromes, including central neuropathic pain, ischemic pain, and regional pain syndrome. Reports have suggested that ketamine modulates pain by the regression of N-methyl D-aspartate receptor to a resting state. As such, propagation of nociceptive signal to brain is interrupted allowing for the restoration of physiological balance between pain inhibition and facilitation. The present report shows that this treatment option can be used in patients with refractory central pain syndrome in the setting of spinal cord myelopathy secondary to Ehlers-Danlos syndrome. In addition, as seen in this case, this protocol can potentially decrease the chronic use of pain medication, such as opioids. PMID- 27695361 TI - Detection of central circuits implicated in the formation of novel pain memories. AB - Being able to remember physically and emotionally painful events in one's own past may shape behavior, and can create an aversion to a variety of situations. Pain imagination is a related process that may include recall of past experiences, in addition to production of sensory and emotional percepts without external stimuli. This study aimed to understand 1) the central nervous system processes that underlie pain imagination, 2) the retrieval of pain memories, and 3) to compare the latter with visual object memory. These goals were achieved by longitudinally investigating brain function with functional magnetic resonance imaging in a unique group of healthy volunteers who had never experienced tooth pain. In these subjects, we compared brain responses elicited during three experimental conditions in the following order: imagination of tooth pain (pain imagination), remembering one's own house (object memory), and remembrance of tooth pain following an episode of induced acute tooth pain (pain memory). Key observations stemming from group-level conjunction analyses revealed common activation in the posterior parietal cortex for both pain imagination and pain memory, while object and pain memory each had strong activation predominantly within the middle frontal gyrus. When contrasting pain imagination and memory, significant activation differences were observed in subcortical structures (ie, parahippocampus - pain imagination > pain memory; midbrain - pain memory > pain imagination). Importantly, these findings were observed in the presence of consistent and reproducible psychophysical and behavioral measures that informed on the subjects' ability to imagine novel and familiar thoughts, as well as the subjects' pain perception. PMID- 27695364 TI - Health service use among children with and without eczema, asthma, and hay fever. AB - BACKGROUND: Atopic diseases, for example, eczema, asthma, and hay fever, are among the most common chronic diseases of childhood. Knowledge on health service use among children with atopic disease is limited. This study aimed to investigate the total use and costs of health services for children with and without eczema, asthma, and hay fever in a Danish general population. METHODS: We conducted a health survey with four complete birth cohorts from the City of Copenhagen. Individual questionnaire data on eczema, asthma, and hay fever for children aged 3, 6, 11, and 15 years were linked to register information on use and costs of health services and prescribed medication and parental education. In total 9,720 children participated (50.5%). RESULTS: We found increased health service use (number of additional consultations per year [95% confidence interval]) among children with current eczema symptoms (1.77 [1.29-2.26]), current asthma symptoms (2.53 [2.08-2.98]), and current hay fever symptoms (1.21 [0.74-1.67]), compared with children without these symptoms. We also found increased use of prescribed medication and most subtypes of health services. Current asthma symptoms and current eczema symptoms, but not current hay fever symptoms, increased the health service costs with at least ?300 per year per child. CONCLUSION: Children with eczema, asthma, and hay fever used health services and prescribed medication more than children without these diseases. PMID- 27695365 TI - Continuation rates, bleeding profile acceptability, and satisfaction of women using an oral contraceptive pill containing estradiol valerate and dienogest versus a progestogen-only pill after switching from an ethinylestradiol containing pill in a real-life setting: results of the CONTENT study. AB - BACKGROUND: Oral contraceptives are still associated with high discontinuation rates, despite their efficacy. There is a wide choice of oral contraceptives available, and the aim of this study was to assess continuation rates, bleeding profile acceptability, and the satisfaction of women in the first year of using a contraceptive pill containing estradiol valerate and dienogest (E2V/DNG) versus a progestogen-only pill (POP) in a real-life setting after discontinuing an ethinylestradiol-containing pill. METHODS AND RESULTS: In this prospective, noninterventional, observational study, 3,152 patients were included for the efficacy analyses (n=2,558 women in the E2V/DNG group and n=592 in the POP group (two patients fulfilled the criteria of the efficacy population, but the used product was not known). Women had been taking an ethinylestradiol-containing pill >=3 months before deciding to switch to the E2V/DNG pill or a POP. Overall, 19.8% (n=506) of E2V/DNG users and 25.8% (n=153) of POP users discontinued their prescribed pill. The median time to discontinuation was 157.0 days and 127.5 days, respectively. Time to discontinuation due to bleeding (P<0.0001) or other reasons (P=0.022) was significantly longer in the E2V/DNG group versus the POP group. The E2V/DNG pill was also associated with shorter (48.7% vs 44.1%), lighter (54% vs 46.1%), and less painful bleeding (91.1% vs 73.7%) and greater user satisfaction (80.7% vs 64.6%) than POP use, within 3-5 months after switch. CONCLUSION: The E2V/DNG pill was associated with higher rates of continuation, bleeding profile acceptability, and user satisfaction than POP use and may be an alternative option for women who are dissatisfied with their current pill. PMID- 27695363 TI - Atypical teratoid/rhabdoid tumors: challenges and search for solutions. AB - Atypical teratoid/rhabdoid tumor (AT/RT) is a highly malignant embryonal central nervous system tumor commonly affecting children <3 years of age. It roughly constitutes 1%-2% of all pediatric central nervous system tumors. Recent data show that it is the most common malignant central nervous system tumor in children <6 months of age. Management of this aggressive tumor is associated with a myriad of diagnostic and therapeutic challenges. On the basis of radiology and histopathology alone, distinction of AT/RT from medulloblastoma or primitive neuroectodermal tumor is difficult, and hence this tumor has been commonly misdiagnosed as primitive neuroectodermal tumor for decades. Presence of a bulky heterogeneous solid-cystic mass with readily visible calcification and intratumor hemorrhage, occurring off-midline in children <3 years of age, should alert the radiologist toward the possibility of AT/RT. Presence of rhabdoid cells on histopathology and polyphenotypic immunopositivity for epithelial, mesenchymal, and neuroectodermal markers along with loss of expression of SMARCB1/INI1 or SMARCA4/BRG1 help in establishing a diagnosis of AT/RT. The optimal management comprises maximal safe resection followed by radiation therapy and multiagent intensive systemic chemotherapy. Gross total excision is difficult to achieve in view of the large tumor size and location and young age at presentation. Leptomeningeal spread is noted in 15%-30% of patients, and hence craniospinal irradiation followed by boost to tumor bed is considered standard in children older than 3 years. However, in younger children, craniospinal irradiation may lead to long-term neurocognitive and neuroendocrine sequel, and hence focal radiation therapy may be a pragmatic approach. In this age group, high-dose chemotherapy with autologous stem cell rescue may also be considered to defer radiation therapy, but this approach is also associated with significant treatment-related morbidity and mortality. Novel small molecule inhibitors hold promise in preclinical studies and should be considered in patients with relapsed or refractory tumor. PMID- 27695366 TI - Primary dysmenorrhea magnitude, associated risk factors, and its effect on academic performance: evidence from female university students in Ethiopia. AB - BACKGROUND: Primary dysmenorrhea (PD) is the most common gynecologic compliant among adolescent females. There is a wide variation in the estimate of PD, which ranges from 50% to 90%, and the disorder is the most common cause of work and school absenteeism in adolescent females. OBJECTIVE: To assess the prevalence and associated risk factors of PD among female university students and understand its effects on students' academic performance. METHODS: A cross-sectional study was employed in 440 research participants. A multistage stratified sampling technique was employed to select the study units. Structured and pretested self administered questionnaires were used and weight and height measurements were conducted. The severity of dysmenorrheal pain was assessed by using a verbal multidimensional scoring system and visual analog scale. The data were double entered in Epi Info version 3.1 and analyzed using SPSS version 17. Descriptive statistics, chi-square test, and logistic regression analysis were performed. RESULTS: A total of 440 students participated in this study. The prevalence of PD was 368 (85.4%). Of these, 123 (28.5%) had mild, 164 (38.1%) moderate, and 81 (18.8%) severe primary dysmenorrheal pain. Among students with PD, 88.3% reported that PD had a negative effect on their academic performance. Of these, 80% reported school absence, 66.8% reported loss of class concentration, 56.3% reported class absence, 47.4% reported loss of class participation, 37.8% reported limited sport participation, 31.7% reported limitation in going out with friends, and 21% reported inability to do homework. Based on the multivariate logistic regression, PD was statistically significant with those who had lower monthly stipends, a history of attempt to lose weight, a history of depression or anxiety, disruption of social network of family, friends or people they love, who consumed more than four glasses of tea per day, who drunk one or more Coca-Cola or Pepsi per day, in nullipara, and students with a family history of dysmenorrhea. CONCLUSION: PD is more prevalent among female students attending university. It has a significant negative impact on students' academic performance. Thus, it needs medical attention. There are various identified associated risk factors and considering them in the management of the disorder is fundamental. It is also wise to recommend future studies to better identify risk factors for PD and lighten its effect on students' academic performance at a larger scale in the country. PMID- 27695367 TI - Simultaneous occlusion of three cilioretinal arteries following scleral buckling surgery under local anesthesia. AB - BACKGROUND: Cilioretinal artery (CRA) occlusions are rare in young patients. In these cases, the most commonly associated causes are considered to be the same as those implicated in central retina artery occlusions, such as vasculitic processes, migraine, cardiac disorder, and coagulation abnormality. The aim of this article was to report for the first time the medical records and investigational results of an unusual case of simultaneous occlusion of three CRAs after scleral buckling surgery under local anesthesia. METHODS: A complete ophthalmic examination, including color fundus image, fundus fluorescein angiography, optical coherence tomography, visual field, as well as systemic and laboratory assessments, was performed. RESULTS: A case of contemporaneous blockage of three CRAs after ab externo surgery for retinal detachment in a 29 year-old Caucasian woman was reported. The interdisciplinary approach and the imaging results have allowed us the clinical definition of such a very rare case. CONCLUSION: Here, we reported that optical coherence tomography is an indispensable tool to better delineate the pathological process and follow atrophic changes in the macula, especially in cases in which fundus fluorescein angiography and systemic tests may be poorly informative. PMID- 27695368 TI - Progressive loss of vision caused by asymptomatic pituitary macroadenoma: role of OCT. AB - INTRODUCTION: Most pituitary adenomas are clinically inactive. In patients with long-standing compression of the optic chiasm, ganglion cells may undergo axonal degeneration. Spectral domain optical coherence tomography (SD-OCT) is able to identify retinal nerve fiber layer (RNFL) and ganglion cell loss in the retina. We present a case in which SD-OCT was used to diagnose an asymptomatic pituitary macroadenoma. CLINICAL CASE: A 48-year-old female presented with progressive vision loss in both eyes. SD-OCT identified atrophy of the ganglion cell and nerve layers, with preservation of outer layers bilaterally. Magnetic resonance imaging of the brain showed a pituitary macroadenoma. The pathological diagnosis was nonfunctioning adenoma. DISCUSSION: As macroadenomas enlarge, they can induce uncrossed axon loss, resulting in nasal field defects and reduced visual acuity. In these cases, there is atrophy of the nasal and temporal portions of the optic disc, thus occupying a horizontal band across the disc. SD-OCT is able to identify RNFL loss in eyes with band atrophy of the optic nerve, which correlates with visual field defects found in perimetry. SD-OCT is a useful tool to assess the structural and functional damage of ganglion cells. In our case the SD-OCT demonstrated a symmetrical loss of the RNFL and the ganglion cell layer in both eyes, indicating important optic nerve damage. PMID- 27695369 TI - A simple, wide bandwidth, biopotential amplifier to record pacemaker pulse waveform. AB - Reliable detection of pacemaker pulses is getting more and more important in electrocardiography (ECG) diagnosis. Many studies recommend ECG amplifiers with higher bandwidth to prevent errors. In the past, few pilot studies showed that analysis of pacemaker pulses waveform can enhance diagnosis (eg, lead failure and fractured wire), but they were carried out with inadequate instrumentations for clinical practice. Typically, pacemaker pulses last hundreds of microseconds, edges of pulses elapse in few microseconds, and amplitude may exhibit large variations from few millivolts to volts. Pulse waveforms change often and depend on pacemaker type and programming. A simple, biopotential amplifier made of a few off-the-shelf components is proposed. The circuit fulfills specifications for biopotential amplifiers and offers a large bandwidth (~1 MHz). Therefore, it is able to accurately record time course of pacemaker pulses and allows highly accurate pulse detection and timing. Signals can be easily displayed and acquired by means of a standard, battery-powered oscilloscope. Pacemaker pulse vectorcardiography can be obtained by using two or more, wideband channels. Some exemplificative waveforms recorded during patient's periodic medical examination are reported. The proposed circuit offers simultaneous conventional ECG signal as an additional output. PMID- 27695370 TI - Presence and consequence of tooth periapical radiolucency in patients with cirrhosis. AB - BACKGROUND: Periapical radiolucency is the radiographic sign of inflammatory bone lesions around the apex of the tooth. We determined the prevalence and predictors of periapical radiolucency in patients with cirrhosis and the association with systemic inflammation status and cirrhosis-related complications. METHODS: A total of 110 cirrhosis patients were consecutively enrolled. Periapical radiolucency was defined as the presence of radiolucency or widening of the periapical periodontal ligament space to more than twice the normal width. Predictors of periapical radiolucency and the association with systemic inflammation markers and cirrhosis-related complications were explored by univariable and multivariable logistic regression analyses. RESULTS: Periapical radiolucency was present in one or more teeth in 46% of the patients. Strong predictors were gross caries (odds ratio [OR] 3.12, 95% confidence interval [CI] 1.43-6.79) and severe periodontitis (OR 3.98, 95% CI 1.04-15.20). Also old age (OR 1.10, 95% CI 1.01-1.19) and smoking (OR 3.24, 95% CI 1.02-17.62) were predictors. However, cirrhosis etiology (alcoholic vs nonalcoholic) or severity (Model of End-Stage Liver Disease score) were not predictors. The patients with periapical radiolucency had higher C-reactive protein (15.8 mg/L vs 8.1 mg/L, P=0.02) and lower albumin contents (25 g/L vs 28 g/L, P=0.04) than those without. Furthermore, the patients with periapical radiolucency had a higher prevalence of cirrhosis-related complications such as ascites, hepatic encephalopathy, and/or variceal bleeding (46% vs 27%, P=0.05). CONCLUSION: Periapical radiolucency is often present as an element of poor oral health status and likely has an adverse clinical significance, which should motivate diagnostic and clinical attention to the findings. PMID- 27695371 TI - Effects of gamma irradiation on the biomechanical properties of peroneus tendons. AB - PURPOSE: This study was designed to investigate the biomechanical properties of nonirradiated (NI) and irradiated (IR) peroneus tendons to determine if they would be suitable allografts, in regards to biomechanical properties, for anterior cruciate ligament reconstruction after a dose of 1.5-2.5 Mrad. METHODS: Seven pairs of peroneus longus (PL) and ten pairs of peroneus brevis (PB) tendons were procured from human cadavers. The diameter of each allograft was measured. The left side of each allograft was IR at 1.5-2.5 Mrad, whereas the right side was kept aseptic and NI. The allografts were thawed, kept wet with saline, and attached in a single-strand fashion to custom freeze grips using liquid nitrogen. A preload of 10 N was then applied and, after it had reached steady state, the allografts were pulled at 4 cm/sec. The parameters recorded were the displacement and force. RESULTS: The elongation at the peak load was 10.3+/-2.3 mm for the PB NI side and 13.5+/-3.3 mm for the PB IR side. The elongation at the peak load was 17.4+/-5.3 mm for the PL NI side and 16.3+/-2.0 mm for the PL IR side. For PL, the ultimate load was 2,091.6+/-148.7 N for NI and 2,122.8+/-380.0 N for IR. The ultimate load for the PB tendons was 1,485.7+/-209.3 N for NI and 1,318.4+/-296.9 N for the IR group. The ultimate stress calculations for PL were 90.3+/-11.3 MPa for NI and 94.8+/-21.0 MPa for IR. For the PB, the ultimate stress was 82.4+/ 19.0 MPa for NI and 72.5+/-16.6 MPa for the IR group. The structural stiffness was 216.1+/-59.0 N/mm for the NI PL and 195.7+/-51.4 N/mm for the IR side. None of these measures were significantly different between the NI and IR groups. The structural stiffness was 232.1+/-45.7 N/mm for the NI PB and 161.9+/-74.0 N/mm for the IR side, and this was the only statistically significant difference found in this study (P=0.034). CONCLUSION: Our statistical comparisons found no significant differences in terms of elongation, ultimate load, or ultimate stress between IR and NI PB and PL tendons. Only the PB structural stiffness was affected by irradiation. Thus, sterilizing allografts at 1.5-2.5 Mrad of gamma irradiation does not cause major alterations in the tendons' biomechanical properties while still providing a suitable amount of sterilization for anterior cruciate ligament reconstruction. PMID- 27695372 TI - The impact of shift work on the psychological and physical health of nurses in a general hospital: a comparison between rotating night shifts and day shifts. AB - BACKGROUND: Shift work is considered necessary to ensure continuity of care in hospitals and residential facilities. In particular, the night shift is one of the most frequent reasons for the disruption of circadian rhythms, causing significant alterations of sleep and biological functions that can affect physical and psychological well-being and negatively impact work performance. OBJECTIVES: The aim of this study was to highlight if shift work with nights, as compared with day work only, is associated with risk factors predisposing nurses to poorer health conditions and lower job satisfaction. METHODS: This cross sectional study was conducted from June 1, 2015 to July 31, 2015 in 17 wards of a general hospital and a residential facility of a northern Italian city. This study involved 213 nurses working in rotating night shifts and 65 in day shifts. The instrument used for data collection was the "Standard Shift Work Index," validated in Italian. Data were statistically analyzed. RESULTS: The response rate was 86%. The nurses engaged in rotating night shifts were statistically significantly younger, more frequently single, and had Bachelors and Masters degrees in nursing. They reported the lowest mean score in the items of job satisfaction, quality and quantity of sleep, with more frequent chronic fatigue, psychological, and cardiovascular symptoms in comparison with the day shift workers, in a statistically significant way. CONCLUSION: Our results suggest that nurses with rotating night schedule need special attention due to the higher risk for both job dissatisfaction and undesirable health effects. PMID- 27695374 TI - Waterpipe Tobacco Smoking Among Dental Practitioners: Prevalence and Health Perceptions. AB - BACKGROUND: Waterpipe tobacco smoking prevalence, practice, and the associated health perceptions among dental practitioners have not been previously reported. This study aims to determine the prevalence of waterpipe smoking among dental practitioners and to evaluate their awareness of health hazards of waterpipe smoking, particularly the adverse effects on oral health. METHODS: This was a cross-sectional questionnaire-based survey among dental practitioners. Surveyed dental practitioners practiced dentistry in the holy city of Al-Madinah Al Munawarah, a city in the Central-Western Region of Saudi Arabia, and the study was conducted during March 2015. The questionnaire consisted of questions on demographic data, history and practices of tobacco use, and perceptions toward the health hazards of smoking. Dentists were approached at their work places and invited to participate. Descriptive statistics were used to describe the sample's demographic and smoking characteristics, while cross-tabulation and chi-square test were used to determine the statistical significance of association between the groups (P <= 0.05). RESULTS: One hundred dental practitioners participated in the survey, with 55 males and 45 females. Twenty-six percent indicated that they were waterpipe smokers. Male gender and cigarette smoking were the only factors to be significantly associated with waterpipe smoking (P = 0.008 and P = 0.000, respectively). Most participants stated that waterpipe smoking is harmful to health, and the most commonly reported health hazard was respiratory disease, which was reported by 81% of participants. CONCLUSIONS: Prevalence of waterpipe smoking among dental practitioners is comparable to adult populations but lower than younger populations of university students. Health awareness of dental practitioners regarding waterpipe smoking was judged to be insufficient. PMID- 27695373 TI - Police custody health care: a review of health morbidity, models of care and innovations within police custody in the UK, with international comparisons. AB - This paper is a scoping review of the available evidence regarding health care issues in police custody. It describes the types and prevalence of health disorders encountered in custody and provides an overview of current practice and recent innovations in police custody health care. In contrast to the health of prisoners, the health of police custody detainees has, until recently, received little academic or clinical attention. Studies on health care in police custody identified for this review are limited to a few geographical jurisdictions, including the UK, continental Europe, North America, and Australia. There are significant health concerns among police detainees including acute injury, chronic physical health problems, mental and cognitive disorders, and the risks associated with drug and alcohol intoxication or withdrawal. There is some evidence that deaths in police custody have reduced where attention has been paid to the latter issue. Police personnel continue to experience difficulties identifying detainees with health issues relevant to their safe detention, but research shows that the use of evidence-based screening tools improves detection of such morbidities. Innovations in police custody health care mainly relate to detainees with mental disorders, including improved identification of illness, timely access to mental health services, the protection of the rights of mentally disordered detainees, and the diversion of mentally disordered persons from the criminal justice system into appropriate health and social care interventions. There is a lack of rigorous research relating to interventions for physical health problems, protecting those at risk of substance withdrawal, and detainees with preexisting or peri-arrest injures. Research to improve the health of police custody detainees requires greater priority, focusing on case identification and service redesign to address high levels of morbidity and to facilitate health promotion and prevention activities. PMID- 27695376 TI - Distress prior to undergoing hematopoietic stem cell transplantation: demographic and symptom correlations and establishing a baseline. AB - BACKGROUND: Distress can arise from physical and/or psychosocial impairments and has been documented in patients after hematopoietic stem cell transplantation in the outpatient setting. It has not been evaluated in inpatients admitted to undergo the transplant, nor has potential correlations with length of hospital stay, physical function, and pain after receiving the transplant. OBJECTIVES: To measure distress in patients admitted to the hospital to undergo hematopoietic stem cell transplantation, and to evaluate potential correlations with length of hospital stay, physical function, pain, and depression/anxiety. METHODS: Eighty patients were given a questionnaire to report levels of distress and physical and psychosocial functioning. Hierarchical multiple regression analysis was used to test the relationship of demographic and transplant factors with length of stay (LOS), distress, presence of pain, and depression/anxiety. RESULTS: Patients reported pretransplant distress with an average score of 2.2 out of 10, and 16 out of 80 patients reported clinically relevant distress. Pain was reported by 42.5% of patients, and 28.8% reported depression/anxiety. Physical functioning was generally high. Distress was correlated with depression/anxiety (P-value <0.01) and pain (0.04) but not with LOS, physical function, patient age, or transplant type. CONCLUSION: LOS after receiving stem cell transplant was not related to pretransplant distress. Distress exists pretransplant but is generally low. Pain and the presence of depression/anxiety may be risk factors for distress. Measuring distress prior to transplant gives a baseline from which to measure changes, potentially leading to earlier intervention. PMID- 27695375 TI - Epigenetics and Cellular Metabolism. AB - Living eukaryotic systems evolve delicate cellular mechanisms for responding to various environmental signals. Among them, epigenetic machinery (DNA methylation, histone modifications, microRNAs, etc.) is the hub in transducing external stimuli into transcriptional response. Emerging evidence reveals the concept that epigenetic signatures are essential for the proper maintenance of cellular metabolism. On the other hand, the metabolite, a main environmental input, can also influence the processing of epigenetic memory. Here, we summarize the recent research progress in the epigenetic regulation of cellular metabolism and discuss how the dysfunction of epigenetic machineries influences the development of metabolic disorders such as diabetes and obesity; then, we focus on discussing the notion that manipulating metabolites, the fuel of cell metabolism, can function as a strategy for interfering epigenetic machinery and its related disease progression as well. PMID- 27695377 TI - Therapeutic and routine prophylactic properties of rFactor VIII Fc (efraloctocog alfa, Eloctate(r)) in hemophilia A. AB - rFVIIIFc (efraloctocog alfa, Eloctate(r)) is an extended half-life (EHL) factor VIII licensed for use in patients with hemophilia A for prophylaxis and treatment of bleeding and surgical episodes. Pharmacokinetic studies in adults have shown a mean 1.5-fold increase in half-life compared to full-length factor VIII. When compared to adults, the half-life is decreased by 8% in adolescents between 12 and 17 years, by 18% in children 6 to <12 years, and by 33% in children between the ages of 2 and <6 years. There is a considerable interindividual variation in the prolongation of the half-life particularly in children and across the age groups, the range extending from no increase to a 2.5-fold increase. In addition to age, von willebrand factor (VWF) antigen level has demonstrated a significant impact on rFVIIIFc half-life, with higher VWF levels associated with greater prolongation of half-life. The pivotal and pediatric clinical trials have demonstrated the efficacy and safety of rFVIIIFc for use in regular prophylaxis and in management of bleeds and surgery. In these studies, just under half the participants showed a zero annualized bleed rate (ABR), and the median ABR (1.6 in the pivotal study for the individualized prophylaxis arm) showed a further decrease in the extension study. On average, the patients required fewer infusions (reduced by at least a third), and the mean weekly consumption seems to be in keeping with standard recombinant factor VIII. EHL rFVIIIFc has made decreased infusion frequency a possibility. However, the interindividual variability in dose and infusion frequency highlights the need for a personalized approach based on individual patient's half-life and/or response to treatment. PMID- 27695378 TI - Improving self-regulation in adolescents: current evidence for the role of mindfulness-based cognitive therapy. AB - Mindfulness-based cognitive therapy (MBCT) was introduced in 1995 to address the problem of recurrent depression. MBCT is based on the notion that meditation helps individuals effectively deploy and regulate attention to effectively manage and treat a range of psychological symptoms, including emotional responses to stress, anxiety, and depression. Several studies demonstrate that mindfulness approaches can effectively reduce negative emotional reactions that result from and/or exacerbate psychiatric difficulties and exposure to stressors among children, adolescents, and their parents. Mindfulness may be particularly relevant for youth with maladaptive cognitive processes such as rumination. Clinical experience regarding the utility of mindfulness-based approaches, including MBCT, is being increasingly supported by empirical studies to optimize the effective treatment of youth with a range of challenging symptoms. This paper provides a description of MBCT, including mindfulness practices, theoretical mechanisms of action, and targeted review of studies in adolescents. PMID- 27695379 TI - Hyperglycemia: A Predictor of Death in Severe Head Injury Patients. AB - OBJECTIVES: Management of hyperglycemia during an acute sickness in adults is accompanied by improved outcomes. We have designed a prospective study with meticulous attention to exclude all diabetes patients by checking hemoglobin A1c (HbA1c or glycated hemoglobin) to avoid the ill-effects of hyperglycemia in patients with traumatic head injury admitted to the intensive care unit (ICU). METHODS: This prospective study included adults with traumatic primary brain injury with a Glasgow coma score of <=8 necessitating mechanical ventilation treated in the period 2012-2015. After screening 311 patients, 220 were included in the study. Both blood glucose and HbA1c levels of all the patients at admission, as well as blood glucose level after 72 hours, were obtained from the records. The patients were later grouped based on their admission blood glucose levels (<200 mg/dL or >=200 mg/dL). Injury severity score (ISS) was documented for every patient. As a final point, the outcomes were determined based on the hospital length of stay (HLS) and ICU length of stay (ILS), plusmortality rates. RESULTS: About 39% (n = 85) of patients were admitted with hyperglycemia during the study period. The mortality rate in patients with glucose >=200 mg/dL was 65.8% (N = 56), against 23.7% (N = 32) in the group with glucose <200 mg/dL, with mortality rising as the blood glucose level increased (P = 0.014). CONCLUSIONS: We conclude that admission hyperglycemia is related with increased mortality rate in head injury patients, and comprehensive treatment of hyperglycemia can improve the outcome of severe head injury patients.

AB - Clinical rotations form the foundation of medical education. Medical students in the UK are offered conventional rotations such as cardiology, surgery, and psychiatry as part of their undergraduate curriculum, but a rotation in hematology is not currently mandatory. This paper explores the benefits of a compulsory hematology rotation, and suggests recommendations for its implementation in UK medical school curricula. PMID- 27695382 TI - Factors associated with opioid overdose: a 10-year retrospective study of patients in a large integrated health care system. AB - OBJECTIVE: Opioid overdoses (ODs) have been increasing, and harm reduction efforts are a priority. The success of these efforts will be dependent on the identification of at-risk patients and improved access to the antidote naloxone. Therefore, to identify access to naloxone and factors associated with negative health outcomes, we conducted a retrospective study of patients with OD to identify those at highest risk of adverse outcomes and to assess the use of naloxone. METHODS: We conducted a study of electronic health records for patients admitted to the largest multihospital system in the region - the Geisinger Health System (GHS) for ODs - from April 2005 through March 2015. ODs were defined by International Classification of Diseases-9 codes (age range: 10-95 years). Bivariate analyses and multiple logistic regressions were conducted to identify pre-OD factors associated with adverse health outcomes post-OD. RESULTS: We identified 2,039 patients with one or more ODs, of whom 9.4% were deceased within 12 months. Patient demographics suggest that patients with OD had a mean age of 52 years, were not married (64%), and were unemployed (78%). Common comorbidities among patients with OD include cardiovascular disease (22%), diabetes (14%), cancer (13%), and the presence of one or more mental health disorders (35%). Few patients had a prescription order for naloxone (9%) after their OD. The majority of patients with OD were in proximity to GHS health care facilities, with 87% having a GHS primary care provider. In multiple logistic regressions, common predictors of adverse outcomes, including death, repeated ODs, frequent service use, and high service cost, were higher prescription opioid use, comorbid medical conditions, comorbid mental disorders, and concurrent use of other psychotropic medications. CONCLUSION: This study suggests opportunities for improving OD outcomes. Those who receive higher quantities of prescription opioids concurrent with other psychotropic medicines may need closer monitoring to avoid death, repeated OD events, higher service use, and higher service costs. Other opportunities for improving OD outcomes include the use of electronic health records to notify physicians of high-risk patients and updating of guidelines/operation manuals focused on the distribution of naloxone to those in highest need. PMID- 27695383 TI - Resampling-based multiple comparison procedure with application to point-wise testing with functional data. AB - In this paper we describe a coherent multiple testing procedure for correlated test statistics such as are encountered in functional linear models. The procedure makes use of two different p-value combination methods: the Fisher combination method and the Sidak correction-based method. P-values for Fisher's and Sidak's test statistics are estimated through resampling to cope with the correlated tests. Building upon these two existing combination methods, we propose the smallest p-value as a new test statistic for each hypothesis. The closure principle is incorporated along with the new test statistic to obtain the overall p-value and appropriately adjust the individual p-values. Furthermore, a shortcut version for the proposed procedure is detailed, so that individual adjustments can be obtained even for a large number of tests. The motivation for developing the procedure comes from a problem of point-wise inference with smooth functional data where tests at neighboring points are related. A simulation study verifies that the methodology performs well in this setting. We illustrate the proposed method with data from a study on the aerial detection of the spectral effect of below ground carbon dioxide leakage on vegetation stress via spectral responses. PMID- 27695384 TI - Movement analysis of free-grazing domestic ducks in Poyang Lake, China: a disease connection. AB - Previous work suggests domestic poultry are important contributors to the emergence and transmission of highly pathogenic avian influenza throughout Asia. In Poyang Lake, China, domestic duck production cycles are synchronized with arrival and departure of thousands of migratory wild birds in the area. During these periods, high densities of juvenile domestic ducks are in close proximity to migratory wild ducks, increasing the potential for the virus to be transmitted and subsequently disseminated via migration. In this paper, we use GPS dataloggers and dynamic Brownian bridge models to describe movements and habitat use of free-grazing domestic ducks in the Poyang Lake basin and identify specific areas that may have the highest risk of H5N1 transmission between domestic and wild birds. Specifically, we determine relative use by free-grazing domestic ducks of natural wetlands, which are the most heavily used areas by migratory wild ducks, and of rice paddies, which provide habitat for resident wild ducks and lower densities of migratory wild ducks. To our knowledge, this is the first movement study on domestic ducks, and our data show potential for free-grazing domestic ducks from farms located near natural wetlands to come in contact with wild waterfowl, thereby increasing the risk for disease transmission. This study provides an example of the importance of movement ecology studies in understanding dynamics such as disease transmission on a complicated landscape. PMID- 27695386 TI - Developing attributes for discrete choice experiments in health: a systematic literature review and case study of alcohol misuse interventions. AB - Discrete choice experiments (DCEs) become increasingly popular to value outcomes for health economic studies and gradually gain acceptance as an input into policy decisions. Developing attributes is a key aspect for the design of DCEs, as their results may misguide decision-makers if they are based on an inappropriate set of attributes. However, the area lacks guidance, and current health-related DCE studies vary considerably in their methods of attribute development, with the consequent danger of providing an unreliable input for policy decisions. The aim of this article is to inform the progress toward a more systematic approach to attribute development for DCE studies in health. A systematic review of the published health-related DCE literature was conducted to lay the foundations for a generic framework which was tested in a case study of alcohol misuse interventions. Four stages of a general attribute development process emerged: (i) raw data collection; (ii) data reduction; (iii) removing inappropriate attributes; and (iv) wording. The case study compared and contrasted a qualitative and mixed-methods approach for the development of attributes for DCEs in the area of alcohol misuse interventions. This article provides a reference point for the design of future DCE experiments in health. PMID- 27695387 TI - Parental smoking and children's anxieties: An appropriate strategy for health education? AB - While the prevalence of smoking has declined in the UK in recent years, class differentials in smoking behaviour have become more marked and smoking is increasingly recognised as a causal factor in inequalities in health. Health education initiatives to support both smoking cessation and to teach children about the health risks of smoking remain key initiatives in reducing health inequalities. However, teaching children about the risks of smoking and the impact of parental smoking in their health is not straightforward for children from backgrounds who are more likely to encounter smoking at home and in their local communities. These children have to reconcile the key messages taught at school and reinforced in smoking cessation campaigns with the knowledge that their parents and other family members smoke. In this paper we consider how children from smoking homes make sense of these education and health campaigns as observed by their parents, and the impact that this has on both parental smoking and relationships within the home. The paper thus seeks to challenge assumptions about the delivery of health education and the need to acknowledge family diversity. PMID- 27695388 TI - Exploring stories of occupational engagement in a regional secure unit. AB - This paper focuses on the occupational experiences of five men living within a forensic mental health unit over a year. This study used a descriptive qualitative case study methodology to explore the meaning and value placed on daily life (activities, occupations and routines), and how this changed over time. The men's stories showed a complex picture of their experiences of daily life. This study demonstrated the impact of the environment on the men and the ongoing challenge of the need to balance treatment/therapy with security demands and opportunities. Three interrelated themes were identified: (1) Power and Occupation; (2) Therapy or Punishment; (3) Occupational Opportunities within Restrictions. These findings serve as a reminder to clinical teams to reassess the value of occupations attributed by their patients and the impact of the secure environment, whilst also acknowledging the potential for occupations to have a negative impact on well-being. PMID- 27695385 TI - The Functional Overlap of Executive Control and Language Processing in Bilinguals. AB - The need to control multiple languages is thought to require domain-general executive control (EC) in bilinguals such that the EC and language systems become interdependent. However, there has been no systematic investigation into how and where EC and language processes overlap in the bilingual brain. If the concurrent recruitment of EC during bilingual language processing is domain-general and extends to non-linguistic EC, we hypothesize that regions commonly involvement in language processing, linguistic EC, and non-linguistic EC may be selectively altered in bilinguals compared to monolinguals. A conjunction of functional magnetic resonance imaging (fMRI) data from a flanker task with linguistic and nonlinguistic distractors and a semantic categorization task showed functional overlap in the left inferior frontal gyrus (LIFG) in bilinguals, whereas no overlap occurred in monolinguals. This research therefore identifies a neural locus of functional overlap of language and EC in the bilingual brain. PMID- 27695389 TI - Stable Isotopes Suggest Low Site Fidelity in Bar-headed Geese (Anser indicus) in Mongolia: Implications for Disease Transmission. AB - Population connectivity is an important consideration in studies of disease transmission and biological conservation, especially with regard to migratory species. Determining how and when different subpopulations intermingle during different phases of the annual cycle can help identify important geographical regions or features as targets for conservation efforts and can help inform our understanding of continental-scale disease transmission. In this study, stable isotopes of hydrogen and carbon in contour feathers were used to assess the degree of molt-site fidelity among Bar-headed Geese (Anser indicus) captured in north-central Mongolia. Samples were collected from actively molting Bar-headed Geese (n = 61), and some individual samples included both a newly grown feather (still in sheath) and an old, worn feather from the bird's previous molt (n = 21). Although there was no difference in mean hydrogen isotope ratios for the old and new feathers, the isotopic variance in old feathers was approximately three times higher than that of the new feathers, which suggests that these birds use different and geographically distant molting locations from year to year. To further test this conclusion, online data and modeling tools from the isoMAP website were used to generate probability landscapes for the origin of each feather. Likely molting locations were much more widespread for old feathers than for new feathers, which supports the prospect of low molt-site fidelity. This finding indicates that population connectivity would be greater than expected based on data from a single annual cycle, and that disease spread can be rapid even in areas like Mongolia where Bar-headed Geese generally breed in small isolated groups. PMID- 27695390 TI - Using Phenomic Analysis of Photosynthetic Function for Abiotic Stress Response Gene Discovery. AB - Monitoring the photosynthetic performance of plants is a major key to understanding how plants adapt to their growth conditions. Stress tolerance traits have a high genetic complexity as plants are constantly, and unavoidably, exposed to numerous stress factors, which limits their growth rates in the natural environment. Arabidopsis thaliana, with its broad genetic diversity and wide climatic range, has been shown to successfully adapt to stressful conditions to ensure the completion of its life cycle. As a result, A. thaliana has become a robust and renowned plant model system for studying natural variation and conducting gene discovery studies. Genome wide association studies (GWAS) in restructured populations combining natural and recombinant lines is a particularly effective way to identify the genetic basis of complex traits. As most abiotic stresses affect photosynthetic activity, chlorophyll fluorescence measurements are a potential phenotyping technique for monitoring plant performance under stress conditions. This review focuses on the use of chlorophyll fluorescence as a tool to study genetic variation underlying the stress tolerance responses to abiotic stress in A. thaliana. PMID- 27695391 TI - Latent Class Analysis of Incomplete Data via an Entropy-Based Criterion. AB - Latent class analysis is used to group categorical data into classes via a probability model. Model selection criteria then judge how well the model fits the data. When addressing incomplete data, the current methodology restricts the imputation to a single, pre-specified number of classes. We seek to develop an entropy-based model selection criterion that does not restrict the imputation to one number of clusters. Simulations show the new criterion performing well against the current standards of AIC and BIC, while a family studies application demonstrates how the criterion provides more detailed and useful results than AIC and BIC. PMID- 27695393 TI - The Reliability of Naturalistic Observations of Social, Physical and Economic Environments of Bars. AB - Drinking in bars contributes to numerous public health problems, including violence and motor vehicle crashes. In order to formulate effective preventive interventions it is essential to identify which specific features of bar environments are related to increased risks. Unobtrusive ethnographic observations are one approach that has been used to characterize these features; however no studies have assessed reliability in a representative sample of bars. We performed brief scouting assessments in all 165 bars in six purposively selected California cities, followed by unobtrusive observations from a subsequent representative sample of 97 bars which were located in low and high bar density areas of the cities. Inter-rater reliability between two independent observers assessed individual item reliability, and principal components analyses assessed the reliability of a series of scales describing the physical, social, and economic characteristics of the bars. For the scouting assessment, items exhibited at least moderate reliability (kappa or r >= 0.40). For the unobtrusive observations, items assessing physical and economic environments (e.g., pool table present, kappa = 0.90; index beer cost, r = 0.82) had moderate to outstanding reliability (kappa or r > 0.80). Items describing the social environment generally had poorer reliability, though group aspects (e.g., patron count, r = 0.78; patron circulation, r = 0.64) had better reliability than individual behaviors (e.g., derogatory speech, kappa = 0.12). Scales constructed from specific sets of items exhibited modest reliability. The individual metrics and principal components we present will enable future studies seeking to disaggregate relationships between bar characteristics and public health problems.

PMID- 27695394 TI - Risk factors for complications after pharyngolaryngectomy with total esophagectomy. AB - BACKGROUND: Pharyngolaryngectomy with total esophagectomy (PLTE) is an effective surgical treatment for synchronous or metachronous hypopharyngeal or laryngeal cancer and thoracic esophageal cancer, although it is more invasive than esophagectomy and total pharyngolaryngectomy. The aim of this study was to identify risk factors for complications after PLTE. METHODS: From November 2002 to December 2014, a total of 8 patients underwent PLTE at the Shizuoka Cancer Center Hospital, Shizuoka, Japan. We investigated the clinicopathological characteristics, surgical procedures, and postoperative complications of these patients. RESULTS: Of the 8 patients, 5 underwent one-stage PLTE and 3 underwent staged PLTE. There was no mortality in this study. Two cases of tracheal necrosis, two of anastomotic leakage, and one of ileus were observed as postoperative complications. Two patients who underwent one-stage PLTE with standard mediastinal lymph node dissection developed tracheal necrosis and severe anastomotic leakage. CONCLUSION: One-stage PLTE and standard mediastinal lymph node dissection were identified as the risk factors for severe postoperative complications. Staged PLTE or transhiatal esophagectomy should be considered when PLTE is performed and standard mediastinal lymph node dissection should be avoided when one-stage PLTE is performed with transthoracic esophagectomy. PMID- 27695395 TI - Coordination Dynamics in Cognitive Neuroscience. AB - Many researchers and clinicians in cognitive neuroscience hold to a modular view of cognitive function in which the cerebral cortex operates by the activation of areas with circumscribed elementary cognitive functions. Yet an ongoing paradigm shift to a dynamic network perspective is underway. This new viewpoint treats cortical function as arising from the coordination dynamics within and between cortical regions. Cortical coordination dynamics arises due to the unidirectional influences imposed on a cortical area by inputs from other areas that project to it, combined with the projection reciprocity that characterizes cortical connectivity and gives rise to reentrant processing. As a result, cortical dynamics exhibits both segregative and integrative tendencies and gives rise to both cooperative and competitive relations within and between cortical areas that are hypothesized to underlie the emergence of cognition in brains. PMID- 27695396 TI - Vascular Dysfunction in a Transgenic Model of Alzheimer's Disease: Effects of CB1R and CB2R Cannabinoid Agonists. AB - There is evidence of altered vascular function, including cerebrovascular, in Alzheimer's disease (AD) and transgenic models of the disease. Indeed vasoconstrictor responses are increased, while vasodilation is reduced in both conditions. beta-Amyloid (Abeta) appears to be responsible, at least in part, of alterations in vascular function. Cannabinoids, neuroprotective and anti inflammatory agents, induce vasodilation both in vivo and in vitro. We have demonstrated a beneficial effect of cannabinoids in models of AD by preventing glial activation. In this work we have studied the effects of these compounds on vessel density in amyloid precursor protein (APP) transgenic mice, line 2576, and on altered vascular responses in aortae isolated ring. First we showed increased collagen IV positive vessels in AD brain compared to control subjects, with a similar increase in TgAPP mice, which was normalized by prolonged oral treatment with the CB1/CB2 mixed agonist WIN 55,212-2 (WIN) and the CB2 selective agonist JWH-133 (JWH). In Tg APP mice the vasoconstriction induced by phenylephrine and the thromboxane agonist U46619 was significantly increased, and no change in the vasodilation to acetylcholine (ACh) was observed. Tg APP displayed decreased vasodilation to both cannabinoid agonists, which were able to prevent decreased ACh relaxation in the presence of Abeta. In summary, we have confirmed and extended the existence of altered vascular responses in Tg APP mice. Moreover, our results suggest that treatment with cannabinoids may ameliorate the vascular responses in AD-type pathology. PMID- 27695397 TI - A Personalized Multi-Channel FES Controller Based on Muscle Synergies to Support Gait Rehabilitation after Stroke. AB - It has been largely suggested in neuroscience literature that to generate a vast variety of movements, the Central Nervous System (CNS) recruits a reduced set of coordinated patterns of muscle activities, defined as muscle synergies. Recent neurophysiological studies have recommended the analysis of muscle synergies to finely assess the patient's impairment, to design personalized interventions based on the specific nature of the impairment, and to evaluate the treatment outcomes. In this scope, the aim of this study was to design a personalized multi channel functional electrical stimulation (FES) controller for gait training, integrating three novel aspects: (1) the FES strategy was based on healthy muscle synergies in order to mimic the neural solutions adopted by the CNS to generate locomotion; (2) the FES strategy was personalized according to an initial locomotion assessment of the patient and was designed to specifically activate the impaired biomechanical functions; (3) the FES strategy was mapped accurately on the altered gait kinematics providing a maximal synchronization between patient's volitional gait and stimulation patterns. The novel intervention was tested on two chronic stroke patients. They underwent a 4-week intervention consisting of 30-min sessions of FES-supported treadmill walking three times per week. The two patients were characterized by a mild gait disability (walking speed > 0.8 m/s) at baseline. However, before treatment both patients presented only three independent muscle synergies during locomotion, resembling two different gait abnormalities. After treatment, the number of extracted synergies became four and they increased their resemblance with the physiological muscle synergies, which indicated a general improvement in muscle coordination. The originally merged synergies seemed to regain their distinct role in locomotion control. The treatment benefits were more evident for one patient, who achieved a clinically important change in dynamic balance (Mini-Best Test increased from 17 to 22) coupled with a very positive perceived treatment effect (GRC = 4). The treatment had started the neuro-motor relearning process also on the second subject, but twelve sessions were not enough to achieve clinically relevant improvements. This attempt to apply the novel theories of neuroscience research in stroke rehabilitation has provided promising results, and deserves to be further investigated in a larger clinical study. PMID- 27695398 TI - Integrative Signaling Networks of Membrane Guanylate Cyclases: Biochemistry and Physiology. AB - This monograph presents a historical perspective of cornerstone developments on the biochemistry and physiology of mammalian membrane guanylate cyclases (MGCs), highlighting contributions made by the authors and their collaborators. Upon resolution of early contentious studies, cyclic GMP emerged alongside cyclic AMP, as an important intracellular second messenger for hormonal signaling. However, the two signaling pathways differ in significant ways. In the cyclic AMP pathway, hormone binding to a G protein coupled receptor leads to stimulation or inhibition of an adenylate cyclase, whereas the cyclic GMP pathway dispenses with intermediaries; hormone binds to an MGC to affect its activity. Although the cyclic GMP pathway is direct, it is by no means simple. The modular design of the molecule incorporates regulation by ATP binding and phosphorylation. MGCs can form complexes with Ca2+-sensing subunits that either increase or decrease cyclic GMP synthesis, depending on subunit identity. In some systems, co-expression of two Ca2+ sensors, GCAP1 and S100B with ROS-GC1 confers bimodal signaling marked by increases in cyclic GMP synthesis when intracellular Ca2+ concentration rises or falls. Some MGCs monitor or are modulated by carbon dioxide via its conversion to bicarbonate. One MGC even functions as a thermosensor as well as a chemosensor; activity reaches a maximum with a mild drop in temperature. The complexity afforded by these multiple limbs of operation enables MGC networks to perform transductions traditionally reserved for G protein coupled receptors and Transient Receptor Potential (TRP) ion channels and to serve a diverse array of functions, including control over cardiac vasculature, smooth muscle relaxation, blood pressure regulation, cellular growth, sensory transductions, neural plasticity and memory. PMID- 27695401 TI - Differences in the Flexibility of Switching Learning Strategies and CREB Phosphorylation Levels in Prefrontal Cortex, Dorsal Striatum and Hippocampus in Two Inbred Strains of Mice. AB - Flexibility in using different learning strategies was assessed in two different inbred strains of mice, the C57BL/6 and DBA/2 strains. Mice were trained sequentially in two different Morris water maze protocols that tested their ability to switch their learning strategy to complete a new task after first being trained in a different task. Training consisted either of visible platform trials (cued training) followed by subsequent hidden platform trials (place training) or the reverse sequence (place training followed by cued training). Both strains of mice showed equivalent performance in the type of training (cued or place) that they received first. However, C57BL/6 mice showed significantly better performances than DBA/2 mice following the switch in training protocols, irrespective of the order of training. After completion of the switched training session, levels of cAMP response element-binding protein (CREB) and phosphorylated CREB (pCREB) were measured in the hippocampus, striatum and prefrontal cortex of the mice. Prefrontal cortical and hippocampal pCREB levels differed by strain, with higher levels found in C57BL/6 mice than in DBA/2 mice. No strain differences were observed in the medial or lateral region of the dorsal striatum. These findings indicate that the engagement (i.e., CREB signaling) of relevant neural structures may vary by the specific demands of the learning strategy, and this is closely tied to differences in the flexibility of C57BL/6 and DBA/2 mice to switch their learning strategies when given a new task. PMID- 27695399 TI - NF-kappaB Pathways in the Pathogenesis of Multiple Sclerosis and the Therapeutic Implications. AB - Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) signaling pathways are involved in cell immune responses, apoptosis and infections. In multiple sclerosis (MS), NF-kappaB pathways are changed, leading to increased levels of NF-kappaB activation in cells. This may indicate a key role for NF-kappaB in MS pathogenesis. NF-kappaB signaling is complex, with many elements involved in its activation and regulation. Interestingly, current MS treatments are found to be directly or indirectly linked to NF-kappaB pathways and act to adjust the innate and adaptive immune system in patients. In this review, we will first focus on the intricacies of NF-kappaB signaling, including the activating pathways and regulatory elements. Next, we will theorize about the role of NF-kappaB in MS pathogenesis, based on current research findings, and discuss some of the associated therapeutic implications. Lastly, we will review four new MS treatments which interrupt NF-kappaB pathways-fingolimod, teriflunomide, dimethyl fumarate (DMF) and laquinimod (LAQ)-and explain their mechanisms, and the possible strategy for MS treatments in the future. PMID- 27695402 TI - Normal Evoked Response to Rapid Sequences of Tactile Pulses in Autism Spectrum Disorders. AB - Autism spectrum disorder (ASD) is a developmental disorder diagnosed behaviorally, with many documented neurophysiological abnormalities in cortical response properties. While abnormal sensory processing is not considered core to the disorder, most ASD individuals report sensory processing abnormalities. Yet, the neurophysiological correlates of these abnormalities have not been fully mapped. In the auditory domain, studies have shown that cortical responses in the early auditory cortex in ASD are abnormal in multiple ways. In particular, it has been shown that individuals with ASD have abnormal cortical auditory evoked responses to rapid, but not slow, sequences of tones. In parallel, there is substantial evidence of somatosensory processing abnormalities in ASD, including in the temporal domain. Here, we tested the somatosensory domain in ASD for abnormalities in rapid processing of tactile pulses, to determine whether abnormalities there parallel those observed in the auditory domain. Specifically, we tested the somatosensory cortex response to a sequence of two tactile pulses with different (short and long) temporal separation. We analyzed the responses in cortical space, in primary somatosensory cortex. As expected, we found no group difference in the evoked response to pulses with long (700 ms) temporal separation. Contrary to findings in the auditory domain, we also found no group differences in the evoked responses to the sequence with a short (200 ms) temporal separation. These results suggest that rapid temporal processing deficits in ASD are not generalized across multiple sensory domains, and are unlikely to underlie the behavioral somatosensory abnormalities observed in ASD. PMID- 27695403 TI - Novel Methods to Enhance Precision and Reliability in Muscle Synergy Identification during Walking. AB - Muscle synergies are hypothesized to reflect modular control of muscle groups via descending commands sent through multiple neural pathways. Recently, the number of synergies has been reported as a functionally relevant indicator of motor control complexity in individuals with neurological movement disorders. Yet the number of synergies extracted during a given activity, e.g., gait, varies within and across studies, even for unimpaired individuals. With no standardized methods for precise determination, this variability remains unexplained making comparisons across studies and cohorts difficult. Here, we utilize k-means clustering and intra-class and between-level correlation coefficients to precisely discriminate reliable from unreliable synergies. Electromyography (EMG) was recorded bilaterally from eight leg muscles during treadmill walking at self selected speed. Muscle synergies were extracted from 20 consecutive gait cycles using non-negative matrix factorization. We demonstrate that the number of synergies is highly dependent on the threshold when using the variance accounted for by reconstructed EMG. Beyond use of threshold, our method utilized a quantitative metric to reliably identify four or five synergies underpinning walking in unimpaired adults and revealed synergies having poor reproducibility that should not be considered as true synergies. We show that robust and unreliable synergies emerge similarly, emphasizing the need for careful analysis in those with pathology. PMID- 27695404 TI - Brain-Computer Interface Training after Stroke Affects Patterns of Brain-Behavior Relationships in Corticospinal Motor Fibers. AB - Background: Brain-computer interface (BCI) devices are being investigated for their application in stroke rehabilitation, but little is known about how structural changes in the motor system relate to behavioral measures with the use of these systems. Objective: This study examined relationships among diffusion tensor imaging (DTI)-derived metrics and with behavioral changes in stroke patients with and without BCI training. Methods: Stroke patients (n = 19) with upper extremity motor impairment were assessed using Stroke Impact Scale (SIS), Action Research Arm Test (ARAT), Nine-Hole Peg Test (9-HPT), and DTI scans. Ten subjects completed four assessments over a control period during which no training was administered. Seventeen subjects, including eight who completed the control period, completed four assessments over an experimental period during which subjects received interventional BCI training. Fractional anisotropy (FA) values were extracted from each corticospinal tract (CST) and transcallosal motor fibers for each scan. Results: No significant group by time interactions were identified at the group level in DTI or behavioral measures. During the control period, increases in contralesional CST FA and in asymmetric FA (aFA) correlated with poorer scores on SIS and 9-HPT. During the experimental period (with BCI training), increases in contralesional CST FA were correlated with improvements in 9-HPT while increases in aFA correlated with improvements in ARAT but with worsening 9-HPT performance; changes in transcallosal motor fibers positively correlated with those in the contralesional CST. All correlations p < 0.05 corrected. Conclusion: These findings suggest that the integrity of the contralesional CST may be used to track individual behavioral changes observed with BCI training after stroke. PMID- 27695406 TI - Digit Position and Forces Covary during Anticipatory Control of Whole-Hand Manipulation. AB - Theoretical perspectives on anticipatory planning of object manipulation have traditionally been informed by studies that have investigated kinematics (hand shaping and digit position) and kinetics (forces) in isolation. This poses limitations on our understanding of the integration of such domains, which have recently been shown to be strongly interdependent. Specifically, recent studies revealed strong covariation of digit position and load force during the loading phase of two-digit grasping. Here, we determined whether such digit force position covariation is a general feature of grasping. We investigated the coordination of digit position and forces during five-digit whole-hand manipulation of an object with a variable mass distribution. Subjects were instructed to prevent object roll during the lift. As found in precision grasping, there was strong trial-to-trial covariation of digit position and force. This suggests that the natural variation of digit position that is compensated for by trial-to-trial variation in digit forces is a fundamental feature of grasp control, and not only specific to precision grasp. However, a main difference with precision grasping was that modulation of digit position to the object's mass distribution was driven predominantly by the thumb, with little to no modulation of finger position. Modulation of thumb position rather than fingers is likely due to its greater range of motion and therefore adaptability to object properties. Our results underscore the flexibility of the central nervous system in implementing a range of solutions along the digit force-to position continuum for dexterous manipulation. PMID- 27695400 TI - Precision Medicine in Multiple Sclerosis: Future of PET Imaging of Inflammation and Reactive Astrocytes. AB - Non-invasive molecular imaging techniques can enhance diagnosis to achieve successful treatment, as well as reveal underlying pathogenic mechanisms in disorders such as multiple sclerosis (MS). The cooperation of advanced multimodal imaging techniques and increased knowledge of the MS disease mechanism allows both monitoring of neuronal network and therapeutic outcome as well as the tools to discover novel therapeutic targets. Diverse imaging modalities provide reliable diagnostic and prognostic platforms to better achieve precision medicine. Traditionally, magnetic resonance imaging (MRI) has been considered the golden standard in MS research and diagnosis. However, positron emission tomography (PET) imaging can provide functional information of molecular biology in detail even prior to anatomic changes, allowing close follow up of disease progression and treatment response. The recent findings support three major neuroinflammation components in MS: astrogliosis, cytokine elevation, and significant changes in specific proteins, which offer a great variety of specific targets for imaging purposes. Regardless of the fact that imaging of astrocyte function is still a young field and in need for development of suitable imaging ligands, recent studies have shown that inflammation and astrocyte activation are related to progression of MS. MS is a complex disease, which requires understanding of disease mechanisms for successful treatment. PET is a precise non-invasive imaging method for biochemical functions and has potential to enhance early and accurate diagnosis for precision therapy of MS. In this review we focus on modulation of different receptor systems and inflammatory aspect of MS, especially on activation of glial cells, and summarize the recent findings of PET imaging in MS and present the most potent targets for new biomarkers with the main focus on experimental MS research. PMID- 27695405 TI - Structural Imaging Changes and Behavioral Correlates in Patients with Crohn's Disease in Remission. AB - Background: Crohn's disease (CD) is a subtype of inflammatory bowel disease caused by immune-mediated inflammation in the gastrointestinal tract. The extent of morphologic brain alterations and their associated cognitive and affective impairments remain poorly characterized. Aims: We used magnetic resonance imaging to identify structural brain differences between patients with Crohn's disease in remission compared to age-matched healthy controls and evaluated for structural behavioral correlates. Methods: Nineteen patients and 20 healthy, age-matched controls were recruited in the study. Group differences in brain morphometric measures and correlations between brain measures and performance on a cognitive task, the verbal fluency (VF) task, were examined. Correlations between brain measures and cognitive measures as well as self-reported measures of depression, personality, and affective scales were examined. Results: Patients showed significant cortical thickening in the left superior frontal region compared to controls. Significant group differences were observed in sub-cortical volume measures in both hemispheres. Investigation of brain-behavior correlations revealed significant group differences in the correlation between cortical surface area and VF performance, although behavioral performance was equivalent between the two groups. The left middle temporal surface area was a significant predictor of VF performance with controls showing a significant positive correlation between these measures, and patients showing the opposite effect. Conclusion: Our results indicate key differences in structural brain measures in patients with CD compared to controls. Additionally, correlation between brain measures and behavioral responses suggest there may be a neural basis to the alterations in patients' cognitive and affective responses. PMID- 27695407 TI - Preserved Self-Evaluation in Amnesia Supports Access to the Self through Introspective Computation. AB - Encounters with new people result in the extraction and storage in memory of both their external features, allowing us to recognize them later, and their internal traits, allowing us to better control our current interactions with them and anticipate our future ones. Just as we extract, encode, store, retrieve and update the representations of others so, too, do we process representations of ourselves. These representations, which rely on declarative memory, may be altered or cease to be accessible in amnesia. Nonetheless, studies of amnesic patients have yielded the surprising observation that memory impairments alone do not prevent patients from making accurate trait self-judgments. In this review article, we discuss prevailing explanations for preserved self-evaluation in amnesia and propose an alternative one, based on the concept of introspective computation. We also consider molecular and anatomical aspects of brain functioning that potentially support introspective computation. PMID- 27695408 TI - Resting-State Time-Varying Analysis Reveals Aberrant Variations of Functional Connectivity in Autism. AB - Recently, studies based on time-varying functional connectivity have unveiled brain states diversity in some neuropsychiatric disorders, such as schizophrenia and major depressive disorder. However, time-varying functional connectivity analysis of resting-state functional Magnetic Resonance Imaging (fMRI) have been rarely performed on the Autism Spectrum Disorder (ASD). Hence, we performed time varying connectivity analysis on resting-state fMRI data to investigate brain states mutation in ASD children. ASD showed an imbalance of connectivity state and aberrant ratio of connectivity with different strengths in the whole brain network, and decreased connectivity associated precuneus/posterior cingulate gyrus with medial prefrontal gyrus in default mode network. As compared to typical development children, weak relevance condition (the strength of a large number of connectivities in the state was less than means minus standard deviation of all connection strength) was maintained for a longer time between brain areas of ASD children, and ratios of weak connectivity in brain states varied dramatically in the ASD. In the ASD, the abnormal brain state might be related to repetitive behaviors and stereotypical interests, and macroscopically reflect disruption of gamma-aminobutyric acid at the cellular level. The detection of brain states based on time-varying functional connectivity analysis of resting-state fMRI might be conducive for diagnosis and early intervention of ASD before obvious clinical symptoms. PMID- 27695410 TI - Functional Equivalence of Imagined vs. Real Performance of an Inhibitory Task: An EEG/ERP Study. AB - Early neuroimaging and electrophysiological studies suggested that motor imagery recruited a different network than motor execution. However, several studies have provided evidence for the involvement of the same circuits in motor imagery tasks, in the absence of overt responses. The present study aimed to test whether imagined performance of a stop-signal task produces a similar pattern of motor related EEG activity than that observed during real performance. To this end, mu and beta event-related desynchronization (ERD) and the Lateralized Readiness Potential (LRP) were analyzed. The study also aimed to clarify the functional significance of the Stop-N2 and Stop-P3 event-related potential (ERPs) components, which were also obtained during both real and imagined performance. The results showed a common pattern of brain electrical activity, and with a similar time course, during covert performance and overt execution of the stop signal task: presence of LRP and Stop-P3 in the imagined condition and identical LRP onset, and similar mu and beta ERD temporal windows for both conditions. These findings suggest that a similar inhibitory network may be activated during both overt and covert execution of the task. Therefore, motor imagery may be useful to improve inhibitory skills and to develop new communicating systems for Brain-Computer Interface (BCI) devices based on inhibitory signals. PMID- 27695409 TI - Contribution of Neuroimaging Studies to Understanding Development of Human Cognitive Brain Functions. AB - Humans experience significant physical and mental changes from birth to adulthood, and a variety of perceptual, cognitive and motor functions mature over the course of approximately 20 years following birth. To deeply understand such developmental processes, merely studying behavioral changes is not sufficient; simultaneous investigation of the development of the brain may lead us to a more comprehensive understanding. Recent advances in noninvasive neuroimaging technologies largely contribute to this understanding. Here, it is very important to consider the development of the brain from the perspectives of "structure" and "function" because both structure and function of the human brain mature slowly. In this review, we first discuss the process of structural brain development, i.e., how the structure of the brain, which is crucial when discussing functional brain development, changes with age. Second, we introduce some representative studies and the latest studies related to the functional development of the brain, particularly for visual, facial recognition, and social cognition functions, all of which are important for humans. Finally, we summarize how brain science can contribute to developmental study and discuss the challenges that neuroimaging should address in the future. PMID- 27695412 TI - Eye Movements Affect Postural Control in Young and Older Females. AB - Visual information is used for postural stabilization in humans. However, little is known about how eye movements prevalent in everyday life interact with the postural control system in older individuals. Therefore, the present study assessed the effects of stationary gaze fixations, smooth pursuits, and saccadic eye movements, with combinations of absent, fixed and oscillating large-field visual backgrounds to generate different forms of retinal flow, on postural control in healthy young and older females. Participants were presented with computer generated visual stimuli, whilst postural sway and gaze fixations were simultaneously assessed with a force platform and eye tracking equipment, respectively. The results showed that fixed backgrounds and stationary gaze fixations attenuated postural sway. In contrast, oscillating backgrounds and smooth pursuits increased postural sway. There were no differences regarding saccades. There were also no differences in postural sway or gaze errors between age groups in any visual condition. The stabilizing effect of the fixed visual stimuli show how retinal flow and extraocular factors guide postural adjustments. The destabilizing effect of oscillating visual backgrounds and smooth pursuits may be related to more challenging conditions for determining body shifts from retinal flow, and more complex extraocular signals, respectively. Because the older participants matched the young group's performance in all conditions, decreases of posture and gaze control during stance may not be a direct consequence of healthy aging. Further research examining extraocular and retinal mechanisms of balance control and the effects of eye movements, during locomotion, is needed to better inform fall prevention interventions. PMID- 27695411 TI - Organelle-Specific Sensors for Monitoring Ca2+ Dynamics in Neurons. AB - Calcium (Ca2+) plays innumerable critical functions in neurons ranging from regulation of neurotransmitter release and synaptic plasticity to activity dependent transcription. Therefore, more than any other cell types, neurons are critically dependent on spatially and temporally controlled Ca2+ dynamics. This is achieved through an exquisite level of compartmentalization of Ca2+ storage and release from various organelles. The function of these organelles in the regulation of Ca2+ dynamics has been studied for decades using electrophysiological and optical methods combined with pharmacological and genetic alterations. Mitochondria and the endoplasmic reticulum (ER) are among the organelles playing the most critical roles in Ca2+ dynamics in neurons. At presynaptic boutons, Ca2+ triggers neurotransmitter release and synaptic plasticity, and postsynaptically, Ca2+ mobilization mediates long-term synaptic plasticity. To explore Ca2+ dynamics in live cells and intact animals, various synthetic and genetically encoded fluorescent Ca2+ sensors were developed, and recently, many groups actively increased the sensitivity and diversity of genetically encoded Ca2+ indicators (GECIs). Following conjugation with various signal peptides, these improved GECIs can be targeted to specific subcellular compartments, allowing monitoring of organelle-specific Ca2+ dynamics. Here, we review recent findings unraveling novel roles for mitochondria- and ER-dependent Ca2+ dynamics in neurons and at synapses. PMID- 27695413 TI - Adult Body Height Is a Good Predictor of Different Dimensions of Cognitive Function in Aged Individuals: A Cross-Sectional Study. AB - Background: Adult height, weight, and adiposity measures have been suggested by some studies to be predictors of depression, cognitive impairment, and dementia. However, the presence of confounding factors and the lack of a thorough neuropsychological evaluation in many of these studies have precluded a definitive conclusion about the influence of anthropometric measures in cognition and depression. In this study we aimed to assess the value of height, weight, and abdominal perimeter to predict cognitive impairment and depressive symptoms in aged individuals. Methods and Findings: Cross-sectional study performed between 2010 and 2012 in the Portuguese general community. A total of 1050 participants were included in the study and randomly selected from local area health authority registries. The cohort was representative of the general Portuguese population with respect to age (above 50 years of age) and gender. Cognitive function was assessed using a battery of tests grouped in two dimensions: general executive function and memory. Two-step hierarchical multiple linear regression models were conducted to determine the predictive value of anthropometric measures in cognitive performance and mood before and after correction for possible confounding factors (gender, age, school years, physical activity, alcohol consumption, and smoking habits). We found single associations of weight, height, body mass index, abdominal perimeter, and age with executive function, memory and depressive symptoms. However, when included in a predictive model adjusted for gender, age, school years, and lifestyle factors only height prevailed as a significant predictor of general executive function (beta = 0.139; p < 0.001) and memory (beta = 0.099; p < 0.05). No relation was found between mood and any of the anthropometric measures studied. Conclusions and Relevance: Height is an independent predictor of cognitive function in late-life and its effects on the general and executive function and memory are independent of age, weight, education level, gender, and lifestyle factors. Altogether, our data suggests that modulators of adult height during childhood may irreversibly contribute to cognitive function in adult life and that height should be used in models to predict cognitive performance. PMID- 27695414 TI - Brooding Is Related to Neural Alterations during Autobiographical Memory Retrieval in Aging. AB - Brooding rumination is considered a central aspect of depression in midlife. As older people tend to review their past, rumination tendency might be particularly crucial in late life since it might hinder older adults to adequately evaluate previous events. We scanned 22 non-depressed older adults with varying degrees of brooding tendency with functional magnetic resonance imaging (MRI) while they performed the construction and elaboration of autobiographical memories. Behavioral findings demonstrate that brooders reported lower mood states, needed more time for memory construction and rated their memories as less detailed and less positive. On the neural level, brooding tendency was related to increased amygdala activation during the search for specific memories and reduced engagement of cortical networks during elaboration. Moreover, coupling patterns of the subgenual cingulate cortex with the hippocampus (HC) and the amygdala predicted details and less positive valence of memories in brooders. Our findings support the hypothesis that ruminative thinking interferes with the search for specific memories while facilitating the uncontrolled retrieval of negatively biased self-schemes. The observed neurobehavioral dysfunctions might put older people with brooding tendency at high risk for becoming depressed when reviewing their past. Training of autobiographical memory ability might therefore be a promising approach to increase resilience against depression in late-life. PMID- 27695415 TI - Turning Down the Thermostat: Modulating the Endocannabinoid System in Ocular Inflammation and Pain. AB - The endocannabinoid system (ECS) has emerged as an important regulator of both physiological and pathological processes. Notably, this endogenous system plays a key role in the modulation of pain and inflammation in a number of tissues. The components of the ECS, including endocannabinoids, their cognate enzymes and cannabinoid receptors, are localized in the eye, and evidence indicates that ECS modulation plays a role in ocular disease states. Of these diseases, ocular inflammation presents a significant medical problem, given that current clinical treatments can be ineffective or are associated with intolerable side-effects. Furthermore, a prominent comorbidity of ocular inflammation is pain, including neuropathic pain, for which therapeutic options remain limited. Recent evidence supports the use of drugs targeting the ECS for the treatment of ocular inflammation and pain in animal models; however, the potential for therapeutic use of cannabinoid drugs in the eye has not been thoroughly investigated at this time. This review will highlight evidence from experimental studies identifying components of the ocular ECS and discuss the functional role of the ECS during different ocular inflammatory disease states, including uveitis and corneal keratitis. Candidate ECS targeted therapies will be discussed, drawing on experimental results obtained from both ocular and non-ocular tissue(s), together with their potential application for the treatment of ocular inflammation and pain. PMID- 27695416 TI - Kidney Tissue Targeted Metabolic Profiling of Unilateral Ureteral Obstruction Rats by NMR. AB - Renal interstitial fibrosis is a common pathological process in the progression of kidney disease. A nuclear magnetic resonance (NMR) based metabolomic approach was used to analyze the kidney tissues of rats with renal interstitial fibrosis (RIF), induced by unilateral ureteral obstruction (UUO). The combination of a variety of statistical methods were used to screen out 14 significantly changed potential metabolites, which are related with multiple biochemical processes including amino acid metabolism, adenine metabolism, energy metabolism, osmolyte change and induced oxidative stress. The exploration of the contralateral kidneys enhanced the understanding of the disease, which was also supported by serum biochemistry and kidney histopathology results. In addition, the pathological parameters (clinical chemistry, histological and immunohistochemistry results) were correlated with the significantly changed differential metabolites related with RIF. This study showed that targeted tissue metabolomic analysis can be used as a useful tool to understand the mechanism of the disease and provide a novel insight in the pathogenesis of RIF. PMID- 27695417 TI - Antiplatelet Agents Inhibit the Generation of Platelet-Derived Microparticles. AB - Platelet microparticles (PMPs) contribute to thrombogenesis but the effects of antiplatelet drugs on PMPs generation is undefined. The present study investigated the cellular events regulating PMPs shedding, testing in vitro platelet agonists and inhibitors. Platelet-rich plasma from healthy subjects was stimulated with arachidonic acid (AA), U46619, collagen type-I (10 and 1.5 MUg/mL), epinephrine, ADP or TRAP-6 and pre-incubated with acetylsalicylic acid (ASA, 100 and 10 MUmol/L), SQ-29,548, apyrase, PSB-0739, or eptifibatide. PMPs were detected by flow-cytometry using CD61 and annexin-V as fluorescent markers. Platelet agonists induced annexin V-positive PMPs shedding. The strongest response was to high concentration collagen. ADP-triggered PMPs shedding was dose independent. ASA reduced PMPs induced by AA- (645, 347-2946 vs. 3061, 446-4901 PMPs/MUL; median ad range, n = 9, P < 0.001), collagen 10 MUg/mL (5317, 2027 15935 vs. 10252, 4187-46316 PMPs/MUL; n = 13, P < 0.001), collagen 1.5 MUg/mL (1078, 528-2820 vs. 1465, 582-5948 PMPs/MUL; n = 21, P < 0.001) and TRAP-6 (2008, 1621-2495 vs. 2840, 2404-3031 PMPs/MUL; n = 3, P < 0.01) but did not affect the response to epinephrine or ADP. The ADP scavenger apyrase reduced PMPs induced by U46619 (1256, 395-2908 vs. 3045, 1119-5494 PMPs/MUL, n = 6, P < 0.05), collagen 1.5 MUg/mL (1006, 780-1309 vs. 2422, 1839-3494 PMPs/MUL, n = 3, P < 0.01) and TRAP-6 (904, 761-1224 vs. 2840, 2404-3031 PMPs/MUL, n = 3, P < 0.01). The TP receptor antagonist SQ-29,548 and the P2Y12 receptor antagonist PSB-0739 markedly inhibited PMPs induced by low doses of collagen. Except for high-dose collagen, eptifibatide abolished agonist-induced PMPs release. Both TXA2 generation and ADP secretion are required as amplifiers of PMP shedding. The crucial role of the fibrinogen receptor and the collagen receptor in PMPs generation, independently of platelet aggregation, was identified. PMID- 27695419 TI - Antioxidant Effect of Sericin in Brain and Peripheral Tissues of Oxidative Stress Induced Hypercholesterolemic Rats. AB - This study evaluated the antioxidant effect of crude sericin extract (CSE) from Antheraea assamensis in high cholesterol fed rats. Investigation was conducted by administering graded oral dose of 0.25 and 0.5 gm/kg body weight (b.w.)/day of CSE for a period of 28 days. Experiments were conducted in 30 rats and were divided into five groups: normal control, high cholesterol fed (HCF), HCF + 0.065 gm/kg b.w./day fenofibrate (FF), HCF + sericin 0.25 gm/kg b.w./day (LSD), and HCF + sericin 0.5 gm/kg b.w./day (HSD). In brain, heart, liver, serum, and kidney homogenates nitric oxide (NO), thiobarbituric acid reactive substances (TBARS), protein carbonyl content (PCC), superoxide dismutase, reduced glutathione (GSH) was measured. LSD treatment prevented the alterations in GSH and PCC levels in hypercholesterolemic (HyC) brain tissue homogenates of rats. CSE lowers the serum total cholesterol level in HyC rats by promoting fecal cholesterol (FC) excretion. CSE increases FC level by promoting inhibition of cholesterol absorption in intestine. The endogenous antioxidant reduced significantly and the oxidative stress marker TBARS level increases significantly in the peripheral tissue of HCF rats. However, the administration of LSD and HSD exhibited a good antioxidant activity by reducing the TBARS level and increasing the endogenous antioxidant in peripheral tissue. In addition, a histological examination revealed loss of normal liver and kidney architecture in cholesterol fed rats which were retained in sericin treated groups. The findings of this study suggested that CSE improves hypercholesterolemia in rats fed a HyC diet. Clinical relevance of this effect of CSE seems worthy of further studies. PMID- 27695418 TI - Impact of Cannabis, Cannabinoids, and Endocannabinoids in the Lungs. AB - Since the identification of cannabinoid receptors in the 1990s, a research field has been dedicated to exploring the role of the cannabinoid system in immunity and the inflammatory response in human tissues and animal models. Although the cannabinoid system is present and crucial in many human tissues, studying the impact of cannabinoids on the lungs is particularly relevant because of their contact with exogenous cannabinoids in the context of marijuana consumption. In the past two decades, the scientific community has gathered a large body of evidence supporting that the activation of the cannabinoid system alleviates pain and reduces inflammation. In the context of lung inflammation, exogenous and endogenous cannabinoids have shown therapeutic potential because of their inhibitory effects on immune cell recruitment and functions. On the other hand, cannabinoids were shown to be deleterious to lung function and to impact respiratory pathogen clearance. In this review, we present the existing data on the regulation of lung immunity and inflammation by phytocannabinoids, synthetic cannabinoids and endocannabinoids. PMID- 27695420 TI - Goggatomy: A Method for Opening Small Cuticular Compartments in Arthropods for Physiological Experiments. AB - Most sense organs of arthropods are ensconced in small exoskeletal compartments that hinder direct access to plasma membranes. We have developed a method for exposing live sensory and supporting cells in such structures. The technique uses a viscous light cured resin to embed and support the structure, which is then sliced with a sharp blade. We term the procedure a "goggatomy," from the Khoisan word for a bug, gogga. To demonstrate the utility of the method we show that it can be used to expose the auditory chordotonal organs in the second antennal segment and the olfactory receptor neurons in the third antennal segment of Drosophila melanogaster, preserving the transduction machinery. The procedure can also be used on other small arthropods, like mosquitoes and mites to expose a variety of cells. PMID- 27695421 TI - Acute High-Intensity Interval Exercise-Induced Redox Signaling Is Associated with Enhanced Insulin Sensitivity in Obese Middle-Aged Men. AB - Background: Obesity and aging are associated with increased oxidative stress, activation of stress and mitogen activated protein kinases (SAPK), and the development of insulin resistance and metabolic disease. In contrast, acute exercise also increases oxidative stress and SAPK signaling, yet is reported to enhance insulin sensitivity and reduce the risk of metabolic disease. This study explored this paradox by investigating the effect of a single session of high intensity interval-exercise (HIIE) on redox status, muscle SAPK and insulin protein signaling in eleven middle-aged obese men. Methods: Participants completed a 2 h hyperinsulinaemic-euglycaemic clamp at rest, and 60 min after HIIE (4 * 4 mins at 95% HRpeak; 2 min recovery periods), separated by 1-3 weeks. Results: Irrespective of exercise-induced changes to redox status, insulin stimulation both at rest and after HIIE similarly increased plasma superoxide dismutase activity, plasma catalase activity, and skeletal muscle 4-HNE; and significantly decreased plasma TBARS and hydrogen peroxide. The SAPK signaling pathways of p38 MAPK, NF-kappaB p65, and JNK, and the distal insulin signaling protein AS160Ser588, were activated with insulin stimulation at rest and to a greater extent with insulin stimulation after a prior bout of HIIE. Higher insulin sensitivity after HIIE was associated with higher insulin-stimulated SOD activity, JNK, p38 MAPK and NF-kappaB phosphorylation (r = 0.63, r = 0.71, r = 0.72, r = 0.71; p < 0.05, respectively). Conclusion:These findings support a role for redox homeostasis and SAPK signaling in insulin-stimulated glucose uptake which may contribute to the enhancement of insulin sensitivity in obese men 3 h after HIIE. PMID- 27695422 TI - Intermittent Hypoxia Influences Alveolar Bone Proper Microstructure via Hypoxia Inducible Factor and VEGF Expression in Periodontal Ligaments of Growing Rats. AB - Intermittent hypoxia (IH) recapitulates morphological changes in the maxillofacial bones in children with obstructive sleep apnea (OSA). Recently, we found that IH increased bone mineral density (BMD) in the inter-radicular alveolar bone (reflecting enhanced osteogenesis) in the mandibular first molar (M1) region in the growing rats, but the underlying mechanism remains unknown. In this study, we focused on the hypoxia-inducible factor (HIF) pathway to assess the effect of IH by testing the null hypothesis of no significant differences in the mRNA-expression levels of relevant factors associated with the HIF pathway, between control rats and growing rats with IH. To test the null hypothesis, we investigated how IH enhances mandibular osteogenesis in the alveolar bone proper with respect to HIF-1alpha and vascular endothelial growth factor (VEGF) in periodontal ligament (PDL) tissues. Seven-week-old male Sprague-Dawley rats were exposed to IH for 3 weeks. The microstructure and BMD in the alveolar bone proper of the distal root of the mandibular M1 were evaluated using micro-computed tomography (micro-CT). Expression of HIF-1alpha and VEGF mRNA in PDL tissues were measured, whereas osteogenesis was evaluated by measuring mRNA levels for alkaline phosphatase (ALP) and bone morphogenetic protein-2 (BMP-2). The null hypothesis was rejected: we found an increase in the expression of all of these markers after IH exposure. The results provided the first indication that IH enhanced osteogenesis of the mandibular M1 region in association with PDL angiogenesis during growth via HIF-1alpha in an animal model. PMID- 27695423 TI - Resveratrol Supplementation Did Not Improve Cognition in Patients with Schizophrenia: Results from a Randomized Clinical Trial. AB - BACKGROUND: Schizophrenia (SZ) is associated with psychotic experiences and cognitive deficits. Therefore, cognitive function is one of the most critical determinants of quality of life in this pathology. Resveratrol has been related to neuroprotective action, but there are no studies evaluating resveratrol in SZ. The objective of this study was to determine the efficacy of resveratrol supplementation on cognition in individuals with SZ. METHODS: This is a 1-month randomized, double-blind, and controlled trial (NCT 02062190), in which 19 men with diagnosis of SZ, aged 18-65 years, were assigned to a resveratrol supplementation group (200 mg) or placebo group (200 mg), with a 1-month follow up. Applying a series of cognitive tests assessed neuropsychology performance (Hopkins Verbal Learning Test, Stroop Color and Word Test, and Weschler Adult Intelligence Scale) and Brief Psychiatric Rating Scale assessed psychopathology severity. RESULTS: There were no significant improvement in neuropsychology performance (episodic memory, working memory, attention and concentration capacity, inhibitory control, interference measures, selective attention, and mental flexibility) and psychopathology severity after 1 month of resveratrol supplementation (P > 0.05). CONCLUSION: In conclusion, we have shown that 1 month of a resveratrol supplementation (200 mg/day) did not improve episodic memory, working memory, attention and concentration capacity, inhibitory control, interference measures, selective attention, and mental flexibility as compared with placebo in patients with SZ. PMID- 27695424 TI - Being Moved by Unfamiliar Sad Music Is Associated with High Empathy. AB - The paradox of enjoying listening to music that evokes sadness is yet to be fully understood. Unlike prior studies that have explored potential explanations related to lyrics, memories, and mood regulation, we investigated the types of emotions induced by unfamiliar, instrumental sad music, and whether these responses are consistently associated with certain individual difference variables. One hundred and two participants were drawn from a representative sample to minimize self-selection bias. The results suggest that the emotional responses induced by unfamiliar sad music could be characterized in terms of three underlying factors: Relaxing sadness, Moving sadness, and Nervous sadness. Relaxing sadness was characterized by felt and perceived peacefulness and positive valence. Moving sadness captured an intense experience that involved feelings of sadness and being moved. Nervous sadness was associated with felt anxiety, perceived scariness and negative valence. These interpretations were supported by indirect measures of felt emotion. Experiences of Moving sadness were strongly associated with high trait empathy and emotional contagion, but not with other previously suggested traits such as absorption or nostalgia-proneness. Relaxing sadness and Nervous sadness were not significantly predicted by any of the individual difference variables. The findings are interpreted within a theoretical framework of embodied emotions. PMID- 27695425 TI - ACC Neuro-over-Connectivity Is Associated with Mathematically Modeled Additional Encoding Operations of Schizophrenia Stroop-Task Performance. AB - Functional magnetic resonance imaging at 7.0 Tesla was undertaken among Schizophrenia participants (Sz), and clinical (major mood disorder; MDD) and healthy controls (HC), during performance of the Stoop task. Stroop conditions included congruent and incongruent word color items, color-only items, and word only items. Previous modeling results extended to this most widely used selective attention task. All groups executed item-encoding operations (subprocesses of the item encoding process) at the same rate (performance accuracy being similarly high throughout), thus displaying like processing capacity; Sz participants, however, employed more subprocesses for item completions than did the MDD participants, who in turn used more subprocesses than the HC group. The reduced efficiency in deploying cognitive-workload capacity among the Sz participants was paralleled by more diffuse neuroconnectivity (Blood-Oxygen-Level-Dependent co activation) with the anterior cingulate cortex (ACC) (Broadman Area 32), spreading away from this encoding-intensive region; and by less evidence of network dissociation across Stroop conditions. Estimates of cognitive work done to accomplish item completion were greater for the Sz participants, as were estimates of entropy in both the modeled trial-latency distribution, and its associated neuro-circuitry. Findings are held to be symptom and assessment significant, and to have potential implications for clinical intervention.

AB - Mathematical disability (MD) is a neurodevelopmental disorder affecting math abilities. Here, we propose a new explanatory account of MD, the procedural deficit hypothesis (PDH), which may further our understanding of the disorder. According to the PDH of MD, abnormalities of brain structures subserving the procedural memory system can lead to difficulties with math skills learned in this system, as well as problems with other functions that depend on these brain structures. This brain-based account is motivated in part by the high comorbidity between MD and language disorders such as dyslexia that may be explained by the PDH, and in part by the likelihood that learning automatized math skills should depend on procedural memory. Here, we first lay out the PDH of MD, and present specific predictions. We then examine the existing literature for each prediction, while pointing out weaknesses and gaps to be addressed by future research. Although we do not claim that the PDH is likely to fully explain MD, we do suggest that the hypothesis could have substantial explanatory power, and that it provides a useful theoretical framework that may advance our understanding of the disorder.

AB - This study presents the first two ERP reading studies of comma-induced effects of covert (implicit) prosody on syntactic parsing decisions in English. The first experiment used a balanced 2 * 2 design in which the presence/absence of commas determined plausibility (e.g., John, said Mary, was the nicest boy at the party vs. John said Mary was the nicest boy at the party). The second reading experiment replicated a previous auditory study investigating the role of overt prosodic boundaries in closure ambiguities (Pauker et al., 2011). In both experiments, commas reliably elicited CPS components and generally played a dominant role in determining parsing decisions in the face of input ambiguity. The combined set of findings provides further evidence supporting the claim that mechanisms subserving speech processing play an active role during silent reading. PMID- 27695429 TI - Does Loneliness Necessarily Lead to a Decrease in Prosocial Behavior? The Roles of Gender and Situation. AB - Although, previous studies show overwhelming evidence that loneliness is negatively correlated with prosocial behavior, some theories and research have implied that under certain situations, loneliness plays a positive role in an individual's social functioning. The two studies reported in this article examined loneliness and its associations with prosocial behavior in Chinese adults using subjective reporting and experimental design. Study 1 examined 305 Chinese adults (175 males) using the Social and Emotional Loneliness Scale for Adults and the Prosocial Tendencies Measure to evaluate their loneliness and prosocial tendencies. The results showed that loneliness was negatively associated with all prosocial tendencies except the public prosocial tendency. Study 2 examined 177 Chinese adults (61 males) using an experimental design and found that only lonely women in public situations expressed a greater willingness to help. The results also suggest that loneliness may play a positive role in the social functioning of individuals under certain conditions. The function of loneliness and the implications of the association between loneliness and prosocial behavior are discussed. PMID- 27695431 TI - Semantic Richness Effects in Syntactic Classification: The Role of Feedback. AB - Words with richer semantic representations are recognized faster across a range of lexical processing tasks. The most influential account of this finding is based on the idea that semantic richness effects are mediated by feedback from semantic-level to lower-level representations. In an earlier lexical decision study, Yap et al. (2015) tested this claim by examining the joint effects of stimulus quality and four semantic richness dimensions (imageability, number of features, semantic neighborhood density, semantic diversity). The results of that study showed that joint effects of stimulus quality and richness were generally additive, consistent with the idea that semantic feedback does not typically reach the earliest levels of representation in lexical decision. The present study extends this earlier work by investigating the joint effects of stimulus quality and the same four semantic richness dimensions on syntactic classification performance (is this a noun or verb?), which places relatively more emphasis on semantic processing. Additive effects of stimulus quality and richness were found for two of the four targeted dimensions (concreteness, number of features) while semantic neighborhood density and semantic diversity did not seem to influence syntactic classification response times. These findings provide further support against the view that semantic information reaches early letter level processes. PMID- 27695430 TI - Action Sounds Modulate Arm Reaching Movements. AB - Our mental representations of our body are continuously updated through multisensory bodily feedback as we move and interact with our environment. Although it is often assumed that these internal models of body-representation are used to successfully act upon the environment, only a few studies have actually looked at how body-representation changes influence goal-directed actions, and none have looked at this in relation to body-representation changes induced by sound. The present work examines this question for the first time. Participants reached for a target object before and after adaptation periods during which the sounds produced by their hand tapping a surface were spatially manipulated to induce a representation of an elongated arm. After adaptation, participants' reaching movements were performed in a way consistent with having a longer arm, in that their reaching velocities were reduced. These kinematic changes suggest auditory-driven recalibration of the somatosensory representation of the arm morphology. These results provide support to the hypothesis that one's represented body size is used as a perceptual ruler to measure objects' distances and to accordingly guide bodily actions. PMID- 27695432 TI - The Effect of Number and Presentation Order of High-Constraint Sentences on Second Language Word Learning. AB - This paper presents the results of an experiment that investigated the effects of number and presentation order of high-constraint sentences on semantic processing of unknown second language (L2) words (pseudowords) through reading. All participants were Chinese native speakers who learned English as a foreign language. In the experiment, sentence constraint and order of different constraint sentences were manipulated in English sentences, as well as L2 proficiency level of participants. We found that the number of high-constraint sentences was supportive for L2 word learning except in the condition in which high-constraint exposure was presented first. Moreover, when the number of high constraint sentences was the same, learning was significantly better when the first exposure was a high-constraint exposure. And no proficiency level effects were found. Our results provided direct evidence that L2 word learning benefited from high quality language input and first presentations of high quality language input. PMID- 27695433 TI - "Female Preponderance" of Depression in Non-clinical Populations: A Meta-Analytic Study. AB - Clinical observations and research suggest a female preponderance in major depressive disorder. However, it is unclear whether a similar gender difference is found for the reporting of depressive symptoms in non-clinical populations. The present meta-analysis was conducted to address this issue. We searched for published papers targeting non-clinical populations in which the 21-item Beck Depression Inventory (BDI) was used. Eighty-four papers (91 studies) published between 1977 and 2014 were included in the final meta-analysis, which comprised 23,579 males and 29,470 females. Females in the general population reported higher level of depressive symptoms than males (d = -0.187, corresponding to 1.159 points in the 21-item BDI). This pattern was not found to influence by years of publication, socioeconomic status, or version of the BDI used. Using age group as a moderator, studies with adolescents and young adults were found to show a smaller effect size than studies with older participants. Our results appear to confirm the "female preponderance" in the level of self-report depressive symptoms in the general population, and support the social gender role theory in explaining gender difference over biological susceptibility theory and evolutionary theory. PMID- 27695434 TI - Neural Mechanisms of Dorsal and Ventral Visual Regions during Text Reading. AB - When reading a narrative text, both the dorsal and ventral visual systems are activated. To illustrate the patterns of interactions between the dorsal and ventral visual systems in text reading, we conducted analyses of functional connectivity (FC) and effective connectivity (EC) in a left-hemispheric network for reading-driven functional magnetic resonance imaging (fMRI) and resting-state fMRI (rs-fMRI) data. In reading-driven fMRI (Experiment 1), we found significant FCs among the left middle frontal gyrus (MFG), the left intraparietal sulcus (IPS), and the visual word form area (VWFA), and there were top-down effects from the left MFG to the left IPS, from the left MFG to the VWFA, and from the left IPS to the VWFA. In rs-fMRI (Experiment 2), we identified FCs and ECs for MFG-IPS and IPS-VWFA connections. In addition, the brain-behavior relationship in resting states showed that the dorsal connection was more associated with reading fluency relative to lexical decision. The combination of two experiments revealed that the MFG-IPS and the VWFA-IPS connections were shared connections both in reading driven fMRI and rs-fMRI, and that the MFG-VWFA was specific connectivity in reading-driven fMRI. These results suggest that top-down effects from the dorsal visual system to ventral visual system play an important role in text reading. PMID- 27695435 TI - "PHE in Action": Development and Modeling of an Intervention to Improve Patient Engagement among Older Adults. AB - The increasing prevalence of chronic conditions among older adults constitutes a major public health problem. Thus, changes in lifestyles are required to prevent secondary conditions and sustain good care practices. While patient engagement received great attention in the last years as key strategy to solve this issue, to date no interventions exist to sustain the engagement of older chronic patients toward their health management. This study describes the design, development, and optimization of PHEinAction, a theoretically-driven intervention program to increase patient engagement in older chronic populations and consequently to foster healthy changes that can help reduce risks of health problems. The development process followed the UK Medical Research Council's (MRC) guidelines and involved selecting the theoretical base for the intervention, identifying the relevant evidence-based literature, and conducting exploratory research to qualitatively evaluate program's feasibility, acceptability, and comprehension. The result was a user-endorsed intervention designed to improve older patients' engagement in health management based on the theoretical framework of the Patient Health Engagement (PHE) model. The intervention program, which emerged from this process, consisted of 2 monthly face-to-face 1-h sessions delivered by a trained facilitator and one brief telephonic consultation, and aimed to facilitate a range of changes for patient engagement (e.g., motivation to change, health information seeking and use, emotional adjustment, health behaviors planning). PHEinAction is the first example of a theoretically-based patient engagement intervention designed for older chronic targets. The intervention program is based on psychological theory and evidence; it facilitates emotional, psychological, and behavioral processes to support patient engagement and lifestyle change and maintenance. It provides estimates of the extent to which it could help high-risk groups engage in effective health management and informs future trials. PMID- 27695436 TI - Understanding the Relationship between Rainstorm-Related Experiences and PTSD among Chinese Adolescents after Rainstorm Disaster: The Roles of Rumination and Social Support. AB - Posttraumatic stress disorder (PTSD) is prevalent among adolescents following natural disasters, and the trauma experiences represent a critical risk factor for PTSD. Nevertheless, the underlying mechanism of adolescents' PTSD following trauma experiences remains unclear. Rumination appears to be a mediating factor between trauma experiences and PTSD, and social support may moderate this mediating relationship between trauma experiences, rumination, and PTSD, but few studies have examined these assumptions. Thus, this study aimed to assess the mediating role of rumination and the moderating role of social support in the relationship between rainstorm-related experiences and PTSD among adolescents, following a rainstorm in China. Nine hundred and fifty-one middle school students completed self-report questionnaires, and structural equation modeling was conducted to examine the potential moderated mediation effect. Rainstorm-related experiences had a direct and positive effect on PTSD, and also indirectly influenced PTSD via rumination. Moreover, social support work to buffer the direct effect of rainstorm-related experiences on PTSD, but not the effect of rumination on PTSD. Implications for clinical practice and research are discussed along with study limitations. PMID- 27695437 TI - Determinants for a Successful Semont Maneuver: An In vitro Study with a Semicircular Canal Model. AB - OBJECTIVE: To evaluate the effect of time between the movements/steps, angle of body movements as well as the angular velocity of the maneuvers in an in vitro model of a semicircular canal (SCC) to improve the efficacy of the Semont maneuver (SM) in benign paroxysmal positional vertigo. MATERIALS AND METHODS: Semont maneuvers were performed on an in vitro SCC model. Otoconia trajectories were captured by a video camera. The effects of time between the movements, angles of motion (0 degrees , 10 degrees , 20 degrees , and 30 degrees below the horizontal line), different angular velocities (90, 135, 180 degrees /s), and otoconia size (36 and 50 MUm) on the final position of the otoconia in the SCC were tested. RESULTS: Without extension of the movements beyond the horizontal, the in vitro experiments (with particles corresponding to 50 MUm diameter) did not yield successful canalith repositioning. If the movements were extended by 20 degrees beyond the horizontal position, SM were successful with resting times of at least 16 s. For larger extension angles, the required time decreased. However, for smaller particles (36 MUm), the required time doubled. The angular maneuver velocity (tested between 90 and 180 degrees /s) did not have a major impact on the final position of the otoconia. INTERPRETATION: The two primary determinants for success of the SM are the time between the movements and the extension of the movements beyond the horizontal. The time between the movements should be at least 45 s. Angles of 20 degrees or more below horizontal line (so-called Semont+) should increase the success rate of SM. PMID- 27695438 TI - Increased Bone Marrow Adiposity in a Context of Energy Deficit: The Tip of the Iceberg? AB - Elevated bone marrow adiposity (BMA) is defined as an increase in the proportion of the bone marrow (BM) cavity volume occupied by adipocytes. This can be caused by an increase in the size and/or number of adipocytes. BMA increases with age in a bone-site-specific manner. This increase may be linked to certain pathophysiological situations. Osteoporosis or compromised bone quality is frequently associated with high BMA. The involvement of BM adipocytes in bone loss may be due to commitment of mesenchymal stem cells to the adipogenic pathway rather than the osteogenic pathway. However, adipocytes may also act on their microenvironment by secreting factors with harmful effects for the bone health. Here, we review evidence that in a context of energy deficit (such as anorexia nervosa (AN) and restriction rodent models) bone alterations can occur in the absence of an increase in BMA. In severe cases, bone alterations are even associated with gelatinous BM transformation. The relationship between BMA and energy deficit and the potential regulators of this adiposity in this context are also discussed. On the basis of clinical studies and preliminary results on animal model, we propose that competition between differentiation into osteoblasts and differentiation into adipocytes might trigger bone loss at least in moderate-to-severe AN and in some calorie restriction models. Finally, some of the main questions resulting from this hypothesis are discussed. PMID- 27695439 TI - Encapsulation into Stealth Liposomes Enhances the Antitumor Action of Recombinant Cratylia mollis Lectin Expressed in Escherichia coli. AB - This study evaluated the in vivo antitumor potential of the recombinant lectin from seeds of Cratylia mollis (rCramoll) expressed in Escherichia coli, free or encapsulated in stealth liposomes, using mice transplanted with sarcoma 180. rCramoll-loaded stealth liposomes (rCramoll-lipo) were formulated by hydration of the lipid film followed by cycles of freezing and thawing, and about 60% of rCramoll was encapsulated. This novel preparation showed particle size, polydispersity index, and pH suitable for the evaluation of antitumor activity in vivo. Tumor growth inhibition rates were 59% for rCramoll and 75% for rCramoll lipo. Histopathological analysis of the experimental groups showed that both free and encapsulated lectin caused no changes in the kidneys of animals. Hematological analysis revealed that treatment with rCramoll-lipo significantly increased leukocyte concentration when compared with the untreated and rCramoll group. In conclusion, the encapsulation of rCramoll in stealth liposomes improves its antitumor activity without substantial toxicity; this approach was more successful than the previous results reported for pCramoll loaded into conventional liposomes. At this point, a crucial difference between the antitumor action of free and encapsulated rCramoll was found along with their effects on immune cells. Further investigations are required to elucidate the mechanism(s) of the antitumor effect induced by rCramoll. PMID- 27695440 TI - Nanotechnology: A Valuable Strategy to Improve Bacteriocin Formulations. AB - Bacteriocins are proteinaceous antibacterial compounds, produced by diverse bacteria, which have been successfully used as: (i) food biopreservative; (ii) anti-biofilm agents; and (iii) additives or alternatives to the currently existing antibiotics, to minimize the risk of emergence of resistant strains. However, there are several limitations that challenge the use of bacteriocins as biopreservatives/antibacterial agents. One of the most promising avenues to overcome these limitations is the use of nanoformulations. This review highlights the practical difficulties with using bacteriocins to control pathogenic microorganisms, and provides an overview on the role of nanotechnology in improving the antimicrobial activity and the physicochemical properties of these peptides. PMID- 27695442 TI - Applicability of an in-House Saponin-Based Extraction Method in Bruker Biotyper Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry System for Identification of Bacterial and Fungal Species in Positively Flagged Blood Cultures. AB - We used an in-house saponin-based extraction method to evaluate the performance of the Bruker Biotyper matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) system for the identification of bacteria and fungi in 405 positively flagged blood culture bottles. Results obtained from MALDI-TOF/MS were compared with those obtained using conventional phenotypic identification methods. Of the 405 positively flagged blood culture bottles, 365 showed monomicrobal growth and were correctly identified to the species (72.1%) or genus (89.6%) level using the Bruker Biotyper system. The remaining 40 positively flagged blood culture bottles showed polymicrobial growth. Of them, 82.5% (n = 33) of the isolates were correctly identified to the species level and 92.5% (n = 37) to the genus level using the Bruker Biotyper system. The overall accuracy of identification to the genus level in flagged blood cultures was 89.5% for Gram-positive organisms, 93.5% for Gram-negative pathogens and 71.9% for fungi. Confidence scores were >=1.500 for 307 (75.8%) bottles, >=1.700 for 249 (61.5%) bottles and >=2.000 for 142 (35.1%) bottles. None of the yeast cultures yielded scores >=1.700. Using an identification-score cutoff of >=1.500, the MALDI Biotyper correctly identified 99.2% of Gram-positive bacteria, 97.6% of Gram-negative bacteria and 100% of yeast isolates to the genus level and 77.6% of Gram-positive bacteria, 87.1% of Gram-negative bacteria and 100.0% of yeast isolates to the species level. The overall rate of identification using our protocol was 89.9% (364/405) for genus level identification and 73.1% (296/405) for species level identification. Yeast isolates yielded the lowest confidence scores, which compromised the accuracy of identification. Further optimization of the protein extraction procedure in positive blood cultures is needed to improve the rate of identification. PMID- 27695441 TI - High Frequency of Thermodesulfovibrio spp. and Anaerolineaceae in Association with Methanoculleus spp. in a Long-Term Incubation of n-Alkanes-Degrading Methanogenic Enrichment Culture. AB - In the present study, the microbial community and functional gene composition of a long-term active alkane-degrading methanogenic culture was established after two successive enrichment culture transfers and incubated for a total period of 1750 days. Molecular analysis was conducted after the second transfer (incubated for 750 days) for both the active alkanes-degrading methanogenic enrichment cultures (T2-AE) and the background control (T2-BC). A net increase of methane as the end product was detected in the headspace of the enrichment cultures amended with long-chain n-alkanes and intermediate metabolites, including octadecanoate, hexadecanoate, isocaprylate, butyrate, isobutyrate, propionate, acetate, and formate were measured in the liquid cultures. The composition of microbial community shifted through the successive transfers over time of incubation. Sequences of bacterial and archaeal 16S rRNA gene (16S rDNA) and mcrA functional gene indicated that bacterial sequences affiliated to Thermodesulfovibrio spp. and Anaerolineaceae and archaeal sequences falling within the genus Methanoculleus were the most frequently encountered and thus represented the dominant members performing the anaerobic degradation of long-chain n-alkanes and methanogenesis. In addition, the presence of assA functional genes encoding the alkylsuccinate synthase alpha subunit indicated that fumarate addition mechanism could be considered as a possible initial activation step of n-alkanes in the present study. The succession pattern of microbial communities indicates that Thermodesulfovibrio spp. could be a generalist participating in the metabolism of intermediates, while Anaerolineaceae plays a key role in the initial activation of long-chain n-alkane biodegradation. PMID- 27695443 TI - Physical Forces Shape Group Identity of Swimming Pseudomonas putida Cells. AB - The often striking macroscopic patterns developed by motile bacterial populations on agar plates are a consequence of the environmental conditions where the cells grow and spread. Parameters such as medium stiffness and nutrient concentration have been reported to alter cell swimming behavior, while mutual interactions among populations shape collective patterns. One commonly observed occurrence is the mutual inhibition of clonal bacteria when moving toward each other, which results in a distinct halt at a finite distance on the agar matrix before having direct contact. The dynamics behind this phenomenon (i.e., intolerance to mix in time and space with otherwise identical others) has been traditionally explained in terms of cell-to-cell competition/cooperation regarding nutrient availability. In this work, the same scenario has been revisited from an alternative perspective: the effect of the physical mechanics that frame the process, in particular the consequences of collisions between moving bacteria and the semi solid matrix of the swimming medium. To this end, we set up a simple experimental system in which the swimming patterns of Pseudomonas putida were tested with different geometries and agar concentrations. A computational analysis framework that highlights cell-to-medium interactions was developed to fit experimental observations. Simulated outputs suggested that the medium is compressed in the direction of the bacterial front motion. This phenomenon generates what was termed a compression wave that goes through the medium preceding the swimming population and that determines the visible high-level pattern. Taken together, the data suggested that the mechanical effects of the bacteria moving through the medium created a factual barrier that impedes to merge with neighboring cells swimming from a different site. The resulting divide between otherwise clonal bacteria is thus brought about by physical forces-not genetic or metabolic programs. PMID- 27695444 TI - Riverine Bacterial Communities Reveal Environmental Disturbance Signatures within the Betaproteobacteria and Verrucomicrobia. AB - Riverine bacterial communities play an essential role in the biogeochemical coupling of terrestrial and marine environments, transforming elements and organic matter in their journey from land to sea. However, precisely due to the fact that rivers receive significant terrestrial input, the distinction between resident freshwater taxa vs. land-derived microbes can often become ambiguous. Furthermore, ecosystem perturbations could introduce allochthonous microbial groups and reshape riverine bacterial communities. Using full- and partial-length 16S ribosomal RNA gene sequences, we analyzed the composition of bacterial communities in the Tar River of North Carolina from November 2010 to November 2011, during which a natural perturbation occurred: the inundation of the lower reaches of an otherwise drought-stricken river associated with Hurricane Irene, which passed over eastern North Carolina in late August 2011. This event provided the opportunity to examine the microbiological, hydrological, and geochemical impacts of a disturbance, defined here as the large freshwater influx into the Tar River, superimposed on seasonal changes or other ecosystem variability independent of the hurricane. Our findings demonstrate that downstream communities are more taxonomically diverse and temporally variable than their upstream counterparts. More importantly, pre- vs. post-disturbance taxonomic comparison of the freshwater-dominant Betaproteobacteria class and the phylum Verrucomicrobia reveal a disturbance signature of previously undetected taxa of diverse origins. We use known traits of closely-related taxa to interpret the ecological function of disturbance-associated bacteria, and hypothesize that carbon cycling was enhanced post-disturbance in the Tar River, likely due to the flux of organic carbon into the system associated with the large freshwater pulse. Our analyses demonstrate the importance of geochemical and hydrological alterations in structuring bacterial communities, and illustrate the response of temperate riverine bacteria on fine taxonomic scales to a disturbance. PMID- 27695445 TI - CCR4-Not Complex Subunit Not2 Plays Critical Roles in Vegetative Growth, Conidiation and Virulence in Watermelon Fusarium Wilt Pathogen Fusarium oxysporum f. sp. niveum. AB - CCR4-Not complex is a multifunctional regulator that plays important roles in multiple cellular processes in eukaryotes. In the present study, the biological function of FonNot2, a core subunit of the CCR4-Not complex, was explored in Fusarium oxysporum f. sp. niveum (Fon), the causal agent of watermelon wilt disease. FonNot2 was expressed at higher levels in conidia and germinating conidia and during infection in Fon-inoculated watermelon roots than in mycelia. Targeted disruption of FonNot2 resulted in retarded vegetative growth, reduced conidia production, abnormal conidial morphology, and reduced virulence on watermelon. Scanning electron microscopy observation of infection behaviors and qRT-PCR analysis of in planta fungal growth revealed that the DeltaFonNot2 mutant was defective in the ability to penetrate watermelon roots and showed reduced fungal biomass in root and stem of the inoculated plants. Phenotypic and biochemical analyses indicated that the DeltaFonNot2 mutant displayed hypersensitivity to cell wall perturbing agents (e.g., Congo Red and Calcofluor White) and oxidative stress (e.g., H2O2 and paraquat), decreased fusaric acid content, and reduced reactive oxygen species (ROS) production during spore germination. Our data demonstrate that FonNot2 plays critical roles in regulating vegetable growth, conidiogenesis and conidia morphology, and virulence on watermelon via modulating cell wall integrity, oxidative stress response, ROS production and FA biosynthesis through the regulation of transcription of genes involved in multiple pathways. PMID- 27695446 TI - Interplays between Soil-Borne Plant Viruses and RNA Silencing-Mediated Antiviral Defense in Roots. AB - Although the majority of plant viruses are transmitted by arthropod vectors and invade the host plants through the aerial parts, there is a considerable number of plant viruses that infect roots via soil-inhabiting vectors such as plasmodiophorids, chytrids, and nematodes. These soil-borne viruses belong to diverse families, and many of them cause serious diseases in major crop plants. Thus, roots are important organs for the life cycle of many viruses. Compared to shoots, roots have a distinct metabolism and particular physiological characteristics due to the differences in development, cell composition, gene expression patterns, and surrounding environmental conditions. RNA silencing is an important innate defense mechanism to combat virus infection in plants, but the specific information on the activities and molecular mechanism of RNA silencing-mediated viral defense in root tissue is still limited. In this review, we summarize and discuss the current knowledge regarding RNA silencing aspects of the interactions between soil-borne viruses and host plants. Overall, research evidence suggests that soil-borne viruses have evolved to adapt to the distinct mechanism of antiviral RNA silencing in roots. PMID- 27695447 TI - Production of the Bioactive Compounds Violacein and Indolmycin Is Conditional in a maeA Mutant of Pseudoalteromonas luteoviolacea S4054 Lacking the Malic Enzyme. AB - It has previously been reported that some strains of the marine bacterium Pseudoalteromonas luteoviolacea produce the purple bioactive pigment violacein as well as the antibiotic compound indolmycin, hitherto only found in Streptomyces. The purpose of the present study was to determine the relative role of each of these two compounds as antibacterial compounds in P. luteoviolacea S4054. Using Tn10 transposon mutagenesis, a mutant strain that was significantly reduced in violacein production in mannose-containing substrates was created. Full genome analyses revealed that the vio-biosynthetic gene cluster was not interrupted by the transposon; instead the insertion was located to the maeA gene encoding the malic enzyme. Supernatant of the mutant strain inhibited Vibrio anguillarum and Staphylococcus aureus in well diffusion assays and in MIC assays at the same level as the wild type strain. The mutant strain killed V. anguillarum in co culture experiments as efficiently as the wild type. Using UHPLC-UV/Vis analyses, we quantified violacein and indolmycin, and the mutant strain only produced 7-10% the amount of violacein compared to the wild type strain. In contrast, the amount of indolmycin produced by the mutant strain was about 300% that of the wild type. Since inhibition of V. anguillarum and S. aureus by the mutant strain was similar to that of the wild type, it is concluded that violacein is not the major antibacterial compound in P. luteoviolacea. We furthermore propose that production of violacein and indolmycin may be metabolically linked and that yet unidentified antibacterial compound(s) may be play a role in the antibacterial activity of P. luteoviolacea. PMID- 27695448 TI - Proteomics Analysis Revealed that Crosstalk between Helicobacter pylori and Streptococcus mitis May Enhance Bacterial Survival and Reduces Carcinogenesis. AB - Helicobacter pylori is the dominant species of the human gastric microbiota and is present in the stomach of more than half of the human population worldwide. Colonization by H. pylori causes persistent inflammatory response and H. pylori induced gastritis is the strongest singular risk factor for the development of gastric adenocarcinoma. However, only a small proportion of infected individuals develop malignancy. Besides H. pylori, other microbial species have also been shown to be related to gastritis. We previously reported that interspecies microbial interaction between H. pylori and S. mitis resulted in alteration of their metabolite profiles. In this study, we followed up by analyzing the changing protein profiles of H. pylori and S. mitis by LC/Q-TOF mass spectrometry to understand the different response of the two bacterial species in a multi species micro-environment. Differentially-expressed proteins in mono- and co cultures could be mapped into 18 biological pathways. The number of proteins involve in RNA degradation, nucleotide excision repair, mismatch repair, and lipopolysaccharide (LPS) biosynthesis were increased in co-cultured H. pylori. On the other hand, fewer proteins involve in citrate cycle, glycolysis/ gluconeogenesis, aminoacyl-tRNA biosynthesis, translation, metabolism, and cell signaling were detected in co-cultured H. pylori. This is consistent with our previous observation that in the presence of S. mitis, H. pylori was transformed to coccoid. Interestingly, phosphoglycerate kinase (PGK), a major enzyme used in glycolysis, was found in abundance in co-cultured S. mitis and this may have enhanced the survival of S. mitis in the multi-species microenvironment. On the other hand, thioredoxin (TrxA) and other redox-regulating enzymes of H. pylori were less abundant in co-culture possibly suggesting reduced oxidative stress. Oxidative stress plays an important role in tissue damage and carcinogenesis. Using the in vitro co-culture model, this study emphasized the possibility that pathogen-microbiota interaction may have a protective effect against H. pylori associated carcinogenesis. PMID- 27695450 TI - Genetic and Phenotypic Characterization of a Salmonella enterica serovar Enteritidis Emerging Strain with Superior Intra-macrophage Replication Phenotype. AB - Salmonella enterica serovar Enteritidis (S. Enteritidis) is one of the ubiquitous Salmonella serovars worldwide and a major cause of food-born outbreaks, which are often associated with poultry and poultry derivatives. Here we report a nation wide S. Enteritidis clonal outbreak that occurred in Israel during the last third of 2015. Pulsed field gel electrophoresis and whole genome sequencing identified genetically related strains that were circulating in Israel as early as 2008. Global comparison linked this outbreak strain to several clinical and marine environmental isolates that were previously isolated in California and Canada, indicating that similar strains are prevalent outside of Israel. Phenotypic comparison between the 2015 outbreak strain and other clinical and reference S. Enteritidis strains showed only limited intra-serovar phenotypic variation in growth in rich medium, invasion into Caco-2 cells, uptake by J774.1A macrophages, and host cell cytotoxicity. In contrast, significant phenotypic variation was shown among different S. Enteritidis isolates when biofilm-formation, motility, invasion into HeLa cells and uptake by THP-1 human macrophages were studied. Interestingly, the 2015 outbreak clone was found to possess superior intra macrophage replication ability within both murine and human macrophages in comparison to the other S. Enteritidis strains studied. This phenotype is likely to play a role in the virulence and host-pathogen interactions of this emerging clone.

AB - Pyrethroid insecticides have been used to control pests in agriculture, forestry, horticulture, public health and for indoor home use for more than 20 years. Because pyrethroids were considered to be a safer alternative to organophosphate pesticides (OPs), their applications significantly increased when the use of OPs was banned or limited. Although, pyrethroids have agricultural benefits, their widespread and continuous use is a major problem as they pollute the terrestrial and aquatic environments and affect non-target organisms. Since pyrethroids are not degraded immediately after application and because their residues are detected in soils, there is an urgent need to remediate pyrethroid-polluted environments. Various remediation technologies have been developed for this purpose; however, bioremediation, which involves bioaugmentation and/or biostimulation and is a cost-effective and eco-friendly approach, has emerged as the most advantageous method for cleaning-up pesticide-contaminated soils. This review presents an overview of the microorganisms that have been isolated from pyrethroid-polluted sites, characterized and applied for the degradation of pyrethroids in liquid and soil media. The paper is focused on the microbial degradation of the pyrethroids that have been most commonly used for many years such as allethrin, bifenthrin, cyfluthrin, cyhalothrin, cypermethrin, deltamethrin, fenpropathrin, fenvalerate, and permethrin. Special attention is given to the bacterial strains from the genera Achromobacter, Acidomonas, Bacillus, Brevibacterium, Catellibacterium, Clostridium, Lysinibacillus, Micrococcus, Ochrobactrum, Pseudomonas, Serratia, Sphingobium, Streptomyces, and the fungal strains from the genera Aspergillus, Candida, Cladosporium, and Trichoderma, which are characterized by their ability to degrade various pyrethroids. Moreover, the current knowledge on the degradation pathways of pyrethroids, the enzymes that are involved in the cleavage of pesticide molecules, the factors/conditions that influence the survival of strains that are introduced into soil and the rate of the removal of pyrethroids are also discussed. This knowledge may be useful to optimize the environmental conditions of bioremediation and may be crucial for the effective removal of pyrethroids from polluted soils.

AB - Despite the development of on-farm anaerobic digestion as a process for making profitable use of animal by-products, factors leading to the inactivation of pathogenic bacteria during storage of digestates remain poorly described. Here, a microcosm approach was used to evaluate the persistence of three pathogenic bacteria (Salmonella enterica Derby, Campylobacter coli and Listeria monocytogenes) in digestates from farms, stored for later land spreading. Nine samples, including raw digestates, liquid fractions of digestate and composted digestates, were inoculated with each pathogen and maintained for 40 days at 24 degrees C. Concentrations of pathogens were monitored using culture and qPCR methods. The persistence of L. monocytogenes, detected up to 20 days after inoculation, was higher than that of Salmonella Derby, detected for 7-20 days, and of C. coli (not detected after 7 days). In some digestates, the concentration of the pathogens by qPCR assay was several orders of magnitude higher than the concentration of culturable cells, suggesting a potential loss of culturability and induction of Viable but Non-Culturable (VBNC) state. The potential VBNC state which was generally not observed in the same digestate for the three pathogens, occurred more frequently for C. coli and L. monocytogenes than for Salmonella Derby. Composting a digestate reduced the persistence of seeded L. monocytogenes but promoted the maintenance of Salmonella Derby. The effect of NH[Formula: see text]/NH3 on the culturability of C. coli and Salmonella Derby was also shown. The loss of culturability may be the underlying mechanism for the regrowth of pathogens. We have also demonstrated the importance of using molecular tools to monitor pathogens in environmental samples since culture methods may underestimate cell concentration. Our results underline the importance of considering VBNC cells when evaluating the sanitary effect of an anaerobic digestion process and the persistence of pathogens during the storage of digestates and subsequent land spreading. PMID- 27695453 TI - CMV-Specific CD8 T Cell Differentiation and Localization: Implications for Adoptive Therapies. AB - Human cytomegalovirus (HCMV) is a ubiquitous virus that causes chronic infection and, thus, is one of the most common infectious complications of immune suppression. Adoptive transfer of HCMV-specific T cells has emerged as an effective method to reduce the risk for HCMV infection and/or reactivation by restoring immunity in transplant recipients. However, the CMV-specific CD8+ T cell response is comprised of a heterogenous mixture of subsets with distinct functions and localization, and it is not clear if current adoptive immunotherapy protocols can reconstitute the full spectrum of CD8+ T cell immunity. The aim of this review is to briefly summarize the role of these T cell subsets in CMV immunity and to describe how current adoptive immunotherapy practices might affect their reconstitution in patients. The bulk of the CMV-specific CD8+ T cell population is made up of terminally differentiated effector T cells with immediate effector function and a short life span. Self-renewing memory T cells within the CMV-specific population retain the capacity to expand and differentiate upon challenge and are important for the long-term persistence of the CD8+ T cell response. Finally, mucosal organs, which are frequent sites of CMV reactivation, are primarily inhabited by tissue-resident memory T cells, which do not recirculate. Future work on adoptive transfer strategies may need to focus on striking a balance between the formation of these subsets to ensure the development of long lasting and protective immune responses that can access the organs affected by CMV disease. PMID- 27695454 TI - Induction of Hematopoietic Microchimerism by Gene-Modified BMT Elicits Antigen Specific B and T Cell Unresponsiveness toward Gene Therapy Products. AB - BACKGROUND: Gene therapy is a promising treatment option for hemophilia and other protein deficiencies. However, immune responses against the transgene product represent an obstacle to safe and effective gene therapy, urging for the implementation of tolerization strategies. Induction of a hematopoietic chimerism via bone marrow transplantation (BMT) is a potent means for inducing immunological tolerance in solid organ transplantation. OBJECTIVES: We reasoned, here, that the same viral vector could be used, first, to transduce BM cells for inducing chimerism-associated transgene-specific immune tolerance and, second, for correcting protein deficiencies by vector-mediated systemic production of the deficient coagulation factor. METHODS: Evaluation of strategies to induce B and T cell tolerance was performed using ex vivo gene transfer with lentiviral (LV) vectors encoding coagulation factor IX (FIX) or the SIINFEKL epitope of ovalbumin. Following induction of microchimerism via BMT, animals were challenged with in vivo gene transfer with LV vectors. RESULTS: The experimental approach prevented humoral immune response against FIX, resulting in persistence of therapeutic levels of circulating FIX, after LV-mediated gene transfer in vivo. In an ovalbumin model, we also demonstrated that this approach effectively tolerized the CD8+ T cell compartment in an antigen-specific manner. CONCLUSION: These results provide the proof-of-concept that inducing a microchimerism by gene modified BMT is a powerful tool to provide transgene-specific B and T cell tolerance in a gene therapy setting. PMID- 27695455 TI - Tissue-Specific Expression Patterns of MicroRNA during Acute Graft-versus-Host Disease in the Rat. AB - MicroRNAs (miRNA) have emerged as central regulators of diverse biological processes and contribute to driving pathology in several diseases. Acute graft versus-host disease (aGvHD) represents a major complication after allogeneic hematopoietic stem cell transplantation, caused by alloreactive donor T cells attacking host tissues leading to inflammation and tissue destruction. Changes in miRNA expression patterns occur during aGvHD, and we hypothesized that we could identify miRNA signatures in target tissues of aGvHD that may potentially help understand the underlying molecular pathology of the disease. We utilized a rat model of aGvHD with transplantation of fully MHC-mismatched T cell depleted bone marrow, followed by infusion of donor T cells. The expression pattern of 423 rat miRNAs was investigated in skin, gut, and lung tissues and intestinal T cells with the NanoString hybridization platform, in combination with validation by quantitative PCR. MHC-matched transplanted rats were included as controls. In the skin, upregulation of miR-34b and downregulation of miR-326 was observed, while in the intestines, we detected downregulation of miR-743b and a trend toward downregulation of miR-345-5p. Thus, tissue-specific expression patterns of miRNAs were observed. Neither miR-326 nor miR-743b has previously been associated with aGvHD. Moreover, we identified upregulation of miR-146a and miR-155 in skin tissue of rats suffering from aGvHD. Analysis of intestinal T cells indicated 23 miRNAs differentially regulated between aGvHD and controls. Two of these miRNAs were differentially expressed either in skin (miR-326) or in intestinal (miR-345 5p) tissue. Comparison of intestinal and peripheral blood T cells indicated common dysregulated expression of miR-99a, miR-223, miR-326, and miR-345-5p. Analysis of predicted gene targets for these miRNAs indicated potential targeting of an inflammatory network both in skin and in the intestines that may further regulate inflammatory cytokine production. In conclusion, comprehensive miRNA profiling in rats suffering from aGvHD demonstrate tissue-specific differences in the expression patterns of miRNA that may not be detected by profiling of peripheral blood T cells alone. These tissue-specific miRNAs may contribute to distinct pathologic mechanisms and could represent potential targets for therapy. PMID- 27695456 TI - Immunological Basis of Bone Marrow Failure after Allogeneic Hematopoietic Stem Cell Transplantation. AB - Bone marrow failure (BMF) syndromes are severe complications of allogeneic hematopoietic stem cell transplantation (allo-HSCT). In this paper, we distinguish two different entities, the graft failure (GF) and the poor graft function (PGF), and we review the current understanding of the interactions between the immune and hematopoietic compartments in these conditions. We first discuss how GF occurs as the result of classical alloreactive immune responses mediated by residual host cellular and humoral immunity persisting after conditioning and prevented by host and donor regulatory T cells. We next summarize the current knowledge about the contribution of inflammatory mediators to the development of PGF. In situations of chronic inflammation complicating allo-HSCT, such as graft-versus-host disease or infections, PGF seems to be essentially the result of a sustained impairment of hematopoietic stem cells (HSC) self-renewal and proliferation caused by inflammatory mediators, such as interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha, and of induction of apoptosis through the Fas/Fas ligand pathway. Interestingly, the production of inflammatory molecules leads to a non-MHC restricted, bystander inhibition of hematopoiesis, therefore, representing a promising target for immunological interventions. Finally, we discuss immune-mediated impairment of bone marrow microenvironment as a potential mechanism hampering hematopoietic recovery. Better understanding of immunological mechanisms responsible for BMF syndromes after allo-HSCT may lead to the development of more efficient immunotherapeutic interventions. PMID- 27695458 TI - Tomato phyE Is Required for Shade Avoidance in the Absence of phyB1 and phyB2. AB - The phytochrome (phy) family of red and far-red photoreceptors provides plants with critical information about their surrounding environment and can signal downstream developmental and physiological changes. Neighboring plants compete for limited light resources, and their presence is detected by the phytochrome photoreceptors as a reduced ratio of red: far-red light. One common response to shade is increased elongation of petioles and internodes to compete with their neighbors. While the phytochrome family, phyB in particular, has been well studied in Arabidopsis, information about the other phytochrome family members is limited, especially in sympodial crop plants such as tomato, that have a very different architecture from that of the model plant. To study the tomato phytochrome family we took advantage of several existing mutants and generated an artificial miRNA (amiRNA) line to target SlPHYE, the remaining phytochrome B subfamily member with no currently available mutant line. Here, we characterize internode elongation and shade avoidance phenotypes of the SlPHYE amiRNA line (PHYE amiRNA). In addition, higher order phytochrome subfamily B mutants were generated with the PHYE amiRNA line to investigate the role of SlphyE within the phyB subfamily. We find that the PHYE amiRNA line has no detectable phenotype on its own, however in higher order combinations with SlphyB1 and/or SlphyB2 there are notable defects in shade avoidance. Most notably, we find that the triple mutant combination of SlPHYE amiRNA, SlphyB1, and SlphyB2 has a phenotype that is much stronger than the SlphyB1 SlphyB2 double, showing constitutive shade avoidance and little to no response to shade. This indicates that SlphyE is required for the shade avoidance response in the absence of SlphyB1 and SlphyB2. PMID- 27695457 TI - Impact of Viral Infections on Hematopoiesis: From Beneficial to Detrimental Effects on Bone Marrow Output. AB - The ability of the bone marrow (BM) to generate copious amounts of blood cells required on a daily basis depends on a highly orchestrated process of proliferation and differentiation of hematopoietic stem and progenitor cells (HSPCs). This process can be rapidly adapted under stress conditions, such as infections, to meet the specific cellular needs of the immune response and the ensuing physiological changes. This requires a tight regulation in order to prevent either hematopoietic failure or transformation. Although adaptation to bacterial infections or systemic inflammation has been studied and reviewed in depth, specific alterations of hematopoiesis to viral infections have received less attention so far. Viruses constantly pose a significant health risk and demand an adequate, balanced response from our immune system, which also affects the BM. In fact, both the virus itself and the ensuing immune response can have a tremendous impact on the hematopoietic process. On one hand, this can be beneficial: it helps to boost the cellular response of the body to resolve the viral infection. But on the other hand, when the virus and the resulting antiviral response persist, the inflammatory feedback to the hematopoietic system will become chronic, which can be detrimental for a balanced BM output. Chronic viral infections frequently have clinical manifestations at the level of blood cell formation, and we summarize which viruses can lead to BM pathologies, like aplastic anemia, pancytopenia, hemophagocytic lymphohistiocytosis, lymphoproliferative disorders, and malignancies. Regarding the underlying mechanisms, we address specific effects of acute and chronic viral infections on blood cell production. As such, we distinguish four different levels in which this can occur: (1) direct viral infection of HSPCs, (2) viral recognition by HSPCs, (3) indirect effects on HSPCs by inflammatory mediators, and (4) the role of the BM microenvironment on hematopoiesis upon virus infection. In conclusion, this review provides a comprehensive overview on how viral infections can affect the formation of new blood cells, aiming to advance our understanding of the underlying cellular and molecular mechanisms to improve the treatment of BM failure in patients. PMID- 27695459 TI - OsPEX11, a Peroxisomal Biogenesis Factor 11, Contributes to Salt Stress Tolerance in Oryza sativa. AB - Peroxisomes are single membrane-bound organelles, whose basic enzymatic constituents are catalase and H2O2-producing flavin oxidases. Previous reports showed that peroxisome is involved in numerous processes including primary and secondary metabolism, plant development and abiotic stress responses. However, knowledge on the function of different peroxisome genes from rice and its regulatory roles in salt and other abiotic stresses is limited. Here, a novel prey protein, OsPEX11 (Os03g0302000), was screened and identified by yeast two hybrid and GST pull-down assays. Phenotypic analysis of OsPEX11 overexpression seedlings demonstrated that they had better tolerance to salt stress than wild type (WT) and OsPEX11-RNAi seedlings. Compared with WT and OsPEX11-RNAi seedlings, overexpression of OsPEX11 had lower level of lipid peroxidation, Na+/K+ ratio, higher activities of antioxidant enzymes (SOD, POD, and CAT) and proline accumulation. Furthermore, qPCR data suggested that OsPEX11 acted as a positive regulator of salt tolerance by reinforcing the expression of several well-known rice transporters (OsHKT2;1, OsHKT1;5, OsLti6a, OsLti6b, OsSOS1, OsNHX1, and OsAKT1) involved in Na+/K+ homeostasis in transgenic plants under salinity. Ultrastructural observations of OsPEX11-RNAi seedlings showed that they were less sensitive to salt stress than WT and overexpression lines. These results provide experimental evidence that OsPEX11 is an important gene implicated in Na+ and K+ regulation, and plays a critical role in salt stress tolerance by modulating the expression of cation transporters and antioxidant defense. Thus, OsPEX11 could be considered in transgenic breeding for improvement of salt stress tolerance in rice crop. PMID- 27695460 TI - EjODO1, a MYB Transcription Factor, Regulating Lignin Biosynthesis in Developing Loquat (Eriobotrya japonica) Fruit. AB - Lignin is important for plant secondary cell wall formation and participates in resistance to various biotic and abiotic stresses. Loquat undergoes lignification not only in vegetative tissues but also in flesh of postharvest fruit, which adversely affects consumer acceptance. Thus, researches on lignin biosynthesis and regulation are important to understand loquat fruit lignification. In loquat, a gene encoding an enzyme in the lignin biosynthesis pathway, Ej4CL1, was reported to be regulated by transcription factors, including EjMYB1, EjMYB2, EjMYB8, and EjAP2-1, knowledge of this process is still limited. With the aim of identifying novel transcriptional factors controlling lignin biosynthesis in loquat, the promoter of Ej4CL1 was utilized to screen a cDNA library by yeast one hybrid assay. A novel R2R3 MYB, named EjODO1, was identified. Real-time PCR analyses indicated that EjODO1 is highly expressed in lignified stems and roots. During fruit development, expression of EjODO1 decreased along with the reduction of lignin content and became undetectable in mature ripe fruit. Thus, EjODO1 is likely to be involved in lignification of vegetative organs and early fruit development but not in mature fruit or postharvest lignification. Dual-luciferase assay indicated that EjODO1 could trans-activate promoters of lignin biosynthesis genes, such as EjPAL1, Ej4CL1, and Ej4CL5 and transient overexpression of EjODO1 triggered lignin biosynthesis. These results indicate a role for EjODO1 in regulating lignin biosynthesis in loquat which is different from the previously characterized transcription factors. PMID- 27695461 TI - A High-Resolution InDel (Insertion-Deletion) Markers-Anchored Consensus Genetic Map Identifies Major QTLs Governing Pod Number and Seed Yield in Chickpea. AB - Development and large-scale genotyping of user-friendly informative genome/gene derived InDel markers in natural and mapping populations is vital for accelerating genomics-assisted breeding applications of chickpea with minimal resource expenses. The present investigation employed a high-throughput whole genome next-generation resequencing strategy in low and high pod number parental accessions and homozygous individuals constituting the bulks from each of two inter-specific mapping populations [(Pusa 1103 * ILWC 46) and (Pusa 256 * ILWC 46)] to develop non-erroneous InDel markers at a genome-wide scale. Comparing these high-quality genomic sequences, 82,360 InDel markers with reference to kabuli genome and 13,891 InDel markers exhibiting differentiation between low and high pod number parental accessions and bulks of aforementioned mapping populations were developed. These informative markers were structurally and functionally annotated in diverse coding and non-coding sequence components of genome/genes of kabuli chickpea. The functional significance of regulatory and coding (frameshift and large-effect mutations) InDel markers for establishing marker-trait linkages through association/genetic mapping was apparent. The markers detected a greater amplification (97%) and intra-specific polymorphic potential (58-87%) among a diverse panel of cultivated desi, kabuli, and wild accessions even by using a simpler cost-efficient agarose gel-based assay implicating their utility in large-scale genetic analysis especially in domesticated chickpea with narrow genetic base. Two high-density inter-specific genetic linkage maps generated using aforesaid mapping populations were integrated to construct a consensus 1479 InDel markers-anchored high-resolution (inter-marker distance: 0.66 cM) genetic map for efficient molecular mapping of major QTLs governing pod number and seed yield per plant in chickpea. Utilizing these high-density genetic maps as anchors, three major genomic regions harboring each of pod number and seed yield robust QTLs (15-28% phenotypic variation explained) were identified on chromosomes 2, 4, and 6. The integration of genetic and physical maps at these QTLs mapped on chromosomes scaled-down the long major QTL intervals into high-resolution short pod number and seed yield robust QTL physical intervals (0.89-2.94 Mb) which were essentially got validated in multiple genetic backgrounds of two chickpea mapping populations. The genome-wide InDel markers including natural allelic variants and genomic loci/genes delineated at major six especially in one colocalized novel congruent robust pod number and seed yield robust QTLs mapped on a high-density consensus genetic map were found most promising in chickpea. These functionally relevant molecular tags can drive marker-assisted genetic enhancement to develop high-yielding cultivars with increased seed/pod number and yield in chickpea. PMID- 27695462 TI - Impact of Wheat/Faba Bean Mixed Cropping or Rotation Systems on Soil Microbial Functionalities. AB - Cropping systems based on carefully designed species mixtures reveal many potential advantages in terms of enhancing crop productivity, reducing pest and diseases, and enhancing ecological services. Associating cereals and legume production either through intercropping or rotations might be a relevant strategy of producing both type of culture, while benefiting from combined nitrogen fixed by the legume through its symbiotic association with nitrogen-fixing bacteria, and from a better use of P and water through mycorrhizal associations. These practices also participate to the diversification of agricultural productions, enabling to secure the regularity of income returns across the seasonal and climatic uncertainties. In this context, we designed a field experiment aiming to estimate the 2 years impact of these practices on wheat yield and on soil microbial activities as estimated through Substrate Induced Respiration method and mycorrhizal soil infectivity (MSI) measurement. It is expected that understanding soil microbial functionalities in response to these agricultural practices might allows to target the best type of combination, in regard to crop productivity. We found that the tested cropping systems largely impacted soil microbial functionalities and MSI. Intercropping gave better results in terms of crop productivity than the rotation practice after two cropping seasons. Benefits resulting from intercrop should be highly linked with changes recorded on soil microbial functionalities. PMID- 27695463 TI - Variation in Host and Pathogen in the Neonectria/Malus Interaction; toward an Understanding of the Genetic Basis of Resistance to European Canker. AB - Apple canker caused by the phytopathogenic fungus Neonectria ditissima is an economically important disease, which has spread in recent years to almost all pome-producing regions of the world. N. ditissima is able to cross-infect a wide range of apple varieties and causes branch and trunk lesions, known as cankers. Most modern apple varieties are susceptible and in extreme cases suffer from high mortality (up to 50%) in the early phase of orchard establishment. There is no known race structure of the pathogen and the global level of genetic diversity of the pathogen population is unknown. Resistance breeding is underway in many global breeding programmes, but nevertheless, a total resistance to canker has not yet been demonstrated. Here we present preliminary data from a survey of the phylogenetic relationships between global isolates of N. ditissima which reveals only slight evidence for population structure. In addition we report the results of four rapid screening tests to assess the response to N. ditissima in different apple scion and rootstock varieties, which reveals abundant variation in resistance responses in both cultivar and rootstock material. Further seedling tests show that the segregation patterns of resistance and susceptibility vary widely between crosses. We discuss inconsistencies in test performance with field observations and discuss future research opportunities in this area. PMID- 27695464 TI - Co-ordination in Morphological Leaf Traits of Early Diverging Angiosperms Is Maintained Following Exposure to Experimental Palaeo-atmospheric Conditions of Sub-ambient O2 and Elevated CO2. AB - In order to be successful in a given environment a plant should invest in a vein network and stomatal distribution that ensures balance between both water supply and demand. Vein density (Dv) and stomatal density (SD) have been shown to be strongly positively correlated in response to a range of environmental variables in more recently evolved plant species, but the extent of this relationship has not been confirmed in earlier diverging plant lineages. In order to examine the effect of a changing atmosphere on the relationship between Dv and SD, five early diverging plant species representing two different reproductive plant grades were grown for 7 months in a palaeo-treatment comprising an O2:CO2 ratio that has occurred multiple times throughout plant evolutionary history. Results show a range of species-specific Dv and SD responses to the palaeo-treatment, however, we show that the strong relationship between Dv and SD under modern ambient atmospheric composition is maintained following exposure to the palaeo-treatment. This suggests strong inter-specific co-ordination between vein and stomatal traits for our study species even under relatively extreme environmental change. This co-ordination supports existing plant function proxies that use the distance between vein endings and stomata (Dm) to infer plant palaeo-physiology. PMID- 27695465 TI - Transcriptome Profiling of Petal Abscission Zone and Functional Analysis of an Aux/IAA Family Gene RhIAA16 Involved in Petal Shedding in Rose. AB - Roses are one of the most important cut flowers among ornamental plants. Rose flower longevity is largely dependent on the timing of petal shedding occurrence. To understand the molecular mechanism underlying petal abscission in rose, we performed transcriptome profiling of the petal abscission zone during petal shedding using Illumina technology. We identified a total of 2592 differentially transcribed genes (DTGs) during rose petal shedding. Gene ontology term enrichment and pathway analysis revealed that major biochemical pathways the DTGs were involved in included ethylene biosynthesis, starch degradation, superpathway of cytosolic glycolysis, pyruvate dehydrogenase and TCA cycle, photorespiration and the lactose degradation III pathway. This suggests that alterations in carbon metabolism are an important part of rose petal abscission. Among these DTGs, approximately 150 genes putatively encoding transcription factors were identified in rose abscission zone. These included zinc finger, WRKY, ERF, and Aux/IAA gene families, suggesting that petal abscission involves complex transcriptional reprogramming. Approximately 108 DTGs were related to hormone pathways, of which auxin and ethylene related DTGs were the largest groups including 52 and 41 genes, respectively. These also included 12 DTGs related to gibberellin and 6 DTGs in jasmonic acid pathway. Surprisingly, no DTGs involved in the biosynthesis/signaling of abscisic acid, cytokinin, brassinosteroid, and salicylic acid pathways were detected. Moreover, among DTGs related to auxin, we identified an Aux/IAA gene RhIAA16 that was up-regulated in response to petal shedding. Down-regulation of RhIAA16 by virus-induced gene silencing in rose promoted petal abscission, suggesting that RhIAA16 plays an important role in rose petal abscission. PMID- 27695466 TI - Expression of the Grape VqSTS21 Gene in Arabidopsis Confers Resistance to Osmotic Stress and Biotrophic Pathogens but Not Botrytis cinerea. AB - Stilbene synthase (STS) is a key gene in the biosynthesis of various stilbenoids, including resveratrol and its derivative glucosides (such as piceid), that has been shown to contribute to disease resistance in plants. However, the mechanism behind such a role has yet to be elucidated. Furthermore, the function of STS genes in osmotic stress tolerance remains unclear. As such, we sought to elucidate the role of STS genes in the defense against biotic and abiotic stress in the model plant Arabidopsis thaliana. Expression profiling of 31 VqSTS genes from Vitis quinquangularis revealed that VqSTS21 was up-regulated in response to powdery mildew (PM) infection. To provide a deeper understanding of the function of this gene, we cloned the full-length coding sequence of VqSTS21 and overexpressed it in Arabidopsis thaliana via Agrobacterium-mediated transformation. The resulting VqSTS21 Arabidopsis lines produced trans-piceid rather than resveratrol as their main stilbenoid product and exhibited improved disease resistance to PM and Pseudomonas syringae pv. tomato DC3000, but displayed increased susceptibility to Botrytis cinerea. In addition, transgenic Arabidopsis lines were found to confer tolerance to salt and drought stress from seed germination through plant maturity. Intriguingly, qPCR assays of defense related genes involved in salicylic acid, jasmonic acid, and abscisic acid induced signaling pathways in these transgenic lines suggested that VqSTS21 plays a role in various phytohormone-related pathways, providing insight into the mechanism behind VqSTS21-mediated resistance to biotic and abiotic stress. PMID- 27695467 TI - Sulfur Mediated Alleviation of Mn Toxicity in Polish Wheat Relates to Regulating Mn Allocation and Improving Antioxidant System. AB - Sulfur (S) is an essential macronutrient that has been proved to play an important role in regulating plant responses to various biotic and abiotic stresses. The present study was designed to investigate the effect of S status on polish wheat plant response to Mn toxicity. Results showed that Mn stress inhibited plant growth, disturbed photosynthesis and induced oxidative stress. In response to Mn stress, polish wheat plant activated several detoxification mechanisms to counteract Mn toxicity, including enhanced antioxidant defense system, increased Mn distribution in the cell wall and up-regulated genes involved in S assimilation. Moderate S application was found to alleviate Mn toxicity mainly by sequestering excess Mn into vacuoles, inhibiting Mn translocation from roots to shoots, stimulating activities of antioxidant enzymes and enhancing GSH production via up-regulating genes involved in S metabolism. However, application of high level S to Mn-stressed plants did not significantly alleviated Mn toxicity likely due to osmotic stress. In conclusion, moderate S application is beneficial to polish wheat plant against Mn toxicity, S exerts its effects via stimulating the antioxidant defense system and regulating the translocation and subcellular distribution of Mn, in which processes GSH plays an indispensable role. PMID- 27695470 TI - Aploneura lentisci (Homoptera: Aphididae) and Its Interactions with Fungal Endophytes in Perennial Ryegrass (Lolium perenne). AB - Aploneura lentisci Pass. is endemic to the Mediterranean region where it is holocyclic, forming galls on its primary host, Pistacia lentiscus and alternating over a 2-year period between Pistacia and secondary hosts, principally species of Gramineae. This aphid is widely distributed in Australia and New Zealand on the roots of the common forage grasses, ryegrass (Lolium spp.) and tall fescue (Schedonorus phoenix) where it exists as permanent, anholocyclic, parthenogenetic populations. Previous studies have indicated that infestations of A. lentisci significantly reduce plant growth and may account for differences in field performance of Lolium perenne infected with different strains of the fungal endophyte Epichloe festucae var. lolii. These obligate biotrophs protect their host grasses from herbivory via the production of alkaloids. To confirm the hypothesis that growth of L. perenne is associated with the effect of different endophyte strains on aphid populations, herbage and root growth were measured over time in two pot trials that compared three fungal endophyte strains with an endophyte-free control. In both pot trials, aphid numbers were lowest on plants infected with endophyte strain AR37 at all sampling times. In plants infected with a common toxic strain naturalized in New Zealand, aphid numbers overall were lower than on uninfected plants or those infected with strain AR1, but numbers did not always differ significantly from these treatments. Populations on AR1 infected plants were occasionally significantly higher than those on endophyte free. Cumulative foliar growth was reduced in AR1 and Nil treatments relative to AR37 in association with population differences of A. lentisci in both trials and root dry weight was reduced in one trial. In four Petri dish experiments survival of A. lentisci on plants infected with AR37 declined to low levels after an initial phase of up to 19 days during which time aphids fed and populations were similar to those on plants without endophyte. Aphids on AR37-infected plants became uncoordinated in their movement and developed tremors before dying suggesting a neurotoxin was responsible for their mortality. Results support the hypothesis that differences in A. lentisci populations due to endophyte infection status and strain affects plant growth. PMID- 27695469 TI - The Infection of Cucumber (Cucumis sativus L.) Roots by Meloidogyne incognita Alters the Expression of Actin-Depolymerizing Factor (ADF) Genes, Particularly in Association with Giant Cell Formation. AB - Cucumber (Cucumis sativus L.) is threatened by substantial yield losses due to the south root-knot nematode (Meloidogyne incognita). However, understanding of the molecular mechanisms underlying the process of nematode infection is still limited. In this study, we found that M. incognita infection affected the structure of cells in cucumber roots and treatment of the cytoskeleton inhibitor (cytochalasin D) reduced root-knot nematode (RKN) parasitism. It is known that Actin-Depolymerizing Factor (ADF) affects cell structure, as well as the organization of the cytoskeleton. To address the hypothesis that nematode-induced abnormal cell structures and cytoskeletal rearrangements might be mediated by the ADF genes, we identified and characterized eight cucumber ADF (CsADF) genes. Phylogenetic analysis showed that the cucumber ADF gene family is grouped into four ancient subclasses. Expression analysis revealed that CsADF1, CsADF2-1, CsADF2-2, CsADF2-3 (Subclass I), and CsADF6 (Subclass III) have higher transcript levels than CsADF7-1, CsADF7-2 (Subclass II genes), and CsADF5 (Subclass IV) in roots. Members of subclass I genes (CsADF1, CsADF2-1, CsADF2-2, and CsADF2-3), with the exception of CsADF2-1, exhibited a induction of expression in roots 14 days after their inoculation (DAI) with nematodes. However, the expression of subclass II genes (CsADF7-1 and CsADF7-2) showed no significant change after inoculation. The transcript levels of CsADF6 (Subclass III) showed a specific induction at 21 DAI, while CsADF5 (Subclass IV) was weakly expressed in roots, but was strongly up-regulated as early as 7 DAI. In addition, treatment of roots with cytochalasin D caused an approximately 2-fold down-regulation of the CsADF genes in the treated plants.

AB - Plant cell vacuoles occupy up to 90% of the cell volume and, beyond their physiological function, are constantly subjected to water and solute exchange. The osmotic flow and vacuole volume dynamics relies on the vacuole membrane -the tonoplast- and its capacity to regulate its permeability to both water and solutes. The osmotic permeability coefficient (Pf ) is the parameter that better characterizes the water transport when submitted to an osmotic gradient. Usually, Pf determinations are made in vitro from the initial rate of volume change, when a fast (almost instantaneous) osmolality change occurs. When aquaporins are present, it is accepted that initial volume changes are only due to water movements. However, in living cells osmotic changes are not necessarily abrupt but gradually imposed. Under these conditions, water flux might not be the only relevant driving force shaping the vacuole volume response. In this study, we quantitatively investigated volume dynamics of isolated Beta vulgaris root vacuoles under progressively applied osmotic gradients at different pH, a condition that modifies the tonoplast Pf . We followed the vacuole volume changes while simultaneously determining the external osmolality time-courses and analyzing these data with mathematical modeling. Our findings indicate that vacuole volume changes, under progressively applied osmotic gradients, would not depend on the membrane elastic properties, nor on the non-osmotic volume of the vacuole, but on water and solute fluxes across the tonoplast. We found that the volume of the vacuole at the steady state is determined by the ratio of water to solute permeabilites (Pf /Ps ), which in turn is ruled by pH. The dependence of the permeability ratio on pH can be interpreted in terms of the degree of aquaporin inhibition and the consequently solute transport modulation. This is relevant in many plant organs such as root, leaves, cotyledons, or stems that perform extensive rhythmic growth movements, which very likely involve considerable cell volume changes within seconds to hours.

AB - To determine if host plant abundance determined the size of clover root weevil (CRW) Sitona obsoletus larval populations, a study was conducted over 4 years in plots sown in ryegrass (Lolium perenne) (cv. Nui) sown at either 6 or 30 kg/ha and white clover (Trifolium repens) sown at a uniform rate of 8 kg/ha. This provided a range of % white clover content to investigate CRW population establishment and impacts on white clover survival. Larval sampling was carried out in spring (October) when larval densities are near their spring peak at Lincoln (Canterbury, New Zealand) with % clover measured in autumn (April) and spring (September) of each year. Overall, mean larval densities measured in spring 2012-2015 were 310, 38, 59, and 31 larvae m-2, respectively. There was a significant decline in larval populations between 2012 and 2013, but spring populations were relatively uniform thereafter. The mean % white clover measured in autumns of 2012 to 2015 was 17, 10, 3, and 11%, respectively. In comparison, mean spring % white clover from 2012 to 2015, averaged c. 5% each year. Analysis relating spring (October) larval populations to % white clover measured in each plot in autumn (April) found the 2012 larval population to be statistically significantly larger in the ryegrass 6 kg/ha plots than 30 kg/ha plots. Thereafter, sowing rate had no significant effect on larval populations. From 2013 to 2015, spring larval populations had a negative relationship with the previous autumn % white clover with the relationship highly significant for the 2014 data. When CRW larval populations in spring 2013 to 2015 were predicted from the 2013 to 2015 autumn % white clover, respectively, based on their positive relationship in 2012, the predicted densities were substantially larger than those observed. Conversely, when 2015 spring larval data and % clover was regressed against 2012-2014 larval populations, observed densities tended to be higher than predicted, but the numbers came closer to predicted for the 2013 and 2014 populations. These differences are attributed to a CRW population decline that was not accounted by % white clover changes, the CRW decline most likely due to biological control by the Braconid endoparasitoid Microctonus aethiopoides, which showed incremental increases in parasitism between 2012 and 2015, which in 2015 averaged 93%.

AB - Inorganic phosphate is one of key macronutrients essential for plant growth. The acquisition and distribution of phosphate are mediated by phosphate transporters functioning in various physiological and biochemical processes. In the present study, we comprehensively evaluated the phosphate transporter (PHT) gene family in the latest release of the Populus trichocarpa genome (version 3.0; Phytozome 11.0) and a total of 42 PHT genes were identified which formed five clusters: PHT1, PHT2, PHT3, PHT4, and PHO. Among the 42 PHT genes, 41 were localized to 15 Populus chromosomes. Analysis of these genes led to identification of 5-14 transmembrane segments, most of which were conserved within the same cluster. We identified 234 putative cis elements in the 2-kb upstream regions of the 42 PHT genes, many of which are related to development, stress, or hormone. Tissue specific expression analysis of the 42 PtPHT genes revealed that 25 were highly expressed in the roots of P. tremula, suggesting that most of them might be involved in Pi uptake. Some PtPHT genes were highly expressed in more than six of the twelve investigated tissues of P. tremula, while the expression of a few of them was very low in all investigated tissues. In addition, the expression of the PtPHT genes was verified by quantitative real-time PCR in four tissues of P. simonii. Transcripts of 7 PtPHT genes were detected in all four tested tissues of P. simonii. Most PtPHT genes were expressed in the roots of P. simonii at high levels. Further, PtPHT1.2 and PtPHO9 expression was increased under drought conditions, irrespective of the phosphate levels. In particular, PtPHT1.2 expression was significantly induced by approximately 90-fold. However, the transcriptional changes of some PtPHT genes under drought stress were highly dependent on the phosphate levels. These results will aid in elucidation of the functions of PtPHT in the growth, development, and stress response of the poplar plant.

AB - Mitogen-activated protein kinase (MAPK) cascades are the conserved and universal signal transduction modules in all eukaryotes, which play the vital roles in plant growth, development, and in response to multiple stresses. In this study, we used bioinformatics methods to identify 86 MAPKKK protein encoded by 73 MAPKKK genes in Brachypodium. Phylogenetic analysis of MAPKKK family from Arabidopsis, rice, and Brachypodium has classified them into three subfamilies, of which 28 belonged to MEKK, 52 to Raf, and 6 to ZIK subfamily, respectively. Conserved protein motif, exon-intron organization, and splicing intron phase in kinase domains supported the evolutionary relationships inferred from the phylogenetic analysis. And gene duplication analysis suggested the chromosomal segment duplication happened before the divergence of the rice and Brachypodium, while all of three tandem duplicated gene pairs happened after their divergence. We further demonstrated that the MAPKKKs have evolved under strong purifying selection, implying the conservation of them. The splicing transcripts expression analysis showed that the splicesome translating longest protein tended to be adopted. Furthermore, the expression analysis of BdMAPKKKs in different organs and development stages as well as heat, virus and drought stresses revealed that the MAPKKK genes were involved in various signaling pathways. And the circadian analysis suggested there were 41 MAPKKK genes in Brachypodium showing cycled expression in at least one condition, of which seven MAPKKK genes expressed in all conditions and the promoter analysis indicated these genes possessed many cis acting regulatory elements involved in circadian and light response. Finally, the co-expression network of MAPK, MAPKK, and MAPKKK in Brachypodium was constructed using 144 microarray and RNA-seq datasets, and ten potential MAPK cascades pathway were predicted. To conclude, our study provided the important information for evolutionary and functional characterization of MAPKKK family in Brachypodium, which will facilitate the functional analysis of BdMAPKKK genes, and also will facilitate better understanding the MAPK signal pathway in Brachypodium and beyond.

AB - Soil salinity is a serious problem worldwide that reduces agricultural productivity. Trichoderma longibrachiatum T6 (T6) has been shown to promote wheat growth and induce plant resistance to parasitic nematodes, but whether the plant growth-promoting fungi T6 can enhance plant tolerance to salt stress is unknown. Here, we determined the effect of plant-growth-promoting fungi T6 on wheat seedlings' growth and development under salt stress, and investigated the role of T6 in inducing the resistance to NaCl stress at physiological, biochemical, and molecular levels. Wheat seedlings were inoculated with the strain of T6 and then compared with non-inoculated controls. Shoot height, root length, and shoot and root weights were measured on 15 days old wheat seedlings grown either under 150 mM NaCl or in a controlled setting without any NaCl. A number of colonies were re isolated from the roots of wheat seedlings under salt stress. The relative water content in the leaves and roots, chlorophyll content, and root activity were significantly increased, and the accumulation of proline content in leaves was markedly accelerated with the plant growth parameters, but the content of leaf malondialdehyde under saline condition was significantly decreased. The antioxidant enzymes-superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in wheat seedlings were increased by 29, 39, and 19%, respectively, with the application of the strain of T6 under salt stress; the relative expression of SOD, POD, and CAT genes in these wheat seedlings were significantly up-regulated. Our results indicated that the strain of T6 ameliorated the adverse effects significantly, protecting the seedlings from salt stress during their growth period. The possible mechanisms by which T6 suppresses the negative effect of NaCl stress on wheat seedling growth may be due to the improvement of the antioxidative defense system and gene expression in the stressed wheat plants. PMID- 27695476 TI - SRBreak: A Read-Depth and Split-Read Framework to Identify Breakpoints of Different Events Inside Simple Copy-Number Variable Regions. AB - Copy-number variation (CNV) has been associated with increased risk of complex diseases. High-throughput sequencing (HTS) technologies facilitate the detection of copy-number variable regions (CNVRs) and their breakpoints. This helps in understanding genome structure as well as their evolution process. Various approaches have been proposed for detecting CNV breakpoints, but currently it is still challenging for tools based on a single analysis method to identify breakpoints of CNVs. It has been shown, however, that pipelines which integrate multiple approaches are able to report more reliable breakpoints. Here, based on HTS data, we have developed a pipeline to identify approximate breakpoints (+/-10 bp) relating to different ancestral events within a specific CNVR. The pipeline combines read-depth and split-read information to infer breakpoints, using information from multiple samples to allow an imputation approach to be taken. The main steps involve using a normal mixture model to cluster samples into different groups, followed by simple kernel-based approaches to maximize information obtained from read-depth and split-read approaches, after which common breakpoints of groups are inferred. The pipeline uses split-read information directly from CIGAR strings of BAM files, without using a re alignment step. On simulated data sets, it was able to report breakpoints for very low-coverage samples including those for which only single-end reads were available. When applied to three loci from existing human resequencing data sets (NEGR1, LCE3, IRGM) the pipeline obtained good concordance with results from the 1000 Genomes Project (92, 100, and 82%, respectively). The package is available at https://github.com/hoangtn/SRBreak, and also as a docker-based application at https://registry.hub.docker.com/u/hoangtn/srbreak/. PMID- 27695478 TI - In Papyro Comparison of TMM (edgeR), RLE (DESeq2), and MRN Normalization Methods for a Simple Two-Conditions-Without-Replicates RNA-Seq Experimental Design. AB - In the past 5 years, RNA-Seq has become a powerful tool in transcriptome analysis even though computational methods dedicated to the analysis of high-throughput sequencing data are yet to be standardized. It is, however, now commonly accepted that the choice of a normalization procedure is an important step in such a process, for example in differential gene expression analysis. The present article highlights the similarities between three normalization methods: TMM from edgeR R package, RLE from DESeq2 R package, and MRN. Both TMM and DESeq2 are widely used for differential gene expression analysis. This paper introduces properties that show when these three methods will give exactly the same results. These properties are proven mathematically and illustrated by performing in silico calculations on a given RNA-Seq data set. PMID- 27695479 TI - Global environmental change: local perceptions, understandings, and explanations. AB - Global environmental change (GEC) is an increasingly discussed phenomenon in the scientific literature as evidence of its presence and impacts continues to grow. Yet, while the documentation of GEC is becoming more readily available, local perceptions of GEC- particularly in small-scale societies-and preferences about how to deal with it, are still largely overlooked. Local knowledge and perceptions of GEC are important in that agents make decisions (including on natural resource management) based on individual perceptions. We carried out a systematic literature review that aims to provide an exhaustive state-of-the-art of the degree to and manner in which the study of local perceptions of change are being addressed in GEC research. We reviewed 126 articles found in peer-reviewed journals (between 1998 and 2014) that address local perceptions of GEC. We used three particular lenses of analysis that are known to influence local perceptions, namely (i) cognition, (ii) culture and knowledge, and (iii) possibilities for adaptation.We present our findings on the geographical distribution of the current research, the most common changes reported, perceived drivers and impacts of change, and local explanations and evaluations of change and impacts. Overall, we found the studies to be geographically biased, lacking methodological reporting, mostly theory based with little primary data, and lacking of indepth analysis of the psychological and ontological influences in perception and implications for adaptation. We provide recommendations for future GEC research and propose the development of a "meta-language" around adaptation, perception, and mediation to encourage a greater appreciation and understanding of the diversity around these phenomena across multiple scales, and improved codesign and facilitation of locally relevant adaptation and mitigation strategies. PMID- 27695477 TI - Differential Protein Distribution between the Nucleus and Mitochondria: Implications in Aging. AB - The coordination of nuclear and mitochondrial genomes plays a pivotal role in maintenance of mitochondrial biogenesis and functionality during stress and aging. Environmental and cellular inputs signal to nucleus and/or mitochondria to trigger interorganellar compensatory responses. Loss of this tightly orchestrated coordination results in loss of cellular homeostasis and underlies various pathologies and age-related diseases. Several signaling cascades that govern interorganellar communication have been revealed up to now, and have been classified as part of the anterograde (nucleus to mitochondria) or retrograde (mitochondrial to nucleus) response. Many of these molecular pathways rely on the dual distribution of nuclear or mitochondrial components under basal or stress conditions. These dually localized components usually engage in specific tasks in their primary organelle of function, whilst upon cellular stimuli, they appear in the other organelle where they engage in the same or a different task, triggering a compensatory stress response. In this review, we focus on protein factors distributed between the nucleus and mitochondria and activated to exert their functions upon basal or stress conditions. We further discuss implications of bi organellar targeting in the context of aging. PMID- 27695481 TI - Protective effects of hesperidin in experimental testicular ischemia/reperfusion injury in rats. AB - INTRODUCTION: In this study, we aimed to determine the protective effects of hesperidin, a citrus flavonoid, in a model of testicular ischemia/reperfusion injury in rats. MATERIAL AND METHODS: Forty-two pubertal male Wistar-Albino rats were divided into six groups: group 1 - control; group 2 - 50 mg/kg hesperidin (low dose hesperidin) used without torsion (LH group); group 3 - 100 mg/kg hesperidin without torsion (HH group); group 4 - torsion/detorsion group (T/D); group 5 - T/D + 50 mg/kg hesperidin treatment group (T/D + LH); and group 6 - T/D + 100 mg/kg hesperidin treatment group (T/D + HH). Hesperidin was given to the treatment groups 30 min before detorsion. After the fourth hour of reperfusion, orchiectomy was performed on the rats under anesthesia. The tissue samples were examined histologically and biochemically. RESULTS: In the T/D group testicular malondialdehyde (MDA) levels were increased significantly (p < 0.001) whereas superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) levels were decreased compared to the control and other groups. However, hesperidin caused the effect of T/D to become closer to normal biochemical values. In addition, the histological examinations showed that T/D caused damage in the testis but hesperidin reduced this effect. The effects of hesperidin were found to be dose dependent. Thus, applying high doses would generate greater therapeutic effects. CONCLUSIONS: In a rat testicular T/D model we observed biochemical and histological damage due to ischemia. However, high and low dose applications of hesperidin were shown to have protective effects against this damage. Therefore, the aforementioned citrus flavonoid may provide positive results in cases of testicular torsion. PMID- 27695480 TI - Meroxest improves the prognosis of immunocompetent C57BL/6 mice with allografts of E0771 mouse breast tumor cells. AB - INTRODUCTION: Recently, we have reported the antitumor properties of a new family of synthetic merosesquiterpenes, among which meroxest is highlighted, since it has high activity and specificity for ER+ breast cancer cells. In this paper, we characterize allografts of ER+ E0771 mouse breast tumor cells in immunocompetent C57BL/6 mice, and also analyze the effect of meroxest on the prognosis of the disease. MATERIAL AND METHODS: Twenty female C57BL/6 mice were injected with 106 E0771 cells. Once the tumors reached the appropriate size, the mice were divided into two groups, one control and another treated orally with 15 mg/kg of meroxest. After 20 days, tumor samples were taken for histopathological study and for determination of the expression of the prognostic markers Ki67 and vascular endothelial growth factor (VEGF) by immunofluorescence. RESULTS: In sections stained with hematoxylin-eosin, we observed that tumors have a well-defined capsule enclosing E0771 tumor cells. The central area of tumors contains necrotic regions with leukocyte infiltration. Meroxest treatment significantly reduces tumor size (68%, p < 0.05), induces changes in its structure, decreases the degree of leukocyte infiltration, and significantly reduces the expression of Ki67 (33%, p < 0.05) and VEGF (82%, p < 0.05). CONCLUSIONS: Meroxest improves the prognosis of mice since it reduces leukocyte infiltration, and decreases the expression of Ki67 and VEGF markers. Consequently, the merosesquiterpene could become a useful antiangiogenic drug in the treatment of breast cancer. These results encourage us to deepen the study of meroxest, in order to find more evidence that supports the convenience of its evaluation in a clinical study or trial. PMID- 27695482 TI - The effects of treadmill exercise on penicillin-induced epileptiform activity. AB - INTRODUCTION: The aim of this study was to evaluate the effects of short-, moderate- and long-duration treadmill exercise (15, 30 and 60 min) on the mean frequency and amplitude of penicillin-induced epileptiform activity in rats. MATERIAL AND METHODS: In this study, 32 rats were assigned to 15, 30, and 60 min running exercise groups and the control group, each consisting of 8 rats. According to the specified protocol, the rats were submitted to running exercises at the same hour of each day for 90 days. After the exercise program, the rats were administered (500 IU/2.5 ul) of penicillin into the left cortex by the microinjection method. An electrocorticogram (ECoG) recording was performed for 3 h using a data acquisition system. The frequency and the amplitude of the recordings were analyzed. RESULTS: Short-duration treadmill exercise (15 min) caused a decrease in the frequency of penicillin-induced epileptiform activity at 70 min after penicillin injection (p < 0.001). The mean frequency of epileptiform activity decreased at 90 min after penicillin injection in the 30 and 60 min treadmill exercise groups (p < 0.01). The mean amplitude of epileptiform activity was not changed in any of the exercise groups compared to the control (p > 0.05). CONCLUSIONS: The results of the present study demonstrate for the first time that short-, moderate- and long-duration treadmill exercises decreased the frequency of penicillin-induced epileptiform activity. These findings may contribute to improving the quality of life in epileptic patients. PMID- 27695484 TI - NLRP3 inflammasome: a novel link between lipoproteins and atherosclerosis. AB - INTRODUCTION: Pattern recognition receptor-mediated signaling pathways have recently been elucidated to bridge the innate immune system and atherosclerosis. NLRP3 is a member of the NLR family. Upon activation, it initiates IL-1beta and IL-18 processing, a key step in the inflammatory process of atherosclerosis. MATERIAL AND METHODS: We used three different types of lipoproteins, ox-LDL, ox HDL, and HDL, in Thp-1 at the concentration of 50 mg/l, 100 mg/l, and 150 mg/l respectively. Using real-time polymerase chain reaction and western blot, ELISA detected the expression of NLRP3 and downstream cytokines. NLRP3 siRNA was constructed to down-regulate expression of the NLRP3 gene via the RNA interference technique. 150 mg/l of ox-LDL, ox-HDL and HDL was added to the Thp-1 cell line respectively. We observed the changes in the expression of caspase-1, IL-1beta and IL-18 when the NLRP3 gene was down-regulated. RESULTS: Ox-LDL and ox HDL addition not only increases the expression of NLRP3, but also activates the NLRP3 downstream cytokines and caspase-1 and induces IL-1beta and IL-18 secretion. Moreover, the effects of activation and induction are shown to have a dose-dependent manner. Expression of NLRP3 and its downstream inflammatory cytokines is reduced in the presence of HDL (p < 0.05). Furthermore, our data demonstrated that NLRP3 siRNA downregulates NLRP3 expression in mononuclear cells, thus leading to a dramatic reduction in the expression of caspase-1, IL 1beta and IL-18 (p < 0.05). CONCLUSIONS: The data suggest that activation of the NLRP3 inflammasome is a critical step in caspase-1 activation and IL-1beta and IL 18 secretion. Interference with the NLRP3 inflammasome can significantly inhibit the generation of cytokines, thus impeding the pathogenesis of inflammation. PMID- 27695483 TI - Effect of a local, one time, low-dose injection of zoledronic acid on titanium implant osseointegration in ovariectomized rats. AB - INTRODUCTION: Local application of bisphosphonates has been proven to be safer than systemic administration to promote implant fixation. The objective of this study was to introduce such a simple, convenient and efficient method to enhance titanium (Ti) implant osseointegration in ovariectomized (OVX) rats. MATERIAL AND METHODS: Twenty female Sprague-Dawley rats sequentially underwent bilateral ovariectomy and tibia implantation, and injection of 30 ug/implant zoledronic acid (ZOL) at the site of implantation was performed. At the end of the study, the tibiae, mandibles, femurs and vertebrae were harvested for dual energy X-ray absorptiometry, histology and micro-computed tomography examination. RESULTS: Ovariectomized rats showed poor bone density, bone mass and trabecular microstructure. OVX + ZOL rats were characterized by significantly improved peri implant bone area (1.72-fold), bone contact (2.30-fold), bone mineral density (1.57-fold) and bone mineral content (1.67-fold), as well as moderately increased bone volume to total volume ratio (1.34-fold), percentage osteointegration (1.54 fold), connectivity density (1.45-fold), and trabecular number (1.43-fold), but decreased trabecular separation (57.69%) when compared with the control levels (p < 0.05). No histological signs of jaw osteonecrosis were observed in the rats treated with ZOL, and there was no significant difference between the OVX group and OVX + ZOL group in the bone mass of the mandible, femur and 5th lumbar vertebra (p > 0.05). In addition, the overproduction of osteoporosis-induced advanced glycation end-products (AGEs) was completely prevented by local treatment with 30 ug/implant ZOL. CONCLUSIONS: A local, one time, low-dose injection of ZOL at the site of implantation is able to promote the osseointegration of Ti implants following postmenopausal osteoporosis, and this action may be partly mediated by inhibition of the osteoporosis-induced AGE overproduction in the bone marrow.

AB - INTRODUCTION: Cardiovascular diseases are positively correlated with periodontal disease. However, the molecular mechanisms linking atherosclerosis and periodontal infection are not clear. This study aimed to determine whether Porphyromonas gingivalis lipopolysaccharide (Pg-LPS) altered the expression of genes regulating cholesterol metabolism in macrophages in the presence of low density lipoprotein (LDL). MATERIAL AND METHODS: THP-1-derived macrophages were exposed to different concentrations (0.1, 1, 10 ug/ml) of LPS in the presence of 50 ug/ml native LDL. Macrophages were also incubated with 1 ug/ml LPS for varying times (0, 24, 48, or 72 h) in the presence of native LDL. Foam cell formation was determined by oil red O staining and cholesterol content quantification. CD36, lectin-like oxidized LDL receptor-1 (LOX-1), ATP-binding cassette G1 (ABCG1), and acetyl CoA acyltransferase 1 (ACAT1) expression levels were measured by western blot and qRT-PCR. RESULTS: Foam cell formation was induced in a time- and concentration-dependent manner as assessed by both morphological and biochemical criteria. Pg-LPS caused downregulation of CD36 and ABCG1 but upregulation of ACAT1, while LOX-1 expression was not affected (p = 0.137). CONCLUSIONS: Pg-LPS appears to be an important link in the development of atherosclerosis by mechanisms targeting cholesterol homeostasis, namely, excess cholesterol ester formation via ACAT1 and reduced cellular cholesterol efflux via ABCG1. PMID- 27695486 TI - Expression of candidate genes associated with obesity in peripheral white blood cells of Mexican children. AB - INTRODUCTION: Obesity is a chronic, complex, and multifactorial disease, characterized by excess body fat. Diverse studies of the human genome have led to the identification of susceptibility genes that contribute to obesity. However, relatively few studies have addressed specifically the association between the level of expression of these genes and obesity. MATERIAL AND METHODS: We studied 160 healthy and obese unrelated Mexican children aged 6 to 14 years. We measured the transcriptional expression of 20 genes associated with obesity, in addition to the biochemical parameters, in peripheral white blood cells. The detection of mRNA levels was performed using the OpenArray Real-Time PCR System (Applied Biosystems). RESULTS: Obese children exhibited higher values of fasting glucose (p = 0.034), fasting insulin (p = 0.004), low-density lipoprotein (p = 0.006), triglycerides (p < 0.001), systolic blood pressure and diastolic blood pressure (p < 0.001), and lower values of high-density lipoprotein (p < 0.001) compared to lean children. Analysis of transcriptional expression data showed a difference for ADRB1 (p = 0.0297), ADIPOR1 (p = 0.0317), GHRL (p = 0.0060) and FTO (p = 0.0348) genes. CONCLUSIONS: Our results suggest that changes in the expression level of the studied genes are involved in biological processes implicated in the development of childhood obesity. Our study contributes new perspectives for a better understanding of biological processes involved in obesity. The protocol was approved by the National Committee and Ethical Committee Board from the Mexican Social Security Institute (IMSS) (IMSS FIS/IMSS/PRIO/10/011). PMID- 27695487 TI - Increased chitotriosidase activity in plasma of patients with type 2 diabetes. AB - INTRODUCTION: Chitotriosidase (CHIT1) is a chitinolytic enzyme involved mainly in the immune and inflammatory response. It shows increased activity in many pathologies, including in newly diagnosed type 2 diabetes (T2D). This study aimed to investigate this enzyme's activity in plasma of patients with ongoing T2D and indicate factors related to the increased activity of this enzyme. MATERIAL AND METHODS: Ninety-one patients and 46 control subjects without abnormalities in carbohydrate metabolism and inflammatory states were enrolled in the study. Plasma CHIT1 activity was measured by a spectrofluorometric method. Routine laboratory parameters such as blood glucose, total cholesterol and HDL fraction, triglyceride, glycated hemoglobin, white blood cell count and C-reactive protein were measured by standard methods. RESULTS: We found that the chitotriosidase activity was significantly higher (p < 0.001) in type 2 diabetic patients and positively associated with parameters of glycemic control (levels of glucose and glycated hemoglobin) and blood pressure. Plasma glucose level and systolic blood pressure were independent determinants of increased CHIT1 activity in T2D patients, even after adjustment for disease duration, body mass index, parameters of inflammation and lipid metabolism. We also found that increased CHIT1 activity was associated with occurrence of diabetic angiopathies. CONCLUSIONS: This investigation indicates a possible role of chitotriosidase in the course of T2D, especially in relation to development of diabetic angiopathies. PMID- 27695488 TI - PROGENS-HbA1c study: safety and effectiveness of premixed recombinant human insulin (Gensulin M30). AB - INTRODUCTION: Insulin analogues have gained widespread popularity. However, in many countries the use of these drugs is limited by their relatively high cost, so there is still a need for more cost-effective human insulin therapies. The aim of the study was to assess the effectiveness and safety of the premixed recombinant human insulin (rhuI) Gensulin M30 in a real-life setting. MATERIAL AND METHODS: The study group consisted of 4257 patients (2196 female, 2061 male) with type 2 diabetes, aged 63.7 +/-9.4, with body mass index (BMI) 30.3 +/-4.5 kg/m2 and diabetes duration 9 +/-5.5 years. All patients were treated with premixed rhuI Gensulin M30. In 91.7% of patients, insulin was used in combination with metformin. In 3.7% of patients, it was used with sulphonylureas. The patients were observed for a period of 6 months. RESULTS: The total insulin dose on visit 1 was 36.1 +/-18.7 U (0.42 +/-0.22 U/kg), and by the end of the study it reached 40.3 +/-18.9 U (0.48 +/-0.22 U/kg). A significant, continuous decrease of the levels of glycated hemoglobin (HbA1c), along with fasting and postprandial plasma glucose, was observed during the study period. The frequency of hypoglycemia increased slightly during the study, although these figures remained low, especially with regard to severe hypoglycemic episodes (0.02 episodes/patient/year). The lowest number of hypoglycemic episodes occurred in patients treated with insulin and metformin, while the highest number of episodes was observed in patients treated with insulin alone. No weight changes were noted in the patients during the study. CONCLUSIONS: This study shows rhuI Gensulin M30 to be effective and safe in a real-life setting. PMID- 27695489 TI - The effect of hyperoxia on central blood pressure in healthy subjects. AB - INTRODUCTION: Hyperoxia increases total peripheral resistance by acting locally but also inhibits the activity of carotid body chemoreceptors. We studied the effect of hyperoxia on central pressure in normotensive subjects. MATERIAL AND METHODS: Medical air followed by 100% oxygen was provided to 19 subjects (12/7 female/male, age 28.2 +/-1.1 years) for 15 min through a non-rebreather mask. Central blood pressure was then measured using applanation tonometry. RESULTS: After the first 2 min of hyperoxia, heart rate decreased significantly (65 +/-2.6 beats/min vs. 61 +/-2.1 beats/min, p = 0.0002). Peripheral and central blood pressure remained unchanged, while hemoglobin oxygen saturation and subendocardial viability ratio index increased (97 +/-0.4% vs. 99 +/-0.2%, p = 0.03; 168 +/-8.4% vs. 180 +/-8.2%, p = 0.009). After 15 min of 100% oxygen ventilation, heart rate and peripheral and central blood pressures remained unchanged from the first 2 min. The augmentation index, augmentation pressure and ejection duration increased as compared to baseline values and those obtained at 2 min (-5.1 +/-2.9% vs. -1.2 +/-2.6%, p = 0.005 and -4.6 +/-2.7% vs. -1.2 +/ 2.6%, p = 0.0015; -1.3 +/-0.7 mm Hg vs. -0.2 +/-1.2 mm Hg, p = 0.003 and -1.1 +/ 0.7 mm Hg vs. -0.2 +/-1.2 mm Hg, p = 0.012; 323 +/-3.6 ms vs. 330 +/-3.5 ms, p = 0.0002 and 326 +/-3.5 ms vs. 330 +/-3.5 ms, p = 0.021, respectively). CONCLUSIONS: The present study shows that hyperoxia does not affect central blood pressure in young healthy subjects and may improve myocardial blood supply estimated indirectly from applanation tonometry.

AB - INTRODUCTION: Previously, we have demonstrated that significant proportions of patients with various cardiovascular diseases have active tissue factor and active factor XIa in their plasma. In the current study, we evaluated active tissue factor and active factors (F)XI and FIX in plasma from patients with atrial fibrillation. MATERIAL AND METHODS: In 110 consecutive patients with permanent atrial fibrillation receiving warfarin, we determined active tissue factor, together with plasma FIXa and FXIa, using clotting assays by measuring the response to inhibitory monoclonal antibodies. RESULTS: Sixteen (14.5%) patients had detectable active tissue factor and active FXIa, including 11 subjects with both factors, while FIXa was observed in 28 (25.7%) patients. The three positive groups did not differ from the patients without these factors with regard to demographic and clinical characteristics. Von Willebrand factor was higher in the active tissue factor-positive group (p < 0.0001) and FXIa-positive group (p = 0.0037). Individuals positive for active tissue factor and FXIa had higher plasma interleukin-6 levels (p = 0.0014 and 0.0322, respectively). The presence of active tissue factor, FXIa and FIXa in anticoagulated patients with permanent atrial fibrillation correlated with elevated von Willebrand factor and interleukin-6. During a 3-year follow-up, ischemic stroke (n = 12, 10.9%) occurred more commonly among atrial fibrillation patients who had circulating TF (p = 0.002) or FXIa (p = 0.013). CONCLUSIONS: These data suggest that circulating active coagulation factors, in particular TF and FXIa, can be detected despite oral anticoagulation in a significant proportion of patients with atrial fibrillation, and could represent novel markers of persistent prothrombotic alterations predisposing to ischemic stroke. PMID- 27695491 TI - Tricuspid annulus plane systolic excursion (TAPSE) has superior predictive value compared to right ventricular to left ventricular ratio in normotensive patients with acute pulmonary embolism. AB - INTRODUCTION: Right ventricular dysfunction (RVD) is an indicator of poor prognosis in normotensive patients with acute pulmonary embolism (APE). The aim of this study was to compare right ventricular (RV)/left ventricular (LV) ratio measured by echocardiography and multidetector computed tomography (MDCT) with tricuspid annulus plane systolic excursion (TAPSE) as a prognostic factor of APE related 30-day mortality. MATERIAL AND METHODS: We examined 76 patients with confirmed APE, hemodynamically stable at admission. We evaluated the prognostic value of RV/LV ratio in the apical 4-chamber view and TAPSE measured at echocardiography and the MDCT RV/LV ratio. RESULTS: Thirty-day APE-related mortality was 10.5% (8 patients). The area under the curve (AUC) for TAPSE in the prediction of APE-related mortality was higher (p < 0.00001) (0.905, 95% CI: 0.828-0.983) than the AUC of the echo RV/LV ratio (0.427, 95% CI: 0.183-0.672) and MDCT RV/LV ratio (0.371, 95% CI: 0.145-0.598). In univariable Cox analysis, TAPSE was the only significant mortality predictor, with hazard ratio (HR) 0.73 (95% CI: 0.62-0.87, p = 0.0004). In multivariable Cox analysis TAPSE was the only significant mortality predictor, with HR 0.62 (95% CI: 0.46-0.85; p = 0.003), while age, heart rate, and RV/LV ratio in echo or MDCT were non-significant. TAPSE <= 15 mm was a significant predictor of APE-related mortality, with HR 26.2 (95% CI: 3.2-214.1; p = 0.002), PPV 44% and NPV 98%. CONCLUSIONS: The TAPSE is preferable to echo and MDCT RV/LV ratio for risk stratification in initially normotensive patients with APE. The TAPSE <= 15 mm identifies patients with an increased risk of 30-day APE-related mortality. PMID- 27695492 TI - Subclinical cardiovascular disease markers and vitamin D deficiency in non dialysis chronic kidney disease patients. AB - INTRODUCTION: Since 25-hydroxyvitamin D (25(OH)D) deficiency has been linked to an increased risk for cardiovascular disease (CVD) in the hemodialysis population, we aimed to determine the relationship between serum 25(OH)D level and markers of subclinical CVD in non-dialysis chronic kidney disease (CKD) patients. MATERIAL AND METHODS: This cross-sectional, single-center study prospectively enrolled 87 clinically stable CKD patients (median age: 61 (57-66) years, 51% male, median estimated glomerular filtration rate (eGFR): 32 (27-37) ml/min). Five markers of subclinical CVD were assessed: intima-media thickness, abdominal aortic calcifications (AAC) using the Kauppila score, cardio-ankle vascular index, ankle-brachial index (ABI) and interventricular septum thickness. RESULTS: Vascular (37%), glomerular (23%) and interstitial (18%) nephropathies were the main causes of CKD. 25(OH)D had a median value of 14 (12.5-17.1) ng/ml, and its levels decreased with eGFR (rs = 0.19; p = 0.04). Patients with 25(OH)D deficiency (54%) were older, had a higher serum alkaline phosphatase level, lower ABI and higher AAC score. There were no differences between the two groups regarding other traditional or non-traditional risk factors for atherosclerosis. The association between subclinical CVD markers and 25(OH)D was further evaluated in multivariable binomial logistic regression models adjusted for CV risk factors. Lower 25(OH)D level was retained as an independent predictor only for pathological ABI. CONCLUSIONS: This is the first study to evaluate the relationship between a large set of subclinical CVD markers and 25(OH)D deficiency in non-dialysis CKD patients. We found that hypovitaminosis D is associated with subclinical peripheral arterial disease, independently of other cardiovascular risk factors. PMID- 27695493 TI - Congenital duodenal obstruction with delayed presentation: seven years of experience. AB - INTRODUCTION: The duodenum is the most common site for congenital intestinal obstruction. The duodenal web with a central hole can present without any overt signs of obstruction at a later age. MATERIAL AND METHODS: Over a 7-year period, children with congenital intestinal obstruction were identified in this study. The complications and operative findings of patients with duodenal web with conditions such as wind sock deformity and delayed diagnosis were evaluated in this study. RESULTS: This study included 81 infants with congenital intestinal obstruction. At operation, 48 patients demonstrated duodenal obstruction with atresia in 27, annular pancreas in 15 and malrotation in 6. Also, we observed incomplete obstruction of the duodenum due to a fenestrated web in 8 patients. The age of these patients at operation time ranged from 5 days to 72 months. Fifty percent of affected patients were associated with trisomy 21, all of whom exhibited failure to thrive due to food intolerance. The patients older than 2 years presented with major complications of gastroesophageal reflux such as esophageal ulcer, stricture and dysphagia. Additionally we had a unique case of a patient who had been referred with an epigastric mass. During the operation, we found 440 seeds of various fruits in the stomach and the first portion of the duodenum. CONCLUSIONS: Our study emphasizes that duodenal web with a central hole can present without signs of obstruction at a later age with only failure to thrive and food intolerance. Therefore a high index of suspicion is necessary for diagnosis when it presents beyond the usual age. PMID- 27695494 TI - Socioeconomic determinants of prostate-specific antigen testing and estimation of the prevalence of undiagnosed prostate cancer in an elderly Polish population based on the PolSenior study. AB - INTRODUCTION: Socioeconomic determinants of prostate-specific antigen (PSA) testing and prevalence of undiagnosed prostate cancer (PCa) in the Polish population are poorly understood. The aim of this study was to identify factors associated with PSA testing in elderly Polish men, and estimate the size of the population at risk of PCa related to PSA non-testing. MATERIAL AND METHODS: We analyzed questionnaire-derived data concerning PSA testing, obtained in 2567 elderly and 332 younger (age: 55-59) participants of the population-based PolSenior study. Additionally, PSA was measured in 2414 subjects. RESULTS: The PSA had previously been tested in 41.2% of elderly and in 24.8% of younger participants. Non-smoking status (OR = 2.06, p < 0.001), higher personal income (OR = 1.56, p < 0.001), better education (OR = 1.49, p = 0.001), previous white collar work (OR = 1.37, p = 0.005), alcohol abstinence (OR = 1.28, p = 0.02), married status (OR = 1.24, p = 0.04), dependence in Instrumental Activities of Daily Living (IADL) but not in Activities of Daily Living (ADL) (OR = 0.65, p < 0.001), and dependence in ADL (OR = 0.55, p < 0.001) were independent predictors of previous PSA testing in elderly participants. There were 31 elderly previously treated for PCa (calculated standardized prevalence: 935 per 100,000 elderly population). The PSA levels > 4 ng/ml were found in 12.8% of 65-74-year-old and 4.5% of 55-59-year-old previously non-tested participants. We calculated the standardized prevalence rate of undiagnosed PCa as approximately 1370 and 2352 cases per 100,000 population aged 55-59 and 65-74 years, respectively. CONCLUSIONS: In Poland, 58.8% of elderly men have never had PSA tested. These were less likely to be functionally independent, married, better educated, non smokers or to have previous office employment or higher than average personal income. Our data suggest substantial underdiagnosis of prostate cancer among Polish men. PMID- 27695495 TI - Dialkylcarbamoyl chloride-impregnated dressing for the prevention of surgical site infection in women undergoing cesarean section: a pilot study. AB - INTRODUCTION: Incisional surgical site infections (SSIs) occur in approximately 1.8-9.2% of patients undergoing cesarean section (CS) and contribute to prolonged hospitalization time and increased treatment costs. Dressings impregnated with dialkylcarbamoyl chloride (DACC) are an innovative approach to wound treatment based on a solely physical mechanism of action, and therefore can be used safely and without time restrictions in women during the puerperal and lactation period. MATERIAL AND METHODS: A single-blinded randomized, controlled pilot study was conducted at the Mazovian Brodno Hospital, a tertiary care hospital, between December 2013 and March 2014, and it evaluated the presence of superficial and deep SSIs in patients during the first 14 days after a CS. Patients were randomly allocated to receive treatment with either a DACC dressing or a standard surgical dressing. RESULTS: One hundred and forty-two patients after planned or emergency CS were enrolled in the study. No significant differences between the groups were observed with regard to patients' basic demographic and perioperative characteristics. The rate of superficial and deep SSIs was 2.8% in the group of patients who received a DACC dressing compared to 9.8% in the group with a standard surgical dressing (p = 0.08). Patients with SSIs who received a standard surgical dressing required systemic antibiotic therapy significantly more frequently (p = 0.03). Based on the logistic regression model developed, the pre pregnancy body mass index was the only statistically significant risk factor for SSI (p = 0.015). CONCLUSIONS: The results of the pilot study indicate a decreasing tendency of the SSI rate in patients after a CS who received DACC impregnated dressings. PMID- 27695497 TI - Evaluation of medical and psychological parameters of quality of life in supraventricular tachyarrhythmia children. A comparison with healthy children. AB - INTRODUCTION: There are only a few available studies evaluating quality of life (QoL) in pediatric patients with cardiac arrhythmia. The aim of the study was to evaluate medical and psychological parameters of the QoL in children with a diagnosed supraventricular tachyarrhythmia (SVT) and to compare the obtained data with a group of healthy children (HC). MATERIAL AND METHODS: Inclusion criteria: children aged 7-18 with SVT, treated at Poznan University of Medical Sciences, Department of Pediatric Cardiology. The evaluation tools were the WHOQOL-BREF instrument and a questionnaire related to the patient's feelings and observations concerning arrhythmia (Pediatric Arrhythmia Related Score - PARS), developed by the authors and adjusted to the group of arrhythmia patients. RESULTS: The study included 180 SVT children and 83 HC. On the basis of WHOQOL-BREF the SVT group was found to have lower assessment values of QoL within the physical domain (Phd) (mean +/- SD: 65.7 +/-15.8 vs. 81.6 +/-12.8; p < 0.0001) and psychological domain (Psd) (mean +/- SD: 75.8 +/-15.2 vs. 81.3 +/-14.1; p < 0.005). No significant differences were found within the social relationships domain or the environment domain. On the basis of PARS in the SVT group the patients reported significantly increased symptoms within Phd (mean +/- SD: 2.3 +/-0.7 vs. 1.6 +/- 0.3; p < 0.0001) as well as increased negative feelings within Psd (mean +/- SD: 2.3 +/ 0.7 vs. 2.1 +/- 0.6; p < 0.005). CONCLUSIONS: Medical and psychological parameters of the QoL in SVT children are significantly lower in comparison with HC. A diagnosis of SVT has no influence on the social and environmental areas of QoL. The PARS appears to be a useful tool to supplement the generic questionnaire for QoL evaluation in SVT children. PMID- 27695496 TI - Prediction of incidence and bio-psycho-socio-cultural risk factors of post-partum depression immediately after birth in an Iranian population. AB - INTRODUCTION: Post-partum depression (PPD) is the most prevalent mental problem associated with childbirth. The purpose of the present study was to determine the incidence of early PPD and possible relevant risk factors among women attending primary health centers in Mazandaran province, Iran for the first time. MATERIAL AND METHODS: A longitudinal cohort study was conducted among 2279 eligible women during weeks 32-42 of pregnancy to determine bio-psycho-socio-cultural risk factors of depression at 2 weeks post-partum using the Iranian version of the Edinburgh Postnatal Depression Scale (EPDS). Univariate and hierarchical multiple logistic regression models were used for data analysis. RESULTS: Among 1,739 mothers whose EPDS scores were <= 12 during weeks 32-42 of gestation and at the follow-up study, the cumulative incidence rate of depression was 6.9% (120/1,739) at 2 weeks post-partum. In the multivariate model the factor that predicted depression symptomatology at 2 weeks post-partum was having psychiatric distress in pregnancy based on the General Health Questionnaire (GHQ) (OR = 1.06, (95% CI: 1.04-1.09), p = 0.001). The risk of PPD also lower in those with sufficient parenting skills (OR = 0.78 (95% CI: 0.69-0.88), p = 0.001), increased marital satisfaction (OR = 0.94 (95% CI: 0.9-0.99), p = 0.03), increased frequency of practicing rituals (OR = 0.94 (95% CI: 0.89-0.99), p = 0.004) and in those whose husbands had better education (OR = 0.03 (95% CI: 0.88-0.99), p = 0.04). CONCLUSIONS: The findings indicated that a combination of demographic, sociological, psychological and cultural risk factors can make mothers vulnerable to PPD. PMID- 27695498 TI - Magnetic resonance imaging of neonates in the magnetic resonance compatible incubator. AB - INTRODUCTION: The authors present the first experience in neonatal magnetic resonance imaging (MRI) examinations using an MR compatible incubator (INC) at the Institute of Mother and Child. MATERIAL AND METHODS: Forty-nine examinations of 47 newborns (20 girls, 27 boys) were performed using the GE Signa HDxt 1.5T system and INC Nomag IC 1.5. Demographic data, anesthetic methods and MRI findings in the INC in comparison with previously performed imaging were analyzed. RESULTS: Thirty-two neonates were prematurely born (68.1%) at gestational age 23-37 weeks, mean: 29.9 weeks. They were examined at 26 weeks postmenstrual age to 1 month corrected age, mean: 37.5 weeks. Body weight of newborns on the study day was 600-4300 g, mean: 2724 g. Seventeen (34.7%) children were examined in physiological sleep, 32 (65.3%) anesthetized. In none of them did anesthesiological complications or disease worsening occur. In 43 (91.5%) children brain MRI was performed, in 4 (8.5%) MRI of the spinal cord and canal and of the abdomen/pelvis. In children prenatally examined by MRI, the INC provided new diagnostic information in 5 (83.3%) cases, in neonates studied after birth by ultrasound in 32 (82%). Magnetic resonance imaging in the INC did not entail additional knowledge in 9 (18.7%) cases. CONCLUSIONS: The INC enables MRI in preterm newborns and those with low/extremely low body weight. These studies are necessary to assess the extent of changes in the central nervous system and other organs. Incubator coils, designed specifically for neonates, allow more accurate diagnosis than previously used coils for adults. MRI results allow one to determine prognosis, for more accurate planning of diagnostics, helping to make appropriate therapeutic decisions. PMID- 27695499 TI - Comparative investigation of antioxidant activity of human serum blood by amperometric, voltammetric and chemiluminescent methods. AB - INTRODUCTION: A blood test can provide important information about the functional state of the antioxidant system. Malfunction of this system increases the concentration of free radicals and can cause oxidative stress. A difficulty in assessing oxidative stress is the lack of a universal method for determining the antioxidant activity (AOA) of blood components, because of their different nature. MATERIAL AND METHODS: The objects of investigation were sera of 30 male patients with a diagnosis of alcohol dependence syndrome and healthy donors. Comparative investigation of total antioxidant activity (TAA) of human serum blood was carried out by voltammetric (VA), amperometric (AM) and chemiluminescent (HL) methods. RESULTS: All applied methods revealed that serum TAA of the patients with alcoholism is lower than TAA of healthy donors (control group); according to amperometric method the average value of serum TAA was 850 +/-210 nA * s, and 660 +/-150 nA * s for healthy donors and alcoholics respectively (p < 0.05). Similar trend was revealed by chemiluminescence and voltammetry methods. The results confirm that thiol compounds make a significant contribution to the antioxidant activity of serum. The average thiol concentrations were 0.94 +/-0.34 mmol/l and 1.21 +/-0.36 mmol/l (p < 0.05) for alcoholics and healthy donors respectively. Decreasing thiol concentration in blood of alcoholics leads to depletion of antioxidant systems of blood. However, the differences between the results of AM, VA and HL methods were significant, because they reflected different aspects of antioxidant activity. CONCLUSIONS: For objective assessment of antioxidant activity of biological objects, we suggest using methods based on different model systems. PMID- 27695500 TI - Obstructive sleep apnea predicts risk of metabolic syndrome independently of obesity: a meta-analysis. AB - INTRODUCTION: Obstructive sleep apnea (OSA) has been suggested to be associated with a high risk of metabolic syndrome (MS). However, results on whether the association between OSA and risk of MS is independent of obesity, and the effect of nocturnal intermittent hypoxia (IH) on MS, are conflicting. Our purpose was to estimate the magnitude of the independent association between OSA and risk of MS and further explore whether nocturnal IH in OSA plays a role in MS risk. MATERIAL AND METHODS: The PubMed and EMBASE databases were systematically searched (until January 21, 2015) for available observational evidence. Unadjusted and body mass index (BMI)-adjusted pooled odds ratios (ORs) for MS in OSA or higher nocturnal IH were calculated using fixed or random models. Tests of homogeneity, publication bias, and robustness of the results were performed. RESULTS: A total of 13 independent studies (involving 857 participants in 3 case-control studies and 7077 participants in 10 cross-sectional studies) were included. The OSA was significantly associated with an increased risk of MS in a meta-analysis of 10 studies (pooled OR = 1.72, 95% CI: 1.31-2.26, p < 0.001), with a BMI-adjusted pooled OR of 1.97 (95% CI: 1.34-2.88, p < 0.001). Pooled results from 3 studies on the oxygen desaturation index (ODI) and MS risk (OR = 1.96, 95% CI: 1.73-2.22, p < 0.001) and 3 studies on the cumulative percentage of sleep time with SpO2 below 90% (CT90) and MS risk (OR = 1.05, 95% CI: 1.02-1.07, p < 0.001) were also significant. CONCLUSIONS: Our findings demonstrated a significant association between OSA and increased MS risk independent of BMI, and further indicated a role of nocturnal IH in this association. PMID- 27695501 TI - Effectiveness and safety of vedolizumab for treatment of Crohn's disease: a systematic review and meta-analysis. AB - INTRODUCTION: The aim of this systematic review (SR) and meta-analysis was to assess the efficacy and safety of vedolizumab in the treatment of Crohn's disease (CD). MATERIAL AND METHODS: A systematic literature search was conducted in Medline/PubMed, Embase and Cochrane Library until 25 January, 2015. Included studies were critically appraised according to the PRISMA protocol. Assessment in specified subgroups of CD patients and meta-analysis with Revman software were performed. RESULTS: Two randomized controlled trial (RCTs) were included in a meta-analysis for the induction phase of therapy: GEMINI II and GEMINI III. The clinical response was significantly higher for patients who received vedolizumab compared to placebo in the general population (risk benefit (RB) = 1.48; p = 0.0006) and in both analyzed subgroups: patients with previous failure of anti TNFs treatment (RB = 1.51; p = 0.006) and patients naive to earlier anti-TNFs (RB = 1.41; p = 0.001). The clinical remission in the general population and subpopulation of TNF-antagonist naive patients was significantly higher for patients who received vedolizumab compared to placebo (RB = 1.77; p = 0.003; RB = 2.29; p = 0.0004; respectively). Meta-analysis for adverse events, serious adverse events (SAEs) and serious infections, revealed that vedolizumab was as safe as placebo in the induction phase of therapy. CONCLUSIONS: The clinical response was significantly higher for patients who received vedolizumab in the general population and in both analyzed subgroups of patients. The clinical remission in the general population and subpopulation of TNF-antagonist naive patients was significantly higher for vedolizumab, but no significant differences were revealed in the subgroup of patients with previous TNF antagonist failure. PMID- 27695502 TI - An indirect comparison of infliximab versus adalimumab or golimumab for active ulcerative colitis. AB - INTRODUCTION: The aim of the study was to compare adalimumab or golimumab with infliximab in patients with moderately-to-severely active ulcerative colitis (UC). MATERIAL AND METHODS: This paper was prepared according to the PRISMA guidelines. The systematic literature search was performed in PubMed, Embase, and Cochrane Library. No direct head-to-head comparisons for infliximab vs. adalimumab or golimumab were available so an indirect comparison according to the Bucher method was performed after a homogeneity evaluation of the included studies. RESULTS: Six RCTs were included in the systematic review. An indirect comparison was performed, which revealed that infliximab was more effective in inducing clinical response compared with both doses of adalimumab (160/80 mg or 80/40 mg; p < 0.05), and, in clinical remission, infliximab was more effective than adalimumab (only for a dosage regime of 80/40 mg; p < 0.05). No statistically significant differences in clinical response and clinical remission were observed between infliximab and golimumab in the induction phase. A significant (p < 0.05) advantage only of infliximab compared with adalimumab at doses of 80/40 mg and 80/160 mg was seen in terms of clinical response in the maintenance phase (up to 52-54 weeks). The indirect comparison revealed that serious adverse events were significantly more frequent among patients treated with a maintenance dose of 100 mg of golimumab compared with those treated with infliximab (p < 0.05). CONCLUSIONS: No significant differences in efficacy in the maintenance phase between infliximab and golimumab or adalimumab were revealed. Infliximab proved to be more effective than adalimumab but of similar efficacy to that of golimumab in the induction phase. PMID- 27695503 TI - Prognostic significance of cyclooxygenase-2 expression in patients with hepatocellular carcinoma: a meta-analysis. AB - INTRODUCTION: Cyclooxygenase-2 (COX-2) is believed to be an important enzyme in the carcinogenesis of hepatocellular carcinoma (HCC). However, it is still controversial whether COX-2 expression can be regarded as a prognostic factor for HCC patients. We performed a systematic review and meta-analysis of studies assessing the clinical and prognostic significance of COX-2 expression in HCC. MATERIAL AND METHODS: Identification and review of publications assessing clinical or prognostic significance of COX-2 expression in HCC until November 1, 2014. A meta-analysis was performed to clarify the association between COX-2 expression and clinical outcomes. RESULTS: A total of 11 publications met the criteria and included 943 cases. Analysis of these data showed that COX-2 expression was not significantly correlated with capsular formation (OR = 0.84, 95% confidence interval (CI): 0.46-1.55, p = 0.58), tumor TNM stage (OR = 0.73, 95% CI: 0.23-2.33, p = 0.59), vascular invasion (OR = 1.04, 95% CI: 0.25-4.35, p = 0.96), tumor size (OR = 0.78, 95% CI: 0.21-2.86, p = 0.71), or tumor differentiation degree (OR = 1.08, 95% CI: 0.42-2.79, p = 0.87). However, in the identified studies, COX-2 expression was strongly associated with high alpha fetoprotein level (OR = 1.83, 95% CI: 1.01-3.33, p = 0.05), HBsAg status (OR = 1.85, 95% CI: 1.13-3.03, p = 0.01), decreased overall survival (relative risk (RR): 1.54, 95% CI: 1.18-2.02, p = 0.001) and decreased disease-free survival (RR = 1.49, 95% CI: 1.22-1.81, p < 0.001). CONCLUSIONS: This meta-analysis shows that COX-2 expression in HCC is associated with decreased overall and disease-free survival and thus marks a worse prognosis. Nevertheless, more large sample and well-designed studies are warranted to confirm this finding. PMID- 27695504 TI - Vitamin D receptor gene FokI polymorphisms and tuberculosis susceptibility: a meta-analysis. AB - INTRODUCTION: The association between FokI polymorphism of vitamin D receptor (VDR) and tuberculosis (TB) susceptibility has been investigated previously; however, the results were inconsistent and conflicting. In the present study, a meta-analysis was performed to assess the relationship between VDR FokI gene polymorphism and the risk of TB. MATERIAL AND METHODS: Databases including PubMed and Embase were searched for genetic association studies of FokI polymorphism of vitamin D receptor (VDR) and TB. Data were extracted by two independent authors and the pooled odds ratio (OR) with 95% confidence interval (CI) was calculated to assess the strength of the association between VDR FokI gene polymorphism and TB risk. Meta-regression and subgroup analyses were performed to identify the source of heterogeneity. RESULTS: Thirty-four studies with a total of 5669 cases and 6525 controls were reviewed in the present meta-analysis. A statistically significant correlation was found between VDR FokI gene polymorphism and increased TB risk in two comparison models: the homozygote model (ff vs. FF: OR = 1.37, 95% CI: 1.17-1.60; Pheterogeneity = 0.001) and the recessive model (ff vs. Ff + FF: OR = 1.32, 95% CI: 1.14-1.52; Pheterogeneity = 0.006). Meta-regression found no source contributing to heterogeneity. However, sub-group analyses revealed that there was a statistically increased TB risk in the East and Southeast Asian population. CONCLUSIONS: Synthesis of the available studies suggests that homozygosity for the FokI polymorphism of the VDR gene might be associated with an increased TB risk, especially in the East and Southeast Asian population. Additional well-designed, larger-scale epidemiological studies among different ethnicities are needed. PMID- 27695505 TI - History and current use of mild therapeutic hypothermia after cardiac arrest. AB - In spite of many years of development and implementation of pre-hospital advanced life support programmes, the survival rate of out-of-hospital cardiac arrest (OHCA) used to be very poor. Neurologic injury from cerebral hypoxia is the most common cause of death in patients with OHCA. In the past two decades, post resuscitation care has developed many new concepts aimed at improving the neurological outcome and survival rate of patients after cardiac arrest. Systematic post-cardiac arrest care after the return of spontaneous circulation, including induced mild therapeutic hypothermia (TH) in selected patients, is aimed at significantly improving rates of long-term neurologically intact survival. This review summarises the history and current knowledge in the field of mild TH after OHCA. PMID- 27695508 TI - Reversal agents of non-vitamin K dependent anticoagulants: a rapid review of the changing horizon. AB - The newer non-vitamin K dependent anticoagulants (NOACs) have provided a new tool in the armamentarium of physicians treating nonvalvular atrial fibrillation and thromboembolism. Slowly, but steadily, there has been an increased preference of NOACs over vitamin K antagonists. However, the major limiting factor and the concern that precluded their use was lack of reversal in emergent situations. With the advent of reversal agents such as idarucizumab, andexanet alfa and PER977, this gap is also being filled. This will further increase the spectrum of usage of NOACs. In this review we present the detailed information on the completed trials on the reversal agents, the ongoinng trials, and their site of action. The reversal agent idarucizumab is FDA approved and readily available. The others are in clinical trials and are soon expected to be available in clinical practice.

PMID- 27695506 TI - Diabetic macular edema, retinopathy and age-related macular degeneration as inflammatory conditions. AB - Diabetic macular edema (DME) and diabetic retinopathy (DR) are complications affecting about 25% of all patients with long-standing type 1 and type 2 diabetes mellitus and are a major cause of significant decrease in vision and quality of life. Age-related macular degeneration (AMD) is not uncommon, and diabetes mellitus affects the incidence and progression of AMD through altering hemodynamics, increasing oxidative stress, accumulating advanced glycation end products, etc. Recent studies suggest that DME, DR and AMD are inflammatory conditions characterized by a breakdown of the blood-retinal barrier, inflammatory processes and an increase in vascular permeability. Key factors that seem to have a dominant role in DME, DR and AMD are angiotensin II, prostaglandins and the vascular endothelial growth factor and a deficiency of anti-inflammatory bioactive lipids. The imbalance between pro- and anti inflammatory eicosanoids and enhanced production of pro-angiogenic factors may initiate the onset and progression of DME, DR and AMD. This implies that bioactive lipids that possess anti-inflammatory actions and suppress the production of angiogenic factors could be employed in the prevention and management of DME, DR and AMD.

AB - Inequities in access to HIV prevention and treatment for children remain a global challenge and a black spot to effective HIV prevention and response especially in many HIV endemic countries like Uganda. In Uganda while about 51% of the adults living with HIV are on antiretrovirals, only 39% of the children aged 0-14 years accessed the needed HIV care in 2014. In this article, it is argued that much focus on health system interventions with little regard to bridging the gap between health facilities, where much of the care is provided, and the communities, where children are conceived, born and cared for, contributes to and sustains this inequality. Investments need to be made in building and implementing models that create and enhance linkages between communities and health care facilities. Success factors from the Towards an AIDS Free Generation in Uganda project model in creating these linkages are bringing all actors together in one approach, building on existing community structures and enabling community health workers to be the linking pin between communities and facilities. Only with models like this, full elimination of mother-to-child transmission and paediatric HIV care coverage (0-14 years) can be reached in Uganda and other HIV endemic countries. PMID- 27695511 TI - A grounded theory of positive youth development through sport based on results from a qualitative meta-study. AB - The overall purpose of this study was to create a model of positive youth development (PYD) through sport grounded in the extant qualitative literature. More specifically, the first objective was to review and evaluate qualitative studies of PYD in sport. The second objective was to analyze and synthesize findings from these studies. Following record identification and screening, 63 articles were retained for analysis. Meta-method analysis revealed strengths of studies were the use of multiple data collection and validity techniques, which produced high-quality data. Weaknesses were limited use of 'named' methodologies and inadequate reporting of sampling procedures. Philosophical perspectives were rarely reported, and theory was used sparingly. Results of an inductive meta-data analysis produced three categories: PYD climate (adult relationships, peer relationships, and parental involvement), life skills program focus (life skill building activities and transfer activities), and PYD outcomes (in personal, social, and physical domains). A model that distinguishes between implicit and explicit processes to PYD is presented. PMID- 27695507 TI - Novel surgical techniques, regenerative medicine, tissue engineering and innovative immunosuppression in kidney transplantation. AB - On the 60th anniversary of the first successfully performed renal transplantation, we summarize the historical, current and potential future status of kidney transplantation. We discuss three different aspects with a potential significant influence on kidney transplantation progress: the development of surgical techniques, the influence of regenerative medicine and tissue engineering, and changes in immunosuppression. We evaluate the standard open surgical procedures with modern techniques and compare them to less invasive videoscopic as well as robotic techniques. The role of tissue engineering and regenerative medicine as a potential method for future kidney regeneration or replacement and the interesting search for novel solutions in the field of immunosuppression will be discussed. After 60 years since the first successfully performed kidney transplantation, we can conclude that the greatest achievements are associated with the development of surgical techniques and with planned systemic immunosuppression. PMID- 27695512 TI - Detecting Spatio-Temporal Modes in Multivariate Data by Entropy Field Decomposition. AB - A new data analysis method that addresses a general problem of detecting spatio temporal variations in multivariate data is presented. The method utilizes two recent and complimentary general approaches to data analysis, information field theory (IFT) and entropy spectrum pathways (ESP). Both methods reformulate and incorporate Bayesian theory, thus use prior information to uncover underlying structure of the unknown signal. Unification of ESP and IFT creates an approach that is non-Gaussian and non-linear by construction and is found to produce unique spatio-temporal modes of signal behavior that can be ranked according to their significance, from which space-time trajectories of parameter variations can be constructed and quantified. Two brief examples of real world applications of the theory to the analysis of data bearing completely different, unrelated nature, lacking any underlying similarity, are also presented. The first example provides an analysis of resting state functional magnetic resonance imaging (rsFMRI) data that allowed us to create an efficient and accurate computational method for assessing and categorizing brain activity. The second example demonstrates the potential of the method in the application to the analysis of a strong atmospheric storm circulation system during the complicated stage of tornado development and formation using data recorded by a mobile Doppler radar. Reference implementation of the method will be made available as a part of the QUEST toolkit that is currently under development at the Center for Scientific Computation in Imaging. PMID- 27695513 TI - Will life find a way? Evolution of marine species under global change. AB - Projections of marine biodiversity and implementation of effective actions for its maintenance in the face of current rapid global environmental change are constrained by our limited understanding of species' adaptive responses, including transgenerational plasticity, epigenetics and natural selection. This special issue presents 13 novel studies, which employ experimental and modelling approaches to (i) investigate plastic and evolutionary responses of marine species to major global change drivers; (ii) ask relevant broad eco-evolutionary questions, implementing multiple species and populations studies; (iii) show the advantages of using advanced experimental designs and tools; (iv) construct novel model organisms for marine evolution; (v) help identifying future challenges for the field; and (vi) highlight the importance of incorporating existing evolutionary theory into management solutions for the marine realm. What emerges is that at least some populations of marine species have the ability to adapt to future global change conditions. However, marine organisms' capacity for adaptation appears finite, due to evolutionary trade-offs and possible rapid losses in genetic diversity. This further corroborates the idea that acquiring an evolutionary perspective on how marine life will respond to the selective pressure of future global changes will guide us in better identifying which conservation efforts will be most needed and most effective. PMID- 27695514 TI - Physiological plasticity and local adaptation to elevated pCO2 in calcareous algae: an ontogenetic and geographic approach. AB - To project how ocean acidification will impact biological communities in the future, it is critical to understand the potential for local adaptation and the physiological plasticity of marine organisms throughout their entire life cycle, as some stages may be more vulnerable than others. Coralline algae are ecosystem engineers that play significant functional roles in oceans worldwide and are considered vulnerable to ocean acidification. Using different stages of coralline algae, we tested the hypothesis that populations living in environments with higher environmental variability and exposed to higher levels of pCO 2 would be less affected by high pCO 2 than populations from a more stable environment experiencing lower levels of pCO 2. Our results show that spores are less sensitive to elevated pCO 2 than adults. Spore growth and mortality were not affected by pCO 2 level; however, elevated pCO 2 negatively impacted the physiology and growth rates of adults, with stronger effects in populations that experienced both lower levels of pCO 2 and lower variability in carbonate chemistry, suggesting local adaptation. Differences in physiological plasticity and the potential for adaptation could have important implications for the ecological and evolutionary responses of coralline algae to future environmental changes. PMID- 27695515 TI - An in situ assessment of local adaptation in a calcifying polychaete from a shallow CO2 vent system. AB - Ocean acidification (OA) is likely to exert selective pressure on natural populations. Our ability to predict which marine species will adapt to OA and what underlies this adaptive potential is of high conservation and resource management priority. Using a naturally low-pH vent site in the Mediterranean Sea (Castello Aragonese, Ischia) mirroring projected future OA conditions, we carried out a reciprocal transplant experiment to investigate the relative importance of phenotypic plasticity and local adaptation in two populations of the sessile, calcifying polychaete Simplaria sp. (Annelida, Serpulidae, Spirorbinae): one residing in low pH and the other from a nearby ambient (i.e. high) pH site. We measured a suite of fitness-related traits (i.e. survival, reproductive output, maturation, population growth) and tube growth rates in laboratory-bred F2 generation individuals from both populations reciprocally transplanted back into both ambient and low-pH in situ habitats. Both populations showed lower expression in all traits, but increased tube growth rates, when exposed to low-pH compared with high-pH conditions, regardless of their site of origin suggesting that local adaptation to low-pH conditions has not occurred. We also found comparable levels of plasticity in the two populations investigated, suggesting no influence of long-term exposure to low pH on the ability of populations to adjust their phenotype. Despite high variation in trait values among sites and the relatively extreme conditions at the low pH site (pH < 7.36), response trends were consistent across traits. Hence, our data suggest that, for Simplaria and possibly other calcifiers, neither local adaptations nor sufficient phenotypic plasticity levels appear to suffice in order to compensate for the negative impacts of OA on long-term survival. Our work also emphasizes the utility of field experiments in natural environments subjected to high level of pCO 2 for elucidating the potential for adaptation to future scenarios of OA. PMID- 27695516 TI - Transgenerational plasticity of reproduction depends on rate of warming across generations. AB - Predicting the impacts of climate change to biological systems requires an understanding of the ability for species to acclimate to the projected environmental change through phenotypic plasticity. Determining the effects of higher temperatures on individual performance is made more complex by the potential for environmental conditions experienced in previous and current generations to independently affect phenotypic responses to high temperatures. We used a model coral reef fish (Acanthochromis polyacanthus) to investigate the influence of thermal conditions experienced by two generations on reproductive output and the quality of offspring produced by adults. We found that more gradual warming over two generations, +1.5 degrees C in the first generation and then +3.0 degrees C in the second generation, resulted in greater plasticity of reproductive attributes, compared to fish that experienced the same increase in one generation. Reproduction ceased at the projected future summer temperature (31.5 degrees C) when fish experienced +3.0 degrees C for two generations. Additionally, we found that transgenerational plasticity to +1.5 degrees C induced full restoration of thermally affected reproductive and offspring attributes, which was not possible with developmental plasticity alone. Our results suggest that transgenerational effects differ depending on the absolute thermal change and in which life stage the thermal change is experienced. PMID- 27695517 TI - Multi-generational responses of a marine polychaete to a rapid change in seawater pCO2. AB - Little is known of the capacity that marine metazoans have to evolve under rapid p CO 2 changes. Consequently, we reared a marine polychaete, Ophryotrocha labronica, previously cultured for approximately 33 generations under a low/variable pH regime, under elevated and low p CO 2 for six generations. The strain used was found to be tolerant to elevated p CO 2 conditions. In generations F1 and F2 females' fecundity was significantly lower in the low p CO 2 treatment. However, from generation F3 onwards there were no differences between p CO 2 treatments, indicating that trans-generational effects enabled the restoration and maintenance of reproductive output. Whilst the initial fitness recovery was likely driven by trans-generational plasticity (TGP), the results from reciprocal transplant assays, performed using F7 individuals, made it difficult to disentangle between whether TGP had persisted across multiple generations, or if evolutionary adaptation had occurred. Nonetheless, both are important mechanisms for persistence under climate change. Overall, our study highlights the importance of multi-generational experiments in more accurately determining marine metazoans' responses to changes in p CO 2, and strengthens the case for exploring their use in conservation, by creating specific p CO 2 tolerant strains of keystone ecosystem species. PMID- 27695518 TI - Transgenerational effects persist down the maternal line in marine sticklebacks: gene expression matches physiology in a warming ocean. AB - Transgenerational effects can buffer populations against environmental change, yet little is known about underlying mechanisms, their persistence or the influence of environmental cue timing. We investigated mitochondrial respiratory capacity (MRC) and gene expression of marine sticklebacks that experienced acute or developmental acclimation to simulated ocean warming (21 degrees C) across three generations. Previous work showed that acute acclimation of grandmothers to 21 degrees C led to lower (optimized) offspring MRCs. Here, developmental acclimation of mothers to 21 degrees C led to higher, but more efficient offspring MRCs. Offspring with a 21 degrees C * 17 degrees C grandmother-mother environment mismatch showed metabolic compensation: their MRCs were as low as offspring with a 17 degrees C thermal history across generations. Transcriptional analyses showed primarily maternal but also grandmaternal environment effects: genes involved in metabolism and mitochondrial protein biosynthesis were differentially expressed when mothers developed at 21 degrees C, whereas 21 degrees C grandmothers influenced genes involved in hemostasis and apoptosis. Genes involved in mitochondrial respiration all showed higher expression when mothers developed at 21 degrees and lower expression in the 21 degrees C * 17 degrees C group, matching the phenotypic pattern for MRCs. Our study links transcriptomics to physiology under climate change, and demonstrates that mechanisms underlying transgenerational effects persist across multiple generations with specific outcomes depending on acclimation type and environmental mismatch between generations. PMID- 27695520 TI - Loss of genetic diversity as a consequence of selection in response to high pCO2. AB - Standing genetic variation may allow for rapid evolutionary response to the geologically unprecedented changes in global conditions. However, there is little known about the consequences of such rapid evolutionary change. Here, we measure genetic responses to experimental low and high pCO 2 levels in purple sea urchin larvae, Strongylocentrotus purpuratus. We found greater loss of nucleotide diversity in high pCO 2 levels (18.61%; 900 MUatm) compared to low pCO 2 levels (10.12%; 400 MUatm). In the wild, this loss could limit the evolutionary capacity of future generations. In contrast, we found minimal evidence that purple sea urchin larvae physiologically respond to high pCO 2 through alternative splicing of transcripts (11 genes), despite a strong signal of alternative splicing between different developmental stages (1193 genes). However, in response to high pCO 2, four of the 11 alternatively spliced transcripts encoded ribosomal proteins, suggesting the regulation of translation as a potential response mechanism. The results of this study indicate that while the purple urchin presently may have enough standing genetic variation in response to rapid environmental change, this reservoir of resilience is a finite resource and could quickly diminish. PMID- 27695519 TI - Selection on oxidative phosphorylation and ribosomal structure as a multigenerational response to ocean acidification in the common copepod Pseudocalanus acuspes. AB - Ocean acidification is expected to have dramatic impacts on oceanic ecosystems, yet surprisingly few studies currently examine long-term adaptive and plastic responses of marine invertebrates to pCO 2 stress. Here, we exposed populations of the common copepod Pseudocalanus acuspes to three pCO 2 regimes (400, 900, and 1550 MUatm) for two generations, after which we conducted a reciprocal transplant experiment. A de novo transcriptome was assembled, annotated, and gene expression data revealed that genes involved in RNA transcription were strongly down regulated in populations with long-term exposure to a high pCO 2 environment, even after transplantation back to control levels. In addition, 747 000 SNPs were identified, out of which 1513 showed consistent changes in nucleotide frequency between replicates of control and high pCO 2 populations. Functions involving RNA transcription and ribosomal function, as well as ion transport and oxidative phosphorylation, were highly overrepresented. We thus conclude that pCO 2 stress appears to impose selection in copepods on RNA synthesis and translation, possibly modulated by helicase expression. Using a physiological hypothesis testing strategy to mine gene expression data, we herein increase the power to detect cellular targets of ocean acidification. This novel approach seems promising for future studies of effects of environmental changes in ecologically important nonmodel organisms. PMID- 27695521 TI - Can trans-generational experiments be used to enhance species resilience to ocean warming and acidification? AB - Human-assisted, trans-generational exposure to ocean warming and acidification has been proposed as a conservation and/or restoration tool to produce resilient offspring. To improve our understanding of the need for and the efficacy of this approach, we characterized life-history and physiological responses in offspring of the marine polychaete Ophryotrocha labronica exposed to predicted ocean warming (OW: + 3 degrees C), ocean acidification (OA: pH -0.5) and their combination (OWA: + 3 degrees C, pH -0.5), following the exposure of their parents to either control conditions (within-generational exposure) or the same conditions (trans-generational exposure). Trans-generational exposure to OW fully alleviated the negative effects of within-generational exposure to OW on fecundity and egg volume and was accompanied by increased metabolic activity. While within-generational exposure to OA reduced juvenile growth rates and egg volume, trans-generational exposure alleviated the former but could not restore the latter. Surprisingly, exposure to OWA had no negative impacts within- or trans-generationally. Our results highlight the potential for trans-generational laboratory experiments in producing offspring that are resilient to OW and OA. However, trans-generational exposure does not always appear to improve traits and therefore may not be a universally useful tool for all species in the face of global change. PMID- 27695522 TI - Adaptation to climate change: trade-offs among responses to multiple stressors in an intertidal crustacean. AB - Trade-offs may influence both physiological and evolutionary responses to co occurring stressors, but their effects on both plastic and adaptive responses to climate change are poorly understood. To test for genetic and physiological trade offs incurred in tolerating multiple stressors, we hybridized two populations of the intertidal copepod Tigriopus californicus that were divergent for both heat and salinity tolerance. Starting in the F2 generation, we selected for increased tolerance of heat, low salinity, and high salinity in replicate lines. After five generations of selection, heat-selected lines had greater heat tolerance but lower fecundity, indicating an energetic cost to tolerance. Lines selected for increased salinity tolerance did not show evidence of adaptation to their respective environments; however, hypo-osmotic selection lines showed substantial loss of tolerance to hyperosmotic stress. Neither of the salinity selection regimes resulted in diminished heat tolerance at ambient salinity; however, simultaneous exposure to heat and hypo-osmotic stress led to decreased heat tolerance, implying a physiological trade-off in tolerance to the two stressors. When we quantified the transcriptomic response to heat and salinity stress via RNA sequencing, we observed little overlap in the stress responses, suggesting the observed synergistic effects of heat and salinity stress were driven by competing energetic demands, rather than shared stress response pathways. PMID- 27695523 TI - Swift thermal reaction norm evolution in a key marine phytoplankton species. AB - Temperature has a profound effect on the species composition and physiology of marine phytoplankton, a polyphyletic group of microbes responsible for half of global primary production. Here, we ask whether and how thermal reaction norms in a key calcifying species, the coccolithophore Emiliania huxleyi, change as a result of 2.5 years of experimental evolution to a temperature ~2 degrees C below its upper thermal limit. Replicate experimental populations derived from a single genotype isolated from Norwegian coastal waters were grown at two temperatures for 2.5 years before assessing thermal responses at 6 temperatures ranging from 15 to 26 degrees C, with pCO 2 (400/1100/2200 MUatm) as a fully factorial additional factor. The two selection temperatures (15 degrees /26.3 degrees C) led to a marked divergence of thermal reaction norms. Optimal growth temperatures were 0.7 degrees C higher in experimental populations selected at 26.3 degrees C than those selected at 15.0 degrees C. An additional negative effect of high pCO 2 on maximal growth rate (8% decrease relative to lowest level) was observed. Finally, the maximum persistence temperature (Tmax) differed by 1-3 degrees C between experimental treatments, as a result of an interaction between pCO 2 and the temperature selection. Taken together, we demonstrate that several attributes of thermal reaction norms in phytoplankton may change faster than the predicted progression of ocean warming. PMID- 27695524 TI - Ocean acidification influences host DNA methylation and phenotypic plasticity in environmentally susceptible corals. AB - As climate change challenges organismal fitness by creating a phenotype environment mismatch, phenotypic plasticity generated by epigenetic mechanisms (e.g., DNA methylation) can provide a temporal buffer for genetic adaptation. Epigenetic mechanisms may be crucial for sessile benthic marine organisms, such as reef-building corals, where ocean acidification (OA) and warming reflect in strong negative responses. We tested the potential for scleractinian corals to exhibit phenotypic plasticity associated with a change in DNA methylation in response to OA. Clonal coral fragments of the environmentally sensitive Pocillopora damicornis and more environmentally robust Montipora capitata were exposed to fluctuating ambient pH (7.9-7.65) and low pH (7.6-7.35) conditions in common garden tanks for ~6 weeks. M. capitata responded weakly, or acclimated more quickly, to OA, with no difference in calcification, minimal separation of metabolomic profiles, and no change in DNA methylation between treatments. Conversely, P. damicornis exhibited diminished calcification at low pH, stronger separation in metabolomic profiles, and responsiveness of DNA methylation to treatment. Our data suggest corals differ in their temporal dynamics and sensitivity for environmentally triggered real-time epigenetic reprogramming. The generation of potentially heritable plasticity via environmental induction of DNA methylation provides an avenue for assisted evolution applications in corals under rapid climate change. PMID- 27695525 TI - Growth rate evolution in improved environments under Prodigal Son dynamics. AB - I use an individual-based model to investigate the evolution of cell division rates in asexual populations under chronic environmental enrichment. I show that maintaining increased growth rates over hundreds of generations following environmental improvement can be limited by increases in cellular damage associated with more rapid reproduction. In the absence of further evolution to either increase damage tolerance or decrease the cost of repair or rate of damage, environmental improvement does not reliably lead to long-term increases in reproductive rate in microbes. Here, more rapid cell division rates also increases damage, leading to selection for damage avoidance or repair, and a subsequent decrease in population growth, which I call Prodigal Son dynamics, because the consequences of 'living fast' force a return to ancestral growth rates. Understanding the conditions under which environmental enrichment is expected to sustainably increase cell division rates is important in applications that require rapid cell division (e.g. biofuel reactors) or seek to avoid the emergence of rapid cell division rates (controlling biofouling). PMID- 27695526 TI - Global change, life-history complexity and the potential for evolutionary rescue. AB - Most organisms have complex life cycles, and in marine taxa, larval life-history stages tend to be more sensitive to environmental stress than adult (reproductive) life-history stages. While there are several models of stage specific adaptation across the life history, the extent to which differential sensitivity to environmental stress (defined here as reductions in absolute fitness across the life history) affects the tempo of adaptive evolution to change remains unclear. We used a heuristic model to explore how commonly observed features associated with marine complex life histories alter a population's capacity to cope with environmental change. We found that increasing the complexity of the life history generally reduces the evolutionary potential of taxa to cope with environmental change. Our model also predicted that genetic correlations in stress tolerance between stages, levels of genetic variance in each stage, and the relative plasticity of different stages, all interact to affect the maximum rate of environmental change that will permit species persistence. Our results suggest that marine organisms with complex life cycles are particularly vulnerable to anthropogenic global change, but we lack empirical estimates of key parameters for most species.

PMID- 27695528 TI - Management of equivocal (early) Fournier's gangrene. AB - BACKGROUND: Fournier's gangrene (FG) is an acute progressive necrotizing fasciitis of the genital area and perineum with possible extension to the abdominal wall. Surgical debridement is the gold standard management modality of established patients. Equivocal (early) FG represents a challenge in diagnosis. The objective of this study was to compare conservative management and early exploration in cases of equivocal (early) FG. METHODS: This was an observational study where data of all patients diagnosed as early FG in our departments over 4 years (2011-2015) were enrolled. Patients were divided into two groups: group 1 with conservative treatment, and group 2 managed with urgent exploration with longitudinal hemiscrotal incision starting from external inguinal ring. All patients' demographics, vital signs, laboratory finding and clinical findings were reported. RESULTS: A total of 28 patients were enrolled in the study. Group 1 was managed with conservative treatment (17 patients) and group 2 underwent urgent exploration (11 patients). Overall, four patients (23.5%) out of 17 patients of group 1 showed a good response to conservative management without any surgical debridement. A total of 13 patients (76.5%) developed gangrenous discoloration and needed surgical debridement later. In group 2, four patients (36.4%) underwent scrotal exploration and release incision only without debridement and showed an excellent clinical outcome. A total of four patients (36.4%) underwent debridement with excision of doubtful deep subcutaneous and fascial tissues. The remaining three patients (27.2%) underwent debridement of necrotic fascia. The hospital stay was significantly shorter in group 2 patients than group 1 (7.5 +/- 3.75 versus 13.4 +/- 5.19 days p < 0.05). The mean number of debridement sessions was 3.74 +/- 0.69 in group 1 versus 1.82 +/- 0.34 in group 2. CONCLUSIONS: Early exploration and debridement in equivocal (early) FG has a better clinical outcome with reduced hospital stay and number of debridement sessions than conservative treatment with delayed debridement. PMID- 27695530 TI - Nivolumab in the treatment of advanced renal cell carcinoma: clinical trial evidence and experience. AB - Renal cell carcinoma (RCC) is considered an immunogenic tumor with a prominent dysfunctional immune cell infiltrate, unable to control tumor growth. Cytokine based immunotherapies, including interferon-alpha and interleukin-2, have been used for the treatment of metastatic RCC (mRCC). Long-term responses and complete remissions were observed, but durable clinical benefit efficacy in the overall population was limited and associated with significant toxicity. As a consequence, new generation agents targeting the vascular endothelial growth factor (VEGF) and mammalian target of rapamycin (mTOR) pathways replaced interferon alpha (IFN-alpha). Strategies of tumor immune evasion include T-cell suppression by negative signals deriving from the interaction between programmed death-1 (PD-1) on the T cell and its ligand (PDL-1) on the tumor cells. Nivolumab, a programmed death 1 checkpoint inhibitor, blocks this pathway, thus reversing T-cell suppression and activating antitumor responses. The aim of this review is to summarize the safety and efficacy data of nivolumab in mRCC. Objective responses and safety profile of single-agent nivolumab are favorable in both previously treated and treatment-naive mRCC patients. Despite toxic effects, combination therapies with nivolumab have shown promising results, indicating a potential role in the treatment of mRCC. Tailoring immunotherapy on a patient-to patient basis represents a major challenge for the future. PMID- 27695532 TI - Role of endoscopic third ventriculostomy in tuberculous meningitis with hydrocephalus. AB - Hydrocephalus is one of the commonest complications of tuberculous meningitis (TBM). It can be purely obstructive, purely communicating, or due to combinations of obstruction in addition to defective absorption of cerebrospinal fluid (CSF). Endoscopic third ventriculostomy (ETV) as an alternative to shunt procedures is an established treatment for obstructive hydrocephalus in TBM. ETV in TBM hydrocephalus can be technically very difficult, especially in acute stage of disease due to inflamed, thick, and opaque third ventricle floor. Water jet dissection can be helpful in thick and opaque ventricular floor patients, while simple blunt perforation is possible in thin and transparent floor. Lumbar peritoneal shunt is a better option for communicating hydrocephalus as compared to VP shunt or ETV. Intraoperative Doppler or neuronavigation can help in proper planning of the perforation to prevent neurovascular complications. Choroid plexus coagulation with ETV can improve success rate in infants. Results of ETV are better in good grade patients. Poor results are observed in cisternal exudates, thick and opaque third ventricle floor, acute phase, malnourished patients as compared to patients without cisternal exudates, thin and transparent third ventricle floor, chronic phase, well-nourished patients. Some of the patients, especially in poor grade, can show delayed recovery. Failure to improve after ETV can be due to blocked stoma, complex hydrocephalus, or vascular compromise. Repeated lumbar puncture can help faster normalization of the raised intracranial pressure after ETV in patients with temporary defect in CSF absorption, whereas lumbar peritoneal shunt is required in permanent defect. Repeat ETV is recommended if the stoma is blocked. ETV should be considered as treatment of choice in chronic phase of the disease in obstructive hydrocephalus. PMID- 27695531 TI - Quantitative determination of betamethasone sodium phosphate and betamethasone dipropionate in human plasma by UPLC-MS/MS and a bioequivalence study. AB - The compound medicine of betamethasone sodium phosphate (BSP) and betamethasone dipropionate (BDP) is widely used for diverse glucocorticoid-sensitive acute and chronic diseases such as asthma, rheumatoid arthritis and systemic lupus erythematosus. It will be useful and beneficial to validate sensitive method for the determination of BSP, BDP and their metabolites for their pharmacokinetic study. Hereby, an ultra-high pressure liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) has been validated for the determination of BSP, BDP and their metabolites betamethasone (BOH), betamethasone 17-monodipropionate (B17P) and betamethasone 21-monodipropionate (B21P) in human plasma. Liquid liquid extraction with ether and n-hexane (v/v, 4:1) was used for sample preparation of BDP, BOH, B17P and B21P with beclomethasone dipropionate as internal standard (IS), while solid phase extraction was adopted for sample preparation of BSP using prednisolone as IS. The chromatographic separation was performed on a Hypurity C18 column (150 mm*2.1 mm, 5 MUm) for BOH, BDP, B21P and B17P, and a Luna C18 (2) column (150 mm*2.0 mm, 5 MUm) for BSP. Electrospray ionization interfaced with positive multiple reaction monitoring (MRM) scan mode was used for mass spectrometric detection. The standard calibration curves were linear within the range of 2.525 * 10-9-403.9 * 10-9 mol.dm-3 for BSP, 0.125 * 10 9-55.81 * 10-9 mol.dm-3 for BDP, 0.278 * 10-9-74.95 * 10-9 mol.dm-3 for BOH, 0.098 * 10-9-4.688 * 10-9 mol.dm-3 for B17P and 0.226 * 10-9-5.411 * 10-9 mol.dm 3 for B21P, respectively. The validated method was successfully applied to a bioequivalence study in 23 healthy subjects after they were injected with this compound medicine BSP and BDP. PMID- 27695529 TI - Oxidation-reduction potential of semen: what is its role in the treatment of male infertility? AB - The diagnosis of male infertility relies largely on conventional semen analysis, and its interpretation has a profound influence on subsequent management of patients. Despite poor correlation between conventional semen parameters and male fertility potential, inclusion of advanced semen quality tests to routine male infertility workup algorithms has not been widely accepted. Oxidative stress is one of the major mediators in various etiologies of male infertility; it has deleterious effects on spermatozoa, including DNA damage. Alleviation of oxidative stress constitutes a potential treatment strategy for male infertility. Measurement of seminal oxidative stress is of crucial role in the identification and monitoring of patients who may benefit from treatments. Various tests including reactive oxygen species (ROS) assay, total antioxidant capacity (TAC) assay or malondialdehyde (MDA) assay used by different laboratories have their own drawbacks. Oxidation-reduction potential (ORP) is a measure of overall balance between oxidants and antioxidants, providing a comprehensive measure of oxidative stress. The MiOXSYSTM System is a novel technology based on a galvanostatic measure of electrons; it presents static ORP (sORP) measures with static referring to the passive or current state of activity between oxidants and antioxidants. Preliminary studies have correlated sORP to poor semen qualities. It is potentially useful in prognostication of assisted reproductive techniques outcomes, screening of antioxidants either in vivo or during IVF cycles, identification of infertile men who may benefit from treatment of oxidative stress, and monitoring of treatment success. The simplified laboratory test requiring a small amount of semen would facilitate clinical application and research in the field. In this paper, we discuss the measurement of ORP by the MiOXSYS System as a real-time assessment of seminal oxidative stress, and argue that it is a potential valuable clinical test that should be incorporated into the male infertility workup and become an important guide to the treatment of oxidative stress-induced male infertility. PMID- 27695534 TI - Posttraumatic delayed tension pneumocephalus: Rare case with review of literature. AB - Pneumocephalus is commonly seen after head and facial trauma, ear infections, and tumors of the skull base or neurosurgical interventions. In tension pneumocephalus, the continuous accumulation of intracranial air is thought to be caused by a "ball valve" mechanism. In turn, this may lead to a mass effect on the brain, with subsequent neurological deterioration and signs of herniation. Tension pneumocephalus is considered a life-threatening, neurosurgical emergency burr-hole evacuation was performed and he experienced a full recovery. However, more invasive surgery was needed to resolve the condition. Delayed tension pneumocephalus is extremely rare and considered a neurosurgical emergency. Pneumocephalus is a complication of head injury in 3.9-9.7% of the cases. The accumulation of intracranial air can be acute (<72 h) or delayed (>=72 h). When intracranial air causes intracranial hypertension and has a mass effect with neurological deterioration, it is called tension pneumocephalus. We represent a clinical case of a 30-year-old male patient with involved in a road traffic accident, complicated by tension pneumocephalus and cerebrospinal fluid rhinorrhea on 1 month after trauma and underwent urgent surgical intervention. Burr-hole placement in the right frontal region, evacuation of tension pneumocephalus. Tension pneumocephalus is a life-threatening neurosurgical emergency case, which needs to undergo immediate surgical intervention. PMID- 27695535 TI - Spinal epidural angiolipomas: Clinical characteristics, management and outcomes. AB - PURPOSE: The spinal epidural angiolipomas are rare expansive processes made of mature lipomatous and angiomatous elements. They often have a benign character. Their etiology, pathogenesis remains uncertain, and it is a cause of spinal cord compression. The magnetic resonance imaging is the most important neuroradiological examination. Histological examination is the only examination to confirm the diagnosis. Surgery is the treatment of choice. METHODS: A retrospective study of all patients operated on for a spinal epidural angiolipoma at the Department of Neurosurgery at the National Institute of Neurology of Tunis between January 2000 and December 2014 (15 years) was performed. The aim of this study is to describe the clinical, radiological, histological characteristics and the treatment of this tumor. RESULTS: A total of nine patients were operated from January 01, 2000 to November 30, 2014. The average age of our patients was 51 years with ages that ranged from 29 to 65 with a male predominance. The period between onset of symptoms and diagnosis ranged from 24 months with an average 12 months. Posterior localization of the tumor was seen in all patients. Surgical resection was performed for all cases. The postoperative course has been satisfactory, with a complete recovery of neurological functions in all patients. CONCLUSIONS: The spinal epidural angiolipomas is rare expansive process causing spinal cord compression. Treatment is exclusively surgical resection. The functional outcome of spinal epidural angiolipomas is particularly favorable with a complete neurological recovery is if the patient was quickly operated. PMID- 27695536 TI - High incidence of neural tube defects in Northern part of India. AB - BACKGROUND: In the absence of primary care and prevailing associated social stigma, many patients of neural tube defects (NTDs) from remote areas die without getting any treatment. The high number of such untreated cases and unregistered deaths in these areas made us ponders to the fact that tertiary care center-based studies do not represent the true incidence of NTDs. MATERIALS AND METHODS: We did a population-based survey for NTDs births of rural areas from Jaunpur to Ghazipur district in Eastern Uttar Pradesh. These districts are among the least developed areas of Northern India in Uttar Pradesh among other 17. RESULTS: The data show an incidence of 7.48 per 1000 live births. CONCLUSION: Besides of unawareness regarding periconceptional folate supplementation, intensive effort is required to design adequately powered studies to search other key factors responsible for high prevalence of NTDs. PMID- 27695537 TI - Comparison of computational fluid dynamics findings with intraoperative microscopy findings in unruptured intracranial aneurysms- An initial analysis. AB - CONTEXT: The increase in the detection of unruptured cerebral aneurysms has led to management dilemma. Prediction of risk based on the size of the aneurysm is not always accurate. There is no objective way of predicting rupture of aneurysm so far. Computational fluid dynamics (CFDs) was proposed as a tool to identify the rupture risk. AIMS: To know the correlation of CFD findings with intraoperative microscopic findings and to know the relevance of CFD in the prediction of rupture risk and in the management of unruptured intracranial aneurysms. SETTINGS AND DESIGN: A prospective study involving nine cases over a period of 6 months as an initial analysis. SUBJECTS AND METHODS: Both males and females were included in the study. Preoperative analysis was performed using computed tomography angiogram, magnetic resonance imaging in all cases and digital substraction angiogram in some cases. Intraoperatively microscopic examination of the aneurysm wall was carried out and images recorded. The correlation was done between microscopic and CFD images. RESULTS: Seven cases were found intraoperatively to have a higher risk of rupture based on the thinning of the wall. Two cases had an atherosclerotic wall. All cases had low wall shear stress (WSS).Only two cases with atherosclerotic wall had a correlation with low WSS. CONCLUSIONS: While the pressure measured with CFD technique is a good predictor of rupture risk, the WSS component is controversial. Multicentric trials involving a larger subset of population are needed before drawing any definite conclusions. On-going development in the CFD analysis may help to predict the rupture chances accurately in future. PMID- 27695538 TI - Wall-to-lumen ratio of intracranial arteries measured by indocyanine green angiography. AB - BACKGROUND: The wall-to-lumen ratio (WLR) is an important parameter in vascular medicine because it indicates the character of vascular wall as well as the degree of stenosis. Despite the advances in medical imaging technologies, it is still difficult to measure the thin-walled normal intracranial arteries, and the reports on the WLR of normal intracranial artery are limited. It might be possible to calculate the WLR using the indocyanine green (ICG) angiography, which is used to observe intracranial vessels during microsurgery. PURPOSE: To evaluate the WLR of normal intracranial arteries using ICG angiography. MATERIALS AND METHODS: From the three cases in which ICG angiography was recorded with a ruler during microsurgery, 20 measurement points were chosen for the analysis. The ICG was injected intravenously with a dose of 0.2 mg/kg, and the vessels were inspected at high magnification using an operating microscope equipped with near infrared illumination system. The vessel outer diameter and the luminal diameter were measured using the images before and after the ICG arrival based on the pixel ratio method using a ruler as reference, respectively. The WLR was calculated as 0.5 * (vessel outer diameter - vessel luminal diameter). RESULTS: The WLR (mean +/- standard deviation) of normal intracranial arteries was 0.086 +/- 0.022. The WLR tended to be high in small arteries. CONCLUSION: The WLR of normal intracranial arteries calculated using ICG angiography was consistent with the WLR reported in the previous reports based on human autopsy. PMID- 27695533 TI - Chronic subdural hematoma. AB - Chronic subdural hematoma (CSDH) is one of the most common neurosurgical conditions. There is lack of uniformity in the treatment of CSDH amongst surgeons in terms of various treatment strategies. Clinical presentation may vary from no symptoms to unconsciousness. CSDH is usually diagnosed by contrast-enhanced computed tomography scan. Magnetic resonance imaging (MRI) scan is more sensitive in the diagnosis of bilateral isodense CSDH, multiple loculations, intrahematoma membranes, fresh bleeding, hemolysis, and the size of capsule. Contrast-enhanced CT or MRI could detect associated primary or metastatic dural diseases. Although definite history of trauma could be obtained in a majority of cases, some cases may be secondary to coagulation defect, intracranial hypotension, use of anticoagulants and antiplatelet drugs, etc., Recurrent bleeding, increased exudates from outer membrane, and cerebrospinal fluid entrapment have been implicated in the enlargement of CSDH. Burr-hole evacuation is the treatment of choice for an uncomplicated CSDH. Most of the recent trials favor the use of drain to reduce recurrence rate. Craniotomy and twist drill craniostomy also play a role in the management. Dural biopsy should be taken, especially in recurrence and thick outer membrane. Nonsurgical management is reserved for asymptomatic or high operative risk patients. The steroids and angiotensin converting enzyme inhibitors may also play a role in the management. Single management strategy is not appropriate for all the cases of CSDH. Better understanding of the nature of the pathology, rational selection of an ideal treatment strategy for an individual patient, and identification of the merits and limitations of different surgical techniques could help in improving the prognosis. PMID- 27695539 TI - Factors affecting outcome in poor grade subarachnoid haemorrhage: An institutional study. AB - CONTEXT: Poor grade subarachnoid hemorrhage (SAH) is usually associated with unfavorable outcomes and optimal management is deemed complicated. Most centres follow an expectant management strategy or a less aggressive approach till patients improve to good clinical grades. This approach has been associated with higher mortality and morbidity. However, not all patients with poor clinical condition fare badly. Identification and early aggressive management of this select group of patients may lead to favorable outcomes. SETTINGS AND DESIGN: Prospective non-randomized study. MATERIALS AND METHODS: We prospectively analyzed 19 cases presented in WFNS grade 4 and 5 and factors affecting their outcome at a tertiary care centre in south India. This study was aimed at identifying those few poor grade patients who are probable candidates for a good outcome. STATISTICAL ANALYSIS USED: All the variables were analyzed for possible correlations with the SPSS version 13 software. The Chi-square test with a P < 0.05 was taken as statistically significant. RESULTS: Of 19 cases, 13 were operated and good outcome was seen in 53.8% of the patients who underwent surgery and aggressive management. All 7 patients who were managed conservatively died. 15.8% of the patients had low density changes (P = 0.625). Absence of such changes was associated with a good long term outcome (P = 0.004). 9 patients had intraventricular hemorrhage at presentation and 5 patients having hydrocephalus underwent extra-ventricular drainage. Statistically significant factors precluding good outcome were the presence of infarcts and thick SAH in the cisterns. CONCLUSIONS: Poor grade (WFNS 4 and 5) SAH patients with or without ICH, IVH, if operated within 3 days can give rise to favorable outcome in around 50%. However, presence of patchy infarcts associated with thick subarachnoid blood (Fisher grade 3) precludes long term survival or meaningful recovery. Hence, aggressive management is unlikely to alter the natural history of such patients. PMID- 27695540 TI - Comprehension and compliance with the discharge advice and quality of life at home among the postoperative neurosurgery patients discharged from PGIMER, Chandigarh, India. AB - PROBLEM STATEMENT: Neurosurgical patients require special care not only in the hospital but also after their discharge from the hospital. Comprehension and compliance to the instructions given by the doctors/nurses at the time of discharge is important in home care of these patients. Many such patients suffer from various co-morbidities. Variable periods of convalescence affect health related quality of life in these patients. PURPOSE OF THE STUDY: To determine the degree of compliance of neurosurgery patients and their family caregivers with the discharge advice given by the consultantsTo evaluate the quality of life of these patientsTo know the problems faced by these patients at home. MATERIALS AND METHODS: This cross-sectional interview-based descriptive study was conducted in 2010 in Chandigarh. These patients were visited at their home. A scale was evolved to evaluate comprehension and compliance to the advice given at the time of discharge, according to the criteria developed by Clark et al. Lawton Brody instrumental activity of daily life and Spitzer quality of life index were used to assess patients' quality of life after the operation. Verbatim responses were recorded for the purpose of qualitative research. RESULTS: Overall, 58 patients and their caregivers were interviewed at home. Mean age of the patients was 38.9 years. Out of 37 patients, 35 showed good comprehension and 33 patients had a good compliance with the instructions given for medication. The condition of 74.1% patients improved after the operation. Depression was reported in 31% of the patients. Many (36.2%) patients had to quit their job due to the disease. Almost half (47.4%) of the patients were independent in daily activities of their life while being evaluated on Barthel activity of daily life index. CONCLUSION AND RECOMMENDATIONS: It is in the long term that the true complexity and impact of operations become apparent. After operation, such patients are likely to have a range of physical, emotional, cognitive, behavioral, and social problems, which may result in difficulties for both patients and their family caregivers. Provision of mechanism of prioritized follow-up care to the operated bedridden neurosurgery patients should be made. PMID- 27695541 TI - Evaluation of modified Kumar and Kalra myelopathy scoring system in sub-axial spinal pathologies. AB - BACKGROUND: Various pathologies affect the spine, but these lesions present with more or less similar clinical profile. The present functional scoring systems are inadequate and insensitive to changes in neurological status of the patient. OBJECTIVE: Our study aims to assess the modified Kumar and Kalra (K and K) scoring system in patients with pathologies in the sub-axial spine. MATERIALS AND METHODS: A total of 78 consecutive patients from the period of January 2009 to June 2010 were prospectively included in the study. These patients were operated by the senior author at our institute. The mean Modified Japanese Orthopaedic Association (MJOA) score and the mean modified K and K score were calculated in the preoperative, at the time of discharge (post-surgery), and at 3 months and 6 months follow-up. RESULTS: There were 57 male (73.01%) patients and 21 female patients (26.92%), with the mean age of presentation of 39.20 years (+/-14.12 years) and a range of 9-75 years. Out of the total 78 patients, 60 patients had pathology in the cervical spine (sub-axial spine) and 18 patients had pathology in the dorsal spine. Majority of the patients had motor and sensory symptoms. The mean preoperative modified K and K score was 17.38 (+/-3.18) and the mean preoperative MJOA score was 11.21 (+/-2.12). The K and K score was able to predict the correct outcome in 70 patients (89.74%), whereas the MJOA score was able to predict correctly in 62 patients (79.49%). CONCLUSION: The modified K and K score has a better predictive value than the MJOA score. PMID- 27695542 TI - Intracranial abscesses: Retrospective analysis of 32 patients and review of literature. AB - BACKGROUND: Intracranial abscess collections, though uncommon, are dreaded complications of head trauma, neurosurgical operations, meningitis, and otogenic, mastoid, and paranasal air sinus infections. Combining surgical evacuation with the appropriate antibiotic therapy is the effective treatment for intracranial abscesses. However, literature on surgical treatment is replete with several procedures which, on their own, may not. OBJECTIVES: To determine the epidemiology and outcomes (of various treatment modalities) of intracranial abscesses in our institution, a major referral center for neurosurgical conditions in the midwestern region of Nigeria. MATERIALS AND METHODS: This is a retrospective analysis of demographic data as well as indications, treatment modalities, and outcomes of various surgical procedures for evacuation of intracranial abscesses between September 2006 and December 2011. RESULTS: We carried out 40 procedures in 32 (23 male and 9 female) patients with various intracranial abscesses. These represented approximately 5.6% of all operative neurosurgical procedures in our unit since inception. Most abscesses [16, i.e. 50%] occurred in the second decade. In the first decade, there were 7 (22%), and after the age of 30 years, there were 4 (12.5%). The most susceptible single year of life was infancy with 4 (12.5%) cases of intracranial abscesses. None of the infants had features of congenital heart disease. The predisposing factors were mostly otolaryngologic (9) or posttraumatic (6). Most abscesses (41%) were located in the frontal region, and intraparenchymal (i.e. intracerebral or intracerebellar) (50%) lesions were commoner than extradural, subdural, or intraventricular lesions. The commonest procedure performed (50%) was burr hole evacuation. Four patients (12.5% of cases) died. Prognosis appears to worsen with meningitis as the predisposing infection, ventriculitis, multiple abscesses especially in infants, and immunosuppression. CONCLUSION: The relative rarity of intracranial abscesses and the frequent delays in making the diagnosis render the condition a significant challenge to the clinician. A high index of suspicion, close interaction between the neurosurgeon and infectious disease specialist, with early treatment by adequate abscess drainage and appropriate antimicrobial treatment are important in their management. PMID- 27695543 TI - Traumatic tentorial hematoma in two-wheeler riders: Correlation with helmet use. AB - BACKGROUND: Tentorial hematoma is frequently seen in traumatic brain injury (TBI) patients, especially in motorized two-wheeler riders following head injury. However its relevance and prognostic significance are not known. OBJECTIVE: To evaluate patients of TBI with tentorial hematoma using a simple grading system and attempt to correlate this grading with factors like helmet use and neurological outcome. MATERIALS AND METHODS: This prospective study over a 1-year period included patients with TBI who had tentorial hematoma in the initial plain head. Patients were divided into three grades based on the initial CT findings: Grade I: Isolated tentorial hematoma, grade II: tentorial hematoma with midline shift but open cisterns and grade III: Tentorial hematoma with effaced cisterns. Clinical and radiological records of patients including admission GCS and GOS at discharge were assessed in all cases. OBSERVATIONS: A total of 1786 patients of TBI were admitted during the study period. Of these, 106 (5.9%) patients had tentorial hematoma. 84.9% (n = 90) were male and 15.1% (n = 16) were female with the mean age being 36.5 years (range 2-66 years). The mean admission GCS was 13, 11 and 8 in patients with grade I, II and III tentorial hematoma respectively. 43.4% (n = 46) of the patients had grade I, 32.1% (n = 34) had grade II and 24.5% (n = 26) patients had grade III tentorial hematoma. Seventy-one patients (84.5%) were riding motorized two wheelers with 63 (89%) wearing helmets. The majority of the patients wearing helmets (58.8%) had grade I hematoma with 35% (n = 22) having grade II hematoma and only 6.3% (n = 4) having grade III hematoma. Overall, there were 20 deaths. 50% (n = 10) of the deaths were in patients with grade III hematoma and 40% (n = 8) of the deaths were in patients with grade II hematoma. There were two (10%) deaths in patients with grade I hematoma (both unrelated to head injury). The mean GOS at the time of discharge was 5, 4.1 and 2.2 in patients with grade I, II and III tentorial hematoma, respectively. CONCLUSIONS: Tentorial hematomas are very common in two-wheeler riders with TBI and could be a marker for indirect forces such as rotational forces experienced while wearing helmets. PMID- 27695544 TI - Role of effective canal diameter in assessing the pre-operative and the post operative status of patients with bony cranio-vertebral anomalies. AB - INTRODUCTION: The effective canal diameter (ECD) for the cranio-vertebral junction is measured from the posterior surface of the dens to the nearest posterior bony structure (foramen magnum or the posterior arch of the atlas). The ECD is the space which is occupied by the buffer space (which can be compromised without producing any signs or symptoms) and the cord itself. We intend to study the role of the ECD (especially in patients with markedly reduced ECD) in producing the symptoms and also the outcome of surgery in patients with bony cranio-vertebral junction (CVJ) anomalies. MATERIALS AND METHODS: A total of 67 consecutive patients from the period of January 2009 through June 2010 were prospectively included in the study. These patients were operated by a single experienced surgeon (the senior author) at the Sanjay Gandhi Post Graduate Institute of Medical Sciences, Lucknow. The ECD and the pre-operative Kumar and Kalra score (K and K score) (4) was calculated for all patients. The K and K score was also calculated at the time of discharge, at three months and six months follow-up. The patients were divided into three groups based on the ECD into 5 mm to 10 mm group, 10 mm to 15 mm group, and >15 mm group. RESULTS: There were 53 male (79.1%) patients and 14 female patients (20.9%) with mean age of presentation 27.10 years (+/-15.01 years) with range of 4-59 years. The duration of symptoms in our series varied from 1-120 months with mean of 23.79 months. The mean effective canal diameter was 9.027 mm (+/-2.23 mm) with range of 5-16 mm. The mean pre-operative K and K score was 19.27 (+/-4.19). There were 39 patients who had an ECD between 5 mm to 10 mm, 24 patients with ECD between 10 mm to 15 mm, and 4 patients with ECD more than 15 mm. The correlation coefficients between the effective canal diameter and the pre-operative and the post-operative Kumar and Kalra score at the time of discharge, 3 months and 6 months were 0.404 (P < 0.001), 0.320 (P < 0.008), 0.0302 (P < 0.013), and 0.284 (P < 0.020), respectively. The ECD and the pre-operative score were most significantly and strongly related to each other in patients with ECD between 5-10 mm. CONCLUSION: The ECD is significantly related to the pre-operative status (K and K score) of the patient. This correlation was strongest in the group with ECD of 5-10 mm. It was also observed that as the follow-up increased, the correlation between the ECD and the post-operative K and K score became less stronger though they remained significantly related to each other. PMID- 27695545 TI - Facial functional outcome in monitored versus not-monitored patients in vestibular schwannomas surgery. AB - OBJECTIVE: Even though advances in surgical techniques have improved facial nerve outcomes, functional preservation is still an issue because injury to the facial nerve has significant physical and psychological consequences for the patient. We retrospectively review our data in VS surgery to compare the facial outcome in intraoperative facial monitored versus not-monitored patients. MATERIALS AND METHODS: 51 consecutive patients with unilateral vestibular schwannoma in the period from 2005 to 2010 were treated in our Institution. In according to the type of neurophysiological tool used during surgical procedures, two patients groups were identified: Group 1 (facial stimulator only) and Group 2 (stimulator and facial monitoring). Statistical comparison of the two groups was made with the t- test, and facial function results were evaluated with the Fisher's exact test. RESULTS: In the Group 1, of the 22 patients with anatomically preserved facial nerves, 3 (13.6%) showed excellent facial nerve function, 14 (63.6%) showed intermediate function, and 5 (22.7%) showed poor function. In the Group 2, all the 27 patients got anatomically preserved facial nerves, and 18 (66.7%) showed excellent facial nerve function, 9 (33.3%) showed intermediate function, and no one showed poor function. CONCLUSIONS: We found that retrosigmoid approach associated with continuous EMG facial monitoring combined with the use of bipolar stimulation is a safe and effective treatment for vestibular schwannomas. PMID- 27695547 TI - Localized reversible high signal intensities on diffusion-weighted MRI in hypoglycemia: A study of 70 cases. AB - INTRODUCTION: It is well-known that localized reversible high signal intensities in the splenium of the corpus callosum or the basal ganglia appear on diffusion weighted MRI in the presence of hypoglycemia. The aim of this study was to clarify the incidence and significance of such high signal intensity lesions. RESULTS: We analyzed 70 cases of hypoglycemia with consciousness disturbance referred to our outpatient office. Localized reversible high signal intensities on diffusion-weighted MRI were noted in 6 cases (8.6%). They were at the splenium of the corpus callosum in four cases (5.7%), and right frontal cortex and bilateral frontal white matter in one each. Convulsions were noted in five cases, and right hemiparesis was noted in three. None of the three cases of hemiparesis showed localized reversible high signal intensities on diffusion-weighted MRI. These lesions are reversible if the patients undergo treatment without delay. CONCLUSION: The significance of these lesions is still unclear. However, when a high signal intensity lesion that is not reasonable for the symptom is detected on diffusion-weighted MRI, an immediate check of the blood sugar level is mandatory. PMID- 27695546 TI - Ganglioglioma: Single-institutional experience of 24 cases with review of literature. AB - BACKGROUND: Ganglioglioma is a common seizure associated tumor. The goal of this study was to observe the postoperative outcome in patients with gangliogliomas. MATERIAL AND METHODS: A total 24 patients with gangliogliomas who underwent surgery at our institute from 2008 to 2011 were included. There were 13 males (54%) in our study. A retrospective analysis for the demographic profile, surgery and outcome was performed using STATA software. Literature on this subject was also reviewed, MEDLINE and PUBMED databases were searched. OBSERVATIONS: Sixteen patients presented with signs and symptoms of raised intracranial pressure and 12 patients had seizure disorder. Average age at surgery was 20 years (range 7-50 years). Twelve each were located in the temporal lobe and extra-temporal location. Intra-operative electrocorticography (ECoG) alone in three and image guidance alone were used in two patients, respectively. Both ECoG and image guidance were used in one patient and none of them was used in 18 patients. Gross total resection was achieved in 17 patients. After a mean follow-up of 1.6 years (range 3 months to 2.5 years), out of 12 patients with preoperative seizures, 10 (83.3%) were seizure free (Engel class-I) and 2 (16.6%) belonged to Engel class II. None of the factors, including age at surgery, seizure duration prior to surgery, type of seizures, use of intra-operative ECoG and image guidance, extent of tumor resection, and surgical strategy proved to have significant correlation with postoperative seizure outcome. CONCLUSIONS: Surgical treatment is effective and safe for patients with gangliogliomas. Neither intra-operative ECoG nor image guidance necessarily leads to better seizure control, although they are useful adjunct for achieving safe and complete tumor resection. PMID- 27695548 TI - A cost effectiveness based safety and efficacy study of resterilized intra parenchymal catheter based intracranial pressure monitoring in developing world. AB - BACKGROUND: The management of traumatic brain injury (TBI) aims to maintain the normal cerebral perfusion in spite of the mass lesions that may occur (haematoma, contusion, and oedema). The monitoring of the intracranial pressure (ICP) is a step in that direction. The intra-parenchymal catheters have the lowest incidence of infection compared to intra-ventricular/subdural catheters with reliable and accurate pressure recordings. The major disadvantage of the intra-parenchymal catheters is the cost, especially in developing nations. HYPOTHESIS: Resterilized intra-parenchymal strain gauge catheters can be used safely for ICP monitoring without any added risk of meningitis. The reusage of catheters can bring down the costs. Resterilized catheters/equipment have been approved for usage in cardiac usage, but such study on ICP catheters has not been carried out so far in any part of the world. METHODOLOGY: A total of 100 consecutive cases of severe TBI receiving ICP monitoring at a level 1 trauma center of a developing nation were prospectively studied (34 cases had fresh catheters, and 66 had resterilized [using ethylene oxide] catheters). OBSERVATIONS: The use of reused resterilized catheters was not associated with increased incidence of meningitis or fever (the surrogate marker for infection in this study). Also, there was concordance between the pressure recording of reused catheters and operative finding/subsequent computed tomography scans. These catheters after sterilization could be reused 2-4 times and reliably recorded the ICP (insignificant drift) with no increase in the incidence of meningitis. CONCLUSIONS: Usage of resterilized intra-parenchymal ICP catheters is feasible, safe, efficacious, and cost effective and brings down the cost of monitoring significantly. PMID- 27695549 TI - Learning neuroendoscopy with an exoscope system (video telescopic operating monitor): Early clinical results. AB - CONTEXT: Steep learning curve is found initially in pure endoscopic procedures. Video telescopic operating monitor (VITOM) is an advance in rigid-lens telescope systems provides an alternative method for learning basics of neuroendoscopy with the help of the familiar principle of microneurosurgery. AIMS: The aim was to evaluate the clinical utility of VITOM as a learning tool for neuroendoscopy. MATERIALS AND METHODS: Video telescopic operating monitor was used 39 cranial and spinal procedures and its utility as a tool for minimally invasive neurosurgery and neuroendoscopy for initial learning curve was studied. RESULTS: Video telescopic operating monitor was used in 25 cranial and 14 spinal procedures. Image quality is comparable to endoscope and microscope. Surgeons comfort improved with VITOM. Frequent repositioning of scope holder and lack of stereopsis is initial limiting factor was compensated for with repeated procedures. CONCLUSIONS: Video telescopic operating monitor is found useful to reduce initial learning curve of neuroendoscopy. PMID- 27695550 TI - Prolonged bradycardia, asystole and outcome of high spinal cord injury patients: Risk factors and management. AB - BACKGROUND: High spinal cord injury (HSCI) is one of the devastating traumatic injuries. 80% of these patients are young male, and 93% will have major neurological disabilities. There is a paucity of literature about prolonged bradycardia in HSCI patients. The aim of this study was to know the prevalence, risk factors, precipitating factors for prolonged bradycardia in the HSCI patients. MATERIALS AND METHODS: All patients who were admitted to the Intensive Care Unit (ICU) of a tertiary hospital, with spinal cord injury above level of dorsal (D4) were enrolled in this study prospectively. Patient's demographic data, mechanism, level and type of spinal injury, associated injuries, injury severity score (ISS), spinal shock, vasopressors used, time of occurrence of bradycardia, treatment for bradycardia, precipitating as well as risk factors and outcome were recorded. RESULTS: During the study period, a total of 138 patients were admitted to the ICU with HSCI. Majority of patients were male. The most frequently associated injury in these patients was skeletal fractures (38.4%). Most common complication was pneumonia 56 (41%). Forty-five (33%) of the total patients had prolonged bradycardia; 87% of these patients had pneumonia when bradycardia occurred. 53.4% had cardiac asystole. 29 (21%) patients had bradycardia at the time of endotracheal suctioning, whereas 27 (20%) patients developed bradycardia at the time of positioning. Majority of the patients were managed conservatively. Those HSCI patients who developed prolonged bradycardia, their ISS score was statistically higher, ICU and hospital stay was significantly higher compared with those HSCI patient who did not have prolonged bradycardia. Multivariate analysis revealed that hypotension on admission; pneumonia, and tracheostomy were risk factors for the development of prolonged bradycardia in HSCI patients. CONCLUSION: Prolonged bradycardia was associated with significantly higher incidence of asystole. Endotracheal suctioning and positioning of HSCI patients were significant provocative factors for prolonged bradycardia; hypotension on admission, pneumonia and tracheostomy were the risk factors for the development of prolonged bradycardia in these patients. PMID- 27695552 TI - Primary spinal tumors in childhood: A single institution 15 year experience. AB - BACKGROUND: Pediatric primary spinal tumors (PST) are fairly uncommon, with little available data regarding incidence and outcomes. MATERIALS AND METHODS: We conducted a retrospective review of the 22 consecutive patients less than 18 years old diagnosed with PST between March 1997 and May 2011 and treated at Chang Gung Children Hospital. All patients had undergone magnetic resonance imaging (MRI) for pre-operative evaluation and operations for PST. The extent of tumor removal was assessed by surgical report by the neurosurgeon or by post-operative MRI if available. RESULTS: Ten of them had intramedullary tumors and 12 had intradural extramedullary tumors. All patients were treated with surgery to the primary site. A total of 15 patients underwent gross total tumor resection and seven patients received post-operative radiotherapy. Five patients received adjuvant chemotherapy for their primary tumor. Fourteen patients (64%) survived from study entry without tumor progression. CONCLUSIONS: PST encompassed a diverse group of pathologic entities that differ markedly based on the location and age of the children. Total resection of pediatric PST in children could be performed with acceptable risk and satisfactory long-term results.

AB - CONTEXT: Many reconstructive techniques have been proposed to prevent postoperative cerebrospinal fluid (CSF) leakage after trans-sphenoidal pituitary surgery. However, no total agreement has been reached to the best technique. AIM: Assessment of the efficacy of sellar repair with autologous muscle and composite septal cartilage grafts for treatment of intraoperative and delayed postoperative CSF leakage following trans-sphenoidal pituitary surgery without the use of postoperative external lumbar CSF drain. STUDY DESIGN: This is a retrospective case series study, level IV evidence. MATERIALS AND METHODS: : Twenty three patients were involved in this study. Seventeen patients had intraoperative CSF leakage and were treated immediately by our technique. Six patients had postoperative CSF rhinorrhea and had delayed treatment with our technique after failure of conservative measures and external lumbar CSF drainage for more than three days. The technique involved intradural placement of autologous muscle graft supplemented with extradural composite septal cartilage graft, composed of a piece of the posterior cartilaginous septum with its covering mucoperichondrium on one side only to fit into the sellar defect as a double layer button. RESULTS: CSF leak was of grade 1 in 6 patients (26.1%), grade 2 in 10 patients (43.5%) and grade 3 in 7 patients (30.4%). None of the patients in our study had postoperative CSF leak after the use of our technique during the follow up period (mean 24 +/- 10.47 standard deviation months). None of the patients developed treatment-related complications. All the patients had well developed mucosal covering of the sellar defect after two months. CONCLUSION: Our technique of sellar repair by using autologous muscle and composite septal cartilage grafts is effective in treatment of intraoperative and delayed postoperative CSF leakage following trans-sphenoidal pituitary surgery without the use of postoperative external lumbar CSF drain even in the high-output CSF leaks. PMID- 27695553 TI - Primary non-Hodgkin's lymphoma of the skull with extra and intracranial extension presenting with bulky scalp mass lesion. AB - Primary non-Hodgkin's lymphoma (NHL) of the cranium with extra- and intracranial extension without systemic or skeletal manifestation in a non-immunocompromised patient is extremely rare. These lesions are most of the time misdiagnosed because they mimic other conditions like meningioma. Here, we report a case presented with huge bulky scalp mass which on magnetic resonance imaging (MRI) brain showed involvement of scalp, cranial vault, meninges, and the brain parenchyma, mimicking a meningioma. After gross total resection, biopsy and CD marker study revealed primary non-Hodgkin's diffuse large B-cell lymphoma (DLBCL). Malignant NHL should be considered in differential diagnosis of bulky scalp mass lesion. PMID- 27695554 TI - Primary aneurysmal bone cyst of the petrous temporal bone: A case report and review of literature. AB - Aneurysmal bone cyst (ABC) arising in the petrous portion of the temporal bone is a rare entity with only five such reported cases in the literature. We report the case of a 28-year-old man who presented with a tender swelling in the right preauricular region with right ear discharge and conductive hearing loss of 4 years' duration. Computed tomography and Magnetic Resonance imaging showed a destructive lesion in the right petrous bone with cavitation consistent with the diagnosis of ABC. Gross total resection of the lesion was achieved and diagnosis was confirmed histologically. The patient had no recurrence at 12 months of follow-up. This report presents the unusual location of an uncommon bony tumor with a review of its clinical, radiological, and histopathological features as well as the treatment modalities available. PMID- 27695555 TI - Calvarial tubercular osteomyelitic abscess in an elderly. AB - Tuberculous osteomyelitis of skull is very rare, even in areas where tuberculosis is endemic. We herein describe an elderly woman who was apparently immunocompetent and presented with left frontal scalp swelling and right cervical lymphadenopathy. CT scan showed irregular bony destruction of the frontal bone. MRI revealed a large extradural, multiseptate, solid-cystic lesion with peripheral enhancement. FNAC from the lesion showed granulomas with caseation suggestive of tuberculosis. The lesion was debrided and she was started on anti tubercular therapy. Deterioration of liver parameters led to change from primary drugs to liver-friendly, anti-tubercular agents. Though anti-tubercular therapy is the mainstay of calvarial tuberculosis, surgical debridement reduces the bacterial burden and probably hastens recovery.

We present a patient with post-traumatic bilateral facial and abducens palsy. There were bitemporal fractures that did not correspond with the facial canal. Despite complete facial palsy with axonal degeneration and > 90% facial muscle degenervation, conservative management helped. This report highlights the importance of conservative management in post-traumatic complete facial palsy especially when the fracture line does not correspond with the facial canal. PMID- 27695557 TI - Baastrup's disease in the pediatric spine. AB - Baastrup's disease is an uncommon entity in the elderly spine and it is very rare in the pediatric age group. There are only few case reports in the literature containing Baastrup's disease in pediatric spine. Baastrup's disease is also known as kissing spine because the posterior spinous processes touch or "kiss" one another, characterized by enlarged posterior spinous projections with normal neuroforamina and normal spinal disk height. There are various pathological and etiological hypotheses behind Baastrup's disease. Backache is one of the most common causes of morbidity in these patients and but sometimes patient can be asymptomatic with or without swelling on the back. Here, we present a case of 10 year-old female child with silent swelling on low back region diagnose as Baastrup's disease. PMID- 27695558 TI - Delayed intracerebellar hemorrhage secondary to lumboperitoneal shunt insertion. AB - Aim of this paper is to present and discuss a case of a delayed cerebellar parenchymal hemorrhage developing after L/P shunt placement with a NPH patient. A hypertensive patient admitted to our clinic with a diagnosis of NPH. The patient was placed a pressure adjustable L/P shunt without any surgical complication. He was discharged with an uneventful period. The patient was admitted to the emergency clinic of our hospital with a 1.5 * 1.5 cm diameter hematoma at the left cerebellar hemisphere on 2 days after his discharge. CSF drainage by an L/P shunt can generate intracerebellar hemorrhages especially in hypertensive patients. PMID- 27695559 TI - Lymphoplasmacyte-rich meningioma with invasion of bone: A case report and review of literature. AB - Lymphoplasmacyte-rich (LPR) meningioma is a rare variant of meningioma, which is characterized by conspicuous infiltration of plasma cells and lymphocytes and a variable proportion of meningothelial elements, and is classified as a grade I tumor in World Health Organization (WHO) classification of tumors of central nervous system. The origin and biological behavior of this rare variant of meningioma is still not clear. Till date, very few cases of LPR meningioma have been reported globally. Here, we are presenting a case of right parietal convexity LPR meningioma with invasion of bone in a 32-year-old male patient, who presented to us with complaints of focal seizures and weakness in left upper limb. PMID- 27695560 TI - Late onset of subdural hematoma after bifrontal contusion. AB - Cerebral cortical contusions are one of the most common computed tomography findings in head-injured patients and common sequel of traumatic brain injury. These contusions tend to show a progressive increase in mass effect on repeated imaging, most small contusions do not require surgical evacuation. However, progression to subdural hematoma (SDH) in a late aspect is unique. Here we present a 71-year-old man with bifrontal contusion, who deteriorated 43 days after initial trauma with sudden onset of acute SDH. This unusual case suggests that neurosurgeons should be alert for the possibility of very late onset of acute SDH after bifrontal contusions. PMID- 27695562 TI - Postoperative seizure following transforaminal percutaneous endoscopic lumbar discectomy. AB - Endoscopic surgery for lumbar disc herniation has been available for more than 30 years. Transforaminal percutaneous endoscopic lumbar discectomy is a well-known, safe, and effective method used for the treatment of the lumbar disc herniation. The published complications of the transforaminal percutaneous endoscopic lumbar discectomy consist of infections, thrombophlebitis, dysesthesia, dural tear, vascular injury, and death. Seizure after transforaminal percutaneous endoscopic lumbar discectomy is an extremely rare complication. A 20-year-old patient applied at our department who had undergone transforaminal percutaneous endoscopic lumbar. During the procedure, while performing the discography, non ionic contrast media was administered into the thecal sac inadvertently. Two hours after surgery, the patient developed generalized tonic-clonic seizure of 5 min duration. Diagnosis of iohexol-induced seizure was made and the patient was treated supportively without anti-epileptics. Here we present the first case of seizure after transforaminal percutaneous endoscopic lumbar discectomy, which was caused by inadvertent administration of the contrast media into the thecal sac. PMID- 27695561 TI - Solitary fibrous tumor of the sellar region treated with adjuvant radiation therapy. AB - The solitary fibrous tumor of central nervous system is rare. Herein, a case of solitary fibrous tumor arising from sellar region is described. A 60-year-old man underwent subtotal excision of the tumor because of extensive infiltration of optical and vascular structures. In view of the presence of residual tumor, he was treated with adjuvant radiation therapy. After a follow-up period of 1 year, there was no progression of the lesion evident on magnetic resonance imaging of the brain. Solitary fibrous tumor should be considered as one of the differential diagnosis of a mass lesion arising in sellar region. Immunohistochemistry with CD34 is valuable for discerning the diagnosis. Complete surgery should be the goal of treatment and adjuvant radiation therapy may be considered for residual or recurrent disease. PMID- 27695563 TI - Osteoblastic meningioma with turtle shell: Different entity from calcified meningioma. AB - Bone formation within meningioma is secondary to metaplasia of the meningothelial cells into osteoblastic cells. This needs to be differentiated form the commonly seen calcification. We describe a rare case of osteobalstic meningioma in which bony trabeculae were seen within meningothelial cells. PMID- 27695564 TI - Recurrence of spinal schwannoma: Is it preventable? AB - Spinal schwannomas account for about 25% of primary intradural spinal cord tumors in adult. The prognosis for spinal schwannomas is excellent in most cases. Complete resection is curative. However following subtotal removal, recurrence develops after several years. We describe a case of recurrent spinal schwannoma who had been operated twice before for same disease. The possible cause of recurrence and difficulties in reoperation are discussed. PMID- 27695565 TI - Coexistent dysembryoplastic neuroepithelial tumour and pilocytic astrocytoma. AB - Dysembryoplastic neuroepithelial tumour (DNET) is an uncommon mixed glioneuronal tumour. DNET is classified as Grade I neoplasm in revised World Health Organization classification of tumors of the nervous system. DNET is commonly seen in the temporal lobe of children and young adults with features of pharmacoresistant complex partial seizures. Tumors arising in association with DNETs are rare. Only two cases of pilocytic astrocytoma (PA) arising in DNETs are reported. Surgical excision is the only successful management with favourable prognosis. The development of recurrence and malignancy after subtotal or even after complete excision challenges the premise of stability and highlights the importance of close clinical follow up. Here, a case of DNET with area of PA is described which helps in understanding the pathogenesis and biological behavior of DNET. PMID- 27695566 TI - A case of symptomatic synchronous cervical and cerebellar metastasis after resection of thoracal metastasis from temporal glioblastoma multiforme without any local recurrence. AB - Glioblastoma multiforme (GBM) is the most common and the most malignant primary intracranial tumor in adults and it is usually occurs between the age of 40 and 60 years. It is local invasive and recurrent tumor and hence that has a poor prognosis. However, recent advances in tumor surgery, irradiation and chemotherapeutic agent permit long survival and metastasis which is symptomatic. Previously studies reported spinal metastasis, but we report a first case of synchronous symptomatic cerebellar and cervical spinal metastasis after resection of symptomatic thoracic spinal metastasis from temporal GBM without any recurrence of excision areas. PMID- 27695567 TI - Anterior cervical discectomy and fusion with titanium cages for simple or multilevel herniated discs and spur of the cervical spine: Report of 2 cases and experience in Bali. AB - This report presents two cases of cervicobrachialgia and radiculopathy due to multiple cervical herniated discs and spur formation that dealt with anterior cervical discectomy and fusion (ACDF) using different titanium interbody cages. The description of the clinical presentation, magnetic resonance imaging (MRI) appearances and management strategy are discussed. Both cases showed chronic neck pain and radiating pain from the shoulder to the arm. They had a history of blurry vision, cluster head ache, weakness, and numbness on the shoulder for 2 years. MRI revealed multiple herniated discs between C4-7 and accompanied by the spur formation leading to the narrowness of the spinal canal and its foramina bilaterally. ACDF were performed and complete decompression of the spinal canal and its foramina were carried out. Twin M-cages (Ammtec Inc.-Japan) were placed in the first case at C5-7 levels and single cage of Smith Robinson (SR) was placed in the second case at C5-6 levels. There were no more blurry vision, cluster headache, weakness, and numbness, immediately after surgery. To our knowledge, this is the first reported cases of ACDF, using twin M-cages and single SR cage in Indonesia, with improvement immediately after surgery. Cervical spondylosis can present with cervicobrachialgia and radiculopathy and surgical treatment produces good functional outcome. PMID- 27695568 TI - Papillary tumor of pineal region: A rare entity. AB - Pineal tumors comprise 0.4 - 1.0% of intracranial space-occupying lesions in adults. Papillary tumor of pineal region (PTPR) is a very rare entity. It has been newly described in WHO 2007 classification of brain tumors. Only a few case reports are available in the literature. We report a case of a 60 year-old female presenting with headache, giddiness and reduced vision. Imaging studies showed a pineal mass with areas of hemorrhage. All ventricles were normal. There was a past history of a pineal gland tumor excised 2 years ago. This case is being reported for its rarity and aggressiveness in the form of recurrence. Limited/available immunohistochemistry workup has been done. PMID- 27695569 TI - Nocardia farcinica abscess of the cerebellum in an immunocompetent patient: A case report and review of the literature. AB - Nocardial brain abscesses are uncommon and rarely occur in patients without predisposing factors. They may be mistaken for gliomas or necrotic metastases, and surgical intervention may be required to make the diagnosis. We report the first case of Nocardia farcinica cerebellar abscess in a patient without immunosuppression. He presented to us with headache and instability beginning a week before. Brain magnetic resonance imaging (MRI) revealed a cystic lesion located at the right cerebellar hemisphere, hypointense in T1 and hyperintense in T2, with a fine wall that enhanced after injection of gadolinium. Image tests also showed a cavitated lesion at the upper lobule of the right lung. The patient underwent craniotomy and drainage of the cerebellar abscess. Initial post operative treatment with linezolid produced a limited response. He was re operated and vancomycin, imipenem and ciprofloxacin were added with an excellent outcome of the cerebellar and lung lesions.

Ganglioglioma shares biologic features with neurofibromatosis leading to suggestions that the co-existence of the two diseases may be more than coincidental. We report a case of ganglioglioma of the conus medullaris in a patient of neurofibromatosis and explore the possible association of the two diseases. PMID- 27695571 TI - Resolution of aspergillosis in neuroimaging of an immunocompromised patient with pulmonary and cerebral lesions. AB - Central nervous system (CNS) aspergillosis is uncommon and considered the most lethal form of aspergillosis. Indeed, current therapeutic strategies such as combination antifungal regimen, neurosurgical resection of infected tissue, and removal of infection source fail to improve the unsatisfactory prognosis of CNS aspergillosis in the majority of the patients. The authors describe a case of chronic pulmonary aspergillosis with concomitant CNS lesions that dramatically responded to antifungal therapy and the CNS lesions resolved in follow-up imaging. PMID- 27695572 TI - Solid cystic trigeminal schwannoma with intraorbital extension causing proptosis and vision loss. AB - Schwannomas are slowly growing, well capsulated, benign tumors. Involvement of vestibular nerve is most commonly followed by trigeminal nerve. Trigeminal schwannoma is rare entity, and cystic degeneration with intraorbital extension of trigeminal schwannoma is even rarer. These tumors occur in fourth and fifth decades of life and patients have variable presentation depending on which cranial compartment is involved. Orbital schwannoma usually presents with proptosis with or without vision loss. We are reporting such a rare case of solid cystic trigeminal schwannoma with intraorbital extension through superior orbital fissure that was removed surgically. PMID- 27695573 TI - Traumatic bilateral basal ganglia bleed: A report of rare two cases and review of the literature. AB - Traumatic basal ganglia hemorrhage (TBGH) is relatively uncommon. Bilateral basal ganglia hematoma after trauma is extremely rare and is limited to case reports. We report two cases of traumatic bilateral basal ganglia hemorrhage and review the literature in brief. Both cases were managed conservatively. The general incidence of TBGH is reported between 2.4% and 3% of closed head injury. However, the incidence is higher in postmortem studies (9.8%). Bilateral traumatic basal ganglia hematoma is extremely rare. Descriptions are limited to case reports. PMID- 27695574 TI - Primary central nervous system teratoma with sarcomatous transformation in a young girl: Report of a rare case. AB - A 13-year-old girl presented with chief complaints of severe headache and vomiting followed by hemiparesis. Radiological examination suggested a space occupying lesion in the right parietal lobe. Craniotomy and debulking of the tumor mass were done. Histopathological and subsequent immunohistochemical examination showed a tumor composed of fascicle of atypical spindle cells which revealed reactivity to vimentin with interspersed areas of well-differentiated cartilage tissue. Hence, the diagnosis of teratoma with sarcomatous transformation was given. Detailed discussion including review of literature has been made regarding different aspect of the tumor. PMID- 27695575 TI - Peripheral nerve lipoma: Case report of an intraneural lipoma of the median nerve and literature review. AB - Adipose lesions rarely affect the peripheral nerves. This can occur in two different ways: Direct compression by an extraneural lipoma, or by a lipoma originated from the adipose cells located inside the nerve. Since its first description, many terms have been used in the literature to mention intraneural lipomatous lesions. In this article, the authors report a case of a 62-year-old female who presented with an intraneural median nerve lipoma and review the literature concerning the classification of adipose lesions of the nerve, radiological diagnosis and treatment.

PMID- 27695577 TI - Malignancies Trends in a Hispanic Cohort of HIV Persons in Puerto Rico before and after cART. AB - BACKGROUND: The study describes the cancer trends in a Puerto Rican Hispanic HIV/AIDS cohort for three different time periods as defined by the availability of combination antiretroviral therapy (cART) in the Island: pre (1992-1995), early (1996-2002, and recent (2003-2009). METHODS: AIDS and non-AIDS related malignancies risk, standardized incidence rate and one year mortality was evaluated in the cohort before and after cART. RESULTS: Of the 281 malignancies found in 265 persons; 72% were in men, 38% in injecting drug users and 42.3% were AIDS related cancers. AIDS related cancer standardized incidence rates decreased significantly in the cART eras; however, Kaposi's sarcoma and invasive cervical carcinoma incidence remained significantly higher in the cohort when compare to the general population. On the contrary, non-AIDS related cancer standardized incidence rates increased significantly in the cART eras, specifically those of the oral/cavity/pharynx, liver, anus, vaginal, and Hodgkin's and non-Hodgkin's Lymphomas. Around 50% of the persons with cancers were reported dead within the first year of their diagnoses without a significant variation during the cART eras. CONCLUSION: The higher incidence of Kaposi's sarcoma, invasive cervical carcinoma and non-AIDS related malignancies and their high mortality in the cART eras is suggestive of the role of oncogenic viruses, environmental agents, risky lifestyle behaviors and inadequate cancer prevention efforts that contribute and accelerate the risk of malignant transformation in these subjects. Aggressive intervention in the form of vaccines, risky practice reduction, early screening, early treatment and adequate risk reduction education needs to be incremented in this vulnerable population. PMID- 27695578 TI - Power and Effective Study Size in Heritability Studies. AB - Correlation between study units in quantitative genetics studies often makes it difficult to compare important inferential aspects of studies. Describing the relatedness between study units is critical to capture features of pedigree studies involving heritability, including power and precision of heritability estimates. Blangero et al (2012) showed that in pedigree studies the power to detect heritability is a function of the true heritability and the eigenvalues of the kinship matrix. We extend this to a more general setting which allows statements about expected precision of heritability estimates. Using two different Taylor series approximations, we summarize the relatedness in a study design by one or two parameters. These relatedness summary parameters (RSPs) are functions of the eigenvalues or log-eigenvalues of the kinship matrix. Using the RSPs based on the log-eigenvalues, we accurately approximate the expectation of the likelihood ratio test and expected confidence interval widths. We define an effective sample size of a target study as one which has the equivalent power and precision to a reference design. Using unrelated sibpairs as the reference design provides very accurate assessments of power. RSPs and effective sample sizes provide new tools for comparing studies and communicating information about relatedness in heritability studies. PMID- 27695579 TI - Variations in Sexual Identity Milestones among Lesbians, Gay Men and Bisexuals. AB - Despite a large body of literature covering sexual identity development milestones, we know little about differences or similarities in patterns of identity development among subgroups of the lesbian, gay, and bisexual (LGB) population. For this study, we assessed identity milestones for 396 LGB New Yorkers, ages 18-59. Sexual identity and disclosure milestones, were measured across gender, sexual identity, race/ethnicity, and age cohort subgroups of the LGB sample. Men experienced most sexual identity milestones earlier than women, but they tended to take more time between milestones. LGBs in younger age cohorts experienced sexual identity milestones and disclosure milestones earlier than the older cohorts. Bisexual people experienced sexual identity and disclosure milestones later than gay and lesbian people. Timing of coming out milestones did not differ by race/ethnicity. By comparing differences within subpopulations, the results of this study help build understanding of the varied identity development experiences of people who are often referred to collectively as "the LGB community." LGB people face unique health and social challenges; a more complete understanding of variations among LGB people allows health professionals and social service providers to provide services that better fit the needs of LGB communities. PMID- 27695581 TI - Survival after partial and radical nephrectomy for high-risk disease: A propensity-matched comparison. AB - INTRODUCTION: Increasingly, partial nephrectomy has been applied to high-risk disease without evidence that its survival benefits can be extrapolated to this entity. We aimed to compare overall survival after partial vs. radical nephrectomy in patients with high-risk renal cell carcinoma. METHODS: Using the National Cancer Data Base, we identified patients who underwent partial or radical nephrectomy for high-risk disease between 2003 and 2006. High-risk disease was defined as the presence of adverse pathological features within the primary tumour, namely high-grade or unfavourable histology, T3 stage, or both. After matching the partial and radical nephrectomy groups based on propensity scores, 1680, 276, and 76 patients with high-grade or unfavourable histology, T3 stage, or both adverse pathologic features, respectively, were available for analysis. Five-year overall survival was compared after partial vs. radical nephrectomy for each high-risk cohort using the Kaplan-Meier and log rank tests. RESULTS: Partial nephrectomy was associated with a statistically significant improvement in five-year overall survival compared to radical nephrectomy for small tumours (median size 3.0 cm; interquartile range 2.1-4.5 cm) with high grade or unfavourable histology (87% vs. 81%; p<0.01) or with pT3a stage (82% vs. 71%; p<0.01). For patients concomitantly harbouring both adverse pathologic features, no difference in survival was detected (p=0.21). CONCLUSIONS: Partial nephrectomy is associated with survival benefits in patients with adverse pathologic features, suggesting that renal preservation is not only safe, but also potentially beneficial for high-risk disease. Due to inherent selection bias associated with partial nephrectomy use, prospective validation of these findings is needed. PMID- 27695580 TI - Mechanisms of Individual Differences in Impulsive and Risky Choice in Rats. AB - Individual differences in impulsive and risky choice are key risk factors for a variety of maladaptive behaviors such as drug abuse, gambling, and obesity. In our rat model, ordered individual differences are stable across choice parameters, months of testing, and span a broad spectrum, suggesting that rats, like humans, exhibit trait-level impulsive and risky choice behaviors. In addition, impulsive and risky choices are highly correlated, suggesting a degree of correlation between these two traits. An examination of the underlying cognitive mechanisms has suggested an important role for timing processes in impulsive choice. In addition, in an examination of genetic factors in impulsive choice, the Lewis rat strain emerged as a possible animal model for studying disordered impulsive choice, with this strain demonstrating deficient delay processing. Early rearing environment also affected impulsive behaviors, with rearing in an enriched environment promoting adaptable and more self-controlled choices. The combined results with impulsive choice suggest an important role for timing and reward sensitivity in moderating impulsive behaviors. Relative reward valuation also affects risky choice, with manipulation of objective reward value (relative to an alternative reference point) resulting in loss chasing behaviors that predicted overall risky choice behaviors. The combined results are discussed in relation to domain-specific versus domain-general subjective reward valuation processes and the potential neural substrates of impulsive and risky choice. PMID- 27695582 TI - Urothelial-based reconstructive surgery for upper- and mid-ureteral defects: Long term results. AB - INTRODUCTION: Ureteral strictures can result in obstructive nephropathy and renal function deterioration. Surgical management of ureteral defects, especially in the proximal- and mid-ureter, is particularly challenging. Our purpose was to analyze the long-term outcomes of urothelial-based reconstructive surgery for upper- and mid-ureteral defects. METHODS: We conducted a retrospective analysis of a single tertiary centre's database, including 149 patients treated for ureteral defects between 2001 and 2011. Thirty-one patients (21%) underwent complex urothelial-based surgical repairs for upper- and mid-ureter defects. Patients' median age was 61 years. The mean length of the ureteral strictures was 2.5 cm, located in upper-, mid-ureter, or in between in 19 (61%), 10 (32%), and two (6%) patients, respectively. All patients were treated with a primary urothelial-based repair. Median followup time was 26 months. The primary outcome of the study was the long-term preservation of renal function and lack of clinical obstruction. The secondary endpoint of the study was the assessment of the intra- and postoperative complication rates. RESULTS: Most of the lesions were benign (22, 71%), while nine strictures (29%) were malignant. Seven patients (23%) suffered from postoperative complications, five of which were infectious. The median pre- and postoperative calculated glomerular filtration rates were 66 ml/min/1.72m2 and 64ml/min/1.72m2, respectively. Success rate was 84%, defined as lack of need for re-operation or kidney drainage at the last followup. CONCLUSIONS: Upper- and mid-ureteral defects present a complex pathology necessitating experienced reconstructive surgical skills. Our data suggest good long-term results for primary urothelial-based reconstructions for these pathologies. PMID- 27695583 TI - Prospective investigation of penile length with newborn male circumcision and second to fourth digit ratio. AB - INTRODUCTION: We prospectively investigated the relationship between newborn male circumcision (NMC) and second to fourth digit ratio with penile length. METHODS: As participants for our study, we identified already circumcised young patients who visited our hospital for urological treatment. The age at which the circumcision had been done was assessed. The patients' height and weight were measured. Second to fourth digit ratio was calculated by measuring the second and fourth digit lengths. The flaccid and erectile penile lengths were measured from the base of the penis to the tip of the glans in standing position. RESULTS: A total of 248 patients were included in our study. In univariate analysis, height, second to fourth digit ratio, flaccid penile length, and age of circumcision were associated with erectile penile length. Among these variables, second to fourth digit ratio, flaccid penile length, and age of circumcision were significant predictive factors for erectile penile length in multivariate analysis. The subjects were divided into two groups, including 72 patients in the NMC group and 176 patients in the non-NMC group. No significant difference was found in height, weight, and second to fourth digit ratio between both groups. However, flaccid (p<0.001) and erectile (p=0.001) penile lengths were shorter in the NMC group than in the non-NMC group. CONCLUSIONS: Despite the small number of subjects, this study shows that NMC was associated with shorter penile length. Second to fourth digit ratio, flaccid penile length, and age of circumcision were also significant predictive factors for erectile penile length. Further multicentre studies with larger number of subjects and biochemical analyses are needed for potential clinical applicability. PMID- 27695584 TI - Metabolic syndrome in patients with prostate cancer undergoing intermittent androgen-deprivation therapy. AB - INTRODUCTION: The presence of metabolic syndrome in men with prostate cancer (PCa) undergoing androgen-deprivation therapy (ADT), especially intermittent type, has not been completely evaluated. The aim of this study is to evaluate metabolic syndrome in men with PCa undergoing intermittent ADT. METHODS: In this longitudinal study, we studied the prevalence of metabolic syndrome and its components in 190 patients who were undergoing intermittent ADT. The metabolic syndrome was defined according to the Adult Treatment Panel III criteria. All metabolic parameters, including lipid profile, blood glucose, blood pressures, and waist circumferences of the patients were measured six and 12 months after treatment. RESULTS: Mean age of the patients was 67.5 +/- 6.74 years. The incidence of metabolic syndrome after six and 12 months was 6.8% and 14.7%, respectively. Analysis of various components of the metabolic syndrome revealed that patients had significantly higher overall prevalence of hyperglycemia, abdominal obesity, and hypertriglyceridemia in their six- and 12-month followups, but blood pressure has not been changed in the same period except for diastolic blood pressure after six months. CONCLUSIONS: Although there was an increased risk of metabolic syndrome in patients receiving intermittent ADT, it was lower than other studies that treated the same patients with continuous ADT. Also it seems that intermittent ADT has less metabolic complications than continuous ADT and could be used as a safe alternative in patients with advanced and metastatic PCa.

PMID- 27695586 TI - Ovarian vein thrombosis: A complication of percutaneous nephrolithotomy. AB - The medical and surgical complications of percutaneous nephrolithotomy (PCNL) are well-known, including deep venous thrombosis. Ovarian vein thrombosis (OVT) is a rare, but potentially serious type of venous thrombosis that has not previously been reported as a complication of PCNL or ureteral stent placement. We report a case of OVT associated with ureteral stenting following a tubeless PCNL. This complication was successfully managed conservatively without any short- or long term sequelae. PMID- 27695587 TI - Concurrent use of endourological and radiologic methods in the management of high grade renal trauma. AB - This case report explores the efficacy of simultaneous use of endourological and radiological methods to assess and manage high-grade renal trauma. A male rugby player was diagnosed with Grade 4 blunt renal trauma. A segment of the patient's kidney was isolated from the main renal pelvis with intact perfusion. This resulted in urinary extravasation. Ureteral stenting and angioembolization were used to treat the patient's severe symptoms. Angioembolization ablated functional tissue that was causing a persistent urinary leak. Following the treatment, the patient was discharged with no significant bleeding or leakage from the kidney. This report illustrates an uncommon use of this combined approach. Followup 18 months post-trauma revealed normal blood pressure and approximately 30% loss of volume of the affected kidney. PMID- 27695588 TI - Multidisciplinary approach to giant paratesticular liposarcoma. AB - Primary paratesticular tumours are very rare and the spermatic cord (SCT) is the most frequent site of origin, with 20% of malignancy. Although liposarcoma is the most frequent histotype (46.6 %), less than 200 cases have been reported in the literature. We report the case of a 56-year-old man who presented a giant scrotal mass of 25 years of evolution and measuring 40 * 40 cm. It could be considered the greatest paratesticular liposarcoma described to date. Computed tomogaphy (CT) revealed mass features consistent with liposarcoma and the simultaneous presence of bilateral inguinal hernia with bladder involvement. A multidisciplinary approach was taken to remove the mass, solve the hernia, and provide functional results. PMID- 27695589 TI - Ectopic Cushing's syndrome due to retroperitoneal ACTH-producing paragangliomas. AB - Extra-adrenal pheochromocytomas, or paragangliomas, are rare tumours that derive from extra-adrenal chromaffin cells. Cushing's syndrome (CS) caused by paragangliomas is extremely rare. We report a 53-year-old man with hypertension, diabetes, and symptoms of hypokalemia. Computer tomography (CT) revealed two retroperitoneal masses and bilateral adrenal hyperplasia. Together with the laboratory examinations, ectopic CS caused by multiple paragangliomas was highly suspected. The patient underwent resections of retroperitoneal tumours, left kidney, and left adrenal; postoperative histopathology confirmed two paragangliomas that were both positively stained for adrenocorticotropic hormone (ACTH). He got clinical and biochemical recoveries without any recurrent evidence at the nine-month followup. PMID- 27695590 TI - Isolated thrombosis of right spermatic vein with underlying Factor V Leiden mutation. AB - Spermatic vein thrombosis is a very uncommon clinical entity. Most cases involve the left side. Herein, we present an unusual case of a young man who presented with spermatic vein thrombosis on the right side with an underlying Factor V Leiden mutation. To our knowledge, it is the first case in the literature. PMID- 27695591 TI - Correction in supplement data. AB - [This corrects the article on p. S144 in vol. 10.]. PMID- 27695592 TI - The Western snip, stitch, and tug hydrocelectomy: How I do it. AB - INTRODUCTION: Adult idiopathic hydrocele is a common benign disorder that merits surgical correction when symptomatic. The most popular techniques for repair are plication (Lord's procedure) or excision and eversion of the tunica vaginalis (Jaboulay procedure). Established complications from these traditional repairs include hematoma, recurrence, and infection. These procedures are performed through a scrotal incision. We describe a novel technique of hydrocele repair with gubernaculum preservation through a subinguinal incision. METHODS: The novel technique is described in detail. A retrospective review was performed of those patients treated by a single surgeon with the subinguinal technique. Demographic information, indication for treatment, success rate, and details regarding complications were collected. RESULTS: We term the technique the "Snip, Stitch & Tug" repair. Through a small subinguinal incision, the tunica is everted posterior to the spermatic cord and testis without resection of the hydrocele sac or division of the gubernaculum. Twelve patients with postoperative followup were identified. Eleven patients (92%) treated with the novel technique were cured. There was only one complication (superficial wound infection) recorded after this technique. CONCLUSIONS: Idiopathic hydrocele repair with gubernaculum preservation can be easily and safely performed through a small subinguinal incision. PMID- 27695593 TI - Statistical methods and computing for big data. AB - Big data are data on a massive scale in terms of volume, intensity, and complexity that exceed the capacity of standard analytic tools. They present opportunities as well as challenges to statisticians. The role of computational statisticians in scientific discovery from big data analyses has been under recognized even by peer statisticians. This article summarizes recent methodological and software developments in statistics that address the big data challenges. Methodologies are grouped into three classes: subsampling-based, divide and conquer, and online updating for stream data. As a new contribution, the online updating approach is extended to variable selection with commonly used criteria, and their performances are assessed in a simulation study with stream data. Software packages are summarized with focuses on the open source R and R packages, covering recent tools that help break the barriers of computer memory and computing power. Some of the tools are illustrated in a case study with a logistic regression for the chance of airline delay. PMID- 27695594 TI - Predictors of Prolonged Hospital Stay in Status Migrainosus. AB - BACKGROUND: Patients with status migrainosus often need to be admitted due to the severity of their headaches. Their hospitalization is often prolonged due to poor headache control. Large sample studies looking into the factors associated with prolonged length of stay (pLOS) in status migrainosus are lacking. METHODS: We utilized the Nationwide Inpatient Sample database to identify 4325 patients with primary discharge diagnosis of status migrainosus. Length of inpatient stay (LOS) of more than 6 days (90th percentile of LOS) was defined as pLOS. Patient demographics, hospital characteristics, mood disorders, anxiety disorder, and common medical comorbidities were identified. Multivariable logistic regression was used to identify factors associated with pLOS. RESULTS: We found 402 patients with pLOS. Female gender, African American race, mood disorder, obesity, opioid abuse, congestive heart failure, and chronic renal failure were significant independent predictors of pLOS. Median inflation-adjusted cost of hospitalization was USD$3829 (interquartile range: 2419-5809). CONCLUSION: We were able to identify several factors associated with pLOS in status migrainosus. Most of the factors we found were similar to those known to increase the prevalence and severity of migraine in the general population. Knowledge of these factors may help physicians identify high-risk patients to institute early migraine abortive and prophylactic treatment in order to shorten the length of hospital stay. PMID- 27695595 TI - International Classification of Diseases, Ninth Revision (ICD-9) Diagnosis Codes Can Identify Cerebral Venous Thrombosis in Hospitalized Adults. AB - BACKGROUND: Cerebral venous thrombosis (CVT) is a relatively rare and understudied disease. We sought to determine the accuracy of International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes to identify CVT. METHODS: Retrospective chart review using the electronic medical record (EMR) to identify all patients discharged with CVT following admission or emergency department visit from May 1, 2010 to May 1, 2015 at our center. RESULTS: We identified 111 patients with an ICD-9 discharge diagnosis code of 325.0 (cerebral sinovenous thrombosis, excluding nonpyogenic cases and cases associated with pregnancy and the puerperium), 437.6 (CVT of nonpyogenic origin), or 671.5 (CVT complicating pregnancy, childbirth, or the puerperium) in any position. Of these 111 patients, 84 (75.7%) had confirmed CVT after EMR review. Searching outpatient and radiology records, we found an additional 24 patients with CVT who were not identified via query of ICD-9 discharge diagnosis codes. The ICD-9 codes 325.0, 437.6, or 671.5 in any position had a combined sensitivity of 77.8% and specificity of 92.7%; in the primary position, they had a sensitivity of 28.7% and specificity of 98.3%. CONCLUSION: The ICD-9 codes 325.0, 437.6, and 671.5 can be used to identify CVT with acceptable sensitivity and specificity. PMID- 27695596 TI - Ziprasidone as a Potential Abortive Therapy for Status Migrainosus. AB - Migraine headache is among the most prevalent neurologic disorders. Status migrainosus often leads to hospitalization, and multiple medications are sometimes required for symptomatic relief. In 2008, neurologists at our institution started using the atypical antipsychotic ziprasidone as an abortive medication for status migrainosus. The Clinical Investigation Data Exploration Repository was used to search for patients admitted to the Barnes-Jewish Hospital inpatient neurology service with diagnoses of "headache" or "migraine." Patients were identified as having status migrainosus if they met the International Headache Society criteria for a migraine lasting >72 hours. Clinical records of identified patients were then entered into a secure online database (REDCap). Between 2008 and 2015, a total of 34 patients received 10 to 40 mg of ziprasidone for the treatment of status migrainosus. Among patients who received ziprasidone, headache severity decreased 5.68 +/- 3.0 points on a 10-point scale, from admission to discharge. Ziprasidone was the last abortive medication added prior to discharge in 65% of cases. The 30-day readmission rate for migraine headache in patients who received ziprasidone was 12%. Ziprasidone was well tolerated, with side effects limited to a mild dystonic reaction (n = 1), rhinorrhea (n = 1), and a prolonged QTc of 495 milliseconds (n = 1). This observational study suggests that ziprasidone may be a safe, effective abortive medication for the treatment of status migrainosus. Further studies comparing ziprasidone to standard of care are warranted. PMID- 27695597 TI - Continuous Qualitative Electroencephalography as a Noninvasive Neuromonitor. AB - Intracranial pressure (ICP) monitoring frequently guides key decisions in the management of diseases causing intracranial hypertension. Although typically measured by invasive means, contraindications may leave the clinician with little recourse for dynamic ICP evaluation-particularly when the patient's mental status is compromised. We describe here a healthy 18-year-old woman who subacutely progressed to coma due to diffuse cerebral venous sinus thrombosis. Heparinization precluded the use of invasive ICP monitoring, and electroencephalography (EEG) was used novelly as a surrogate ICP monitor. She responded well to anticoagulation and hyperosmolar therapy guided by qualitative EEG and was later discharged with a nearly normal neurologic examination. She was found to have Salmonella bacteremia, heterozygous prothrombin and factor V Leiden mutations, and hemoglobin H disease. PMID- 27695598 TI - Electrographic Correlates of Plateau Waves in Patients With Leptomeningeal Metastases. AB - We describe video electroencephalography (video-EEG) correlates of transient neurological attacks due to plateau waves-paroxysmal elevations in intracranial pressure-in patients with leptomeningeal metastases. We identified 3 patients with leptomeningeal metastases, intracranial hypertension, and transient neurological attacks captured on video-EEG without evidence of seizures or epileptiform activity. We identified all clinical events on video and reviewed the corresponding EEG data for evidence of abnormalities. All 3 patients had mild to moderate slowing and 2 had frontal intermittent rhythmic delta activity during background EEG recording. There were 33 clinical events recorded and stereotyped for each patient. All 33 events were associated with an increase in delta range slowing of >=30% compared to the background. This abnormality started <=2 minutes before the onset of clinical symptoms and persisted for minutes after clinical resolution. This study is the first to carefully describe the electrographic correlates of transient neurological attacks due to plateau waves in patients with leptomeningeal metastasis. Clinical attacks were consistently associated with a possible EEG signature of diffuse delta range slowing. Future studies can validate the sensitivity and specificity of these EEG changes as a prognostic and/or response biomarker in patients with leptomeningeal metastases with or without intracranial hypertension. PMID- 27695599 TI - Cefepime-Associated SIRPIDs in a Patient With Normal Renal Function. AB - Cefepime has been associated with encephalopathy and with nonconvulsive seizure activity, primarily in patients with renal impairment. Here, we report a case of cefepime-associated encephalopathy in a patient with normal renal function with stimulus-induced rhythmic activity seen on electroencephalogram, which resolved on discontinuation of cefepime. We bring this to the attention of the neurohospitalist community, as cefepime is widely used in the hospital setting, and cefepime-related neurotoxicity may go overlooked, especially in patients with normal renal function. Neurologists must recognize drug-related patterns, as the treatment is removing a medication rather than adding an antiepileptic medication. PMID- 27695600 TI - Human African Trypanosomiasis Encephalitis in the United States: Serial Magnetic Resonance Imaging. AB - It is important to recognize the signs and symptoms of human African trypanosomiasis (HAT) in order to facilitate early diagnosis and treatment. A 36 year-old man developed encephalitis caused by HAT. This encephalitis can appear many years after well-tolerated systemic infection. The neurologic manifestations developed 7 years after he had emigrated from Cameroon to the United States. We demonstrate the magnetic resonance imaging before, during, and after his treatment with intravenous eflornithine. Clinical signs and symptoms of HAT can be nonspecific and precede abnormalities on magnetic resonance imaging. Human African trypanosomiasis should be considered in the differential diagnosis of patients who have lived in sub-Saharan Africa and have a clinical presentation of subacute encephalitis. PMID- 27695601 TI - A 27-Year-Old Man With Right-Sided Hemiparesis and Dysarthria. PMID- 27695602 TI - A Case Study in the History of Neurology. AB - We review the case of a young man who developed a constellation of symptoms and signs-bizarre behavior, seizures, abnormal movements, and autonomic instability that evaded diagnosis at the time of presentation. We use this case to explore the way medical knowledge changes over time. Despite the dramatic advances in our understanding of neurological diseases in recent decades, physicians tend to approach diseases and diagnoses as if they were immutable. Our case reinforces how the diagnosis and treatment of disease are determined by an ever-changing historical context driven by the rapid expansion of medical knowledge. We discuss the implications of this realization and present strategies for navigating the boundaries of knowledge, both in practice and in principle. PMID- 27695603 TI - INTENSITY INHOMOGENEITY CORRECTION OF MACULAR OCT USING N3 AND RETINAL FLATSPACE. AB - As optical coherence tomography (OCT) has increasingly become a standard modality for imaging the retina, automated algorithms for processing OCT data have become necessary to do large scale studies looking for changes in specific layers. To provide accurate results, many of these algorithms rely on the consistency of layer intensities within a scan. Unfortunately, OCT data often exhibits inhomogeneity in a given layer's intensities, both within and between images. This problem negatively affects the performance of segmentation algorithms and little prior work has been done to correct this data. In this work, we adapt the N3 framework for intensity inhomogeneity correction, which was originally developed to correct MRI data, to work for macular OCT data. We first transform the data to a flattened macular space to create a template intensity profile for each layer giving us an accurate initial estimate of the gain field. N3 will then produce a smoothly varying field to correct the data. We show that our method is able to both accurately recover synthetically generated gain fields and improves the stability of the layer intensities. PMID- 27695604 TI - "I need to hear from women who have 'been there'": Developing a woman-focused intervention for drug use and partner violence in the emergency department. AB - OBJECTIVE: Addressing violence and linking women to community services in parallel with drug change goals is critical for women with coexisting intimate partner violence (IPV) and substance use disorders (SUD). Our objective was to develop a Web-based intervention to address violence and drug use among women patients in the ED. METHODS: The intervention was developed in a five-step process: 1) Initial intervention development based on selected theoretical frameworks; 2) In-depth interviews with the target population; 3) Intervention adaptation, with iterative feedback from further interviews; 4) Beta testing and review by an advisory committee of domestic violence advocates; 5) Acceptability and feasibility testing in a small open trial. RESULTS: Themes supported the selection of MI and empowerment models but also guided major adaptations to the intervention, including the introduction of videos and a more robust booster phone call. Participants in the open trial reported high scores for satisfaction, usability, and consistency with essential elements of motivational interviewing. CONCLUSIONS: This qualitative work with our target population of women in the ED with SUD experiencing IPV underscored the importance of connection to peers and empathetic human contact. We developed an acceptable and feasible intervention distinct from prior ED-based brief interventions for substance-using populations. PMID- 27695606 TI - A price comparison of recently launched proprietary pharmaceuticals in the UK and the US. AB - OBJECTIVE: To explore the relationship between prices charged by manufacturers of proprietary pharmaceuticals in the US and in the UK in recent years (2013-2016), expressed as a multiplier, and to detail to what extent this relationship differs for high-cost therapies used in smaller patient populations, as compared to lower cost drugs. METHODOLOGY: Therapies assessed by the Scottish Medicines Consortium (SMC) in the UK between 1 January 2013 and 1 June 2016 were identified; only in patent therapies were included in the analysis (to avoid the impact of price erosion post patent expiry); results were grouped according to annual cost per patient (whether considered high-cost, i.e., >L2,500 per patient per year, or not) and the size of the UK target population [whether considered orphan (<32,000 patients per year), ultra-orphan (<1,000 patients per year), or not]. Publicly listed prices were obtained in the US and UK and were adjusted where necessary to estimate the prices charged by manufacturers in the respective countries. The difference in price (per unit of the same strength and formulation) was calculated as a multiplier between the US and UK prices for each of the therapies identified. RESULTS: Based on the methodological approach described, 88 therapies were identified and included in the analysis. The multiplier between the US and UK prices was 3.64 for therapies with an estimated annual cost 32,000 down to <1,000, the US/UK price multipliers reduced from 2.13 for the former to 1.48 for the latter. CONCLUSION: Although pharmaceutical prices have been found to be on average substantially higher in the US compared to the UK, our findings suggest that this price discrepancy is smaller for higher-cost therapies targeting small patient populations. Manufacturers of high-cost products should therefore factor this in when formulating pricing strategies because the potential for higher pricing in the US seems greater for primary care products targeting large patient populations. PMID- 27695605 TI - Outcome of Adult Brain Tumor Consortium (ABTC) prospective dose-finding trials of I-125 balloon brachytherapy in high-grade gliomas: challenges in clinical trial design and technology development when MRI treatment effect and recurrence appear similar. AB - OBJECTIVES: The aim of this study is to define the maximal safe radiation dose to guide further study of the GliaSite balloon brachytherapy (GSBT) system in untreated newly diagnosed glioblastoma (NEW-GBM) and recurrent high-grade glioma (REC-HGG). GBST is a balloon placed in the resection cavity and later filled through a subcutaneous port with liquid I-125 Iotrex, providing radiation doses that diminish uniformly with distance from the balloon surface. METHODS: The Adult Brain Tumor Consortium initiated prospective dose-finding studies to determine maximum tolerated dose in NEW-GBM treated before standard RT or after surgery for REC-HGG. Patients were inevaluable if there was progression before the 90-day posttreatment toxicity evaluation point. RESULTS: Ten NEW-GBM patients had the balloon placed, and 2/10 reached the 90 day timepoint. Five REC-HGG enrolled and two were assessable at the 90-day evaluation endpoint. Imaging progression occurred before 90-day evaluation in 7/12 treated patients. The trials were closed as too few patients were assessable to allow dose escalation, although no dose-limiting toxicities (DLTs) were observed. Median survival from treatment was 15.3 months (95 % CI 7.1-23.6) for NEW-GBM and 12.8 months (95 % CI 4.2-20.9) for REC-HGG. CONCLUSION: These trials failed to determine a maximum tolerated dose (MTD) for further testing as early imaging changes, presumed to be progression, were common and interfered with the assessment of treatment-related toxicity. The survival outcomes in these and other related studies, although based on small populations, suggest that GSBT may be worthy of further study using clinical and survival endpoints, rather than standard imaging results. The implications for local therapy development are discussed. PMID- 27695607 TI - Male Infertility during Antihypertensive Therapy: Are We Addressing Correctly The Problem? AB - Male fertility significantly decreased in the last 50 years, as showed in several studies reporting a reduction of sperm counts per ml in the seminal fluid. Several "acute" pharmacological treatments, as antibiotics, could cause subclinical and temporary reduction of male fertility; conversely, long-term medical treatment may severely affect male fertility, although this effect could be considered transient in most of the cases. Thus, nowadays, several long-term pharmacological treatments may represent a clinical challenge. The association between several kind of antihypertensive drugs and reduction of male fertility has been showed in the mouse model, although the modification(s) which may alter this fine-regulated machinery are still far to be elucidated. Furthermore, well designed observational studies and randomized controlled trials are needed to accurately define this association in human model, meaning a narrative overview synthesizing the findings of literature retrieved from searches of computerized databases. We strongly solicit future human studies (both observational and randomized clinical trials) on large cohorts with adequate statistical power which may clarify this possible association and the effects (reversible or permanent) of each drug. Furthermore, we suggest a close collaboration between general practitioners, cardiologists, and andrologists in order to choose the most appropriate antihypertensive therapy considering also patient's reproductive desire and possible risk for his fertility. PMID- 27695608 TI - Aromatase Inhibitors for Endometriosis-Associated Infertility; Do We Have Sufficient Evidence? AB - Orally active aromatase inhibitors (AIs) have gained attention for treatment of infertile women with endometriosis in whom aromatase p450 is aberrantly expressed. This review aimed to critically appraise and summarize the available evidence concerning the use of AIs for management of endometriosis-associated infertility. PubMed was searched to May 2015 with the following key words: endometriosis, infertility and aromatase. Priority was given for randomized controlled trials (RCTs) followed by other study designs. Main outcome measures were as follows: rates of clinical pregnancy, miscarriage and live birth as well as endocrine outcomes. Eighty-two abstracts were screened and six original articles were included. A RCT demonstrated that post-operative letrozole treatment did not improve spontaneous pregnancy rate. Another RCT reported no superiority of letrozole superovulation over clomiphene citrate (each combined with intrauterine insemination) in minimalmild endometriosis and previous laparoscopic treatment. Anastrozole significantly inhibited the growth of endometriotic cells and their estrogen production in culture. In assisted reproductive technology (ART) cycles, dual suppression (Agonist/anastrozole) was tested in a pilot study with a pregnancy rate of 45% however, high pregnancy loss (30%) occurred. A retrospective study showed that letrozole may improve endometrial receptivity in endometriotic patients undergoing in vitro fertilization (IVF). An opposite view from an in vitro study showed lower estradiol production and aromatase expression in cultured granulosa cells from endometriotic women undergoing IVF and marked reduction under letrozole. In conclusion, current evidence is limited. More trials are warranted to enhance our knowledge and provide a clear and unequivocal evidence to guide our clinical management of infertile women with endometriosis using AIs. PMID- 27695609 TI - Prevalence of Infertility Problems among Iranian Infertile Patients Referred to Royan Institute. AB - BACKGROUND: Few studies have been conducted on the infertility problems in Iran. This study aimed to investigate the prevalence of infertility problems and related factors in Iranian infertile patients. MATERIALS AND METHODS: In this cross sectional study, 405 infertile patients referred to Royan Institute, Tehran, Iran, between 2014 and 2015, were selected by simple random sampling. Participants completed the Fertility Problem Inventory (FPI) including 46 questions in five domains (social concern, sexual concern, relationship concern, rejection of parenthood, and need for parenthood). Mean difference between male and female was verified using independent-samples Student's t test. A generalized linear model (GLM) was also used for testing the effect of variables on the fertility problems. Data was analyzed using Stata software version 13. RESULTS: The mean age (SD) of participants was 31.28 (5.42). Our results showed that 160 infertile men (95.23%) were classified as very high prevalence of infertility problems. Among infertile women, 83 patients (35.02%) were as very high prevalence of infertility problems, and 154 patients (64.98%) were as high prevalence. Age (P<0.001), sex (P<0.001), a history of abortion (P=0.009), failure of previous treatment (P<0.001), and education (P=0.014) had a significant relationship with FPI scores. CONCLUSION: Bases on the results of current study, an younger male with lower education level, history of abortion and history of previous treatments failure experienced more infertility problems. PMID- 27695610 TI - Assisted Reproductive Technology in Iran: The First National Report on Centers, 2011. AB - BACKGROUND: Due to the worldwide increase in infertility, it is both necessary and important to have assisted reproductive technology (ART) registries. In Iran, donation and surrogacy programs are approved by decrees from religious scholars. ART has been used since 1984 in Iran and the first Iranian infant conceived by gamete intra-fallopian transfer (GIFT) was born in 1989. This report, however, is the first national report on Iranian ART centers. MATERIALS AND METHODS: This cross-sectional study, conducted under the supervision of the Iranian Ministry of Health, presented a summary of the numbers and percentages of centers that provided infertility services in Iran, as well as the status of ART in Iran during 2011. RESULTS: A total of 52 centers reported treatment cycles and performed approximately 29000 intrauterine insemination (IUI), in addition to 35000 in vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI) cycles. CONCLUSION: Iran has considerable potential to provide IVF services for both Iranians as well as other nationalities throughout the region. This proves the need for a national center that will implement a registry system. PMID- 27695611 TI - Comparison of Quality of Life, Sexual Satisfaction and Marital Satisfaction between Fertile and Infertile Couples. AB - BACKGROUND: Fertility plays an important role in sexual and psychological function in families. Infertility can result in major emotional, social, and mental disorders, including a reduction in satisfaction with marital life and quality of life. The present study aimed to compare the quality of life and marital satisfaction and sexual satisfaction between fertile and infertile couples. MATERIALS AND METHODS: This analytical cross-sectional study was conducted on 250 couples at the Fatemiyeh Educational Research Center affiliated to Hamadan University of Medical Sciences, Hamadan, Iran, from May to August in 2014. The subjects were randomly selected from the patients referred to this center using a table of random numbers. They were then allocated into two groups of infertile group (n=125) and fertile group (n=125). The study participants completed World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire, Linda Berg's Sexual Satisfaction Scale, and Enrich Marital Satisfaction Scale. Then, the data were entered into the SPSS version16 for statistical analysis. The Chi-square and Mann-Whitney tests were also applied to compare the data between the groups. RESULTS: The results revealed no significant difference between the two groups regarding demographic and general health variables. The mean scores of sexual satisfaction were 63.67 +/- 13.13 and 46.37 +/- 7.72 in the fertile and infertile couples, respectively. Furthermore, the mean scores of marital satisfaction were also 44.03 +/- 9.36 and 36.20 +/- 4.03 in the fertile and infertile groups, respectively. Our finding demonstrated that the fertile couples obtained significantly higher mean scores of quality of life as well as lower mean scores of sexual satisfaction and marital satisfaction as compared to the infertile ones (P<0.001). CONCLUSION: According to the results, the fertile couples obtained significantly higher quality of life and lower sexual satisfaction and marital satisfaction as compared to the infertile ones. Therefore, holding consultation programs and conducting more studies are necessary for improving the quality of life and promoting sexual and marital satisfaction in infertile couples. PMID- 27695612 TI - Cord Blood Karyotyping: A Safe and Non-Invasive Method for Postnatal Testing of Assisted Reproductive Technology Children. AB - BACKGROUND: To verify the hypothesis that the incidence of chromosomal abnormalities increases in babies conceived by different assisted reproduction procedures. The availability of the umbilical cord blood encouraged us to study this hypothesis via this method. MATERIALS AND METHODS: This is a descriptive study, umbilical cord blood samples of assisted reproductive technology (ART) children were analyzed with standard cytogenetic techniques (G banding). Karyotyping was possible in 109 cases. RESULTS: The number of abnormal cases was four (3.7%), among which, three cases (2.8%) were inherited and only 1 case (0.9%) was a de novo translocation. In total, the incidence of de novo chromosomal abnormalities was in the range observed in all live births in the general population (0.7-1%). CONCLUSION: No significant difference in the incidence of chromosomal abnormality was found between ART and naturally conceived babies. To date, several studies have examined the medical and developmental outcome of ART children and still have not reached a definite conclusion. Genetic counseling is recommended as an integral part of planning of treatment strategies for couples wishing to undergo ART. PMID- 27695613 TI - Mitochondrial Genetic Variation in Iranian Infertile Men with Varicocele. AB - BACKGROUND: Several recent studies have shown that mitochondrial DNA mutations lead to major disabilities and premature death in carriers. More than 150 mutations in human mitochondrial DNA (mtDNA) genes have been associated with a wide spectrum of disorders. Varicocele, one of the causes of infertility in men wherein abnormal inflexion and distension of veins of the pampiniform plexus is observed within spermatic cord, can increase reactive oxygen species (ROS) production in semen and cause oxidative stress and sperm dysfunction in patients. Given that mitochondria are the source of ROS production in cells, the aim of this study was to scan nine mitochondrial genes (MT-COX2, MT-tRNALys , MT-ATP8, MT-ATP6, MT-COX3, MT-tRNAGly , MT-ND3, MT-tRNAArg and MT-ND4L) for mutations in infertile patients with varicocele. MATERIALS AND METHODS: In this cross sectional study, polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and DNA sequencing were used to detect and identify point mutations respectively in 9 mitochondrial genes in 72 infertile men with varicocele and 159 fertile men. In brief, the samples showing altered electrophoretic patterns of DNA in the SSCP gel were sent for DNA sequencing to identify the exact nucleotide variation. RESULTS: Ten type nucleotide variants were detected exclusively in mitochondrial DNA of infertile men. These include six novel nucleotide changes and four variants previously reported for other disorders. CONCLUSION: Mutations in mitochondrial genes may affect respiratory complexes in combination with environmental risk factors. Therefore these nucleotide variants probably lead to impaired ATP synthesis and mitochondrial function ultimately interfering with sperm motility and infertility. PMID- 27695614 TI - Expression Profile of Developmentally Important Genes in preand peri-Implantation Goat Embryos Produced In Vitro. AB - BACKGROUND: Little is understood about the regulation of gene expression during early goat embryo development. This study investigated the expression profile of 19 genes, known to be critical for early embryo development in mouse and human, at five different stages of goat in vitro embryo development (oocyte, 8-16 cell, morula, day-7 blastocyst, and day 14 blastocyst). MATERIALS AND METHODS: In this experimental study, stage-specific profiling using real time-quantitative polymerase chain reaction (RT-qPCR) revealed robust and dynamic patterns of stage specific gene activity that fall into four major clusters depending on their respective mRNA profiles. RESULTS: The gradual pattern of reduction in the maternally stored transcripts without renewal thereafter (cluster-1: Lifr1, Bmpr1, Alk4, Id3, Ctnnb, Akt, Oct4, Rex1, Erk1, Smad1 and 5) implies that their protein products are essential during early cleavages when the goat embryo is silent and reliant to the maternal legacy of mRNA. The potential importance of transcription augment at day-3 (cluster-2: Fzd, c-Myc, Cdc25a, Sox2) or day- 14 (cluster-3: Fgfr4, Nanog) suggests that they are nascent embryonic mRNAs which intimately involved in the overriding of MET or regulation of blastocyst formation, respectively. The observation of two expression peaks at both day-3 and day-14 (cluster-4: Gata4, Cdx2) would imply their potential importance during these two critical stages of preand periimplantation development. CONCLUSION: Evolutionary comparison revealed that the selected subset of genes has been rewired in goat and human/goat similarity is greater than the mouse/goat or bovine/goat similarities. The developed profiles provide a resource for comprehensive understanding of goat preimplantation development and pluripotent stem cell engineering as well. PMID- 27695615 TI - Current developments in molecular monitoring in chronic myeloid leukemia. AB - Molecular monitoring plays an essential role in the clinical management of chronic myeloid leukemia (CML) patients, and now guides clinical decision making. Quantitative reverse-transcriptase-polymerase-chain-reaction (qRT-PCR) assessment of BCR-ABL1 transcript levels has become the standard of care protocol in CML. However, further developments are required to assess leukemic burden more efficiently, monitor minimal residual disease (MRD), detect mutations that drive resistance to tyrosine kinase inhibitor (TKI) therapy and identify predictors of response to TKI therapy. Cartridge-based BCR-ABL1 quantitation, digital PCR and next generation sequencing are examples of technologies which are currently being explored, evaluated and translated into the clinic. Here we review the emerging molecular methods/technologies currently being developed to advance molecular monitoring in CML. PMID- 27695616 TI - Recent advances and novel treatment paradigms in acute lymphocytic leukemia. AB - This is an exciting time in the treatment of acute lymphoblastic leukemia (ALL) given the advances in the relapsed/refractory setting. The development of antibody treatments (including antibody drug conjugates with toxins) offers a different treatment approach compared with conventional chemotherapy regimens. Moreover, the use of bispecific T-cell-engager antibodies (BiTEs) such as blinatumomab harness the cytotoxic activity of T cells against CD19-positive lymphoblasts. Another strategy involves the use of chimeric antigen receptor (CAR) T cells. CAR T cells have demonstrated promising results in the relapsed/refractory setting. However, the use of BiTEs and CAR T cells is also associated with a distinct set of adverse reactions that must be taken into account by the treating physician. Apart from the above strategies, the use of other targeted therapies has attracted interest. Namely, the discovery of the Philadelphia (Ph)-like signature in children and young adults with ALL has led to the use of tyrosine kinase inhibitors (TKI) in these patients. The different drugs and strategies that are being tested in the relapsed/refractory ALL setting pose a unique challenge in identifying the optimum sequence of treatment and determining which approaches should be considered for frontline treatment. PMID- 27695617 TI - The potential of venetoclax (ABT-199) in chronic lymphocytic leukemia. AB - Venetoclax (VEN, ABT-199/GDC-0199) is an orally bioavailable BH3-mimetic that specifically inhibits the anti-apoptotic B-cell lymphoma/leukemia 2 (BCL2) protein. Although BCL2 overexpression is not genetically driven in chronic lymphocytic leukemia (CLL), it is nearly universal and represents a highly important and prevalent mechanism of apoptosis evasion, making it an attractive therapeutic target. This review summarizes the role of BCL2 in CLL pathogenesis, the development path targeting its inhibition prior to VEN, and the preclinical and clinical data regarding the effectiveness and safety of VEN. We further strive to contextualize VEN in the current CLL treatment landscape and discuss potential mechanisms of resistance. PMID- 27695618 TI - Treatment of multiple myeloma with the immunostimulatory SLAMF7 antibody elotuzumab. AB - Elotuzumab is a humanized monoclonal antibody targeting the extracellular domain of signaling lymphocytic activation molecule F7 (SLAMF7) highly expressed in multiple myeloma cells. Upon binding to myeloma cells, elotuzumab exerts its cytotoxic effects through antibody-dependent cellular cytotoxicity, the antibody induced selective lysis of tumor cells by activated natural killer (NK) cells. Furthermore, elotuzumab has been shown to directly induce NK-cell activation by binding to SLAMF7 expressed on NK cells and to indirectly modulate T-cell function by promoting the secretion of cytokines from NK cells. In combination with lenalidomide and low-dose dexamethasone, elotuzumab has shown remarkable effects in patients with relapsed or refractory multiple myeloma. In these patients, the risk of disease progression or death was significantly reduced by 30% on elotuzumab. Currently, elotuzumab is being evaluated in various myeloma patient populations and combination regimens. This review discusses the use of elotuzumab as an antimultiple myeloma agent and provides an update on the results of recent clinical trials evaluating the safety and efficacy of elotuzumab for the treatment of multiple myeloma. PMID- 27695620 TI - Temporal trends in the use of antidiabetic medicines: a nationwide 9-year study in older people living in New Zealand. AB - BACKGROUND: The global burden of diabetes is increasing worldwide. The aim of the study was to investigate the trends in use of antidiabetic medicines among older New Zealanders between 2005 and 2013, and to perform a separate analysis by age, sex, ethnicity, district health board domicile and socioeconomic deprivation index. METHODS: The study population included individuals' aged 65 years and older living in New Zealand (NZ) captured in the pharmaceutical collections. Repeated cross-sectional analysis of population-level dispensing data was conducted from 1 January 2005 to 31 December 2013. Linear regression model using a gamma link function was used to estimate prevalence ratios and trends between 2005 and 2013. The main outcome measure was the prevalence of antidiabetic medicines in older New Zealanders. RESULTS: The prevalence of antidiabetic medicines in older New Zealanders increased by 17.6% between 2005 and 2013. Individuals in the 70-74 age group had the highest utilization of each of the classes of antidiabetic medicines and those aged ?85 had the lowest utilization. Among the antidiabetic class of medicines, utilization of sulfonylureas was highest and alpha-glucosidase inhibitors the least. The utilization of thiazolidinediones increased over the study period. In 2013, insulin isophane and insulin glargine were the most common insulin analogues used. Insulin use was high in those aged ?85 years across the entire study period. The utilization of metformin increased gradually throughout the study period (by 43.9% in 2013 compared with 2005). CONCLUSION: This population-level study showed an increase in utilization of antidiabetic medicines in older people in NZ from 2005 to 2013; however, the increase does not seem to parallel the proportional increase in prevalence of diabetes for the study period. Improving access to newer antidiabetic medicines in line with emerging evidence should be a consideration for decision makers. PMID- 27695621 TI - Observed medical and surgical complications of prolonged barbiturate coma for refractory status epilepticus. AB - BACKGROUND: Refractory status epilepticus is often treated with third-line therapy, such as pentobarbital coma. However, its use is limited by side effects. Recognizing and preventing major and minor adverse effects of prolonged pentobarbital coma may increase good outcomes. This study retrospectively reviewed direct and indirect medical and surgical pentobarbital coma. METHODS: Retrospective chart review of all patients with refractory status epilepticus treated with pentobarbital over a 1 year period at a large tertiary care center. We collected baseline data, EEG data, and complications that were observed. RESULTS: Overall, nine patients [median age 46.4 (IQR 21.7, 75.5) years] were induced with pentobarbital coma median 11 (IQR 3, 33) days after seizure onset for a median of 9 (IQR 3.5, 45.4) days. A total of four to eight concurrent antiepileptics were tried prior to the pentobarbital coma. Phenobarbital, due to recurrence of seizures on weaning pentobarbital coma, was required in seven patients. Observed complications included peripheral neuropathy (77.8%), cerebral atrophy (33.3%), volume overload (44.4%), renal/metabolic (77.8%), gastrointestinal (66.6%), endocrine (55.6%), cardiac/hemodynamic/vascular (77.8%), respiratory (100%), and infectious (77.8%). The number of complications trended with duration of induced coma but was nonsignificant. Median ICU length of stay was 40 (IQR 28, 97.5) days. Overall, five patients were able to follow commands after a median 37 (IQR 25.5, 90) days from coma onset. There were eight patients that were discharged from hospital with three remaining in a prolonged unresponsive state. There was one patient that died prior to discharge. CONCLUSIONS: This study highlights the high morbidity in patients with refractory status epilepticus requiring pentobarbital coma. Anticipating and addressing the indirect and direct complications in prolonged pentobarbital coma may improve survival and functional outcomes in patients with refractory status epilepticus. PMID- 27695619 TI - The potential of gene therapy approaches for the treatment of hemoglobinopathies: achievements and challenges. AB - Hemoglobinopathies, including beta-thalassemia and sickle cell disease (SCD), are a heterogeneous group of commonly inherited disorders affecting the function or levels of hemoglobin. Disease phenotype can be severe with substantial morbidity and mortality. Bone marrow transplantation is curative, but limited to those patients with an appropriately matched donor. Genetic therapy, which utilizes a patient's own cells, is thus an attractive therapeutic option. Numerous therapies are currently in clinical trials or in development, including therapies utilizing gene replacement therapy using lentiviruses and the latest gene editing techniques. In addition, methods are being developed that may be able to expand gene therapies to those with poor access to medical care, potentially significantly decreasing the global burden of disease. PMID- 27695622 TI - Mirabegron in overactive bladder patients: efficacy review and update on drug safety. AB - Overactive bladder is a common condition, which significantly affects people's quality of life. The use of anticholinergic medication has been the mainstay of managing overactive bladder when conservative measures are not enough. Many patients stop anticholinergic medication because of the side effects and more recently the concerns about the effect of an anticholinergic burden and the development of dementia have been studied. Activation of beta3 adrenoceptors has been shown to relax the detrusor muscle and subsequently lead to the development of the first beta3 adrenoceptor agonist. Mirabegron is the first drug in this class to be approved for the use in overactive bladder. It has been extensively studied in phase II and III trials and has significant improvement in key overactive bladder parameters when compared with placebo. The incidence of side effects such as constipation, hypertension and tachycardia were comparable to anticholinergic medication but there was significantly less dry mouth incidence in the mirabegron groups. Mirabegron has been shown to be used safely in combination with solifenacin and tamsulosin. Head-to-head studies comparing efficacy and safety of mirabegron with anticholinergic medication would further help in the management strategy for overactive bladder. PMID- 27695623 TI - Anticholinergic medication use and dementia: latest evidence and clinical implications. AB - Use of medications with anticholinergic activity is widespread in older adults. Several studies have highlighted that anticholinergic use may be associated with an increased risk of dementia. The objective of this narrative review is to describe and evaluate studies of anticholinergic medication use and dementia and provide practical suggestions for avoiding use of these medications in older adults. A comprehensive review of the literature, citations from recent reviews and the author's personal files was conducted. Four studies were found that evaluated anticholinergic use and dementia as the primary outcome. Three studies focused on overall anticholinergic medication use and reported a statistically significantly increased risk of Alzheimer's disease or dementia. In one study, dementia risk was primarily found with higher cumulative doses; people using anticholinergic medications at the minimum effective dose recommended for older adults for at least 3 years were at highest risk. In contrast, a study conducted in nursing-home residents with depression did not find that paroxetine [a highly anticholinergic selective serotonin reuptake inhibitor antidepressant, (SSRI)] increased risk for dementia compared with other SSRIs (without anticholinergic activity). Further study is needed to understand the mechanism by which anticholinergic medications may increase risk. In conclusion, there is evidence from three observational studies suggesting that anticholinergic medications may increase dementia risk. Given this potential risk and the myriad of other well known adverse effects (i.e. constipation, blurred vision, urinary retention, and delirium) associated with anticholinergic medications, it is prudent for prescribers and older adults to minimize use of these medications and consider alternatives when possible.

PMID- 27695625 TI - Vascular Endothelial Growth Factor Increases Endothelial Nitric Oxide Synthase Transcription In Huvec Cells. AB - Although it is known that VEGF increases eNOS protein, the mechanisms responsible remain unclear. To determine if VEGF alters eNOS transcription, human umbilical vein endothelial cells were transfected with reporters under the control of the eNOS promoter and stimulated with VEGF165. VEGF significantly increased eNOS-mRNA after 2 hours exposure. VEGF significantly increased eNOS reporter activity as early as one hour (268+/-32%), but this increase returned to baseline after 6 hours. Using deletion constructs, the VEGF response region was initially localized to within the -722/-494 region. GMSA indicated that VEGF increased DNA binding to both a cAMP-like and AP1-like response elements. Site-specific mutations and heterologous constructs indicated that the site centered at AP1 like site was both necessary and sufficient to meditate VEGF transcriptional activation. These results indicate that VEGF rapidly activates eNOS transcription prior to a rise eNOS-mRNA, an effect mediated by a cis-trans interaction localized to an AP1-like site within the eNOS promoter. PMID- 27695626 TI - Thermal time constant: optimising the skin temperature predictive modelling in lower limb prostheses using Gaussian processes. AB - Elevated skin temperature at the body/device interface of lower-limb prostheses is one of the major factors that affect tissue health. The heat dissipation in prosthetic sockets is greatly influenced by the thermal conductive properties of the hard socket and liner material employed. However, monitoring of the interface temperature at skin level in lower-limb prosthesis is notoriously complicated. This is due to the flexible nature of the interface liners used which requires consistent positioning of sensors during donning and doffing. Predicting the residual limb temperature by monitoring the temperature between socket and liner rather than skin and liner could be an important step in alleviating complaints on increased temperature and perspiration in prosthetic sockets. To predict the residual limb temperature, a machine learning algorithm - Gaussian processes is employed, which utilizes the thermal time constant values of commonly used socket and liner materials. This Letter highlights the relevance of thermal time constant of prosthetic materials in Gaussian processes technique which would be useful in addressing the challenge of non-invasively monitoring the residual limb skin temperature. With the introduction of thermal time constant, the model can be optimised and generalised for a given prosthetic setup, thereby making the predictions more reliable.

PMID- 27695628 TI - Effects of Acupuncture Stimulation on the Radial artery's Pressure Pulse Wave in Healthy Young Participants: Protocol for a prospective, single-Arm, Exploratory, Clinical Study. AB - INTRODUCTION: This study aims to investigate the effects of acupuncture stimulation on the radial artery's pressure pulse wave, along with various hemodynamic parameters, and to explore the possible underlying mechanism of pulse diagnosis in healthy participants in their twenties. METHODS AND ANALYSIS: This study is a prospective, single-arm, exploratory clinical study. A total of 25 healthy participants, without regard to gender, in their twenties will be recruited by physicians. Written informed consent will be obtained from all participants. The participants will receive acupuncture once at ST36 on both sides. The radial arterial pulse waves will be measured on the left arm of the subjects by using an applicable pulse tonometric device (KIOM-PAS). On the right arm (appearing twice), electrocardiogram (ECG), photoplethysmogram (PPG), respiration and cardiac output (CO) signals, will be measured using a physiological data acquisition system (Biopac module), while the velocity of blood flow, and the diameter and the depth of the blood vessel will be measured using an ultrasonogram machine on the right arm (appearing twice). All measurements will be conducted before, during, and after acupuncture. The primary outcome will be the spectral energy at high frequencies above 10 Hz (SE10-30Hz) calculated from the KIOM-PAS device signal. Secondary outcomes will be various variables obtained from the KIOM-PAS device, ECG, PPG, impedance cardiography modules, and an ultrasonogram machine. DISCUSSION: The results of this trial will provide information regarding the physiological and the hemodynamic mechanisms underlying acupuncture stimulation and clinical evidence for the influence of acupuncture on the pressure pulse wave in the radial artery. ETHICS AND DISSEMINATION: This study was approved by the Institutional Review Board (IRB) of Kyung Hee University's Oriental Medical Center, Seoul, Korea (KOMCIRB-150818-HR 030). The study findings will be published in peer-reviewed journals and presented at national and international conferences. TRIAL REGISTRATION NUMBER: This trial was registered with the Clinical Research Information Service (CRIS) at the Korea National Institute of Health (NIH), Republic of Korea (KCT0001663), which is a registry in the World Health Organization's (WHO's) Registry Network. PMID- 27695629 TI - Nonlinear Conte-Zbilut-Federici (CZF) Method of Computing LF/HF Ratio: A More Reliable Index of Changes in Heart Rate Variability. AB - OBJECTIVES: Acupuncture treatments are safe and effective for a wide variety of diseases involving autonomic dysregulation. Heart rate variability (HRV) is a noninvasive method for assessing sympathovagal balance. The low frequency/high frequency (LF/HF) spectral power ratio is an index of sympathovagal influence on heart rate and of cardiovascular health. This study tests the hypothesis that from rest to 30% to 50% of peak oxygen consumption, the nonlinear Conte-Zbilut Federici (CZF) method of computing the LF/HF ratio is a more reliable index of changes in the HRV than linear methods are. METHODS: The subjects of this study were 10 healthy young adults. Electrocardiogram RR intervals were measured during 6-minute periods of rest and aerobic exercise on a cycle ergometer at 30% and 50% of peak oxygen consumption (VO2peak). RESULTS: The frequency domain CZF computations of the LF/HF ratio and the time domain computations of the standard deviation of normal-to-normal intervals (SDNN) decreased sequentially from rest to 30% VO2peak (P < 0.001) to 50% VO2peak (P < 0.05). The SDNN and the CZF computations of the LF/HF ratio were positively correlated (Pearson's r = 0.75, P < 0.001). fast Fourier transform (FFT), autoregressive (AR) and Lomb periodogram computations of the LF/HF ratio increased only from rest to 50% VO2peak. CONCLUSION: Computations of the LF/HF ratio by using the nonlinear CZF method appear to be more sensitive to changes in physical activity than computations of the LF/HF ratio by using linear methods. Future studies should determine whether the CZF computation of the LF/HF ratio improves evaluations of pharmacopuncture and other treatment modalities.

AB - OBJECTIVES: Ginseng Rh2+ is enzyme-treated ginseng extract containing high amounts of converted ginsenosides, such as compound k, Rh2, Rg3, which have potent anticancer activity. We conducted general and genetic toxicity tests to evaluate the safety of ginseng Rh2+. METHODS: An acute oral toxicity test was performed at a high-level dose of 4,000 mg/kg/day in Sprague-Dawley (SD) rats. A 14-day range-finding study was also conducted to set dose levels for the 90-day study. A subchronic 90-day toxicity study was performed at dose levels of 1,000 and 2,000 mg/kg/day to investigate the no-observed-adverse-effect level (NOAEL) of ginseng Rh2+ and target organs. To identify the mutagenic potential of ginseng Rh2+, we conducted a bacterial reverse mutation test (Ames test) using amino-acid requiring strains of Salmonella typhimurium and Escherichia coli (E. coli), a chromosome aberration test with Chinese hamster lung (CHL) cells, and an in vivo micronucleus test using ICR mice bone marrow as recommended by the Korean Ministry of Food and Drug Safety. RESULTS: According to the results of the acute oral toxicity study, the approximate lethal dose (ALD) of ginseng Rh2+ was estimated to be higher than 4,000 mg/kg. For the 90-day study, no toxicological effect of ginseng Rh2+ was observed in body-weight changes, food consumption, clinical signs, organ weights, histopathology, ophthalmology, and clinical pathology. The NOAEL of ginseng Rh2+ was established to be 2,000 mg/kg/day, and no target organ was found in this test. In addition, no evidence of mutagenicity was found either on the in vitro genotoxicity tests, including the Ames test and the chromosome aberration test, or on the in vivo in mice bone marrow micronucleus test. CONCLUSION: On the basis of our findings, ginseng Rh2+ is a non-toxic material with no genotoxicity. We expect that ginseng Rh2+ may be used as a novel adjuvant anticancer agent that is safe for long-term administration. PMID- 27695631 TI - Bee Venom (Apis Mellifera) an Effective Potential Alternative to Gentamicin for Specific Bacteria Strains: Bee Venom an Effective Potential for Bacteria. AB - OBJECTIVES: Mellitine, a major component of bee venom (BV, Apis mellifera), is more active against gram positive than gram negative bacteria. Moreover, BV has been reported to have multiple effects, including antibacterial, antivirus, and anti-inflammation effects, in various types of cells. In addition, wasp venom has been reported to have antibacterial properties. The aim of this study was to evaluate the antibacterial activity of BV against selected gram positive and gram negative bacterial strains of medical importance. METHODS: This investigation was set up to evaluate the antibacterial activity of BV against six grams positive and gram negative bacteria, including Staphylococcus aureus (S. aureus), Salmonella typhimurium, Escherichia coli (E. coli) O157:H7, Pseudomonas aeruginosa, Burkholderia mallei and Burkholderia pseudomallei. Three concentrations of crude BV and standard antibiotic (gentamicin) disks as positive controls were tested by using the disc diffusion method. RESULTS: BV was found to have a significant antibacterial effect against E. coli, S. aureus, and Salmonella typhyimurium in all three concentrations tested. However, BV had no noticeable effect on other tested bacteria for any of the three doses tested. CONCLUSION: The results of the current study indicate that BV inhibits the growth and survival of bacterial strains and that BV can be used as a complementary antimicrobial agent against pathogenic bacteria. BV lacked the effective proteins necessary for it to exhibit antibacterial activity for some specific strains while being very effective against other specific strains. Thus, one may conclude, that Apis mellifera venom may have a specific mechanism that allows it to have an antibacterial effect on certain susceptible bacteria, but that mechanism is not well understood. PMID- 27695632 TI - Assessment of the Toxicity and the Stability of Saeng Mak San by Using Repeated Intravenous Injections in Sprague-Dawley Rats. AB - OBJECTIVES: This study used repeated intravenous injections of Saeng Maek San (SMS) injection in Sprague-Dawley (SD) rats to assess the toxicity and the stability of SMS. METHODS: Six-week-old male and female SD rats reared by Orient bio Inc were chosen for this pilot study. They were randomly split into four groups: Group 1 (G1), the control group (0.3 mL of normal saline solution/day/animal), and Groups 2, 3 and 4 (G2, G3 and G4), the experimental groups (0.1, 0.2 and 0.3 mL/day/animal of SMS), respectively. Each animal received an intravenous injection of SMS once a day for four weeks. Clinical signs, body weight changes, and food consumption were monitored during the observation period, and urinalysis and hematology were conducted after four weeks of SMS or saline administration. RESULTS: No deaths occurred in any of the four groups during the observation period. Compared to the control group, male and female rats in groups 3 and 4 (0.2 and 0.3 mL/animal/day) showed hemoglobinuria, but the low-dosage group (G2, 0.1 mL/animal/day) showed no significant changes in the clinical signs test. No significant changes due to SMS were observed in the experimental groups regarding body weight changes, food consumption urinalysis, or hematology. CONCLUSION: During this study, no mortalities were observed in any of the experimental groups and no hemoglobinuria was observed in the low dosage group (0.1 mL/animal/day) while it was intermittently observed in groups 3 and 4 (0.2 and 0.3 mL/animal/day). Thus, we suggest that the no-observed adverse-effect level (NOAEL) is 0.1 mL/animal/day in male and female SD rats. PMID- 27695633 TI - Agarwood Inhibits Histamine Release from Rat Mast Cells and Reduces Scratching Behavior in Mice: Effect of Agarwood on Histamine Release and Scratching Behavior. AB - OBJECTIVES: This study was conducted to clarify the effects of agarwood on histamine release from mast cells in rats and on the scratching behaviors in mice. METHODS: Histamine release from rat mast cells induced by compound 48/80 or concanavalin A (Con A) and compound 48/80-induced scratching behavior in mice were examined to investigate the effects of agarwood. The hyaluronidase activity and the 3',5'-cyclic adenosine monophosphate (cAMP) levels in mast cells were examined to investigate the mechanisms for the inhibition of histamine release. The correlation between the inhibitory effects of agarwood on histamine release and the content of its typical ingredients, a 2-(2-phenylethyl)chromone derivatives, was analyzed using thin-layer chromatography. RESULTS: Agarwood showed an inhibitory effect on mast-cell histamine release induced by compound 48/80 or Con A without any effect on hyaluronidase activity; this effect involves an increase in the cAMP levels in mast cells. Oral administration of agarwood showed an inhibitory effect on compound 48/80-induced scratching behavior in mice. The inhibitory effects of agarwood on histamine release were quite different, depending on the area where the agarwood was produced, its quality, and its market price. No correlation was found between the inhibitory effects of agarwood on histamine release and the typical ingredients of agarwood, which are 2-(2-phenylethyl)chromone derivatives. CONCLUSION: These results show that agarwood inhibits histamine release from mast cells partially through an increase in the cAMP levels in cells. We suggest that some active ingredients of agarwood must be effective on oral intake and that agarwood can be used to treat patients with a number of conditions, including urticaria, atopic dermatitis, and bronchial asthma, in which an increase in histamine release occurs. Differences in the pharmacological effects of this crude drug among markets may provide important information for the quality control of this herbal medicine. PMID- 27695634 TI - Phenol-Rich Compounds Sweet Gel: A Statistically More Effective Antibiotic than Cloxacillin Against Pseudomonas Aeruginosa. AB - OBJECTIVES: The purpose of this study was to obtain a natural antibiotic from Phenol-rich compounds; for the dressing and the treatment of chronic wounds. METHODS: The Phenol-rich compound sweet gel was prepared by blending four natural herbal extracts, Acacia catechu (L.F.), Momia (Shilajit), Castanea sativa, and Ephedra sinica stapf, with combination of a sweet gel medium, including honey, maple saps, Phoenix dactylifera L. (date), pomegranate extract and Azadirachta indica gum as a stabilizer. The combinations were screened by using a well diffusion assay with cloxacillin as a control. Pseudomonas spp. was tested with our novel antimicrobial compound. The zones of inhibition in agar culture were measured for each individual component and for the compound, and the results were compared with those of the control group which had been treated with cloxacillin. Data were expressed as means +/- standard deviations. Quantitative analyses were performed using the paired t-test. RESULTS: The antibiotic effect of the Phenol rich compound sweet gel was statistically shown to be more significant than that of cloxacillin against Pseudomonas aeruginosa (P < 0.05). CONCLUSION: Our novel approach to fighting the antibiotic resistance of Pseudomonas proved to be successful. The Phenol-rich compound sweet gel was found to be suitable for use as an alternative medicine and bioactive dressing material, for the treatment of patients with various types of wounds, including burns, venous leg ulcers, ulcers of various etiologies, leg ulcers on the feet of diabetic, unhealed graft sampling sites, abscesses, boils, surgical wounds, necrotic process, post operative and neonatal wound infection, and should be considered as an alternative to the usual methods of cure. PMID- 27695635 TI - Toxicity and Safety Profiles of Methanolic Extract of Pistacia integerrima J. L. Stewart ex Brandis (PI) for Wistar Rats. AB - OBJECTIVES: The goals of this research were to evaluate acute (single-dose) and sub-acute (repeated-dose) toxicity profiles of methanolic extract of Pistacia integerrima J. L. Stewart ex Brandis (PI) for Wistar rats and to assess the safety profile of PI by observing physiological changes, mortality, changes in body weight, the histopathology of body organs, the hematology and the biochemistry of the animals. METHODS: The toxicity profile of PI was evaluated using Wistar rats of both sexes. Animals were divided into four groups: Group 1; control group (normal saline), Group 2; PI-1 (250 mg/kg), Group 3; PI-2 (500 mg/kg), Group 4; PL-3 (1,000 mg/kg). An acute-toxicity study in which animals received a single dose of PI extract (2,000 mg/ kg) and were then observed for 14 days for changes in skin, fur, eye color, mucous membrane secretions and excretions, gait, posture, and tonic or clonic movements was performed according to guideline 425 of the Organization of Economic and Corporation Development (OECD). In the repeated-dose toxicity study (OECD - 407) animals received a daily dose of PI extract for 28 days (4 weeks). The parameters observed in this study include body weight, hematology and biochemistry of the animals. RESULTS: In the acute toxicity study, no mortalities or changes in behavior were noted in the animals. The repeated-dose toxicity study was also devoid of any toxicity in the animals during the 28 days of testing with PI extract. The extract did not alter- the body weight, hematology or biochemistry of the animals. The methanolic extract of PI was to be found safe to the no-observed-adverse-effect-level (NOAEL) for the single- dose and repeated-dose toxicity tests in rats. CONCLUSION: The methanolic extract of PI was devoid of toxicity; hence, it can be used for various ayurvedic preparations and treatments of diseases. PMID- 27695636 TI - Combination Therapy of Gefitinib and Korean Herbal Medicines Could be a Beneficial Option for Patients with Non-Small-Cell Lung Cancer. AB - ABSTRACT: ABSTRACT: Lung cancer has a high mortality rate and is often diagnosed at the metastatic stage. Gefitinib is a targeted molecular therapeutic drug used to treat patients with non-small-cell lung cancer (NSCLC). Korean herbal medicines may also have therapeutic efficacy against lung cancer, reduce the side effects associated with chemotherapy, and improve patient quality of life (QOL). This case report describes the effects of a Korean herbal medicine regimen combined with gefitinib in a patient with NSCLC and bone metastasis. The Korean herbal medicine regimen included woohwanggeosa-dan, hwanggibujeong-dan and geonchilgyebok-jeong. The computed tomography (CT) findings showed that following combination treatment, the size of the tumor was markedly decreased without serious adverse events. Moreover, the Eastern Cooperative Oncology Group (ECOG) performance status was improved and cancer-related pain was decreased. These results suggest that a combination of Korean herbal medicines and gefitinib may be an effective therapeutic option for patients with advanced NSCLC and bone metastasis. Further studies are needed to examine the mechanism and the clinical efficacy of Korean herbal medicines against NSCLC.

AB - Information of paddy rice distribution is essential for food production and methane emission calculation. Phenology-based algorithms have been utilized in the mapping of paddy rice fields by identifying the unique flooding and seedling transplanting phases using multi-temporal moderate resolution (500 m to 1 km) images. In this study, we developed simple algorithms to identify paddy rice at a fine resolution at the regional scale using multi-temporal Landsat imagery. Sixteen Landsat images from 2010-2012 were used to generate the 30 m paddy rice map in the Sanjiang Plain, northeast China-one of the major paddy rice cultivation regions in China. Three vegetation indices, Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), and Land Surface Water Index (LSWI), were used to identify rice fields during the flooding/transplanting and ripening phases. The user and producer accuracies of paddy rice on the resultant Landsat-based paddy rice map were 90% and 94%, respectively. The Landsat-based paddy rice map was an improvement over the paddy rice layer on the National Land Cover Dataset, which was generated through visual interpretation and digitalization on the fine-resolution images. The agricultural census data substantially underreported paddy rice area, raising serious concern about its use for studies on food security. PMID- 27695639 TI - Caries Experience and Periodontal Status during Pregnancy in a Group of Pregnant Women with HIV+ Infections from Puerto Rico. AB - OBJECTIVES: The aim of this study was to determine the caries rate and periodontal status in a sample of pregnant women with HIV+ infections from Puerto Rico. METHODS: A pilot study was conducted on a cross sectional convenience sample of 25 pregnant women with HIV+ infections from Puerto Rico who visit the CEMI clinic (Centro de Estudios Materno Infantil) at the University of Puerto Rico. The women subjects were evaluated for caries, DMFT (D: Decay tooth; M: Missing tooth due to caries; F: Filled tooth) index, oral lesions associated with HIV+/AIDS and periodontal disease parameters, with a Florida probe by a calibrated dentist on periodontal indexes such as as bleeding on probing, CEJ (cemento-enamel junction) and pocket depth. Periodontal disease was classified as having 4 sites with pocket depth greater than 4 mm and caries were identified following the Radike criteria. Data was statistically analyzed using the SSPS Program (Statistical Software Program for Social Sciences) and descriptive statistics were calculated. RESULTS: Mean DT (decayed teeth), MT (missing teeth due to caries), FT (filled teeth) and DMFT (decay, missing and filled teeth) were 4.8, 1.86, 5.3 and 12, respectively; mean sites of bleeding on probing=12.06; mean sites with pocket depth>4 mm=6.95 and mean sites with loss of attachment greater than 4 mm=7.66. [Almost 50% of the patients had generalized chronic periodontitis. A 72% prevalence of periodontal disease was found. No oral lesions related to HIV+/AIDS were reported. CD4 and viral load was statistically associated with bleeding on probing and severe signs of periodontal disease. CONCLUSIONS: High levels of dental disease were found in pregnant women with HIV+/AIDS infections from Puerto Rico, and these women were in need of substantial dental services. PMID- 27695638 TI - Frontal Metabolite Concentration Deficits in Opiate Dependence Relate to Substance Use, Cognition, and Self-Regulation. AB - OBJECTIVE: Proton magnetic resonance spectroscopy (1H MRS) in opiate dependence showed abnormalities in neuronal viability and glutamate concentration in the anterior cingulate cortex (ACC). Metabolite levels in dorsolateral prefrontal cortex (DLPFC) or orbitofrontal cortex (OFC) and their neuropsychological correlates have not been investigated in opiate dependence. METHODS: Single volume proton MRS at 4 Tesla and neuropsychological testing were conducted in 21 opiate-dependent individuals (OD) on buprenorphine maintenance therapy. Results were compared to 28 controls (CON) and 35 alcohol-dependent individuals (ALC), commonly investigated treatment-seekers providing context for OD evaluation. Metabolite concentrations were measured from ACC, DLPFC, OFC and parieto occipital cortical (POC) regions. RESULTS: Compared to CON, OD had lower concentrations of N-acetylaspartate (NAA), glutamate (Glu), creatine +phosphocreatine (Cr) and myo-Inositol (mI) in the DLPFC and lower NAA, Cr, and mI in the ACC. OD, ALC, and CON were equivalent on metabolite levels in the POC and gamma-aminobutyric acid (GABA) concentration did not differ between groups in any region. In OD, prefrontal metabolite deficits in ACC Glu as well as DLPFC NAA and choline containing metabolites (Cho) correlated with poorer working memory, executive and visuospatial functioning; metabolite deficits in DLPFC Glu and ACC GABA and Cr correlated with substance use measures. In the OFC of OD, Glu and choline-containing metabolites were elevated and lower Cr concentration related to higher nonplanning impulsivity. Compared to 3 week abstinent ALC, OD had significant DLPFC metabolite deficits. CONCLUSION: The anterior frontal metabolite profile of OD differed significantly from that of CON and ALC. The frontal lobe metabolite abnormalities in OD and their neuropsychological correlates may play a role in treatment outcome and could be explored as specific targets for improved OD treatment. PMID- 27695640 TI - Three common misuses of P values. AB - "Significance" has a specific meaning in science, especially in statistics. The p value as a measure of statistical significance (evidence against a null hypothesis) has long been used in statistical inference and has served as a key player in science and research. Despite its clear mathematical definition and original purpose, and being just one of the many statistical measures/criteria, its role has been over-emphasized along with hypothesis testing. Observing and reflecting on this practice, some journals have attempted to ban reporting of p values, and the American Statistical Association (for the first time in its 177 year old history) released a statement on p-values in 2016. In this article, we intend to review the correct definition of the p-value as well as its common misuses, in the hope that our article is useful to clinicians and researchers.

PMID- 27695641 TI - Cell Intrinsic Factors Modulate the Effects of IFNgamma on the Development of Chlamydia trachomatis. AB - Chlamydia trachomatis is an obligate intracellular bacterial pathogen that cannot synthesize several amino acids, including tryptophan. Rather, C. trachomatis acquires these essential metabolites from its human host cell. Chlamydial dependence on host-provided tryptophan underlies a major host defense mechanism against the bacterium; namely, the induction of the host tryptophan-catabolizing enzyme, indoleamine 2,3- dioxygenase (IDO1) by interferon gamma (IFNgamma), which leads to eradication of C. trachomatis by tryptophan starvation. For this reason, IFNgamma is proposed to be the major host protective cytokine against genital C. trachomatis infections. The protective effect of IFNgamma against C. trachomatis can be recapitulated in vitro using epithelial cell-lines such as the cervical carcinoma derived cell-line Hela, the Hela subclone HEp-2, and the cervical carcinoma derived cell-line ME180. Addition of IFNgamma to these cells infected with C. trachomatis results in a strong bactericidal or bacteriostatic effect dependent on the concentration of IFNgamma administered. Unlike Hela, HEp-2, and ME180, there are other human epithelial, or epithelial-like cell-lines where administration of IFNgamma does not affect chlamydial replication, although they express the IFNgamma receptor (IFNGR). In this report, we have characterized the mechanisms that underlie this dichotomy using the cell-lines C33A and 293. Akin to Hela, C33A is derived from a human cervical carcinoma, while 293 cells were produced by transfection of adenovirus type 5 DNA into embryonic kidney cells. We demonstrate that although IFNGR is expressed at high levels in C33A cells, its ligation by IFNgamma does not result in STAT1 phosphorylation, an essential step for activation of the IDO1 promoter. Our results indicate that although the IFNgamma-dependent signaling cascade is intact in 293 cells; the IDO1 promoter is not activated in these cells because it is epigenetically silenced, most likely by DNA methylation. Because polymorphisms in IFNgamma, IFNGR, and the IDO1 promoter are known to affect other human infections or diseased states, our results indicate that the effect of allelic differences in these genes and the pathways they activate should be evaluated for their effect on C. trachomatis pathology. PMID- 27695643 TI - Francisella tularensis - Immune Cell Activator, Suppressor, or Stealthy Evader: The Evolving View from the Petri Dish. AB - One of the hallmarks of pulmonary tularemia, which results from inhalation of Francisella tularensis - a significant bioterrorism concern, is the lack of an acute TH1-biased inflammatory response in the early phase of disease (days 1-3) despite significant bacterial loads. In an effort to understand this apparent hypo-responsiveness, many laboratories have utilized in vitro cell-based models as tools to probe the nature and consequences of host cell interactions with F. tularensis. The first uses of this model suggested that mammalian host cells recognize this bacterium principally through TLR2 to evoke a robust, classical TH1-biased cytokine response including TNF, IL-6, IL-1beta, and IFN-gamma. Others used this model in concert with a variety of non-genetic perturbations of the bacterial-host cell interaction and suggested that F. tularensis actively suppressed the cellular response. Consistent with this notion, others engaged this model to assess isogenic mutants and, in many cases, found the mutant bacteria to be more pro-inflammatory than their WT counter-parts. Frequently, these observations were interpreted as evidence for the immunosuppressive function of the gene of interest. However, recently appreciated roles of the health of the bacterium and the impact of host factors have refined this model to suggest a "stealthy" mode of bacterial-host cell interaction (rather than one involving active suppression) consistent with the observations during early phase disease. PMID- 27695644 TI - Neonatal Enterovirus Infection: Case Series of Clinical Sepsis and Positive Cerebrospinal Fluid Polymerase Chain Reaction Test with Myocarditis and Cerebral White Matter Injury Complications. AB - Objective We describe five neonates with enteroviral (EV) infection to demonstrate central nervous system (CNS) and cardiac complications and report successful treatment of myocarditis with immunoglobulin intravenous (IVIG) in two. Study Design Case series identified during three enteroviral seasons in one neonatal intensive care unit (NICU) by cerebral spinal fluid (CSF) reverse transcriptase polymerase chain reaction (PCR) testing for EV in neonates suspected to have sepsis, but with sterile bacterial cultures. Results Cases were identified in each of three sequential years in a NICU with 800 to 900 admissions/year. Two cases were likely acquired perinatally; all were symptomatic with lethargy and poor feeding by age 5 to 10 days. All had signs of sepsis and/or meningitis; one progressed to periventricular leukomalacia and encephalomalacia. Two recovered from myocarditis after treatment that included IVIG 3 to 5 g/kg. Conclusion Neonates who appear septic without bacterial etiology may have EV CNS infections that can be diagnosed rapidly by CSF PCR testing. Cases may be underdiagnosed in the early neonatal period if specific testing is not performed. Neonates with EV infection should be investigated for evidence of periventricular leukomalacia, screened for myocarditis, and considered for IVIG treatment. PMID- 27695645 TI - Targeting Glioma with a Dual Mode Optical and Paramagnetic Nanoprobe across the Blood-brain Tumor Barrier. AB - In brain tumors, delivering nanoparticles across the blood-tumor barrier presents major hurdles. A clinically relevant MRI contrast agent, GdDOTA and a near infrared (NIR) fluorescent dye, DL680 were conjugated to a G5 PAMAM dendrimer, thus producing a dual-mode MRI and NIR imaging agent. Systemic delivery of the subsequent nano-sized agent demonstrated glioma-specific accumulation, probably due to the enhanced permeability and retention effect. In vivo MRI detected the agent in glioma tissue, but not in normal contralateral tissue; this observation was validated with in vivo and ex vivo fluorescence imaging. A biodistribution study showed the agent to have accumulated in the glioma tumor and the liver, the latter being the excretion path for a G5 dendrimer-based agent. PMID- 27695646 TI - The Impact of Strong for Life on the Physical Functioning and Health of Older Adults Receiving Home and Community-Based Services. AB - BACKGROUND/OBJECTIVES: To test the effects of Strong for Life (SFL) on the physical performance and self-rated health of older adults receiving Home and Community-Based Services (HCBS). DESIGN: Randomized, two-group trial with pre post measures. SETTING: In-home exercise program. PARTICIPANTS: Clients aged 65 95 (n=42) and their Home Care Aide (HCA) (n=32) were randomly assigned to a usual care and SFL intervention or usual care control group. INTERVENTION: Clients were instructed in SFL by their HCA and completed SFL 3 times per week for 12-weeks. MEASUREMENTS: Outcomes included grip and quadriceps strength, Timed Up and Go, gait speed, Self-Efficacy for Exercise, pain, and PROMIS-global health measured at baseline and immediately following the intervention. Clients completed opened ended survey items on SFL program evaluation. RESULTS: Effect sizes were moderate for grip strength (d= .38), pain (d= .34), and PROMIS-global health (d= .27). Small effect sizes were found for all other measures. Median quadriceps and TUG scores differentially improved among intervention participants versus controls. No adverse health events and high program satisfaction were reported. Frailty prevalence in the control group increased between baseline and post-test while frailty prevalence in the intervention group decreased during the same time period. CONCLUSION: Strong for Life has the potential to improve the strength, mobility, health, and frailty of older adults receiving HCBS. This study provides initial evidence of the impact of SFL for older adults receiving HCBS, as well as the safety of the intervention evidenced by the lack of reported adverse events. PMID- 27695647 TI - Chemotherapy for Elderly Ovarian Cancer Patients. AB - OBJECTIVE: Ovarian cancer is the most lethal cancer involving the female pelvic reproductive system. Its incidence increases with age and with an aging population, its prevalence should also increase. The goal of our retrospective study is to report our experience in treating women over 65 years of age, with a diagnosis of primary ovarian cancer, using standard intravenous chemotherapy. METHODS: The medical records of 78 patients>65 years of age diagnosed with primary ovarian cancer at the Yale Cancer Center between 1996-2006 were retrospectively reviewed and included in our analysis. Patients had stage I-IV disease (stage I n=5, stage II n=8, stage III n=36, stage IV n=25, unknown n=4). RESULTS: Sixty-three of 78 women (80.8%) completed the prescribed regimen; and 62 women did not require a dose reduction or chemotherapy discontinuation. The most common reason for a dose reduction or treatment discontinuation was fatigue (6.4%), neutropenia (2.6%), patient preference (2.6%), and multiple co morbidities (2.6%). The most commonly used regimen was paclitaxel 175mg/m2 and carboplatin AUC 5. The hazard ratio for PFS and OS for patients who had dose reduction/discontinuation versus those who completed the prescribed dose was 1.3 (95% CI 0.51-3.26) and 0.63 (95% CI 0.17-2.33), respectively. CONCLUSIONS: Our findings illustrate that elderly women are able to tolerate standard chemotherapy with relatively few significant adverse effects. While different treatment modalities in ovarian cancer are continually being evaluated, additional prospective studies are required to better understand the tolerability and efficacy of such treatment in the elderly population. PMID- 27695648 TI - Shape Effect of Glyco-Nanoparticles on Macrophage Cellular Uptake and Immune Response. AB - The shells of various poly(dl-lactide)-b-poly(acrylic acid) (PDLLA-b-PAA) spherical micelles and poly(l-lactide)-b-poly(acrylic acid) (PLLA-b-PAA) cylindrical micelles were functionalized with mannose to yield glyco nanoparticles (GNPs) with different shapes and dimensions. All of these GNPs were shown to have good biocompatibility (up to 1 mg/mL). Cellular uptake experiments using RAW 264.7 have shown that the spherical GNPs were internalized to a much greater extent than the cylindrical GNPs and such a phenomenon was attributed to their different endocytosis pathways. It was demonstrated that spherical GNPs were internalized based on clathrin- and caveolin-mediated endocytosis while cylindrical GNPs mainly depended on clathrin-mediated endocytosis. We also found that longer cylindrical GNPs (Ln * Wn = 215 * 47 nm) can induce an inflammatory response (specifically interleukin 6) more efficiently than shorter cylindrical GNPs (Ln * Wn = 99 * 50 nm) and spherical GNPs (Dn = 46 nm). PMID- 27695649 TI - Marriage shrines and worms impacting our understanding of mammalian fertilization. AB - Genetic approaches in C. elegans are complementing the biochemical and antibody based strategies traditionally used to study the molecular underpinnings of fertilization in other organisms. A pair of worm studies, one based on forward genetics and one based on reverse genetics, converge on the sperm immunoglobulin superfamily molecule SPE-45. Loss of spe-45 function leads to the production of sperm that cannot fertilize wild-type eggs. This is a strikingly similar phenotype as those seen in mice lacking the immunoglobulin superfamily protein Izumo1. This work sets the stage for leveraging the power of the C. elegans model system to learn more about Izumo-like molecular function but also for the discovery of additional deeply conserved components of fertility pathways. PMID- 27695651 TI - New insights into old worm proteomes. AB - Aging is accompanied by large-scale changes in the proteome, which could have important consequences for cellular and organismal physiology. In this commentary, we review recent studies characterizing the aging proteome in C. elegans. We assess the evidence that the rates of protein synthesis, folding, and degradation change with age in C. elegans, and evaluate whether changes in these pathways limit normal lifespan. We also discuss large-scale studies measuring changes in the proteome with age that suggest that a failure to excrete reproductive proteins in post-reproductive animals plays a role in changing protein levels with age. PMID- 27695650 TI - Globin-based redox signaling. AB - In recent years, moderate levels of reactive oxygen species (ROS) have become recognized as signaling cues that participate at all levels of cellular organization. Globins, with their redox-active heme iron and ubiquitous presence, seem ideally suited to participate in ROS metabolism. Here we comment on our recent findings that show the participation of a globin, GLB-12, in a redox signaling pathway in Caenorhabditis elegans. We found that GLB-12 produces superoxide, a type of ROS, after which this is converted to what appears to be a hydrogen peroxide gradient over the plasma membrane by the activity of intracellular and extracellular superoxide dismutases. In the first part, we discuss in more detail the different regulatory mechanisms that increase the effectiveness of this redox signal. In the second part, we comment on how specific structural and biochemical properties allow this globin to perform redox reactions. Interestingly, these properties are also observed in 2 other C. elegans globins that appear to be involved in redox biology. We therefore hypothesize that globins involved in redox signaling display similar structural and biochemical characteristics and propose that a subgroup of globins can be added to the group of proteins that play a vital role in redox signaling. PMID- 27695652 TI - Current advances in the functional studies of fatty acids and fatty acid-derived lipids in C. elegans. AB - Fatty acids and fatty acid-derived lipids (FAs/FADLs) play essential roles in many living organisms, including contributions to membrane structure and signaling transduction. Aberrant metabolism of FAs/FADLs often causes diseases and health problems. However, the detailed mechanistic studies of specific FAs/FADLs in vivo are limited. C. elegans has been an effective model system for FA/ FADL studies due to its powerful genetics and conserved lipid biosynthetic pathways. The recently developed high-throughput analytic tools also enable sophisticated profiling of lipids molecules in C. elegans, which is critical for understanding their specific functions. Here we review a subset of current advances in FA/FADL functional studies in C. elegans. PMID- 27695654 TI - Gamete interactions require transmembranous immunoglobulin-like proteins with conserved roles during evolution. AB - C. elegans spe-9 class genes are male germline-enriched in their expression and indispensable during sperm-oocyte fusion. Identification of mammalian orthologs that exhibit similar functions to these C. elegans genes has been a challenge. The mouse Izumo1 gene encodes a sperm-specific, immunoglobulin (Ig)-like transmembrane (TM) protein that is required for gamete fusion. We recently identified the C. elegans spe-45 gene, which shows male germline-enriched expression and encodes an Ig-like TM protein. spe-45 mutant worms produced otherwise normal spermatozoa that cannot fuse with oocytes, causing essentially the same phenotype as that seen in the Izumo1-knockout mice. By counting the number of self-sperm in the spermatheca of spe-45 hermaphrodites, it was found that this gene might be involved in sperm guidance from the uterus into the spermatheca, as well as gamete fusion. Moreover, we discovered that SPE-45 and IZUMO1 share certain functions for gamete fusion, which are presumably related to binding with cis- and/or trans-partners. Intriguingly, various organisms have Ig like TM proteins that act during gamete interactions, indicating the wide-spread utility of Ig-like domains during fertilization. PMID- 27695653 TI - Mechanism of chromatin segregation to the nuclear periphery in C. elegans embryos. AB - In eukaryotic organisms, gene regulation occurs in the context of chromatin. In the interphase nucleus, euchromatin and heterochromatin occupy distinct space during cell differentiation, with heterochromatin becoming enriched at the nuclear and nucleolar peripheries. This organization is thought to fine-tune gene expression. To elucidate the mechanisms that govern this level of genome organization, screens were carried out in C. elegans which monitored the loss of heterochromatin sequestration at the nuclear periphery. This led to the identification of a novel chromodomain protein, CEC-4 (Caenorhabditis elegans chromodomain protein 4) that mediates the anchoring of H3K9 methylation-bearing chromatin at the nuclear periphery in early to mid-stage embryos. Surprisingly, the loss of CEC-4 does not derepress genes found in heterochromatic domains, nor does it affect differentiation under standard laboratory conditions. On the other hand, CEC-4 contributes to the efficiency with which muscle differentiation is induced following ectopic expression of the master regulator, HLH-1. This is one of the first phenotypes specifically attributed to the ablation of heterochromatin anchoring. PMID- 27695655 TI - Probing and rearranging the transcription factor network controlling the C. elegans endoderm. AB - The ELT-2 GATA factor is the predominant transcription factor regulating gene expression in the C. elegans intestine, following endoderm specification. We comment on our previous study (Wiesenfahrt et al., 2016) that investigated how the elt-2 gene is controlled by END-1, END-3 and ELT-7, the 3 endoderm specific GATA factors that lie upstream in the regulatory hierarchy. We also discuss the unexpected result that ELT-2, if expressed sufficiently early and at sufficiently high levels, can specify the C. elegans endoderm, replacing the normal functions of END-1 and END-3. PMID- 27695657 TI - Cognitive Behavioral Therapy for Insomnia and Imagery Rehearsal in Combat Veterans with Comorbid Posttraumatic Stress: A Case Series. AB - Disrupted sleep is common among combat veterans and can negatively impact response to mental health treatments. A trial of cognitive behavioral therapy for insomnia (CBT-I) and imagery rehearsal therapy (IRT) for nightmares was conducted with 14 combat veterans diagnosed with insomnia, and who were experiencing posttraumatic stress and/or depression. In the case-series that follows veterans experienced clinically significant changes in sleep, and statistically significant reductions in insomnia, nightmare, depression and posttraumatic stress severity following treatment. Combined CBT-I and IRT is a promising treatment for patients with combat-related trauma and psychiatric morbidity. PMID- 27695656 TI - Leveraging the withered tail tip phenotype in C. elegans to identify proteins that influence membrane properties. AB - The properties of cellular membranes are critical for most cellular functions and are influenced by several parameters including phospholipid composition, integral and peripheral membrane proteins, and environmental conditions such as temperature. We previously showed that the C. elegans paqr-2 and iglr-2 mutants have a defect in membrane homeostasis and exhibit several distinct phenotypes, including a characteristic tail tip defect and cold intolerance. In the present study we report that screening for novel mutants with these 2 defects can lead to the identification of genes that are important contributors to membrane properties. In particular we isolated 3 novel alleles of sma-1, the C. elegans homolog of betaH spectrin, and 2 novel alleles of dpy-23, which encodes the C. elegans homolog of the AP2 MU subunit. We also show that sma-1 and dpy-23 act on membrane properties in pathways distinct from that of paqr-2 and iglr-2. PMID- 27695658 TI - Acetaminophen Use for Fever in Children Associated with Autism Spectrum Disorder. AB - Autism Spectrum Disorder (ASD) is characterized by persistent deficits in social communication and restrictive behavior, interests, and activities. Our previous case-control study showed that use of acetaminophen at age 12-18 months is associated with increased likelihood for ASD (OR 8.37, 95% CI 2.08-33.7). In this study, we again show that acetaminophen use is associated with ASD (p = 0.013). Because these children are older than in our first study, the association is reversed; fewer children with ASD vs. non-ASD children use acetaminophen as a "first choice" compared to "never use" (OR 0.165, 95% CI 0.045, 0.599). We found significantly more children with ASD vs. non- ASD children change to the use of ibuprofen when acetaminophen is not effective at reducing fever (p = 0.033) and theorize this change in use is due to endocannabinoid system dysfunction. We also found that children with ASD vs. non-ASD children are significantly more likely to show an increase in sociability when they have a fever (p = 0.037) and theorize that this increase is due to anandamide activation of the endocannabinoid system in ASD children with low endocannabinoid tone from early acetaminophen use. In light of this we recommend that acetaminophen use be reviewed for safety in children. PMID- 27695659 TI - Connecting Gender, Race, Class, and Immigration Status to Disease Management at the Workplace. AB - OBJECTIVE: Chronic diseases are the leading causes of death in the United States. Chronic disease management occurs within all aspects of an individual's life, including the workplace. Though the social constructs of gender, race, class, and immigration status within the workplace have been considered, their connection to disease management among workers has been less explicitly explored. Using a sample of immigrant hotel housekeepers, we explored the connections between these four social constructs and hypertension management. METHODS: This qualitative research study was guided by critical ethnography methodology. Twenty-seven hotel room cleaners and four housemen were recruited (N = 31) and invited to discuss their experiences with hypertension and hypertension management within the context of their work environments. RESULTS: Being a woman worker within the hotel industry was perceived to negatively influence participants' experience with hypertension and hypertension management. In contrast, being a woman played a protective role outside the workplace. Being an immigrant played both a positive and a negative role in hypertension and its management. Being black and from a low socioeconomic class had only adverse influences on participants' experience with hypertension and its management. CONCLUSION: Being a woman, black, lower class, and an immigrant simultaneously contribute to immigrant hotel housekeepers' health and their ability to effectively manage their hypertension. The connection between these four constructs (gender, race, class, and immigration status) and disease management must be considered during care provision. Hotel employers and policy stakeholders need to consider those constructs and how they impact workers' well-being. More studies are needed to identify what mitigates the associations between the intersectionality of these constructs and immigrant workers' health and disease management within their work environment. PMID- 27695660 TI - Psychiatric Genetics in Child Custody Proceedings: Ethical, Legal, and Social Issues. AB - This paper considers the ethical, legal, and social issues raised by the prospect of increasing use of psychiatric genetic data in child custody litigation. Although genetic tests cannot currently confirm a parent or child's psychiatric diagnosis, it is likely that as relevant findings emerge, they will be introduced in family courts to challenge parental capacity. Here, we draw on three projected, but plausible, scenarios for obtaining psychiatric data about parents - imposed genetic testing, access to medical records, and genetic theft -- then consider the use of psychiatric genetic data of children, to highlight the issues that judges, child custody evaluators, and clinicians who may provide treatment for parents or children with mental health issues will need to consider. These include: genetic privacy, stigma, genetic surveillance, and judicial and health professionals' bias. We argue that the unchecked introduction of psychiatric genetic data may have a detrimental effect on the administration of justice. In particular, the article highlights the risk that the (mis)use of psychiatric genetic data in custody disputes would 1) exacerbate stigma and treatment avoidance among parents and incentivize privacy violations to pressure parents to relinquish parental rights; 2) disproportionately affect poor parents and single mothers of color involved with Child Protective Services; and 3) detract attention from social and environmental factors impacting mental health to the detriment of the families involved. Awareness of these issues and an understanding of the meaning of genomic data by judges and custody evaluators will be pivotal in ensuring that justice is served. PMID- 27695662 TI - A Systematic Approach to Preclinical Trials in Metastatic Breast Cancer. AB - The process of developing new agents for therapy against breast cancer is inefficient and relies on animal models to screen for efficacy for preclinical studies. However, there has been limited validation of these models, despite the increasing costs in the rapidly growing era of personalized medicine and targeted therapy. Recently, there have been multiple studies which have critically evaluated animal models for breast cancer drug discovery. We recently reviewed the transgenic, xenograft, and syngeneic murine breast cancer models, the ectopic, orthotopic and intravenous methods of cell implantation, tumor gene expression profiles, as well as the ethics of animal experimentation, and we provide important information for investigators in this challenging field. Because of the complexities of treating breast cancer and the increasing costs of developing new agents, the choice of the appropriate murine model must carefully consider each model available, including the tumor gene expression profile. Such a critical approach to the in vivo portion of drug development will further increase the efficiency of breast cancer drug research and development. PMID- 27695661 TI - Staufen1s role as a splicing factor and a disease modifier in Myotonic Dystrophy Type I. AB - In a recent issue of PLOS Genetics, we reported that the double-stranded RNA binding protein, Staufen1, functions as a disease modifier in the neuromuscular disorder Myotonic Dystrophy Type I (DM1). In this work, we demonstrated that Staufen1 regulates the alternative splicing of exon 11 of the human Insulin Receptor, a highly studied missplicing event in DM1, through Alu elements located in an intronic region. Furthermore, we found that Staufen1 overexpression regulates numerous alternative splicing events, potentially resulting in both positive and negative effects in DM1. Here, we discuss our major findings and speculate on the details of the mechanisms by which Staufen1 could regulate alternative splicing, in both normal and DM1 conditions. Finally, we highlight the importance of disease modifiers, such as Staufen1, in the DM1 pathology in order to understand the complex disease phenotype and for future development of new therapeutic strategies. PMID- 27695663 TI - Adolescent Cellphone Use While Driving: An Overview of the Literature and Promising Future Directions for Prevention. AB - Motor vehicle crashes are the leading cause of death in adolescents, and drivers aged 16-19 are the most likely to die in distracted driving crashes. This paper provides an overview of the literature on adolescent cellphone use while driving, focusing on the crash risk, incidence, risk factors for engagement, and the effectiveness of current mitigation strategies. We conclude by discussing promising future approaches to prevent crashes related to cellphone use in adolescents. Handheld manipulation of the phone while driving has been shown to have a 3 to 4-fold increased risk of a near crash or crash, and eye glance duration greater than 2 seconds increases crash risk exponentially. Nearly half of U.S. high school students admit to texting while driving in the last month, but the frequency of use according to vehicle speed and high-risk situations remains unknown. Several risk factors are associated with cell phone use while driving including: parental cellphone use while driving, social norms for quick responses to text messages, and higher levels of temporal discounting. Given the limited effectiveness of current mitigation strategies such as educational campaigns and legal bans, a multi-pronged behavioral and technological approach addressing the above risk factors will be necessary to reduce this dangerous behavior in adolescents. PMID- 27695664 TI - I can't wait: Methods for measuring and moderating individual differences in impulsive choice. AB - Impulsive choice behavior occurs when individuals make choices without regard for future consequences. This behavior is often maladaptive and is a common symptom in many disorders, including drug abuse, compulsive gambling, and obesity. Several proposed mechanisms may influence impulsive choice behavior. These mechanisms provide a variety of pathways that may provide the basis for individual differences that are often evident when measuring choice behavior. This review provides an overview of these different pathways to impulsive choice, and the behavioral intervention strategies being developed to moderate impulsive choice. Because of the compelling link between impulsive choice behavior and the near-epidemic pervasiveness of obesity in the United States, we focus on the relationship between impulsive choice behavior and obesity as a test case for application of the multiple pathways approach. Choosing immediate gratification over healthier long term food choices is a contributing factor to the obesity crisis. Behavioral interventions can lead to more self controlled choices in a rat pre-clinical model, suggesting a possible gateway for translation to human populations. Designing and implementing effective impulsive choice interventions is crucial to improving the overall health and well-being of impulsive individuals.

AB - Alexithymia, characterized by impairments in emotional awareness, is common among individuals with substance use disorders. Research on alexithymia suggests that it is a trait that may contribute to substance dependence. This paper will review alexithymia as it relates to substance use and substance use disorders, considering its potential role in the maintenance and treatment of these disorders. We will then describe how neural correlates associated with alexithymia may shed light on how alexithymia relates to addiction. Finally, we present preliminary fMRI data that examines how alexithymia may relate to the neurobiological correlates of reward/loss processing in individuals with cocaine dependence. While preliminary, these findings suggest a role of alexithymia in reward anticipation in cocaine-dependent individuals.

AB - Serial block-face scanning electron microscopy (SBEM) is quickly becoming an important imaging tool to explore three-dimensional biological structure across spatial scales. At probe-beam-electron energies of 2.0 keV or lower, the axial resolution should improve, because there is less primary electron penetration into the block face. More specifically, at these lower energies, the interaction volume is much smaller, and therefore, surface detail is more highly resolved. However, the backscattered electron yield for metal contrast agents and the backscattered electron detector sensitivity are both sub-optimal at these lower energies, thus negating the gain in axial resolution. We found that the application of a negative voltage (reversal potential) applied to a modified SBEM stage creates a tunable electric field at the sample. This field can be used to decrease the probe-beam-landing energy and, at the same time, alter the trajectory of the signal to increase the signal collected by the detector. With decelerated low landing-energy electrons, we observed that the probe-beam electron-penetration depth was reduced to less than 30 nm in epoxy-embedded biological specimens. Concurrently, a large increase in recorded signal occurred due to the re-acceleration of BSEs in the bias field towards the objective pole piece where the detector is located. By tuning the bias field, we were able to manipulate the trajectories of the primary and secondary electrons, enabling the spatial discrimination of these signals using an advanced ring-type BSE detector configuration or a standard monolithic BSE detector coupled with a blocking aperture.

AB - Social interaction and communication are complex behavioral paradigms involving many components. Many different neurotransmitters, hormones, sensory inputs, and brain regions are involved in the act of social engagement and verbal or nonverbal communication. Autism Spectrum Disorder (ASD) and schizophrenia are two neurodevelopmental disorders that have social and language deficits as hallmark symptoms, but show very different etiologies. The output of social dysfunction is common to both ASD and schizophrenia, but this likely arises from very different pathophysiological means. This review will attempt to compile and interpret human and animal studies showing the neurobiological basis for the development of social and language deficits in ASD and schizophrenia as well as a comparison of the two disorders. PMID- 27695668 TI - The association between maternal nutrition and lifestyle during pregnancy and 2 year-old offspring adiposity: analysis from the ROLO study. AB - AIM: To examine the association between maternal nutrition and lifestyle factors and offspring adiposity, using baseline and 2-year postpartum follow-up data from a randomised control trial of low glycaemic index diet. SUBJECT AND METHODS: Food diaries and lifestyle questionnaires were completed during pregnancy and infant feeding and maternal lifestyle questionnaires 2 years postpartum for 281 mother and infant pairs from the ROLO study. Maternal anthropometry was measured throughout pregnancy and infant and maternal anthropometry was measured 2 years postpartum. RESULTS: Maternal 2 year postpartum body mass index (BMI) was positively associated with offspring BMI-for-age z-score (B = 0.105, p = 0.015). Trimester 2 saturated fat intake was positively associated with offspring subscapular:triceps skinfold ratio (B = 0.018, p = 0.001). Trimester 1 glycaemic index was also positively associated with offspring sum of subscapular and triceps skinfolds (B = 0.009, p = 0.029). CONCLUSIONS: Maternal BMI 2 years postpartum was positively associated with offspring BMI. Pregnancy saturated fat intake was positively and polyunsaturated fat negatively associated with offspring adiposity. While further research is necessary, pregnancy and the postpartum period may be early opportunities to combat childhood obesity. PMID- 27695669 TI - Environmental determinants of aplastic anemia in Pakistan: a case-control study. AB - AIM: Aplastic anemia (AA) affects the Asian population two to three fold more than people in other regions. Besides the host genetics and socioeconomic status, several other environmental exposures have been linked with an AA etiology. We aimed to examine the association of various environmental exposures with AA occurrence among Pakistani individuals. SUBJECTS AND METHODS: A case-control study was conducted in Karachi, Pakistan, where cases (diagnosed AA patients) were selected from the National Institute of Blood Disease and Bone Marrow Transplantation (NIBD), while for each case, a single control (who was free of AA and visited the outpatient department of the same hospital for the treatment of minor ailments) was selected matched by age and sex. A total of 428 participants were included in this study with equal proportions of cases and controls. Information related to disease characteristics, sociodemographics and exposure to chemicals was collected through a survey questionnaire, laboratory investigations and medical records. Descriptive results were reported as frequencies and proportions, adjusted odds ratios with 95 % confidence intervals and population attributable risk (PAR) as percentage. RESULTS: Among study participants (n = 428), AA was significantly associated with various environmental exposures. Participants residing in rural settings (OR = 2.29, 95 % CI 1.12-4.67, p-value < 0.01) and those who reported exposure to pesticides (OR = 3.58, 95 % CI 1.27 10.10, p-value 0.01; PAR = 18.16 %) were significantly more likely to report AA. Participants with a formal education were significantly less likely to have AA (OR = 0.27, 95 % CI 0.10-0.71, p-value < 0.01). CONCLUSIONS: This study observed a significant association of aplastic anemia with a lower socioeconomic profile, and certain environmental exposures among the Pakistani population. The evidence may be helpful in understanding the pathophysiology of aplastic anemia in the context of environmental exposures. PMID- 27695670 TI - Prognostic significance of novel katG mutations in Mycobacterium tuberculosis. AB - BACKGROUND: By using whole genome sequencing (WGS), researchers are beginning to understand the genetic diversity of Mycobacterium tuberculosis (MTB) and its consequences for the diagnosis of multidrug-resistant tuberculosis (MDR-TB) on a genomic scale. The Global Consortium for Drug-resistant TB Diagnostics (GCDD) conducted a genome scale variant analyses of 366 clinical MTB genomes (mostly MDR/XDR [extensively drug resistant]) from four countries in order to inform the development of rapid molecular diagnostics. This project has been extended by performing an evolutionary analysis of isoniazid (INH)-resistant isolates for prognostic purposes. METHODS: 151 (130 INHR, 21 INHS) clinical MTB isolates from India (19: 17 INHR, 2 INHS), Moldova (48: 42 INHR, 6 INHS), the Philippines (26: 20 INHR, 6 INHS), and South Africa (58: 51 INHR, 7 INHS) were included in this study. INH drug susceptibility was determined by using MGIT 960 and WHO (World Health Organization)-recommended critical concentration of 0.1 mg/L. Isolates were sequenced using PacBio RS WGS platform. A genome-wide variant analysis was conducted using a proprietary pipeline (PacDAP) developed at San Diego State University. To infer the amino acid changes in katG that confer resistance, PAML was utilized to detect sites in silico that are under positive selection. The dN/dS method was used in combination with Bayes empirical Bayes to determine sites under positive selection and Chi-Squared analysis to determine the significance of the selected sites. RESULTS: PacDAP variant analysis revealed 22 novel catalase-peroxidase (katG product) mutations. Of these, 14 were single nucleotide polymorphisms, while 8 novel mutations appeared in combination with katG S315T and/or with inhA promoter C-15T. These SNPs have not been previously reported. Additionally, 11 previously observed, but uncommon, katG mutations were also observed in these clinical isolates. These results suggest that 17 amino acids in the enzyme are under positive selective pressure; most significantly in South Africa and the Philippines. No selective pressure on codons other than 315 was observed in isolates from Moldova. Due to the low number of isolates from India, the significance of the sites under positive selection was low and no prediction for India could be made based on this study. CONCLUSIONS: Eleven of the 14 SNPs are resistance conferring, and it is believed that the remaining 8 combinatorial mutations are either compensatory in nature or, in combination with known SNPs, could increase resistance levels. Positive selection results indicate a diversifying evolutionary path to resistance more in line with long tail statistics and therefore indicate a departure from the traditional point mutation (or "hotspot") model that current molecular diagnostics are based on. Positive selection pressures indicate a future with elevated diagnostic and prognostic significance of the "long tail" (i.e., alternative mechanisms of resistance) and potentially diminishing significance of the canonical mutations (especially in South Africa and the Philippines), which could have significant future implications on narrowly targeting molecular diagnostics.

AB - It is well known that surfactant-suspended carbon nanotube (CNT) samples can be purified by centrifugation to decrease agglomerates and increase individually dispersed CNTs. However, centrifugation is not always part of protocols to prepare CNT samples used in biomedical applications. Herein, using carboxylated multi-walled CNTs (cMWCNTs) suspended in water without a surfactant, we developed a Boehm titrimetric method for the analysis of centrifuged cMWCNT suspensions and used it to show that the surface acidity of oxidized carbon materials in aqueous cMWCNT suspensions was enriched by ~40% by a single low-speed centrifugation step. This significant difference in surface acidity between un-centrifuged and centrifuged cMWCNT suspensions has not been previously appreciated and is important because the degree of surface acidity is known to affect the interactions of cMWCNTs with biological systems. PMID- 27695673 TI - Extensive subclinical sinusitis leading to Moraxella osloensis meningitis. AB - We report a case of a 31 year old male with extensive subclinical sinusitis leading to erosion in the cribriform plate and subsequent meningitis caused by the organism Moraxella osloensis. The patient presented to the emergency department with rapid onset confusion, neck stiffness and headache. Inflammatory markers, renal and liver function, and a chest radiograph were all normal. CT Head showed extensive polyp disease in the paranasal sinuses with expansion of the left frontal sinus and CT Sinuses revealed an area of low attenuation in the cribriform plate consistent with bony erosion. MRI Head showed thick loculated sinus inflammation. Lumbar puncture yielded CSF with a high white cell count of predominantly mononuclear cells, no visible organisms and an elevated protein. CSF microscopy, culture and viral PCR were not diagnostic, and so the CSF was sent for 16S rDNA PCR screening, which identified the rDNA of Moraxella osloensis. Moraxella osloensis is a rare cause of bacterial meningitis, with only a few reported cases. This case illustrates that sinusitis, while a common condition, when severe can predispose to intracranial infection with atypical and low virulence organisms such as Moraxella species, which do not commonly cause invasive CNS disease. This case represents the first case of Moraxella osloensis meningitis reported from the United Kingdom.

AB - Magnesium (Mg)-based biodegradable materials are promising candidates for the new generation of implantable medical devices, particularly cardiovascular stents and orthopaedic implants. Mg-based cardiovascular stents represent the most innovative stent technology to date. However, these products still do not fully meet clinical requirements with regards to fast degradation rates, late restenosis, and thrombosis. Thus various surface coatings have been introduced to protect Mg-based stents from rapid corrosion and to improve biocompatibility. Similarly, different coatings have been used for orthopaedic implants, e.g., plates and pins for bone fracture fixation or as an interference screw for tendon bone or ligament-bone insertion, to improve biocompatibility and corrosion resistance. Metal coatings, nanoporous inorganic coatings and permanent polymers have been proved to enhance corrosion resistance; however, inflammation and foreign body reactions have also been reported. By contrast, biodegradable polymers are more biocompatible in general and are favoured over permanent materials. Drugs are also loaded with biodegradable polymers to improve their performance. The key similarities and differences in coatings for Mg-based stents and orthopaedic implants are summarized. PMID- 27695674 TI - Characteristics of mucoid Streptococcus pyogenes isolated from two patients with pneumonia in a local community. AB - Streptococcus pyogenes (Group A Streptococcus, GAS) infections can develop into life-threatening disorders. However, the occurrence of some GAS pneumonia cases is relatively rare in a local community. We report here characteristics of mucoid GAS isolates obtained from the sputum of two patients with pneumonia in a local community. Although case-patients did not have contact with each other, case patient 1's child and case-patient 2's grandchild attended the same kindergarten where a GAS pharyngitis epidemic had occurred. We conducted phenotypic and genotypic analyses with the GAS isolates from sputum of both patients, to examine (1) colony appearance between the isolates, (2) numerical profile based on API-20 Strep system, (3) similarity to the type strain using 16S rRNA sequencing, (4) emm type (subtype) and emm full-length sequence, (5) sequence type, (6) sic allele, (7) antimicrobial susceptibility result and the resistance determinant, (8) genome profile following a random amplified polymorphic DNA fragments, and (9) pattern of digested DNA fragments by pulse-field gel electrophoresis. These phenotypic and genotypic analyses revealed similar matching between the isolates from both cases. Our findings suggest that when clinicians examine adult patients having infection with the mucoid GAS, they should confirm whether anyone within the same household also developed the infection and need to investigate epidemic situations in local communities, including kindergartens and elementary schools.

PMID- 27695675 TI - Theory of Mind, Emotion Recognition and Social Perception in Individuals at Clinical High Risk for Psychosis: findings from the NAPLS-2 cohort. AB - Social cognition, the mental operations that underlie social interactions, is a major construct to investigate in schizophrenia. Impairments in social cognition are present before the onset of psychosis, and even in unaffected first-degree relatives, suggesting that social cognition may be a trait marker of the illness. In a large cohort of individuals at clinical high risk for psychosis (CHR) and healthy controls, three domains of social cognition (theory of mind, facial emotion recognition and social perception) were assessed to clarify which domains are impaired in this population. Six-hundred and seventy-five CHR individuals and 264 controls, who were part of the multi-site North American Prodromal Longitudinal Study, completed The Awareness of Social Inference Test, the Penn Emotion Recognition task, the Penn Emotion Differentiation task, and the Relationship Across Domains, measures of theory of mind, facial emotion recognition, and social perception, respectively. Social cognition was not related to positive and negative symptom severity, but was associated with age and IQ. CHR individuals demonstrated poorer performance on all measures of social cognition. However, after controlling for age and IQ, the group differences remained significant for measures of theory of mind and social perception, but not for facial emotion recognition. Theory of mind and social perception are impaired in individuals at CHR for psychosis. Age and IQ seem to play an important role in the arising of deficits in facial affect recognition. Future studies should examine the stability of social cognition deficits over time and their role, if any, in the development of psychosis. PMID- 27695677 TI - Highlighting the need for more infection control practitioners in low- and middle income countries. AB - Background: Many low- and middle-income countries struggle to implement, monitor and evaluate the efficacy of infection control (IC) measures within health care facilities. This hampers their ability to prevent nosocomial infections, identify emerging pathogens and rapidly alert officials to possible outbreaks. The lack of dedicated and trained IC practitioners (ICPs) is a serious deficit in the health care workforce, and is worsened by the lack of institutions that offer IC training. Discussion: While no single individual can entirely eliminate the risk of nosocomial transmission, there is literature to support the value of designated IC persons. Recommendations from the World Health Organization in 2008 and 2009 describe the need for this specialized cadre of workers, but many countries lack the national regulations to authorize, train and manage such professionals at the national or local level. This article provides an overview of how ICPs are trained and credentialed in several countries, and discusses approaches countries can use to train ICPs. Conclusion: Trained ICPs can help prevent future outbreaks and control nosocomial transmission of diseases in health care facilities. For this to occur, supportive national policies, availability of training institutions and local administrative support will be required. PMID- 27695678 TI - Declining tuberculosis case notification rates with the scale-up of antiretroviral therapy in Zimbabwe. AB - Setting: Zimbabwe has a human immunodeficiency virus (HIV) driven tuberculosis (TB) epidemic, with antiretroviral therapy (ART) scaled up in the public sector since 2004. Objective: To determine whether national ART scale-up was associated with annual national TB case notification rates (CNR), stratified by disease type and category, between 2000 and 2013. Design: This was a retrospective study using aggregate data from global reports. Results: The number of people living with HIV and retained on ART from 2004 to 2013 increased from 8400 to 665 299, with ART coverage increasing from <0.5% to 48%. TB CNRs, all types and categories, increased from 2000 to 2003, and declined thereafter from 2004 to 2013. The decreases in annual TB notifications between the highest rates (before 2004) and lowest rates (2013) were all forms of TB (56%), new TB (60%), previously treated TB (53%), new smear-positive pulmonary TB (PTB) (40%), new smear-negative/smear unknown PTB (58%) and extra-pulmonary TB (58%). Conclusion: Significant declines in TB CNRs were observed during ART scale-up, especially for smear-negative PTB and extra-pulmonary TB. These encouraging national trends support the continued scale-up of ART for people living with HIV as a way of tackling the twin epidemics of HIV/acquired immune-deficiency syndrome and TB in Zimbabwe. PMID- 27695680 TI - Did FIDELIS projects contribute to the detection of new smear-positive pulmonary tuberculosis cases in China? AB - Setting: The first phase of the Fund for Innovative DOTS Expansion through Local Initiatives to Stop TB (FIDELIS) projects in China started in 2003. Objective: To determine whether the FIDELIS projects contributed to the increased case detection rate for new smear-positive pulmonary tuberculosis (PTB) in China. Methods: We compared the case notification rates (CNRs) in the intervention year with those of the previous year in the FIDELIS areas, then compared the difference between the CNRs of the intervention year and the previous year in the FIDELIS areas with those in the non-FI-DELIS areas within the province. Results: There was an increase in the CNR in the intervention year compared with the previous year for all the project sites. The differences between the CNR in the intervention year and the previous year ranged from 6.4 to 31.1 per 100 000 population in the FIDELIS areas and from 2.9 to 20.4/100 000 in the non-FIDELIS areas. Differences-in-differences analysis shows that the differences in the CNRs in the FIDELIS areas were not statistically significantly different from those in the non-FIDELIS areas (P = 0.393). Conclusion: The FIDELIS projects may have contributed to the increase in case detection of new smear-positive PTB in China, but the level of evidence is low. PMID- 27695679 TI - Dotting the Three I's for collaborative TB-HIV activities: evaluation of a pilot programme in Kathmandu, Nepal. AB - Setting: The three government tertiary care hospitals providing care for people living with the human immunodeficiency virus (PLHIV) in Kathmandu, Nepal. Objectives: To assess 1) the screening cascades for intensified case finding for tuberculosis (TB), 2) isoniazid preventive therapy (IPT), including demographic and clinical factors associated with treatment interruption, and 3) TB infection control (IC) in the health facilities. Design: A cross-sectional study of new PLHIV enrolled from January 2012 to December 2014. Results: Among 572 registered PLHIV, 91% were on antiretroviral therapy. Of those registered, 561 (98%) were screened for TB and 73 (13%) were diagnosed with TB (17 [25%] sputum smear positive, 17 [25%] smear-negative and 35 [51%] extra-pulmonary). Among the 488 (87%) PLHIV without active TB, 157 (32%) were initiated on IPT, of whom 136 (87%) completed treatment and 17 (11%) interrupted treatment. Those who experienced adverse events were 12 times more likely to interrupt IPT. TB IC showed gaps in personal control measures and supporting structures and policies. Conclusion: The implementation of the Three I's for collaborative TB-HIV activities in pilot sites in Nepal was successful and should be scaled up. PMID- 27695681 TI - Health service perceptions about implementation of a new TB diagnostic in Northern Russia: a qualitative study. AB - Setting: Many tuberculosis services are implementing new diagnostics to accelerate treatment initiation for multidrug-resistant tuberculosis. Successful implementation and uptake are likely to depend on many factors. Objective: To describe the perceptions of the Arkhangelsk health services staff in Northern Russia on the process of introducing the line-probe assay and to determine what facilitates the process of uptake into practice. Design: Process evaluation; semi structured, in-depth interviews with key informants from civil and penitentiary health services; content analysis. Results: A good working relationship between the civil and penitentiary sectors and a tradition of positive collaboration between doctors and managers were integral to success. Uptake and adaptation were facilitated by regular discussions between managers and implementers, flexibility in adapting routines and an iterative approach to improving procedures. It is beneficial to allow all types of health care workers affected by the diagnostic to learn about it and contribute to its integration. A multidisciplinary evaluation can detect problems elsewhere in the care pathway. Bringing about change in workplace mind-sets and attitudes takes time and management. Conclusion: People take time to observe the effects of innovations, assess relative advantages and become convinced, sometimes by different types of evidence. Multi-disciplinary opportunities for learning, reflecting on care pathways and adaptation should all be a part of introducing new diagnostics. PMID- 27695682 TI - The experience of bedaquiline implementation at a decentralised clinic in South Africa. AB - Multidrug-resistant tuberculosis (MDR-TB) is a serious public health problem, but the new drugs bedaquiline (BDQ) and delamanid offer hope to improve outcomes and minimise toxicity. In Khayelitsha, South Africa, patients are routinely started on BDQ in the out-patient setting. This report from the field describes BDQ use in the out-patient setting at the Nolungile Clinic. The clinic staff overall report a positive experience using the drug. Challenges have been based largely on the logistics of drug supply and delivery. BDQ can be started successfully in the out-patient setting, and can be a positive experience for both patients and providers. La tuberculose multiresistante (TB-MDR) est un probleme de sante publique grave, mais les nouveaux medicaments que sont la bedaquiline (BDQ) et le delamanide apportent un espoir d'ameliorer les resultats tout en reduisant la toxicite. A Khayelitsha, Afrique du Sud, les patients demarrent leur traitement par BDQ en consultation externe en routine. Ce rapport du terrain decrit l'utilisation de la BDQ a la consultation externe du dispensaire Nolungile. Dans l'ensemble, le personnel du centre de sante exprime une experience positive du medicament. Les defis ont surtout ete lies a la logistique de l'approvisionnement et de la distribution du medicament. La BDQ peut etre mise en route avec succes dans le cadre d'une consultation externe et peut constituer une experience positive pour les patients et les prestataires de soins. La tuberculosis multirresistente (TB-MDR) representa un grave problema de salud publica, pero la utilizacion de nuevos medicamentos como la bedaquilina (BDQ) y el delamanid ofrece perspectivas de mejores desenlaces terapeuticos y disminucion de la toxicidad asociada.

En el presente informe del terreno, se describe la utilizacion de BDQ en tratamiento antituberculoso ambulatorio en el centro de atencion Nolungile. En general, los miembros del personal del centro refirieron una experiencia positiva con la administracion del medicamento. Las dificultades surgieron en gran parte con respecto a aspectos logisticos del suministro y la administracion del medicamento. Es posible iniciar un tratamiento eficaz con BDQ en condiciones ambulatorias, y represente una experiencia positiva para los pacientes y los profesionales de salud. PMID- 27695683 TI - Surgical interventions for pulmonary tuberculosis in Mumbai, India: surgical outcomes and programmatic challenges. AB - Setting: While surgery for pulmonary tuberculosis (PTB) is considered an important adjunct for specific cases, including drug-resistant tuberculosis, operational evidence on its feasibility and effectiveness is limited. Objective: To describe surgical outcomes and programmatic challenges of providing surgery for PTB in Mumbai, India. Design: A descriptive study of routinely collected data of surgical interventions for PTB from 2010 to 2014 in two Mumbai hospitals, one public, one private. Results: Of 85 patients, 5 (6%) died and 17 (20%) had complications, with wound infection being the most frequent. Repeat operation was required in 12 (14%) patients. Most procedures were performed on an emergency basis, and eligibility was established late in the course of treatment. Median time from admission to surgery was 51 days. Drug susceptibility test (DST) patterns and final treatment outcomes were not systematically collected. Conclusion: In a high-burden setting such as Mumbai, important data on surgery for PTB were surprisingly limited in both the private and public sectors. Eligibility for surgery was established late, culture and DST were not systematically offered, the interval between admission and surgery was long and TB outcomes were not known. Systematic data collection would allow for proper evaluation of surgery as adjunctive therapy for all forms of TB under programmatic conditions. PMID- 27695684 TI - Chronic respiratory disease in adults treated for tuberculosis in Khartoum, Sudan. AB - Background: Chronic respiratory disease (CRD) causes substantial morbidity and mortality. Although the global CRD epidemic collides with the tuberculosis (TB) epidemic in many low- and middle-income country settings, the risk of TB associated CRD is not well described in countries with a high burden of TB. Methods: We recruited 136 patients with a history of sputum smear-positive pulmonary TB (PTB) from the TB clinic at Omdurman Teaching Hospital in Khartoum, Sudan, and 136 age- and sex-matched community controls, between 28 July 2013 and 30 December 2013. Data were collected using standardised questionnaires and spirometry was performed before and after bronchodilator. Results: The mean age of the subjects with previous PTB and controls was respectively 44.0 years (SD 8.5) and 44.5 years (SD 8.6), with 27.2% females in both groups. Chronic respiratory symptoms such as chronic cough (OR 6.67, 95%CI 2.98-14.90, P < 0.001) and the presence of chronic airflow obstruction (OR 12.4, 95%CI 1.56-98.40, P = 0.02) were both strongly associated with a past history of PTB after adjusting for potential confounders. Conclusion: The clinical features of CRDs are strongly associated with past history of PTB. An integrated approach to improve the management of these common conditions should be considered. Contexte : Les maladies respiratoires chroniques (MRC) sont a l'origine d'une morbidite et d'une mortalite considerables dans le monde. Bien que l'epidemie mondiale des MRC entre en conflit avec l'epidemie de tuberculose (TB) dans de nombreux pays a revenu faible ou moyen, le risque de MRC associee a la TB n'est pas bien decrit dans les pays durement frappes par la TB. Methodes : Nous avons recrute 136 patients ayant des antecedents de tuberculose pulmonaire (TBP) a frottis positif dans le service de pneumologie du Centre Hospitalier Universitaire Omdurman a Khartoum, Soudan, et 136 temoins de la communaute, apparies sur l'age et le sexe, entre le 28 juillet 2013 et le 30 decembre 2013. Les donnees ont ete recueillies grace a des questionnaires standardises ainsi qu'a une spirometrie avant et apres bronchodilatateur. Resultats : L'age moyen des cas et des temoins a ete de 44,0 ans (DS 8,5) et 44,5 ans (DS 8,61), respectivement, avec 27,2% de femmes dans les deux groupes. Des symptomes respiratoires chroniques comme une toux chronique (OR 6,67 ; IC95% 2,98-14,90 ; P < 0,001) et la presence d'une obstruction chronique des voies aeriennes (OR 12,39 ; IC%95 1,56-98,40 ; P = 0,02) ont ete tous deux fortement associes a des antecedents de TBP apres ajustement sur les facteurs de confusion potentiels. Conclusion : Les caracteristiques cliniques des MRC sont fortement associees a des antecedents de TBP. Une approche integree visant a ameliorer la prise en charge de ces pathologies frequentes devrait etre envisagee. Marco de referencia: La enfermedad pulmonar cronica (EPC) es una causa importante de morbilidad y mortalidad. Aunque la epidemia mundial de EPC rivaliza con la epidemia de tuberculosis (TB) en muchos entornos de paises con bajos y medianos recursos, el riesgo de aparicion de EPC asociado con la TB se ha descrito cabalmente en los paises con una alta carga de morbilidad por TB. Metodos: Entre el 28 de julio y el 30 de diciembre del 2013, participaron en el estudio 136 pacientes con antecedente de tuberculosis pulmonar (TBP) y baciloscopia positiva del esputo que habian recibido tratamiento en el consultorio de neumologia del Hospital Universitario Omdurman de Jartun, en Sudan, y 136 testigos sanos de la comunidad, emparejados en funcion de la edad y el sexo. Se recogieron datos mediante cuestionarios normalizados y se practico una espirometria antes y despues una prueba de broncodilatacion. Resultados: El promedio de la edad en el grupo de los casos fue 44,0 (desviacion estandar 8,5 anos) y en el grupo de testigos fue 44,5 anos (8,6 anos); la proporcion de mujeres en ambos grupos fue 27,2%. Se observo una fuerte asociacion entre la presencia de sintomas respiratorios cronicos como la tos (OR 6,67; IC95% 2,98 14,90; P < 0,001) y la presencia de obstruccion cronica al flujo en las vias respiratorias (OR 12,39; IC95% 1,56-98,40; P = 0,02) en las personas con antecedente de TBP, una vez corregidos los posibles factores de confusion. Conclusion: La presencia de rasgos clinicos de EPC exhibe una fuerte correlacion con el antecedente de TBP. Es preciso considerar la posibilidad de aplicar un enfoque integrado con el fin de mejorar la atencion de ambas enfermedades tan frecuentes.

AB - As tick-borne diseases are on the rise, an international effort resulted in the sequence and assembly of the first genome of a tick vector. This result promotes research on comparative, functional and evolutionary genomics and the study of tick-host-pathogen interactions to improve human, animal and ecosystem health on a global scale. PMID- 27695690 TI - Correlation of Antagonistic Regulation of leuO Transcription with the Cellular Levels of BglJ-RcsB and LeuO in Escherichia coli. AB - LeuO is a conserved and pleiotropic transcription regulator, antagonist of the nucleoid-associated silencer protein H-NS, and important for pathogenicity and multidrug resistance in Enterobacteriaceae. Regulation of transcription of the leuO gene is complex. It is silenced by H-NS and its paralog StpA, and it is autoregulated. In addition, in Escherichia coli leuO is antagonistically regulated by the heterodimeric transcription regulator BglJ-RcsB and by LeuO. BglJ-RcsB activates leuO, while LeuO inhibits activation by BglJ-RcsB. Furthermore, LeuO activates expression of bglJ, which is likewise H-NS repressed. Mutual activation of leuO and bglJ resembles a double-positive feedback network, which theoretically can result in bi-stability and heterogeneity, or be maintained in a stable OFF or ON states by an additional signal. Here we performed quantitative and single-cell expression analyses to address the antagonistic regulation and feedback control of leuO transcription by BglJ-RcsB and LeuO using a leuO promoter mVenus reporter fusion and finely tunable bglJ and leuO expression plasmids. The data revealed uniform regulation of leuO expression in the population that correlates with the relative cellular concentration of BglJ and LeuO. The data are in agreement with a straightforward model of antagonistic regulation of leuO expression by the two regulators, LeuO and BglJ RcsB, by independent mechanisms. Further, the data suggest that at standard laboratory growth conditions feedback regulation of leuO is of minor relevance and that silencing of leuO and bglJ by H-NS (and StpA) keeps these loci in the OFF state. PMID- 27695691 TI - Xanthogranulomatous prostatitis with prostato-rectal fistula: a case report and review of the literature. AB - PURPOSE: Xanthogranulomatous prostatitis (XP) is a rare form of nonspecific granulomatous prostatitis that can clinically mimic high-grade prostatic carcinoma. It is difficult to diagnose it definitely in clinical settings. METHODS: We report a case of XP with prostate-rectal fistula and review the relevant literatures. RESULT: A 75-year-old man presented with rectal bleeding when he urinated. A locally advanced carcinoma of prostate was suspected initially following the physical, imaging, and hematologic examinations. Subsequently on histopathological and immunohistochemical staining after needle biopsy of the prostate, a diagnosis of XP was made definitely. The patient was catheterized temporarily and treated with tamsulosin and estrogen. The patient underwent uneventful recovery after this conservative therapy. CONCLUSION: Histologic and immunohistochemical analyses are valuable in differentially diagnosing XP from high-grade prostate carcinoma. Treatment strategy of XP in principle is recommended to be the conservative method. Long-term follow-up earns are highly regarded considering the possibility of coexisting prostate cancer.

AB - Animal tissues are composed of multiple cell types arranged in complex and elaborate patterns. In sensory epithelia, including the auditory epithelium and olfactory epithelium, different types of cells are arranged in unique mosaic patterns. These mosaic patterns are evolutionarily conserved, and are thought to be important for hearing and olfaction. Recent progress has provided accumulating evidence that the cellular pattern formation in epithelia involves cell rearrangements, movements, and shape changes. These morphogenetic processes are largely mediated by intercellular adhesion systems. Differential adhesion and cortical tension have been proposed to promote cell rearrangements. Many different types of cells in tissues express various types of cell adhesion molecules. Although cooperative mechanisms between multiple adhesive systems are likely to contribute to the production of complex cell patterns, our current understanding of the cooperative roles between multiple adhesion systems is insufficient to entirely explain the complex mechanisms underlying cellular patterning. Recent studies have revealed that nectins, in cooperation with cadherins, are crucial for the mosaic cellular patterning in sensory organs. The nectin and cadherin systems are interacted with one another, and these interactions provide cells with differential adhesive affinities for complex cellular pattern formations in sensory epithelia, which cannot be achieved by a single mechanism. PMID- 27695693 TI - The First 500 Registrations to the Research Registry(r): Advancing Registration of Under-Registered Study Types. AB - INTRODUCTION: The Declaration of Helsinki 2013 encourages the registration of all research studies involving human participants. However, emphasis has been placed on prospective clinical trials, and it is estimated that only 10% of observational studies are registered. In response, Research Registry(r) was launched in February 2015; a retrospectively curated registry that is free and easy to use. Research Registry(r) enables prospective or retrospective registration of studies, including those study types that cannot be registered on existing registries. In this study, we describe the first 500 registrations on Research Registry(r). METHODS: Since the launch of Research Registry(r) in February 2015, data of registrations have been collected, including type of studies registered, country of origin, and data curation activity. Inappropriate registrations, such as duplicates, were identified by the data curation process. These were removed from the database or modified as required. A quality score was assigned for each registration, based on Sir Austin Bradford Hill's criteria on what research studies should convey. Changes in quality scores over time were assessed. RESULTS: A total of 500 studies were registered on Research Registry(r) from February 2015 to October 2015, with a total of 1.7 million patients enrolled. The most common study types were retrospective cohort studies (37.2%), case series (14.8%), and first-in-man case reports (10.4%). Registrations were received from 57 different countries; the most submissions were received from Turkey, followed by China and the United Kingdom. Retrospective data curation identified 80 studies that were initially registered as the incorrect study type, and were subsequently correct. The Kruskal-Wallis test identified a significant improvement in quality scores for registrations from February 2015 to October 2015 (p < 0.0001). CONCLUSIONS: Since its conception in February 2015, Research Registry(r) has established itself as a new registry that is free, easy to use, and enables the registration of various study types, including observational studies and first-in-man case reports. Going forward, our plan is to continue developing Research Registry(r) in line with user feedback and usability studies. We plan to further promote Research Registry(r) to advance the cause of registration of research, to increase compliance with the Declaration of Helsinki 2013.

AB - Superoxide dismutase 1 (SOD1) has been implicated with familial amyotrophic lateral sclerosis (fALS) through accumulation of protein amyloid aggregates in motor neurons of patients. Amyloid aggregates and protein inclusions are a common pathological feature of many neurological disorders in which protein aggregation seems to be directly related to neurotoxicity. Although, extensive studies performed on the aggregation process of several amyloidogenic proteins in vitro allowed the identification of many physiological factors involved, the molecular mechanisms underlying the formation of amyloid aggregates in vivo and in pathological conditions are still poorly understood. Post-translational modifications are known to affect protein structure and function and, recently, much attention has been devoted to the role played by non-enzymatic glycation in stimulating amyloid aggregation and cellular toxicity. In particular, glycation seems to have a determining role both in sporadic and familial forms of ALS and SOD1 has been shown to be glycated in vivo The aim of this study was to investigate the role of glycation on the amyloid aggregation process of both wild type SOD1 and its ALS-related mutant G93A. To this aim, the glycation kinetics of both native and demetalated SOD have been followed using two different glycating agents, i.e., D-ribose and methylglyoxal. The effect of glycation on the structure and the amyloid aggregation propensity of native and ApoSOD has been also investigated using a combination of biophysical and biochemical techniques. In addition, the effect of SOD glycated species on cellular toxicity and reactive oxygen species (ROS) production has been evaluated in different cellular models. The results provided by this study contribute to clarify the role of glycation in amyloid aggregation and suggest a direct implication of glycation in the pathology of fALS. PMID- 27695695 TI - A Comparison of Classical and H-Type Bovine Spongiform Encephalopathy Associated with E211K Prion Protein Polymorphism in Wild-Type and EK211 Cattle Following Intracranial Inoculation. AB - In 2006, a case of H-type bovine spongiform encephalopathy (BSE-H) was diagnosed in a cow that was associated with a heritable polymorphism in the bovine prion protein gene (PRNP) resulting in a lysine for glutamate amino acid substitution at codon 211 (called E211K) of the prion protein. Although the prevalence of this polymorphism is low, cattle carrying the K211 allele may be predisposed to rapid onset of BSE-H when exposed or to the potential development of a genetic BSE. This study was conducted to better understand the relationship between the K211 polymorphism and its effect on BSE phenotype. BSE-H from the US 2006 case was inoculated intracranially (IC) in one PRNP wild-type (EE211) calf and one EK211 calf. In addition, one wild-type calf and one EK211 calf were inoculated IC with brain homogenate from a US 2003 classical BSE case. All cattle developed clinical disease. The survival time of the E211K BSE-H inoculated EK211 calf (10 months) was shorter than the wild-type calf (18 months). This genotype effect was not observed in classical BSE inoculated cattle (both 26 months). Significant changes in retinal function were observed in H-type BSE challenged cattle only. Cattle challenged with the same inoculum showed similar severity and neuroanatomical distribution of vacuolation and disease-associated prion protein deposition in the brain, though differences in neuropathology were observed between E211K BSE-H and classical BSE inoculated animals. Western blot results for brain tissue from challenged animals were consistent with the inoculum strains. This study demonstrates that the phenotype of E211K BSE-H remains stable when transmitted to cattle without the K211 polymorphism, and exhibits a number of features that differ from classical BSE in both wild-type and heterozygous EK211 animals. PMID- 27695696 TI - Antimicrobial Susceptibility Patterns of Environmental Streptococci Recovered from Bovine Milk Samples in the Maritime Provinces of Canada. AB - Determination of antimicrobial susceptibility of bovine mastitis pathogens is important for guiding antimicrobial treatment decisions and for the detection of emerging resistance. Environmental streptococci are ubiquitous in the farm environment and are a frequent cause of mastitis in dairy cows. The aim of the study was to determine patterns of antimicrobial susceptibility among species of environmental streptococci isolated from dairy cows in the Maritime Provinces of Canada. The collection consisted of 192 isolates identified in milk samples collected from 177 cows originating from 18 dairy herds. Results were aggregated into: (1) Streptococcus uberis (n = 70), (2) Streptococcus dysgalactiae (n = 28), (3) other Streptococci spp. (n = 35), (4), Lactococcus spp. (n = 32), and (5) Enterococcus spp. (n = 27). Minimum inhibitory concentrations (MICs) were determined using the Sensititre microdilution system and mastitis plate format. Multilevel logistic regression models were used to analyze the data, with antimicrobial susceptibility as the outcome. The proportion of susceptible S. uberis ranged from 23% (for penicillin) to 99% (for penicillin/novobiocin), with a median of 82%. All S. dysgalactiae were susceptible to all antimicrobials except for penicillin (93% susceptible) and tetracycline (18% susceptible). The range of susceptibility for other Streptococcus spp. was 43% (for tetracycline) to 100%, with a median percent susceptibility of 92%. Lactococcus spp. isolates displayed percent susceptibilities ranging from 0% (for penicillin) to 97% (for erythromycin), median 75%. For the antimicrobials tested, the minimum inhibitory concentrations were higher for Enterococcus spp. than for the other species. According to the multilevel models, there was a significant interaction between antimicrobial and bacterial species, indicating that susceptibility against a particular antimicrobial varied among the species of environmental streptococci and vice versa. Generally, susceptibility decreased with increasing within-herd average somatic cell count, isolates recovered in mid-lactation were more susceptible than isolates recovered in early lactation, and isolates recovered in samples collected post-clinical mastitis were more susceptible than isolates recovered from non-clinical lactating quarters. The results of this research support continued susceptibility of environmental streptococci to beta-lactam antimicrobials. A departure from the expected susceptibility to beta-lactams was the apparent reduced susceptibility of S. uberis to penicillin. PMID- 27695697 TI - A Novel Model for Acute Peripheral Nerve Injury in the Horse and Evaluation of the Effect of Mesenchymal Stromal Cells Applied In Situ on Nerve Regeneration: A Preliminary Study. AB - Transplantation of mesenchymal stromal cells (MSCs) to sites of experimentally created nerve injury in laboratory animals has shown promising results in restoring nerve function. This approach for nerve regeneration has not been reported in horses. In this study, we first evaluated the in vitro ability of equine bone marrow-derived MSCs (EBM-MSCs) to trans-differentiate into Schwann like cells and subsequently tested the MSCs in vivo for their potential to regenerate a transected nerve after implantation. The EBM-MSCs from three equine donors were differentiated into SCLs for 7 days, in vitro, in the presence of specialized differentiation medium and evaluated for morphological characteristics, by using confocal microscopy, and for protein characteristics, by using selected Schwann cell markers (GFAP and S100b). The EBM-MSCs were then implanted into the fascia surrounding the ramus communicans of one fore limb of three healthy horses after a portion of this nerve was excised. The excised portion of the nerve was examined histologically at the time of transection, and stumps of the nerve were examined histologically at day 45 after transplantation. The EBM-MSCs from all donors demonstrated morphological and protein characteristics of those of Schwann cells 7 days after differentiation. Nerves implanted with EBM-MSCs after nerve transection did not show evidence of nerve regeneration at day 45. Examination of peripheral nerves collected 45 days after injury and stem cell treatment revealed no histological differences between nerves treated with MSCs and those treated with isotonic saline solution (controls). The optimal delivery of MSCs and the model suitable to study the efficacy of MSCs in nerve regeneration should be investigated. PMID- 27695698 TI - A Prospective, Randomized, Masked, and Placebo-Controlled Efficacy Study of Intraarticular Allogeneic Adipose Stem Cells for the Treatment of Osteoarthritis in Dogs. AB - Osteoarthritis (OA) is a degenerative joint disease with a high prevalence in dogs. Mesenchymal stem cells (MSCs) have been used to treat humans, dogs, and horses with OA. This report describes a prospective, randomized, blinded, and placebo-controlled clinical efficacy study of intraarticular allogeneic adipose stem cells for the treatment of dogs with OA. Health assessments and measurements of pain and activity impairment were performed at baseline and at selected time points through day 60. The primary outcome variable was the owner Client-Specific Outcome Measurement (CSOM) and secondary measures included veterinary pain on manipulation, veterinary global score, and owner global score. The dogs were treated with either a saline placebo or a single dose of allogeneic adipose derived MSCs in either one or two joints. Seventy-four dogs were statistically analyzed for efficacy outcomes. Success in the primary outcome variable, CSOM, was statistically improved in the treated dogs compared to the placebo dogs (79.2 versus 55.4%, p = 0.029). The veterinary pain on manipulation score (92.8 versus 50.2%, p = 0.017) and the veterinary global score (86.9 versus 30.8%, p = 0.009) were both statistically improved in treated dogs compared to placebo. There was no detected significant difference between treated and placebo dogs in the incidence of adverse events or negative health findings. Allogeneic adipose derived stem cell treatment was shown to be efficacious compared to placebo. This large study of dogs also provides valuable animal clinical safety and efficacy outcome data to our colleagues developing human stem cell therapy. PMID- 27695699 TI - Reduction of Salmonella Typhimurium by Fermentation Metabolites of Diamond V Original XPC in an In Vitro Anaerobic Mixed Chicken Cecal Culture. AB - Fermentation metabolites of Diamond V Original XPCTM (XPC), a biological product derived from yeast fermentation, were evaluated for their ability to reduce the Salmonella Typhimurium population using an in vitro mixed anaerobic culture system containing cecal microbiota to simulate chicken hindgut conditions. Four different samples were prepared: anaerobic mixed culture containing (1) feed only, (2) cecal only (ceca were harvested from 42 days old broiler chickens), (3) feed and cecal contents, and (4) feed, cecal contents, and 1% XPC. Two experimental conditions were investigated: Group 1, in which the cecal content was added at the same time as a S. Typhimurium marker strain and Group 2, in which the cecal content was preincubated for 24 h prior to the inoculation with the S. Typhimurium marker strain. The mixed cultures were incubated anaerobically at 37 degrees C, and the S. Typhimurium marker strain was enumerated at 0, 24, and 48 h. Analysis of short chain fatty acids was also conducted for 24 h. In the Group 1 experiment, adding XPC did not exhibit significant reduction of S. Typhimurium. However, the presence of XPC resulted in rapid reduction of S. Typhimurium in Group 2. S. Typhimurium was reduced from 6.81 log10 CFU/ml (0 h) to 3.73 log10 CFU/ml and 1.19 log10 CFU/ml after 24 and 48 h, respectively. These levels were also 2.47 log10 and 2.72 log10 lower than the S. Typhimurium level recovered from the control culture with feed and cecal contents, but without XPC. Based on these results, it appears that the ability of XPC to reduce S. Typhimurium requires the presence of the cecal microbiota. Short chain fatty acid analysis indicated that acetate and butyrate concentrations of cultures containing XPC were twofold greater than the control cultures by 24 h of anaerobic growth. Results from the present study suggest that dietary inclusion of XPC may influence cecal microbiota fermentation and has the potential to reduce Salmonella in the cecum. Implications of these findings suggest that XPC may decrease preharvest levels of Salmonella in broilers and layers. PMID- 27695701 TI - What Clinical Interventions Have Been Implemented to Prevent or Reduce Postpartum Hypertension Readmissions? A Clin-IQ. AB - A literature review was conducted to determine what clinical interventions have been studied and implemented to prevent and/or reduce postpartum hypertension readmissions. Appropriate verbal and printed educational materials should be given to the patient prior to discharge with use of the "teach back" method. Patients and health care providers within the multidisciplinary team should be educated on the warning signs and symptoms of worsening hypertensive disease and when to appropriately involve the obstetrician. The use of text messaging may be useful in preventing hospital readmissions by increasing patient follow-up and compliance and appropriately managing patients in the postpartum period. Treating postpartum patients with furosemide may decrease blood pressure and prevent postpartum hypertension and the need for antihypertensive therapy. PMID- 27695702 TI - Microfluidic-based Time-kill Kinetic Assay. AB - In many environments, bacteria favor a sessile, surface-attached community lifestyle. These communities, termed biofilms, are ubiquitous among many species of bacteria. In some cases, biofilms form under flow conditions. Flow chambers, and in particular microfluidic channels, can be used to observe biofilm development and physiological effects while varying nutrient conditions, flow velocities, or introducing antimicrobials to the biofilm in real time. Here, we describe a microfluidic-based kill-kinetics assay for the observation of antimicrobial effects on biofilms under flowing conditions. PMID- 27695700 TI - Regulatory Networks that Direct the Development of Specialized Cell Types in the Drosophila Heart. AB - The Drosophila cardiac tube was once thought to be a simple linear structure, however research over the past 15 years has revealed significant cellular and molecular complexity to this organ. Prior reviews have focused upon the gene regulatory networks responsible for the specification of the cardiac field and the activation of cardiac muscle structural genes. Here we focus upon highlighting the existence, function, and development of unique cell types within the dorsal vessel, and discuss their correspondence to analogous structures in the vertebrate heart. PMID- 27695703 TI - Gene Mutations Associated with Temporomandibular Joint Disorders: A Systematic Review. AB - BACKGROUND: The temporomandibular joint (TMJ) is a bilateral synovial joint between the mandible and the temporal bone of the skull. TMJ disorders (TMDs) are a set of complicated and poorly understood clinical conditions, in which TMDs are associated with a number of symptoms including pain and limited jaw movement. The increasing scientific evidence suggests that genetic factors play a significant role in the pathology of TMDs. However, the underlying mechanism of TMDs remains largely unknown. OBJECTIVE: The study aimed to determine the associated genes to TMDs in humans and animals. METHODS: The literature search was conducted through databases including Medline (Ovid), EMBASE (Ovid), and PubMed (NLM) by using scientific terms for TMDs and genetics in March 2015. Additional studies were identified by searching bibliographies of highly relevant articles and Scopus (Elsevier). RESULTS: Our systematic analyses identified 31 articles through literature searches. A total of 112 genes were identified to be significantly and specifically associated with TMDs. CONCLUSION: Our systematic review provides a list of accurate genes associated with TMDs and suggests a genetic contribution to the pathology of TMDs. PMID- 27695704 TI - Cognitive neuroscience of honesty and deception: A signaling framework. AB - Understanding the neural basis of human honesty and deception has enormous potential scientific and practical value. However, past approaches, largely developed out of studies with forensic applications in mind, are increasingly recognized as having serious methodological and conceptual shortcomings. Here we propose to address these challenges by drawing on so-called signaling games widely used in game theory and ethology to study behavioral and evolutionary consequences of information transmission and distortion. In particular, by separating and capturing distinct adaptive problems facing signal senders and receivers, signaling games provide a framework to organize the complex set of cognitive processes associated with honest and deceptive behavior. Furthermore, this framework provides novel insights into feasibility and practical challenges of neuroimaging-based lie detection. PMID- 27695705 TI - Predictive coding of multisensory timing. AB - The sense of time is foundational for perception and action, yet it frequently departs significantly from physical time. In the paper we review recent progress on temporal contextual effects, multisensory temporal integration, temporal recalibration, and related computational models. We suggest that subjective time arises from minimizing prediction errors and adaptive recalibration, which can be unified in the framework of predictive coding, a framework rooted in Helmholtz's 'perception as inference'. PMID- 27695706 TI - Community violence concerns and adolescent sleep. AB - OBJECTIVE: The goal of this study was to examine links between concerns about community violence and objective and subjective sleep parameters in an adolescent sample. Sex was considered as a moderator of effects. DESIGN: The study used a cross-sectional design. PARTICIPANTS: The community-based sample included 252 adolescents (53% girls) with an average age of 15.79 years (SD = 0.81) from the Southeastern United States. The sample included 34% African American and 66% European American adolescents from a wide range of socioeconomic backgrounds. MEASUREMENTS: Adolescent-reported community violence concerns were assessed using a composite of 3 separate subscales that measured perceived community safety and threats of community and school violence. Sleep duration and quality were assessed using actigraphy, and subjective sleep problems and daytime sleepiness were measured with subscales of the School Sleep Habits Survey. RESULTS: Community violence predicted lower sleep efficiency, more long-wake episodes, and more sleep/wake problems and sleepiness. Sex-related moderation effects revealed that girls in the sample were more vulnerable to the effects of violence concerns on their objective sleep quality. CONCLUSIONS: Findings highlight the role of community violence concerns on adolescents' sleep, revealing that greater community violence concerns are linked with lower levels of actigraphy-based and subjective reports of sleep quality, particularly for adolescent girls. Consideration of the mechanisms by which violence concerns may affect sleep is discussed. PMID- 27695707 TI - Using baseline cognitive severity for enriching Alzheimer's disease clinical trials: How does Mini-Mental State Examination predict rate of change? AB - BACKGROUND: Post hoc analyses from clinical trials in Alzheimer's disease suggest more cognitively impaired participants respond differently from less impaired on cognitive outcomes. We examined pooled clinical trials data to assess the utility of enriching trials using baseline cognition. METHODS: We included 2,882 participants with mild to moderate AD in 7 studies from a meta-database. We used mixed effects models to estimate rate of decline in ADAS-cog scores among MMSE groups. FINDINGS: Baseline MMSE category was associated with baseline scores and rate of decline on the ADAS-cog, adjusting for age and education (both p<0.001). Greater baseline cognitive impairment was associated with more rapid progression. INTERPRETATIONS: Although we found significant differences in rate of decline, the majority of differences between individuals were from baseline ADAS-cog values. Enrichment based on MMSE would reduce the recruitment pool while adding only slightly to detecting differences in rate of progression and is not advised. PMID- 27695708 TI - Coordinated expression of tyro3, axl, and mer receptors in macrophage ontogeny. AB - The TAM receptors (Tyro3, Axl, and Mer) are a family of homologous receptor tyrosine kinases that inhibit Toll-like receptor signaling to regulate downstream pathways and restore homeostasis. TAM triple mutant mice (Tyro3-/-, Axl-/-, Mer-/ ) have elevated levels of pro-inflammatory cytokines and are prone to developing lymphoproliferative disorders and autoimmunity. Understanding differential expression of TAM receptors among human subjects is critical to harnessing this pathway for therapeutic interventions. We have quantified changes in TAM expression during the ontogeny of human macrophages using paired samples of monocytes and macrophages to take advantage of characteristic expression within an individual. No significant differences in levels of Tyro3 were found between monocytes and macrophages (flow cytometry: p=0.652, immunoblot: p=0.231, qPCR: p=0.389). Protein levels of Axl were reduced (flow cytometry: p=0.049, immunoblot: p<0.001) when monocytes matured to macrophages. No significant differences in the levels of Axl mRNA transcripts were found (qPCR: p=0.082), however, Tyro3 and Axl were proportionate. The most striking difference was upregulation of expression of Mer with both protein and mRNA being significantly increased when monocytes developed into macrophages (flow cytometry: p<0.001, immunoblot: p<0.001, qPCR: p=0.004). A fuller characterization of TAM receptor expression in macrophage ontogeny informs our understanding of their function and potential therapeutic interventions. PMID- 27695709 TI - Demonstration of an Inline Publication Image Viewer: The Future of Radiological Publishing. AB - Publications which present images containing multi-dimensional image content have traditionally been confined to present information in a static 2-dimensional format. Inclusion of videos within a publication provides enhanced opportunities to present multi-dimensional image views rather than relying on static images to communicate findings. However, asignificant advance is presented in which an image viewer in integrated into Tomography's digital publication format allowing foruser manipulated and interactive multi-dimensional viewing of published image data directly inline with the manuscript. This 'small step' in technological advancement allowing for user manipulation and interrogation of multidimensional published image datais a 'giant leap' forward for publishing in the field of radiological sciences and beyond. PMID- 27695710 TI - A Structural Equation Model of HIV-related Symptoms, Depressive Symptoms, and Medication Adherence. AB - Adherence to combined antiretroviral therapy (cART) remains critical in management of HIV infection. This study evaluated depression as a potential mechanism by which HIV-related symptoms affect medication adherence and explored if particular clusters of HIV symptoms are susceptible to this mechanism. Baseline data from a multi-visit intervention study were analyzed among 124 persons living with HIV (PLWH). A bifactor model showed two clusters of HIV related symptom distress: general HIV-related symptoms and gastrointestinal (GI) symptoms. Structural equation modeling showed that both general HIV-related symptoms and GI symptoms were related to higher levels of depressive symptoms, and higher levels of depressive symptoms were related to lower levels of medication adherence. Although general HIV-related symptoms and GI symptoms were not directly related to adherence, they were indirectly associated with adherence via depression. The findings highlight the importance of early recognition and evaluation of symptoms of depression, as well as the underlying physical symptoms that might cause depression, to improve medication adherence. PMID- 27695711 TI - Effect of National Schistosomiasis Control Programme on Taenia solium taeniosis and porcine cysticercosis in rural communities of Tanzania. AB - Taenia solium is found throughout sub-Saharan Africa and co-endemic with schistosomiasis in many regions. Taenia solium leads to taeniosis and neurocysticercosis - the leading cause of preventable epilepsy globally. This study aimed to assess the effects of the National Schistosomiasis Control Programme on prevalence of taeniosis and porcine cysticercosis over a four year period in Tanzania. School-based mass drug administration (MDA) of praziquantel was carried out based on schistosomiasis endemicity. Four human and five porcine cross-sectional surveys were carried out from 2012 to 2015 in Mbozi and Mbeya district in Tanzania. Three rounds of school-based MDA of praziquantel were delivered in Mbozi and two in Mbeya. The prevalence of taeniosis and porcine cysticercosis was estimated annually. Stool samples were collected from humans and prevalence of taeniosis estimated by copro-Ag-ELISA. Blood samples from pigs were collected to estimate cysticercosis prevalence by Ag-ELISA. "Track-and treat" of taeniosis cases was carried out after each survey. In total 12082 stool samples and 4579 porcine serum samples were collected. Significantly fewer children (<= 15) from Mbozi were infected throughout the study than children from Mbeya who showed a significant decrease in copro-Ag prevalence after the first treatment only. During the final survey in Mbozi the prevalence of taeniosis in adults (1.8%) was significantly lower (p = 0.031, OR 0.40, CI: 0.17-0.89), compared to baseline (4.1%). The prevalence of porcine cysticercosis (8%) had also dropped significantly (p = 0.002, OR 0.49, CI: 0.32-0.76) in this district compared to baseline (13%), whereas no significant difference was seen in Mbeya compared to baseline. The study suggests that three rounds of MDA targeting schistosomiasis in school-aged children combined with 'track-and-treat' contributed to a reduction in prevalence of T. solium in this population, and also had a spillover effect on adults in treated areas as well as reducing the prevalence of T. solium in the intermediate pig host population. Elimination of T. solium in this area would require a One Health approach. PMID- 27695712 TI - RNA Editing Dynamically Rewrites the Cancer Code. AB - Global analyses of cancer transcriptomes demonstrate that ADAR (adenosine deaminase, RNA-specific)-mediated RNA editing dynamically contributes to genetic alterations in cancer, and directly correlates with progression and prognosis. RNA editing is abundant and frequently elevated in cancer, and affects functionally and clinically relevant sites in both coding and non-coding regions of the transcriptome. Therefore, ADAR and differentially edited transcripts may be promising biomarkers or targets for therapy. PMID- 27695713 TI - Intracoronary Poloxamer 188 Prevents Reperfusion Injury in a Porcine Model of ST Segment Elevation Myocardial Infarction. AB - BACKGROUND: Poloxamer 188 (P188) is a nonionic triblock copolymer believed to prevent cellular injury after ischemia and reperfusion. OBJECTIVES: This study compared intracoronary infusion of P188 immediately after reperfusion with delayed infusion through a peripheral intravenous catheter in a porcine model of ST segment elevation myocardial infarction (STEMI). Cellular and mitochondrial injury were assessed. METHODS: STEMI was induced in 55 pigs using 45 minutes of endovascular coronary artery occlusion. Pigs were then randomized to four groups: control, immediate intracoronary (IC) P188, delayed peripheral P188, and polyethylene glycol (PEG) infusion. Heart tissue was collected after 4 hours of reperfusion. Assessment of mitochondrial function or infarct size was performed. RESULTS: Mitochondrial yield improved significantly with IC P188 treatment compared to control animals (0.25% vs. 0.13%) suggesting improved mitochondrial morphology and survival. Mitochondrial respiration and calcium retention were also significantly improved with immediate IC P188 compared to controls (complex I RCI: 7.4 vs. 3.7 and calcium retention (nmol): 1152 vs. 386). This benefit was only observed with activation of complex I of the mitochondrial respiratory chain suggesting a specific impact of ischemia and reperfusion on this complex. Infarct size and serum troponin I were significantly reduced by immediate IC P188 infusion (infarct size: 13.9% vs. 41.1% and troponin I (MUg/L): 19.2 vs. 77.4 MUg/L). Delayed P188 and PEG infusion did not provide a significant benefit. CONCLUSIONS: Intracoronary infusion of P188 immediately upon reperfusion significantly reduces cellular and mitochondrial injury after ischemia and reperfusion in this clinically relevant porcine model of STEMI. The timing and route of delivery were critical to achieve the benefit. PMID- 27695714 TI - Silorane-based Composite Resin Restorations Are Not Better than Conventional Composites - A Meta-Analysis of Clinical Studies. AB - PURPOSE: To perform a systematic review of the clinical performance of a low polymerization shrinkage, siloranebased composite (SBC) compared with a methacrylate-based composite (MBC) in posterior restorations. MATERIALS AND METHODS: Electronic databases were searched: PubMed, Scopus, Bireme, Science Direct, Web of Science, ClinicalTrials.gov and OpenGrey. The search strategy included MeSH terms, synonyms and keywords with no language or date restrictions. Reference lists of eligible studies were cross checked in an attempt to identify additional studies. Based on the PICOS strategy, only randomized clinical trials (RCTs) were included. The risk of bias in the included studies was assessed and classified through the Cochrane Collaboration common scheme for bias. Two meta analyses were performed using RevMan software, one with all 11 studies and another that included only studies with over 24 months of follow-up, for the main parameters analyzed. RESULTS: A total of 544 studies were identified. After removing duplicates and examinating titles and abstracts, 17 texts were selected and read in full. Six of them were excluded, so the final sample of this systematic review included 11 studies. Six of the 11 studies were classified as having a "low risk of bias" and five were "unclear". The heterogeneity (I2) in all parameters was not significant. The exclusion of studies with less than 24 months of follow- up did not change the final result of the meta-analysis: both SBC and MBC have satisfactory and statistically similar clinical performances. CONCLUSION: Low polymerization shrinkage is not the principal factor that determines the superiority of a resin.

AB - PURPOSE: To evaluate the suitability of an ultra-short pulsed laser (USPL) to treat zirconia ceramic surfaces and increase their adhesion to dual-curing resin cement. MATERIALS AND METHODS: Twenty 10 * 10 * 5 mm3 blocks were prepared from a zirconia ceramic (Y-TZP). The specimens were polished and randomly assigned to four groups (n = 5) which received the following surface treatments: sandblasting (SB) with Al2O3 particles and silica coating (SC) with SiO2 particles as positive controls; two groups received USPL irradiation, one with 10 scan repetitions (L10) and the other with 20 (L20). Laser irradiation was performed at 1030 nm, 2.3 J/cm2, 6 ps pulse duration. The ceramic blocks were duplicated in composite resin and cemented with a dual-curing resin cement. Half of the blocks were then stored in water (37 degrees C) for 24 h and the other half for 1 month. At each time, 40 to 60 sticks per group were subjected to microtensile bond strength testing. Data were analyzed statistically using the Kruskal-Wallis test (alpha = 0.05). RESULTS: Laser-treated zirconia presented statistically significantly higher roughness than did SB and SC. After 24 h, the highest bond strength means (MPa) were achieved by L10 (42.3 +/- 10.8) and L20 (37.9 +/- 14.4), and both of them were statistically significantly higher than SB (22.0 +/- 5.3) and SC (20.8 +/- 7.1) (p < 0.05). After 1 month of storage, L10- and L20-treated zirconia still showed significantly higher bond strengths than did SB- and SC-treated zirconia (p < 0.05). CONCLUSION: USPL irradiation significantly increases bond strength of zirconia ceramic to dual-curing resin cement and might be an alternative for improving adhesion to this material. PMID- 27695715 TI - Which Factors Influence the Shear Bond Strength of Sealant Materials? AB - PURPOSE: This study investigated the influence of several methodological details on the shear bond strength (SBS) testing of pit and fissure sealants. The following variables were considered: type of enamel surfaces, prismatic vs aprismatic enamel, etching time, and aging and shearing procedures. MATERIALS AND METHODS: The surfaces of 180 healthy human third molars were divided into 4 different sections (mesial, distal, buccal, and oral). After tooth separation, the specimens were randomly allocated to the following groups: 1) enamel preparation: prismatic vs aprismatic; 2) etching: 30 s vs 60 s; 3) aging: 1 day or 3 months vs 5000 thermocycles; 4) shearing: notched-edge method (ISO 29022:2013) vs knife-edge method. After following each protocol, SBS was determined using a universal testing machine, followed by failure mode analysis. Data were analysed using Mann-Whitney U-tests and regression analyses. RESULTS: In the aprismatic enamel group, the longer etching time resulted in slightly, not statistically significantly higher SBS. When aging sealants on aprismatic enamel with different procedures, significantly lower SBS was found for 5000 thermocycles. In the case of aprismatic enamel etched for 60 s and sheared with the notched-edge blade, there was no significant difference between the aging procedures. Failure mode analysis showed adhesive failures to be predominant. Simple linear regression revealed that all of the included factors significantly influenced SBS. In a multiple linear regression model, the variables "aprismatic enamel" and "distal surface" were associated with a higher SBS; "5000 thermocycles" reduced SBS significantly. CONCLUSION: Enamel grinding, aging method, and type of enamel surface significantly influenced the SBS. PMID- 27695717 TI - An analysis of general practice encounters by socioeconomic disadvantage. PMID- 27695718 TI - Meeting the primary care needs ?of young people in residential care. AB - BACKGROUND: Young people in out-of-home care, especially those with a history of multiple placements, typically have numerous and complex health needs, and worse health outcomes than their peers who grow up within a family of origin. A significant proportion of this can be attributed to policy failures and poor interagency communication. OBJECTIVE: The objective of this article is to describe the factors that contribute to the health needs of young people in out of-home care and the tools available to support general practitioners (GPs) to provide care. DISCUSSION: GPs are crucial in the early detection of health problems and intervention for this vulnerable population. Marked social and relational problems make the high-priority task of creating a safe and trusting environment a challenge. GPs must also work within the statutory requirements of each state and territory, and navigate the complex out-of-home care system. Using recommended frameworks and maintaining effective communication and support will improve outcomes for these young people, their families and the community. PMID- 27695719 TI - Teenage mothers. AB - BACKGROUND: Australia's teenage birth rate has fallen to historic lows, but teenage motherhood still occurs and can be challenging for mother and baby. OBJECTIVE: The aim of this article is to review current evidence on the epidemiology and clinical care of teenage pregnancy and parenting, and provide recommendations around management of these young people in Australia. DISCUSSION: Teenage mothers may have experienced family, sexual, and partner violence, family disruption, and socioeconomic disadvantage. Outcomes on a range of peripartum measures are worse for teenage mothers and their babies. Longer term risks for the mother include depression and rapid repeat pregnancy; for the child, intergenerational teenage parenthood; and for both, socioeconomic disadvantage. Teenage motherhood occurs more often within communities where poverty, Aboriginal and Torres Strait Islander status and rural/remote location intersect. General practitioners play a critical role in identification of at-risk teens, preventing unintended teenage pregnancy, clinical care of pregnant teens, and promoting the health and wellbeing of teenage mothers and their children. PMID- 27695720 TI - A practical overview of the treatment ?of chronic hepatitis C virus infection. AB - BACKGROUND: Although hepatitis C virus (HCV) infection is associated with significant morbidity and mortality, OBJECTIVE: This article provides an overview for GPs on the principles involved in assessing and treating patients with chronic hepatitis C within a community setting. DISCUSSION: Treatment with DAA medications listed on the PBS should be considered for all patients with chronic HCV infection. These regimens are well tolerated, highly efficacious and have all oral administration. A thorough pre-treatment evaluation should be undertaken, and patients with cirrhosis, significant comorbidities or potential drug-drug interactions should be referred to a specialist. Successful eradication of HCV is characterised by undetectable HCV ribonucleic acid viral load on polymerase chain reaction testing 12 weeks after treatment completion, although antibodies to HCV may remain positive for the rest of the patient's life. PMID- 27695721 TI - Uterine fibroids: Investigation ?and current management trends. AB - BACKGROUND: Uterine leiomyomas, or fibroids, represent a large proportion of gynaecological presentations in both general and specialist gynaecology practice. The diagnosis is relatively simple with current imaging modalities. The management of fibroids, however, is not always straightforward and can present many challenges. OBJECTIVE: This article reviews current approaches to the management of uterine fibroids, including novel techniques, and highlights important patient counselling points. DISCUSSION: Many fibroids cause debilitating symptoms that greatly affect a woman's quality of life. Traditional surgical treatment options include myomectomy and hysterectomy. Minimally invasive surgical and radiological techniques, as well as symptomatic treatment, including the use of hormonal medication, intrauterine devices, and endometrial ablation, have become increasingly popular treatment choices. While these treatments are associated with reduced perioperative morbidity and shorter hospital stays, patients should be carefully counselled regarding the risks and the benefits. General practitioners may often help to initiate discussions to assist women considering their management options.

PMID- 27695723 TI - 'If they're your doctor, they should care about you': Women on release from prison and general practitioners. AB - BACKGROUND: Nearly half of the people leaving prison see a general practitioner (GP) within a month of release, which provides an opportunity to promote health for this vulnerable group. OBJECTIVE: The objective of this article is to examine the expectations and experiences of GP care of women leaving prison. METHODS: Semi-structured interviews pre-release and post-release from prison were analysed using inductive thematic analysis. RESULTS: Sixty-nine interviews were conducted with 40 women while they were still in prison and 29 of these women after they were released. Women perceived GPs as lacking interest in their social support needs and believed GPs needed more skills in substance misuse management. Given the fear of stigma, women may not disclose recent incarceration, affecting the continuity of healthcare initiated in prison. DISCUSSION: GPs' acknowledgement of, and assistance with, the broad issues that have an impact on the health and wellbeing of women after release is valued. Whole-person care also requires GP accessibility, management of substance misuse, continuity of care and understanding of the stigma associated with incarceration. PMID- 27695724 TI - Australian women's experiences of the subdermal contraceptive implant: A qualitative perspective. AB - BACKGROUND: The number of prescriptions for contraceptive implants has steadily increased in Australia, but implant use is still low. OBJECTIVE: The objectives of the study were to describe women's nuanced responses, and characterise their multidimensional and complex reasons for (dis)continuing use of the contraceptive implant. METHODS: A descriptive qualitative approach was used for this study. A larger qualitative study using in-depth, open-ended interviews, conducted in New South Wales between 2012 and 2013 with 94 women aged 16-49 years who had used contraception, included 10 interviews containing accounts of implant use. The 10 interviews were analysed thematically in the present study. RESULTS: The three main themes analysed from the 10 interviews were perceived benefits, undesirable experiences and perseverance. DISCUSSION: The participants were well informed about the benefits of the implant. Many persevered with it for a significant period of time before discontinuing it, despite experiencing side effects such as bleeding or mood changes. A decision to discontinue was often only made after an accumulation of multiple side effects. PMID- 27695725 TI - Patients' perspectives about why they have their contraceptive Implanon NXT device removed early. AB - BACKGROUND: Women with long-acting, reversible contraceptive devices inserted may choose to remove them prior to their planned expiry dates. OBJECTIVE: The objective of this study was to explore Australian women's experiences with the etonogestrel subdermal contraceptive implant (Implanon NXT) and why they had it removed early. METHODS: Semi-structured interviews were conducted with 18 women between June 2013 and January 2014. Transcriptions of the audio-taped interviews were analysed using a constant comparative analysis framework. RESULTS: Two core themes of participants' responses that were identified in this study were influences on choice of contraception, which included convenience and information sources; and influences on removal of contraception, which included side effects and their negative impacts on relationships and financial costs. DISCUSSION: This study highlights that women's experiences with side effects contribute to the early removal of long-acting contraceptive devices such as Implanon NXT. This study emphasises the importance of general practitioners (GPs) in providing comprehensive information about the benefits and potential side effects associated with using these implants. PMID- 27695726 TI - General practitioner perspectives on referrals to paediatric public specialty clinics. AB - BACKGROUND: Changes in the demography of Australia have resulted in changes in patterns of primary care delivery. One of these changes is that the proportion of paediatric visits has decreased. OBJECTIVE: The objectives of the article are to examine patient, practice and personal factors that influence a general practitioner's (GP's) decision to refer patients for paediatric specialty care, and investigate referral goals and experience with shared care. METHODS: A mail survey was sent out to 400 GPs who had referred at least two children to public hospital specialty clinics during 2014. RESULTS: The response rate for the mail survey was 67%. The factors most commonly reported by GPs as 'Somewhat important' or 'Very important' in the decision to refer were whether they had enough knowledge of a specific condition (81%) or did not have experience with similar patients (75%). About one-quarter (26%) of GPs reported that a parental request 'Frequently' or 'Almost always' influenced their referral decision. A similar pro portion (26%) placed importance on whether they had sufficient time for a specific patient. DISCUSSION: Understanding the perspectives and determinants of GP referrals for paediatric specialty care is important, especially in the context of changing patterns of primary care delivery. PMID- 27695727 TI - Urban general practice and medical education: Academic outcomes from a unique urban, longitudinal integrated community-based program. AB - BACKGROUND: In 2009, Flinders University established an urban, community-based, longitudinal integrated program providing medical students extended placements that offered continuities of patient care, clinical supervision and peer group. OBJECTIVE: The aim of this research was to analyse academic outcomes of the new placement program. METHODS: The results of all students undertaking Year 3 exams from 2011 to 2014 were collected and analysed. The Years 1 and 2 exam results for students in the new program were also analysed. RESULTS: Students in the new placement program achieved significantly higher grades than those who undertook the traditional rotations program, with aver-age scores of 69.05, compared with 66.45 (P = 0.03). Analysis of average class ranking for students who undertook the new program showed a statistically significant improvement from 59th in class to 48th in class (P = 0.03). DISCUSSION: This evaluation shows that an urban, community-based, longitudinal integrated clerkship centred in general practice provides at least academically equivalent outcomes to traditional rotations-based programs. PMID- 27695728 TI - The medical home: A need for collaborative practice. PMID- 27695730 TI - Alcohol screening and brief interventions in primary care - Evidence and a pragmatic practice-based approach. AB - BACKGROUND: Risky alcohol drinking is a common problem in adults presenting in Australian general practice. Preventive health guidelines recommend routine delivery of alcohol screening and brief intervention (ASBI) by general practitioners (GPs). However, ASBIs have rarely been implemented successfully in a sustainable manner. OBJECTIVE: In this article, we explain the current state of empirical evidence for the effectiveness of ASBI in primary care and describe a pragmatic interpretation of how this evidence applies to routine care. DISCUSSION: The empirical evidence surrounding ASBIs is complex. ASBIs are efficacious in research settings, but their effectiveness when compared with control interventions in real-world practice is less certain. Alcohol assessment within therapeutic doctor-patient relationships, rather than the specific formal tools, may be the 'active ingredient'. A pragmatic, practice-based approach to early detection of risky drinking is to focus on strategies that allow asking patients about their drinking more regularly, documenting it, and using quality improvement methodology to improve alcohol recording data completeness for the practice population. PMID- 27695729 TI - The evolving role of cardiac magnetic resonance imaging in the assessment of cardiovascular disease. AB - BACKGROUND: Imaging of the heart is important in the diagnosis and follow-up of a broad range of cardiac pathology. The authors discuss the growing role of cardiac magnetic resonance imaging (CMR) in cardiology practice and its relevance to primary healthcare. OBJECTIVE: In this article we discuss the advantages of CMR over other imaging modalities, and give a brief description of the common CMR techniques and cardiac pathologies where CMR is especially useful. DISCUSSION: CMR provides specific advantages over other cardiac imaging modalities when evaluating pathology in congenital heart disease, cardiac masses, cardiomyopathies, and in some aspects of ischaemic and valvular heart diseases. The strength of CMR in these pathologies includes its precise ana-tomical delineation of structures, characterisation of myocardial tissue, and accurate, reproducible measurements of blood volume and flow. CMR is used in inpatient and outpatient settings, and is available primarily in major hospitals. PMID- 27695735 TI - An Integrated Landscape Designed for Commodity and Bioenergy Crops for a Tile Drained Agricultural Watershed. AB - Locating bioenergy crops on strategically selected subfield areas of marginal interest for commodity agriculture can increase environmental sustainability. Location and choice of bioenergy crops should improve environmental benefits with minimal disruption of current food production systems. We identified subfield soils of a tile-drained agricultural watershed as marginal if they had areas of low crop productivity index (CPI), were susceptible to nitrate-nitrogen (NO-N) leaching, or were susceptible to at least two other forms of environmental degradation (marginal areas). In the test watershed (Indian Creek watershed, IL) with annual precipitation of 852 mm, 3% of soils were CPI areas and 22% were marginal areas. The Soil and Water Assessment Tool was used to forecast the impact of growing switchgrass ( L.), willow ( spp.), and big bluestem ( Vitman) in these subfield areas on annual grain yields, NO-N and sediment exports, and water yield. Simulated conversion of CPI areas from current land use to bioenergy crops had no significant ( 0.05) impact on grain production and reduced NO-N and sediment exports by 5.0 to 6.0% and 3.0%, respectively. Conversion of marginal areas from current land use to switchgrass forecasted the production of 34,000 t of biomass and reductions in NO-N (26.0%) and sediment (33.0%) exports. Alternatively, conversion of marginal areas from current land use to willow forecasted similar reductions as switchgrass for sediment but significantly ( 0.01) lower reductions in annual NO-N export (18.0 vs. 26.0%). PMID- 27695736 TI - Greenhouse Gas and Ammonia Emissions from Slurry Storage: Impacts of Temperature and Potential Mitigation through Covering (Pig Slurry) or Acidification (Cattle Slurry). AB - Storage of livestock slurries is a significant source of methane (CH) and ammonia (NH) emissions to the atmosphere, for which accurate quantification and potential mitigation methods are required. Methane and NH emissions were measured from pilot-scale cattle slurry (CS) and pig slurry (PS) stores under cool, temperate, and warm conditions (approximately 8, 11, and 17 degrees C, respectively) and including two potential mitigation practices: (i) a clay granule floating cover (PS) and (ii) slurry acidification (CS). Cumulative emissions of both gases were influenced by mean temperature over the storage period. Methane emissions from the control treatments over the 2-mo storage periods for the cool, temperate, and warm periods were 0.3, 0.1, and 34.3 g CH kg slurry volatile solids for CS and 4.4, 20.1, and 27.7 g CH kg slurry volatile solids for PS. Respective NH emissions for each period were 4, 7, and 12% of initial slurry N content for CS and 12, 18, and 28% of initial slurry N content for PS. Covering PS with clay granules reduced NH emissions by 77% across the three storage periods but had no impact on CH emissions. Acidification of CS reduced CH and NH emissions by 61 and 75%, respectively, across the three storage periods. Nitrous oxide emissions were also monitored but were insignificant. The development of approaches that take into account the influence of storage timing (temperature) and duration on emission estimates for national emission inventory purposes is recommended. PMID- 27695737 TI - Soil Aggregate Dynamics and Plant Community Response after Biosolids Application in a Semiarid Grassland. AB - Biosolids may improve the ecological function of degraded semiarid grasslands, but an understanding of the plant community is essential. An experiment was established in 2001 to determine the effects of a single surface application of biosolids on soil aggregate stability and the composition of the plant community in a semiarid grassland in British Columbia, Canada. Four treatments were evaluated: (i) surface biosolids application at 20 (Bio-20) and (ii) 60 Mg ha (Bio-60), (iii) mineral fertilizer, and (iv) a control. All treatments were replicated in four blocks. Soil was sampled during the spring (May), summer (June July), and fall (October) in 2005, 2006, and 2009; the plant community was assessed in 2009. The greatest increases in size of stable aggregates relative to the control were in the spring and summer, which coincided with a 1.6- to 2.1 fold increase in the spring concentration of N within stable aggregates when biosolids were applied at 20 and 60 Mg ha , respectively. Nitrogen concentrations from the Bio-60 treatment were not different from the control, but the Bio-20 treatment had 42% greater N than all other treatments during summer. Biosolids application in this ecosystem did not increase perennial forage grass species relative to the control, and when biosolids were applied at a rate of 60 Mg ha there was a 75% reduction in the perennial forage plant species. The application of biosolids to native grasslands in semiarid environments should be done cautiously, especially when winter annual plant species (e.g., cheatgrass [ L.]) are present before application. PMID- 27695738 TI - Comparison of Nutrient and Metal Loadings with the Application of Swine Manure Slurries and Their Liquid Separates to Soils. AB - The accumulation of phosphorus (P) and metals is a serious concern with the continuous application of manure to agricultural soils. Solid-liquid separation of swine slurry is a promising approach to reduce P and metal loadings through application of separated liquid (SL) as a nutrient source. However, little information is available on nutrient and metal loadings with the application of SL compared with unseparated raw manure (RM). We analyzed element concentrations and calculated nutrient and metal loadings for RM and their respective SL applications, considering an application rate of 100 kg total nitrogen (N) ha. Samples of SL were obtained through three separation techniques: (i) centrifugation without a flocculant, (ii) centrifugation with a flocculant, and (iii) rotary press with a flocculant. Irrespective of separation technique, calculated P loadings with the application of SL were only 50 to 70% of that of RM at equivalent rates of total N yet exceeded crop removal rate. In contrast, calculated K and Na loadings with SL application were significantly greater than with RM, indicating a possible build-up of K and Na in soil. Calculated Ca and Mg loadings were significantly greater with RM than with SL. Loadings of Al, As, Ba, Cd, Cr, Fe, Mn, Ni, Pb, Sn, Se, Ti, and V were low, whereas Cu and Zn loadings were above crop removal rates for RM and SL. For solid-liquid separation to provide a lasting solution to the problem of P and metal accumulation, the SL must be supplemented with commercial N fertilizer to meet crop N demand. PMID- 27695740 TI - Nitrogen Management for Corn and Groundwater Quality in Upper Midwest Irrigated Sands. AB - Groundwater contamination from NO-N leaching in corn ( L.) production with coarse textured soils poses an environmental concern. Our objectives were to evaluate NO N leaching in continuous corn (CC), corn after soybean ( L.) (CSb), and soybean after corn (SbC) in irrigated sandy soils in Minnesota related to (i) N rate using best management practices of split-N application, (ii) a split-N application and single preplant applications of enhanced-efficiency fertilizers (EEF), and (iii) residual N treatment in SbC. Urea (0-315 kg N ha in 45-kg increments) was broadcast as a split application (half at preplant and half at the V4 development stage) and polymer-coated urea (ESN), ESN/urea, and SuperU at preplant at a rate of 180 kg N ha on an Arvilla sandy loam soil. In May and June, 75% of the total drainage and 73% of the total NO-N leached occurred. At the economic optimum N rate (EONR), season-long NO-N leaching rates were 86 and 106 kg NO-N ha for CC and CSb, respectively. In CC, reducing the EONR by 20% reduced grain yield by 4% and NO-N leached by 9%, and a 25% reduction in EONR resulted in an additional 2% reduction for both, whereas no significant reductions occurred for CSb. Similar NO-N leaching occurred with EEFs and the split-N application. After 4 yr of no N application, we measured 9 to 20 mg NO-N L and leaching of 21 to 51 kg NO-N ha, highlighting the difficulty of meeting drinking water quality standards in corn cropping systems. PMID- 27695739 TI - Enabling Science Support for Better Decision-Making when Responding to Chemical Spills. AB - Chemical spills and accidents contaminate the environment and disrupt societies and economies around the globe. In the United States there were approximately 172,000 chemical spills that affected US waterbodies from 2004 to 2014. More than 8000 of these spills involved non-petroleum-related chemicals. Traditional emergency responses or incident command structures (ICSs) that respond to chemical spills require coordinated efforts by predominantly government personnel from multiple disciplines, including disaster management, public health, and environmental protection. However, the requirements of emergency response teams for science support might not be met within the traditional ICS. We describe the US ICS as an example of emergency-response approaches to chemical spills and provide examples in which external scientific support from research personnel benefitted the ICS emergency response, focusing primarily on nonpetroleum chemical spills. We then propose immediate, near-term, and long-term activities to support the response to chemical spills, focusing on nonpetroleum chemical spills. Further, we call for science support for spill prevention and near-term spill-incident response and identify longer-term research needs. The development of a formal mechanism for external science support of ICS from governmental and nongovernmental scientists would benefit rapid responders, advance incident- and crisis-response science, and aid society in coping with and recovering from chemical spills. PMID- 27695741 TI - Confirmation of the Impact of Onsite Wastewater Treatment Systems on Stream Base Flow Nitrogen Concentrations in Urban Watersheds of Metropolitan Atlanta, GA. AB - Wastewater and lawn fertilizer potentially contribute to degraded water quality in urban watersheds. Previously we described a study from 2011 to 2012 in which we examined the effect of the density of onsite wastewater treatment systems (OWTS) on nitrogen concentrations in 24 small streams in metropolitan Atlanta. Our objective in this study was to confirm that the impact on water quality that we observed was due to OWTS and not lawn fertilizer. We sampled the same 24 streams again in 2013 and 2014, representing watersheds ranging in area from 0.18 to 8.8 km. We conducted regression analysis of the effect of OWTS and season, used dual-isotope analysis (nitrogen and oxygen in nitrate) to identify sources and determine the effect of denitrification and mixing, and conducted stream walks to identify areas where animals had access to the streams. Twelve streams were characterized as high-density (HD, more than 75 systems km) OWTS and 12 as low-density (LD, less than 75 systems km) OWTS. Water samples were collected three times a year under base-flow conditions, from November 2011 to July 2014, and analyzed for nitrate (NO-N), ammonium (NH-N), and total Kjeldahl nitrogen. Total nitrogen and NO-N concentrations increased linearly with increasing OWTS density above a threshold of about 75 OWTS km. Dual-isotope analysis of NO showed that stream NO originated predominantly from OWTS in HD watersheds and from a combination of animal waste and perhaps organic N in LD watersheds. Stream walks showed that livestock had access to some of the LD streams with high N concentrations. Our results confirm that HD OWTS can significantly degrade water quality at the watershed scale. PMID- 27695743 TI - Copper and Zinc Runoff from Land Application of Composted Poultry Litter. AB - Regions with long-term animal manure applications based on nitrogen (N) requirements have concerns regarding elevated nutrient levels. Most attention has focused on phosphorus (P), but heavy metal accumulation has received attention due to perceived environmental concerns. Composting is a potential management practice that can reduce total manure mass and volume while creating a stabilized product that has less odor and fewer pathogens. However, composting animal manures can lead to high N loss via ammonia volatilization and increased concentrations of nonvolatile nutrients. The objective of this study was to measure copper (Cu) and zinc (Zn) concentrations in runoff water from plots fertilized with composted and fresh poultry litter. Seven treatments were evaluated in the first year: (i) unfertilized control, (ii) fresh poultry litter, (iii) normal compost (no amendment), (iv) composted litter with alum, (v) composted litter with phosphoric acid, (vi) composted litter with a microbial mixture, and (vii) composted litter with alum + microbial mixture. Six of these treatments were evaluated in Year 2 (alum + microbial mixture was not evaluated in Year 2). Rainfall simulators were used to produce a 5 cm h storm event sufficient in length to cause 30 min of continuous runoff. Concentrations of Cu and Zn were elevated in compost compared with fresh poultry litter. However, metal concentrations in compost did not correlate well with metal concentrations in runoff water and may have been affected by compost maturity and amendment. Total Cu and Zn concentrations in runoff water did not differ between alum amended compost and fresh poultry litter in each year. PMID- 27695742 TI - An Evaluation of the Contribution of Macro- and Microelements from Colonial Nesting Waterbirds to Surface Water. AB - Macro- and microelements contained in the feces of cattle egrets () and other colonial birds in heronries can be sources of contamination of nearby waterways. Concentrations of the macroelements potassium (K), calcium (Ca), magnesium (Mg), sodium (Na), sulfur (S) and the microelements zinc (Zn), copper (Cu), iron (Fe), manganese (Mn), and boron (B) were measured in water and fecal samples collected from four locations containing heronries during the breeding seasons of 2011, 2012, and 2013. Nitrogen and phosphorus were measured but not reported in this study. Concentrations of K in feces ranged from 8.19 * 10 +/- 4.38 * 10 to 4.88 * 10 +/- 7.57 * 10 mg kg, and concentrations in water ranged from 3.92 +/- 0.05 to 17.93 +/- 0.37 mg L. Similarly, concentrations of Ca in feces ranged from 4.17 * 10 +/- 1.84 * 10 to 1.16 * 10 +/- 4.14 * 10 mg L, and concentrations in water ranged from 25.28 +/- 0.89 to 67.88 +/- 2.02 mg L. When birds nested directly over water, concentrations of K, Ca, and Mg in water were significantly higher ( < 0.05) than concentrations in water adjacent to birds nesting on islands. The results from this study show that macroelements from avian feces have the potential to enrich surface water and to negatively affect surface water quality. These results provide information regarding the contribution of nutrients from heronries (comprised primarily by cattle egrets) to watersheds. PMID- 27695744 TI - Transport of Glyphosate and Aminomethylphosphonic Acid under Two Soil Management Practices in an Italian Vineyard. AB - Worldwide, glyphosate is the most widely used herbicide in controlling the growth of annual and perennial weeds. An increasing number of studies have highlighted the environmental risk resulting from the use of this molecule in aquatic and terrestrial ecosystems. The objective of the study was to determine the transport of glyphosate and its degradation product, aminomethylphosphonic acid (AMPA), through runoff and transported sediment from a vineyard under two different soil management systems: harrowed inter-row (HR) and permanent grass covered inter-row (GR). The study was performed over a period of 4 yr. Glyphosate and AMPA concentrations were found to be higher in runoff and in transported sediment from HR compared with GR, regardless of the amount of runoff and transported sediment. The mean annual percentages of glyphosate loss, via runoff and transported sediment, were about 1.37 and 0.73% for HR and GR, respectively. Aminomethylphosphonic acid represented approximately 30.9 and 40.0% of the total glyphosate losses in GR and HR, respectively. Moreover, results suggested that rains occurring within 4 wk after treatment could cause the transport of glyphosate and AMPA in high concentrations. Soil analyses indicated that glyphosate content was below detection within 1 yr, whereas AMPA remained in the soil profiles along the vine row and in the inter-row. Results indicated that GR can reduce soil and herbicide loss by runoff in vineyard cropping system.

AB - Agricultural N fertilization is the dominant driver of increasing atmospheric nitrous oxide (NO) concentrations over the past half-century, yet there is considerable uncertainty in estimates of NO emissions from agriculture. Such estimates are typically based on the amount of N applied and a fertilizer-induced emission factor (EF), which is calculated as the difference in emissions between a fertilized plot and a zero-N control plot divided by the amount of N applied. A fertilizer-induced EF of 1% is currently recognized by the Intergovernmental Panel on Climate Change (IPCC) based on several studies analyzing published field measurements of NO emissions. Although many zero-N control plots used in these measurements received historical N applications, the potential for a residual impact of these inputs on NO emissions has been largely ignored and remains poorly understood. To address this issue, we compared NO emissions under laboratory conditions from soils sampled within zero-N control plots that had historically received N inputs versus soils from plots that had no N inputs for 20 yr. Historical N fertilization of zero-N control plots increased initial NO emissions by roughly one order of magnitude on average relative to historically unfertilized control plots. Higher NO emissions were positively correlated with extractable N and potentially mineralizable N. This finding suggests that accounting for fertilization history may help reduce the uncertainty associated with the IPCC fertilizer-induced EF and more accurately estimate the contribution of fertilizer N to agricultural NO emissions, although further research to demonstrate this relationship in the field is needed.

AB - Land application of manure containing antimicrobials results in the dispersion of the antimicrobials in agro-ecosystems. Dissipation of excreted antimicrobials in seasonally frozen agricultural soils has not been fully characterized under field conditions. This study investigated the field dissipation kinetics of chlortetracycline, sulfamethazine, and tylosin over a 10-mo period after fall application of manure from cattle () administered 44 mg chlortetracycline (chlortetracycline treatment [CTC]), 44 mg each of chlortetracycline and sulfamethazine (CTCSMZ), or 11 mg tylosin per kg feed daily. Antimicrobial concentrations in manured soil reflected the same relative concentrations in manure: chlortetracycline > sulfamethazine > tylosin. The first-order dissipation half-life (DT) for chlortetracycline from the CTCSMZ treatment was 77 d during the growing season and 648 d during the nongrowing season when the soil was frozen for an extended period. By comparison, dissipation of chlortetracycline added alone (treatment CTC) did not differ significantly between the two seasons (mean DT, 121 d). During the nongrowing season, chlortetracycline from CTC dissipated faster ( = 0.004) than that from the CTCSMZ treatment, indicating that the presence of sulfamethazine may have altered the dissipation of chlortetracycline. Dissipation kinetics for sulfamethazine and tylosin were not determined due to low detection in the manure-amended soil. Sulfamethazine was detected (up to 16 +/- 10 ug kg) throughout the 10-mo monitoring period. Tylosin concentration was <=11 +/- 6.6 ug kg and gradually dissipated. Chlortetracycline was detectable 10 mo after application in the seasonally frozen soil, indicating a risk for residue build-up in the soil and subsequent offsite contamination. PMID- 27695747 TI - Simulated Effects of Soil Texture on Nitrous Oxide Emission Factors from Corn and Soybean Agroecosystems in Wisconsin. AB - Soil texture is known to have an influence on the physical and biological processes that produce NO emissions in agricultural fields, yet comparisons across soil textural types are limited by considerations of time and practicality. We used the DayCent biogeochemical model to assess the effects of soil texture on NO emissions from agriculturally productive soils from four counties in Wisconsin. We validated the DayCent model using field data from 2 yr of a long-term (approximately 20-yr) cropping systems trial and then simulated yield and NO emissions from continuous corn ( L.) and corn-soybean ( L.) cropping systems across 35 Wisconsin soil series classified as either silt loam, sandy loam, or loamy sand. Silt loam soils had the highest NO emissions of all soil types, exhibiting 80 to 158% greater mean emissions and 100 to 282% greater emission factors compared with loamy sand and sandy loam soils, respectively. The model predicts that for these soils under these cropping systems, denitrification constituted the majority of the NO flux only in the silt loam soils. However, across all soil textures, locations, and years, denitrification explained the most variation (74-98%) in total NO emissions. Our results suggest that soil texture is an important factor in determining a range of NO emission characteristics and is critical for estimating future NO emissions from agricultural fields. PMID- 27695748 TI - Subsurface Transport of in Soils of Wisconsin's Carbonate Aquifer Region. AB - is a waterborne pathogen known to have a significant reservoir in bovine manure. Land-dependent manure disposal may not result in significant or reliable pathogen attenuation and, therefore, presents a risk for transport of pathogenic spp. to groundwater. One factor missing in the existing literature is the role soil characteristics play in affecting oocyst transport. Of specific concern in regions with carbonate geology are macropores and other soil structures that contribute to preferential flow. Therefore, research is needed to understand soil type effects and important transport pathways for pathogens such as oocysts to drinking water wells. This study investigated transport potential in several soils overlying Wisconsin's vulnerable carbonate aquifer and related the soil transport to soil series and textural class. Experimental work involved monitoring the transport of oocysts through intact soil columns of different soil series under simulated rain conditions. Results demonstrate that a significant portion of oocysts will sorb or be physically entrapped in the soil, especially in soil with high clay content. However, silt loam soils with comparatively lower clay content demonstrated an ability to transport oocysts through the soil profile primarily via the first flush of water infiltrating through soil macropores. The rate of oocyst migration in silt loam soils paralleled the bromide tracer front, thus bypassing the soils' ability to strain or adsorb oocysts out of infiltrating water. Nevertheless, proper manure treatment and management are necessary to minimize public health risks. PMID- 27695749 TI - Assessment and Synthesis of 50 Years of Published Drainage Phosphorus Losses. AB - The prevalence of anthropogenic drainage systems in intensively cropped areas across North America combined with the degradation of important freshwater resources in these regions has created a critical intersection where understanding phosphorus (P) transport in drainage waters is vital. In this study, drainage-associated nutrient load data were retrieved and quantitatively analyzed to develop a more comprehensive understanding of the P loading and crop yield impacts of agronomic management practices within drained landscapes. Using the Drain Load table in the MANAGE (Measured Annual Nutrient loads from AGricultural Environments) database, the effect of factors such as soil characteristics, tillage, and nutrient management on P loading were analyzed. Across site-years, generally less than 2% of applied P was lost in drainage water, which corroborates the order of magnitude difference between agronomic P application rates and P loadings that can cause deleterious water quality impacts. The practice of no-till significantly increased drainage dissolved P loads compared with conventional tillage (0.12 vs. 0.04 kg P ha). The timing and method of P application are both known to be important for P losses, but these conclusions could not be verified due to low site-year counts. Findings indicate there is a substantial need for additional field-scale studies documenting not only P losses in drainage water but also important cropping management, nutrient application, soil property, and drainage design impacts on such losses.

AB - Phosphorus is among the essential nutrients applied to sugarcane ( L.) fields in the form of a fertilizer mixture (N, P, and K) in southwestern Florida. Sorption coefficient is used for modeling P movement, and in this study, we hypothesized that the sorption coefficient determined using fertilizer mixture (N, P, and K) will be significantly different from values determined using KCl and CaCl, the electrolytes most commonly used for conducting sorption experiments. Supporting electrolytes, 0.01 mol L KCl, 0.005 mol L CaCl, deionized (DI) water, simulated Florida rain, and fertilizer mixture prepared in Florida rain were used to characterize P sorption. Immokalee (Sandy, siliceous, hyperthermic Arenic Alaquods) and Margate (Sandy, siliceous hyperthermic Mollic Psammaquents) are the dominant mineral soils used for sugarcane production in southwestern Florida; we used the A and B horizons of Margate soil and the A and B horizons of the Immokalee soil for sorption experiments in this study. Freundlich sorption isotherms described P sorption data. The Freundlich sorption isotherm coefficients followed the trend 0.005 mol L CaCl > 0.01 mol L KCl ~ fertilizer mixture > simulated Florida rain ~ DI water. Sorption coefficients were used for modeling P movement with HYDRUS 1D; similar P results were obtained with the 0.01 mol L KCl and fertilizer mixture electrolyte treatments. The sorption coefficient for DI water and simulated Florida rain overpredicted P movement. The P sorption data showed the importance of choosing the appropriate electrolyte for conducting experiments based on the composition of fertilizer. PMID- 27695751 TI - Responses of Reclamation Plants to High Root Zone pH: Effects of Phosphorus and Calcium Availability. AB - Low phosphorus (P) availability and high pH inhibit plant growth in calcareous soils and some oil sands reclamation sites in northeastern Alberta, Canada. In this study, we used a split-root hydroponic setup to test the effects of supplemental P with different calcium (Ca) concentrations and root-zone pH conditions on the growth and physiological response of trees commonly found in the region: paper birch ( Marsh.), trembling aspen ( Michx.), green alder [ (Chaix) DC.], and black spruce [ (Mill.) Britton, Sterns & Poggenb.] seedlings. Plant roots were divided and treated with different combinations of P (0.5 and 15 mmol L), Ca (2 and 50 mmol L), and pH (5.0 and 9.0) for 6 wk. After that time, we measured seedling height, net photosynthesis and transpiration rates, and the concentration of chlorophyll and different elements in the leaves. Plant responses varied between species; black spruce was most resistant to high pH and high Ca concentrations. We did not find any strong beneficial effects of adding P to plants subjected to high root zone pH and high Ca concentration. However, exposure of part of the root system to low pH alleviated the effects of high pH, likely through the improved supply of micronutrients. Because pH conditions are often not uniform in disturbed sites and reclamation soils, our findings may help improve potential reclamation and phytoremediation strategies for the oil sands, bauxite, and coal-combustion residue utilization industries. PMID- 27695752 TI - Biochar Properties Influencing Greenhouse Gas Emissions in Tropical Soils Differing in Texture and Mineralogy. AB - The ability of biochar applications to alter greenhouse gases (GHGs) (CO, CH, and NO) has been attracting research interest. However, inconsistent published results necessitate further exploration of potential influencing factors, including biochar properties, biochar rates, soil textures and mineralogy, and their interactions. Two short-term laboratory incubations were conducted to evaluate the effects of different biochars: a biochar with low ash (2.4%) and high-volatile matter (VM) (35.8%) contents produced under low-temperature (350 degrees C) traditional kiln and a biochar with high ash (3.9%) and low-VM (14.7%) contents produced with a high-temperature (800 degrees C) Flash Carbonization reactor and different biochar rates (0, 2, and 4% w/w) on the GHG emissions in a loamy-sand Ultisol and a silty-clay-loam Oxisol. In the coarse-textured, low buffer Ultisol, cumulative CO and CH emissions increased with increasing VM content of biochars; however, CO emission sharply decreased at 83 MUg VM g soil. In the fine-textured, high-buffer Oxisol, there were significant positive effects of VM content on cumulative CO emission without suppression effects. Regarding cumulative NO emission, there were significant positive effects in the Mn-rich Oxisol. Ash-induced increases in soil pH had negative effects on all studied GHG emissions. Possible mechanisms include the roles biochar VM played as microbial substrates, a source of toxic compounds and complexing agents reducing the toxicity of soil aluminum and manganese, and the role of biochar ash in increasing soil pH affecting GHG emissions in these two contrasting soils. PMID- 27695753 TI - Urban Air Pollution in Taiwan before and after the Installation of a Mass Rapid Transit System. AB - Urbanization causes air pollution in metropolitan areas, coupled with meteorological factors that affect air quality. Although previous studies focused on the relationships of urbanization, air pollution, and climate change in Western countries, this study evaluated long-term variations of air quality and meteorological factors in Taiwanese metropolitan areas (Taipei area, Taichung City, and Kaohsiung City) and a rural area (Hualien County) between 1993 and 2012. The influence of a mass rapid transit (MRT) system on air quality was also evaluated. Air pollutant concentrations and meteorology data were collected from Taiwan Environmental Protection Administration (TEPA) air monitoring stations and Central Weather Bureau stations in the surveyed areas, respectively. Analyses indicate that levels of air pollution in metropolitan areas were greater than in the rural area. Kaohsiung City had the highest levels of O, SO, and particulate matter 2.5 or 10 um in diameter (PM and PM). Clear downward trends for CO, NO, PM, PM, and especially SO concentrations were found in the surveyed areas, whereas O showed no decrease. Both O and PM concentrations showed similar bimodal seasonal distributions. Taiwan's air quality has improved significantly since 1993, indicating the effectiveness of promoting air pollution strategies and policies by the TEPA. Air pollution had an obvious improvement in Taipei area after the MRT system began operations in 1996. Because global climate may potentially affect urban air pollution in Taiwan, further study to clarify the mechanisms by which air pollution may affect human health and other biological effects is warranted. PMID- 27695754 TI - Comparison of the Physical and Chemical Properties of Laboratory and Field-Aged Biochars. AB - The long-term impact of biochar on soil properties and agronomic outcomes is influenced by changes in the physical and chemical properties of biochars that occur with time (aging) in soil environments. Fresh biochars, however, are often used in studies because aged biochars are generally unavailable. Therefore, a need exists to develop a method for rapid aging of biochars in the laboratory. The objectives of this study were to compare the physicochemical properties of fresh, laboratory-aged (LA), and field-aged (FA) (>=3 yr) biochars and to assess the appropriateness of a laboratory aging procedure that combines acidification, oxidation, and incubations as a mimic to field aging in neutral or acidic soil environments. Twenty-two biochars produced by fast and slow pyrolysis, and gasification techniques from five different biomass feedstocks (hardwood, corn stover, soybean stover, macadamia nut shells, and switchgrass) were studied. In general, both laboratory and field aging caused similar increases in ash-free volatile matter (% w/w), cation and anion exchange capacities, specific surface area, and modifications in oxygen-containing surface functional groups of the biochars. However, ash content increased for FA (18-195%) and decreased for LA (22-74%) biochars, and pH decreased to a greater extent for LA (2.8-6.7 units) than for FA (1.6-3.8 units) biochars. The results demonstrate that the proposed laboratory aging procedure is effective for predicting the direction of changes in biochar properties on field aging. However, in the future we recommend using a less aggressive acid treatment. PMID- 27695756 TI - Influence of Acidification on the Partitioning of Steroid Hormones among Filtrate, Filter Media, and Retained Particulate Matter. AB - Hormone contamination of aquatic systems has been shown to have deleterious effects on aquatic biota. However, the assessment of hormone contamination of aquatic environments requires a quantitative evaluation of the potential effects of sample preservation on hormone concentrations. This study investigated the influence of acidification (pH 2) of surface water samples on the partitioning of hormones among filtrate, filter media, and filter-retained particulate matter. Hormones were spiked into unpreserved and sulfuric acid-preserved ultrapure water and surface water runoff samples. The samples were filtered, and hormones were extracted from the filter and filtrate and analyzed by high-performance liquid chromatography. Acidification did not influence the partitioning of hormones onto the filter media. For the majority of the hormones investigated in this study, the partitioning of hormones to the filter-retained particulate matter was not influenced by acidification. Acidification increased the partitioning of progesterone and melengestrol acetate onto the retained particulate matter (about 25% for both analytes). Incorporation of an isotopically labeled internal standard (ISTD) for progesterone accounted for the loss of progesterone to the filter-retained particulates and resulted in accurate concentrations of progesterone in the filtrate. The incorporation of an ISTD for melengestrol acetate, however, was unable to account for the loss of melengestrol acetate to the retained particulates and resulted in underestimations of melengestrol acetate in the filtrate. Our results indicate that the analysis of melengestrol acetate in acid preserved surface runoff samples should be conducted on the filter-retained particulates as well as the filtrate. PMID- 27695755 TI - Long-term Effects of Rock Type on Appalachian Coal Mine Soil Properties. AB - Rock-derived overburden material is used as a topsoil substitute for reclamation of Appalachian coal mines. We evaluated five mixtures ( = 4 each) of sandstone (SS) and siltstone (SiS) overburden as topsoil substitutes for 25+ years to quantify changes in mine soil properties. The study area was planted only to tall fescue [ (Schreb.)], but over 50 herbaceous species invaded over time. Standing biomass was highest in early years (5.2-9.3 Mg ha in 1983) and was strongly affected by rock type (SS > SiS), declined significantly by 1989 (1.5-2.4 Mg ha), and then increased again (2*) by 2008. However, there was no long-term rock type effect on standing biomass. Rock fragments and texture differed after 26 yr, with fewer rock fragments in the SS-dominated mixtures (53 vs. 77% in SiS) and lower sand and higher clay in the SiS-dominated mixtures. Soil pH initially ranged from 5.45 (SS) to 7.45 (SiS), dropped for several years, increased in all SiS mixes, and then slowly declined again to 5.65 (SS) to 6.46 (SiS) over the final 15 yr. Total N, organic matter, and cation exchange capacity increased with time, and extractable P decreased. Chemical weathering was most apparent initially, but physical weathering of rock fragments and changes in texture continued throughout the study period. Influences of original rock mixtures remained apparent after 25+ yr in both physical and chemical properties of these mine soils, which remained much coarser than local native soils but were higher in pH, exchangeable cations, and extractable P. PMID- 27695757 TI - Nutrient Runoff Losses from Liquid Dairy Manure Applied with Low-Disturbance Methods. AB - Manure applied to cropland is a source of phosphorus (P) and nitrogen (N) in surface runoff and can contribute to impairment of surface waters. Tillage immediately after application incorporates manure into the soil, which may reduce nutrient loss in runoff as well as N loss via NH volatilization. However, tillage also incorporates crop residue, which reduces surface cover and may increase erosion potential. We applied liquid dairy manure in a silage corn ( L.)-cereal rye ( L.) cover crop system in late October using methods designed to incorporate manure with minimal soil and residue disturbance. These include strip-till injection and tine aerator-band manure application, which were compared with standard broadcast application, either incorporated with a disk or left on the surface. Runoff was generated with a portable rainfall simulator (42 mm h for 30 min) three separate times: (i) 2 to 5 d after the October manure application, (ii) in early spring, and (iii) after tillage and planting. In the postmanure application runoff, the highest losses of total P and dissolved reactive P were from surface-applied manure. Dissolved P loss was reduced 98% by strip-till injection; this result was not statistically different from the no-manure control. Reductions from the aerator band method and disk incorporation were 53 and 80%, respectively. Total P losses followed a similar pattern, with 87% reduction from injected manure. Runoff losses of N had generally similar patterns to those of P. Losses of P and N were, in most cases, lower in the spring rain simulations with fewer significant treatment effects. Overall, results show that low-disturbance manure application methods can significantly reduce nutrient runoff losses compared with surface application while maintaining residue cover better than incorporation by tillage. PMID- 27695758 TI - Polycyclic Aromatic Hydrocarbon Contamination in Soils of San Mateo Ixtatan, Guatemala: Occurrence, Sources, and Health Risk Assessment. AB - Exposure to high concentrations of carcinogenic pollutants in soils and sediments can result in increased health risks. Determining the levels and sources of contamination in developing communities is important for helping to reduce pollution and mitigate the risk of exposure. In the Mayan community of San Mateo Ixtatan, Guatemala, 24 samples of topsoil from urban, peri-urban, and agricultural sites and six samples of river sediment were collected and analyzed for 17 polycyclic aromatic hydrocarbons (PAHs). The sum of the concentrations of these PAHs at the urban and peri-urban sites ranged from 460 to 3251 MUg kg (mean, 1401 MUg kg), whereas at agricultural sites the range was 350 to 2087 MUg kg (mean, 1038 MUg kg). Analysis to identify and apportion the source showed that the PAHs emitted from wood stoves contributed 71 and 76% of the total PAHs in urban and agricultural areas soils, respectively. The calculated incremental lifetime cancer risk due to the ingestion of soil, dermal contact, and dietary intake through corn consumption was greater than the acceptable level of 10 established by the USEPA. Our findings suggest that the residents of rural communities can be at increased cancer risk despite little or no industrial activity in the local area. Alternate domestic fuel sources should be considered to reduce the health risk in local communities. PMID- 27695759 TI - Impact of Kura Clover Living Mulch on Nitrous Oxide Emissions in a Corn-Soybean System. AB - Nitrous oxide (NO), produced primarily in agricultural soils, is a potent greenhouse gas and is the dominant ozone-depleting substance. Efforts to reduce NO emissions are underway, but mitigation results have been inconsistent. The leguminous perennial kura clover ( M. Bieb.) (KC) can grow side-by-side with cash crops in rotational corn ( L.)-soybean ( L.) systems. With biological nitrogen fixation, KC provides land managers an opportunity to reduce external fertilizer inputs, which may diminish problematic NO emissions. To investigate the effect of a KC living mulch on NO emissions, automated soil chambers coupled to a NO analyzer were used to measure hourly fluxes from April through October in a 2-yr corn-soybean (CS) rotation. Emissions from the KC treatment were significantly greater than those from the conventional CS treatment despite the fact that the KC treatment received substantially less inorganic nitrogen fertilizer. A seasonal tradeoff was observed with the KC treatment wherein emissions before strip-tillage were reduced but were surpassed by high losses after strip-tillage and postanthesis. These results represent the first reported measurements of NO emissions from a KC-based living mulch. The findings cast doubt on the efficacy of KC for mitigating NO loss in CS systems. However, if KC reduces nitrate leaching losses, as has been reported elsewhere, it may result in lower indirect (offsite) NO emissions. PMID- 27695760 TI - Methane and Nitrous Oxide Emissions from Cattle Excreta on an East African Grassland. AB - Greenhouse gas (GHG) emission measurements from livestock excreta in Africa are limited. We measured CH and NO emissions from excreta of six Boran () and six Friesian () steers near Nairobi, Kenya. The steers were fed one of three diets (T1 [chaffed wheat straw], T2 [T1 + Meissner - 0.2% live weight per day], and T3 [T1 + calliandra - 0.4% live weight every 2 d]). The T1 diet is similar in quality to typical diets in the region. Calliandra is a leguminous fodder tree promoted as a feed supplement. Fresh feces and urine were applied to grasslands and emissions measured using static chambers. Cumulative 28-d fecal emissions were 302 +/- 52.4 and 95 +/- 13.8 mg CH-C kg dry matter for Friesen and Boran steers, respectively, and 11.5 +/- 4.26 and 24.7 +/- 8.32 mg NO-N kg dry matter for Friesian and Boran steers, respectively. For urine from Friesian steers, the NO emissions were 2.8 +/- 0.64 mg NO-N 100 mL urine. The CH emission factors (EFs) (246 +/- 49.5 and 87 +/- 12.7 g CH-C yr animal for Friesan and Boran, respectively) were lower than the International Panel on Climate Change EFs (750 g CH-C animal yr), whereas the NO EFs (0.1 and 0.2% for the Friesian and Boran feces, respectively, and 1.2% for urine) were also lower than International Panel on Climate Change estimates. The low N content of the excreta likely caused the low emissions and indicates that current models probably overestimate CH and NO emissions from African livestock manure. PMID- 27695761 TI - Kriging Models Predicting Atrazine Concentrations in Surface Water Draining Agricultural Watersheds. AB - The performance of kriging methods in predicting maximum m-day (m = 1, 7, 14, or 30) rolling averages of atrazine concentrations in 42 site-years of Midwest Corn Belt watersheds under two systematic sampling designs (sampling every 7 or 14 d) was examined. Daily atrazine monitoring data obtained from the Atrazine Ecological Monitoring Program in the Corn Belt region (2009-2014) were used in the evaluation. Both ordinary and universal kriging methods were considered, with the covariate for universal kriging derived from the deterministic Pesticide Root Zone Model (PRZM). For the maximum 1-d rolling averages, prediction did not differ among methods. For rolling averages of longer duration (m > 1), predictions obtained by linear interpolation on a logarithmic scale were better (up to 15% lower for 7-d sampling and 22% lower for 14-d sampling in terms of the relative root mean squared prediction error) than those obtained by linear interpolation on the original linear scale and also less variable. For kriging methods, empirical semivariograms of daily atrazine time series suggest a negligible noise process, supported by replicate analysis of selected field samples; piecewise linear semivariogram models were found to perform best for predicting sampled data. We demonstrate that kriging prediction intervals offer close to nominal coverage for unsampled values. PMID- 27695762 TI - Long-term Impact of Sewage Sludge Application on biovar : An Evaluation Using Meta-Analysis. AB - The Long-Term Sludge Experiment (LTSE) began in 1994 at nine UK field sites as part of continuing research into the effects of sludge-borne heavy metals on soil fertility. The long-term effects of Zn, Cu, and Cd on the most probable numbers of cells (MPN) of biovar were monitored for 8 yr in sludge-amended soils. To assess the statutory limits set by the UK Sludge (Use in Agriculture) Regulations, the experimental data were reviewed using statistical methods of meta-analysis. Previous LTSE studies have focused predominantly on statistical significance rather than effect size, whereas meta-analysis focuses on the magnitude and direction of an effect, i.e., the practical significance rather than its statistical significance. Results showed Zn to be the most toxic element causing an overall significant decrease in MPN of -26.6% during the LTSE. The effect of Cu showed no significant effect on MPN at concentrations below the UK limits, although a -5% decrease in MPN was observed in soils where total Cu ranged from 100 to <135 mg kg. Overall, there was nothing to indicate that Cd had a significant effect on MPN below the current UK statutory limit. In summary, the UK statutory limit for Zn appears to be insufficient for protecting from Zn toxicity effects. PMID- 27695763 TI - Co-transport of Pesticide Acetamiprid and Silica Nanoparticles in Biochar-Amended Sand Porous Media. AB - The role of biochar as a soil amendment on the transport of acetamiprid, a widely used neonicotinoid pesticide, is little known. We conducted saturated column experiments to examine cotransport of acetamiprid and silica nanoparticles (NPs) in pure and biochar-amended sands. Retention of acetamiprid was minor in the pure sand, whereas application of biochar in the sand significantly increased retention. Retention was greater at lower ionic strengths and near neutral pH values and was attributed to biodegradation and sorption through pi-pi interaction and pore filling. The convection-diffusion equation with inclusion of first-order sorption, desorption, and degradation well described the transport of acetamiprid in the biochar-amended sand. The simulation results show that the sorption rate did not change with pH. This is because the acetamiprid is nonionic and cannot be bonded with the biochar by protonation or deprotonation. The desorption rate was independent of variation of solution chemistry, indicating that desorption was a physical process (i.e., pore diffusion). Application of biochar in the sand had little influence on the transport of silica NPs in NaCl but caused complete attachment in CaCl. Energy dispersive X-ray spectroscopy suggested that the enhanced attachment was due to cation bridging between silica NPs and functional groups in biochar by the Ca. The co-presence of acetamiprid and silica NPs in the solutions enhanced transport of acetamiprid and NPs in the biochar-amended sand by competing for the binding sites on the biochar surfaces. PMID- 27695764 TI - Nitrous Oxide Emissions from a Golf Course Fairway and Rough after Application of Different Nitrogen Fertilizers. AB - Few studies have quantified nitrous oxide (NO) emissions from intensively managed turfgrass systems on golf courses. Fertilizer treatments consisting of urea with inhibitors of nitrification and urease (INU), polymer-coated urea (PCU), and uncoated balanced methylene urea (BMU) chain, which use different mechanisms to control the release of N substrate, were applied to a golf course fairway and rough three times during the 2011 growing season at a rate of 50 kg N ha per application. The vented chamber method was used to measure turf-soil-atmospheric NO exchange. Cumulative emissions from fairway INU, PCU, and BMU treatments totaled 6.5, 1.9, and 7.6 kg NO-N ha yr, representing a 4.02, 1.25, and 4.75% loss of total N applied, respectively. Summer INU and BMU fertilization to the fairway produced the greatest NO fluxes. Rapid fluxes during the summer were likely related to low physiological activity in cool-season turfgrass and to warm, wet soil conditions that increased denitrification rates. However, PCU applied to the fairway was more resistant to NO losses than other fertilizer treatments. Fertilizer treatments applied to the rough had cumulative emissions of 2.4, 1.50, and 1.49 kg NO-N ha yr from INU, PCU, and BMU treatments, corresponding to a 1.21, 0.62, and 0.61% loss of total N applied, respectively. The lower NO emission on roughs was likely associated with greater carbon pools, lower soil moisture, and lower temperatures. This study supports the effectiveness of PCU to reduce NO emission from cool-season turfgrass fairways when soil conditions favored denitrification during warm periods. Applying INU and BMU when soil was cool and dry was effective in moderating NO losses. PMID- 27695765 TI - Decreasing Phosphorus Loss in Tile-Drained Landscapes Using Flue Gas Desulfurization Gypsum. AB - Elevated phosphorus (P) loading from agricultural nonpoint-source pollution continues to impair inland waterbodies throughout the world. The application of flue gas desulfurization (FGD) gypsum to agricultural fields has been suggested to decrease P loading because of its high calcium content and P sorbing potential. A before-after control-impact paired field experiment was used to examine the water quality effects of successive FGD gypsum applications (2.24 Mg ha; 1 ton acre each) to an Ohio field with high soil test P levels (>480 ppm Mehlich-3 P). Analysis of covariance was used to compare event discharge, dissolved reactive P (DRP), and total P (TP) concentrations and loadings in surface runoff and tile discharge between the baseline period (86 precipitation events) and Treatment Period 1 (42 precipitation events) and Treatment Period 2 (84 precipitation events). Results showed that, after the first application of FGD gypsum, event mean DRP and TP concentrations in treatment field tile water were significantly reduced by 21 and 10%, respectively, and DRP concentrations in surface runoff were significantly reduced by 14%; however, no significant reductions were noted in DRP or TP loading. After the second application, DRP and TP loads were significantly reduced in surface runoff (DRP, 41%; TP 40%), tile discharge (DRP, 35%; TP, 15%), and combined (surface + tile) discharge (DRP, 36%; TP, 38%). These findings indicate that surface application of FGD gypsum can be used as a tool to address elevated P concentrations and loadings in drainage waters.

AB - Unregulated and event-driven agricultural tile drainage discharge poses several challenges that potentially limit the nitrate (NO) removal performance of woodchip-based wetlands constructed to intercept subsurface tile drain flows. Laboratory column tests were conducted to evaluate the biogeochemical response of mixed reactive media (woodchips-seashells and woodchips-Filtralite mixtures) at two woodchip ratios to changes in hydraulic loading rate (HLR). The tests involved continuous loading of aerated artificial drainage water spiked with NO-N and tritium (HO) breakthrough experiments. Flow-normalized NO reduction rates ranged from 0.35 to 3.97 g N m L, corresponding to N removal efficiencies of 5 to 64%, depending on HLR and filter mixtures. At high HLRs, oxic conditions prevailed in the woodchip filters, resulting in reduced N removal. At low HLRs, progressively lower pore-water velocities extended the period for consumption of terminal electron acceptors, increasing N removal. When increasing the content of mineral material, N removal declined, probably due to a lower denitrifying biomass at lower woodchip mass. The effect of woodchip ratios on solute transport characteristics was difficult to assess. However, woodchip media including a mineral fraction of crushed seashells demonstrated the highest N removal rates and efficiencies, most likely due to the alkalizing effect of the seashells. In conclusion, filter mixtures consisting of woodchips and seashells were the most effective material for N removal in subsurface flow-constructed wetlands treating agricultural drainage water.

AB - Surplus nitrogen (N) estimates, principal component analysis (PCA), and end member mixing analysis (EMMA) were used in a multisite comparison contrasting the fate of N in diverse agricultural watersheds. We applied PCA-EMMA in 10 watersheds located in Indiana, Iowa, Maryland, Nebraska, Mississippi, and Washington ranging in size from 5 to 1254 km with four nested watersheds. Watershed Surplus N was determined by subtracting estimates of crop uptake and volatilization from estimates of N input from atmospheric deposition, plant fixation, fertilizer, and manure for the period from 1987 to 2004. Watershed average Surplus N ranged from 11 to 52 kg N ha and from 9 to 32% of N input. Solute concentrations in streams, overland runoff, tile drainage, groundwater (GW), streambeds, and the unsaturated zone were used in the PCA-EMMA procedure to identify independent components contributing to observed stream concentration variability and the end-members contributing to streamflow and NO load. End members included dilute runoff, agricultural runoff, benthic-processing, tile drainage, and oxic and anoxic GW. Surplus N was larger in watersheds with more permeable soils (Washington, Nebraska, and Maryland) that allowed greater infiltration, and oxic GW was the primary source of NO load. Subsurface transport of NO in these watersheds resulted in some removal of Surplus N by denitrification. In less permeable watersheds (Iowa, Indiana, and Mississippi), NO was rapidly transported to the stream by tile drainage and runoff with little removal. Evidence of streambed removal of NO by benthic diatoms was observed in the larger watersheds.

AB - Pesticides play an important role in the protection of different crops. Among the diverse sets of pesticides used all over the world, the organophosphates are the most widely used group. Profenofos [O-(4-bromo-2-chlorophenyl) O-ethyl S-propyl phosphorothioate] is one of the most largely used organophosphate insecticides on field crops, vegetables, and fruit crops. The World Health Organization classifies this compound as moderately hazardous (Toxicity Class II), and its residues have been found in vegetables like okra [ (L.) Moench], gooseberries ( sp.), green chilies [ (L.)], curry leaves [ (L.) Spreng], mint leaves [ (L.)], and coriander leaves [ (L.)]. Dietary intake of profenofos (PFF) is the major exposure pathway for humans. When applied to agricultural fields, PFF residues spread into every part of the environment: ambient air, surface water, and soil. In this review, we discuss the worldwide usage of PFF pesticide, its toxic effects on humans and other living organisms in the environment, and biodegradation of this chemical by various microbial strains. To date, no complete biodegradation pathway has been established for PFF pesticide, calling for a study of this nature.

AB - United States Golf Association putting greens are susceptible to nitrogen (N) and phosphorus (P) leaching. Inorganic soil amendments are used to increase moisture and nutrient retention and may influence N and P leaching. This study was conducted to determine whether N and P leaching could be reduced using soil amendments and surfactant-modified soil amendments. Treatments included a control (sand), sand-peat, zeolite, calcined clay, hexadecyltrimethylammonium-zeolite, and hexadecyltrimethylammonium-calcined clay. Lysimeters were filled with a 30-cm rootzone layer of sand-peat (85:15 by volume), below which a 5-cm treatment layer of amendments was placed. A solution of NO-N, NH-N, and orthophosphate-P (2300, 2480, and 4400 MUg mL, respectively) was injected at the top of each lysimeter, and leachate was collected using an autocollector set to collect a 10-mL sample every min until four pore volumes were collected. Uncoated amendments, sand, and peat had no influence on NO-N retention, whereas hexadecyltrimethylammonium coated amendments reduced NO-N leaching to below detectable limits. Both coated and uncoated amendments reduced NH-N leaching, with zeolite reducing NH-N leached to near zero regardless of hexadecyltrimethylammonium coating. Pure sand resulted in a 13% reduction of applied orthophosphate-P leaching, whereas peat contributed to orthophosphate-P leaching. Surfactant-modified amendments reduced orthophosphate-P leaching by as much as 97%. Surfactant-modified soil amendments can reduce NO-N, NH-N, and orthophosphate-P leaching and, thus, may be a viable option for removing leached N and P before they enter surface or ground waters. PMID- 27695770 TI - High Nitrate Concentrations in Some Midwest United States Streams in 2013 after the 2012 Drought. AB - Nitrogen sources in the Mississippi River basin have been linked to degradation of stream ecology and to Gulf of Mexico hypoxia. In 2013, the USGS and the USEPA characterized water quality stressors and ecological conditions in 100 wadeable streams across the midwestern United States. Wet conditions in 2013 followed a severe drought in 2012, a weather pattern associated with elevated nitrogen concentrations and loads in streams. Nitrate concentrations during the May to August 2013 sampling period ranged from <0.04 to 41.8 mg L as N (mean, 5.31 mg L). Observed mean May to June nitrate concentrations at the 100 sites were compared with May to June concentrations predicted from a regression model developed using historical nitrate data. Observed concentrations for 17 sites, centered on Iowa and southern Minnesota, were outside the 95% confidence interval of the regression-predicted mean, indicating that they were anomalously high. The sites with a nitrate anomaly had significantly higher May to June nitrate concentrations than sites without an anomaly (means, 19.8 and 3.6 mg L, respectively) and had higher antecedent precipitation indices, a measure of the departure from normal precipitation, in 2012 and 2013. Correlations between nitrate concentrations and watershed characteristics and nitrogen and oxygen isotopes of nitrate indicated that fertilizer and manure used in crop production, principally corn, were the dominant sources of nitrate. The anomalously high nitrate levels in parts of the Midwest in 2013 coincide with reported higher-than normal nitrate loads in the Mississippi River. PMID- 27695771 TI - Alpha-linolenic acid treatment during oocyte maturation enhances embryonic development by influencing mitogen-activated protein kinase activity and intraoocyte glutathione content in pigs. AB - The purpose of this study was to examine the effects of alpha-linolenic acid (ALA) treatment during in vitro maturation (IVM) on nuclear maturation, intraoocyte glutathione (GSH) content, meiotic progression, and developmental competence after parthenogenesis (PA) and somatic cell nuclear transfer (SCNT) in pigs. Medium-199 containing 10% (vol/vol) porcine follicular fluid (PFF; PPF control) or 0.4% (wt/vol) fatty acid-free BSA (BSA control) was used for IVM. The proportion of oocytes reaching the metaphase II (MII) stage was not influenced by ALA treatment at various concentrations (50, 100, and 200 MU). However, treatment with 100 MU ALA significantly increased ( < 0.05) intraoocyte GSH content (1.19 vs. 1.00 and 0.92 pixels per oocyte, comparing the treated oocytes, BSA control, and PFF control, respectively) and embryonic development to the blastocyst stage after PA (47.1 vs. 35.5 and 35.2%) and SCNT (31.4 vs. 23.9 and 24.3%). ALA treatment (100 MU) accelerated oocyte maturation, and a higher proportion of ALA treated oocytes (89.6%) reached the MII stage than did the untreated controls (75.5%) at 33 h of IVM. Mitogen-activated protein kinase kinase inhibitor (U0126) treatment during IVM inhibited nuclear maturation and embryonic development after PA. However, 100 MU ALA completely counteracted the suppressive effect of U0126 on nuclear maturation and partially counteracted the effect on blastocyst formation. Our results demonstrate that treatment with 100 MU ALA during IVM improves developmental competence by accelerating nuclear maturation and also influencing cytoplasmic maturation, such as increased GSH content in IVM oocytes. PMID- 27695772 TI - Forage use to improve environmental sustainability of ruminant production. AB - Ruminants raised for meat and milk are important sources of protein in human diets worldwide. Their unique digestive system allows them to derive energy and nourishment from forages, making use of vast areas of grazing lands not suitable for arable cropping or biofuel production and avoiding direct competition for grain that can be used as human food. However, sustaining an ever-growing population of ruminants consuming forages poses a dilemma: while exploiting their ecological niche, forage-fed ruminants produce large amount of enteric methane, a potent greenhouse gas. Resolving this quandary would allow ruminants an expanded role in meeting growing global demands for livestock products. One way around the dilemma is to devise forage-based diets and feeding systems that reduce methane emissions per unit of milk or meat produced. Ongoing research has made significant strides toward this objective. A wider opportunity is to look beyond methane emissions alone and consider all greenhouse gas emissions from the entire livestock-producing system. For example, by raising ruminants in systems using forages, some of the methane emissions can be offset by preserving or enhancing soil carbon reserves, thereby withholding carbon dioxide from the air. Similarly, well-managed systems based on forages may reduce synthetic fertilizer use by more effective use of manure and nitrogen-fixing plants, thereby curtailing nitrous oxide emissions. The potential environmental benefits of forage-based systems may be expanded even further by considering their other ecological benefits, such as conserving biodiversity, improving soil health, enhancing water quality, and providing wildlife habitat. The quandary, then, can be alleviated by managing ruminants within a holistic land-livestock synchrony that considers not only methane emissions but also suppression of other greenhouse gases as well as other ecological benefits. Given the complexity of such systems, there likely are no singular "best-management" practices that can be recommended everywhere. Using systems-based approaches such as life cycle analysis, ruminant production can be tuned for local lands to achieve greatest net benefits overall. In many instances, such systems, based on forages, may maintain high output of milk and meat while also furnishing other ecosystem benefits, such as reduced overall greenhouse gas emissions. PMID- 27695773 TI - Influence of oral glucosamine supplementation in young horses challenged with intra-articular lipopolysaccharide. AB - Fourteen yearling Quarter horses (351 to 470 kg) were utilized in a randomized complete block design to evaluate potential of glucosamine hydrochloride (HCl) to mitigate intra-articular inflammation following a single inflammatory insult. Horses were blocked by BW, age, and sex, and randomly assigned to treatments for a 98-d experiment. Treatments consisted of a control diet (CON; = 7) fed 1% BW per d (as-fed) of concentrate only or a treatment diet ( = 7) of concentrate top dressed with 30 mg/kg BW glucosamine HCl (99.6% purity; GLU30) offered at 12 h intervals. Horses were maintained in individual stalls and offered approximately 1% BW per d of coastal bermudagrass hay (). Plasma and synovial fluid samples were obtained every 14 and 28 d, respectively, and stored at -20 degrees C, before analysis of glucosamine via HPLC. On d 84, an intra-articular lipopolysaccharide (LPS) challenge was conducted on all horses to determine ability of dietary glucosamine HCl supplementation to mitigate joint inflammation and cartilage metabolism. Carpal joints were randomly selected to receive 1 of 2 intra-articular treatments and included sterile lactated Ringer's (control; Contra) only or 0.5 ng LPS solution (LPS) obtained from O55:B5 into the radial carpal joint. Synovial fluid was obtained at pre-injection h 0 and 6, 12, 24, 128, and 336 h post-injection, and was analyzed for prostaglandin E (PGE), carboxypeptide of type II collagen (CPII) and collagenase cleavage neopeptide (C2C) biomarkers by commercial ELISA kits. Data were analyzed using PROC MIXED procedure of SAS. Plasma and synovial glucosamine tended ( = 0.10 and = 0.06, respectively) to increase over time in response to GLU30 compared to CON. There was a treatment by time interaction ( <= 0.01), with GLU30 increasing plasma glucosamine concentrations at 28 and 42 d when compared to CON. A treatment by time interaction ( <= 0.01) was observed with GLU30 increasing synovial glucosamine levels at d 28 and 84 ( <= 0.01 and = 0.05, respectively). Intra articular LPS increased ( <= 0.01) synovial PGE, C2C, and CPII levels. GLU30 decreased synovial PGE and C2C concentrations when compared to CON ( = 0.04 and = 0.05, respectively), while synovial levels of CPII increased ( <= 0.01) in GLU30 horses. These results indicate the potential for oral glucosamine HCl to mitigate intra-articular inflammation and influence cartilage turnover in a young horse model. PMID- 27695774 TI - Can a super sow be a robust sow? Consequences of litter investment in purebred and crossbred sows of different parities. AB - The aim of this project was to study the consequences of litter investment on physical characteristics in primiparous and multiparous sows in 3 Norwegian breeds (Norsvin Duroc [ = 12], Norsvin Landrace [ = 12], and crossbreeds [Norsvin Landrace and Swedish Yorkshire { = 15}]). We predicted that the maternal sow line (Norsvin Landrace) would invest more in their litter in term of higher weight at birth, resulting in a higher litter weight of weaned piglets but with the consequence of greater loss in body condition and a higher prevalence of shoulder lesions. It was predicted that this should be more pronounced in primiparous sows than in multiparous sows. As predicted, the maternal pure line (Norsvin Landrace) had higher litter investment in terms of litter weight at birth ( = 0.003) and litter weight at weaning ( = 0.050) as well as higher total litter investment (litter weight at weaning plus weight of dead piglets [stillborn and mummified piglets and weight of piglets that died after farrowing but before weaning]; = 0.050) and suffered larger losses of body condition ( = 0.016) and had a higher prevalence of shoulder lesions ( = 0.008) during lactation than other breeds. Moreover, only in Norsvin Landrace was development of shoulder lesions related to inadequate feed consumption ( = 0.006). This has become a major welfare concern of modern pig breeding. Although primiparous and multiparous sows had similar litter sizes, primiparous sows had lower litter investment in terms of litter weight at birth ( = 0.032) and litter weight at weaning ( = 0.007) as well as total litter investment ( = 0.008). Primiparous sows suffered greater losses in body condition ( = 0.012) and developed more shoulder lesions ( = 0.026) due to lower total feed consumption ( < 0.001) during lactation than multiparous sows. Especially in the highly productive maternal line (Norsvin Landrace), development of shoulder lesions during the lactation period was more pronounced in primiparous sows than in multiparous sows ( < 0.001). The selection program has shifted the balance to greater investments in earlier life, when sows still need resources for their own growth and development. This has resulted in a larger number of weaned piglets but at a higher sow welfare cost in terms of higher losses in body condition and a higher prevalence of shoulder lesions. Our results pinpoint the importance of improving the balance between economic traits and traits that improve welfare and longevity of the sows. PMID- 27695775 TI - Effects of wheat source and particle size in meal and pelleted diets on finishing pig growth performance, carcass characteristics, and nutrient digestibility. AB - Two experiments were conducted to test the effects of wheat source and particle size in meal and pelleted diets on finishing pig performance, carcass characteristics, and diet digestibility. In Exp. 1, pigs (PIC 327 * 1050; = 288; initially 43.8 kg BW) were balanced by initial BW and randomly allotted to 1 of 3 treatments with 8 pigs per pen (4 barrows and 4 gilts) and 12 pens per treatment. The 3 dietary treatments were hard red winter wheat ground with a hammer mill to 728, 579, or 326 MUm, respectively. From d 0 to 40, decreasing wheat particle size decreased (linear, < 0.033) ADFI but improved (quadratic, < 0.014) G:F. From d 40 to 83, decreasing wheat particle size increased (quadratic, < 0.018) ADG and improved (linear, < 0.002) G:F. Overall from d 0 to 83, reducing wheat particle size improved (linear, < 0.002) G:F. In Exp. 2, pigs (PIC 327 * 1050; = 576; initially 43.4 +/- 0.02 kg BW) were used to determine the effects of wheat source and particle size of pelleted diets on finishing pig growth performance and carcass characteristics. Pigs were randomly allotted to pens, and pens of pigs were balanced by initial BW and randomly allotted to 1 of 6 dietary treatments with 12 replications per treatment and 8 pigs/pen. The experimental diets used the same wheat-soybean meal formulation, with the 6 treatments using hard red winter or soft white winter wheat that were processed to 245, 465, and 693 MUm and 258, 402, and 710 MUm, respectively. All diets were pelleted. Overall, feeding hard red winter wheat increased ( < 0.05) ADG and ADFI when compared with soft white winter wheat. There was a tendency ( < 0.10) for a quadratic particle size * wheat source interaction for ADG, ADFI, and both DM and GE digestibility, as they were decreased for pigs fed 465-MUm hard red winter wheat and were greatest for pigs fed 402-MUm soft white winter wheat. There were no main or interactive effects of particle size or wheat source on carcass characteristics. In summary, fine grinding hard red winter wheat fed in meal form improved G:F and nutrient digestibility, whereas reducing particle size of wheat from approximately 700 to 250 MUm in pelleted diets did not influence growth or carcass traits. Finally, feeding hard red winter wheat improved ADG and ADFI compared with feeding soft white winter wheat. PMID- 27695776 TI - The effects of dietary supplementation of microencapsulated and the extract of seed on growth performance, immune functions, and serum biochemical parameters in broiler chickens. AB - This experiment was conducted to investigate the effects of microencapsulted (MEF) and the extract of seed (ECOS) on growth performance, immune functions, and serum biochemical parameters in broiler chickens. A total of 240 1-d-old male broilers were randomly allotted into 6 treatments with 8 replicates/treatment and 5 broilers in each cage. The dietary treatments included 1) a basal diet without antibiotic (group A), 2) the basal diet + 1 g MEF/kg diet (1 * 10 cfu/g MEF; group B), 3) the basal diet + 300 mg ECOS/kg diet (group C), 4) the basal diet + 300 mg ECOS/kg diet + 1 g MEF/kg diet (group D), 5) the basal diet + 500 mg ECOS/kg diet (group E), and 6) the basal diet + 500 mg ECOS/kg diet + 1 g MEF/kg diet (group F). The feeding experiment included 2 phases: the starter phase from Day 1 through 21 and the grower phase from Day 22 through 42. The results showed that a diet supplemented with MEF and ECOS had no significant effect on ADG, ADFI, feed conversion ratio, and average BW during the whole experimental period ( > 0.05), but group F showed an improving trend in growth performance. Serum IL 2, IgA, and IgG levels and spleen index were significantly affected by dietary treatment ( < 0.05). Serum IgA and IgG levels and spleen index in group F were significantly higher than in the group A ( < 0.05), and the IL-2 level was significantly decreased ( < 0.05) on Days 21 and 42. Compared with the group A, diets supplemented with MEF and ECOS can significantly decrease total cholesterol, low-density lipoprotein cholesterol, triglycerides, and blood urea nitrogen levels ( < 0.05) and increase the high-density lipoprotein cholesterol level on Days 21 and 42. Concentrations of serum biochemical parameters were significantly increased in group F ( < 0.05). In summary, the results indicated that dietary supplementation of MEF and/or ECOS had no significant effect on growth performance but significantly increased spleen index and the levels of serum IgA and IgG and improved serum lipid metabolism. The 1 g MEF/kg diet (1 * 10 cfu/g diet) plus 500 mg ECOS/kg diet was the optimum supplemental dose in this experiment. PMID- 27695777 TI - Genetic relationships between boar feed efficiency and sow piglet production, body condition score, and stayability in Norwegian Landrace pigs. AB - Both feed efficiency and sow production are economically important traits in pig breeding. One challenge in a maternal line such as Norwegian Landrace is to breed for highly feed efficient fattening pigs and, at the same time, produce sows with high daily feed intake to maintain their BCS in multiple parities. The aim of this study was to estimate genetic correlations among novel feed efficiency measurements on Norwegian Landrace boars and piglet production, stayability, and body condition in Norwegian Landrace sows. The feed efficiency measurements were lean meat and fat efficiency. These measurements were calculated using an extended residual feed intake model where total feed intake in the test period was the response variable and fat (kg) and lean meat (kg) on the carcass were included as both fixed and random regressions. The random regression coefficients that resulted from this model were breeding values, which represented the amount of feed used to produce an extra kilogram of lean meat and fat. The sow traits were stayability of the sow from first to second parity, BCS at weaning, litter weight at 3 wk, and total number of piglets born. All traits were recorded on first parity purebred Norwegian Landrace and analyzed using multivariate animal models. All genetic correlations between fat efficiency and sow traits were low. Significant genetic correlations were found only between fat efficiency and stayability (0.21 +/- 0.11) and between fat efficiency and total litter weight at 3 wk (0.21 +/- 0.10). The results indicate that selection for efficient deposition of fat could give poor stayability and lower litter weight at 3 wk in first parity sows. The genetic correlations between lean meat efficiency and sow traits were not significantly different from 0 and signified no genetic relationships between these traits. Selection for efficient deposition of lean meat should not affect the sow traits and is, therefore, beneficial. PMID- 27695778 TI - Net macromineral requirements in male and female Saanen goats. AB - These experiments estimated Ca, P, Mg, K, and Na requirements of intact male, castrated male, and female Saanen goats. Two experiments were performed: one to determine the net macromineral requirements for maintenance (Exp. 1) and another to determine net macromineral requirements for growth (Exp. 2). In Exp. 1, 75 goats (26 intact males, 25 castrated males, and 24 females) with initial BW (iBW) of 15.76 +/- 0.10 kg were used. These animals were divided in 2 groups: baseline animals and pair-fed animals. Twenty-one goats (8 intact males, 7 castrated males, and 6 females) were slaughtered (16.6 +/- 0.96 kg BW) at the beginning of the experiment to be used as the baseline group. The 54 remaining goats (18 intact males, 18 castrated males, and 18 females) were pair fed in 6 blocks of 3 goats per sex. The goats within each block were then randomly allocated to 1 of 3 levels of intake: ad libitum, restricted fed to 75% of the ad libitum intake, and restricted fed to 50% of ad libitum intake. When the animal fed ad libitum reached 31.2 +/- 0.58 kg BW, it and the other goats from the same block were slaughtered. The effects of sex and level of intake were evaluated in a split plot design, where sex was the main plot observation and level of intake was the subplot. Daily net macromineral requirements for maintenance did not differ among the sexes ( > 0.05), and the average values obtained were 35.4 mg Ca, 24.7 mg P, 2.5 mg Mg, 5.0 mg K, and 3.30 mg Na per kg BW?d. The net requirements for growth in Exp. 2 were obtained using 58 goats (20 intact males, 20 castrated males, and 18 females) with 15.8 +/- 0.11 kg iBW, all fed ad libitum. These animals were assigned in a completely randomized design and allocated in 3 slaughter weight groups: 16.6 +/- 0.96, 23.1 +/- 1.33, and 31.2 +/- 0.58 kg BW. The net Ca, P, and Mg requirements for growth were not different among the sexes ( > 0.05). There was a sex effect on net K and Na requirements for growth ( < 0.05). The net K requirements for growth (g/kg ADG) of intact males were greater ( = 0.03) and increased approximately 16%, whereas females and castrated males decreased approximately 11% as BW increased from 15 to 30 kg BW. The net Na requirements for growth (g/kg ADG) increased 9.5% for intact males and decreased 22% for females when the goats grew from 15 to 30 kg BW. Sex, therefore, affects net K and Na requirements for growth, but it does not affect net macromineral requirements for maintenance in Saanen goats. PMID- 27695779 TI - Deduction of a calcium ion circuit affecting rooster sperm in vitro. AB - Four premises for rooster sperm preservation were outlined previously. Understanding mitochondrial Ca cycling in terms of whole-cell Ca flux was one premise. The present work tested the hypothesis that sperm mitochondria can be damaged by intracellular as well as extracellular Ca. Sperm were washed by centrifugation through 12% (wt/vol) Sperm were washed by centrifugation through 12%(at/vol) Accudenz to procure sperm at a physiological concentration within a chemically-defined suspension. Five solutions were tested. Each solution contained 30 m glucose, and had an osmolality of 320 mmol/kg and a pH of 7.4. Washed sperm were diluted to 2.0 * 10 sperm/mL. Each replicate sperm suspension was cooled to 10 degrees C. Sperm mobility was measured after 1, 2, 4, 8, 12, and 24 h. Data were plotted as a function of time in each experiment. Function type was confirmed by lack of fit analysis. A parabola with a maximum at 3.7 h was observed when sperm were suspended in 205 m taurine buffered with 50 m tris[hydroxyl-methyl]methyl-2-amino-ethanesulfonic acid (TES). This effect was attributed to a Ca flux from the nuclear envelope into mitochondria. An exponential decay was observed when TES-buffered taurine contained 2 m Ca. This effect was attributed to mitochondrial Ca overload induced by uptake of extracellular Ca. Exponential decay also was observed when TES-buffered taurine contained a Ca chelator. This effect was attributed to a Ca flux from the nuclear envelope through mitochondria and then into an extracellular Ca sink. This possibility was supported by the response of sperm to thapsigargin. Specifically, inhibition of sarcoendoplasmic reticulum Ca-ATPase compromised sperm mobility relative to a buffer control. Finally, a 60 m phosphate buffer containing 2 m citrate yielded a linear relationship in contrast to the TES-buffered solutions tested. Sperm mobility after 24 h of storage in the phosphate buffer was 92% of that observed for prewashed sperm. The linear response was attributed to weak chelators providing resistance within a Ca circuit and thereby preventing mitochondrial Ca overload. Fertility, however, was compromised when hens were inseminated with mobile sperm recovered after either 8 or 24 h of storage at 10 degrees C. In conclusion, sperm cell Ca homeostasis was proven to be critical for maintaining sperm mobility in vitro, but mitochondrial Ca uptake is not the sole phenomenon that compromises sperm function during in vitro storage. PMID- 27695780 TI - Technical note: Impact of a molasses-based liquid feed supplement on the feed sorting behavior and growth of grain-fed veal calves. AB - This study was designed to determine the effect of adding a molasses-based liquid feed (LF) supplement to a high-grain mixed ration on the feed sorting behavior and growth of grain-fed veal calves. Twenty-four Holstein bull veal calves (90.2 +/- 2.6 d of age, weighing 137.5 +/- 16.9 kg) were split into groups of 4 and exposed, in a crossover design with 35-d periods, to each of 2 treatment diets: 1) control diet (76.0% high-moisture corn, 19.0% protein supplement, and 5.0% alfalfa/grass haylage) and 2) LF diet (68.4% corn, 17.1% protein supplement, 9.0% molasses-based LF, and 4.5% alfalfa/grass haylage). Diets were designed to support 1.5 kg/d of growth. Data were collected for the final 3 wk of each treatment period. Feed intakes were recorded daily and calves were weighed 2 times/wk. Feed samples of fresh feed and refusals were collected 3 times/wk for particle size analysis. The particle size separator had 3 screens (19, 8, and 1.18 mm) and a bottom pan, resulting in 4 fractions (long, medium, short, and fine). Sorting was calculated as the actual intake of each fraction expressed as a percent of its predicted intake. Calves tended ( = 0.08) to sort for long particles on the control diet (110.5%) and did not sort these particles on the LF diet (96.8%). Sorting for medium particles (102.6%) was similar ( = 0.9) across diets. Calves sorted against short particles on the LF diet (97.5%; = 0.04) but did not sort this fraction on the control diet (99.4%). Calves sorted against fine particles (79.3%) to a similar extent ( = 0.2) on both diets. Dry matter intake was similar across diets (6.1 kg/d; = 0.9), but day-to-day variability in DMI was greater (0.5 vs. 0.4 kg/d; = 0.04) when calves were fed the control compared with the LF diet. Calves on both diets had similar ADG (1.6 kg/d; = 0.8) as well as within-pen variability in ADG (0.4 kg/d; = 0.7). The feed-to-gain ratio was also similar between control and LF diets (4.3 vs. 3.9 kg DM/kg gain; = 0.4). The results suggest that supplementation of a molasses-based LF to high grain fattening veal calf diets can reduce variability in feed consumption, both within and across days.

Understanding stress responses in livestock may help refine management procedures and facilitate selection of stress-tolerant animals. In this study, behavioral (chute entry order, chute behavior, and exit velocity), physiological (serum cortisol), and biochemical (kinome) responses were evaluated in cattle ( = 20) subjected to three 5-min restraint periods with weekly intervals. Correlations among stress responses were assessed across all animals as well as for subgroups ( = 4) representing animals consistently displaying a high and low extreme of serum cortisol responses. Across all animals, entry order ( = 0.006) and exit velocity ( = 0.023) were positively correlated with serum cortisol; however, these correlations were not consistently reproducible for the high and low serum cortisol responders. Kinome profiling of peripheral blood mononuclear cells revealed distinct signaling events between the high and low cortisol responders. In particular, kinome profiling revealed significant differences in carbohydrate metabolism and apoptosis that were independently validated. Furthermore, changes in serum glucose levels provided a reliable, inexpensive indicator of serum cortisol levels and often had greater predictive value than cortisol for stress related behavioral responses. Serum cortisol levels displayed a pattern consistent with sensitization, whereas no habituation or sensitization was observed for serum glucose levels or behavioral responses. Collectively, this investigation provides insight into correlations among physiological, behavioral, and biochemical responses of cattle subjected to a brief restraint that may provide biomarkers for selection of stress-tolerant animals. PMID- 27695782 TI - Transcriptomic signature of high dietary organic selenium supplementation in sheep: A nutrigenomic insight using a custom microarray platform and gene set enrichment analysis. AB - The objective of this study was to investigate the effect of a high dietary Se supplementation on the whole transcriptome of sheep. A custom sheep whole transcriptome microarray, with more than 23,000 unique transcripts, was designed and then used to profile the global gene expression of sheep after feeding a high dietary supplementation of organic Se. Lactating crossbred ewes ( = 10; 3 to 4 yr of age and 55 to 65 kg BW) at late lactation (100 +/- 8 d in milk) were acclimated to indoor individual pen feeding of a basal control diet (0.40 mg Se/d, sodium selenite) for 4 wk. Sheep were then kept on a diet with an extra (high) supplementation of organic Se (1.45 mg Se/d as Sel-Plex; Alltech Biotechnology Pty Ltd, Dandenong, Victoria, Australia) for 40 d. Whole blood was collected at 2 time points (last day of the acclimatization period [T0] and after 40 d of the organic Se supplementation [T40]), and then total RNA was isolated and labeled for the subsequent microarray analysis. Significance Analysis of Microarrays, using the -statistic, of the microarray data (T40 versus T0) evidenced the up- and downregulation of 942 and 244 transcripts (false discovery rate < 0.05), respectively. Seven genes showed the same trend of expression (up- or downregulation) when tested by quantitative real-time PCR (qPCR) in a cross validation step. The microarray showed significant upregulation of the following selenoproteins at T40: selenium binding protein 1 (SELENBP1), selenoprotein W1 (SEPW1), glutathione peroxidase 3 (GPX3), and septin 8 (SEPT8). And the expression trends for SEPW1 and SEPT8 were validated using qPCR. Functional annotation of the differentially expressed genes showed the enrichment of several immune system-related biological processes (lymphocyte activation, cytokine binding, leukocyte activation, T cell differentiation, and B cell activation) and pathways (cytokine and interleukin signaling). Moreover, Gene Set Enrichment Analysis evidenced the enrichment of B and T cell receptors signaling pathways, with an enrichment score of 0.63 and 0.59, respectively. Overall, from a global gene expression (whole-transcriptome) point of view, short-term supplementation of a high dietary organic Se to Se-nondeficient sheep results in a transcriptomic signature that mainly reflects an induced immune system and a modulation of transcription effect. Also, the present study provides a custom whole transcriptome microarray platform that can be used in further global gene expression studies in the ovine species. PMID- 27695783 TI - Relationships between prenatal ewe traits, milk production, and preweaning performance of twin lambs. AB - There is limited information on factors affecting twin lamb growth before weaning, which limits the options available to farmers to actively manage lamb growth. Data from 2 multiyear experiments involving 402 twin-bearing Romney ewes were used to evaluate the effects of prenatal ewe traits (live weight at mating and set stocking and BCS at mating and set stocking) and combined twin lamb birth weight on ewe milk production and lamb growth from birth to weaning as well as the proportion of variation in twin lamb growth that could be explained by these variables. Additionally, the effect of accumulated ewe milk yield over a 42-d period (MY; Days 0 to 42) and accumulated milk components (protein, fat, and lactose) on twin lamb growth were investigated. The effects of prenatal variables on MY, birth weight, and combined twin lamb live weight gain from Day 0 to 42 (LWG) were inconsistent across the 2 experiments. In addition, prenatal ewe traits ( < 0.05) explained less than 30% of the variation in MY and lamb growth from birth to weaning in both experiments. Combined twin lamb birth weight was positively ( < 0.001) correlated with MY ( = 0.34 and = 0.43 in Exp. 1 and 2, respectively). Combined twin lamb LWG was dependent on ewe MY ( = 0.43 for Exp. 1 and = 0.30 for Exp. 2). Lactose, fat, and milk CP yields explained 47 and 42% of the variation in lamb LWG in Exp. 1 and 2, respectively. Lactose and milk CP yield positively affected ( < 0.05) LWG in Exp. 1 and 2, respectively. Fat yield had a positive relationship with LWG in Exp. 1 and a negative relationship with LWG in Exp. 2. In conclusion, the measured prenatal ewe traits had a minimal effect on milk yield and twin lamb growth to weaning. Milk yield and composition explained the greatest proportion of variation in LWG. This suggests that farmers should select ewes with higher milk yields to maximize twin lamb growth to weaning. However, less than 50% of the variation in LWG and weaning live weight was explained by the measured ewe and lamb parameters. Therefore, further studies are required to determine additional ewe or lamb variables that control variation in twin lamb growth. PMID- 27695784 TI - The effects of increasing supplementation of zinc-amino acid complex on growth performance, carcass characteristics, and inflammatory response of beef cattle fed ractopamine hydrochloride. AB - Forty-two Angus crossbred steers (380 +/- 5.3 kg) were enrolled in a finishing study to evaluate the influence of a supplemental Zn amino-acid complex (ZnAA; Availa-Zn) on performance and carcass characteristics of finishing steers in combination with ractopamine hydrochloride (RAC). Steers were stratified by BW into 7 pens of 6 steers each, and individual feed intake was measured. Steers were assigned to 1 of 4 treatments for 86 d (pre-RAC period): a dry-rolled corn based diet supplemented with 60 mg Zn/kg DM from ZnSO and no supplemental ZnAA (CON; analyzed 88 mg Zn/kg DM; = 6) or CON diet supplemented with 30 (Zn30; = 12), 60 (Zn60; = 12), or 90 (Zn90; = 11) mg Zn/kg DM from ZnAA. Day 86 BW and G:F displayed a quadratic tendency ( = 0.09) with Zn60 steers being greater than the other treatments. Plasma cyclic adenosine monophosphate tended to linearly increase with increasing ZnAA ( = 0.10). On d 88, 6 of 12 steers (one of the 2 pens) receiving supplemental ZnAA was randomly selected to be supplemented with RAC at 300 mg?steer?d for the final 28 d of the experiment (RAC period). This created 7 final treatments: CON: no supplemental ZnAA, no RAC ( = 5); Zn30: Zn30, no RAC ( = 5); Zn30R: Zn30 + RAC ( = 6); Zn60: Zn60, no RAC ( = 6); Zn60R: Zn60 + RAC ( = 6); Zn90: Zn90, no RAC ( = 5); and Zn90R: Zn90 + RAC ( = 6). During the RAC period, as supplemental ZnAA increased within RAC-supplemented treatments, there was a linear increase in final BW, ADG, and G:F ( < 0.05). However, there was no effect of supplemental ZnAA on BW, ADG, or G:F during this period in non RAC fed steers ( >= 0.44). Day 111 plasma Cu was increased, plasma Fe decreased, and leukocyte counts and serum interleukin-8 concentrations were greater ( < 0.05) in RAC-fed steers suggesting that RAC may elicit a mild inflammatory response. There was a tendency for increasing Zn supplementation to decrease plasma haptoglobin within RAC-fed steers ( = 0.07), suggesting that Zn may alter the inflammatory response. Overall, Zn60 improved growth performance during the pre-RAC period. Zinc supplemented as ZnAA appears to improve growth in combination with RAC supplementation, suggesting that Zn may enhance or support the biological function of RAC. Additionally, these results indicate that feeding RAC impacts trace mineral status, and potentially causes a non-specific inflammatory response, but further research is required to define this response. PMID- 27695785 TI - Dietary linseed oil with or without malate increases conjugated linoleic acid and oleic acid in milk fat and and gene expression in mammary gland and milk somatic cells of lactating goats. AB - Supplementary dietary plant oils have the potential to alter milk fatty acid composition in ruminants as a result of changes in the amount and kind of fatty acid precursors. We hypothesized that linseed oil in combination with malate (a key propionate precursor in the rumen) would increase ?9 unsaturated fatty acids and specific gene expression in somatic cells and mammary glands of lactating goats. Twelve lactating goats were used in a 3 * 3 Latin square design. Treatments included the basal diet (CON), the CON plus 4% linseed oil (LO), and the CON plus 4% linseed oil and 2% -malate (LOM). Relative to CON, the LO and LOM supplements increased the daily intake of palmitic (16:0), stearic (18:0), oleic (18:1-9), linoleic (18:2-6), alpha-linolenic (18:3-3), and gamma-linolenic acids (18:2-6); alpha-linolenic acid intake was increased over 9-fold, from 6.77 to over 51 g/d ( < 0.02). The LO and LOM supplements increased daily milk yield, milk fat yield, and milk fat percentage ( < 0.05). The LOM supplement also increased milk lactose percentage and daily yield ( = 0.03). Both the LO and LOM supplements increased plasma glucose and total cholesterol and decreased plasma beta-hydroxbutyrate concentrations ( = 0.03). The LO and LOM supplements increased concentrations of stearic acid; -vaccenic acid (TVA; 18:1-11); -9, -11 CLA; -10 -12 CLA; and alpha-linolenic acid in rumen fluid and increased the concentrations of oleic acid; TVA; -9, -11 CLA; -10, -12 CLA; and alpha-linolenic acid in plasma lipids and milk fat ( < 0.05). Conversely, the LO and LOM supplements decreased short- and medium-chain SFA, including lauric (12:0), myristic (14:0), and palmitic acids, in plasma and milk fat ( < 0.05). Relative mRNA levels for and () gene expression were increased in somatic cells and mammary gland tissue by LO and LOM ( < 0.05). We conclude that the higher intake and ruminal production of stearic acid promoted SCD gene expression in somatic cells and mammary tissue. Furthermore, milk somatic cells are a suitable substitute for documenting treatment effects of dietary oils on gene expression in goat mammary tissue. PMID- 27695786 TI - Requirement for digestible calcium by eleven- to twenty-five-kilogram pigs as determined by growth performance, bone ash concentration, calcium and phosphorus balances, and expression of genes involved in transport of calcium in intestinal and kidney cells. AB - Two experiments were conducted to determine the requirement for standardized total tract digestible (STTD) Ca by 11- to 25-kg pigs based on growth performance, bone ash, or Ca and P retention and to determine the effect of dietary Ca on expression of genes related to Ca transport in the jejunum and kidneys. Six diets were formulated to contain 0.36% STTD P and 0.32, 0.40, 0.48, 0.56, 0.64, or 0.72% STTD Ca by including increasing quantities of calcium carbonate in the diets at the expense of cornstarch. Two additional diets contained 0.72% STTD Ca and 0.33% or 0.40% STTD P to determine if 0.36% STTD P had negative effects on the Ca requirement. The same batch of all diets was used in both experiments. In Exp. 1, 256 pigs (11.39 +/- 1.21 kg initial BW) were randomly allotted to the 8 diets with 4 pigs per pen and 8 replicate pens per diet in a randomized complete block design. On the last day of the experiment, 1 pig from each pen was euthanized and the right femur and intestine and kidney samples were collected. Results indicated that ADG and G:F started to decline (linear and quadratic, < 0.05) at 0.54 and 0.50% STTD Ca, respectively. In contrast, bone ash increased (quadratic, < 0.05) as dietary Ca increased and reached a plateau indicating that the requirement for STTD Ca to maximize bone ash was 0.48%. Bone ash, but not ADG or G:F, increased (linear, < 0.01) as STTD increased in the diets. The mRNA expression of genes related to transcellular Ca transport decreased (linear, < 0.01) in the jejunum and in kidneys (linear and quadratic, < 0.01) as dietary Ca increased. In Exp. 2, 80 pigs (13.12 +/- 1.79 kg initial BW) were placed in metabolism crates and randomly allotted to the 8 diets with 10 replicate pigs per diet in a randomized complete block design. Fecal and urine samples were collected using the marker-to-marker approach. Results indicated that the requirement for STTD Ca to maximize Ca and P retention (g/d) was 0.60 and 0.49%, respectively. In conclusion, the STTD Ca requirement by 11- to 25-kg pigs to maximize bone ash was 0.48%; however, ADG and G:F declined if more than 0.54 or 0.50% STTD Ca, respectively, was fed, and the minimum concentration of Ca needed to maximize ADG and G:F could not be determined under the conditions of this experiment. Increasing dietary Ca decreased the mRNA expression of several genes related to transcellular Ca transport in the jejunum and the kidneys. PMID- 27695787 TI - Methane emissions changed nonlinearly with graded substitution of alfalfa silage with corn silage and corn grain in the diet of sheep and relation with rumen fermentation characteristics in vivo and in vitro. AB - Feeding grain and corn silage have been proposed as practices to reduce enteric methane (CH) emissions per unit of intake from ruminants, but the inclusion level required in the diet is normally not specified. The objectives of the current study were to determine the CH emission factor (g/kg DMI) of sheep fed alfalfa silage substituted with increasing levels of corn silage or corn grain at a fixed DMI level (2% of BW) and determine its relationship with rumen fermentation characteristics and microbial community composition and with in vitro fermentation characteristics of the same diets incubated using a standard laboratory method. Romney ewe hoggets (approximately 14 mo old; = 64) were randomly allocated to 8 dietary treatments, which included chaffed alfalfa silage alone or substituted with either 25, 50, 75 or 100% corn silage or 25, 50 or 65% rolled corn grain on a DM basis. After acclimatization to the diet, DMI and CH emissions were measured from individual sheep for 2 consecutive days in open circuit respiration chambers and a rumen sample was collected at 3 h after feeding. The same diets were also incubated in an automated in vitro gas production system for 48 h using rumen liquid of fistulated nonlactating dairy cows grazing pasture. Increasing the substitution of alfalfa silage with corn silage or corn grain in the diet of sheep resulted in a quadratic response ( < 0.01) in CH emissions per unit of DMI (CH/DMI) with either supplement. For both supplements, CH/DMI increased in mixtures of up to 50% supplement inclusion and then decreased with greater supplement inclusion, especially with corn grain inclusion, but the level did not fall below that for 100% alfalfa silage. The ratio of acetate + butyrate to propionate + valerate and the propionate proportion alone in rumen liquid were the strongest single predictors for CH/DMI in the overall data set and explained 37.1 and 32.5%, respectively, of the variation in CH/DMI. Methanogens of (21.1% of total methanogens; = 0.247) and (10.7% of total methanogens; = -0.411) clades had weak to moderate correlations with in vivo CH/DMI. There was a weak quadratic relationship ( < 0.35) between in vivo CH/DMI and the in vitro parameters of gas and CH production and total VFA, whereas there was a moderate relationship ( = -0.50) between in vivo CH/estimated rumen degradable carbohydrates and in vitro CH/DM. In conclusion, CH/DMI changed in a nonlinear fashion with increasing supplement inclusion in the alfalfa forage diet when fed at 2% of BW to sheep; however, implications on predicting its influence on greenhouse gas emissions per unit of animal product, for whole farm emissions in life cycle analysis or total national emissions in the national inventories, should be determined. PMID- 27695788 TI - Cloning of oligopeptide transport carrier PepT1 and comparative analysis of PepT1 messenger ribonucleic acid expression in response to dietary nitrogen levels in yak () and indigenous cattle () on the Qinghai-Tibetan plateau. AB - The gastrointestinal lumen can directly absorb all di- and tripeptide protein degradation products, and oligopeptide absorption depends on the specific peptide transport carriers, which are located in gastrointestinal epithelial cells on the brush border membrane. Yak () use N more efficiently than cattle do, which implies that yak have a specific mechanism of nonprotein utilization including a peptide absorption mechanism. However, this mechanism has not been clarified. Our objective was to explore whether yak possess any adaptive mechanisms of peptide absorption to survive in the harsh foraging environment of the Qinghai-Tibetan plateau. Twelve castrated males of each of 2 genotypes, yak () and indigenous cattle (), were fed diets of various N levels. The yak PepT1 (yPepT1) cDNA was cloned in omasum epithelial tissue. Our results showed that the full-length yPepT1 cDNA contains 2,805 bp, and a 2,121-bp open reading frame encodes a putative protein of 707 AA residues. The yPepT1 AA sequence identified 5 putative extracellular N-glycosylation sites (Asn, Asn, Asn, Asn, and Asn), 2 putative intracellular protein kinase A sites (Ser and Thr), and 3 intracellular putative protein kinase C sites (Ser, Ser, and Ser). The yPepT1 AA sequence was 99, 95, 86, and 83% identical to PepT1 from cattle (), sheep (), pigs (), and humans (), respectively. The relative PepT1 mRNA expression for indigenous cattle was greater than yak in the rumen, omasum, duodenum, ileum, and liver ( < 0.001); however, it was lower in jejunum tissue ( < 0.01). The relative PepT1 mRNA expression in response to increasing dietary N for both genotypes were linear in the rumen and jejunum ( < 0.10); quadratic or cubic in the reticulum ( < 0.01); linear or quadratic in the duodenum, ileum, and liver ( <= 0.01); and linear, quadratic, or cubic in the omasum ( < 0.001). Moreover, there were significant interactions between genotype and dietary N in rumen, reticulum, omasum, duodenum, jejunum, ileum, and liver tissues. In conclusion, the PepT1 profile and expression in gastrointestinal epithelial cells of yak varied from those of cattle, implying that yak have evolved a peptide transport mechanism to adapt the environment of the Qinghai-Tibetan plateau. PMID- 27695789 TI - Subacute ruminal acidosis reduces sperm quality in beef bulls. AB - Breeding bulls are commonly fed high-energy diets, which may induce subacute ruminal acidosis (SARA). In this experiment, 8 Santa Gertrudis bulls (age 20 +/- 6 mo) were used to evaluate the extent and duration of effects of SARA on semen quality and the associated changes in circulating hormones and metabolites. The bulls were relocated and fed in yards with unrestricted access to hay and daily individual concentrate feeding for 125 d before SARA challenge. Semen was collected and assessed at 14-d intervals before the challenge to ensure acclimatization and the attainment of a stable spermiogram. The challenge treatments consisted of either a single oral dose of oligofructose (OFF; 6.5 g/kg BW) or an equivalent sham dose of water (Control). Locomotion, behavior, respiratory rate, and cardiovascular and gastrointestinal function were intensively monitored during the 24-h challenge period. Rumen fluid samples were retained for VFA, ammonia, and lactate analysis. After the challenge, semen was then collected every third day for a period of 7 wk and then once weekly until 12 wk, with associated blood collection for FSH, testosterone, inhibin, and cortisol assay. Percent normal sperm decreased in bulls dosed with OFF after the challenge period ( < 0.05) and continued to remain lower on completion of the study at 88 d after challenge. There was a corresponding increase in sperm defects commencing from 16 d after challenge. These included proximal cytoplasmic droplets ( < 0.001), distal reflex midpieces ( = 0.01), and vacuole and teratoid heads ( < 0.001). Changes in semen quality after challenge were associated with lower serum testosterone ( < 0.001) and FSH ( < 0.05). Serum cortisol in OFF bulls tended to be greater ( = 0.07) at 7 d after challenge. This study shows that SARA challenge causes a reduction in sperm quality sufficient to preclude bulls from sale as single sire breeding animals 3 mo after the event occurred. PMID- 27695790 TI - Heat stress affects the apparent and standardized ileal digestibilities of amino acids in growing pigs. AB - Heat stress (HS) appears to impair the pig's small intestine digestive and absorptive capacities and, therefore, may affect the AA digestibilities. A crossover-designed experiment was conducted utilizing two 7-d periods with 8 pigs (30.8 kg initial BW) surgically fitted with T-type cannulas at the terminal ileum to analyze the effect of HS on both apparent (AID) and standardized (SID) ileal digestibility of AA in pigs fed a wheat-soybean meal diet. Subcutaneous skin and ileal lumen temperatures were continuously monitored in 15-min intervals during the entire experiment. After recovery from surgery, all pigs were adapted to the diet and trained to consume the same amount of feed twice a day for 5 d in thermal-neutral (TN) conditions (22 degrees C +/- 2 degrees C). Following adaptation, pigs were divided into 2 groups (4 pigs each); 1 remained in TN conditions, and the other group was exposed to natural HS (24 degrees C to 45 degrees C) for 7 d (period 1). In period 2, the 2 groups switched environments. Ileal digesta were continuously collected for 12 h, starting at 0700 h, on d 6 and 7 of each period. Chromic oxide was used as an indicator of intestinal digesta flow. The subcutaneous and the ileal temperatures were increased between 1.3 degrees C and 1.6 degrees C in HS compared to TN pigs ( < 0.001). The AID of AA (%) for the TN and HS pigs were Arg, 90.6, 88.1; His, 88.7, 85.9; Ile, 84.8, 83.9; Leu, 86.9, 84.1; Lys, 86.8, 86.2; Met, 89.8, 89.1; Phe, 86.0, 84.8; Thr, 76.7, 74.3; and Val, 82.8, 81.7, respectively. The SID (%) of AA for the TN and HS pigs were Arg, 94.0, 92.0; His, 92.5, 90.2; Ile, 89.5, 88.1; Leu, 90.1, 88.6; Lys, 91.0, 90.1; Met, 94.4, 93.6; Phe, 90.4, 88.9; Thr, 86.0, 83.7; and Val, 88.1, 86.5, respectively. The AID of Arg, His, and Leu was lower ( < 0.01) in HS pigs, and the SID of Arg and His was also lower in HS pigs. Neither the AID nor the SID of the remaining essential AA was affected by HS. In summary, the digestibility of essential AA is differentially affected in pigs exposed to natural HS, and thus, special attention should be given to Arg and His when formulating diets for growing pigs under HS conditions. PMID- 27695791 TI - Genetic variation for farrowing rate in pigs in response to change in photoperiod and ambient temperature. AB - Seasonal infertility is often observed as anestrus and a lower conception rate resulting in a reduced farrowing rate (FR) during late summer and early autumn. This is often regarded as an effect of heat stress; however, we observed a reduction in the FR of sows even after correcting for ambient temperature in our data. Therefore, we added change in photoperiod in the analysis of FR considering its effect on sow fertility. Change in photoperiod was modeled using the cosine of the day of first insemination within a year. On an average, the FR decreased by 2% during early autumn with decreasing daily photoperiod compared with early summer with almost no change in daily photoperiod. It declined 0.2% per degree Celsius of ambient temperature above 19.2 degrees C. This result is a step forward in disentangling the 2 environmental components responsible for seasonal infertility. Our next aim was to estimate the magnitude of genetic variation in FR in response to change in photoperiod and ambient temperature to explore opportunities for selecting pigs to have a constant FR throughout the year. We used reaction norm models to estimate additive genetic variation in response to change in photoperiod and ambient temperature. The results revealed a larger genetic variation at stressful environments when daily photoperiod decreased and ambient temperatures increased above 19.2 degrees C compared with neutral environments. Genetic correlations between stressful environments and nonstressful environments ranged from 0.90 (+/-0.03) to 0.46 (+/-0.13) depending on the severity of the stress, indicating changes in expression of FR depending on the environment. The genetic correlation between responses of pigs to changes in photoperiod and to those in ambient temperature were positive, indicating that pigs tolerant to decreasing daily photoperiod are also tolerant to high ambient temperatures. Therefore, selection for tolerance to decreasing daily photoperiod should also increase tolerance to high ambient temperatures or vice versa. PMID- 27695792 TI - Supplementation of organic and inorganic selenium to late gestation and early lactation beef cows effect on cow and preweaning calf performance. AB - Angus * Simmental cows ( = 48; BW = 595 +/- 17.4 kg, BCS = 5.26 +/- 0.05, and age = 2.3 +/- 0.07 yr), pregnant with male fetuses, were used to determine the effect of Se source during the last 80 d of gestation and first 108 d of lactation on cow and calf performance. At 203 d in gestation, cows were blocked by BW, breed composition, age, and calf sire and randomly allotted to organic Se, inorganic Se, or no Se treatments. Diets contained corn silage, corn stover, haylage, dried distillers' grains with solubles, and minerals and were formulated to contain 10.4% CP and 0.90 Mcal/kg NEg during gestation and 12.1% CP and 1.01 Mcal/kg NEg during lactation. Diets were fed daily as a total mixed ration and none, 3 mg/d Se as sodium selenite, or 3 mg/d Se as Sel-Plex were top-dressed daily. At 68 d postpartum (DPP), milk production was calculated using the weigh-suckle-weigh procedure and a milk sample was collected to determine composition. At 108 DPP, cow-calf pairs were commingled until weaning at 210 DPP. Cow BW and BCS ( >= 0.56) did not differ between treatments at any time point during the study. Milk production, milk fat, and total solids ( >= 0.38) did not differ among treatments. Milk protein tended to increase in cows fed inorganic Se compared with cows fed organic Se ( = 0.07) and milk lactose tended to be greatest in cows fed organic Se ( = 0.10). Conception to AI and overall pregnancy rates did not differ between treatments ( >= 0.39). Calf weights and ADG did not differ through 108 DPP ( >= 0.77) or for the preweaning period ( >= 0.33). Plasma Se concentration was adequate for all cows and did not differ among treatments for cows ( >= 0.37) or calves ( >= 0.90). Liver Se concentrations in cows fed inorganic or organic Se were greater than in control cows ( < 0.01). Longissimus muscles biopsies taken from progeny at 108 DPP also did not differ between treatments ( = 0.45). In conclusion, dietary Se source did not affect cow performance, milk production, or reproductive efficiency. Organic Se decreased milk protein and increased milk lactose but did not alter preweaning performance of progeny from Se-adequate cows. PMID- 27695793 TI - Are all piglets born lightweight alike? Morphological measurements as predictors of postnatal performance. AB - Birth weight (BiW) of pigs is a commonly used predictor of postnatal performance; however, it has been suggested that morphological measurements may be more reflective of the intrauterine environment and thus better predictors of postnatal growth. The aim of this study was to determine 1) whether morphological measurements, including ponderal index (PI), body mass index (BMI), and abdominal circumference (AC), could be used as predictors of postnatal performance and 2) if so, would they be better predictors than BiW and 3) would the same predictors apply to pigs of different BiW at different stages of their growth? Morphological measurements, BiW, and BW at d 28 and 70 were available for 731 pigs from experiments conducted over a 2-yr period. A series of linear models was used to determine predictors that affected growth performance from birth to d 28 and from d 28 to 70. For both light (LBiW; <=1.25 kg) and normal BiW pigs (NBiW; 1.60 to 2.00 kg), BiW was not the best predictor of performance ( > 0.05); different variables for the growth periods considered applied to pigs with different BiW. For LBiW pigs BMI ( < 0.001) and AC ( = 0.0202) were the best predictors for d 1 to 28, and AC ( = 0.0317) and PI ( = 0.0450) were the best predictors from d 28 to 70, with pigs with a larger AC and higher PI/BMI more likely to have higher ADG pre- or postweaning. In contrast, the best predictor variables for NBiW pigs were AC ( = 0.0482) for d 1 to 28 and crown-rump length (CRL; = 0.0138) for d 28 to 70. Focusing on LBiW pigs with low ADG, BMI was the best predictor ( < 0.05) of growth for pre and postweaning, whereas for LBiW pigs with high ADG the best predictors were AC ( = 0.00132) from d 1 to 28 and BiW ( = 0.00601) from d 28 to 70, with increasing BMI, AC, and BiW associated with greater ADG. For NBiW pigs with high preweaning ADG, the best predictor consisted solely of AC ( 0.0210), but no morphological predictor variables were significant for NBiW pigs with low preweaning ADG. For d 28 to 70, the best predictor for NBiW pigs with low ADG was CRL ( = 0.0171), but for high ADG no predictor variables were significant. The present study showed that the morphology of piglets is more important than BiW when predicting the postnatal growth of pigs; however, which measurement is the most important depends on both the BiW and stage of growth. For small-sized pigs, these morphological measures may be considered as a decision-making tool by farmers when trying to identify potential poor performers.

AB - The objective of this study was to assess the nutritional value of barley grain differing in diastatic power (DP; high vs. low; a malt trait) and processing index (PI; 75 vs. 85). One hundred sixty Angus * Hereford crossbred yearling steers (467 +/- 38 kg; 144 intact and 16 rumen cannulated) were used in a complete randomized 2 * 2 factorial experiment. Steers were assigned to 16 pens, 8 of which were equipped with the GrowSafe system to measure individual feed intake. Cannulated steers (2 per pen) were randomly assigned to the 8 GrowSafe pens. Diets consisted of high- or low-DP barley grain (80.0% of diet DM) processed to an index of either 75 or 85% (PI-75 and PI-85, respectively). Ruminal pH in cannulated steers was measured over four 5-d periods using indwelling electrodes. Fecal samples were collected every 28 d from the rectum of each steer to assess digestibility using AIA as a marker. No differences ( > 0.10) in rumen pH were observed among cattle as measured by the indwelling pH meters. However, lower ( < 0.05) rumen pH was observed for steers fed low- as opposed to high-DP barley in rumen samples collected just prior to feeding and measured in the laboratory. Intake of DM and OM were not affected ( >= 0.24) by DP but were lower ( < 0.01) with more severe processing (PI-75 vs. PI-85). Low-DP barley tended to exhibit higher ( = 0.09) total tract DM digestibility than high DP barley. Steers fed PI-75 barley also had higher ( = 0.06) G:F and NEg. Digestibility of DM, OM, CP, NDF, and starch was higher ( < 0.05) for PI-75 barley than for PI-85 barley. Low-DP barley increased ( < 0.05) carcass dressing percentage by 0.5% compared with high-DP barley, with a lower PI tending to increase ( = 0.06) rib eye area. Compared with steers fed high-DP diets, steers fed low-DP diets had more ( = 0.01) total (41.7 vs. 19.4%) and severe liver abscesses (22.2 vs. 9.7%). Results suggest that although low-DP barley increased liver abscesses, differences in DP did not alter digestion or growth performance but low-DP barley did improve dressing percentage. Barley with different DP responded similarly to processing, with more intensive processing (PI-75) of barley improving starch digestion, feed efficiency, and NEg without negatively affecting rumen pH. PMID- 27695796 TI - Erratum. PMID- 27695795 TI - Comparison of energy rationing systems for late gestation ewes: Impacts on ewe and lamb performance. AB - The objectives of this study were 1) to compare the effects of a ME () or a NE () system for rationing ewes during late gestation on ewe and progeny performance and 2) to investigate incremental increases in NE allocation above 100% of recommendation during late gestation on ewe and progeny performance. Fifty-two twin-bearing ewes ( = 13 per treatment) were rationed to either 100% of recommended ME requirements (100% ME) or 100, 110, or 120% of recommended NE requirements (100% NE, 110% NE, and 120% NE) from d 112 of gestation to parturition. Mean energy intake, measured as ME and NE, from Day 112 of gestation to parturition was higher in all NE treatments compared with 100% ME ewes ( = 0.01). Ewes offered the 3 NE treatments had a higher live weight at parturition compared with 100% ME ewes ( = 0.02), with 100% NE and 120% NE ewes still being heavier than 100% ME ewes at 35 d postpartum ( = 0.02). Increasing NE allowance resulted in a linear decrease in the level of BCS loss prepartum ( = 0.01) and a linear increase in the level of BCS loss postpartum ( = 0.01). There was no difference observed between any of the treatments in total colostrum produced to 18 h postpartum ( = 0.29) or in total colostrum intake to 18 h postpartum ( = 0.27). Increasing maternal NE allowance led to a linear increase in lamb serum IgG concentration at 24 h postpartum ( = 0.03). The estimated milk production of 120% NE ewes tended to be higher than all other treatments at wk 6 of lactation ( = 0.08). Colostral SFA levels from 100% ME ewes was lower than that of all 3 NE treatments ( = 0.01), and unsaturated fatty acid (UFA) levels in colostrum of the 100% ME ewes were lower than those of the 100% NE ewes ( = 0.01). Cumulative levels of milk SFA, UFA, and MUFA did not differ between treatments ( = 0.19). Lamb growth rates during the first 5 wk postpartum were unaffected by treatment ( = 0.18) as were days to slaughter ( = 0.34). It can be concluded that both ME and NE systems used in this study are appropriate for formulating ewe diets during late gestation. Increasing NE allocation above 100% altered the pattern of body reserve mobilization during late gestation and early lactation without observed variations in lamb performance during this time. PMID- 27695797 TI - Assessing cow-calf welfare. Part 1: Benchmarking beef cow health and behavior, handling; and management, facilities, and producer perspectives. AB - Assessment programs are one way beef producers communicate information about animal welfare to retailers and the public. Programs that monitor cattle through the production cycle (e.g., the Global Animal Partnership) or at individual stages (e.g., slaughter; the North American Meat Institute) exist, but to date, there is no assessment program addressing welfare specifically in the cow-calf sector. The objectives of this study were to measure cow-calf health and handling welfare outcomes and gather management, facility, and producer perspective information to 1) describe current practices and 2) inform assessment design. A welfare assessment, designed using features of similar beef and dairy programs, was conducted on 30 California ranches that varied in size (mean 1,051 cows [SD 1,849], range 28 to 10,000 cows) and location within the state. Cattle health and behavior and stockperson handling were measured during a routine procedure (e.g., pregnancy checks) on breeding females ( = 3,065). Management and producer perspectives were evaluated through an interview, and facility features were recorded at the chute and water access points. Cattle health problems were rare and seen only on specific ranches (e.g., prevalence of lame cattle: mean 1.3% [SD 1.5], range 0 to 7.1%). Cattle behavior and stockperson handling varied between ranches (e.g., cattle balking: mean 22.0% [SD 21.9], range 1.6 to 78.3%; electric prod use: mean 23.5 [SD 21.5], range 0 to 73.0%). Although some management and facility characteristics were shared by most (e.g., all ranches castrated bull calves; 86% used alleyways with an anti-back gate), other aspects varied (e.g., weaning age: mean 8.2 mo [SD 1.4], range 6 to 11 mo; 43% used shade cover over chute). Most producers shared similar perspectives toward their herd health management plan, but their responses varied when asked to evaluate an animal's pain experience. In terms of assessment design, there were challenges with feasibility (e.g., scheduling a ranch visit on a day cattle were processed was difficult), validity (e.g., cattle may back up calmly to adjust posture or quickly in response to an aggressive handler; without this context, the welfare implications of this behavior are unclear), and comparability (e.g., an explicit animal observation period needed to be defined to make comparisons across ranches). Future assessment programs should consider these qualities when selecting measures to evaluate welfare.

PMID- 27695799 TI - Evaluating dietary adjustment and collection times for total tract digestibility of Ca, P, and the essential microminerals with grower swine. AB - An experiment was conducted to determine 1) the length of time necessary for grower pigs to adjust to a new diet and 2) the consistency in excretion of urine and feces in 4 consecutive 5-d collection periods. The total tract excretion and digestibility values for Ca, P, and the essential microminerals were evaluated. The experiment was conducted in 6 replicates as a randomized complete block design. Pigs were fed a pretest diet from 20 to 40 kg BW that met the requirements. At 40 kg, 12 barrows were allotted to stainless-steel metabolism crates, where they continued being fed the pretest diet for a 7-d period for adjustment purposes. Treatment diets were then fed for the following 20-d period in four 5-d intervals. Treatment diets were a corn-soybean meal mixture and contained either 1) reduced Ca and P levels and no added microminerals (LOW) or 2) a diet with elevated Ca and P levels and supplemental microminerals that exceeded the pig's requirements (HIGH). The study collected urine and feces. Markers were added to the ration at the start of each period to distinguish between test intervals. Feces and urine were collected daily, frozen, and composited for each period. Analysis of diets and excrement was conducted using inductively coupled plasma mass spectrometry technology. In all cases, the excreted minerals and digestibility values were greater ( < 0.01) for the macrominerals when the HIGH diet was fed, whereas the digestibility values for the microminerals were often lower when the HIGH diet was fed. The macrominerals Ca and P both had consistent urine and fecal values for each of the final 3 collection periods within diet. The micromineral values were generally consistent for each 5-d collection period but varied between periods for several microminerals. These results indicate that a 5-d adjustment period was adequate for pigs to adjust to the treatment diets. A 5-d collection period was adequate for Ca and P, but the micromineral excretion and digestibility values were more variable, and a collection period of 10 d might be warranted. The results also indicated that the innate microminerals had a higher digestibility and bioavailability than thought previously and their digestibility is greater than that of inorganic microminerals. Thus, these results indicate that the innate microminerals should be an important factor in establishing the micromineral requirements for growing pigs. PMID- 27695800 TI - Chemical composition, true nutrient digestibility, and true metabolizable energy of novel pet food protein sources using the precision-fed cecectomized rooster assay. AB - A wide variety of animal protein-based ingredients is commonly used in the pet food products. The raw ingredients and processing procedures used may greatly affect protein quality. Testing the quality of alternative protein sources is necessary and contributes to the sustainability of pet foods. The objective of this study was to test the chemical composition of 8 protein sources intended for use in dog and cat foods (calamari meal, pork peptone, alligator meal, lamb meal, venison meal, chicken meal, and 2 duck meals), and evaluate their true nutrient digestibility and nitrogen-corrected true ME (TMEn) using the precision-fed cecectomized rooster assay. Calamari meal and pork peptone had lower ash (4.4 and 3.6% of DM, respectively) but greater CP (88.1 and 80.5% of DM, respectively) and either greater or similar GE (5.6 and 5.3 kcal/g of DM, respectively) compared with alligator, lamb, venison, chicken, and duck meals (11.8 to 24.5% ash, 58.7 to 65.9% CP, and 4.6 to 5.3 kcal GE/g). Acid-hydrolyzed fat (AHF) was lower in calamari meal (8.7% of DM) compared with the other proteins tested (15.5-22.1% of DM). True nutrient digestibility was variable among the protein sources (52 to 79% of DM, 60 to 83% of OM, 78 to 92% of AHF, and 70 to 89% of GE) with pork peptone having the highest DM, AHF, and GE digestibility and calamari meal having the highest OM digestibility. True indispensable AA digestibility was highest for calamari meal, with all AA having a digestibility greater than 90%. Except for histidine, all indispensable AA had a digestibility over 85% for pork peptone. In contrast, true indispensable AA digestibility was lowest for lamb meal, with histidine having digestibility less than 70% and the other entire indispensable AA having digestibility between 72 and 88%. The TMEn of calamari meal (4.82 kcal/g DM and 86.9% of GE) was greater ( < 0.05) than the other protein sources. The lamb meal had the lowest TMEn value (3.12 kcal/g DM and 66.9% of GE), with others being intermediate (3.46-4.09 kcal/g DM and 71.2-77.9% of GE). This study demonstrates the considerable variability that exists not only in the chemical composition but also in the true nutrient digestibility among protein sources intended for use in dog and cat foods and justifies further in vivo testing of novel protein sources. PMID- 27695801 TI - Effects of general anesthesia with ketamine in combination with the neuroleptic sedatives xylazine or azaperone on plasma metabolites and hormones in pigs. AB - Physiological research with swine often includes sedation or general anesthesia (GA), which may influence the basal physiological responses of experimental animals and may have the potential to confound or interfere with the effects of experimental factors of interest. Using 6 adult female pigs, we investigated whether selected plasma metabolites and hormones are influenced by GA induced with ketamine (K) and 2 neuroleptic sedatives, namely azaperone (A) and xylazine (X). Fasted pigs rotationally received either no drug, a single intravenous administration of A or X, or A or X combined with ketamine (AK or XK, respectively), and plasma concentrations of glucose, lactate, non-esterified fatty acids (NEFA), triglycerides (TG), glucagon, insulin, and cortisol were determined for a 5-h period following administration. Azaperone and X induced deep sedation, whereas AK and XK induced GA. Overall, the average plasma glucose concentrations were increased by A and X, with the latter exerting a stronger effect that was also associated with hypoinsulinemia ( < 0.05). Time-dependent effects indicated a more rapid increase in glucose concentration due to X or XK than AK. Plasma NEFA concentrations were elevated by A and AK and to a lesser extent by X and XK ( < 0.05). Plasma lactate and TG levels were elevated by A and AK and remained unaffected by X or XK. Plasma cortisol concentrations were elevated ( < 0.05) by X and XK and even more so with a single administration of A ( < 0.05), while the combined effect of A with ketamine resulted in the highest cortisol concentrations ( < 0.05). Our data suggest that the effects of azaperone are mediated by cortisol but less so for xylazine, which also indicates that azaperone elicits a stronger stress response in pigs. Xylazine probably induces long-lasting, fasting-state hyperglycemia through the stimulation of hepatic glucose production associated with hypoinsulinemia. A discriminant analysis based on the variation in all of the measured metabolites and hormones, collectively, indicated that ketamine induced no additional effect on the overall physiological response patterns than that of the individual sedatives. In conclusion, the neuroleptic sedatives azaperone, and to a lesser extent, xylazine, acutely affect the metabolism of pigs, so primary metabolic readouts obtained under these drugs may be confounded. PMID- 27695802 TI - INVITED REVIEW: Inhibitors of myostatin as methods of enhancing muscle growth and development. AB - With the increasing demand for affordable, high-quality meat, livestock and poultry producers must continually find ways to maximize muscle growth in their animals without compromising palatability of the meat products. Muscle mass relies on myoblast proliferation during prenatal or prehatch stages and fiber hypertrophy through protein synthesis and nuclei donation by satellite cells after birth or hatch. Therefore, understanding the cellular and molecular mechanisms of myogenesis and muscle development is of great interest. Myostatin is a well-known negative regulator of muscle growth and development that inhibits proliferation and differentiation in myogenic cells as well as protein synthesis in existing muscle fibers. In this review, various inhibitors of myostatin activity or signaling are examined that may be used in animal agriculture for enhancing muscle growth. Myostatin inhibitors are relevant as potential therapies for muscle-wasting diseases and muscle weakness in humans and animals. Currently, there are no commercial myostatin inhibitors for agriculture or biomedical purposes because the safest and most effective option has yet to be identified. Further investigation of myostatin inhibitors and administration strategies may revolutionize animal production and the medical field. PMID- 27695803 TI - Digestibility of energy, amino acids, and phosphorus in a novel source of soy protein concentrate and in soybean meal fed to growing pigs. AB - Three experiments were conducted to determine standardized ileal digestibility (SID) of CP and AA, DE and ME, and apparent total tract digestibility (ATTD) and standardized total tract digestibility (STTD) of P in a new source of soy protein concentrate (SPC) and in soybean meal (SBM). In Exp. 1, 9 barrows (initial BW: 13.08 +/- 1.98 kg) were prepared with a T-cannula in the distal ileum and allotted to a triplicated 3 * 3 Latin square design with 3 diets and 3 periods. A nitrogen-free diet and 2 diets that contained corn starch and SPC or SBM as the sole source of CP and AA were formulated. Each period lasted 7 d, and ileal digesta were collected on d 6 and 7 of each period. The SID for Ile, Leu, Phe, Pro, and Tyr was greater ( < 0.05) in SPC than in SBM, but for CP and all other AA, no difference between SPC and SBM was observed. In Exp. 2, 24 barrows (initial BW: 13.94 +/- 1.34 kg) were housed individually in metabolism crates and randomly allotted to 1 of 3 diets. A corn-based diet (96.9% corn) and 2 diets that contained corn and SPC or corn and SBM were formulated. Each diet was fed to 8 pigs. Feces and urine samples were collected using the marker to marker method with 5-d adaptation and 5-d collection periods. The DE and ME in SPC and SBM were calculated using the difference procedure. Results indicated that the ATTD of GE was lower ( < 0.05) in SBM than in corn and the DE and ME in SPC were greater ( < 0.01) than in corn and SBM. In Exp. 3, 40 barrows (initial BW: 14.12 +/- 2.08 kg) were placed in metabolism crates and allotted to 4 diets in a randomized complete block design with 10 pigs per diet. Two diets were based on SPC or SBM as the sole source of P. Two additional diets were formulated by adding microbial phytase to diets that were otherwise similar to the 2 initial diets. Feces were collected for 5 d after a 5-d adaptation period and values for ATTD and STTD of P were calculated. No differences were observed in ATTD and STTD of P between SPC and SBM, but the ATTD and STTD of P of both SPC and SBM were greater ( < 0.01) if microbial phytase was added to the diets. In conclusion, the concentrations of DE and ME are greater in SPC than in SBM, but the SID of most AA and the STTD of P are not different between SPC and SBM. PMID- 27695804 TI - Growth performance, feed digestibility, body composition, and feeding behavior of high- and low-residual feed intake fat-tailed lambs under moderate feed restriction. AB - Two experiments were conducted to evaluate the effect of moderate feed restriction on productivity of lambs classified on the basis of phenotypic expression of residual feed intake (RFI). In Exp. 1, 58 fat-tailed Kurdi ram lambs (32.1 +/- 4.2 kg BW) were individually fed, ad libitum, a pelleted diet (35% alfalfa hay and 65% concentrate). Feed intake and ADG were determined for a 6-wk period and 3 feed efficiency measures including RFI, G:F, and partial efficiency of maintenance (PEM) were calculated. The lambs were sorted based on RFI and the 16 highest RFI (RFI >= mean + 0.5 SD) and 16 lowest RFI (RFI <= mean 0.5 SD) lambs were subjected to body composition (BC) and DM digestibility (DMD) analysis. Feeding behavior traits (FB) were also evaluated for 24 h using a regular 5-min interval observation method. The high- and low-RFI lambs (14 lambs/RFI group) so classified in Exp. 1 were used in Exp. 2. Half of the lambs in each RFI group were randomly selected to be fed ad libitum or 85% of ad libitum (restricted feeding), which resulted in 4 experimental groups: 1) ad libitum high-RFI, 2) feed restricted high-RFI, 3) ad libitum low-RFI, and 4) feed restricted low-RFI. The lambs were fed the same diet as Exp. 1, and growth efficiency during a 6-wk test period as well as BC, DMD, and FB were also determined in Exp. 2. In Exp. 1, the low-RFI lambs consumed 14% ( < 0.01) less feed than high-RFI lambs. Differences were also observed between high- and low RFI groups for G:F ( = 0.01), RFI ( < 0.01), and PEM ( < 0.01) in Exp. 1, but no differences were detected between high- and low-RFI lambs for ADG ( = 0.79), DMD ( = 0.42), BC ( > 0.72), and FB ( > 0.24). In Exp.2, the restriction feeding regime negatively affected ADG ( < 0.01) and G:F ( = 0.02) in low-RFI lambs, whereas G:F ( = 0.02) and PEM ( < 0.01) were improved in high-RFI lambs under the feed restriction condition. No effects of feed restriction on DMD ( = 0.87) and BC ( > 0.05) were observed. The lambs fed at the restricted level of intake presented a greater time ( < 0.01) and rate ( = 0.01) of eating than those fed ad libitum. Although bunk visits and feeding events were decreased ( < 0.01) with feed restriction, no interaction ( > 0.05) was detected between RFI phenotype and feeding regime for FB. In summary, feeding high-RFI lambs at 85% of ad libitum level improved G:F with no effect on ADG, whereas growth performance was reduced by feeding low-RFI lambs at 85% of ad libitum. However, these changes in feed efficiency were not related to DMD, BC, or FB. PMID- 27695805 TI - Comparison of visual and electronic devices for individual identification of dromedary camels under different farming conditions. AB - The camel industry uses traditional (i.e., iron brands and ear tags) and modern (i.e., microchips) identification (ID) systems without having performance results of reference. Previously iron-branded ( = 45; 1 yr) and microchipped ( = 59; 7 yr) camels showed problems of healing (8.6% of brands) and reading (only 42.9% of brands and 69.5% of microchips were readable), which made their use inadvisable. With the aim of proposing suitable ID systems for different farming conditions, an on-field study was performed using a total of 528 dromedaries at 4 different locations (Egypt, = 83; Spain, = 304; Saudi Arabia, = 90; and Tunisia, = 51). The ID devices tested were visual (button ear tags, 28.5 mm diameter, = 178; double flag ear tags, 50 by 15 mm, = 83; both made of polyurethane) and electronic (ear tags, = 90, and rumen boluses, = 555). Electronic ear tags were polyurethane-loop type (75 by 9 mm) with a container in which a 22-mm transponder of full-duplex technology was lodged. Electronic boluses of 7 types, varying in dimensions (50 to 76 mm length, 11 to 21 mm width, and 12.7 to 82.1 g weight) and specific gravity (SG; 1.49 to 3.86) and each of them containing a 31-mm transponder of half-duplex technology, were all administered to the dromedaries at the beginning of the study. When a low-SG bolus was lost, a high-SG bolus was readministered. Readability rates of each ID system were evaluated during 1 to 3 yr, according to device and location, and yearly values were estimated for comparison. On a yearly basis, visual ear tag readability was not fully satisfactory; it was lower for rectangular ear tags (66.3%) than for button ear tags (80.9%). Yearly readability of electronic ear tags was 93.7%. Bolus readability dramatically varied according to their SG; the SG < 2.0 boluses were fully lost after 8 mo. In contrast, the SG > 3.0 boluses were efficiently retained (99.6 to 100%) at all locations. In conclusion, according to the expected long lifespan of camels, low ID performances were observed for iron brands, injectable microchips, and ear tags (visual and electronic), making their use inadvisable as unique ID systems in camels. The high readability of dense electronic boluses recommended their use as a permanent ID device of reference in camels. PMID- 27695806 TI - Assessing cow-calf welfare. Part 2: Risk factors for beef cow health and behavior and stockperson handling. AB - Epidemiological studies can be used to identify risk factors for livestock welfare concerns but have not been conducted in the cow-calf sector for this purpose. The objectives of this study were to investigate the relationships of 1) herd-level management, facilities, and producer perspectives with cattle health and behavior and stockperson handling and 2) stockperson handling on cattle behavior at the individual cow level. Cow ( = 3,065) health and behavior and stockperson handling during a routine procedure (e.g., pregnancy checks) were observed on 30 California ranches. Management and producer perspectives were evaluated using an interview, and handling facility features were recorded at the chute. After predictors were screened for univariable associations, multivariable models were built for cattle health (i.e., thin body condition, lameness, abrasions, hairless patches, swelling, blind eyes, and dirtiness) and behavior (i.e., balking, vocalizing, stumbling and falling in the chute and while exiting the restraint, and running out of the restraint) and stockperson handling (i.e., electric prod use, moving aid use, tail twisting, and mis-catching cattle). When producers empathized more toward an animal's pain experience, there was a lower risk of swelling (odds ratio [OR] = 0.7) but a higher risk of lameness (OR = 1.3), which may indicate a lack of awareness of the latter. Training stockpersons using the Beef Quality Assurance program had a protective effect on cow cleanliness and mis-catching in the restraint (OR = 0.2 and OR = 0.5, respectively). Hydraulic chutes increased the risk of vocalizations (OR = 2.7), possibly because these systems can apply greater pressure to the sides of the animal than manual restraints. When a moving aid was used to move an individual cow, it increased the risk of her balking, but when hands, in particular, were used, the risk of balking decreased across the herd (OR = 34.1 and OR = 0.3, respectively). Likewise, individual cows were at a greater risk of balking, vocalizing, stumbling and falling in the chute, and stumbling and running at exit when they were touched with an electric prod (OR = 11.0, OR = 3.3, OR = 1.9, OR = 2.3, OR = 1.8, and OR = 1.7, respectively). Although the implications of using moving aids are unclear, reducing the use of electric prods could improve cattle handling. In conclusion, cattle handling was influenced by a number of facility and stockperson factors: personnel training, facility design, and electric prod use are key areas for future improvements. PMID- 27695807 TI - Effects of limonene on ruminal concentrations, fermentation, and lysine degradation in cattle. AB - Previous in vitro data showed that was inhibited by limonene. We further evaluated effects of limonene on growth of in vitro as well as on ruminal concentrations of in vivo. With in vitro cultivation in anaerobic brain-heart infusion broth, limonene decreased growth of . Thymol also reduced growth of , but it was less effective than limonene. Tylosin effectively reduced growth of in vitro. Although the response over fermentation times and concentrations of antimicrobials differed somewhat between tylosin and limonene, the 2 antimicrobial agents yielded similar inhibitory effects on growth of at concentrations ranging from 6 to 24 mg/L. The effects of limonene on ruminal concentration in vivo were tested in 7 ruminally cannulated heifers (225 kg initial BW) used in a 7 * 4 Youden square design. Treatments included: 1) control, 2) limonene at 10 mg/kg diet DM, 3) limonene at 20 mg/kg diet DM, 4) limonene at 40 mg/kg diet DM, 5) limonene at 80 mg/kg diet DM, 6) CRINA-L (a blend of essential oil components) at 180 mg/kg diet DM, and 7) tylosin at 12 mg/kg diet DM. Each period included 11 d with 10 d washouts between periods. Samples of ruminal contents were collected before treatment initiation and after 4, 7, and 10 d of treatment for measuring by the most probable number method using selective culture medium. Limonene linearly decreased ( = 0.03) ruminal concentration, with the lowest concentration achieved with 40 mg of limonene/kg dietary DM. Limonene tended ( <= 0.07) to linearly reduce ruminal molar proportions of propionate and valerate while tending to linearly increase ( <= 0.10) those of butyrate and 2-methyl butyrate. Limonene did not affect ruminal NH concentrations or degradation rates of lysine. Neither CRINA-L ( = 0.52) nor tylosin ( = 0.19) affected ruminal concentrations. CRINA-L significantly decreased ruminal concentrations of NH and molar proportions of 3-methyl butyrate, whereas tylosin significantly decreased molar proportions of propionate while increasing those of butyrate and tending to increase those of acetate. Limonene supplementation reduced ruminal concentrations of suggesting that it may have the potential to reduce the prevalence of liver abscesses, although further research is needed to assess the effect of limonene in feedlot cattle. PMID- 27695808 TI - Kinetics of phosphorus absorption in ligated small intestinal segments of broilers. AB - Two experiments were conducted using 22-d-old Arbor Acres male broilers to study the kinetics of inorganic P absorption and the effect of P treatment on Type IIb sodium-phosphate cotransporter (NaP-IIb) mRNA and protein levels in ligated segments from different intestinal regions. In Exp. 1, the P absorption in different small intestinal segments at different postperfusion times (0, 2.5, 5, 10, 20, or 40 min) were compared. In Exp. 2, different small intestinal loops were perfused with solutions containing 0, 1.5, 3, 6, 12, 24, or 48 mmol P/L as KHPO, and P concentrations in perfusates were determined at 20 min after perfusion. The mRNA levels of NaP-IIb in different small intestinal loops and protein expression levels in the duodenums from the control group and the 6 or 48 mmol P/L group were analyzed. The results from Exp. 1 showed that P absorption increased in an asymptotic response to postperfusion time within 40 min in all the intestinal segments and P absorption was greater ( < 0.04) in the duodenum than in the other 2 segments at 20 min after perfusion, indicating that the duodenum is the main site of P absorption in the small intestine of chicks. In Exp. 2, the kinetic curves showed that P absorption in the duodenum was a saturated carrier mediated process and in the jejunum or ileum occurred with a nonsaturated diffusion process. In addition, the b mRNA levels were greater ( < 0.0001) in the duodenum than in the other 2 segments in the 3 groups (0, 6, or 48 mmol P/L), further indicating that P absorption in the duodenum occurred mainly by a saturated carrier mediated process. However, no significant differences ( = 0.20) in the NaP-IIb protein levels of the duodenum were observed among the 0, 6, and 48 mmol P/L groups. In conclusion, this study suggests by our criteria in ligated intestinal loops that the duodenum is the main site of P absorption and that P absorption may be a saturated carrier mediated process in the duodenum but a nonsaturated diffusion process in the jejunum or ileum of broilers.

PMID- 27695810 TI - Effects of dietary copper, zinc, and ractopamine hydrochloride on finishing pig growth performance, carcass characteristics, and antimicrobial susceptibility of enteric bacteria. AB - A total of 480 pigs (PIC 327 * 1050; initially 48.7 +/- 2.3 kg) were used to determine the interactive effects of supplemental Cu, Zn, and ractopamine HCl (RAC) on finishing pig growth performance, carcass characteristics, and antimicrobial susceptibility of enteric bacteria. Treatments were arranged in a 2 * 2 * 2 factorial with the main effects of added Cu (CuSO; 0 vs. 125 mg/kg Cu), Zn (ZnO; 0 vs. 150 mg/kg Zn), and RAC (0 vs. 10 mg/kg during the last 28 d prior to marketing). All diets contained 11 mg/kg Cu and 73 mg/kg Zn from the trace mineral premix. Pens of pigs were balanced and blocked on initial BW and then randomly allotted to 1 of the 4 mineral treatment diets. At 28 d prior to marketing, pens within each block and mineral treatment were randomly assigned to receive either 0 or 10 mg/kg RAC in addition to the mineral treatment. Adding either Cu or Zn alone did not improve ADG or ADFI yet resulted in numerical improvements in overall G:F and caloric efficiencies, but improvements were not additive (Cu * Zn, = 0.057, = 0.068, and = 0.064 for G:F and caloric efficiency on a ME and NE basis, respectively). Ractopamine improved ( < 0.001) overall ADG, G:F, and caloric efficiency, thereby increasing final BW by 3% with no change in ADFI. Ractopamine also increased ( < 0.001) HCW, percentage carcass yield, G:F, loin depth, and percent fat-free lean and decreased ( = 0.014) backfat. Adding Zn or Cu alone to diets containing RAC numerically improved percent yield and HCW G:F, but this effect was absent when the Cu or Zn was added to the control diet or when Cu and Zn were fed in combination in RAC diets (Cu * Zn * RAC, = 0.011 and = 0.018 for yield and HCW G:F, respectively). Fecal samples were collected on d 0 and at the conclusion of the finishing period (d 90) for bacterial isolation and antimicrobial susceptibility determinations according to Clinical and Laboratory Standards Institute minimal inhibitory concentrations breakpoints. spp. and isolates displayed varying levels of resistance to certain antibiotics prior to initiation of treatments on d 0. Resistance to most antibiotics decreased ( < 0.05) over time or was stable for those that had a low baseline percentage of resistance. Neither Zn nor RAC adversely affected antimicrobial resistance. However, extended feeding of 125 mg/kg Cu throughout the finishing period seems to decrease enterococcal susceptability to tetracycline, tylosin, and quinupristin/dalfopristin. PMID- 27695811 TI - Technical note: A special apparatus for facilitating the in situ nylon bag measurement of the ruminal degradation of feedstuffs in cattle. AB - A new apparatus, named Bang-Bang (BB), which can facilitate the in situ nylon bag measurement of ruminal degradation in beef cattle, is described. The BB is an apparatus specially designed as a replacement of the traditional steel chain or flexible plastic tubes for binding the bags used in the in situ nylon bag (ISNB) method. The BB apparatus consists of cylindrical pedestals, sealing clips, nylon string, and nylon bags. A series of in situ rumen incubations using 3 ruminally cannulated beef steers were conducted to compare the BB with the ISNB method by measuring rumen DM degradation kinetics of 12 different feedstuffs commonly offered to beef cattle in China. Greater ( < 0.01) DM disappearance and less ( < 0.01) relative SD (%) were observed with the BB than with the ISNB method. In addition, effective degradability of DM was highly correlated between the 2 methods (ISNB = (1.01 +/- 0.04 * BB) - 4.03 +/- 2.12; = 0.99, < 0.001, = 12). These results indicate that the BB apparatus can be effectively used to determine the rumen degradation properties of feedstuffs with advantages over the traditional ISNB technique. PMID- 27695812 TI - Differences in body condition of gilts that are maintained from mating to the end of gestation affect mammary development. AB - The goal of this project was to determine if different body conditions in late gestation that are due to varying body conditions at mating affect mammary development and mammary gene expression of gilts. Gilts that were fed ad libitum in the growing period were selected based on their backfat depths to form 3 groups at mating, namely, low backfat (LBF; 12-15 mm; = 14), medium backfat (MBF; 17-19 mm; = 15), and high backfat (HBF; 22-26 mm; = 16). During gestation, LBF, MBF, and HBF gilts were fed approximately 1.25, 1.43, and 1.63 times maintenance requirements to maintain their differences in body condition. Feed intake was increased by 1 kg in the last 10 d of gestation. Backfat depths of gilts were ultrasonically measured at mating and on d 30, 50, 70, 100, and 109 of gestation. Blood samples were obtained at mating and on d 109 of gestation to measure concentrations of IGF-1, glucose, insulin, estradiol, urea, free fatty acids, leptin, and adiponectin. Gilts were slaughtered on d 110 of gestation to collect mammary glands for compositional analyses. Mammary extraparenchymal tissue weight was lesser in LBF and MBF gilts than in HBF gilts (1,259.3, 1,402.7, and 1,951.5 +/- 70.4 g, respectively; < 0.01). The weight of parenchymal tissue was not affected by treatment ( > 0.10), but its composition was altered. Concentrations of DNA and RNA decreased as backfat depth increased ( < 0.05), whereas percent fat and DM increased ( < 0.05). Circulating concentrations of leptin tended to be lower at mating ( < 0.10) and were lower on d 109 of gestation ( < 0.05) in LBF gilts than in HBF gilts. On d 109 of gestation, concentrations of insulin ( < 0.01) and IGF-1 ( < 0.05) were lower in LBF and MBF gilts than in HBF gilts, whereas those of urea were greater ( < 0.05). The mRNA abundance in parenchymal tissue for all genes studied was not affected by treatments ( > 0.10) with the exception of , which had a greater expression level in LBF gilts than in MFB or HBF gilts ( < 0.05). Percent of Ki-67-positive cells, used to assess mammary cell proliferation rate, was greater in HBF gilts than in LBF gilts ( < 0.05). When differences in body conditions of gilts that were present at mating were maintained throughout gestation, it had an impact on mammary development. Extraparenchymal tissue mass was affected and, more importantly, composition of parenchymal tissue was altered, indicating a beneficial effect of gilts being in the thinner treatment groups at mating. PMID- 27695813 TI - Dynamics of nitrogen retention in gestating gilts at two feeding levels. AB - Whole-body protein deposition (Pd) is a main determinant of AA requirements of gestating gilts; however, data on the dynamics of Pd is limited. The main objective of this study was to measure whole-body Pd (pregnancy-associated and maternal) during gestation in gilts at 2 feeding levels. Changes in BW and backfat (BF) throughout gestation and subsequent lactation performance were also evaluated. We hypothesized that the effect of feed intake on maternal Pd decreases toward the end of gestation due to increased fetal nutrient demands. Fifty-one pregnant Yorkshire gilts (initial BW and BF at d 28 +/- 0.5 of gestation were 168.6 +/- 2.2 kg and 16.9 +/- 0.8 mm, respectively) were used. Gilts were assigned to 1 of 2 feeding levels (high feeding level and low feeding level; 2.54 and 1.87 kg/d, respectively) of the same diet (3.30 Mcal ME/kg, 17.8% CP, 0.82% standard ileal digestible Lys) from d 33 to 112 +/- 0.5 of gestation. Nitrogen balance observations (based on total urine collection with urinary catheters and determination of fecal N digestibility using an indigestible marker) were made at 5 distinct time periods, each 4 d in length, starting at d 38, 52, 66, 87, and 108 +/- 0.5 of gestation. Pregnancy-associated Pd (fetus, mammary gland, uterus, and placenta and fluids) was calculated for each gilt and N balance period using the gestating sow model, based on actual litter size (including stillborns) and mean piglet birth weight. Maternal Pd was calculated as the difference between whole-body Pd and pregnancy-associated Pd. Across all N balance periods, whole-body and maternal Pd were consistently 40.1 +/- 5.2 g/d greater ( < 0.001) for the high feeding level compared with the low feeding level. At both feeding levels, whole-body Pd increased (linear and quadratic, < 0.020) with day of gestation and maternal Pd decreased (cubic, < 0.010) with day of gestation. During lactation, maternal voluntary feed intake and litter performance were not affected by gestation feeding level. Gilts on the high feeding level lost more BW and BF during lactation ( <= 0.030). In summary, the effect of feeding level on whole-body and maternal Pd was constant throughout gestation. However, the gradual decline in maternal Pd with day of gestation is in contrast to that reported by the and has important implications for the factorial estimation of AA requirements of gestating gilts toward the end of gestation. PMID- 27695814 TI - Production, Management, and Environment Symposium: Environmental footprint of livestock production - Greenhouse gas emissions and climate change. PMID- 27695815 TI - Analytical methods for quantifying greenhouse gas flux in animal production systems. AB - Given increased interest by all stakeholders to better understand the contribution of animal agriculture to climate change, it is important that appropriate methodologies be used when measuring greenhouse gas (GHG) emissions from animal agriculture. Similarly, a fundamental understanding of the differences between methods is necessary to appropriately compare data collected using different approaches and design meaningful experiments. Sources of carbon dioxide, methane, and nitrous oxide emissions in animal production systems includes the animals, feed storage areas, manure deposition and storage areas, and feed and forage production fields. These 3 gases make up the primary GHG emissions from animal feeding operations. Each of the different GHG may be more or less prominent from each emitting source. Similarly, the species dictates the importance of methane emissions from the animals themselves. Measures of GHG flux from animals are often made using respiration chambers, head boxes, tracer gas techniques, or in vitro gas production techniques. In some cases, a combination of techniques are used (i.e., head boxes in combination with tracer gas). The prominent methods for measuring GHG emissions from housing include the use of tracer gas techniques or direct or indirect ventilation measures coupled with concentration measures of gases of interest. Methods for collecting and measuring GHG emissions from manure storage and/or production lots include the use of downwind measures, often using photoacoustic or open path Fourier transform infrared spectroscopy, combined with modeling techniques or the use of static chambers or flux hood methods. Similar methods can be deployed for determining GHG emissions from fields. Each method identified has its own benefits and challenges to use for the stated application. Considerations for use include intended goal, equipment investment and maintenance, frequency and duration of sampling needed to achieve desired representativeness of emissions over time, accuracy and precision of the method, and environmental influences on the method. In the absence of a perfect method for all situations, full knowledge of the advantages and disadvantages of each method is extremely important during the development of the experimental design and interpretation of results. The selection of the suitable technique depends on the animal production system, resource availability, and objective for measurements. PMID- 27695816 TI - Dexamethasone treatment differentially alters viral shedding and the antibody and acute phase protein response after multivalent respiratory vaccination in beef steers. AB - Our objective was to examine immunosuppression induced by dexamethasone (DEX) administration in cattle on immunological responses to a multivalent respiratory vaccine containing replicating and nonreplicating agents. Steers ( = 32; 209 +/- 8 kg) seronegative to infectious bovine rhinotracheitis virus (IBRV), bovine viral diarrhea virus (BVDV), bovine respiratory syncytial virus (BRSV), and parainfluenza-3 virus (PI3V) were stratified by BW and randomly assigned to 1 of 3 treatments: 1) acute immunosuppression (ACU; 0.5 mg/kg BW DEX intravenously at 1000 h only on d 0), 2) chronic immunosuppression (CHR; 0.5 mg/kg BW DEX intravenously at 1000 h on d -3 to 0), or 3) a control (CON; no DEX). On d -4, steers were fitted with intravenous catheters in the jugular vein and placed into individual stanchions. At 1200 h on d 0, steers were administered a respiratory vaccine containing modified-live virus (MLV) isolates of IBRV, BVDV, BRSV, and PI3V and a (MH) toxoid. On d 4, cattle were transported (177 km) and housed in an isolated outdoor pen. Serum was harvested on d 0, 7, 14, 21, 28, 35, 42, and 56 to determine IBRV-, BVDV-, BRSV-, and PI3V-specific antibody titers and MH whole cell and leukotoxin antibody concentrations. Sera from d -2, 0, 1, 3, 7, and 14 were used to quantify haptoglobin (Hp) concentration and ceruloplasmin (Cp) activity. Nasal swab specimens were collected on d 0, 3, and 14 to determine the presence of IBRV, BVDV, BRSV, and PI3V via PCR analysis. There was a treatment * day interaction ( < 0.01) such that CHR steers had a greater ( <= 0.07) BVDV antibody titer on d 14, 21, and 28. Moreover, IBRV-specific antibodies increased beginning on d 14 for CHR and on d 28 for ACU and remained greater through d 56 compared with CON ( <= 0.03). Conversely, serum MH whole cell antibody concentration was least ( <= 0.06) for CHR from d 7 to 28 and greatest for CON ( <= 0.04) on d 56. Treatment altered Hp such that CON exhibited a greater ( < 0.01) Hp concentration than CHR but was not different from ACU ( = 0.16). On d 3, Cp was greatest for CON, intermediate for ACU, and least for CHR (treatment * day; <= 0.01). The prevalence of IBRV and BVDV in nasal swabs on d 14 was 67 and 56%, respectively, for CHR; 10 and 10%, respectively, for CON; and 9 and 0%, respectively, for ACU ( <= 0.006). Results suggest that CHR allowed increased replication of MLV vaccine agents. Conversely, DEX-induced immunosuppression blunted the acute phase protein and antibody response against the nonreplicating MH toxoid. PMID- 27695817 TI - Impacts of supplemental arginine on the reproductive performance of fall lambing ewes. AB - In sheep, embryonic and fetal death during pregnancy can account for 25% to 50% of the total number of corpora lutea (and thus potential embryos). The objective of this study was to determine the effects of injectable and oral Arg supplementation provided for 14 d postbreeding on the reproductive performance of naturally stimulated fall lambing ewes. Rambouillet ewes ( = 210) were exposed to rams equipped with marking harnesses to induce cyclicity in April 2012. Upon estrus detection (d 0) ewes were randomly assigned, in a completely random design, to 1 of 6 treatments for a 14-d treatment period: injectable saline (CON; = 25), injectable Ala (IVALA; = 20), injectable Arg (IVARG; = 23), oral rumen protected Arg (RPARG; = 20), oral fish meal (FM; = 24), or oral soybean meal (SBM; = 23). Daily treatments, except CON, IVALA, and SBM, were formulated to provide supplemental Arg at 30 mg.kg BW.d and were provided at 0800 h daily. Ewes receiving injectable treatments were provided 454 g corn/d postinjection, whereas ewes receiving oral supplements were provided a ground ration of their respective treatments with corn individually at 0800 h daily. Plasma and serum samples were collected on d 0, 2, 4, 6, 8, 10, 12, and 14 from 12 ewes per treatment to evaluate plasma progesterone and serum AA concentrations. At lambing, birth weight, birth type, and sex were recorded. Weaning weights were recorded when the average age of lambs was 85 d. No differences ( >= 0.39) were detected for pregnancy, prolificacy, and lambing rates or lamb birth weights among treatments. However, litter weaning weight tended to be greater ( = 0.06) and weaning rates were greater ( = 0.05) in Arg-injected ewes (1.09, 0.95, 1.29, 0.72, 1.00, and 0.86, respectively). Plasma progesterone and serum Arg concentrations showed a treatment and day effect ( < 0.001), but no treatment * day interaction ( >= 0.99) was observed. In contrast to previous research, supplemental Arg during the first 14 d of pregnancy did not improve pregnancy or lambing rates; however, IVARG did positively impact weaning rates.

PMID- 27695821 TI - Stroke, Bleeding, and Mortality Risks in Elderly Medicare Beneficiaries Treated With Dabigatran or Rivaroxaban for Nonvalvular Atrial Fibrillation. AB - Importance: Dabigatran and rivaroxaban are non-vitamin K oral anticoagulants approved for stroke prevention in patients with nonvalvular atrial fibrillation (AF). There are no randomized head-to-head comparisons of these drugs for stroke, bleeding, or mortality outcomes. Objective: To compare risks of thromboembolic stroke, intracranial hemorrhage (ICH), major extracranial bleeding including major gastrointestinal bleeding, and mortality in patients with nonvalvular AF who initiated dabigatran or rivaroxaban treatment for stroke prevention. Design, Setting, and Participants: Retrospective new-user cohort study of 118 891 patients with nonvalvular AF who were 65 years or older, enrolled in fee-for service Medicare, and who initiated treatment with dabigatran or rivaroxaban from November 4, 2011, through June 30, 2014. Differences in baseline characteristics were adjusted using stabilized inverse probability of treatment weights based on propensity scores. The data analysis was performed from May 7, 2015, through June 30, 2016. Exposures: Dabigatran, 150 mg, twice daily; rivaroxaban, 20 mg, once daily. Main Outcomes and Measures: Adjusted hazard ratios (HRs) for the primary outcomes of thromboembolic stroke, ICH, major extracranial bleeding including major gastrointestinal bleeding, and mortality, with dabigatran as reference. Adjusted incidence rate differences (AIRDs) were also estimated. Results: A total of 52 240 dabigatran-treated and 66 651 rivaroxaban-treated patients (47% female) contributed 15 524 and 20 199 person-years of on-treatment follow-up, respectively, during which 2537 primary outcome events occurred. Rivaroxaban use was associated with a statistically nonsignificant reduction in thromboembolic stroke (HR, 0.81; 95% CI, 0.65-1.01; P = .07; AIRD = 1.8 fewer cases/1000 person years), statistically significant increases in ICH (HR, 1.65; 95% CI, 1.20-2.26; P = .002; AIRD = 2.3 excess cases/1000 person-years) and major extracranial bleeding (HR, 1.48; 95% CI, 1.32-1.67; P < .001; AIRD = 13.0 excess cases/1000 person-years), including major gastrointestinal bleeding (HR, 1.40; 95% CI, 1.23 1.59; P < .001; AIRD = 9.4 excess cases/1000 person-years), and with a statistically nonsignificant increase in mortality (HR, 1.15; 95% CI, 1.00-1.32; P = .051; AIRD = 3.1 excess cases/1000 person-years). In patients 75 years or older or with CHADS2 score greater than 2, rivaroxaban use was associated with significantly increased mortality compared with dabigatran use. The excess rate of ICH with rivaroxaban use exceeded its reduced rate of thromboembolic stroke. Conclusions and Relevance: Treatment with rivaroxaban 20 mg once daily was associated with statistically significant increases in ICH and major extracranial bleeding, including major gastrointestinal bleeding, compared with dabigatran 150 mg twice daily. PMID- 27695822 TI - Alternative Strategies to Inpatient Hospitalization for Acute Medical Conditions: A Systematic Review. AB - Importance: Determining innovative approaches that better align health needs to the appropriate setting of care remains a key priority for the transformation of US health care; however, to our knowledge, no comprehensive assessment exists of alternative management strategies to hospital admission for acute medical conditions. Objective: To examine the effectiveness, safety, and cost of managing acute medical conditions in settings outside of a hospital inpatient unit. Evidence Review: MEDLINE, Scopus, CINAHL, and the Cochrane Database of Systematic Reviews (January 1995 to February 2016) were searched for English-language systematic reviews that evaluated alternative management strategies to hospital admission. Two investigators extracted data independently on trial design, eligibility criteria, clinical outcomes, patient experience, and health care costs. The quality of each review was assessed using the revised AMSTAR tool (R AMSTAR) and the strength of evidence from primary studies was graded according to the Oxford Centre for Evidence-Based Medicine. Findings: Twenty-five systematic reviews (representing 123 primary studies) met inclusion criteria. For outpatient management strategies, several acute medical conditions had no significant difference in mortality, disease-specific outcomes, or patient satisfaction compared with inpatient admission. For quick diagnostic units, the evidence was more limited but did demonstrate low mortality rates and high patient satisfaction. For hospital-at-home, a variety of acute medical conditions had mortality rates, disease-specific outcomes, and patient and caregiver satisfaction that were either improved or no different compared with inpatient admission. For observation units, several acute medical conditions were found to have no difference in mortality, a decreased length of stay, and improved patient satisfaction compared to inpatient admission; results for some conditions were more limited. Across all alternative management strategies, cost data were heterogeneous but showed near-universal savings when assessed. Conclusions and Relevance: For low-risk patients with a range of acute medical conditions, evidence suggests that alternative management strategies to inpatient care can achieve comparable clinical outcomes and patient satisfaction at lower costs. Further study and application of such opportunities for health system redesign is warranted. PMID- 27695823 TI - Association of Stimulant Medication Use With Bone Mass in Children and Adolescents With Attention-Deficit/Hyperactivity Disorder. AB - Importance: Murine studies reveal that sympathetic nervous system activation leads to decreased bone mass. Stimulant medications used to treat attention deficit/hyperactivity disorder (ADHD) increase sympathetic tone and may affect bone remodeling. Because bone mass accrual is completed by young adulthood, assessing stimulant effects on bone density in growing children is of critical importance. Objective: To investigate associations between stimulant use and bone mass in children and adolescents. Design, Setting, and Participants: This cross sectional analysis used data collected from January 1, 2005, to December 31, 2010, from the National Health and Nutrition Examination Survey (NHANES) database. NHANES is a series of cross-sectional, nationally representative health and nutrition surveys of the US population. All children, adolescents, and young adults aged 8 to 20 years with dual-energy x-ray absorptiometry (DXA), anthropometric, demographic, and prescription medication use data were eligible for participation. Of the 6489 respondents included in the multivariable linear regression analysis, 159 were stimulant users and 6330 were nonusers. Data were analyzed from October 8, 2015, to December 31, 2016. Exposures: Stimulant use, determined by questionnaires administered via interview. Main Outcomes and Measures: The association between stimulant use and total femur, femoral neck, and lumbar spine bone mineral content (BMC) and bone mineral density (BMD) was assessed using DXA. Results: Study participants included 6489 NHANES participants with a mean (SD) age of 13.6 (3.6) years. Stimulant use was associated with lower bone mass after adjustment for covariates. Mean lumbar spine BMC was significantly lower in stimulant users vs nonusers (12.76 g; 95% CI, 12.28-13.27 g vs 13.38 g; 95% CI, 13.26-13.51 g; P = .02), as was mean lumbar spine BMD (0.90 g/cm2; 95% CI, 0.87-0.94 g/cm2 vs 0.94 g/cm2; 95% CI, 0.94-0.94 g/cm2; P = .03) and mean femoral neck BMC (4.34 g; 95% CI, 4.13-4.57 g vs 4.59 g; 95% CI, 4.56 4.62 g; P = .03). Mean BMD of the femoral neck (0.88 g/cm2; 95% CI, 0.84-0.91 g/cm2 vs 0.91 g/cm2; 95% CI, 0.90-0.91 g/cm2; P = .08) and total femur (0.94 g/cm2; 95% CI, 0.90-0.99 g/cm2 vs 0.99 g/cm2; 95% CI, 0.98-0.99 g/cm2; P = .05) were also lower in stimulant users vs nonusers. Participants treated with stimulants for 3 months or longer had significantly lower lumbar spine BMD (0.89 g/cm2; 95% CI, 0.85-0.93 g/cm2 vs 0.94 g/cm2; 95% CI, 0.94-0.94 g/cm2; P = .02) and BMC (12.71 g; 95% CI, 12.14-13.32 g vs 13.38 g; 95% CI, 13.25-13.51 g; P = .03) and femoral neck BMD (0.87 g/cm2; 95% CI, 0.74-0.83 g/cm2 vs 0.91 g/cm2; 95% CI, 0.83-0.84 g/cm2; P = .048) than nonusers. Conclusions and Relevance: Children and adolescents reporting stimulant use had lower DXA measurements of the lumbar spine and femur compared with nonusers. These findings support the need for future prospective studies to examine the effects of stimulant use on bone mass in children.

AB - Importance: Adjunctive hydrocortisone therapy is suggested by the Surviving Sepsis Campaign in refractory septic shock only. The efficacy of hydrocortisone in patients with severe sepsis without shock remains controversial. Objective: To determine whether hydrocortisone therapy in patients with severe sepsis prevents the development of septic shock. Design, Setting, and Participants: Double-blind, randomized clinical trial conducted from January 13, 2009, to August 27, 2013, with a follow-up of 180 days until February 23, 2014. The trial was performed in 34 intermediate or intensive care units of university and community hospitals in Germany, and it included 380 adult patients with severe sepsis who were not in septic shock. Interventions: Patients were randomly allocated 1:1 either to receive a continuous infusion of 200 mg of hydrocortisone for 5 days followed by dose tapering until day 11 (n = 190) or to receive placebo (n = 190). Main Outcomes and Measures: The primary outcome was development of septic shock within 14 days. Secondary outcomes were time until septic shock, mortality in the intensive care unit or hospital, survival up to 180 days, and assessment of secondary infections, weaning failure, muscle weakness, and hyperglycemia (blood glucose level >150 mg/dL [to convert to millimoles per liter, multiply by 0.0555]). Results: The intention-to-treat population consisted of 353 patients (64.9% male; mean [SD] age, 65.0 [14.4] years). Septic shock occurred in 36 of 170 patients (21.2%) in the hydrocortisone group and 39 of 170 patients (22.9%) in the placebo group (difference, -1.8%; 95% CI, -10.7% to 7.2%; P = .70). No significant differences were observed between the hydrocortisone and placebo groups for time until septic shock; mortality in the intensive care unit or in the hospital; or mortality at 28 days (15 of 171 patients [8.8%] vs 14 of 170 patients [8.2%], respectively; difference, 0.5%; 95% CI, -5.6% to 6.7%; P = .86), 90 days (34 of 171 patients [19.9%] vs 28 of 168 patients [16.7%]; difference, 3.2%; 95% CI, -5.1% to 11.4%; P = .44), and 180 days (45 of 168 patients [26.8%] vs 37 of 167 patients [22.2%], respectively; difference, 4.6%; 95% CI, -4.6% to 13.7%; P = .32). In the hydrocortisone vs placebo groups, 21.5% vs 16.9% had secondary infections, 8.6% vs 8.5% had weaning failure, 30.7% vs 23.8% had muscle weakness, and 90.9% vs 81.5% had hyperglycemia. Conclusions and Relevance: Among adults with severe sepsis not in septic shock, use of hydrocortisone compared with placebo did not reduce the risk of septic shock within 14 days. These findings do not support the use of hydrocortisone in these patients. Trial Registration: clinicaltrials.gov Identifier: NCT00670254.

AB - Importance: Measles is a highly communicable viral infection with serious complications. There have been continued outbreaks of measles in countries in which measles is considered to be eliminated, such as the United States and the Netherlands, and measles remains endemic in some countries. Health care professionals play an important role in diagnosing and managing acute cases of measles, preventing spread during outbreaks, and vaccination uptake. Objective: To provide an overview of measles and vaccination for health care professionals. Evidence Review: MEDLINE and PubMed were searched from January 1, 1980, to April 30, 2016, in addition to the data repositories of the Centers for Disease Control and Prevention and World Health Organization. Findings: Seven systematic reviews, 15 reviews, 15 observational studies, 1 qualitative study, 5 epidemiologic reports, and 2 books were included, in addition to World Health Organization and Centers for Disease Control and Prevention data, position papers, and statements. Transmission of measles is dependent on person-to-person spread through respiratory droplets or direct contact. Diagnosis is based on recognizing the clinical picture and can be confirmed with results of laboratory testing, such as serologic tests or polymerase chain reaction. Measles infection leads to immune suppression for weeks to months. Complications of measles are of high frequency and severity. There is no specific antiviral treatment for measles; treatment with vitamin A is recommended for younger children to decrease mortality from measles. Vaccination against measles is effective, cost-effective, and safe. There is no link between the measles vaccination and autism. Measles can be eliminated from a population; this outcome requires coverage with 2 doses of vaccine at rates of 93% to 95% of the population. Countries with high rates of measles vaccination experience outbreaks by virtue of imported cases causing transmission through susceptible groups of individuals who are not immune to the measles virus. Endemic transmission can be reestablished if rates of vaccination fall below the elimination threshold. Conclusions and Relevance: Measles remains of high clinical importance. Health care professionals should be able to diagnose and manage an acute case and assist in prevention of the spread of measles during an outbreak. Health care professionals also play an important role in uptake of measles vaccination through establishing trusting relationships with parents, offering vaccination at indicated times, and engaging parents in discussion on facts and concerns about vaccination.

PMID- 27695851 TI - Effects of ParentCorps in Prekindergarten on Child Mental Health and Academic Performance: Follow-up of a Randomized Clinical Trial Through 8 Years of Age. AB - Importance: Low-income minority children living in urban neighborhoods are at high risk for mental health problems and underachievement. ParentCorps, a family centered, school-based intervention in prekindergarten, improves parenting and school readiness (ie, self-regulation and preacademic skills) in 2 randomized clinical trials. The longer-term effect on child mental health and academic performance is not known. Objective: To examine whether ParentCorps delivered as an enhancement to prekindergarten programs in high-poverty urban schools leads to fewer mental health problems and increased academic performance in the early elementary school years. Design, Setting, and Participants: This is a 3-year follow-up study of a cluster randomized clinical trial of ParentCorps in public schools with prekindergarten programs in New York City. Ten elementary schools serving a primarily low-income, black student population were randomized in 2005, and 4 consecutive cohorts of prekindergarten students were enrolled from September 12, 2005, through December 31, 2008. We report follow-up for the 3 cohorts enrolled after the initial year of implementation. Data analysis was performed from September 1, 2014, to December 31, 2015. Interventions: ParentCorps included professional development for prekindergarten and kindergarten teachers and a program for parents and prekindergarten students (13 two-hour group sessions delivered after school by teachers and mental health professionals). Main Outcomes and Measures: Annual teacher ratings of mental health problems and academic performance and standardized tests of academic achievement in kindergarten and second grade by testers masked to the intervention or control group randomization. Results: A total of 1050 children (4 years old; 518 boys [49.3%] and 532 girls [50.7%]) in 99 prekindergarten classrooms participated in the trial (88.1% of the prekindergarten population), with 792 students enrolled from 2006 to 2008. Most families in the follow-up study (421 [69.6%]) were low income; 680 (85.9%) identified as non-Latino black, 78 (9.8%) as Latino, and 34 (4.3%) as other. Relative to their peers in prekindergarten programs, children in ParentCorps-enhanced prekindergarten programs had lower levels of mental health problems (Cohen d = 0.44; 95% CI, 0.08 0.81) and higher teacher-rated academic performance (Cohen d = 0.21; 95% CI, 0.02 0.39) in second grade. Conclusions and Relevance: Intervention in prekindergarten led to better mental health and academic performance 3 years later. Family centered early intervention has the potential to prevent problems and reduce disparities for low-income minority children. Trial Registration: clinicaltrials.gov Identifier: NCT01670227.

AB - Importance: Recent studies have reported an increase in the number of fetuses and neonates with microcephaly whose mothers were infected with the Zika virus (ZIKV) during pregnancy. To our knowledge, most reports to date have focused on select aspects of the maternal or fetal infection and fetal effects. Objective: To describe the prenatal evolution and perinatal outcomes of 11 neonates who had developmental abnormalities and neurological damage associated with ZIKV infection in Brazil. Design, Setting, and Participants: We observed 11 infants with congenital ZIKV infection from gestation to 6 months in the state of Paraiba, Brazil. Ten of 11 women included in this study presented with symptoms of ZIKV infection during the first half of pregnancy, and all 11 had laboratory evidence of the infection in several tissues by serology or polymerase chain reaction. Brain damage was confirmed through intrauterine ultrasonography and was complemented by magnetic resonance imaging. Histopathological analysis was performed on the placenta and brain tissue from infants who died. The ZIKV genome was investigated in several tissues and sequenced for further phylogenetic analysis. Main Outcomes and Measures: Description of the major lesions caused by ZIKV congenital infection. Results: Of the 11 infants, 7 (63.6%) were female, and the median (SD) maternal age at delivery was 25 (6) years. Three of 11 neonates died, giving a perinatal mortality rate of 27.3%. The median (SD) cephalic perimeter at birth was 31 (3) cm, a value lower than the limit to consider a microcephaly case. In all patients, neurological impairments were identified, including microcephaly, a reduction in cerebral volume, ventriculomegaly, cerebellar hypoplasia, lissencephaly with hydrocephalus, and fetal akinesia deformation sequence (ie, arthrogryposis). Results of limited testing for other causes of microcephaly, such as genetic disorders and viral and bacterial infections, were negative, and the ZIKV genome was found in both maternal and neonatal tissues (eg, amniotic fluid, cord blood, placenta, and brain). Phylogenetic analyses showed an intrahost virus variation with some polymorphisms in envelope genes associated with different tissues. Conclusions and Relevance: Combined findings from clinical, laboratory, imaging, and pathological examinations provided a more complete picture of the severe damage and developmental abnormalities caused by ZIKV infection than has been previously reported. The term congenital Zika syndrome is preferable to refer to these cases, as microcephaly is just one of the clinical signs of this congenital malformation disorder.

PMID- 27695865 TI - Efficacy and safety of 5% minoxidil topical foam in male pattern hair loss treatment and patient satisfaction. AB - INTRODUCTION: Male pattern hair loss is widespread around the world. Its prevalence indicates the importance of finding the best treatment modalities. This study evaluates the efficacy and safety of minoxidil 5% topical foam in male pattern hair loss treatment and patient satisfaction. METHODS: This study was a before-and-after trial on 17 male patients with male pattern hair loss. Subjects were instructed to apply one capful (1 ml) of minoxidil 5% topical foam on the scalp daily for 6 months. Efficacy was assessed through hair counts, subject assessment, and global photographic review. RESULTS: Seventeen male volunteers were recruited, and three volunteers were withdrawn; 14 participated in the trial for 16 weeks, and 12 continued up to 24 weeks. The average hair count with a camera at week 16 (181.87 +/- 52.42) and week 24 (194.58 +/- 62.82) and with an eye count at week 16 (62.57 +/- 15.28) and week 24 (69.91 +/- 15.61) increased significantly compared to the baseline after intervention. CONCLUSIONS: This study confirmed that minoxidil 5% topical foam is a safe and effective treatment for MPHL. The effect of it is evident after 24 weeks of use. PMID- 27695866 TI - Evaluation of hygiene habits: cross-sectional study. AB - Introduction: It is well known that adequate hygiene is important for health. Even though this topic has drawn the attention of the media, little or no scientific investigation has been done. Methods: We performed a comparative questionnaire-based cross-sectional study in three groups: patients attending a dermatology outpatient clinic, patients attending an internal medicine consultation, and community members. Results: We analyzed a total of 446 questionnaires (249 from dermatology patients, 98 from internal medicine patients, and 99 from the community group). The three groups did not differ statistically in sex and age (p=0.070). The patients from the dermatology department had a higher education level. The number of weekly baths did not differ among the three groups (p=0.417). Hair hygiene did not differ between the three groups. The dermatology and internal medicine groups washed their hands more frequently than the community group (p=0.028). Conclusions: Comparing our results to the limited data available, we find that the population surveyed has better hygiene habits than those previously reported. We believe that hygiene habits should be discussed during office visits.

The patient was successfully treated with systemic immunosuppressive therapy and primary closure. PMID- 27695867 TI - Hepatitis D virus infection in Slovenian patients with chronic hepatitis B virus infection: a national prevalence study and literature review. AB - INTRODUCTION: Of the 350 million individuals chronically infected with hepatitis B virus (HBV) worldwide, approximately 15 to 20 million have been exposed to hepatitis D virus (HDV). This study determined for the first time the HDV prevalence in Slovenian patients with chronic HBV infection. In addition, a literature search was performed to identify all HDV prevalence studies from European countries. METHODS: A total of 1,305 HBsAg-positive serum samples, obtained from the same number of patients, were randomly selected from 2,337 patients referred to the Slovenian national reference laboratory for viral hepatitis between 1998 and 2015. All samples were retrospectively tested for the presence of total anti-HDV antibodies. Anti-HDV-positive patients were additionally tested for the presence of anti-HDV IgM antibodies, HDV antigen, and HDV RNA. RESULTS: Total anti-HDV antibodies were detected in three of the 1,305 patients tested (0.23%; 95% CI: 0.08-0.67%), of whom one patient had recovered from the past HDV infection and two patients had an ongoing chronic HDV infection. The literature search identified 36 peer-reviewed HDV prevalence studies published between 1983 and 2016 and originating from 21 European countries. CONCLUSIONS: The observed prevalence of HDV infection in Slovenia was among the lowest reported in Europe and worldwide. Due to the observed low prevalence of HDV infection, routine diagnostic testing for HDV should not be considered in differential diagnosis of exacerbation of liver disease in Slovenian patients with chronic HBV infection. PMID- 27695869 TI - Very recent HIV infection accompanied by Pneumocystis jirovecii pneumonia and Mycobacterium avium complex immune reconstitution inflammatory syndrome: a case report. AB - A small proportion of HIV-infected patients rapidly progress to AIDS; indeed, some individuals have been known to progress to AIDS within a year after primary infection. Pneumonia caused by Pneumocystis jirovecii (PCP) is the most frequent AIDS-defining illness. However, PCP can also rarely occur during primary HIV infection as a result of the severe immunosuppression that may accompany the early stage of HIV infection. Immune reconstitution inflammatory syndrome (IRIS) comprises two distinct syndromes: paradoxical IRIS and unmasking IRIS. Infections with Mycobacterium avium complex during antiretroviral therapy are almost always localized and related to IRIS. We describe an unusual case of PCP and Mycobacterium avium complex-IRIS that occurred less than 3 months after primary HIV infection.

PMID- 27695872 TI - Understanding cardiomyocyte proliferation: an insight into cell cycle activity. AB - Cardiomyocyte proliferation and regeneration are key to the functional recovery of myocardial tissue from injury. In the recent years, studies on cardiomyocyte proliferation overturned the traditional belief that adult cardiomyocytes permanently withdraw from the cell cycle activity. Hence, targeting cardiomyocyte proliferation is one of the potential therapeutic strategies for myocardial regeneration and repair. To achieve this, a deep understanding of the fundamental mechanisms involved in cardiomyocyte cell cycle as well as differences between neonatal and adult cardiomyocytes' cell cycle activity is required. This review focuses on the recent progress in understanding of cardiomyocyte cell cycle activity at different life stages viz., gestation, birth, and adulthood. The temporal expression/activities of major cell cycle activators (cyclins and CDKs), inhibitors (p21, p27, p57, p16, and p18), and cell-cycle-associated proteins (Rb, p107, and p130) in cardiomyocytes during gestation and postnatal life are described in this review. The influence of different transcription factors and microRNAs on the expression of cell cycle proteins is demonstrated. This review also deals major pathways (PI3K/AKT, Wnt/beta-catenin, and Hippo-YAP) associated with cardiomyocyte cell cycle progression. Furthermore, the postnatal alterations in structure and cellular events responsible for the loss of cell cycle activity are also illustrated. PMID- 27695875 TI - ? PMID- 27695874 TI - Pleiotropic regulations of neutrophil receptors response to sepsis. AB - INTRODUCTION: Sepsis is a complex clinical condition that causes a high mortality rate worldwide. Numerous studies on the pathophysiology of sepsis have revealed an imbalance in the inflammatory network, thus leading to tissue damage, organ failure, and ultimately death. The impairment of neu-trophil migration is associated with the outcome of sepsis. METHODS: Literature review was performed on the roles of neutrophil recruitment and neutrophil receptors as pleiotropic regulators during sepsis. Additionally, we systematically classify neutrophil receptors with regard to the neutrophil response during sepsis and discuss the clinical implications of these receptors for the treatment of sepsis. RESULTS: Increasing evidence suggests that there is significant dysfunction in neutrophil recruitment during sepsis, characterized by the failure to migrate to the site of infection. Neutrophil receptors, as pleiotropic regulators, play important roles in the neutrophil response during sepsis. CONCLUSIONS: Neutrophil receptors play key roles in chemotactic neutrophil migration and may prove to be suitable targets in future pharmacological therapies for sepsis.

AB - The mammalian olfactory bulb is a forebrain structure just one synapse downstream from the olfactory sensory neurons and performs the complex computations of sensory inputs. The formation of this sensory circuit is shaped through activity dependent and cell-intrinsic mechanisms. Recent studies have revealed that cell type specific connectivity and the organization of synapses in dendritic compartments are determined through cell-intrinsic programs already preset in progenitor cells. These progenitor programs give rise to subpopulations within a neuron type that have distinct synaptic organizations. The intrinsically determined formation of distinct synaptic organizations requires factors from contacting cells that match the cell-intrinsic programs. While certain genes control wiring within the newly generated neurons, other regulatory genes provide intercellular signals and are only expressed in neurons that will form contacts with the newly generated cells. Here, the olfactory system has provided a useful model circuit to reveal the factors regulating assembly of the highly structured connectivity in mammals.

AB - KEY MESSAGE: Integration of previous Mendelian genetic analyses and recent molecular genomics approaches, such as linkage mapping and QTL cloning, dramatically strengthened our current understanding of genetic control of rice flowering time. Flowering time is one of the most important agronomic traits for seed production in rice (Oryza sativa L.). It is controlled mainly by genes associated with photoperiod sensitivity, particularly in short-day plants such as rice. Since the early twentieth century, rice breeders and researchers have been interested in elucidating the genetic basis of flowering time because its modification is important for regional adaptation and yield optimization. Although flowering time is a complex trait controlled by many quantitative trait loci (QTLs), classical genetic studies have shown that many associated genes are inherited in accordance with Mendelian laws. Decoding the rice genome sequence opened a new era in understanding the genetic control of flowering time on the basis of genome-wide mapping and gene cloning. Heading date 1 (Hd1) was the first flowering time QTL to be isolated using natural variation in rice. Recent accumulation of information on rice genome has facilitated the cloning of other QTLs, including those with minor effects on flowering time. This information has allowed us to rediscover some of the flowering genes that were identified by classical Mendelian genetics. The genes characterized so far, including Hd1, have been assigned to specific photoperiod pathways. In this review, we provide an overview of the studies that led to an in-depth understanding of the genetic control of flowering time in rice, and of the current state of improving and fine tuning this trait for rice breeding.

AB - Closed tendon ruptures of the thumb that require secondary reconstruction can affect the extensor pollicis longus (EPL), extensor pollicis brevis (EPB) and flexor pollicis longus (FPL) tendons. Treatment of rupture of the EPB tendon consists of refixation to the bone and temporary transfixation of the joint. In the case of preexisting or posttraumatic arthrosis, definitive arthrodesis of the thumb is the best procedure. Closed ruptures of the EPL and FPL tendons at the wrist joint cannot be treated by direct tendon suture. Rupture of the EPL tendon occurs after distal radius fractures either due to protruding screws or following conservative treatment especially in undisplaced fractures. Transfer of the extensor indicis tendon to the distal EPL stump is a good option and free interposition of the palmaris longus tendon is a possible alternative. The tension should be adjusted to slight overcorrection, which can be checked intraoperatively by performing the tenodesis test. Closed FPL ruptures at the wrist typically occur 3-6 months after osteosynthesis of distal radius fractures with palmar plates and are mostly characterized by crepitation and pain lasting for several weeks. They can be prevented by premature plate removal, synovectomy and carpal tunnel release. For treatment of a ruptured FPL tendon in adult patients the options for tendon reconstruction should be weighed up against the less complicated tenodesis or arthrodesis of the thumb interphalangeal joint. PMID- 27695882 TI - Angina, back pain and septic shock. PMID- 27695880 TI - [Current aspects of therapy of rhizoarthrosis]. AB - In patients with carpometacarpal osteoarthritis of the thumb, treatment strategies should be based on functional impairment and pain. Although X-ray imaging is an integral component of the diagnostics, it is of subordinate importance for the therapy algorithm. Conservative therapy is always the first step in the chain of treatment. The efficacy of non-operative treatment, including intermittent immobilization using splinting and the application of technical assist devices in the daily routine has been proven to achieve pain relief. The intra-articular injection of hyaluronic acid or glucocorticoids is still under debate as some good experiences in routine clinical applications are contrasted by the lack of effectiveness in randomized studies. The indications for operative treatment are fulfilled by persisting pain after exhausting all the options for conservative therapy. In this case isolated trapeziectomy is the method of choice. Suspension (interpositioning) arthroplasty is not associated with improved clinical results. More recent procedures which aim to avoid proximalization by tendon interposition, have not yet shown better clinical outcome compared to trapeziectomy alone. PMID- 27695879 TI - Cyclin D1, cancer progression, and opportunities in cancer treatment. AB - Mammalian cells encode three D cyclins (D1, D2, and D3) that coordinately function as allosteric regulators of cyclin-dependent kinase 4 (CDK4) and CDK6 to regulate cell cycle transition from G1 to S phase. Cyclin expression, accumulation, and degradation, as well as assembly and activation of CDK4/CDK6 are governed by growth factor stimulation. Cyclin D1 is more frequently dysregulated than cyclin D2 or D3 in human cancers, and as such, it has been more extensively characterized. Overexpression of cyclin D1 results in dysregulated CDK activity, rapid cell growth under conditions of restricted mitogenic signaling, bypass of key cellular checkpoints, and ultimately, neoplastic growth. This review discusses cyclin D1 transcriptional, translational, and post translational regulations and its biological function with a particular focus on the mechanisms that result in its dysregulation in human cancers.

AB - Neglect is a supramodal, clinically relevant disorder, which occurs in the different sensory modalities as well as in the mental representation. The different manifestations of neglect show interindividual and intraindividual variation. Different spatial and attention-related interventions lead to varying degrees of improvement in neglect symptoms but are often not stable in time or transferable to activities of daily living. Representational deficits or body related aspects to modify personal neglect are rarely a priority in current therapies. Because of the multisensory and motor deficits from our point of view the future of neglect rehabilitation lies in a combined therapy of visual exploration, motor imagery with intensive motor therapy of motor sensory deficits and probably best reinforced by continued neck muscle vibration or allocation of attention to the neglected side.

AB - Sepsis is a major growing global burden and a major challenge to intensive care clinicians, researchers, guideline committee members and policy makers, because of its high and increasing incidence and great pathophysiological, molecular, genetic and clinical complexity. In spite of recent progress, short-term mortality remains high and there is growing evidence of long-term morbidity and increased long-term mortality in survivors of sepsis both in developed and developing countries. Further improvement in the care of patients with sepsis will impact upon global health. In this narrative review, invited experts describe the expected challenges and progress to be made in the near future. We focus on diagnosis, resuscitation (fluids, vasopressors, inotropes, blood transfusion and hemodynamic targets) and infection (antibiotics and infection biomarkers), as these areas are key, if initial management and subsequent outcomes are to be improved in patients with sepsis. PMID- 27695890 TI - Seeds of doubt: Mendel's choice of Hieracium to study inheritance, a case of right plant, wrong trait. AB - KEY MESSAGE: In this review, we explore Gregor Mendel's hybridization experiments with Hieracium , update current knowledge on apomictic reproduction and describe approaches now being used to develop true-breeding hybrid crops. From our perspective, it is easy to conclude that Gregor Mendel's work on pea was insightful, but his peers clearly did not regard it as being either very convincing or of much importance. One apparent criticism was that his findings only applied to pea. We know from a letter he wrote to Carl von Nageli, a leading botanist, that he believed he needed to "verify, with other plants, the results obtained with Pisum". For this purpose, Mendel adopted Hieracium subgenus Pilosella, a phenotypically diverse taxon under botanical study at the time. What Mendel could not have known, however, is that the majority of these plants are not sexual plants like pea, but instead are facultatively apomictic. In these forms, the majority of seed arises asexually, and such progeny are, therefore, clones of the maternal parent. Mendel obtained very few hybrids in his Hieracium crosses, yet we calculate that he probably emasculated in excess of 5000 Hieracium florets to even obtain the numbers he did. Despite that effort, he was perplexed by the results, and they ultimately led him to conclude that "the hybrids of Hieracium show a behaviour exactly opposite to those of Pisum". Apomixis is now a topic of intense research interest, and in an ironic twist of history, Hieracium subgenus Pilosella has been developed as a molecular model to study this trait. In this paper, we explore further Mendel's hybridization experiments with Hieracium, update current knowledge on apomictic reproduction and describe approaches now being used to develop true-breeding hybrid crops.

PMID- 27695894 TI - A recovery program to improve quality of life, sense of coherence and psychological health in ICU survivors: a multicenter randomized controlled trial, the RAPIT study. AB - PURPOSE: The aim of this randomized controlled trial (RCT) was to test the effectiveness of a post-ICU recovery program compared to standard care during the first year after ICU discharge. METHODS: A pragmatic, non-blinded, multicenter, parallel-group RCT was conducted between December 2012 and December 2015, at ten intensive care units (ICUs) in Denmark. We randomly assigned 386 adult patients (>=18 years) after receiving mechanical ventilation (>=48 h) to standard care (SC) plus a nurse-led intensive care recovery program or standard care alone after ICU discharge (190 intervention, 196 SC). Primary outcome was health related quality of life (HRQOL) at 12 months. Secondary outcomes were sense of coherence (SOC), anxiety, depression, and post-traumatic stress disorder (PTSD) assessed at 3 and 12 months after ICU discharge including utilization of healthcare services at 12 months. RESULTS: At 12 months, we found no differences in HRQOL between groups (mean difference in the Physical Component Summary score, 1.41 [95 % CI, -1.53 to 4.35; p = 0.35] (n = 235); and in the Mental Component Summary score, 1.92 [95 % CI, -1.06 to 4.90; p = 0.11] (n = 235). No differences were found on self-reported SOC (p = 0.63), anxiety (p = 0.68), depression (p = 0.67), PTSD (p = 0.27), or the utilization of healthcare services including rehabilitation. We found a difference on anxiety, when a cut-off point >=11 was applied, in per protocol analysis of complete cases at 3 months favoring the intervention (8.8 % vs. 16.2 %, p = 0.04).

The present study aimed to reveal the mechanisms of IR cleavage. METHODS: Using the in vitro model, we investigated the molecular mechanisms of IR cleavage, which is accelerated by high-glucose treatment. We also analysed the relationship between IR cleavage and cellular insulin resistance, and the correlation between plasma sIR levels and insulin sensitivity, which was assessed by the euglycaemic-hyperinsulinaemic clamp technique. RESULTS: Here, we determined that calpain 2, which is secreted into the extracellular space associated with exosomes, directly cleaved the ectodomain of the IRbeta subunit (IRbeta), which in turn promoted intramembrane cleavage of IRbeta by gamma-secretase. IR cleavage impaired insulin signalling and the inhibition of IR cleavage (by knockdown of calpain 2 and gamma-secretase), restored IR substrate-1 and Akt, independent of IR. Furthermore, the glucose lowering drug, metformin, prevented IR cleavage accompanied by inhibition of calpain 2 release in exosomes, and re-established insulin signalling. In patients with type 2 diabetes, plasma sIR levels inversely correlated with insulin sensitivity. CONCLUSIONS/INTERPRETATION: Sequential cleavage of IR by calpain 2 and gamma-secretase may contribute to insulin signalling in cells and its inhibition may be partly responsible for the glucose-lowering effects of metformin. Thus, IR cleavage may offer a new mechanism for the aetiology of insulin resistance. PMID- 27695900 TI - An oxidative stress paradox: time for a conceptual change? AB - Oxidative stress has long been considered a key driving factor of many obesity related health problems. However, recent work by Merry, Tran et al (Diabetologia DOI 10.1007/s00125-016-4084-3 ) challenges this idea with an interesting study using a hepatocyte-specific Gpx1-knockout (HGKO) mouse. GPX1 is an important detoxification enzyme that converts H2O2 to water. The authors found that high fat diet-fed HGKO mice were more insulin sensitive than wildtype controls, despite elevated hepatic levels of H2O2 and evidence of increased systemic oxidative stress. When challenged with a non-alcoholic steatohepatitis (NASH) inducing diet, HGKO mice were also protected, displaying reduced levels of inflammation and fibrosis with similar levels of steatosis compared with controls. These findings call into question the role of reactive oxygen species in NASH pathogenesis and highlight a potential paradox whereby increased H2O2 may be beneficial in some contexts.

AB - OBJECTIVES: To describe trends in measles vaccine coverage rates and their association with socioeconomic characteristics among children from age 12 to 23 months in Vietnam from the year 2000 to 2014. METHODS: Data were drawn from the Vietnam Multiple Indicator Cluster Surveys in years 2000, 2006, 2011, and 2014. Concentration indices were used to determine the magnitude of socioeconomic inequalities in measles vaccine coverage. Associations between measles vaccine coverage and relevant social factors were assessed using logistic regression. RESULTS: Socioeconomic inequalities in measles vaccine coverage rates decreased during 2000-2014. Children belonging to ethnic minority groups, having mothers with lower education, and belonging to the poorest group were less likely to receive measles vaccine; although, their vaccine coverage rates did increase with time. Measles vaccine coverage declined among children of mothers with more education and belonging to the wealthiest socioeconomic group. CONCLUSIONS: Understanding the social factors influencing adherence to recommend childhood vaccination protocols is essential. Attempts to regain and retain herd immunity must be guided by an understanding of these social factors if they are to succeed. PMID- 27695902 TI - Caterpillar hairs as an anti-parasitoid defence. AB - Caterpillar hairs are thought to act as a physical barrier against natural enemies, including parasitoids. However, very few studies have experimentally demonstrated how hairs protect caterpillars from parasitoid oviposition. To clarify the importance of caterpillar hairs as an anti-parasitoid defence, we observed the generalist endoparasitoid Meteorus pulchricornis (Hymenoptera: Braconidae) attacking both smooth and hairy caterpillars under laboratory conditions. A female Meteorus pulchricornis uses its ovipositor to inject venom and lay a single egg inside host larvae. We placed a smooth Spodoptera litura (Lepidoptera: Noctuidae) caterpillar or a hairy Lymantria dispar japonica (Lepidoptera: Erebidae) caterpillar in front of parasitoid females. We observed that 100 % and 84 % of the parasitoids could successfully stab their ovipositors into the smooth larvae of S. litura and first instars of the hairy caterpillar L. dispar japonica, respectively. However, only 24 % of parasitoids could successfully stab their ovipositors into second-instar L. dispar japonica. A higher rate of successful stabs (94 %) by parasitoids was obtained by cutting the hairs of second instar L. dispar japonica much shorter than the parasitoid ovipositor. The results demonstrate that the long, thick hairs of second and later instars of L. dispar japonica function as a physical barrier against parasitoid oviposition.

AB - Nesting behavior is considered to be an important element of social living in animals. The spider mites belonging to the genus Stigmaeopsis spend their lives within nests produced from silk threads. Several of these species show cooperative sociality, while the others are subsocial. In order to identify the origins of this social behavior, comparisons of nest sizes, nesting behaviors (making nests continuously or separately), and their associated traits (fecal deposition patterns) were made for eight cogeneric Stigmaeopsis species showing various levels of social development. All of these species inhabit bamboo plants (Poaceae). We initially addressed the proximate factor of nest size variation. The variation in nest size of the eight species corresponded well with the variation in dorsal seta sc1 length, suggesting that nest size variation among species may have a genetic basis. The time spent within a nest (nest duration) increased with nest size on the respective host plants. Nest arrangement patterns varied among species showing different sized nests: Large nest builders continuously extended their nests, while middle and small nest-building species built new separate nests, which resulted in different social interaction times among species, and is thought to be closely related to social development. Fecal deposition behaviors also varied among Stigmaeopsis species, suggesting diversity in anti-predatory adaptations. Finally, we discuss how the variation in sociality observed within this genus is likely the result of nest size variation that initially evolved as anti-predator strategies. PMID- 27695904 TI - Articular cartilage paste graft for severe osteochondral lesions of the knee: a 10- to 23-year follow-up study. AB - PURPOSE: The purpose of this study is to evaluate the clinical outcomes of the articular cartilage paste graft procedure at a minimum of 10 years from surgery. It is hypothesized that articular cartilage paste grafting can provide patients with a durable repair of severe full-thickness osteochondral injuries, measured by persistence of procedure-induced benefit and subjective outcome scores at 10 or more years. METHODS: Seventy-four patients undergoing paste grafting at a mean age of 45.3 +/- 10.8 years (range 13-69 years) were followed up at a mean of 16.8 +/- 2.4 years (range 10.6-23.2 years) post-operatively using validated subjective outcome measures; Kaplan-Meier survival analysis was performed to estimate expected population benefit time. RESULTS: Kaplan-Meier estimated median benefit time of 19.1 years (mean: 16.6 +/- 0.9 years) for all patients undergoing paste grafting. Thirty-one (41.9 %) patients had progressed to arthroplasty at a mean of 9.8 +/- 5.6 years (range 0.4-20.6 years). Ninety percent of patients reported that the procedure provided good to excellent pain relief. Median IKDC subjective score increased significantly at most recent follow-up (70.1) compared to preoperative (55.7, p = 0.013). Median WOMAC scores decreased significantly from 26 to 14 (p = 0.001). Median Tegner score increase from 4 to 6 was not found to be significant (ns). VAS pain averaged 23/100 at most recent follow-up. CONCLUSIONS: Patients who underwent the paste grafting reported improved pain, function, and activity levels for an expected mean of 16.6 years, and for those who ultimately progressed to knee replacement, surgical treatment including the paste graft was able to delay arthroplasty until a mean age of 60.2 years, an age at which the procedure is commonly performed. Full-thickness articular cartilage loss can be successfully treated, reducing pain, and improving function, using this single-step, inexpensive arthroscopic procedure. LEVEL OF EVIDENCE: IV. PMID- 27695905 TI - The efficacy of post-operative devices following knee arthroscopic surgery: a systematic review. AB - PURPOSE: There is a wide array of device modalities available for post-operative treatment following arthroscopic knee surgery; however, it remains unclear which types and duration of modality are the most effective. This systematic review aimed to investigate the efficacy of device modalities used following arthroscopic knee surgery. METHODS: A systematic search of the literature was performed on: PubMed; Scopus; MEDLINE; EMBASE; PEDro; SportDiscus; and CINAHL databases (1995-2015) for clinical trials using device modalities following arthroscopic knee surgery: cryotherapy, continuous passive motion (CPM), neuromuscular electrical stimulation (NMES), surface electromyographic (sEMG) biofeedback and shockwave therapy (ESWT). Only level 1 and 2 studies were included and the methodological quality of studies was evaluated using Physiotherapy Evidence Database (PEDro) scores. Outcome measures included: muscle strength, range of motion, swelling, blood loss, pain relief, narcotic use, knee function evaluation and scores, patient satisfaction and length of hospital stay. RESULTS: Twenty-five studies were included in this systematic review, nineteen of which found a significant difference in outcomes. For alleviating pain and decreasing narcotic consumption following arthroscopic knee surgery, cryocompression devices are more effective than traditional icing alone, though not more than compression alone. CPM does not affect post-operative outcomes. sEMG biofeedback and NMES improve quadriceps strength and overall knee functional outcomes following knee surgery. There is limited evidence regarding the effects of ESWT. CONCLUSION: Cryotherapy, NMES and sEMG are recommended for inclusion into rehabilitation protocols following arthroscopic knee surgery to assist with pain relief, recovery of muscle strength and knee function, which are all essential to accelerate recovery. CPM is not warranted in post-operative protocols following arthroscopic knee surgery because of its limited effectiveness in returning knee range of motion, and additional studies are required to investigate the effects of ESWT. LEVEL OF EVIDENCE: II. PMID- 27695906 TI - Is there a distinct pattern to the acetabular labrum and articular cartilage damage in the non-dysplastic hip with instability? AB - PURPOSE: The purpose of this study was to determine whether or not there is a distinct pattern of injury to the acetabular labrum and/or cartilage in the hip with instability without bony dysplasia. METHODS: Surgical records and intra operative images of consecutive patients who underwent primary hip arthroscopy for femoroacetabular impingement (FAI) and/or hip instability by the senior author from April 2007 to December 2014 were retrospectively reviewed. Pathological changes were documented and charted on a novel diagram of the acetabulum, and classified into eight patterns corresponding to the lesion's location and size. In patients who had acetabular chondroplasty treatment, the width of the cartilage lesion was recorded. RESULTS: A total of 953 hips in 886 patients were included, and patients who met our inclusion/exclusion criterion were grouped into an Instability-Only group (45 hips), an Instability-Dysplasia group (12 hips), as well as Pincer-FAI, Cam-FAI, and Combined-FAI groups consisting of 100, 54, and 269 hips, respectively. In the Instability-Only group, 42.2 % of the chondral and labral lesions demonstrated a "Straight-Anterior" pattern, which proportion was statistically significantly different compared with Pincer-FAI (p < 0.000), Cam-FAI (p = 0.0002), and Combined-FAI (p < 0.000) groups. In Instability-Only patients, only 15.6 % of the lesions had an "Anterior to Lateral" pattern, a significantly lower proportion (p < 0.000) compared with the FAI groups. Also 11.1 % of the lesions demonstrated a "Lateral" pattern, which is a significantly greater proportion compared with Pincer-FAI (p < 0.000) and Combined-FAI (p < 0.000) groups. The mean width of the cartilage lesions for the Instability-Only group was 2.9 mm, which was significantly shallower than for the other FAI groups (p < 0.000). CONCLUSION: A significant predilection of "Straight-Anterior" or "Lateral" location of labral and/or cartilage damage was observed in the hip with instability, while there was shallow width of articular cartilage damage in these patients. These results suggest that there is a distinctive labral and cartilage damage pattern for hips with instability without inherent bony dysplasia. LEVEL OF EVIDENCE: Diagnostic study, Level IV. PMID- 27695907 TI - Cochliobolus lunatus down-regulates proteome at late stage of colonization and transiently alters StNPR1 expression in Solanum tuberosum L. AB - Cochliobolus lunatus abundantly produces four-celled conidia at high temperatures (>30 degrees C) and under suitable conditions; the fungus colonizes potato (Solanum tuberosum L.) cultivars by adopting different invasion strategies at the microscopic level. Long-lasting defence during infection requires an upsurge in proteome changes particularly pathogenesis-related proteins chiefly under the control of nonexpresser of pathogenesis-related proteins. In order to gain molecular insights, we profiled the changes in proteome and potato nonexpresser of pathogenesis-related proteins (StNPR1) during the infection process. It is found that C. lunatus significantly (P < 0.05) suppressed the host functional proteome by 96 h after infection (hai), principally, affecting the expression of ribulose bisphosphate carboxylase enzyme, plastidic aldolase enzyme, alcohol dehydrogenase 2 and photosystem II protein prior to the formation of brown-to black leaf spot disease. Strongest host response was observed at 24 hai hallmarked by 307 differentially expressed peptide spots concurring with the active phase of production of penetrating hyphae. Additionally, C. lunatus differentially down-regulated StNPR1 transcript by 8.19 fold by 24 hai. This study is the first to elucidate that C. lunatus transiently down-regulates the expression of StNPR1 at the onset of infection, and as a whole, infection negatively affects the expression of proteome components involved in photosynthesis, carbon fixation and light assimilation. This study contributes towards better understanding of the mechanism underlining the invasion strategies of C. lunatus. PMID- 27695908 TI - Reply to Rahbar K et al.

PMID- 27695911 TI - Molecular analysis of the role of osmolyte transporters opuCA and betL in Listeria monocytogenes after cold and freezing stress. AB - Listeria monocytogenes is a food-borne pathogen of humans and other animals. The striking ability to survive several stresses usually used for food preservation makes L. monocytogenes one of the biggest concerns to the food industry. This ubiquity can be partly explained by the ability of the organism to grow and persist at very low temperatures, a consequence of its ability to accumulate cryoprotective compound called osmolytes. A quantitative RT-PCR assay was used to measure mRNA transcript accumulation for the stress response genes opuCA and betL (encoding carnitine and betaine transporters, respectively) and the housekeeping gene 16S rRNA. Assays were conducted on mid-exponential phase L. monocytogenes cells exposed to conditions reflecting cold and freezing stress, conditions usually used to preserve foods. We showed that expression of the two cold-adapted genes encoded the transporters of the cryoprotectants carnitine and betaine in ATCC 19115 and the food-isolated L. monocytogenes S1 is induced after cold and freezing stress exposure. Furthermore, transcriptional analysis of the genes encoding opuCA and betL revealed that each transporter is induced to different degrees upon cold shock of L. monocytogenes ATCC 19115 and S1. Our results confirm an increase in carnitine uptake at low temperatures more than in betaine after cold-shocked temperature compared to the non-stress control treatment. It was concluded the use of carnitine and betaine as cryoprotectants is essential for rapid induction of the tested stress response under conditions typically encountered during food preservation. PMID- 27695910 TI - A comparative study of the evolution of cellobiose utilization in Escherichia coli and Shigella sonnei. AB - The chb operon of Escherichia coli is involved in the utilization of chitooligosaccharides. While acquisition of two classes of mutations leading to altered regulation of the chb operon is necessary to confer the ability to utilize the glucose disaccharide cellobiose to wild-type strains of E. coli, in the closely related organism Shigella sonnei, Cel+ mutants arise relatively faster, requiring only a single mutational event. In Type I mutants, the insertion of IS600 at -21 leads to ChbR regulator-independent, constitutive expression of the operon. In Type II mutants, the insertion of IS2/600 within the distal binding site of the negative regulator NagC leads to ChbR-dependent cellobiose-inducible expression of the operon. These studies underscore the significance of strain background, specifically the diversity of transposable elements, in the evolution of novel metabolic functions. Constitutive expression of the chb operon also enables utilization of the aromatic beta-glucosides arbutin and salicin, implying that the chb structural genes are inherently promiscuous. PMID- 27695912 TI - Effects of integrated feedback on discrete bimanual movements in choice reaction time. AB - The ability to coordinate the simultaneous movements of our arms is limited by a coalition of constraints. Some of these constraints can be overcome when the task conceptualisation is improved. The present study investigated how the movement preparation of bimanual reaching movements was affected by integrated visual feedback of the responses. Previous research has shown that the preparation of bimanual asymmetric movements takes longer than bimanual symmetric movements. The goal of the present study was to determine whether integrated, Lissajous feedback could eliminate this bimanual asymmetric cost. Fifteen participants made unimanual and bimanual symmetric and asymmetric reaches with separate feedback, where there was a cursor and a target for each hand. Participants also made bimanual symmetric and asymmetric movements with integrated feedback; a single cursor and a single target represented the locations and goals of both arms in this condition. The results showed a bimanual asymmetric cost with separate feedback, and that this cost persisted with integrated feedback. We suggest that integrated feedback improved continuous and discrete bimanual movements in other experiments by facilitating error detection and correction processes. We hypothesise that the bimanual asymmetric cost persisted in the present experiment because the uncertainty associated with choice reaction time prevented the facilitated error processing from improving the preparation of the next trial. PMID- 27695914 TI - Brain natriuretic peptide for prevention of contrast-inducednephropathy: a meta analysis of randomized controlled trials. AB - PURPOSE: Contrast-induced nephropathy (CIN) is a serious complication and associated with poor clinical outcomes. The protective value of brain natriuretic peptide (BNP) administration on CIN is still controversial in patients undergoing percutaneous coronary intervention (PCI) or coronary angiography (CAG). We performed a meta-analysis of randomized controlled trials (RCTs) for BNP in preventing CIN. METHODS: We systematically searched PubMed, Web of Science, Cochrane Library, and ClinicalTrials.gov for RCTs comparing administration of BNP versus non-BNP for preventing CIN. Publication bias was assessed by funnel plots. Relative risk (RR) was calculated for incidence of CIN and major adverse cardiovascular events (MACEs) using the random or fixed effect model according to heterogeneity analysis. RESULTS: There were five RCTs with 1441 patients in this analysis. BNP treatment was associated with lower incidence of CIN (RR = 0.38, 95 % CI 0.27-0.54, p < 0.001) and MACEs (RR = 0.47, 95 % CI 0.24-0.95, p = 0.034) with no significant heterogeneity (I 2 = 0 %, p = 0.701; I 2 = 60 %, p = 0.113, respectively). Similar results were seen in subgroup analysis. Prophylactic BNP significantly decreased the incidence of CIN after cardiac catheterization in the studies of regarding sodium chloride as placebo (I 2 = 0 %, RR = 0.39, 95 % CI 0.27-0.56, p < 0.001) or JADAD score > 3 (I 2 = 0 %, RR = 0.38, 95 % CI 0.21 0.68, p = 0.001). CONCLUSIONS: Preprocedural BNP treatment significantly decreased the incidence of CIN and short-term MACEs in patients undergoing PCI or CAG. PMID- 27695915 TI - Amoxicillin-clavulanic acid and ciprofloxacin-treated SPF mice as gnotobiotic model. AB - The experiment was carried out on 24 SPF BALB/c female mice and lasted for 15 days with a 5-day antibiotic (ATB) treatment and then 10 days without ATB treatment. The aim of our study was to acquire an animal model with reduced and controlled microflora and, at the same time, to ensure that the good health of these animals is maintained. Per oral administration of amoxicillin and clavulanate potassium in Amoksiklav (Sandoz, Slovenia) at a dose of 387.11 mg/kg body weight (0.2 ml of dilution per mouse) and subcutaneous administration of ciprofloxacin in Ciloxan (Alcon, Spain) at a dose of 18.87 mg/kg body weight (0.1 ml of dilution per mouse) were performed every 12 h during first 5 days of experiment. Five-day treatment with ATB led to a reduced survivability of microorganisms in faeces (28.33 +/- 0.43 % on day 2) and caecum content (28.10 +/ 1.56 %), where no cultivable microorganisms in faeces were present. Ten-day convalescence of decontaminated animals under gnotobiotic conditions prevented recovery of species diversity in mice gut microflora. This was reduced to two detectable cultivable species, namely Escherichia coli (GenBank KX086704) and Enterococcus sp. (GenBank KX086705) which were capable to restore its metabolic (CRL 2012) and morphological potential (Baratta et al. Histochem Cell Biol 131:713-726, 2009) within physiological range. Animals obtained under this procedure can be used in further studies. As a result, we created a mouse gnoto model with reduced and controlled microflora without alteration of the overall health status of the respective animals. PMID- 27695913 TI - Footprint area analysis of binary imaged Cupriavidus necator cells to study PHB production at balanced, transient, and limited growth conditions in a cascade process. AB - Statistical distribution of cell and poly[3-(R)-hydroxybutyrate] (PHB) granule size and number of granules per cell are investigated for PHB production in a five-stage cascade (5CSTR). Electron microscopic pictures of cells from individual cascade stages (R1-R5) were converted to binary pictures to visualize footprint areas for polyhydroxyalkanoate (PHA) and non-PHA biomass. Results for each stage were correlated to the corresponding experimentally determined kinetics (specific growth rate MU and specific productivity pi). Log-normal distribution describes PHA granule size dissimilarity, whereas for R1 and R4, gamma distribution best reflects the situation. R1, devoted to balanced biomass synthesis, predominately contains cells with rather small granules, whereas with increasing residence time tau, maximum and average granule sizes by trend increase, approaching an upper limit determined by the cell's geometry. Generally, an increase of intracellular PHA content and ratio of granule to cell area slow down along the cascade. Further, the number of granules per cell decreases with increasing tau. Data for MU and pi obtained by binary picture analysis correlate well with the experimental results. The work describes long term continuous PHA production under balanced, transient, and nutrient-deficient conditions, as well as their reflection on the granules size, granule number, and cell structure on the microscopic level. PMID- 27695916 TI - Taxonomical and functional microbial community dynamics in an Anammox-ASBR system under different Fe (III) supplementation. AB - In the present study, we explored the metabolic versatility of anaerobic ammonium oxidation (anammox) bacteria in a variety of Fe (III) concentrations. Specifically, we investigated the impacts of Fe (III) on anammox growth rates, on nitrogen removal performance, and on microbial community dynamics. The results from our short-term experiments revealed that Fe (III) concentrations (0.04-0.10 mM) significantly promote the specific anammox growth rate from 0.1343 to 0.1709 d-1. In the long-term experiments, the Anammox-anaerobic sequencing batch reactor (ASBR) was operated over 120 days and achieved maximum NH4+-N, NO2--N, and TN efficiencies of 90.98 +/- 0.35, 93.78 +/- 0.29, and 83.66 +/- 0.46 %, respectively. Pearson's correlation coefficients between anammox-(narG + napA), anammox-nrfA, and anammox-FeRB all exceeded r = 0.820 (p < 0.05), confirming an interaction and ecological association among the nitrogen and iron-cycling related microbial communities. Illumina MiSeq sequencing indicated that Chloroflexi (34.39-39.31 %) was the most abundant phylum in an Anammox-ASBR system, followed by Planctomycetes (30.73-35.31 %), Proteobacteria (15.40-18.61 %), and Chlorobi (4.78-6.58 %). Furthermore, we found that higher Fe (III) supplementation (>0.06 mM) could result in the community succession of anammox species, in which Candidatus Brocadia and Candidatus Kuenenia were the dominant anammox bacteria species. Combined analyses indicated that the coupling of anammox, dissimilatory nitrogen reduction to ammonium, and iron reduction accounted for nitrogen loss in the Anammox-ASBR system. Overall, the knowledge gained in this study provides novel insights into the microbial community dynamics and metabolic potential of anammox bacteria under Fe (III) supplementation. PMID- 27695917 TI - Elucidating the origin of HLA-B*73 allelic lineage: Did modern humans benefit by archaic introgression? AB - A previous study reported that some of the human leukocyte antigen (HLA) alleles and haplotypes in present-day humans were acquired by admixture with archaic humans; specifically, an exceptionally diverged HLA-B*73 allele was proposed to be transmitted from Denisovans, although the DNA sequence of HLA-B*73 has not been detected in the Denisovan genome. Here, we argue against the hypothesis that HLA-B*73 introgressed from Denisovans into early modern humans. A phylogenetic analysis revealed that HLA-B*73:01 formed a monophyletic group with a chimpanzee MHC-B allele, strongly suggesting that the HLA-B*73 allelic lineage has been maintained in humans as well as in chimpanzees since the divergence of humans and chimpanzees. The global distribution of HLA-B*73 allele showed that the population frequency of HLA-B*73 in west Asia (0.24 %)-a possible site of admixture with Denisovans-is lower than that in Europe (0.72 %) and in south Asia (0.69 %). Furthermore, HLA-B*73 is not observed in Melanesia even though the Melanesian genome contains the highest proportion of Denisovan ancestry in present-day human populations. Single nucleotide polymorphisms in HLA-A*11-HLA C*12:02 or HLA-A*11-C*15 haplotypes, one of which was assumed to be transmitted together with HLA-B*73 from Denisovans by the study of Abi-Rached and colleagues, were not differentiated from those in other HLA-A-C haplotypes in modern humans. These results do not support the introgression hypothesis. Thus, we conclude that it is highly likely that HLA-B*73 allelic lineage has been maintained in the direct ancestors of modern humans. PMID- 27695918 TI - Assessing adherence to inhaled corticosteroids in asthma patients using an integrated measure based on primary and secondary adherence. AB - PURPOSE: There are very few studies on primary adherence (i.e., first filling of a prescription) to inhaled corticosteroids (ICS) in asthma patients; two have involved children. Moreover, adherence can be overestimated when considering only secondary adherence (i.e., following the medication recommendations for a defined period) and ignoring primary adherence. We aimed thus to evaluate the real-world primary and secondary adherence to ICS and to develop an integrated primary and secondary adherence (IPSA) measure. METHODS: From two clinical databases of pediatric and adult asthma patients, we included 198 children and 206 adults with one ICS prescription recorded in their medical chart between 2010 and 2012 and follow-up data for >=12 months. Adherence was estimated from written prescriptions and prescription claims data. Primary adherence was defined as filling the ICS prescription at a pharmacy within 12 months. Secondary adherence was defined as the proportion of days covered (PDC) in subjects who filled their prescription at least once. The IPSA was based on the PDC with a correction factor for primary adherence. RESULTS: Primary adherence to ICS at 12 months was 89.4 % in children and 69.4 % in adults. Secondary adherence at 12 months in children was 33.9 %, and the IPSA was 30.3 %. These values were 52.8 and 36.6 %, respectively, in adults. CONCLUSIONS: Primary adherence to ICS is low in adults and secondary adherence is poor in children and adults. Using the PDC as a unique measure of adherence led to significant overestimation in adults; IPSA leads to more valid estimates of adherence to ICS.

PMID- 27695919 TI - A machine-learned computational functional genomics-based approach to drug classification. AB - OBJECTIVE: The public accessibility of "big data" about the molecular targets of drugs and the biological functions of genes allows novel data science-based approaches to pharmacology that link drugs directly with their effects on pathophysiologic processes. This provides a phenotypic path to drug discovery and repurposing. This paper compares the performance of a functional genomics-based criterion to the traditional drug target-based classification. METHODS: Knowledge discovery in the DrugBank and Gene Ontology databases allowed the construction of a "drug target versus biological process" matrix as a combination of "drug versus genes" and "genes versus biological processes" matrices. As a canonical example, such matrices were constructed for classical analgesic drugs. These matrices were projected onto a toroid grid of 50 * 82 artificial neurons using a self organizing map (SOM). The distance, respectively, cluster structure of the high dimensional feature space of the matrices was visualized on top of this SOM using a U-matrix. RESULTS: The cluster structure emerging on the U-matrix provided a correct classification of the analgesics into two main classes of opioid and non opioid analgesics. The classification was flawless with both the functional genomics and the traditional target-based criterion. The functional genomics approach inherently included the drugs' modulatory effects on biological processes. The main pharmacological actions known from pharmacological science were captures, e.g., actions on lipid signaling for non-opioid analgesics that comprised many NSAIDs and actions on neuronal signal transmission for opioid analgesics. CONCLUSIONS: Using machine-learned techniques for computational drug classification in a comparative assessment, a functional genomics-based criterion was found to be similarly suitable for drug classification as the traditional target-based criterion. This supports a utility of functional genomics-based approaches to computational system pharmacology for drug discovery and repurposing. PMID- 27695922 TI - Comparing and refining karst disturbance index methods through application in an island karst setting. AB - The interconnected nature of surface and subsurface karst environments allows easy disturbance to their aquifers and specialized ecosystems from anthropogenic impacts. The karst disturbance index is a holistic tool used to measure disturbance to karst environments and has been applied and refined through studies in Florida and Italy, among others. Through these applications, the karst disturbance index has evolved into two commonly used methods of application; yet, the karst disturbance index is still susceptible to evaluation and modification for application in other areas around the world. The geographically isolated and highly vulnerable municipality of Arecibo, Puerto Rico's karst area provides an opportunity to test the usefulness and validity of the karst disturbance index in an island setting and to compare and further refine the application of the original and modified methods. This study found the both methods of karst disturbance index application resulted in high disturbance scores (Original Method 0.54 and Modified Method 0.69, respectively) and uncovered multiple considerations for the improvement of the karst disturbance index. An evaluation of multiple methods together in an island setting also resulted in the need for adding additional indicators, including Mogote Removal and Coastal Karst. Collectively, the results provide a holistic approach to using the karst disturbance index in an island karst setting and suggest a modified method by which scaling and weighting may compensate for the difference between the original and modified method scores and allow interested stakeholders to evaluate disturbance regardless of his or her level of expertise.

AB - RATIONALE: Nicotine and bupropion have been demonstrated to enhance the value of other reinforcers, and this may partially account for nicotine reward and dependence. Evidence suggests that the sexes differ in their sensitivity to the primary and secondary reinforcing effects of nicotine and nicotine-associated stimuli. Whether the sexes also differ in sensitivity to the reward-enhancing effects of nicotine (and bupropion) is yet unclear. OBJECTIVES: The present study evaluated potential sex differences in the enhancement effects of nicotine and bupropion using a reinforcer demand approach. Furthermore, we sought to investigate the role that D1- and D2-type dopamine receptors play in the reward enhancing effects of nicotine and bupropion. METHODS: Demand for sensory reinforcement was assessed in male and female rats responding on a progression of fixed ratio schedules. The effects of nicotine and 10 or 20 mg/kg bupropion on reinforcer demand were assessed within subjects. Subsequently, the effects of SCH 23390 and eticlopride were assessed on the enhancing effects of nicotine and bupropion on progressive ratio responding. RESULTS: Nicotine and bupropion enhanced demand metrics of reinforcement value in both sexes. Females were more sensitive to the enhancement effects of bupropion assessed by reinforcer demand and progressive ratio performance. D2-like dopamine receptor antagonism by eticlopride attenuated the enhancement effects of bupropion, but not of nicotine. CONCLUSIONS: Nicotine and bupropion both enhance reinforcement value in both sexes, though females may be more sensitive to the reward-enhancing effects of bupropion. D2- and possibly D1-type receptors appear to be involved in the reward enhancing effects of bupropion, but not necessarily nicotine.

AB - Hard structures along the southern shore of Lake Michigan restrict natural longshore sediment transport, destabilizing the shoreline, and dissecting the coast into localized shoreline reaches. A geometric design was used to sample (n = 590 nodes) at nine shoreline reaches near the Indiana Dunes National Lakeshore to characterize existing sediment in the offshore and onshore zones. Cluster Analysis grouped shoreline sites into two clusters. Factor Analysis showed that 35 % of the sand fractionation's cumulative variance across all sites was explained by an increased loading on medium sand (0.250 mm) with a corresponding decrease loading on small pebbles (4.750 mm), and an additional 30 % of the cumulative variance was explained by a negative loading on very fine sand (0.075 mm). Individual clusters showed that 43 % of the cumulative variance within cluster one could be explained by increased loadings on fine and medium sand (0.149-0.250 mm) with a corresponding negative loading on small pebbles (4.75 mm). An additional 22 % of the cumulative variance was explained by the positive loading on coarse sand (0.850 mm). Cluster two was explained by a single factor (62 % cumulative variance) highlighting an increased loading on small pebbles and coarse sand, and decreased loadings on medium to very fine sand. Principal component analysis showed that sediment characterization of the swash zone provided the best explanation of between site variance. PMID- 27695924 TI - Features of human autologous hamstring graft elongation after pre-tensioning in anterior cruciate ligament reconstruction. AB - PURPOSE: Precise pre-tensioning protocol of the graft has not been determined in anterior cruciate ligament (ACL) reconstruction. The aims of this study are to measure the human autologous graft elongation, and to reveal what portion of the graft elongated greater after pre-tensioning in ACL reconstruction. METHODS: Twenty-four hamstring tendon grafts which were harvested from patients were included. A continuous load of 150 N was applied to the graft twice for 30 seconds each (150 N-1 minute), and the same loading was repeatedly applied (150 N 2 minute). The amount of elongation of the tendon portion (Length T) and the stitched portion (Length S) were measured after each pre-tensioning. RESULTS: Length S gradually increased by 1.57 +/- 0.67 mm after the 150 N-1 minute pre tensioning and by 2.12 +/- 0.76 mm after the 150 N-2 minute pre-tensioning, respectively. Length T was not significantly elongated after 150 N-1 min (p = 0.66) and 150 N-2 min (p = 0.59). CONCLUSIONS: Graft elongation of the approximately 2 mm was observed, particularly in the stitched portion. It is necessary for a surgeon to focus on careful removal of slack from each stitch during suturing. PMID- 27695925 TI - A Randomised Clinical Trial to Compare Coaxial and Noncoaxial Techniques in Percutaneous Core Needle Biopsy of Renal Parenchyma. AB - PURPOSE: To compare the coaxial and noncoaxial techniques of renal parenchymal core needle biopsy. MATERIALS AND METHODS: This is an institutional review board approved randomised controlled trial comparing 83 patients (male, n = 49) who underwent renal parenchymal core biopsy with coaxial method and 83 patients (male, n = 40) with noncoaxial method. The rate of complications, the number of glomerular profiles, and the procedural time were evaluated in a comparison of the two methods. Correlation between the presence of renal parenchymal disease and the rate of complication was also evaluated. RESULTS: The procedural time was significantly shorter in the coaxial technique (coaxial group, 5 +/- 1 min; noncoaxial group, 14 +/- 2 min; p < 0.001). The rates of complications for the coaxial method was significantly lower than the noncoaxial method (coaxial group, 10.8 %; noncoaxial group, 24.1 %; p = 0.025). There was no significant correlation between gender and the rate of complication. The number of glomerular profiles was significantly higher in patents who underwent renal biopsy with the coaxial method (coaxial group, 18.2 +/- 9.1; noncoaxial group, 8.6 +/- 5.5; p < 0.001). In the whole study population, the rate of complications was significantly higher in patients with a pathologic renal parenchyma compared to those with a normal parenchyma (19/71 vs. 10/95; p = 0.006). CONCLUSIONS: Renal parenchymal biopsy using a coaxial needle is a faster and safer method with a lower rate of complications.

PMID- 27695926 TI - Microstructures of Randall's plaques and their interfaces with calcium oxalate monohydrate kidney stones reflect underlying mineral precipitation mechanisms. AB - Randall's plaques (RP) are preferred sites for the formation of calcium oxalate monohydrate (COM) kidney stones. However, although processes of interstitial calcium phosphate (CaP) plaque formation are not well understood, the potential of plaque microstructures as indicators of CaP precipitation conditions received only limited attention. We investigated RP-associated COM stones for structural details of the calcified tissues and microstructural features of plaque-stone interfaces as indicators of the initial processes of stone formation. Significantly increased CaP supersaturation can be expected for interstitial fluid, if reabsorbed ions from the tubular system continuously diffuse into the collagenous connective tissue. Densely packed, fine-grained CaP particles were found in dense textures of basement membranes while larger, laminated particles were scattered in coarse-meshed interstitial tissue, which we propose to be due to differential spatial confinements and restrictions of ion diffusion. Particle morphologies suggest an initial precipitation as metastable amorphous calcium phosphate (ACP). Morphologies and arrangements of first COM crystals at the RP stone interface ranged from stacked euhedral platelets to skeletal morphologies and even porous, dendritic structures, indicating, in this order, increasing levels of COM supersaturation. Furthermore, these first COM crystals were often coated with CaP. On this basis, we propose that ions from CaP-supersaturated interstitial fluid may diffuse through porous RP into the urine, where a resulting local increase in COM supersaturation could trigger crystal nucleation and, hence, initiate stone formation. Ion-depleted fluid in persistent pores of initial COM layers may get replenished from interstitial fluid, leading to CaP precipitation in porous COM.

AB - We investigated age-related differences in motor behavior under different task contexts of isometric force control. The tasks involved rapid force production and force maintenance, either separately or in combination. For the combined context, we used Fitts-like tasks, in which we scaled either the force level (D manipulation, i.e., manipulation of the amplitude of the force to be produced) or the tolerance range (W manipulation, i.e., manipulation of the target width in which force is allowed to fluctuate). We studied two age groups and analyzed mainly variables that quantify behavioral variability (SD), information processing (signal-to-noise ratio and efficiency functions), and age-related slowing (slowing ratio). For rapid force control, age-related differences were more pronounced when preplanned processes were primarily involved, that is, in the rapid force production and Fitts-D manipulation tasks. Further, older adults were comparable to the younger adults in terms of end-point variability at the cost of being slower and more variable in timing. For force maintenance control, requiring mainly online control, age-related differences were the most visible in the stabilized phase of Fitts-D manipulation, followed by Fitts-W manipulation for SD, and then the force maintenance task. In sum, our findings reveal an age related reorganization of how preplanned and online control processes are combined under different force control contexts. Indeed, both behavioral slowing and the overreliance on online control processes seem to be dependent on the task. In this respect, beyond the study of force control, we show the interest of investigating age effects using functionally different tasks. PMID- 27695931 TI - Modulation of digestive enzyme activities in the avian digestive tract in relation to diet composition and quality. AB - In nature, birds are faced with variable food sources that may differ in composition (protein vs. carbohydrates) and quality (highly digestible material vs. indigestible fiber). Studies in passerine birds and some commercial poultry demonstrate that the gastrointestinal tract can respond to varying diet composition and quality by changing morphology and/or activities of digestive enzymes. However, studies in additional avian species are warranted to understand generalities of these trends. We first fed juvenile mallards (Anas platyrhynchos), chickens (Gallus gallus), and quails (Coturnix coturnix) on either high-carbohydrate or high-protein diets. For the most part, birds fed the high-carbohydrate diet had higher small intestinal and cecal disaccharidase activities (maltase and sucrase). However, only mallards exhibited higher small intestinal aminopeptidase-N (APN) activities when fed the high-protein diet. These results differ from passerine birds, which largely modulate small intestinal proteases, but not disaccharidases. In another trial, we fed Canada geese (Branta canadensis) diets that varied in both their protein and fiber concentrations for approximately 3.5 months. Birds fed the high-fiber diets had significantly longer small intestines and caeca compared to those fed low-fiber diets. Additionally, geese fed the high-fiber diets exhibited lower mass-specific activities of small intestinal sucrase, and higher activities of APN when summed across the small intestine and ceca. Similar to the avian species above, geese fed the high-protein diets did not exhibit flexibility in their small intestinal APN activities. Overall, these experiments demonstrate that responsiveness of the avian digestive tract to diet composition may have phylogenetic or ecological constraints. Studies on other avian taxa are needed to understand these patterns. PMID- 27695933 TI - Evidence-based medicine in plastic surgery. PMID- 27695932 TI - The significance of extramural venous invasion in R1 positive rectal cancer. AB - BACKGROUND AND AIMS: Evidence has shown that a positive resection margin (R1) is a key determinant of subsequent local recurrence and a poor prognostic factor in rectal cancer. The aim of this study was to evaluate the outcomes and prognosticators in patients with R1 resection of rectal cancer. MATERIAL AND METHODS: Retrospective study of all patients operatively managed within our institution between April 2008 and April 2013 for rectal cancer. Baseline demographics and multiple outcome measures recorded. Overall survival (OS), disease-free survival (DFS) and recurrence were the primary outcome measures. RESULTS: Overall, there were 306 primary rectal cancers. Seventy-six percent were grade T3/4 tumours. OS was 30 months. R1 rate was 16 % (48 patients). Thirty-one patients underwent APR and 17 AR. In patients who responded to neoadjuvant chemotherapy (NAC), overall survival was 55 months, with no extramural venous invasion (EMV) seen in this cohort. In non-responders OS was 29 months, with EMV in 48 %. In patients who did not receive NAC, OS was 23 months, with EMV in 74 %. EMV is a strong predictor for poor survival following R1 (p = 0.001). We also found a correlation between number of positive nodes and OS/DFS (p = 0.004). CONCLUSIONS: In this small cohort of patients with R1 positive rectal cancers, response to NAC is the strongest predictor of poor overall and disease-free survival. In patients who respond to NAC, OS and DFS has been shown to be positive, with a reduced rate of EMV. PMID- 27695934 TI - The development of an ICF-based clinical guideline and screening tool for the standardized assessment and evaluation of functioning after head and neck cancer treatment. AB - The assessment and evaluation of functioning and quality of life after tumor treatment in head and neck cancer (HNC) are considered as essential aspects of clinical routine and studies. A huge number of instruments are available that have been designed to evaluate functioning and quality of life after HNC treatment. The diversity of these instruments in terms of content, response options and administration hinders the comparability of available studies and the performance of meta-analyses. The objective of this paper is to inform about the development of a screening tool for the standardized assessment and evaluation of functioning based on the International Classification of Functioning, Disability and Health (ICF) Core Set for HNC. We followed a multi-step approach including (1) preparatory studies to identify and preselect suitable instruments for the assessment of functioning, (2) a decision-making process to agree on an ICF-based clinical guideline including instruments assessing functioning and (3) the development of a computer-based standardized screening tool to assess and evaluate functioning based on this guideline in clinical routine. Twenty-one experts participated in a consensus meeting and decided on instruments to be included in an ICF-based clinical guideline and screening tool for the assessment and evaluation of functioning in HNC patients in cancer treatment. The chosen instruments cover all aspects of the ICF Core Set for HNC addressing therapy control, pain, food intake/swallowing, voice/speech/breathing, other somatic complaints and psychosocial aspects. The screening tool contains patient-reported outcome measures and a clinician's checklist. It has to be further tested in clinical practice. PMID- 27695936 TI - [Settings-based prevention of overweight in childhood and adolescents : Theoretical foundation, determinants and intervention planning]. AB - BACKGROUND: Childhood and adolescent overweight can still be seen as a global public health problem. Based on our socioeconomic understanding, overweight is the result of a complex interplay of a diverse array of factors acting on different levels. Hence, in addition to individual level determinants overweight prevention should also address environmental related factors as part of a holistic and integrated setting approach. OBJECTIVE: This paper aims to discuss the setting approach with regard to overweight prevention in childhood and adolescence. In addition to a summary of environmental factors and their empirical influence on the determinants of overweight, theoretical approaches and planning models of settings-based overweight prevention are discussed. RESULTS: While settings can be characterized as specific social-spatial subsystems (e. g. kindergarten, schools), living environments relate to complex subject-oriented environments that may include various subsystems. Direct social contexts, educational contexts and community contexts as relevant systems for young people contain different evidence-based influences that need to be taken into account in settings based overweight prevention. To support a theory-driven intervention, numerous planning models exist, which are presented here. DISCUSSION: Given the strengthening of environments for health within the prevention law, the underlying settings approach also needs further development with regard to overweigth prevention. This includes the improvement of the theoretical foundation by aligning intervention practice of planning models, which also has a positive influence on the ability to measure its success. PMID- 27695935 TI - Clinical response in a risperidone-medicated naturalistic sample: patients' characteristics and dose-dependent pharmacokinetic patterns. AB - The purpose of this study was to disentangle an association between plasma concentrations of risperidone (RIS), its active metabolite 9-hydroxyrisperidone (9-OH-RIS) and the active moiety, AM (RIS + 9-OH-RIS), and clinical response in a naturalistic sample. Plasma concentrations of RIS, 9-OH-RIS and AM in patients out of a therapeutic drug monitoring (TDM) database were compared between responders (n = 64) and non-responders (n = 526) using the Clinical Global Impressions (CGI) Scale. Daily dosage of risperidone did not differ between responders and non-responders. Differences for active moiety plasma levels between the two groups did not reach statistical significance. However, responders showed lower plasma concentrations of the parent compound RIS as well as lower metabolic ratios RIS/9-OH-RIS than non-responders (p = 0.017 and p = 0.034). These differences did not remain after controlling for age and baseline symptoms. Furthermore, the cohort was split into two subgroups based on the daily dosage: patients under high (>=6 mg/day) (R H, n = 187) and patients under lower dosages (<6 mg) (R L, n = 403) of risperidone. Differences between responders and non-responders after controlling for demographic and clinical characteristics remained only for plasma concentrations of active moiety in the lower-dose medicated groups; non-responders showed higher active moiety plasma concentrations than responders. Understanding the mechanisms involved and factors associated with the clinical response in patients medicated with antipsychotics is of great interest. Our data imply that clinical response to an antipsychotic treatment cannot be attributed to a single pharmacokinetic pattern. It seems to be rather a complex patchwork of influencing factors such as demographic and clinical characteristics as well as the metabolizer status as surrogate of CYP activity. It seems that the ratio between RIS and 9-OH-RIS may play a crucial role in mediating the clinical effect. PMID- 27695937 TI - [Influenza and community acquired pneumonia in German primary care]. AB - Influenza and community-acquired pneumonia (CAP) impose a considerable annual burden on the German primary care system. Yet there is a lack of epidemiological data from the country's outpatient sector on groups at risk as well as on the complications of these diseases.The Robert Koch Institute (RKI) initiated the study to identify population groups at increased risk for influenza or CAP as well as related comorbidities and sequelae. We present the methodology of the study and the descriptive analysis of the patients.ICD-10-based data was collected in 89 primary health care practices between January 2012 and April 2015 using a data extraction tool developed on behalf of the RKI. Case-based anonymized information was recorded for all patients in whom influenza, CAP or other acute respiratory infections (ARI) were diagnosed. For each patient information on all diagnoses including the date were retrospectively and prospectively collected (each for six months) as well as age, sex and influenza vaccination.Data on 156,803 patients with ARI was collected, of them 7909 patients with influenza (within influenza waves) and 8528 patients with CAP diagnoses. Influenza diagnoses showed a strong seasonal pattern and captured annual influenza waves in Germany. Of the influenza cases 1.6 % had a following diagnosis of CAP within 30 days. Age-specific prevalence of chronic diseases such as asthma and diabetes was significantly higher in the study population as compared to the German population.The developed tool delivers in a standardized fashion ICD-10-coded epidemiological data on population-based burden of influenza and CAP in Germany. As the descriptive analysis showed, the collected dataset is a reliable and solid basis for the further investigations of the study questions. PMID- 27695938 TI - [Social counseling in outpatient cancer counseling centers : Offers and use by advice-seekers]. AB - BACKGROUND: Outpatient psychosocial cancer care has gained importance in recent years and psychosocial counselling services (PCS) offer a broad spectrum of counselling interventions. Yet there is no published research on PCS legal counselling services. This study investigated the range of issues addressed by legal counselling and their relationship with characteristics of advice seekers and counsellors. METHODS: We analyzed the records of 21 PCS funded by the German Cancer Aid (DKH) including 5203 advice seekers (80 % patients, 20 % others including friends and family; age ? 54 years; 24 % male) in 20,947 counselling sessions. We calculated descriptive statistics and binary logistic regression analyses (legal counselling: yes/no). RESULTS: Fifty-five percent of counselling seekers received legal counselling and 28 % approached the PCS exclusively for legal counselling. The proportion of people seeking legal advice ranged from 15 to 87 % between counselling centers. The most common topics during legal counselling were medical rehabilitation programs (57 %) and disability law (43 %). Counselling occurred in a single session in 68 % of cases and was mostly sought by older and unemployed persons with a recent diagnosis. Legal counselling made up 18 % of counselling time. Legal advice was mostly given by social workers (71 %). CONCLUSIONS: Legal counselling is a major part of psychosocial care services. Our results reveal large differences between counselling centers. Further research on quality of care and efficacy of legal counseling is needed. PMID- 27695939 TI - [What are the determinants of childhood obesity? : A literature review as part of the project "Nationwide Monitoring of Childhood Obesity Determinants"]. AB - BACKGROUND: Obesity can impair health even in childhood and unfold negative health consequences through an individual's lifespan. In Germany, to date, a systematic and periodically updated synopsis of the multifaceted determinants of childhood obesity is lacking. In this paper, we present the results of a systematic literature review on childhood obesity determinants, which was conducted over the course of the implementation of nationwide monitoring. METHODS: The review was carried out in three steps. Initially, a search for etiological models of childhood obesity was conducted. Based on these results, a systematic review of reviews on childhood obesity determinants was carried out. Finally, the results were verified by taking international guidelines on childhood obesity into account. RESULTS: In total, 21 etiological models, 75 reviews and 7 guidelines were identified. Over 60 determinants were extracted from these publications and were summarized into the following categories: nutritional behavior, physical activity behavior, sleeping pattern, biological determinants and diseases, prenatal and early childhood determinants, psycho social determinants, food environment, moveability/walkability, setting and social environment, health promotion and prevention, socioeconomic, demographic, and sociocultural determinants. CONCLUSION: This review demonstrates the complex patterns of childhood obesity determinants in correspondence with a socio ecological approach. The review will form the basis for the monitoring-system "Nationwide Monitoring of Childhood Obesity Determinants", which will be implemented at the Robert Koch Institute by the end of 2017. PMID- 27695940 TI - Immunohistochemical and electronmicroscopic features of mesenchymal-to-epithelial transition in human developing, postnatal and nephrotic podocytes. AB - Differentiation of human podocytes starts with mesenchymal-to-epithelial transition (MET) of the metanephric mesenchyme into the S-shaped nephrons. During further development, differentiating podocytes regain mesenchyme-like cell characteristics by epithelial-to-mesenchymal transition (EMT), leading to formation of the terminally differentiated, non-dividing cell. Both MET and EMT processes involve changes in content and organization of cytoskeletal and actin filaments, accompanied by the increased glomerular vascularization. Here, we analyze and compare normal human developing, postnatal and nephrotic podocytes and glomeruli, using immunohistochemical and double immunofluorescent methods for detection of markers of cytoskeletal filaments (nestin, cytokeratin 10-CK10, vimentin and alpha-SMA), vasculogenesis (CD31 and VEGF) and podocyte function (receptor for advanced glycation end products, RAGE). In addition, electron microscopy is used to detect ultrastructural changes of the podocytes. Early metanephric cup mesenchyme expresses all investigated markers except alpha-SMA, which characterizes only surface mesenchymal cells. In differentiating podocytes and cells of Bowman's capsule (parietal podocytes) nestin decreases, vimentin increases, while CK10 gradually disappears. Increase in alpha-SMA is associated with blood vessels development, appearance of podocyte pedicles and slit diaphragm and loss of intercellular connections (zonulae adherentes). Increase in CD31 characterizes vascular glomerular tufts development, while decrease in RAGE expression accompanies normal podocyte differentiation. In congenital nephrotic syndrome of the Finnish type, dedifferentiated podocytes display changes in cytoskeletal filaments and depletion of podocyte pedicles, while glomerular vascular supply is diminished. Our data also suggest high potential of metanephric mesenchyme and parietal podocytes in possible regeneration of the damaged podocytes. PMID- 27695941 TI - Mortality-related risk factors and long-term survival after 4460 liver resections in Sweden-a population-based study. AB - PURPOSE: The objectives of this study were to analyze the outcome after hepatectomy and to identify contributing factors to mortality and long-term survival in a population-based setting. METHOD: A retrospective, nationwide register study was performed. All patients who underwent hepatectomy in Sweden between 2002 and 2011 were identified in the Swedish Hospital Discharge Registry using their unique personal identification numbers. This cohort was linked to the National Cancer Registry (cancer diagnosis), the National Registry of Causes of Death, and the Migration Registry. Survival analysis by Kaplan-Meier method was performed to assess long-term outcome. A Cox regression model was used to analyze risk factors affecting long-term survival. RESULTS: Overall, 4460 hepatectomies were performed. The 30- and 90-day mortalities were 1.8 and 3.1 %, respectively. The overall 5- and 10-year survival rates for all diagnoses were 45 and 38 %, respectively. Independent risk factors for 5-year mortality were as follows: patient age, comorbidity, male gender, intrahepatic/extrahepatic cholangiocarcinoma, gallbladder cancer, extent of hepatectomy, and hepatectomies performed at non-university hospitals. Re-resection (78.1 % with diagnosis "metastasis") was performed on 374 patients. In these patients, mortality risk decreased by >50 % (HR 0.42; 95 %, CI 0.33-0.53). CONCLUSION: In a population based analysis, liver resections are done with a low mortality risk and good long term outcome. Patients who underwent resection at a University Hospital showed a significant better outcome compared to patients resected at non-University Hospitals. These results support further centralization of liver surgery. Re resection should be performed if feasible. PMID- 27695942 TI - The development of anatomy: from macroscopic body dissections to stem cell derived organoids. AB - Anatomy as a descriptive topic of research and instruction in medicine has been increasingly influenced by discoveries in molecular cell and developmental biology and most recently the advent of human induced pluripotent stem cells and organoids. We summarize here how anatomy has been influenced by developmental and stem cell biologists, and how in vitro modelling of the three-dimensional body environment is emerging to understand structure and function of cells during differentiation processes in development and disease. PMID- 27695945 TI - Nominee and nominator, but never Nobel Laureate: Vincenz Czerny and the Nobel Prize. AB - PURPOSE: The Heidelberg surgeon Vincenz Czerny (1842-1916) is remembered as pioneer of innovative operations as well as entrepreneur of interdisciplinary cancer therapy. The purpose of this paper is to describe his role during the early history of the Nobel Prize in physiology or medicine. METHOD: Based on documents from the Nobel Archive, this paper investigates how Czerny contributed, both as nominee and nominator, in shaping the early years of Nobel Prize history. RESULTS: Vincenz Czerny was nominated at least three times for the Nobel Prize, but he was never selected. Czerny's own nomination letters pinpoint important trends in medicine around the turn of the century. At least seven of the candidates he put forward, became Nobel Laureates. CONCLUSION: Czerny-like many other internationally renowned surgeons during the first decades of the twentieth century-missed out on the Nobel Prize, partly because it is not a lifetime award and his work would have to have been more recent. However, with his nominations, Czerny helped to shape the Nobel Prize to become the most important scientific award worldwide. PMID- 27695944 TI - Endoscopic and clinical benefits of hyaluronic acid in children with chronic adenoiditis and middle ear disease. AB - Hyaluronic acid (HA) is involved in modulating inflammatory airway processes and mucociliary clearance. Some studies have tested the effectiveness of the topical administration of HA in patients with upper airway diseases with positive preliminary results. A prospective, single-blind, 1:1 randomised controlled study was performed to assess the efficacy and safety of the daily topical administration of 9 mg of sodium hyaluronate in 3 mL of a 0.9 % sodium saline solution on the basis of endoscopic and clinical parameters in children with chronic adenoiditis associated with recurrent acute otitis media and otitis media with effusion; age- and gender-matched children receiving normal 0.9 % sodium chloride saline solution were used as controls. Analysis was based on 103 (mean age 63.3 +/- 18.2 months; 52 males, 50.5 %) children: 54 in the study group and 49 in the control group. A statistically significant reduction in the mean number of all acute otitis media episodes (AOME) (mean reduction 0.8 +/- 0.4 per month; p value 0.05) and AOME without tympanic membrane perforation (mean reduction 0.6 +/- 0.3 per month; p value 0.04) after recruitment was documented only in the study group. HA significantly improved all the endoscopic outcomes (p values ranging between 0.05 and <0.01) but one. Nasal washing with saline solution was effective on only three of them (p values ranging between 0.03 and <0.01). No untoward effects were documented. Our results confirm the safety and document the positive effect of topically administered HA solution on children with chronic adenoiditis associated with middle ear disease. PMID- 27695943 TI - The role of CEA-related cell adhesion molecule-1 (CEACAM1) in vascular homeostasis. AB - Carcinoembryonic antigen (CEA)-related cell adhesion molecules belong to the immunoglobulin superfamily, are expressed in a broad spectrum of tissues and cell types and exert context-dependent activating as well as inhibitory effects. Among these molecules, the CEA-related cell adhesion molecule-1 (CEACAM1) is a transmembrane molecule with an extracellular, a transmembrane and a cytoplasmic domain. The latter contains immunoreceptor tyrosine-based inhibitory motifs and functions as a signaling molecule. CEACAM1 can form homo- and heterodimers which is relevant for its signaling activities. CEACAM1 acts as co-receptor that modulates the activity of different receptor types including VEGFR-2, and B and T cell receptors. CEACAM1 is expressed in endothelial cells, in pericytes of developing and newly formed immature blood vessels and in angiogenically activated adult vessels, e.g., tumor blood vessels. However, it is either undetectable or only weakly expressed in quiescent blood vessels. Recent studies indicated that CEACAM1 is involved in the regulation of the endothelial barrier function. In CEACAM1 -/- mice, increased vascular permeability and development of small atherosclerotic lesions was observed in the aortae. CEACAM1 is also detectable in activated lymphatic endothelial cells and plays a role in tumor lymphangiogenesis. This review summarizes the vascular effects of CEACAM1 and focuses on its role in vascular morphogenesis and endothelial barrier regulation. PMID- 27695946 TI - Browning of subcutaneous fat and higher surface temperature in response to phenotype selection for advanced endurance exercise performance in male DUhTP mice. AB - For the assessment of genetic or conditional factors of fat cell browning, novel and polygenic animal models are required. Therefore, the long-term selected polygenic mouse line DUhTP originally established in Dummerstorf for high treadmill performance is used. DUhTP mice are characterized by increased fat accumulation in the sedentary condition and elevated fat mobilization during mild voluntary physical activity. In the present study, the phenotype of fat cell browning of subcutaneous fat and a potential effect on oral glucose tolerance, an indicator of metabolic health, were addressed in DUhTP mice. Analysis of peripheral fat pads revealed increased brite (brown-in-white) subcutaneous adipose tissues and in subcutaneous fat from DUhTP mice higher levels of irisin and different markers of fat cell browning like T-box transcription factor (Tbx1), PPARalpha, and uncoupling protein (UCP1) (P < 0.05) when compared to unselected controls. UCP1 was further increased in subcutaneous fat from DUhTP mice in response to mild exercise (fourfold, P < 0.05). In addition, surface temperature of DUhTP mice was increased when compared to controls indicating a physiological effect of increased UCP1 expression. The present study suggests that DUhTP mice exhibit different markers of mitochondrial biogenesis and fat browning without external stimuli. At an age of 43 days, sedentary DUhTP mice have improved metabolic health as judged from lower levels of blood glucose after an oral glucose tolerance test. Consequently, the non-inbred mouse model DUhTP represents a novel model for the identification of fat cell browning mechanisms in white adipose tissues. PMID- 27695947 TI - L1CAM: amending the "low-risk" category in endometrial carcinoma. AB - PURPOSE: Low- and intermediate-risk endometrial carcinomas have an excellent prognosis. Nonetheless, a small subgroup of such patients will experience unexpected relapse. Recently L1CAM was suggested to be a strong prognosticator in endometrial carcinoma. The focus of our study was on low- and intermediate-risk disease, where no or only limited adjuvant treatment is recommended according to current guidelines. METHODS: Endometrial carcinomas of low, intermediate and high intermediate risk according to published 2016 consensus guidelines were identified. The study was limited to cases with previous central pathology review focusing on histotype, depth of myometrial invasion, presence of lymphovascular space invasion (LVSI) and MELF pattern of invasion. Standard L1CAM immunohistochemistry was performed. Disease-specific uni- and multivariate survival analyses were calculated. RESULTS: A total of 344 cases were available for immunohistochemistry (low-risk: n = 250; intermediate-risk: n = 67; high intermediate-risk: n = 27). L1CAM positivity rates were: 29/344 (8.4 %; all cases), 18/250 (7.2 %; low-risk), 6/67 (9.0 %; intermediate-risk) and 5/27 (18.5 %; high-intermediate-risk). Expression of L1CAM was independent of LVSI and MELF. L1CAM was a significant independent prognosticator for disease-specific survival with a hazard ratio of 5.98 [CI 1.50-22.14, p = 0.012]. Adverse prognostic significance of L1CAM positivity was maintained after low-risk subgroup analysis (5-year disease-specific survival rates 71.8 vs. 100 %, p < 0.0001). All four tumour-related deaths in the subgroup of low-risk disease occurred in patients with L1CAM-positive tumours. CONCLUSION: The current definition of "low-risk" in endometrial carcinoma should be amended. "Low-risk carcinomas" should be limited to L1CAM-negative tumours. L1CAM status will play a key role in future algorithms to tailor adjuvant treatment and patient follow-up strategies. PMID- 27695948 TI - Occult shunt infections-think of biofilms. PMID- 27695949 TI - Natural structural diversity within a conserved cyclic peptide scaffold. AB - We recently isolated and described the evolutionary origin of a diverse class of small single-disulfide bonded peptides derived from Preproalbumin with SFTI-1 (PawS1) proteins in the seeds of flowering plants (Asteraceae). The founding member of the PawS derived peptide (PDP) family is the potent trypsin inhibitor SFTI-1 (sunflower trypsin inhibitor-1) from Helianthus annuus, the common sunflower. Here we provide additional structures and describe the structural diversity of this new class of small peptides, derived from solution NMR studies, in detail. We show that although most have a similar backbone framework with a single disulfide bond and in many cases a head-to-tail cyclized backbone, they all have their own characteristics in terms of projections of side-chains, flexibility and physiochemical properties, attributed to the variety of their sequences. Small cyclic and constrained peptides are popular as drug scaffolds in the pharmaceutical industry and our data highlight how amino acid side-chains can fine-tune conformations in these promising peptides.

AB - Since the first rescue of a recombinant Newcastle disease virus (rNDV) in the late 1990s, many more rNDVs have been rescued by researchers around the world. Regardless of methodology, the main principle behind rescue of the virus has remained the same, i.e., the formation of a functional replication complex by simultaneously providing the full-length viral RNA and the viral NP, P and L proteins. However, different strategies have been reported for the insertion of the full-length genome into a suitable transcription vector, which remains the most challenging step of the rescue. Moreover, several systems have been published for provision of the DNA-dependent RNA polymerase, which is needed for transcription of viral RNA (vRNA) from the transfected plasmid DNA. The aim of this article is to consolidate all of the current cDNA assembly strategies and transcription systems used in rescue of rNDV in order to attain a better understanding of the advantages and disadvantages of each approach. PMID- 27695951 TI - Monitoring of influenza A viruses in wild bird populations in Kazakhstan in 2002 2009. AB - A comprehensive influenza virus monitoring study of wild birds was carried out at important flyway resting places and wintering sites in Kazakhstan over eight years. More than 3200 birds belonging to 155 species were sampled. Nearly three fourths of the birds belonged to the orders Anseriformes and Charadriiformes. In total, 118 hemagglutinating agents were isolated, and 95 of them were identified as influenza A viruses. The influenza viruses comprised eight different subtypes with a high prevalence of H13 and H3 viruses and also included low-pathogenic H5 viruses. The vast majority of the H13 viruses were isolated from members of the family Laridae, whereas the H3 viruses mostly originated from members of the family Anatidae, both in concordance with other monitoring studies. All virus isolates were recovered from cloacal swabs or fecal samples only. The influenza viruses were identified mainly in wetlands north of the Caspian Sea. These findings should be integrated in the design of further wild-bird-monitoring activities.

AB - The purpose of this article is to familiarize radiologists and clinicians with a subset of common and uncommon incidental findings on abdominal and pelvic computed tomography examinations, including hepatic, splenic, renal, adrenal, pancreatic, aortic/iliac arterial, gynecological, and a few other miscellaneous findings, with an emphasis on "incidentalomas" discovered in the emergency setting. In addition, we will review the complex problem of diagnosing such entities, and provide current management recommendations. Representative case examples, which we have encountered in our clinical practices, will be demonstrated. PMID- 27695952 TI - Multimodality imaging of placental masses: a pictorial review. AB - Placental masses are uncommonly identified at the time of obstetric ultrasound evaluation. Understanding the pathologies presenting as placental masses is key for providing a differential diagnosis and guiding subsequent management, which may include additional imaging with magnetic resonance (MR) imaging. Potential benign entities include chorioangiomas and teratomas. Larger chorioangiomas can cause fetal cardiovascular issues from volume overload. Placental mesenchymal dysplasia has an association with fetal anomalies and detailed fetal evaluation should be performed when it is suspected. Identifying other cystic masses such as partial and complete moles is crucial to prevent erroneous pregnancy termination. This review addresses normal imaging appearance of the placenta on ultrasound and MR imaging and describes various trophoblastic and nontrophoblastic placental masses. Potential placental mass mimics including uterine contractions and thrombo-hematomas are also presented. PMID- 27695954 TI - Can psychiatric childhood disorders be due to inborn errors of metabolism? AB - Many patients who visit a centre for hereditary metabolic diseases remarkably also suffer from a child psychiatric disorder. Those child psychiatric disorders may be the first sign or manifestation of an underlying metabolic disorder. Lack of knowledge of metabolic disorders in child psychiatry may lead to diagnoses being missed. Patients therefore are also at risk for not accessing efficacious treatment and proper counselling. To search the literature for the co-occurrence of child psychiatric disorders, such as ADHD, autism, psychosis, learning disorders and eating disorders and metabolic disorders. A search of the literature was conducted by performing a broad search on PubMed, using the terms "ADHD and metabolic disorders", "autism and metabolic disorders", "psychosis and metabolic disorders", "learning disorders and metabolic disorders", and "eating disorders and metabolic disorders". Based on inclusion criteria (concerning a clear psychiatric disorder and concerning a metabolic disorder) 4441 titles and 249 abstracts were screened and resulted in 71 relevant articles. This thorough literature search provides child and adolescent psychiatrists with an overview of metabolic disorders associated with child psychiatric symptoms, their main characteristics and recommendations for further investigations. PMID- 27695955 TI - Light-curing units used in dentistry: factors associated with heat development potential risk for patients. AB - OBJECTIVES: To investigate how heat development in the pulp chamber and coronal surface of natural teeth with and without cusps subjected to irradiance using light-emitting diode (LED)-light-curing units (LCUs) is associated with (i) irradiance, (ii) time, (iii) distance, and (iv) radiant exposure. MATERIALS AND METHODS: Three different LED-LCUs were used. Their irradiance was measured with a calibrated spectrometer (BlueLight Analytics Inc., Halifax, Canada). An experimental rig was constructed to control the thermal environment of the teeth. The LED-LCU tip position was accurately controlled by a gantry system. Tooth surface temperature was measured by thermography (ThermaCAM S65 HS, FLIR Systems, Wilsonville, USA) and pulp chamber temperature with a thermocouple. LED-LCU tip distance and irradiation times tested were 0, 2, and 4 mm and 10, 20, and 30 s, respectively. Ethical permission was not required for the use of extracted teeth. RESULTS: Maximum surface and pulp chamber temperatures were recorded in tooth without cusps (58.1 degrees C +/- 0.9 degrees C and 43.1 degrees C +/- 0.9 degrees C, respectively). Radiant exposure explained the largest amount of variance in temperature, being more affected by time than irradiance. CONCLUSIONS: At all combinations of variables tested, repeated measurements produced consistent results indicating the reliability of the method used. Increased exposure time seems to be the factor most likely to cause tissue damage. CLINICAL RELEVANCE: Risk of superficial tissue damage at irradiances >1200 mW/cm2 is evident. There is a risk of pulp damage when only thin dentin is left at higher irradiances (>1200 mW/cm2). Clinicians should be aware of LED-LCU settings and possible high temperature generated. PMID- 27695957 TI - Humoral immune responses and viral shedding following vaccination with modified live porcine reproductive and respiratory syndrome virus vaccines. AB - The antibody response and pattern of shedding of vaccine virus following vaccination with modified live genotype I or II porcine reproductive and respiratory syndrome virus (PRRSV) vaccines (MLVs) were investigated. Ninety PRRSV-free pigs were divided randomly seven, groups including the NEG, EU1, EU2, US1, US2, US3 and US4 groups. The NEG group was unvaccinated. The EU1, EU2, US1, US2, US3 and US4 groups were vaccinated with the following MLVs: AMERVAC(r) PRRS, Porcillis(r) PRRS, FosteraTM PRRS, Ingelvac(r) PRRS MLV, Ingelvac(r) PRRS ATP, and PrimePacTM PRRS+ , respectively. Sera were quantitatively assayed for viral RNA using qPCR. Antibody responses were measured using Idexx ELISA and serum neutralization (SN). Shedding of vaccine virus was investigated using sentinel pigs and by detection of viral RNA in tonsil scrapings. Antibody responses were detected by ELISA at 7-14 days post-vaccination (DPV) and persisted at high titers until 84 DPV in all MLV groups. The SN titers were delayed and isolate specific. SN titers were higher for the homologous virus than for heterologous viruses. Age-matched sentinel pigs introduced into the EU2, US2 and US3 groups at 60 DPV seroconverted. In contrast, sentinel pigs introduced at 84 DPV remained negative in all of the MLV groups. Vaccine viral RNA was detected in tonsil scrapings from the EU2, US2 and US3 groups at 84-90 DPV. No viral RNA was detected beyond 70 DPV in the EU1, US1 and US4 groups. In conclusion, all MLV genotypes induced rapid antibody responses, which were measured using ELISA. The development of SN antibodies was delayed and isolate-specific. However, the shedding pattern was variable and depended on the by virus isolate used to manufacture the vaccine. PMID- 27695958 TI - Dengue scenario: Chennai perspective-a six-year study (2009-2014). AB - Dengue is a public health problem with an increasing global incidence and geographic distribution in almost all tropical and subtropical countries, with a transition from epidemic to endemic occurrence. In this study, we report a six year analysis (2009-2014) performed at the Department of Virology, King Institute of Preventive Medicine, Chennai, Tamil Nadu, India. Our data confirm earlier findings that dengue is highly endemic in Chennai. In the present study, 10,099 serum samples from suspected dengue cases were tested for IgM ELISA (NIV Capture) and IgG Panbio ELISA (Australia). Of these suspected cases 6,798 and 3,301 were pediatric and adult cases, respectively, and 1,927 (19.08 %) were confirmed serologically as dengue. Of these, 1,752 (25.7 %) and 175 (5.3 %) were pediatric and adult cases, respectively. The aim of this study was to highlight the occurrence of DHF and DSS, mainly among the pediatric population, in which the infection causes higher mortality and morbidity. The overall positivity was higher in the pediatric group than in the adults. Detection of both IgM and IgG positivity will be useful for monitoring infection rates, the disease spectrum, and the prevalence of the different serotypes, which will give us insight about the circulating serotypes and pathogenicity. These data will be valuable for providing an early warning to predict an impending epidemic leading to major clinical manifestations of DHF and DSS. PMID- 27695956 TI - Octreotide ameliorates inflammation and apoptosis in acute and kindled murine PTZ paradigms. AB - In the present study, the role of octreotide (OCT) in pentylenetetrazole (PTZ) kindling as well as in acute convulsion models was evaluated. Mice were allocated in groups as (1) control saline; (2) acute PTZ (PTZ-a; 60 mg/kg, i.p.), as a single convulsive dose; and (3) kindled (PTZ-k) receiving nine subconvulsive doses of PTZ (40 mg/kg, i.p.) for 17 days. Groups 4-7 received either valproic acid (VPA) 50 mg/kg or OCT (50 MUg/kg, Sandostatin(r)) 30 min by oral gavage before PTZ-a or PTZ-k. The median seizure stage, latency onset of first stage 4/5 seizures, and incidence of convulsing animals were recorded. Cortical dopamine (DA), tumor necrosis factor (TNF)-alpha, interleukin (IL)-10, caspase (Casp)-3, myeloperoxidase (MPO), and nitric oxide (NO) were assessed in addition to inducible nitric oxide synthase (iNOS) that was evaluated immunohistochemically in a different set of groups. OCT halted PTZ-induced epilepsy delaying convulsion latency via modulating MPO and TNF-alpha and normalizing IL-10 with both treatment regimens. In PTZ-k, it decreased Casp-3 activity, NO level, and iNOS immunoreactivity. OCT in both paradigms decreased DA concentration. The current investigation implicates a crucial role for OCT in modulating PTZ-induced kindling by regulating inflammatory and apoptotic effects. PMID- 27695959 TI - Transanal total mesorectal excision: dissection tips using 'O's and 'triangles'. AB - PURPOSE: Transanal total mesorectal excision (taTME) requires specific technical expertise, as it is often difficult to ascertain the correct dissection plane. Consequently, one can easily enter an incorrect plane, potentially resulting in bleeding (sidewall or presacral vessels), autonomic nerve injury and urethral injury. We aim to demonstrate specific visual features, which may be encountered during surgery and can guide the surgeon to perform the dissection in the correct plane. METHOD: Specific features of dissection in the correct and incorrect planes are demonstrated in the accompanying video. RESULTS: The 'triangles' created using appropriate traction can aid in performing a precise dissection in the correct plane. Recognition of features described as 'O's can alert surgeons that they are entering a new fascial plane and can avoid incursion into an incorrect plane. CONCLUSION: Understanding and recognizing the described features which can be encountered in taTME surgery, a safe and accurate TME dissection can be facilitated. PMID- 27695960 TI - Mortality from solid cancers other than lung, liver, and bone in relation to external dose among plutonium and non-plutonium workers in the Mayak Worker Cohort. AB - Exposure to ionizing radiation has well-documented long-term effects on cancer rates and other health outcomes in humans. While in vitro experimental studies had demonstrated that the nature of some radiation effects depend on both total dose of the radiation and the dose rate (i.e., the pattern of dose distribution over time), the question of whether or not the carcinogenic effect of radiation exposure depends on the dose rate remains unanswered. Another issue of interest concerns whether or not concomitant exposure to external gamma rays and inhaled plutonium aerosols has any effect on the external exposure effects. The analyses of the present paper focus on the risk of solid cancers at sites other than lung, liver, and bone in Mayak workers. Recent findings are reviewed indicating that there is no evidence of plutonium dose response for these cancers in the Mayak worker cohort. Then the evidence for differences in the external dose effects among workers with and without the potential for exposure to alpha particles from inhaled plutonium is examined. It is found that there is no evidence that exposure to plutonium aerosols significantly affects the risk associated with external exposure. While the Mayak external dose risk estimate of an excess relative risk of 0.16 per Gy is somewhat lower than an appropriately normalized risk estimate from the Life Span Study of Japanese atomic bomb survivors, the uncertainties in these estimates preclude concluding that the external dose excess relative risks of this group of solid cancers differ in the two cohorts. PMID- 27695961 TI - Targeted proteomics for the indirect detection of dexamethasone treatment in bovines. AB - The illegal use of pharmacologically active compounds for growth promotion in food-producing species poses risks for consumer health and animal welfare. Surveillance relies on the quantification of drug residues in animal fluids or tissues, but the efficacy can be negatively affected due to undetectable residual concentrations in biological matrices. Consequently, techniques focusing on the indirect biological effects of exogenous compound administration have been proposed as more sensitive detection methods. The purpose of the present study is to develop a tandem mass spectrometry analytical method based on low-energy collision-induced dissociation (CID-MS/MS) using multiple reaction monitoring (MRM) for the quantification of 12 potential protein markers of skeletal muscle to detect anabolic treatments with dexamethasone. Protein markers identified in a previous study applying a 2D-DIGE proteomics approach have been quantified using the signature peptide method. A group of proteins were confirmed as reliable markers. Quantitative results enabled a predictive model to be defined based on logistic regression for the detection of treated animals. The developed model was finally cross-validated in an independent animal set. Graphical abstract Analytical workflow used for the quantification of indirect protein markers of dexamethasone treatment. PMID- 27695963 TI - Quantification of antibody coupled to magnetic particles by targeted mass spectrometry. AB - Quantifying the amount of antibody on magnetic particles is a fundamental, but often overlooked step in the development of magnetic separation-based immunoaffinity enrichment procedures. In this work, a targeted mass spectrometry (MS)-based method was developed to directly measure the amount of antibody covalently bound to magnetic particles. Isotope-dilution liquid chromatography tandem MS (ID-LC-MS/MS) has been extensively employed as a gold-standard method for protein quantification. Here, we demonstrate the utility of this methodology for evaluating different antibody coupling processes to magnetic particles of different dimensions. Synthesized magnetic nanoparticles and pre-functionalized microparticles activated with glutaraldehyde or epoxy surface groups were used as solid supports for antibody conjugation. The key steps in this quantitative approach involved an antibody-magnetic particle coupling process, a wash step to remove unreacted antibody, followed by an enzymatic digestion step (in situ with the magnetic particles) to release tryptic antibody peptides. Our results demonstrate that nanoparticles more efficiently bind antibody when compared to microparticles, which was expected due to the larger surface area per unit mass of the nanoparticles compared to the same mass of microparticles. This quantitative method is shown to be capable of accurately and directly measuring antibody bound to magnetic particles and is independent of the conjugation method or type of magnetic particle. Graphical Abstract Schematic illustration of the isotope-dilution mass spectrometry-based workflow to directly measure antibody bound to magnetic particles (MP). PMID- 27695962 TI - Isotope-targeted glycoproteomics (IsoTaG) analysis of sialylated N- and O glycopeptides on an Orbitrap Fusion Tribrid using azido and alkynyl sugars. AB - Protein glycosylation is a post-translational modification (PTM) responsible for many aspects of proteomic diversity and biological regulation. Assignment of intact glycan structures to specific protein attachment sites is a critical step towards elucidating the function encoded in the glycome. Previously, we developed isotope-targeted glycoproteomics (IsoTaG) as a mass-independent mass spectrometry method to characterize azide-labeled intact glycopeptides from complex proteomes. Here, we extend the IsoTaG approach with the use of alkynyl sugars as metabolic labels and employ new probes in analysis of the sialylated glycoproteome from PC 3 cells. Using an Orbitrap Fusion Tribrid mass spectrometer, we identified 699 intact glycopeptides from 192 glycoproteins. These intact glycopeptides represent a total of eight sialylated glycan structures across 126 N- and 576 O glycopeptides. IsoTaG is therefore an effective platform for identification of intact glycopeptides labeled by alkynyl or azido sugars and will facilitate further studies of the glycoproteome.

PMID- 27695964 TI - Killer immunoglobulin-like receptor (KIR) and KIR-ligand genotype do not correlate with clinical outcome of renal cell carcinoma patients receiving high dose IL2. AB - NK cells play a role in many cancer immunotherapies. NK cell activity is tightly regulated by killer immunoglobulin-like receptor (KIR) and KIR-ligand interactions. Inhibitory KIR-ligands have been identified as HLA molecules, while activating KIR-ligands are largely unknown. Individuals that have not inherited the corresponding KIR-ligand for at least one inhibitory KIR gene are termed the "KIR-ligand missing" genotype, and they are thought to have a subset of NK cells that express inhibitory KIRs for which the corresponding KIR-ligand is missing on autologous tissue, and thus will not be inhibited through KIR-ligand recognition. In some settings where an anticancer immunotherapeutic effect is likely mediated by NK cells, individuals with a KIR-ligand missing genotype have shown improved clinical outcome compared to individuals with an "all KIR-ligands present" genotype. In addition, patients receiving hematopoietic stem cell transplants for leukemia may do better if their donor has more activating KIR genes (i.e., KIR haplotype-B). In a recent multi-institution clinical trial of patients with metastatic renal cell carcinoma receiving high-dose IL2 (HD-IL2), 25 % of patients showed a complete or partial tumor response to this therapy. We genotyped KIR and KIR-ligand genes for these patients (n = 107) and tested whether KIR/KIR-ligand genotypes correlated with patient clinical outcomes. In these analyses, we did not find any significant association of KIR/KIR-ligand genotype (either KIR-ligand missing or the presence of KIR haplotype-B) with patient outcome in response to the HD-IL2 therapy.

AB - Meandering right pulmonary vein is a rare vascular anomaly that requires accurate diagnosis to avoid unnecessary procedures and unintended vascular injury during operation. We describe an unusual meandering right upper lobe pulmonary vein draining into the left atrium via the right middle lobe pulmonary vein. PMID- 27695967 TI - Surfactant-induced bacterial community changes correlated with increased polycyclic aromatic hydrocarbon degradation in contaminated soil. AB - Bioremediation as a method for removing polycyclic aromatic hydrocarbons (PAHs) from contaminated environments has been criticized for poor removal of potentially carcinogenic but less bioavailable high molecular weight (HMW) compounds. As a partial remedy to this constraint, we studied surfactant addition at sub-micellar concentrations to contaminated soil to enhance the biodegradation of PAHs remaining after conventional aerobic bioremediation. We demonstrated increased removal of four- and five-ring PAHs using two nonionic surfactants, polyoxyethylene(4)lauryl ether (Brij 30) and polyoxyethylene sorbitol hexaoleate (POESH), and analyzed bacterial community shifts associated with those conditions. Eight groups of abundant bacteria were implicated as potentially being involved in increased HMW PAH removal. A group of unclassified Alphaproteobacteria and members of the Phenylobacterium genus in particular showed significantly increased relative abundance in the two conditions exhibiting increased PAH removal. Other implicated groups included members of the Sediminibacterium, Terrimonas, Acidovorax, and Luteimonas genera, as well as uncharacterized organisms within the families Chitinophagaceae and Bradyrhizobiaceae. Targeted isolation identified a subset of the community likely using the surfactants as a growth substrate, but few of the isolates exhibited PAH-degradation capability. Isolates recovered from the Acidovorax and uncharacterized Bradyrhizobiaceae groups suggest the abundance of those groups may have been attributable to growth on surfactants. Understanding the specific bacteria responsible for HMW PAH removal in natural and engineered systems and their response to stimuli such as surfactant amendment may improve bioremediation efficacy during treatment of contaminated environmental media.

PMID- 27695969 TI - Fenestration of the supraclinoid internal carotid artery arising from the paraclinoid aneurysmal dilatation and fusing with the origin of the posterior communicating artery: a case report. AB - We report an extremely rare case of fenestration of the supraclinoid internal carotid artery (ICA) diagnosed by magnetic resonance (MR) angiography. The smaller channel arose from the paraclinoid ICA aneurysmal dilatation, and the posterior communicating artery arose from the distal end of the fenestration. Careful observation of MR angiographic images, including source images, is important to detect rare arterial variations, and their identification on MR angiography is aided by the creation of partial maximum-intensity-projection images and partial volume-rendering images. PMID- 27695971 TI - Patient-specific factors influencing the traction forces in hip arthroscopy. AB - INTRODUCTION: The application of traction in hip arthroscopy is associated with peri-operative complications. Within a therapeutic case series, patient-related factors correlating with high-traction forces during hip arthroscopy and occurring complications should be identified. MATERIALS AND METHODS: In 30 male and 38 female patients (mean age: 44.5 years), intra-operative traction forces were monitored continuously using a specialised measurement device. A multivariate analysis was employed to identify patient-related factors influencing the traction force. Peri-operative complications (follow-up: 12 weeks) were evaluated by performing a single-case analysis. RESULTS: The mean initial force prior to penetration of the capsule ("initial force") was 477 N (men: 517 N; women: 444 N), decreasing after capsulotomy by an average of 17 %. The male gender (p < 0.001), Kellgren and Lawrence radiographic stage (p = 0.037), low minimum joint-space width (p = 0.029) and high body height/weight (p = 0.003/0.037) correlated significantly with higher distraction forces. The patient age and type of anaesthesia (general versus spinal) were not relevant. Complications were observed in ten patients on the first post-operative day. In two of these patients a partial sensory deficit of the lateral cutaneous femoral nerve persisted after 12 weeks. All patients with complications required initial traction forces of >400 N. CONCLUSIONS: The study revealed several patient specific risk factors correlating with high-traction forces during hip arthroscopy. With view to potential complications, these patient groups require special attention during surgical treatment as well as in future studies. PMID- 27695972 TI - Aliskiren decreases oxidative stress and angiogenic markers in retinal pigment epithelium cells. AB - There is growing evidence on the role of ocular renin-angiotensin system (RAS) in the development of diabetic retinopathy (DR), particularly due to the trigger of oxidative stress and angiogenesis. Despite this there is no effective RAS-based therapy in DR capable of preventing retinal damage induced by RAS activation. We recently described that retinal pigment epithelium (RPE) cells express the main components of the RAS. We here propose to investigate the role of glucose upon the retinal RAS and whether aliskiren, a direct renin inhibitor, protects RPE cells from angiogenesis and oxidative stress. RPE cells were chosen as target since one of the first events in DR is the dysfunction of the RPE retinal layer, which as a key function in maintaining the integrity of the retina. We found that the RAS present in the RPE cells was deregulated by hyperglycemic glucose concentrations. Exposure of RPE cells to angiotensin II increased the levels of the main pro-angiogenic factor, vascular endothelial growth factor (VEGF) in a concentration-dependent manner. Additionally, angiotensin II also stimulated the production of reactive oxygen species in RPE cells. Treatment of RPE cells with aliskiren decreased the levels of oxidative stress and promoted the expression of anti-angiogenic factors such as the pigment epithelium-derived factor and the VEGF165b isoform. Our findings demonstrate that the RAS is deregulated in hyperglycemic conditions and that aliskiren successfully protected RPE cells from RAS over activation. These anti-angiogenic and antioxidant properties described for aliskiren over RPE cells suggest that this drug has potential to be used in the treatment of diabetic retinopathy. PMID- 27695973 TI - Is gastroscopy for fecal immunochemical test positive patients worthwhile? AB - BACKGROUND: The use of fecal immunochemical test (FIT) in the screening for colorectal cancer is long established. However, more than 50 % of patients with positive FITs have a negative colonoscopy. The role of a subsequent oesophago gastro-duodenoscopy (OGD) is debatable. The aim of this study is to evaluate the yield of OGD in patients with positive FITs. METHODOLOGY: A retrospective review of patients who underwent colonoscopy for a positive FIT between Jan. 2008 and Dec. 2012 was identified from a prospectively collected endoscopy database at the National University Hospital, Singapore. Patients who underwent concurrent or subsequent OGDs for positive FIT formed the study group. We considered any new cancer or significant upper gastrointestinal pathology such as peptic ulcer disease or gastritis requiring treatment as a positive examination. RESULTS: A total of 202 patients underwent both a colonoscopy and an OGD for a positive FIT and formed the study group. One hundred and six (52.5 %) of them had a positive examination with gastritis and duodenitis representing the most common UGI pathology in 89 (44.1 %) patients. Twenty-nine (14.4 %) patients tested positive for helicobacter pylori infection and another 16 (7.9 %) patients had peptic ulcer disease. There were no UGI cancers detected. One patient had an esophageal leiomyoma that was treated conservatively. CONCLUSION: Routine gastroscopy for FIT positivity has a high diagnostic yield for benign upper gastrointestinal pathology. Well-designed prospective studies to further evaluate the cost effectiveness of routine gastroscopy in the work up of FIT positivity are warranted to make better clinical practice guidelines. PMID- 27695974 TI - Gastrointestinal tract anastomoses with the biofragmentable anastomosis ring: is it still a valid technique for bowel anastomosis? Analysis of 203 cases and review of the literature. AB - PURPOSE: Biofragmentable anastomosis ring (BAR) is an alternative to manual and stapled anastomoses performed within the upper and lower gastrointestinal (GI) tract. The aim of this study was to evaluate the effectiveness of BAR utility for bowel anastomoses based on our own material. METHODS: A retrospective analysis was performed to a total of 203 patients who underwent bowel surgery with the use of BAR anastomosis within upper and lower gastrointestinal tract between 2004 and 2014. Data for the analysis was collected based on medical records, treatment protocols, and the results of histological examinations. RESULTS: The study group consisted of 86 women and 117 men. The most common underlying pathology was a malignant disease (n = 165). Biofragmentable anastomosis ring (BAR) size 31 was the most commonly used (n = 87). A total of 169 colocolic or colorectal anastomoses and 28 ileocolic and 8 enteroenteric anastomoses were performed. The mortality rate was 0.5 % (n = 1) whereas re-surgery rate within 30 days was 8.4 % (n = 17). Twenty-eight patients developed perioperative complications with surgical site infection as the most common one (n = 11). Eight patients developed specific complications associated with BAR including an anastomotic leak (n = 6) and intestinal obstruction (n = 2). The mean time of hospital stay after surgery was 12.7 days. CONCLUSIONS: The use of BAR for the GI tract anastomoses is simple and rapid method and it is characterized with an acceptable number of perioperative mortality and complication rates. Based on our experience, we recommend the use of BAR anastomosis in different types of intestinal anastomosis in varying clinical scenarios. PMID- 27695975 TI - Long-term response to gluten-free diet as evidence for non-celiac wheat sensitivity in one third of patients with diarrhea-dominant and mixed-type irritable bowel syndrome. AB - PURPOSE: Irritable bowel syndrome (IBS) is common but therapies are unsatisfactory. Food is often suspected as cause by patients, but diagnostic procedures, apart from allergy testing, are limited. Based on the hypothesis of non-celiac wheat sensitivity (WS) in a subgroup of IBS patients, we tested the long-term response to a gluten-free diet (GFD) and investigated HLA-DQ2 or -DQ8 expression as a diagnostic marker for WS in diarrhea-dominant (IBS-D) and mixed type IBS (IBS-M). METHODS: The response to a GFD served as reference test for WS and HLA-DQ2/8 expression was determined as index test. Patients were classified as responders if they reported complete or considerable relief of IBS symptoms on at least 75 % of weeks over a 4-month period of gluten-free diet. Established questionnaires (IBS-Quality of Life (IBS-QoL), IBS Symptom Severity Scale (IBS SSS), European Quality of Life-5 Dimensions (EQ-5D)) were used for secondary outcome measures. RESULTS: Thirty-five patients finished the study. Of these, 12 (34 %) were responders and classified as having WS (95 % CI 21-51 %). HLA-DQ2/8 expression had a specificity of 52 % (95 % CI 33-71 %) and sensitivity of 25 % (95 % CI 8-54 %) for WS. Responders showed improvement in quality of life and symptom scores. At 1-year follow-up, all responders and 55 % of non-responders were still on GFD and reported symptom relief. CONCLUSION: Using strict criteria as recommended for IBS studies, about one third of patients with IBS-D or IBS-M are wheat sensitive, with a similar proportion in both IBS types. Expression of HLA-DQ2/8 is not useful as diagnostic marker for WS. Long-term adherence to a GFD is high and can sustain symptomatic improvement. PMID- 27695976 TI - Long-term functional follow-up after anterior rectal resection for cancer. AB - PURPOSE: This is a retrospective analysis including all of the patients that have undergone anterior resection for rectal cancer from January 1998 to December 2005 in two tertiary referral centers. The study aims to evaluate the long term functional results after low anterior resection and to identify the risk factors of postoperative bowel disorders. METHOD: Data were collected from the clinical records, and then the low anterior resection syndrome score which is a specific questionnaire to investigate the symptoms after surgery was submitted to the selected patients. Exclusion criteria were intra-abdominal rectal cancer, partial mesorectal excision, permanent stoma, recurrent local disease, and patients who declined the questionnaire. RESULTS: A total of 93 patients were included in the analysis with a median age at the diagnosis of 66 years. The median follow-up was 13.7 years, and low anterior resection syndrome was reported in 44 patients (47.5 %), with major manifestations in 19 patients (20.5 %), and minor symptoms in 25 patients (27 %). Age more than 70 years, tumor distance from the external anal verge, neoadjuvant treatment, and interval time of closing stoma are independent prognostic factors of functional disorders after surgery. CONCLUSIONS: Because of its great impact on the quality of life of these patients, it is necessary to early identify the syndrome trying to reduce its manifestations. Moreover, the symptoms seem to remain stable 1 year after surgery; hence, it is important to have an exhaustive, preoperative counseling and an integrated post-operative functional and rehabilitational follow-up in association with the oncologic pathway. PMID- 27695977 TI - Evaluation of lymph flow patterns in splenic flexural colon cancers using laparoscopic real-time indocyanine green fluorescence imaging. AB - PURPOSE: The treatment of splenic flexural colon cancer is not standardized because the lymphatic drainage is variable. The aim of this study is to evaluate the lymph flow at the splenic flexure. METHODS: From July 2013 to January 2016, consecutive patients of the splenic flexural colon cancer with a preoperative diagnosis of N0 who underwent laparoscopic surgery were enrolled. Primary outcome is frequency of the direction of lymph flow from splenic flexure. We injected indocyanine green (2.5 mg) into the submucosal layer around the tumor and observed lymph flow using the laparoscopic near-infrared camera system in 30 min after injection. RESULTS: Thirty-one patients were enrolled in this study. The lymph flow was visualized in 31 patients (100 %) without any complications. No case exhibited lymph flow in both the left colic artery (LCA) and left branch of the middle colic artery (lt-MCA) areas. There were 19 cases (61.3 %) with lymph flow directed to the area of the root of the inferior mesenteric vein (IMV), regardless of the presence of the left accessory aberrant colic artery. Lymph node metastases were observed in six cases (19.4 %), and all of the involved lymph nodes existed in lymph flow areas determined by real-time indocyanine green fluorescence imaging. CONCLUSIONS: The findings of the lymph flow pattern of splenic flexure suggest that lymph node dissection at the root of the IMV area is important, and it may be not necessary to ligate both the lt-MCA and LCA, at least in cases without widespread lymph node metastases. PMID- 27695979 TI - Aging and the effects of a half marathon on Achilles tendon force-elongation relationship. AB - PURPOSE: We aimed to determine whether there are different changes in Achilles tendon (AT) mechanical properties in middle-aged, compared to younger runners that might indicate that tendon fatigue, induced by long-distance running, is age dependent. METHODS: 27 middle-aged (50-67 years) and 22 younger (21-29 years) participants ran a 21 km route at their own pace (mean and SD: old: 3.1 +/- 0.3 m s-1; young: 3.6 +/- 0.5 m s-1). We tested for changes in the AT force-elongation relationship using dynamometry and ultrasonography during isometric voluntary ankle plantarflexion ramp contractions, conducted 20-28 h pre-run, immediately pre-run, immediately post-run and 20-28 h post-run. Stride frequency and number were examined to estimate cyclic tensile loading characteristics of the tendon during running. RESULTS: Muscle strength decreased significantly (P < 0.05) in both groups immediately post-run (old: 17 %; young: 11 %) and recovered to baseline within 20-28 h post-run. AT stiffness did not change for the younger adults, whereas the middle-aged adults showed a significant (P < 0.05) decrease in AT stiffness (22 %). However, tendon stiffness recovered to baseline 20-28 h post-run. Middle-aged, compared to young adults, demonstrated significantly (P < 0.05) greater stride frequency and number, but no correlations with tendon fatigue changes were determined (R 2 <= 0.038). CONCLUSIONS: The results suggest that the plasticity of the AT in response to short-term mechanical loading may be age dependent and that the AT length-tension properties of middle-aged runners may be more vulnerable to change following running compared to younger athletes. However, the observed AT changes in the middle-aged runners dissipated within 20 28 h post-run, suggesting that a tendon viscoelastic recovery mechanism may occur in vivo. PMID- 27695978 TI - Differential vascular reactivity responses acutely following ingestion of a nitrate rich red spinach extract. AB - INTRODUCTION: Inorganic nitrate ingestion has been posited to affect arterial blood pressure and vascular function. PURPOSE: We sought to determine the acute effect of a red spinach extract (RSE) high in inorganic nitrate on vascular reactivity 1-h after ingestion in peripheral conduit and resistance arteries. METHODS: Fifteen (n = 15; males 8, females 7) apparently healthy subjects (aged 23.1 +/- 3.3 years; BMI 27.2 +/- 3.7 kg/m2) participated in this crossover design, double-blinded study. Subjects reported to the lab >=2-h post-prandial and consumed RSE (1000 mg dose; ~90 mg nitrate) or placebo (PBO). Venipuncture was performed on three occasions: baseline, 30-min post-ingestion and between 65 to 75-min post-ingestion. Baseline vascular measurements [i.e., calf venous occlusion plethysmography, brachial artery flow-mediated dilation (FMD)], 30-min of continuous blood pressure (BP) and heart rate (HR) analysis, and follow-up vascular measurements beginning at 40-min post-ingestion were also performed. RESULTS: Humoral nitrate following RSE ingestion was significantly higher at 30- (+54 %; P = 0.039) and 65 to 75-min post-ingestion compared to baseline (+255 %, P < 0.001) and PBO at the same time points (P < 0.05). No significant changes in BP or HR occurred in either condition. Peak reactive hyperemia (RH) calf blood flow increased significantly (+13.7 %; P = 0.016) following RSE ingestion, whereas it decreased (-14.0 %; P = 0.008) following PBO ingestion. No significant differential FMD responses were detected (P > 0.05), though RH was decreased following the baseline measure in both conditions. CONCLUSIONS: RSE significantly increased plasma nitrate 30-min post-ingestion, but acute microvascular (i.e., resistance vasculature) reactivity increases were isolated to the lower limb and no appreciable change in brachial artery FMD was observed. PMID- 27695980 TI - Effects of caffeine ingestion on endurance performance in mentally fatigued individuals. AB - PURPOSE: To examine the effects of caffeine ingestion on physiological and perceptual responses in mentally fatigued individuals. METHODS: Eight male physically active subjects completed four cycling constant-workload tests in four experimental conditions at 80 % of maximal power output: control (C), mental fatigue (MF), mental fatigue plus caffeine ingestion (5 mg/kg) (MF-CAF), and mental fatigue plus placebo (MF-PLA). The mental fatigue was induced by a continuous performance task A-X version (AX-CPT). Before and after the AX-CPT, the profile of mood state (POMS) and blood samples for lactate measurement were collected. Oxygen consumption ([Formula: see text]), rating of perceived exertion (RPE), and electromyography (EMG) activity were measured during the cycling test. RESULTS: The time to exhaustion in C, MF, MF-PLA, and MF-CAF were 251 +/- 30, 222 +/- 23, 248 +/- 28, and 285 +/- 42 s, respectively. Delta values (corrected by C condition) were higher in MF-CAF than MF (P = 0.031). MF-CAF reported higher Vigor scores when compared with C (P = 0.046) and MF (P = 0.020). RPE at the first minute was significantly higher in MF-PLA than in C (P = 0.050); at the second minute, RPE was higher in MF-PLA than in C (P = 0.049) and MF-CAF (P = 0.048). EMG activity was not different between the conditions. CONCLUSIONS: Caffeine ingestion increased approximately 14 % endurance performance after the induction of mental fatigue. This effect was accompanied by a tendency to improvement in mood state (i.e., vigor). Therefore, caffeine ingestion can promote a beneficial effect on endurance performance in mentally fatigued individuals. PMID- 27695981 TI - Arthroscopic treatment of symptomatic discoid meniscus in children. AB - PURPOSE: To study discoid meniscus in children who underwent arthroscopic surgery at our center. SUBJECTS AND METHODS: Thirty-four patients (39 knees) younger than 15 years with discoid lateral meniscus (mean age, 12.9 years; 13 males, 21 females) who underwent arthroscopic surgeries since 2007 were studied. The surgical procedure consisted of, in principle, saucerization with additional suture repair in the case of meniscal instability at the peripheral rim of the residual meniscus. The mechanisms of symptom onset, symptoms, complications and postoperative outcome in these cases were examined. In addition, Lysholm scores were obtained before surgery and at the last postoperative follow-up in all patients. RESULTS: Symptom onset was associated with sports in 18 knees, fall in 3 knees, and no definitive trigger in the remaining knees. The presenting symptoms were pain in 32 knees, catching in 11 knees, and locking in 6 knees. According to Watanabe classification, 26 knees were complete type and 13 knees were incomplete type. The modes of tear included horizontal tear in 10 knees and longitudinal tear in 10 knees, while no definitive tear was present on the knee joint surface. The surgical procedures included saucerization only in 22 knees, partial meniscectomy in 10 knees, and saucerization with suture repair in 5 knees. The mean Lysholm score was 63.9 before surgery, and improved significantly to 92.3 at the last follow-up. Only two knees developed osteochondritis dissecans after surgery. Two knees required reoperation; one knee underwent subtotal meniscectomy and one knee had partial meniscectomy with suturing. CONCLUSION: Although the short-term outcome after saucerization with or without suture repair for discoid meniscus is favorable, degenerative change or change of lower limb alignment may occur in the long term. Further long-term study is required. PMID- 27695982 TI - Harbin: a quantitation PCR analysis tool. AB - OBJECTIVES: To enable analysis and comparisons of different relative quantitation experiments, a web-browser application called Harbin was created that uses a quantile-based scoring system for the comparison of samples at different time points and between experiments. RESULTS: Harbin uses the standard curve method for relative quantitation to calculate concentration ratios (CRs). To evaluate if different datasets can be combined the Harbin quantile bootstrap test is proposed. This test is more sensitive in detecting distributional differences between data sets than the Kolmogorov-Smirnov test. The utility of the test is demonstrated in a comparison of three grapevine leafroll associated virus 3 (GLRaV-3) RT-qPCR data sets. CONCLUSIONS: The quantile-based scoring system of CRs will enable the monitoring of virus titre or gene expression over different time points and be useful in other genomic applications where the combining of data sets are required. PMID- 27695983 TI - Development and validation of the modular Feed-code method for qualitative and quantitative determination of feed botanical composition. AB - The analysis of feed composition in terms of ingredients is addressed by Regulation (EC) 767/2009 and is important for detecting economic fraud and for monitoring feed safety. Within the framework of the EU project Feed-code, we developed and internally validated a modular assay, relying on intron polymorphism, for the complete qualitative analysis of the botanical composition of feed and the quantitative determination of six target plant species. Main performance parameters of each module, such as applicability, repeatability, specificity, and limit of detection, were evaluated. The whole assay was applied to a set of feed-like samples and results were in agreement with the expected composition. Application to a large set of compound feed and individual raw materials revealed the occurrence of botanical impurities. When compared with microscopic analysis, the proposed method gave more reliable results. We conclude that the Feed-code prototype, readily upgradable to include more plant species, is worthy of consideration for a full validation through a collaborative trial. Graphical Abstract The modular Feed-code method for the authentication of feed botanical composition. PMID- 27695984 TI - Introduction to polymer-based solid-contact ion-selective electrodes-basic concepts, practical considerations, and current research topics. AB - This review aims at providing an introductory overview for researchers new to the field of ion-selective electrodes. Both state of the art technology and novel developments towards solid-contact reference (sc-RE) and solid-contact ion selective electrodes (sc-ISE) are discussed. This technology has potentially widespread and important applications provided certain performance criteria can be met. We present basic concepts, operation principles, and theoretical considerations with regard to their function. Analytical performance and suitability of sc-RE and sc-ISE for a given application depend on critical parameters, which are discussed in this review. Comprehensive evaluation of sensor performance along this set of parameters is considered indispensable to allow for a well-founded comparison of different technologies. Methods and materials employed in the construction of sc-RE and sc-ISE, in particular the solid contact and the polymer membrane composite, are presented and discussed in detail. Operation principles beyond potentiometry are mentioned, which would further extend the field of ISE application. Finally, we conclude by directing the reader to important areas for further scientific research and development work considered particularly critical and promising for advancing this field in sensor R&D. Graphical Abstract ?. PMID- 27695985 TI - Limitations of turbidity process probes and formazine as their calibration standard. AB - Turbidity measurements are frequently implemented for the monitoring of heterogeneous chemical, physical, or biotechnological processes. However, for quantitative measurements, turbidity probes need calibration, as is requested and regulated by the ISO 7027:1999. Accordingly, a formazine suspension has to be produced. Despite this regulatory demand, no scientific publication on the stability and reproducibility of this polymerization process is available. In addition, no characterization of the optical properties of this calibration material with other optical methods had been achieved so far. Thus, in this contribution, process conditions such as temperature and concentration have been systematically investigated by turbidity probe measurements and Photon Density Wave (PDW) spectroscopy, revealing an influence on the temporal formazine formation onset. In contrast, different reaction temperatures do not lead to different scattering properties for the final formazine suspensions, but give an access to the activation energy for this condensation reaction. Based on PDW spectroscopy data, the synthesis of formazine is reproducible. However, very strong influences of the ambient conditions on the measurements of the turbidity probe have been observed, limiting its applicability. The restrictions of the turbidity probe with respect to scatterer concentration are examined on the basis of formazine and polystyrene suspensions. Compared to PDW spectroscopy data, signal saturation is observed at already low reduced scattering coefficients. PMID- 27695986 TI - Structural modifications of cellulose samples after dissolution into various solvent systems. AB - This work deals with the modifications resulting from the dissolution of four commercial cellulosic samples, with different crystallinity rates and degrees of polymerization (DPs), in four solvent systems, known and used to dissolve cellulose. The dissolution conditions were optimized for the 16 various systems and followed by turbidity measurements. After regeneration, the samples were analyzed by thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), and X-ray diffractometry (XRD) to study their modification. Viscosimetry measurements were used to evaluate the potential decrease of the DP after dissolution. The observed structural modifications established that, for low DP, all the solvent systems were efficient in dissolving the cellulose without altering the DP, except BMIM [Cl], which provoked a decrease of up to 40 % and a decrease of around 20 % of the degradation temperature (onset temperature, T o). For high molecular weight (MW) celluloses, DMSO/TBAF was the only system to allow a complete dissolution without any molar mass loss and degradation temperature modification. PMID- 27695987 TI - Variation in estimated glomerular filtration rate at dialysis initiation in children. AB - BACKGROUND: Data guiding the timing of dialysis initiation in children are limited. We sought to determine current practice and secular trends in Canada with respect to the timing of dialysis initiation in children based on estimated glomerular filtration rate (eGFR). METHODS: This observational study included incident chronic dialysis patients aged <=21 years identified from the Canadian Organ Replacement Register who started dialysis in Canada between January 2001 and December 2010 at any of the nine participating Canadian centers (n = 583). Youth were categorized utilizing CKiD Schwartz eGFR into >=10.5 (higher) or <10.5 ml/min/1.73 m2 (lower) eGFR groups. Differences at dialysis initiation by facility and region were examined, and secular trends were determined. RESULTS: Median eGFR at dialysis initiation was 8.1 (interquartile range 5.4-11.0) ml/min/1.73 m2. Overall, 29 % of the patients started dialysis with an eGFR of >=10.5 ml/min/1.73 m2. The proportion of children starting with higher eGFR increased from 27.3 % in 2001 to 35.4 % in 2010 (p = 0.04) and differed by treatment facility (12-70 %; p = 0.0001). Factors associated with higher eGFR at dialysis initiation in the adjusted regression model were female sex [odds ratio (OR) 1.48; 95 % confidence interval (CI) 1.02-2.14], genetic cause of end-stage kidney disease (OR 2.77; 95 % CI 1.37-5.58) and living >=50 km from treatment facility (OR 1.47; 95 % CI 1.01-2.14). CONCLUSIONS: One-third of the children were found to have initiated dialysis with an eGFR >=10.5 ml/min/1.73 m2, however significant practice variation exists with respect to timing of dialysis initiation by treatment facility. More data is required to evaluate the clinical implications of this practice variation. PMID- 27695988 TI - Prognosis in patients with atrial fibrillation and a presumed "temporary cause" in a community-based cohort study. AB - BACKGROUND: Atrial fibrillation (AF) may be related to acute and temporary causes, whether cardiovascular or non-cardiovascular. It remains unclear whether the risk of ischemic stroke is different in this setting, and whether antithrombotic management should be different in these patients. The objective of the study was to describe and compare the risk of stroke in AF patients with and with no such temporary precipitating cause. METHODS: Among 8962 patients with AF seen between 2000 and 2010, we focused our analysis on 4587 patients with non permanent AF, of whom 740 (16 %) had at least one possible temporary cause of AF. RESULTS: During a mean follow-up of 944 days (median 451, interquartile range 8 1624), the adjusted rates of stroke/TE were non-significantly different between patients with a temporary cause of AF and other AF patients (HR = 1.08, 95 % CI 0.82-1.41, p = 0.59 after adjustment on age, gender, CHA2DS2VASc score, OAC use and antiplatelet therapy use). Cardiovascular mortality was higher in patients with a temporary cause when compared to other AF patients (adjusted HR = 1.42, 95 % CI 1.08-1.86, p = 0.01). In patients with a temporary cause of AF, prescription of oral anticoagulation was independently associated with a better prognosis for cardiovascular death/stroke/thromboembolism (HR = 0.44, 95 % CI 0.29-0.67, p = 0.0001). CONCLUSION: AF patients with presumed temporary cause of AF had a similar risk of stroke/thromboembolism and a worse prognosis for cardiovascular mortality than other AF patients. Use of oral anticoagulation was associated with a better prognosis in these patients. PMID- 27695989 TI - Low level exercise echocardiography helps diagnose early stage heart failure with preserved ejection fraction: a study of echocardiography versus catheterization. AB - BACKGROUND: Increased left ventricular end-diastolic pressure (LVEDP) with exercise is an early sign of heart failure with preserved left ventricular ejection fraction (LVEF). The abnormal exercise increase in LVEDP is nonlinear, with most change occurring at low-level exercise. Data on non-invasive approach of this condition are scarce. Our objective was assessing E/e' to estimate low level exercise LVEDP using a direct invasive measurement as the reference method. METHODS AND RESULTS: Sixty patients with LVEF >50 % prospectively underwent both exercise cardiac catheterization and echocardiography. E/e' was measured at rest and during low-level exercise. Abnormal LVEDP was defined as >16 mmHg. Patients with a history of coronary artery disease and/or abnormal LV morphology were classified as having apparent cardiac disease (CD). Thirty-four (57 %) patients had elevated LVEDP only during exercise. Most of the change in LVEDP occurred since the first exercise level (25 W). There was a correlation between LVEDP and septal E/e' at rest and during exercise. Lateral E/e' and E/average e' ratio had worse correlations with LVEDP. In the whole population, exercise septal E/e' at 25 W had the best accuracy for abnormal exercise LVEDP, area under curve (AUC) = 0.79. However, while low-level exercise septal E/e' had a high accuracy in CD patients (n = 26, AUC = 0.96), E/e' was not linked to LVEDP in patients without CD (n = 34). CONCLUSION: Low-level exercise septal E/e' is valuable for predicting abnormal exercise LVEDP in patients with preserved LVEF and apparent CD. However, this new diagnosis approach appears not reliable in patients with normal LV morphology and without coronary artery disease. CLINICAL TRIAL REGISTRATION: https://clinicaltrials.gov . Unique identifier: NCT01714752. PMID- 27695990 TI - Functional and genetic predisposition to rhinovirus lower respiratory tract infections in prematurely born infants. AB - : Term born infants are predisposed to human rhinovirus (HRV) lower respiratory tract infections (LRTI) by reduced neonatal lung function and genetic susceptibility. Our aim was to investigate whether prematurely born infants were similarly predisposed to HRV LRTIs or any other viral LRTIs. Infants born less than 36 weeks of gestational age were recruited. Prior to neonatal/maternity unit discharge, lung function (functional residual capacity by helium gas dilution and multiple breath washout, lung clearance index and compliance (Crs), and resistance (Rrs) of the respiratory system) was assessed and DNA samples assessed for eight single nucleotide polymorphisms (SNPs) in seven genes: ADAM33, IL10, MMP16 NFkappaB1A,SFTPC, VDR, and NOS2A. Infants were prospectively followed until 1 year corrected age. Nasopharyngeal aspirates (NPAs) were sent whenever an infant developed a LRTI and tested for 13 viruses. One hundred and thirty-nine infants were included in the analysis. Infants who developed HRV LRTIs had reduced Crs (1.6 versus 1.2 mL/cmH2O/kg, p = 0.044) at 36 weeks postmenstrual age. A SNP in the gene coding for the vitamin D receptor was associated with the development of HRV LRTIs and any viral LRTIs (p = 0.02). CONCLUSION: Prematurely born infants may have both a functional and genetic predisposition to HRV LRTIs. What is Known: * Term born infants are predisposed to rhinovirus lower respiratory tract (HRV LRTIs) infection by reduced neonatal lung function. * Term born infants requiring hospitalisation due to HRV bronchiolitis were more likely to have single nucleotide polymorphism (SNP) in the IL-10 gene. What is New: * Prematurely born infants who developed a HRV LRTI had lower C rs before maternity unit discharge. * A SNP in the gene coding for the vitamin D receptor was associated with the development of HRV LRTIs and overall respiratory viral LRTIs in prematurely born infants. PMID- 27695991 TI - The functional variants of endothelial nitric oxide synthase gene associated with rheumatoid arthritis in Turkish adults. AB - This study aimed to investigate whether functional variants of endothelial nitric oxide synthase (eNOS) gene play any role in rheumatoid arthritis (RA) ethiopathogenesis and treatment in the Turkish population. Because, eNOS variants are responsible for alteration of the NO level in plasma, by reducing/increasing the endothelial NO synthesis. In the study, two eNOS gene variants (G894T and intron 4 VNTR A/B) were examined at extracted DNAs from 65 peripheral blood cell of RA patients. For the control, blood samples obtained from 70 healthy persons were studied. Genotyping of molecular variants was performed by PCR-RFLP and/or PCR technique. The data obtained was compared in itself and response to therapy. We found that "TT genotypic frequency" for the G894T variant was significantly associated with RA with an overall risk of 8.3-fold (p 0.029). No association was identified between intron 4 VNTR A/B variant and RA. At the 6 months, the mean visual analog scale (VAS), health assessment questionnaire (HAQ), and disease activity score for 28 joints (DAS 28) improvement was not significant among groups. Improvement in DAS was significantly better in anti-TNF treatment than disease-modifying antirheumatic drugs (DMARD) treatment treated subgroup. We report for the first time that variants in the eNOS "TT" genotype might be contributed to the increased risk of RA in the Turkish population. These results imply that functional variants of eNOS gene might have an effect on RA patients and response to anti-TNF treatment. In addition, the results suggest that eNOS variants might be associated and affect host susceptibility and/or response to treatment in Turkish RA patients. PMID- 27695992 TI - Analysis of the blood supply to the post-fracture edentulous mandible: study by colour Doppler sonography. AB - PURPOSE: This study assessed the arterial blood supply to the mandible of edentulous patients treated for mandibular fractures using colour Doppler ultrasound. METHODS: The blood supply of edentulous patients surgically treated for mandibular fractures (group A) and edentulous fracture-free individuals (group B) was assessed. Only the fractured sides were evaluated in the first group (N = 17), whereas each side was evaluated in the second group (N = 20). The arterial flow of six sites was assessed. The systolic-peak maximum velocity (SPV), final diastolic velocity (FDV), resistive index (RI), pulsatility index (PI), acceleration and flow direction of each artery were obtained. Additionally, the presence of local vascular obstructive factors was evaluated. The differences between groups were analysed using the Kruskal-Wallis test, which was complemented by the Mann-Whitney test, for correlations between the degree of alveolar atrophy and the study factors (p < 0.050). RESULTS: There was a significant decrease in the flow of certain arteries, especially the submental (SPV, p = 0.007, PI, p = 0.022, and acceleration, p = 0.015), in the fracture group. The facial artery in both groups showed lower values related to local obstructive factors (SPV, p = 0.001, FDV, p = 0.040, and PI, p = 0.030). The submental artery flow was higher (SPV, p = 0.006, and FDV, p = 0.009) in non atrophic individuals. CONCLUSIONS: There was a decreased flow mainly in the submental artery, but there were no cases of major vascular injury in edentulous patients treated for mandibular fractures.

PMID- 27695993 TI - Sinorhodobacter hungdaonensis sp. nov. isolated from activated sludge collected from a municipal wastewater treatment plant. AB - A novel bacterium, strain L3T, was isolated from an activated sludge sample retrieved from a municipal wastewater treatment plant in Huangdao, China. On the basis of 16S rRNA gene sequence similarity studies, strain L3T was affiliated to the genus Sinorhodobacter, being most closely related to Sinorhodobacter ferrireducens (98.0 %). The 16S rRNA gene sequence similarity of strain L3T to other related species, Thioclava atlantica DLFJ1-1T (96.5 %), Rhodobacter capsulatus ATCC 11166T (96.3 %), Paenirhodobacter enshiensis DW2-9T (96.3 %) and Rhodobacter viridis JA737T (96.0 %) is less than 96.5 %. Chemotaxonomic characterization further supported classification of the strain to the genus Sinorhodobacter. The major polar lipid profile consists of diphosphatidyglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major fatty acids are C18:1 omega7c (66.3 %), C16:0 (12.9 %) and C18:0 (8.0 %). The major quinone is Q 10. The G+C content of the genomic DNA of strain L3T is 68.0 mol %. DNA-DNA relatedness value between L3T and the closely related type strain S. ferrireducens SgZ-3T was 35.2 %. Based on these results, a new species Sinorhodobacter huangdaonensis is proposed. The type strain is L3T (= CGMCC 1.12963T = KCTC 42823T). PMID- 27695995 TI - High-throughput pyrosequencing used for the discovery of a novel cellulase from a thermophilic cellulose-degrading microbial consortium. AB - OBJECTIVES: To analyze the microbial diversity and gene content of a thermophilic cellulose-degrading consortium from hot springs in Xiamen, China using 454 pyrosequencing for discovering cellulolytic enzyme resources. RESULTS: A thermophilic cellulose-degrading consortium, XM70 that was isolated from a hot spring, used sugarcane bagasse as sole carbon and energy source. DNA sequencing of the XM70 sample resulted in 349,978 reads with an average read length of 380 bases, accounting for 133,896,867 bases of sequence information. The characterization of sequencing reads and assembled contigs revealed that most microbes were derived from four phyla: Geobacillus (Firmicutes), Thermus, Bacillus, and Anoxybacillus. Twenty-eight homologous genes belonging to 15 glycoside hydrolase families were detected, including several cellulase genes. A novel hot spring metagenome-derived thermophilic cellulase was expressed and characterized. CONCLUSIONS: The application value of thermostable sugarcane bagasse-degrading enzymes is shown for production of cellulosic biofuel. The practical power of using a short-read-based metagenomic approach for harvesting novel microbial genes is also demonstrated.

AB - This paper addresses the existence of Hopf bifurcations in a directed acyclic network of neurons, each of them being modeled by a Hindmarsh-Rose (HR) neuronal model. The bifurcation parameter is the small parameter corresponding to the ratio of time scales between the fast and the slow dynamics. We first prove that, under certain hypotheses, the single uncoupled neuron can undergo a Hopf bifurcation. Hopf bifurcation occurrences in a directed acyclic network of HR neurons are then discussed. Numerical simulations are carried out to observe these bifurcations and to illustrate the theoretical results.

AB - Genetic assessment for inherited cardiovascular disease (CVD) is increasingly available, due in part to rapid innovations in genetic sequencing technologies. While genetic testing is aimed at reducing uncertainty, it also produces awareness of potential medical conditions and can leave patients feeling uncertain about their risk, especially if there are ambiguous results. This uncertainty can produce psychological distress for patients and their families undergoing the assessment process. Additionally, patients may experience psychological distress related to living with inherited CVD. In order to more effectively manage the psychosocial challenges related to genetic assessment for CVD, a multidisciplinary model expanded to include psychologists and other allied health professionals is outlined. A case study is provided to illustrate how psychological distress can manifest in a patient living with inherited CVD, as well as proposed psychological management of this patient. Finally, a guide for genetic counselors is provided to aid in identifying and managing common psychological reactions to genetic assessment for CVD.

AB - Hox genes are the key regulators of axial regionalization of bilaterian animals. However, their main function is fulfilled differently in the development of animals from different evolutionary branches. Early patterning of the developing embryos by Hox gene expression in the representatives of protostomes (arthropods, mollusks) starts in the ectodermal cells. On the contrary, the instructive role of the mesoderm in the axial patterning was demonstrated for vertebrates. This makes it difficult to understand if during the axial regionalization of ancestral bilaterians Hox genes first expressed in the developing mesoderm or the ectoderm. To resolve this question, it is necessary to expand the number of models for investigation of the early axial patterning. Here, we show that three Hox genes of the polychaete Alitta virens (formerly Nereis virens, Annelida, Lophotrochozoa)-Hox2, Hox4, and Lox5-are expressed in the mesodermal anlagen of the three future larval chaetigerous segments in spatially colinear manner before the initiation of Hox expression in the larval ectoderm. This is the first evidence of sequential Hox gene expression in the mesoderm of protostomes to date.

AB - Congenital H-type fistula is a rare congenital rectourogenital connection with an external anal opening in a normal or ectopic position. A systematic review was done to study the anatomical types of congenital H-type fistula, embryology, clinical presentation, relative gender distribution, associated anomalies, investigative modalities, and recent advances in treatment of these lesions. A PubMed search included H-type anorectal malformation; H-type anorectal malformations; H-type anorectal; and H-type congenital anorectal that gave 9;43;76;26 abstracts, respectively. Relevant studies and cited articles were studied omitting duplicate search. The reported incidence is 0.1-16 % of all anorectal malformation. The H-type anorectal malformation is 2.5-6 times more common in females and usually associated with a normal anus. In males, the anomaly is usually a variant with an ectopic anus or a perineal fistula. Anatomical types include anovestibular; rectovestibular; rectovaginal fistula in females and rectourethral (bulbar, prostatic, bladder neck) and rectovesical fistula in males. Variants identified include H-type fistula with perineal fistula, perineal groove, H-type sinus, H-type canal, and acquired H-type fistula. This review compiles the available literature over last six decades. Various surgical corrective procedures have been described. The high recurrence decreases with a learning curve and experience. PMID- 27696000 TI - Modified PATIO repair for urethrocutaneous fistula post-hypospadias repair: operative technique and outcomes. AB - BACKGROUND: To describe a modification of PATIO repair for urethrocutaneous fistula repair and evaluate its outcome. METHODS: We studied 15 boys who underwent modified PATIO repair from Jan 2010 to Sept 2015. Parameters studied included age, type of hypospadias, age at first urethroplasty, hypospadias repair technique, number of urethroplasties required, location of fistula, time gap between urethroplasty and fistula repair, method of fistula repair, and outcome of fistula repair. RESULTS: Mean age of the studied patients was 67.6 months (38 139). Type of hypospadias was Coronal = 3, subcoronal = 8, mid-penile = 2, prominal penile = 1, and penoscrotal = 1. Ten patients had single urethroplasty, while two patients had two urethroplasties, details not available for three patients. Average age at urethroplasty was 43.4 months (18-110). 12 patients had Snodgrass repair, Mathieu = 1 patient, tubularised plate repair = 1 patient, and unknown = 1 patient. Location of fistula was coronal in nine patients and subcoronal in six patients. Average operative time was 47.2 min (30-68). Follow up is available for 12 patients out of which 2 patients had recurrent fistula, one of which was successfully treated by the redo modified PATIO method. CONCLUSION: Modified PATIO method is technically easy method for urethrocutaneous fistula repair, with less operating time and good postoperative outcomes. PMID- 27696001 TI - Perioperative stroke after carotid endarterectomy: etiology and implications. AB - BACKGROUND: Carotid endarterectomy (CEA) is the procedure of choice for reducing the risk of stroke in both symptomatic and asymptomatic carotid artery stenoses. Stroke is associated with significant morbidity and mortality peri-operatively (2 3 %). Our primary aim is to evaluate the etiology of these strokes after CEA and their impact on morbidity by comparing the length of stay in the hospital. METHODS: A total of 584 patients with documented neurological status evaluations who underwent CEAs were included in the study. Neurophysiological monitoring data was obtained during CEA for carotid stenosis included eight-channel electroencephalography (EEG) and upper extremity somatosensory evoked potentials (SSEPs). RESULTS: Twenty-one (3.595 %) patients had strokes in the perioperative period and they were more likely to have left-sided surgery (p = 0.008), intraoperative monitoring (IOM) changes (p < 0.001), an intraoperative shunt placed (p = 0.0002) or a hospital stay longer than 5 days (p = 0.0042). Unilateral anterior circulation ischemic stroke were the most common in our series. In a logistic regression model, left-sided surgery was shown to be 4.78 times more likely to be associated with perioperative stroke (1.50-15.27; p = 0.008) while intraoperative shunts were 11.85 times more likely to have strokes (3.97-35.34; p < 0.0001). Patients with stenosis greater than 70 % were 6.67 times less likely to have a stroke (0.04-0.59; p = 0.007). CONCLUSIONS: Ischemic anterior circulation strokes are the most common type of post-operative neurological changes in patients undergoing CEA. Intraoperative shunt placement was a strong predictor of perioperative strokes. Since shunts are only placed following intraoperative monitoring changes, SSEPs and EEG can therefore function as a biomarker of cerebral hypo-perfusion. PMID- 27696003 TI - Temporal effects of hunting on foraging behavior of an apex predator: Do bears forego foraging when risk is high? AB - Avoiding predators most often entails a food cost. For the Scandinavian brown bear (Ursus arctos), the hunting season coincides with the period of hyperphagia. Hunting mortality risk is not uniformly distributed throughout the day, but peaks in the early morning hours. As bears must increase mass for winter survival, they should be sensitive to temporal allocation of antipredator responses to periods of highest risk. We expected bears to reduce foraging activity at the expense of food intake in the morning hours when risk was high, but not in the afternoon, when risk was low. We used fine-scale GPS-derived activity patterns during the 2 weeks before and after the onset of the annual bear hunting season. At locations of probable foraging, we assessed abundance and sugar content, of bilberry (Vaccinium myrtillus), the most important autumn food resource for bears in this area. Bears decreased their foraging activity in the morning hours of the hunting season. Likewise, they foraged less efficiently and on poorer quality berries in the morning. Neither of our foraging measures were affected by hunting in the afternoon foraging bout, indicating that bears did not allocate antipredator behavior to times of comparably lower risk. Bears effectively responded to variation in risk on the scale of hours. This entailed a measurable foraging cost. The additive effect of reduced foraging activity, reduced forage intake, and lower quality food may result in poorer body condition upon den entry and may ultimately reduce reproductive success.

AB - Neurons in the posterior parietal cortex of macaques show spatial tuning during several phases of an instructed delay reaching task, but their reference frames have been studied mostly during fixed periods without addressing how they evolve across task phases. In parietal area V6A, we reported recently that during the late delay and hand movement periods, most neurons represent target location either in body-centered frame of reference, or in mixed body/hand-centered coordinates, with no evidence of hand-centered representations. Here, we characterized the spatial representations of V6A neurons in earlier task epochs, i.e., immediately after target fixation and in the subsequent main part of the delay and examined whether the reference frames of individual neurons are stable across the task. We report no evidence of hand-centered coding also in the earlier phases of the task. Shortly, after target fixation and throughout the main part of the delay period, V6A neurons used either body-centered or mixed body/hand-centered reference frames. Most of the cells showed consistent reference frames across epochs. Interestingly, a population trend of shifting from mixed body/hand-centered frames to 'pure' body-centered coordinates was found as the task progressed. These findings suggest that, similar to other parietal areas, in V6A, the reference frames show a limited degree of temporal evolution. The stronger presence of mixed coding at the early task stages could reflect the early involvement of V6A in eye-hand coordination, whereas the increase in spatiotopic representations towards movement execution could be related to its role in online movement control.

AB - Despite empirical evidence on the numerous consequences associated with high migration stress and mental health problems during pregnancy, a psychosocial stress assessment is rarely done, leaving it largely unaddressed. This case illustration sheds light on the common multiple risk factors related to migration stress that have to be taken into consideration when addressing perinatal mental health, and highlights the importance of obstetric appointments as a unique opportunity to assess psychosocial stress and mobilize interdisciplinary interventions. PMID- 27696002 TI - Modelling zinc changes at the hippocampal mossy fiber synaptic cleft. AB - Zinc, a transition metal existing in very high concentrations in the hippocampal mossy fibers from CA3 area, is assumed to be co-released with glutamate and to have a neuromodulatory role at the corresponding synapses. The synaptic action of zinc is determined both by the spatiotemporal characteristics of the zinc release process and by the kinetics of zinc binding to sites located in the cleft area, as well as by their concentrations. This work addresses total, free and complexed zinc concentration changes, in an individual synaptic cleft, following single, short and long periods of evoked zinc release. The results estimate the magnitude and time course of the concentrations of zinc complexes, assuming that the dynamics of the release processes are similar to those of glutamate. It is also considered that, for the cleft zinc concentrations used in the model (<= 1 MUM), there is no postsynaptic zinc entry. For this reason, all released zinc ends up being reuptaken in a process that is several orders of magnitude slower than that of release and has thus a much smaller amplitude. The time derivative of the total zinc concentration in the cleft is represented by the difference between two alpha functions, corresponding to the released and uptaken components. These include specific parameters that were chosen assuming zinc and glutamate co release, with similar time courses. The peak amplitudes of free zinc in the cleft were selected based on previously reported experimental cleft zinc concentration changes evoked by single and multiple stimulation protocols. The results suggest that following a low amount of zinc release, similar to that associated with one or a few stimuli, zinc clearance is mainly mediated by zinc binding to the high affinity sites on the NMDA receptors and to the low-affinity sites on the highly abundant GLAST glutamate transporters. In the case of higher zinc release brought about by a larger group of stimuli, most zinc binding occurs essentially to the GLAST transporters, having the corresponding zinc complex a maximum concentration that is more than one order of magnitude larger than that for the high and low affinity NMDA sites. The other zinc complexes considered in the model, namely those formed with sites on the AMPA receptors, calcium and KATP channels and with ATP molecules, have much smaller contributions to the synaptic zinc clearance.

PMID- 27696009 TI - Does drug price-regulation affect healthcare expenditures? AB - BACKGROUND: Increasing health costs in developed countries are a major concern for decision makers. A variety of cost containment tools are used to control this trend, including maximum price regulation and reimbursement methods for health technologies. Information regarding expenditure-related outcomes of these tools is not available. OBJECTIVE: To evaluate the association between different cost regulating mechanisms and national health expenditures in selected countries. METHODS: Price-regulating and reimbursement mechanisms for prescription drugs among OECD countries were reviewed. National health expenditure indices for 2008 2012 were extracted from OECD statistical sources. Possible associations between characteristics of different systems for regulation of drug prices and reimbursement and health expenditures were examined. RESULTS: In most countries, reimbursement mechanisms are part of publicly financed plans. Maximum price regulation is composed of reference-pricing, either of the same drug in other countries, or of therapeutic alternatives within the country, as well as value based pricing (VBP). No association was found between price regulation or reimbursement mechanisms and healthcare costs. However, VBP may present a more effective mechanism, leading to reduced costs in the long term. CONCLUSIONS: Maximum price and reimbursement mechanism regulations were not found to be associated with cost containment of national health expenditures. VBP may have the potential to do so over the long term. PMID- 27696010 TI - Novel Bioactive Co(II), Cu(II), Ni(II) and Zn(II) Complexes with Schiff Base Ligand Derived from Histidine and 1,3-Indandione: Synthesis, Structural Elucidation, Biological Investigation and Docking Analysis. AB - Novel bioactive complexes of Co(II), Cu(II), Ni(II) and Zn(II) metal ions with Schiff base ligand derived from histidine and 1,3-indandione were synthesized and thoroughly characterized by various analytical and spectral techniques. The biological investigations were carried out to examine the efficiency of the binding interaction of all the complexes with calf thymus DNA (CT-DNA). The binding properties were studied and evaluated quantitatively by Kb and Ksq values using UV-visible, fluorescence spectroscopy and voltammetric techniques. The experimental results revealed that the mode of binding of all the complexes with CT-DNA is via intercalation. It is further verified by viscosity measurements and thermal denaturation experiments. From the results of the cleavage study with pUC19 DNA it is inferred that all the complexes possess excellent cleaving ability. The present investigation proved that the binding interaction of all the complexes are significantly strong and the order of binding strength of the complexes is [Ni(L)2] (Kb = 3.11 * 106 M-1) > [Co(L)2] (Kb = 2.89 * 106 M-1) > [Cu(L)2] (Kb = 2.64 * 106 M-1) > [Zn(L)2] (Kb = 2.41 * 105 M-1). The complexes were also screened for antibacterial and anticandidal activity. The in vitro cytotoxicity of the ligand and complexes on the NIH/3 T3 mouse fibroblast cell lines were examined using CellTiter-Blue(r) (CTB) Cell viability assay, which unveiled that all the complexes exhibit more potent activities against NIH/3 T3 cells. Among all the complexes [Zn(L)2] complex showed the maximum efficiency. PMID- 27696011 TI - Comparative evaluation of two Rickettsia typhi-specific quantitative real-time PCRs for research and diagnostic purposes. AB - Rickettsioses are caused by intracellular bacteria of the family of Rickettsiaceae. Rickettsia (R.) typhi is the causative agent of endemic typhus. The disease occurs worldwide and is one of the most prevalent rickettsioses. Rickettsial diseases, however, are generally underdiagnosed which is mainly due to the lack of sensitive and specific methods. In addition, methods for quantitative detection of the bacteria for research purposes are rare. We established two qPCRs for the detection of R. typhi by amplification of the outer membrane protein B (ompB) and parvulin-type PPIase (prsA) genes. Both qPCRs are specific and exclusively recognize R. typhi but no other rickettsiae including the closest relative, R. prowazekii. The prsA-based qPCR revealed to be much more sensitive than the amplification of ompB and provided highly reproducible results in the detection of R. typhi in organs of infected mice. Furthermore, as a nested PCR the prsA qPCR was applicable for the detection of R. typhi in human blood samples. Collectively, the prsA-based qPCR represents a reliable method for the quantitative detection of R. typhi for research purposes and is a promising candidate for differential diagnosis. PMID- 27696012 TI - Intermittent vs. Continuous Anticoagulation theRapy in patiEnts with Atrial Fibrillation (iCARE-AF): a randomized pilot study. AB - PURPOSE: We hypothesized that intermittent anticoagulation based on daily rhythm monitoring using the novel oral anticoagulants (NOACs) is feasible and safe among patients with paroxysmal atrial fibrillation (AF). METHODS: Patients with paroxysmal AF and >=1 risk factors for stroke were randomized to either intermittent or continuous anticoagulation. Those in the intermittent group were instructed to transmit a daily ECG using an iPhone-based rhythm monitoring device. If AF was detected, patients received one of the NOACs for 48 h-1 week. Patients who failed to transmit an ECG for three consecutive days or more than 7 days total were crossed over to continuous anticoagulation. Patients in the continuous group received one of the NOACs. RESULTS: Fifty-eight patients were randomized to either intermittent (n = 29) or continuous anticoagulation (n = 29). Over a median follow-up of 20 months, 20 patients in the intermittent group failed to submit a daily ECG at least once (median three failed submissions). Four patients (14 %) crossed over to continuous anticoagulation due to failure to submit an ECG for three consecutive days. One stroke (continuous group) occurred during the study. Major bleeding occurred in two patients in the continuous and one patient in the intermittent group, after crossing over to continuous anticoagulation. In a prespecified per-protocol analysis, gastrointestinal bleeding was more frequent in the continuous group (16 vs. 0 %; p = 0.047). CONCLUSIONS: Intermittent anticoagulation based on daily rhythm monitoring is feasible and may decrease bleeding in low-risk patients with paroxysmal AF. A larger trial, adequately powered to detect clinical outcomes, is warranted. PMID- 27696013 TI - Ultrasound findings of diffuse metastasis of gastric signet-ring-cell carcinoma to the thyroid gland. AB - It has been shown that metastases to the thyroid from extrathyroidal malignancies occur as solitary or multiple nodules, or may involve the whole thyroid gland diffusely. However, diffuse metastasis of gastric cancer to the thyroid is extremely rare. Here, we report a case of a 74-year-old woman with diffuse infiltration of gastric adenocarcinoma (signet-ring-cell carcinoma/poorly differentiated adenocarcinoma) cells in the thyroid. The pathological diagnosis was made based on upper gastrointestinal endoscopy with biopsy and fine-needle aspiration cytology of the thyroid. An 18F-FDG PET/CT revealed multiple lesions with increased uptake, including the bilateral thyroid gland. On thyroid ultrasound examination, diffuse enlargement with internal heterogeneity and hypoechoic reticular lines was observed. On color Doppler imaging, a blood-flow signal was not detected in these hypoechoic lines. These findings were similar to those of diffuse metastases caused by other primary cancers, such as lung cancer, as reported earlier. Therefore, the presence of hypoechoic reticular lines without blood-flow signals is probably common to diffuse thyroid metastasis from any origin and an important diagnostic finding. This is the first report to show detailed ultrasound findings of diffuse gastric cancer metastasis to the thyroid gland using color Doppler.

However, heat shock responses, the associated components and the underlying functional mechanisms remain to be elucidated. Here, we characterize the expression pattern of HSFY, a member of the HSF family in the testis and epididymis. Its expression in testis and epididymis was initially identified by western blots. Immunofluorescence staining demonstrated that HSFY was confined to the cytoplasm of late spermatocytes and spermatids in adult testes, gonocytes in newborn testes and undifferentiated spermatogonia in 7 days post-parturition testes. In the epididymis, HSFY was predominantly expressed in principal cells. Furthermore, a single transient scrotal heat stress did not change HSFY protein expression in the testes or epididymis, either on the expressional level or in cellular localization. In summary, this study detected the expression pattern of HSFY in the testes and epididymis and demonstrated that its expression was not regulated by transient elevated temperature. PMID- 27696016 TI - Perspective: parameters in a self-consistent field theory of multicomponent wormlike-copolymer melts. AB - We review a formalism that can be used to calculate the microphase-separated crystallographic structures of multi-component wormlike polymer melts. The approach is based on a self-consistent field theory of wormlike polymers where the persistence length of each component is an important parameter. We emphasize on an analysis of the number of independent parameters required to specify a problem in general, for a system that includes Flory-Huggins and Maier-Saupe energies. Examples of recent applications are also briefly demonstrated: AB homopolymer interface, AB diblock copolymers, and rod-coil copolymers. PMID- 27696015 TI - A neurodegenerative perspective on mitochondrial optic neuropathies. AB - Mitochondrial optic neuropathies constitute an important cause of chronic visual morbidity and registrable blindness in both the paediatric and adult population. It is a genetically heterogeneous group of disorders caused by both mitochondrial DNA (mtDNA) mutations and a growing list of nuclear genetic defects that invariably affect a critical component of the mitochondrial machinery. The two classical paradigms are Leber hereditary optic neuropathy (LHON), which is a primary mtDNA disorder, and autosomal dominant optic atrophy (DOA) secondary to pathogenic mutations within the nuclear gene OPA1 that encodes for a mitochondrial inner membrane protein. The defining neuropathological feature is the preferential loss of retinal ganglion cells (RGCs) within the inner retina but, rather strikingly, the smaller calibre RGCs that constitute the papillomacular bundle are particularly vulnerable, whereas melanopsin-containing RGCs are relatively spared. Although the majority of patients with LHON and DOA will present with isolated optic nerve involvement, some individuals will also develop additional neurological complications pointing towards a greater vulnerability of the central nervous system (CNS) in susceptible mutation carriers. These so-called "plus" phenotypes are mechanistically important as they put the loss of RGCs within the broader perspective of neuronal loss and mitochondrial dysfunction, highlighting common pathways that could be modulated to halt progressive neurodegeneration in other related CNS disorders. The management of patients with mitochondrial optic neuropathies still remains largely supportive, but the development of effective disease-modifying treatments is now within tantalising reach helped by major advances in drug discovery and delivery, and targeted genetic manipulation. PMID- 27696018 TI - The Therapist's Role in Effective Marriage and Family Therapy Practice: The Case for Evidence Based Therapists. AB - In this paper we argue that the therapist is a crucial change variable in psychotherapy as a whole and in couple, marital, and family therapy specifically. Therapists who work with complex systems require more skills to negotiate demanding therapy contexts. Yet, little is known about what differentiates effective couple, marital, and family therapists from those who are less effective, what innate therapy skills they possess, how they learn, and how they operationalize their knowledge in the therapy room. We discuss the need to emphasize evidence based therapists (as opposed to therapies), and implications of the importance of the role therapists for training, practice, research priorities, and policy. PMID- 27696019 TI - Caretaking through Art: A Sibling Story. PMID- 27696017 TI - A randomized placebo-blind study of the effect of low power laser on pain caused by irreversible pulpitis. AB - This randomized placebo-blind study aimed to evaluate the effect of laser phototherapy (LPT) on pain caused by symptomatic irreversible pulpitis (SIP). Sixty patients diagnosed with SIP were randomly assigned to treatment groups (n = 15): G1 (control), G2 (laser placebo-sham irradiation), G3 (laser irradiation at 780 nm, 40 mW, 4 J/cm2), and G4 (laser irradiation at 780 nm, 40 mW, 40 J/cm2). Spontaneous pain was recorded using a VAS score before (T0), immediately after (T1), and 15 min after treatment (T2). Local anesthetics failure during emergency endodontic treatment was also assessed. There was no pain difference in T1 and T2 between the experimental laser groups (G3 and G4) and the placebo group (G2). The 4-J/cm2 (G3) irradiation resulted in significant increase in the local anesthetics failure in lower jar teeth. This effect could be suggested as consequence of the LPT improvement in local circulation and vasodilatation that would result in the increase of local anesthetic agent absorption. The application of 780-nm diode laser irradiation, at 4 and 40 J/cm2, showed no effect in reducing the pain in SIP in comparison to the placebo group. The fluence of 4 J/cm2 showed a negative effect in local anesthetics, resulting in significant increase of complimentary local anesthesia during emergency endodontic treatment. This work provides evidence of the consequence of LPT application on teeth with symptomatic irreversible pulpitis. LPT should be avoided in teeth with pain due to irreversible pulpitis. PMID- 27696020 TI - Morphological and ultrastructural characterization of the acidophilic and lipid producer strain Chlamydomonas acidophila LAFIC-004 (Chlorophyta) under different culture conditions. AB - Chlamydomonas acidophila LAFIC-004 is an acidophilic strain of green microalgae isolated from coal mining drainage. In the present work, this strain was cultivated in acidic medium (pH 3.6) under phototrophic, mixotrophic, and heterotrophic regimes to determine the best condition for growth and lipid production, simultaneously assessing possible morphological and ultrastructural alterations in the cells. For heterotrophic and mixotrophic treatments, two organic carbon sources were tested: 1 % glucose and 1 % sodium acetate. Lipid content and fatty acid profiles were only determined in phototrophic condition. The higher growth rates were achieved in phototrophic conditions, varying from 0.18 to 0.82 day-1. Glucose did not result in significant growth increase in either mixotrophic or heterotrophic conditions, and acetate proved to be toxic to the strain in both conditions. Oil content under phototrophic condition was 15.9 % at exponential growth phase and increased to 54.63 % at stationary phase. Based on cell morphology (flow cytometry and light microscopy) and ultrastructure (transmission electron microscopy), similar characteristics were observed between phototrophic and mixotrophic conditions with glucose evidencing many lipid bodies, starch granules, and intense fluorescence. Under the tested conditions, mixotrophic and heterotrophic modes did not result in increased neutral lipid fluorescence. It can be concluded that the strain is a promising lipid producer when grown until stationary phase in acidic medium and under a phototrophic regime, presenting a fatty acid profile suitable for biodiesel production. The ability to grow this strain in acidic mining residues suggests a potential for bioremediation with production of useful biomass. PMID- 27696021 TI - N,N-dimethyl hexadecylamine and related amines regulate root morphogenesis via jasmonic acid signaling in Arabidopsis thaliana. AB - Plant growth-promoting rhizobacteria are natural inhabitants of roots, colonize diverse monocot and dicot species, and affect several functional traits such as root architecture, adaptation to adverse environments, and protect plants from pathogens. N,N-dimethyl-hexadecylamine (C16-DMA) is a rhizobacterial amino lipid that modulates the postembryonic development of several plants, likely as part of volatile blends. In this work, we evaluated the bioactivity of C16-DMA and other related N,N-dimethyl-amines with varied length and found that inhibition of primary root growth was related to the length of the acyl chain. C16-DMA inhibited primary root growth affecting cell division and elongation, while promoting lateral root formation and root hair growth and density in Arabidopsis thaliana (Arabidopsis) wild-type (WT) seedlings. Interestingly, C16-DMA induced the expression of the jasmonic acid (JA)-responsive gene marker pLOX2:uidA, while JA-related mutants jar1, coi1-1, and myc2 affected on JA biosynthesis and perception, respectively, are compromised in C16-DMA responses. Comparison of auxin-regulated gene expression, root architectural changes in WT, and auxin related mutants aux1-7, tir1/afb2/afb3, and arf7-1/arf19-1 to C16-DMA shows that the C16-DMA effects occur independently of auxin signaling. Together, these results reveal a novel class of aminolipids modulating root organogenesis via crosstalk with the JA signaling pathway. PMID- 27696022 TI - Propofol Inhibits NLRP3 Inflammasome and Attenuates Blast-Induced Traumatic Brain Injury in Rats. AB - Increasing evidence has demonstrated that inflammatory response plays a crucial role in the pathogenesis of secondary injury following blast-induced traumatic brain injury (bTBI). Propofol, a lipid-soluble intravenous anesthetic, has been shown to possess therapeutic benefit during neuroinflammation on various brain injury models. Recent findings have proved that the NOD-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasome involved in the process of the inflammatory response following brain trauma, may probably be a promising target in the treatment of bTBI. Rats were randomly divided into six groups (n = 8): normal group; bTBI-12 and 24 h group; bTBI-12 h and bTBI-24 h group treated with propofol; and bTBI treated with control dimethyl sulfoxide (DMSO) group. The effect of propofol on the expression and activation of NLRP3 inflammasome and the degree of oxidative stress and inflammatory cascades, as well as the brain trauma biomarkers were evaluated in rats suffering from bTBI. The enhanced expressions and activation of NLRP3 inflammasome in the cerebral cortex of bTBI rats were substantially suppressed by the administration of propofol, which was paralleled with the decreased oxidative stress, cytokines production, and the amelioration of cerebral cortex damage. Our results have, for the first time, revealed that over-activation of NLRP3 inflammasome in the cerebral cortex may be involved in the process of neuroinflammation during the secondary injury of bTBI in rats. Propofol might relieve the inflammatory response and attenuate brain injury by inhibiting ROS and reluctant depressing NLRP3 inflammasome activation and pro inflammatory cytokines maturation.

AB - Riboflavin (vitamin B2) is an essential nutrient for humans and animals that must be obtained from the diet. To ensure an optimal supply, riboflavin is used on a large scale as additive in the food and feed industries. Here, we describe a historical overview of the industrial process of riboflavin production starting from its discovery and the need to produce the vitamin in bulk at prices that would allow for their use in human and animal nutrition. Riboflavin was produced industrially by chemical synthesis for many decades. At present, the development of economical and eco-efficient fermentation processes, which are mainly based on Bacillus subtilis and Ashbya gossypii strains, has replaced the synthetic process at industrial scale. A detailed account is given of the development of the riboflavin overproducer strains as well as future prospects for its improvement. PMID- 27696026 TI - ? PMID- 27696027 TI - ? PMID- 27696028 TI - ? AB - The prevalence of cerebral palsy (CP) has increased over the last 15 years in most countries. This is explained by an improved survival of very low birth weight prematures. In term infants birth asphyxia is of minor significance as a cause for CP. In only 10% of all CP cases following delivery at term, birth asphyxia must be discussed as a possible cause. In premature deliveries events during the perinatal period are of greater significance for the later development of a CP. Only severe forms of oxygen deficit, leading to tissue damage in the brain and other organs with clinical symptoms during the first days of life, are of significance for the long term prognosis. Even in the presence of severe birth asphyxia the causal relationship with a psychomotor handicap is not proven, since brain damage may have developed during pregnancy before the onset of labour and may be the cause of birth asphyxia. Brain damage and birth asphyxia may be the result of a common pathology of pregnancy. PMID- 27696029 TI - ? PMID- 27696030 TI - ? PMID- 27696031 TI - ? PMID- 27696033 TI - ? PMID- 27696032 TI - ?

PMID- 27696068 TI - Cardiac dysfunction in type II diabetes: a bittersweet, weighty problem, or both? AB - AIMS: Weight loss in obese patients leads to improved left ventricular (LV) function. It is unclear whether improving glycaemic control has additional benefits to weight loss alone in patients with type 2 diabetes, or if benefits of weight loss are mediated through improving glycaemic control. This case-control study examined the incremental impact of these approaches on LV function. METHODS: Three groups of age, gender, and baseline HbA1c-matched patients with type 2 diabetes and suboptimal glycaemic control were followed-up for 12 months. Group 1 patients did not improve HbA1c >= 1 % (10.9 mmol/mol) or lose weight. Group 2 improved HbA1c >= 1 % but did not lose weight. Group 3 improved HbA1c >= 1 % (10.9 mmol/mol) and lost weight. All patients underwent transthoracic echocardiogram at baseline and at follow-up. RESULTS: At baseline, three groups were comparable in all clinical and metabolic parameters except Group 3 had highest body mass index. The three groups had similar echocardiographic parameters except Group 3 had the worst LV systolic function [global longitudinal strain (GLS)]. At follow-up, LV ejection fraction and diastolic function improved with a reduction in filling pressures in Group 2 and more so in Group 3. LV filling pressures in Group 1 increased. There was a significant improvement in GLS in Group 2 and more so in Group 3. Despite GLS being the worst in Group 3 at baseline, this was comparable between Groups 2 and 3 at follow-up. CONCLUSIONS: In overweight patients with type 2 diabetes, weight loss and improved glycaemic control had additive beneficial effects on improving LV systolic and diastolic function.

PMID- 27696070 TI - MicroRNA-126 and micro-/macrovascular complications of type 1 diabetes in the EURODIAB Prospective Complications Study. AB - AIMS: Increasing evidence suggests a potential role of circulating miRNAs as clinical biomarkers, and loss of miRNA-126 has been proposed as a predictor of type 2 diabetes onset. However, a systematic analysis of circulating miRNAs in type 1 diabetic patients with micro-/macrovascular complications has not yet been performed. METHODS: A cross-sectional nested case-control study from the EURODIAB Prospective Complications Study of 455 type 1 diabetic patients was performed. Case subjects (n = 312) were defined as those with one or more complications of diabetes; control subjects (n = 143) were those with no evidence of any complication. A differential miRNA expression profiling was performed in pooled serum samples from cases and controls. Furthermore, miR-126 levels were quantified by qPCR in all individual samples and associations with diabetic complications investigated. RESULTS: Twenty-five miRNAs differed in pooled samples from cases and controls. miR-126 levels were significantly lower in case than in control subjects, even after adjustment for age and sex. In logistic regression analyses, miR-126 was negatively associated with all complications (OR = 0.85, 95 % CI 0.75-0.96) as well as with each micro-/macrovascular complication examined separately. This was likely dependent of diabetes as associations were no longer significant after adjustment for both hyperglycemia and diabetes duration. However, a significant 25 % risk reduction, independent of age, sex, A1C, and diabetes duration, was still observed for proliferative retinopathy (OR = 0.75, 95 % CI 0.59-0.95). CONCLUSIONS: In this large cohort of type 1 diabetic subjects, we found that miR-126 levels are associated with vascular complications of diabetes, particularly with proliferative retinopathy.

PMID- 27696072 TI - Sex ratio at birth is associated with type 1 diabetes characteristics. AB - AIMS: To assess the association between maternal diabetes characteristics and sex ratio at birth (SRB) in women with type 1 diabetes mellitus. METHODS: We performed a case-control study. The study subjects were infants born alive to women with type 1 diabetes and singleton pregnancies. Cases and controls were defined as male and female newborns, respectively. SRB was analysed according to diabetes-related characteristics adjusting in a logistic regression analysis for maternal characteristics known to affect SRB in the general population. RESULTS: The observed SRB (238 males/468 live births = 0.509) did not differ from the expected. In the logistic regression analysis, SRB was significantly associated with three diabetes characteristics: (1) diabetes duration, with odds ratios (ORs) for a live male newborn = 1.22 (95 % confidence interval (CI), 0.66-2.24 for <=5 years, OR 2.79 (95 % CI 1.36-5.74) for >20 years; (2) mean first trimester glycated haemoglobin, with OR 1.98 (95 % CI 1.09-3.62) for <=6.7 % (50 mmol/mol) and OR 2.61 (95 % CI 1.16-5.85) for >8.2 % (66 mmol/mol) and (3) mean first-trimester insulin dose, with OR 0.70 (95 % CI 0.36-1.38) for <=0.5 IU/kg/day and OR 0.18 (95 % CI 0.05-0.59) for >1.0 IU/kg/day. CONCLUSIONS: We conclude that SRB in this cohort is independently associated with three diabetes characteristics. These associations are to be confirmed. PMID- 27696073 TI - The influence of bottom boundary layer hydrodynamics on sediment focusing in a contaminated bay. AB - Understanding the dynamics and fate of particle bound contaminants is important for mitigating potential environmental, economic and health impacts linked to their presence. Vidy Bay, Lake Geneva (Switzerland), is contaminated due to the outfall and overflow from the wastewater treatment plant of the City of Lausanne. This study was designed to investigate the fate of particle-bound contaminants with the goal of providing a more complete picture of contaminant pathways within the bay and their potential spread to the main basin. This goal was achieved by investigating the sediment transport dynamics, using sediment traps and radionuclide tracers, and ascertaining how local bottom-boundary hydrodynamic conditions (temperature, turbidity, current velocity and direction) influence these dynamics. Results of the study indicated that sedimentation rates and lateral advections increased vertically with proximity to the lakebed and laterally with proximity to shore, indicating the presence of sediment focusing in the bay. Hydrodynamic measurements showed the persistent influence of a gyre within the bay, extending down to the lake bed, while just outside of the bay circulation was influenced by the seasonal patterns of the main basin. Calculated mean displacement distances in the bay indicated that suspended particles can travel ~3 km per month, which is 1.7 times the width of the Vidy Bay gyre. This results in a residence time of approximately 21 days for suspended particles, which is much greater than previously modelled results. The calculated mobility Shield parameter never exceeded the threshold shear stress needed for resuspension in deeper parts of the bay. In such, increased lateral advections to the bay are not likely due to local resuspension but rather external particle sources, such as main basin or shallow, littoral resuspensions. These external sources coupled with an increased residence time and decreased current velocity within the bay are the precipitating factors in sediment focusing. While the spread of contaminants from the bay may occur through the transport of fine suspended sediments in shallower zones of the bay (<60 m) by longshore littoral currents, results suggest that particle-bound contaminants are likely to remain within the bay.

PMID- 27696074 TI - Occurrence of pharmaceuticals in WWTP effluents and their impact in a karstic rural catchment of Eastern France. AB - The occurrence of pharmaceuticals in freshwater ecosystems provokes increasing concern due to their potential risk to non-target organisms and to human health. Pharmaceuticals are used in both human and veterinary medicine and are essentially released into the environment via wastewater treatment plants (WWTPs) and from livestock. In this study, 31 pharmaceuticals were analyzed in effluent and surface water upstream and downstream of two WWTPs in the Loue-Doubs rural karstic catchment in Eastern France. Diclofenac (965 and 2476 ng L-1), sulfamethoxazole (655 and 1380 ng L-1) and carbamazepine (566 and 1007 ng L-1) displayed the highest levels in the effluents of both WWTPs. Diclofenac levels were also high in surface water samples 300 and 166 ng L-1 in the River Doubs and the River Loue, respectively, followed by paracetamol (273 and 158 ng L-1) and sulfamethoxazole (126 and 73 ng L-1). In both rivers, the most critical compounds were found to be the antibiotic sulfamethoxazole (risk quotient (RQ) from 23.7 to 51.1) and ofloxacine (RQ from 1.1 to 18.9), which reached levels inducing toxic effects in aquatic organisms. This study showed that WWTP effluents are the major sources of the pharmaceuticals, but raw discharges from human residences, pastures and livestock manure represent significant sources of contamination of surface water and groundwater. The aim of this study was to assist scientists and authorities in understanding occurrence and sources of pharmaceuticals in order to improve water quality management in chalk streams. PMID- 27696076 TI - Characterization of miRNAs responsive to exogenous ethylene in grapevine berries at whole genome level. AB - MicroRNAs (miRNAs) are critical regulators of various biological and metabolic processes of plants. Numerous miRNAs and their functions have been identified and analyzed in many plants. However, till now, the involvement of miRNAs in the response of grapevine berries to ethylene has not been reported yet. Here, Solexa technology was employed to deeply sequence small RNA libraries constructed from grapevine berries treated with and without ethylene. A total of 124 known and 78 novel miRNAs were identified. Among these miRNAs, 162 miRNAs were clearly responsive to ethylene, with 55 downregulated, 59 upregulated, and 14 unchanged miRNAs detected only in the control. The other 35 miRNAs responsive to ethylene were induced by ethylene and detected only in the ethylene-treated grapevine materials. Expression analysis of 27 conserved and 26 novel miRNAs revealed that 13 conserved and 18 novel ones were regulated by ethylene during the whole development of grapevine berries. High-throughput sequencing and qRT-PCR assays revealed consistent results on the expression results of ethylene-responsive miRNAs. Moreover, 90 target genes for 34 novel miRNAs were predicted, most of which were involved in responses to various stresses, especially like exogenous ethylene treatment. The identified miRNAs may be mainly involved in grapevine berry development and response to various environmental conditions. PMID- 27696077 TI - Differences in sleep habits, study time, and academic performance between US-born and foreign-born college students. AB - PURPOSE: To inform the design of a sleep improvement program for college students, we assessed academic performance, sleep habits, study hours, and extracurricular time, hypothesizing that there would be differences between US born and foreign-born students. METHODS: Questionnaires queried participants on bedtimes, wake times, nap frequency, differences in weekday and weekend sleep habits, study hours, grade point average, time spent at paid employment, and other extracurricular activities. Comparisons were made using chi square tests for categorical data and t tests for continuous data between US-born and foreign born students. RESULTS: Of 120 participants (55 % women) with racial diversity (49 whites, 18 blacks, 26 Hispanics, 14 Asians, and 13 other), 49 (41 %) were foreign-born. Comparisons between US-born and foreign-born students showed no differences in average age or gender though US-born had more whites. There were no differences between US-born and foreign-born students for grade point averages, weekday bedtimes, wake times, or total sleep times. However, US-born students averaged 50 min less study time per day (p = 0.01), had almost 9 h less paid employment per week (14.5 vs 23.4 h per week, p = 0.001), and stayed up to socialize more frequently (63 vs 43 %, p = 0.03). Foreign-born students awakened an hour earlier and averaged 40 min less sleep per night on weekends. CONCLUSIONS: Cultural differences among college students have a profound effect on sleep habits, study hours, and extracurricular time. The design of a sleep improvement program targeting a population with diverse cultural backgrounds must factor in such behavioral variations in order to have relevance and impact. PMID- 27696078 TI - Quality of life (QOL) and symptom burden (SB) in patients with breast cancer. AB - PURPOSE: The purpose of this study was to determine the quality of life (QOL) and symptom burden (SB) among breast cancer patients. METHODS: Patients with DCIS, early stage, locally advanced, or metastatic breast cancer completed the Edmonton Symptom Assessment System (ESAS) and the Functional Assessment of Cancer Therapy for Breast Cancer (FACT-B). Patients were divided into subsequent cohorts based on their last day of treatment, age at enrollment, radiation, chemotherapy, and hormone therapy. RESULTS: A total of 1513 patients were enrolled. Metastatic patients had a lower QOL and greatest SB compared to all other patient groups. Patients <=50 years old with early stage or locally advanced breast cancer had a lower QOL and greater SB for fatigue, depression, and anxiety compared to all other age cohorts. Patients with early stage breast cancer who received chemotherapy had a lower QOL and greater SB. Patients taking selective estrogen receptor modulator (SERM) had greater SB for depression and lower QOL compared to those not on SERM. Patients 2-10 years post-treatment had a lower QOL compared to patients >=10 years post-treatment. CONCLUSION: Patients <=50 years old, 2-10 years post-treatment, treated with chemotherapy or SERM had increased SB and decreased QOL. Individualized interventions and programs can be developed to tailor to physical, educational, and psychosocial needs identified across the breast cancer continuum. PMID- 27696080 TI - Determining protein biomarkers for DLBCL using FFPE tissues from HIV negative and HIV positive patients. AB - DLBCL is the most common lymphoma subtype occurring in older populations as well as in younger HIV infected patients. The current treatment options for DLBCL are effective for most patients yet the relapse rate is high. While many biomarkers for DLBCL exist, they are not in clinical use due to low sensitivity and specificity. In addition, these biomarkers have not been studied in the HIV context. Therefore, the identification of new biomarkers for HIV negative and HIV positive DLBCL, may lead to a better understanding of the disease pathology and better therapeutic design. Protein biomarkers for DLBCL were determined using MALDI imaging mass spectrometry (IMS) and characterised using LC-MS. The expression of one of the biomarkers, heat shock protein (Hsp) 70, was confirmed on a separate cohort of samples using immunohistochemistry. The biomarkers identified in the study consisted of four protein clusters including glycolytic enzymes, ribosomal proteins, histones and collagen. These proteins could differentiate between control and tumour tissue, and the DLBCL immunohistochemical subtypes in both cohorts. The majority (41/52) of samples in the confirmation cohort were negative for Hsp70 expression. The HIV positive DLBCL cases had a higher percentage of cases expressing Hsp70 than their HIV negative counterparts. The non-GC subtype also frequently overexpressed Hsp70, confirming MALDI IMS data. The expression of Hsp70 did not correlate with survival in both the HIV negative and HIV positive cohort. This study identified potential biomarkers for HIV negative and HIV positive DLBCL from FFPE tissue sections. These may be used as diagnostic and prognostic markers complementary to current clinical management programmes for DLBCL. PMID- 27696081 TI - Tyrosine Hydroxylase Expression in Type II Cochlear Afferents in Mice. AB - Acoustic information propagates from the ear to the brain via spiral ganglion neurons that innervate hair cells in the cochlea. These afferents include unmyelinated type II fibers that constitute 5 % of the total, the majority being myelinated type I neurons. Lack of specific genetic markers of type II afferents in the cochlea has been a roadblock in studying their functional role. Unexpectedly, type II afferents were visualized by reporter proteins induced by tyrosine hydroxylase (TH)-driven Cre recombinase. The present study was designed to determine whether TH-driven Cre recombinase (TH-2A-CreER) provides a selective and reliable tool for identification and genetic manipulation of type II rather than type I cochlear afferents. The "TH-2A-CreER neurons" radiated from the spiral lamina, crossed the tunnel of Corti, turned towards the base of the cochlea, and traveled beneath the rows of outer hair cells. Neither the processes nor the somata of TH-2A-CreER neurons were labeled by antibodies that specifically labeled type I afferents and medial efferents. TH-2A-CreER-positive processes partially co-labeled with antibodies to peripherin, a known marker of type II afferents. Individual TH-2A-CreER neurons gave off short branches contacting 7-25 outer hair cells (OHCs). Only a fraction of TH-2A-CreER boutons were associated with CtBP2-immunopositive ribbons. These results show that TH-2A CreER provides a selective marker for type II versus type I afferents and can be used to describe the morphology and arborization pattern of type II cochlear afferents in the mouse cochlea. PMID- 27696082 TI - The association between China's Great famine and risk of breast cancer according to hormone receptor status: a hospital-based study. AB - PURPOSE: The Great Chinese Famine afflicted almost all Chinese people between 1959 and 1961. No study has explicitly assessed the association between an exposure to Chinese Famine and risk of overall breast cancer and tumor subtype. We evaluated the unique historical environmental influences of famine exposure on breast cancer subtypes. METHODS: 16,469 Chinese women who were diagnosed with invasive breast cancer in the Fudan University Shanghai Cancer Center (FUSCC) from 1999 to 2014 were analyzed. Four tumor subtypes were defined by both estrogen-receptor (ER) and progesterone-receptor (PR) status. Multinomial logistic regression models were used to estimate the odds ratios (ORs) of ER-PR-, ER+PR-, and ER-PR+ relative to ER+PR+ breast cancer for exposure to famine and age at the exposure. RESULTS: Compared with cases not exposed to the Famine, exposed cases were more likely to be diagnosed with ER-PR- (OR 1.60, 95 % CI 1.43 1.81), ER-PR+ (OR 4.85, 95 % CI 3.80-6.19), and ER+PR- (OR 1.99, 95 % CI 1.67 2.37) than ER+PR+ breast cancer after controlling for established breast cancer risk factors. Women exposed to Famine after first birth had a higher risk of EP PR- (OR 1.66, 95 % CI 1.28-2.15), ER-PR+ (OR 9.75, 95 % CI 5.85-16.25), and ER+PR (OR 2.35, 95 % CI 1.69-3.26) compared to those with ER+PR+ breast cancer. CONCLUSIONS: Women exposed to the Famine, particularly those exposed after first birth, were more likely to be diagnosed with ER-PR-, ER-PR+, and ER+PR- breast cancer. This retrospective analysis suggests that famine, malnutrition, or the associated lack of fruit and vegetable consumption in adulthood may be related to epidemiological heterogeneity within breast cancer subtypes. PMID- 27696083 TI - Impact of apoptotic circulating tumor cells (aCTC) in metastatic breast cancer. AB - PURPOSE: While intact circulating tumor cells (iCTC) have independent negative prognostic impact on patients with metastatic breast cancer (MBC), the prognostic relevance of apoptotic CTC (aCTC) has not been validated in larger patient cohorts. This study assessed aCTC and iCTC statuses at baseline (CTCBL) and CTC kinetics (CTCKIN) as changes from CTCBL to one completed treatment cycle for their utility in predicting response, progression-free survival (PFS), and overall survival (OS) in MBC. METHODS: Status of iCTC and aCTC was prospectively assessed in 442 patients using the CellSearchTM system. Different cutoffs were analyzed both for iCTC and aCTC (>=5, >=10, >=25 and >=50 CTC/7.5 ml). CTCKIN were characterized by >=25 % changes in CTC counts. RESULTS: Numbers of iCTC and aCTC at baseline correlated strongly (r = 0.7). For iCTCBL positive patients, additional detection of aCTCBL had a significant prognostic impact on OS (aCTCBL positive 10.3 vs. aCTCBL negative 16.4 months, p = 0.012). Worst prognosis for OS was observed in patients with >=50 iCTC/7.5 ml and simultaneously detected aCTC. Determination of aCTCKIN showed stronger discriminating power than iCTCKIN, with higher PFS and OS for the group with decreasing CTCs (PFS 7.7 vs. 6.1; OS 22.2 vs. 16.4). CONCLUSIONS: Intact and aCTC are predictive of outcome in MBC. Apoptotic CTC counts >= 5/7.5 ml in conjunction with iCTC at baseline have an independent unfavorable prognostic impact on OS. Decreasing aCTCKIN at >= 5/7.5 ml in serial enumeration is associated with favorable outcome. Therefore, separate enumeration of iCTC and aCTC is useful in tailoring systemic treatment. PMID- 27696084 TI - Safe and effective use of rivaroxaban for treatment of cancer-associated venous thromboembolic disease: a prospective cohort study. AB - Low-molecular weight heparin (LMWH) has been the standard of care for treatment of venous thromboembolism (VTE) in patients with cancer. Rivaroxaban was approved in 2012 for the treatment of pulmonary embolism (PE) and deep vein thrombosis (DVT), but no prior studies have been reported specifically evaluating the efficacy and safety of rivaroxaban for cancer-associated thrombosis (CAT). Under a Quality Assessment Initiative (QAI), we established a Clinical Pathway to guide rivaroxaban use for CAT and now report a validation analysis of our first 200 patients. A 200 patient cohort with CAT (PE or symptomatic, proximal DVT), whose full course of anticoagulation was with rivaroxaban, were accrued. In competing risk analysis, primary endpoints at 6 months included new or recurrent PE or symptomatic proximal lower extremity DVT, major bleeding, clinically-relevant non major bleeding leading to discontinuation of rivaroxaban, or death. In competing risk analysis, the 6 months cumulative incidence of new or recurrent VTE was 4.4 % (95 % CI = 1.4-7.4 %), major bleeding was 2.2 % (95 % CI = 0-4.2 %) and all cause mortality 17.6 % (95 % CI = 11.7-23.0 %). In this cohort of 200 patients with active cancer and CAT the rates of new or recurrent VTE and major bleeding were comparable to the cancer subgroup analysis from the EINSTEIN studies. The results of our Clinical Pathway provide guidance on Rivaroxaban use for treatment of CAT, and suggest that safety and efficacy is preserved, compared with past published experience with LMWH. PMID- 27696087 TI - Risk factors for suture requirement and early hypotony in 23-gauge vitrectomy for complex vitreoretinal diseases. AB - PURPOSE: To find out the rate of suture requirement and post-operative hypotony in a series of 23-gauge pars plana vitrectomy cases and analyze the factors affecting post-operative hypotony and leakage of sclerotomy leading to suture placement. METHODS: This is a single-center retrospective interventional case series. Eighty-four eyes underwent 23-gauge vitrectomy. Primary endpoint measures were rate of leakage of 23-gauge sclerotomies requiring suture placement at the end of surgery and rate of early post-operative hypotony. Secondary endpoint measures were risk factors for early hypotony and leakage requiring suture placement at the end of surgery. RESULTS: Suture placement in at least one sclerotomy because of sclerotomy leakage was required in 28.6 % (24 of 84) of eyes at the end of surgery. Early post-operative hypotony was seen in 14.3 % (12 of 84). Silicone oil endotamponade and single-step surgery were found as factors increasing the risk of sclerotomy leakage leading to suture placement. Suture placement was the only significant factor increasing the risk of early post operative hypotony. CONCLUSION: Sclerotomy sutures may be required in 23-gauge surgery, more frequently in cases of single-step sclerotomy and/or silicone oil endotamponade. Meticulous suturation of leaking sclerotomies may decrease the rate of post-operative hypotony. PMID- 27696086 TI - Adenosine A2A receptor regulates expression of vascular endothelial growth factor in feto-placental endothelium from normal and late-onset pre-eclamptic pregnancies. AB - We aim to investigate whether A2A/nitric oxide-mediated regulation of vascular endothelial growth factor (VEGF) expression is impaired in feto-placental endothelial cells from late-onset pre-eclampsia. Cultures of human umbilical vein endothelial cells (HUVECs) and human placental microvascular endothelial cells (hPMECs) from normal and pre-eclamptic pregnancies were used. Assays by using small interference RNA (siRNA) for A2A were performed, and transfected cells were used for estimation of messenger RNA (mRNA) levels of VEGF, as well as for cell proliferation and angiogenesis in vitro. CGS-21680 (A2A agonist, 24 h) increases HUVEC and hPMEC proliferation in a dose response manner. Furthermore, similar to CGS-21680, the nitric oxide donor, S-nitroso-N-acetyl-penicillamine oxide (SNAP), increased cell proliferation in a dose response manner (logEC50 10-9.2 M). In hPMEC, CGS-21680 increased VEGF protein levels in both normal (~1.5-fold) and pre eclamptic pregnancies (~1.2-fold), an effect blocked by the A2A antagonist, ZM 241385 (10-5 M) and the inhibitor of NO synthase, N omega-nitro-L-arginine methyl ester hydrochloride (L-NAME). Subsequently, SNAP partially recovered cell proliferation and in vitro angiogenesis capacity of cells from normal pregnancies exposed to siRNA for A2A. CGS-21680 also increased (~1.5-fold) the level of VEGF mRNA in HUVEC from normal pregnancies, but not in pre-eclampsia. Additionally, transfection with siRNA for A2A decrease (~30 %) the level of mRNA for VEGF in normal pregnancy compared to untransfected cells, an effect partially reversed by co-incubation with SNAP. The A2A-NO-VEGF pathway is present in endothelium from microcirculation and macrocirculation in both normal and pre-eclamptic pregnancies. However, NO signaling pathway seems to be impaired in HUVEC from pre eclampsia. PMID- 27696085 TI - Transcriptomic effects of adenosine 2A receptor deletion in healthy and endotoxemic murine myocardium. AB - Influences of adenosine 2A receptor (A2AR) activity on the cardiac transcriptome and genesis of endotoxemic myocarditis are unclear. We applied transcriptomic profiling (39 K Affymetrix arrays) to identify A2AR-sensitive molecules, revealed by receptor knockout (KO), in healthy and endotoxemic hearts. Baseline cardiac function was unaltered and only 37 A2AR-sensitive genes modified by A2AR KO (>=1.2-fold change, <5 % FDR); the five most induced are Mtr, Ppbp, Chac1, Ctsk and Cnpy2 and the five most repressed are Hp, Yipf4, Acta1, Cidec and Map3k2. Few canonical paths were impacted, with altered Gnb1, Prkar2b, Pde3b and Map3k2 (among others) implicating modified G protein/cAMP/PKA and cGMP/NOS signalling. Lipopolysaccharide (LPS; 20 mg/kg) challenge for 24 h modified >4100 transcripts in wild-type (WT) myocardium (>=1.5-fold change, FDR < 1 %); the most induced are Lcn2 (+590); Saa3 (+516); Serpina3n (+122); Cxcl9 (+101) and Cxcl1 (+89) and the most repressed are Car3 (-38); Adipoq (-17); Atgrl1/Aplnr (-14); H19 (-11) and Itga8 (-8). Canonical responses centred on inflammation, immunity, cell death and remodelling, with pronounced amplification of toll-like receptor (TLR) and underlying JAK-STAT, NFkappaB and MAPK pathways, and a 'cardio-depressant' profile encompassing suppressed beta-adrenergic, PKA and Ca2+ signalling, electromechanical and mitochondrial function (and major shifts in transcripts impacting function/injury including Lcn2, S100a8/S100a9, Icam1/Vcam and Nox2 induction, and Adipoq, Igf1 and Aplnr repression). Endotoxemic responses were selectively modified by A2AR KO, supporting inflammatory suppression via A2AR sensitive shifts in regulators of NFkappaB and JAK-STAT signalling (IkappaBzeta, IkappaBalpha, STAT1, CDKN1a and RRAS2) without impacting the cardio-depressant gene profile. Data indicate A2ARs exert minor effects in un-stressed myocardium and selectively suppress NFkappaB and JAK-STAT signalling and cardiac injury without influencing cardiac depression in endotoxemia. PMID- 27696088 TI - Differential evolution for protein folding optimization based on a three dimensional AB off-lattice model. AB - This paper presents a differential evolution algorithm that is adapted for the protein folding optimization on a three-dimensional AB off-lattice model. The proposed algorithm is based on a self-adaptive differential evolution that improves the algorithm efficiency and reduces the number of control parameters. A mutation strategy for the fast convergence is used inside the algorithm. A temporal locality is used in order to speed up the algorithm convergence additionally and to find amino-acid conformations with the lowest free energy values. Within this mechanism a new vector is calculated when the trial vector is better than the corresponding vector from the population. This new vector is likely better than the trial vector and this accelerates convergence speed. Because of the fast convergence the algorithm has some chance to be trapped into the local optima. To mitigate this problem the algorithm includes reinitialization. The proposed algorithm was tested on amino-acid sequences that are used frequently in literature. The obtained results show that the proposed algorithm is superior to the algorithms from the literature and the obtained amino-acid sequences have significantly lower free energy values.

PMID- 27696092 TI - Levels of selected trace elements in Scots pine (Pinus sylvestris L.), silver birch (Betula pendula L.), and Norway maple (Acer platanoides L.) in an urbanized environment. AB - The aim of the study was to determine the concentrations of selected trace elements in needles and bark of Scots pine (Pinus sylvestris L.), leaves and bark of silver birch (Betula pendula L.), and Norway maple (Acer platanoides L.), as well as in the soil in which the trees grew, depending on their localization and hence the distribution of local pollution sources. The content of trace elements in needles of Scots pine, leaves of silver birch, and Norway maple and in bark of these trees depended on the location, tree species, and analyzed organ. The content of Fe, Mn, and Zn in needles, leaves, and bark of the examined tree species was significantly higher than that of the other elements. The highest average content of Fe and Mn was detected in leaves of Norway maple whereas the highest average content of Zn was found in silver birch leaves. The impact of such locations as the center of Olsztyn or roadside along Road 51 on the content of individual elements tended to be more pronounced than the influence of the other locations. The influence of the sampling sites on the content of trace elements in tree bark was less regular than the analogous effect in needles and leaves. Moreover, the relevant dependences were slightly different for Scots pine than for the other two tree species. The concentrations of heavy metals determined in the soil samples did not exceed the threshold values set in the Regulation of the Minister for the Environment, although the soil along Road 51 and in the center of Olsztyn typically had the highest content of these elements. There were also significant correlations between the content of some trace elements in soil and their accumulation in needles, leaves, and bark of trees.

AB - The quantification studies of 17 carcinogenic and endocrine-disrupting polycyclic aromatic hydrocarbons (PAHs) in the Mithi River polluting the Mahim Creek near Mumbai were performed to understand their sources and probable ecological risk. The overall concentration level of SigmaPAHs was 157.96 +/- 18.99 MUg L-1, while that of carcinogenic PAHs (SigmaC-PAHs) was 81.31 +/- 9.75 MUg L-1, which corresponds to 51.5 % of the SigmaPAHs. The source analysis of PAH pollution was made on the basis of different PAH ratios. It was observed that the probable PAH contamination was due to pyrogenic inputs arising due to the combustion of grass, wood, and coal as well as due to the combustion of diesel and gasoline. Toxicity and biological risk assessment was made using toxic equivalent quantity (TEQ) for various C-PAHs. The results of our study showed that the mean BaP concentration in the Mithi River water (8.61 MUg L-1) was above the European Directive 2008/105/EC Environmental Quality Standards (EQS) value of 0.05 MUg L-1, while the levels of benzo(k)fluoranthene (BkF) + benzo(b)fluoranthene (BbF) (21.54 MUg L-1) and benzo(g,h,i)perylene (BghiP) + indeno(1,2,3,-c,d) pyrene (InP) (18.27 MUg L-1) were significantly higher than that set by the EQS (0.03 and 0.002 MUg L 1, respectively), showing that the ecological integrity of the river and the adjoining creek is possibly at risk.

PMID- 27696094 TI - A Macrophage Migration Inhibitory Factor Polymorphism Is Associated with Autoimmune Hepatitis Severity in US and Japanese Patients. AB - BACKGROUND: The pathogenesis of autoimmune hepatitis (AIH) is incompletely understood. Macrophage migration inhibitory factor (MIF) is an inflammatory cytokine implicated in the pathophysiology of multiple autoimmune diseases. We recently reported that MIF expression was increased in a US AIH cohort. MIF expression in non-Western AIH patients is unknown. A MIF-173 GC single nucleotide polymorphism in the MIF promoter (rs755622) is clinically associated with steroid resistance in several inflammatory disorders but has not been evaluated in AIH. AIM: To compare MIF polymorphisms and their relationship to clinical parameters in AIH patients from the USA and Japan. METHODS: DNA and matched sera from AIH patients and healthy controls from Japan (N = 52) were compared to the US group. Serum concentrations of MIF and its circulating receptor CD74 were measured by ELISA. MIF-173 GC (rs755622) and MIF-794 CATT5-8 (rs5844572) polymorphisms were analyzed by standard methods. MIF genotypes were correlated with serum ALT and steroid requirements. RESULTS: Serum MIF was increased in Japanese AIH patients versus local controls, in agreement with the US AIH patients. Within both AIH groups, ALT was higher in CC/GC versus GG patients. Further, the steroid requirement was higher in AIH patients with GC/CC genotypes from both groups. In the Japanese patient group, the GC/CC genotype also was associated with acute symptomatic presentation. CONCLUSIONS: The MIF-173 CC/GC genotypes may be associated with both higher ALT and maintenance steroid requirements in AIH patients from the USA and Japan. This polymorphism could be a marker of disease severity in AIH patients. PMID- 27696095 TI - Endoscopic Management of Large (>=2 cm) Non-pedunculated Colorectal Polyps: Impact of Polyp Morphology on Outcomes. AB - BACKGROUND AND AIMS: Referrals for endoscopic management of large non pedunculated (NP) colorectal polyps have increased as new techniques have emerged. The outcomes for referred large NP polyps based on the polyp morphology were investigated METHODS: A retrospective review of patients referred for large (>=20 mm) NP polyp management from January 2010 through June 2014 was completed. Polyp morphology was classified as either a NP polyp with depression (M1) or NP polyp with no depression (M0). Differences in treatment, histology, adverse events, outcomes at follow-up including residual disease, and need for surgical treatment were determined by morphology for all NP polyps >=20 mm in size. RESULTS: One-hundred and sixty-nine M1 and 136 M0 polyps >=20 mm were removed endoscopically during the review period. Mean size was 31.9 +/- 11.0 mm in M1, and 26.8 +/- 9.5 mm in M0 group (p < 0.0001). En bloc resection was possible in 18.3 % of M1 and 30.9 % of M0 lesions (p = 0.011) with endoscopic submucosal dissection used in 13 and 2.2 % of polyps, respectively (p < 0.0001). Residual polyp was found in 26.5 % (27/102) of M1 and 13.6 % (12/88) of M0 patients at surveillance colonoscopy (p = 0.029). On multivariate analysis, piecemeal resection and M1 morphology showed significant association with residual polyp (OR 4.23, 95 % CI 1.23-14.59, p = 0.022, and OR 2.15, 95 % CI 1.004-4.62, p = 0.049, respectively). CONCLUSION: Effective endoscopic management of large NP colorectal polyps, especially polyps without depression (M0), can be accomplished in the great majority of patients. Polyp morphology, particularly the presence or absence of depression, is a useful tool which influenced treatment, histology, and outcomes.

AB - BACKGROUND: Abdominal pain is a common complaint following endoscopic resection (ER). AIMS: To investigate the predictive factors for abdominal pain after ER. METHODS: Patients who were scheduled to undergo endoscopic mucosal resection or endoscopic submucosal dissection for the treatment of gastric adenoma or cancer were prospectively enrolled. Pain scores were checked every 6 h after ER and whenever patients complained of pain by using a 0-10 pain scale. If the pain score exceeded 5, 25 mg of intravenous (IV) pethidine was administered. RESULTS: Among 156 patients who underwent ER, 66 (42.3 %) received IV pethidine due to moderate/severe abdominal pain. Both the number of patients complaining of abdominal pain and the pain scores decreased with time following the procedure, with only a few patients complaining of mild abdominal pain 2 days after ER. Multivariate analysis showed that female sex [odds ratio (OR) 2.88; confidence interval (CI) 1.31-6.33], tumor location in the lower third of the stomach (OR 5.46; CI 2.31-12.92), and procedures time more than 60 min (OR 2.96; CI 1.26 6.98) were significant predictive factors for developing pain after ER. CONCLUSIONS: Female sex, tumor location in the lower third of the stomach, and longer procedure time were significantly associated with pain after ER. Close monitoring and active management of pain is recommended for patients who have these risk factors. With these efforts, the majority of patients could experience pain relief within 2 days after the procedure. PMID- 27696099 TI - Utilization of osteoporosis medication after a fragility fracture among elderly Medicare beneficiaries. AB - : Osteoporosis medications are recommended for elderly patients after a fragility fracture. However, we found substantial under-treatment in the post-fracture year, especially among patients who had not previously received such medications. Improved treatment of elderly patients experiencing fragility fractures is needed. INTRODUCTION: Osteoporosis medications are recommended for elderly patients after a fragility fracture, but under-treatment is common. We determined osteoporosis medication use after fragility fractures and examined associated factors. METHODS: Our cohort included elderly (age >=66 years) Medicare-enrolled patients who sustained fragility fractures January 1, 2008-December 31, 2011. Osteoporosis medication prescriptions were determined in the 12 months after the index fracture. Using multivariate logistic models, we examined the association between post-fracture osteoporosis medication use and predictors. RESULTS: Of 145,185 patients with fragility fractures (mean age 80.9 +/- 7.8 years; 91.2 % white; 81.3 % female), 29.9 % sustained hip, 31.8 % vertebral, and 38.4 % non-hip non-vertebral fractures. Overall, 30.4 % of the cohort received an osteoporosis medication in the 12-month post-fracture period. Of patients not receiving an osteoporosis medication in the pre-index period (n = 108,344), 14.9 % of all patients, 16.3 % of women, and 10.3 % of men received one in the post-fracture period. Corresponding values for patients receiving an osteoporosis medication in the pre-index period (n = 36,841) were 76.2, 76.5, and 72.2 %. Odds of post fracture osteoporosis medication use were 68 % higher for women than for men. Osteoporosis diagnosis (odds ratio, 1.55; P < 0.0001) and bone-mineral-density tests before an index fracture (odds ratio, 1.24; P < 0.001) were associated with post-fracture osteoporosis medication use. CONCLUSIONS: Less than one third of our cohort received an osteoporosis medication in the post-fracture year, when risk of a second fragility fracture is highest. In those not already previously treated with an osteoporosis medication, only about 1 in 7 patients received treatment. PMID- 27696100 TI - Midterm Clinical Outcomes of Antrum Resection Margin at Laparoscopic Sleeve Gastrectomy for Morbid Obesity. AB - BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is one of the most frequently performed procedures in obesity surgery. The benefits of minimally invasive surgery include rapid recovery. We evaluated the clinical outcomes of different resection margin lengths from the pylorus in LSG. METHODS: This retrospective study included 152 patients who underwent LSG from January 2011 to October 2014. The antrum was resected 2 cm from the pylorus in 84 patients (group A) and 6 cm from the pylorus in 68 patients (group B). The patients' demographics, staple line distance, complications, sex, age, body mass index loss, length of hospital stay, and comorbidities were retrospectively reviewed. RESULTS: The patients comprised 104 women (68.4 %) and 48 men (32.6 %) with a mean age of 41.2 years (range, 28-53 years). The percent total and excess weight loss were statistically significant in both groups at 6 and 12 months postoperatively. Weight loss was significantly greater in group A than that in B at 6 and 12 months, but the difference at 24 months was not statistically significant. The results of pH monitoring showed significantly lower scores in group A than those in B at 6 and 12 months, but no difference at 24 months. CONCLUSION: LSG is an effective procedure with good short-term outcomes. Both procedures described herein are equally effective with respect to the patient's return to daily activities. Increasing the distance from the resection line to the pylorus is associated with better weight loss but slightly increased symptoms of gastroesophageal reflux disease without a significant difference in complications. PMID- 27696101 TI - Non-musicians also have a piano in the head: evidence for spatial-musical associations from line bisection tracking. AB - The spatial representation of ordinal sequences (numbers, time, tones) seems to be a fundamental cognitive property. While an automatic association between horizontal space and pitch height (left-low pitch, right-high pitch) is constantly reported in musicians, the evidence for such an association in non musicians is mixed. In this study, 20 non-musicians performed a line bisection task while listening to irrelevant high- and low-pitched tones and white noise (control condition). While pitch height had no influence on the final bisection point, participants' movement trajectories showed systematic biases: When approaching the line and touching the line for the first time (initial bisection point), the mouse cursor was directed more rightward for high-pitched tones compared to low-pitched tones and noise. These results show that non-musicians also have a subtle but nevertheless automatic association between pitch height and the horizontal space. This suggests that spatial-musical associations do not necessarily depend on constant sensorimotor experiences (as it is the case for musicians) but rather reflect the seemingly inescapable tendency to represent ordinal information on a horizontal line. PMID- 27696102 TI - Clinician behaviors in telehealth care delivery: a systematic review. AB - Literature on telehealth care delivery often addresses clinical, cost, technological, system, and organizational impacts. Less is known about interpersonal behaviors such as communication patterns and therapeutic relationship-building, which may have workforce development considerations. The purpose of this study was to conduct a systematic literature review to identify interpersonal health care provider (HCP) behaviors and attributes related to provider-patient interaction during care in telehealth delivery. Electronic searches were conducted using five indexes/databases: CINAHL, ERIC, PsychInfo, ProQuest Dissertations, PubMed; with hand-searching of the immediate past 10 years of five journals. Search concepts included: communication, telehealth, education, and health care delivery. Of 5261 unique article abstracts initially identified, 338 full-text articles remained after exclusion criteria were applied and these were reviewed for eligibility. Finally, data were extracted from 45 articles. Through qualitative synthesis of the 45 articles, we noted that papers encompassed many disciplines and targeted care to people in many settings including: home care, primary and specialist care, mental health/counseling, and multi-site teams. Interpersonal behaviors were observed though not manipulated through study designs. Six themes were identified: HCP-based support for telehealth delivery; provider-patient interactions during the telehealth event; environmental attributes; and guidelines for education interventions or evaluation of HCP behaviors. Although unable to identify current best practices, important considerations for practice and education did emerge. These include: perceptions of the utility of telehealth; differences in communication patterns such as pace and type of discourse, reliance on visual cues by both provider and patient especially in communicating empathy and building rapport; and confidentiality and privacy in telehealth care delivery. PMID- 27696103 TI - Validity: one word with a plurality of meanings. AB - Validity is one of the most debated constructs in our field; debates abound about what is legitimate and what is not, and the word continues to be used in ways that are explicitly disavowed by current practice guidelines. The resultant tensions have not been well characterized, yet their existence suggests that different uses may maintain some value for the user that needs to be better understood. We conducted an empirical form of Discourse Analysis to document the multiple ways in which validity is described, understood, and used in the health professions education field. We created and analyzed an archive of texts identified from multiple sources, including formal databases such as PubMED, ERIC and PsycINFO as well as the authors' personal assessment libraries. An iterative analytic process was used to identify, discuss, and characterize emerging discourses about validity. Three discourses of validity were identified. Validity as a test characteristic is underpinned by the notion that validity is an intrinsic property of a tool and could, therefore, be seen as content and context independent. Validity as an argument-based evidentiary-chain emphasizes the importance of supporting the interpretation of assessment results with ongoing analysis such that validity does not belong to the tool/instrument itself. The emphasis is on process-based validation (emphasizing the journey instead of the goal). Validity as a social imperative foregrounds the consequences of assessment at the individual and societal levels, be they positive or negative. The existence of different discourses may explain-in part-results observed in recent systematic reviews that highlighted discrepancies and tensions between recommendations for practice and the validation practices that are actually adopted and reported. Some of these practices, despite contravening accepted validation 'guidelines', may nevertheless respond to different and somewhat unarticulated needs within health professional education.

PMID- 27696105 TI - Blastomere biopsy for PGD delays embryo compaction and blastulation: a time-lapse microscopic analysis. AB - PURPOSE: The purpose of the study was to explore the effect of blastomere biopsy for preimplantation genetic diagnosis (PGD) on the embryos' dynamics, further cleavage, development, and implantation. METHODS: The study group included 366 embryos from all PGD treatments (September 2012 to June 2014) cultured in the EmbryoScopeTM time-lapse monitoring system. The control group included all intracytoplasmic sperm injection (ICSI) embryos cultured in EmbryoScopeTM until day 5 during the same time period (385 embryos). Time points of key embryonic events were analyzed with an EmbryoViewerTM. RESULTS: Most (88 %) of the embryos were biopsied at >=8 cells. These results summarize the further dynamic development of the largest cohort of biopsied embryos and demonstrate that blastomere biopsy of cleavage-stage embryos significantly delayed compaction and blastulation compared to the control non-biopsied embryos. This delay in preimplanation developmental events also affected postimplantation development as observed when the dynamics of non-implanted embryos (known implantation data (KID) negative) were compared to those of implanted embryos (KID positive). CONCLUSION: Analysis of morphokinetic parameters enabled us to explore how blastomere biopsy interferes with the dynamic sequence of developmental events. Our results show that biopsy delays the compaction and the blastulation of the embryos, leading to a decrease in implantation. PMID- 27696106 TI - In vitro and in vivo antitumor effects of the VO-chrysin complex on a new three dimensional osteosarcoma spheroids model and a xenograft tumor in mice. AB - Osteosarcoma (OS) is the most common primary tumor of bone, occurring predominantly in the second decade of life. High-dose cytotoxic chemotherapy and surgical resection have improved prognosis, with long-term survival for patients with localized disease. Vanadium is an ultra-trace element that after being absorbed accumulates in bone. Besides, vanadium compounds have been studied during recent years to be considered as representative of a new class of non platinum antitumor agents. Moreover, flavonoids are a wide family of polyphenolic compounds that display many interesting biological effects. Since coordination of ligands to metals can improve the pharmacological properties, we report herein, for the first time, the in vitro and in vivo effects of an oxidovanadium(IV) complex with the flavonoid chrysin on the new 3D human osteosarcoma and xenograft osteosarcoma mice models. The pharmacological results show that VOchrys inhibited the cell viability affecting the shape and volume of the spheroids and VOchrys suppressed MG-63 tumor growth in the nude mice without inducing toxicity and side effects. As a whole, the results presented herein demonstrate that the antitumor action of the complex was very promissory on human osteosarcoma models, whereby suggesting that VOchrys is a potentially good candidate for future use in alternative antitumor treatments. PMID- 27696108 TI - Higher Serum Uric Acid May Contribute to Cerebral Infarction in Patients with Type 2 Diabetes Mellitus: a Meta-Analysis. AB - Higher levels of serum uric acid tend to increase the diabetes-related complications. We performed a meta-analysis to investigate whether the higher serum uric acid levels were associated with cerebral infarction in type 2 diabetes patients. We searched for relevant studies in the PubMed, Embase, China National Knowledge Infrastructure, China BioMedicine, and VIP database until August 2015. All observational studies comparing serum uric acid levels in type 2 diabetic patients with and without cerebral infarction were included. We calculated the ratio of means (RoM) of serum uric acid by mean cerebral infarction/mean diabetic control from the individual studies and then pooled RoM and its 95 % confidence intervals (CI). A total of 23 eligible studies were identified. Pooled estimates indicated that type 2 diabetes patients with cerebral infarction were associated with 29 % (RoM 1.29; 95 % CI 1.26-1.31) higher serum uric acid levels than those without cerebral infarction in a random effect model. Subgroup analyses based on gender indicated that RoM was 1.23 (95 % CI 1.09-1.38) for men and 1.12 (95 % CI 0.98-1.27) for women. This meta-analysis suggests that higher serum uric acid levels may contribute to cerebral infarction in patients with type 2 diabetes. PMID- 27696109 TI - Effects of horticulture therapy on nursing home older adults in southern Taiwan. AB - PURPOSE: This study aimed to test the effects of horticulture therapy on activities of daily living, happiness, meaning of life, and interpersonal intimacy of nursing home older adults in southern Taiwan. METHODS: A quasi experimental study was applied. Eighty-five older adults aged 65 or older who lived in nursing homes in southern Taiwan were recruited conveniently. All participants completed the study: experimental group (n = 41) and control group (n = 44). The experimental group received horticulture therapy for 1 h once a week for 8 weeks, while the control group continued their routine daily activities. The following questionnaires were administered before and after the intervention period: (1) Barthel Index (BI), (2) Chinese Happiness Inventory short version (CHI), (3) Meaning of Life Scale (MLS), and (4) Interpersonal Intimacy Scale (IIS). RESULTS: The BI, CHI, MLS, and IIS scores significantly improved in the experimental group (p < .05). After 8 weeks of horticulture therapy, the BI, CHI, and IIS scores of experimental group participants were significantly better than the scores of control group participants (p < .05); however, the MLS scores of two groups showed no significant differences (p = .738). CONCLUSIONS: Horticulture therapy improved activities of daily living, happiness, and interpersonal intimacy of older adults in nursing homes. We recommend that nursing homes recruit and train personnel to lead horticultural therapy and to incorporate the therapy as routine daily activities in the facilities. PMID- 27696107 TI - Expanding the genotype-phenotype spectrum in hereditary colorectal cancer by gene panel testing. AB - Hereditary syndromes causing colorectal cancer include both polyposis and non polyposis syndromes. Overlapping phenotypes between the syndromes have been recognized and this make targeted molecular testing for single genes less favorable, instead there is a gaining interest for multi-gene panel-based approaches detecting both SNVs, indels and CNVs in the same assay. We applied a panel including 19 CRC susceptibility genes to 91 individuals of six phenotypic subgroups. Targeted NGS-based sequencing of the whole gene regions including introns of the 19 genes was used. The individuals had a family history of CRC or had a phenotype consistent with a known CRC syndrome. The purpose of the study was to demonstrate the diagnostic difficulties linked to genotype-phenotype diversity and the benefits of using a gene panel. Pathogenicity classification was carried out on 46 detected variants. In total we detected sixteen pathogenic or likely pathogenic variants and 30 variants of unknown clinical significance. Four of the pathogenic or likely pathogenic variants were found in BMPR1A in patients with unexplained familial adenomatous polyposis or atypical adenomatous polyposis, which extends the genotype-phenotype spectrum for this gene. Nine patients had more than one variant remaining after the filtration, including three with truncating mutations in BMPR1A, PMS2 and AXIN2. CNVs were found in three patients, in upstream regions of SMAD4, MSH3 and CTNNB1, and one additional individual harbored a 24.2 kb duplication in CDH1 intron1. PMID- 27696110 TI - Change in physical function among women as they age: findings from the Australian Longitudinal Study on Women's Health. AB - PURPOSE: Decline in physical function is common in older age, with important consequences for health-related quality of life, health care utilisation, and mortality. This study aimed to identify patterns of change in physical functioning (PF) for women in later life. METHODS: PF was measured longitudinally using the ten-item subscale of the Medical Outcomes Study 36-item Short Form Health Survey, for 10 515 participants of the Australian Longitudinal Study on Women's Health, who completed at least two surveys between 1999 (aged 73-78 years) and 2011 (aged 85-90 years). Conditional and unconditional latent profile analysis was conducted separately for deceased and surviving subgroups of women to uncover latent patterns of change in PF scores over time. RESULTS: Four patterns of change were identified for women who were still alive in 2011 (N = 5928), and four similar classes for deceased women (N = 4587): (1) 'poor PF' representing women with low PF scores, (2) 'moderate PF', (3) 'high PF', and (4) 'very high PF', where scores remained very high. All patterns exhibited a decrease in PF over time. Factors which predict low PF included sedentary levels of exercise, obese and overweight BMI, difficulty managing on income, and lower education. CONCLUSIONS: The results provided evidence for a gradual decrease in PF for all women with age; however, there was no evidence for an increased rate of decline prior to death. PMID- 27696111 TI - Atrial-focused views improve the accuracy of two-dimensional echocardiographic measurements of the left and right atrial volumes: a contribution to the increase in normal values in the guidelines update. AB - Current guidelines recommend that the atria be measured in 2D echocardiographic (2DE) apical views using the method-of-disks (MOD) or area-length (AL) technique as an alternative, although no definitive data exists that these are interchangeable. However, standard apical views maximize the long-axis of the left ventricle, rather than the dimensions of the atria, resulting in atrial foreshortening. We hypothesized that the increase in normal values of atrial volumes in the recent guidelines update was driven by data obtained using either the AL technique or dedicated atrial-focused views, which maximize the longitudinal dimension of the atria and thus provide larger volumes than the MOD measurements in standard apical views. We prospectively studied 30 patients (Philips iE33) to compare 2DE measurements of left and right atrial volumes (LAV, RAV) using the MOD and AL techniques in standard and atrial-focused views, against 3D echocardiography (3DE) derived volumes (QLab) as a reference. Compared to standard views, atrial-focused views provided significantly larger MOD volumes for both atria, which were in better agreement with 3DE, as reflected by higher correlation coefficients (LAV: r = 0.95 vs. 0.89; RAV: r = 0.89 vs. 0.84), smaller biases (LAV: -1 ml vs. 7 ml; RAV: 3 ml vs. 7 ml) and tighter limits of agreement. This was also the case for the AL measurements, which were minimally larger than the MOD values (NS) for both atria. In conclusion, atrial-focused views are a more accurate alternative to standard apical views, which provides larger volumes. This finding can explain the increase in the normal values in the recent guidelines update, which was mostly driven by the use of atrial-focused views, rather than by the differences between MOD and AL techniques. This understanding is essential in order to correctly integrate the revised normal values into clinical practice. PMID- 27696113 TI - The gating of the CFTR channel. AB - Cystic fibrosis transmembrane conductance regulator (CFTR) is an anion channel expressed in the apical membrane of epithelia. Mutations in the CFTR gene are the cause of cystsic fibrosis. CFTR is the only ABC-protein that constitutes an ion channel pore forming subunit. CFTR gating is regulated in complex manner as phosphorylation is mandatory for channel activity and gating is directly regulated by binding of ATP to specific intracellular sites on the CFTR protein. This review covers our current understanding on the gating mechanism in CFTR and illustrates the relevance of alteration of these mechanisms in the onset of cystic fibrosis. PMID- 27696112 TI - Laminin: loss-of-function studies. AB - Laminin, one of the most widely expressed extracellular matrix proteins, exerts many important functions in multiple organs/systems and at various developmental stages. Although its critical roles in embryonic development have been demonstrated, laminin's functions at later stages remain largely unknown, mainly due to its intrinsic complexity and lack of research tools (most laminin mutants are embryonic lethal). With the advance of genetic and molecular techniques, many new laminin mutants have been generated recently. These new mutants usually have a longer lifespan and show previously unidentified phenotypes. Not only do these studies suggest novel functions of laminin, but also they provide invaluable animal models that allow investigation of laminin's functions at late stages. Here, I first briefly introduce the nomenclature, structure, and biochemistry of laminin in general. Next, all the loss-of-function mutants/models for each laminin chain are discussed and their phenotypes compared. I hope to provide a comprehensive review on laminin functions and its loss-of-function models, which could serve as a reference for future research in this understudied field. PMID- 27696114 TI - Pinocembrin Provides Mitochondrial Protection by the Activation of the Erk1/2 Nrf2 Signaling Pathway in SH-SY5Y Neuroblastoma Cells Exposed to Paraquat. AB - Pinocembrin (PB; 5,7-dihydroxyflavanone; C15H12O4) is a flavonoid found in propolis and exerts antioxidant, anti-inflammatory, and antimicrobial effects. Furthermore, PB has been studied as a neuroprotective agent. However, it remains to be understood whether and how PB would induce mitochondrial protection in mammalian cells. Therefore, we investigated here the mechanism involved in the protective effects elicited by PB in paraquat (PQ; 100 MUM)-treated SH-SY5Y neuroblastoma cells. PB (25 MUM) pretreatment (for 4 h) downregulated the levels of Bcl-2-associated X protein (Bax), blocked the release of cytochrome c to the cytosol, and inhibited the PQ-induced activation of caspase-9 and caspase-3. Besides, PB prevented mitochondrial dysfunction by suppressing the PQ-elicited inhibition of complexes I and V. Moreover, PB abrogated the loss of mitochondrial membrane potential (MMP) and the decline in ATP levels in the cells exposed to PQ. PB exerted antioxidant effects on mitochondria by decreasing the levels of redox impairment markers in mitochondrial membranes. Importantly, PB enhanced the levels of mitochondrial reduced glutathione (GSH). Upregulation of enzymes involved in the synthesis of GSH was seen in the cells exposed to PB. PB afforded mitochondrial protection by activating the extracellular signal-regulated kinase/nuclear factor erythroid 2-related factor 2 (Erk1/2-Nrf2) axis, since inhibition of Erk1/2 or silencing of Nrf2 abrogated these effects. Therefore, PB exerted mitochondrial and cellular protection by an Erk1/2-Nrf2-dependent mechanism. PMID- 27696115 TI - The Analgesic and Anxiolytic Effect of Souvenaid, a Novel Nutraceutical, Is Mediated by Alox15 Activity in the Prefrontal Cortex. AB - Pain and anxiety have a complex relationship and pain is known to share neurobiological pathways and neurotransmitters with anxiety. Top-down modulatory pathways of pain have been shown to originate from cortical and subcortical regions, including the dorsolateral prefrontal cortex. In this study, a novel docosahexaenoic acid (DHA)-containing nutraceutical, Souvenaid, was administered to mice with infraorbital nerve ligation-induced neuropathic pain and behavioral responses recorded. Infraorbital nerve ligation resulted in increased face wash strokes of the face upon von Frey hair stimulation, indicating increased nociception. Part of this response involves general pain sensitization that is dependent on the CNS, since increased nociception was also found in the paws during the hot plate test. Mice receiving oral gavage of Souvenaid, a nutraceutical containing DHA; choline; and other cell membrane components, showed significantly reduced pain sensitization. The mechanism of Souvenaid's activity involves supraspinal antinociception, originating in the prefrontal cortex, since inhibition of the DHA-metabolizing enzyme 15-lipoxygenase (Alox15) in the prefrontal cortex attenuated the antinociceptive effect of Souvenaid. Alox15 inhibition also modulated anxiety behavior associated with pain after infraorbital nerve ligation. The effects of Souvenaid components and Alox15 on reducing central sensitization of pain may be due to strengthening of a known supraspinal antinociceptive pathway from the prefrontal cortex to the periaqueductal gray. Together, results indicate the importance of the prefrontal cortex and DHA/Alox15 in central antinociceptive pathways and suggest that Souvenaid may be a novel therapeutic for neuropathic pain.

AB - Mitochondrial diseases collectively represent one of the most heterogeneous group of metabolic disorders. Symptoms can manifest at any age, presenting with isolated or multiple-organ involvement. Advances in next-generation sequencing strategies have greatly enhanced the diagnosis of patients with mitochondrial disease, particularly where a mitochondrial aetiology is strongly suspected yet OXPHOS activities in biopsied tissue samples appear normal. We used whole exome sequencing (WES) to identify the molecular basis of an early-onset mitochondrial syndrome-pathogenic biallelic variants in the HTRA2 gene, encoding a mitochondria localised serine protease-in five subjects from two unrelated families characterised by seizures, neutropenia, hypotonia and cardio-respiratory problems. A unifying feature in all affected children was 3-methylglutaconic aciduria (3-MGA-uria), a common biochemical marker observed in some patients with mitochondrial dysfunction. Although functional studies of HTRA2 subjects' fibroblasts and skeletal muscle homogenates showed severely decreased levels of mutant HTRA2 protein, the structural subunits and complexes of the mitochondrial respiratory chain appeared normal. We did detect a profound defect in OPA1 processing in HTRA2-deficient fibroblasts, suggesting a role for HTRA2 in the regulation of mitochondrial dynamics and OPA1 proteolysis. In addition, investigated subject fibroblasts were more susceptible to apoptotic insults. Our data support recent studies that described important functions for HTRA2 in programmed cell death and confirm that patients with genetically-unresolved 3-MGA uria should be screened by WES with pathogenic variants in the HTRA2 gene prioritised for further analysis. PMID- 27696116 TI - A Mitocentric View of Alzheimer's Disease. AB - Alzheimer's disease (AD) is a neurodegenerative disease with an increasing morbidity, mortality, and economic cost. Plaques formed by amyloid beta peptide (Abeta) and neurofibrillary tangles formed by microtubule-associated protein tau are two main characters of AD. Though previous studies have focused on Abeta and tau and got some progressions on their toxicity mechanisms, no significantly effective treatments targeting the Abeta and tau have been found. However, it is worth noting that mounting evidences showed that mitochondrial dysfunction is an early event during the process of AD pathologic changes. What is more, these studies also showed an obvious association between mitochondrial dysfunction and Abeta/tau toxicity. Furthermore, both genetic and environmental factors may increase the oxidative stress and the mitochondria are also the sensitive target of ROS, which may form a vicious feedback between mitochondrial dysfunction and oxidative stress, eventually resulting in deficient energy, synaptic failure, and cell death. This article reviews the previous related studies from different aspects and concludes the critical roles of mitochondrial dysfunction in AD, suggesting a different route to AD therapy, which may guide the research and treatment direction. PMID- 27696119 TI - Interactions in the Metabolism of Glutamate and the Branched-Chain Amino Acids and Ketoacids in the CNS. AB - Glutamatergic neurotransmission entails a tonic loss of glutamate from nerve endings into the synapse. Replacement of neuronal glutamate is essential in order to avoid depletion of the internal pool. In brain this occurs primarily via the glutamate-glutamine cycle, which invokes astrocytic synthesis of glutamine and hydrolysis of this amino acid via neuronal phosphate-dependent glutaminase. This cycle maintains constancy of internal pools, but it does not provide a mechanism for inevitable losses of glutamate N from brain. Import of glutamine or glutamate from blood does not occur to any appreciable extent. However, the branched-chain amino acids (BCAA) cross the blood-brain barrier swiftly. The brain possesses abundant branched-chain amino acid transaminase activity which replenishes brain glutamate and also generates branched-chain ketoacids. It seems probable that the branched-chain amino acids and ketoacids participate in a "glutamate-BCAA cycle" which involves shuttling of branched-chain amino acids and ketoacids between astrocytes and neurons. This mechanism not only supports the synthesis of glutamate, it also may constitute a mechanism by which high (and potentially toxic) concentrations of glutamate can be avoided by the re-amination of branched chain ketoacids. PMID- 27696121 TI - Pituitary abscess: clinical manifestations, diagnosis and treatment of 66 cases from a large pituitary center over 23 years. AB - PURPOSE: Pituitary abscess (PA) is rare and commonly described in case reports or small case series. This study aimed to better determine salient clinical manifestations related to the diagnosis and appropriate treatment of PA using by far the largest case series of this disease. METHODS: A total of 6361 consecutive patients underwent surgery for pituitary diseases in Peking Union Medical College Hospital between January 1991 and December 2013. Among this cohort, sixty-six patients were diagnosed with PA based on both intraoperative findings and postoperative histopathological evidence. RESULTS: The most common clinical presentation was anterior pituitary hypofunction (81.8 %), followed by common headache (69.7 %), diabetes insipidus (DI; 47.9 %), visual disturbances (45.5 %) and symptoms related to infection (43.9 %). Forty patients (66.7 %) showed typical rim enhancement after gadolinium injection on magnetic resonance imaging (MRI). Most patients (63 of 66, 95.5 %) underwent transsphenoidal surgery (TSS), and the remaining 3 patients (4.5 %) were treated with transcranial surgery (TC). After follow-up for 7.2 +/- 4.9 years, PA was diminished in most patients (81.8 %), as demonstrated by post-operative MRI, and eight patients underwent at least one additional operation due to recurrence. CONCLUSIONS: For patients with hypopituitarism and DI with rim enhancement on MRI, we should consider the possible diagnosis of PA. Proper use of antibiotics, complete drainage via surgery and hormone replacement for hypopituitarism are the key treatments for PA. PMID- 27696120 TI - Role of Estradiol in the Regulation of Prolactin Secretion During Late Pregnancy. AB - Estrogen action is necessary for evidencing the stimulatory action of mifepristone and naloxone on prolactin (PRL) secretion during late pregnancy. Our aim is to determine the mechanism mediating this facilitator action of estrogens. To investigate the hypothalamic mechanisms involved in estrogen actions in PRL secretion at the end of pregnancy, we measured the effect of pretreatment with the estrogen antagonist tamoxifen on the expression of tyrosine hydroxylase (TH), hormone receptors (ERalpha and beta, PRs, PRLR(long)), and MU- and kappa- opioid receptors (ORs) at mRNA (by semiquantitative RT-PCR) and protein (by western blot for TH, PRLR(long), ERalpha, PRs, MU- and ORs) levels in extracts of medial basal hypothalamus (MBH) and serum PRL, E2 and P4 levels (by RIA) in mifepristone- and naloxone-treated rats. Tamoxifen administration partially prevented PRL release induced by the combined treatment. TH expression diminished and ERalpha expression increased in mifepristone-treated rats at mRNA and protein levels and tamoxifen partially prevented these changes with no effect on PRs expression. Mifepristone increased PRLR(long) mRNA levels; this increase was blocked by tamoxifen. Combined tamoxifen and mifepristone treatment decreased MU- and k-ORs mRNA but not protein levels. In conclusion, E2 induces neuroadaptive mechanisms necessary to facilitate PRL release preceding delivery. Acting through ERalpha, E2 modulates hypothalamic dopaminergic neurons activity, regulating TH, MU- and kappa-ORs and PRLR(long) expression, and is necessary for evidencing the effects of P4 withdrawal. Its presence on days 14 and 15 of pregnancy is crucial to facilitate the opioid system modulation of PRL secretion at the end of pregnancy in the rat. PMID- 27696122 TI - PD-1/PD-L1 expression in chromophobe renal cell carcinoma: An immunological exception? AB - Immune checkpoint inhibitors targeting the inhibitory cross talk between tumor and immune cells have been approved for therapy in renal cell carcinoma (RCC). In contrast to clear cell RCC, little is known on PD-1/PD-L1 expression patterns in rarer RCC subtypes. The aim of this study was to evaluate the prevalence, distribution and prognostic impact of PD-1 and PD-L1 expression in chromophobe (ch)RCC. Patients who underwent renal surgery due to chRCC were retrospectively evaluated. Tumor specimen was analyzed for PD-1 and PD-L1 expression by immunohistochemistry. Expression data were correlated with clinic-pathological parameters including patient survival. Eighty-one chRCC patients were eligible for analysis, thereof 25 (30.9 %) and 11 (13.6 %) patients were positive for PD 1+ tumor-infiltrating mononuclear cells (TIMCs) and tumoral PD-L1+ expression, respectively. No significant associations were found for PD-1+ TIMC or tumoral PD L1+ expression and clinical attributes. In addition, no differences in 5- and 10 year overall survival for PD-1- TIMC compared to PD-1+ TIMC (90.5 and 72.2 vs. 100 and 75 %; p = 0.41) and for PD-L1- tumors compared to PD-L1+ tumors (91.9 and 76.4 vs. 100 and 50 %; p = 0.48) were observed. In conclusion, to our knowledge this is the first study to evaluate the prognostic impact of PD-1 and PD-L1 in chRCC. PD-L1 does seem to be expressed in a minority of all chRCC, likewise only a minority of chRCC was infiltrated by PD-1-positive inflammatory cells. Neither PD-1+ TIMC nor tumoral PD-L1+ expression was associated with parameters of aggressiveness or survival. PMID- 27696123 TI - Sexual Reproduction in Dermatophytes. AB - Sexual reproduction is a rich source of genetic variation and commonly observed among fungi. Basically two different modes of sexual reproduction are observed in fungi, namely heterothallism where two compatible mating types are required to undergo mating and homothallism in which the organism is self-fertile. The genomic region governing the process of sexual reproduction and sex determination is called the mating type (MAT) locus. In filamentous ascomycetes including dermatophytes, the MAT locus harbors two different transcription factor genes in two different mating types. This review focuses on sexual reproduction and the structure of the MAT locus in dermatophytes. The reproductive modes and the observed mating types are summarized for different phylogenetic clades of dermatophytes. In addition, the question of whether or not unisexual reproduction, an interesting form of homothallism, may be the sexual reproduction mode especially in anthropophilic dermatophytes is raised. PMID- 27696125 TI - Meniscal allograft subluxations are not associated with preoperative native meniscal subluxations. AB - PURPOSE: To determine the relationship between preoperative subluxation of the original menisci and postoperative graft subluxation after lateral meniscal allograft transplantation (MAT). METHODS: Forty patients who underwent isolated lateral MATs in meniscus-deficient knees with a low-grade chondral lesion (<=ICRS grade 2) were assessed. Lateral subluxation of the native meniscus before meniscectomy and those of remaining meniscal tissue before MAT were measured on mid-coronal MRI scans taken at each time point. Postoperative meniscal subluxation was assessed using MRI at 6 months postoperatively, when the full rehabilitation protocols were completed. Correlation analyses were conducted to determine the associations between each of two preoperative lateral displacements and the postoperative graft subluxation. RESULTS: The mean lateral subluxations before primary meniscectomy and before MAT were 0.3 +/- 1.0 mm and 0.2 +/- 0.8 mm, respectively. At 6 months postoperatively, it was 2.3 +/- 1.9 mm. There were no significant correlations between the preoperative subluxation at the two preoperative time points and the postoperative extrusion (Spearman rho 2-sided test: rho = - 0.058, (n.s.) for the native meniscus; Pearson r 2-sided test, r = 0.309, (n.s.) for the remaining meniscal rim). Between the postoperative nonextruded and extruded groups, there were no significant differences for the preoperative subluxations. CONCLUSIONS: There are no associations between preoperative lateral subluxation of the native menisci and postoperative subluxation of meniscal transplants in patients who undergo MAT on the lateral compartment with low-grade arthritic changes. The extrusion phenomenon may be a distinct feature of transplanted menisci rather than an individual characteristic of meniscal displacement. Surgeons need to keep in mind that graft extrusion in nonarthritic knees might occur during transplantation. LEVEL OF EVIDENCE: IV. PMID- 27696126 TI - Integration of behavioral health and primary care: current knowledge and future directions. AB - Integrated behavioral health in primary care has spread rapidly over the past three decades, although significant questions remain unanswered regarding best practices in clinical, financial and operational worlds. Two key models have emerged over time: care management and Primary Care Behavioral Health. Research to date has been promising; however, there is a significant need for more sophisticated multi-level scientific methodologies to fill in the gaps in current knowledge of integrated primary care. In this paper, we summarize current scientific knowledge about integrated primary care and critically evaluate the strengths and weaknesses of this knowledge base, focusing on clinical, financial and operational factors. Finally, we recommended priorities for future research, dissemination, real-world implementation, and health policy implications. PMID- 27696124 TI - Peripheral blood mononuclear cell secretome for tissue repair. AB - For almost two decades, cell-based therapies have been tested in modern regenerative medicine to either replace or regenerate human cells, tissues, or organs and restore normal function. Secreted paracrine factors are increasingly accepted to exert beneficial biological effects that promote tissue regeneration. These factors are called the cell secretome and include a variety of proteins, lipids, microRNAs, and extracellular vesicles, such as exosomes and microparticles. The stem cell secretome has most commonly been investigated in pre-clinical settings. However, a growing body of evidence indicates that other cell types, such as peripheral blood mononuclear cells (PBMCs), are capable of releasing significant amounts of biologically active paracrine factors that exert beneficial regenerative effects. The apoptotic PBMC secretome has been successfully used pre-clinically for the treatment of acute myocardial infarction, chronic heart failure, spinal cord injury, stroke, and wound healing. In this review we describe the benefits of choosing PBMCs instead of stem cells in regenerative medicine and characterize the factors released from apoptotic PBMCs. We also discuss pre-clinical studies with apoptotic cell-based therapies and regulatory issues that have to be considered when conducting clinical trials using cell secretome-based products. This should allow the reader to envision PBMC secretome-based therapies as alternatives to all other forms of cell-based therapies. PMID- 27696128 TI - Regression analysis of current status data in the presence of a cured subgroup and dependent censoring. AB - This paper discusses regression analysis of current status data, a type of failure time data where each study subject is observed only once, in the presence of dependent censoring. Furthermore, there may exist a cured subgroup, meaning that a proportion of study subjects are not susceptible to the failure event of interest. For the problem, we develop a sieve maximum likelihood estimation approach with the use of latent variables and Bernstein polynomials. For the determination of the proposed estimators, an EM algorithm is developed and the asymptotic properties of the estimators are established. Extensive simulation studies are conducted and indicate that the proposed method works well for practical situations. A motivating application from a tumorigenicity experiment is also provided. PMID- 27696127 TI - A dyadic multiple mediation model of patient and spouse stressors predicting patient dietary and exercise adherence via depression symptoms and diabetes self efficacy. AB - Using dyadic data from 117 married couples in which one partner was diagnosed with Type 2 diabetes, the purpose of this study was to determine whether a number of specific patient and spouse stressors (chronic life stress, diabetes-specific stress, and physical health stress in the form of the number of comorbidities) were associated with Type 2 diabetes patients' dietary and exercise adherence through two potentially modifiable patient and spouse factors-depression symptoms and diabetes self-efficacy. We found that patient and spouse stressors, particularly patient and spouse diabetes stress and the number of patient comorbidities, were related to patient dietary and exercise adherence through patient depression symptoms and both patient and spouse diabetes self-efficacy. These conclusions were strengthened by incorporating a number of relevant control variables in our models and by testing four alternative models which supported our proposed model. These results are important because they provide further evidence of the significant role spouses' play in managing diabetes and they provide diabetes educators and clinicians with specific targets for intervention programming. PMID- 27696129 TI - Microscopic histological characteristics of soft tissue sarcomas: analysis of tissue features and electrical resistance. AB - Tissue electrical conductivity is correlated with tissue characteristics. In this work, some soft tissue sarcomas (STS) excised from patients have been evaluated in terms of histological characteristics (cell size and density) and electrical resistance. The electrical resistance has been measured using the ex vivo study on soft tissue tumors electrical characteristics (ESTTE) protocol proposed by the authors in order to study electrical resistance of surgical samples excised by patients in a fixed measurement setup. The measurement setup includes a voltage pulse generator (700 V, 100 us long at 5 kHz, period 200 us) and an electrode with 7 needles, 20 mm-long, with the same distance arranged in a fixed hexagonal geometry. In the ESTTE protocol, the same voltage pulse sequence is applied to each different tumor mass and the corresponding resistance has been evaluated from voltage and current recorded by the equipment. For each tumor mass, a histological sample of the volume treated by means of voltage pulses has been taken for histological analysis. Each mass has been studied in order to identify the sarcoma type. For each histological sample, an image at 20* or 40* of magnification was acquired. In this work, the electrical resistance measured for each tumor has been correlated with tissue characteristics like the type, size and density of cells. This work presents a preliminary study to explore possible correlations between tissue characteristics and electrical resistance of STS. These results can be helpful to adjust the pulse voltage intensity in order to improve the electrochemotherapy efficacy on some histotype of STS. PMID- 27696130 TI - Uncertainty assessment of gamma-aminobutyric acid concentration of different brain regions in individual and group using residual bootstrap analysis. AB - The aim of this work is to quantify individual and regional differences in the relative concentration of gamma-aminobutyric acid (GABA) in human brain with in vivo magnetic resonance spectroscopy. Spectral editing Mescher-Garwood point resolved spectroscopy (MEGA-PRESS) sequence and GABA analysis toolkit (Gannet) were used to detect and quantify GABA in anterior cingulate cortex (ACC) and occipital cortex (OCC) of healthy volunteers. Residual bootstrap, a model-based statistical analysis technique, was applied to resample the fitting residuals of GABA from the Gaussian fitting model (referred to as GABA+ thereafter) in both individual and group data of ACC and OCC. The inter-subject coefficient of variation (CV) of GABA+ in OCC (20.66 %) and ACC (12.55 %) with residual bootstrap was lower than that of a standard Gaussian model analysis (21.58 % and 16.73 % for OCC and ACC, respectively). The intra-subject uncertainty and CV of OCC were lower than that of ACC in both analyses. The residual bootstrap analysis thus provides a more robust uncertainty estimation of individual and group GABA+ detection in different brain regions, which may be useful in our understanding of GABA biochemistry in brain and its use for the diagnosis of related neuropsychiatric diseases.

PMID- 27696133 TI - First Record of Larval Secretions of Cochliomyia macellaria (Fabricius, 1775) (Diptera: Calliphoridae) Inhibiting the Growth of Staphylococcus aureus and Pseudomonas aeruginosa. AB - Maggot debridement therapy (MDT) consists on the intentional and controlled application of sterilized larvae of the order Diptera on necrotic skin lesions with the purpose of cleaning necrotic tissue and removing pathogenic bacteria. During MDT, a marked antimicrobial activity has been reported in literature specially associated with antibacterial substances from Lucilia sericata (Meigen); however, regarding Cochliomyia macellaria (Fabricius), little is known. This study aimed to evaluate in vitro inhibition of bacterial growth of Pseudomonas aeruginosa and Staphylococcus aureus in contact with excretions and secretions (ES) from C. macellaria larvae. Larval ES were extracted in sterile distilled water and divided in three groups: ES, containing 400 MUL of autoclaved ES; ES+BAC, containing 400 MUL of autoclaved ES+0.5-MUL bacterial inoculum; and CONT-BAC, containing 400 MUL of sterile distilled water +0.5 MUL of bacterial inoculum. Aliquots of each experimental group were plated by spreading onto Petri dishes. Seedings were made at 0, 1, 2, 4, and 12 h after the extraction of ES. In ES+BAC groups, inhibition of S. aureus was verified between times 1 and 2 h and P. aeruginosa was inhibited between 0 and 4 h. There was no growth observed in any ES group. In the CONT-BAC groups, the number of colonies from time 4 h became countless for S. aureus and decreased for P. aeruginosa. As reported in the literature, we note here that ES have excellent bactericidal activity for both gram-positive and gram-negative bacteria, and this study shows for the first time the action of the bactericidal activity of exosecretions of C. macellaria against S. aureus and P. aeruginosa. PMID- 27696135 TI - Acrolein increases macrophage atherogenicity in association with gut microbiota remodeling in atherosclerotic mice: protective role for the polyphenol-rich pomegranate juice. AB - The unsaturated aldehyde acrolein is pro-atherogenic, and the polyphenol-rich pomegranate juice (PJ), known for its anti-oxidative/anti-atherogenic properties, inhibits macrophage foam cell formation, the hallmark feature of early atherosclerosis. This study aimed to investigate two unexplored areas of acrolein atherogenicity: macrophage lipid metabolism and the gut microbiota composition. The protective effects of PJ against acrolein atherogenicity were also evaluated. Atherosclerotic apolipoprotein E-deficient (apoE-/-) mice that were fed acrolein (3 mg/kg/day) for 1 month showed significant increases in serum and aortic cholesterol, triglycerides, and lipid peroxides. In peritoneal macrophages isolated from the mice and in J774A.1 cultured macrophages, acrolein exposure increased intracellular oxidative stress and stimulated cholesterol and triglyceride accumulation via enhanced rates of their biosynthesis and over expression of key regulators of cellular lipid biosynthesis: sterol regulatory element-binding proteins (SREBPs), 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMGCR), and diacylglycerol acyltransferase1 (DGAT1). Acrolein-fed mice demonstrated a major shift in the gut microbiota composition, including a significant phylum-level change in increased Firmicutes and decreased Bacteroidetes. At the family level, acrolein significantly increased the prevalence of Ruminococcaceae and Lachnospiraceae of which the Coprococcus genus was significantly and positively correlated with serum, aortic and macrophage lipid levels and peroxidation. The pro-atherogenic effects of acrolein on serum, aortas, macrophages, and the gut microbiota were substantially abolished by PJ. In conclusion, these findings provide novel mechanisms by which acrolein increases macrophage lipid accumulation and alters the gut microbiota composition in association with enhanced atherogenesis. Moreover, PJ was found as an effective strategy against acrolein atherogenicity. PMID- 27696136 TI - Contemplative Intervention Reduces Physical Interventions for Children in Residential Psychiatric Treatment. AB - This research explored the effectiveness of a manualized contemplative intervention among children receiving intensive residential psychiatric care. Ten children with severe psychiatric disabilities received 12 sessions (30-45 min) of "Mindful Life: Schools" (MLS) over the course of a month. Facility-reported data on the use of physical intervention (i.e., seclusions and restraints) were analyzed. Acceptability questionnaires and broad-band behavioral questionnaire data were also collected from children and their primary clinicians. Robust logistic regression analyses were conducted on person-period data for the 10 children to explore the timing of incidents resulting in the use of physical intervention. Incidents within each person-period were regressed on indicators of days of contemplative practice and days without contemplative practice. Results indicated that during the 24-h period following MLS class, relative to a comparison 24-h period, children had significantly reduced odds of receiving a physical intervention (OR = 0.3; 95 % CI 0.2, 0.5; p < 0.001). Behavioral questionnaires did not indicate significant contemplative intervention effects (ps >0.05), and MLS was found to be generally acceptable in this population and setting. These data indicate that contemplative practices acutely reduced the utilization of physical interventions. Clinicians seeking to implement preventative strategies to reduce the necessity of physical intervention in response to dangerous behavior should consider contemplative practices. Those wishing to empirically evaluate the effectiveness of contemplative practices should consider evaluating objective measures, such as utilization of physical intervention strategies, as oppose to subjective reports. PMID- 27696137 TI - Cross-Sectional Survey on the Dengue Knowledge, Attitudes and Preventive Practices Among Students and Staff of a Public University in Malaysia. AB - Behavioural impact programmes are especially effective for dengue control and prevention. Universities are key settings for health promotion, so understanding factors that influence the practice of dengue prevention within a university community becomes important. This study aimed to examine the factors affecting dengue knowledge, attitude and preventive practices amongst students and staff of a public university. A cross-sectional survey study was conducted in Kuala Lumpur, Malaysia. A total of 372 students and staff of the NDUM were recruited by stratified sampling method. Data were collected via self-administered pre-tested structured questionnaires covering socio-demography and dengue KAP. Data were analysed descriptively. For bivariate analysis, Chi square test was applied. To explore the factors independently associated with the practice of dengue prevention, a logistic regression model was introduced. Overall, the participants had moderate dengue-related knowledge, good attitudes and good preventive practices. The majority had misconceptions about mosquito biting habits (83.8 %), seasonality of dengue epidemics (73.2 %), and mosquito breeding sites (70.3 %). Staff were more likely to have good dengue-related knowledge (p < 0.001) and attitudes (p = 0.008) than students. There was statistically significant positive association between the level of dengue knowledge and monthly average household income (p = 0.008), age (p < 0.001) and education (p < 0.001). Having good attitudes towards dengue was associated with being a non-Malay (p = 0.034), having higher monthly average household income (p = 0.047) and tertiary education (p < 0.001). In regression analysis, only dengue knowledge and dengue attitudes were significantly and positively associated with practice of dengue prevention. Dengue preventive strategies amongst university students and staff should focus on maintaining good dengue-related preventive practices. Educational campaigns should mainly target students, young staff members, and those with lower level of education and income. PMID- 27696138 TI - In Silico Template Selection of Short Antimicrobial Peptide Viscotoxin for Improving Its Antimicrobial Efficiency in Development of Potential Therapeutic Drugs. AB - Rapid increase in antibiotic resistance has posed a worldwide threat, due to increased mortality, morbidity, and expenditure caused by antibiotic-resistant microbes. Recent development of the antimicrobial peptides like viscotoxin (Vt) has been successfully comprehended as a substitute for classical antibiotics. A structurally stable peptide, Vt can enhance antimicrobial property and can be used for various developmental purposes. Thus, structural stability among the antimicrobial peptides, Vt A1 (3C8P), A2 (1JMN), A3 (1ED0), B (1JMP), and C (1ORL) of Viscus album was computationally analyzed. In specific, the static confirmation of VtA3 showed high number of intramolecular interactions, along with an increase in hydrophobicity than others comparatively. Further, conformational sampling was used to analyze various geometrical parameters such as root mean square deviation, root mean square fluctuation, radius of gyration, and ovality which also revealed the structural stability of VtA3. Moreover, the statistically validated contours of surface area, lipophilicity, and distance constraints of disulfide bonds also supported the priority of VtA3 with respect to stability. Finally, the functional activity of peptides was accessed by computing their free energy of membrane association and membrane interactions, which defined VtA3 as functionally stable. Currently, peptide-based antibiotics and nanoparticles have attracted the pharmaceutical industries for their potential therapeutic applications. Thereby, it is proposed that viscotoxin A3 (1ED0) could be used as a preeminent template for scaffolding potentially efficient antimicrobial peptide-based drugs and nanomaterials in future. PMID- 27696139 TI - Promoting Tag Removal of a MBP-Fused Integral Membrane Protein by TEV Protease. AB - Tag removal is a prerequisite issue for structural and functional analysis of affinity-purified membrane proteins. The present study took a MBP-fused membrane protein, MrpF, as a model to investigate the tag removal by TEV protease. Influences of the linking sequence between TEV cleavage site and MrpF on protein expression and predicted secondary structure were investigated. The steric accessibility of TEV protease to cleavage site of MBP-fused MrpF was explored. It was found that reducing the size of hydrophilic group of detergents and/or extending the linking sequence between cleavage site and target protein can significantly improve the accessibility of the cleavage site and promote tag removal by TEV protease. PMID- 27696140 TI - Use of Swine Wastewater as Alternative Substrate for Mycelial Bioconversion of White Rot Fungi. AB - Seven white rot fungal species were tested for growth as mycelia using swine wastewater (SW), an agro-waste with tremendous environmental footprint, as the sole nutrient source. The SW contained high concentrations of carbon and nitrogen components, which could support nutritional requirements for mycelial growth. Out of the seven species, Pleurotus ostreatus and Hericium erinaceus were successfully cultivated on the SW medium using solid-state fermentation. Response surface methodology was employed to determine the combination of pH, temperature (T), and substrate concentration (C) that maximizes mycelial growth rate (Kr) for the two species. The optimum condition was estimated as pH = 5.8, T = 28.8 degrees C, and C = 11.2 g chemical oxygen demand (COD)/L for P. ostreatus to yield Kr of 11.0 mm/day, whereas the greatest Kr (3.1 mm/day) was anticipated at pH = 4.6, T = 25.5 degrees C, and C = 11.9 g COD/L for H. erinaceus. These Kr values were comparable to growth rates obtained using other substrates in the literature. These results demonstrate that SW can be used as an effective substrate for mycelial cultivation of the two white rot fungal species, suggesting an alternative method to manage SW with the production of potentially valuable biomass. PMID- 27696141 TI - Recovery of Phenolic Acid and Enzyme Production from Corn Silage Biologically Treated by Trametes versicolor. AB - Corn silage is used as high-energy forage for dairy cows and more recently for biogas production in a process of anaerobic co-digestion with cow manure. In this work, fresh corn silage after the harvest was used as a substrate in solid-state fermentations with T. versicolor with the aim of phenolic acid recovery and enzyme (laccase and manganese peroxidase) production. During 20 days of fermentation, 10.4-, 3.4-, 3.0-, and 1.8-fold increments in extraction yield of syringic acid, vanillic acid, p-hydroxybenzoic acid, and caffeic acid, respectively, were reached when compared to biologically untreated corn silage. Maximal laccase activity was gained on the 4th day of fermentation (V.A. = 180.2 U/dm3), and manganese peroxidase activity was obtained after the 3rd day of fermentation (V.A. = 30.1 U/dm3). The addition of copper(II) sulfate as inducer during solid state fermentation resulted in 8.5- and 7-fold enhancement of laccase and manganese peroxidase activities, respectively. Furthermore, the influence of pH and temperature on enzyme activities was investigated. Maximal activity of laccase was obtained at T = 50 degrees C and pH = 3.0, while manganese peroxidase is active at temperature range T = 45-70 degrees C with the maximal activity at pH = 4.5.

A processing account of generation effects on context memory (Mulligan in Journal of Experimental Psychology: Learning, Memory, and Cognition, 30(4), 838-855, 2004; Mulligan, Lozito, & Rosner in Journal of Experimental Psychology: Learning, Memory, and Cognition, 32(4), 836-846, 2006) proposes that these effects depend on whether the generation task causes any shift in processing of the type of context features for which memory is being tested. Mulligan and colleagues have used this account to predict various negative effects of generation on context memory, but the account also predicts positive generation effects under certain circumstances. The present experiment provided a critical test of the processing account by examining how generation affected memory for auditory rather than visual context. Based on the processing account, we predicted that generation of rhyme words should enhance processing of auditory information associated with the words (i.e., voice gender), whereas generation of antonym words should have no effect. These predictions were confirmed, providing support to the processing account.

AB - It remains unclear if differences in bone mineral density (BMD) exist at different skeletal sites between people with schizophrenia and age- and sex matched healthy controls (HCs). Major databases were searched from inception until February 2016 for studies measuring BMD using dual-energy X-ray absorptiometry (DXA) at any skeletal site in individuals with schizophrenia. Ten studies investigating 827 people with schizophrenia (55.4 % female, 33.8 +/- 9.7 years) and 1379 HCs (58.7 % female, 34.7 +/- 9.1 years) were included. People with schizophrenia had significantly reduced BMD at the lumbar spine (standardised mean difference adjusted for publication bias (SMD) = -0.950 (95 % CI = -1.23 to -0.66, fail-safe number = 825) and hip (SMD = -0.534, 95 % CI = 0.876 to -0.192, fail-safe number = 186). A higher proportion of hyperprolactinaemia (beta = -0.0102, p < 0.0001) and smokers (beta = -0.0099, p = 0.02) moderated a larger reduced BMD at the lumbar spine. Further research is required to investigate if low bone mass and fractures can be prevented in people with schizophrenia.

AB - Among the several aspects involved into the synthesis of monocharged nitrogene vacancy N V - colored centers produced into nanodiamonds ND, the post-annealing cleaning process, such as sulfo-nitric acid cleaning or thermal oxidation under acid conditions, can be seen as a factor impacting the optical response of these N V - colored centers. A significative difference of optical response is in fact noticed modifying the post-annealing treatment conditions, between a pure oxidative treatment at room temperature and a mixed-process including oxidation and thermal activation. Specific chemical processes and surface chemical aspects are proposed to explain the optical signals obtained by fluorescence. Some chemical pathways are then found more efficient than others to limit the fluorescence quenching of these colored N V - emitters. PMID- 27696147 TI - Relapsing Polychondritis: A Review and Guide for the Dermatologist. AB - Relapsing polychondritis, or RP, is a rare connective tissue disease characterized by relapsing-remitting destructive inflammation of the cartilaginous and other proteoglycan-rich structures in the body. Given the relatively low incidence of RP, a concise clinically relevant guide, focusing on the cutaneous manifestations of this serious disease, is lacking. In this review, we provide the dermatologist with an approach to diagnosing RP and a guide to its initial work-up, and management. We close with an overview of the currently available treatment modalities for RP. PMID- 27696148 TI - Frequency and analysis of non-clinical errors made in radiology reports using the National Integrated Medical Imaging System voice recognition dictation software. AB - BACKGROUND: Voice recognition (VR) dictation of radiology reports has become the mainstay of reporting in many institutions worldwide. Despite benefit, such software is not without limitations, and transcription errors have been widely reported. AIM: Evaluate the frequency and nature of non-clinical transcription error using VR dictation software. METHODS: Retrospective audit of 378 finalised radiology reports. Errors were counted and categorised by significance, error type and sub-type. Data regarding imaging modality, report length and dictation time was collected. RESULTS: 67 (17.72 %) reports contained >=1 errors, with 7 (1.85 %) containing 'significant' and 9 (2.38 %) containing 'very significant' errors. A total of 90 errors were identified from the 378 reports analysed, with 74 (82.22 %) classified as 'insignificant', 7 (7.78 %) as 'significant', 9 (10 %) as 'very significant'. 68 (75.56 %) errors were 'spelling and grammar', 20 (22.22 %) 'missense' and 2 (2.22 %) 'nonsense'. 'Punctuation' error was most common sub type, accounting for 27 errors (30 %). Complex imaging modalities had higher error rates per report and sentence. Computed tomography contained 0.040 errors per sentence compared to plain film with 0.030. Longer reports had a higher error rate, with reports >25 sentences containing an average of 1.23 errors per report compared to 0-5 sentences containing 0.09. CONCLUSION: These findings highlight the limitations of VR dictation software. While most error was deemed insignificant, there were occurrences of error with potential to alter report interpretation and patient management. Longer reports and reports on more complex imaging had higher error rates and this should be taken into account by the reporting radiologist. PMID- 27696150 TI - In Vitro andIn Vivo induction of bone formation using a recombinant adenoviral vector carrying the human BMP-2 gene. AB - It has been well established that bone morphogenetic protein-2 (BMP-2) can induce bone formation bothin vivo andin vitro, although high concentrations (up to milligrams) of BMP-2 have been required to achieve this effectin vivo. Further, clinical applications are usually limited to a single dose at the time of implantation. In an attempt to prolong the transforming effect of BMP-2 we used a recombinant adenoviral vector carrying the human BMP-2 gene (Adv-BMP2) to transduce marrow-derived mesenchymal stem cells (MSC) of skeletally mature male New Zealand white rabbits. The pluripotential MSC were incubated with Adv-BMP2 overnight followed by culture in growth medium for 1 week. Assays on tissue cultures demonstrated that these Adv-BMP2 transduced MSC produced BMP-2 protein, differentiated into an osteoprogenitor line, and induced bone formationin vitro. These MSC had increased alkaline phosphatase activity, increased expression of type I collagen, osteopontin, and osteocalcin mRNA, and induced matrix mineralization compared with both nontransduced cells and cells transduced with a control adenoviral construct. To analyze the osteogenic potentialin vivo, Adv BMP2-transduced MSC were autologously implanted into the intertransverse process space between L5 and L6 of the donor rabbits. The production of new bone was demonstrated by radiographic examination 4 weeks later in areas implanted with cells transduced with Adv-BMP2, whereas no bone was evident at sites implanted with cells transduced with the control adenoviral construct. Histological examination further confirmed the presence of new bone formation. These accumulated data indicate that it is possible to successfully transduce mesenchymal stem cells with a recombinant adenoviral vector carrying the gene for BMP-2 such that these cells will produce BMP-2, differentiate into an osteoprogenitor line, and induce bone formation bothin vitro andin vivo. Moreover, incubation of the Adv-BMP2-transduced cells for an additional 7 days in culture before transplantation enhances the success rate in bone formation (three out of three) as compared with our previous report (one out of five, Calcif Tissue Int 63:357-360, 1998). PMID- 27696149 TI - Generation of IL10 and TGFB1 coexpressed mice displaying resistance to ovalbumin induced asthma. AB - Asthma is a common chronic inflammatory disease in the airways with wide prevalence, and it is thought to be caused by the combinational factors in environment and genetics. A large body of studies has suggested that cell immunity played a vital role in regulating the airway hyperreactivity (AHR) and inflammation. Therefore, we here developed a mouse model of asthma by microinjecting the pronucleus with a vector spontaneously coding human IL10 and TGFB1 gene to explore the possible interaction between these two potent molecules during asthma progression. From the total 35 newborn mice, we successfully obtained 3 founders expressing exogenous genes. In the transgenic mice, we observed profoundly enhanced expression of IL10 and TGFB1. In the condition of ovalbumin challenge, transgenic mice displayed a 1.9-fold higher MCh50 score than wild-type counterparts, indicating reminiscent AHR. Meanwhile, a three-fold decrease of cell counts in bronchoalveolar lavage fluid (BALF) was recorded as well. These results suggested that IL10 and TGFB1 cooperatively protected the respiratory system in response to antigenic stimulus. To interrogate the respective behaviors of the two genes, we quantified the expression of downstream genes in IL10 signaling or TGFB1 signaling. We observed that the examined genes in IL10 signaling were significantly repressed, especially IL5, which showed 5.4 fold decreased expression. Most genes were not altered in TGFB1 signaling, and the production of endogenous TGFB1 was significantly inhibited. These evidences collectively proved that the activation of IL0 and TGFB1 protected the host from antigen-induced asthma, possibly through IL10 signaling. This study shed some light on the modulations of IL10 and TGFB1, and related networks to asthma progression. PMID- 27696151 TI - Baseline expression and effect of TGF-beta1 on Type I and III collagen mRNA and protein synthesis in human odontoblasts and pulp cellsIn Vitro. AB - Since growth factors have been suggested to regulate dentin collagen formation in response to external irritation, we investigated the effect of TGF-beta1 on proalpha1(I) collagen mRNA expression in cultured mature human odontoblasts and pulpal fibroblasts, as well as cultured human pulp tissue, using quantitative PCR. Cultured gingival fibroblasts (GF) and osteoblasts (OB) served as controls. Also, type I collagen synthesis in cultured odontoblasts and pulp tissue, as well as type III collagen synthesis in odontoblasts, were studied by measuring respective procollagen (PINP and PIIINP) secretion into culture media with radioimmunoassay (RIA). Odontoblasts expressed significantly higher basic level of type I collagen mRNA than pulp tissue or pulp fibroblasts in culture, but markedly lower level than GF and OB cells. TGF-beta1 (10 ng/ml) had negligible effects on type I collagen mRNA expression or PINP synthesis in cultured odontoblasts and pulp tissue, and PIIINP synthesis in the odontoblasts. In PF cells, the effect of TGF-beta1 depended on culturing conditions; a 6-fold increase in mRNA expression was observed using serum-free medium but no effect was seen in the cells cultured with 10% FBS. In contrast, GF cells serving as controls were not markedly affected by the culture conditions, with 2-3-fold increase in mRNA expression by TGF-beta1. These experiments demonstrate that mature human odontoblasts are capable of synthesizing type III collagen protein, and that TGF-beta1 has negligible effect on mature human odontoblast and pulp tissue collagen expression. PMID- 27696155 TI - Employing an open-source tool to assess astrocyte tridimensional structure. AB - Astrocytes display important features that allow them to maintain a close dialog with neurons, ultimately impacting brain function. The complex morphological structure of astrocytes is crucial to the role of astrocytes in brain networks. Therefore, assessing morphologic features of astrocytes will help provide insights into their physiological relevance in healthy and pathological conditions. Currently available tools that allow the tridimensional reconstruction of astrocytes present a number of disadvantages, including the need for advanced computational skills and powerful hardware, and are either time consuming or costly. In this study, we optimized and validated the FIJI-ImageJ, Simple Neurite Tracer (SNT) plugin, an open-source software that aids in the reconstruction of GFAP-stained structure of astrocytes. We describe (1) the loading of confocal microscopy Z-stacks, (2) the selection criteria, (3) the reconstruction process, and (4) the post-reconstruction analysis of morphological features (process length, number, thickness, and arbor complexity). SNT allows the quantification of astrocyte morphometric parameters in a simple, efficient, and semi-automated manner. While SNT is simple to learn, and does not require advanced computational skills, it provides reproducible results, in different brain regions or pathophysiological states. PMID- 27696156 TI - Dendritic-branching angles of pyramidal neurons of the human cerebral cortex. AB - In this article, we analyze branching angles of the basal dendrites of pyramidal neurons of layers III and V of the human temporal cortex. For this, we use a novel probability directional statistical distribution called truncated von Mises distribution that is able to describe more accurately the dendritic-branching angles than the previous proposals. Then, we perform comparative studies using this statistical method to determine similarities and/or differences between branches and branching angles that belong to different cortical layers and regions. Using this methodology, we found that common design principles exist and govern the patterns found in the different branches that compose the basal dendrites of human pyramidal cells of the temporal cortex. However, particular differences were found between supra and infragranular cells. Furthermore, we compared the branching angles of human layer III pyramidal neurons with data obtained in the previous studies in layer III of both the rat somatosensory cortex and of several cortical areas of the mouse. Finally, we study the branching angle differences between the humans that compose our data. PMID- 27696157 TI - Prolonged fibroblast growth factor 19 response in patients with primary sclerosing cholangitis after an oral chenodeoxycholic acid challenge. AB - BACKGROUND: Bile salts likely contribute to liver injury in patients with primary sclerosing cholangitis (PSC) and primary biliary cholangitis (PBC). Fibroblast growth factor 19 (FGF19) is a bile salt-induced enterokine with hepatoprotective potential as it suppresses de novo bile salt synthesis. Here, we evaluated the bile salt receptor FXR/FGF19 gut-liver axis in PSC and PBC patients. METHODS: Fasted patients with PSC (n = 12) and PBC (n = 10), and healthy controls (HC; n = 10) were orally challenged with the natural FXR agonist chenodeoxycholic acid (CDCA 15 mg/kg). Blood was sampled hourly until 8 h afterwards. Serum FGF19 and bile salt excursions were determined. Serum levels of 7alpha-hydroxy-4-cholesten 3-one (C4), reflecting bile salt synthesis, were measured as a biomarker of FGF19 response. RESULTS: Baseline serum FGF19 levels were comparable between groups, while fasted bile salt levels in PSC patients were elevated. Upon CDCA challenge, HC and PBC patients showed a serum FGF19 peak after 4 h followed by a decline. PSC patients showed a prolonged and elevated serum FGF19 response up to 8 h, combined with a sustained serum elevation of CDCA and other bile salts. In general, C4 levels declined following FGF19 elevation. In PSC patients with less favorable prognosis, baseline C4 levels were drastically suppressed and did not further decline. CONCLUSION: Following an oral CDCA challenge, PSC patients showed an impaired clearance of CDCA and a prolonged serum FGF19 response. FXR agonist therapy in PSC could cause prolonged exposure to elevated levels of FGF19, and we propose careful monitoring for detrimental side effects in patient studies. PMID- 27696158 TI - Vortex-assisted ionic liquid-based dispersive liquid-liquid microextraction for assessment of chromium species in artificial saliva extract of different chewing tobacco products. AB - A novel dispersive liquid-liquid microextraction (ILDLLMUE) method using an extracting solvent (ionic liquid) and dispersant (Triton X-114) was developed for the separation and preconcentration of hexavalent chromium (Cr6+) in artificial saliva extract (ASE) of chewing tobacco products, gutkha, and mainpuri (n = 23). In the proposed method, the extraction of Cr6+ was accomplished by using ammonium pyrrolidinedithiocarbamate (APDC) as complexing agent and 1-butyl-3 methylimidazolium hexafluorophosphate [C4MIM] [PF6] as extracting solvent. The tiny droplet of metal chelate was then dispersed into TX-114 emulsion, using vortex mixer. Various parameters such as concentration of APDC, pH of the solution, volume of [C4MIM] [PF6], and TX-114 as well as extraction time were studied. Under the most favorable conditions, the limit of detection was found to be 0.068 MUg/L with the relative standard deviation <5 %. The enrichment factor of developed method was found as 62.5, and method has been effectively applied for the analysis of Cr species in artificial saliva extract of gutkha and mainpuri products. The Cr6+ was quantitatively recovered (<97 %) under optimal conditions, while the recovery of trivalent specie (Cr3+), at the same experimental conditions, was observed to be <5 %. The Cr3+ was determined by the difference of total Cr and Cr6+ in artificial saliva extract of selected STP. Health risks associated with the intake of total Cr in gutkha and mainpuri were assessed in terms of estimated daily intake, such as carcinogenic and noncarcinogenic risks. Estimated daily intake of Cr via chewing 10 g/day of gutkha and mainpuri was found to be below the maximum tolerable daily intake, whereas the calculated risk of cancer for Cr was observed in the acceptable range of 10E-6-10E-4, except some brands of gutkha.

AB - This study examined the long-term effects of the landfill disposal of untreated urban waste for soil fertilization on the prevalence and antibiotic resistance profiles of various human opportunistic pathogens in soils from Burkina Faso. Samples were collected at three sites in the periphery of Ouagadougou during two campaigns in 2008 and 2011. At each site, amendment led to changes in physico chemical characteristics as shown by the increase in pH, CEC, total C, total N, and metal contents. Similarly, the numbers of total heterotrophic bacteria were higher in the amended fields than in the control ones. No sanitation indicators, i.e., coliforms, Staphylococci, and Enterococci, were detected. Pseudomonas aeruginosa and Burkholderia cepacia complex (Bcc) were detected at a low level in one amended field. Stenotrophomonas maltophilia was detected from both campaigns at the three sites in the amended fields and only once in an unamended field. Diversity analysis showed some opportunistic pathogen isolates to be closely related to reference clinical strains responsible for nosocomial- or community acquired infections in Northern countries. Antibiotic resistance tests showed that P. aeruginosa and Bcc isolates had a wild-type phenotype and that most S. maltophilia isolates had a multi-drug resistance profile with resistance to 7 to 15 antibiotics. Then we were able to show that amendment led to an increase of some human opportunistic pathogens including multi-drug resistant isolates. Although the application of untreated urban waste increases both soil organic matter content and therefore soil fertility, the consequences of this practice on human health should be considered. PMID- 27696162 TI - Effect of carbon sources on the aggregation of photo fermentative bacteria induced by L-cysteine for enhancing hydrogen production. AB - Poor flocculation of photo fermentative bacteria resulting in continuous biomass washout from photobioreactor is a critical challenge to achieve rapid and stable hydrogen production. In this work, the aggregation of Rhodopseudomonas faecalis RLD-53 was successfully developed in a photobioreactor and the effects of different carbon sources on hydrogen production and aggregation ability were investigated. Extracellular polymeric substances (EPS) production by R. faecalis RLD-53 cultivated using different carbon sources were stimulated by addition of L cysteine. The absolute zeta potentials of R. faecalis RLD-53 were considerably decreased with addition of L-cysteine, and aggregation barriers based on DLVO dropped to 15-43 % of that in control groups. Thus, R. faecalis RLD-53 flocculated effectively, and aggregation abilities of strain RLD-53 cultivated with acetate, propionate, lactate and malate reached 29.35, 32.34, 26.07 and 24.86 %, respectively. In the continuous test, hydrogen-producing activity was also promoted and reached 2.45 mol H2/mol lactate, 3.87 mol H2/mol propionate and 5.10 mol H2/mol malate, respectively. Therefore, the aggregation of R. faecalis RLD-53 induced by L-cysteine is independent on the substrate types, which ensures the wide application of this technology to enhance hydrogen recovery from wastewater dominated by different organic substrates. PMID- 27696160 TI - Studies on photodegradation process of psychotropic drugs: a review. AB - Consumption of psychotropic drugs is still increasing, especially in high-income countries. One of the most crucial consequences of this fact is significant release of them to the environment. Considerable amounts of atypical antipsychotics, benzodiazepines, antidepressants, and their metabolites were detected in river, lake, and sea water, as well as in tissues of aquatic organisms. Their ecotoxicity was proved by numerous studies. It should be noticed that interaction between psychotropic pharmaceuticals and radiation may lead to formation of potentially more toxic intermediates. On the other hand, photo assisted wastewater treatment methods can be used as an efficient way to eliminate them from the environment. Many methods based on photolysis and photocatalysis were proposed and developed recently; nevertheless, the problem is still unsolved. However, according to recent studies, photocatalysis could be considered as the most promising and far more effective than regular photolysis. An overview on photolytic as well as homogenous and heterogeneous photocatalytic degradation methods with the use of various catalysts is presented. The photostability and phototoxicity of pharmaceuticals were also discussed. Various analytical methods were used for the photodegradation research, and this issue was also compared and summarized. Use of high-resolution multistage mass spectrometry (Q-TOF, ion trap, Orbitrap) was suggested. The combined techniques such as LC-MS, GC-MS, and LC-NMR, which enable qualitative and quantitative analyses in one run, proved to be the most valuable in this case. Assembling of MS/MS spectra libraries of drug molecules and their phototransformation products was identified as the future challenge. PMID- 27696164 TI - Suppression of PCDD/Fs during thermal desorption of PCBs-contaminated soil. AB - Thermal treatment of polychlorinated biphenyls (PCBs) contaminated soil was shown in earlier work to generate new PCBs, as well as polychlorinated dibenzo-p dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs). In this study, this thermal desorption was conducted with addition of three distinct inhibitors, including ammonium sulphate, urea and calcium oxide, to inhibit the formation of PCDDs and PCDFs when remediating PCBs-contaminated soil. Experiments were conducted for 40 min at 400 degrees C after adding 1 wt.% of inhibitor. Both the total PCDD/Fs and international toxic equivalent quantity (I-TEQ) reduced when inhibitors were introduced. Of the three compounds tested, CaO shows the highest inhibition efficiency, 92.2 % for total PCDD/Fs and 95.6 % for I-TEQ. The amount of CaO added also influences the suppression efficiency of PCDD/Fs. These results suggest that promoting desorption and destruction of precursors is probably the mechanism of suppression. PMID- 27696163 TI - Anxiety and memory deficits induced by tannery effluent in C57BL/6J female mice. AB - This study aimed to evaluate the behavior of female C57Bl/6J mice exposed to tannery effluents diluted in drinking water. Female mice were divided into a control group, in which the animals received only drinking water, and experimental groups, which received raw tannery effluent in 7.5 and 15 % concentrations diluted in water (period of 60 days). In the last experimental week, the mice (in diestrus phase) were subjected to different behavioral tests: elevated plus-maze, open-field test, forced swim test, and object recognition test. Our data demonstrated that exposure to tannery effluent increased the anxiety index of animals and decreased the locomotion ratio in the central quadrants/total, indicating an increase in anxiety-like behavior. Regarding the forced swim test, we did not observe changes in the evaluated behaviors. There were no statistically significant differences in the recognition index of the novel and familiar object in the groups exposed to tannery effluent compared with the control group, indicating a possible influence of the constituents of tannery effluent on cognition. Thus, our findings support the hypothesis that effluents, containing neurotoxic substances, could cause behavioral disruptions in female C57Bl/6J mice. PMID- 27696166 TI - Urban biowaste-derived sensitizing materials for caffeine photodegradation. AB - Caffeine-photosensitized degradation has been studied in the presence of bio based materials derived from urban biowaste after aerobic aging. A peculiar fraction (namely bio-based substances (BBSs)), soluble in all the pH range, has been used as photosensitizing agent. Several caffeine photodegradation tests have been performed, and positive results have been obtained in the presence of BBSs and H2O2, without and with additional Fe(II) (photo-Fenton-like process). Moreover, hybrid magnetite-BBS nanoparticles have been synthesized and characterized, in order to improve the sensitizer recovery and reuse after the caffeine degradation. In the presence of such nanoparticles and H2O2 and Fe(II), the complete caffeine degradation has been attained in very short time. Both homogeneous and heterogeneous processes were run at pH = 5, milder condition compared to the classic photo-Fenton process. PMID- 27696165 TI - Glial markers and emotional memory in rats following acute cerebral radiofrequency exposures. AB - The widespread mobile phone use raises concerns on the possible cerebral effects of radiofrequency electromagnetic fields (RF EMF). Reactive astrogliosis was reported in neuroanatomical structures of adaptive behaviors after a single RF EMF exposure at high specific absorption rate (SAR, 6 W/kg). Here, we aimed to assess if neuronal injury and functional impairments were related to high SAR induced astrogliosis. In addition, the level of beta amyloid 1-40 (Abeta 1-40) peptide was explored as a possible toxicity marker. Sprague Dawley male rats were exposed for 15 min at 0, 1.5, or 6 W/kg or for 45 min at 6 W/kg. Memory, emotionality, and locomotion were tested in the fear conditioning, the elevated plus maze, and the open field. Glial fibrillary acidic protein (GFAP, total and cytosolic fractions), myelin basic protein (MBP), and Abeta1-40 were quantified in six brain areas using enzyme-linked immunosorbent assay. According to our data, total GFAP was increased in the striatum (+114 %) at 1.5 W/kg. Long-term memory was reduced, and cytosolic GFAP was increased in the hippocampus (+119 %) and in the olfactory bulb (+46 %) at 6 W/kg (15 min). No MBP or Abeta1-40 expression modification was shown. Our data corroborates previous studies indicating RF EMF-induced astrogliosis. This study suggests that RF EMF-induced astrogliosis had functional consequences on memory but did not demonstrate that it was secondary to neuronal damage. PMID- 27696167 TI - Mitigation of cadmium-induced lung injury by Nigella sativa oil. AB - Induction of oxidative stress and inflammation are considered the primary mechanism of cadmium (Cd) toxicity. Nigella sativa (NS) seeds and their oil (NSO) have been reported to possess antioxidant and anti-inflammatory potential. This study was conducted to assess the protective effect of NSO on Cd-induced lung damage in rat. Forty adult male Wistar rats were divided equally into 4 groups. Animals in groups I, II, and III received 1 ml of isotonic saline intraperitoneally (IP), 2 mg/kg of cadmium chloride (CdCl2) dissolved in isotonic saline IP, and 1 ml/kg of NSO by gastric gavage, respectively. Group IV rats received NSO an hour prior to CdCl2 administration via the same routes and doses as previously described. All animals were treated for 28 days. At the end of the study, animals were sacrificed; lungs were harvested for histopathological studies using light and electron microscopy. Saline-treated and NSO-treated rats showed normal lung parenchyma. However, CdCl2-treated rats showed massive degenerative changes in alveolar epithelial lining, disrupted interalveolar septa, and hemolytic debris in alveoli. Rats treated with both NSO and CdCl2 (group IV) showed amelioration of most Cd-induced lung damage with minimal histopathological changes in lung architecture. This study elucidates the protective effects of NSO on Cd-induced lung injury in rats and highlights the possibility of using NSO as a protective agent in individuals at high risk of Cd induced lung toxicity. PMID- 27696168 TI - Heavy metals in surface sediments of the shallow lakes in eastern China: their relations with environmental factors and anthropogenic activities. AB - The aquatic environment is affected by heavy metal pollution. This study was conducted to test the hypothesis that environmental factors and anthropogenic activities influence the distributions and the risks posed by heavy metals in surface sediments in shallow lakes in eastern China, which is an area affected by rapid urbanization, industrialization, and population growth. Total Cd, Cr, Cu, Ni, Pb, Se, and Zn concentrations in sediment samples were determined using inductively coupled plasma optical emission spectrometry. The I geo showed that sediments in the lakes were moderately polluted with Cr, Cu, Pb, and Zn, and the EF method showed that Cd and Se were significantly enriched in lakes. The heavy metals were found to pose moderate risks in most of the lakes, except for Gaoyou Lake, Honghu Lake, Poyang Lake, and Weishan Lake. The RI method indicated that very high risks were posed in Dongting Lake and Poyang Lake. Cd was found to pose much higher levels of risk than the other metals. Significant correlations were found between the heavy metal concentrations and the total carbon, nitrogen, phosphorus, and sulfur concentrations. The gross domestic product represented anthropogenic activities well. The gross domestic product of an area and the gross domestic products of primary and secondary industries in an area all had significant relationships with the concentrations of Cu and Pb, indicating that anthropogenic activities have different impacts on pollution with different heavy metals. The gross domestic product index was found to be a driving force behind the pollution of lakes with heavy metals. PMID- 27696169 TI - Prior Radiotherapy Does Not Affect Abdominal Wall Reconstruction Outcomes: Evidence from Propensity Score Analysis. AB - BACKGROUND: Prior abdominal wall radiotherapy (XRT) adversely affects wound healing, but data are limited on how prior XRT may affect abdominal wall reconstruction (AWR) outcomes. The purpose of this study was to determine whether prior abdominal wall radiotherapy is associated with a higher incidence of complications following AWR for a hernia or oncologic resection defect. METHODS: We performed a retrospective study of consecutive patients who underwent complex AWR using acellular dermal matrix (ADM) at a single center. We compared outcomes between patients who underwent prior XRT that directly involved the abdominal wall and those who did not receive XRT. Propensity score match-paired and multivariate analyses were performed. RESULTS: A total of 511 patients (130 [25.4 %] with prior XRT; 381 [74.6 %] without prior XRT) underwent AWR with ADM for repair of a complex hernia or oncologic resection defect. Mean follow-up was 31.4 months, mean XRT dose was 48.9 Gy, and mean time between XRT and reconstruction was 19.2 months. XRT AWR patients underwent more flap reconstructions (14.6 vs. 5.0 %, P < 0.001) but fewer component separations (61.5 vs. 71.4 %; P = 0.036) than non-XRT AWR patients. The two groups had similar rates of hernia recurrence (8.5 vs. 9.4 %; P = 0.737) and surgical site occurrence (25.4 vs. 23.4 %; P = 0.640). In the propensity score-matched subgroups, there were no differences in hernia recurrence, surgical site occurrence, and wound healing complication rates. CONCLUSIONS: Prior XRT does not adversely affect outcomes in AWR. However, surgeons should be aware of the higher likelihood of needing a soft tissue flap reconstruction for soft tissue replacement when performing AWR after XRT. PMID- 27696170 TI - KRAS Mutation Status Dictates Optimal Surgical Margin Width in Patients Undergoing Resection of Colorectal Liver Metastases. AB - BACKGROUND: The optimal tumor-free margin width remains controversial and may be inappropriate to investigate without considering differences in the underlying tumor biology. METHODS: R1 resection was defined as margin clearance less than 1 mm. R0 resection was further divided into 3 groups: 1-4, 5-9, and >=10 mm. The impact of margin width on overall survival (OS) relative to KRAS status [wild type (wtKRAS) vs. mutated (mutKRAS)] was assessed. RESULTS: A total of 411 patients met inclusion criteria. Median patient age was 58 years (interquartile range, 49.7-66.7); most patients were male (n = 250; 60.8 %). With a median follow-up of 28.3 months, median and 5-year OS were 69.8 months and 55.1 %. Among patients with wtKRAS tumors, although margin clearance of 1-4 mm or more was associated with improved OS compared to R1 (all P < 0.05), no difference in OS was observed when comparing margin clearance of 1-4 mm to the 5-9 mm and the >=10 mm groups (all P > 0.05). In contrast, among patients with mutKRAS tumors, all three groups of margin clearance (1-4, 5-9, and >=10 mm) fared no better in terms of 5-year survival compared to R1 resection (all P > 0.05). CONCLUSIONS: While a 1-4 mm margin clearance in patients with wtKRAS tumors was associated with improved survival, wider resection width did not confer an additional survival benefit. In contrast, margin status-including a 1 cm margin-did not improve survival among patients with mutKRAS tumors.

PMID- 27696172 TI - Clinical Significance of C-MET Overexpression and Epidermal Growth Factor Receptor Mutation in Platinum-Based Adjuvant Chemotherapy Outcome in Surgically Resected Lung Adenocarcinoma. AB - PURPOSE: We retrospectively assessed the role of C-MET expression and epidermal growth factor receptor (EGFR) mutation on survival following platinum-based adjuvant chemotherapy. The impact of C-MET on survival was also investigated in relation to EGFR mutation status. METHODS: We enrolled 311 patients with resected lung adenocarcinoma (high-risk stage 1B-3A), and performed immunohistochemistry (IHC) using C-MET- and mutant EGFR (EGFRmut)-specific antibodies in tissue microarrays. RESULTS: Adjuvant chemotherapy was administered to 151 patients, 96 of whom relapsed and 85 died by the end of the study. On IHC, C-MET and EGFRmut were positive in 141 (45.3 %) and 88 (28.3 %) cases, respectively. On univariate analysis, adjuvant chemotherapy prolonged relapse-free survival (RFS) and overall survival (OS) in C-MET(+) patients (RFS p = 0.035; OS p = 0.013) but not in C MET(-) patients. On multivariate analysis, adjuvant chemotherapy was a positive independent prognostic factor in C-MET(+) (RFS p = 0.013; OS p = 0.006) but not in C-MET(-) patients. In addition, univariate analysis showed no effect of EGFRmut status on RFS and OS after chemotherapy, whereas multivariate analysis revealed that adjuvant chemotherapy increased RFS in both EGFRmut(+) and EGFRmut( ) patients [EGFRmut(+) p = 0.033; EGFRmut(-) p = 0.030]. C-MET was a negative prognostic factor for RFS (p = 0.045) and OS (p = 0.007) in the EGFRmut(-) group but not in the EGFRmut(+) group, on multivariate analysis. CONCLUSIONS: Our data indicate that patients with C-MET overexpression should be considered for adjuvant chemotherapy, and that C-MET negatively correlates with survival in patients with wild-type, but not mutant, EGFR.

AB - In April 2015, Oregon Health & Science University (OHSU) deployed a web-based, electronic medical record-embedded application created by third party vendor Vynca Inc. to allow real-time education, and completion of Physician Orders for Life Sustaining Treatment (POLST). Forms are automatically linked to the Epic SystemsTM electronic health record (EHR) patient header and submitted to a state Registry, improving efficiency, accuracy, and rapid access to and retrieval of these important medical orders. POLST Forms, implemented in Oregon in 1992, are standardized portable medical orders used to document patient treatment goals for end-of-life care. In 2009, Oregon developed the first POLST-only statewide registry with a legislative mandate requiring POLST form signers to register the form unless the patient opts out. The Registry offers 24/7 emergency access to POLST Forms for Emergency Medical Services, Emergency Departments, and Acute Care Units. Because POLST is intended for those nearing end of life, immediate access to these forms at the time of an emergency is critical. Delays in registering a POLST Form may result in unwanted treatment if the paper form is not immediately available. An electronic POLST Form completion system (ePOLST) was implemented to support direct Registry submission. Other benefits of the system include single sign-on, transmission of HL7 data for patient demographics and other relevant information, elimination of potential errors in form completion using internalized logic, built-in real-time video and text-based education materials for both patients and health care professionals, and mobile linkage for signature capture. PMID- 27696174 TI - A Provably Secure Aggregate Signature Scheme for Healthcare Wireless Sensor Networks. AB - Wireless sensor networks (WSNs) are being used in a wide range of applications for healthcare monitoring, like heart rate monitors and blood pressure monitors, which can minimize the need for healthcare professionals. In medical system, sensors on or in patients produce medical data which can be easily compromised by a vast of attacks. Although signature schemes can protect data authenticity and data integrity, when the number of users involved in the medical system becomes huge, the bandwidth and storage cost will rise sharply so that existing signature schemes are inapplicability for WSNs. In this paper, we propose an efficient aggregate signature scheme for healthcare WSNs according to an improved security model, which can combine multiple signatures into a single aggregate signature. The length of such an aggregate signature may be as long as that of an individual one, which can greatly decrease the bandwidth and storage cost for networks. PMID- 27696175 TI - m2-ABKS: Attribute-Based Multi-Keyword Search over Encrypted Personal Health Records in Multi-Owner Setting. AB - Online personal health record (PHR) is more inclined to shift data storage and search operations to cloud server so as to enjoy the elastic resources and lessen computational burden in cloud storage. As multiple patients' data is always stored in the cloud server simultaneously, it is a challenge to guarantee the confidentiality of PHR data and allow data users to search encrypted data in an efficient and privacy-preserving way. To this end, we design a secure cryptographic primitive called as attribute-based multi-keyword search over encrypted personal health records in multi-owner setting to support both fine grained access control and multi-keyword search via Ciphertext-Policy Attribute Based Encryption. Formal security analysis proves our scheme is selectively secure against chosen-keyword attack. As a further contribution, we conduct empirical experiments over real-world dataset to show its feasibility and practicality in a broad range of actual scenarios without incurring additional computational burden. PMID- 27696176 TI - Neural Basis of Visual Attentional Orienting in Childhood Autism Spectrum Disorders. AB - We examined spontaneous attention orienting to visual salience in stimuli without social significance using a modified Dot-Probe task during functional magnetic resonance imaging in high-functioning preadolescent children with Autism Spectrum Disorder (ASD) and age- and IQ-matched control children. While the magnitude of attentional bias (faster response to probes in the location of solid color patch) to visually salient stimuli was similar in the groups, activation differences in frontal and temporoparietal regions suggested hyper-sensitivity to visual salience or to sameness in ASD children. Further, activation in a subset of those regions was associated with symptoms of restricted and repetitive behavior. Thus, atypicalities in response to visual properties of stimuli may drive attentional orienting problems associated with ASD. PMID- 27696177 TI - Lexical Processing in Toddlers with ASD: Does Weak Central Coherence Play a Role? AB - This study investigated whether vocabulary delays in toddlers with autism spectrum disorders (ASD) can be explained by a cognitive style that prioritizes processing of detailed, local features of input over global contextual integration-as claimed by the weak central coherence (WCC) theory. Thirty toddlers with ASD and 30 younger, cognition-matched typical controls participated in a looking-while-listening task that assessed whether perceptual or semantic similarities among named images disrupted word recognition relative to a neutral condition. Overlap of perceptual features invited local processing whereas semantic overlap invited global processing. With the possible exception of a subset of toddlers who had very low vocabulary skills, these results provide no evidence that WCC is characteristic of lexical processing in toddlers with ASD. PMID- 27696178 TI - New Oral Anticoagulants and Their Reversal Agents. AB - OPINION STATEMENT: Direct oral anticoagulants (DOAC) are an attractive therapeutic option for anticoagulant treatment in the setting of venous thromboembolism or non-valvular atrial fibrillation. These drugs overall appear to have a lower risk of life-threatening hemorrhage than the vitamin K antagonists. In addition, they demonstrate more predictable and stable pharmacokinetics. Measurement of the degree of anticoagulation is desirable in patients with DOAC-associated hemorrhage, but commonly available coagulation assays show poor sensitivity for degree of DOAC effect. DOAC-specific tests are time consuming and not widely available. All coagulation tests should be interpreted considering the timing of last intake and renal function. When life threatening bleeding occurs, hemostasis should be restored as rapidly as possible. Non-specific prohemostatic drugs may have a role in DOAC reversal, and specific antidotes are at different stages of development. In this review, we provide a summary of DOAC characteristics and an overview of the different therapeutic options available for DOAC reversal. PMID- 27696179 TI - Long-Term Cognitive Improvement After Benfotiamine Administration in Patients with Alzheimer's Disease. AB - To date, we still lack disease-modifying therapies for Alzheimer's disease (AD). Here, we report that long-term administration of benfotiamine improved the cognitive ability of patients with AD. Five patients with mild to moderate AD received oral benfotiamine (300 mg daily) over 18 months. All patients were examined by positron emission tomography with Pittsburgh compound B (PiB-PET) and exhibited positive imaging with beta-amyloid deposition, and three received PiB PET imaging at follow-up. The five patients exhibited cognitive improvement as assayed by the Mini-Mental Status Examination (MMSE) with an average increase of 3.2 points at month 18 of benfotiamine administration. The three patients who received follow-up PiB-PET had a 36.7% increase in the average standardized uptake value ratio in the brain compared with that in the first scan. Importantly, the MMSE scores of these three had an average increase of 3 points during the same period. Benfotiamine significantly improved the cognitive abilities of mild to moderate AD patients independently of brain amyloid accumulation. Our study provides new insight to the development of disease modifying therapy. PMID- 27696180 TI - Contamination by Norovirus and Adenovirus on Environmental Surfaces and in Hands of Conscripts in Two Finnish Garrisons. AB - This study investigated the presence of norovirus and adenovirus, especially enteric adenovirus, on the environmental surfaces (n = 481) and military conscripts' hands (n = 109) in two Finnish garrisons (A and B) in 2013 and 2014. A questionnaire study was conducted to reveal possible correlations between viral findings on the conscripts' hands and their acute gastroenteritis symptoms. In addition to the swab samples, 14 fecal samples were obtained for viral analysis. In total, norovirus was present in 9.0 % of the surface swabs in 2013, whereas enteric adenovirus was present in 0.0 % and non-enteric adenovirus in 9.4 %. In the same year, 2.6 % of the hand swabs contained norovirus, 2.6 % enteric adenovirus, and 40.3 % non-enteric adenovirus. Norovirus GI.6 was continually detected on the surfaces of garrison A, and identical virus was detected in some of the fecal samples. In garrison B, two slightly different norovirus GII.4 strains were present on the surfaces. The questionnaires revealed no recent acute gastroenteritis cases in garrison A, but in garrison B, where the norovirus positive hand swabs were collected, 30.6 % of the conscripts reported of recent symptoms. In 2014, norovirus was rarely detected, but adenovirus was again frequently present, both on the surfaces and hands. Taken together, our results suggest that gastroenteritis outbreaks occurred in 2013, but not in 2014. Due to the low number of hand swabs positive for enteric viruses, no conclusions about associations between viral findings and gastroenteritis symptoms could be drawn. This study increased our understanding of the possible transmission of viruses via contaminated environment and hands. PMID- 27696181 TI - Comparison of excitation energy transfer in cyanobacterial photosystem I in solution and immobilized on conducting glass. AB - Excitation energy transfer in monomeric and trimeric forms of photosystem I (PSI) from the cyanobacterium Synechocystis sp. PCC 6803 in solution or immobilized on FTO conducting glass was compared using time-resolved fluorescence. Deposition of PSI on glass preserves bi-exponential excitation decay of ~4-7 and ~21-25 ps lifetimes characteristic of PSI in solution. The faster phase was assigned in part to photochemical quenching (charge separation) of excited bulk chlorophylls and in part to energy transfer from bulk to low-energy (red) chlorophylls. The slower phase was assigned to photochemical quenching of the excitation equilibrated over bulk and red chlorophylls. The main differences between dissolved and immobilized PSI (iPSI) are: (1) the average excitation decay in iPSI is about 11 ps, which is faster by a few ps than for PSI in solution due to significantly faster excitation quenching of bulk chlorophylls by charge separation (~10 ps instead of ~15 ps) accompanied by slightly weaker coupling of bulk and red chlorophylls; (2) the number of red chlorophylls in monomeric PSI increases twice-from 3 in solution to 6 after immobilization-as a result of interaction with neighboring monomers and conducting glass; despite the increased number of red chlorophylls, the excitation decay accelerates in iPSI; (3) the number of red chlorophylls in trimeric PSI is 4 (per monomer) and remains unchanged after immobilization; (4) in all the samples under study, the free energy gap between mean red (emission at ~710 nm) and mean bulk (emission at ~686 nm) emitting states of chlorophylls was estimated at a similar level of 17-27 meV. All these observations indicate that despite slight modifications, dried PSI complexes adsorbed on the FTO surface remain fully functional in terms of excitation energy transfer and primary charge separation that is particularly important in the view of photovoltaic applications of this photosystem. PMID- 27696182 TI - Mapping the Network of Neuropsychological Impairment in Children with Autism Spectrum Disorder: A Graph Theoretical Analysis. AB - Children with autism spectrum disorder (ASD) exhibit social-communicative impairments. Less is known about the neuropsychological profile of ASD, although cognitive and neuropsychological deficits are evident. We modelled neuropsychological function in 20 children with ASD and 20 sex, age and IQ matched typically-developing controls (ages 7-14) as a network of interacting parameters. Graph theoretical analysis was applied to identify critical topographic regions within this network. Two areas were significantly stronger hubs in typically-developing children, the ability to shift attention (p < 0.001) and overall executive function (p < 0.001). Planning/organization was a stronger hub in the cognitive networks of children with ASD (p = 0.001). We show that ASD is not only characterized by impairments in various neurocognitive domains, but also alterations in their interaction. PMID- 27696183 TI - Reduced Mimicry to Virtual Reality Avatars in Autism Spectrum Disorder. AB - Mimicry involves unconsciously copying the actions of others. Increasing evidence suggests that autistic people can copy the goal of an observed action but show differences in their mimicry. We investigated mimicry in autism spectrum disorder (ASD) within a two-dimensional virtual reality environment. Participants played an imitation game with a socially engaged avatar and socially disengaged avatar. Despite being told only to copy the goal of the observed action, autistic participants and matched neurotypical participants mimicked the kinematics of the avatars' movements. However, autistic participants mimicked less. Social engagement did not modulate mimicry in either group. The results demonstrate the feasibility of using virtual reality to induce mimicry and suggest mimicry differences in ASD may also occur when interacting with avatars. PMID- 27696184 TI - Perception of Life as Stressful, Not Biological Response to Stress, is Associated with Greater Social Disability in Adults with Autism Spectrum Disorder. AB - This study examined differences between adults with autism spectrum disorder (ASD; N = 40) and typical community volunteers (N = 25) on measures of stressful life events, perceived stress, and biological stress response (cardiovascular and cortisol reactivity) during a novel social stress task. Additional analyses examined the relationship between stress and social functioning as measured by the Social Adjustment Scale-II and the Waisman Activities of Daily Living scale. Results indicated that adults with ASD experienced significantly more stressful life events and perceived stress, and greater systolic blood pressure reactivity than typical community volunteers. Results also indicated that perceived stress and stressful life events were significantly associated with social disability. Interventions targeting stress management might improve social function in adults with ASD. PMID- 27696185 TI - Brief Report: Seeing the Man in the Moon: Do Children with Autism Perceive Pareidolic Faces? A Pilot Study. AB - Faces are one of the most socially significant visual stimuli encountered in the environment, whereas pareidolias are illusions of faces arising from ambiguous stimuli in the environment. Autism spectrum disorder (ASD) is characterised by deficits in response to social stimuli. We found that children with ASD (n = 60) identify significantly fewer pareidolic faces in a sequence of ambiguous stimuli than typically developing peers. The two groups did not differ in the number of objects identified, indicating that the children with ASD had a specific lack of attention to faces. Pareidolia have considerable potential as naturalistic and easy-to-create materials for the investigation of spontaneous attention to social stimuli in children with ASD. PMID- 27696186 TI - Anxiety Disorders in Williams Syndrome Contrasted with Intellectual Disability and the General Population: A Systematic Review and Meta-Analysis. AB - Individuals with specific genetic syndromes associated with intellectual disability (ID), such as Williams syndrome (WS), are at increased risk for developing anxiety disorders. A systematic literature review identified sixteen WS papers that could generate pooled prevalence estimates of anxiety disorders for WS. A meta-analysis compared these estimates with prevalence estimates for the heterogeneous ID population and the general population. Estimated rates of anxiety disorders in WS were high. WS individuals were four times more likely to experience anxiety than individuals with ID, and the risk was also heightened compared to the general population. The results provide further evidence of an unusual profile of high anxiety in WS. PMID- 27696187 TI - Reputation Management in Children on the Autism Spectrum. AB - Being able to manage reputation is an important social skill, but it is unclear whether autistic children can manage reputation. This study investigated whether 33 autistic children matched to 33 typical children could implicitly or explicitly manage reputation. Further, we examined whether cognitive processes theory of mind, social motivation, inhibitory control and reciprocity-contribute to reputation management. Results showed that neither group implicitly managed reputation, and there was no group difference in explicit reputation management. Results suggested different mechanisms contribute to reputation management in these groups-social motivation in typical children and reciprocity in autistic children. Explicit reputation management is achievable for autistic children, and there are individual differences in its relationship to underlying cognitive processes. PMID- 27696189 TI - Hyperuricemia, Hypertension, and Chronic Kidney Disease: an Emerging Association. AB - Uric acid is a product of purine metabolism and has been linked to gout and kidney calculi. Chronic kidney disease (CKD) and hypertension (HTN) are two major public health problems, and both are associated with increased risk of cardiovascular events. Emerging evidence suggests a pathogenic role of hyperuricemia in the development of HTN and CKD, in addition to progression of CKD, by inducing renal inflammation, endothelial dysfunction, and activation of the renin-angiotensin system. In addition, several epidemiological studies have linked hyperuricemia with an increased risk of HTN and CKD. A few clinical trials have assessed the use of uric acid-lowering therapies such as allopurinol and febuxostat in the management of HTN and delaying progression of CKD. To date, most of these trials are short-term with a small sample size; however, their results are encouraging and provide a rationale for larger randomized controlled trials to establish the role of uric acid-lowering therapies in the management of HTN, in addition to prevention of CKD progression and cardiovascular events. PMID- 27696190 TI - Successful management of perioperative hemostasis in a patient with Glanzmann thrombasthenia who underwent a right total mastectomy. AB - Perioperative hemostatic management is a challenge in patients with Glanzmann thrombasthenia (GT). The standard means of preventing surgical bleeding in GT patients is platelet transfusion. However, GT patients often possess alloantibodies against GPIIb/IIIa and/or HLA, which cause resistance to platelet transfusion. HLA-matched platelet transfusion, plasmapheresis, or recombinant human-activated factor VII (rFVIIa) are alternative interventions in such cases. Monitoring of hemostasis is also critical in the management of GT patients who undergo surgery. Here, we report the case of a 56-year-old female GT patient with anti-HLA antibodies, who underwent a right total mastectomy without significant blood loss under HLA-matched platelet transfusion. Bleeding at the surgical site, which occurred on the 18th postoperative day, was successfully treated by immediate bolus administration of rFVIIa and subsequent HLA-matched platelet transfusion. The perioperative hemostatic state was monitored in combination with bleeding time, platelet aggregation assay, and flow cytometric analysis of GPIIb/IIIa expression. Although a flow cytometric analysis is not a functional assay, it enabled the estimation of transfused platelet counts, and helped to inform the decision regarding whether to perform the surgery. Thus, perioperative hemostasis was successfully managed in our GT patient by HLA-matched platelet transfusion, rFVIIa administration, and the close monitoring of hemostasis. PMID- 27696191 TI - ADAMTS13: more than a regulator of thrombosis. AB - ADAMTS13, a plasma reprolysin-like metalloprotease, proteolyzes von Willebrand factor (VWF). ADAMTS13 is primarily synthesized by hepatic stellate cells (HSCs), and mainly regulates thrombogenesis by cleaving VWF. Recent studies demonstrate that ADAMTS13 also plays a role in the down-regulation of inflammation, regulation angiogenesis, and degradation of extracellular matrix. The purpose of this review is to introduce the state of progress with respect to some of the theorized roles of ADAMTS13. PMID- 27696192 TI - Fulminant type I diabetes mellitus associated with nivolumab in a patient with relapsed classical Hodgkin lymphoma. AB - We report the case of a patient with relapsed classical Hodgkin lymphoma who developed fulminant type I diabetes mellitus as a severe adverse event of treatment with the anti-programmed cell death-1 (PD-1) antibody, nivolumab. On the first day of the sixth cycle, the blood glucose level was markedly elevated (375 mg/dL). Although neither ketoacidosis nor ketonuria was detected, the markedly acute onset of the hyperglycemia was consistent with the typical clinical course of fulminant type I diabetes mellitus, and this diagnosis was supported by clinical data. All autoantibodies associated with type I diabetes mellitus were negative. The endogenous insulin secretion ceased completely within 2 weeks. After the blood glucose level was brought under control, nivolumab was resumed and continued without other major adverse events. Human leukocyte antigen (HLA) analysis revealed that the patient carried the HLA-B*4002 haplotype, a susceptibility allele for this type of diabetes mellitus. This case suggests that fulminant type I diabetes mellitus may be triggered by nivolumab in patients with a genetic background associated with the condition, warranting careful future consideration of this particular adverse event. PMID- 27696193 TI - Characterization, chemometric evaluation, and human health-related aspects of essential and toxic elements in Italian honey samples by inductively coupled plasma mass spectrometry. AB - Concentration values of 24 elements (Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, Ge, Hg, Mn, Mo, Pb, Sb, Se, Sn, Sr, Ti, Tl, U, V, and Zn) were determined in 72 honey samples produced in Italy by inductively coupled plasma mass spectrometry (ICP MS). Considering the recommended established heavy metal daily intakes for humans, in this perspective, an equilibrated and ordinary honey consumption should not be considered matter of concerns for human health, even if particular attention should be addressed if honey is consumed by children, due to different maximum daily heavy metal intakes. Chemometric analysis of the results obtained highlights heavy metal content differences in honey samples obtained from notoriously polluted zones, confirming then that honey can be considered a bio indicator of environmental pollution. Finally, Pearson coefficients highlighted correlations among element contents in honey samples. PMID- 27696194 TI - Advanced mortar coatings for cultural heritage protection. Durability towards prolonged UV and outdoor exposure. AB - In the present work, two kinds of hybrid polymeric-inorganic coatings containing TiO2 or SiO2 particles and prepared starting from two commercial resins (Alpha(r)SI30 and Bluesil(r)BP9710) were developed and applied to two kinds of mortars (an air-hardening calcic lime mortar [ALM] and a natural hydraulic lime mortar [HLM]) to achieve better performances in terms of water repellence and consequently damage resistance. The two pure commercial resins were also applied for comparison purposes. Properties of the coated materials and their performance were studied using different techniques such as contact angle measurements, capillary absorption test, mercury intrusion porosimetry, surface free energy, colorimetric measurements and water vapour permeability tests. Tests were also performed to determine the weathering effects on both the commercial and the hybrid coatings in order to study their durability. Thus, exposures to UV radiation, to UV radiation/condensed water cycles and to a real polluted atmospheric environment have been performed. The effectiveness of the hybrid SiO2 based coating was demonstrated, especially in the case of the HLM mortar. PMID- 27696196 TI - Effect of landfill cover layer modification on methane oxidation. AB - Levels of methane (CH4) oxidation in materials used for landfill cover attained in the laboratory are not often replicated in the field due to effects from the surrounding environment. This study investigates the three dominant factors affecting CH4 oxidation in the cover layer, namely, the thickness of cover layer, the methanotroph spraying manner, and the osmotic coefficient of the cover material. Results show that improved CH4 emission performance of the cover layer can be realized if methanotroph are introduced, meaning that a thinner cover layer is required. The highest CH4 emission reduction can be realized by spraying methanotroph into the top, middle, and bottom layers of a 30-cm thick cover layer with an osmotic coefficient of 7.76 * 10-5 cm s-1. Comparing results on cover layer thickness, methane monooxygenase (MMO) activity was much lower with increasing thickness meaning that the thicker cover could reduce O2 availability, thus inhibiting MMO activity. This suggests that MMO may be responsible for differences in CH4 emission reduction and/or oxidation making the osmotic coefficient an important factor for cover layer material. PMID- 27696195 TI - Measurement of p-nitrophenyl acetate esterase activity (EA), total antioxidant capacity (TAC), total oxidant status (TOS) and acetylcholinesterase (AChE) in gills and digestive gland of Mytilus galloprovincialis exposed to binary mixtures of Pb, Cd and Cu. AB - The aims of the present work were (1) to evaluate oxidative stress biomarkers and AChE in two tissues of wild mussel (Mytilus galloprovincialis) of high biochemical activity and accumulation capacity (gills and digestive gland) and (2) to study the behaviour of these biomarkers in presence of heavy metals. For this, EA, TOS, TAC and AChE were measured in tissues of mussels exposed to binary combination of Pb, Cd and Cu. Mussels (n = 36) were exposed to one of the binary mixtures of Pb (1000 MUg L-1), Cd (100 MUg L-1) and Cu (100 MUg L-1) for 7 days, under controlled conditions. Gills and digestive gland were extracted and frozen at -80 degrees C until analysis. The automatic methods employed for the measurement of EA, TAC, TOS and AChE in M. galloprovincialis revealed higher levels of these biomarkers in digestive gland than gills. Study results suggest that gills would be the tissue of election for study oxidative stress markers, whereas digestive tissue should be selected for AChE measurements in case of evaluation of combined metal toxicity in mussels. PMID- 27696197 TI - In vivo protective role against water contamination with cerium via chronic administration of omega 3. AB - In the present study, adult, healthy male Wistar rats (120 +/- 10 g) were pre treated by intragastric administration of cerium chloride (CeCl3) 10 mg/kg (BW) each day during 60 days. Control animal were treated with omega 3, a polyunsaturated fatty acid (omega-3), by an intragastric administration at 10 mg/kg of BW for 60 days. Our results showed that CeCl3-induced alterations in all tested oxidative stress markers. In fact, CeCl3-induced the increase the level of both the creatinine concentration and the expression of lactate dehydrogenase, alkaline phosphatase, and transaminase activities in serum. On the other hand, CeCl3 significantly increased the levels of lipid peroxidation in the renal and hepatic tissues. The capacity of CeCl3 to generate reactive oxygen species (ROS) could explain his ability to induce morphological alterations, such as centrilobular hemorrhage, hepatic necrosis, and vacuolization of the cytoplasm in hepatic tissues, and the atrophy of the glomerulus and dilatation of urinary space in renal tissues. However, omega 3, after gastric administration, reduced significantly the toxic effect caused by CeCl3 according to his high ability to scavenge ROS. The present study indicates that omega 3 is a significant compound with protective activity against intoxication with heavy metal, the cerium, and thus may be useful for chemoprevention. PMID- 27696198 TI - Thermodynamic study of seven micropollutants adsorption onto an activated carbon cloth: Van't Hoff method, calorimetry, and COSMO-RS simulations. AB - The thermodynamic of the adsorption of seven organic pollutants, namely benzotriazol, bisphenol A, caffeine, carbamazepine, diclofenac, ofloxacin, and pentachlorophenol, was studied on a microporous-activated carbon fabric. The isosteric adsorption quantities (Gibbs energy, enthalpy, and entropy variations) at high coverage ratio (around 1 mmol/g) have been determined from the adsorption isotherms at three temperatures (13, 25, and 40 degrees C). The adsorption heats at very low coverage (about 10-5 mmol/g) have been measured by flow micro calorimetry. The experimental adsorption energies were correlated to the adsorbate-adsorbent and the adsorbate-solvent interaction energies calculated by simulations using the COSMO-RS model. The main role of the van der Waals forces in the adsorption of the studied molecules was established. The bulkier the adsorbate is, the lower the adsorption Gibbs energy variation at high coverage deduced from the isotherms. The heterogeneity of the adsorption sites was brought out by calorimetric measurements. At high coverage, a physisorption phenomenon was observed. At very low coverage, high values of the adsorption heats were found (ranging from -58 to -110 kJ/mol), except for pentachlorophenol characterized by an athermal adsorption controlled by Pi-anions interactions. PMID- 27696199 TI - Mitigation of polar pesticides across a vegetative filter strip. A mesocosm study. AB - Vegetated filter strips (VFSs) are planted at the edge of agricultural fields to reduce pesticide run-off and its consequent potential toxicological effects on ecosystem biota; however, little attention has been paid to date to the attenuation of highly polar and ionisable pesticides such as phenoxyacid herbicides. This study assesses the effect of soil moisture, run-off flow and vegetation on the attenuation of MCPA, mecoprop, dicamba, dichlorprop, fenitrothion, atrazine and simazine by VFSs. Reactors measuring 5 m long by 0.1 m wide were each filled with 60 kg of soil from a real field VFS. VFSs planted with Phragmites australis and unvegetated control reactors were assessed. After a simulated rainfall event of 50 mm, two hydraulic loading rates (HLRs) were assessed (1 and 2 cm h-1). These results were compared to those from the same systems under water-saturated conditions. The results show that VFSs reduced the peak inlet concentration and pesticide mass by more than 90 % and that the presence of vegetation increased that attenuation (82-90 % without vegetation and 90-93 % with vegetation, on average). The laboratory-scale study showed that such attenuation was due to sorption into the soil. The toxicity units of pesticides fell by more than 90 % in all cases, except under the water-saturated conditions, in which the decrease was lower (16 vs 54 %, for unvegetated and vegetated reactors). Therefore, the presence of vegetation was shown to be effective for reducing mass discharge of ionisable and highly polar pesticides into surface water bodies. PMID- 27696200 TI - Distribution and sources of sterol biomarkers in sediments collected from a tropical estuary in Northeast Brazil. AB - The Piaui-Real estuary is located along the southern coast of Sergipe state, Northeast Brazil. This estuary has great economic importance due to its physical, biological, and socioeconomic diversity, but it is subject to anthropogenic stress since the resident population in the town bordered by the estuarine system has grown in recent years. Thus, the possibility of sewage contamination originating from the approximately 450,000 inhabitants living within its drainage basin was investigated in this study. Sediment samples were collected from 15 sampling stations along the estuarine system and extracted, followed by gas chromatography-mass spectrometry (GC-MS) analysis. Six sterols were quantified, indicating natural and anthropogenic sources. Coprostanol concentrations higher than 100 ng g-1 were observed in 47 % of the stations analyzed, indicating sewage contamination, which was confirmed by the diagnostic ratios calculated. Based on the Pearson correlation test, a significant correlation between coprostanol concentrations and total organic carbon content (TOC) was observed, indicating that sterols record the history of sewage inputs in this area. These results indicate that control of the organic inputs into the estuarine system is required. Graphical abstract Sterol markers were determined and sources assessed in surface sediments from Piaui-Real estuarine system. PMID- 27696201 TI - Isolated Cardiac Richter Syndrome: a Case Report. PMID- 27696202 TI - Expression of programmed cell death 1 and programmed cell death ligand 1 in extranodal NK/T-cell lymphoma, nasal type. AB - Programmed cell death-1 (PD-1) and programmed cell death-ligand 1 (PD-L1) are new therapeutic targets in cancer immunotherapy. The aim of this study was to investigate the clinicopathological characteristics of PD-1 and PD-L1 expression in extranodal natural killer/T-cell lymphoma, nasal type (ENKTL). We performed PD 1 and PD-L1 immunostaining in 79 ENKTL biopsy samples and retrospectively analyzed medical records of all 79 patients from four tertiary referral hospitals. The expression of PD-1 and PD-L1 by tumor cells and/or infiltrating immune cells was evaluated. The expression rates of PD-L1 in tumor cells and infiltrating immune cells were 79.7 and 78.5 %, respectively, whereas PD-1 in tumor cells and infiltrating immune cells were 1.3 and 11.4 %. The PD-L1 positivity in tumor cells and infiltrating immune cells was significantly associated with low international prognostic index (IPI) (P = 0.044 and 0.037, respectively). Patients with normal range of serum lactate dehydrogenase demonstrated a significantly higher PD-L1 positivity in tumor cells (P = 0.020). PD-L1-positive patients had a trend toward better overall survival compared with that in patients with PD-L1-negative in tumor cells and infiltrating immune cells (P = 0.498 and 0.435, respectively). The expression rate of PD-L1 was up to 79.7 % in ENKTL, while PD-1 expression rate was very low. This is the first report describing the clinicopathological features and survival outcome according to expression of PD-1 and PD-L1 in ENKTL.

PMID- 27696203 TI - All-trans retinoic acid as adjunct to intensive treatment in younger adult patients with acute myeloid leukemia: results of the randomized AMLSG 07-04 study. AB - The aim of this clinical trial was to evaluate the impact of all-trans retinoic acid (ATRA) in combination with chemotherapy and to assess the NPM1 status as biomarker for ATRA therapy in younger adult patients (18-60 years) with acute myeloid leukemia (AML). Patients were randomized for intensive chemotherapy with or without open-label ATRA (45 mg/m2, days 6-8; 15 mg/m2, days 9-21). Two cycles of induction therapy were followed by risk-adapted consolidation with high-dose cytarabine or allogeneic hematopoietic cell transplantation. Due to the open label character of the study, analysis was performed on an intention-to-treat (ITT) and a per-protocol (PP) basis. One thousand one hundred patients were randomized (556, STANDARD; 544, ATRA) with 38 patients treated vice versa. Median follow-up for survival was 5.2 years. ITT analyses revealed no difference between ATRA and STANDARD for the total cohort and for the subset of NPM1-mutated AML with respect to event-free (EFS; p = 0.93, p = 0.17) and overall survival (OS; p = 0.24 and p = 0.32, respectively). Pre-specified PP analyses revealed better EFS in NPM1-mutated AML (p = 0.05) and better OS in the total cohort (p = 0.03). Explorative subgroup analyses on an ITT basis revealed better OS (p = 0.05) in ATRA for genetic low-risk patients according to ELN recommendations. The clinical trial is registered at clinicaltrialsregister.eu (EudraCT Number: 2004-004321 95). PMID- 27696205 TI - Gastric plexiform schwannoma in association with neurofibromatosis type 2. AB - : Plexiform schwannoma (PS) is an uncommon variant of schwannoma characterized by a multinodular (plexiform) growth pattern. It comprises up to 5 % of all schwannomas. The association between PS and neurofibromatosis type 1 or type 2 (NF1/NF2) is only rarely reported. Most cases of PS occur in the skin and subcutaneous soft tissue, with only a few reports of digestive tract involvement. We describe an 18-year-old male with NF2 who had bilateral vestibular schwannomas and multiple cutaneous PSs, and a 3-year history of abdominal pain. The patient ultimately underwent a distal gastrectomy for a partially obstructing submucosal antral mass, associated with an overlying ulcer. Histopathologic examination showed the mass to be a PS. The patient is alive and well, without symptoms, 12 months postoperatively. A review of the English language medical literature yielded only ten examples of PS arising in the digestive tract. Our patient is the first to be reported to have a gastric PS, and only the second patient to be reported with a digestive tract PS to have NF2, and the only patient reported to have both digestive tract and cutaneous PSs. Despite its rare occurrence with NF2, the finding of PS at any site should stimulate an examination for other manifestations of this disorder. CLINICAL TRIAL REGISTRATION: None. PMID- 27696206 TI - Molecular Recognition of Azelaic Acid and Related Molecules with DNA Polymerase I Investigated by Molecular Modeling Calculations. AB - Molecular recognition has central role on the development of rational drug design. Binding affinity and interactions are two key components which aid to understand the molecular recognition in drug-receptor complex and crucial for structure-based drug design in medicinal chemistry. Herein, we report the binding affinity and the nonbonding interactions of azelaic acid and related compounds with the receptor DNA polymerase I (2KFN). Quantum mechanical calculation was employed to optimize the modified drugs using B3LYP/6-31G(d,p) level of theory. Charge distribution, dipole moment and thermodynamic properties such as electronic energy, enthalpy and free energy of these optimized drugs are also explored to evaluate how modifications impact the drug properties. Molecular docking calculation was performed to evaluate the binding affinity and nonbonding interactions between designed molecules and the receptor protein. We notice that all modified drugs are thermodynamically more stable and some of them are more chemically reactive than the unmodified drug. Promise in enhancing hydrogen bonds is found in case of fluorine-directed modifications as well as in the addition of trifluoroacetyl group. Fluorine participates in forming fluorine bonds and also stimulates alkyl, pi-alkyl interactions in some drugs. Designed drugs revealed increased binding affinity toward 2KFN. A1, A2 and A3 showed binding affinities of -8.7, -8.6 and -7.9 kcal/mol, respectively against 2KFN compared to the binding affinity -6.7 kcal/mol of the parent drug. Significant interactions observed between the drugs and Thr358 and Asp355 residues of 2KFN. Moreover, designed drugs demonstrated improved pharmacokinetic properties. This study disclosed that 9-octadecenoic acid and drugs containing trifluoroacetyl and trifluoromethyl groups are the best 2KFN inhibitors. Overall, these results can be useful for the design of new potential candidates against DNA polymerase I. PMID- 27696207 TI - Bioactivity of Marine Streptomyces sp. VITJS4: Interactions of Cytotoxic Phthalate Derivatives with Human Topoisomerase II alpha: An In Silico Molecular Docking Analysis. AB - Despite clinical advances in antimicrobial and anticancer therapy, there is an urge for the search of new bioactive compounds. In the present study, previously isolated Streptomyces sp. VITJS4 strain (NCIM No. 5574) (ACC No: JQ234978.1) crude extract tested for antibacterial activity showed a broad spectrum at the concentration of 20 mg/mL against pathogens. The antioxidant potential tested at 0.5 mg/mL concentration exhibited reducing power activity with a maximum of 90 % inhibition. The anticancer property by MTT assay on HeLa and HepG2 cells showed cytotoxic effect with IC50 of 50 ug/mL each. The DNA fragmentation pattern observed in both HeLa and HepG2 cell indicated laddering pattern at 40 ug/mL concentration. GC-MS analysis revealed that the significant peak corresponding at m/z 149 (M+) was identified as phthalate derivatives. The extract was further separated by HPLC with their retention times (t r) at 6.294 min. The above obtained results were also supported by molecular docking studies which provide an insight into ligand binding to the active site of the receptor. The in silico docking studies revealed better binding affinity with a binding energy of -5.87 kJ mol-1 of the ligand toward topoisomerase II alpha. PMID- 27696208 TI - Structure-Based Drug Designing and Simulation Studies for Finding Novel Inhibitors of Heat Shock Protein (HSP70) as Suppressors for Psoriasis. AB - Psoriasis is a chronic immune-mediated inflammatory skin disorder. Heat shock proteins (HSPs) have been witnessed as a potential drug target for inhibition of psoriatic cell differentiation. The expression level of HSP is increased when the cells get exposed to elevated temperature, oxidative stress and nutritional deficiencies and thus plays major role in psoriatic progression pathway. Immunoreactivity intensity distribution index scores for HSP70 expression is significantly higher in psoriatic patients compared to normal. In the present work, the 3D structure of human Hsp70 has been taken. Inhibition of HSP70 can control the severity of psoriasis up to many folds; thus, virtual screening was performed against lead-like, drug-like and some natural product of ZINC database. The screened ligands were further introduced to ADMET prediction and simulations to see the drug proficiency and likeness property. The molecular dynamic of system was found stable during simulation trajectory and not much of significant changes occurred in the conformation of the protein-ligand complex. Thus, present study in all probability might prove useful for future design of new derivatives with higher potency and specificity. PMID- 27696209 TI - Impact of Delta Hemoglobin on Provider Transfusion Practices and Post-operative Morbidity Among Patients Undergoing Liver and Pancreatic Surgery. AB - BACKGROUND: Delta hemoglobin (DeltaHb) is defined as the difference between the preoperative Hb and the lowest post-operative Hb level. We sought to define the impact of DeltaHb relative to nadir Hb levels on the likelihood of transfusion, as well as characterize the impact of DeltaHb and nadir Hb on morbidity among a large cohort of patients undergoing complex hepatopancreatobiliary (HPB) surgery. METHODS: Patients who underwent pancreatic or hepatic resection between January 1, 2009 and June 30, 2015 at Johns Hopkins Hospital were identified. Data on the perioperative DeltaHb, nadir Hb, as well as blood utilization were obtained and analyzed. Multivariable logistic regression models were used to identify the factors associated with DeltaHb and the impact of DeltaHb on perioperative morbidity. A Bayesian model was used to evaluate the correlation of DeltaHb and nadir Hb with the likelihood of transfusion, as well as the impact on morbidity. RESULTS: A total of 4363 patients who underwent hepatobiliary (n = 2200, 50.4 %) or pancreatic (n = 2163, 49.6 %) surgery were identified. More than one quarter of patients received at least one unit of packed red blood cells (PRBC) (n = 1187, 27.2 %). The median nadir Hb was 9.2 (IQR 7.9-10.5) g/dL resulting in an average DeltaHb of 3.4 mg/dL (IQR 2.2-4.7) corresponding to 26.3 %. Both DeltaHb and nadir Hb strongly influenced provider behavior with regards to use of transfusion. Among patients with the same nadir Hb, DeltaHb was strongly associated with use of transfusion; among patients who had a nadir Hb <=6 g/dL, the use of transfusion was only 17.9 % when the DeltaHb = 10 % versus 49.1 and 80.9 % when the DeltaHb was 30 or 50 %, respectively. Perioperative complications occurred in 584 patients (13.4 %) and were more common among patients with a higher value of DeltaHb, as well as patients who received PRBC (both P < 0.001). CONCLUSIONS: The combination of the Hb trigger with DeltaHb was associated with transfusion practices among providers. Larger DeltaHb values, as well as receipt of transfusion, were strongly associated with risk of perioperative complication following HPB surgery. PMID- 27696210 TI - Investigation of noise sources for digital radiography systems. AB - The performance of digital radiography systems can be evaluated in terms of spatial resolution and noise. Noise plays an important role in the achievable image quality for detecting small and low-contrast structures in digital images created by these systems. Our aim in this study was to investigate the noise sources both in the spatial and frequency domain for three digital radiography systems, one digital fluoroscopy system, and one digital mammography system, and to obtain information about the effective operating dose range of these detectors. Noise evaluation in the spatial domain was done with the relative standard deviation-detector air kerma relationship evaluation method. The characterization of the noise in the spatial domain gives information about the types of noise, but does not give information about the noise power distribution in frequency space. Therefore, noise evaluation in the frequency domain was carried out by noise power spectrum measurement. The observed dominant noise component at lower detector doses was electronic noise for the digital mammography system, whereas structured noise was observed to make up nearly half of the total noise at higher detector doses for one of the digital radiography systems. The structured noise component was increased by use of a grid in these systems, independent of the grid ratio and grid frequency, but this increase was lower for higher grid frequencies. Furthermore, the structured noise coefficient was decreased with gain and offset calibrations. The five systems which we evaluated behaved as a quantum noise limited for clinically used detector doses. PMID- 27696211 TI - The Myocyte-Damaging Effects of the BCR-ABL1-Targeted Tyrosine Kinase Inhibitors Increase with Potency and Decrease with Specificity. AB - Five clinically approved BCR-ABL1-targeted tyrosine kinase inhibitors (bosutinib, dasatinib, imatinib, nilotinib, and ponatinib) used for treating chronic myelogenous leukemia have been studied in a neonatal rat myocyte model for their relative ability to induce myocyte damage. This was done in order to determine if kinase inhibitor-induced myocyte damage was a consequence of inhibiting ABL1 (on target effects), or due to a lack of kinase selectivity (off-target effects) since previous studies have come up with conflicting conclusions about whether imatinib-induced cardiotoxicity results directly from inhibition of ABL1. The most specific and least potent inhibitors, imatinib and nilotinib, induced the least myocyte damage, while the least specific and most potent inhibitors, ponatinib and dasatinib, induced the most damage. Inhibitor-induced myocyte damage also correlated with clinically observed cardiovascular toxicity. Growth inhibition of the erythroleukemic K562 human cell line with a constitutively active BCR-ABL1 kinase was negatively correlated with inhibitor-induced myocyte damage, which suggests that inhibition of ABL1 causes myocyte damage. Myocyte damage was also negatively correlated with inhibitor dissociation binding constants and with inhibition of enzymatic ABL1 kinase activity. Myocyte damage was also positively correlated with two measures of inhibitor selectivity, which suggests that a lack of inhibitor selectivity is responsible for myocyte damage. In conclusion, myocyte damage, and thus the cardiovascular toxicity of the BCR ABL1-targeted tyrosine kinase inhibitors, is due to direct inhibition of ABL1 and/or their lack of inhibitor selectivity. PMID- 27696212 TI - Neonatal gastrointestinal perforation in Japan: a nationwide survey. AB - PURPOSE: The purpose of this study is to identify the current clinical features of neonatal gastrointestinal perforation in Japan. METHODS: A questionnaire about cases of neonatal gastrointestinal perforation treated in recent 5 years was sent to participating institutions of the Japanese Society of Pediatric Surgeons (JSPS). RESULTS: Five hundred and thirty-six neonates with gastrointestinal perforation were treated. They consisted of 42 patients with gastric rupture/perforation (GR), 33 patients with intestinal atresia/stenosis (IA), 3 patients with malrotation (ML), 118 patients with necrotizing enterocolitis (NEC), 160 patients with focal intestinal perforation (FIP), 46 patients with meconium-related ileus (MRI), 77 patients with meconium peritonitis (MP), and 57 patients with other conditions. The total mortality rate was 20.5 %. The mortality rates of the patients with GR, IA, ML, NEC, FIP, MRI, and MP were 9.5, 9.1, 0, 33.1, 20.6, 28.2, and 9.1 %, respectively. In 263 cases involving extremely low-birth-weight neonates (ELBW), 108 died (mortality rate 41.1 %). The mortality rates for ELBW with GR, NEC, FIP, MRI, MP, and other conditions were 27.3 % (3/11), 58.5 % (48/82), 21.6 % (24/111), 70.6 % (24/34), 57.1 % (4/7), and 27.8 % (5/18), respectively. CONCLUSIONS: The mortality rates for ELBW decreased from 62.8 % in the previous survey to 41.1 % by the time of this survey. PMID- 27696213 TI - Primary spontaneous mesencephalic hemorrhage. PMID- 27696214 TI - Socioeconomic status is associated with urinary diversion utilization after radical cystectomy for bladder cancer. AB - PURPOSE: To assess socioeconomic disparities in urinary diversion utilization in a contemporary American cohort. METHODS: In the National Cancer Database, we identified 4538 patients who underwent cystectomy with urinary diversion for clinical T1-2N0M0 bladder cancer from 2010 to 2013. Multivariable logistic regression was used to identify predictors of urinary diversion type: ileal conduit (IC), continent cutaneous reservoir (CCR), or orthotopic neobladder (ON). Covariates included age, gender, race, income, Charlson score, clinical T stage, hospital cystectomy volume, teaching status, and surgical approach. Subgroup analysis by hospital volume (low, intermediate, or high) and teaching status (academic or non-academic) was performed to ascertain the impact of regionalization on urinary diversion use. RESULTS: The final cohort included 4066 (89.6 %) patients with IC, 292 (6.4 %) with CCR, and 180 (4.0 %) with ON. On multivariable analysis, younger age (p < .01), higher income (p < .01), and high cystectomy volume predicted increased use of CCR and ON. Female gender predicted increased use of CCR versus IC (p < .01), and academic hospital status predicted increased use of ON versus IC (p = .04). On subgroup analysis, after further adjustment for hospital volume and teaching status, higher income remained an independent predictor of ON use. CONCLUSIONS: Despite regionalization of care, higher income patients are more likely to receive complex urinary diversions after radical cystectomy. Other related socioeconomic factors, especially patient education, may influence this practice pattern. PMID- 27696215 TI - Employment of Near Full-Length Ribosome Gene TA-Cloning and Primer-Blast to Detect Multiple Species in a Natural Complex Microbial Community Using Species Specific Primers Designed with Their Genome Sequences. AB - It remains an unsolved problem to quantify a natural microbial community by rapidly and conveniently measuring multiple species with functional significance. Most widely used high throughput next-generation sequencing methods can only generate information mainly for genus-level taxonomic identification and quantification, and detection of multiple species in a complex microbial community is still heavily dependent on approaches based on near full-length ribosome RNA gene or genome sequence information. In this study, we used near full-length rRNA gene library sequencing plus Primer-Blast to design species specific primers based on whole microbial genome sequences. The primers were intended to be specific at the species level within relevant microbial communities, i.e., a defined genomics background. The primers were tested with samples collected from the Daqu (also called fermentation starters) and pit mud of a traditional Chinese liquor production plant. Sixteen pairs of primers were found to be suitable for identification of individual species. Among them, seven pairs were chosen to measure the abundance of microbial species through quantitative PCR. The combination of near full-length ribosome RNA gene library sequencing and Primer-Blast may represent a broadly useful protocol to quantify multiple species in complex microbial population samples with species-specific primers. PMID- 27696216 TI - Correlates of Condom Use and Procedure Knowledge Among Men Accessing Voluntary Medical Male Circumcision in Malawi. AB - PURPOSE: This study examined correlates of condom use (CU) and voluntary medical male circumcision (VMMC) knowledge among men accessing VMMC services in Malawi. METHODS: Two hundred sixty-nine men ages 16 or older accessing VMMC were recruited at service sites. Bivariate and multivariate logistic regressions were used to determine associations, and the relative odds of CU at last sex with VMMC knowledge. Correlates included the following: education, age, location, religion, marital status, ever tested for HIV, having casual/concurrent sexual partners, and alcohol use before sex. RESULTS: The multivariate analysis revealed CU was associated with having a casual/concurrent partner in the previous 3 months and negatively associated with being age 27 or older and single, with participants who had casual/concurrent partners being more likely to use condoms than counterparts who did not have casual/concurrent partners, and those who were over age 27 and single being less likely to do so. VMMC knowledge was associated with education and location, with men with higher education and living in urban areas more likely to know that VMMC partially protects against HIV. CONCLUSION: Results highlight the need to ensure information about VMMC is appropriate for rural men with lower education. Further research is needed to understand the risk profile of men accessing VMMC and the reasons why men who do not know VMMC partially protects against HIV are seeking the service. PMID- 27696217 TI - Decoding the Structure of Abuse Potential for New Psychoactive Substances: Structure-Activity Relationships for Abuse-Related Effects of 4-Substituted Methcathinone Analogs. AB - Many cathinone analogs act as substrates or inhibitors at dopamine, norepinephrine, and serotonin transporters (DAT, NET, SERT, respectively). Drug selectivity at DAT vs. SERT is a key determinant of abuse potential for monoamine transporter substrates and inhibitors, such that potency at DAT > SERT is associated with high abuse potential, whereas potency at DAT < SERT is associated with low abuse potential. Quantitative structure-activity relationship (QSAR) studies with a series of 4-substituted methcathinone analogs identified volume of the 4-position substituent on the methcathinone phenyl ring as one structural determinant of both DAT vs. SERT selectivity and abuse-related behavioral effects in an intracranial self-stimulation procedure in rats. Subsequent modeling studies implicated specific amino acids in DAT and SERT that might interact with 4-substituent volume to determine effects produced by this series of cathinone analogs. These studies illustrate use of QSAR analysis to investigate pharmacology of cathinones and function of monoamine transporters. PMID- 27696218 TI - Analgesic Drug Prescription Patterns on Five International Paediatric Wards. AB - AIM: Analgesic and anti-inflammatory drugs are frequently prescribed in paediatrics. Prescribing and dosing patterns in hospitalised children are not well known. This study explores analgesic drug utilisation on five paediatric wards and discusses its findings in comparison with World Health Organization (WHO) guidelines. METHOD: A sub-analysis of a prospective, multicentre, observational cohort study was undertaken. Prescription data of children aged up to <=18 years were collected between October 2008 and December 2009 on paediatric general medical wards in five hospitals in Australia, Germany, the United Kingdom (UK), Hong Kong (HK) and Malaysia. Analgesic drug prescriptions were analysed for prescribing patterns in terms of dosing, frequency and route of administration. Dosing data were compared with local recommendations and WHO guidelines for children. RESULTS: In the study cohort, 56.8 % (726/1278) of paediatric patients received at least one analgesic drug prescription (1227 prescriptions). The median age of patients with analgesics was 2.2 years [interquartile range (IQR) 0.8-7.3], and the median number of prescriptions per patient was one (IQR 1-2). The most commonly prescribed drugs were oral paracetamol (45.9 %, 563/1227) and oral ibuprofen (19.9 %, 244/1227). Daily doses of paracetamol ranged from 30 mg/kg/day in Germany to 67-68 mg/kg/day in the UK and HK (p < 0.05). For ibuprofen, single doses ranged from 5-6 mg/kg in HK and the UK to 10 mg/kg in Germany and Australia (p < 0.001). Opioid use prevalence was statistically different between the centres and ranged from 0 to 17.6 % (p < 0.001). CONCLUSION: This study provides a comprehensive overview of analgesic drug use of hospitalised children. Similar to primary care data, paracetamol is the most commonly used analgesic. As recommended by WHO guidelines, oral medication was favoured and opioids used in addition to paracetamol and ibuprofen. Overall drug utilisation was in line with local recommendations and WHO guidelines. Differences in use of paracetamol and ibuprofen among countries were seen, indicating that safety concerns are perceived differently. More large-scale safety studies are needed. PMID- 27696219 TI - A mixed methods study of ruminant brucellosis in central-eastern Tunisia. AB - In this study, we conducted an investigation to determine the true prevalence of bovine and ovine brucellosis in central-eastern Tunisia. A total of 1134 veterinary samples taken from 130 ruminant herds were screened for brucellosis using IS711-based real-time PCR assay. Sera collected from the ruminants were tested using the Rose Bengal test and indirect enzyme-linked immunosorbent assay. Based on serological and molecular results, the true adjusted animal population level prevalence was 23.5 % in cattle, against 13.5 % in sheep. In addition, the true adjusted herd level prevalence of brucellosis was 55.6 % in cattle and 21.8 % in sheep. A statistically significant association was found between vaginal and milk shedding for ruminants. In addition, our results showed that Brucella abortus could be responsible for bovine and ovine brucellosis. Multivariable logistic regression analysis at the animal population level indicated that age and origin variables were important risk factors for cattle. However, age and abortion variables were found to be associated with ovine brucellosis. At the herd level, risk factors for Brucella positivity were as follows: abortion and herd composition for cattle against herd composition, mortality rates, and hygiene for sheep. Animal hygiene, food quality, and sanitary practices on the farm should be applied as strategies to control brucellosis in herds. PMID- 27696220 TI - Population Pharmacokinetics of Necitumumab in Cancer Patients. AB - Necitumumab is a second-generation, recombinant, human immunoglobulin G1, epidermal growth factor (EGFR) receptor antibody that specifically blocks the ligand binding site of EGFR. Necitumumab potentially acts by blocking ligand epidermal growth factor (EGF) binding-mediated activation of the EGFR signaling pathway, inhibiting tumor growth, angiogenesis, and anti-apoptotic mechanisms. Necitumumab inhibited the interaction of EGF and EGFR with a concentration that inhibits binding by 50 % of approximately 0.9 nM (0.13 mg/L) and demonstrated antitumor activity during in vivo experiments associated with trough plasma concentrations of approximately 40 mg/L. This work describes the population pharmacokinetics of necitumumab in cancer patients when administered with or without concomitant chemotherapy and evaluates patient characteristics that may guide dosing. Nonlinear mixed-effects modeling of serum concentration data across five clinical studies (phases I-III) indicated that necitumumab exhibited target mediated drug disposition, commonly observed with monoclonal antibodies, and that pharmacokinetics were expected to be linear in the studied dose ranges when administered as repeated infusions. No age, sex, race, or concomitant medication factors were found influential, while weight was a statistically significant factor for both distribution and elimination. Simulations from the final model indicated that only a limited reduction in patient drug exposure variability would be achieved by weight- or body surface area-based dosing. Necitumumab effective half-life was estimated to approximately 2 weeks, and steady state was achieved within three to four cycles of treatment. The phase III dosing schedule of 800 mg dosed on days 1 and 8 of a 21-day schedule resulted in serum concentrations that exceeded the 40-mg/L threshold indicated by preclinical experiments. PMID- 27696221 TI - A Review of Insulin Degludec/Insulin Aspart: Pharmacokinetic and Pharmacodynamic Properties and Their Implications in Clinical Use. AB - Insulin degludec/insulin aspart (IDegAsp; 70 % IDeg and 30 % IAsp) is a soluble combination of two individual insulin analogues in one product, designed to provide mealtime glycaemic control due to the IAsp component and basal glucose lowering effect from the IDeg component. The pharmacokinetic and pharmacodynamic characteristics of IDegAsp have been investigated in a series of clinical pharmacology studies with generally comparable designs, methodologies and patient inclusion/exclusion criteria. The glucose-lowering effect profile of IDegAsp during once-daily dosing at steady state shows distinct and clearly separated action from the prandial and basal components of IDegAsp. The IAsp component provides rapid onset and peak glucose-lowering effect followed by a flat glucose lowering effect lasting beyond 30 h due to IDeg. During twice-daily dosing, the distinct peak effect and the flat basal effect are retained following each dose. The pharmacological properties of IDegAsp are maintained in the elderly, children, adolescents, Japanese patients and those with hepatic or renal impairment. The potential clinical benefits associated with the pharmacological properties of IDegAsp have been verified in phase III clinical trials comparing IDegAsp with three other currently available treatment options: premixed insulin, basal-bolus regimens and basal-only therapy. IDegAsp shows favourable clinical benefits compared with biphasic insulin aspart 30 and is a viable alternative to basal-bolus and basal-only therapy. This review presents the results from clinical pharmacology studies conducted with IDegAsp to date, and extrapolates these results to clinical use of IDegAsp in the context of findings from the IDegAsp clinical therapeutic studies. PMID- 27696222 TI - Gene Expression Profiling Stratifies IDH1-Mutant Glioma with Distinct Prognoses. AB - Isocitrate dehydrogenase (IDH)1 mutation is one of the most important genetic aberrations in glioma. Even several genetic events have refined its prognostic value, the genome-wide expression alteration has not been systematically profiled. In this work, RNA-seq expression data from 310 patients in the Chinese Glioma Genome Atlas database were included as training set, while another 297 patients with microarray data were used as internal validation set. An independent cohort of GSE16011 (n = 205) constituted an external validation set. Approximately one fifth of the genes were differentially expressed in LGG according to IDH1 mutation status, yielding distinct gene expression profiles. A six-gene risk signature was established for IDH1-mutant LGG to distinguish low- from high-risk cases, which had distinct prognoses. The six-gene signature was an independent prognostic factor for IDH1-mutant LGG and had superior predictive value as compared to traditional clinicopathologic factors. Moreover, we depicted the differential expression pattern in GBM attributing to various IDH1 status, which was similar to that of LGG. It suggested that the effect of IDH1 mutation is conserved across histological classifications. The six-gene signature had equal prognostic value for IDH1-mutant GBM. By combining glioma grade, IDH1 status, and the six-gene signature, all glioma patients could be classified into six subgroups. These six subgroups could be further summarized into three sets with distinct prognosis. Taken together, a gene expression profile associated with IDH1 status was identified in LGG and GBM; a risk signature based on six genes was developed with equal prognostic value for IDH1-mutant LGG and GBM. When combined with clinicopathologic factors, the six-gene signature is a tool that enables precise risk stratification and can improve clinical management. PMID- 27696224 TI - Cyanidation of Mercury-Contaminated Tailings: Potential Health Effects and Environmental Justice. AB - There is a variety of health and environmental issues associated with artisanal and small-scale gold mining (ASGM), which includes concerns regarding mercury pollution. In many countries, intervention programs and policies emphasized the importance of reducing mercury use by focusing on viable alternative methods to amalgamation that may include a transition to cyanidation. ASGM communities that now employ a combination of both methods may be increasing health and environmental risks by using mercury-contaminated tailings in the cyanidation process. This review provides a current overview of mercury and cyanide use in ASGM including the dangers of centralized processing centers that lack best practices. The combination of amalgamation and cyanidation has the potential to adversely affect many ASGM communities around the world and necessitates additional investigations to determine environmental and health impacts. PMID- 27696223 TI - Nrf2-a Promising Therapeutic Target for Defensing Against Oxidative Stress in Stroke. AB - Stroke is one of the leading causes of death and disability in the world. Oxidative stress, which refers to an excessive generation of reactive oxygen species (ROS), plays a key role in the pathological process of stroke. Excessive ROS production contributes to brain ischemia/reperfusion injury through many mechanisms including BBB disruption, inflammation, apoptosis, and cellular necrosis. Nuclear factor-E2-related factor 2 (Nrf2) is one of the critical regulators of endogenous antioxidant defense, which promote the transcription of a wide variety of antioxidant genes. Emerging evidence has demonstrated that activation of Nrf2 and its target genes may protect the brain against ischemia/reperfusion injury, and therapies aimed at increasing Nrf2 activity appear to be beneficial to alleviate brain injury in stroke through the suppression of oxidative stress. The main purpose of this review is to discuss the current evidence for the role of Nrf2 in stroke and the potential interventions to enhance Nrf2 activation to attenuate stroke-induced injury.

It is a multi-factorial disease with epigenetic factors being also involved in its development. FAT4 is a tumor suppressor gene exerting an important role in cell adhesion. This study aimed at analyzing FAT4 expression and promoter methylation in gastric cancer. FAT4 expression was studied in 30 tumoral tissues and their non-tumoral counterparts using Taqman real time PCR method. Promoter methylation was assessed using bisulfite conversion method followed by sequencing. Tumor tissues showed reduced FAT4 expression (P = 0.04). FAT4 downregulation was associated with tumor grade, with higher repression at advanced grades. Significant increase of promoter methylation was observed in tumoral tissues. Reduced expression of FAT4 and increased methylation of its promoter may be one of the effective processes in turning a healthy stomach tissue into a tumor tissue.

AB - Toxoplasma (T.) gondii is able to infect various cell types in different hosts. The replication of this parasite within different peripheral mononuclear blood cell populations in chicken has not yet been fully understood. Aim of the present study was to investigate the impact of chicken erythrocytes and thrombocytes as potential host cells for T. gondii. Cultures of primary avian erythrocytes and thrombocytes were inoculated with tachyzoites of T. gondii type II strain ME49. Parasite replication was detected by a quantitative real-time PCR at different times postinoculation until 24 or 48 h, respectively, displaying long-term investigations for the chosen cultures. The parasite replication curve showed a continuous decrease of parasite stages in erythrocytes and thrombocytes. Observations by light microscopy showed massive destruction for both cell populations. Few macrophages in between the infected thrombocytes were viable during the investigation period and showed internalised tachyzoites by confocal laser scanning microscopy. These findings show that T. gondii is not capable of replication in chicken erythrocytes and thrombocytes; therefore, both cannot be considered as potential host cells. In further consequence, monocyte-derived macrophages seem to be the key to the dissemination mechanisms for T. gondii in chicken. PMID- 27696225 TI - Recent Scientific Evidence Regarding Asbestos Use and Health Consequences of Asbestos Exposure. AB - To justify the continuous use of two million tons of asbestos every year, it has been argued that a safe/controlled use can be achieved. The aim of this review was to identify recent scientific studies that present empirical evidence of: 1) health consequences resulting from past asbestos exposures and 2) current asbestos exposures resulting from asbestos use. Articles with evidence that could support or reject the safe/controlled use argument were also identified. A total of 155 articles were included in the review, and 87 % showed adverse asbestos health consequences or high asbestos exposures. Regarding the safe/controlled use, 44 articles were identified, and 82 % had evidence suggesting that the safe/controlled use is not being achieved. A large percentage of articles with evidence that support the safe/controlled use argument have a conflict of interest declared. Most of the evidence was developed in high-income countries and in countries that have already banned asbestos. PMID- 27696228 TI - Biomarkers indicate mixture toxicities of fluorene and phenanthrene with endosulfan toward earthworm (Eisenia fetida). AB - alpha-Endosulfan and some polycyclic aromatic compounds (PAHs) are persistent in the environment and can reach crop products via contaminated agricultural soils. They may even be present as mixtures in the soil and induce mixture toxicity in soil organisms such as earthworms. In this study, the combined toxicities of PAHs with alpha-endosulfan were determined in Eisenia fetida adults using an artificial soil system. alpha-Endosulfan and five PAHs were tested for their acute toxicity toward E. fetida in artificial soils. Only alpha-endosulfan, fluorene, and phenanthrene showed acute toxicities, with LC50 values of 9.7, 133.2, and 86.2 mg kg-1, respectively. A mixture toxicity assay was conducted using alpha-endosulfan at LC10 and fluorene or phenanthrene at LC50 in the artificial soils. Upon exposure to the mixture of fluorene and alpha-endosulfan, earthworms were killed in increasing numbers owing to their synergistic effects, while no other mixture showed any additional toxicity toward the earthworms. Along with the acute toxicity results, the biochemical and molecular changes in the fluorene- and phenanthrene-treated earthworms with or without alpha endosulfan treatment demonstrated that enhancement of glutathione S-transferase activity was dependent on the addition of PAH chemicals, and the HSP70 gene expression increased with the addition of alpha-endosulfan. Taken together, these findings contribute toward understanding the adverse effects of pollutants when present separately or in combination with other types of chemicals. PMID- 27696229 TI - Radon levels in Romanian caves: an occupational exposure survey. AB - A comprehensive radon survey has been carried out in seven caves located in the western half of Romania's most significant karst regions. Touristic and non touristic caves were investigated with the aim to provide a reliable distribution of their radon levels and evaluate the occupational exposure and associated effective doses. Radon gas concentrations were measured with long-term diffusion type detectors during two consecutive seasons (warm and cold). All investigated caves exceed the European Union reference level of radon gas at workplaces (300 Bq/m3). The radon concentration in these caves ranges between 53 and 2866 Bq/m3, reflecting particular cave topography, season-related cave ventilation, and complex tectonic and geological settings surrounding each location. Relatively homogeneous high radon levels occur in all investigated touristic caves and in Tausoare and Vantului along their main galleries. Except for Muierii, in all the other caves radon levels are higher during the warm season, compared to the cold one. This suggests that natural cave ventilation largely controls the underground accumulation of radon. The results reported here reveal that the occupational exposure in Ursilor, Vadu Crisului, Tausoare, Vantului, and Muierii caves needs to be carefully monitored. The effective doses to workers vary between an average of 0.25 and 4.39 mSv/year depending on the measuring season. The highest values were recorded in show caves, ranging from 1.15 to 6.15 mSv/year, well above the European recommended limit, thus posing a potential health hazard upon cave guides, cavers, and scientists. PMID- 27696230 TI - Is the hypothalamic-pituitary-adrenal axis disrupted in type 2 diabetes mellitus? PMID- 27696231 TI - Combination therapy with GLP-1 analogues and SGLT-2 inhibitors in the management of diabesity: the real world experience. AB - Diabesity-obesity resulting in diabetes-is a major health problem globally because of the obesity epidemic. Several anti-diabetic medications cause weight gain and may worsen obesity, and possibly diabeisty. Two recent small retrospective cohort studies showed weight loss and diabetes improvement with combination of glucagon-like peptide-1 (GLP-1) agonists and sodium-glucose co transporter type-2 (SGLT-2) inhibitors in obese subjects. We assessed the effect of combination therapy with GLP-1 agonists and SGLT-2 inhibitors in the management of diabesity in a retrospective study at the Wolverhampton Diabetes Centre. Out of 79 patients on this combination regimen with other anti-diabetic medications, 37 cases who had follow up at 3-6 months were studied. Mean age and duration of follow up were 57.4 (+/-7.8) and 139 (+/-32.6) days, respectively. Twenty-two patients (59.5 %) were Asians. Statistically significant improvements in clinical parameters such as body weight reduction (3.07 kg), glycated haemoglobin (HbA1c) reduction (1.05 %), lower BMI (-1.13 kg/M2) and insulin dose reduction (6.8 units) were observed (p < 0.05 for all) in patients on combination regimen. Linear regression analysis showed that baseline HbA1c and baseline insulin dose were independent predictors of HbA1c reduction and insulin dose reduction, respectively. Our results suggest that combination therapy with GLP-1 agonists and SGLT-2 inhibitors is a promising option for patients with diabesity. PMID- 27696232 TI - Correlation of BRAF mutation and SUVmax levels in thyroid cancer patients incidentally detected in 18F-fluorodeoxyglucose positron emission tomography. AB - The prognostic importance of 18F-fluorodeoxyglucose avidity in primary thyroid tumor and molecular basis responsible for its mechanism has not yet been well characterized. In this study, we aimed to evaluate the correlation between the maximum standardized uptake levels and B-type Raf kinase mutation positivity in incidentally detected papillary thyroid cancer patients during 18F fluorodeoxyglucose positron emission tomography examination. We retrospectively evaluated 6873 18F-fluorodeoxyglucose-positron emission tomography scans of consecutive subjects from a database search for tumor staging in 2014 at our hospital Nuclear Medicine Center. In total, 135 patients had focal 18F fluorodeoxyglucose uptake in the thyroid. Of these, 76 patients had fine-needle aspiration biopsy. 18F-fluorodeoxyglucose-maximum standardized uptake of the positron emission tomography-detected nodules was recorded. B-type Raf kinase (V600E) mutation and p53 protein expression were evaluated in papillary thyroid cancer patients. The incidence of thyroid incidentaloma in 18F-fluorodeoxyglucose maximum standardized uptake scans was 2 % (135/6873). Of the 76 patients evaluated, 41 % (n = 31) were diagnosed papillary thyroid cancer. B-type Raf kinase mutation was positive in 51 % (17/30) of the papillary thyroid cancer patients. Maximum standardized uptake levels of the nodules (>=1 cm) were significantly higher in B-type Raf kinase-mutated papillary thyroid cancer patients than in non-mutated patients [16.6 (10.4-27.9) vs. 9.7 (6.8-11.1); P = 0.007]. Correlation analysis revealed that maximum standardized uptake was significantly associated with B-type Raf kinase mutation positivity (r = 0.519; P = 0.005). Logistic regression analysis showed an association between maximum standardized uptake and B-type Raf kinase mutation positivity even after adjustment for age and gender (P = 0.01). B-type Raf kinase mutation is closely related to 18F-fluorodeoxyglucose-positron emission tomography maximum standardized uptake levels in patients with incidentally detected papillary thyroid cancer. PMID- 27696233 TI - Clostridium difficile infection in children: epidemiology and risk of recurrence in a low-prevalence country. AB - Clostridium difficile infection (CDI) is increasingly found in children worldwide, but limited data are available from children living in southern Europe. A 6-year retrospective study was performed to investigate the epidemiology, clinical features, treatment, and risk of recurrence in Italy. Data of children with community- and hospital-acquired CDI (CA-CDI and HA-CDI, respectively) seen at seven pediatric referral centers in Italy were recorded retrospectively. Annual infection rates/10,000 hospital admissions were calculated. Logistic regression was used to investigate risk factors for recurrence. A total of 177 CDI episodes was reported in 148 children (83 males, median age 55.3 months), with a cumulative infection rate of 2.25/10,000 admissions, with no significant variability over time. The majority of children (60.8 %) had CA-CDI. Children with HA-CDI (39.2 %) had a longer duration of symptoms and hospitalization (p = 0.003) and a more common previous use of antibiotics (p = 0.0001). Metronidazole was used in 70.7 % of cases (87/123) and vancomycin in 29.3 % (36/123), with similar success rates. Recurrence occurred in 16 children (10.8 %), and 3 (2 %) of them presented a further treatment failure. The use of metronidazole was associated with a 5-fold increase in the risk of recurrence [odds ratio (OR) 5.18, 95 % confidence interval (CI) 1.1-23.8, p = 0.03]. Short bowel syndrome was the only underlying condition associated with treatment failure (OR 5.29, 95 % CI 1.17-23.8, p = 0.03). The incidence of pediatric CDI in Italy is low and substantially stable. In this setting, there is a limited risk of recurrence, which mainly concerns children treated with oral metronidazole and those with short bowel syndrome. PMID- 27696235 TI - Clinicians should not be forced to use likelihood ratios when comparing tests. PMID- 27696236 TI - Increased local recurrence in advanced parotid malignancy treated with mastoidectomy without lateral temporal bone resection. AB - OBJECTIVE: We analyzed patients with advanced parotid malignancy requiring proximal facial nerve exposure undergoing mastoidectomy versus lateral temporal bone resection to determine differences in local and distant recurrence. STUDY DESIGN: The study design is a case series with chart review. SETTING: The setting is in Tertiary care practice in Fort Worth, Texas from January1998 to January 2014. SUBJECTS AND METHODS: The study included 120 patients with advanced parotid malignancy, 82 males between 19 and 87 years, and 38 females between 26 and 83 years. Patients with no overt bone involvement were treated with parotidectomy and mastoidectomy for exposure of the proximal facial nerve, and patients with clinically suspected (radiographic imaging or clinical fixation) bone involvement were treated with parotidectomy and lateral temporal bone resection. Follow up ranged from a minimum of 18 months to 11 years following surgery. RESULTS: Sixty patients were treated with mastoidectomy and 60 were treated with lateral temporal bone resection. In patients treated with mastoidectomy, 13 had local recurrence and 7 had distal recurrence. In patients treated with lateral temporal bone resection, 2 had local recurrence while 9 had distant recurrence. Statistical analysis revealed that patients treated with mastoidectomy developed local recurrence (p = 0.0022) more commonly than those treated with lateral temporal bone resection. There was no significant difference in distant recurrence between both groups (p = 0.5949). CONCLUSIONS: Patients with advanced parotid malignancy should be treated aggressively with parotidectomy and lateral temporal bone resection regardless of bone involvement due to increased risk of local recurrence in those treated with mastoidectomy alone. LEVEL OF EVIDENCE: Level of evidence is a 4 case series. PMID- 27696234 TI - Toxin A-negative toxin B-positive ribotype 017 Clostridium difficile is the dominant strain type in patients with diarrhoea attending tuberculosis hospitals in Cape Town, South Africa. AB - The molecular epidemiology of C. difficile strains causing disease in South Africa is currently unknown. Previously, multidrug resistant ribotype (RT)017 strains were those most commonly isolated from patients with diarrhoea attending Groote Schuur Hospital in Cape Town, South Africa. This larger study aimed to investigate the molecular epidemiology and antibiotic susceptibility profiles of C. difficile strains in the greater Cape Town and regional areas. C. difficile strains were isolated from patients with diarrhoea attending hospitals in the Western Cape region of South Africa that tested positive using the GeneXpert CDiff diagnostic test. Ribotyping and multilocus variable-number tandem-repeat analysis (MLVA) were used to type isolates, and their susceptibilities to several antibiotics were determined by gradient diffusion test strips. A total of 269 non repeat C. difficile isolates were obtained. A large proportion of isolates (64.3 %) belonged to the RT017 group, many of which were clonally related when investigated by MLVA. RT017 strains were particularly prevalent in patients attending specialist tuberculosis (TB) hospitals. The majority of RT017 isolates were co-resistant to moxifloxacin and rifampicin, two antibiotics which are used intensively during anti-TB therapy. Non-RT017 strains were generally susceptible to both antibiotics. Resistance to erythromycin was observed for both groups of strains. RT017 C. difficile strains are the most commonly isolated strains from patients attending healthcare facilities in the greater Cape Town and regional areas. The presence of multidrug resistant RT017 strains in patients with diarrhoea attending local TB hospitals reflects a potential reservoir for future infections. PMID- 27696237 TI - Global Changes in Food Supply and the Obesity Epidemic. AB - PURPOSE OF REVIEW: We explore how a global shift in the food system caused by global economic growth, increase in available food per capita and in food processing is a driver of the obesity epidemic. RECENT FINDINGS: Economic development in most areas of the world has resulted in increased purchasing power and available per capita food. Supermarkets and a growing fast-food industry have transformed our dietary pattern. Ultra-processed food rich on sugars and saturated fat is now the major source of energy in most countries. The shift in food supply is considered a major driver of the obesity epidemic and the increasing prevalence of accompanying complications, such as type 2 diabetes, cardiovascular disease and cancer. However, the global shift might also have direct effects on the increase in type 2 diabetes, cardiovascular disease and cancer, independently of overweight and obesity. The shift in the food supply is a major driver of the obesity epidemic. PMID- 27696238 TI - Embryonic kidney function in a chronic renal failure model in rodents. AB - BACKGROUND: Rapid advancements have been made in alternative treatments for renal diseases. Our goal for renal regeneration is to establish a kidney graft derived from human embryonic tissues. In this study, we investigated the effects of host renal failure on the structure and activity of transplanted embryonic kidney and bladder, and found that diuretics effectively induced urine production in the transplanted kidney. METHODS: Uremic conditions were reproduced using a 5/6 renal infarction rat model. An embryonic kidney plus bladder (embryonic day 15) was isolated from a pregnant Lewis rat and transplanted into the para-aortic area of a 5/6 renal-infarcted Lewis rat. Following growth, the embryonic bladder was successfully anastomosed to the host ureter. RESULTS: We assessed graft function in terms of survival rates and found no differences between normal (n = 5) and renal failure (n = 8) groups (median survival: 70.5 vs 74.5 h; p = 0.331) in terms of survival, indicating that the grafts prolonged rat survival, even under renal failure conditions. Furosemide (n = 9) significantly increased urine volume compared with saline-treated controls (n = 7; p < 0.05), confirming that the grafts were functional. We also demonstrated the possibilities of an in vivo imaging system for determining the viability of transplanted embryonic kidney with bladder. CONCLUSION: The results of this study demonstrate that transplanted embryonic kidney and bladder can grow and function effectively, even under uremic conditions. PMID- 27696240 TI - D3R grand challenge 2015: Evaluation of protein-ligand pose and affinity predictions. AB - The Drug Design Data Resource (D3R) ran Grand Challenge 2015 between September 2015 and February 2016. Two targets served as the framework to test community docking and scoring methods: (1) HSP90, donated by AbbVie and the Community Structure Activity Resource (CSAR), and (2) MAP4K4, donated by Genentech. The challenges for both target datasets were conducted in two stages, with the first stage testing pose predictions and the capacity to rank compounds by affinity with minimal structural data; and the second stage testing methods for ranking compounds with knowledge of at least a subset of the ligand-protein poses. An additional sub-challenge provided small groups of chemically similar HSP90 compounds amenable to alchemical calculations of relative binding free energy. Unlike previous blinded Challenges, we did not provide cognate receptors or receptors prepared with hydrogens and likewise did not require a specified crystal structure to be used for pose or affinity prediction in Stage 1. Given the freedom to select from over 200 crystal structures of HSP90 in the PDB, participants employed workflows that tested not only core docking and scoring technologies, but also methods for addressing water-mediated ligand-protein interactions, binding pocket flexibility, and the optimal selection of protein structures for use in docking calculations. Nearly 40 participating groups submitted over 350 prediction sets for Grand Challenge 2015. This overview describes the datasets and the organization of the challenge components, summarizes the results across all submitted predictions, and considers broad conclusions that may be drawn from this collaborative community endeavor. PMID- 27696239 TI - A combined treatment of hydration and dynamical effects for the modeling of host guest binding thermodynamics: the SAMPL5 blinded challenge. AB - As part of the SAMPL5 blinded experiment, we computed the absolute binding free energies of 22 host-guest complexes employing a novel approach based on the BEDAM single-decoupling alchemical free energy protocol with parallel replica exchange conformational sampling and the AGBNP2 implicit solvation model specifically customized to treat the effect of water displacement as modeled by the Hydration Site Analysis method with explicit solvation. Initial predictions were affected by the lack of treatment of ionic charge screening, which is very significant for these highly charged hosts, and resulted in poor relative ranking of negatively versus positively charged guests. Binding free energies obtained with Debye Huckel treatment of salt effects were in good agreement with experimental measurements. Water displacement effects contributed favorably and very significantly to the observed binding affinities; without it, the modeling predictions would have grossly underestimated binding. The work validates the implicit/explicit solvation approach employed here and it shows that comprehensive physical models can be effective at predicting binding affinities of molecular complexes requiring accurate treatment of conformational dynamics and hydration. PMID- 27696241 TI - Effects of point mutations on the thermostability of B. subtilis lipase: investigating nonadditivity. AB - Molecular level understanding of mutational effects on stability and activity of enzymes is challenging particularly when several point mutations are incorporated during the directed evolution experiments. In our earlier study, we have suggested the lack of consistency in the effect of point mutations incorporated during the initial generations of directed evolution experiments, towards conformational stabilization of B. subtilis lipase mutants of later generations. Here, we report that the cumulative point mutations incorporated in mutants 2M (with two point mutations) to 6M (with six point mutations) possibly do not retain their original stabilizing nature in the most thermostable 12M mutant (with 12 point mutations). We have carried out MD simulations using structures incorporating reversal of different sets of point mutations to assess their effect on the conformational stability and activity of 12M. Our analysis has revealed that reversal of certain point mutations in 12M had little effect on its conformational stability, suggesting that these mutations were probably inconsequential towards the thermostability of the 12M mutant. Interestingly these mutations involved evolutionarily conserved residues. On the other hand, some of the other point mutations incorporated in nonconserved regions, appeared to contribute significantly towards the conformational stability and/or activity of 12M. Based on the analysis of dynamics of in silico mutants generated using the consensus sequence, we identified experimentally verifiable residue positions to further increase the conformational stability and activity of the 12M mutant. PMID- 27696242 TI - Absolute binding free energies for octa-acids and guests in SAMPL5 : Evaluating binding free energies for octa-acid and guest complexes in the SAMPL5 blind challenge. AB - As part of the SAMPL5 blind prediction challenge, we calculate the absolute binding free energies of six guest molecules to an octa-acid (OAH) and to a methylated octa-acid (OAMe). We use the double decoupling method via thermodynamic integration (TI) or Hamiltonian replica exchange in connection with the Bennett acceptance ratio (HREM-BAR). We produce the binding poses either through manual docking or by using GalaxyDock-HG, a docking software developed specifically for this study. The root mean square deviations for our most accurate predictions are 1.4 kcal mol-1 for OAH with TI and 1.9 kcal mol-1 for OAMe with HREM-BAR. Our best results for OAMe were obtained for systems with ionic concentrations corresponding to the ionic strength of the experimental solution. The most problematic system contains a halogenated guest. Our attempt to model the sigma-hole of the bromine using a constrained off-site point charge, does not improve results. We use results from molecular dynamics simulations to argue that the distinct binding affinities of this guest to OAH and OAMe are due to a difference in the flexibility of the host. We believe that the results of this extensive analysis of host-guest complexes will help improve the protocol used in predicting binding affinities for larger systems, such as protein substrate compounds. PMID- 27696243 TI - Social Support, Parenting, and Social Emotional Development in Young Mexican and Dominican American Children. AB - This study focused on social support and its association with child developmental outcomes, indirectly through parenting practices, in families of 4-5 year old Latino children. Data were collected from mothers and teachers of 610 Mexican American (MA) and Dominican American (DA) children. Mothers reported on perceived social support, parenting practices and children's problem and adaptive behavior functioning at home, and teachers reported on mothers' parent involvement and children's problem and adaptive behavior functioning in the classroom. Results showed that support received from family was higher than support received from school networks for both ethnic groups. Moreover, familial support was associated with child behavior, mediated by positive parenting practices, whereas support from school networks was not associated with child outcomes. During early childhood, social support from family members may be an important protective factor that can promote positive behavioral functioning among Latino children. PMID- 27696244 TI - In phyllodes tumour of the breast expression of c-kit but not of ALDH1A1 is associated with adverse clinico-pathological features. AB - Attempts at identification of an ideal prognostic/predictive biomarker in phyllodes tumour (PT) have not been fruitful so far. Studies evaluating c-kit expression in PT have shown contradictory results. Recently aldehyde dehydrogenase 1A1 (ALDH1A1) was proposed as a stem cell marker for malignant PT but its expression has not been studied in benign and borderline tumours. We aimed to evaluate expression and prognostic significance of c-kit and ALDH1A1 in different grades of PT. Epithelial and stromal c-kit and ALDH1A1 expression were studied in 104 PT cases (86 primary and 18 recurrent tumours) and compared with different clinico-pathological features and recurrence rates. Stromal c-kit expression at 1 % cutoff correlated with increasing tumour grade, larger tumour size, hypercellularity, nuclear atypia, stromal overgrowth, infiltrative margins and mitotic count. These associations, however, were lost with higher (5 or 10 %) cutoffs. Conversely, decreased c-kit expression in the epithelial component correlated with increasing tumour grade, regardless of the cutoffs used. Stromal ALDH1A1 expression did not have significant associations with tumour grade or other adverse clinico-pathological features, regardless of different cutoffs. None of the cases showed significant epithelial ALDH1A1 expression. Expression of c-kit was associated with poorer overall survival (p = 0.011), while ALDH1A1 expression was associated with shorter recurrence-free survival (p = 0.036). In conclusion, c-kit expression was associated with higher tumour grade and adverse clinico-pathological features. However, these associations are cutoff dependent, partly explaining the variability in previously reported studies. ALDH1A1 expression did not have significant correlations with tumour grade and adverse clinico-pathological variables. PMID- 27696245 TI - Immunophenotypic differences between neoplastic and non-neoplastic androgen producing cells containing and lacking Reinke crystals. AB - We performed a detailed morphologic, immunophenotypic, and endocrine characterization of neoplastic and non-neoplastic lesions of androgen-producing cells known to harbor or lack Reinke crystals (RCs) with an aim to provide further insight into the nature of these cells and crystals. Study cases were selected from the files of participating hospitals and subclassified according to current classifications: 20 with Leydig cell tumors (LCTs), 2 with testicular adrenal rest tumors (TARTs), 2 with testicular tumors of adrenogenital syndrome (TTAGS), and 2 with androgen insensitivity syndrome (AIS). An extensive immunophenotypic panel including markers used in sex cord-stromal cell tumors, androgen hormones, enzymes, and receptors was applied to the cases and 10 non tumoral adrenal glands. Non-tumoral tissues were scored separately. RCs were present in 90 % of LCT cases and all cases with normal Leydig cells; RCs stained specifically with calretinin and 3beta-hydroxysteroid dehydrogenase (3BHSD) and were present only in cells with high concomitant expression of both proteins, a phenotype unique to Leydig cells and LCTs. Leydig cells from AIS cases lack RCs due to decreased expression of 3BHSD. Calretinin is decreased in testicular adrenal-like tumors and absent in normal adrenocortical cells, which explain why they lack RCs. Calretinin expression in androgen-producing cells is independent from androgen receptors and androgen synthesis. RCs represent for the most part, if not exclusively, crystallized forms of a 3BHSD/calretinin complex. Androgen producing cells containing and lacking RCs differ mainly in the level of expression of these proteins and androgen receptors. PMID- 27696246 TI - The Importance of Properly Compensating for Head Movements During MEG Acquisition Across Different Age Groups. AB - Unlike EEG sensors, which are attached to the head, MEG sensors are located outside the head surface on a fixed external device. Subject head movements during acquisition thus distort the magnetic field distributions measured by the sensors. Previous studies have looked at the effect of head movements, but no study has comprehensively looked at the effect of head movements across age groups, particularly in infants. Using MEG recordings from subjects ranging in age from 3 months through adults, here we first quantify the variability in head position as a function of age group. We then combine these measured head movements with brain activity simulations to determine how head movements bias source localization from sensor magnetic fields measured during movement. We find that large amounts of head movement, especially common in infant age groups, can result in large localization errors. We then show that proper application of head movement compensation techniques can restore localization accuracy to pre movement levels. We also find that proper noise covariance estimation (e.g., during the baseline period) is important to minimize localization bias following head movement compensation. Our findings suggest that head position measurement during acquisition and compensation during analysis is recommended for researchers working with subject populations or age groups that could have substantial head movements. This is especially important in infant MEG studies. PMID- 27696247 TI - Characterization of the spatial variability of soil available zinc at various sampling densities using grouped soil type information. AB - The influence of anthropogenic activities and natural processes involved high uncertainties to the spatial variation modeling of soil available zinc (AZn) in plain river network regions. Four datasets with different sampling densities were split over the Qiaocheng district of Bozhou City, China. The difference of AZn concentrations regarding soil types was analyzed by the principal component analysis (PCA). Since the stationarity was not indicated and effective ranges of four datasets were larger than the sampling extent (about 400 m), two investigation tools, namely F3 test and stationarity index (SI), were employed to test the local non-stationarity. Geographically weighted regression (GWR) technique was performed to describe the spatial heterogeneity of AZn concentrations under the non-stationarity assumption. GWR based on grouped soil type information (GWRG for short) was proposed so as to benefit the local modeling of soil AZn within each soil-landscape unit. For reference, the multiple linear regression (MLR) model, a global regression technique, was also employed and incorporated the same predictors as in the GWR models. Validation results based on 100 times realization demonstrated that GWRG outperformed MLR and can produce similar or better accuracy than the GWR approach. Nevertheless, GWRG can generate better soil maps than GWR for limit soil data. Two-sample t test of produced soil maps also confirmed significantly different means. Variogram analysis of the model residuals exhibited weak spatial correlation, rejecting the use of hybrid kriging techniques. As a heuristically statistical method, the GWRG was beneficial in this study and potentially for other soil properties. PMID- 27696248 TI - Influences of the Results from STRIVE Trial on the Combination Androgen Depletion Therapy for Advanced Prostate Cancer. AB - The clinical efficacy of combined therapy (CAB) has been clearly recognized by the results of the STRIVE trial. Although enzalutamide has shown a stronger effect on CRPC, bicultamide, a classical anti-androgen, has shown a significant effect. In addition, it can be deduced that CAB is a strong tool for hormone naive advanced prostate cancer. Cost-effective evaluation for CAB with bicultamide or enzalutamide is warranted, especially for the resource-limited cohort. PMID- 27696249 TI - Adoption consideration and concerns among young adult female cancer survivors. AB - PURPOSE: We compared adoption consideration between female young adult cancer survivors and women of the same age in the general US population, hypothesizing that cancer survivors who desired children would report greater interest in adoption than an age-adjusted general population sample who desired children. METHODS: After age-standardizing the cancer survivor cohort to match the age distribution of the 2006-2010 National Survey for Family Growth (NSFG), we estimated adoption consideration among women age 18-35 years who wanted a (another) child in the two cohorts overall and within age groups. We assessed characteristics and concerns related to adoption consideration among cancer survivors. RESULTS: Among cancer survivors, 81.6 % (95 % CI 75.7-87.6) reported that they would consider adoption compared to 40.3 % (95 % CI 40.3-40.3) of women in the general population. While over 80 % of the cancer survivor sample reported that they would consider adoption, only 15 % of cancer survivors reported no concerns about adoption. The most common concerns were desire for a biological child (48 %), expense (45 %), adoption agency candidacy (41 %), and needing more information (39 %). CONCLUSION: We observed a twofold higher interest in adoption when comparing the cancer survivor with the general population, suggesting that adoption is a consideration for many young women who have survived cancer. IMPLICATIONS FOR CANCER SURVIVORS: Adoption is an important family-building option for those who want to have a child but are unable to or choose not to have a biological child. However, young adult survivors may need more support to understand and navigate this process. PMID- 27696250 TI - "Physical exercise and dementia in patients with type 2 diabetes mellitus". Authors' reply. PMID- 27696251 TI - Targeted next-generation sequencing for TP53, RAS, BRAF, ALK and NF1 mutations in anaplastic thyroid cancer. AB - Anaplastic thyroid carcinoma (ATC) is the most aggressive thyroid cancer with a median survival of 4-6 months. Identification of mutations contributing to aberrant activation of signaling cascades in ATC may provide novel opportunities for targeted therapy. Thirty-nine ATC samples were studied by next-generation sequencing (NGS) with an established gene panel. High quality readout was obtained in 30/39 ATC. Twenty-eight ATC harbored a mutation in at least one of the studied genes: TP53 (18/30), NF1 (11/30), ALK (6/30), NRAS (4/30), ATRX (3/30), BRAF (2/30), HRAS (2/30), KRAS (1/30). In 17/30 ATC (54 %) mutations were found in two or more genes. Twenty-one of the identified variants are listed in COSMIC as somatic mutations reported in other cancer entities. In three ATC samples no mutations were detected and none of the ATCs was positive for BRAFV600E. The most frequent mutations were found in TP53 (60 %), followed by NF1 (37 %). ALK mutations were detected in 20 % of ATC and were more frequent than RAS or BRAF mutations. ATRX mutations were identified in 10 % of the ATC samples. These sequencing data from 30 ATC samples demonstrate the accumulation of genetic alterations in ATC because in 90 % of samples mutations were already found in the investigated nine genes alone. Mutations were found with high prevalence in established tumor suppressor and oncogenes in ATC, such as TP53 and H/K/NRAS, but also, although less frequent, in genes that may harbor the potential for targeted treatment in a subset of ATC patients, such as ALK and NF1. PMID- 27696252 TI - Chronic hyperglycemia affects bone metabolism in adult zebrafish scale model. AB - Type II diabetes mellitus is a metabolic disease characterized by chronic hyperglycemia that induce other pathologies including diabetic retinopathy and bone disease. The mechanisms implicated in bone alterations induced by type II diabetes mellitus have been debated for years and are not yet clear because there are other factors involved that hide bone mineral density alterations. Despite this, it is well known that chronic hyperglycemia affects bone health causing fragility, mechanical strength reduction and increased propensity of fractures because of impaired bone matrix microstructure and aberrant bone cells function. Adult Danio rerio (zebrafish) represents a powerful model to study glucose and bone metabolism. Then, the aim of this study was to evaluate bone effects of chronic hyperglycemia in a new type II diabetes mellitus zebrafish model created by glucose administration in the water. Fish blood glucose levels have been monitored in time course experiments and basal glycemia was found increased. After 1 month treatment, the morphology of the retinal blood vessels showed abnormalities resembling to the human diabetic retinopathy. The adult bone metabolism has been evaluated in fish using the scales as read-out system. The scales of glucose-treated fish didn't depose new mineralized matrix and shown bone resorption lacunae associated with an intense osteoclast activity. In addition, hyperglycemic fish scales have shown a significant decrease of alkaline phosphatase activity and increase of tartrate-resistant acid phosphatase activity, in association with alterations in other bone-specific markers. These data indicates an imbalance in bone metabolism, which leads to the osteoporotic like phenotype visualized through scale mineral matrix staining. The zebrafish model of hyperglycemic damage can contribute to elucidate in vivo the molecular mechanisms of metabolic changes, which influence the bone tissues regulation in human diabetic patients. PMID- 27696253 TI - Vitamin D and gallstone disease-A population-based study. AB - Gallstone disease is highly prevalent in the general population and is a major gastrointestinal cause of hospital admissions. The objectives were to determine whether circulating levels of 25-hydroxyvitamin D were associated to ultrasound proven gallstones or cholecystectomy in a general population sample. Determinants of vitamin D status were also explored. A random sample of 4130 people from the population of Copenhagen with ages 41-71 years were invited (N = 4130) and 2650 participants were included. Ultrasound examinations were performed to assess gallstone status and blood samples were drawn to assess 25-hydroxyvitamin D and biomarkers of renal and hepatic function. Gallstone disease was found in 422 participants. Associations were estimated by logistic regression models. Levels of 25-hydroxyvitamin D was not significantly associated with gallstone disease. Time of birth during low vitamin D exposure was associated with gallstone disease (gallstone prevalence 18.0 versus 14.4 %, odds ratio 1.33, 95 % confidence interval [1.07; 1.65]). Highest quartile of cystatin C was significantly associated with gallstone disease (gallstone prevalence 22.1 versus 12.0 %, odds ratio 1.53, 95 % confidence interval [1.08; 2.18]). Serum levels of creatinine and alanine amino transferase were not associated with gallstone disease. Sensitivity analyses excluding participants with cholecystectomy did not alter results significantly. No association between 25-hydroxyvitamin D and gallstone disease was identified. Findings suggest gallstones to be associated to low vitamin D exposure in utero and to renal failure suggesting that vitamin D might have an impact on gallstone disease. Future studies should explore associations for vitamin D and gallstone disease prospectively. PMID- 27696254 TI - MGUS and Smoldering Multiple Myeloma: Diagnosis and Epidemiology. AB - Monoclonal gammopathy of undetermined significance (MHUS) is characterized by the presence of a serum M-protein less than 3 g/dL, less than 10 % clonal plasma cells in the bone marrow, and the absence of myeloma-defining event. Smoldering multiple myeloma (SMM) is an asymptomatic disorder characterized by the presence of >=3 g/dL serum M-protein and/or 10-60 % bone marrow plasma cell infiltration with no myeloma-defining event. The risk of progression to multiple myeloma (MM) requiring therapy varies greatly for individual patients, but it is uniform and 1 % per year for MGUS, while higher (10 % per year) and not uniform for SMM patients. The definition of MM was recently revisited patients previously labeled as SMM with a very high risk of progression (80-90 % at 2 years) were included in the updated definition of MM requiring therapy. The standard of care is observation for MGUS patients and although this also applies for SMM, a recent randomized trial targeting high-risk SMM showed that early intervention was associated with better progression-free and overall survival. Biomarkers have become an integrated part of diagnostic criteria for MM requiring therapy, as well as clinical risk stratification of patients with SMM. This paper reviews and discusses clinical implications for MGUS and SMM patients. PMID- 27696255 TI - Vision Statement for Multiple Myeloma: Future Directions. AB - There has been great progress in the management and patient outcome in multiple myeloma due to the use of novel agents including immunomodulatory drugs and proteasome inhibitors; nonetheless, novel agents remain an urgent need. The three promising Achilles heals or vulnerabilities to be targetted in novel therapies include: protein degradation by the ubiquitin proteasome or aggresome pathways; restoring autologous antimyeloma immunity; and targeting aberrant biology resulting from constitutive and ongoing DNA damage in tumour cells. Scientifically based therapies targeting these vulnerabilities used early in the disease course, ie smouldering multiple myeloma, have the potential to significantly alter the natural history and transform myeloma into a chronic and potentially curable disease. PMID- 27696256 TI - Genomic Aberrations in Multiple Myeloma. AB - Multiple myeloma (MM) is a genetically complex disease. The past few years have seen an evolution in cancer research with the emergence of next-generation sequencing (NGS), enabling high throughput sequencing of tumors-including whole exome, whole genome, RNA, and single-cell sequencing as well as genome-wide association study (GWAS). A few inherited variants have been described, counting for some cases of familial disease. Hierarchically, primary events in MM can be divided into hyperdiploid (HDR) and nonhyperdiploid subtypes. HRD tumors are characterized by trisomy of chromosomes 3, 5, 7, 9, 11, 15, 19, and/or 21. Non HRD tumors harbor IGH translocations, mainly t(4;14), t(6;14), t(11;14), t(14;16), and t(14;20). Secondary events participate to the tumor progression and consist in secondary translocation involving MYC, copy number variations (CNV) and somatic mutations (such as mutations in KRAS, NRAS, BRAF, P53). Moreover, the dissection of clonal heterogeneity helps to understand the evolution of the disease. The following review provides a comprehensive review of the genomic landscape in MM. PMID- 27696257 TI - Epigenetics in Multiple Myeloma. AB - Multiple myeloma is characterized by clonal proliferation of plasma cells within the bone marrow resulting in anemia, lytic bone lesions, hypercalcemia, and renal impairment. Despite advanced in our understanding of this complex disease in recent years, it is still considered an incurable malignancy. This is, in part, due to the highly heterogenous genomic and phenotypic nature of the disease, which is to date incompletely understood. It is clear that a deeper level of knowledge of the biological events underlying the development of these diseases is needed to identify new targets and generate effective novel therapies. MicroRNAs (miRNAs), which are single strand, 20-nucleotide, noncoding RNA's, are key regulators of gene expression and have been reported to exert transcriptional control in multiple myeloma. miRNAs are now recognized to play a role in many key areas such as cellular proliferation, differentiation, apoptosis and stress response. Substantial advances have been made in recent years in terms of our understanding of the biological role of miRNAs in a diverse range of hematological and solid malignancues, In multiple myeloma these advances have yielded new information of prognostic and diagnostic relevance which have helped to shed light on epigenetic regulation in this disease. PMID- 27696258 TI - Role of Endothelial Cells and Fibroblasts in Multiple Myeloma Angiogenic Switch. AB - Multiple myeloma (MM) mainly progresses in bone marrow (BM). Therefore, signals from the BM microenvironment are thought to play a critical role in maintaining plasma cell growth, migration, and survival. Reciprocal positive and negative interactions between plasma cells and microenvironmental cells, including endothelial cells (ECs) and fibroblasts may occur. The BM neovascularization is a constant hallmark of MM, and goes hand in hand with progression to leukemic phase. Microenvironmental factors induce MMECs and fibroblasts to become functionally different from monoclonal gammopathy of undetermined significance (MGUS) ECs (MGECs), i.e., to acquire an overangiogenic phenotype, and be similar to transformed cells. These alterations play an important role in MM progression and may represent new molecular markers for prognostic stratification of patients and prediction of response to antiangiogenic drugs, as well as new potential therapeutic targets. PMID- 27696259 TI - Targeting the Bone Marrow Microenvironment. AB - Unprecedented advances in multiple myeloma (MM) therapy during the last 15 years are predominantly based on our increasing understanding of the pathophysiologic role of the bone marrow (BM) microenvironment. Indeed, new treatment paradigms, which incorporate thalidomide, immunomodulatory drugs (IMiDs), and proteasome inhibitors, target the tumor cell as well as its BM microenvironment. Ongoing translational research aims to understand in more detail how disordered BM-niche functions contribute to MM pathogenesis and to identify additional derived targeting agents. One of the most exciting advances in the field of MM treatment is the emergence of immune therapies including elotuzumab, daratumumab, the immune checkpoint inhibitors, Bispecific T-cell engagers (BiTes), and Chimeric antigen receptor (CAR)-T cells. This chapter will review our knowledge on the pathophysiology of the BM microenvironment and discuss derived novel agents that hold promise to further improve outcome in MM. PMID- 27696260 TI - Multiple Myeloma Minimal Residual Disease. AB - Assessment of minimal residual disease (MRD) is becoming standard diagnostic care for potentially curable neoplasms such as some acute leukemias as well as chronic myeloid and lymphocytic leukemia. Although multiple myeloma (MM) remains as an incurable disease, around half of the patients achieve complete remission (CR), and recent data suggests increasing rates of curability with "total-therapy-like" programs. This landscape is likely to be improved with the advent of new antibodies and small molecules. Therefore, conventional serological and morphological techniques have become suboptimal for sensitive evaluation of highly effective treatment strategies. Although, existing data suggests that MRD could be used as a biomarker to evaluate treatment efficacy, help on therapeutic decisions, and act as surrogate for overall survival, the role of MRD in MM is still a matter of extensive debate. Here, we review the different levels of remission used to define depth of response in MM and their clinical significance, as well as the prognostic value and unique characteristics of MRD detection using immunophenotypic, molecular, and imaging techniques. Key facts The higher efficacy of new treatment strategies for MM demand the incorporation of highly sensitive techniques to monitor treatment efficacy MRD could be used as a more potent surrogate biomarker for survival than standard CR We need to understand the pros and cons of the different MRD techniques The time has come to incorporate highly sensitive, cost-effective, readily available, and standardized MRD techniques into clinical trials to assess its role in therapeutic decisions. PMID- 27696261 TI - Treatment of Newly Diagnosed Elderly Multiple Myeloma. AB - Multiple myeloma (MM) is a disease of the elderly, with a median age at diagnosis of approximately 70 years old, and more than 30 % of patients aged >75 years. This latter and very elderly population is going to significantly rise in the near future given the increase in life expectancy in Western countries, and, most importantly, global health status of elderly patients is improving, justifying appropriate treatments. Changes in treatment paradigm from the old melphalan prednisone regimen used since the 1970s to its use as a backbone in a nontransplant setting since the late 1990s have highlighted different subgroups in elderly MM. Some "elderly" patients could be treated like transplant eligible patients, more likely those aged between 65 and the early 70; while a second group would rather be referred to current approved treatment regimens for the non transplant setting. A dose-intensity approach seems reasonable for this group, aiming for the best response, eventually the complete response (CR) or even minimal residual disease (MRD). The advent of novel agents such as thalidomide, bortezomib, and most recently lenalidomide have allowed a major improvement in outcome as compared to historical combinations, and soon the novel class of monoclonal antibodies should help to further improve these patients' survival. Nonetheless, elderly patients are more susceptible to side effects and are often unable to tolerate full drug doses, and thus require lower dose intensity regimens, or novel drugs or combinations with more favourable safety profile. Recent developments in MM have focused on identifying these vulnerable patients through geriatric assessment and novel myeloma scoring system, including the notions of frailty, disability and comorbidities. Eventually, we have reached an era in which we should be able to provide individualized treatment strategies and drug doses-"tailored therapy"-to improve tolerability and optimize efficacy and ultimately survival for most elderly MM patients. PMID- 27696262 TI - Management of Transplant-Eligible Patients with Newly Diagnosed Multiple Myeloma. AB - Treatment approaches for newly diagnosed myeloma have changed considerably during the past decade, along with a better understanding of the disease heterogeneity. Availability of new drug classes such as proteasome inhibitors and immunomodulatory drugs, and use of these drugs in combinations have led to higher response rates and deeper responses in the vast majority of patients with newly diagnosed myeloma. In addition to improved efficacy, these regimens are tolerated better than those with conventional chemotherapy drugs, which have reduced the early mortality seen in MM, while allowing for successful stem cell collection in patients undergoing stem cell transplant consolidation. Ongoing clinical trials with newer drugs such as monoclonal antibodies are being explored as options for newly diagnosed MM. The optimal regimen continues to evolve and is often dictated by the intent to transplant, age and comorbidities. Despite the increasing response rates seen with the new regimens, autologous stem cell transplantation remains an effective modality for consolidation, further deepening the responses seen with the initial therapy. Post-transplant approaches have further added to the efficacy of this platform with both post-transplant consolidation and maintenance demonstrating value in clinical trials. Currently, the combination of an effective initial therapy followed by one or two autologous stem cell transplants, with or without consolidation followed by maintenance appear to provide the maximum benefit in terms of duration of disease control for patients with newly diagnosed MM. PMID- 27696263 TI - Treatment of Relapsed/Refractory Multiple Myeloma. AB - Survival outcomes of patients with Multiple Myeloma (MM) have improved over the last decade due to the introduction of novel agents such as the immunomodulatory drugs thalidomide, lenalidomide (Len) and pomalidomide, and the proteasome inhibitors bortezomib (BTZ) and carfilzomib [1, 2]. However, despite these major advances, MM remains largely incurable and almost all patients relapse and require additional therapy [3]. The successful introduction of next generation novel agents including oral proteasome inhibitors, deacetylase inhibitors, and especially monoclonal antibodies as part of immunotherapy promises to further improve outcome. PMID- 27696264 TI - Treatment of MM: Upcoming Novel Therapies. AB - Treatment for myeloma has dramatically changed over the past decade, as has overall survival, due in large part to the development of new targeted agents. While proteasome inhibitors and immunomodulatory agents have contributed to improved outcomes, additional new options remain an unmet medical need. Classes of emerging agents include those targeting epigenetics, such as histone deacetylase inhibitors, monoclonal antibodies, and other emerging targets, such as kinesin spindle protein (KSP) inhibitors, cyclin dependent kinase (CDK) inhibitors, and nuclear protein export inhibitors. Future treatment approaches will need to identify how and when to incorporate these treatment options to optimally treat patients with relapsed or refractory myeloma. PMID- 27696265 TI - Role of the Immune Response in Disease Progression and Therapy in Multiple Myeloma. AB - Multiple myeloma (MM) is a hematologic cancer derived from malignant plasma cells within the bone marrow. Unlike most solid tumors, which originate from epithelial cells, the myeloma tumor is a plasma cell derived from the lymphoid cell lineage originating from a post-germinal B-cell. As such, the MM plasma cell represents an integral component of the immune system in terms of both antibody production and antigen presentation, albeit not efficiently. This fundamental difference has significant implications when one considers the implications of immunotherapy. In the case of lymphoid malignancies such as myeloma, immune-based strategies must take into consideration this important difference, potentially necessitating immunotherapy targeted toward MM to be altered from that targeted at solid tumors. Typically, the immune system "surveys" cells within our body and is able to recognize and attack cancerous cells that may arise. However, some cancer cells are able to evade immune surveillance and continue to flourish, causing disease. The major mechanism leading to an effective tumor-specific response is one that enables effective antigen processing and presentation with subsequent T cell activation, expansion, and effective trafficking to the tumor site. Plasma cells employ several mechanisms to escape immune surveillance which include altered interactions with T-cells, DCs, bone marrow stromal cells (BMSC's), and natural killer cells (NK Cells) that can be mediated by immunosuppressive cells such as and myeloid-derived suppressor cells (MDSC's) and cytokines such as IL 10, TGFbeta, and IL-6 as well as down-regulation of the antigen processing machinery. Many therapies have been developed to reestablish a functional immune system in MM patients. These include adoptive T-cell therapies to deliver more tumor-specific T-cells, vaccines to increase the tumor-specific precursor frequency of the endogenous T-cell population, immunomodulatory agents (IMiDs) such as thalidomide and lenalidomide to enhance global endogenous immunity, immunostimulatory cytokines, and antibodies to specifically target tumor-specific cell-surface proteins or cytokines. This review will dissect these various approaches currently being explored in MM as well as highlight some future directions for myeloma-specific immune-based strategies. PMID- 27696266 TI - Transplantation for Multiple Myeloma. AB - Multiple myeloma is a disorder characterized by accumulation of malignant plasma cells in the bone marrow, hypercalcemia, monoclonal protein, and end organ damage. Recently newer generation proteosome inhibitors, monoclonal antibodies and novel agents have been approved by FDA, which is undoubtedly increasing life expectancy of the patients. However, hematopoietic stem cell transplantation still remains the cornerstone of the treatment. In this chapter, we are discussing the autologous stem cell transplant, allogeneic stem cell transplant and total therapy trials with outcomes. PMID- 27696267 TI - Bone Disease in Multiple Myeloma. AB - Bone involvement represented by osteolytic bone disease (OBD) or osteopenia is one of the pathognomonic and defining characteristics of multiple myeloma (MM). Nearly 90 % of patients with MM develop osteolytic bone lesions, frequently complicated by skeletal-related events (SRE) such as severe bone pain, pathological fractures, vertebral collapse, hypercalcemia, and spinal cord compression. All of these not only result in a negative impact on quality of life but also adversely impact overall survival. OBD is a consequence of increased osteoclast (OC) activation along with osteoblast (OB) inhibition, resulting in altered bone remodeling. OC number and activity are increased in MM via cytokine deregulation within the bone marrow (BM) milieu, whereas negative regulators of OB differentiation suppress bone formation. Inhibition of osteolysis and stimulation of OB differentiation leads to reduced tumor growth in vivo. Therefore, novel agents targeting OBD are promising therapeutic strategies not only for the treatment of MM OBD but also for the treatment of MM. Several novel agents in addition to bisphosphonates are currently under investigation for their positive effect on bone remodeling via OC inhibition or OB stimulation. Future studies will look to combine or sequence all of these agents with the goal of not only alleviating morbidity from MM OBD but also capitalizing on the resultant antitumor activity. PMID- 27696268 TI - Immunoglobulin Light Chain Systemic Amyloidosis. AB - Immunoglobulin light chain amyloidosis (AL) is a rare, complex disease caused by misfolded free light chains produced by a usually small, indolent plasma cell clone. Effective treatments exist that can alter the natural history, provided that they are started before irreversible organ damage has occurred. The cornerstones of the management of AL amyloidosis are early diagnosis, accurate typing, appropriate risk-adapted therapy, tight follow-up, and effective supportive treatment. The suppression of the amyloidogenic light chains using the cardiac biomarkers as guide to choose chemotherapy is still the mainstay of therapy. There are exciting possibilities ahead, including the study of oral proteasome inhibitors, antibodies directed at plasma cell clone, and finally antibodies attacking the amyloid deposits are entering the clinic, offering unprecedented opportunities for radically improving the care of this disease. PMID- 27696269 TI - Waldenstrom Macroglobulinemia: Genomic Aberrations and Treatment. AB - Waldenstrom macroglobulinemia (WM) is a rare, indolent, and monoclonal immunoglobulin M-associated lymphoplasmacytic disorder with unique clinicopathologic characteristics. Over the past decade, remarkable progress has occurred on both the diagnostic and therapeutic fronts in WM. A deeper understanding of the disease biology emanates from the seminal discoveries of myeloid differentiation primary response 88 (MYD88) L265P somatic mutation in the vast majority of cases and C-X-C chemokine receptor, type 4, mutations in about a third of patients. Although WM remains an incurable malignancy, and the indications to initiate treatment are largely unchanged, the therapeutic armamentarium continues to expand. Acknowledging the paucity of high-level evidence from large randomized controlled trials, herein, we evaluate the genomic aberrations and provide a strategic framework for the management in the frontline as well as the relapsed/refractory settings of symptomatic WM. PMID- 27696270 TI - New technologies - new insights into the pathogenesis of hepatic encephalopathy. AB - Hepatic encephalopathy (HE) is a neuropsychiatric syndrome which frequently accompanies acute or chronic liver disease. It is characterized by a variety of symptoms of different severity such as cognitive deficits and impaired motor functions. Currently, HE is seen as a consequence of a low grade cerebral oedema associated with the formation of cerebral oxidative stress and deranged cerebral oscillatory networks. However, the pathogenesis of HE is still incompletely understood as liver dysfunction triggers exceptionally complex metabolic derangements in the body which need to be investigated by appropriate technologies. This review summarizes technological approaches presented at the ISHEN conference 2014 in London which may help to gain new insights into the pathogenesis of HE. Dynamic in vivo 13C nuclear magnetic resonance spectroscopy was performed to analyse effects of chronic liver failure in rats on brain energy metabolism. By using a genomics approach, microRNA expression changes were identified in plasma of animals with acute liver failure which may be involved in interorgan interactions and which may serve as organ-specific biomarkers for tissue damage during acute liver failure. Genomics were also applied to analyse glutaminase gene polymorphisms in patients with liver cirrhosis indicating that haplotype-dependent glutaminase activity is an important pathogenic factor in HE. Metabonomics represents a promising approach to better understand HE, by capturing the systems level metabolic changes associated with disease in individuals, and enabling monitoring of metabolic phenotypes in real time, over a time course and in response to treatment, to better inform clinical decision making. Targeted fluxomics allow the determination of metabolic reaction rates thereby discriminating metabolite level changes in HE in terms of production, consumption and clearance. PMID- 27696272 TI - Interest in Collaborative, Practice-Based Research Networks in Pediatric Refugee Health Care. AB - Over the last decade, approximately 200,000 refugee children have resettled across the United States. This population is dispersed, resulting in limited data. Collaborative research networks, where clinicians across distinct practice sites work together to answer research questions, can improve the evidence base regarding clinical care. We distributed a web-based survey to pediatric refugee providers around North America to assess priorities, perceived barriers and benefits to collaborative research. We recruited 57 participants. Of respondents, 89 % were interested in collaborative research, prioritizing: (1) access to health care (33 %), (2) mental health (24 %) and (3) nutrition/growth (24 %). Perceived benefits were "improving clinical practice" (98 %) and "raising awareness about the needs of pediatric refugees" (94 %). Perceived barriers were "too many other priorities" (89 %) and "lack of funding for data entry" (78 %). There is widespread interest in collaborative networks around pediatric refugee healthcare. A successful network will address barriers and emphasize priorities. PMID- 27696271 TI - The Role of Autophagy in the Maintenance of Stemness and Differentiation of Mesenchymal Stem Cells. AB - Regulated self-consumption, also known as autophagy, is an evolutionary conserved process that degrades cellular components by directing them to the lysosomal compartment of eukaryotic cells. As a major intracellular degradation and recycling pathway, autophagy is crucial for maintaining and remodeling cellular homeostasis during normal cellular and tissue development. Recent studies have demonstrated that autophagy is necessary for the maintenance of cellular stemness and for a number of differentiation processes, including the lineage determination of mesenchymal stem cells. These are multipotent progenitor cells with self-renewal capacities that can give rise to a subset of tissues and thus hold a consistent potential in regenerative medicine. Here, we review the current literature on the complex liaison between autophagy induced by various extra- or intracellular stimuli and the molecular targets that affect mesenchymal stem cells proliferation and differentiation. PMID- 27696273 TI - Screening for intermediate CGG alleles of FMR1 gene in male Iranian patients with Parkinsonism. AB - Male carriers of an expansion of CGG alleles (with 55-200 CGG repeats) in the FMR1 gene are affected with Fragile X-associated tremor/ataxia syndrome (FXTAS). On the other hand, individuals with Parkinson's disease (PD) or Parkinsonism spectrum disorders may have some clinical features that overlap with FXTAS. To investigate the possible association between PD and FMR1 expanded alleles, we screened a total of 154 male PD patients and 190 gender- and age-matched healthy control subjects from Iran. Eleven intermediate allele carriers (7.14 %) were detected among PD patients, compared with three carriers (1.57 %) among the controls (P = 0.01). No pre-mutation carriers were identified. Our results indicate that there is a potential association between FMR1 intermediate expanded alleles and PD. PMID- 27696274 TI - Early rehabilitation: benefits in patients with severe acquired brain injury. AB - Establish the best time to start rehabilitation by means of scientific evidence. Observational study in patients with a diagnosis of Severe Brain Injury who received intensive inpatient rehabilitation after acute care. 1470 subjects enrolled: 651 with Traumatic Brain Injury (TBI) and 819 with Non-TBI. Male gender was prevalent in the population study, but sex distribution was not different among groups, with a prevalence of male gender in both populations. This project involved 29 rehabilitation facilities for Severe ABI. The registry was an electronic database, remained active only during the period of data collection. The patients were divided into three different categories according to the time interval from brain injury to inpatient rehabilitation admission and demographic and clinical data were collected. Etiology, time interval from injury to inpatient rehabilitation, disability severity, the presence of tracheostomy at admission to the rehabilitation facility, rehabilitation length of stay and transfer back to acute care wards because of medical, surgical or neurosurgical complications. The interval from brain injury to rehabilitation facilities admission increases along with age, brain injury severity according to DRS scores, the presence of a tracheal tube and the percentage of transfers back to acute care wards from rehabilitation facilities, because of medical, surgical or neurosurgical complications. The better recovery and more positive outcomes, reported as resulting from early rehabilitation, may be due more to less severity of brain injury and fewer complications in the acute and post-acute phase than to when the rehabilitation starts. PMID- 27696275 TI - School Bullies' Intention to Change Behavior Following Teacher Interventions: Effects of Empathy Arousal, Condemning of Bullying, and Blaming of the Perpetrator. AB - This study examines how bullies' perceptions of how they were treated by a teacher (or other school personnel) during discussions aimed at putting an end to bullying influenced their intention to change their behavior. After each discussion, which took place as part of the implementation of an anti-bullying program, bullies anonymously reported the extent to which they felt that the teacher aroused their empathy for the victim, condemned their behavior, or blamed them. Half of the schools implementing the program were instructed to handle these discussions in a confrontational way-telling the bully that his behavior is not tolerated-while the other half were instructed to use a non-confronting approach. Schools were randomly assigned to one of the two approaches. A total of 341 cases (188 in primary and 153 in secondary schools) handled in 28 Finnish schools were analyzed. Regression analyses showed that attempts at making bullies feel empathy for the victim and condemning their behavior both increased bullies' intention to stop. Blaming the bully had no significant effect. Bullies' intention to change was the lowest when both empathy-arousal and condemning behavior were low. The effects of empathy arousal were stronger when condemning the behavior was low (and vice versa), suggesting that teachers tackling bullying should make sure to use at least one of these strategies. When choosing not to raise the child's empathy, clear reprobation of the behavior is key. PMID- 27696276 TI - Risk factors for postoperative complications in robotic general surgery. AB - The feasibility and safety of robotically assisted procedures in general surgery have been reported from various groups worldwide. Because postoperative complications may lead to longer hospital stays and higher costs overall, analysis of risk factors for postoperative surgical complications in this subset of patients is clinically relevant. The goal of this study was to identify risk factors for postoperative morbidity after robotic surgical procedures in general surgery. We performed an observational monocentric retrospective study. All consecutive robotic surgical procedures from November 2001 to December 2013 were included. One thousand consecutive general surgery patients met the inclusion criteria. The mean overall postoperative morbidity and major postoperative morbidity (Clavien >III) rates were 20.4 and 6 %, respectively. This included a conversion rate of 4.4 %, reoperation rate of 4.5 %, and mortality rate of 0.2 %. Multivariate analysis showed that ASA score >3 [OR 1.7; 95 % CI (1.2-2.4)], hematocrit value <38 [OR 1.6; 95 % CI (1.1-2.2)], previous abdominal surgery [OR 1.5; 95 % CI (1-2)], advanced dissection [OR 5.8; 95 % CI (3.1-10.6)], and multiquadrant surgery [OR 2.5; 95 % CI (1.7-3.8)] remained independent risk factors for overall postoperative morbidity. It also showed that advanced dissection [OR 4.4; 95 % CI (1.9-9.6)] and multiquadrant surgery [OR 4.4; 95 % CI (2.3-8.5)] remained independent risk factors for major postoperative morbidity (Clavien >III). This study identifies independent risk factors for postoperative overall and major morbidity in robotic general surgery. Because these factors independently impacted postoperative complications, we believe they could be taken into account in future studies comparing conventional versus robot-assisted laparoscopic procedures in general surgery. PMID- 27696277 TI - Anal metastasis from rectal adenocarcinoma. AB - The metastasis of rectal cancer to the anus is rare. Here, we report a case of advanced rectal cancer, which had a diffuse venous invasion with anal metastasis and multiple lymph node and liver metastases. The patient was a 72-year-old woman who complained of perianal pain and fresh blood in the stools for 6 months. She had neither history of fistula-in-ano nor anal surgery. Digital examination revealed a 2-cm tumor at the 7 o'clock position, and the barium enema and colonoscopy confirmed advanced rectal cancer. Abdominal computed tomography revealed thickness of the upper rectum wall, right inguinal lymph node of 10 mm and multiple liver metastases. Laparoscopically assisted anterior resection, anal tumor resection, and right inguinal lymph node resection were performed, and the histopathological examination of the resected primary and metastatic tumors confirmed similar findings of moderately differentiated adenocarcinoma, suggestive of metastasis of the rectal cancer to the anal region. In the next procedure, she had the liver lesions resected. This case suggested the importance of the careful examination of the anus during colonoscopy, or digital examination for the detection of anal metastasis. PMID- 27696278 TI - Why parametric measures are critical for understanding typical and atypical cognitive development. AB - Children's cognitive abilities improve significantly over childhood and adolescence. We know from behavioral research that core cognitive processes such as working memory and mental attention improve significantly across development. Functional magnetic resonance imaging (fMRI) allows for investigating the typically developing, living brain in action. In the last twenty years we have learned a great deal about brain correlates associated with how adults hold and manipulate information in mind, however, neurocognitive correlates across development remain inconsistent. We present developmental fMRI findings on cognitive processes such as working memory and mental attention and discuss methodological and theoretical issues in the assessment of cognitive limitations in the visual spatial and verbal domains. We also review data from typical and atypical development and emphasize the unique contribution parametric measures can make in understanding neurocognitive correlates of typical and atypical development. PMID- 27696279 TI - Diet and Complementary Medicine for Chronic Unexplained Nausea and Vomiting and Gastroparesis. AB - OPINION STATEMENT: Chronic nausea and vomiting, whether or not associated with gastroparesis, are among the most difficult symptoms to manage. Patients typically undergo extensive evaluation and empiric treatment often with suboptimal results. Conventional therapies may not produce adequate symptom relief or may cause unacceptable side effects. Thus, it is not surprising that patients report a negative impact on well-being, since the intermittent or constant occurrence of these symptoms are a source of anxiety as they impact social interactions and ability to work. Patients may seek complementary and alternative medicine (CAM), which may include acupuncture and herbal formulations, not only to manage nausea and vomiting, but also to remedy those symptoms associated with chronic illness, like insomnia and general fatigue. This chapter will review diet and different modalities of CAM to treat gastroparesis and chronic unexplained nausea and vomiting. PMID- 27696281 TI - Exposure Potential and Health Impacts of Indium and Gallium, Metals Critical to Emerging Electronics and Energy Technologies. AB - The rapid growth of new electronics and energy technologies requires the use of rare elements of the periodic table. For many of these elements, little is known about their environmental behavior or human health impacts. This is true for indium and gallium, two technology critical elements. Increased environmental concentrations of both indium and gallium create the potential for increased environmental exposure, though little is known about the extent of this exposure. Evidence is mounting that indium and gallium can have substantial toxicity, including in occupational settings where indium lung disease has been recognized as a potentially fatal disease caused by the inhalation of indium particles. This paper aims to review the basic chemistry, changing environmental concentrations, potential for human exposure, and known health effects of indium and gallium.

AB - Cadmium is a naturally-occurring element, and humans are exposed from cigarettes, food, and industrial sources. Following exposure, cadmium accumulates in the kidney and is slowly released into the urine, usually proportionally to the levels found in the kidneys. Cadmium levels in a single spot urine sample have been considered indicative of long-term exposure to cadmium; however, such a potentially exceptional biomarker requires careful scrutiny. In this review, we report good to excellent temporal stability of urinary cadmium (intraclass correlation coefficient 0.66-0.81) regardless of spot urine or first morning void sampling. Factors such as changes in smoking habits and diseases characterized by increased excretion of proteins may produce short-term changes in urinary cadmium levels. We recommend that epidemiologists use this powerful biomarker in prospective studies stratified by smoking status, along with thoughtful consideration of additional factors that can influence renal physiology and cadmium excretion. PMID- 27696283 TI - A multicenter phase 2 study of empirical low-dose liposomal amphotericin B in patients with refractory febrile neutropenia. AB - Invasive fungal infection (IFI) is a major life-threatening problem encountered by patients with hematological malignancies receiving intensive chemotherapy. Empirical antifungal agents are therefore important. Despite the availability of antifungal agents for such situations, the optimal agents and administration methods remain unclear. We conducted a prospective phase 2 study of empirical 1 mg/kg/day liposomal amphotericin B (L-AMB) in 80 patients receiving intensive chemotherapy for hematological malignancies. All enrolled patients were high-risk and had recurrent prolonged febrile neutropenia despite having received broad spectrum antibacterial therapy for at least 72 hours. Fifty-three patients (66.3 %) achieved the primary endpoint of successful treatment, thus exceeding the predefined threshold success rate. No patients developed IFI. The treatment completion rate was 73.8 %, and only two cases ceased treatment because of adverse events. The most frequent events were reversible electrolyte abnormalities. We consider low-dose L-AMB to provide comparable efficacy and improved safety and cost-effectiveness when compared with other empirical antifungal therapies. Additional large-scale randomized studies are needed to determine the clinical usefulness of L-AMB relative to other empirical antifungal therapies. PMID- 27696285 TI - What is This Image? 2016: Image 3 Result. PMID- 27696284 TI - Osteoporosis and Periodontitis. AB - Osteoporosis and periodontitis are both diseases characterized by bone resorption. Osteoporosis features systemic degenerative bone loss that leads to loss of skeletal cancellous microstructure and subsequent fracture, whereas periodontitis involves local inflammatory bone loss, following an infectious breach of the alveolar cortical bone, and it may result in tooth loss. Most cross sectional studies have confirmed the association of osteoporosis and periodontitis primarily on radiographic measurements and to a lesser degree on clinical parameters. Multiple shared risk factors include age, genetics, hormonal change, smoking, as well as calcium and vitamin D deficiency. Both diseases could also be risk factors for each other and have a mutual impact that requires concomitant management. Suggested mechanisms underlying the linkage are disruption of the homeostasis concerning bone remodeling, hormonal balance, and inflammation resolution. A mutual interventional approach is emerging with complex treatment interactions. Prevention and management of both diseases require interdisciplinary approaches and warrants future well-controlled longitudinal and interventional studies for evidence-based clinical guidelines. PMID- 27696286 TI - Radiation dose optimization for the bolus tracking technique in abdominal computed tomography: usefulness of real-time iterative reconstruction for monitoring scan. AB - The purpose of this study was to optimize the monitoring dose, obtained using the conventional filtered back projection (FBP) method and iterative reconstruction algorithms, for the bolus tracking technique. A phantom study was performed to assess the effect of the scan start time in patients grouped according to different body weights. An oval torso phantom was used for simulating the time enhancement curve of the bolus tracking technique. To reproduce image noise levels in the two body weight groups, the phantom diameter was adjusted with a water-equivalent material. The tube currents were 10, 20, 30, and 50 mA. The monitoring scan was performed with the conventional FBP method and real-time adaptive iterative dose reduction by three-dimensional processing (AIDR 3D). The results at different doses were compared with those at 50 mA. The volume computed tomography dose index was 1.31, 2.65, 3.93, and 6.56 mGy at tube currents of 10, 20, 30, and 50 mA, respectively. The scan start time, reconstructed using FBP, was significantly faster at 10 and 20 mA in group A (50-59 kg) and at 20 mA in group B (>=80 kg). The CT values in the region of interest could not be measured at 10 mA because of artifacts. With real-time AIDR 3D, both groups showed no significant differences between the measurements obtained at 30 or 20 mA and those obtained at 50 mA. Our study demonstrated that the real-time AIDR 3D algorithm improved the accuracy of the CT measurements with the bolus tracking technique. PMID- 27696287 TI - Molecular Dissection of Seedling Salinity Tolerance in Rice (Oryza sativa L.) Using a High-Density GBS-Based SNP Linkage Map. AB - BACKGROUND: Salinity is one of the many abiotic stresses limiting rice production worldwide. Several studies were conducted to identify quantitative trait loci (QTLs) for traits associated to salinity tolerance. However, due to large confidence interval for the position of QTLs, utility of reported QTLs and the associated markers has been limited in rice breeding programs. The main objective of this study is to construct a high-density rice genetic map for identification QTLs and candidate genes for salinity tolerance at seedling stage. RESULTS: We evaluated a population of 187 recombinant inbred lines (RILs) developed from a cross between Bengal and Pokkali for nine traits related to salinity tolerance. A total of 9303 SNP markers generated by genotyping-by-sequencing (GBS) were mapped to 2817 recombination points. The genetic map had a total map length of 1650 cM with an average resolution of 0.59 cM between markers. For nine traits, a total of 85 additive QTLs were identified, of which, 16 were large-effect QTLs and the rest were small-effect QTLs. The average interval size of QTL was about 132 kilo base pairs (Kb). Eleven of the 85 additive QTLs validated 14 reported QTLs for shoot potassium concentration, sodium-potassium ratio, salt injury score, plant height, and shoot dry weight. Epistatic QTL mapping identified several pairs of QTLs that significantly contributed to the variation of traits. The QTL for high shoot K+ concentration was mapped near the qSKC1 region. However, candidate genes within the QTL interval were a CC-NBS-LRR protein, three uncharacterized genes, and transposable elements. Additionally, many QTLs flanked small chromosomal intervals containing few candidate genes. Annotation of the genes located within QTL intervals indicated that ion transporters, osmotic regulators, transcription factors, and protein kinases may play essential role in various salt tolerance mechanisms. CONCLUSION: The saturation of SNP markers in our linkage map increased the resolution of QTL mapping. Our study offers new insights on salinity tolerance and presents useful candidate genes that will help in marker assisted gene pyramiding to develop salt tolerant rice varieties. PMID- 27696288 TI - Communities of endophytic microorganisms in different developmental stages from a local variety as well as transgenic and conventional isogenic hybrids of maize. AB - The diversity of endophytic microorganisms may change due to the genotype of the host plant and its phenological stage. In this study we evaluated the effect of phenological stage, transgenes and genetic composition of maize on endophytic bacterial and fungal communities. The maize populations were composed of a local variety named Rosado (RS) and three isogenic hybrids. One isogenic hybrid was not genetically modified (NGM). Another hybrid (Hx) contained the transgenes cry1F and pat (T1507 event), which provide resistance to insects of the order Lepidoptera and tolerance to the glufosinate-ammonium herbicide, respectively. The third hybrid (Hxrr) contained the transgene cp4 epsps (NK603 event) combined with the transgenes cry1F and pat (T1507 event), which allow tolerance to the Roundup Ready herbicide, besides the characteristics of Hx. Evaluation of the foliar tissue was done through PCR-DGGE analysis, with specific primers for bacteria and fungi within four phenological stages of maize. The endophytic bacteria were only clustered by phenological stages; the structure of the fungal community was clustered by maize genotypes in each phenological stage. The fungal community from the local variety RS was different from the three hybrids (NGM, Hx and Hxrr) within the four evaluated stages. In the reproductive stage, the fungal community from the two transgenic hybrids (Hx and Hxrr) were separated, and the Hxrr was different from NGM, in the two field experiments. This research study showed that the genetic composition of the maize populations, especially the presence of transgenes, is the determining factor for the changes detected in the endophytic fungal community of maize leaves. PMID- 27696289 TI - Optimization of substrate preparation for oyster mushroom (Pleurotus ostreatus) cultivation by studying different raw materials and substrate preparation conditions (composting: phases I and II). AB - In recent years, oyster mushroom (Pleurotus ostreatus) has become one of the most cultivated mushrooms in the world, mainly in Brazil. Among many factors involved in a mushroom production, substrate preparation is the most critical step, which can be influenced by composting management techniques. Looking forward to optimizing the substrate preparation process, were tested different composting conditions (7 and 14 days of composting with or without conditioning), potential raw materials (decumbens grass, brizantha grass and sugarcane straw) and nitrogen supplementation (with or without wheat bran) on oyster mushroom yield and biological efficiency (BE). The substrate composted for 7 days with conditioning showed higher yield and biological efficiency of mushroom (24.04 and 100.54 %, respectively). Substrates without conditioning (7 and 14 days of composting) showed smaller mushroom yield and biological efficiency. Among the raw materials tested, brizantha grass showed higher mushroom yield followed by decumbens grass, sugarcane straw and wheat straw (28.5, 24.32, 23.5 and 19.27 %, respectively). Brizantha grass also showed higher biological efficiency followed by sugarcane straw, decumbens grass and wheat straw (123.95, 103.70, 96.90 and 86.44 %, respectively). Supplementation with wheat bran improved yield and biological efficiency in all substrate formulations tested; thus, oyster mushroom yield and biological efficiency were influenced by substrate formulation (raw materials), supplementation and composting conditions.

A Population-Based Study. PMID- 27696292 TI - Erratum to: Clinical role of HER2 gene amplification and chromosome 17: a study on 154 IHC-equivocal cases of invasive breast carcinoma patients. PMID- 27696291 TI - MicroRNA-218 inhibits the proliferation, migration, and invasion and promotes apoptosis of gastric cancer cells by targeting LASP1. AB - The present study aims to investigate the effects of microRNA-218 (miR-218) on the proliferation, migration, invasion, and apoptosis of gastric cancer (GC) cells by targeting LIM and SH3 domain protein 1 (LASP1). The GC cells in the logarithmic phase were selected and divided into five groups: the blank group, negative control (NC) group, miR-218 inhibitors group, miR-218 inhibitors + siLASP1 group, and miR-218 mimics + siLASP1 group. The miR-218 expression in each group was also detected by qRT-PCR. The CCK8 assay, Transwell migration, and invasion assays and flow cytometry were performed to determine the effects of miR 218 on cell proliferation, migration, invasion, and apoptosis of GC cells. Western blotting was conducted to measure LASP1 protein expression in GC cells after transfection. The qRT-PCR revealed that the transfection of miR-218 mimics could upregulate the miR-218 expression, and the transfection of miR-218 inhibitors could downregulate the miR-218 expression in the GC cells. Compared with the blank and NC groups, the proliferation, migration, and invasion of GC cells were significantly reduced in the miR-218 mimics, miR-218 inhibitors + siLASP1, and miR-218 mimics + siLASP1 groups but enhanced in the miR-218 inhibitors group. Similarly, compared with the blank and NC groups, the cell apoptosis rates in the miR-218 mimics, miR-218 inhibitors + siLASP1, and the miR 218 mimics + siLASP1 groups were significantly increased, while the miR-218 inhibitors group had a lower apoptosis rate. In conclusion, these results indicate that miR-218 could inhibit the proliferation, migration, and invasion and promote apoptosis of GC cells by downregulating LASP1 expression. PMID- 27696293 TI - Reversion-inducing cysteine-rich protein with Kazal motifs and its regulation by glycogen synthase kinase 3 signaling in oral cancer. AB - The reversion-inducing cysteine-rich protein with Kazal motifs (RECK) and glycogen synthase kinase (GSK3) are novel tumor suppressors, and emerging evidence has suggested their active role in oral cancer pathogenesis. In the present study, 112 human samples, including 55 fresh samples of 14 adjacent normal tissues, 25 noninvasive oral tumors, and 18 invasive tumors, were included. The messenger RNA (mRNA) expression, protein expression, and promoter methylation of the RECK gene, as well as the expression of GSK3beta, phospho/total beta-catenin, and c-myc, were measured by RT-PCR, bisulphate modification-PCR, immunohistochemistry, and Western blot analysis. Additionally, ectopic expression of in/active GSK3beta was performed in cell culture experiments. This study provided information on the progressive silencing of RECK gene expression at the protein and mRNA levels paralleled with promoter hypermethylation at various stages of oral tumor invasion. RECK expression and the hypermethylation of the RECK gene promoter were negatively and positively correlated with pS9GSK3beta/c-myc expression, respectively. Further, a negative trend of RECK protein expression with nuclear beta-catenin expression was observed. Induced expression of active GSK3beta reversed the RECK silencing in SCC9 cells. Collectively, our results demonstrated that the silencing of the RECK gene, possibly regulated by the GSK3beta pathway, is an important event in oral cancer invasion and this pathway could be exploited for therapeutic interventions. PMID- 27696294 TI - Hepatitis C virus promotes hepatocellular carcinogenesis by targeting TIPE2, a new regulator of DNA damage response. AB - Infection of hepatitis C virus (HCV) is associated with primary hepatocellular carcinoma (HCC). However, its underlying molecular mechanisms remain enigmatic. Tumor necrosis factor-alpha-induced protein 8-like 2 (TIPE2), a new negative regulator of immunity, plays significant roles in modulating inflammation and tumorigenesis. We hypothesized that TIPE2 might be involved in the development of HCV-induced HCC. To test this hypothesis, the expression of TIPE2 was determined by Western blot in the tumor and pericarcinomatous tissues collected from ten HCV positive HCC patients; the interaction between TIPE2 and HCV-encoded non structural proteins was analyzed by immunoprecipitation and immunofluorescence assays, and tumorigenesis and its mechanisms were studied in cell models and nude mice. Our results demonstrated that the expression of TIPE2 was significantly reduced in HCC tissues compared to that in the paracarcinoma tissues. HCV-encoded non-structural protein NS5A could specifically interact with TIPE2 and induce its degradation. Downregulation of TIPE2 by shRNA in cell lines increased genomic DNA damage and promoted cell colony formation in vitro and tumorigenesis in nude mice. In contrast, overexpression of TIPE2 had an opposite effect. Downregulation of TIPE2 by NS5A is associated with genomic DNA instability and HCV-induced HCC development. Thus, TIPE2 may be a new therapeutic target for the treatment of HCV associated HCC. PMID- 27696295 TI - Serum microRNA-21 expression as a prognostic and therapeutic biomarker for breast cancer patients. AB - MiRNA-21 is recognized as the main active candidate and high expression in many solid tumors consequential cell proliferation, differentiation, apoptosis, and closely related to metastasis of disease. The study aimed to evaluate the serum miRNA-21 expression and therapy outcome in breast cancer patients and cell lines. Seventy-five histopathologically confirmed newly diagnosed breast cancer patients were included in the study; before and after therapy, patient's blood sample were collected and analyzed for serum microRNA-21 expression by quantitative real-time PCR. In patients, 8.9 mean fold increased microRNA-21 expression was observed compared to controls. Increased expression was found to be associated with advanced stage (11.72-fold), lymph node involvement (11.12-fold), and distant metastases (20.17-fold). After treatment significant decrease in miRNA-21 expression was observed and found to be significant (p < 0.0001). Patients treated with neoadjuvant therapy had significant impact on miRNA-21 suppression and found to be significantly associated with different clinicopathological features of patients. Increased miRNA-21 expression was also found to be significantly associated with poor survival of breast cancer patients (p = 0.002). MicroRNA-21 expression could be used as promising predictive indicators for breast cancer prognosis. MicroRNA-21 over-expression was associated with response to neoadjuvant therapy and may perhaps be considered as primary treatment choice. PMID- 27696296 TI - Periostin promotes the chemotherapy resistance to gemcitabine in pancreatic cancer. AB - Pancreatic ductal adenocarcinoma (PDAC) ranks fourth among cancer-related deaths. The nucleoside analog gemcitabine has been the cornerstone of adjuvant chemotherapy in PDAC for decades. However, gemcitabine resistance develops within weeks of chemotherapy initiation, which might be intrinsic to cancer cells and influenced by tumor microenvironment. Recently, pancreatic stellate cells (PSCs) have greatly increased our attention on tumor microenvironment-mediated drug resistance. Periostin is exclusively overexpressed in PSCs and the stroma of PDAC creating a tumor-supportive microenvironment in the pancreas. However, whether periostin contributed to chemoresistance in PDAC remains unknown. Therefore, we focused on the role of periostin in PDAC by observing the effects of silencing this gene on gemcitabine resistance in vitro and in vivo aiming to explore the possible molecular mechanism. In this study, the pancreatic cancer cell (PCC) proliferation and apoptosis were assayed to investigate the sensitivity to gemcitabine after silencing periostin. We provide the evidence that periostin not only drives the carcinogenic process itself but also significantly associated with gemcitabine-induced apoptosis. These findings collectively indicated that periostin increases the chemoresistance to gemcitabine. Thus, targeting periostin might offer a new opportunity to overcome the gemcitabine resistance of PDAC. PMID- 27696297 TI - How the reference values for serum parathyroid hormone concentration are (or should be) established? AB - Well-validated reference values are necessary for a correct interpretation of a serum PTH concentration. Establishing PTH reference values needs recruiting a large reference population. Exclusion criteria for this population can be defined as any situation possibly inducing an increase or a decrease in PTH concentration. As recommended in the recent guidelines on the diagnosis and management of asymptomatic primary hyperparathyroidism, PTH reference values should be established in vitamin D-replete subjects with a normal renal function with possible stratification according to various factors such as age, gender, menopausal status, body mass index, and race. A consensus about analytical/pre analytical aspects of PTH measurement is also needed with special emphasis on the nature of the sample (plasma or serum), the time and the fasting/non-fasting status of the blood sample. Our opinion is that blood sample for PTH measurement should be obtained in the morning after an overnight fast. Furthermore, despite longer stability of the PTH molecule in EDTA plasma, we prefer serum as it allows to measure calcium, a prerequisite for a correct interpretation of a PTH concentration, on the same sample. Once a consensus is reached, we believe an important international multicentre work should be performed to recruit a very extensive reference population of apparently healthy vitamin D-replete subjects with a normal renal function in order to establish the PTH normative data. Due to the huge inter-method variability in PTH measurement, a sufficient quantity of blood sample should be obtained to allow measurement with as many PTH kits as possible. PMID- 27696298 TI - Timing of the negative effects of trastuzumab on cardiac mechanics after anthracycline chemotherapy. AB - Trastuzumab (TZB) has been shown to be extremely effective in breast cancer patients over-expressing HER-2, but careful cardiac monitoring is required when TZB is administered with anthracyclines, since the combination can increase its toxicity. Myocardial deformation indexes associated with speckle tracking echocardiography (STE) have proven to be very sensitive in identifying early myocardial dysfunction. An observational, prospective study was designed to assess TZB-induced cardiac damage using STE in patients with HER-2 positive breast cancer who had been sequentially treated with TZB following epirubicin (EPI). Conventional echocardiographic parameters and STE deformation indexes (longitudinal, radial, and circumferential strain/strain rate and apical rotation) were analyzed at baseline, after each EPI treatment, and 1 week after every other dose of TZB administration until 1 year follow up, in order to focus on the timing and extent of myocardial impairment. In the forty-five enrolled patients, a reduction in subendocardial function after EPI treatment was observed by a significant impairment of the global longitudinal strain/strain rate (GLS/SR), while a significant increase in the activity of the subepicardial fibers was highlighted by an increase in apical rotation. After the second TZB dose, a sudden reduction of the apical rotation was seen, together with circumferential and radial strain/SR. Most importantly, the extent to which the apical rotation increased and decreased was found to strictly correlate with the GLS reduction at follow up. We found that after EPI therapy, subendocardial function was impaired, even while a compensatory increase in apical rotation occurred. Following TZB treatment, we observed impairment in apical rotation, which seems to be the first sign of global LV dysfunction predicting GLS reduction found at the end of treatment. PMID- 27696299 TI - Treatment-Related Progressive Multifocal Leukoencephalopathy in Multiple Sclerosis: A Comprehensive Review of Current Evidence and Future Needs. AB - Progressive multifocal leukoencephalopathy (PML) is a rare opportunistic infection of the central nervous system caused by the John Cunningham virus (JCV) that has been associated with therapeutic immunosuppression in patients with multiple sclerosis (MS). So far, more than 600 cases of PML have been reported in association with natalizumab administration. There have also been confirmed cases of PML in individuals who received fingolimod and dimethyl fumarate without previous natalizumab treatment. The new licensed disease-modifying therapies for MS carry the risk of immunosuppressant and so of JCV reactivation. Various factors have been identified with increased risk of developing PML, including a positive JCV serology, natalizumab administration for >2 years, and prior use of immunosuppressive agents. Clinicians can employ such tools for patients' risk stratification, but the incidence of PML among patients receiving natalizumab therapy has not changed. In this review we outline the current state of understanding of PML pathogenesis and patients' risk stratification. The landscape of MS is dramatically changing and knowledge of the side effects of the licensed therapies is imperative to enable optimal decision making. PMID- 27696301 TI - Systematical investigation of a combinative particle size reduction technology for production of resveratrol nanosuspensions. AB - Nanosizing is frequently used as formulation approach to increase the bioavailability of poorly water-soluble drugs. However, standard size reduction processes can be relatively time-consuming. It was found that the modification of the physical properties of a starting material by means of spray-drying can be used to improve the effectiveness of a subsequently performed high pressure homogenization. Such a process belongs to the combinative particle size reduction methods and is also referred to as H 42 process. Based on previous studies, it was hypothesized that the improved efficiency was a result of reduced crystallinity of the modified drug. The present study was conducted in order to asses this hypothesis in a systematical manner by applying design of experiment (DoE) principles. Resveratrol was selected as model compound for this study. It was processed by both standard high pressure homogenization and by a combinative particle size reduction process (the H42 process). An optimized resveratrol/surfactant ratio for the spray-dried intermediate was identified by using the response-surface methodology. The optimization led to a nanosuspension with a mean particle size of 192 nm, which is much smaller than the mean particle size of 569 nm when standard high pressure homogenization was used. Both predominately crystalline and predominately amorphous solids resulted from the spray-drying process. In contrast to the initial hypothesis, the smallest particle sizes were achieved by processing predominately crystalline intermediate with high pressure homogenization. PMID- 27696302 TI - Electrosprayed Janus Particles for Combined Photo-Chemotherapy. AB - This work is a proof of concept study establishing the potential of electrosprayed Janus particles for combined photodynamic therapy-chemotherapy. Sub-micron-sized particles of polyvinylpyrrolidone containing either an anti cancer drug (carmofur) or a photosensitiser (rose bengal; RB), and Janus particles containing both in separate compartments were prepared. The functional components were present in the amorphous form in all the particles, and infrared spectroscopy indicated that intermolecular interactions formed between the different species. In vitro drug release studies showed that both carmofur and RB were released at approximately the same rate, with dissolution complete after around 250 min. Cytotoxicity studies were undertaken on model human dermal fibroblasts (HDF) and lung cancer (A549) cells, and the influence of light on cell death explored. Formulations containing carmofur as the sole active ingredient were highly toxic to both cell lines, with or without a light treatment. The RB formulations were non-toxic to HDF when no light was applied, and with photo-treatment caused large amounts of cell death for both A549 and HDF cells. The Janus formulation containing both RB and carmofur was non-toxic to HDF without light, and only slightly toxic with the photo-treatment. In contrast, it was hugely toxic to A549 cells when light was applied. The Janus particles are thus highly selective for cancer cells, and it is hence proposed that such electrosprayed particles containing both a chemotherapeutic agent and photosensitiser have great potential in combined chemotherapy/photodynamic therapy. PMID- 27696300 TI - Risk-Benefit Profile of Direct-Acting Oral Anticoagulants in Established Therapeutic Indications: An Overview of Systematic Reviews and Observational Studies. AB - Since 2008, the direct-acting oral anticoagulants (DOACs) have expanded the therapeutic options of cardiovascular diseases with recognized clinical and epidemiological impact, such as non-valvular atrial fibrillation (NVAF) and venous thromboembolism (VTE), and also in the preventive setting of orthopedic surgical patients. The large body of evidence, not only from pivotal clinical trials but also from 'real-world' postmarketing observational findings (e.g. analytical epidemiological studies and registry data) gathered to date allow for a first attempt at verifying a posteriori whether or not the pharmacological advantages of the DOACs actually translate into therapeutic innovation, with relevant implications for clinicians, regulators and patients. This review aims to synthesize the risk-benefit profile of DOACs in the aforementioned consolidated indications through an 'evidence summary' approach gathering the existent evidence-based data, particularly systematic reviews with meta-analyses of randomized controlled trials, as well as observational studies, comparing DOACs with vitamin K antagonists. Clinical evidence will be discussed and compared with major international guidelines to identify whether an update is needed. Controversial clinically relevant safety issues will be also examined in order to highlight current challenges and unsettled questions (e.g. actual bleeding risk in susceptible populations). It is anticipated that the large number of publications on NVAF or VTE (44 systematic reviews with meta-analyses and 12 observational studies retained in our analysis) suggests the potential existence of overlapping studies and calls for common criteria to qualitatively and quantitatively assess discordances, thus guiding future research.

PMID- 27696303 TI - MALAT1 Long Non-coding RNA Expression in Thyroid Tissues: Analysis by In Situ Hybridization and Real-Time PCR. AB - Long non-coding RNAs (lncRNAs) are important for transcription and for epigenetic or posttranscriptional regulation of gene expression and may contribute to carcinogenesis. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), an lncRNA involved in the regulation of the cell cycle, cell proliferation, and cell migration, is known to be deregulated in multiple cancers. Here, we analyzed the expression of MALAT1 on 195 cases of benign and malignant thyroid neoplasms by using tissue microarrays for RNA in situ hybridization (ISH) and real-time PCR. MALAT1 is highly expressed in normal thyroid (NT) tissues and thyroid tumors, with increased expression during progression from NT to papillary thyroid carcinomas (PTCs) but is downregulated in poorly differentiated thyroid cancers (PDCs) and anaplastic thyroid carcinomas (ATCs) compared to NT. Induction of epithelial to mesenchymal transition (EMT) by transforming growth factor (TGF) beta in a PTC cell line (TPC1) led to increased MALAT1 expression, supporting a role for MALAT1 in EMT in thyroid tumors. This is the first ISH study of MALAT1 expression in thyroid tissues. It also provides the first piece of evidence suggesting MALAT1 downregulation in certain thyroid malignancies. Our findings support the notion that ATCs may be molecularly distinct from low-grade thyroid malignancies and suggest that MALAT1 may function both as an oncogene and as a tumor suppressor in different types of thyroid tumors. PMID- 27696305 TI - Identifying the role of reactive oxygen species (ROSs) in Fusarium solani spores inactivation. AB - The inactivation mechanism of photocatalytic disinfectants on bacteria is well known. In contrast, the potential inactivation of fungal spores by visible-light induced photocatalysis has been recognized, but the inactivation mechanism is poorly understood. We hypothesize that photocatalytically generated reactive oxygen species (ROSs) are directly involved in this mechanism. To test this hypothesis, we identified the roles of ROSs in the inactivation of Fusarium solani spores. As the photocatalysts, we doped TiO2 with 3 typical dopants, forming Ag/TiO2, N/TiO2 and Er3+:YAlO3/TiO2. The Ag/TiO2 photocatalysis was dominated by H2O2, with the longest lifetime among the investigated ROSs. Ag/TiO2 photocatalysis yielded almost 100 % inactivation efficiency and preserved the cell-wall shape of the spores, thus minimizing the biomolecule leakage. Er3+:YAlO3/TiO2 was dominated by h+ ROSs, yielding an inactivation efficiency of 91 %; however, the severe leakage released large numbers of molecular bio products. Severe damage to the cell walls by the h+ species was confirmed in micrograph observations. Subsequent to cell wall breakage, the Er3+:YAlO3/TiO2 nanoparticles entered the spore cells and directly oxidized the intracellular material. The N/TiO2 photocatalysis, with *O2- dominated ROSs, delivered intermediate performance. In conclusion, photocatalysts that generate H2O2 dominated ROSs are most preferred for spore inactivation. PMID- 27696306 TI - Assessing the Potential Cost-Effectiveness of Microneedle Patches in Childhood Measles Vaccination Programs: The Case for Further Research and Development. AB - OBJECTIVE: Currently available measles vaccines are administered by subcutaneous injections and require reconstitution with a diluent and a cold chain, which is resource intensive and challenging to maintain. To overcome these challenges and potentially increase vaccination coverage, microneedle patches are being developed to deliver the measles vaccine. This study compares the cost effectiveness of using microneedle patches with traditional vaccine delivery by syringe-and-needle (subcutaneous vaccination) in children's measles vaccination programs. METHODS: We built a simple spreadsheet model to compute the vaccination costs for using microneedle patch and syringe-and-needle technologies. We assumed that microneedle vaccines will be, compared with current vaccines, more heat stable and require less expensive cool chains when used in the field. We used historical data on the incidence of measles among communities with low measles vaccination rates. RESULTS: The cost of microneedle vaccination was estimated at US$0.95 (range US$0.71-US$1.18) for the first dose, compared with US$1.65 (range US$1.24-US$2.06) for the first dose delivered by subcutaneous vaccination. At 95 % vaccination coverage, microneedle patch vaccination was estimated to cost US$1.66 per measles case averted (range US$1.24-US$2.07) compared with an estimated cost of US$2.64 per case averted (range US$1.98-US$3.30) using subcutaneous vaccination. CONCLUSIONS: Use of microneedle patches may reduce costs; however, the cost-effectiveness of patches would depend on the vaccine recipients' acceptability and vaccine effectiveness of the patches relative to the existing conventional vaccine-delivery method. This study emphasizes the need to continue research and development of this vaccine-delivery method that could boost measles elimination efforts through improved access to vaccines and increased vaccination coverage. PMID- 27696307 TI - Optimal Transducer Level for Atrial and Pulmonary Arterial Pressure Measurement in Patients with Functional Single Ventricle. AB - This study aimed to investigate the optimal transducer level for accurate measurement of atrial and pulmonary arterial pressures in the supine position for patients with functional single ventricle. Contrast-enhanced chest computed tomographic images of 108 patients who underwent either the bidirectional cavopulmonary shunt (BCPS) placement or the Fontan procedure were reviewed. Vertical distances from the skin of the back to the uppermost levels of fluid in the single atrium or the pulmonary artery confluence and their ratios to the greatest anteroposterior (AP) diameter of the thoracic cage were determined. In patients who underwent BCPS, the ratios of the uppermost levels of blood in the atrium and pulmonary artery confluence to the greatest AP diameter of the thorax were 76.0 +/- 8.1 and 56.3 +/- 5.5 %, respectively. The distance (mm) between these two levels was calculated as 24.2 + 0.31 * age (years) (r 2 = 0.08, P < 0.03). In patients who underwent the Fontan procedure, the ratios were 79.3 +/- 10.0 and 58.3 +/- 5.8 %, respectively. The distance (mm) between these two levels was calculated as 31.1 + 0.44 * age (years) (r 2 = 0.05, P < 0.11). The optimal transducer levels for measuring atrial and pulmonary arterial pressures in the supine position are 75-80 and 55-60 % of the AP diameter of the thorax, respectively, in patients with functional single ventricle. We should consider the difference of the pressure when atrial and pulmonary arterial pressures were measured with the same level of transducers. PMID- 27696308 TI - MicroRNA-200c modulates DUSP-1 expression in diabetes-induced cardiac hypertrophy. AB - Mitogen-activated protein kinases (MAPKs) (ERK1/2, JNK, and p38) are upregulated in diabetic cardiomyopathy (DCM). Dual-specific phosphatase-1 (DUSP-1) has been reported to regulate the activity of MAPKs in cardiac hypertrophy; however, the role of DUSP-1 in regulating MAPKs activity in DCM is not known. MicroRNAs have been reported to regulate the expression of several genes in hypertrophied failing hearts. However, little is known about the microRNAs regulating DUSP-1 expression in diabetes-related cardiac hypertrophy. In the present study, we investigated the role of DUSP-1 and miR-200c in diabetes-induced cardiac hypertrophy. DCM was induced in Wistar rats by low-dose Streptozotocin high-fat diet for 12 weeks. Cardiac expression of ERK, p-38, JNK, DUSP-1, miR-200c, and hypertrophy markers (ANP and beta-MHC) was studied in DCM in control rats and in high-glucose (HG)-treated rat neonatal cardiomyocytes. miR-200c inhibition was performed to validate DUSP-1 as target. A significant increase in phosphorylated ERK, p38, and JNK was observed in DCM model and in HG-treated cardiomyocytes (p < 0.05). Expression of DUSP-1 was significantly decreased in diabetes group and in HG-treated cardiomyocytes (p < 0.05). Increased expression of miR-200c was observed in DCM model and in HG-treated cardiomyocytes (p < 0.05). Inhibition of miR-200c induces the expression of the DUSP-1 causing decreased expression of phosphorylated ERK, p38, and JNK and attenuated cardiomyocyte hypertrophy in HG treated cardiomyocytes. miR-200c plays a role in diabetes-associated cardiac hypertrophy by modulating expression of DUSP-1. PMID- 27696309 TI - Epidermal growth factor receptor targeting alters gene expression and restores the adhesion function of cancerous cells as measured by single cell force spectroscopy. AB - Loss of cell-cell adhesion function is a common characteristic of many human epithelial carcinomas that is frequently due to loss of E-cadherin expression. In cancer progression, loss of E-cadherin is associated with invasion and metastasis potential, hence restoration of its function may contribute to the metastasis inhibition. This study examined effect of Epidermal Growth Factor Receptor (EGFR/Her1) blockade on the E-cadherin expression, cellular adherence, and cell elasticity in two human epithelial cancer cell lines, MCF7 and A431. EGFR blocking agents as antibodies or small molecules target EGFR directly. Furthermore, due to intracellular signaling pathways they influence cell behavior and activities. The idea here is to investigate the effect of reduced activity of this signaling pathway using anti-EGFR Antibody (Cetuximab) and tyrosine kinase inhibitor (Lapatinib) on cell-cell adhesion and cell mechanical properties. Real Time PCR analysis demonstrated that treatment of cells with considered drugs increased the expression of E-cadherin gene among samples. The atomic force microscopy-based single cell force spectroscopy technique was used to measure adhesive force of cancerous cells. Results indicated that inhibition of EGFR activity elevated cell-cell adhesion force, accompanied by stiffening of the cell bodies. In summary, Cetuximab and Lapatinib have been found to mediate cell-cell adhesion by restoration of E-cadherin expression and function. Our data suggest possible therapeutic potential for inhibition of metastasis via the blockade of EGFR signaling. PMID- 27696310 TI - Chemoprotective and chemosensitizing properties of selenium nanoparticle (Nano Se) during adjuvant therapy with cyclophosphamide in tumor-bearing mice. AB - Cyclophosphamide (CP) is one of the widely used anticancer agents; however, it has serious deleterious effects on normal host cells due to its nonspecific action. The essential trace element Selenium (Se) is suggested to have chemopreventive and chemotherapeutic efficacy and currently used in pharmaceutical formulations. Previous report had shown Nano-Se could protect CP induced hepatotoxicity and genotoxicity in normal Swiss albino mice; however, its role in cancer management is still not clear. The aim of present study is to investigate the chemoprotective efficacy of Nano-Se against CP-induced toxicity as well as its chemoenhancing capability when used along with CP in Swiss albino mice against Ehrlich's ascites carcinoma (EAC) cells. CP was administered (25 mg/kg b.w., i.p.) and Nano-Se was given (2 mg Se/kg b.w., p.o.) in concomitant and pretreatment schedule. Increase levels of serum hepatic marker, hepatic lipid peroxidation, DNA damage, and chromosomal aberration in CP-treated mice were significantly (P < 0.05) reversed by Nano-Se. The lowered status of various antioxidant enzymes in tumor-bearing mice after CP treatment was also effectively increased by Nano-Se. Administration of Nano-Se along with CP caused a significant reduction in tumor volume, packed cell volume, viable tumor cell count, and increased the survivability of the tumor-bearing hosts. The results suggest that Nano-Se exhibits significant antitumor and antioxidant effects in EAC-bearing mice. The potential for Nano-Se to ameliorate the CP-evoked toxicity as well as to improve the chemotherapeutic effect could have beneficial implications for patients undergoing chemotherapy with CP. PMID- 27696311 TI - Effectiveness of minimally invasive surgical procedures in the acceleration of tooth movement: a systematic review and meta-analysis. AB - OBJECTIVE: The objective of this study was to assess systematically the available scientific evidence relating the efficiency of minimally invasive surgical procedures in accelerating orthodontic tooth movement and the adverse effects associated with these procedures. METHODS: Electronic search of these databases CENTRAL, EMBASE, Scopus, PubMed, Web of Science, Google Scholar Beta, Trip, OpenGrey and PQDT OPEN was performed (last updated January 2016). The reference lists of the included studies were hand searched. Unpublished literature and ongoing studies were also checked electronically through ClinicalTrials.gov and (ICTRP). Randomized controlled trials (RCTs) with patients who received minimally invasive surgical procedures combined with fixed orthodontic appliances compared with conventional treatment were included. Cochrane's risk of bias tool was used to assess risk of bias. RESULTS: Four RCTs (61 patients) and nine ongoing protocols were included in this review. Only three RCTs were suitable for quantitative synthesis. Higher tooth movement rate was found with the minimally invasive surgical procedures by a weighted mean difference of 0.65 mm for 1 month of canine retraction (WMD = 0.65: 95 % CI (0.54, 0.76), p < 0.001) and by a weighted mean difference 1.41 mm for 2 months (WMD = 1.41: 95 % CI (0.81, 2.01), p < 0.001). No adverse effects associated with these procedures were reported. CONCLUSIONS: There is limited available evidence about the effectiveness of minimally invasive surgically accelerated orthodontics (MISAO). Although the current review indicated that MISAO can help in accelerating canine retraction, further research in this domain should be performed before it can be recommended in everyday clinical practice. PMID- 27696313 TI - ? PMID- 27696312 TI - Influence of maxillary posterior dentoalveolar discrepancy on angulation of maxillary molars in individuals with skeletal open bite. AB - BACKGROUND: The aim of this study was to determine the effect of the maxillary posterior dentoalveolar discrepancy (MPDD) on the angulation of maxillary molars in open bite subjects. METHODS: Pre-treatment lateral cephalograms of 90 young adults with skeletal open bite were examined. The sample initially included six groups categorized according to MPDD condition (present or absent) and sagittal skeletal facial growth patterns (classes I, II, or III). Then, the sample was separated into two groups according to MPDD (present = 50, absent = 40). When the eruption of the maxillary third molar was apparently blocked by the presence of an erupted second molar, a MPDD was considered. Maxillary molar angulation was measured. Independent T test was performed to determine differences between the groups considering MPDD condition. Principal component analysis (PCA) and multivariate analysis (MANCOVA) test were also developed. RESULTS: A decreased molar angulation was found in all groups with MPDD (overall p < 0.001, class I-p < 0.001, class II-p < 0.001, and class III-p < 0.05). The maxillary first and second molars angulations were lower between approximately 7 degrees and 14 degrees in cases with posterior discrepancy. The PCA was used to reduce the number of initial cephalometric variables; thereafter, a MANCOVA test was applied. Significance was only found for MPDD (p < 0.001), APDI (p = 0.001), and ratio (A'6'/A'P') (p = 0.026) for maxillary first molar angulation and APDI (p = 0.011) and MPDD (p < 0.001) for maxillary second molar angulation. CONCLUSIONS: The MPDD generates a major mesial displacement of the second and first molar roots with a concurrent simultaneous distal angulation of the associated crowns in individuals with skeletal open bite. PMID- 27696314 TI - [Lymphadenitis and systemic lupus erythematosus]. AB - A 25-year-old Caucasian female patient presented with fever and cervical lymphadenopathy. Laboratory findings showed elevated signs of inflammation, elevated ANA titer and strongly positive anti-dsDNA antibodies. The histopathology of the lymph nodes revealed distinct features of Kikuchi-Fujimoto disease, a benign, self-limiting lymphadenopathy that typically affects young Asian females. In the literature a coincidental occurrence of Kikuchi-Fujimoto disease and systemic lupus erythematosus (SLE) is well documented. We hypothesized a simultaneous occurrence of both diseases because of the typical antibodies and arthralgia. PMID- 27696315 TI - Methylophaga and Hyphomicrobium can be used as target genera in monitoring saline water methanol-utilizing denitrification. AB - Which bacterial taxonomic groups can be used in monitoring saline water methanol utilizing denitrification and whether nitrate is transformed into N2 in the process are unclear. Therefore, methylotrophic bacterial communities of two efficiently functioning (nitrate/nitrite reduction was 63-96 %) tropical and cool seawater reactors at a public aquarium were investigated with clone library analysis and 454 pyrosequencing of the 16S rRNA genes. Transformation of nitrate into N2 was confirmed using 15N labeling in incubation of carrier material from the tropical reactor. Combining the data with previous study results, Methylophaga and Hyphomicrobium were determined to be suitable target genera for monitoring the function of saline water methanol-fed denitrification systems. However, monitoring was not possible at the single species level. Interestingly, potential nitrate-reducing methylotrophs within Filomicrobium and closely related Fil I and Fil II clusters were detected in the reactors suggesting that they also contributed to methylotrophic denitrification in the saline environment. PMID- 27696316 TI - [Regional geriatric care concept in the District of Lippe : Structural effects and network formation in the case management-based model project]. AB - BACKGROUND: Regional planning of healthcare requires special consideration for the complex needs of elderly, multimorbid people living in a domestic environment. In the District of Lippe, a hospital (Klinikum Lippe) and network of ambulatory care physicians (Arztenetz Lippe) developed and tested a geriatric care network based on case management for geriatric patients living in a domestic environment. MATERIAL AND METHODS: The establishment of the geriatric care network (e.g. promoting networking acceptance and implementation) was formatively evaluated, e. g. with qualitative methods. Data were acquired by guideline-based interviews with experts and analyzed by qualitative content analysis according to Mayring. RESULTS: Structural effects included forming a cross-sectoral and interdisciplinary network for a functioning care network and a geriatric care pathway. The practical work of case managers (CM) is essential for communication with patients, family members and care providers as well as integrating providers into the network. A critical factor was working together with general practitioners and the close cooperation with the hospital's department of geriatric. The quality of care is improved because of exchange of information between sectors and continuity in the course of care. CONCLUSION: In the District of Lippe the quality of care was improved and structures of care were integrated by the network according to the needs of the target group. The integrative perspective was achieved in particular by the geriatric care pathway and integration of providers into the communication and care process; however, the scope of this care model could not be extended into routine care due to the rigid and subdivided health care system. PMID- 27696317 TI - Left Atrial Appendage Closure for Stroke Prevention in Atrial Fibrillation. AB - PURPOSE OF REVIEW: Anticoagulant therapy effectively reduces the incidence of stroke in patients with atrial fibrillation (AF) but is underutilized and frequently contraindicated. The left atrial appendage (LAA) is the primary site of thrombus formation in AF patients. Surgical and percutaneous appendage closure has been evaluated as a site-specific therapy to reduce systemic thromboembolism. RECENT FINDINGS: We will review LAA closure techniques, examine recent outcome data, and discuss the indications for, and potential complications of, each approach. Randomized data examining surgical LAA closure and epicardial closure with the LARIAT device are lacking. High quality, randomized data supports the efficacy of the WATCHMAN device for stroke prevention in patients with AF. PMID- 27696319 TI - Coronary Computed Tomography Angiography for Screening in Patients with Diabetes: Can Enhanced Detection of Subclinical Coronary Atherosclerosis Improve Outcome? AB - PURPOSE OF REVIEW: It is well known that there is a very high risk of cardiovascular complications among diabetic patients. In spite of all efforts at aggressive control of diabetes and its complications, the incidence of cardiovascular morbidity and mortality remains high, including in patients with no prior symptoms, underscoring a possible advantage for appropriate screening of asymptomatic patients for the presence of obstructive coronary artery disease (CAD). In this article, we sought primarily to review the results of studies designed to evaluate a possible role of coronary computed tomography angiography (CCTA) in the screening of asymptomatic diabetic patients for possible obstructive CAD. RECENT FINDINGS: Our review of current literature indicates that there is still no method of CAD screening identified that has been shown to reduce the cardiovascular risk of asymptomatic diabetic patients. Therefore, the utility and value of screening for CAD in asymptomatic diabetic patients remains controversial. CCTA screening has shown promise and has been demonstrated to predict future risk, but as yet has not demonstrated improvement in the outcomes of these high-risk patients. At our present state of knowledge, aggressive risk factor reduction appears to be the most important primary prevention strategy for all asymptomatic high-risk diabetic patients. However, there remains a great need for better and more sensitive and specific screening methods, as well as more effective treatments that may allow us to more accurately target diabetic patients who really are at high risk. Further large randomized and well controlled clinical trials may be necessary to determine whether screening for CAD can reduce cardiovascular event rates in patients with diabetes. PMID- 27696320 TI - Effect of Gelatin-Stabilized Copper Nanoparticles on Catalytic Reduction of Methylene Blue. AB - The synthesis of copper nanoparticles was carried out with gelatin as a stabilizer by reducing CuSO4.5H2O ions using hydrazine. Ascorbic acid and aqueous NaOH were also used as an antioxidant and pH controller, respectively. The effects of NaOH, hydrazine, and concentration of gelatin as stabilizer were studied. The synthesized copper nanoparticles were characterized by UV-vis spectroscopy, XRD, zeta potential measurements, FTIR, EDX, FESEM, and TEM. The formation of CuNPs@Gelatin is initially confirmed by UV-vis spectroscopic analysis with the characteristic band at 583 nm. XRD and TEM reports revealed that CuNPs@Gelatin (0.75 wt.%) is highly crystalline and spherical in shape with optimum average size of 4.21 +/- 0.95 nm. FTIR studies indicated the presence of amide group on the surface of the CuNPs indicating the stability of CuNPs which is further supported by zeta potential measurements with the negative optimum value of -37.90 +/- 0.6 mV. The CuNPs@G4 showed a good catalytic activity against methylene blue (MB) reduction using NaBH4 as a reducing agent in an aqueous solution. The best enhanced properties of CuNPs@G4 were found for the 0.75 wt.% gelatin concentration. Thermodynamic parameters (DeltaH and DeltaS) indicate that under the studied temperature, the reduction of MB by CuNPs@G4 is not feasible and had endothermic in nature. PMID- 27696318 TI - Statin Adherence: Does Gender Matter? AB - PURPOSE OF REVIEW: Cardiovascular disease (CVD) continues to be the leading cause of death for men and women in the USA. Statins have contributed significantly to noted declines in cardiovascular-related mortality in the last decade; however, the benefit of statins is inequitable across genders. Women continue to be less likely to take statins and to meet target LDL goals than men. As a possible contributing factor to this disparity, we explore the evidence for gender-based differences in provision of, and adherence to statins. RECENT FINDINGS: Compared with men, women are less likely to adhere to statins. Potential reasons for this gender difference in use of statins can be observed across all phases of adherence including both intentional and unintentional non-adherence. Notable gender-specific contributing factors for statin non-adherence include decreased provider and patient awareness of CVD risk among women, higher risk of statin intolerance among women, and competing demands associated with family caregiving responsibilities. Similar to limitations in the broader CVD literature, there is inadequate inclusion of gender-specific analyses in statin-related trials. Gender based disparities in statin adherence can be linked to both provider level, psychosocial, and medication intolerance factors. Interventions designed to improve statin adherence should take gender-specific challenges into consideration such as women being older at the time of increased CVD risk, higher rates of statin intolerance, and potentially greater caregiving responsibilities. PMID- 27696321 TI - G4-Tetra DNA Duplex Induce Lung Cancer Cell Apoptosis in A549 Cells. AB - The specific DNA is typically impermeable to the plasma membrane due to its natural characters, but DNA tetra structures (DTNs) can be readily uptake by cells in the absence of transfection agents, providing a new strategy to deliver DNA drugs. In this research, the delivery efficiency of tetrahedral DNA nanostructures was measured on adenocarcinomic human alveolar basal epithelial (A549) cells via delivering AS1411 (G4). The DNA tetra-AS1411 complex was rapidly and abundantly uptake by A549 cells, and the induced apoptosis was enhanced. Furthermore, biodistribution in mouse proved the rapid clearance from non targeted organs in vivo. This study improved the understanding of potential function in DNA-based drug delivery and proved that DTNs-AS1411 could be potentially useful for the treatment of lung cancer. PMID- 27696322 TI - Fabrication of NaYF4:Yb,Er Nanoprobes for Cell Imaging Directly by Using the Method of Hydrion Rivalry Aided by Ultrasonic. AB - A novel method of fabricating water-soluble bio-probes with ultra-small size such as NaYF4:Yb,Er (18 nm), NaGdF4:Yb,Er (8 nm), CaF2:Yb,Er (10 nm), PbS (7 nm), and ZnS (12 nm) has been developed to provide for the solubility switch of nanoparticles from oil-soluble to water-soluble in terms of hydrion rivalry aided by ultrasonic. Using NaYF4:Yb,Er (18 nm) as an example, we evaluate the properties of as-prepared water-soluble nanoparticles (NPs) by using thermogravimetric analyses (TGA), Fourier transform infrared spectroscopy (FTIR), zeta potential (zeta) testing, and 1H nuclear magnetic resonance (1HNMR). The measured zeta value shows that the newly prepared hydrophilic NaYF4:Yb,Er NPs are the positively charged particles. Acting as reactive electrophilic moiety, the freshly prepared hydrophilic NaYF4:Yb,Er NPs have carried out the coupling with amino acids and fluorescence labeling and imaging of HeLa cells directly. Experiments indicate that the method of hydrion rivalry aided by ultrasonic provides a simple and novel opportunity to transform hydrophobic NPs into hydrophilic NPs with good reactivity, which can be imaging some specific biological targets directly. PMID- 27696323 TI - Synthesis of Ultrathin WS2 Nanosheets and Their Tribological Properties as Lubricant Additives. AB - In this paper, ultrathin WS2 nanosheets with thickness of about 5 nm were successfully prepared by a facile solid phase reaction method. The as-synthesized samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). On the basis of experimental results obtained under different reaction durations, a possible formation mechanism of WS2 nanosheets is proposed. The tribological performance of ultrathin WS2 nanosheets as additives in the 500SN base oil was tested by an UMT-2 ball-on-disc tribotester, and the worn surface of the steel disc was investigated by a non-contact optical profile testing instrument and SEM. The results showed that the friction coefficient and anti-wear property of base oil can be improved strikingly by adding ultrathin WS2 nanosheets. Especially, when the concentration of WS2 nanosheets was 1.0 wt.%, the corresponding lubricating oil exhibited the best tribological properties. Moreover, according to the investigation of the wear scar, an anti-friction and anti-wear mechanism is proposed. It is believed that the reduction of friction and wear must come from the addition of ultrathin WS2 nanosheets which can penetrate and enter the friction interface and form a continuous tribofilm on the rubbing face. PMID- 27696324 TI - Neighborhood Deprivation during Early Childhood and Conduct Problems in Middle Childhood: Mediation by Aggressive Response Generation. AB - The tremendous negative impact of conduct problems to the individual and society has provided the impetus for identifying risk factors, particularly in early childhood. Exposure to neighborhood deprivation in early childhood is a robust predictor of conduct problems in middle childhood. Efforts to identify and test mediating mechanisms by which neighborhood deprivation confers increased risk for behavioral problems have predominantly focused on peer relationships and community-level social processes. Less attention has been dedicated to potential cognitive mediators of this relationship, such as aggressive response generation, which refers to the tendency to generate aggressive solutions to ambiguous social stimuli with negative outcomes. In this study, we examined aggressive response generation, a salient component of social information processing, as a mediating process linking neighborhood deprivation to later conduct problems at age 10.5. Participants (N = 731; 50.5 % male) were drawn from a multisite randomized prevention trial that includes an ethnically diverse and low-income sample of male and female children and their primary caregivers followed prospectively from toddlerhood to middle childhood. Results indicated that aggressive response generation partially mediated the relationship between neighborhood deprivation and parent- and teacher-report of conduct problems, but not youth-report. Results suggest that the detrimental effects of neighborhood deprivation on youth adjustment may occur by altering the manner in which children process social information. PMID- 27696325 TI - What is new in idiopathic clubfoot? AB - Idiopathic clubfoot has a tremendous worldwide prevalence. If left untreated, the deformity has severely disabling effects on mobility and quality of life. Given its prevalence and significance, numerous studies are published on this condition every year. In this article, we attempt to highlight important themes and findings of studies published on idiopathic clubfoot over the past 3 years. PMID- 27696326 TI - TLR4 and TLR21 expression, MIF, IFN-beta, MD-2, CD14 activation, and sIgA production in chickens administered with EFAL41 strain challenged with Campylobacter jejuni. AB - The protective effect of Enterococcus faecium EFAL41 on chicken's caecum in relation to the TLR (TLR4 and TLR21) activation and production of luminal IgA challenged with Campylobacter jejuni CCM6191 was assessed. The activation of MIF, IFN-beta, MD-2 and CD14 was followed-up after bacterial infection. Day-old chicks (40) were divided into four groups (n = 10): control (C), E. faecium AL41 (EFAL41), C. jejuni (CJ) and combined E. faecium AL41+C. jejuni (EFAL41+CJ). Relative mRNA expression of TLR4, TLR21 and CD14 was upregulated in the probiotic strain and infected (combined) group on day 4 and 7 post infection (p.i.). The caecal relative MD-2 mRNA expression was upregulated on day 4 p.i. in the EFAL41+CJ and CJ groups. MIF and IFN-beta reached the highest levels in the combined groups on day 7 p.i. The concentration of the sIgA in intestinal flush was upregulated in EFAL41+CJ group on day 4 p.i. The results demonstrated that E. faecium EFAL41 probiotic strain can modulate the TLRs expression and modify the activation of MIF, IFN-beta, MD-2 and CD14 molecules in the chickens caecum challenged with C. jejuni CCM 6191. The counts of EFAL41 were sufficient and high, similarly the counts of enterococci in both, caecum and faeces but without reduction of Campylobacter counts. PMID- 27696328 TI - Determinants of Voluntary National Health Insurance Drop-Out in Eastern Sudan. AB - BACKGROUND: Low enrolment and high drop-out rates are common problems in voluntary health insurance schemes. Yet, most studies in this research area focus on community-based health insurance and enrolment, rather than drop-out. OBJECTIVE: This study examines what causes informal sector families not to renew their voluntary National Health Insurance Fund (NHIF) health insurance membership in Eastern Sudan. METHODS: Primary data from about 600 informal sector households that dropped out or remained insured, collected through a household survey conducted in March 2014, were used. Logistic regressions were employed to examine what determines drop-out of the voluntary NHIF scheme. RESULTS: The logistic regression results are consistent with the existing literature and confirm the importance of household head, household and community characteristics. Notably, worse family health status and higher health care utilization decrease the probability of drop-out, which requires further analysis as it may indicate the problem of adverse selection and insufficient risk management. Most importantly, the results consistently show that household heads who are satisfied with health services and those who understand the main features of the voluntary NHIF scheme are less likely to drop out. Also, 30 % of drop-out households hold a social support card and reported that the social support scheme is the main reason for not renewing their voluntary NHIF health insurance membership as they qualify for sponsored NHIF health insurance membership. CONCLUSIONS: This study shows that satisfaction with health services and knowledge of the health insurance scheme are important factors explaining drop-out of a national health insurance programme. The results suggest that education and information campaigns should be developed further to raise understanding of the NHIF voluntary scheme. In addition, information systems and coordination between the main agencies should be strengthened to reduce administrative costs and ensure policy coherence. PMID- 27696327 TI - Genetic trends for live weight traits reflect breeding strategies in registered Charolais Farms in Mexico. AB - Genetic trends are commonly used to verify genetic improvement; however, there are few reports on beef cattle in Mexico. Data from 1998 to 2013 from four Charolais bull breeding farms were examined to verify the genetic responses to different breeding management and selection criteria. Analysis included the comparison of regression lines of breeding values for birth (BW), weaning (WW) and yearling weights (YW), and maternal weaning weight (MWW) on the year of birth of the animals. Results revealed differential genetic progress for BW and YW and indicated that the overall analysis may have diluted the perception of genetic progress from the farmer's point of view. The use of breeding values as a tool for selection is effective to achieve genetic progress, even in negatively correlated traits, such as birth weight and yearling weight. PMID- 27696329 TI - Sustained Depolarization of the Resting Membrane Potential Regulates Muscle Progenitor Cell Growth and Maintains Stem Cell Properties In Vitro. AB - It is important to maintain the myogenic properties of muscle progenitor cells (MPCs) during in vitro expansion for stem cell therapies and tissue engineering applications. Controlling cell fate for biomedical interventions will require insight on all aspects that influence cellular properties. The resting membrane potential (Vmem) has proven to be a key parameter involved in cell proliferation, migration and differentiation. This current work is focused on elucidating the impact of sustained depolarization on MPC growth and differentiation in vitro. Cultures were treated with either potassium gluconate or the sodium-potassium pump blocker ouabain and evaluated for proliferation, DNA content using propidum iodide staining, and differentiation. Cell proliferation measurements showed a modest stimulatory effect at certain concentration ranges for each agent, but higher concentrations of potassium gluconate strongly inhibited growth in a dose dependent manner. Cell cycle analysis with flow cytometry demonstrated an increase in the number of cells in S phase, but increasing concentrations of potassium gluconate arrested cells at G1. Immunostaining, Western blot analysis and light microscopy revealed that potassium gluconate exposure delayed cell fusion and maintained a higher population of cells expressing the muscle stem cell marker Pax7. The impairment on cell fusion was transient and myotube formation recovered after the treatments were removed. Taken together, this work suggests that transmembrane voltage gradients can be used as a powerful regulator of MPC properties in vitro. Examination of how these physiological parameters modulate cell behavior will reveal a new set of tools that can be capitalized on in tissue engineering and regenerative medicine. PMID- 27696330 TI - DNA sensor cGAS-mediated immune recognition. AB - The host takes use of pattern recognition receptors (PRRs) to defend against pathogen invasion or cellular damage. Among microorganism-associated molecular patterns detected by host PRRs, nucleic acids derived from bacteria or viruses are tightly supervised, providing a fundamental mechanism of host defense. Pathogenic DNAs are supposed to be detected by DNA sensors that induce the activation of NFkappaB or TBK1-IRF3 pathway. DNA sensor cGAS is widely expressed in innate immune cells and is a key sensor of invading DNAs in several cell types. cGAS binds to DNA, followed by a conformational change that allows the synthesis of cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) from adenosine triphosphate and guanosine triphosphate. cGAMP is a strong activator of STING that can activate IRF3 and subsequent type I interferon production. Here we describe recent progresses in DNA sensors especially cGAS in the innate immune responses against pathogenic DNAs.

AB - Human telomerase reverse transcriptase (hTERT) plays a central role in telomere lengthening for continuous cell proliferation, but it remains unclear how extracellular cues regulate telomerase lengthening of telomeres. Here we report that the cytokine bone morphogenetic protein-7 (BMP7) induces the hTERT gene repression in a BMPRII receptor- and Smad3-dependent manner in human breast cancer cells. Chonic exposure of human breast cancer cells to BMP7 results in short telomeres, cell senescence and apoptosis. Mutation of the BMPRII receptor, but not TGFbRII, ACTRIIA or ACTRIIB receptor, inhibits BMP7-induced repression of the hTERT gene promoter activity, leading to increased telomerase activity, lengthened telomeres and continued cell proliferation. Expression of hTERT prevents BMP7-induced breast cancer cell senescence and apoptosis. Thus, our data suggest that BMP7 induces breast cancer cell aging by a mechanism involving BMPRII receptor- and Smad3-mediated repression of the hTERT gene.

AB - The function of right ventricle (RV) is recognized to play a key role in the development of many cardiopulmonary disorders, such as pulmonary arterial hypertension (PAH). Given the strong link between tissue structure and mechanical behavior, there remains a need for a myocardial constitutive model that accurately accounts for right ventricular myocardium architecture. Moreover, most available myocardial constitutive models approach myocardium at the length scale of mean fiber orientation and do not explicitly account for different fibrous constituents and possible interactions among them. In the present work, we developed a fiber-level constitutive model for the passive mechanical behavior of the right ventricular free wall (RVFW). The model explicitly separates the mechanical contributions of myofiber and collagen fiber ensembles, and accounts for the mechanical interactions between them. To obtain model parameters for the healthy passive RVFW, the model was informed by transmural orientation distribution measurements of myo- and collagen fibers and was fit to the mechanical testing data, where both sets of data were obtained from recent experimental studies on non-contractile, but viable, murine RVFW specimens. Results supported the hypothesis that in the low-strain regime, the behavior of the RVFW is governed by myofiber response alone, which does not demonstrate any coupling between different myofiber ensembles. At higher strains, the collagen fibers and their interactions with myofibers begin to gradually contribute and dominate the behavior as recruitment proceeds. Due to the use of viable myocardial tissue, the contribution of myofibers was significant at all strains with the predicted tensile modulus of [Formula: see text]32 kPa. This was in contrast to earlier reports (Horowitz et al. 1988) where the contribution of myofibers was found to be insignificant. Also, we found that the interaction between myo- and collagen fibers was greatest under equibiaxial strain, with its contribution to the total stress not exceeding 20 %. The present model can be applied to organ-level computational models of right ventricular dysfunction for efficient diagnosis and evaluation of pulmonary hypertension disorder.

AB - Triggering receptors expressed on myeloid cell-1 (TREM-1) is a superimmunoglobulin receptor expressed on myeloid cells. TREM-1 amplifies the inflammatory response. Epoxyeicosatrienoic acids (EETs), the metabolites of arachidonic acid derived from the cytochrome P450 enzyme, have anti-inflammatory properties. However, the effects of EETs on TREM-1 expression under inflammatory stimulation remain unclear. Therefore, inhibition of soluble epoxide hydrolase (sEH) with a highly selective inhibitor [1-trifluoromethoxyphenyl-3-(1 propionylpiperidin-4-yl) urea, TPPU] was used to stabilize EETs. LPS was intratracheally injected into mice to induce pulmonary inflammation, after TPPU treatment for 3 h. Histological examination showed TPPU treatment-alleviated LPS induced pulmonary inflammation. TPPU decreased TREM-1 expression, but not DAP12 or MyD88 expression. Murine peritoneal macrophages were challenged with LPS in vitro. We found that TPPU reduced LPS-induced TREM-1 expression in a dose dependent manner, but not DAP12 or MyD88 expression. TPPU also decreased downstream signal from TREM-1, reducing pro-inflammatory cytokine TNF-alpha and IL-1beta mRNA expression. Furthermore, TPPU treatment inhibited IkB degradation in vivo and in vitro. Our results indicate that the inhibition of sEH suppresses LPS-induced TREM-1 expression and inflammation via inhibiting NF-kB activation in murine macrophage.

AB - Plasma levels of Rivaroxaban (RivLev) might be useful to guide therapeutic decisions in patients with acute stroke under Rivaroxaban. A prerequisite for the potential clinical usefulness is their rapid availability in emergency situations. Single-center explorative analysis from the Novel-Oral-Anticoagulants in-Stroke-Patients-registry (NOACISP, cinicaltrials.gov:NCT02353585). We included consecutive patients with acute ischemic or hemorrhagic stroke under Rivaroxaban (last intake <48 h) in which RivLev determined by an automated anti-factor Xa based chromogenic assay (Hyphen-Biomed, France) are available. Primary endpoint was the turnaround time (TAT), defined as time from registration of the blood sample in the lab to first result published. Furthermore, we studied, whether TAT is influenced by (1) on- and off-hour-measurements and (2) early versus later patient arrival (cut-off: 270 min after symptom onset). Thirty-eight patients met the eligibility criteria (mean age 77 years, 44 % female). TAT was 34 min (IQR 29 65 min). TATs were similar for on- (n = 14; median 34 min; IQR 30-56 min) and off hours-TATs (n = 24; median 35 min; IQR 29-75 min) as well as for early (n = 16; median 33 min; IQR 30-40 min) and late patient arrival (n = 22, median 34 min, IQR 28-58 min; all nonsignificant.). Taking into account RivLev in the decision process about the use of intravenous thrombolysis, three patients received intravenous thrombolysis on an individualized basis, none of them with bleeding complications. Emergency measurement of RivLev among patients with acute stroke is available within a median of 34 min and therefore feasible for ED use. Due to the rapid availability, further research to evaluate the role of RivLev in order to guide acute treatment decisions is warranted. PMID- 27696336 TI - Study on the Composition of Biogenic Iron-Containing Materials Obtained Under Cultivation of the Leptothrix sp. on Different Media. AB - The biogenic iron oxide/hydroxide materials possess useful combination of physicochemical properties and are considered for application in various areas. Their production does not require special investments because these compounds are formed during cultivation of neurophilic iron bacteria. Bacteria from genus Leptothrix develop intensively in the Sphaerotilus-Leptothrix group of bacteria isolation medium and feeding media of Fedorov and Lieske. These media are different in their composition which determined the present study as an attempt to clear up the reasons that define the differences in the composition of the laboratory-obtained biomasses and the natural biomass finds. FTIRS, Mossbauer spectroscopy, and XRD were used in the research. Comparative analysis showed that the biomass and control samples contain iron compounds (alpha-FeOOH, gamma-FeOOH, beta-FeOOH, gamma-Fe2O3) in different ratios. The biomass samples were enriched in oxyhydroxides of higher dispersion. Organic residuals of bacterial origin, SO4, CO3, and PO4 groups were registered in the biogenic materials. PMID- 27696337 TI - The Psycho-Neurology of Cross-Species Affective/Social Neuroscience: Understanding Animal Affective States as a Guide to Development of Novel Psychiatric Treatments. AB - During the past half century of research with preclinical animal models, affective neuroscience has helped identify and illuminate the functional neuroanatomies and neurochemistries of seven primary process, i.e., genetically provided emotional systems of mammalian brains. All are subcortically localized, allowing animal models to guide the needed behavioral and neuroscientific analyses at levels of detail that cannot be achieved through human research, including modern brain imaging. They consist of the following neuronal processes: SEEKING/Enthusiasm, RAGE/Anger, FEAR/Anxiety, sexual LUST/Passion, maternal CARE/Nurturance, separation-distress PANIC/Grief and PLAY/Social Joy. Several of these systems figure heavily in social bonding. I will focus here especially on the genesis of depression. Its genesis is significantly influenced by (i) sustained overactivity of the separation-distress PANIC system reflecting severed social bonds and the excessive "psychological pain" of loneliness that can, if sustained, lead to a downward cascade known as psychological despair, and (ii) the despair phase that follows the acute PANIC response, which is characterized by abnormally low activity of the SEEKING, the so-called brain reward networks, leading to amotivational states that characterize depression. Depressive affect is promoted by such brain affective mechanisms of social attachments and social loss as well as diminished arousability of the SEEKING system, leading to chronic dysphoria. To understand why depression feels so bad, we must understand the neural mechanisms that mediate such social feelings. PMID- 27696334 TI - Interleukin-35: a Potential Therapeutic Agent for Autoimmune Diseases. AB - Autoimmune diseases contain a large number of pathologies characterized by various factors that contribute to a breakdown in self-tolerance. Cytokine mediated immunity plays an essential role in the pathogenesis of varieties of autoimmune diseases. Recent studies reveal that interleukin-35 (IL-35), a newly identified cytokine of IL-12 family, is implicated in the pathogenesis of autoimmune diseases, such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), systemic sclerosis (SSc), etc. In this review, we will discuss the biological features of IL-35 and summarize recent advances in the role of IL 35 in the development and pathogenesis of autoimmune diseases; the discoveries gained from these findings might translate into future therapies for these diseases. PMID- 27696338 TI - Influence of IGF1, TGFbeta1, bFGF and G-CSF/M-CSF on the mRNA levels of selected matrix proteins, cytokines, metalloproteinase 3 and TIMP1 in rat synovial membrane cells. AB - INTRODUCTION: We have previously observed that rat synovial membranes incubated in medium containing cartilage interstitial fluid (CIF) responded by changes in the expression of hyaluronan synthases (HAS1 and HAS2), collagen type I, versican, aggrecan, lubricin, matrix metalloproteinases 2 and 3 (MMP2 and MMP3), tissue inhibitors of metalloproteinases (TIMP1, 2 and 3), transforming growth factor beta1 (TGFbeta1), tumor necrosis factor (TNF), interleukin (IL) 1beta and IL-6. The aim of the study was to evaluate the influence of particular cytokines found in CIF on the gene expression of extracellular matrix (ECM) proteins in synovial membrane cells. MATERIAL AND METHODS: Synovial membranes (SMs) were removed from the knee joints of inbred, male Lewis rats and incubated with insulin-like growth factor 1 (IGF1), TGFbeta1, basic fibroblast growth factor (bFGF) and granulocyte- macrophage colony-stimulating factors (G-CSF and M-CSF), either individually or in the combinations TGFbeta1/IGF1, TGFbeta1/IGF1/bFGF or G CSF/M-CSF. Next, total RNA was isolated and the studied genes' expression was evaluated by real-time PCR. RESULTS: TGFbeta1/IGF1 stimulated expression of HAS1, lubricin, collagen type I, aggrecan and TGFbeta1, inhibited expression of MMP3 and TNF and had no effect on TIMP1 and IL-6 mRNA levels. TGFbeta1/IGF1/bFGF stimulated the expression of HAS1, lubricin and TGFbeta1 genes, inhibited the expression of TNF and had no effect of the expression of collagen 1, aggrecan, MMP3, TIMP1 and IL-6 genes. G-CSF/M-CSF stimulated the expression of aggrecan. TGFbeta1, bFGF, and IGF1 applied individually exerted inhibitory effect on the expression of lubricin. TGFbeta1 and bFGF inhibited expression of MMP3 and bFGF inhibited also the expression of aggrecan and TNF. CONCLUSIONS: The response of the studied genes represents a resultant activity of all major cell types building the synovial membrane, i.e. highly specialized synovial fibroblasts, macrophages, epithelial cells and adipocytes. The results of our study can improve understanding of synovial membrane responses to the intraarticular injections of platelet-rich plasma (PRP) used for the treatment of joint ailments, since PRP contains factors which are also present in CIF. PMID- 27696339 TI - Effects of sugammadex vs. pyridostigmine-glycopyrrolate on post-operative nausea and vomiting: propensity score matching. AB - BACKGROUND: Sugammadex is a new agent that reverses neuromuscular blockade by aminosteroid neuromuscular blocker. This retrospective study compared the effects of sugammadex on post-operative nausea and vomiting (PONV) with those of a pyridostigmine-glycopyrrolate mixture. METHODS: We reviewed the electronic medical records of 7179 patients who had received fentanyl-based, intravenous, patient-controlled analgesia (IV-PCA) at Chung-Ang University Hospital between January 1, 2010 and December 31, 2015. We categorized the patients into two groups on the basis of the type of reversal agent to neuromuscular blockade that was used: a traditional reversal agent (pyridostigmine-glycopyrrolate mixture; Group R; n = 7059) and sugammadex (Group S; n = 120). The propensity score matching method was then used to select 408 subjects in Group R and 115 subjects in Group S; on the basis of their covariates, these subjects were then matched with a counterpart in the other group. RESULTS: After propensity score matching, the two groups were well balanced with respect to all baseline covariates. In Group S, the numeric rating scale of nausea on day 0, as well as the number of patients who vomited on day 0, was lower than that in group R. Furthermore, Group S used fewer rescue antiemetics on day 0 and had a higher complete response on day 0. CONCLUSION: Sugammadex might be more beneficial for PONV compared to pyridostigmine-glycopyrrolate mixture for patients who have received opioid-based IV-PCA. PMID- 27696340 TI - Maternal and fetal characteristics affect discrepancies between pregnancy-dating methods: a population-based cross-sectional register study. AB - INTRODUCTION: Gestational age is estimated by ultrasound using fetal size as a proxy for age, although variance in early growth affects reliability. The aim of this study was to identify characteristics associated with discrepancies between last menstrual period-based (EDD-LMP) and ultrasound-based (EDD-US) estimated delivery dates. MATERIAL AND METHODS: We identified all singleton births (n = 1 201 679) recorded in the Swedish Medical Birth Register in 1995-2010, to assess the association between maternal/fetal characteristics and large negative and large positive discrepancies (EDD-LMP earlier than EDD-US and 10th percentile in the discrepancy distribution vs. EDD-LMP later than EDD-US and 90th percentile). Analyses were adjusted for age, parity, height, body mass index, smoking, and employment status. RESULTS: Women with a body mass index >40 kg/m2 had the highest odds for large negative discrepancies (-9 to -20 days) [odds ratio (OR) 2.16, 95% CI 2.01-2.33]. Other factors associated with large negative discrepancies were: diabetes, young maternal age, multiparity, body mass index between 30 and 39.9 kg/m2 or <18.5 kg/m2 , a history of gestational diabetes, female fetus, shorter stature (<-1 SD), a history of preeclampsia, smoking or snuff use, and unemployment. Large positive discrepancies (+4 to +20 days) were associated with male fetus (OR 1.80, 95% CI 1.77-1.83), age >=30 years, multiparity, not living with a partner, taller stature (>+1 SD), and unemployment. CONCLUSIONS: Several maternal and fetal characteristics were associated with discrepancies between dating methods. Systematic associations of discrepancies with maternal height, fetal sex, and partly obesity, may reflect an influence on the precision of the ultrasound estimate due to variance in early growth. PMID- 27696341 TI - Veterans Affairs Geriatric Scholars Program: Enhancing Existing Primary Care Clinician Skills in Caring for Older Veterans. AB - The Veterans Affairs Geriatric Scholars Program (GSP) is a continuing professional development program to integrate geriatrics into the clinical practices of primary care providers and select associated health professions that support primary care teams. GSP uses a blended program educational format, and the minimal requirements are to attend an intensive course in geriatrics, participate in an interactive workshop on quality improvement (QI), and initiate a local QI project to demonstrate application of new knowledge to benefit older veterans. Using a retrospective post/pre survey design, the effect of GSP on clinical practices and behaviors and variation of that effect on clinicians working in rural and nonrural settings were evaluated. Significant improvement was found in the frequency of using evidence-based brief standardized assessments, clinical decision-making, and standards of care. Significant subgroup differences were observed in peer-to-peer information sharing between rural and nonrural clinicians. Overall, 77% of the sample reported greater job satisfaction after participating in GSP. The program is a successful model for advancing postgraduate education in geriatrics and a model that might be replicated to increase access to quality health care, particularly in rural areas. PMID- 27696342 TI - Volunteering Is Associated with Lower Risk of Cognitive Impairment. AB - OBJECTIVES: To examine whether psychosocial factors that can be a target for interventions, such as volunteering, are associated with risk of cognitive impairment. DESIGN: Health and Retirement Study (HRS) data from 1998 to 2012, a nationally representative longitudinal panel survey of older adults assessed every 2 years, were used. SETTING: The HRS interviews participants aged 50 and older across the contiguous United States. PARTICIPANTS: Individuals aged 60 and older in 1998 (N = 13,262). MEASUREMENTS: Personal interviews were conducted with respondents to assess presence of cognitive impairment, measured using a composite across cognitive measures. RESULTS: Volunteering at the initial assessment and volunteering regularly over time independently decreased the risk of cognitive impairment over 14 years, and these findings were maintained independent of known risk factors for cognitive impairment. Greater risk of onset of cognitive impairment was associated with being older, being female, being nonwhite, having fewer years of education, and reporting more depressive symptoms. CONCLUSION: Consistent civic engagement in old age is associated with lower risk of cognitive impairment and provides impetus for interventions to protect against the onset of cognitive impairment. Given the increasing number of baby boomers entering old age, the findings support the public health benefits of volunteering and the potential role of geriatricians, who can promote volunteering by incorporating "prescriptions to volunteer" into their patient care. PMID- 27696343 TI - Low degree of satisfactory individual pain relief in post-operative pain trials. AB - BACKGROUND: The majority of clinical trials regarding post-operative pain treatment focuses on the average analgesic efficacy, rather than on efficacy in individual patients. It has been argued, that in acute pain trials, the underlying distributions are often skewed, which makes the average unfit as the only way to measure efficacy. Consequently, dichotomised, individual responder analyses using a predefined 'favourable' response, e.g. Visual Analogue Scale (VAS) pain scores <= 30, have recently been suggested as a more clinical relevant outcome. METHODS: We re-analysed data from 16 randomised controlled trials of post-operative pain treatment and from meta-analyses of a systematic review regarding hip arthroplasty. The predefined success criterion was that at least 80% of patients in active treatment groups should obtain VAS < 30 at 6 and 24 h post-operatively. RESULTS: In the analysis of data from the randomised controlled trials, we found that at 6 h post-operatively, 50% (95% CI: 31-69) of patients allocated to active treatment reached the success criterion for pain at rest and 14% (95% CI: 5-34) for pain during mobilisation. At 24 h post-operatively, 60% (95% CI: 38-78) of patients allocated to active treatment reached the success criterion for pain at rest, and 15% (95% CI: 5-36) for pain during mobilisation. Similar results were found for trials from the meta-analyses. CONCLUSION: Our results indicate that for conventional, explanatory trials of post-operative pain, individual patient's achievement of a favourable response to analgesic treatment is rather low. Future pragmatic clinical trials should focus on both average pain levels and individual responder analyses in order to promote effective pain treatment at the individually patient level. PMID- 27696344 TI - Velamentous or marginal cord insertion and the risk of spontaneous preterm birth, prelabor rupture of the membranes, and anomalous cord length, a population-based study. AB - INTRODUCTION: Anomalous cord insertion is associated with increased risk of adverse maternal and perinatal outcome. Our aim was to study whether anomalous cord insertion is associated with prelabor rupture of membranes (PROM), preterm PROM (pPROM), long or short umbilical cord, and time trend of spontaneous preterm birth (SPTB) and anomalous cord insertion. MATERIAL AND METHODS: A population based register study using data from the Medical Birth Register of Norway including all singleton births (gestational age >16 weeks and <45 weeks) during 1999-2013 (n = 860 465) to calculate odds ratios (ORs) for PROM, pPROM, SPTB, and cord length (>95th or <5th centile) according to the cord insertion site by logistic regression with adjustment for possible confounders. We also assessed time trends of SPTB and anomalous cord insertion. RESULTS: Velamentous insertion of the cord was associated with an increased risk of PROM (OR 1.6, 95% CI 1.5 1.7), pPROM (OR 2.7, 95% CI 2.4-3.0), SPTB (OR 2.0, 95% CI 1.9-2.2), and a short cord (OR 1.7, 95% CI 1.5-1.8). Marginal insertion was to a lesser extent associated with these complications. Occurrences of SPTB and anomalous insertion declined. The decline in SPTB persisted after including an interaction term between anomalous insertion and time. CONCLUSIONS: Velamentous and, to a lesser extent, marginal cord insertions were associated with increased risk of PROM, pPROM, SPTB, and short cord. This suggests a common pathogenesis behind altered function of the membranes, cord, and placenta. The decline in SPTB could not be explained by the reduction in the occurrence of anomalous cord insertion. PMID- 27696345 TI - The productive cellulase binding capacity of cellulosic substrates. AB - Cellulosic biomass is the most promising feedstock for renewable biofuel production; however, the mechanisms of the heterogeneous cellulose saccharification reaction are still unsolved. As cellulases need to bind isolated molecules of cellulose at the surface of insoluble cellulose fibrils or larger aggregated cellulose structures in order to hydrolyze glycosidic bonds, the "accessibility of cellulose to cellulases" is considered to be a reaction limiting property of cellulose. We have defined the accessibility of cellulose to cellulases as the productive binding capacity of cellulose, that is, the concentration of productive binding sites on cellulose that are accessible for binding and hydrolysis by cellulases. Productive cellulase binding to cellulose results in hydrolysis and can be quantified by measuring hydrolysis rates. In this study, we measured the productive Trichoderma reesei Cel7A (TrCel7A) binding capacity of five cellulosic substrates from different sources and processing histories. Swollen filter paper and bacterial cellulose had higher productive binding capacities of ~6 umol/g while filter paper, microcrystalline cellulose, and algal cellulose had lower productive binding capacities of ~3 umol/g. Swelling and regenerating filter paper using phosphoric acid increased the initial accessibility of the reducing ends to TrCel7A from 4 to 6 umol/g. Moreover, this increase in initial productive binding capacity accounted in large part for the difference in the overall digestibility between filter paper and swollen filter paper. We further demonstrated that an understanding of how the productive binding capacity declines over the course of the hydrolysis reaction has the potential to predict overall saccharification time courses.

AB - INTRODUCTION: To evaluate the effectiveness of the levonorgestrel intrauterine system (LNG-IUS) in obese women with heavy menstrual bleeding in Counties Manukau Auckland area, New Zealand. METHODS: Prospective observational study in a tertiary teaching hospital. Twenty women with heavy menstrual bleeding (HMB) who agreed to treatment with the LNG-IUS and had a body mass index (BMI) of >30 kg/m2 were recruited between May and December 2014. The women completed two validated tools (Menstrual Impact Questionnaire and the Pictorial Bleeding Assessment Chart) at recruitment, 6 and 12 months follow-up. Demographic, medical and laboratory variables were obtained from the relevant CMH databases. Data on side effects and satisfaction were obtained from the women at 12 months. RESULTS: The median age (range) and BMI of the 20 women were 40.5 years (27-52 years) and 40.6 kg/m2 (30-68), respectively. Three LNG-IUS were removed due to infection and pain and these women were subsequently booked for a hysterectomy. The reduction in menstrual loss was estimated at 19.7% per month (95% CI (12.5%, 26.2%); P < 0.001), which translates to 73.2% per period of 6 months (95% CI (55.3%, 83.9%)) and 92.8% per period of 12 months (95% CI (80.0%, 97.4%)). The six items in the quality of life measure improved significantly in 14 women but only 12 women were satisfied with the treatment. CONCLUSION: The LNG-IUS was an effective treatment for 67% of obese women with heavy menstrual bleeding over a 12-month period, as assessed by the reduction in menstrual bleeding and the improvement in the quality of life measures. PMID- 27696347 TI - Lateral enamel growth in human incisors from Catalhoyuk in Turkey. AB - OBJECTIVES: Whereas the differences in lateral enamel growth between fossil and modern populations have been well documented in recent years, few studies report on the variability in perikymata counts and distribution between modern human populations. There is a need for information on modern human populations from a wide range of geographical regions and archaeological populations to determine whether existing patterns are representative. The aim of this paper is to document enamel surface microstructures in human teeth from a previously unknown region and time period comprehensively. MATERIALS AND METHODS: Perikymata counts and distribution are assessed in a large sample of relatively unworn permanent incisors from the mid-Holocene site of Catalhoyuk in Turkey. RESULTS: All four incisor types exhibit total perikymata counts that are intermediate between values for modern samples from northern Europe and South Africa. The perikymata distribution followed the modern human pattern of a marked decrease in spacing in the cervical half of the crown. DISCUSSION: The existence of regional differences in perikymata number and distribution demonstrates the importance of documenting enamel microstructures in a wider range of modern human populations, both geographically and chronologically.

AB - In the present work, different biopolymer blend scaffolds based on the silk protein fibroin from Bombyx mori (BM) were prepared via freeze-drying method. The chemical, structural, and mechanical properties of the three dimensional (3D) porous silk fibroin (SF) composite scaffolds of gelatin, collagen, and chitosan as well as SF from Antheraea pernyi (AP) and the recombinant spider silk protein spidroin (SSP1) have been systematically investigated, followed by cell culture experiments with epithelial prostate cancer cells (LNCaP) up to 14 days. Compared to the pure SF scaffold of BM, the blend scaffolds differ in porous morphology, elasticity, swelling behavior, and biochemical composition. The new composite scaffold with SSP1 showed an increased swelling degree and soft tissue like elastic properties. Whereas, in vitro cultivation of LNCaP cells demonstrated an increased growth behavior and spheroid formation within chitosan blended scaffolds based on its remarkable porosity, which supports nutrient supply matrix. Results of this study suggest that silk fibroin matrices are sufficient and certain SF composite scaffolds even improve 3D cell cultivation for prostate cancer research compared to matrices based on pure biomaterials or synthetic polymers.

PMID- 27696350 TI - Effect of Geriatric-Specific Trauma Triage Criteria on Outcomes in Injured Older Adults: A Statewide Retrospective Cohort Study. AB - OBJECTIVES: To evaluate the effect on outcomes of the Ohio Department of Public Safety statewide geriatric triage criteria, established in 2009 for emergency medical services (EMS) to use for injured individuals aged 70 and older. DESIGN: Retrospective cohort study of the Ohio Trauma Registry. SETTING: All hospitals in Ohio. PARTICIPANTS: Individuals aged 70 and older in the Ohio Trauma Registry from January 2006 through December 2011, 3 years before and 3 years after criteria adoption (N = 34,499). MEASUREMENTS: Primary outcomes were in-hospital mortality and discharge to home. Criteria effects were assessed using chi-square tests, multivariable logistic regression, interrupted time series plots, and multivariable segmented regression models. RESULTS: After geriatric criteria were adopted, the proportion of older adults qualifying for trauma center transport increased from 44% to 58%, but EMS transport rates did not change (44% vs 45%). There was no difference in unadjusted mortality (7.1% vs 6.6%) (P = .10). In adjusted analyses, subjects with an injury severity score (ISS) less than 10 had lower mortality after adoption (3.0% vs 2.5%) (odds ratio (OR) = 0.81, 95% confidence interval (CI) = 0.70-0.95, P = .01). Discharge to home increased after adoption in the adjusted analysis (OR = 1.06, 95% CI = 1.01-1.11, P = .02). There were no time-dependent changes for either outcome. CONCLUSION: Although the proportion of older adults meeting criteria for trauma center transport substantially increased with geriatric triage criteria, there were no increases in trauma center transports. Adoption of statewide geriatric triage guidelines did not decrease mortality in more severely injured older adults but was associated with slightly lower mortality in individuals with mild injuries (ISS <10) and with more individuals discharged to home. Improving outcomes in injured older adults will require further attention to implementation and use of geriatric-specific criteria. PMID- 27696351 TI - Poundbury Camp in Context-a new Perspective on the Lives of Children from urban and rural Roman England. AB - OBJECTIVES: The current understanding of child morbidity in Roman England is dominated by studies of single sites/regions. Much of the data are derived from third to fifth century AD Poundbury Camp, Dorchester, Dorset, considered an unusual site due to high levels of non-adult morbidity. There is little understanding of children in rural areas, and whether Poundbury Camp was representative of Romano-British childhood. MATERIALS AND METHODS: The study provides the first large scale analysis of child health in urban and rural Roman England, adding to the previously published intra-site analysis of non-adult paleopathology at Poundbury Camp. Age-at-death and pathology prevalence rates were reassessed for 953 non-adults (0-17 years) from five major urban, six minor urban, and four rural sites (first to fifth century AD). The data were compared to the results from 364 non-adults from Poundbury Camp. RESULTS: Rural sites demonstrated higher levels of infant burials, and greater prevalence of cribra orbitalia in the 1.1-2.5 year (TPR 64.3%), and 6.6-10.5 year cohorts (TPR 66.7%). Endocranial lesions were more frequent in the minor urban sample (TPR 15.9%). Three new cases of tuberculosis were identified in urban contexts. Vitamin D deficiency was most prevalent at Poundbury Camp (CPR 18.8%), vitamin C deficiency was identified more frequently in rural settlements (CPR 5.9%). DISCUSSION: The Poundbury Camp data on morbidity and mortality are not representative of patterns in Roman England and other major urban sites. Rural children suffered from a distinct set of pathologies described as diseases of deprivation, prompting reconsideration of how Romano-British land management affected those at the bottom of the social hierarchy.

AB - Low molecular weight agents that undergo self-assembly into fibril networks with hydrogel properties are promising biomaterials. Most low molecular weight hydrogelators are discovered empirically or serendipitously due to imperfect understanding of the mechanisms of self-assembly, the packing structure of self assembled materials, and how the self-assembly process corresponds to emergent hydrogelation. Herein, the mechanisms of self-assembly and hydrogelation of N fluorenylmethoxycarbonyl diphenylalanine (Fmoc-PhePhe), a well-studied low molecular weight hydrogelator, is probed by systematic comparison with derivatives in which Phe residues are replaced by corresponding N-benzyl glycine peptoid (Nphe) analogs. Peptoids are peptidomimetics that shift display of side chain functionality from the alpha-carbon to the terminal nitrogen. This alters the hydrogen bonding capacity, the side chain presentation geometry, amide cis/trans isomerization equilibrium, and beta-sheet potential of the peptoid relative to the corresponding amino acid in the context of peptidic polymers. It was found that amino acid/peptoid hybrids Fmoc-Phe-Nphe and Fmoc-Nphe-Phe have altered fibril self-assembly propensity and reduced hydrogelation capacity relative to the parent dipeptide, and that fibril self-assembly of the dipeptoid, Fmoc-Nphe-Nphe, is completely curtailed. These findings provide insight into the potential of low molecular weight peptoids and peptide/peptoid hybrids as hydrogelation agents and illuminate the importance of hydrogen bonding and pi-pi interaction geometry in facilitating self-assembly of Fmoc-Phe-Phe.

AB - We present an integrated framework for the online optimal experimental re-design applied to parallel nonlinear dynamic processes that aims to precisely estimate the parameter set of macro kinetic growth models with minimal experimental effort. This provides a systematic solution for rapid validation of a specific model to new strains, mutants, or products. In biosciences, this is especially important as model identification is a long and laborious process which is continuing to limit the use of mathematical modeling in this field. The strength of this approach is demonstrated by fitting a macro-kinetic differential equation model for Escherichia coli fed-batch processes after 6 h of cultivation. The system includes two fully-automated liquid handling robots; one containing eight mini-bioreactors and another used for automated at-line analyses, which allows for the immediate use of the available data in the modeling environment. As a result, the experiment can be continually re-designed while the cultivations are running using the information generated by periodical parameter estimations. The advantages of an online re-computation of the optimal experiment are proven by a 50-fold lower average coefficient of variation on the parameter estimates compared to the sequential method (4.83% instead of 235.86%). The success obtained in such a complex system is a further step towards a more efficient computer aided bioprocess development. Biotechnol. Bioeng. 2017;114: 610-619. (c) 2016 Wiley Periodicals, Inc.

AB - OBJECTIVES: To evaluate the relationship between life-space mobility (extent, frequency, independence of movement) and mortality in older women. DESIGN: Prospective cohort study. SETTING: Four U.S. clinical sites. PARTICIPANTS: Women (N = 1,498) aged 75 to 102 (mean 87.6) followed from 2006 to 2015. MEASUREMENTS: Life-space during the past 4 weeks was assessed in an interview, scored from 0 (daily restriction to bedroom) to 120 (daily trips outside town without assistance), and categorized (0-20, 21-40, 41-60, 61-80, 81-120). All-cause mortality was the primary outcome; noncancer, cardiovascular, cancer, and noncardiovascular noncancer mortality were secondary outcomes. RESULTS: Over a mean 5.2 years, 842 (56.2%) women died. Unadjusted risk of all-cause mortality was 82.6% in women with the lowest level of life-space (0-20 points) and 36.2% in those with the highest level (81-120 points). In multivariable proportional hazards models, there was a strong relationship between less life-space and greater risk of all-cause mortality (Ptrend < .001). Women with the lowest level of life-space (0-20 points) had a risk of all-cause mortality that was 2.4 times as high (95% confidence interval (CI) = 1.5-4.0) as that of women with the highest level (81-120 points); women with life-space scores between 21 and 60 had a risk of all-cause mortality that was 1.5 times as high as that of women with the highest level. Each standard deviation decrease in life-space was associated with a 1.2 times greater (95% CI = 1.1-1.4) risk of all-cause mortality. Women unable to travel beyond their neighborhood without assistance had a risk of all cause mortality that was 1.4 times (95% CI = 1.1-1.7) as high as that of women who could travel beyond their neighborhood without assistance. Results were similar for noncancer, cardiovascular, and other mortality and did not change after controlling for underlying disease or living arrangement. CONCLUSION: Life space scores of 60 or less were associated with mortality in older women independent of other strong risk factors. PMID- 27696355 TI - Surgery for women with apical vaginal prolapse. AB - BACKGROUND: Apical vaginal prolapse is a descent of the uterus or vaginal vault (post-hysterectomy). Various surgical treatments are available and there are no guidelines to recommend which is the best. OBJECTIVES: To evaluate the safety and efficacy of any surgical intervention compared to another intervention for the management of apical vaginal prolapse. SEARCH METHODS: We searched the Cochrane Incontinence Group's Specialised Register of controlled trials, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched July 2015) and ClinicalTrials.gov (searched January 2016). SELECTION CRITERIA: We included randomised controlled trials (RCTs). DATA COLLECTION AND ANALYSIS: We used Cochrane methods. Our primary outcomes were awareness of prolapse, repeat surgery and recurrent prolapse (any site). MAIN RESULTS: We included 30 RCTs (3414 women) comparing surgical procedures for apical vaginal prolapse. Evidence quality ranged from low to moderate. Limitations included imprecision, poor methodological reporting and inconsistency. Vaginal procedures versus sacral colpopexy (six RCTs, n = 583; one to four-year review). Awareness of prolapse was more common after vaginal procedures (risk ratio (RR) 2.11, 95% confidence interval (CI) 1.06 to 4.21, 3 RCTs, n = 277, I2 = 0%, moderate-quality evidence). If 7% of women are aware of prolapse after sacral colpopexy, 14% (7% to 27%) are likely to be aware after vaginal procedures. Repeat surgery for prolapse was more common after vaginal procedures (RR 2.28, 95% CI 1.20 to 4.32; 4 RCTs, n = 383, I2 = 0%, moderate quality evidence). The confidence interval suggests that if 4% of women require repeat prolapse surgery after sacral colpopexy, between 5% and 18% would require it after vaginal procedures.We found no conclusive evidence that vaginal procedures increaserepeat surgery for stress urinary incontinence (SUI) (RR 1.87, 95% CI 0.72 to 4.86; 4 RCTs, n = 395; I2 = 0%, moderate-quality evidence). If 3% of women require repeat surgery for SUI after sacral colpopexy, between 2% and 16% are likely to do so after vaginal procedures. Recurrent prolapse is probably more common after vaginal procedures (RR 1.89, 95% CI 1.33 to 2.70; 4 RCTs, n = 390; I2 = 41%, moderate-quality evidence). If 23% of women have recurrent prolapse after sacral colpopexy, about 41% (31% to 63%) are likely to do so after vaginal procedures.The effect of vaginal procedures on bladder injury was uncertain (RR 0.57, 95% CI 0.14 to 2.36; 5 RCTs, n = 511; I2 = 0%, moderate quality evidence). SUI was more common after vaginal procedures (RR 1.86, 95% CI 1.17 to 2.94; 3 RCTs, n = 263; I2 = 0%, moderate-quality evidence). Dyspareunia was also more common after vaginal procedures (RR 2.53, 95% CI 1.17 to 5.50; 3 RCTs, n = 106, I2 = 43%, low-quality evidence). Vaginal surgery with mesh versus without mesh (6 RCTs, n = 598, 1-3 year review). Awareness of prolapse - There may be little or no difference between the groups for this outcome (RR 1.08 95% CI 0.35 to 3.30 1 RCT n = 54, low quality evidence). The confidence interval was wide suggesting that if 18% of women are aware of prolapse after surgery without mesh, between 6% and 59% will be aware of prolapse after surgery with mesh. Repeat surgery for prolapse - There may be little or no difference between the groups for this outcome (RR 0.69, 95% CI 0.30 to 1.60; 5 RCTs, n = 497; I2 = 9%, low-quality evidence). If 4% of women require repeat surgery for prolapse after surgery without mesh, 1% to 7% are likely to do so after surgery with mesh.We found no conclusive evidence that surgery with mesh increases repeat surgery for SUI (RR 4.91, 95% CI 0.86 to 27.94; 2 RCTs, n = 220; I2 = 0%, low-quality evidence). The confidence interval was wide suggesting that if 2% of women require repeat surgery for SUI after vaginal colpopexy without mesh, 2% to 53% are likely to do so after surgery with mesh.We found no clear evidence that surgery with mesh decreases recurrent prolapse (RR 0.36, 95% CI 0.09 to 1.40; 3 RCTs n = 269; I2 = 91%, low-quality evidence). The confidence interval was very wide and there was serious inconsistency between the studies. Other outcomes There is probably little or no difference between the groups in rates of SUI (de novo) (RR 1.37, 95% CI 0.94 to 1.99; 4 RCTs, n = 295; I2 = 0%, moderate-quality evidence) or dyspareunia (RR 1.21, 95% CI 0.55 to 2.66; 5 RCTs, n = 501; I2 = 0% moderate-quality evidence). We are uncertain whether there is any difference for bladder injury (RR 3.00, 95% CI 0.91 to 9.89; 4 RCTs, n = 445; I2 = 0%; very low quality evidence). Vaginal hysterectomy versus alternatives for uterine prolapse (six studies, n = 667)No clear conclusions could be reached from the available evidence, though one RCT found that awareness of prolapse was less likely after hysterectomy than after abdominal sacrohysteropexy (RR 0.38, 955 CI 0.15 to 0.98, n = 84, moderate-quality evidence).Other comparisonsThere was no evidence of a difference for any of our primary review outcomes between different types of vaginal native tissue repair (two RCTs), comparisons of graft materials for vaginal support (two RCTs), different routes for sacral colpopexy (four RCTs), or between sacral colpopexy with and without continence surgery (four RCTs). AUTHORS' CONCLUSIONS: Sacral colpopexy is associated with lower risk of awareness of prolapse, recurrent prolapse on examination, repeat surgery for prolapse, postoperative SUI and dyspareunia than a variety of vaginal interventions.The limited evidence does not support use of transvaginal mesh compared to native tissue repair for apical vaginal prolapse. Most of the evaluated transvaginal meshes are no longer available and new lighter meshes currently lack evidence of safetyThe evidence was inconclusive when comparing access routes for sacral colpopexy.No clear conclusion can be reached from the available data comparing uterine preserving surgery versus vaginal hysterectomy for uterine prolapse.

AB - Cel7A from Rasamsonia emersonii is one of the processive endocellulases classified under family 7 glycoside hydrolase. Molecular dynamics simulations were carried out to obtain the optimized sliding and hydrolyzing conformations, in which the reducing ends of sugar chains are located on different sites. Hydrogen bonds are investigated to clarify the interactions between protein and substrate in either conformation. Nine hydrogen bonding interactions are identified in the sliding conformation, and six similar interactions are also found correspondingly in the hydrolyzing conformation. In addition, four strong hydrophobic interactions are also determined. The domain cross-correlation map analysis shows movement correlation of protein including autocorrelation between residues. The root mean square fluctuations analysis represents the various flexibilities of different fragment in the two conformations. Comparing the two conformations reveals the water-supply mechanism of selective hydrolysis of cellulose in Cel7A. The mechanism can be described as follow. When the reducing end of substrate slides from the unhydrolyzing site (sliding conformation) to the hydrolyzing site (hydrolyzing conformation), His225 is pushed down and rotated, the rotation leads to the movement of Glu209 with the interstrand hydrogen bonding in beta-sheet. It further makes Asp211 close to the hydrolysis center and provides a water molecule bounding on its carboxyl in the previous unhydrolyzing site. After the hydrolysis takes place and the product is excluded from the enzyme, the Asp211 comes back to its initial position. In summary, Asp211 acts as an elevator to transport outer water molecules into the hydrolysis site for every other glycosidic bond.

AB - OBJECTIVES: The investigation of the record of growth locked in dental enamel provides a unique opportunity to build a comprehensive picture of growth disruption episodes during childhood. This study presents a new methodological basis for the analysis of enamel growth disruptions (enamel hypoplasia) using incremental microstructures of enamel. METHODS: A three-dimensional technique based upon use of an Alicona 3D Infinite Focus imaging microscope and software is used to record developmental features in the enamel of human permanent mandibular lateral incisors of one individual from the Neolithic site of Catalhoyuk (Turkey). Using this new technique, perikymata are measured down the longitudinal axis of the crown from the incisal margin to the cervix and perikyma spacing profiles are constructed with this new technique. A mathematical basis for the detection of spacing anomalies, which serve as indicators of enamel hypoplasia is presented based upon these profiles. RESULTS: Three clearly delineated defects were identified visually, then matched and confirmed metrically using the enamel surface and perikyma spacing profiles. DISCUSSION: Human growth has often been used as an indicator of health in past societies because of developmental sensitivity to fluctuations in nutritional status and disease load. Hence, standardization of furrow-form defect identification is of crucial importance for reducing the amount of current subjectivity in the determination of a threshold for the identification of defects among individuals of past populations. The method presented here, which is based on microscopic images of the tooth crown as well as recorded measurements of incremental structures, represents a combined visual-metric approach using LOWESS residuals, and as such provides a substantial advancement to previous methods. It is therefore recommended that additional studies be carried out with this methodology to determine whether this method improves the reliability of enamel defect identification among individuals recovered from bioarchaeological contexts. PMID- 27696358 TI - The Movement Tracker: A Flexible System for Automated Movement Analysis in Invertebrate Model Organisms. AB - Phenotyping strategies in simple model organisms such as D. melanogaster and C. elegans are often broadly limited to growth, aging, and fitness. Recently, a number of physical setups and video tracking software suites have been developed to allow for accurate, quantitative, and high-throughput analysis of movement in flies and worms. However, many of these systems require precise experimental setups and/or fixed recording formats. We report here an update to the Parallel Worm Tracker software, which we termed the Movement Tracker. The Movement Tracker allows variable experimental setups to provide cross-platform automated processing of a variety of movement characteristics in both worms and flies and permits the use of simple physical setups that can be readily implemented in any laboratory. This software allows high-throughput processing capabilities and high levels of flexibility in video analysis, providing quantitative movement data on C. elegans and D. melanogaster in a variety of different conditions.

AB - The ability to assess the potential for gastrointestinal adverse events in a preclinical setting is a challenge in the development of new drugs, as the vast majority of in vivo research is conducted in rodent species lacking a vomiting reflex. The use of higher species capable of emesis is often limited by cost, technical experience, and relevant efficacy models to define a therapeutic index. Additionally, investigators should be mindful of ethical considerations when using more sentient species when an alternative in lower species is available. This unit describes the use of pica behavior in rodents as an alternative for evaluating emetic potential in vivo. After an acclimation period, the incidence of rats engaging in pica following the administration of a test article can be used to generate a dose-response curve of the pica behavior. When linked with an appropriate efficacy model, this allows compounds to be ranked based on therapeutic index. (c) 2016 by John Wiley & Sons, Inc. PMID- 27696360 TI - Automatic Dendritic Spine Quantification from Confocal Data with Neurolucida 360. AB - Determining the density and morphology of dendritic spines is of high biological significance given the role of spines in synaptic plasticity and in neurodegenerative and neuropsychiatric disorders. Precise quantification of spines in three dimensions (3D) is essential for understanding the structural determinants of normal and pathological neuronal function. However, this quantification has been restricted to time- and labor-intensive methods such as electron microscopy and manual counting, which have limited throughput and are impractical for studies of large samples. While there have been some automated software packages that quantify spine number, they are limited in terms of their characterization of spine structure. This unit presents methods for objective dendritic spine morphometric analysis by providing image acquisition parameters needed to ensure optimal data series for proper spine detection, characterization, and quantification with Neurolucida 360. These protocols will be a valuable reference for scientists working towards quantifying and characterizing spines. (c) 2016 by John Wiley & Sons, Inc.

AB - Animal models are crucial to the study of the neurobiological bases of psychiatric disorders, but schizophrenia is a particularly challenging disorder to model given the complexity and heavily verbal nature of its symptoms. This unit describes a developmental surgical rodent model of schizophrenia, the neonatal ventral hippocampal lesion (NVHL) model. This widely used model produces reliable behavioral abnormalities that are comparable to those observed in patients, as well as anatomical and neurophysiological disruptions in forebrain areas that are also implicated in schizophrenia. A brief background of the development and validity of the NVHL model is discussed here, along with detailed procedures for producing the model in rats. Critical issues particular to neonatal surgery are discussed, and representative histological and behavioral results are presented. (c) 2016 by John Wiley & Sons, Inc.

Most preclinical models use nicotine alone, although there are >7000 constituents present in tobacco smoke. The clinical literature suggests that cigarettes have a strong addictive potential, which is not paralleled in preclinical studies using nicotine alone. In order to address the gap between clinical and preclinical literature on tobacco dependence, cigarette smoke extracts containing tobacco constituents have been developed. This unit describes a procedure for producing an aqueous cigarette smoke extract (CSE) which animals readily self-administer. In addition, we describe how to make the apparatus for producing CSE and how to analyze the solution for nicotine content. (c) 2016 by John Wiley & Sons, Inc. PMID- 27696363 TI - Cerebral Cortex Electroporation to Study Projection Neuron Migration. AB - Brain electroporation is a rapid and powerful approach to study neuronal development. In particular, this technique has become a method of choice for studying the process of radial migration of projection neurons in the embryonic cerebral cortex. This method has considerably helped to describe in detail the different steps of radial migration and to characterize the molecular mechanisms controlling this process. Delineating the complexities of neuronal migration is critical to our understanding not only of normal cerebral cortex formation but also of neurodevelopmental disorders resulting from neuronal migration defects. Here, we describe in detail the protocols to perform in utero or ex vivo electroporation of progenitor cells in the ventricular zone of the cerebral cortex with the aim of studying the process of radial migration of projection neurons during embryonic development.

AB - OBJECTIVES: The purpose of this study is to conduct an analysis of ossification patterns in the distal femoral, proximal tibial, and proximal fibular epiphyses, and the patella. The results generated from this analysis will be compared with previous standards published by Elgenmark () and Garn et al. () to determine if clinical and skeletal age assessment standards should be updated for contemporary Americans. MATERIALS AND METHODS: Using the Pediatric Radiology Interactive Atlas (Patricia), a total of 1,317 epiphyses were scored for presence or absence from radiographs of 1,056 white individuals born in or after 1990. Statistical modeling of epiphyseal appearance was conducted for all major percentiles, including the 5th and 95th percentiles through logistic regression. RESULTS: Compared with Elgenmark () and Garn et al. (), our data suggest that the distal femoral and proximal tibial epiphyses show overall earlier ossification, while the proximal fibular epiphysis shows later ossification. When examining the pooled sex 50th percentile for our data, we found that ossification timing differences are 1.2 weeks earlier in the distal femoral epiphysis, 2.1 weeks earlier in the proximal tibial epiphysis, and 1.4 years later in the proximal fibular epiphysis. DISCUSSION: The epiphyses that appear early in life, for example the distal femoral epiphysis, require gestational age information to accurately estimate appearance times. There are considerable differences between the ossification timing patterns presented in this study and those of previous standards, which did not include gestational ages. Several factors may explain the observed differences in the epiphyses of the knee including: the availability of gestational age information, the analysis of longitudinal versus cross sectional data, differences in socioeconomic status and prenatal care, and secular change.

PMID- 27696366 TI - Five-year study of quality of life in myotonic dystrophy. AB - Background - Myotonic dystrophy type 1 (DM1) is the most common muscular dystrophy in adults. There is a complete lack of studies that assessed quality of life (QoL) trajectory during time in DM1 cohorts. Aim - To analyze changes of QoL in patients with DM1 during a 5-year follow-up period and to assess responsiveness of the SF-36 questionnaire. Patients and Method - At the baseline, this study comprised 84 DM1 patients, of whom 62 were retested after the mean period of 64.2 +/- 3.9 months. Severity of muscular weakness was assessed using the Muscular Impairment Rating Scale (MIRS). Patients completed Serbian version of the SF-36 questionnaire as a measure of health-related QoL. Results - After 5 years, MIRS score of our DM1 patients showed significant progression of 0.5 grade (P < 0.01). All mental subdomains, role physical, and total SF-36 scores significantly improved after 5 years (P < 0.01). Unexpectedly, worsening of muscular weakness from mild to severe was in association with improvement of QoL. Conclusion - QoL improved in our cohort of DM1 patients during a 5-year period despite the progression of the disease. SF-36 should be used with caution as a patient-reported outcome measure in DM1 clinical trials. PMID- 27696367 TI - Association of hepatitis B virus infection with decreased ischemic stroke. AB - OBJECTIVES: Inflammatory processes (both infections and autoimmune diseases) may cause endothelial dysfunction and arterial atherosclerosis, subsequently increasing the risk of acute ischemic stroke (AIS). In this investigation, we analyzed the association between hepatitis B virus (HBV) infection and AIS risk. METHODS: A Taiwan national insurance claims data set of 1,000,000 patients was used to extract 22,303 patients with HBV and 89,212 randomly selected sex- and age-matched controls from the beginning of 2000 to the end of 2006. Both groups were followed up until the appearance of AIS or the end of 2011. AIS risk was measured using the Cox proportional regression model. RESULTS: After adjusting for the relevant covariates, the HBV group exhibited a lower AIS risk (adjusted hazard ratio [aHR] = 0.77, 95% confidence interval [CI]: 0.66-0.89) compared with the controls at the end of follow-up. Under the condition of no comorbidities, patients with HBV had a lower AIS risk compared with the controls (aHR = 0.65, 95% CI: 0.48-0.87). In 3 age-stratified subgroups, HBV was correlated with a significantly diminished risk of AIS (age <= 49 years: aHR = 0.57, 95% CI: 0.39 0.82; age 50-64 years: aHR = 0.65, 95% CI: 0.53-0.80; age >= 65 years: aHR = 0.96, 95% CI: 0.76-1.23). CONCLUSION: HBV was correlated with a reduced risk of AIS development. Although a decrease in AIS risk was noted in the patients with HBV, preventing the development of AIS in this population warrants further attention. PMID- 27696368 TI - Subthalamic oscillatory activity in parkinsonian patients with off-period dystonia. AB - OBJECTIVES: The study was aimed to explore oscillatory activity in the subthalamic nucleus (STN) in Parkinson's disease (PD) with off-period dystonia, a type of levodopa-induced dyskinesias (LID). METHODS: Eighteen patients with PD who underwent STN DBS were studied. Nine patients had dyskinesia defined as the LID group and nine patients who did not present any sign of dyskinesia were defined as the control group. Microelectrode recordings in the STN together with electromyogram (EMG) were recorded. Spectral and coherence analyses were performed to study the neuronal oscillations in relation to limb muscles. RESULTS: Two hundred and fifteen neurons were identified. There were 39 neurons with tremor-frequency band (4-7 Hz) oscillation, 57 neurons with beta-frequency band (12-30 Hz, beta-FB) oscillation and 100 neurons without oscillation, and 19 neurons with very low-frequency band oscillation at a mean peak power of 1.2 +/- 0.5 Hz (LFB). These LFB oscillatory neurons (n = 15) were frequently significantly coherent with EMG of off-period dystonia. Notably, 89% (n = 17) neurons with LFB oscillation were found in the patients in the off-dystonia group. The age at onset of PD, duration of PD, and levodopa equivalent dose daily consumption were statistically different between two groups (P < 0.05). CONCLUSIONS: Subthalamic LFB oscillatory neurons seem to play an important role in the genesis of off-period dystonia in advanced PD. Clinical and demographic analyses confirmed that the earlier age at onset of PD, longer duration of PD, and levodopa exposure are important risk factors in the development of the type of LID.

AB - The comprehensive understanding of disassembly mechanism of amyloid fibrils requires nano-scale characterization of the mechanical properties of amyloid fibrils during the disassembly process. In this work, gemini surfactant C12 C6 C12 Br2 micelles were used as a probe to disassemble Abeta(1-40) fibrils. The microstructure evolution and nano-mechanical properties of Abeta(1-40) fibrils during the disassembly process were systematically investigated by the Peak Force Quantitative Nano-mechanical (PF-QNM) technique. The results show an obvious decrease in Young's modulus of mature fibrils with high beta-sheet contents (2.4 +/- 1.0 GPa) in comparison to the resulting peptide/surfactant complexes (1.1 +/- 0.8 GPa) with loose surface structures. Interestingly, the Young's modulus of spherical peptide/surfactant complexes on the core was more than 3 GPa. This strategy can be used as a standard protocol to investigate the interaction mechanism between amyloid fibrils and small molecules, which may open up new possibilities to explore the mechanism of relevant human diseases. PMID- 27696371 TI - Comprehensive reconstruction and in silico analysis of Aspergillus niger genome scale metabolic network model that accounts for 1210 ORFs. AB - Aspergillus niger is one of the most important cell factories for industrial enzymes and organic acids production. A comprehensive genome-scale metabolic network model (GSMM) with high quality is crucial for efficient strain improvement and process optimization. The lack of accurate reaction equations and gene-protein-reaction associations (GPRs) in the current best model of A. niger named GSMM iMA871, however, limits its application scope. To overcome these limitations, we updated the A. niger GSMM by combining the latest genome annotation and literature mining technology. Compared with iMA871, the number of reactions in iHL1210 was increased from 1,380 to 1,764, and the number of unique ORFs from 871 to 1,210. With the aid of our transcriptomics analysis, the existence of 63% ORFs and 68% reactions in iHL1210 can be verified when glucose was used as the only carbon source. Physiological data from chemostat cultivations, 13 C-labeled and molecular experiments from the published literature were further used to check the performance of iHL1210. The average correlation coefficients between the predicted fluxes and estimated fluxes from 13 C-labeling data were sufficiently high (above 0.89) and the prediction of cell growth on most of the reported carbon and nitrogen sources was consistent. Using the updated genome-scale model, we evaluated gene essentiality on synthetic and yeast extract medium, as well as the effects of NADPH supply on glucoamylase production in A. niger. In summary, the new A. niger GSMM iHL1210 contains significant improvements with respect to the metabolic coverage and prediction performance, which paves the way for systematic metabolic engineering of A. niger.

AB - BACKGROUND: Bacterial vaginosis (BV) is an infection that has a prevalence between 10% to 50% worlwide. BV results in an imbalance of the normal vaginal flora. Microorganisms associated with BV have been isolated from the normal flora of the male genital tract, and their presence could be related to the recurrence of BV after antibiotic treatment. Therefore, the treatment of sexual partners could decrease the recurrence of infection and possibly the burden of the disease. OBJECTIVES: To assess the effectiveness in women and the safety in men of concurrent antibiotic treatment for the sexual partners of women treated for BV. SEARCH METHODS: We searched the Cochrane Sexually Transmitted Infections Group Specialized Register (23 July 2016), CENTRAL (1991 to 23 July 2016), MEDLINE (1946 to 23 July 2016), Embase (1974 to 23 July 2016), LILACS (1982 to 23 July 2016), the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (23 July 2016), ClinicalTrials.gov (23 July 2016) and the Web of ScienceTM (2001 to 23 July 2016). We also handsearched conference proceedings, contacted trial authors and reviewed the reference lists of retrieved studies. SELECTION CRITERIA: Randomized controlled trials (RCTs) that compared the concurrent use of any antibiotic treatment with placebo, no intervention or any other intervention by the sexual partners of women treated for BV. DATA COLLECTION AND ANALYSIS: Three review authors independently assessed trials for inclusion, extracted data and assessed the risk of bias in the included studies. We resolved any disagreements through consensus. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS: Seven RCTs (1026 participants) met our inclusion criteria, and pharmaceutical industry funded four of these trials. Five trials (854 patients) compared any antibiotic treatment of sexual partners with placebo. Based on high quality evidence, antibiotic treatment does not increase the rate of clinical or symptomatic improvement in women during the first week (risk ratio (RR) 0.99, 95% confidence interval (CI) 0.96 to 1.03; 712 participants, four studies; RR 1.06, 95% CI 1.00 to 1.12; 577 patients, three studies, respectively), between the first and fourth week (RR 1.02, 95% CI 0.94 to 1.11; 590 participants, three studies; RR 0.93, 95% CI 0.84 to 1.03; 444 participants, two studies; respectively) or after the fourth week (RR 0.98, 95% CI 0.90 to 1.07; 572 participants, four studies; RR 1.03, 95% CI 0.90 to 1.17; 296 participants, two studies; respectively). Antibiotic treatment does not led to a lower recurrence during the first and fourth week (RR 1.28, 95% CI 0.68 to 2.43; 218 participants, one study; low quality evidence) or after the fourth week of treatment (RR 1.00, 95% CI 0.67 to 1.52; 372 participants, three studies; low quality evidence) in women, but increases the frequency of adverse events (most frequently gastrointestinal symptoms) reported by sexual partners (RR 2.55, 95% CI 1.55 to 4.18; 477 participants, three studies; low quality evidence). Two trials (172 participants) compared any antibiotic treatment for sexual partners with no intervention. When we compared it with no intervention, the effects of antibiotic treatment on recurrence rate after the fourth week (RR 1.71, 95% CI 0.65 to 4.55; 51 participants, one study), clinical improvement between the first and fourth week (RR 0.93, 95% CI 0.70 to 1.25; 152 participants, two studies) and symptomatic improvement after the fourth week (RR 0.66, 95% CI 0.39 to 1.11; 70 participants, one study) were imprecise and there were no differences between groups. We downgraded the quality of the evidence to low or very low. AUTHORS' CONCLUSIONS: High quality evidence shows that antibiotic treatment for sexual partners of women with BV, compared with placebo, does not increase the rate of clinical or symptomatic improvement during the first, between the first and fourth or after the fourth week into the women. Low quality evidence suggests that antibiotic treatment does not led to a lower recurrence rate during the first and fourth or after the fourth week of treatment into the women, but increases the frequency of adverse events reported by sexual partners. Finally, compared with no intervention, antibiotic treatment does not decrease the recurrence rate after the fourth week and does not increase the frequency of clinical or symptomatic improvement between the first and fourth or after the fourth week into the women, respectively. PMID- 27696373 TI - Delirium After Spine Surgery in Older Adults: Incidence, Risk Factors, and Outcomes. AB - OBJECTIVES: To characterize the incidence, risk factors, and consequences of delirium in older adults undergoing spine surgery. DESIGN: Prospective observational study. SETTING: Academic medical center. PARTICIPANTS: Individuals aged 70 and older undergoing spine surgery (N = 89). MEASUREMENTS: Postoperative delirium and delirium severity were assessed using validated methods, including the Confusion Assessment Method (CAM), CAM for the Intensive Care Unit, Delirium Rating Scale-Revised-98, and chart review. Hospital-based outcomes were obtained from the medical record and hospital charges from data reported to the state. RESULTS: Thirty-six participants (40.5%) developed delirium after spine surgery, with 17 (47.2%) having purely hypoactive features. Independent predictors of delirium were lower baseline cognition, higher average baseline pain, more intravenous fluid administered, and baseline antidepressant medication. In adjusted models, the development of delirium was independently associated with higher quintile of length of stay (odds ratio (OR) = 3.66, 95% confidence interval (CI) = 1.48-9.04, P = .005), higher quintile of hospital charges (OR = 3.49, 95% CI = 1.35-9.00, P = .01), and lower odds of discharge to home (OR = 0.22, 95% CI = 0.07-0.69, P = .009). Severity of delirium was associated with higher quintile of hospital charges and lower odds of discharge to home. CONCLUSION: Delirium is common after spine surgery in older adults, and baseline pain is an independent risk factor. Delirium is associated with longer stay, higher charges, and lower odds of discharge to home. Thus, prevention of delirium after spine surgery may be an important quality improvement goal.

PMID- 27696375 TI - Establishing and prioritizing research questions for the treatment of alopecia areata: the Alopecia Areata Priority Setting Partnership. AB - BACKGROUND: Alopecia areata (AA) is a common hair loss disorder that results in patchy to complete hair loss. Many uncertainties exist around the most effective treatments for this condition. OBJECTIVES: To identify uncertainties in AA management and treatment that are important to both service users (people with hair loss, carers and relatives) and healthcare professionals. METHODS: An AA priority setting partnership was established between patients, their carers and relatives, and healthcare professionals to identify the most important uncertainties in AA. The methodology of the James Lind Alliance was followed to ensure a balanced, inclusive and transparent process. RESULTS: In total, 2747 treatment uncertainties were submitted by 912 participants, of which 1012 uncertainties relating to AA (and variants) were analysed. Questions were combined into 'indicative uncertainties' following a structured format. A series of ranking exercises further reduced this list to a top 25 that were taken to a final prioritization workshop where the top 10 priorities were agreed. CONCLUSIONS: We present the top 10 research priorities for AA to guide researchers and funding bodies to support studies important to both patients and clinicians. PMID- 27696376 TI - Evaluation of outcome after cardiomyotomy for achalasia using the Chicago classification. AB - BACKGROUND: Achalasia can be subdivided into manometric subtypes according to the Chicago classification. These subtypes are proposed to predict outcome after treatment. This hypothesis was tested using a database of patients who underwent laparoscopic Heller's cardiomyotomy with anterior fundoplication. METHODS: All patients who underwent Heller's cardiomyotomy for achalasia between June 1993 and March 2015 were identified from an institutional database. Manometry tracings were retrieved and re-reported according the Chicago classification. Outcome was assessed by a postal questionnaire, and designated a success if the modified Eckardt score was 3 or less, and the patient had not undergone subsequent surgery or pneumatic dilatation. Difference in outcome after cardiomyotomy was analysed with a mixed-effects logistic regression model. RESULTS: Sixty, 111 and 24 patients had type I, II and II achalasia respectively. Patients with type III achalasia were more likely to be older than those with type I or II (mean age 63 versus 50 and 49 years respectively; P = 0.001). Some 176 of 195 patients returned questionnaires after surgery. Type III achalasia was less likely to have a successful outcome than type II (odds ratio (OR) 0.38, 95 per cent c.i. 0.15 to 0.94; P = 0.035). There was no significant difference in outcome between types I and II achalasia (II versus I: OR 0.87, 0.47 to 1.60; P 0.663). The success rate at 3-year follow-up was 69 per cent (22 of 32) for type I, 66 per cent (33 of 50) for type II and 31 per cent (4 of 13) for type III. CONCLUSION: Type III achalasia is a predictor of poor outcome after cardiomyotomy. There was no difference in outcome between types I and II achalasia. PMID- 27696377 TI - Responsiveness of 8 Patient-Reported Outcomes Measurement Information System (PROMIS) measures in a large, community-based cancer study cohort. AB - BACKGROUND: The Patient-Reported Outcomes Measurement Information System (PROMIS) was a National Institutes of Health-funded initiative to develop measures of symptoms and function. Responsiveness is the degree to which a measure can detect underlying changes over time. The objective of the current study was to document the responsiveness of 8 PROMIS measures in a large, population-based cancer cohort. METHODS: The Measuring Your Health study recruited 2968 patients who were diagnosed with 1 of 7 cancers between 2010 and 2012 through 4 Surveillance, Epidemiology, and End Results registries. Participants completed a baseline survey (6-13 months after diagnosis) and a 6-month follow-up survey. Changes in 8 PROMIS scores were compared with global ratings of transition, changes in performance status, and clinical events. RESULTS: Measures were responsive to 6 month declines and improvements in performance status with small to large effect sizes (ES) (Cohen d = 0.34-0.71; P < .01). Mean changes and effect sizes were larger for participants who reported declines compared with those who reported improvements. Small-to-medium ES were observed in patients who reported being "a little" worse (d = 0.31-0.56), and medium-to-large ES were observed in those who reported being "a lot" worse (d = 0.53-0.72). Hospitalized participants reported significant score increases, resulting in worsening of pain (d = 0.51), fatigue (d = 0.35), and depression (d = 0.57; all P < .01). Cancer recurrence and progression were associated with smaller increases in pain, fatigue, and sleep disturbance (d = 0.22-0.27). CONCLUSIONS: The current results indicated that all 8 PROMIS measures were sensitive to patient-perceived worsening and improvement and to major clinical events. These findings will be able to inform the design and interpretation of future research studies and clinical initiatives administering PROMIS measures. Cancer 2017;123:327-335.

AB - BACKGROUND: Liver resection is effective for hepatocellular carcinoma (HCC) exceeding the Milan criteria in selected patients. However, the benefit of anatomical resection (AR) versus non-anatomical resection (NAR) has not been clarified in this patient subgroup. This study aimed to compare outcomes between AR and NAR for HCC exceeding the Milan criteria. METHODS: Data on consecutive patients with HCC exceeding the Milan criteria who underwent liver resection with curative intent over a recent 6-year interval were extracted from a prospective single-centre HCC database and examined retrospectively. The postoperative outcomes of patients were compared before and after propensity score matching. RESULTS: Some 546 patients were included: 264 in the AR and 282 in the NAR group. In the original cohort, the AR group contained more patients with larger tumours, multiple tumours, macroscopic portal vein tumour thrombi, incomplete tumour capsules and microscopic vascular invasion. After propensity score matching, 177 pairs of patients were selected. The baseline data, including liver function and tumour burden, were similar in the matched groups. The 3-year recurrence-free survival rate was comparable between the matched NAR and AR groups (36.5 versus 28.5 per cent; P = 0.448). Similar results were observed for 3-year overall survival (57.5 versus 50.3 per cent; P = 0.385), recurrence patterns and early recurrence rates (57.6 per cent versus 59.9 per cent; P = 0.712). CONCLUSION: AR and NAR achieved favourable and similar outcomes for HCC exceeding the Milan criteria in selected patients. PMID- 27696381 TI - Climate change and the epidemiology of selected tick-borne and mosquito-borne diseases: update from the International Society of Dermatology Climate Change Task Force. AB - Climate change refers to variation in the climate of a specific region or globally over time. A change has been reported in the epidemiology of tick- and mosquito-borne diseases in recent decades. Investigators have postulated that this effect may be associated with climate change. We reviewed the English language literature describing changes in the epidemiology of specific tick- and mosquito-borne diseases, including the tick-borne diseases of Lyme disease, tularemia, Crimean-Congo hemorrhagic fever, Mediterranean spotted fever, and Rocky Mountain spotted fever and the mosquito-borne diseases of dengue, malaria, West Nile virus infection, Ross River virus disease, and Barmah Forest virus disease. We postulate that the changing epidemiology of tick- and mosquito-borne diseases is related to climate change. PMID- 27696380 TI - Phase 2 study of dasatinib in patients with alveolar soft part sarcoma, chondrosarcoma, chordoma, epithelioid sarcoma, or solitary fibrous tumor. AB - BACKGROUND: Alveolar soft part sarcoma (ASPS), chondrosarcoma (CS), chordoma, epithelioid sarcoma, and solitary fibrous tumor (SFT) are malignant tumors that are relatively resistant to chemotherapy and for which more effective drug therapy is needed. METHODS: The 5 listed subtypes were enrolled into a single indolent sarcoma cohort in a phase 2 study of dasatinib using a Bayesian continuous monitoring rule for enrollment. The primary objective was to estimate the 6-month progression-free survival (PFS) rate according to the Choi criteria with a target of >=50%. Cross-sectional imaging was performed before the start of treatment, every 2 months for 6 months, and then every 3 months during treatment. The 2- and 5-year survival rates were determined. RESULTS: One hundred sixteen patients were enrolled within 45 months, and 109 began treatment with dasatinib. The 6-month PFS rate and the median PFS were 48% and 5.8 months, respectively. The PFS rate at 6 months was highest with ASPS (62%) and lowest with SFT (30%). More than 10% of the patients with ASPS, CS, or chordoma had stable disease for more than 1 year. Collectively, for all 5 subtypes, the 2- and 5-year overall survival rates were 44% and 13%, respectively. An objective response was observed in 18% of the patients with CS or chordoma. CONCLUSIONS: Dasatinib failed to achieve control of sarcoma growth for at least 6 months in more than 50% of the patients in this trial according to the Choi tumor response criteria. An objective tumor response and prolonged stable disease was observed in >10% of patients with CS or chordoma. Cancer 2017;90-97. (c) 2016 American Cancer Society. PMID- 27696382 TI - Prognostic impact of extracapsular lymph node involvement after neoadjuvant therapy and oesophagectomy. AB - BACKGROUND: The significance of extracapsular lymph node involvement (LNI) is unclear in patients with oesophageal cancer who have undergone neoadjuvant treatment followed by oesophagectomy. The aim of this study was to assess the incidence and prognostic significance of extracapsular LNI in a large multicentre series of consecutive patients with oesophageal cancer treated by neoadjuvant chemotherapy or chemoradiotherapy and surgery. METHODS: Data from a consecutive series of patients treated at two European centres were analysed. All patients with squamous cell carcinoma or adenocarcinoma of the oesophagus or gastro oesophageal junction, who received neoadjuvant chemotherapy or chemoradiation followed by transthoracic oesophagectomy and two-field lymphadenectomy with curative intent, were included. RESULTS: Between January 2000 and September 2013, 704 patients underwent oesophagectomy after neoadjuvant therapy. A median of 28 (range 5-77) nodes per patient was recovered. Some 347 patients (49.3 per cent) had no LNI (ypN0). Of the remaining 357 patients (50.7 per cent) with LNI (ypN1 3), extracapsular LNI was found in 190 (53.2 per cent). Five-year overall survival rates were 62.7 per cent for patients with N0 disease, 44.9 per cent for patients without extracapsular spread and 14.0 per cent where extracapsular LNI was identified (P < 0.001). Multivariable analyses demonstrated the presence of extracapsular LNI as an independent prognostic factor. CONCLUSION: The presence of extracapsular LNI after neoadjuvant therapy carries a poor prognosis. PMID- 27696383 TI - Rab11 collaborates E-cadherin to promote collective cell migration and indicates a poor prognosis in colorectal carcinoma. AB - BACKGROUND: Collective cell migration, whereby the cell-cell contacts such as E cadherin are maintained during migration, has only recently emerged, and its detailed mechanisms are still unclear. In this study, the role of Rab11, which functions in recycling endosomes, and its relationship to E-cadherin in colorectal carcinoma were identified, and the role of Rab11 in the collective cell migration of colon cancer cells was clarified. MATERIALS AND METHODS: A total of 107 patients with surgically resected colorectal carcinoma were enrolled in this immunohistochemical study. Relationships between the overexpression of Rab11 and E-cadherin and survival were evaluated. The cell biology of Rab11 overexpression or knock-down in HT-29 colon cells was studied. RESULTS: The expression of Rab11 and E-cadherin was not correlated with the stage of cancer or lymph node metastasis. However, the overall survival was poor in the group of 67 patients with duo-positive Rab11 and E-cadherin expression compared to the group (40 patients) without dual-positive expression (P = 0.038). Rab11 was demonstrated to have a physical interaction with E-cadherin, and overexpression of Rab11 was found to promote collective cell migration through the increased distribution of E-cadherin, which enhanced cell-cell connections. In addition, Rac1 activation and matrix metalloproteinase-2 expressions were upregulated upon Rab11 expression. CONCLUSIONS: This study demonstrated that Rab11 and E-cadherin expressions are indicators of poor survival time in colorectal carcinoma, but that Rab11 overexpression may contribute to increased collective cell invasion in colorectal carcinoma. PMID- 27696378 TI - Probiotics, fibre and herbal medicinal products for functional and inflammatory bowel disorders. AB - : Functional bowel disorders (FBD), mainly irritable bowel syndrome (IBS) and functional constipation (FC, also called chronic idiopathic constipation), are very common worldwide. Inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease, although less common, has a strong impact on patients' quality of life, as well as being highly expensive for our healthcare. A definite cure for those disorders is still yet to come. Over the years, several therapeutic approaches complementary or alternative to traditional pharmacological treatments, including probiotics, prebiotics, synbiotics, fibre and herbal medicinal products, have been investigated for the management of both groups of diseases. However, most available studies are biased by several drawbacks, including small samples and poor methodological quality. Probiotics, in particular Saccharomyces boulardii and Lactobacilli (among which Lactobacillus rhamnosus), synbiotics, psyllium, and some herbal medicinal products, primarily peppermint oil, seem to be effective in ameliorating IBS symptoms. Synbiotics and fibre seem to be beneficial in FC patients. The probiotic combination VSL#3 may be effective in inducing remission in patients with mild-to-moderate ulcerative colitis, in whom Escherichia coli Nissle 1917 seems to be as effective as mesalamine in maintaining remission. No definite conclusions can be drawn as to the efficacy of fibre and herbal medicinal products in IBD patients due to the low number of studies and the lack of randomized controlled trials that replicate the results obtained in the individual studies conducted so far. Thus, further, well-designed studies are needed to address the real role of these therapeutic options in the management of both FBD and IBD.

PMID- 27696385 TI - Evaluation of a population-based approach to familial colorectal cancer. AB - As Newfoundland has the highest rate of familial colorectal cancer (CRC) in the world, we started a population-based clinic to provide colonoscopic and Lynch syndrome (LS) screening recommendations to families of CRC patients based on family risk. Of 1091 incident patients 51% provided a family history. Seventy-two percent of families were at low or intermediate-low risk of CRC and colonoscopic screening recommendations were provided by letter. Twenty-eight percent were at high and intermediate-high risk and were referred to the genetic counsellor, but only 30% (N = 48) were interviewed by study end. Colonoscopy was recommended more frequently than every 5 years in 35% of families. Lower family risk was associated with older age of proband but the frequency of screening colonoscopy recommendations varied across all age groups, driven by variability in family history. Twenty-four percent had a high MMR predict score for a Lynch syndrome mutation, and 23% fulfilled the Provincial Program criteria for LS screening. A population-based approach in the provision of colonoscopic screening recommendations to families at risk of CRC was limited by the relatively low response rate. A family history first approach to the identification of LS families was inefficient. PMID- 27696386 TI - Association of hepcidin-25 with survival after kidney transplantation. AB - BACKGROUND: Hepcidin is considered the master regulator of iron homoeostasis. Novel hepcidin antagonists have recently been introduced as potential treatment for iron-restricted anaemia. Meanwhile, serum hepcidin has been shown to be positively associated with cardiovascular disease and inversely with acute kidney injury. These properties may lead to contrasting effects, especially in renal transplant recipients (RTR), which are prone to cardiovascular diseases and graft failure. To date, the role of serum hepcidin in RTR is unknown. We, therefore, prospectively determined the association of serum hepcidin with risk of graft failure, cardiovascular mortality and all-cause mortality in RTR. MATERIALS AND METHODS: Serum hepcidin was assessed in an extensively phenotyped RTR cohort by dual-monoclonal sandwich ELISA specific immunoassay. Statistical analyses were performed using univariate linear regression followed by stepwise backward linear regression. Cox proportional hazard regression models were performed to determine prospective associations. RESULTS: We included 561 RTR (age 51 +/- 12 years). Mean haemoglobin (Hb) was 8.6 +/- 1.0 mM. Median [IQR] serum hepcidin was 7.2 [3.2-13.4] ng/mL. Mean estimated glomerular filtration rate was 47 +/- 16 mL/min/1.73 m2 . In univariate Cox regression analyses, serum hepcidin was not associated with risk of graft failure, cardiovascular mortality or all-cause mortality. Notably, after adjustment for high sensitivity C-reactive protein and ferritin, serum hepcidin became negatively associated with all-cause mortality (hazard ratio 0.89; 95% confidence interval 0.80-0.99, P = 0.03). CONCLUSIONS: In this study, we did not find an association between serum hepcidin and outcomes, that is graft failure, cardiovascular mortality or all-cause mortality. Based on our results, it is questionable whether serum hepcidin may be used to predict a beneficial effect of hepcidin antagonists. PMID- 27696387 TI - Cannabidiol as a new treatment for drug-resistant epilepsy in tuberous sclerosis complex. AB - OBJECTIVE: Tuberous sclerosis complex (TSC) is an autosomal-dominant genetic disorder with highly variable expression. The most common neurologic manifestation of TSC is epilepsy, which affects approximately 85% of patients, 63% of whom develop treatment-resistant epilepsy. Herein, we evaluate the efficacy, safety, and tolerability of cannabidiol (CBD), a nonpsychoactive compound derived from the marijuana plant, as an adjunct to current antiepileptic drugs in patients with refractory seizures in the setting of TSC. METHODS: Eighteen of the 56 patients who have enrolled in our current expanded-access study of cannabidiol for patients with treatment-resistant epilepsy carry a diagnosis of TSC. After an initial baseline period of 1 month, patients began treatment with CBD. The initial dose of 5 mg/kg/day was increased by 5 mg/kg/day every week up to a maximum dose of 50 mg/kg/day, if tolerated. Weekly seizure frequencies, percent change in seizure frequencies, and responder rates were calculated during the 2nd, 3rd, 6th, 9th, and 12th month of treatment with CBD. RESULTS: The median weekly seizure frequency during the baseline period was 22.0 (interquartile range [IQR] 14.8-57.4), which decreased to 13.3 (IQR 5.1-22.1) after 3 months of treatment with cannabidiol. The median percent change in total weekly seizure frequency was -48.8% (IQR -69.1% to -11.1%) after 3 months of treatment. The 50% responder rates over the course of the study were 50%, 50%, 38.9%, 50%, and 50% after 2, 3, 6, 9, and 12 months of treatment with CBD, respectively. In patients taking clobazam concurrently with CBD (n = 12), the responder rate after 3 months of treatment was 58.3%, compared to 33.3% in patients not taking clobazam (n = 6). Twelve (66.7%) of 18 patients in this study experienced at least one adverse event thought possibly related to CBD; the most common adverse events were drowsiness (n = 8, 44.4%), ataxia (n = 5, 27.8%), and diarrhea (n = 4, 22.2%). SIGNIFICANCE: Although double-blind, placebo-controlled trials are still necessary, these findings suggest that cannabidiol may be an effective and well-tolerated treatment option for patients with refractory seizures in TSC. PMID- 27696388 TI - The kerion: an angry tinea capitis. AB - Tinea capitis has a high incidence with a global changing pathogen distribution, making this condition a public health concern around the world. As the infection is initially asymptomatic, it is easily spread. Moreover, it is present in many fomites, including hairbrushes, pillows, and bedding. Prompt recognition and treatment is necessary for kerion, an inflammatory subtype characterized by tender boggy plaques with purulent drainage. Kerion is usually associated with infection by zoophilic dermatophytes, although other sources have been described. Treatment for this severe form of dermatophytic infection can be challenging. In addition to the use of topical treatments, oral administration of griseofulvin, terbinafine, itraconazole, or fluconazole is often required. Griseofulvin, the first-line treatment, may not completely eradicate pathogen colonization of the host and may contribute to reinfection and prevalence of infective but asymptomatic carriers. This review highlights new agents that are being evaluated for the treatment of kerion and typical tinea capitis, enhanced diagnostic criteria, and a grading system for kerion evaluation. PMID- 27696389 TI - Improvements in hepatitis B virus screening before rituximab therapy: A community based, safety-net hospital experience. AB - BACKGROUND: Individuals with chronic hepatitis B virus infection (HBV) or previously resolved HBV are at increased risk of HBV exacerbation or reactivation when they receive treatment with anti-CD20 monoclonal antibodies (against B lymphocyte antigen cluster of differentiation 20 [CD20], an activated glycosylated phosphoprotein) like rituximab (RTX). The objective of the current study was to evaluate the rates of appropriate HBV screening before patients started receiving RTX, at the initiation of HBV treatment, and during HBV flares among an underserved safety-net population. METHODS: In total, 244 consecutive adults who received treatment with RTX from 2006 to 2015 at an urban safety-net hospital were evaluated to determine appropriate HBV screening (HBV surface antigen [HBsAg] and HBV total core antibody [HBcAb]) before starting RTX. The initiation of prophylactic antiviral therapy and the development of HBV flares after starting RTX were evaluated. Predictors of appropriate HBV screening were evaluated using multivariate logistic regression models. RESULTS: Most patients were women (52.7%; n = 128) and of Hispanic ethnicity (30.7%; n = 74). Before starting RTX, 60.5% (n = 147) of patients received appropriate HBV screening. The HBV screening rates before RTX improved from 14.7% (2006-2009) to 74.7% (2010 2012), and to 87.1% (2013-2015; P < .01. Two of 7 (28.6%) HBsAg-positive patients who did not receive antiviral therapy experienced HBV flares and 1 died, and 2 of 27 patients (7.4%) HBcAb-positive/HBsAg-negative patients who did not receive antiviral therapy experienced HBV reactivation. No patient-specific or disease specific predictors of receiving HBV screening before RTX therapy were identified. CONCLUSIONS: Among adults receiving RTX therapy in a single community based hospital system, HBV screening rates were suboptimal, and 28.6% of HBsAg positive patients and 7.4% of HBsAg-negative/HBcAb-positive patients who did not receive antiviral treatment experienced HBV reactivation or flare.

AB - The importance of the family environment for the development of children with neurodisabilities is undisputed. The objective of this study is to describe how family environment has been measured in research on families of children with neurodisabilities, in order to support researchers and clinicians to select appropriate methods for use. A three-step approach was used and 13 measures of family environment were identified within 77 studies. Five measures were used most commonly across a majority of studies (n=50). The measures varied considerably in terms of theoretical background, content, subscales, and populations for which they were developed and validated. These measures were used with considerable variability between studies and with a limited range of research respondents, most typically the child's mother. Challenges, opportunities, and suggestions on how to improve the application of family environment measures in research are discussed. PMID- 27696392 TI - Interleukin-17 as a factor linking the pathogenesis of psoriasis with metabolic disorders. AB - Psoriasis is a systemic disease with numerous concomitant metabolic disorders. Apparently, T-helper 17 lymphocytes and interleukin (IL)-17 constitute an important element linking those disorders. The role of IL-17 has been confirmed by numerous studies, although it remains not completely understood, and the study results are controversial. Based on the studies performed so far, it is assumed that IL-17 contributes to development of atherosclerosis by means of: stimulation of production of proinflammatory compounds; induction of apoptosis of endothelial cells and heart muscle cells; stimulation of von Willebrand factor production; and induction of the matrix metalloproteinase-9 (atherosclerotic plaque rupture). On the other hand, IL-17 may exert protective activity due to inhibition of proatherogenic interferon-gamma and vascular cell adhesion molecule-1, and production of type I collagen by smooth muscle cells. The role of IL-17 in the pathogenesis of obesity is as important as other proinflammatory cytokines. On the other hand, its deficiency increases diet-induced obesity and accelerates adipose tissue accumulation. Although the role of IL-17A in the pathogenesis of metabolic disorders in humans remains controversial, introduction of anti-IL-17A treatments brings hope that development of metabolic disorders in patients with psoriasis may be inhibited. PMID- 27696391 TI - Prognostic impact of pretreatment cytogenetics in adult Philadelphia chromosome negative acute lymphoblastic leukemia in the era of minimal residual disease. AB - BACKGROUND: The introduction of novel prognostic factors such as minimal residual disease (MRD) and genomic profiling has led to the reevaluation of the role of cytogenetics and other conventional factors in risk stratification for acute lymphoblastic leukemia (ALL). METHODS: This study assessed the impact of baseline cytogenetics on the outcomes of 428 adult patients with Philadelphia chromosome negative ALL who were receiving frontline chemotherapy. Three hundred thirty patients (77%) were treated with hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone-based regimens, and 98 (23%) were treated with the augmented Berlin-Frankfurt-Munster regimen. RESULTS: The median age was 40 years (range, 13-86 years). One hundred eighty-six patients (43%) had diploid cytogenetics, 32 (7%) had complex cytogenetics (defined as >= 5 chromosomal abnormalities), 27 (6%) had low hypodiploidy/near-triploidy (Ho-Tr), 24 (6%) had high hyperdiploidy, and 24 (6%) had a mixed-lineage leukemia (MLL) rearrangement. Patients with an MLL rearrangement, Ho-Tr, or a complex karyotype had significantly worse relapse-free survival (RFS) and overall survival (OS) than the diploid group. According to a multivariate analysis including all the baseline characteristics and MRD status, Ho-Tr and a complex karyotype were independent predictive factors for worse RFS and OS. Furthermore, survival among all cytogenetic groups was similar, regardless of the treatment received. CONCLUSIONS: A complex karyotype and Ho-Tr are adverse prognostic factors for adults with ALL independently of the MRD status. These findings suggest that pretreatment cytogenetics remain a valuable prognostic tool in this population. Cancer 2017;123:459-467. (c) 2016 American Cancer Society. PMID- 27696393 TI - Increased protoporphyrin IX accumulation does not improve the effect of photodynamic therapy for actinic keratosis: a randomized controlled trial. AB - BACKGROUND: Photodynamic therapy (PDT) with methyl aminolaevulinate (MAL) is highly effective for treating actinic keratosis (AK) on the face/scalp, but less effective on the extremities. Insufficient accumulation of protoporphyrin IX (PpIX) may cause these inferior efficacy rates. However, it is possible to increase PpIX accumulation by extending the MAL application time and/or pretreating the skin with curettage. OBJECTIVES: To investigate whether increased PpIX accumulation improves the effect of MAL-PDT for AKs in a randomized intra individual study. METHODS: Twenty-two patients with 533 AKs on both hands were treated with MAL-PDT. To obtain different concentrations of PpIX, four symmetrical areas on each patient were randomly allocated to different regimens: (i) 3-h MAL application without prior curettage (3hC-); (ii) 3 h with curettage (3hC+); (iii) 21 h without curettage (21hC-); and (iv) 21 h with curettage (21hC+). Treatment efficacy was evaluated after 3 months, whereas PpIX fluorescence, pain and erythema were assessed during and after PDT. RESULTS: Extended MAL application with and without curettage increased PpIX accumulation significantly compared with the standard 3hC+ regimen (P = 0.001 and P = 0.002, respectively). However, the median total clearance rates did not improve accordingly: 3hC+ (55.0%), 21hC- (55.0%) and 21hC+ (53.6%). Conversely, insufficient PpIX accumulation in the 3hC- regimen led to a significantly lower clearance rate (33.3%) than the other regimens (P < 0.045). Furthermore, pain and erythema were correlated to PpIX accumulation. CONCLUSIONS: Increased PpIX accumulation does not improve the effect of MAL-PDT for AKs on the hands, but leads to worse adverse events. Different strategies are needed to improve PDT on the extremities. PMID- 27696394 TI - MicroRNA-494 Activation Suppresses Bone Marrow Stromal Cell-Mediated Drug Resistance in Acute Myeloid Leukemia Cells. AB - Acute myeloid leukemia (AML) is not sensitive to chemotherapy partially because of the protection of AML cells by mesenchymal stromal cells (MSCs). Our previous studies found that MSCs protected AML cells from apoptosis through the c-Myc dependent pathway. However, the mechanism by which MSCs regulate c-Myc in AML cells is still unknown. To elucidate the mechanism, we performed microRNA array analysis of AML cell lines and validated by TaqMan realtime PCR. The results showed that the expression of microRNA-494 (miR-494) in AML cells after coculture with MSCs was downregulated. Reporter gene analysis confirmed miR-494 as one of the regulators of c-Myc. In the coculture system, activation of miR-494 in AML cells suppressed proliferation and induced apoptosis of AML cells in vitro. After addition of mitoxantrone to the coculture system, the proliferation of AML cells with miR-494 activation was suppressed more than that of control cells. After subcutaneous injection of AML cell lines in combination with MSC, tumor growth was suppressed in mice injected with miR-494-overexpressing AML cells. The rate of tumor formation was even lower after mitoxantrone treatment in the miR-494 overexpressing group. Moreover, miR-494 activation resulted in a decrease of leukemic cell counts in peripheral blood (PB) and bone marrow, and prolonged survival in mice injected with miR-494-overexpressing AML cellls and MSCs compared to the control mice. Our results indicate that miR-494 suppresses drug resistance in AML cells by downregulating c-Myc through interaction with MSCs and that miR-494 therefore is a potential therapeutic target. J. Cell.

PMID- 27696396 TI - Atypical effects of incorporated surfactants on stability and dissolution properties of amorphous polymeric dispersions. AB - OBJECTIVES: To understand the impact of ionic and non-ionic surfactants on the dissolution and stability properties of amorphous polymeric dispersions using griseofulvin (GF) as a model for poorly soluble drugs. METHODS: Solid dispersions of the poorly water-soluble drug, griseofulvin (GF) and the polymers, poly(vinylpyrrolidone) (PVP) and poly(2-hydroxypropyl methacrylate) (PHPMA), have been prepared by spray drying and bead milling and the effect of the ionic and non-ionic surfactants, namely sodium dodecyl sulphate (SDS) and Tween-80, on the physico-chemical properties of the solid dispersions studied. KEY FINDINGS: The X ray powder diffraction data and hot-stage microscopy showed a fast re crystallisation of GF. While dynamic vapour sorption (DVS) measurements indicated an increased water uptake, slow dissolution rates were observed for the solid dispersions incorporating surfactants. The order by which surfactants free dispersions were prepared seemed critical as indicated by DVS and thermal analysis. Dispersions prepared by milling with SDS showed significantly better stability than spray-dried dispersions (drug remained amorphous for more than 6 months) as well as improved dissolution profile. CONCLUSIONS: We suggest that surfactants can hinder the dissolution by promoting aggregation of polymeric chains, however that effect depends mainly on how the particles were prepared. PMID- 27696395 TI - A phase 2 study of nanoparticle albumin-bound paclitaxel plus nedaplatin for patients with advanced, recurrent, or metastatic cervical carcinoma. AB - BACKGROUND: Nanoparticle albumin-bound paclitaxel (nab-paclitaxel) and nedaplatin (NDP) are used for the treatment of patients with cervical cancer. However, to the authors' knowledge, the use of this combination regimen among patients with advanced, recurrent, or metastatic cervical cancer has rarely been reported. METHODS: Patients with pathologically confirmed, stage IVB (FIGO staging 2009), recurrent or metastatic cervical cancer were eligible. Nab-paclitaxel at a dose of 175 mg/m2 plus NDP at a dose of 80 mg/m2 was administered intravenously every 3 weeks. The primary endpoint of the current study was the objective response rate (ORR). The secondary endpoints were progression-free survival, overall survival, and safety. RESULTS: A total of 27 patients were included (5 with late stage and 22 with recurrent or metastatic disease). The mean age of the patients was 48.26 +/- 9.21 years. Of these 27 patients, 25 had squamous cell carcinoma (92.6%). A total of 26 patients completed 92 cycles of chemotherapy, with an average of 3.4 cycles per patient. The ORR was 50.0% (13 of 26 patients). The overall survival was 16.6 months (95% confidence interval, 12.6-20.6 months) and the progression-free survival was 9.1 months (95% confidence interval, 2.4-15.8 months).The ORR of patients with an interval of >12 months from receipt of prior chemotherapy was significantly higher than that of those with a shorter interval (71.4% vs 25.0%; P = .034). The most common adverse effects reported were myelosuppression, gastrointestinal reactions, fatigue, and peripheral neuropathy. The incidence of grade 3 neutropenia was 33.3% (adverse effects were graded on a scale from 0 to 4 according to the National Cancer Institute's Common Terminology Criteria for Adverse Events [version 3.0]). The incidence of grade 3 thrombocytopenia and anemia was 7.4% and 18.5%, respectively. The incidence of grade 1 to 2 peripheral neuropathy was reported to be as high as 51.9%. No case of hypersensitivity was observed. CONCLUSIONS: The combination of nab-paclitaxel plus NDP for the treatment of patients with late-stage, recurrent, or metastatic cervical cancer appears to be active and tolerable.

AB - OBJECTIVES: Sinigrin is a major glucosinolate present in plants of the Brassicaceae family. Recently, sinigrin and its phytosome formulations have been investigated for its wound-healing actions, by our research group. The aim of this study was to demonstrate sinigrin drug release from its phytosome complex and also to determine whether the phytosome complex enhances the delivery of sinigrin into the skin when compared to free sinigrin. METHODS: In vitro Franz cell diffusion studies were performed on human abdominal skin. The morphology of the phytosome complex was examined by transmission electron microscopy. The in vitro drug release was determined using dialysis sacks. KEY FINDINGS: The in vitro drug release indicated a controlled and sustained release of sinigrin from the phytosome complex. Tape stripping results showed that the sinigrin-phytosome complex (0.5155 MUg/ml) statistically significantly enhanced the delivery of sinigrin into the stratum corneum-epidermis when compared to the free sinigrin (0.0730 MUg/ml). CONCLUSIONS: These results suggested the possibility of utilizing sinigrin-phytosome complex, to optimally deliver sinigrin to the skin which can be further used for various skin-related diseases including wound healing.

AB - Despite the level of supervision of inmates on death row, their suicide rate is higher than both the male prison population in the United States and the population of males over the age of 14 in free society. This study presents suicide data for death row inmates from 1978 through 2010. For the years 1978 through 2010, suicide rates on death row were higher than that for the general population of males over the age of 15 and for state prisons for all but 2 years.

PMID- 27696399 TI - Toluene inhalation in adolescent rats reduces flexible behaviour in adulthood and alters glutamatergic and GABAergic signalling. AB - Toluene is a commonly abused inhalant that is easily accessible to adolescents. Despite the increasing incidence of use, our understanding of its long-term impact remains limited. Here, we used a range of techniques to examine the acute and chronic effects of toluene exposure on glutameteric and GABAergic function, and on indices of psychological function in adult rats after adolescent exposure. Metabolomics conducted on cortical tissue established that acute exposure to toluene produces alterations in cellular metabolism indicative of a glutamatergic and GABAergic profile. Similarly, in vitro electrophysiology in Xenopus oocytes found that acute toluene exposure reduced NMDA receptor signalling. Finally, in an adolescent rodent model of chronic intermittent exposure to toluene (10 000 ppm), we found that, while toluene exposure did not affect initial learning, it induced a deficit in updating that learning when response-outcome relationships were reversed or degraded in an instrumental conditioning paradigm. There were also group differences when more effort was required to obtain the reward; toluene-exposed animals were less sensitive to progressive ratio schedules and to delayed discounting. These behavioural deficits were accompanied by changes in subunit expression of both NMDA and GABA receptors in adulthood, up to 10 weeks after the final exposure to toluene in the hippocampus, prefrontal cortex and ventromedial striatum; regions with recognized roles in behavioural flexibility and decision-making. Collectively, our data suggest that exposure to toluene is sufficient to induce adaptive changes in glutamatergic and GABAergic systems and in adaptive behaviour that may underlie the deficits observed following adolescent inhalant abuse, including susceptibility to further drug-use.

PMID- 27696405 TI - Effects of Hovenia dulcis Thunb. extract and methyl vanillate on atopic dermatitis-like skin lesions and TNF-alpha/IFN-gamma-induced chemokines production in HaCaT cells. AB - OBJECTIVES: Here, we hypothesized that Hovenia dulcis branch extract (HDB) and its active constituents ameliorates 2,4-dinitrochlorobenzene-induced atopic dermatitis (AD)-like skin lesions by modulating the T helper Th1/Th2 balance in NC/Nga mice and TNF-alpha- and IFN-gamma-induced production of thymus and activation-regulated chemokine (TARC) and macrophage-derived chemokine (MDC) in HaCaT cells. METHODS: HaCaT cells were stimulated by TNF-alpha/IFN-gamma in the presence of HDB and its constituents. TARC and MDC were measured by ELISA and RT PCR. For the in-vivo study, oral feeding of HDB was performed for 5 weeks with 2,4-dinitrochlorobenzene (DNCB) treatment every other day. The efficacy of HDB on parameters of DNCB-induced AD was evaluated morphologically, physiologically and immunologically. KEY FINDINGS: In-vitro studies showed that HDB and its constituents suppressed TNF-alpha/IFN-gamma-induced production of TARC and MDC in HaCaT cells by inhibiting MAPK signalling. In-vivo studies showed that HDB regulated immunoglobulin (Ig) E and immunoglobulin G2a (IgG2a) levels in serum and the expression of mRNA for Th1- and Th2-related mediators in skin lesions. Histopathological analyses revealed reduced epidermal thickness and reduced infiltration of skin lesions by inflammatory cells. CONCLUSION: These results suggest that HDB inhibits AD-like skin diseases by regulating Th1 and Th2 responses in NC/Nga mice and in HaCaT cells. PMID- 27696406 TI - Inhibition of human glioma cell proliferation by altered Bax/Bcl-2-p53 expression and apoptosis induction by Rhaponticum carthamoides extracts from transformed and normal roots. AB - OBJECTIVE: The objective of this study was to determine the cytotoxic effect and apoptotic activity of Rhaponticum carthamoides transformed root (TR) and root of soil-grown plant (NR) extracts in a human glioma primary cells. The effect of these root extracts on cell cycle arrest, mitochondrial membrane potential (DeltaPsim) and expression levels of apoptosis-related genes (Bcl-2, Bax and p53) were also examined. METHODS: Cytotoxic activity of root extracts was evaluated by MTT assay. Apoptosis and cell cycle were determined by flow cytometry. Expression levels of apoptosis-related gene were analysed by RT-PCR and Western blotting. DeltaPsim was examined by the use of JC-1 reagent. KEY FINDINGS: Rhaponticum carthamoides root extracts inhibit cell growth and induce apoptosis in a dose dependent manner in human glioma cells. The root extracts were found to up regulate the pro-apoptotic Bax protein and down-regulate the anti-apoptotic Bcl-2 protein, consequently increasing the ratios of Bax/Bcl-2 protein levels. Moreover, an increase of the p53 protein level and reduction of DeltaPsim in glioma cells were observed after treatment with NR and TR extracts. CONCLUSION: The results of this study may offer a new insight into the potential anticancer activity of R. carthamoides root extracts.

AB - OBJECTIVES: This study aims to investigate xanthine oxidase (XO) inhibitory activity and antihyperuricemic effects of Corylopsis coreana Uyeki flos extracts and the phytochemicals contained therein. METHODS: Ethanolic extracts of the plant were prepared, and the extraction process was optimized with respect to flavonoid content and XO inhibitory activity. The optimized ethanolic extract was tested for its XO inhibitory activity and antihyperuricemic effects in potassium oxonate-induced hyperuricemic mice. KEY FINDINGS: The 80% ethanolic extract showed the highest total flavonoid content and in-vitro XO inhibitory activity. In-vivo studies demonstrated that the optimized 80% ethanolic extract could inhibit hepatic XO activity and significantly alleviate hyperuricemia at a relatively low oral dose (50 mg/kg) in mice. Additionally, an in-vitro enzyme inhibition study showed that phytochemicals such as bergenin, isosalipurposide, quercetin and quercitrin may be the key constituents responsible for the observed antihyperuricemic effects of the extract. CONCLUSIONS: This study is the first report on the XO inhibitory and antihyperuricemic effects of C. coreana Uyeki flos extract, which can be therapeutically applied in treating hyperuricemia and gout. PMID- 27696408 TI - Widespread brain transcriptome alterations underlie the neuroprotective actions of dietary saffron. AB - Dietary saffron has shown promise as a neuroprotective intervention in clinical trials of retinal degeneration and dementia and in animal models of multiple CNS disorders, including Parkinson's disease. This therapeutic potential makes it important to define the relationship between dose and protection and the mechanisms involved. To explore these two issues, mice were pre-conditioned by providing an aqueous extract of saffron (0.01% w/v) as their drinking water for 2, 5 or 10 days before administration of the parkinsonian neurotoxin MPTP (50 mg/kg). Five days of saffron pre-conditioning provided the greatest benefit against MPTP-induced neuropathology, significantly mitigating both loss of functional dopaminergic cells in the substantia nigra pars compacta (p < 0.01) and abnormal neuronal activity in the caudate-putamen complex (p < 0.0001). RNA microarray analysis of the brain transcriptome of mice pre-conditioned with saffron for 5 days revealed differential expression of 424 genes. Bioinformatics analysis identified enrichment of molecular pathways (e.g. adherens junction, TNFR1 and Fas signaling) and expression changes in candidate genes (Cyr61, Gpx8, Ndufs4, and Nos1ap) with known neuroprotective actions. The apparent biphasic nature of the dose-response relationship between saffron and measures of neuroprotection, together with the stress-inducible nature of many of the up regulated genes and pathways, lend credence to the idea that saffron, like various other phytochemicals, is a hormetic stimulus, with functions beyond its strong antioxidant capacity. These findings provide impetus for a more comprehensive evaluation of saffron as a neuroprotective intervention. PMID- 27696409 TI - Brefeldin A-inhibited guanine nucleotide exchange protein 3 is localized in lysosomes and regulates GABA signaling in hippocampal neurons. AB - ADP-ribosylation factor (ARF) family of guanine-nucleotide-binding (G) proteins regulates organelle biogenesis, structure and trafficking. The functions of ARF proteins are tightly controlled by guanine nucleotide exchange factors (GEFs) containing a conserved SEC7 domain. Based on sequence similarity to brefeldin A inhibited guanine nucleotide exchange protein (BIG)/GBF of the Arf-GEF family, we recently identified BIG3 as a novel ARF GEF protein with a non-functional catalytic motif in the SEC7 domain. BIG3 is mainly expressed in pancreatic islets and brain. In the islets, depletion of BIG3 increases insulin and glucagon secretion because of enhanced biogenesis of insulin and glucagon granules in the absence of BIG3. Here, we investigate BIG3 functions in the brain, in particular its regulation of neurotransmitter release in hippocampal neurons from wild-type and BIG3 knockout mice. In hippocampal neurons, BIG3 is mainly localized in lysosomes, and its depletion selectively impairs inhibitory synaptic transmission. Our finding provides novel insights for a cell-specific function of BIG3 in regulating neurotransmission. PMID- 27696410 TI - Adult ciliary neurotrophic factor receptors help maintain facial motor neuron choline acetyltransferase expression in vivo following nerve crush. AB - Exogenous ciliary neurotrophic factor (CNTF) administration promotes the survival of motor neurons in a wide range of models. It also increases the expression of the critical neurotransmitter enzyme choline acetyltransferase (ChAT) by in vitro motor neurons, likely independent of its effects on their survival. We have used the adult mouse facial nerve crush model and adult-onset conditional disruption of the CNTF receptor alpha (CNTFRalpha) gene to directly examine the in vivo roles played by endogenous CNTF receptors in adult motor neuron survival and ChAT maintenance, independent of developmental functions. We have previously shown that adult activation of the CreER gene construct in floxed CNTFRalpha mice depletes this essential receptor subunit in a large subset of motor neurons (and all skeletal muscle, as shown in this study) but has no effect on the survival of intact or lesioned motor neurons, indicating that these adult CNTF receptors play no essential survival role in this model, in contrast to their essential role during embryonic development. Here we show that this same CNTFRalpha depletion does not affect ChAT labeling in nonlesioned motor neurons, but it significantly increases the loss of ChAT following nerve crush. The data suggest that, although neither motor neuron nor muscle CNTF receptors play a significant, nonredundant role in the maintenance of ChAT in intact adult motor neurons, the receptors become essential for ChAT maintenance when the motor neurons are challenged by nerve crush. Therefore, the data suggest that the receptors act as a critical component of an endogenous neuroprotective mechanism. J. Comp. Neurol. 525:1206 1215, 2017. (c) 2016 Wiley Periodicals, Inc.

AB - BIOSCREEN is a well-known simple tool for evaluating the transport of dissolved contaminants in groundwater, ideal for rapid screening and teaching. This work extends the BIOSCREEN model for the calculation of stable isotope ratios in contaminants. A three-dimensional exact solution of the reactive transport from a patch source, accounting for fractionation by first-order decay and/or sorption, is used. The results match those from a previously published isotope model but are much simpler to obtain. Two different isotopes may be computed, and dual isotope plots can be viewed. The dual isotope assessment is a rapidly emerging new approach for identifying process mechanisms in aquifers. Furthermore, deviations of isotope ratios at specific reactive positions with respect to "bulk" ratios in the whole compound can be simulated. This model is named BIOSCREEN-AT-ISO and will be downloadable from the journal homepage. PMID- 27696412 TI - A cross-sectional study of patient and provider perception of "cure" as a goal of cancer surgery. AB - BACKGROUND AND OBJECTIVE: Patients with advanced cancer often misperceive the purpose and likely effectiveness of cancer treatments. The aim of this study was to characterize patient and provider perceptions in the setting of surgery for potentially curable cancer. METHODS: One hundred and six patient-surgeon dyads were surveyed about their expectations for upcoming surgery. Items scored using a Likert scale were compared using the Wilcoxon signed-rank test. RESULTS: Patients and surgeons reported excellent communication and shared decision-making. Patients more often than surgeons perceived that surgery was "Likely" or "Very Likely" to cure their cancer (86.0% vs. 72.0%, P = 0.011), extend their lives (94.0% vs. 82.0%, P = 0.007), and relieve cancer-related symptoms (65.0% vs. 35.0%, P < 0.001). Patients less often felt that surgery would be associated with complications (33.0% vs. 48.0%, P = 0.016). Over half (53.9%) of patients believed that they were more likely to experience surgical cancer cure compared with someone else with the same diagnosis while 70.8% of surgeons declared a patient's relative chances of surgical cure "the same." CONCLUSIONS: Patients with resectable lung and gastrointestinal cancers have more optimistic perceptions about the outcomes of an upcoming surgery than their surgeons, even in a setting of good communication and shared decision-making.

AB - The effects of Quaternary climatic oscillations on the demography of organisms vary across regions and continents. In taxa distributed in Europe and North America, several paradigms regarding the distribution of refugia have been identified. By contrast, less is known about the processes that shaped the species' spatial genetic structure in areas such as the Himalayas, which is considered a biodiversity hotspot. Here, we investigated the phylogeographic structure and population dynamics of Primula tibetica by combining genomic phylogeography and species distribution models (SDMs). Genomic data were obtained for 293 samples of P. tibetica using restriction site-associated DNA sequencing (RADseq). Ensemble SDMs were carried out to predict potential present and past distribution ranges. Four distinct lineages were identified. Approximate Bayesian computation analyses showed that each of them have experienced both expansions and bottlenecks since their divergence, which occurred during or across the Quaternary glacial cycles. The two lineages at both edges of the distribution were found to be more vulnerable and responded in different ways to past climatic changes. These results illustrate how past climatic changes affected the demographic history of Himalayan organisms. Our findings highlight the significance of combining genomic approaches with environmental data when evaluating the effects of past climatic changes.

AB - A challenge in implementation of sensitive HPV-based screening is limiting unnecessary referrals to colposcopic biopsy. We combined two commonly recommended triage methods: partial HPV typing and "reflex" cytology, evaluating the possibility of automated cytology. This investigation was based on 1,178 exfoliated cervical specimens collected during the enrollment phase of The Study to Understand Cervical Cancer Early Endpoints and Determinants (SUCCEED, Oklahoma City, OK). We chose a colposcopy clinic population to maximize number of outcomes, for this proof-of-principle cross-sectional study. Residual aliquots of PreservCyt were HPV-typed using Linear Array (LA, Roche Molecular Systems, Pleasanton, CA). High-risk HPV typing data and cytologic results (conventional and automated) were used jointly to predict risk of histologically defined >=CIN2. We developed a novel computer algorithm that uses the same optical scanning features that are generated by the FocalPoint Slide Profiler (BD, Burlington, NC). We used the Least Absolute Shrinkage and Selection Operator (LASSO) method to build the prediction model based on a training dataset (n = 600). In the validation set (n = 578), for triage of all HPV-positive women, a cytologic threshold of >=ASC-US had a sensitivity of 0.94, and specificity of 0.30, in this colposcopy clinic setting. When we chose a threshold for the severity score (generated by the computer algorithm) that had an equal specificity of 0.30, the sensitivity was 0.91. Automated cytology also matched >=ASC-US when partial HPV typing was added to the triage strategy, and when we re defined cases as >=CIN3. If this strategy works in a prospective screening setting, a totally automated screening and triage technology might be possible.

AB - The wine industry is responsible for the production of million tons of waste, such as grape skin, stalk, sludge and seeds, which can be considered inexpensive sources of phenolic compound owing to incomplete extraction during wine production. Phenolic compounds, also called polyphenols, comprise the most abundant bioactive compounds in grape and are recognized by their antioxidant and antimicrobial potential. Because of their functional properties, extracts obtained from grape wastes, which are rich in phenolic compounds, can be employed in the development of many products, ranging from medical to food applications, decreasing the growth of spoilage and pathogenic microorganisms and inhibiting lipid oxidation. These characteristics are motivating the research for alternative sources of natural antioxidant and antimicrobial agents, aimed at decreasing the use of artificial additives, which have been associated with some toxic effects. This article provides a review of the use of grape by-product extracts and their bioactive compounds as natural antioxidant and antimicrobial agents in food products.

AB - Behavioural observations in the field of male Mediterranean damselfish Chromis chromis were combined with molecular analyses, using bi-parentally and maternally inherited markers, to investigate reproductive success patterns of alternative reproductive tactics (ARTs) in terms of number of eggs sired and number of females contributing to each nest. Cuckoldry was observed in every nest sampled, with at least two and up to seven sneaker males per nest. The nesting male, however, always significantly fertilized the greater number of eggs (on average 49%) in each clutch, whereas each sneaker fertilized around 7% of the clutch. The average number of females whose eggs were fertilized by nesting males was 6.76 (range 2-13), while each sneaker on average fertilized the eggs of 1.74 (range 1 8) females. Using this sibship reconstruction, some of the factors involved in the regulation of the dynamic equilibrium of reproductive success were investigated between the two ARTs shown by C. chromis males. Results show that the sneakers' reproductive success was positively linked to egg clutch size; the density of individuals in the nesting area negatively affected the size of egg clutches; the rate of defence behaviours performed by nesting males negatively influenced the number of females contributing to each nest. PMID- 27696418 TI - Impact of a novel synbiotic supplementation during gestation and lactation on immune responses in the Swiss albino mice offspring. AB - BACKGROUND: Prebiotics from various regularly consumed cereals and novel substrates are currently being utilised as functional foods. The aim of this study was to determine the effect of synbiotic, formulated with prebiotic extracted from natural resources like green gram (Vigna radiata) along with probiotic Lactobacillus rhamnosus GG (LGG) in modulating immune responses in the offspring when supplemented during gestation and lactation. RESULTS: Synbiotic supplementation was effective in improving cell mediated immunity and humoral immunity among F0 dams. Among F1 pups (F1 Syn + and F1 Syn-), synbiotic supplementation showed significantly heightened (P < 0.05) splenocyte proliferation, increased interleukin-10, interferon gamma and interleukin-17 responses, leucocyte phagocytic ability and increased secretory-immunoglobulin A. However, four-fold increase in IgG titres to Hepatitis-B vaccine was observed only in those mice that were supplemented with synbiotic postweaning (F1 Syn+). CONCLUSION: Synbiotic supplementation to pregnant dams affected the offspring's cellular and mucosal immunity favorably. However, IgG response to Hepatitis-B vaccine was influenced positively only when the supplementation was extended to the offsprings in the post weaning period. (c) 2016 Society of Chemical Industry. PMID- 27696417 TI - Apoplastic recognition of multiple candidate effectors from the wheat pathogen Zymoseptoria tritici in the nonhost plant Nicotiana benthamiana. AB - The fungus Zymoseptoria tritici is a strictly apoplastic, host-specific pathogen of wheat leaves and causal agent of septoria tritici blotch (STB) disease. All other plants are considered nonhosts, but the mechanism of nonhost resistance (NHR) to Z. tritici has not been addressed previously. We sought to develop Nicotiana benthamiana as a system to study NHR against Z. tritici. Fluorescence microscopy and quantitative reverse transcription polymerase chain reactions were used to establish the interaction between Z. tritici and N. benthamiana. Agrobacterium-mediated transient expression was used to screen putative Z. tritici effector genes for recognition in N. benthamiana, and virus-induced gene silencing (VIGS) was employed to determine the role of two receptor-like kinases (RLKs), NbBAK1 and NbSOBIR1, in Z. tritici effector recognition. Numerous Z. tritici putative effectors (14 of 63 tested) induced cell death or chlorosis in N. benthamiana. For most, phenotypes were light-dependent and required effector secretion to the leaf apoplastic space. Moreover, effector-induced host cell death was dependent on NbBAK1 and NbSOBIR1. Our results indicate widespread recognition of apoplastic effectors from a wheat-infecting fungal pathogen in a taxonomically distant nonhost plant species presumably by cell surface immune receptors. This suggests that apoplastic recognition of multiple nonadapted pathogen effectors may contribute to NHR. PMID- 27696419 TI - Immune-affinity monolithic array with chemiluminescent detection for mycotoxins in barley. AB - BACKGROUND: Mycotoxins are produced by fungi as secondary metabolites. They often multi-contaminate food and feed commodities posing a health risk to humans and animals. Fast and easy multiplex screening could be thought as a useful tool for detection of multi-contaminated food and feed commodities. RESULTS: A highly sensitive immune-affinity monolithic arrays for detecting the mycotoxins zearalenone, deoxynivalenol, T-2 toxin, HT-2 toxin, aflatoxins, ochratoxin A, and fumonisin B1 were fabricated using UV induced co-polymerisation. The mycotoxin antibodies firstly reacted with functional monomer to form antibody/functional monomer bio-conjugates. Subsequently, the antibody/functional monomer bio conjugates co-polymerised with cross-linker to form mycotoxins immune-affinity arrays. With optimal fabrication conditions, all mycotoxin immune-affinity monolithic arrays exhibited a linear response spanning three orders of magnitude. And the immune-affinity monolithic array has a low detection limit and has a good uniformity (intra-assay CV, and inter-assay CV both <8%). CONCLUSION: The fabricated mycotoxin immune-affinity monolithic arrays were proved as a sensitive, stable and economical tool in real food samples detection. Moreover, the mycotoxin immune-affinity monolithic arrays would be able to minimise manipulation steps: add samples and enzyme labelled mycotoxins, and detect CL signals.

AB - KEY POINTS: In human skeletal muscles, the current view is that the capacity for mitochondrial energy production, and thus endurance capacity, is set by the mitochondria volume. However, increasing the mitochondrial inner membrane surface comprises an alternative mechanism for increasing the energy production capacity. In the present study, we show that mitochondrial inner membranes in leg muscles of endurance-trained athletes have an increased ratio of surface per mitochondrial volume. We show a positive correlation between this ratio and whole body oxygen uptake and muscle fibre mitochondrial content. The results obtained in the present study help us to understand modulation of mitochondrial function, as well as how mitochondria can increase their oxidative capacity with increased demand. ABSTRACT: Mitochondrial energy production involves the movement of protons down a large electrochemical gradient via ATP synthase located on the folded inner membrane, known as cristae. In mammalian skeletal muscle, the density of cristae in mitochondria is assumed to be constant. However, recent experimental studies have shown that respiration per mitochondria varies. Modelling studies have hypothesized that this variation in respiration per mitochondria depends on plasticity in cristae density, although current evidence for such a mechanism is lacking. In the present study, we confirm this hypothesis by showing that, in human skeletal muscle, and in contrast to the current view, the mitochondrial cristae density is not constant but, instead, exhibits plasticity with long-term endurance training. Furthermore, we show that frequently recruited mitochondria-enriched fibres have significantly increased cristae density and that, at the whole-body level, muscle mitochondrial cristae density is a better predictor of maximal oxygen uptake rate than muscle mitochondrial volume. Our findings establish an elevating mitochondrial cristae density as a regulatory mechanism for increasing metabolic power in human skeletal muscle. We propose that this mechanism allows evasion of the trade-off between cell occupancy by mitochondria and other cellular constituents, as well as improved metabolic capacity and fuel catabolism during prolonged elevated energy requirements. PMID- 27696422 TI - Rate of new findings in diagnostic office bronchoscopy. AB - OBJECTIVES: Awake Flexible Tracheobronchoscopy (FTB) is an alternative to rigid bronchoscopy or sedated flexible bronchoscopy and allows an awake examination of the tracheobronchial tree. We hypothesized that the ability to perform office bronchoscopy as the need arises during a clinic visit would lead to a high rate of previously undiagnosed and clinically relevant findings. This study reports the rate and nature of such findings for this procedure at our institution. STUDY DESIGN: Retrospective chart review. METHODS: The records of 127 adult patients evaluated at the voice and swallowing disorders clinic between June of 2012 and January of 2015 were reviewed. New findings were defined as new pathology visualized during FTB exam that was not previously diagnosed by means of other diagnostic modalities. RESULTS: A total of 233 scope procedures (84 transnasal bronchoscopies and 149 tracheoscopies) were reviewed, 232 of which were completed and one of which was incomplete due to severe subglottic stenosis. New, clinically relevant findings were seen in 57% of transnasal bronchoscopies (48 of 84) and 21% of tracheoscopies (32 of 149). All of these findings provided additional information directing workup or resulted in a change in patient management. CONCLUSION: Office-based evaluation of the tracheobronchial tree yields a high rate of new findings. In our study, office bronchoscopy had a 57% rate of new findings and was performed without complications. The utility of tracheoscopy was also apparent in its ability to quickly and safely examine the trachea, with a 21% rate of new findings. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:1376-1380, 2017. PMID- 27696421 TI - Response of saliva Na/K ratio to changing Na supply of lactating cows under tropical conditions. AB - BACKGROUND: Factorial determination of the sodium (Na) requirement of heat stressed lactating cows is hindered by accurate estimates of the Na losses through sweat. Direct studies, therefore, may be needed requiring information on the time course of healthy animals to become Na depleted and the subsequent rate of repletion. The rate of Na depletion and subsequent rate of Na repletion with two levels of dietary Na to lactating dairy cows housed under tropical conditions were investigated using the salivary Na/K. RESULTS: The 12 lactating cows (salivary Na/K ratio 14.6) rapidly developed clinical signs of Na deficiency, including pica, polyuria and polydipsia, reduced body weight and reduced milk yield when fed a low-Na ration (0.33 g kg-1 dry matter (DM)) for 3 weeks. Deficiency symptoms were associated with a rapid decrease in salivary Na/K ratio to <4.3 from 7 to 21 days. Subsequent repletion of the cows with NaCl to a ration concentration of 1.1 or 1.6 g Na kg-1 DM for 5 weeks did not restore salivary Na/K ratio to values of >6. CONCLUSION: A daily Na intake of heat-stressed lactating cows to a ration intake of 1.6 g Na kg-1 DM was insufficient to restore Na deficiency. One week was sufficient to deplete heat-stressed lactating cows of Na, allowing for rapid dose-response studies utilizing the salivary Na/K ratio as a parameter for Na status of cows under tropical conditions.

PMID- 27696423 TI - Microparticle surface layering through dry coating: impact of moisture content and process parameters on the properties of orally disintegrating tablets. AB - OBJECTIVES: The aim of this study was to investigate the influence of process parameters during dry coating on particle and dosage form properties upon varying the surface adsorbed moisture of microcrystalline cellulose (MCC), a model filler/binder for orally disintegrating tablets (ODTs). METHODS: The moisture content of MCC was optimised using the spray water method and analysed using thermogravimetric analysis. Microproperty/macroproperty assessment was investigated using atomic force microscopy, nano-indentation, scanning electron microscopy, tablet hardness and disintegration testing. KEY FINDINGS: The results showed that MCC demonstrated its best flowability at a moisture content of 11.2% w/w when compared to control, comprising of 3.9% w/w moisture. The use of the composite powder coating process (without air) resulted in up to 80% increase in tablet hardness, when compared to the control. The study also demonstrated that surface adsorbed moisture can be displaced upon addition of excipients during dry processing circumventing the need for particle drying before tabletting. CONCLUSIONS: It was concluded that MCC with a moisture content of 11% w/w provides a good balance between powder flowability and favourable ODT characteristics. PMID- 27696424 TI - Yeast and bacteria from ensiled high moisture maize grains as potential mitigation agents of fumonisin B1. AB - BACKGROUND: Fumonisin B1 (FB1 ) is a mycotoxin produced by several Fusarium species and is a very common contaminant of maize-based food and feed throughout the world. The selection and use of FB1 -degrading microorganisms appears as a promising alternative to cope with the problem of toxicity towards humans and livestock. High moisture maize grain silage, which is based on natural maize fermentation, could be an interesting reservoir of such microorganisms. RESULTS: Using an in vitro simulated silage model with FB1 naturally contaminated grains, we demonstrated a significant raw decrease in FB1 during ensiling process ascribed to biodegradation mechanisms. A panel of 98 bacteria and yeasts were isolated from this matrix and selected for their ability to use FB1 as the sole source of C and N. For nine of them, the ability to degrade FB1 in vitro was evidenced. Notably, two bacteria identified as Lactobacillus sp. were highlighted for their efficient FB1 -degrading capacity and production of hydrolysed FB1 as intermediate degradation metabolite. CONCLUSION: Fermentation of high moisture maize grain contaminated with FB1 leads to a significant reduction of the toxin and allows the isolation of FB1 -degrading microorganisms that could further be used as FB1 decontaminating agents.

AB - BACKGROUND: The hybrid grape cultivar 'Isabel' (Vitis labrusca * V. vinifera) is widely grown in the Black Sea region of Turkey and constitutes an important part of the diet of its inhabitants. Phenological and ampelographic studies of the grape have previously been performed, but there are no data concerning nutrient composition. Its nutrient content needs to be investigated to ascertain its potential economic and nutritional uses in the region. RESULTS: The concentrations (range, g kg-1 fresh weight) of major soluble sugars (fructose 2.08-79.70; glucose 3.71-66.74) increased and those of organic acids (tartaric acid 0.05-6.60; malic acid 2.38-9.92) decreased in the skin and pulp during ripening. The major fatty acid was linoleic acid in the skin (50.13), pulp (18.11) and seed (704), while the main minerals (dry weight) were potassium (2.70 19.70), followed by phosphorus (0.53-3.40) and calcium (0.42-5.90) in the parts. CONCLUSION: Berry maturation and ripening significantly influenced the concentrations of sugars and organic acids the most in the skin and pulp, but did not significantly affect the concentrations of fatty acids and minerals in the 'Isabel' grape. Our findings also suggest an optimal harvest time in terms of levels of the nutrients. (c) 2016 Society of Chemical Industry. PMID- 27696426 TI - Hybrid Minimal Core Streptavidin-Obelin as a Versatile Reporter for Bioluminescence-based Bioassay. AB - Ca2+ -regulated photoprotein obelin was genetically fused with a minimum-sized core streptavidin. Hybrid protein (SAV-OL) was produced by bacterial expression and applied as a specific bioluminescent probe in diverse solid-phase assays. The obtained results clearly demonstrate specific activity of each domain indicating its proper folding with favorable space orientation. SAV-OL has been shown to be a much more sensitive label than the chemical conjugate of a full-length streptavidin with obelin. PMID- 27696427 TI - Proteomic analysis of peel browning of 'Nanguo' pears after low-temperature storage. AB - BACKGROUND: Postharvest ripening of the 'Nanguo' pear (Pyrus ussuriensis Maxim.) can be impeded by low-temperature storage. However, pears after long-term refrigeration are prone to peel browning when returned to room temperature conditions. This study investigated the browning mechanism of 'Nanguo' pear stored at a low temperature by analysing the differentially expressed proteins between healthy fruit and fruit with peel browning. RESULTS: The results showed that 181 proteins underwent statistically significant changes. A categorisation of the disparately accumulated proteins was performed using gene ontology annotation. The results showed that the 'metabolic process', 'cellular process', 'catalytic activity', and 'binding' proteins were the most affected after low temperature storage. Further analysis revealed that the differentially expressed proteins, which are related to peel browning, are primarily involved in the phenylpropanoid pathway, linoleic acid pathways, fatty acid biosynthesis pathway, glutathione metabolism pathway, photosynthesis pathway, oxidative phosphorylation pathway, and glycolysis pathway. CONCLUSION: This study reveals that there are variations in key proteins in 'Nanguo' pear after low-temperature storage, and the identification of these proteins will be valuable in future functional genomics studies, as well as provide protein resources that can be used in the efforts to improve pear quality.

PMID- 27696428 TI - Transglutaminase-catalyzed amination of pea protein peptides using the biogenic amines histamine and tyramine. AB - BACKGROUND: Biogenic amines (BAs) are produced by the enzymatic decarboxylation of amino acids, and are well-known for their toxicity to humans. This study describes a new method using microbial transglutaminase (MTGase) to covalently link BAs such as histamine (HIS) and tyramine (TYR) to the glutamine residues of alcalase-hydrolyzed pea protein (PPH). RESULTS: The incubation of PPH and HIS and TYR in the presence of MTGase at 37 degrees C led to the formation of conjugates, as determined by liquid chromatography, after derivatization with dansyl chloride. Seventy-six % of HIS and 65% of TYR were covalently incorporated to PPH by MTGase. The incubation of PPH and TYR in the presence of MTGase exhibited a 52% DPPH radical scavenging activity at 10 mg mL-1 . Conjugation via MTGase improved the antioxidant status by reducing lipid peroxidation. CONCLUSION: This study emphasizes that the application of MTGase can effectively reduce histamine and tyramine content while simultaneously enhancing antioxidative capacity of PPH.

AB - Heat is a powerful tracer to quantify fluid exchange between surface water and groundwater. Temperature time series can be used to estimate pore water fluid flux, and techniques can be employed to extend these estimates to produce detailed plan-view flux maps. Key advantages of heat tracing include cost effective sensors and ease of data collection and interpretation, without the need for expensive and time-consuming laboratory analyses or induced tracers. While the collection of temperature data in saturated sediments is relatively straightforward, several factors influence the reliability of flux estimates that are based on time series analysis (diurnal signals) of recorded temperatures. Sensor resolution and deployment are particularly important in obtaining robust flux estimates in upwelling conditions. Also, processing temperature time series data involves a sequence of complex steps, including filtering temperature signals, selection of appropriate thermal parameters, and selection of the optimal analytical solution for modeling. This review provides a synthesis of heat tracing using diurnal temperature oscillations, including details on optimal sensor selection and deployment, data processing, model parameterization, and an overview of computing tools available. Recent advances in diurnal temperature methods also provide the opportunity to determine local saturated thermal diffusivity, which can improve the accuracy of fluid flux modeling and sensor spacing, which is related to streambed scour and deposition. These parameters can also be used to determine the reliability of flux estimates from the use of heat as a tracer. PMID- 27696431 TI - Cloning of the Blue Ghost (Phausis reticulata) Luciferase Reveals a Glowing Source of Green Light. AB - In the southern Appalachian area of the United States, the Phausis reticulata firefly, commonly known as the "Blue Ghost," performs a unique display of bioluminescence. Adult male organisms are observed darting rapidly along paths and riverbeds in dark forests producing long-lasting and mesmerizing bluish-white luminous streaks. Starting with eighteen adult male firefly lanterns, we used a reverse transcriptase and rapid amplification of cDNA ends (RACE) approach to clone the 1635 base pair open reading frame of the P. reticulata luc gene corresponding to a 545 residue protein. Expression of the recombinant luciferase protein in Escherichia coli and characterization studies revealed the true color of the light emission to be green (lambdamax = 552 nm), strongly suggesting that the field observations result from a Purkinje shift. While the P. reticulata luciferase amino acid sequence is 74.3% identical to the North American Photinus pyralis luciferase, we were surprised to find that it was 88.4% and 87.7% identical to luciferases from C. ruficollis and D. axillaris both native to mainland Japan. Phylogenetic analysis confirmed the close relationship of the three enzymes that is surprising given the great distance between their natural habitats and the inability of the Japanese fireflies to produce bright bioluminescence. PMID- 27696432 TI - The prognostic role of systemic inflammation in patients undergoing resection of colorectal liver metastases: C-reactive protein (CRP) is a strong negative prognostic biomarker. AB - BACKGROUND AND OBJECTIVES: Systemic inflammation has been associated with poor survival in several tumor types, but has been less extensively studied in resectable metastatic disease. The aim of the present study was to evaluate the prognostic role of CRP in colorectal cancer patients with liver metastases (CRLM) compared to conventional tumor- and patient-related clinicopathological features as well as other indicators of the systemic inflammatory response (SIR). METHODS: A multinational retrospective study of 492 CRLM patients undergoing potentially curative resection of liver metastases between 1999 and 2009. Clinicopathological findings and the SIR markers CRP, hypoalbuminemia, and their combined Glasgow Prognostic Score (GPS) were analyzed. RESULTS: Multivariate analysis showed that preoperative CRP >10 mg/L was a strong predictor of compromised survival (HR = 1.72, 95%CI 1.84-2.50, P < 0.01). Patients with CRP <=10 mg/L had a median survival of 4.27 years compared to only 47 days in patients with CRP >=30 mg/L (P < 0.01). Similarly, increased GPS was independently predictive of poor survival (HR 1.67, 95%CI 1.22-2.27, P < 0.01), but hypoalbuminemia alone did not have significant prognostic value. CONCLUSIONS: CRP alone is a strong prognostic factor, following curative resection of colorectal liver metastases and should be taken into consideration when selecting treatment strategies in CRLM patients.

PMID- 27696433 TI - How risk perception shapes collective action intentions in repressive contexts: A study of Egyptian activists during the 2013 post-coup uprising. AB - Social psychological research has overlooked collective action in repressive contexts, where activists face substantial personal risks. This paper examines the social psychological processes motivating activists to engage in collective action in risky contexts. We investigate the idea that perceived risks due to government sanctions can galvanize action through fuelling anger, shaping efficacy beliefs, and increasing identification with the movement. We also argue that anger, efficacy, and identification motivate action intentions directly and indirectly through reducing the personal importance activists attach to these risks. We tested our hypotheses within a sample of Egyptian activists (N = 146) from two protest movements who protested against Morsi's government and the military interventions, respectively, during the 2013 anticoup uprising. In line with our hypotheses, the perceived likelihood of risks was positively associated with anger and identity consolidation efficacy and positively predicted action intentions indirectly through these variables. Risk was also associated with increased political efficacy, but only among antimilitary protesters. Anger and political efficacy predicted action intentions directly and indirectly through reduced risk importance. Results also highlighted differential significance of emotional and instrumental motives for the two protest movements. We discuss directions for future research on the motivators of collective action in repressive contexts. PMID- 27696434 TI - Sonographic diagnosis of partial versus complete molar pregnancy: A reappraisal. AB - PURPOSE: To assess the prospective sonographic diagnosis of molar pregnancy and compare sonographic features of complete versus partial molar pregnancy. METHODS: This institutional review board--approved retrospective chart review conducted between 2001 and 2011 identified 70 women with a histopathologic diagnosis of molar pregnancy and with available sonograms. Clinical data, images, and reports were reviewed, and features enumerated by radiologists blinded to the final diagnosis. RESULTS: Mean age of patients was 30.5 +/- 7.0 (SD) years (range, 16 49 years) with a mean gravidity of 3.2 +/- 2.3 (SD) (range 1-11). Mean gestational age was 74.0 +/- 19.1 day (range 39-138) and serum beta-human chorionic gonadotropin was 131 +/- 156 mIU/ml (range 447-662,000). Pathologic results showed 48 partial and 22 complete molar pregnancies. Sonographically, partial moles more commonly showed a yolk sac (56.3% versus 0%, p < 0.0001), fetal pole (62.5% versus 4.6%, p < 0.0001), fine septa within the sac (25.0% versus 4.6%, p = 0.05), and normal (31.3% versus 0%, p = 0.002) or minimally cystic placenta (27.1% versus 4.6%, p = 0.49), while complete moles had larger gestational sacs (612 versus 44 mm, p = 0.005), were more often avascular on color Doppler imaging (45.5% versus 18.8%, p = 0.02), had more often abnormal tissue in the uterus (82.6% versus 20.8%, p < 0.0001) and placental masses (86.9% versus 16.7%, p < 0.0001), and were more often diagnosed prospectively (86.4% versus 41.7%, p = 0.0005). CONCLUSIONS: Complete molar pregnancy is associated with marked cystic changes and mass formation and is often diagnosed sonographically. Partial molar pregnancy often presents with minor cystic changes of the placenta and remains underdiagnosed sonographically. However, correct prospective diagnosis was made more frequently in this study than in older reports, perhaps due to improved spatial resolution of sonographic equipment.

AB - BACKGROUND: Peripheral stem cell collections can be challenging in the pediatric population and respective experience is limited. Since February 2015 our institution is utilizing the new Spectra Optia (Optia) apheresis device, which has replaced the former COBE Spectra (COBE) device. As a quality initiative we collected and compared collection efficiency (CE2) and other collection variables between the two devices. STUDY DESIGN AND METHODS: In this retrospective study we collected and compared clinical, laboratory, and technical collection data from stem cell collection procedures done with the Optia and COBE devices. The collected data included patient demographics, precollection peripheral CD34+ cell counts, total CD34+ cells collected, complete blood count, electrolytes before and after collection, side effects attributed to the collection, total blood volumes processed (TBVs), collection times, and calculated CE2 and collection ratios. RESULTS: Forty-one collection procedures performed on 29 pediatric patients with the Optia device were compared to 41 collections performed on 27 patients with the COBE device. The TBVs through the Optia device were significantly smaller than the COBE (3.9 +/- 0.2 * TBV vs. 5.5 +/- 0.1 * TBV, respectively; p < 0.001), requiring significantly less anticoagulant and providing similar amounts of stem cells while collection times were significantly shorter (mean, 238 +/- 9 min vs. 264 +/- 9 min, respectively; p < 0.05). Collections on the Optia caused significantly smaller reductions of plasma calcium and magnesium. No significant side effects attributed to the procedure were noted. CONCLUSION: Stem cell apheresis with the Optia device in children is safe and feasible with smaller blood volumes with shorter collection times. PMID- 27696437 TI - 'The deserving': Moral reasoning and ideological dilemmas in public responses to humanitarian communications. AB - This study investigates everyday moral reasoning in relation to donations and prosocial behaviour in a humanitarian context. The discursive analysis focuses on the principles of deservingness which members of the public use to decide who to help and under what conditions. The study discusses three repertoires of deservingness - 'seeing a difference', 'waiting in queues', and 'something for nothing' - to illustrate participants' dilemmatic reasoning and to examine how the position of 'being deserving' is negotiated in humanitarian crises. Discursive analyses of these dilemmatic repertoires of deservingness identify the cultural and ideological resources behind these constructions and show how humanitarianism intersects and clashes with other ideologies and value systems. The data suggest that a neoliberal ideology, which endorses self-gratification, materialistic and individualistic ethics, and cultural assimilation of helper and receiver play important roles in decisions about humanitarian helping. The study argues for the need for psychological research to engage more actively with the dilemmas involved in the moral reasoning related to humanitarianism and to contextualize decisions about giving and helping within the sociocultural and ideological landscape in which the helper operates. PMID- 27696438 TI - Are routine ultrasound examinations helpful in the detection of bleeding complications following laparoscopic inguinal hernia repair? AB - PURPOSE: Intraabdominal bleeding is a dreaded complication after laparoscopic transabdominal preperitoneal inguinal hernia repairs. Routine postoperative sonographic (US) examination and hemoglobin measurement have been suggested to identify bleeding after surgery. We retrospectively assessed the value of these tests. METHODS: A total of 995 consecutive patients admitted for laparoscopic inguinal hernia repair to a single teaching hospital were analyzed. US examinations were performed postoperatively on the operative day to identify intraabdominal bleeding. In addition, hemoglobin measurements were obtained on the first postoperative day. RESULTS: Postoperative US examinations were performed on 971 patients (97.6%). Of these, 945 were examined within 24 hours of surgery. Reoperation was necessary in 1.1% (11/995) of the patients because of a persistent seroma in five cases, intraabdominal or inguinal bleeding or hematomas in five cases, and a trocar hernia in one case. In none of the 11 patients requiring reoperation did US examination or hemoglobin measurement indicate acute bleeding or hematoma. CONCLUSIONS: Routine postoperative US examination and hemoglobin measurement within the first 24 hours of surgery are not suitable for identifying patients with intraabdominal bleeding who require a reoperation. Instead, US examination and hemoglobin measurement should be part of the patient workup when there is a clinical suspicion of a postoperative complication. (c) 2016 Wiley Periodicals, Inc.

AB - BACKGROUND AND OBJECTIVES: Both enchondroma and atypical cartilaginous tumors (ACT) are not considered malignant, so inactive and asymptomatic tumors might not need surgery. To the best of our knowledge, this is the first study that has been done to evaluate the natural course of conservative-treated enchondroma and ACT in the long bones. METHODS: For this retrospective study, we analyzed the results of patients in whom we refrained from surgery and only regularly performed radiological follow-up of the tumor. Minimal follow-up after initial diagnosis was 24 months. RESULTS: Forty-nine patients were included in this study. Eight out of forty-nine cases received surgical treatment during follow-up of the tumor. The reasons for this surgery were radiologic growth of the tumor in two cases, pain in one case, patient request in three cases, another indication for surgery in the same limb in two cases. CONCLUSION: In this small series of conservatively treated enchondroma and ACT, only 6% of the patients had a medical indication for surgery. This study shows that indication for surgery should be discussed more thoroughly. Based on our results, we would recommend annual radiologic follow-up for asymptomatic enchondroma or ACT in the long bones, irrespective of tumor size. J. Surg. Oncol. 2016;114:987-991.

AB - Raltegravir is a human immunodeficiency virus (HIV)-1 integrase strand transfer inhibitor currently marketed at a dose of 400 mg twice-daily (b.i.d.). Raltegravir 1200 mg once-daily (q.d.) (investigational q.d. formulation of 2 * 600 mg tablets; q.d. RAL) was found to be generally well tolerated and non inferior to the marketed 400 mg b.i.d. dose at 48 weeks in a phase 3 trial. Since raltegravir is eliminated mainly by metabolism via a uridine diphosphate glucuronosyltransferase (UGT) 1A1-mediated glucuronidation pathway, co administration of UGT1A1 inhibitors may increase the plasma levels of q.d. RAL. To assess this potential, the drug interaction of 1200 mg raltegravir using atazanavir, a known UGT1A1 inhibitor, was studied. An open-label, randomized, 2 period, fixed-sequence phase 1 study was performed in adult healthy male and female (non-childbearing potential) subjects >= 19 and <= 55 years of age, with a body mass index (BMI) >= 18.5 and <= 32.0 kg/m2 . Subjects (n = 14) received a single oral dose of 1200 mg raltegravir in period 1. After a washout period of at least 7 days, the subjects received oral doses of 400 mg atazanavir q.d. for 9 consecutive days, with a single oral dose of 1200 mg raltegravir co-administered on day 7 of period 2. Serial blood samples were collected for 72 h following raltegravir dosing and analysed using a validated bioanalytical method to quantify raltegravir plasma concentrations. Co-administration with atazanavir yielded GMRs (90% CIs) for raltegravir AUC0-infinity , Cmax and C24 of 1.67 (1.34, 2.10), 1.16 (1.01, 1.33) and 1.26 (1.08, 1.46), respectively. There was no effect of raltegravir on serum total bilirubin. In contrast, atazanavir increased the mean bilirubin by up to 200%, an effect that was preserved in the atazanavir/raltegravir treatment group. Administration of single q.d. RAL alone and co-administered with multiple oral doses of atazanavir were generally well tolerated in healthy subjects. The results show that atazanavir increased the PK exposure of raltegravir; therefore, co-administration of atazanavir with raltegravir q.d. is not recommended.

AB - OBJECTIVES/HYPOTHESIS: To study the prevalence and usefulness of audiometric notches in the diagnosis of noise-induced hearing loss (NIHL). STUDY DESIGN: Audiograms and data on noise exposure from 23,297 men and 26,477 women, aged 20 to 101 years, from the Nord-Trondelag Hearing Loss Study, 1996-1998. METHODS: The prevalence of four types of audiometric notches (Coles, Hoffman, Wilson) and 4 kHz notch were computed in relation to occupational noise exposure, age, sex, and report of recurrent ear infections. RESULTS: The prevalence of notches in the 3 to 6 kHz range (Wilson, Hoffman, and Coles) ranged from 50% to 60% in subjects without occupational noise exposure, and 60% to 70% in the most occupationally noise-exposed men. The differences were statistically significant only for bilateral notches. For 4 kHz notches, the prevalence varied from 25% in occupationally nonexposed to 35% in the most occupationally exposed men, and the differences were statistically significant for both bilateral and unilateral notches. For women, the prevalence of notches was lower than in men, especially for 4 kHz notches, and the differences between occupationally noise exposed and nonexposed were smaller. Recreational exposure to high music was not associated with notched audiograms. CONCLUSIONS: The detection of bilateral notches and unilateral 4 kHz notches is of some value in diagnosing NIHL, especially in men. LEVEL OF EVIDENCE: 4 Laryngoscope, 127:1442-1450, 2017. PMID- 27696441 TI - Cost effectiveness of adding nucleic acid testing to hepatitis B, hepatitis C, and human immunodeficiency virus screening of blood donations in Zimbabwe. AB - BACKGROUND: The aim of this study was to assess the cost effectiveness of introducing individual-donation nucleic acid testing (ID-NAT), in addition to serologic tests, compared with the exclusive use of serologic tests for the identification of hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) I and II among blood donors in Zimbabwe. STUDY DESIGN AND METHODS: The costs, health consequences, and cost effectiveness of adding ID-NAT to serologic tests, compared with serologic testing alone, were estimated from a health care perspective using a decision-analytic model. RESULTS: The introduction of ID-NAT in addition to serologic tests would lower the risk of HBV, HCV, and HIV transmission to 46.9, 0.3, and 2.7 per 100,000 donations, respectively. ID-NAT would prevent an estimated 25, 6, and 9 HBV, HCV, and HIV transfusion-transmitted infections per 100,000 donations, respectively. The introduction of this intervention would result in an estimated 212 quality adjusted life-years (QALYs) gained. The incremental cost-effectiveness ratio is estimated at US$17,774/QALY, a value far more than three times the gross national income per capita for Zimbabwe. CONCLUSION: Although the introduction of NAT could further improve the safety of the blood supply, current evidence suggests that it cannot be considered cost effective. Reducing the test costs for NAT through efficient donor recruitment, negotiating the price of reagents, and the efficient use of technology will improve cost effectiveness.

AB - Recycling cellulases by substrate adsorption is a promising strategy for reducing the enzyme cost of cellulosic ethanol production. However, beta-glucosidase has no carbohydrate-binding module (CBM). Thus, additional enzymes are required in each cycle to achieve a high ethanol yield. In this study, we report a new method of recycling cellulases without beta-glucosidase supplementation using lignocellulosic substrate, an engineered strain expressing beta-glucosidase and Tween 80. The cellulases and Tween 80 were added to an aqueous suspension of diluted sulfuric acid/ammonia-treated corncobs in a simultaneous saccharification and fermentation (SSF) process for ethanol production. Subsequently, the addition of fresh pretreated corncobs to the fermentation liquor and remaining solid residue provided substrates with absorbed cellulases for the next SSF cycle. This method provided excellent ethanol production in three successive SSF cycles without requiring the addition of new cellulases. For a 10% (w/v) solid loading, a cellulase dosage of 30 filter paper units (FPU)/g cellulose, 0.5% Tween 80, and 2 g/L of the engineered strain, approximately 90% of the initial ethanol concentration from the first SSF process was obtained in the next two SSF processes, with a total ethanol production of 306.27 g/kg corncobs and an enzyme productivity of 0.044 g/FPU. Tween 80 played an important role in enhancing cellulase recovery. This new enzyme recycling method is more efficient and practical than other reported methods. Biotechnol. Bioeng. 2017;114: 543-551.

AB - This study aims to assess serostatus and vaccination status of hepatitis A and B among staff at schools for the handicapped. We also wanted to investigate factors associated with serostatus, number of infections with hepatitis A/hepatitis B at work, and factors influencing being vaccinated or not. The cross-sectional study was carried out between August 2010 and August 2012 at 13 German schools for severely handicapped. Data were analyzed using blood samples, vaccination documents, and questionnaires. A total of 395 persons participated in our study (response: 59.7%), information on 367 could be used for analysis. Two respondents have been infected with HAV at work, 53.4% were anti-HAV seropositive. Vaccination against hepatitis A was influenced by information about infectious diseases before starting to work, level of education, and marital status. One person got infected with hepatitis B during work, 53.2% were anti-HBs seropositive. Vaccination against hepatitis B depended on perceived burden by nursing activities, and vaccination costs being paid by employer. Immunity to hepatitis A and B in our sample is insufficient and does not correspond to the infectious risks. Two persons got infected with hepatitis A and one person with hepatitis B during work at school, indicating an urgent need for preventive actions. J. Med. Virol. 89:825-833, 2017.

AB - BACKGROUND: There are no well-designed prospective studies evaluating transfusion practices in pediatric trauma. We sought to describe red blood cell (RBC) transfusion practices in trauma patients who were admitted to a pediatric intensive care unit (PICU). STUDY DESIGN AND METHODS: This study is a post-hoc analysis of a prospective, 6-month observational study in 30 PICUs. We studied a total of 580 patients aged less than 18 years who had been admitted to a PICU for more than 48 hours, including 95 who were trauma patients. RESULTS: Trauma patients more frequently received transfusion before PICU admission (p < 0.001), were older (p < 0.0001), and more frequently were mechanically ventilated (p = 0.05). In the PICU, trauma patients received more transfusions (55% vs. 37%; p < 0.001), although admission hemoglobin levels were similar in both groups (p = 0.86). The mean (+/- standard deviation) pretransfusion hemoglobin level in the PICU was 9.0 +/- 2.4 g/dL for trauma patients compared with 8.3 +/- 2.4 g/dL for nontrauma patients (p = 0.09). Among the trauma patients, transfusion was associated with younger age, higher Pediatric Logistic Organ Regression scores, mechanical ventilation, bleeding, and transfusion before PICU admission. Multivariate regression demonstrated that receiving an RBC transfusion before admission was strongly associated with receiving a blood transfusion in the PICU (p = 0.008). CONCLUSION: Trauma patients are at high risk for receiving an RBC transfusion both before and during their PICU stay, despite a similar transfusion threshold compared with nontrauma patients. Transfusion before PICU admission is a strong determinant, suggesting ongoing bleeding that will require re transfusion. Further studies are needed to evaluate whether a restrictive transfusion strategy can safely be considered in these patients. PMID- 27696447 TI - Symptomatic treatment of pollen-related allergic rhinoconjunctivitis in children: randomized controlled trial. AB - BACKGROUND: About 12% of children are affected by allergic rhinoconjunctivitis (AR). Although the main symptomatic treatments are intranasal corticosteroids (INCS) (daily or on demand) and oral antihistamines, it remains unclear which treatment provides the best relief of symptoms. Therefore, this study examines whether daily use of INCS is superior to on-demand use or to oral antihistamines on demand. METHODS: A single-blinded randomized controlled trial in children (aged 6-18 years) with pollen-related AR. Patients received either INCS daily (fluticasone propionate), INCS on demand (fluticasone propionate) or oral antihistamine on demand (levocetirizine) for 3 months during the grass pollen season. A daily online symptom diary on both nose and eye symptoms was completed. The primary outcome was the percentage of symptom-free days. RESULTS: A total of 150 children were randomized. The percentage symptom-free days was in favour of INCS on demand (30%) compared with INCS daily (22%), that is 8% difference (95% CI -5 to +21%; not significant). The antihistamine on-demand group had 15% symptom-free days, that is 7% difference compared to INCS daily (95% CI -6 to +19%;, not significant). Patients in the INCS on-demand group used on average 61% less fluticasone than patients in the INCS daily group during the study period (P < 0.0001). CONCLUSIONS: This trial with three parallel treatment groups shows that INCS daily was not superior to INCS on demand or to antihistamine on demand regarding the number of symptom-free days. An on-demand INCS strategy has the advantage of a lower overall corticosteroid exposure and less costs. PMID- 27696449 TI - The disappearance rate and risk assessment of thiacloprid residues in Asian pear using liquid chromatography confirmed with tandem mass spectrometry. AB - This study was undertaken to quantify the residue levels and propose the dissipation kinetics of thiacloprid formulated as suspension concentrate in field incurred Asian pears grown under two different open-field conditions. Samples were extracted with 20% distilled water in acetonitrile; partitioned with brine water and dichloromethane; and purified with a Florisil solid phase extraction cartridge. The analyte was identified with an LC ultraviolet detector, and field incurred samples were confirmed using LC-MS/MS. The calibration curve was linear over the range 0.05-5.0 mg/L with a satisfactory coefficient of determination (R2 = 0.9994). The limits of detection and limits of quantification (LOQ) were 0.003 and 0.01 mg/kg, respectively. The recovery rate fortified to blank samples at LOQ, 10* LOQ, and the maximum residue limit (MRL) were between 73.7 and 86.2% with relative standard deviation <=9.0%. The residual concentrations at both sites were considerably lower than the MRL (0.7 mg/kg) set by the Korean Ministry of Food Drug Safety, with biological half-lives of 5.0 and 7.4 days, for sites 1 and 2, respectively. From the pre-harvest residue limit curve, it was predicted that if the residues were <1.13 or 1.40 mg/kg 10 days before harvest, the residue level would be lower than the MRL during harvest. Risk assessment on day 0 showed an acceptable daily intake (%) of 13.0% and 11.0% for sites 1 and site 2, respectively, which indicates that the residual amounts are not hazardous to the Korean population.

PMID- 27696451 TI - Fibrosis is not just fibrosis - basement membrane modelling and collagen metabolism differs between hepatitis B- and C-induced injury. AB - BACKGROUND: While morphological patterns differ, the molecular phenotype of liver fibrosis is considered a stereotypical response to chronic liver injury. However, with different cellular triggers and networks regulating fibrosis, the molecular responses of the injured liver may not be identical. AIM: To investigate whether differences in extracellular matrix (ECM) composition of the liver during fibrogenesis in two seemingly similar types of viral hepatitis could be reflected by differences in ECM turnover. METHODS: Utilising a cross-sectional design, we measured specific ECM protein fragments in plasma from 197 chronic hepatitis B (CHB) patients and 403 chronic hepatitis C (CHC) patients matched for inflammation grade and fibrosis stage. Markers of matrix metalloprotease degraded type I, III, IV and VI collagen (C1M, C3M, C4M, C6M) and type III and IV collagen formation (Pro-C3, P4NP7S). RESULTS: P4NP7S, C3M, C4M and C6M were significantly elevated in CHB compared to CHC. In contrast, Pro-C3 was significantly elevated in CHC compared to CHB. Pro-C3, C3M and C4M were increased in parallel with inflammation and fibrosis in both cohorts. C6M and P4NP7S were associated with inflammation and fibrosis only in CHC. Basement membrane collagen fragments P4NP7S and C4M were significantly higher in matched activity and fibrosis cohorts within CHB vs CHC. CONCLUSION: The main parameters to determine extracellular matrix biomarker levels are inflammation, fibrosis, and type of viral insult. Compared to CHC, CHB appears to induce a higher basement membrane turnover. This suggests that there are aetiology-dependent molecular signatures in liver fibrosis that could have pathogenic and diagnostic implications. PMID- 27696448 TI - Effective fluorescence-guided surgery of liver metastasis using a fluorescent anti-CEA antibody. AB - BACKGROUND AND OBJECTIVES: Delineation of adequate tumor margins is critical in oncologic surgery, particularly in resection of metastatic lesions. Surgeons are limited in visualization with bright-light surgery, but fluorescence-guided surgery (FGS) has been efficacious in helping the surgeon achieve negative margins. METHODS: The present study uses FGS in a mouse model that has undergone surgical orthotopic implantation (SOI) of colorectal liver metastasis tagged with green fluorescent protein (GFP). An anti-CEA antibody conjugated to DyLight 650 was used to highlight the tumor. RESULTS: The fluorescent antibody clearly demarcated the lesion at deeper tissue depth compared to GFP. Fluorescence of the anti-CEA-DyLight650 showed maximal tumor-to-liver contrast at 72 hr. Fifteen mice underwent bright-light surgery (BLS) versus FGS with GFP versus FGS with anti-CEA DyLight650. Mice that underwent FGS had a significantly smaller area of residual tumor (P < 0.001) and significantly longer overall survival (P < 0.001) and disease-free survival (P < 0.001). Within the two FGS groups, mice undergoing surgery with anti-CEA-DyLight650 improved survival compared to only GFP labeling. CONCLUSIONS: In the present report, we demonstrate that an anti-CEA antibody conjugated to a DyLight 650 nm dye clearly labeled colon cancer liver metastases, thereby enabling successful FGS. J.

PMID- 27696452 TI - European symposium on the awareness of allergy: report of the promotional campaign in the European Parliament (26-28 April 2016). AB - From 26 to 28 of April 2016, an allergy awareness campaign was organized by the European Academy of Allergy and Clinical Immunology and the European Federation of Allergy and Airway Diseases Patients Associations in the European Parliament in Brussels, with support of the European Parliament's Interest group on Allergy and Asthma and was co-hosted by the Members of the European Parliament David Borrelli, Sirpa Pietikainen and Nessa Childers. Skin prick tests (SPTs) were performed to gain attention for the increasing prevalence of allergic airway diseases in Europe. Since more than 30% of the total European population suffers from airway allergies and asthma, reaching a higher level of awareness and elaboration of an active prevention plan is mandatory. Of the 406 individuals undergoing SPT in the European Parliament, 211 participants (52%) reported to have suffered from an allergy in the past, with allergic symptoms being present in the nose and eyes (40% and 36%, respectively), the skin (27%), lower airways (14%) and the gut (8%). Of the 381 SPT with reliable results, cutaneous hypersensitivity was found in 201 (53%) participants. Of those with positive SPT (n = 201), 70 participants (35%) were monosensitized while 131 participants (65%) were polysensitized. The positive skin reactions were found mostly for grass pollen (n = 108), followed by Dermatophagoides pteronyssinus (n = 105), Dermatophagoides farina (n = 96) and birch pollen (n = 85). Of note, 54 individuals (14% of the total tested population) without reported allergy or allergic symptoms showed a positive SPT without clinical relevance. This report summarizes the main idea and goals of the symposium: chronic airway diseases are a major and growing health problem in Europe. Therefore, a joint preventive action plan needs to be developed for a better health status of European citizens. PMID- 27696453 TI - Development and evaluation of a hydrophilic interaction liquid chromatography MS/MS method to quantify 19 nucleobases and nucleosides in rat plasma. AB - As essential endogenous compounds, nucleobases and nucleosides fulfill various functions in living organisms. This study presents the development and validation of a new hydrophilic interaction liquid chromatography tandem mass spectrometry method for simultaneous quantification of 19 nucleobases and nucleosides in rat plasma. For the sample preparation, 15 kinds of protein precipitants were evaluated according to the chromatographic profile and ion response of analytes. The optimization of chromatographic separation was respectively performed using reversed-phase liquid chromatography and hydrophilic interaction liquid chromatography mode; each separation mode included two test columns with different stationary phases. The chromatographic profile and parameters such as half-width (W1/2 ), capacity factor (K') and tailing factor (ft ) were used to evaluate the separation efficiencies. Furthermore, the adopted composition of two mobile phase systems and the concentrations of the additives in the optimum buffer system were also investigated. The developed method was fully validated and successfully applied quantitatively to determine 19 nucleobases and nucleosides in plasma from normal and diabetic nephropathy (DN) rats. Significant differences between normal and DN rats were found in plasma levels of cytosine, xanthine, thymidine, adenosine, guanosine, inosine and 8-hydroxy-2' deoxyguanosine. This information may provide a useful reference for the discovery of potential biomarkers of DN. PMID- 27696454 TI - Transfusion of 35-day stored red blood cells does not result in increase of plasma non-transferrin bound iron in human endotoxemia. AB - BACKGROUND: Transfusion of a single unit of stored red blood cells (RBCs) has been hypothesized to induce supra-physiological levels of non-transferrin bound iron (NTBI), which may enhance inflammation and act as a nutrient for bacteria. We investigated the relation between RBC storage time and iron levels in a clinically relevant "two-hit" human transfusion model. STUDY DESIGN AND METHODS: Eighteen healthy male volunteers (ages 18-35 years) were infused with 2 ng lipopolysaccharide (LPS)/kg to induce systemic inflammatory response syndrome. Two hours later, each participant received either 1 unit of 2-day stored (2D) autologous RBCs, 35-day stored (35D) autologous RBCs, or an equal volume of saline. Every 2 hours up to 8 hours after LPS infusion, hemoglobin, hemolysis parameters, and iron parameters, including NTBI, were measured. RESULTS: Transfusion of both 2D and 35D RBCs caused increases in hemoglobin, plasma iron, and transferrin saturation; whereas levels remained stable in the saline group. Transfusion of 35D RBCs did not result in hemolysis nor did it lead to increased levels of NTBI compared with 2D RBCs or saline. LPS induced increases in ferritin, haptoglobin, bilirubin, and lactate dehydrogenase that were similar in all three groups. CONCLUSION: We conclude that 35D autologous RBCs do not cause hemolysis or increased levels of NTBI during human endotoxemia. PMID- 27696455 TI - A new method for the assessment of the surface topography of NiTi rotary instruments. AB - AIM: To describe a new method for the assessment of nanoscale alterations in the surface topography of nickel-titanium endodontic instruments using a high resolution optical method and to verify the accuracy of the technique. METHODOLOGY: Noncontact three-dimensional optical profilometry was used to evaluate defects on a size 25, .08 taper reciprocating instrument (WaveOne(r) ), which was subjected to a cyclic fatigue test in a simulated root canal in a clear resin block. For the investigation, an original procedure was established for the analysis of similar areas located 3 mm from the tip of the instrument before and after canal preparation to enable the repeatability and reproducibility of the measurements with precision. All observations and analysis were taken in areas measuring 210 * 210 MUm provided by the software of the equipment. RESULTS: The three-dimensional high-resolution image analysis showed clear alterations in the surface topography of the examined cutting blade and flute of the instrument, before and after use, with the presence of surface irregularities such as deformations, debris, grooves, cracks, steps and microcavities. CONCLUSIONS: Optical profilometry provided accurate qualitative nanoscale evaluation of similar surfaces before and after the fatigue test. The stability and repeatability of the technique enables a more comprehensive understanding of the effects of wear on the surface of endodontic instruments. PMID- 27696456 TI - Systematic review with meta-analysis: endoscopic retrograde cholangiopancreatography-based modalities for the diagnosis of cholangiocarcinoma in primary sclerosing cholangitis. AB - BACKGROUND: The accuracy of current endoscopic modalities for diagnosing cholangiocarcinoma in primary sclerosing cholangitis (PSC) is suboptimal. AIM: To evaluate the comparative effectiveness of endoscopic retrograde cholangiopancreatography (ERCP)-based modalities, independently or in combination, for the diagnosis of cholangiocarcinoma in patients with PSC-induced biliary strictures. METHODS: Searches of PubMed, EMBASE, Web of Science and the Cochrane Library databases were performed through December 2015. Measured outcomes included sensitivity and specificity of all diagnostic modalities independently or in combination. A bivariate model was used to compute the pooled sensitivity and specificity, and to plot the summary receiver operating characteristics curve with summary point and corresponding 95% confidence interval (95% CI). A logistic regression model was used to impute the incremental performance of combining two diagnostic tests. RESULTS: Twenty-one studies met inclusion criteria: 13 on bile duct brushing for cytology, 7 on fluorescence in situ hybridisation (FISH), 2 on probe-based confocal laser endomicroscopy, and 4 on single-operator cholangioscopy with targeted biopsies. Single-operator cholangioscopy with targeted biopsies was the most accurate diagnostic modality at 96% (95% CI, 94-97%). The pooled sensitivity and specificity of single operator cholangioscopy for diagnosis of cholangiocarcinoma in patients with PSC was 65% (95% CI, 35-87%) and 97% (95% CI, 87-99%), respectively. The pooled diagnostic odds ratio to detect cholangiocarcinoma was 59 (95% CI, 10-341). CONCLUSIONS: Single-operator cholangioscopy with targeted biopsies appears to be the most accurate ERCP-based modality for diagnosing cholangiocarcinoma in primary sclerosing cholangitis. However, future large, well-designed comparative diagnostic studies are warranted to validate these findings. PMID- 27696458 TI - Iron acquisition and siderophore production in the fish pathogen Renibacterium salmoninarum. AB - Renibacterium salmoninarum is the causative agent of bacterial kidney disease, which significantly affects salmonid farming worldwide. Despite this impact, there is scarce data on its iron uptake ability, a factor of pathogenesis. This study investigated the iron acquisition mechanisms of R. salmoninarum and its capacity to uptake iron from different sources. Thirty-two Chilean isolates and the DSM20767T type strain grew in the presence of 2,2'-Dipyridyl at varying concentrations (250-330 MUm), and all isolates positively reacted on chrome azurol S agar. Subsequently, inocula of four Chilean isolates and the type strain were prepared with or without 200 MUm of 2,2'-Dipyridyl for uptake assays. Assay results revealed differences between the isolates in terms of iron acquisition. While a prior iron-limited environment was, for most isolates, not required to activate the uptake of iron (II) sulphate, ammonium iron (III) citrate or iron (III) chloride at higher concentrations (100 MUm), it did facilitate growth at lower iron concentrations (10 MUm and 1 MUm). An exception was the H-2 isolate, which only grew with 100 MUm of iron sulphide. In turn, 100 MUm of haemin was toxic when isolates were grown in normal KDM-2. In silico R. salmoninarumATCC 33209T genome analysis detected various genes coding iron uptake-related proteins. This is the first study indicating two iron acquisition systems in R. salmoninarum: one involving siderophores and another involving haem group utilization. These data represent a first step towards fully elucidating this virulence factor in the pathogenic R. salmoninarum. PMID- 27696457 TI - Glyoxalase 2 Is Involved in Human Prostate Cancer Progression as Part of a Mechanism Driven By PTEN/PI3K/AKT/mTOR Signaling With Involvement of PKM2 and ERalpha. AB - BACKGROUND: Glyoxalase 2 (Glo2), together with glyoxalase 1 (Glo1), forms the main scavenging system of methylglyoxal, a potent pro-apoptotic agent mainly generated by glycolysis. An increased rate of glycolysis is a well known signature of cancer cells. As a survival strategy, Glo1 is overexpressed in many human malignant cells, including prostate cancer (PCa), where it plays a crucial role in progression. No information is available on the role of Glo2 in the same ambit. PCa is the most common malignancy affecting men in the western world. Progression to a lethal hormone-refractory PCa represents the major concern in this pathology. Therefore, a deeper understanding of the molecular mechanisms underlying PCa invasiveness and metastasis is urgently needed in order to develop novel therapeutic targets for this incurable state of the malignancy. METHODS: Glo2 and Glo1 expression was examined in clinical samples of PCa by immunohistochemistry and in different PCa cell models by western blotting and quantitative real-time polymerase chain reaction. Gene silencing/overexpression and scavenging/inhibitory agents were used for functional analyses. RESULTS: We demonstrated that Glo2, together with Glo1, represents a novel mechanism in PCa progression as part of a pathway driven by PTEN/PI3K/AKT/mTOR signaling with involvement of PKM2 and ERalpha. Importantly, Glo1/Glo2 silencing did not alter the behavior of benign cells. CONCLUSIONS: Targeting glyoxalases metabolic pathway may represent a strategy to selectively inhibit advanced PCa.

AB - Using the quantum theory of atoms in molecules a near complete combined directed spanning quantum topology phase diagram (QTPD) was constructed from the nine (H2 O)5 reaction-pathways and five unique Poincare-Hopf solutions that were found after an extensive search of the MP2 potential energy surface. Two new energy minima that were predicted from earlier work are found and include the first (H2 O)5 conformer with a 3-DQT quantum topology. The stress tensor Poincare-Hopf relation indicated a preference for 2-DQT (H2 O)5 topologies as well as the presence of coupling between shared-shell O?H BCPs to the hydrogen-bond BCPs that share an H NCP. The complexity of the near complete combined QTPD was explained in terms of the O...O bonding interactions that were found in six of the nine (H2 O)5 reaction-pathways and for all points of the combined QTPD. The stabilizing role of the O...O bonding interactions from the values of the total local energy density was explored. (c) 2016 Wiley Periodicals, Inc.

In order to accurately describe the epidemiology of this virus, the genetic diversity of the complete G gene and the clinical manifestations observed were jointly analyzed. Out of 3,011 respiratory specimens taken from 2,308 children, 640 were positive to RSV (21.3%) and 405 were RSV-A (63.2%). Complete G gene sequences of 166 randomly selected RSV-A virus identified NA1 and ON1 genotypes. In 2011-2012, ON1 emerged sporadically and become dominant in 2012-2013 with 38 cases (70%). In 2014-2015, all the 44 sequences contained the 72-nt duplication (100%). Clinical diagnosis of children with ON1 genotype were bronchiolitis in 55 (62.5%), recurrent wheezing or asthma exacerbations in 22 (25%), laryngotracheobronchitis in 3 (3.4%), and upper respiratory tract infections in eight. Results showed replacement and substitution of circulating NA1 genotype with the new ON1 genotype. Nevertheless, at this stage, none of the RSV-A genotypes identified have resulted in significant clinical differences. The amino acid composition of the complete G gene ON1 sequences demonstrated an accumulation of single changes not related with different clinical presentation. J. Med. Virol. 89:767-774, 2017.

AB - OBJECTIVE: To determine common methods for intra-articular injections and variables associated with the risk of septic arthritis following intra-articular injection in the horse. STUDY DESIGN: Cross-sectional survey. SAMPLE POPULATION: Equine veterinarians. METHODS: A link to an online survey was distributed to equine practitioners in 2014. Responses for descriptive data were tabulated. Data on infection rates obtained from medical records were analyzed. Variables associated with the risk of septic arthritis were determined using chi2 or Fisher's exact tests and logistic regression. RESULTS: Common current methods for intra-articular injections were determined from 241 surveys. Sixty-four of 241 surveys (26.6%) contained data with numbers of joints injected and number of infections obtained from review of medical records. Eight different injection methods were used by more than 2/3 of responding veterinarians. A total of 67 out of 319,760 injected joints reported became septic following injection, giving an incidence of 2.10 septic joints per 10,000 intra-articular injections. Based on multivariate analysis, infection rates were significantly lower when veterinarians prepared their own injection sites (OR=0.10) and had <20 years of practice experience (OR=0.025), whereas infection rates were significantly higher when hair was removed at the injection site (OR=19.70). CONCLUSION: There is a low incidence of septic arthritis following intra-articular injection and a large number of injection methods reported by responding veterinarians. The low reported incidence of infection may be related to the large number of practitioners frequently using common methods. PMID- 27696462 TI - An early innate response underlies severe influenza-induced exacerbations of asthma in a novel steroid-insensitive and anti-IL-5-responsive mouse model. AB - BACKGROUND: Acute worsening of asthma symptoms (exacerbation) is predominantly triggered by respiratory viruses, with influenza causing the most severe exacerbations. The lack of an adequate animal model hampers mechanistic insight and the development of new therapeutics. AIM: We developed and characterized a robust, consistent, and reproducible mouse model of severe exacerbation of chronic allergic asthma. METHODS: Chronic allergic airway inflammation was induced following a house dust mite (HDM) sensitization protocol. HDM-sensitized mice and controls were infected with influenza virus A/X31 H3N2 and either or not treated with inhaled fluticasone propionate (FP), systemic corticosteroids (Pred), or anti-IL-5. Mice were killed at different time points after infection: Cellular accumulation and cytokines levels in the airways, PenH as a measure of airway hyper-responsiveness (AHR), and lung histology and viral replication were assessed. RESULTS: Infection with low-dose A/X31 H3N2 led to prolonged deterioration of lung function, aggravated mucus production, peri-vascular, peri bronchial, and allergic inflammation that was unresponsive to inhaled corticosteroids, but responsive to systemic corticosteroids. The exacerbation was preceded at 14 h after virus exposure by a marked innate, but no Th2 and Th1 response subsequently followed by enhanced numbers of eosinophils, neutrophils, dendritic, and T cells into the lung lumen, parenchyma, and draining lymph nodes in HDM-sensitized mice. Anti-IL-5 treatment attenuated eosinophils and prevented the X31-induced exacerbation. CONCLUSIONS: Together, these findings indicate that an early innate response that involves eosinophils underlies the exacerbation. This model recapitulates all major features of severe asthma exacerbations and can serve to discern driving mechanisms and promote the development of novel therapeutics.

AB - Although the analysis of length polymorphism at STR loci has become a method of choice for grape cultivar identification, the standardization of methods for this purpose lags behind that of methods for DNA profiling in human and animal forensic genetics. The aim of this study was thus to design and validate a grapevine STR protocol with a practically useful level of multiplexing. Using free bioinformatics tools, published primer sequences, and nucleotide databases, we constructed and optimized a primer set for the simultaneous analysis of six STR loci (VVIi51, scu08vv, scu05vv, VVMD17, VrZAG47, and VrZAG83) by multiplex PCR and CE with laser-induced fluorescence, and tested it on 90 grape cultivars. The new protocol requires subnanogram quantities of the DNA template and enables automated, high-throughput genetic analysis with reasonable discriminatory power. As such, it represents a step toward further standardization of grape DNA profiling. PMID- 27696464 TI - Hazards in chromatographic bioanalysis method development and applications. AB - Bioanalytical methods are employed for the quantitative determination of drugs and their metabolites in biological matrices, in all stages of the drug development process. However, because of the highly complex nature of these matrices there is a wide range of potential biological, chemical and physical hazards that can influence the quality of the data produced by these methods. The present review focuses on the evaluation of the most important and frequent errors that may be encountered during bioanalytical method development/validation and analysis of clinical or preclinical samples mainly using chromatography. Additionally, the most practical ways for avoiding and managing these hazards during routine bioanalysis are presented. PMID- 27696466 TI - Virucide properties of cold atmospheric plasma for future clinical applications. AB - Cold atmospheric plasma (CAP) has been repeatedly identified to bear powerful microbicidal efficacy on bacteria including multidrug resistant organisms and fungi on non-living surfaces, in biofilms as well as on contaminated and infected tissues. CAP furthermore was found to stimulate wound healing in chronic wounds and exerted anti-neoplastic effects on numerous tumor entities. Thus, CAP represents a promising medical tool for many clinical and therapeutic issues. Studies about CAP effects on virus particles recently were in arrears, but to date increasingly move into the focus of interest. Apparently, CAP treatment is followed by a promising virus inactivation and contributes to tissue regeneration. Here we review the current state of science concerning the so far investigated CAP effects on different virus species and virus-associated disorders. J. Med. Virol. 89:952-959, 2017.

AB - Human papillomavirus infection is a major health problem and caused substantial benign and malignancy diseases among female and male worldwide. We aim to investigate the epidemiology of high-risk human papillomavirus (HR-HPV) and related diseases in Suzhou population. As well as evaluating the potential benefit of a nine-valent HPV vaccine (regardless of HPV-6 and -11) in Suzhou. A total of 40,108 people aged 13-89 years were retrospectively examined by database retrieval from 2010 to 2015. Thirteen genotypes (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 66) of HR-HPV were detected using TellgenplexTM xMAPTM HPV DNA Test assay. The overall prevalence of HR-HPV was 21.1%, the female and male account for 96.4% and 3.6%, respectively. The infection rate among male (25.6%, 367/1,432) was significantly higher than that among female (20.9%, 8,100/38,676), X2 = 17.341 (P < 0.001), with OR = 1.293, 95% CI (1.146-1.460). The five most frequent HR-HPV genotypes were HPV-16 (5.12%), -52 (5.07%), -58 (3.02%), -39 (2.00%), and -18 (1.74%). HR-HPV infection rate was peak in person aged <20 years, and second higher in person aged 51-60 years. Infection modes as HPV-16, 18, -31, -33, -45, -52, -58 alone or mixed accounted for 63.2%. The top three prevalent diseases in HR-HPV infected women were cervicitis, vaginitis, and cervical lesions, and in men were verruca, urethritis, and balanitis, respectively. This is the first study to demonstrate HPV infection status in Suzhou population. Both women and men had a large burden of HPV infection. The nine-valent HPV prophylactic vaccines may potentially prevent 63.2% HR-HPV infection in Suzhou. J. Med. Virol. 89:895-901, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27696467 TI - Determination of ethyl glucuronide and fatty acid ethyl esters in hair samples. AB - Hair testing for alcohol biomarkers is an important tool for monitoring alcohol consumption. We propose two methods for assessing alcohol exposure through combined analysis of ethyl glucuronide (EtG) and fatty acid ethyl esters (FAEEs) species (ethyl myristate, palmitate, stearate and oleate) in hair (30 mg). EtG was analysed by liquid chromatography-tandem mass spectrometry, while FAEEs were analysed by gas chromatography-tandem mass spectrometry using electron impact ionization. Both methods were validated according to internationally accepted guidelines. Linearity was proven between 3 and 500 pg/mg for EtG and 30-5000 pg/mg for FAEEs, and the limits of quantification were 3 pg/mg for EtG and 30 pg/mg for each of the four FAEEs. Precision and accuracy were considered adequate, processed EtG samples were found to be stable for up to 96 h left in the injector and processed FAEEs samples for up to 24 h. Matrix effects were not significant. Both methods were applied to the analysis of 15 authentic samples, using the cut-off values proposed by the Society of Hair Testing for interpretation. The results agreed well with the self-reported alcohol consumption in most cases, and demonstrated the suitability of the methods to be applied in routine analysis of alcohol biomarkers, allowing monitoring consumption using low sample amounts. PMID- 27696468 TI - Validity of Exercise Measures in Adults with Anorexia Nervosa: The EDE, Compulsive Exercise Test and Other Self-Report Scales. AB - OBJECTIVE: Compulsive exercise is a prominent feature for the majority of patients with Anorexia Nervosa (AN), but there is a dearth of research evaluating assessment instruments. This study assessed the concurrent validity of the exercise items of the Eating Disorder Examination (EDE) and Eating Disorder Examination-Questionnaire (EDE-Q), with the Compulsive Exercise Test (CET) and other self-report exercise measures in patients with AN. We also aimed to perform validation of the CET in an adult clinical sample. METHODS: The sample consisted of 78 adults with AN, recruited for the randomized controlled trial "Taking a LEAP forward in the treatment of anorexia nervosa." At baseline, participants completed the EDE, EDE-Q, CET, Reasons for Exercise Inventory (REI), Commitment to Exercise Scale (CES) and Exercise Beliefs Questionnaire (EBQ). Correlational and regression analyses were performed. RESULTS: EDE exercise days and exercise time per day were positively correlated with each other and with all CET subscales (except Lack of exercise enjoyment), CES mean, EBQ total and REI total. Exercise time per day was associated with a higher EDE global score. The CET demonstrated good concurrent validity with the CES, the REI and the EBQ. Of the self-reports, the CET explained the greatest variance in eating disorder psychopathology and demonstrated good to excellent reliability in this sample. DISCUSSION: The EDE and EDE-Q demonstrated good concurrent validity with the CET. Further research is required to evaluate the CET's factor structure in a large clinical sample. However, the CET has demonstrated strong clinical utility in adult patients with AN. (c) 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:533-541). PMID- 27696469 TI - Three dimensional ultrasonography for advanced neurosonography (Neurosofe-3d). Analysis of acquisition-related factors influencing the quality of the brain volumes. AB - OBJECTIVE: To evaluate the acquisition-related factors influencing the quality of the brain volumes for further study of advanced neurosonography. METHODS: This was a prospective multicentre study. Five centres were asked to include five cases each, acquiring two volumes per case, at different gestational ages. Ten operators performed an advanced neurosonography per case. The potential influence of the following factors on the number of evaluable structures was assessed: vaginal/ abdominal acquisition, position of the head, gestational age, subjective quality of the volume and the acquiring operator itself. RESULTS: Four hundred and thirty-two evaluations were included in the study. A total of 80% of the structures were evaluated satisfactorily in the axial plane, 67.1% and 55.1% in the coronal and sagittal plane, respectively. Sagittal volumes acquired transvaginally had a better quality than those acquired transabdominally. Gestational age affected the quality of axial and sagittal volumes (p < 0.001), and the best quality was obtained between 20 and 27 weeks. In axial and sagittal volumes, the head position influenced the percentage of structures visualized (p < 0.001, p < 0.001). CONCLUSIONS: Factors affecting the quality of the volume for advanced neurosonography are gestational age, fetal head position, transvaginal acquisition in sagittal volumes, the acquiring operator and the subjective quality of the volume.

AB - Lysine acetylation is an important post-translational modification (PTM). Since the development of MS-based proteomics technology, important roles of lysine acetylation beyond histones have focused on chromatin remodeling during the cell cycle and regulation of nuclear transport, metabolism, and translation. Zebrafish (Danio rerio) is a widely used vertebrate model in genetics and biologic studies. Although studies in several mammalian species have been performed, the mechanism of lysine acetylation in D. rerio embryos is incompletely understood. Here, we investigated the global acetylome in D. rerio embryos by using an MS-based proteomics approach. We identified 351 acetylated peptides and 377 nonredundant acetylation sites on 189 lysine-acetylated proteins in 5-day postfertilization (hpf) embryos of D. rerio. Among lysine-acetylated peptides, 40.2% indicated three motifs: (ac)KxxxK, (ac)KxxxxK, and Lx(ac)K. Of 190 acetylated proteins, 81 (42.6%) were mainly distributed in the cytoplasm. Gene ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses showed that lysine acetylation in D. rerio was enriched in metabolic pathways. Additionally, 17 of 30 acetylated ribosomal proteins were evolutionarily conserved between zebrafish and humans. Our results indicate that acetyllysine might have regulatory effects on ribosomal proteins involved in protein biosynthesis. PMID- 27696470 TI - Disposition of intravenously or orally administered silver nanoparticles in pregnant rats and the effect on the biochemical profile in urine. AB - Few investigations have been conducted on the disposition and fate of silver nanoparticles (AgNP) in pregnancy. The distribution of a single dose of polyvinylpyrrolidone (PVP)-stabilized AgNP was investigated in pregnant rats. Two sizes of AgNP, 20 and 110 nm, and silver acetate (AgAc) were used to investigate the role of AgNP diameter and particle dissolution in tissue distribution, internal dose and persistence. Dams were administered AgNP or AgAc intravenously (i.v.) (1 mg kg-1 ) or by gavage (p.o.) (10 mg kg-1 ), or vehicle alone, on gestation day 18 and euthanized at 24 or 48 h post-exposure. The silver concentration in tissues was measured using inductively-coupled plasma mass spectrometry. The distribution of silver in dams was influenced by route of administration and AgNP size. The highest concentration of silver (MUg Ag g-1 tissue) at 48 h was found in the spleen for i.v. administered AgNP, and in the lungs for AgAc. At 48 h after p.o. administration of AgNP, the highest concentration was measured in the cecum and large intestine, and for AgAc in the placenta. Silver was detected in placenta and fetuses for all groups. Markers of cardiovascular injury, oxidative stress marker, cytokines and chemokines were not significantly elevated in exposed dams compared to vehicle-dosed control. NMR metabolomics analysis of urine indicated that AgNP and AgAc exposure impact the carbohydrate, and amino acid metabolism. This study demonstrates that silver crosses the placenta and is transferred to the fetus regardless of the form of silver. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - Serum levels of Prostate-Specific Antigen (PSA) are not fully specific for prostate cancer (PCa) diagnosis and several efforts are focused on searching to improve PCa markers through the study of PSA subforms that could be cancer associated. We have previously reported by 2DE a decrease in the sialic acid content of PSA from PCa compared to benign prostatic hyperplasia patients based on the different proportion of the PSA spots. However, faster and more quantitative techniques, easier to automate than 2DE, are desirable. In this study, we examined the potential of CE for resolving PSA subforms in different samples and compared the results with those obtained by 2DE. We first fractionated by OFFGEL the subforms of PSA from seminal plasma according to their pIs and analyzed each separated fraction by 2DE and CE. We also analyzed PSA and high pI PSA, both from seminal plasma, and PSA from urine of a PCa patient. These samples with different PSA spots proportions by 2DE, due to different posttranslational modifications, also presented different CE profiles. This study shows that CE is a useful and complementary technique to 2DE for analyzing samples with different PSA subforms, which is of high clinical interest. PMID- 27696473 TI - Transfusion-related immunomodulation: review of the literature and implications for pediatric critical illness. AB - Transfusion-related immunomodulation (TRIM) in the intensive care unit (ICU) is difficult to define and likely represents a complicated set of physiologic responses to transfusion, including both proinflammatory and immunosuppressive effects. Similarly, the immunologic response to critical illness in both adults and children is highly complex and is characterized by both acute inflammation and acquired immune suppression. How transfusion may contribute to or perpetuate these phenotypes in the ICU is poorly understood, despite the fact that transfusion is common in critically ill patients. Both hyperinflammation and severe immune suppression are associated with poor outcomes from critical illness, underscoring the need to understand potential immunologic consequences of blood product transfusion. In this review we outline the dynamic immunologic response to critical illness, provide clinical evidence in support of immunomodulatory effects of blood product transfusion, review preclinical and translational studies to date of TRIM, and provide insight into future research directions. PMID- 27696474 TI - Melatonin exacerbates acute experimental autoimmune encephalomyelitis by enhancing the serum levels of lactate: A potential biomarker of multiple sclerosis progression. AB - Melatonin has a beneficial role in adult rat models of multiple sclerosis (MS). In this study, melatonin treatment (10 mg/kg/d) was investigated in young age (5 6 weeks old) Lewis rat model of acute experimental autoimmune encephalomyelitis (EAE) followed by assessing serum levels of lactate and melatonin. Results showed that clinical outcomes were exacerbated in melatonin- (neurological score = 6) vs PBS-treated EAE rats (score = 5). Melatonin caused a significant increase in serum IFN-gamma, in comparison to PBS-treated EAE rats whereas no considerable change in IL-4 levels were found, although they were significantly lower than those of controls. The ratio of IFN-gamma/IL-4, an indicator of Th-1/Th-2, was significantly higher in PBS- and melatonin- treated EAE rats, in comparison to controls. Moreover, results showed increased lymphocyte infiltration, activated astrocytes (GFAP+ cells) but also higher demyelinated plaques (MBP-deficient areas) in the lumbar spinal cord of melatonin-treated EAE rats. Finally, serum levels of lactate, but not melatonin, significantly increased in the melatonin group, compared to untreated EAE and normal rats. In conclusion, our results indicated a relationship between age and the development of EAE since a negative impact was found for melatonin on EAE recovery of young rats by enhancing IFN gamma, the ratio of Th1/Th2 cells, and astrocyte activation, which seems to delay the remyelination process. While melatonin levels decline in MS patients, lactate might be a potential diagnostic biomarker for prediction of disease progression. Early administration of melatonin in the acute phase of MS might be harmful and needs further investigations. PMID- 27696475 TI - A randomized and double-blind controlled trial evaluating the safety and efficacy of rituximab for warm auto-immune hemolytic anemia in adults (the RAIHA study). AB - This Phase 3 multicentre randomized double-blind and placebo-controlled trial aimed to compare the efficacy and safety of rituximab (RTX) to placebo for treating newly diagnosed warm autoimmune hemolytic anemia (wAIHA) in adults receiving prednisone. Adults with a confirmed diagnosis of wAIHA who previously received corticosteroids for less than 6 weeks could be included. At inclusion, all patients received prednisone at a daily dose of 1 mg/kg for 2 weeks, and then tapered according to a pre-defined recommended reduction scheme. Besides prednisone, eligible patients received 2 infusions of RTX or placebo at a fixed dose of 1,000 mg 2-week apart. The primary endpoint was overall response rate (complete response [CR] + partial response [PR]) in an intent-to-treat (ITT) analysis at 1 year. A total of 32 patients (17 females [53%], mean age at inclusion 71 +/- 16 years) were enrolled and randomized. In all, 27 patients were followed for at least 1 year and their data were evaluable for response. With an ITT analysis, the overall response rate at 1 year was 75% [95%CI: 47.6-92.7] with 11 CR and 1 PR with RTX versus 31% [11.0-58.7] (5 CR) with placebo (P = 0.032). At 2 years, 10/16 patients with RTX versus 3/16 with placebo still showed CR (P = 0.011). Overall, eight severe infections occurred during follow-up, six with placebo and two with RTX (P = 0.39). At 2 years, six patients with placebo had died, but none with RTX (P = 0.017). Compared to placebo, RTX combined with prednisone may be effective and safe for treating newly-diagnosed wAIHA in adults. Am. J. Hematol. 92:23-27, 2017. (c) 2016 Wiley Periodicals, Inc.

PMID- 27696476 TI - Radiosynthesis of novel pitavastatin derivative ([18 F]PTV-F1) as a tracer for hepatic OATP using a one-pot synthetic procedure. AB - Pitavastatin is an antihyperlipidemic agent, a potent inhibitor of 3 hydroxymethyl-glutaryl-CoA reductase, which is selectively taken up into the liver mainly via hepatic organic anion transporting polypeptide 1B1 (OATP1B1). OATP1B1 can accept a variety of organic anions, and previous reports indicated that it is responsible for the hepatic clearance of several clinically used anionic drugs. Therefore, the pharmacokinetics and the hepatic distribution of pitavastatin provide an insight into the function of OATP1B1 in humans. For the development of the in vivo evaluation of OATP1B1 function by positron emission tomography imaging, we designed a novel [18 F]pitavastatin derivative ([18 F]PTV F1), in which a [18 F]fluoroethoxy group is substituted for the [18 F]fluoro group of [18 F]pitavastatin, with the aim of convenient radiolabeling protocol and high radiochemical yield. In vitro studies suggested that transport activities of PTV-F1 mediated by OATP1B1 and OATP1B3 were very similar to those of pitavastatin and PTV-F1 was metabolically stable in human liver microsomes. In the radiosynthesis of [18 F]PTV-F1 from the tosylate precursor, nucleophilic fluorination and subsequent deprotection were performed using a one-pot procedure. [18 F]PTV-F1 was obtained with a radiochemical yield of 45% +/- 3% (n = 3), and the operating time for the radiosynthesis of [18 F]PTV-F1 is very short (30 minutes) compared with [18 F]pitavastatin.

PMID- 27696482 TI - Prostate Cancer Cells in Different Androgen Receptor Status Employ Different Leucine Transporters. AB - BACKGROUND: Leucine stimulates cancer cell proliferation through the mTOR pathway, therefore, inhibiting leucine transporters may be a novel therapeutic target for cancer. L-type amino acid transporter (LAT) 1, a Na+ -independent amino acid transporter, is highly expressed in many tumor cells. However, leucine transporter(s) in different stages of prostate cancer, particularly in the stages of castration resistance with androgen receptor (AR) expression, is unclear. METHODS: LNCaP and DU145 and PC-3 cell lines were used as a model of androgen dependent, and metastatic prostate cancer. A new "LN-cr" cell line was established after culturing LNCaP cells for 6 months under androgen-free conditions, which is considered a model of castration resistant prostate cancer (CRPC) with androgen AR expression. The expression of leucine transporters was investigated with quantitative PCR and immunofluorescence. Uptake of 14 C Leucine was examined in the presence or absence of BCH (a pan-LAT inhibitor), JPH203 (an LAT1-specific inhibitor), or Na+ . Cell growth was assessed with MTT assay. siRNA studies were performed to evaluate the indispensability of y+ LAT2 on leucine uptake and cell viability in LN-cr. RESULTS: Cell viability showed a 90% decrease in the absence of leucine in all four cell lines. LNCaP cells principally expressed LAT3, and their leucine uptake was more than 90% Na+ -independent. BCH, but not JPH203, inhibited leucine uptake, and cell proliferation (IC50BCH :15 mM). DU145 and PC-3 cells predominantly expressed LAT1. Leucine uptake and cell growth were suppressed by BCH or JPH203 in a dose-dependent manner (IC50BCH : ~20 mM, IC50JPH203 : ~5 uM). In LN-cr cells, Na+ -dependent uptake of leucine was 3.8 pmol/mgprotein/min, while, Na+ -independent uptake was only 0.52 (P < 0.05). Leucine uptake of LN-cr was largely (~85%) Na+ -dependent. y+ LAT2 expression was confirmed in LN-cr. Knockdown of y+ LAT2 lead to significant leucine uptake inhibition (40%) and cell growth inhibition (20%). CONCLUSIONS: New CRPC cell line with increased expression of y+ LAT2 as a leucine transporter was established in vitro. Anti-leucine transporter therapy could be an important option against prostate cancer. Prostate 77:222-233, 2017. (c) 2016 Wiley Periodicals, Inc.

AB - The Government of India is accepted to participate in the measles elimination and rubella control goal 2020, hence genetic characterization of measles viruses (MeV) becomes essential. At National Reference Laboratory (National Institute of Virology, Pune), the throat swabs/urine specimens (n = 380) or PCR products (n = 219) obtained from the suspected measles cases were referred for the molecular testing and subsequently, MeV nucleoprotein (N) gene sequencing/genotyping. In addition, 2,449 suspected measles cases, mainly from the Maharashtra state were referred for the laboratory diagnosis. A detailed study was performed on N gene sequences obtained during last two decades. Indian MeV sequences obtained during 2011-2015 were compared with 1996-2010 sequences and genetic divergence was studied. Circulation of measles genotypes B3 (n = 3), D4 (n = 49), and D8 (n = 351) strains were observed in 19 States and three Union Territories of India. In addition, 64 measles viruses were isolated from 253 throat swab or urine specimens obtained from the suspected measles cases. During 2011-2015, 67.9% (1,663/2,449) suspected measles cases were laboratory confirmed. Molecular studies showed circulation of measles genotype B3 in India along with prominently circulating genotypes D4 and D8 except D7 strains. The genetic diversion within Indian B3, D4, and D8 genotypes was 0.3%, 1.1%, and 2.1%, respectively. The genetic divergence of Indian B3, D4, and D8 measles strains with the WHO reference sequences was 2.5%, 2.6%, and 1.8%, respectively. It is crucial data for national immunization program. More measles/rubella genotyping studies are necessary to track transmission and to support measles elimination and rubella control. J. Med. Virol. 89:753-758, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27696483 TI - Incidence and impact of subclinical epileptiform activity in Alzheimer's disease. AB - OBJECTIVE: Seizures are more frequent in patients with Alzheimer's disease (AD) and can hasten cognitive decline. However, the incidence of subclinical epileptiform activity in AD and its consequences are unknown. Motivated by results from animal studies, we hypothesized higher than expected rates of subclinical epileptiform activity in AD with deleterious effects on cognition. METHODS: We prospectively enrolled 33 patients (mean age, 62 years) who met criteria for AD, but had no history of seizures, and 19 age-matched, cognitively normal controls. Subclinical epileptiform activity was assessed, blinded to diagnosis, by overnight long-term video-electroencephalography (EEG) and a 1-hour resting magnetoencephalography exam with simultaneous EEG. Patients also had comprehensive clinical and cognitive evaluations, assessed longitudinally over an average period of 3.3 years. RESULTS: Subclinical epileptiform activity was detected in 42.4% of AD patients and 10.5% of controls (p = 0.02). At the time of monitoring, AD patients with epileptiform activity did not differ clinically from those without such activity. However, patients with subclinical epileptiform activity showed faster declines in global cognition, determined by the Mini Mental State Examination (3.9 points/year in patients with epileptiform activity vs 1.6 points/year in patients without; p = 0.006), and in executive function (p = 0.01). INTERPRETATION: Extended monitoring detects subclinical epileptiform activity in a substantial proportion of patients with AD.

PMID- 27696487 TI - Core skeletal muscle ryanodine receptor calcium release complex. AB - The core skeletal muscle ryanodine receptor (RyR1) calcium release complex extends through three compartments of the muscle fibre, linking the extracellular environment through the cytoplasmic junctional gap to the lumen of the internal sarcoplasmic reticulum (SR) calcium store. The protein complex is essential for skeletal excitation-contraction (EC)-coupling and skeletal muscle function. Its importance is highlighted by perinatal death if any one of the EC-coupling components are missing and by myopathies associated with mutation of any of the proteins. The proteins essential for EC-coupling include the DHPR alpha1S subunit in the transverse tubule membrane, the DHPR beta1a subunit in the cytosol and the RyR1 ion channel in the SR membrane. The other core proteins are triadin and junctin and calsequestrin, associated mainly with SR. These SR proteins are not essential for survival but exert structural and functional influences that modify the gain of EC-coupling and maintain normal muscle function. This review summarises our current knowledge of the individual protein/protein interactions within the core complex and their overall contribution to EC-coupling. We highlight significant areas that provide a continuing challenge for the field. Additional important components of the Ca2+ release complex, such as FKBP12, calmodulin, S100A1 and Stac3 are identified and reviewed elsewhere.

AB - Glandular and pseudoglandular tumors of the penile skin are extremely uncommon and can present diagnostic challenges. Primary adenosquamous carcinoma of the penis is an extremely rare tumor, composed of distinct areas of malignant squamous and glandular cells, making it a diagnostically challenging entity. The World Health Organization (WHO) recognizes several subtypes of squamous cell carcinoma (SCC), each with its own distinctive pathologic appearance, clinical associations and prognosis. Among these variants is the exceedingly uncommon adenosquamous carcinoma (ASC), representing 1%-2% of all SCC of the penis. Recent large studies have interrogated the presence of human papillomavirus (HPV) in malignant penile tumors and have shown specific morphologic patterns and clinical presentations to associate with HPV status. However, given the rarity of the adenosquamous variant of SCC, it has largely been excluded from these studies. The glandular components of these lesions can present a confusing appearance, particularly when a large tumor is represented on a small biopsy. Here we describe a difficult histologic presentation of this rare tumor, with the first published characterization of the HPV status of this subtype. This case represents a distinctly unusual case of metastatic HPV-positive primary cutaneous adenosquamous carcinoma of the penis. PMID- 27696486 TI - Nucleotide Excision Repair: Finely Tuned Molecular Orchestra of Early Pre incision Events. AB - Nucleotide excision repair (NER) eliminates a broad variety of helix-distorting DNA lesions that can otherwise cause genomic instability. NER comprises two distinct subpathways: global genomic NER (GG-NER) operating throughout the genome, and transcription-coupled NER (TC-NER) preferentially removing DNA lesions from transcribing DNA strands of transcriptionally active genes. Several NER factors undergo post-translational modifications, including ubiquitination, occurring swiftly and reversibly at DNA lesion sites. Accumulating evidence indicates that ubiquitination not only orchestrates the spatio-temporal recruitment of key protein factors to DNA lesion sites but also the productive assembly of NER pre-incision complex. This review will be restricted to the latest conceptual understanding of ubiquitin-mediated regulation of initial damage sensors of NER, that is DDB, XPC, RNAPII and CSB. We project hypothetical NER models in which ubiquitin-specific segregase, valosin-containing protein (VCP)/p97, plays an essential role in timely extraction of the congregated DNA damage sensors to functionally facilitate the DNA lesion elimination from the genome.

PMID- 27696490 TI - Response surface modelling of the pharmacodynamic interaction between propofol and remifentanil in patients undergoing anaesthesia. AB - This study describes the pharmacodynamic interaction between propofol and remifentanil. Sixty patients who were scheduled for elective surgery under general anaesthesia (30 males/30 females) were enrolled. Patients were randomly allocated to receive one of 15 combinations of drug levels. Baseline electroencephalograms (EEGs) were recorded for 5 minutes prior to administering the drugs. Patients received a target-controlled infusion at one of four predefined doses of propofol (high, 3 MUg/mL; medium, 1.5 MUg/mL; low, 0.5 MUg/mL; or no drug) and of remifentanil (high, 6 or 8 ng/mL; medium, 4 ng/mL; low, 2 ng/mL; or no drug). The occurrence of muscle rigidity, apnoea, and loss of consciousness (LOC) was monitored, and EEGs were recorded during the drug administration phase. Electroencephalographic approximate entropy (ApEn) and temporal linear mode complexity (TLMC) parameters at baseline and under steady state conditions were calculated off-line. Response surfaces were developed to map the interaction between propofol and remifentanil to the probability of occurrence for quantal responses (muscle rigidity, apnoea, LOC) and ApEn and TLMC measurements. Model parameters were estimated using non-linear mixed effects modelling. The response surface revealed infra-additive and synergistic effects for muscle rigidity and apnoea, respectively. The effects of the combined drugs on LOC and EEG parameters (eg, ApEn and TLMC) were additive. The C50 estimates of remifentanil (ng/mL) and propofol (MUg/mL) were 9.11 and 130 000 for muscle rigidity, 8.99 and 6.26 for apnoea, 13.9 and 3.04 for LOC, 23.4 and 10.4 for ApEn, and 14.8 and 6.51 for TLMC, respectively. The probability of occurrence for muscle rigidity declined when propofol was combined with remifentanil. PMID- 27696492 TI - IIS 2015 Princeton Conference. PMID- 27696491 TI - Age and gender differences in self-control and its intergenerational transmission. AB - BACKGROUND: Few studies have been conducted in people of Asian descent that have reported to demonstrate the distinct developmental trends in good self-control and poor control. To fill this gap, we conducted a national cross-sectional survey among adolescents and young adults in China to further clarify the age and gender differences in self-control from a dual-systems perspective. METHODS: A total of 2910 adolescents (female, n = 1698) and their parents from five different provinces in China were surveyed using the Dual-Modes of Self-Control Scale (DMSC-S) and the Parents' Perceived Self-Control Scale. The mean age of the adolescent sample was 17.47 years (ranging from 12.50 to 25.42 years). RESULTS: Boys exhibited greater good self-control than girls. Poor control increased between 12 and 17 years of age and declined thereafter; however, good self control increased over the entire study period. Both good self-control and poor control in student participants were significantly associated with parents' perceived self-control; moreover, the association between good self-control and parental self-control was mediated by SES. CONCLUSION: The roles of age, gender, parental self-control and SES varied in a dual-systems model of self-control: good self-control and poor control. Implications of these results are discussed. PMID- 27696493 TI - Time trends in the health care burden and mortality of acute on chronic liver failure in the United States. AB - : Acute on chronic liver failure (ACLF) is associated with multisystem organ failure and poor prognosis in hospitalized patients with cirrhosis. We aimed to determine time trends in the epidemiology, economic burden, and mortality of ACLF in the United States. The National Inpatient Sample database was queried between 2001 and 2011. ACLF was defined as two or more extrahepatic organ failures in patients with cirrhosis. The primary outcomes were trends in hospitalizations, hospital costs, and inpatient mortality. The number of hospitalizations for cirrhosis in the United States nearly doubled from 371,000 in 2001 to 659,000 in 2011. The prevalence of ACLF among those hospitalizations increased from 1.5% (n = 5,400) to 5% (n = 32,300). The inpatient costs increased 2-fold for cirrhosis ($4.8 billion to $9.8 billion) and 5-fold ($320 million to $1.7 billion) for ACLF. In 2011, the cost per hospitalization for ACLF was 3.5-fold higher than that for cirrhosis ($53,570 versus $15,193). The in-hospital fatality rates decreased from 65% to 50% for ACLF and from 10% to 7% for cirrhosis. The organ failure trends in ACLF showed an increasing proportion of cardiovascular and cerebral and decreasing proportion of respiratory and renal failure. Age, male sex, and the number and types of organ failure were predictors of death in ACLF. CONCLUSION: Cirrhosis and ACLF represent a substantial and increasing health and economic burden in the United States; these data highlight an urgent need for research on pathophysiological mechanisms and effective therapy as well as for education of health care providers of its importance in the care of patients with cirrhosis.

AB - Staurozoan cnidarians display an unusual combination of polyp and medusa characteristics and their morphology may be informative about the evolutionary origin of medusae. We studied neuromuscular morphology of two staurozoans, Haliclystus 'sanjuanensis' and Manania handi, using whole mount immunohistochemistry with antibodies against FMRFamide and alpha-tubulin to label neurons and phalloidin to label muscles. All muscles appeared to lack striations. Longitudinal interradial muscles are probable homologues of stalk muscles in scyphopolyps, but in adult staurozoans they are elaborated to inwardly flex marginal lobes of the calyx during prey capture; these muscles are pennate in M. handi. Manubrial perradial muscles, like the manubrium itself, are an innovation shared with pelagic medusae and manubrial interradial muscles are shared with scyphozoan ephyra. Marginal muscles of M. handi displayed occasional synchronous contraction reminiscent of a medusa swim pulse, but contractions were not repetitive. The nerve net in both species showed regional variation in density and orientation of neurons. Some areas labeled predominantly by alpha-tubulin antibodies (exumbrellar epidermis), other areas labeled exclusively by FMRFamide antibodies (dense plexus of neurites surrounding the base of secondary tentacles, neuronal concentration at the base of transformed primary tentacles; gastrodermal nerve net), but most areas showed a mix of neurons labeled by these two antibodies and frequent co-labeling of neurons. Transformed primary tentacles had a concentration of FMRFamide-immunoreactive neurons at their base that was associated with a pigment spot in M. handi; this is consistent with their homology with rhopalia of medusae, which are also derived from primary tentacles. The muscular system of these staurozoans embodies characteristics of both scyphopolyps and pelagic medusae. However, their nerve net is more polyp-like, although marginal concentrations of the net associated with primary and secondary tentacles may facilitate the richer behavioral repertoire of staurozoans relative to polyps of other medusozoans.

AB - OBJECTIVE: While androgen deprivation therapy (ADT) has been associated with decreased quality of life (QoL), controlled prospective studies are lacking. We aimed to assess QoL during ADT using two validated questionnaires and determine contributing factors. DESIGN: Prospective controlled study. PATIENTS: Sixty-three men with nonmetastatic prostate cancer newly commencing ADT (n = 34) and age- and radiotherapy-matched prostate cancer controls (n = 29). MEASUREMENTS: QoL was measured by Short-Form 12 version 2 survey (SF-12) and Aging Males' Symptoms (AMS) score at 0, 6 and 12 months. Generalized linear models determined the mean adjusted difference (MAD) (95% confidence interval) between groups during follow up. RESULTS: Compared to controls over 12 months, men receiving ADT had decreased SF-12 physical component score [MAD -3.61 (-6.94, -0.29), P = 0.013] reflecting worsening QoL but no change in the mental component (P = 0.74). Total AMS score increased [MAD 9.35 (5.65, 13.07), P < 0.001], reflecting worse QoL. Both SF-12 and AMS changes were greater than reported minimum clinically important differences. AMS sub-domains showed increased somatic [MAD 3.96 (1.94, 5.99), P < 0.001] and sexual [MAD 3.80 (2.16, 5.44), P < 0.001] components but not psychological (P = 0.19). Decrements were related to an increase in hot flushes (P = 0.016) but not haemoglobin decrease (P = 0.46). CONCLUSIONS: Within 12 months, ADT is associated with clinically significant decreased QoL, particularly physical and sexual aspects, independent of the confounding effects of a cancer diagnosis or radiotherapy. As QoL is a crucial aspect of prostate cancer treatment, addressing hot flushes, sexual dysfunction and exercise may potentially improve outcomes for men undergoing ADT.

PMID- 27696497 TI - Cofactors-loaded quaternary structure of lysine-specific demethylase 5C (KDM5C) protein: Computational model. AB - The KDM5C gene (also known as JARID1C and SMCX) is located on the X chromosome and encodes a ubiquitously expressed 1560-aa protein, which plays an important role in lysine methylation (specifically reverses tri- and di-methylation of Lys4 of histone H3). Currently, 13 missense mutations in KDM5C have been linked to X linked mental retardation. However, the molecular mechanism of disease is currently unknown due to the experimental difficulties in expressing such large protein and the lack of experimental 3D structure. In this work, we utilize homology modeling, docking, and experimental data to predict 3D structures of KDM5C domains and their mutual arrangement. The resulting quaternary structure includes KDM5C JmjN, ARID, PHD1, JmjC, ZF domains, substrate histone peptide, enzymatic cofactors, and DNA. The predicted quaternary structure was investigated with molecular dynamic simulation for its stability, and further analysis was carried out to identify features measured experimentally. The predicted structure of KDM5C was used to investigate the effects of disease-causing mutations and it was shown that the mutations alter domain stability and inter-domain interactions. The structural model reported in this work could prompt experimental investigations of KDM5C domain-domain interaction and exploration of undiscovered functionalities. Proteins 2016; 84:1797-1809.

AB - OBJECTIVE: The aim of this study was to assess the performance of the revised New Zealand (NZ) newborn screening TSH cut-offs for congenital hypothyroidism (CHT). METHODS: Screening data over 24 months were obtained from the NZ newborn metabolic screening programme, which utilizes a 2-tier system of direct clinical referral for infants with markedly elevated TSH, and second samples from those with mild TSH elevation. We evaluated the impact of a reduced TSH threshold (50 to 30 mIU/l blood) for direct notification and a lower cut-off (15 to 8 mIU/l blood) applied to second samples and babies older than 14 days. RESULTS: In 2013 and 2014, 117 528 infants underwent newborn screening for CHT. Fifty-two CHT cases were identified by screening (47 general newborn population, five repeat testing in low-birth-weight infants) and one case was missed. Thirty-two infants with screening TSH >=30 mIU/l were directly referred at a median of 9 days (5-14) and 15 with TSH 15-29 mIU/l were referred after a second sample at a median of 20 days (9-52, P < 0.001). All directly referred infants were confirmed as CHT cases with no earlier referrals as a result of the reduced threshold. The lower TSH cut off applied to second samples lead to the identification of six extra cases of CHT (15% increase) from seven extra clinical referrals. CONCLUSIONS: The NZ screening programme achieved a 15% increase in CHT case detection for minimal increase in workload or anxiety for families of healthy infants. A further decrease in the threshold for direct referral may allow earlier diagnoses. PMID- 27696499 TI - Mohit's Pharmakon: Symptom, Rotational Bodies, and Pharmaceuticals in Rural Rajasthan. AB - This article reexamines medical anthropology theories of symptom, illness, and disease to consider unregulated medical care in India. It builds on clinical observations, an inventory of the pharmaceuticals used by men who call themselves "Bengali doctors," and their patients to understand medical care in a context that privileges symptom not disease. It draws on Derrida's use of pharmakon to outline the complexities of care and embodiment and helps locate local and medical anthropology theories of symptom and pharmaceuticals within theories of the experiential body. It asks two key questions: What is medical care without disease and what are its implications on a local biology in which disease-based biomedicine is modified? Searching for a tentative answer, it works to bring medical anthropology's interest in symptom back to the body without losing symptoms' connection to political economies, individual experience, and localized biomedicine. PMID- 27696500 TI - The rs2274911 polymorphism in GPRC6A gene is associated with insulin resistance in normal weight and obese subjects. AB - OBJECTIVE: Identification of the novel endocrine role of osteocalcin (OC) and its receptor GPRC6A has given rise to a new branch of research in OC/GPRC6A axis related to glucose metabolism. GPRC6A- and OC-deficient mice share features of the metabolic syndrome, in addition to male infertility. Recently, the polymorphism rs2274911 in GPRC6A was shown to be associated with testicular impairment. We aimed to investigate the role of rs2274911 polymorphism in glucose and lipid metabolism in a cohort of normal weight and obese subjects DESIGN, PATIENTS, SETTINGS: A total of 392 male and females, including 218 obese patients and 174 age-matched normal weight controls, were retrospectively selected. RESULTS: The distribution of rs2274911 alleles and genotypes did not differ either between normal weight and obese subjects or sexes (all P > 0.05). Age- and OC-adjusted multivariate analysis revealed that, in the normal weight group, fasting insulin and HOMA-IR increased in GA (P = 0.016 and P = 0.025) and AA genotypes (P = 0.033 and P = 0.040) compared with GG homozygotes. In the obese group, AA homozygotes had increased fasting glucose (P = 0.041 vs GG). Triglycerides, fasting insulin and HOMA-IR increased in both GA (P = 0.020, P < 0.001 and P = 0.001) and AA genotype (P = 0.021, P = 0.013 and P = 0.013). CONCLUSION: In a cohort of normal weight and obese subjects, we found that the nonrare polymorphism rs2274911 in the GPRC6A gene was associated with insulin resistance features, independently of the metabolic phenotype and OC levels.

AB - An imbalance in osteogenesis and adipogenesis is a crucial pathological factor in the development of osteoporosis. Many attempts have been made to develop drugs to prevent and treat this disease. In the present study, we investigated the phenomenon whereby downregulation of SLC7A11 significantly enhanced the osteogenic differentiation of mesenchymal stem cells (MSCs) in vitro, and promoted the bone formation in vivo. Sulfasalazine (SAS), an inhibitor of SLC7A11, increased the osteogenic potential effectively. Mechanistically, inhibition of SLC7A11 by SAS treatment or knockdown of SLC7A11 increased BMP2/4 expression dramatically. In addition, we detected increased Slc7a11 expression in bone marrow MSCs of ovariectomized (OVX) mice. Remarkably, SAS treatment attenuated bone loss in ovariectomized mice. Together, our data suggested that SAS could be used to treat osteoporosis by enhancing osteogenic differentiation of MSCs. (c) 2016 American Society for Bone and Mineral Research. PMID- 27696502 TI - High and low vitamin D level is associated with cardiovascular autonomic neuropathy in people with Type 1 and Type 2 diabetes. AB - AIM: To investigate the possible association between vitamin D deficiency and cardiovascular autonomic neuropathy in people with diabetes. METHODS: A total of 113 people with Type 1 or Type 2 diabetes [mean (interquartile range) diabetes duration 22.0 (12-31) years, mean (sd) age 56.2 (13.0) years, 58% men] underwent vitamin D (D2 and D3) assessment, and were screened for cardiovascular autonomic neuropathy using three cardiovascular reflex tests [heart rate response to deep breathing (E/I ratio), to standing (30/15 ratio) and to the Valsalva manoeuvre] and assessment of 5-min resting heart rate and heart rate variability indices. RESULTS: We found an inverse U-shaped association between serum vitamin D level and E/I ratio, 30/15 ratio and three heart rate variability indices (P < 0.05). Vitamin D level was non-linearly associated with cardiovascular autonomic neuropathy diagnosis (P < 0.05 adjusted for age and sex). Linear regression models showed that an increase in vitamin D level from 25 to 50 nmol/l was associated with an increase of 3.9% (95% CI 0.1;7.9) in E/I ratio and 4.8% (95% CI 4.7;9.3) in 30/15 ratio. Conversely, an increase from 125 to 150 nmol/l in vitamin D level was associated with a decrease of 2.6% (95% CI -5.8;0.1) and 4.1% (95% CI -5.8;-0.5) in the respective outcome measures. CONCLUSIONS: High and low vitamin D levels were associated with cardiovascular autonomic neuropathy in people with diabetes. Future studies should explore this association and the efficacy of treating dysvitaminosis D to prevent cardiovascular autonomic neuropathy. PMID- 27696503 TI - Child behaviour problems and childhood illness: development of the Eczema Behaviour Checklist. AB - BACKGROUND/OBJECTIVES: Children with atopic dermatitis are at increased risk of both general behaviour problems, and those specific to the condition and its treatment. This can hamper the ability of parents to carry out treatment and manage the condition effectively. To date, there is no published instrument available to assess child behaviour difficulties in the context of atopic dermatitis management. Our aim was to develop a reliable and valid instrument to assess atopic dermatitis-specific child behaviour problems, and parents' self efficacy (confidence) for managing these behaviours. METHODS: The Eczema Behaviour Checklist (EBC) was developed as a 25-item questionnaire to measure (i) extent of behaviour problems (EBC Extent scale), and (ii) parents' self-efficacy for managing behaviour problems (EBC Confidence scale), in the context of child atopic dermatitis management. A community-based sample of 292 parents completed the EBC, measures of general behaviour difficulties, self-efficacy with atopic dermatitis management and use of dysfunctional parenting strategies. RESULTS: There was satisfactory internal consistency and construct validity for EBC Extent and Confidence scales. There was a negative correlation between atopic dermatitis specific behaviour problems and parents' self-efficacy for dealing with behaviours (r = -.53, p < .001). Factor analyses revealed a three-factor structure for both scales: (i) treatment-related behaviours; (ii) symptom-related behaviours; and (iii) behaviours related to impact of the illness. Variation in parents' self-efficacy for managing their child's atopic dermatitis was explained by intensity of illness-specific child behaviour problems and parents' self efficacy for dealing with the behaviours. CONCLUSIONS: The new measure of atopic dermatitis-specific child behaviour problems was a stronger predictor of parents' self-efficacy for managing their child's condition than was the measure of general child behaviour difficulties. Results provide preliminary evidence of reliability and validity of the EBC, which has potential for use in clinical and research settings, and warrant further psychometric evaluation. PMID- 27696504 TI - Green tea polyphenols require the mitochondrial iron transporter, mitoferrin, for lifespan extension in Drosophila melanogaster. AB - Green tea has been found to increase the lifespan of various experimental animal models including the fruit fly, Drosophila melanogaster. High in polyphenolic content, green tea has been shown to reduce oxidative stress in part by its ability to bind free iron, a micronutrient that is both essential for and toxic to all living organisms. Due to green tea's iron-binding properties, we questioned whether green tea acts to increase the lifespan of the fruit fly by modulating iron regulators, specifically, mitoferrin, a mitochondrial iron transporter, and transferrin, found in the hemolymph of flies. Publicly available hypomorph mutants for these iron regulators were utilized to investigate the effect of green tea on lifespan and fertility. We identified that green tea could not increase the lifespan of mitoferrin mutants but did rescue the reduced male fertility phenotype. The effect of green tea on transferrin mutant lifespan and fertility were comparable to w1118 flies, as observed in our previous studies, in which green tea increased male fly lifespan and reduced male fertility. Expression levels in both w1118 flies and mutant flies, supplemented with green tea, showed an upregulation of mitoferrin but not transferrin. Total body and mitochondrial iron levels were significantly reduced by green tea supplementation in w1118 and mitoferrin mutants but not transferrin mutant flies. Our results demonstrate that green tea may act to increase the lifespan of Drosophila in part by the regulation of mitoferrin and reduction of mitochondrial iron. PMID- 27696505 TI - Effectiveness of Africa's tropical protected areas for maintaining forest cover. AB - The effectiveness of parks for forest conservation is widely debated in Africa, where increasing human pressure, insufficient funding, and lack of management capacity frequently place significant demands on forests. Tropical forests house a substantial portion of the world's remaining biodiversity and are heavily affected by anthropogenic activity. We analyzed park effectiveness at the individual (224 parks) and national (23 countries) level across Africa by comparing the extent of forest loss (as a proxy for deforestation) inside parks to matched unprotected control sites. Although significant geographical variation existed among parks, the majority of African parks had significantly less forest loss within their boundaries (e.g., Mahale Park had 34 times less forest loss within its boundary) than control sites. Accessibility was a significant driver of forest loss. Relatively inaccessible areas had a higher probability (odds ratio >1, p < 0.001) of forest loss but only in ineffective parks, and relatively accessible areas had a higher probability of forest loss but only in effective parks. Smaller parks less effectively prevented forest loss inside park boundaries than larger parks (T = -2.32, p < 0.05), and older parks less effectively prevented forest loss inside park boundaries than younger parks (F2,154 = -4.11, p < 0.001). Our analyses, the first individual and national assessment of park effectiveness across Africa, demonstrated the complexity of factors (such as geographical variation, accessibility, and park size and age) influencing the ability of a park to curb forest loss within its boundaries. PMID- 27696506 TI - Echocardiographic assessment of right ventricular contractile reserve in healthy subjects. AB - BACKGROUND: Exercise-induced increase in pulmonary artery systolic pressure (PASP) as a possible measure of right ventricular (RV) contractile reserve has been shown to predict survival in severe pulmonary hypertension. However, RV contractile reserve can also be measured by changes in stroke volume (SV), tricuspid annular plane systolic excursion (TAPSE), or tricuspid annular systolic velocity (S'). The limits of normal values and the functional significance of these changes in healthy subjects are not well known. METHODS: In this prospective study, 90 healthy subjects (45 male, mean age 39 +/- 13 years) underwent exercise stress echocardiography with measurement of TAPSE, S', TAPSE/PASP, SV, and PASP at rest and peak exercise. Maximum and minimum normal values were reported for all indices. RESULTS: Normal values of exercise-induced changes (Delta) were 4 to 10 mm for TAPSE, 6 to 14 cm/s for S', 12 to 57 mm Hg for PASP, 0 to 96 mL for SV, and -1.2 to 0 mm/mm Hg for TAPSE/PASP. At peak exercise, women showed lower DeltaTAPSE/PASP, DeltaPASP, DeltaS', and DeltaSV, but higher TAPSE/PASP than men. Aging was associated with decreased DeltaTAPSE/PASP, DeltaTAPSE, DeltaS', DeltaPASP, and DeltaSV. In addition, DeltaS', DeltaTAPSE/PASP, DeltaPASP, and DeltaSV, but not DeltaTAPSE, were directly correlated with maximum workload. CONCLUSIONS: Our results provide age- and sex-related limits of normal for RV contractile reserve as assessed by exercise stress echocardiography and demonstrate that RV systolic function indices (PASP, TAPSE, S', and TAPSE/PASP) correlate with maximum exercise capacity.

AB - In Paralympic sport, classification of impairment is needed to prevent a one sided and predictable outcome of competition, in which the least impaired athlete has the best chance to win. To develop evidence-based classification in wheelchair rugby, the impact of trunk impairment, measured by the Trunk Impairment Classification (TIC), on performance-determining activities was assessed. Arm impairment was analyzed as a covariant. Fifty-five athletes, 21 with TIC score 0, 13 with TIC score 0.5, 11 with TIC score 1.0, and 10 with TIC score 1.5 performed standardized sport-specific activities. A multiple step forward regression analysis was performed for all activities to assess the relative impact of trunk and arm impairment on performance. Trunk impairment was the most important factor for tilting the chair and acceleration in the first 2 m. The explained variance of the performance by trunk and arm impairment ranged from 23% for acceleration in the first meter, to 37% for sprint momentum, the tilt test left, and the time to cover 3 and 4 m. This study shows that athletes with limited trunk impairment are more proficient in wheelchair rugby than athletes with severe trunk impairment. PMID- 27696508 TI - Analysis of synonymous codon usage patterns in the edible fungus Volvariella volvacea. AB - In this study, trends in synonymous codons usage of Volvariella volvecea have been first examined by analysis of complete coding sequences and gene chip data. The results showed that GC content at three codon positions are obviously different and there were several factors shaping the codon usage of V. volvacea genes, including base composition. The comparison of codon usage among four edible fungi such as V. volvacea, Agaricus bisporus, Coprinopsis cinerea, and Pleurotus ostreatus indicated that the similar codon usage pattern was used among V. volvacea, A. bisporus and P. ostreatus, but there was significantly different codon usage pattern of C. cinerea. Two arrays of optimal codons were determined by effective number of codons (ENC) values and gene chip database separately, resulting that most of the ENC-predicted optimal codons were included in the array of gene chip resulted optimal codons. This study can provide useful information for codon usage pattern analysis and gene transformation of V. volvacea.

AB - BACKGROUND: Skin hyperpigmentary disorders including postinflammatory hyperpigmentation, melasma, solar lentigines, and conditions like freckles are common. The light-emitting diodes (LEDs) are the latest category of nonthermal and noninvasive phototherapy to be considered in skin pigmentation disorder treatment. PURPOSE: The purpose of this study was to investigate the effects of 660-nm LED on inhibition of melanogenesis. We investigated whether a 660-nm LED affected melanin synthesis in in vitro and in vivo models, and we explored the mechanisms involved. METHODS: The inhibitory effect of 660-nm LED on melanin synthesis was evaluated in B16F10 cells and HRM-2 melanin-possessing hairless mice were used to evaluate the antimelanogenic effects of 660-nm LED. RESULTS: Interestingly, 660-nm LED inhibited alpha-melanocyte-stimulating hormone-induced tyrosinase activity in B16F10 cells. We also found that 660-nm LED decreased MITF and tyrosinase expression and induced the activation of ERK. These findings suggest that the depigmenting effects of 660-nm LED result from downregulation of MITF and tyrosinase expression due to increased ERK activity. The 660-nm LED reduced UVB-induced melanogenesis in the skin of HRM-2 via downregulation of tyrosinase and MITF. CONCLUSION: These findings suggest 660-nm LED is a potentially depigmentation strategy.

AB - Interest in stream mesocosms has recently revived for higher tier aquatic macrophyte risk assessment of plant protection products mainly because 1) the highest predicted environmental concentrations for the assessment of effects are frequently derived from stream scenarios, and 2) they allow an effect assessment using stream-typical pulse exposures. Therefore, the present stream mesocosm study used an herbicide pulse exposure and evaluated the responses of Elodea canadensis and Myriophyllum spicatum. Macrophytes were exposed for 24 h to 1 MUg/L, 3 MUg/L, 10 MUg/L, and 30 MUg/L of the herbicide iofensulfuron-sodium with a subsequent recovery period of 42 d. Biological endpoints were growth rates of the main, side, and total shoot length, the shoot number, the maximum root length, and the dry weight. The total shoot length was identified as the most sensitive endpoint; the growth rate of the total shoot length was inhibited by up to 66% and 45% in M. spicatum and E. canadensis, respectively. The lowest no observed effect concentrations (NOECs) were observed at day 7 and/or day 14 after herbicide treatment and were 1 MUg/L for M. spicatum and 3 MUg/L for E. canadensis. The no-observed-ecologically-adverse-effect concentrations (NOEAECs) were 10 MUg/L and 30 MUg/L for M. spicatum and E. canadensis, respectively. Such or similar mesocosm designs are useful to simulate typical stream exposures and estimate herbicide effects on aquatic macrophytes in stream systems. Environ Toxicol Chem 2017;36:1090-1100.

AB - BACKGROUND AND AIM: Long intergenic noncoding RNAs (lincRNAs) have critical roles in elevating efficacy of anticancer therapy and tumor progression. Recent studies show that Regulator of Reprogramming (ROR) is aberrantly expressed in several types of cancer, including colorectal cancer (CRC). Radiotherapy is considered as a standard preoperative treatment. However, a considerable number of CRCs are resistant to radiotherapy. In this study, we evaluated the role of lincRNA-ROR in radiotherapy for CRC and detected the underlying molecular mechanism. METHODS: Real-time polymerase chain reaction was employed to quantify the expression level of lincRNA-ROR in different CRC cell lines and tissue samples. Cell viability and apoptosis assays were used to confirm the radiotherapy-mediated effects by lincRNA-ROR altered expression. The direct impact of lincRNA-ROR on the expression of p53/miR-145 by loss-of-function and gain-of-function strategy was also analyzed. A xenograft mouse model was used to evaluate the role of linc-ROR in CRC treatment. RESULTS: We discovered that lincRNA-ROR was upregulated in CRC cell lines and tissue samples. We further showed that knockdown of lincRNA-ROR enhanced the sensitivity to radiotherapy for CRC by inhibiting cell viability and promoting apoptosis. Activity of the p53/miR-145 pathway may help explain the role of lincRNA-ROR for stress-induced regulation in CRC therapy. Combined specific knockdown of lincRNA-ROR and radiotherapy treatment in xenograft model resulted in a significant reduction in the tumor growth. CONCLUSION: LincRNA-ROR decreases sensitivity to radiotherapy via the negative regulation of p53/miR-145 and may represent a potential target for the treatment of CRC.

AB - The sphingosine kinase (SphK)/sphingosine 1-phosphate (S1P) pathway is involved in multiple biological processes, including carcinogenesis. Melatonin shows beneficial effects in cell and animal models of hepatocellular carcinoma, but it is unknown if they are associated with the modulation of the SphK/S1P system, along with different downstream signaling pathways modified in cancer. We investigated the effects of melatonin in mice which received diethylnitrosamine (DEN) (35 mg/kg body weight i.p) once a week for 8 weeks. Melatonin was given at 5 or 10 mg/kg/day i.p. beginning 4 weeks after the onset of DEN administration and ending at the sacrifice time (10, 20, 30, or 40 weeks). Melatonin alleviated the distortion of normal hepatic architecture, lowered the incidence of preneoplastic/neoplastic lesions, and inhibited the expression of proliferative/cell cycle regulatory proteins (Ki67, PCNA, cyclin D1, cyclin E, CDK4, and CDK6). S1P levels and expression of SphK1, SphK2, and S1P receptors (S1PR1/S1PR3) were significantly elevated in DEN-treated mice. However, there was a decreased expression of S1P lyase. These effects were significantly abrogated in a time- and dose-dependent manner by melatonin, which also increased S1PR2 expression. Following DEN treatment, mice exhibited increased phosphorylation of PI3K, AKT, mTOR, STAT3, ERK, and p38, and a higher expression of NF-kappaB p50 and p65 subunits. Melatonin administration significantly inhibited those changes. Data obtained suggest a contribution of the SphK/S1P system and related signaling pathways to the protective effects of melatonin in hepatocarcinogenesis. PMID- 27696513 TI - Is there an optimal preoperative management strategy for phaeochromocytoma/paraganglioma? AB - Phaeochromocytomas and paragangliomas (PPGLs) are catecholamine secreting neuroendocrine tumours that predispose to haemodynamic instability. Currently, surgery is the only available curative treatment, but carries potential risks including hypertensive and hypotensive crises, cardiac arrhythmias, myocardial infarction and stroke, due to tumoral release of catecholamines during anaesthetic induction and tumour manipulation. The mortality associated with surgical resection of PPGL has significantly improved from 20-45% in the early 20th century (Apgar & Papper, AMA Archives of Surgery, 1951, 62, 634) to 0-2.9% in the early 21st century (Kinney et al. Journal of Cardiothoracic and Vascular Anesthesia, 2002, 16, 359), largely due to availability of effective pharmacological agents and advances in surgical and anaesthetic practice. However, surgical resection of PPGL still poses significant clinical management challenges. Preoperatively, alpha-adrenoceptor blockade is the mainstay of management, although various pharmacological strategies have been proposed, based largely on reports derived from retrospective data sets. To date, no consensus has been reached regarding the 'ideal' preoperative strategy due, in part, to a paucity of data from high-quality evidence-based studies comparing different treatment regimens. Here, based on the available literature, we address the Clinical Question: Is there an optimal preoperative management strategy for PPGL? PMID- 27696514 TI - WEO position statement on hygiene in digestive endoscopy: Focus on endoscopy units in Asia and the Middle East. AB - The aim of this position statement is to reinforce the key points of hygiene in digestive endoscopy. The present article details the minimum hygiene requirements for reprocessing of endoscopes and endoscopic devices, regardless of the reprocessing method (automated washer-disinfector or manual cleaning) and the endoscopy setting (endoscopy suite, operating room, elective or emergency procedures). These minimum requirements are mandatory for patient safety. Both advanced diagnostic and therapeutic endoscopies should be carried out in an environment that is safe for patients and staff. Particular attention is given to contaminants. Procedural errors in decontamination, defective equipment, and failure to follow disinfection guidelines are major factors contributing to transmission of infection during endoscopy. Other important risk factors include inadequate cleaning, use of older endoscopes with surface and working channel irregularities, and contamination of water bottles or irrigating solutions. Infections by multidrug-resistant organisms have become an increasing problem in health-care systems worldwide. Since 2010, outbreaks of multidrug-resistant bacteria associated with endoscopic retrograde cholangiopancreatography have been reported from the USA, France, Germany, and The Netherlands. In many endoscopy units in Asia and the Middle East, reprocessing procedures have lagged behind those of Western countries for cultural reasons or lack of financial resources. This inconsistency in standards is now being addressed, and the World Endoscopy Organization has prepared this position statement to highlight key points for quality assurance in any endoscopy unit in any country. PMID- 27696516 TI - Fish bioconcentration studies with column-generated analyte concentrations of highly hydrophobic organic chemicals. AB - The performance of aqueous exposure bioconcentration fish tests according to Organisation for Economic Co-operation and Development (OECD) guideline 305 requires the possibility of preparing stable aqueous concentrations of the test substances. For highly hydrophobic organic chemicals (HOCs; octanol-water partition coefficient [log KOW ] > 5), testing via aqueous exposure may become increasingly difficult. A solid-phase desorption dosing system was developed to generate stable concentrations of HOCs without using solubilizing agents. The system was tested with hexachlorobenzene (HCB), o-terphenyl (oTP), polychlorinated biphenyl (PCB) 153, and dibenz[a,h]anthracene (DBA) (log KOW 5.5 7.8) in 2 flow-through fish tests with rainbow trout (Oncorhynchus mykiss). The analysis of the test media applied during the bioconcentration factor (BCF) studies showed that stable analyte concentrations of the 4 HOCs were maintained in the test system over an uptake period of 8 wk. Bioconcentration factors (L kg 1 wet wt) were estimated for HCB (BCF 35 589), oTP (BCF 12 040), and PCB 153 (BCF 18 539) based on total water concentrations. No bioconcentration could be determined for DBA, probably because of the rapid metabolism of the test item. The solid-phase desorption dosing system is suitable to provide stable aqueous concentrations of HOCs required to determine the bioconcentration in fish and represents a viable alternative to the use of solubilizing agents for the preparation of test solutions.

PMID- 27696515 TI - Bioaccumulation and trophodynamics of the antidepressants sertraline and fluoxetine in laboratory-constructed, 3-level aquatic food chains. AB - Although reports of pharmaceutical bioconcentration in aquatic organisms are increasing, less is known about trophic transfer in aquatic food webs. The bioaccumulation and trophodynamics of sertraline and fluoxetine, 2 selective serotonin reuptake inhibitors (SSRIs) frequently detected in aquatic environments, were tested by exposing constructed aquatic food chains to SSRIs under controlled laboratory conditions. Both of these ionizable, weak base pharmaceuticals showed lower bioaccumulation factors (BAFs) with increasing trophic level (i.e., no biomagnifications) in 2 3-level food chains (Acer platanoides, fed to Asellus aquaticus, in turn fed to Notonecta glauca or Pungitius pungitius). Mean sertraline BAFs in A. platanoides, A. aquaticus, N. glauca, and P. pungitus were 2200 L/kg, 360 L/kg, 26 L/kg, and 49 L/kg, respectively, and mean fluoxetine BAFs 1300 L/kg, 110 L/kg, 11 L/kg, and 41 L/kg, respectively. The weak influence of diet was further demonstrated by measured BAFs being equal to or lower than measured bioconcentration factors (BCFs). Organism lipid content was not positively correlated with BAFs, suggesting that other processes are driving interspecific differences in SSRI bioaccumulation. The empirically derived parameter values were introduced into a proposed bioaccumulation model, and a poor correlation was found between modeled and empirical BAFs (predicted r2 = -0.63). In conclusion, the apparent lack of biomagnification of these ionizable pharmaceuticals suggests that environmental concern should not necessarily focus only on higher trophic levels, but also on species showing high BCFs at any trophic level.

AB - PURPOSE: The inhomogeneity of flip angle distribution is a major challenge impeding the application of high-field MRI. We report a method combining spatially selective excitation using generalized spatial encoding magnetic fields (SAGS) with radiofrequency (RF) shimming to achieve homogeneous excitation. This method can be an alternative approach to address the challenge of B1+ inhomogeneity using nonlinear gradients. METHODS: We proposed a two-step algorithm that jointly optimizes the combination of nonlinear spatial encoding magnetic fields and the combination of multiple RF transmitter coils and then optimizes the locations, RF amplitudes, and phases of the spokes. RESULTS: Our results show that jointly designed SAGS and RF shimming can provide a more homogeneous flip angle distribution than using SAGS or RF shimming alone. Compared with RF shimming alone, our approach can reduce the relative standard deviation of flip angle by 56% and 52% using phantom and human head data, respectively. CONCLUSION: The jointly designed SAGS and RF shimming method can be used to achieve homogeneous flip angle distributions when fully parallel RF transmission is not available.

PMID- 27696519 TI - ALBI and PALBI grade predict survival for HCC across treatment modalities and BCLC stages in the MELD Era. AB - BACKGROUND AND AIM: The severity of liver dysfunction in hepatocellular carcinoma (HCC) is often estimated with Child-Turcotte-Pugh (CTP) classification or model for end-stage liver disease (MELD) score. We aim to investigate the performance of albumin-bilirubin (ALBI) and platelet-albumin-bilirubin (PALBI) grade, which are recently reported to be simple and objective measurements for liver reserve in HCC. METHODS: Between 2002 and 2014, consecutive 3182 HCC patients were enrolled to follow up their survival. The area under receiver-operator characteristic curve (AUC) was calculated to test the discriminatory powers over 1-year, 3-year, and 5-year survival. RESULTS: Significant survival differences were found across all ALBI and PALBI grades (both P < 0.001). The majority (73%) of patients were CTP class A. Within CTP class A, ALBI revealed two prognostic groups while PALBI segregated three prognostic groups. The PABLI grade also identified three different survival groups for patients undergoing resection, ablation, and chemoembolization. Both ALBI and PALBI grade were capable of discerning survival among different HCC stages. The PALBI grade had significantly higher AUC compared with CTP classification and ALBI grade at 1, 3, and 5 years. For CTP class A patients, the PALBI grade was also associated with significantly higher AUC compared with ALBI grade at 1-year and 3-year intervals. The MELD score has the lowest AUC compared with other systems. CONCLUSIONS: Both ALBI and PALBI grade are adequate models to assess liver dysfunction in HCC. The PALBI grade is consistently better in all patients, in patients with minimally decreased liver function, and in patients receiving different aggressive therapies. PMID- 27696520 TI - Psychological outcomes of evening and night closed-loop insulin delivery under free living conditions in people with Type 1 diabetes: a 2-month randomized crossover trial. AB - AIM: To assess the impact on fear of hypoglycaemia and treatment satisfaction with an artificial pancreas system used for 2 consecutive months, as well as participant acceptance of the artificial pancreas system. METHODS: In a randomized crossover trial patient-related outcomes associated with an evening and-night artificial pancreas and sensor-augmented pump therapy were compared. Both intervention periods lasted 8 weeks. The artificial pancreas acceptance questionnaire (range 0-90, higher scores better), Hypoglycaemia Fear Survey II (range 0-72, higher scores worse) and Diabetes Treatment Satisfaction Questionnaire (range 0-36, higher scores better) were completed by 32 participants. Semi-structured interviews were conducted after study completion in a subset of six participants. Outcomes were compared using a repeated-measures anova model or paired t-test when appropriate. RESULTS: The total artificial pancreas acceptance questionnaire score at the end of the artificial pancreas period was 69.1 (sd 14.7; 95% CI 63.5, 74.7), indicating a positive attitude towards the artificial pancreas. No significant differences were found among the scores at baseline, end of sensor-augmented pump therapy period or end of the artificial pancreas period with regard to fear of hypoglycaemia [28.2 (sd 17.5), 23.5 (sd 16.6) and 23.5 (sd 16.7), respectively; P = 0.099] or diabetes treatment satisfaction [29.0 (sd 3.9), 28.2 (sd 5.2) and 28.0 (sd 7.1), respectively; P = 0.43]. Themes frequently mentioned in the interviews were 'positive effects at work', 'improved blood glucose', 'fewer worries about blood glucose', but also 'frequent alarms', 'technological issues' and 'demand for an all-in-one device'. CONCLUSIONS: The psychological outcomes of artificial pancreas and sensor augmented pump therapy were similar. Current artificial pancreas technology is promising but user concerns should be taken into account to ensure utility of these systems. PMID- 27696522 TI - Parameters of Context-Induced Ethanol (EtOH)-Seeking in Alcohol-Preferring (P) Rats: Temporal Analysis, Effects of Repeated Deprivation, and EtOH Priming Injections. AB - BACKGROUND: Drug-paired environments can act as stimuli that elicit drug craving. In humans, drug craving is influenced by the amount of time abstinent, number of past periods of abstinence, and inadvertent exposure to the previously abused drug. The current experiments were designed to determine the effects of (i) the duration of abstinence on expression of ethanol (EtOH)-seeking; (ii) EtOH priming following a short and long abstinence period; and (iii) repeated deprivation cycles on relapse drinking and EtOH-seeking. METHODS: Rats were allowed to self administer 15% EtOH, processed through extinction training, maintained in a home cage for a designated EtOH-free period, and then reintroduced to the operant context in the absence of EtOH. The experiments examined the effects of: (i) various home-cage duration periods (1 to 8 weeks), (ii) priming injections of EtOH in the Pavlovian spontaneous recovery (PSR; 14 days after extinction) and reinstatement of responding (RoR; 1 day after extinction) models, and (iii) exposure to repeated cycles of EtOH access-deprivation on relapse drinking and EtOH-seeking behavior. RESULTS: Highest expression of EtOH-seeking was observed following 6 weeks of home-cage maintenance. Priming injections of EtOH were more efficacious at stimulating/enhancing EtOH-seeking in the PSR than RoR model. Exposure to repeated cycles of EtOH deprivation and access enhanced and prolonged relapse drinking and the expression of EtOH-seeking (318 +/- 22 responses), which was not observed in rats given equivalent consistent exposure to EtOH (66 +/- 11 responses). CONCLUSIONS: Overall, the data indicated that the PSR model has ecological validity; factors that enhance EtOH craving in humans enhance the expression of EtOH-seeking in the PSR test. The data also detail factors that need to be examined to determine the biological basis of EtOH-seeking (e.g., neuroadaptations that occur during the incubation period and following repeated cycles of EtOH drinking and abstinence).

AB - Melatonin reportedly protects against several cardiovascular diseases including ischemia/reperfusion (I/R), atherosclerosis, and hypertension. The present study investigated the effects and mechanisms of melatonin on cardiomyocyte autophagy, apoptosis, and mitochondrial injury in the context of myocardial infarction (MI). We demonstrated that melatonin significantly alleviated cardiac dysfunction after MI. Four weeks after MI, echocardiography and Masson staining indicated that melatonin notably mitigated adverse left ventricle remodeling. The mechanism may be associated with increased autophagy, reduced apoptosis, and alleviated mitochondrial dysfunction. Furthermore, melatonin significantly inhibited Mst1 phosphorylation while promoting Sirt1 expression after MI, which indicates that Mst1/Sirt1 signaling may serve as the downstream target of melatonin. We thus constructed a MI model using Mst1 transgenic (Mst1 Tg) and Mst1 knockout (Mst1-/- ) mice. The absence of Mst1 abolished the favorable effects of melatonin on cardiac injury after MI. Consistently, melatonin administration did not further increase autophagy, decrease apoptosis, or alleviate mitochondrial integrity and biogenesis in Mst1 knockout mice subjected to MI injury. These results suggest that melatonin alleviates postinfarction cardiac remodeling and dysfunction by upregulating autophagy, decreasing apoptosis, and modulating mitochondrial integrity and biogenesis. The attributed mechanism involved, at least in part, Mst1/Sirt1 signaling. PMID- 27696526 TI - Body composition in pituitary, adrenal and iatrogenic Cushing's syndrome and effects of DHEAS levels.

AB - BACKGROUND: Longitudinal melanonychia might be difficult to differentiate and the use of dermoscopy can be useful for the preoperative evaluation and management decision. OBJECTIVES: The aim of our study was to investigate clinical and dermoscopic criteria of acquired longitudinal melanonychia in adults to identify the best predictors of melanoma using a multivariate analysis and to explore eventual new dermoscopic criteria for nail melanoma diagnosis. METHODS: In this retrospective observational study, 82 histopathologically diagnosed, acquired nail pigmented bands were collected and examined. All variables were included in the analysis and examined as possible predictors of nail melanoma. Both univariate and multivariable analyses have been performed. RESULTS: Among 82 cases, 25 were diagnosed as nail melanoma and 57 as benign lesions (including 32 melanocytic nevi and 25 benign melanocytic hyperplasia). Melanoma cases were significantly associated with a width of the pigmented band higher than 2/3 of the nail plate, grey and black colours, irregularly pigmented lines, Hutchinson and micro-Hutchinson signs, and nail dystrophy. Granular pigmentation, a newly defined dermoscopic criterion, was found in 40% of melanomas and only in 3.51% of benign lesions. CONCLUSIONS: Dermoscopic examination of longitudinal melanonychia provides useful information that could help clinicians to improve melanoma recognition.

AB - To evaluate the potential of algal biotechnology to replace traditional agriculture in northeastern Thailand, an open raceway cultivation system was developed to produce biomass and beta-carotene. Dunaliella salina KU 11 isolated from local saline soil was cultured in open raceway tanks using brine and saline lake water. Grown in modified Johnson's medium (with 2-3.5 M NaCl), the algae reached a maximum cell density on the fourth day (1.8 * 106 cells mL-1 ). Increasing KNO3 and NaHCO3 from 0.5 and 0.043 g L-1 to 1 and 2.1 g L-1 , respectively, significantly improved the yields of biomass (0.33 g L-1 ) and beta carotene (19 mg L-1 ). Expected profits for algal production were evaluated, and it was found that this strain was suitable for outdoor cultivation and the developing algal industry in northeastern Thailand could produce high economic benefits (at least $64,120 per year per 0.16 ha). PMID- 27696527 TI - Differential Kv1.3, KCa3.1, and Kir2.1 expression in "classically" and "alternatively" activated microglia. AB - Microglia are highly plastic cells that can assume different phenotypes in response to microenvironmental signals. Lipopolysaccharide (LPS) and interferon gamma (IFN-gamma) promote differentiation into classically activated M1-like microglia, which produce high levels of pro-inflammatory cytokines and nitric oxide and are thought to contribute to neurological damage in ischemic stroke and Alzheimer's disease. IL-4 in contrast induces a phenotype associated with anti inflammatory effects and tissue repair. We here investigated whether these microglia subsets vary in their K+ channel expression by differentiating neonatal mouse microglia into M(LPS) and M(IL-4) microglia and studying their K+ channel expression by whole-cell patch-clamp, quantitative PCR and immunohistochemistry. We identified three major types of K+ channels based on their biophysical and pharmacological fingerprints: a use-dependent, outwardly rectifying current sensitive to the KV 1.3 blockers PAP-1 and ShK-186, an inwardly rectifying Ba2+ sensitive Kir 2.1 current, and a Ca2+ -activated, TRAM-34-sensitive KCa 3.1 current. Both KV 1.3 and KCa 3.1 blockers inhibited pro-inflammatory cytokine production and iNOS and COX2 expression demonstrating that KV 1.3 and KCa 3.1 play important roles in microglia activation. Following differentiation with LPS or a combination of LPS and IFN-gamma microglia exhibited high KV 1.3 current densities (~50 pA/pF at 40 mV) and virtually no KCa 3.1 and Kir currents, while microglia differentiated with IL-4 exhibited large Kir 2.1 currents (~ 10 pA/pF at -120 mV). KCa 3.1 currents were generally low but moderately increased following stimulation with IFN-gamma or ATP (~10 pS/pF). This differential K+ channel expression pattern suggests that KV 1.3 and KCa 3.1 inhibitors could be used to inhibit detrimental neuroinflammatory microglia functions. GLIA 2016;65:106-121. PMID- 27696523 TI - Alcohol Use and Human Immunodeficiency Virus (HIV) Infection: Current Knowledge, Implications, and Future Directions. AB - Alcohol use is common among people living with human immunodeficiency virus (HIV). In this narrative review, we describe literature regarding alcohol's impact on transmission, care, coinfections, and comorbidities that are common among people living with HIV (PLWH), as well as literature regarding interventions to address alcohol use and its influences among PLWH. This narrative review identifies alcohol use as a risk factor for HIV transmission, as well as a factor impacting the clinical manifestations and management of HIV. Alcohol use appears to have additive and potentially synergistic effects on common HIV-related comorbidities. We find that interventions to modify drinking and improve HIV-related risks and outcomes have had limited success to date, and we recommend research in several areas. Consistent with Office of AIDS Research/National Institutes of Health priorities, we suggest research to better understand how and at what levels alcohol influences comorbid conditions among PLWH, to elucidate the mechanisms by which alcohol use is impacting comorbidities, and to understand whether decreases in alcohol use improve HIV relevant outcomes. This should include studies regarding whether state-of-the-art medications used to treat common coinfections are safe for PLWH who drink alcohol. We recommend that future research among PLWH include validated self report measures of alcohol use and/or biological measurements, ideally both. Additionally, subgroup variation in associations should be identified to ensure that the risks of particularly vulnerable populations are understood. This body of research should serve as a foundation for a next generation of intervention studies to address alcohol use from transmission to treatment of HIV. Intervention studies should inform implementation efforts to improve provision of alcohol-related interventions and treatments for PLWH in healthcare settings. By making further progress on understanding how alcohol use affects PLWH in the era of HIV as a chronic condition, this research should inform how we can mitigate transmission, achieve viral suppression, and avoid exacerbating common comorbidities of HIV and alcohol use and make progress toward the 90-90-90 goals for engagement in the HIV treatment cascade. PMID- 27696532 TI - Uptake of parasite-derived vesicles by astrocytes and microglial phagocytosis of infected erythrocytes may drive neuroinflammation in cerebral malaria. AB - Astrocytes and microglia are activated during cerebral malaria (CM) and contribute to the production and release of several mediators during neuroinflammatory processes. Whether these changes are the consequence of a direct crosstalk between glial cells and the malarial parasite and how these cells participate in the pathogenesis of CM is not yet clear. We therefore examined the interaction of astrocytes and microglia with Plasmodium berghei ANKA infected red blood cells using primary cell cultures derived from newborn C57BL/6 mice. We observed a dynamic transfer of vesicles from the parasite to astrocytes within minutes of contact, and the phagocytosis of infected red blood cells by microglia. Differential gene expression studies using the Affymetrix GeneChip(r) microarray, and quantitative PCR analyses showed the increase in expression of the set of genes belonging to the immune response network in parasite activated astrocytes and microglia. Interestingly, expression of these genes was also significantly upregulated in brains of mice dying from CM compared with uninfected mice or infected mice that did not develop the neuropathology. Accumulation of parasite-derived vesicles within astrocytes, and the phagocytosis of infected red blood cells by microglia induced a subsequent increase in interferon gamma inducible protein 10 (IP10) in both the brain and plasma of infected mice at the onset of CM, confirming a role for this molecule in CM pathogenesis. Altogether, these observations point to a possible role for glial cells in the neuropathological processes leading to CM. GLIA 2016 GLIA 2017;65:75 92. PMID- 27696530 TI - Stimulation-induced transient changes in neuronal activity, blood flow and N acetylaspartate content in rat prefrontal cortex: a chemogenetic fMRS-BOLD study. AB - Brain activation studies in humans have shown the dynamic nature of neuronal N acetylaspartate (NAA) and N-acetylaspartylglutamate (NAAG) based on changes in their MRS signals in response to stimulation. These studies demonstrated that upon visual stimulation there was a focal increase in cerebral blood flow (CBF) and a decrease in NAA or in the total of NAA and NAAG signals in the visual cortex, and that these changes were reversed upon cessation of stimulation. In the present study we have developed an animal model in order to explore the relationships between brain stimulation, neuronal activity, CBF and NAA. We use "designer receptor exclusively activated by designer drugs" (DREADDs) technology for site-specific neural activation, a local field potential electrophysiological method for measurement of changes in the rate of neuronal activity, functional MRS for measurement of changes in NAA and a blood oxygenation level-dependent (BOLD) MR technique for evaluating changes in CBF. We show that stimulation of the rat prefrontal cortex using DREADDs results in the following: (i) an increase in level of neuronal activity; (ii) an increase in BOLD and (iii) a decrease in the NAA signal. These findings show for the first time the tightly coupled relationships between stimulation, neuron activity, CBF and NAA dynamics in brain, and also provide the first demonstration of the novel inverse stimulation NAA phenomenon in an animal model. PMID- 27696531 TI - Effect of narrow band ultraviolet B phototherapy as monotherapy or combination therapy for vitiligo: a meta-analysis. AB - BACKGROUND: The treatment of vitiligo is still one of the most difficult dermatological challenges, although there are many therapeutic options. Narrow band ultraviolet B (NB-UVB) phototherapy is considered to be a very important modality for generalized vitiligo. OBJECTIVE: The aim of this study was to explore whether a combination of NB-UVB and topical agents would be superior to NB-UVB alone for treating vitiligo. METHODS: We searched the electronic databases such as PUBMED, EMBASE, Cochrane Library, and Web of Science. The primary outcome was the proportion of >=50% repigmentation (a clinical significance), and secondary outcome was the proportion of >=75% repigmentation (an excellent response). RESULTS: Seven randomized controlled trials (RCTs) involving 240 patients (413 lesions) were included in this meta-analysis. The study showed no significant difference between NB-UVB combination therapy (NB-UVB and topical calcineurin inhibitor or vitamin D analogs) and NB-UVB monotherapy in the outcomes of >=50% repigmentation and >=75% repigmentation. However, lesions located on the face and neck had better results in >=50% repigmentation (RR = 1.40, 95% CI 1.08-1.81) and >=75% repigmentation (RR = 1.88, 95% CI 1.10-3.20) with NB-UVB and topical calcineurin inhibitor combination therapy vs. NB-UVB monotherapy. CONCLUSIONS: The meta-analysis suggested that adding neither topical calcineurin inhibitors nor topical vitamin-D3 analogs on NB-UVB can yield significantly superior outcomes than NB-UVB monotherapy for treatment of vitiligo. However, addition of topical calcineurin inhibitors to NB-UVB may increase treatment outcomes in vitiligo affecting face and neck.

AB - An extracellular esterase gene estK was identified in Pseudomonas putida mt-2 and overexpressed at high levels in Escherichia coli. The recombinant EstK enzyme was purified and characterized kinetically against p-nitrophenyl ester and other aryl alkyl ester substrates and found to be selective for hydrolysis of acetyl ester substrates with high activity for p-nitrophenyl acetate (kcat 5.5 Sec-1 , KM 285 uM). Recombinant EstK was found to catalyze deacetylation of acetylated beech xylan, indicating a possible in vivo function for this enzyme, and partial deacetylation of a synthetic polymer (poly(vinylacetate)). EstK was found to catalyze enantioselective hydrolysis of racemic 1-phenylethyl acetate, generating 1R-phenylethanol with an enantiomeric excess of 80.4%.

AB - Cocaine addicted men have low startle magnitude persisting during prolonged abstinence. Low startle rats show greater cocaine self-administration than high startle rats. Low startle may be a marker of a vulnerability to heightened cocaine-related behaviors in rats and similarly may be a marker of vulnerability to cocaine addiction in humans.

AB - Persons living in communities with limited resources are at heightened risk of posttraumatic stress (PTS) after disasters, especially if they were highly exposed. The support deterrence desistence model and the conservation of resources theory suggest that this risk might increase in the longer-term aftermath of disasters. In the present study, we aimed to test this hypothesis. Two population-based samples of New York City residents in communities affected by Hurricane Sandy were surveyed at either 13-16 months (Time 1; n = 421) or 25 28 months (Time 2; n = 420) postdisaster. Participants reported on their exposure to disaster-related stressors and PTS. The percentage of residents who were unemployed in participants' census tracts was collected from the 2008-2012 American Community Survey. Multilevel models found that disaster-related stressors were more strongly associated with PTS for participants living in communities with high unemployment, but only at Time 2 (Est. = .58, SE = .21, p = .006). Mapping of community unemployment and disaster-related stressors suggested that communities in southern Brooklyn and Queens, and northeastern Staten Island were at particularly high risk for PTS at Time 2. The results suggest the need for ongoing support to economically disadvantaged communities in which residents have endured disaster-related stressors. PMID- 27696536 TI - The putative Walker A and Walker B motifs of Rrp2 are required for the growth of Borrelia burgdorferi. AB - Rrp2 encodes a putative bacterial enhancer binding protein (bEBP) in Borrelia burgdorferi. Point mutation (G239C) of Rrp2 abolishes the transcriptional activation of sigma54 -dependent rpoS. In contrast to canonical bEBPs that are dispensable for bacterial growth, Rrp2 is essential for borrelial growth in BSK medium. It has been believed that Rrp2's ATPase activity is not required for cell growth, but experimental evidence supporting this notion has been lacking. In particular, it has remained unclear whether the residue G239 is involved in Rrp2's presumptive ATPase activity. To address these information gaps, we examined the roles of Rrp2's potential strategic signatures including the G239 residue and the putative Walker A and Walker B motifs. Herein it was showed that Rrp2 has ATP binding and hydrolysis activities engendered by the Walker A and B motifs respectively. However, these activities were not significantly impaired by a G239C mutation. Further mutagenesis analyses indicated that Rrp2's Walker A and B motifs are required for borrelial growth; mutations of key residues in these two motifs were lethal to B. burgdorferi. The combined data suggest that the Walker A and Walker B motifs of Rrp2 are involved in the control of another unknown RpoS-independent gene product(s) associated with borrelial replication.

AB - Esophageal adenocarcinoma (EAC) is characterized by rapidly increasing incidence and mortality rates and poor survival. Efficacious preventive and treatment options are urgently needed. An increasing number of pharmacologic agents targeting cancer cell death via autophagy mechanisms are being evaluated in hopes of circumventing apoptotic and therapeutic resistance. We report for the first time, loss of Beclin-1, a key mediator of autophagy, was significantly linked to prognostic factors in EAC. Specifically, Beclin-1 expression loss occurred in 49.0% of EAC patients versus 4.8% of controls. There was a significant inverse correlation between loss of Beclin-1 with histologic grade and tumor stage supporting a tumor suppressive role for Beclin-1. Autophagy modulation linked to cell death was examined in EAC cell lines following treatment with a proanthocyanidin-rich cranberry extract, C-PAC, and the commonly used autophagy inducer, rapamycin. C-PAC induced Beclin-1-independent autophagy in EAC cells characterized by reduced phosphorylation at serine 15 and 93, and significant cell death induction. In contrast, rapamycin-induced autophagy resulted in concomitant, increases in total Beclin-1 levels as well as Beclin-1 phosphorylation in a cell line specific manner, leading to long-term cell survival. Furthermore, autophagic LC3-II was induced by C-PAC following siRNA suppression of Beclin-1 in EAC cells. Together these data support a prognostic role of Beclin-1 in EAC with evidence that Beclin-dependent autophagy induction is agent specific. Future studies are necessary to fully interrogate the role autophagy plays in the progression of normal tissue to EAC and how specific agents targeting autophagic mechanisms can be efficaciously applied for cancer prevention or treatment.

AB - Aberrant methylation of DNA is a common event in the development of cancers, including squamous cell carcinoma (SCC) of the human esophagus. In the present study, we determined: (a) whether aberrant DNA methylation also occurs in the development of N-nitrosomethylbenzylamine (NMBA)-induced tumorigenesis in the rat esophagus, a model of human esophageal SCC; and (b) if so, whether dietary black raspberries (BRBs) are capable of preventing this aberrant DNA methylation. A diet containing 5% BRBs inhibited the development of NMBA-induced tumors in the rat esophagus. This inhibition was associated with reduced mRNA levels of the DNA methyltransferases, Dnmt1 and Dnmt3b, in both dysplastic lesions and in papillomas of the esophagus. In addition, promoter methylation of Sfrp4, a WNT pathway antagonist, was significantly reduced by the berry diet, and this was associated with decreased nuclear localization of beta-CATENIN and reduced expression of c-MYC protein in NMBA-treated esophagi. Decreased promoter methylation of Sfrp4 correlated with decreased expression of Dmnt3b and, ultimately, with increased Sfrp4 mRNA expression. This suggests that epigenetic alterations in NMBA-induced rat esophageal tumorigenesis recapitulate epigenetic events in human esophageal SCC, and that BRBs could be useful in preventing the aberrant DNA methylation involved in the development of human esophageal SCC.

PMID- 27696540 TI - Humanistic and economic outcomes of pharmacist-provided medication review in the community-dwelling elderly: A systematic review and meta-analysis. AB - WHAT IS KNOWN AND OBJECTIVE: Recent reviews have shown that pharmacist-provided medication review in the elderly can improve clinical outcomes and reduce medication discrepancies compared with usual care. However, none determined whether these translate to improved humanistic and economic outcomes. This review sought to evaluate the effects of medication review on health-related quality of life (HRQoL) and healthcare costs in the elderly. METHODS: A systematic search of MEDLINE, EMBASE, CINAHL, Web of Science and the Cochrane library for studies published in English from inception to 31 August 2015 was conducted. The review included studies lasting at least 3 months that randomly assigned community dwelling participants aged at least 65 years to receive either pharmacist provided medication review or usual care. Studies set in nursing homes were excluded. RESULTS AND DISCUSSION: The review identified 25 studies that included 15 341 participants and lasted between 3 and 36 months. Twenty and 13 studies reported HRQoL and economic outcomes, respectively. Overall, there was no significant difference in HRQoL and healthcare costs between pharmacist-provided medication review and usual care. Meta-analysis of studies that reported the 36 item Short-Form Health Survey found significant differences in favour of usual care in the body pain (mean difference: 2.94, 95% CI: 0.54-5.34, P = 0.02) and general health perception (mean difference: 1.83, 95% CI: 0.16-3.50, P = 0.03) domains, whereas there were no significant differences in other domains. Meta analysis of the EuroQol-5D utility (mean difference: -0.01, 95% CI: -0.02-0.01, P = 0.57) and visual analogue scale (mean difference: 0.01, 95% CI: -3.24-3.26, P = 1.00) found no significant differences. Costs of hospitalization, medication and other healthcare resources consumed were similar between groups. WHAT IS NEW AND CONCLUSION: Humanistic and economic outcomes of pharmacist-provided medication review were largely similar to those of usual care. Further research using more robust methodology is needed to determine whether improved medication management can improve HRQoL and reduce healthcare costs. Careful thought should be given to capturing relevant outcomes that reflect the potential benefits of this intervention. PMID- 27696539 TI - Interlaboratory validation of organism recovery for use in 42-day sediment toxicity tests with Hyalella azteca. AB - Environment and Climate Change Canada has developed a 42-d sediment toxicity test that includes a reproduction endpoint with the freshwater amphipod Hyalella azteca. The new methodology conducts the entire exposure in sediment, in contrast to existing standardized methods whereby adults are transferred to a water-only exposure before release of their first brood at day 28. This midtest transfer to clean water was because of the results of a juvenile H. azteca recovery trial conducted in the 1990s concluding that reproductive endpoints could be biased because of low recovery of young amphipods from sediment. Using a new procedure and reduced volume of sediment, an interlaboratory recovery trial was conducted using 2-d to 5-d old H. azteca added to control sediment. A total of 29 technicians from 8 laboratories participated in the present study. The average recovery for all laboratories and all technicians was 76% (coefficient of variation [CV] = 30%). Based on an initial target recovery of at least 80%, 19 of 29 (66%) technicians met this criterion, with an average recovery for this group of 88% (CV = 8.3%). Factors that reduced recovery success included: not using a light table, technicians with minimal sediment testing experience, and the use of imported young amphipods with limited acclimation. Excluding those results, the overall average recovery, which included 17 participating technicians, increased from 76% to 88% and lowered the CV from 30% to 8.6%. Based on these results, Environment and Climate Change Canada will recommend >=85% average recovery of young in control sediment and require >=80% as a technician performance criterion in its new test design for the reproduction methodology.

PMID- 27696541 TI - Factors promoting resident deaths at aged care facilities in Japan: a review. AB - Due to an increasingly ageing population, the Japanese government has promoted elderly deaths in aged care facilities. However, existing facilities were not designed to provide resident end-of-life care and the proportion of aged care facility deaths is currently less than 10%. Consequently, the present review evaluated the factors that promote aged care facility resident deaths in Japan from individual- and facility-level perspectives to exploring factors associated with increased resident deaths. To achieve this, MEDLINE, CINAHL, Web of Science and Ichushi databases were searched on 23 January 2016. Influential factors were reviewed for two healthcare services (insourcing and outsourcing facilities) as well as external healthcare agencies operating outside facilities. Of the original 2324 studies retrieved, 42 were included in analysis. Of these studies, five focused on insourcing, two on outsourcing, seven on external agencies and observed facility/agency-level factors. The other 28 studies identified individual-level factors related to death in aged care facilities. The present review found that at both facility and individual levels, in-facility resident deaths were associated with healthcare service provision, confirmation of resident/family end-of-life care preference and staff education. Additionally, while outsourcing facilities did not require employment of physicians/nursing staff to accommodate resident death, these facilities required visits by physicians and nursing staff from external healthcare agencies as well as residents' healthcare input. This review also found few studies examining outsourcing facilities. The number of healthcare outsourcing facilities is rapidly increasing as a result of the Japanese government's new tax incentives. Consequently, there may be an increase in elderly deaths in outsourcing healthcare facilities. Accordingly, it is necessary to identify the factors associated with residents' deaths at outsourcing facilities.

AB - Data on sleep quality in renal transplanted (RTX) patients are scarce, and longitudinal studies are lacking. The purpose of this study was to assess the prevalence of sleep complaints in RTX patients and identify variables associated with improvement in sleep quality. In a longitudinal study, 301 dialysis patients were followed for up to 5.5 years, during which time 142 were transplanted. Out of the transplanted patients, a total of 110 were eligible for inclusion. Sleep quality and depression were assessed with the validated questionnaires Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Inventory (BDI), and data were collected during dialysis and after RTX. Based on PSQI scores, 59% were characterized as poor sleepers after RTX compared to 75% when in dialysis (P = 0.016). A total of 46% experienced a clinical relevant improvement in overall sleep quality, while 21% experienced a clinical relevant deterioration. In multivariable analyses, clinical meaningful change in sleep quality was not associated with either depressive symptoms assessed with BDI or other clinical variables. Sleep quality improved after RTX in nearly half of the patients, but poor sleep quality was prevalent in RTX patients. Therefore, sleep quality should routinely be assessed in RTX patients. PMID- 27696544 TI - The Learning Curve for Transcatheter Mitral Valve Repair With MitraClip. AB - OBJECTIVES: This study sought to assess the learning curve for TMVR for treatment of primary mitral regurgitation (MR). BACKGROUND: Data are lacking regarding the technical experience required to achieve optimal clinical outcomes with transcatheter mitral valve repair (TMVR) using the edge-to-edge MitraClip technique. METHODS: We examined the sequential experience of the first 75 patients (age 80 +/- 9 years; 77% male) who underwent TMVR at our institution. A sequence number of each patient was assigned as a continuous variable and in tertiles for analysis. RESULTS: TMVR with MitraClip was successful in 97% with an average procedural time of 106 +/- 39 minutes. The 30-day rate of major adverse cardiovascular events was 7%. With increased case experience, there were decreases in procedural time, fluoroscopy time, length of hospital stay, and major adverse cardiovascular events. Procedural success, residual mitral regurgitation and NYHA functional classification at 30-day follow-up remained unchanged throughout the experience. CONCLUSIONS: The learning curve for TMVR with MitraClip for treatment of primary MR is characterized by a sequential reduction in procedure time, fluoroscopy time, procedural complications, and hospital length of stay at a tertiary academic medical center. Thirty-day procedural results are favorable and similar during the initial learning period. PMID- 27696545 TI - Drug-Coated Balloons: Seeking a Niche in the Treatment of Coronary Artery Disease.

AB - The mechanism of the interaction between bovine serum albumin (BSA) and desvenlafaxine was studied using fluorescence, ultraviolet absorption, 3 dimensional fluorescence spectroscopy, circular dichroism, synchronous fluorescence spectroscopy, cyclic voltametry, differential scanning calorimetry, and attenuated total reflection-Fourier transform infrared spectroscopic techniques under physiological condition at pH 7.4. Stern-Volmer calculations authenticate the fluorescence of BSA that was quenched by desvenlafaxine in a collision quenching mode. The fluorescence quenching method was used to evaluate number of binding sites "n" and binding constant KA that were measured, and various thermodynamic parameters were evaluated at different temperatures by using the van't Hoff equation and differential scanning calorimetry technique, which indicated a spontaneous and hydrophobic interaction between BSA and desvenlafaxine. According to the Forster theory we calculate the distance between the donor, BSA and acceptor, desvenlafaxine molecules. Furthermore, circular dichroism and attenuated total reflection-Fourier transform infrared spectroscopy indicate nominal changes in the secondary structure of the protein. PMID- 27696549 TI - Using a choice experiment and birder preferences to guide bird-conservation funding. AB - Conservation of biodiversity, including birds, continues to challenge natural area managers. Stated-preference methods (e.g., choice experiment [CE]) are increasingly used to provide data for valuation of natural ecosystems. We used a CE to calculate birders' willingness to pay for different levels of bioecological attributes (threatened species, endemic species, and diversity) of birding sites with hypothetical entry fees. The CE was delivered at popular birding and avitourism sites in Australia and the United Kingdom. Latent-class modeling results revealed heterogeneous preferences among birders and correspondingly variable willingness to pay. Four clear groups were apparent: quantity-driven birders, special-birds seekers, confused respondents, and price-is-no-object birders. Quantity-driven birders were attracted to sites that deliver high levels of diversity and endemic species for which they were willing to pay $135 and $66 to visit, respectively, above what they were willing to pay to visit a site with low levels of diversity and few endemic and threatened species . Special-bird seekers valued threatened species and high levels of endemic species most (willingness to pay $45 and $46, respectively). Confused respondents' preferences were difficult to determine, but they were the most sensitive to the hypothetical entry fees, unlike the price-is-no-object birders, who were not at all sensitive to cost. Our findings demonstrate that birders are amenable to paying for their preferred birding experience. These payments could provide an alternative source of funding in some avitourism sites on both public and private land. Such alternative revenue streams should be explored and given full consideration in increasingly competitive conservation-financing environments. PMID- 27696550 TI - Effect of a repeated tongue-lift motor task for tongue function. AB - This study investigated the effect of repeated tongue motor tasks on suprahyoid muscle activity and tongue pressure. Fourteen participants performed three series of a standardized tongue-lift training (TLT) task on each of five consecutive days. Electromyographic (EMG) activity from suprahyoid muscles and tongue pressure were recorded. In the first and third TLT series, participants were instructed only to target different force levels. During the second TLT series, visual feedback of the force level was given. One series consisted of three measurements [at 10%, 20%, and 40% of maximum voluntary contraction (MVC), respectively]. The coefficient of determination of the target force level-EMG curve and the target force level-tongue pressure curve was calculated from all series. There were no statistically significant day-to-day differences in EMG root mean square (RMS) values and tongue pressure during MVC. The coefficients of determination of tongue pressure in the first series on day 1 were statistically significantly lower than the coefficients of determination in the first series on day 5. These findings suggest that the control of tongue pressure improved, while the maximum force remained constant. These results could have implications for treatment paradigms related to learning for patients with compromised tongue function, such as swallowing disorders or dysphagia. PMID- 27696551 TI - Pethidine hydrochloride is a better sedation method for pharyngeal observation by transoral endoscopy compared with no sedation and midazolam. AB - BACKGROUND AND AIM: Standard surveillance methods for pharyngeal cancer have not been established. We conducted a randomized controlled trial to investigate the best sedation method for pharyngeal observation using transoral endoscopy. METHODS: In total, 120 patients who underwent surveillance or diagnostic examinations for esophageal cancer were enrolled and divided equally into three groups (no sedation, midazolam, or pethidine hydrochloride). In the midazolam group, midazolam was given i.v. maintaining a Ramsay score of 3. In the pethidine group, pethidine hydrochloride (35 mg) given i.v. Seven sites in five pharyngeal regions were observed on insertion of the endoscope, and graded (0 = poor, 1 = good). After examination, the five pharyngeal regions were scored using a seven point scale. Primary endpoint was the total score from the five pharyngeal regions. Secondary endpoints were the proportion of the perfect score using the seven-point scale, discomfort score, and adverse events. RESULTS: Mean total scores for the no sedation group, the midazolam group and the pethidine group were 5.7, 5.5, and 6.8, respectively (P < 0.0001). Proportion of patients with a perfect score for the no sedation group, the midazolam group and the pethidine group were 53%, 35%, and 89%, respectively (P < 0.0001). The pethidine group had better results than the other two groups. Discomfort score and adverse events were low in the pethidine group. CONCLUSION: Pethidine hydrochloride is a feasible and safe sedation method, and was superior to no sedation and midazolam regarding pharyngeal observation of esophageal cancer patients.

PMID- 27696553 TI - Developmental regulation and modulation of apoptotic genes expression in sheep oocytes and embryos cultured in vitro with L-carnitine. AB - The objective of this study was to find out the impact of L-carnitine (10 mM) on developmental regulation of preimplantation sheep embryos cultured in vitro when supplemented in maturation medium and post-fertilization medium separately. Subsequent objective was to observe the L-carnitine-mediated alteration in expression of apoptotic genes (Bcl2, Bax, Casp3 and PCNA) in sheep oocytes and developing embryos produced in vitro. Oocytes matured with L-carnitine showed significantly (p < .05) higher cleavage (67.23% vs 43.12%), morula (47.65% vs 28.58%) and blastocysts (32.12% vs 13.24%) percentage as compared to presumptive zygotes cultured with L-carnitine during post-fertilization period. So it is suggested to use L-carnitine during maturation than post-fertilization period. Antiapoptotic and proliferative effects of L-carnitine were confirmed by inducing culture medium with actinomycin D (apoptotic agent) and TNFalpha (antiproliferative agent), respectively, with and without L-carnitine. Oocytes and embryos cultured with actinomycin D and TNFalpha showed developmental arrest with significant (p < .05) decrease in morula and blastocysts percentage but supplementation of L-carnitine to actinomycin D and TNFalpha induced culture medium showed similar result as that of control. L-carnitine supplementation during IVM significantly (p < .05) upregulated the expression of Bcl2 and PCNA genes in majority of the developmental stages. Although L-carnitine upregulated the expression of Bax in initial developmental stages but downregulated at latter part, whereas the expression of Casp3 was upregulated upto 16-cell stage but after that there was no difference in expression. Expression of GAPDH gene was not affected by L-carnitine supplementation. In conclusion, L-carnitine acted as an antiapoptotic and proliferative compound during embryo development and supplementation of L-carnitine during IVM altered the expression of apoptotic genes in the developmental stages of embryos. PMID- 27696554 TI - Evaluation of Staphylococcus aureus DNA aptamer by enzyme-linked aptamer assay and isothermal titration calorimetry. AB - To monitor the specificity of Staphylococcus aureus aptamer (SA-31) against its target cell, we used enzyme-linked aptamer assay. In the presence of target cell, horseradish peroxidase-conjugated streptavidin bound to biotin-labeled SA-31 showed specific binding to S aureus among 3 different bacteria with limit of detection of 103 colony-forming unit per milliliter. The apparent Ka was 1.39 MUM 1 +/- 0.3 MUM-1 . The binding of SA-31 to membrane proteins extracted from cell surface was characterized using isothermal titration calorimetry, and the effect of changes in binding temperature and salt concentrations of binding buffer was evaluated based on thermodynamic parameters (Ka , DeltaH, and DeltaG). Since binding of aptamer to its targets solely depends on its 3-dimensional structure under experimental conditions used in selection process, the change in temperature and ion concentration changed the affinity of SA-31 to its target on surface of bacteria. At 4 degrees C, SA-31 did not show an affinity to its target with poor heat change upon injection of membrane fraction to aptamer solution. However, the apparent association constants of SA-31 slightly varied from Ka = 1.56 MUM-1 +/- 0.69 MUM-1 at 25 degrees C to Ka = 1.03 MUM-1 +/- 0.9 MUM-1 at 37 degrees C. At spontaneously occurring exothermic binding reactions, affinities of S aureus aptamer to its target were also 9.44 MUM-1 +/- 0.38 MUM-1 at 50mM, 1.60 MUM-1 +/- 0.11 MUM-1 at 137mM, and 3.28 MUM-1 +/- 0.46 MUM-1 at 200 mM of salt concentration. In this study, it was demonstrated that enzyme-linked aptamer assay and isothermal titration calorimetry were useful tools for studying the fundamental binding mechanism between a DNA aptamer and its target on the outer surface of S aureus. PMID- 27696555 TI - Relationship between mechanical properties and bond durability of short fiber reinforced resin composite with universal adhesive. AB - The purpose of this study was to determine the relationship between mechanical properties and bond durability of short fiber-reinforced resin composite with universal adhesive. As controls, micro-hybrid and nano-hybrid resin composites were tested. The universal adhesives used were Scotchbond Universal, Adhese Universal, and G-Premio Bond. The fracture toughness and flexural properties of resin composites, and shear bond strength and shear fatigue strength of universal adhesive with resin composite using both total-etch and self-etch modes were determined. In the results, short fiber-reinforced resin composite showed significantly higher fracture toughness than did micro-hybrid and nano-hybrid resin composites. The flexural strength and modulus of short fiber-reinforced and nano-hybrid resin composites were significantly lower than were those of micro hybrid resin composites. Regardless of etching mode, the shear bond strength of universal adhesives with short fiber-reinforced resin composite did not show any significant differences from micro-hybrid and nano-hybrid resin composites. The shear fatigue strength of universal adhesives with short fiber-reinforced resin composite and micro-hybrid resin composites were significantly higher than that of nano-hybrid resin composites. The results of this study suggest that the mechanical properties of short fiber-reinforced resin composite improve their bond durability with universal adhesive. PMID- 27696557 TI - Changing epidemiology of oral squamous cell carcinoma of the tongue: A global study. AB - BACKGROUND: There are reports about the changing epidemiology of tongue squamous cell carcinoma (SCC), with recent reports indicating an increasing incidence in young women. METHODS: Data on incident cases of tongue SCC were collected from cancer registries worldwide. RESULTS: Data from a total of 22 cancer registries and 89,212 incident cases of tongue SCC worldwide were included. Most areas experienced an incidence increase ranging from 0.4% to 3.3% per year. There was a significant difference in the incidence increase between sexes in 11 of the 22 registries. In 14 of the 22 registries studied, the increase in incidence of tongue SCC was higher in the group of subjects <45 years old than those >=45 years old. CONCLUSION: This study suggests a general but not universal increase in the incidence of tongue SCC worldwide. In some regions of the world, we observed a shifting trend toward women and/or younger patients. (c) 2016 Wiley Periodicals, Inc. Head Neck 39: 297-304, 2017. PMID- 27696559 TI - Toward reassessing data-deficient species. AB - One in 6 species (13,465 species) on the International Union for Conservation of Nature (IUCN) Red List is classified as data deficient due to lack of information on their taxonomy, population status, or impact of threats. Despite the chance that many are at high risk of extinction, data-deficient species are typically excluded from global and local conservation priorities, as well as funding schemes. The number of data-deficient species will greatly increase as the IUCN Red List becomes more inclusive of poorly known and speciose groups. A strategic approach is urgently needed to enhance the conservation value of data-deficient assessments. To develop this, we reviewed 2879 data-deficient assessments in 6 animal groups and identified 8 main justifications for assigning data-deficient status (type series, few records, old records, uncertain provenance, uncertain population status or distribution, uncertain threats, taxonomic uncertainty, and new species). Assigning a consistent set of justification tags (i.e., consistent assignment to assessment justifications) to species classified as data deficient is a simple way to achieve more strategic assessments. Such tags would clarify the causes of data deficiency; facilitate the prediction of extinction risk; facilitate comparisons of data deficiency among taxonomic groups; and help prioritize species for reassessment. With renewed efforts, it could be straightforward to prevent thousands of data-deficient species slipping unnoticed toward extinction. PMID- 27696558 TI - Fast diffusion kurtosis imaging (DKI) with Inherent COrrelation-based Normalization (ICON) enhances automatic segmentation of heterogeneous diffusion MRI lesion in acute stroke. AB - Diffusion kurtosis imaging (DKI) has been shown to augment diffusion-weighted imaging (DWI) for the definition of irreversible ischemic injury. However, the complexity of cerebral structure/composition makes the kurtosis map heterogeneous, limiting the specificity of kurtosis hyperintensity to acute ischemia. We propose an Inherent COrrelation-based Normalization (ICON) analysis to suppress the intrinsic kurtosis heterogeneity for improved characterization of heterogeneous ischemic tissue injury. Fast DKI and relaxation measurements were performed on normal (n = 10) and stroke rats following middle cerebral artery occlusion (MCAO) (n = 20). We evaluated the correlations between mean kurtosis (MK), mean diffusivity (MD) and fractional anisotropy (FA) derived from the fast DKI sequence and relaxation rates R1 and R2 , and found a highly significant correlation between MK and R1 (p < 0.001). We showed that ICON analysis suppressed the intrinsic kurtosis heterogeneity in normal cerebral tissue, enabling automated tissue segmentation in an animal stroke model. We found significantly different kurtosis and diffusivity lesion volumes: 147 +/- 59 and 180 +/- 66 mm3 , respectively (p = 0.003, paired t-test). The ratio of kurtosis to diffusivity lesion volume was 84% +/- 19% (p < 0.001, one-sample t-test). We found that relaxation-normalized MK (RNMK), but not MD, values were significantly different between kurtosis and diffusivity lesions (p < 0.001, analysis of variance). Our study showed that fast DKI with ICON analysis provides a promising means of demarcation of heterogeneous DWI stroke lesions. PMID- 27696560 TI - Functional characterization of UDP-rhamnose-dependent rhamnosyltransferase involved in anthocyanin modification, a key enzyme determining blue coloration in Lobelia erinus. AB - Because structural modifications of flavonoids are closely related to their properties, such as stability, solubility, flavor and coloration, characterizing the enzymes that catalyze the modification reactions can be useful for engineering agriculturally beneficial traits of flavonoids. In this work, we examined the enzymes involved in the modification pathway of highly glycosylated and acylated anthocyanins that accumulate in Lobelia erinus. Cultivar Aqua Blue (AB) of L. erinus is blue-flowered and accumulates delphinidin 3-O-p coumaroylrutinoside-5-O-malonylglucoside-3'5'-O-dihydroxycinnamoylglucoside (lobelinins) in its petals. Cultivar Aqua Lavender (AL) is mauve-flowered, and LC MS analyses showed that AL accumulated delphinidin 3-O-glucoside (Dp3G), which was not further modified toward lobelinins. A crude protein assay showed that modification processes of lobelinin were carried out in a specific order, and there was no difference between AB and AL in modification reactions after rhamnosylation of Dp3G, indicating that the lack of highly modified anthocyanins in AL resulted from a single mutation of rhamnosyltransferase catalyzing the rhamnosylation of Dp3G. We cloned rhamnosyltransferase genes (RTs) from AB and confirmed their UDP-rhamnose-dependent rhamnosyltransferase activities on Dp3G using recombinant proteins. In contrast, the RT gene in AL had a 5-bp nucleotide deletion, resulting in a truncated polypeptide without the plant secondary product glycosyltransferase box. In a complementation test, AL that was transformed with the RT gene from AB produced blue flowers. These results suggest that rhamnosylation is an essential process for lobelinin synthesis, and thus the expression of RT has a great impact on the flower color and is necessary for the blue color of Lobelia flowers. PMID- 27696561 TI - Evaluation of the Relationship Between Microalbuminuria and Urine Ischemia Modified Albumin Levels in Patients with Diabetic Nephropathy. AB - INTRODUCTION: Ischemia-modified albumin (IMA) is a marker which can be associated with oxidative stress in various ischemic and non-ischemic processes. Oxidative stress plays roles in diabetes mellitus, its complications and pathogenesis. Serum IMA levels are examined in various clinical events. However, urine IMA levels have not yet been evaluated in diabetic patients. In this study, we aim to examine the relationship between metabolic features and urine microalbuminuria levels of diabetic patients and their urine IMA levels. MATERIALS AND METHODS: There were totally 50 type 2 diabetic patients in the study at the Mevlana University Hospital. Patients with cerebrovascular disease, acute myocardial infarction, hemodialysis patients with end stage chronic renal failure, pulmonary embolism, and malignant disease were excluded from the study. Metabolic features, urine IMA levels and cardiological parameters of patients were evaluated. RESULTS: Mean age of patients was 59 +/- 9 years, 20 of them (40%) were male and 30 of them (60%) were female. There were six patients with albuminuria value of <0.03 mg/g (normal), there were 39 patients with microalbuminuria value of 0.03 0.3 mg/g and there were five patients with macroalbuminuria of >0.3 mg/g. According to the analysis of patients with microalbuminuria (n = 39), there was no correlation between IMA levels and numerical demographic data, albuminuria, glucose, HbA1c, lipid profile, creatinine, uric acid, hematological parameters. DISCUSSION: Conclusively, there was no relationship between urine IMA levels and microalbuminuria related to the diabetic nephropathy. These findings can be associated with urinary excretion mechanisms of IMA. PMID- 27696562 TI - Combined antifungal therapy against systemic murine infections by rare Cryptococcus species. AB - Cryptococcus albidus and Cryptococcus laurentii are uncommon species of this genus that in recent decades have increasingly caused opportunistic infections in humans, mainly in immunocompromised patients; the best therapy for such infection being unknown. Using a murine model of systemic infection by these fungi, we have evaluated the efficacy of amphotericin B (AMB) at 0.8 mg/kg, administered intravenously, fluconazole (FLC) or voriconazole (VRC), both administered orally, at 25 mg/kg and the combination of AMB plus VRC against three C. albidus and two C. laurentii strains. All the treatments significantly reduced the fungal burden in all the organs studied. The combination showed a synergistic effect in the reduction in fungal load, working better than both monotherapies. The histopathological study confirmed the efficacy of the treatments. PMID- 27696563 TI - Antennal and mouthpart sensilla of Acanthoscelides obtectus say (Coleoptera: Bruchidae). AB - Acanthoscelides obtectus, a serious pest with a worldwide distribution, damages stored seeds of Phaseolus sp. To acquire a better understanding of the sensory orientation of bean weevils, their antennal and palpal sensilla were investigated. The antennae and palps possess several types of sensory hairs: blunt-tipped sensilla chaetica and trichoidea and also sharp-tipped sensilla trichoidea, these last being the most numerous. Sensilla basiconica are present only on the flagellomeres, but Bohm bristles occur on the basal sclerite and scape of the antennae. The terminal segments of the maxillary and labial palps bear a group of sensilla styloconica with single apical pores. Sensilla coeloconica are located only on the terminal palpal segments. They were unable to detect any distinct morphological differences between males and females. The possible chemosensory, mechanosensory, and thermo-/hygroreceptive functions of the sensilla are discussed. PMID- 27696565 TI - Cerebral blood flow laterality derived from arterial spin labeling as a biomarker for assessing the disease severity of parkinson's disease. AB - PURPOSE: To evaluate cerebral blood flow (CBF) laterality derived from arterial spin labeling (ASL) in early-stage Parkinson's disease (PD) patients compared with those with advanced stages. MATERIALS AND METHODS: Thirty-eight patients with PD (21 patients in early stages, 17 patients in advanced stages) were retrospectively studied. The CBF maps derived from 3T ASL data were co-registered to the corresponding 3DT1WI using SPM 12 software. Caudate nucleus (CN), putamen (PT), globus pallidus (GP), and thalamus (TH) were manually traced on the representative axial slices of 3DT1WI. CBF of the CN, PT, GP, and TH was measured using corresponding pixels on the co-registered CBF maps. A laterality index (LI) was calculated as the ratio of the contralateral CBF to primary affected side CBF. Each LI was compared between early and advanced stages of PD using the Mann Whitney U-test. The LIs were also compared between each stage of PD. RESULTS: In the CN, the LIs were significantly higher in early stages (mean LI +/- SD, 95% confidence interval = 1.06 +/- 0.14, 1.00-1.13) than in advanced stages (0.94 +/- 0.14, 0.87-1.01; P < 0.05). We also observed a tendency toward decreased LIs with disease severity (1.10 +/- 0.14, 0.99-1.21 for Hoehn and Yahr stage I; 1.04 +/- 0.14, 0.92-1.12 for stage II; 0.96 +/- 0.11, 0.89-1.10 for stage III; 0.93 +/- 0.17, 0.81-1.05 for stage IV). CONCLUSION: The evaluation of CBF laterality pattern in the CN using ASL may be useful for assessing the disease severity of PD patients. LEVEL OF EVIDENCE: 3 J. MAGN. RESON. IMAGING 2017;45:1821-1826. PMID- 27696564 TI - A novel glycan modifies the flagellar filament proteins of the oral bacterium Treponema denticola. AB - While protein glycosylation has been reported in several spirochetes including the syphilis bacterium Treponema pallidum and Lyme disease pathogen Borrelia burgdorferi, the pertinent glycan structures and their roles remain uncharacterized. Herein, a novel glycan with an unusual chemical composition and structure in the oral spirochete Treponema denticola, a keystone pathogen of periodontitis was reported. The identified glycan of mass 450.2 Da is composed of a monoacetylated nonulosonic acid (Non) with a novel extended N7 acyl modification, a 2-methoxy-4,5,6-trihydroxy-hexanoyl residue in which the Non has a pseudaminic acid configuration (L-glycero-L-manno) and is beta-linked to serine or threonine residues. This novel glycan modifies the flagellin proteins (FlaBs) of T. denticola by O-linkage at multiple sites near the D1 domain, a highly conserved region of bacterial flagellins that interact with Toll-like receptor 5. Furthermore, mutagenesis studies demonstrate that the glycosylation plays an essential role in the flagellar assembly and motility of T. denticola. To our knowledge, this novel glycan and its unique modification sites have not been reported previously in any bacteria. PMID- 27696566 TI - Generation of RUNX3 knockout pigs using CRISPR/Cas9-mediated gene targeting. AB - Pigs are an attractive animal model to study the progression of cancer because of their anatomical and physiological similarities to human. However, the use of pig models for cancer research has been limited by availability of genetically engineered pigs which can recapitulate human cancer progression. Utilizing genome editing technologies such as CRISPR/Cas9 system allows us to generate genetically engineered pigs at a higher efficiency. In this study, specific CRISPR/Cas9 systems were used to target RUNX3, a known tumour suppressor gene, to generate a pig model that can induce gastric cancer in human. First, RUNX3 knockout cell lines carrying genetic modification (monoallelic or biallelic) of RUNX3 were generated by introducing engineered CRISPR/Cas9 system specific to RUNX3 into foetal fibroblast cells. Then, the genetically modified foetal fibroblast cells were used as donor cells for somatic cell nuclear transfer, followed by embryo transfer. We successfully obtained four live RUNX3 knockout piglets from two surrogates. The piglets showed the lack of RUNX3 protein in their internal organ system. Our results demonstrate that the CRISPR/Cas9 system is effective in inducing mutations on a specific locus of genome and the RUNX3 knockout pigs can be useful resources for human cancer research and to develop novel cancer therapies. PMID- 27696567 TI - Phenotype and influx kinetics of leukocytes and inflammatory cytokine production in kidney ischemia/reperfusion injury. AB - BACKGROUND AND AIM: Kidney ischemia/reperfusion (IR) injury is characterized by tubular epithelial cell (TEC) death and an inflammatory response involving cytokine production and immune cell infiltration. In various kidney diseases, increased macrophage numbers correlate with injury severity and poor prognosis. However, macrophage plasticity enables a diverse range of functions, including wound healing, making them a key target for novel therapies. This study aimed to comprehensively characterize the changes in myeloid and epithelial cells and the production of cytokines throughout the experimental IR model of acute kidney injury to aid in the identification of targets to promote and enhance kidney regeneration and repair. METHODS: Flow cytometric analysis of murine unilateral IR injury was used to assess TEC and myeloid cell subpopulations in conjunction with histological analysis and cytokine production at 6 h, 1, 3, 5 and 7 days post IR injury, spanning the initial inflammatory phase and the following reparative phase. RESULTS: IR injury resulted in a rapid infiltration of Ly6Chigh monocytes and neutrophils with a steady rise in F4/80high MHCIIhigh macrophages over the injury time. The production of the inflammatory cytokines IL-6, MCP-1 and TNF coincided with an increase in IL-10 production. CONCLUSION: This characterization will provide a reference point for future studies designed to manipulate immune cell phenotype and function in order to promote endogenous repair of damaged kidneys. PMID- 27696568 TI - Postural orthostatic tachycardia is not a useful diagnostic marker for chronic fatigue syndrome. AB - BACKGROUND: Postural orthostatic tachycardia syndrome (POTS) is considered a diagnostic marker for chronic fatigue syndrome (CFS). OBJECTIVES: The aims of this study were to (i) compare POTS prevalence in a CFS cohort with fatigued patients not meeting CFS criteria, and (ii) assess activity, impairment and response to cognitive behavioural therapy (CBT) in CFS patients with POTS (POTS CFS) and without POTS (non-POTS-CFS). METHODS: Prospective cohort study at the Radboud University Medical Centre in the Netherlands. Between June 2013 and December 2014, 863 consecutive patients with persistent fatigue were screened. Patients underwent an active standing test, filled out questionnaires and wore an activity-sensing device for a period of 12 days. RESULTS: A total of 419 patients with CFS and 341 non-CFS fatigued patients were included in the study. POTS prevalence in adult patients with CFS was 5.7% vs. 6.9% in non-CFS adults (P = 0.54). In adolescents, prevalence rates were 18.2% and 17.4%, respectively (P = 0.93). Adult patients with POTS-CFS were younger (30 +/- 12 vs. 40 +/- 13 years, P = 0.001) and had a higher supine heart rate (71 +/- 11 vs. 65 +/- 9 beats per min, P = 0.009) compared with non-POTS-CFS patients. Severity and activity patterns did not differ between groups. In patients with CFS, criteria for Systemic Exertion Intolerance Disease (SEID) were met in 76% of adults and 67% of adolescents. In these patients with CFS fulfilling the SEID criteria, the prevalence of POTS was not different from that in the overall CFS population. POTS-CFS adolescents had less clinically significant improvement after CBT than non-POTS-CFS adolescents (58% vs. 88%, P = 0.017). CONCLUSION: In adults with CFS, the prevalence of POTS was low, was not different from the rate in non-CFS fatigued patients and was not related to disease severity or treatment outcome. In POTS-CFS adolescents, CBT was less successful than in non-POTS-CFS patients. The evaluation of POTS appears to be of limited value for the diagnosis of CFS.

PMID- 27696569 TI - Fixed-time post-cervical artificial insemination in weaned sows following buserelin use combined with/without eCG. AB - Fixed-time post-cervical artificial insemination (FTAI) drastically reduces labour requirements and increases the use of boars with higher genetic merit. This study evaluated the efficiency of eCG administration combined with/without the GnRH agonist buserelin for the induction and synchronization of ovulation in weaned sows submitted to FTAI. The sows were allocated into three groups. In the control group, the first artificial insemination was performed at the onset of oestrus and repeated every 24 hr. In the eCG+GnRH group, sows received 600 IU eCG at weaning and buserelin (10 MUg) after 86-89 hr of eCG, and in the GnRH group, sows received only buserelin after 86-89 hr of weaning. The hormone-treated sows received a single FTAI after 30-33 hr of buserelin application. All the sows were inseminated with homospermic doses (1.5 * 109 sperm cells/50 ml). The interval between weaning and ovulation was shorter (p < .05) in the eCG+GnRH (133.3 hr) and GnRH (135.9 hr) groups than the control (141.5 hr) group. In the eCG+GnRH group, the sows ovulated earlier (p < .05) than those in the GnRH group (44.5 vs. 48.2 hr after buserelin administration). The reproductive performance of GnRH sows was not compromised when only sows exhibiting oestrus at the time of insemination were considered, but lower farrowing rate and smaller litter size were observed in eCG+GnRH sows. The reproductive performance of eCG+GnRH sows was primarily compromised because the insemination was performed outside the optimal time relative to ovulation; therefore, it is advisable to inseminate them before 116-122 hr after weaning. PMID- 27696571 TI - Multilocus approaches for the measurement of selection on correlated genetic loci. AB - The study of ecological speciation is inherently linked to the study of selection. Methods for estimating phenotypic selection within a generation based on associations between trait values and fitness (e.g. survival) of individuals are established. These methods attempt to disentangle selection acting directly on a trait from indirect selection caused by correlations with other traits via multivariate statistical approaches (i.e. inference of selection gradients). The estimation of selection on genotypic or genomic variation could also benefit from disentangling direct and indirect selection on genetic loci. However, achieving this goal is difficult with genomic data because the number of potentially correlated genetic loci (p) is very large relative to the number of individuals sampled (n). In other words, the number of model parameters exceeds the number of observations (p ? n). We present simulations examining the utility of whole genome regression approaches (i.e. Bayesian sparse linear mixed models) for quantifying direct selection in cases where p ? n. Such models have been used for genome-wide association mapping and are common in artificial breeding. Our results show they hold promise for studies of natural selection in the wild and thus of ecological speciation. But we also demonstrate important limitations to the approach and discuss study designs required for more robust inferences. PMID- 27696572 TI - Distinct interferon-gamma and interleukin-9 expression in cutaneous and oral lichen planus. AB - BACKGROUND: Cutaneous (CLP) and oral lichen planus (OLP) as the main subtypes of lichen planus (LP) present with different clinical manifestation and disease course, although their histopathologic features such as the band-like lymphocyte infiltrate and keratinocyte apoptosis are similar. So far, the underlying cellular and molecular mechanisms remain poorly understood. OBJECTIVE: The aim of this study was to characterize and compare the in situ cellular infiltrates, cytokine expression profiles and apoptosis markers in CLP and OLP. METHODS: Using immunofluorescence staining and laser scanning microscopy, we evaluated the cellular infiltrate (CD1a, CD3, CD4, CD8, CD21, CD57, CD123), cytokine expression (interleukin (IL)-1, IL-6, IL-9, IL-10, IL-17, IL-22, IL-23, tumour necrosis factor-alpha, transforming growth factor-beta, interferon (IFN)-gamma), and apoptosis markers (Fas, Fas ligand, cleaved caspase-3, TUNEL) of 21 anonymized biopsy specimens of LP (11 CLP, 10 OLP). RESULTS: Among infiltrating cells mainly T cells and natural killer (NK) cells as well as plasmacytoid dendritic cells (DC) were observed. A predominance of CD8+ T cells was noted in OLP. In both CLP and OLP, T helper (Th)1, Th9, Th17, and Th22-type cytokines were expressed. The expression of IL-9, IFN-gamma and IL-22 was higher in CLP compared to that of OLP (P = 0.0165; P = 0.0016; P = 0.052 respectively). Expression of Fas and Fas ligand as well as cleaved caspase-3-positive cells was observed in the epithelium of all LP samples. CONCLUSIONS: The cell and cytokine patterns of CLP and OLP were partially distinct and generally resembled those reported for autoimmune diseases. The presence of CD8+ and NK cells as well as Fas/Fas ligand expression suggested that various pathways involved in keratinocyte apoptosis are relevant for LP. These results might help to establish targeted therapies for LP. PMID- 27696573 TI - Children referred for specialty care: Parental perspectives and preferences on referral, follow-up and primary care. AB - AIM: Over the last decade, there has been a dramatic increase in the number of referrals for paediatric subspecialty care and in overall appointments (new and review) to these doctors. We sought to determine the perspective of parents regarding their role in the initiation of referrals, their preferences for follow up and the role of general practitioners (GPs) in care co-ordination. METHODS: Self-completed survey in outpatient paediatric clinics (general paediatrics and four subspecialties) at two children's hospitals in Victoria. Recruitment targets were 100 parents in each of the general paediatrics clinics and 50 parents in each subspecialty clinic, equally divided between new and review visits (total n = 600). RESULTS: A total of 606 parents provided responses, with a decline rate of 9%. Many (52%) new patients were referred by a GP with the remainder from a variety of other sources. With specific regard to providing general care to their child, only 45% were completely confident in a GP. Most (76%) agreed with the statement that a GP would give their child a referral to see a paediatrician whenever they ask. Approximately, a third of parents reported that a GP rarely or never co-ordinates the care of their child with other doctors. CONCLUSIONS: Parents play an important role in both the initiation of paediatric specialty referrals and the patterns of follow-up care provided. Parent perspectives, preferences and motivations on both the referral process and the patterns for ongoing care are essential to develop policies that provide the best and most efficient care for children. PMID- 27696574 TI - Diaminodiphenylmethane Sensitization in north-eastern Italy from 1996 to 2012. AB - BACKGROUND: 4,4'-Diaminodiphenylmethane (DDM) is an aromatic amine used as a hardener, insulator and anticorrosive. Exposure implies risk of being sensitized and developing contact dermatitis. OBJECTIVE: The aim of this study was to determine the occurrence of contact sensitization to DDM among patients with contact dermatitis and the role of occupational exposure. PATIENTS AND METHODS: From 1996 to 2012, 24 056 consecutive patients with suspected allergic contact dermatitis were patch tested in north-eastern Italy. Individual characteristics were collected through a standardized questionnaire in eight departments of dermatology and occupational medicine. RESULTS: The overall prevalence of DDM sensitization was 2.5% (n = 599) with a decreasing trend in considered years. Trieste area had the higher prevalence of sensitization (3.2%). Mechanics and chemical industry workers had a significant higher risk of being sensitized to DDM. CONCLUSION: DDM sensitization is decreasing in years and is associated with some occupational exposures. PMID- 27696575 TI - Modulatory effects of vitamin D on peripheral cellular immunity in patients with recurrent miscarriage. AB - PROBLEM: We aimed to investigate the modulatory effects of vitamin D on peripheral blood cellular immune response in patients with recurrent miscarriage (RM). METHOD OF STUDY: The effect of vitamin D on the number of peripheral blood cells, T helper 1 (Th1) cytokines, and NK cytotoxicity was measured in 99 women with RM. RESULTS: The percentage of CD19+ B cells and NK cytotoxicity at an effector-to-target cell (E:T) ratio of 50:1, 25:1, and 12.5:1 were significantly higher in the vitamin D insufficiency group (VDI) than in the vitamin D normal group (VDN) (P<.05 each). The proportion of TNF-alpha-expressing Th cells was significantly higher in the vitamin D deficiency group (VDD) than in VDN (P<.05). However, there were no significant differences between VDI and VDD. This dysregulation was significantly reduced with 1,25(OH)2 D supplementation. CONCLUSION: The data suggest that the abnormalities of cellular immune response were observed in RM patients with a low vitamin D level, which could be regulated to some extent with 1,25(OH)2 D supplementation. PMID- 27696576 TI - Contrast-enhanced Digital Mammography: A Single-Institution Experience of the First 208 Cases. AB - Contrast-enhanced digital mammography (CEDM) is the only imaging modality that provides both (a) a high-resolution, low-energy image comparable to that of digital mammography and (b) a contrast-enhanced image similar to that of magnetic resonance imaging. We report the initial 208 CEDM examinations performed for various clinical indications and provide illustrative case examples. Given its success in recent studies and our experience of CEDM primarily as a diagnostic adjunct, CEDM can potentially improve breast cancer detection by combining the low-cost conclusions of screening mammography with the high sensitivity of magnetic resonance imaging. PMID- 27696577 TI - Treatment outcomes with ixekizumab in patients with moderate-to-severe psoriasis who have or have not received prior biological therapies: an integrated analysis of two Phase III randomized studies. AB - BACKGROUND: Biologics are effective for the treatment of psoriasis. However, treatment outcomes may differ among biologic-naive patients and those switched from previous biological therapies. OBJECTIVES: The study's objective was to investigate efficacy and safety of ixekizumab, a high-affinity anti-interleukin 17A antibody, in patients with psoriasis with and without previous exposure to biologics. METHODS: Data were integrated from the 12-week induction phase of two etanercept-controlled Phase III trials. Patients received 80 mg ixekizumab every 2 weeks (IXE Q2W; N = 736) or every 4 weeks (IXE Q4W; N = 733) following a 160-mg starting dose, or placebo (N = 361). Etanercept (50 mg twice weekly; N = 740) was administered as active control. Psoriasis Area and Severity Index (PASI) 75, PASI 90 and PASI 100 response rates at week 12 were evaluated in patients with or without previous exposure to biologics. Treatment effects were analysed with the Cochran-Mantel-Haenszel test stratified by study; missing values were imputed as non-response. RESULTS: Overall, 497 (19.3%) patients had prior exposure to biologics and 2073 (80.7%) were naive to biologic therapy. PASI 75 was achieved by 91.5% of biologic-experienced patients and 87.7% of biologic-naive patients for IXE Q2W, 76.2% and 82.2% for IXE Q4W, respectively, and 34.6% and 50.7%, respectively, for etanercept. Higher response rates favouring each ixekizumab dose over etanercept within subgroups were also seen regarding PASI 90 and PASI 100. CONCLUSIONS: Contrary to etanercept, the efficacy of ixekizumab was similarly high in patients with and without previous exposure to biologics when administered 80 mg every 2 weeks. PMID- 27696578 TI - Systematic review of psychosocial outcomes for patients with advanced melanoma. AB - BACKGROUND: New advanced melanoma therapies are associated with improved survival; however, quality of survivorship, particularly psychosocial outcomes, for patients overall and those treated with newer therapies is unclear. OBJECTIVE: Synthesize qualitative and quantitative evidence about psychosocial outcomes for advanced (stage III/IV) melanoma patients. METHODS: Five databases were searched (01/01/1980 to 31/01/2016). Inclusion criteria were as follows: advanced melanoma patients or sub-group analysis; assessed psychosocial outcomes; and English language. RESULTS: Fifty-two studies met review criteria (4 qualitative, 48 quantitative). Trials comprise mostly medical not psychosocial interventions, with psychosocial outcomes assessed within broader quality of life measures. Patients receiving chemotherapy or IFN-alpha showed decreased emotional and social function and increased distress. Five trials of newer therapies appeared to show improvements in emotional and social function. Descriptive studies suggest that patients with advanced, versus localized disease, had decreased emotional and social function and increased distress. Contributors to distress were largely unexplored, and no clear framework described coping/adjustment trajectories. Patients with advanced versus localized disease had more supportive care needs, particularly amount, quality, and timing of melanoma-related information, communication with and emotional support from clinicians. Limitations included: lack of theoretical underpinnings guiding study design; inconsistent measurement approaches; small sample sizes; non representative sampling; and cross-sectional design. CONCLUSIONS: Quality trial evidence is needed to clarify the impact of treatment innovations for advanced melanoma on patients' psychosocial well-being. Survivorship research and subsequent translation of that knowledge into programs and services currently lags behind gains in the medical treatment of advanced melanoma, a troubling circumstance that requires immediate and focused attention. PMID- 27696580 TI - Goal Attainment Scaling in Individuals with Upper Limb Spasticity Post Stroke. AB - Focusing on rehabilitation goals is an effective approach for improving function in individuals with spasticity after stroke. The objectives of this study were to examine and map goals of post-stroke individuals with spasticity using the Goal Attainment Scale (GAS) and International Classification of Functioning, Disability and Health (ICF), and to evaluate the impact of botulinum toxin A (BoNTA) on occupational performance based on the type of rehabilitation goals. Thirty-one patients were recruited from an outpatient spasticity management clinic. Each patient set one goal, was injected with BoNTA in their spastic upper limb muscles and received standard rehabilitation services twice a week for four weeks. Twenty-seven participants achieved the expected level, and four exceeded the expected level of their rehabilitation goals. Fifty-five percent of the goals were related to Activity/Participation, and 45% of the goals were categorized in the Body Structures and Function domain of the ICF. Fifteen goals focused on positioning, while 16 goals focused on (independent) activities of daily living (ADL/IADL). Both the positioning and ADL/IADL groups experienced a reduction in MAS following the administration of BoNTA. The positioning group was older and more impaired. Mapping goals to ICF identifies specific targets for intervention, establishes a common language within the interdisciplinary team and contextualizes the ways disability impacts goals. This study is limited by a relatively small sample size and absence of a functional measure. Further studies can explore the development of goal/item banks to advance the use of GAS for spasticity management. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27696579 TI - The Paracoccus denitrificans NarK-like nitrate and nitrite transporters-probing nitrate uptake and nitrate/nitrite exchange mechanisms. AB - Nitrate and nitrite transport across biological membranes is often facilitated by protein transporters that are members of the major facilitator superfamily. Paracoccus denitrificans contains an unusual arrangement whereby two of these transporters, NarK1 and NarK2, are fused into a single protein, NarK, which delivers nitrate to the respiratory nitrate reductase and transfers the product, nitrite, to the periplasm. Our complementation studies, using a mutant lacking the nitrate/proton symporter NasA from the assimilatory nitrate reductase pathway, support that NarK1 functions as a nitrate/proton symporter while NarK2 is a nitrate/nitrite antiporter. Through the same experimental system, we find that Escherichia coli NarK and NarU can complement deletions in both narK and nasA in P. denitrificans, suggesting that, while these proteins are most likely nitrate/nitrite antiporters, they can also act in the net uptake of nitrate. Finally, we argue that primary sequence analysis and structural modelling do not readily explain why NasA, NarK1 and NarK2, as well as other transporters from this protein family, have such different functions, ranging from net nitrate uptake to nitrate/nitrite exchange. PMID- 27696582 TI - ROR2 in the adult mouse testis. PMID- 27696581 TI - Predator-prey interactions amongst Permo-Triassic terrestrial vertebrates as a deterministic factor influencing faunal collapse and turnover. AB - Unlike modern mammalian communities, terrestrial Paleozoic and Mesozoic vertebrate systems were characterized by carnivore faunas that were as diverse as their herbivore faunas. The comparatively narrow food base available to carnivores in these paleosystems raises the possibility that predator-prey interactions contributed to unstable ecosystems by driving populations to extinction. Here, we develop a model of predator-prey interactions based on diversity, abundance and body size patterns observed in the Permo-Triassic vertebrate fossil record of the Karoo Basin, South Africa. Our simulations reflect empirical evidence that despite relatively high carnivore: herbivore species ratios, herbivore abundances were sufficient for carnivores to maintain required intake levels through most of the Karoo sequence. However, high mortality rates amongst herbivore populations, even accounting for birth rates of different-sized species, are predicted for assemblages immediately preceding the end-Guadalupian and end-Permian mass extinctions, as well as in the Middle Triassic when archosaurs replaced therapsids as the dominant terrestrial fauna. These results suggest that high rates of herbivore mortality could have played an important role in biodiversity declines leading up to each of these turnover events. Such declines would have made the systems especially vulnerable to subsequent stochastic events and environmental perturbations, culminating in large-scale extinctions. PMID- 27696583 TI - Yield and complications of kidney biopsy over two decades in a tertiary pediatric center. AB - BACKGROUND: Kidney biopsy serves as an adjunct for the diagnosis of renal disease, but it is not always productive. This study evaluated the yield and risks of kidney biopsies performed in 1995-2014 at a tertiary pediatric medical center. METHODS: The medical files of all patients who underwent closed percutaneous biopsy for various indications in native or transplanted kidneys were retrospectively reviewed for patient characteristics, technical and histopathologic findings, biopsy yield, and biopsy complications. Biopsy yield was considered positive if findings confirmed a probable diagnosis or led to a change in clinical diagnosis, disease severity/activity grade, treatment strategy, or prognosis; and negative, if findings were non-informative and in cases of technical failure. RESULTS: During the study period, 216 biopsies were performed on native kidneys and 84 on transplanted kidneys. In the transplanted kidney group, the most common indications for biopsy were decreased glomerular filtration rate and suspected rejection. Rates of positive biopsy yield were 86.6% in the native kidney group and 82.1% in the transplanted kidney group; the difference was not statistically significant. Significant between-group differences were found in various technical and histopathological parameters, patient age at biopsy, and sex distribution. In the native kidney group, positive biopsy yield was associated with the presence of nephrotic-range proteinuria. Post-procedural complications occurred in three patients (1.3%) with native kidneys, and in one patient (1.1%) with a transplanted kidney. CONCLUSIONS: Kidney biopsy is an efficient and safe procedure in both native and transplanted kidneys and provides helpful diagnostic information in most cases in which it is deemed necessary.

AB - Kinesin family member 1B (KIF1B) is an important microtubule-dependent monomeric motor in mammals, although little is known about its role in meiosis. We profiled KIF1B expression and localization during oocyte maturation and early embryonic development in mice, revealing a dynamic pattern throughout meiotic progression. Depletion or inhibition of KIF1B leads to abnormal polar body extrusion, disordered spindle dynamics, defects in chromosome congression, increased aneuploidy, and impaired embryonic development. Further, KIF1B depletion affects the distribution of mitochondria and abundance of ATP. Taken together, our study demonstrates that mouse KIF1B is important for spindle assembly, chromosome congression, and mitochondrial distribution during oocyte maturation and early embryonic development.

AB - Phenotypic traits such as ornaments and armaments are generally shaped by sexual selection, which often favours larger and more elaborate males compared to females. But can sexual selection also influence the brain? Previous studies in vertebrates report contradictory results with no consistent pattern between variation in brain structure and the strength of sexual selection. We hypothesize that sexual selection will act in a consistent way on two vertebrate brain regions that directly regulate sexual behaviour: the medial preoptic nucleus (MPON) and the ventromedial hypothalamic nucleus (VMN). The MPON regulates male reproductive behaviour whereas the VMN regulates female reproductive behaviour and is also involved in male aggression. To test our hypothesis, we used high resolution magnetic resonance imaging combined with traditional histology of brains in 14 dragon lizard species of the genus Ctenophorus that vary in the strength of precopulatory sexual selection. Males belonging to species that experience greater sexual selection had a larger MPON and a smaller VMN. Conversely, females did not show any patterns of variation in these brain regions. As the volumes of both these regions also correlated with brain volume (BV) in our models, we tested whether they show the same pattern of evolution in response to changes in BV and found that the do. Therefore, we show that the primary brain nuclei underlying reproductive behaviour in vertebrates can evolve in a mosaic fashion, differently between males and females, likely in response to sexual selection, and that these same regions are simultaneously evolving in concert in relation to overall brain size.

AB - PURPOSE: Valvuloarterial impedance (ZVA ), estimating left ventricle (LV) afterload, has been proposed in transthoracic echocardiography (TTE) as a predictor of mortality in aortic valve stenosis (AVS). However, its calculation differs from arterial characteristic impedance (ZC ). Our aim was to apply the concept of ZC calculation to estimate ZVA from MR with carotid tonometry and to evaluate these indices through their associations with symptoms, LV diastolic function and aortic stiffness. MATERIALS AND METHODS: In 40 patients with AVS (76 +/- 13 years), ZVA-TI derived from velocity time integral and E/Ea were estimated by TTE. ZVA-INS , based on ZC formula, calculated as the instantaneous pressure gradient to peak flow ratio and aortic compliance were estimated by using MRI at 1.5 Tesla. RESULTS: Both ZVA estimates were higher in symptomatic than asymptomatic patients (707 +/- 22 versus 579 +/- 53 dyne.s/cm5 , P = 0.031 for ZVA-INS and 4.35 +/- 0.16 versus 3.33 +/- 0.38 mmHg.m2 /mL, P = 0.018 for ZVA-TI ). Although they were both associated with aortic compliance (r = -0.45; P = 0.006 for ZVA-INS and r = -0.43; P = 0.008 for ZVA-TI ) only ZVA-INS was associated with E/Ea (r = 0.50; P < 0.001). In multivariate analysis to identify determinants of E/Ea, a model including age, mean blood pressure, LV ejection fraction, LV mass, and aortic valve area was performed (R2 = 0.41; P < 0.01). When ZVA-INS was added to the model, its overall significance was higher R2 = 0.56 (P < 0.01) and ZVA-INS and LV mass were the only significant determinants. CONCLUSION: ZVA-INS was more strongly associated with diastolic dysfunction than usual parameters quantifying AVS severity. This new ZVA estimate could improve LV afterload evaluation.

AB - Local adaptation plays a key role in the evolutionary trajectory of host-pathogen interactions. However, the genetic architecture of local adaptation in host pathogen systems is poorly understood. Fungal plant pathogens in agricultural ecosystems provide highly tractable models to quantify phenotypes and map traits to corresponding genomic loci. The outcome of crop-pathogen interactions is thought to be governed largely by gene-for-gene interactions. However, recent studies showed that virulence can be governed by quantitative trait loci and that many abiotic factors contribute to the outcome of the interaction. After introducing concepts of local adaptation and presenting examples from wild plant pathosystems, we focus this review on a major pathogen of wheat, Zymoseptoria tritici, to show how a multitude of traits can affect local adaptation. Zymoseptoria tritici adapted to different thermal environments across its distribution range, indicating that thermal adaptation may limit effective dispersal to different climates. The application of fungicides led to the rapid evolution of multiple, independent resistant populations. The degree of colony melanization showed strong pleiotropic effects with other traits, including trade offs with colony growth rates and fungicide sensitivity. The success of the pathogen on its host can be assessed quantitatively by counting pathogen reproductive structures and measuring host damage based on necrotic lesions. Interestingly, these two traits can be weakly correlated and depend both on host and pathogen genotypes. Quantitative trait mapping studies showed that the genetic architecture of locally adapted traits varies from single loci with large effects to many loci with small individual effects. We discuss how local adaptation could hinder or accelerate the development of epidemics in agricultural ecosystems. PMID- 27696588 TI - Telomere length reflects reproductive effort indicated by corticosterone levels in a long-lived seabird. AB - Telomere length (TL) is a candidate biomarker of ageing and phenotypic quality, but little is known of the (physiological) causes of TL variation. We previously showed that individual common terns Sterna hirundo with high reproductive success had short telomeres independent of age, and this pattern was particularly strong in the longer telomeres of the within-individual TL distribution. To test whether this relation can be attributed to effects of reproductive effort, we investigated baseline corticosterone in relation to reproductive success (number of fledglings) and TL. In this context, we assume that variation in baseline corticosterone can be interpreted as index of energy expenditure and allostatic load. Males with higher corticosterone levels during incubation, compared between and within individuals, achieved higher reproductive success and had shorter telomeres. The effect on telomeres was more pronounced in corticosterone measured later in incubation and in the longer telomeres of the within-individual TL distribution. Female corticosterone level during incubation was neither related to reproductive success nor to TL. That we observed these effects only in males mirrors different parental roles during reproduction in the common tern, where males do most of the chick provisioning. The negative association between reproductive success and TL suggests individual differences in reproductive effort as reflected in, or mediated by, baseline corticosterone. We see this result as a promising step towards unravelling the physiological causes of variation in TL and the costs of reproduction. PMID- 27696589 TI - Influence of sleep duration on cortical oxygenation in elderly individuals. AB - AIM: Short sleep duration is a risk factor for cardiovascular diseases. Cerebral blood flow and its regulation are affected by pathological conditions commonly observed in the elderly population, such as dementia, atherosclerosis, diabetes mellitus (DM), stroke, and hypertension. The purpose of this study was to examine the influence of sleep duration on cortical oxygenated hemoglobin (OxyHb) using near-infrared spectroscopy (NIRS). METHODS: Seventy-three individuals (age, 70.1 +/- 3.9 years, 51 men and 22 women) participated in this study. Cortical OxyHb levels were measured with NIRS. We evaluated age, body mass index (BMI), smoking status, alcohol intake, sleep duration, hypertension, DM, and hyperlipidemia using a questionnaire. Blood pressure was measured using plethysmography. RESULTS: Peak OxyHb and area under the NIRS curve significantly decreased in participants with sleep duration <7 h compared with those with sleep duration >=7 h (0.136 +/- 0.212 mM.mm vs 0.378 +/- 0.342 mM.mm, P = 0.001; 112.0 +/- 243.6 vs 331.7 +/- 428.7, P = 0.012, respectively). Sleep duration was significantly correlated with peak OxyHb level and area under the NIRS curve (r = 0.378, P = 0.001; r = 0.285, P = 0.015, respectively). Multiple regression analysis, including age, BMI, sex, smoking status, alcohol intake, sleep duration, hypertension, DM, and hyperlipidemia revealed that sleep duration was the only significant independent factor associated with peak OxyHb and area under the NIRS curve (beta = 0.343, P = 0.004; beta = 0.244, P = 0.049, respectively), and smoking status was independently correlated with time to the peak OxyHb (beta = 0.319, P = 0.009). CONCLUSION: Sleep duration may be an important factor that influences cortical oxygenation in the elderly population.

PMID- 27696591 TI - Inflammation-induced myeloid-derived suppressor cells associated with squamous cell carcinoma of the head and neck. AB - BACKGROUND: The purpose of this study was to present our assessment of the significance of myeloid-derived suppressor cells (MDSCs) in head and neck squamous cell carcinoma (HNSCC). METHODS: We examined the percentage of MDSCs in the peripheral blood of patients with HNSCC. The relationship among MDSC recruitment, tumor progression, and cyclooxygenase (COX)-2 inhibition was also evaluated by animal models. RESULTS: Circulating MDSCs were significantly increased in patients with HNSCC compared with healthy people, and this was associated with the clinical tumor burden. In immunocompetent 4-nitroquinoline-1 oxide (4-NQO)-induced oral tumor and immunocompromised tumor implantation animal models, MDSC recruitment was associated with the duration of 4-NQO treatment and tumor progression. The responsible mechanisms included the suppressive ability of T-cell proliferation and augmenting angiogenesis by MDSC. Blockade of COX-2 attenuated the induction and function of MDSCs and subsequently inhibited tumor growth. CONCLUSION: The levels of MDSC are linked with tumor progression in HNSCC. Moreover, targeting COX-2 could be a promising strategy for the treatment of HNSCC. (c) 2016 Wiley Periodicals, Inc. Head Neck 39: 347-355, 2017. PMID- 27696592 TI - "Can touch this": Cross-modal shape categorization performance is associated with microstructural characteristics of white matter association pathways. AB - Previous studies on visuo-haptic shape processing provide evidence that visually learned shape information can transfer to the haptic domain. In particular, recent neuroimaging studies have shown that visually learned novel objects that were haptically tested recruited parts of the ventral pathway from early visual cortex to the temporal lobe. Interestingly, in such tasks considerable individual variation in cross-modal transfer performance was observed. Here, we investigate whether this individual variation may be reflected in microstructural characteristics of white-matter (WM) pathways. We first trained participants on a fine-grained categorization task of novel shapes in the visual domain, followed by a haptic categorization test. We then correlated visual training-performance and haptic test-performance, as well as performance on a symbol-coding task requiring visuo-motor dexterity with microstructural properties of WM bundles potentially involved in visuo-haptic processing (the inferior longitudinal fasciculus [ILF], the fronto-temporal part of the superior longitudinal fasciculus [SLFft ] and the vertical occipital fasciculus [VOF]). Behavioral results showed that haptic categorization performance was good on average but exhibited large inter-individual variability. Haptic performance also was correlated with performance in the symbol-coding task. WM analyses showed that fast visual learners exhibited higher fractional anisotropy (FA) in left SLFft and left VOF. Importantly, haptic test-performance (and symbol-coding performance) correlated with FA in ILF and with axial diffusivity in SLFft . These findings provide clear evidence that individual variation in visuo-haptic performance can be linked to microstructural characteristics of WM pathways. Hum Brain Mapp 38:842-854, 2017.

AB - INTRODUCTION: Approximately 10-20% of ICD recipients receive inappropriate device therapies. The purpose of this study was to compare the frequency of inappropriate therapies (IT) between men and women enrolled in MADIT II and MADIT CRT, and assess for potential adverse outcomes. METHODS: The electrograms for each ICD or CRT-D therapy, defined as either ATP or shock, were reviewed by adjudication committees for both studies. ICD therapy was considered inappropriate if it was delivered for reasons other than VT/VF. The rhythm triggering IT was categorized as atrial fibrillation/flutter, SVT, or inappropriate sensing when possible. RESULTS: One thousand nine hundred and fifty four men and 556 women received ICD or CRT-D devices. The risk of IT was significantly lower in women than men (9.2% vs. 13.5%, P = 0.006). The most common cause of IT in men was atrial fibrillation (38%) and SVT in women (43%). Inappropriate shock was not associated with increased mortality in either women (HR 0.82 [95% CI 0.11-6.08]; P = NS) or men (HR 1.37 [95% CI 0.75-2.48]; P = NS) by multivariate analysis. Conversely, appropriate shock therapy strongly correlated with increased risk of death during subsequent post-shock follow-up in women (HR 5.99 [95% CI 2.75-13.02]; P < 0.0001) and men (HR 2.61 [95% CI 1.82 3.74]; P < 0.0001). CONCLUSIONS: Women experience significantly less IT than men, partially explained by the increased frequency of atrial fibrillation in men. IT was not associated with increased mortality in either sex. Appropriate shock therapy was a strong predictor of death in both, with women showing a 2-fold higher risk than men during post-shock long-term follow-up. PMID- 27696594 TI - Comparative study of host response to chytridiomycosis in a susceptible and a resistant toad species. AB - In the past century, recently emerged infectious diseases have become major drivers of species decline and extinction. The fungal disease chytridiomycosis has devastated many amphibian populations and exacerbated the amphibian conservation crisis. Biologists are beginning to understand what host traits contribute to disease susceptibility, but more work is needed to determine why some species succumb to chytridiomycosis while others do not. We conducted an integrative laboratory experiment to examine how two toad species respond to infection with the pathogen Batrachochytrium dendrobatidis in a controlled environment. We selected two toad species thought to differ in susceptibility - Bufo marinus (an invasive and putatively resistant species) and Bufo boreas (an endangered and putatively susceptible species). We measured infection intensity, body weight, histological changes and genomewide gene expression using a custom assay developed from transcriptome sequencing. Our results confirmed that the two species differ in susceptibility with the more susceptible species, B. boreas, showing higher infection intensities, loss in body weight, more dramatic histological changes and larger perturbations in gene expression. We found key differences in skin expression responses in multiple pathways including upregulation of skin integrity-related genes in the resistant B. marinus. Together, our results show intrinsic differences in host response between related species, which are likely to be important in explaining variation in response to a deadly emerging pathogen in wild populations. Our study also underscores the importance of understanding differences among host species to better predict disease outcomes and reveal generalities about host response to emerging infectious diseases of wildlife. PMID- 27696595 TI - Copy number profiling of tumor suppressor genes in head and neck cancer. AB - BACKGROUND: Sensitive and reliable new biomarkers are needed in head and neck cancer to predict the outcome and for therapy that is more effective. Copy number alterations are frequent and play a critical role in cancer. METHODS: Copy number alterations of 24 tumor suppressor genes in head and neck cancer were analyzed simultaneously in matched tumor and normal samples from 93 patients using multiplex ligation-dependent probe amplification (MLPA). RESULTS: Chromosomes 3p and 9p displayed the most common alterations. The gene displaying most frequent losses was the mutL homolog 1 (MLH1) gene, followed by the cyclin-dependent kinase inhibitor 2A (CDKN2A) and CDKN2B genes. A significant correlation was observed between the CDKN2A and CDKN2B genes. The tissue inhibitor of metalloproteinase (TIMP)3 gene alterations were observed in 8 tumors. CONCLUSION: Our data confirm previous observations and suggest that losses of the MLH1 and CDKN2 genes and alterations of the TIMP3 gene play an important role in head and neck carcinogenesis.

AB - OBJECTIVES: Baclofen is a zwitterion molecule where increased ions in the excipient increase the solubility. We developed baclofen in a stable solution similar to cerebrospinal fluid (CSF) without bicarbonate and proteins to improve the solubility of the baclofen and to reduce the potential toxicity to the central nervous system (CNS) and subarachnoid space. The objective is to develop a solution of baclofen wherein baclofen is solubilized in a multivalent physiological ion solution such as artificial cerebrospinal fluid (aCSF) at a concentration from 2 mg/cc to 10 mg/cc. METHODS: First, to determine the solubility of Baclofen in aCSF, solubility was determined at six different pH levels at 37 degrees C, by the addition of aCSF to a known amount of Baclofen. The final concentrations were confirmed by high performance liquid chromatography (HPLC) analysis. Second, the stability of Baclofen at 4 mg/cc investigated in a test manufacturing batch utilizing standard methods of production of 1500 20 cc vials inverted for 18 months at 25 degrees C at 60% humidity. The stability and purity of the baclofen was verified at 18 months by HPLC analysis. RESULTS: Baclofen was initially soluble between pH of 6-8 above 7 mg/cc but fell back to 6.3-5.8 mg/cc level with time. Baclofen produced in vials with inversion were noted to be stable at 4 mg/cc at 18 months with less than 2% breakdown of the baclofen in solution. CONCLUSION: Baclofen is much more soluble in artificial CSF than normal saline. The artificial CSF may also be less toxic to the subarachnoid space than saline.

AB - This report describes the postmaxillectomy prosthetic rehabilitation of a child with maxillary chondrosarcoma over an 8-year period. Specifically, it (1) describes the planning and rehabilitation procedures carried out during the period from before the operation to the time when the patient started elementary school and (2) reports the results of evaluations of the patient's oral and psychosocial function conducted during the school phase. The prosthetic treatment plan was separated into two phases (the preschool and school phases) and was started prior to surgery, when an immediate surgical obturator was designed by the surgeons. After the operation, it was considered important to provide the patient and her mother with training regarding how the defect should be cleaned, trismus prevention, and how the prosthesis should be fitted. In addition, esthetic improvements and the ability to speak clearly were also targeted during treatment planning. After surgery, obturators were fabricated in a conventional manner and fitted at the ages of 2, 4, 6, 8, and 10 years. The patient's oral function during the use of the obturators was evaluated objectively. Marked improvements in oral function were seen during both treatment phases. The patient's ability to perform psychosocial functions at school also improved during the use of the obturators. PMID- 27696597 TI - The fungal cultivar of leaf-cutter ants produces specific enzymes in response to different plant substrates. AB - Herbivores use symbiotic microbes to help derive energy and nutrients from plant material. Leaf-cutter ants are a paradigmatic example, cultivating their mutualistic fungus Leucoagaricus gongylophorus on plant biomass that workers forage from a diverse collection of plant species. Here, we investigate the metabolic flexibility of the ants' fungal cultivar for utilizing different plant biomass. Using feeding experiments and a novel approach in metaproteomics, we examine the enzymatic response of L. gongylophorus to leaves, flowers, oats or a mixture of all three. Across all treatments, our analysis identified and quantified 1766 different fungal proteins, including 161 putative biomass degrading enzymes. We found significant differences in the protein profiles in the fungus gardens of subcolonies fed different plant substrates. When provided with leaves or flowers, which contain the majority of their energy as recalcitrant plant polymers, the fungus gardens produced more proteins predicted to break down cellulose: endoglucanase, exoglucanase and beta-glucosidase. Further, the complete metaproteomes for the leaves and flowers treatments were very similar, while the mixed substrate treatment closely resembled the treatment with oats alone. This indicates that when provided a mixture of plant substrates, fungus gardens preferentially break down the simpler, more digestible substrates. This flexible, substrate-specific enzymatic response of the fungal cultivar allows leaf-cutter ants to derive energy from a wide range of substrates, which likely contributes to their ability to be dominant generalist herbivores. PMID- 27696599 TI - Corrigendum. PMID- 27696600 TI - Effects of increasing root carbon investment on the mortality and resprouting of Haloxylon ammodendron seedlings under drought. AB - Tree mortality induced by drought is one of the most complex processes in ecology. Although two mechanisms associated with water and carbon balance are proposed to explain tree mortality, outstanding problems still exist. Here, in order to test how the root system benefits survival and resprouting of Haloxylon ammodendron seedlings, we examined the various water- and carbon-related physiological indicators (shoot water potential, photosynthesis, dark respiration, hydraulic conductance and non-structural carbohydrates [NSC]) of H. ammodendron seedlings, which were grown in drought and control conditions throughout a grow season in greenhouse. The survival time of the seedling root system (died 70 days after drought) doubled the survival time of the shoot (died at 35 days). Difference in survival time between shoot and root resulted from sustained root respiration supported by increased NSC in roots under drought. Furthermore, investment into the root contributed to resprouting following drought. Based on these results, a death criterion is proposed for this species. The time sequence of major events indicated that drought shifted carbon allocation between shoot and root and altered the flux among different sinks (growth, respiration or storage). The interaction of water and carbon processes determined death or survival of droughted H. ammodendron seedlings. These findings revealed that the 'root protection' strategy is critical in determining survival and resprouting of this species, and provided insights into the effects of carbon and water dynamics on tree mortality. PMID- 27696601 TI - Disseminated nocardiosis after unrelated bone marrow transplantation. AB - Nocardiosis is a rare bacterial infection occurring mainly in patients with deficient cell-mediated immunity. Although disseminated nocardiosis after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a rare complication, it is associated with high mortality. Moreover, after allo-HSCT, nocardiosis may be mistaken for other bacterial or fungal infections because clinical and radiographic findings of pulmonary, cerebral, and cutaneous nocardiosis lesions are non-specific. Here, we report a case of disseminated nocardiosis (caused by Nocardia abscessus) with skin, pulmonary, liver, lymph node, and multiple brain abscesses in a patient after allo-HSCT. The patient initially responded clinically and radiographically to imipenem/cilastin and trimethoprim-sulfamethoxazole therapy. Clinicians should be aware of the possibility of nocardiosis in allo-HSCT recipients who are treated with multiple immunosuppressive agents to control chronic graft-versus-host disease. Accurate diagnosis and identification of disseminated nocardiosis is important to ensure administration of the correct antibiotic regimen. PMID- 27696602 TI - Killing the spores of Bacillus species by molecular iodine. AB - AIMS: To determine the responses of spores of Bacillus subtilis and Bacillus anthracis surrogate Bacillus thuringiensis Al Hakam to I2 treatment. METHODS AND RESULTS: Spores of B. subtilis and B. thuringiensis killed by aqueous 30 degrees C-I2 could germinate, and their inner membrane (IM) was intact. Spore coats were important in I2 resistance, DNA-protective proteins were not important, and survivors of I2 treatment were not mutagenized. Viabilities of I2 -treated, 90 98% killed spores were much lower on high-salinity media, and the treated spores were more heat sensitive than the untreated spores. Germinated I2 -killed spores were dead as determined by staining with nucleic acid dyes, and many appeared to have been lysed. CONCLUSIONS: Aqueous I2 appeared to kill B. subtilis and B. thuringiensis spores such that spores lyse soon after they germinate, and not by causing DNA damage or rupture of spores' IM. I2 treatment also generated many damaged spores that could only be recovered under nonstressful conditions. SIGNIFICANCE AND IMPACT OF THE STUDY: This work shows that spores of the model organism B. subtilis, and B. thuringiensis, a surrogate for B. anthracis spores, exhibit similar mechanisms of resistance to and killing by I2 . Generation by I2 treatment of conditionally dead spores indicates that appropriate media are essential to efficiently enumerate viable I2 -treated spores. PMID- 27696603 TI - Enhanced subject-specific resting-state network detection and extraction with fast fMRI. AB - Resting-state networks have become an important tool for the study of brain function. An ultra-fast imaging technique that allows to measure brain function, called Magnetic Resonance Encephalography (MREG), achieves an order of magnitude higher temporal resolution than standard echo-planar imaging (EPI). This new sequence helps to correct physiological artifacts and improves the sensitivity of the fMRI analysis. In this study, EPI is compared with MREG in terms of capability to extract resting-state networks. Healthy controls underwent two consecutive resting-state scans, one with EPI and the other with MREG. Subject level independent component analyses (ICA) were performed separately for each of the two datasets. Using Stanford FIND atlas parcels as network templates, the presence of ICA maps corresponding to each network was quantified in each subject. The number of detected individual networks was significantly higher in the MREG data set than for EPI. Moreover, using short time segments of MREG data, such as 50 seconds, one can still detect and track consistent networks. Fast fMRI thus results in an increased capability to extract distinct functional regions at the individual subject level for the same scan times, and also allow the extraction of consistent networks within shorter time intervals than when using EPI, which is notably relevant for the analysis of dynamic functional connectivity fluctuations.

AB - Experimentally induced tonic muscle pain evokes divergent muscle vasoconstrictor responses, with some individuals exhibiting a sustained increase in muscle sympathetic nerve activity (MSNA), and others a sustained decrease. These patterns cannot be predicted from an individual's baseline physiological or psychological measures. The aim of this study was to investigate whether the different muscle sympathetic responses to tonic muscle pain were associated with differential changes in regional brain activity. Functional magnetic resonance imaging (fMRI) of the brain was performed concurrently with microelectrode recording of MSNA from the peroneal nerve during a 40-min infusion of hypertonic saline into the ipsilateral tibialis anterior muscle. MSNA increased in 26 and decreased in 11 of 37 subjects during tonic muscle pain. Within the prefrontal and cingulate cortices, precuneus, nucleus accumbens, caudate nucleus, and dorsomedial hypothalamus, blood oxygen level dependent (BOLD) signal intensity increased in the increasing-MSNA group and remained at baseline or decreased in the decreasing-MSNA group. Similar responses occurred in the dorsolateral pons and in the region of the rostral ventrolateral medulla. By contrast, within the region of the dorsolateral periaqueductal gray (dlPAG) signal intensity initially increased in both groups but returned to baseline levels only in the increasing MSNA group. These results suggest that the divergent sympathetic responses to muscle pain result from activation of a neural pathway that includes the dlPAG, an area thought to be responsible for the behavioral and cardiovascular responses to psychological rather than physical stressors.

PMID- 27696606 TI - Secretory glands and microvascular systems imaged in aqueous solution by atmospheric scanning electron microscopy (ASEM). AB - Exocrine glands, e.g., salivary and pancreatic glands, play an important role in digestive enzyme secretion, while endocrine glands, e.g., pancreatic islets, secrete hormones that regulate blood glucose levels. The dysfunction of these secretory organs immediately leads to various diseases, such as diabetes or Sjogren's syndrome, by poorly understood mechanisms. Gland-related diseases have been studied by optical microscopy (OM), and at higher resolution by transmission electron microscopy (TEM) of Epon embedded samples, which necessitates hydrophobic sample pretreatment. Here, we report the direct observation of tissue in aqueous solution by atmospheric scanning electron microscopy (ASEM). Salivary glands, lacrimal glands, and pancreas were fixed, sectioned into slabs, stained with phosphotungstic acid (PTA), and inspected in radical scavenger d-glucose solution from below by an inverted scanning electron microscopy (SEM), guided by optical microscopy from above to target the tissue substructures. A 2- to 3-um specimen thickness was visualized by the SEM. In secretory cells, cytoplasmic vesicles and other organelles were clearly imaged at high resolution, and the former could be classified according to the degree of PTA staining. In islets of Langerhans, the microvascular system used as an outlet by the secretory cells was also clearly observed. Microvascular system is also critically involved in the onset of diabetic complications and was clearly visible in subcutaneous tissue imaged by ASEM. The results suggest the use of in-solution ASEM for histology and to study vesicle secretion systems. Further, the high-throughput of ASEM makes it a potential tool for the diagnosis of exocrine and endocrine-related diseases. PMID- 27696605 TI - Episodic memory of odors stratifies Alzheimer biomarkers in normal elderly. AB - OBJECTIVE: The objective of this study was to relate a novel test of identifying and recalling odor percepts to biomarkers of Alzheimer's disease (AD) in well characterized elderly individuals, ranging from cognitively normal to demented. METHODS: One hundred eighty-three participants (cognitively normal: n = 70; subjective cognitive concerns: n = 74; mild cognitive impairment [MCI]: n = 29, AD dementia: n = 10) were administered novel olfactory tests: the Odor Percept IDentification (OPID) and the Percepts of Odor Episodic Memory (POEM) tests. Univariate cross-sectional analyses of performance across diagnoses; logistic regression modeling, including covariates of age, sex, education, APOE genotype, and neuropsychological test scores; and linear mixed modeling of longitudinal cognitive scores were performed. Amyloid deposition and MRI volumetrics were analyzed in a subset of participants. RESULTS: Accuracy of identification and episodic memory of odor percepts differed significantly across diagnosis and age, with progressively worse performance across degrees of impairment. Among the participants who were cognitively normal or had subjective cognitive concerns, poorer than expected performance on the POEM test (based on the same individual's performance on the OPID and odor discrimination tests) was associated with higher frequencies of the APOE epsilon4 allele, thinner entorhinal cortices, and worse longitudinal trajectory of Logical Memory scores. INTERPRETATION: Selective impairment of episodic memory of odor percepts, relative to identification and discrimination of odor percepts revealed by this novel POEM battery, is associated with biomarkers of AD in a well-characterized pre-MCI population. These affordable, noninvasive olfactory tests offer potential to identify clinically normal individuals who have greater likelihood of future cognitive decline. Ann Neurol 2016;80:846-857. PMID- 27696607 TI - The Volume-Outcome Effect: Impact on Trial-to-Permanent Conversion Rates in Spinal Cord Stimulation. AB - OBJECTIVES: Conversion rates from trial leads to permanent spinal cord stimulation (SCS) systems have important implications for healthcare resource utilization (HCRU) and pain management. We hypothesized that there is a volume outcome effect, with chronic pain patients who visit high volume SCS implanters will have higher trial-to-permanent conversion rates. MATERIALS AND METHODS: We designed a large, retrospective analysis using the Truven MarketScan database analyzing adult SCS patients with provider information available, with or without IPG implantation from the years 2007 to 2012 was designed. Patients were divided into three provider-based groups: high (>25), medium (9-24), and low (3-8) volume providers. Univariate and multivariate models identified factors associated with successful conversion. RESULTS: A total of 17,850 unique trial implants were performed by 3028 providers. Of 13,879 patients with baseline data available, 8981 (64.7%) progressed to permanent SCS. Higher volume providers were associated with slightly higher conversion rates (65.9% vs. 63.3% low volume, p = 0.029), explant rates (9.2% vs. 7.7% medium volume, p = 0.026), younger age (52.0 +/- 13.4 years vs. 53.0 +/- 13.4 years, p = 0.0026), Medicare/Medicaid (47.8% vs. 35.0% low volume, p < 0.0001), Southern region (53.5% vs. 38.9% low volume, p < 0.0001), and higher Charlson comorbidity scores (1.0 [SD = 1.4], p = 0.0002). Multivariate regression results showed female gender (1.13 [95% CI: 1.05-1.22], p < 0.001) and high volume providers associated with higher odds of successful trial conversion (1.12 [95% CI: 1.02-1.22], p = 0.014). CONCLUSIONS: In this nationwide analysis, high volume providers achieved higher trial-to-permanent SCS conversion rates than lower volume providers. The study has implications for both training requirements and referral patterns to delineate minimum implant experience necessary for provider proficiency. Future studies may be useful to understand HCRU differences. PMID- 27696608 TI - Repetitive DNA methylome analysis by small-scale and single-cell shotgun bisulfite sequencing. AB - Whole-genome shotgun bisulfite sequencing (WG-SBS) is currently the most powerful tool available for understanding genomewide cytosine methylation with single-base resolution; however, the high sequencing cost limits its widespread application, particularly for mammalian genomes. We mapped high- to low-coverage SBS short reads of mouse and human female developing germ cells to consensus sequences of repetitive elements that were multiplied in the respective host genome. This mapping strategy effectively identified active and evolutionarily young retrotransposon subfamilies and centromeric satellite repeats that were resistant to DNA demethylation during the investigated progressive stages of germ cell development. Notably, quantities of only tens of thousands of uniquely mapped reads provided sufficient sensitivity to allow for methylation analyses of multiple retrotransposons and satellite repeats in mice. Furthermore, we produced SBS results from single female murine germ cells by an improved multiplexing and amplification-free SBS method (scPBAT). The scPBAT results quantitatively provided >=5* sequencing coverage for at least 30 repeats, and the individual methylation patterns detected were similar to the bulk cell-based results. Our single-cell methylome sequencing technique will allow researchers to investigate intergenic methylation characteristics from limited amounts of mammalian cells as well as cells from other organisms with genomic annotations.

PMID- 27696611 TI - PRDM1/BLIMP1 is widely distributed to the nascent fetal-placental interface in the mouse gastrula. AB - BACKGROUND: PRDM1 is a transcriptional repressor that contributes to primordial germ cell (PGC) development. During early gastrulation, epiblast-derived PRDM1 is thought to be restricted to a lineage-segregated germ line in the allantois. However, given recent findings that PGCs overlap an allantoic progenitor pool that contributes widely to the fetal-umbilical interface, posterior PRDM1 may also contribute to soma. RESULTS: Within the posterior mouse gastrula (early streak, 12-s stages, embryonic days ~6.75-9.0), PRDM1 localized to all tissues containing putative PGCs; however, PRDM1 was also found in all three primary germ layers, their derivatives, and two presumptive growth centers, the allantoic core domain and ventral ectodermal ridge. While PRDM1 and STELLA colocalized predominantly within the hindgut, where putative PGCs reside, other colocalizing cells were found in non-PGC sites. Additional PRDM1 and STELLA cells were found independent of each other throughout the posterior region, including the hindgut. The Prdm1-Cre-driven reporter supported PRDM1 localization in the majority of sites; however, some Prdm1 descendants were found in sites independent of PRDM1 protein, including allantoic mesothelium and hindgut endoderm. CONCLUSIONS: Posterior PRDM1 contributes more broadly to the developing fetal-maternal connection than previously recognized, and PRDM1 and STELLA, while overlapping in putative PGCs, also co-localize in several other tissues.

AB - The ability to represent the mental states of other agents is referred to as Theory of Mind (ToM). A developmental breakthrough in ToM consists of understanding that others can have false beliefs about the world. Recently, infants younger than 2 years of age have been shown to pass novel implicit false belief tasks. However, the processes underlying these tasks and their relation to later-developing explicit false belief understanding, as well as to other cognitive abilities, are not yet understood. Here, we study a battery of implicit and explicit false belief tasks in 3- and 4-year-old children, relating their performance to linguistic abilities and executive functions. The present data show a significant developmental change from failing explicit false belief tasks at 3 years of age to passing them at the age of 4, while both age groups pass implicit false belief tasks. This differential developmental trajectory is reflected by the finding that explicit and implicit false belief tasks do not correlate. Further, we demonstrate that explicit false belief tasks correlate with syntactic and executive functions, whereas implicit false belief tasks do not. The study thus indicates that the processes underlying implicit false belief tasks are different from later-developing explicit false belief understanding. Moreover, our results speak for a critical role of syntactic and executive functions for passing standard explicit false belief tasks in contrast to implicit tasks.

AB - PURPOSE: To determine the elastic properties of five ceramic systems with different compositions (lithium disilicate vs. feldspathic ceramics) and processing methods and compare the stress distribution in premolars in the interface with inlays made with these systems loaded with the maximum normal bite force (665 N) using 3D finite element analysis (FEA). MATERIALS AND METHODS: The elastic properties of five ceramic restoration materials (IPS e.max Press, IPS e.max CAD, Vita PM9, Vita Mark II, Vita VM7) were obtained using the ultrasonic pulse-echo method. Three-dimensional FEA simplified models of maxillary premolars restored with these ceramic materials were created. The models were loaded with a load at the two nodes on the occlusal surface in the middle of the tooth, 2 mm from the outside of the tooth, simulating a loading ball with a radius of 6 mm. RESULTS: The means values of density (g/cm3), Young's modulus (GPa), and Poison's ratio was 2.6 +/- 0.3, 82.3 +/- 18.3, and 0.22 +/- 0.01 for IPS e.max Press; 2.3 +/- 0.1, 83.5 +/- 15.0, and 0.21 +/- 0.01 for IPS e.max CAD; 2.5 +/- 0.1, 44.4 +/ 11.5, and 0.26 +/- 0.08 for PM9; 2.4 +/- 0.1, 70.6 +/- 4.9, and 0.22 +/- 0.01 for Vitamark II; 2.4 +/- 0.1, 63.3 +/- 3.9, and 0.23 +/- 0.01 for VM7, respectively. The 3D FEA showed the tensile stress at the interface between the tooth and the inlay was dependent on the elastic properties of the materials, since the Vita PM9 and IPS e.max CAD ceramics presented the lowest and the highest stress concentration in the interface, respectively. CONCLUSIONS: The elastic properties of ceramic materials were influenced by composition and processing methods, and these differences influenced the stress concentration at the bonding interface between tooth and restoration. The lower the elastic modulus of inlays, the lower is the stress concentration at the bonding interfaces. PMID- 27696616 TI - Diagnostic value of gadobutrol versus gadopentetate dimeglumine in enhanced MRI of brain metastases. AB - PURPOSE: To compare gadobutrol and gadopentetate dimeglumine (Gd-DTPA) contrast enhanced magnetic resonance imaging (MRI) at 3T for visualizing brain metastases. MATERIALS AND METHODS: The present randomized study included 60 consecutive patients with known or suspected brain metastases from systemic malignancies. Two enhanced cerebral MR scans were performed in each patient within an interval of 2 5 days using different contrast agents (gadobutrol or Gd-DTPA) at 3T. The dose of the contrast agents (0.1 mmol/kg Gd) was also identical. The axial T1 FLAIR images at 3, 7, and 10 minutes after the injection of the contrast agent were obtained for evaluation. Two experienced radiologists performed subjective evaluation of the image quality, made the choice of the optimal images, and performed an objective evaluation including: signal-to-noise ratio (SNR) of the brain metastases, contrast-to-noise ratio (CNR), contrast enhancement (CE), contrast-to-brain ratio (CBR), and contrast enhancement ratio (CER) of the brain metastases. RESULTS: Subjective evaluation showed that at 3, 7, and 10 minutes gadobutrol elicited higher scores (margin score: 3.56 +/- 0.74 vs. 3.33 +/- 0.93, 3.68 +/- 0.57 vs. 3.45 +/- 0.81, 3.58 +/- 0.71 vs. 3.43 +/- 0.76; interior score: 2.83 +/- 0.42 vs. 2.63 +/- 0.61, 2.86 +/- 0.38 vs. 2.73 +/- 0.52, 2.80 +/- 0.42 vs. 2.69 +/- 0.53; and overall score: 4.42 +/- 0.98 vs. 4.09 +/- 1.19, 4.57 +/- 0.75 vs. 4.26 +/- 1.05, 4.48 +/- 0.83 vs. 4.21 +/- 1.03, respectively) in displaying the details and overall lesions than Gd-DTPA (repeated measures analysis of variance [ANOVA], margin score: P = 0.001, < 0.0001, 0.006; interior score: P < 0.0001, 0.004, 0.009; and overall score: P = 0.001, < 0.0001, < 0.0001, respectively). Subjective optimal image evaluation showed that the percentage of image assessed as "gadobutrol was better than Gd-DTPA (41.2-44.1%)" was greater than that assessed as "Gd-DTPA was better than gadobutrol (5.9 26.5%)." Objective evaluation showed that at 3, 7, and 10 minutes the SNR (214.17 +/- 85.70 vs. 199.57 +/- 85.08, 214.80 +/- 86.03 vs. 199.19 +/- 84.74, and 213.83 +/- 82.46 vs. 193.68 +/- 79.59, respectively), CNR (68.64 +/- 50.18 vs. 57.88 +/- 51.06, 75.42 +/- 53.19 vs. 63.74 +/- 53.91, and 77.13 +/- 51.86 vs. 63.21 +/- 51.71, respectively), CE (101.76 +/- 63.31 vs. 87.61 +/- 64.85, 99.85 +/- 61.56 vs. 85.08 +/- 64.98, and 100.33 +/- 58.63 vs. 82.73 +/- 61.73, respectively), CBR (0.48 +/- 0.32 vs. 0.40 +/- 0.33, 0.54 +/- 0.34 vs. 0.46 +/- 0.35, and 0.56 +/- 0.34 vs. 0.47 +/- 0.34, respectively), and CER (0.99 +/- 0.69 vs. 0.88 +/- 0.81, 0.97 +/- 0.68 vs. 0.86 +/- 0.84, and 0.98 +/- 0.65 vs. 0.85 +/- 0.80, respectively) were all higher when using gadobutrol compared with Gd-DTPA in the enhanced MR (repeated measures ANOVA, all P < 0.0001). On Gd-DTPA enhanced images, 289, 292, and 292 lesions at 3, 7, and 10 minutes were detected by the two radiologists, while 295, 301, and 301 lesions were detected on gadobutrol enhanced images, respectively. CONCLUSION: Using a 3T T1 FLAIR sequence, gadobutrol (0.1 mmol/kg body weight)-enhanced MR resulted in more conspicuous brain metastases, and more metastases compared with the same dose of Gd-DTPA. A delay time of 7 minutes for postcontrast MRI in patients with brain metastases is suggested in clinical practice. LEVEL OF EVIDENCE: 2 J. MAGN. RESON. IMAGING 2017;45:1827-1834.

AB - Vasculogenesis is essential during early development to construct networks transporting oxygen, blood and nutrients. Tip and stalk cells are specialized endothelial cells involved in novel vessel formation because of their behavior such as sprouting as a leading cell and following tip cell. However, the spatiotemporal details determining the emergence of these cells are unknown. Here, we first show that the ERK activity in endothelial cells represents the precursor of tip and stalk cells for vasculogenesis in zebrafish. We identified that tip and stalk cells for intersegmental vessel (ISV) formation were already specialized in the dorsal aorta (DA) before sprouting. Furthermore, similar specialization was observed in tip cells during parachordal vessel (PAV) formation in lymphangiogenesis. We also identified that the ERK activity was required for specialized cells to emerge from existing blood vessels. Our data show that the ERK activity is a novel marker for determining the emergence of cells in both angiogenesis and lymphangiogenesis. PMID- 27696619 TI - Genotyping-by-sequencing approaches to characterize crop genomes: choosing the right tool for the right application. AB - In the last decade, the revolution in sequencing technologies has deeply impacted crop genotyping practice. New methods allowing rapid, high-throughput genotyping of entire crop populations have proliferated and opened the door to wider use of molecular tools in plant breeding. These new genotyping-by-sequencing (GBS) methods include over a dozen reduced-representation sequencing (RRS) approaches and at least four whole-genome resequencing (WGR) approaches. The diversity of methods available, each often producing different types of data at different cost, can make selection of the best-suited method seem a daunting task. We review the most common genotyping methods used today and compare their suitability for linkage mapping, genomewide association studies (GWAS), marker assisted and genomic selection and genome assembly and improvement in crops with various genome sizes and complexity. Furthermore, we give an outline of bioinformatics tools for analysis of genotyping data. WGR is well suited to genotyping biparental cross populations with complex, small- to moderate-sized genomes and provides the lowest cost per marker data point. RRS approaches differ in their suitability for various tasks, but demonstrate similar costs per marker data point. These approaches are generally better suited for de novo applications and more cost-effective when genotyping populations with large genomes or high heterozygosity. We expect that although RRS approaches will remain the most cost effective for some time, WGR will become more widespread for crop genotyping as sequencing costs continue to decrease. PMID- 27696622 TI - Virtue male sling for post-prostatectomy stress incontinence: a prospective evaluation and mid-term outcomes. AB - OBJECTIVE: To evaluate the efficacy and safety of the Virtue(r) male sling (Coloplast, Humlebaek, Denmark) in a cohort of patients affected by post prostatectomy stress urinary incontinence (SUI). METHODS: All 29 consecutive patients treated with a Virtue male sling at our Institution between July 2012 and October 2013 were included in the present prospective, non-randomized study. Patients were evaluated preoperatively and at 1, 3, 6, 12, 24 and 36 months after surgery using a 24-h pad weight test, the International Consultation on Incontinence short-form questionnaire (ICIQ-SF), Urinary Symptom Profile (USP) questionnaire, a bladder diary, uroflowmetry and the Patient Global Impression of Improvement (PGI-I) and Patient Global Impression of Severity questionnaires. RESULTS: The mean patient age was 65.5 years. A total of 72.4% of patients had preoperative mild incontinence (1-2 pads/day), while nine patients used 3-5 pads/day. There were a total of 17 complications, which occurred in 29 patients (58.6%); all were Clavien-Dindo grade I. At 12-month follow-up patients showed a significant improvement in 24-h pad test (128.6 vs 2.5 g), number of pads per day (2 vs 0), ICIQ-SF score (14.3 vs 0.9) and USP score for SUI (4 vs 0), and outcomes remained stable at 36 months. At last follow-up, the median score on the PGI-I questionnaire was 1 (very much better). CONCLUSION: The Virtue male sling is an effective treatment option for low to moderate post-prostatectomy incontinence. PMID- 27696623 TI - Novel insights into the composition and function of the Toxoplasma IMC sutures. AB - The Toxoplasma inner membrane complex (IMC) is a specialized organelle underlying the parasite's plasma membrane that consists of flattened rectangular membrane sacs that are sutured together and positioned atop a supportive cytoskeleton. We have previously identified a novel class of proteins localizing to the transverse and longitudinal sutures of the IMC, which we named IMC sutures components (ISCs). Here, we have used proximity-dependent biotin identification at the sutures to better define the composition of this IMC subcompartment. Using ISC4 as bait, we demonstrate biotin-dependent labeling of the sutures and have uncovered two new ISCs. We also identified five new proteins that exclusively localize to the transverse sutures that we named transverse sutures components (TSCs), demonstrating that components of the IMC sutures consist of two groups: those that localize to the transverse and longitudinal sutures (ISCs) and those residing only in the transverse sutures (TSCs). In addition, we functionally analyze the ISC protein ISC3 and demonstrate that ISC3-null parasites have morphological defects and reduced fitness in vitro. Most importantly, Deltaisc3 parasites exhibit a complete loss of virulence in vivo. These studies expand the known composition of the IMC sutures and highlight the contribution of ISCs to the ability of the parasite to proliferate and cause disease. PMID- 27696625 TI - Maternal zinc deficiency and congenital anomalies in newborns. AB - BACKGROUND: Zinc deficiency in pregnant women is common, especially in the third trimester of pregnancy. The available data, however, on the association between zinc deficiency and congenital malformations in the Iranian population are insufficient. The aim of this study was therefore to determine whether maternal serum zinc deficiency is associated with major congenital malformations in newborns. METHODS: This descriptive, case-control study involved mothers of 80 neonates with congenital anomalies (study group) admitted to the Mofid Children's Hospital, Tehran, Iran. During the same period (2014 and 2015), serum zinc was measured in 80 mothers who had delivered normal newborns without congenital malformations (control group). RESULTS: Mothers with serum zinc deficiency had a more than sevenfold risk of malformations in the fetus compared with mothers with normal serum zinc (OR, 7.013; 95%CI: 2.716-18.110). Newborns with malformation weighing <=2500 g were associated with lower maternal serum zinc compared with the control group (P = 0.006). CONCLUSIONS: There is an association between congenital malformation in newborns and maternal zinc deficiency. PMID- 27696624 TI - TAK1 maintains the survival of immunoglobulin lambda-chain-positive B cells. AB - TAK1 (MAP3K7) mediation of the IkappaB kinase (IKK) complex-nuclear factor-kappaB (NF-kappaB) pathway is crucial for the activation of immune response and to perpetuate inflammation. Although progress has been made to understand TAK1 function in the B-cell receptor (BCR) signaling, the physiological roles of TAK1 in B-cell development, particularly in the bone marrow (BM), remain elusive. Previous studies suggested that the IKK complex is required for the development of immunoglobulin light chain lambda-positive B cells, but not for receptor editing. In contrast, NF-kappaB activity is suggested to be involved in the regulation of receptor editing. Thus, NF-kappaB signaling in early B-cell development is yet to be fully characterized. Therefore, we addressed the role of TAK1 in early B-cell development. TAK1-deficient mice showed significant reduction of BM Iglambda-positive B-cell numbers without any alteration in the BCR editing. Furthermore, the expression of survival factor Bcl-2 was reduced in TAK1-deficient BM B cells as assessed by microarray and quantitative PCR analyses. Ex vivo over-expression of exogenous Bcl-2 enhanced the survival of TAK1-deficient Iglambda-positive B cells. TAK1-IKK-NF-kappaB signaling contributes to the survival of lambda-chain-positive B cells through NF-kappaB dependent anti-apoptotic Bcl-2 expression. PMID- 27696626 TI - Ubiquitin-proteasome-dependent degradation of TBP-like protein is prevented by direct binding of TFIIA. AB - Although the majority of gene expression is driven by TATA-binding protein (TBP) based transcription machinery, it has been reported that TBP-related factors (TRFs) are also involved in the regulation of gene expression. TBP-like protein (TLP), which is one of the TRFs and exhibits the highest affinity to TFIIA among known proteins, has recently been showed to have significant roles in gene regulation. However, how the level of TLP is maintained in vivo has remained unknown. In this study, we explored the mechanism by which TLP protein is turned over in vivo and the factor that maintains the amount of TLP. We showed that TLP is rapidly degraded by the ubiquitin-proteasome system and that tight interaction with TFIIA results in protection of TLP from ubiquitin-proteasome-dependent degradation. The half-life of TLP was shown to be less than a few hours, and the proteasome inhibitor MG132 specifically suppressed TLP degradation. Moreover, knockdown and over-expression experiments showed that TFIIA is engaged in stabilization of TLPin vivo. Thus, we showed a novel characteristic of TLP, that is, interaction with TFIIA is essential to suppress proteasome-dependent turnover of TLP, providing a further insight into TLP-governed gene regulation. PMID- 27696627 TI - Influenza A virus nucleoprotein targets subnuclear structures. AB - The Influenza A virus nucleoprotein (NP) is the major protein component of the genomic viral ribonucleoprotein (vRNP) complexes, which are the replication- and transcription-competent units of Influenza viruses. Early during infection, NP mediates import of vRNPs into the host cell nucleus where viral replication and transcription take place; also newly synthesized NP molecules are targeted into the nucleus, enabling coreplicational assembly of progeny vRNPs. NP reportedly acts as regulatory factor during infection, and it is known to be involved in numerous interactions with host cell proteins. Yet, the NP-host cell interplay is still poorly understood. Here, we report that NP significantly interacts with the nuclear compartment and displays distinct affinities for different subnuclear structures. NP subnuclear behavior was studied by expression of fluorescent NP fusion proteins - including obligate monomeric NP - and site-specific fluorescence photoactivation measurements. We found that NP constructs accumulate in subnuclear domains frequently found adjacent to or overlapping with promyelocytic leukemia bodies and Cajal bodies. Targeting of NP to Cajal bodies could further be demonstrated in the context of virus infection. We hypothesize that by targeting functional nuclear organization, NP might either link viral replication to specific cellular machinery or interfere with host cell processes. PMID- 27696628 TI - Reproducibility of high-definition (3D) manometry and its agreement with high resolution (2D) manometry in women with fecal incontinence. AB - BACKGROUND: While widely used in clinical practice, the reproducibility of high definition anorectal manometry (HD-ARM) remains unclear. We evaluated the intra individual reproducibility of HD-ARM and compared pressures measured with HD-ARM and high-resolution anorectal manometry (HR-ARM). METHODS: Thirty-six women with fecal incontinence had an initial HD-ARM (HD-ARM1); on the same day, after randomization, 21 had a second (HD-ARM2). Sixteen women had a third (HD-ARM3) 4 weeks later. Twenty-five had also been evaluated by HR-ARM previously. Rectoanal pressures were assessed at rest, during squeeze and simulated evacuation. Concordance among pressures was assessed with Lin's concordance correlation coefficient (CCC). KEY RESULTS: Anal resting and squeeze pressures measured with HD-ARM were reproducible on the same and different days; for average resting pressures of HD-ARM1 vs HD-ARM2, CCC = 0.73 (95% confidence interval [CI]: 0.53 0.94), and for HD-ARM1 vs HD-ARM3, CCC = 0.60 (95% CI: 0.28-0.93). For maximum squeeze pressures of HD-ARM1 vs HD-ARM2, CCC = 0.86 (95% CI: 0.75-0.97), and for HD-ARM1 vs HD-ARM3, CCC = 0.56 (95% CI: 0.21-0.91). The rectoanal gradient during evacuation was significantly concordant between HD-ARM1 and HD-ARM2 but not HD ARM1 and HD-ARM3. Resting (CCC = 0.38 [95% CI: 0.14-0.62]) and squeeze pressures (CCC = 0.73 [95% CI: 0.57-0.89]) measured with HD-ARM1 and HR-ARM were also concordant. CONCLUSIONS & INFERENCES: Among women with fecal incontinence, measurements with HD-ARM were reproducible on the same (anal resting and squeeze pressures and rectoanal gradient during evacuation) and different days (anal resting and squeeze pressures) and correlated with HR-ARM measurements. These findings support use of HD-ARM and HR-ARM for longitudinal assessments of anal resting and squeeze pressures. PMID- 27696629 TI - Association between HIV infection and socio-economic status: evidence from a semirural area of southern Mozambique. AB - OBJECTIVES: To analyse the association between socio-economic status (SES) and HIV in Manhica, a district of Southern Mozambique with one of the highest HIV prevalences in the world. METHODS: Data were gathered from two cross-sectional surveys performed in 2010 and 2012 among 1511 adults and from the household census of the district's population. Fractional polynomial logit models were used to analyse the association between HIV and SES, controlling for age and sex and taking into account the nonlinearity of covariates. The inequality of the distribution of HIV infection with regard to SES was computed through a concentration index. RESULTS: Fourth and fifth wealth quintiles, the least poor, were associated with a reduced probability of HIV infection compared to the first quintile (OR = 0.595, P-value = 0.009 and OR = 0.474, P-value < 0.001, respectively). Probability of HIV infection peaked at 36 years and then fell, and was always higher for women regardless of age and SES. HIV infection was unequally distributed across the SES strata. CONCLUSIONS: Despite the high HIV prevalence across the entire population of Manhica, the poorest are at greatest risk of being HIV infected. While women have a higher probability of being HIV positive than men, both sexes showed the same infection reduction at higher levels of SES. HIV interventions in the area should particularly focus on the poorest and on women without neglecting anyone else, as the HIV risk is high for everyone. PMID- 27696630 TI - Extracorporeal membrane oxygenation in 61 neonates: Single-center experience. AB - BACKGROUND: There have been few reports on the outcome of extracorporeal membrane oxygenation (ECMO) in newborn Japanese infants. METHODS: A review was carried out of 61 neonates with ECMO between January 1995 and December 2015 at a single center. ECMO was used in neonates with oxygenation index >20 after conventional treatment. Background factors, such as etiology, vascular access mode (veno venous [VV] or veno-arterial [VA]), number of days with ECMO, and early ECMO (within 24 h after birth), were analyzed in relation to outcome with respect to survival to hospital discharge (SHD). RESULTS: Survival to hospital discharge was achieved in 35 infants (57%), while the remaining 26 died during hospital stay. Gestational age at birth was significantly higher and number of days with ECMO was significantly lower in SHD infants compared with those with adverse outcome (median, 4.0 vs 5.5 days, respectively; P = 0.008). The SHD rate was significantly higher for those with VV than VA vascular access mode (78%, 18/23 vs 45%, 17/38, respectively; P = 0.016), and for those with than without early ECMO (72%, 28/39 vs 32%, 7/22, respectively; P = 0.003). The SHD rate was relatively high in neonates with meconium aspiration syndrome (86%, 12/14), persistent pulmonary hypertension associated with hypoxic ischemic encephalopathy (75%, 6/8), and emphysema (80%, 4/5). On stepwise logistic regression analysis two independent factors of SHD were identified: early ECMO (OR, 9.63; 95%CI: 2.47 37.6) and ECMO length <8 days (OR, 8.05; 95%CI: 1.94-33.5). CONCLUSIONS: Neonates with early ECMO and those with ECMO duration <8 days may benefit from ECMO with respect to SHD. PMID- 27696631 TI - Persistence of a dominant bovine lineage of group B Streptococcus reveals genomic signatures of host adaptation. AB - Group B Streptococcus (GBS) is a host-generalist species, most notably causing disease in humans and cattle. However, the differential adaptation of GBS to its two main hosts, and the risk of animal to human infection remain poorly understood. Despite improvements in control measures across Europe, GBS is still one of the main causative agents of bovine mastitis in Portugal. Here, by whole genome analysis of 150 bovine GBS isolates we discovered that a single CC61 clone is spreading throughout Portuguese herds since at least the early 1990s, having virtually replaced the previous GBS population. Mutations within an iron/manganese transporter were independently acquired by all of the CC61 isolates, underlining a key adaptive strategy to persist in the bovine host. Lateral transfer of bacteriocin production and antibiotic resistance genes also underscored the contribution of the microbial ecology and genetic pool within the bovine udder environment to the success of this clone. Compared to strains of human origin, GBS evolves twice as fast in bovines and undergoes recurrent pseudogenizations of human-adapted traits. Our work provides new insights into the potentially irreversible adaptation of GBS to the bovine environment. PMID- 27696632 TI - Ground transport stress affects bacteria in the rumen of beef cattle: A real-time PCR analysis. AB - Transport stress syndrome often appears in beef cattle during ground transportation, leading to changes in their capacity to digest food due to changes in rumen microbiota. The present study aimed to analyze bacteria before and after cattle transport. Eight Xianan beef cattle were transported over 1000 km. Rumen fluid and blood were sampled before and after transport. Real-time PCR was used to quantify rumen bacteria. Cortisol and adrenocorticotrophic hormone (ACTH) were measured. Cortisol and ACTH were increased on day 1 after transportation and decreased by day 3. Cellulolytic bacteria (Fibrobacter succinogenes and Ruminococcus flavefaciens), Ruminococcus amylophilus and Prevotella albensis were increased at 6 h and declined by 15 days after transport. There was a significant reduction in Succinivibrio dextrinosolvens, Prevotella bryantii, Prevotella ruminicola and Anaerovibrio lipolytica after transport. Rumen concentration of acetic acid increased after transport, while rumen pH and concentrations of propionic and butyric acids were decreased. Body weight decreased by 3 days and increased by 15 days after transportation. Using real-time PCR analysis, we detected changes in bacteria in the rumen of beef cattle after transport, which might affect the growth of cattle after transport.

AB - BACKGROUND AND PURPOSE: To investigate the efficacy of chiropractic spinal manipulative therapy (CSMT) for migraineurs. METHODS: This was a prospective three-armed, single-blinded, placebo, randomized controlled trial (RCT) of 17 months duration including 104 migraineurs with at least one migraine attack per month. The RCT was conducted at Akershus University Hospital, Oslo, Norway. Active treatment consisted of CSMT, whereas placebo was a sham push manoeuvre of the lateral edge of the scapula and/or the gluteal region. The control group continued their usual pharmacological management. The RCT consisted of a 1-month run-in, 3 months intervention and outcome measures at the end of the intervention and at 3, 6 and 12 months follow-up. The primary end-point was the number of migraine days per month, whereas secondary end-points were migraine duration, migraine intensity and headache index, and medicine consumption. RESULTS: Migraine days were significantly reduced within all three groups from baseline to post-treatment (P < 0.001). The effect continued in the CSMT and placebo group at all follow-up time points, whereas the control group returned to baseline. The reduction in migraine days was not significantly different between the groups (P > 0.025 for interaction). Migraine duration and headache index were reduced significantly more in the CSMT than the control group towards the end of follow up (P = 0.02 and P = 0.04 for interaction, respectively). Adverse events were few, mild and transient. Blinding was strongly sustained throughout the RCT. CONCLUSIONS: It is possible to conduct a manual-therapy RCT with concealed placebo. The effect of CSMT observed in our study is probably due to a placebo response. PMID- 27696634 TI - Physical activity and lung function decline in adults with asthma: The HUNT Study. AB - BACKGROUND AND OBJECTIVE: People with asthma may seek advice about physical activity. However, the benefits of leisure time physical activity on lung function are unclear. We investigated the association between leisure time physical activity and lung function decline in adults with asthma. METHODS: In a population-based cohort study in Norway, we used multiple linear regressions to estimate the annual mean decline in lung function (and 95% CI) in 1329 people with asthma over a mean follow-up of 11.6 years. The durations of light and hard physical activity per week in the last year were collected by questionnaire. Inactive participants did not report any light or hard activity, while active participants reported light or hard activity. RESULTS: The mean decline in forced expiratory volume in 1 s (FEV1 ) was 37 mL/year among inactive participants and 32 mL/year in active participants (difference: -5 mL/year (95% CI: -13 to 3)). The mean decline in forced vital capacity (FVC) was 33 mL/year among inactive participants and 31 mL/year in active participants (difference: -2 mL/year (95% CI: -11 to 7)). The mean decline in FEV1 /FVC ratio was 0.36%/year among inactive participants and 0.22%/year in active participants (difference: -0.14%/year (95% CI: -0.27 to -0.01)). The mean decline in peak expiratory flow (PEF) was 14 mL/year among the inactive participants and 10 mL/year in active participants (difference: -4 mL/year (95% CI: -9 to 1)). CONCLUSION: We observed slightly less decline in lung function in physically active than inactive participants with asthma, particularly for FEV1 , FEV1 /FVC ratio and PEF. PMID- 27696635 TI - Antiretroviral therapy status among people who died of AIDS-related causes from 2009 to 2013 in Brazil: a population-based study. AB - OBJECTIVE: To describe the antiretroviral therapy status of people living with HIV (PLHIV) who died of AIDS-related causes between 2009 and 2013. METHODS: We conducted a cross-sectional, population-based study. Data were obtained by linking the mortality information system and the national ART dispensing database. Trends were modelled using linear regression analysis. RESULTS: A total of 61 425 AIDS-related deaths were registered in Brazil between 2009 and 2013. Median age at death was 41 years (IQR: 33-49), and 65.7% (40 337) of deaths were among men; 47.2% (29 004) of PLHIV who died during the study period had never started treatment, 7.0% (4274) had discontinued it, 15.9% (9775) were on ART for 6 months or less and 29.9% (18 372) were on ART for more than 6 months. Only 1.3% of PLHIV were on third-line ARV regimens when they died. CONCLUSIONS: AIDS related mortality remains a challenge even in a context of sustained universal access to antiretroviral treatment due to failure of service provision, not to therapy failure. Robust health policies closing gaps in the HIV continuum of care are crucial to further reduce mortality. PMID- 27696636 TI - Intracellular amorphous carbonates uncover a new biomineralization process in eukaryotes. AB - Until now, descriptions of intracellular biomineralization of amorphous inclusions involving alkaline-earth metal (AEM) carbonates other than calcium have been confined exclusively to cyanobacteria (Couradeau et al., 2012). Here, we report the first evidence of the presence of intracellular amorphous granules of AEM carbonates (calcium, strontium, and barium) in unicellular eukaryotes. These inclusions, which we have named micropearls, show concentric and oscillatory zoning on a nanometric scale. They are widespread in certain eukaryote phytoplankters of Lake Geneva (Switzerland) and represent a previously unknown type of non-skeletal biomineralization, revealing an unexpected pathway in the geochemical cycle of AEMs. We have identified Tetraselmis cf. cordiformis (Chlorophyta, Prasinophyceae) as being responsible for the formation of one micropearl type containing strontium ([Ca,Sr]CO3 ), which we also found in a cultured strain of Tetraselmis cordiformis. A different flagellated eukaryotic cell forms barium-rich micropearls [(Ca,Ba)CO3 ]. The strontium and barium concentrations of both micropearl types are extremely high compared with the undersaturated water of Lake Geneva (the Ba/Ca ratio of the micropearls is up to 800,000 times higher than in the water). This can only be explained by a high biological pre-concentration of these elements. The particular characteristics of the micropearls, along with the presence of organic sulfur-containing compounds associated with and surrounding the micropearls-strongly suggest the existence of a yet-unreported intracellular biomineralization pathway in eukaryotic micro organisms. PMID- 27696638 TI - Comparing performance of 30-day readmission risk classifiers among hospitalized primary care patients. AB - RATIONALE, AIMS AND OBJECTIVES: Hospital readmission within 30 days of discharge occurs in almost 20% of US Medicare patients and may be a marker of poor quality inpatient care, ineffective hospital to home transitions, or disease severity. Within a patient centered medical home, care transition interventions may only be practical from cost and staffing perspectives if targeted at patients with the greatest risk of readmission. Various scoring algorithms attempt to predict patients at risk for 30-day readmission, but head-to-head comparison of performance is lacking. Compare published scoring algorithms which use generally available electronic medical record data on the same set of hospitalized primary care patients. METHODS: The LACE index, the LACE+ index, the HOSPITAL score, and the readmission risk score were computed on a consecutive cohort of 26,278 hospital admissions. Classifier performance was assessed by plotting receiver operating characteristic curves comparing the computed score with the actual outcome of death or readmission within 30 days. Statistical significance of differences in performance was assessed using bootstrapping techniques. RESULTS: Correct readmission classification on this cohort was moderate with the following c-statistics: Readmission risk score 0.666; LACE 0.680; LACE+ 0.662; and HOSPITAL 0.675. There was no statistically significant difference in performance between classifiers. CONCLUSIONS: Logistic regression based classifiers yield only moderate performance when utilized to predict 30-day readmissions. The task is difficult due to the variety of underlying causes for readmission, nonlinearity, and the arbitrary time period of concern. More sophisticated classification techniques may be necessary to increase performance and allow patient centered medical homes to effectively focus efforts to reduce readmissions.

AB - The metabolism in tumor cells shifts from oxidative phosphorylation to glycolysis even in an aerobic environment. This phenomenon is known as the Warburg effect. This effect is regulated mainly by polypyrimidine tract-binding protein 1 (PTBP1), which is a splicer of the mRNA for the rate-limiting enzymes of glycolysis, pyruvate kinase muscle 1 and 2 (PKM1 and PKM2). In the present study, we demonstrated that miR-133b reduced PTBP1 expression at translational level and that the expression levels of miR-133b were significantly downregulated in gastric cancer clinical samples and human cell lines, whereas the protein expression level of PTBP1 was upregulated in 80% of the 20 clinical samples of gastric cancer examined. Ectopic expression of miR-133b and knockdown of PTBP1 in gastric cancer cells inhibited cell proliferation through the induction of autophagy by the switching of PKM isoform expression from PKM2-dominant to PKM1 dominant. The growth inhibition was partially canceled by an autophagy inhibitor 3-MA or a reactive oxygen species scavenger N-acetylcysteine. These findings indicated that miR-133b acted as a tumor-suppressor through negative regulation of the Warburg effect in gastric cancer cells. PMID- 27696639 TI - Label-free identification of antibiotic resistant isolates of living Escherichia coli: Pilot study. AB - We introduce a label-free spectroscopic method to classify subtypes of quinolone nonsusceptible Escherichia coli (E. coli) isolates obtained from human blood cultures. Raman spectroscopy with a 30-nm gold-deposited, surface-enhanced Raman scattering (SERS) substrate was used to evaluate three multilocus sequencing typing (MLST)-predefined groups including E. coli ATCC25922, E. coli ST131:O75, and E. coli ST1193:O25b. Although there was a coffee-ring effect, the ring zone was selected at the ideal position to screen E. coli isolates. Strong Raman peaks were present at 1001-1004 cm-1 (C?C aromatic ring breathing stretching vibrational mode of phenylalanine), 1447-1448 cm-1 (C?H2 scissoring deformation vibrational mode), and 1667 cm-1 (amide I alpha-helix). Although the three MLST predefined E. coli isolates had similar Raman spectral patterns, a support vector machine (SVM) learning algorithm-assisted principal component analysis (PCA) analysis had superior performance in detecting the presence of quinolone nonsusceptible E. coli isolates as well as classifying similar microbes, such as quinolone-nonsusceptible E. coli ST131:O75 and E. coli ST1193:O25b isolates. Therefore, this label-free and nondestructive technique is likely to be useful for clinically diagnosing quinolone-nonsusceptible E. coli isolates with the MLST method. PMID- 27696640 TI - Assessing the multiscale architecture of muscular tissue with Q-space magnetic resonance imaging: Review. AB - Contraction of muscular tissue requires the synchronized shortening of myofibers arrayed in complex geometrical patterns. Imaging such myofiber patterns with diffusion-weighted MRI reveals architectural ensembles that underlie force generation at the organ scale. Restricted proton diffusion is a stochastic process resulting from random translational motion that may be used to probe the directionality of myofibers in whole tissue. During diffusion-weighted MRI, magnetic field gradients are applied to determine the directional dependence of proton diffusion through the analysis of a diffusional probability distribution function (PDF). The directions of principal (maximal) diffusion within the PDF are associated with similarly aligned diffusion maxima in adjacent voxels to derive multivoxel tracts. Diffusion-weighted MRI with tractography thus constitutes a multiscale method for depicting patterns of cellular organization within biological tissues. We provide in this review, details of the method by which generalized Q-space imaging is used to interrogate multidimensional diffusion space, and thereby to infer the organization of muscular tissue. Q space imaging derives the lowest possible angular separation of diffusion maxima by optimizing the conditions by which magnetic field gradients are applied to a given tissue. To illustrate, we present the methods and applications associated with Q-space imaging of the multiscale myoarchitecture associated with the human and rodent tongues. These representations emphasize the intricate and continuous nature of muscle fiber organization and suggest a method to depict structural "blueprints" for skeletal and cardiac muscle tissue. PMID- 27696641 TI - A social-technological epistemology of clinical decision-making as mediated by imaging. AB - In recent years there has been growing attention to the epistemology of clinical decision-making, but most studies have taken the individual physicians as the central object of analysis. In this paper we argue that knowing in current medical practice has an inherently social character and that imaging plays a mediating role in these practices. We have analyzed clinical decision-making within a medical expert team involved in diagnosis and treatment of patients with pulmonary hypertension (PH), a rare disease requiring multidisciplinary team involvement in diagnosis and management. Within our field study, we conducted observations, interviews, video tasks, and a panel discussion. Decision-making in the PH clinic involves combining evidence from heterogeneous sources into a cohesive framing of a patient, in which interpretations of the different sources can be made consistent with each other. Because pieces of evidence are generated by people with different expertise and interpretation and adjustments take place in interaction between different experts, we argue that this process is socially distributed. Multidisciplinary team meetings are an important place where information is shared, discussed, interpreted, and adjusted, allowing for a collective way of seeing and a shared language to be developed. We demonstrate this with an example of image processing in the PH service, an instance in which knowledge is distributed over multiple people who play a crucial role in generating an evaluation of right heart function. Finally, we argue that images fulfill a mediating role in distributed knowing in 3 ways: first, as enablers or tools in acquiring information; second, as communication facilitators; and third, as pervasively framing the epistemic domain. With this study of clinical decision making in diagnosis and treatment of PH, we have shown that clinical decision making is highly social and mediated by technologies. The epistemology of clinical decision-making needs to take social and technological mediation into account. PMID- 27696643 TI - Genomic diversification of marine cyanophages into stable ecotypes. AB - Understanding the structure and origin of natural bacteriophage genomic diversity is important in elucidating how bacteriophages influence the mortality rates and composition of their host communities. Here, we examine the genetic structure and genomic diversification of naturally occurring bacteriophages by analyzing the full genomic sequences of over 100 isolates of Synechococcus-infecting cyanophages collected over 15 years from coastal waters of Southern New England, USA. Our analysis revealed well-supported cyanophage genomic clusters (genome wide average nucleotide identity (ANI) >93%) and subclusters (genome-wide ANI >98%) that remained consistent for a decade or longer. Furthermore, by combining the genomic data with genetic analysis of an additional 800 isolates and environmental amplicon sequence data both genomic clusters and subclusters were found to exhibit clear temporal and/or spatial patterns of abundance, suggesting that these units represent distinct viral ecotypes. The processes responsible for diversification of cyanophages into genomic clusters and subclusters were similar across genetic scales and included allelic exchange as well as gene gain and loss. Isolates belonging to different subclusters were found to differ in genes that encoded auxiliary metabolic functions, restriction modification enzymes, and virion structural proteins, although the specific traits and selection pressures responsible for the maintenance of distinct ecotypes remain unknown. PMID- 27696642 TI - Partially methylated alleles, microdeletion, and tissue mosaicism in a fragile X male with tremor and ataxia at 30 years of age: A case report. AB - CGG repeat expansion >200 within FMR1, termed full mutation (FM), has been associated with promoter methylation, consequent silencing of gene expression and fragile X syndrome (FXS)-a common cause of intellectual disability and co-morbid autism. Unmethylated premutation (55-199 repeats) and FM alleles have been associated with fragile X related tremor/ataxia syndrome (FXTAS), a late onset neurodegenerative disorder. Here we present a 33-year-old male with FXS, with white matter changes and progressive deterioration in gait with cerebellar signs consistent with probable FXTAS; there was no evidence of any other cerebellar pathology. We show that he has tissue mosaicism in blood, saliva, and buccal samples for the size and methylation of his expanded alleles and a de novo, unmethylated microdeletion. This microdeletion involves a ~80 bp sequence in the FMR1 promoter as well as complete loss of the CGG repeat in a proportion of cells. Despite FMR1 mRNA levels in blood within the normal range, the methylation and CGG sizing results are consistent with the diagnosis of concurrent FXS and probable FXTAS. The demonstrated presence of unmethylated FM alleles would explain the manifestation of milder than expected cognitive and behavioral impairments and early onset of cerebellar ataxia. Our case suggests that individuals with FXS, who manifest symptoms of FXTAS, may benefit from more detailed laboratory testing. (c) 2016 Wiley Periodicals, Inc.

PMID- 27696645 TI - Sensitivity of Fusarium culmorum to triazoles: impact of trichothecene chemotypes, oxidative stress response and genetic diversity. AB - BACKGROUND: Fusarium culmorum is a fungal pathogen occurring worldwide on various weeds and important crops. Triazoles have been shown to be the most effective fungicide for managing Fusarium spp., but little is known about their specific activity on F. culmorum. RESULTS: The sensitivity of 107 F. culmorum strains to triazoles was assessed using microtitre plate assays. The EC50 values ranged from 0.14 to 1.53 mg L-1 for tebuconazole and from 0.25 to 2.47 mg L-1 for epoxiconazole. Cross-resistance to both azoles was found (r = 0.61). F. culmorum appeared to be significantly more sensitive than F. graminearum or F. cerealis. No increase in the mean EC50 was observed over time, which might be related to an unfavourable fitness cost, measured here as fungal growth. On average, nivalenol producing strains of F. culmorum were significantly more resistant than deoxynivalenol-producing strains. The relationship between resistance and chemotype-dependent adaptation to oxidative stress was investigated, but remained unclear. No link between inter-simple sequence repeat (ISSR) genetic diversity and triazole resistance could be established. CONCLUSION: Fungicide use might not be a driving force in the evolution of F. culmorum, and the benefit of a resistance trait probably does not outweigh its costs.

AB - Dietary changes are known to affect gut community structure, but questions remain about the mechanisms by which diet induces shifts in microbiome membership. Here, we addressed these questions in the rumen microbiome ecosystem - a complex microbial community that resides in the upper digestive tract of ruminant animals and is responsible for the degradation of the ingested plant material. Our dietary intervention experiments revealed that diet affects the most abundant taxa within the microbiome and that a specific group of methanogenic archaea of the order Methanomicrobiales is highly sensitive to its changes. Using metabolomic analyses together with in vitro microbiology approaches and whole genome sequencing of Methanomicrobium mobile, a key species within this group, we identified that redox potential changes with diet and is the main factor that causes these dietary induced alternations in this taxa's abundance. Our genomic analysis suggests that the redox potential effect stems from a reduced number of anti-reactive oxygen species proteins coded in this taxon's genome. Our study highlights redox potential as a pivotal factor that could serve as a sculpturing force of community assembly within anaerobic gut microbial communities. PMID- 27696647 TI - Ecological and genetic determinants of plasmid distribution in Escherichia coli. AB - Bacterial plasmids are important carriers of virulence and antibiotic resistance genes. Nevertheless, little is known of the determinants of plasmid distribution in bacterial populations. Here the factors affecting the diversity and distribution of the large plasmids of Escherichia coli were explored in cattle grazing on semi-natural grassland, a set of populations with low frequencies of antibiotic resistance genes. Critically, the population genetic structure of bacterial hosts was chararacterized. This revealed structured E. coli populations with high diversity between sites and individuals but low diversity within cattle hosts. Plasmid profiles, however, varied considerably within the same E. coli genotype. Both ecological and genetic factors affected plasmid distribution: plasmid profiles were affected by site, E. coli diversity, E. coli genotype and the presence of other large plasmids. Notably 3/26 E. coli serotypes accounted for half the observed plasmid-free isolates indicating that within species variation can substantially affect carriage of the major conjugative plasmids. The observed population structure suggest that most of the opportunities for within species plasmid transfer occur between different individuals of the same genotype and support recent experimental work indicating that plasmid-host coevolution, and epistatic interactions on fitness costs are likely to be important in determining occupancy. PMID- 27696649 TI - Functional analysis of Escherichia coli Yad fimbriae reveals their potential role in environmental persistence. AB - Initial adhesion of bacterial cells to surfaces or host tissues is a key step in colonisation and biofilm formation processes, and is mediated by cell surface appendages. It was previously demonstrated that Escherichia coli K-12 possesses an arsenal of silenced chaperone-usher fimbriae that were functional when constitutively expressed. Among them, production of prevalent Yad fimbriae induces adhesion to abiotic surfaces. Functional characterisation of Yad fimbriae were undertook, and YadN was identified as the most abundant and potential major pilin, and YadC as the potential tip-protein of Yad fimbriae. It was showed that Yad production participates to binding of E. coli K-12 to human eukaryotic cells (Caco-2) and inhibits macrophage phagocytosis, but also enhances E. coli K-12 binding to xylose, a major component of the plant cell wall, through its tip lectin YadC. Consistently, it was demonstrated that Yad production provides E. coli with a competitive advantage in colonising corn seed rhizospheres. The latter phenotype is correlated with induction of Yad expression at temperatures below 37 degrees C, and under anaerobic conditions, through a complex regulatory network. Taken together, these results suggest that Yad fimbriae are versatile adhesins that beyond potential capacities to modulate host-pathogen interactions might contribute to E. coli environmental persistence.

AB - A 59-year-old patient with multiple myeloma on maintenance chemotherapy presented with fever, weight loss, and night sweats. An F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) computed tomography (CT) showed intra abdominal lymphadenopathy with a mesenteric mass that led to further workup and diagnosis of histoplamosis. The patient was treated with amphotericin B and subsequently switched to itraconazole. This exemplifies the usefulness of FDG PET CT in diagnosis of infectious complications. PMID- 27696650 TI - Transcatheter aortic valve implantation in degenerative sutureless perceval aortic bioprosthesis. AB - Sutureless aortic bioprostheses (SAB) are increasingly being used to provide shorter cross-clamp time. Valve-in-valve transcatheter aortic valve replacement (VIV-A) is shown to be effective and safe in the vast majority of patients with degenerated bioprosthetics, yet its' use in SAB failure is infrequent. We present a case of balloon-expandable VIV-A in an 80-year-old woman who suffered severe symptomatic aortic regurgitation in a failed Perceval S 21-mm valve. Computed tomography scan demonstrated a deformed valve. Our heart team favored a percutaneous VIV-A over reoperation due to the patients' high surgical risk. An Edwards-Sapien XT 23 mm was successfully deployed with excellent results. The patient remained asymptomatic following 6 months. As other bioprosthesis, some sutureless valves are condemned to structural valve degeneration. Because VIV-A is being established for managing degenerative bioprosthesis in high risk patients, it is cardinal to identify its role in novel degenerative sutureless valves. SAB were introduced to the clinical market only 5-7 years ago. The absence of sutures may theoretically impose risk for valve instability when adding a transcatheter sutureless valve inside the first one. Our successful experience was very reassuring. We report its feasibility because we believe it should provide support for further investigation on VIV-A within novel SAV. (c) 2016 Wiley Periodicals, Inc. PMID- 27696652 TI - Urinary collecting system invasion is associated with poor survival in patients with clear-cell renal cell carcinoma. AB - OBJECTIVES: To evaluate the prognostic significance of urinary collecting system invasion (UCSI) in a large series of patients with clear-cell renal cell carcinoma (RCC). MATERIALS AND METHODS: Patients with clear-cell RCC treated with nephrectomy between 2001 and 2010 were reviewed from a prospectively maintained registry. One urological pathologist re-reviewed all slides. Cancer-specific survival was estimated using the Kaplan-Meier method, and associations of UCSI with death from RCC were evaluated using Cox models. RESULTS: Of the 859 patients with clear-cell RCC, 58 (6.8%) had UCSI. At last follow-up, 310 patients had died from RCC at a median of 1.8 years after surgery. The median follow-up for patients alive at last follow-up was 8.2 years. The estimated cancer-specific survival at 10 years after surgery for patients with UCSI was 17%, compared with 60% for patients without UCSI (P < 0.001). In a multivariable model, UCSI remained independently associated with an increased risk of death from RCC (hazard ratio 1.5; P = 0.018). Further, among patients with pT3 RCC, those with USCI had survival outcomes similar to those of patients with pT4 RCC. CONCLUSIONS: Collecting system invasion is associated with poor prognosis among patients with clear-cell RCC. If validated, consideration should be given to including UCSI in future staging systems. PMID- 27696653 TI - Virology analyses of HCV genotype 4 isolates from patients treated with simeprevir and peginterferon/ribavirin in the Phase III RESTORE study. AB - Simeprevir is a hepatitis C virus NS3/4A protease inhibitor. Hepatitis C virus baseline NS3/4A polymorphisms and emerging mutations were characterized in treatment-naive and treatment-experienced genotype 4-infected patients treated with simeprevir+peginterferon/ribavirin in the RESTORE study. Population sequencing of the NS3/4A region was performed and in vitro simeprevir activity against site-directed mutants or chimeric replicons with patient-derived NS3 protease sequences was assessed in a transient replicon assay. Simeprevir remained active against most (83/91 [91%]) baseline isolates tested in the chimeric replicon assay. Eight baseline isolates reduced simeprevir activity; these carried I132L or D168E substitutions reducing simeprevir median activity by 4.6- and 39-fold, respectively. Six of these eight isolates were from patients achieving sustained virologic response. Baseline NS3 Q80K polymorphism was not observed in the genotype 4-infected patients. Of the 107 simeprevir-treated patients, 37 did not achieve sustained virologic response for any reason. Of the 32 patients who failed treatment and had sequencing information, 28 (88%) had emerging mutations at NS3 positions 80, 122, 155, 156 and/or 168 at time of failure, similar to those in genotype 1. Emerging mutations were mainly D168V and D168E alone or combined with mutations at position 80. In general, isolates obtained at time of failure displayed high-level in vitro resistance to simeprevir (fold change >=50) in a chimeric replicon assay with a median simeprevir fold change value of 440, consistent with observed mutations. In conclusion, emerging mutations in genotype 4 patients failing simeprevir+peginterferon/ribavirin treatment were similar to those in genotype 1 and conferred high-level resistance to simeprevir. PMID- 27696651 TI - An evolutionary balance: conservation vs innovation in ciliate membrane trafficking. AB - As most of eukaryotic diversity lies in single-celled protists, they represent unique opportunities to ask questions about the balance of conservation and innovation in cell biological features. Among free-living protists the ciliates offer ease of culturing, a rich array of experimental approaches, and versatile molecular tools, particularly in Tetrahymena thermophila and Paramecium tetraurelia. These attributes have been exploited by researchers to analyze a wealth of cellular structures in these large and complex cells. This mini-review focuses on 3 aspects of ciliate membrane dynamics, all linked with endolysosomal trafficking. First is nutrition based on phagocytosis and maturation of food vacuoles. Secondly, we discuss regulated exocytosis from vesicles that have features of both dense core secretory granules but also lysosome-related organelles. The third topic is the targeting, breakdown and resorption of parental nuclei in mating partners. For all 3 phenomena, it is clear that elements of the canonical membrane-trafficking system have been retained and in some cases repurposed. In addition, there is evidence that recently evolved, lineage-specific proteins provide determinants in these pathways.

AB - We analysed N2 - and carbon (C) fixation in individual cells of Baltic Sea cyanobacteria by combining stable isotope incubations with secondary ion mass spectrometry (SIMS). Specific growth rates based on N2 - and C-fixation were higher for cells of Dolichospermum spp. than for Aphanizomenon sp. and Nodularia spumigena. The cyanobacterial biomass, however, was dominated by Aphanizomenon sp., which contributed most to total N2 -fixation in surface waters of the Northern Baltic Proper. N2 -fixation by Pseudanabaena sp. and colonial picocyanobacteria was not detectable. N2 -fixation by Aphanizomenon sp., Dolichospermum spp. and N. spumigena populations summed up to total N2 -fixation, thus these genera appeared as sole diazotrophs within the Baltic Sea's euphotic zone, while their mean contribution to total C-fixation was 21%. Intriguingly, cell-specific N2 -fixation was eightfold higher at a coastal station compared to an offshore station, revealing coastal zones as habitats with substantial N2 fixation. At the coastal station, the cell-specific C- to N2 -fixation ratio was below the cellular C:N ratio, i.e. N2 was assimilated in excess to C-fixation, whereas the C- to N2 -fixation ratio exceeded the C:N ratio in offshore sampled diazotrophs. Our findings highlight SIMS as a powerful tool not only for qualitative but also for quantitative N2 -fixation assays in aquatic environments. PMID- 27696655 TI - Coprinuslactone protects the edible mushroom Coprinus comatus against biofilm infections by blocking both quorum-sensing and MurA. AB - Pathogens embedded in biofilms are involved in many infections and are very difficult to treat with antibiotics because of higher resistance compared with planktonic cells. Therefore, new approaches for their control are urgently needed. One way to search for biofilm dispersing compounds is to look at defense strategies of organisms exposed to wet environments, which makes them prone to biofilm infections. It is reasonable to assume that mushrooms have developed mechanisms to control biofilms on their sporocarps (fruiting bodies). A preliminary screening for biofilms on sporocarps revealed several species with few or no bacteria on their sporocarps. From the edible mushroom Coprinus comatus where no bacteria on the sporocarp could be detected (3R,4S)-2-methylene-3,4 dihydroxypentanoic acid 1,4-lactone, named coprinuslactone, was isolated. Coprinuslactone interfered with quorum-sensing and dispersed biofilms of Pseudomonas aeruginosa, where it also reduced the formation of the pathogenicity factors pyocyanin and rhamnolipid B. Coprinuslactone also damaged Staphylococcus aureus cells in biofilms at subtoxic concentrations. Furthermore, it inhibited UDP-N-acetylglucosamine enolpyruvyl transferase (MurA), essential for bacterial cell wall synthesis. These two modes of action ensure the inhibition of a broad spectrum of pathogens on the fruiting body but may also be useful for future clinical applications.

AB - BACKGROUND: Reinduction therapy has improved the outcomes in children with acute lymphoblastic leukemia (ALL). We sought to determine the optimal course(s) of reinduction therapy for standard-risk (SR, or "low-risk" in other groups) patients. Also, we evaluated outcomes using triple intrathecal therapy without cranial radiation (CrRT) for central nervous system (CNS) preventive therapy. PROCEDURE: From 2002 to 2012, all newly diagnosed children with ALL in Taiwan were enrolled in Taiwan Pediatric Oncology Group ALL-2002 protocol. SR patients were randomized to receive single or double reinduction courses. The patients enrolled before 2009 received CrRT, while those enrolled later did not. The Kaplan-Meier method was used to estimate survival rates and the difference between two groups was compared by the two-sided log-rank test. RESULTS: In 1,366 eligible patients, the 5-year overall survival (OS) was 81.6 +/- 1.1% (standard error) and 5-year event-free survival (EFS) was 74.3 +/- 1.2%. In SR patients, the 5-year OS for one and two reinduction courses was 91.6 +/- 2.1% and 93.7 +/- 1.8%, respectively, and the 5-year EFS was 85.2 +/- 2.7% and 89.8 +/- 2.3%, respectively. There were no significant differences in survival between these two groups. Patients with MLL or BCR-ABL1 had the worst outcomes: 5-year EFS was 23.4 and 31.8% and 5-year OS was 28.6 and 44.7%, respectively. There was no significant difference in CNS relapse or survival between the era with or without CrRT. CONCLUSIONS: For SR patients, one-course reinduction was adequate. Triple intrathecal therapy alone successfully prevented CNS relapse.

AB - Evidence supports the establishment of healthy feeding practices early in life to promote lifelong healthy eating patterns protective against chronic disease such as obesity. Current early childhood obesity prevention interventions are built on extant understandings of how feeding practices relate to infant's cues of hunger and satiety. Further insights regarding factors that influence feeding behaviors in early life may improve program designs and outcomes. Four electronic databases were searched for peer-reviewed qualitative studies published between 2000 to 2014 with transitional infant feeding practice rationale from developed countries. Reporting transparency and potential bias was assessed using the Consolidated Criteria for Reporting Qualitative Research quality checklist. Thematic synthesis of 23 manuscripts identified three themes (and six sub themes): Theme 1. Infant (physical cues and behavioural cues) focuses on the perceived signs of readiness to start solids and the feeding to influence growth and "health happiness." Theme 2. Mother (coping strategies and knowledge and skills) focuses on the early survival of the infant and the family and the feeding to satisfy hunger and influence infant contentment, and sleep. Theme 3. Community (pressure and inconsistent advice) highlights the importance of generational feeding and how conflicting feeding advice led many mothers to adopt valued familial or culturally established practices. Overall, mothers were pivotal to feeding decisions. Satisfying infant's needs to reach "good mothering" status as measured by societal expectations was highly valued but lacked consideration of nutrition, obesity, and long term health. Maternal interpretation of healthy infant feeding and successful parenting need attention when developing strategies to support new families. PMID- 27696657 TI - Depressive symptoms modify age effects on hippocampal subfields in older adults. AB - AIM: Major depression is associated with hippocampal volume changes, especially in late-life depression. These changes usually consist of volume reductions, but depression-related increases in hippocampal volume have also been reported. Subfield analysis has identified structural changes primarily in the cornu ammonis (CA) 1, CA2-3 and subiculum of the hippocampus in individuals with major depression; however, it is unclear whether lower levels of depressive symptoms are also associated volume reduction, or if depressive symptoms interact with age to impact hippocampal subfields. The current study addressed these questions. METHODS: A total of 43 community-dwelling older adults completed the Center for Epidemiologic Studies Depression Scale and underwent magnetic resonance imaging. Hippocampal subfield segmentation was carried out using an automated procedure, and left and right volumes from CA1, CA2-3, and the subiculum served as outcome measures. Multiple hierarchical regressions were carried out with age, Center for Epidemiologic Studies Depression Scale scores and their interaction as the independent variables, and sex and total intracranial volume as covariates. RESULTS: Higher Center for Epidemiologic Studies Depression Scale scores were associated with less age-related volumetric decreases in the right subiculum and right CA1. CONCLUSIONS: Age-related atrophy in the hippocampus might be counteracted by depressive symptom-related enlargement of CA1 and the subiculum. More research is required to better understand the functional significance of this relationship. Geriatr Gerontol Int 2017; 17: 1494-1500. PMID- 27696659 TI - Transcatheter aortic valve implantation with a Sapien 3 Commander 20 mm valves in patients with degenerated 19 mm bioprosthetic aortic valve. AB - INTRODUCTION: Transcatheter aortic valve implantation (TAVI) in patients with degenerated bioprosthetic aortic valve has been successfully performed as an alternative to surgery. We describe our initial experience of valve-in-valve TAVI in five patients, using new generation Edwards Sapien 3 transcatheter heart valves implanted into degenerated 19 mm bioprosthetic valves. 20-mm Edwards S3 valves were offered for compassionate use. All patients had significant aortic valve stenosis. METHODS AND RESULTS: The main vascular access was achieved and pre-closed with two Proglide closure devices in one patient and Prostar closure devices in four patients. For each TAVI procedure an Edwards 14 French sheath was inserted without complication and sutured in place. The Sapien 3 Commander delivery system was inserted and the valve was aligned in the descending aorta. The 20-mm Sapien 3 valve was deployed with slow continuous inflation during rapid right ventricular pacing. The cranial edge of the Edwards S3 valve was aligned with the cranial radiopaque markers of bioprosthesis to minimize paravalvular leak. Post-deployment angiography, transesophageal echocardiography and aortogram confirmed absence of mild aortic insufficiency and no increase in trans-aortic gradient when compared to a naive 19 mm bioprosthetic valve. CONCLUSION: Valve-in valve TAVI with the Edwards S3 transcatheter heart valve for degenerative bioprosthetic aortic valves is technically feasible. The proper position of the stented valve minimizes the risk for post-procedure paravalvular insufficiency and provides good transaortic pressure gradient. (c) 2016 Wiley Periodicals, Inc.

AB - A series of 3-(substituted aroyl)-4-(3,4,5-trimethoxyphenyl)-1H-pyrrole derivatives were synthesized and determined for their anticancer activity against eleven cancer cell lines and two normal tissue cell lines using MTT assay. Among the synthesized compounds, compound 3f was the most potent compound against A375, CT-26, HeLa, MGC80-3, NCI-H460 and SGC-7901 cells (IC50 = 8.2 - 31.7 MUm); 3g, 3n and 3a were the most potent compounds against CHO (IC50 = 8.2 MUm), HCT-15 (IC50 = 21 MUm) and MCF-7 cells (IC50 = 18.7 MUm), respectively. Importantly, all the target compounds showed no cytotoxicity towards the normal tissue cell (IC50 > 100 MUm). Thus, these compounds with the potent anticancer activity and low toxicity have potential for the development of new anticancer chemotherapy agents.

AB - Delayed graft function is a frequent complication following deceased donor renal transplantation, and is closely related to ischemia-reperfusion injury. Experimental and clinical studies have shown protection by remote ischemic conditioning (RIC). We hypothesized that recipient RIC before kidney graft reperfusion reduces the time to graft recovery. This multicenter, blinded, randomized, controlled clinical trial included 225 adult recipients of renal transplants from deceased donors at four transplantation centers in Denmark, Sweden, and the Netherlands. Participants were randomized 1:1 to RIC or sham-RIC. RIC consisted of 4 * 5-min thigh occlusion by an inflatable tourniquet each followed by 5-min deflation, performed during surgery prior to graft reperfusion. The tourniquet remained deflated for sham-RIC. The primary endpoint was the estimated time to a 50% decrease in baseline plasma creatinine (tCr50) calculated from plasma creatinine measurements 30 days posttransplant or 30 days after the last, posttransplant dialysis. No significant differences were observed between RIC and sham-RIC-treated patients in the primary outcome median tCr50 (122 h [95% confidence interval [CI] 98-151] vs. 112 h [95% CI 91-139], p = 0.58), or the number of patients receiving dialysis in the first posttransplant week (33% vs. 35%, p = 0.71). Recipient RIC does not reduce the time to graft recovery in kidney transplantation from deceased donors. ClinicalTrials.gov: NCT01395719.

AB - The Say-Barber-Biesecker-Young-Simpson variant of Ohdo syndrome (SBBYSS) (MIM# 603736) and genitopatellar syndrome (GPS) (MIM#606170) are allelic diseases caused by KAT6B mutation. Genotype-phenotype correlation is assumed, but a few patients manifest overlapping features of both syndromes. Here we report the case of a boy with SBBYSS. He had a KAT6B mutation previously reported in typical SBBYSS, but he also manifested severe developmental delay, as well as genital features and laryngomalacia requiring tracheostomy that conformed to GPS. PMID- 27696665 TI - A mechanism for stroke complicating thrombus aspiration. AB - We propose a mechanism of how stroke may be caused by thrombus aspiration during primary percutaneous coronary intervention (PPCI), and how it may be technique dependent. Two recent meta-analyses report increased risk of stroke in patients undergoing routine thrombus aspiration during STEMI and the value of this technique has been controversial. The mechanism of stroke has not been fully explained. This case demonstrates 2 mechanisms by which aspiration might cause thrombus embolization. We recommend that if thrombus aspiration is performed during PPCI for STEMI, it should be done selectively and carefully. It is prudent to make sure the guide catheter tip is not free in the aorta when the aspiration catheter is withdrawn, to maintain suction on the aspiration catheter as it is withdrawn (particularly if the aspiration port seems to be obstructed), and to aspirate the guide catheter after the aspiration catheter is removed to capture any fragments of thrombus that remain in the guide catheter.

AB - Wnt genes are a family of conserved glycoprotein ligands that play a role in a wide variety of cell and developmental processes, from cell proliferation to axis elongation. There are 13 Wnt subfamilies found among metazoans. Eleven of these appear conserved in arthropods with a pattern of loss during evolution of as many as six subfamilies among hexapods. Here we report on Wnt genes in the branchiopod crustacean, Thamnocephalus platyurus, including the first documentation of the expression of the complete Wnt gene family in a crustacean. Our results suggest fewer Wnt genes were retained in Thamnocephalus than in the related crustacean, Daphnia, although the Thamnocephalus Wnt repertoire is larger than that found in insects. We also find an intriguing pattern of staggered expression of Wnts-an anterior-posterior stagger within the posterior growth zone and a dorsal-ventral stagger in the developing segments-suggesting a potential for subfunctionalization of Wnts in these regions. PMID- 27696667 TI - The anti-ageing hormone klotho induces Nrf2-mediated antioxidant defences in human aortic smooth muscle cells. AB - Vascular ageing in conditions such as atherosclerosis, diabetes and chronic kidney disease, is associated with the activation of the renin angiotensin system (RAS) and diminished expression of antioxidant defences mediated by the transcription factor nuclear factor erythroid 2-related factor 2 (Nrf2). The anti ageing hormone klotho promotes longevity and protects against cardiovascular and renal diseases. Klotho has been shown to activate Nrf2 and attenuate oxidative damage in neuronal cells, however, the mechanisms by which it protects against vascular smooth muscle cell VSMC dysfunction elicited by Angiotensin II (AngII) remain to be elucidated. AngII contributes to vascular ageing and atherogenesis by enhancing VSMC oxidative stress, senescence and apoptosis. This study demonstrates that soluble klotho (1 nM, 24 hrs) significantly induces expression of Nrf2 and the antioxidant enzymes haeme oxygenase (HO-1) and peroxiredoxin-1 (Prx-1) and enhances glutathione levels in human aortic smooth muscle cells (HASMC). Silencing of Nrf2 attenuated the induction of HO-1 and Prx-1 expression by soluble klotho. Furthermore, soluble klotho protected against AngII-mediated HASMC apoptosis and senescence via activation of Nrf2. Thus, our findings highlight a novel Nrf2-mediated mechanism underlying the protective actions of soluble klotho in HAMSC. Targeting klotho may thus represent a therapeutic strategy against VSMC dysfunction and cardiovascular ageing. PMID- 27696668 TI - The impact of EndoBarrier gastrointestinal liner in obese patients with normal glucose tolerance and in patients with type 2 diabetes. AB - AIMS: The duodenal-jejunal bypass sleeve ((DJBS) or EndoBarrier Gastrointestinal Liner) induces weight loss in obese subjects and may improve glucose homeostasis in patients with type 2 diabetes (T2D). To explore the underlying mechanisms, we evaluated postprandial physiology including glucose metabolism, gut hormone secretion, gallbladder emptying, appetite and food intake in patients undergoing DJBS treatment. MATERIAL AND METHODS: A total of 10 normal glucose-tolerant (NGT) obese subjects and 9 age-, body weight- and body mass index-matched metformin treated T2D patients underwent a liquid mixed meal test and a subsequent ad libitum meal test before implantation with DJBS and 1 week (1w) and 26 weeks (26w) after implantation. RESULTS: At 26w, both groups had achieved a weight loss of 6 to 7 kg. Postprandial glucagon-like peptide-1 (GLP-1) and peptide YY responses increased at 1w and 26w, but only in T2D subjects. In contrast, glucose dependent insulinotropic polypeptide responses were reduced only by DJBS in the NGT group. Postprandial glucose, insulin, C-peptide, glucagon, cholecystokinin and gastrin responses were unaffected by DJBS in both groups. Satiety and fullness sensations were stronger and food intake was reduced at 1w in NGT subjects; no changes in appetite measures or food intake were observed in the T2D group. No effect of DJBS on postprandial gallbladder emptying was observed, and gastric emptying was not delayed. CONCLUSIONS: DJBS-induced weight loss was associated with only marginal changes in postprandial physiology, which may explain the absence of effect on postprandial glucose metabolism. PMID- 27696669 TI - Mutant analysis by rescue gene excision: New tools for mosaic studies in Drosophila. AB - A host of classical and molecular genetic tools make Drosophila a tremendous model for the dissection of gene activity. In particular, the FLP-FRT technique for mitotic recombination has greatly enhanced gene loss-of-function analysis. This technique efficiently induces formation of homozygous mutant clones in tissues of heterozygous organisms. However, the dependence of the FLP-FRT method on cell division, and other constraints, also impose limits on its effectiveness. We describe here the generation and testing of tools for Mutant Analysis by Rescue Gene Excision (MARGE), an approach whereby mutant cells are formed by loss of a rescue transgene in a homozygous mutant organism. Rescue-transgene loss can be induced in any tissue or cell-type and at any time during development or in the adult using available heat-shock-induced or tissue-specific flippases, or combinations of UAS-FLP with Gal4 and Gal80ts reagents. The simultaneous loss of a constitutive fluorescence marker (GFP or RFP) identifies the mutant cells. We demonstrate the efficacy of the MARGE technique by flip-out (clonal and disc wide) of a Ubi-GFP-carrying construct in imaginal discs, and by inducing a known yki mutant phenotype in the Drosophila ovary. PMID- 27696670 TI - Temporal patterns of induction and recovery of biomarker transcriptional responses to 4-Nonylphenol and 17beta-estradiol in the estuarine arrow goby, Clevelandia ios. AB - Several estuaries along the Pacific Ocean coast of North America were identified recently as having elevated 4-nonylphenol (4-NP) in sediments and biota, raising concerns about reproductive impacts for wildlife given 4-NP's established estrogenic activity as an endocrine-disrupting compound. Here we characterize 4 NP mediated induction and recovery of estrogen-sensitive gene transcripts in the arrow goby (Clevelandia ios), an intertidal fish abundant in estuarine mud flats on the west coast of North America. Male gobies were exposed to waterborne 4-NP at 10 MUg/L or 100 MUg/L for 20 days followed by a 20 day depuration period. Additional males were treated with 17beta-estradiol (E2; 50 ng/L). 4-NP at 100 MUg/L elevated hepatic mRNAs encoding vitellogenins A (vtgA) and C (vtgC) and choriogenin L (chgL) within 72 h, and choriogenin H minor (chgHm) within 12 days. Hepatic mRNAs encoding estrogen receptor alpha (esr1) were also elevated after 12 days of 4-NP exposure, but returned to pre-exposure levels at 20 days even under continuing 4-NP treatment. 4-NP did not alter mRNA levels of estrogen receptor gamma (esr2a) in the liver, or of esr1, esr2a, and cytochrome P450 aromatase B (cyp19a1b) in the brain. The temporal pattern of initial induction for hepatic vtgA, vtgC, and chgL transcripts by 4-NP mirrored the pattern by E2, while chgHm and esr1 mRNA induction by 4-NP lagged 2-11 days behind the responses of these transcripts to E2. These findings establish 4-NP concentration- and time dependent induction patterns of choriogenin and vitellogenin transcription following exposure to environmentally relevant 4-NP concentrations, while concurrently demonstrating tissue-specific induction patterns for esr1 by estrogenic compounds.

PMID- 27696671 TI - Solid-phase microextraction of ultra-trace amounts of tramadol from human urine by using a carbon nanotube/flower-shaped zinc oxide hollow fiber. AB - A new method is successfully developed for the separation and determination of a very low amount of tramadol in urine using functionalized multiwalled carbon nanotubes/flower-shaped zinc oxide before solid-phase microextraction combined with gas chromatography. Under ultrasonic agitation, a sol of multiwalled carbon nanotubes and flower-shaped zinc oxide were forced into and trapped within the pore structure of the polypropylene and the sol solution immobilized into the hollow fiber. Flower-shaped zinc oxide was synthesized and characterized by Fourier transform infrared spectroscopy. The morphology of the fabricated solid phase microextraction surface was investigated by scanning electron microscopy and X-ray diffraction. The parameters affecting the extraction efficiencies were investigated and optimized. Under the optimized conditions, the method shows linearity in a wide range of 0.12-7680 ng/mL, and a low detection limit (S/N = 3) of 0.03 ng/mL. The precision of the method was determined and a relative standard deviation of 3.87% was obtained. This method was successfully applied for the separation and determination of tramadol in urine samples. The relative recovery percentage obtained for the spiked urine sample at 1000 ng/mL was 94.2%. PMID- 27696672 TI - Competitive interactions are mediated in a sex-specific manner by arbuscular mycorrhiza in Antennaria dioica. AB - Plants usually interact with other plants, and the outcome of such interaction ranges from facilitation to competition depending on the identity of the plants, including their sexual expression. Arbuscular mycorrhizal (AM) fungi have been shown to modify competitive interactions in plants. However, few studies have evaluated how AM fungi influence plant intraspecific and interspecific interactions in dioecious species. The competitive abilities of female and male plants of Antennaria dioica were examined in a greenhouse experiment. Females and males were grown in the following competitive settings: (i) without competition, (ii) with intrasexual competition, (iii) with intersexual competition, and (iv) with interspecific competition by Hieracium pilosella - a plant with similar characteristics to A. dioica. Half of the pots were grown with Claroideoglomus claroideum, an AM fungus isolated from the same habitat as the plant material. We evaluated plant survival, growth, flowering phenology, and production of AM fungal structures. Plant survival was unaffected by competition or AM fungi. Competition and the presence of AM fungi reduced plant biomass. However, the sexes responded differently to the interaction between fungal and competition treatments. Both intra- and interspecific competition results were sex-specific, and in general, female performance was reduced by AM colonization. Plant competition or sex did not affect the intraradical structures, extraradical hyphae, or spore production of the AM fungus. These findings suggest that plant sexual differences affect fundamental processes such as competitive ability and symbiotic relationships with AM fungi. PMID- 27696673 TI - Reproducing Optical Properties of Anterior Teeth after Ultra-Conservative Preparation. AB - OBJECTIVE: Selecting the appropriate material is essential when restoring color and appearance of esthetically compromised anterior teeth. CLINICAL CONSIDERATIONS: Most of the conventional restorative techniques require tooth reduction in order to mimic optical properties of a natural tooth. Fortunately, bonding techniques associated with improvements on dental ceramics esthetics allow for highly conservative treatment options in which maximum preservation of dental tissues can be attained. An analysis of different ceramic materials available and different types of tooth preparation is presented in a format of a decision tree for treatment planning. CONCLUSIONS: The suggested decision-making aims to facilitate clinicians' selection of the most appropriate restorative technique for reproducing color and appearance of anterior teeth after ultra conservative preparation and according to different clinical scenarios CLINICAL SIGNIFICANCE: The selection of the appropriate ceramic material for each case is of major importance, since the entire treatment plan will be determined based on the type of ceramic material that will be used for the final restoration. Each restorative material has a specific tooth preparation requirement, indications, and limitations that shall be respected for maximum esthetical outcomes. (J Esthet Restor Dent 28:267-276, 2016). PMID- 27696674 TI - Clarifying binding difference of ATP and ADP to extracellular signal-regulated kinase 2 by using molecular dynamics simulations. AB - Extracellular signal-regulated kinase 2 is a promising target for designs and development of anticancer drugs. Molecular dynamics simulations and molecular mechanics Poisson-Boltzmann method were applied to study binding difference of ADP and ATP to extracellular signal-regulated kinase 2. The results prove that the binding ability of ATP to extracellular signal-regulated kinase 2 is stronger than that of ADP. Principal component analysis performed by using molecular dynamics trajectories suggests that binding of ADP and ATP to extracellular signal-regulated kinase 2 change motion directions of two helices alpha1 and alpha2. Residue-based free energy decomposition method was adopted to calculate contributions of separate residues to associations of ADP and ATP with extracellular signal-regulated kinase 2. The results show that ADP and ATP produce strong CH-pi interactions with five residues Ile29, Val37, Ala50, Leu105, and Leu154. In addition, five hydrogen bonding interactions of ADP and ATP with residues Lys52, Gln103, Asp104, and Met106 also stabilize bindings of ADP and ATP to extracellular signal-regulated kinase 2. Overall, the CH-pi interactions of ATP with five residues Ile29, Val37, Ala50, Leu105, and Leu154 are stronger than ADP. This study is expected to contribute a significant theoretical hint for designs of anticancer drugs targeting extracellular signal-regulated kinase 2. PMID- 27696675 TI - MicroRNA let-7g possesses a therapeutic potential for peripheral artery disease. AB - Peripheral artery disease (PAD) is a manifestation of systemic atherosclerosis and conveys a significant health burden globally. Critical limb ischaemia encompasses the most severe consequence of PAD. Our previous studies indicate that microRNA let-7g prevents atherosclerosis and improves endothelial functions. This study aimed to investigate whether and how let-7g therapy may improve blood flow to ischaemic limbs. The present study shows that let-7g has multiple pro angiogenic effects on mouse ischaemic limb model and could be a potential therapeutic agent for PAD. Mice receiving intramuscular injection of let-7g had more neovascularization, better local perfusion and increased recruitment of endothelial progenitor cells after hindlimb ischaemia. The therapeutic effects of let-7g's on angiogenesis are mediated by multiple regulatory machinery. First, let-7g increased expression of vascular endothelial growth factor-A (VEGF-A) and VEGF receptor-2 (VEGFR-2) through targeting their upstream regulators HIF-3alpha and TP53. In addition, let-7g affected the splicing factor SC35 which subsequently enhanced the alternative splicing of VEGF-A from the anti-angiogenic isoform VEGF-A165b towards the pro-angiogenic isoform VEGF-A164a . The pleiotropic effects of let-7g on angiogenesis imply that let-7g may possess a therapeutic potential in ischaemic diseases. PMID- 27696677 TI - Human platelet antigens in Burmese, Karen and north-eastern Thais. AB - OBJECTIVES: A comparative study of allele frequencies at HPA-1 to -6 and HPA-15 in Burmese and Karen populations as well as at HPA-15 in north-eastern Thais (NET) is presented. BACKGROUND: Human platelet antigens (HPAs) are clinically important in several immune platelet disorders, including foetal and neonatal alloimmune thrombocytopenia (FNAIT), post-transfusion purpura (PTP) and platelet transfusion refractoriness (PTR). The knowledge of antigen frequencies in a population is essential for the evaluation of patients suffering from immune mediated platelet disorders. METHODS: A total of 285 unrelated, healthy Burmese, 242 Karen and 300 NET were recruited to this study. Genotype and allele frequencies of HPA-1 to -6 and HPA-15 were defined using polymerase chain reaction sequence-specific primers (PCR-SSP) RESULTS: No individuals homozygous for HPA-1bb, -2bb, -4bb, -5bb and -6bb were detected. HPA-1a, -2a, -4a, -5a and 6a were present in all samples of Burmese and Karen origin. HPA-1b, -2b, -4b, -5b and -6b were rare in these populations. The frequencies of HPA-3a/-3b were 60.4/39.6% in Burmese and 55.8/44.2% in Karen, respectively. Frequencies of HPA 15a/-15b were 57.2/42.8% in Burmese, 52.5/47.5% in Karen and 49.8/50.2% in NET. CONCLUSIONS: The frequencies of HPA genotypes in our study indicates that HPA-1a, -2a, -4a, -5a and -6a are unlikely involved in FNAIT, PTP and PTR in Burmese and Karen populations. However, HPA-1b, -2b, -3a, -3b, -4b, -5b, -6b, -15a and -15b may likely stimulate alloantibodies in these populations. PMID- 27696676 TI - Severity of experimental traumatic brain injury modulates changes in concentrations of cerebral free amino acids. AB - In this study, concentrations of free amino acids (FAA) and amino group containing compounds (AGCC) following graded diffuse traumatic brain injury (mild TBI, mTBI; severe TBI, sTBI) were evaluated. After 6, 12, 24, 48 and 120 hr aspartate (Asp), glutamate (Glu), asparagine (Asn), serine (Ser), glutamine (Gln), histidine (His), glycine (Gly), threonine (Thr), citrulline (Cit), arginine (Arg), alanine (Ala), taurine (Tau), gamma-aminobutyrate (GABA), tyrosine (Tyr), S-adenosylhomocysteine (SAH), l-cystathionine (l-Cystat), valine (Val), methionine (Met), tryptophane (Trp), phenylalanine (Phe), isoleucine (Ile), leucine (Leu), ornithine (Orn), lysine (Lys), plus N-acetylaspartate (NAA) were determined in whole brain extracts (n = 6 rats at each time for both TBI levels). Sham-operated animals (n = 6) were used as controls. Results demonstrated that mTBI caused modest, transient changes in NAA, Asp, GABA, Gly, Arg. Following sTBI, animals showed profound, long-lasting modifications of Glu, Gln, NAA, Asp, GABA, Ser, Gly, Ala, Arg, Citr, Tau, Met, SAH, l-Cystat, Tyr and Phe. Increase in Glu and Gln, depletion of NAA and Asp increase, suggested a link between NAA hydrolysis and excitotoxicity after sTBI. Additionally, sTBI rats showed net imbalances of the Glu-Gln/GABA cycle between neurons and astrocytes, and of the methyl-cycle (demonstrated by decrease in Met, and increase in SAH and l-Cystat), throughout the post-injury period. Besides evidencing new potential targets for novel pharmacological treatments, these results suggest that the force acting on the brain tissue at the time of the impact is the main determinant of the reactions ignited and involving amino acid metabolism. PMID- 27696678 TI - Effects of a progressive muscle relaxation intervention on dementia symptoms, activities of daily living, and immune function in group home residents with dementia in Japan. AB - AIM: To evaluate the effects of progressive muscle relaxation on the behavioral and psychological symptoms of dementia, activities of daily living, and immune function of elderly patients with dementia in group homes. METHODS: The participants were ranked by their group home unit. Odd ranks were assigned to the intervention group and even ranks to the control group. The intervention group participated in progressive muscle relaxation for 15 min each day for 90 days in the group environment; the control group members continued with their normal routine. All the participants' secretory immunoglobulin A was measured and they were assessed with the Neuropsychiatric Inventory-Nursing Home version, Nishimura Mental State Scale for the Elderly, and Nishimura Activities of Daily Living Scale. RESULTS: The intervention group comprised 18 participants from six units and the control group comprised 19 participants from five units. After the intervention, the Neuropsychiatric Inventory scores were significantly better in the intervention group, particularly for Agitation and Anxiety. The intervention group also showed significantly lower Apathy and Irritability scores and significant improvement in the Interest, Volition, and Social relationships scores on the Mental State Scale, with improvement in the activities of daily living total. However, there was no difference in the secretory immunoglobulin A level between the groups. CONCLUSION: The results suggest that progressive muscle relaxation improves the behavioral and psychological symptoms of dementia and activities of daily living in group home residents with dementia, but does not affect their immune function.

AB - BACKGROUND: Epstein-Barr virus (EBV) displays oncogenic properties, particularly in the immunocompromised host. Notably, hematopoietic stem cell transplantation (HSCT) recipients with a detectable blood EBV viral load (BEBVL) are considered at higher risk of post-transplant lymphoproliferative diseases (PTLD). Therefore, BEBVL is monitored after HSCT, and preemptive rituximab may be used in patients with high values. However, little is known about post-HSCT BEBVL dynamics, and the threshold that should lead to anti-CD20 therapy is poorly defined. METHODS: We retrospectively analyzed the post-HSCT BEBVL of 332 adult HSCT recipients in our center from 2005 to 2013, including the effect of rituximab. RESULTS: Detection of BEBVL >100, 1000, 5000, 10 000, and 50 000 copies/mL occurred in, respectively, 77.7%, 69.6%, 37.0%, 27.1%, and 7.5% of the patients after a respective median time of 9, 14, 15, 16, and 14 weeks. No BEBVL threshold was associated with an overall survival difference. Seventy-eight patients received rituximab, with a BEBVL decrease in most. Among patients with detectable BEBVL, long-term survival did not differ in rituximab treated and non-treated, except for patients with BEBVL >=50 000. Only one case of PTLD was observed. CONCLUSIONS: BEBVL is frequently detectable after HSCT, but suggests no strong association with survival. Preemptive rituximab therapy threshold remains to be defined.

AB - There is substantial evidence across different healthcare contexts that social determinants of health are strongly associated with morbidity and mortality in the United States. These factors, including socioeconomic status, behavior and environmental risks, education, social support, healthy food, and access to healthcare also vary widely by region and individual communities. One of the implications of heterogeneity in these risks is the potential impact on measured quality of healthcare providers. In particular, there is concern that providers treating disproportionally vulnerable communities may be disadvantaged by lack of risk adjustment for these factors that affect health but not indicators of quality of care. Recently, the National Quality Forum has endorsed risk adjustment for sociodemographic characteristics based on these concerns. These issues are salient to transplant programs since social determinants of health impact transplant patient outcomes and vary by region. In this viewpoint, we argue that integration of ecological (area-level) factors in risk adjustment models used to assess transplant center quality should be strongly considered. We believe this reform could be accomplished rapidly, would attenuate disparities in access to care by reducing disincentives to treat patients from vulnerable communities, and improve risk adjustment and calibration of models used for center evaluations. PMID- 27696680 TI - Autoregulation of retinal homeobox (rax) gene promoter activity through a highly conserved genomic element. AB - The Retinal homeobox (rax) gene is expressed in vertebrate retinal progenitor and stem cells and is essential for retinal development. In frogs, rax is expressed in the ciliary marginal zone (CMZ), a region containing retinal progenitor and stem cells at the anterior of the eye. Little is known regarding regulation of rax transcription and regulation of transcription of rax targets. We found that three ultra-conserved genomic elements (UCEs) flanking the rax coding region regulate expression of a rax promoter-GFP transgene in Xenopus tadpoles. One of these elements, UCE1, regulates expression of the transgene in the dorsal CMZ. UCE1 contains a Rax binding site, PCE-1. We demonstrate that rax regulates expression of the transgene through the PCE-1 site found in UCE1. Therefore, rax transcription in the CMZ is controlled, in part, by autoregulatory mechanisms. PMID- 27696683 TI - The APSES transcription factor Vst1 is a key regulator of development in microsclerotium- and resting mycelium-producing Verticillium species. AB - Plant pathogens of the genus Verticillium pose a threat to many important crops worldwide. They are soil-borne fungi which invade the plant systemically, causing wilt symptoms. We functionally characterized the APSES family transcription factor Vst1 in two Verticillium species, V. dahliae and V. nonalfalfae, which produce microsclerotia and melanized hyphae as resistant structures, respectively. We found that, in V. dahliae Deltavst1 strains, microsclerotium biogenesis stalled after an initial swelling of hyphal cells and cultures were never pigmented. In V. nonalfalfae Deltavst1, melanized hyphae were also absent. These results suggest that Vst1 controls melanin biosynthesis independent of its role in morphogenesis. The absence of vst1 also had a great impact on sporulation in both species, affecting the generation of the characteristic verticillate conidiophore structure and sporulation rates in liquid medium. In contrast with these key roles in development, Vst1 activity was dispensable for virulence. We performed a microarray analysis comparing global transcription patterns of wild type and Deltavst1 in V. dahliae. G-protein/cyclic adenosine monophosphate (G protein/cAMP) signalling and mitogen-activated protein kinase (MAPK) cascades are known to regulate fungal morphogenesis and virulence. The microarray analysis revealed a negative interaction of Vst1 with G-protein/cAMP signalling and a positive interaction with MAPK signalling. This analysis also identified Rho signalling as a potential regulator of morphogenesis in V. dahliae, positively interacting with Vst1. Furthermore, it exposed the association of secondary metabolism and development in this species, identifying Vst1 as a potential co regulator of both processes. Characterization of the putative Vst1 targets identified in this study will aid in the dissection of specific aspects of development. PMID- 27696684 TI - A literature review of reports of the stability and storage of common injectable chemotherapy agents used in veterinary patients. AB - Many chemotherapy drugs used in human patients are discarded after single use or within 24 h of reconstitution, as per the manufacturer's product label recommendations. This can be wasteful and costly to veterinary clients. This report reviews the published stability and storage data for 19 injectable chemotherapy drugs commonly used in veterinary medicine. Based on these data, storage procedures are presented, assuming aseptic technique and a closed system drug transfer device (CSDTD) are used for drug preparation and handling. Further studies on the risk of microbiological contamination of chemotherapeutics using a CSDTD, and validated high quality drug assays such as stability-indicating high performance liquid chromatography, are required. The authors' intent is not to supersede product label recommendations, but to suggest that longer storage without significant loss of drug efficacy may be possible, thus reducing the costs of chemotherapeutics to some veterinary clients. PMID- 27696685 TI - Structural basis for endotoxin neutralization by the eosinophil cationic protein. AB - Acute infection by Gram-negative pathogens can induce an exacerbated immune response that leads to lethal septic shock syndrome. Bacterial lipopolysaccharide (LPS) is a major pathogen-associated molecular pattern molecule that can initiate massive and lethal immune system stimulation. Therefore, the development of new and effective LPS-neutralizing agents is a top priority. The eosinophil cationic protein (ECP) is an antimicrobial protein secreted in response to infection, with a remarkable affinity for LPS. In the present study, we demonstrate that ECP is able to neutralize bacterial LPS and inhibit tumor necrosis factor-alpha production in human macrophages. We also characterized ECP neutralizing activity using progressively truncated LPS mutants, and conclude that the polysaccharide moiety and lipid A portions are required for LPS-mediated neutralization. In addition, we mapped the structural determinants required for the ECP-LPS interaction by nuclear magnetic resonance. Our results show that ECP is able to neutralize LPS and therefore opens a new route for developing novel therapeutic agents based on the ECP structural scaffolding. PMID- 27696686 TI - Dehomocysteinylation is catalysed by the sirtuin-2-like bacterial lysine deacetylase CobB. AB - Hyperhomocysteinemia, which is characterized by elevated blood levels of the non protein amino acid homocysteine (Hcy), is an independent risk factor for many diseases, including cardiovascular diseases, neurodegenerative diseases and birth defects. The incorporation of homocysteine into proteins, known as protein N homocysteinylation, has been considered a major mechanism that contributes to hyperhomocysteinemia. However, the process of dehomocysteinylation, the N homocysteinylation substrates and the regulatory enzyme(s) remain largely unknown. In this study, we observed that the dehomocysteinylation reaction is a spontaneous process that can be inhibited by blocking -SH groups, which have been demonstrated to be critical for non-enzymatic dehomocysteinylation reactions. We also report that CobB, a known Sir2-like bacterial lysine deacetylase, catalyzes lysine dehomocysteinylation reactions both in vitro and in vivo. Our work provides insight into how this non-enzymatic modification might be removed from affected proteins, supplies potential targets for developing identification methods for N-homocysteine proteins, and identifies CobB as the first prokaryotic dehomocysteinylation enzyme. PMID- 27696687 TI - Phosphatidic acid induces decidualization by stimulating Akt-PP2A binding in human endometrial stromal cells. AB - Decidualization of human endometrial stromal cells (hESCs) is crucial for successful uterine implantation and maintaining pregnancy. We previously reported that phospholipase D1 (PLD1) is required for cAMP-induced decidualization of hESCs. However, the mechanism by which phosphatidic acid (PA), the product of PLD1 action, might regulate decidualization is not known. We confirmed that PA induced decidualization of hESCs by observing morphological changes and measuring increased levels of decidualization markers such as IGFBP1 and prolactin transcripts (P < 0.05). Treatment with PA reduced phosphorylation of Akt and consequently that of FoxO1, which led to the increased IGFBP1 and prolactin mRNA levels (P < 0.05). Conversely, PLD1 knockdown rescued Akt phosphorylation. Binding of PP2A and Akt increased in response to cAMP or PA, suggesting that their binding is directly responsible for the inactivation of Akt during decidualization. Consistent with this observation, treatment with okadaic acid, a PP2A inhibitor, also inhibited cAMP-induced decidualization by blocking Akt dephosphorylation. PMID- 27696689 TI - Public Healthcare Entitlements and Healthcare Utilisation among the Older Population in Ireland. AB - The use of direct out-of-pocket payments to finance general practitioner (GP) care by the majority of the population in Ireland is unusual in a European context. Currently, approximately 40% of the population have means-tested access to free GP care, while the remainder must pay the full out-of-pocket cost. In this paper, we use data from The Irish Longitudinal Study on Ageing (TILDA) to examine the impact of the current system of public healthcare entitlements on GP utilisation among the older population. Using difference-in-difference propensity score matching methods, we find significant effects of changes in public healthcare entitlements on GP utilisation (i.e. introducing user fees reduces utilisation, while removing them increases utilisation). There is limited evidence of offset effects on other types of healthcare utilisation. The results have direct implications for current Irish health policy, and add to the international literature on the effects of insurance on healthcare utilisation.

AB - Children with autism may have difficulties with visual disengagement-that is, inhibiting current fixations and orienting to new stimuli in the periphery. These difficulties may limit these children's ability to flexibly monitor the environment, regulate their internal states, and interact with others. In typical development, visual disengagement is influenced by a phasic alerting network that increases the processing speed of the visual system after salient events. The role of the phasic alerting effect in the putative atypical disengagement performance in autism spectrum disorder (ASD) is not known. Here, we compared visual disengagement in six-year-old children with autism (N = 18) and typically developing children (N = 17) matched for age and nonverbal IQ. We manipulated phasic alerting during a visual disengagement task by adding spatially nonpredictive sounds shortly before the onset of the visual peripheral targets. Children with ASD showed evidence of delayed disengagement compared to the control group. Sounds facilitated visual disengagement similarly in both groups, suggesting typical modulation by phasic alerting in ASD in the context of this task. These results support the view that atypical visual disengagement in ASD is related to other factors than atypicalities in the alerting network. Autism Res 2017, 10: 539-545.

PMID- 27696690 TI - New York University School of Medicine Drug Development Educational Program: 2 Year Benchmark. AB - Drug development (DD) is a multidisciplinary process that spans the translational continuum, yet remains an understudied entity in medical schools and biomedical science institutes. In response to a growing interest and unmet need, we implemented a DD course series that details identification of viable molecular targets, clinical trial design, intellectual property, and marketing. Enrollment is open to faculty, postdoctoral trainees, and MD, PhD, and MS students. After 2 years, 37 students and 23 students completed the fall and spring courses, respectively. Pre/post-surveys demonstrated gained knowledge across course topics, with mean survey scores increased by 66% (p < 0.001) after each course. Lectures for each course were consistently rated highly, with a mean course rating of 4.1/5. Through this program, trainees will have a more innovative approach toward identification of therapeutic targets and modalities. Furthermore, they will learn to integrate technology and biomedical informatics to find creative solutions in the DD process.

AB - Protein kinase C (PKC) signalling is critically involved in the control of blood pressure. Angiotensin-converting enzyme inhibitors (ACEi) affect PKC expression and activity, which are partially associated with the responses to ACEi. We examined whether PRKCA (protein kinase C, alpha) polymorphisms (rs887797 C>T, rs1010544 T>C and rs16960228 G>A), or haplotypes, and gene-gene interactions within the ACEi pathway affect the antihypertensive responses in 104 hypertensive patients treated with enalapril as monotherapy. Patients were classified as poor responders (PR) or good responders (GR) to enalapril if their changes in mean arterial pressure were lower or higher than the median value, respectively. Multi factor dimensionality reduction was used to characterize interactions among PRKCA, NOS3 (nitric oxide synthase 3) and BDKRB2 (bradykinin receptor B2) polymorphisms. The TC+CC genotypes for the rs1010544 polymorphism were more frequent in GR than in PR (p = 0.037). Conversely, the GA+AA genotypes for the rs16960228 polymorphism, and the CTA haplotype, were more frequent in PR than in GR (p = 0.040 and p = 0.008, respectively). Moreover, the GG genotype for the PRKCA rs16960228 polymorphism was associated with PR or GR depending on the genotypes for the rs2070744 (NOS3) and rs1799722 (BDKRB2) polymorphisms (p = 0.012). Our results suggest that PRKCA polymorphisms and gene-gene interactions within the ACEi pathway affect the antihypertensive responses to enalapril. PMID- 27696693 TI - The silent overall burden of foot disease in a representative hospitalised population. AB - The aims of this study were to investigate the point prevalence, and associated independent factors, for foot disease (ulcers, infections and ischaemia) in a representative hospitalised population. We included 733 (83%) of 883 eligible adult inpatients across five representative Australian hospitals on one day. We collected an extensive range of self-reported characteristics from participants. We examined all participants to clinically diagnose foot disease (ulcers, infections and ischaemia) and amputation procedures. Overall, 72 participants (9.8%) [95% confidence interval (CI):7.2-11.3%] had foot disease. Foot ulcers, in 49 participants (6.7%), were independently associated with peripheral neuropathy, peripheral arterial disease, previous foot ulcers, trauma and past surgeon treatment (P < 0.05). Foot infections, in 24 (3.3%), were independently associated with previous foot ulcers, trauma and past surgeon treatment (P < 0.01). Ischaemia, in 33 (4.5%), was independently associated with older age, smokers and past surgeon treatment (P < 0.01). Amputation procedures, in 14 (1.9%), were independently associated with foot infections (P < 0.01). We found that one in every ten inpatients had foot disease, and less than half of those had diabetes. After adjusting for diabetes, factors linked with foot disease were similar to those identified in diabetes-related literature. The overall inpatient foot disease burden is similar in size to well-known medical conditions and should receive similar attention. PMID- 27696694 TI - The care of transmetatarsal amputation in diabetic foot gangrene. AB - Diabetic foot ulcerations may determine minor or major amputation, with a high impact on patients' life expectation and quality of life and on economic burden. Among minor amputations, transmetatarsal amputation (TMA) appears to be the most effective in terms of limb salvage rates and in maintaining foot and ankle biomechanics. In spite of this, TMA needs particular pre- and postoperative management in order to avoid the frequent failure rates. A systematic review was undertaken of studies concerning TMA and its care in diabetic foot gangrene. Studies were identified by searching the MEDLINE, Scopus and Science Direct databases until 13 January 2016. All studies were assessed using the Downs and Black quality checklist. Of the 348 records found, 86 matched our inclusion criteria. After reading the full-text articles, we decided to exclude 35 manuscripts because of the following reasons: (1) no innovative or important content, (2) no multivariable analysis, (3) insufficient data, (4) no clear potential biases or strategies to solve them, (5) no clear endpoints and (6) inconsistent or arbitrary conclusions. The final set included 51 articles. In the current literature, there are less data about TMA, indication for the selection of patients, outcomes and complications. Generally, the judgment of an experienced physician is one of the best indicators of subsequent healing. Ankle brachial indices, toe pressures, laser Doppler skin perfusion pressures, angiography and Doppler assessment of foot vasculature may help physicians in this decision. In any case, despite the presumed lower healing rate, it is reasonable to pursue a TMA in a patient with a higher likelihood of continued ambulation. Furthermore, tailored wound closure, adjuvant local treatments and the choice of the most appropriate antibiotic therapy, when infection occurs, are pivotal elements for the success of TMA procedures. TMA is a valuable option for diabetic foot gangrene that can prevent major limb loss and minimise loss of function, thus improving the quality of life for diabetic patients. PMID- 27696695 TI - Blunt chest trauma in a non-specialist centre: Right treatment, right place? AB - OBJECTIVES: To compare patient characteristics, management and outcomes for patients admitted with isolated blunt chest trauma, managed by medical or surgical teams. METHODS: We reviewed adult patients admitted with blunt chest trauma between 1 September 2006 and 31 August 2011 to a secondary hospital in New Zealand. Inclusion criteria were: blunt chest trauma, with at least one radiologically demonstrated rib fracture. The primary outcome was in-hospital mortality, and secondary outcomes were development of pneumonia, and use of analgesia. RESULTS: Seventy-two patients were included. Thirty-three patients were managed by medical teams and 39 by surgical teams. In-hospital mortality was greater amongst medical patients 5/33 (15%) versus surgical 0/39 (0%); P = 0.012. Pneumonia occurred in 15/33 (45%); medical patients versus surgical 2/39 (5%), P <0.001. Use of epidural, regional or patient-controlled analgesia was greater in the group managed by surgical teams (12/39 [30.7%] vs 1/33 [3%] P = 0.002). Medically managed patients were older (median 73 vs 63 years; P = 0.02), had a higher Charlson Comorbidity Index (median 5 vs 3; P = 0.013). The mechanism of injury for medically managed patients was more likely to be low trauma fall compared to surgically managed patients (28/33 [85%] vs 9/39 [27%]; P <0.0001). CONCLUSION: Amongst patients with isolated blunt chest trauma, those managed by medical teams were older, had more comorbidities and were more likely to have become injured with a low trauma fall than those managed by surgical teams. They had less access to analgesic options, developed pneumonia more often and had higher mortality. PMID- 27696697 TI - Prescribing antibiotics in diabetic foot infection: what is the role of initial microscopy and culture of tissue samples? AB - The aim of this study was to evaluate the role of microscopy, Gram stain and the culture of tissue samples in the antibiotic treatment of patients with diabetic foot infection. A retrospective review of patients with a diabetic foot infection was undertaken. Data analysed included the severity of infection, antibiotic prescribing patterns, microscopy and culture results. A total of 71 patients were included, from whom 114 tissue samples were collected. Gram stain results were in agreement with final culture results in 45.8% (n = 54) of samples. Overall sensitivity and specificity of the Gram stains were low (74.5% and 69.8%, respectively), although the specificity for Gram-negative rods was high (98.5%). The presence or absence of 'pus cells' on microscopy was a poor predictor of culture results. Empirical prescribing of antibiotics was in accordance with local policy in 31.1% of patients, improving to 86.8 % following culture results. Microscopy, a skilled laboratory procedure, was generally a poor predictor of tissue culture results. However, the presence of Gram-negative rods was suggestive of isolation in the culture of such organisms and could allow the early broadening of antibiotic treatment. Despite initial poor compliance of empirical antibiotic treatment regimens, prescribing was adjusted in light of culture results, suggesting these were important for clinicians. PMID- 27696696 TI - Growth of Pseudomonas taiwanensis VLB120?C biofilms in the presence of n-butanol. AB - Biocatalytic processes often encounter problems due to toxic reactants and products, which reduce biocatalyst viability. Thus, robust organisms capable of tolerating or adapting towards such compounds are of high importance. This study systematically investigated the physiological response of Pseudomonas taiwanensis VLB120?C biofilms when exposed to n-butanol, one of the potential next generation biofuels as well as a toxic substance using microscopic and biochemical methods. Initially P. taiwanensis VLB120?C biofilms did not show any observable growth in the presence of 3% butanol. Prolonged cultivation of 10 days led to biofilm adaptation, glucose and oxygen uptake doubled and consequently it was possible to quantify biomass. Complementing the medium with yeast extract and presumably reducing the metabolic burden caused by butanol exposure further increased the biomass yield. In course of cultivation cells reduced their size in the presence of n-butanol which results in an enlarged surface-to-volume ratio and thus increased nutrient uptake. Finally, biofilm enhanced its extracellular polymeric substances (EPS) production when exposed to n-butanol. The predominant response of these biofilms under n-butanol stress are higher energy demand, increased biomass yield upon medium complements, larger surface-to-volume ratio and enhanced EPS production. Although we observed a distinct increase in biomass in the presence of 3% butanol it was not possible to cultivate P. taiwanensis VLB120?C biofilms at higher n-butanol concentrations. Thereby this study shows that biofilms are not per se tolerant against solvents, and need to adapt to toxic n-butanol concentrations. PMID- 27696698 TI - The relationship between cognitive and neuroimaging outcomes in children treated for acute lymphoblastic leukemia with chemotherapy only: A systematic review. AB - Cognitive late-effects have been identified in patients treated with chemotherapy only protocols for childhood acute lymphoblastic leukemia (ALL), yet the underlying neuropathology is not well understood. This review synthesized recent findings from eight articles investigating the relationship between neurocognitive and neuroimaging outcomes for patients treated for ALL with chemotherapy-only protocols. Reported cognitive domains, imaging methods, and neuroanatomy examined were variable. Despite this, 62.5% (n = 5) of the reviewed studies found a significant relationship between cognitive and imaging outcomes. Greater understanding of the effects of treatment on neuroanatomy and cognitive outcomes is critical for proactively managing ALL cognitive late-effects. Research directions are suggested. PMID- 27696699 TI - Enhancement of wound closure by modifying dual release patterns of stromal derived cell factor-1 and a macrophage recruitment agent from gelatin hydrogels. AB - The objective of the present study is to evaluate the effects of the release patterns of stromal derived factor (SDF)-1 and sphingosine-1 phosphate agonist (SEW2871), used as MSC and macrophage recruitment agents, on the wound closure of diabetic mouse skin defects. To achieve different release patterns, hydrogels were prepared using two types of gelatin with isoelectric points (IEP) of 5 and 9, into which SDF-1 and SEW2871 were then incorporated in various combinations. When the hydrogels incorporating SDF-1 and SEW2871 were applied into wound defects of diabetic mice, the number of MSCs and macrophages recruited to the defects and the levels of pro- and anti- inflammatory cytokines were found to be dependent on the release profiles of SDF-1 and SEW2871. Of particular interest was the case of a rapid release of SDF-1 combined with a controlled release of SEW2871. This resulted in a higher number of M2 macrophages and gene expression levels of anti-inflammatory cytokines 3 days after implantation and faster wound closure than when pairing the controlled release of SDF-1 with a rapid release of SEW2871. Therefore, the present study demonstrates that different release patterns of SDF-1 and SEW2871 can enhance the in vivo recruitment of MSCs and macrophages, and can promote skin wound closure through the modulation of inflammation.

AB - OBJECTIVE: Localized scleroderma can negatively affect children's quality of life (QoL), but predictors of impact have not been well described. We sought to identify predictors of QoL impact in juvenile localized scleroderma patients. METHODS: We analyzed longitudinal data from a single-center cohort of juvenile localized scleroderma patients, using hierarchical generalized linear modeling (HGLM) to identify predictors of QoL impact. HGLM is useful for nested data and allows for evaluation of both time-variant and time-invariant predictors. RESULTS: The number of extracutaneous manifestations (ECMs; e.g., joint contracture and hemifacial atrophy) and female sex predicted negative QoL impact, defined as a Children's Dermatology Life Quality Index score >1 (P = 0.019 for ECMs and P = 0.002 for female sex). As the time since the initial visit increased, the odds of reporting a negative QoL impact decreased (P < 0.001). CONCLUSION: Our results suggest that ECMs, sex, and time since initial visit are more predictive of QoL impact in localized scleroderma than cutaneous features. Further study is required to determine which ECMs have the most impact on QoL, which factors underlie sex differences in QoL in localized scleroderma, and why increasing the time since the initial visit appears to be protective. An improved understanding of predictors of QoL impact may allow for the identification of patients at risk of poorer outcomes and for the tailoring of treatment and psychosocial support. PMID- 27696701 TI - The long-term recurrence risk of patients with unprovoked venous thromboembolism: an observational cohort study. AB - : Essentials Long-term recurrence risk of venous thromboembolism (VTE) is uncertain. We performed a prospective cohort study of 839 patients with first unprovoked VTE. VTE recurrence risk is high, particularly in men with proximal thrombosis or pulmonary embolism. Sex and VTE site determine the recurrence risk and should be considered for patient counseling. SUMMARY: Background The long term recurrence risk (ltRR) of venous thromboembolism (VTE) is uncertain. Objective To assess the ltRR of patients with first unprovoked VTE. Patients/methods Patients were classified into three categories: distal deep vein thrombosis (DVT), proximal DVT or pulmonary embolism (PE), that is, PE associated with DVT or isolated PE. Patients with major thrombophilia or antithrombotic therapy were excluded. The endpoint was recurrent symptomatic VTE. Results A total of 839 patients were followed for a median of 7.7 years. VTE recurred in 263 patients (31%). After 10 and 20 years, the cumulative ltRR was 32% (95% confidence interval [CI], 29-36) and 44% (95% CI, 38-49) with 3.9 (95% CI, 3.3 4.6) and 3.3 (95% CI, 2.7-4.0) events per 100 patient-years, respectively. The adjusted hazard ratio was 2.1 (95% CI, 1.4-3.2) and 2.1 (95% CI, 1.4-3.2) for patients with proximal DVT or PE compared with patients with distal DVT and was 2.1 (95% CI, 1.6-2.9) for men compared with women. At 10 years, 4.7 (95% CI, 3.8 5.8) events per 100 patient-years occurred in men with proximal DVT or PE, 2.4 (95% CI, 1.2-4.4) in men with distal DVT, 1.9 (95% CI, 1.2-2.8) in women with proximal DVT or PE and 0.9 (95% CI, 0.2-1.9) in women with distal DVT. Conclusion The ltRR of patients with first unprovoked VTE is high and dependent upon sex and VTE site. PMID- 27696704 TI - Erratum. PMID- 27696702 TI - Distinct roles of immunoreceptor tyrosine-based motifs in immunosuppressive indoleamine 2,3-dioxygenase 1. AB - The enzyme indoleamine 2,3-dioxygenase 1 (IDO1) catalyses the initial, rate limiting step in tryptophan (Trp) degradation, resulting in tryptophan starvation and the production of immunoregulatory kynurenines. IDO1's catalytic function has long been considered as the one mechanism responsible for IDO1-dependent immune suppression by dendritic cells (DCs), which are master regulators of the balance between immunity and tolerance. However, IDO1 also harbours immunoreceptor tyrosine-based inhibitory motifs, (ITIM1 and ITIM2), that, once phosphorylated, bind protein tyrosine phosphatases, (SHP-1 and SHP-2), and thus trigger an immunoregulatory signalling in DCs. This mechanism leads to sustained IDO1 expression, in a feedforward loop, which is particularly important in restraining autoimmunity and chronic inflammation. Yet, under specific conditions requiring that early and protective inflammation be unrelieved, tyrosine-phosphorylated ITIMs will instead bind the suppressor of cytokine signalling 3 (SOCS3), which drives IDO1 proteasomal degradation and shortens the enzyme half-life. To dissect any differential roles of the two IDO1's ITIMs, we generated protein mutants by replacing one or both ITIM-associated tyrosines with phospho-mimicking glutamic acid residues. Although all mutants lost their enzymic activity, the ITIM1 - but not ITIM2 mutant - did bind SHPs and conferred immunosuppressive effects on DCs, making cells capable of restraining an antigen-specific response in vivo. Conversely, the ITIM2 mutant would preferentially bind SOCS3, and IDO1's degradation was accelerated. Thus, it is the selective phosphorylation of either ITIM that controls the duration of IDO1 expression and function, in that it dictates whether enhanced tolerogenic signalling or shutdown of IDO1-dependent events will occur in a local microenvironment. PMID- 27696703 TI - Personalized Physical Therapy Versus Usual Care for Patients With Systemic Sclerosis: A Randomized Controlled Trial. AB - OBJECTIVE: To compare a physical therapy program to usual care of systemic sclerosis (SSc) patients on disability. METHODS: A 12-month followup, parallel group randomized controlled trial involving a modified Zelen design was conducted in 4 tertiary-care hospitals. Patients were enrolled if they had a disability rating >=0.5 on the Health Assessment Questionnaire disability index (HAQ DI) or symptoms of decreased mouth opening or limited range of motion of at least 1 joint. The experimental intervention (n = 112, of which 110 were analyzed) was a 1-month personalized supervised physical therapy program provided by trained care providers followed by home sessions. The comparator (n = 108, and all 108 were analyzed) was usual care that could include ambulatory physical therapy. The primary outcome was the HAQ DI score. RESULTS: There was no statistically significant difference in disability at 12 months (HAQ DI score between-group difference -0.01 [95% confidence interval (95% CI) -0.15, 0.13]; P = 0.86). Disability was reduced at 1 month for patients in the physical therapy group (HAQ DI between-group difference -0.14 [95% CI -0.24, -0.03]; P = 0.01); at 6 months the HAQ DI score between-group difference was -0.12 (95% CI -0.23, 0.01); P = 0.054. There was a statistically significant difference for hand mobility and function, and for pain, at 1 month. Microstomia was lower in the physical therapy group at 1, 6, and 12 months (between-group difference at 12 months 1.62 [95% CI 0.32, 2.93]; P = 0.01). No differences in adverse effects were observed. CONCLUSION: A personalized physical therapy program did not reduce disability at 12 months but had short-term benefits for patients with SSc. PMID- 27696705 TI - What is the chance all your trainees will pass the next Fellowship exam: A statistician's view. AB - Your department has had a good track record over many years for preparing trainees to successfully sit for the ACEM Fellowship exam. On average the pass rate for your trainees is over 80%. Then, to your dismay, suddenly only two of five of your trainees pass the latest Fellowship exam. Does this anomaly necessitate an urgent review of your department's training programme, or is it just a statistical quirk? Let us suppose you can prepare candidates so that they all have at least an 80% chance of passing. The probability that all five candidates would have passed is 32.8% (or 0.85 ) based on the multiplication rule of probability for independent events. The probability that only two of five passed is 5.1% (or 10 * 0.82 * 0.23 ) based on the binomial distribution, which is a probability distribution analogous to the normal distribution. The construction of the binomial distribution depends on two parameters: (i) number of candidates sitting ('n'), and (ii) probability of passing for any individual candidate ('P'). The distribution gives the probability that 'x' number of individuals will pass when 'n' number of individuals sit. Thus despite an 80% pass rate historically, the probability that only two of five candidates will pass is not negligible at 5.1%. It is an anomaly, which we may choose not to act on unless it is recurrent, noting it will be expected to occur naturally about one time out of 20. The real challenge is to maintain or increase that individual probability at 80% or higher.

PMID- 27696706 TI - The cephalic labial gland secretions of two socially parasitic bumblebees Bombus hyperboreus (Alpinobombus) and Bombus inexspectatus (Thoracobombus) question their inquiline strategy. AB - Social parasitic Hymenopterans have evolved morphological, chemical, and behavioral adaptations to overcome the sophisticated recognition and defense systems of their social host to invade host nests and exploit their worker force. In bumblebees, social parasitism appeared in at least 3 subgenera independently: in the subgenus Psithyrus consisting entirely of parasitic species, in the subgenus Alpinobombus with Bombus hyperboreus, and in the subgenus Thoracobombus with B. inexspectatus. Cuckoo bumblebee males utilize species-specific cephalic labial gland secretions for mating purposes that can impact their inquiline strategy. We performed cephalic labial gland secretions in B. hyperboreus, B. inexspectatus and their hosts. Males of both parasitic species exhibited high species specific levels of cephalic gland secretions, including different main compounds. Our results showed no chemical mimicry in the cephalic gland secretions between inquilines and their host and we did not identify the repellent compounds already known in other cuckoo bumblebees. PMID- 27696708 TI - Pedicled medial sural perforator flap for the reconstruction of knee defects. AB - Soft tissue defects exposing the patellar tendon or bone are common in patients who have experienced trauma or implant infection. The purpose of this article is to present our experience of six patients who underwent reconstruction of soft tissue defects of the knee using a pedicled medial sural perforator flap. Between November 2013 and November 2015, six patients who presented with a soft tissue defect overlying the knee were admitted to our hospital. After adequate debridement or wide excision of the tumour, these patients underwent pedicled medial sural perforator flap placement to resurface the complex soft tissue defects and to provide a gliding surface for the exposed patellar tendon. The patients' age, comorbidity, aetiology, defect size and location, flap size, perforator numbers and lengths, outcome and follow-up period were reviewed. The six medial sural perforator flaps survived completely, and the wounds healed satisfactorily over a mean follow-up of 21.5 months (range, 6-51 months). Donor sites were closed primarily or covered with a split-thickness skin graft. The medial sural perforator flap is a reliable flap for coverage of defects overlying the knee. The thin and pliable flap, long pedicle length and less donor site mobility benefit patients. Thus, the medial sural perforator flap may be a valuable alternative for defect reconstructions overlying the knee, which produces satisfactory results both functionally and cosmetically. PMID- 27696709 TI - Axially vascularized tissue-engineered bone constructs retain their in vivo angiogenic and osteogenic capacity after high-dose irradiation. AB - In order to introduce bone tissue engineering to the field of oncological reconstruction, we are investigating for the first time the effect of various doses of ionizing irradiation on axially vascularized bone constructs. Synthetic bone constructs were created and implanted in 32 Lewis rats. Each construct was axially vascularized through an arteriovenous loop made by direct anastomosis of the saphenous vessels. After 2 weeks, the animals received ionizing irradiation of 9 Gy, 12 Gy and 15 Gy, and were accordingly classified to groups I, II and III, respectively. Group IV was not irradiated and acted as a control. Tissue generation, vascularity, cellular proliferation and apoptosis were investigated either 2 or 5 weeks after irradiation through micro-computed tomography, histomorphometry and real-time polymerase chain reaction (PCR). At 2 weeks after irradiation, tissue generation and central vascularity were significantly lower and apoptosis was significantly higher in groups II and III than group IV, but without signs of necrosis. Cellular proliferation was significantly lower in groups I and II. After 5 weeks, the irradiated groups showed improvement in all parameters in relation to the control group, indicating a retained capacity for angiogenesis after irradiation. PCR results confirmed the expression of osteogenesis-related genes in all irradiated groups. Dense collagen was detected 5 weeks after irradiation, and one construct showed discrete islands of bone indicating a retained osteogenic capacity after irradiation. This demonstrates for the first time that axial vascularization was capable of supporting a synthetic bone construct after a high dose of irradiation that is comparable to adjuvant radiotherapy.

AB - Manufacture of red blood cells (RBCs) from progenitors has been proposed as a method to reduce reliance on donors. Such a process would need to be extremely efficient for economic viability given a relatively low value product and high (2 * 1012 ) cell dose. Therefore, the aim of these studies was to define the productivity of an industry standard stirred-tank bioreactor and determine engineering limitations of commercial red blood cells production. Cord blood derived CD34+ cells were cultured under erythroid differentiation conditions in a stirred micro-bioreactor (AmbrTM). Enucleated cells of 80% purity could be created under optimal physical conditions: pH 7.5, 50% oxygen, without gas sparging (which damaged cells) and with mechanical agitation (which directly increased enucleation). O2 consumption was low (~5 * 10-8 MUg/cell.h) theoretically enabling erythroblast densities in excess of 5 * 108 /ml in commercial bioreactors and sub-10 l/unit production volumes. The bioreactor process achieved a 24% and 42% reduction in media volume and culture time, respectively, relative to unoptimized flask processing. However, media exchange limited productivity to 1 unit of erythroblasts per 500 l of media. Systematic replacement of media constituents, as well as screening for inhibitory levels of ammonia, lactate and key cytokines did not identify a reason for this limitation. We conclude that the properties of erythroblasts are such that the conventional constraints on cell manufacturing efficiency, such as mass transfer and metabolic demand, should not prevent high intensity production; furthermore, this could be achieved in industry standard equipment. However, identification and removal of an inhibitory mediator is required to enable these economies to be realized.

PMID- 27696711 TI - Ewing sarcoma family of tumors in children younger than 10 years of age. AB - AIM: Few data exist regarding the clinical characteristics and outcome of young children with Ewing sarcoma family of tumors (ESFT). METHODS: We reviewed the records of ESFT patients at our institution younger than 10 years of age at diagnosis. RESULTS: Forty-two patients were identified. Median age was 6.4 years (range 0.6-9.5 years). Most patients had T2 (>5 cm) tumors (n = 31; 74%). Most common primary site was the extremity (n = 17; 41%). Seven patients (17%) had metastasis at diagnosis. For local tumor control, 20 patients had surgery only, 13 had radiation therapy only, and 6 had surgery plus radiation. Surgical margin status was negative in 19 patients (73%). Median follow-up was 4.7 years (range 0.7-29.7 years), and 5-year relapse-free survival (RFS) and overall survival (OS) estimates were 67% (95% CI: 53-84%) and 82% (95% CI: 71-95%), respectively. Metastasis at presentation was the only significant predictor for decreased RFS (P = 0.008) and OS (P = 0.01). A trend was seen for T2 tumors with worse OS (P = 0.09). CONCLUSION: Patients younger than 10 years of age with ESFT may have a better OS than older patients, but further study of a homogeneously treated larger cohort is needed.

PMID- 27696713 TI - Mesenchymal stromal cells regulate the cell mobility and the immune response during osteogenesis through secretion of vascular endothelial growth factor A. AB - Cell-cell interaction is believed to play a critical role in the cell-based therapy for bone regeneration. However, the mechanisms involved in the interaction between donor cells and host cells during the bone healing process are still not clear. This study investigated the potential effect of vascular endothelial growth factor A (VEGFA) produced by osteogenically differentiated mesenchymal stem cells (O-MSCs) on the recruitment and regulation of undifferentiated MSCs and macrophages during osteogenesis. Factors secreted from MSCs during osteogenic differentiation were monitored by cytokine arrays. Indirect coculture models were applied to study the effect of VEGFA derived from O-MSCs on the motility, cell morphology and CXCL12/CXCR4 expression in MSCs as well as the regulation of local immune response. A mouse skull defect model was used to unveil the cell recruitment, macrophage activity and new bone formation following O-MSCs transplantation. It was found that VEGFA secretion increased dramatically during the osteogenic differentiation of MSCs. The secreted VEGFA by O-MSCs stimulated the expression of CXCL12/CXCR4, resulting in the recruitment of MSCs and macrophages to the bone defects. It was noted that O-MSCs could regulate the local inflammation by modulating the expression of proinflammatory cytokines in macrophages and neutralizing VEGFA produced by O-MSCs resulted in significant decrease of cell recruitment, cytokine secretion and new bone formation. This study demonstrates that VEGFA secreted by O-MSCs plays a pivotal role in the cell recruitment and regulation of local immune response during osteogenesis.

PMID- 27696714 TI - Investigation of multivalent interactions between conjugate of quantum dots with c-Myc peptide tag and the anti-c-Myc antibody by capillary electrophoresis with fluorescence detection. AB - Herein, we report an assay for detecting the binding of a multivalent peptide and antibody within a capillary with the use of fluorescence coupled capillary electrophoresis. Quantum dots and a c-Myc tag containing peptide EQKLISEEDLG4 H6 were injected sequentially and formed a multivalent quantum dot-EQKLISEEDLG4 H6 assembly within the capillary. The efficiency of the quantum dot-peptide self assembly was affected by the peptide/quantum dot molar ratio, sampling time, and interval time. Finally, the binding of the monoclonal anti-c-Myc antibody and the multivalent quantum dot-EQKLISEEDLG4 H6 ligand was studied using an in-capillary assay. The microscopic dissociation constant for the self-assembly of monoclonal anti-c-Myc antibody and quantum dot-EQKLISEEDLG4 H6 was determined to be 14.1 MUM with a stoichiometry of the peptide-antibody complex of 1.7 determined after fitting this to the Hill equation. This method can be further extended to detect a wide range of biomolecule-biomolecule binding interactions.

AB - Phenanthroline derivatives have been reported as potential bioactive compounds because of their ability to interact with DNA. To evaluate the antiproliferative effect of bis(acetylacetonate-k2 O,O)(1,10-phenanthroline-k2 N,N)Zn(II) or Zn(acac)2 (phen) complex, the compound was obtained in a simple manner and further characterized to determine crystal structure, thermal behavior, morphology, and spectroscopic properties. The structure of the complex was confirmed by X-ray single structure as well as by 1H and 13C nuclear magnetic resonance (NMR) in dmso-d6 (dimethyl sulfoxide) solution and in the solid state by 13C CP/MAS. Although preparation of this compound has been described previously, there are no reports on its biological activity; here, we assessed its antiproliferative effect on fibroblasts, A253, FaDu, Cal-27, RH-30, RD, U 373, C6, A-549, MDA-MB-231, and MCF-7 cancer cell lines at different doses (50 100 and 150 MUg/ml). The cell viability was determined by MTT assay and high activity was observed for the most of the cell lines, and TUNEL results showed the induction of apoptosis. PMID- 27696717 TI - Non-Newtonian versus numerical rheology: Practical impact of shear-thinning on the prediction of stable and unstable flows in intracranial aneurysms. AB - Computational fluid dynamics (CFD) shows promise for informing treatment planning and rupture risk assessment for intracranial aneurysms. Much attention has been paid to the impact on predicted hemodynamics of various modelling assumptions and uncertainties, including the need for modelling the non-Newtonian, shear-thinning rheology of blood, with equivocal results. Our study clarifies this issue by contextualizing the impact of rheology model against the recently demonstrated impact of CFD solution strategy on the prediction of aneurysm flow instabilities. Three aneurysm cases were considered, spanning a range of stable to unstable flows. Simulations were performed using a high-resolution/accuracy solution strategy with Newtonian and modified-Cross rheology models and compared against results from a so-called normal-resolution strategy. Time-averaged and instantaneous wall shear stress (WSS) distributions, as well as frequency content of flow instabilities and dome-averaged WSS metrics, were minimally affected by the rheology model, whereas numerical solution strategy had a demonstrably more marked impact when the rheology model was fixed. We show that point-wise normalization of non-Newtonian by Newtonian WSS values tended to artificially amplify small differences in WSS of questionable physiological relevance in already-low WSS regions, which might help to explain the disparity of opinions in the aneurysm CFD literature regarding the impact of non-Newtonian rheology. Toward the goal of more patient-specific aneurysm CFD, we conclude that attention seems better spent on solution strategy and other likely "first-order" effects (eg, lumen segmentation and choice of flow rates), as opposed to "second-order" effects such as rheology. PMID- 27696718 TI - Adolescent deliberate self-poisoning in South-East Melbourne. AB - OBJECTIVE: To describe the characteristics of adolescents presenting with deliberate self-poisoning (DSP) to a large Australian healthcare network. METHOD: This is a retrospective chart review of 12-17 year olds presenting to three Monash Health EDs with self-poisoning from January 2012 to December 2014. RESULTS: There were 35 207 adolescent presentations in the study period. A total of 721 cases were for DSP (2%), and 501 (1.4%) presented with recreational or accidental self-poisoning. The most common DSP toxicants were paracetamol (28%), non-steroidal anti-inflammatory agents (15%) and serotonin reuptake inhibitors (10%). Of the DSP presentations, 96% were impulsive events; 23% of patients (n = 129) presented on multiple occasions, and 67% of all DSP cases had a past psychiatric history, particularly depression (57%). Disposition for DSP patients included 60% discharged home, 6% short stay unit, 19% medical admission, 13% psychiatric admission and 2% intensive care unit admission. There were no mortalities. CONCLUSION: Adolescent DSP presentations frequently involved impulsive ingestion of over-the-counter medications, suggesting less access to prescription medications. Additionally, pre-existing mental health history and re presentation were common. Initiatives to prevent DSP might include an increased focus on the early identification and management of mental health problems in adolescents in the community. PMID- 27696719 TI - BK polyomavirus encephalitis in a patient with thrombotic microangiopathy after an allogeneic hematopoietic stem cell transplant. AB - To date, only one case of BK polyomavirus (BKPyV) encephalitis combined with transplant-associated thrombotic microangiopathy has been reported in an hematopoietic stem cell transplantation (HCT) recipient. We report the case of an HCT recipient who developed thrombotic microangiopathy and subsequent BKPyV encephalitis. She died despite treatment with cidofovir, ciprofloxacin, and intravenous immunoglobulin without improvement in mental status. Early suspicion of BKPyV encephalitis in an HCT recipient presenting with altered mental status and hemorrhagic cystitis is important. PMID- 27696721 TI - Metabolic profiling of recombinant Escherichia coli cultivations based on high throughput FT-MIR spectroscopic analysis. AB - Escherichia coli is one of the most used host microorganism for the production of recombinant products, such as heterologous proteins and plasmids. However, genetic, physiological and environmental factors influence the plasmid replication and cloned gene expression in a highly complex way. To control and optimize the recombinant expression system performance, it is very important to understand this complexity. Therefore, the development of rapid, highly sensitive and economic analytical methodologies, which enable the simultaneous characterization of the heterologous product synthesis and physiologic cell behavior under a variety of culture conditions, is highly desirable. For that, the metabolic profile of recombinant E. coli cultures producing the pVAX-lacZ plasmid model was analyzed by rapid, economic and high-throughput Fourier Transform Mid-Infrared (FT-MIR) spectroscopy. The main goal of the present work is to show as the simultaneous multivariate data analysis by principal component analysis (PCA) and direct spectral analysis could represent a very interesting tool to monitor E. coli culture processes and acquire relevant information according to current quality regulatory guidelines. While PCA allowed capturing the energetic metabolic state of the cell, e.g. by identifying different C sources consumption phases, direct FT-MIR spectral analysis allowed obtaining valuable biochemical and metabolic information along the cell culture, e.g. lipids, RNA, protein synthesis and turnover metabolism. The information achieved by spectral multivariate data and direct spectral analyses complement each other and may contribute to understand the complex interrelationships between the recombinant cell metabolism and the bioprocess environment towards more economic and robust processes design according to Quality by Design framework.

PMID- 27696722 TI - Development and validation of a capillary electrophoresis method for the characterization of sulfoethyl cellulose. AB - To characterize sulfoethyl cellulose el samples, a capillary electrophoresis method was developed and validated sulfoethyl cellulose el was hydrolyzed, and the resulting d-glucose derivatives were analyzed after reductive amination with 4-aminobenzoic acid using 150 mM boric acid, pH 9.5, as background electrolyte at 20 degrees C and a voltage of 28 kV. Peak identification was derived from capillary electrophoresis with mass spectrometry using 25 mM ammonia adjusted to pH 6.2 by acetic acid as electrolyte. Besides mono-, di-, and trisulfoethyl d glucose small amounts of disaccharides could be identified resulting from incomplete hydrolysis. The linearity of the borate buffer-based capillary electrophoresis method was evaluated using d-glucose in the concentration range of 3.9-97.5 MUg/mL, while limits of detection and quantification derived from the signal-to-noise ratio of 3 and 10 were 0.4 +/- 0.1 and 1.2 +/- 0.3 MUg/mL, respectively. Reproducibility and intermediate precision were determined using a hydrolyzed sulfoethyl cellulose el sample and ranged between 0.2 and 8.8% for migration times and between 0.3 and 10.4% for peak area. The method was applied to the analysis of the degree of substitution of synthetic sulfoethyl cellulose el samples obtained by variation of the synthetic process and compared to data obtained by elemental analysis. PMID- 27696720 TI - Association of prenatal lipid-based nutritional supplementation with fetal growth in rural Gambia. AB - Prenatal supplementation with protein-energy (PE) and/or multiple-micronutrients (MMNs) may improve fetal growth, but trials of lipid-based nutritional supplements (LNSs) have reported inconsistent results. We conducted a post-hoc analysis of non-primary outcomes in a trial in Gambia, with the aim to test the associations of LNS with fetal growth and explore how efficacy varies depending on nutritional status. The sample comprised 620 pregnant women in an individually randomized, partially blinded trial with four arms: (a) iron and folic acid (FeFol) tablet (usual care, referent group), (b) MMN tablet, (c) PE LNS, and (d) PE + MMN LNS. Analysis of variance examined unadjusted differences in fetal biometry z-scores at 20 and 30 weeks and neonatal anthropometry z-scores, while regression tested for modification of intervention-outcome associations by season and maternal height, body mass index, and weight gain. Despite evidence of between-arm differences in some fetal biometry, z-scores at birth were not greater in the intervention arms than the FeFol arm (e.g., birth weight z-scores: FeFol -0.71, MMN -0.63, PE -0.64, PE + MMN -0.62; group-wise p = .796). In regression analyses, intervention associations with birth weight and head circumference were modified by maternal weight gain between booking and 30 weeks gestation (e.g., PE + MMN associations with birth weight were +0.462 z-scores (95% CI [0.097, 0.826]) in the highest quartile of weight gain but -0.099 z scores (-0.459, 0.260) in the lowest). In conclusion, we found no strong evidence that a prenatal LNS intervention was associated with better fetal growth in the whole sample. PMID- 27696723 TI - Use of negative pressure wound therapy on malignant wounds - a case report and review of literature. AB - The presence of malignancy is considered a contraindication to the use of negative pressure wound therapy (NPWT) because of concerns that it may promote tumourigenesis and expedite metastasis. This notion is extrapolated from studies evaluating NPWT in normal tissues. Despite the absence of direct evidence, the use of this technology in malignant wounds is widely considered a contraindication. We present the case of a patient with treatment-resistant metastatic colon cancer, who developed a chronic abdominal wound with positive margins. A staged reconstruction using NPWT was performed and wound closure allowed the patient to meet eligibility criteria and enrol in a clinical trial for treatment of his oncological disease. Skin closure remained intact until the patient expired 6 months after the wound closure. This case, as well as others in the literature, demonstrated that the use of NPWT should not be considered an absolute contraindication in malignancy. Individualised approaches taking into account the patient's clinical scenario, the available evidence, as well as the risks and benefits of this technology are recommended. PMID- 27696725 TI - Integrated Exploitation of the Structural Diversity Space of Chemotherapy Drugs to Selectively Inhibit HER2 T798M Mutant in Lung Cancer. AB - An acquired T798M gatekeeper mutation in human epidermal growth factor receptor 2 (HER2) kinase can cause drug resistance to anti-HER2 chemotherapy drugs in lung cancer. Previously, the reversible pan-kinase inhibitor staurosporine has been found to selectively inhibit the HER2 T798M mutant over wild-type kinase, suggesting that the staurosporine scaffold is potentially to develop mutant selective inhibitors. Here, we systematically evaluated the chemical space of staurosporine scaffold-based compounds in response to HER2 T798M mutation at structural, energetic and molecular levels by using an integrated analysis strategy. With this strategy, we were able to identify several novel wild-type sparing inhibitors with high or moderate selectivity, which are comparable to or even better than that of the parent compound staurosporine. Molecular modeling and structural analysis revealed that noncovalent contacts can form between the side chain of mutated residue Met798 and selective inhibitor ligands, which may improve the favorable interaction energy between the kinase and inhibitor and reduce the unfavorable desolvation penalty upon the kinase-inhibitor binding. PMID- 27696724 TI - Comparative Assessment of the Different American College of Rheumatology/European League Against Rheumatism Remission Definitions for Rheumatoid Arthritis for Their Use as Clinical Trial End Points. AB - OBJECTIVE: The American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) have defined remission using Boolean- or index-based criteria (i.e., a Simplified Disease Activity Index [SDAI] score of <=3.3). We undertook this study to compare definitions of remission to inform choice of end points for future rheumatoid arthritis (RA) clinical trials, and we also included in our comparison the remission criterion of a score of <=2.8 on the Clinical Disease Activity Index (CDAI). METHODS: We performed post hoc analyses on clinical remission rates using data from 2 infliximab trials (the ASPIRE [Active Controlled Study of Patients Receiving Infliximab for the Treatment of Rheumatoid Arthritis of Early Onset] and ATTRACT [Anti-Tumor Necrosis Factor Trial in Rheumatoid Arthritis with Concomitant Therapy] trials) and 1 golimumab trial (the GO-FORWARD trial). We investigated stringency of the different remission definitions, their power to discriminate between active drug and comparator, and aspects of their internal and external validity. We also investigated population determinants of discriminatory power for a particular remission end point. RESULTS: In patients with early RA (the ASPIRE trial), ACR/EULAR Boolean, CDAI, and SDAI remission rates at 6-7 months were 4-6% for methotrexate (MTX) alone versus 11-14% for infliximab plus MTX. In patients with MTX-refractory active RA (the ATTRACT and GO-FORWARD trials), remission rates were <=1% for comparator (add-on of placebo) versus 4-6% for add-on of infliximab in the ATTRACT trial and <=3% for comparator (add-on of placebo) versus 11-13% for add-on of golimumab in the GO-FORWARD trial. Existing remission cut points of different measures were generally comparable, with the Boolean criteria being somewhat more stringent than the SDAI and CDAI criteria. Remission rates were similar across definitions, as was average statistical power (CDAI, 55.6%; Boolean, 59.9%; SDAI, 62.6%). CONCLUSION: Remission is an ambitious primary end point for RA clinical trials, to be reserved for selected scenarios based on power considerations. The ACR/EULAR definitions are interchangeable, with slightly higher stringency of Boolean criteria over index-based criteria. PMID- 27696726 TI - Parathyroid adenoma: a comprehensive biochemical and histological correlative study. AB - OBJECTIVE: To investigate the controversial relationship between preoperative calcium and parathyroid hormone levels and the dimensions and histological features of parathyroid adenoma in patients with primary hyperparathyroidism. STUDY DESIGN: Historical cohort. SETTING: Tertiary medical centre. SUBJECTS AND METHODS: Clinical and tumour-related data were collected from the medical files of all patients who underwent parathyroidectomy for primary hyperparathyroidism in 1996-2012. Preoperative blood parathyroid hormone and calcium levels and urine calcium levels were correlated with the size, weight and volume of the parathyroid adenoma. Pathohistological features were determined in a representative sample of archived paraffin-embedded sections and analysed by calcium or parathyroid hormone level (high/low) and adenoma weight (high/low). RESULTS: A total of 378 patients were included. There was a statistically significant direct correlation of preoperative calcium and parathyroid hormone levels with tumour dimensions and of tumour weight and chief-cell percentage. At a preoperative calcium level >11.5 mg/dL and parathyroid hormone (PTH) level >165 mg/dL, we predict that the adenoma would measure more than 2.7 g, 2.18 cm and volume of 3.59 cm3 . CONCLUSIONS: In patients with primary hyperparathyroidism, preoperative calcium and PTH levels may be predictive of parathyroid adenoma dimensions. PMID- 27696727 TI - Early Disease Activity or Clinical Response as Predictors of Long-Term Outcomes With Certolizumab Pegol in Axial Spondyloarthritis or Psoriatic Arthritis. AB - OBJECTIVE: Early identification of patients unlikely to achieve good long-term disease control with anti-tumor necrosis factor therapy in axial spondyloarthritis (SpA) and psoriatic arthritis (PsA) is important for physicians following treat-to-target recommendations. Here we assess associations between disease activity or clinical response during the first 12 weeks of treatment and attainment of treatment targets at week 48 in axial SpA and PsA patients receiving certolizumab pegol. METHODS: The relationship between disease activity or clinical response during the first 12 weeks of treatment and achievement of week-48 targets (for axial SpA: inactive disease based on Ankylosing Spondylitis Disease Activity Score [ASDAS] using the C-reactive protein [CRP] level, or Bath Ankylosing Spondylitis Disease Activity Index <2 with normal CRP level; and for PsA: minimal disease activity) was assessed post hoc using RAPID-axSpA and RAPID PsA trial data. RESULTS: A clear relationship between disease activity from week 2 to 12 and achievement of week-48 treatment targets was observed in both axial SpA and PsA populations. In axial SpA, week-48 ASDAS inactive disease was achieved by 0% of patients (0 of 21) with ASDAS very high disease activity at week 12, compared to 68% of patients (34 of 50) with week-12 ASDAS inactive disease. For PsA, week-48 minimal disease activity was achieved by 0% of patients (0 of 26) with Disease Activity Score in 28 joints (DAS28) using the CRP level >5.1 at week 12, compared to 73% of patients (57 of 78) with DAS28-CRP <2.6. Similar results were observed regardless of the disease activity measure used. Clinical response at week 12 also predicted week-48 outcomes, though to a lesser extent than disease activity. CONCLUSION: Using disease activity and the clinical response state during the first 12 weeks of certolizumab pegol treatment, it was possible to identify a subset of axial SpA and PsA patients unlikely to achieve long-term treatment goals. PMID- 27696728 TI - Association of Beta-Blocker Use With Less Prevalent Joint Pain and Lower Opioid Requirement in People With Osteoarthritis. AB - OBJECTIVE: Recent findings suggest that beta-adrenergic blockers have antinociceptive properties. The aim of this study was to compare levels of large joint pain between those taking adrenergic blockers and those taking other antihypertensive medications. METHODS: Data from the Genetics of Osteoarthritis and Lifestyle (GOAL) study, a secondary-care cohort of osteoarthritis (OA) patients, were used. Joint pain was assessed using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores in 873 individuals with symptomatic hip and/or knee OA and hypertension, who were taking >=1 prescription antihypertensive medications. The association between adrenergic blocker prescription and at least moderate joint pain (WOMAC score <75) and use of prescription analgesics was examined using binary logistic regression. Analyses were adjusted for age, sex, body mass index, knee or hip OA, history of joint replacement (at other joints), anxiety, and depression. RESULTS: The use of beta adrenergic blockers was associated with lower WOMAC pain scores and with a lower prevalence of joint pain after adjustment for demographic variables and comorbidity (adjusted odds ratio [ORadj ] for pain 0.68 [95% confidence interval (95% CI) 0.51, 0.92]; P < 0.011). No associations with pain were observed with use of alpha-blockers (ORadj for pain 0.94 [95% CI 0.55, 1.58]) or with any other class of antihypertensive medications. Prescription of beta-blockers was also associated negatively with opioid use (ORadj for opioids 0.73 [95% CI 0.54, 0.98]; P < 0.037) and with the use of prescription analgesics in general (ORadj for analgesics 0.74 [95% CI 0.56, 0.94]; P < 0.032). CONCLUSION: The use of beta blockers is associated with less joint pain and a lower use of opioids and other analgesics in individuals with symptomatic large-joint OA. This observation needs to be confirmed by other studies.

AB - A novel and simple supported ionic-liquid-based solid-phase extraction method for the determination of triazine herbicides in rice was developed. Glass slides were functionalized by an ionic liquid, 1-carboxyethyl-3-methylimidazolium chloride, and were used for the simultaneous extraction of seven triazine herbicides in rice samples. The effects of the type of extraction solvent, the extraction time, the type and volume of loading solvent, and the type of eluting solvent on the extraction efficiency were investigated and optimized. Under the optimum operation conditions, the limits of detection for seven triazine herbicides in rice samples obtained by high-performance liquid chromatography were 3.16-5.42 ng/g, which were lower than the maximum residue levels established by various organizations. The linear correlation coefficients were higher than 0.9975 in the concentration range of 0.015-1.08 MUg/g for the seven triazine herbicides. The recoveries of the seven triazine herbicides at the two concentration levels of 0.15 and 0.45 MUg/g are between 82.47 and 104.21%, with relative standard deviations of 0.69-9.19%. The intra- and inter-day (n = 5) precisions for all triazine herbicides at the spiked level of 0.30 MUg/g were 1.72-11.71%. PMID- 27696730 TI - The future of heart valve replacement: recent developments and translational challenges for heart valve tissue engineering. AB - Heart valve replacement is often the only solution for patients suffering from valvular heart disease. However, currently available valve replacements require either life-long anticoagulation or are associated with valve degeneration and calcification. Moreover, they are suboptimal for young patients, because they do not adapt to the somatic growth. Tissue-engineering has been proposed as a promising approach to fulfil the urgent need for heart valve replacements with regenerative and growth capacity. This review will start with an overview on the currently available valve substitutes and the techniques for heart valve replacement. The main focus will be on the evolution of and different approaches for heart valve tissue engineering, namely the in vitro, in vivo and in situ approaches. More specifically, several heart valve tissue-engineering studies will be discussed with regard to their shortcomings or successes and their possible suitability for novel minimally invasive implantation techniques. As in situ heart valve tissue engineering based on cell-free functionalized starter materials is considered to be a promising approach for clinical translation, this review will also analyse the techniques used to tune the inflammatory response and cell recruitment upon implantation in order to stir a favourable outcome: controlling the blood-material interface, regulating the cytokine release, and influencing cell adhesion and differentiation. In the last section, the authors provide their opinion about the future developments and the challenges towards clinical translation and adaptation of heart valve tissue engineering for valve replacement.

AB - OBJECTIVE: To examine the prevalence and incidence of cardiovascular (CV) risk factors, including hypertension, hyperlipidemia, diabetes mellitus (DM), and obesity among patients with psoriatic arthritis (PsA) and rheumatoid arthritis (RA) compared to the general population, and to examine the treatment of incident CV risk factors in PsA and RA compared to controls. METHODS: A cohort study was conducted within The Health Improvement Network, a medical record database in the UK, using data from 1994 to 2014. Patients ages 18-89 years with PsA or RA were matched to controls on practice and start date. The prevalence and incidence of CV risk factors identified by diagnostic codes were calculated. Cox proportional hazards models were used to examine the relative incidence of these CV risk factors. Finally, pharmacologic therapies for incident CV risk factors were examined. RESULTS: Study subjects included patients with PsA (n = 12,548), RA (n = 53,215), and controls (n = 389,269). The prevalence of all CV risk factors was significantly elevated in PsA. Only the prevalence of DM and obesity was increased in RA. Incidence of hypertension, hyperlipidemia, and DM was elevated in PsA and RA. Receipt of therapy within 1 year following incident diagnosis of CV risk factors was not substantially different between the groups; approximately 85%, 65%, and 45% of patients received prescriptions for hypertension, hyperlipidemia, and DM, respectively. CONCLUSION: Patients with PsA have an increased prevalence of CV risk factors, and both patients with PsA and patients with RA have increased incidence of a new diagnosis of CV risk factors. Pharmacologic treatment of CV risk factors in patients with PsA and RA was similar to controls in the UK. PMID- 27696732 TI - Do Short and Sustained Periods of American College of Rheumatology/European League Against Rheumatism Remission Predict Functional and Radiographic Outcome in Early Rheumatoid Arthritis Patients With Low Overall Damage Progression? AB - OBJECTIVE: To investigate whether remission at single and consecutive visits predicts good outcome in early rheumatoid arthritis (RA). METHODS: The presence of remission according to American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) and other criteria (Boolean clinical, Clinical Disease Activity Index, Disease Activity Score [DAS], DAS in 28 joints, and Routine Assessment of Patient Index Data 3) was assessed in early RA patients during the first year of the Combination Therapy for Rheumatoid Arthritis light trial. Likelihood ratios were used to assess whether meeting the remission criteria at single visits (13, 26, 39, or 52 weeks) and consecutive visits (13 and 26, 26 and 39, or 39 and 52 weeks) predicted good outcome in the second year (52-104 weeks). Good outcome was defined for function (Health Assessment Questionnaire score consistently <=0.5 and no deterioration), radiographic damage progression (no deterioration in Sharp/van der Heijde scores), and both ("overall good outcome"). RESULTS: Of the original 164 trial patients, 144 had evaluable data. In the second year, good functional outcome was observed in 35%, good radiographic outcome in 79%, and both in 28% of the patients. Almost all criteria predicted good functional and good overall outcome, at both single and consecutive visits; only single DAS remission did not significantly predict good overall outcome (P = 0.07). Sustained remission periods resulted in higher likelihood ratios than remission at single visits. None of the criteria predicted good radiographic outcome. CONCLUSION: Early RA patients who reached remission according to ACR/EULAR and other criteria during short or sustained periods were likely to retain good physical function in the subsequent months. Sustained remission periods were a stronger predictor than remission at single visits. However, in the setting of low overall damage progression, (sustained) remission was not predictive of good radiographic outcome. PMID- 27696733 TI - Identification of LmUAP1 as a 20-hydroxyecdysone response gene in the chitin biosynthesis pathway from the migratory locust, Locusta migratoria. AB - In Locusta migratoria, we found that two chitin biosynthesis genes, UDP N acetylglucosamine pyrophosphorylase gene LmUAP1 and chitin synthase gene LmCHS1, are expressed mainly in the integument and are responsible for cuticle formation. However, whether these genes are regulated by 20-hydroxyecdysone (20E) is still largely unclear. Here, we showed the developmental expression pattern of LmUAP1, LmCHS1 and the corresponding 20E titer during the last instar nymph stage of locust. RNA interference (RNAi) directed toward a common region of the two isoforms of LmEcR (LmEcRcom) reduced the expression level of LmUAP1, while there was no difference in the expression of LmCHS1. Meantime, injection of 20E in vivo induced the expression of LmUAP1 but not LmCHS1. Further, we found injection based RNAi of LmEcRcom resulted in 100% mortality. The locusts failed to molt with no apolysis, and maintained in the nymph stage until death. In conclusion, our preliminary results indicated that LmUAP1 in the chitin biosynthesis pathway is a 20E late-response gene and LmEcR plays an essential role in locust growth and development, which could be a good potential target for RNAi-based pest control. PMID- 27696734 TI - Synthesis and evaluation of anti-inflammatory properties of silver nanoparticle suspensions in experimental colitis in mice. AB - The aim of our study was to investigate the effect of newly developed silver nanoparticle aqueous suspensions NanoAg1 and NanoAg2 in the mouse models mimicking ulcerative colitis and Crohn's disease. NanoAg1 and NanoAg2 were synthesized in aqueous medium with the involvement of tannic acid. To elucidate their anti-inflammatory activity, semi-chronic mouse models of inflammation induced by dextrane sulfate sodium addition to drinking water and intracolonic (i.c.) administration of 2,4,6-trinitrobenzenesulfonic acid were used. NanoAg1 and NanoAg2 (500 mg/dm3, 100 MUl/animal, i.c., once daily) significantly ameliorated colitis in dextrane sulfate sodium- and 2,4,6-trinitrobenzenesulfonic acid-induced mouse models of colonic inflammation, as indicated by reduced macroscopic, ulcer and microscopic scores. The anti-inflammatory effect was dependent on the shape and diameter of silver nanoparticles, as indicated by weaker effect of NanoAg1 than NanoAg2. In addition, administration of NanoAg2, but not NanoAg1, modulated colonic microbiota, as indicated by reduced number of Escherichia coli and Clostridium perfringens, and increased number of Lactobacillus sp. Summarizing, NanoAg1 and NanoAg2 after administered i.c. effectively alleviate colitis in experimental models of ulcerative colitis and Crohn's disease in mice. Therefore, NanoAg1 and NanoAg2 administered i.c. have the potential to become valuable agents for the treatment of inflammatory bowel diseases. PMID- 27696735 TI - Eight-Year Retention Rate of First-Line Tumor Necrosis Factor Inhibitors in Spondyloarthritis: A Multicenter Retrospective Analysis. AB - OBJECTIVE: To evaluate the 8-year survival of the first tumor necrosis factor inhibitor (TNFi) in patients with axial spondyloarthritis (SpA) or psoriatic arthritis (PsA), identify the predictive factors for withdrawal, and compare the discontinuation rates for infliximab, etanercept, and adalimumab. METHODS: We evaluated PsA and axial SpA patients treated with a first-line TNFi between 2005 and 2015 at 4 Italian tertiary centers. Eight-year drug survival was calculated by the Kaplan-Meier method, and risk for discontinuation among treatment groups compared by stratified log-rank test. Univariate and multivariate Cox proportional hazard models were developed to examine predictors of withdrawal. RESULTS: Of 614 patients (316 axial with SpA, 298 with PsA), 203 received adalimumab, 131 etanercept, and 280 infliximab, with similar frequencies in axial SpA and PsA subgroups. The cumulative 8-year retention rate in the whole population was 55.1% (57.2% and 51.9% for axial SpA and PsA, respectively; P = not significant). No significant differences were observed in drug persistence among individual TNFi in either group. Male sex (hazard ratio [HR] 0.595 [95% confidence interval (95% CI) 0.405-0.875]; P = 0.008) and concomitant methotrexate use (HR 0.648 [95% CI 0.426-0.985]; P = 0.042) were associated with a lower risk of withdrawal in PsA. High baseline Bath Ankylosing Spondylitis Disease Activity Index (HR 0.9842 [95% CI 0.9708-0.9980]; P = 0.028) was associated with a lower risk of withdrawal in axial SpA. No difference was found in the comparative analysis of reasons for discontinuation between PsA and axial SpA. CONCLUSION: We reported that the real-life 8-year retention rate of the first TNFi in axial SpA and PsA is greater than 50%, with no significant differences between axial SpA and PsA, irrespective of the individual TNFi. PMID- 27696736 TI - The impact of personality on person-centred care: a study of care staff in Swedish nursing homes. AB - AIM AND OBJECTIVE: In this study, we explore how personal and situational factors relate to the provision of person-centred care (PCC) in nursing homes. Specifically, we focus on the relationship between the care staff's personality traits and provision of PCC and to what extent perceptions of the working environment influences this relationship. BACKGROUND: The ultimate goal of elderly care is to meet the older person's needs and individual preferences (PCC). Interpersonal aspects of care and the quality of relationship between the care staff and the older person are therefore central in PCC. DESIGN AND METHODS: A cross-sectional Swedish sample of elderly care staff (N = 322) completed an electronic survey including measures of personality (Mini-IPIP) and person centred care (Individualized Care Inventory, ICI). A principal component analysis was conducted on the ICI-data to separate the user orientation (process quality) of PCC from the preconditions (structure quality) of PCC. RESULTS: Among the five factors of personality, neuroticism was the strongest predictor of ICI user orientation. ICI preconditions significantly mediated this relationship, indicating the importance of a supportive working environment. In addition, stress was introduced as a potential explanation and was shown to mediate the impact of neuroticism on ICI preconditions. CONCLUSIONS: Personality traits have a significant impact on user orientation, and the perception of a supportive and stress free working environment is an important prerequisite for achieving high quality person-centred elderly care. IMPLICATIONS FOR PRACTICE: Understanding how personality is linked to the way care staff interacts with the older person adds a new perspective on provision of person-centred elderly care. PMID- 27696738 TI - Transcriptome analysis of sugar beet root maggot (Tetanops myopaeformis) genes modulated by the Beta vulgaris host. AB - Sugar beet root maggot (SBRM, Tetanops myopaeformis von Roder) is a major but poorly understood insect pest of sugar beet (Beta vulgaris L.). The molecular mechanisms underlying plant defense responses are well documented, however, little information is available about complementary mechanisms for insect adaptive responses to overcome host resistance. To date, no studies have been published on SBRM gene expression profiling. Suppressive subtractive hybridization (SSH) generated more than 300 SBRM ESTs differentially expressed in the interaction of the pest with a moderately resistant (F1016) and a susceptible (F1010) sugar beet line. Blast2GO v. 3.2 search indicated that over 40% of the differentially expressed genes had known functions, primarily driven by fruit fly D. melanogaster genes. Expression patterns of 18 selected EST clones were confirmed by RT-PCR analysis. Gene Ontology (GO) analysis predicted a dominance of metabolic and catalytic genes involved in the interaction of SBRM with its host. SBRM genes functioning during development, regulation, cellular process, signaling and under stress conditions were annotated. SBRM genes that were common or unique in response to resistant or susceptible interactions with the host were identified and their possible roles in insect responses to the host are discussed. PMID- 27696737 TI - Highly polygenic architecture of antidepressant treatment response: Comparative analysis of SSRI and NRI treatment in an animal model of depression. AB - Response to antidepressant (AD) treatment may be a more polygenic trait than previously hypothesized, with many genetic variants interacting in yet unclear ways. In this study we used methods that can automatically learn to detect patterns of statistical regularity from a sparsely distributed signal across hippocampal transcriptome measurements in a large-scale animal pharmacogenomic study to uncover genomic variations associated with AD. The study used four inbred mouse strains of both sexes, two drug treatments, and a control group (escitalopram, nortriptyline, and saline). Multi-class and binary classification using Machine Learning (ML) and regularization algorithms using iterative and univariate feature selection methods, including InfoGain, mRMR, ANOVA, and Chi Square, were used to uncover genomic markers associated with AD response. Relevant genes were selected based on Jaccard distance and carried forward for gene-network analysis. Linear association methods uncovered only one gene associated with drug treatment response. The implementation of ML algorithms, together with feature reduction methods, revealed a set of 204 genes associated with SSRI and 241 genes associated with NRI response. Although only 10% of genes overlapped across the two drugs, network analysis shows that both drugs modulated the CREB pathway, through different molecular mechanisms. Through careful implementation and optimisations, the algorithms detected a weak signal used to predict whether an animal was treated with nortriptyline (77%) or escitalopram (67%) on an independent testing set. The results from this study indicate that the molecular signature of AD treatment may include a much broader range of genomic markers than previously hypothesized, suggesting that response to medication may be as complex as the pathology. The search for biomarkers of antidepressant treatment response could therefore consider a higher number of genetic markers and their interactions. Through predominately different molecular targets and mechanisms of action, the two drugs modulate the same Creb1 pathway which plays a key role in neurotrophic responses and in inflammatory processes.

PMID- 27696739 TI - Seven-Year Outcomes of the Silicone Arthroplasty in Rheumatoid Arthritis Prospective Cohort Study. AB - OBJECTIVE: Rheumatoid arthritis (RA) causes destruction of the metacarpophalangeal (MCP) joints, leading to hand deformities, pain, and loss of function. This study prospectively assessed long-term functional and health related quality-of-life outcomes in RA patients with severe deformity at the MCP joints. METHODS: RA patients between ages 18 to 80 years with severe deformity at the MCP joints were referred to 1 of the 3 study sites. Subjects who elected to undergo silicone metacarpophalangeal joint arthroplasty (SMPA) while continuing with medical management were followed in the SMPA cohort. Subjects who elected to continue with medical management alone without surgery were followed in the non SMPA cohort. Objective measurements included grip and pinch strength as well as arc of motion, ulnar drift, and extensor lag of the MCP joints. Patient-reported outcomes included the Michigan Hand Questionnaire (MHQ) and the Arthritis Impact Measurement Scales questionnaire. Radiographs of SMPA implants were assessed and graded as intact, deformed, or fractured. RESULTS: MHQ scores showed large improvements post-SMPA, and baseline-adjusted expected outcomes in the SMPA group were significantly better at year 7 in function, aesthetics, satisfaction, and overall score compared to non-SMPA. SMPA subjects did not improve in grip or pinch strength, but achieved significant improvement and maintained the improvement long term in ulnar drift and extensor lag. CONCLUSION: Benefits of the SMPA procedure are maintained over 7 years with low rates of implant fracture or deformity. Non-SMPA patients remained stable in their hand function over the 7 year study duration. PMID- 27696740 TI - Exploring the relationship between cortical GABA concentrations, auditory gamma band responses and development in ASD: Evidence for an altered maturational trajectory in ASD. AB - Autism spectrum disorder (ASD) is hypothesized to arise from imbalances between excitatory and inhibitory neurotransmission (E/I imbalance). Studies have demonstrated E/I imbalance in individuals with ASD and also corresponding rodent models. One neural process thought to be reliant on E/I balance is gamma-band activity (Gamma), with support arising from observed correlations between motor, as well as visual, Gamma and underlying GABA concentrations in healthy adults. Additionally, decreased Gamma has been observed in ASD individuals and relevant animal models, though the direct relationship between Gamma and GABA concentrations in ASD remains unexplored. This study combined magnetoencephalography (MEG) and edited magnetic resonance spectroscopy (MRS) in 27 typically developing individuals (TD) and 30 individuals with ASD. Auditory cortex localized phase-locked Gamma was compared to resting Superior Temporal Gyrus relative cortical GABA concentrations for both children/adolescents and adults. Children/adolescents with ASD exhibited significantly decreased GABA+/Creatine (Cr) levels, though typical Gamma. Additionally, these children/adolescents lacked the typical maturation of GABA+/Cr concentrations and gamma-band coherence. Furthermore, children/adolescents with ASD additionally failed to exhibit the typical GABA+/Cr to gamma-band coherence association. This altered coupling during childhood/adolescence may result in Gamma decreases observed in the adults with ASD. Therefore, individuals with ASD exhibit improper local neuronal circuitry maturation during a childhood/adolescence critical period, when GABA is involved in configuring of such circuit functioning. Provocatively a novel line of treatment is suggested (with a critical time window); by increasing neural GABA levels in children/adolescents with ASD, proper local circuitry maturation may be restored resulting in typical Gamma in adulthood.

PMID- 27696741 TI - Inflammatory Gene Expression Profile and Defective Interferon-gamma and Granzyme K in Natural Killer Cells From Systemic Juvenile Idiopathic Arthritis Patients. AB - OBJECTIVE: Systemic juvenile idiopathic arthritis (JIA) is an immunoinflammatory disease characterized by arthritis and systemic manifestations. The role of natural killer (NK) cells in the pathogenesis of systemic JIA remains unclear. The purpose of this study was to perform a comprehensive analysis of NK cell phenotype and functionality in patients with systemic JIA. METHODS: Transcriptional alterations specific to NK cells were investigated by RNA sequencing of highly purified NK cells from 6 patients with active systemic JIA and 6 age-matched healthy controls. Cytokines (NK cell-stimulating and others) were quantified in plasma samples (n = 18). NK cell phenotype and cytotoxic activity against tumor cells were determined (n = 10), together with their interferon-gamma (IFNgamma)-producing function (n = 8). RESULTS: NK cells from the systemic JIA patients showed an altered gene expression profile compared to cells from the healthy controls, with enrichment of immunoinflammatory pathways, increased expression of innate genes including TLR4 and S100A9, and decreased expression of immune-regulating genes such as IL10RA and GZMK. In the patients' plasma, interleukin-18 (IL-18) levels were increased, and a decreased ratio of IFNgamma to IL-18 was observed. NK cells from the patients exhibited specific alterations in the balance of inhibitory and activating receptors, with decreased killer cell lectin-like receptor G1 and increased NKp44 expression. Although NK cells from the patients showed increased granzyme B expression, consistent with intact cytotoxicity and degranulation against a tumor cell line, decreased granzyme K expression in CD56bright NK cells and defective IL-18-induced IFNgamma production and signaling were demonstrated. CONCLUSION: NK cells are active players in the inflammatory environment typical of systemic JIA. Although their cytotoxic function is globally intact, subtle defects in NK-related pathways, such as granzyme K expression and IL-18-driven IFNgamma production, may contribute to the immunoinflammatory dysregulation in this disease. PMID- 27696743 TI - Infant feeding practices in a South African birth cohort-A longitudinal study. AB - Childhood malnutrition is highly prevalent in low- and middle-income countries. The choices of complementary foods, which are important in infant nutrition, are poorly described in this setting. We investigated infant feeding practices in a South African birth cohort, the Drakenstein Child Health Study. Longitudinal feeding data were collected from March 2012 to March 2015. Feeding practices at birth, 6-10 and 14 weeks and 6, 9, and 12 months, were investigated using food frequency questionnaires. Anthropometry was measured at birth and 12 months. The quality of the diet was analyzed using the World Health Organization infant and young child feeding indicators. Regression models were used to explore associations between feeding and growth outcomes at 1 year. Exclusive breastfeeding for 6 months was low (13%), and 19% of infants were introduced to solid foods before 4 months. There was high daily consumption of processed meat (56%) and inappropriate foods such as fruit juice (82%), soft drinks (54%), and refined sugary foods (51%) at 1 year. Dietary diversity and consumption of iron rich foods were low at 6 months (5% and 3%, respectively) but higher by 12 months (75% and 78%). Longer duration of exclusive breastfeeding was associated with a lower height-for-age z-score at 1 year. Several dietary deficits and a rising trend in the consumption of inappropriate nutritionally poor foods were identified. These findings raise concern about poor dietary practices and the impact on child and long-term health. PMID- 27696744 TI - Reply. PMID- 27696742 TI - Genome-Wide Association Study of Radiographic Knee Osteoarthritis in North American Caucasians. AB - OBJECTIVE: A major barrier to genetic studies of osteoarthritis (OA) is the need to obtain large numbers of individuals with standardized radiographic evaluations for OA. To address this gap, we performed a genome-wide association study (GWAS) of radiographically defined tibiofemoral knee OA in 3,898 cases and 3,168 controls from 4 well-characterized North American cohorts, and we performed replication analysis of previously reported OA loci. METHODS: We performed meta analysis using a 2-stage design. Stage 1 (discovery) consisted of a GWAS meta analysis of radiographic knee OA carried out in the Osteoarthritis Initiative and the Johnston County Osteoarthritis Project. Knee OA was defined as definite osteophytes and possible joint space narrowing or total joint replacement in one or both knees. Stage 2 (validation) was performed in the Multicenter Osteoarthritis Study and the Genetics of Osteoarthritis study. We genotyped lead meta-analysis variants (P <= 1 * 10-4 ) from stage 1 and tested the association between these variants and knee OA. We then combined results from all cohorts in a meta-analysis. RESULTS: Lead variants from stage 1, representing 49 unique loci, were analyzed in stage 2; none met genome-wide significance in the combined analysis of stage 1 and stage 2. We validated 1 locus (rs4867568 near LSP1P3) with nominal significance (P < 0.05), which was also our top finding in the combined meta-analysis (odds ratio [OR] 0.84 [95% confidence interval (95% CI) 0.79-0.91], P = 3.02 * 10-6 ). We observed nominally significant associations (P < 0.05) with 3 previously reported OA loci: rs143383 in GDF5 (OR 1.12 [95% CI 1.04-1.21], P = 2.13 * 10-3 ), rs835487 in CHST11 (OR 0.93 [95% CI 0.85-0.99], P = 0.03), and rs8044769 in FTO (OR 1.10 [95% CI 1.03-1.19], P = 6.13 * 10-3 ). CONCLUSION: These findings provide suggestive evidence of a novel knee OA locus and confirm previously reported associations in GDF5, CHST11, and FTO. PMID- 27696746 TI - Cam Deformity and Acetabular Dysplasia as Risk Factors for Hip Osteoarthritis. AB - OBJECTIVE: Cam deformity and acetabular dysplasia have been recognized as relevant risk factors for hip osteoarthritis (OA) in a few prospective studies with limited sample sizes. To date, however, no evidence is available from prospective studies regarding whether the magnitude of these associations differs according to sex, body mass index (BMI), and age. METHODS: Participants in the Rotterdam Study cohort including men and women ages 55 years or older without OA at baseline (n = 4,438) and a mean follow-up of 9.2 years were included in the study. Incident radiographic OA was defined as a Kellgren/Lawrence grade of >=2 or a total hip replacement at follow-up. Alpha and center-edge angles were measured to determine the presence of cam deformity and acetabular dysplasia/pincer deformity, respectively. Odds ratios (ORs) were calculated to assess the associations between both deformities and the development of OA. RESULTS: Subjects with cam deformity (OR 2.11, 95% confidence interval [95% CI] 1.55-2.87) and those with acetabular dysplasia (OR 2.19, 95% CI 1.50-3.21) had a 2-fold increased risk of developing OA compared with subjects without deformity, while pincer deformity did not increase the risk of OA. Stratification analyses showed that the associations of cam deformity and acetabular dysplasia with OA were driven by younger individuals, whereas BMI did not influence the associations. Female sex appears to modify the risk of hip OA related to acetabular dysplasia. CONCLUSION: Individuals with cam deformity and those with acetabular dysplasia are predisposed to OA; these associations were independent of other well-known risk factors. Interestingly, both deformities predisposed to OA only in relatively young individuals. Therefore, early identification of these conditions is important. PMID- 27696745 TI - Cardiovascular parameters of chest CT scan in estimating pulmonary arterial pressure in patients with pulmonary hypertension. AB - OBJECTIVE: To develop a formula to compute mean pulmonary arterial pressure (MPAP) by chest computerized tomography (CT), and to verify its accuracy and reliability. METHODS: Eighty-five patients who had taken chest CT and right heart catheterization (RHC) were recruited. The pulmonary arterial systolic pressure (PASP), pulmonary arterial diastolic pressure (PADP), and MPAP of each subject were measured and recorded by RHC. The diameters of the ascending aorta (dAA), descending aorta (dDA) and main pulmonary artery (dMPA), Cobb angle, diameters of right ventricle (dRV), diameters of left ventricle (dLV) were measured by means of chest CT scans. Systolic blood pressure (SBP) was measured by using electronic sphygmomanometer. A linear regression equation was generated in 56 patients to estimate PAP based on chest CT values, 29 patients were used to test the accuracy of the formula. RESULTS: The computed equation for analyzing MPAP is: MPAP = 9.011 + 34.195 * dMPA/dAA - 0.319 * SBP + 0.402 * Cobb angle. AUC of equation with three variables (dMPA/dAA, SBP, and Cobb angle) was 0.923 with 95% CI (0.863 0.982). The mean +/- SD of predicted values and RHC values had no statistical difference. CONCLUSIONS: Ratio of dMAP/dAA, Cobb angle, and SBP can be reliably used to estimate MPAP and predict severity of PH. PMID- 27696747 TI - Endobronchial involvement as an extremely rare manifestation of the Waldenstrom's disease. AB - Pulmonary infiltration is an infrequent organ involvement in Waldenstrom's disease (WD). Diffuse infiltration, isolated parenchymatous nodules, and pleural effusion are the most common manifestations of WD, while endobronchial mass is extremely rare. We present a case report of a 66-year-old man with a long standing history of WD, who developed febrile neutropenia after therapy with rituximab, cyclophosphamide, and dexamethasone. X-ray and CT scan showed consolidation consistent with right-sided pneumonia. Surprisingly, bronchoscopy revealed an endobronchial tumor obstructing the right lower lobe (RLL) and two smaller granulations. Biopsies were obtained and recanalization of the RLL bronchus was performed. Immunohistological staining of the samples was consistent with lymphoplasmacytic lymphoma. Despite the change in therapy the patient died 6 weeks later. A review of published literature revealed only two case reports of endobronchial involvement in WD to this day. While one of the case reports described a patient with diffuse submucosal infiltration of the airways, the other one presented a patient with bronchus-obstructing tumor similar to the case reported here. PMID- 27696750 TI - Mediating Effect of Changes in Hand Impairments on Hand Function in Patients With Rheumatoid Arthritis: Exploring the Mechanisms of an Effective Exercise Program. AB - OBJECTIVE: To determine whether the effect of the Strengthening and Stretching for Rheumatoid Arthritis of the Hand (SARAH) exercise program on hand function was mediated by changes in the proposed active ingredients: strength, dexterity, and/or range of motion. METHODS: The SARAH intervention included exercises hypothesized to improve potential mediators of grip strength, pinch strength, wrist flexion, wrist extension, finger flexion, finger extension, thumb opposition, and dexterity, which would theoretically improve self-reported hand function. All variables were measured at baseline and at 4 and 12 months. Structural equation modeling was used to assess mediation on change in hand function via change in potential mediators. RESULTS: Change in grip strength partially mediated change in hand function. Grip strength mediated 19.4% (95% confidence interval 0.9%, 37.8%) of the treatment effect. CONCLUSION: Improvements in grip strength at 4 months are likely to mediate improved hand function at 12 months. The role of joint mobility exercises is less clear and is likely influenced by the choice of measurement tools for both mobility and function outcomes. More robust measurements of wrist and hand mobility for patients with rheumatoid arthritis may be necessary to determine the relationship between this variable and self-reported hand function. Using a large trial data set, we have demonstrated that techniques used to target grip strength are key active ingredients of the SARAH exercise program and mediate its effect. PMID- 27696748 TI - PDGF is a potent initiator of bone formation in a tissue engineered model of pathological ossification. AB - Heterotopic ossification (HO) is a debilitating condition defined by the rapid formation of bone in soft tissues. What makes HO fascinating is first the rate at which bone is deposited, and second the fact that this bone is structurally and compositionally similar to that of a healthy adult. If the mechanisms governing HO are understood, they have the potential to be exploited for the development of potent osteoinductive therapies. With this aim, a tissue-engineered skeletal muscle was used model to better understand the role of inflammation on this debilitating phenomenon. It was shown that myoblasts could be divided into two distinct populations: myogenic cells and undifferentiated 'reserve' cells. Gene expression analysis of myogenic and osteoregulatory markers confirmed that 'reserve' cells were primed for osteogenic differentiation but had a reduced capacity for myogenesis. Osteogenic differentiation was significantly enhanced in the presence of platelet-derived growth factor (PDGF)-BB and bone morphogenetic protein 2 (BMP2), and correlated with conversion to a Sca-1+ /CD73+ phenotype. Alizarin red staining showed that PDGF-BB promoted significantly more mineral deposition than BMP2. Finally, it was shown that PDGF-induced mineralization was blocked in the presence of the pro-inflammatory cytokines tumour necrosis factor alpha and interleukin 1. In conclusion, the present study identified that PDGF-BB is a potent osteoinductive factor in a model of tissue-engineered skeletal muscle, and that the osteogenic capacity of this protein was modulated in the presence of pro-inflammatory cytokines. These findings reveal a possible mechanism by which HO develops following trauma. Importantly, these findings have implications for the induction and control of bone formation for regenerative medicine. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - In human spermatozoa, protein kinases have a role in the acrosome reaction (AR) induced by a variety of stimuli. However, there is disagreement or a lack of information regarding the role of protein kinases and phosphatases in the progesterone (P)-induced increase in intracellular calcium concentration ([Ca2+ ]i ). In addition, there are no studies regarding the role of Ser/Thr and Tyr phosphatases and there are contradictory results regarding the role of Tyr kinases in the P-induced acrosome reaction. Here, we performed a simultaneous evaluation of the involvement of protein kinases and phosphatases in the P induced acrosome reaction and in the P-induced calcium influx. Motile spermatozoa were capacitated for 18 h and different aliquots were allocated to treated or control groups and then evaluated for their ability to undergo the acrosome reaction and to increase [Ca2+ ]i in response to P. The acrosome reaction was evaluated using Pisum sativum agglutinin (PSA)-FITC, and [Ca2+ ]i was evaluated using fura 2AM. At all of the concentrations tested, PKA inhibitors significantly reduced the percentage of the P-induced acrosome reaction (p < 0.001). However, only the highest concentrations of PKA inhibitors reduced the P-induced calcium influx; lower concentrations of PKA inhibitors did not affect it. Similar results were apparent for PKC inhibitors and for tyrosine kinase inhibitors. None of the Ser/Thr phosphatase inhibitors affected the P-induced acrosome reaction or the P induced calcium influx, except for the PP2B inhibitors that significantly reduced the P-induced acrosome reaction without affecting calcium influx. Finally, the protein tyrosine phosphatase inhibitors significantly blocked the P-induced acrosome reaction and reduced the amplitude of the P-induced calcium transient (p < 0.001) as well as the amplitude of the plateau phase (p < 0.01). The data suggest that protein kinases and possibly PP2B have a role on the acrosome reaction at some point downstream of calcium entry and that Tyr phosphatases have a role on the acrosome reaction upstream of calcium entry.

AB - Acquired social disinhibition refers to a debilitating behavioural syndrome commonly reported after a severe traumatic brain injury (TBI) and is characterized by inappropriate social behaviour, often described as immaturity and insensitivity towards others. These behaviours can have enduring effects on the social capability of the individual and their relationships with others. However, research into socially disinhibited behaviour after TBI has been thwarted by a lack of consensus in the literature on definition and measurement. This review provides an overview of our current understanding of the definition, measurement, prevalence, associated outcomes, neuropathology, and underlying mechanisms of social disinhibition after TBI. In addition, suggestions are made for future research to further our understanding of this syndrome with the eventual aim of rehabilitating problematic behaviours. It is concluded that an improved understanding of what causes disinhibited behaviour after TBI will be necessary for the development of effective treatment strategies aimed at the rehabilitation of underlying impairments. PMID- 27696751 TI - In Vivo Role of Neutrophil Extracellular Traps in Antiphospholipid Antibody Mediated Venous Thrombosis. AB - OBJECTIVE: Antiphospholipid syndrome (APS) is a leading acquired cause of thrombotic events. Although antiphospholipid antibodies have been shown to promote thrombosis in mice, the role of neutrophils has not been explicitly studied. The aim of this study was to characterize neutrophils in the context of a new model of antiphospholipid antibody-mediated venous thrombosis. METHODS: Mice were administered fractions of IgG obtained from patients with APS. At the same time, blood flow through the inferior vena cava was reduced by induction of stenosis. Resulting thrombi were characterized for size and neutrophil content. Circulating factors and the vessel wall were also assessed. RESULTS: As measured by both thrombus weight and thrombosis frequency, mice treated with IgG from patients with APS (APS IgG) demonstrated exaggerated thrombosis as compared with control IgG-treated mice. Thrombi in mice treated with APS IgG were enriched for citrullinated histone H3 (a marker of neutrophil extracellular traps [NETs]). APS IgG-treated mice also demonstrated elevated levels of circulating cell-free DNA and human IgG bound to the neutrophil surface. In contrast, circulating neutrophil numbers and markers of vessel wall activation were not appreciably different between APS IgG-treated mice and control mice. Treatment with either DNase (which dissolves NETs) or a neutrophil-depleting antibody reduced thrombosis in APS IgG-treated mice to the level in control mice. CONCLUSION: These data support a mechanism whereby circulating neutrophils are primed by antiphospholipid antibodies to accelerate thrombosis. This line of investigation suggests new, immunomodulatory approaches for the treatment of APS. PMID- 27696754 TI - Reduction in Spinal Radiographic Progression in Ankylosing Spondylitis Patients Receiving Prolonged Treatment With Tumor Necrosis Factor Inhibitors. AB - OBJECTIVE: To evaluate the course of spinal radiographic progression for up to 8 years of followup in a large cohort of ankylosing spondylitis (AS) patients treated with tumor necrosis factor (TNF) inhibitors. METHODS: Consecutive patients from the Groningen Leeuwarden AS cohort starting TNF inhibitors between 2004 and 2012 were included. Baseline and biannual radiographs were randomized with radiographs of TNF-naive AS patients and scored in chronologic order according to modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). The course of radiographic progression (linear or nonlinear) was investigated using generalized estimating equations. Primary analysis was performed in patients with complete data over 4, 6, and 8 years of followup. Sensitivity analysis was performed after single linear imputation of missing radiographic data and after adjusting for patient characteristics with possible influence on radiographic progression. RESULTS: At baseline, median mSASSS of 210 included AS patients was 2.8 (interquartile range 0.0-12.0), mean +/- SD mSASSS 10.0 +/- 15.5. During the first 4 years, radiographic progression followed a linear course (estimated mean progression rate was 1.7 for 0-2 and 2-4 years). A deflection from a linear course was found in patients with complete and imputed data over 6 and 8 years. The estimated mean 2-year progression rate reduced from 2.3 to 0.8 in patients with complete 8-year data. The same pattern was found after adjustment for baseline mSASSS scores, presence of syndesmophytes, sex, HLA-B27 status, age, symptom duration, smoking duration, body mass index, disease activity, and nonsteroidal antiinflammatory drug use. CONCLUSION: This observational cohort study in AS patients receiving long-term TNF inhibitors showed a reduction in spinal radiographic progression after more than 4 years of followup. PMID- 27696755 TI - Rheumatology Informatics System for Effectiveness: A National Informatics-Enabled Registry for Quality Improvement. AB - OBJECTIVE: The Rheumatology Informatics System for Effectiveness (RISE) is a national electronic health record (EHR)-enabled registry. RISE passively collects data from EHRs of participating practices, provides advanced quality measurement and data analytic capacities, and fulfills national quality reporting requirements. Here we report the registry's architecture and initial data, and we demonstrate how RISE is being used to improve the quality of care. METHODS: RISE is a certified Centers for Medicare and Medicaid Services Qualified Clinical Data Registry, allowing collection of data without individual patient informed consent. We analyzed data between October 1, 2014 and September 30, 2015 to characterize initial practices and patients captured in RISE. We also analyzed medication use among rheumatoid arthritis (RA) patients and performance on several quality measures. RESULTS: Across 55 sites, 312 clinicians contributed data to RISE; 72% were in group practice, 21% in solo practice, and 7% were part of a larger health system. Sites contributed data on 239,302 individuals. Among the subset with RA, 34.4% of patients were taking a biologic or targeted synthetic disease-modifying antirheumatic drug (DMARD) at their last encounter, and 66.7% were receiving a nonbiologic DMARD. Examples of quality measures include that 55.2% had a disease activity score recorded, 53.6% a functional status score, and 91.0% were taking a DMARD in the last year. CONCLUSION: RISE provides critical infrastructure for improving the quality of care in rheumatology and is a unique data source to generate new knowledge. Data validation and mapping are ongoing and RISE is available to the research and clinical communities to advance rheumatology.

PMID- 27696756 TI - Anti-Interleukin-6 Receptor Tocilizumab for Severe Juvenile Idiopathic Arthritis Associated Uveitis Refractory to Anti-Tumor Necrosis Factor Therapy: A Multicenter Study of Twenty-Five Patients. AB - OBJECTIVE: To assess the efficacy of tocilizumab (TCZ) for the treatment of juvenile idiopathic arthritis (JIA)-associated uveitis. METHODS: We conducted a multicenter study of patients with JIA-associated uveitis that was refractory to conventional immunosuppressive drugs and anti-tumor necrosis factor (anti-TNF) agents. RESULTS: We assessed 25 patients (21 female; 47 affected eyes) with a mean +/- SD age of 18.5 +/- 8.3 years. Uveitis was bilateral in 22 patients. Cystoid macular edema was present in 9 patients. Ocular sequelae found at initiation of TCZ included cataracts (n = 13), glaucoma (n = 7), synechiae (n = 10), band keratopathy (n = 12), maculopathy (n = 9), and amblyopia (n = 5). Before TCZ, patients had received corticosteroids, conventional immunosuppressive drugs, and biologic agents (median 2 [range 1-5]), including adalimumab (n = 24), etanercept (n = 8), infliximab (n = 7), abatacept (n = 6), rituximab (n = 2), anakinra (n = 1), and golimumab (n = 1). Patients received 8 mg/kg TCZ intravenously every 4 weeks in most cases. TCZ yielded rapid and maintained improvement in all ocular parameters. After 6 months of therapy, 79.2% of patients showed improvement in anterior chamber cell numbers, and 88.2% showed improvement after 1 year. Central macular thickness measured by optical coherence tomography in patients with cystoid macular edema decreased from a mean +/- SD of 401.7 +/- 86.8 MUm to 259.1 +/- 39.5 MUm after 6 months of TCZ (P = 0.012). The best-corrected visual acuity increased from 0.56 +/- 0.35 to 0.64 +/- 0.32 (P < 0.01). After a median follow-up of 12 months, visual improvement persisted, and complete remission of uveitis was observed in 19 of 25 patients. Significant reduction in the prednisone dosage was also achieved. The main adverse effects were severe autoimmune thrombocytopenia in 1 patient, pneumonia and then autoimmune anemia and thrombocytopenia in 1 patient, and viral conjunctivitis and bullous impetigo in 1 patient. CONCLUSION: TCZ appears to be a useful therapy for severe refractory JIA-associated uveitis. PMID- 27696759 TI - High cholesterol dietary intake during pregnancy is associated with large for gestational age in a sample of low-income women of Rio de Janeiro, Brazil. AB - The association between the quality of maternal dietary fat intake during pregnancy and the infant's birthweight (BW) remains controversial. Our goal was to investigate the association between maternal dietary fat intake during pregnancy and the rate of large for gestational age (LGA) newborns. This study employed a cross-sectional analysis of 297 pairs of mothers/children attending a public maternity at Rio de Janeiro, Brazil. BW for gestational age according to the Intergrowth 21st was defined as follows: adequate for gestational age (AGA <= 90th percentile) and LGA (>90th percentile). The statistical analysis was a Poisson regression with robust estimations of the standard errors. Maternal dietary fat intake variables comprised lipids (% total energy); saturated (mg/1000 kcal), monounsaturated (mg/1000 kcal) and polyunsaturated (mg/1000 kcal) fats; and cholesterol (mg/1000 kcal), all of which were obtained with a Food Frequency Questionnaire. The mean BW was 3338 g (SD = 446.9), and the rate of LGA newborns was 13.1%. The mean maternal total energy intake was 2880 kcal (SD = 1074), cholesterol was 154.3 mg/1000 kcal (SD = 68.1) and monounsaturated fat was 6.9 mg/1000 kcal (SD = 2). Mothers of LGA newborns reported higher cholesterol dietary intake (195.8 vs. 148 mg/1000 kcal; P < 0.001), pre-pregnancy body mass index (25.1 vs. 23.5 kg/m2 ; P = 0.026) when compared with mothers of AGA newborns. Women with cholesterol intake within the fourth quartile were 2.48 (95% confidence interval: 1.31-4.66) times more likely to have an LGA infant compared with those in the 1-3 quartiles. Dietary intake of cholesterol during pregnancy influences LGA even after adjusting for other confounders. PMID- 27696758 TI - Gastrointestinal follicular lymphoma: using primary site as a predictor of survival. AB - Gastrointestinal follicular lymphoma (GI-FL) is a rare extranodal variant of follicular lymphoma (FL) that has been increasingly reported in the literature. An especially indolent course is linked to the disease after a lack of observed patient death in past studies. However, overall survival (OS) and associated prognostic factors remain unclear. A large population-based database was utilized to identify demographic and clinicopathologic characteristics of GI-FL, along with survival differences among primary sites. The Surveillance, Epidemiology, and End Results Registry was used to identify GI-FL cases between the years of 1973 and 2012. Kaplan-Meier curves compared OS differences and Cox proportional hazard models analyzed prognostic factors. Final analysis included 1109 cases. Small intestinal cases, which included those with single-site and multi-segment involvement, were most common (63.6%) followed by gastric (18.2%) and colorectal cases (18.2%). Small intestinal GI-FL presented more frequently with grade I histology, and less often with grade III histology (P < 0.001 and P < 0.001, respectively). Small intestinal cases had better outcomes (5-year OS = 80.9%, P < 0.001) compared to cases involving the stomach (5-year OS = 52.7%) and colorectum (5-year OS = 71.5%). On multivariate analysis for predictors of mortality, small intestinal involvement predicted for better survival; hazard ratio (HR) 0.66 (95% CI: 0.51-0.85). Advanced age (>=66), grade (grade III), and stage (Ann Arbor Stage III/IV) predicted for mortality with HR 5.46 (95% CI: 3.80-7.84), 1.42 (95% CI: 1.10-1.83), 1.57 (95% CI: 1.15-2.16), respectively. GI-FL has poorer outcomes than previously suggested. Small intestinal involvement has a better prognosis. A possible biological basis for this will require further investigations in the future. PMID- 27696760 TI - Integrating family work into the treatment of young people with severe and complex depression: a developmentally focused model. AB - AIM: Although models of family intervention are clearly articulated in the child and early adolescent literature, there is less clarity regarding family intervention approaches in later adolescence and emerging adulthood. METHODS: This study provides the rationale and intervention framework for a developmentally sensitive model of time-limited family work in the outpatient treatment of complex youth depression (15-25 years). RESULTS: Derived from current practice in the Youth Mood Clinic (YMC) at Orygen Youth Health, Melbourne, a stepped model of family intervention is discussed. YMC aims to provide comprehensive orientation, assessment and education to all families. For some, a family-based intervention, delivered either by the treating team or through the integration of a specialist family worker, offers an important adjunct in supporting the recovery of the young person. Developmental phases and challenges experienced by the young person with respect to family/caregiver involvement are discussed in the context of two case studies. CONCLUSIONS: A developmentally sensitive model is presented with particular attention to the developmental needs and preferences of young people. Formal evaluation of this model is required. Evaluation perspectives should include young people, caregivers, the broader family system (i.e. siblings) and the treating team (i.e. case manager, doctor and family worker) incorporating outcome measurement. Such work determines how best to apply a time-limited family-based intervention approach in strengthening family/caregiver relationships as part of the young person's recovery from severe and complex depression.

PMID- 27696762 TI - Effect of Disease Activity, Glucocorticoid Exposure, and Rituximab on Body Composition During Induction Treatment of Antineutrophil Cytoplasmic Antibody Associated Vasculitis. AB - OBJECTIVE: We investigated the relationships between glucocorticoid use, disease activity, and changes in body mass index (BMI) in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV). METHODS: We analyzed AAV patients enrolled in the Rituximab in AAV trial. Glucocorticoid use, BMI, and disease activity were measured regularly during the trial period. We performed mixed-effects regressions to examine the associations of time-dependent cumulative average glucocorticoid use and disease activity with changes in BMI over time, while adjusting for potential confounders. RESULTS: The mean +/- SD baseline BMI of the 197 patients enrolled was 28.8 +/- 6.3 kg/m2 . Patients with newly diagnosed AAV tended to have a lower mean +/- SD BMI than those with relapsing disease (28.0 +/- 5.7 kg/m2 versus 29.6 +/- 6.8 kg/m2 ) and higher disease activity (mean +/- SD Birmingham Vasculitis Activity Score for Wegener's Granulomatosis 8.7 +/- 3.3 versus 7.4 +/- 2.7). The most significant change in BMI occurred during the first 6 months of the trial (mean +/- SD increase of 1.1 +/- 2.2 kg/m2 ; P < 0.0001). Disease activity improvement, glucocorticoid exposure, and randomization to rituximab were each independently associated with an increase in BMI (P < 0.001 for all analyses). CONCLUSION: Our findings suggest that changes in BMI, as well as glucocorticoid exposure, are independently associated with improvements in disease activity in AAV. Rituximab may also have effects on BMI independent of its impact on disease activity. PMID- 27696763 TI - Longitudinal Changes in Magnetic Resonance Imaging-Based Measures of Femorotibial Cartilage Thickness as a Function of Alignment and Obesity: Data From the Osteoarthritis Initiative. AB - OBJECTIVE: To investigate the interaction between malalignment and body mass index (BMI) on cartilage thickness change in patients with knee osteoarthritis (OA). METHODS: Femorotibial cartilage thickness was measured from baseline to 2 years in 558 knees with radiographic OA. Cartilage thickness was determined in the central weight-bearing medial femorotibial cartilage (cMFTC) and lateral (cLFTC) compartments. Femorotibial angle (FTA) was stratified into neutral, minor, and definite malalignment. BMI was stratified using World Health Organization classifications for normal, overweight, and obese. Multivariable linear regression models were used to investigate the interaction between alignment and BMI, adjusting for age, sex, and disease severity. RESULTS: There was no significant interaction for continuous measures of alignment and BMI (P = 0.301 for cMFTC and P = 0.852 for cLFTC). Using BMI tertiles, the association between alignment and medial or lateral cartilage thickness loss was not moderated by BMI, despite a significant association of malalignment with greater cartilage thickness loss (P <= 0.005). Using FTA tertiles, the association between BMI and medial cartilage thickness loss was approximately 3 times greater in knees with definite malalignment (P = 0.149) and approximately 5 times greater in knees with minor malalignment (P = 0.006). Specifically, knees with minor varus significantly modified this relationship (P = 0.021). CONCLUSION: Malalignment was significantly associated with cartilage thickness loss per degree increase in malalignment, but was not moderated by BMI. BMI was significantly associated with greater rates of medial cartilage thickness loss per unit increase in BMI but only in knees with minor varus malalignment. These findings have implications for better understanding patient subgroups and intervention strategies targeting risk factors for knee OA. PMID- 27696764 TI - Effects of leukotriene D4 and histamine nasal challenge on airway responsiveness and inflammation in persistent allergic rhinitis patients. AB - BACKGROUND: Both histamine and leukotrienes are implicated in the pathogenesis of allergic rhinitis (AR), although the pattern and severity of the nasal response to these two potent inflammatory mediators may differ, which has not been adequately studied in patients with persistent AR. OBJECTIVE: We sought to compare the differential effects of nasal challenge with leukotriene D4 (LTD4 ) and histamine on the airway response and inflammation in patients with AR. METHODS: An open-label, crossover study was performed in 25 persistent AR patients (AR group) and 16 healthy subjects (control group). Participants randomly underwent histamine and LTD4 nasal provocation within a two-week interval. Nasal symptoms according to a visual analogue scale (VAS), fractional exhaled nitric oxide (FENO), nasal lavage, induced sputum, and spirometry were evaluated before and after nasal challenge. RESULTS: Nasal airway resistance (NAR) increased significantly after both LTD4 and histamine nasal challenge in AR patients (P < .05). The potency of LTD4 was 142-fold higher than that of histamine in increasing NAR (P < .001). The nasal symptom score induced by histamine challenge was significantly higher than that triggered by LTD4 (3.42 +/ 0.83 vs. 1.16 +/- 0.94, P < .05) in the AR group. LTD4 and histamine nasal challenge led to a significant increase in neutrophils in the nasal lavage and induced sputum (P < .05) in AR patients. There were no significant differences in the changes of eosinophils before and after LTD4 and histamine nasal challenges in nasal lavage and induced sputum. No significant changes in NAR, the induced symptom score, or inflammatory cells in the nasal lavage and sputum were found in the control group. CONCLUSIONS: LTD4 and histamine nasal challenge caused different patterns and severities of nasal symptoms, which correlated with symptoms (TSS) that affect patient's daily life. LTD4 was far more potent than histamine at increasing the NAR, while histamine nasal challenge induced more sneezing and nasal discharge. These results may guide the prescription of anti histamine or anti-leukotriene agents for treating different AR phenotypes. PMID- 27696765 TI - Lung function, respiratory symptoms and venous thromboembolism risk: the Atherosclerosis Risk in Communities Study. AB - : Essentials The association of lung function with venous thromboembolism (VTE) is unclear. Chronic obstructive pulmonary disease (COPD) patterns were associated with a higher risk of VTE. Symptoms were also associated with a higher risk of VTE, but a restrictive pattern was not. COPD may increase the risk of VTE and respiratory symptoms may be a novel risk marker for VTE. SUMMARY: Background The evidence for the association between chronic obstructive pulmonary disease (COPD) and venous thromboembolism (VTE) is limited. There is no study investigating the association between restrictive lung disease (RLD) and respiratory symptoms with VTE. Objectives To investigate prospectively the association of lung function and respiratory symptoms with VTE. Patients/Methods In 1987-1989, we assessed lung function by using spirometry, and obtained information on respiratory symptoms (cough, phlegm, and dyspnea) in 14 654 participants aged 45-64 years, without a history of VTE or anticoagulant use, and followed them through 2011. Participants were classified into four mutually exclusive groups: 'COPD' (forced expiratory volume in 1 s [FEV1 ]/forced vital capacity [FVC] below the lower limit of normal [LLN]), 'RLD' (FEV1 /FVC >= LLN and FVC < LLN), 'respiratory symptoms with normal spirometic results' (without RLD or COPD), and 'normal' (without respiratory symptoms, RLD, or COPD). Results We documented 639 VTEs (238 unprovoked and 401 provoked VTEs). After adjustment for VTE risk factors, VTE risk was increased for individuals with either respiratory symptoms with normal spirometric results (hazard ratio [HR] 1.40, 95% confidence interval [CI] 1.12-1.73) or COPD (HR 1.33, 95% CI 1.07-1.67) but not for those with RLD (HR 1.15, 95% CI 0.82-1.60). These elevated risks of VTE were derived from both unprovoked and provoked VTE. Moreover, FEV1 and FEV1 /FVC showed dose-response relationships with VTE. COPD was more strongly associated with pulmonary embolism than with deep vein thrombosis. Conclusions Obstructive spirometric patterns were associated with an increased risk of VTE, suggesting that COPD may increase the risk of VTE. Respiratory symptoms may represent a novel risk marker for VTE. PMID- 27696766 TI - Utilization of Care Outside the Veterans Affairs Health Care System by US Veterans With Rheumatoid Arthritis. AB - OBJECTIVE: Many veterans enrolled in Veterans Affairs (VA) health care systems also receive care through other health care systems. Both VA and non-VA health care use must therefore be considered when conducting research in this population. This study characterized dual-care utilization in veterans with rheumatoid arthritis (RA) and explored associations with RA disease activity. METHODS: Through a questionnaire mailed to RA patients at 3 VA sites, veterans reported medical services by non-VA primary care and subspecialty providers, comorbidities, non-VA medications, and hospitalizations. Disease Activity Score in 28 joints (DAS28) and Multidimensional Health Assessment Questionnaire (MD HAQ) scores were recorded during VA clinic visits, and respondent groups were compared. RESULTS: Of the 510 participants surveyed, 318 (62%) responded. Respondents were older (ages 69 versus 66 years; P = 0.006), more likely nonsmokers (80% versus 67%; P = 0.001), and had lower disease activity (DAS28 3.3 versus 3.8; P < 0.001, MD-HAQ 0.8 versus 0.9; P = 0.01) than nonrespondents (n = 192 [38%]). The respondents with a non-VA provider (n = 130 [41%]) were older (71 versus 68 years; P = 0.001) and had more education (14 versus 13 years; P = 0.021) than nondual-care users. Only 6% of respondents reported having a non-VA rheumatologist, with 2% receiving a non-VA prescribed biologic agent or disease modifying antirheumatic drug. CONCLUSION: In this study, VA beneficiaries with RA had lower dual-care utilization than previously reported for the general VA population, with few patients receiving dual rheumatology care or non-VA RA medications. This survey suggests that most US veterans with RA who access VA care use the VA as their primary source of arthritis care. PMID- 27696767 TI - Clinical Significance of Medial Versus Lateral Compartment Patellofemoral Osteoarthritis: Cross-Sectional Analyses in an Adult Population With Knee Pain. AB - OBJECTIVE: To determine the comparative prevalence, associations with selected patient characteristics, and clinical outcomes of medial and lateral compartment patellofemoral (PF) joint osteoarthritis (OA). METHODS: Information was collected by questionnaires, clinical assessment, and radiographs from 745 eligible community-dwelling symptomatic adults age >=50 years. PF joint space narrowing (JSN) and osteophytes were scored from skyline radiographs using the Osteoarthritis Research Society International atlas. Multilevel models were used to assess associations of compartmental PF joint OA with age, sex, body mass index (BMI) and varus-valgus malalignment, while median regression was used to examine associations with clinical outcomes (current pain intensity on a numeric rating scale [0-10] and the function subscale of the Western Ontario and McMaster Universities Osteoarthritis Index [0-68]). RESULTS: Isolated lateral PF joint OA was more common than isolated medial PF joint OA, particularly at higher severity thresholds. Irrespective of severity threshold, age (>=2 odds ratio [OR] 1.19 [95% confidence interval (95% CI) 1.12, 1.26]), BMI (>=2 OR 1.15 [95% CI 1.07, 1.24]), and valgus malalignment (>=2 OR 2.58 [95% CI 1.09, 6.07]) were associated with increased odds of isolated lateral JSN, but isolated medial JSN was only associated with age (>=2 OR 1.20 [95% CI 1.14, 1.27]). The pattern of association was less clear for PF joint osteophytes. Isolated lateral PF joint OA, defined by JSN or osteophytes, was associated with higher pain scores than isolated medial PF joint OA, but these differences were modest and were not significant. A similar pattern of association was seen for functional limitation but only when PF joint OA was defined by JSN. CONCLUSION: Isolated lateral PF joint OA is more common than isolated medial PF joint OA, and it is more consistently associated with established OA risk factors. It is also associated with higher, but clinically nonsignificant, pain and function scores than isolated medial PF joint OA, particularly when PF joint OA is defined using JSN. PMID- 27696768 TI - CD8+ T Cells Contribute to the Development of Coronary Arteritis in the Lactobacillus casei Cell Wall Extract-Induced Murine Model of Kawasaki Disease. AB - OBJECTIVE: Kawasaki disease (KD) is the leading cause of acquired heart disease among children in developed countries. Coronary lesions in KD in humans are characterized by an increased presence of infiltrating CD3+ T cells; however, the specific contributions of the different T cell subpopulations in coronary arteritis development remain unknown. Therefore, we sought to investigate the function of CD4+ and CD8+ T cells, Treg cells, and natural killer (NK) T cells in the pathogenesis of KD. METHODS: We addressed the function of T cell subsets in KD development by using a well-established murine model of Lactobacillus casei cell wall extract (LCWE)-induced KD vasculitis. We determined which T cell subsets were required for development of KD vasculitis by using several knockout murine strains and depleting monoclonal antibodies. RESULTS: LCWE-injected mice developed coronary lesions characterized by the presence of inflammatory cell infiltrates. Frequently, this chronic inflammation resulted in complete occlusion of the coronary arteries due to luminal myofibroblast proliferation (LMP) as well as the development of coronary arteritis and aortitis. We found that CD8+ T cells, but not CD4+ T cells, NK T cells, or Treg cells, were required for development of KD vasculitis. CONCLUSION: The LCWE-induced murine model of KD vasculitis mimics many histologic features of the disease in humans, such as the presence of CD8+ T cells and LMP in coronary artery lesions as well as epicardial coronary arteritis. Moreover, CD8+ T cells functionally contribute to the development of KD vasculitis in this murine model. Therapeutic strategies targeting infiltrating CD8+ T cells might be useful in the management of KD in humans.

In the biodistribution study, high radioactivity accumulation of [18 F]EAEF were found in uterus (5.73 +/- 1.83% ID/g) and ovary (4.05 +/- 0.73% ID/g) at 2 hr postinjection (p.i.), which have high progesterone receptor expression after treated with estradiol, while the muscle background has very low uptake (0.50 +/- 0.17% ID/g). For positron emission tomography imaging, [18 F]EAEF showed high uptake in progesterone receptor-positive MCF-7 tumor (3.15 +/- 0.07% ID/g at 2 hr p.i.) with good tumor to muscle ratio (2.90), and obvious lower tumor uptakes were observed in MCF-7 with EAEF blocking (1.84 +/- 0.05% ID/g at 2 hr p.i.) or in progesterone receptor negative MDA-MB-231 tumor (1.80 +/- 0.03% ID/g at 2 hr p.i.). Based on the good stability and specificity of [18 F]EAEF, it may be a good candidate for imaging progesterone receptor and worth further investigation.

This study aimed to assess the prevalence of use of these medications in older adults and evaluate predictors of their use. METHODS: Cross sectional study using data from the National Social Life, Health, and Aging Project (NSHAP), a nationally representative sample of community-dwelling, U.S. adults 57 to 85 years (n = 2976) collected in 2005-2006. We determined prevalence of medication use and used logistic regression to evaluate sociodemographic and health factors associated with their use. RESULTS: Overall prevalence of allergy medication usage was 8.4% (most commonly antihistamines), and prevalence of asthma medication usage was 8.0% (most commonly bronchodilators). Allergy medication use was significantly associated with history of asthma (odds ratio [OR] 2.37; 95% confidence interval [CI], 1.52 to 3.69), chronic obstructive pulmonary disease (COPD) (OR 2.35; 95% CI, 1.58 to 3.51), or nasal surgery (OR 1.97; 95% CI, 1.00 to 3.86). Older age was associated with decreased allergy medication use (per decade, OR 0.80; 95% CI, 0.66 to 0.98). Although increased education was associated with increased overall allergy medication use, it was associated with decreased use of allergy medications generally contraindicated in the elderly. In contrast, the only significant predictors of asthma medication use were history of asthma (OR 19.66; 95% CI, 3.18 to 121.70) or COPD (OR 4.25; 95% CI, 0.88 to 20.44). CONCLUSION: Allergy and asthma medication use is prevalent among older adults and driven mostly by history of asthma or COPD. Additional sociodemographic factors predict allergy (but not asthma) medication use. Further studies are needed to evaluate efficacy of these drugs in the elderly. PMID- 27696774 TI - Detection of erythropoietin misuse by the Athlete Biological Passport combined with reticulocyte percentage. AB - The sensitivity of the adaptive model of the Athlete Biological Passport (ABP) and reticulocyte percentage (ret%) in detection of recombinant human erythropoietin (rHuEPO) misuse was evaluated using both a long-term normal dose and a brief high dose treatment regime. Sixteen subjects received either 65 IU rHuEPO * kg-1 every second day for two weeks (normal-dose), 390 IU rHuEPO * kg-1 on three consecutive days (high-dose), or frequent placebo treatment for 13 days in a randomized, placebo-controlled, double-blind crossover design. Blood variables were measured 4, 11, and 25 days following treatment initiation. The ABP based on haemoglobin concentration ([Hb]) and OFF-hr score ([Hb] - 60 * ?ret%) yielded atypical profiles following both normal-dose and high-dose treatment (0 %, 31 %, 13 % vs. 21 %, 33 %, 20 % at days 4, 11, and 25 after normal and high dose, respectively). Including ret% as a stand-alone marker for atypical blood profiles increased (P < 0.05) the sensitivity of the adaptive model at day 11 to 63 % and 67 % for normal-dose and high-dose rHuEPO administration, respectively. In conclusion, ~30 % of subjects injecting a normal dose rHuEPO for two weeks or a high-dose rHuEPO for three days will present an atypical ABP profile. Including ret% as a stand-alone parameter improves the sensitivity two-fold. Copyright (c) 2015 John Wiley & Sons, Ltd. PMID- 27696773 TI - Effectiveness of Ultrasound-Guided Compared to Blind Steroid Injections in the Treatment of Carpal Tunnel Syndrome. AB - OBJECTIVE: To compare the effectiveness of ultrasound-guided injections to blind injections in the treatment of carpal tunnel syndrome (CTS) in a large community based cohort. METHODS: This study evaluated residents of Olmsted County, Minnesota, treated with a corticosteroid injection for CTS between 2001 and 2010. The proportion of patients receiving retreatment and the duration of retreatment free survival between blind and ultrasound-guided injections were compared. Propensity score matching was used to control for confounding by indication. RESULTS: In the matched data set consisting of 234 (of 600) hands treated with a blind injection and 87 (of 89) ultrasound-guided injection cases, ultrasound guidance was associated with a reduced hazard of retreatment (hazard ratio 0.59 [95% confidence interval (95% CI) 0.37-0.93]). In addition, ultrasound guidance was associated with 55% reduced odds of retreatment within 1 year compared to blind injections (adjusted odds ratio 0.45 [95% CI 0.24-0.83]). CONCLUSION: This study indicates that ultrasound-guided injections are more effective in comparison to blind injections in the treatment of CTS. PMID- 27696776 TI - 5alpha-Dihydrotestosterone negatively regulates cell proliferation of the periurethral ventral mesenchyme during urethral tube formation in the murine male genital tubercle. AB - Androgen is an essential factor involved in masculinization of external genitalia. Failure of the exposure to 5alpha-dihydrotestosterone (DHT) causes a hypoplastic penile size and urethral abnormality. The main pathology of hypospadias is defective urethral closure on the ventral side of the penis. Hormone-dependent genes are suggested as the causative factors. However, the detailed mechanisms of DHT functions on urethral tube formation remain unknown. Androgen is both a positive and negative regulator of cell proliferation. The roles of locally converted DHT in cell proliferation at the periurethral mesenchyme have not been elucidated. We revealed the expression pattern of 5alpha reductase type 2 mRNA (Srd5a2) and local DHT distribution by direct measurement in this study. We also analyzed periurethral mesenchymal cell proliferation status using systematic three-dimensional (3D) reconstruction analyses. A prominent Srd5a2 expression and localized DHT distribution on the ventral side of the genital tubercle were detected. Cell proliferation was reduced in this mesenchymal region during urethral formation. The current results suggest the presence of the possible negative regulation of cell proliferation by DHT. Moreover, cell proliferation related to urethral tube formation was revealed to be DHT dose dependent. These data are expected to contribute to the understanding of the mode of regulation of cell proliferation related to urethral tube formation by DHT. These findings may also offer insight into the understanding of human hypospadias and related hormone-dependent factors. PMID- 27696775 TI - Laccase: a multi-purpose biocatalyst at the forefront of biotechnology. AB - Laccases are multicopper containing enzymes capable of performing one electron oxidation of a broad range of substrates. Using molecular oxygen as the final electron acceptor, they release only water as a by-product, and as such, laccases are eco-friendly, versatile biocatalysts that have generated an enormous biotechnological interest. Indeed, this group of enzymes has been used in different industrial fields for very diverse purposes, from food additive and beverage processing to biomedical diagnosis, and as cross-linking agents for furniture construction or in the production of biofuels. Laccases have also been studied intensely in nanobiotechnology for the development of implantable biosensors and biofuel cells. Moreover, their capacity to transform complex xenobiotics makes them useful biocatalysts in enzymatic bioremediation. This review summarizes the most significant recent advances in the use of laccases and their future perspectives in biotechnology. PMID- 27696777 TI - Association of Anti-Citrullinated Peptide Antibodies With Coronary Artery Calcification in Rheumatoid Arthritis. AB - OBJECTIVE: Citrullinated proteins have been found within atherosclerotic plaque. However, studies evaluating the association between anti-citrullinated protein antibodies (ACPAs) and imaging measures of atherosclerosis in patients with rheumatoid arthritis (RA) have been limited to seroreactive citrullinated fibrinogen or citrullinated vimentin and have rendered contradictory results. Therefore, our objective was to evaluate this association using an extended panel of ACPAs in a larger sample of RA patients without clinical cardiovascular disease (CVD). METHODS: ACPAs were identified using a custom Bio-Plex bead assay in 270 patients from 2 independent RA cohorts without clinical CVD, with the first one consisting of 195 patients and the other of 75 patients. Coronary artery calcium (CAC) was assessed by computed tomography as a measure of coronary artery disease. RESULTS: High levels of anti-citrullinated histone H2B antibodies were strongly associated with higher CAC scores, compared with lower antibody levels (P = 0.001); this remained significant after adjustment for traditional CV and RA-specific risk factors (P = 0.03). No association between levels of ACPAs and CAC progression at 3 years was seen (P = 0.09); however, the number of progressors was small (n = 92). CONCLUSION: Higher levels of ACPAs targeting Cit histone H2B were associated with higher CAC scores when compared to lower antibody levels, suggesting a potential role for histone citrullination seroreactivity in atherosclerosis.

PMID- 27696778 TI - Little Evidence for Usefulness of Biomarkers for Predicting Successful Dose Reduction or Discontinuation of a Biologic Agent in Rheumatoid Arthritis: A Systematic Review. AB - OBJECTIVE: To systematically review studies addressing prediction of successful dose reduction or discontinuation of a biologic agent in rheumatoid arthritis (RA). METHODS: PubMed, Embase, and Cochrane Library databases were searched for studies that examined the predictive value of biomarkers for successful dose reduction or discontinuation of a biologic agent in RA. Two reviewers independently selected studies, and extracted data and assessed the risk of bias. A biomarker was classified as a "potential predictor" if the univariate association was either strong (odds ratio or hazard ratio >2.0 or <0.5) or statistically significant. For biomarkers that were studied multiple times, qualitative best-evidence synthesis was performed separately for the prediction of successful dose reduction and discontinuation. Biomarkers that were defined in >=75% of the studies as potential predictors were regarded as "predictor" for the purposes of our study. RESULTS: Of 3,029 nonduplicate articles initially searched, 16 articles regarding 15 cohorts were included in the present study. Overall, 17 biomarkers were studied multiple times for the prediction of successful dose reduction, and 33 for the prediction of successful discontinuation of a biologic agent. Three predictors were identified: higher adalimumab trough level for successful dose reduction and lower Sharp/van der Heijde erosion score and shorter symptom duration at the start of a biologic agent for successful discontinuation. CONCLUSION: The predictive value of a wide variety of biomarkers for successful dose reduction or discontinuation of biologic treatment in RA has been investigated. We identified only 3 biomarkers as predictors, in just 2 studies. The strength of the evidence is limited by the low quality of the included studies and the likelihood of reporting bias and multiple testing. PMID- 27696779 TI - Standards of Comparison and Discordance in Rheumatoid Arthritis Global Assessments Between Patients and Clinicians. AB - OBJECTIVE: Patient-physician discordance in health status ratings may arise because patients use temporal comparisons (comparing their current status with their previous status), while clinicians use social comparisons (comparing this patient's status to that of other patients, or to the full range of disease severity possible) to guide their assessments. We compared discordance between patients with rheumatoid arthritis (RA) and clinicians, using either the conventional patient global assessment (PGA) or a rating scale with 5 anchors describing different health states. We hypothesized that discordance would be smaller with the rating scale because clinicians likely used similar social comparisons when making global assessments. METHODS: We prospectively studied 206 patients with active RA and assessed the PGA (range 0-100), rating scale (range 0 100), and evaluator global assessment (EGA; range 0-100) on each of 2 visits (total visits = 401). We compared the PGA/EGA discordance and the rating scale/EGA discordance at each visit. RESULTS: The mean +/- SD PGA/EGA discordance was 8.5 +/- 22.4, and the mean +/- SD rating scale/EGA discordance was 2.3 +/- 24.0. The intraclass correlation, measuring agreement, was higher between the rating scale and EGA than between the PGA and EGA (0.39 versus 0.31). Agreement was larger at low levels of RA activity on both pairs of measures. CONCLUSION: Discordance between patients' global assessments and evaluators' global assessments was smaller when patients used a social standard of comparison than when they marked the PGA, suggesting that differences in standards of comparison contribute to patient-clinician discordance when the PGA is used. PMID- 27696781 TI - Supercritical fluid chromatography for lipid analysis in foodstuffs. AB - The task of lipid analysis has always challenged separation scientists, and new techniques in chromatography were often developed for the separation of lipids; however, no single technique or methodology is yet capable of affording a comprehensive screening of all lipid species and classes. This review acquaints the role of supercritical fluid chromatography within the field of lipid analysis, from the early developed capillary separations based on pure CO2 , to the most recent techniques employing packed columns under subcritical conditions, including the niche multidimensional techniques using supercritical fluids in at least one of the separation dimensions. A short history of supercritical fluid chromatography will be introduced first, from its early popularity in the late 1980s, to the sudden fall and oblivion until the last decade, experiencing a regain of interest within the chromatographic community. Afterwards, the subject of lipid nomenclature and classification will be briefly dealt with, before discussing the main applications of supercritical fluid chromatography for food analysis, according to the specific class of lipids.

PMID- 27696782 TI - Human Endogenous Retroviral Genetic Element With Immunosuppressive Activity in Both Human Autoimmune Diseases and Experimental Arthritis. AB - OBJECTIVE: Human endogenous retroviruses (HERVs) are remnants of past retroviral infections in the human genome and have been implicated in different aspects of human biology. The aim of this study was to identify HERVs that are associated with the pathogenesis of rheumatic diseases such as systemic lupus erythematosus (SLE). METHODS: The study subjects included 45 female patients with SLE and 50 healthy controls matched for geographic area, age, and sex. Real-time reverse transcription-polymerase chain reaction analysis was used to examine the transcription levels of 11 genes with coding capacity for complete envelope (Env) protein in these individuals. In this way, 1 HERV locus was identified as a potential modulator of autoimmunity. The env gene encoded by this HERV locus was cloned and examined for the ability to express a functional protein with immunosuppressive potential. RESULTS: Expression of the env59 gene was negatively correlated with pathogenetic factors of human autoimmune rheumatic diseases, including such factors as the levels of interleukin-6 (IL-6) and Toll-like receptor 7. This gene was capable of encoding a fully functional Env glycoprotein that was found to contain a domain, the immunosuppressive (ISU) domain, that, when evaluated ex vivo in patients with SLE and those with rheumatoid arthritis as well as in animal models, showed strong antiinflammatory activity, including the ability to lower IL-6 levels. CONCLUSION: The env59 gene has been adapted by the immune system as a control mechanism in autoimmunity. The peptides derived from the ISU domain contained in the Env59 protein may be useful as potentially new biologic treatments in rheumatic diseases such as SLE. PMID- 27696784 TI - Relationship Between Neuromyelitis Optica Spectrum Disorder and Sjogren's Syndrome: Central Nervous System Extraglandular Disease or Unrelated, Co Occurring Autoimmunity? AB - OBJECTIVE: Sjogren's syndrome (SS) patients may be affected by the neuromyelitis optica spectrum disorder (NMOSD), a severe demyelinating syndrome associated with anti-aquaporin 4 antibodies (anti-AQP-4 antibodies). The relationship between SS and NMOSD has been a sustained focus of investigation. Among SS patients, anti AQP-4 antibodies have been detected exclusively in those with NMOSD. It has therefore been speculated that NMOSD is not a neurologic complication of SS. However, such studies evaluated small numbers of SS patients, often mixed with other inflammatory disorders. METHODS: We compared frequencies of anti-AQP-4 and SS-associated antibodies in 109 SS patients, including 11 with NMOSD, 8 with non NMOSD demyelinating syndromes, and 90 without demyelinating syndromes. RESULTS: When assessed using a fluorescence-activated cell sorting (FACS) assay, anti-AQP 4 antibodies were seen exclusively in those SS patients with NMOSD (72.7%), but not in SS patients without NMOSD (P < 0.01). In contrast, anti-Ro 52, anti-Ro 60, and other autoantibodies were not more prevalent in SS patients with NMOSD versus those without. Anti-AQP-4 antibodies were detected more frequently among NMOSD patients by FACS assay than with a commercial immunohistochemical assay (72.7% versus 54.5%), despite assessment after a more prolonged period of immunosuppressive therapy (median 38 months versus 5 months; P < 0.01). CONCLUSION: The syndrome-specificity of anti-AQP-4 antibodies, along with an otherwise similar antibody profile in SS NMOSD patients, indicates that NMOSD is not a direct central nervous system manifestation of SS. Anti-AQP-4 antibodies can persist and be refractory to prolonged immunosuppressive therapy.

PMID- 27696786 TI - Secukinumab for Long-Term Treatment of Psoriatic Arthritis: A Two-Year Followup From a Phase III, Randomized, Double-Blind Placebo-Controlled Study. AB - OBJECTIVE: To assess the 2-year efficacy and safety of the interleukin-17A inhibitor, secukinumab, in active psoriatic arthritis (PsA). METHODS: In the FUTURE-1 study, 606 patients with active PsA were randomized to secukinumab 10 mg/kg intravenously at baseline, and at weeks 2 and 4, followed by 150 mg or 75 mg subcutaneously (SC) every 4 weeks from week 8, or matching placebo. Patients receiving placebo were re-randomized to secukinumab 150 mg or 75 mg SC from week 16 or week 24, depending upon clinical response. Treatment continued to week 104. Exploratory analysis of all primary and secondary end points, on an intent-to treat basis, continued to week 104. RESULTS: A total of 476 patients (78.5%) completed 104 weeks of treatment. Secukinumab showed sustained efficacy across multiple domains of PsA through week 104, including signs and symptoms, disease activity, quality of life, physical function, skin symptoms, dactylitis, and enthesitis. American College of Rheumatology criteria for 20% improvement response rates were 66.8% with secukinumab 150 mg and 58.6% with secukinumab 75 mg at week 104; Psoriasis Area and Severity Index criteria for 75% improvement response rates were 74.6% and 63.0%, respectively (multiple imputed data). At week 104, 84.3% of patients in the secukinumab 150 mg group and 83.8% in the secukinumab 75 mg group showed no radiographic disease progression (observed data). No new or unexpected safety signals were reported during 2 years of treatment. Immunogenicity to secukinumab was low. CONCLUSION: Secukinumab provided sustained improvements in PsA at 2 years, with very little radiographic progression. Treatment was well tolerated over the long term. PMID- 27696787 TI - A PEGylated bovine hemoglobin as a potent hemoglobin-based oxygen carrier. AB - Hemoglobin (Hb)-based oxygen carriers (HBOCs) have been used as blood substitutes in surgery medicine and oxygen therapeutics for ischemic stroke. As a potent HBOC, the PEGylated Hb has received much attention for its oxygen delivery and plasma expanding ability. Two PEGylated Hbs, Euro-Hb, and MP4 have been developed for clinical trials, using human adult hemoglobin (HbA) as the original substrate. However, HbA was obtained from outdated human blood and its quantity available from this source may not be sufficient for mass production of PEGylated HbA. In contrast, bovine Hb (bHb) has no quantity constraints for its ample resource. Thus, bHb is of potential to function as an alternative substrate to obtain a PEGylated bHb (bHb-PEG). bHb-PEG was prepared under the same reaction condition as HbA-PEG, using maleimide chemistry. The structural, functional, solution and physiological properties of bHb-PEG were determined and compared with those of HbA-PEG. bHb-PEG showed higher hydrodynamic volume, colloidal osmotic pressure, viscosity and P50 than HbA-PEG. The high P50 of bHb can partially compensate the PEGylation-induced perturbation in the R to T state transition of HbA. bHb-PEG was non-vasoactive and could efficiently recover the mean arterial pressure of mice suffering from hemorrhagic shock. Thus, bHb-PEG is expected to function as a potent HBOC for its high oxygen delivery and strong plasma expanding ability. (c) 2016 American Institute of Chemical Engineers Biotechnol.

AB - OBJECTIVE: Coronary artery disease (CAD) in the general population is characterized by an increased frequency of particular susceptibility single nucleotide polymorphisms (SNPs). Because the frequency of CAD is increased among patients with rheumatoid arthritis (RA), we sought to determine whether the frequency of these SNPs is increased in RA patients with CAD, hypothesizing that RA could enhance CAD risk by acting through established genetic pathways predisposing to CAD. METHODS: Coronary artery calcification (CAC) as detected by computed tomography was used as a measure of CAD in 561 patients with RA. One hundred SNPs associated with CAD in the general population were genotyped or imputed, and their relationship to CAC was established through multiple regression analysis for individual SNPs and a genetic risk score representing their cumulative effect. RESULTS: Ninety-one CAD-related SNPs were genotyped successfully; of these, 81 exhibited no association with CAC (Agatston units) or different CAC categorizations, either individually or collectively, in the genetic risk score. Only rs579459 (ABO) and rs17676451 (HAL) had a consistent positive association between genotype and CAC, with a significant increase in the frequency of the effect allele in both homozygous and heterozygous genotype distributions. Five were variably negatively associated. Furthermore, a positive association between the Disease Activity Score in 28 joints and CAC was observed, and after adjustment for traditional cardiovascular risk factors, it was not modified by correcting for the CAD-related SNP genetic risk score. CONCLUSION: The increased risk of CAC in patients with RA does not appear to operate primarily through established genetically regulated atherogenic mechanisms that are preponderant in the general population. PMID- 27696791 TI - Defining Low Disease Activity in Systemic Lupus Erythematosus. AB - OBJECTIVE: To define and identify a group of systemic lupus erythematosus patients with low disease activity (LDA) and to examine whether LDA is similar to patients in remission and different from a high disease activity group (HDA) in short-term outcomes. METHODS: The LDA group was defined as Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) <3, including only 1 clinical manifestation of rash, alopecia, mucosal ulcers, pleurisy, pericarditis, fever, thrombocytopenia, or leukopenia. The patients could be taking antimalarials. Remission was defined as no clinical manifestation from taking antimalarials alone, and the HDA group was defined as SLEDAI-2K >6. The time frame for inclusion in each group was at least 1 year. RESULTS: Of 620 patients with active disease who were seen between 1970 and 2015, 80 patients (12.9%) fulfilled the criteria for LDA, 191 (30.8%) for remission, and 349 (56.3%) for HDA. The LDA patients with and without positive serology results were similar at baseline and with prior disease characteristics. After 2 years of followup, the LDA and remission groups were similar in their adjusted mean SLEDAI-2K score, organ involvement, The Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) score, mortality, and therapies. After 2 and 4 years of followup, the HDA group had a higher adjusted mean SLEDAI-2K score, more major organ involvement, a higher SDI score, higher mortality, and more therapy compared to the combined LDA/remission groups. CONCLUSION: LDA and remission groups had similar short-term outcomes, and both had better outcomes and prognosis than the HDA group. LDA may be used as an outcome measure in therapeutic trials or in treat-to-target regimens. PMID- 27696790 TI - Disease Activity During Pregnancy and the First Year Postpartum in Women With Systemic Lupus Erythematosus. AB - OBJECTIVE: Disease activity measured by validated methods has been sparsely examined during and after pregnancy in women with systemic lupus erythematosus (SLE). The aim of this study was to describe the longitudinal course of disease activity during pregnancy and the first year postpartum using the Lupus Activity Index in Pregnancy (LAI-P). METHODS: RevNatus is a nationwide Norwegian prospective observational register including women diagnosed with inflammatory rheumatic diseases. LAI-P is a modified version of the LAI, with a good ability to assess disease activity in pregnant women with SLE. These indexes were used to assess disease activity at 6 visits (in trimesters 1, 2, and 3, and at 6 weeks, 6 months, and 12 months postpartum). The longitudinal course of disease activity was analyzed using an ordinal logistic mixed model. RESULTS: A total of 757 visits (145 pregnancies) in women with SLE were included in the analysis. More than half (51.6%) of the disease activity scores indicated remission, and only 6.3% indicated moderate disease activity. The model showed a statistically significant and clinically relevant change in disease activity over time, and a higher disease activity 6 and 12 months postpartum compared to the third trimester and 6 weeks postpartum. CONCLUSION: The majority of women had low or no disease activity at conception and during pregnancy, with higher disease activity at 6 and 12 months after delivery. This points to the importance of tight disease control not only before and during pregnancy but also in the first year postpartum. PMID- 27696792 TI - Immobilization of recombinant pectate lyase from Clostridium thermocellum ATCC 27405 on magnetic nanoparticles for bioscouring of cotton fabric. AB - Recombinant pectate lyase from family 1 polysaccharide lyase (PL1B) was immobilized on synthesized magnetic nanoparticles (MNPs) after 1-ethyl-3-(3 dimethylaminopropyl) carbodiimide hydrochloride activation. At 70 mg/mL MNPs 100% binding of 1 mg/mL PL1B was achieved. The immobilized PL1B-MNP displayed activity of 20.3 and 18.2 U/mg against polygalacturonic acid and citrus pectin, respectively, which was higher than the activity of free PL1B, on the same substrates of 17.8 and 16.2 U/mg. The immobilized PL1B-MNP showed 32 fold and 14 fold enhanced thermal stability at 80 degrees C and 90 degrees C, respectively as compared with free PL1B at same temperatures. At high temperature the immobilized PL1B-MNP retained its activity for a longer duration than free PL1B. The immobilized PL1B-MNP could be reused till five cycles and after that it retained 70% of initial activity. It could be easily recovered from the reaction mixture with the help of a magnet. Bioscouring of cotton fabric was carried out with immobilized PL1B-MNP which showed efficient removal of pectin from the fabric surface. The enhanced wettability of fabric resulted in the decrease of the water absorbing time period from 3 min taken by the free PL1B treated fabric to 15 s taken by the immobilized PL1B-MNP treated fabric. As per our knowledge this is the first attempt of bioscouring of coarse cotton fabric by pectinase immobilized on magnetic nanoparticles. (c) 2016 American Institute of Chemical Engineers Biotechnol.

AB - Natural bicyclic sesquiterpenes, beta-caryophyllene (BCP) and beta-caryophyllene oxide (BCPO), are present in a large number of plants worldwide. Both BCP and BCPO (BCP(O)) possess significant anticancer activities, affecting growth and proliferation of numerous cancer cells. Nevertheless, their antineoplastic effects have hardly been investigated in vivo. In addition, both compounds potentiate the classical drug efficacy by augmenting their concentrations inside the cells. The mechanisms underlying the anticancer activities of these sesquiterpenes are poorly described. BCP is a phytocannabinoid with strong affinity to cannabinoid receptor type 2 (CB2 ), but not cannabinoid receptor type 1 (CB1 ). In opposite, BCP oxidation derivative, BCPO, does not exhibit CB1/2 binding, thus the mechanism of its action is not related to endocannabinoid system (ECS) machinery. It is known that BCPO alters several key pathways for cancer development, such as mitogen-activated protein kinase (MAPK), PI3K/AKT/mTOR/S6K1 and STAT3 pathways. In addition, treatment with this compound reduces the expression of procancer genes/proteins, while increases the levels of those with proapoptotic properties. The selective activation of CB2 may be considered a novel strategy in pain treatment, devoid of psychoactive side effects associated with CB1 stimulation. Thus, BCP as selective CB2 activator may be taken into account as potential natural analgesic drug. Moreover, due to the fact that chronic pain is often an element of cancer disease, the double activity of BCP, anticancer and analgesic, as well as its beneficial influence on the efficacy of classical chemotherapeutics, is particularly valuable in oncology. This review is focused on anticancer and analgesic activities of BCP and BCPO, the mechanisms of their actions, and potential therapeutic utility. PMID- 27696793 TI - Internet Program for Physical Activity and Exercise Capacity in Children With Juvenile Idiopathic Arthritis: A Multicenter Randomized Controlled Trial. AB - OBJECTIVE: To determine the effects of Rheumates@Work, an internet-based program supplemented with 4 group sessions, aimed at improving physical activity, exercise capacity, health-related quality of life (HRQoL), and participation in children with juvenile idiopathic arthritis. METHODS: Patients were recruited from 3 pediatric rheumatology centers in The Netherlands for an observer-blinded, randomized controlled multicenter trial. Physical activity level, time spent in rest, light, and moderate-to-vigorous physical activity (MVPA) were recorded in a diary and with an accelerometer, before intervention, after intervention, and at followup after 3 and 12 months (intervention group only). Exercise capacity was assessed using the Bruce treadmill protocol, HRQoL was assessed with the Pediatric Quality of Life Inventory generic core scale, and participation in school and in physical education classes were assessed by questionnaire. RESULTS: The intervention group consisted of 28 children, and there were 21 children in the control group. MVPA, exercise capacity, and participating in school and physical education classes improved significantly in the intervention group. HRQoL improved in the control group. No significant differences were found between groups. The effect of Rheumates@Work on physical activity and exercise capacity lasted during the 12 months of followup. Improvements in physical activity were significantly better for the cohort starting in winter compared to the summer cohort. CONCLUSION: Rheumates@Work had a positive, albeit small, effect on physical activity, exercise capacity, and participation in school and physical education class in the intervention group. Improvements lasted for 12 months. Participants who started in winter showed the most improvement. Rheumates@Work had no effect on HRQoL.

AB - OBJECTIVE: Degeneration of articular cartilage is central to the pathology of osteoarthritis (OA). However, the molecular mechanisms leading to these irreversible changes are still poorly understood. This study was undertaken to investigate how changes in the chondrocyte translational apparatus may contribute to the development and progression of knee OA. METHODS: Articular cartilage from the knees of normal healthy subjects and patients with OA was used to analyze the activity of different components of the translational machinery. Chondrocytes isolated from lesional and nonlesional areas of the human OA cartilage were used to estimate the relative rate of protein synthesis by metabolic labeling. Experimental OA was induced by transection of the anterior cruciate ligament of rats to investigate changes in the translational apparatus associated with OA. The role of interleukin-1beta (IL-1beta) signaling was assessed in vitro using rat articular chondrocytes. In human or rodent knee cartilage, messenger RNA expression was analyzed by quantitative polymerase chain reaction, and protein levels were determined by immunohistochemistry and Western blotting. RESULTS: Several novel traits of OA chondrocytes were identified, including up-regulation of the serine/threonine kinases Akt-2 and Akt-3 at the posttranscriptional level and an increased rate of total protein synthesis, likely attributable to inactivation of eukaryotic initiation factor 4E binding protein 1 (4E-BP1), a known repressor of cap-dependent translation. Inactivation of 4E-BP1 was dependent on the activity of mechanistic target of rapamycin and was crucial for the up-regulation of protein synthesis in general and expression of matrix metalloproteinase 13 and ADAMTS-5 in particular. In addition, treatment of articular chondrocytes with IL-1beta led to inactivation of 4E-BP1 and up regulation of protein synthesis. CONCLUSION: Precise control of protein synthesis is vital for cartilage homeostasis, and its dysregulation contributes to the molecular pathology of OA. The results of this study therefore identify a novel set of potential therapeutic targets to ameliorate the effects of knee OA.

AB - Soft sensors are powerful tools for bioprocess monitoring due to their ability to perform online, noninvasive measurement, and possibility of detection of multiple components in cultivation media, which in turn can provide tools for the quantification of more than one metabolite/substrate/product in real time. In this work, soft sensor based on excitation-emission fluorescence is for the first time applied for the monitoring of biotransformation production of 2 phenylethanol (2-PE) by yeast strains. Main process parameters-such as optical density, glucose, and 2-PE concentrations-were determined with high accuracy and precision by fluorescence fingerprinting coupled with partial least squares regression.

PMID- 27696795 TI - Relationship Between Attitudes and Beliefs and Physical Activity in Older Adults With Knee Pain: Secondary Analysis of a Randomized Controlled Trial. AB - OBJECTIVE: To investigate how attitudes and beliefs about exercise relate to physical activity behavior in older adults with knee pain attributable to osteoarthritis (OA). METHODS: We conducted secondary data analyses of a randomized controlled trial of exercise interventions (ISRCTN: 93634563). Participants were adults >=45 years old with knee pain attributable to OA (n = 514). Crude and adjusted cross-sectional and longitudinal associations between baseline Self-Efficacy for Exercise (SEE), Positive Outcome Expectations for Exercise (POEE), Negative Outcome Expectations for Exercise scores, and physical activity level, at baseline, 3 months, and 6 months (measured by self-report using the Physical Activity Scale for the Elderly [PASE]), and important increases in physical activity level (from baseline to 6-month followup) were investigated using multiple linear and logistic regression. RESULTS: Cross sectional associations were found between SEE and PASE scores (beta = 4.14 [95% confidence interval (95% CI) 0.26, 8.03]) and POEE and PASE scores (beta = 16.71 [95% CI 1.87, 31.55]), adjusted for sociodemographic and clinical covariates. Longitudinal associations were found between baseline SEE and PASE scores at 3 months (beta = 4.95 [95% CI 1.02, 8.87]) and 6 months beta = 3.71 (0.26, 7.16), and baseline POEE and PASE at 3 months (beta = 34.55 [95% CI 20.13, 48.97]) and 6 months (beta = 25.74 [95% CI 11.99, 39.49]), adjusted for baseline PASE score and intervention arm. However, no significant associations with important increases in physical activity level were found. CONCLUSION: Greater exercise self-efficacy and more positive exercise outcome expectations were associated with higher current and future physical activity levels. These may be targets for interventions aimed at increasing physical activity.

AB - Electrostatic attraction between charged nanoparticles and oppositely charged nanopatterned polymeric films enables tailored structuring of functional nanoscopic surfaces. The bottom-up fabrication of organic/inorganic composites for example bears promising potential toward cheap fabrication of catalysts, optical sensors, and the manufacture of miniaturized electric circuitry. However, only little is known about the time-dependent adsorption behavior and the electronic or ionic charge transfer in the film bulk and at interfaces during nanoparticle assembly via electrostatic interactions. In situ electrochemical impedance spectroscopy (EIS) in combination with a microfluidic system for fast and reproducible liquid delivery was thus applied to monitor the selective deposition of negatively charged gold nanoparticles on top of positively charged poly(2-vinylpyridinium) (qP2VP) domains of phase separated lamellar poly(styrene) block-poly(2-vinylpyridinium) (PS-b-qP2VP) diblock copolymer thin films. The acquired impedance data delivered information with respect to interfacial charge alteration, ionic diffusion, and the charge dependent nanoparticle adsorption kinetics, considering this yet unexplored system. We demonstrate that the selective adsorption of negatively charged gold nanoparticles (AuNPs) on positively charged qP2VP domains of lamellar PS-b-qP2VP thin films can indeed be tracked by EIS. Moreover, we show that the nanoparticle adsorption kinetics and the nanoparticle packing density are functions of the charge density in the qP2VP domains.

AB - Independently controlling the shape anisotropy and chemical composition of multinary semiconductor particles is important for preparing highly efficient photocatalysts. In this study, we prepared ZnS-AgInS2 solid solution ((AgIn)xZn2(1-x)S2, ZAIS) nanoparticles with well-controlled anisotropic shapes, rod and rice shapes, by reacting corresponding metal acetates with a mixture of sulfur compounds with different reactivities, elemental sulfur, and 1,3 dibutylthiourea, via a two-step heating-up process. The chemical composition predominantly determined the energy gap of ZAIS particles: the fraction of Zn2+ in rod-shaped particles was tuned by the ratio of metal precursors used in the nanocrystal formation, while postpreparative Zn2+ doping was necessary to increase the Zn2+ fraction in the rice-shaped particles. The photocatalytic H2 evolution rate with irradiation to ZAIS particles dispersed in an aqueous solution was significantly dependent on the chemical composition in the case of using photocatalyst particles with a constant morphology. In contrast, photocatalytic activity at the optimum ZAIS composition, x of 0.35-0.45, increased with particle morphology in the order of rice (size: ca. 9 * ca. 16 nm) < sphere (diameter: ca. 5.5 nm) < rod (size: 4.6 * 27 nm). The highest apparent quantum yield for photocatalytic H2 evolution was 5.9% for rod-shaped ZAIS particles, being about two times larger than that obtained with spherical particles. PMID- 27696799 TI - A high-voltage and non-corrosive ionic liquid electrolyte used in rechargeable aluminum battery. AB - As a promising post-lithium battery, rechargeable aluminum battery has the potential to achieve a three-electron reaction with fully use of metal aluminum. Alternative electrolytes are strongly needed for further development of rechargeable aluminum batteries, since typical AlCl3-contained imidazole-based ionic liquids are moisture sensitive, corrosive, and with low oxidation voltage. In this letter, a kind of non-corrosive and water-stable ionic liquid obtained by mixing 1-butyl-3-methylimidazolium trifluoromethanesulfonate ([BMIM]OTF) with the corresponding aluminum salt (Al(OTF)3) is studied. This ionic liquid electrolyte has a high oxidation voltage (3.25V vs Al3+/Al) and high ionic conductivity, and a good electrochemical performance is also achieved. A new strategy, which first use corrosive AlCl3-based electrolyte to construct a suitable passageway on the Al anode for Al3+, and then use non-corrosive Al(OTF)3-based electrolyte to get stable Al/electrolyte interface, is put forward. PMID- 27696800 TI - Influence of Singlet and Charge-Transfer Excitons on the Open-Circuit Voltage of Rubrene/Fullerene Organic Photovoltaic Device. AB - We demonstrated that the open-circuit voltage (VOC) of rubrene/C60 organic photovoltaic (OPV) devices can be substantially improved by changing the rubrene thickness. A shoulder exhibited in a range of 500-550 nm was observed. This result indicated that the singlet excitons of rubrene were increased when the thickness of the rubrene layer was increased. Capacitance-voltage measurements were conducted for estimating the built-in potential of the devices. The calculated VOC was higher than that of the experiment, thus indicating that energetic losses occurred in the devices. We reused the reciprocity and revised Marcus theory for determining the charge-transfer (CT) properties of the devices. The CT properties of the CT states at the rubrene/C60 interface remained similar. The nonradiative energetic losses become smaller when the rubrene layer was increased, thus indicating the bimolecular recombination was increased. The increased recombination thermally activated the electrons in C60 into rubrene for forming the singlet excitons in rubrene. The reduction in reorganization energy indicated that the electroluminescence of rubrene was enhanced, thereby improving VOC. These results proved that the two-step thermal activation of C60 electrons and the improved VOC of rubrene were caused by the increased singlet excitons of rubrene. PMID- 27696801 TI - Field and Pretreatment-free Detection of Heavy Metal Ions in Organic Polluted Water through Alkyne-coded SERS Test Kit. AB - Field and pretreatment-free detection of heavy metal ions in organic polluted water is important but still challenging in current water pollution emergency response system. Here we report a Poly adenine-DNA-mediated approach for rationally designed alkyne-coded surface-enhanced Raman scattering (SERS) test kit, enabling rapid and simultaneous detection of Hg2+ and Ag+ by portable spectrometer, impervious to organic interferences. Due to the formation of thymine (T)-Hg2+-T and cytosine (C)-Ag+-C, highly recognizable SERS signals are rapidly detected when two different alkynes labeled gold nanoparticles (AuNPs) are induced to undergo controllable bridging upon the additive of low volume targets. For multiplex detection through portable spectrometer, the limits of detection reach 0.77 nM and 0.86 nM for Hg2+ and Ag+, respectively. Of particular significance, the proposed C=C contained Raman reporters provide an extremely effective solution for multiplex sensing in spectral silent region when the hyperspectral and fair intense optical noises originating from lower wave number region (<1800 cm-1) are inevitable under complex ambient conditions. PMID- 27696802 TI - Robust Multilayered Encapsulation for High-Performance Triboelectric Nanogenerator in Harsh Environment. AB - Harvesting biomechanical energy especially in vivo is of special significance for sustainable powering of wearable/implantable electronics. The triboelectric nanogenerator (TENG) is one of the most promising solutions considering its high efficiency, low cost, light weight, and easy fabrication, but its performance will be greatly affected if there is moisture or liquid leaked into the device when applied in vivo. Here, we demonstrate a multiple encapsulation process of the TENG to maintain its output performance in various harsh environments. Through systematic studies, the encapsulated TENG showed great reliability in humid or even harsh environment over 30 days with a stability index of more than 95%. Given its outstanding reliability, the TENG has the potential to be applied in variety of circumstances to function as a sustainable power source for self powered biomedical electronics and environmental sensing systems. PMID- 27696803 TI - Doping ZnO with Water/Alcohol-Soluble Small Molecules as Electron Transport Layers for Inverted Polymer Solar Cells. AB - By doping ZnO with porphyrin small molecules (FNEZnP-OE and FNEZnP-T) as cathode electron transport layers (ETLs), the inverted polymer solar cells (i-PSC) with PTB7:PC71BM (PTB7: polythieno[3,4-b]-thiophene-co-benzodithiophene, PC71BM: [6, 6]-phenyl-C71-butyric acid methyl ester) as the active materials exhibit enhanced device performance. While the power conversion efficiency (PCE) of the PSCs with pure ZnO ETL is 7.52%, that of the devices with FNEZnP-T-doped ZnO ETL shows a slightly improved PCE of 8.09%, and that of the PSCs with FNEZnP-OE-doped ZnO ETL is further enhanced up to 9.24% with an over 20% improvement compared to that with pure ZnO ETL. The better performance is contributed by the better interfacial contact and reduced work function induced by 9,9-bis(30-(N,N dimethylamino)propyl)-2,7-fluorenes and 3,4-bis-(2-(2-methoxy-ethoxy)-ethoxy) phenyls in the porphyrin small molecules. More importantly, the PCE is still higher than 8% even when the thickness of FNEZnP-OE-doped ZnO ETL is up to 110 nm, which are important criteria for eventually making organic photovoltaic modules with roll-to-roll coat processing. PMID- 27696804 TI - Metal-Oxide Stacked Electron Transport Layer for Highly Efficient Inverted Quantum-Dot Light Emitting Diodes. AB - We report highly efficient inverted quantum-dot light emitting diodes (QLEDs) using an Al doped ZnO (AZO)/Li doped ZnO (LZO) stack electron transport layer (ETL). An introduction of the LZO layer on AZO improved the current and power efficiencies of the green (G-) QLEDs from 10.5 to 34.0 cd A-1 and from 5.4 to 29.6 lm W-1, respectively. The red (R-), G-, and blue (B-) QLEDs fabricated in this work exhibited the maximum external quantum efficiencies (EQEs) of 8.4, 12.5, and 4.3%, respectively. It is found from time-resolved photoluminescence (PL) and transient electroluminescence (EL) decay that exciton loss at the interface between the ETL and the emission layer can be significantly reduced by introducing LZO. PMID- 27696805 TI - Reporter-Embedded SERS Tags from Gold Nanorod Seeds: Selective Immobilization of Reporter Molecules at the Tip of Nanorods. AB - Reporter embedded (RE) tags are a new generation of sensitive, stable surface enhanced Raman scattering (SERS) tags with Raman reporters embedded between gold nanoparticle (NP) cores and gold (or silver) shells. Most of the reported RE tags have been designed using Au nanospheres as a seed material. Herein, we investigated the synthesis and SERS properties of AuNR/reporter/Ag tags by using gold nanorod (AuNR) seeds with anisotropic physical and optical features. Several highlighted points were discovered, including the following: 1) The cetyltrimethylammonium bromide (CTAB) layer induced the co-existence of chemically and physically adsorbed Raman reporters on AuNR. Conventional washing of the AuNR-reporter complex with water results in the formation of an "internal external" mixed tag. To obtain a "pure" RE structure, an additional extraction step involving a CTAB solution was essential. 2) The anisotropic distribution of CTAB on AuNR resulted in the preference of the Raman reporters to adsorb to the hotspot at AuNR tip, which made it a perfect match for improving the SERS signal of the tag. 3) An anisotropic silver coating occurred with the shell thickness on the AuNR side growing much faster than the shell thickness at the tip. This feature ensured that the tag grew to a suitable size with enough silver for SERS enhancement without shadowing the effective Raman reporters at the tip too much. 4) RE tags showed better in vitro and in vivo signal stabilities compared with their external labeling counterparts. Moreover, a novel pH-sensitive SERS peak test was proposed by using 4-mercaptobenzoic acid as the Raman reporter to verify thin coverage by a silver layer. We believe this tag can be broadly applied for molecular detection and bio-imaging, and the proposed preparation and structure verification methods can provide universal guidance in the design of novel RE tags. PMID- 27696806 TI - Three-Dimensional Printing of pH-Responsive and Functional Polymers on an Affordable Desktop Printer. AB - In this work we describe the synthesis, thermal and rheological characterization, hot-melt extrusion, and three-dimensional printing (3DP) of poly(2-vinylpyridine) (P2VP). We investigate the effect of thermal processing conditions on physical properties of produced filaments in order to achieve high quality, 3D-printable filaments for material extrusion 3DP (ME3DP). Mechanical properties and processing performances of P2VP were enhanced by addition of 12 wt % acrylonitrile-butadiene-styrene (ABS), which reinforced P2VP fibers. We 3D-print P2VP filaments using an affordable 3D printer. The pyridine moieties are cross linked and quaternized postprinting to form 3D-printed pH-responsive hydrogels. The printed objects exhibited dynamic and reversible pH-dependent swelling. These hydrogels act as flow-regulating valves, controlling the flow rate with pH. Additionally, a macroporous P2VP membrane was 3D-printed and the coordinating ability of the pyridyl groups was employed to immobilize silver precursors on its surface. After the reduction of silver ions, the structure was used to catalyze the reduction of 4-nitrophenol to 4-aminophenol with a high efficiency. This is a facile technique to print recyclable catalytic objects. PMID- 27696807 TI - A Smart Antibacterial Surface Made by Photopolymerization. AB - Based on the use of photopolymerization technology, a facile and reliable method for in situ preparation of silver nanoparticles (AgNPs) within PNIPAAm functional surfaces is presented as a means to achieve non-fouling, antibacterial films. The surface properties were characterized by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), water contact angle and thermogravimetric analysis (TGA). The antibacterial and release properties of the surfaces were tested against E. coli: at 37 C (above the LCST of PNIPAAm), the functional films facilitated the attachment of bacteria, which were then killed by the AgNPs. Changing temperature to 4 C (below the LCST), swollen PNIPAAm chains led the release of dead bacteria. The results showed that AgNPs/PNIPAAm hybrid surfaces offer a "smart" antibacterial capability in response to the change of environmental temperature. PMID- 27696808 TI - Preparation and Timed Release Properties of Self-Rupturing Gels. AB - Swelling of polymeric hydrogels is sensitive to their cross-link densities. Here, we exploit this principle to prepare self-rupturing gels which are based on a commonly-used, nontoxic, and inexpensive polyelectrolyte, poly(acrylic acid), and are prepared through a simple and low-cost polymerization-based technique. The self-rupture of these covalently cross-linked gels is achieved by preparing them to have highly nonuniform cross-link densities. This heterogeneity in cross linking leads to highly nonuniform swelling, which generates stresses that are high enough to induce gel rupture. The time required for this rupture to occur depends on the difference in the cross-link densities between the adjoining gel regions, gel size, order in which the variably cross-linked gel portions are synthesized, and on the ambient pH and ionic strength. Furthermore, when these self-rupturing gels are prepared to have liquid-filled (capsule-like) morphologies, they can act as timed/delayed release devices. The self-rupture of these capsules provides a burst payload release after a preprogrammed delay, which is on the timescale of days and can be easily tuned by varying the rupture time, i.e., by varying either the cross-link nonuniformity or the pH and ionic strength of the release media. PMID- 27696809 TI - Fouling-Release Performance of Silicone Oil-Modified Siloxane-Polyurethane Coatings. AB - The effect of incorporation of silicone oils into a siloxane-polyurethane fouling release coatings system was explored. Incorporation of phenylmethyl silicone oil has been shown to improve the fouling-release performance of silicone-based fouling-release coatings through increased interfacial slippage. The extent of improvement is highly dependent upon the type and composition of silicone oil used. The siloxane-polyurethane (SiPU) coating system is a tough fouling-release solution, which combines the mechanical durability of polyurethane while maintaining comparable fouling-release performance with regard to commercial standards. To further improve the fouling-release performance of the siloxane-PU coating system, the use of phenylmethyl silicones oils was studied. Coatings formulations were prepared incorporating phenylmethyl silicone oils having a range of compositions and viscosities. Contact angle and surface energy measurements were conducted to evaluate the surface wettability of the coatings. X-ray photoelectron spectroscopy (XPS) depth profiling experiments demonstrated self-stratification of silicone oil along with siloxane to the coating-air interface. Several coating formulations displayed improved or comparable fouling release performance to commercial standards during laboratory biological assay tests for microalgae (Navicula incerta), macroalgae (Ulva linza), adult barnacles (Balanus amphitrite syn. Amphibalanus amphitrite), and mussels (Geukensia demissa). Selected silicone-oil-modified siloxane-PU coatings also demonstrated comparable fouling-release performance in field immersion trials. In general, modifying the siloxane-PU fouling-release coatings with a small amount (1-5 wt % basis) of phenylmethyl silicone oil resulted in improved performance in several laboratory biological assays and in long-term field immersion assessments. PMID- 27696811 TI - B, N-co-doped graphene supported sulfur for superior stable Li-S half cell and Ge S full battery. AB - B, N-co-doped graphene supported sulfur (S@BNG) composite is synthesized by using melamine diborate as precursor. XPS spectra illustrates that BNG with a high percentage and dispersive B, N (B: 13.47 %, N: 9.17 %) and abundant pyridinic-N and N-B/N=B bond, which show strong interaction with Li2Sx proved by simulation experiments. As cathode for Li-S half cell, S@BNG with a sulfur content of 75 % displays a high capacity of 765 mA h g-1 at 1 C even after 500 cycles with a low fading rate of 0.027 % per cycle. Even at a high sulfur loading of 4.73 mg cm-2, S@BNG still shows a high reversible areal capacity of 3.5 mA h cm-2 after 50 cycles. When S@BNG composite as cathode combines with high performance lithiated Ge anode (discharge capacity of 1138 mA h g-1 at 1 C over 1000 cycles in half cell), the assembled Ge-S full battery exhibits a superior capacity of 530 mA h g 1 at 1 C over 500 cycles. PMID- 27696810 TI - Paving the Thermal Highway with Self-Organized Nanocrystals in Transparent Polymer Composites. AB - Phonon transfer is greatly scattered in traditional polymer composites due to the unpaired phonon frequency at the polymer/filler interface. A key innovation of this work is to build continuous crystal network by self-organization and utilize it as "thermal highway" that circumvents the long-existing interfacial thermal barrier issue in traditional composites. By tuning the molecular diffusion rate of dicarboxylic acids (oxalic acid, malonic acid, and succinic acid), different crystal structures including skeletal, dendrite, diffusion-limited aggregates, and spherulite were synthesized in PVA film. These continuous crystal structures benefit the efficient phonon transfer in the composites with minimized interfacial scattering and lead to a significant thermal conductivity enhancement of up to 180% compared to that of pure polymer. Moreover, the transparent feature of these composite films provides additional benefits in display applications. The post heat treatment effect on the thermal conductivity of the composite films shows a time-dependent behavior. These uniquely structured polymer/crystal composites are expected to generate significant impacts in thermal management applications.

The energy level of ammonium anthracene increased the work function of indium tin oxide (ITO), functioning as a hole-blocker (electron transporter). Solar cells in which ITO was treated by the ammonium anthracene produced an average power conversion efficiency (PCE) of 5.8% without ZnO, the electron-transporting layer. When the ammonium anthracene was applied to ZnO, an average PCE of 8.1% was achieved, which is higher than the average PCE of 7.5% for nontreated ZnO-based devices.

AB - This paper reports a series of novel Ni-based metal-organic framework (Ni-MOFs) prepared by a facile solvothermal process. The synthetic conditions have great effects on the Ni-MOFs morphologies, porous textures, and their electrochemical performance. Improved capacitance performance was successfully realized by the in situ hybrid of Ni-MOFs with graphene oxide (GO) nanosheets (Ni-MOFs@GO). The pseudocapacitance of ca. 1457.7 F/g for Ni-MOFs obtained at 180 degrees C with HCl as the modulator was elevated to ca. 2192.4 F/g at a current density of 1 A/g for the Ni-MOFs@GO with GO contents of 3 wt %. Additionally, the capacitance retention was also promoted from ca. 83.5% to 85.1% of its original capacitance at 10 A/g even after 3000 cycles accordingly. These outstanding electrochemical properties of Ni-based MOF materials may be related to their inherent characteristics, such as the unique flower-like architecture and fascinating synergetic effect between the Ni-MOFs and the GO nanosheets.

AB - Defect engineering is regarded as one of the most active projects to regulate the chemical and physical properties of materials, which is expected to improve the photocatalytic performance of the materials. Herein, oxygen vacancies and IO3- doping are introduced into BiOI nanosheets via adding NaH2PO2, which can impact the charge carrier dynamics of BiOI photocatalysts, such as its excitation, separation, trap, and transfer. These oxygen-deficient BiOI nanosheets display excellent photocatalytic activities for degradation of gaseous formaldehyde and methyl orange under visible light irradiation, which are 5 and 3.5 times higher than the BiOI samples, respectively. Moreover, the oxygen-deficient BiOI also have superior cycling stability and can be used for practical application. This work did not only develop an effective strategy for fabricating oxygen vacancies but also offer a deep insight into the role of oxygen vacancies in enhancing photocatalysis. PMID- 27696815 TI - A Tale Of Two Luciferins: Fungal and Earthworm New Bioluminescent Systems. AB - Bioluminescence, the ability of a living organism to produce light through a chemical reaction, is one of Nature's most amazing phenomena widely spread among marine and terrestrial species. There are various different mechanisms underlying the emission of "cold light", but all involve a small molecule, luciferin, that provides energy for light-generation upon oxidation, and a protein, luciferase, that catalyzes the reaction. Different species often use different proteins and substrates in the process, which suggests that the ability to produce light evolved independently several times throughout evolution. Currently, it is estimated that there are more than 30 different mechanisms of bioluminescence. Even though the chemical foundation underlying the bioluminescence phenomenon is by now generally understood, only a handful of luciferins have been isolated and characterized. Today, the known bioluminescence reactions are used as indispensable analytical tools in various fields of science and technology. A pressing need for new bioluminescent analytical techniques with a wider range of practical applications stimulates the search and chemical studies of new bioluminescent systems. In the past few years two such systems were unraveled: those of the earthworms Fridericia heliota and the higher fungi. The luciferins of these two systems do not share structural similarity with the previously known ones. This Account will survey structure elucidation of the novel luciferins and identification of their mechanisms of action. Fridericia luciferin is a key component of a novel ATP-dependent bioluminescence system. Structural studies were performed on 0.005 mg of natural substance and revealed its unusual extensively modified peptidic nature. Elucidation of Fridericia oxyluciferin revealed that oxidative decarboxylation of a lysine fragment of luciferin supplies energy for light generation, while a fluorescent CompX moiety remains intact and serves as a light emitter. Along with luciferin, a number of its natural analogs were found in the extracts of worm biomass. They occurred to be highly unusual modified peptides comprising a set of amino acids, including threonine, aminobutyric acid, homoarginine, unsymmetrical N,N-dimethylarginine and extensively modified tyrosine. These natural compounds represent a unique peptide chemistry found in terrestrial animals and raise novel questions concerning their biosynthetic origin. Also in this Account we discuss identification of the luciferin of higher fungi 3-hydroxyhispidin which is biosynthesized by oxidation of the precursor hispidin, a known fungal and plant secondary metabolite. Furthermore, it was shown that 3-hydroxyhispidin leads to bioluminescence in extracts from four diverse genera of luminous fungi, thus suggesting a common biochemical mechanism for fungal bioluminescence.

PMID- 27696817 TI - Selective Molecularly Mediated Pseudocapacitive Separation of Ionic Species in Solution. AB - We report the development of a dual-electrode pseudocapacitive separation technology (PSST) to capture quantitatively, remotely, and in a reversible manner value-added carboxylate salts of environmental and industrial significance. The nanostructured pseudocapacitive cell exhibits elegant molecular selectivity toward ionic species: upon electrochemical oxidation, a poly(vinylferrocene) (PVF)-based anodic electrode shows high selectivity toward carboxylates based on their basicity and hydrophobicity. Simultaneously, on the other side of the electrochemical cell, a poly(anthraquinone) (PAQ)-based cathodic electrode undergoes electrochemical reduction and captures the counterions of these carboxylates. The separation and regeneration capability of the electrochemical cell was evaluated through the variations in concentration of the carboxylates in polar organic solvents (often used in electrocatalytic processes) upon electrochemical charging and neutralization of the polymeric cargo of the electrodes, respectively. The strong separation efficiency of the system was indicated by its ability to capture an individual carboxylate (acetate, formate, or benzoate) selectively over other competing ions present in solution in significant excess, with an electrosorption capacity in the range of 122-157 mg anions/gcell (polymer and CNT components on the anodic and cathodic side of the cell). The ion sorption capacity of the cell was high even after five adsorption/desorption cycles (18 000 s of continuous operation). In addition, the cell exhibited molecular selectivity even between two carboxylates (e.g., between benzoate and acetate or formate) which differ only in terms of basicity and hydrophobicity. We anticipate that this strategy can be employed as a versatile platform for selective ion separations. In particular, the functionalization of electrochemical cells with the proper polymers would enable the remote and economically viable electro-mediated separation of the desired ionic species in a quantitative and reversible manner. PMID- 27696818 TI - Homodimeric Escherichia coli Toxin CcdB (Controller of Cell Division or Death B Protein) Folds via Parallel Pathways. AB - The existence of parallel pathways in the folding of proteins seems intuitive, yet remains controversial. We explore the folding kinetics of the homodimeric Escherichia coli toxin CcdB (Controller of Cell Division or Death B protein) using multiple optical probes and approaches. Kinetic studies performed as a function of protein and denaturant concentrations demonstrate that the folding of CcdB is a four-state process. The two intermediates populated during folding are present on parallel pathways. Both form by rapid association of the monomers in a diffusion limited manner and appear to be largely unstructured, as they are silent to the optical probes employed in the current study. The existence of parallel pathways is supported by the insensitivity of the amplitudes of the refolding kinetic phases to the different probes used in the study. More importantly, interrupted refolding studies and ligand binding studies clearly demonstrate that the native state forms in a biexponential manner, implying the presence of at least two pathways. Our studies indicate that the CcdA antitoxin binds only to the folded CcdB dimer and not to any earlier folding intermediates. Thus, despite being part of the same operon, the antitoxin does not appear to modulate the folding pathway of the toxin encoded by the downstream cistron. This study highlights the utility of ligand binding in distinguishing between sequential and parallel pathways in protein folding studies, while also providing insights into molecular interactions during folding in Type II toxin-antitoxin systems.

AB - The suggested bat origin for Middle East respiratory syndrome coronavirus (MERS CoV) has revitalized the studies of other bat-derived coronaviruses with respect to interspecies transmission potential. Bat coronavirus (BatCoV) HKU9 is an important betacoronavirus (betaCoV) that is phylogenetically affiliated with the same genus as MERS-CoV. The bat surveillance data indicated that BatCoV HKU9 has been widely spreading and circulating in bats. This highlights the necessity of characterizing the virus for its potential to cross species barriers. The receptor binding domain (RBD) of the coronavirus spike (S) protein recognizes host receptors to mediate virus entry and is therefore a key factor determining the viral tropism and transmission capacity. In this study, the putative S RBD of BatCoV HKU9 (HKU9-RBD), which is homologous to other betaCoV RBDs that have been structurally and functionally defined, was characterized via a series of biophysical and crystallographic methods. By using surface plasmon resonance, we demonstrated that HKU9-RBD binds to neither SARS-CoV receptor ACE2 nor MERS-CoV receptor CD26. We further determined the atomic structure of HKU9-RBD, which as expected is composed of a core and an external subdomain. The core subdomain fold resembles those of other betaCoV RBDs, whereas the external subdomain is structurally unique with a single helix, explaining the inability of HKU9-RBD to react with either ACE2 or CD26. Via comparison of the available RBD structures, we further proposed a homologous intersubdomain binding mode in betaCoV RBDs that anchors the external subdomain to the core subdomain. The revealed RBD features would shed light on the evolution route of betaCoV.

AB - The deposition kinetics of graphene oxide (GO) onto poly(ethylene imine) (PEI) layer was characterized in situ with pulsed streaming potential (SP) measurement, and it was found that the initial rate constant (ki) was dependent on the size of GO with same surface charge density at a fixed concentration under controlled experimental conditions. Assuming the deposition was controlled by diffusion at the initial stage, ki is proportional to Rh-2/3, where Rh is the hydrodynamic radius. By flushing a GO solution through a capillary coated with PEI, the initial change rate of relative SP (dEr/dt) was obtained in 20 s and ki was measured with five different concentrations in about 2 min. Three GO samples of different sizes obtained from the same batch of raw material were characterized with pulsed SP to get ki values, and their sizes were verified with atomic force microscopy and dynamic light scattering. The experimental results are consistent with the predicted effects of the size of NPs on their deposition kinetics. PMID- 27696820 TI - Virus-like Particle Display of the alpha-Gal Epitope for the Diagnostic Assessment of Chagas Disease. AB - The alpha-Gal antigen [Galalpha(1,3)Galbeta(1,4)GlcNAcalpha] is an immunodominant epitope displayed by infective trypomastigote forms of Trypanosoma cruzi, the causative agent of Chagas disease. A virus-like particle displaying a high density of alpha-Gal was found to be a superior reagent for the ELISA-based serological diagnosis of Chagas disease and the assessment of treatment effectiveness. A panel of sera from patients chronically infected with T. cruzi, both untreated and benznidazole-treated, was compared with sera from patients with leishmaniasis and from healthy donors. The nanoparticle-alpha-Gal construct allowed for perfect discrimination between Chagas patients and the others, avoiding false negative and false positive results obtained with current state-of the-art reagents. As previously reported with purified alpha-Gal-containing glycosylphosphatidylinositol-anchored mucins, the current study also showed concentrations of anti-alpha-Gal IgG to decrease substantially in patients receiving treatment with benznidazole, suggesting that the semiquantitative assessment of serum levels of this highly abundant type of antibody can report on disease status in individual patients. PMID- 27696822 TI - Self-Assembled Peptide-Based System for Mitochondrial-Targeted Gene Delivery: Functional and Structural Insights. AB - Human mitochondrial dysfunction can lead to severe and often deadly diseases, for which there are no known cures. Although the targeted delivery of therapeutic gene to mitochondria is a promising approach to alleviate these disorders, gene carrier systems for the selective delivery of functional DNA into the mitochondria of living mammalian cells are currently unavailable. Here we rationally developed dual-domain peptides containing DNA-condensing/cell penetrating/endosome-disruptive and mitochondria-targeting sequences. Secondary structures of the dual-domain peptides were analyzed, and variations in the physicochemical properties (stability, size, and zeta potential) of peptide/DNA complexes were studied as a function of peptide-to-DNA ratio and serum addition. An optimized formulation, identified through qualitative and quantitative studies, fulfills the fundamental prerequisites for mitochondria-specific DNA delivery, successfully transfecting a high proportion (82 +/- 2%) of mitochondria in a human cell line with concomitant biocompatibility. Nuclear magnetic resonance studies confirmed the effectiveness of our bipartite peptide design with segregated functions: a helical domain necessary for mitochondrial import and an unstructured region for interaction with DNA involving lysine residues. Further analyses revealed that the lysine-specific interaction assisted the self organization of the peptide and the DNA cargo, leading to a structural arrangement within the formed complex that is crucial for its biological efficiency. Thus the reported gene vector represents a new and reliable tool to uncover the complexity of mitochondrial transfection. PMID- 27696823 TI - Pore-Free Matrix with Cooperative Chelating of Hyperbranched Ligands for High Performance Separation of Uranium. AB - A new strategy combining a pore-free matrix and cooperative chelating was proposed in the present paper in order to effectively avoid undesired nonselective physical adsorption and intraparticle diffusion caused by pores and voids in porous sorbents, and to greatly enhance uranium-chelating capability based on hyperbranched amidoxime ligands on the surface of nanodiamond particles. Thus, a pore-free, amidoxime-terminated hyperbranched nanodiamond (ND-AO) was designed and synthesized. The experimental results demonstrate that the strategy endows the as-synthesized ND-AO with the following expected features: (1) distinctively high uranium selectivity (SU = qe-U/qe-tol * 100%) from over 80% to nearly 100% over the whole weak acidity range (pH < 4.5); especially, the SU can reach up to unprecedented >91% at pH 4.5, more than 20% of selectivity increment over any analogous sorbent materials reported so far, with a uranium sorption capacity of 121 mg/g in simulated nuclear industry effluent samples containing 12 coexistent nuclide ions; (2) superfast equilibrium sorption time of <30 s; and (3) one of the highest distribution coefficients (Kd) of ~3 * 106 mL/g for U(VI) as well as a fairly high sorption capacity of 212 mg/g at pH 4.5 in pure uranium solution. The strategy could also provide an optional approach for the design and fabrication of other new high-performance sorbing materials with prospective applications in selective separation of other interested metal ions. PMID- 27696825 TI - Controlled Delivery of Extracellular ROS Based on Hematoporphyrin-Incorporated Polyurethane Film for Enhanced Proliferation of Endothelial Cells. AB - The principle of photodynamic treatment (PDT) involves the administration of photosensitizer (PS) at diseased tissues, followed by light irradiation to produce reactive oxygen species (ROS). In cells, a moderate increase in ROS plays an important role as signaling molecule to promote cell proliferation, whereas a severe increase of ROS causes cell damage. Previous studies have shown that low levels of ROS stimulate cell growth through PS drugs-treating PDT and nonthermal plasma treatment. However, these methods have side effects which are associated with low tissue selectivity and remaining of PS residues. To overcome such shortcomings, we designed hematoporphyrin-incorporated polyurethane (PU) film induced generation of extracellular ROS with singlet oxygen and free radicals. The film can easily control ROS production rate by regulating several parameters including light dose, PS dose. Also, its use facilitates targeted delivery of ROS to the specific lesion. Our study demonstrated that extracellular ROS could induce the formation of intracellular ROS. In vascular endothelial cells, a moderated increase in intracellular ROS also stimulated cell proliferation and cell cycle progression by accurate control of optimum levels of ROS with hematoporphyrin-incorporated polymer films. This modulation of cellular growth is expected to be an effective strategy for the design of next-generation PDT. PMID- 27696824 TI - Maintenance and Function of a Plant Chromosome in Human Cells. AB - Replication, segregation, gene expression, and inheritance are essential features of all eukaryotic chromosomes. To delineate the extent of conservation of chromosome functions between humans and plants during evolutionary history, we have generated the first human cell line containing an Arabidopsis chromosome. The Arabidopsis chromosome was mitotically stable in hybrid cells following cell division, and initially existed as a translocated chromosome. During culture, the translocated chromosomes then converted to two types of independent plant chromosomes without human DNA sequences, with reproducibility. One pair of localization signals of CENP-A, a marker of functional centromeres was detected in the Arabidopsis genomic region in independent plant chromosomes. These results suggest that the chromosome maintenance system was conserved between human and plants. Furthermore, the expression of plant endogenous genes was observed in the hybrid cells, implicating that the plant chromosomal region existed as euchromatin in a human cell background and the gene expression system is conserved between two organisms. The present study suggests that the essential chromosome functions are conserved between evolutionarily distinct organisms such as humans and plants. Systematic analyses of hybrid cells may lead to the production of a shuttle vector between animal and plant, and a platform for the genome writing. PMID- 27696826 TI - Sulforhodamine Nanothermometer for Multiparametric Fluorescence Lifetime Imaging Microscopy. AB - Live cells function within narrow limits of physiological temperature (T) and O2 and metabolite concentrations. We have designed a cell-permeable T-sensitive fluorescence lifetime-based nanoprobe based on lipophilic sulforhodamine, which stains 2D and 3D cell models, shows cytoplasmic localization, and has a robust response to T (~0.037 ns/K). Subsequently, we evaluated the probe and fluorescence lifetime imaging microscopy (FLIM) technique for combined imaging of T and O2 gradients in metabolically active cells. We found that in adherent 2D culture of HCT116 cells intracellular T and O2 are close to ambient values. However, in 3D spheroid structures having size >200 MUm, T and O2 gradients become pronounced. These microgradients can be enhanced by treatment with mitochondrial uncouplers or dissipated by drug-induced disaggregation of the spheroids. Thus, we demonstrate the existence of local microgradients of T in 3D cell models and utility of combined imaging of O2 and T. PMID- 27696827 TI - Detection of Ligand-Induced Conformational Changes in Oligonucleotides by Second Harmonic Generation at a Supported Lipid Bilayer Interface. AB - There is a high demand for characterizing oligonucleotide structural changes associated with binding interactions as well as identifying novel binders that modulate their structure and function. In this study, second-harmonic generation (SHG) was used to study RNA and DNA oligonucleotide conformational changes associated with ligand binding. For this purpose, we developed an avidin-based biotin capture surface based on a supported lipid bilayer membrane. The technique was applied to two well-characterized aptamers, both of which undergo conformational changes upon binding either a protein or a small molecule ligand. In both cases, SHG was able to resolve conformational changes in these oligonucleotides sensitively and specifically, in solution and in real time, using nanogram amounts of material. In addition, we developed a competition assay for the oligonucleotides between the specific ligands and known, nonspecific binders, and we demonstrated that intercalators and minor groove binders affect the conformation of the DNA and RNA oligonucleotides in different ways upon binding and subsequently block specific ligand binding in all cases. Our work demonstrates the broad potential of SHG for studying oligonucleotides and their conformational changes upon interaction with ligands. As SHG offers a powerful, high-throughput screening approach, our results here also open an important new avenue for identifying novel chemical probes or sequence-targeted drugs that disrupt or modulate DNA or RNA structure and function. PMID- 27696828 TI - Structural Studies of a Complex Between Endothelial Nitric Oxide Synthase and Calmodulin at Physiological Calcium Concentration. AB - The small acidic protein Calmodulin (CaM) serves as a Ca2+ sensor and control element for many enzymes including nitric oxide synthase (NOS) enzymes that play major roles in key physiological and pathological processes. CaM binding causes a conformational change in NOS to allow for the electron transfer between the reductase and oxygenase domains through a process that is thought to be highly dynamic. In this report, NMR spectroscopy was used to determine the solution structure of the endothelial NOS (eNOS) peptide in complex with CaM at the lowest Ca2+ concentration (225 nM) required for CaM to bind to eNOS and corresponds to a physiological elevated Ca2+ level found in mammalian cells. Under these conditions, the CaM-eNOS complex has a Ca2+-replete C-terminal lobe bound the eNOS peptide and a Ca2+ free N-terminal lobe loosely associated to the eNOS peptide. With increasing Ca2+ concentration, the binding of Ca2+ by the N-lobe of CaM results in a stronger interaction with the C-terminal region of the eNOS peptide and increased alpha-helical structure of the peptide that may be part of the mechanism resulting in electron transfer from the FMN to the heme in the oxygenase domain of the enzyme. SPR studies performed under the same conditions show Ca2+ concentration dependent binding kinetics were consistent with the NMR structural results. This investigation shows that structural studies performed under more physiological relevant conditions provide information on subtle changes in structure that may not be apparent when experiments are performed in excess Ca2+ concentrations. PMID- 27696829 TI - Deconstructing Methane Emissions from a Small Northern European River: Hydrodynamics and Temperature as Key Drivers. AB - Methane (CH4) emissions from small rivers and streams, particularly via ebullition, are currently under-represented in the literature. Here, we quantify the methane effluxes and drivers in a small, Northern European river. Methane fluxes are comparable to those from tropical aquatic systems, with average emissions of 320 mg CH4 m-2 d-1. Two important drivers of methane flux variations were identified in the studied system: 1) temperature-driven sediment methane ebullition and 2) flow-dependent contribution suspected to be hydraulic exchange with adjacent wetlands and small side-bays. This flow-dependent contribution to river methane loading is shown to be negligible for flows less than 4 m3 s-1 and greater than 50% as flows exceed 7 m3 s-1. While the temperature-ebullition relationship is comparable to other systems, the flow rate dependency has not been previously demonstrated. In general, we found that about 80% of the total emissions were due to methane bubbles. Applying ebullition rates to global estimates for fluvial systems, which currently are not considered, could dramatically increase emission rates to ranges from lakes or wetlands. This work illustrates that small rivers can emit significant methane and highlights the need for further studies on the link between hydrodynamics and connected wetlands. PMID- 27696830 TI - Effect of Biodiesel Fuels on Real-World Emissions of Passenger Locomotives. AB - Few data are available regarding the effect of biodiesel on exhaust emission rates of two-stroke engines used in many passenger locomotives. Using a portable emissions measurement system (PEMS), duty cycle average nitrogen oxides (NOx), hydrocarbons (HC), carbon monoxide (CO), particulate matter (PM), and carbon dioxide (CO2) emission rates were measured for three locomotives operating on ultra-low sulfur diesel (ULSD) and soy-based B10, B20, and B40 biodiesel blends. Measurements were conducted in the rail yard (RY) and over-the-rail (OTR) during passenger service. Compared to ULSD, B20 biodiesel had statistically significant average emission rate reductions in the RY of 58% for CO, 45% for PM, and 6% CO2 and OTR of 59% for HC, 50% for CO, 26% for PM, and 5% for CO2. The average differences in NOx emission rates for both the RY and OTR, and HC in the RY, were not statistically significant. The OTR findings typically agreed qualitatively with the RY findings; however, OTR provides a better basis for estimating the real-world impact of fuel switching. The results indicate substantial potential to reduce in-use locomotive emissions for existing older locomotives, with the exception of NOx. PMID- 27696831 TI - Synthesis and Magnetic Characterization of Fe(III)-Based 9-Metallacrown-3 Complexes Which Exhibit Magnetorefrigerant Properties. AB - The structural characterization and magnetic properties of three related 9 metallacrown-3 (9-MC-3) structures are reported. Each of these iron complexes is shown to exhibit significant magnetic refrigerant properties. FeIII(acetate)3[9 MCFeIIIN(shi)-3](MeOH)3.MeOH.7H2O (1-OAc) and FeIII(benzoate)3[9-MCFeIIIN(shi) 3](MeOH)3.MeOH.4H2O (1-OBz) are structurally analogous tetranuclear iron(III) clusters which exhibit drastically different magnetic properties, due to differences in intermolecular and intramolecular pi interactions which affect superexchange. 1-OAc displays a magnetocaloric effect with a maximum entropy change of -DeltaSm = 15.4 J kg-1 K-1 at T = 3 K and an applied field change of MUoDeltaH = 7 T, whereas 1-OBz exhibits a maximum -DeltaSm = 7.4 J kg-1 K-1 at T = 7 K and MUoDeltaH = 7 T and displays an inverse magnetocaloric effect at lower temperatures and field changes. 1-OAc has -DeltaSm values comparable to those of other Fe-based MCE materials and displays a significant MCE at lower applied fields, with -DeltaSm = 11.2 J kg-1 K-1 at 3 K and MUoDeltaH = 3 T. The tetranuclear core of 1 may be linked with isophthalate to form an octanuclear FeIII2(isophthalate)3[9-MCFeIIIN(shi)-3]2 dimer (2) that crystallizes in a honeycomb packing arrangement and exhibits solvation-dependent magnetic properties. The MCE for this molecule ranges from -DeltaSm = 9.9 J kg-1 K-1 at T = 5 K and MUoDeltaH = 7 T, when the pores of the material are highly occupied with solvent, to -DeltaSm = 5.4 J kg-1 K-1, when the system is fully desolvated. PMID- 27696832 TI - Aluminum-Cycle Ion Exchange Process for Hardness Removal: A New Approach for Sustainable Softening. AB - From a sustainability viewpoint, sodium exchange softening, although used widely, is under scrutiny due to its production of excess Na-laden spent regenerant and subsequent discharge to the environment. Many arid regions are introducing regulations disallowing dumping of concentrated sodium salts, the residuals from popular Na-exchange softening. The sodium content of the softened water is, also, always higher than in the feed, which poses a dietary health concern when used for drinking or cooking. An efficient, easy-to-operate hardness removal process with reduced sodium in both the treated water and in the spent regenerant is an unmet global need. Use of a cation exchange resin in Al3+-form for hardness removal, that is, exchange of divalent Ca2+ or Mg2+ with trivalent Al3+, is counterintuitive, and this is particularly so, because the aluminum ion to be exchanged has higher affinity than calcium. Nevertheless, ion exchange accompanied by precipitation of aluminum hydroxide allows progress of the cation exchange reaction leading to hardness removal. Experimental results demonstrated that calcium can be consistently removed for multiple cycles using a stoichiometric amount of AlCl3 as the regenerant. The process essentially operates at the maximum possible thermodynamic efficiency: removal of one equivalent of Ca2+ corresponds to use of one equivalent of Al3+ as a regenerant. During the Al-cycle process there is no increase in Na+ concentration and partial reduction in the total dissolved solids (TDS) of the treated water. It is noteworthy that the ion-exchange resin used, components of the fixed-bed column and operational protocol are nearly the same as traditional softening processes on Na-cycle. Thus, existing Na-cycle systems can be retrofitted into Al-cycle operation without major difficulty. PMID- 27696833 TI - In-Plate and On-Plate Structural Control of Ultra-Stable Gold/Silver Bimetallic Nanoplates as Redox Catalysts, Nanobuilding Blocks, and Single-Nanoparticle Surface-Enhanced Raman Scattering Probes. AB - Noble metal bimetallic nanomaterials have attracted a great deal of attention owing to the strong correlation between their morphology and chemical and physical properties. Even though the synthetic strategies for controlling the shapes of monometallic nanomaterials such as gold (Au) and silver (Ag) are well developed, limited advances have been made with Au/Ag bimetallic nanomaterials to date. In this work, we demonstrate a highly complex in-plate and on-plate structural control of Au/Ag bimetallic nanoplates (Au/AgBNPLs) in contrast to conventional, simply structured, 1D and 2D, branched, and polyhedral nanomaterials. The polymer used in the synthesis of seeds plays a critical role in controlling the structure of the Au/AgBNPLs. The Au/AgBNPLs exhibit exceptionally high chemical stability against various chemical etchants and a versatile catalytic reactivity with biologically and environmentally relevant chemical species. Significantly, the reversible assembly formation of the Au/AgBNPLs is demonstrated by carrying out the surface-functionalization of the materials with thiol DNA, emphasizing the potential applications of the Au/AgBNPLs in various diagnostic and therapeutic purposes. Finally, the surface enhanced Raman scattering (SERS) properties of the Au/AgBNPLs are experimentally and theoretically investigated, demonstrating a substantial potential of the Au/AgBNPLs as single-nanoparticle SERS probes. Electron microscopy, UV-vis spectroscopy, selected area electron diffraction (SAED), and energy-dispersive X ray (EDX) spectroscopy are employed to analyze the structure and composition of the Au/AgBNPLs at the atomic level. PMID- 27696835 TI - Effect of H-Bonding on Order Amplification in the Growth of a Supramolecular Polymer in Water. AB - While a great deal of knowledge on the roles of hydrogen bonding and hydrophobicity in proteins have resulted in the creation of rationally designed and functional peptidic structures, the roles of these forces on purely synthetic supramolecular architectures in water have proven difficult to ascertain. Focusing on a 1,3,5-benzenetricarboxamide (BTA) based supramolecular polymer, we have designed a molecular modeling strategy to dissect the energetic contributions involved in the self-assembly (electrostatic, hydrophobic, etc.) upon growth of both ordered BTA stacks and random BTA aggregates. Utilizing this set of simulations, we have unraveled the cooperative mechanism for polymer growth, where a critical size must be reached in the aggregates before emergence and amplification of order into the experimentally observed fibers. Furthermore, we have found that the formation of ordered fibers is favored over disordered aggregates solely on the base of electrostatic interactions. Detailed analysis of the simulation data suggests that H-bonding is a major source of this stabilization energy. Experimental and computational comparison with a newly synthesized 1,3,5-benzenetricarboxyester (BTE) derivative, lacking the ability to form the H-bonding network, demonstrated that this BTE variant is also capable of fiber formation, albeit at a reduced persistence length. This work provides unambiguous ev-idence for the key 1D driving force of hydrogen bonding in enhancing the persistency of monomer stacking and amplifying the lev-el of order into the growing supramolecular polymer in water. Our computational approach provides an important relationship di-rectly linking the structure of the monomer to the structure and properties of the supramolecular polymer. PMID- 27696834 TI - Combining Leaching and Passive Sampling To Measure the Mobility and Distribution between Porewater, DOC, and Colloids of Native Oxy-PAHs, N-PACs, and PAHs in Historically Contaminated Soil. AB - Different methods to quantify soil porewater concentrations of contaminants will provide different types of information. Passive sampling measurements give freely dissolved porewater concentrations (Cpw,free), while leaching tests provide information on the mobile concentration (Cpw,leach), including contaminants associated with dissolved organic carbon (DOC) and particles/colloids in the porewater. This study presents a novel combination of these two measurements, to study the sorption and mobility of polycyclic aromatic compounds (PACs) to DOC and particulate organic carbon (POC) in 10 historically contaminated soils. The PACs investigated were polycyclic aromatic hydrocarbons (PAHs), oxygenated-PAHs, and nitrogen containing heterocyclic PACs. Observed Cpw,leach was up to 5 orders of magnitude higher than Cpw,free; implying large biases when Cpw,leach is used to assess bioavailability or soil partitioning. Sorption of PACs to DOC and POC was important for the mobility of compounds with log KOW > 4. Average DOC/water partitioning coefficients (KDOC) correlated well with KOW (log KDOC = 0.89 * log KOW +1.03 (r2 = 0.89)). This relationship is likely more accurate for historically contaminated soils than previously published data, which suffer from artifacts caused by problems in measuring Cpw,free correctly or not using historically contaminated soils. POC/water-partitioning coefficients (KPOC) were orders of magnitude larger than corresponding KDOC, suggesting sorption to mobile particles/colloids is the dominant mechanism for PAC mobility. PMID- 27696836 TI - Regioselective Atomic Layer Deposition in Metal-Organic Frameworks Directed by Dispersion Interactions. AB - The application of atomic layer deposition (ALD) to metal-organic frameworks (MOFs) offers a promising new approach to synthesize designer functional materials with atomic precision. While ALD on flat substrates is well established, the complexity of the pore architecture and surface chemistry in MOFs present new challenges. Through in situ synchrotron X-ray powder diffraction, we visualize how the deposited atoms are localized and redistribute within the MOF during ALD. We demonstrate that the ALD is regioselective, with preferential deposition of oxy-Zn(II) species within the small pores of NU-1000. Complementary density functional calculations indicate that this startling regioselectivity is driven by dispersion interactions associated with the preferen-tial adsorption sites for the organometallic precursors prior to reaction. PMID- 27696837 TI - Kinetic studies of Pt carbonate mediated, room temperature, oxidation of carbon monoxide by oxygen over Pt/Al2O3 using combined, time resolved, XAFS, DRIFTS and mass spectrometry. AB - The kinetics involved in a recently revealed ambient temperature mechanism for the catalytic oxidation of carbon monoxide by oxygen over a 5 wt% Pt/Al2O3 catalyst are evaluated within a periodic, plug flow, redox operation paradigm using combined mass spectrometry (MS), diffuse reflectance infrared spectroscopy (DRIFTS) and time resolved Pt L3 edge XAFS. DRIFTS demonstrates that the most active species is a high wavenumber (ca. 1685 cm-1) carbonate that we associate directly with a room temperature redox process (as observed with XAFS) occurring on a fraction of the Pt atoms. Pt carbonate formation (1685 cm-1) under CO and reaction to yield CO2 is shown to be extremely rapid and subject to an average apparent activation energy (Eapp), across the techniques applied, of 8.7 kJ mol 1, within the temperature range investigated (276 - 343 K). Re-oxidation of Pt (XANES) and subsequent CO2 production mediated by Pt carbonates under O2 (MS/IR) displays a first order dependence upon O2 partial pressure and a negative dependence upon the coverage of CO adsorbed upon the Pt nanoparticles also present in this catalyst. This oxidative regeneration/CO2 production step is subject to an apparent activation energy (Eapp) of 56.5 (+/-5) kJ mol-1 and is kinetically limited by desorption of molecular CO from Pt nanoparticles. This process is also subject to an induction time that depends upon the partial pressure of O2 indicative of a direct interaction of O2 with molecular CO adsorbed on the nanoparticles that promotes CO desorption. Lastly, a minority reactive state producing CO2 in the oxidising cycle that displays no dependence upon the CO coverage of the nanoparticles can be induced through simple thermal treatment of the catalyst. These results are discussed in terms of the number and types of species present within the reactive system and in terms of the wider possibilities for the development of effective low temperature CO oxidation using Pt/Al2O3 catalysts. PMID- 27696838 TI - Commute Maps: Separating Slowly Mixing Molecular Configurations for Kinetic Modeling. AB - Identification of the main reaction coordinates and building of kinetic models of macromolecular systems require a way to measure distances between molecular configurations that can distinguish slowly interconverting states. Here we define the commute distance that can be shown to be closely related to the expected commute time needed to go from one configuration to the other, and back. A practical merit of this quantity is that it can be easily approximated from molecular dynamics data sets when an approximation of the Markov operator eigenfunctions is available, which can be achieved by the variational approach to approximate eigenfunctions of Markov operators, also called variational approach of conformation dynamics (VAC) or the time-lagged independent component analysis (TICA). The VAC or TICA components can be scaled such that a so-called commute map is obtained in which Euclidean distance corresponds to the commute distance, and thus kinetic models such as Markov state models can be computed based on Euclidean operations, such as standard clustering. In addition, the distance metric gives rise to a quantity we call total kinetic content, which is an excellent score to rank input feature sets and kinetic model quality. PMID- 27696841 TI - Wavelength Selective Generation of Aryl Radicals and Aryl Cations for Metal-Free Photoarylations. AB - Photochemical reactions have become an important tool for organic chemists. Visible (solar) light can be conveniently adopted, however, only when using colored organic compounds or in photocatalyzed processes induced by visible light absorbing photocatalysts. Herein we demonstrate that a photolabile, colored moiety could be incorporated in a colorless organic compound with the aim of generating highly reactive intermediates upon exposure to visible (solar) light. Arylazo sulfones, colored thermally stable derivatives of aryl diazonium salts, were used as valuable substrates for the photoinduced metal-free synthesis of (hetero)biaryls with no need of a (photo)catalyst or of other additives to promote the reaction. Noteworthy, selective generation of aryl radicals and aryl cations can be attained at will by varying the irradiation conditions (visible light for the former and UVA light for the latter).

AB - As dysregulation of matrix metalloproteinase (MMP) activity is associated with a wide range of pathophysiological processes like cancer, atherosclerosis, and arthritis, MMPs represent a valuable target for the development of new therapeutics and diagnostic tools. We herein present the chiral pool syntheses, in vitro evaluation, and SAR studies of a series of d- and l-proline- as well as of (4R)-4-hydroxy-l-proline-derived MMP inhibitors possessing general formula 1. Some of the synthesized hydroxamic acids were found to be potent MMP inhibitors with IC50 values in the nanomolar range, also demonstrating no off-target effects toward the other tested Zn2+-dependent metalloproteases (ADAMs and meprins). Utilizing the structure of the (2S,4S)-configured 4-hydroxyproline derivative 4, a selective picomolar inhibitor of MMP-13, the radiolabeled counterpart [18F]4 was successfully synthesized. The radiotracer's biodistribution in mice as well as its serum stability were evaluated for assessing its potential use as a MMP-13 targeting PET imaging agent. PMID- 27696840 TI - Relationship of Soluble Grape-Derived Proteins to Condensed Tannin Extractability during Red Wine Fermentation. AB - In red winemaking, the extractability of condensed tannins (CT) can vary considerably even under identical fermentation conditions, and several explanations for this phenomenon have been proposed. Recent work has demonstrated that grape pathogenesis-related proteins (PRPs) may limit retention of CT added to finished wines, but their relevance to CT extractability has not been evaluated. In this work, Vitis vinifera and interspecific hybrids (Vitis ssp.) from both hot and cool climates were vinified under small-scale, controlled conditions. The final CT concentration in wine was well modeled from initial grape tannin and juice protein concentrations using the Freundlich equation (r2= 0.686). In follow-up experiments, separation and pretreatment of juice by bentonite, heating, freezing, or exogenous tannin addition reduced protein concentrations in juices from two grape varieties. The bentonite treatment also led to greater wine CT for one of the varieties, indicating that prefermentation removal of grape protein may be a viable approach to increasing wine CT.

AB - A mechanism study to identify the elements that control the chemoselectivity of metal-catalyzed N-atom transfer reactions of styryl azides is presented. Our studies show that the proclivity of the metal N-aryl nitrene to participate in sp3-C-H bond amination or electrocyclization reactions can be controlled by either the substrate or the catalyst. Electrocyclization is favored for mono-beta substituted and sterically noncongested styryl azides, whereas sp3-C-H bond amination through an H-atom abstraction-radical recombination mechanism is preferred when a tertiary allylic reaction center is present. Even when a weakened allylic C-H bond is present, our data suggest that the indole is still formed through an electrocyclization instead of a common allyl radical intermediate. The site selectivity of metal N-aryl nitrenes was found to be controlled by the choice of catalyst: Ir(I)-alkene complexes trigger electrocyclization processes while Fe(III) porphyrin complexes catalyze sp3-C-H bond amination in substrates where Rh2(II) carboxylate catalysts provide both products. PMID- 27696845 TI - Conversion of Thin Stillage Compounds using Endemic Bacteria Augmented with Lactobacillus panis PM1B. AB - A consortium of organisms endemic in wheat-based thin stillage (W-TS) obtained from a commercial ethanol production converts glycerol to 1,3-propanediol (1,3 PD) and lactic acid to acetic acid. We sought to improve conditions for 1,3-PD and acetic acid production to be used in future studies of industrial isolation of these compounds from two-stage fermentation. Occasionally stillage fermentation proceeded slowly but an inoculum of Lactobacillus panis PM1B augmented both fermentation rate and extent. Fermentation rate and product yield were enhanced by adjusting pH to 5 daily, adding glucose and glycerol (molar ratio 0.1:1), adding freeze-dried W-TS, and adding vitamins (B2, B3, and B12). 1,3-PD and 3-HPA did not inhibit 1,3-PD production during fermentation. Moreover, agitation did not improve fermentation rate or extent. Corn sugar was a suitable substitute for glucose. Fermentation was performed at both 20 and 150 L, with 1,3 PD production of 2% (w/v, 20 g/L) being routinely achieved or exceeded. PMID- 27696846 TI - Identification and Chemical Standardization of Licorice Raw Materials and Dietary Supplements Using UHPLC-MS/MS. AB - Defined as the roots and underground stems of principally three Glycyrrhiza species, G. glabra L., G.uralensis Fish. ex DC. and G. inflata Batalin, licorice has been used as a medicinal herb for millennia and is marketed as root sticks, powders and extracts. Identity tests described in most pharmacopeial monographs enabled the distinction of Glycyrrhiza species. Accordingly, an ultrahigh performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) assay using the method of standard addition was developed to quantify 14 licorice components (liquiritin, isoliquiritin, liquiritin apioside, isoliquiritin apioside, licuraside, liquiritigenin, isoliquiritigenin, glycyrrhizin, glycyrrhetinic acid, glabridin, glycycoumarin, licoricidin, licochalcone A, and p hydroxybenzylmalonic acid), representing several natural product classes including chalcones, flavanones, saponins, and isoflavonoids. Using this approach, G. glabra, G. uralensis and G. inflata in a variety of forms including root powders and extracts as well as complex dietary supplements could be differentiated and chemically standardized without concerns due to matrix effects. PMID- 27696847 TI - Study of the Vibrational Spectra and Absorption Cross Sections of 1-chloro-1 fluoroethene by a Joint Experimental and Ab Initio Approach. AB - The gas-phase infrared spectra of 1-chloro-1-fluoroethene (geminal chloro fluoroethene, ClFC=CH2, 1,1-C2H2ClF) were recorded at medium resolution in the range 400 - 6400 cm-1 and the vibrational analysis led to revise the previous assignments for the nu11 (A'' symmetry), nu2 (A' symmetry) and nu1 (A' symmetry) bands. Besides the fundamentals, all the most relevant spectral features were interpreted in terms of overtone and combination bands, thus obtaining an accurate description of the vibrational structure of ClFC=CH2. Accurate measurements of absorption cross section spectra were carried out and integrated band intensity data were determined. High-level ab initio calculations of harmonic and anharmonic force fields thoroughly supported and guided the analysis and the disentangling of the several strongly coupled polyads involving many vibrational levels. Diagonalization of the effective Hamiltonian with the off diagonal elements involving several Fermi and Darling-Dennison resonance coefficients computed by the theoretical cubic and quartic force constants provided the predicted energy levels in good agreement with the vibrational assignments. The calculated infrared intensities, obtained by taking into account anharmonic corrections, were compared to the accurate experimental absorption cross section data here determined.

AB - Explicit solvent modeling of absorption spectra of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide has been performed. Fourier transform of autocorrelation function of the dipole moment calculated from ab initio molecular dynamics simulations has been used to obtain the IR spectrum of the bulk liquid. A sequential MD/TD DFT procedure has been applied to calculate the UV-vis spectrum. Description of both spectra by explicit solvent model improves with respect to gas phase calculations or implicit solvent with good agreement between computed spectra and the experimental data. The major factor contributing to the improvement has been attributed to better description of structures of cation anion pairs sampled from molecular dynamics simulations. Ab initio molecular dynamics with Fourier transform has been demonstrated to be a powerful methodology to calculate bulk IR spectra of ionic liquids. PMID- 27696849 TI - Carbon-Coated Nickel Phosphide Nanosheets as Efficient Dual-Electrocatalyst for Overall Water Splitting. AB - Low-cost and efficient electrocatalysts for overall water splitting are in high demand for a wide range of applications across renewable and clean energy. Here, we report a simple one-step synthesis of three-dimensional (3D) carbon-coated Ni8P3 nanosheet array as bifunctional catalyst for both hydrogen evolution reactions (HER) and oxygen evolution reactions (OER). The nanosheet array possesses low overpotentials, high current densities and small Tafel slopes in both HER and OER, and shows high electrocatalytic activities and long-term stability. The carbon layer with high electric conductivity serves not only as a protective layer to prevent Ni8P3 dissolution, but also as an active layer to decrease the electrocatalysis overpotential. The nanosheet array has HER outstanding activity in both acid and alkaline media. Its superior performance in OER can be due to the synergistic interaction at the Ni8P3/NiOx heterojunction. Furthermore, cell voltage as low as 1.65 V can achieve 10 mA cm-2 current density for full water splitting in an alkaline water electrolyzer, indicating potential application of C@ Ni8P3 as bifunctional catalyst for clean and renewable energy utilization. PMID- 27696851 TI - Design of Amphiphilic Polymers via Molecular Dynamics Simulations. AB - Extensive all-atom molecular dynamics simulations were carried out on three novel amphiphilic homopolymers in explicit polar and nonpolar solvent environments. These nonlinear polymers have potential applications in drug delivery and consisted of 32 repeating bifurcated amphiphilic side chains bound to an alkynyl functionalized cyclic framework. All of the polymer systems investigated have the same backbone and hydrophobic dodecyl side chains and differ only in the nature of the hydrophilic side chains. This report focuses on the solvent polarity induced conformational changes exhibited as a result of the different hydrophilic modifications. Our simulations of polymer microenvironment provides useful information about the amphiphilic phase segregation that drives the formation of normal micelle-like and reverse micelle-like nanostructures that are expected to occur in response to solvents of varying polarities. PMID- 27696850 TI - Mapping the Competition between Exciton Dissociation and Charge Transport in Organic Solar Cells. AB - The competition between exciton dissociation and charge transport in organic solar cells comprising poly(3-hexylthiophene) [P3HT] and phenyl-C61-butyric acid methyl ester [PCBM] is investigated by correlated scanning confocal photoluminescence and photocurrent microscopies. Contrary to the general expectation that higher photoluminescence quenching is indicative of higher photocurrent, microscale mapping of bulk-heterojunction solar-cell devices shows that photoluminescence quenching and photocurrent can be inversely proportional to one another. To understand this phenomenon, we construct a model system by selectively laminating a PCBM layer onto a P3HT film to form a PCBM/P3HT planar junction on half of the device and a P3HT single junction on the other half. Upon thermal annealing to allow for interdiffusion of PCBM into P3HT, an inverse relationship between photoluminescence quenching and photocurrent is observed at the boundary between the PCBM/P3HT junction and P3HT layer. Incorporation of PCBM in P3HT works to increase photoluminescence quenching, consistent with efficient charge separation, but conductive atomic force microscopy measurements reveal that PCBM acts to decrease P3HT hole mobility, limiting the efficiency of charge transport. This suggests that photoluminescence-quenching measurements should be used with caution in evaluating new organic materials for organic solar cells. PMID- 27696852 TI - Multifunctional porous organic polymers: tuning of porosity, CO2 and H2 storage and visible-light-driven photocatalysis. AB - A series of porous organic polymers (POPs) were fabricated based on the boron dipyrromethene (BODIPY) core. The variation of the substituents in the BODIPY core and the fine tuning of the Sonogashira polycondenzation reaction with 1,3,5 triethynylbenzene led to the formation of POPs with a wide range of surface area and porosity. A tenfold increase in surface area from 73 m2g-1 in BDT1a polymer to 1010 m2g-1 in BDT3 was obtained. Simultaneously, the porosity was changed from mesoporous to ultramicroporous. The surface area of BDT3 turned out to be the highest reported so far for BODIPY based POPs. Molecular dynamics simulation coupled with Grand Canonical Monte Carlo simulations revealed the effect of substituents alkyl groups and rigidity of the core structures on the surface properties of the POPs. Detailed gas adsorption studies of the polymers revealed a high uptake of CO2 and H!2. The highest uptake capacity of 16.5 wt. % for CO2 at 273 K and 2.2 wt.% for H!2 at 77 K was observed for BDT3 at 1 bar pressure. Isosteric heat of adsorption (Qst) of BDT3 for CO2 was found to be as high as 30.6 kJ mol-1. Electron paramagnetic resonance studies revealed the generation of singlet oxygen upon photoexcitation of these polymers. The BODIPY based POPs turned out to be excellent catalysts for visible-light-driven photooxidation of thioanisole. The present study establishes BODIPY based POPs as a new class of multifunctional materials. PMID- 27696854 TI - Optimization of Bi3+ in upconversion nanoparticles induced simultaneous enhancement of near-infrared optical and X-ray computed tomography imaging capability. AB - Bioimaging probes have been extensive studied for many years, while it is still a challenge to further improve the image quality for precise diagnosis in clinical medicine. Here, monodisperse NaGdF4:Yb3+,Tm3+,x% Bi3+ (abbreviated as GYT-x% Bi3+, x = 0, 5, 10, 15, 20, 25, 30) upconversion nanoparticles (UCNPs) have been prepared through solvothermal method. The near-infrared upconversion emission intensity of GYT-25% Bi3+ has been enhanced remarkably than that of NaGdF4:Yb3+,Tm3+ (GYT) with a factor of ~60. Especially, the near-infrared upconversion emission band centered at 802 nm is 150 times stronger than the blue emission band of GYT-25% Bi3+ UCNPs. Such high ratio of NIR/blue UCL intensity could reduce the damage to tissues in bioimaging process. The possibility of using GYT-25% Bi3+ UCNPs with strong near-infrared upconversion emission for optical imaging in vitro and in vivo was performed. Encouragingly, the UCL imaging penetration depth can be achieved as deep as 20 mm. Importantly, GYT-25% Bi3+ UCNPs exhibit a much higher X-ray computed tomography (CT) contrast efficiency than GYT and iodine-based contrast agent under the same clinical conditions, due to the high X-ray attenuation coefficient of bismuth. Hence, simultaneous remarkable enhancement of NIR emission and X-ray CT signal in upconversion nanoparticles could be achieved by optimizing the doping concentration of Bi3+ ions. Additionally, Gd3+ ions in the UCNPs endow GYT-25% Bi3+ UCNPs with T1-weighted magnetic resonance (MR) imaging capability. PMID- 27696853 TI - Quantitative Proteomic and Phosphoproteomic Comparison of 2D and 3D Colon Cancer Cell Culture Models. AB - Cell cultures are widely used model systems. Some immortalized cell lines can be grown in either two-dimensional (2D) adherent monolayers or in three-dimensional (3D) multicellular aggregates, or spheroids. Here, the quantitative proteome and phosphoproteome of colon carcinoma HT29 cells cultures in 2D monolayers and 3D spheroids were compared with a stable isotope labeling of amino acids (SILAC) labeling strategy. Two biological replicates from each sample were examined, and notable differences in both the proteome and the phosphoproteome were determined by nanoliquid chromatography tandem mass spectrometry (LC-MS/MS) to assess how growth configuration affects molecular expression. A total of 5867 protein groups, including 2523 phosphoprotein groups and 8733 phosphopeptides were identified in the samples. The Gene Ontology analysis revealed enriched GO terms in the 3D samples for RNA binding, nucleic acid binding, enzyme binding, cytoskeletal protein binding, and histone binding for their molecular functions (MF) and in the process of cell cycle, cytoskeleton organization, and DNA metabolic process for the biological process (BP). The KEGG pathway analysis indicated that 3D cultures are enriched for oxidative phosphorylation pathways, metabolic pathways, peroxisome pathways, and biosynthesis of amino acids. In contrast, analysis of the phosphoproteomes indicated that 3D cultures have decreased phosphorylation correlating with slower growth rates and lower cell-to extracellular matrix interactions. In sum, these results provide quantitative assessments of the effects on the proteome and phosphoproteome of culturing cells in 2D versus 3D cell culture configurations. PMID- 27696856 TI - UV-Induced Oxygen Removal for Photostable, High-Efficiency PTB7-Th:PC71BM Photovoltaic Cells. AB - Solution-processed ZnO sol-gel or nanoparticles are widely used as the electron transporting layer (ETL) in optoelectronic devices. However, chemisorbed oxygen on the ZnO layer surface has been shown to be detrimental for the device performance as well as stability. Herein, we demonstrate that chemisorbed oxygen removal based on UV illumination of the ZnO surface layer under a nitrogen atmosphere can, simultaneously, improve the power conversion efficiency and photostability of PTB7-Th:PC71BM-based inverted polymer solar cells. By a systematic study of such a UV illumination procedure, we obtained optimal conditions where both the cell efficiency and stability were improved. We fabricated cells with a power conversion efficiency higher than 9.8% and with a T80 lifetime longer than 500 h, corresponding to about a 2.5-fold enhancement relative to non-UV-treated ZnO reference devices. PMID- 27696857 TI - Noninvasive Ablation of Prostate Cancer Spheroids Using Acoustically-Activated Nanodroplets. AB - We have developed acoustically activated nanodroplets (NDs) using an amphiphilic triblock copolymer, which self-assembles and encapsulates different perfluorocarbons including perfluoropentane (PFP) and perfluorohexane (PFH). Applying histotripsy pulses (i.e., short, high pressure, ultrasound pulses) to solutions of PFP- and PFH-NDs generated bubble clouds at a significantly reduced acoustic pressure compared to the cavitation pressure observed for histotripsy treatment alone. In this report, we summarize the results of combining histotripsy at low frequency (345 and 500 kHz) with PFP-NDs and PFH-NDs on the ablation of PC-3 and C4-2B prostate cancer cells. Using custom built histotripsy transducers coupled to a microscope and a high speed recording camera, we imaged the generation of a cavitation bubble cloud in response to different ultrasound regimes in solution and in tissue-mimicking gel phantoms. We quantified the associated ablation of individual cancer cells and 3D spheroids suspended in solution and embedded in tissue phantoms to compare the ablative capacity of PFP NDs and PFH-NDs. Results show that histotripsy pulses at high acoustic pressure (26.2 MPa) ablated 80% of prostate cancer spheroids embedded in tissue-mimicking gel phantoms. In comparison, combining histotripsy pulses at a dramatically lower acoustic pressure (12.8 MPa) with PFP-NDs and PFH-NDs caused an ablation of 40% and 80% of the tumor spheroid volumes, respectively. These results show the potential of acoustically activated NDs as an image-guided ablative therapy for solid tumors and highlight the higher ablative capacity of PFH-NDs, which correlates with the boiling point of the encapsulated PFH and the stability of the formed bubble cloud.

PMID- 27696858 TI - Improving Efficacy, Oral Bioavailability, and Delivery of Paclitaxel Using Protein-Grafted Solid Lipid Nanoparticles. AB - Oral delivery of anticancer drugs remains challenging despite the most convenient route of drug administration. Hydrophobicity and nonspecific toxicities of anticancer agents are major impediments in the development of oral formulation. In this study, we developed wheat germ agglutinin (WGA)-conjugated, solid lipid nanoparticles to improve the oral delivery of the hydrophobic anticancer drug, paclitaxel (PTX). This study was focused to improve the PTX loading in biocompatible lipid matrix with high bioconjugation efficiency. WGA-conjugated, PTX-loaded solid lipid nanoparticles (LPSN) exhibited enhanced anticancer activity against A549 lung cancer cells after internalization through lectin receptors than free PTX. Biodistribution studies in rats revealed that LPSN significantly improved the oral bioavailability and lung targetability of PTX, which could be due to cumulative bioadhesive property of the nanocarrier system and the targeting ligand WGA. PMID- 27696859 TI - Vacancy-Induced Semiconductor-Insulator-Metal Transitions in Nonstoichiometric Nickel and Tungsten Oxides. AB - Metal-insulator transitions in strongly correlated oxides induced by electrochemical charging have been attributed to formation of vacancy defects. However, the role of native defects in affecting these transitions is not clear. Here, we report a new type of phase transition in p-type, nonstoichiometric nickel oxide involving a semiconductor-to-insulator-to-metal transition along with the complete reversal of conductivity from p- to n-type at room temperature induced by electrochemical charging in a Li+-containing electrolyte. Direct observation of vacancy-ion interactions using in situ near-infrared photoluminescence spectroscopy show that the transition is a result of passivation of native nickel (cationic) vacancy defects and subsequent formation of oxygen (anionic) vacancy defects driven by Li+ insertion into the lattice. Changes in the oxidation states of nickel due to defect interactions probed by X ray photoemission spectroscopy support the above conclusions. In contrast, n type, nonstoichiometric tungsten oxide shows only insulator-to-metal transition, which is a result of oxygen vacancy formation. The defect-property correlations shown here in these model systems can be extended to other oxides.

PMID- 27696855 TI - Determining the Mitochondrial Methyl Proteome in Saccharomyces cerevisiae using Heavy Methyl SILAC. AB - Methylation is a common and abundant post-translational modification. High throughput proteomic investigations have reported many methylation sites from complex mixtures of proteins. The lack of consistency between parallel studies, resulting from both false positives and missed identifications, suggests problems with both over-reporting and under-reporting methylation sites. However, isotope labeling can be used effectively to address the issue of false-positives, and fractionation of proteins can increase the probability of identifying methylation sites in lower abundance. Here we have adapted heavy methyl SILAC to analyze fractions of the budding yeast Saccharomyces cerevisiae under respiratory conditions to allow for the production of mitochondria, an organelle whose proteins are often overlooked in larger methyl proteome studies. We have found 12 methylation sites on 11 mitochondrial proteins as well as an additional 14 methylation sites on 9 proteins that are nonmitochondrial. Of these methylation sites, 20 sites have not been previously reported. This study represents the first characterization of the yeast mitochondrial methyl proteome and the second proteomic investigation of global mitochondrial methylation to date in any organism. PMID- 27696865 TI - Electrochemical Synthesis of Highly Oriented, Transparent, and Pinhole-Free ZnO and Al-Doped ZnO Films and Their Use in Heterojunction Solar Cells. AB - Electrochemical synthesis conditions using nonaqueous solutions were developed to prepare highly transparent (T > 90%) and crystalline ZnO and Al-doped ZnO (AZO) films for use in solar energy conversion devices. A focused effort was made to produce pinhole-free films in a reproducible manner by identifying a key condition to prevent the formation of cracks during deposition. The polycrystalline domains in the resulting films had a uniform orientation (i.e., the c-axis perpendicular to the substrate), which enhanced the electron transport properties of the films. Furthermore, electrochemical Al doping of ZnO using nonaqueous media, which was demonstrated for the first time in this study, effectively increased the carrier density and raised the Fermi level of ZnO. These films were coupled with an electrodeposited p-type Cu2O to construct p-n heterojunction solar cells to demonstrate the utilization of these films for solar energy conversion. The resulting n-ZnO/p-Cu2O and n-AZO/p-Cu2O cells showed excellent performance compared with previously reported n-ZnO/p-Cu2O cells prepared by electrodeposition. In particular, replacing ZnO with AZO resulted in simultaneous enhancements in short circuit current and open circuit potential, and the n-AZO/p-Cu2O cell achieved an average power conversion efficiency (eta) of 0.92 +/- 0.09%. The electrodeposition condition reported here will offer a practical and versatile way to produce ZnO or AZO films, which play key roles in various solar energy conversion devices, with qualities comparable to those prepared by vacuum-based techniques. PMID- 27696864 TI - Probing Grain-Boundary Chemistry and Electronic Structure in Proton-Conducting Oxides by Atom Probe Tomography. AB - A laser-assisted atom-probe-tomographic (LAAPT) method has been developed and applied to measure and characterize the three-dimensional atomic and electronic nanostructure at an yttrium-doped barium zirconate (BaZr0.9Y0.1O3-delta, BZY10) grain boundary. Proton-conducting perovskites, such as BZY10, are attracting intense interest for a variety of energy conversion applications. However, their implementation has been hindered, in part, because of high grain-boundary (GB) resistance that is attributed to a positive GB space-charge layer (SCL). In this study, LAAPT is used to analyze BZY10 GB chemistry in three dimensions with subnanometer resolution. From this analysis, maps of the charge density and electrostatic potential arising at the GBs are derived, revealing for the first time direct chemical evidence that a positive SCL indeed exists at these GBs. These maps reveal new insights on the inhomogeneity of the SCL region and produce an average GB potential barrier of approximately 580 mV, agreeing with previous indirect electrochemical measurements. PMID- 27696863 TI - 64Cu-Labeled Gp2 Domain for PET Imaging of Epidermal Growth Factor Receptor. AB - This purpose of this study is to determine the efficacy of a 45-amino acid Gp2 domain, engineered to bind to epidermal growth factor receptor (EGFR), as a positron emission tomography (PET) probe of EGFR in a xenograft mouse model. The EGFR-targeted Gp2 (Gp2-EGFR) and a nonbinding control were site-specifically labeled with 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) chelator. Binding affinity was tested toward human EGFR and mouse EGFR. Biological activity on downstream EGFR signaling was examined in cell culture. DOTA-Gp2 molecules were labeled with 64Cu and intravenously injected (0.6-2.3 MBq) into mice bearing EGFRhigh (n = 7) and EGFRlow (n = 4) xenografted tumors. PET/computed tomography (CT) images were acquired at 45 min, 2 h, and 24 h. Dynamic PET (25 min) was also acquired. Tomography results were verified with gamma counting of resected tissues. Two-tailed t tests with unequal variances provided statistical comparison. DOTA-Gp2-EGFR bound strongly to human (KD = 7 +/ 5 nM) and murine (KD = 29 +/- 6 nM) EGFR, and nontargeted Gp2 had no detectable binding. Gp2-EGFR did not agonize EGFR nor antagonize EGF-EGFR. 64Cu-Gp2-EGFR tracer effectively localized to EGFRhigh tumors at 45 min (3.2 +/- 0.5%ID/g). High specificity was observed with significantly lower uptake in EGFRlow tumors (0.9 +/- 0.3%ID/g, p < 0.001), high tumor-to-background ratios (11 +/- 6 tumor/muscle, p < 0.001). Nontargeted Gp2 tracer had low uptake in EGFRhigh tumors (0.5 +/- 0.3%ID/g, p < 0.001). Similar data was observed at 2 h, and tumor signal was retained at 24 h (2.9 +/- 0.3%ID/g). An engineered Gp2 PET imaging probe exhibited low background and target-specific EGFRhigh tumor uptake at 45 min, with tumor signal retained at 24 h postinjection, and compared favorably with published EGFR PET probes for alternative protein scaffolds. These beneficial in vivo characteristics, combined with thermal stability, efficient evolution, and small size of the Gp2 domain validate its use as a future class of molecular imaging agents. PMID- 27696866 TI - HSP47 Promotes Glioblastoma Stemlike Cell Survival by Modulating Tumor Microenvironment Extracellular Matrix through TGF-beta Pathway. AB - Grade IV glioblastoma multiforme (GBM) is the most malignant form of gliomas. HSP47, encoded by SERPINH1 gene, is a serpin which serves as a human chaperone protein for collagen. We have shown that HSP47 is significantly overexpressed in GBM and associated with tumor grade. However, the role of HSP47 on GBM progression and stemlike property remains unclear. The stable overexpression of HSP47 in primary GBM cells was established by lentivirus infection. The effects of HSP47 overexpression on tumor growth and the effects of blocking the TGF-beta pathway on tumor regression were investigated by animal study. The expression of HSP47 was examined by real time qRT-PCR and immunohistochemistry. The stemlike property was investigated by sphere formation and CD44 cell population analysis using flow cytometry. We found that overexpression of HSP47 promotes primary glioma cell tumor formation, invasion, angiogenesis, and stemlike properties. The overexpression of HSP47 was correlated and promoted extracellular matrix (ECM) related genes through the TGF-beta pathway in GBM. Blocking TGF-beta pathway overcomes HSP47 induced tumorigenesis and stemness. This study demonstrated that HSP47 promotes GBM stemlike cell survival by modulating tumor microenvironment ECM through TGF-beta pathway. Blocking the TGF-beta pathway provides a promising therapeutic potential for HSP47 overexpressed GBM. PMID- 27696868 TI - Effect of Final Monomer Deposition Steps on Molecular Layer-by-Layer Polyamide Surface Properties. AB - A current challenge to desalination membrane technology is the inability to precisely control the properties of the polyamide selective layer due to the complexity of interfacial polymerization. In this study, we investigate the ability of molecular layer-by-layer (mLbL) assembly, an alternative polyamide fabrication technique, to create polyamide surfaces with tunable chemistry. We explore the influence of terminating monomer, monomer deposition time, monomer size, and the presence of underlying ionizable functional groups on mLbL-derived polyamide surface properties. AFM colloidal probe measurements, contact angle titrations, QCM cesium adsorption experiments, and XPS data show that polyamide films terminated with m-phenylene diamine (MPD) or trimesoyl chloride (TMC) for 20-30 seconds are chemically similar. Increasing terminating monomer deposition time or using a smaller, more reactive monomer results in more distinct colloidal probe adhesive interactions, contact angle titration curves, negative charge densities, and near surface atomic compositions. By optimizing the final monomer deposition steps, both amine-rich and carboxyl-rich polyamide surfaces can be fabricated, which has implications for the application of mLbL assembly to membrane-based desalination.

AB - Because colorectal cancer (CRC) remains a leading cause of cancer mortality worldwide, more accessible screening tests are urgently needed to identify early stage lesions. We hypothesized that highly sensitive, metabolic profile analysis of stool samples will identify metabolites associated with early stage lesions and could serve as a noninvasive screening test. We therefore applied traveling wave ion mobility mass spectrometry (TWIMMS) coupled with ultraperformance liquid chromatography (UPLC) to investigate metabolic aberrations in stool samples in a transgenic model of premalignant polyposis aberrantly expressing the gene encoding the high mobility group A (Hmga1) chromatin remodeling protein. Here, we report for the first time that the fecal metabolome of Hmga1 mice is distinct from that of control mice and includes metabolites previously identified in human CRC. Significant alterations were observed in fatty acid metabolites and metabolites associated with bile acids (hypoxanthine xanthine, taurine) in Hmga1 mice compared to controls. Surprisingly, a marked increase in the levels of distinctive short, arginine-enriched, tetra-peptide fragments was observed in the transgenic mice. Together these findings suggest that specific metabolites are associated with Hmga1-induced polyposis and abnormal proliferation in intestinal epithelium. Although further studies are needed, these data provide a compelling rationale to develop fecal metabolomic analysis as a noninvasive screening tool to detect early precursor lesions to CRC in humans. PMID- 27696869 TI - A Route to Polysubstituted Aziridines from Carbenes and Imines through a Nondiazo Approach. AB - An efficient method for the synthesis of polysubstituted aziridines utilizing enynones and imines is described. This transformation is achieved through the reaction of imines with donor/donor carbene intermediates, which were generated in situ from the cyclization of enynones. Furthermore, the resulted aziridines were good 1,3-dipoles, which could be efficiently trapped by dipolarophiles to give five-membered heterocycles. The obvious advantages of wide substrate scopes, mild reaction conditions, and high atom efficiency make this system highly appealing for construction of polysubstituted aziridines, 2,5-dihydropyroles, and 1,2,4-triazolidines. PMID- 27696870 TI - Ostwald ripening growth mechanism of gold nanotriangles in vesicular template phases. AB - The mechanism of nanotriangle formation in multivesicular vesicles (MMV) is investigated by using time dependent SAXS measurements in combination with UV-vis spectroscopy, light and transmission electron microscopy. In the first time period 6.5 nm sized spherical gold nanoparticles are formed inside of the vesicles, which build up soft nanoparticle aggregates. In situ SAXS experiments show a linear increase of the volume and molar mass of nanotriangles in the second time period. The volume growth rate of the triangles is 16.1 nm3/min and the growth rate in vertical direction only 0.02 nm/min. Therefore, flat nanotriangles with a thickness of 7 nm and diameters of 23 nm are formed. This process can be described by a diffusion-limited Ostwald ripening growth mechanism. TEM micrographs visualize soft coral-like structures with thin nanoplatelets at the periphery of the aggregates, which disaggregate in the third time period into nanotriangles and spherical particles. The 16 times faster growth of nanotriangles in lateral than that in vertical direction is related to the adsorption of symmetry breaking components, i.e., AOT and the polyampholyte PalPhBisCarb, on the {111} facets of the gold nanoplatelets in combination with confinement effects of the vesicular template phase.

PMID- 27696873 TI - Mechanistic Study on Pd/Mono-N-protected Amino Acid Catalyzed Vinyl-Vinyl Coupling Reactions: Reactivity and E/Z Selectivity. AB - A combined mass spectrometric and computational study of the Pd/mono-N-protected amino acid (MPAA)-catalyzed vinyl-vinyl coupling reactions is reported. Computational study reveals that the reaction is initiated by C-H activation of the styrene followed by the insertion of acrylate. This is supported by mass spectrometry. The MPAA ligand facilitates the cross-coupling reaction between monosubstituted alkenes by stabilizing the active palladium catalyst and offering the N-protecting group as a stronger base than acetate. The E/Z selectivity is attributed to the stronger d-pi interaction between the catalyst and the substrate in the transition state leading to E product. PMID- 27696874 TI - Doped Organic Transistors. AB - Organic field-effect transistors hold the promise of enabling low-cost and flexible electronics. Following its success in organic optoelectronics, the organic doping technology is also used increasingly in organic field-effect transistors. Doping not only increases device performance, but it also provides a way to fine-control the transistor behavior, to develop new transistor concepts, and even improve the stability of organic transistors. This Review summarizes the latest progress made in the understanding of the doping technology and its application to organic transistors. It presents the most successful doping models and an overview of the wide variety of materials used as dopants. Further, the influence of doping on charge transport in the most relevant polycrystalline organic semiconductors is reviewed, and a concise overview on the influence of doping on transistor behavior and performance is given. In particular, recent progress in the understanding of contact doping and channel doping is summarized. PMID- 27696876 TI - Virtual Issue in Memory of Ahmed Zewail.

AB - In addressing caffeine toxicity to the producing cells, engineering a transporter that can move caffeine from cytoplasm across cell membrane to extracellular space, thus enhancing caffeine resistance and potentially increasing the yield in yeast are important. An ABC-transporter bfr1 from Schizosaccharomyces pombe was cloned and transformed into S. cerevisiae, resulting in enhancing caffeine resistance. Afterwards, a library of randomly mutagenized bfr1 mutants through error-prone PCR was generated. It was identified one mutant with drastically increased caffeine resistance (15 mg/mL). Sequencing and structural analysis illustrated that many of the mutations occurred at the cytosolic domain. Site directed mutagenesis of these mutations confirmed at least one amino acid that conferred enhancing caffeine resistance in the mutated bfr1. These data demonstrated engineering ABC-transporters can be an efficient way to reduce product toxicity in heterologous systems.

AB - We report the synthesis, spectroscopy, and the DNA binding properties of a biocompatible, water-soluble, polycationic two-photon absorbing anthracenyl derivative (Ant-PIm) specifically designed for biorelated applications. Detailed insights into the Ant-PIm-DNA binding interaction are provided by using several spectroscopic approaches, including UV-vis absorption, circular dichroism (CD), Fourier-transform infrared spectroscopy (FTIR), steady-state, and time-resolved fluorescence techniques. Absorption and fluorescence quantitative data analysis show a strong Ant-PIm-duplex interaction with binding constants of Kf = 4.7 +/- 0.2 * 105 M-1, 7.1 +/- 0.3 * 105 M-1, and 1.0 +/- 0.1 * 106 M-1 at 298, 304, and 310 K, respectively. Spectral changes observed upon DNA binding provide evidence for a complex formation with off-on fluorescence pattern, which can be related to two consecutive binding equilibria. Results of DNA binders displacement and iodide quenching experimental assays unambiguously point to the groove binding mode of Ant-PIm to the DNA-helicate. Thermodynamic and chemical denaturation studies suggest that long-range interactions of hydrophobic nature regulate the association of Ant-PIm with the biopolymer. The ionic strength dependence of the binding constant shows that electrostatic component has an important contribution to the overall Gibbs free energy. FTIR and CD data provide evidence of partial modification of the B-DNA secondary structure, while the increase in the melting temperature clearly indicates the enhancement of the thermal stability of the duplex. Furthermore, the two-photon absorption cross section spectrum determined using the two-photon excited fluorescence (TPEF) technique shows a strong 2PA maximum at 820 nm with a sigma2 > 800 GM, which emphasizes the advantageous combination of biological and optical properties possessed by this positively charged bioprobe. PMID- 27696878 TI - Polyanils and Polyboranils: Synthesis, Optical Properties, and Aggregation Induced Emission. AB - A first series of polyanils were synthesized by a simple condensation between either isomers of phenylenediamine derivatives or 1,3,5-benzenetriamine and 4 (diethylamino)salicylaldehyde, while a second series resulted from the condensation between 4,6-dihydroxyisophthalaldehyde or 2,5 dihydroxyterephthalaldehyde and differently substituted anilines. All these polyanils showed good chelating abilities toward trivalent boron fragments such as BF2 or BPh2 to yield the corresponding boranils. The optical properties of these novel fluorophores have been studied both in solution and in the solid state and show emission wavelengths covering the entire visible spectrum and near infrared (NIR), depending on molecular structure, substitution, and environment. While faintly fluorescent in solution in their molecular state, some polyanils show typical aggregation-induced emission (AIE) behavior upon addition of increasing amounts of water in THF solution, leading to a sizable enhancement of fluorescence intensity.

AB - An Fe(III)-catalyzed efficient dicarbonylation of imidazoheterocycles has been developed through cross-dehydrogenative coupling between imidazoheterocycles and oxoaldehydes under ambient air in high yields. The present protocol is also applicable to indolizines. Imidazopyridine produced bisimidazopyridine with arylaldehyde.

AB - A novel class of O2-(2,4-dinitrophenyl)-1-[N,N-bis(2-substituted ethyl)amino]diazen-1-ium-1,2-diolates 4-6 were designed, synthesized, and biologically evaluated. The most active compound 6 caused significant DNA damage by releasing N,N-bis(2-TsO ethyl)amine and two molecules of nitric oxide (NO) after activation by GST/GSH in cancer cells, being more cytotoxic against three cancer cell lines than a well-known diazeniumdiolate-based anticancer agent JS-K, suggesting that the strategy has potential to extend to other O2-derived diazeniumdiolates to improve anticancer activity. PMID- 27696881 TI - Quantitative Secretome Analysis of Activated Jurkat Cells Using Click Chemistry Based Enrichment of Secreted Glycoproteins. AB - Quantitative secretome analyses are a high-performance tool for the discovery of physiological and pathophysiological changes in cellular processes. However, serum supplements in cell culture media limit secretome analyses, but serum depletion often leads to cell starvation and consequently biased results. To overcome these limiting factors, we investigated a model of T cell activation (Jurkat cells) and performed an approach for the selective enrichment of secreted proteins from conditioned medium utilizing metabolic marking of newly synthesized glycoproteins. Marked glycoproteins were labeled via bioorthogonal click chemistry and isolated by affinity purification. We assessed two labeling compounds conjugated with either biotin or desthiobiotin and the respective secretome fractions. 356 proteins were quantified using the biotin probe and 463 using desthiobiotin. 59 proteins were found differentially abundant (adjusted p value <=0.05, absolute fold change >=1.5) between inactive and activated T cells using the biotin method and 86 using the desthiobiotin approach, with 31 mutual proteins cross-verified by independent experiments. Moreover, we analyzed the cellular proteome of the same model to demonstrate the benefit of secretome analyses and provide comprehensive data sets of both. 336 proteins (61.3%) were quantified exclusively in the secretome. Data are available via ProteomeXchange with identifier PXD004280. PMID- 27696882 TI - Hot Carrier Extraction from Multilayer Graphene. AB - Hot carriers in semiconductor or metal nanostructures are relevant, for instance, to enhance the activity of oxide-supported metal catalysts or to achieve efficient photodetection using ultrathin semiconductor layers. Moreover, rapid collection of photoexcited hot carriers can improve the efficiency of solar cells, with a theoretical maximum of 85%. Because of the long lifetime of secondary excited electrons, graphene is an especially promising two-dimensional material to harness hot carriers for solar-to-electricity conversion. However, the photoresponse of thus far realized graphene photoelectric devices is mainly governed by thermal effects, which yield only a very small photovoltage. Here, we report a Gr-TiOx-Ti heterostructure wherein the photovoltaic effect is predominant. By doping the graphene, the open circuit voltage reaches values up to 0.30 V, 2 orders of magnitude larger than for devices relying upon the thermoelectric effect. The photocurrent turned out to be limited by trap states in the few-nanometer-thick TiOx layer. Our findings represent a first valuable step toward the integration of graphene into third-generation solar cells based upon hot carrier extraction. PMID- 27696883 TI - Ambient-Air Stable Lithiated Anode for Rechargeable Li-Ion Batteries with High Energy Density. AB - An important requirement of battery anodes is the processing step involving the formation of the solid electrolyte interphase (SEI) in the initial cycle, which consumes a significant portion of active lithium ions. This step is more critical in nanostructured anodes with high specific capacity, such as Si and Sn, due to their high surface area and large volume change. Prelithiation presents a viable approach to address such loss. However, the stability of prelithiation reagents is a big issue due to their low potential and high chemical reactivity toward O2 and moisture. Very limited amount of prelithiation agents survive in ambient air. In this research, we describe the development of a trilayer structure of active material/polymer/lithium anode, which is stable in ambient air (10-30% relative humidity) for a period that is sufficient to manufacture anode materials. The polymer layer protects lithium against O2 and moisture, and it is stable in coating active materials. The polymer layer is gradually dissolved in the battery electrolyte, and active materials contact with lithium to form lithiated anode. This trilayer-structure not only renders electrodes stable in ambient air but also leads to uniform lithiation. Moreover, the degree of prelithiation could vary from compensating SEI to fully lithiated anode. With this strategy, we have achieved high initial Coulombic efficiency of 99.7% in graphite anodes, and over 100% in silicon nanoparticles anodes. The cycling performance of lithiated anodes is comparable or better than those not lithiated. We also demonstrate a Li4Ti5O12/lithiated graphite cell with stable cycling performance. The trilayer structure represents a new prelithiation method to enhance performance of Li-ion batteries.

AB - The Kumada-Corriu reaction is a powerful tool for C-C bond formation, but is seldom utilized due to perceived chemoselectivity issues. Herein, we demonstrate that high-yielding couplings can occur in the presence of many electrophilic and heterocyclic functional groups. Our strategy is mechanically based, matching oxidative addition rates with the rate of syringe pump addition of the Grignard reagent. The mechanistic reason for the effectiveness of this strategy is uncovered by continuous-infusion ESI-MS studies.

AB - Health literacy survey was carried out at the end of 2014 in the context of preparation of implementation strategy of the Program Health 2020 in the Czech Republic. The survey was conducted by the National Institute of Public Health with financial support from the Ministry of Health and the Czech WHO office. Sociological survey replicated comparative research conducted in eight EU countries in the first half of this decade. Representative survey in 1037 respondents in the age over 16 years, selected in all regions of the country. The identical methodology as used in the original study was utilized. Health literacy was measured in the areas of health care, disease prevention and health promotion.We found that 59,4 % of respondents showed limited general health literacy; health literacy in health care is proved to be 49.5 % of the population, in the area of disease prevention it was 54.1 % respondents and in health promotion it was even even 64.3 % of respondents. Compared to the other countries surveyed, Czech Republic occupies the eighth, penultimate place. Health literacy is correlated negatively with age and positively with education. We found a strong social gradient of health literacy which rises with social status. Health literacy quite significantly influences the health status and health behaviors.Key words: health literacy, health behaviour, health promotion, social determinants of health.

AB - The objective of this study is to evaluate performance of the health systems in Visegrad countries - the Czech Republic, Hungary, Poland, and Slovakia. For a comparison, Austria and Germany are included, as they represent Western European countries neighbouring with the Visegrad countries. The health system performance is evaluated by six different measures.In spite of the fact, that methodologies, sets of countries, and time periods differ, we observe very similar findings. The Czech Republic has the best performing health system from the Visegrad countries, and Hungary looks like having the worst performing health system. In case of Poland, the indicators based on subjective view of population show worse performance of the health system than the other more objectively oriented indicators. It seems that Polish people view the health system too negatively in comparison with its real performance. If Germany and Austria are included in the comparison, we observe an existing gap between these two Western European countries and Visegrad countries.Key words: health system performance, Visegrad countries, international comparison.

PMID- 27696888 TI - [Alternative healing methods around us]. AB - This article gives information on selected alternative medicine methods (AMM) under conditions of the Czech health care system. They can be defined as contemporaneous diagnostic and therapeutic methods which differ in their theoretical fundaments as well as practices from the evidence based medicine. This definition is controversial because these methods are an intrinsically incompatible aggregate of modalities acting as a placebo above all. We can encounter many "therapeutic" and "examination" methods which are practiced namely by healers without formal medical education, and connected closely with esotericism. A general feature of the alternative methods is a void usage of scientific concepts and theories, e.g. the concept of energy.Motivations of patients and doctors are briefly introduced here. However, AMM is also an ethical problem because the doctor should help the patient with maximum efficiency hence excluding the methods with a questionable, small or negligible efficiency. The opinions how to find the way out from this situation are divergent. It could be a refusal or a very reserved attitude to AMM plus maximisation of the placebo effect enhancing the efficiency of a rational therapy. Furthermore, the methods most spread in the Czech Republic are subjected to elementary critics - the homoeopathy, acupuncture, the so-called "bioresonance" instrumental methods, psychic healing, and also some refused methods in cancer treatment. In our opinion medicine disposes of sufficient knowledge and experience to assess the efficiency of AMM and refuse them in causal therapy, eventually. Their use as a placebo should be carefully considered.Key words: alternative medicine, placebo, homeopathy, acupuncture.

AB - Currently, the cross-border healthcare still represents a marginal part of the Czech healthcare system's performance, though. Compared to the total healthcare expenditures in the Czech Republic that accounted for CZK 299.9 billion in 2014, the costs of the treatment provided to Czech patients abroad constitute mere 0.27%, and the (subsequently refunded) costs of the treatment provided to foreign patients in the Czech Republic 0.24%.Although data on changes in the volume and reimbursements of healthcare due to the Directive 2011/24/EU have not been published yet, we can expect rather evolutionary than revolutionary development of cross-border healthcare volumes. Taking into account all available data, we can conclude that the cross-border healthcare, as specified by the directive currently in force, is important in our conditions above all in relation to our neighbours, i. e. Germany, Austria, Slovakia and Poland.Key words: cross-border healthcare, patient mobility, international reimbursements EU health policy, Directive 2011/24/EU.

AB - Hospital-based HTA (HB-HTA) consists in implementation of assessment activities "in" or "for" hospitals; hence, it covers processes and methods supporting organization and execution of health technology assessment (HTA) at the level of individual hospitals. This process is multidisciplinary, systematic and evidence based.HB-HTA objectives and methods differ from the classic utilization of HTA at the national regulator level. Most experience and information concerning HB-HTA has originated in two large recent projects: activities of the HB-HTA Interest Group of the HTAi international association established in 2006, and the AdHopHTA European research project (20122015).This paper describes four basic organizational models of HB-HTA, their characteristics and utilization in various countries and hospital types. Results of the AdHopHTA project are analyzed, and recommendations for HB-HTA implementation in Czech hospitals are formulated.Key words: hospital-based HTA, medical device, implementation, hospital strategy.

AB - As military and prison chaplains have been active in the military or prison service for many years, nowadays, hospital chaplains have been active in many hospitals in the Czech Republic, too. The work of hospital chaplains, however, still lacks the necessary legislative framework and being embodied in law, which brings some drawbacks. These include primarily non-participation of the ministry of health as a contractual partner in the agreement on spiritual care in health care, the lack of a framework that would arrange the status of chaplains among other health professionals and the related uncertainty regarding career and competency profile of a chaplain.Moreover, the ministry has not set clear rules for the work of chaplains in hospitals, and due to this fact, it has created the space for providing this service also by unqualified persons. This may ultimately have a negative impact on patients. It is therefore the responsibility of the hospital management to arrange that only professional hospital chaplains sent to hospitals on the basis of an agreement between the hospital and the relevant church work there.Key words: hospital chaplain, spiritual assistant, health care system, legislation.

AB - Two new lasiodiplodins (1-2) together with three known analogues, were isolated from a mangrove endophytic fungus, Lasiodiplodia sp. 318#. Their structures were established by spectroscopic techniques (1D- and 2D-NMR, HR-ESI-MS, etc.), and electronic circular dichroism. Cytotoxic activities of compounds 1-5 were evaluated in vitro. Compound 4 was the most potent, with IC50 values of 5.29 MUM against MMQ, 13.05 MUM against GH3. Preliminary structural-activity analysis indicated that the functional group (resorcinol-3-OH) contributed greatly to the binding of Lasiodiplodins to the cytotoxic activities.

AB - Tuber pseudoexcavatum, Tuber sinoaestivum, and Tuber indicum are the 3 most important truffles growing in southeast China; however, their cultivation is still inefficient owing to the lack of understanding regarding the composition and function of the bacterial and fungal communities from the soils around the fruit bodies and the ectomycorrhiza of these truffles. The aim of this study was to disclose the microbial communities in truffle-producing soils in Huidong County, Sichuan, China, by using barcoded pyrosequencing. Approximately 350 000 quality-controlled sequences were obtained and grouped into 14 025 bacterial operational taxonomic units (OTUs) and 4385 fungal OTUs, which included 29 bacterial and 7 fungal phyla, respectively. The bacterial genus Acidobacterium and fungal genera Modicella, Pseudogymnoascus, and Mortierella were significantly more abundant in the control soils than in the truffle-producing soils (P < 0.05), while the bacterial genus Sphingomonas (Alphaproteobacteria) and arbuscular mycorrhizal fungal genus Glomus were significantly enriched in truffle producing soil than in the control (P < 0.05), indicating their different roles within truffle grounds. Notably, some nonfungal organisms detected by 18S rDNA pyrosequencing were of high abundance, among which Cercozoa and Ochrophyta were significantly (P < 0.05) more abundant in truffle soils than in control soils, indicating their interactions with truffles.

AB - Sophora pachycarpa Schrenk ex C.A.Mey. is an annual plant belonging to the family Fabaceae. The cytotoxic activities of methanol-dichloromethane extracts (1:1) of different parts of S. pachycarpa were investigated on DU145 (prostate cancer cell line) and MCF-7 (breast cancer cell line) cell lines. The root extract of S. pachycarpa was the only extract that showed significant cytotoxic activity with IC50 values of 39.88 and 16.49 MUg/mL on DU145 and MCF-7 cell lines, respectively. The root extract was then subjected to RP-HPLC for further fractionations. Among the isolated fractions from root extract, only one of them had remarkable cytotoxic effects with IC50 value of 26.43 on MCF-7 and 7.54 MUg/mL on DU145 cell lines. Further purification led to isolation of a compound with IC50 values of 5.44 and 2.44 MUg/mL on MCF-7 and DU145 cell lines, respectively. Based on 1H NMR and 13C NMR spectra, together with LC-MS, the structure of the purified compound was assigned as the flavonostilbene alopecurone A.

AB - As a treatment for painful vertebral compression fractures (VCFs), vertebral perforation does not require bone cement infusion. Here, we retrospectively assessed the long-term therapeutic effects of vertebroplasty in a comparison with those of vertebral perforation. The subjects were 64 patients who underwent percutaneous vertebroplasty (PVP group) and 67 patients who underwent vertebral perforation (Perforation group) between 2006 and 2011 at Takeda general hospital. We compared the analgesic effects of the treatments and the incidences of new VCFs between the groups at 15 months postsurgery. The pain scores on a visual analog scale 15 months postsurgery were 2.3 +/- 2.0 in the PVP group and 2.1 +/- 1.4 in the Perforation group, a nonsignificant difference (p = .90). The presence of vertebral mobility did not influence the analgesic effect in either group. New VCFs developed at a significantly higher rate in the PVP group (n = 27, 52%) compared to the Perforation group (n = 11, 24%; p = .0017). This difference was even greater within 3 months of the surgery, in 19 PVP patients (38%) and two Perforation patients (3.0%; p < .0001). However, the incidence after 3 months was eight PVP patients and nine Perforation patients, a nonsignificant difference (p = .50). The Kaplan-Meier analysis suggested that the new fractures after surgery in both treatment groups may occur at the same frequency at around 31 months postoperatively. Vertebroplasty is more effective than vertebral perforation in relieving pain early in the course of treatment, but over the long term, no significant difference in pain was seen between the two treatments. The complication of new fractures seen with cement vertebroplasty is only seen after the procedure. PMID- 27696897 TI - Sleeping Beauty transposition: from biology to applications. AB - Sleeping Beauty (SB) is the first synthetic DNA transposon that was shown to be active in a wide variety of species. Here, we review studies from the last two decades addressing both basic biology and applications of this transposon. We discuss how host-transposon interaction modulates transposition at different steps of the transposition reaction. We also discuss how the transposon was translated for gene delivery and gene discovery purposes. We critically review the system in clinical, pre-clinical and non-clinical settings as a non-viral gene delivery tool in comparison with viral technologies. We also discuss emerging SB-based hybrid vectors aimed at combining the attractive safety features of the transposon with effective viral delivery. The success of the SB based technology can be fundamentally attributed to being able to insert fairly randomly into genomic regions that allow stable long-term expression of the delivered transgene cassette. SB has emerged as an efficient and economical toolkit for safe and efficient gene delivery for medical applications.

AB - Cyanobacterial communities on the phyllosphere of 4 plant species inhabiting the endangered Brazilian Atlantic Forest biome were evaluated using cultivation independent molecular approaches. Total genomic DNA was extracted from cells detached from the surface of leaves of Euterpe edulis, Guapira opposita, Garcinia gardneriana, and Merostachys neesii sampled in 2 Brazilian Atlantic Forest locations along an elevational gradient, i.e., lowland and montane forest. The DNA fingerprinting method PCR-DGGE revealed that the cyanobacterial phyllosphere community structures were mainly influenced by the plant species; geographical location of the plant had little effect. The 16S rRNA gene sequences obtained by clone libraries showed a predominance of nitrogen-fixing cyanobacteria of the order Nostocales, even though the majority of retrieved operational taxonomic units (~60% of the sequences) showed similarity only to uncultured cyanobacteria phylotypes. The leaf surface of Guapira opposita had the highest richness and diversity of cyanobacteria, whereas the M. neesii (bamboo) had the largest number of copies of cyanobacterial 16S rRNA gene per cm2 of leaf. This study investigated cyanobacteria diversity and its distribution pattern in Atlantic forest phyllosphere. The results indicated that plant species is the main driver of cyanobacteria community assemblage in the phyllosphere and that these communities are made up of a high diversity of cyanobacterial taxa that need to be discovered. PMID- 27696899 TI - Active Videogaming in Youth with Physical Disability: Gameplay and Enjoyment. AB - OBJECTIVE: For active videogaming (AVG) to be a meaningful, health-enhancing physical activity option for youth with physical disability, factors related to game performance and enjoyment must be understood. The objective was to explore associations between quality of gameplay, controller usage, heart rate (HR), physical function, and enjoyment during AVG play in youth with physical disability. METHODS: Participants (5 girls, 11 boys, mean age 13.8 +/- 2.7 years) played four AVGs on three platforms (Nintendo(r) WiiTM, Sony PlayStation3 Move, and Microsoft Xbox(r) Kinect), across three sessions. Participants' primary means of mobility were manual (n = 13) and power (n = 3) wheelchairs; majority were diagnosed with cerebral palsy or spina bifida. Functional level was assessed using 17 International Classification of Functioning, Disability and Health mobility items. Participants played each AVG for 8 minutes with a 5-minute rest. Quality of gameplay and ability to use controller were recorded on a five-point Likert scale. HR was recorded immediately following each game and participants completed the Physical Activity Enjoyment Scale (PACES). PACES scores were compared across games and correlations were examined among the variables. RESULTS: PACES scores were significantly greater for Wii Punch-Out compared to Xbox Fitness, Sports Rivals, and Zumba, and for PS3 Sports Champions compared to Xbox Zumba. Higher HR was associated with higher quality of gameplay and a higher PACES score. As quality of gameplay increased, the PACES score increased. CONCLUSION: Game performance and exercise intensity were positively correlated with AVG enjoyment in youth with physical disability, specifically mobility impairments. Further research is warranted to examine the capacity of AVG play to be an enjoyable health-enhancing activity for individuals with physical disability.

AB - Stenotrophomonas maltophilia is a global multidrug-resistant human opportunistic pathogen in clinical environments. Stenotrophomonas maltophilia is also ubiquitous in aqueous environments, soil, and plants. Various molecular typing methods have revealed that S. maltophilia exhibits high levels of phenotypic and genotypic diversity. However, information regarding the genomic diversity within S. maltophilia and the corresponding genetic mechanisms resulting in said diversity remain scarce. The genome sequences of 17 S. maltophilia strains were selected to investigate the mechanisms contributing to genetic diversity at the genome level. The core and large pan-genomes of the species were first estimated, resulting in a large, open pan-genome. A species phylogeny was also reconstructed based on 344 orthologous genes with one copy per genome, and the contribution of four evolutionary mechanisms to the species genome diversity was quantified: 15% 35% of the genes showed evidence for recombination, 0%-25% of the genes in one genome were likely gained, 0%-44% of the genes in some genomes were likely lost, and less than 0.3% of the genes in a genome were under positive selection pressures. We observed that, among the four main mechanisms, homologous recombination plays a key role in maintaining diversity in S. maltophilia. In this study, we provide an overview of evolution in S. maltophilia to provide a better understanding of its evolutionary dynamics and its relationship with genome diversity.

AB - PURPOSE: The aim of the present study was to identify problems with communication with persons with aphasia and persons with dementia in a collaborative interview setting with their significant others. In particular, to compare interactional practices used in order to resolve problems caused by specific symptoms. METHOD: Five persons with aphasia and five persons with dementia and their spouses participated in the study. Interviews were carried out couple by couple, and the interviews had a task-oriented character. The interviews were video and audio recorded. All interviews were transcribed. From the transcriptions categorisations according to previous literature were made. RESULT: The results demonstrated that repair sequences were frequent in interaction involving people with aphasia (PWA), and even more so in interaction involving persons with dementia (PWD). In general, it was the PWA/PWD that initiated the repair sequence more often than the spouse, thus keeping the general rule of a preference for self-initiated repair compared to other-initiated repair. CONCLUSION: The active involvement of the conversational partners in trouble solving sequences in interaction with PWA/PWD demonstrated in the present study indicates that the interactional style of the conversational partner to PWA/PWD important. This implies that conversation partner training programmes would be useful both for PWA and for PWD.

RESULTS: Of the population girls, 21% presented with early (<=11 years), 61% with normative (12-13 years) and 19% with late (>=14 years) menarcheal timing; among the SR applicants, 42% presented with early, 46% with normative and 12% with late menarcheal timing (p = 0.003). The odds ratio for SR applicant girls to have early menarcheal timing was 2.7 (95% confidence interval (CI) 1.3, 5.7), controlling for age and family structure. CONCLUSION: Like emotional and behavioural disorders, gender dysphoria in adolescence is associated in girls with early pubertal timing. The finding is discussed in the light of literature related to pubertal maturation and mental health.

AB - To investigate the effects of exposure to an 1800 MHz electromagnetic field on cell death and cell proliferation in the developing brain, postnatal day 7 (P7) and P21 healthy Kunming mice were randomly assigned into the experimental and control groups. The experimental groups were exposed to an 1800 MHz electromagnetic field for 8 h daily for three consecutive days. The thymidine analog 5-bromo-2-deoxyuridine (BrdU) was injected intraperitoneally 1 h before each exposure session, and all animals were sacrificed 24 h after the last exposure. Cell death and proliferation markers were detected by immunohistochemistry in the dentate gyrus of the hippocampus. Electromagnetic exposure has no influence on cell death in the dentate gyrus of the hippocampus in P7 and P21 mice as indicated by active caspase-3 immunostaining and Fluoro Jade labeling. The basal cell proliferation in the hippocampus was higher in P7 than in P21 mice as indicated by the number of cells labeled with BrdU and by immunohistochemical staining for phosphor-histone H3 (PHH3) and brain lipid binding protein (BLBP). Electromagnetic exposure stimulated DNA synthesis in P7 neural stem and progenitor cells, but reduced cell division and the total number of stem cells in the hippocampus as indicated by increased BrdU labeling and reduced PHH3 and BLBP labeling compared to P7 control mice. There were no significant changes in cell proliferation in P21 mice after exposure to the electromagnetic field. These results indicate that interference with stem cell proliferation upon short-term exposure to an 1800 MHz electromagnetic field depends on the developmental stage of the brain.

AB - INTRODUCTION: Voltage-gated Ca2+ channels are the primary route of Ca2+ entry in vascular smooth muscle cells, playing a key role in the regulation of arterial tone and blood pressure. Since the 60's, L-type Ca2+ channel blockers (CCBs) have been widely used for the treatment of hypertension. Areas covered: T-type Ca2+ channels regulate vascular tone in small-resistance vessels and aldosterone secretion, and N-type channels expressed in sympathetic nerve terminals regulate the release of neurotransmitters. We performed a literature search in MEDLINE, PubMed and ClinicalTrials.gov to identify eligible studies published between January 2001 and March 2016 and reviewed the antihypertensive and renoprotective effects of four CCBs with different pharmacological profiles: azelnidipine (L type), cilnidipine (L-/N-type) and benidipine and efonidipine (L-/T-type CCBs). Despite similar blood pressure lowering effects, L/N- and L/T-type CCBs, compared with L-type CCBs, decreased intraglomerular pressure, improved renal hemodynamics and provided a greater decrease in proteinuria even in patients already treated with renin-angiotensin-aldosterone inhibitors. Expert opinion: Dual L/N- and L/T type CCBs may exhibit therapeutic advantages over L-type blockers in hypertensive patients with chronic kidney disease. Because clinical trials supporting these advantages present important biases, further large-scale, long-term comparative trials are needed to confirm that these differences translate into improved clinical outcomes. PMID- 27696905 TI - Association between parent-adolescent communication about sex-related topics and HIV testing, United States. 2006-2013. AB - Adolescents need information about sex-related topics in order to reduce risk behavior and engage in healthy sexual decision-making. Parents have the potential to be an important source of this information. Using the 2006-2010 and 2011-2013 National Survey of Family Growth, we examined associations between parent adolescent communication before age 18 about sex-related topics and HIV testing among respondents aged 18-24 that ever had sexual intercourse (women = 3893; men = 3359). Analyses showed that for both men and women, discussing how to prevent HIV/AIDS and how to use a condom with a parent before age 18 were positively associated with HIV testing. Among women only, discussions about methods of birth control, where to get birth control, and STDs were positively associated with HIV testing. Developing strategies and interventions to facilitate parent-adolescent communication about sex-related topics, particularly HIV prevention and condom use, may be important to increase HIV testing among young women and men. PMID- 27696906 TI - The role of fulvestrant in endometrial cancer. AB - INTRODUCTION: Endometrial cancer is the most common malignancy of the female genital tract in industrialized countries. The traditional treatment of endometrial cancer is based on a surgical approach. In recent years, systemic endocrine therapy has demonstrated good efficacy in recurrent or metastatic setting, delaying progression, ameliorating quality of life and palliating symptoms. Areas covered: Phase I and II studies on selective estrogen receptor down-regulators used for the treatment of endometrial cancer treatment have been reviewed. The pharmacokinetic and pharmacodynamic features of selective receptor down-regulators have been also investigated. Expert opinion: Selective estrogen receptor down-regulators may exhibit clinical efficacy in the treatment of gynecological malignancies due to their pure estrogen receptor antagonist properties. However, up to now data are still limited and some unsolved questions remain. Fulvestrant has poor oral bioavailability and low pharmacodynamic characteristics. Further trials are required to examine new selective estrogen receptor down-regulator agents with better pharmacodynamic and pharmacokinetic profiles. PMID- 27696907 TI - Field calibration of blowfly-derived DNA against traditional methods for assessing mammal diversity in tropical forests. AB - Mammal diversity assessments based on DNA derived from invertebrates have been suggested as alternatives to assessments based on traditional methods; however, no study has field-tested both approaches simultaneously. In Peninsular Malaysia, we calibrated the performance of mammal DNA derived from blowflies (Diptera: Calliphoridae) against traditional methods used to detect species. We first compared five methods (cage trapping, mist netting, hair trapping, scat collection, and blowfly-derived DNA) in a forest reserve with no recent reports of megafauna. Blowfly-derived DNA and mist netting detected the joint highest number of species (n = 6). Only one species was detected by multiple methods. Compared to the other methods, blowfly-derived DNA detected both volant and non volant species. In another forest reserve, rich in megafauna, we calibrated blowfly-derived DNA against camera traps. Blowfly-derived DNA detected more species (n = 11) than camera traps (n = 9), with only one species detected by both methods. The rarefaction curve indicated that blowfly-derived DNA would continue to detect more species with greater sampling effort. With further calibration, blowfly-derived DNA may join the list of traditional field methods. Areas for further investigation include blowfly feeding and dispersal biology, primer biases, and the assembly of a comprehensive and taxonomically-consistent DNA barcode reference library. PMID- 27696909 TI - Generation of Induced Pluripotent Stem Cells with Substitutes for Yamanaka's Four Transcription Factors. AB - Induced pluripotent stem cells (iPSCs) share many characteristics with embryonic stem cells, but lack ethical controversy. They provide vast opportunities for disease modeling, pathogenesis understanding, therapeutic drug development, toxicology, organ synthesis, and treatment of degenerative disease. However, this procedure also has many potential challenges, including a slow generation time, low efficiency, partially reprogrammed colonies, as well as somatic coding mutations in the genome. Pioneered by Shinya Yamanaka's team in 2006, iPSCs were first generated by introducing four transcription factors: Oct 4, Sox 2, Klf 4, and c-Myc (OSKM). Of those factors, Klf 4 and c-Myc are oncogenes, which are potentially a tumor risk. Therefore, to avoid problems such as tumorigenesis and low throughput, one of the key strategies has been to use other methods, including members of the same subgroup of transcription factors, activators or inhibitors of signaling pathways, microRNAs, epigenetic modifiers, or even differentiation-associated factors, to functionally replace the reprogramming transcription factors. In this study, we will mainly focus on the advances in the generation of iPSCs with substitutes for OSKM. The identification and combination of novel proteins or chemicals, particularly small molecules, to induce pluripotency will provide useful tools to discover the molecular mechanisms governing reprogramming and ultimately lead to the development of new iPSC-based therapeutics for future clinical applications. PMID- 27696910 TI - Effect of Sex of Embryo on Developmental Competence, Epigenetic Status, and Gene Expression in Buffalo (Bubalus bubalis) Embryos Produced by Hand-Made Cloning. AB - Buffalo embryos were produced by hand-made cloning using skin fibroblasts from male and female buffaloes (n = 4 each) as donor cells for examining the effect of sex. Although the rate of blastocyst formation (43.8% +/- 1.31% vs. 42.2% +/- 1.22%) was similar, the total cell number (333 +/- 10.4 vs. 270 +/- 10.9) was higher (p < 0.05) whereas the apoptotic index (6.39 +/- 0.25 vs. 8.52 +/- 0.38) was lower (p < 0.05) for male than for female blastocysts. In the blastocysts, the global level of H3K18ac was found to be in the following order: male>female>IVF (in vitro fertilization) blastocysts (p < 0.05). The global level of H3K9me2 was not significantly different between male and female blastocysts and was higher (p < 0.05) compared with that in their IVF counterparts. The relative mRNA abundance of X-chromosome-linked (XIST, HPRT, PGK, and G6PD), apoptosis- (CASPASE3) and pregnancy-related genes (IFN-tau) was significantly higher (p < 0.05) whereas that of DNMT1 was significantly lower (p < 0.05) in female than in male blastocysts; however, in the case of apoptosis- (BCL-XL) and developmental competence-related genes (IGF1R and OCT4), the expression level was similar between the two groups. The gene expression level of OCT4 and IFN-tau but not of IGF1R was significantly lower (p < 0.05) in cloned than in IVF blastocysts. This study demonstrates that the epigenetic status, quality, and expression level of several genes but not the developmental competence are affected by the sex of cloned embryos. PMID- 27696908 TI - Decoding P4-ATPase substrate interactions. AB - Cellular membranes display a diversity of functions that are conferred by the unique composition and organization of their proteins and lipids. One important aspect of lipid organization is the asymmetric distribution of phospholipids (PLs) across the plasma membrane. The unequal distribution of key PLs between the cytofacial and exofacial leaflets of the bilayer creates physical surface tension that can be used to bend the membrane; and like Ca2+, a chemical gradient that can be used to transduce biochemical signals. PL flippases in the type IV P-type ATPase (P4-ATPase) family are the principle transporters used to set and repair this PL gradient and the asymmetric organization of these membranes are encoded by the substrate specificity of these enzymes. Thus, understanding the mechanisms of P4-ATPase substrate specificity will help reveal their role in membrane organization and cell biology. Further, decoding the structural determinants of substrate specificity provides investigators the opportunity to mutationally tune this specificity to explore the role of particular PL substrates in P4-ATPase cellular functions. This work reviews the role of P4-ATPases in membrane biology, presents our current understanding of P4-ATPase substrate specificity, and discusses how these fundamental aspects of P4-ATPase enzymology may be used to enhance our knowledge of cellular membrane biology. PMID- 27696911 TI - Alpha-A-Crystallin Protects Lens Epithelial Cell-Derived iPSC-Like Cells Against Apoptosis Induced by Oxidative Stress. AB - Cataract, the leading cause of blindness worldwide, is caused by the apoptosis of lens epithelial cells (LECs). alphaA-crystallin is a major structural protein of the lens. However, the antiapoptotic function of alphaA-crystallin in lens stem cells remains unclear. In this study, primary LECs were isolated from postnatal 3 5 days of SD rats and transfected by Sendai virus loaded with four factors, OCT3/4, Sox2, c-Myc, and Klf4, to induced pluripotent stem cells (iPSCs). LEC iPSC-like cells were identified by immunofluorescent staining. CryalphaA-specific shRNA lentivirus was used to knockdown alphaA-crystallin in LEC-derived iPSC-like cells, which were treated with tert-Butyl hydroperoxide. The apoptosis of LEC iPSC-like cells was examined by flow cytometry. We reprogrammed LECs and obtained embryonic stem cell-like colonies. LEC-iPSC-like cells with normal karyotype expressed pluripotent markers such as SSEA-4, TRA-1-60, and TRA-1-81. Knockdown of alphaA-crystallin increased the apoptosis of LEC-iPSC-like cells and rendered them less resistant to oxidation stress induced by tert-Butyl hydroperoxide. In conclusion, LECs could be reprogrammed into iPSC-like cells and alphaA crystallins could protect LEC-iPSC-like cells from oxidation stress-induced apoptosis.

AB - A series of novel hexahydrodibenzoxepine and quinazoline derivatives were designed and synthesized starting from dehydroabietylamine. The cytotoxicities of the compounds against L02 and HepG2 cell lines were investigated. Meanwhile, the plasmid DNA (Escherichia coli) cleavage of several heterocyclic derivatives was studied. These compounds exhibit remarkable activities on plasmid DNA pBR322. Our study provides useful information for developing new and more potent antitumor agents. PMID- 27696914 TI - Maternal hepatitis B surface antigen carrier status and its impact on neonatal outcomes: a cohort study of 21 947 singleton newborns in China. AB - OBJECTIVE: To explore the impact of maternal hepatitis B surface antigen (HBsAg) carrier status on neonatal outcomes. METHODS: A retrospective cohort study was conducted using data from medical records database of six hospitals in China. Information on maternal characteristics and selected neonatal outcomes was retrieved for all women who delivered singleton infants between 1 January 2009 and 31 December 2010. RESULTS: A total of 21 947 singleton newborns and their mothers were included. The prevalence of maternal HBsAg positivity was 4.2% (95% confidence interval (CI) 3.9-4.5%). Compared with infants born to HBsAg-negative women, infants born to HBsAg-positive mothers were more than twice more likely to have a malformation before (adjusted odds ratio (aOR) 2.23, 95% CI 1.15-4.30) and at birth (aOR 2.66, 95% CI 1.38-5.14), but were less likely to be macrosomia (aOR 0.67, 95% CI 0.47-0.96). No statistically significant association was found between maternal HBsAg positivity and preterm birth (aOR 1.20, 95% CI 0.95-1.51), low birth weight (aOR 1.24, 95% CI 0.91-1.69), and Apgar scores at 1 min (aOR 0.88, 95% CI 0.49-1.57) and 5 min (aOR 1.84, 95% CI 0.89-3.81). CONCLUSION: Maternal HBsAg positivity may be associated with a higher risk of congenital malformation. PMID- 27696916 TI - Experience of Psychotropic Medication -An Interview Study of Persons with Psychosis. AB - Psychotropic drugs, particularly antipsychotic types, are a cornerstone of the treatment of people with psychosis. Despite numerous studies showing that drug treatment with psychotropic drugs initially alleviates psychiatric symptoms, the proportion of people with mental health problems and symptoms that do not follow doctors' prescriptions, thus exhibiting so-called non-adherence, is considerable. Non-adherence is predominantly seen as a clinical feature and as a patient characteristic that is especially due to patients' poor understanding that they are ill. There is also a widespread notion that non-adherence is of great disadvantage to the patient. This article is based on interviews with 19 persons diagnosed with psychosis. It challenges the notion of patients being either adherent or non-adherent to the doctor's orders. The findings show that persons with psychosis are active agents when it comes to adjusting medication. The interviewees created their own strategies to gain power over treatment with psychotropic drugs. The most common strategies were to adjust the doses or take breaks of varying lengths from the medication. These deviations from prescriptions were important to conceal, not only from their own psychiatrists, but from all psychiatric staff. PMID- 27696915 TI - An mHealth monitoring system for traditional birth attendant-led antenatal risk assessment in rural Guatemala. AB - Limited funding for medical technology, low levels of education and poor infrastructure for delivering and maintaining technology severely limit medical decision support in low- and middle-income countries. Perinatal and maternal mortality is of particular concern with millions dying every year from potentially treatable conditions. Guatemala has one of the worst maternal mortality ratios, the highest incidence of intra-uterine growth restriction (IUGR), and one of the lowest gross national incomes per capita within Latin America. To address the lack of decision support in rural Guatemala, a smartphone based system is proposed including peripheral sensors, such as a handheld Doppler for the identification of foetal compromise. Designed for use by illiterate birth attendants, the system uses pictograms, audio guidance, local and cloud processing, SMS alerts and voice calling. The initial prototype was evaluated on 22 women in highland Guatemala. Results were fed back into the refinement of the system, currently undergoing RCT evaluation. PMID- 27696918 TI - Early Psychological Preventive Intervention For Workplace Violence: A Randomized Controlled Explorative and Comparative Study Between EMDR-Recent Event and Critical Incident Stress Debriefing. AB - This randomized controlled trial study aims to investigate the efficacy of an early psychological intervention called EMDR-RE compared to Critical Incident Stress Debriefing on 60 victims of workplace violence, which were divided into three groups: 'EMDR-RE' (n = 19), 'CISD' (n = 23), and 'delayed EMDR-RE' (n = 18). EMDR-RE and CISD took place 48 hours after the event, whilst third intervention was delayed by an additional 48 hours. Results showed that after 3 months PCLS and SUDS scores were significantly lower with EMDR-RE and delayed EMDR-RE compared to CISD. After 48 hours and 3 months, none of the EMDR-RE treated victims showed PTSD symptoms. PMID- 27696919 TI - Corrigendum. PMID- 27696917 TI - Lower serotonin level and higher rate of fibromyalgia syndrome with advancing pregnancy. AB - OBJECTIVE: The aim of the study is to investigate the relationship between changes in serotonin levels during pregnancy and fibromyalgia syndrome (FS) and the relationships between FS and the physical/psychological state, biochemical and hormonal parameters, which may be related to the musculoskeletal system. STUDY DESIGN: This study is a prospective case-control study conducted with 277 pregnant women at the obstetric unit of Ankara University Faculty of Medicine, in the period between January and June 2015. FS was determined based on the presence or absence of the 2010 ACR diagnostic criteria and all the volunteers were asked to answer the questionnaires as Fibromyalgia Impact Criteria (FIQ), Widespread Pain Index (WPI), Symptom Severity Scale (SS), Beck Depression Inventory and Visual Analog Scale (VAS). Biochemical and hormonal markers (glucose, TSH, T4, Ca (calcium), P (phosphate), PTH (parathyroid hormone) and serotonin levels) relating to muscle and bone metabolism were measured. RESULTS: In the presence of fibromyalgia, the physical and psychological parameters are negatively affected (p < 0.001). There was no significant difference between the fibromyalgia and control groups in terms of glucose, Ca (calcium), P (phosphorus), PTH (parathyroid hormone), TSH (thyroid stimulant hormone), fT4 (free T4) levels (p = 0.060, 0.799, 0.074, 0.104, 0.797, 0.929, respectively). A reduction in serotonin levels may contribute to the development of fibromyalgia but this was not statistically significant. The Beck Depression Inventory scale statistically showed that increasing scores also increase the risk of fibromyalgia (p <0.001). CONCLUSION: Our study has shown that serotonin levels in women with FS are lower than the control group and that serotonin levels reduce as pregnancy progresses. Anxiety and depression in pregnant women with FS are higher than the control group. The presence of depression increases the likelihood of developing FS at a statistically significant level. Serotonin impairment also increases the chance of developing FS, but this correlation has not been shown to be statistically significant. PMID- 27696920 TI - Stress distribution on short implants with different designs: a photoelastic analysis. AB - Short dental implants have been used as an attempt to avoid bone grafts surgery, however there are few literature reports that evaluate changes to their design. Therefore, the aim of this study was to assess the effect of different short implant design on stress distribution through photoelastic analysis. Six external hexagon (5 * 5 mm) short dental implants with different design were used. Each group was treated with a single crown and a three element fixed partial dental prosthesis, resulting in a total of 12 photoelastic models. The assembling photoelastic model-implant-prosthesis was set in a circular polariscope where loads of 100N were applied on the occlusal surface with a Universal Test Machine (UTM). The tension fringes were photographed and later assessed qualitatively by a graphic software (Adobe Photoshop). Less high-intensity fringes were observed on the short implants with triangular threads, short external hexagon and flat apical profile. In conclusion, the macrodesign influenced the amount of stress distributed to the bone when short dental implants are placed. PMID- 27696921 TI - Prenatal identification of CHD murmur using four segment phonocardiographic signal analysis. AB - Congenital heart defects (CHD) are one of the utmost birth defects present in the neonatal after birth and a big challenge for the researchers to identify the structural abnormality during the antepartum period. An algorithm is presented here to identify the presence of CHD through foetal phonocardiographic (fPCG) signals. The recorded fPCG is decomposed using Daubechies4 wavelet with sub-level threshold to remove the noise in the signal. The Shannon energy is used to identify the different peaks of signals and then S1 and S2 according to the intervals between adjacent peaks. The signal is segmented into four important parts: S1, S1S2, S2 and S2S1. The FFT is used to identify the frequency component present in four segments which in turn indicates the presence of pathological murmur that may turn into CHD. The algorithm is tested on 25 samples with accuracy rate 88% in identifying the presence of a murmur. PMID- 27696922 TI - Evaluation of an in vitro screening model to assess phosgene inhalation injury. AB - Therapeutic development against exposure to toxic gases is hindered by the lack of appropriate models to evaluate candidate compounds prior to animal efficacy studies. In this study, an in vitro, air-liquid interface exposure model has been tested to examine its potential application for screening treatments for phosgene (carbonyl chloride)-induced pulmonary injury. Epithelial cultures on Transwell(r) inserts, combined with a Vitrocell(r) exposure apparatus, provided a physiologically relevant exposure environment. Differentiated human bronchial epithelial (16HBE) cultures were exposed for 8 min to phosgene ranging from 0 to 64 ppm and assessed for changes in transepithelial electrical resistance (TEER, epithelial barrier integrity), cellular viability (XTT) and post-exposure (PE) cellular metabolic energy status. Exposure to phosgene concentrations >=8 ppm caused dose-dependent and significant decreases in TEER and XTT which did not recover within 24-h PE. In addition, at 64 ppm the rate of oxidative glutamine metabolism was significantly inhibited at 6 and 24 h after exposure. Glycolytic activities (glucose utilization and lactate production) were also inhibited, but to a lesser extent. Decreased glycolytic function can translate to insufficient energy sources to counteract barrier function failure. Consistent and sensitive markers of phosgene exposure were TEER, cell viability and decreased metabolism. As such, we have assessed an appropriate in vitro model of phosgene inhalation that produced quantifiable alterations in markers of lung cell metabolism and injury in human airway epithelial cells. Data indicate the suitability of this model for testing classes of anti-edemagenic compounds such as corticosteroids or phosphodiesterase inhibitors for evaluating phosgene therapeutics. PMID- 27696923 TI - Repeated restraint stress produces acute and chronic changes in hemodynamic parameters in rats. AB - Noninvasive hemodynamic measurements in rats require placing animals in restrainers. To minimize restraint stress-induced artifacts several habituation protocols have been proposed, however, the results are inconclusive. Here, we evaluated if a four-week habituation is superior to a shorter habituation, or no habituation. This is the first study comparing different habituation protocols with the use of four-week continuous telemetry measurements. We did the experiments on male, 16-week old, Sprague-Dawley rats. Continuous recordings of mean arterial blood pressure (MABP) and heart rate (HR) were made before and during habituation protocols. Rats were subjected either to control (four weeks of restraint-free recordings, n = 5) or two-week (seven restraints, n = 6) or four-week (14 restraints, n = 6) restraint sessions. The restraint protocols included placement of rats in the middle of the dark phase into plastic restrainers as used for tail-cuff measurements. Restraint lasted for 60 min, and was repeated every second day. Each restraint significantly increased MABP (by 15 25 mmHg) and HR (by 40-120 beats/min). Exposure to the restraint protocols decreased diurnal variation in MABP. There was no hemodynamic adaptation to repeated restraint, and no significant difference in hemodynamic response to restraint among controls, the two-week and the four-week groups. In conclusion, our study indicates that measurements in restrained rats are not likely being made without stress-induced changes in MABP. Moreover, in hemodynamic studies in repeatedly restrained rats longer habituation is not superior to shorter habituation. PMID- 27696925 TI - Corrigendum. PMID- 27696924 TI - The RNA-editing deaminase ADAR is involved in stress resistance of Artemia diapause embryos. AB - The most widespread type of RNA editing, conversion of adenosine to inosine (A >I), is catalyzed by two members of the adenosine deaminase acting on RNA (ADAR) family, ADAR1 and ADAR2. These enzymes edit transcripts for neurotransmitter receptors and ion channels during adaption to changes in the physical environment. In the primitive crustacean Artemia, when maternal adults are exposed to unfavorable conditions, they release diapause embryos to withstand harsh environments. The aim of the current study was therefore to elucidate the role of ADAR of Artemia diapause embryos in resistance to stress. Here, we identified Artemia ADAR (Ar-ADAR), which harbors a putative nuclear localization sequence (NLS) and two double-stranded RNA-binding motifs (dsRBMs) in the amino terminal region and an adenosine deaminase (AD) domain in the carboxyl-terminal region. Western blot and immunofluorescence analysis revealed that Ar-ADAR is expressed abundantly in post-diapause embryos. Artemia (n = 200, three replicates) were tested under basal and stress conditions. We found that Ar-ADAR was significantly induced in response to the stresses of salinity and heat-shock. Furthermore, in vivo knockdown of Ar-ADAR (n = 100, three replicates) by RNA interference induced formation of pseudo-diapause embryos, which lack resistance to the stresses and exhibit high levels of apoptosis. These results indicate that Ar-ADAR contributes to resistance to stress in Artemia diapause embryos. PMID- 27696926 TI - Development of a new miniaturized bioreactor for axon stretch growth. AB - Peripheral nerve injury requires a physical bridge across the lesion, which is limited by the insufficient supply of donor nerves. Here, we developed a new miniaturized bioreactor system for axon stretch growth. Dorsal root ganglia explants were first placed on two adjoining substrates and formed new synaptic connections. The axon bundles across the border between the top and bottom membranes were then stretched in a stepwise fashion by a microstepper motor system. After several days of stretch, the axon tracts could reach lengths that could develop into living nervous tissue constructs. In order to achieve appropriate neuronal culture to stimulate physiological conditions during axon stretch, we tested a variety of coating methods. Based on these results, the elongator substrates were coated with both poly-D-lysine and rat-tail collagen to maximize the number of axon bundles. Additionally, we found that increasing the axon stretch by 1[Formula: see text][Formula: see text]m at each step resulted in the highest stability. The bridging axons adapted to the stretch by increasing their length from 500[Formula: see text][Formula: see text]m to 5.94[Formula: see text]mm over 7 days of stretch growth. Immunocytochemical analysis confirmed that beta-III-tubulin, a major cytoskeletal constituent and neuronal marker, was present along axons. The findings demonstrate that bioreactor has the potential to generate transplant materials to address neural repair. PMID- 27696927 TI - Classification of the fragrant styles and evaluation of the aromatic quality of flue-cured tobacco leaves by machine-learning methods. AB - During commercial transactions, the quality of flue-cured tobacco leaves must be characterized efficiently, and the evaluation system should be easily transferable across different traders. However, there are over 3000 chemical compounds in flue-cured tobacco leaves; thus, it is impossible to evaluate the quality of flue-cured tobacco leaves using all the chemical compounds. In this paper, we used Support Vector Machine (SVM) algorithm together with 22 chemical compounds selected by ReliefF-Particle Swarm Optimization (R-PSO) to classify the fragrant style of flue-cured tobacco leaves, where the Accuracy (ACC) and Matthews Correlation Coefficient (MCC) were 90.95% and 0.80, respectively. SVM algorithm combined with 19 chemical compounds selected by R-PSO achieved the best assessment performance of the aromatic quality of tobacco leaves, where the PCC and MSE were 0.594 and 0.263, respectively. Finally, we constructed two online tools to classify the fragrant style and evaluate the aromatic quality of flue cured tobacco leaf samples.

PMID- 27696929 TI - Effects of Psychoeducation Given to Caregivers of People With a Diagnosis of Schizophrenia. AB - The aim of this study was to evaluate the effectiveness of psychoeducation given to caregivers of patients diagnosed with schizophrenia on their perceptions of burden and on clinical course of patients. This was a quasi-experimental study with pre-post tests and a control group and designed as a nonrandomized controlled intervention trial. While the patients in both the intervention and the control group received treatment as usual (TAU), only the caregivers in the study group were offered two sessions of psychoeducation a week for one month, with a total of eight sessions. Effectiveness of the psychoeducation given was evaluated by comparing scores of Perceived Family Burden Scale (PFBS) and Positive and Negative Syndrome Scale (PANSS) obtained before and three months after delivery between the intervention and the control groups. Mean PFBS burden scores of the control group at baseline and follow-up were 45.7 and 44.5, respectively. Mean PFBS burden scores of the intervention group were 45.2 at baseline and 38.6 at follow-up. Analysis of variance revealed significant and medium to large size interaction effects of time and group factors on total burden scores of family members (F1.58 = 5.59; p < 0.05; etap2 = 0.09) and on total PANSS scores of patients (F1.58 = 104.78; p < 0.001; etap2 = 0.64). Our findings suggest that psychoeducation offered to the caregivers along with TAU offered to patients might result in diminished perceptions of burden among caregivers and enhanced improvement in the clinical course of patients as a result of psychoeducation offered to caregivers. PMID- 27696930 TI - Dopamine DRD2 polymorphism (DRD2/ANNK1-Taq1A) is not a significant risk factor in writer's cramp. AB - Writers' cramp is a movement disorder with dystonic co-contraction of fingers and hand during writing and is part of the clinical spectrum of focal dystonias. Previous studies showed reduced striatal dopamine receptor D2 (DRD2) availability in dystonia. The expression of D2 receptors is modulated by a DRD2/ANKK1-Taq1A polymorphism (rs1800497). This study addresses the question of whether the DRD2/ANKK1-Taq1A polymorphism is a risk factor for writer's cramp. We determined the DRD2/ANKK1-Taq1A polymorphism 34 patients with writer's cramp compared to 67 age matched controls. 35.3% of the patients and 31.3% of our controls were assigned to the A1 genotype status (p = .7). Therefore DRD2/ANKK1-Taq1A gene is not a significant risk factor in the evolution of writer's cramp. PMID- 27696931 TI - Targeting the vasculature: anti-angiogenic agents for malignant mesothelioma. AB - INTRODUCTION: Malignant mesothelioma (MM) is an aggressive malignancy of the pleura and other serosal membranes originating from mesothelial cells that, despite decades of research, continues to have limited therapeutic options and is associated with a poor prognosis. Areas covered: MMs induce a strong inflammatory response that is also associated with neoangiogenesis and activation of proangiogenic factors. Given this, several anti-angiogenic agents have been trialled in a variety of malignancies including mesothelioma. Herein we summarise the role of angiogenesis in MM and the current available data targeting these pathways. Expert commentary: The addition of bevacizumab to cisplatin/pemetrexed chemotherapy is currently a therapeutic option with a proven 2.7 month overall survival benefit in fit patients less than 75. Other antiangiogenics such as nintedinib show early promise, although the Phase III trial results are eagerly awaited before this therapy enters treatment paradigms. Beyond this, it is likely that combinations of antiangiogenics with immunotherapies will be investigated in future studies. PMID- 27696932 TI - Improving diagnostic molecular tests to monitor urothelial carcinoma recurrence. AB - INTRODUCTION: The high recurrence rates associated with non-muscle invasive bladder cancer require close surveillance with cystoscopy, an invasive and expensive procedure with risk of missing cancer. Finding an accurate urinary biomarker that can detect recurrent disease would represent a significant advancement in management. Areas covered: This review summarizes the commercially available urinary biomarkers including cytology, UroVysion, BTA, NMP22, uCyt+, and Cxbladder assays. Additionally, we review recent investigational urinary biomarkers that hold promise in bladder cancer surveillance. Expert commentary: The quest for a reliable urinary biomarker for bladder cancer is decades-old and seems intuitive given the direct contact of urine with malignant urothelium. Beyond urine cytology, there are many commercially-available products approved for surveillance. However, none of the assays are routinely used due to lack of sensitivity and/or specificity. As such, emerging technologies, in particular the '-omic' technologies have resulted in a proliferation of promising reports on novel biomarkers in recent literature. PMID- 27696933 TI - High-flavanol and high-theobromine versus low-flavanol and low-theobromine chocolate to improve uterine artery pulsatility index: a double blind randomized clinical trial. AB - OBJECTIVE: To evaluate the impact of high-flavanol and high-theobromine (HFHT) chocolate in women at risk of preeclampsia (PE). STUDY DESIGN: We conducted a single-center randomized controlled trial including women with singleton pregnancy between 11 and 14 weeks gestation who had bilateral abnormal uterine artery (UtA) waveforms (notching) and elevated pulsatility index (PI). Participants were randomized to either HFHT or low-flavanol and low-theobromine (LFLT) chocolate (30 grams daily for a total of 12 weeks). UtA PI, reported as multiple of medians (MoM) adjusted for gestational age, was assessed at baseline and 12 weeks after randomization. RESULTS: One hundred thirty-one women were randomized with mean gestational age of 12.4 +/- 0.6 weeks and a mean UtA PI of 1.39 +/- 0.31 MoM. UtA PI adjusted for gestational age significantly decreased from baseline to the second visit (12 weeks later) in the two groups (p < 0.0001) but no significant difference was observed between the groups (p = 0.16). CONCLUSIONS: Compared with LFLT chocolate, daily intake of HFHT chocolate was not associated with significant changes of UtA PI. Nevertheless, the improvement observed in both groups suggests that chocolate could improve placental function independently of flavanol and/or theobromine content. PMID- 27696934 TI - Effects of Vegetable Oils with Different Fatty Acid Compositions on Cognition and Memory Ability in Abeta25-35-Induced Alzheimer's Disease Mouse Model. AB - In this study, we aimed to investigate the protective effect of three kinds of vegetable oils with different fatty acid compositions against cognitive impairment in an Alzheimer's disease (AD) mouse model. After intracerebroventricular injection of amyloid beta25-35 (Abeta25-35) into the brain of institute of cancer research mice, olive oil (rich in oleic acid, C18:1), corn oil (rich in linoleic acid, C18:2), and perilla oil (rich in alpha linolenic acid [ALA], C18:3) were administered at the oral dose of 500 mg/kg/day for 14 days. The results revealed that Abeta25-35 induced learning and memory dysfunction according to the T-maze, novel object recognition, and Morris water maze tests. Among the three vegetable oils, however, the perilla oil group of mice showed marked attenuation of cognitive impairment, that is, a greater number of explorations on a new route/object than on an old route/object in the T-maze and novel object recognition tests. In the Morris water maze test, perilla oil decreased the time to reach the platform and increased the number of crossings over the target quadrant in which the platform was located previously. Furthermore, the beneficial effect of perilla oil supplementation on oxidative stress was reflected in the inhibition of malondialdehyde and nitric oxide (NO) production in Abeta25-35-injected mice. We also found that perilla oil downregulated protein expression levels of inducible NO synthase and cyclooxygenase-2 and upregulated brain-derived neurotrophic factor. These findings showed that ALA-rich perilla oil has a potential for prevention or treatment of neurodegenerative diseases such as AD. PMID- 27696936 TI - Context-specific adjustment of cognitive control: Transfer of adaptive control sets. AB - Cognitive control protects processing of relevant information from interference by irrelevant information. The level of this processing selectivity can be flexibly adjusted to different control demands (e.g., frequency of conflict) associated with a certain context, leading to the formation of specific context control associations. In the present study we investigated the robustness and transferability of the acquired context-control demands to new situations. In three experiments, we used a version of the context-specific proportion congruence (CSPC) paradigm, in which each context (e.g., location) is associated with a specific conflict frequency, determining high and low control demands. In a learning phase, associations between context and control demands were established. In a subsequent transfer block, stimulus-response mappings, whole task sets, or context-control demands changed. Results showed an impressive robustness of context-control associations, as context-specific adjustments of control from the learning phase were virtually unaffected by new stimuli and tasks in the transfer block. Only a change of the context-control demand eliminated the context-specific adjustment of control. These findings suggest that context-control associations that have proven to be adaptive in the past are continuously applied despite major changes in the task structure as long as the context-control associations remain the same. PMID- 27696938 TI - A novel modelling and simulation method of hip joint surface contact stress. AB - Understanding the hip joint surface contact stress distribution characteristics is helpful to determine hip joint biomechanical features and abnormal pathological behavior. Firstly, a 3-dimensional static hip joint biomechanical model is built using analytical method of model in order to study biomechanical properties including bearing area, stress distribution and the peak value of the contact stress of the femoral head, which reveals the relationship between the biomechanical properties and its geometric parameters. Secondly, based on the finite element analysis of the hip joint model, the contact stress distribution on the surface of femoral head is acquired under the condition of the different joint force and the acetabulum coverage rate. Finally, according to the evaluation of the femoral head surface stress and contact stress peak under different load distribution, accuracy and universality of the biomechanical model is verified.

AB - G-quadruplexes are non-canonical DNA secondary structures involved in several genomic and molecular processes.

We also discuss alternative strategies for specifically interfering G-quadruplex in vivo. PMID- 27696935 TI - The evolution of recombinant thrombolytics: Current status and future directions. AB - Cardiovascular disorders are on the rise worldwide due to alcohol abuse, obesity, hypertension, raised blood lipids, diabetes and age-related risks. The use of classical antiplatelet and anticoagulant therapies combined with surgical intervention helped to clear blood clots during the inceptive years. However, the discovery of streptokinase and urokinase ushered the way of using these enzymes as thrombolytic agents to degrade the fibrin network with an issue of systemic hemorrhage. The development of second generation plasminogen activators like anistreplase and tissue plasminogen activator partially controlled this problem. The third generation molecules, majorly t-PA variants, showed desirable properties of improved stability, safety and efficacy with enhanced fibrin specificity. Plasmin variants are produced as direct fibrinolytic agents as a futuristic approach with targeted delivery of these drugs using liposome technlogy. The novel molecules from microbial, plant and animal origin present the future of direct thrombolytics due to their safety and ease of administration. PMID- 27696939 TI - Are Dietary Patterns Associated with Depression in U.S. Adults? AB - Nutrition is one of the most important modifiable determinants for and consequences of both mental and physical heath. Depression has become an increasingly important public health issue. We tested whether dietary patterns derived from food group intake are associated with depression in U.S. adults in a cross-sectional study with national population. This study included 4180 men and 4196 women aged 20-79 years in the 2007-2010 National Health and Nutrition Examination Surveys (NHANES), with complete data of one 24-h dietary recall, sociodemographics, lifestyles, and Patient Health Questionnaires (PHQ-9) for screening depression. Two major dietary patterns identified by factor analysis were investigated for their associations with presence of depression (PHQ-9 score >=10) by using linear and multivariate logistic regressions. One of two major patterns, labeled "Western" dietary pattern was characterized by high intakes of nonwhole grain, white potatoes, cheese, meat, discretionary oil and fat, and added sugar; the second dietary pattern that was labeled "Healthy" dietary pattern was characterized by high intakes of whole grains, vegetables, fruits, fish, nuts and seeds. The "Western" dietary pattern was not significantly associated with depression in both men and women. The "Healthy" dietary pattern scores were inversely associated with the PHQ-9 depression scores and odd ratios (ORs) of depression after adjustment for covariates in women but not in men. The OR of depression in women with the highest quintile of "Healthy" dietary pattern scores was 0.60 (95% confidence interval [CI]: 0.42-0.85, P < .001) compared to the lowest quintile as a reference. These findings warrant future interventions or clinical trials in elucidating causal and effect relations of depression and dietary patterns, an important public health concern. PMID- 27696950 TI - The beat of social cognition: Exploring the role of heart rate variability as marker of mentalizing abilities. AB - There is a long-standing debate on the influence of physiological signals on social behavior. Recent studies suggested that heart rate variability (HRV) may be a marker of social cognitive processes. However, this evidence is preliminary and limited to laboratory studies. In this study, 25 participants were assessed with a social cognition battery and asked to wear a wearable device measuring HRV for 6 consecutive days. The results showed that reduced HRV correlated with higher hostility attribution bias. However, no relationship was found between HRV and other social cognitive measures including facial emotion recognition, theory of mind or emotional intelligence. These results suggest that HRV may be linked to specific social cognitive processes requiring online emotional processing, in particular those related to social threat. These findings are discussed in the context of the neurovisceral integration model. PMID- 27696955 TI - Interventions to reduce intimate partner violence perpetration among people with substance use disorders. AB - The social and economic cost of intimate partner violence (IPV) is exorbitant and highlights the need for policy reform as it pertains to IPV interventions at a global level. There are multiple variables associated with the aetiology of IPV and, hence, multiple treatment needs must be considered. Substance use is one of several factors likely to influence the occurrence of IPV, but often goes unaddressed in standard treatment approaches. This review will discuss several treatment models for substance using offenders of IPV, including Psycho educational Models, Cognitive Behavioural Therapy, Couples' Treatments, Parenting Programmes, Integration of Care Models, and Pharmacotherapies. Clinical recommendations will be discussed. Treatment outcomes among substance using offenders of IPV may be improved by implementing changes in protocol that increase diagnostic evaluations, integrate care with evidence-based models, require limits to the number of offenders in a group, and require qualifications for clinicians who treat offenders (licensed and trained psychologists, social workers, and/or psychiatrists).

AB - The effects of Canavalia gladiata ethanolic extract on endurance swimming capacity were evaluated in a mouse model. The mice were orally administered distilled water (CON), hot water extract (CGW), or 80% ethanol extract (CGE). The swimming time to exhaustion was significantly prolonged in the CGE group. Of the three groups, the CGE showed the lowest blood lactate and the highest nonesterified fatty acid and muscle glycogen levels. These results suggest that the administration of CGE could improve endurance swimming capacity by enhancing lipid catabolism and thereby preserving glycogen stores. PMID- 27696958 TI - Function and application of a non-ester-hydrolyzing carboxylesterase discovered in tulip. AB - Plants have evolved secondary metabolite biosynthetic pathways of immense rich diversity. The genes encoding enzymes for secondary metabolite biosynthesis have evolved through gene duplication followed by neofunctionalization, thereby generating functional diversity. Emerging evidence demonstrates that some of those enzymes catalyze reactions entirely different from those usually catalyzed by other members of the same family; e.g. transacylation catalyzed by an enzyme similar to a hydrolytic enzyme. Tuliposide-converting enzyme (TCE), which we recently discovered from tulip, catalyzes the conversion of major defensive secondary metabolites, tuliposides, to antimicrobial tulipalins. The TCEs belong to the carboxylesterase family in the alpha/beta-hydrolase fold superfamily, and specifically catalyze intramolecular transesterification, but not hydrolysis. This non-ester-hydrolyzing carboxylesterase is an example of an enzyme showing catalytic properties that are unpredictable from its primary structure. This review describes the biochemical and physiological aspects of tulipalin biogenesis, and the diverse functions of plant carboxylesterases in the alpha/beta-hydrolase fold superfamily. PMID- 27696959 TI - Antioxidant activity of commercial food grade tannins exemplified in a wine model. AB - Although commercial tannins are widely used in foods and beverages, an improved understanding of the structure and composition of vegetable tannins is needed to promote the exploitation of agri-food by-products and waste and their valorisation in more sustainable industrial applications. This study aims to characterise the phytochemical composition and antioxidant activity of 13 food grade tannins using multiple analytical approaches, including spectrophotometry and HPLC-ECD to determine the amount of targeted polyphenolic compounds. Moreover, the antioxidant activity of tannins was assessed in terms of radical scavenging activity (DPPH* assay), reducing power (FRAP assay), and redox properties (cyclic voltammetry, CV). A statistical univariate and multivariate correlation analysis was performed on 17 parameters including tannin content (range: 0.71-1.62 mM), gallic acid, (+)-catechin, syringic acid and (-) epicatechin. The compositional profile of tannins was related to their chemical moiety, antioxidant activity and the botanical origin of the extracts. In particular, the CV signal at 500 mV was highly correlated with DPPH* value due to the catechol ring of flavonoids and trigalloyl moieties of gallic acid-based compounds. Practical examples of tannins application in winemaking are discussed. PMID- 27696963 TI - Rare extraskeletal Ewing's sarcoma mimicking as adenocarcinoma of the sigmoid. AB - INTRODUCTION: Extraskeletal Ewing's sarcoma (EES) is a rare finding in comparison with Ewing's sarcoma of bone and usually manifests in young patients. However, even in older patients, one must consider the diagnosis. PATIENTS AND METHODS: In this case, we describe a 52-year-old woman diagnosed with EES, mimicking as adenocarcinoma of the sigmoid. RESULTS: The tumor was not visualized by a multi slice spiral computed tomography of the abdomen and pelvis with intravenous contrast, and eventually the diagnosis was made by positive immunohistochemical staining for CD99 and by molecular testing for EWSR1 translocation. CONCLUSIONS: This combination of the patient's age and the localization of the tumor mimicking an adenocarcinoma of the sigmoid has never been described before.

AB - We investigated the efficacy of supplementing the diet with choline or betaine in ameliorating lipid accumulation induced by vitamin B6 (B6) deficiency in rat liver. Male Wistar rats were fed a control, B6-deficient, choline-supplemented (2, 4, or 6 g choline bitartrate/kg diet) B6-deficient diet or betaine supplemented (1, 2, or 4 g betaine anhydrous/kg diet) B6-deficient diet for 35 d; all diets contained 9 g L-methionine (Met)/kg diet. Choline or betaine supplementation attenuated liver lipid deposition and restored plasma lipid profiles to control levels. These treatments restored the disruptions in Met metabolism and the phosphatidylcholine (PC)/phosphatidylethanolamine (PE) ratio induced by B6 deficiency in liver microsomes. These results suggest that choline and betaine ameliorated liver lipid accumulation induced by B6 deficiency via recovery of Met metabolism and very low-density lipoprotein secretion by restoring the supply of PC derived from PE. PMID- 27696972 TI - Cefepime loaded O-carboxymethyl chitosan microspheres with sustained bactericidal activity and enhanced biocompatibility. AB - Cefepime (CFP) is a frequently used antibiotic for prevention of post-surgery infection. Systemic delivery of CFP in a bulk dose usually shows effective therapeutic effects, while cytotoxicity can also be generated. To avoid the drawback of systemic delivery of antibiotic, local and controlled administration of drug is being employed to prolong therapeutic effects and reduce cytotoxicity by sustaining drug release and minimizing drug exposure. In this work, CFP loaded polymer O-carboxymethyl chitosan (OCMC) microspheres (CFP-OCMC-MPs) were fabricated and their antimicrobial activity against Staphylococcus aureus as well as biocompatibility were evaluated. The microspheres possessed the spherical surface with diameter approximately 7 MUm. Fourier transforms infrared spectral and wide-angle X-ray diffraction analysis showed that CFP was steadily incorporated. The drug loading content and encapsulation efficiency of the microspheres were 21.4 +/- 0.5% and 42.3 +/- 0.7%, respectively. The drug release profiles were found to be biphasic with an initial burst release followed by a gradual release phase, following the Higuchi model. In addition, the CFP-OCMC-MPs were able to kill all the bacteria cultured in suspension within 24 h and exhibited long-lasting bactericidal activity as demonstrated by inhibition zone study. Compared to CFP, CFP-OCMC-MPs showed a milder toxicity toward osteoblast like cells over an 8 day period. All these results suggest that CFP-OCMC-MPs are endowed with sustained treatment of bacterial infection and enhanced biocompatibility. PMID- 27696973 TI - Tracheal tissue-engineering: in-vivo biocompatibility of mechanically-stripped allogenic rabbit trachea with autologous epithelial covering. AB - BACKGROUND: Successful trachea transplantation comprises the use of biocompatible constructs with little immune-reactivity, submucosal revascularization and creation of an epithelial covering. Allogenic chondrocytes might be protected from an overt immune-response due to physical isolation. Our aim was to evaluate in-vivo biocompatibility of allotracheae, stripped of their highly-immunogenic inner lining. Secondly, we established whether these constructs might serve as suitable scaffolds for autologous epithelial grafting. METHODS: Mucosa and submucosa of 12 rabbit donor tracheae were mechanically peeled off. Cartilage was covered with IntegraTM regeneration-template. Constructs were implanted within the recipient's lateral thoracic artery flap. Integra of 6 revascularized allotracheae was grafted with autologous buccal mucosa. Macroscopical, histological analysis and immunohistochemistry were performed. RESULTS: Revascularization and buccal grafting was incomplete in the first 2 circular constructs. To enhance blood-vessel outgrowth, the following 10 transplants were opened longitudinally before implantation. Integra revascularized well. Grafted tracheae showed satisfactory mucosa-adherence, albeit with invasion of migrating epithelium within the Integra-scaffold. CONCLUSIONS: Mechanically-stripped allotracheae exhibited beneficial biocompatibility up to two months. This approach might open doors in the treatment of long-segment tracheal pathologies of which immunosuppression is contra-indicated. Thickness of this layered construct limited practical feasibility of orthotopic transfer, though with further refinements, a clinically-useful transplant could be created. PMID- 27696974 TI - A tool for assessing case history and feedback skills in audiology students working with simulated patients. AB - OBJECTIVE: To develop a tool for assessing audiology students taking a case history and giving feedback with simulated patients (SP). DESIGN: Single observation, single group design. STUDY SAMPLE: Twenty-four first-year audiology students, five simulated patients, two clinical educators, and three evaluators. RESULTS: The Audiology Simulated Patient Interview Rating Scale (ASPIRS) was developed consisting of six items assessing specific clinical skills, non-verbal communication, verbal communication, interpersonal skills, interviewing skills, and professional practice skills. These items are applied once for taking a case history and again for giving feedback. The ASPIRS showed very high internal consistency (alpha = 0.91-0.97; mean inter-item r = 0.64-0.85) and fair-to moderate agreement between evaluators (29.2-54.2% exact and 79.2-100% near agreement; kappaweighted up to 0.60). It also showed fair-to-moderate absolute agreement amongst evaluators for single evaluator scores (intraclass correlation coefficient [ICC] r = 0.35-0.59) and substantial consistency of agreement amongst evaluators for three-evaluator averaged scores (ICC r = 0.62-0.81). Factor analysis showed the ASPIRS' 12 items fell into two components, one containing all feedback items and one containing all case history items. CONCLUSION: The ASPIRS shows promise as the first published tool for assessing audiology students taking a case history and giving feedback with an SP. PMID- 27696975 TI - A genetic features and gene interaction study for identifying the genes that cause hereditary spherocytosis. AB - OBJECTIVE: Hereditary spherocytosis (HS) is a hemolytic disorder characterized by the presence of spherical-shaped red blood cells on the peripheral blood smear. Non-dominant HS cases are due to de novo mutations of the type associated with dominant inheritance or recessive genes. This study is aimed to identify HS related biological mechanisms and predicting HS candidate genes. METHODS: We searched the known HS-related genes from the public databases. By analyzing the gene ontology (GO) and biological pathway of these genes, we extracted the optimal features to encode HS genes. Based on them, we predicted the HS-related genes from genes of whole genomes using the Random Forest classification. We used the gene interaction networks analysis to further identify the core regulatory genes that were related to HS. RESULTS: Forty-one known HS-related genes were found out and encoded. Three hundred and sixty-seven GO terms and ten biological pathway terms were identified as the optimal features for prediction. We subsequently predicted 150 novel HS-related genes and identified the core regulatory genes in the interaction network of predicted and known genes. These features and genes that we identified could complement the genetic features of HS.

AB - Alzheimer's disease and type 2 diabetes are very serious diseases with the latter having been suggested to cause the former. We prepared super-hard rice bread blended with black rice bran (SRBBB), which contained a high amount of resistant starch that showed strong inhibitory activities against beta-secretase and acetylcholinesterase even after heating. Black rice bran showed greater beta secretase inhibitory activity (3.6-fold) than Koshihikari rice. The bran contained more oleic acid and anthocyanin, meaning that it is potentially a biofunctional food with a high antioxidant capacity. Furthermore, aged mice, which were fed a SRBBB diet for four weeks, showed lower amyloid beta 40 peptide in the blood than mice fed a commercial diet (p < 0.01). Additionally, their initial blood glucose levels (BGLs) after 12 weeks of being fed SRBBB were significantly lower than those in the control group. Taken together, our results indicate SRBBB shows promise for inhibiting not only amyloid beta production, but also abrupt increases in postprandial BGLs. PMID- 27696986 TI - Clinical Effect and Efficacy Factors of Modified Piperacillin-Tazobactam Dosing Regimens in Abdominal Tumor Patients with Post-Operative Pneumonia. AB - BACKGROUND: This study was conducted to observe the clinical efficacy of long term piperacillin-tazobactam (TZP) infusion and identify the factors affecting its curative effect against pneumonia in patients who had undergone surgery for abdominal tumor. METHODS: The 100 patients were divided into four clinical groups according to the severity of their infection: Simple pneumonia, pneumonia with pleural effusion, pneumonia and atelectasis, and severe pneumonia. Each group of patients was then divided into control and treatment groups using a completely random design. The control group received TZP as a regular infusion, and the treatment group received TZP as a long-term infusion. The cure time in the different groups was compared according to the administration regimen, and stratified analysis was carried out to identify the efficacy factors of long-term TZP infusion for patients with each kind of pneumonia. RESULTS: The average cure time for TZP differed significantly among the groups. In particular, the average cure times in the simple pneumonia, pneumonia with pleural effusion, pneumonia and atelectasis, and severe pneumonia groups were 6.800 +/- 0.342, 7.320 +/- 0.304, 10.840 +/- 0.571, and 15.942 +/- 0.973 d (p < 0.001). In each group, the usage time of antibiotics in the treatment groups was significantly shorter than in the control group (8.87 +/- 0.64 vs. 15.95 +/- 2.02 d; p < 0.001). The cure times (d) for simple pneumonia and pneumonia and atelectasis were conspicuously lower in the treatment groups than in the control group (5.667 +/- 0.256 vs. 7.846 +/- 0.451; p < 0.001; 9.667 +/- 1.432 vs. 11.923 +/- 0.947; p = 0.024). The factors associated with continuous treatment effectiveness were being male, age <70 years, Acute Physiology and Chronic Health Evaluation score >=17 points, minimum inhibitory concentration of the pathogen 8 mcg/mL, oxygenation index >200 mm Hg, serum procalcitonin concentration >4 ng/mL, and serum albumin <25 g/L. CONCLUSION: Long-term TZP infusion exhibited better clinical efficacy than did traditional treatment in patients with pneumonia after abdominal tumor surgery.

AB - One of the key objectives of the Millennium Development Goals (MDGs) was to improve the lives of infants and children, particularly the reduction of high infant and childhood mortality rates throughout the developing world. This paper examines the experiences of Malawi in tackling the problem of high infant and childhood mortality over recent decades, 1990-2010. We highlight the strategies that were used in Malawi which led to Malawi's stellar performance in achieving the targets set by the MDGs with reference to infant and childhood mortality. The data for the analysis were obtained from Demographic and Health Surveys and from the various censuses the country has conducted. Regression analysis using district as the unit of observation reveals several important factors that have led to the commendable declines in infant mortality. Significant factors included immunisation of infants as well as increasing levels of female education and the availability of skilled birth attendants. What Malawi's case demonstrates is that given a correct mix of strategies, even a poor country such as Malawi can meet some of the lofty targets set by the MDGs. PMID- 27696988 TI - Hospital support services and the impacts of outsourcing on occupational health and safety. AB - BACKGROUND: Outsourcing labor is linked to negative impacts on occupational health and safety (OHS). In British Columbia, Canada, provincial health care service providers outsource support services such as cleaners and food service workers (CFSWs) to external contractors. OBJECTIVES: This study investigates the impact of outsourcing on the occupational health safety of hospital CFSWs through a mixed methods approach. METHODS: Worker's compensation data for hospital CFSWs were analyzed by negative binomial and multiple linear regressions supplemented by iterative thematic analysis of telephone interviews of the same job groups. RESULTS: Non-significant decreases in injury rates and days lost per injury were observed in outsourced CFSWs post outsourcing. Significant decreases (P < 0.05) were observed in average costs per injury for cleaners post outsourcing. Outsourced workers interviewed implied instances of underreporting workplace injuries. CONCLUSIONS: This mixed methods study describes the impact of outsourcing on OHS of healthcare workers in British Columbia. Results will be helpful for policy-makers and workplace regulators to assess program effectiveness for outsourced workers. PMID- 27696998 TI - The Truth About Flossing.

AB - Autophagy is a conserved process in eukaryotic cells for degradation of cellular proteins and organelles. In filamentous fungi, autophagic degradation of organelles such as peroxisomes, mitochondria, and nuclei occurs in basal cells after the prolonged culture, but its mechanism is not well understood. Here, we functionally analyzed the filamentous fungus Aspergillus oryzae AoAtg26, an ortholog of the sterol glucosyltransferase PpAtg26 involved in pexophagy in the yeast Pichia pastoris. Deletion of Aoatg26 caused a severe decrease in conidiation and aerial hyphae formation, which is typically observed in the autophagy-deficient A. oryzae strains. In addition, cup-shaped AoAtg8-positive membrane structures were accumulated in the Aoatg26 deletion strain, indicating that autophagic process is impaired. Indeed, the Aoatg26 deletion strain was defective in the degradation of peroxisomes, mitochondria, and nuclei. Taken together, AoAtg26 plays an important role for autophagic degradation of organelles in A. oryzae, which may physiologically contribute to the differentiation in filamentous fungi. PMID- 27697002 TI - The dangers of using 'negative durations' to estimate pre- and post-migration fertility. AB - To keep childbearing that occurs before and after migration separate from each other, many analysts apply a technique that uses 'negative durations' to estimate the childbearing risks that migrants have before they migrate. This strategy can lead to incorrect results and should be abandoned. In this research note, we use data for births and internal migration in Sweden to highlight how the two types of behaviour can be kept apart conceptually and analytically without use of 'negative durations'. The procedures used can easily be generalized to any similarly linked pair of behaviours. PMID- 27697003 TI - Impact of Virginia's School-Entry Vaccine Mandate on Human Papillomavirus Vaccination Among 13-17-Year-Old Females. AB - BACKGROUND: The link between human papillomavirus (HPV) and anogenital cancers is well established in the literature. Many states have passed laws requiring funding for HPV education or vaccination. Mandatory HPV vaccination policies have been considered and passed in several states; yet their effectiveness has not been evaluated. This study sought to assess the impact of Virginia's HPV vaccine mandate for school-entry on HPV vaccine uptake among females aged 13-17 years. METHODS: Data from the National Immunization Survey-Teen for the 2008-2012 period were used, and 3,203 adolescent females were included in the analysis. We performed difference-in-differences estimation and logistic regression with a policy and period interaction term. Virginia was considered the treatment state, and South Carolina and Tennessee were the comparison states to account for nonpolicy factors that may have affected vaccination rates during the time period considered in the analysis. RESULTS: There was no evidence of an effect of Virginia's HPV vaccine mandate for school-entry on vaccination rates or on physician vaccination recommendation using either the difference-by-differences analysis or the policy and period interaction term in the logistic regression. Physician recommendation was the factor most strongly associated with vaccination in the Virginia-South Carolina analysis (adjusted odds ratio [aOR] = 9.33; 95% confidence interval [CI]: 6.11-14.3) and in the Virginia-Tennessee analysis (aOR = 9.33; 95% CI: 6.11-14.3). CONCLUSION: Study findings suggest that Virginia's HPV vaccine mandate for school-entry did not lead to a significant increase in HPV vaccination among adolescent females or physician recommendations. However, physician recommendation was the factor most strongly associated with vaccination. PMID- 27697004 TI - Intense Pulsed Light: From the Past to the Future. AB - BACKGROUND: For 20 years, intense pulsed light (IPL) technology has been used to treat various medical problems. IPL has since developed rapidly, becoming popular among patients worldwide. Recently, IPL has been used mainly for cosmetic purposes. Researchers are constantly seeking new applications of IPL to meet the increasing needs of patients. OBJECTIVE: This review summarizes the development of IPL devices, discusses the current literature on the clinical application of IPL to increase our understanding of IPL, and provides guidance for broadening its clinical applications. MATERIALS AND METHODS: We performed a systematic search of electronic databases, including MEDLINE and PubMed and the authors experience on IPL to divide IPL development into three stages: germination, growth, and relative maturity. RESULTS: Studies established the classical indications of IPL, including vascular lesions, pigmented lesions, hair growth, and photo rejuvenation. However, trials showed IPL has limited effects for complicated skin problems. Many studies explored rational combination therapies by IPL and laser or other cosmetic technologies. CONCLUSIONS: Based on previous research and the new generation of IPL devices, in the future, we predict wider and more effective clinical applications of IPL through the further improvement of IPL devices and their combined treatment.

PMID- 27697007 TI - Quantitative Liver Function Analysis: Volumetric T1 Mapping with Fast Multisection B1 Inhomogeneity Correction in Hepatocyte-specific Contrast-enhanced Liver MR Imaging. AB - Purpose To determine whether B1 inhomogeneity-corrected volumetric T1 maps of gadoxetic acid-enhanced liver magnetic resonance (MR) imaging are able to demonstrate global liver function and functional heterogeneity in patients with cirrhosis and to investigate their relationship with the development of hepatic insufficiency and decompensation. Materials and Methods This institutional review board-approved retrospective study with waiver of informed consent included 234 consecutive patients who underwent gadoxetic acid-enhanced liver MR imaging, including B1 inhomogeneity-corrected volumetric T1 mapping. For all patients, T1 relaxation times of the liver and liver volumes were measured on T1 maps. Liver T1 and functional liver volume-to-weight ratio (liver volume divided by liver T1 and the patient's weight) were compared between Child-Pugh class A and class B cirrhosis. Associations between serum markers, MR parameters, hepatic insufficiency, and decompensation were investigated by using Cox proportional hazards analysis. Results Patients with Child-Pugh class B disease showed significantly longer liver T1 (548.2 msec +/- 257.7 vs 372.2 msec +/- 77.5, P < .0001) and lower kurtosis of liver T1 (29.1 +/- 39.6 vs 43.9 +/- 64.9, P = .016) than patients with Child-Pugh class A disease. Prolonged liver T1 (>=462 msec) (hazard ratio [HR], 5.9; 95% confidence interval [CI]: 1.1, 62.8) and an albumin level of less than 3.5 g/dL (HR, 20.7; 95% CI: 3.9, 221.9) were independently associated with the development of hepatic insufficiency. Functional liver volume to-weight ratio was associated with the development of hepatic decompensation in patients with Child-Pugh class A disease (HR, 0.03; 95% CI: 0.004, 0.23). Conclusion B1 inhomogeneity-corrected volumetric T1 mapping provided information on global liver function and demonstrated functional heterogeneity. In addition, prolonged liver T1 (>=462 msec) was associated with the development of hepatic insufficiency, and functional liver volume-to-weight ratio was negatively related with the development of decompensation in compensated cirrhosis.

PMID- 27697006 TI - Meniscal Surgery: Risk of Radiographic Joint Space Narrowing Progression and Subsequent Knee Replacement-Data from the Osteoarthritis Initiative. AB - Purpose To investigate the risk of radiographic joint space narrowing (JSN) progression evaluated in subjects with and those without underlying osteoarthritis at baseline and knee replacement (KR) associated with meniscal surgery in subjects with and those without a reported history of preceding knee trauma. Materials and Methods The HIPAA-compliant protocol was approved by the institutional review boards of the participating centers. Written informed consent was obtained from all participants. Subjects who underwent meniscal surgery with a preceding knee trauma at baseline (n = 564) and those without (n = 147) were drawn from the Osteoarthritis Initiative cohort (n = 4796). Radiographic JSN progression was evaluated by using Osteoarthritis Research Society International grading (progression in 1st-, 2nd-, 3rd-, 4th-, 6th-, or 8th-year radiographic findings compared with baseline). KR was assessed up to the 9th year of study (days passed from inclusion to KR or last follow-up). Cox hazard analysis was used to extract the adjusted hazard ratios (HRs) with adjustments for baseline age, sex, body mass index, physical activity, symptoms, and radiographic osteoarthritis features (Kellgren and Lawrence [KL] grade). Results Meniscal surgery with a history of preceding knee trauma was not associated with radiographic progression of JSN (adjusted HR, 0.91 [95% confidence interval {CI}: 0.78, 1.07]) or KR (adjusted HR, 1.02 [95% CI: 0.79, 1.34]; P = .854). However, meniscal surgery without a history of preceding knee trauma was associated with radiographic progression of JSN (adjusted HR, 1.27 [95% CI: 1.00, 1.63]) and KR (adjusted HR, 2.09 [95% CI: 1.52, 2.89]; P < .001). Additionally, there was a higher risk of KR in subjects with radiographic KL grade of less than 2 (adjusted HR, 6.97 [95% CI: 3.56, 13.64]; P < .001) at baseline in comparison with KL grade of at least 2 (adjusted HR, 1.76 [95% CI: 1.22, 2.54]; P < .05). Conclusion In contrast to subjects without a reported preceding trauma, meniscal surgery is not independently associated with increased risk of radiographic JSN progression and KR in patients with a reported preceding trauma.

PMID- 27697008 TI - Noninvasive Assessment of Renal Fibrosis with Magnetization Transfer MR Imaging: Validation and Evaluation in Murine Renal Artery Stenosis. AB - Purpose To test the utility of magnetization transfer imaging in detecting and monitoring the progression of renal fibrosis in mice with unilateral renal artery stenosis. Materials and Methods This prospective study was approved by the Institutional Animal Care and Use Committee. Renal artery stenosis surgery (n = 10) or sham surgery (n = 5) was performed, and the stenotic and contralateral kidneys were studied longitudinally in vivo at baseline and 2, 4, and 6 weeks after surgery. After a 16.4-T magnetic resonance imaging examination, magnetization transfer ratio was measured as an index of fibrosis (guided by parameters selected in preliminary phantom studies). In addition, renal volume, perfusion, blood flow, and oxygenation were assessed. Fibrosis was subsequently measured ex vivo by means of histologic analysis and hydroxyproline assay. The Wilcoxon rank sum or signed rank test was used for statistical comparisons between or within groups, and Pearson and Spearman rank correlation was used to compare fibrosis measured in vivo and ex vivo. Results In the stenotic kidney, the median magnetization transfer ratio showed progressive increases from baseline to 6 weeks after surgery (increases of 13.7% [P = .0006] and 21.3% [P = .0005] in cortex and medulla, respectively), which were accompanied by a progressive loss in renal volume, perfusion, blood flow, and oxygenation. The 6 week magnetization transfer ratio map showed good correlation with fibrosis measured ex vivo (Pearson r = 0.9038 and Spearman rho = 0.8107 [P = .0002 vs trichrome staining]; r = 0.9540 and rho = 0.8821 [P < .0001 vs Sirius red staining]; and r = 0.8429 and rho = 0.7607 [P = .001 vs hydroxyproline assay]). Conclusion Magnetization transfer imaging was used successfully to measure and longitudinally monitor the progression of renal fibrosis in mice with unilateral renal artery stenosis.

PMID- 27697009 TI - Intensity of Integrated Primary and Specialist Home-Based Palliative Care for Chronic Diseases in Northeast Italy and Its Impact on End-of-Life Hospital Access. AB - BACKGROUND: Hospital admissions at the end of life (EOL) represent an established indicator of poor quality of care. OBJECTIVE: To examine the impact of intensity of integrated primary and specialist home-based palliative care for chronic diseases (HPCCD) plans of care on EOL hospital access. METHODS: Retrospective population-based study using linked mortality, hospitalization, and home care data. Intensity of HPCCD was measured 90-31 days before death; outcomes were hospital death and prolonged hospital stay for medical reasons in the last month of life. Outcomes were modeled through Poisson and quartile regressions. Adults aged 65-84 years with at least an ordinary hospitalization and a drug treatment in the year before death, who died from nononcological chronic diseases in the Veneto Region, January 2012-December 2013, were included. RESULTS: Among 2087 patients, 1016 (48.7%) did not receive any HPCCD homecare visit; 860 (41.2%), 152 (7.3%), and 59 (2.8%) had <2, 2-4, and 4-7 homecare visits/week, respectively. Hospital death occurred for 1310 patients (62.8%) and the median hospital stay in the last month of life was five days (interquartile range 0-14). In multivariate analysis, a higher intensity of HPCCD was associated with lower rates of prolonged (>=14 days) EOL hospitalization and hospital death with a dose-response relationship. When no access to HPCCD was compared with 2-4 visits/week, adjusted percentage of hospital death decreased by -18.4% (95% confidence interval [CI] 5.4% to -29.7%) and the length of hospital stay decreased by 37.9% (95% CI 16.7% 56.0%). CONCLUSIONS: The intensity of integrated HPCCD plans of care was associated with a reduction in EOL hospital stay and in hospital death.

PMID- 27697018 TI - The hypothetical roles of arsenic in multiple sclerosis by induction of inflammation and aggregation of tau protein: A commentary. AB - Multiple sclerosis (MS) is a disease which manifests demyelination of neuronal cells in the brain. Despite extensive research on the mechanisms of disease development and progression, the exact mechanism is not elucidated yet, which has hampered drug development and subsequent treatment of the disease. We have recently shown that the serum levels of arsenic and malondialdehyde, a lipid peroxidation marker, are high in MS patients. In this article, we would like to formulate the hypothesis that arsenic may cause MS by induction of inflammation, degeneration, and apoptosis in neuronal cells. The induction of ROS generation in cells upon exposure to arsenic as a heavy metal may be involved in the pathogenesis of MS. Tau protein, a member of the family of microtubule-associated proteins, is mainly expressed in neurons and contribute to the assembly of neuronal microtubules network. Arsenic may affect the hyperphosphorylation and aggregation of tau proteins and may be involved in the cascade leading to deregulation of tau function associated with neurodegeneration. For validation of this hypothesis, studies might be conducted to evaluate the association of arsenic levels and tau protein levels in MS patients. Further studies might also focus on the trafficking along microtubules in neurons of MS patient with regard to hyperphosphorylation of tau protein. This hypothesis may add a new dimension to the understanding of MS etiology and help to design novel therapeutic agents against potential targets that might be discovered. If this hypothesis proves to be true, tau phosphorylation inhibitors can be potential candidates for MS drug development.

AB - The pre-operative assessment is used to clarify issues prior to surgery that can change management provided by a multidisciplinary team. A high proportion of rheumatoid arthritis patients are elderly requiring orthopaedic surgery which requires further investigations, assessment of risk through functional capacity and several anaesthetic considerations. Rheumatoid arthritis patients often provide a variety of medical issues that can be found on careful and thorough pre assessment that can be accommodated for by the surgical and anaesthetic team, however aspects of holistic management is an important considerations for efficient and effective management. PMID- 27697019 TI - Identification, production and assessment of two Toxoplasma gondii recombinant proteins for use in a Toxoplasma IgG avidity assay. AB - The IgG avidity assay is an important tool in the management of suspected toxoplasmosis in pregnant women. This study aimed to produce new Toxoplasma gondii recombinant proteins and to assess their usefulness in an IgG avidity assay. Toxoplasma positive and negative serum samples were used, the former were categorized into low (LGA) and high (HGA) IgG avidity samples. Immunoblots were performed on 30 T. gondii cDNA clones to determine the reactivity and IgG avidity to the expressed proteins. Two of the clones were found to have diagnostic potential and were analyzed further; AG12b encoded T. gondii apical complex lysine methyltransferase (AKMT) protein and AG18 encoded T. gondii forkhead associated (FHA) domain-containing protein. The His-tagged recombinant proteins, rAG12b and rAG18, were expressed and tested with LGA and HGA samples using an IgG avidity western blot and ELISA. With the IgG avidity western blot, rAG12b identified 86.4% of LGA and 90.9% of HGA samples, whereas rAG18 identified 81.8% of both LGA and HGA samples. With the IgG avidity ELISA, rAG12b identified 86.4% of both LGA and HGA samples, whereas rAG18 identified 77.3% of LGA and 86.4% of HGA serum samples. This study showed that the recombinant antigens were able to differentiate low avidity and high avidity serum samples, suggesting that they are potential candidates for use in the Toxoplasma IgG avidity assay.

AB - BACKGROUND: Myelodysplastic syndromes (MDS) represent a heterogeneous group of clonal disorders of hematopoietic system, characterized by genetic, epigenetic or microenvironmental alterations of aging hematopoietic stem cells. Pathophysiology of MDS comprises the suppression of normal hematopoiesis and reduced myeloid progenitor cells differentiation, with the main consequence of peripheral cytopenias and increased risk to evolution in acute myeloid leukemia (AML). METHOD: This review summarizes the evolving understanding of the role of genetic and epigenetic alterations involved in pathogenesis and current and future strategies for therapeutic targeting in myelodysplastic syndromes. RESULTS: In addition to molecular characteristics, immune and microenvironmental factors in bone marrow of MDS patients may further modify the MDS manifestations, its clinical presentation, disease course, risk of transformation to AML and prognosis of MDS, as well as response to therapy. Current clinical response to therapy approaches are exerted both by epigenetic alterations and by induction of apoptosis. CONCLUSION: Future treatment strategies in preclinical and clinical investigations are directed towards new dosing schedules of existing drugs, new genetic and epigenetic targets and combination of different agents, including hypomethylation agents and histone deacetylase inhibitors. PMID- 27697024 TI - Systems Toxicology: Systematic Approach to Predict Toxicity. AB - Drug discovery is complex and expensive. Numerous drug candidates fail late in clinical trials or even after being released to the market. These failures are not only due to commercial considerations and less optimal drug efficacies but, adverse reactions originating from toxic effects also constitute a major challenge. During the last two decades, significant advances have been made enabling the early prediction of toxic effects using in silico techniques. However, by design, these essentially statistical techniques have not taken the disease driving pathophysiological mechanisms into account. The complexity of such mechanisms in combination with their interactions with drugspecific properties and environmental and life-style related factors renders the task of predicting toxicity on a purely statistical basis which is an insurmountable challenge. In response to this situation, an interdisciplinary field has developed, referred to as systems toxicology, where the notion of a network is used to integrate and model different types of information to better predict drug toxicity. In this study, we briefly review the merits and limitations of such recent promising predictive approaches integrating molecular networks, chemical compound networks, and protein drug association networks. PMID- 27697025 TI - Immunological Mechanisms of Drug Hypersensitivity. AB - Drug hypersensitivity reactions (DHRs) are adverse drug reactions that may be divided into several categories; namely pharmacologic intolerance, idiosyncratic reactions, pseudo-allergic reactions and allergic reactions. Drug allergic reactions are those DHRs that are mediated by either antibodies or drug-specific T cells. They vary in terms of severity, time-to-onset of clinical manifestations and target organ. Skin is most commonly implicated in drug hypersensitivity reactions; however, it is now apparent that reactions targeting internal organs fall under the definition of drug hypersensitivity. Multiple hypotheses have been proposed to explain the diverse immune mechanisms involved and the heterogeneous clinical presentation. The discovery of human leukocyte antigen (HLA) risk alleles for some DHRs has provided insights in the pathogenesis of these reactions. In this review we summarize immune cells involved in DHRs, discuss the possible immunological mechanisms of DHRs, with an emphasis on the IgE-mediated immediate reactions and T cell-dependent delayed type reactions. PMID- 27697027 TI - Drug Metabolism and Pharmacokinetics of Dammarane Triterpenoids. AB - Dammarane triterpenoids are widely distributed in plants and are implicated in various bioactivities and pharmacological effects. This review focuses on advancements in dammarane triterpenoid metabolism, particularly drug design and development, including radiolabeling, absorption, distribution, metabolism, excretion, and pharmacokinetics, which can accurately describe the behaviors of dammarane triterpenoids. This review contributes to the systematic and consistent research and development of dammarane triterpenoids. Their structures and activities, radiolabel application, absorption, distribution, and pharmacokinetic characteristics, possible degradation pathways, metabolic enzyme induction or inhibitory effect, and structure-activity relationships have been described. New intranasal and intra-tympanic administration routes and microdialysis technology have also been introduced. These techniques not only improve the limits of dammarane triterpenoids on absorption and distribution but also facilitate the design and study of these compounds as potential drugs. PMID- 27697026 TI - Mechanisms of Tubulin Binding Ligands to Target Cancer Cells: Updates on their Therapeutic Potential and Clinical Trials. AB - BACKGROUND: A number of chemically diverse substances bind to the tubulin and inhibit cell proliferation by disrupting microtubule dynamics. There are four binding sites for the ligands binding to the tubulin; taxane/epothilone and laulimalide/peloruside binding ligands stabilize microtubule while vinca and colchicine binding site agents promote microtubule depolymerization. Most of the tubulin binding ligands disturb the tubulin-microtubule dynamic equilibrium but these may exhibit anticancer activities through different mechanisms. Taxanes and epothilones are widely used cytotoxic agents and are found effective against different types of human malignancies. However, taxanes are susceptible to pgp mediated multi-drug resistance, dose limiting hematopoietic toxicity and cumulative neurotoxicity. Vinca alkaloids are already in clinical practice, but ligands binding to the colchicine site are still in the different stages of clinical trials. OBJECTIVE: In the current review article, plausible mechanistic details about the interactions of ligands at the binding pocket and subsequent changes in the tubulin structure are described. The review article also illustrated different formulations of the tubulin binding agents in combination with other chemotherapeutic agents and their therapeutic potential against various human malignancies. CONCLUSION: Tubulin targeting agents emerged as one of the most successful anticancer drugs and a number of structurally different chemical compounds are in advance stages of clinical development. PMID- 27697028 TI - Advances in Drug Discovery: Impact of Genomics and Role of Analytical Instrumentation. AB - Drug discovery is a highly complicated, tedious and potentially rewarding approach associated with great risk. Pharmaceutical companies literally spend millions of dollars to produce a single successful drug. The drug discovery process also need strict compliance to the directions on manufacturing and testing of new drug standards before their release into market. All these regulations created the necessity to develop advanced approaches in drug discovery. The contributions of advanced technologies including high resolution analytical instruments, 3-D biological printing, next-generation sequencing and bioinformatics have made positive impact on drug discovery & development. Fortunately, all these advanced technologies are evolving at the right time when new issues are rising in drug development process. In the present review, we have discussed the role of genomics and advanced analytical techniques in drug discovery. Further, we have also discussed the significant advances in drug discovery as case studies. PMID- 27697029 TI - Fatty Acid Composition of Mangrove Wild Legume Seeds (Sesbania speciosa) in Southwestern India. AB - BACKGROUND: This study compares the composition of fatty acid methyl esters (FAMEs) in seeds of Sesbania speciosa (dry and mature) after processing (uncooked and cooked) and extraction (hot and cold). METHODS: Among PUFA, oleic, linoleic and linolenic acids were common to uncooked and cooked dry seeds which were high on cold extraction. Only two fatty acid ratios were favorable in hot extraction [(C14:0 + C15:0 + (C16:0 / C18:0) and C18:1 / C18:2]. RESULTS: Cold extraction yielded docosahexaenoic acid in uncooked as well as cooked dry seeds and all fatty acid ratios were nutritionally favorable. In mature seeds, lauric and myristic acids were high on hot extraction, while palmitic and stearic acids were high on cold extraction. Except for omega-6/omega-3 ratio, the rest fatty acid ratios in mature seeds on hot extraction were not favorable, while cold extraction resulted in three favorable ratios (TUFA/TSFA, TPUFA/TMUFA and omega 6/omega-3). Three-way ANOVA on the impact of seeds, process and extraction of major fatty acids revealed significant difference only between extraction methods (p < 0.001). CONCLUSION: Overall, the cold extraction for dry as well as mature seeds were advantageous for essential fatty acids profile. Some of the recent patents are dealing with antineoplastic compounds as well as radioprotective drugs derived from Sesbania speciosa. PMID- 27697030 TI - In Vitro Study of the Antifungal Activity of Essential Oils Obtained from Mentha spicata, Thymus vulgaris, and Laurus nobilis. AB - BACKGROUND: The aim of this study was to determine the antifungal activity of the essential oils isolated from three aromatic plants against 13 filamentous fungal strains. METHODS: The major constituents of Mentha spicata, Thymus vulgaris, and Laurus nobilis essential oils were carvone (52.2%), linalool (78.1%), and 1,8 cineole (45.6%), respectively. There are also some patents suggesting the use of essential oils as natural and safe alternatives to fungicides for plant protection. RESULTS: In the present work, M. spicata essential oil exhibited the strongest activity against all tested fungi in which Fusarium graminearum, F.moniliforme, and Penicillium expansum were the most sensitive to mint oil with lower minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) values of 2.5 MUL mL-1 (v/v). Thymus vulgaris essential oil was less active compared to the oil of M. spicata. Aspergillus ochraceus was the most sensitive strain to thyme oil with MIC and MFC values of 2.5 and 5 MUL mL-1, respectively. Thymus vulgaris essential oil also exhibited a moderate fungicidal effect against the tested fungi, except for A. niger (MFC >20 MUL-1). L. nobilis essential oil showed a similar antifungal activity with thyme oil in which A. parasiticus was the most resistant strain to this oil (MFC >20 MUL mL-1). CONCLUSION: Our findings suggested the use of these essential oils as alternatives to synthetic fungicides in order to prevent pre-and post-harvest infections and ensure product safety. PMID- 27697031 TI - Reactivation of latent HIV-1 in latently infected cells by coumarin compounds: Hymecromone and ScoparoneReactivation of Latent HIV-1 in Latently Infected Cells by Coumarin Compounds: Hymecromone and Scoparone. AB - BACKGROUND: Current antiretroviral therapy (ART) cannot cure HIV-1 infection due to the presence of latent viral reservoirs. The "shock and kill" strategy is a promising approach to eliminate the viral reservoir. However, there are various limits existing in current latency-reversing agents, searching for new activators are urgently needed. OBJECTIVE: The present study aimed at investigating the ability of hymecromone and scoparone for activating HIV-1 from latent reservoirs. METHODS: Jurkat T cell model of HIV-1 latently were used to evaluate the effect of hymecromone and scoparone. The percentage of green florescence protein expression as a marker for reactivation of HIV-1 promoter was measured via FACScan. The expression of CD25 and CD69 in human peripheral blood mononuclear cells was measured by flow cytometry at 72 h post-treatment with hymecromone or scoparone or prostratin using antibodies against CD25 and CD69. RESULTS: Hymecromone and scoparone can induce HIV-1 LTR reactivation in a dose and timedependent. We further show that hymecromone and scoparone can reactivate latent virus without inducing the activation of global T cells. We also found that scoparone acts by NF-&kgr;B signal pathway. CONCLUSION: Hymecromone and scoparone can effectively reactivate latent HIV-1 with low cellular toxicity, indicating hymecromone and scoparone might be potential drugs for HIV-1 reservoir eradication strategies in the future. PMID- 27697032 TI - Prevalence of HIV-1 Subtypes and Antiretroviral Drug Resistance Mutations in Nepal. AB - BACKGROUND: There have been very few reports of HIV-1 subtypes and drug resistance mutations (DRMs) from Nepal which is geographically located between two high-prevalence HIV-1 infection countries, China and India. OBJECTIVE: The aim of this study was to determine prevalence of acquired and transmitted DRMs and HIV-1 subtypes in Nepal. METHODS: Thirty-five HIV-1 seropositive samples from central region of Nepal were collected in 2011. The subjects were divided into two groups, antiretroviral (ARV) drug naive group (n=15) and antiretroviral treatment (ART) group (n=20), 90% (18/20) of them received zidovudine, lamivudine and nevirapine (AZT/3TC/NVP) regimen. HIV pol (protease and reverse transcriptase regions) nucleotide sequences were analyzed by Viroseq HIV-1 Genotyping System. Nearly full-length genomic (NFLG) sequences of 10 samples were performed. RESULTS: NFLG genotyping revealed that 80% of samples were infected with subtype C and 20% with recombinants (C/D/H and C/A). Phylogenetic analysis of 35 pol sequences from Nepal were subtype C. The prevalence of acquired DRMs to NNRTIs and NRTIs was 15% (3/20). DRMs to NVP, K103N and V179D, and to NRTIs were observed at 11.1% (2/18) and 5% (1/20), respectively. The prevalence of DRMs to rilpivirine for E138A/G was 5.7%. The minor protease inhibitors (PI) associated mutations (A71T/V and T74S) were observed in 5/35 (14.3%) subjects. CONCLUSION: This is the first report of NFLG HIV-1 genomic sequences and DRMs from Nepal. National surveillance of HIV DRMs to ARVs and molecular epidemiology study should be done annually for better prevention and treatment of HIV infection in Nepal. PMID- 27697034 TI - Playing Modular Puzzle with Adhesion/Growth-Regulatory Galectins: Design and Testing of a Hybrid to Unravel Structure-Activity Relationships. AB - The potent multifunctionality of human galectins is based on their modular structure in a not yet fully understood manner. A strategy to dissect the contributions of individual sequence stretches to lectin activity is based on engineering variants of the natural proteins, which are composed of novel combinations of distinct parts. On proof-of-principle level, we here describe the design of a hybrid constituted by the N-terminal tail of chimera-type galectin-3 and the Nterminal carbohydrate recognition domain of tandem-repeat-type galectin 8, its production, purification and its serine phosphorylation characteristic for galectin- 3's tail. As measured for the respective parental proteins, its binding to (neo)glycoproteins is specific for beta-galactosides and inhibitable by lactose, with KD-value closer to galectin-8 than galectin-3. Cell surface staining indicated similarity of the hybrid's reactivity to O-glycans and sensitivity for sialylation to respective properties of tandem-repeattype galectin-8 and its N-terminal domain. Applied as histochemical tool on tissue sections of murine jejunum and epididymis, intense lactose-inhibitable signals were recorded intracellularly, with a distribution profile akin to that of galectin-3. Tested as agglutinin, the hybrid was potent, excelling wild-type control galectins. The chimera-type design can thus serve as platform for tuning crosslinking activity. PMID- 27697035 TI - Protective Effects of Dietary Flavonoids in Diabetic Induced Retinal Neurodegeneration. AB - BACKGROUND: Diabetic retinopathy is one of the serious complications of diabetes and the leading cause of decreased vision and blindness worldwide. Neurodegeneration has been recognized as initiating factor in causing the retinal damage, which leads to micro-vascular damage in diabetic retinopathy. Diabetes induced oxidative stress is believed to be the key factor that damages neurons in the diabetic retina. Various therapeutic approaches for effective attenuation of increased oxidative stress by antioxidants have emerged. One such approach is to utilize dietary flavonoids, which have been found to possess powerful antioxidant activity. Some of the naturally occurring flavones possess anti-diabetic effects by enhancing insulin sensitivity and reducing plasma glucose levels in diabetic animal models. OBJECTIVE: Considering the importance of developing new antioxidant compounds and the relevance of their applications in the treatment of diabetes and its complications, in this review article, we discuss and highlight various neuroprotective mechanisms of flavonoids in the diabetic retina. RESULTS: Dietary supplementation of flavonoids to diabetics may reduce oxidative stress, which in turn might ameliorate apoptosis and the levels of neurotrophic factors in the diabetic retina. CONCLUSION: This approach will elucidate a novel strategy for preventing and treating diabetic retinoneuropathy the leading cause of low vision and blindness. PMID- 27697036 TI - Formulation and Characterization of a Ternary Inclusion Complex Containing Hydroxypropyl-beta-cyclodextrin and Meglumine for Solubility Enhancement of Poorly Water-Soluble ST-246, an Anti-Smallpox Drug. AB - BACKGROUND: The solubilization of poorly water-soluble drugs remains challenging. The purpose of this study was to design a liquid formulation that can improve the solubility of poorly water-soluble and weakly acidic ST-246, an anti-smallpox drug. METHODS: Soluble ternary cyclodextrin complexations (t-CDs) containing ST 246, 2-hydroxypropyl-beta- cyclodextrin (HP-beta-CD) and meglumine (MEG) were prepared and optimized. The optimized t-CDs were further characterized using a scanning electron microscope (SEM), Powder X-ray Diffractometry (PXRD), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR) and Nuclear Magnetic Resonance Spectroscopy (NMR). RESULTS: The solubility of ST-246 improved dramatically from 3 ug/ml (in water, 37 degrees C) to 50 mg/ml in the optimized t-CDs (ST-246/MEG/HP-beta-CD, 1:2:6 weight ratio). The results suggested that the drug was associated with MEG through hydrogen bonds and then included into the hydrophobic cavity of HP-beta-CD, which might be a major factor for solubility improvement. To determine the exact inclusion mechanism, a Phase Soluble Study (PSS) was also conducted, and it indicated that a 1:1 soluble complex was formed between ST-246 and HP-beta-CD and that the action mechanism of MEG was complicated and relied on more than pH modulation. CONCLUSION: Generally, the optimized ternary cyclodextrin complexation might be a potential formulation strategy for enhancing the solubility and bioavailability of poorly water-soluble ST-246.

AB - BACKGROUND: Recombinant antibody fragments are promising alternatives to full length immunoglobulins and offer important advantages compared with conventional monoclonal antibodies: extreme specificity, higher affinity, superior stability and solubility, reduced immunogenicity as well as easy and inexpensive large scale production. OBJECTIVE: In this article we will review and discuss recombinant antibodies that are being evaluated for neurodegenerative diseases in pre-clinical models and in clinical studies and will summarize new strategies that are being developed to optimize their stability, specificity and potency for advancing their use. METHODS: Articles describing recombinant antibody fragments used for neurological diseases were selected (PubMed) and evaluated for their significance. RESULTS: Different antibody formats such as single-chain fragment variable (scFv), single-domain antibody fragments (VHHs or sdAbs), bispecific antibodies (bsAbs), intrabodies and nanobodies, are currently being studied in pre-clinical models of cancer as well as infectious and autoimmune diseases and many of them are being tested as therapeutics in clinical trials. Immunotherapy approaches have shown therapeutic efficacy in several animal models of Alzheimer's disease (AD), Parkinson disease (PD), dementia with Lewy bodies (DLB), frontotemporal dementia (FTD), Huntington disease (HD), transmissible spongiform encephalopathies (TSEs) and multiple sclerosis (MS). It has been demonstrated that recombinant antibody fragments may neutralize toxic extra- and intracellular misfolded proteins involved in the pathogenesis of AD, PD, DLB, FTD, HD or TSEs and may target toxic immune cells participating in the pathogenesis of MS. CONCLUSION: Recombinant antibody fragments represent a promising tool for the development of antibody-based immunotherapeutics for neurodegenerative diseases. PMID- 27697037 TI - Physicochemical, Pharmacodynamic and Pharmacokinetic Characterization of Soluplus Stabilized Nanosuspension of Tacrolimus. AB - BACKGROUND: Tacrolimus, an immunosuppressive drug has a variable pharmacokinetic and poor oral bioavailability due to poor solubility. The aim of the present study was enhancing the solubility and oral bioavailability of this drug. METHODS: Tacrolimus nanoparticles were prepared by precipitation anti-solvent evaporation method. The effect of different parameters including: surfactant type, solvent to nonsolvent ratio and drug to surfactant ratio were studied on the particle size, saturated solubility and dissolution rate of the drug. The solid state characterization was done by fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), X-ray powder diffraction (XRPD) and scanning electron microscopy. The untreated drug (5 mg.kg-1day-1), nanoparticles or physical mixture of the drug and the stabilizers were administered to rats and blood levels of tacrolimus were assessed by electrochemiluminence method. The oral drug administration was done for 10 days then the changes in white blood cells (WBC) and percent lymphocyte count were determined before drug administration, 5 and 10 days after drug administration. RESULTS: FTIR spectroscopy showed no interaction between the drug and stabilizers. XRPD and DSC studies indicated the amorphous state of the drug in nanosuspensions. The solvent to nonsolvent ratio of 1:20 and drug to surfactant ratio of 1:3 enhanced 185 fold the saturated solubility and 17 fold dissolution rate of the drug. In vivo studies also showed tacrolimus nanoparticles significantly reduced the lymphocyte and WBC, enhanced 66 and 34 fold the AUC0-24 and Cmax of the drug, respectively. CONCLUSION: The precipitation anti-solvent evaporation is a nano-crystalization technique which showed to be an effective approach for enhancing water solubility and bioavailability of tacrolimus.

Bruton's tyrosine kinase (BTK), is described as a possible target in a many B-cell neoplasms. Ibrutinib is the most used inhibitor of BTK and has great tolerability and efficacy in chronic lymphocytic leukemia. This review summarizes results with ibrutinib in clinical trials and novel BTK inhibitors of interest. PMID- 27697039 TI - Therapeutic Effects of Rivastigmine and Alfa-Lipoic Acid Combination in the Charles Bonnet Syndrome: Electroencephalography Correlates. AB - BACKGROUND: Charles Bonnet Syndrome (CBS) is a rare clinical condition which is characterized by complex hallucinations in visually impaired patients. The pathophysiology of this disorder remains largely unknown, and there is still no proven treatment for this disease. In our study, we aimed to investigate the neural activity through Electroencephalography (EEG) power and evaluate the effect of rivastigmine in combination with alpha-lipoic acid on hallucination in two CBS patients with diabetic retinopathy. METHODS: EEG data was recorded with standard routine EEG protocols for both patients in our electrophysiological research laboratory (REMER Clinical Electrophysiology and Neuromodulation Research and Application Laboratory) with Brain Vision Recorder (Brainproduct, Munich, Germany). All spectral analyses were processed by BrainVision Analyzer 2 (Brainproduct, Munich, Germany, 2.0.4 Version) in 128 Hz sample rates and the EEG recording and analysis was performed before the administration of rivastigmine (4.5 mg/daily and five patch daily for the first and second patients, respectively) in combination with alpha-lipoic acid (600 mg/daily) for both patients while they were not hallucinated during the time period recordings. Based on our measurement protocol, we have compared the patients in the study group with the three control subjects who were found to be normal except of visual disturbances secondary to significant diabetic retinopathy. RESULTS: Highest theta power values were found in right occipital and left temporo parietal regions for first and second CBS patients, respectively. Additionally, power spectra were lower in two cases as compared to their control groups in the alpha band for all electrodes. We have also shown that acid rivastigmine in combination with alpha-lipoic exerted significant anti-hallucinatory efficiency. CONCLUSION: Our present findings could support the hypothesis that increased activation of specific areas in the source monitoring system plays an important role in the pathogenesis of CBS. In addition, rivastigmine in combination with alpha-lipoic acid could be a new valuable option for CBS patients. PMID- 27697041 TI - A Comprehensive Review on the Biological and Pharmacological Activities of Rhodanine Based Compounds for Research and Development of Drugs. AB - At present, diseases resulting from various reasons have been causing deadly fears to humans and previously incogitable losses to health. Meanwhile, the patient compliance has been weakening because of drug resistance and serious drug adverse effects. There is therefore an urgent need for the development of novel structural agents. Rhodanine derivatives have exhibited wide biological activities, as well as significant industrial applications, which suggests that rhodanine heterocycle represents a key structural motif in heterocyclic chemistry and occupies a prominent position in drug discovery. Here, we review some deadly defects of clinical medicines to the therapy of diseases and important advances on rhodanine derivatives in drug researches (e.g. as anti-diabetic, anti-viral, antiinflammatory, anti-microbial, anti-tumor agents and inhibitors for Alzheimer Disease), indicating that rhodanine heterocycle could be used as a significant pharmacophore to develop novel pharmacological active molecules. It is believed that the review is of importance for new ideas in the development of and rational designs of rhodanine-based drugs. PMID- 27697042 TI - Animal Venom Peptides: Potential for New Antimicrobial Agents. AB - Microbial infections affect people worldwide, causing diseases with significant impact on public health, indicating the need for research and development of new antimicrobial agents. Animal venoms represent a vast and largely unexploited source of biologically active molecules with attractive candidates for the development of novel therapeutics. Venoms consist of complex mixtures of molecules, including antimicrobial peptides (AMPs). Since the discovery of AMPs, they have been studied as promising new antimicrobial drugs. Amongst the remarkable sources of AMPs with known antimicrobial activities are ants, bees, centipedes, cone snails, scorpions, snakes, spiders, and wasps. The antimicrobial tests against bacteria, protozoans, fungi and viruses using 170 different peptides isolated directly from crude venoms or cDNA libraries of venom glands are listed and discussed in this review, as well as hemolytic ativity. The potential of venoms as source of new compounds, including AMPs, is extensively discussed. Currently, there are six FDA-approved drugs and many others are undergoing preclinical and clinical trials. The search for antimicrobial "weapons" makes the AMPs from venoms promising candidates. PMID- 27697043 TI - The Antibacterial Activity of Metal Complexes Containing 1,10- phenanthroline: Potential as Alternative Therapeutics in the Era of Antibiotic Resistance. AB - The "antibiotic era", characterized by the overuse and misuse of antibiotics, over the last half-century has culminated in the present critical "era of resistance". The treatment of bacterial infections is challenging because of a decline in the current arsenal of useful antibiotics and the slow rate of new drug development. The discovery of a new gene (mcr-1) in 2015, which enables bacteria to be highly resistant to polymyxins (such as colistin), the last line of antibiotic defence left, heralds a new level of concern as this gene is susceptible to horizontal gene transfer, with alarming potential to be spread between different bacterial populations, suggesting that the progression from "extensive drug resistance" to "pan-drug resistance" may be inevitable. Clearly there is a need for the development of novel classes of anti-bacterial agents capable of killing bacteria through mechanisms that are different to those of the known classes of antibiotics. 1,10-phenanthroline (phen) is a heterocyclic organic compound which exerts in vitro antimicrobial activity against a broad spectrum of bacteria. The antimicrobial activity of phen can be significantly modulated by modifying its structure. The development of metal-phen complexes offers the medicinal chemist an opportunity to expand such structural diversity by controlling the geometry and varying the oxidation states of the metal centre, with the inclusion of appropriate auxiliary ligands in the structure, offering the opportunity to target different biochemical pathways in bacteria. In this review, we summarize what is currently known about the antibacterial capability of metal-phen complexes and their mechanisms of action. PMID- 27697044 TI - Challenges and Persistent Questions in the Treatment of Trichomoniasis. AB - Trichomoniasis is a sexually transmitted disease (STD) caused by infection with the protozoan parasite Trichomonas vaginalis. It is considered the most prevalent non-viral sexually transmitted disease worldwide. Recently, the infection has been associated with adverse outcomes of pregnancy and increased risks of HIV acquisition and transmission, as well as an association with cervical and prostate cancers. The consequences of trichomoniasis are likely much greater than previously recognized, both at the individual and the community level. Since many cases are asymptomatic, and the most common approach used for diagnosis (wet mount) is also one of the least sensitive, millions of T. vaginalis infections remain undiagnosed and therefore untreated. The purpose of this review is to address what is known about the treatment of T. vaginalis infections and what additional approaches could be pursued. The increasing recognition of the potential public health implications of trichomoniasis has resulted in greater attention to improving effectiveness of the interventions for affected individuals. Currently, treatment relies almost solely on one class of drugs, the 5- nitroimidazoles, which causes concern should widespread drug resistance arise. There are also concerns regarding which 5-nitroimidazole to use as not all of them are active against T. vaginalis. Finally, new therapeutic targets and active compounds with treatment potential are considered. PMID- 27697045 TI - Bacterial Labionin-Containing Peptides and Sactibiotics: Unusual Types of Antimicrobial Peptides with Potential Use in Clinical Settings (a Review). AB - One of the biggest challenges faced presently by clinicians is the emergence of multidrug -resistant pathogens that can infect humans and animals. To control the infections caused by such pathogens the development of new drugs is required. Bacteria are a rich source of ribosomally -synthesized antimicrobial peptides known as bacteriocins, which are characterized by the presence of a self-defense immunity system. Labionin-containing lantibiotics and sactibiotics are posttranslationally modified bacteriocins with peculiar features. Labionin containing peptides belong to subclass Ic lantibiotics in which the carbacyclic triamino triacid labionin, a structural variant of lanthionine, and a methyl substitute labionin derivative are found, giving the molecule a labyrinthine structure. Sactibiotics are circular or linear peptides belonging to a distinct bacteriocin class (class V) which is characterized by the presence of cross linkages formed by the thiol group of cysteine residues and the alpha-carbon of acceptor amino acids. A few examples of these bacteriocins have been described in the literature to date, although putative gene clusters with the potential to encode such peptides can be found in the genome of many bacterial species. Some peptides already under study exhibit potential biotechnological applications because of their remarkable antibacterial or antiviral activities, as well as their analgesic activity. Therefore, in this review, the main findings concerning these peptides will be addressed and discussed, with an emphasis on their potential use in clinical settings. PMID- 27697047 TI - Hybrid Compounds as Anti-infective Agents. AB - Hybrid drugs are multi-target chimeric chemicals combining two or more drugs or pharmacophores covalently linked in a single molecule. In the field of anti infective agents, they have been proposed as a possible solution to drug resistance issues, presumably having a broader spectrum of activity and less probability of eliciting high level resistance linked to single gene product. Although less frequently explored, they could also be useful in the treatment of frequently occurring co-infections. Here, we overview recent advances in the field of hybrid antimicrobials. Furthermore, we discuss some cutting-edge approaches to face the development of designed multi-target agents in the era of omics and big data, namely analysis of gene signatures and multitask QSAR models. PMID- 27697046 TI - Repurposing of Anticancer Drugs for the Treatment of Bacterial Infections. AB - Despite the fact that bacterial infections are one of the leading causes of death worldwide and that mortality rates are increasing at alarming rates, no new antibiotics have been produced by the pharmaceutical industry in more than a decade. The situation is so dire that the World Health Organization warned that we may enter a "post-antibiotic era" within this century; accordingly, bacteria resistant against all known antibiotics are becoming common and already producing untreatable infections. Although several novel approaches to combat bacterial infections have been proposed, they have yet to be implemented in clinical practice. Hence, we propose that a more plausible and faster approach is the utilization of drugs originally developed for other purposes besides antimicrobial activity. Among these are some anticancer molecules proven effective in vitro for eliminating recalcitrant, multidrug tolerant bacteria; some of which also protect animals from infections and recently are undergoing clinical trials. In this review, we highlight the similarities between cancer cells/tumors and bacterial infections, and present evidence that supports the utilization of some anticancer drugs, including 5-fluorouracil (5-FU), gallium (Ga) compounds, and mitomycin C, as antibacterials. Each of these drugs has some promising properties such as broad activity (all three compounds), dual antibiotic and antivirulence properties (5-FU), efficacy against multidrug resistant strains (Ga), and the ability to kill metabolically dormant persister cells which cause chronic infections (mitomycin C). PMID- 27697048 TI - Hybrid Compounds as Direct Multitarget Ligands: A Review. AB - Molecular Hybridization is an approach in rational drug design where new chemical entities are obtained by combining two or more pharmacophoric units from different bioactive compounds into a single molecule. Through this approach, medicinal chemists hope that the new hybrid derivative presents: better affinity and efficacy when compared to the parent drugs; a modified selectivity profile with improvement over pharmacokinetic and pharmacodynamic restrictions; dual or multiple modes of action; reduction of undesirable side effects; decreases in drug-drug interactions; reduced emergence or spread of drug resistance in microorganisms and protozoans; and lower cost. The approach has been successfully used by many research groups around the world and has had very promising results with diseases having multifactorial profiles, like Alzheimer's, Parkinson's disease, cancer, inflammation, and hypertension among others. The purpose of this paper is to conduct an updated review of molecular hybridization and multitarget profiling (a rational drug design approach), and its applications to the design and discovery of novel hybrid compounds with anti-inflammatory, antimicrobial, anticancer and antiprotozoal (leishmaniasis, malaria, and schistosomiasis) activities over the last six years. PMID- 27697049 TI - Macrolide Hybrid Compounds: Drug Discovery Opportunities in Anti- Infective and Anti-inflammatory Area. AB - Macrolides, polyketide natural products, and their 15-membered semi-synthetic derivatives are composed of substituted macrocyclic lactone ring and used primarily as potent antibiotics. Recently their usefulness was extended to antimalarial and anti-inflammatory area. Hybrid macrolides presented in this article are the next generation semi-synthetic compounds that combine pharmacophores from antibacterial, antimalarial and anti-inflammatory area with 14- and 15-membered azalide scaffolds. Antibacterial azalide hybrids with sulphonamides showed improved activity against resistant streptococci while quinolone conjugates demonstrated full coverage of respiratory pathogens including macrolide resistant strains and their efficacy was confirmed in mouse pneumonia model. Antimalarial macrolide hybrids, mainly involving (chloro)quinoline pharmacophores, showed outstanding activity against chloroquine resistant strains, favourable pharmacokinetics, promising in vivo efficacy as well as encouraging developmental potential. Anti-inflammatory hybrids were obtained by combining macrolides with corticosteroid and non-steroidal anti inflammatory drugs. They were found active in in vivo animal models of locally induced inflammation, asthma, inflammatory bowel disease and rheumatoid arthritis and demonstrated improved safety over parent steroid drugs. Overall, macrolide hybrids possess significant potential to be developed as potent novel medicines in therapeutic areas of utmost pharmaceutical interest. PMID- 27697050 TI - Hybrid Compounds as Multitarget Directed Anticancer Agents. AB - Cancer is a multifactorial disease including interactions of complex genetic and environmental factors. Clinical efficacy of anticancer chemotherapies is hampered by various factors including multidrug resistance (MDR). There is a strong need to discover more potent novel cancer drugs to kill cancer cells selectively. The recent new strategy for cancer treatment involves the design and synthesis of hybrid compounds as multitargeted anticancer agents. In this review, we focus on studies using hybrid compounds which were designed and synthesized from two or more different bioactive moieties conjugating them into a single hybrid drug. Hybrid compounds having more than a single target have been considered as more efficient and potent anticancer agents, since it is almost impossible to destroy cancer cells with a single target. Hybrid compounds overcome many disadvantages of single cancer drugs such as low solubility, adverse effects, and multi drug resistance. We have compiled the data of recent studies using the new hybrid anticancer drugs in cancer treatment. Thus, the design, synthesis and clinical trials of new hybrid compounds should be continued and supported in future. Results of recent studies have proved that they have a great potential to be used as novel anticancer drugs. PMID- 27697051 TI - Hybrid Drugs as Potential Combatants Against Drug-Resistant Microbes: A Review. AB - Antimicrobial resistance to drugs is a serious threat to public health. Different strategies have been adopted to deal with antimicrobial resistance to known drugs, one such strategy is the use of drug hybrids; this is a promising strategy to address the growing problem of drug resistance. The present review covers the very recent examples of combining (hybrid) two standard drugs in a single molecule for combating antibiotic-resistant microorganisms, and to present evidence supporting that drug hybrids are the urgent and practical solution to stop or slow down the spread of drug resistance. In addition, this review provides a literature overview of antimicrobial hybrids of standard drugs and their impact on antimicrobial resistance, covering publications between 2015 and 2016. PMID- 27697052 TI - Novel Multitarget Hybrid Compounds for the Treatment of Alzheimer's Disease. AB - Alzheimer's disease (AD) is the most prevalent among the aging diseases known as neurodegenerative disorders. Drug design programs over the last two decades were mainly based on the cholinergic, the amyloid or the tau hypothesis. However, none of the new drugs have a real impact on the outcome of the disease. The complex nature of AD has led to new approaches for drug development programs, the multitarget drug design hypothesis. Based on this hypothesis, the generation of multitarget hybrid compounds from previously known active molecules has been one of the most widely used to obtain new candidates for the future treatment of AD. Here, we summarize recent developments based on the hybridization hypothesis to obtain a potential clinical candidate for AD. PMID- 27697053 TI - Nitric Oxide-NASIDS Donor Prodrugs as Hybrid Safe Anti-inflammatory Agents. AB - Selective inhibition of cyclooxygenase-2 (COX-2) isozyme afforded a useful drug design concept that resulted in the development of effective anti-inflammatory drugs that are devoid of adverse side effects, in particular gastrointestinal irritation, ulcerogenicity and renal toxicity attributed to inhibition of the cytoprotective cyclooxygenase-1 (COX-1) isozyme. Unfortunately, some selective COX-2 inhibitory drugs such as rofecoxib and valdecoxib are believed to be responsible for cardiovascular complications. Nitric oxide (NO) is an effective vasodilator that also inhibits platelet aggregation. Therefore hybrid NSAIDs containing NO-donor moieties have been developed to obtain effective treatment of inflammation with reduced GI and cardiovascular side effects. Here we review some of the most promising recent advances in NO-NAISDs donor drug development and summarizes medicinal chemistry efforts in search for new NO-NSAIDs prodrugs in an attempt to pave the way for further development in this promising area of research. PMID- 27697054 TI - Novel Hybrid Anticonvulsants Derived from Pyrrolidine-2,5-dione Scaffold with Broad Spectrum of Activity in the Preclinical Studies. AB - The multifunctional ligands application is an emerging approach in drug delivery, mainly in the treatment of diseases with complex pathology, such as Alzheimer's, cancer, and epilepsy. Using this method many biomolecules with different properties are combined to form a single unit that can provide a complex broad spectrum activity. Thus, a new type of hybrid anticonvulsants based on the pyrrolidine-2,5-dione frame are detailed with the aim of acquiring more effective antiepileptic drugs (AED) that could suppress various human convulsions. These hybrid molecules attach to the chemical particles of clinically relevant AEDs such as ethosuximide, levetiracetam, and lacosamide. As a result of this hybridization process the compounds obtained were effective in three most important animal epilepsy models, namely the maximal electroshock seizure (MES) test, the subcutaneous pentylenetetrazole (scPTZ) test, and the six-Hertz (6 Hz) model in mice. These substances displayed wider spectrum of protection, more potent efficacy, and better safety profile than the aforementioned AEDs. Several compounds were also active in the formalin model of persistent pain in mice. The in vitro ligand binding studies have proved that the most conceivable molecular mechanism of anticonvulsant and antinociceptive action was the influence on the neuronal voltage-sensitive sodium and L-type calcium channels. PMID- 27697055 TI - Multitarget Tacrine Hybrids with Neuroprotective Properties to Confront Alzheimer's Disease. AB - Alzheimer's disease (AD) is a multifactorial neurodegenerative disorder. Several hallmarks such as beta-amyloid (Abeta) aggregation underlying amyloid plaque formation, tau-hyperphosphorylation leading to production of neurofibrillary tangles, and decline in the number of cholinergic neurons appear to be fundamental in the pathophysiology of the disease. Other evidence points also to the involvement of oxidative stress, biometal dyshomeostasis, inflammation, and cell cycle regulatory failure. Taking into account such premises, many attractive targets for the development of anti-AD drugs have emerged. Specifically, the multifactorial nature of AD calls for multi-target-directed ligands (MTDLs) which can be beneficial by providing interactions with multiple targets. Tacrine (THA), the first clinically effective acetylcholinesterase inhibitor, was approved for the treatment of mild to moderate AD. Unfortunately, frequent adverse effects including peripheral cholinergic effects and hepatotoxicity limited its therapeutic potential. Based on the numerous biological systems involved in AD progression, this review covers THA-incorporated hybrids possessing a neuroprotective profile. In particular, it focuses on THA hybrids capable of scavenging reactive oxygen species (ROS), and derivatives which reduce the formation of Abeta-plaques either directly by confronting the Abeta1-42 selfaggregation process or indirectly by inhibiting the BACE-1 enzyme or AChE induced Abeta1-40 aggregation. Particular interest is also addressed to THA hybrids with suppressed hepatotoxicity. PMID- 27697040 TI - Pharmacological Tools to Activate Microglia and their Possible use to Study Neural Network Patho-physiology. AB - BACKGROUND: Microglia are the resident immunocompetent cells of the CNS and also constitute a unique cell type that contributes to neural network homeostasis and function. Understanding microglia cell-signaling not only will reveal their diverse functions but also will help to identify pharmacological and non pharmacological tools to modulate the activity of these cells. METHODS: We undertook a search of bibliographic databases for peer-reviewed research literature to identify microglial activators and their cell-specificity. We also looked for their effects on neural network function and dysfunction. RESULTS: We identified several pharmacological targets to modulate microglial function, which are more or less specific (with the proper control experiments). We also identified pharmacological targets that would require the development of new potent and specific modulators. We identified a wealth of evidence about the participation of microglia in neural network function and their alterations in pathological conditions. CONCLUSION: The identification of specific microglia activating signals provides experimental tools to modulate the activity of this heterogeneous cell type in order to evaluate its impact on other components of the nervous system, and it also helps to identify therapeutic approaches to ease some pathological conditions related to microglial dysfunction. PMID- 27697056 TI - Dual-acting of Hybrid Compounds - A New Dawn in the Discovery of Multi-target Drugs: Lead Generation Approaches. AB - Finding high quality beginning compounds is a critical job at the start of the lead generation stage for multi-target drug discovery (MTDD). Designing hybrid compounds as selective multitarget chemical entity is a challenge, opportunity, and new idea to better act against specific multiple targets. One hybrid molecule is formed by two (or more) pharmacophore group's participation. So, these new compounds often exhibit two or more activities going about as multi-target drugs (mtdrugs) and may have superior safety or efficacy. Application of integrating a range of information and sophisticated new in silico, bioinformatics, structural biology, pharmacogenomics methods may be useful to discover/design, and synthesis of the new hybrid molecules. In this regard, many rational and screening approaches have followed by medicinal chemists for the lead generation in MTDD. Here, we review some popular lead generation approaches that have been used for designing multiple ligands (DMLs). This paper focuses on dual- acting chemical entities that incorporate a part of two drugs or bioactive compounds to compose hybrid molecules. Also, it presents some of key concepts and limitations/strengths of lead generation methods by comparing combination framework method with screening approaches. Besides, a number of examples to represent applications of hybrid molecules in the drug discovery are included. PMID- 27697057 TI - Multi-Target Directed Indole Based Hybrid Molecules in Cancer Therapy : An Up-To Date Evidence-Based Review. AB - Cancer is a multifactorial disease and most of its types still remain incurable, in spite of enormous efforts to explicate various tumor pathophysiology. The anti cancer drug discovery paradigm "one-compound-one-target" has failed and subsequently shifted to two-drug cocktail and recently the "multi-target approach" in order to design and develop agents able to act simultaneously on multiple intracellular constituents and signaling pathways. Novel hybrid compounds are now designed by incorporating two covalently linked independently acting pharmacores, each efficient at combating cancer. They can deliver synergistic effects from the dual action of both independently acting moieties by interacting with multiple targets. These composite molecules are also less prone to drug resistance, leading to an improved pharmacological potency than each individual moiety. As indole nucleus is a central component of many natural and synthetic molecules with extensive biological activity, this review incorporates a variety of such hybrid compounds with indole moiety as one of the active units, where better therapeutic effect has been successfully achieved, by either simultaneous or sequential action of individual functional pharmacore. The current limitations and challenges encountered in the development of these hybrid agents are also discussed. PMID- 27697058 TI - Multi-targeting Andrographolide and its Natural Analogs as Potential Therapeutic Agents. AB - Andrographis paniculata (A. paniculata) is a medicinal plant used in the Indian and Chinese traditional medicinal systems for its various beneficial properties of therapeutics. This is due to the presence of a diterpene lactone called 'andrographolide'. Several biological activities like antiinflammatory, antitumour, anti-hyperglycaemic, anti-fertility, antiviral, cardio protective and hepatoprotective properties are attributed to andrographolide and its natural analogs. The studies have shown that not only this diterpene lactone (andrographolide), but also other related terpenoid analogs from A. paniculata could be exploited for disease prevention due to their structural similarity with diverse pharmacological activities. Several scientific groups are trying to unveil the underlying mechanisms involved in these biological actions brough aout by andrographolide and its analogs. This review aims at giving an overview on the therapeutical and/or pharmacological activities of andrographolide and its derivatives and also exemplify the underlying mechanisms involved. PMID- 27697059 TI - Novel Structural Hybrids on the Base of Benzofuroxans and Furoxans. Mini-Review. AB - Hybrid drug strategy is based on the combination of two or more pharmacophores into a new chemical entity to improve the properties of the original compounds or to obtain double action of resulting molecule. Hybrid molecules, comprised of some pharmacophore and nitric oxide (NO) donor moiety, constitute one of the more promising approaches for the design of drugs. Furoxans and benzofuroxans are considered NO releasing prodrugs and are of great interest for researchers. In this review we will focus on furoxan and benzofuroxan hybrids described in literature during the last years (from 2005 to 2016). PMID- 27697060 TI - Prediction of Anti-Diabetic Drugs as Dual Inhibitors Against Acetylcholinesterase and Beta-Secretase: A Neuroinformatics Study. AB - An increasing number of research evidences indicate linkage between type 2 diabetes mellitus (T2DM) and Alzheimer's disease (AD); the two most common diseases of aging. In addition, T2DM and AD also share some common pathophysiological features. Therefore, dual therapy that targets both the diseases can be regarded as a beneficial approach. Acetylcholinesterase (AChE) and beta-secretase (BACE) have been considered as potential therapeutic targets for AD. Accordingly, the piece of work presented here describes the binding of anti-diabetic drugs (Jardiance, Suiny and Nesina) with AChE and BACE so as to further investigate connecting bridges concerning the treatment of these two diseases. We have used "Autodock 4.2" for docking experiments. Both, hydrogen bond and hydrophobic interactions were found to be involved in the proper positioning of these diabetic drugs within the catalytic site (CAS) of AChE and BACE enzymes to permit docking. Free energy of binding (DeltaG) for 'Jardiance AChE', 'uiny-AChE' and 'Nesina-AChE' CAS interactions were found to be -9.21, 7.32 and -10.66 kcal/mol, respectively; while for 'Jardiance-BACE', 'Suiny -BACE' and 'Nesina-BACE' CAS interactions the same were determined to be -8.91, -8.58 and -10.40 kcal/mol, respectively. Hence, these diabetic drugs might act as potent dual inhibitors for the treatment of diabetes-associated neurological disorders. Consequently, the results described herein may form the basis of future dual therapy against the same. PMID- 27697061 TI - Therapeutic Noninvasive Brain Stimulation in Alzheimer's Disease. AB - Alzheimer's disease (AD) is a looming public health crisis that currently lacks an effective treatment. Noninvasive Brain Stimulation (NBS), particularly transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS), offers a promising alternative approach to pharmacological interventions for an increasing number of neurological and psychiatric conditions. The aim of this review is summarize data from therapeutic trials of NBS in AD and other dementing illnesses. Despite the potential of NBS, there is limited theoretical framework and a lack of guidelines for its applications to AD. Several published clinical trials failed to report key parameters of the interventions thus limiting the utility of the study to assess efficacy and safety. Our review concludes with some suggestions for future studies aimed to advance research into NBS as a potential treatment for the symptoms and disabilities caused by AD and to enable comparison of results across trials. Ultimately, appropriately powered, and controlled, multi-site randomized clinical trials will be needed to evaluate the therapeutic potential of NBS in AD. PMID- 27697062 TI - Beyond Acetylcholinesterase Inhibitors: Novel Cholinergic Treatments for Alzheimer's Disease. AB - The major components of the cholinergic receptor system of the human brain include projections from the basal forebrain nuclei, and utilize the two types of receptors that they synapse on, nicotinic and muscarinic acetylcholine receptors. With the widespread cortical and subcortical projections of the basal forebrain, activity of these two receptor systems provide modulation of neurotransmitter activity underlying normal cognitive processes, such as attention, episodic memory, and working memory. Alzheimer's disease (AD) targets and damages cholinergic neurons in the basal forebrain, and as these projections are lost, cognitive performance progressively declines. Currently, the most widely prescribed treatment for AD is acetylcholinesterase inhibitor medications, which work by partially blocking the degradation of acetylcholine in the synapse and enabling more of the neurotransmitter to reach and activate cholinergic receptors. However since these medications have limited effectiveness, alternate treatments that focus on augmenting the activity of the receptors themselves, independent of acetylcholinesterase inhibition, are being explored. This review will discuss: 1) the role of the cholinergic system in modulating cognition, 2) novel cholinergic treatment strategies for AD-related cognitive decline, in particular treatments intended to increase cholinergic system activity by selectively targeting muscarinic and nicotinic acetylcholinergic receptors to improve cognitive performance, 3) risks, and additional considerations for cholinergic cognitive treatments for AD. PMID- 27697065 TI - Gender Disparity in Lipid Target Achievements in High and Very High Atherosclerotic Cardiovascular Disease Risk Patients in the Arabian Gulf. AB - BACKGROUND: Few studies assessed gender disparity in lipid goal attainment in the Arabian Gulf. Hence, we estimated gender gaps in lipid target achievements among patients at high and very high atherosclerotic cardiovascular disease (ASCVD) risk in the Centralized Pan-Middle East Survey on the undertreatment of hypercholesterolemia (CEPHEUS). METHODS: The study (conducted between November 22, 2009 and July 7, 2010) included 4,384 patients (≥18 years) on lipid lowering drugs at high and very ASCVD risk status from outpatient clinics of 177 specialists and primary care physicians in 6 Arabian Gulf countries. RESULTS: The overall mean age was 57+/-11 years and 40% (n=1763) were women. Women were more likely to have diabetes mellitus (84 vs 71%; p <0.001) and metabolic syndrome (49 vs 35%; p <0.001) compared with males. Women were less likely to achieve their low-density lipoprotein cholesterol (LDLC) (28 vs 32%; p = 0.002), high-density lipoprotein cholesterol (HDL-C) (42 vs 50%; p <0.001), and apolipoprotein B (Apo B) (38 vs 42%; p = 0.015) targets compared with men. In the very high ASCVD risk cohort, women were significantly less likely to achieve their LDL-C (20 vs 30%; p <0.001), non- HDL-C (34 vs 39%; p = 0.001) and Apo B (34 vs 41%; p <0.001) therapeutic targets compared with men. CONCLUSION: Women in the Arabian Gulf were less likely to achieve their lipid targets than men. The difference was more significant in the very high ASCVD risk group. PMID- 27697063 TI - Primary and Secondary Prevention Trials in Alzheimer Disease: Looking Back, Moving Forward. AB - The field of Alzheimer disease (AD) prevention has been a culmination of basic science, clinical, and translational research. In the past three years since the new 2011 AD diagnostic guidelines, large-scale collaborative efforts have embarked on new clinical trials with the hope of someday preventing AD. This review will shed light on the historical and scientific contexts in which these trials were based on, as well as discuss potential challenges these trials may face in the coming years. Primary preventive measures, such as lifestyle, multidomain, medication, and supplemental interventions, will be analyzed. Secondary prevention as represented by disease-modifying interventions, such as antiamyloid therapy and pioglitazone, will also be reviewed. Finally, hypotheses on future directions for AD prevention trials will be proposed. PMID- 27697066 TI - Renal Function Impairment in Patients Undergoing Elective EVAR vs. Elective Open Repair During Follow up Period: A Systematic Review of the Literature. AB - BACKGROUND: Endovascular (EVAR) or open surgical (OSR) repair are current treatment options for abdominal aortic aneurysm (AAA). OBJECTIVE: To produce a systematic review comparing the impact of these 2 treatment options on renal function during mid- and long term follow up. METHODS: The MEDLINE, EMBASE and Cochrane databases and key references were searched. RESULTS: Six studies were included from 2000 to 2016, (4 retrospective and 2 RCT studies) reporting on 2,102 patients (54%; 1096 EVAR, 46%; 1006 OSR). The mean age in EVAR group ranged from 69.4 to 73.8 years (91% males), and in OSR group from 68 to 73.6 years (91% males). The data were too heterogeneous to perform a meta-analysis. All studies used GFR (Glomerular Filtration Rate) or estimated GFR (eGFR) to record renal function. The commonest risk factors were the presence of hypertension (77.5%), hyperlipidaemia (48.3%), coronary artery disease (42%) and smoking (37.8%). During follow up, new events of renal impairment (increase >20% in GFR) in EVAR patients and in OSR patients were 58 (5.3%) and 52 (5.2%), respectively. The mean GFR was decreased during follow up period in both types of the procedure. CONCLUSION: There is lack of definitive evidence to prove the superiority of OSR over EVAR regarding renal function in the post-operative follow up period. It appears that renal impairment may occur after both interventions. Further prospective research is needed to clarify the issue. PMID- 27697067 TI - Hypovitaminosis D is Associated with Endothelial Dysfunction in Patients with Metabolic Syndrome. AB - OBJECTIVES: Recent research has shown that hypovitaminosis D may increase the risk of hypertension, vascular disease, diabetes mellitus, obesity and Metabolic Syndrome (MetS). Endothelial Dysfunction (ED) is one of the key components of MetS which is associated with an imbalance between vasoactive substances such as Nitric Oxide (NO) and Endothelins (ET). In this study, we assessed the association of 25(OH) D3 level with endothelial dysfunction and subclinical atherosclerosis in MetS patients. DESIGN AND METHODS: 105 MetS patients and 48 controls were included. 25(OH) D3 levels were measured using Ultra-High Performance Liquid Chromatography (UHPLC). NOx (NO2 plus NO3) and Endothelin- 1(ET-1) concentrations were determined along with routine biochemical tests. Flow Mediated Dilatation (FMD) and carotid Intima-Media Thickness (cIMT) were measured by ultrasonography. RESULTS: In MetS patients, vitamin D and NOx levels were significantly lower (p<0.001), while ET-1 levels were higher than controls (p<0.005). MetS patients with ED exhibited significantly lower vitamin D levels than their counterparts free of ED. Vitamin D levels were correlated positively with FMD and NOx, and negatively with systolic blood pressure and body mass index. Subclinical atherosclerosis as assessed by the cIMT did not associate with low vitamin D levels. CONCLUSION: Vitamin D deficiency seen in MetS patients is more prominent in the presence of ED. Hypovitaminosis D may affect endothelial cells, and participate in the development of hypertension. PMID- 27697068 TI - High-Density Lipoprotein and Low-Density Lipoprotein Subfractions in Patients with Chronic Kidney Disease. AB - BACKGROUND: Chronic Kidney Disease (CKD) is an independent risk factor for cardiovascular disease (CVD). CKD is accompanied by high cardiovascular mortality due to many factors, but atherosclerosis is thought to be a major cause at every CKD stage. It has been suggested that measuring and estimating changes in high density lipoprotein (HDL) and low density lipoprotein (LDL) subfractions may be important for predicting CVD in CKD patients. OBJECTIVE: The aim of this study was to determine and compare levels of HDL and LDL subfractions in patients with different CKD stages. METHODS: The study included 115 patients with CKD (CKD stage 2-25 patients, CKD stage 3-25; CKD stage 4-25 and CKD 5 undergoing dialysis - 40 patients) and 25 volunteers without CKD (control group). The Lipoprint System (Quantimetrix(r)) was used to analyse HDL and LDL subfractions. RESULTS: There were significant differences in the distribution of HDL1-HDL5 subfractions levels, which were significantly higher in patients with impaired renal function than in the control group (p<=.0.013 for all comparisons). HDL7-HDL10 subfractions were significantly more prevalent in healthy volunteers compared with CKD patients (p<=.0.001 for all comparisons). The analysis of LDL subfractions revealed significant differences only in IDL-B (p<0.05), IDL-A (p<0.05) and LDL2 (p<0.001) between patients with CKD stage 5 and controls. CONCLUSION: CKD influenced HDL and LDL subfractions. In CKD patients, large HDL subpopulations were more prevalent in contrast to small HDL subfractions in healthy subjects. Identification of patients with increased level of large HDL subfractions could be useful to identify CKD subjects at increased CV risk. Further studies with larger populations and with the application of a several methods of subfraction measurement are necessary to confirm these results. PMID- 27697069 TI - Kinase Inhibitor Indole Derivatives as Anticancer Agents: A Patent Review. AB - Cancer accounts for a number of deaths each year. Consequently, prevention of this deadly disease is more challenging and hence the invention of new anticancer agents is of utmost importance. The current review elaborates the importance of indole designs as patented in the form of anticancer druglike molecules targeting different cites of biological arena. Specific attention was given to kinases such as platelet-derived growth factor receptor, vascular endothelial growth factor receptor and fibroblast growth factor receptor, Bruton's tyrosine kinase, anaplastic lymphoma kinase, Janus kinase, cyclin-dependent kinase aurora kinases A, B and C, checkpoint kinases, protein kinase R, Pim kinases, phosphoinositide 3 kinase, altered proteins kinases, polo-like kinase and many more. Moreover, the article summarizes the mode of action through the particular functions of kinases and the inhibitory potential of indole derivatives toward specific kinase. Certain patents gathered in the existing review article suggest that indole core can be a versatile foundation to discover drug-like kinase inhibitor molecules and modification of substituents existing on the indole moiety may have important impact on the pharmacokinetic and pharmacodynamics aspects of the resultant scaffolds. The information presented here would gather a great deal of interest to identify the new molecular designs bearing indole nucleus presenting novel anticancer drugs with a wide variety of biological targets involved in cancer pathology focusing on the inhibition of tyrosine kinases, serine/threonine specific protein kinases, cyclin-dependent kinases, lipid kinases and altered protein kinases. PMID- 27697070 TI - Computational Approaches for Translational Oncology: Concepts and Patents. AB - BACKGROUND: Cancer is a heterogeneous disease, which is based on an intricate network of processes at different spatiotemporal scales, from the genome to the tissue level. Hence the necessity for the biomedical and pharmaceutical research to work in a multiscale fashion. In this respect, a significant help derives from the collaboration with theoretical sciences. Mathematical models can in fact provide insights into tumor-related processes and support clinical oncologists in the design of treatment regime, dosage, schedule and toxicity. OBJECTIVE AND METHOD: The main objective of this article is to review the recent computational based patents which tackle some relevant aspects of tumor treatment. We first analyze a series of patents concerning the purposing the purposing or repurposing of anti-tumor compounds. These approaches rely on pharmacokinetics and pharmacodynamics modules, that incorporate data obtained in the different phases of clinical trials. Similar methods are also at the basis of other patents included in this paper, which deal with treatment optimization, in terms of maximizing therapy efficacy while minimizing side effects on the host. A group of patents predicting drug response and tumor evolution by the use of kinetics graphs are commented as well. We finally focus on patents that implement informatics tools to map and screen biological, medical, and pharmaceutical knowledge. RESULTS AND CONCLUSIONS: Despite promising aspects (and an increasing amount of the relative literature), we found few computational-based patents: there is still a significant effort to do for allowing modelling approaches to become an integral component of the pharmaceutical research. PMID- 27697071 TI - An Evaluation of the Efficacy of Local Hemostatic Measures in Dental Patients Taking Oral Anticoagulants: A Critical Review of the Literature Over the Past Two Decades. AB - The increased risk of bleeding observed in patients on oral anticoagulant therapy (OAT) undergoing outpatient oral surgical procedures has been reported in the literature and remains a major concern in the care of these patients. This is still of great concern to dental surgeons that discontinuing OAT medication increases the risk of thromboembolism, while maintaining the therapeutic dose increases the risk of hemorrhage. Several local hemostatic measures have been used to control bleeding in patients on OAT. However, the effectiveness of these measures has not been thoroughly investigated. The aim of this study is to evaluate the efficacy of local hemostatic measures in patients taking oral anticoagulants. Various databases were searched using the key terms. Selection criteria included publications in English, Spanish, or Portuguese within the last 20 years. The titles and abstracts of papers were initially screened, and reports of 18 clinical trials were selected for a critical review and scored according to CONSORT 2010 guidelines. The data extracted from these trials represented 1821 patients receiving OAT, 4116 tooth extractions, and 144 cases of postoperative bleeding. In most studies, there were no differences in the effectiveness of various local hemostatic measures, and only tranexamic acid was proven effective as compared with a placebo group. The reported INR values varied widely among studies; the lowest INR value was 0.9 and the highest was 5.0. All local hemostatic methods showed low rates of bleeding; and when bleeding occurred, the use of these methods was essential for controlling postoperative bleeding. While local hemostatic measures appear to be effective in controlling postoperative bleeding, additional controlled randomized clinical trials are needed to assess the true effectiveness of these measures in patients taking OAT. PMID- 27697064 TI - Targeting Tumor Necrosis Factor Alpha for Alzheimer's Disease. AB - Alzheimer's disease (AD) affects an estimated 44 million individuals worldwide, yet no therapeutic intervention is available to stop the progression of the dementia. Neuropathological hallmarks of AD are extracellular deposits of amyloid beta (Abeta) peptides assembled in plaques, intraneuronal accumulation of hyperphosphorylated tau protein forming tangles, and chronic inflammation. A pivotal molecule in inflammation is the pro-inflammatory cytokine TNF-alpha. Several lines of evidence using genetic and pharmacological manipulations indicate that TNF-alpha signaling exacerbates both Abeta and tau pathologies in vivo. Interestingly, preventive and intervention anti-inflammatory strategies demonstrated a reduction in brain pathology and an amelioration of cognitive function in rodent models of AD. Phase I and IIa clinical trials suggest that TNF alpha inhibitors might slow down cognitive decline and improve daily activities in AD patients. In the present review, we summarize the evidence pointing towards a beneficial role of anti-TNF-alpha therapies to prevent or slow the progression of AD. We also present possible physical and pharmacological interventions to modulate TNF-alpha signaling in AD subjects along with their limitations. PMID- 27697072 TI - Morphometrical and Morphological Alterations of Human Leukocytes Exposed to 1.8 GHz Electromagnetic Radiations: In Vitro Protective Effects Induced by Polyphenols. AB - BACKGROUND: Our recent findings have demonstrated that electromagnetic radiations (EMR) (1.8 GHz radiofrequency) are able to in vitro induce morphometrical and morphological modifications of human leukocytes from normal donors. METHODS: In view of the evidence that polyphenols exert many beneficial effects on plants, animals and humans, leukocytes from human peripheral blood were pre-treated for 1 h with two polyphenol preparations from red grape before EMR exposure (1.8 GHz). RESULTS: Our data will show that polyphenol pre-treatment reverts to normality the morphology of irradiated leukocytes in comparison to irradiated cells only. Conversely, leukocyte morphometry seems to be not affected by this treatment. CONCLUSION: Here, we demonstrate that polyphenols are also able to normalize leukocyte morphology per se altered before as well as after irradiation. Finally, a working hypothesis aimed at clarifying the protective mechanisms exerted by polyphenols on irradiated leukocytes will be illustrated. PMID- 27697073 TI - Cigarette Smoke-mediated Perturbations of the Immune Response: A New Therapeutic Approach with Natural Compounds. AB - Cigarette smoke (CS) accounts for the outcome of several pathologies, even including lung cancer, cardiovascular disease and chronic obstructive pulmonary disease (COPD). Under healthy conditions, lung immune system becomes tolerant in response to various external stimuli. CS exposure alters the pulmonary immune equilibrium, thus leading to a condition of hyper activation of the local innate and adaptive immunity. COPD is one of the major complications of chronic CS exposure where a pro-inflammatory profile of the pulmonary and systemic immunity is predominant. In this review, alternative treatments with natural products to mitigate CS-mediated pulmonary inflammation are proposed. In particular, polyphenols, a class of natural compounds largely present in fruits and vegetables, have been shown to act as anti-inflammatory agents. Accordingly, recent experimental and clinical evidences support polyphenol-mediated potential health benefits in smokers. For instance, pomegranate juice is able to attenuate the damage provoked by CS on cultured human alveolar macrophages. In addition, maqui beery extract has been proven to normalize H2O2 and interleukin-6 levels in exhaled breath condensate in healthy smokers. However, some limitations of alternative treatments are represented by a better knowledge of the mechanism(s) of action exerted by polyphenols and by the lack of animal models of COPD. In any case, the potential targets of polyphenols in the course of COPD will be outlined with special reference to the activation of T regulatory cells as well as to the inhibition of the polymorphonuclear cell and monocyte respiratory burst and of the NF-kappaB pathway, respectively. PMID- 27697074 TI - 18F-FDG-PET Correlates of Impulse Control Disorder in a Diabetic Patient. AB - BACKGROUND: Studies have already shown that hyperglycemia and insulin resistance are significantly associated with the impairment of cerebral glucose metabolism that may secondary lead to cognitive disturbances. In this study, we aimed to evaluate the neurometabolic correlates of diabetes in a patient with Intermittent explosive disorder (IED). METHODS: We have investigated the cerebral glucose metabolism via 2-[18F]-fluoro-2- deoxy-D-glucose positron emission tomography (FDG-PET) in a diabetic patient with aggressive outbursts. RESULTS: We have found significantly reduced glucose uptake in left temporoparietal region, pontin area, and left nucleus lentiformis. DISCUSSION: Our present results indicate decreased cerebral glucose metabolism in specific cerebral cortical and subcortical areas. The main limitation of this report is that, this is a single case study and that these findings need to be replicated in well- conducted randomized controlled studies by using additional neuroquantitative methods. PMID- 27697075 TI - Sex Impact on Biomarkers, Pharmacokinetics and Pharmacodynamics. AB - Sex is one of several factors influencing pharmacological responses, but research on its effects on pharmacokinetics and pharmacodynamics, although emerging remarkably, remains poor and contains many methodological issues. In this review, the current state of knowledge about sex differences in pharmacokinetics and some hints to pharmacogenomics were evaluated. Moreover, considering that many pharmacological responses are monitored through biomarkers, the influence of sex on some biomarkers has been reported. Finally, we report sex differences in pharmacodynamics, particularly analysing opioids and their use during pregnancy, labor and breastfeeding. In conclusion, a more precise sex- and genderbased approach appears necessary to achieve more evidence-based therapy in men and women. PMID- 27697076 TI - Coffee: A Dietary Intervention on Type 2 Diabetes? AB - Coffee beverages, prepared in a multitude of ways around the world, are increasingly part of our daily lives. Although considered an unhealthy beverage for decades, coffee is increasingly the headline of medical journals in association with a reduced risk for several diseases. What if this beverage could give us pleasure, while modulating mood and lowering the risk for several diseases of the modern society, including type 2 diabetes (T2D)? Based on the most recent epidemiological and research data, long-term consumption of coffee beverages is associated with a lower risk of developing T2D in healthy individuals, probably involving multiple mechanisms, with interventions on glucose homeostasis, antioxidant activity, and inflammatory biomarkers. Several coffee constituents potentially responsible for these effects are described, as well as the factors that make their presence highly variable, with interesting effects associated with chlorogenic acids, trigonelline and norharman. Due to the high number of compounds contained in coffee, we explore the potential synergic effect within the coffee matrix. Moreover, acute coffee consumption shows different health effects from those achieved on a long-term daily consumption, and not all coffee beverages are similar. Still, despite the huge amount or work developed in the last decade, the substances and mechanisms behind these protective effects on T2D are still to be fully elucidated, being therefore soon for dietary interventions based on coffee. PMID- 27697077 TI - Medicinal Plants for Diabetes Treatment During Pregnancy. AB - Diabetes mellitus is a syndrome of great importance that affects an increasing number of people every day. In particular, diabetes is a common and important disease during pregnancy and is marked by complications, both fetal and maternal, that increase the risks of morbidity and mortality for diabetic pregnant women and their offspring. Drugs such as insulin and hypoglycemic drugs are given to treat diabetes, but regular exercise and adequate diet have also been indicated. Furthermore, coadjutant therapies such as medicinal plants are popularly used to reduce diabetes-induced hyperglycemia, either within or outside the context of pregnancy. However, studies examining plant use for diabetes treatment are necessary to confirm its possible effects and its safety for the mother and fetus. The objective of this literature review was to conduct a survey of plant species that are utilized worldwide and their stated therapeutic uses. A literature search was performed using the terms "diabetes and pregnancy", which resulted in the identification of 31,272 articles. Of these studies, only 12 (0.0038%) were related to medicinal plants, demonstrating that there has been little investigation into this issue. Of the papers analyzed in this review, half evaluated plant leaves, indicating that these scientific studies attempted to reproduce the preparations commonly used by various populations, i.e., in the form of tea. Additionally, more than 90% of studies utilized experimental animals to evaluate the maternal-fetal safety of medicinal plant substances that may potentially be dangerous for humans. Thus, once confidence levels for plant derived substances are established based on toxicological analyses and safety is confirmed, it is possible that plants will be used to complement conventional diabetes therapies. PMID- 27697079 TI - Resting-state brain alteration after a single dose of SSRI administration predicts 8-week remission of patients with major depressive disorder. AB - BACKGROUND: The present study investigated alteration of brain resting-state activity induced by antidepressant treatment and attempted to investigate whether treatment efficacy can be predicted at an early stage of pharmacological treatment. METHOD: Forty-eight first-episode medication-free patients diagnosed with major depression received treatment with escitalopram. Resting-state functional magnetic resonance imaging was administered prior to treatment, 5 h after the first dose, during the course of pharmacological treatment (week 4) and at endpoint (week 8). Resting-state activity was evaluated in the course of the 8 week treatment and in relation to clinical improvement. RESULTS: Escitalopram dynamically modified resting-state activity in depression during the treatment. After 5 h the antidepressant induced a significant decrease in the signal in the occipital cortex and an increase in the dorsolateral and dorsomedial prefrontal cortices and middle cingulate cortex. Furthermore, while remitters demonstrated more obvious changes following treatment, these were more modest in non responders suggesting possible tonic and dynamic differences in the serotonergic system. Changes after 5 h in the caudate, occipital and temporal cortices were the best predictor of clinical remission at endpoint. CONCLUSIONS: This study revealed the possibility of using the measurement of resting-state neural changes a few hours after acute administration of antidepressant to identify individuals likely to remit after a few weeks of treatment. PMID- 27697078 TI - Longitudinal alterations in motivational salience processing in ultra-high-risk subjects for psychosis. AB - BACKGROUND: Impairments in the attribution of salience are thought to be fundamental to the development of psychotic symptoms and the onset of psychotic disorders. The aim of the present study was to explore longitudinal alterations in salience processing in ultra-high-risk subjects for psychosis. METHOD: A total of 23 ultra-high-risk subjects and 13 healthy controls underwent functional magnetic resonance imaging at two time points (mean interval of 17 months) while performing the Salience Attribution Test to assess neural responses to task relevant (adaptive salience) and task-irrelevant (aberrant salience) stimulus features. RESULTS: At presentation, high-risk subjects were less likely than controls to attribute salience to relevant features, and more likely to attribute salience to irrelevant stimulus features. These behavioural differences were no longer evident at follow-up. When attributing salience to relevant cue features, ultra-high-risk subjects showed less activation than controls in the ventral striatum at both baseline and follow-up. Within the high-risk sample, amelioration of abnormal beliefs over the follow-up period was correlated with an increase in right ventral striatum activation during the attribution of salience to relevant cue features. CONCLUSIONS: These findings confirm that salience processing is perturbed in ultra-high-risk subjects for psychosis, that this is linked to alterations in ventral striatum function, and that clinical outcomes are related to longitudinal changes in ventral striatum function during salience processing. PMID- 27697080 TI - Evidence of leptospirosis in the kidneys and serum of feral swine (Sus scrofa) in the United States. AB - Leptospirosis is the most widespread zoonosis in humans worldwide. In the United States, widespread detection of antibodies to leptospirosis have been identified in feral swine (Sus scrofa) with the highest detection of serovars, Bratislava, Icterohaemorrhagiae, and Pomona. Over the past few years, feral swine populations have expanded their geographical range and distribution in the United States with reports in at least 39 of 50 states. Since feral swine serve as reservoirs for serovars that can infect humans, it is important to understand the risk of transmission. In order to learn more about the probability that feral swine shed infectious leptospires, we collected kidneys and paired serum when possible from 677 feral swine in 124 counties of 29 states. These counties had previously been identified as antibody positive for Leptospira interrogans serovars Bratislava, Canicola, Grippotyphosa, Hardjo, Icterohaemorrhagiae or Pomona. Although exposure to these same six serovars of leptospirosis continued to be high (53% overall) in the counties we sampled, we detected leptospiral DNA in only 3.4% of feral swine kidneys tested. Based on these results, it appears that although feral swine can serve as a source of infection to humans, especially in those who are more likely to encounter them directly such as wildlife biologists, veterinarians, and hunters, the risk may be relatively low. However, further studies to examine the relationship between leptospiral shedding in the urine and kidneys in addition to culturing the organism are recommended in order to better understand the risk associated with feral swine.

PMID- 27697082 TI - Prevalence, risk factors, and the desire for help of distressed newly diagnosed cancer patients: A large-sample study. AB - OBJECTIVE: Beginning in 2007, all newly diagnosed cancer patients at the Koo Foundation Sun Yat-Sen Cancer Center (KF-SYSCC) were screened for psychosocial distress. Our social workers, as part of the psychosocial care team (PCT), have engaged in proactive outreach with patients identified as distressed. The goal of the present study was to assess the prevalence of psychosocial distress and the extent of contact between the PCT and distressed patients. METHOD: Newly diagnosed patients who were treated at KF-SYSCC between 2007 and 2010 for cancer were eligible if there were at least 100 patients with the same type of cancer. Before treatment began, they were screened with the Pain Scale and the Distress Thermometer (DT) and had the option to specify a desire for help. The rates of distress were analyzed by cancer type and by probable related factors. Information regarding contact with the PCT was retrieved from computerized databases. RESULTS: Overall, some 5,335 cancer patients representing 12 major cancer types were included in our study. Of these, 1,771 (33.20%) were significantly distressed. By multivariate logistic regression, younger age, female gender, higher pain score, and disease stage, but not cancer type, were found to be associated with higher rates of distress. Among these distressed patients, 628 (36%) had some contact with the PCT. SIGNIFICANCE OF RESULTS: This Taiwanese study with a large sample size revealed a prevalence rate of psychosocial distress similar to rates found in Western countries. Contact with the PCT was established in only 36% of significantly distressed patients, despite a proactive outreach program. It is very important to have screening results made available in a timely fashion to the psycho-oncology team so that appropriate care can be offered promptly. PMID- 27697084 TI - Environmental Exposures and the Risk of Central Venous Catheter Complications and Readmissions in Home Infusion Therapy Patients. AB - BACKGROUND Patients are frequently discharged with central venous catheters (CVCs) for home infusion therapy. OBJECTIVE To study a prospective cohort of patients receiving home infusion therapy to identify environmental and other risk factors for complications. DESIGN Prospective cohort study between March and December 2015. SETTING Home infusion therapy after discharge from academic medical centers. PARTICIPANTS Of 368 eligible patients discharged from 2 academic hospitals to home with peripherally inserted central catheters and tunneled CVCs, 222 consented. Patients remained in the study until 30 days after CVC removal. METHODS Patients underwent chart abstraction and monthly telephone surveys while the CVC was in place, focusing on complications and environmental exposures. Multivariable analyses estimated adjusted odds ratios and adjusted incident rate ratios between clinical, demographic, and environmental risk factors and 30-day readmissions or CVC complications. RESULTS Of 222 patients, total parenteral nutrition was associated with increased 30-day readmissions (adjusted odds ratio, 4.80 [95% CI, 1.51-15.21) and CVC complications (adjusted odds ratio, 2.41 [95% CI, 1.09-5.33]). Exposure to soil through gardening or yard work was associated with a decreased likelihood of readmissions (adjusted odds ratio, 0.09 [95% CI, 0.01-0.74]). Other environmental exposures were not associated with CVC complications. CONCLUSIONS complications and readmissions were common and associated with the use of total parenteral nutrition. Common environmental exposures (well water, cooking with raw meat, or pets) did not increase the rate of CVC complications, whereas soil exposures were associated with decreased readmissions. Interventions to decrease home CVC complications should focus on total parenteral nutrition patients. Infect Control Hosp Epidemiol 2016;1-8. PMID- 27697085 TI - Poor stimulus discriminability as a common neuropsychological deficit between ADHD and reading ability in young children: a moderated mediation model. AB - BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is frequently associated with poorer reading ability; however, the specific neuropsychological domains linking this co-occurrence remain unclear. This study evaluates information-processing characteristics as possible neuropsychological links between ADHD symptoms and RA in a community-based sample of children and early adolescents with normal IQ (?70). METHOD: The participants (n = 1857, aged 6-15 years, 47% female) were evaluated for reading ability (reading single words aloud) and information processing [stimulus discriminability in the two-choice reaction-time task estimated using diffusion models]. ADHD symptoms were ascertained through informant (parent) report using the Development and Well Being Assessment (DAWBA). Verbal working memory (VWM; digit span backwards), visuospatial working memory (VSWM, Corsi Blocks backwards), sex, socioeconomic status, and IQ were included as covariates. RESULTS: In a moderated mediation model, stimulus discriminability mediated the effect of ADHD on reading ability. This indirect effect was moderated by age such that a larger effect was seen among younger children. CONCLUSION: The findings support the hypothesis that ADHD and reading ability are linked among young children via a neuropsychological deficit related to stimulus discriminability. Early interventions targeting stimulus discriminability might improve symptoms of inattention/hyperactivity and reading ability.

AB - We report on a quality improvement initiative for hand hygiene adherence using the patient-as-observer method in the ambulatory setting. There were 604,661 observations recorded with improvement of adherence from 88% to 95% or greater; alcohol-based hand sanitizer purchasing correlated with this increase. This sustainable method effectively ensures hand hygiene adherence. Infect Control Hosp Epidemiol 2016;1496-1498. PMID- 27697083 TI - Post-traumatic stress disorder and cardiometabolic disease: improving causal inference to inform practice. AB - Post-traumatic stress disorder (PTSD) has been declared 'a life sentence' based on evidence that the disorder leads to a host of physical health problems. Some of the strongest empirical research - in terms of methodology and findings - has shown that PTSD predicts higher risk of cardiometabolic diseases, specifically cardiovascular disease (CVD) and type 2 diabetes (T2D). Despite mounting evidence, PTSD is not currently acknowledged as a risk factor by cardiovascular or endocrinological medicine. This view is unlikely to change absent compelling evidence that PTSD causally contributes to cardiometabolic disease. This review suggests that with developments in methods for epidemiological research and the rapidly expanding knowledge of the behavioral and biological effects of PTSD the field is poised to provide more definitive answers to questions of causality. First, we discuss methods to improve causal inference using the observational data most often used in studies of PTSD and health, with particular reference to issues of temporality and confounding. Second, we consider recent work linking PTSD with specific behaviors and biological processes, and evaluate whether these may plausibly serve as mechanisms by which PTSD leads to cardiometabolic disease. Third, we evaluate how looking more comprehensively into the PTSD phenotype provides insight into whether specific aspects of PTSD phenomenology are particularly relevant to cardiometabolic disease. Finally, we discuss new areas of research that are feasible and could enhance understanding of the PTSD cardiometabolic relationship, such as testing whether treatment of PTSD can halt or even reverse the cardiometabolic risk factors causally related to CVD and T2D. PMID- 27697086 TI - Infection Prevention and Antimicrobial Stewardship Knowledge for Selected Infections Among Nursing Home Personnel. AB - OBJECTIVE To assess knowledge about infection prevention among nursing home personnel and identify gaps potentially addressable through a quality improvement collaborative. DESIGN Baseline knowledge assessment of catheter-associated urinary tract infection, asymptomatic bacteriuria, antimicrobial stewardship, and general infection prevention practices for healthcare-associated infections. SETTING Nursing homes across 14 states participating in the national "Agency for Healthcare Research and Quality Safety Program for Long-Term Care: Healthcare Associated Infections/Catheter-Associated Urinary Tract Infection." PARTICIPANTS Licensed (RNs, LPNs, APRNs, MDs) and unlicensed (clinical nursing assistants) healthcare personnel. METHODS Each facility aimed to obtain responses from at least 10 employees (5 licensed and 5 unlicensed). We assessed the percentage of correct responses. RESULTS A total of 184 (78%) of 236 participating facilities provided 1 response or more. Of the 1,626 respondents, 822 (50.6%) were licensed; 117 facilities (63.6%) were for-profit. While 99.1% of licensed personnel recognized the definition of asymptomatic bacteriuria, only 36.1% knew that pyuria could not distinguish a urinary tract infection from asymptomatic bacteriuria. Among unlicensed personnel, 99.6% knew to notify a nurse if a resident developed fever or confusion, but only 27.7% knew that cloudy, smelly urine should not routinely be cultured. Although 100% of respondents reported receiving training in hand hygiene, less than 30% knew how long to rub hands (28.5% licensed, 25.2% unlicensed) or the most effective agent to use (11.7% licensed, 10.6% unlicensed). CONCLUSIONS This national assessment demonstrates an important need to enhance infection prevention knowledge among healthcare personnel working in nursing homes to improve resident safety and quality of care.

AB - Signal peptide CUB EGF-like domain-containing protein 2 (SCUBE2), a member of the SCUBE family of proteins, was recently found to play an important role in cancer development. However, little is known regarding its biological function in glioma. In the present study, we investigated the effect of SCUBE2 on glioma and explored its relevant mechanisms. The study showed that SCUBE2 had a low expression in glioma tissue and cell lines. SCUBE2 overexpression inhibited glioma cell proliferation in vitro and in vivo as well as suppressed glioma cell migration and invasion in vitro. Furthermore, we found that the Sonic hedgehog (Shh) signaling pathway was involved in the inhibitory effect of SCUBE2 overexpression on glioma cells. In light of the results obtained from our study, SCUBE2 may be regarded as a potential therapeutic target for glioma. PMID- 27697089 TI - Human cysticercosis in Portugal: long gone or still contemporary? AB - Cysticercosis, a leading cause of acquired epilepsy in developing countries, has been controlled or eradicated in industrialized countries. This paradigm has recently been challenged, with human neurocysticercosis (NCC) being increasingly diagnosed in these countries. In order to assess the NCC burden in Portugal, a retrospective study on NCC hospitalizations (2006-2013) was conducted based on the national database on hospital morbidity: 357 hospitalized cases were detected. NCC was most frequent in the following age groups: 20-64 years (n = 197, 55.2%) >64 years (n = 111, 31.1%), and <20 years (n = 49, 13.7%). In the Norte and Centro regions cases tended to be older than in the Lisboa and Vale do Tejo Region. The results raise concerns for imported and autochthonous disease, suggesting the Lisboa and Vale do Tejo Region, due to its higher frequency of cases at younger ages, as a priority for research and intervention, and further suggest that NCC should be under surveillance (notifiable). The National Observatory of Cysticercosis and Taeniasis has been established and will define NCC cases as well as monitoring and surveillance. PMID- 27697088 TI - Neuropsychological Profile of Lifetime Traumatic Brain Injury in Older Veterans. AB - OBJECTIVES: The aim of this study was to characterize the neuropsychological profile of lifetime traumatic brain injury (TBI) in older Veterans. METHODS: Participants were 169 older Veterans [mean age=79.1 years (range, 51-97 years), 89% male, 92% Caucasian], 88 with lifetime TBI and 81 without TBI, living in Veterans' retirement homes in independent residence. TBI history was ascertained with the Ohio State TBI Identification Method structured interview. Cognition was assessed with neuropsychological tests: Raw scores were converted to Z-scores compared to age-corrected normative data and combined into five domain composite Z-scores (attention/working memory, learning/memory, language, processing speed, executive functioning). We investigated the association between TBI and performance in each cognitive domain in linear mixed effects models, with and without adjustment for demographics, medical comorbidities, and psychiatric variables. RESULTS: Compared to those without TBI, older Veterans with TBI had greater deficits in processing speed (estimate=-.52; p=.01; f 2=.08 in fully adjusted model) and executive functioning (estimate=-.41; p=.02; f 2=.06 in fully adjusted model) but performed similarly in the attention/working memory, learning/memory, and language domains (all p>.05). TBI-associated deficits were most prominent among individuals with multiple mild TBIs and those with any moderate-to-severe TBI, but were not clearly present among those with single mild TBI. CONCLUSIONS: The neuropsychological profile of lifetime TBI in older Veterans is characterized by slowed processing speed and executive dysfunction, especially among those with greater injury burden. This pattern may reflect long standing deficits or a TBI-associated cognitive decline process distinct from Alzheimer's disease. (JINS, 2017, 23, 56-64). PMID- 27697091 TI - Demethylation of Repressor Element-1 Silencing Transcription (REST) Suppresses the Malignant Phenotype of Breast Cancer via MMP9. AB - Breast cancer is the leading cause of cancer deaths in females all over the world, mainly resulting from metastasis. Previous studies have revealed that repressor element-1 (RE-1) silencing transcription (REST) acted as a tumor suppressor in breast cancer. However, the mechanism by which REST is regulated remains unknown, and its role in the metastasis in breast cancer cells remains unclear. In the present study, we showed that the expression of REST was lower in breast cancer samples than that of adjacent samples by immunohistochemical analysis, which may be due to hypermethylation of the REST promoter. Low REST levels are significantly associated with malignant progression in breast cancer patients. Additionally, we elucidated the functions of REST on proliferation and invasion in breast cancer cells. Lentivirus transfection was used to overexpress REST in human breast MDA-MB-231 cells. Then the biologic consequences of overexpressing REST in regard to cell proliferation, apoptosis, and invasion were determined. Furthermore, we also determined matrix metalloproteinase-9 (MMP9) as a target of REST. These results demonstrate that downregulation of REST, a tumor suppressor in breast cancer, is associated with hypermethylation. Induced REST expression is capable of attenuating invasion ability of breast cancer cells, which may be a novel strategy for metastatic breast cancer treatment. PMID- 27697092 TI - miR-935 Promotes Liver Cancer Cell Proliferation and Migration by Targeting SOX7. AB - Hepatocellular carcinoma (HCC) is the most common cancer in the world. MicroRNAs (miRNAs) are a type of small noncoding RNA that can regulate the expression of target genes under physiological and pathophysiological conditions. Aberrant expression of microRNA-935 (miR-935) has been reported in cancer studies. However, its expression and mechanism in HCC remain unclear. In our study, we found that miR-935 was upregulated in liver cancer tissues and cells. Overexpression of miR-935 in liver cells promoted cell proliferation, tumorigenesis, and cell cycle progression, whereas inhibition of miR-935 reduced cell proliferation, tumorigenicity, and cell cycle progression. These changes in the properties of HCC cells were associated with upregulation of two well-known cellular G1/S transitional regulators: cyclin D1 and c-Myc. Additionally, we identified SOX7 as a direct target of miR-935. Overexpression of miR-935 inhibited SOX7 expression but promoted the levels of c-Myc and cyclin D1, which promotes cell proliferation and tumorigenesis; knockdown of miR-935 increased SOX7 level and inhibited c-Myc and cyclin D1 expression, whereas SOX7 silencing could promote cell proliferation, cell motility, and invasiveness in vitro. Our findings suggest that miR-935 represents a biomarker and a potential new target in HCC progression by suppressing SOX7 expression. PMID- 27697093 TI - Knockdown of DDX46 Inhibits the Invasion and Tumorigenesis in Osteosarcoma Cells. AB - DDX46, a member of the DEAD-box (DDX) helicase family, is involved in the development of several tumors. However, the exact role of DDX46 in osteosarcoma and the underlying mechanisms in tumorigenesis remain poorly understood. Thus, in the present study, we explored the role of DDX46 in osteosarcoma and the underlying mechanisms. Our results demonstrated that the expression levels of DDX46 in both mRNA and protein were greatly elevated in human osteosarcoma tissues and cell lines. Knockdown of DDX46 obviously inhibited osteosarcoma cell proliferation and tumor growth in vivo. In addition, knockdown of DDX46 also significantly suppressed migration and invasion in osteosarcoma cells. Furthermore, knockdown of DDX46 substantially downregulated the phosphorylation levels of PI3K and Akt in SaOS2 cells. In summary, the present results have revealed that DDX46 plays an important role in osteosarcoma growth and metastasis. Knockdown of DDX46 inhibited osteosarcoma cell proliferation, migration, and invasion in vitro and tumor growth in vivo. Therefore, DDX46 may be a potential therapeutic target for the treatment of osteosarcoma. PMID- 27697094 TI - Determination of Withanolides in Withania somnifera by Liquid Chromatography: Single-Laboratory Validation, First Action 2015.17. AB - An LC method was developed and validated in 2007 for analyzing Withania somnifera raw material (root) and dried extracts for withanolide content, including withanoside IV, withanoside V, withaferin A, 12-deoxywithastromonolide, withanolide A, and withanolide B. The method involved the extraction of the analytes with methanol, their subsequent filtration, and then analysis on a C18 column with an acetonitrile gradient and UV detection. Single-laboratory validation yielded linearity generally in the range of 20 to 200 MUg/mL for each analyte, with a repeatability precision of RSD < 3% in most cases, and recovery in the range of 90 to 105%. These results compare well with the performance criteria recently detailed in AOAC Standard Method Performance Requirement 2015.007. The method was shown to be rugged with respect to different analysts, equipment, and days of analysis, and the sample solution was shown to be stable for 24 h at room temperature after extraction. The method was reviewed by the AOAC Expert Review Panel on Dietary Supplements (Set 2 Ingredients) and approved for First Action Official MethodSM status. PMID- 27697095 TI - MicroRNA-509-3p Inhibits Cancer Cell Proliferation and Migration via Upregulation of XIAP in Gastric Cancer Cells. AB - Gastric cancer (GC) is the fourth most common cancer globally. Recently, microRNAs (miRNAs) have been suggested to be closely associated with tumorigenesis. Aberrant expression of miR-509-3p has been reported in cancer studies. However, the expression and mechanism of its function in GC remain unclear. Here we showed that miR-509-3p was downregulated in GC specimens, which was associated with overall survival. Functional investigations demonstrated that the overexpression of miR-509-3p inhibited the migration and proliferation of the GC cells. Additionally, we identified X-linked inhibitor of apoptosis protein (XIAP) as a direct target of miR-509-3p. Knockdown of XIAP significantly attenuated the ability of proliferation, migration, and invasion of GC cells. The data therefore suggest that miR-509-3p plays an important role in the development and progression of GC, implicating possible applications in the clinic as a biomarker and a potential new target. PMID- 27697096 TI - Changes in Sexual Behavior of Orchidectomized Rats Under Influence of Allotransplantation of Testicular Interstitial Cell Suspension. AB - Transplantation of hormone-producing cells is an experimental endocrine dysfunction treatment. The present study investigated the effects of orchidectomy (OE) and transplantation of interstitial cell suspension (ICS) on rat sexual behavior. Adult experimental animals were divided into two populations. One of these populations had sexual experience before the experiment and the other did not. Each population was divided into three groups: control group and two orchidectomized groups. One of the orchidectomized groups was treated with ICS, and the other was treated with the vehicle. The changes in the sexual behavior were investigated on the following parameters: mount latency (ML), intromission latency (IL), ejaculation latency (EL), mount frequency (MF), intromission frequency (IF), copulatory efficacy (CE), and IF/EL ratio. The investigation of these changes lasted 4 weeks after ICS transplantation. The parameters of sexual behavior reflected a decrease in sexual function after OE at the beginning of the observation, especially for the animals that did not have a sexual experience. However, it was shown that sexual activity increased in the following 4 weeks. We have indicated that the loss of gonads attenuated the capacity to acquire sexual experience; nonetheless, it did not mean that the animals completely lost this capacity. Transplantation of ICS facilitated the maintenance of male sexual behavior after OE, fractionally enlarged the size of regressed seminal vesicles of the animals, and increased the free testosterone (T) level. These findings suggest the ICS can be considered as a temporal source of androgens, which can facilitate a restoration of sexual activity. PMID- 27697097 TI - Chromatographic Analysis of a Multicomponent Mixture of B1, B6, B12, Benfotiamine, and Diclofenac; Part I: HPLC and UPLC Methods for the Simultaneous Quantification of These Five Components in Tablets and Capsules. AB - New, simple, highly sensitive, precise, and accurate gradient reversed-phase chromatographic methods were developed using HPLC and ultra-HPLC (UPLC) systems for the determination of five components, namely thiamine, pyridoxine, cyanocobalamin, benfotiamine, and diclofenac in tablets and capsules. The methods were compared for their efficiency in the separation and determination of these five compounds using two different C18 columns (250 * 4.6 mm, 5 MUm; and 100 * 4.6 mm, 2.6 MUm) for HPLC and UPLC, respectively. Chromatographic separation was performed with a mobile phase containing acetonitrile and 0.025 M phosphate buffer (pH 3.5), with a gradient program and a flow rate of 1.5 and 1.0 mL/min for both methods, respectively. The methods were validated according to International Conference on Harmonization guidelines. Linearity was achieved in the range of 5.00 to 150.00 MUg/mL for each of the five compounds. Ruggedness and intermediate precision were confirmed by different analysts on different columns on different days. Moreover, the components were subjected to an accelerated stability study under acidic, alkaline, and oxidative stress conditions and no interfering peaks were observed. The five compounds were efficiently separated in <20 min by HPLC, whereas for UPLC, separation was achieved in <8 min, which dramatically decreased the consumption of organic solvents. PMID- 27697098 TI - High-Level Expression of RIPK4 and EZH2 Contributes to Lymph Node Metastasis and Predicts Favorable Prognosis in Patients With Cervical Cancer. AB - The investigation of specific genes will establish more useful biomarkers for accurate detection and management of gynecological cancers, especially patients with cervical cancer (CCP). The aim of this study was to evaluate the expression level of RIPK4 and EZH2 messenger RNA (RIPK4 and EZH2 mRNA) in CCP. Expression of RIPK4 and EZH2 in the tissues was determined by immunohistochemistry and qRT-PCR methods. Correlations of RIPK4 and EZH2 mRNA with clinical and pathological parameters were analyzed using the Fisher's exact test. The mRNA level of RIPK4 was significantly upregulated in tumor tissues compared with matched adjacent normal tissues (4.10 +/- 0.89 vs. 1.5 +/- 0.82; p = 0.021). EZH2 mRNA was increased in cancer tissues compared to normal tissues (3.54 +/- 0.71 vs. 1.2 +/- 0.65; p = 0.003). High expression of RIPK4 was observed in 25 patients (64.1%), whereas weak expression was seen in 14 cases (35.9%). Furthermore, the expression of RIPK4 was overexpressed in matched adjacent normal tissues (p = 0.004). FIGO stage and lymph node metastasis were significantly linked to a higher expression of RIPK4 (p < 0.05). Overexpression of EZH2 was found in 30 patients (76.9%) and was associated with FIGO stage, histological type, and lymph node metastasis (p < 0.05). In conclusion, our data suggest that RIPK4/EZH2 markers might be used as potential predictors of prognosis in cervical cancer. PMID- 27697099 TI - High TRAF6 Expression Is Associated With Esophageal Carcinoma Recurrence and Prompts Cancer Cell Invasion. AB - Esophageal cancer is one of the most common types of cancer, and it has a poor prognosis. The molecular mechanisms of esophageal cancer progression remain largely unknown. In this study, we aimed to investigate the clinical significance and biological function of tumor necrosis factor receptor-associated factor 6 (TRAF6) in esophageal cancer. Expression of TRAF6 in esophageal cancer was examined, and its correlation with clinicopathological factors and patient prognosis was analyzed. A series of functional and mechanism assays were performed to further investigate the function and underlying mechanisms in esophageal cancer. Expression of TRAF6 was highly elevated in esophageal cancer tissues, and patients with high TRAF6 expression have a significantly shorter survival time than those with low TRAF6 expression. Furthermore, loss-of-function experiments showed that knockdown of TRAF6 significantly reduced the migration and invasion abilities of esophageal cancer cells. Moreover, the pro-oncogenic effects of TRAF6 in esophageal cancer were mediated by the upregulation of AEP and MMP2. Altogether, our data suggest that high expression of TRAF6 is significant for esophageal cancer progression, and TRAF6 indicates poor prognosis in esophageal cancer patients, which might be a novel prognostic biomarker or potential therapeutic target in esophageal cancer.

AB - Cell therapy is not only a novel medical practice but also a medicinal product [cell therapy product (CTP)]. More and more CTPs are being approved for marketing globally because of the rapid development of biomedicine in cell culture, preservation, and preparation. However, regulation is the most important criterion for the development of CTPs. Regulations must be flexible to expedite the process of marketing for new CTPs. Recently, the Taiwan Food and Drug Administration (TFDA) updated the related regulations such as regulation of development, current regulatory framework and process, and the application and evaluation processes. When the quality of CTPs has been improved significantly, their safety and efficacy are further ensured. The treatment protocol, a new design for adaptive licensing to current clinical practice, is a rapid process for patients with life-threatening diseases or serious conditions for which there are no suitable drugs, medical devices, or other therapeutic methods available. The hospital can submit the treatment protocol to apply for cell therapy as a medical practice, which may result in easier and faster cell therapy development, and personalized treatment for individual patients will evolve quickly. PMID- 27697104 TI - Validation of the Applied Biosystems RapidFinder Shiga Toxin-Producing E. coli (STEC) Detection Workflow. AB - The Applied BiosystemsTM RapidFinderTM STEC Detection Workflow (Thermo Fisher Scientific) is a complete protocol for the rapid qualitative detection of Escherichia coli (E. coli) O157:H7 and the "Big 6" non-O157 Shiga-like toxin producing E. coli (STEC) serotypes (defined as serogroups: O26, O45, O103, O111, O121, and O145). The RapidFinder STEC Detection Workflow makes use of either the automated preparation of PCR-ready DNA using the Applied Biosystems PrepSEQTM Nucleic Acid Extraction Kit in conjunction with the Applied Biosystems MagMAXTM Express 96-well magnetic particle processor or the Applied Biosystems PrepSEQ Rapid Spin kit for manual preparation of PCR-ready DNA. Two separate assays comprise the RapidFinder STEC Detection Workflow, the Applied Biosystems RapidFinder STEC Screening Assay and the Applied Biosystems RapidFinder STEC Confirmation Assay. The RapidFinder STEC Screening Assay includes primers and probes to detect the presence of stx1 (Shiga toxin 1), stx2 (Shiga toxin 2), eae (intimin), and E. coli O157 gene targets. The RapidFinder STEC Confirmation Assay includes primers and probes for the "Big 6" non-O157 STEC and E. coli O157:H7. The use of these two assays in tandem allows a user to detect accurately the presence of the "Big 6" STECs and E. coli O157:H7. The performance of the RapidFinder STEC Detection Workflow was evaluated in a method comparison study, in inclusivity and exclusivity studies, and in a robustness evaluation. The assays were compared to the U.S. Department of Agriculture (USDA), Food Safety and Inspection Service (FSIS) Microbiology Laboratory Guidebook (MLG) 5.09: Detection, Isolation and Identification of Escherichia coli O157:H7 from Meat Products and Carcass and Environmental Sponges for raw ground beef (73% lean) and USDA/FSIS-MLG 5B.05: Detection, Isolation and Identification of Escherichia coli non-O157:H7 from Meat Products and Carcass and Environmental Sponges for raw beef trim. No statistically significant differences were observed between the reference method and the individual or combined kits forming the candidate assay using either of the DNA preparation kits (manual or automated extraction). For the inclusivity and exclusivity evaluation, the RapidFinder STEC Detection Workflow, comprising both RapidFinder STEC screening and confirmation kits, correctly identified all 50 target organism isolates and correctly excluded all 30 nontarget strains for both of the assays evaluated. The results of these studies demonstrate the sensitivity and selectivity of the RapidFinder STEC Detection Workflow for the detection of E. coli O157:H7 and the "Big 6" STEC serotypes in both raw ground beef and beef trim. The robustness testing demonstrated that minor variations in the method parameters did not impact the accuracy of the assay and highlighted the importance of following the correct incubation temperatures. PMID- 27697105 TI - Caffeine-induced food-avoidance behavior is mediated by neuroendocrine signals in Caenorhabditis elegans. AB - High-dose caffeine uptake is a developmental stressor and causes food-avoidance behavior (aversion phenotype) in C. elegans, but its mode of action is largely unknown. In this study, we investigated the molecular basis of the caffeineinduced aversion behavior in C. elegans. We found that aversion phenotype induced by 30 mM caffeine was mediated by JNK/MAPK pathway, serotonergic and dopaminergic neuroendocrine signals. In this process, the dopaminergic signaling appears to be the major pathway because the reduced aversion behavior in cat-2 mutants and mutants of JNK/MAPK pathway genes was significantly recovered by pretreatment with dopamine. RNAi depletion of hsp-16.2, a cytosolic chaperone, and cyp-35A family reduced the aversion phenotype, which was further reduced in cat-2 mutants, suggesting that dopaminergic signal is indeed dominantly required for the caffeine-induced food aversion. Our findings suggest that aversion behavior is a defense mechanism for worms to survive under the high-dose caffeine conditions. [BMB Reports 2017; 50(1): 31-36]. PMID- 27697106 TI - GPR78 promotes lung cancer cell migration and metastasis by activation of Galphaq Rho GTPase pathway. AB - GPR78 is an orphan G-protein coupled receptor (GPCR) that is predominantly expressed in human brain tissues. Currently, the function of GPR78 is unknown. This study revealed that GPR78 was expressed in lung cancer cells and functioned as a novel regulator of lung cancer cell migration and metastasis. We found that knockdown of GPR78 in lung cancer cells suppressed cell migration. Moreover, GPR78 modulated the formation of actin stress fibers in A549 cells, in a RhoA- and Rac1-dependent manner. At the molecular level, GPR78 regulated cell motility through the activation of Galphaq-RhoA/Rac1 pathway. We further demonstrated that in vivo, the knockdown of GPR78 inhibited lung cancer cell metastasis. These findings suggest that GPR78 is a novel regulator for lung cancer metastasis and may serve as a potential drug target against metastatic human lung cancer. [BMB Reports 2016; 49(11): 623-628]. PMID- 27697107 TI - C-terminally mutated tubby protein accumulates in aggresomes. AB - The tubby protein (Tub), a putative transcription factor, plays important roles in the maintenance and function of neuronal cells. A splicing defect-causing mutation in the 3'-end of the tubby gene, which is predicted to disrupt the carboxy-terminal region of the Tub protein, causes maturity-onset obesity, blindness, and deafness in mice. Although this pathological Tub mutation leads to a loss of function, the precise mechanism has not yet been investigated. Here, we found that the mutant Tub proteins were mostly localized to puncta found in the perinuclear region and that the C-terminus was important for its solubility. Immunocytochemical analysis revealed that puncta of mutant Tub co-localized with the aggresome. Moreover, whereas wild-type Tub was translocated to the nucleus by extracellular signaling, the mutant forms failed to undergo such translocation. Taken together, our results suggest that the malfunctions of the Tub mutant are caused by its misfolding and subsequent localization to aggresomes. [BMB Reports 2017; 50(1): 37-42]. PMID- 27697108 TI - Expression and characterization of transmembrane and coiled-coil domain family 3. AB - Transmembrane and coiled-coil domain family 3 (TMCC3) has been reported to be expressed in the human brain; however, its function is still unknown. Here, we found that expression of TMCC3 is higher in human whole brain, testis and spinal cord compared to other human tissues. TMCC3 was expressed in mouse developing hind brain, lung, kidney and somites, with strongest expression in the mesenchyme of developing tongue. By expression of recombinant TMCC3 and its deletion mutants, we found that TMCC3 proteins self-assemble to oligomerize. Immunostaining and confocal microscopy data revealed that TMCC3 proteins are localized in endoplasmic reticulum through transmembrane domains. Based on immunoprecipitation and mass spectroscopy data, TMCC3 proteins associate with TMCC3 and 14-3-3 proteins. This supports the idea that TMCC3 proteins form oligomers and that 14-3-3 may be involved in the function of TMCC3. Taken together, these results may be useful for better understanding of uncharacterized function of TMCC3. [BMB Reports 2016; 49(11): 629-634]. PMID- 27697109 TI - Epigenetic regulation of long noncoding RNA UCA1 by SATB1 in breast cancer. AB - Special AT-rich sequence binding protein 1 (SATB1) is a nuclear matrix-associated DNA-binding protein that functions as a chromatin organizer. SATB1 is highly expressed in aggressive breast cancer cells and promotes growth and metastasis by reprograming gene expression. Through genomewide cross-examination of gene expression and histone methylation, we identified SATB1 target genes for which expression is associated with altered epigenetic marks. Among the identified genes, long noncoding RNA urothelial carcinoma-associated 1 (UCA1) was upregulated by SATB1 depletion. Upregulation of UCA1 coincided with increased H3K4 trimethylation (H3K4me3) levels and decreased H3K27 trimethylation (H3K27me3) levels. Our study showed that SATB1 binds to the upstream region of UCA1 in vivo, and that its promoter activity increases with SATB1 depletion. Furthermore, simultaneous depletion of SATB1 and UCA1 potentiated suppression of tumor growth and cell survival. Thus, SATB1 repressed the expression of oncogenic UCA1, suppressing growth and survival of breast cancer cells. [BMB Reports 2016; 49(10): 578-583]. PMID- 27697110 TI - Oct4 resetting by Aurkb-PP1 cell cycle axis determines the identity of mouse embryonic stem cells. AB - In embryonic stem cells (ESCs), cell cycle regulation is deeply connected to pluripotency. Especially, core transcription factors (CTFs) which are essential to maintaining the pluripotency transcription programs should be reset during M/G1 transition. However, it remains unknown about how CTFs are governed during cell cycle progression. Here, we describe that the regulation of Oct4 by Aurora kinase b (Aurkb)/protein phosphatase 1 (PP1) axis during the cell cycle is important for resetting Oct4 to pluripotency and cell cycle related target genes in determining the identity of ESCs. Aurkb starts to phosphorylate Oct4(S229) at the onset of G2/M phase, inducing the dissociation of Oct4 from chromatin, whereas PP1 binds Oct4 and dephosphorylates Oct4(S229) during M/G1 transition, which resets Oct4-driven transcription for pluripotency and the cell cycle. Furthermore, Aurkb phosphormimetic and PP1 binding-deficient mutations in Oct4 disrupt the pluripotent cell cycle, lead to the loss of pluripotency in ESCs, and decrease the efficiency of somatic cell reprogramming. Based on our findings, we suggest that the cell cycle is directly linked to pluripotency programs in ESCs. [BMB Reports 2016; 49(10): 527-528]. PMID- 27697113 TI - Nutritional care of older patients: experiences of general practitioners and practice nurses. AB - Older people living in the community face unique nutritional issues that put them at risk of undernutrition, which is associated with increased morbidity and mortality. Primary healthcare staff such as general practitioners (GPs) and practice nurses (PNs) are well placed to identify nutritional problems early and intervene. The aim of this study was to understand the experiences and current practices in a sample of GPs and PNs with regards to nutritional care of elderly patients. An online survey of GPs and PNs working in regional Victoria was conducted. Among the 45 respondents, 89% reported encountering consultations with a nutritional component for older patients within the previous 3 months, and 94% of those took some action, most commonly referrals, dietary advice or prescribing supplements. Although the majority (63%) felt confident in providing appropriate nutritional recommendations for patients, 68% reported a desire for further professional development in the area. Given the frequency of nutritional issues presenting, further work is required to determine how well equipped primary healthcare staff are to provide nutritional advice to older patients. PMID- 27697112 TI - Polymer brush: a promising grafting approach to scaffolds for tissue engineering. AB - Polymer brush is a soft material unit tethered covalently on the surface of scaffolds. It can induce functional and structural modification of a substrate's properties. Such surface coating approach has attracted special attentions in the fields of stem cell biology, tissue engineering, and regenerative medicine due to facile fabrication, usability of various polymers, extracellular matrix (ECM) like structural features, and in vivo stability. Here, we summarized polymer brush-based grafting approaches comparing self-assembled monolayer (SAM)-based coating method, in addition to physico-chemical characterization techniques for surfaces such as wettability, stiffness/ elasticity, roughness, and chemical composition that can affect cell adhesion, differentiation, and proliferation. We also reviewed recent advancements in cell biological applications of polymer brushes by focusing on stem cell differentiation and 3D supports/implants for tissue formation. Understanding cell behaviors on polymer brushes in the scale of nanometer length can contribute to systematic understandings of cellular responses at the interface of polymers and scaffolds and their simultaneous effects on cell behaviors for promising platform designs.

AB - The human oral cavity contains a highly personalized microbiome essential to maintaining health, but capable of causing oral and systemic diseases. Thus, an in-depth definition of "healthy oral microbiome" is critical to understanding variations in disease states from preclinical conditions, and disease onset through progressive states of disease. With rapid advances in DNA sequencing and analytical technologies, population-based studies have documented the range and diversity of both taxonomic compositions and functional potentials observed in the oral microbiome in healthy individuals. Besides factors specific to the host, such as age and race/ethnicity, environmental factors also appear to contribute to the variability of the healthy oral microbiome. Here, we review bioinformatic techniques for metagenomic datasets, including their strengths and limitations. In addition, we summarize the interpersonal and intrapersonal diversity of the oral microbiome, taking into consideration the recent large-scale and longitudinal studies, including the Human Microbiome Project.

The treatment includes lowering of the blood triglyceride levels. We present a case of a 40-year-old woman who was admitted in this condition. She was treated with plasmapheresis, which led to a rapid decline of the blood triglyceride levels. The national Danish guidelines on treatment of acute pancreatitis do not mention plasmapheresis as a method of lowering elevated triglyceride levels. We suggest that the guidelines should be revised with attention to this treatment option. PMID- 27697119 TI - [Reversal strategies for non-vitamin K antagonist oral anticoagulants]. AB - Non-vitamin K oral anticoagulants (NOACs) are alternatives to vitamin K antagonists and provide consistent anticoagulation with equal or better clinical outcome and no need for routine monitoring. Bleeding is a feared complication of anticoagulants. Until recently, no specific agent has been available for reversal of NOACs. Idarucizumab binds dabigatran for rapid reversal of its activity without procoagulant effects. Andexanet alpha (expected release in 2016) and PER977 are antidotes under clinical development. This article summarizes current and potential future options to antagonize NOACs. PMID- 27697120 TI - [Oedematous malnutrition can also be seen in Danish children]. AB - We describe two children with oedematous malnutrition; one admitted to a nutrition unit in Uganda and another to a paediatric department in Denmark. Both children received nutritional therapy and recovered. Although oedematous malnutrition is rarely seen in industrialized countries, the condition has been associated with chronic diseases. It is a life-threatening condition, and the pathogenesis remains unknown. Specialized nutrition products have been developed for low-resource clinics in developing countries, however, no specific protocols or products are available for physicians in Denmark.

AB - This article describes penile fracture and testicular rupture and offers recommendations for management. Both conditions occur most commonly after blunt trauma. Diagnosis can be supported by imaging but is usually confirmed on surgical exploration, which in both cases should be carried out promptly. Penile fracture occurs most commonly related to coitus, and surgical correction decreases the risk of long-term erectile dysfunction, deformity and pain. Testicular rupture usually presents with persisting pain and haematoma after trauma, and surgery is recommended to minimize permanent organ damage.

AB - A 69-year-old female was admitted due to progressive loss of muscle strength following addition of fluconazole to long-term simvastatin treatment. Rhabdomyolysis was suspected and both drugs were discontinued. Forced diuresis was initiated together with a short course of prednisolone. After 21 weeks the patient had regained normal muscle strength and endurance. The favourable course and the absence of antibodies against 3-hydroxy-3-methylglutaryl-coenzyme A reductase suggest that the condition was due to interaction between the two drugs, which are both metabolized via the CYP3A4 pathway.

Early diagnosis can be challenging due to the non-specific symptoms such as back pain and fever. Diagnosis is verified by MRI. Microbial aetiology is pursued by blood cultures or surgical biopsy, however, some cases remain culture-negative. Long-term antibiotic treatment is standard of care. Some patients receive surgical treatment. One-year mortality is up to 20%. Recently, published data suggest that six weeks of antibiotics equals 12 weeks in culture-positive cases.

AB - Since 2005 multidisciplinary team conferences (MDT) has been a crucial pivot for the Danish national integrated cancer pathways. Despite the formal decision to implement MDT-conferences, many aspects of this complex organization have never been addressed. In 2014, The Danish Multidisciplinary Cancer Groups (DMCG) provided a workgroup with the task of drafting a Danish national guideline for keeping MDT-conferences. This article presents the process of the workgroup, the background for the final content of the guideline as well as minutes from different parts of the guideline. PMID- 27697128 TI - Nurse-initiated telephone follow-up on patients with chronic obstructive pulmonary disease improves patient empowerment, but cannot prevent readmissions. AB - INTRODUCTION: Readmissions reduce quality of life and increase mortality. Furthermore, disease severity and shortened length of stay make it difficult to support disease management during admission. The aim of this study was to explore whether telephone follow-up after discharge may reduce readmission rates, lower mortality and improve disease management in patients with chronic obstructive pulmonary disease (COPD). METHODS: This was a randomised controlled trial (n = 224) with nurse-initiated telephone intervention after discharge. On day 30, questionnaires about health status and perceptions of disease management were completed. Readmission and death were recorded on days 30 and 84. RESULTS: There was no significant difference in readmission rates, but significant differences in patients' assessment of own perception of managing dyspnoea, lung symptoms, ability to react to signs of exacerbation and communicate with health professionals. There was a trend towards a higher mortality in the control group, but it was not statistically significant. CONCLUSIONS: Nurse-initiated telephone follow-up does not reduce readmission rates, but does empower patients with COPD. FUNDING: The project was funded in part by the Capital Region of Denmark as part of the implementation of The National Plan for Elderly Medical Patients. TRIAL REGISTRATION: The Danish Data Protection Agency approved the project (j. no.NOH 2015-035) and approval was obtained from The Regional Ethics Committee (notification number 27518). PMID- 27697129 TI - Auditory profiling and hearing-aid satisfaction in hearing-aid candidates. AB - INTRODUCTION: Hearing-impaired (HI) listeners often complain about difficulties communicating in the presence of background noise, although audibility may be restored by a hearing-aid (HA). The audiogram typically forms the basis for HA fitting, i.e. people with similar audiograms are given the same prescription by default. This study aimed at identifying clinically relevant tests that may serve as an informative addition to the audiogram and which may relate more directly to HA satisfaction than the audiogram does. METHODS: A total of 29 HI and 26 normal hearing listeners performed tests of spectral and temporal resolution, binaural hearing, speech intelligibility in stationary and fluctuating noise and a working memory test. Six weeks after HA fitting, the HI listeners answered a questionnaire evaluating HA treatment. RESULTS: No other measures than masking release between fluctuating and stationary noise correlated significantly with audibility. The HI listeners who obtained the least advantage from fluctuations in background noise in terms of speech intelligibility experienced greater HA satisfaction. CONCLUSION: HI listeners have difficulties in different hearing domains that are not predictable from their audiogram. Measures of temporal resolution or speech perception in both stationary and fluctuating noise could be relevant measures to consider in an extended auditory profile. FUNDING: The study was supported by Grosserer L.F. Foghts Fond. TRIAL REGISTRATION: The protocol was approved by the Science Ethics Committee of the Capital Region of Denmark (reference H-3-2013-004). PMID- 27697130 TI - Lack of national consensus in preoperative airway assessment. AB - INTRODUCTION: Difficult airway management is associated with an increased risk of morbidity and mortality. Several preoperative risk factors associated with airway management difficulties have been proposed; however, no clear guideline for airway assessments exists. We therefore hypothesised that Danish airway assessment was lacking uniformity. We aimed to examine whether multivariable risk assessment tools and predictors for difficult intubation and mask ventilation were used systematically. METHODS: Heads of anaesthesia departments were sent a six-question survey at the beginning of 2012. We asked if systematic risk assessment tools, particularly the Simplified Airway Risk Index (SARI), and predictors for difficult intubation and mask ventilation were used. Additionally, we asked if any risk factors were pre-printed on the anaesthesia record. RESULTS: In all, 29 of 31 (94%) departments responded. The SARI was implemented in 8 of 29 (28%, 95% confidence interval (CI): 15-46%) departments with major regional differences. There was no significant association between using the SARI and a reduced number of unanticipated difficult intubation (p = 0.06). Mallampati classification (95.2%, 95% CI: 77.3-99.2%), history of airway management difficulties (85.7%, 95% CI: 65.4-95.0%), ability to prognath (81.0%, 95% CI: 60.0-92.3%) and neck mobility (81.0%, 95% CI: 60.0-92.3%) were the main predictors registered. CONCLUSION: We found considerable inter-departmental variance in the standards employed for airway assessment and no uniform pattern in the registration of risk factors for airway management difficulties. Better prediction of difficult intubation could not be detected in departments that used the SARI. FUNDING: none. TRIAL REGISTRATION: not relevant. PMID- 27697131 TI - Clinical management of acute diabetic Charcot foot in Denmark. AB - INTRODUCTION: Charcot foot is a severe complication to diabetes mellitus and treatment involves several different clinical specialities. Our objective was to describe the current awareness, knowledge and treatment practices of Charcot foot among doctors who handle diabetic foot disorders. METHODS: This study is based on a questionnaire survey sent out to healthcare professionals, primarily doctors, working with diabetic foot ulcers and Charcot feet in the public sector of the Danish healthcare system. RESULTS: The survey obtained a 52% response rate. A temperature difference of > 2 degrees C between the two feet was the most used method of diagnosing Charcot foot. Along with clinical inspection, temperature difference was also the measurement used for monitoring of healing. None of the suggested formalised classification systems were used to any extent. Most responders use detachable bandages for offloading (83%). All centres use some form of a multidisciplinary team, with the most common permanent members being orthopaedic surgeons (71%), wound specialist nurses (76%), podiatrists (65%), endocrinologists (47%) and diabetes specialist nurses (41%). CONCLUSION: We conducted a survey of the diagnosis and treatment practices of acute diabetic Charcot foot at diabetes foot clinics in Denmark. The responders seem to follow the international recommendations and guidelines on management of the acute diabetic Charcot foot, despite a lack of Danish guidelines. FUNDING: none.

AB - INTRODUCTION: Non-attended hospital appointments are receiving increasing attention in times when rapid access and efficient service delivery at public hospitals are on the agenda. The aim of this study was to investigate the extent of non-attendance in a Danish outpatient setting and its association with user level and provider-level characteristics. METHODS: The study was based on appointments scheduled from June 2013 to March 2015 at an orthopaedic and a radiologic outpatient clinic. Data on outcomes of cancellation on the part of the user or the provider, and non-attendance without giving notice were collected from administrative systems along with appointment characteristics. Logistic regression was used for statistical analysis. RESULTS: Of the 54,987 and 31,538 appointments scheduled at the two departments, 4,524 (8%) and 5,479 (17%) were cancelled and 2,905 (5%) and 1,249 (4%) were unattended without notice. The latter was significantly associated with male gender, younger age and longer time since referral. Other characteristics were identified as significant, but differed between departments. CONCLUSION: There seems to be a potential for a targeted effort aiming to reduce non-attendance and thereby to improve the efficiency of Danish outpatient services. Future studies should investigate the effect of initiatives such as nudging and fines targeting the appointments that have the highest non-attendance rates. FUNDING: Danish Regions, the Danish Ministry of Health and the Central Denmark Region funded the study. TRIAL REGISTRATION: not relevant. PMID- 27697133 TI - Cumulative incidence and registry validation of groin hernia repair in a 34-year nationwide cohort. AB - INTRODUCTION: The purpose of this study was to present a nationwide cumulative incidence and an age-specific incidence rate of groin hernia repair as well as to evaluate the validity of inguinal and femoral hernia operation codes in the Danish National Patient Registry (DNPR). METHODS: All persons born in Denmark from 1977 to 2010 were investigated for groin hernia operations registered in the DNPR with respect to date of admission, operation, discharge and specific operation codes. To validate the predictive values of registrations, we randomly extracted data on elective and emergency groin hernia operations from the DNPR from 2005 to 2010 and examined the medical records. RESULTS: The study population (n = 2,109,417) from 1977 to 2010 was followed from the primary groin hernia operation (n = 53,262) to 2010, yielding a total of 33.4 million person-years of follow-up. The probability of being operated for a groin hernia prior to the age of 34 years was 5.70% (95% confidence interval (CI): 5.62-5.78) for males and 1.26% (95% CI: 1.20-1.32) for females. The highest incidence rate was seen among males aged 0-1 years (10.19 (95% CI: 10.00-10.38)). The positive predictive value of patients registered with inguinal hernia operations in the DNPR who had been operated for an inguinal hernia was 100% (95% CI: 96-100%) and 91.3% (95% CI: 83 96%) for femoral hernia operations. CONCLUSIONS: The incidence rate of groin hernia operations peaked at the 0-1 year age group in males and at the 3-4-year age group in females. Furthermore, the validation of the DNPR showed very high positive predictive values for both inguinal hernia operations and femoral hernia operations. FUNDING: none. TRIAL REGISTRATION: not relevant. PMID- 27697134 TI - A characterisation of low-grade inflammation and metabolic complications in HIV infected patients. AB - HIV-associated lipodystrophy syndrome frequently presents as a relative lack of peripheral adipose tissue storage combined with an increase in visceral fat, associated with insulin resistance and dyslipidaemia. This thesis discusses explanations for the links between abnormalities in glucose metabolism, the steroid synthesis pathway, the growth hormone-insulin growth factor-1 axis, and chronic changes in adipose tissue distribution. Specifically, the mechanisms by which low-grade inflammation may affect the normal stimulatory effect of insulin on glucose and fat storage are reviewed. We propose that both chronic low-grade inflammation from HIV infection and treatment with HAART trigger cellular homeostatic stress responses with adverse effects on glucose metabolism. The physiological outcome is such that the total energy storage in the adipocytes is decreased, and the remaining adipocytes resist further energy storage. The excess circulating and dietary lipid metabolites, normally metabolised by adipose tissue, are deposited ectopically in the muscle, liver, or visceral adipose tissue, where they impair insulin action. This deposition of lipid metabolites leads to a vicious circle of insulin resistance and lipotoxicity leading to lipoatrophy or a mixed-type with increased visceral adipose tissue and a clinical phenotype of HIV-associated lipodystrophy syndrome with an elevated waist-to-hip ratio. This HIV-associated inflamm-ageing syndrome can provide a platform for further studies in HIV-infected patients and act as a model for biological accelerated ageing. PMID- 27697135 TI - Risk. Impact of having a first-degree relative with affective disorder: a 7-year follow-up study. AB - This study investigated a high-risk sample in order to elucidate risk factors for affective disorder. Healthy monozygotic (MZ) and dizygotic (DZ) twins with and without a co-twin with a history of affective disorder were identified through nationwide registers. Two risk groups were identified: the high-risk group comprised twins at risk of developing affective disorder (DZ or MZ twin; index co twin affected); the low risk group (control group) comprised twins at low risk of developing affective disorder (DZ or MZ twin; index co-twin not affected). At baseline 234 participants were divided into groups according to their risk for affective disorder; they were followed up at 6-month intervals with posted questionnaires assessing depression. After a mean follow-up period of 7 years, the participants were invited to participate in an individual interview. A total of 36 participants (31 high-risk twins and 5 low-risk twins) developed a psychiatric disorder during the 7-year follow-up period: 24 developed mood disorder (67%), 7 anxiety disorder (19%) and 5 (14%) substance abuse, schizophrenia or personality disorder. The results showed that familial risk, impaired stress tolerance and discrete cognitive dysfunction seem to be core predictors of affective illness. It is possible to identify a cluster of prodromal symptoms encompassing subclinical anxiety and depressive symptoms, higher neuroticism and cognitive problems. The cognitive problems may further be related to the cross-sectional finding that high-risk twins had lower hippocampal volumes. Further, 2 genetic polymorphisms: the 5-HTTLPR and the brain-derived neurotrophic factor (BDNF) Val66Met polymorphisms were not directly associated with familial risk for affective disorder and did not predict illness onset. Similarly, salivary cortisol levels and whole-blood BDNF levels did not predict subsequent illness. The more complex 2-way interactions between 5-HTTLPR and life events suggested that high-risk individuals and individuals carrying the short s allele are exposed to more stressors and that this seems to contribute to an overall enhanced risk and thus accelerate the onset of illness. Low-risk individuals seem to experience fewer life events and may exhibit resilience to their adverse psychological effects. Overall, having a 1st-degree relative with affective disorder matters. This thesis demonstrates that high-risk studies are informative, allowing observation and investigation of the pathological processes that occur prior to the onset of illness. There is a lack of prospective intervention studies assessing psychopathology in well-defined, high-risk samples and it is obvious that future research must transcend diagnostic boundaries in order to have an impact on prevention. Furthermore, there is a need to move beyond the notion of ''magic bullets'', instead developing an integrated paradigm encompassing clusters of biomarkers related to behavioural measures of developmental psychopathology. Finally, as most psychiatric treatment developed to date target end-state disorders, the identification of high-risk individuals and mapping of individual risk profiles should be a priority in order to facilitate early treatment and prevention. PMID- 27697136 TI - Childhood depressive disorders. AB - Major depressive disorder (MDD) is a frequent and painful mental disorder considered among the five leading causes of disability in Western countries by the World Health Organization. MDD occurs at all ages, but childhood onset MDD has a more severe course with longer depressive episodes, more suicidality, and more frequent hospitalization, than later onset MDD. Childhood seems to be a window of opportunity for prevention of mental disorders, and subsequently prevention of MDD onset in childhood is recommended. Feasible prevention targets either individuals who present early signs of a given disorder but have not reached diagnostic threshold (indicated prevention) or individuals who are at increased risk for a disorder due to risk factor exposure (selective prevention). Indicated prevention is rational also for depressive disorders, because subthreshold depression (SD) in adults is found to be a precursor to MDD. The purpose of this thesis was to provide information necessary for the prevention of MDD onset in childhood. First, we examined whether the literature supports that SD is a MDD precursor also in children (systematic review). Second, we explored the risk that gender might constitute for pre-pubertal and post-pubertal onset MDD (register study). Third, we estimated the prevalence of SD and MDD in a large scale pre-pubertal sample, and compared the clinical features of SD and MDD and potential risk factors (population-based study). The systematic review of the literature showed that SD in children and adolescents presents analogous comorbidity and symptom patterns (including self-harm symptoms). It also supports that SD is a precursor to MDD in children and adolescents causing poor outcomes like psychopathology, functional impairment and high use of health service. In the register study of Danish children and adolescents, we found a higher incidence of clinical MDD for girls after puberty compared to boys. Before puberty however, we demonstrated that boys had higher MDD incidence rates than girls. The population-based study including 3,421 8-10-year-old children from the Danish National Birth Cohort (DNBC) showed point prevalence estimates of 0.5% for MDD and 1.0% for SD. Children with SD by definition hold fewer depressive symptoms, but the ranking and frequency of these individual depressive symptoms was almost similar. Only irritability, anhedonia and worthlessness/guilt were more common in children with MDD. DNBC children with SD and MDD had comorbid anxiety or conduct/oppositional disorders just as frequently, and the degree of functional impairment was the same. When examining potential risk factors for SD and MDD, we found that poor general health, more than two stressful life events (SLE) within the past year, and a high level of maternal depressive symptoms were correlated to both SD and MDD. In addition we found epilepsy/convulsions, one SLE within the past year and parental divorce/separation to be correlated to MDD. In conclusion, the findings reported in this thesis underline that SD in childhood and adolescence is a significant condition calling for attention, due to the early onset, the risk for progression into MDD and the poor outcome. Indicated prevention aimed at MDD in childhood should target SD children who are characterised by fewer depressive symptoms but the same symptom pattern, the same level of impairment, and the same amount of comorbid anxiety and conduct/oppositional disorders, as presented by children with MDD. Selective preventive interventions could effectively target children who suffer from chronic physical illness and children whose mothers present depressive symptoms, also below clinical threshold. In addition, boys might have an increased risk for developing pre-pubertal MDD, but this has to be explored further in non-clinical samples. We recommend that more attention is paid to children and adolescents with subthreshold depressive symptoms who also pre-sent significant functional impairment. Emphasis must be put on the risk for SD transforming into MDD, especially in those exposed to the potential risk factors identified in this thesis. PMID- 27697137 TI - Cancer of the upper rectum. AB - Rectal cancer constitutes one-third of all colorectal cancers, and the incidence in Denmark increasing. In 2012, 1.400 cases were registered, and of these 38% were located in the upper rectum. There have been several key advances in the optimal management of rectal cancer during the past decades, primarily by standardisation and improvement of the surgical procedure. There is now general agreement that the optimal surgical treatment involves the concept of total mesorectal excision and that a resection with tumour-free margins is crucial. Controversy exists as to whether total mesorectal excision (TME) is necessary for upper rectal cancers or if a partial mesorectal excision (PME) with mesorectal transection 5 cm below the tumour is adequate. Furthermore, there is no agreement as to whether surgery alone is sufficient or whether neoadjuvant radio- and/or chemotherapy should be administered for tumours of the upper rectum. This thesis aims to discuss aspects of the treatment of rectal cancer with regard to the adequacy of mesorectal excision and oncological outcome with a particular focus on cancer of the upper rectum. In study I, the extent and completeness of mesorectal excision was estimated by postoperative magnetic resonance imaging of the pelvis in patients with primary surgery for rectal cancer. In the 136 patients with post-operative MRI, inadvertent residual mesorectal tissue was evident in 40%, especially following PME, suggesting suboptimal surgery performed. Additionally in patients who had PME, the distal margin was found to be less than 3 cm in more than 50% of patients, suggesting a discrepancy between guidelines and the actual surgery performed. In study II, we estimated the risk of local recurrence in the previously audited cohort of patients, with a particular focus on patients with upper rectal cancer treated by PME and without neo-adjuvant therapy as standard. Using Kaplan-Meier analysis, the total three year local recurrence rate was 7% with tumour stage and an involved circumferential margin as the most important predictors of local recurrence. The local recurrence rate after PME was significantly higher than for TME (14% vs. 3%; p=0.032), and were diagnosed earlier (p=0.001). In all cases with local recurrence following PME there was evidence of either inadvertent residual mesorectum and/or an insufficient distal resection margin. In study III, we investigated the length of the distal resection margin and degree of tissue shrinkage after surgical removal and fixation by using MRI of the fresh and fixed specimen. We found that the length of the specimen and the distal margin was reduced by 30% after surgical removal and fixation. If a 5-cm distal margin below the luminal level of the primary tumour on the fresh specimen is the objective for advanced cancer of the upper rectum treated with PME surgery, a margin of at least 3.5 cm of mesorectum on the fixed specimen should be attained for the pathologist to accurately establish distal radicality. PMID- 27697138 TI - Acceptance and Commitment Group Therapy (ACT-G) for health anxiety. AB - Health anxiety is prevalent (5-9%) in all healthcare settings and in the general population, may have an early onset, and a poor prognosis is seen in severe cases if untreated. Research shows that health anxiety is rarely diagnosed though it causes great suffering for the individual and constitutes a substantial socio economic burden. Studies have shown that individual cognitive behavioural therapy can relieve health anxiety, but these studies are affected by methodological problems, among others, struggling with patients declining participation, high dropout rates, and some patients not responding to the treatment. Moreover, the impact of health anxiety on sick leave is only scarcely examined. This thesis examines the effect of a new treatment approach, group-based Acceptance & Commitment Therapy (ACT-G) for patients with severe health anxiety in an uncontrolled pilot study and a randomised controlled study (RCT) on ACT-G compared with a 10-month waitlist control condition (paper I and II). Also, the thesis comprises a study on sick leave in patients with health anxiety compared with the general population during a 5-year period and the effect of ACT-G on sick leave. The findings from this study are described in paper III. Patients (age 20-60 years) consecutively referred from general practitioners from Jutland and Funen in the period of March 2010 - April 2012 (approx. 2.5 million citizens) to the Research Clinic for Functional Disorders and Psychosomatics, Aarhus University Hospital, were included. The pilot study included 34 patients, the RCT on ACT-G included 126 patients. In the RCT, patients were block randomised to either ACT-G and received treatment in 7 groups of each 9 patients in the period of December 2010 - October 2012, or to a 10-month waitlist control group. The primary outcome measure was the Whiteley-7 paper and pencil index for illness worrying. The last paper is based on data on sickness-related benefits from the DREAM social register of transfer benefits and also includes a matched general population register control cohort (n=12,600). In this thesis, we wish to answer the following questions: 1) Is ACT-G an acceptable, feasible and effective treatment approach for patients with severe health anxiety? 2) Can ACT-G improve severe illness worry compared with a waitlist control condition, and are the recently introduced diagnostic criteria for health anxiety acceptable for the patients? 3) Do patients with health anxiety show more sick leave than the general population during a 5-year period, and can ACT-G reduce sick leave measured by transfer benefits (weeks on sickness-related benefits) at 1-year follow-up? As ACT has not previously been examined as treatment approach for health anxiety, we initially conducted an uncontrolled pilot study to test the newly developed manualised program (ACT-G). The study included 34 patients with severe health anxiety and showed very low dropout and high treatment satisfaction. Significant improvements in self-reported illness worry were demonstrated post-treatment, and the results were sustained and further improved at 3- and 6-months follow-up compared to baseline. The subsequent RCT found high acceptance of the diagnosis of health anxiety. All patients (except 1) accepted the diagnosis as the right diagnosis to fit their ailment, and the majority of the patients found that the diagnosis helped them to better understand their symptoms. In an intention-to-treat analysis, ACT-G showed significant effect in the improvement of self-reported illness worry and other secondary measures compared with a waitlist control condition, both post-treatment and at 10-month follow-up (6 months post-treatment). The results were considered clinically significant as 2/3 of the patients in ACT-G at follow-up had demonstrated a pre defined treatment response, and 1/4 of the patients were considered to no longer have clinical case status. Furthermore, the number needed to treat was found to be 2.4. Patients with severe health anxiety showed significantly more weeks on sickness-related benefits than matched individuals from the general population during the 5 years prior to entering the RCT. This difference was stable until an estimated cut-point at 1 year before enrolment, where patients with health anxiety showed further increase in sickness-related-benefits. At one-year follow up (8 months post-treatment), we did not find a significant difference between ACT-G and the waitlist group in weeks on sickness-related benefits. Post-hoc analysis, however, revealed a significant decrease in weeks on sickness-related benefits for ACT-G during the 2 years after randomisation. In conclusion, the thesis suggests that ACT-G is both an acceptable and effective treatment approach for patients with severe health anxiety. Hopefully, these findings can contribute to the future research and identification of which treatment approaches are the most effective and for which patients and contribute to tailored, early interventions. This may possibly prevent development of otherwise chronic symptoms, increase the quality of life for the patients, and potentially reduce socio-economic costs. PMID- 27697139 TI - The analgesic effects of exogenous melatonin in humans. AB - The hormone, melatonin is produced with circadian rhythm by the pineal gland in humans. The melatonin rhythm provides an endogenous synchronizer, modulating e.g. blood pressure, body temperature, cortisol rhythm, sleep-awake-cycle, immune function and anti-oxidative defence. Interestingly, a number of experimental animal studies demonstrate significant dose-dependent anti-nociceptive effects of exogenous melatonin. Similarly, recent experimental- and clinical studies in humans indicate significant analgesic effects. In study I, we systematically reviewed all randomized studies investigating clinical effects of perioperative melatonin. Meta-analyses demonstrated significant analgesic and anxiolytic effects of melatonin in surgical patients, equating reductions of 20 mm and 19 mm, respectively on a VAS, compared with placebo. Profound heterogeneity between the included studies was, however, present. In study II, we aimed to investigate the analgesic, anti-hyperalgesic and anti-inflammatory effects of exogenous melatonin in a validated human inflammatory pain model, the human burn model. The study was performed as a randomized, double blind placebo-controlled crossover study. Primary outcomes were pain during the burn injury and areas of secondary hyperalgesia. No significant effects of exogenous melatonin were observed with respect to primary or secondary outcomes, compared to placebo. Study III and IV estimated the pharmacokinetic variables of exogenous melatonin. Oral melatonin demonstrated a tmax value of 41 minutes. Bioavailability of oral melatonin was only 3%. Elimination t1/2 were approximately 45 minutes following both oral and intravenous administration, respectively. High-dose intravenous melatonin was not associated with increased sedation, in terms of simple reaction times, compared to placebo. Similarly, no other adverse effects were reported. In Study V, we aimed to re-analyse data obtained from a randomized analgesic drug trial by a selection of standard statistical test. Furthermore, we presented an integrated assessment method of longitudinally measured pain intensity and opioid consumption. Our analyses documented that the employed statistical method impacted the statistical significance of post-operative analgesic outcomes. Furthermore, the novel integrated assessment method combines two interdependent outcomes, lowers the risk of type 2 errors, increases the statistical power, and provides a more accurate description of post-operative analgesic efficacy. Exogenous melatonin may offer an effective and safe analgesic drug. At this moment, however, the results of human studies have been contradictory. High quality randomized experimental- and clinical studies are still needed to establish a "genuine" analgesic effect of the drug in humans. Other perioperative effects of exogenous melatonin should also be investigated, before melatonin can be introduced for clinical routine use in surgical patients. Despite promising experimental and clinical findings, several unanswered questions also relate to optimal dosage, timing of administration and administration route of exogenous melatonin. PMID- 27697140 TI - Individual fertility assessment and counselling in women of reproductive age. AB - The overall aim of this thesis was to validate the new concept of the Fertility Assessment and Counselling (FAC) Clinic at Rigshospitalet. The intention was to: explore the prognostic value of fertility risk factors by a risk score and provide an estimate of female fecundity, to quantify the impact of oral contraception (OC) on ovarian reserve parameters defined as Anti Mullerian Hormone (AMH), Antral Follicle Count (AFC) and ovarian volume, and to gain knowledge of attitudes and considerations toward family formation in women of advanced age. The thesis is based on the following four manuscripts: Manuscript I describes the predictive value of individual fertility assessment and counselling in terms of subsequent time to pregnancy within two years after the initial consultation at the FAC Clinic. The follow up study comprised 519 women, of which 352 had tried to conceive. At the time of follow-up, 259/352 had achieved a pregnancy, 74/352 were still trying and 19/352 had given up. The remaining 167 women had no attempts to conceive. The risk assessment provided a score based on the appearance of fertility risk factors: green (low), yellow (low), orange (medium) and red (high). Two-thirds of the women with only low risk scores conceived spontaneously within 12 months (65%), while this figure was only 32% for women with at least one high risk score (n=82). Accordingly, presence of at least one high risk score reduced the odds of achieving a pregnancy within 12 months by 73% (OR 0.27, 95%CI 0.13-0.57). The FAC Clinic concept seems as a usable tool for fertility experts to guide women on how to fulfil their reproductive life-plan, but longer follow-up studies are needed. Manuscript II describes the impact of OC on ovarian reserve parameters in 887 women at the FAC Clinic. Of the 887 women, 244 (27.5%) used OC. The 244 users of OC were significantly younger than non-users with a mean age of 31.5 (SD 4.3) vs. 34.1 (SD 4.3) years (p < 0.001). Overall, there was no difference between the two groups in relation to bodyweight, BMI, smoking habits, gestational age at birth, prenatal exposure to maternal smoking or maternal age at menopause. In linear regression analyses adjusted for age, ovarian volume was 50% lower, AMH was 19% lower, and AFC was 18% lower in OC-users compared to non-users. Among the OC users there was a significant decrease in antral follicles sized 5-7 and 8-10 mm and an increase in the number of small follicles sized 2-4 mm. Physicians have to be aware of the impact of OC use on ovarian reserve parameters and possible concealment of premature ovarian insufficiency, when assessing the fertility status and estimating the reproductive lifespan in OC users. Manuscript III describes the family intentions and personal considerations on postponing childbearing in 340 childless women of advanced age. The study comprised 140 cohabiting and 200 single women aged 35-43 seeking fertility assessment and counselling at the FAC Clinic. The majority (82%) was well-educated and in employment. Despite their mean age of 37.4 years, the main reasons for attending the FAC Clinic were to gain knowledge on the possibility of postponing pregnancy (63%) and due to a concern about their fecundity (52%). Both the cohabiting and single women expressed a wish for two or more children (60%). The most important benefits were "personal development" (89%) and "to give and receive love" (86%). The main concerns about childbearing were "less time to myself" (82%) and "less time to job and career" (76%). The single women were more positive regarding the use of donor sperm (70%) compared to the cohabiting women (25%). Our results indicated a general overestimation of the women's own reproductive capacity and an underestimation of their risk of future infertility and childlessness with continuous postponement of pregnancies. Manuscript IV describes attitudes toward family formation in ten single and ten cohabiting childless women of advanced age. The women were interviewed one week before their consultation at the FAC Clinic about their family formation intentions, considerations and concerns. The interviews were analysed and condensed into four categories: ''The biological clock'', ''The difficult choice'', ''The dream of the nuclear family'', and ''Mother without a father''. The categories were condensed into two subthemes; 'Fear' and 'Expectations' and gathered into one main theme 'The conflict of choosing', which reflected the women's attitudes toward family formation prior to individual fertility counselling. The women attended the FAC Clinic due to a concern about their fecundity and a fear for infertility. Overall, the women expressed a dream of the nuclear family and finding "Mr. Right" and many with the wish of buying more time. Both groups would consider solo motherhood due to their advanced age, although it was considered to be Plan B, as it was not "natural". PMID- 27697141 TI - Follicular T helper cells and IL-21 in rheumatic diseases. AB - Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are lifelong diseases with increased mortality and chronic pains. They are both characterized by immunological imbalances causing the immune system attack and destroy the bodies own tissues (called autoimmune disease). The best treatment, we are currently able to offer these patients, cause significant side-effects and can not prevent significant loss of quality of life. At the heart of the disease mechanisms in RA and SLE are subsets of immune cells called T and B cells. These cell types produce proteins (called antibodies), which under normal circumstances protect the body against disease. In RA and SLE these cells produce antibodies that are directed at the bodies own tissues (called autoantibodies), causing inflammation and tissue damage. The cause of this loss of tolerance is still unknown. Interleukin 21 (IL-21) is thought to exert key functions in controlling and directing the T and B cell responses leading to formation of antibodies and autoantibodies alike. IL-21 is a signaling molecule secreted by a subpopulation of T cells called follicular T helper (Tfh) cells. IFNalpha is another signaling molecule of key importance in autoimmune disease. Stratification of SLE patients by their responsiveness to IFNalpha has proven a crucial tool in stratifying patients in terms of disease development and treatment response. The aim of this PhD study is to investigate the role of IL-21 and IFNalpha, and their effects on Tfh cells and B cells and the formation of autoantibodies in RA and SLE. The first part of this study addresses whether plasma levels of IL-21 influence disease activity in rheumatic disease. We further investigate the distribution of IL-21-producing Tfh cells in these patients. We find that IL-21 plasma levels correlate to disease activity and radiological progression in RA, and that the IL 21-producing Tfh cell are increased in the blood and synovial fluid of these patients. These findings support the idea that IL-21 and Tfh cells are linked to the development and perpetuation of these diseases. In the second part of this we investigate how small RNA molecules, called microRNAs, can regulate immunological processes. We find that microRNA-155 can regulate IL-21's capacity to signal, while microRNA-21 is important for survival of T cells. The third, and last part of this, concerns IFNalpha signaling and its impact on the development of SLE and the formation of autoantibodies. We find that IFNalpha signaling is altered in a murine model of SLE, and that inhibition of this signaling pathway leads to severe kidney disease. The latter is of key importance as inhibition of IFNalpha is currently in early trial as a new treatment form for SLE patients. In SLE patients, we find that IFNalpha responsiveness, as measured by a so-called IFN signature, is crucial in terms of development of the disease as well as serious complications such as kidney disease and involvement of the central nervous system. Interferon alpha does this by affecting intracellular signaling responses and the formation of autoantibodies. The data presented in this thesis supports that IL-21 and Tfh cells have a key role in the disease processes characterizing RA and SLE. We further describe a novel mechanism for microRNA-155 and microRNA 21 in regulating immunological processes in these diseases. Finally we show, that IFNalpha has important functions in the formation of autoantibodies in SLE. In conclusion, this thesis adds new and important knowledge on the interplay between Tfh cells and B cells and their formation of autoantibodies in rheumatic disease. This knowledge will guide and further the development of new treatment strategies to better patient outcome. PMID- 27697142 TI - Resistance in human pathogenic yeasts and filamentous fungi: prevalence, underlying molecular mechanisms and link to the use of antifungals in humans and the environment. AB - Antifungal drug resistance is a multifaceted clinical challenge, and when present, a primary cause of treatment failure in patients with severe fungal infections. Changing epidemiology, increasing resistance rates and a narrow antifungal armamentarium may further underline the required attention on resistance particularly within the most prevalent invasive fungal infections caused by Candida yeasts and Aspergillus moulds. In Denmark, the resistance epidemiology remains to be fully elucidated. This thesis sought to address this demand as well as provide insight into the landscape of underlying molecular resistance mechanisms. Paper I and II both contributed to the understanding of FKS (beta-glucan synthase) mediated echinocandin resistance in Candida species. Paper I covered a unique stepwise acquisition of a homozygous mutation in FKS1 of Candida tropicalis leading to an amino acid change corresponding to a well-known S645P in Candida albicans. Paper II presented a failure case due to Candida krusei displaying high-level echinocandin resistance likely attributable to an acquired D662Y amino acid substitution in FKS1. Intrinsic differences in FKS1 among Candida species may explain why the level of resistance both depends on the mutation as well as the species and cannot be easily translated to the level of clinical resistance. Intrinsic fluconazole resistance in C. krusei further substantiated the clinical implications of acquired echinocandin resistance. Paper III presented a rare multidrug resistance case in a series of isogenic C. albicans isolates, almost covering the entire spectrum of known resistance mechanisms in Candida and involved the proposal of novel resistance mutations. An A61E change in ERG11 was potentially involved in reduced susceptibility to long structured azoles. Increased expression levels of azole efflux pumps were probably accredited to novel gain-of-function variants in the transcription factor TAC1 (R688Q and R673L). Echinocandin resistance was induced by the well known S645P variant of FKS1 and polyene resistance was likely inflicted by a frameshift mutation in ERG2 leading to loss of function of the encoded protein and subsequent ergosterol depletion. The number of acquired resistance cases is increasing in our settings and Paper IV sought to illuminate whether antifungal resistance is overlooked in the current fungaemia programme. This involved the acquisition of post-treatment oral isolates from 193 candidaemia patients among which 114 received azoles (primarily fluconazole) and 85 received an echinocandin (and some both). Azole-exposed patients carried a significantly higher proportion of species less susceptible to fluconazole (primarily Candida glabrata) among colonising Candida compared to baseline blood isolates (p<0.001). A similar trend was seen for echinocandin-treated patients although not statistically significant. Interestingly, there was a high frequency of acquired resistance, 29.4% to fluconazole and 21.6% to echinocandins, among colonising C. glabrata isolates post treatment. These figures were both significantly higher compared to baseline blood isolates as well as oral isolates from patients with no or minimal exposure to either drug class. In contrast, acquired resistance among C. albicans oral isolates was rare (<5). Thus, the oral cavity may be an unrecognized reservoir of resistant Candida species, especially C. glabrata following azole or echinocandin treatment. This underlines the care of which therapeutic stewardship must be taken both for antifungal naive patients, to avoid resistance development, as well as for patients previously exposed to antifungals. Paper V presented four fatal cases of invasive aspergillosis involving azole resistant Aspergillus fumigatus harbouring resistance mechanisms (TR34/L98H and TR46/Y121F/T289A), which are thought to derive from environmental fungicide use. The clinical concern is evident because the route of infection is through inhalation of potentially azole resistant spores. Still, recent environmental surveys were unable to detect azole resistant A. fumigatus in numerous soil samples but seasonal variations could be one explanation for this paradox. Paper VI was a retrospective laboratory-based study and aimed to elucidate the prevalence of azole resistance in A. fumigatus isolates from 2010-2014 in Denmark. This study also sought to uncover the underlying resistance mechanisms, primarily attributable to CYP51A mutations, and finally to assess the accumulated genotyping data. Among 1,162 A. fumigatus isolates, 94.5% were screened for azole resistance and a significant increasing trend was observed for the number of azole-resistant isolates to approximately 6% in 2014 (p<0.001) and 4% in corresponding patients (p<0.05). The underlying resistance mutations were diverse but still dominated by the TR34/L98H resistance mechanism responsible for >50% of all our azole-resistant isolates. The genotyping data of resistant and a selection of susceptible A. fumigatus showed high identity to foreign isolates (>15%). This could argue for the hypothesis on clonal expansion, which has previously been suggested for TR34/L98H clones in the Netherlands and India, but could also indicate an insufficient discriminatory power of such analysis. Still, a proposed A. fumigatus outbreak in a haematology ward was unresolved since no genetically identical isolates were recovered from patients and air samples, illustrating the ubiquitous nature of this organism. Overall, the main concerns are a changing Candida epidemiology towards species less susceptible to fluconazole combined with the rapid acquisition of echinocandin resistance, especially among C. glabrata isolates. For A. fumigatus, the concern is the emergence of azole resistant strains in the environment, displaying cross resistance to clinical azoles, and thus posing unforeseen clinical challenges in the management of invasive aspergillosis. Collectively, these findings call for an increased awareness especially at clinical microbiology laboratories, which ideally would lead to susceptibility testing of all clinically relevant isolates by reference or validated methods. Moreover, novel diagnostic approaches for non culturable pathogens are warranted and especially DNA-based detection by PCR may serve as a solid complimentary tool for improved diagnostics of invasive fungal infections. PMID- 27697143 TI - Community-Acquired Pneumonia-an Underestimated Challenge. PMID- 27697145 TI - Longitudinal Data Are Needed. PMID- 27697144 TI - Pneumonia in the Noninstitutionalized Older Population. AB - BACKGROUND: Pneumonia is a common and potentially serious disease, with an incidence of ca. 300 per 100 000 persons per year. Until now, there have been only a few population-based studies of risk factors for pneumonia. METHODS: From 2000 to 2002, nearly 10 000 persons aged 50 to 75 were recruited into the prospective ESTHER cohort study while visiting their family physician for a check up. The mean duration of follow-up was 10.6 years. Data on newly diagnosed pneumonia were acquired from the participants and their physicians by means of standardized questionnaires. Potential associations with various predictors were studied in survival-time regression models. RESULTS: 435 participants had pneumonia at least once during follow-up. The cumulative 10-year-incidence was 4.5% (95% confidence interval [4.0; 4.9]). Multiple regression revealed that age (relative risk [RR]: 1.43 [1.22; 1.67] per 10 years), current cigarette smoking (RR: 1.56 [1.19; 2.05], compared with never having smoked), and known congestive heart failure (RR: 1.65 [1.24; 2.20]) were independently associated with an elevated risk of pneumonia. The risk was insignificantly elevated in persons with diabetes mellitus (RR: 1.29 [0.98; 1.68]). Alcohol consumption, obesity, stroke, and cancer were not associated with an elevated risk of pneumonia in age- and sex adjusted analyses. CONCLUSION: Pneumonia plays an important role in the medical care of non-institutionalized older people. With the aid of the predictors identified in this study, primary care physicians can identify patients at risk, smokers can gain additional motivation to quit, treatment compliance can be increased, and patients may become more willing to be vaccinated as recommended in the current guidelines. PMID- 27697146 TI - In Reply. PMID- 27697147 TI - The Pharmacological Therapy of Chronic Neuropathic Pain. AB - BACKGROUND: Chronic neuropathic pain, including painful peripheral polyneuropathy and post-herpetic neuralgia, affects 6.9-10% of the general population. METHODS: In this article, we present current treatment recommendations on the basis of a selective review of the literature. RESULTS: Neuropathic pain does not respond consistently to classic non-opioid analgesic drugs and is better treated with co analgesic, antidepressant, and anticonvulsant drugs and topical agents. Under certain conditions, however, neuropathic pain can be treated with opioids, even chronically. It was concluded in a large-scale m eta- analysis that tricyclic antidepressants, selective serotonin- norepinephrine reuptake inhibitors, and calcium-channel anticonvulsants are the drugs of first choice, with a number needed to treat (NNT) of 3.5-7.7 for a 50% reduction of pain. An analysis of all studies yielded an estimated publication bias of 10%. Treatment planning must include adequate consideration of the patient's age and comorbidities, concomitant medication, and potential side effects. CONCLUSION: Drugs are now chosen to treat neuropathic pain independently of the cause and symptoms of the pain. Topical agents are used only to treat peripheral neuropathy. The utility of a treatment approach based on the patient's symptoms and pathological mechanisms was recently demonstrated for the first time in a randomized trial. The goal of current research is to facilitate treatment planning on the basis of the clinical phenotype. PMID- 27697149 TI - Limitations to photosynthesis by proton motive force-induced photosystem II photodamage. AB - The thylakoid proton motive force (pmf) generated during photosynthesis is the essential driving force for ATP production; it is also a central regulator of light capture and electron transfer. We investigated the effects of elevated pmf on photosynthesis in a library of Arabidopsis thaliana mutants with altered rates of thylakoid lumen proton efflux, leading to a range of steady-state pmf extents. We observed the expected pmf-dependent alterations in photosynthetic regulation, but also strong effects on the rate of photosystem II (PSII) photodamage. Detailed analyses indicate this effect is related to an elevated electric field (Deltapsi) component of the pmf, rather than lumen acidification, which in vivo increased PSII charge recombination rates, producing singlet oxygen and subsequent photodamage. The effects are seen even in wild type plants, especially under fluctuating illumination, suggesting that Deltapsi-induced photodamage represents a previously unrecognized limiting factor for plant productivity under dynamic environmental conditions seen in the field. PMID- 27697148 TI - The Arabidopsis transcription factor ABIG1 relays ABA signaled growth inhibition and drought induced senescence. AB - Drought inhibits plant growth and can also induce premature senescence. Here we identify a transcription factor, ABA INSENSITIVE GROWTH 1 (ABIG1) required for abscisic acid (ABA) mediated growth inhibition, but not for stomatal closure. ABIG1 mRNA levels are increased both in response to drought and in response to ABA treatment. When treated with ABA, abig1 mutants remain greener and produce more leaves than comparable wild-type plants. When challenged with drought, abig1 mutants have fewer yellow, senesced leaves than wild-type. Induction of ABIG1 transcription mimics ABA treatment and regulates a set of genes implicated in stress responses. We propose a model in which drought acts through ABA to increase ABIG1 transcription which in turn restricts new shoot growth and promotes leaf senescence. The results have implications for plant breeding: the existence of a mutant that is both ABA resistant and drought resistant points to new strategies for isolating drought resistant genetic varieties. PMID- 27697150 TI - A near atomic structure of the active human apoptosome. AB - In response to cell death signals, an active apoptosome is assembled from Apaf-1 and procaspase-9 (pc-9). Here we report a near atomic structure of the active human apoptosome determined by cryo-electron microscopy. The resulting model gives insights into cytochrome c binding, nucleotide exchange and conformational changes that drive assembly. During activation an acentric disk is formed on the central hub of the apoptosome. This disk contains four Apaf-1/pc-9 CARD pairs arranged in a shallow spiral with the fourth pc-9 CARD at lower occupancy. On average, Apaf-1 CARDs recruit 3 to 5 pc-9 molecules to the apoptosome and one catalytic domain may be parked on the hub, when an odd number of zymogens are bound. This suggests a stoichiometry of one or at most, two pc-9 dimers per active apoptosome. Thus, our structure provides a molecular framework to understand the role of the apoptosome in programmed cell death and disease. PMID- 27697151 TI - Inhibiting poly(ADP-ribosylation) improves axon regeneration. AB - The ability of a neuron to regenerate its axon after injury depends in part on its intrinsic regenerative potential. Here, we identify novel intrinsic regulators of axon regeneration: poly(ADP-ribose) glycohodrolases (PARGs) and poly(ADP-ribose) polymerases (PARPs). PARGs, which remove poly(ADP-ribose) from proteins, act in injured C. elegans GABA motor neurons to enhance axon regeneration. PARG expression is regulated by DLK signaling, and PARGs mediate DLK function in enhancing axon regeneration. Conversely, PARPs, which add poly(ADP-ribose) to proteins, inhibit axon regeneration of both C. elegans GABA neurons and mammalian cortical neurons. Furthermore, chemical PARP inhibitors improve axon regeneration when administered after injury. Our results indicate that regulation of poly(ADP-ribose) levels is a critical function of the DLK regeneration pathway, that poly-(ADP ribosylation) inhibits axon regeneration across species, and that chemical inhibition of PARPs can elicit axon regeneration.

PMID- 27697152 TI - NusG inhibits RNA polymerase backtracking by stabilizing the minimal transcription bubble. AB - Universally conserved factors from NusG family bind at the upstream fork junction of transcription elongation complexes and modulate RNA synthesis in response to translation, processing, and folding of the nascent RNA. Escherichia coli NusG enhances transcription elongation in vitro by a poorly understood mechanism. Here we report that E. coli NusG slows Gre factor-stimulated cleavage of the nascent RNA, but does not measurably change the rates of single nucleotide addition and translocation by a non-paused RNA polymerase. We demonstrate that NusG slows RNA cleavage by inhibiting backtracking. This activity is abolished by mismatches in the upstream DNA and is independent of the gate and rudder loops, but is partially dependent on the lid loop. Our comprehensive mapping of the upstream fork junction by base analogue fluorescence and nucleic acids crosslinking suggests that NusG inhibits backtracking by stabilizing the minimal transcription bubble.

AB - Pulsed light (PL) inactivation of two human norovirus (HuNoV) surrogates, murine norovirus (MNV-1) and Tulane virus (TV), and two bacterial pathogens, Escherichia coli O157:H7 and Salmonella, were evaluated. The viruses and bacteria were suspended in phosphate buffered saline (PBS) to final populations of ~6 log PFU/mL and ~6 log CFU/mL, respectively. Both viral and bacterial suspensions were then irradiated by PL for different durations and the reductions of each microorganisms were determined. MNV-1 and TV were significantly (P < 0.05) more resistant to PL treatment than Salmonella and E. coli O157:H7 in PBS suspension. MNV-1, Salmonella and E. coli O157:H7 were also inoculated on strawberries and blueberries and the PL inactivation of each microorganism was determined. Lower inactivation of each microorganism was achieved on berry surfaces than in PBS suspension. This study shows that PL can induce rapid inactivation of MNV-1, TV, Salmonella and E. coli O157:H7 in clear suspension with viruses more resistant to PL treatment than bacteria. The efficacy of PL treatment is substantially influenced by food surface structure. PMID- 27697160 TI - Comparison of three extraction methods to detect noroviruses in dairy products. AB - Noroviruses (NoV) are currently the most common cause of viral foodborne diseases and RT-qPCR is widely used for their detection in food because of its sensitivity, specificity and rapidity. The ISO/TS (15216-1, 15216-2) procedures for detecting NoV and HAV in high-risk food categories such as shellfish, bottled water and vegetables were published in 2013. Milk products are less implicated in foodborne viral outbreaks but they can be contaminated with fruit added to these products or by the food handler. Thus, the development of sensitive and reliable techniques for the detection of NoV in dairy products is needed to ensure the safety of these products. The aim of this study was to develop a RT-qPCR based method for the detection of NoV in milk products. Three methods were tested to recover NoV from artificially contaminated milk and cottage cheese. The selected method was based on the use of proteinase K and the recovery efficiencies ranged from 54.87% to 98.87% for NoV GI, 61.16%-96.50% for NoV GII. Murine norovirus and mengovirus were used as process controls and their recovery efficiencies were respectively 60.59% and 79.23%. The described method could be applied for detecting NoV in milk products for routine diagnosis needs. PMID- 27697159 TI - Application of phage therapy during bivalve depuration improves Escherichia coli decontamination. AB - The present study investigated the potential application of the bacteriophage (or phage) phT4A, ECA2 and the phage cocktail phT4A/ECA2 to decrease the concentration of Escherichia coli during the depuration of natural and artificially contaminated cockles. Depuration in static seawater at multiplicity of infection (MOI) of 1 with single phage suspensions of phT4A and ECA2 was the best condition, as it decreased by ~2.0 log CFU/g the concentration of E. coli in artificially contaminated cockles after a 4 h of treatment. When naturally contaminated cockles were treated in static seawater with single phage suspensions and the phage cocktail, similar decreases in the concentration of E. coli (~0.7 log CFU/g) were achieved. However, when employing the phage cocktail, a longer treatment time was required to obtain comparable results to those achieved when using single phage suspensions. When naturally contaminated cockles were depurated with phage phT4A in a recirculated seawater system (mimicking industrial depuration conditions), a 0.6 log CFU/g reduction of E. coli was achieved after a 2 h of treatment. When the depuration process was performed without phage addition, a 4 h treatment was necessary to obtain a similar decrease. By combining phage therapy and depuration procedures, a reduction in bivalves depuration period can be achieved for, thus decreasing the cost associated with this procedure and even enhance the quality and safety of depurated bivalves destined for human consumption. PMID- 27697161 TI - The influence of dissolved oxygen level and medium on biofilm formation by Campylobacter jejuni. AB - Campylobacter jejuni survival in aerobic environments has been suggested to be mediated by biofilm formation. Biofilm formation by eight C. jejuni strains under both aerobic and microaerobic conditions in different broths (Mueller-Hinton (MH), Bolton and Brucella) was quantified. The dissolved oxygen (DO) content of the broths under both incubation atmospheres was determined. Biofilm formation for all strains was highest in MH broth under both incubation atmospheres. Four strains had lower biofilm formation in MH under aerobic as compared to microaerobic incubation, while biofilm formation by the other four strains did not differ under the 2 atm. Two strains had higher biofilm formation under aerobic as compared to microaerobic atmospheres in Bolton broth. Biofilm formation by all other strains in Bolton, and all strains in Brucella broth, did not differ under the 2 atm. Under aerobic incubation DO levels in MH > Brucella > Bolton broth. Under microaerobic conditions levels in MH = Brucella > Bolton broth. Levels of DO in MH and Brucella broth were lower under microaerobic conditions but those of Bolton did not differ under the 2 atm. Experimental conditions and especially the DO of broth media confound previous conclusions drawn about aerobic biofilm formation by C. jejuni. PMID- 27697162 TI - Influence of PDO Ragusano cheese biofilm microbiota on flavour compounds formation. AB - The objectives of the present study were to characterize the biofilm microbiota of 11 different farms (from A to K), producing PDO Ragusano cheese, and to investigate on its ability to generate volatile organic compounds (VOCs) in milk samples inoculated with biofilm and incubated under Ragusano cheese making conditions. The biofilms were subjected to plate counting and PCR/T/DGGE analysis and the VOCs generated in incubated milk samples were evaluated through SmartNose, GC/O, and GC/MS. Streptococcus thermophilus was the dominant species both in biofilms and in incubated milks. Lactobacillus, Lactococcus, Enterococcus and Leuconostoc were also identified. Low levels of Pseudomonas spp. and yeasts counts were detected, whereas coliforms, Listeria monocytogenes and Salmonella spp., were never found. SmartNose and GC/O analyses were able to differentiate incubated milk samples on the basis of the odour compounds, highlighting that samples E and F overlapped and sample C was clearly separated from the others. These results complied with those acquired by GC/MS analysis, that detected in total 20 VOCs. Principal component analysis showed positive correlations (r > 0.6; P < 0.05) between some lactic acid bacteria (LAB) and VOCs: such as Enterococcus hirae with alcohols, Lactococcus lactis, Lactobacillus plantarum, Lactobacillus casei and Lactobacillus delbrueckii with aldehydes, and Lactobacillus fermentum, Lactobacillus helveticus and Lactobacillus hilgardii with ketones. This work demonstrates that biofilm represents an excellent source of LAB biodiversity, which contribute to generate VOCs during the production of PDO Ragusano cheese. PMID- 27697163 TI - Cell wall polysaccharides released during the alcoholic fermentation by Schizosaccharomyces pombe and S. japonicus: quantification and characterization. AB - The present work demonstrates that yeasts belonging to the Schizosaccharomyces genus release a high quantity of polysaccharides of cell wall origin starting from the onset of the alcoholic fermentation. By the end of the alcoholic fermentation, all of the Schizosaccharomyces yeast strains released a quantity of polysaccharides approximately 3-7 times higher than that released by a commercial Saccharomyces cerevisiae yeast strain under the same fermentative conditions of synthetic juice. A higher content of polysaccharide was found in media fermented by Schizosaccharomyces japonicus with respect to that of Schizosaccharomyces pombe. Some of the strains evaluated were also able to produce high levels of pyruvic acid, which has been shown to be an important compound for color stability of wine. The presence of strains with different malic acid consumption patterns along with high polysaccharide release would enable production of naturally modified wines with enhanced mouth feel and reduced acidity. The chemical analysis of the released polysaccharides demonstrated divergence between the two yeast species S. pombe and S. japonicus. A different mannose/galactose ratio and a different percentage of proteins was observed on the polysaccharides released by S. pombe as compared to S. japonicus. Analysis of the proteins released in the media revealed the presence of a glycoprotein with a molecular size around 32-33 kDa only for the species S. japonicus. Mass spectrometry analysis of carbohydrate moieties showed similar proportions among the N-glycan chains released in the media by both yeast species but differences between the two species were also observed. These observations suggest a possible role of rapid MALDI-TOF screening of N-glycans compositional fingerprint as a taxonomic tool for this genus. Polysaccharides release in the media, in particular galactomannoproteins in significant amounts, could make these yeasts particularly interesting also for the industrial production of exogenous polysaccharide preparations. PMID- 27697164 TI - Biodiversity of mycobiota throughout the Brazil nut supply chain: From rainforest to consumer. AB - A total of 172 Brazil nut samples (114 in shell and 58 shelled) from the Amazon rainforest region and Sao Paulo state, Brazil was collected at different stages of the Brazil nut production chain: rainforest, street markets, processing plants and supermarkets. The mycobiota of the Brazil nut samples were evaluated and also compared in relation to water activity. A huge diversity of Aspergillus and Penicillium species were found, besides Eurotium spp., Zygomycetes and dematiaceous fungi. A polyphasic approach using morphological and physiological characteristics, as well as molecular and extrolite profiles, were studied to distinguish species among the more important toxigenic ones in Aspergillus section Flavi and A. section Nigri. Several metabolites and toxins were found in these two sections. Ochratoxin A (OTA) was found in 3% of A. niger and 100% of A. carbonarius. Production of aflatoxins B and G were found in all isolates of A. arachidicola, A. bombycis, A. nomius, A. pseudocaelatus and A. pseudonomius, while aflatoxin B was found in 38% of A. flavus and all isolates of A. pseudotamarii. Cyclopiazonic acid (CPA) was found in A. bertholletius (94%), A. tamarii (100%), A. caelatus (54%) and A. flavus (41%). Tenuazonic acid, a toxin commonly found in Alternaria species was produced by A. bertholletius (47%), A. caelatus (77%), A. nomius (55%), A. pseudonomius (75%), A. arachidicola (50%) and A. bombycis (100%). This work shows the changes of Brazil nut mycobiota and the potential of mycotoxin production from rainforest to consumer, considering the different environments which exist until the nuts are consumed. PMID- 27697165 TI - Evaluation of different conditions to enhance the performances of Lactobacillus pentosus OM13 during industrial production of Spanish-style table olives. AB - The main objective was to set up a methodology to improve the high volume production of green table olives, cv. Nocellara del Belice. Lactobacillus pentosus OM13 was applied during three different industrial processes of table olives as follows: trial one (IOP1) was subjected to an addition of lactic acid until a brine level of pH 7.0 was reached; trial two (IOP2) subjected to same addition of lactic acid as in trial one plus nutrient adjuvant and trial three (IOP3) subjected to same addition as trial two, but with the strain L. pentosus OM13 acclimatized in brine for 12 h before inoculation. These trials were compared against two untreated controls (spontaneously fermented and addition of L. pentosus OM13 only). Within the third day of fermentation, the pH of the brines decreased significantly, reaching pH 4.85 for trial three, pH 5.15 for trial two, and pH 5.92 for trial one. The pH of both controls decreased more slowly, and had values below pH 5.0 only after the fifteenth day of fermentation (control one) and the sixty-fifth day of fermentation (control two). Trial three reached the highest lactic acid bacteria (LAB) concentration on the third day of fermentation. After six days of fermentation, all trials showed similar values of LAB counts that were significantly higher compared to control number one. The result from genotypic identification showed that L. pentosus OM13 was the most frequently isolated in the inoculated trials. Lactobacillus plantarum, Lactobacillus coryniformis and Pediococcus pentosaceous were also detected at very low concentrations. Homoguaiacol, 2-butanol, 4-ethylphenol, phenylethyl alcohol and 4-ethylphenol were the volatile organic compounds detected at the highest levels in all experimental trials. Trial three showed a higher concentration of squalene that was not detected in other trials. The highest sensory scores of green olive aroma and overall satisfaction were found for all experimental olives, especially for those of trial one and trial two, that differed significantly from the untreated controls. This study provides evidence that the addition of lactic acid, nutrient adjuvants and, most importantly, the acclimatization of LAB cells significantly shortens the acidification process of olive brine, and improves safety and sensory quality. Shorter acidification processes result in a more rapid transformation of table olives, with reduced commodity loss and lower costs of production compared to conventional manufacturing protocols.

AB - The thioredoxin system protects against oxidative stress through the reversible oxidation of the thioredoxin active center dithiol to a disulphide. The genome of Oenococcus oeni PSU-1 contains three thioredoxin genes (trxA1, trxA2, trxA3), one thioredoxin reductase (trxB) and one ferredoxin reductase (fdr) which, until recently, was annotated as a second thioredoxin reductase. For the first time, the entire thioredoxin system in several O. oeni strains isolated from wine has been analysed. Comparisons at the DNA and protein levels have been undertaken between sequences from O. oeni and other genera and species, and the genera Leuconostoc and Lactobacillus were found to present the highest similarities. The gene most frequently absent from a collection of 34 strains and the sequences annotated in the NCBI database was trxA1. Moreover, phylogenetic analysis suggested that this gene was horizontally transferred from Lactobacillus to O. oeni. Strain-dependent expression profiles were determined in rich and in wine like media. General over-expression was detected after inoculation into wine-like medium, with trxA3 being the most highly expressed gene. The increased transcriptional levels of the thioredoxin genes are indicative of the crucial role of this system in the O. oeni response to wine harsh conditions. PMID- 27697167 TI - Advances in the genomics and metabolomics of dairy lactobacilli: A review. AB - The Lactobacillus genus represents the largest and most diverse genera of all the lactic acid bacteria (LAB), encompassing species with applications in industrial, biotechnological and medical fields. The increasing number of available Lactobacillus genome sequences has allowed understanding of genetic and metabolic potential of this LAB group. Pangenome and core genome studies are available for numerous species, demonstrating the plasticity of the Lactobacillus genomes and providing the evidence of niche adaptability. Advancements in the application of lactobacilli in the dairy industry lie in exploring the genetic background of their commercially important characteristics, such as flavour development potential or resistance to the phage attack. The integration of available genomic and metabolomic data through the generation of genome scale metabolic models has enabled the development of computational models that predict the behaviour of organisms under specific conditions and present a route to metabolic engineering. Lactobacilli are recognised as potential cell factories, confirmed by the successful production of many compounds. In this review, we discuss the current knowledge of genomics, metabolomics and metabolic engineering of the prevalent Lactobacillus species associated with the production of fermented dairy foods. In depth understanding of their characteristics opens the possibilities for their future knowledge-based applications. PMID- 27697168 TI - Artisanal Italian salami and soppresse: Identification of control strategies to manage microbiological hazards. PMID- 27697169 TI - The microbiology of beef carcasses and primals during chilling and commercial storage. AB - The primary objective of this study was to characterise (microbiology and physical parameters) beef carcasses and primals during chilled storage. A minor aim was to compare observed growth of key spoilage bacteria on carcasses with that predicted by ComBase and the Food Safety Spoilage Predictor (FSSP). Total viable count (TVC), total Enterobacteriacae count (TEC), Pseudomonas spp., lactic acid bacteria (LAB), Brochothrix thermosphacta and Clostridium spp. were monitored on beef carcasses (n = 30) and primals (n = 105) during chilled storage using EC Decision 2001/471/EC and ISO sampling/laboratory procedures. The surface and/or core temperature, pH and water activity (aw) were also recorded. Clostridium (1.89 log10 cfu/cm2) and Pseudomonas spp. (2.12 log10 cfu/cm2) were initially the most prevalent bacteria on carcasses and primals, respectively. The shortest mean generation time (G) was observed on carcasses with Br. thermosphacta (20.3 h) and on primals with LAB (G = 68.8 h) and Clostridium spp. (G = 67 h). Over the course of the experiment the surface temperature decreased from 37 degrees C to 0 degrees C, pH from 7.07 to 5.65 and aw from 0.97 to 0.93 The observed Pseudomonas spp. and Br. thermosphacta growth was more or less within the range of predictions of Combase. In contrast, the FSSP completely overestimated the growth of LAB. This study contributes to the very limited microbiological data on beef carcasses and primals during chilling. PMID- 27697170 TI - Bacterial microbiota profile in gills of modified atmosphere-packaged oysters stored at 4 degrees C. AB - As filter-feeding bivalves, oysters can accumulate microorganisms into their gills, causing spoilage and potential safety issues. This study aims to investigate the changes in the gill microbiota of oysters packed under air and modified atmospheres (MAs, 50% CO2: 50% N2, 70% CO2: 30% O2, and 50% CO2: 50% O2) during storage at 4 degrees C. The diversity of bacterial microbiota in oyster gills was profiled through polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis on the 16S rRNA gene V3 region to describe the variation during the entire storage period. The DGGE profile revealed high bacterial diversity in the air- and MA-packaged oyster gills, and the spoilage bacterial microbiota varied in the MA-packaged oyster gills. Results indicated that CO2:O2 (70%:30%) was suitable for oyster MA packaging and that high bacterial loads in oyster gills need to be considered during storage. In addition, Lactobacillus and Lactococcus species were found to grow dominantly in fresh oyster gills under MA packaging, which supports the potential application of MA packaging for oyster storage. PMID- 27697171 TI - Survival of Streptococcus suis, Streptococcus dysgalactiae and Trueperella pyogenes in dry-cured Iberian pork shoulders and loins. AB - Dry-cured hams, shoulders and loins of Iberian pigs are highly appreciated in national and international markets. Salting, additive addition and dehydration are the main strategies to produce these ready-to-eat products. Although the dry curing process is known to reduce the load of well-known food borne pathogens, studies evaluating the viability of other microorganisms in contaminated pork have not been performed. In this work, the efficacy of the dry curing process to eliminate three swine pathogens associated with pork carcass condemnation, Streptococcus suis, Streptococcus dysgalactiae and Trueperella pyogenes, was evaluated. Results of this study highlight that the dry curing process is a suitable method to obtain safe ready-to-eat products free of these microorganisms. Although salting of dry-cured shoulders had a moderate bactericidal effect, results of this study suggest that drying and ripening were the most important stages to obtain dry-cured products free of these microorganisms. PMID- 27697172 TI - Prokaryotic community composition in alkaline-fermented skate (Raja pulchra). AB - Prokaryotes were extracted from skates and fermented skates purchased from fish markets and a local manufacturer in South Korea. The prokaryotic community composition of skates and fermented skates was investigated using 16S rRNA pyrosequencing. The ranges for pH and salinity of the grinded tissue extract from fermented skates were 8.4-8.9 and 1.6-6.6%, respectively. Urea and ammonia concentrations were markedly low and high, respectively, in fermented skates compared to skates. Species richness was increased in fermented skates compared to skates. Dominant and predominant bacterial groups present in the fermented skates belonged to the phylum Firmicutes, whereas those in skates belonged to Gammaproteobacteria. The major taxa found in Firmicutes were Atopostipes (Carnobacteriaceae, Lactobacillales) and/or Tissierella (Tissierellaceae, Tissierellales). A combination of RT-PCR and pyrosequencing for active bacterial composition showed that the dominant taxa i.e., Atopostipes and Tissierella, were active in fermented skate. Those dominant taxa are possibly marine lactic acid bacteria. Marine bacteria of the taxa Lactobacillales and/or Clostridia seem to be important in alkaline fermentation of skates. PMID- 27697173 TI - Effect of bioaugmented inoculation on microbiota dynamics during solid-state fermentation of Daqu starter using autochthonous of Bacillus, Pediococcus, Wickerhamomyces and Saccharomycopsis. AB - Daqu, a traditional fermentation starter that is used for Chinese liquor and vinegar production, is still manufactured through a traditional spontaneous solid state fermentation process with no selected microorganisms are intentionally inoculated. The aim of this work was to analyze the microbiota dynamics during the solid-state fermentation process of Daqu using a traditional and bioaugmented inoculation with autochthonous of Bacillus, Pediococcus, Saccharomycopsis and Wickerhamomyces at an industrial scale. Highly similar dynamics of physicochemical parameters, enzymatic activities and microbial communities were observed during the traditional and bioaugmented solid-state fermentation processes. Both in the two cases, groups of Streptophyta, Rickettsiales and Xanthomonadales only dominated the first two days, but Bacillales and Eurotiales became predominant members after 2 and 10 days fermentation, respectively. Phylotypes of Enterobacteriales, Lactobacillales, Saccharomycetales and Mucorales dominated the whole fermentation process. No significant difference (P > 0.05) in microbial structure was observed between the traditional and bioaugmented fermentation processes. However, slightly higher microbial richness was found during the bioaugmented fermentation process after 10 days fermentation. Our results reinforced the microbiota dynamic stability during the solid-state fermentation process of Daqu, and might aid in controlling the traditional Daqu manufacturing process. PMID- 27697174 TI - Postharvest biocontrol ability of killer yeasts against Monilinia fructigena and Monilinia fructicola on stone fruit. AB - The antagonistic effects of Debaryomyces hansenii KI2a, D. hansenii MI1a and Wickerhamomyces anomalus BS91 were tested against Monilinia fructigena and Monilinia fructicola in in vitro and in vivo trials. All yeast strains demonstrated antifungal activity at different levels depending on species, strain and pathogen. D hansenii KI2a and W. anomalus BS91 showed the highest biocontrol activity in vitro; the production of hydrolytic enzymes, killer toxins and volatile organic compounds (VOCs) were hypothesized as their main mechanisms of action against pathogens. D hansenii KI2a and W. anomalus BS91 significantly reduced brown rot incidence and severity on peach and plum fruits artificially inoculated with M. fructigena and M. fructicola, especially when applied 24 h before pathogen inoculation. On the opposite, D. hansenii MI1a exhibited weak antagonistic activity towards M. fructigena on peach and plum fruits and was ineffective against M. fructicola. The noticeable ability of W. anomalus BS91 to control brown rot could be also correlated with its high capacity to colonize the wound tissue and to increase its population density. Accordingly, the antagonistic strains of D. hansenii and W. anomalus could be proposed as active ingredients for the development of biofungicides against Monilinia species that are responsible for considerable economic losses in stone fruit crops.

The authors of "Subsequent Shoulder Surgery Following Isolated Arthroscopic SLAP Repair" reveal that 1 in 10 people needed additional surgery within 3 years after SLAP repair-mainly for disorders of the rotator cuff, biceps, and distal clavicle. This underscores the fact that SLAP tears rarely occur in isolation and that the initial diagnosis and management may require more than just SLAP work.

AB - Is a biomechanical cadaveric study to assess the effect of rotator cuff tear size and repair technique on supraspinatus muscle stiffness clinically relevant? A study in this issue compared double-row and knotless transosseous-equivalent repairs, but notably, muscle loading was not simulated. Results showed that the knotless transosseous-equivalent repair for larger tears demonstrated a more uniform stiffness distribution across the supraspinatus muscle compared with the double-row repair. However, given the inherently asymmetrical functional anatomy and morphology of the supraspinatus tendon-muscle unit, when muscle tone exists, the effect of the repair technique on muscle stiffness in vivo may not be determined based on the findings of this study.

The challenge is compounded by limited treatment options and high patient expectations, with patients often desiring a return to impact high intensity activity. Distal femoral osteotomy has been reported to be one potential treatment option; however, a highly heterogeneous literature exists for both opening and closing wedge distal femoral osteotomies for the treatment of isolated lateral compartment osteoarthritis with valgus malalignment. The literature does not provide significant direction for surgeons on the appropriate surgical approach; however, opening wedge osteotomies allow for fine adjustment and maintain leg length and joint alignment, and are our preferred approach.

PMID- 27697193 TI - Outcomes after repeat hepatic resection for recurrent metastatic colorectal cancer: A population-based study. AB - BACKGROUND: More than half of the patients undergoing resection for colorectal cancer liver metastases develop recurrent hepatic disease. We report management and outcomes of patients undergoing repeat hepatectomy in routine practice. METHODS: All cases of repeat hepatectomy for colorectal cancer liver metastases from 2002 to 2009 in the Canadian Province of Ontario were identified using the population-based Ontario Cancer Registry and linked treatment records. RESULTS: Of 1,310 patients who underwent resection of CRLM, 78 (6.0%) underwent a repeat liver resection. Mean age was 56 years and the median time between resections was 19 months. Compared with the first resection, second resections were associated with fewer lesions (2.7 vs 1.5; P = .001) and fewer major resections (58% vs 31%; P = .024). The size of largest lesion, positive margin rate, length of hospital stay, and 90-day mortality were similar. Unadjusted 5-year overall survival from the time of second resection was 45% (95% confidence interval = 32% to 59%) and cancer-specific survival was 47% (95% confidence interval = 30% to 64%). CONCLUSIONS: Repeat liver resections for metastatic CRC involve fewer lesions and less extensive surgery and a substantial proportion of patients achieve long-term survival.

AB - BACKGROUND: Alcoholic ketoacidosis (AKA) is a complex syndrome that results from disrupted metabolism in the setting of excessive alcohol use and poor oral intake. Dehydration, glycogen depletion, high redox state, and release of stress hormones are the primary factors producing the characteristic anion gap metabolic acidosis with an elevated beta-hydroxybutyrate (beta-OH) and lactate. CASE REPORT: We present the case of a 47-year-old man who presented to the emergency department with metabolic acidosis and profoundly elevated lactate levels who had AKA. He recovered completely with intravenous fluids and parenteral glucose administration. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should always consider the immediately life-threatening causes of a severe anion gap metabolic acidosis and treat aggressively based on the situation. This case highlights the fact that AKA can present with an impressively elevated lactate levels. Emergency physicians should keep AKA in the differential diagnosis of patients who present with a similar clinical picture.

AB - The pituitary gonadotrope is central to reproductive function. Gonadotropes develop in a systematic process dependent on signaling factors secreted from surrounding tissues and those produced within the pituitary gland itself. These signaling pathways are important for stimulating specific transcription factors that ultimately regulate the expression of genes and define gonadotrope identity. Proper gonadotrope development and ultimately gonadotrope function are essential for normal sexual maturation and fertility. Understanding the mechanisms governing differentiation programs of gonadotropes is important to improve treatment and molecular diagnoses for patients with gonadotrope abnormalities. Much of what is known about gonadotrope development has been elucidated from mouse models in which important factors contributing to gonadotrope development and function have been deleted, ectopically expressed, or modified. This chapter will focus on many of these mouse models and their contribution to our current understanding of gonadotrope development. PMID- 27697201 TI - Clinical Applications of Gonadotropins in the Male. AB - The pituitary gonadotropins, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) play a pivotal role in reproduction. The synthesis and secretion of gonadotropins are regulated by complex interactions among several endocrine, paracrine, and autocrine factors of diverse chemical structure. In men, LH regulates the synthesis of androgens by the Leydig cells, whereas FSH promotes Sertoli cell function and thereby influences spermatogenesis. Gonadotropins are complex molecules composed of two subunits, the alpha- and beta-subunit, that are noncovalently associated. Gonadotropins are decorated with glycans that regulate several functions of the protein including folding, heterodimerization, stability, transport, conformational maturation, efficiency of heterodimer secretion, metabolic fate, interaction with their cognate receptor, and selective activation of signaling pathways. A number of congenital and acquired abnormalities lead to gonadotropin deficiency and hypogonadotropic hypogonadism, a condition amenable to treatment with exogenous gonadotropins. Several natural and recombinant preparations of gonadotropins are currently available for therapeutic purposes. The difference between natural and the currently available recombinant preparations (which are massively produced in Chinese hamster ovary cells for commercial purposes) mainly lies in the abundance of some of the carbohydrates that conform the complex glycans attached to the protein core. Whereas administration of exogenous gonadotropins in patients with isolated congenital hypogonadotropic hypogonadism is a well recognized therapeutic approach, their role in treating men with normogonadotropic idiopathic infertility is still controversial. This chapter concentrates on the main structural and functional features of the gonadotropin hormones and how basic concepts have been translated into the clinical arena to guide therapy for gonadotropin deficit in males. PMID- 27697202 TI - Beyond Reproduction: Pituitary Hormone Actions on Bone. AB - The long-held belief that pituitary hormones act solely on master targets was first questioned when we documented G protein-coupled receptors for thyroid stimulating hormone, follicle-stimulating hormone, adrenocorticotrophic hormone, oxytocin, and vasopressin on bone cells. These evolutionarily conserved hormones and their receptors are known to have primitive roles, and exist in invertebrate species as far down as coelenterates. It is not surprising therefore that each such hormone has multiple hitherto unrecognized functions in mammalian integrative physiology, and hence, becomes a potential target for therapeutic intervention. Here we discuss the skeletal actions of pituitary hormones. PMID- 27697203 TI - Gonadotrope Tumors. AB - Gonadotrope tumors arise from the gonadotropes of the adenohypophysis. These cells rarely give rise to hyperplasia, usually only in the setting of long standing premature gonadal failure. In contrast, gonadotrope tumors represent one of the most frequent types of pituitary tumors. Despite their relatively common occurrence, the pathogenesis of gonadotrope tumors remains unknown. Effective nonsurgical therapies remain out of reach. We review the pituitary gonadotrope from the morphologic and functional perspectives to better understand its involvement as the cell of origin of a frequent type of pituitary tumor. PMID- 27697204 TI - Mouse Models for the Study of Synthesis, Secretion, and Action of Pituitary Gonadotropins. AB - Gonadotropins play fundamental roles in reproduction. More than 30years ago, Cga transgenic mice were generated, and more than 20years ago, the phenotypes of Cga null mice were reported. Since then, numerous mouse strains have been generated and characterized to address several questions in reproductive biology involving gonadotropin synthesis, secretion, and action. More recently, extragonadal expression, and in some cases, functions of gonadotropins in nongonadal tissues have been identified. Several genomic and proteomic approaches including novel mouse genome editing tools are available now. It is anticipated that these and other emerging technologies will be useful to build an integrated network of gonadotropin signaling pathways in various tissues. Undoubtedly, research on gonadotropins will continue to provide new knowledge and allow us transcend from benchside to the bedside. PMID- 27697206 TI - Preface. PMID- 27697205 TI - Clinical Applications of Gonadotropins in the Female: Assisted Reproduction and Beyond. AB - Gonadotropins (LH, FSH, and hCG) act in concert in the regulation of female reproductive system. Exploiting this influence, they are part of the assisted reproductive technique protocols. In this review we analyze the effectiveness of the different available gonadotropin formulations and the consequent adverse events. Moreover, different protocols for poor-responders and polycystic ovary syndrome affected women are explored. All these clinical different approaches have specific molecular bases, covered in this review starting from evolution and population genetics, getting to in vitro studies of gonadotropins action. Beyond their application in assisted reproductive technique, gonadotropins have also been largely studied for their intertwined network of interactions with other hormones, which all together contribute to the functioning of the reproductive system and other hormonal axes. In particular, there is both clinical and molecular evidence of interaction between thyroid hormones and insulin growth factors with gonadotropins. Finally, gonadotropins are widely studied for their role in the maintenance of the proper balance between cell proliferation and differentiation, and therefore in cancer. PMID- 27697207 TI - Brown adipose tissue. PMID- 27697208 TI - The rediscovery of BAT in adult humans using imaging. AB - Human brown adipose tissue has been acknowledged in newborns and children but in adults the first printed publications are from the beginning of 20th century. Further evidence of the existence of adult brown fat was published throughout the century but only very recently the functionality of active brown adipose tissue in vivo in adulthood was confirmed. This was contributed mainly by advanced imaging technology, namely hybrid positron emission tomography (PET) and computed tomography (CT), being able to combine functional and anatomical imaging data. Functionality is most commonly measured with glucose analog, 18F-fluoro-2-deoxy-d glucose (FDG) but other tracers for other functions than glucose uptake have been introduced as well. Growing body of evidence has increased the knowledge of the role of brown adipose tissue in human metabolism and energy expenditure, providing a promising option for the management of body weight balance and disturbed glucose and lipid metabolism. PMID- 27697209 TI - Browning and thermogenic programing of adipose tissue. AB - The view of adipose tissue as solely a fat storing organ has changed significantly over the past two decades with the discoveries of numerous adipocyte-secreted factors, so called adipokines, and their endocrine functions throughout the body. The newest chapter added to this story is the finding that adipose tissue is also a thermogenic organ contributing to energy expenditure through actions of specialized, heat-producing brown or beige adipocytes. In contrast to bone fide brown adipocytes, beige cells develop within white fat depots in response to various stimuli such as prolonged cold exposure, underscoring the great thermogenic plasticity of adipose tissue. The energy dissipating properties of beige and/or brown adipocytes hold great promise as a novel therapeutic concept against obesity and related complications. Hence, identifying the specific thermogenic adipocyte populations in humans and their pathways of activation are key milestones of current metabolism research. Here we will discuss the recent advances in the understanding of the molecular and physiological mechanisms of adipose tissue browning. PMID- 27697210 TI - Implications of thermogenic adipose tissues for metabolic health. AB - Excess and ectopic fat accumulation in obesity is a major risk factor for developing hyperlipidemia, type 2 diabetes and cardiovascular disease. The activation of brown and/or beige adipocytes is a promising target for the treatment of metabolic disorders as the combustion of excess energy by these thermogenic adipocytes may help losing weight and improving plasma parameters including triglyceride, cholesterol and glucose levels. The regulation of heat production by thermogenic adipose tissues is based on a complex crosstalk between the autonomous nervous system, intracellular and secreted factors. This multifaceted alignment regulates thermogenic demands to environmental circumstances in dependence on available energy resources. This review summarizes the current knowledge how thermogenic tissues can be targeted to combat the burden of diseases with a special focus on lipid metabolism and diseases related to lipoprotein metabolism. PMID- 27697211 TI - The role of BAT in cardiometabolic disorders and aging. AB - The demonstration of the presence of metabolically active brown adipose tissue (BAT) in adult humans using positron emission tomography (PET) over the past decade has lead to the rapid development of our knowledge regarding the role of BAT in energy metabolism in animal models and in humans. Although animal models continue to provide highly valuable information regarding the mechanisms regulating BAT development, mass and metabolic functions, these studies led to many assumptions that have been at best only partially verified in humans so far. Combined to some limitations of the current investigation approaches used in humans, this has lead to speculation on the potential role of BAT dysfunction in the development of cardiometabolic disorders and on the potential of BAT metabolic activation to treat these conditions. Here we propose a critical review of the evidence for the implication of BAT in cardiometabolic health. PMID- 27697212 TI - Hormonal and nutritional signalling in the control of brown and beige adipose tissue activation and recruitment. AB - Recent research has revealed that the activity of adipose tissue (BAT) in adult humans is higher than previously thought, and that obese patients show abnormally low levels of brown fat activity. Studies in experimental animals have shown that BAT is a site of energy expenditure, and that BAT activity protects against obesity and associated metabolic diseases. The action of the sympathetic nervous activity on BAT depots is considered the main regulator of BAT activity in rodent models and possibly also in humans. However, recent research has revealed the existence of additional hormonal factors, produced by distinct peripheral tissues or present in the diet, that influence the amount and activity of BAT. These hormonal factors may act on BAT directly, but also indirectly by targeting the brain and determining the intensity of sympathetic action upon BAT. Identification and characterization of novel factors that control BAT may provide clues for the development of new strategies to treat obesity and metabolic diseases. PMID- 27697213 TI - Estradiol and brown fat. AB - Ovarian steroids, such as estradiol (E2), control a vastness of physiological processes, such as puberty, reproduction, growth, development and metabolic rate. In fact, physiological, pathological, pharmacological or genetically-induced estrogen deficiency causes increased appetite and reduced energy expenditure, promoting weight gain and ultimately leading to obesity. Remarkably, estrogen replacement reverts those effects. Interestingly, although a wealth of evidence has shown that E2 can directly modulate peripheral tissues to exert their metabolic actions, novel data gathered in recent years have shown that those effects are mainly central and occur in the hypothalamus. Here, we will review what is known about the actions of E2 on energy homeostasis, with particular focus on brown adipose tissue (BAT) thermogenesis. PMID- 27697214 TI - Activation and recruitment of brown adipose tissue by cold exposure and food ingredients in humans. AB - Since the recent re-discovery of brown adipose tissue (BAT) in adult humans, this thermogenic tissue has attracted increasing interest. The inverse relationship between the BAT activity and body fatness suggests that BAT, because of its energy dissipating activity, is protective against body fat accumulation. Cold exposure activates and recruits BAT in association with increased energy expenditure and decreased body fatness. The stimulatory effects of cold are mediated through transient receptor potential channels (TRP), most of which are also chemesthetic receptors for various food ingredients. In fact, capsaicin and its analog capsinoids, representative agonists of TRPV1, mimic the effects of cold to decrease body fatness through the activation and recruitment of BAT. The anti-obesity effect of some other food ingredients including tea catechins may also be attributable to the activation of the TRP-BAT axis. Thus, BAT is a promising target for combating obesity and related metabolic disorders in humans. PMID- 27697215 TI - Differential expression of toll-like receptors in the human placenta across early gestation. AB - Toll-like receptors (TLRs) are an essential component of the innate immune system. While a number of studies have described TLR expression in the female reproductive tract, few have examined the temporal expression of TLRs within the human placenta. We hypothesized that the pattern of TLR expression in the placenta changes throughout the first and second trimester, coincident with physiological changes in placental function and the demands of innate immunity. We collected first and second trimester placental tissue and conducted quantitative PCR analysis for TLRs 1-10, followed by immunohistochemistry to define the cell specific expression pattern of a subset of these receptors. Except for the very earliest time points, RNA expression for TLRs 1-10 was stable out to 20 weeks gestation. However, the pattern of protein expression evolved over time. Early first trimester placenta demonstrated a strong, uniform pattern predominantly in the inner villous cytotrophoblast layer. As the placenta matured through the second trimester, both the villous cytotrophoblasts and the pattern of TLR expression within them became disorganized and patchy, with putative Hofbauer cells now identifiable in the tissue also staining positive. We conclude from this data that placental TLR expression changes over the course of gestation, with a tight barrier of TLRs forming a wall of defense along the cytotrophoblast layer in the early first trimester that breaks down as pregnancy progresses. These data are relevant to understanding placental immunity against pathogen exposure throughout pregnancy and may aid in our understanding of the vulnerable period for fetal exposure to pathogens. PMID- 27697217 TI - Placental exosomes and pre-eclampsia: Maternal circulating levels in normal pregnancies and, early and late onset pre-eclamptic pregnancies. AB - INTRODUCTION AND AIM: Exosomes are a subtype of extracellular vesicle (20-130 nm) released by biological cells under normal and pathological conditions. Although there have been reports of circulating exosomes in normal pregnancy, the relevance of placental-derived exosomes in normal and abnormal pregnancies still needs to be elucidated. The aim of this study was to quantify total and placental derived exosomes in maternal plasma from normal (N), early onset- and late onset preeclampsia (PE). METHOD: Plasma samples were obtained from pregnant women in the third trimester, for the isolation of exosomes by differential ultracentrifugation. Total exosomes were quantified using nanoparticle tracking analysis and immuno-reactive exosomal CD63 quantification. Placental-derived exosomes were quantified using placental alkaline phosphatase (PLAP) as a specific marker. The contribution of placental-derived exosomes to total exosomes in maternal plasma was determined by the ratio of PLAP+ exosomes to CD63+ exosomes. RESULTS: The concentration of total exosomes significantly increased in early onset-PE and late onset-PE compared to N (<=33 weeks) and N (>=34 weeks). The relative concentration of placental-derived exosomes significantly increased in early onset-PE but decreased in late onset-PE compared to N. The ratio of PLAP+ exosomes to total number of exosomes significantly decreased in early onset PE and late onset-PE. A positive correlation between total and placental-derived exosomes were obtained in N (<=33 weeks: Pearson's r = 0.60, >=34 weeks: Pearson's r = 0.67) and early onset-PE (Pearson's r = 0.51, p < 0.05) with the inverse in late onset-PE (Pearson's r = -0.62, p < 0.01). CONCLUSION: The differences in the contribution of placental-derived exosomes to total exosomes in maternal circulation suggests a possible pathophysiological role of placental derived exosomes in pre-eclampsia. PMID- 27697216 TI - Effect of selective fetectomy on morphology of the mouse placenta. AB - INTRODUCTION: Placental examination is recommended when genetic mutations cause fetal lethality in mice. But how fetal death alters histomorphology of the surviving mouse placenta is not known. METHODS: Placentas were examined at E17.5 after fetectomy of 1-2 fetal mice per pregnancy at either embryonic day (E) 15.5 (N = 8; Fx-2 group) or E13.5 (N = 5; Fx-4 group), which left 12 +/- 2 surviving fetuses per litter. RESULTS: Fetectomy caused no changes in placental weights and no increases in placental hypoxia (pimonidazole staining). The size and cell morphology of the decidua and junctional zone regions were unchanged and, in the Fx-2 group, these regions became significantly less hypoxic. Significant changes in labyrinth volume included a 30% increase in the Fx-2 group and in both groups, a >50% decrease in % fetal blood space and >40% increase in % labyrinth tissue. Maternal blood sinusoid volume was unchanged. Cell death in the labyrinth was significantly increased (22-fold increase in TUNEL staining) whereas placental mRNA expression of the proliferation marker Mki67 was unchanged. mRNA expression of sFlt1 and Prl3b1 (mPL-II) was unchanged in the labyrinth and junctional zone tissues in the Fx-2 group and in whole placental tissue in the Fx-4 group. DISCUSSION: Placental examination of the junctional zone and decidual regions after spontaneous fetal death in late gestation is likely to yield useful phenotypic information and abnormalities that may contribute to fetal death. In contrast, labyrinth abnormalities including increased tissue volume and reduced fetoplacental vascularity may not be due to genetic perturbation nor predate fetal death. PMID- 27697218 TI - Vasoactivity of the rat endovascular trophoblast. AB - INTRODUCTION: Rat endovascular trophoblasts (EVasT) express smooth muscle (SM) proteins and contract ex vivo upon exposure to endothelin-1 (ET1) via receptors A and B (ETA, ETB). Presently, we investigated the EVasT response to NOS inhibition (N-Nitro-l-arginine methyl ester hydrochloride, l-NAME), and potentiation by NO donor [S-Nitroso-N-Acetyl-D,l-Penicillamine (SNAP)] following KCl precontraction. M&M: Luminal surface area (LSA) of remodeled spiral artery rings (SAR) devoid of SM was measured ex vivo upon exposure to l-NAME alone; l-NAME and ET1 representing the combined contractile effect of both ET1 receptors; l-NAME with ET1 and ETA antagonist, representing the isolated contractile effect via ETB. In another experiment we administered SNAP to KCl precontracted SAR. Statistical analysis was performed using 2-way mixed ANOVA and repeated measures. RESULTS: l NAME reduced LSA by 2.22%, 95% CI [0.83%, 3.60%] compared with control. ET1 and l NAME reduced LSA immediately, compared with a plateau at 60min by ET1 alone. The isolated ET1 constrictive effect via ETB, reduced LSA by 5.94%; 95% CI [3.47%, 8.41%], significantly more than that obtained via ETA following 36 min of the experiment by 0.88%; 95%CI [0.09%, 1.67%]. Addition of KCl reduced LSA by 11.9%, 95% CI [9.6%, 14.1%]. Addition of SNAP increased LSA by 3.0%, 95% CI [1.7%, 4.3%]. CONCLUSIONS: EVasT of the rat remodeled spiral artery react to ET1 and KCl similar to vascular SM: contract via both ET1 receptors and KCl and relax by ET1 via ETB and by SNAP. This phenomenon may play a role in rat models of gestational vasoactive systems dysregulation. PMID- 27697220 TI - Upregulation of VEGF by small activating RNA and its implications in preeclampsia. AB - INTRODUCTION: Preeclampsia is a severe pregnancy complication mostly due to inadequate vascular dilation and remodeling of spiral arteries. VEGF, the major factor for angiogenesis, is necessary for modulating angiogenic processes in the placenta. Hence reduction of VEGF in gestational hypertension may also lead to hypoperfusion and subsequent hypoxia of the fetus in hypertensive pregnancy. METHODS: This study aimed at elucidating the mechanism of action of VEGF in preeclampsia. Small activating RNAs (saRNA) were used to upregulate VEGF expression in human trophoblast cells (HTR-8/SVneo). The VEGF expression level was analyzed by real-time quantitative PCR and western blot, while its transfection efficiency was measured by flow cytometer assay. Cell migration was analyzed by a wound scratch assay. NO secretion was detected by determining NO metabolites. eNOS expression was analyzed by western blot. Tube formation function of cells was then analyzed by matrigel migration assay. RESULTS: VEGF expression significantly increased after saRNA transfection (all p < 0.05). NO secretion and eNOS expression significantly increased by saRNA in HTR-8/SVneo cells (p = 0.0003 and 0.032 respectively). The migration ability and tube formation function of HTR-8/SVneo cells were enhanced by saRNA (p = 0.024 and 0.013 respectively). TNF-alpha inhibited VEGF-downstream eNOS-NO pathway activity as well as cell migration and tubulogenesis, while enforcing the expression of VEGF attenuated all the insults induced by TNF-alpha. CONCLUSIONS: Utilizing an RNA activation strategy to increase endogenous VEGF expression could be an emerging and effective approach for the treatment of preeclampsia. PMID- 27697219 TI - A new biological and clinical resource for research into pregnancy complications: The Baby Bio Bank. AB - About 20% of pregnancies are affected by some form of complication. Research has shown that anomalies in implantation, development, and growth of the fetus; ineffective nutrient exchange between mother and fetus due to placental dysfunction; and maternal problems such as hypertension or infection during pregnancy can all lead to adverse pregnancy outcomes. However, the molecular aetiology of such events remains poorly understood. Fetal growth restriction (FGR), recurrent miscarriage (RM), preterm birth (PTB), and pre-eclampsia (PE) are the most common pregnancy complications encountered in the UK and these outcomes can result in an array of morbidities in both mother and baby, and in the most severe cases in mortality. We need to know more about normal pregnancy and where the important triggers are for failure. This prompted us to collect a large set of biological samples with matching clinical data from over 2500 normal and abnormal pregnancies, for use in research into these conditions. This paper outlines the nature of these sample sets and their availability to academia and industry, with the intention that their widespread use in research will make significant contributions to the improvement of maternal and fetal health worldwide (http://www.ucl.ac.uk/tapb/sample-and-data-collections-at-ucl/biobanks ucl/baby-biobank). PMID- 27697221 TI - Quality of placental RNA: Effects of explant size and culture duration. AB - We evaluated the impact of placental micro (<=50 mg) and macro (~200 mg) explants, oxygen concentration and culture method on placental RNA quality after long-term culture. Our findings show that micro explants cultured at 8% oxygen have the best RNA quality and tissue structure. Macro explants were less viable after long-term culture. Macro explants and explants undergoing syncytial degeneration produced poor quality RNA and should be avoided. PMID- 27697223 TI - Compartmentalized localization of 11beta-HSD 1 and 2 at the feto-maternal interface in the first trimester of human pregnancy. AB - Glucocorticoids are engaged in a number of actions at the feto-maternal interface for the establishment of early pregnancy. However, excessive glucocorticoids can be deleterious to fetal development. Therefore, compartmentalized distribution of 11beta-hydroxysteroid dehydrogenase 1 and 2 (11beta-HSD1 and 2), which regenerates and inactivates cortisol respectively, would ensure an optimal cortisol concentration at the feto-maternal interface for the establishment of early gestation. However, the distribution pattern of 11beta-HSD1 and 2 at the feto-maternal interface in early human pregnancy is not clearly defined. Here we showed that 11beta-HSD1 distributed extensively on the maternal side including decidual stromal cells and epithelial cells but scarcely on the fetal side except for localization in the fetal blood vessels of the chorionic villi. In contrast, 11beta-HSD2 was abundantly localized in syncytial layer of the chorionic villi and the decidual epithelium. In primary cultures, cortisol upregulated not only 11beta-HSD1 expression in decidual stromal cells but also 11beta-HSD2 expression in villous trophoblasts of early pregnancy. Further studies revealed that cortisol inhibited the expression of interleukin-1beta and 6 in decidual stromal cells and villous trophoblasts, and stimulated expression of human chorionic gonadotropin in villous trophoblasts. Collectively, this study has revealed a compartmentalized distribution pattern of 11beta-HSD 1 and 2 at the feto-maternal interface, both of which can be upregulated by glucocorticoids, suggesting that a coordinated interaction between 11beta-HSD 1 and 2 may exist to ensure an optimal cortisol concentration at discrete locations at the feto-maternal interface for the establishment of early pregnancy. PMID- 27697222 TI - Modulation of FABP4 hypomethylation by DNMT1 and its inverse interaction with miR 148a/152 in the placenta of preeclamptic rats and HTR-8 cells. AB - Inflammation and dysregulated lipid metabolism are involved in the pathogenesis of preeclampsia, and fatty acid binding protein 4 (FABP4) is known to regulate both inflammation and lipid metabolism. In the present study, we elucidated the role of FABP4 using in vitro and in vivo models of preclampsia. We found increased expression of FABP4 in the placenta of preeclamptic rats, which was further confirmed in HTR-8 cells, an extravillous trophoblast cell line, treated with L-NAME. Overexpression of FABP4 in HTR-8 cells resulted in upregulated expression of pro-inflammatory cytokines IL-6 and TNF-alpha, and increased lipid accumulation, suggesting that FABP4 plays a role in preeclampsia. Furthermore, downregulation of methylation in the promotor resulted in increased FABP4 expression, which was mediated by downregulated DNA methyltransferase 1 (DNMT1). Bioinformatics analysis showed that miR-148a/152 regulated the expression of DNMT1, and additional in vitro studies revealed that miR-148a/152 inhibited DNMT1 expression by directly binding to its 3'-UTR. Interestingly, DNMT1 enhanced the expression of miR-148a/152 by downregulation of methylation in its promotor. Taken together, our results showed that FABP4 may be involved in the pathogenesis of preeclampsia, and the expression of FABP4 is enhanced by miR-148a/152 mediated inhibition of DNMT1 expression. PMID- 27697224 TI - Placental histological examination and the relationship with oxidative stress in preterm infants. AB - BACKGROUND: Prenatal conditions of enhanced oxidative stress (OS) linked to inflammation or hypoxia have been associated with impaired fetal growth and preterm delivery. Little is known regarding biomarkers of OS in the cord blood of preterm infants and placental histological patterns. OBJECTIVES: To test the hypothesis that placental lesions indicating chorioamnionitis (CA) or vascular underperfusion (VU) are associated with increased OS in the offspring. METHODS: 120 neonates born below 29+6 weeks of gestational age (GA) were enrolled. Histological characteristics of placentas from their mothers were classified as normal (CTRL group), histological CA (HCA) and vascular underperfusion (VU). Serum concentrations of isoprostanes (IsoPs), non-protein bound iron (NPBI) and advanced oxidative protein products (AOPP), were determined in cord blood. RESULTS: IsoPs, NPBI and AOPP were significantly increased in HCA group compared to CTRL group. The multivariable regression model, adjusted for GA, maternal age, parity, maternal diabetes, maternal obesity and presence/absence of fetal growth restriction (FGR), showed a significant association between the presence of HCA and increased OS biomarkers levels in cord blood (IsoPs: p = 0.006; NPBI: p = 0.014; AOPP: p = 0.007). Placental VU lesions were significantly associated with higher umbilical IsoPs, NPBI and AOPP levels (IsoPs: p = 0.008; NPBI: p = 0.002; AOPP: p = 0.040). In the cases of placental VU lesions associations were also found between high AOPP levels and low GA (p = 0.002) and the presence of fetal growth restriction (p = 0.014). CONCLUSIONS: Placental lesions indicating inflammation or impaired perfusion are associated with higher cord blood levels of OS biomarkers explaining the fetal susceptibility to oxidative injury and the need of antioxidant protection. PMID- 27697225 TI - Placental vascularity and markers of angiogenesis in relation to prenatal growth status in overnourished adolescent ewes. AB - INTRODUCTION: Placental vascularity may be important in the development of fetal growth restriction (FGR). The overnourished adolescent ewe is a robust model of the condition, with ~50% of offspring demonstrating FGR (birthweight >2 standard deviations below optimally-fed control mean). We studied whether placental vascularity, angiogenesis and glucose transport reflect FGR severity. METHODS: Singleton pregnancies were established in adolescent ewes either overnourished to putatively restrict fetoplacental growth (n = 27) or control-fed (n = 12). At 131d (term = 145d) pregnancies were interrupted and fetuses classified as FGR (n = 17, <4222 g, -2SD below control-fed mean) or non-FGR (n = 10). Placentome capillary area density (CAD), number density (CND), surface density (CSD), and area per capillary (APC) in the fetal cotyledon (COT) and maternal caruncle (CAR) were analysed using immunostaining. COT/CAR mRNA expression of angiogenic ligands/receptors and glucose transporters were measured by qRT-PCR. RESULTS: Fetal weight was reduced in FGR vs. Non-FGR/Control groups. Total placentome weight was Control > Non-FGR > FGR and fetal:placental weight ratios were higher in overnourished versus Control groups. COT vascular indices were Non-FGR > FGR > Control. COT-CAD, CSD and APC were significantly greater in Non-FGR overnourished versus Control and intermediate in FGR groups. CAR vascularity did not differ. CAR-VEGFA/FLT1/KDR/ANGPT1/ANGPT2/SLC2A1/SLC2A3 mRNA was lower and COT-ANGPT2 higher in overnourished versus Control groups. DISCUSSION: Relative to control intake pregnancy, overnourished pregnancies are characterised by higher COT vascularity, potentially a compensatory response to reduced nutrient supply, reflected by higher fetal:placental weight ratios. Compared with overnourished pregnancies where fetal growth is relatively preserved, overnourished pregnancies culminating in marked FGR have less placental vascularity, suggesting incomplete adaptation to the prenatal insult. PMID- 27697226 TI - Alcohol exposure impairs trophoblast survival and alters subtype-specific gene expression in vitro. AB - Maternal alcohol consumption is common prior to pregnancy recognition and in the rat results in altered placental development and fetal growth restriction. To assess the effect of ethanol (EtOH) exposure on the differentiation of trophoblast stem (TS) cells, mouse TS lines were differentiated in vitro for 6 days in 0%, 0.2% or 1% EtOH. This reduced both trophoblast survival and expression of labyrinth and junctional zone trophoblast subtype-specific genes. This suggests that fetal growth restriction and altered placental development associated with maternal alcohol consumption in the periconceptional period could be mediated in part by direct effects on trophoblast development. PMID- 27697227 TI - DNA methylation-associated repression of MEST/PEG1 expression contributes to the invasion of extravillous trophoblast cells. AB - INTRODUCTION: The invasion of extravillous cytotrophoblasts (EVTs) into the maternal uterine decidua and vasculature is critical for human placenta development and pregnancy maintenance. The imprinted gene MEST/PEG1 has been implicated in trophoblast development; however, the role of MEST in EVT invasion and the accompanying early pregnancy complications are not fully understood. METHODS: Western blot, immunofluorescence and immunohistochemistry were used to detect MEST protein expression and localization by using antibodies recognize 2 reported isoforms. Specific small interference RNA (siRNA) targeting both of the MEST isoforms was applied to silence MEST expression in extravillous explants and HTR8/SVneo cells. Cell invasion and migration were assessed using the Matrigel invasion, Transwell migration assay and the xCELLigence system. Promoter DNA methylation was examined using bisulfite-sequencing polymerase chain reaction (BSP). RESULTS: MEST protein was highly expressed in EVTs in the first trimester placenta and in the invasive EVT cell lines HTR-8/Svneo and HPT-8. Weak MEST expression was found in cytotrophoblasts (CTBs) and the choriocarcinoma-derived CTB cell line JEG-3. The specific siRNA knockdown of MEST expression significantly reduced HTR-8/Svneo cell invasion and migration as well as extravillous explant outgrowth, which were associated with the downregulation of Twist, N-cadherin and Vimentin. Decreased MEST protein expression with isoform 2 promoter hypermethylation was observed in the placentas of missed abortions, suggesting a possible pathological mechanism of missed abortion. CONCLUSIONS: Suppressed expression of MEST was associated with its isoform 2 promoter hypermethylation ex vivo placenta tissues and in vitro cultured EVT cell lines. The present results provide a possible pathological mechanism of missed abortion. PMID- 27697229 TI - Hospital information system institutionalization processes in indonesian public, government-owned and privately owned hospitals. AB - The Hospital Information System (HIS) could help hospitals as a public entity to provide optimal health services. One of the main challenges of HIS implementation is an institutional change. Using institutional theory as the analytical lens, this study aims to explain the institutionalization of HIS as an instance of e health initiatives in Indonesia. Furthermore, this paper aims for hospital management and researchers to improve the understanding of the social forces that influence hospital personnel's HIS acceptance within an organizational context. We use case studies from four public, government-owned hospitals and four privately owned (public and specialty) hospitals to explain the HIS institutionalization process by exploring the three concepts of institutional theory: institutional isomorphism, institutional logic, and institutional entrepreneurship. This study reveals that differences exist between public, government-owned and private hospitals with regard to the institutionalization process: public, government-owned hospitals' management is more motivated to implement HIS to comply with the regulations, while private hospitals' management views HIS as an urgent requirement that must be achieved. The study findings also reveal that various institutional isomorphism mechanisms and forms of institutional logic emerge during the process. Finally, three factors-self efficacy, social influence, and management support-have a significant influence on the individual acceptance of HIS. PMID- 27697228 TI - Capturing the patients' voices: Planning for patient-centered electronic health record use. AB - OBJECTIVES: To understand (1) the perceptions of patients regarding use of EHR during clinic visits, (2) the impact of the presence of EHR on patient interactions with physicians, and (3) the ways in which EHR usage might increase patient engagement. METHODS: We conducted semi-structured interviews of a convenience sample of patients of internal medicine resident doctors from three primary care clinics. Interviews were audio-recorded and transcribed verbatim. We used thematic analysis to identify themes from the transcripts. Informed consent was obtained from each participant. RESULTS: We interviewed 32 patients; 37.5% male. Our analysis revealed three primary themes: (1) the views and beliefs of patients on the use of EHR in clinics, (2) patients' perception of the communication skills of residents, and (3) patients' perceptions about information sharing, patient engagement, and health education related to the EHR. An invitation to patients to view the screen as the physician interprets its content increases patient satisfaction and understanding. Residents' possessed skills in communication is not impeded when using EHR. CONCLUSION: Patients generally express a positive or neutral perception of EHR use during clinic visits. Using information voiced by patients, we can teach health providers EHR strategies that are likely to engage patients in the visit and engender their trust. PMID- 27697230 TI - Inpatient satisfaction and usage patterns of personalized smart bedside station system for patient-centered service at a tertiary university hospital. AB - OBJECTIVE: Bedside stations, also known as bedside terminals, are in place to enhance the quality and experience of a hospital's healthcare service delivery. The purpose of this study was to identify information needs and overall satisfaction with the personalized patient bedside system, called Smart Bedside Station (SBS) system, embedded in a tertiary general university hospital. METHODS: End-user responses on the satisfaction survey and system usage logs of the SBS system were collected and analyzed. For the user opinion survey, 156 nurses and 1914 patients, their family members, or caregivers participated during the evaluation period of 2013 to 2014 in this study. All working nurses in the SBS-installed ward were answered the paper-based evaluation, for complete enumeration survey. Inpatients were voluntary participated to deliver the online questionnaire on the SBS menu. We also explored system log data including page calls and usage time from December 2013 to 2015. RESULTS: Regarding the relationship of overall satisfaction of the SBS with patient's characteristics, patient's education status and degree of familiarity with the smart device were statistically significant. From the analysis of system logs, Personalized My Menu(28.0%) was the most frequently used menu item (except for TV and Internet entertainment service use of 62.7%),it provides individual health information, such as laboratory test results, hospital fee check, message logs, daily medication information, and meal information. Next frequently used menus were information support(4.9%) which deliver hospital guide and health information and convenience service ordering(4.4%) such as meal order, bed sheet change. Satisfaction survey results and log data results show that the personalized service enhances the user satisfaction during hospital admission. CONCLUSIONS: Our post-implementation experience and subsequent assessment of SBS system is capable of providing insights into improving the hospital information system and service contents for patient-centered services. Further research should be directed at developing sophisticated patient-centered services as a communication tool between the hospital and the patient. PMID- 27697231 TI - MiBAlert-a new information tool to fight multidrug-resistant bacteria in the hospital setting. AB - BACKGROUND: Although the timely isolation of patients is an essential intervention to limit spread of drug-resistant bacteria, information about the colonization status is often unavailable or lost when patients are readmitted or transferred between hospitals. Therefore, carriers of drug resistant bacteria are not recognized sufficiently early, and proper and timely isolation precautions are not taken. Consequently, resistant bacteria of public health concerns including vancomycin resistant enterococci (VRE) and methicillin resistant Staphylococcus aureus (MRSA) can spread epidemically. To ensure timely identification and proper isolation of such patients we developed an automatic real-time alert of carriers of drug resistant bacteria. OBJECTIVES: The aim of this paper is to describe the system, called MiBAlert, and share the initial experiences in connection with an outbreak of VRE in the greater Copenhagen area (the Capital region), Denmark. METHODS: We obtained data on cases of VRE from hospitals in Copenhagen during the period when the first version of MiBAlert was implemented and log-data on the use of MiBAlert. Furthermore, a survey was conducted among 88 staff members to investigate their experiences of MiBAlert. RESULTS: The alert is a tool directed toward healthcare personnel accessing the electronic health record (EHR) and those further involved in the care and treatment of the patient. It is based on a web service using data from the national microbiological database, MiBa. MiBAlert is a real-time electronic non intrusive alert generated automatically in the header of the EHR each time record is accessed. On February 15, 2015 a pilot version of MiBAlert was launched. All positive tests for VRE throughout 1year were shown with alert status by MiBAlert visible to all medical staff with access to EHR. The alert system was automatically updated directly in the EHR across the five hospitals in the Capital region. We found that the system performed satisfactorily, being operational 24/7 all 135 trial days, apart from 72min, for all the hospitals. Of the staff who responded to the survey, 82% considered that MiBAlert overall improved compliance with isolation precautions regarding VRE-positive patients. We found a marked decline of new patients infected or colonized with VRE concomitant with the implementation of MiBAlert and the survey results. CONCLUSION: We found that MiBAlert was a valuable tool in a bundle approach to counter a multiple hospital outbreak of VRE, and that it has a great potential to improve the control of other drug-resistant bacteria. PMID- 27697232 TI - The development and use of a new methodology to reconstruct courses of admission and ambulatory care based on the Danish National Patient Registry. AB - INTRODUCTION: The Danish National Patient Registry (DNPR) contains clinical and administrative data on all patients treated in Danish hospitals. The data model used for reporting is based on standardized coding of contacts rather than courses of admissions and ambulatory care. METHODS: To reconstruct a coherent picture of courses of admission and ambulatory care, we designed an algorithm with 28 rules that manages transfers between departments, between hospitals and inconsistencies in the data, e.g., missing time stamps, overlaps and gaps. We used data from patients admitted between 1 January 2010 and 31 December 2014. RESULTS: After application of the DNPR algorithm, we estimated an average of 1,149,616 courses of admission per year or 205 hospitalizations per 1000 inhabitants per year. The median length of stay decreased from 1.58days in 2010 to 1.29days in 2014. The number of transfers between departments within a hospital increased from 111,576 to 176,134 while the number of transfers between hospitals decreased from 68,522 to 61,203. CONCLUSIONS: We standardized a 28-rule algorithm to relate registrations in the DNPR to each other in a coherent way. With the algorithm, we estimated 1.15 million courses of admissions per year, which probably reflects a more accurate estimate than the estimates that have been published previously. Courses of admission became shorter between 2010 and 2014 and outpatient contacts longer. These figures are compatible with a cost conscious secondary healthcare system undertaking specialized treatment within a hospital and limiting referral to advanced services at other hospitals. PMID- 27697234 TI - Sociotechnical analysis of nurses' use of personal mobile phones at work. AB - BACKGROUND: Nurses' use of personal mobiles phones at work is a growing trend in healthcare organizations. Although recent studies have explored the positive and negative implications of nurses using personal mobile phones at work, none has yet analyzed the interactions of sociotechnical components (users, technology and policy) on nurses' use of personal mobile phones at work. OBJECTIVES: Identify sociotechnical interactions by analyzing each sociotechnical component (users, technology and policy) that affects nurses' use of personal mobile phones at work. METHODS: In-depth interviews were conducted with 30 nurses employed in 13 hospitals in the Philippines. The respondents include staff nurses (n=23), charge nurses (n=4), and nurse managers (n=3). Staff nurses were asked on their use of personal mobile phones at work, while charge and nurse managers were asked on their observations regarding staff nurses' use of personal mobile phones at work. Responses were analyzed qualitatively using sociotechnical analysis. RESULTS: Sociotechnical analysis indicated that staff nurses used their personal mobile phones at work in various ways because its use helped in their nursing work, but inevitably altered a few of their routines. Although most hospitals had policies that prohibit the use of mobile phones, staff nurses justified their use of personal mobile phones by using it for work purposes and for the benefit of their patients. Staff nurses highlighted the absence of hospital-provided mobile phones as a key reason for using personal mobile phones at work. Charge nurses and nurse managers also influenced staff nurses' use of personal mobile phones at work. CONCLUSIONS: Nurses could use their personal mobile phones at work for work purposes to enhance their clinical performance and improve patient care. Hospital administrators can leverage on nurses' use of personal mobile phones at work by formulating policies that consider both the benefits and potential drawbacks of mobile phone usage. Recommendations are made for the formulation of hospital policies to optimize the use of personal mobile phones of nurses at work. PMID- 27697233 TI - Assessing the quality of routine data for the prevention of mother-to-child transmission of HIV: An analytical observational study in two health districts with high HIV prevalence in South Africa. AB - BACKGROUND: The prevention of mother-to-child transmission of HIV (PMTCT) is a key maternal and child-health intervention in the context of the HIV/AIDS pandemic in South Africa. Accordingly, the PMTCT programmes have been incorporated in the routine District Health Management Information System (DHMIS) which collects monthly facility-based data to support the management of public health services. To date, there has been no comprehensive evaluation of the PMTCT information system. OBJECTIVES: This study seeks to evaluate the quality of output indicators for monitoring PMTCT interventions in two health districts with high HIV prevalence. METHODS: An analytical observational study was undertaken based on the Performance of Routine Information System Management (PRISM) framework and tools, including an assessment of the routine PMTCT data for quality in terms of accuracy and completeness. Data were collected from 57 public health facilities for six pre-defined PMTCT data elements by comparing the source registers with the routine monthly report (RMR), and the RMR with the DMHIS for January and April 2012. This was supplemented by the analysis of the monthly data reported routinely in the DMHIS for the period 2009-2012. Descriptive statistics, analysis of variance (ANOVA) and Bland Altman analysis were conducted using STATA(r) Version 13. RESULTS: Although completeness was relatively high at 91% (95% CI: 78-100%) at facility level and 96% (95% CI: 92-100%) at district level, the study revealed considerable data quality concerns for the PMTCT information with an average accuracy between the register and RMR of 51% (95% CI: 44-58%) and between the RMR and DHMIS database of 84% (95% CI: 78-91%). We observed differences in the data accuracy by organisational authority. The poor quality of the data was attributed partly to insufficient competencies of health information personnel. CONCLUSIONS: The study suggests that the primary point of departure for accurate data transfer is during the collation process. Institutional capacity to improve data quality at the facility level and ensure core competencies for routine health information system (RHIS)-related tasks are needed. Further exploration of the possible factors that may influence data accuracy, such as supervision, RHIS processes, training and leadership are needed. In particular understanding is needed about how individual actions can bring about changes in institutional routines. PMID- 27697235 TI - Information needs of Botswana health care workers and perceptions of wikipedia. AB - BACKGROUND: Since the UN Human Rights Council's recognition on the subject in 2011, the right to access the Internet and information is now considered one of the most basic human rights of global citizens [1,2]. Despite this, an information gap between developed and resource-limited countries remains, and there is scant research on actual information needs of workers themselves. The Republic of Botswana represents a fertile ground to address existing gaps in research, policy, and practice, due to its demonstrated gap in access to information and specialists among rural health care workers (HCWs), burgeoning mHealth capacity, and a timely offer from Orange Telecommunications to access Wikipedia for free on mobile platforms for Botswana subscribers. OBJECTIVES: In this study, we sought to identify clinical information needs of HCWs of Botswana and their perception of Wikipedia as a clinical tool. METHODS: Twenty-eight facilitated focus groups, consisting of 113 HCWs of various cadres based at district hospitals, clinics, and health posts around Botswana, were employed. Transcription and thematic analysis were performed for those groups. RESULTS: Access to the Internet is limited at most facilities. Most HCWs placed high importance upon using Botswana Ministry of Health (MoH) resources for obtaining credible clinical information. However, the clinical applicability of these materials was limited due to discrepancies amongst sources, potentially outdated information, and poor optimization for time-sensitive circumstances. As a result, HCWs faced challenges, such as loss of patient trust and compromises in patient care. Potential solutions posed by HCWs to address these issues included: multifaceted improvements in Internet infrastructure, access to up-to-date information, transfer of knowledge from MoH to HCW, and improving content and applicability of currently available information. Topics of clinical information needs were broad and encompassed: HIV, TB (Tuberculosis), OB/GYN (Obstetrics and Gynecology), and Pediatrics. HCW attitudes towards Wikipedia were variable; some trusted Wikipedia as a reliable point of care information resource whereas others thought that its use should be restricted and monitored by the MoH. CONCLUSIONS: There is a demonstrated need for accessible, reliable, and up-to-date information to aid clinical practice in Botswana. Attitudes towards Wikipedia as an open information resource tool are at best, split. Therefore, future studies are necessary to determine the accuracy, currency, and relevancy of Wikipedia articles on the health topics identified by health care workers as areas of information need. More broadly speaking, future efforts should be dedicated to configure a quality-controlled, readily accessible mobile platform based clinical information application tool fitting for Botswana. PMID- 27697236 TI - Introduction. PMID- 27697237 TI - Determination of death: Metaphysical and biomedical discourse. AB - The prominence of biomedical criteria relying on brain death reduces the impact of metaphysical, anthropological, psychosocial, cultural, religious, and legal aspects disclosing the real value and essence of human life. The aim of this literature review is to discuss metaphysical and biomedical approaches toward death and their complimentary relationship in the determination of death. A critical appraisal of theoretical and scientific evidence and legal documents supported analytical discourse. In the metaphysical discourse of death, two main questions about what human death is and how to determine the fact of death clearly separate the ontological and epistemological aspects of death. During the 20th century, various understandings of human death distinguished two different approaches toward the human: the human is a subject of activities or a subject of the human being. Extinction of the difference between the entities and the being, emphasized as rational-logical instrumentation, is not sufficient to understand death thoroughly. Biological criteria of death are associated with biological features and irreversible loss of certain cognitive capabilities. Debating on the question "Does a brain death mean death of a human being?" two approaches are considering: the body-centrist and the mind-centrist. By bridging those two alternatives human death appears not only as biomedical, but also as metaphysical phenomenon. It was summarized that a predominance of clinical criteria for determination of death in practice leads to medicalization of death and limits the holistic perspective toward individual's death. Therefore, the balance of metaphysical and biomedical approaches toward death and its determination would decrease the medicalization of the concept of death. PMID- 27697238 TI - The acute effects of passive heat exposure on arterial stiffness, oxidative stress, and inflammation. AB - BACKGROUND AND OBJECTIVE: The aim of the study was to determine the acute effect of passive heat exposure (PHE) on arterial stiffness, oxidative stress (OxS) and inflammatory parameters. MATERIALS AND METHODS: Subjects were studied in thermoneutral conditions before and after PHE in a climatic chamber. Pulse wave analysis was used for assessment of central hemodynamic and arterial stiffness parameters. Venous blood samples were obtained to measure OxS and inflammatory parameters. RESULTS: Rectal temperature increased after PHE exposure compared to baseline: 37.01 degrees C+/-0.19 degrees C and 36.4 degrees C+/-0.31 degrees C, respectively (P<0.001). There was a 17% (P<0.05) decrease in large artery elasticity index (from 24.68+/-5.53 to 20.42+/-2.65mL/mmHg*10), which was predicted upon normothermic value (r=-0.878, P<0.01). However, no significant changes were found in others arterial stiffness parameters. A 30% (P<0.05) increase occurred in blood IL-6 concentration (from 0.43+/-0.15 to 0.56+/ 0.23pg/mL), but OxS parameters remained significantly unchanged. CONCLUSIONS: This study describes for the first time acute PHE effects on arterial stiffness, inflammation and OxS. PHE significantly decreases large artery elasticity index and increases inflammatory IL-6 level. However, further larger investigations are needed for clarifying acute PHE effects on arterial function and biomarkers.

PMID- 27697239 TI - Health care professionals' skills regarding patient safety. AB - BACKGROUND AND OBJECTIVE: The importance of patient safety is growing worldwide, and every day, health care professionals face various challenges in how to provide safe care for their patients. Patient safety skills are one of the main tools to ensure safe practice. This study looks to describe health care professionals' skills regarding patient safety. MATERIALS AND METHODS: Data were collected using the skill scale of the Patient Safety Attitudes, Skills and Knowledge (PS-ASK) instrument from different health care professionals (n=1082: physicians, head nurses, nurses and nurse assistants) working in hospitals for adult patients in three regional multi-profile hospitals in the western part of Lithuania. RESULTS: Overall, the results of this study show that based on their own evaluations, health care professionals were competent regarding their safety skills. In particular, they were competent in the sub-scale areas of error analysis (mean=3.09) and in avoiding threats to patient safety (mean=3.31), but only somewhat competent in using decision support technology (mean=2.00). Demographic and other work related background factors were only slightly associated with these patient safety skills areas. Especially, it was noted that nurse assistants may need more support from managers and colleagues in developing their patient safety skills competence. CONCLUSIONS: This study has served to investigate the general skills of health care professionals in regard to patient safety. It provides new knowledge about the topic in the context of the Baltic countries and can thus be used in the future development of health care services. PMID- 27697241 TI - White ring sign for uneventful lenticule separation in small-incision lenticule extraction. AB - : We describe the white ring sign, which differentiates the posterior and anterior lenticular planes in small-incision lenticule extraction. The sign identifies the plane of dissection by the anteroposterior relationship between the dissecting instrument and the circular white light reflected from the lenticular side cut. Differentiating the planes enables the surgeon to dissect the anterior plane before the posterior plane, which facilitates smooth lenticule extraction and prevents complications such as cap tears, partial lenticule dissection, and a torn lenticule.

PMID- 27697242 TI - Treating capsule contraction syndrome with a femtosecond laser. AB - : We describe a technique that uses a femtosecond laser (femtosecond laser pseudophakic capsulotomy) to treat capsule contraction syndrome (capsule phimosis) that may occur after cataract surgery and intraocular lens (IOL) implantation. Enlarging the capsulotomy with a femtosecond laser may offer advantages over the existing treatment methods, neodymium:YAG laser capsulotomy and manual extension of the capsulorhexis.

PMID- 27697243 TI - Intraocular lens exchange surgery at a tertiary referral center: Indications, complications, and visual outcomes. AB - PURPOSE: To identify indications for and visual outcomes of intraocular lens (IOL) exchange to understand recent changes in this surgery. SETTING: Academic tertiary referral center. DESIGN: Retrospective case series. METHODS: Cases were identified by searching the institution's electronic medical records from January 2010 to September 2015 for patients treated by 1 staff physician with the American Medical Association's Current Procedural Terminology code for IOL exchange. These cases were reviewed to determine the surgical indication, type of IOL removed, type of IOL implanted, time between surgeries, surgical complications, and visual outcomes. RESULTS: The study comprised medical records of 109 eyes. The mean time between the primary cataract surgery and IOL exchange was 1657 days. Dislocation of an in-the-bag posterior chamber IOL (27.5%), intolerance of a multifocal IOL (18.3%), and uveitis-glaucoma-hyphema syndrome (11.9%) were the most frequent indications for IOL exchange. The final IOL position after exchange was most frequently in the capsular bag (43.1%), anterior chamber (25.7%), or sulcus (22%). The final visual acuity at 1 month was 20/40 or better in 78.9% of cases. Of those not achieving this level of acuity, pathology not related to exchange surgery was identified in 48% of cases. The most frequent complications after IOL exchange surgery were posterior capsule opacification (13.8%), cystoid macular edema (10.1%), and high astigmatism (>1.5 diopters) (8.3%). CONCLUSIONS: The most frequent indication for IOL exchange surgery was dislocated IOLs; the second most frequent indication was patient dissatisfaction after multifocal IOL implantation. The increased ability to place an intracapsular IOL with few intraoperative complications and largely treatable postoperative complications enhances the effectiveness of IOL exchange surgery and patient satisfaction.

PMID- 27697244 TI - Clinical outcomes of a new extended range of vision intraocular lens: International Multicenter Concerto Study. AB - PURPOSE: To analyze the clinical outcomes after implantation of an extended range of vision intraocular lens (IOL), the Tecnis Symfony, in a routine clinical setting. SETTING: Forty clinical sites in Finland, France, Germany, Norway, Spain, Sweden, and the United Kingdom. DESIGN: Prospective case series. METHODS: The study comprised 411 patients who had bilateral implantation of the extended range of vision IOL, with intended micro-monovision in 1 group (monovision group) and intended emmetropia in the other group (non-monovision group). Visual acuity, spectacle independence, patient and surgeon satisfaction, and photic phenomena were analyzed during the 4- to 6-month follow-up. RESULTS: The monovision group comprised 112 patients and the non-monovision group, 299 patients. The mean decimal uncorrected distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuities were 0.95, 0.81, and 0.69, respectively, 4 to 6 months postoperatively. Significantly better UIVA (P = .003) and UNVA (P = .011) were found in the monovision group than in the non-monovision group. Spectacle independence was high, with 14.4% of eyes requiring reading spectacles frequently. More than 90% of patients reported no or mild halos, glare, starbursts, or other photic phenomena. Patient satisfaction scores (median) for distance, intermediate, and near vision were 9.0, 10.0, and 8.0, respectively. The satisfaction score for near vision increased to 9.0 in the monovision group. More than 91% of patients said they would recommend the same procedure to their friends and family. CONCLUSION: The extended range of vision IOL provided successful visual restoration across all distances after cataract surgery, with a minimal level of disturbing photic phenomena and high levels of patient satisfaction.

PMID- 27697245 TI - Differences in visual quality with orientation of a rotationally asymmetric bifocal intraocular lens design. AB - PURPOSE: To evaluate visual and perceptual performance for different orientations of a rotationally asymmetric bifocal intraocular lens (IOL) (M-Plus) simulated optically using a simultaneous vision simulator. SETTING: Instituto de Optica, Madrid, Spain. DESIGN: Prospective observational study. METHODS: Perceptual quality and decimal high-contrast visual acuity (HCVA) was measured under cycloplegia for 8 orientations of the asymmetric bifocal IOL phase pattern at far, intermediate, and near distances simulated with a simultaneous vision simulator using face images and tumbling E targets. The preferred orientation at each distance was calculated as the centroid of the data for 8 orientations. The visual Strehl value was calculated using the subjects' ocular aberrations and multifocal pattern at each orientation. Optical predictions were obtained by implementing a differential visual Strehl values-based ideal observer model. RESULTS: The study comprised 20 subjects (aged 21 to 62 years). Horizontal orientation (near segment at 0 or 180 degrees +/- 45 [SD]) was preferred by 14 subjects and by 13 subjects at far and near distances, respectively; 8 subjects showed strong orientation preferences. The mean difference in preferred orientation between far and near was 27 +/- 22 degrees. No significant differences in HCVA were observed. Optical predictions correlated strongly and significantly with measurements (far r = 0.71, near r = 0.62; P < .0001). The mean difference between measurement and simulation in the preferred orientation was 28 +/- 29 degrees at far and 36 +/- 28 degrees at near. CONCLUSIONS: The perception varied for different orientations of an asymmetric bifocal IOL design tested using a simultaneous vision simulator. Optimum orientation was driven by interactions of the design with the eye's optical aberrations.

PMID- 27697246 TI - Expanding binocular depth of focus by combining monovision with diffractive bifocal intraocular lenses. AB - PURPOSE: To test the hypothesis that binocular depth of field can be expanded while retaining high-quality vision at intermediate distances by combining anisometropia (monovision) and simultaneous vision bifocals. SETTING: School of Optometry, Indiana University, Bloomington, Indiana, USA. DESIGN: Prospective research study. METHODS: A computational polychromatic model was used to simulate retinal images as seen through a pseudophakic eye with a diffractive bifocal for a range of target distances. Computationally blurred stimuli were presented dichoptically, simulating a binocular pseudophakic person with 1 emmetropic eye and 1 eye with myopia of 0.40 diopter (D), 0.80 D, or 1.20 D. Binocular visual acuity was measured for computationally blurred high-contrast Sloan letters. RESULTS: Ten subjects participated in this study. The emmetropic eye achieved best vision at infinity and near distance specified by the addition (add) power, while the myopic eye peak acuities were achieved at shorter viewing distances. Having 1 myopic bifocal eye had no effect on distance acuities. With a bifocal add of 2.20 D and 1.20 D of anisometropia, the binocular depth of focus was more than 3.00 D and provided binocular acuities of better than 20/20 throughout this range. For each target distance, the binocular acuities closely approached those of the better-focused eye. CONCLUSIONS: By careful selection of unilateral myopia and bilateral use of high-quality bifocal lenses, high intermediate distance acuities can exist with a large depth of field. This approach can improve intermediate vision and expand depth of field without compromising best achievable distance and near acuities.

PMID- 27697247 TI - Effect of cataract surgery training on operating room productivity: How long trainees take. AB - PURPOSE: To determine the effect of specialty training on cataract operation times and operating room efficiency. SETTING: Manchester Royal Eye Hospital, Manchester, United Kingdom. DESIGN: Retrospective consecutive case series. METHODS: Specialty training and consultant case times with preparation times were recorded between August 2014 and May 2015. Cases with posterior capsule rupture requiring anterior vitrectomy or iris hook insertion were analyzed. RESULTS: The study reviewed 1904 cases (906 consultant cases, 797 specialty training cases). Trainees' case time was significantly longer than consultants' (mean 24.25 minutes +/- 12.36 [SD] versus 19.59 +/- 10.05 minutes) (P < .0001). The difference between the 1- to 3-year trainees' mean surgical time and 4- to 7-year trainees' mean surgical time was statistically significant (P < .0001). Mean case time decreased from 27.63 +/- 12.57 minutes (1- to 3-year trainees) to 22.55 +/- 11.90 minutes (4- to 7-year trainees). The mean posterior capsule rupture rate was 2.76% for trainees and 1.77% for consultants. When posterior capsule rupture occurred, the mean surgical time increased to 49.81 +/- 18.69 minutes for the consultant group and 67.00 +/- 26.26 minutes for the trainee group (P = .024). When iris hooks were required, the mean case time was 26.41 +/- 11.28 minutes and 34.11 +/- 15.06 minutes, respectively (P = .026). CONCLUSIONS: Specialty training cases had a longer duration than consultant cases, although the mean surgical time decreased with increased trainee experience. After 3 years of training, trainees did not have a significant effect on operating room efficiency.

PMID- 27697248 TI - Outcomes of topography-guided versus wavefront-optimized laser in situ keratomileusis for myopia in virgin eyes. AB - PURPOSE: To compare the outcomes of topography-guided and wavefront-optimized treatment in patients having laser in situ keratomileusis (LASIK) for myopia. SETTING: Advanced Eye Centre, Post Graduate Institute of Medical Education and Research, Chandigarh, India. DESIGN: Prospective contralateral-eye case study. METHODS: Patients had topography-guided LASIK in 1 eye and wavefront-optimized LASIK in the contralateral eye using the Customized Refractive Surgery Master software and Mel 80 excimer laser. Refractive (residual manifest refraction spherical equivalent [MRSE], higher-order aberrations [HOAs]), and visual (uncorrected distance visual acuity [UDVA] and photopic and mesopic contrast sensitivity) outcomes were prospectively analyzed 6 months postoperatively. RESULTS: The study comprised 35 patients. The UDVA was 0.0 logMAR or better and the postoperative residual MRSE was +/-0.50 diopter in 94.29% of eyes in the topography-guided group and 85.71% of eyes in the wavefront-optimized group (P = .09). More eyes in the topography-guided group than in the wavefront-optimized group had a UDVA of -0.1 logMAR or better (P = .04). Topography-guided LASIK was associated with less deterioration of mesopic contrast sensitivity at higher spatial frequencies (12 cycles per degree [cpd] and 18 cpd) and lower amounts of induced coma (P = .04) and spherical aberration (P = .04). Less stromal tissue was ablated in the topography-guided group (mean 61.57 MUm +/- 16.23 [SD]) than in the wavefront-optimized group (mean 79.71 +/- 14.81 MUm) (P < .001). CONCLUSION: Although topography-guided LASIK and wavefront-optimized LASIK gave excellent results, topography-guided LASIK was associated with better contrast sensitivity, lower induction of HOAs, and a smaller amount of tissue ablation.

PMID- 27697249 TI - Ocular flora and their antibiotic susceptibility in patients having cataract surgery in Italy. AB - PURPOSE: To characterize the ocular flora in a consecutive group of patients having cataract surgery and to determine the antibiotic susceptibility profile of isolates to several ophthalmic antibiotics. SETTING: Hospital Di Stefano, Catania, Italy. DESIGN: Observational case series. METHODS: Conjunctival and eyelid cultures from patients were obtained 14 days before surgery and, if positive, repeated the day of the surgery. Antimicrobial susceptibility for aminoglycosides (netilmicin and tobramycin), fluoroquinolones (ofloxacin, levofloxacin, and moxifloxacin), chloramphenicol, and azithromycin was tested using the Kirby-Bauer disk diffusion method. Susceptibility was also tested for oxacillin, cefuroxime, and vancomycin. All positive patients received a 2-day preoperative course of 3 mg/mL netilmicin ophthalmic solution 4 times a day. The recovery rate of microorganisms after antibiotic treatment compared with baseline was calculated. RESULTS: One hundred twenty consecutive patients were included in the study. Cultures were positive in 72.5% of patients; 131 isolates, mainly gram positive, were identified. Staphylococcus epidermidis (58.0%) and Staphylococcus aureus (15.3%) were the most frequently isolated microorganisms. Methicillin resistant staphylococci accounted for 3.8% of S epidermidis and 20.0% of S aureus. A high in vitro susceptibility (>90%) for all isolates, including multiresistant coagulase-negative Staphylococcus, was obtained for netilmicin, vancomycin, and cefuroxime. The recovery rate of isolates before surgery was reduced by 93.9% (P < .001). CONCLUSIONS: Conjunctival and lid margin isolates were sensitive to netilmicin, vancomycin, and cefuroxime. Microorganisms were less susceptible to other ophthalmic antibiotics, with the exception of moxifloxacin. A 2-day preoperative course with topical netilmicin reduced most bacteria identified on the conjunctiva and eyelids.

PMID- 27697250 TI - Endophthalmitis after cataract surgery despite intracameral antibiotic prophylaxis with licensed cefuroxime. AB - PURPOSE: To report a case series of post-phacoemulsification endophthalmitis despite antibiotic prophylaxis with an intracameral injection of a licensed cefuroxime formulation (Aprokam). SETTING: University Hospitals of Pointe-a Pitre, Guadeloupe, and Fort-de-France, Martinique, French West Indies. DESIGN: Retrospective case series. METHODS: Patients who had cataract surgery with licensed cefuroxime prophylaxis between March 1, 2013, and July 31, 2015, and developed endophthalmitis were included. Bacteriologic findings and final corrected distance visual acuity 6 months after treatment were collected. RESULTS: Five patients developed endophthalmitis within 15 days after surgery, which was performed in different settings by different cataract surgeons. All patients had no-stich cataract surgery. Surgery was uneventful in 4 cases. One patient had a posterior capsule rupture. An anterior chamber paracentesis with analysis of the aqueous humor was performed to confirm endophthalmitis. Bacteriologic tests showed alpha-hemolytic streptococcus in 2 cases, Staphylococcus epidermidis in 1 case, and Serratia marcescens in 1 case. Two strains of bacteria showed cefuroxime resistance on the antibiogram. Despite parenteral and intravitreal injections of antibiotics, 4 of 5 cases had a poor outcome, with a visual acuity of less than 20/200. Retinal detachment (RD) was the most frequent complication observed in the following months. CONCLUSIONS: Although licensed cefuroxime has proven to be efficient in reducing the incidence of endophthalmitis, it has not eradicated this potentially severe complication of cataract surgery. Endophthalmitis occurring after the use of licensed cefuroxime can still result in very poor visual outcomes related to the infection itself or to its delayed complications such as RD.

PMID- 27697251 TI - Late postoperative opacification of a hydrophilic-hydrophobic acrylic intraocular lens. AB - PURPOSE: To report late postoperative opacification of a model of hydrophilic hydrophobic acrylic intraocular lens (IOL) as well as the clinical consequences and laboratory characteristics. SETTING: Department of Ophthalmology, Centro Hospitalar e Universitario de Coimbra, Coimbra, Portugal. DESIGN: Retrospective case series. METHODS: Medical records were reviewed of patients with Lentis LS 502-1 IOL opacification reporting visual loss who had IOL explantation between November 2013 and March 2015. Patients were identified in the emergency room or during regular follow-up visits. Explanted IOLs were analyzed at the Ophthalmic Explants Biobank, Vissum, Spain, or at the John A. Moran Eye Center, University of Utah, USA. RESULTS: Twenty opacified IOLs were explanted from 19 patients. The mean interval between cataract surgery and diagnosis of opacification was 29.15 months +/- 9.57 (SD) (range 6 to 45 months). Opacification led to a statistically significant reduction in corrected distance visual acuity (mean 0.86 +/- 0.76 logMAR; P < .001) and occurred in 5.1% of the hydrophilic-hydrophobic acrylic IOLs implanted at the department. The most frequently associated medical conditions were arterial hypertension, diabetes, and glaucoma. All IOLs but 1 had a similar pattern of opacification, with yellowish diffuse opacification uniformly distributed and calcium deposits on the surface and/or subsurface of the optic and haptics and within the IOL material. CONCLUSIONS: Opacification of the hydrophilic-hydrophobic acrylic IOL was found in a significant number of patients and had a significant effect on their vision. The opacification was attributed to primary calcification. FINANCIAL DISCLOSURE: None of the authors has a financial or proprietary interest in any material or method mentioned. PMID- 27697252 TI - Outcomes after combined phacoemulsification and trabecular microbypass stent implantation in controlled open-angle glaucoma. AB - PURPOSE: To study the effect of combined phacoemulsification cataract surgery and iStent (trabecular microbypass stent) implantation on intraocular pressure (IOP) and medication use in open-angle glaucoma (OAG) patients with a low mean preoperative IOP. SETTING: University of Colorado Health Eye Center, Aurora, Colorado, USA. DESIGN: Retrospective case series. METHODS: Treatment outcomes analyzed included IOP, medication use, and corrected distance visual acuity (CDVA). Treatment success was defined as a 20% or more IOP reduction or discontinuation of at least 1 medication. RESULTS: Sixty-four eyes of 45 patients were included in the analysis. At 1 year, the mean IOP was significantly reduced from 14.7 +/- 3.2 mm Hg (SD) to 13.2 +/- 2.8 mm Hg (P < .01) and the mean medication use decreased from 1.81 +/- 1.13 to 1.41 +/- 1.48 (P = .0001). The estimated IOP reduction at 1, 3, 6, and 12 months was 3.5% (P = .23), 7.9% (P = .04), 9.7% (P = .01), and 12.2% (P = .002), respectively. Treatment success at 1 year was achieved in 76.1% of patients, and 41% of patients were medication free at 1 year. The CDVA was significantly improved from 0.4 +/- 0.38 logMAR at baseline to 0.17 +/- 0.35 at 1 year (P < .0001). CONCLUSIONS: Combined cataract surgery and trabecular microbypass stent implantation was statistically effective in reducing IOP and/or medication burden in OAG patients with a low preoperative IOP. During the informed surgical consent process, the physician and patient should consider the clinical benefit of modest IOP lowering and/or a decrease in medication use. FINANCIAL DISCLOSURE: Drs.

SETTING: Ruhr University Eye Hospital, Bochum, Germany. DESIGN: Prospective interventional case series. METHODS: Eyes having routine femtosecond laser-assisted cataract surgery were included. After wound closure, the anterior eye segment was visualized using the incorporated 3-D SD-OCT. Visualization of Berger space was performed in the axial and sagittal planes. RESULTS: The study comprised 165 consecutive eyes. In 155 eyes, 3-D SD-OCT visualized Berger space and its dimensions were analyzed. In 72% of the cases, Berger space was large enough to perform a femtosecond laser assisted primary posterior capsulotomy. In 24 eyes (15.5%) with a minimum axial length of 25.0 mm, Berger space was 500 MUm or larger. CONCLUSION: Femtosecond laser systems incorporating real-time SD-OCT allowed direct visualization of Berger space intraoperatively, providing surgeons with the information needed to safely create posterior capsulotomies after intraocular lens implantation.

PMID- 27697254 TI - Comparison of different types of phacoemulsification tips. I. Quantitative analysis of elemental composition and tip surface microroughness. AB - PURPOSE: To evaluate the elemental composition of phacoemulsification tips and their surface roughness in the microscale. SETTING: John A. Moran Eye Center and Utah Nanofab, College of Engineering, University of Utah, Salt Lake City, Utah, USA. DESIGN: Experimental study. METHODS: Seven types of phacoemulsification tips were studied. The phaco tips were examined through energy-dispersive x-ray spectroscopy (EDS) and x-ray photoelectron spectroscopy (XPS) for elemental composition. In addition, the roughness of the opening in all tips was assessed through 3-dimensional white-light interferometry. RESULTS: Elemental analysis showed considerable differences in the surface layers between manufacturers. Alcon tips had a thinner oxidized titanium (Ti) layer in their surface. Through XPS, vanadium was not detected in the superficial layers of any tip, but only in deeper levels. The microroughness surface analysis showed comparable results regarding their root-mean-square (RMS) metric. Maximum peak valley distance values varied and appeared to be dependent on the quality of material process rather than the material itself. CONCLUSIONS: Phacoemulsification tips are made of Ti alloys and showed differences between models, especially regarding their composition in the superficial layers. Their opening end roughness showed an overall appropriate RMS value of less than 1.0 MUm in all cases. The existence of small defected areas highlights the importance of adequate quality control of these critical surgical instruments.

II. Morphologic alterations induced by multiple steam sterilization cycles with and without use of enzyme detergents. AB - PURPOSE: To evaluate the alterations in the morphology and elemental composition of reusable phacoemulsification tips after cleaning and sterilization. SETTING: John A. Moran Eye Center, Salt Lake City, Utah, USA. DESIGN: Experimental study. METHODS: For the main experiment, 2 types of reusable phacoemulsification needles were studied. One tip of each type underwent 1, 2, and 3 autoclave sterilizations with the use of detergents followed by thorough rinsing with sterile water between cycles. Another set of tips underwent the same procedure but without rinsing. Subsequently, phaco tips were examined through scanning electron microscopy and energy-dispersive x-ray spectroscopy to assess morphologic changes and surface deposits. In a second experiment, tips of 8 different types (both reusable and single use) underwent 10 sterilization autoclave cycles without detergents. RESULTS: Residues, mostly comprised of carbon-containing material, were found in extensive areas of tips that were sterilization with enzymes and without rinsing. Smaller and fewer residues were found in tips after sterilization with the use of enzymes and thorough rinsing. Tips that underwent autoclave sterilization without detergents had no bulky deposits on their surface; they mostly had thin layers of sodium and chloride or material discoloration. CONCLUSIONS: Rinsing the phaco tips significantly reduced the size and number of residues after use of enzymatic detergents. However, detergent residues were detected on phaco tip surfaces even after thorough rinsing with sterile water. No major noticeable changes were observed in either single-use or reusable phaco tips after 10 cycles of sterilization without detergents.

AB - PURPOSE: To compare the optical performance of 3 trifocal intraocular lenses (IOLs): the Acrysof IQ Panoptix (+2.17 diopter [D]/+3.25 D IOL), AT LISA Tri 839MP (+1.66 D/+3.33 D IOL), and Finevision Micro F (+1.75 D/+3.50 D IOL). SETTING: Alcon Research Ltd., Fort Worth, Texas, USA. DESIGN: Experimental study. METHODS: The 3 trifocal IOLs were compared using optical performance tests. To measure image quality, through-focus modulation transfer function (MTF) curves were generated for a model eye. To assess resolution, through-focus Badal images of an Early Treatment Diabetic Retinopathy Study chart simulating viewing distances of infinity to 40 cm were recorded. To measure photic phenomena, simulated headlight images with a 50 MUm pinhole target and a 5.0 mm pupil were obtained. RESULTS: The MTF measurements showed similar near and distance peaks for the IOLs, but the optimum intermediate peak for the +2.17 D/+3.25 D IOL was 60 cm versus 80 cm for the other 2 trifocal IOLs. Similarly, in bench Badal image testing, the optimum intermediate image was at 60 cm for the +2.17 D/+3.25 D IOL and 80 cm for the other 2 IOLs. Overall, halos surrounding simulated headlight images were equivalent for the 3 IOLs. CONCLUSIONS: In bench studies, the new +2.17 D/+3.25 D trifocal IOL showed equivalent or better performance in image quality, resolution, and photic phenomena compared with the +1.66 D/+3.33 D and +1.75 D/+3.50 D trifocal IOLs. The new IOL is expected to provide better intermediate vision at 60 cm, which is preferred for real-life tasks such as computer work, over the 80 cm intermediate distance offered by the other 2 trifocal IOLs.

AB - : An 85-year-old man developed chronic postoperative endophthalmitis after complicated cataract surgery. Visual acuity in the affected eye was hand movements. Slitlamp biomicroscopy showed a hypopyon, superonasal iris nodule, and marked vitritis. An anterior chamber washout, iris biopsy, and intravitreal amphotericin injection were performed. Panfungal polymerase chain reaction of anterior chamber and vitreous samples were positive for Penicillium citrinum. The iris biopsy showed hyphae on Grocott staining. Despite treatment, the patient's acuity deteriorated to light perception and he developed severe intractable pain requiring evisceration. Histological analysis showed diffuse infiltration of hyphae. Penicillium species are fungal organisms that are ubiquitous in the environment and can cause chronic endophthalmitis. They are commonly dismissed as culture contaminants. True infection is confirmed by histological demonstration of fungal invasion. Diagnosis can be aided by iris biopsy if iris nodules are present. Polymerase chain reaction testing was beneficial in identifying the causative organism and should be considered early in endophthalmitis cases. Despite intravitreal and systemic antifungal treatment, the visual prognosis for this condition is variable.

AB - : Nonsteroidal antiinflammatory drugs (NSAIDs) have become an important adjunctive tool for surgeons performing routine and complicated cataract surgery. These medications have been found to reduce pain, prevent intraoperative miosis, modulate postoperative inflammation, and reduce the incidence of cystoid macular edema (CME). Whether used alone, synergistically with steroids, or for specific high-risk eyes prone to the development of CME, the effectiveness of these medications is compelling. This review describes the potential preoperative, intraoperative, and postoperative uses of NSAIDs, including the potency, indications and treatment paradigms and adverse effects and contraindications. A thorough understanding of these issues will help surgeons maximize the therapeutic benefits of these agents and improve surgical outcomes.

PMID- 27697271 TI - Trajectories and predictors of state and trait anxiety in patients receiving chemotherapy for breast and colorectal cancer: Results from a longitudinal study. AB - PURPOSE: To examine the trajectories and predictors of state and trait anxiety in patients undergoing chemotherapy for breast or colorectal cancer. METHODS: Secondary analysis of data collected as part of a large multi-site longitudinal study. Patients with breast or colorectal cancer completed validated scales assessing their state and trait anxiety levels (State-Trait Anxiety Inventory) and symptom burden (Rotterdam Symptom Checklist) at the beginning of each chemotherapy cycle. Longitudinal mixed model analyses were performed to test changes of trait and state anxiety over time and the predictive value of symptom burden and patients' demographic (age, gender) and clinical characteristics (cancer type, stage, comorbidities, ECOG performance status). RESULTS: Data from 137 patients with breast (60%) or colorectal cancer (40%) were analysed. Linear time effects were found for both state (chi2 = 46.3 [df = 3]; p < 0.001) and trait anxiety (chi2 = 17.708 [df = 3]; p = 0.001), with anxiety levels being higher at baseline and gradually decreasing over the course of chemotherapy. Symptom burden (beta = 0.21; SD = 0.06; p = 0.001) predicted state anxiety throughout treatment, but this effect disappeared when accounting for trait anxiety scores before the start of chemotherapy (beta = 0.85; SD = 0.05; p < 0.001). Patients' baseline trait anxiety was the only significant predictor of anxiety throughout treatment. CONCLUSIONS: Changes in the generally stable characteristic of trait anxiety indicate the profoundly life-altering nature of chemotherapy. The time point before the start of chemotherapy was identified as the most anxiety-provoking, calling for interventions to be delivered as early as possible in the treatment trajectory. Patients with high trait anxiety and symptom burden may benefit from additional support. PMID- 27697272 TI - The influence of symptoms on quality of life among patients who have undergone oesophageal cancer surgery. AB - PURPOSE: After oesophagectomy, anatomical changes and loss of function induce various symptoms that may affect quality of life (QoL) in oesophageal cancer patients. The purpose of this study was to identify the factors influencing QoL in Korean patients who have undergone oesophageal cancer surgery. METHOD: This was a cross-sectional study of a convenience sample consisting of 120 surgery patients with oesophageal cancer. We used the EORTC QLQ-C30 and EORTC QLQ-OES18 to measure participants' oesophageal cancer-related symptoms and QoL. Multiple regression analyses were applied to analyse to the relationship between cancer related symptoms and QoL. RESULTS: The average score of oesophageal cancer related symptoms was 19.28 points, and the most common symptom was reflux. The mean score for global health status/QoL was 60.55. There were significant differences in the functional and symptom subscales according to financial burden, operation type (procedure), and treatment period. Dysphagia most affected global health status/QoL, and eating problems most affected the functional and symptom subscales. CONCLUSION: Dysphagia and eating problems were confirmed to be the most common symptoms affecting the QoL of patients who had undergone oesophageal cancer surgery. These results can be used to aid in the development of strategies to better manage symptoms in these patients.

PMID- 27697274 TI - Disability and quality of life in community-dwelling elderly cancer survivors: Case-control study in the Korean population. AB - PURPOSE: Advanced age is a significant risk factor for cancer and functional disabilities increase with age. The purpose of this case-control study of Korean individuals was to determine the effect of cancer and cancer treatment on functional disability and quality of life (QOL). Thus, we compared community dwelling elderly cancer patients (ECPs) with individuals from the general elderly population (GEP) who never had diagnoses of cancer. METHODS: We selected 1776 ECP who were at least 65 years-old from the 2008 Korean Community Health Survey data and used propensity score matching to randomly select 1766 individuals from the GEP who closely resembled the ECPs. Functional disability was measured using the Instrumental Activities of Daily Living (IADL) scale, and QOL was measured by the EuroQol Group EQ-5D. RESULTS: ECPs were more dependent in preparation of food, doing laundry, and shopping (IADL scale), and in mobility and usual activities (EQ-5D). Although ECP had more problems with pain, discomfort, anxiety, and depression, they were more independent in self-care and handling of financial responsibilities. CONCLUSIONS: ECPs had multiple physical and psychological symptoms that adversely affected functional disability and QOL, but higher functional ability, such as self-care and handling of financial responsibilities. Promotion of self-care by ECPs is pivotal for effective management in community practice. PMID- 27697275 TI - Development of the Head and Neck Cancer Caregiving Task Inventory. AB - PURPOSE: Family caregivers provide vital support for patients with head and neck cancer (HNC), yet few studies have focused on HNC caregiving. Our objective was to develop and conduct initial validation of the HNC Caregiving Task Inventory, an instrument to characterize caregiving task burden in the HNC population. METHODS: This 5-phase instrument development project involved the conceptualization of caregiving task burden (Phase 1), initial instrument development (Phase 2), assessment of content validity through expert panel review (Phase 3), assessment of face validity through family caregiver review (Phase 4), and preliminary validation in a sample of 106 family caregivers (Phase 5). RESULTS: We identified 11 domains of the HNC caregiving role and caregiving tasks for each domain. In Phase 3, the experts deemed all tasks relevant to HNC family caregiving. No tasks were eliminated and 19 were added. In Phase 4, family caregiver feedback indicated that the tasks were comprehensive and relevant. Wording and formatting changes were made and one task was added. In Phase 5, we evaluated discrimination of responses to derive a final version comprised of 58 tasks in 11 domains. Kuder-Richardson values for domains with >=3 items ranged from 0.65 to 0.94. Associations were generally high with the Caregiving Burden Scale, moderate with the Caregiver Reaction Assessment and Profile of Mood States Short Form, and low or non-existent with the Preparedness Scale. CONCLUSION: Convergent and divergent validity were supported. The HNC Caregiving Task Inventory can be used to evaluate caregiving task burden across the treatment trajectory and identify targets for intervention. PMID- 27697276 TI - Understanding the experiences of adolescents and young adults with cancer: A meta synthesis. AB - PURPOSE: To conduct a meta-synthesis of qualitative studies exploring experiences of young cancer patients to identify the overarching concepts that inform future service and research directions. METHOD: A systematic literature search was conducted, and 51 articles published between January 2004 and March 2014 were collected via CINAHL, Medline and PsycINFO databases. Deductive thematic analysis was conducted to identify major themes, guided by Hermeneutic notions on interpretation. RESULTS: Cancer impacted a wide range of life domains. These impacts were interconnected and bi-directional. The meanings of these impacts were closely related to their unique developmental needs and a social position as youth. Emotional struggles during these radical changes were evident, but efforts to make sense of their experiences and find meaning pervaded. CONCLUSIONS: Given the interrelated nature of the cancer challenges young cancer patients experience, there needs to be an emphasis on conducting studies which further refine our understanding of these relationships. This can help to structure effective youth cancer services. Generic informational resources and support services should be tailored so that they have relevance to the young person's life context. The treating team has an important role in fostering young patients' ability to make sense of their experiences by providing developmentally relevant psychosocial support. PMID- 27697277 TI - Existential challenges in young people living with a cancer diagnosis. AB - PURPOSE: In Sweden, approximately 500 people between the ages of 15 and 39 are diagnosed with cancer each year. When someone is diagnosed with a life threatening disease, existential issues are easily triggered. Young adults are in a developmental phase of life and are exposed to an extra amount of pressure. The Internet and social media are a daily part of the life of young adults and the use of blogs is common. The aim of this study was to elucidate the theoretical framework of Yalom and his four 'givens' expressed in blogs written by young adults living with various cancer diagnoses in Sweden. METHOD: This study used a qualitative method in which written stories from six public blogs were analysed using qualitative content analysis. RESULTS: The findings offer valuable in-depth knowledge about the existential issues in this population. The results can be described as a journey with several existential challenges and with death as an impending threat. The bloggers' awareness of their mortality was described as creating a sense of loss and existential loneliness. CONCLUSIONS: This study shows that young adults are empowered by the writing of blogs and that blogs can play an important part in increasing wellbeing and a sense of coherence within this population. PMID- 27697278 TI - Addressing behavioral impacts of childhood leukemia: A feasibility pilot randomized controlled trial of a group videoconferencing parenting intervention. AB - PURPOSE: Child emotional and behavioral problems constitute significant sequelae of acute lymphoblastic leukemia (ALL) treatment. The aims of this study were to a) examine the feasibility, acceptability and satisfaction of a parenting intervention amongst parents of children with ALL and b) explore whether participation in a parenting intervention shows promise for improvements in child behavior. METHODS: 12 parents with a child aged between 2 and 8 years receiving maintenance phase treatment for ALL participated in a phase 2 randomized controlled trial comparing eight weeks of group online participation in Triple P: Positive Parenting Program with no intervention. RESULTS: The number of eligible parents who completed the intervention was low (31.6%). Main reasons for non consent or dropout were program time commitment too high or content not relevant. For parents who completed the intervention, satisfaction and acceptability was high. Parents reported the intervention as highly relevant and topical, feasible, helpful and a positive experience. Results indicated a non-significant trend towards improved total child behavioral and emotional difficulties following the intervention. Qualitative results indicated that intervention group parents reported improvements in parenting skills and competence, and decreased child behavioral problems. CONCLUSIONS: These pilot data highlight the difficulties of engaging and retaining parents in an 8-week parenting intervention in this context. For parents who completed the intervention, results indicated high feasibility, acceptability and satisfaction. Suggestions for further research and intervention modifications are provided to enhance uptake and strengthen efforts to assist parents in addressing child behavioral and emotional challenges during ALL treatment. PMID- 27697279 TI - Specialist nurse key worker in children's cancer care: Professionals' perspectives on the core characteristics of the role. AB - PURPOSE: To describe the development and implementation of the specialist nurse key worker role across 18 children's cancer centres in the United Kingdom, and draw out significant factors for success to inform future development of the role across a range of specialities. METHOD: Data were obtained through 42 semi structured interviews and a focus group with 12 key workers. Framework analysis revealed two main themes: models of care and key workers' perspectives of the role. RESULTS: Four models of care were identified and described, roles were organised along a continuum of in reach and outreach with either the presence or absence of home visits and direct delivery of clinical care. Key workers' perspectives of the advantages of the role included: coordination of care (being the main point of contact for families/professionals), experience and expertise (communication/information) and the relationship with families. The main challenges identified were: time, caseload size, geographical area covered, staffing numbers and resources available in the hospital and community. CONCLUSION: The label 'key worker' was disliked by many participants, as the loss of 'specialist nurse' in the title failed to reflect professional group. Leaving aside terminology, key workers shared core role elements within a continuum of in reach and outreach work and their involvement in direct clinical care varied throughout the pathway. Irrespective of the model they worked in, the key worker provided clinical, emotional, educational, and practical support to families, through the coordination of care, experience and expertise and relationship with families and professionals. PMID- 27697280 TI - The lived experience of patients in protective isolation during their hospital stay for allogeneic haematopoietic stem cell transplantation. AB - PURPOSE: Patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) usually receive hospital care in protective isolation until full neutrophil recovery. Although the aim of protective isolation is to benefit patients' health by preventing risks of infection, it could have severe psychological implications. The aim of this study was to explore the lived experiences of protective isolation in adult patients who had been treated with allogeneic HSCT. METHOD: A descriptive phenomenological inquiry based on Giorgi's approach was conducted in a university hospital in Italy. Ten patients (7 female and 3 male, age range 28-66), who had undergone allogeneic HSCT to treat a haematological malignancy, were interviewed about their hospital stay in protective isolation. RESULTS: A general meaning structure was identified as being isolated to achieve transformation. The revelatory themes were as follows: (1) the special place for transformation, (2) the experience of embodied transformation, and (3) light and shade from inside and outside. Participants experienced a transformation of themselves, of their relationships with loved ones, and of the environment. CONCLUSIONS: Since patients may live the experience of being treated with allogeneic HSCT in protective isolation as a transformation process, health-care providers should monitor the psychosocial implications of the isolation practice. PMID- 27697281 TI - The relationship between malignant wound status and pain in breast cancer patients. AB - PURPOSE: Skin metastasis is one of the most frequent metastases in breast cancer patients. Patients with malignant wounds experience numerous symptoms, including serious wound pain. However, the features of pain related to malignant wounds have not been investigated. Nurses can experience a dilemma when treating these patients due to a lack of knowledge of the pain. The aims of this study were to examine the quality and intensity of malignant wound pain and to determine the association between wound status and pain in the patients with malignant wounds. METHODS: Cross-sectional study was conducted. Participants were recruited from a breast centre based in a general hospital. We collected the patients' demographic and wound management data and assessed wound condition. Patients evaluated wound pain intensity and quality over the preceding week using the short-form McGill Pain Questionnaire (SF-MPQ). The association between SF-MPQ results, wound condition, and the time interval for wound care was evaluated using the Spearman's correlation coefficient. The protocol was approved by the Ethical Committee of the each facilities. RESULTS: The median age of the 22 enrolled patients was 61.5 years, and the median time after diagnosis of malignant wound was 15.5 months. Overall, 77.3% of patients complained of pain. Malignant wound pain significantly correlated with the degradation of wound edges, granulation tissue, and the time interval for wound care. CONCLUSION: We consider that it is necessary to provide pain-control care focused on the wound edge and granulation tissue of malignant wounds through the assessment of malignant wound pain and condition. PMID- 27697282 TI - How to get your research published. PMID- 27697283 TI - Effects of proximity to stormwater on the sandy-beach macrofaunal assemblages of metropolitan Adelaide, South Australia. AB - Stormwater run-off often enters coastal zones but its effects on sandy beaches are unknown. This study aimed to investigate associations between macrofaunal assemblages and proximity to stormwater outlets along Adelaide's beaches, comparing semi-natural creeks with concrete drains. Five positions along an increasing-salinity gradient were sampled in the intertidal zone of six stormwater outlets and also at corresponding control sites. There was no significant difference between the two forms of stormwater (semi-natural creeks with concrete drains). Only the largest outlet (Torrens) had a significant difference in assemblage structure and taxon richness compared to its control. Total abundances at this outlet followed a convex pattern across the salinity gradient, so it appears that flow there may have a spatially-limited positive effect on the macrofauna in terms of increasing abundance and richness. Therefore, the hypothesised detrimental effects of stormwater have not been found to be evident and these observed patterns warrant further investigation. PMID- 27697284 TI - Infection Dynamics of Foot-and-Mouth Disease Virus in Cattle Following Intranasopharyngeal Inoculation or Contact Exposure. AB - For the purpose of developing an improved experimental model for studies of foot and-mouth disease virus (FMDV) infection in cattle, three different experimental systems based on natural or simulated natural virus exposure were compared under standardized experimental conditions. Ante-mortem infection dynamics were characterized in cattle exposed to FMDV through a novel, simulated natural intranasopharyngeal (INP) inoculation system or through standardized and controlled systems of within- or between-species direct contact exposure (cattle to-cattle or pig-to-cattle). All three systems were efficient in causing synchronous, generalized foot-and-mouth disease in cattle exposed to one of three different strains of FMDV representing serotypes O, A and Asia1. There was more within-group variation in the timing of clinical infection following natural and simulated natural virus exposure systems when compared with the conventionally used system of needle inoculation (intraepithelial lingual inoculation). However, the three optimized exposure systems described herein have the advantage of closely simulating field conditions by utilizing natural routes of primary infection, thereby facilitating engagement of mucosal host defence mechanisms. Overall, it is concluded that INP inoculation and standardized systems of direct contact exposure provide effective alternatives to conventional (needle) inoculation systems for studies in which it is desirable to simulate the natural biology of FMDV infection. PMID- 27697285 TI - Vitamin D3 regulates LAMP3 expression in monocyte derived dendritic cells. AB - The family of lysosome-associated membrane proteins (LAMPs) encompassing LAMP1, LAMP2 and DC-LAMP (LAMP3) are the major constituents of the glycoconjugates coat present on the inside of the lysosomal membrane. LAMP3 is highly expressed only in certain cell types and during the differentiation stages. Its expression is linked the maturation of dendritic cells, inflammation, poor prognosis of certain tumors, and the locus where it is encoded was identified as a risk factor for Parkinson's disease (PD). Here, we investigated the capacity of Vitamin D3 to modulate the expression of LAMP3 during the dendritic cells differentiation and maturation. Our results demonstrated that the Vitamin D3 reduce the LAMP3 mRNA/protein expression during the dendritic cells differentiation and maturation, via NFkappaB pathways. Furthermore, we demonstrated that the Vitamin D3 was able to modulate the expression of LAMP3 likewise to in vitro tolerogenic dendritic cells. In summary, these data showed that the decrease of LAMP3 expression by Vitamin D3could enhance the tolerogenic characteristic of dendritic cells. PMID- 27697286 TI - The effect of transplanted human Wharton's jelly mesenchymal stem cells treated with IFN-gamma on experimental autoimmune encephalomyelitis mice. AB - Interferon gamma (IFN-gamma) increases the immunosuppressive property of human Wharton's jelly mesenchymal stem cells (hWJ-MSCs). In this study, we evaluated the therapeutic effects of IFN-gamma primed WJ-MSCs in EAE mice. IFN-gamma primed WJ-MSCs were injected on days 3 and 11 after EAE induction. 21 days after EAE induction, splenocytes and cervical lymph node cells were isolated and cell proliferation, secretion of inflammatory cytokines and frequency of regulatory T cells was measured. On day 50 of the study, cell infiltration and gene expression of inflammatory cytokines in brain of mice were studied. Leukocyte infiltration and symptoms were significantly reduced in IFN-gamma primed WJ-MSCs treated group compared to other groups. These cells showed significantly reduced proliferation and increased Treg cells as well as decreased secretion and gene expression of inflammatory cytokines in EAE mice. Our data suggest that IFN-gamma may be used to stimulate the immunomodulatory property of WJ-MSCs in clinical situations. PMID- 27697287 TI - The generalizability of NCI-sponsored clinical trials accrual among women with gynecologic malignancies. AB - OBJECTIVES: Enrollment of a representative population to cancer clinical trials ensures scientific reliability and generalizability of results. This study evaluated the similarity of patients enrolled in NCI-supported group gynecologic cancer trials to the incident US population. METHODS: Accrual to NCI-sponsored ovarian, uterine, and cervical cancer treatment trials between 2003 and 2012 were examined. Race, ethnicity, age, and insurance status were compared to the analogous US patient population estimated using adjusted SEER incidence data. RESULTS: There were 18,913 accruals to 156 NCI-sponsored gynecologic cancer treatment trials, ovarian (56%), uterine (32%), and cervical cancers (12%). Ovarian cancer trials included the least racial, ethnic and age diversity. Black women were notably underrepresented in ovarian trials (4% versus 11%). Hispanic patients were underrepresented in ovarian and uterine trials (4% and 5% versus 18% and 19%, respectively), but not in cervical cancer trials (14 versus 11%). Elderly patients were underrepresented in each disease area, with the greatest underrepresentation seen in ovarian cancer patients over the age of 75 (7% versus 29%). Privately insured women were overrepresented among accrued ovarian cancer patients (87% versus 76%), and the uninsured were overrepresented among women with uterine or cervical cancers. These patterns did not change over time. CONCLUSIONS: Several notable differences were observed between the patients accrued to NCI funded trials and the incident population. Improving representation of racial and ethnic minorities and elderly patients on cancer clinical trials continues to be a challenge and priority. PMID- 27697288 TI - Serum, uterine, and vaginal mucosal IgG antibody responses against Tritrichomonas foetus after administration of a commercial killed whole T foetus vaccine in beef cows. AB - The objective of this study was to determine the level and duration of IgG antibodies induced against killed whole Tritrichomonas foetus and T foetus purified surface antigen (TF1.17) in serum, vaginal, and uterine secretions after systemic immunization of beef cows with a vaccine containing killed whole T foetus. Twenty nonpregnant beef cows were randomly assigned to vaccine or control groups as follows: Vaccine (n = 10): cows received 2 mL of a commercial vaccine containing killed whole T foetus subcutaneously and a 2-mL booster 2 weeks later. Control (n = 10): cows received 2 mL of sterile saline on the same schedule. Vaginal secretions and blood samples were collected on Days 0, 8, 15, 22, 29, 36, 43, 50, 60, 75, 89, 110, 146, and 182 relative to day of primary vaccination. Uterine flush fluid was collected on Days 0, 15, 29, and 43 after the day of primary vaccination. Samples were assayed for IgG antibodies to the killed whole T foetus and surface antigen TF1.17 using enzyme-linked immunosorbent assay. Serum whole T foetus-specific IgG levels were significantly increased (between Days 15 and 182) following vaccination with T foetus or with saline. No differences between vaccinates and controls in uterine responses to whole-cell antigen were detected. Serum anti-TF1.17 IgG responses to vaccination were significantly higher than Day 0 throughout the immunization period (P < 0.001) and were higher than responses in control animals on each day post immunization through Day 146 (P < 0.001). A significant rise in TF1.17-specific IgG levels was observed in vaginal and uterine fluids from Day 15 post vaccination compared to the Day 0 levels. These levels remained significantly elevated in vaginal and uterine fluids through Days 75 (P < 0.05) and 43 (P < 0.001) after primary vaccination, respectively. Antibody levels in serum, vaginal, and uterine secretions against TF1.17 remained low in the control group throughout the study. In conclusion, vaccination of beef cows with a commercial vaccine containing T foetus induced significant increase in the levels of IgG to the T foetus TF1.17 surface antigen in serum, vaginal secretions, and uterine fluid, which remained elevated through Days 43, 75, and 182 in uterine fluids, vaginal secretions, and serum, respectively. Since purified TF1.17 antigen has been shown to protect against experimental T foetus infection in heifers, the vaccine-induced TF1.17 specific IgG response is likely to be important in the prevention of trichomoniasis in beef cattle.

AB - Microglia are the resident immune cells in the central nervous system and many of their physiological functions are known to be linked to intracellular calcium (Ca2+) signaling. Here we show that isolated and purified mouse microglia-either freshly or cultured-display spontaneous and transient Ca2+ elevations lasting for around ten to twenty seconds and occurring at frequencies of around five to ten events per hour and cell. The events were absent after depletion of internal Ca2+ stores, by phospholipase C (PLC) inhibition or blockade of inositol-1,4,5 trisphosphate receptors (IP3Rs), but not by removal of extracellular Ca2+, indicating that Ca2+ is released from endoplasmic reticulum intracellular stores. We furthermore provide evidence that autocrine ATP release and subsequent activation of purinergic P2Y receptors is not the trigger for these events. Spontaneous Ca2+ transients did also occur after stimulation with Lipopolysaccharide (LPS) and in glioma-associated microglia, but their kinetics differed from control conditions. We hypothesize that spontaneous Ca2+ transients reflect aspects of cellular homeostasis that are linked to regular and patho physiological functions of microglia.

AB - BACKGROUND AND OBJECTIVE: Parkinson's disease (PD) is the second most common neurodegenerative disease, and the etiology of its sporadic form is unknown. The present study analyzes the temporal and spatial variations of mortality by PD in Spain over a period of 14 years and its relationship with lead concentration levels in the atmosphere. METHOD: An ecological study was performed, in which deaths by PD and age group in 50 Spanish provinces between 2000 and 2013 were analyzed. The annual trend of PD mortality was assessed using the non-parametric Spearman's Rho test. Finally, the relationship between lead concentration levels in the air and mortality by PD was evaluated. RESULTS: Between 2000 and 2013, 36,180 patients with PD died in Spain. There is an increasing trend in mortality through PD over the study period (P<.0001). La Rioja, Asturias, Basque Country and the Lower Ebro valley were the regions with the highest values of PD mortality. Those regions with the highest lead concentrations also showed higher mortality by this disease in people over 64 (P=.02). CONCLUSIONS: Over our period of study, there has been an increase in mortality through PD in Spain, with the northernmost half of the country registering the highest values. Mortality in men was higher than mortality in women. Moreover, a direct correlation was found between lead levels in the air and mortality through PD. PMID- 27697292 TI - Promotion of nutrition care by Australian fitness businesses: a website analysis. AB - OBJECTIVES: To investigate the intention of fitness businesses to promote the provision of nutrition care from personal trainers. STUDY DESIGN: Cross-sectional evaluation of webpage content. METHODS: Fitness businesses within two Australian federal electorates were identified using the Fitness Australia list of registered fitness businesses. Inductive content analysis of these fitness business websites and associated social media sites was undertaken to compare website content to the Fitness Australia Position Statement outlining the Roles and Responsibilities of Registered Fitness Professionals. Fitness businesses were classified as 'within scope of practice' if they referred to national nutrition guidelines or dietetic services. 'At risk of being beyond scope' included websites which did not include enough information to definitively state within or beyond scope. Fitness businesses were classified as 'definitely beyond scope of practice' if they advertised nutrition care which clearly extended beyond translation of the national dietary guidelines. RESULTS: Of the businesses reviewed, 15% were within scope despite none referring to a dietitian; 34% were at risk of being beyond scope; and 51% were beyond scope as they advertised nutrition care such as personalized diets without indicating dietetic input. CONCLUSIONS: A considerable portion of fitness businesses reviewed advertised their personal trainers as able to provide nutrition care outside the recommended scope of practice. Strategies that help fitness businesses and personal trainers to support clients to have healthy dietary behaviours without extending outside the scope of practice are warranted.

AB - Detailed biochemical and biophysical characterization of viruses requires viral preparations of high quantity and purity. The optimization of virus production and purification is an essential, but laborious and time-consuming process. Asymmetric flow field flow fractionation (AF4) is an attractive alternative method for virus purification because it is a rapid and gentle separation method that should preserve viral infectivity. Here we optimized the AF4 conditions to be used for purification of a model virus, bacteriophage PRD1, from various types of starting materials. Our results show that AF4 is well suited for PRD1 purification as monitored by virus recovery and specific infectivity. Short analysis time and high sample loads enabled us to use AF4 for preparative scale purification of PRD1. Furthermore, we show that AF4 enables the rapid real-time analysis of progeny virus production in infected cells. PMID- 27697295 TI - Information-Based Approaches of Noninvasive Transcranial Brain Stimulation. AB - Progress in cognitive neuroscience relies on methodological developments to increase the specificity of knowledge obtained regarding brain function. For example, in functional neuroimaging the current trend is to study the type of information carried by brain regions rather than simply compare activation levels induced by task manipulations. In this context noninvasive transcranial brain stimulation (NTBS) in the study of cognitive functions may appear coarse and old fashioned in its conventional uses. However, in their multitude of parameters, and by coupling them with behavioral manipulations, NTBS protocols can reach the specificity of imaging techniques. Here we review the different paradigms that have aimed to accomplish this in both basic science and clinical settings and follow the general philosophy of information-based approaches. PMID- 27697296 TI - Internal and external validation of an ESTRO delineation guideline - dependent automated segmentation tool for loco-regional radiation therapy of early breast cancer. AB - BACKGROUND AND PURPOSE: To internally and externally validate an atlas based automated segmentation (ABAS) in loco-regional radiation therapy of breast cancer. MATERIALS AND METHODS: Structures of 60 patients delineated according to the ESTRO consensus guideline were included in four categorized multi-atlas libraries using MIM MaestroTM software. These libraries were used for auto segmentation in two different patient groups (50 patients from the local institution and 40 patients from other institutions). Dice Similarity Coefficient, Average Hausdorff Distance, difference in volume and time were computed to compare ABAS before and after correction against a gold standard manual segmentation (MS). RESULTS: ABAS reduced the time of MS before and after correction by 93% and 32%, respectively. ABAS showed high agreement for lung, heart, breast and humeral head, moderate agreement for chest wall and axillary nodal levels and poor agreement for interpectoral, internal mammary nodal regions and LADCA. Correcting ABAS significantly improved all the results. External validation of ABAS showed comparable results. CONCLUSIONS: ABAS is a clinically useful tool for segmenting structures in breast cancer loco-regional radiation therapy in a multi-institutional setting. However, manual correction of some structures is important before clinical use. The ABAS is now available for routine clinical use in Danish patients. PMID- 27697297 TI - Immunohistochemistry of apoptosis-related proteins in retinoblastoma. AB - Retinoblastoma is the most common intraocular malignant neoplasia during childhood and results from the partial or total inactivity of the retinoblastoma protein (pRb). In the absence of pRb, the E2F transcription factors increase the levels of cell cycle proteins as well as some pro-apoptotic proteins. We intended to study the immunohistochemistry profile of apoptotic-related proteins in retinoblastoma. We also evaluated the association between the expression of apoptotic protein and stage of tumor or survivor after a 5year follow up. Apoptosis-related proteins (Apaf-1, Bak, Bax, Bcl-2, Bcl-xL, Bim-long, MDM2, p53, pro-caspase-3, PUMA, Smac/DIABLO and cleaved caspase-3) were evaluated using immunohistochemistry on tissue microarrays which contained samples of retinoblastoma tumors taken from ninety-three patients without any treatment previous to surgery. The immunohistochemistry reactions were evaluated using an optical microscope as well as the ACIS III(r) platform. The pro-apoptotic proteins (APAF-1, Bax, p53, PUMA, Smac/DIABLO) were more frequently expressed than the anti-apoptotic proteins (Bcl-2, Bcl-xL and MDM2). The protein Bcl-xL had a negative correlation with cleaved caspase-3, a marker of cell apoptosis. Bcl-xL may be implicated in an apoptosis block.

PMID- 27697299 TI - Transcriptional regulation of inflammasome-associated pattern recognition receptors, and the relevance to disease pathogenesis. AB - Over the last decade it has emerged that inflammasome complexes provide a pivotal platform for the host innate immune system to respond to exogenous infectious microbes (viruses, bacteria, fungi) and non-infectious environmental agents (cigarette smoke, pollution), as well as endogenous "danger" signals. Upon the canonical activation of inflammasomes, a key effector function is to catalyze, via caspase-1, the maturation of the potent pro-inflammatory cytokines interleukin (IL)-1beta and IL-18, which, in addition to chronic inflammatory responses have also been intimately linked to the inflammatory form of lytic cell death, pyroptosis. However, recent evidence suggests that inflammasomes exhibit marked pleiotropism beyond their canonical functions, whereby their activation can also influence a large number of cellular responses including proliferation, apoptosis, autophagy and metabolism. It is therefore not surprising that the dysregulated expression and/or activation of inflammasomes is increasingly implicated in numerous disease states, such as chronic auto-inflammatory and autoimmune disorders, metabolic syndrome, neurodegenerative and cardiovascular diseases, as well as cancer. In this review we will highlight recent advancements in our understanding of the transcriptional regulation of genes encoding inflammasome-associated innate immune receptors, and the impact on a variety of cellular responses during disease pathogenesis.

PMID- 27697301 TI - [Is there a disassociation of ventilatory and electromyographic thresholds in patients with heart disease during a graded cycling exercise?] AB - : Exercise prescription was generally based on the determination of ventilatory thresholds (VT1, VT2) during cardiopulmonary exercise testing (CPX). Changes in surface electromyographic activity (EMGth1, EMGth2) were also related to VT1 and VT2 in healthy subjects. OBJECTIVE: To observe the occurrence of EMGth1 and EMGth2 and whether these events accompany VT1 and VT2 during CPX in cardiac patients (CP). METHOD: Thirty-four CP (62.1+/-7.3years, 172.1+/-6.3cm, 81.3+/ 15.3kg, BMI: 27.3+/-4.1) performed a cycle CPX at a 60-rpm cadence. VT1 was determined as the breakpoint in the curve of carbon dioxide output against oxygen uptake plot (V-slope method). VT2 was defined as the point at which the ratio of minute ventilation to carbon dioxide output starts to increase. The root mean square of electromyogram (rms-EMG) was on-line calculated from the real time bipolar surface electromyographic signals recorded from the vastus lateralis. EMGth1 and EMGth2 were defined as the first and the second breakpoints in the rms EMG-power output relationship. RESULTS: Peak values of oxygen uptake (16.3+/ 4.6mL.min-1.kg-1) and heart rate (106.7+/-13.8bpm) were reached at 112.9+/-38.5w (PMT). VT1 and VT2 occurred at 71.1+/-25.9w (62.5+/-5.5% PMT) and 87.9+/-28.6w (78.0+/-5.1% PMT). All subjects presented two breakpoints in the rms-EMG curve, EMGth1 at 68.0+/-24.7w and EMGth2 at 88.5+/-30.1w, i.e. 60.0+/-7.6 and 78.6+/ 5.0% of PMT. EMGth1 occurred significantly before VT1 (P=0.004, small effect size). No significant difference was observed between EMGth2 and VT2 (P=0.13, small effect size). CONCLUSION: The EMGth1 occurrence before VT1 suggested a role of skeletal muscle conditioning on ventilatory responses, which should be taken into account in cardiac rehabilitation program prescription. PMID- 27697303 TI - Existing equations to estimate lean body mass are not accurate in the critically ill: Results of a multicenter observational study. AB - BACKGROUND & AIMS: Lean body mass (LBM), quantified using computed tomography (CT), is a significant predictor of clinical outcomes in the critically ill. While CT analysis is precise and accurate in measuring body composition, it may not be practical or readily accessible to all patients in the intensive care unit (ICU). Here, we assessed the agreement between LBM measured by CT and four previously developed equations that predict LBM using variables (i.e. age, sex, weight, height) commonly recorded in the ICU. METHODS: LBM was calculated in 327 critically ill adults using CT scans, taken at ICU admission, and 4 predictive equations (E1-4) that were derived from non-critically adults since there are no ICU-specific equations. Agreement was assessed using paired t-tests, Pearson's correlation coefficients and Bland-Altman plots. RESULTS: Median LBM calculated by CT was 45 kg (IQR 37-53 kg) and was significantly different (p < 0.001) from E1 (52.5 kg; IQR: 42-61 kg), E2 (55 kg; IQR 45-64 kg), E3 (55 kg; IQR 44-64 kg), and E4 (54 kg; IQR 49-61 kg). Pearson correlation coefficients suggested moderate correlation (r = 0.739, 0.756, 0.732, and 0.680, p < 0.001, respectively). Each of the equations overestimated LBM (error ranged from 7.5 to 9.9 kg), compared with LBM calculated by CT, suggesting insufficient agreement. CONCLUSIONS: Our data indicates a large bias is present between the calculation of LBM by CT imaging and the predictive equations that have been compared here. This underscores the need for future research toward the development of ICU-specific equations that reliably estimate LBM in a practical and cost-effective manner. PMID- 27697302 TI - A phase 1, randomized, controlled dose-escalation study of EP-1300 polyepitope DNA vaccine against Plasmodium falciparum malaria administered via electroporation. AB - : Plasmodium falciparum malaria is one of the leading infectious causes of childhood mortality in Africa. EP-1300 is a polyepitope plasmid DNA vaccine expressing 38 cytotoxic T cell epitopes and 16 helper T cell epitopes derived from P. falciparum antigens expressed predominantly in the liver phase of the parasite's life cycle. We performed a phase 1 randomized, placebo-controlled, dose escalation clinical trial of the EP-1300 DNA vaccine administered via electroporation using the TriGrid Delivery System device (Ichor Medical Systems). Although the delivery of the EP-1300 DNA vaccine via electroporation was safe, tolerability was less than that usually observed with standard needle and syringe intramuscular administration. This was primarily due to acute local discomfort at the administration site during electroporation. Despite the use of electroporation, the vaccine was poorly immunogenic. The reasons for the poor immunogenicity of this polyepitope DNA vaccine remain uncertain. CLINICAL TRIALS REGISTRATION: ClinicalTrials.gov NCT01169077. PMID- 27697304 TI - Neurodevelopmental outcome of term infants with perinatal asphyxia with hypoxic ischemic encephalopathy stage II. AB - BACKGROUND: Perinatal asphyxia with hypoxic ischemic encephalopathy (HIE) causes significant mortality and morbidity in developing countries. There is limited information about long term neurodevelopmental outcome of infants with neonatal encephalopathy. METHODS: Term infants with the diagnosis of perinatal asphyxia were followed up in neurodevelopmental clinics of Manipal Teaching hospital, Nepal. Study design was prospective mixed longitudinal study. Prematurity, major congenital malformations, other intracranial pathology, birth weight <2500g and chromosomal abnormalities were excluded. After consent and enrollment their detailed perinatal history, Apgar score, resuscitation measures and outcome parameters were recorded on a predesigned proforma. Developmental assessment was done with Denver Developmental Screening Tool 2nd edition (DDST 2) at the age of 3months, 6months, 9months, 1year, 18months and 2years. RESULTS: Total 187 assessments done in the age group of 3months to 2years among HIE stage 2 patients. Impaired hearing and vision was noted in 5.3% while language delay was observed in 19.2% of infants. Abnormal tone and deep tendon reflexes were noted in 46.2% infants at 3months. Abnormal tone and reflexes were noted only in 18.8% and 9.4% respectively at the age of 2years. Overall, gross motor delay was noted in 55(29.4%) of patient, 34(18.2%) showed fine motor delay and 17.1% social delay. Seizures were persistent in 15.6% patients at 2years age. CONCLUSION: Infants affected with HIE have delay in all sectors of developmental milestones. Motor abnormalities are common and tend to improve with advancing age. PMID- 27697305 TI - Early cardiac involvement in an infantile Sandhoff disease case with novel mutations. AB - INTRODUCTION: Hepatosplenomegaly is often present in infantile Sanshoff disease. However, cardiac involvement is extremely uncommon. CASE REPORT: We describe a 14 month-old female baby who exhibited mitral regurgitation and cardiomegaly at the age of 2months, dilation of the left atrium and left ventricle at age of 6months, followed by regression of developmental milestones after an episode of minor infection at age of 14months. Brain magnetic resonance imaging revealed signal changes over the bilateral thalami, bilateral cerebral white matter and left putamen. An examination of the fundus showed presence of cherry-red spots in both macular areas. The lysosomal enzymatic activities showed a marked reduction of beta-hexosaminidase B (HEXB) activity. Two novel mutations of HEXB gene were identified. One of the mutations was a c.1538 T>C mutation, which predicted a p.L513P amino acid substitution of leucine to proline; the other was a c.299+5 G>A mutation, which was a splice site mutation. CONCLUSION: Cardiac involvement might occur prior to neurological symptoms in infantile Sandhoff disease, and it should be included in the differential diagnoses of metabolic cardiomyopathies in the infantile stage. PMID- 27697306 TI - The relationship between motor proficiency and mental health outcomes in young adults: A test of the Environmental Stress Hypothesis. AB - Growing evidence has highlighted the importance of motor proficiency in relation to psychosocial outcomes including self-perceived competence in various domains, perceived social support, and emotional areas such as anxiety and depression. The Environmental Stress Hypothesis-elaborated (Cairney, Rigoli, & Piek, 2013) is a proposed theoretical framework for understanding these relationships and recent studies have begun examining parts of this model using child and adolescent populations. However, the extent to which the relationships between these areas exist, persist or change during early adulthood is currently unclear. The current study aimed to investigate the Environmental Stress Hypothesis in a sample of 95 young adults aged 18-30years and examined the mediating role of physical self worth and perceived social support in the relationship between motor proficiency and internalising symptoms. The McCarron Assessment of Neuromuscular Development (McCarron, 1997) was used to assess motor proficiency, the Depression Anxiety Stress Scale (Lovibond & Lovibond, 1995) provided a measure of internalising symptoms, and the Physical Self Perceptions Profile (Fox & Corbin, 1989) and the Multidimensional Scale of Perceived Social Support (Zimet, Dahlem, Zimet, & Farley, 1988) were used to investigate the possible mediating role of physical self-worth and perceived social support respectively. Potential confounding variables such as age, gender and BMI were also considered in the analysis. Structural Equation Modelling revealed that perceived social support mediated the relationship between motor proficiency and internalising symptoms, whereas, the mediating role of physical self-worth was non-significant. The current results provide support for part of the model pathways as described in the Environmental Stress Hypothesis and suggest an important relationship between motor proficiency and psychosocial outcomes in young adults. Specifically, the results support previous literature regarding the significant role of perceived social support for mental well-being and suggest that an intervention that considers social support may also indirectly influence mental health outcomes in young adults who experience movement difficulties.

PMID- 27697309 TI - Recurrence factors and prevention of complications of pediatric differentiated thyroid cancer. AB - BACKGROUND/OBJECTIVE: To investigate the factors associated with recurrence of differentiated thyroid cancer in children. We combined the clinical and pathological features to guide surgical treatment options, ensure efficacy, and reduce complications. METHODS: A prospective analysis of clinical data of 43 cases of pediatric differentiated thyroid cancer from March 2008 to June 2014 admitted in our department, including 38 cases of papillary cancers and five cases of follicular cancer; 40 cases were Stage I and three cases were Stage II (Union for International Cancer Control [UICC] Tumor Node Metastasis classification [TNM] staging). We performed the operations according to the condition of lesions and lymph nodes. Operations included subtotal resection in 36 cases, total resection in seven cases. We applied statistical methods to investigate the risk factors of recurrence and postoperative complications. RESULTS: The pathologic lymph node metastasis rate was 67.44% (29/43): Area VI lymph nodes metastases in 20 cases and Area III/IV or Area II/V lymph nodes metastases in nine cases. Postoperative hypocalcemia symptoms were seen in three cases and hoarseness in three cases, for a total rate of 13.95% (6/43). Until December 2015, patients were followed up from 1.5 years to 8.7 years, with a median of 4.9 years. There were three cases of cervical lymph node recurrence, one case of local recurrence, and one case of lung metastasis, for a total recurrence rate of 11.63% (5/43); all patients survived. Log-rank test of Kaplan Meier curves and Cox stepwise regression analysis showed that lesion number, extrathyroidal extension, and lymph nodes metastases were the risk factors for postoperative recurrence; the relative risk values were, respectively, 3.117, 2.816, and 4.628 (p=0.041, p=0.048, and p=0.031, respectively) and the 95% confidence intervals (CI) were, respectively, 1.094~8.735, 1.046~7.932, and 1.189~10.205. However, the lesion excision approach was not a risk factor for postoperative recurrence (p=0.107). The logistic stepwise regression model showed that lesion excision approach was a risk factor for postoperative hypocalcemia and hoarseness; the odds ratio value was 2.537 (p=0.037) and the 95% CI was 1.034~6.983. CONCLUSION: Pediatric differentiated thyroid cancer has a high metastatic rate to lymph nodes and distant organs, but the total prognosis is good. Application of total resection cannot necessarily reduce the relapse rate of pediatric differentiated thyroid cancer, but it may increase the postoperative hypocalcemia and hoarseness. The authors propose strictly adhering to various operation indicators, and carrying out various operations with a full understanding of the local lesion and lymph nodes in order to reduce relapse and postoperative complications. PMID- 27697308 TI - Calcific aortic stenosis and its correlation with a novel inflammatory marker, the lymphocyte/monocyte ratio. AB - INTRODUCTION: Calcific aortic valve disease, a chronic progressive disorder, is the leading cause of valve replacement among elderly patients. The lymphocyte/monocyte ratio has been recently put forward as an inflammatory marker of relevance in several cancers as well as in cardiovascular disease. This study aims to assess the correlation between severity of calcific aortic stenosis and the lymphocyte/monocyte ratio. METHODS: The study retrospectively included 178 patients with a diagnosis of calcific aortic stenosis and 139 age- and gender matched controls. The patients were divided into two groups according to the severity of aortic stenosis: mild-to-moderate and severe. RESULTS: An inverse correlation was discerned between the severity of the aortic stenosis process (mean gradient) and the lymphocyte/monocyte ratio (r=-0.232, p=0.002). The lymphocyte/monocyte ratio was observed to decrease as the severity of aortic stenosis increased (p<0.001) in the group with severe aortic stenosis compared with the mild-to-moderate aortic stenosis and control groups (p<0.001, p=0.005 respectively), and in the group with mild-to-moderate aortic stenosis compared with the control group (p=0.003). Multivariate regression analysis revealed that the lymphocyte/monocyte ratio was independently related to the severity of calcific aortic stenosis (p=0.003). CONCLUSION: The present study demonstrated the existence of a statistically significant inverse relationship between severity of calcific aortic stenosis and the lymphocyte/monocyte ratio. The study also revealed that the lymphocyte/monocyte ratio was significantly related to the severity of the aortic valve stenosis process. PMID- 27697310 TI - Comprehensive study on the effects of sodium and potassium additives in size exclusion chromatographic separations of protein biopharmaceuticals. AB - To separate proteins solely based on their difference in hydrodynamic volume in size exclusion chromatography (SEC), the ionic strength of the mobile phase has to be increased in order to avoid secondary ionic interactions between proteins and the stationary phase. However, adding salts to the mobile phase can have a serious effect on protein aggregation and can lead to artifacts. In the present study, several monoclonal antibodies (mAbs) and the antibody-drug conjugate (ADC), trastuzumab emtansine were selected to study the effect of mobile phase salt additive on aggregation measurements. In a first instance, the same aggregation ratios between the dimeric and monomeric forms of ten mAbs approved by the Food and Drug Administration (FDA) and the European Medicine Agency (EMA) were obtained with three UHP-SEC columns. However, SEC analysis using various amounts of NaCl provided surprising results for rituximab, e.g. presence of 0.8% aggregates with a mobile phase containing 0.2M NaCl, while no aggregates were observed without NaCl in the mobile phase. Despite the absence of monomeric protein adsorption at the surface of the SEC resin, the comparison of sodium- and potassium-based salts demonstrated the superiority of potassium-based salts to reduce possible secondary electrostatic interactions, mainly between protein dimers and the SEC support as well as to lower protein-salts interaction. To investigate the effect of mobile phase salt additives on SEC measurements, fluorescence spectroscopy provided insights related to the possible contribution of protein tertiary structure. Indeed, biopharmaceuticals could be classified depending on the exposure of their tryptophan residues to the solvent in order to understand their propensity to interact with the stationary phase or/and to undergo self-association.

AB - BACKGROUND: Adult and pediatric patients suffering from MuSK (muscle-specific kinase) -antibody positive myasthenia gravis exhibit similar features to individuals with acetylcholine receptor (AChR) antibodies, but they differ in several characteristics such as a predominant bulbar, respiratory and neck weakness, a generally worse disease severity and a tendency to develop muscle atrophy. Muscle atrophy is a rare phenomenon that is usually restricted to the facial muscles. RESULTS: We describe a girl with MuSK-antibody positive myasthenia gravis who developed a myopathy with severe generalized muscular weakness, muscle atrophy, and myopathic changes on electromyography. CONCLUSION: This is the first published example of a generalized myopathic syndrome in myasthenia gravis. We review the relevant literature and discuss the hypothesis of a mitochondrial myopathy as a pathogenic mechanism in MuSK-antibody positive myasthenia gravis. PMID- 27697313 TI - Treatment of Neurogenetic Developmental Conditions: From 2016 into the Future. AB - BACKGROUND: Neurogenetic developmental conditions represent a heterogeneous group of rare inherited disorders with neurological manifestation during development. Treatments for these conditions have largely been supportive; however, a number of treatments are emerging which target the underlying physiology and offer great potential. Our aim was to present a state-of-the-art overview of the current and potential causal treatments available or under development for neurogenetic developmental conditions. METHODS: In this review, we focus on the following neurogenetic developmental conditions: (1) inborn errors of metabolism causing neurogenetic developmental conditions, (2) fragile X syndrome, (3) Rett syndrome, (4) tuberous sclerosis complex, 5) Down syndrome and other neurogenetic developmental conditions. RESULTS: A large group of inborn errors of metabolism leads to neurodevelopmental disability, affecting the central nervous system during infancy or childhood and can present with comorbidities such as intellectual developmental disability, epilepsy, atypical cerebral palsy, autism spectrum disorder, behavioral and psychiatric disturbances, for which causal treatments are discussed. CONCLUSIONS: The advent of these new disease-modifying therapies has the potential to reverse the underlying neural mechanisms of these debilitating conditions, which may provide prospect to affected individuals.

PMID- 27697315 TI - Comparison of short-term clinical outcomes between transanal and laparoscopic total mesorectal excision for the treatment of mid and low rectal cancer: A meta analysis. AB - AIM: The objective of this meta-analysis was to evaluate the feasibility, safety, and short-term clinical outcomes of transanal total mesorectal excision (TaTME) comparing with laparoscopy total mesorectal excision (LapTME) for mid and low rectal cancer. METHODS: Relevant studies were searched from the databases of Pubmed, Embase, and the Cochrane Library. The qualities of all of the included studies were evaluated using Newcastle-Ottawa Scale (NOS). The synthesized outcomes were pooled using fixed-effects models or random-effects models, which weighted the odds ratio (OR) or mean difference (MD) with 95% confidence intervals (95% CI). A funnel plot was used to evaluate the publication bias. RESULTS: Seven original studies including 209 TaTME patients and 257 LapTME patients with rectal cancer met the inclusion criteria in this meta-analysis. Compared with LapTME, TaTME showed a longer CRM, lower rate of positive CRM, complete TME rate, and less operative time. There were no significant differences in the outcomes of the harvested lymph nodes, distal margin distance, hospital stay, intraoperative complications, anastomotic leakage, postoperative complications, reoperation, readmission, or conversion between the TaTME group and the LapTME group. CONCLUSIONS: Compared with LapTME, TaTME is a feasible and safe approach for patients with mid and low rectal cancer. In addition, TaTME showed a better short-term clinical outcomes, such as a longer CRM, lower risk of positive CRM, higher complete quality of TME rate, and shorter operative duration. Further prospective studies with long-term follow-up are required. PMID- 27697316 TI - Time-driven activity-based costing to identify opportunities for cost reduction in pediatric appendectomy. AB - PURPOSE: As reimbursement programs shift to value-based payment models emphasizing quality and efficient healthcare delivery, there exists a need to better understand process management to unearth true costs of patient care. We sought to identify cost-reduction opportunities in simple appendicitis management by applying a time-driven activity-based costing (TDABC) methodology to this high volume surgical condition. METHODS: Process maps were created using medical record time stamps. Labor capacity cost rates were calculated using national median physician salaries, weighted nurse-patient ratios, and hospital cost data. Consumable costs for supplies, pharmacy, laboratory, and food were derived from the hospital general ledger. RESULTS: Time-driven activity-based costing resulted in precise per-minute calculation of personnel costs. Highest costs were in the operating room ($747.07), hospital floor ($388.20), and emergency department ($296.21). Major contributors to length of stay were emergency department evaluation (270min), operating room availability (395min), and post-operative monitoring (1128min). The TDABC model led to $1712.16 in personnel costs and $1041.23 in consumable costs for a total appendicitis cost of $2753.39. CONCLUSION: Inefficiencies in healthcare delivery can be identified through TDABC. Triage-based standing delegation orders, advanced practice providers, and same day discharge protocols are proposed cost-reducing interventions to optimize value-based care for simple appendicitis.

Previous reports have been single cases or small series. We previously reported a small multicenter review with encouraging early results. We now describe our matured experience. METHODS: This is a follow-up study of patients with SRS from 2006 to 2015. Included are 5 previously analyzed patients and 25 new patients. Patients were called to review current symptoms, course, and satisfaction. RESULTS: From 2006 to 2015, 30 patients underwent 38 operations. Eight underwent re-operation. All had reproducible pain localized to the costal margin, 60% had a popping sensation, and 23% were bilateral. 86% were female. Median age of symptom onset was 14 (IQR 13.75-15) years, while median age at diagnosis was 16 (IQR 15-17). Contact was possible with 18/30 patients, and mean follow up time was 1.3years. 72% of those felt they were cured, and 44% rated satisfaction a 10/10 (mean 7.84). Of those not cured, all reported significant improvement. CONCLUSIONS: Costal cartilage excision is an effective treatment for SRS and should be considered early in the workup of costal margin pain in a normally active population.

AB - BACKGROUND: Congenital portosystemic shunts (CPSS) with intrahepatic portal vein (IHPV) hypoplasia or absence cause encephalopathy or pulmonary hypertension (PH). Acute shunt closure may result in postoperative portal hypertension. The aim of this study was to propose a surgical strategy according to the anatomical types of CPSS and IHPV. METHODS: Twenty-three CPSS patients were diagnosed from1990 to 2015. All patients were evaluated by computed tomography, angiography, and PV pressure monitoring under a shunt occlusion test. CPSS were categorized into 5 types according to the anatomical shunt location. RESULTS: The median age at diagnosis was 34months. Three of 23 total patients, who had an extrahepatic portosystemic shunt with a hypoplastic IHPV, died before treatment initiation because of severe PH. Fourteen cases received surgical or interventional treatment at the median age of 5years. A total of 6 cases received surgical therapy, including liver transplants for 2 absent IHPV cases. The remaining 8 cases received interventional coiling. All shunt ligations were successfully accomplished in 1-stage ligation without any complications. After the treatment, the hypoplastic IHPV gradually enlarged with an efficient portal inflow. CONCLUSION: A precise pretreatment anatomical evaluation of CPSS and IHPV types is mandatory for the selection of surgical treatment.

PMID- 27697320 TI - Is climate change an unforeseen, irresistible and external factor - A force majeure in marine environmental law? AB - Several environmental laws include provisions on natural causes or force majeure, which except States from their commitments if it can be proven that the failure to meet the commitment is due to factors outside their control. The European Union Marine Strategy Framework Directive (MSFD) has a pivotal role in managing EU marine waters. This paper analyses natural causes and force majeure provisions of the MFSD and other marine legislation, and addresses their interaction with climate change and its consequences, especially the effect on the obligation of ensuring seas are in Good Environmental Status. Climate change is an exogenic unmanaged pressure in that it emanates from outside the area being managed but in which the management authority has to respond to the consequences of climate change, such as sea level rise and temperature elevation, rather than its causes. It is suggested that a defence by a Member State of force majeure may be accepted if an event was proven to be due to an externality of control, irresistible and unforeseeable. The analysis contends that countering such a legal defence would centre on the fact that climate change is a well-accepted phenomenon, is foreseen with an accepted level of confidence and probability and is due to human actions. However, as yet, this has not been legally tested. PMID- 27697319 TI - Benthic foraminifera as bio-indicators of chemical and physical stressors in Hammerfest harbor (Northern Norway). AB - We investigated benthic foraminiferal assemblages in contaminated sediments in a subarctic harbor of Northern Norway to assess their utility as indicators of anthropogenic impacts. Sediments in the harbor are repositories for POPs and heavy metals supplied through discharges from industry and shipping activities. Sediment contaminant concentrations are at moderate to poor ecological quality status (EcoQS) levels. The EcoQS based on benthic foraminiferal diversity reflects a similar trend to the EcoQS based on contaminant concentrations. Foraminiferal density and diversity is low throughout the harbor with distinct assemblages reflecting influence of physical disturbances or chemical stressors. Assemblages impacted by physical disturbance are dominated by L. lobatula and E. excavatum, while assemblages impacted by chemical stressors are dominated by opportunistic species S. fusiformis, S. biformis, B. spathulata and E. excavatum. The foraminiferal assemblage from an un-impacted nearby fjord consists mainly of agglutinated taxa. These assemblages provides a valuable baseline of the ecological impacts of industrialization in northern coastal communities. PMID- 27697321 TI - Biological effects of gold mine tailings on the intertidal marine environment in Nova Scotia, Canada. AB - From 1861 to the 1940s, gold was produced from 64 mining districts in Nova Scotia, where mercury amalgamation was the dominant method for the extraction of gold from ore until the 1880s. As a result, wastes (tailings) from the milling process were contaminated by mercury and were high in naturally occurring arsenic. In 2004 and 2005, sediments, water and mollusc tissues were collected from 29 sampling stations at nine former gold mining areas along the Atlantic coastline and were analysed for arsenic and mercury. The resulting data were compared with environmental quality guidelines. Samples indicated high potential risk of adverse effects in the intertidal environments of Seal Harbour, Wine Harbour and Harrigan Cove. Arsenic in Seal Harbour was bioavailable, resulting in high concentrations of arsenic in soft-shell clam tissues. Mercury concentrations in tissues were below guidelines. This paper presents results of the sampling programs and implications of these findings. PMID- 27697322 TI - Capability of Paraguacu estuary (Todos os Santos Bay, Brazil) to form oil-SPM aggregates (OSA) and their ecotoxicological effects on pelagic and benthic organisms. AB - For experiments concerning the formation of oil-suspended particulate matter (SPM) aggregates (OSA), oil and sediment samples were collected from Campos Basin and six stations of Paraguacu estuary, Todos os Santos Bay, Brazil, respectively. The sediments samples were analyzed for organic matter determined by the EMBRAPA method, nitrogen determined by the Kjeldahl method, and phosphorus determined by the method described by Aspila. The oil trapped in OSA was extracted following the method described by Moreira. The experiment showed a relationship between the amount of organic matter and OSA formation and consequently the dispersion of the studied oil. On the basis of the buoyancy of OSA and the ecotoxicological effects on pelagic and benthic community, the priority areas for application of remediation techniques are Cachoeira, Maragogipe, and Salinas da Margarida because of the large amount of oil that accumulated at the bottom of the experiment flask (5.85%, 27.95%, and 38,98%; 4.2%, 17.66%, and 32.64%; and 11.82%, 8.07%, and 10.91% respectively).

AB - OBJECTIVE: To test whether the reported association between pediatric epilepsy and behavioral problems may be distorted by the use of parental proxy report instruments. STUDY DESIGN: Children in the Connecticut Study of Epilepsy were assessed 8-9 years after their epilepsy diagnosis (time-1) with the parent-proxy Child Behavior Check List (CBCL) (ages 6-18 years) or the Young Adult Self-Report (>=18 years of age). For children <18 years of age, parents also completed the Child Health Questionnaire, which contains scales for impact of child's illness on the parents. The same study subjects completed the Adult Self-Report 6-8 years later (time-2). Sibling controls were also tested. Case-control differences were examined for evidence suggesting more behavioral problems in cases with epilepsy than in controls based on proxy- vs self-report measures. RESULTS: At time-1, parent-proxy CBCL scores were significantly higher (worse) for cases than controls (n = 140 matched pairs). After adjustment for Child Health Questionnaire scales reflecting parent emotional and time impact, only 1 case-control difference on the CBCL remained significant. Self-reported Young Adult Self Report scores did not differ between cases and controls (n = 42 pairs). At time 2, there were no significant self-reported case-control differences on the Adult Self-Report (n = 105 pairs). CONCLUSIONS: Parent-proxy behavior measures appear to be influenced by the emotional impact of epilepsy on parents. This may contribute to apparent associations between behavioral problems and childhood epilepsy. Self-report measures in older adolescents (>18 years of age) and young adults do not confirm parental perceptions. Evidence suggesting more behavioral problems in children with epilepsy should be interpreted in light of the source of information.

PMID- 27697327 TI - The Benefit of Sleeve Gastrectomy in Obese Adolescents on Nonalcoholic Steatohepatitis and Hepatic Fibrosis. AB - OBJECTIVE: To determine whether bariatric surgery is effective for the treatment of nonalcoholic steatohepatitis (NASH) in adolescence, we compared the efficacy of laparoscopic sleeve gastrectomy (LSG) with that of lifestyle intervention (nonsurgical weight loss [NSWL]) for NASH reversal in obese adolescents. STUDY DESIGN: Obese (body mass index >= 35 kg/m2) adolescents (13-17 years of age) with biopsy-proven NAFLD underwent LSG, lifestyle intervention plus intragastric weight loss devices (IGWLD), or only NSWL. At baseline and 1 year after treatment, patients underwent clinical and psychosocial evaluation, blood tests, liver biopsy, polysomnography, and 24-hour ambulatory blood pressure estimation. RESULTS: Twenty patients (21%) underwent LSG, 20 (21%) underwent IGWLD, and 53 (58%) received lifestyle intervention alone (NSWL). One year after treatment, patients who underwent LSG lost 21.5% of their baseline body weight, whereas patients who underwent IGWLD lost 3.4%, and patients who underwent NSWL increase 1.7%. In patients who underwent LSG, NASH reverted completely in all patients and hepatic fibrosis stage 2 disappeared in 18 patients (90%). After IGWLD, NASH reverted in 6 patients (24%) and fibrosis in 7 (37%). Patients who received the NSWL intervention did not improve significantly. Hypertension resolved in all patients who underwent LSG with preoperative hypertension (12/12) versus 50% (4/8) of the patients who underwent IGWLD (P = .02). The cohort-specific changes in impaired glucose metabolism were similar: 100% (9/9) of affected patients who underwent LSG versus 50% (1/2) of patients who underwent IGWLD (P = .02). LSG was also more affective in resolving dyslipidemia (55% [7/12] vs 26% [10/19]; P = .05) and sleep apnea (78% [2/9] vs 30% [11/20]; P = .001). CONCLUSION: LSG was more effective than lifestyle intervention, even when combined with intragastric devices, for reducing NASH and liver fibrosis in obese adolescents after 1 year of treatment.

PMID- 27697330 TI - Effect of Nutritional Supplementation on Growth in Short and Lean Prepubertal Children after 1 Year of Intervention. AB - OBJECTIVE: To determine the 1-year effectiveness and safety of nutritional supplementation with the study formula on linear growth and weight gain in short and lean prepubertal children and to validate the previously reported findings in those initially treated with placebo. STUDY DESIGN: Two-phase 1-year intervention (double-blind placebo-controlled [0-6 months] and open-labeled extension [6-12 months]) in which all participants were offered to continue the study using the study formula. Anthropometric measures and 3-day food diary were assessed at baseline and after 6 and 12 months of intervention. RESULTS: A total of 129 out of 150 children (86%) completed the open-labeled extension-phase. In "good" consumers of the formula (intake >=50% of recommended dose) throughout the entire year height-SDS continued to improve in the extension phase, with a total gain of 0.19 +/- 0.14 SD. In "good" consumers of the formula initially randomized to the placebo-group, the gain in height-SDS significantly improved (from 0.04 +/- 0.13 to 0.12 +/- 0.11; P = .001), replicating the results of the "good" consumers of the formula during the blinded-phase (0.12 +/- 0.12). "Poor" consumers (intake <50% of recommended dose) did not improve their height-SDS. No significant changes in body mass index SDS were observed with the consumption of the formula. A dose-response was found between the amount of formula consumed/kg and the increment in height-SDS and weight-SDS (r = 0.36; P < .001 and r = 0.18; P = .041, respectively). No serious adverse events were reported. CONCLUSIONS: One year of a nutritional supplement was effective in promoting the linear growth of short and lean prepubertal children, with no change in body mass index status.

AB - OBJECTIVES: To compare rates of typmanostomy tube insertions for otitis media with effusion with estimates of need in 2 countries. STUDY DESIGN: This cross sectional analysis used all-payer claims to calculate rates of tympanostomy tube insertions for insured children ages 2-8 years (2007-2010) across pediatric surgical areas (PSA) for Northern New England (NNE; Maine, Vermont, and New Hampshire) and the English National Health Service Primary Care Trusts (PCT). Rates were compared with expected rates estimated using a Monte Carlo simulation model that integrates clinical guidelines and published probabilities of the incidence and course of otitis media with effusion. RESULTS: Observed rates of tympanostomy tube placement varied >30-fold across English PCT (N = 150) and >3 fold across NNE PSA (N = 30). At a 25 dB hearing threshold, the overall difference in observed to expected tympanostomy tubes provided was -3.41 per 1000 child-years in England and -0.01 per 1000 child-years in NNE. Observed incidence of insertion was less than expected in 143 of 151 PCT, and was higher than expected in one-half of the PSA. Using a 20 dB hearing threshold, there were fewer tube insertions than expected in all but 2 England and 7 NNE areas. There was an inverse relationship between estimated need and observed tube insertion rates. CONCLUSIONS: Regional variations in observed tympanostomy tube insertion rates are unlikely to be due to differences in need and suggest overall underuse in England and both overuse and underuse in NNE. PMID- 27697332 TI - Strength, toughness and aging stability of highly-translucent Y-TZP ceramics for dental restorations. AB - OBJECTIVE: The aim was to evaluate the optical properties, mechanical properties and aging stability of yttria-stabilized zirconia with different compositions, highlighting the influence of the alumina addition, Y2O3 content and La2O3 doping on the translucency. METHODS: Five different Y-TZP zirconia powders (3 commercially available and 2 experimentally modified) were sintered under the same conditions and characterized by X-ray diffraction with Rietveld analysis and scanning electron microscopy (SEM). Translucency (n=6/group) was measured with a color meter, allowing to calculate the translucency parameter (TP) and the contrast ratio (CR). Mechanical properties were appraised with four-point bending strength (n=10), single edge V-notched beam (SEVNB) fracture toughness (n=8) and Vickers hardness (n=10). The aging stability was evaluated by measuring the tetragonal to monoclinic transformation (n=3) after accelerated hydrothermal aging in steam at 134 degrees C, and the transformation curves were fitted by the Mehl-Avrami-Johnson (MAJ) equation. Data were analyzed by one-way ANOVA, followed by Tukey's HSD test (alpha=0.05). RESULTS: Lowering the alumina content below 0.25wt.% avoided the formation of alumina particles and therefore increased the translucency of 3Y-TZP ceramics, but the hydrothermal aging stability was reduced. A higher yttria content (5mol%) introduced about 50% cubic zirconia phase and gave rise to the most translucent and aging-resistant Y-TZP ceramics, but the fracture toughness and strength were considerably sacrificed. 0.2mol% La2O3 doping of 3Y-TZP tailored the grain boundary chemistry and significantly improved the aging resistance and translucency. Although the translucency improvement by La2O3 doping was less effective than for introducing a substantial amount of cubic zirconia, this strategy was able to maintain the mechanical properties of typical 3Y-TZP ceramics. SIGNIFICANCE: Three different approaches were compared to improve the translucency of 3Y-TZP ceramics. PMID- 27697333 TI - Lifetime prediction of zirconia and metal ceramic crowns loaded on marginal ridges. AB - OBJECTIVE: To evaluate the fatigue life of zirconia-veneered and metal-ceramic crowns comprised by an even thickness or a modified framework design when loaded on marginal ridges. METHODS: Eighty marginal ridges were present after fabrication of forty molar crowns cemented onto composite-resin replicas and divided (n=20/each), in the following groups: metal-ceramic with even thickness (MCev) or with a modified framework design (MCm, lingual collar with proximal struts); porcelain-fused to zirconia with even thickness (PFZev) or with the modified framework design (PFZm). Each marginal ridge (mesial and distal) was subjected to cyclic loading separately with a lithium disilicate indenter for 106 cycles or until fracture. Kruskal-Wallis and Wilcoxon matched pair test (p<0.05) evaluated both marginal ridges. Every 125,000 cycles, the test was interrupted for damage inspection. Weibull distribution (90% confidence bounds) determined the probability of survival (reliability). RESULTS: Weibull 2-parameter contour plot showed significantly higher fatigue life for PFZev compared to MC, and comparable with PFZm. A significant decrease in reliability was observed between groups from 625,000 until 106 cycles. Metal-ceramic groups presented significantly lower probability of survival at 106 cycles (MCev=0.66% and MCm=4.73%) compared to PFZm (23.41%) and PFZev (36.68%). Fractographic marks showed a consistent fracture origin and direction of crack propagation. Reliability was higher for porcelain-fused to zirconia than for metal ceramic crowns, regardless of framework design. SIGNIFICANCE: Zirconia-veneered crowns presented decreased fracture rates compared to metal ceramics, even when loaded at marginal ridges, regardless of framework design.

Cost-effective, low-cost options for simulation based education can be developed and shared in order to optimize the neonatal simulation training experience. PMID- 27697337 TI - Iron isotope fingerprints of redox and biogeochemical cycling in the soil-water rice plant system of a paddy field. AB - The iron isotope composition was used to investigate dissimilatory iron reduction (DIR) processes in an iron-rich waterlogged paddy soil, the iron uptake strategies of plants and its translocation in the different parts of the rice plant along its growth. Fe concentration and isotope composition (delta56Fe) in irrigation water, precipitates from irrigation water, soil, pore water solution at different depths under the surface water, iron plaque on rice roots, rice roots, stems, leaves and grains were measured. Over the 8.5-10cm of the vertical profiles investigated, the iron pore water concentration (0.01 to 24.3mg.l-1) and delta56Fe (-0.80 to -3.400/00) varied over a large range. The significant linear co-variation between Ln[Fe] and delta56Fe suggests an apparent Rayleigh-type behavior of the DIR processes. An average net fractionation factor between the pore water and the soil substrate of Delta56Fe~-1.150/00 was obtained, taking the average of all the delta56Fe values weighted by the amount of Fe for each sample. These results provide a robust field study confirmation of the conceptual model of Crosby et al. (2005, 2007) for interpreting the iron isotope fractionation observed during DIR, established from a series of laboratories experiments. In addition, the strong enrichment of heavy Fe isotope measured in the root relative to the soil solution suggest that the iron uptake by roots is more likely supplied by iron from plaque and not from the plant-available iron in the pore water. Opposite to what was previously observed for plants following strategy II for iron uptake from soils, an iron isotope fractionation factor of -0.90/00 was found from the roots to the rice grains, pointing to isotope fractionation during rice plant growth. All these features highlight the insights iron isotope composition provides into the biogeochemical Fe cycling in the soil-water-rice plant systems studied in nature. PMID- 27697338 TI - Trace element concentrations, risks and their correlation with metallothionein genes polymorphism: A case study of narrow-ridged finless porpoises (Neophocaena asiaeorientalis) in the East China Sea. AB - The concentration of trace elements (TEs) and their risk to narrow-ridged finless porpoises (Neophocaena asiaeorientalis) are still unclear. The present study determined the concentration of typical TEs in liver, kidney, and muscle tissues from porpoises in the East China Sea, assessed potential health risk of TEs to porpoises, and explored the relationship between TE concentration and metallothionein genes (MTs) polymorphism. It was found that Zn, Cu, Mn, Cd and Hg were highly accumulated in liver, and Cd was highly accumulated in kidney. The concentrations of Cr, As, Pb and Ni were very low in all three tissues. TE concentrations showed significant positive correlation with body length, and sexual variation. The levels of most TEs were higher in tissues of porpoises in Ningbo and Nantong than in Pingtan, which is likely related to the local environment pollution level. The risk assessment showed that porpoises from Nantong and Ningbo could face health risks due to Hg, As, Cd, Pb, and Cr exposure. Moreover, two polymorphic sites on the MT4 gene were found to be significantly associated with increased levels of Hg, Cd, Zn and Mn. Whether these two polymorphic sites are involved in expression of MTs, or other functional processes, needs further research. PMID- 27697339 TI - Linking current river pollution to historical pesticide use: Insights for territorial management? AB - Persistent organic pollutants like organochlorine pesticides continue to contaminate large areas worldwide raising questions concerning their management. We designed and tested a method to link soil and water pollution in the watershed of the Galion River in Martinique. We first estimated the risk of soil contamination by chlordecone by referring to past use of land for banana cultivation and took 27 soil samples. We then sampled surface waters at 39 points and groundwater at 16 points. We tested three hypotheses linked to the source of chlordecone pollution at the watershed scale: (i) soils close to the river, (ii) soils close to the sampling point, (iii) throughout the sub-watershed generated at the sampling point. Graphical and statistical analysis showed that contamination of the river increased when it passed through an area with contaminated plots and decreased when it passed through area not contaminated by chlordecone. Modeling showed that the entire surface area of the watershed contributed to river pollution, suggesting that the river was mainly being contaminated by the aquifers and groundwater flows. Our method proved to be a reliable way to identify areas polluted by chlordecone at the watershed scale and should help stakeholders focus their management actions on both hot spots and the whole watershed.

AB - : Time trends and spatial patterns for wet nitrogen deposition in view of its reduced and oxidized forms for Czech forests are presented. Time trends in NH4+, NO3-, and N-NH4+/N-NO3- ratio at 15 sites in 1990-2014 were analysed using the Mann-Kendal test. Changes in spatial patterns derived from results of 43 sites in 2005-2014 were also assessed. Our results indicated a slow but convincing change in favour of NH4+. The N-NH4+/N-NO3- ratio, both in precipitation and wet deposition, has been increasing steadily, reflecting the changes in reduced and oxidized forms of nitrogen emissions. A similar change has been observed in some other regions and might have negative impacts on ecosystems. CAPSULE: N-NH4+/N NO3- ratio in precipitation and deposition changes in favour of NH4+. This reflects changes in emissions and might have implications for ecosystems. PMID- 27697341 TI - Transfer, tissue distribution and bioaccumulation of microcystin LR in the phytoplanktivorous and carnivorous fish in Anzali wetland, with potential health risks to humans. AB - This study was conducted to determine Microcystin LR concentration in the aquatic ecosystem of the Anzali wetland in Iran. Extraction and detection of MC-LR from the water and fish samples was conducted by the SPE and HPLC-UV apparatus. Our results showed that among toxic cyanobacteria, Anabaena was the dominant genera during the study period. The results indicated that MC-LR content in water ranged from 0.18 to 3.02MUg/L in dissolved fraction and undetectable level to 1.13MUg/L in cellular fraction, in all three seasons. The results of PCA revealed that the environmental parameters including EC, Chl-a, PO43-, pH and temperature were the most effective factors influencing the MC-LR production. Results further showed the mean concentration of MC-LR in muscle and liver of silver carp ranged from 10.12 to 40.98 and from undetectable to 44.34MUg/kg w.w, respectively. The mean concentration of MC-LR in northern pike was 15.18 to 35.1MUg/kg w.w in muscle and undetectable to 51.91MUg/kg w.w in liver samples. Our results suggest that consumption of fish harvested from the Anzali wetland seems to be unsafe for humans, based on obtained estimated daily intake values which were higher than the tolerable daily intake value recommended by WHO. In addition, bioaccumulation factor of MC-LR in edible tissues of fish was estimated based on lipid normalization. The results showed that the BAF of MC-LR in silver carp (1047+/ 185L/kg of lipid) was lower than the northern pike (1272+/-185L/kg of lipid), although the difference was not significant. PMID- 27697342 TI - Urbanization-related changes in soil PAHs and potential health risks of emission sources in a township in Southern Jiangsu, China. AB - Urbanization, which is characterized by population aggregation, industrial development, and increased traffic load, may change local polycyclic aromatic hydrocarbons (PAH) emissions and their associated health risks. To investigate these changes, we collected soil samples in 2009 and 2014 in a rapidly developing small town in Southern Jiangsu (China) and measured the concentrations of 16 PAHs via gas chromatography-mass spectrometry. Although the total PAHs decreased from 4586.6 to 640.6ng/g, the concentrations of the high-molecular-weight PAHs benzo(b)fluoranthene and benzo(a)pyrene increased due to changes in the PAH sources. Source apportionment by positive matrix factorization indicated that the two sources responsible for the highest soil PAH contributions changed from biomass combustion (42%) and coal combustion (32%) in 2009 to coal, biomass and natural gas combustion (35%) and diesel combustion (33%) in 2014. However, the two sources with the highest associated health risks were diesel and gasoline combustion in both years. The incremental lifetime cancer risk for residents exposed to PAHs in the soil via incidental ingestion and dermal contact decreased from 1.75*10-6 to 1.60*10-6. The ban on open burning of straw and the substitution of coal with natural gas offset the PAH health risks due to increased urbanization. PMID- 27697344 TI - Sources and mass inventory of sedimentary polycyclic aromatic hydrocarbons in the Gulf of Thailand: Implications for pathways and energy structure in SE Asia. AB - Surface sediments obtained from a matrix of 92 sample sites in the Gulf of Thailand (GOT) were analyzed for a comprehensive study of the distribution, sources, and mass inventory of polycyclic aromatic hydrocarbons (PAHs) to assess their input pathways and impacts of the regional land-based energy structure on the deposition of PAHs on the adjacent continental margins. The concentration of 16 PAHs in the GOT ranged from 2.6 to 78.1ng/g (dry weight), and the mean concentration was 19.4+/-15.1ng/g. The spatial distribution pattern of 16 PAH was generally consistent with that of sediment grain size, suggesting the influence of regional hydrodynamic conditions. Correlation and principal component analysis of the PAHs indicated that direct land-based inputs were dominantly responsible for the occurrence of PAHs in the upper GOT and the low molecular weight (LMW) PAHs in the coastal region could be from petrogenic sources. A positive matrix factorization (PMF) model apportioned five contributors: petroleum residues (~44%), biomass burning (~13%), vehicular emissions (~11%), coal combustion (~6%), and air-water exchange (~25%). Gas absorption may be a significant external input pathway for the volatile PAHs in the open GOT, which further implies that atmospheric loading could be important for the sink of PAHs in the open sea of the Southeast Asia (SE Asia). The different PAH source patterns obtained and a significant disparity of PAH mass inventory in the sediments along the East and Southeast Asia continental margins can be ascribed mainly to different land-based PAH emission features under the varied regional energy structure in addition to the depositional environment and climatic conditions. PMID- 27697343 TI - Occurrence, profile and spatial distribution of organochlorines pesticides in soil of Nepal: Implication for source apportionment and health risk assessment. AB - Nepal is a landlocked country located between world's two most populous countries India and China where high level of organochlorines pesticides has been reported from multi-environmental matrices. In this study, we investigated the occurrence, distributions and profile of selected OCP chemicals in surface soil samples (N=72) from four major cities of Nepal. Overall, the sum of total OCPs in soil ranged from 20 to 250ng/g with Biratnagar being the most polluted site in Nepal. DDTs and endosulfans were the most abundant OCP chemicals in soil samples. The concentration of DDTs ranged from 8 to 230ng/g, 8-56ng/g, 8-63ng/g, and 8-27ng/g in surface soil, while endosulfans were in the range of 2.9-3.3ng/g, 2.8-8.7ng/g, 2.8-3.4ng/g, 2.8-3.2ng/g in Biratnagar, Kathmandu, Pokhara and Birgunj, respectively. The isomeric ratio of DDT and their metabolites suggested the ongoing usages of technical DDT as well as dicofol in this region. Lower ratio of alpha/beta-endosulfan indicated past application of endosulfans in Nepal. HCHs were less detected OCPs in soil sample accounting only 4-9% of ?OCPs. The isomeric ratio of alpha-/gamma-HCH indicated that the HCHs may be originated from mixed source of technical HCH as well as lindane use. Scattered plot of TOC and BC showed they were weakly and positively related with concentration of OCPs in soil. Health risk assessment modeling study of OCPs in soil suggested moderate cancer risk with ingestion being the most potential pathway of OCPs exposure. PMID- 27697345 TI - Investigation of chlorinated solvent pollution with resistivity and induced polarization. AB - Globally, an enormous number of polluted areas are in need of remediation to prevent adverse effects on health and environment. In situ remediation and especially the monitoring thereof needs further development to avoid costly and hazardous shipments associated with excavation. The monitoring of in situ remediation actions needs easier and cheaper nondestructive methods for evaluation and verification of remediation degree and degradation status of the contaminants. We investigate the Direct Current resistivity and time-domain Induced Polarization tomography (DCIP) method and its use within the context of a DNAPL (Dense Non-Aqueous Phase Liquids) contaminated site in Varberg, Sweden, where an in situ remediation pilot test has been performed by stimulated reductive dechlorination by push injection. Our results show that the DCIP technique is an emerging and promising technique for mapping of underground structures and possibly biogeochemical spatial and temporal changes. The methodology could in combination with drilling, sampling and other complementary methods give an almost continuous image of the underground structures and delineation of the pollutant situation. It can be expected to have a future in monitoring approaches measuring time lapse induced polarization (IP), if more research is performed on the parameters and processes affecting the IP-signals verifying the interpretations. The IP technique can possibly be used for verification of the effectiveness of in situ remediation actions, as the current sampling methodology is inadequate.

AB - As a fragile ecological zone, the temperate grassland region of China has experienced dramatic land use/land cover (LULC) changes due to human disturbances. So far, the impacts of LULC change on climate especially the diurnal temperature range (DTR) in this region are still not well understood. Based on the OMR (observation minus reanalysis) method, this study investigated the effects of LULC on DTR in the temperate grassland region of China. Considering the possible uncertainty of the results due to spatial resolution of the reanalysis dataset, two reanalysis datasets with different spatial resolutions were utilized. Results showed that LULC generally contributed to the decline of DTR in the temperate grassland region of China during 1980 to 2005. Due to different warming effects on monthly maximum temperature (Tmax) and minimum temperature (Tmin), grassland and forest tend to slightly decrease monthly DTR (approximately -0.053 to -0.050 degrees C/decade and approximately 0.059 to -0.055 degrees C/decade, respectively), while bare land has a slightly positive effect on DTR (approximately 0.018-0.021 degrees C/decade). By contrast, cropland and urban tend to slightly decrease Tmax, obviously increase Tmin and thus result in a rapid decline of DTR (approximately -0.556 to -0.503 degrees C/decade and approximately -0.617 to -0.612 degrees C/decade, respectively). In the temperate grassland region of China, grassland vegetation changes due to human disturbances can have some effects on DTR mainly by changing the Tmax. Conversion from grassland to cropland could decrease the DTR by slowing down the increase of Tmax. But the conversion from grassland to bare land, as well as the reduction of grassland vegetation cover will increase Tmax, and consequently the DTR. The results suggest that grassland degradation is likely to result in daylight warming and increased DTR in the temperate grassland region of China. PMID- 27697347 TI - Arbuscular mycorrhizal fungal assemblages in biological crusts from a Neotropical savanna are not related to the dominant perennial Trachypogon. AB - Knowledge of the arbuscular mycorrhizal fungal assemblages in the Trachypogon savanna ecosystems is very important to a better understanding of the ecological processes mediated by this soil microbial group that affects multiple ecosystem functions. Considering the hypothesis that the biocrusts can be linked to vegetation through the arbuscular fungi mycelial network, the objectives proposed in this study were to determine (i) whether there are arbuscular mycorrhizal fungi (AMF) in the biocrusts (ii) whether arbuscular mycorrhizal fungal assemblages are linked to the Trachypogon patches, and (iii) whether the composition of the assemblages is related to soil properties affected by microbiological activity. The community structure of the AMF was investigated in three habitats: rhizospheric soil and roots of Trachypogon vestitus, biological soil crusts, and bare soil. The canonical correspondence analysis showed that two soil properties related to enzymatic activity (protease and beta-glucosidase) significantly affected the community composition of the AMF. The biocrusts in the Venezuelan savanna are colonized by an AM fungal community linked to that of the bare soil and significantly different from that hosted by the roots of the surrounding T. vestitus, suggesting that assemblages of AMF in biocrusts might be related more closely to those of annual plant species appearing in favorable conditions. PMID- 27697348 TI - Towards a better pesticide policy for the European Union. AB - This opinion article aims to foster the debate about pesticide legislation in the European Union (EU). Numerous formerly authorized and widely used pesticides are now banned in the EU because unexpected and unacceptable risks emerged after their initial introduction to the market. Throughout this time lapse, environmental quality and human health have been threatened by the use of these compounds. These hazards could have been prevented by a more responsive pesticide regulatory framework. This article provides detailed insights into the pros and cons of pesticides, and points out weaknesses of the current pesticide environmental risk assessment procedures. Possibilities for improving the robustness and reliability of the pesticide regulatory framework are discussed. PMID- 27697349 TI - Sustainable use of veterinary pharmaceuticals on the territory (Sust-PHarm): Linking available database of manure management and environmental fate models. AB - Analogously to the evolution of the EU legislation on pesticides, there is an increasing need of strategies aiming to reach a "sustainable use of veterinary pharmaceuticals". To this end, it is essential to develop tools, such as supporting information systems (SIS), for managing the environmental risks of veterinary pharmaceuticals on a territorial scale. In this context, we propose Sust-PHarm (SUSTainable use of veterinary Pharmaceuticals), a SIS useful to identify groundwater vulnerable areas to veterinary pharmaceuticals at both local and regional scale. As background, Sust-PHarm follows the schemes of SIS for pesticides. The latter are based on the integration of predictive models in GIS. The proposed approach goes a step forward by integrating also data on the typologies of livestock farm, their spatial distribution and manure management techniques. This information allows to identify the potential environmental loads of veterinary pharmaceuticals. In this paper, we discuss the innovative elements characterizing Sust-PHarm through a comparison with the SIS currently used for pesticides. The advantages of Sust-PHarm are discussed using Lombardia Region (Northern Italy) as a case study. Simulations were made on 12 veterinary pharmaceuticals characterized by different physical-chemical properties. Results are compared with the current guidelines for the evaluation of veterinary pharmaceuticals leaching highlighting some substantial differences when realistic data are utilized making our approach more accurate than guidelines one. PMID- 27697350 TI - The influence of the autochthonous wastewater microbiota and gene host on the fate of invasive antibiotic resistance genes. AB - The aim of this study was to assess the fate of invasive antibiotic resistance genes (ARG) discharged in wastewater. With this objective, antibiotic resistant bacteria (ARB) known to harbor specific ARG were inoculated in wastewater (hospital effluent, or municipal raw and treated wastewater) and in ultra-pure sterile water microcosms. Two sets of wastewater ARB isolates were used - set 1, Enterococcus faecalis, Acinetobacter johnsonii, Klebsiella pneumoniae and set 2, Enterococcus faecium, Acinetobacter johnsonii, Escherichia coli. Non-inoculated controls were run in parallel. Samples were collected at the beginning and at the end (15days) of the incubation period and the abundance of the genes 16S rRNA, intI1, blaTEM and vanA and the bacterial community composition were analyzed. In general, the genes blaTEM and vanA had lower persistence in wastewater and in ultra-pure water than the genes 16S rRNA or the class 1 integron integrase intI1. This effect was more pronounced in wastewater than in ultra-pure water, evidencing the importance of the autochthonous microbiota on the elimination of invasive ARG. Wastewater autochthonous bacterial groups most correlated with variations of the genes intI1, blaTEM and vanA were members of the classes Gammaproteobacteria, Bacilli or Bacteroidia. For blaTEM, but not for vanA, the species of the ARB host was important to determine its fate. These are novel findings on the ecology of ARB in wastewater environments. PMID- 27697351 TI - Effect of water quality improvement on the remediation of river sediment due to the addition of calcium nitrate. AB - In situ sediment remediation technique is commonly used to control the release of pollutants from sediment. Addition of calcium nitrate to sediment has been applied to control the release of phosphorus from sediments. In this study, laboratory experiments were conducted to investigate the effect of water quality improvement on the remediation of river sediment with the addition of calcium nitrate. The results demonstrated that the redox-potential of sediments increased from -282mV to -130mV after 28days of calcium nitrate treatment. The acid volatile sulphide in the sediments significantly decreased (by 54.9% to 57.1%), whereas the total organic carbon decreased by 9.7% to 10.2%. However, the difference between these and water quality improvement was not significant. Due to the addition of calcium nitrate, low phosphate concentration in the water column and interstitial phosphate in the sediment were observed, indicating that the calcium nitrate was beneficial to controlling the release of phosphorus from river sediment. The decrease in phosphorus release could be attributed to the fixation of iron-phosphorus and calcium-phosphorus due to the addition of calcium nitrate. The addition of calcium nitrate to sediment caused the oxidation of sulphide to sulphate, hence resulting in high nitrate and sulphate concentrations in the water column, and high interstitial nitrate and sulphate concentrations in the sediment. The results also showed that only the water quality improvement had a significant effect on the interstitial nitrate and sulphate concentrations in the sediment.

PMID- 27697354 TI - [Comparison of transforaminal and interlaminar epidural steroid injections for the treatment of chronic lumbar pain]. AB - STUDY DESIGN: A cross-sectional study. OBJECTIVE: We compared the 12 month outcomes of fluoroscopically guided transforaminal epidural steroid injections with interlaminar epidural steroid injections for the treatment of chronic lumbar spinal pain. Chronic lower back pain is a multifactorial disorder with many possible etiologies. The lifetime prevalence of spinal pain is reportedly 65-80% in the neck and lower back. Epidural injection of corticosteroids is a commonly used intervention for managing chronic spinal pain. METHODS: Patients who did not benefit from previous treatments were included in this study. Injections were performed according to magnetic resonance imaging findings at the nearest level of lumbar pathology; 173 patients received interlaminar epidural steroid injections and 126 patients received transforaminal epidural steroid injections. All of the patients were regularly followed up for 12 months using a verbal numeric rating scale. Magnetic resonance imaging findings, complications, verbal numeric rating scale, and satisfaction scores were recorded. RESULTS: Lumbar disk pathology was the most frequently encountered problem. The interlaminar epidural steroid injections were preferred at the L4-L5 intervertebral level. Verbal numeric rating scale scores significantly decreased during the 12-month period compared to basal scores (p<0.001). Significant differences between the two groups according to verbal numeric rating scale and satisfaction scores were not observed (p>0.05). There were no major complications; however, the interlaminar epidural steroid injections group had 22 (12.7%) minor complications, and the transforaminal epidural steroid injections group had 12 (9.5%) minor complications. CONCLUSIONS: This study showed that interlaminar epidural steroid injections can be as effective as transforaminal epidural steroid injections when performed at the nearest level of lumbar pathology using fluoroscopy in 12-month intervals. PMID- 27697356 TI - Changing body temperature during aortic arch surgery. PMID- 27697357 TI - Right internal thoracic artery or radial artery? A propensity-matched comparison on the second-best arterial conduit. AB - OBJECTIVES: We conducted propensity score matching to determine whether the use of the right internal thoracic artery (RITA) confers a survival advantage when compared with the radial artery (RA) as second arterial conduit in coronary artery bypass grafting. METHODS: The study population included a highly selected low-risk group of patients who received the RITA (n = 764) or the RA (n = 1990) as second arterial conduit. We obtained 764 matched pairs that were comparable for all pretreatment variables. A time-segmented Cox regression model that stratified on the matched pairs was used to investigate the effect of treatment on late mortality. RESULTS: After a mean follow-up of 10.2 +/- 4.5 years (maximum 17.3 years), survival probabilities at 5, 10, and 15 years were 96.4% +/- 0.7% versus 95.4% +/- 0.7%, 91.0% +/- 1.1% versus 89.1% +/- 1.2%, and 82.4% +/- 1.9% versus 77.2% +/- 2.5% in the RITA and RA groups, respectively. During the first 4 years, RITA and RA were comparable in terms of mortality (hazard ratio [HR], 1.00; 95% confidence interval [CI], 0.56-1.78; P = .98). However, after 4 years RITA was associated with a significant reduction in late mortality (HR, 0.67; 95% CI, 0.48-0.95; P = .02). RITA was superior to RA when the experimental conduit was used to graft the left coronary system (HR, 0.69; 95% CI, 0.47-0.99; P = .04) but not the right coronary system (HR, 0.98; 95% CI, 0.59-1.62; P = .93). CONCLUSIONS: In a highly selected low-risk group of patients, the use of the RITA as second arterial conduit instead of the RA was associated with better survival when used to graft the left but not the right coronary artery.

PMID- 27697359 TI - Mast cell activation and arterial hypotension during proximal aortic repair requiring hypothermic circulatory arrest. AB - OBJECTIVE: Aortic surgeries requiring hypothermic circulatory arrest evoke systemic inflammatory responses that often manifest as vasoplegia and hypotension. Because mast cells can rapidly release vasoactive and proinflammatory effectors, we investigated their role in intraoperative hypotension. METHODS: We studied 31 patients undergoing proximal aortic repair with hypothermic circulatory arrest between June 2013 and April 2015 at Duke University Medical Center. Plasma samples were obtained at different intraoperative time points to quantify chymase, interleukin-6, interleukin-8, tumor necrosis factor alpha, and white blood cell CD11b expression. Hypotension was defined as the area (minutes * millimeters mercury) below a mean arterial pressure of 55 mm Hg. Biomarker responses and their association with intraoperative hypotension were analyzed by 2-sample t test and Wilcoxon rank sum test. Multivariable logistic regression analysis was used to examine the association between clinical variables and elevated chymase levels. RESULTS: Mast cell-specific chymase increased from a median 0.97 pg/mg (interquartile range [IQR], 0.01-1.84 pg/mg) plasma protein at baseline to 5.74 pg/mg (IQR, 2.91-9.48 pg/mg) plasma protein after instituting cardiopulmonary bypass, 6.16 pg/mg (IQR, 3.60-9.41 pg/mg) plasma protein after completing circulatory arrest, and 7.64 pg/mg (IQR, 4.63-12.71 pg/mg) plasma protein after weaning from cardiopulmonary bypass (each P value < .0001 vs baseline). Chymase was the only biomarker associated with hypotension during (P = .0255) and after (P = .0221) cardiopulmonary bypass. Increased temperatures at circulatory arrest and low presurgical hemoglobin levels were independent predictors of increased chymase responses. CONCLUSIONS: Mast cell activation occurs in cardiac surgery requiring cardiopulmonary bypass and hypothermic circulatory arrest and is associated with intraoperative hypotension. PMID- 27697360 TI - Mid-term durability of the Trifecta bioprosthesis for aortic valve replacement. AB - OBJECTIVE: To clarify the mid-term durability of the Trifecta bioprosthesis for aortic valve replacement (AVR). METHODS: We retrospectively analyzed the prospectively collected data of 824 consecutive implants of the Trifecta valve at a single institution. A 100% complete follow-up was available (average duration, 2.2 +/- 1.3 years; range, 0.03-6.9 years; 1747.6 patient-years). Echocardiography data at discharge were recorded prospectively. RESULTS: Operative mortality was 3.8%; 2.7% in patients receiving isolated AVR. There were 5 valve-related early reoperations, including 1 for infective prosthetic endocarditis and 4 for nonstructural valve dysfunction. The global rate of severe patient-prosthesis mismatch was 1.26%. Overall 5-year survival was 74.9%, and freedom from valve related death was 97.8%. The majority of deaths attributed to the valve were due to unknown causes. We observed 6 SVD events at 3.4 +/- 1.6 years after surgery. At 5 years, the actuarial freedom from SVD was 98% +/- 0.9% (n = 6), freedom from reintervention for SVD was 98% +/- 0.9% (n = 5, including 2 transcatheter valve in-valve), and freedom from open reoperation for SVD was 98.9% +/- 0.6%. The 5 year freedom from prosthetic endocarditis was 97.7% +/- 0.7% (n = 12, 6 requiring reoperation). There was 1 case of late NSVD (5-year freedom, 99.8% +/- 0.2%). Freedom from hemorrhagic events was 98.6% +/- 0.5% (86% occurring in patients on anticoagulants); there were no thromboembolic events at follow-up. CONCLUSIONS: The Trifecta bioprosthesis is a reliable device for AVR. We confirm excellent immediate hemodynamic properties and a very low rate of patient-prosthesis mismatch. The absolute number of SVD cases observed remains limited; nevertheless, their timing, pathological characteristics, and clinical presentation mandate continued follow-up. PMID- 27697361 TI - Unsuspected Malignancies in Routine Femoral Head Histopathologic Examination During Primary Total Hip Arthroplasty: Cost-Effectiveness Analysis. AB - BACKGROUND: Routine femoral head histopathology during primary total hip arthroplasty (THA) has been recently reported as a potentially useful screening tool for bone- and bone marrow-associated malignancies. However, cost effectiveness of routine histopathology during THA remains unclear due to low prevalence of significant medical findings which alter patient management. The aim of this study was to evaluate the cost-effectiveness of routine histopathology in diagnosing unsuspected malignancy in patients undergoing primary THA. METHODS: From 1993 to 2011, we retrospectively analyzed routine histopathologic findings of 3200 femoral head specimens from 2725 patients that underwent primary THA. Preoperative and postoperative diagnoses were classified into concordant (clinical diagnosis concurred with pathologic diagnosis), discrepant (differing diagnosis with no resultant impact on patient management), and discordant (differing diagnosis with subsequent change in patient management). Cost-effectiveness analysis was performed using the incremental cost utility ratio. RESULTS: A total of 3055 of 3200 pathologic samples were concordant with the preoperative diagnosis (95.4%), 140 of 3200 were discrepant (4.4%), and 5 of 3200 were discordant (0.2%). Routine histopathology revealed 1 unsuspected malignancy out of 640 (5 of 3200) femoral heads. The total cost of histopathologic screening was $614,664.80. The average cost to identify a discrepant case was $4390.46, and the cost to identify a discordant case was $122,932.96. The incremental cost-utility ratio was $49,569.74 per quality adjusted life year (QALY) gained. CONCLUSION: Our study indicates routine femoral head histopathology may be cost-effective in diagnosing unsuspected malignancy at $49,569.74/QALY gained (less than World Health Organization recommended threshold $159,000/QALY gained), providing useful clinical information for surgeons considering the value of routine femoral head histopathology in patients undergoing THA. PMID- 27697362 TI - Collaborative study for the calibration of a replacement International Standard for diphtheria toxoid for use in flocculation test. AB - We present the results of a collaborative study for the establishment of a replacement International Standard (IS) for diphtheria toxoid for use in flocculation test and its calibration in Lf units. Calibration was performed using Ramon flocculation method, standardized using the 2nd IS. The candidate standard was assigned a unitage of 1870 Lf/ampoule based on results from 25 laboratories in 15 different countries and was established as the 3rd IS for diphtheria toxoid for use in flocculation test by the WHO Expert Committee on Biological Standardization (ECBS) in October 2015. The study also assessed the use of alternative methods for measuring Lf. Participants were asked to determine the Lf value of the candidate standard using an Enzyme Linked Immunosorbent Assay (ELISA) established at NIBSC, or other suitable in-house method. 10 laboratories performed ELISA according to the NIBSC protocol, 1 laboratory performed flocculation using laser-light scattering according to an in-house protocol, and 1 laboratory performed another in-house ELISA. Results suggest these methods may provide suitable alternatives to the Ramon flocculation test, subject to validation, and that the new standard could act as a suitable reference preparation in these methods.

AB - Phage therapy is an alternative and eco-friendly biocontrol agent to prevent and control multidrug resistant bacteria in the aquatic system. The aim of this study is to isolate and characterize the Vibrio parahaemolyticus and its potential lytic phage from Penaeus monodon growing-out by rearing in shrimp ponds in Palk Strait, South East coast of India. The conventional phenotypic characteristics and molecular identification was confirmed using 16S rRNA sequence and to determine the antibiotic resistant profiles. The V. parahaemolyticus phage was effective against V. parahaemolyticus through one-step growth experiments, phage survival was determined by long-term storage at various temperatures and pH. Further, transmission electron microscope (TEM) revealed that the lytic phage belongs to the Myoviridae family. The isolated lytic phage (VVP1) was more specific against N1A V. parahaemolyticus and was able to infect N7A V. parahaemolyticus, N3B and N13B Vibrio alginolyticus strains. Evaluation of microcosm studies with P. monodon larvae infected with V. parahaemolyticus showed the survival of larvae in the presence of phage treatment at 2.3 * 1010 PFU/mL-1 was enhanced when compared with the control. This study provides the application of phage as a useful strategy to prevent and eliminate or reduce shrimp pathogenic V. parahaemolyticus in the aquaculture system. PMID- 27697364 TI - DNA damage response regulation by microRNAs as a therapeutic target in cancer. AB - The inability of cancer cells in taking care of DNA damages can lead to cancer development and/or progression. Due to the essential role of DNA repair in maintaining genomic stability, tightly controlled regulatory mechanism are required for these processes. Recent studies have shown a myriad of interactions among DNA damage response (DDR) components and miRNAs. While DDR modulates miRNA expression in transcriptional and post-transcriptional levels and affects miRNA degradation, miRNAs in turn, directly modulate the expression of multiple proteins in the DDR pathways, or indirectly fine-tune the expression of such proteins. A better understanding of DDR-miRNA interactions can facilitate the development of new anticancer agents targeting miRNAs involved in the DNA repair process. In this review, we provide a brief introduction about miRNA biogenesis and functions, DDR pathways, and recent findings about DDR-microRNA interactions. Finally, the therapeutic importance of miRNAs in modulation of DDR/DNA repair mechanisms will be discussed.

PMID- 27697366 TI - High carbohydrate diet induces nonalcoholic steato-hepatitis (NASH) in a desert gerbil. AB - A high intake of sugars has been linked to diet-induced health problems. The aim of this study was to assess whether the long-term consumption of a high carbohydrate diet (HCD) would cause the hepatic histopathological and metabolic abnormalities that characterize nonalcoholic steatohepatitis (NASH) in a desert gerbil, Gerbillus gerbillus. Compared to natural diet, HCD leads to several metabolic disorders including adiposity, dyslipidemia, insulin resistance, ectopic fat deposition in the liver, which were associated with higher levels of transcripts of genes involved with fat synthesis, endoplasmic reticulum (ER) stress, and fibrosis. In the same way, the experimented animals showed enhanced oxidative stress. Taken together, these results demonstrate that HCD consumption in gerbils induces metabolic disorders and damaged liver, which are key contributors to NASH development. These results suggest that this rodent represents a valuable natural model for human diet-induced metabolic disorders and nonalcoholic fatty liver disease (NAFLD). PMID- 27697367 TI - Genetic diversity and population structure of six species of Capparis in Tunisia using AFLP markers. AB - In order to study the genetic diversity, the phylogeographic pattern and hybridization between six Tunisian Capparis species, 213 accessions of Caper were genotyped with three primer combinations of amplified fragment length polymorphism (AFLP) markers. Out of 750 fragments generated, 636 were polymorphic and 407 of them were restricted to a single species. STRUCTURE and PCoA analyses clearly separated morphologically different populations into six distinct genetic ones. The UPGMA analysis grouped the species into three main clusters: G1 grouped C. spinosa subsp. spinosa var. spinosa and C. sicula subsp. sicula; G2 grouped C. ovata subsp. ovata and C. orientalis and G3 clustered C. zoharyi and C. aegyptia. Populations from G1, G2 and G3 were mainly distributed in arid, subhumid, and semi-arid bioclimates, respectively. Additional genetic studies on Capparis could help to identify genes underlying speciation events and local adaptation to geographic areas leading to the development of breeding programs. PMID- 27697368 TI - HIV Stigma and Social Capital in Women Living With HIV. AB - Women living with HIV (WLWH) continue to experience HIV-related stigma. Social capital is one resource that could mitigate HIV stigma. Our cross-sectional study examined associations between social capital and HIV-related stigma in 135 WLWH in the San Francisco Bay Area. The mean age of study participants was 48 years; 60% were African American; 29% had less than a high school education; and 19% were employed. Age was significantly associated with perceived HIV stigma (p = .001), but total social capital was not. Women with lower Value of Life social capital scores had significantly higher total stigma scores (p = .010) and higher Negative Self-image stigma scores (p = .001). Women who felt less valued in their social worlds may have been more likely to perceive HIV stigma, which could have negative health consequences. This work begins to elucidate the possible relationships between social capital and perceived HIV stigma. PMID- 27697369 TI - Heart rate variability in patients with essential tremor: A cross sectional study. AB - OBJECTIVE: To investigate heart rate variability (HRV) in patients with Essential Tremor (ET) in comparison with patients with Parkinson's Disease (PD). METHODS: This is a cross sectional control study including 10 patients with ET, 10 patients with PD and 10 age-sex-matched controls. In patients and controls, we measured the components of HRV analysis in the frequency domain during a daytime period of 12-h. Selected HRV variables were low-frequency (LF) and high-frequency (HF), conventionally considered to be influenced by the sympathetic system and the parasympathetic system respectively. RESULTS: HRV variables, in patients with ET, were significantly different from those detected in PD patients and similar to those of controls while in PD patients, they were significantly different from those of controls. At cut off level of 654 ms2, LF component correctly distinguished ET patients versus PD with sensitivity, specificity, PPV and accuracy of 100%. By contrast, at cut off level of 737 ms2, HF component showed sensitivity, specificity, PPV and accuracy of 80%, 100%, 100%, and 86.67% respectively. DAT-SPECT and cardiac MIBG uptake were both normal in ET patients whereas they were markedly decreased in those with PD. CONCLUSIONS: In our study, the LF component of HRV analysis distinguishes ET patients from those with PD on an individual basis, thus representing a valid help in everyday clinical practice for differentiation between these patients in absence of scintigraphic investigations. PMID- 27697371 TI - Evaluation of model-based methods in estimating respiratory mechanics in the presence of variable patient effort. AB - Monitoring of respiratory mechanics is required for guiding patient-specific mechanical ventilation settings in critical care. Many models of respiratory mechanics perform poorly in the presence of variable patient effort. Typical modelling approaches either attempt to mitigate the effect of the patient effort on the airway pressure waveforms, or attempt to capture the size and shape of the patient effort. This work analyses a range of methods to identify respiratory mechanics in volume controlled ventilation modes when there is patient effort. The models are compared using 4 Datasets, each with a sample of 30 breaths before, and 2-3 minutes after sedation has been administered. The sedation will reduce patient efforts, but the underlying pulmonary mechanical properties are unlikely to change during this short time. Model identified parameters from breathing cycles with patient effort are compared to breathing cycles that do not have patient effort. All models have advantages and disadvantages, so model selection may be specific to the respiratory mechanics application. However, in general, the combined method of iterative interpolative pressure reconstruction, and stacking multiple consecutive breaths together has the best performance over the Dataset. The variability of identified elastance when there is patient effort is the lowest with this method, and there is little systematic offset in identified mechanics when sedation is administered. PMID- 27697370 TI - Differential associations between Social Anxiety Disorder, family cohesion, and suicidality across racial/ethnic groups: Findings from the National Comorbidity Survey-Adolescent (NCS-A). AB - The proposed research seeks to introduce a novel model relating Social Anxiety Disorder (SAD) and suicide outcomes (i.e., passive suicidal ideation, active suicidal ideation, and suicide attempts) in diverse adolescents. This model posits that family cohesion is one pathway by which suicide risk is increased for socially anxious youth, and predicts that the relationships between these variables may be of different strength in Latino and White subgroups and across gender. Data from a sample of Latino (n=1922) and non-Hispanic White (hereafter referred to as White throughout) (n=5648) male and female adolescents who participated in the National Comorbidity Survey-Adolescent were used for this study. Analyses were conducted using generalized structural equation modeling. Results showed that the mediation model held for White females. Further examination of direct pathways highlighted SAD as a risk factor unique to Latinos for active suicidal ideation and suicide attempt, over and above comorbid depression and other relevant contextual factors. Additionally, family cohesion showed a strong association with suicide outcomes across groups, with some inconsistent findings for White males. Overall, it appears that the mechanism by which SAD increases risk for suicidality is different across groups, indicating further need to identify relevant mediators, especially for racial/ethnic minority youth. PMID- 27697372 TI - Assessing Methanobrevibacter smithii and Clostridium difficile as not conventional faecal indicators in effluents of a wastewater treatment plant integrated with sludge anaerobic digestion. AB - Wastewater treatment plants (WWTP) are an important source of surface water contamination by enteric pathogens, affecting the role of environmental water as a microbial reservoir. We describe the release to the environment of certain anaerobes of human and environmental concern. The work was focused on emerging microbial targets. They are tracing, by RT-qPCR, on WWTP effluents, both liquid and solid, when an anaerobic digestion step is included. The focus is placed on Clostridium spp. with the specific quantification of Clostridium perfringens, as typical bioindicator, and Clostridium difficile, as emerging pathogen not only confined into nosocomial infection. Moreover methanogens were quantified for their involvement in the anaerobic digestion, and in particular on Methanobrevibacter smithii as major methanogenic component of the human gut microbiome and as not conventional faecal indicator. In the water samples, a reduction, statistically significant, in all microbial targets was observed (p < 0.01), 2 log for the total bacteria, 1.4 log for the Clostridium spp. and M. smithii, 1 log for total methanogens, C. perfringens and C. difficile. The AD process contribute to a significant change in microbial levels into the sludge for total bacteria and total methanogens (p < 0.01), both when the input sludge are primary and secondary, while for the presence of Clostridium spp. and C. difficile there was not a significant change. The produced data are innovative showing which is the diffusion of such anaerobic microorganisms throughout the WWTP and opening a discussion on the implementation of possible techniques for a more efficient microbial removal from effluents, particularly bio-solids, to reduce the potential release of pathogens into the environment.

This CS water represents a potential agricultural resource if the water is able to be chemically amended to comply with management guidelines. Stoichiometric quantities of sulphur and gypsum amendments can be used to neutralise the alkalinity and reduce the sodicity of CS water respectively. These amendments can either be mixed in-line at a water treatment plant or applied directly to land prior to the application of CS water (a practice termed land amendment irrigation - LAI). This study compared the efficacy of LAI with in-line chemical amendment of CS water and irrigation with non-saline, non-sodic and non-alkaline (good quality) water under field conditions in southern Queensland. Soil chemical properties, soluble Ca, Mg, K, Na, electrical conductivity (EC), pH, chloride and alkalinity, as well as saturated hydraulic conductivity were measured to determine the impact of the irrigation treatments on soil chemical and physical conditions. Irrigation of lucerne pasture using solid-set sprinklers applied a total of 6.7 ML/ha of each treatment irrigation water to the experimental plots over a 10-month period. Alkalinity was neutralised using LAI, with no increase in soil alkalinity observed. Soil sodicity did not exceed threshold electrolyte concentration values under either CS water irrigation treatment. Soil chemical and physical properties were comparable for both LAI and in-line chemical amendment of CS water. Soil saturated hydraulic conductivity was maintained under all irrigation treatments. Results showed that the constrained capacity of the irrigation system was unable to meet crop evapotranspiration demand. This resulted in accumulation of salt within the root-zone under the CS water treatments compared to the good quality water treatment. LAI successfully chemically amended Bowen Basin CS water facilitating its beneficial use for agricultural irrigation.

AB - One of the most vital supports to sustain human life on the planet earth is the agriculture system that has been constantly challenged in terms of yield. Crop losses due to insect pest attack even after excessive use of chemical pesticides, are major concerns for humanity and environment protection. By the virtue of unique properties possessed by micro and nano-structures, their implementation in Agri-biotechnology is largely anticipated. Hence, traditional pest management strategies are now forestalling the potential of micro and nanotechnology as an effective and viable approach to alleviate problems pertaining to pest control. These technological innovations hold promise to contribute enhanced productivity by providing novel agrochemical agents and delivery systems. Application of these systems engages to achieve: i) control release of agrochemicals, ii) site targeted delivery of active ingredients to manage specific pests, iii) reduced pesticide use, iv) detection of chemical residues, v) pesticide degradation, vi) nucleic acid delivery and vii) to mitigate post-harvest damage. Applications of micro and nano-technology are still marginal owing to the perception of low economic returns, stringent regulatory issues involving safety assessment and public awareness over their uses. In this review, we highlight the potential application of micro and nano-materials with a major focus on effective pest management strategies including safe handling of pesticides. PMID- 27697375 TI - Fate of sulfur mustard on soil: Evaporation, degradation, and vapor emission. AB - After application of sulfur mustard to the soil surface, its possible fate via evaporation, degradation following absorption, and vapor emission after decontamination was studied. We used a laboratory-sized wind tunnel, thermal desorber, gas chromatograph-mass spectrometry (GC-MS), and 13C nuclear magnetic resonance (13C NMR) for systematic analysis. When a drop of neat HD was deposited on the soil surface, it evaporated slowly while being absorbed immediately into the matrix. The initial evaporation or drying rates of the HD drop were found to be power-dependent on temperature and initial drop volume. Moreover, drops of neat HD, ranging in size from 1 to 6 MUL, applied to soil, evaporated at different rates, with the smaller drops evaporating relatively quicker. HD absorbed into soil remained for a month, degrading eventually to nontoxic thiodiglycol via hydrolysis through the formation of sulfonium ions. Finally, a vapor emission test was performed for HD contaminant after a decontamination process, the results of which suggest potential risk from the release of trace chemical quantities of HD into the environment. PMID- 27697376 TI - Complex mixtures of Pesticides in Midwest U.S. streams indicated by POCIS time integrating samplers. AB - The Midwest United States is an intensely agricultural region where pesticides in streams pose risks to aquatic biota, but temporal variability in pesticide concentrations makes characterization of their exposure to organisms challenging. To compensate for the effects of temporal variability, we deployed polar organic chemical integrative samplers (POCIS) in 100 small streams across the Midwest for about 5 weeks during summer 2013 and analyzed the extracts for 227 pesticide compounds. Analysis of water samples collected weekly for pesticides during POCIS deployment allowed for comparison of POCIS results with periodic water-sampling results. The median number of pesticides detected in POCIS extracts was 62, and 141 compounds were detected at least once, indicating a high level of pesticide contamination of streams in the region. Sixty-five of the 141 compounds detected were pesticide degradates. Mean water concentrations estimated using published POCIS sampling rates strongly correlated with means of weekly water samples collected concurrently, however, the POCIS-estimated concentrations generally were lower than the measured water concentrations. Summed herbicide concentrations (units of ng/POCIS) were greater at agricultural sites than at urban sites but summed concentrations of insecticides and fungicides were greater at urban sites. Consistent with these differences, summed concentrations of herbicides correlate to percent cultivated crops in the watersheds and summed concentrations of insecticides and fungicides correlate to percent urban land use. With the exception of malathion concentrations at nine sites, POCIS estimated water concentrations of pesticides were lower than aquatic-life benchmarks. The POCIS provide an alternative approach to traditional water sampling for characterizing chronic exposure to pesticides in streams across the Midwest region.

AB - Polycyclic aromatic hydrocarbons (PAH) have been listed by the United States Environmental Protection Agency (US EPA) and by the European Community as priority environmental pollutants. The removal of PAHs from soils, sediments and waste water has attracted attention of scientists and engineers for several decades. Electrochemical oxidation of PAH compounds in water, is receiving increasing attention, due to its convenience and simplicity. In this study we performed electrochemical oxidation of 16 EPA PAHs mixture in 10% NaCl aqueous solution in potentiostatic conditions, at voltage 1 V. Decrease of concentration of some individual PAHs, up to 70% referred to their starting concentration, after 60 min of electrolysis, was confirmed by UPLC/PDA analysis. In further work investigation was extrapolated to in situ removal of PAHs from concrete, as the medium where, to our knowledge, such way of PAH removal has not been investigated before. High concentrations of PAH contamination occurred in the concrete structure of the residential buildings in Belgrade in 2014. Application of DC voltage of 50 V between nickel and stainless steel electrodes packed in the concrete wall, moisturized with the 10% NaCl solution, led to considerable removal of the pollutants by oxidation process throughout the concrete.

AB - Uptake and accumulation by plants is a significant pathway in the migration and transformation of phthalate esters (PAEs) in the environment. However, limited information is available on the mechanisms of PAE metabolism in plants. Here, we investigated the metabolism of di-n-butyl phthalate (DnBP), one of the most frequently detected PAEs, in pumpkin (Cucurbita moschata) seedlings via a series of hydroponic experiments with an initial concentration of 10 mg L-1. DnBP hydrolysis occurred primarily in the root, and two of its metabolites, mono-n butyl phthalate (MnBP) and phthalic acid (PA), were detected in all plant tissues. The MnBP concentration was an order of magnitude higher than that of PA in shoots, which indicated MnBP was more readily transported to the shoot than was PA because of the former's dual hydrophilic and lipophilic characteristics. More than 80% of MnBP and PA were located in the cell water-soluble component except that 96% of MnBP was distributed into the two solid cellular fractions (i.e., cell wall and organelles) at 96 h. A 13-20% and 29-54% increase of carboxylesterase (CXE) activity shown in time-dependent and concentration dependent experiments, respectively, indicated the involvement of CXEs in plant metabolism of DnBP. The level of CXE activity in root subcellular fractions was in the order: the cell water-soluble component (88-94%) >> cell wall (3-7%) > cell organelles (3-4%), suggesting that the cell water-soluble component is the dominant locus of CXE activity and also the domain of CXE-catalyzed hydrolysis of DnBP. The addition of triphenyl phosphate, a CXE inhibitor, led to 43-56% inhibition of CXE activity and 16-25% increase of DnBP content, which demonstrated the involvement of CXEs in plant metabolism of DnBP. This study contributes to our understanding of enzymitic mechanisms of PAE transformation in plants. PMID- 27697380 TI - Developmental and neurotoxicity of the mosquito control larvicide. PMID- 27697381 TI - Presence of microplastic in the digestive tracts of European flounder, Platichthys flesus, and European smelt, Osmerus eperlanus, from the River Thames. AB - Like many urban catchments, the River Thames in London is contaminated with plastics. This pollutant is recorded on the river banks, in the benthic environment and in the water column. The present study was conducted to assess the extent of microplastic ingestion in two River Thames fish species, the European flounder (Platichthys flesus) and European smelt (Osmerus eperlanus). Samples were collected from two sites in Kent, England; Erith and Isle of Grain/Sheppey, near Sheerness, with the latter being more estuarine. The results revealed that up to 75% of sampled European flounder had plastic fibres in the gut compared with only 20% of smelt. This difference may be related to their diverse feeding behaviours: European flounder are benthic feeders whilst European smelt are pelagic predators. The fibres were predominantly red or black polyamides and other fibres included acrylic, nylon, polyethylene and polyethylene terephthalate and there was no difference in occurrence between the sites sampled. PMID- 27697382 TI - Effects of simulated acid rain on soil fauna community composition and their ecological niches. AB - Acid rain is one of the severest environmental issues globally. Relative to other global changes (e.g., warming, elevated atmospheric [CO2], and nitrogen deposition), however, acid rain has received less attention than its due. Soil fauna play important roles in multiple ecological processes, but how soil fauna community responds to acid rain remains less studied. This microcosm experiment was conducted using latosol with simulated acid rain (SAR) manipulations to observe potential changes in soil fauna community under acid rain stress. Four pH levels, i.e., pH 2.5, 3.5, 4.5, and 5.5, and a neutral control of pH 7.0 were set according to the current pH condition and acidification trend of precipitation in southern China. As expected, we observed that the SAR treatments induced changes in soil fauna community composition and their ecological niches in the tested soil; the treatment effects tended to increase as acidity increased. This could be attributable to the environmental stresses (such as acidity, porosity and oxygen supply) induced by the SAR treatments. In addition to direct acidity effect, we propose that potential changes in permeability and movability of water and oxygen in soils induced by acid rain could also give rise to the observed shifts in soil fauna community composition. These are most likely indirect pathways of acid rain to affect belowground community. Moreover, we found that nematodes, the dominating soil fauna group in this study, moved downwards to mitigate the stress of acid rain. This is probably detrimental to soil fauna in the long term, due to the relatively severer soil conditions in the deep than surface soil layer. Our results suggest that acid rain could change soil fauna community and the vertical distribution of soil fauna groups, consequently changing the underground ecosystem functions such as organic matter decomposition and greenhouse gas emissions.

PMID- 27697383 TI - Acute exposure to fine particulate matter and cardiovascular hospital emergency room visits in Beijing, China. AB - Fine particulate matter (PM2.5) air pollution outbreaks have recently occurred frequently in China. However, evidence of the associations between short-term exposure to PM2.5 and cardiovascular morbidity is still limited in China. This study aimed to evaluate the associations between PM2.5 and hospital emergency room visits (ERVs) for cardiovascular diseases in urban areas in Beijing. Daily counts of cardiovascular ERVs were collected from ten large general hospitals from Jan 1 to Dec 31, 2013. Air pollution data were obtained from the Beijing Environmental Protection Bureau including 17 monitoring stations. A generalized additive Poisson model was used to examine the associations between PM2.5 and cardiovascular ERVs after controlling for seasonality, day of the week, public holidays, influenza outbreaks, and weather conditions. In total, there were 56,221 cardiovascular ERVs during the study period. The daily mean PM2.5 concentration was 102.1 MUg/m3, ranging from 6.7 MUg/m3 to 508.5 MUg/m3. Per 10 MUg/m3 increase in PM2.5 was associated with a 0.14% (95% confidence interval [CI]: 0.01%-0.27%) increase in cardiovascular ERVs at lag3. Cumulative delayed estimates were greatest at lag0-5 (0.30%, 95% CI: 0.09%-0.52%). The estimates of percentage change in daily ERVs per 10 MUg/m3 increase in PM2.5 were 0.56% (95%CI: 0.16%-0.95%) for ischemic heart disease (IHD) at lag0-1, 0.81% (95%CI: 0.05%-1.57%) for heart rhythm disturbances (HRD) at lag0-1 and 1.21% (95%CI: 0.27%-2.15%) for heart failure (HF) at lag0, respectively. The effects of PM2.5 on IHD ERVs during high temperature days (>11.01 degrees C) were significantly higher than that on low temperature days (<=11.01 degrees C) at lag0, lag0-1, lag0-3 and lag0-5 (P < 0.05). The study suggests that PM2.5 has acute impacts on cardiovascular ERVs in Beijing, especially on IHD, HRD and HF. The effects of PM2.5 on IHD ERVs vary by temperature.

PMID- 27697386 TI - The forensic analysis of office paper using oxygen Isotope Ratio Mass Spectrometry, part 2: Characterising the source materials and the effect of production and usage on the delta18O values of cellulose and paper. AB - For casework applications, understanding the source processes used to create a material and the effects of those sources on the results obtained by Isotope Ratio Mass Spectrometry (IRMS) of a bulk material is important. Likewise, understanding the effect of environment, home/office printing processes and some forensic testing in at least a basic context, ensures that in casework, enough information on the effects of these variables is available during comparison and interpretation. In this study, which focuses on oxygen isotopic abundance measurements, both fractionation and mixing effects were observed within the pulping and production process. Also observed in the carbon isotopic experiments, sampling that included toner changed the measured isotopic abundance values of the paper and should be avoided in casework. Inkjet printing processes were not shown to have an effect on the paper oxygen abundance values. Samples that were treated for fingerprints using 1,2-Indandione-Zn prior to sampling showed the greatest risk for misinterpretation of whether two samples had originated from the same source. While this study provides a good basis and understanding of the effects of a range of factors on document paper oxygen isotope values, further testing for a range of specific casework scenarios is required and should be undertaken on a case by case basis as the need arises.

AB - OBJECTIVE: To investigate the effects of a prophylactic knee brace on knee joint kinetics and kinematics during netball specific movements. DESIGN: Repeated measures. SETTING: Laboratory. PARTICIPANTS: Twenty university first team level female netball players. OUTCOME MEASUREMENTS: Participants performed three movements, run, cut and vertical jump under two conditions (brace and no-brace). 3-D knee joint kinetics and kinematics were measured using an eight-camera motion analysis system. Knee joint kinetics and kinematics were examined using 2 * 3 repeated measures ANOVA whilst the subjective ratings of comfort and stability were investigated using chi-squared tests. RESULTS: The results showed no differences (p > 0.05) in knee joint kinetics. However the internal/external rotation range of motion was significantly (p < 0.05) reduced when wearing the brace in all movements. The subjective ratings of stability revealed that netballers felt that the knee brace improved knee stability in all movements. CONCLUSIONS: Further study is required to determine whether reductions in transverse plane knee range of motion serve to attenuate the risk from injury in netballers. PMID- 27697388 TI - A Comparison of Radial and Femoral Coronary Angiography in Patients From SNAPSHOT ACS, a Prospective Acute Coronary Syndrome Audit in Australia and New Zealand. AB - BACKGROUND: There is wide variation in the use of radial over femoral access for patients with ACS. This study evaluates the factors associated with the selection of radial versus femoral angiography in Australia and New Zealand and the effect of access site on clinical events in acute coronary syndrome (ACS) patients. METHODS: An analysis of the SNAPSHOT ACS audit was conducted during May 2012 across 286 hospitals in Australia and New Zealand. Data collected included baseline patient characteristics, hospital site details, treatment received, clinical events in-hospital and mortality at 18 months. Univariate and multivariable analyses were performed. RESULTS: Of the 1621 patients undergoing coronary angiography, access was through the femoral artery in 1043 (63%), and the radial in 578 (36%) patients. Radial access dominated in New Zealand (241 out of 327, 73.7%), compared to Australia (337 out of 1293, 26.1%, p=<0.001), with interstate variation (6% to 54%, p=<0.001). Independent predictors of access site included country of admission (Odds of radial, Aus v NZ OR 0.14, 95% CI 0.08 0.24, p=<0.0001), prior CABG surgery (OR 0.16, 95% CI 0.09-0.31, p=<0.0001), high GRACE score (90th decile) (OR 0.44, 95% CI 0.21-0.91, p=0.026) and admission to a centre with high annual PCI volume (>209 cases per year) (OR 1.86, 95% CI 1.06 3.26, p=0.03). After adjustment, there was no difference in clinical events in hospital or mortality at 18 months CONCLUSION: Coronary angiography in New Zealand rather than Australia is the strongest predictor of radial access in ACS patients. There was no difference in outcomes according to access site in this population based cohort study. PMID- 27697390 TI - Zoonotic tuberculosis in human beings caused by Mycobacterium bovis-a call for action. AB - Mycobacterium tuberculosis is recognised as the primary cause of human tuberculosis worldwide. However, substantial evidence suggests that the burden of Mycobacterium bovis, the cause of bovine tuberculosis, might be underestimated in human beings as the cause of zoonotic tuberculosis. In 2013, results from a systematic review and meta-analysis of global zoonotic tuberculosis showed that the same challenges and concerns expressed 15 years ago remain valid. These challenges faced by people with zoonotic tuberculosis might not be proportional to the scientific attention and resources allocated in recent years to other diseases. The burden of zoonotic tuberculosis in people needs important reassessment, especially in areas where bovine tuberculosis is endemic and where people live in conditions that favour direct contact with infected animals or animal products. As countries move towards detecting the 3 million tuberculosis cases estimated to be missed annually, and in view of WHO's end TB strategy endorsed by the health authorities of WHO Member States in 2014 to achieve a world free of tuberculosis by 2035, we call on all tuberculosis stakeholders to act to accurately diagnose and treat tuberculosis caused by M bovis in human beings.

AB - Palpation methods (PMs) have been proposed to guide clinicians in locating the thoracic transverse processes (TTPs). However, no studies have assessed the validity of TTPs palpation or the added value of musculoskeletal ultrasound (MSU). The objectives of the present study were (1) to explore the validity of TTPs location using palpation as commonly performed by clinicians, (2) to develop an accurate and valid PM, and (3) to assess the added value of MSU. A standardized procedure was used on six cadavers. It consisted in the insertion of markers through the T3, T5, T6 and T8 TTPs and spinous processes, which were identified using palpation and MSU. First, a fresh cadaver was used to explore the validity of the common palpation method. Since poor validity was observed, one intermediate and a final PMs were tested on a total of five Thiel-embalmed specimens. A descriptive analysis was performed and agreement between MSU and the final PM was determined. The final PM led to the proper determination of all TTPs on three specimens with a mean error of 4 +/- 1.8 mm in relation to the TTPs center. The coefficient of variations and root mean square errors were <=0.15 and 0.21 mm, respectively. Bland-Altman plot showed no differences between palpation and MSU. In conclusion, this study reports the validity of a new PM using multiple landmarks to guide TTPs determination and for which MSU does not seem to add value in accuracy. These results may have important clinical implications for clinicians using palpation. PMID- 27697393 TI - [The Paris Manifesto: It's time for new male contraceptives]. PMID- 27697394 TI - Review on crosstalk and common mechanisms of endocrine disruptors: Scaffolding to improve PBPK/PD model of EDC mixture. AB - Endocrine disruptor compounds (EDCs) are environment chemicals that cause harmful effects through multiple mechanisms, interfering with hormone system resulting in alteration of homeostasis, reproduction and developmental effect. Many of these EDCs have concurrent exposure with crosstalk and common mechanisms which may lead to dynamic interactions. To carry out risk assessment of EDCs' mixture, it is important to know the detailed toxic pathway, crosstalk of receptor and other factors like critical window of exposure. In this review, we summarize the major mechanism of actions of EDCs with the different/same target organs interfering with the same/different class of hormone by altering their synthesis, metabolism, binding and cellular action. To show the impact of EDCs on life stage development, a case study on female fertility affecting germ cell is illustrated. Based on this summarized discussion, major groups of EDCs are classified based on their target organ, mode of action and potential risk. Finally, a conceptual model of pharmacodynamic interaction is proposed to integrate the crosstalk and common mechanisms that modulate estrogen into the predictive mixture dosimetry model with dynamic interaction of mixture. This review will provide new insight for EDCs' risk assessment and can be used to develop next generation PBPK/PD models for EDCs' mixture analysis. PMID- 27697395 TI - Correlation of the predictive ability of early warning metrics and mortality for cardiac arrest patients receiving in-hospital Advanced Cardiovascular Life Support. AB - BACKGROUND: The Modified Early Warning Score (MEWS) helps identify patients experiencing a decline in physiological parameters that indicate risk for cardiac arrest (CA). OBJECTIVES: To assess the association between MEWS values and patient survival following in-hospital CA. METHODS: Retrospective cohort study of patients who experienced in-hospital CA. The relationship between CA survival and MEWS values as well as other risk factors such as age, gender and type of electrographic cardiac rhythms was analyzed using logistic regression. RESULTS: Survival rate to hospital discharge was 21%. Strong predictors for survival were MEWS values at hospital admission (p < .002), younger age (p < .005), ventricular fibrillation (p < .0001), and ventricular tachycardia (p < .0001). Gender and MEWS 4 hours prior to CA were not significantly associated with survival. CONCLUSIONS: Survival following CA was significantly associated with MEWS at hospital admission but not 4 hours prior to CA. The type of cardiac rhythm and age were also predictive of survival. PMID- 27697396 TI - Pediatric and neonatal transport in Spain, Portugal and Latin America. AB - OBJECTIVE: To study the organization of inter-hospital transport of pediatric and neonatal patients in Spain, Portugal and Latin America. DESIGN: An observational study was performed. An on-line survey was sent by email including questions about characteristics of national, regional and local health transport systems, vehicles, material, and composition of the transport team and their training. SETTING: Hospital pediatric healthcare professionals treating children in Spain, Portugal and Latin America RESULTS: A total of 117 surveys from 15 countries were analyzed. Of them, 55 (47%) come from 15 regions of Spain and the rest from Portugal and 13 Latin American countries. The inter-hospital transport of pediatric patients is unified only in the Spanish regions of Baleares and Cataluna and in Portugal. Chile has a mixed unified transport system for pediatric and adult patients. Only 51.4% of responders have an educational program for the transport personnel, and only in 36.4% of them the educational program is specific for pediatric patients. In Spain and Portugal the transport is executed mostly by public entities, while in Latin America public and private systems coexist. Specific pediatric equipment is more frequent in the transport teams in the Iberian Peninsula than in Latin American teams. The specific pediatric transport training is less frequent for teams in Latin America than on Spain and Portugal. CONCLUSIONS: There is a great variation in the organization of children transport in each country and region. Most of countries and cities do not have unified and specific teams of pediatric transport, with pediatric qualified personnel and specific material. PMID- 27697397 TI - Implants in free fibula flap supporting dental rehabilitation - Implant and peri implant related outcomes of a randomized clinical trial. AB - OBJECTIVES: The objective of this study was to assess the difference in success rates of implants when using two or four implant-supported-overdentures following segmental mandibular reconstruction with fibula free flap. METHODS AND DESIGNS: This prospective, parallel designed, randomized clinical study was conducted with 1:1 ratio. At baseline, all participants already had segmental reconstruction of mandible with free fibula flap. The participants were randomized into two groups: Group-I received implant-supported-overdentures on two tissue-level implants and Group-II received implant-supported-overdentures on four tissue-level implants. Success rates of the implants were evaluated at 3 months, 6 months and 12 months following implant loading using marginal bone level changes as well as peri implant indices (Buser et al., 1990). RESULTS: 52 patients were randomized into two treatment groups (26 each), out of which 18 patients (36 implants) of Group-I and 17 patients (68 implants) of Group-II were evaluated. One implant in Group-I was lost due to infective complications and one patient in the same group had superior barrel necrosis. There was a statistically significant increase at both time points (p = 0.03, p = 0.04 at 6 months, 12 months) in the amount of marginal bone loss in Group-I (0.4 mm, 0.5 mm at 6 months, 12 months) as compared to Group II (0.1 mm, 0.2 mm at 6 months, 12 months). There were no clinically significant changes peri-implant parameters between both groups. Peri-implant soft tissue hyperplasia was seen in both groups, 32% of implants at 3-months, 26% at 6-months and 3% at 12-months follow-up. CONCLUSION: The results of this study show that patients with 2-implant-supported-overdentures had higher marginal bone loss as compared to patients with 4-implant-supported-overdentures. There were no clinically significant differences in peri-implant soft tissue factors in patients with 2- or 4-implant-supported-overdentures. Hyperplastic peri-implant tissues are common in the early implant-loading phase and tend to decrease over time under appropriate management. PMID- 27697398 TI - Reconstruction of the maxilla following hemimaxillectomy defects with scapular tip grafts and dental implants. AB - BACKGROUND: Treatment of post-resective defects of the maxilla can be challenging and usually requires dental obturation or microvascular reconstruction. As compared to soft-tissue microvascular grafts, bone reconstruction can additionally allow for facial support and retention of dental implants. The aim of this study was to evaluate scapular tip grafts with respect to their applicability for maxillary reconstruction and their potential to retain dental implants for later dental rehabilitation. MATERIALS AND METHODS: In this retrospective study, 14 patients with hemimaxillectomy defects were reconstructed with free scapular tip grafts, oriented horizontally, to rebuild the palate and alveolar ridge. After bone healing, three-dimensional virtual implant planning was performed, and a radiographic guide was fabricated to enable implant placement in the optimal anatomic and prosthetic position. All patients' mastication and speech were evaluated, along with the extent of defect closure, suitability of the graft sites for implant placement, and soft-tissue stability. Pre- and postsurgical radiographs were also evaluated. RESULTS: A good postoperative outcome was achieved in all patients, with complete closure of maxillary defects that were class II, according to the system of Brown and Shaw. Additional bone augmentation was necessary in two patients in order to increase vertical bone height. Patients were subsequently treated with 50 dental implants to retain dental prostheses. In all cases, additional soft-tissue surgery was necessary to achieve a long-term stable periimplant situation. No implants were lost during the mean observation period of 34 months. CONCLUSIONS: Due to its specific form, the scapular tip graft is well suited to reconstruct the palate and maxillary alveolar ridge and to enable subsequent implant-retained rehabilitation. Due to the limited bone volume, an accurate three-dimensional graft orientation is essential. Furthermore, most cases require additional soft tissue surgery to achieve a long-term stable periimplant situation. PMID- 27697399 TI - Osseointegration and implant stability of extraoral implants in Gottingen minipigs after irradiation. AB - OBJECTIVES: The aim of this study was to compare the influence of implant surface treatment and irradiation dose on implant stability and osseointegration of 144 extraoral implants in irradiated frontal bone of minipigs. MATERIAL AND METHODS: 144 implants with 3 different surface treatments (machined, etched and HAVD coated) were implanted in the frontal bone of 16 Gottingen minipigs. Three groups of four pigs received radiation with equivalent doses of 25, 50 and 70 Gy, and one group served as control. Resonance frequency analysis (RFA) was performed recording Implant Stability Quotients (ISQ) at implant placement and 3 months thereafter. Removal torque was measured whilst removing specific implants after 3 months. In addition, the bone-to-implant contact (BIC) was analyzed. RESULTS: Evaluation of ISQ, BIC-values showed no significant difference between the different surface treatments in irradiated and non-irradiated bone. Removal torque revealed statistically significant differences between machined and HAVD coated implants in the irradiated bone. CONCLUSIONS: Implant stability and osseointegration, based on Removal Torque showed significant higher results for the HAVD-coated implants. No significant difference was observed between the irradiated and non-irradiated animals. This study shows that HAVD-coated extraoral implants can potentially be used for craniofacial rehabilitation in non irradiated and irradiated bone. PMID- 27697400 TI - Lack of effectiveness of antibiotics in chronic low back pain with Modic 1 changes. PMID- 27697401 TI - High prevalence of dementia in women with osteoporosis. AB - INTRODUCTION: Alzheimer's disease or other Dementias (ADD) and postmenopausal osteoporosis are two major public health problems with a huge impact on mortality. Here, we examined the prevalence of ADD in postmenopausal women with osteoporosis, monitored within a dedicated fracture liaison service. METHODS: We conducted a cross-sectional observational study in a population of 2041 women, visiting the university hospital of Saint-Etienne for a peripheral fragility fracture. We assessed the prevalence of ADD among these patients and compared to French population. We also compared the characteristics of women with ADD and without ADD. RESULTS: ADD prevalence was on average 13.5% in the population of interest with a mean age of 85years. As women with ADD were older than women without ADD, the prevalence of the disease significantly increased with age as 0%, 1.8%, 13% and 29.7% in<55, 55-74, 75-79 and 85-89years old groups, respectively. Proximal femoral fracture was the most frequent fracture (77%) followed by wrist fracture (13%), and then proximal humerus fracture (10%). ADD prevalence observed in our study was 3 to 4 times the ADD prevalence in France. Despite the overall increase of the ADD prevalence with age, it was still 2.2 and 1.9 times that of the French female population in the 80-84 and 85-89 age groups respectively. CONCLUSION: ADD prevalence was higher in postmenopausal women with severe osteoporosis, especially those with femoral fractures. Thus, our results incite to a more efficient care of this population with a high risk of fracture and mortality. PMID- 27697402 TI - The posterior-based buccinator myomucosal flap (Bozola's flap). AB - Based on a case of reconstruction after oncologic resection of the hard palate, the authors document the key technical points for harvesting a posterior-based buccinator myomucosal flap (Bozola's flap), and its limitations and indications after oncologic resection of tumors originating from the oral cavity and/oropharynx. PMID- 27697403 TI - The helicopter as a caring context: Experiences of people suffering trauma. AB - INTRODUCTION: When emergency medical services (EMS) are needed, the choice of transport depends on several factors. These may include the patient's medical condition, transport accessibility to the accident site and the receiving hospital's resources. Emergency care research is advancing, but little is known about the patient's perspective of helicopter emergency medical services (HEMS). AIM: The aim of this study was to describe trauma patients' experiences of HEMS. METHOD: Thirteen persons (ages 21-76) were interviewed using an interview guide. Data were analyzed using qualitative content analysis. FINDINGS: The analysis resulted in three themes: Being distraught and dazed by the event - patients experienced shock and tension, as well as feelings of curiosity and excitement. Being comforted by the caregivers - as the caregivers were present and attentive, they had no need for relatives in the helicopter. Being safe in a restricted environment - the participants' injuries were taken seriously and the caregivers displayed effective teamwork. CONCLUSION: For trauma patients to be taken seriously and treated as 'worst cases' enables them to trust their caregivers and 'hand themselves over' to their care. HEMS provide additional advantageous circumstances, such as being the sole patient and having proximity to a small, professional team. PMID- 27697404 TI - Comparison of Canadian and Swiss Surgical Training Curricula: Moving on Toward Competency-Based Surgical Education. AB - OBJECTIVE: Quality of surgical training in the era of resident duty-hour restrictions (RDHR) is part of an ongoing debate. Most training elements are provided during surgical service. As exposure to surgical procedures is important but time-consuming, RDHR may affect quality of surgical training. Providing structured training elements may help to compensate for this shortcoming. DESIGN: This binational anonymous questionnaire-based study evaluates frequency, time, and structure of surgical training programs at 2 typical academic teaching hospitals with different RDHR. SETTING: Departments of Surgery of University of Basel (Basel, Switzerland) and the Queen's University (Kingston, Ontario, Canada). PARTICIPANTS: Surgical consultants and residents of the Queen's University Hospital (Kingston, Ontario, Canada) and the University Hospital Basel (Basel, Switzerland) were eligible for this study. RESULTS: Questionnaire response rate was 37% (105/284). Queen's residents work 80 hours per week, receiving 7 hours of formal training (8.8% of workweek). Basel residents work 60 hours per week, including 1 hour of formal training (1.7% of working time). Queen's faculty and residents rated their program as "structured" or "rather structured" in contrast to Basel faculty and residents who rated their programs as "neutral" in structure or "unstructured." Respondents identified specific structured training elements more frequently at Queen's than in Basel. Two-thirds of residents responded that they seek out additional surgical experiences through voluntary extra work. Basel participants articulated a stronger need for improvement of current surgical training. Although Basel residents and consultants in both institutions fear negative influence of RDHR on the training program, this was not the case in Queen's residents. CONCLUSIONS: Providing more structured surgical training elements may be advantageous in providing optimal quality surgical education in an era of work-hour restrictions. PMID- 27697405 TI - Total hip replacement in young non-ambulatory cerebral palsy patients. AB - INTRODUCTION: The everyday life of a non-ambulatory adolescent or young adult with cerebral palsy can be severely impaired by a painful or stiff hip. The usual surgical solutions such as proximal femoral resection (PFR) are not entirely satisfactory for pain relief, and are mutilating. HYPOTHESIS: A retrospective study assessed the impact of total hip replacement (THR) on such impairment, on the hypothesis that it is more effective than PFR in relieving pain, without aggravating disability. PATIENTS AND METHODS: The surgical technique consisted in implanting a dual-mobility prosthesis with uncemented acetabular component and cemented femur, after upper femoral shaft shortening and short hip-spica cast immobilization. Forty THRs were performed in 33 patients, including 31 with multiple disability. Follow-up assessment focused on change in functional status, pain, and range of motion. RESULTS: Mean follow-up was 5 years. Pain was more or less entirely resolved. Improvement in range of motion was less striking, and there was no significant change in functional status. There were 2 general, 2 septic and 10 mechanical complications, 6 of which required surgical revision. DISCUSSION: In non-ambulatory cerebral palsy, THR provided much better alleviation of pain than found with PFR treatment. It should be reserved for patients able to withstand fairly long surgery and with femur size compatible with implantation of a femoral component, however small. LEVEL OF EVIDENCE: IV, retrospective study. PMID- 27697406 TI - Diagnostic value of ultrasonography in elbow trauma in children: Prospective study of 34 cases. AB - INTRODUCTION: Among the various elbow injuries in children that initially have normal radiographs, a certain number of occult fractures are only diagnosed correctly after the fact, during a follow-up visit. PURPOSE: This study evaluated the diagnostic contribution of ultrasonography in the treatment of acute elbow injuries in children and the strategic and economic impact of using this tool alongside radiography. MATERIALS AND METHODS: During this prospective study performed between January 1 and April 1 2014, elbow ultrasonography was performed within 6 days in all children under 15 years of age with a suspected occult fracture. The ultrasonography exam looked for lipohemarthrosis, the posterior fat pad sign and cortical disruption. If no fracture was visible on ultrasonography, a removable splint was given to the patient to relieve pain, and no radiological or clinical follow-up was scheduled. The patients were contacted again at least 15 days later to determine whether an undetected fracture was present. Lastly, we evaluated the cost of treatment with and without ultrasonography in the cases where no fracture was diagnosed. RESULTS: In 13 cases, ultrasonography revealed lipohemarthrosis and a fat pat sign, with cortical disruption also present in 11 of these cases. In two cases, the diagnosis was made based solely on the presence of lipohemarthrosis and a fat pat sign. There were seven lateral condyle fractures, two medial epicondyle fractures and two supracondylar fractures. Among the 21 patients with normal ultrasonography, no fracture was diagnosed later on. In patients without a fracture, using ultrasonography resulted in a cost savings of ?29.10 per patient versus not using it. CONCLUSION: In our study, ultrasonography is a sensitive examination for the diagnosis of occult elbow fractures in children. When the radiography and ultrasonography are both normal, the possibility of fracture can be rule out definitively, which reduces the need for immobilization, follow-up and treatment costs. The findings of this preliminary study should be validated with a larger prospective study. PMID- 27697407 TI - Utility of prognostic scoring systems in management of hepatocellular carcinoma.

PMID- 27697410 TI - Time Dependence of Radiation-induced Hypothalamic-Pituitary Axis Dysfunction in Adults Treated for Non-pituitary, Intracranial Neoplasms. AB - AIMS: Hypothalamic-pituitary axis (HPA) dysfunction is a sequela of cranial radiotherapy. The purpose of this study was to use endocrine data from existing publications to characterise the baseline endocrine status, the effects of radiotherapy on the HPA during the first follow-up year and the time dependence of radiation-induced HPA dysfunction in patients treated with radiotherapy for non-pituitary intracranial neoplasms. MATERIALS AND METHODS: A systematic search of databases was carried out for articles that reported the results of endocrine testing for patients aged 16 years and older who were treated with neurosurgery for non-pituitary intracranial neoplasms or radiotherapy for nasopharyngeal neoplasms. To analyse the radiotherapy-related changes in hormone levels over time, long-term prospective endocrine data from nasopharyngeal studies were normalised to baseline hormone data and fitted to an exponential decay model. This process was repeated with normalisation to year 1 hormone data. RESULTS: Eight unique articles met eligibility criteria. HPA dysfunction occurred in 21.6 64.7% of patients who were assessed for endocrinopathies following neurosurgery. Studies on the early effects of radiotherapy on nasopharyngeal patients showed statistically significant changes in growth hormone, luteinizing hormone and follicle stimulating hormone levels during the first year of follow-up. Time dependence modelling showed that normalisation to year 1 hormone levels yield exponential equations with stronger measures of goodness of fit. CONCLUSION: HPA dysfunction in patients treated for non-pituitary intracranial neoplasms is probably a result of both neurosurgery and radiotherapy treatments. Although statistically significant endocrine changes can occur during this first year of follow-up, those documented at year 1 may be more predictive of subsequent HPA dysfunction. PMID- 27697409 TI - The Ability of Patient-Symptom Questionnaires to Differentiate PVFMD From Asthma. AB - OBJECTIVES: Goals of the current study were to (1) conduct initial validation of a new Paradoxical Vocal Fold Movement Disorder Screening Questionnaire (PVFMD SQ); (2) determine if symptom-based questionnaires can discriminate between patients with confirmed PVFMD and those with diagnosed uncontrolled asthma without clinical suspicion for PVFMD; and (3) determine if a new questionnaire with diagnostic specificity could be created from a combination of significant items on previously validated questionnaires. METHODS: This is a prospective, case-controlled study of patients with PVFMD only and asthma only, who completed five questionnaires: Dyspnea Index, Reflux Symptom Index, Voice Handicap Index 10, Sino-Nasal Questionnaire, and PVFMD-SQ. Factor analysis was completed on the new PVFMD-SQ, and the discrimination ability of selected factors was assessed by receiver operating characteristics curve. The factor with the greatest discriminatory ability was selected to create one diagnostic questionnaire, and scores for each participant were calculated to estimate how well the factor correlated with a PVFMD or asthma diagnosis. Mean scores on all questionnaires were compared to test their discriminatory ability. RESULTS: Patients with PVFMD showed greater voice handicap and reflux symptoms than patients with asthma. A 15 item one-factor questionnaire was developed from the original PVFMD-SQ, with a sensitivity of 89% and specificity of 73% for diagnosing asthma versus PVFMD. The combined questionnaires resulted in four factors, none of which showed discriminatory ability between PVFMD and asthma. CONCLUSION: This study represents the first time that a patient symptom-based screening tool has shown diagnostic sensitivity to differentiate PVFMD from asthma in a cohort of symptomatic patients. PMID- 27697411 TI - Management of Early-stage Hodgkin Lymphoma: A Practice Guideline. AB - In the past, treatment for patients with early-stage Hodgkin lymphoma consisted mainly of radiotherapy. Now, chemotherapy alone and chemoradiotherapy are treatment options. These guidelines aim to provide recommendations on the optimal management of early-stage Hodgkin lymphoma. We conducted a systematic review searching MEDLINE, EMBASE, the Cochrane Library and other literature sources from 2003 to 2015, and applied the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Two authors independently reviewed and selected studies, and appraised the evidence quality. The document underwent internal and external review by content, methodology experts, a patient representative and clinicians in Ontario. We have issued recommendations for patients with classical Hodgkin lymphoma and with nodular lymphocyte predominant Hodgkin lymphoma; with favourable and unfavourable prognosis; and for the use of positron emission tomography to direct treatment. We have provided our interpretation of the evidence and considerations for implementation. Examples of recommendations are: 'Patients with early-stage classical Hodgkin lymphoma should not be treated with radiotherapy alone'; 'chemotherapy plus radiotherapy or chemotherapy alone are recommended treatment options for patients with early-stage non-bulky Hodgkin lymphoma'; 'The Working Group does not recommend the use of a negative interim positron emission tomography scan alone to identify patients with early-stage Hodgkin lymphoma for whom radiotherapy can be omitted without a reduction in progression-free survival'. Through the use of GRADE, recommendations were geared towards patient important outcomes and their strength reflected the available evidence and its interpretation from the patients' point of view.

PMID- 27697413 TI - Plant phosphates, phytate and pathological calcifications in chronic kidney disease. AB - Phytate, or myo-inositol 1,2,3,4,5,6-hexakis dihydrogen phosphate (InsP6), is a naturally occurring phosphorus compound that is present in many foods, mainly legumes, whole grains and nuts. Patients with chronic kidney disease (CKD) have cardiovascular disease mortality up to 30times higher than the general population. Vascular calcifications (VCs) directly contribute to overall morbidity and mortality, especially in CKD. In part, this high mortality is due to elevated levels of phosphorus in the blood. Therefore, control of dietary phosphorus is essential. Dietary phosphorus can be classified according to its structure in organic phosphorus (plant and animal) and inorganic (preservatives and additives). Plant-phosphorus (legumes and nuts), mainly associated with InsP6, is less absorbable by the human gastrointestinal tract as the bioavailability of phosphorous from plant-derived foods is very low. Recent data indicate that restriction of foods containing plant phosphates may compromise the adequate supply of nutrients that have a beneficial effect in preventing cardiovascular events, such as InsP6 or fibre found in legumes and nuts. Experimental studies in animals and observational studies in humans suggest that InsP6 can prevent lithiasis and VCs and protect from osteoporosis. In conclusion, we need prospective studies to elucidate the potential benefits and risks of phytate (InsP6) through the diet and as an intravenous drug in patients on haemodialysis. PMID- 27697414 TI - Delphi consensus on the diagnosis and management of dyslipidaemia in chronic kidney disease patients: A post hoc analysis of the DIANA study. AB - BACKGROUND AND OBJECTIVES: This post hoc study analysed the perception of the relevance of chronic kidney disease (CKD) in dyslipidaemia screening and the choice of statin among primary care physicians (PCPs) and other specialists through a Delphi questionnaire. METHODS: The questionnaire included 4blocks of questions concerning dyslipidaemic patients with impaired carbohydrate metabolism. This study presents the results of the impact of CKD on screening and the choice of statin. RESULTS: Of the 497 experts included, 58% were PCPs and 42% were specialists (35, 7% were nephrologists). There was consensus by both PCPs and specialists, with no difference between PCPs and specialists, that CKD patients should undergo a dyslipidaemia screening and that the screening should be part of routine clinical practice. However, there was no consensus in considering the estimated glomerular filtration rate (eGFR) (although there was consensus among PCPs and nephrologists), or considering albuminuria when selecting a statin, or in determining albuminuria during follow-up after having initiated treatment with statins (although there was consensus among the nephrologists). CONCLUSIONS: The consensus to analyse the lipid profile in CKD patients suggests acknowledgment of the high cardiovascular risk of this condition. However, the lack of consensus in considering renal function or albuminuria, both when selecting a statin and during follow-up, suggests a limited knowledge of the differences between statins in relation to CKD. Thus, it would be advisable to develop a guideline/consensus document on the use of statins in CKD. PMID- 27697415 TI - Use of suborbicularis oculi fat flap to cover peri-orbital bone exposure. AB - Wide resection of recurrent basal cell carcinoma (BCC) in the peri-orbital infraorbital-nasal area may include periosteum resection with maxillary or nasal bone exposure. The absence of vascularized periosteum makes the defect ungraftable and local flaps are often required. As an alternative to a large single flap or a combination of flaps, it is possible to turn the ungraftable portion of the defect into a graftable one. The suborbicularis oculi fat (SOOF) flap is an advancement flap that is used in aesthetic surgery for midface rejuvenation. The use of the SOOF flap along with a full-thickness skin graft, as an alternative to the use of other standardized flaps to cover defects in the peri-orbital-infraorbital-nasal area with avascularized tissue or noble structure exposure, is reported herein. As an immediate single-stage reconstruction, this procedure leaves other flap options intact in the event of re-operation for a recurrent tumour.

AB - Intracellular transport of organelles can be driven by multiple motor proteins that bind to the lipid membrane of the organelle and work as a team. We review present knowledge on how lipids orchestrate the recruitment of motors to a membrane. Looking beyond recruitment, we also discuss how heterogeneity and local mechanical properties of the membrane may influence function of motor-teams. These issues gain importance because phagocytosed pathogens use lipid-centric strategies to manipulate motors and survive in host cells. PMID- 27697417 TI - Implementation of the French national consensus for the management of ulcerative colitis into clinical practice. AB - BACKGROUND: Recently, treatment algorithms were developed in France additionally to ECCO recommendations that should be used as reference for ulcerative colitis (UC) management. Nevertheless, their implementation in clinical practice remains challenging. AIMS: To evaluate the prevalence of the use of these UC management algorithms in 127 patients followed by private gastroenterologists. METHODS: Charts of all UC patients seen during the year 2015 (n=127) by 10 gastroenterologists were reviewed. The gastroenterologist's management was then compared to the corresponding algorithm situation and, in case of disagreement, analysed by an expert committee. RESULTS: 94.5% of patients corresponded to a clinical situation described in algorithms. Gastroenterologist's management was adequate to the corresponding algorithm situation in 74.2% of cases. Among the 31 cases of disagreement, the gastroenterologist's decision differed from the algorithm position in 21 cases, and in 76.2% of cases the expert committee would have made the same decision. In the remaining 10 cases, the decision differed from the corresponding algorithm for reasons independent from the gastroenterologist (patient's choice etc.). CONCLUSIONS: French national algorithms for UC management allowed coverage of 95% of clinical cases in real world. In three quarters of cases, these algorithms were strictly followed by private gastroenterologists. Dissemination of these algorithms could optimize and strengthen the practitioner's choice.

PMID- 27697419 TI - Nonalcoholic fatty liver disease is associated with coronary artery calcification: A systematic review and meta-analysis. AB - BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is associated increased cardiovascular events and mortality. Coronary artery calcium scanning (CAC) is the robust predictor of coronary events in the asymptomatic individuals. Several recent studies have investigated the association between NAFLD and this surrogate marker. Thus, we conducted a systematic review and meta-analysis to better characterize the association between NAFLD and CAC. METHODS: MEDLINE and EMBASE were searched through May 2016. Primary outcome was the association between NAFLD and CAC. Pooled odds ratio (OR) and 95% confidence interval (CI) from multivariable-adjusted estimates were calculated using a random-effects model. The between-study heterogeneity of effect-size was quantified using the Q statistic and I2. RESULTS: Data were extracted from 16 studies (all cross sectional studies) involving 16,433 NAFLD patients and 41,717 controls. NAFLD is significantly associated with CAC score >0 and CAC score >100 with pooled OR of 1.41 (95%CI 1.26-1.57, Pheterogeneity=0.07, I2=66%) and 1.24 (95%CI 1.02-1.52, Pheterogeneity=0.10, I2=42%). CONCLUSIONS: NAFLD is associated with increased coronary artery calcification independent of traditional risk factors. The assessment of coronary artery calcium may be useful in identifying NAFLD patients at risk of future cardiovascular events.

Evaluating the effectiveness of sticker prompts for encouraging household food waste recycling behaviour. AB - This Randomised Control Trial (RCT) investigated the effectiveness of using stickers as a visual prompt to encourage the separate collection of household food waste for recycling in two local authorities in South East England. During a baseline period of up to 15weeks, separately collected food waste was weighed (in tonnes) and averaged across households in both treatment (N=33,716 households within 29 defined areas) and control groups (N=30,568 households within 26 areas). A sticker prompt was then affixed to the lids of refuse bins in the treatment group area only. Weights for both groups were subsequently measured across a 16-week experimental period. Results showed that, in the control group, there was no change in the average weight of food waste captured for recycling between the baseline and experimental period. However, there was a significant increase (20.74%) in the treatment group, and this change in behaviour persisted in the longer term. Sticker prompts therefore appear to have a significant and sustained impact on food waste recycling rates, while being simple, practically feasible and inexpensive (L0.35 per household) for local authorities to implement at scale.

PMID- 27697424 TI - Green and facile method for the recovery of spent Lithium Nickel Manganese Cobalt Oxide (NMC) based Lithium ion batteries. AB - The research reports a novel green method to use citrus fruits for the management of spent NMC based lithium ion batteries (LIBs). Citrus fruit juice (CJ) can provide an excellent chemical combination to remove the binder and support the leaching with efficiency in between 94% to 100%. CJ have many advantages in LIBs recycling as an economic and green method due to rich in many organic acids like citric and malic acid as complexing agents with ascorbic acid and citrus flavonoids, for the reduction of many heavy metals. Application of CJ can avoid the use of N-Methylpyrrolidine, gamma-Butyrolactone, dimethylformamide, and dimethyl sulfoxide like toxic solvents commonly used for peeling off Al/Cu. Furthermore, counterions (like Na+, Mg+, Ca2+) present in CJ was responsible for the improvement in the leaching efficiency of organic acids. A mechanistic pattern of the overall reaction was also proposed and duly supported by various spectroscopic techniques. Binder removal experiment was supported by analytical techniques like XRD, XRF, IR, and FE-SEM, while the metal concentration was monitored by using ICP-MS analysis.

AB - BACKGROUND: The epidemiology and etiology of diffuse idiopathic skeletal hyperostosis (DISH) remain obscure. To date, to the best of our knowledge, there is no study that precisely evaluated the prevalence of thoracic DISH based on computed tomography (CT) data in large number of non-operated cohort with wide age distribution. METHODS: The participants of this study were the consecutive patients who have undergone chest CT for the examination of pulmonary diseases in our institute. The patients with previous thoracic spine surgery and younger than 15 years old were excluded. Chest CT data were reconstructed in the condition suitable for bone evaluation by the software application. Definitive diagnosis of DISH was determined according to the criteria established by Resnick and Niwayama. Prevalence and distribution of thoracic DISH were reviewed and the data was statistically analyzed. RESULTS: Total 3013 patients (1261 females and 1752 males) with the mean age of 65 years were recruited. The CT-based evidence of thoracic DISH was noted in 261 individuals (31 females and 230 males) (8.7%), and their mean age was 73 years. Statistical analyses revealed that thoracic DISH had a significant male preponderance. The mean age of thoracic DISH positive individuals was significantly higher than that of thoracic DISH negative individuals. There was significant difference of bone mass index (BMI) between thoracic DISH positive and negative individuals. Thoracic DISH was noted after the age of 40s with the highest distribution found at the age of 70s. No thoracic DISH localizes only higher thoracic region was found. CONCLUSIONS: The CT-based prevalence of thoracic DISH in Japanese was 8.7%. Thoracic DISH has a significant predisposition to elderly male with high BMI. PMID- 27697427 TI - The yolky thecoma. PMID- 27697428 TI - Impact of scorpion venom as an acute stressor on the neuroendocrine-immunological network. AB - Although immunomodulatory property and many other pharmaceutical applications of scorpion venom have been addressed before, no studies were reported about its application as a neuroimmunomodulator at therapeutic dose. In this study, we conceptualized the property of scorpion venom, capable of inducing the acute pain and neurotoxicity can cause acute stress resulting in the modulation of immune cells through HPA axis. The whole venom from Hottentotta rugiscutis, a widely seen scorpion in the region of eastern Karnataka, was extracted and injected a single dose of 1 mg/kg b.w. to Swiss albino mice and then erythrocytes and leukogram were measured. Whole brain AChE activity, corticosterone, cytokines and NO levels in plasma were also evaluated at various time points. Hrv didn't show any histopathological changes in the lymphoid organs and at the site of injection. However, lymphocytes and neutrophils did get altered at 2 h post injection. Plasma corticosterone, cytokine levels such as IL-1beta, IL-6, TNF alpha and IL-10 and the AChE activity were significantly increased in a time dependent manner. Based on these results, it may be predicted, Hrv's ability to cause acute stress resulted in the activation of HPA axis, which stimulates the release of glucocorticoid hormones which in turn elicits the immunomodulation of leukocytes by altering the levels of pro and anti-inflammatory cytokines. Thus, we can conclude, the impact of acute stress induced by Hrv can intercommunicate the signals between neuroendocrine-immune systems. PMID- 27697429 TI - Longer Versus Shorter Duration of Supervised Rehabilitation After Lung Transplantation: A Randomized Trial. AB - OBJECTIVE: To investigate the effects of a supervised longer- (14wk) versus shorter-duration (7wk) rehabilitation program after lung transplantation (LTX). DESIGN: Randomized controlled trial. SETTING: Outpatient rehabilitation gym setting. PARTICIPANTS: Post-LTX patients aged >=18 years (N=66; 33 women; mean age, 51+/-13y) who had undergone either single LTX or bilateral LTX. INTERVENTION: Outpatient rehabilitation program consisting of thrice-weekly sessions with cardiovascular training on bike ergometer and treadmill plus upper and lower limb strength training. MAIN OUTCOME MEASURES: Measures were taken at baseline, 7 weeks, 14 weeks, and 6 months by assessors who were blinded to group allocation. Functional exercise capacity was measured by the 6-minute walk test (6MWT). Strength of quadriceps and hamstrings was measured on an isokinetic dynamometer and recorded as average peak torque of 6 repetitions for both muscles. Quality of life (QOL) was assessed with the Medical Outcomes Study 36 Item Short-Form Health Survey. RESULTS: Of the participants, 86% had bilateral LTX and 41% had primary diagnosis of chronic obstructive pulmonary disease. The 6MWT increased in both groups with no significant difference between groups at any time point (mean 6mo 6MWD: short, 590+/-85m vs long, 568+/-127m; P=0.5). Similarly, at 6 months, there was no difference between groups in quadriceps average peak torque (mean, 115+/-38Nm vs 114+/-40Nm, respectively; P=.59), hamstring average peak torque (57+/-18Nm vs 52+/-19Nm, respectively; P=.36), or mental or physical health domains of quality of life. CONCLUSIONS: Shorter duration (7wk) of rehabilitation achieves comparable outcomes with 14 weeks of supervised rehabilitation for functional exercise capacity, lower limb strength, and quality of life at 6 months after LTX. PMID- 27697431 TI - NF-Y and SP transcription factors - New insights in a long-standing liaison. AB - For long it has been recognized that CCAAT boxes and GC-rich elements co-occur in many human and murine promoters within 100bp upstream of the transcription start site. The trimeric transcription factor NF-Y is the major CCAAT box-binding factor, and members of the SP family of transcription factors are the major GC box-binding proteins. Recent chromatin immunoprecipitations coupled with high throughput sequencing (ChIP-seq) have examined binding of NF-Y and the ubiquitous SP factors SP1, SP2 and SP3 genome-wide, allowing for comprehensive comparison of NF-Y and SP factor actions in the context of chromatin. Here, I attempt a synthesis of the earlier single-promoter type of analysis with the more recent genome-wide studies. In particular, I also discuss different modes of genomic interactions between SP factors and NF-Y that have emerged recently, and identify a key technical issue, which needs to be taken into account in a critical evaluation of genome-wide studies.

PMID- 27697430 TI - Defining imaging biomarker cut points for brain aging and Alzheimer's disease. AB - INTRODUCTION: Our goal was to develop cut points for amyloid positron emission tomography (PET), tau PET, flouro-deoxyglucose (FDG) PET, and MRI cortical thickness. METHODS: We examined five methods for determining cut points. RESULTS: The reliable worsening method produced a cut point only for amyloid PET. The specificity, sensitivity, and accuracy of cognitively impaired versus young clinically normal (CN) methods labeled the most people abnormal and all gave similar cut points for tau PET, FDG PET, and cortical thickness. Cut points defined using the accuracy of cognitively impaired versus age-matched CN method labeled fewer people abnormal. DISCUSSION: In the future, we will use a single cut point for amyloid PET (standardized uptake value ratio, 1.42; centiloid, 19) based on the reliable worsening cut point method. We will base lenient cut points for tau PET, FDG PET, and cortical thickness on the accuracy of cognitively impaired versus young CN method and base conservative cut points on the accuracy of cognitively impaired versus age-matched CN method. PMID- 27697432 TI - Antifungal activities of tacrolimus in combination with antifungal agents against fluconazole-susceptible and fluconazole-resistant Trichosporon asahii isolates. AB - The antifungal activity of tacrolimus in combination with antifungal agents against different fungal species has been previously reported. Here we report the in vitro interactions between tacrolimus and amphotericin B, fluconazole, itraconazole, and caspofungin against 30 clinical isolates of both fluconazole susceptible and fluconazole-resistant Trichosporon asahii. For these analyses, we used the broth microdilution method based on the M27-A3 technique and checkerboard microdilution method. Tacrolimus showed no activity against T. asahii strains (minimal inhibitory concentrations, MICs>64.0MUgmL-1). However, a larger synergistic interaction was observed by the combinations tacrolimus+amphotericin B (96.67%) and tacrolimus+caspofungin (73.33%) against fluconazole-susceptible isolates. Combinations with azole antifungal agents resulted in low rates of synergism for this group (fluconazole+tacrolimus=40% and itraconazole+tacrolimus=10%). Antagonistic interactions were not observed. For the fluconazole-resistant T. asahii group, all tested combinations showed indifferent interactions. The synergism showed against fluconazole-susceptible T. asahii isolates suggests that the potential antifungal activity of tacrolimus deserves in vivo experimental investigation, notably, the combination of tacrolimus with amphotericin B or caspofungin. PMID- 27697433 TI - Increased levels of soluble triggering receptor expressed on myeloid cells-1 in cerebrospinal fluid of subarachnoid hemorrhage patients. AB - Triggering receptor expressed on myeloid cells-1 (TREM-1) has been highlighted as a key amplifier of inflammatory response in various diseases. To determine the contribution of TREM-1 in the inflammatory cascade after subarachnoid hemorrhage (SAH), concentrations of soluble TREM-1 (sTREM-1) in cerebrospinal fluid (CSF) from 30 SAH patients and 9 healthy volunteers were measured by enzyme-linked immunosorbent assay. It was shown that the CSF sTREM-1 levels of SAH patients increased significantly than that of the volunteers (P<0.05). Interestingly, the levels were up-regulated dynamically over time with an early increase within 2days and a late peak at day 6 after SAH onset. In addition, it was found that the early sTREM-1 levels (within 3days post-SAH) were negatively correlated with Glasgow Coma Scale (r=-0.550, P=0.022) and positively correlated with the Hunt and Hess scale (r=0.603, P=0.010) respectively conducted on admission, also the early sTREM-1 levels were negatively correlated with Glasgow Outcome Scale (r= 0.505, P=0.039) and positively correlated with modified Rankin Scale (r=0.557, P=0.020) respectively conducted one month after SAH. Altogether, this is the first study showing CSF sTREM-1 dynamics in SAH patients, and exploring the correlations of early CSF sTREM-1 levels to patients' severity and prognosis, which suggests that TREM-1 may play an important role in the inflammatory cascade after SAH and act as a monitoring biomarker facilitated to assess the severity and prognosis of SAH patients. PMID- 27697435 TI - Distinct inflammatory responses differentiate cerebral infarct from transient ischaemic attack. AB - We previously reported on a 26-year-old patient who presented early during a large and eventually fatal cerebral infarct. Microarray analysis of blood samples from this patient demonstrated initially up-regulated and subsequently down regulated Granzyme B (GzmB) expression, along with progressive up-regulation of genes for S100 calcium binding protein A12 (S100A12) and matrix metalloproteinase 9 (MMP-9). To confirm these findings, we investigated these parameters in patients with suspected stroke presenting within 6h of symptom onset to a single centre. Blood samples were taken at enrolment, then 1h, 3h and 24h post-enrolment for the examination of cellular, protein and genetic changes. Patients with subsequently confirmed ischaemic (n=18) or haemorrhagic stroke (n=11) showed increased intracellular concentrations of GzmB in all cell populations investigated (CD8+, CD8- and Natural Killer [NK] cells). Infarct patients, however, demonstrated significantly reduced GzmB gene expression and increased circulating MMP-9 and S100A12 levels in contrast to transient ischaemic attack (TIA) patients or healthy controls. Furthermore, a pronounced neutrophilia was noted in the infarct and haemorrhage groups, while TIA patients (n=9) reflected healthy controls (n=10). These findings suggest a spectrum of immune response during stroke. TIA showed few immunological changes in comparison to infarct and haemorrhage, which demonstrated inhibition of GzmB production and a rise in neutrophil numbers and neutrophil-associated mediators. This implies a greater role of the innate immune system. These markers may provide novel targets for inhibition and reduction of secondary injury. PMID- 27697436 TI - Evidence supporting idarucizumab for the reversal of dabigatran. AB - Idarucizumab is a monoclonal antibody fragment specifically targeted to dabigatran. It has demonstrated prompt and durable reversal of the anticoagulant effects of dabigatran in animal studies and phase 1 studies of young, elderly, and renally impaired volunteers. Although elective invasive procedures and most bleeding complications in dabigatran-treated patients can be managed by temporarily stopping dabigatran therapy and using supportive measures, there are rare clinical situations that require urgent reversal of the anticoagulant effect of dabigatran. The effectiveness and safety of 5 g of intravenous idarucizumab is being investigated in a prospective, open-label, single-cohort study in patients with serious bleeding or in those requiring an urgent procedure. In an interim analysis of the first 90 participants, idarucizumab rapidly and completely reversed the anticoagulant activity of dabigatran in 88%-98% of participants, and there were no safety concerns, with no deaths or serious adverse events being attributable to idarucizumab. Supported by these interim results, idarucizumab has been approved in the United States and the European Union for use when reversal of the anticoagulant effects of dabigatran is needed for emergency surgery/urgent procedures or in patients with life-threatening or uncontrolled bleeding. Clinical use of idarucizumab should follow the same processes as patient enrollment in this study, which is projected to be completed in 2016. The outcomes achieved with this specific reversal agent are likely to be of continued interest to treating physicians. PMID- 27697434 TI - Elevation of oxidative stress indicators in a pilot study of plasma following traumatic brain injury. AB - Traumatic brain injury (TBI) encompasses a broad range of injury mechanisms and severity. A detailed determination of TBI severity can be a complex challenge, with current clinical tools sometimes insufficient to tailor a clinical response to a spectrum of patient needs. Blood biomarkers of TBI may supplement clinical assessments but currently available biomarkers have limited sensitivity and specificity. While oxidative stress is known to feature in damage mechanisms following TBI, investigation of blood biomarkers of oxidative stress has been limited. This exploratory pilot study of a subset of 18 trauma patients with TBI of varying severity, quantifies circulating concentrations of the structural damage indicators S100b, and myelin basic protein (MBP), and the biomarkers of oxidative stress hydroxynonenal (HNE), malondialdehyde (MDA), carboxy-methyl lysine (CML), and 8-hydroxy-2'-deoxy-guanosine (8-OHDG). Significant increases in circulating S100b, MBP, and HNE were observed in TBI patient samples compared to 8 uninjured controls, and there was a significant decrease in CML. This small exploratory study supports the current literature on S100b and MBP elevation in TBI, and reveals potential for the use of peripheral oxidative stress markers to assist in determination of TBI severity. Further investigation is required to validate results and confirm trends. PMID- 27697437 TI - Introduction to direct oral anticoagulants and rationale for specific reversal agents. PMID- 27697438 TI - Idarucizumab and factor Xa reversal agents: role in hospital guidelines and protocols. AB - As expected with all antithrombotic agents, there is a risk of bleeding complications in patients receiving direct oral anticoagulants (DOACs) because of the DOAC itself, acute trauma, invasive procedures, or underlying comorbidities. For many bleeding events, a prudent course of action will be to withdraw the DOAC, then "wait and support" the patient, with the expectation that the bleeding event should resolve with time. Likewise, DOAC therapy may be interrupted ahead of a planned procedure, the stopping time being dependent on the agent involved and the patient's renal function. However, urgent reversal of anticoagulation is required in patients with serious or life-threatening bleeding or in those requiring urgent surgery or procedures. Novel specific reversal agents, either under development or recently approved, will need to be incorporated into local anticoagulation reversal protocols. For dabigatran-treated patients, idarucizumab recently has been approved for clinical use in cases of life-threatening or uncontrolled bleeding or when patients require emergency surgery or urgent procedures, both associated with a high risk of bleeding. As clinical experience with individual specific reversal agents grows, their roles in managing major bleeding events in DOAC-treated patients will become better defined. Future research, as well as ongoing use of idarucizumab, should help establish when it is appropriate to re-dose with idarucizumab, coadminister with prothrombin complex concentrates, or re-initiate DOAC after idarucizumab use. Ongoing trials should help identify the appropriate doses and expected durations of effect for andexanet alfa and ciraparantag, which are likely to vary depending on the individual oral anticoagulants. PMID- 27697439 TI - Bleeding with direct oral anticoagulants vs warfarin: clinical experience. AB - The risk of bleeding in the setting of anticoagulant therapy continues to be re evaluated following the introduction of a new generation of direct oral anticoagulants (DOACs). Interruption of DOAC therapy and supportive care may be sufficient for the management of patients who present with mild or moderate bleeding, but in those with life-threatening bleeding, a specific reversal agent is desirable. We review the phase 3 clinical studies of dabigatran, rivaroxaban, apixaban, and edoxaban in patients with nonvalvular atrial fibrillation, in the context of bleeding risk and management. PMID- 27697440 TI - Re-initiation of dabigatran and direct factor Xa antagonists after a major bleed. AB - Direct oral anticoagulants (DOACs) are a relatively recent addition to the oral anticoagulant armamentarium, and provide an alternative to the use of vitamin K antagonists such as warfarin. Regardless of the type of agent used, bleeding is the major complication of anticoagulant therapy. The decision to restart oral anticoagulation following a major hemorrhage in a previously anticoagulated patient is supported largely by retrospective studies rather than randomized clinical trials (mostly with vitamin K antagonists), and remains an issue of individualized clinical assessment: the patient's risk of thromboembolism must be balanced with the risk of recurrent major bleeding. This review provides guidance for clinicians regarding if and when a patient should be re-initiated on DOAC therapy following a major hemorrhage, based on the existing evidence. PMID- 27697441 TI - Safety of direct oral anticoagulants: insights from postmarketing studies. AB - Direct oral anticoagulants (DOACs) have been marketed in the United States since 2010. While numerous large-scale prospective phase 3 outcomes studies have documented the effectiveness of DOACs for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation, the primary safety concern with all of these drugs-as it is with the more established oral anticoagulant warfarin-is the risk of major bleeding. Postmarketing surveillance studies (PMSS) provide the opportunity to evaluate the safety of these recently approved drugs across a spectrum of patients that may be broader than those included in randomized controlled trials. This review will summarize the safety findings of numerous recently performed, large-scale PMSS evaluations, and consider the currently available evidence regarding the risks for bleeding in patients treated with DOACs, in order to give providers and patients additional evidence regarding the safety of DOACs. PMID- 27697442 TI - Discontinuation and management of direct-acting anticoagulants for emergency procedures. AB - Patients taking direct oral anticoagulants (DOACs) who then need an emergency invasive procedure require specialized management strategies. Appropriate patient evaluation includes assessment of the current anticoagulation state, including timing of the last dose. DOACs require particular coagulation assays to measure anticoagulation levels accurately, although standard coagulation screening tests may provide qualitative guidance. Specialty societies have endorsed general recommendations for patient management to promote hemostasis in anticoagulated patients requiring surgery or other invasive procedures. These include general stopping rules (such as >=24 hours for low-risk procedures and >=48 hours for high-risk surgery with normal renal function) for elective procedures. Bridging therapy when oral anticoagulant treatment is interrupted has recently been questioned, depending on the clinical scenario. Novel agents for the reversal of DOAC-induced anticoagulation have recently been developed. Idarucizumab, a humanized monoclonal antibody fragment that selectively binds dabigatran, was recently approved for clinical use in patients with life-threatening or uncontrolled bleeding, and for patients requiring emergency interventions. Idarucizumab can streamline the pre- and periprocedural anticoagulation management of dabigatran-treated patients, as it provides fast, complete, and sustainable reversibility. Andexanet alfa is an inactive, decoy factor Xa (FXa) molecule that binds FXa inhibitors, and ciraparantag is a synthetic molecule designed to bind fractionated and unfractionated heparins, and each of the currently approved DOACs. As clinical development of the additional anti-FXa specific anticoagulant reversal agents proceeds, the respective role of each in the management of emergency bleeding events and invasive procedures will be better defined, and it is hoped they will make important contributions to patient care. PMID- 27697443 TI - Preclinical and clinical data for factor Xa and "universal" reversal agents. AB - Oral Factor Xa (FXa) inhibitors, a growing class of direct-acting anticoagulants, are frequently used to prevent stroke and systemic embolism in patients with atrial fibrillation and to prevent and treat venous thromboembolism. These drugs reduce the risk of clotting at the expense of increasing the risk of bleeding, and currently they have no specific reversal agent. However, andexanet alfa, a recombinant modified FXa decoy molecule, is in a late-phase clinical trial in bleeding patients, and ciraparantag, a small molecule that appears to reverse many anticoagulants including the FXa inhibitors, is in development. This review summarizes the published data to date on both drugs, which have the potential to change the management approach to patients with FXa inhibitoreassociated major hemorrhage. PMID- 27697444 TI - Probiotic Treatment with a Gut Symbiont Leads to Parasite Susceptibility in Honey Bees. AB - Gut symbionts are critical for host health and as such might be used as probiotics.

PMID- 27697445 TI - Diagnostic accuracy of probe-based confocal laser endomicroscopy in Lugol unstained esophageal superficial lesions of patients with head and neck cancer. AB - BACKGROUND AND AIMS: Surveillance programs of patients with head and neck cancer (HNC) detect synchronous or metachronous esophageal squamous cell carcinoma (ESCC) in up to 15% of patients. Noninvasive, probe-based confocal laser endomicroscopy (pCLE) technique may improve the diagnosis allowing acquisition of high-resolution in vivo images at the cellular and microvascular levels. The aim of this study was to evaluate the accuracy of pCLE for the differential diagnosis of nonneoplastic and neoplastic Lugol-unstained esophageal lesions in patients with HNC. METHODS: Twenty-seven patients with HNC who exhibited Lugol-unstained esophageal lesions at surveillance endoscopy were prospectively included for pCLE. Diagnostic pCLE was followed by subsequent biopsies or endoscopic resection of suspected lesions. A senior pathologist was blinded to the pCLE results. RESULTS: Patients mean age was 59 years (SD = 8.8) and 70.4% were men. All patients were smokers, and 22 patients (81.5%) had a history of alcohol consumption. The locations of HNC were oral cavity (n = 13), larynx (n = 10), and pharynx (n = 4). Thirty-seven lesions in 27 patients were studied. The final diagnoses were ESCC in 17 patients and benign lesions in 20 patients. Sensitivity, specificity, and accuracy of pCLE for the histologic diagnosis of ESCC in patients with HNC were 94.1%, 90.0%, and 91.9%, respectively. CONCLUSIONS: First, pCLE is highly accurate for real-time histology of Lugol unstained esophageal lesions in patients with HNC. Second, pCLE may alter the management of patients under surveillance for ESCC, guiding biopsies and endoscopic resection, avoiding further diagnostic workup or therapy of benign lesions. PMID- 27697446 TI - Coadministration of puerarin (low dose) and zinc attenuates bone loss and suppresses bone marrow adiposity in ovariectomized rats. AB - AIMS: Puerarin is a phytoestrogen that shows osteogenic effects. Meanwhile, zinc stimulates bone formation and inhibits bone resorption. The study aims to investigate the effects of coadministration of puerarin (low dose) and zinc on bone formation in ovariectomized rats. MATERIALS AND METHODS: Co-administration or use alone of puerarin (low dose) and/or zinc were gavaged in OVX rats. The estrogen-like effects were detected by the uterus weight, the histologic observation and the IGF-1 protein expression. The osteogenic effects were determined by bone histomorphometric and mechanical parameters, osteogenic and adipogenic blood markers, and so on. KEY FINDINGS: The results showed that oral administration of puerarin (low dose) plus zinc didn't significantly increase uterus weight. The glandular epithelial of endometrium had no proliferation and no protein expression of IGF-1. Moreover, co-administration attenuated bone loss and biomechanical decrease more than single use of puerarin or zinc (p<0.05). Next, combined administration of puerarin and zinc promoted the serological level of osteocalcin, bone marrow stromal cell (BMSC) proliferation, and the expression of alkaline phosphatase (ALP), and suppressed the serological level of adiponectin and adiposity in bone marrow (BM). SIGNIFICANCE: In conclusion, co administrated puerarin (low dose) and zinc can partially reverse OVX-induced bone loss and suppress the adiposity of BM in rats, which shed light on the potential use of puerarin and zinc in the treatment of osteoporosis. PMID- 27697448 TI - Endothelial nitric oxide synthase gene polymorphisms are associated with cardiovascular risks in prehypertensives. AB - Though endothelial nitric oxide synthase (eNOS) gene polymorphism is documented in the causation of hypertension, its role in prehypertension has not been investigated. The present study was conducted in 172 subjects divided into prehypertensives (n = 57) and normotensives (n = 115). Cardiovascular (CV) parameters including baroreflex sensitivity (BRS) by continuous BP variability assessment and sympathovagal imbalance (SVI) by heart rate variability analysis were recorded. Biochemical parameters for insulin resistance (homeostatic model for assessment of insulin resistance), oxidative stress, lipid risk factors, renin, and inflammatory parameters were measured. Genotyping for eNOS polymorphisms rs1799983 (298G>T) and rs2070744 (-786T>C) was performed by polymerase chain reaction-restriction fragment length polymorphism method. Multiple regression analysis was done to assess the association between SVI and metabolic markers, and multivariate logistic regression was done to determine the prediction of prehypertension status by genotype, BRS, and ratio of low-frequency to high-frequency in these subjects. The BP variability, heart rate variability, and biochemical parameters were significantly altered in prehypertensives. The eNOS polymorphisms were found to be associated with prehypertension. BRS, the marker of SVI, was significantly associated with BP, homeostatic model for assessment of insulin resistance, and tumor necrosis factor alpha in 298GG genotype of prehypertensive population. The eNOS gene polymorphisms appear to be associated with prehypertension. 298G>T and -786T>C contribute to SVI in young prehypertensives attributed by insulin resistance and inflammation. The CV risks were associated with prehypertension status in prehypertensives expressing both 298GG and -786TT genotypes. Association of CV risks with SVI appears to be stronger in prehypertensives expressing GG genotype. PMID- 27697447 TI - The association between Self-Reported Medication Adherence scores and systolic blood pressure control: a SPRINT baseline data study. AB - We examined baseline data from the Systolic Blood Pressure Intervention Trial (SPRINT) to investigate whether medication adherence, measured by the 8-item Morisky Medication Adherence Scale (MMAS-8), was associated with systolic blood pressure (SBP) and whether MMAS-8 score and number of antihypertensive medications interacted in influencing SBP. A total of 8435 SPRINT participants were included: 21.2% had low adherence (MMAS-8: <6); 40.0% had medium adherence (6 to <8); and 38.8% had high adherence (8). SBP was <140 mm Hg in 54.6%; 140-160 mm Hg in 36.6%; and >160 mm Hg in 8.8%. In multivariable regression, medium vs. low adherence weakly associated with lower SBP (odds ratio: 1.17; confidence interval: 1.04, 1.31). SPRINT eligibility criteria should be considered when interpreting results. Efforts to understand and enhance adherence are crucial to improve population health, and using self-report instruments might be considered for predicting treatment adherence and response in future efficacy trials and for identifying patients for adherence support in clinical practice. PMID- 27697449 TI - A Longitudinal Investigation of Anxiety and Depressive Symptomatology and Exercise Behaviour Among Adults With Type 2 Diabetes Mellitus. AB - OBJECTIVES: Evidence suggests that symptoms of depression and anxiety predict lower exercise behaviour and, inversely, that less exercise predicts higher symptomatology. The present longitudinal study examined this reciprocal association in adults with type 2 diabetes mellitus. We predicted that symptoms of anxiety or depression would intensify over time as a consequence of lower exercise frequency and, similarly, that exercise frequency would decrease as a consequence of greater symptoms of anxiety or depression. METHODS: We studied 1691 adults with type 2 diabetes who provided baseline measures in 2011 and 2 subsequent annual assessments (Follow-up 1 and Follow-up 2). Symptoms of depression and anxiety were measured using the Patient Health Questionnaire-9 and the Generalized Anxiety Disorder-7, respectively. A single item assessed exercise frequency in the past month (in days). RESULTS: Separate 3-wave cross-lagged path models for symptoms of anxiety and depression tested the reciprocal associations. Contrary to our hypotheses, the reciprocal associations were not supported and, by extension, the predicted secondary associations were not tested. In sum, only depressive symptoms negatively predicted subsequent exercise frequency (Follow-up 1 and Follow-up 2). CONCLUSIONS: Symptoms of depression were prospectively associated with lower exercise frequency, which is consistent with evidence from population-based studies that identify depressive symptoms as a barrier to exercise participation.

AB - The effect of being overweight on seminal variables was assesed in 165 fertile men. Participants were divided into three groups: fertile men with normal body mass index (BMI) (18.5-24.9 kg/m2), fertile overweight men (BMI 25-29.9 kg/m2) and fertile obese men (BMI >30 kg/m2). Medical history was taken, a clinical examination conducted. Semen analysis was undertaken and BMI measured. Seminal reactive oxygen species (ROS) was estimated by chemiluminescent assay, sperm vitality by the hypo-osmotic swelling test and sperm DNA fragmentation by propidium iodide staining with flowcytometry. Fertile obese men had significantly lower sperm concentration, progressive sperm motility and sperm normal morphology, with significantly higher seminal ROS and sperm DNA fragmentation compared with fertile normal-weight men and overweight men (all P < 0.05). BMI was negatively correlated with sperm concentration (r = -0.091; P = 0.014), progressive sperm motility (r = -0.697; P = 0.001), normal sperm morphology (r = 0.510; P = 0.001), sperm vitality (r = -0.586; P = 0.001), but positively correlated with sperm DNA fragmentation percentage (r = 0.799; P = 0.001) and seminal ROS (r = 0.673; P = 0.001). Increased BMI was found to affect semen parameters negatively even in fertile men. PMID- 27697452 TI - Identification of a novel aviadenovirus, designated pigeon adenovirus 2 in domestic pigeons (Columba livia). AB - The young pigeon disease syndrome (YPDS) affects mainly young pigeons of less than one year of age and leads to crop stasis, vomitus, diarrhea, anorexia and occasionally death. This disease is internationally a major health problem because of its seasonal appearance during competitions such as homing pigeon races or exhibitions of ornamental birds. While the etiology of YPDS is still unclear, adenoviruses are frequently discussed as potential causative agents. Electron microscopy of feces from a YPDS outbreak revealed massive shedding of adenovirus-like particles. Whole genome sequencing of this sample identified a novel adenovirus tentatively named pigeon adenovirus 2 (PiAdV-2). Phylogenetic and comparative genome analysis suggest PiAdV-2 to belong to a new species within the genus Aviadenovirus, for which we propose the name Pigeon aviadenovirus B. The PiAdV-2 genome shares 54.9% nucleotide sequence identity with pigeon adenovirus 1 (PiAdV-1). In a screening of further YPDS-affected flocks two variants of PiAdV-2 (variant A and B) were detected which shared 97.6% nucleotide identity of partial polymerase sequences, but only 79.7% nucleotide identity of partial hexon sequences. The distribution of both PiAdV-2 variants was further investigated in fecal samples collected between 2008 and 2015 from healthy or YPDS-affected racing pigeons of different lofts. Independent of their health status, approximately 20% of young and 13% of adult pigeon flocks harbored PiAdV 2 variants. Birds were free of PiAdV-1 or other aviadenoviruses as determined by PCRs targeting the aviadenovirus polymerase or the PiAdV-1 fiber gene, respectively. In conclusion, there is no indication of a correlation between YPDS outbreaks and the presence of PiAdV-2 or other aviadenoviruses, arguing against an causative role in this disease complex. PMID- 27697453 TI - The functional analysis of distinct tospovirus movement proteins (NSM) reveals different capabilities in tubule formation, cell-to-cell and systemic virus movement among the tospovirus species. AB - The lack of infectious tospovirus clones to address reverse genetic experiments has compromised the functional analysis of viral proteins. In the present study we have performed a functional analysis of the movement proteins (NSM) of four tospovirus species Bean necrotic mosaic virus (BeNMV), Chrysanthemum stem necrosis virus (CSNV), Tomato chlorotic spot virus (TCSV) and Tomato spotted wilt virus (TSWV), which differ biologically and molecularly, by using the Alfalfa mosaic virus (AMV) model system. All NSM proteins were competent to: i) support the cell-to-cell and systemic transport of AMV, ii) generate tubular structures on infected protoplast and iii) transport only virus particles. However, the NSM of BeNMV (one of the most phylogenetically distant species) was very inefficient to support the systemic transport. Deletion assays revealed that the C-terminal region of the BeNMV NSM, but not that of the CSNV, TCSV and TSWV NSM proteins, was dispensable for cell-to-cell transport, and that all the non-functional C terminal NSM mutants were unable to generate tubular structures. Bimolecular fluorescence complementation analysis revealed that the C-terminus of the BeNMV NSM was not required for the interaction with the cognate nucleocapsid protein, showing a different protein organization when compared with other movement proteins of the '30K family'. Overall, our results revealed clearly differences in functional aspects among movement proteins from divergent tospovirus species that have a distinct biological behavior. PMID- 27697454 TI - Nerve stress during reverse total shoulder arthroplasty: a cadaveric study. AB - BACKGROUND: Neurologic lesions are relatively common after total shoulder arthroplasty. These injuries are mostly due to traction. We aimed to identify the arm manipulations and steps during reverse total shoulder arthroplasty (RTSA) that affect nerve stress. METHODS: Stress was measured in 10 shoulders of 5 cadavers by use of a tensiometer on each nerve from the brachial plexus, with shoulders in different arm positions and during different surgical steps of RTSA. RESULTS: When we studied shoulder position without prostheses, relative to the neutral position, internal rotation increased stress on the radial and axillary nerves and external rotation increased stress on the musculocutaneous, median, and ulnar nerves. Extension was correlated with increase in stress on all nerves. Abduction was correlated with increase in stress for the radial nerve. We identified 2 high-risk steps during RTSA: humeral exposition, particularly when the shoulder was in a position of more extension, and glenoid exposition. The thickness of polyethylene humeral cups used was associated with increased nerve stress in all but the ulnar nerve. CONCLUSION: During humeral preparation, the surgeon must be careful to limit shoulder extension. Care must be taken during exposure of the glenoid. Extreme rotation and oversized implants should be avoided to minimize stretch-induced neuropathies. PMID- 27697455 TI - Pectoralis major tendon tears: functional outcomes and return to sport in a consecutive series of 40 athletes. AB - BACKGROUND: There are limited data on the outcomes of surgically repaired pectoralis major tendon (PMT) tears. The purpose of this study was to report the functional outcomes, return to sport, and second surgery rates in a consecutive series of PMT tears. METHODS: Forty patients with acutely repaired PMT tears were retrospectively identified. Follow-up was conducted with functional outcome scores and adduction strength testing at final follow-up. Return to sport and incidence of subsequent surgery were also recorded. RESULTS: The average age of the patients was 34.4 years (range, 23-59 years). Average follow-up was 2.5 years (range, 2-7.0 years). Twenty-three injuries (58%) occurred in the nondominant extremity. Bench press (n = 26) and contact sport participation (n = 14) were the most common mechanisms. Postoperative Single Assessment Numeric Evaluation scores averaged 93.6 (range, 62-100), with patient satisfaction of 9.6 of 10 (range, 6 10). All athletes returned to preinjury level of function approximately 5.5 months postoperatively (range, 4.5-6.5 months); 23.1% and 2.6% described mild or moderate difficulties with sport participation. Isokinetic strength evaluation revealed an average decrease of 9.9% (range, -18% to 41%). Application of the Bak criteria revealed 37% excellent, 26% good, and 37% fair outcomes, with most in the fair group reporting cosmetic concerns. Removing cosmesis, 46% scored excellent, 37% good, and only 17% fair. Three athletes required a second surgical procedure (7.5%). CONCLUSIONS: Surgical repair of PMT tears resulted in high patient satisfaction, with excellent restoration of function and adduction strength, early return to sport, and few reoperations, albeit with the potential for mild cosmetic concerns. PMID- 27697456 TI - Prenatal infection leads to ASD-like behavior and altered synaptic pruning in the mouse offspring. AB - Environmental challenges to the maternal immune system during pregnancy have been associated with an increase in the frequency of neurodevelopmental disorders such as Autism Spectrum Disorders (ASD) appearing in the offspring. Microglia, the brain's resident immune-cells, are now known to be critically involved in normal brain development, shaping connections between neurons by pruning superfluous synaptic spines. Our aim was to investigate whether maternal infection during critical stages of gestation compromises the role of microglia in sculpting neuronal circuits. Using a mouse model of maternal immune activation (MIA) induced by bacterial Lipopolysaccharide (LPS), we assayed the offspring's behavior during postnatal development. Additionally, we quantified spines within the offspring's brain and assessed alterations in some molecular signals involved in pruning. LPS-induced MIA led to behavioral changes relevant to ASD in the offspring in the absence of gross neurological problems. Prenatal LPS resulted in a significant increase in the number of spines in the granule cells of the dentate gyrus, as well as a reduction in hippocampal expression of the fractalkine microglial receptor (CX3CR1), involved in mediating the pruning process in the offspring. Interestingly, these changes were only noted in the male progeny of the LPS challenged dams. These results provide an early indicator that microglial function is altered in the brain of offspring from immune challenged mothers and that the effects in the brain appear to be specific along sex lines. PMID- 27697457 TI - Aryl hydrocarbon receptor-ligand axis mediates pulmonary fibroblast migration and differentiation through increased arachidonic acid metabolism. AB - Pulmonary fibroblast migration and differentiation are critical events in fibrogenesis; meanwhile, fibrosis characterizes the pathology of many respiratory diseases. The role of aryl hydrocarbon receptor (AhR), a unique cellular chemical sensor, has been suggested in tissue fibrosis, but the mechanisms through which the AhR-ligand axis influences the fibrotic process remain undefined. In this study, the potential impact of the AhR-ligand axis on pulmonary fibroblast migration and differentiation was analyzed using human primary lung fibroblasts HFL-1 and CCL-202 cells. Boyden chamber-based cell migration assay showed that activated AhR in HFL-1cells significantly enhanced cell migration in response to 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD), and a known AhR antagonist, CH223191, inhibited its migratory activity. Furthermore, the calcium mobilization and subsequent upregulated expression of arachidonic acid metabolizing enzymes, including cyclooxygenase2 (COX-2) and 5-lipoxygenase (5-LOX), were observed in TCDD-treated HFL-1 cells, concomitant with elevated levels of prostaglandin E2 (PGE2) and leukotriene B4 (LTB4) secretion. Also, significantly increased expression of alpha-smooth muscle actin alpha-SMA), a fibroblast differentiation marker, was also noted in TCDD-treated HFL-1 cells (p<0.05), resulting in a dynamic change in cytoskeleton protein levels and an increase in the nuclear translocation of the myocardin-related transcription factor. Moreover, the enhanced levels of alpha-SMA expression and fibroblast migration induced by TCDD, PGE2 and LTB4 were abrogated by selective inhibitors for COX-2 and 5-LOX. Knockdown of AhR by siRNA completely diminished intracellular calcium uptake and reduced alpha-SMA protein verified by promoter-reporter assays and chromatin immunoprecipitation. Taken together, our results suggested the importance of the AhR-ligand axis in fibroblast migration and differentiation through its capacity in enhancing arachidonic acid metabolism. PMID- 27697458 TI - Real-time EEG artifact correction during fMRI using ICA. AB - BACKGROUND: Simultaneous acquisition of EEG and fMRI data results in EEG signal contamination by imaging (MR) and ballistocardiogram (BCG) artifacts. Artifact correction of EEG data for real-time applications, such as neurofeedback studies, is the subject of ongoing research. To date, average artifact subtraction (AAS) is the most widespread real-time method used to partially remove BCG and imaging artifacts without requiring extra hardware equipment; no alternative software only real time methods for removing EEG artifacts are available. NEW METHODS: We introduce a novel, improved approach for real-time EEG artifact correction during fMRI (rtICA). The rtICA is based on real time independent component analysis (ICA) and it is employed following the AAS method. The rtICA was implemented and validated during EEG and fMRI experiments on healthy subjects. RESULTS: Our results demonstrate that the rtICA employed after the rtAAS can obtain 98.4% success in detection of eye blinks, 4.4 times larger INPS reductions compared to RecView-corrected data, and effectively reduce motion artifacts, as well as imaging and muscle artifacts, in real time on six healthy subjects. COMPARISON WITH EXISTING METHODS: We compared our real-time artifact reduction results with the rtAAS and various offline methods using multiple evaluation metrics, including power analysis. Importantly, the rtICA does not affect brain neuronal signals as reflected in EEG bands of interest, including the alpha band. CONCLUSIONS: A novel real-time ICA method was proposed for improving the EEG quality signal recorded during fMRI acquisition. The results show substantial reduction of different types of artifacts using real-time ICA method. PMID- 27697459 TI - Hematospermia as a Rare Form of Presentation of Zinner Syndrome. AB - A 17-year-old adolescent boy was referred to the urology department of our institution for hematospermia after initiation of sexual relationship. A magnetic resonance imaging scan showed giant dilation of a multicystic left seminal vesicle with left renal agenesis. These findings are typical of the Zinner syndrome. In 70%-80% of the cases when renal agenesis is found, there is an ipsilateral cystic dilation of the seminal vesicle that in some cases may be associated with testicular ectopia or absence of the bladder trigone. The ejaculatory ducts, which are formed from the mesonephric system, are abnormally developed in these cases.

AB - OBJECTIVE: To investigate the association between urinary neurotrophin levels, maximum flow rate (Qmax) variation, and the appearance of urgency in women with stress urinary incontinence (SUI) after a midurethral sling (MUS) procedure. MATERIALS AND METHODS: Thirty-one women with SUI were treated with a MUS. One year later, the outcome of surgery and the onset of urgency were assessed. At baseline and 1-year follow-up, urine was collected to measure nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) concentration, and Qmax variation was calculated. Urine samples from healthy women (n = 20) without lower urinary tract symptoms and overactive bladder (OAB) wet patients (n = 32) were used as controls. Urinary neurotrophin levels were measured by enzyme-linked immunosorbent assay and normalized to creatinine concentration. RESULTS: At baseline, urinary levels of NGF and BDNF were similar between SUI and healthy women (NGF: 2.10 +/- 0.68 vs 1.99 +/- 1.05; BDNF: 1.99 +/- 0.71 vs 1.81 +/- 0.90), and significantly inferior to OAB wet patients (NGF: 2.10 +/- 0.68 vs 2.50 +/- 0.54, P < .05; BDNF: 1.99 +/- 0.71 vs 2.71 +/- 0.45, P < .05). After surgery, there was a significant increase of both neurotrophins (vs baseline, P < .05) to the values of OAB wet patients. Moreover, there was a significantly higher percentage increase of NGF in women with de novo urgency than in those without lower urinary tract symptoms (P = .019). A trend for a higher mean Qmax reduction in women with de novo urgency was also found (P = .085). CONCLUSION: These findings suggest that increased bladder outlet resistance after a MUS may play a key role in the rise of urinary neurotrophins, promoting sensitization of bladder primary afferents and causing de novo urgency in susceptible patients.

AB - A new generation of laminates and cementitious materials incorporate antimicrobial metals into domestic infrastructure. Conventional culturing approaches are unsuitable for assessing the inhibitory properties of these materials.

PMID- 27697462 TI - Biological chemistry of hydrogen sulfide and persulfides. AB - Hydrogen sulfide (H2S) has been traditionally considered to be a toxic molecule for mammals. However, it can be formed endogenously and exert physiological effects with potential health benefits. H2S can partition two-fold in biological membranes and traverse them rapidly, diffusing between compartments. H2S reactivity has similarities to that of thiols, although it is less nucleophilic than thiols and it can form different products. H2S can react with oxidants derived from the partial reduction of oxygen, but direct scavenging is unlikely to explain H2S protective actions. Important effects are exerted on mitochondria including the stimulation or the inhibition of the electron transport chain. Possible mechanisms for unleashing biological consequences are the reactions with metal centers and with thiol oxidation products. The reactions of H2S with disulfides (RSSR) and sulfenic acids (RSOH) lead to the formation of persulfides (RSSH). Persulfides have enhanced nucleophilicity with respect to the corresponding thiol, consistent with the alpha effect. Besides, the inner and outer sulfurs can both act as electrophiles. In this review, we describe the reactions of H2S with oxidized thiol products and the properties of the persulfides formed in the context of the chemical biology of H2S.

AB - Proteases have pivotal roles in the skin's outermost layer, the epidermis. In the stratum corneum, serine proteases from the kallikrein-related peptidase (KLK) family have been implicated in several key homeostatic processes, including desquamation. However, the precise contribution of specific KLKs to each process remains unclear. To address this, we used a chemical biology approach and designed selective substrates and inhibitors for KLK7, the most abundant KLK protease in the stratum corneum. The resulting KLK7 inhibitor is the most potent inhibitor of this protease reported to date (Ki = 140 pM), and displays at least 1,000-fold selectivity over several proteases that are related by function (KLK5 and KLK14) or specificity (chymotrypsin). We then used substrates and inhibitors for KLK5, KLK7, and KLK14 to explore the activity of each protease in the stratum corneum using casein zymography and an ex vivo desquamation assay. These experiments provide the most detailed assessment of each KLK's contribution to corneocyte shedding in the plantar stratum corneum, revealing that inhibition of KLK7 alone is sufficient to block shedding, whereas KLK5 is also a major contributor. Collectively, these findings unveil chemical tools for studying KLK activity and demonstrate their potential for characterizing KLK biological functions in epidermal homeostasis. PMID- 27697465 TI - An "all 5 mm ports" technique for laparoscopic day-case anti-reflux surgery: A consecutive case series of 205 patients. AB - INTRODUCTION: Laparoscopic anti-reflux surgery is conventionally performed using two 10/12 mm ports. While laparoscopic procedures reduce post-operative pain, the use of larger ports invariably increases discomfort and affects cosmesis. We describe a new all 5 mm ports technique for laparoscopic anti-reflux surgery and present a review of our initial experience with this approach. METHODS: All patients undergoing laparoscopic fundoplication over a 35 month period from February 2013 under the care of a single surgeon were included. A Lind laparoscopic fundoplication was performed using an all 5 mm port technique. Data was recorded prospectively on patient demographics, operating surgeon, surgical time, date of discharge, readmissions, complications, need for re-intervention, and reasons for admission. RESULTS: Two hundred and five consecutive patients underwent laparoscopic fundoplication over the study period. The all 5 mm port technique was used in all cases, with conversion to a 12 mm port only once (0.49%). Median operating time was 52 min 185 (90.2%) patients were discharged as day cases. Increasing ASA grade and the presence of a hiatus hernia were associated with the need for overnight stay with admission required in 33% of patients with ASA 3, compared to 4% with ASA 1 (p = 0.001), and 29% of those with a hiatus hernia vs. 5% without (p < 0.001). No port-related complications occurred, and no patients developed recurrence of reflux symptoms. A single patient required mesh repair of a large hiatus hernia. CONCLUSION: The all 5 mm ports approach to laparoscopic anti-reflux surgery is a safe, efficient, and cost effective technique which facilitates same day discharge and minimises port related complications. National commissioning guidelines in the UK should target quality improvements in anti-reflux surgery based around day-case management. This would improve the service for these patients and culminate in cost savings for the NHS. PMID- 27697466 TI - Diacylglycerol kinases in cancer. AB - Diacylglycerol kinases (DGK) are a family of enzymes that catalyze the transformation of diacylglycerol into phosphatidic acid. In T lymphocytes, DGKalpha and zeta limit the activation of the PLCgamma/Ras/ERK axis, providing a critical checkpoint to inhibit T cell responses. Upregulation of these isoforms limits Ras activation, leading to hypo-responsive, anergic states similar to those caused by tumors. Recent studies have identified DGKalpha upregulation in tumor lymphocyte infiltrates, and cells from DGKalpha and zeta deficient mice show enhanced antitumor activity, suggesting that limitation of DAG based signals by DGK is used by tumors to evade immune attack. DGKalpha expression is low or even absent in other healthy cells like melanocytes, hepatocytes or neurons. Expression of this isoform, nevertheless is upregulated in melanoma, hepatocarcinoma and glioblastoma where DGKalpha contributes to the acquisition of tumor metastatic traits. A model thus emerges where tumor milieu fosters DGKalpha expression in tumors as well as in tumor infiltrating lymphocytes with opposite consequences. Here we review the mechanisms and targets that facilitate tumor "addiction" to DGKalpha, and discuss its relevance in the more advanced forms of cancer for tumor immune evasion. A better knowledge of this function offers a new perspective in the search of novel approaches to prevent inhibition of immune attack in cancer. Part of the failure in clinical progress may be attributed to the complexity of the tumor/T lymphocyte interaction. As they develop, tumors use a number of mechanisms to drive endogenous, tumor reactive T cells to a general state of hyporesponsiveness or anergy. A better knowledge of the molecular mechanisms that tumors use to trigger T cell anergic states will greatly help in the advance of immunotherapy research. PMID- 27697467 TI - Frozen section analysis of the pancreatic margin during pancreaticoduodenectomy for cancer: Does extending the resection to obtain a secondary R0 provide a survival benefit? Results of a systematic review. AB - BACKGROUND: During pancreaticoduodenectomy, frozen section pancreatic margin analysis permits to extend the resection in case of a positive margin, to achieve R0 margin. We aim to assess if patients having an R0 margin following the extension of the pancreatectomy after a positive frozen section (secondary R0) have different survival compared to those with R1 resection or primary R0 resection. METHODS: A systematic search was performed to identify all studies published up to March 2016 analyzing the survival of patients undergoing pancreaticoduodenectomy according to the results of frozen section pancreatic margin examination. Clinical effectiveness was synthetized through a narrative review with full tabulation of results. RESULTS: Four studies published between 2010 and 2014 were retrieved, including 2580 patients. A primary R0 resection was obtained in a percentage of patients ranging from 36.2% to 85.5%, whereas secondary R0 in 9.4%-57.8% of cases and R1 in 5.1%-9.2%. Median survival ranged from 19 to 29 months in R0 patients, from 11.9 to 18 months in secondary R0, and from 12 to 23 months in R1 patients. None of the study demonstrated a survival benefit of extending the resection to obtain a secondary R0 pancreatic margin. CONCLUSIONS: All the studies were concordant, and failed to demonstrate the survival benefit of additional pancreatic resection to obtain a secondary R0. However, inadequate surgery should not be advocated. This review suggests that re resection of the pancreatic margin may have limited impact on patients' survival. PMID- 27697468 TI - Muscle fatigue effects can be anticipated to reproduce a movement kinematics learned without fatigue. AB - Muscle fatigue modifies the gain between motor command magnitude and the mechanical muscular response. In other words, post-fatigue, central drives to the muscles must increase to maintain a particular submaximum mechanical output. In this study, we tested the hypothesis that this modified gain can be predicted by the central nervous system (CNS) during discrete ballistic movements. In two separate experiments, subjects were required to perform shoulder flexions in standing and sitting positions at submaximum target peak accelerations. They were assisted with visual feedback informing them on their performance after each trial. Shoulder flexions were performed before and after fatiguing protocols of the focal muscles. Acceleration signals, focal and postural muscle electromyograms (EMGs) were recorded. The results demonstrated that participants were able to reach with precision the target acceleration during the first movements post-fatigue at the cost of significant increase in focal motor command magnitude. Decreased variance of peak accelerations associated with increased focal command variability was observed post-fatigue. During the standing experiment, postural muscle EMGs revealed that anticipatory postural adjustments (APAs) scaled to focal movement acceleration post-fatigue. All these results support that fatigue effects are taken into account during movement planning. Indeed, given that no feedback could enable participants to adjust acceleration during movement, this capacity to anticipate fatigue effects is the exclusive result of feedforward processes. To account for this prediction capacity, we discuss the role of fatigue-related modifications in sensory inputs from the working muscles.

PMID- 27697470 TI - Milestone assessment of minimally invasive surgery in Pediatric Urology fellowship programs. AB - INTRODUCTION: Minimally invasive surgery has become an important aspect of Pediatric Urology fellowship training. In 2014, the Accreditation Council for Graduate Medical Education published the Pediatric Urology Milestone Project as a metric of fellow proficiency in multiple facets of training, including laparoscopic/robotic procedures. OBJECTIVE: The present study assessed trends in minimally invasive surgery training and utilization of the Milestones among recent Pediatric Urology fellows. STUDY DESIGN: Using an electronic survey instrument, Pediatric Urology fellowship program directors and fellows who completed their clinical year in 2015 were surveyed. Participants were queried regarding familiarity with the Milestone Project, utilization of the Milestones, robotic/laparoscopic case volume and training experience, and perceived competency with robotic/laparoscopic surgery at the start and end of the fellowship clinical year according to Milestone criteria. Responses were accepted between August and November 2015. RESULTS: Surveys were distributed via e-mail to 35 fellows and 30 program directors. Sixteen fellows (46%) and 14 (47%) program directors responded. All fellows reported some robotic experience prior to fellowship, and 69% performed >50 robotic/laparoscopic surgeries during residency. Fellow robotic/laparoscopic case volume varied: three had 1-10 cases (19%), four had 11-20 cases (25%), and nine had >20 cases (56%). Supplementary or robotic training modalities included simulation (9), animal models (6), surgical videos (7), and courses (2). Comparison of beginning and end of fellowship robotic/laparoscopic Milestone assessment (Summary Fig.) revealed scores of <3 in (10) 62% of fellow self-assessments and 10 (75%) of program director assessments. End of training Milestone scores >4 were seen in 12 (75%) of fellow self assessment and eight (57%) of program director assessments. DISCUSSION: An improvement in robotic/laparoscopic Milestone scores by both fellow self assessment and program director assessment was observed during the course of training; however, 43% of program directors rated their fellow below the graduation target of a Milestone score of 4. CONCLUSION: The best ways to teach minimally invasive surgery in fellowship training must be critically considered. PMID- 27697472 TI - Open Payments Database: Anti-Vascular Endothelial Growth Factor Agent Payments to Ophthalmologists. AB - PURPOSE: To analyze anti-vascular endothelial growth factor (anti-VEGF) agent associated industry payments to ophthalmologists using the Centers for Medicare and Medicaid Services (CMS) Open Payments and Provider Utilization and Payment data. DESIGN: Retrospective database review using 2 national databases. METHODS: Payments from 2013 to 2014 were analyzed by anti-VEGF agent, payment category, and dollar amount. Ranibizumab and aflibercept usage was correlated by performing log-ratio analysis. RESULTS: A total of 3207 ophthalmologists received 13 449 payments totaling $4 454 325 associated with ranibizumab and aflibercept. As 7% of ophthalmologists received 90% of payments, the Gini index was 0.92, demonstrating unequal distribution of payments. Consulting fees and speaker fees were associated with highest payment amounts to fewest providers. For 2383 providers (74%), greater than 90% of the anti-VEGF payments were associated exclusively with either ranibizumab or aflibercept. A total of 1382 ophthalmologists were matched in both databases. Providers receiving >90% of payments from ranibizumab were more likely to use ranibizumab, and those receiving >90% of payments from aflibercept were more likely to use aflibercept over bevacizumab as compared to those who received no payments. CONCLUSIONS: The distribution of all anti-VEGF payments is unequal. Ophthalmologists who received aflibercept or ranibizumab payments were more likely to receive the majority of payments from one source or the other, but not both. Those who received anti-VEGF payments were more likely to use ranibizumab or aflibercept, as compared to off label bevacizumab, than those who did not receive any payment. PMID- 27697471 TI - Utility of retrograde ureterocelogram in management of complex ureterocele. AB - INTRODUCTION: Symptomatic pediatric ureterocele has diverse manifestations, making evidence-based management impractical. Thus, detailed visualization of ureterocele anatomy prior to first surgical incision is invaluable. Retrograde ureterocelogram (RUC) is a simple, underutilized radiologic technique that can be performed during cystoscopy. This study sought to determine whether RUC changes surgical management by more accurately depicting the complex ureteral and ureterocele anatomy, compared with renal ultrasound (US) and voiding cystourethrography (VCUG). METHODS: Patients who underwent surgical management of ureterocele from 2003 to 2015 were identified; those who received concomitant fluoroscopic RUC were selected for the case series. Data collected included: demographics, pre-operative evaluation, surgical interventions, and outcomes. The RUC images were individually examined, and the anatomic impression compared with previous renal US and VCUG. Novel RUC findings not previously appreciated by the pre-operative evaluation were noted. The RUC was performed by cystoscopically inserting a needle into the ureterocele and injecting contrast retrograde. If indicated, simultaneous PIC (Positioning the Instillation of Contrast) cystography was performed. RESULTS: Of the 43 patients that underwent surgery for suspected ureterocele, 28 underwent cystoscopy + RUC (10 M: 18 F) at a median age of 4.6 months and median follow-up of 37.0 months. All patients had prior US, 25 had prior VCUG, and 20 had prior radionuclide studies. Ureteroceles were either duplex system (n = 21) or single system (n = 7); 17 were ectopic into the bladder neck or urethra; seven were intravesical; and four were pseudoureteroceles. Fourteen patients underwent concomitant transurethral incision of the ureterocele (TUIU); two were deferred for surgery; and 11 received concomitant definitive surgery (e.g., nephrectomy). The RUC illuminated novel aspects of the anatomy in 20 of the 28 patients. No adverse events occurred. Notably, in nine of the 28 children, significant observations from RUC prompted change to the pre-operative surgical plan. DISCUSSION: Retrograde ureterocelogram clearly revealed ureterocele ectopy, pseudoureterocele, ureterocele disproportion, and unsuspected duplex systems, making it a useful adjunct to standard US and VCUG studies. Retrograde ureterocelogram can also be used to fluoroscopically verify decompression of the ureterocele post incision, document severity of ureteral dilation, and teach residents about the great damage generated by ureterocele variations. Limitations of RUC included increasing radiation dose and overall cost. The study design was limited by its small size, retrospective approach, selection bias, and availability of RUC images. CONCLUSIONS: While not indicated in routine ureterocele management, intraoperative RUC further defined ureterocele anatomy in nearly all cases and yielded changes to the original surgical plan frequently enough to merit greater use in complex patients. PMID- 27697473 TI - Changes in Keratometric Values and Corneal High Order Aberrations After Hydrogel Inlay Implantation. AB - PURPOSE: We sought to analyze surgically induced refractive change (SIRC) and change in high-order aberration after Raindrop corneal inlay insertion (ReVision Optics, Lake Forest, CA), and assess the extent to which Raindrop corneal inlay insertion could correct presbyopia. DESIGN: Interventional case series. METHODS: Seventeen patients were included if they had a corneal thickness >=500 MUm and a stable manifest spherical equivalent refraction between 0.50 and +1.00 diopters (D). The Raindrop corneal inlay was implanted on the stromal bed of a femtosecond laser-assisted generated flap of nondominant eyes. Manifest refraction, corneal powers, and corneal high-order aberrations were measured preoperatively and at 3 and 12 months postoperatively. RESULTS: The SIRC by manifest refraction was 0.99 +/- 0.26 D. The changes derived from simulated keratometry (K), true net power, and equivalent K reading (EKR) at 1.0-4.0 mm were greater than the SIRC (all P < .01) while the change in EKR at 6.0 mm was less than the SIRC (P < .01). The changes in EKR 5.0 mm, automated K, and EKR 4.5 mm did not differ significantly from the SIRC (P = .81, .29, and .09, respectively), and the difference was the least for EKR 5.0 mm. In analysis of high-order aberrations, only spherical aberration showed statistically significant difference between preoperative and postoperative on both anterior cornea and total cornea (all P < .01). CONCLUSION: Raindrop corneal inlay corrects presbyopia via increasing negative spherical aberration. The equivalent K reading at 5.0 mm accurately reflected the SIRC, and would be applicable for intraocular power prediction before cataract surgery. PMID- 27697474 TI - Formation of an Intraretinal Fluid Barrier in Cavitary Optic Disc Maculopathy. AB - PURPOSE: Cavitary optic disc maculopathy develops when fluctuating pressure gradients along anomalous communications in the optic nerve head induce migration of fluid into the adjacent retinal tissue. We sought to determine whether carefully titrated laser photocoagulation combined with vitrectomy and gas tamponade can safely create an effective intraretinal barrier to fluid egress from the optic disc cavitation. DESIGN: Retrospective interventional case series. METHODS: We retrospectively evaluated medical records and imaging studies of 22 consecutive patients with cavitary disc maculopathy evaluated by a single surgeon between 1991 and 2014. Patients requiring surgery underwent carefully titrated juxtapapillary laser photocoagulation followed immediately by vitrectomy and gas tamponade. Main outcome measures were change in visual acuity, macular fluid resolution, and recurrence of maculopathy. RESULTS: Eleven patients (11 eyes) had undergone vitreous surgery and were included in the study. No preoperative evidence for vitreous traction on the optic disc or macula was seen in any eye. Nine patients underwent a single surgery and 2 patients required additional procedures to resolve the macular fluid. Mean length of follow-up after the last surgery was 48.2 months (range, 4-143 months). All 11 patients (100%) had complete resolution of macular fluid, with an average time to resolution of 8.5 months (range, 1-18 months). Only 1 of 11 patients (9%) had recurrence of macular fluid (14 months postoperatively). The average preoperative visual acuity of 20/125 (logMAR 0.81, standard deviation [SD] = 0.36) improved by nearly 4 lines to an average final visual acuity of 20/57 (logMAR 0.45, SD = 0.37) (P = .0072). A possible laser-induced central scotoma was suspected in only 1 patient who had undergone extensive prior laser treatments. CONCLUSIONS: An effective intraretinal barrier to fluid migration from cavitary optic disc anomalies can be safely achieved in most patients with carefully titrated juxtapapillary laser photocoagulation combined with vitrectomy and gas tamponade. Once achieved, the barrier facilitates resolution of macular fluid and long-term avoidance of recurrent maculopathy. PMID- 27697475 TI - Understanding the core of RNA interference: The dynamic aspects of Argonaute mediated processes. AB - At the core of RNA interference, the Argonaute proteins (Ago) load and utilize small guide nucleic acids to silence mRNAs or cleave foreign nucleic acids in a sequence specific manner. In recent years, based on extensive structural studies of Ago and its interaction with the nucleic acids, considerable progress has been made to reveal the dynamic aspects of various Ago-mediated processes. Here we review these novel insights into the guide-strand loading, duplex unwinding, and effects of seed mismatch, with a focus on two representative Agos, the human Ago 2 (hAgo2) and the bacterial Thermus thermophilus Ago (TtAgo). In particular, comprehensive molecular simulation studies revealed that although sharing similar overall structures, the two Agos have vastly different conformational landscapes and guide-strand loading mechanisms because of the distinct rigidity of their L1 PAZ hinge. Given the central role of the PAZ motions in regulating the exposure of the nucleic acid binding channel, these findings exemplify the importance of protein motions in distinguishing the overlapping, yet distinct, mechanisms of Ago-mediated processes in different organisms. PMID- 27697476 TI - Basic units of protein structure, folding, and function. AB - Study of the hierarchy of domain structure with alternative sets of domains and analysis of discontinuous domains, consisting of remote segments of the polypeptide chain, raised a question about the minimal structural unit of the protein domain. The hypothesis on the decisive role of the polypeptide backbone in determining the elementary units of globular proteins have led to the discovery of closed loops. It is reviewed here how closed loops form the loop-n lock structure of proteins, providing the foundation for stability and designability of protein folds/domain and underlying their co-translational folding. Simplified protein sequences are considered here with the aim to explore the basic principles that presumably dominated the folding and stability of proteins in the early stages of structural evolution. Elementary functional loops (EFLs), closed loops with one or few catalytic residues, are, in turn, units of the protein function. They are apparent descendants of the prebiotic ring-like peptides, which gave rise to the first functional folds/domains being fused in the beginning of the evolution of protein structure. It is also shown how evolutionary relations between protein functional superfamilies and folds delineated with the help of EFLs can contribute to establishing the rules for design of desired enzymatic functions. Generalized descriptors of the elementary functions are proposed to be used as basic units in the future computational design. PMID- 27697477 TI - Lysophosphatidylcholines activate PPARdelta and protect human skeletal muscle cells from lipotoxicity. AB - Metabolomics studies of human plasma demonstrate a correlation of lower plasma lysophosphatidylcholines (LPC) concentrations with insulin resistance, obesity, and inflammation. This relationship is not unraveled on a molecular level. Here we investigated the effects of the abundant LPC(16:0) and LPC(18:1) on human skeletal muscle cells differentiated to myotubes. Transcriptome analysis of human myotubes treated with 10MUM LPC for 24h revealed enrichment of up-regulated peroxisome proliferator-activated receptor (PPAR) target transcripts, including ANGPTL4, PDK4, PLIN2, and CPT1A. The increase in both PDK4 and ANGPTL4 RNA expression was abolished in the presence of either PPARdelta antagonist GSK0660 or GSK3787. The induction of PDK4 by LPCs was blocked with siRNA against PPARD. The activation of PPARdelta transcriptional activity by LPC was shown as PPARdelta-dependent luciferase reporter gene expression and enhanced DNA binding of the PPARdelta/RXR dimer. On a functional level, further results show that the LPC-mediated activation of PPARdelta can reduce fatty acid-induced inflammation and ER stress in human skeletal muscle cells. The protective effect of LPC was prevented in the presence of the PPARdelta antagonist GSK0660. Taking together, LPCs can activate PPARdelta, which is consistent with the association of high plasma LPC levels and PPARdelta-dependent anti-diabetic and anti-inflammatory effects. PMID- 27697479 TI - Primary orbital synovial sarcoma: A clinicopathologic review with a differential diagnosis and discussion of molecular genetics. AB - Synovial sarcoma is a soft-tissue sarcoma of the extremities developing in young adults that has rarely been reported in the orbit. Synovial sarcoma is associated with a unique translocation, resulting in an SYT-SSX fusion gene. We analyze 7 published periocular cases, together with the current one, to gain a better appreciation of the features of the tumor in this location and to compare the findings with those derived from nonophthalmic studies. An inferior orbital mass developed in a 31-year-old woman after experiencing periorbital and hemifacial pain for more than a decade. Radiographically, the mass was circumscribed and displayed coarse internal calcifications. A large but subtotal excision with histopathologic examination disclosed a primitive tumor composed of spindled and ovoid cells. Immunohistochemistry demonstrated positivity for nuclear transducin like enhancer of split 1 and membranous CD99, typical for synovial sarcoma. Fluorescence in situ hybridization identified a (X,18) translocation in the tumor cells. The patient underwent postoperative adjuvant proton beam radiotherapy with a good response that has been maintained during 1 year of follow-up. Orbital soft tissue tumors of all types are increasingly identified by their distinctive genetic signatures that offer more specificity than standard immunohistochemical tests. PMID- 27697480 TI - Gene therapy and respiratory neuroplasticity. AB - Breathing is a life-sustaining behavior that in mammals is accomplished by activation of dedicated muscles responsible for inspiratory and expiratory forces acting on the lung and chest wall. Motor control is exerted by specialized pools of motoneurons in the medulla and spinal cord innervated by projections from multiple centers primarily in the brainstem that act in concert to generate both the rhythm and pattern of ventilation. Perturbations that prevent the accomplishment of the full range of motor behaviors by respiratory muscles commonly result in significant morbidity and increased mortality. Recent developments in gene therapy and novel targeting strategies have contributed to deeper understanding of the organization of respiratory motor systems. Gene therapy has received widespread attention and substantial progress has been made in recent years with the advent of improved tools for vector design. Genes can be delivered via a variety of plasmids, synthetic or viral vectors and cell therapies. In recent years, adeno-associated viruses (AAV) have become one of the most commonly used vector systems, primarily because of the extensive characterization conducted to date and the versatility in targeting strategies. Recent studies highlight the power of using AAV to selectively and effectively transduce respiratory motoneurons and muscle fibers with promising therapeutic effects. This brief review summarizes current evidence for the use of gene therapy in respiratory disorders with a primary focus on interventions that address motor control and neuroplasticity, including regeneration, in the respiratory system. PMID- 27697481 TI - Differential induction of dyskinesia and neuroinflammation by pulsatile versus continuous l-DOPA delivery in the 6-OHDA model of Parkinson's disease. AB - Neuroinflammation is associated with l-DOPA treatment in Parkinson's disease (PD), suggesting a role in l-DOPA-induced dyskinesia (LID), however it is unclear whether increased inflammation is specifically related to the dyskinetic outcome of l-DOPA treatment. Diversely from oral l-DOPA, continuous intrajejunal l-DOPA infusion is associated with very low dyskinetic outcome in PD patients. We reproduced these regimens of administration in 6-OHDA-lesioned hemiparkinsonian rats, where dyskinetic responses and striatal neuroinflammation induced by chronic pulsatile (DOPAp) or continuous (DOPAc) l-DOPA were compared. Moreover, we investigated the contribution of a peripheral inflammatory challenge with lipopolysaccharide (LPS), to DOPAp-induced dyskinetic and neuroinflammatory responses. Rats 6-OHDA-infused in the medial forebrain bundle received two weeks treatment with DOPAp, DOPAc via subcutaneous osmotic minipumps, or DOPAp followed by DOPAc. l-DOPA plasma levels were measured in all experimental groups. An independent group of rats received one peripheral dose of LPS 24h before DOPAp treatment. Abnormal involuntary movements (AIMs) were evaluated as a rat model of LID. Immunoreactivity (IR) for OX-42, microglial and neuronal TNF-alpha, iNOS and GFAP was quantified in denervated and contralateral striatum. In addition, serum TNF-alpha was measured. The 6-OHDA denervation induced a mild microgliosis in the striatum two weeks after neurotoxin infusion, and increased TNF-alpha IR in microglia. Rats receiving the DOPAp treatment developed AIMs and displayed increased striatal OX-42, microglial TNF-alpha, iNOS and GFAP. Moreover, TNF alpha IR was also increased in a subpopulation of striatal neurons. Conversely, DOPAc did not induce AIMs or inflammatory responses in either drug-naive animals or rats that were previously dyskinetic when exposed to DOPAp. Serum TNF-alpha was not altered by any l-DOPA treatment. LPS pre-treatment increased the degree of DOPAp-induced AIMs and striatal IR for OX-42, TNF-alpha, iNOS and GFAP. Altogether the present findings indicate that in the 6-OHDA model, chronic l-DOPA induces striatal inflammatory responses, which however depend upon the administration regimen and the dyskinetic outcome of drug treatment. The potentiation of dyskinetic responses by LPS suggests a reciprocal causal link between neuroinflammation and LID.

AB - A total of 420 environmental water samples and 120 drinking water samples from 45 different sampling sites of the Black Sea in Turkey were collected between 2012 and 2014. Genomic DNA was isolated from all the investigated water samples and comparativelly analyzed by Loop-mediated isothermal amplification (LAMP) of the elongation factor 1 Alfa (EF1alpha) gene, and by nested Polymerase Chain Reaction (nPCR) of the small subunit (SSU) rRNA and semi-nested PCR (snPCR) of the glutamate dehydrogenase gene (GDH). 141 (58.7%), 125 (52.1%) and 120 (50%) samples respectivelly were positive by each method. Out of 240 environmental samples collected from 25 sites of Samsun Province have been found positive for G. duodenalis by LAMP, nPCR and snPCR, respectively. 55 (30.5%), 50 (27.8%) and 47 (26.1%) of 180 environmental samples collected from 20 other sampling sites of Giresun Province were positive for Giardia by LAMP, nPCR and snPCR, respectively. Five PCR products from different samples of the Giresun Province and 10 other samples from the Samsun Province were found positive for G. duodenalis assemblage B. Five PCR products from Giresun Province and 5 samples from Samsun Province were found positive for G. duodenalis assemblage A. This is the first report about G. duodenalis assemblages A and B from water samples investigations in Black Sea of Turkey. PMID- 27697478 TI - Sphingolipids in mitochondria. AB - Sphingolipids are bioactive lipids found in cell membranes that exert a critical role in signal transduction. In recent years, it has become apparent that sphingolipids participate in growth, senescence, differentiation and apoptosis. The anabolism and catabolism of sphingolipids occur in discrete subcellular locations and consist of a strictly regulated and interconnected network, with ceramide as the central hub. Altered sphingolipid metabolism is linked to several human diseases. Hence, an advanced knowledge of how and where sphingolipids are metabolized is of paramount importance in order to understand the role of sphingolipids in cellular functions. In this review, we provide an overview of sphingolipid metabolism. We focus on the distinct pathways of ceramide synthesis, highlighting the mitochondrial ceramide generation, transport of ceramide to mitochondria and its role in the regulation of mitochondrial-mediated apoptosis, mitophagy and implications to disease. We will discuss unanswered questions and exciting future directions. This article is part of a Special Issue entitled: Lipids of Mitochondria edited by Guenther Daum.

AB - The increasing globalisation of trades, human movements and environmental changes facilitate the introduction and the establishment of the invasive Asian tiger mosquito Aedes albopictus outside its native geographical area. Alerted by the complaints about mosquito biting which occurred daytime for the inhabitants of the seaside town Ain Turk (West of Algeria), an entomological survey was conducted in December 2015 to determine the origin of this nuisance. Among the collected mosquitoes, specimens of Ae. albopictus (2 males, 3 females and 3 pupae) were collected. This is the first observation of that invasive mosquito in the west of Algeria which confirms its presence and establishment in Mediterranean Africa.

PMID- 27697484 TI - Tobacco use and second-hand smoke exposure in young adolescents aged 12-15 years: data from 68 low-income and middle-income countries. AB - BACKGROUND: Tobacco use is an important risk factor for non-communicable diseases worldwide. However, the global extent and prevalence of tobacco use in adolescents is poorly described. Using previously collected survey data, we aimed to assess tobacco use and second-hand smoke exposure in young adolescents aged 12 15 years in 68 low-income and middle-income countries. METHODS: We used data from the Global School-based Student Health Survey (2006-13) and the China Global Tobacco Youth Survey (2013), which are school-based surveys of young adolescents aged 12-15 years that assess health behaviours using a standardised, anonymous, self-reported questionnaire. We calculated the prevalence of current tobacco use and exposure to second-hand smoke in young adolescents from 68 low-income and middle-income countries that collected these data in the surveys. We used a multilevel model to estimate the association between parental tobacco use, second hand smoke, and adolescent tobacco use, adjusting for sex, age, school, school class, country's purchasing power parity, smoking initiation age, national prevalence of tobacco use among adults, year the WHO FCTC was ratified for each country, proxy of socioeconomic status, and survey year. FINDINGS: The mean prevalence of current tobacco use was 13.6%, ranging from 2.8% in Tajikistan to 44.7% in Samoa. In most countries, the prevalence of tobacco use was higher for boys than girls, and higher for adolescents aged 14-15 years than for those aged 12-13 years. The overall prevalence of second-hand smoke exposure was 55.9%, ranging from 16.4% in Tajikistan to 85.4% in Indonesia. Parental tobacco use (as reported by the young adolescents), especially maternal use, was associated with tobacco use in young adolescents (odds ratio 2.06, 95% CI 1.93-2.19, for maternal and 1.29, 1.23-1.35 for paternal use). Second-hand smoke exposure was also a risk factor for young adolescents' tobacco use (2.56, 2.43-2.69). However, the prevalence of tobacco use was not associated with a country's purchasing power parity. INTERPRETATION: Tobacco use and second-hand smoke exposure were frequent among young adolescents aged 12-15 years in low-income and middle-income countries. Parental tobacco use and second-hand smoke exposure were strongly associated with young adolescents' tobacco use. The data emphasise the need to strengthen tobacco control interventions and programmes in young adolescents from low-income and middle-income countries.

PMID- 27697486 TI - Enhancing speech envelope by integrating hair-cell adaptation into cochlear implant processing. AB - Cochlear implants (CIs) bypass some of the mechanisms that underlie normal neural behavior as occurs in acoustic hearing. One such neural mechanism is short-term adaptation, which has been proposed to have a significant role in speech perception. Acoustically-evoked neural adaptation has been mainly attributed to the depletion of neurotransmitter in the hair-cell to auditory-nerve synapse and is therefore not fully present in CI stimulation. This study evaluated a signal processing method that integrated a physiological model of hair-cell adaptation into CI speech processing. The linear high-pass adaptation process expanded the range of rapid variations of the electrical signal generated by the clinical processing strategy. Speech perception performance with the adaptation-based processing was compared to that of the clinical strategy in seven CI users. While there was large variability across subjects, the new processing improved sentence recognition and consonant identification scores in quiet in all the tested subjects with an average improvement of 8% and 6% respectively. Consonant recognition scores in babble noise were improved at the higher signal-to-noise ratios tested (10 and 6 dB) only. Information transfer analysis of consonant features showed significant improvements for manner and place of articulation features, but not for voicing. Enhancement of within-channel envelope cues was confirmed by consonant recognition results obtained with single-channel strategies that presented the overall amplitude envelope of the signal on a single active electrode. Adaptation-inspired envelope enhancement techniques can potentially improve perception of important speech features by CI users.

AB - Chitosan is insoluble in water due to its rigid crystalline structure, which has significantly restricted its application in wound healing. The objective of this study was to synthesize a water-soluble chitosan derivative, N-succinyl-chitosan (NSC), and evaluate its ability to accelerate the wound healing process. NSC was synthesized with succinic anhydride, hydrochloric acid, and alkaline chitosan under optimized conditions, and characterized using Fourier transform infrared, proton nuclear magnetic resonance, and X-ray diffraction spectroscopy; thermal gravimetric analysis; and a solubility test. The cytotoxicity of NSC was investigated in L929 cells, and its antibacterial activity was evaluated by the inhibition zone method and bacterial growth curves analysis. The results showed that the solubility of NSC was substantially improved compared to chitosan, and NSC was non-toxic with good antibacterial properties. An animal wound healing test indicated that NSC could significantly reduce the healing time compared to chitosan. Histopathological examination suggested that the underlying mechanisms of these effects were related to NSC's ability to promote the formation of granulation tissue and enhance epithelialization. Collectively, these results demonstrate the good potential for NSC to be applied as a wound dressing material. PMID- 27697488 TI - Bioprocess for the production of recombinant HAP phytase of the thermophilic mold Sporotrichum thermophile and its structural and biochemical characteristics. AB - Thermophilc mold Sporotrichum thermophile secretes an acidstable and thermostable phytase, which finds application as a food and feed additive because of its adequate thermostability, acid stability, protease insensitivity and broad substrate spectrum. Low extracellular phytase production by the mold is a major bottleneck for its application on a commercial scale. We have successfully overcome this problem by constitutive secretary expression of codon optimized rStPhy under glyceraldehyde phosphate dehydrogenase (GAP) promoter in Pichia pastoris. A ~41-fold improvement in rStPhy production has been achieved. Circular Dichroism (CD) spectra revealed that rStPhy is composed of 26.65% alpha-helices, 5.26% beta-sheets and 68.09% random coils at pH 5.0 and 60 degrees C, the optima for the enzyme activity. The melting temperature (Tm) of the enzyme is ~73 degrees C. The 3D structure of rStPhy displayed characteristic signature sequences (RHGXRXP and HD) of HAP phytase. The catalytically important amino acids (Arg74, His75, Arg78, His368 and Asp369) were identified by docking and site directed mutagenesis. Fluorescence quenching by N-bromosuccinimide (NBS) and CsCl exposed tryptophan residues surrounded by negative charges, which play a key role in maintaining structural integrity of rStPhy. PMID- 27697489 TI - Fabrication and characterization of bactericidal thiol-chitosan and chitosan iodoacetamide nanofibres. AB - Two chitosan derivatives, namely, thiol-chitosan (TCs) and chitosan iodoacetamide (CsIA) were newly synthesized by reacting Cs with thiglycolic acid (TGA) and iodoacetic acid (IA) respectively. After being crosslinked with glutraldehyde (GA), the two derivatives were submitted to FT-IR and H1 NMR analysis for identification and characterization of their chemical features. As TCs and CsIA are water soluble, their electrospun nanofibres mats from aqueous solutions could be crosslinked and achieved using polyvinyl alcohol/Chitosan blend (PVA/Cs) polymers. Morphological structures of the obtained nanofibres and their webs were studied via those of TCs and CsIA free systems. The data also indicate that the crosslinked PVA/Cs/CsIA is more thermally stable than the crosslinked PVA/Cs/TCs and crosslinked PVA/Cs respectively. It was proved that the electrospun fibers containing TCs or CsIA display a superior antibacterial activity against negative bacteria E. Coli with a minimum inhibitory concentration (MIC) of 400MUg/ml. These effects are rather in confirmation with bacterial kinetics essays which were also carried out in current work. Of particular interest is that the antimicrobial properties of fibers containing small concentration of either TCs or CsIA are much superior than those obtained with neat Cs electrospun nanofibres used as reference. By and large the results advocate the fibers webs containing TCs or CsIA as excellent candidates for wound dressing applications. PMID- 27697490 TI - Chitin hoops obtained from Ommatoiulus sabulosus (Diplopoda, Julidae) used for bovine serum albumin adsorption. AB - A new hoop shaped three dimensional chitin was obtained successfully from the body segment of a diplopod species (Ommatoiulus sabulosus) by following the procedure decolorization, demineralization and deproteinization. Purity of the hoop shaped three-dimensional chitin was proved by FT-IR analysis and chitinase digestive test. The important bands for alpha-chitin such as 1654.2, 1619.7 and 1552cm-1 were found after FT-IR analysis. And the chitinase digestive test revealed the purity of chitin (with digestion rate of 94.7%). SEM analysis showed that the chitin surface consisted of highly porous structure with nanofibers. Thermal stability of the hoop shaped chitin was recorded quite high (DTGmax=383 degrees C). The nitrogen, carbon and hydrogen contents of the hoop shaped chitin were determined as 6.81%, 46.23% and 6.43% respectively. And also degree of acetylation (DA) of the chitin indicated the purity with 95.85%. Chitin hoops-BSA interaction was conducted at different pH, protein concentration and contact time. This new type of three-dimensional chitin obtained from the diplopod body segments can find more effective applications in further studies comparing to the conventional dust forms. PMID- 27697491 TI - Mass cultivation of UV-B adapted Arthrospira platensis RRGK under open raceway pond for the production of Poly-beta-hydroxy butyrate. AB - Six different strains of cyanobacteria were isolated from the freshwater lake, Arakkonam, India. Staining of cells with Nile Red showed the presence of large quantities of PHB granules in the cell cytoplasm of Arthrospira. Molecular identification of the strain was carried out using 16S rRNA analysis and their systematic position was ascertained as Arthrospira platensis RRGK. Studies were carried out on random mutagenesis approach using UV-B radiation for enhancing the production of PHB. Further, Response Surface Methodology was used for optimization of pH, temperature, and sodium bicarbonate for higher biomass and PHB production. Under open raceway pond A. platensis RRGK produced biomass concentration of 2.2+/-0.13gL-1 and 131+/-0.36gL-1 of PHB content. It was chemically characterized through FTIR, DSC, TGA and XRD analyses. Hence, PHB can be produced from cyanobacteria by sequestering harmful CO2. It can also be used as a substitute for synthetic polymers in tissue engineering.

PMID- 27697493 TI - Applications of and Barriers to Holistic Self-Care in a Low-Income, High-Risk Obstetric Population. AB - OBJECTIVE: We examined 1) women's perceptions regarding self-care, 2) applications of self-care, and 3) barriers to practicing effective self-care. METHODS: Four focus groups were conducted in a low-income, pregnant population. Focus group recruitment and discussions took place at a large medical center in a medically underserved area of central Georgia. Thirty-two adult pregnant women attending a high-risk obstetric clinic were included. Data related to holistic self-care were identified and grouped into one of three categories: women's valuations of self-care, applications of self-care, and barriers to self-care. The results were synthesized and compared to results from a study of postpartum women in which the same analytic framework for examining self-care practice was applied. RESULTS: Although women tended to understand the importance of self care, they had difficulty practicing all forms of self-care on a regular basis owing to financial constraints, limited family support, health complications due to their high-risk obstetric status, external commitments, and childcare and household responsibilities. Applications of self-care were typically inexpensive and mainly required time rather than money. CONCLUSIONS: Socioeconomic status seems to influence the specific applications of and barriers to self-care. Health care providers should be aware of existing low-cost resources in the community that may assist prospective and new mothers in tending to their own emotional and physical needs. Providers should also discuss the importance of self-care with women during the perinatal period. Efforts should be made to educate school administrators regarding the impact of spontaneous requests for money for school activities, supplies, and field trips on the family budget. PMID- 27697494 TI - Women Veterans with Depression in Veterans Health Administration Primary Care: An Assessment of Needs and Preferences. AB - OBJECTIVE: Depression is the most prevalent mental health condition in primary care (PC). Yet as the Veterans Health Administration increases resources for PC/mental health integration, including integrated care for women, there is little detailed information about depression care needs, preferences, comorbidity, and access patterns among women veterans with depression followed in PC. METHODS: We sampled patients regularly engaged with Veterans Health Administration PC. We screened 10,929 (10,580 men, 349 women) with the two-item Patient Health Questionnaire. Of the 2,186 patients who screened positive (2,092 men, 94 women), 2,017 men and 93 women completed the full Patient Health Questionnaire-9 depression screening tool. Ultimately, 46 women and 715 men with probable major depression were enrolled and completed a baseline telephone survey. We conducted descriptive statistics to provide information about the depression care experiences of women veterans and to examine potential gender differences at baseline and at seven month follow-up across study variables. RESULTS: Among those patients who agreed to screening, 20% of women (70 of 348) had probable major depression, versus only 12% of men (1,243 of 10,505). Of the women, 48% had concurrent probable posttraumatic stress disorder and 65% reported general anxiety. Women were more likely to receive adequate depression care than men (57% vs. 39%, respectively; p < .05); 46% of women and 39% of men reported depression symptom improvement at the 7-month follow-up. Women veterans were less likely than men to prefer care from a PC physician (p < .01) at baseline and were more likely than men to report mental health specialist care (p < .01) in the 6 months before baseline. CONCLUSION AND IMPLICATIONS FOR PRACTICE: PC/mental health integration planners should consider methods for accommodating women veterans unique care needs and preferences for mental health care delivered by health care professionals other than physicians. PMID- 27697495 TI - Marine pharmacology: therapeutic targeting of matrix metalloproteinases in neuroinflammation. AB - Alterations in matrix metalloproteinase (MMP) expression and activity are recognized as key pathogenetic events in several neurological disorders. This evidence makes MMPs possible therapeutic targets. The search for substances that can inhibit MMPs is moving progressively toward the screening of natural products. In particular, marine bioprospecting could be promising for the discovery of marine natural products with anti-MMP activities. Despite recent advances in this field, the possibility of using marine MMP inhibitors (MMPIs) for the treatment of neuroinflammation is still under-investigated. Here, we review the latest findings in this promising research field and the potential that marine MMPIs can have in the management and treatment of various neurological diseases.

PMID- 27697498 TI - Validation of the Global Allergy and Asthma European Network (GA2LEN) chamber for trials in allergy: Innovation of a mobile allergen exposure chamber. AB - BACKGROUND: Field clinical trials of pollen allergy are affected by the impossibility of predicting and determining individual allergen exposure because of many factors (eg, pollen season, atmospheric variations, pollutants, and lifestyles). Environmental exposure chambers, delivering a fixed amount of allergen in a controlled environmental setting, can overcome these limitations. Environmental exposure chambers are currently already used in phase 2, 3, and even 4 trials. Unfortunately, few chambers exist in the world, and this makes it difficult to perform large, multicenter clinical trials. The new Global Allergy and Asthma European Network (GA2LEN) mobile exposure chamber is a step forward because the mobility of the chamber makes it convenient for patients to participate in clinical testing. OBJECTIVE: This study was made to validate the reproducibility, sensitivity, and specificity of the results obtained in the new GA2LEN chamber. METHODS: Seventy-two adult patients (19-61 years old) with allergic rhinitis with or without asthma caused by grass pollen were included in different clinical validation tests. Total symptom scores and total nasal symptom scores were recorded at time zero (0) and every 10 minutes during exposures, along with nasal and respiratory parameters. RESULTS: Exposure tests confirmed the reproducibility between subsequent runs and the sensitivity (P < .00001 vs patients exposed to placebo) and specificity (very low score in nonallergic subjects) in the GA2LEN chamber. No adverse reactions were recorded during the tests. CONCLUSIONS: The mobility of the GA2LEN chamber provides a new, potentially effective, and safe way of generating reliable data in allergy multicenter clinical trials. PMID- 27697497 TI - Physical health conditions and quality of life in adults with primary immunodeficiency diagnosed during childhood: A French Reference Center for PIDs (CEREDIH) study. AB - BACKGROUND: Most children with primary immunodeficiencies (PIDs) now reach adulthood. However, few studies have evaluated their health status and health related quality of life (HRQoL). OBJECTIVE: To investigate long-term morbidity, the French Reference Center for PIDs initiated a prospective multicenter cohort: the French Childhood Immune Deficiency Long-term Cohort. The data collected were used to assess the physical health condition of patients who reached adulthood and the effect on their quality of life. METHODS: Patients were asked to complete health status questionnaires. A severity score (grade 1 [mild] to grade 4 [life threatening]) was assigned to each health condition. The HRQoL of patients was compared with age- and sex-matched French normal values by using the 36-item Short-Form Survey (SF-36) HRQoL questionnaire. RESULTS: Among 329 participants, the mean age at evaluation was 27.6 years, with a 21-year mean follow-up after diagnosis; 43% reported at least 1 grade 4 health condition, and 86% reported at least 1 grade 3 (severe) or 4 health condition. Twenty-five (7.6%) patients had been treated for cancer. Compared with the French normal values, adults with PIDs scored significantly lower for all HRQoL domains. HRQoL was strongly associated with the burden of health conditions. The association with grade 4 or grade 3-4 health conditions was highly significant for all physical and mental domains. CONCLUSION: Adults with PIDs diagnosed during childhood experienced a heavy burden of health conditions, which affected their HRQoL. Our results emphasize the need to closely monitor this vulnerable population.

PMID- 27697501 TI - Deoxycholic acid derivatives as inhibitors of P-glycoprotein-mediated multidrug efflux. AB - Deoxycholic acid derivatives were designed as P-glycoprotein (Pgp, ABCB1) inhibitors. Thus the synthesis and the biological activity of methyl deoxycholate derivatives 5-10 and their ether analogs 15-20 have been reported. The potency of these compounds to modulate Pgp-mediated MDR was evaluated through daunorubicin accumulation and potentiation of doxorubicin cytotoxicity in K562/R7 multidrug resistant cells overexpressing Pgp. In parallel, their intrinsic toxicity was appreciated on K562 sensitive cells. Methyl 12alpha-[(2R or 2S) tetrahydro-2H pyran-2-yloxy]-3-oxo-5beta-cholan-24-oate 9b has shown a good efficiency as a Pgp inhibitor and a low intrinsic toxicity. Therefore, this derivative constitutes a new lead compound which can be used as a starting point to improve the design of non-toxic Pgp modulators.

AB - Silver sulfadiazine has been frequently used as an antibacterial agent for topical treatment of partial thickness burn wounds. In this study, we present the preparation of silver sulfadiazine microsponges by w/o/w emulsion solvent evaporation method. Formulation variables were optimized by using 32 factorial design. The optimized microsponges were characterized by FTIR, DSC, PXRD, particle size analysis, SEM analysis and mercury intrusion porosimetry studies. Viscosity, texture analysis and ex vivo drug deposition study of optimized microsponge loaded gel were also evaluated. The safety of the optimized gel was assessed by MTT assay using epidermal keratinocyte (HaCaT) and mouse embryonic fibroblast (NIH-3T3) cell lines. In vitro antibacterial studies were carried out to compare the antibacterial inhibitory efficiency of the optimized gel against the commercial product. The efficacy of the optimized gel was evaluated by the partial thickness (second degree) burn wound model in mice. Optimized microsponge loaded gel enhanced the drug retaining capacity in the skin layers, by 3 fold higher to that of a commercial product. The antibacterial inhibitory efficiency of optimized gel was similar to the commercial product against the Staphylococcus aureus and Pseudomonas aeruginosa. Optimized gel showed reduced frequency of application, no skin irritation, low cytotoxicity on dermal cell lines and enhanced wound contraction.

PMID- 27697506 TI - Comparison between semiquantitative and quantitative methods for the assessment of knee synovitis in osteoarthritis using non-enhanced and gadolinium-enhanced MRI. AB - OBJECTIVE: To compare different semiquantitative and quantitative methods using both non-enhanced and gadolinium-enhanced MRI techniques for the assessment of synovitis in knee osteoarthritis (OA). METHODS: Knees with end-stage clinical OA in patients undergoing total knee replacement surgery were included in this cross sectional study. MRI was performed on all knees. Standard non-enhanced and gadolinium-enhanced sequences were acquired. Using non-enhanced MRI, we semiquantitatively assessed two features widely used as surrogates for synovitis: effusion-synovitis and Hoffa-synovitis. Using gadolinium-enhanced sequences, we semiquantitatively assessed synovial thickness. We quantitatively evaluated the total synovial volume on the gadolinium-enhanced sequences as well. We assessed the correlations of effusion-synovitis and Hoffa-synovitis with synovial thickness and volume, applying Spearman correlation analysis. The diagnostic performance of both synovitis features on non-enhanced MRI was assessed using synovial thickness on gadolinium-enhanced MRI as the reference. RESULTS: A total of 104 subjects (one knee per subject) were included. Correlations of effusion synovitis with synovial thickness and volume were r = 0.41 and r = 0.43 (P < .001) r = 0.32 and r = 0.39 (P < .0001). CONCLUSION: Using synovial thickness assessed on gadolinium-enhanced sequences as the reference, effusion-synovitis showed superior correlations and sensitivity. Effusion-synovitis should be preferred over Hoffa-synovitis as a surrogate marker for synovial thickening, in studies of knee OA for which gadolinium-enhanced sequences are not available. PMID- 27697500 TI - Long-term outcomes of 176 patients with X-linked hyper-IgM syndrome treated with or without hematopoietic cell transplantation. AB - BACKGROUND: X-linked hyper-IgM syndrome (XHIGM) is a primary immunodeficiency with high morbidity and mortality compared with those seen in healthy subjects. Hematopoietic cell transplantation (HCT) has been considered a curative therapy, but the procedure has inherent complications and might not be available for all patients. OBJECTIVES: We sought to collect data on the clinical presentation, treatment, and follow-up of a large sample of patients with XHIGM to (1) compare long-term overall survival and general well-being of patients treated with or without HCT along with clinical factors associated with mortality and (2) summarize clinical practice and risk factors in the subgroup of patients treated with HCT. METHODS: Physicians caring for patients with primary immunodeficiency diseases were identified through the Jeffrey Modell Foundation, United States Immunodeficiency Network, Latin American Society for Immunodeficiency, and Primary Immune Deficiency Treatment Consortium. Data were collected with a Research Electronic Data Capture Web application. Survival from time of diagnosis or transplantation was estimated by using the Kaplan-Meier method compared with log-rank tests and modeled by using proportional hazards regression. RESULTS: Twenty-eight clinical sites provided data on 189 patients given a diagnosis of XHIGM between 1964 and 2013; 176 had valid follow-up and vital status information. Sixty-seven (38%) patients received HCT. The average follow-up time was 8.5 +/- 7.2 years (range, 0.1-36.2 years). No difference in overall survival was observed between patients treated with or without HCT (P = .671). However, risk associated with HCT decreased for diagnosis years 1987-1995; the hazard ratio was significantly less than 1 for diagnosis years 1995-1999. Liver disease was a significant predictor of overall survival (hazard ratio, 4.9; 95% confidence limits, 2.2-10.8; P < .001). Among survivors, those treated with HCT had higher median Karnofsky/Lansky scores than those treated without HCT (P < .001). Among patients receiving HCT, 27 (40%) had graft-versus-host disease, and most deaths occurred within 1 year of transplantation. CONCLUSION: No difference in survival was observed between patients treated with or without HCT across all diagnosis years (1964-2013). However, survivors treated with HCT experienced somewhat greater well-being, and hazards associated with HCT decreased, reaching levels of significantly less risk in the late 1990s. Among patients treated with HCT, treatment at an early age is associated with improved survival. Optimism remains guarded as additional evidence accumulates. PMID- 27697507 TI - Chemokine receptor CXCR2 in dorsal root ganglion contributes to the maintenance of inflammatory pain. AB - Chemokines and their receptors have been demonstrated to be important contributors to the development and maintenance of chronic pain. Recent studies showed that chemokine (C-X-C motif) ligand 1 (CXCL1) and its major receptor CXCR2 are respectively expressed in astrocytes and neurons in the spinal cord and are involved in the maintenance of neuropathic pain and inflammatory pain via astrocytic-neuronal interaction. Here we investigated how CXCL1 and CXCR2 are regulated in the dorsal root ganglion (DRG) after peripheral injection of complete Freund's adjuvant (CFA) and its implication in inflammatory pain. CFA induced rapid increase of CXCL1 mRNA and protein in the DRG. Double immunostaining showed that CXCL1 was colocalized with calcitonin gene-related peptide (CGRP), isolectin B4 (IB4), and neurofilament 200 (NF200). Furthermore, CXCR2 mRNA was increased 3h after CFA injection and maintained for more than 3 days. CXCR2 protein was also increased and colocalized with CGRP, IB4, and NF200. Finally, perisciatic nerve injection of CXCR2 siRNA to specifically knock down CXCR2 in the DRG effectively attenuated CFA-induced mechanical allodynia and heat hyperalgesia, and the effect maintained for more than 5 days.

PMID- 27697511 TI - Liposomal systems as viable drug delivery technology for skin cancer sites with an outlook on lipid-based delivery vehicles and diagnostic imaging inputs for skin conditions'. AB - Skin cancer is among one of the most common human malignancies wide-spread world over with mortality statistics rising continuously at an alarming rate. The increasing frequency of these malignancies has marked the need for adopting effective treatment plan coupled with better and site-specific delivery options for the desired therapeutic agent's availability at the affected site. The concurrent delivery approaches to cancerous tissues are under constant challenge and, as a result, are evolving and gaining advancements in terms of delivery modes, therapeutic agents and site-specificity of the therapeutics delivery. The lipid-based liposomal drug delivery is an attractive and emerging option, and which is meticulously shaping up beyond a threshold level to a promising, and viable route for the effective delivery of therapeutic agents and other required injuctions to the skin cancer. An update on liposomal delivery of chemotherapeutic agents, natural-origin compounds, photosensitizer, and DNA repair enzymes as well as other desirable and typical delivery modes employed in drug delivery and in the treatment of skin cancers is discussed in details. Moreover, liposomal delivery of nucleic acid-based therapeutics, i.e., small interfering RNA (siRNA), mRNA therapy, and RGD-linked liposomes are among the other promising novel technology under constant development. The current clinical applicability, viable clinical plans, future prospects including transport feasibility of delivery vesicles and imaging techniques in conjunction with the therapeutic agents is also discussed. The ongoing innovations in liposomal drug delivery technology for skin cancers hold promise for further development of the methodology for better, more effective and site-specific delivery as part of the better treatment plan by ensuring faster drug transport, better and full payload delivery with enough and required concentration of the dose. PMID- 27697512 TI - DHCR7: A vital enzyme switch between cholesterol and vitamin D production. AB - The conversion of 7-dehydrocholesterol to cholesterol, the final step of cholesterol synthesis in the Kandutsch-Russell pathway, is catalyzed by the enzyme 7-dehydrocholesterol reductase (DHCR7). Homozygous or compound heterozygous mutations in DHCR7 lead to the developmental disease Smith-Lemli Opitz syndrome, which can also result in fetal mortality, highlighting the importance of this enzyme in human development and survival. Besides serving as a substrate for DHCR7, 7-dehydrocholesterol is also a precursor of vitamin D via the action of ultraviolet light on the skin. Thus, DHCR7 exerts complex biological effects, involved in both cholesterol and vitamin D production. Indeed, we argue that DHCR7 can act as a switch between cholesterol and vitamin D synthesis. This review summarizes current knowledge about the critical enzyme DHCR7, highlighting recent findings regarding its structure, transcriptional and post-transcriptional regulation, and its links to vitamin D synthesis. Greater understanding about DHCR7 function, regulation and its place within cellular metabolism will provide important insights into its biological roles.

AB - The use of nanocarriers to enhance drug delivery efficacy has been increasing in the healthcare field due to their tunable surface properties. In this study, ceftriaxone-loaded solid lipid nanoparticles (CL-SLNPs) were synthesized using a water-in-oil-in-water (w/o/w) type double emulsification method. The formulation was optimized using response surface methodology (RSM) and was characterized using transmission electron microscopy (TEM), photon correlation spectroscopy (PCS), and UV-vis and Fourier transform infrared (FTIR) spectroscopy. The CL SLNPs were of spherical shape, 15-20nm in size, and retained the properties of the drug or other constituents/ingredients after loading. The prepared nanoformulation offered sustained drug release after 24h, while ceftriaxone sodium followed a burst release. Antibacterial activity of the nanoformulation was evaluated against different gram-positive and gram-negative bacterial strains. The minimum inhibitory concentration of CL-SLNPs against Pseudomonas aeruginosa was determined as 31MUg/mL. PMID- 27697514 TI - Time-varying associations of suicide with deployments, mental health conditions, and stressful life events among current and former US military personnel: a retrospective multivariate analysis. AB - BACKGROUND: US military suicides have increased substantially over the past decade and currently account for almost 20% of all military deaths. We investigated the associations of a comprehensive set of time-varying risk factors with suicides among current and former military service members. METHODS: We did a retrospective multivariate analysis of all US military personnel between 2001 and 2011 (n=110 035 573 person-quarter-years, representing 3 795 823 service members). Outcome was death by suicide, either during service or post-separation. We used Cox proportional hazard models at the person-quarter level to examine associations of deployment, mental disorders, history of unlawful activity, stressful life events, and other demographic and service factors with death by suicide. FINDINGS: The strongest predictors of death by suicide were current and past diagnoses of self-inflicted injuries, major depression, bipolar disorder, substance use disorder, and other mental health conditions (compared with service members with no history of diagnoses, the hazard ratio [HR] ranged from 1.4 [95% CI 1.14-1.72] to 8.34 [6.71-10.37]). Compared with service members who were never deployed, hazard rates of suicide (which represent the probability of death by suicide in a specific quarter given that the individual was alive in the previous quarter) were lower among the currently deployed (HR 0.50, 95% CI 0.40-0.61) but significantly higher in the quarters following first deployment (HR 1.51 [1.17 1.96] if deployed in the previous three quarters; 1.14 [1.06-1.23] if deployed four or more quarters ago). The hazard rate of suicide increased within the first year of separation from the military (HR 2.49, 95% CI 2.12-2.91), and remained high for those who had separated from the military 6 or more years ago (HR 1.63, 1.45-1.82). INTERPRETATION: The increased hazard rate of death by suicide for military personnel varies by time since exposure to deployment, mental health diagnoses, and other stressful life events. Continued monitoring is especially needed for these high-risk individuals. Additional information should be gathered to address the persistently raised risk of suicide among service members after separation. FUNDING: Partly funded by the Naval Research Program. PMID- 27697516 TI - Outer membrane protein 100 of Aggregatibacter actinomycetemcomitans act as a biopharmaceutical target for photodynamic therapy: An in silico analysis. AB - BACKGROUND: Periodontitis is a polymicrobial, chronic, and degenerative disease that can lead to destruction of the teeth-supporting tissues and eventually to loss of teeth. Aggregatibacter actinomycetemcomitans is predominantly associated with periodontal diseases. Outer membrane protein (Omp) 100 is a more important virulence factor of A. actinomycetemcomitans due to the effect of adhesion and invasion into human gingival epithelial cells. Attachment of A. actinomycetemcomitans inhibition is significant in the treatment process. METHODS: We evaluated the capacity of Omp100 in A. actinomycetemcomitans as a novel target for photodynamic therapy (PDT) using a range of bioinformatic tools. In silico analysis was used to predict molecular modeling, the hierarchical nature of protein structure and backbone, and sub-cellular localization. RESULTS: The results showed that Omp100 is most similar to thiamine-phosphate pyrophosphorylase [Haemophilus influenzae PittGG], with a 74% similarity. The predicted structure of Omp100 displayed that it is a protein with positive charge (10.4) in pH 7 and alpha helix dominates other secondary structures located outside the cell. Protein-protein interaction network showed that Omp100 interacted with extracellular matrix protein adhesion, glycoside hydrolase, Omp 64, phospholipase D/Transphosphatidylase, Flp pilus assembly protein, and heme acquisition system receptor. CONCLUSION: According to the results, anionic indocyanine green tends to interact with Omp100 during PDT as a major target. PMID- 27697517 TI - Neuroprotective effects of cyanidin against Abeta-induced oxidative and ER stress in SK-N-SH cells. AB - This study evaluated the mechanisms underlying the protective effect of cyanidin against Abeta25-35-induced neuronal cell death in SK-N-SH cells. Abeta25-35 induced neurotoxicity is characterized by a decrease in cell viability, inducing the expression of endoplasmic reticulum (ER) stress proteins; an increase in intracellular reactive oxygen species (ROS) production; and an increase in intracellular calcium release. Abeta25-35 also induces neuronal toxicity through the disturbance of ER calcium levels. Pretreatment with cyanidin significantly attenuated the Abeta25-35-induced loss of cell viability, reducing the expression of endoplasmic reticulum (ER) stress response proteins with regard to the down regulation of the expression levels of 78 kDa glucose regulated protein (Grp78), phosphorylated forms of pancreatic ER elF2alpha kinase (PERK), eukaryotic initiation factor 2 alpha (eIF2alpha), and inositol-requiring enzyme 1 (IRE1), and the expression levels of X-box binding protein 1 (XBP-1), activating transcription factor 6 (ATF6), and CCAAT/enhancer binding protein homologous transcription factor (C/EBP) homologous protein (CHOP); decreased intracellular ROS production; decreased intracellular calcium release; and reduced down regulation of the protein expression levels of calpain and cleaved caspase-12. This result suggests that cyanidin may be an alternative agent in preventing neurodegenerative diseases. PMID- 27697518 TI - Metabolic flexibility of mitochondrial respiratory chain disorders predicted by computer modelling. AB - Mitochondrial respiratory chain dysfunction causes a variety of life-threatening diseases affecting about 1 in 4300 adults. These diseases are genetically heterogeneous, but have the same outcome; reduced activity of mitochondrial respiratory chain complexes causing decreased ATP production and potentially toxic accumulation of metabolites. Severity and tissue specificity of these effects varies between patients by unknown mechanisms and treatment options are limited. So far most research has focused on the complexes themselves, and the impact on overall cellular metabolism is largely unclear. To illustrate how computer modelling can be used to better understand the potential impact of these disorders and inspire new research directions and treatments, we simulated them using a computer model of human cardiomyocyte mitochondrial metabolism containing over 300 characterised reactions and transport steps with experimental parameters taken from the literature. Overall, simulations were consistent with patient symptoms, supporting their biological and medical significance. These simulations predicted: complex I deficiencies could be compensated using multiple pathways; complex II deficiencies had less metabolic flexibility due to impacting both the TCA cycle and the respiratory chain; and complex III and IV deficiencies caused greatest decreases in ATP production with metabolic consequences that parallel hypoxia. Our study demonstrates how results from computer models can be compared to a clinical phenotype and used as a tool for hypothesis generation for subsequent experimental testing. These simulations can enhance understanding of dysfunctional mitochondrial metabolism and suggest new avenues for research into treatment of mitochondrial disease and other areas of mitochondrial dysfunction. PMID- 27697519 TI - Mechanical perspectives on the anterior-posterior axis polarization of mouse implanted embryos. AB - In most mammals, embryonic development and growth proceed in the maternal uterus. Mouse late blastocyst embryos implant on the uterine epithelium around embryonic day (E)4.5, and immediately afterward the whole embryo's shape is dynamically changed from a bowl-like shape to an elongated egg-cylinder until E5.5. Concurrently, mouse anterior-posterior (A-P) axis polarization occurs by the emergence of distal visceral endoderm (DVE) cells at the cellular and molecular levels as the proximal-distal (P-D) axis. The embryonic growth and axis polarization are considered to be controlled primarily by multiple growth factors' signaling. However, the precise cellular mechanisms of DVE formation in which this signaling is involved have been unclear. We recently identified that local breaching of the basement membrane (BM) between the epiblast and the visceral endoderm (VE) at the distal tip allows inner epiblast cells to transmigrate into the outer VE layer as the emergence of DVE cells. More importantly, the local BM loss in the distal region appears to be triggered by mechanical forces exerted from maternal tissues on embryos and embryonic growth itself. Our data suggest a fascinating hypothesis concerning mouse A-P axis polarization mediated by the whole embryo's shape change through mechanical stress between the embryo and the uterine epithelium. Our mechanical model provides a unique insight into why the first axis polarity of the implanted mouse embryo is established in the P-D direction initially and not in the future A-P direction. We also discuss whether the local breaching of the BM mediated by mechanical cues is essential to mouse A-P axis polarization in in vitro culture. PMID- 27697520 TI - Forces driving cell sorting in the amphibian embryo. AB - Adhesion differences are the main driver of cell sorting and related processes such as boundary formation or tissue positioning. In the early amphibian embryo, graded variations in cadherin density and localized expression of adhesion modulating factors are associated with regional differences in adhesive properties including overall adhesion strength. The role of these differences in embryonic boundary formation has not been studied extensively, but available evidence suggests that adhesion strength differentials are not essential. On the other hand, the inside-out positioning of the germ layers is correlated with adhesion strength, although the biological significance of this effect is unclear. By contrast, the positioning of dorsal mesoderm tissues along the anterior-posterior body axis is essential for axis elongation, but the underlying sorting mechanism is not correlated with adhesion strength, and may rely on specific cell adhesion. Formation of the ectoderm-mesoderm boundary is the best understood sorting related process in the frog embryo. It relies on contact induced cell repulsion at the tissue interface, driven by Eph-ephrin signaling and paraxial protocadherin-dependent self/non-self recognition. PMID- 27697521 TI - Activation of arginine vasopressin receptor 1a facilitates the induction of long term potentiation in the accessory olfactory bulb of male mice. AB - Olfaction plays an important role in social recognition in most mammals. Central arginine vasopressin (AVP) plays a role in this olfaction-based recognition. The high level of expression of AVP receptors in the accessory olfactory bulb (AOB) at the first relay of the vomeronasal system highlights the importance of AVP signaling at this stage. We therefore analyzed the effects of AVP on the synaptic plasticity of glutamatergic transmission from mitral cells to granule cells in AOB slices from male mice. To monitor the strength of the glutamatergic transmission, we measured the maximal initial slope of the lateral olfactory tract-evoked field potential, which represents the granule cell response to mitral cell activation. AVP paired with 100-Hz stimulation that only produced short-term potentiation enhanced the induction of long-term potentiation (LTP) in a dose-dependent manner. AVP-paired LTP was blocked by the selective AVP receptor 1a (AVPR1a) antagonist, d(CH2)5[Tyr(Me)2]AVP (Manning compound), but not by the AVPR1b antagonist SSR149415, and it was mimicked by the selective AVPR1a agonist [Phe2, Ile3, Orn8]-vasopressin. We further examined the effect of AVP on the reciprocal transmission between mitral and granule cells by stimulating a mitral cell and recording the evoked inhibitory postsynaptic currents (IPSCs) from the same cell using conventional whole-cell patch-clamp techniques. AVP reduced the reciprocal IPSCs triggered by endogenous glutamate release from the excited mitral cell. These results suggest that AVP promotes the induction of LTP at the mitral-to-granule cell synapse via the activation of AVPR1a through an as-yet-to be-determined mechanism in the AOB of male mice. PMID- 27697522 TI - Golgi protein 73 facilitates the interaction of hepatitis C virus NS5A with apolipoprotein E to promote viral particle secretion. AB - Hepatitis C virus (HCV) infection is one of the leading causes of chronic liver diseases and hepatocellular carcinoma (HCC). Golgi protein 73 (GP73), a resident Golgi membrane protein, is a novel serum biomarker for the diagnosis of liver diseases and HCC. Although previous studies have demonstrated that HCV upregulates GP73 expression and GP73 promotes HCV secretion through its interaction with apolipoprotein E (ApoE), the exact mechanism underlying GP73 regulates HCV secretion remains unclear. In this study, we demonstrated that GP73 mediates the interaction of ApoE with HCV NS5A protein to promote HCV secretion. We revealed that GP73 is colocalized with HCV replication complex in infected Huh7.5.1 cells. Further studies demonstrated that GP73 interacted with both NS5A and ApoE proteins. Furthermore, knockdown of GP73 significantly reduced the binding of NS5A with ApoE, and the production of virus particles in culture supernatant. Taken together, our studies revealed that GP73 promotes HCV secretion by directly mediating the interaction of ApoE with HCV replication complex through binding with HCV NS5A. PMID- 27697523 TI - TGF-beta-induced phosphorylation of Akt and Foxo transcription factors negatively regulates induced regulatory T cell differentiation. AB - Transforming growth factor-beta (TGF-beta) is a pivotal cytokine in the differentiation of regulatory T cells, and Foxo transcription factors positively regulate this process. On the other hand, the function of Foxo transcription factors is negatively regulated by PI3K/Akt signaling, which is activated by TGF beta in many types of cells; yet the role of TGF-beta in Akt activity and its downstream substrates in CD4+ T cells, including Foxo transcription factors, remains to be determined. Herein, we demonstrate that TGF-beta selectively induces Akt phosphorylation at Ser473 but not at Thr308 in a class IA PI3K dependent manner in CD4+ T cells, resulting in the phosphorylation and inhibition of Foxo transcription factors and negatively regulating the differentiation of induced regulatory T cells (iTregs). These observations reveal a novel negative regulatory mechanism involving Akt and Foxo transcription factors induced by TGF beta in the iTreg differentiation process. PMID- 27697524 TI - Mouse Apolipoprotein L9 is a phosphatidylethanolamine-binding protein. AB - Mouse Apolipoprotein L9 (ApoL9) is an understudied cytoplasmic, interferon inducible protein. The details of its intracellular localization and normal cellular functions are unclear. We report here that ApoL9 localizes to small puncta diffusely distributed in the cytoplasm, as well as to larger granules of varying size and number that are similar to aggresome-like induced structures (ALIS) and contain the autophagy receptor Sqstm1/p62, the autophagosome marker Lc3, and ubiquitin. Transfection of B16F10 mouse melanoma cells stably expressing ApoL9 (B16F10L9) with certain liposome-based transfection reagents causes dramatic disturbances in its subcellular distribution. We reasoned that these disturbances may be due to the interaction of ApoL9 with dioleoylphosphatidylethanolamine (DOPE), the helper lipid component of several transfection reagents. Recombinant ApoL9 produced in E. coli, as well as ApoL9 expressed in HEK293T cells, specifically bind phosphatidylethanolamine (PE) in vitro. ApoL9 is expressed at high levels in liver and brain, organs enriched in PE. Since PE is known to facilitate replication of positive strand RNA viruses, we examined the role of ApoL9 during replication of Japanese encephalitis virus (JEV), a positive strand virus of the family Flaviviridae. JEV titres in B16F10L9 cells are higher than those in B16F10 cells. We propose that ApoL9 is a PE binding protein that may have important roles in several cellular processes that involve this phospholipid. PMID- 27697525 TI - Long-term fructose consumption prolongs hepatic stearoyl-CoA desaturase 1 activity independent of upstream regulation in rats. AB - Dietary fructose is considered a risk factor for metabolic disorders, such as fatty liver disease. However, the mechanism underlying the effects of fructose is not well characterized. We investigated the hepatic expression of key regulatory genes related to lipid metabolism following fructose feeding under well-defined conditions. Rats were fed standard chow supplemented with 10% w/v fructose solution for 5 weeks, and killed after chow-fasting and fructose withdrawal (fasting) or chow-fasting and continued fructose (fructose alone) for 14 h. Hepatic deposition of triglycerides was found in rats from both groups. As expected, fructose alone increased mRNA levels of lipogenesis-related genes and correspondingly decreased mRNA levels of lipid oxidative genes in the liver. Interesting, hepatic levels of stearoyl-CoA desaturase (SCD)1 mRNA remained elevated under fructose withdrawn conditions, although expression levels of other genes, including two key transcription factors (carbohydrate response element binding protein (ChREBP) and sterol regulatory element-binding protein (SREBP) 1c) fell to normal levels, indicating that long-term fructose intake increased SCD1 activity, independent of upstream regulatory genes, such as ChREBP and SREBP 1c. In conclusion, SCD1 overexpression in fatty liver disease is not affected by fasting after long-term fructose consumption in rats. Regulation of SCD1 plays an important role in fructose-induced hepatic steatosis. PMID- 27697526 TI - BCKA down-regulates mTORC2-Akt signal and enhances apoptosis susceptibility in cardiomyocytes. AB - Diabetic mellitus (DM) portends poor prognosis concerning pressure overloaded heart disease. Branched-chain amino acids (BCAAs), elements of essential amino acids, have been found altered in its catabolism in diabetes decades ago. However, the relationship between BCAAs and DM induced deterioration of pressure overloaded heart disease remains controversial. This study is aimed to investigate the particular effect of BCKA, a metabolite of BCAA, on myocardial injury induced by pressure overloaded. Primary cardiomyocytes were incubated with or without BCKA and followed by treatment with isoproterenol (ISO); then cell viability was detected by CCK8 and apoptosis was examined by TUNNEL stain and caspase-3 activity analysis. Compared to non-BCKA incubated group, BCKA incubation decreased cell survival and increased apoptosis concentration dependently. Furthermore, Western blot assay showed that mTORC2-Akt pathway was significantly inactivated by BCKA incubation. Moreover, overexpression of rictor, a vital component of mTORC2, significantly abolished the adverse effects of BCKA on apoptosis susceptibility of cardiomyocytes. These results indicate that BCKA contribute to vulnerability of cardiomyocytes in stimulated stress via inactivation of mTORC2-Akt pathway. PMID- 27697527 TI - Discovery of germacrene A synthases in Barnadesia spinosa: The first committed step in sesquiterpene lactone biosynthesis in the basal member of the Asteraceae. AB - The Andes-endemic Barnadesioideae lineage is the oldest surviving and phylogenetically basal subfamily of the Asteraceae (Compositae), a prolific group of flowering plants with world-wide distribution (~24,000 species) marked by a rich diversity of sesquiterpene lactones (STLs). Intriguingly, there is no evidence that members of the Barnadesioideae produce STLs, specialized metabolites thought to have contributed to the adaptive success of the Asteraceae family outside South America. The biosynthesis of STLs requires the intimate expression and functional integration of germacrene A synthase (GAS) and germacrene A oxidase (GAO) to sequentially cyclize and oxidize farnesyl diphosphate into the advanced intermediate germacrene A acid leading to diverse STLs. Our previous discovery of GAO activity conserved across all major subfamilies of Asteraceae, including the phylogenetically basal lineage of Barnadesioideae, prompted further investigation of the presence of the gateway GAS in Barnadesioideae. Herein we isolated two terpene synthases (BsGAS1/BsGAS2) from the basal Barnadesia spinosa (Barnadesioideae) that displayed robust GAS activity when reconstituted in yeast and characterized in vitro. Despite the apparent lack of STLs in the Barnadesioideae, this work unambiguously confirms the presence of GAS in the basal genera of the Asteraceae. Phylogenetic analysis reveals that the two BsGASs fall into two distinct clades of the Asteraceae's GASs, and BsGAS1 clade is only retained in the evolutionary closer Cichorioideae subfamily, implicating BsGAS2 is likely the ancestral base of most GASs found in the lineages outside the Barnadesioideae. Taken together, these results show the enzymatic capacities of GAS and GAO emerged prior to the subsequent radiation of STL-producing Asteraceae subfamilies. PMID- 27697528 TI - Doxorubicin-induced epithelial-mesenchymal transition through SEMA 4A in hepatocellular carcinoma. AB - Semaphorins are essential for the functions in the regulation of cell migration. SEMA 4A has been proven to play a prominent role in immune function and angiogenesis. However, whether SEMA 4A is involved in HCC chemoresistance is unclear. We investigated the role of SEMA 4A in HCC chemoresistance and the underlying mechanisms. We tested the doxorubicin sensitivity of the Huh7, and Hep G2 HCC cell lines. Immunofluorescence and Western blot were used to detect the location and expression of EMT-related protein, such as, E-cadherin, Vimentin, and SEMA4A expression. Microarray data showed that SEMA 4A and SEMA 3F increased most dramatically under DOX treatment. Kncokdown of SEMA 4A in hepatoma cells can reduce EMT process. Expectedly, depletion of SEMA 4A also reversed EMT and increased the DOX sensitivity. SEMA 4A confers doxorubicin resistance on HCC by inducing epithelial-mesenchymal transition (EMT). PMID- 27697529 TI - Cox-2 promotes mesenchymal stem cells differentiation into cardiocytes by activating JNK and ERK pathway. AB - Coronary heart disease and various cardiomyopathys may cause myocardial damage, reducing the number of myocardial cells with complete functions. Cyclooxygenase 2 (Cox-2) has been reported participating in a variety of pathological processes, including tumor invasion and metastasis. In this study, we sought to explore the correlation of Cox-2 with MSCs proliferation, and migration. MSCs were transfected with pcDNA-Cox2 and NS-398 to promote or inhibit the expression of Cox2. Then, MTT, transwell, qRT-PCR and western blot were used to test the influence of Cox2 on cells proliferation, cells migration and cell viability of mesenchymal stem. The results show that Cox-2 promotes directional differentiation of myocardial cells and the overexpression of cox-2 can activate the key factors of JNK and ERK signaling pathway, promotes myocardial cell directional differentiation. PMID- 27697530 TI - Identification and characterization of NPC1L1 variants in Uygur and Kazakh with extreme low-density lipoprotein cholesterol. AB - BACKGROUND: Plasma levels of low-density lipoprotein cholesterol (LDL-C) are a major risk factor for cardiovascular disease and are influenced by both heredity and dietary habits. The Niemann-Pick C1 like 1 (NPC1L1) protein mediates efficient dietary cholesterol absorption and contributes to variations in human LDL-C levels. METHODS: In the present study, using high throughput sequencing we identified three non-synonymous (NS) variations and 64 synonymous variations in the NPC1L1 gene from subsets of Chinese Han, Uygur and Kazakh populations with high or low LDL-C. Subsequently, three NS variations encoding R174H, V177I and V1284L substitutions were observed only in Uygur and Kazakh individuals with limited maximal plasma LDL-C levels. RESULTS: In further experiments, we investigated cholesterol-regulated recycling and glycosylation and stability of these NS NPC1L1 variants. However, no significant differences between WT and variant NPC1L1 proteins were observed using in vivo assays in mouse livers with adenovirus-mediated expression, demonstrating that none of the three NPC1L1 NS variants caused decreased uptake of biliary cholesterol. CONCLUSIONS: Simultaneously, these data indicate that R174H, V177I and V1284L NPC1L1 variations in high or low LDL-C individuals may not directly influence cholesterol absorption by NPC1L1. PMID- 27697531 TI - PMEPA1, a TGF-beta- and hypoxia-inducible gene that participates in hypoxic gene expression networks in solid tumors. AB - Prostate transmembrane protein, androgen induced 1 (PMEPA1) is highly expressed in various solid tumors and is known to play important roles in the transforming growth factor-beta (TGF-beta) signaling pathway. Here, we demonstrate a novel relationship between PMEPA1 and hypoxia, a common microenvironmental stress condition in solid tumors. We showed that induction of PMEPA1 expression occurred during hypoxia in a manner dependent on both TGF-beta signaling and hypoxia inducible factor-1 (HIF-1) pathways. Furthermore, overexpression and knockdown experiments revealed that PMEPA1 enhanced HIF-1 transcription activity. Bioinformatics analyses of PMEPA1-correlated genes using a gene expression database in clinical settings showed significant enrichment of gene sets defined by TGF-beta and hypoxia and these two signaling pathways-related angiogenesis and epithelial-mesenchymal transition in many types of solid tumors. Collectively, our findings indicated that PMEPA1 participates in TGF-beta- and hypoxia regulated gene expression networks in solid tumors and thereby may contribute to tumor progression. PMID- 27697532 TI - PEP-1-SIRT2-induced matrix metalloproteinase-1 and -13 modulates type II collagen expression via ERK signaling in rabbit articular chondrocytes. AB - Matrix metalloproteinases (MMPs) are critical for the degradation of the extracellular matrix (ECM), which includes cartilage-specific collagen types I, II and XI. We previously found that PEP-1-sirtuin (SIRT)2 could induce dedifferentiation of articular chondrocytes; however, the underlying mechanisms remains unclear. We addressed this in the present study by examining the association between PEP-1-SIRT2 and the expression of MMP-1 and MMP-13 and type II collagen in rabbit articular chondrocytes. We found that PEP-1-SIRT2 increased MMP-1 and -13 expression in a dose- and time-dependent manner, as determined by western blotting. A similar trend in MMP-1 and -13 levels was observed in cultures during expansion to four passages. Pharmacological inhibition of MMP-1 and -13 blocked the PEP-1-SIRT2-induced decrease in type II collagen level. Phosphorylation of extracellular regulated kinase (ERK) was increased by PEP-1 SIRT2; however, treatment with the mitogen-activated protein kinase inhibitor PD98059 suppressed PEP-1-SIRT2-induced MMP-1 and -13 expression and dedifferentiation while restoring type II collagen expression in passage 2 cells. These results suggest that PEP-1-SIRT2 promotes MMP-induced dedifferentiation via ERK signaling in articular chondrocytes. PMID- 27697533 TI - Exercise and Hypertension: Uncovering the Mechanisms of Vascular Control. AB - Hypertension (HTN) has recently been determined to be the number one overall risk factor of disease. With direct and indirect costs amounting to $46.4 billion in 2011 and projections of six-fold increases by 2030, the importance of low-cost nonpharmacological interventions can be appreciated. Vascular structural changes, endothelial dysfunction, and sympathetic overstimulation are major contributing factors to the pathophysiology of HTN. Exercise training (ET) for blood pressure (BP) control has been shown to be an effective and integral component of nonpharmacological interventions for BP control. Different ET modalities (aerobic, resistance, and concurrent training) have contributed differently to BP reduction and control, driving scientific discourse regarding the optimum ET prescription (modality, volume, and intensity) for such effects; ET results in a multitude of physiological effects, with vascular and autonomic adaptations providing major contributions to BP control. Despite widespread acceptance of the role and importance of ET for BP reduction, only 15% of US adults have been found to meet ET/physical activity recommendations. The purpose of this review is to explore BP lowering effects of aerobic and resistance ET and the underlying physiological mechanisms that result in such effects. Further research is required to enhance our understanding of the proper ET prescription for BP control across different age groups and racial ethnicities. Furthermore, research into methods of improving awareness and adherence to ET recommendations proves to be equally important. PMID- 27697534 TI - Emerging roles of the neurotrophin receptor TrkC in synapse organization. AB - Tropomyosin-receptor-kinase (Trk) receptors have been extensively studied for their roles in kinase-dependent signaling cascades in nervous system development. Synapse organization is coordinated by trans-synaptic interactions of various cell adhesion proteins, a representative example of which is the neurexin neuroligin complex. Recently, a novel role for TrkC as a synapse organizing protein has been established. Post-synaptic TrkC binds to pre-synaptic type-IIa receptor-type protein tyrosine phosphatase sigma (PTPsigma). TrkC-PTPsigma specifically induces excitatory synapses in a kinase domain-independent manner. TrkC has distinct extracellular domains for PTPsigma- and NT-3-binding and thus may bind both ligands simultaneously. Indeed, NT-3 enhances the TrkC-PTPsigma interaction, thus facilitating synapse induction at the pre-synaptic side and increasing pre-synaptic vesicle recycling in a kinase-independent fashion. A crystal structure study has revealed the detailed structure of the TrkC-PTPsigma complex as well as competitive modulation of TrkC-mediated synaptogenesis by heparan sulfate proteoglycans (HSPGs), which bind the same domain of TrkC as PTPsigma. Thus, there is strong evidence supporting a role for the TrkC-PTPsigma complex in mechanisms underlying the fine turning of neural connectivity. Furthermore, disruption of the TrkC-PTPsigma complex may be the underlying cause of certain psychiatric disorders caused by mutations in the gene encoding TrkC (NTRK3), supporting its role in cognitive functions.

AB - AIMS: To determine an association between hs-CRP and metabolic control/diabetic chronic vascular complications (DCVCCxs) in the patients with type 2 diabetes (DM). In addition, the possibility of using hs-CRP levels to predict risk of DCVCCxs will also be validated. METHODS: This cohort study randomly enrolled 608 patients with DM during the 2007-2008 study period. We also recorded basic laboratory findings at baseline and at one year, to include fasting plasma glucose, HbA1c, triglyceride, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and hs-CRP. RESULTS: Logistic regressions of odds ratios between hs-CRP and DCVCCxs (coronary arterial disease, cerebrovascular disease, diabetic nephropathy, diabetic retinopathy, and diabetic peripheral neuropathy) showed significant correlations, except for cerebrovascular disease, as follows 0.2 (0.11-0.38), 0.09 (0.01-0.77), 0.06 (0.02 0.16), 0.31 (0.12-0.82), and 0.17 (0.07-0.43), respectively. Linear regression for changes in hs-CRP were significantly correlated with HbA1c (r=0.38), fasting plasma glucose (r=0.40), triglyceride (r=0.20), low-density lipoprotein cholesterol (r=0.12), and high-density lipoprotein cholesterol (r=-0.12). No correlation was found for total cholesterol (r=0.06). Based on receiver operating characteristic (ROC) analysis, the cut-off points for hs-CRP levels for prediction of DCVCCxs were 2.89, 2.25, 2.10, 2.25, and 2.82mg/L, for coronary arterial disease, cerebrovascular disease, diabetic nephropathy, diabetic retinopathy, and diabetic peripheral neuropathy, respectively. CONCLUSIONS: Our data showed that DCVCCxs were associated with hs-CRP in patients with DM. The cut off point for hs-CRP can be used to predict association with DCVCCxs. Well controlled metabolic components in diabetic patients, especially HbA1c, fasting plasma glucose, and triglyceride may reduce the level of hs-CRP. PMID- 27697535 TI - Levels of physical activity are correlated with intima media ratio in subjects without but not with metabolic syndrome: A study of Iranians without a history of cardiovascular events. AB - AIM: We aimed to investigate the relationship between carotid Intima Media Thickness (CIMT) and physical activity levels (PAL), in subjects with and without metabolic syndrome (MetS) and in indidiviuals with and without carotid artery plaque (CAP) defined using high-resolution ultrasound. METHOD: A sample of 506 subjects [215 (42.5%) males], aged 35-64 years was recruited from an urban population in Mashhad, Iran, using a stratified-cluster method as part of the Mashhad Stroke Heart Atherosclerosis Disorder (MASHAD) study cohort. This sub sample was selected randomly from a cohort of 9765 individuals for carotid duplex ultrasound. Comparisons were made between individuals with and without CAP on the one hand, and between participants with and without MetS on the other hand with regard to physical activity and cardiometabolic risk level, as well as their correlation with CIMT. RESULT: PAL was positively and significantly correlated with CIMT in the total sample (r=0.132, p<0.001). The correlation coefficient was 0.132 (p=0.426) in the MetS+ participants and 0.440 (p<0.001) in the MetS- participants. The correlation of PAL with CIMT was also positive and significant in CAP+ participants (r=0.150, p<0.001), but not in the CAP- participants (r= 0.001, p=0.621), with however a non-significant difference between the two estimates (p=0.374). Hip circumference was correlated with CIMT in MetS- but not MetS+ participants. CONCLUSION: physical activity in the current study appeared to be a correlate of infraclinical CVD risk in participants without metabolic syndrome, but not in those without. PMID- 27697537 TI - Macrophages are essential for maintaining a M2 protective response early after ischemic brain injury. AB - Resident microglia and recruited macrophages are major contributors to the post ischemic inflammatory response. Initially considered functionally homogeneous populations, data now suggest distinct but still controversial roles after brain injury. Using a model of conditional monocyte/macrophage depletion we studied the contribution of these myeloid cells to brain lesion progression after ischemia, and their influence on the ischemic inflammatory environment. Male CD11b-DTR transgenic mice, expressing the human diphtheria toxin receptor under the control of the CD11b promoter, were treated with diphtheria toxin to induce monocyte/macrophage depletion. Twenty four hours later the middle cerebral artery was permanently occluded. The ischemic lesion was measured 24h after injury. At the same time microglia and macrophage activation and polarization were assessed by quantitative immunohistochemistry and confocal microscopy for CD45high, CD11b, CD68, CD16/32, iNOS, Arg1, Ym1, and CD206, and gene expression was investigated on CD11b+ sorted cells. Depletion of monocytes/macrophages worsened the ischemic lesion within 24h after the ischemic insult. This effect was associated with higher M1/M2 polarization ratio in the ischemic lesion. Moreover, depletion increased the expression of M1 phenotypic markers on CD11b positive cells. Gene expression on CD11b+ sorted cells indicated a selective increase of iNOS and lower Arg1 mRNA expression than in non depleted mice. Depletion of monocytes/macrophages increases the ischemic lesion, an effect accompanied by an increase in the M1/M2 polarization ratio of microglia and macrophages in the ischemic area. Thus in ischemic injury recruited monocytes/macrophages may control an excessive M1 pro-inflammatory response, suggesting their ability to drive M2 protective polarization. PMID- 27697538 TI - Relationships of comorbidities and old age with postoperative complications of head and neck free flaps: A review. AB - The aim of this study was to determine the relationships between free flap complications and old age or comorbidities. In a PubMed and Scopus search, the search terms (1) free flap OR microvascular anastomosis AND (2) elderly OR old age AND (3) complications OR comorbidity OR co-morbidity were used. Among the 62 full-text articles from 241 abstracts, 31 papers without sufficient content were excluded and 10 mined papers were added. Subsequently, 41 papers were reviewed. Overall complication rates of free flap increased significantly with age (p < 0.001; y = 0.457x + 13.464; 40.9% at 60 years, 45.5% at 70 years, and 50.0% at 80 years). Flap survival rates increased significantly (p < 0.001; y = 0.025x + 93.876). Donor site complication rates also increased significantly with age (p < 0.001; y = 1.238x - 63.700; 10.9% at 60 years, 23.0% at 70 years, and 35.3% at 80 years). The Kaplan-Feinstein index (KFI, OR = 7.944, 9.563), the Adult Comorbidity Evaluation-27 (ACE-27, OR = 5.854), the American Society of Anesthesiologists score (ASA, OR = 4.397), and the Index of Coexistent Diseases score (ICED, OR = 3.584) had statistically significant impacts on flap survival (p < 0.05). Diabetes (OR = 4.562) and chronic obstructive pulmonary disease (OR = 2.300) had statistically significant negative impacts on the flap survival rate (p < 0.05). Elderly patients had significantly higher Charlson Comorbidity Index (CCI) and ASA scores (p < 0.001). Similarly, elderly patients exhibited a significantly higher prevalence of dementia (p < 0.001) and use of aspirin at the time of surgery (p < 0.001). On the basis of these results, we suggest that the incidence of complications is directly related to the preoperative medical condition of an individual patient rather than to age. PMID- 27697539 TI - Development of a decellularization method to produce nerve allografts using less invasive detergents and hyper/hypotonic solutions. AB - BACKGROUND: Here, we describe a novel method of processing decellularized nerve grafts using osmotic effects of hypotonic and hypertonic solutions and Triton X 100 (a nonionic detergent) and CHAPS (an amphoteric detergent). MATERIALS AND METHODS: To evaluate decellularization, the devised method and Hudson's method were compared with respect to remaining cellular components (as assessed by H&E staining and S-100 immunoreactivity) and extracellular matrix structural integrity (as assessed by H&E staining and laminin immunoreactivity) by using rat sciatic nerves. In addition, a 1.5-cm sciatic nerve gap rat model was treated by implanting decellularized nerve grafts prepared using the devised method, Hudson's method, or an autograft to evaluate nerve regeneration. Nerve histomorphometry of distal stumps and wet muscle mass were evaluated at 12 weeks after implantation. RESULTS: The devised method produced outcomes similar to those of Hudson's method in terms of cellular component removal, but the devised method was significantly better in terms of ECM preservation. Histomorphometric study showed that the devised method produced significantly fewer nerve fiber and axonal densities than autografting, but much more than Hudson's method. The wet muscle mass of the devised method was also significantly lower than that of autografting, but much higher than that of Hudson's method. CONCLUSION: The described process for producing decellularized nerve grafts yielded better outcomes with respect to peripheral nerve regeneration than the established ionic detergent-based methods in a rat model. This study indicates that decellularized nerve grafts produced in this manner show favorable nerve regeneration used for bridging nerve gaps. PMID- 27697540 TI - Harmful effects behind the daily supplementation of a fixed vegetarian blend in the rat model. AB - Fruit and vegetables (FV) have long been considered a panacea against major chronic diseases, including cancer. However, there is no convincing epidemiological, clinical or experimental evidence supporting FV chemopreventive ability. A daily mono-supplementation of lyophilized onion, tomato, peach, black grape or lettuce was compared with the daily combined administration of the same FV (5 a day-like diet). Ten days post-treatment, the phase-I/II xenobiotic metabolizing and antioxidant enzyme activities, protein and mRNA levels were investigated. As a marker of oxidative stress, the level of hydroperoxides was measured in rat serum samples. Here we show that a blend of FV orally administered to rats not only potentially manipulates metabolism but also disrupts systemic oxidative homeostasis. A daily combination of the five servings remarkably down-regulates the catalytic activity, protein and mRNA levels of a cohort of hepatic metabolizing enzymes, suggesting a possible depressed clearance upon exposure to ubiquitous carcinogens. Strikingly, we observed an impairment of antioxidant enzymes with a boost in systemic hydroperoxide levels. Our study identifies new potential factors of cancer risk connected with the persistent consumption of fixed servings of FV, suggesting that dietary guidance should rely on a "daily diversification" of FV.

AB - : The use of this material under current conditions is supported by existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data show that this material is not genotoxic nor does it have skin sensitization potential. The local respiratory toxicity endpoint was completed using the TTC (Threshold of Toxicological Concern) for a Cramer Class I material (1.4 mg/day). The repeated dose toxicity endpoint was completed using ethylene dodecanedioate (CAS # 54982-83-1) as a suitable read across analog, which provided a MOE > 100. The developmental and reproductive toxicity endpoint was completed using oxacyclohexadec-12-en-2-one, (12E)- (CAS # 111879-80-2) as a suitable read across analog, which provided a MOE > 100. The phototoxicity/photoallergenicity endpoint was completed based on suitable UV spectra along with data on the target material. The environmental endpoint was completed as described in the RIFM Framework along with data on the suitable read across analog oxacyclohexadec-12-en-2-one, (12E)- (CAS # 111879-80-2). PMID- 27697544 TI - Gadolinium deposition: Is it chelated or dissociated gadolinium? How can we tell? AB - The methodology and published work aimed at speciation of gadolinium based contrast agents in tissues is reviewed. The discussion focusses on the context of Gd deposited long term in tissue following administration of the contrast agents. Detection of Gd without identification of the chemical form detected is simple and straight forward using a variety of methods. Determination of the chemical form of Gd detected is far more complex and most methods require inherently imperfect extraction steps that can alter the Gd chemical species detected. Control studies wherein Gd is not deposited biologically or is deposited in animal tissues are also inherently imperfect. Strengths and weaknesses of the various methods used and examples are demonstrated. It is concluded that a combination of spatially resolved mass spectral based methods, combined with extraction/HPLC analysis methods can provide sufficient sensitivity, spatial resolution and chemical species specificity to address the title question on ex vivo tissue samples.

PMID- 27697543 TI - Hemorheological characteristics of red blood cells exposed to surface functionalized graphene quantum dots. AB - Graphene quantum dots (GQDs) are potential candidates for various biomedical applications such as drug delivery, bioimaging, cell labeling, and biosensors. However, toxicological information on their effects on red blood cells (RBCs) and the mechanisms involved remain unexplored. To the best of our knowledge, our study is the first to investigate the toxicity effects of three GQDs with different surface functionalizations on the hemorheological characteristics of human RBCs, including hemolysis, deformability, aggregation, and morphological changes. RBCs were exposed to three different forms of GQDs (non-functionalized, hydroxylated, and carboxylated GQDs) at various concentrations (0, 500, 750, and 1000 MUg/mL) and incubation times (0, 1, 2, 3, or 4 h). The rheological characteristics of the RBCs were measured using microfluidic-laser diffractometry and aggregometry. Overall, the hemolysis rate and rheological alterations of the RBCs were insignificant at a concentration less than 500 MUg/mL. Carboxylated GQDs were observed to have more substantial hemolytic activity and caused abrupt changes in the deformability and aggregation of the RBCs than the non functionalized or hydroxylated GQDs at concentrations >750 MUg/mL. Our findings indicate that hemorheological assessments could be utilized to estimate the degree of toxicity to cells and to obtain useful information on safety sheets for nanomaterials. PMID- 27697545 TI - Antivirals against animal viruses. AB - Antivirals are compounds used since the 1960s that can interfere with viral development. Some of these antivirals can be isolated from a variety of sources, such as animals, plants, bacteria or fungi, while others must be obtained by chemical synthesis, either designed or random. Antivirals display a variety of mechanisms of action, and while some of them enhance the animal immune system, others block a specific enzyme or a particular step in the viral replication cycle. As viruses are mandatory intracellular parasites that use the host's cellular machinery to survive and multiply, it is essential that antivirals do not harm the host. In addition, viruses are continually developing new antiviral resistant strains, due to their high mutation rate, which makes it mandatory to continually search for, or develop, new antiviral compounds. This review describes natural and synthetic antivirals in chronological order, with an emphasis on natural compounds, even when their mechanisms of action are not completely understood, that could serve as the basis for future development of novel and/or complementary antiviral treatments. PMID- 27697547 TI - Neuromuscular contributions to the age-related reduction in muscle power: Mechanisms and potential role of high velocity power training. AB - Although much of the literature on neuromuscular changes with aging has focused on loss of muscle mass and isometric strength, deficits in muscle power are more pronounced with aging and may be a more sensitive measure of neuromuscular degeneration. This review aims to identify the adaptations to the neuromuscular system with aging, with specific emphasis on changes that result in decreased muscle power. We discuss how these changes in neuromuscular performance can affect mobility, and ultimately contribute to an increased risk for falls in older adults. Finally, we evaluate the literature regarding high-velocity muscle power training (PT), and its potential advantages over conventional strength training for improving functional performance and mitigating fall risk in older adults. PMID- 27697546 TI - Dysfunction of the neurovascular unit in ischemic stroke and neurodegenerative diseases: An aging effect. AB - Current understanding on the mechanisms of brain injury and neurodegeneration highlights an appreciation of multicellular interactions within the neurovascular unit (NVU), which include the evolution of blood-brain barrier (BBB) damage, neuronal cell death or degeneration, glial reaction, and immune cell infiltration. Aging is an important factor that influences the integrity of the NVU. The age-related physiological or pathological changes in the cellular components of the NVU have been shown to increase the vulnerability of the NVU to ischemia/reperfusion injury or neurodegeneration, and to result in deteriorated brain damage. This review describes the impacts of aging on each NVU component and discusses the mechanisms by which aging increases NVU sensitivity to stroke and neurodegenerative diseases. Prophylactic or therapeutic perspectives that may delay or diminish aging and thus prevent the incidence of these neurological disorders will also be reviewed. PMID- 27697549 TI - A human cellular system for analyzing signaling during corneal endothelial barrier dysfunction. AB - Correct corneal endothelial barrier function is essential for maintaining corneal transparency. However, research on cell signaling pathways mediating corneal endothelial barrier dysfunction has progressed more slowly than that involving other cellular barriers because of the lack of human corneal endothelial cell models. Here we have optimized the culture of the human corneal endothelial cell (HCEC) line B4G12 as a model for studying paracellular permeability. We show that B4G12-HCECs form confluent monolayers with stable cell-cell junctions when cultured on plastic, but not glass, surfaces precoated with various extracellular matrix components. Cell morphometry and measuring intercellular spaces and transendothelial electric resistance indicate that B4G12-HCECs form optimal monolayers on collagen and fibronectin. Based on the use of specific inhibitors, it has been proposed that the Rho-regulated kinases, ROCK-I and ROCK-II, mediate actomyosin-induced contraction in corneal endothelial cell barriers. ROCKs are effectors of RhoA, RhoB and RhoC. We show that the GTPase RhoA and its effector ROCK-II are predominantly expressed in B4G12-HCECs and primary human corneal endothelial cells. The activation of Rho GTPases during acute barrier disruption has not been investigated in corneal endothelial cells. RhoA, but not other related GTPases that are highly expressed in B4G12-HCECs, such as Rac1 and Cdc42, is transiently activated during barrier disruption in response to the inflammatory mediator thrombin. Pharmacological inhibition of RhoA and ROCK reduces B4G12-HCEC acute contraction. We propose that exploiting B4G12-HCECs is a useful experimental strategy for gaining further insight into the signaling pathways involved in human corneal endothelial barrier function. PMID- 27697548 TI - Alteration in cellular turnover and progenitor cell population in lacrimal glands from thrombospondin 1-/- mice, a model of dry eye. AB - The purpose of this study was to investigate the changes that occur in the lacrimal glands (LGs) in female thrombospondin 1 knockout (TSP1-/-) mice, a mouse model of the autoimmune disease Sjogren's syndrome. The LGs of 4, 12, and 24 week old female TSP1-/- and C57BL/6J (wild type, WT) mice were used. qPCR was performed to measure cytokine expression. To study the architecture, LG sections were stained with hematoxylin and eosin. Cell proliferation was measured using bromo-deoxyuridine and immunohistochemistry. Amount of CD47 and stem cell markers was analyzed by western blot analysis and location by immunofluorescence microscopy. Expression of stem cell transcription factors was performed using Mouse Stem Cell Transcription Factors RT2 Profiler PCR Array. Cytokine levels significantly increased in LGs of 24 week-old TSP1-/- mice while morphological changes were detected at 12 weeks. Proliferation was decreased in 12 week-old TSP1-/- mice. Three transcription factors were overexpressed and eleven underexpressed in TSP1-/- compared to WT LGs. The amount of CD47, Musashi1, and Sox2 was decreased while the amount of ABCG2 was increased in 12 week-old TSP1-/- mice. We conclude that TSP1 is necessary for maintaining normal LG homeostasis. Absence of TSP1 alters cytokine levels and stem cell transcription factors, LG cellular architecture, decreases cell proliferation, and alters amount of stem cell markers. PMID- 27697550 TI - The cold driver: Cold stress while driving results in dangerous behavior. AB - Cool vehicle cabin temperatures can induce short-term non-hypothermic cold stress. The current study created a cold condition to examine the impact of cold stress on driving behavior. Forty-four participants drove a high-fidelity driving simulator during a thermal neutral or local torso cooled condition. Participants performed additional tasks to assess attention, psychomotor vigilance, and manual dexterity. Skin temperature was significantly lower in the cold condition while internal temperature was unaffected. Participants who had higher subjective ratings of cold followed lead vehicles closer and started to brake later. Participants in the cold condition followed the lead car 22% (0.82s) closer and started braking 20% (2.35s) later when approaching a stop sign during the car following task. No change in attention, psychomotor vigilance, or dexterity was observed. The current results suggest that cold environmental conditions can contribute to dangerous driving behaviors. Measures of cold perception were also shown to predict changes in driving behavior. PMID- 27697551 TI - Frontal EEG theta/beta ratio as an electrophysiological marker for attentional control and its test-retest reliability. AB - A robust finding is that resting-state frontal theta/beta ratio (TBR), a spontaneous electroencephalographic (EEG) frequency band parameter, is increased in attention-deficit/hyperactivity disorder. Accumulating evidence suggests that TBR might also provide an objective marker of executive cognitive control (and more specifically attentional control; AC) in healthy adults. The present study aimed to further investigate this conception by assessing EEG frequency band power and AC twice (with a one-week interval) in 41 young female adults. In line with our predictions, the negative association between TBR and trait AC, as measured with an often used self-report measure, was replicated. Results also demonstrated that test-retest reliability of resting-state frontal TBR was very good (r=.93) and, moreover, TBR measured at the first session predicted AC during the second session (r=-.44). These consistent results further reinforce the notion that frontal TBR could be used as a reliable biomarker for prefrontally mediated executive AC. PMID- 27697552 TI - Driving performance and EEG fluctuations during on-the-road driving following sleep deprivation. AB - The present study mainly aimed to assess whether and how sleepiness due to sleep deprivation interacts with Time on Task (ToT) effects both on electroencephalography (EEG) measures and driving performance in real driving conditions. Healthy participants performed a one hour on-the-road monotonous highway driving task while EEG was recorded continuously after one night of normal sleep and after one night of total sleep deprivation. The main outcome parameter in the highway driving test was the Standard Deviation of Lateral Position (SDLP). SDLP and EEG indices (i.e alpha and theta power spectra) increased after sleep deprivation and varied with ToT. The latter was more pronounced after sleep deprivation. Beta power spectra did not differ between conditions but increased with ToT. Changes in SDLP and EEG did not correlate significantly. We conclude that driving performance as well as fatigue and sleepiness fluctuations with ToT were more evident after sleep deprivation as compared to normal sleep. PMID- 27697553 TI - Acute buspirone dosing enhances abuse-related subjective effects of oral methamphetamine. AB - There is not an approved pharmacotherapy for treating methamphetamine use disorder. This study sought to determine the effects of acute buspirone treatment on the subjective and cardiovascular effects of oral methamphetamine in order to provide an initial assessment of the utility, safety, and tolerability of buspirone for managing methamphetamine use disorder. We predicted that acute buspirone administration would reduce the subjective effects of methamphetamine. We also predicted that the combination of buspirone and methamphetamine would be safe and well tolerated. Ten subjects completed the protocol, which tested three methamphetamine doses (0, 15, and 30mg) in combination with two buspirone doses (0 and 30mg) across 6 experimental sessions. Subjective effects and physiological measures were collected at regular intervals prior to and after dose administration. Methamphetamine produced prototypical subjective and cardiovascular effects. Acute buspirone administration increased some of the abuse-related subjective effects of methamphetamine and also attenuated some cardiovascular effects. The combination of oral methamphetamine and buspirone was safe and well tolerated. Acute buspirone administration may increase the abuse liability of oral methamphetamine. Chronic buspirone dosing studies remain to be conducted, but given preclinical findings and the outcomes of this work, the utility of buspirone for treating methamphetamine use disorder appears limited. PMID- 27697555 TI - Transition from ethanol-induced sensitization to tolerance across early and late infancy in the rat. AB - Drugs of abuse, as cocaine or amphetamine, induce locomotor sensitization during infancy and adulthood of the rat. This effect during the preweanling period is observed only after a short interval of time between training and testing. We recently reported short-term locomotor sensitization induced by ethanol in pups chronically exposed to the drug during the second postnatal week of life. The present series of experiments was designed to explore the persistence of the sensitization effect across the preweanling period. Pups were chronically exposed to ethanol in five consecutive days during the second or the third postnatal weeks, and their locomotor activity was evaluated in an open field 3, 8 or 15days later. Our results showed that, contrarily to what has been observed with other drugs during infancy, sensitization to ethanol persisted at least 8days in rats exposed to the drug during the second postnatal week. Surprisingly, in older pups, the same procedure induced tolerance instead sensitization. This ontogenetic model offers a potentially interesting tool for studying within the same species, how tolerance and sensitization are interrelated, and how these effects affect ethanol-mediated reinforcement and ethanol intake during ontogeny. PMID- 27697556 TI - Multiple colonisations of the Lake Malawi catchment by the genus Opsaridium (Teleostei: Cyprinidae). AB - It has been proposed that the fish faunas of African rivers assemble through multiple colonisation events, while lake faunas form additionally through intralacustine speciation. While this pattern has been established for many lineages, most notably cichlids, there are opportunities to further investigate the concept using phylogenies of congeneric endemic species within ancient lake catchments. The Lake Malawi catchment contains three river-spawning cyprinids of the genus Opsaridium, two of which are endemic. These species differ in body size, migratory behaviour and habitat use, but it has never previously been tested if these represent a monophyletic radiation, or have instead colonised the lake independently. We placed these species in a broader phylogeny of Opsaridium and the related genus Raiamas, including all known species from the river systems surrounding Lake Malawi. Our results suggest that each of the species has independently colonised the lake catchment, with all three taxa having well defined sister taxa outside of the lake, and all sharing a common ancestor ~14.9million years ago, before the Lake Malawi basin started to form ~8.6million years ago. Additionally, the results strongly support previous observations that Opsaridium is not a monophyletic group, but instead contains Raiamas from the Congo drainage. Together these results are supportive of the concept that river fish faunas within African catchments are primarily assembled through a process of accumulation from independent origins, rather than within-catchment speciation and adaptive radiation. In light of these results we also suggest there is scope for a re-evaluation of systematics of both Opsaridium and Raiamas. PMID- 27697554 TI - Efficacy of an adenovirus-based anti-cocaine vaccine to reduce cocaine self administration and reacqusition using a choice procedure in rhesus macaques. AB - Immunopharmacotherapy offers an approach for treating cocaine abuse by specifically targeting the cocaine molecule and preventing its access to the CNS. dAd5GNE is a novel cocaine vaccine that attenuates the stimulant and the reinforcing effects of cocaine in rats. The goal of this study was to extend and validate dAd5GNE vaccine efficacy in non-human primates. Six experimentally naive adult female rhesus monkeys (Macaca mulatta) were trained to self-administer 0.1mg/kg/injection intravenous (i.v.) cocaine or receive candy; then 4 monkeys were administered the vaccine and 2 monkeys were administered vehicle intramuscularly, with additional vaccine boosts throughout the study. The reinforcing effects of cocaine were measured during self-administration, extinction, and reacquisition (relapse) phases. Serum antibody titers in the vaccinated monkeys remained high throughout the study. There was no change in the preference for cocaine over candy over a 20-week period in 5 of the 6 monkeys; only one of the 4 (25%) vaccinated monkeys showed a decrease in cocaine choice. All 6 monkeys extinguished responding for cocaine during saline extinction testing; vaccinated monkeys tended to take longer to extinguish responding than control monkeys (17.5 vs. 7.0 sessions). Vaccination substantially retarded reacquisition of cocaine self-administration; control monkeys resumed cocaine self-administration within 6-41 sessions and 1 vaccinated monkey resumed cocaine self-administration in 19 sessions. The other 3 vaccinated monkeys required between 57 and 94 sessions to resume cocaine self-administration even in the context of employing several manipulations to encourage cocaine reacquisition. These data suggest that the dAdGNE vaccine may have therapeutic potential for humans who achieve cocaine abstinence as part of a relapse prevention strategy. PMID- 27697557 TI - DNA shuffling approach for recombinant polyvalent OmpAs against V. alginolyticus and E. tarda infections. AB - Molecular breeding via DNA shuffling directs the evolution of vaccines with desired traits. In the present study, polyvalent OmpA vaccines were generated by DNA shuffling of five ompA genes from four species of bacteria Vibrio parahaemolyticus, V. alginolyticus, Edwardsiella tarda and Escherichia coli. First, a new hybrid OmpA was constructed using VA0764 primers and used for construction of a prokaryotic expressing library PompAs-FV containing 84 ompAs, which were validated by PCR and SDS/PAGE. Then, the 84 ompAs were used to construct a eukaryotic expressing library EompAs-FV for preparing DNA vaccines. Third, extracellular bacterium V. alginolyticus challenge post active immunization using these DNA vaccines was carried out to identify genes with high immunoprotection. Among the 84 ompAs, 17 showed higher or equal immune protection against infection caused by V. alginolyticus than control VA0764. Finally, immune protection against infection caused by intracellular bacterium Edwardsiella tarda was assessed further using the top seven out of the 17 ompAs. This led to identification of three efficient polyvalent vaccines against infections caused by the extracellular bacterium V. alginolyticus and intracellular bacterium E. tarda. In addition, we sequenced genes for understanding mechanisms of the polyvalent vaccines, but association of immune protection with mutation of gene and amino acids is not determined. These results indicate that DNA shuffling is an efficient way to develop polyvalent vaccines against microbial infections. PMID- 27697558 TI - Changes in the levels of humoral immune activities after storage of gilthead seabream (Sparus aurata) skin mucus. AB - Skin mucus is increasingly used as a source for determining immunity-related proteins and enzymes. However, the ability to accurately measure some activities may be modified by inadequate handling and storage of the samples. This study aims to measure the effect of freezing and lyophilization at the time of collection on such activities. Fresh, frozen (immediately after collection at -20 degrees C and -80 degrees C) and lyophilized skin mucus samples obtained from the same groups of fish specimens of gilthead seabream (Sparus aurata L.) were analysed in the assays. The amount of total proteins and sugar residues (determined by lectin binding) present in skin mucus samples fell after both freezing and lyophilization of the samples. While no significant differences were exhibited in the levels of some proteins or enzymes (immunoglobulin M, antiprotease, peroxidase, esterase and alkaline phosphatase) determined in fresh or frozen mucus samples, protease and lysozyme activities were lower in frozen mucus samples than in fresh samples. Lyophilization of the mucus samples drastically decreased the total level of proteins obtained, as well as of protease, peroxidase, lysozyme and alkaline phosphatase activities. The results suggest that freezing skin mucus samples is more suitable than lyophilization if samples are stored before determining enzymatic activities. PMID- 27697559 TI - Polymorphism in a serine protease inhibitor gene and its association with the resistance of bay scallop (Argopecten irradians) to Listonella anguillarum challenge. AB - Serine protease inhibitors (SPIs) play a crucial role in regulation of both host and bacterial serine protease. They are classified into several protein families, where Kazal-type inhibitors are one of families with multi-domain. In the present study, the polymorphism of AiSPI from Bay scallop Argopecten irradians was found to be associated with disease resistance of bay scallop against Listonella anguillarum. Nine single nucleotide polymorphisms (SNPs) were identified in the exon region of AiSPI, where five SNPs were non-synonymous mutation. Three of these mutations were located in "kazal-like 3"domain, two SNP loci positioned at +536, +1312 were selected for further association studies. For the locus +536, the genotype frequency of A/G in the resistant stock (12.8%) was significantly lower (p < 0.05) than that in the susceptible stock (35.1%), while, the genotype A/A in the resistant stock (87.2%) was significantly higher in comparison with susceptible stock (64.9%) (p < 0.05). The G allele frequencies were 6.4% and 17.6% in resistant stock and susceptible stock, respectively, and chi2-test revealed a significant difference in the frequency distribution between the two stocks (p < 0.05). But there was no significant association between the mutation C-T at locus +1312 with either resistant or susceptible group (p > 0.05). The genotype frequencies of T/T, T/C, C/C at locus +1312 were 94.6%, 2.7% and 2.7% respectively in the susceptible stock, while 100%, 0% and 0% respectively in the resistant stock. The amino acid change for the mutation at locus +536 A-G was from asparagine to serine, and the predicted homology model of this amino acid variation could affect its function as well as the structural integrity of the domain. In vitro elastase inhibition assay of the protein variants at locus +536 was conducted to explicate the effect of SNP. The increasing concentration of protein (0 mmol/L- 2.93 mmol/L) was incubated with 80 nmol/L elastase where the residual enzyme activity values for rAiSPI (N) with A variant and rAiSPI (S) with G variant were started to reduce from 0.40 to 0.215 and 0.435 to 0.356, respectively. The elastase inhibition ability of rAiSPI (N) variant was significantly higher than that of rAiSPI (S) (p < 0.01). The results suggested that the mutation at locus +536A/A significantly associated with disease resistance of bay scallop would shed light for selective breeding program. PMID- 27697560 TI - Genomic structure and expression pattern of MHC IIalpha and IIbeta genes reveal an unusual immune trait in lined seahorse Hippocampus erectus. AB - The major histocompatibility complex (MHC) genes are crucial in the adaptive immune system, and the gene duplication of MHC in animals can generally result in immune flexibility. In this study, we found that the lined seahorse (Hippocampus erectus) has only one gene copy number (GCN) of MHC IIalpha and IIbeta, which is different from that in other teleosts. Together with the lack of spleen and gut associated lymphatic tissue (GALT), the seahorse may be referred to as having a partial but natural "immunodeficiency". Highly variable amino acid residues were found in the IIalpha and IIbeta domains, especially in the alpha1 and beta1 domains with 9.62% and 8.43% allelic variation, respectively. Site models revealed seven and ten positively selected positions in the alpha1 and beta1 domains, respectively. Real-time PCR experiments showed high expression levels of the MHC II genes in intestine (In), gill (Gi) and trunk kidney (TK) and medium in muscle (Mu) and brood pouch (BP), and the expression levels were significantly up regulated after bacterial infection. Specially, relative higher expression level of both MHC IIalpha and IIbeta was found in Mu and BP when compared with other fish species, in which MHC II is expressed negligibly in Mu. These results indicate that apart from TK, Gi and In, MU and BP play an important role in the immune response against pathogens in the seahorse. In conclusion, high allelic variation and strong positive selection in PBR and relative higher expression in MU and BP are speculated to partly compensate for the immunodeficiency. PMID- 27697561 TI - Structural Insight into Recognition of Methylated Histone H3K4 by Set3. AB - The plant homeodomain (PHD) finger of Set3 binds methylated lysine 4 of histone H3 in vitro and in vivo; however, precise selectivity of this domain has not been fully characterized. Here, we explore the determinants of methyllysine recognition by the PHD fingers of Set3 and its orthologs. We use X-ray crystallographic and spectroscopic approaches to show that the Set3 PHD finger binds di- and trimethylated states of H3K4 with comparable affinities and employs similar molecular mechanisms to form complexes with either mark. Composition of the methyllysine-binding pocket plays an essential role in determining the selectivity of the PHD fingers. The finding that the histone-binding activity is not conserved in the PHD finger of Set4 suggests different functions for the Set3 and Set4 paralogs. PMID- 27697562 TI - Engineering nonphosphorylative metabolism to synthesize mesaconate from lignocellulosic sugars in Escherichia coli. AB - Dicarboxylic acids are attractive biosynthetic targets due to their broad applications and their challenging manufacturing process from fossil fuel feedstock. Mesaconate is a branched, unsaturated dicarboxylic acid that can be used as a co-monomer to produce hydrogels and fire-retardant materials. In this study, we engineered nonphosphorylative metabolism to produce mesaconate from d xylose and l-arabinose. This nonphosphorylative metabolism is orthogonal to the intrinsic pentose metabolism in Escherichia coli and has fewer enzymatic steps and a higher theoretical yield to TCA cycle intermediates than the pentose phosphate pathway. Here mesaconate production was enabled from the d-xylose pathway and the l-arabinose pathway. To enhance the transportation of d-xylose and l-arabinose, pentose transporters were examined. We identified the pentose/proton symporter, AraE, as the most effective transporter for both d xylose and l-arabinose in mesaconate production process. Further production optimization was achieved by operon screening and metabolic engineering. These efforts led to the engineered strains that produced 12.5g/l and 13.2g/l mesaconate after 48h from 20g/l of d-xylose and l-arabinose, respectively. Finally, the engineered strain overexpressing both l-arabinose and d-xylose operons produced 14.7g/l mesaconate from a 1:1 d-xylose and l-arabinose mixture with a yield of 85% of the theoretical maximum. (0.87g/g). This work demonstrates an effective system that converts pentoses into a value-added chemical, mesaconate, with promising titer, rate, and yield. PMID- 27697563 TI - Development of a Bacillus subtilis cell-free transcription-translation system for prototyping regulatory elements. AB - Cell-free transcription-translation systems were originally applied towards in vitro protein production. More recently, synthetic biology is enabling these systems to be used within a systematic design context for prototyping DNA regulatory elements, genetic logic circuits and biosynthetic pathways. The Gram positive soil bacterium, Bacillus subtilis, is an established model organism of industrial importance. To this end, we developed several B. subtilis-based cell free systems. Our improved B. subtilis WB800N-based system was capable of producing 0.8uM GFP, which gave a ~72x fold-improvement when compared with a B. subtilis 168 cell-free system. Our improved system was applied towards the prototyping of a B. subtilis promoter library in which we engineered several promoters, derived from the wild-type Pgrac (sigmaA) promoter, that display a range of comparable in vitro and in vivo transcriptional activities. Additionally, we demonstrate the cell-free characterisation of an inducible expression system, and the activity of a model enzyme - renilla luciferase. PMID- 27697564 TI - Continuous Home Care Reduces Hospice Disenrollment and Hospitalization After Hospice Enrollment. AB - CONTEXT: Among the four levels of hospice care, continuous home care (CHC) is the most expensive care, and infrequently provided in practice. OBJECTIVES: To identify hospice and patient characteristics associated with the use of CHC and to examine the associations between CHC utilization and hospice disenrollment or hospitalization after hospice enrollment. METHODS: Using 100% fee-for-service Medicare claims data for beneficiaries aged 66 years or older who died between July and December 2011, we identified the percentage of hospice agencies in which patients used CHC in 2011 and determined hospice and patient characteristics associated with the use of CHC. Using multivariable analyses, we examined the associations between CHC utilization and hospice disenrollment and hospitalization after hospice enrollment, adjusted for hospice and patient characteristics. RESULTS: Only 42.7% of hospices (1533 of 3592 hospices studied) provided CHC to at least one patient during the study period. Patients enrolled with for-profit, larger, and urban located hospices were more likely to use CHC (P < 0.001). Within these 1533 hospices, only 11.4% of patients used CHC. Patients who were white, had cancer, and had more comorbidities were more likely to use CHC. In multivariable models, compared with patients who did not use CHC, patients who used CHC were less likely to have hospice disenrollment (adjusted odds ratio 0.21; 95% CI 0.19, 0.23) and less likely to be hospitalized after hospice enrollment (adjusted odds ratio 0.37; 95% CI 0.34, 0.40). CONCLUSION: Although a minority of patients uses CHC, such services may be protective against hospice disenrollment and hospitalization after hospice enrollment. PMID- 27697566 TI - Hospice Value-Based Purchasing Program: A Model Design. AB - With the implementation of the Affordable Care Act, the U.S. government committed to a transition in payment policy for health care services linking reimbursement to improved health outcomes rather than the volume of services provided. To accomplish this goal, the Department of Health and Human Services is designing and implementing new payment models intended to improve the quality of health care while reducing its cost. Collectively, these novel payment models and programs have been characterized under the moniker of value-based purchasing (VBP), and although many of these models retain a fundamental fee-for-service (FFS) structure, they are seen as essential tools in the evolution away from volume-based health care financing toward a health system that provides "better care, smarter spending, and healthier people." In 2014, approximately 20% of Medicare provider FFS payments were linked to a VBP program. The Department of Health and Human Services has committed to a four-year plan to link 90% of Medicare provider FFS payments to value-based purchasing by 2018. To achieve this goal, all items and services currently reimbursed under Medicare FFS programs will need to be evaluated in the context of VBP. To this end, the Medicare Hospice benefit appears to be appropriate for inclusion in a model of VBP. This policy analysis proposes an adaptable model for a VBP program for the Medicare Hospice benefit linking payment to quality and efficiency in a manner consistent with statutory requirements established in the Affordable Care Act. PMID- 27697565 TI - Gender and Racial Differences in Stress, Coping, and Health-Related Quality of Life in Chronic Kidney Disease. AB - CONTEXT: Living with chronic kidney disease can be stressful and influence an individual's health-related quality of life. Effective coping strategies may reduce stress and improve quality of life in individuals with chronic medical conditions. OBJECTIVES: Health-related quality of life (HRQOL) is an important outcome for patients living with chronic kidney disease (CKD), and it is necessary to better understand potential gender and racial differences and predictors associated with reduced HRQOL, so that effective interventions can be developed. METHODS: Participants included 182 patients with CKD who were administered a battery of questions that included the Medical Outcomes Study Short-Form 36, Perceived Stress Scale, and the Brief COPE. Demographic and disease-specific information was abstracted from the patients' medical record. RESULTS: No differences by race were observed with regard to stress, quality of life, or coping with the exception that minority patients reported use of religious coping more often (P = 0.001) and had higher levels of energy compared with nonminority patients with CKD (P = 0.27). Women with CKD tended to use self distraction (P = 0.002), positive reframing (P = 0.035), venting (P = 0.024), and religious coping (P = 0 < 0.001) more often than men. No significant differences in perceived stress or domains of quality of life were observed between men and women with CKD. A link between coping strategies and HRQOL was observed in women (P = 0.001-0.02) but not men. Perceived stress was associated with poorer quality of life for men (P = 0.017 to <0.001) and women (P = 0.001 to <0.001), but more domains of men's quality of life were affected by perceived stress compared with women. CONCLUSIONS: The findings of the study suggest that the wider range of coping strategies used by women may be associated with buffering the link between perceived stress and quality of life. Men with CKD may benefit from interventions that not only reduce stress but also facilitate the use of a broader range of coping strategies to reduce stress and improve quality of life. PMID- 27697568 TI - Somatostatin Analogues Compared With Placebo and Other Pharmacologic Agents in the Management of Symptoms of Inoperable Malignant Bowel Obstruction: A Systematic Review. AB - CONTEXT: Somatostatin analogues are commonly used to relieve symptoms in malignant bowel obstruction (MBO) but are more expensive than other antisecretory agents. OBJECTIVES: To evaluate the evidence of effectiveness of somatostatin analogues compared with placebo and/or other pharmacologic agents in relieving vomiting in patients with inoperable MBO. METHODS: MEDLINE, EMBASE, CINAHL, and The Cochrane Controlled Trials Register databases were systematically searched; reference lists of relevant articles were hand searched. Cochrane risk of bias tool was used. RESULTS: The search identified 420 unique studies. Seven randomized controlled trials (RCTs) met the inclusion criteria (six octreotide studies and one lanreotide); 220 people administered somatostatin analogues and 207 placebo or hyoscine butylbromide. Three RCTs compared a somatostatin analogue with placebo and four with hyoscine butylbromide. Two adequately powered multicenter RCTs with a low Cochrane risk of bias reported no significant difference between somatostatin analogues and placebo in their primary end points. Four RCTs with a high/unclear Cochrane risk of bias reported that somatostatin analogues were more effective than hyoscine butylbromide in reducing vomiting. CONCLUSION: There is low-level evidence of benefit with somatostatin analogues in the symptomatic treatment of MBO. However, high-level evidence from trials with low risk of bias found no benefit of somatostatin analogues for their primary outcome. There is debate regarding the clinically relevant study end point for symptom control in MBO and when it should be measured. The role of somatostatin analogues in this clinical situation requires further adequately powered, well-designed trials with agreed clinically important end points and measures. PMID- 27697567 TI - The Symptom Experience in Rectal Cancer Survivors. AB - CONTEXT: As the number of rectal cancer survivors grows, it is important to understand the symptom experience after treatment. Although data show that rectal cancer survivors experience a variety of symptoms after diagnosis, little has been done to study the way these symptoms are grouped and associated. OBJECTIVES: To determine symptom prevalence and intensity in rectal cancer survivors and if clusters of survivors exist, who share similar symptom-defined survivor subgroups that may vary based on antecedent variables. METHODS: A secondary analysis of the Cancer Care and Outcomes Research and Surveillance database was undertaken. Cluster analysis was performed on 15-month postdiagnosis data to form post treatment survivor subgroups, and these were examined for differences in demographic and clinical characteristics. Data were analyzed using cluster analysis, chi-square, and analysis of variance. RESULTS: A total of 275 rectal cancer survivors were included who had undergone chemotherapy, radiation therapy, and surgery. Most frequently reported symptoms included feeling "worn out" (87%), feeling "tired" (85%), and "trouble sleeping" (66%). Four symptom-defined survivor subgroups (minimally symptomatic n = 40, tired and trouble sleeping n = 138, moderate symptoms n = 42, and highly symptomatic n = 55) were identified with symptom differences existing among each subgroup. Age and being married/partnered were the only two antecedents found to differ across subgroups. CONCLUSION: This study documents differences in the symptom experience after treatment. The identification of survivor subgroups allows researchers to further investigate tailored, supportive care strategies to minimize ongoing symptoms in those with the greatest symptom burden. PMID- 27697569 TI - Performance of Consultative Palliative Care Model in Achieving Quality Metrics in the ICU. AB - CONTEXT: Quality metrics for intensive care unit (ICU)-based palliative care have been proposed, but it is unknown how consultative palliative care can contribute to performance on these measures. OBJECTIVES: Assess adherence to proposed quality metrics of ICU-based palliative care by palliative care specialists. METHODS: Surrogates for 9/14 patient-level quality metrics were assessed in all patients who received an initial palliative care specialist consult while in an ICU from 10/26/2012 to 1/16/2015 in the Global Palliative Care Quality Alliance, a nationwide palliative care quality registry. RESULTS: Two hundred fifty-four patients received an initial palliative care consultation in an ICU setting. Mean (SD) age was 67.5 (17.3) years, 52% were female. The most common reasons for consultation were symptom management (33%) and end-of-life transition (24%). Adherence to ICU quality metrics for palliative care was variable: clinicians documented presence or absence of advance directives in 36% of encounters, assessed pain in 52.0%, dyspnea in 50.8%, spiritual support in 62%, and reported an intervention for pain in 100% of patients with documented moderate to severe intensity pain. CONCLUSION: Palliative care consultations in an ICU setting are characterized by variable adherence to candidate ICU palliative care quality metrics. Although symptom management was the most common reason for palliative care consultation, consultants infrequently documented symptom assessments. Palliative care consultants performed better in offering spiritual support and managing documented symptoms. These results highlight specific competencies of consultative palliative care that should be complimented by ICU teams to ensure high-quality comprehensive care for the critically ill. PMID- 27697570 TI - Metabolomic profiling of doxycycline treatment in chronic obstructive pulmonary disease. AB - Serum metabolic profiling can identify the metabolites responsible for discrimination between doxycycline treated and untreated chronic obstructive pulmonary disease (COPD) and explain the possible effect of doxycycline in improving the disease conditions. 1H nuclear magnetic resonance (NMR)-based metabolomics was used to obtain serum metabolic profiles of 60 add-on doxycycline treated COPD patients and 40 patients receiving standard therapy. The acquired data were analyzed using multivariate principal component analysis (PCA), partial least-squares-discriminant analysis (PLS-DA), and orthogonal projection to latent structure with discriminant analysis (OPLS-DA). A clear metabolic differentiation was apparent between the pre and post doxycycline treated group. The distinguishing metabolites lactate and fatty acids were significantly down regulated and formate, citrate, imidazole and l-arginine upregulated. Lactate and folate are further validated biochemically. Metabolic changes, such as decreased lactate level, inhibited arginase activity and lowered fatty acid level observed in COPD patients in response to add-on doxycycline treatment, reflect the anti inflammatory action of the drug. Doxycycline as a possible therapeutic option for COPD seems promising. PMID- 27697571 TI - Development and validation of a stability-indicating HPLC-UV method for the determination of Thiocolchicoside and its degradation products. AB - A stability indicating high performance liquid chromatography method has been developed for the determination of thiocolchicoside (TCC) and its main degradation products thiocolchicoside S-oxide (D1SO) and 3-O demethylthiocolchicine (D3) in liquid and solid formulations. The method was developed based on a previous forced degradation study showing that TCC underwent chemical degradation by acid/base catalyzed hydrolysis and oxidation being the main degradation products D3 and D1SO respectively. The analytes separation and quantification were achieved on a SynergiTM 4MUm Polar-RP 80A, column 150*4.6mm (Phenomenex) using the mobile phase constituted (flow rate 1mLmin-1) of eluant A: 20mM sodium acetate buffer (pH 5.0) and eluant B: MeOH:CH3CN (20:80); the elution was performed in gradient mode detecting the analytes at 254nm. The method showed linearity for TCC assay in the 5-15MUgmL-1, range and for unknown (TCCfu) and known (D1SO and D3) degradation products assay, in the 0.5-10MUgmL-1 range: all the square of the correlation coefficients were greater than 0.999. The precision, determined in terms of intra-day and inter-day were expressed as RSDs and resulted to be 1.19, 1.10, 1.37 and 1.04% and 0.95, 0.83, 1.30 and 0.72 for TCC, TCCfu, D1SO and D3, respectively. The method demonstrated also to be accurate; indeed, the average recoveries were 102.1/102.0% for TCC (ampoules and hard capsules respectively), 101.3/100.3% for TCCfu, 101.7/100.2% for D1SO, and 101.4/101.4% for D3. The robustness was also evaluated by variations of mobile phase composition and pH. Finally, the applicability of the method was evaluated by analysis of commercial liquid and solid dosage forms. PMID- 27697572 TI - Dried blood spot analysis of gabapentin as a valid alternative for serum: a bridging study. AB - We evaluated the applicability of a validated GC-MS method for the determination of gabapentin in dried blood spots (DBS). Important for the acceptance of DBS sampling as an alternative sampling strategy is the possibility to base solid conclusions on the quantification. Therefore, bridging studies -studies in which the correlation between both DBS and a reference matrix (e.g. serum) is evaluated statistically- need to be conducted. To this end, a comparative study was set up to quantify gabapentin in both blood (DBS) and serum samples. Statistically significant differences between DBS and serum concentrations were found (p<0.001). A mean blood-to-serum ratio of 0.85 was observed, which is in line with expectations. Calculated serum concentrations (obtained by dividing the DBS concentrations by 0.85) demonstrated a good correlation with measured serum concentrations, with 87% of samples fulfilling the criterion for incurred sample reanalysis. Furthermore, our data indicate a good correlation between capillary and venous concentrations. Conclusively, this study demonstrated that DBS are a valid alternative to serum for the determination of gabapentin. PMID- 27697573 TI - NMR-based metabonomics and correlation analysis reveal potential biomarkers associated with chronic atrophic gastritis. AB - Chronic atrophic gastritis (CAG) is one of the most important pre-cancerous states with a high prevalence. Exploring of the underlying mechanism and potential biomarkers is of significant importance for CAG. In the present work, 1H NMR-based metabonomics with correlative analysis was performed to analyze the metabolic features of CAG. 19 plasma metabolites and 18 urine metabolites were enrolled to construct the circulatory and excretory metabolome of CAG, which was in response to alterations of energy metabolism, inflammation, immune dysfunction, as well as oxidative stress. 7 plasma biomarkers and 7 urine biomarkers were screened to elucidate the pathogenesis of CAG based on the further correlation analysis with biochemical indexes. Finally, 3 plasma biomarkers (arginine, succinate and 3-hydroxybutyrate) and 2 urine biomarkers (alpha-ketoglutarate and valine) highlighted the potential to indicate risks of CAG in virtue of correlation with pepsin activity and ROC analysis. Here, our results paved a way for elucidating the underlying mechanisms in the development of CAG, and provided new avenues for the diagnosis of CAG and presented potential drug targets for treatment of CAG. PMID- 27697574 TI - Combination of HPLC-MS and QAMS as a new analytical approach for determination of saponins in ginseng containing products. AB - Conventional liquid chromatographic methods coupled with ultraviolet detection with low-wavelength range are lacking selectivity and sensitivity to determine both polar and less polar ginsenosides. Also the lack of standard substances for such quality control methods is leading to development of the approaches using single standard for quantitative analysis of multi-component system (QAMS). The objective of present study was to establish and compare for the first time liquid chromatography-ultraviolet detection and liquid chromatography-mass spectrometry QAMS methods for the simultaneous determination of protopanaxatriol-type and protopanaxadiol-type ginsenosides in a variety of ginseng products. Sixteen polar and less polar ginsenosides were separated on a reversed-phase C18-column (150mm*2.0mm, 2.2MUm) with a mobile phase consisting of 0.1% formic acid in water and acetonitrile. Components were then detected by means of ultraviolet and mass spectrometry detection. Characteristic sapogenin fragmentation signals with m/z 423 and 425 for two major groups of ginseng saponins allowed their simultaneous determination in a single chromatographic run, while the use of ultraviolet detection tends to give overvalued results. Structural correlation between the relative response factors and saponin structure was demonstrated. The method was linear (R2 >0.999) and sensitive (LODs, 0.01-0.03mg/mL) within the concentration range tested. Concentrations of individual ginsenosides and several quality control parameters were determined in ginseng root extracts and commercial ginseng products of different types (root slices, tablets and tea samples), and results showed that ginsenoside content can be successfully measured by means of QAMS approach. PMID- 27697575 TI - An integrated strategy for establishment of curcuminoid profile in turmeric using two LC-MS/MS platforms. AB - Turmeric and curcuminoids are used as natural food coloring and functional food additives in various parts of the world. In this study, ninety-six curcuminoids were fully characterized using a targeted curcuminoid profile, which established by integrated use of two complementary LC-MS/MS platforms (liquid chromatography quadrupole time of flight mass spectrometry (LC-QTOF-MS/MS) and liquid chromatography-quadrupole linear ion trap mass spectrometry (LC-QTRAP-MS/MS)). The curcuminoid profile was represented in the form of a multiple reaction monitoring (MRM) mode based on LC-QTRAP-MS/MS analysis. It facilitated the qualitative and relative quantitative analysis of curcuminoids in a single injection. Meanwhile, the profile was successfully applied to the quality evaluation of raw materials of turmeric from different regions in China and Myanmar. The structural identification procedures of curcuminoids and the integrated strategy provide a suitable method to analyze targeted plant metabolites which occur in a high number but sharing either structural similarities or similar functional groups. PMID- 27697576 TI - Testicular Torsion Presentation Trends before and after Pediatric Urology Subspecialty Certification. AB - PURPOSE: We examined testicular torsion presentation and referral trends at our institution before and after pediatric urology subspecialty certification. MATERIALS AND METHODS: We reviewed patients with testicular torsion presenting directly to our pediatric hospital emergency department ("direct") or transferred urgently from an outside institution ("referred") who underwent detorsion and orchiopexy or orchiectomy between 2005 and 2015. Presentations were considered acute (less than 24 hours) or delayed (24 hours or greater) based on time from symptom onset. Primary outcomes were case volume and presentation trends through time. Secondary outcomes were effect of presenting location and transport variables on orchiectomy rate. RESULTS: Incidence of testicular torsion increased from 15 cases in 2005 to 32 in 2015. Annual incidence of direct cases increased slightly during the study period from 12 to 17, whereas incidence of referred cases increased from 3 in 2005 to 15 in 2015. Proportion of referred acute cases markedly increased from precertification (4 of 63, 6.3%) to postcertification period (42 of 155, 27.1%; p <0.01). The majority of referred cases (59 of 83, 71.1%) presented during weekday nights or weekends compared to a minority of direct cases (59 of 135, 43.7%; p <0.01). Orchiectomy rates were similar between direct and referred cases across all study periods and were not significantly impacted by presentation location, transport distance or transport modality (all p >0.05). CONCLUSIONS: Patients with testicular torsion have been increasingly referred to our institution, with the majority presenting on weekday nights and weekends. Our data do not support routinely transferring these patients to dedicated pediatric hospitals. PMID- 27697577 TI - Association of Sleep Disordered Breathing with Erectile Dysfunction in Community Dwelling Older Men. AB - PURPOSE: We investigated the association between sleep disordered breathing and erectile dysfunction in older men. MATERIALS AND METHODS: We performed a cross sectional analysis of community dwelling men age 67 years or older enrolled in the Osteoporotic Fractures in Men Sleep Study. Participants underwent overnight polysomnography (2003 to 2005) and completed sexual health questionnaires (2005 to 2006). We defined sleep disordered breathing using the apnea-hypopnea index or nocturnal hypoxemia. Erectile dysfunction was defined using the MMAS (Massachusetts Male Aging Study) scale and, in sexually active men, the International Index of Erectile Function. We used logistic regression to examine the association between sleep disordered breathing and erectile dysfunction. RESULTS: Mean participant age was 76+/-5 years. Of the 2,676 men completing the MMAS, 70% had moderate to complete erectile dysfunction. Among 1,099 sexually active men completing the IIEF-5 (5-item International Index of Erectile Function), 26% had moderate to severe erectile dysfunction. A higher apnea hypopnea index was associated with greater odds of MMAS defined moderate to complete erectile dysfunction after adjusting for age and study site (OR 1.39, 95% CI 1.00-1.92 for severe sleep disordered breathing vs none, p trend=0.008), but not after further adjustment for body mass index, socioeconomic status and comorbidities (OR 1.05, 95% CI 0.75-1.49, p trend=0.452). Greater nocturnal hypoxemia was associated with increased odds of MMAS defined moderate to complete erectile dysfunction (unadjusted OR 1.36, 95% Cl 1.04-1.80 vs none) but this was attenuated after adjustment for age and study site (OR 1.24, 95% CI 0.92-1.66). Sleep disordered breathing was not associated with erectile dysfunction by 5-item International Index of Erectile Function. CONCLUSIONS: In this cross-sectional analysis in older men sleep disordered breathing was associated with higher odds of erectile dysfunction in unadjusted analyses that was largely explained by higher body mass index and increased comorbidity among men with sleep disordered breathing. Prospective studies accounting for obesity and multimorbidity would further clarify the association of sleep disordered breathing and erectile dysfunction. PMID- 27697579 TI - Improving Organ Salvage in Testicular Torsion: Comparative Study of Patients Undergoing vs Not Undergoing Preoperative Manual Detorsion. AB - PURPOSE: We compared surgical outcomes between patients undergoing and those not undergoing preoperative manual detorsion for intravaginal testicular torsion. MATERIALS AND METHODS: We retrospectively analyzed consecutive patients treated surgically for testicular torsion who were examined within 24 hours of symptoms at our emergency department between January 2012 and September 2015. Explanatory variables were age, presentation delay (time between symptoms and urological examination), surgical wait time (time from examination to surgery), and whether manual detorsion was attempted and, if attempted, was declared successful. End points were surgical outcome (orchiopexy, orchiectomy) and testicular rotation at surgery. Statistical analysis included nonparametric tests and logistic regression. Statistical significance and confidence intervals were set at p <0.05 and 0.95, respectively. RESULTS: Detorsion was attempted in 76 of 133 cases (57.1%) and was successful in 72 (95.1%). Patient age (median 15.6 vs 17.4 years, p = 0.115), presentation delay (6.6 vs 6.3 hours, p = 1.0) and surgical wait time (3.5 vs 3.2 hours, p = 0.412) were comparable between patients who underwent manual detorsion attempt and those who did not. Testicular rotation was less among successfully detorsed patients. Orchiectomy was performed in 2 of 72 successfully detorsed patients (2.8%), compared to 15 of 61 patients (24.6%) in whom detorsion was not attempted or was unsuccessful (OR 11.23, p = 0.0002). Logistic regression indicated that surgical wait time (OR 0.95, p = 0.002) and successful detorsion (OR 17.38, p = 0.001) were independently associated with orchiopexy. CONCLUSIONS: Preoperative manual detorsion was associated with improved surgical salvage in patients with testicular torsion. PMID- 27697578 TI - Expression of Programmed Death Ligand 1 in Penile Cancer is of Prognostic Value and Associated with HPV Status. AB - PURPOSE: PD-L1 (programmed death ligand 1) inhibits T-cell function and prevents tumor eradication. This is facilitated by PD-L1 positive tumor cells and PD-L1 positive immune cells, and can be prevented by anti-PD-1 (programmed death 1)/PD L1 immunotherapy. In advanced penile cancer there is a need for new therapeutic strategies. We investigated PD-L1 expression in penile cancers and compared PD-L1 expression with disease specific survival, lymph node metastases at diagnosis and high risk HPV status in a large patient cohort. MATERIALS AND METHODS: A total of 213 primary tumors were immunohistochemically stained for PD-L1 and scored for tumor (percentage), stroma (binary) and PD-L1 positive tumor infiltrating macrophages. Additionally, PD-L1 positive tumors were scored for expression pattern, that is diffuse or predominantly present at the tumor-stroma margin. RESULTS: Staining was successful in 200 tumors, of which 75% were high risk HPV negative. Median followup was 62 months. Of 200 tumors 96 (48%) were PD-L1 positive (scored 1% or greater), of which 59 (62%) had a marginal expression pattern and 79 (82%) were high risk HPV negative (p = 0.03). Compared to PD-L1 negative tumors, the PD-L1 expression patterns had different prognostic values in the whole cohort as well as in the high risk HPV negative subgroup. On multivariable analyses a marginal expression pattern was associated with absent lymph node metastases (OR 0.4) while diffuse expression was associated with poor survival (HR 2.58). These results were more prominent in the high risk HPV negative subgroup (OR 0.25, HR 3.92). CONCLUSIONS: PD-L1 was expressed in 48% of penile carcinomas and mainly in high risk HPV negative tumors. The pattern of expression was a prognostic factor as marginal expression was associated with absent lymph node metastases and diffuse expression was associated with poor survival. PMID- 27697580 TI - Nanoknife Electroporation Ablation Trial: A Prospective Development Study Investigating Focal Irreversible Electroporation for Localized Prostate Cancer. AB - PURPOSE: Irreversible electroporation has attractive attributes for focal ablation, namely nonthermal effect, precise demarcation of treatment and tissue selectivity. We report a prospective development study investigating focal irreversible electroporation. MATERIALS AND METHODS: A total of 20 men with certain characteristics were recruited for study, including a visible index lesion on anterior magnetic resonance imaging that was concordant with transperineal targeted and template prostate mapping biopsy, absent clinically significant disease noted elsewhere (University College London definition 2) and prostate specific antigen 15 ng/ml or less. Our primary objective was to determine the side effect profile at 12 months. Secondary objectives included the domain specific toxicity profile using patient reported outcomes and early disease control using magnetic resonance imaging targeted biopsy. RESULTS: A total of 19 patients with median age of 60 years (IQR 53-66) and median prostate specific antigen 7.75 ng/ml (IQR 5.5-10.03) were treated. Of the patients 16 were available for estimating the first outcome as 1 was lost to followup and 2 had received another form of treatment by study end. All 16 men had pad-free/leak free continence at 12 months. The proportion of men with erection sufficient for penetration decreased from 12 of 16 (75%) to 11 of 16 (69%). No serious adverse events were recorded. There was a statistically significant improvement in urinary symptoms according to changes in UCLA-EPIC (UCLA Expanded Prostate Cancer Index Composite) and I-PSS (International Prostate Symptom Score) (p = 0.039 and 0.001, respectively). Erectile function remained stable according to the change in IIEF-15 (15-Item International Index of Erectile Function) (p = 0.572). Median prostate specific antigen significantly decreased to 1.71 ng/ml (p = 0.001). One man refused followup biopsy. No residual disease was found in 11 patients (61.1%). One man (5.6%) harbored clinically insignificant disease and the remaining 6 (33.3%) harbored clinically significant disease. CONCLUSIONS: Focal irreversible electroporation has low genitourinary toxicity. Additional studies are needed to optimize patient selection and treatment parameters.

AB - INTRODUCTION: This phase I trial was conducted to determine the safety, maximum tolerated dose (MTD)/recommended phase II dose, and efficacy of crizotinib plus erlotinib in patients with advanced NSCLC. METHODS: Patients with NSCLC and an Eastern Cooperative Oncology Group performance status of 0 to 2 after failure of one or two prior chemotherapy regimens were eligible. Erlotinib, 100 mg, was given continuously once daily starting between day -14 and -7; crizotinib, 200 mg twice daily (dose level 1) or 150 mg twice daily (dose level -1), was added continuously beginning on day 1 of treatment cycle 1. Potential pharmacokinetic interactions between crizotinib and erlotinib were evaluated. RESULTS: Twenty seven patients received treatment; 26 received crizotinib plus erlotinib. Frequent adverse events were diarrhea, rash, decreased appetite, and fatigue. Dose-limiting toxicities were dehydration, diarrhea, dry eye, dysphagia, dyspepsia, esophagitis and vomiting. The MTD was crizotinib, 150 mg twice daily, with erlotinib, 100 mg once daily. Crizotinib increased the erlotinib area under the concentration-time curve 1.5-fold (dose level -1) and 1.8-fold (dose level 1). The plasma level of crizotinib appeared to be unaffected by coadministration of erlotinib. Two patients whose tumors harbored activating EGFR mutations achieved confirmed partial responses, one at each crizotinib dose level. CONCLUSIONS: The MTD of the combination of crizotinib and erlotinib in patients with advanced NSCLC was crizotinib, 150 mg twice daily, with erlotinib, 100 mg once daily, which is less than the approved dose of either agent. The phase II portion of the study was not initiated. PMID- 27697582 TI - Risk of caries adjacent to different restoration materials: Systematic review of in situ studies. AB - OBJECTIVES: The risk of 'caries adjacent to restorations' (CAR) might depend on the used restorative materials. In situ studies are often used to compare the risk of caries adjacent to different materials. We aimed to review in situ studies to evaluate how different materials contribute to risk of CAR. DATA SOURCES: We included in situ controlled trials comparing directly placed restorative materials, reporting on caries (mineral loss, measured via radiography or micro-hardness) adjacent to these materials. Medline, Embase and Cochrane CENTRAL were systematically searched. Screening and data extraction was performed independently by two authors. Materials were classified according to the used adhesive and restorative materials. Fixed-effects pairwise and frequentistic network meta-analyses were performed STUDY SELECTION: Nine studies (132 patients, 8 materials) were included, yielding inconsistent results. We could not identify underlying reasons, as confounders were only limitedly reported. The resulting material rankings come with great uncertainty, and raise doubts as to the validity and transferability of in situ studies as well as the applicability of their findings. CONCLUSIONS: The current body of evidence of in situ studies is insufficient for firm conclusions as to the caries risk adjacent to different materials. The validity and applicability of included studies remain uncertain. CLINICAL SIGNIFICANCE: While single in situ studies seem to convey consistent and applicable information, the overall body of evidence is inconsistent, limiting the conclusions which can be drawn from it. PMID- 27697583 TI - Speech onset enhancement improves intelligibility in adverse listening conditions for cochlear implant users. AB - Speech perception by cochlear implant (CI) users can be very good in quiet but their speech intelligibility (SI) performance decreases in noisy environments. Because recent studies have shown that transient parts of the speech envelope are most important for SI in normal-hearing (NH) listeners, the enhanced envelope (EE) strategy was developed to emphasize onset cues of the speech envelope in the CI signal processing chain. The influence of enhancement of the onsets of the speech envelope on SI was investigated with CI users for speech in stationary speech-shaped noise (SSN) and with an interfering talker. All CI users showed an immediate benefit when a priori knowledge was used for the onset enhancement. A SI improvement was obtained at signal-to-noise ratios (SNRs) below 6 dB, corresponding to a speech reception threshold (SRT) improvement of 2.1 dB. Furthermore, stop consonant reception was improved with the EE strategy in quiet and in SSN at 6 dB SNR. For speech in speech, the SRT improvements were 2.1 dB and 1 dB when the onsets of the target speaker with a priori knowledge of the signal components or of the mixture of the target and the interfering speaker were enhanced, respectively. The latter demonstrates that a small benefit can be obtained without a priori knowledge. PMID- 27697584 TI - Perinatal exposure to bisphenol A modifies the transcriptional regulation of the beta-Casein gene during secretory activation of the rat mammary gland. AB - With the aim to analyze whether bisphenol A (BPA) modifies beta-Casein (beta-Cas) synthesis and transcriptional regulation in perinatally exposed animals, here, pregnant F0 rats were orally exposed to 0, 0.6 or 52 MUg BPA/kg/day from gestation day 9 until weaning. Then, F1 females were bred and mammary glands were obtained on lactation day 2. Perinatal BPA exposure decreased beta-Cas expression without modifying the activation of prolactin receptor. It also decreased the expression of glucocorticoid receptor in BPA52-exposed dams and beta1 and alpha6 integrins as well as dystroglycan in both BPA groups. In addition, BPA exposure altered the expression of histone-modifying enzymes and induced histone modifications and DNA methylation in the promoter, enhancer and exon VII of the beta-Cas gene. An impaired crosstalk between the extracellular matrix and lactogenic hormone signaling pathways and epigenetic modifications of the beta Cas gene could be the molecular mechanisms by which BPA decreased beta-Cas expression.

PMID- 27697585 TI - Human Herpesvirus 6 Infection Following Haploidentical Transplantation: Immune Recovery and Outcome. AB - Human herpesvirus 6 (HHV-6) is increasingly recognized as a potentially life threatening pathogen in allogeneic hematopoietic stem cell transplantation (alloSCT). We retrospectively evaluated 54 adult patients who developed positivity to HHV-6 after alloSCT. The median time from alloSCT to HHV-6 reactivation was 34 days. HHV-6 was present in plasma samples from 31 patients, in bone marrow (BM) of 9 patients, in bronchoalveolar lavage fluid and liver or gut biopsy specimens from 33 patients, and in cerebrospinal fluid of 7 patients. Twenty-nine patients developed acute graft-versus-host disease (GVHD), mainly grade III-IV, and 15 had concomitant cytomegalovirus reactivation. The median absolute CD3+ lymphocyte count was 207 cells/uL. We reported the following clinical manifestations: fever in 43 patients, skin rash in 22, hepatitis in 19, diarrhea in 24, encephalitis in 10, BM suppression in 18, and delayed engraftment in 11. Antiviral pharmacologic treatment was administered to 37 patients; nonetheless, the mortality rate was relatively high in this population (overall survival [OS] at 1 year, 38% +/- 7%). A better OS was significantly associated with a CD3+ cell count >=200/uL at the time of HHV-6 reactivation (P = .0002). OS was also positively affected by the absence of acute GVHD grade III-IV (P = .03) and by complete disease remission (P = .03), but was not significantly influenced by steroid administration, time after alloSCT, type of antiviral prophylaxis, plasma viral load, or organ involvement. Although HHV-6 detection typically occurred early after alloSCT, better T cell immune reconstitution seems to have the potential to improve clinical outcomes. Our findings provide new insight into the interplay between HHV-6 and the transplanted immune system. PMID- 27697587 TI - Reversal of schizophrenia-like symptoms and immune alterations in mice by immunomodulatory drugs. AB - Immune dysregulation observed in schizophrenia alters tryptophan metabolism. Tryptophan metabolism is triggered by indoleamine 2,3-dioxygenase (IDO) and tryptophan 2,3-dioxygenase (TDO). Tryptophan is converted to quinolinic acid, a potent neurotoxin, and to kynurenic acid, an NMDA antagonist. 1-Methyl-D tryptophan (MDT) inhibits IDO. Melatonin is metabolized by IDO while inhibiting TDO. We evaluated the reversal of ketamine-induced schizophrenia-like behavioral and neurochemical alterations in mice by the administration of MDT (20 or 40 mg/kg, i.p.) or melatonin (15 mg/kg, per os). Oxidative stress and inflammatory alterations, i.e. myeloperoxidase activity (MPO), reduced glutathione (GSH), lipid peroxidation (LPO) and interleukin (IL)-4 and IL-6 were measured in the prefrontal cortex (PFC), hippocampus and striatum. Risperidone was used as standard antipsychotic. Ketamine triggered positive- (PPI deficits and hyperlocomotion), cognitive- (working memory deficits) and negative (social interaction deficits) schizophrenia-like symptoms. These symptoms were accompanied by increased MPO activity, decreased GSH and increased LPO in all brain areas and increments in hippocampal IL-4 and IL-6. MDT and melatonin reversed all ketamine-induced behavioral alterations. Risperidone did not reverse working memory deficits. MDT and melatonin reversed alterations in MPO activity and GSH levels. LP was reversed only by melatonin and risperidone. Risperidone could not reverse MPO alterations in the PFC and striatum. All drugs reversed the alterations in IL-4 and IL-6. The hippocampus and striatum of ketamine+melatonin treated animals had lower levels of IL-6. Our findings provide further preclinical evidence that immune-inflammatory and oxidative pathways are involved in schizophrenia and that targeting these pathways is a valid treatment option in schizophrenia. PMID- 27697588 TI - Metachronous anaplastic sarcoma of the kidney and thyroid follicular carcinoma as manifestations of DICER1 abnormalities. AB - Anaplastic sarcoma of the kidney (ASK) is a tumor found in the pediatric age group and shows many histopathological similarities to pleuropulmonary blastoma (PPB). We present a 12-year-old girl diagnosed with ASK and, 3 years later, with thyroid follicular carcinoma (TFC) with DICER1 abnormalities. Germline insertion/deletion (p. G1809_S1814delinsA) and independent somatic mutations (p. E1705K in ASK, p. E1813D in TFC) were identified. All of these abnormalities are in the catalytic domain of RNase IIIb. Single-nucleotide polymorphism genotyping microarray revealed independent copy number alterations (trisomy 8, monosomy 10, loss of 17p, and partial gain of 17q in ASK; trisomy 5 and partial loss of Xq in TFC). The copy number alteration pattern of ASK was similar to the pattern previously reported in PPB. The present case implies that ASK is a renal counterpart of PPB and that ASK with DICER1 abnormalities should be suspected in a broader age group than PPB. PMID- 27697590 TI - A prediction model for spontaneous regression of cervical intraepithelial neoplasia grade 2, based on simple clinical parameters. AB - This study aims to develop a prediction model for spontaneous regression of cervical intraepithelial neoplasia grade 2 (CIN 2) lesions based on simple clinicopathological parameters. The study was conducted at Maastricht University Medical Center, the Netherlands. The prediction model was developed in a retrospective cohort of 129 women with a histologic diagnosis of CIN 2 who were managed by watchful waiting for 6 to 24months. Five potential predictors for spontaneous regression were selected based on the literature and expert opinion and were analyzed in a multivariable logistic regression model, followed by backward stepwise deletion based on the Wald test. The prediction model was internally validated by the bootstrapping method. Discriminative capacity and accuracy were tested by assessing the area under the receiver operating characteristic curve (AUC) and a calibration plot. Disease regression within 24months was seen in 91 (71%) of 129 patients. A prediction model was developed including the following variables: smoking, Papanicolaou test outcome before the CIN 2 diagnosis, concomitant CIN 1 diagnosis in the same biopsy, and more than 1 biopsy containing CIN 2. Not smoking, Papanicolaou class <3, concomitant CIN 1, and no more than 1 biopsy containing CIN 2 were predictive of disease regression. The AUC was 69.2% (95% confidence interval, 58.5%-79.9%), indicating a moderate discriminative ability of the model. The calibration plot indicated good calibration of the predicted probabilities. This prediction model for spontaneous regression of CIN 2 may aid physicians in the personalized management of these lesions. PMID- 27697589 TI - Increased plasmacytic differentiation in gastric mucosa-associated lymphoid tissue lymphomas: Helicobacter pylori eradication response and IgG4+ plasma cell association. AB - Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a rare extranodal marginal zone B-cell lymphoma that is often associated with plasmacytic differentiation. However, the clinicopathological characteristics of gastric MALT lymphoma with increased plasmacytic differentiation have not yet been studied. To assess the clinicopathological implications of gastric MALT lymphoma with increased plasmacytic differentiation, 36 cases with increased plasmacytic differentiation and a control group of 16 cases with minimal plasmacytic differentiation were retrospectively collected from 65 primary gastric MALT lymphomas (2010-2012). The hematoxylin and eosin slides were reviewed, and IgG, IgG4, and kappa and lambda immunohistochemical staining was performed. Clinicopathological differences between the 2 groups were compared using the chi2 test and odds ratios. Logistic regression analyses were used to evaluate resistance to Helicobacter pylori eradication therapy. Increased plasmacytic differentiation is significantly correlated with the H pylori eradication response (94.4% versus 66.7%, P=.018), lower frequency of relapse (5.6% versus 35.7%, P=.014), the presence of more than one IgG4+ cell per high-power field (27.8% versus 0%, P=.022), and light-chain restriction (33.3% versus 6.2%, P=.044). Univariable logistic regression indicated that negative H pylori status (P=.016) and minimal plasmacytic differentiation (P=.019) were statistically significant predictive factors for resistance to H pylori eradication. Multivariable logistic regression analyses identified no statistically significant predictive factors. However, H pylori negativity and minimal plasmacytic differentiation showed a statistical trend toward significance (P=.078 and P=.09). Gastric MALT lymphomas with increased plasmacytic differentiation have different clinicopathological characteristics, and plasmacytic differentiation is associated with H pylori eradication response. PMID- 27697591 TI - Lipopolysaccharide and IL-1beta coordinate a synergy on cytokine production by upregulating MyD88 expression in human gingival fibroblasts. AB - Both lipopolysaccharide (LPS) and interleukin (IL)-1beta activate the MyD88 dependent signaling pathways to stimulate proinflammatory cytokine expression. However, it remains unknown how LPS and IL-1beta interact with each other to coordinate the stimulation. In this study, we sought to investigate the interaction between LPS and IL-1beta on MyD88-dependent signaling pathways in human gingival fibroblasts (HGFs). Results showed that LPS derived from Porphyromonas gingivalis (Pg LPS) and IL-1beta cooperatively stimulated mitogen activated protein kinase (MAPK) and nuclear factor kappa B (NFkappaB) signaling pathways, and subsequent expression of proinflammatory cytokine expression. Furthermore, our results showed that Pg LPS and IL-1beta exerted a synergy on MyD88 expression and knockdown of MyD88 expression by small interfering RNA diminished the synergistic effect of Pg LPS and IL-1beta on IL-6 expression, suggesting that upregulation of MyD88 is involved in the coordinated stimulation by Pg LPS and IL-1beta of proinflammatory cytokine expression. Finally, our results showed that pharmacological inhibitors for MAPK and NFkappaB significantly reduced IL-6 secretion stimulated by Pg LPS and IL-1beta, indicating that the MyD88-dependent MAPK and NFkappaB signaling pathways are essential for the upregulation of proinflammatory cytokine expression by Pg LPS and IL-1beta. Taken together, this study showed that LPS and IL-1beta coordinate a synergy on cytokine production by upregulating MyD88 expression in HGFs. PMID- 27697592 TI - Suppressing Pitx2 inhibits proliferation and promotes differentiation of iHepSCs. AB - Induced hepatic stem cells (iHepSCs) have great potential as donors for liver cell therapy due to their abilities for self-renewal and bi-potential differentiation. However, the molecular mechanism regulating proliferation and differentiation of iHepSCs is poorly understood. In this study, we provide evidence that the homeodomain transcription factor, Pitx2, is essential to maintain iHepSCs stem cell characteristics. Suppressing Pitx2 expression in iHepSCs by lentivirus mediated specific shRNA markedly reduced the expression of the hepatic stem cell-associated genes (Lgr5, EpCAM, and Sox9) with concomitant inhibition of proliferation by blocking the G1/S phase transition, and these phenotypic changes were reversed upon re-expression of Pitx2. Pitx2 knockdown also resulted in up-regulation of the p53-induced Cdk inhibitor p21, and down regulation of its downstream effector CDK2-Cyclin E kinase complex. Furthermore, we observed that iHepSCs were more efficiently induced to differentiate into both hepatocytes and cholangiocytes when Pitx2 expression was suppressed, as compared to unmanipulated iHepSCs. These findings reveal that Pitx2 expression may be leveraged to control the status of iHepSCs during expansion in vitro to provide a strategy for further application of iHepSCs in liver cell therapy. PMID- 27697593 TI - What's the gist? The influence of schemas on the neural correlates underlying true and false memories. AB - The current study used a novel scene paradigm to investigate the role of encoding schemas on memory. Specifically, the study examined the influence of a strong encoding schema on retrieval of both schematic and non-schematic information, as well as false memories for information associated with the schema. Additionally, the separate roles of recollection and familiarity in both veridical and false memory retrieval were examined. The study identified several novel results. First, while many common neural regions mediated both schematic and non-schematic retrieval success, schematic recollection exhibited greater activation in visual cortex and hippocampus, regions commonly shown to mediate detailed retrieval. More effortful cognitive control regions in the prefrontal and parietal cortices, on the other hand, supported non-schematic recollection, while lateral temporal cortices supported familiarity-based retrieval of non-schematic items. Second, both true and false recollection, as well as familiarity, were mediated by activity in left middle temporal gyrus, a region associated with semantic processing and retrieval of schematic gist. Moreover, activity in this region was greater for both false recollection and false familiarity, suggesting a greater reliance on lateral temporal cortices for retrieval of illusory memories, irrespective of memory strength. Consistent with previous false memory studies, visual cortex showed increased activity for true compared to false recollection, suggesting that visual cortices are critical for distinguishing between previously viewed targets and related lures at retrieval. Additionally, the absence of common visual activity between true and false retrieval suggests that, unlike previous studies utilizing visual stimuli, when false memories are predicated on schematic gist and not perceptual overlap, there is little reliance on visual processes during false memory retrieval. Finally, the medial temporal lobe exhibited an interesting dissociation, showing greater activity for true compared to false recollection, as well as for false compared to true familiarity. These results provided an indication as to how different types of items are retrieved when studied within a highly schematic context. Results both replicate and extend previous true and false memory findings, supporting the Fuzzy Trace Theory. PMID- 27697594 TI - Drug repurposing for glioblastoma based on molecular subtypes. AB - A recent multi-platform analysis by The Cancer Genome Atlas identified four distinct molecular subtypes for glioblastoma (GBM) and demonstrated that the subtypes correlate with clinical phenotypes and treatment responses. In this study, we developed a computational drug repurposing approach to predict GBM drugs based on the molecular subtypes. Our approach leverages the genomic signature for each GBM subtype, and integrates the human cancer genomics with mouse phenotype data to identify the opportunity of reusing the FDA-approved agents to treat specific GBM subtypes. Specifically, we first constructed the phenotype profile for each GBM subtype using their genomic signatures. For each approved drug, we also constructed a phenotype profile using the drug target genes. Then we developed an algorithm to match and prioritize drugs based on their phenotypic similarities to the GBM subtypes. Our approach is highly generalizable for other disorders if provided with a list of disorder-specific genes. We first evaluated the approach in predicting drugs for the whole GBM. For a combined set of approved, potential and off-label GBM drugs, we achieved a median rank of 9.3%, which is significantly higher (p45mmHg to define hypo- and hypercarbia, normocarbia was associated with increased hospital survival (odds ratio [OR] 1.30, 95% confidence interval [CI] 1.23, 1.38). Normocarbia was also associated with a good neurological outcome (cerebral performance category score 1 or 2) compared to hypercarbia (OR 1.69, 95% CI 1.13, 2.51) when the analysis also included an additional study with a slightly different definition for normocarbia (PaCO2 30-50mmHg). CONCLUSIONS: From the limited data it appears PaCO2 has an important U-shape association with survival and outcomes after CA, consistent with international resuscitation guidelines' recommendation that normocarbia be targeted during post-resuscitation care. PMID- 27697607 TI - Enhanced removal of lead from contaminated soil by polyol-based deep eutectic solvents and saponin. AB - Deep eutectic solvents (DESs) are a class of green solvents analogous to ionic liquids, but less costly and easier to prepare. The objective of this study is to remove lead (Pb) from a contaminated soil by using polyol based DESs mixed with a natural surfactant saponin for the first time. The DESs used in this study were prepared by mixing a quaternary ammonium salt choline chloride with polyols e.g. glycerol and ethylene glycol. A natural surfactant saponin obtained from soapnut fruit pericarp, was mixed with DESs to boost their efficiency. The DESs on their own did not perform satisfactory due to higher pH; however, they improved the performance of soapnut by up to 100%. Pb removal from contaminated soil using mixture of 40% DES-Gly and 1% saponin and mixture of 10% DES-Gly and 2% saponin were above 72% XRD and SEM studies did not detect any major corrosion in the soil texture. The environmental friendliness of both DESs and saponin and their affordable costs merit thorough investigation of their potential as soil washing agents. PMID- 27697608 TI - Insight into the role of TSLP in inflammatory bowel diseases. AB - Proinflammatory cytokines are thought to modulate pathogeneses of various inflammatory bowel diseases (IBDs). Thymic stromal lymphopoietin (TSLP), which has been studied in various allergic diseases such as asthma, atopic dermatitis (AD) and eosinophilic esophagitis (EoE), has been less considered to be involved in IBDs. However, mucosal dendritic cells (DCs) induced by various cytokines including TSLP were reported to cause polarization of T cell toward Th2 response, the differentiation of regulatory T-cell (Treg), and secretion of IgA by B cells. In this review, we discuss the concept that decreased TSLP has the potential to accelerate the development of Th1 response dominant diseases such as the Crohn's disease (CD) while increased TSLP has the potential to lead to a development of Th2 cell dominant diseases such the ulcerative colitis (UC). To examine TSLP's role as a potential determining factor for differentiating UC and CD, we analyzed the effects of other genes regulated by TSLP in regards to the UC and CD pathogeneses using data from online open access resources such as NetPath, GeneMania, and the String database. Our findings indicate that TSLP is a key mediator in the pathogenesis of IBDs and that further studies are needed to evaluate its role. PMID- 27697609 TI - Characterization of genetic sequence variation of 58 STR loci in four major population groups. AB - Massively parallel sequencing (MPS) can identify sequence variation within short tandem repeat (STR) alleles as well as their nominal allele lengths that traditionally have been obtained by capillary electrophoresis. Using the MiSeq FGx Forensic Genomics System (Illumina), STRait Razor, and in-house excel workbooks, genetic variation was characterized within STR repeat and flanking regions of 27 autosomal, 7 X-chromosome and 24 Y-chromosome STR markers in 777 unrelated individuals from four population groups. Seven hundred and forty six autosomal, 227 X-chromosome, and 324 Y-chromosome STR alleles were identified by sequence compared with 357 autosomal, 107 X-chromosome, and 189 Y-chromosome STR alleles that were identified by length. Within the observed sequence variation, 227 autosomal, 156 X-chromosome, and 112 Y-chromosome novel alleles were identified and described. One hundred and seventy six autosomal, 123 X chromosome, and 93 Y-chromosome sequence variants resided within STR repeat regions, and 86 autosomal, 39 X-chromosome, and 20 Y-chromosome variants were located in STR flanking regions. Three markers, D18S51, DXS10135, and DYS385a-b had 1, 4, and 1 alleles, respectively, which contained both a novel repeat region variant and a flanking sequence variant in the same nucleotide sequence. There were 50 markers that demonstrated a relative increase in diversity with the variant sequence alleles compared with those of traditional nominal length alleles. These population data illustrate the genetic variation that exists in the commonly used STR markers in the selected population samples and provide allele frequencies for statistical calculations related to STR profiling with MPS data. PMID- 27697610 TI - Repression of Mcl-1 and disruption of the Mcl-1/Bak interaction in myeloma cells couple ER stress to mitochondrial apoptosis. AB - As myeloma cells actively produce and secrete immunoglobulins, they are prone to ER stress, which if unresolved leads to apoptosis. We found that myeloma cell death induced by the ER stressor Thapsigargin was highly variable, ranging from 2 to 89%. Induction of ATF4 and CHOP was observed in myeloma cells under Thapsigargin independently of cell death. The decrease in Mcl-1 was associated with protein translation inhibition and identified as a crucial factor in Thapsigargin sensitivity, since it was the only Bcl-2 family protein differentially modified between sensitive and resistant myeloma cells. Bak but not Bax was found to contribute to Thapsigargin-induced apoptosis. Appropriately, a basal Mcl-1/Bak interaction was demonstrated in Thapsigargin-sensitive cells. Of note, the only pro-apoptotic protein freed from Mcl-1 under Thapsigargin was Bak, whereas Mcl-1/Noxa or Mcl-1/Bim complexes were simultaneously increased. Thus, the disruption of the basal Mcl-1/Bak complex in Thapsigargin-sensitive cells seemed to be an essential event in cell death induction, probably favored by the induced Noxa and Bim BH3-only proteins. These findings underscore the implication of the Mcl-1/Bak axis in myeloma cell death triggered by Thapsigargin. PMID- 27697611 TI - SEI1 induces genomic instability by inhibiting DNA damage response in ovarian cancer. AB - Previous studies have shown that the oncogene SEI1 is highly expressed in ovarian carcinomas, and promoting genomic instability. However, the molecular mechanism of SEI1 in promoting genomic instability remains unclear. We observed SEI1 overexpression in 30 of 46 cases of ovarian cancer compared to non-tumor tissues and the overexpression of SEI1 was positively associated with the tumor FIGO stage. Our functional studies revealed that overexpression of SEI1 could induce genomic instability and increased DNA strand breaks. In contrast, SEI1 co localized with gammaH2AX and phosphorylated ATM and DNAPKcs in the nucleus. Furthermore, we found that overexpression of SEI1 induced translocation of the SEI1 protein from the cytoplasm to the nucleus; ATM and DNAPKcs were associated with the cytoplasm-to-nucleus translocation of SEI1. To further prove the correlation between the DNA damage response (DDR) and SEI1, we knocked down SEI1 expression in SEI1-transfected ovarian cancer cell lines. The expression of DDR proteins was significantly downregulated, and the number of micronuclei was significantly decreased. Together, these results define a new mechanism of SEI1 in the regulation of genomic stability and in the malignant progression of ovarian cancer. PMID- 27697612 TI - Exploring sex differences in the adult zebra finch brain: In vivo diffusion tensor imaging and ex vivo super-resolution track density imaging. AB - Zebra finches are an excellent model to study the process of vocal learning, a complex socially-learned tool of communication that forms the basis of spoken human language. So far, structural investigation of the zebra finch brain has been performed ex vivo using invasive methods such as histology. These methods are highly specific, however, they strongly interfere with performing whole-brain analyses and exclude longitudinal studies aimed at establishing causal correlations between neuroplastic events and specific behavioral performances. Therefore, the aim of the current study was to implement an in vivo Diffusion Tensor Imaging (DTI) protocol sensitive enough to detect structural sex differences in the adult zebra finch brain. Voxel-wise comparison of male and female DTI parameter maps shows clear differences in several components of the song control system (i.e. Area X surroundings, the high vocal center (HVC) and the lateral magnocellular nucleus of the anterior nidopallium (LMAN)), which corroborate previous findings and are in line with the clear behavioral difference as only males sing. Furthermore, to obtain additional insights into the 3-dimensional organization of the zebra finch brain and clarify findings obtained by the in vivo study, ex vivo DTI data of the male and female brain were acquired as well, using a recently established super-resolution reconstruction (SRR) imaging strategy. Interestingly, the SRR-DTI approach led to a marked reduction in acquisition time without interfering with the (spatial and angular) resolution and SNR which enabled to acquire a data set characterized by a 78MUm isotropic resolution including 90 diffusion gradient directions within 44h of scanning time. Based on the reconstructed SRR-DTI maps, whole brain probabilistic Track Density Imaging (TDI) was performed for the purpose of super resolved track density imaging, further pushing the resolution up to 40MUm isotropic. The DTI and TDI maps realized atlas-quality anatomical maps that enable a clear delineation of most components of the song control and auditory systems. In conclusion, this study paves the way for longitudinal in vivo and high-resolution ex vivo experiments aimed at disentangling neuroplastic events that characterize the critical period for vocal learning in zebra finch ontogeny.

AB - OBJECTIVE: To explore women's experiences with giving birth before arrival. DESIGN: A qualitative interview study. SETTING: Individual semi structured interviews with women from Western Norway conducted in their homes in 2015. PARTICIPANTS: 10 women who experienced BBA-births in 2014, or the beginning of 2015. Two primiparous and eight multiparous women participated in the study. KEY FINDINGS: Three themes were generated from the analysis. In the encounter with the healthcare services, the women described midwives as gatekeepers defining active labour. Giving birth before arrival was dramatic, but at some point fear of giving birth alone was replaced by feelings of coping, and in hindsight they felt empowered. The women described giving birth before arrival to be a special experience, but this was not always acknowledged by the midwives. CONCLUSION AND IMPLICATIONS FOR PRACTICE: The findings in this study question the cost-benefit of today's maternity care system pointing towards a more differentiated and decentralised care. To enhance patient safety adequate capacity of midwives in the maternity care is essential. Furthermore, good communication skills are key to improving practice and enhancing safety. Further research must be conducted. PMID- 27697615 TI - Integrative transcriptomic analysis of NAFLD animal model reveals dysregulated genes and pathways in metabolism. AB - Dysregulation of metabolism in hepatocytes leads to hepatic diseases such as hepatitis and non-alcoholic fatty liver disease (NAFLD). NAFLD represents a spectrum of liver diseases ranging from simple steatosis to nonalcoholic steatohepatitis (NASH). NASH is likely to progress to cirrhosis, liver failure and hepatocellular carcinoma, which lead to poor long-term prognosis. However, the exact mechanism of development of NAFLD is not well elucidated. In order to better understand the pathogenesis of NAFLD, we have performed an integrative analysis to livers from NAFLD rat models in a global view of the transcriptome. By systemic and integrative analyses, we have found that transport, angiogenesis and cell adhesion were upregulated in response to high fat diet feeding, which may cause a large amount of free fatty acid transport, hepatic fibrosis and hepatocytes injury. GO tree analysis has shown that angiogenesis was upregulated. GO term in response to high fat diet which may cause fibrosis. The pathway interaction network has indicated that upregulated "valine, leucine, and isoleucine metabolism" may decrease the serum concentration of branched-chain amino acid (BCAA). The enhanced degradation of BCAA in NAFLD animal models may lead to inhibition of the regeneration of hepatocytes, reducing the production of albumin, attenuating the inhibition of liver cancer and decreasing immunity. Overall, high fat diet upregulated a variety of metabolism which have converged at TCA cycle. High fatty has pushed the hepatic mitochondria to a "busy state". Comprehensively, genes participated in dysregulated biological process and metabolisms may be served as indicators for evaluation of NAFLD progression and therapeutic targets. PMID- 27697616 TI - Lipid metabolism in Rhodnius prolixus: Lessons from the genome. AB - The kissing bug Rhodnius prolixus is both an important vector of Chagas' disease and an interesting model for investigation into the field of physiology, including lipid metabolism. The publication of this insect genome will bring a huge amount of new molecular biology data to be used in future experiments. Although this work represents a promising scenario, a preliminary analysis of the sequence data is necessary to identify and annotate the genes involved in lipid metabolism. Here, we used bioinformatics tools and gene expression analysis to explore genes from different genes families and pathways, including genes for fat breakdown, as lipases and phospholipases, and enzymes from beta-oxidation, fatty acid metabolism, and acyl-CoA and glycerolipid synthesis. The R. prolixus genome encodes 31 putative lipase genes, including 21 neutral lipases and 5 acid lipases. The expression profiles of some of these genes were analyzed. We were able to identify nine phospholipase A2 genes. A variety of gene families that participate in fatty acid synthesis and modification were studied, including fatty acid synthase, elongase, desaturase and reductase. Concerning the synthesis of glycerolipids, we found a second isoform of glycerol-3-phosphate acyltransferase that was ubiquitously expressed throughout the organs. Finally, all genes involved in fatty acid beta-oxidation were identified, but not a long chain acyl-CoA dehydrogenase. These results provide fundamental data to be used in future research on insect lipid metabolism and its possible relevance to Chagas' disease transmission. PMID- 27697617 TI - Alcohol-associated cancer and deregulation of Pol III genes. AB - Emerging evidence indicates that alcohol intake is associated with human cancers in different organs. However, the molecular mechanism of alcohol-associated human cancers remains to be elucidated. Here, this paper aimed to clarify a novel mechanism of alcohol-promoted cell transformation and tumor development. Alcohol induces JNK1 activation and increases cellular levels of c-Jun to upregulate Brf1 expression and Pol III gene transcription, leading to an enhancement of rates of cell transformation and tumor formation. PMID- 27697618 TI - Au-Ag core-shell nanoparticles for simultaneous bacterial imaging and synergistic antibacterial activity. AB - Au@Ag nanoparticles (NPs) were recently found to display giant two-photon photoluminescence (2PPL) enhancement, with an enhancement factor up to 815 fold upon aggregate formation. Based on this finding, two-photon imaging of bacteria by Au@Ag NPs under near-infrared (NIR) femtosecond laser pulses was demonstrated in this study, as positively charged Au@Ag NPs can form aggregates on the negatively charged bacterial surface, yielding strong 2PPL emission. The aggregation-enhanced 2PPL of Au@Ag NPs stemmed from higher two-photon excitation efficiency, implying strong two-photon photothermal effects. Au@Ag NPs showed strong antibacterial activity (minimum inhibition concentration as low as 7.5pM against Staphylococcus aureus) and negligible toxicity to human dermal fibroblasts. Their bactericidal activity was further enhanced under NIR irradiation due to strong two-photon photothermal effects. Au@Ag NPs effectively removed 85% of the notorious bacterial biofilm within 4 min under NIR irradiation. These Au@Ag NPs can potentially be used as imaging and antibacterial agents. PMID- 27697619 TI - Stratum corneum targeting by dendritic core-multishell-nanocarriers in a mouse model of psoriasis. AB - Inflammatory disorders of the skin pose particular therapeutic challenges due to complex structural and functional alterations of the skin barrier. Penetration of several anti-inflammatory drugs is particularly problematic in psoriasis, a common dermatitis condition with epidermal hyperplasia and hyperkeratosis. Here, we tested in vivo dermal penetration and biological effects of dendritic core multishell-nanocarriers (CMS) in a murine skin model of psoriasis and compared it to healthy skin. In both groups, CMS exclusively localized to the stratum corneum of the epidermis with only very sporadic uptake by Langerhans cells. Furthermore, penetration into the viable epidermis of nile red as a model for lipophilic compounds was enhanced by CMS. CMS proved fully biocompatible in several in vitro assays and on normal and psoriatic mouse skin. The observations support the concept of CMS as promising candidates for drug delivery in inflammatory hyperkeratotic skin disorders in vivo. PMID- 27697620 TI - Preoperative ultrasound staging of the axilla make's peroperative examination of the sentinel node redundant in breast cancer: saving tissue, time and money. AB - OBJECTIVE: To evaluate the role of preoperative axillary staging with ultrasound (US) and fine needle aspiration cytology (FNAC). Can we avoid intraoperative sentinel lymph node (SLN) examination, with an acceptable revision rate by preoperative staging? DESIGN: This study is based on the retrospective data of 336 patients that underwent US evaluation of the axilla as part of their staging. A FNAC biopsy was performed when abnormal lymph nodes were visualized. Patients with normal appearing nodes on US or a benign diagnostic biopsy had removal of the SLNs without intraoperative pathological examination. We calculated the sensitivity, specificity and accuracy of US/FNAC in predicting the necessity of an axillary lymphadenectomy. Subsequently we looked at the total cost and the operating time of 3 models. Model A is our study protocol. Model B is a theoretical protocol based on the findings of the Z0011 trial with only clinical preoperative staging and in Model C preoperative staging and intraoperative pathological examination were both theoretically done. sentinel node, staging, ultrasound, preoperative axillary staging, FNAC, axilla RESULTS: The sensitivity, specificity and accuracy are respectively 0.75 (0.66-0.82), 1.00 (0.99-1.00) and 0.92 (0.88-0.94). Only 26 out of 317 (8.2%) patients that successfully underwent staging needed a revision. The total cost of Model A was 1.58% cheaper than Model C and resulted in a decrease in operation time by 9,46%. The benefits compared with Model B were much smaller. CONCLUSION: Preoperative US/FNAC staging of the axillary lymph nodes can avoid intraoperative examination of the sentinel node with an acceptable revision rate. It saves tissue, reduces operating time and decreases healthcare costs in general. PMID- 27697621 TI - The effects of uterine artery embolization on ovarian reserve. AB - OBJECTIVE: To evaluate the effects of UAE for symptomatic uterine fibroids on ovarian reserve based on AMH. STUDY DESIGN: This was a retrospective study conducted between March 2011 and October 2014. All women underwent UAE. At baseline and at the 3-month and 12-month follow-up visits, serum anti-Mullerian hormone (AMH), follicle stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels were assessed, and ovarian volume and antral follicle count (AFC) were evaluated in each patient. RESULTS: There were no statistically significant differences in serum E2, LH, or FSH levels or in ovarian volume 3 or 12 months after UAE (P=0.8194, P=0.3976, P=0.4766, and P=0.6822, respectively). However, AMH and AFC were significantly different 3 and 12 months after the procedure (P=0.00, P=0.029 and P=0.00, P=0.00, respectively). AMH levels remained low after 12 months of follow-up compared to the expected AMH levels. A statistically significant recovery of serum AMH at 12 months compared to at 3 months in those <40 years of age (P=0.00), but not in those >=40 years (P=0.837). CONCLUSIONS: Ovarian reserve appears to be affected by UAE in premenopausal women. However, younger ovaries (according to biological ovarian age) exhibit a greater capacity for recovery after ovarian damage. Therefore, larger studies are needed for more conclusive results. PMID- 27697622 TI - Labor market consequences of childhood onset type 1 diabetes. AB - This paper examines the effect of the onset of Type 1 Diabetes Mellitus (T1DM) before 15 years of age on labor market outcomes and contributes to the literature on effects of childhood health on adult socioeconomic status. Using national Swedish socioeconomic register data 1991-2010 for 2485 individuals born 1972-1978 with onset of T1DM in 1977-1993, we find that T1DM in childhood has a negative effect on labor market outcomes later in life. Part of the T1DM effect is channeled through occupational field which may be related to both choice and opportunities. Although the magnitude of the effect is only directly generalizable to illnesses with similar attributes as T1DM, the results suggest that causality in the often observed correlation between health and socioeconomic status, at least partly, is explained by an effect running from health to earnings. This has implications for research and policy on strategies to reduce socioeconomic-related health inequality. Our findings also shed light on productivity losses, measured by employment status and earnings due to childhood onset T1DM, which have implications for both the individual and society.

PMID- 27697626 TI - High nasal resistance is stable over time but poorly perceived in people with tetraplegia and obstructive sleep apnoea. AB - Obstructive sleep apnoea (OSA) is highly prevalent in people with tetraplegia. Nasal congestion, a risk factor for OSA, is common in people with tetraplegia. The purpose of this study was to quantify objective and perceived nasal resistance and its stability over four separate days in people with tetraplegia and OSA (n=8) compared to able-bodied controls (n=6). Awake nasal resistance was quantified using gold standard choanal pressure recordings (days 1 and 4) and anterior rhinomanometry (all visits). Nasal resistance (choanal pressure) was higher in people with tetraplegia versus controls (5.3[6.5] vs. 2.1[2.4] cmH2O/L/s, p=0.02) yet perceived nasal congestion (modified Borg score) was similar (0.5[1.8] vs. 0.5[2.0], p=0.8). Nasal resistance was stable over time in both groups (CV=0.23+/-0.09 vs. 0.16+/-0.08, p=0.2). These findings are consistent with autonomic dysfunction in tetraplegia and adaptation of perception to high nasal resistance. Nasal resistance may be an important therapeutic target for OSA in this population but self-assessment cannot reliably identify those most at risk. PMID- 27697627 TI - Body weight unloading modifications on frontal plane joint moments, impulses and Center of Pressure during overground gait. AB - BACKGROUND: Body weight unloading is a common method of gait rehabilitation. However, little is known about its effects on the overground gait biomechanical parameters which were often confounded by the walking modality (treadmill) or the speed variability when subjects walked overground while having to pull the body weight unloading system to which they were attached. By designing a mechanical device that pulled the system at a constant speed, we were able to assess the unique effects of body weight unloading on healthy subjects' kinetics during overground gait. METHODS: Fifteen healthy subjects walked overground under three (0%, 15%, and 30%) body weight unloading experimental conditions. Kinetic measures included hip and knee frontal plane moments and impulses and the foot center of pressure. FINDINGS: A significant inverse relationship was shown between increased body weight unloading levels (0% to 30%) and a decrease in the hip and knee first adduction moments and impulses and an increase in the lateral shift of the foot center of pressure. Frontal plane hip and knee kinetic curvature patterns remained similar as evidenced by low normalized RMSE under paired comparisons of the experimental conditions. INTERPRETATION: Overground gait with up to 30% body weight unloading stands out as an efficient method of reducing loads on joints without distorting kinetic gait curvature patterns. The relationship between increased unloading with decreased hip and knee moments and impulses and increased lateral shift of the center of pressure also suggests that this shift may be an important diagnostic tool in gait assessment and correction. PMID- 27697628 TI - Coxsackievirus B heart infections and their putative contribution to sudden unexpected death: An 8-year review of patients and victims in the coastal region of Tunisia. AB - Coxsackieviruses B (CV B) are known as the most common viral cause of human heart infections. Cardiac inflammations contribute to sudden unexpected death (SUD) significantly. The diagnosis remains difficult with the traditional diagnostic tests and must be substantially improved. This has prompted health professionals to seek new diagnostic procedures which may provide important clues regarding underlying etiology. The present study is based on patients with infectious heart diseases and SUD victims with no relevant pathologies. They were investigated for possible CV-B infection. Patients with coronary artery diseases and unnatural road and domestic accident victims served as controls. The samples were studied for CV-B applying PCR. Histopathology for inflammatory markers, immunohistochemistry (IHC) for immune inflammatory cells and the enteroviral VP1 capsid protein were performed. Overall, 102 patients and 87 SUD victims were studied. As controls, 100 patients and 54 SUD unnatural accident victims were enrolled. CV-B were detected in 28 patients and 15 SUD victims. The control group samples were completely virus negative. Compared to controls, IHC revealed a significant presence of T and B lymphocytes within the myocardium. Furthermore, enteroviral VP1-capsid protein were detected from samples by IHC. Applying a comprehensive combination of methods, our results demonstrate the involvement of CV-B in cases of heart infection suggesting they play a significant role in SUD. Our results emphasize the importance of opting for a combination of methods. PMID- 27697629 TI - Age estimation of Calliphora (Diptera: Calliphoridae) larvae using cuticular hydrocarbon analysis and Artificial Neural Networks. AB - Cuticular hydrocarbons were extracted daily from the larvae of two closely related blowflies Calliphora vicina and Calliphora vomitoria (Diptera: Calliphoridae). The hydrocarbons were then analysed using Gas Chromatography-Mass Spectrometry (GC-MS), with the aim of observing changes within their chemical profiles in order to determine the larval age. The hydrocarbons were examined daily for each species from 1day old larvae until pupariation. The results show significant chemical changes occurring from the younger larvae to the post feeding larvae. With the aid of a multivariate statistical method (Principal Component Analysis and Artificial Neural Networks), samples were clustered and classified, allowing for the larval age to be established. Results from this study allowed larvae to be aged to the day with at worst, 87% accuracy, which suggests there is great potential for the use of cuticular hydrocarbons present on larvae to give an indication of their age and hence potentially a valuable tool for minimum PMI estimations. PMID- 27697630 TI - AIC and the challenge of complexity: A case study from ecology. AB - Philosophers and scientists alike have suggested Akaike's Information Criterion (AIC), and other similar model selection methods, show predictive accuracy justifies a preference for simplicity in model selection. This epistemic justification of simplicity is limited by an assumption of AIC which requires that the same probability distribution must generate the data used to fit the model and the data about which predictions are made. This limitation has been previously noted but appears to often go unnoticed by philosophers and scientists and has not been analyzed in relation to complexity. If predictions are about future observations, we argue that this assumption is unlikely to hold for models of complex phenomena. That in turn creates a practical limitation for simplicity's AIC-based justification because scientists modeling such phenomena are often interested in predicting the future. We support our argument with an ecological case study concerning the reintroduction of wolves into Yellowstone National Park, U.S.A. We suggest that AIC might still lend epistemic support for simplicity by leading to better explanations of complex phenomena. PMID- 27697631 TI - Buccal absorption of diazepam is improved when administered in bioadhesive tablets-An in vivo study in conscious Gottingen mini-pigs. AB - Buccal delivery may be clinically beneficial for compounds with a high gastrointestinal and hepatic first pass metabolism or in situations where a fast systemic absorption is desired. The delivery of a crystalline low soluble compounds, e.g. diazepam, may be limited due to the low volume of saliva available to facilitate solvation in order to drive the permeation of drug through the buccal mucosa. Therefore, the present study investigated the potential benefits of administering diazepam either as an amorphous or as a crystalline form in mucoadhesive tablets to conscious Gottingen mini-pigs. Presentation of the compound in the amorphous form lead to a very fast absorption, however, the obtained bioavailability was at the same level observed following buccal administration of a commercially immediate release tablet. Addition of chitosan, as a mucoadhesive excipient, resulted in a higher absolute bioavailability compared to tablets without chitosan. The absorption rate for the chitosan-based tablets was significant slower, probably due to the slower diffusion of the compound out of the tablet. In vitro release data was able to predict the variations in tmax, but otherwise no correlation could be found between in vitro and in vivo data. PMID- 27697633 TI - Targeted release of transcription factors for cell reprogramming by a natural micro-syringe. AB - Ectopic expression of defined transcription factors (TFs) for cell fate handling has proven high potential interest in reprogramming differentiated cells, in particular for regenerative medicine, ontogenesis study and cell based modelling. Pluripotency or transdifferentiation induction as TF mediated differentiation is commonly produced by transfer of genetic information with safety concerns. The direct delivery of proteins could represent a safer alternative but still needs significant advances to be efficient. We have successfully developed the direct delivery of proteins by an attenuated bacterium with a type 3 secretion system that does not require challenging and laborious steps for production and purification of recombinant molecules. Here we show that this natural micro syringe is able to inject TFs to primary human fibroblasts and cord blood CD34+ hematopoietic stem cells. The signal sequence for vectorization of the TF Oct4 has no effect on DNA binding to its nucleic target. As soon as one hour after injection, vectorized TFs are detectable in the nucleus. The injection process is not associated with toxicity and the bacteria can be completely removed from cell cultures. A three days targeted release of Oct4 or Sox2 embryonic TFs results in the induction of the core pluripotency genes expression in fibroblasts and CD34+ hematopoietic stem cells. This micro-syringe vectorization represents a new strategy for TF delivery and has potential applications for cell fate reprogramming. PMID- 27697632 TI - Improving adjuvanticity of quaternized chitosan-based microgels for H5N1 split vaccine by tailoring the particle properties to achieve antigen dose sparing effect. AB - In this study, we developed the quaternized chitosan microgels without chemical crosslinking as an adjuvant of H5N1 split vaccine. The microgels with pH sensitivity, positive surface charge and good biocompatibility, have been demonstrated in favor of enhancing both humoral and cellular immune response. However, the detailed mechanism of the chitosan-based microgels to enhance antigen specific immune responses remains unclear. Therefore, we prepared the quaternized chitosan microgels with well defined quaternization degrees (QDs, 20 80%) and particle sizes (800nm-5MUm) by the premix membrane emulsification technique, and investigated the effect of quaternization degree (QD) and size on the adjuvanticity of microgels. Results suggested that microgels with relatively smaller size (807nm) and moderate quaternization degree (QD 41% and 60%) were favorable for a maximum immune response. The mechanism was studied and explained by examining the characteristics of microgels and investigating the stimulation of bone-marrow derived dendritic cells (BMDCs). Moreover, they induced significantly stronger immune responses at lower antigen doses (known as antigen sparing effect) compared to aluminum adjuvant. These data indicated that a maximum immune response can be achieved by controlling properties of chitosan microgels, which also could serve as a significant guidance for rational design of chitosan-based particle adjuvant. PMID- 27697634 TI - Accumulation of persistent organic pollutants in consumers of eel from polluted rivers compared to marketable eel. AB - Globally, many river sediments are seriously contaminated with persistent organic pollutants (POPs) known to accumulate in aquatic food. In the Netherlands, toxicological risks of human exposure to dioxins and dioxin-like compounds led to a ban on eel fishing in the Rhine-Meuse delta. The aim of this study is to investigate differences in serum POP levels in consumers of eel from high polluted areas and consumers of eel from low-polluted areas or aquaculture. In total 80 Dutch men were included, aged 40-70 years, with a habitual eel consumption of at least one portion (150 g) per month. Total levels of dioxins and dioxin-like compounds were measured in serum of all participants with the DR CALUX bioassay, validated with GC-MS. For a subgroup of 38 participants extensive POP measurements were performed. We revealed that consumption of eel from polluted rivers resulted in 2.5 and up to 10 times increased levels of dioxins and polychlorinated biphenyls (PCBs) respectively compared to controls. The highest PCB levels were detected for PCB 153, with a median level of 896 ng/g lipid and a maximum level of 5000 ng/g lipid in the high-exposed group. Furthermore, hydroxylated PCB metabolites (OH-PCBs: sum of 4-OH-CB107, 4-OH CB146, 4'-OH-CB172, and 4-OH-CB187) were 8 times higher in men who consumed eel from polluted areas, and detected at levels (median 4.5 ng/g ww) reported to cause adverse health effects. Also, the majority of the perfluoroalkyl substances (PFASs) were significantly higher in consumers of eel from pullulated areas. In conclusion, this study is the first to reveal that (past) consumption of eel from polluted rivers resulted in high body burdens of dioxins, PCBs, OH-PCBs and PFASs. We confirmed the predictions made in a former risk assessment, and the high levels of dioxins and dioxin-like compounds as well as the OH-PCBs are of health concern. PMID- 27697635 TI - Apple pectin: A natural source for cancer suppression in 4T1 breast cancer cells in vitro and express p53 in mouse bearing 4T1 cancer tumors, in vivo. AB - PURPOSE: Increase in the number of cancer related deaths has made the study on developing new drugs and treatments essential. One of the main aims in developing new therapies is to use natural resources which have the ability to induce apoptosis. Pectin is one of these natural compounds, a complex polysaccharide found in apples with anti-cancer properties. The aim of this study was to examine anti-cancer properties of pectic acid both in vitro in 4T1 breast cancer cells and in vivo using an animal model of breast cancer. EXPERIMENTAL DESIGN: MTT cell proliferation assays, double fluorescence staining (acridine orange/ethidium bromide) and cell cycle analysis were employed to measure apoptosis in vitro. 4T1 cells were implanted into female BALB/c mice for in vivo studies. Then tumor volumes, histological analysis and immunohistochemical staining of P53 and tunnel test were applied to evaluate apoptosis in tumors. RESULTS: The results of in vitro studies showed that concentration of 0.1% of pectic acid could induce apoptosis, inhibit cell growth (p<0.001) and reduce cell attachment, fragmented chromatin, and membrane blebbing as well as blocking the sub-G1 phase (p<0.001). In addition, in vivo studies showed that pectic acid could inhibit the progression of tumors through over-expression of P53 and increasing the number of apoptotic cells. CONCLUSION: Our results demonstrated that pectic acid, a natural component of apple, can prevent metastasis in both cancer cell lines and primary tumors. This potential effect is mainly due to its ability to induce apoptosis. PMID- 27697636 TI - Anxa5 mediates the in vitro malignant behaviours of murine hepatocarcinoma Hca-F cells with high lymph node metastasis potential preferentially via ERK2/p-ERK2/c Jun/p-c-Jun(Ser73) and E-cadherin. AB - OBJECTIVE: Annexin A5 (Anxa5) is associated with the progression of some cancers, while its role and regulation mechanism in tumor lymphatic metastasis is rarely reported. This study aims to investigate the influence of Anxa5 knockdown on the malignant behaviours of murine hepatocarcinoma Hca-F cell line with high lymph node metastatic (LNM) potential and the underlying regulation mechanism. METHODS: RNA interfering was performed to silence Anxa5 in Hca-F. Monoclonal shRNA-Anxa5- Hca-F cells were obtained via G418 screening by limited dilution method. Quantitative real-time RT-PCR (qRT-PCR) and Western blotting (WB) were applied to measure Anxa5 expression levels. CCK-8, Boyden transwell-chamber and in situ LN adhesion assays were performed to explore the effects of Anxa5 on the proliferation, migration, invasion and adhesion capacities of Hca-F. WB and qRT PCR were used to detect the level changes of key molecules in corresponding signal pathways. RESULTS: We obtained two monoclonal shRNA-Anxa5-transfected Hca F cell lines with stable knockdowns of Anxa5. Anxa5 knockdown resulted in significantly reduced proliferation, migration, invasion and in situ LN adhesion potentials of Hca-F in proportion to its knockdown extent. Anxa5 downregulation enhanced E-cadherin levels in Hca-F. Moreover, Anxa5 affected Hca-F behaviours specifically via ERK2/p-ERK2/c-Jun/p-c-Jun(Ser73) instead of p38MAPK/c-Jun, Jnk/c Jun and AKT/c-Jun pathways. CONCLUSIONS: Anxa5 mediates the in vitro malignant behaviours of murine hepatocarcinoma Hca-F cells via ERK2/c-Jun/p-c-Jun(Ser73) and ERK2/E-cadherin pathways. It is an important molecule in metastasis (especially LNM) and a potential therapeutic target for hepatocarcinoma. PMID- 27697637 TI - Possible contributions of thyroid hormone replacement to specific behaviors of cancer. AB - l-Thyroxine (T4) is the principal replacement hormone for patients who have hypothyroidism. Some preclinical and clinical evidence supports the possibility that T4 can at least permissively affect certain features of established cancers and cancer-relevant angiogenesis. Thus, in the occasional patient with hypothyroidism and concomitant cancer, it appears reasonable to consider thyroid hormone replacement exclusively with 3,3',5-triiodo-l-thyronine (T3). This use of T3 has been shown to be effective and safe in early experience with medical induction of euthyroid hypothyroxinemia in patients with advanced solid tumors. PMID- 27697638 TI - Suppression of lymphangiogenesis by soluble vascular endothelial growth factor receptor-2 in a mouse lung cancer model. AB - The vascular endothelial growth factor (VEGF) family has a key role in the formation of blood vessels and lymphatics. Among the members of this family, VEGF C is one of the most important factors involved in lymphangiogenesis via binding with two receptors (vascular endothelial growth factor receptor-2 and -3: VEGFR-2 and VEGFR-3). Soluble VEGFR-2 (sVEGFR-2) has a role in maintaining the alymphatic state of the cornea associated with binding to VEGF-C, and selectively inhibits lymphangiogenesis but not angiogenesis. In this study, we introduced sVEGFR-2 into lung cancer cells and evaluated the influence on tumor progression and on genes regulating lymphatic formation and metastasis in vivo. A retroviral vector was used to introduce the sVEGFR-2 gene into Lewis lung carcinoma cells (LLC), which were designated as LLC-sVEGFR-2 cells. Proteins secreted into the culture supernatant by these cells were detected by western blotting using specific antibodies. To examine lymphangiogenesis by primary lung cancer in vivo, LLC sVEGFR-2 cells were subcutaneously injected into C57BL/6 mice. At 14days after injection, immunohistochemistry was performed using an antibody directed against lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1), a marker of lymphatics. Expression of mRNA for VEGFR-2, VEGFR-3 and matrix metalloproteinases (MMPs) was also determined by real-time PCR. Furthermore, LLC-sVEGFR-2 cells were directly inoculated into the left lung in C57BL/6 mice and the number of micro metastases in pulmonary lymph nodes was determined. Introduction of sVEGFR-2 into LLC cells resulted in secretion of sVEGFR-2 protein into the culture supernatant. There were fewer LYVE-1 positive lymphatics after inoculation of LLC-sVEGFR-2 into mice compared with the control group. In addition, VEGFR-2, VEGFR-3, and MMPs gene expression was suppressed in the primary tumors of the LLC-sVEGFR-2 group compared with the control group. Furthermore, there were fewer micro metastases in the pulmonary lymph nodes of the LLC-sVEGFR-2 group compared with the control group after cells were directly inoculated into the lung. These findings indicate that introduction of sVEGFR-2 suppressed lymphangiogenesis in primary lung cancer and also suppressed lymphogenic metastasis by inhibiting VEGF C, followed by down-regulation of VEGFR-2, VEGFR-3 and MMPs. Accordingly, sVEGFR 2 might be a promising target for treatment of cancer by regulating lymphangiogenesis and lymphogenic metastasis. PMID- 27697639 TI - Effect of notch1,2,3 genes silicing on NF-kappaB signaling pathway of macrophages in patients with atherosclerosis. AB - BACKGROUND: Notch and NF-kappaB signaling pathways both play important roles in the regulation of atherosclerosis (AS). However, the mechanisms of notch and NF kappaB signaling pathways on AS are still unclear. In this study, we aimed to investigate the effects of notch1,2,3 genes silicing by siRNA on notch and NF kappaB signaling pathways of macrophages in patients with atherosclerosis (AS), so as to seek the treatment of AS from genetic perspective. METHODS: Peripheral blood mononuclears of 31 patients with AS were isolated by density gradient centrifugation and transformed by PMA to macrophages. Then macrophages were transfected with notch1-siRNA (notch1-siRNA group), notch2-siRNA (notch2-siRNA group), notch3-siRNA (notch3-siRNA group), negative control siRNA (NC group) and none (control group). RT-PCR and Western blot analysis were applied to assess the expression level of Delta-like-4 (DLL4), Jagged-1 (JAG1), IkappaBalpha and P52. Electrophoretic mobility shift assay (EMSA) was used to observe the NF-kappaB DNA binding activity. Subcellular distributions of NF-kappaB/P52 were detected through immunofluorescence. mRNA expression levels of TNF-alpha, IL-6 and IL-6 in macrophages were also determined with RT- PCR. The expression of 20S proteasome was detected by Western blot. RESULTS: After transfected with siRNA, there was no difference in the expression of DLL4, JAG1, IkappaBalpha and P52 between NC group and control group (p>0.05). Compared with NC group and control group, the expression of DLL4, P52 and JAG1 in notch1-siRNA group, notch2-siRNA group and notch3-siRNA group was significantly downregulated (p<0.05 or p<0.01, respectively), whereas the expression of IkappaBalpha was significantly increased (P<0.05 or p<0.01, respectively), especially in notch1-siRNA group. The binding activity of NF-kappaB DNA was lower in notch1- siRNA group, notch2-siRNA group and notch3-siRNA group compared with NC group and control group (p<0.05), especially in notch1-siRNA group. The fluorescence intensity of p52 was decreased significantly both in the nucleus and cytoplasm in notch1-siRNA group, notch2 siRNA group and notch3-siRNA group compared with NC group and control group (p<0.05), which decreased more obviously in the nucleus, especially in notch1 siRNA group. The TNF-alpha, IL-1 and IL-6 expression of notch1-siRNA group, notch2-siRNA group and notch3-siRNA group was lower compared to NC group and control group (p<0.05 or p<0.01, respectively), also especially in notch1-siRNA group. 20S proteasome level was significantly lower in notch1-siRNA group, notch2 siRNA group and notch3-siRNA group than in NC group and control group (p<0.05 or p<0.01, respectively), especially in notch1-siRNA group. CONCLUSIONS: There was a positive regulation between Notch and NF-kappaB signaling pathway in patients with AS. Notch1 may play a more important role than notch2 and notch 3 in the regulation of NF-kappaB signaling pathway in AS.

AB - The aim of the study was to evaluate the association between in utero exposure to drugs that potentially exhibit immunosuppressive activity and occurrence of infections during the first year of life. We conducted a cohort study on the prescription data of pregnant women and their children registered in EFEMERIS cohort (France), during a one-year period. We classified in utero child exposure according to the number of reimbursements for immunosuppressive drugs during pregnancy. The number of infectious episodes during the first year of life was estimated through the number of anti-infective drugs dispensed. The association was estimated by a quasi-Poisson regression with adjustment for confounders. The study population consisted of 9614 children, 3141 of whom had been exposed to immunosuppressive drugs during pregnancy. The most frequently immunosuppressive drugs prescribed were corticosteroids. The mean number of infectious episodes during the first year after birth gradually increased with the number of immunosuppressive drugs dispensed during pregnancy (from 2.38 in controls to 3.88 in the most exposed group). After adjustment for potential confounders, in utero exposure to immunosuppressive drugs was significantly associated with the number of infectious episodes during the first year of life (RR 3ormoreexposuresVS0=1.35, 95% CI 1.24-1.46). Intrauterine exposure to potentially immunosuppressive drugs could be associated with an increased susceptibility to infections in early childhood.

AB - BACKGROUND: Annexin A2, a calcium-dependent phospholipid binding protein, is involved in osteogenesis. The objective of the present study was to explore the expression of Annexin A2 in spinal ligament tissues (LT) of ankylosing spondylitis (AS) patients and determine its pathological functions. METHODS: mRNA and protein expression of Annexin A2 was detected by real-time PCR and Western blotting, respectively. Interleukin-6 (IL-6) concentration in serum was assessed by enzyme linked immunosorbent assay. Alkaline phosphatase (ALP) activity was measured with ALP activity kit on a microplate reader. RESULTS: mRNA and protein expression of Annexin A2 in LT, and IL-6 concentration in serum were significantly increased in AS patients. Moreover, exogenous IL-6 treatment significantly up-regulated Annexin A2 expression and ALP activity. Silencing of Annexin A2 expression significantly ameliorated IL-6-induced ossification of fibroblasts from AS patients, as indicated by ALP activity, expression of proteins associated with osteogenic differentiation, including bone morphogenetic protein-2, osteocalcin and osterix, and the ratio of osteoprotegerin to receptor activator of NF-kappaB ligand. Further MEK inhibitor experiments suggested that Annexin A2 may exert its function through extracellular signal-related kinase pathway. CONCLUSIONS: Annexin A2, up-regulated by IL-6, may promote ligament ossification of AS patients. PMID- 27697642 TI - Forty years later: Mitochondria as therapeutic targets in muscle diseases. AB - The hypothesis that mitochondrial dysfunction can be a general mechanism for cell death in muscle diseases is 40 years old. The key elements of the proposed pathogenetic sequence (cytosolic Ca2+ overload followed by excess mitochondrial Ca2+ uptake, functional and then structural damage of mitochondria, energy shortage, worsened elevation of cytosolic Ca2+ levels, hypercontracture of muscle fibers, cell necrosis) have been confirmed in amazing detail by subsequent work in a variety of models. The explicit implication of the hypothesis was that it "may provide the basis for a more rational treatment for some conditions even before their primary causes are known" (Wrogemann and Pena, 1976, Lancet, 1, 672 674). This prediction is being fulfilled, and the potential of mitochondria as pharmacological targets in muscle diseases may soon become a reality, particularly through inhibition of the mitochondrial permeability transition pore and its regulator cyclophilin D.

AB - Berberine is the principal component of many popular medicinal plants (e.g. the genus Berberis, Coptis and Hydrastis among others) with a history of thousands of years of usage in traditional medicine. The numerous pharmacological activities of berberine reported in the last two decades have been attracting high level interests both within the scientific community, clinicians and the public at large. Despite enormous amount of efforts have been placed to show its therapeutic value for inflammatory bowel diseases (IBD), however, comprehensive up-to-date review article in this field is not yet available. In this communication, literature data from in vitro and in vivo experiments were scrutinised and concisely presented to demonstrate its anti-IBD potential. Beyond the known general antioxidant and anti-inflammatory effects of berberine, IBD specific effects including gut epithelial barrier pathology, T cells as emerging targets, antinociceptive and other effects are discussed. PMID- 27697644 TI - Epigenetic regulation of active Chinese herbal components for cancer prevention and treatment: A follow-up review. AB - Epigenetic modifications include DNA methylation, histone modification, and other patterns. These processes are associated with carcinogenesis and cancer progression. Thus, epigenetic modification-related enzymes, such as DNA methyltransferases (DNMTs), histone methyltransferases (HMTs), histone demethylases (HDMTs), histone acetyltransferases (HATs), and histone deacetylases (HDACs), as well as some related proteins, including methyl-CpG binding proteins (MBPs) and DNMT1-associated protein (DMAP 1), are considered as potential targets for cancer prevention and therapy. Numerous natural compounds, mainly derived from Chinese herbs and chemically ranging from polyphenols and flavonoids to mineral salts, inhibit the growth and development of various cancers by targeting multiple genetic and epigenetic alterations. This review summarizes the epigenetic mechanisms by which active compounds from Chinese herbs exert their anti-cancer effect. A subset of these compounds, such as curcumin and resveratrol, affect multiple epigenetic processes, including DNMT inhibition, HDAC inactivation, MBP suppression, HAT activation, and microRNA modulation. Other compounds also regulate epigenetic modification processes, but the underlying mechanisms and clear targets remain unknown. Accordingly, further studies are required. PMID- 27697645 TI - Dibenzo[b,f][1,4]oxazepines and dibenzo[b,e]oxepines: Influence of the chlorine substitution pattern on the pharmacology at the H1R, H4R, 5-HT2AR and other selected GPCRs. AB - Inspired by VUF6884 (7-Chloro-11-(4-methylpiperazin-1 yl)dibenzo[b,f][1,4]oxazepine), reported as a dual H1/H4 receptor ligand (pKi: 8.11 (human H1R (hH1R)), 7.55 (human H4R (hH4R))), four known and 28 new oxazepine and related oxepine derivatives were synthesised and pharmacologically characterized at histamine receptors and selected aminergic GPCRs. In contrast to the oxazepine series, within the oxepine series, the new compounds showed high affinity to the hH1R (pKi: 6.8-8.7), but no or moderate affinity to the hH4R (pKi:<=5.3). For one oxepine derivative (1-(2-Chloro-6,11 dihydrodibenzo[b,e]oxepin-11-yl)-4-methylpiperazine), the enantiomers were separated and the R-enantiomer was identified as the eutomer at the hH1R (pKi: 8.83 (R), 7.63 (S)) and the guinea-pig H1R (gpH1R) (pKi: 8.82 (R), 7.41 (S)). Molecular dynamic studies suggest that the tricyclic core of the compounds is bound in a similar mode into the binding pocket, as described for doxepine in the hH1R crystal structure. Moreover, docking studies of all oxepine derivatives at the hH1R indicate that the oxygen and the position of the chlorine in the tricyclic core determines, if the R- or the S-enantiomer is the eutomer. For some of the oxazepines and oxepines the affinity to other aminergic GPCRs is in the same range as to hH1R or hH4R, thus, those compounds have to be classified as dirty drugs. However, one oxazepine derivative (3,7-Dichloro-11-(4 methylpiperazin-1-yl)dibenzo[b,f][1,4]oxazepine was identified as dual hH1/h5 HT2A receptor ligand (pKi: 9.23 (hH1R), 8.74 (h5-HT2AR), <=7 at other analysed GPCRs), whereas one oxepine derivative (1-(3,8-Dichloro-6,11 dihydrodibenzo[b,e]oxepin-11-yl)-4-methylpiperazine) was identified as selective hH1R antagonist (pKi: 8.44 (hH1R), <=6.7 at other analyzed GPCRs). Thus, the pharmacological results suggest that the oxazepine/oxepine moiety and additionally the chlorine substitution pattern toggles receptor selectivity and specificity. PMID- 27697646 TI - Efficacy and risk profile of anti-diabetic therapies: Conventional vs traditional drugs-A mechanistic revisit to understand their mode of action. AB - An increasing array of anti-diabetic drugs are available today, yet Type-2 diabetes mellitus (T2DM) - remains a life threatening disease, causing high mortality and morbidity in developing and developed countries. As of now, no effective therapy is available for the complete eradication/cure of diabetes and its associated complications. Therefore, it is time to re-think and revisit molecular pathways and targets of each existing drug in order to identify multiple targets from different signaling pathways that may be manipulated simultaneously to treat or manage T2DM effectively. Bearing this goal in mind, the article reviews the mechanisms of action of available anti-diabetic drugs with in-depth mechanistic analysis of each therapy. The conventional and herbal strategies are analysed and compared for their benefits and the associated possible side effects. This critical information is necessary not only for the development of better, novel and potent anti-diabetic therapy in future but also for best possible combinational therapies and strategies with the available drugs. PMID- 27697647 TI - Prevalence and prevention of cardiovascular disease and diabetes mellitus. AB - Noncommunicable diseases (NCDs) have become important causes of mortality on a global scale. According to the report of World Health Organization (WHO), NCDs killed 38 million people (out of 56 million deaths that occurred worldwide) during 2012. Cardiovascular diseases accounted for most NCD deaths (17.5 million NCD deaths), followed by cancers (8.2 million NCD deaths), respiratory diseases (4.0 million NCD deaths) and diabetes mellitus (1.5 million NCD deaths). Globally, the leading cause of death is cardiovascular diseases; their prevalence is incessantly progressing in both developed and developing nations. Diabetic patients with insulin resistance are even at a greater risk of cardiovascular disease. Obesity, high cholesterol, hypertriglyceridemia and elevated blood pressure are mainly considered as major risk factors for diabetic patients afflicted with cardiovascular disease. The present review sheds light on the global incidence of cardiovascular disease and diabetes mellitus. Additionally, measures to be taken to reduce the global encumbrance of cardiovascular disease and diabetes mellitus are highlighted. PMID- 27697648 TI - Magnetic core-shell hybrid nanoparticles for receptor targeted anti-cancer therapy and magnetic resonance imaging. AB - Hybrid nanoparticles with magnetic poly (lactide-co-glycolide) (PLGA) nanoparticle 'core', surface modified with folate-chitosan (fol-cht) conjugate 'shell' are evaluated as simultaneous anti-cancer therapeutic and MRI contrast agent. The fol-cht conjugate is prepared using carbodiimide crosslinking chemistry at an optimized folate to amine (chitosan) molar ratio for further coating on PLGA nanoparticles loaded with docetaxel and well packed super paramagnetic iron oxide nanoparticles (SPIONs). Apart from possessing a targeting moiety, the coating provides a physical barrier to avoid undesired burst release of drug and also imparts sensitivity to acidic pH, due to protonated amine group dependent decondensation of the coating and subsequent drug release. The biocompatible hybrid nanoparticles provide receptor targeted docetaxel and SPION delivery for anti-cancer therapy and magnetic resonance (MR) imaging respectively, as tested in both folate receptor positive and negative cancer cells. Enhancement in nanoparticle uptake by folate receptor positive oral cancer cells caused significant increase in docetaxel mediated cytotoxicity. While polymeric encapsulation and fol-cht coating negatively affects the magnetic property of iron oxide nanoparticles, their aggregation in the core, shortened the overall T2 relaxation time thereby enhancing the nanoparticle relaxivity to provide better in vitro MR imaging. PMID- 27697649 TI - Enhancing the upconversion luminescence and photothermal conversion properties of ~800nm excitable core/shell nanoparticles by dye molecule sensitization. AB - Upconversion nanoparticles capable of strongly absorbing photons in a wide spectral range are highly desired for practical applications. In this work, IR 806 dye was used to increase the light absorptivity of Nd3+/Yb3+/Er3+ tri-doped core/shell nanoparticles and then to enhance their upconversion luminescence under ~800nm excitation. The IR-806 dye exhibited more efficient energy transfer to Nd3+ ions than to Yb3+ ions for subsequent upconversion emission due to the increased spectral overlap between the dye emission and Nd3+ absorption. The influence of the Nd3+ concentration in the shell and the dye/nanoparticle ratio on the dye-sensitization effect was also investigated. A maximum 28-fold overall enhancement in the emission intensity was achieved for NaYF4:Yb3+/Er3+@NaYF4:Yb3+/Nd3+ core/shell nanoparticles using dye sensitization. The dye-sensitized NaYF4:Yb3+/Er3+@NaYF4:Yb3+/Nd3+ core/shell nanoparticles also exhibited increased photothermal conversion capabilities and excellent temperature sensing properties, enabling their potential application in photothermal nanoheaters with real-time temperature monitoring under 808nm single beam excitation.

AB - Magnetic core-shell ZnFe2O4/ZnS composites were synthesized through a two-step chemical process including the hydrothermal and the co-precipitation methods. The structural characterization revealed that the composites consisted of a layer of ZnS clusters on the surface of ZnFe2O4 nanoparticles. The band gap energy of the composite was estimated to be 2.2eV through the Kubelka-Munk plot, implying the possible application as a photocatalyst under the visible light radiation. The improved photocatalytic efficiency of the ZnFe2O4/ZnS composites was confirmed through the photocatalytic degradation of Methyl Orange. The increased absorption of the visible light and the enhanced separation of the electron-hole pairs due to the relative energy band positions in ZnFe2O4 and ZnS are considered as the main advantages. Additionally, the moderate magnetization of the ZnFe2O4 core insured the easy magnetic collection of the composite materials without affecting the photocatalytic performance. Our results showed that ZnFe2O4-based nanocomposites could be used as an effective and magnetic retrievable photocatalyst. PMID- 27697650 TI - Functionalization of mixed ligand metal-organic frameworks as the transport vehicles for drugs. AB - We reported the design and synthesis of mixed ligands Cu-metal organic frameworks (MOFs), MOFs-2 and MOFs-3, and their application as the transport vehicles for the delivery of Ibuprofen (IBU) and doxorubicin hydrochloride (DOX). The unique MOFs with mixed ligands, 1,3,5-benzene tricarboxylate (BTC) and isophthalic acid (IPA), were easily prepared by hydro-thermal method, and their structures were well characterized by XRD, FTIR, and SEM imaging analysis. Single ligand MOFs with BTC or IPA only were also prepared and characterized as the control group. The biocompatibility of synthesized MOFs towards human cells, HEK 293A was evaluated by MTT assay. To demonstrate the practical applications of the prepared MOFs as the transport vehicles for drugs, the capability of loading and controlled release of IBU and DOX by MOFs-1, MOFs-2, MOFs-3, and MOFs-4 were then examined. In addition, the drug delivery efficiency of various MOFs with different ligands was investigated. PMID- 27697652 TI - Development of fluorescent thermoresponsive nanoparticles for temperature monitoring on membrane surfaces. AB - In this work, tris(phenantroline)ruthenium(II) chloride (Ru(phen)3) was immobilized in silica nanoparticles prepared according to the Stober method. Efforts were devoted on the optimization of the nano-thermometer in terms of size, polydispersity, intensity of the emission and temperature sensitivity. In particular, the immobilization of the luminophore in an external thin shell made of silica grown in a second step on bare silica nanoparticles allowed producing fluorescent monodisperse silica nanoparticles (420+/-20nm). A systematic study was addressed to maximize the intensity of the emission of the fluorescent nanoparticles by adjusting the concentration of Ru(phen)32+ in the shell from 0.2 to 24wt.%, whereas the thickness of the shell is affected by the amount of silica precursor employed. The luminescent activity of the doped nanoparticles was found to be sensitive to the temperature. In fact, the intensity of the emission linearly decreased by increasing the temperature from 20 degrees C to 65 degrees C. The thermoresponsive nanoparticles were functionalized with long aliphatic chains in order to obtain hydrophobic nanoparticles. The developed nanoparticles were immobilized via dip-coating procedure on the surface of hydrophobic porous membranes, such as Polyvinylidene fluoride (PVDF) prepared via Non-Solvent Induced Phase Separation (NIPS), providing local information about the membrane surface temperature.

AB - This work reports the green synthesis of the Cu/reduced graphene oxide/Fe3O4 (Cu/RGO/Fe3O4) nanocomposite as a new catalytic system for cyanation of aldehydes to nitriles. This nanocomposite catalytic system was synthesized by aqueous extract of leaves of Euphorbia bungei Boiss as a reducing and stabilizing agent. Various substituted aryl nitrile were prepared under optimized conditions and providing moderate to excellent yields. In this process the catalyst exhibited a strong magnet response and could be easily separated by an external magnet and reused with no loss of catalytic activity. PMID- 27697654 TI - Effects of first-row transition metals and impregnation ratios on the physicochemical properties of microwave-assisted activated carbons from wood biomass. AB - First-row transition metals (Co, Ni, Cu and Zn) were successfully used in the preparation of activated carbons from wood biomass via microwave-assisted irradiation. Physical-chemical properties of the produced materials (MWAC) were studied by nitrogen adsorption-desorption curves, SEM, FTIR, UV-vis DRS and synchronous fluorescence spectroscopy, CHN elemental analysis, TGA/DTG, pHzpc, hydrophobic properties, and total acidity and basicity groups. Results showed that the metals were bound successfully in different amounts with surface functional groups of the wood biomass through ion exchange and surface complexation interaction during the impregnation step. Zn2+ and Cu2+ formed the most complexes. MWAC impregnated with Zn2+ showed higher pore volumes and surface areas, followed by Cu2+, Co2+ and Ni2+, independently of the ratio used. As the metal : biomass ratio was increased from 0.5 to 2, the surface area of MWAC increased from 300 to 620m2g-1 for Co-MC, 260 to 381m2g-1 for Ni-MC, 449 to 765m2g-1 for Cu-MC and from 572 to 1780m2g-1 for Zn-MC. The samples showed high values of carbon contents and oxygen-containing groups. An adsorption experiment revealed that samples prepared using ZnCl2 showed the highest sorption capacities (qe) for the tested adsorbates, followed by CuCl2, CoCl2 and NiCl2. These results matched with the surface areas and pore volumes trends, which were found to follow atomic number and melting point trends-Ni(II)bisphenol A>hydroquinone>4-nitro phenol>2 naphtol>paracetamol>caffeine>resorcinol. PMID- 27697655 TI - Unmet oral health needs among persons with intellectual disability. AB - The aim of this study was to examine the factors affecting oral health status among intellectually disabled individuals in Serbia. The sample population was categorized according to age, sex, living arrangements, general health and the level of intellectual disability (ID). The diagnosis of dental caries was performed using the DMFT/dmft criteria. The oral hygiene and gingival health were assessed with the plaque index (Silness&Loe) and gingival index (Loe&Silness), respectively. Descriptive analysis, step-wise and logistic regression were performed to analyze related influential factors for caries presence, number of extracted teeth, teeth restored, the oral hygiene level and the extent of gingival inflammation. Odds ratios for caries were significantly higher among adult persons with ID, in persons with co-occurring developmental disorders (DDS) and increased with the level of ID. Group with DDS was associated with a 1.6 times greater odds of untreated decay, while the institutionalization was associated with 2.4 times greater odds of untreated decay. Institutionalization and co-occurring disabilities have been found to be significantly associated with a higher probability of developing gingivitis. Targeting oral health services to individuals with ID are encouraged and may help to reduce overall negative effect on oral and general health associated with delayed treatments, chronic dental pain, emergency dental care, tooth loss and advanced periodontal disease. PMID- 27697656 TI - Associations between sleep quality and inflammatory markers in patients with schizophrenia. AB - Sleep disorder is a risk factor for several systemic inflammation-related diseases and there are extensive data showing that schizophrenia is associated with chronic low-grade systemic inflammation. This study investigated the associations between sleep quality and inflammatory markers in patients with schizophrenia, which has not been examined before. Sleep quality (total sleep time, sleep efficiency, sleep onset latency, total activity counts, wake after sleep onset, number of awakening, and average length of awakening) was measured using actigraphy in 199 schizophrenia inpatients. The state of inflammation was measured using blood concentration of white blood cells (WBC) and neutrophils, together with neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR). The results showed that total sleep time was negatively associated with NLR and PLR, and sleep efficiency was negatively associated with neutrophil counts and NLR. Sleep onset latency, total activity counts, wake after sleep onset, and number of awakening were positively associated with WBC and neutrophil counts. The average length of awakening was positively associated with NLR and PLR. This is the first report to suggest that improving sleep quality may modulate the state of inflammation in patients with schizophrenia. PMID- 27697657 TI - Thwarted interpersonal needs and suicide ideation: Comparing psychiatric inpatients with bipolar and non-bipolar mood disorders. AB - Psychiatric inpatients are at heightened risk for suicide, and evidence suggests that psychiatric inpatients with bipolar mood disorders may be at greater risk for suicide ideation compared to those with non-bipolar mood disorders. There is a paucity of research directly comparing risk factors for suicide ideation in bipolar versus non-bipolar mood disorders in an inpatient sample. The current study sought to clarify the association between two constructs from the interpersonal theory of suicide (i.e., perceived burdensomeness and thwarted belongingness) in leading to suicide ideation among psychiatric inpatients with bipolar and non-bipolar mood disorders. Participants were (N=90) psychiatric inpatients with a bipolar (n = 20) or non-bipolar mood disorder (n=70; per their medical charts). Perceived burdensomeness, but not thwarted belongingness, was significantly associated with suicide ideation after adjusting for other covariates. This suggests perceived burdensomeness may play a key role in suicide ideation among psychiatric inpatients with any mood disorder and highlights the importance of assessment and intervention of perceived burdensomeness in this population. Contrary to our hypothesis, mood disorder group (i.e., bipolar versus non-bipolar) did not moderate the relations between perceived burdensomeness/thwarted belongingness and suicide ideation. PMID- 27697659 TI - An investigation of the speeding-related crash designation through crash narrative reviews sampled via logistic regression. AB - Speed is one of the most important factors in traffic safety as higher speeds are linked to increased crash risk and higher injury severities. Nearly a third of fatal crashes in the United States are designated as "speeding-related", which is defined as either "the driver behavior of exceeding the posted speed limit or driving too fast for conditions." While many studies have utilized the speeding related designation in safety analyses, no studies have examined the underlying accuracy of this designation. Herein, we investigate the speeding-related crash designation through the development of a series of logistic regression models that were derived from the established speeding-related crash typologies and validated using a blind review, by multiple researchers, of 604 crash narratives. The developed logistic regression model accurately identified crashes which were not originally designated as speeding-related but had crash narratives that suggested speeding as a causative factor. Only 53.4% of crashes designated as speeding-related contained narratives which described speeding as a causative factor. Further investigation of these crashes revealed that the driver contributing code (DCC) of "driving too fast for conditions" was being used in three separate situations. Additionally, this DCC was also incorrectly used when "exceeding the posted speed limit" would likely have been a more appropriate designation. Finally, it was determined that the responding officer only utilized one DCC in 82% of crashes not designated as speeding-related but contained a narrative indicating speed as a contributing causal factor. The use of logistic regression models based upon speeding-related crash typologies offers a promising method by which all possible speeding-related crashes could be identified. PMID- 27697658 TI - Distance-delivered interventions for PTSD: A systematic review and meta-analysis. AB - This systematic review and meta-analysis evaluated the efficacy of distance delivered, guided approaches to treatment (e.g., delivered via telephone, Internet, mail, videoconferencing) for clinical and subclinical posttraumatic stress disorder (PTSD). A comprehensive search yielded 19 randomized controlled trials (1491 participants) to be included. Meta-analyses revealed that distance delivered interventions led to significant within-group improvements in PTSD symptoms at post-treatment (g=0.81, 95% CI 0.65 to 0.97) and 3-6 month follow-up (g=0.78, 95% CI 0.59 to 0.97). Within-group depression and quality of life outcomes showed similar results, with medium post-treatment and follow-up effects. Compared to a waiting list, distance delivery (specifically, Internet treatments) led to superior PTSD outcomes (g=0.68, 95% CI 0.51 to 0.86). Compared to face-to-face interventions, distance delivery (specifically, videoconferencing treatments) did not result in significantly different PTSD outcomes at post treatment (g=-0.05, 95% CI -0.31 to 0.20) but led to inferior outcomes at 3-6 month follow-up (g=-0.25, 95% CI -0.44 to -0.07). Distance delivery of PTSD treatment is promising, but research is needed to determine its optimal use. PMID- 27697660 TI - Remarkable expression of vascular endothelial growth factor in bone marrow plasma cells of patients with POEMS syndrome. AB - Vascular endothelial growth factor (VEGF) is pathognomonically elevated in patients with POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes) syndrome. However, its source of overproduction is unclear. As clinical improvement is almost always associated with VEGF reduction after anti-plasma cell therapy, its increase at diagnosis has been attributed to the underlying monoclonal gammopathy, although direct evidence is still lacking. In the current study, we systemically measured VEGF levels in POEMS patients, before and after treatment. Bone marrow plasma cells showed remarkable VEGF expression, in both mRNA and protein levels, which decreased gradually in response to therapy. Of note, statistically linear correlations were observed between serum and bone marrow plasma cell VEGF levels (mRNA vs. serum, rho 0.343, p=0.003; protein vs. serum, rho 0.644, p<0.0001), supporting bone marrow plasma cells as the main source of circulating VEGF. Intriguingly, immunophenotyping revealed that bone marrow plasma cells were polyclonal in most patients at diagnosis. A clear monoclonal population, coexistent with polytypic cells, was only detectable in 11 cases (18%), in which comparable intracellular VEGF expression was observed between these two plasma cell populations (p=0.594), while monoclonal cells showed higher intracellular interleukin-6 expression (p=0.006). These patients had more serum monoclonal protein, less post therapeutic complete remission, and inferior overall (p=0.027) and progression free survival (p=0.002). Collectively, bone marrow plasma cells, mainly polyclonal population, are the major source of VEGF overproduction in POEMS patients. PMID- 27697662 TI - An image-invariant neural response to familiar faces in the human medial temporal lobe. AB - The ability to recognise familiar faces with ease across different viewing conditions contrasts with the inherent difficulty in the perception of unfamiliar faces across similar image manipulations. Models of face processing suggest that this difference is based on the neural representation for familiar faces being more invariant to changes in the image, than it is for unfamiliar faces. Here, we used an fMR-adaptation paradigm to investigate neural correlates of image invariant face recognition in face-selective regions of the human brain. Participants viewed faces presented in a blocked design. Each block contained different images of the same identity or different images from different identities. Faces in each block were either familiar or unfamiliar to the participants. First, we defined face-selective regions by comparing the response to faces with the response to scenes and scrambled faces. Next, we asked whether any of these face-selective regions showed image-invariant adaptation to the identity of a face. The core face-selective regions showed image-invariant adaptation to familiar and unfamiliar faces. However, there was no difference in the adaptation to familiar compared to unfamiliar faces. In contrast, image invariant adaptation for familiar faces, but not for unfamiliar faces, was found in face-selective regions of the medial temporal lobe (MTL). Taken together, our results suggest that the marked differences in the perception of familiar and unfamiliar faces may depend critically on neural processes in the medial temporal lobe. PMID- 27697661 TI - Possible role of intragenic DNA hypermethylation in gene silencing of the tumor suppressor gene NR4A3 in acute myeloid leukemia. AB - Expression of the tumor suppressor gene NR4A3 is silenced in the blasts of acute myeloid leukemia (AML), irrespective of the karyotype. Although the transcriptional reactivation of NR4A3 is considered to have a broad-spectrum anti leukemic effect, the therapeutic modalities targeting this gene have been hindered by our minimal understanding of the transcriptional mechanisms regulating its expression, particularly in human AML. Here we show the role of intragenic DNA hypermethylation in reducing the expression of NR4A3 in AML. Bisulfite sequencing analysis revealed that CpG sites at the intragenic region encompassing exon 3 of NR4A3, but not the promoter region, are hypermethylated in AML cell lines and primary AML cells. A DNA methyltransferase inhibitor restored the expression of NR4A3 following a reduction in DNA methylation levels at intragenic CpG sites. The in silico data revealed an enrichment of H3K4me1 and H2A.Z at exon 3 of NR4A3 in human non-malignant cells but that was excluded specifically in leukemia cells with CpG hypermethylation. This suggests that exon 3 represents a functional regulatory element involved in the transcriptional regulation of NR4A3. Our findings improve the current understanding of the mechanism underlying NR4A3 silencing and facilitate the development of NR4A3 targeted therapy.

AB - Motor resonance is the modulation of M1 corticospinal excitability induced by observation of others' actions. Recent brain imaging studies have revealed that viewing videos of grasping actions led to a differential activation of the ventral premotor cortex depending on whether the entire person is viewed versus only their disembodied hand. Here we used transcranial magnetic stimulation (TMS) to examine motor evoked potentials (MEPs) in the first dorsal interosseous (FDI) and abductor digiti minimi (ADM) during observation of videos or static images in which a whole person or merely the hand was seen reaching and grasping a peanut (precision grip) or an apple (whole hand grasp). Participants were presented with six visual conditions in which visual stimuli (video vs static image), view (whole person vs hand) and grasp (precision grip vs whole hand grasp) were varied in a 2 * 2 * 2 factorial design. Observing videos, but not static images, of a hand grasping different objects resulted in a grasp-specific interaction, such that FDI and ADM MEPs were differentially modulated depending on the type of grasp being observed (precision grip vs whole hand grasp). This interaction was present when observing the hand acting, but not when observing the whole person acting. Additional experiments revealed that these results were unlikely to be due to the relative size of the hand being observed. Our results suggest that observation of videos rather than static images is critical for motor resonance. Importantly, observing the whole person performing the action abolished the grasp specific effect, which could be due to a variety of PMv inputs converging on M1.

AB - The aim of the study was to investigate experimentally the impact of current mood state on anosognosia or awareness of symptoms in AD patients, in which mood state was manipulated by giving tasks that were either easy (success condition) or very difficult (failure condition). Twenty-two patients with mild to moderate AD participated. Four success-failure manipulation (SFM) computerized tasks were used as mood induction procedures, two based on reaction time tasks and the other on memory tasks. Level of awareness and the current mood state were assessed before and after each task, using a modified version of the Anosognosia Questionnaire for Dementia and a self-reported questionnaire respectively. For both types of task, the results indicate that the emotional state of the participants was similar before performing the tasks and that only the failure conditions induced a negative mood state. Additionally, regarding the level of awareness, there were no significant differences after the reaction time tasks but for the memory tasks, there was greater awareness of symptoms after performing the task in the failure condition. To the best of our knowledge, this study is the first exploring experimentally the impact of mood on anosognosia in AD. The results showed an improvement of awareness of symptoms after negative mood induction, but only when the task used in the SFM was memory-based. PMID- 27697665 TI - Augmenting distractor filtering via transcranial magnetic stimulation of the lateral occipital cortex. AB - Visual selective attention (VSA) optimizes perception and behavioral control by enabling efficient selection of relevant information and filtering of distractors. While focusing resources on task-relevant information helps counteract distraction, dedicated filtering mechanisms have recently been demonstrated, allowing neural systems to implement suitable policies for the suppression of potential interference. Limited evidence is presently available concerning the neural underpinnings of these mechanisms, and whether neural circuitry within the visual cortex might play a causal role in their instantiation, a possibility that we directly tested here. In two related experiments, transcranial magnetic stimulation (TMS) was applied over the lateral occipital cortex of healthy humans at different times during the execution of a behavioral task which entailed varying levels of distractor interference and need for attentional engagement. While earlier TMS boosted target selection, stimulation within a restricted time epoch close to (and in the course of) stimulus presentation engendered selective enhancement of distractor suppression, by affecting the ongoing, reactive instantiation of attentional filtering mechanisms required by specific task conditions. The results attest to a causal role of mid-tier ventral visual areas in distractor filtering and offer insights into the mechanisms through which TMS may have affected ongoing neural activity in the stimulated tissue.

PMID- 27697667 TI - Life-course risk factor levels and coronary artery calcification. The Cardiovascular Risk in Young Finns Study. AB - BACKGROUND: Risk factors measured in early life have been shown to predict coronary artery calcium (CAC) in adulthood. However, limited data exist on when risk factor profiles of those who develop CAC diverge from those who do not. We investigated the associations of coronary heart disease risk factor trajectories beginning in adolescence and CAC measured at middle-age. METHODS: CAC was measured among 589 participants aged 39-45years in whom cardiovascular risk factors (serum lipids, blood pressure, body mass index, physical activity, smoking habits, and fruit, vegetable, fish, and butter intake) had been collected in 1980, 1983, 1986, 2001, and 2007 as part of the Cardiovascular Risk in Young Finns Study. RESULTS: Mean levels of low-density lipoprotein cholesterol (LDL-C), total cholesterol, apolipoprotein B (Apo-B), and systolic blood pressure (SBP) levels across the 27-year period were significantly higher among those with CAC vs. those without. The difference between the groups was 0.25mmol/l (95% confidence interval, 95%CI, 0.079-0.41) for LDL-C, 0.26mmol/l (95%CI 0.080-0.44) for total cholesterol, 0.05mmol/l (95%CI 0.0085-0.091) for Apo-B and 1.92mmHg (95%CI 0.10-3.74) for SBP after adjustment for other risk factors. Those with CAC at age 39-45years had higher serum lipid levels already in adolescence or early adulthood compared with those without CAC, with these differences becoming more pronounced during the life-course. CONCLUSIONS: Long-time risk factor exposure to higher LDL-C, total cholesterol and Apo-B levels already starting in adolescence and higher SBP levels in adulthood is associated with CAC at middle-age. PMID- 27697668 TI - Brain delivery of microencapsulated GDNF induces functional and structural recovery in parkinsonian monkeys. AB - Glial cell line-derived neurotrophic factor (GDNF) remains the most potent neurotrophic factor for dopamine neurons. Despite its potential as treatment for Parkinson's disease (PD), its clinical application has been hampered by safety and efficacy concerns associated with GDNF's short in vivo half-life and with significant brain delivery obstacles. Drug formulation systems such as microparticles (MPs) may overcome these issues providing protein protection from degradation and sustained drug release over time. We therefore sought to evaluate the efficacy and safety of GDNF delivered via injectable biodegradable MPs in a clinically relevant model of PD and to investigate the mechanism contributing to their beneficial effects. MPs were injected unilaterally into the putamen of parkinsonian monkeys with severe nigrostriatal degeneration. Notably, a single administration of the microencapsulated neurotrophic factor achieved sustained GDNF levels in the brain, providing motor improvement and dopaminergic function restoration. This was reflected by a bilateral increase in the density of striatal dopaminergic neurons 9 months after treatment. Moreover, GDNF was retrogradely transported to the substantia nigra increasing bilaterally the number of dopaminergic and total neurons, regardless of the severe degeneration. GDNF-MP injection within the putamen elicited no adverse effects such as immunogenicity, cerebellar degeneration or weight loss. MPs are therefore a safe, efficient vehicle for sustained protein delivery to the brain, supporting the therapeutic benefit of GDNF when encapsulated within MPs for brain repair. Overall, these findings constitute important groundwork for GDNF-MP clinical development. PMID- 27697669 TI - Regenerated silk materials for functionalized silk orthopedic devices by mimicking natural processing. AB - Silk fibers spun by silkworms and spiders exhibit exceptional mechanical properties with a unique combination of strength, extensibility and toughness. In contrast, the mechanical properties of regenerated silk materials can be tuned through control of the fabrication process. Here we introduce a biomimetic, all aqueous process, to obtain bulk regenerated silk-based materials for the fabrication of functionalized orthopedic devices. The silk materials generated in the process replicate the nano-scale structure of natural silk fibers and possess excellent mechanical properties. The biomimetic materials demonstrate excellent machinability, providing a path towards the fabrication of a new family of resorbable orthopedic devices where organic solvents are avoided, thus allowing functionalization with bioactive molecules to promote bone remodeling and integration. PMID- 27697670 TI - Synergistic antitumor activity of rapamycin and EF24 via increasing ROS for the treatment of gastric cancer. AB - Mechanistic/mammalian target of rapamycin (mTOR) has emerged as a new potential therapeutic target for gastric cancer. Rapamycin and rapamycin analogs are undergoing clinical trials and have produced clinical responses in a subgroup of cancer patients. However, monotherapy with rapamycin at safe dosage fails to induce cell apoptosis and tumor regression which has hampered its clinical application. This has led to the exploration of more effective combinatorial regimens to enhance the effectiveness of rapamycin. In our present study, we have investigated the combination of rapamycin and a reactive oxygen species (ROS) inducer EF24 in gastric cancer. We show that rapamycin increases intracellular ROS levels and displays selective synergistic antitumor activity with EF24 in gastric cancer cells. This activity was mediated through the activation of c-Jun N terminal kinase and endoplasmic reticulum stress (ER) pathways in cancer cells. We also show that inhibiting ROS accumulation reverses ER stress and prevents apoptosis induced by the combination of rapamycin and EF24. These mechanisms were confirmed using human gastric cancer xenografts in immunodeficient mice. Taken together, our work provides a novel therapeutic strategy for the treatment of gastric cancer. The work reveals that ROS generation could be an important target for the development of new combination therapies for cancer treatment. PMID- 27697672 TI - A computational model for investigating the effects of changes in bioavailability of insulin-like growth factor-1 on the homeostasis of the intervertebral disc. AB - Insulin-like growth factor-1 (IGF-1) is well-known for upregulating cell proliferation and biosynthesis of the extracellular matrix in the intervertebral disc (IVD). Pathological conditions, such as obesity or chronic kidney disease cause IGF-1 deficiency in plasma. How this deficiency impacts disc homeostasis remains unknown. Pro-anabolic approaches for the treatment of disc degeneration based on enhancing IGF-1 bioavailability to tissue-cells are considered, but knowledge of their effectiveness in enhancing cellular anabolism of a degenerated disc is limited. In this study, we developed a computational model for disc homeostasis specifically addressing the role of IGF-1 in modulating both extracellular matrix biosynthesis and cellularity in the IVD. This model was applied to investigate how changes in IGF-1 bioavailability, namely deficiency or enhancement of growth factor, affect disc health. In this study, it was found that IGF-1 deficiency mainly affects the biosynthesis of ECM components, especially in the most external regions of the IVD such as the cartilage endplates and the outer portion of annulus fibrosus. Also, a total of three approaches for increasing IGF-1 bioavailability as a therapy for degenerated IVDs were investigated. It was found that all these strategies are only beneficial to those disc regions receiving sufficient nutritional supply (i.e., the outmost IVD regions), while they exacerbate tissue degradation in malnourished regions (i.e., inner portion of the disc). This suggests that pro-anabolic growth factor-based therapies are limited in that their success strongly depends on an adequate nutritional supply to the IVD tissue, which is not guaranteed in degenerated discs. PMID- 27697671 TI - Reducing risk for anxiety and depression in adolescents: Effects of a single session intervention teaching that personality can change. AB - Efforts to reduce youth mental health problems have advanced greatly but have not lowered overall rates of youth mental illness. Thus, a need exists for disseminable, mechanism-targeted approaches to reducing risk of youth psychopathology. Accordingly, we conducted a randomized-controlled trial testing whether a single-session intervention teaching growth personality mindsets (the belief that personality is malleable) reduced known risk factors for anxiety and depression in adolescents experiencing or at risk for internalizing problems (N = 96, ages 12-15). Compared to a supportive-therapy control, a 30-min computer guided mindset intervention strengthened adolescents' perceived control; this improvement was associated with increases in growth mindsets. Further, electrodermal activity recovery slopes showed that youths receiving the mindset intervention recovered from a lab-based social stressor over three times as fast as control group youths. Improvements in growth mindsets and perceived control were linked with faster stress recovery. Results suggest a disseminable strategy for reducing internalizing problem risk among adolescents. PMID- 27697673 TI - Proteome changes associated with dormancy release of Dongxiang wild rice seeds. AB - Seed dormancy provides optimum timing for seed germination and subsequent seedling growth, but the mechanism of seed dormancy is still poorly understood. Here, we used Dongxiang wild rice (DXWR) seeds to investigate the dormancy behavior and the differentially changed proteome in embryo and endosperm during dormancy release. DXWR seed dormancy was caused by interaction of embryo and its surrounding structure, and was an intermediate physiological dormancy. During seed dormancy release, a total of 109 and 97 protein spots showed significant change in abundance and were successfully identified in embryo and endosperm, respectively. As a result of dormancy release, the abundance of nine proteins involved in storage protein, cell defense and rescue and energy changed in the same way in both embryo and endosperm, while 67 and 49 protein spots changed differentially in embryo and endosperm, respectively. Dormancy release of DXWR seeds was closely associated with degradation of storage proteins in both embryo and endosperm. At the same time, the abundance of proteins involved in metabolism, glycolysis and TCA cycle, cell growth and division, protein synthesis and destination and signal transduction increased in embryos while staying constant or decreasing in endosperms. PMID- 27697674 TI - Levels of the soluble LDL receptor-relative LR11 decrease in overweight individuals with type 2 diabetes upon diet-induced weight loss. AB - BACKGROUND AND AIMS: Cardiovascular disease (CVD) is a major complication in patients with type 2 diabetes (T2D), especially in those with obesity. Plasma soluble low density lipoprotein receptor-relative with 11 ligand-binding repeats (sLR11) plays a role in the development of atherosclerosis and has been linked to the metabolism of triglyceride-rich lipoproteins, adiposity, and vascular complications in T2D. We aimed to determine the effect of diet-induced weight loss on plasma sLR11 levels in overweight and obese individuals with T2D. METHODS: Plasma sLR11 levels were determined in 64 individuals with T2D and BMI >27 kg/m2 before and after a 20-week weight loss diet. As a reference, sLR11 levels were also determined in 64 healthy, non-obese controls, matched as a group for age and sex. RESULTS: Median plasma sLR11 levels of the T2D study-group at baseline (15.4 ng/mL (IQR 12.9-19.5)) were higher than in controls (10.2 (IQR: 8.7-12.2) ng/mL; p = 0.001). The diet resulted in a weight loss of 9.7 +/- 5.2% (p = 0.001) and improved CVD risk factors. sLR11 levels were reduced to 13.3 ng/mL (IQR 11.0-17.1; p = 0.001). Changes in sLR11 levels positively associated with changes in non-HDL cholesterol (B = 1.54, R2 = 0.17, p = 0.001) and HbA1c (B = 0.07, R2 = 0.11, p = 0.007), but not with weight loss (B = 0.04, R2 = 0.05, p = 0.076). The changes in non-HDL cholesterol and HbA1c together explained 24% of the variance of sLR11 reduction (p = 0.001). CONCLUSIONS: Weight loss dieting in overweight and obese individuals with T2D resulted in a reduction in plasma sLR11 levels that was associated with improvements in lipid-profile and glycemic state. PMID- 27697675 TI - Goserelin plus tamoxifen compared to chemotherapy followed by tamoxifen in premenopausal patients with early stage-, lymph node-negative breast cancer of luminal A subtype. AB - OBJECTIVES: To study the outcomes of adjuvant goserelin combined with tamoxifen (GosTam) compared to chemotherapy followed by tamoxifen (ChemTam) in premenopausal patients with early stage, luminal A breast cancer. METHODS: From 2008 until 2013, data were retrospectively collected for premenopausal patients who underwent surgery for invasive tumors that were <=2.0 cm, node-negative, strongly positive for estrogen and progesterone receptors, HER-2-negative, and Ki 67 < 25%. The patients were divided into two groups according to adjuvant regimen, either GosTam or ChemTam. All patients who underwent different adjuvant regimens were excluded. RESULTS: In total, 235 patients underwent GosTam and 171 patients underwent ChemTam. There were significantly more patients younger than 40 years in the GosTam group (32% GosTam vs. 22% ChemTam, p = 0.031). Mean tumor size was significantly smaller (1.19 cm vs. 1.48 cm, p < 0.001), Ki-67 significantly lower (p = 0.049), and nuclear grade was low in a significant number of patients in the GosTam group (2% vs. 13%, p < 0.001). After a median follow-up of 51.3 months, there was no mortality in either group. There was no significant difference in 5-year disease-free survival (DFS) between the two groups even after univariate analysis considering age, tumor size, nuclear grade, and P53% (GosTam = 98.9% vs. ChemTam = 95.7%, HR = 0.404, 95% CI = [0.073, 2.222], p = 0.248). CONCLUSION: There was no difference between treatment groups, and neither chemotherapy nor ovarian suppression seemed to improve the outcome. Thus, tamoxifen alone might be a sufficient option for this low-risk patient population. PMID- 27697676 TI - A comparison of patient-centered economic and clinical outcomes of post mastectomy breast reconstruction between obese and non-obese patients. AB - BACKGROUND: The objectives of this study were to compare, by patient obesity status, the contemporary utilization patterns of different reconstruction surgery types, understand postoperative complication profiles in the community setting, and analyze the financial impact on health care payers and patients. METHODS: Using data from the MarketScan Health Risk Assessment Database and Commercial Claims and Encounters Database, we identified breast cancer patients who received breast reconstruction surgery following mastectomy between 2009 and 2012. The Cochran-Armitage test was used to evaluate the utilization pattern of breast reconstruction surgery. Multivariable logistic regressions were used to estimate the association between obesity status and infectious, wound, and perfusion complications within one year of surgery. A generalized linear model was used to compare total, complication-related, and out-of-pocket costs. RESULTS: The rate of TE/implant-based reconstruction increased significantly for non-obese patients but not for obese patients during the years analyzed, whereas autologous reconstruction decreased for both patient groups. Obesity was associated with higher odds of infectious, wound, and perfusion complications after TE/implant based reconstruction, and higher odds of perfusion complications after autologous reconstruction. The adjusted total healthcare costs and out-of-pocket costs were similar for obese and non-obese patients for either type of breast reconstruction surgery. CONCLUSIONS: A greater likelihood of one-year complications arose from TE/implant-based vs autologous reconstruction surgery in obese patients. Given that out-of-pocket costs were independent of the type of reconstruction, greater emphasis should be placed on conveying the surgery-related complications to obese patients to aid in patient-based decision making with their plastic surgeons and oncologists. PMID- 27697677 TI - A study of the relationship between the study process, motivation resources, and motivation problems of nursing students in different educational systems. AB - BACKGROUND: The study process is related to students' learning approaches and styles. Motivation resources and problems determine students' internal, external, and negative motivation. Analyzing the study process and motivation of students yields important indications about the nature of educational systems in higher education. OBJECTIVES: This study aims to analyze the relationship between the study process, and motivation resources and problems with regard to nursing students in different educational systems in Turkey and to reveal their effects according to a set of variables. DESIGN: This is a descriptive, cross-sectional and correlational study. SETTINGS: Traditional, integrated and problem-based learning (PBL) educational programs for nurses involving students from three nursing schools in Turkey. PARTICIPANTS: Nursing students (n=330). METHODS: The data were collected using the Study Process Questionnaire (R-SPQ-2F) and the Motivation Resources and Problems (MRP) Scale. RESULTS: A statistically significant difference was found between the scores on the study process scale, and motivation resources and problems scale among the educational systems. This study determined that the mean scores of students in the PBL system on learning approaches, intrinsic motivation and negative motivation were higher. A positive significant correlation was found between the scales. CONCLUSIONS: The study process, and motivation resources and problems were found to be affected by the educational system. This study determined that the PBL educational system more effectively increases students' intrinsic motivation and helps them to acquire learning skills. PMID- 27697678 TI - Nursing students' changing orientation and attitudes towards nursing during education: A two year longitudinal study. AB - BACKGROUND: Previous studies have shown that nursing students' perceptions of nursing change over time. Little research has been undertaken in the Netherlands of students entering nursing programmes and of how they progress. OBJECTIVES: The aims of this study were to explore whether nursing students' orientation and attitudes towards nursing changed over time, when these changes occurred, and what factors influenced the changes. We also aimed to identify the factors which prompted them to consider leaving their programmes, and what factors affected their motivation to stay. DESIGN: The study used a longitudinal quantitative design. PARTICIPANTS: Questionnaires were administered to all students enrolled in a Bachelor's of Nursing programme at four nursing universities of applied sciences in the Netherlands (n=1414). The data for this study were collected during the first two years of the programme, from September 2011 to June 2013. A total of 123 respondents completed the survey each year and this group was used to examine changes over time. METHODS: At four time intervals respondents completed a survey consisting of 1) the Nursing Orientation Tool, 2) the Nursing Attitude Questionnaire and 3) background characteristics. Non-parametric tests were used to explore changes in factor scores over time. RESULTS: The results showed an improvement in the students' orientation and attitudes towards knowledge, skills and the professional roles of nurses, while empathic behaviour decreased over time. Although the changes showed non-linear patterns over time, the results showed clear effects between the different time points. The reasons for attrition (24%) proved to be related both to problems with the educational programme and to personal problems. An important motivator for students to stay in the course was their passionate desire to become nurses, suggesting that the positive aspects of a nursing career dominated the problems they encountered. CONCLUSIONS: Tutors and mentors should pay more attention to the individual perceptions and problems of first and second-year students, both in the classroom and during clinical placements. Knowledge of the students' perceptions from the very beginning could be vital to study success. PMID- 27697679 TI - Creating stories for learning about the neonatal care experience through the eyes of student nurses: An interpretive, narrative study. AB - BACKGROUND: Storytelling is an increasingly well recognised and valued platform to learn about the human experience within healthcare. Little is known however about how stories can enhance understanding in neonatal care, a specialised field offering rich opportunities for learning. This study focuses on the creation of stories based on the experiences of student nurses to inform teaching and learning strategies in the neonatal field. OBJECTIVES: The study aimed to create stories from the narratives of student nurses working within the neonatal field and identify what key themes for learning emerged in order to develop a storytelling resource to share experiences with their peers. DESIGN: An interpretive, constructivist approach was used to collect, analyse and create stories from student nurse's experiences, in line with narrative inquiry. PARTICIPANTS: Six pre-registration children's nursing students were selected by purposive sampling. SETTINGS: Interviews were undertaken within six weeks following placement completion in an agreed location. METHODS: Narratives were obtained by semi-structured interviews. Narrative analysis and core story creation was undertaken to construct stories and key learning themes emerged which provided the pedagogical basis for subsequent digital resource development. FINDINGS: Key themes emerged relating to the insight and observances of student nurses and the neonatal journey they had experienced, including the nature of neonatal care, experiences of the neonate and parents, the environment and their own learning transition. Preliminary peer evaluation of the storytelling resource revealed storytelling as an interesting and novel approach to teaching & learning, learning from ones' peers, preparation for practice and a valuable insight into a new specialist area. CONCLUSIONS: The study has value to teaching and learning by enabling an appreciation of how narrative can be used to portray the experiences of learners. Findings also support an approach to analysing narrative to create stories for learning and inform subsequent digital resource development. PMID- 27697680 TI - Developing a vacuum thermal stripping - acid absorption process for ammonia recovery from anaerobic digester effluent. AB - To prevent acetoclastic methanogens from ammonia inhibition in anaerobic digestion of protein-rich substrates, ammonia needs to be removed or recovered from digestate. This paper presents an innovative ammonia recovery process that couples vacuum thermal stripping with acid absorption. Ammonia is stripped out of digestate boiling at a temperature below the normal boiling point due to vacuum. Stripped ammonia is absorbed to a sulfuric acid solution, forming ammonium sulfate crystals as a marketable product. Three common types of digestate were found to have boiling point temperature-vacuum curves similar to water. Seven combinations of boiling temperature and vacuum (50 degrees C 16.6 kPa, 58 degrees C 20.0 kPa, 65 degrees C 25.1 kPa, 70 degrees C 33.6 kPa, 80 degrees C 54.0 kPa, 90 degrees C 74.2 kPa, and 100 degrees C 101.3 kPa) were tested for batch stripping of ammonia in dairy manure digestate. 93.3-99.9% of ammonia was stripped in 3 h. The Lewis-Whitman model fitted ammonia stripping process well. Ammonia mass transfer coefficient was significantly higher at boiling temperature 65-100 degrees C and vacuum pressure 25.1-101.3 kPa than 50-58 degrees C and 16.6-20.0 kPa. The low ammonia saturation concentrations (0-24 mg N/L) suggested a large driving force to strip ammonia. The optimum boiling point temperature - vacuum pressure for ammonia recovery in a recirculation line of a mesophilic digester was 65 degrees C and 25.1 kPa, at which the ammonia mass transfer coefficient was as high as 37.3 mm/h. Installation of a demister and liquid trap could avoid negative effects of higher stripping temperature and stronger vacuum on formation of ammonium sulfate crystals. Pilot tests demonstrated that high purity ammonium sulfate crystals could be produced by controlling sulfuric acid content and maintaining acid solution saturated with ammonium sulfate. Although volatile organic compounds such as cyclohexene were found in the final acid solutions, no volatile organic compounds were found in the recovered crystals. PMID- 27697681 TI - Characterization of anaerobic granular sludge using a rheological approach. AB - High-rate anaerobic granular sludge reactors have been developed and are widely used for wastewater treatment. An accurate estimate of sludge rheological properties is required for the design and efficient operation of the digestion process. The present work determined the rheological behavior of anaerobic granular sludge obtained from a full-scale bioreactor at different solid concentrations, operation temperatures and particle sizes, and highlighted common features in flow and dynamic measurements. The granular sludge showed a shear thinning behavior with a yield stress under flow measurements and a viscoelastic property in dynamic measurements. The structure of granules was nearly temperature-independent in the range of operational temperature (20-70 degrees C), but the total solid concentration and particle size had significant effects on not only the rheological properties, but also the operation of the bioreactors. In addition, anaerobic granular sludge could cross over from the strong-link regime to the weak-link regime as the solid concentration increased. Furthermore, we adopted a Wagner-type constitutive model to describe the time dependent and non-linear viscoelastic behaviors of anaerobic granular sludge, and then evaluated its validity and limitation. PMID- 27697682 TI - Polyhydroxyalkanoate synthesis by mixed microbial consortia cultured on fermented dairy manure: Effect of aeration on process rates/yields and the associated microbial ecology. AB - Polyhydroxyalkanoates (PHAs) are biodegradable polymers that can substitute for petroleum-based plastics in a variety of applications. One avenue to commercial PHA production involves coupling waste-based synthesis with the use of mixed microbial consortia (MMC). In this regard, production requires maximizing the enrichment of a MMC capable of feast-famine PHA synthesis, with the metabolic response induced through imposition of aerobic-dynamic feeding (ADF) conditions. However, the concept of PHA production in complex matrices remains unrefined; process operational improvements are needed, along with an enhanced understanding of the MMC. Research presented herein investigated the effect of aeration on feast-famine PHA synthesis, with four independent aeration state systems studied; MMC were fed volatile fatty acid (VFA)-rich fermented dairy manure. Regardless of the aeration state, all MMC exhibited a feast-famine response based on observed carbon cycling. Moreover, there was no statistical difference in PHA synthesis rates, with qPHA ranging from 0.10 to 0.19 CmmolPHA gVSS-1 min-1; VFA uptake rates exhibited similar statistical indifferences. PHA production assessments on the enriched MMC resulted in maximum intracellular concentrations ranging from 22.5 to 90.7% (mgPHA mgVSS-1); at maximum concentration, the mean hydroxyvalerate mol content was 73 +/- 0.6%. While a typical feast-famine dissolved oxygen (DO) pattern was observed at maximum aeration, less resolution was observed at decreasing aeration rates, suggesting that DO may not be an optimal process monitoring parameter. At lower aeration states, nitrogen cycling patterns, supported by molecular investigations targeting AOBs and NOBs, indicate that NO2 and NO3 sustained feast-famine PHA synthesis. Next-generation sequencing analysis of the respective MMC revealed numerous and diverse genera exhibiting the potential to achieve PHA synthesis, suggesting functional redundancy embedded in the diverse MMC. Ultimately, results demonstrate that aeration can be controlled in waste-based ADF systems to sustain PHA production potential, while enriching for a diverse MMC that exhibits potential functional redundancy. Reduced aeration could also enhance cost competitiveness of waste-based PHA production, with potential further benefits associated with nitrogen treatment. PMID- 27697683 TI - Chloramines in a pilot-scale water distribution system: Transformation of 17beta estradiol and formation of disinfection byproducts. AB - The degradation and transformation products of 17beta-estradiol (E2) by chloramines in a pilot-scale water distribution system (WDS) were investigated using varying conditions including multiple mass ratios of chlorine to nitrogen (Cl/N), changing concentrations of chloramines, and different pH and pipe materials. The degradation of E2 was complete in <=9 h in both deionized water (DW) and in the WDS under studied conditions. When the degradation rate of E2 was compared in WDS and DW, the degradation rate was appreciably greater in the WDS than in the DW at Cl/N mass ratios of 3, 4 and 6. However, at Cl/N mass ratios of 8 and 9, degradation was faster in the DW than in the WDS. The degradation rate of E2 was greatly affected by the initial total chloramine concentration, and the degradation of E2 in DW was consistent with second-order kinetics. The degradation rate of E2 in both the DW and the WDS increased with increasing pH. The order of degradation rate of E2in different pipes was: ductile iron loop (loop A) > polyethylene (PE) loop (loop B)> stainless steel loop (loop C). Ten specific degradation products of E2, produced by chloramination, were identified. Most of the degradation products of E2 chloramination were stable for more than 10 h. The degradation pathways of E2 in the WDS are proposed and briefly discussed. The concentrations of trihalomethanes (THMs), haloacetic acids (HAAs), and halogenated nitromethane (HNMs) during the degradation E2 in WDS were also determined. PMID- 27697684 TI - Distributions, abundances and activities of microbes associated with the nitrogen cycle in riparian and stream sediments of a river tributary. AB - River tributaries are ecologically important environments that function as sinks of inorganic nitrogen. To gain greater insight into the nitrogen cycle (N-cycle) in these environments, the distributions and activities of microbial populations involved in the N-cycle were studied in riparian and stream sediments of the Santa Fe River (SFR) tributaries located in northern Florida, USA. Riparian sediments were characterized by much higher organic matter content, and extracellular enzyme activities, including cellobiohydrolase, beta-d-glucosidase, and phenol oxidase than stream sediments. Compared with stream sediments, riparian sediments exhibited significantly higher activities of nitrification, denitrification, dissimilatory nitrate reduction to ammonia (DNRA) and anaerobic ammonia oxidation; correspondingly, with higher copies of amoA (a biomarker for enumerating nitrifiers), nirS and nirK (for denitrifiers), and nrfA (for DNRA bacteria). Among N-cycle processes, denitrification showed the highest activities and the highest concentrations of the corresponding gene (nirK and nirS) copy numbers. In riparian sediments, substantial nitrification activities (6.3 mg-N kg soil-1d-1 average) and numbers of amoA copies (7.3 * 107 copies g soil-1 average) were observed, and nitrification rates correlate with denitrification rates. The guild structures of denitrifiers and nitrifiers in riparian sediments differed significantly from those found in stream sediments, as revealed by analysis of nirS and archaeal amoA sequences. This study shows that riparian sediments serve as sinks for inorganic nitrogen loads from non-point sources of agricultural runoff, with nitrification and denitrification associated with elevated levels of carbon and nitrogen contents and extracellular enzyme activities. PMID- 27697685 TI - Sludge bio-drying: Effective to reduce both antibiotic resistance genes and mobile genetic elements. AB - Sewage sludge is considered as one of major contributors to the increased environmental burden of ARGs. Sludge bio-drying was increasingly adopted due to its faster sludge reduction compared with composting. The fate of ARGs during full-scale sludge bio-drying was investigated to determine whether it could effectively reduce ARGs, and the contributions of bacterial community, horizontal gene transfer (HGT) through mobile genetic elements (MGEs) and co-selection from heavy metals to ARGs profiles were discussed in detail. Two piles with different aeration strategies (Pile I, the improved and Pile II, the control) were operated to elucidate effects of aeration strategy on ARGs profiles. Results showed that sludge bio-drying could effectively reduce both most of targeted ARGs (0.4-3.1 logs) and MGEs (0.8-3.3 logs) by the improved aeration strategy, which also enhanced both the sludge bio-drying performance and ARGs reduction. The enrichment of ARGs including ermF, tetX and sulII could be well explained by the evolution of bioavailable heavy metals, not HGT through MGEs, and their potential host bacteria mainly existed in Bacteroidetes. Although changes of bacterial community contributed the most to ARGs profiles, HGT through MGEs should be paid more attention especially in the thermophilic stage of sludge bio-drying. PMID- 27697686 TI - Impact of fulvic acids on bio-methanogenic treatment of municipal solid waste incineration leachate. AB - A considerable amount of leachate with high fulvic acid (FA) content is generated during the municipal solid waste (MSW) incineration process. This incineration leachate is usually processed by downstream bio-methanogenic treatment. However, few studies have examined the impact that these compounds have on methanogenesis and how they are degraded and transformed during the treatment process. In this study, a laboratory-scale expanded granular sludge bed (EGSB) reactor was operated with MSW incineration leachate containing various concentrations of FA (1500 mg/L to 8000 mg/L) provided as the influent. We found that FA degradation rates decreased from 86% to 72% when FA concentrations in the reactor were increased, and that molecular size, level of humification and aromatization of the residual FA macromolecules all increased after bio-methanogenic treatment. Increasing FA influent concentrations also inhibited growth of hydrogenotrophic methanogens from the genus Methanobacterium and syntrophic bacteria from the genus Syntrophomonas, which resulted in a decrease in methane production and a concomitant increase in CO2 content in the biogas. Sequences most similar to species from the genus Anaerolinea went up as FA concentrations increased. Bacteria from this genus are capable of extracellular electron transfer and may be using FA as an electron acceptor for growth or as a shuttle for syntrophic exchange with other microorganisms in the reactor. In order to determine whether FA could serve as an electron shuttle to promote syntrophy in an anaerobic digester, co-cultures of Geobacter metallireducens and G. sulfurreducens were grown in the presence of FA from raw leachate or from residual bioreactor effluent. While raw FA stimulated electron transfer between these two bacteria, residual FA did not have any electron shuttling abilities, indicating that FA underwent a significant transformation during the bio-methanogenic treatment process. These results are significant and should be taken into consideration when optimizing anaerobic bioreactors used to treat MSW incineration leachate high in FA content. PMID- 27697687 TI - Drivers of nitrous oxide accumulation in denitrification biofilters with low carbon:nitrogen ratios. AB - Heterotrophic denitrification is usually inhibited by insufficient carbon sources; however, the underlying mechanisms responsible for nitrous oxide (N2O) accumulation within denitrification at low carbon:nitrogen (C/N) ratios have not been quantified from a molecular level. In this study, five denitrification biofilters were developed and exhibited efficiency (total nitrogen: 18.5%-92.2%; nitrate nitrogen: 42.9%-99.5%; chemical oxygen demand: 50.5%-93.7%) in remediating micro-polluted water with C/N ratios ranging between 0.65 and 3.0. A combined analysis revealed that the coupling of anaerobic ammonium oxidation (ANAMMOX) and denitrification accounted for N2O accumulation in the biofilters, and the key drivers of the N2O accumulation rates were qnorB/nirK, nosZ/(narG + napA), amx/(nirS + nirK), narG/bacteria and qnorB/bacteria. Our study demonstrated that genetic association was indicative of microbial processes relative to nitrogen cycling and reflected N2O flux within denitrification biofilters at low C/N ratios. PMID- 27697688 TI - Biofouling in forward osmosis systems: An experimental and numerical study. AB - This study evaluates with numerical simulations supported by experimental data the impact of biofouling on membrane performance in a cross-flow forward osmosis (FO) system. The two-dimensional numerical model couples liquid flow with solute transport in the FO feed and draw channels, in the FO membrane support layer and in the biofilm developed on one or both sides of the membrane. The developed model was tested against experimental measurements at various osmotic pressure differences and in batch operation without and with the presence of biofilm on the membrane active layer. Numerical studies explored the effect of biofilm properties (thickness, hydraulic permeability and porosity), biofilm membrane surface coverage, and biofilm location on salt external concentration polarization and on the permeation flux. The numerical simulations revealed that (i) when biofouling occurs, external concentration polarization became important, (ii) the biofilm hydraulic permeability and membrane surface coverage have the highest impact on water flux, and (iii) the biofilm formed in the draw channel impacts the process performance more than when formed in the feed channel. The proposed mathematical model helps to understand the impact of biofouling in FO membrane systems and to develop possible strategies to reduce and control biofouling. PMID- 27697689 TI - Biogas production from hydrothermal liquefaction wastewater (HTLWW): Focusing on the microbial communities as revealed by high-throughput sequencing of full length 16S rRNA genes. AB - Hydrothermal liquefaction (HTL) is an emerging and promising technology for the conversion of wet biomass into bio-crude, however, little attention has been paid to the utilization of hydrothermal liquefaction wastewater (HTLWW) with high concentration of organics. The present study investigated biogas production from wastewater obtained from HTL of straw for bio-crude production, with focuses on the analysis of the microbial communities and characterization of the organics. Batch experiments showed the methane yield of HTLWW (R-HTLWW) was 184 mL/g COD, while HTLWW after petroleum ether extraction (PE-HTLWW), to extract additional bio-crude, had higher methane yield (235 mL/g COD) due to the extraction of recalcitrant organic compounds. Sequential batch experiments further demonstrated the higher methane yield of PE-HTLWW. LC-TOF-MS, HPLC and gel filtration chromatography showed organics with molecular weight (MW) < 1000 were well degraded. Results from the high-throughput sequencing of full-length 16S rRNA genes analysis showed similar microbial community compositions were obtained for the reactors fed with either R-HTLWW or PE-HTLWW. The degradation of fatty acids were related with Mesotoga infera, Syntrophomonas wolfei et al. by species level identification. However, the species related to the degradation of other compounds (e.g. phenols) were not found, which could be due to the presence of uncharacterized microorganisms. It was also found previously proposed criteria (97% and 98.65% similarity) for species identification of 16S rRNA genes were not suitable for a fraction of 16S rRNA genes. PMID- 27697690 TI - New oral cut-off time limits in NSW. AB - Standard collection procedure for the investigation of allegations of penile - oral assault has traditionally been the oral swab. Review of both the literature and NSW forensic laboratory results from oral swabbing has highlighted the sub optimal nature of this method for the recovery of both sperm and offender DNA. 554 oral swabs, collected in NSW from 2010 to 2015, were analysed. Sperm detection occurred in only 4.2%. In the same period there was analysis of 104 oral rinses (of which 16.4% were positive for sperm) and 71 peri-oral samples (of which 18.3% were positive for sperm). As a result, a decision was made to revise forensic collection guidelines for sample collection in cases of penile - oral assault. Oral swabbing is no longer recommended. Current NSW forensic collection guidelines recommend the collection of both an oral rinse and a peri-oral (lip) swab. Samples are to be taken in the first 12 h after a penile - oral assault in all cases where there is a suspicion of oral assault. Oral collections may be extended to 24 h post penile - oral assault in those cases where there is either a clear recollection of ejaculation into the mouth (or ejaculation elsewhere prior to penile penetration of the mouth) or in those cases where a complainant is clear that there had been penile penetration of the mouth but is unable to recall whether or not ejaculation has taken place. PMID- 27697691 TI - Reliability of physical examination tests for the diagnosis of knee disorders: Evidence from a systematic review. AB - Clinicians often rely on physical examination tests to guide them in the diagnostic process of knee disorders. However, reliability of these tests is often overlooked and may influence the consistency of results and overall diagnostic validity. Therefore, the objective of this study was to systematically review evidence on the reliability of physical examination tests for the diagnosis of knee disorders. A structured literature search was conducted in databases up to January 2016. Included studies needed to report reliability measures of at least one physical test for any knee disorder. Methodological quality was evaluated using the QAREL checklist. A qualitative synthesis of the evidence was performed. Thirty-three studies were included with a mean QAREL score of 5.5 +/- 0.5. Based on low to moderate quality evidence, the Thessaly test for meniscal injuries reached moderate inter-rater reliability (k = 0.54). Based on moderate to excellent quality evidence, the Lachman for anterior cruciate ligament injuries reached moderate to excellent inter-rater reliability (k = 0.42 to 0.81). Based on low to moderate quality evidence, the Tibiofemoral Crepitus, Joint Line and Patellofemoral Pain/Tenderness, Bony Enlargement and Joint Pain on Movement tests for knee osteoarthritis reached fair to excellent inter-rater reliability (k = 0.29 to 0.93). Based on low to moderate quality evidence, the Lateral Glide, Lateral Tilt, Lateral Pull and Quality of Movement tests for patellofemoral pain reached moderate to good inter-rater reliability (k = 0.49 to 0.73). Many physical tests appear to reach good inter-rater reliability, but this is based on low-quality and conflicting evidence. High quality research is required to evaluate the reliability of knee physical examination tests. PMID- 27697692 TI - Treponema denticola, Porphyromonas gingivalis, and Tannerella forsythia induce cell death and release of endogenous danger signals. AB - OBJECTIVE: The aim of this study was to analyze whether periodontopathogens induced inflammatory cell death and the release of diverse endogenous danger molecules in THP-1-derived macrophages. METHODS: The macrophages were treated with Treponema denticola, Porphyromonas gingivalis, and Tannerella forsythia. Activation of caspase-1 and caspase-4 was detected by Western blotting. Cell death of bacteria-stimulated macrophages was examined using a lactate dehydrogenase (LDH) assay and propidium iodide (PI)/annexin V (AV) staining. Levels of endogenous danger signals, including adenosine triphosphate (ATP), uric acid, heat shock protein 60 (HSP60), high-mobility group box protein 1 (HMGB1), and fibronectin in the culture supernatants were determined using an ATP bioluminescence assay kit, a uric acid assay kit, and Western blotting, respectively. RESULTS: T. denticola, P. gingivalis, and T. forsythia induced activation of caspase-1 and caspase-4. The LDH assay and PI/AV staining showed that all three pathogens induced pyroptotic cell death. All three bacteria induced release of ATP, which is an important ligand for inflammasome activation; the increase in ATP ultimately leads to caspase-1 activation. T. denticola induced release of HSP60 and fibronectin, while T. forsythia induced release of HMGB1 in addition to HSP60 and fibronectin. None of the endogenous molecules except for fibronectin were detected in P. gingivalis-infected cells, possibly due to degradation of these factors by the proteolytic activity of the bacteria. Interestingly, P. gingivalis induced uric acid release. CONCLUSION: Inflammatory cell death and endogenous danger molecules released from cells infected with periodontopathogens may play critical roles in the pathogenesis and progression of periodontitis by augmenting immune and inflammatory responses. PMID- 27697693 TI - Changes in the oral ecosystem induced by the use of 8% arginine toothpaste. AB - OBJECTIVE: Bacterial metabolism of arginine in the oral cavity has a pH-raising and thus, potential anti-caries effect. However, the influence of arginine on the oral microbial ecosystem remains largely unresolved. DESIGN: In this pilot study, nine healthy individuals used toothpaste containing 8% arginine for eight weeks. Saliva was collected to determine arginolytic potential and sucrose metabolic activity at the Baseline, Week 4, Week 8 and after a two weeks Wash-out period. To follow the effects on microbial ecology, 16S rDNA sequencing on saliva and plaque samples at Baseline and Week 8 and metagenome sequencing on selected saliva samples of the same time-points was performed. RESULTS: During the study period, the arginolytic potential of saliva increased, while the sucrose metabolism in saliva decreased. These effects were reversed during the Wash-out period. Although a few operational taxonomic units (OTUs) in plaque changed in abundance during the study period, there was no real shift in the plaque microbiome. In the saliva microbiome there was a significant compositional shift, specifically the genus Veillonella had increased significantly in abundance at Week 8. CONCLUSION: Indeed, the presence of arginine in toothpaste affects the arginolytic capacity of saliva and reduces its sucrose metabolic activity. Additionally, it leads to a shift in the salivary microbiome composition towards a healthy ecology from a caries point of view. Therefore, arginine can be regarded as a genuine oral prebiotic. PMID- 27697695 TI - Radical treatment of extensive nevoid hyperkeratosis of the areola and breast with surgical excision after mild response to topical agents: A case report. AB - INTRODUCTION: Nevoid hyperkeratosis of the nipple and/or areola (NHNA) is a benign lesion with a female predominance and an aesthetically disturbing appearance. Spontaneous remission is not reported and medical treatments proposed so far have shown variable results. PRESENTATION OF CASE: We describe a rare case of an extensive variant of NHNA covering almost the entire breasts' surface. At present, only three other reports are present in the literature. Medical treatment proved not completely effective and the patient was also affected by a significant breast asymmetry-hypertrophy. Therefore, NHNA was managed surgically with excision of the areolar affected portions while performing breast reduction lift. The result was satisfactory and without recurrence of lesions at 5-year follow-up. DISCUSSION: This case reported favorable outcomes of surgery for NHNA. Reports of success with these procedures are still limited, but the promising results in terms of radicality and aesthetic outcome suggest it should be offered to patients as a viable therapeutic option. CONCLUSION: Indications for surgical treatment of NHNA can be: unsatisfying response to topical agents; young patients who want to restore the aesthetic appearance of the breast; and patients with concomitant indication for corrective surgery of the breast. Advantages are: predictable time of healing; predictable final result; radical excision of the affected tissue; and possibility of histologic analysis of the whole areola. In rare cases of lesions extending to the breast, preliminary treatment with topical agents can limit the extent of excision. Management and treatment should always be tailor-made for each individual case. PMID- 27697696 TI - Basal cell carcinoma mimicking pilonidal sinus: A case report with literature review. AB - INTRODUCTION: Pilonidal sinus is a common benign disease that accounts for almost 15% of anal suppurations while basal cell carcinoma is the most common malignancy of the sun-exposed area occurring mainly on the head and neck. We report a case of basal cell carcinoma presented with signs and symptoms of PNS. A 40-year-old male presented with swelling of the lower back for 2 years. On examination, there was a round, mobile, soft 4*2.5cm mass on the sacrococcygeal area. Ultrasound showed subcutaneous cystic lesion. Clinical diagnosis of PNS was done and excisional biopsy was performed under local anesthesia. The result of the histopathological examination was suggestive for basal cell carcinoma. CONCLUSION: Basal cell carcinoma should not be forgotten in differential diagnosis of superficial mass and abscesses. PMID- 27697694 TI - Regional expression of the MAPT gene is associated with loss of hubs in brain networks and cognitive impairment in Parkinson disease and progressive supranuclear palsy. AB - Abnormalities of tau protein are central to the pathogenesis of progressive supranuclear palsy, whereas haplotype variation of the tau gene MAPT influences the risk of Parkinson disease and Parkinson's disease dementia. We assessed whether regional MAPT expression might be associated with selective vulnerability of global brain networks to neurodegenerative pathology. Using task-free functional magnetic resonance imaging in progressive supranuclear palsy, Parkinson disease, and healthy subjects (n = 128), we examined functional brain networks and measured the connection strength between 471 gray matter regions. We obtained MAPT and SNCA microarray expression data in healthy subjects from the Allen brain atlas. Regional connectivity varied according to the normal expression of MAPT. The regional expression of MAPT correlated with the proportionate loss of regional connectivity in Parkinson's disease. Executive cognition was impaired in proportion to the loss of hub connectivity. These effects were not seen with SNCA, suggesting that alpha-synuclein pathology is not mediated through global network properties. The results establish a link between regional MAPT expression and selective vulnerability of functional brain networks to neurodegeneration.

PMID- 27697699 TI - The effect of narrow provider networks on health care use. AB - Network design is an often overlooked aspect of health insurance contracts. Recent policy factors have resulted in narrower provider networks. We provide plausibly causal evidence on the effect of narrow network plans offered by a large national health insurance carrier in a major metropolitan market. Our econometric design exploits the fact that some firms offer a narrow network plan to their employees and some do not. Our results show that narrow network health plans lead to reductions in health care utilization and spending. We find evidence that narrow networks save money by selecting lower cost providers into the network. PMID- 27697698 TI - Characterization of brevetoxin (PbTx-3) exposure in neurons of the anoxia tolerant freshwater turtle (Trachemys scripta). AB - Harmful algal blooms are increasing in frequency and extent worldwide and occur nearly annually off the west coast of Florida where they affect both humans and wildlife. The dinoflagellate Karenia brevis is a key organism in Florida red tides that produces a suite of potent neurotoxins collectively referred to as the brevetoxins (PbTx). Brevetoxins bind to and open voltage gated sodium channels (VGSC), increasing cell permeability in excitable cells and depolarizing nerve and muscle tissue. Exposed animals may thus show muscular and neurological symptoms including head bobbing, muscle twitching, paralysis, and coma; large HABs can result in significant morbidity and mortality of marine life, including fish, birds, marine mammals, and sea turtles. Brevetoxicosis however is difficult to treat in endangered sea turtles as the physiological impacts have not been investigated and the magnitude and duration of brevetoxin exposure are generally unknown. In this study we used the freshwater turtle Trachemys scripta as a model organism to investigate the effects of the specific brevetoxin PbTx-3 in the turtle brain. Primary turtle neuronal cell cultures were exposed to a range of PbTx-3 concentrations to determine excitotoxicity. Agonists and antagonists of voltage-gated sodium channels and downstream targets were utilized to confirm the toxin's mode of action. We found that turtle neurons are highly resistant to PbTx 3; while cell viability decreased in a dose dependent manner across PbTx-3 concentrations of 100-2000nM, the EC50 was significantly higher than has been reported in mammalian neurons. PbTx-3 exposure resulted in significant Ca2+ influx, which could be fully abrogated by the VGSC antagonist tetrodotoxin, NMDA receptor blocker MK-801, and tetanus toxin, indicating that the mode of action in turtle neurons is the same as in mammalian cells. As both turtle and mammalian VGSCs have a high affinity for PbTx-3, we suggest that the high resistance of the turtle neuron to PbTx-3 may be related to its ability to withstand anoxic depolarization. The ultimate goal of this work is to design treatment protocols for sea turtles exposed to red tides worldwide. PMID- 27697700 TI - Mechanistic insights into Diels-Alder reactions in natural product biosynthesis. AB - Natural enzymes that catalyze Diels-Alder reactions have long been sought after, yet few enzymes have been experimentally confirmed to perform this reaction. In the past five years, several stand-alone enzymes that can catalyze the Diels Alder reaction had been identified and characterized. Among which, the crystal structures of SpnF, PyrI4 and AbyU have been determined. The structures of PyrI4 and AbyU, which are involved in spirotetronate/spirotetramate biosynthesis, are particularly informative since they shed light on how a natural catalyst captures the flexible substrate and facilitates the intramolecular Diels-Alder reaction through stabilization of the transition state in catalysis. These pioneering studies will inspire the design of artificial catalysts for Diels-Alder reactions. PMID- 27697701 TI - Non-natural carbenoid and nitrenoid insertion reactions catalyzed by heme proteins. AB - Despite increasing interest in using enzymes as tools for synthesis, many reactions discovered through the creativity of synthetic chemists remain beyond the scope of biocatalysis. This vacancy in the field has compelled researchers to develop strategies to adapt protein scaffolds for new reactivity. Heme proteins have recently been shown to activate synthetic precursors to generate reactive metallocarbenoid and metallonitrenoid species that enable the biosynthetic construction of novel C-C, C-N, and other bonds using mechanisms not previously explored by Nature. By interrogating heme proteins with synthetic, non-natural reagents, scientists are merging the reaction space traditionally dominated by organocatalysis and transition metal catalysis with the mild reaction conditions, selectivity, and adaptability imparted by native protein scaffolds. PMID- 27697702 TI - Abnormal regulation of the antiviral response in neurological/neurodegenerative diseases. AB - Alzheimer's disease, Parkinson's disease, multiple sclerosis, and amyotrophic lateral sclerosis are a few examples of debilitating neurological/neurodegenerative diseases for which there are currently no curative treatments. Recent evidence has strongly suggested a role for neuroinflammation in both the onset and progression of these diseases. However, the mechanisms that initiate neuroinflammation are presently unclear. Mounting evidence suggests that environmental factors are likely involved. One proposed mechanism linking both genetic and environmental factors is dysregulation of the antiviral response. Indeed, many mutations that have been linked to neurological conditions occur in genes related to the antiviral response. Although the products of these genes may have potent antiviral activities - they can also have deleterious effects when their expression is not appropriately regulated. For that reason, expression of antiviral genes is a tightly controlled process. Herein, we review the various antiviral genes that have been linked to neurological conditions. We focus specifically on type I interferonopathies, the symptoms of which are often evident at birth, and neurodegenerative diseases, which frequently onset later in life. PMID- 27697703 TI - Dynamics of cytokine mRNA expression and fecal biomarkers in school-children undergoing a double-blind placebo-controlled food challenge series. AB - BACKGROUND: There is need for prognostic markers for symptomatic food allergy since current diagnostic methods are insufficient and/or time and labor consuming. OBJECTIVE: To estimate the cytokine mRNA profiles in peripheral blood mononuclear cells (PBMC) before and after a double-blind placebo-controlled food challenge series in schoolchildren with suspected allergy to milk, egg or cod and in healthy controls. Analyses of fecal inflammatory biomarkers before and after the challenge were included. METHODS: Twelve-year-old children from a population based cohort reporting complete avoidance of milk, egg, cod or wheat due to perceived hypersensitivity were clinically examined and those with suspected food allergy were evaluated with a 3-session double-blind placebo-controlled food challenge (n=18). Seven healthy controls participated in a double-blind challenge with egg. Before and after the challenge series, the cytokine mRNA expression was quantified for 13 cytokines discriminating between humoral Th2-, cytotoxic Th1-, regulatory Th3/Tr1- and inflammatory responses. Fecal calprotectin and eosinophil derived neurotoxin (EDN) were also analyzed in children with suspected food allergy before and after the challenge series. RESULTS: Pre challenge, children with suspected food allergy had higher IL-13andTNF-alpha expression and lower IFN gamma and IL-15 expression compared to healthy controls (all p<0.05). Children with challenge-proven food allergy had increased IL13andIL-10 expression compared to the levels seen in negative challenges (p<0.05). Post challenge, IL-1beta and IL-6 mRNA levels were elevated in the food allergic children compared to controls (p<0.05). Fecal calprotectin and EDN levels were higher in challenge-proven food allergy compared to a negative challenge although not statistically significantly. CONCLUSION & CLINICAL RELEVANCE: Increased baseline mRNA levels of the Th2-related cytokine IL-13 and the regulatory cytokine IL-10 predicted a positive food challenge outcome. These cytokines in combination with fecal calprotectin and EDN might serve as future prognostic markers for symptomatic, IgE-mediated food allergy but need further validation in a larger patient cohort. PMID- 27697704 TI - Mercury and selenium in the food web of Lake Nahuel Huapi, Patagonia, Argentina. AB - Despite located far from point sources of Hg pollution, high concentrations were recorded in plankton from the deep oligotrophic Lake Nahuel Huapi, located in North Patagonia. Native and introduced top predator fish with differing feeding habits are a valuable economic resource to the region. Hence, Hg and Se trophic interactions and pathways to these fish were assessed in the food web of this lake at three sites, using stable nitrogen and carbon isotopes. As expected based on the high THg in plankton, mercury did not biomagnify in the food web of Lake Nahuel Huapi, as most of the THg in plankton is in the inorganic form. As was observed in other aquatic systems, Se did not biomagnify either. When trophic pathways to top predator fish were analyzed, they showed that THg biomagnified in the food chains of native fish but biodiluted in the food chains of introduced salmonids. A more benthic diet, typical of native fish, resulted in higher [THg] bioaccumulation than a more pelagic or mixed diet, as in the case of introduced fish. Se:THg molar ratios were higher than 1 in all the fish species, indicating that Se might be offering a natural protection against Hg toxicity. PMID- 27697706 TI - Electro-oxidation and characterization of nickel foam electrode for removing boron. AB - The electrocoagulation (EC) using metallic Ni foam as electrodes was studied for the removal of boron from solution. The electrolytic parameters were pH (4-12), current density (0.6-2.5 mA cm-2), and initial concentration of boron (10-100 mg L-1). Experimental results revealed that removal efficiency was maximized at pH 8 9, and decreased as the pH increased beyond that range. At particular onset potentials (0.5-0.8 V vs. Hg/HgO), the micro-granular nickel oxide that was created on the surface of the nickel metal substrate depended on pH, as determined by cyclic voltammetry. Most of the crystallites of the precipitates comprised a mixed phase of beta-Ni(OH)2, a theophrastite phase, and NiOOH, as revealed by XRD and SEM analyses. A current density of 1.25 mA cm-2 was effective in the EC of boron, and increasing the concentration of boric acid from 10 to 100 mg L-1 did not greatly impair removal efficiency. A kinetic investigation revealed that the reaction followed a pseudo-second order rate model. The optimal conditions under which 99.2% of boron was removed from treated wastewater with 10 mg L-1-B, leaving less than 0.1 mg L-1-B in the electrolyte, were pH 8 and 1.25 mA cm-2 for 120 min. PMID- 27697705 TI - Pentachlorophenol affected both reproductive and interrenal systems: In silico and in vivo evidence. AB - The present study investigated the effects on reproductive and interrenal system by pentachlorophenol (PCP) using in silico and in vivo assays. Molecular docking results indicated interacting potency of PCP with steroid receptors (ERalpha, ERbeta, AR, GR) but not Cytochrome P450 enzymes (CYPs). In the in vivo assay, sexually matured rare minnow (Gobiocypris rarus) was exposed to environmental relevant concentrations of PCP (0, 0.5, 5, 50 MUg L-1). In male fish, 14-d exposure caused up-regulation of mRNA levels of hepatic eralpha, erbeta, ar, gr, vtg and gonadal eralpha, vtg, ar, dmrt1, providing evidence for agonistic activities for steroid receptors by PCP. The up-regulated mRNA of gnrh, crf, pomc in the brain also indicated feed-forward responses of the hypothalamic-pituitary gonadal/interrenal (HPG/I) axis. However, at 28th d the feed-forward response of the HPG axis seemed eased back and the HPI axis showed negative feedback responses. Corresponding changes including increases of plasma steroid hormones, inhibition of spermatogenesis, and decreased RSI were observed in male fish upon 28-d exposure to PCP. In the females, a transition from feed-forward responses to negative feedbacks of the HPG/I axis was also indicated by the transcriptional profiles at 14th and 28th day. Corresponding changes including increased E2, T and decreased C levels, degenerated ovaries, and decreased GSI and RSI were also observed. Overall, we concluded that PCP could interfere with steroid receptors, evoke responses of HPG/I axis, and finally result in adverse effects on reproductive and interrenal system in rare minnow at environmental relevant concentrations. PMID- 27697707 TI - Exploring the ability of cations to facilitate binding between inorganic oxyanions and humic acid. AB - The mobility and fate of inorganic oxyanions in the environment can be greatly influenced by interactions with natural organic matter (NOM). There is increasing evidence that this interaction between two anionic species is facilitated by cationic bridges, but detailed mechanistic studies into this system are challenging due to the heterogeneous nature of NOM. This work examines the ability of cations (FeIII, CrIII, AlIII, or GaIII) to form ternary complexes with Suwannee River humic acid (SRHA) and the oxyanions of As (AsIII and AsV) and Se (SeIV and SeVI). Complexes were characterized by separating SRHA from unbound species using size exclusion chromatography coupled to ICP-MS to determine its metal content. Unlike CrIII and FeIII, the post-transition metal ions AlIII and GaIII proved ineffective at forming ternary complexes with any of the oxyanions, although minor complexation was observed with GaIII, suggesting that electrostatic interactions are not the primary driving force behind the stabilization of these ternary complexes. The results also show differences in the behavior of FeIII and CrIII that may indicate that the two cations stabilize the ternary complexes by different mechanisms. PMID- 27697708 TI - Chemical removal of nitrate from water by aluminum-iron alloys. AB - Zero-valent iron has been intensively investigated in chemical reduction of nitrate in water, but the reduction requires acidic or weak acidic pH conditions and the product of the reduction is exclusively ammonium, an even more toxic substance. Zero-valent aluminum is a stronger reductant than iron, but its use for the reduction of aqueous nitrate requires considerably alkaline pH conditions. In this study, aluminum-iron alloys with an iron content of 10%, 20% and 58% (termed Al-Fe10, Al-Fe20 and Al-Fe58, respectively) were investigated for the reduction of aqueous nitrate. Al-Fe alloys were efficient to reduce nitrate in water in an entire pH range of 2-12 and the reduction proceeded in a pseudo first order at near neutral pH conditions. The observed reaction rate constant (Kobs) of Al-Fe10 was 3 times higher than that of Fe and the Kobs of Al-Fe20 doubled that of Al-Fe10. The nitrogen selectivity of the reduction by Al-Fe10, Al Fe20 and Al-Fe58 was 17.6%, 23.9% and 40.3%, respectively at pH 7 and the nitrogen selectivity by Al-Fe20 increased from 18.9% at pH 2-60.3% at pH 12. The enhanced selectivity and reactivity of Al-Fe alloys were likely due to the presence of an intermetallic Al-Fe compound (Al13Fe4). PMID- 27697710 TI - Immunotoxic effects of atrazine and its main metabolites at environmental relevant concentrations on larval zebrafish (Danio rerio). AB - Atrazine (ATZ) and its main metabolites, i.e., diaminochlorotriazine (DACT), deisopropylatrazine (DIP), and deethylatrazine (DE), have been widely detected in surface water around the world. In the present study, to determine their immunotoxic effects, zebrafish during the early developmental stage were exposed to ATZ and its main metabolites at environmental concentrations (30, 100, 300 MUg L-1). It was observed that ATZ, DACT, DIP and DE selectively induced the transcription of immunotoxic related genes including Tnfalpha, Il-1beta, Il-6, Il 8, Cxcl-clc and Cc-chem in larval zebrafish. Pretreatment with ATZ and its metabolites also changed the immune response of larval zebrafish to LPS and E. coli challenge, which was indicated by the alternation in the mRNA levels of some cytokines. In addition, 300 MUg L-1 ATZ and DACT exposure could also increase the release of tryptase into water, indicating that they increased the anaphylactoid reaction in the larval zebrafish. According to these results, both of ATZ and its metabolites exposure could cause the immunotoxicity in larval zebrafish. Thus, we thought that the ecological risks of the metabolites of ATZ on aquatic organisms could not be ignored.

AB - In this study, the characterizations and adsorption efficiencies for chromium, copper and nickel were evaluated using manufacture-grade Fe2O3-carbon foam. SEM, XRD, XRF and BET analyses were performed to determine the characteristics of the material. Various pore sizes (12-420 MUm) and iron contents (3.62%) were found on the surface of the Fe2O3-carbon foam. Fe2O3-carbon foam was found to have excellent adsorption efficiency compared to carbon foam for mixed solutions of cationic and anionic heavy metals. The adsorption capacities for chromium, copper and nickel were 6.7, 3.8 and 6.4 mg/g, respectively, which were obtained using a dual exponential adsorption model. In experiments with varying dosages of the Fe2O3 powder, no notable differences were observed in the removal efficiency. In a fixed-bed column test, Fe2O3-carbon foam achieved adsorption capacities for chromium, copper and nickel of 33.0, 12.0 and 9.5 mg/g, respectively, after 104 h. Based on these results, Fe2O3-carbon foam was observed to be a promising material for treatment of plating wastewater.

AB - Sphingolipids are the main components of the lipid membrane. They also perform structural functions and participate in many signal transmission processes. One of the bioactive sphingolipids is sphingosine-1-phosphate (S1P), a ligand for five G protein-coupled receptors (S1PRs1-5), which can also act as an intracellular second messenger. S1P is responsible for the stimulation of progenitor cells in the brain, but it can also induce apoptosis of mature neurons. This study is aimed at assessing the effect of pre- and neonatal exposure to permissible Pb concentrations on S1P levels and S1PR1 (EDG1) expression in the prefrontal cortex, cerebellum, and hippocampus of rats. The concentrations of S1P were determined by RP-HPLC, S1PR1 expression was determined by RT PCR and Western Blot, and receptor immunolocalization was determined by immunohistochemistry method. Our results showed that even low blood Pb concentrations, i.e. within the acceptable limit of 10 MUg/dL caused changes in the concentration of S1P in the cerebellum, prefrontal cortex, and hippocampus. Our data also showed a significant decrease in the level of S1PR1 in all studied part of brain, without significant changes in S1PR1 gene expression. Pre- and neonatal exposure to Pb also resulted in a decrease in the expression of S1PR1 in glial cells in all regions of the Cornu Ammonis (CA1-CA4) and Dentate Gyrus in the hippocampus, as well as in all layers of the cerebellum and prefrontal cortex, compared to the unexposed control group.

AB - In this work, it has been studied the mineralization of aniline, a toxic substance of low biodegradability typically found in many industrial wastewaters, through electro-oxidation using boron doped diamond (BDD) electrodes and photo oxidation (UV photolysis and UV/H2O2 treatments). It was observed that in electro oxidation and UV/H2O2, it was feasible to reach aniline mineralizations higher than 85%. Two different degradation routes have been observed during the aniline oxidation in these two treatments. The first route was the mineralization pathway, in which aniline was oxidized to CO2, water and nitrate. The second route was the polyaniline pathway in which polyanilines of high molecular weight are formed. The intermediate compounds involved in both degradation routes are different depending on the treatment used. In the electro-oxidation, denitrification processes were also observed. From an economical point of view, electro-oxidation of aniline using BDD electrodes is more interesting than UV/H2O2 due it has an 87% lower operational cost. So, electro-oxidation using BDD electrodes seems to be a more suitable technique for the mineralization of wastewater containing aniline than UV or H2O2 based technologies.

AB - Arsenic, a naturally occurring heavy metal pollutant, is one of the functioning risk factors for neurological toxicity in humans. However, little is known about the effects of arsenic on the nervous system of Gallus Gallus. To investigate whether arsenic induce neurotoxicity and influence the oxidative stress and heat shock proteins (Hsps) response in chickens, seventy-two 1-day-old male Hy-line chickens were treated with different doses of arsenic trioxide (As2O3). The histological changes, antioxidant enzyme activity, and the expressions of Hsps were detected. Results showed slightly histology changes were obvious in the brain tissues exposure to arsenic. The activities of Glutathione peroxidase (GSH Px) and catalase (CAT) were decreased compared to the control, whereas the malondialdehyde (MDA) content was increased gradually along with increase in diet arsenic. The mRNA levels of Hsps and protein expressions of Hsp60 and Hsp70 were up-regulated. These results suggested that sub-chronic exposure to arsenic induced neurotoxicity in chickens. Arsenic exposure disturbed the balance of oxidants and antioxidants. Increased heat shock response tried to protect chicken brain tissues from tissues damage caused by oxidative stress. The mechanisms of neurotoxicity induced by arsenic include oxidative stress and heat shock protein response in chicken brain tissues. PMID- 27697714 TI - Relationships between serum BDNF and the antidepressant effect of acute exercise in depressed women. AB - OBJECTIVE: Brain-derived neurotrophic factor (BDNF) has recently emerged as one potential mechanism with which exercise improves mood in major depressive disorder (MDD). This study examined the relationship between changes in serum total BDNF and mood following acute exercise in MDD. It was hypothesized that acute exercise would increase BDNF in an intensity-dependent manner and that changes in BDNF would be significantly related to improvement in depressed mood post-exercise. METHODS: Twenty-four women (age: 38.6+/-14.0years) with MDD exercised for 30min on a stationary bicycle at light, moderate and hard exercise intensities and performed a quiet rest session using a within-subjects, randomized and counter-balanced design. Before, 10 and 30min after each session, participants completed the profile of mood states (POMS). Blood was drawn before and within 10min after completion of each session and serum total BDNF (sBDNF) was measured by enzyme-linked immunosorbent assay. Acute exercise-induced changes in POMS Depression and sBDNF were analyzed via 4 session (quiet rest, light, moderate, hard) by 2 measurement (pre, post) ANOVA. Secondary analyses examined the effects of baseline mood and antidepressant usage on sBDNF. RESULTS: Exercise resulted in an acute improvement in depressed mood that was not intensity dependent (p>0.05), resulting in significant acute increases in sBDNF (p=0.006) that were also not intensity-dependent (p>0.05). Acute changes in sBDNF were not significantly correlated to changes in POMS depression at 10m (r=-0.171, p=0.161) or 30m (r=-0.151, p=0.215) post-exercise. The fourteen participants taking antidepressant medications exhibited lower post-exercise sBDNF (p=0.015) than the participants not currently taking antidepressants, although mood responses were similar. CONCLUSION: Acute exercise is an effective mood-enhancing stimulus, although sBDNF does not appear to play a role in this short-term response. Patients who are not currently taking antidepressant medications and those who have greater pre-exercise depression may experience a greater sBDNF response to exercise, but the clinical significance of this is currently unclear. Circulating BDNF levels are unlikely to be altered by steady-state acute exercise in a linear dose-dependent manner. This does not eliminate its potential relevance in the antidepressant response to chronic exercise training, but suggests that other mechanisms are involved in the acute affective response to exercise in depression. PMID- 27697715 TI - Swelling of glucose-responsive gels functionalized with boronic acid. AB - A model is developed for the elastic response of a glucose-sensitive gel functionalized with boronic acid under swelling in aqueous solutions of glucose with various pH. A gel is treated as a three-phase medium composed of a solid phase (partially ionized polymer network), solvent (water), and solute (mobile glucose molecules and ions). Constitutive equations are derived by means of the free energy imbalance inequality for three-dimensional deformation with finite strains. Numerical analysis demonstrates the ability of the model to describe the effects of pH, molar fraction of glucose, and concentration of functional groups on equilibrium water uptake diagrams under unconstrained and constrained swelling. PMID- 27697716 TI - Effect of an amorphous titania nanotubes coating on the fatigue and corrosion behaviors of the biomedical Ti-6Al-4V and Ti-6Al-7Nb alloys. AB - An array of self-organized TiO2 nanotubes with an amorphous structure was produced on the biomedical Ti-6Al-4V and Ti-6Al-7Nb alloys, and the resulting fatigue and corrosion behaviors were studied. The electrochemical response of the nanotubular oxide surfaces was investigated in Ringer physiological solution through potentiodynamic polarization and electrochemical impedance spectroscopy measurements. The absence of transpassivation in the chloride-containing solution, in addition to the micron-scale values of the passivation current density, indicated the excellent corrosion behavior of the coating and the satisfactory protection against the creation of potential stress concentrators in the surface. Axial fatigue tests were performed in physiological solution on polished and coated conditions, with characterization of the treated surfaces by scanning electron microscopy before and after the tests. The surface modification was not deleterious to the fatigue response of both alloys mainly due to the nano scale dimension of the nanotubes layer. An estimation based on fracture mechanics revealed that a circumferential crack in the range of 5MUm depth would be necessary to affect the fatigue performance, which is far from the thickness of the studied coating, although no cracks were actually observed in the oxide surfaces after the tests. PMID- 27697717 TI - Gel-spinning of mimetic collagen and collagen/nano-carbon fibers: Understanding multi-scale influences on molecular ordering and fibril alignment. AB - Synthetic gel-spun collagen and collagen/nano-carbon fibers were found to exhibit structural mimicry comparable to native tendons. X-ray scattering and microscopy analyses are used to characterize the molecular and fibrillar alignment in the synthetic fibers, where D-banding is observed throughout the spun fibers - consistent with native collagen. For the composite collagen/nano-carbon fibers, the morphology and dispersion quality of the nano-carbons within was found to play a significant role in influencing collagen molecular ordering and fibril alignment. Fibrillar and molecular alignment was also better preserved during elongation of the composites as compared to the control collagen fibers. These results show the structural influence of a rigid inclusion on the collagen fibril structure. Both dry- and wet-state tensile testing were performed on the collagen fibers, and these results show behavior comparable to the native materials. Dry state tests also reveal interfacial interaction between the nano-fillers and the collagen fibrils through theoretical analysis. Wet-state tensile testing indicates the structure-property behavior of the mimetic hierarchical structure within the synthetic fibers. PMID- 27697718 TI - Outcome of temporal lobe epilepsy surgery evaluated with bitemporal intracranial electrode recordings. AB - BACKGROUND: Temporal lobe epilepsy (TLE) with unclear lateralization may require intracranial implantation of electrodes (IIE). We retrospectively assessed the association between the use of IIE and long-term outcomes in patients undergoing anterior temporal lobectomy (ATL). PARTICIPANTS AND METHODS: We retrospectively reviewed the records of 1,032 patients undergoing epilepsy surgery at our center from 1977 to 2006. Patients who underwent ATL were included. Seizure outcome was assessed through final follow-up. Those who underwent scalp and IIE (mostly evaluated with temporal subdural strip electrodes) were compared. RESULTS: From 497 patients who underwent ATL, 139 did so after IIE placement in the temporal lobes. Mean age at surgery was 32.3+/-12.3years and median duration of follow-up 24 months (range: 6-36). Fifty-three percent of those evaluated with IIE were seizure-free at their last available visit (vs. 68% evaluated with only scalp EEG, p=0.002). Patients with lesional TLE generally had a better outcome (65.5% seizure free) than those without lesions (56.3%, p=0.093), especially for unilateral TLE diagnosed with IIE. In a multivariate Cox regression analyses adjusted for gender, neuropsychological concordance, pathological findings, and post-operative seizures, bilateral TLE predicted seizure recurrence in IIE patients (HR=2.08, 95% CI: 1.08-4.0, p=0.029). CONCLUSIONS: More than a half of those who undergo IIE in suspected TLE are seizure free after ATL. IIE allows for the identification of surgical candidates. PMID- 27697719 TI - Medial-lateral centre of mass displacement and base of support are equally good predictors of metabolic cost in amputee walking. AB - Amputees are known to walk with greater metabolic cost than able-bodied individuals and establishing predictors of metabolic cost from kinematic measures, such as centre of mass (CoM) motion, during walking are important from a rehabilitative perspective, as they can provide quantifiable measures to target during gait rehabilitation in amputees. While it is known that vertical CoM motion poorly predicts metabolic cost, CoM motion in the medial-lateral (ML) and anterior-posterior directions have not been investigated in the context of gait efficiency in the amputee population. Therefore, the aims of this study were to investigate the relationship between CoM motion in all three directions of motion, base of support and walking speed, and the metabolic cost of walking in both able-bodied individuals and different levels of lower limb amputee. 37 individuals were recruited to form groups of controls, unilateral above- and below-knee, and bilateral above-knee amputees respectively. Full-body optical motion and oxygen consumption data were collected during walking at a self selected speed. CoM position was taken as the mass-weighted average of all body segments and compared to each individual's net non-dimensional metabolic cost. Base of support and ML CoM displacement were the strongest correlates to metabolic cost and the positive correlations suggest increased ML CoM displacement or Base of support will reduce walking efficiency. Rehabilitation protocols which indirectly reduce these indicators, rather than vertical CoM displacement will likely show improvements in amputee walking efficiency.

AB - The modulation in the photophysics of a pyrazoline dye 3-naphthyl-1-phenyl-5-(4 carboxyphenyl)-2-pyrazoline (NPCP), when it drifts from bulk water into the nanocages of aqueous cyclodextrin solutions was investigated. The intramolecular charge transfer (ICT) fluorescence band intensity was found to increase with a blue shift in the presence of cyclodextrins. The results from 1H NMR and 1HH COSY NMR spectral analysis clearly points out the position of pyrazoline ring inside the cavity and its role in complexation process. A quantitative assessment of the emission intensity data on Benesi-Hildebrand (B-H) equation along with ESI-MS spectra reveals the probable stoichiometry of NPCP-CD complexes. Molecular docking and molecular dynamics studies were conducted for beta/gamma cyclodextrin associated inclusion complexes of NPCP. The results obtained by computational studies are in good relation with the data obtained through experimental methods and both ascertain the encapsulation of NPCP into cyclodextrins. PMID- 27697721 TI - Characterization and intramolecular bonding patterns of busulfan: Experimental and quantum chemical approach. AB - The investigations of structural conformers, molecular interactions and vibrational characterization of pharmaceutical drug are helpful to understand their behaviour. In the present work, the 2D potential energy surface (PES) scan has been performed on the dihedral angles C6O4S1C5 and C25S22O19C16 to find the stable conformers of busulfan. In order to show the effects of long range interactions, the structures on the global minima of PES scan have been further optimized by B3LYP/6-311++G(d,p) method with and without empirical dispersion functional in Gaussian 09W package. The presence of n->sigma* and sigma->sigma* interactions which lead to stability of the molecule have been predicted by natural bond orbital analysis. The strong and weak hydrogen bonds between the functional groups of busulfan were analyzed using quantum topological atoms in molecules analysis. In order to study the long-range forces, such as van der Waals interactions, steric effect in busulfan, the reduced density gradient as well as isosurface defining these interactions has been plotted using Multiwfn software. The spectroscopic characterization on the solid phase of busulfan has been studied by experimental FT-IR and FT-Raman spectra. From the 13C and 1H NMR spectra, the chemical shifts of individual C and H atoms of busulfan have been predicted. The maximum absorption wavelengths corresponding to the electronic transitions between the highest occupied molecular orbital and the lowest unoccupied molecular orbital of busulfan have been found by UV-vis spectrum.

AB - A field-amplified sample stacking-sweeping micellar electrokinetic chromatography with short-end injection was established for determination of deferasirox (DFX) in plasma. DFX was extracted from plasma and reconstituted with deionized water (lower conductivity solution). Capillary (effective length, 10cm) was filled with background electrolyte (40mM phosphate buffer, pH 4.5, containing 20% methanol). After sample loading from outlet end at 5psi for 15s, separation was carried out by applying high voltage at 15kV for 10min. Sodium dodecyl sulfate (SDS) was used to sweep DFX for enhancing sensitivity. The optimal CE separation conditions were 40mM phosphate buffer at pH 4.5 containing 100mM SDS and 20% methanol. The analysis time was about 3.5min for DFX. The calibration curve of DFX was ranged from 1 to 20MUg/ml. The linearity (r) was more than 0.998. RSD and RE in intra- and inter-day assays were all below 12.14%. The limit of detection (LOD, S/N=3) for DFX was 0.3MUg/ml. The sensitivity enhancement factor between sweeping-FASS MEKC and capillary zone electrophoresis is 3.3. Finally, the method was applied for determination of DFX in beta-thalassemia patients. PMID- 27697723 TI - Anticancer effect of SZC015 on lung cancer cells through ROS-dependent apoptosis and autophagy induction mechanisms in vitro. AB - Oleanolic acid (OA) and its several derivatives possess various pharmacological activities, such as antitumor and anti-inflammation. In present study, anticancer effect of SZC015, an OA derivative, and its underlying mechanisms were investigated. We demonstrated that cell viability was significantly decreased in SZC015-treated lung cancer cells, but has less cytotoxicity in human bronchial epithelial cell line. Further investigation verified that apoptosis and autophagy induction and G0/G1 phase arrest were observed in SZC015-treated H322 cells. Mechanically, the level of Akt, p-Akt, p-IkappaBalpha, and total p65, the p-p65 in the cytoplasm and nucleus were suppressed by SZC015 in H322 cells, respectively. Inhibition of p65 nuclear translocation was also confirmed by immunofluorescence staining. In addition, co-treatment with chloroquine, an autophagy inhibitor, significantly inhibited SZC015-induced autophagy and enhanced SZC015-induced apoptotic cell death. Intracellular ROS was increased in a concentration-dependent manner, which could be prevented by N-Acetyl l Cysteine, an ROS scavenger. Moreover, the level of Akt and procaspase-3 were increased, while the ratio of LC3 II/I was decreased. Taken together, our study demonstrates that the inhibitory effect of SZC015 against H322 cells is mediated by excessive ROS generation that could suppress Akt/NF-kappaB signaling pathway, which thereby leads to apoptotic and autophagic cell death. PMID- 27697724 TI - Suppressive effect of beta,beta-dimethylacryloyl alkannin on activated dendritic cells in psoriasis by the TLR7/8 pathway. AB - beta,beta-dimethylacryloyl alkannin (DMA) is a key component of Lithospermum and possesses good efficacy for treating psoriasis. DMA inhibits activated dendritic cells (DCs), but the mechanism is unknown. Therefore, this study aimed to explore the modulation of the TLR7/8 pathway by DMA in psoriasis-activated DCs. Models of psoriasis-like skin lesions were established using BALB/c mice; 8 mice were treated with DMA (2.5mg/kg). Bone marrow cells were isolated and induced into DCs using R848, a TLR7/8 agonist. Splenic CD11c+ cells were detected by flow cytometry. Skin CD11c+ cells were detected by immunofluorescence. TLR7, TLR8, MYD88, and IRAKM proteins were detected by Western blot. The effects of DMA on surface molecules of DCs were observed by flow cytometry. mRNA expression of inflammatory factors was detected by qRT-PCR. Secreted cytokines were detected by cytometric bead array. Compared with the model group, psoriasis-like skin lesions were alleviated by DMA, the splenic CD11c+ cells were significantly decreased (P<0.01), and CD11c+ cell numbers in skin lesions were decreased (P<0.01). Expression levels of TLR7, MYD88, and IRAKM were significantly decreased (P<0.05). R848-stimulated DCs showed increased expression of I-A/I-E, CD80, and CD86 (P<0.01), increased IL-23 and IL-1beta mRNA and secretion (P<0.05), and increased TLR7, TLR8, MYD88, and IRAKM expression (P<0.01); DMA inhibited all of these effects of the TLR7/8 pathway activation by R848 (P<0.05). In conclusion, DMA could inhibit psoriasis-activated DCs via the TLR7/8 pathway. PMID- 27697725 TI - Effects of beta-tricalcium phosphate particles on primary cultured murine dendritic cells and macrophages. AB - Beta-tricalcium phosphate (beta-TCP) is widely used for bone substitution in clinical practice. Particles of calcium phosphate ceramics including beta-TCP act as an inflammation mediators, which is an unfavorable characteristic for a bone substituent or a prosthetic coating material. It is thought that the stimulatory effect of beta-TCP on the immune system could be utilized as an immunomodulator. Here, in vitro effects of beta-TCP on primary cultured murine dendritic cells (DCs) and macrophages were investigated. beta-TCP particles enhanced expression of costimulatory surface molecules, including CD86, CD80, and CD40 in DCs, CD86 in macrophages, and MHC class II and class I molecules in DCs. DEC205 and CCR7 were up-regulated in beta-TCP-treated DCs. Production of cytokines and chemokines, including CCL2, CCL3, CXCL2, and M-CSF, significantly increased in DCs; CCL2, CCL3, CCL4, CCL5, CXCL2, and IL-11ra were up-regulated in macrophages. The results of the functional assays revealed that beta-TCP caused a prominent reduction in antigen uptake by DCs, and that conditioned medium from DCs treated with beta-TCP facilitated the migration of splenocytes in the transwell migration assay. Thus, beta-TCP induced phenotypical and functional maturation/activation of DCs and macrophages; these stimulating effects may contribute to the observed in vivo effect where beta-TCP induced extensive migration of immune cells. When compared to lipopolysaccharide (LPS), an authentic TLR ligand, the stimulatory effect of beta-TCP on the immune systems is mild to moderate; however, it may have some advantages as a novel immunomodulator. This is the first report on the direct in vitro effects of beta-TCP against bone marrow-derived DCs and macrophages. PMID- 27697727 TI - Development and application of a multi-component LC-MS/MS method for determination of designer benzodiazepines in urine. AB - New psychoactive substances (NPS) have become an increasing drug problem in the past decade. For detection of NPS, new analytical methods have to be developed, and the methods also have to be updated regularly. This study aimed at developing a multi-component LC-MS/MS method for detection and quantification of 11 NPS of the benzodiazepine sub-class ("designer benzodiazepines") in urine specimens. The method involves dilution of urine with internal standard and hydrolysis of any glucuronide conjugated forms. Separation of the compounds was achieved on a BEH Phenyl column, followed by MS/MS detection in positive electrospray mode. Method validation was performed following the EMA guideline. The method was applied to study the occurrence of designer benzodiazepines in Sweden in 2014-2015, by analysis of 390 samples retrieved from a routine drug testing laboratory. In 40% of these samples, selected based on a positive immunoassay benzodiazepine screening but a negative MS confirmation for the standard set of prescription benzodiazepines, intake of designer benzodiazepines was revealed. These results stress the importance of using and updating confirmation methods to include the increasing number of designer benzodiazepines appearing on the NPS market. PMID- 27697726 TI - Prevention of azoxymethane/dextran sodium sulfate-induced mouse colon carcinogenesis by processed Aloe vera gel. AB - The preventive effect of a processed Aloe vera gel (PAG) on colon carcinogenesis was examined using an azoxymethane (AOM)-initiated and dextran sodium sulfate (DSS)-promoted mouse colon carcinogenesis model. Oral administration of PAG (200, or 400mg/kg/day) significantly reduced the multiplicity of colonic adenomas and adenocarcinomas compared with the AOM/DSS only-treated mice. In the mice treated with 400mg/kg of PAG, adenoma and adenocarcinoma development was reduced to 80% and 60%, respectively, compared to 100% in the PAG-untreated AOM/DSS-treated mice. Western blot analysis using colon extracts showed that PAG reduced the activation of nuclear factor kappa B (NF-kappaB), resulting in the inhibition of inducible nitric oxide synthase and cyclooxygenase-2 expression. PAG appeared to inhibit the NF-kappaB activation through the activation of peroxisome proliferator-activated receptor gamma. PAG also inhibited the expression and phosphorylation of signal transducer and activator of transcription 3, which is known to connect inflammation and cancer. In addition, PAG inhibited cell cycle progression-inducing cellular factors, such as extracellular signal-regulated kinases 1/2, cyclin-dependent kinase 4, and cyclin D1. On the other hand, PAG increased the expression of Caudal-related homeobox transcription factor 2, which is known to be a tumor suppressor in colorectal cancer. These findings show that PAG suppresses colitis-related colon carcinogenesis by inhibiting both chronic inflammation and cell cycle progression in the colon. PMID- 27697728 TI - An easy-to-use liquid chromatography assay for the analysis of lamotrigine in rat plasma and brain samples using microextraction by packed sorbent: Application to a pharmacokinetic study. AB - A simple and rapid high-performance liquid chromatography method with diode-array detection (HPLC-DAD) using microextraction by packed sorbent (MEPS) during the sample preparation step was developed and validated to quantify lamotrigine (LTG) in rat plasma and brain samples. MEPS variables such as pH, number of draw-eject cycles, and washing and desorption conditions were optimized. The chromatographic resolution of LTG and chloramphenicol, used as internal standard (IS), was accomplished in less than 5min on a C18 column, at 35 degrees C, using an isocratic elution with acetonitrile (13%), methanol (13%) and water-triethylamine (99.7:0.3, v/v; pH 6.0) pumped at a flow rate of 1mL/min. Detection was performed at 215nm. Calibration curves were linear over the range of 0.1-20MUg/mL (r2>=0.9947) for LTG in both rat plasma and brain homogenate samples. The intra and interday imprecision did not exceed 8.6% and the intra and interday inaccuracy ranged from -8.1 to 13.5%. LTG was extracted from rat plasma and brain homogenate samples with an average absolute recovery ranging from 68.0 to 86.7%, and its stability was demonstrated in the assayed conditions. No interferences were observed at the retention times of the analyte (LTG) and IS. To the best of our knowledge, this is the first bioanalytical assay that uses MEPS procedure for the determination of LTG not only in rat plasma but also in tissue (brain) samples. This novel method was successfully applied to a preliminary pharmacokinetic study in rats and it seems to be a cost-effective tool to support non-clinical pharmacokinetic-based studies involving LTG treatment. PMID- 27697729 TI - Method development and validation for simultaneous quantitation of endogenous hippuric acid and phenylacetylglycine in rat urine using liquid chromatography coupled with electrospray ionization tandem mass spectrometry. AB - Urinary hippuric acid (HA) and phenylacetylglycine (PAG) are biomarker candidates for drug-induced phospholipidosis (PLD). To confirm their utility in preclinical and clinical settings, it is essential to develop and validate their quantification method in advance. In this study, we have applied liquid chromatography-tandem mass spectrometry (LC/MS/MS) for simultaneous quantification of HA and PAG in rat urine, and matrix based ion suppression was assessed by post-column infusion assay. Effective sample dilution reduced matrix effect of urine to be negligible level and calibration curves showed good correlation between those in urine diluent and buffer alone. Reliability of this assay was confirmed by the assessments for intra- and inter-day precisions and accuracies of quality control samples. The method was applied to rat urine after multiple oral administrations of PLD-inducing drugs, and the changes in HA and PAG concentrations and their ratio were successfully detected as rat plasma in previous report. This is the first report to quantify HA and PAG easily and accurately as potential biomarkers to monitor PLD status. This assay would be useful tool for monitoring PLD in toxicological studies by non-invasive sampling. PMID- 27697730 TI - Method for determination of streptomycin and streptidine as markers for streptomycin industrial dregs monitoring in pig and poultry compound feeds. AB - Antibiotic industrial dregs, generated from the production of antibiotics by fermentation, are banned in China as animal feed additives. Official monitoring programs require the analysis of feeds for possible illegal use of the dregs. A rapid and sensitive method was developed for the simultaneous determination of streptomycin and streptidine as markers for streptomycin industrial dregs in pig and poultry compound feeds. After extraction with 20% aqueous trichloroacetic acid and pH adjustment, sample cleanup was performed by weak cation-exchange solid-phase extraction. UPLC-ESI-MS/MS was carried out using a hydrophilic interaction chromatography(HILIC)column to achieve separation. Quantification required matrix-matched calibrations in a linear range of 50-1000MUgkg-1; the calibration curves were linear in this range with coefficients of determination of 0.991 and 0.994 for streptomycin and streptidine, respectively. The method validity parameters-LODs (20MUgkg-1) and LOQs (50MUgkg-1), recoveries (71-78% and 75-84%, respectively), and relative reproducibility (5.4-9.6%)-satisfy the requirements of routine analysis. PMID- 27697731 TI - Identification and quantification of synthetic cathinones in blood and urine using liquid chromatography-quadrupole/time of flight (LC-Q/TOF) mass spectrometry. AB - Synthetic cathinones continue to present a formidable challenge to forensic toxicology laboratories despite the fact that they are often encountered in impaired driving and death investigations. Due to limitations in immunoassay based screening technologies, many forensic toxicology laboratories must rely on more labor intensive chromatographic-based screening approaches in order to detect these drugs in biological evidence. Solid phase extraction (SPE) and liquid chromatography-quadrupole/time of flight (LC-Q/TOF) mass spectrometry were used to identify twenty-two synthetic cathinones in urine and blood. Target drugs included methcathinone, ethcathinone, pentedrone, buphedrone, 3 fluoromethcathinone (3-FMC), 4-fluoromethcathinone (4-FMC), 4-methylethcathinone (4-MEC), 4-ethylmethcathinone (4-EMC), mephedrone, methedrone, 3,4 dimethylmethcathinone (3,4-DMMC), ethylone, butylone, pentylone, eutylone, methylone, methylenedioxypyrovalerone (MDPV), 4-methylpyrrolidinobutiophenone (MPBP), 3,4-methylenedioxypyrrolidinobutiophenone (MDPBP), alpha pyrrolidinopentiphenone (alpha-PVP), pyrovalerone, and naphyrone. A total of nine deuterated internal standards were employed. Using traditional reversed phase chromatography all positional isomers, including 3-FMC and 4-FMC, were separated in 12min. The procedure was validated in accordance with the Scientific Working Group for Forensic Toxicology (SWGTOX) Standard Practices for Method Validation. Extraction efficiencies were 84-104% and 81-93% in urine and blood, respectively. Limits of quantitation in both matrices were 0.25-5ng/mL. Precision, bias and matrix effect were all within acceptable thresholds and the assay was free from more than fifty interferences. The validated method was used to identify cathinones in authentic urine case samples (n=20) and these results highlight important considerations for cathinone stability and the subsequent interpretation of results.

AB - This study aimed to asses maturity indices of rock phosphate enriched composts using crop residues having variable C/N ratios. There were distinct differences in concentration of NH4+-N, NO3--N, Olsen-P and NH4OAc-K for composts generated from different crop residues, the highest being in rice straw. Water soluble P varied from 3.47-4.45% of total P, while citrate soluble P varied from 32.7-54.0% of total P. Rice straw composts showed lower C/N, WSC/Org-N and E4/E6 ratio and higher germination index indicating that they are well-matured and stabilized compost. The relative order of performance of crop residues in aggrading compost quality was chickpea stover>rice straw>mustard stover>wheat straw>tree leaves. The results demonstrated that all the enriched composts had higher contents of available nutrients and quality indices, indicating that enriched composts could be used to substitute costly chemical fertilizers for crop production. PMID- 27697733 TI - A novel recycling system for nano-magnetic molecular imprinting immobilised cellulases: Synergistic recovery of anthocyanin from fruit and vegetable waste. AB - Fruit and vegetable waste (FVW) is become a serious problem in developing countries. Enzymolysis is a potentially useful method for the treatment of FVW. In the present study, novel recycled magnetic molecular imprinting immobilised cellulases were prepared based on magnetic modified chitosan (MCTS) and Fe3O4. The properties of obtained were characterised by IR and grain-size measurements. Evaluation of a single factor affecting the loading efficiency of supports and the mixed immobilised enzymes showed better capacity than single immobilised, or free, enzymes. The immobilisation process could improve cellulase stability and repeatability of the method. Meanwhile, the kinetic parameters were also verified. The immobilised enzymes retained most of their capacity after 60days' storage while free enzymes lost it within 30days. Tests showed that the immobilised enzymes developed excellent capacity and five anthocyanins were collected. PMID- 27697734 TI - Omics-based approaches reveal phospholipids remodeling of Rhizopus oryzae responding to furfural stress for fumaric acid-production from xylose. AB - In order to relieve the toxicity of furfural on Rhizopus oryzae fermentation, the molecular mechanism of R. oryzae responding to furfural stress for fumaric acid production was investigated by omics-based approaches. In metabolomics analysis, 29 metabolites including amino acid, sugars, polyols and fatty acids showed significant changes for maintaining the basic cell metabolism at the cost of lowering fumaric acid production. To further uncover the survival mechanism, lipidomics was carried out, revealing that phosphatidylcholine, phosphatidylglycerol, phosphatidylinositol and polyunsaturated acyl chains might be closely correlated with R. oryzae's adapting to furfural stress. Based on the above omics analysis, lecithin, inositol and soybean oil were exogenously supplemented separately with an optimized concentration in the presence of furfural, which increased fumaric acid titer from 5.78g/L to 10.03g/L, 10.05g/L and 12.13g/L (increased by 73.5%, 73.8% and 110%, respectively). These findings provide a methodological guidance for hemicellulose-fumaric acid development. PMID- 27697735 TI - Treatment of anaerobically digested swine wastewater by Rhodobacter blasticus and Rhodobacter capsulatus. AB - Two strains of photosynthetic bacteria, Rhodobacter blasticus and Rhodobacter capsulatus, were used in this work to investigate the feasibility of using photosynthetic bacteria for the treatment of anaerobically digested swine wastewater. The effects of crucial factors which influence the pollutants removal efficiency were also examined. Results showed that anaerobically digested swine wastewater could be treated effectively by photosynthetic bacteria. The treatment efficiency was significantly higher by the mixed photosynthetic bacteria than that by any unitary bacterium. The optimal treatment condition by mixed bacteria was inoculation of 10.0%(v/v) of the two bacteria by 1:1, initial pH of 7.0 and initial chemical oxygen demand of 4800mgL-1. Under these conditions, the removal rate of chemical oxygen demand was 83.3%, which was 19.3% higher than when using Rhodobacter blasticus or 10.6% higher than when using Rhodobacter capsulatus separately. This mixed photosynthetic bacteria achieved high chemical oxygen demand removal and cell yields. PMID- 27697736 TI - Mathematical modeling of nitrous oxide production in an anaerobic/oxic/anoxic process. AB - This study incorporates three currently known nitrous oxide (N2O) production pathways: ammonium-oxidizing bacteria (AOB) denitrification, incomplete hydroxylamine (NH2OH) oxidation, and heterotrophic denitrification on intracellular polymers, into a mathematical model to describe N2O production in an anaerobic/oxic/anoxic (AOA) process for the first time. The developed model was calibrated and validated by four experimental cases, then evaluated by two independent anaerobic/aerobic (AO) studies from literature. The modeling results displayed good agreement with the measured data. N2O was primarily generated in the aerobic stage by AOB denitrification (67.84-81.64%) in the AOA system. Smaller amounts of N2O were produced via incomplete NH2OH oxidation (15.61 32.17%) and heterotrophic denitrification on intracellular polymers (0-12.47%). The high nitrite inhibition on N2O reductase led to the increased N2O accumulation in heterotrophic denitrification on intracellular polymers. The new model was capable of modeling nitrification-denitrification dynamics and heterotrophic denitrification on intracellular polymers in the AOA system. PMID- 27697737 TI - A three-dimensional spatial characterization of the crossed-hands deficit. AB - To perceive the location of touch in space, we integrate information about skin location with information about the location of that body part in space. Most research investigating this process of tactile spatial remapping has used the so called crossed-hands deficit, in which the ability to judge the temporal order of touches on the two hands is impaired when the arms are crossed. This posture induces a conflict between skin-based and tactile external spatial representations, specifically in the left-right dimension. Thus, it is unknown whether touch is affected by posture when spatial relations other than the right left dimension are available. Here, we tested the extent to which the crossed hands deficit is a measure of tactile remapping, reflecting tactile encoding in three-dimensional space. Participants judged the temporal order of tactile stimuli presented to crossed and uncrossed hands. The arms were placed at different elevations (up-down dimension; Experiments 1 and 2), or at different distances from the body in the depth plane (close-far dimension; Experiment 3). The crossed-hands deficit was reduced when other sources of spatial information, orthogonal to the left-right dimension (i.e., close-far, up-down), were available. Nonetheless, the deficit persisted in all conditions, even when processing of non-conflicting information in the close-far or up-down dimensions was enough to solve the task. Together, these results demonstrate that the processing underlying the crossed-hands deficit is related to the encoding of tactile localization in three-dimensional space, rather than related uniquely to the cost of processing information in the right-left dimension. Furthermore, the persistence of the crossing effect provides evidence for automatic integration of all available information during the encoding of tactile information. PMID- 27697738 TI - Langmuir films of dipalmitoyl phosphatidylethanolamine grafted poly(ethylene glycol). In-situ evidence of surface aggregation at the air-water interface. AB - The molecular packing-dependent interfacial organization of polyethylene glycol grafted dipalmitoylphosphatidylethanolamine (PE-PEGs) Langmuir films was studied. The PEG chains covered a wide molecular mass range (350, 1000 and 5000Da). In surface pressure-area (pi-A), isotherms PE-PEG1000 and PE-PEG5000 showed transitions (midpoints at pim,t1~11mN/m, "t1"), which appeared as a long non horizontal line region. Thus, t1 cannot be considered a first-order phase transition but may reflect a transition within the polymer, comprising its desorption from the air-water interface and compaction upon compression. This is supported by the increase in the nus(C-O-C) PM-IRRAS signal intensity and the increasing surface potentials at maximal compression, which reflect thicker polymeric layers. Furthermore, changes in hydrocarbon chain (HC) packing and tilt with respect to the surface led to reorientation in the PO2- group upon compression, indicated by the inversion of the nuasym(PO2-) PM-IRRAS signal around t1. The absence of a t1 in PE-PEG350 supports the requisite of a critical polymer chain length for this transition to occur. In-situ epifluorescence microscopy revealed 2D-domain-like structures in PE-PEG1000 and PE-PEG5000 around t1, possibly associated with gelation/dehydration of the polymeric layer and appearing at decreasing pi as the polymeric tail became longer. Another transition, t2, appearing in PE-PEG350 and PE-PEG1000 at pim,t2=29.4 and 34.8mN/m, respectively, was associated with HC condensation and was impaired in PE-PEG5000 due to steric hindrance imposed by the large size of its polymer moiety. Two critical lengths of polymer chains were found, one of which allowed the onset of polymeric-tail gelation and the other limited HC compaction. PMID- 27697739 TI - Nanocarriers enhance the transdermal bioavailability of resveratrol: In-vitro and in-vivo study. AB - The aim of this study was to develop and assess the potential of nanostructured emulsion carriers for resveratrol topical application. Different compositions of resveratrol-loaded nanostructured emulsions were prepared using different types and amounts of surfactants and oily phases (isopropyl myristate and caproyl 90). The produced nanostructured emulsions were within the nanosized range 23.4 422.2nm with low viscosity range 2.15-17.53cps. The transdermal amount and deposition amount in the skin after 24 applications of resveratrol-loaded nanostructured emulsion were significantly increased about 896.2-fold and 10.2 fold respectively, when compared to the drug-saturated solution-treated group. Nanostructured emulsion containing IPM and low amounts of mixed surfactant of Tween80/Span 20 showed highest permeation capacity. In vivo study showed that the plasma concentration of resveratrol could be maintained at high levels for a long time after topical application of drug-loaded nanostructured emulsion. The histological examination demonstrated that the free drug- and drug-loaded nanostructured emulsion demonstrated considerably less irritation than the standard irritation group (0.8% paraformaldehyde-treated). The residual contents of resveratrol in the tested formulations after 3 months of storage at 25 degrees C and 40 degrees C were more than 99.97+/-3.90%. The results of present work confirm the high potential of nanostructured emulsion as carriers for drug topical application. PMID- 27697740 TI - Mechanism of adsorption of single and double stranded DNA on gold and silver nanoparticles: Investigating some important parameters in bio-sensing applications. AB - The mechanism of adsorption of single and double stranded DNAs on colloidal gold and silver nanoparticles has been studied by measuring the resistance of the nanoparticles, surrounded by various oligonucleotides, against salt induced aggregation. It is shown that both single and double stranded DNAs can be adsorbed on the metal nanoparticles and the adsorption strength is determined by the interaction between various bases of DNA and the nanoparticles. By changing the salt concentration, the difference between adsorption of various DNA strands on the nanoparticles can be specified. The results indicate that a key parameter in success of a sensing assay of DNA hybridization is the salt concentration which should be greater than a minimum threshold depending on the nanoparticles characteristics. We have also investigated the interaction mechanism between various DNA bases with the metal nanoparticles. For both gold and silver nanoparticles, adenine has the highest and thymine has the lowest attachment to the nanoparticles. From surface enhanced Raman spectroscopy (SERS) data of various bases in the presence of gold nanoparticles, the probable interaction points in the bases with the nanoparticles have been determined, which are mainly the nitrogen sites of these oligonucleotides. PMID- 27697741 TI - Impacts of low socioeconomic status and polycyclic aromatic hydrocarbons exposure on lung function among a community-based Chinese population. AB - Lung function is related to socioeconomic status (SES) and exposure to polycyclic aromatic hydrocarbons (PAHs). However, joint effect of SES and exposure to PAHs on lung function has been largely unknown. We aimed to investigate joint effects of SES and urinary OH-PAHs levels on lung function parameters. This study included 2739 Wuhan participants from the baseline survey of the Wuhan-Zhuhai (WHZH) Cohort Study (n=3053). They completed the questionnaire, physical examination and provided blood and urine samples. Twelve urinary monohydroxy-PAHs metabolites (OH-PAHs) and lung function were measured by gas chromatography-mass spectrometry and digital spirometers, respectively. Individuals with low educational levels and low or high levels of urinary SigmaOH-PAHs had a 3.5% (95% CI: -5.4, -1.6%) or 4.2% (95% CI: -6.1, -2.3%) reduction in the ratio of forced expiratory volume in 1s to forced vital capacity (FEV1/FVC), respectively, and those with middle levels of education and high levels of urinary SigmaOH-PAHs had a 2.1% (95% CI: -5.4, -1.6%) reduction in the FEV1/FVC ratio, rather than those with high levels of education and low levels of urinary SigmaOH-PAHs. Individuals with low levels of education had a -3.0% (95% CI: -4.4, -1.6%) reduction in FEV1/FVC compared with individuals with high levels of education. Urinary OH-PAHs levels were marginally negatively related to FEV1 in all participants (p=0.073). The results indicated that there was a prominent effect of low levels of education and higher exposure to PAHs on lung function decline, indicating that it is a necessary to take measures to promote the education level and reduce exposure to environmental PAHs. PMID- 27697742 TI - The oxygen isotopic composition of phosphate in river water and its potential sources in the Upper River Taw catchment, UK. AB - The need to reduce both point and diffuse phosphorus pollution to aquatic ecosystems is widely recognised and in order to achieve this, identification of the different pollutant sources is essential. Recently, a stable isotope approach using oxygen isotopes within phosphate (delta18OPO4) has been used in phosphorus source tracing studies. This approach was applied in a one-off survey in September 2013 to the River Taw catchment in south-west England where elevated levels of phosphate have been reported. River water delta18OPO4 along the main channel varied little, ranging from +17.1 to +18.80/00. This was no >0.30/00 different to that of the isotopic equilibrium with water (Edelta18OPO4). The delta18OPO4 in the tributaries was more variable (+17.1 to +18.80/00), but only deviated from Edelta18OPO4 by between 0.4 and 0.90/00. Several potential phosphate sources within the catchment were sampled and most had a narrow range of delta18OPO4 values similar to that of river Edelta18OPO4. Discharge from two waste water treatment plants had different and distinct delta18OPO4 from one another ranging between +16.4 and +19.60/00 and similar values to that of a dairy factory final effluent (+16.5 to +17.80/00), mains tap water (+17.8 to +18.40/00), and that of the phosphate extracted from river channel bed sediment (+16.7 to +17.60/00). Inorganic fertilizers had a wide range of values (+13.3 to +25.90/00) while stored animal wastes were consistently lower (+12.0 to +15.00/00) than most other sources and Edelta18OPO4. The distinct signals from the waste water treatment plants were lost within the river over a short distance suggesting that rapid microbial cycling of phosphate was occurring, because microbial cycling shifts the isotopic signal towards Edelta18OPO4. This study has added to the global inventory of phosphate source delta18OPO4 values, but also demonstrated the limitations of this approach to identifying phosphate sources, especially at times when microbial cycling is high. PMID- 27697743 TI - EGR-1 is an active transcription factor in TGF-beta2-mediated small intestinal cell differentiation. AB - Human milk contains growth factors that maintain intestinal mucosal homeostasis, but the molecular mechanisms behind how these growth factors regulate gene transcription are largely unknown. In this study, IEC-6 (rat intestinal epithelial cells) cells were used as a model to study cell differentiation mediated by transforming growth factor-beta2 (TGF-beta2), the most abundant growth factor in human milk. We focused on the transcription factor early growth response-1 (EGR-1), as we found a robust and rapid response in our initial transcription factor screen. Immunoblotting and immunofluorescent assays confirmed the phenotype change upon TGF-beta2 treatment and EGR-1 stimulation in the nucleus, with maximum expression occurring at 1 h. Chromatin immunoprecipitation sequencing was performed to map genome-wide EGR-1 binding sites on more than 1800 genes, widely involved in processes such as gene expression, transcription, membrane invagination and metabolism. In particular, more than 15 Wnt signaling pathway genes have EGR-1 binding sites; among them, Axin1 was the limiting factor, ensuring proper beta-catenin accumulation in the cytoplasm. We further used chromatin immunoprecipitation quantitative PCR to validate that EGR-1 binds to the region of -636/-454 bp and -454/-200 bp of the Axin1 promoter and functionally activates gene expression. The effect of TGF beta2 on maintaining small intestinal cell homeostasis was partially explained by Axin1 activation through EGR-1. PMID- 27697744 TI - Ternary nanohybrid of reduced graphene oxide-nafion@silver nanoparticles for boosting the sensor performance in non-enzymatic amperometric detection of hydrogen peroxide. AB - A sensitive and novel electrochemical sensor was developed for the detection of hydrogen peroxide (H2O2) using a reduced graphene oxide-nafion@silver6 (rGO Nf@Ag6) nanohybrid modified glassy carbon electrode (GC/rGO-Nf@Ag6). The GC/rGO Nf@Ag6 electrode exhibited an excellent electrochemical sensing ability for determining H2O2 with high sensitivity and selectivity. The detection limit of the electrochemical sensor using the GC/rGO-Nf@Ag6 electrode for H2O2 determination was calculated to be 5.35*10-7M with sensitivity of 0.4508uAuM-1. The coupling between rGO-Nf with silver nanoparticles (AgNPs) significantly boosted the electroanalytical performance by providing more active area for analyte interaction, thereby allowing more rapid interfacial electron transfer process. The interfering effect on the current response of H2O2 was studied and the results revealed that the sensor electrode exhibited an excellent immunity from most common interferents. The proposed non-enzymatic electrochemical sensor was used for determining H2O2 in apple juice, and the sensor electrode provided satisfactory results with reliable recovery values. These studies revealed that the novel GC/rGO-Nf@Ag6 sensor electrode could be a potential candidate for the detection of H2O2. PMID- 27697745 TI - Halide removal from aqueous solution by novel silver-polymeric materials. AB - The objective of this study was to analyze the behavior of a new material, silver doped polymeric cloth (Ag-cloth), in the removal of bromide and iodide from waters. Silver is immobilized on the cloth, guaranteeing selective adsorption of the halide ions as retained silver halides that therefore do not pass into the solution. Results indicate that Ag0 reacts with H2O2 in the first phases of the process, yielding Ag+ and superoxide radical; however, as the process advances, this radical favors Ag+ reduction. Increases in the concentration of H2O2 augment the capacity of the Ag-cloth to remove halides from the medium up to a maximum concentration (55MUM), above which the removal capacity remains constant (Xm?1.3 1.8mg halide/g Ag-cloth). Thus, when there is excess H2O2 in the medium, secondary competitive reactions that take place in the process guarantee a constant Ag+ concentration, which defines the maximum adsorption capacity of Ag cloth, reducing its ability to remove halides. Ag-cloth has a higher capacity to remove iodide than bromide, and the presence of organic matter or chloride reduces its capacity to remove iodide or bromide from water. The results obtained shown that the capacity of Ag0 with H2O2 significantly varies as a function of the medium pH from 1mg Br-/g Ag-cloth at very low pH to 1.6mg/g Ag-cloth at pH9. PMID- 27697746 TI - Atypical reactivity of heart rate variability to stress and depression across development: Systematic review of the literature and directions for future research. AB - Heart rate variability has received growing attention in the depression literature, with several recent meta-analyses indicating that lower resting heart rate variability is associated with depression. However, the role of fluctuations in heart rate variability (or reactivity) in response to stress in depression remains less clear. The present review provides a systematic examination of the literature on heart rate variability reactivity to a laboratory-induced stressor task and depression, including 26 studies of reactivity in heart rate variability and clinical depression, remitted (or history of) depression, and subthreshold depression (or symptom-level depression) among adults, adolescents, and children. In addition to reviewing the findings of these studies, methodological considerations and conceptual gaps in the literature are addressed. We conclude by highlighting the importance of investigating the potential transactional relationship between heart rate variability reactivity and depression and possible mechanisms underlying this relationship. PMID- 27697747 TI - Are Fish Consumption Advisories for the Great Lakes Adequately Protective against Chemical Mixtures? AB - BACKGROUND: The North American Great Lakes are home to > 140 types of fish and are famous for recreational and commercial fishing. However, the presence of toxic substances has resulted in the issuance of fish consumption advisories that are typically based on the most restrictive contaminant. OBJECTIVES: We investigated whether these advisories, which typically neglect the existence of a mixture of chemicals and their possible additive adverse effects, are adequately protective of the health of humans consuming fish from the Canadian waters of the Great Lakes. METHODS: Using recent fish contaminant monitoring data collected by the government of Ontario, Canada, we simulated advisories using most-restrictive contaminant (one-chem) and multi-contaminant additive effect (multi-chem) approaches. The advisories from the two simulations were compared to determine if there is any deficiency in the currently issued advisories. RESULTS: Approximately half of the advisories currently issued are potentially not adequately protective. Of the four Great Lakes studied, the highest percentage of advisories affected are in Lake Ontario if an additive effect is considered. Many fish that are popular for consumption, such as walleye, salmon, bass and trout, would have noticeably more stringent advisories. CONCLUSIONS: Improvements in the advisories may be needed to ensure that the health of humans consuming fish from the Great Lakes is protected. In this region, total polychlorinated biphenyls (PCBs) and mercury are the major contaminants causing restrictions on consuming fish, whereas dioxins/furans, toxaphene, and mirex/photomirex are of minor concern. Regular monitoring of most organochlorine pesticides and metals in fish can be discontinued. PMID- 27697749 TI - ENHANCE-(Electronic Hydroxyurea Adherence): A Protocol to Increase Hydroxyurea Adherence in Patients with Sickle Cell Disease. AB - BACKGROUND: Hydroxyurea (HU) is the only disease-modifying medication for patients with sickle cell disease (SCD). HU can reduce SCD-related complications but only 35% to 50% of pediatric patients adhere to HU at the rates achieved in clinical trials and this limits its clinical effectiveness. Mobile Directly Observed Therapy (Mobile DOT) is a pilot-tested, electronic, multidimensional, HU adherence intervention that targets many components of the Health Behavior Model. OBJECTIVE: The aim of this study is to evaluate the impact of Mobile DOT on HU adherence in children with SCD. The objective of our study is to inform the development of future adherence interventions and pediatric SCD protocols. METHODS: This is a single-arm crossover study of pediatric patients with SCD. Participants self-record videos of their daily HU administrations and receive text message alerts to take HU, feedback on their HU adherence, and incentives when they achieve adherence goals during the 6-month Mobile DOT phase. Participants' HU adherence during the Mobile DOT phase is compared with their baseline HU adherence (6 months prior to study entry) and to their HU adherence 6 months after completing the Mobile DOT phase. The primary outcome of this study is HU adherence measured by medication possession ratio. RESULTS: The trial is ongoing. Preliminary review of participant satisfaction results suggest that most participants can complete Mobile DOT in less than 5 minutes per day and are satisfied with the intervention. CONCLUSIONS: If effective, the Mobile DOT strategy will increase HU adherence and this could improve patients' clinical outcomes and reduce costs of care. PMID- 27697748 TI - "I Want to Keep the Personal Relationship With My Doctor": Understanding Barriers to Portal Use among African Americans and Latinos. AB - BACKGROUND: Despite the widespread implementation of electronic health records (EHRs), there is growing evidence that racial/ethnic minority patients do not use portals as frequently as non-Hispanic whites to access their EHR information online. This differential portal use could be problematic for health care disparities since early evidence links portal use to better outcomes. OBJECTIVE: We sought to understand specific barriers to portal use among African American and Latino patients at Kaiser Permanente, which has had a portal in place for over a decade, and broad uptake among the patient population at large. METHODS: We conducted 10 focus groups with 87 participants in 2012 and 2013 among African American and Latino Kaiser Permanente members in the mid-Atlantic, Georgia, and Southern California regions. Members were eligible to participate if they were not registered for portal access. Focus groups were conducted within each racial/ethnic group, and each included individuals who were older, had a chronic disease, or were parents (as these are the three biggest users of the portal at Kaiser Permanente overall). We videotaped each focus group and transcribed the discussion for analysis. We used general inductive coding to develop themes for major barriers to portal use, overall and separately by racial/ethnic group. RESULTS: We found that lack of support was a key barrier to initiating portal use in our sample-both in terms of technical assistance as well as the fear of the portal eroding existing personal relationships with health care providers. This held true across a range of focus groups representing a mix of age, income, health conditions, and geographic regions. CONCLUSIONS: Our study was among the first qualitative explorations of barriers to portal use among racial/ethnic subgroups. Our findings suggest that uniform adoption of portal use across diverse patient groups requires more usable and personalized websites, which may be particularly important for reducing health care disparities. This work is particularly important as all health care systems continue to offer and promote more health care features online via portals. PMID- 27697750 TI - Assessing the Impact and Cost of Short-Term Health Workforce in Remote Indigenous Communities in Australia: A Mixed Methods Study Protocol. AB - BACKGROUND: Remote Australia is a complex environment characterized by workforce shortages, isolated practice, a large resident Indigenous population, high levels of health need, and limited access to services. In recent years, there has been an increasing trend of utilizing a short-term visiting (fly-in/fly-out) health workforce in many remote areas. However, there is a dearth of evidence relating to the impact of this transitory workforce on the existing resident workforce, consumer satisfaction, and the effectiveness of current services. OBJECTIVE: This study aims to provide rigorous empirical data by addressing the following objectives: (1) to identify the impact of short-term health staff on the workload, professional satisfaction, and retention of resident health teams in remote areas; (2) to identify the impact of short-term health staff on the quality, safety, and continuity of patient care; and (3) to identify the impact of short-term health staff on service cost and effectiveness. METHODS: Mixed methods will be used. Administrative data will be extracted that relates to all 54 remote clinics managed by the Northern Territory Department of Health, covering a population of 35,800. The study period will be 2010 to 2014. All 18 Aboriginal Community-Controlled Health Services in the Northern Territory will also be invited to participate. We will use these quantitative data to describe staffing stability and turnover in these communities, and then utilize multiple regression analyses to determine associations between the key independent variables of interest (resident staff turnover, stability or median survival, and socioeconomic status, community size, and per capita funding) and dependent variables related to patient care, service cost, quality, and effectiveness. The qualitative component of the study will involve in-depth interviews and focus groups with staff and patients, respectively, in six remote communities. Three communities will be high staff turnover communities and three characterized by low turnover. This will provide information on service quality, impact on resident and visiting staff, and patient satisfaction with the services. The research team will work with staff, patients, and a key stakeholder group of senior policymakers to develop workforce strategies to maintain or attain remote health workforce stability. RESULTS: The study commenced in 2015. As of October 2016, fieldwork has been almost completed and quantitative analysis has commenced. Results are expected to be published in 2017. CONCLUSIONS: The study has commenced, but it is too early to provide results or conclusions. PMID- 27697751 TI - MiR-495 functions as an adjuvant to radiation therapy by reducing the radiation induced bystander effect. AB - The radiation-induced bystander effect (RIBE) is an important factor in tumor radiation therapy because it may increase the probability of normal cellular injury and the likelihood of secondary cancers after radiotherapy. Here, we identified the role of miR-495 in alleviating RIBEs during radiotherapy. Luciferase reporter assay results confirmed that miR-495 regulated endothelial nitric oxide synthase (eNOS) by targeting the Sp1 3'-untranslated region. Consequently, after radiation, tumor cells expressed less eNOS and Sp1 than controls. In vitro cell irradiation data based on flow-cytometric analysis and enzymed linked immunosorbent assay confirmed that nitric oxide (NO) and its downstream product transforming growth factor beta1 (TGF-beta1) were critical signaling factors contributing to RIBEs. Fewer normal LO2 liver cells were injured and fewer micronuclei were observed when treated with the medium of the miR-495 overexpressing HepG2 and ZR75-1 tumor cells. Accordingly, treatment with the miR-495 antagomir led to higher NO and TGF-beta1 levels and more injured LO2 cells. In vivo experiments indicated that local irradiation of tumors overexpressing miR-495 produced fewer necrotic foci in non-irradiated liver tissue compared with controls. miR-495 was upregulated in clinical cancer tissues compared with adjacent non-cancerous tissues, and radiation significantly reduced the expression level of miR-495 in carcinoma cell lines. In summary, miR-495 may have promise as an adjuvant for tumor radiation therapy to decrease RIBEs involving the Sp1/eNOS pathway.

PMID- 27697754 TI - Risk of leukaemia is no higher in children living near UK nuclear sites, finds report. PMID- 27697752 TI - Plasminogen Activator Inhibitor-1 and Diagnosis of the Metabolic Syndrome in a West African Population. AB - BACKGROUND: Metabolic syndrome (MetS) is diagnosed by the presence of at least 3 of the following: obesity, hypertension, hyperglycemia, hypertriglyceridemia, and low high-density lipoprotein. Individuals with MetS also typically have elevated plasma levels of the antifibrinolytic factor, plasminogen activator inhibitor-1 (PAI-1), but the relationships between PAI-1 and MetS diagnostic criteria are not clear. Understanding these relationships can elucidate the relevance of MetS to cardiovascular disease risk, because PAI-1 is associated with ischemic events and directly involved in thrombosis. METHODS AND RESULTS: In a cross-sectional analysis of 2220 Ghanaian men and women from urban and rural locales, we found the age-standardized prevalence of MetS to be as high as 21.4% (urban women). PAI 1 level increased exponentially as the number of diagnostic criteria increased linearly (P<10-13), supporting the conclusion that MetS components have a joint effect that is stronger than their additive contributions. Body mass index, triglycerides, and fasting glucose were more strongly correlated with PAI-1 than with canonical MetS criteria, and this pattern did not change when pair-wise correlations were conditioned on all other risk factors, supporting an independent role for PAI-1 in MetS. Finally, whereas the correlations between conventional risk factors did not vary significantly by sex or across urban and rural environments, correlations with PAI-1 were generally stronger among urban participants. CONCLUSIONS: MetS prevalence in the West African population we studied was comparable to that of the industrialized West. PAI-1 may serve as a key link between MetS, as currently defined, and the endpoints with which it is associated. Whether this association is generalizable will require follow-up.

AB - Polymyxin B is increasingly used as a treatment of last resort for multidrug resistant Gram-negative infections. Despite being available as a mixture of several structurally related analogues, the properties are commonly reported as an aggregate of the individual components. We compared the pharmacokinetics of individual polymyxin B components in an animal model and in humans. There were no considerable differences observed in the pharmacokinetics among major components of polymyxin B. Combining different components for pharmacokinetic analysis appeared reasonable. PMID- 27697757 TI - Liver Fatty Acid Binding Protein Deficiency Provokes Oxidative Stress, Inflammation, and Apoptosis-Mediated Hepatotoxicity Induced by Pyrazinamide in Zebrafish Larvae. AB - Pyrazinamide (PZA) is an essential antitubercular drug, but little is still known about its hepatotoxicity potential. This study examined the effects of PZA exposure on zebrafish (Danio rerio) larvae and the mechanisms underlying its hepatotoxicity. A transgenic line of zebrafish larvae that expressed enhanced green fluorescent protein (EGFP) in the liver was incubated with 1, 2.5, and 5 mM PZA from 72 h postfertilization (hpf). Different endpoints such as mortality, morphology changes in the size and shape of the liver, histological changes, transaminase analysis and apoptosis, markers of oxidative and genetic damage, as well as the expression of certain genes were selected to evaluate PZA-induced hepatotoxicity. Our results confirm the manner of PZA dose-dependent hepatotoxicity. PZA was found to induce marked injury in zebrafish larvae, such as liver atrophy, elevations of transaminase levels, oxidative stress, and hepatocyte apoptosis. To further understand the mechanism behind PZA-induced hepatotoxicity, changes in gene expression levels in zebrafish larvae exposed to PZA for 72 h postexposure (hpe) were determined. The results of this study demonstrated that PZA decreased the expression levels of liver fatty acid binding protein (L-FABP) and its target gene, peroxisome proliferator-activated receptor alpha (PPAR-alpha), and provoked more severe oxidative stress and hepatitis via the upregulation of inflammatory cytokines such as tumor necrosis factor alpha (TNF-alpha) and transforming growth factor beta (TGF-beta). These findings suggest that L-FABP-mediated PPAR-alpha downregulation appears to be a hepatotoxic response resulting from zebrafish larva liver cell apoptosis, and L FABP can be used as a biomarker for the early detection of PZA-induced liver damage in zebrafish larvae. PMID- 27697758 TI - Pharmacokinetic Interactions between Tafenoquine and Dihydroartemisinin Piperaquine or Artemether-Lumefantrine in Healthy Adult Subjects. AB - Tafenoquine is in development as a single-dose treatment for relapse prevention in individuals with Plasmodium vivax malaria. Tafenoquine must be coadministered with a blood schizonticide, either chloroquine or artemisinin-based combination therapy (ACT). This open-label, randomized, parallel-group study evaluated potential drug interactions between tafenoquine and two ACTs: dihydroartemisinin piperaquine and artemether-lumefantrine. Healthy volunteers of either sex aged 18 to 65 years without glucose-6-phosphate dehydrogenase deficiency were randomized into five cohorts (n = 24 per cohort) to receive tafenoquine on day 1 (300 mg) plus once-daily dihydroartemisinin-piperaquine on days 1, 2, and 3 (120 mg/960 mg for 36 to <75 kg of body weight and 160 mg/1,280 mg for >=75 to 100 kg of body weight), or plus artemether-lumefantrine (80 mg/480 mg) in two doses 8 h apart on day 1 and then twice daily on days 2 and 3, or each drug alone. The pharmacokinetic parameters of tafenoquine, piperaquine, lumefantrine, artemether, and dihydroartemisinin were determined by using noncompartmental methods. Point estimates and 90% confidence intervals were calculated for area under the concentration-time curve (AUC) and maximum observed plasma concentration (Cmax) comparisons of tafenoquine plus ACT versus tafenoquine or ACT. All subjects receiving dihydroartemisinin-piperaquine experienced QTc prolongation (a known risk with this drug), but tafenoquine coadministration had no clinically relevant additional effect. Tafenoquine coadministration had no clinically relevant effects on dihydroartemisinin, piperaquine, artemether, or lumefantrine pharmacokinetics. Dihydroartemisinin-piperaquine coadministration increased the tafenoquine Cmax by 38% (90% confidence interval, 25 to 52%), the AUC from time zero to infinity (AUC0-infinity) by 12% (1 to 26%), and the half-life (t1/2) by 29% (19 to 40%), with no effect on the AUC from time zero to the time of the last nonzero concentration (AUC0-last). Artemether-lumefantrine coadministration had no effect on tafenoquine pharmacokinetics. Tafenoquine can be coadministered with dihydroartemisinin-piperaquine or artemether-lumefantrine without dose adjustment for any of these compounds.

PMID- 27697759 TI - Risk Factors, Outcomes, and Mechanisms of Tigecycline-Nonsusceptible Klebsiella pneumoniae Bacteremia. AB - A rise in tigecycline resistance in Klebsiella pneumoniae has been reported recently worldwide. We sought to identify risk factors, outcomes, and mechanisms for adult patients with tigecycline-nonsusceptible K. pneumoniae bacteremia in Taiwan. We conducted a matched case-control study (ratio of 1:1) in a medical center in Taiwan from January 2011 through June 2015. The cases were patients with tigecycline-nonsusceptible K. pneumoniae bacteremia, and the controls were patients with tigecycline-susceptible K. pneumoniae bacteremia. Logistic regression was performed to evaluate the potential risk factors for tigecycline nonsusceptible K. pneumoniae bacteremia. Quantitative reverse transcription-PCR was performed to analyze acrA, oqxA, ramA, rarA, and kpgA expression among these isolates. A total of 43 cases were matched with 43 controls. The 14-day mortality of patients with tigecycline-nonsusceptible K. pneumoniae bacteremia was 30.2%, and the 28-day mortality was 41.9%. The attributable mortalities of tigecycline nonsusceptible K. pneumoniae at 14 and 28 days were 9.3 and 18.6%, respectively. Fluoroquinolone use within 30 days prior to bacteremia was the only independent risk factor for tigecycline-nonsusceptible K. pneumoniae bacteremia. The tigecycline-nonsusceptible K. pneumoniae bacteremia was mostly caused by overexpression of AcrAB and/or OqxAB efflux pumps, together with the upregulation of RamA and/or RarA, respectively. One isolate demonstrated isolated overexpression of kpgA In conclusion, tigecycline-nonsusceptible K. pneumoniae bacteremia was associated with high mortality, and prior fluoroquinolone use was the independent risk factor for the acquisition of tigecycline-nonsusceptible K. pneumoniae The overexpression of AcrAB and/or OqxAB contributes to tigecycline nonsusceptibility in K. pneumoniae. PMID- 27697760 TI - Pharmacokinetics of the Antischistosomal Lead Ozonide OZ418 in Uninfected Mice Determined by Liquid Chromatography-Tandem Mass Spectrometry. AB - One of the major neglected tropical diseases, schistosomiasis, is currently treated and controlled with a single drug, praziquantel. The quest for an alternative drug is fueled by the lack of activity of praziquantel against juvenile Schistosoma worms and the fear of emerging resistance. The synthetic ozonide OZ418 has shown high activity against Schistosoma mansoni, S. haematobium, and S. japonicum in vivo, but its drug disposition remains unknown. To bridge this gap, our study determined the basic pharmacokinetic (PK) parameters of a single oral dose (400 mg/kg of body weight) of OZ418 in uninfected mice. First, a simple liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to quantify OZ418 concentrations in mouse plasma was successfully developed and validated according to U.S. FDA guidelines. This method proved to be selective, accurate (93 to 103%), precise (5 to 16%), and devoid of significant matrix effects (90 to 102%) and provided excellent recovery (101 to 102%). A median peak concentration of 190 (range, 185 to 231) MUg/ml was reached at 2 h (2 to 3 h) posttreatment. A naive pooled noncompartmental PK analysis estimated a mean area under the plasma concentration-versus-time curve (AUC) of 9,303 MUg h/ml (7,039.2 to 11,908.5 MUg h/ml) and a half-life of 38.7 h (20 to 64.6 h). Thus, the OZ418 level in plasma remained well above its in vitro 50% inhibitory concentrations (IC50s) of 27.4 MUg/ml (adult S. mansoni worms at 72 h) for at least 75 h. Consistently, OZ418 degraded little in plasma at 37 degrees C (<20% in 121 h) and weakly inhibited cytochrome P450 (CYP450) metabolism (IC50 of 37 to 144 MUM). Our results provide a first insight into the disposition of OZ418, paving the way for further studies of its biological fate and effect. PMID- 27697761 TI - High-Dose Micafungin for Preterm Neonates and Infants with Invasive and Central Nervous System Candidiasis. AB - High doses of micafungin are advocated in neonates with systemic candidiasis, but limited pharmacokinetic (PK) and safety data are available to support their use. Eighteen preterm neonates and infants with systemic candidiasis, three of whom had meningitis, were treated for at least 14 days with 8 to 15 mg/kg of body weight/day of intravenous micafungin. Plasma micafungin concentrations (four measurements for each patient) were determined after the third dose, and the cerebrospinal fluid (CSF) micafungin concentrations in three patients were also obtained. Population PK analyses were used to identify the optimal model, and the model was further validated using external data (n = 5). The safety of micafungin was assessed by measurement of the levels of liver and kidney function biomarkers. The mean age and weight at the initiation of treatment were 2.33 months (standard deviation [SD], 1.98 months) and 3.24 kg (SD, 1.61 kg), respectively. The optimal PK model was one that scaled plasma clearance to weight and the transaminase concentration ratio. The CSF of three patients was sampled, and the observed concentrations were between 0.80 and 1.80 mg/liter. The model predicted mean micafungin area under the concentration-time curve over 24 h was 336 mg . h/liter (SD, 165 mg . h/liter) with the 10-mg/kg/day dosage. Eighteen of the 23 subjects (78.2%) had clinical resolution of their infection, but 5 had neurologic impairments. Among the transaminases, alkaline phosphatase measurements were significantly higher posttreatment, with a geometric mean ratio of 1.17 (90% confidence interval, 1.01, 1.37). Furthermore, marked elevations in the gamma-glutamyltransferase (GGT) level were observed in three patients treated with 10- to 15-mg/kg/day doses, and improvement of the GGT level was noted after a dose reduction. Higher weight-based doses of micafungin were generally well tolerated in neonates and infants and achieved pharmacokinetic profiles predictive of an effect. PMID- 27697763 TI - A Single Nucleotide Change in the Promoter mutp Enhances Fluoride Resistance of Streptococcus mutans. AB - Previously, we identified a single nucleotide mutation in the promoter (mutp) of the fluoride antiporter-coding genes in a naturally fluoride-resistant Streptococcus mutans strain. Here, we studied the role of this mutation in a defined genetic background. The results confirmed that this mutation alone confers fluoride resistance on S. mutans, as shown by growth and lactic acid production assays. This resistance was explained by constitutively higher mutp promoter activity and upregulation of the fluoride antiporter-coding genes. PMID- 27697762 TI - Population Pharmacokinetics of Liposomal Amphotericin B in Immunocompromised Children. AB - Liposomal amphotericin B (LAmB) is widely used in the treatment of invasive fungal disease (IFD) in adults and children. There are relatively limited pharmacokinetic (PK) data to inform optimal dosing in children that achieves systemic drug exposures comparable to those of adults. Our objective was to describe the pharmacokinetics of LAmB in children aged 1 to 17 years with suspected or documented IFD. Thirty-five children were treated with LAmB at doses of 2.5 to 10 mg kg-1 daily. Samples were taken at baseline and at 0.5- to 2.0-h intervals for 24 h after receipt of the first dose (n = 35 patients) and on the final day of therapy (n = 25 patients). LAmB was measured using high-performance liquid chromatography (HPLC). The relationship between drug exposure and development of toxicity was explored. An evolution in PK was observed during the course of therapy, resulting in a proportion of patients (n = 13) having significantly higher maximum serum concentrations (Cmax) and areas under the concentration-time curve from 0 to 24 h (AUC0-24) later in the course of therapy, without evidence of drug accumulation (trough plasma concentration accumulation ratio of <1.2). The fit of a 2-compartment model incorporating weight and an exponential decay function describing volume of distribution best described the data. There was a statistically significant relationship between mean AUC0-24 and probability of nephrotoxicity (odds ratio, 2.37; 95% confidence interval, 1.84 to 3.22; P = 0.004). LAmB exhibits nonlinear pharmacokinetics. A third of children appear to experience a time-dependent change in PK, which is not explained by weight, maturation, or observed clinical factors. PMID- 27697764 TI - Breaking the Permeability Barrier of Escherichia coli by Controlled Hyperporination of the Outer Membrane. AB - In Gram-negative bacteria, a synergistic relationship between slow passive uptake of antibiotics across the outer membrane and active efflux transporters creates a permeability barrier, which efficiently reduces the effective concentrations of antibiotics in cells and, hence, their activities. To analyze the relative contributions of active efflux and the passive barrier to the activities of antibiotics, we constructed Escherichia coli strains with controllable permeability of the outer membrane. The strains expressed a large pore that does not discriminate between compounds on the basis of their hydrophilicity and sensitizes cells to a variety of antibacterial agents. We found that the efficacies of antibiotics in these strains were specifically affected by either active efflux or slow uptake, or both, and reflect differences in the properties of the outer membrane barrier, the repertoire of efflux pumps, and the inhibitory activities of antibiotics. Our results identify antibiotics which are the best candidates for the potentiation of activities through efflux inhibition and permeabilization of the outer membrane. PMID- 27697765 TI - EULAR recommendations for cardiovascular disease risk management in patients with rheumatoid arthritis and other forms of inflammatory joint disorders: 2015/2016 update. AB - Patients with rheumatoid arthritis (RA) and other inflammatory joint disorders (IJD) have increased cardiovascular disease (CVD) risk compared with the general population. In 2009, the European League Against Rheumatism (EULAR) taskforce recommended screening, identification of CVD risk factors and CVD risk management largely based on expert opinion. In view of substantial new evidence, an update was conducted with the aim of producing CVD risk management recommendations for patients with IJD that now incorporates an increasing evidence base. A multidisciplinary steering committee (representing 13 European countries) comprised 26 members including patient representatives, rheumatologists, cardiologists, internists, epidemiologists, a health professional and fellows. Systematic literature searches were performed and evidence was categorised according to standard guidelines. The evidence was discussed and summarised by the experts in the course of a consensus finding and voting process. Three overarching principles were defined. First, there is a higher risk for CVD in patients with RA, and this may also apply to ankylosing spondylitis and psoriatic arthritis. Second, the rheumatologist is responsible for CVD risk management in patients with IJD. Third, the use of non-steroidal anti-inflammatory drugs and corticosteroids should be in accordance with treatment-specific recommendations from EULAR and Assessment of Spondyloarthritis International Society. Ten recommendations were defined, of which one is new and six were changed compared with the 2009 recommendations. Each designated an appropriate evidence support level. The present update extends on the evidence that CVD risk in the whole spectrum of IJD is increased. This underscores the need for CVD risk management in these patients. These recommendations are defined to provide assistance in CVD risk management in IJD, based on expert opinion and scientific evidence. PMID- 27697766 TI - EpCAM Inhibition Sensitizes Chemoresistant Leukemia to Immune Surveillance. AB - The lack of effective tumor-associated antigens restricts the development of targeted therapies against myeloid leukemia. In this study, we compared gene expression patterns of acute myeloid leukemia (AML) and normal bone marrow samples and found that epithelial cell adhesion molecule (EpCAM) is frequently overexpressed in patients with AML, with EpCAM+ leukemic cells exhibiting enhanced chemoresistance and oncogenesis. The chemotherapeutic resistance of EpCAM-positive leukemic cells is a consequence of increased WNT5B signaling. Furthermore, we generated EpCAM antibodies that enabled phagocytosis or cytotoxicity of AML cells by macrophage or natural killer cells, respectively. Finally, EpCAM antibody treatment depleted AML in subcutaneous, disseminated, and intramedullary engrafted mice. In summary, EpCAM exhibits promise as a novel target for the treatment of leukemia.

AB - There is a great need to develop novel approaches to target oncogenic transcription factors with small molecules. Ewing sarcoma is emblematic of this need, as it depends on the continued activity of the EWS-FLI1 transcription factor to maintain the malignant phenotype. We have previously shown that the small molecule trabectedin interferes with EWS-FLI1. Here, we report important mechanistic advances and a second-generation inhibitor to provide insight into the therapeutic targeting of EWS-FLI1. We discovered that trabectedin functionally inactivated EWS-FLI1 by redistributing the protein within the nucleus to the nucleolus. This effect was rooted in the wild-type functions of the EWSR1, compromising the N-terminal half of the chimeric oncoprotein, which is known to be similarly redistributed within the nucleus in the presence of UV light damage. A second-generation trabectedin analogue lurbinectedin (PM01183) caused the same nuclear redistribution of EWS-FLI1, leading to a loss of activity at the promoter, mRNA, and protein levels of expression. Tumor xenograft studies confirmed this effect, and it was increased in combination with irinotecan, leading to tumor regression and replacement of Ewing sarcoma cells with benign fat cells. The net result of combined lurbinectedin and irinotecan treatment was a complete reversal of EWS-FLI1 activity and elimination of established tumors in 30% to 70% of mice after only 11 days of therapy. Our results illustrate the preclinical safety and efficacy of a disease-specific therapy targeting the central oncogenic driver in Ewing sarcoma. Cancer Res; 76(22); 6657-68. (c)2016 AACR. PMID- 27697768 TI - Therapeutic effects of dry needling in patients with upper trapezius myofascial trigger points. AB - BACKGROUND: Active myofascial trigger points (MTrPs) are major pain generators in myofascial pain syndrome. Dry needling (DN) is an effective method for the treatment of MTrPs. OBJECTIVE: To assess the immediate neurophysiological and clinical effects of DN in patients with upper trapezius MTrPs. METHODS: This was a prospective, clinical trial study of 20 patients with upper trapezius MTrPs and 20 healthy volunteers (matched for height, weight, body mass index and age), all of whom received one session of DN. Primary outcome measures were neuromuscular junction response (NMJR) and sympathetic skin response (SSR). Secondary outcomes were pain intensity (PI) and pressure pain threshold (PPT). Data were collected at baseline and immediately post-intervention. RESULTS: At baseline, SSR amplitude was higher in patients versus healthy volunteers (p<0.003). With respect to NMJR, a clinically abnormal increment and normal reduction was observed in patients and healthy volunteers, respectively. Moreover, PPT of patients was less than healthy volunteers (p<0.0001). After DN, SSR amplitude decreased significantly in patients (p<0.01), but did not change in healthy volunteers. A clinically important reduction in the NMJR of patients and increment in healthy volunteers was demonstrated after DN. PPT increased after DN in patients, but decreased in healthy volunteers (p<0.0001). PI improved after DN in patients (p<0.001). CONCLUSIONS: The results of this study showed that one session of DN targeting active MTrPs appears to reduce hyperactivity of the sympathetic nervous system and irritability of the motor endplate. DN seems effective at improving symptoms and deactivating active MTrPs, although further research is needed. TRIAL REGISTRATION NUMBER: IRCT20130316128. PMID- 27697769 TI - Effects of myofascial trigger point dry needling in patients with sleep bruxism and temporomandibular disorders: a prospective case series. AB - OBJECTIVES: To investigate the effects of deep dry needling (DN) of myofascial trigger points (MTrPs) of the masseter and temporalis on pain, pressure pain threshold (PPT), pain-free maximal jaw opening and temporomandibular disorder (TMD)-related disability in patients with sleep bruxism (SB) and myofascial TMD. METHODS: Seventeen subjects (11 women, 6 men) aged 39+/-13 years (range 23-66) diagnosed with SB and myofascial TMD were invited to participate in this prospective case series study. Each subject received a deep DN intervention in the masseter and temporalis MTrPs. Pain intensity, PPT, pain-free maximal jaw opening and TMD-related disability were assessed before treatment, immediately after treatment and at 1-week follow-up. Jaw disability was assessed using the jaw disability checklist (JDC) at baseline and 1 week post-treatment only. RESULTS: One-way analyses of variance showed significant improvements in pain intensity, PPT and jaw opening (p<0.001). Post-hoc analysis revealed significant differences between baseline and post-intervention follow-up time points in pain (immediate: Cohen's d=1.72, p<0.001; 1 week: d=3.24, p<0.001), jaw opening (immediate: d=0.77, p<0.001; 1 week: d=1.02, p<0.001) and PPT in the masseter (immediate: d=1.02, p<0.001; 1 week: d=1.64, p<0.001) and temporalis (immediate: d=0.91, p=0.006; 1 week: d=1.8, p<0.001). A dependent t-test showed a significant improvement in jaw functioning, reflected by a large reduction in 1-week JDC scores relative to baseline (d=3.15, p<0.001). CONCLUSIONS: Deep DN of active MTrPs in the masseter and temporalis in patients with myofascial TMD and SB was associated with immediate and 1-week improvements in pain, sensitivity, jaw opening and TMD-related disability. TRIAL REGISTRATION NUMBER: NCT02587182; Results. PMID- 27697770 TI - Minimal residual disease is an independent predictor for 10-year survival in CLL. AB - Minimal residual disease (MRD) negativity, defined as <1 chronic lymphocytic leukemia (CLL) cell detectable per 10 000 leukocytes, has been shown to independently predict for clinical outcome in patients receiving combination chemoimmunotherapy in the frontline setting. However, the long-term prognostic value of MRD status in other therapeutic settings remains unclear. Here, we retrospectively analyzed, with up to 18 years follow-up, all patients at our institution who achieved at least a partial response (PR) with various therapies between 1996 and 2007, and received a bone marrow MRD assessment at the end of treatment according to the international harmonized approach. MRD negativity correlated with both progression-free survival (PFS) and overall survival (OS) independent of the type and line of treatment, as well as known prognostic factors including adverse cytogenetics. The greatest impact of achieving MRD negativity was seen in patients receiving frontline treatment, with 10-year PFS of 65% vs 10% and 10-year OS of 70% vs 30% for MRD-negative vs MRD-positive patients, respectively. Our results demonstrate the long-term benefit of achieving MRD negativity, regardless of the therapeutic setting and treatment modality, and support its use as a prognostic marker for long-term PFS and as a potential therapeutic goal in CLL. PMID- 27697771 TI - Phase 1 trial of rituximab, lenalidomide, and ibrutinib in previously untreated follicular lymphoma: Alliance A051103. AB - Chemoimmunotherapy in follicular lymphoma is associated with significant toxicity. Targeted therapies are being investigated as potentially more efficacious and tolerable alternatives for this multiply-relapsing disease. Based on promising activity with rituximab and lenalidomide in previously untreated follicular lymphoma (overall response rate [ORR] 90%-96%) and ibrutinib in relapsed disease (ORR 30%-55%), the Alliance for Clinical Trials in Oncology conducted a phase 1 trial of rituximab, lenalidomide, and ibrutinib. Previously untreated patients with follicular lymphoma received rituximab 375 mg/m2 on days 1, 8, 15, and 22 of cycle 1 and day 1 of cycles 4, 6, 8, and 10; lenalidomide as per cohort dose on days 1 to 21 of 28 for 18 cycles; and ibrutinib as per cohort dose daily until progression. Dose escalation used a 3+3 design from a starting dose level (DL) of lenalidomide 15 mg and ibrutinib 420 mg (DL0) to DL2 (lenalidomide 20 mg, ibrutinib 560 mg). Twenty-two patients were enrolled; DL2 was determined to be the recommended phase II dose. Although no protocol-defined dose-limiting toxicities were reported, a high incidence of rash was observed (all grades 82%, grade 3 36%). Eleven patients (50%) required dose reduction, 7 because of rash. The ORR for the entire cohort was 95%, and the 12-month progression-free survival was 80% (95% confidence interval, 57%-92%). Five patients developed new malignancies; 3 had known risk factors before enrollment. Given the increased toxicity and required dose modifications, as well as the apparent lack of additional clinical benefit to the rituximab-lenalidomide doublet, further investigation of the regimen in this setting seems unwarranted. The study was registered with www.ClinicalTrials.gov as #NCT01829568. PMID- 27697772 TI - Rational targeted therapies to overcome microenvironment-dependent expansion of mantle cell lymphoma. AB - Mantle cell lymphoma (MCL) accumulates in lymphoid organs, but disseminates early on in extranodal tissues. Although proliferation remains located in lymphoid organs only, suggesting a major role of the tumor ecosystem, few studies have assessed MCL microenvironment. We therefore cocultured primary circulating MCL cells from 21 patients several weeks ex vivo with stromal or lymphoid-like (CD40L) cells to determine which interactions could support their proliferation. We showed that coculture with lymphoid-like cells, but not stromal cells, induced cell-cycle progression, which was amplified by MCL-specific cytokines (insulin like growth factor-1, B-cell activating factor, interleukin-6, interleukin-10). Of interest, we showed that our model recapitulated the MCL in situ molecular signatures (ie, proliferation, NF-kappaB, and survival signatures). We further demonstrated that proliferating MCL harbored an imbalance in Bcl-2 family expression, leading to a consequent loss of mitochondrial priming. Of interest, this loss of priming was overcome by the type II anti-CD20 antibody obinutuzumab, which counteracted Bcl-xL induction through NF-kappaB inhibition. Finally, we showed that the mitochondrial priming directly correlated with the sensitivity toward venetoclax and alkylating drugs. By identifying the microenvironment as the major support for proliferation and drug resistance in MCL, our results highlight a selective approach to target the lymphoma niche.

PMID- 27697774 TI - Haploidentical hematopoietic transplantation for the cure of leukemia: from its biology to clinical translation. AB - The present review describes the biology of human leukocyte antigen haplotype mismatched ("haploidentical") transplantation, its translation to clinical practice to cure leukemia, and the results of current transplantation protocols. The 1990s saw what had been major drawbacks of haploidentical transplantation, ie, very strong host-versus-graft and graft-versus-host alloresponses, which led respectively to rejection and graft-versus-host disease (GVHD), being overcome through transplantation of a "mega-dose" of T cell-depleted peripheral blood hematopoietic progenitor cells and no posttransplant pharmacologic immunosuppression. The absence of posttransplant immunosuppression was an opportunity to discover natural killer cell alloreactions that eradicated acute myeloid leukemia and improved survival. Furthermore, it also unveiled the benefits of transplantation from mother donors, a likely consequence of the mother-to-child interaction during pregnancy. More recent transplantation protocols use unmanipulated (without ex vivo T-cell depletion) haploidentical grafts combined with enhanced posttransplant immunosuppression to help prevent GVHD. Unmanipulated grafts substantially extended the use of haploidentical transplantation with results than even rival those of matched hematopoietic transplantation. In T cell-depleted haploidentical transplantation, recent advances were made by the adoptive transfer of regulatory and conventional T cells. PMID- 27697775 TI - Strategies before, during, and after hematopoietic cell transplantation to improve T-cell immune reconstitution. AB - T-cell immune reconstitution (IR) after allogeneic hematopoietic cell transplantation (allo-HCT) is highly variable between patients and may take several months to even years. Patients with delayed or unbalanced T-cell IR have a higher probability of developing transplantation-related morbidity, mortality, and relapse of disease. Hence, there is a need for strategies to better predict and improve IR to reduce these limitations of allo-HCT. In this review, we provide an update of current and in-near-future clinically relevant strategies before, during, and after transplantation to achieve successful T-cell IR. Potent strategies are choosing the right HCT source (eg, donor-recipient matching, cell dose, graft manipulation), individualized conditioning and serotherapy (eg, antithymocyte globulin), nutritional status, exercise, home care, modulation of microbiota, enhancing homeostatic peripheral expansion, promoting thymopoiesis, and the use of adjuvant-targeted cellular immunotherapies. Strategies to prevent graft-versus-host disease are important as well because this complication and the subsequent need for immunosuppression affects T-cell IR and function. These options aim for personalized precision transplantation, where allo-HCT therapy is designed to boost a well-balanced T-cell IR and limit complications in individual patients, resulting in overall lower morbidity and higher survival chances.

PMID- 27697777 TI - Implication of external price referencing and parallel trade on pharmaceutical expenditure: indirect evidence from lower-income European countries. AB - External price referencing (EPR) is applied more and more frequently worldwide by payers to control pharmaceutical prices. Together with the parallel trade of pharmaceuticals, EPR may result in lower pharmaceutical prices in higher-income countries and higher prices in lower-income countries, which implies that pharmaceutical expenditure grows more rapidly in the latter than in the former group. Our objective was to assess this hypothesis. We used hierarchical linear models on country-level panel data to show that-after controlling for compounding factors such as GDP, the proportion of the old-age population or life expectancy the annual growth rate of pharmaceutical expenditure was 2.1% points larger in the lower- than in the higher-income members of the European Union between 2000 and 2008. This difference in trends became non-significant (0.6% points) after the onset of the global economic crisis. There was no significant difference between lower- and higher-income countries in the growth rate of non pharmaceutical health expenditure in either period. Our results indirectly support the presence of price convergence of pharmaceuticals among European countries, and EPR and parallel trade may provide a reasonable explanation to the observed trend difference of pharmaceutical expenditure in the two groups of countries between 2000 and 2008. This higher growth rate of pharmaceutical expenditure put extra burden on public health care budgets in lower-income countries and resulted in disproportionately more cost-containment measures compared to higher-income countries after 2008. It remains to be seen whether the disappearance of the difference in trend growth rates due to special health policy interventions in countries with economic difficulties is temporary or permanent. PMID- 27697778 TI - Aquatic Habits of Cetacean Ancestors: Integrating Bone Microanatomy and Stable Isotopes. AB - The earliest cetaceans were interpreted as semi-aquatic based on the presence of thickened bones and stable oxygen isotopes in tooth enamel. However, the origin of aquatic behaviors in cetacean relatives (e.g., raoellids, anthracotheres) remains unclear. This study reconstructs the origins of aquatic behaviors based on long bone microanatomy and stable oxygen isotopes of tooth enamel in modern and extinct cetartiodactylans. Our findings are congruent with published accounts that microanatomy can be a reliable indicator of aquatic behaviors in taxa that are obligatorily aquatic, and also highlight that some "semi-aquatic" behaviors (fleeing into the water to escape predation) may have a stronger relationship to bone microanatomy than others (herbivory in near-shore aquatic settings). Bone microanatomy is best considered with other lines of information in the land-to sea transition of cetaceans, such as stable isotopes. This study extends our understanding of the progression of skeletal phenotypes associated with habitat shifts in the relatives of cetaceans. PMID- 27697779 TI - Secondary Evolution of Aquatic Propulsion in Higher Vertebrates: Validation and Prospect. AB - Re-invasion of the aquatic environment by terrestrial vertebrates resulted in the evolution of species expressing a suite of adaptations for high-performance swimming. Examination of swimming by secondarily aquatic vertebrates provides opportunities to understand potential selection pressures and mechanical constraints, which may have directed the evolution of these aquatic species. Mammals and birds realigned the body and limbs for cursorial movements and flight, respectively, from the primitive tetrapod configuration. This realignment produced multiple solutions for aquatic specializations and swimming modes. Initially, in the evolution of aquatic mammals and birds, swimming was accomplished by using paired appendages in a low-efficiency, drag-based paddling mode. This mode of swimming arose from the modification of neuromotor patterns associated with gaits characteristic of terrestrial and aerial locomotion. The evolution of advanced swimming modes occurred in concert with changes in buoyancy control for submerged swimming, and a need for increased aquatic performance. Aquatic mammals evolved three specialized lift-based modes of swimming that included caudal oscillation, pectoral oscillation, and pelvic oscillation. Based on modern analogs, a biomechanical model was developed to explain the evolution of specialized aquatic mammals and their transitional forms. Subsequently, fossil aquatic mammals were described that validated much of the model. However, for birds, which were adapted for aerial flight, fossil evidence has been less forthcoming to explain the transition to aquatic capabilities. A biomechanical model is proposed for birds to describe the evolution of specialized lift-based foot and wing swimming. For both birds and mammals, convergence in morphology and propulsive mechanics is dictated by the need to increase speed, reduce drag, improve thrust output, enhance efficiency, and control maneuverability in the aquatic environment. PMID- 27697781 TI - Asymptomatic Intradialytic Supraventricular Arrhythmias and Adverse Outcomes in Patients on Hemodialysis. AB - BACKGROUND AND OBJECTIVES: Supraventricular arrhythmias are associated with high morbidity and mortality. Nevertheless, this condition has received little attention in patients on hemodialysis. The objective of this study was to analyze the incidence of intradialysis supraventricular arrhythmia and its long-term prognostic value. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We designed an observational and prospective study in a cohort of patients on hemodialysis with a 10-year follow-up period. All patients were recruited for study participation and were not recruited for clinical indications. The study population comprised 77 patients (42 men and 35 women; mean age =58+/-15 years old) with sinus rhythm monitored using a Holter electrocardiogram over six consecutive hemodialysis sessions at recruitment. RESULTS: Hypertension was present in 68.8% of patients, and diabetes was present in 29.9% of patients. Supraventricular arrhythmias were recorded in 38 patients (49.3%); all of these were short, asymptomatic, and self limiting. Age (hazard ratio, 1.04 per year; 95% confidence interval, 1.00 to 1.08) and right atrial enlargement (hazard ratio, 4.29; 95% confidence interval, 1.30 to 14.09) were associated with supraventricular arrhythmia in the multivariate analysis. During a median follow-up of 40 months, 57 patients died, and cardiovascular disease was the main cause of death (52.6%). The variables associated with all-cause mortality in the Cox model were age (hazard ratio, 1.04 per year; 95% confidence interval, 1.00 to 1.08), C-reactive protein (hazard ratio, 1.04 per 1 mg/L; 95% confidence interval, 1.00 to 1.08), and supraventricular arrhythmia (hazard ratio, 3.21; 95% confidence interval, 1.29 to 7.96). Patients with supraventricular arrhythmia also had a higher risk of nonfatal cardiovascular events (hazard ratio, 4.32; 95% confidence interval, 2.11 to 8.83) and symptomatic atrial fibrillation during follow-up (hazard ratio, 17.19; 95% confidence interval, 2.03 to 145.15). CONCLUSIONS: The incidence of intradialysis supraventricular arrhythmia was high in our hemodialysis study population. Supraventricular arrhythmias were short, asymptomatic, and self limiting, and although silent, these arrhythmias were independently associated with mortality and cardiovascular events. PMID- 27697782 TI - Glomerular Pathology in Dent Disease and Its Association with Kidney Function. AB - BACKGROUND AND OBJECTIVES: Dent disease is a rare X-linked disorder characterized by low molecular weight proteinuria and often considered a renal tubular disease. However, glomerulosclerosis was recently reported in several patients. Thus, Dent disease renal histopathologic features were characterized and assessed, and their association with kidney function was assessed. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Clinical renal pathology reports and slides (where available) were collected from 30 boys and men in eight countries who had undergone clinical renal biopsy between 1995 and 2014. RESULTS: Median (25th, 75th percentiles) age at biopsy was 7.5 (5, 19) years with an eGFR of 69 (44, 94) ml/min per 1.73 m2 and a 24-hour urine protein of 2000 (1325, 2936) mg. A repeat biopsy for steroid resistant proteinuria was performed in 13% (four of 30) of the patients. Prominent histologic findings included focal global glomerulosclerosis in 83% (25 of 30; affecting 16%+/-19% glomeruli), mild segmental foot process effacement in 57% (13 of 23), focal interstitial fibrosis in 60% (18 of 30), interstitial lymphocytic infiltration in 53% (16 of 30), and tubular damage in 70% (21 of 30). Higher percentages of globally sclerotic glomeruli, foot process effacement, and interstitial inflammation were associated with lower eGFR at biopsy, whereas foot process effacement was associated with steeper annual eGFR decline. CONCLUSIONS: These associations suggest a potential role for glomerular pathology, specifically involving the podocyte, in disease progression, which deserves further study. Furthermore, Dent disease should be suspected in boys and men who have unexplained proteinuria with focal global glomerulosclerosis and segmental foot process effacement on renal biopsy. PMID- 27697783 TI - Conservative Management and End-of-Life Care in an Australian Cohort with ESRD. AB - BACKGROUND AND OBJECTIVES: We aimed to determine the proportion of patients who switched to dialysis after confirmed plans for conservative care and compare survival and end-of-life care among patients choosing conservative care with those initiating RRT. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: A cohort study of 721 patients on incident dialysis, patients receiving transplants, and conservatively managed patients from 66 Australian renal units entered into the Patient Information about Options for Treatment Study from July 1 to September 30, 2009 were followed for 3 years. A two-sided binomial test assessed the proportion of patients who switched from conservative care to RRT. Cox regression, stratified by center and adjusted for patient and treatment characteristics, estimated factors associated with 3-year survival. RESULTS: In total, 102 of 721 patients planned for conservative care, and median age was 80 years old. Of these, 8% (95% confidence interval, 3% to 13%), switched to dialysis, predominantly for symptom management. Of 94 patients remaining on a conservative pathway, 18% were alive at 3 years. Of the total 721 patients, 247 (34%) died by study end. In multivariable analysis, factors associated with all cause mortality included older age (hazard ratio, 1.55; 95% confidence interval, 1.36 to 1.77), baseline serum albumin <3.0 versus 3.7-5.4 g/dl (hazard ratio, 4.31; 95% confidence interval, 2.72 to 6.81), and management with conservative care compared with RRT (hazard ratio, 2.18; 95% confidence interval, 1.39 to 3.40). Of 247 deaths, patients managed with RRT were less likely to receive specialist palliative care (26% versus 57%; P<0.001), more likely to die in the hospital (66% versus 42%; P<0.001) than home or hospice, and more likely to receive palliative care only within the last week of life (42% versus 15%; P<0.001) than those managed conservatively. CONCLUSIONS: Survival after 3 years of conservative management is common, with relatively few patients switching to dialysis. Specialist palliative care services are used more frequently and at an earlier time point for conservatively managed patients, a practice associated with better symptom management and quality of life. PMID- 27697785 TI - A flow cytometric method for estimating S-phase duration in plants. AB - The duration of the DNA synthesis stage (S phase) of the cell cycle is fundamental in our understanding of cell cycle kinetics, cell proliferation, and DNA replication timing programs. Most S-phase duration estimates that exist for plants are based on indirect measurements. We present a method for directly estimating S-phase duration by pulse-labeling root tips or actively dividing suspension cells with the halogenated thymidine analog 5-ethynl-2'-deoxyuridine (EdU) and analyzing the time course of replication with bivariate flow cytometry. The transition between G1 and G2 DNA contents can be followed by measuring the mean DNA content of EdU-labeled S-phase nuclei as a function of time after the labeling pulse. We applied this technique to intact root tips of maize (Zea mays L.), rice (Oryza sativa L.), barley (Hordeum vulgare L.), and wheat (Triticum aestivum L.), and to actively dividing cell cultures of Arabidopsis (Arabidopsis thaliana (L.) Heynh.) and rice. Estimates of S-phase duration in root tips were remarkably consistent, varying only by ~3-fold, although the genome sizes of the species analyzed varied >40-fold. PMID- 27697780 TI - The OncoArray Consortium: A Network for Understanding the Genetic Architecture of Common Cancers. AB - BACKGROUND: Common cancers develop through a multistep process often including inherited susceptibility. Collaboration among multiple institutions, and funding from multiple sources, has allowed the development of an inexpensive genotyping microarray, the OncoArray. The array includes a genome-wide backbone, comprising 230,000 SNPs tagging most common genetic variants, together with dense mapping of known susceptibility regions, rare variants from sequencing experiments, pharmacogenetic markers, and cancer-related traits. METHODS: The OncoArray can be genotyped using a novel technology developed by Illumina to facilitate efficient genotyping. The consortium developed standard approaches for selecting SNPs for study, for quality control of markers, and for ancestry analysis. The array was genotyped at selected sites and with prespecified replicate samples to permit evaluation of genotyping accuracy among centers and by ethnic background. RESULTS: The OncoArray consortium genotyped 447,705 samples. A total of 494,763 SNPs passed quality control steps with a sample success rate of 97% of the samples. Participating sites performed ancestry analysis using a common set of markers and a scoring algorithm based on principal components analysis. CONCLUSIONS: Results from these analyses will enable researchers to identify new susceptibility loci, perform fine-mapping of new or known loci associated with either single or multiple cancers, assess the degree of overlap in cancer causation and pleiotropic effects of loci that have been identified for disease specific risk, and jointly model genetic, environmental, and lifestyle-related exposures. IMPACT: Ongoing analyses will shed light on etiology and risk assessment for many types of cancer. Cancer Epidemiol Biomarkers Prev; 26(1); 126 35. (c)2016 AACR. PMID- 27697786 TI - Axillary buds are dwarfed shoots that tightly regulate GA pathway and GA inducible 1,3-beta-glucanase genes during branching in hybrid aspen. AB - Axillary buds (AXBs) of hybrid aspen (Populus tremula*P. tremuloides) contain a developing dwarfed shoot that becomes para-dormant at the bud maturation point. Para-dormant AXBs can grow out after stem decapitation, while dormant AXBs pre require long-term chilling to release them from dormancy. The latter is mediated by gibberellin (GA)-regulated 1,3-beta-glucanases, but it is unknown if GA is also important in the development, activation, and outgrowth of para-dormant AXBs. The present data show that para-dormant AXBs up-regulate GA receptor genes during their maturation, but curtail GA biosynthesis by down-regulating the rate limiting GIBBERELLIN 3-OXIDASE2 (GA3ox2), which is characteristically expressed in the growing apex. However, decapitation significantly up-regulated GA3ox2 and GA4-responsive 1,3-beta-glucanases (GH17-family; alpha-clade). In contrast, decapitation down-regulated gamma-clade 1,3-beta-glucanases, which were strongly up-regulated in maturing AXBs concomitant with lipid body accumulation. Overexpression of selected GH17 members in hybrid aspen resulted in characteristic branching patterns. The alpha-clade member induced an acropetal branching pattern, whereas the gamma-clade member activated AXBs in recurrent flushes during transient cessation of apex proliferation. The results support a model in which curtailing the final step in GA biosynthesis dwarfs the embryonic shoot, while high levels of GA precursors and GA receptors keep AXBs poised for growth. GA signaling, induced by decapitation, reinvigorates symplasmic supply routes through GA-inducible 1,3-beta-glucanases that hydrolyze callose at sieve plates and plasmodesmata. PMID- 27697788 TI - Challenges and perspectives in commercializing plastid transformation technology. AB - Plastid transformation has emerged as an alternative platform to generate transgenic plants. Attractive features of this technology include specific integration of transgenes-either individually or as operons-into the plastid genome through homologous recombination, the potential for high-level protein expression, and transgene containment because of the maternal inheritance of plastids. Several issues associated with nuclear transformation such as gene silencing, variable gene expression due to the Mendelian laws of inheritance, and epigenetic regulation have not been observed in the plastid genome. Plastid transformation has been successfully used for the production of therapeutics, vaccines, antigens, and commercial enzymes, and for engineering various agronomic traits including resistance to biotic and abiotic stresses. However, these demonstrations have usually focused on model systems such as tobacco, and the technology per se has not yet reached the market. Technical factors limiting this technology include the lack of efficient protocols for the transformation of cereals, poor transgene expression in non-green plastids, a limited number of selection markers, and the lengthy procedures required to recover fully segregated plants. This article discusses the technology of transforming the plastid genome, the positive and negative features compared with nuclear transformation, and the current challenges that need to be addressed for successful commercialization. PMID- 27697787 TI - Changes in the DNA methylation pattern of the host male gametophyte of viroid infected cucumber plants. AB - Eukaryotic organisms exposed to adverse conditions are required to show a certain degree of transcriptional plasticity in order to cope successfully with stress. Epigenetic regulation of the genome is a key regulatory mechanism allowing dynamic changes of the transcriptional status of the plant in response to stress. The Hop stunt viroid (HSVd) induces the demethylation of ribosomal RNA (rRNA) in cucumber (Cucumis sativus) leaves, leading to increasing transcription rates of rRNA. In addition to the clear alterations observed in vegetative tissues, HSVd infection is also associated with drastic changes in gametophyte development. To examine the basis of viroid-induced alterations in reproductive tissues, we analysed the cellular and molecular consequences of HSVd infection in the male gametophyte of cucumber plants. Our results indicate that in the pollen grain, accumulation of HSVd RNA induces a decondensation of the generative nucleus that correlates with a dynamic demethylation of repetitive regions in the cucumber genome that include rRNA genes and transposable elements (TEs). We therefore propose that HSVd infection impairs the epigenetic control of rRNA genes and TEs in gametic cells of cucumber, a phenomenon thus far unknown to occur in this reproductive tissue as a consequence of pathogen infection. PMID- 27697790 TI - Further clarity on cooperation and morality. AB - I explore the increasingly important issue of cooperation in immoral actions, particularly in connection with healthcare. Conscientious objection, especially as pertains to religious freedom in healthcare, has become a pressing issue in the light of the US Supreme Court judgement in Hobby Lobby Section 'Moral evaluation using the basic principles of cooperation' outlines a theory of cooperation inspired by Catholic moral theologians such as those cited by the court. The theory has independent plausibility and is at least worthy of serious consideration-in part because it is an instance of double-effect reasoning, which is also independently plausible despite its association with moral theology. Section 'Case study: Burwell v. Hobby Lobby' examines Hobby Lobby in detail. Even if the judgement was correct in that case the reasoning was not, as it involved applying a 'mere sincerity' test to the cooperation question. The mere sincerity test leads to absurd consequences, whereas a reasonableness test applied using the theory of cooperation defended here would avoid absurdity. Section 'A question of remoteness: "accommodations" and opt-outs' explores the post-Hobby Lobby problem further, examining opt-outs and accommodations: the Little Sisters of the Poor case shows how opt-outs are misunderstood on a mere sincerity test, which the court rightly rejected. Section 'Application to the medical field: Doogan and Wood' discusses the UK case of Doogan and Wood, concerning participation in abortion. Again, a judicially recognised ethic of cooperation, if it were part of the fabric of legal reasoning in such cases, would have enabled the conscientious objectors in this and similar situations to have their freedom of conscience and religion respected in a way that it currently is not. PMID- 27697789 TI - Spatial Regulation of ABCG25, an ABA Exporter, Is an Important Component of the Mechanism Controlling Cellular ABA Levels. AB - The phytohormone abscisic acid (ABA) plays crucial roles in various physiological processes, including responses to abiotic stresses, in plants. Recently, multiple ABA transporters were identified. The loss-of-function and gain-of-function mutants of these transporters show altered ABA sensitivity and stomata regulation, highlighting the importance of ABA transporters in ABA-mediated processes. However, how the activity of these transporters is regulated remains elusive. Here, we show that spatial regulation of ATP BINDING CASETTE G25 (ABCG25), an ABA exporter, is an important mechanism controlling its activity. ABCG25, as a soluble green fluorescent protein (sGFP) fusion, was subject to posttranslational regulation via clathrin-dependent and adaptor protein complex-2 dependent endocytosis followed by trafficking to the vacuole. The levels of sGFP:ABCG25 at the plasma membrane (PM) were regulated by abiotic stresses and exogenously applied ABA; PM-localized sGFP:ABCG25 decreased under abiotic stress conditions via activation of endocytosis in an ABA-independent manner, but increased upon application of exogenous ABA via activation of recycling from early endosomes in an ABA-dependent manner. Based on these findings, we propose that the spatial regulation of ABCG25 is an important component of the mechanism by which plants fine-tune cellular ABA levels according to cellular and environmental conditions. PMID- 27697792 TI - Cancer care in Romania: challenges and pitfalls of children's and adolescents' multifaceted involvement. AB - Communication about diagnosis and medical treatment for children suffering from life-threatening illnesses is complex. It is a primary step in involving underage patients and families in care and lays the foundation for obtaining parental permission and patient assent for treatment. In practice child participation in care is often difficult to obtain due to patients' different and sometimes fluctuating preferences, but also parents' protective strategies. Physicians may be susceptible to parental wishes to limit information and feel uncomfortable discussing issues related to uncertainty of cure with patients. A qualitative study in Romanian paediatric oncology units was conducted to explore children's involvement from the perspectives of parents and oncologists. Interviews with participants discussed 18 patient cases. Data were transcribed and thematic analysis was used to interpret and mine patients' involvement during treatment. Different facets of patient participation were identified: restricting, widening and enhancing involvement. A fourth category, unintentional involvement, occurred for all patients due to children's observations during long-term hospitalisations and access to Internet. Uncertainty overarched parental attitudes regarding the extent to which children should be included. Physicians usually complied with parental wishes to limit involvement, but together with parents involved patients at least in a practical way. Adults' protective attitude may backfire, as adolescents' online searches often expose patients to worse-case scenarios. Further research should acknowledge the hazards of restricted diagnosis disclosure and develop clinician tools to support families in communicating with patients. This should be paralleled by physician efforts to elicit patients' needs regarding participation. PMID- 27697791 TI - Victims, vectors and villains: are those who opt out of vaccination morally responsible for the deaths of others? AB - Mass vaccination has been a successful public health strategy for many contagious diseases. The immunity of the vaccinated also protects others who cannot be safely or effectively vaccinated-including infants and the immunosuppressed. When vaccination rates fall, diseases like measles can rapidly resurge in a population. Those who cannot be vaccinated for medical reasons are at the highest risk of severe disease and death. They thus may bear the burden of others' freedom to opt out of vaccination. It is often asked whether it is legitimate for states to adopt and enforce mandatory universal vaccination. Yet this neglects a related question: are those who opt out, where it is permitted, morally responsible when others are harmed or die as a result of their decision? In this article, we argue that individuals who opt out of vaccination are morally responsible for resultant harms to others. Using measles as our main example, we demonstrate the ways in which opting out of vaccination can result in a significant risk of harm and death to others, especially infants and the immunosuppressed. We argue that imposing these risks without good justification is blameworthy and examine ways of reaching a coherent understanding of individual moral responsibility for harms in the context of the collective action required for disease transmission. Finally, we consider several objections to this view, provide counterarguments and suggest morally permissible alternatives to mandatory universal vaccination including controlled infection, self-imposed social isolation and financial penalties for refusal to vaccinate.

PMID- 27697795 TI - Multilevel Small-Area Estimation of Multiple Cigarette Smoking Status Categories Using the 2012 Behavioral Risk Factor Surveillance System. AB - BACKGROUND: Smoking is the leading preventable cause of death; however, small area estimates for detailed smoking status are limited. We developed multilevel small-area estimate mixed models to generate county-level estimates for six smoking status categories: current, some days, every day, former, ever, and never. METHOD: Using 2012 Behavioral Risk Factor Surveillance System (BRFSS) data (our sample size = 405,233 persons), we constructed and fitted a series of multilevel logistic regression models and applied them to the U.S. Census population to generate county-level prevalence estimates. We mapped the estimates by sex and aggregated them into state and national estimates. We conducted comparisons for internal consistency with BRFSS states' estimates using Pearson correlation coefficients, and external validation with the 2012 National Health Interview Survey current smoking prevalence. RESULTS: Correlation coefficients ranged from 0.908 to 0.982, indicating high internal consistency. External validation indicated complete agreement (prevalence = 18.06%). We found large variations in current and former smoking status between and within states and by sex. County prevalence of former smokers was highest among men in the Northeast, North, and West. Utah consistently had the lowest smoking prevalence. CONCLUSIONS: Our models, which include demographic and geographic characteristics, provide reliable estimates that can be applied to multiple category outcomes and any demographic group. County and state estimates may help understand the variation in smoking prevalence in the United States and provide information for control and prevention. IMPACT: Detailed county and state smoking category estimates can help identify areas in need of tobacco control and prevention and potentially allow planning for health care.

AB - Multimorbidity, the presence of two or more chronic conditions in an individual, presents a major challenge for meeting the health care needs of older adults. This study advances understanding of multiple chronic conditions by using local colocation quotients to reveal spatial associations for five chronic conditions (arthritis, diabetes, heart disease, hypertension, and pulmonary disease) in a statewide panel of older adults in New Jersey. Among adults with three or more conditions, large concentrations of Arthritis-Heart Disease-Pulmonary Disease, Arthritis-Hypertension-Pulmonary Disease, and Diabetes-Heart Disease-Hypertension were observed, each triad located in different regions of the state. Individuals with other triads of conditions, in contrast, were distributed among all older adults in the sample as expected with no areas of local concentration. The study provides gerontologists with a new and effective method for uncovering geographical patterns in combinations of chronic conditions among the populations they serve, thereby enabling more effective interventions.

PMID- 27697799 TI - Audit of a tertiary heart failure outpatient service to assess compliance with NICE guidelines. AB - The National Institute for Health and Care Excellence (NICE) updated its guidelines for chronic heart failure (HF) in 2010. This re-audit assessed interim improvement as compared with an audit in 2011. Patients with HF (preserved and reduced ejection fraction) attending a tertiary cardiac centre over a 2-year period (January 2013-December 2014) were audited. The data collected included demographics, HF aetiology, medications, clinical parameters and cardiac rehabilitation. In total, 513 patients were audited. Compared with 2011, male preponderance (71%) and age (68+/-14 years, (Mean +/- SD)) were similar. 73% of patients lived outside of London. HF aetiologies included ischaemic heart disease (37% versus 40% in 2011), dilated cardiomyopathy (26% versus 20%) primary valve disease (13% versus 12%). For patients with left ventricular systolic dysfunction (n=434, 85% of patients audited) 89% were taking beta-blockers (compared with 77% in 2011), 91% an angiotensin converting enzyme inhibitor or angiotensin receptor blocker (86% in 2011) and 56% a mineralocorticoid receptor antagonist (44% in 2011); 6% were prescribed ivabradine. All patients were reviewed at least 6 monthly. Although 100% of patients were educated about exercise, only 21 (4%) enrolled in a supervised exercise programme. This audit demonstrated high rates of documentation, follow-up and compliance with guideline-based medical therapies. A consistent finding was poor access to cardiac rehabilitation. PMID- 27697800 TI - Iatrogenic Cushing's syndrome due to drug interaction between glucocorticoids and the ritonavir or cobicistat containing HIV therapies. AB - Ritonavir and cobicistat, used as pharmacokinetic enhancers in combination with some antiretrovirals (ARVs) for the treatment of HIV, are potent inhibitors of the CYP3A4 isoenzyme. Most glucocorticoids are metabolised via the CYP3A4 pathway and iatrogenic Cushing's syndrome (ICS), with possible secondary adrenal insufficiency (SAI), is a recognised complication following co-administration with ritonavir or cobicistat. A structured approach for identifying and managing potentially affected individuals has not been established.We systematically identified patients with ICS/SAI and found substantial heterogeneity in clinical practice across three large London HIV centres. While this significant drug interaction and its complications are now well-recognised, it is apparent that there is no standardised approach to management or guidance for the general physician. Here we describe the management of ICS/SAI in our current practice, review the available evidence and suggest practice recommendations. PMID- 27697801 TI - The effect of ivabradine on functional capacity in patients with chronic obstructive pulmonary disease. AB - Increased sympathetic tone and use of bronchodilators increase heart rate and this may worsen functional capacity in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to look at the short-term effect of the heart rate lowering drug ivabradine on clinical status in COPD patients.We randomised 80 COPD patients with sinus heart rate >=90 bpm into either taking ivabradine 7.5 mg twice per day or placebo for two weeks. We assessed all patients using the modified Borg scale and 6-minute walk test at baseline and then again 2 weeks after randomisation.There were no significant differences in age, sex, severity of airway obstruction (measured using forceful exhalation), severity of diastolic dysfunction or pulmonary artery systolic pressure between the two groups. The ivabradine group showed significant improvement in 6-minute walk distance (from 192.6+/-108.8 m at baseline to 285.1+/-88.9 m at the end of the study) compared with the control group (230.6+/ 68.4 at baseline and 250.4+/-65.8 m at the end of study) (p<0.001). This improvement in the drug group was associated with significant improvement of dyspnea on modified Borg scale (p=0.007).Lowering heart rate with ivabradine can improve exercise capacity and functional class in COPD patients with resting heart rate >90 bpm. PMID- 27697802 TI - Stroke mimic diagnoses presenting to a hyperacute stroke unit. AB - Stroke services have been centralised in several countries in recent years. Diagnosing acute stroke is challenging and a high proportion of patients admitted to stroke units are diagnosed as a non-stroke condition (stroke mimics). This study aims to describe the stroke mimic patient group, including their impact on stroke services. We analysed routine clinical data from 2,305 consecutive admissions to a stroke unit at St George's Hospital, London. Mimic groupings were derived from 335 individual codes into 17 groupings. From 2,305 admissions, 555 stroke mimic diagnoses were identified (24.2%) and 72% of stroke mimics had at least one stroke risk factor. Common mimic diagnoses were headache, seizure and syncope. Medically unexplained symptoms and decompensation of underlying conditions were also common. Median length of stay was 1 day; a diagnosis of dementia (p=0.028) or needing MRI (p=0.006) was associated with a longer stay. Despite emergency department assessment by specialist clinicians and computed tomography brain, one in four suspected stroke patients admitted to hospital had a non-stroke diagnosis. Stroke mimics represent a heterogeneous patient group with significant impacts on stroke services. Co-location of stroke and acute neurology services may offer advantages where service reorganisation is being considered. PMID- 27697803 TI - Where did the acute medical trainees go? A review of the career pathways of acute care common stem acute medical trainees in London. AB - Acute care common stem acute medicine (ACCS AM) training was designed to develop competent multi-skilled acute physicians to manage patients with multimorbidity from 'door to discharge' in an era of increasing acute hospital admissions. Recent surveys by the Royal College of Physicians have suggested that acute medical specialties are proving less attractive to trainees. However, data on the career pathways taken by trainees completing core acute medical training has been lacking. Using London as a region with a 100% fill rate for its ACCS AM training programme, this study showed only 14% of trainees go on to higher specialty training in acute internal medicine and a further 10% to pursue higher medical specialty training with dual accreditation with internal medicine. 16% of trainees switched from ACCS AM to emergency medicine or anaesthetics during core ACCS training, and intensive care medicine proved to be the most popular career choice for ACCS AM trainees (21%). The ACCS AM training programme therefore does not appear to be providing what it was set out to do and this paper discusses the potential causes and effects. PMID- 27697804 TI - Haemophagocytic lymphohistiocytosis: an elusive syndrome. AB - Haemophagocytic lymphohistiocytosis is a rare inflammatory condition. It can present in adult general medical patients and is a challenging diagnostic conundrum. This article provides an overview of the pathophysiology and clinical presentation of the syndrome for the general physician who will be rarely confronted with this problem but will have to act promptly when the situation arises. Treatment is also briefly discussed, although this usually occurs in a specialist setting after the diagnosis has been established. PMID- 27697805 TI - The health impacts of the refugee crisis: a medical charity perspective. AB - Over the last year, hundreds of thousands of refugees fleeing war and persecution have travelled from the Middle East to Europe. Arduous journeys and poor living conditions are causing myriad health problems and access to basic healthcare is extremely limited for those on the move. At every stage of the journey, people are suffering, including after they settle in Europe. The difficulty in managing non-communicable diseases means that some refugees are not getting the treatment they need, which in the long term can have a significant adverse impact on their health. Pregnant women are frequently unable to access antenatal care in Europe and the vaccination rate for refugee children is worrying low. Those who have suffered traumatic experiences in their home country are highly susceptible to developing psychological problems; an issue compounded by poverty, their displacement and being victims of violence. PMID- 27697806 TI - Drug therapies in type 2 diabetes: an era of personalised medicine. AB - Optimal management of diabetes involves a multidisciplinary approach. Prioritisation of lifestyle change, blood pressure and lipid control, and regular screening for complications are advocated in most international guidelines. Good glucose control, however, remains an important aim of treatment, although it is increasingly recognised that glucose targets should be individualised, with less stringent targets for older patients with significant comorbidities.In recent years, a number of newer therapies for hyperglycaemia have become available. This review aims to discuss currently available options for patients with type 2 diabetes, and also discusses potential new therapies that may be on the horizon in the future. PMID- 27697807 TI - How to succeed as a junior doctor. AB - The Royal College of Physicians (RCP) organised an inaugural 1-day conference, the aim of which was to look into some of the key issues that junior doctors need to address when beginning their careers. The target audience was medical students but a few foundation doctors were also in attendance. The conference also helped to increase RCP engagement with medical students and foundation doctors. The day was co-chaired by Professor Kate Thomas (vice dean, University of Birmingham) and Dr Andrew Macleod and Dr Kanwaljit Sandhu (RCP regional advisors for the West Midlands).

AB - We present the case of a man with a history of migraines treated with propanolol, referred with a rash, diarrhoea, vomiting and hypotension. Our case highlights how prior beta-blocker use may prolong anaphylaxis and cause refractory hypotension. PMID- 27697809 TI - An extreme case of platypnoea-orthodeoxia syndrome. AB - An 80-year-old female presented with progressive breathlessness, worse on sitting or standing and relieved by lying flat. Subsequent investigations identified a patent foramen ovale (PFO) with right-to-left flow across the interatrial septum (IAS). A diagnosis of platypnoea orthodeoxia syndrome secondary to inter-atrial shunting was made. Technical features precluded a percutaneous PFO closure so an open surgical repair was performed with complete resolution of symptoms. We discuss the pathophysiology and management of platypnoea orthodeoxia syndrome. PMID- 27697810 TI - Sarcopenia and frailty: new challenges for clinical practice. AB - Sarcopenia and frailty are important conditions that become increasingly prevalent with age. Sarcopenia is the loss of muscle mass and function, and frailty can be defined as multi-system impairment associated with increased vulnerability to stressors. There is overlap between the two conditions, especially in terms of the physical aspects of the frailty phenotype: low grip strength, gait speed and muscle mass. These measures have been associated with a wide range of ageing outcomes and can be assessed in the clinical setting. In terms of intervention, there is evidence for the benefit of resistance exercise programmes, although these may not always be feasible. Considerable research into the use of medicines, both existing and new, as well as dietary supplements is ongoing. Finally in order to prevent or delay the development of these conditions, an additional approach is to consider aetiological factors operating across the life course. PMID- 27697811 TI - Rational prescribing: the principles of drug selection. AB - Prescribing is the most important tool used by physicians to cure illness, relieve symptoms and prevent future disease. It is also a complex intellectual task that requires formulation of an appropriate treatment regimen from the many thousands available, taking into account the infinite variation in the patients they encounter. Unfortunately, the selection of a medicine and dosage regimen is sometimes suboptimal, leading to poor patient outcomes (eg treatment failure, avoidable adverse reactions). This article will highlight some of the common prescribing errors and will develop a rational approach that includes making a diagnosis, estimating prognosis, establishing the goals of therapy, selecting the most appropriate treatment and monitoring the effects of the treatment. PMID- 27697812 TI - The epidemiology of polypharmacy. AB - Polypharmacy describes, in simplistic terms, the use of multiple medications in an individual. It has become a normal aspect of modern medicine, driven by an ageing, multimorbid population, the increasing availability of preventative medications and an increasing use of single-disease guidelines and adherence to evidence-based practice. However, polypharmacy is also associated with a range of adverse outcomes, and is considered an important and increasing challenge for clinical practice. Here, we consider the definitions of polypharmacy, the extent and nature of medication use in different settings, and the type of problems encountered as a consequence of polypharmacy. PMID- 27697813 TI - The need for a prescribing competency framework to address the burden of complex polypharmacy among multiple long-term conditions. AB - The original requirement for a competency framework for prescribers was to identify the essential skills for non-medical prescribers. However, core prescribing competencies are relevant to any prescriber. The new, revised version is especially relevant for doctors/physicians. Doctors are the most frequent prescribers - prescribing is the most common therapeutic intervention. The quantity and complexity of medicine use is increasing through multiple treatment strategies/pathways for multiple comorbidities, resulting in polypharmacy - especially with long-term conditions. This is against a background of the ongoing introduction of new drugs with novel mechanisms of action with increased risks of adverse effects, compounded by drug-drug and disease-drug interactions. This has increased the need for monitoring and follow-up, including identification and management of poor adherence. It is challenging for doctors to maintain safe and effective prescribing and train other doctors and non-medical prescribers within the multidisciplinary team. The prescribing competency framework provides a systematic approach to support doctors to prescribe safely and effectively. It can be used by medical schools to teach prescribing, including preparation for the prescribing safety assessment; by F1/F2 doctors to support prescribing in early years; as part of prescribing quality improvement initiatives and as a continuing professional development framework in general practice or acute care settings. PMID- 27697814 TI - European drug market entries 2015 with new mechanisms of action. AB - In this article, we consider the new drugs approved for the European market in 2015. We present a summary of the new mechanisms of action introduced and highlight three new mechanisms of action with a potentially high future impact: PCSK9 inhibition (alirocumab (Praluent(r)) and evolocumab (Repatha(r))) for hypercholesterolaemia, neprilysin inhibition (sacubitril in combination with valsartan (Entresto(r))) for heart failure, and interleukin-5 inhibition (mepolizumab (Nucala(r))) for asthma. PMID- 27697815 TI - Adverse drug reactions. AB - Adverse drug reactions (ADRs) remain a challenge in modern healthcare, particularly given the increasing complexity of therapeutics, an ageing population and rising multimorbidity.

PMID- 27697817 TI - Lesson of the month 1: Autoinflammatory syndromes - an unusual cause of pyrexia of unknown origin. AB - Autoinflammatory diseases are disorders of innate immunity and are characterised by recurring and unprovoked episodes of inflammation.

He was eventually diagnosed with hyperimmunoglobulinaemia D syndrome (HIDS); one of the autoinflammatory syndromes. PMID- 27697818 TI - Lesson of the month 2: An easily missed cause of confusion. AB - We describe the case of an 85-year-old woman who developed acute confusion, acute kidney injury and temperature spikes while on extended courses of beta-lactams for osteomyelitis. The cause of her deterioration was felt to be due to sepsis when in fact it was as a result of toxicity from antibiotics. This was demonstrated by a rapid resolution in her condition following haemodialysis. We also performed a literature review to appraise the neuro and nephrotoxicity of various antibiotics and how best to manage toxicity when it occurs.

PMID- 27697823 TI - Ultraviolet-Visible (UV-Vis) Microspectroscopic System Designed for the In Situ Characterization of the Dehydrogenation Reaction Over Platinum Supported Catalytic Microchannel Reactor. AB - An ultraviolet visible (UV-Vis) microspectroscopic system was designed for the in situ characterization of the activity of the silica supported platinum (Pt) catalyst toward the dehydrogenation of 1-methyl-1,4-cyclohexadiene carried out in a custom-designed catalytic microreactor cell. The in situ catalytic microreactor cell (ICMC) with inlet/outlet ports was prepared using quartz cover as the optical window to facilitate UV-Vis observation. A fabricated thermometric stage was adapted to the UV-Vis microspectrophotometer to control the reaction temperature inside the ICMC. The spectra were collected by focusing the UV-Vis beam on a 30 * 30 um area at the center of ICMC. At 393 K, the sequential measurement of the spectra recorded during the reaction exhibited a broad absorption peak with maximum absorbance at 260 nm that is characteristic for gaseous toluene. This result indicates that the silica supported Pt catalyst is active towards the dehydrogenation of 1-methyl-1,4-cyclohexadiene at the given experimental conditions. The onset of coke formation was also detected based on the appearance of absorption bands at 300 nm. The UV-Vis microspectroscopic system developed can be used further in studying the mechanism of the dehydrogenation reaction. PMID- 27697824 TI - The effectiveness of exercise therapy for temporomandibular dysfunction: a systematic review and meta-analysis. AB - OBJECTIVE: To investigate the effectiveness of exercise therapy on pain, function, and mobility outcomes in patients with temporomandibular joint dysfunction. STUDY DESIGN: Systematic review with meta-analysis. METHODS: A systematic review and meta-analysis undertaken following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that met the inclusion criteria: (1) randomized controlled trials; (2) a population with the diagnosis of temporomandibular joint dysfunction; and (3) interventions that included exercise therapy were considered for review. When studies demonstrated homogeneity on outcome measures, the mean differences or standardized mean differences with 95% confidence interval were calculated and pooled in a meta analysis for pooled synthesis. RESULTS: Six articles with a total of 419 participants were included in the review and only four studies were included in the meta-analysis. Mobility and mixed exercise therapy approaches appear to be the most common exercise approaches utilized for management of temporomandibular joint dysfunction. Exercise therapy and the associated dosage provide moderate short-term and varying long-term benefits in reduction of pain and improvement of range of motion of the in patients with temporomandibular joint dysfunction. CONCLUSION: Included studies suggest a mobility or a mixed approach to exercise therapies have impact on reducing pain, significant impact for increasing range of motion, but lack a significant impact for functional improvement. LEVEL OF EVIDENCE: Therapy, level 1a-. PMID- 27697822 TI - Notch-Mediated Epigenetic Regulation of Voltage-Gated Potassium Currents. AB - RATIONALE: Ventricular arrhythmias often arise from the Purkinje-myocyte junction and are a leading cause of sudden cardiac death. Notch activation reprograms cardiac myocytes to an induced Purkinje-like state characterized by prolonged action potential duration and expression of Purkinje-enriched genes. OBJECTIVE: To understand the mechanism by which canonical Notch signaling causes action potential prolongation. METHODS AND RESULTS: We find that endogenous Purkinje cells have reduced peak K+ current, Ito, and IK,slow when compared with ventricular myocytes. Consistent with partial reprogramming toward a Purkinje like phenotype, Notch activation decreases peak outward K+ current density, as well as the outward K+ current components Ito,f and IK,slow. Gene expression studies in Notch-activated ventricles demonstrate upregulation of Purkinje enriched genes Contactin-2 and Scn5a and downregulation of K+ channel subunit genes that contribute to Ito,f and IK,slow. In contrast, inactivation of Notch signaling results in increased cell size commensurate with increased K+ current amplitudes and mimics physiological hypertrophy. Notch-induced changes in K+ current density are regulated at least in part via transcriptional changes. Chromatin immunoprecipitation demonstrates dynamic RBP-J (recombination signal binding protein for immunoglobulin kappa J region) binding and loss of active histone marks on K+ channel subunit promoters with Notch activation, and similar transcriptional and epigenetic changes occur in a heart failure model. Interestingly, there is a differential response in Notch target gene expression and cellular electrophysiology in left versus right ventricular cardiac myocytes. CONCLUSIONS: In summary, these findings demonstrate a novel mechanism for regulation of voltage-gated potassium currents in the setting of cardiac pathology and may provide a novel target for arrhythmia drug design. PMID- 27697825 TI - Current perspectives on the families of glycoside hydrolases of Mycobacterium tuberculosis: their importance and prospects for assigning function to unknowns. AB - Glycoside hydrolases (GHs) are enzymes that catalyze the hydrolysis of glycosidic bonds in glycoconjugates, oligo- and polysaccharides. A classification of these enzymes based on conserved sequence and structure motifs supported by the Carbohydrate Active Enzyme (CAZy) database has proven useful in the systematic groupings of similar enzymes into families. The human pathogen Mycobacterium tuberculosis employs 30 GHs to perform a variety of different functions, which can be divided into four broad categories: alpha-glucan metabolism, peptidoglycan remodeling, beta-glycan hydrolysis and alpha-demannosylation. The review presented here shows how the GHs that have been characterized play a role in each category. Expanding the genomic analysis of GH presence to other Mycobacterium species has highlighted the importance of certain families-most notably GH13 and GH23-in the general genomic make-up of mycobacteria. Since many GHs are still uncharacterized and considered as "conserved hypothetical" proteins, the grouping of them into respective families provides a strong prediction on their putative biological functions.

Early recognition of the patients at risk of MODS would be helpful in providing timely management and reducing the mortality. In all, 449 children with scrub typhus were enrolled at three hospitals in Yunnan, China from January 2010 to January 2015. The patients' clinical status of organ system dysfunction was evaluated on the day of discharge from hospital by using standard criteria. The patients were classified into MODS present (64 cases, 14.3%) or MODS absent (385 cases, 85.7%). Multivariate logistic regression analyses revealed that the prognostic factors for MODS included skin rash (odds ratio, OR = 3.3, p = 0.037), time interval form treatment to defervescence (OR = 1.2, p = 0.035), hemoglobin (OR = 0.54, p = 0.041), platelet counts (OR = 0.06, p < 0.001), aspartate-aminotransferase (OR = 4.7, p = 0.011) and total bilirubin (OR = 2.3, p = 0.013). By describing risk factors resulting in MODS in pediatric scrub typhus, our study provides clinicians with important information to improve the clinical monitoring and prognostication of MODS. PMID- 27697829 TI - Timing of Circumcision and Breastfeeding Initiation Among Newborn Boys. AB - BACKGROUND AND OBJECTIVES: Newborn circumcision, particularly in the first 24 hours of life, has been thought to adversely affect breastfeeding initiation. However, no studies specifically support an association between early circumcision and difficulty with breastfeeding initiation or maintenance. This study was designed to determine whether timing of newborn circumcision affects rates of exclusive breastfeeding during the first 2 weeks of life. METHODS: A retrospective study of 797 newborn boys and their mothers was conducted at a large military hospital. Exclusion criteria included gestational age <38 weeks, multiple delivery, NICU admission, and absence of maternal intention to breastfeed. Multivariable logistic regression models examined the relationship between time of elective circumcision and exclusive breastfeeding at 3 time points: hospital discharge and the newborn and 2-week outpatient visits. RESULTS: Mean infant age at circumcision was 29.7 hours. Thirty-one percent were circumcised at <24 hours of age. Rates of exclusive breastfeeding were 66.8%, 64.1%, and 63.7% at hospital discharge and the newborn and 2-week outpatient visits, respectively. In the multivariable model, time of circumcision was not significantly associated with exclusive breastfeeding at hospital discharge (odds ratio [OR], 1.01; 95% confidence interval [CI], 0.99-1.00; P = .54), the newborn outpatient visit (OR, 1.00; 95% CI, 0.99-1.02; P = .84), or the 2-week outpatient visit (OR, 0.99; 95% CI 0.98-1.01; P = .44). CONCLUSIONS: There was no significant association between timing of elective newborn circumcision and exclusive breastfeeding in the first 2 weeks of life. In this setting, early circumcision of otherwise healthy, term boys had no deleterious effects on breastfeeding initiation or maintenance. PMID- 27697830 TI - Erratum.

AB - OBJECTIVE: To assess if violent deaths were associated with pay days in Guatemala. DESIGN: Interrupted time series analysis. SETTING: Guatemalan national autopsy databases. PARTICIPANTS: Daily violence-related autopsy data for 22 418 decedents from 2009 to 2012. Data were provided by the Guatemalan National Institute of Forensic Sciences. Multiple pay-day lags and other important days such as holidays were tested. OUTCOME MEASURES: Absolute and relative estimates of excess violent deaths on pay days and holidays. RESULTS: The occurrence of violent deaths was not associated with pay days. However, a significant association was observed for national holidays, and this association was more pronounced when national holidays and pay days occurred simultaneously. This effect was observed mainly in males, who constituted the vast majority of violent deaths in Guatemala. An estimated 112 (coefficient=3.12; 95% CI 2.15 to 4.08; p<0.01) more male violent deaths occurred on holidays than were expected. An estimated 121 (coefficient=4.64; 95% CI 3.41 to 5.88; p<0.01) more male violent deaths than expected occurred on holidays that coincided with the first 2 days following a pay day. CONCLUSIONS: Men in Guatemala experience violent deaths at an elevated rate when pay days coincide with national holidays. Efforts to be better prepared for violence during national holidays and to prevent violent deaths by rescheduling pay days when these days co-occur with national holidays should be considered.

PMID- 27697832 TI - Rad51 and Rad54 promote noncrossover recombination between centromere repeats on the same chromatid to prevent isochromosome formation. AB - Centromeres consist of DNA repeats in many eukaryotes. Non-allelic homologous recombination (HR) between them can result in gross chromosomal rearrangements (GCRs). In fission yeast, Rad51 suppresses isochromosome formation that occurs between inverted repeats in the centromere. However, how the HR enzyme prevents homology-mediated GCRs remains unclear. Here, we provide evidence that Rad51 with the aid of the Swi/Snf-type motor protein Rad54 promotes non-crossover recombination between centromere repeats to prevent isochromosome formation. Mutations in Rad51 and Rad54 epistatically increased the rates of isochromosome formation and chromosome loss. In sharp contrast, these mutations decreased gene conversion between inverted repeats in the centromere. Remarkably, analysis of recombinant DNAs revealed that rad51 and rad54 increase the proportion of crossovers. In the absence of Rad51, deletion of the structure-specific endonuclease Mus81 decreased both crossovers and isochromosomes, while the cdc27/pol32-D1 mutation, which impairs break-induced replication, did not. We propose that Rad51 and Rad54 promote non-crossover recombination between centromere repeats on the same chromatid, thereby suppressing crossover between non-allelic repeats on sister chromatids that leads to chromosomal rearrangements. Furthermore, we found that Rad51 and Rad54 are required for gene silencing in centromeres, suggesting that HR also plays a role in the structure and function of centromeres. PMID- 27697833 TI - UNG protects B cells from AID-induced telomere loss. AB - Activation-induced deaminase (AID) initiates antibody gene diversification by creating G:U mismatches in the immunoglobulin loci. However, AID also deaminates nonimmunoglobulin genes, and failure to faithfully repair these off-target lesions can cause B cell lymphoma. In this study, we identify a mechanism by which processing of G:U produced by AID at the telomeres can eliminate B cells at risk of genomic instability. We show that telomeres are off-target substrates of AID and that B cell proliferation depends on protective repair by uracil-DNA glycosylase (UNG). In contrast, in the absence of UNG activity, deleterious processing by mismatch repair leads to telomere loss and defective cell proliferation. Indeed, we show that UNG deficiency reduces B cell clonal expansion in the germinal center in mice and blocks the proliferation of tumor B cells expressing AID. We propose that AID-induced damage at telomeres acts as a fail-safe mechanism to limit the tumor promoting activity of AID when it overwhelms uracil excision repair. PMID- 27697834 TI - Tumor macrophages are pivotal constructors of tumor collagenous matrix. AB - Tumor-associated macrophages (TAMs) promote tumor development, invasion, and dissemination by various mechanisms. In this study, using an orthotopic colorectal cancer (CRC) model, we found that monocyte-derived TAMs advance tumor development by the remodeling of its extracellular matrix (ECM) composition and structure. Unbiased transcriptomic and proteomic analyses of (a) TAM-abundant and -deficient tumor tissues and (b) sorted tumor-associated and -resident colonic macrophage subpopulations defined a distinct TAM-induced ECM molecular signature composed of an ensemble of matricellular proteins and remodeling enzymes they provide to the tumor microenvironment. Remarkably, many of these ECM proteins are specifically increased in human CRC versus healthy colon. Specifically, we demonstrate that although differentiating into TAMs, monocytes up-regulate matrix remodeling programs associated with the synthesis and assembly of collagenous ECM, specifically collagen types I, VI, and XIV. This finding was further established by advanced imaging showing that TAMs instruct the deposition, cross linking, and linearization of collagen fibers during tumor development, especially at areas of tumor invasiveness. Finally, we show that cancer associated fibroblasts are significantly outnumbered by TAMs in this model and that their expression of collagen XIV and I is reduced by TAM deficiency. Here, we outline a novel TAM protumoral function associated with building of the collagenous ECM niche. PMID- 27697835 TI - Complement pathway amplifies caspase-11-dependent cell death and endotoxin induced sepsis severity. AB - Cell death and release of proinflammatory mediators contribute to mortality during sepsis. Specifically, caspase-11-dependent cell death contributes to pathology and decreases in survival time in sepsis models. Priming of the host cell, through TLR4 and interferon receptors, induces caspase-11 expression, and cytosolic LPS directly stimulates caspase-11 activation, promoting the release of proinflammatory cytokines through pyroptosis and caspase-1 activation. Using a CRISPR-Cas9-mediated genome-wide screen, we identified novel mediators of caspase 11-dependent cell death. We found a complement-related peptidase, carboxypeptidase B1 (Cpb1), to be required for caspase-11 gene expression and subsequent caspase-11-dependent cell death. Cpb1 modifies a cleavage product of C3, which binds to and activates C3aR, and then modulates innate immune signaling. We find the Cpb1-C3-C3aR pathway induces caspase-11 expression through amplification of MAPK activity downstream of TLR4 and Ifnar activation, and mediates severity of LPS-induced sepsis (endotoxemia) and disease outcome in mice. We show C3aR is required for up-regulation of caspase-11 orthologues, caspase-4 and -5, in primary human macrophages during inflammation and that c3aR1 and caspase-5 transcripts are highly expressed in patients with severe sepsis; thus, suggesting that these pathways are important in human sepsis. Our results highlight a novel role for complement and the Cpb1-C3-C3aR pathway in proinflammatory signaling, caspase-11 cell death, and sepsis severity. PMID- 27697838 TI - Estimation after blinded sample size reassessment. AB - Blinded sample size reassessment is a popular means to control the power in clinical trials if no reliable information on nuisance parameters is available in the planning phase. We investigate how sample size reassessment based on blinded interim data affects the properties of point estimates and confidence intervals for parallel group superiority trials comparing the means of a normal endpoint. We evaluate the properties of two standard reassessment rules that are based on the sample size formula of the z-test, derive the worst case reassessment rule that maximizes the absolute mean bias and obtain an upper bound for the mean bias of the treatment effect estimate. PMID- 27697837 TI - NFATC3 promotes IRF7 transcriptional activity in plasmacy--toid dendritic cells. AB - Plasmacytoid dendritic cells (pDCs) rapidly produce large amounts of type 1 interferon (IFN) after Toll-like receptor 7 and 9 engagements. This specialized function of type 1 IFN production is directly linked to the constitutive expression of IRF7, the master transcription factor for type 1 IFN production. However, the IRF7 regulatory network in pDCs remains largely unknown. In this study, we identify that the transcription factor NFATC3 specifically binds to IRF7 and enhances IRF7-mediated IFN production. Furthermore, knockout of NFATC3 greatly reduced the CpG DNA-induced nuclear translocation of IRF7, which resulted in impaired type 1 IFN production in vitro and in vivo. In addition, we found that NFATC3 and IRF7 both bound to type 1 IFN promoters and that the NFAT binding site in IFN promoters was required for IRF7-mediated IFN expression. Collectively, our study shows that the transcription factor NFATC3 binds to IRF7 and functions synergistically to enhance IRF7-mediated IFN expression in pDCs. PMID- 27697839 TI - Heparan Sulfate Regulates the Structure and Function of Osteoprotegerin in Osteoclastogenesis. AB - Osteoprotegerin (OPG), a decoy receptor secreted by osteoblasts, is a major negative regulator of bone resorption. It functions by neutralizing the receptor activator of nuclear factor kappaB ligand (RANKL), which plays a central role in promoting osteoclastogenesis. OPG is known to be a high-affinity heparan sulfate (HS)-binding protein. Presumably, HS could regulate the function of OPG and affect how it inhibits RANKL. However, the molecular detail of HS-OPG interaction remains poorly understood, which hinders our understanding of how HS functions in osteoclastogenesis. Here we report mapping of the HS-binding site of OPG. The HS binding site, identified by mutagenesis study, consists of eight basic residues that are located mostly at the junction of the second death domain and the C terminal domain. We further show that heparin-derived dodecasaccharide is able to induce dimerization of OPG monomers with a stoichiometry of 1:1. Small-angle X ray scattering analysis revealed that upon binding of HS, OPG undergoes a dramatic conformational change, resulting in a more compact and less flexible structure. Importantly, we present here three lines of evidence that HS, OPG, and RANKL form a stable ternary complex. Using a HS binding-deficient OPG mutant, we further show that in an osteoblast/bone marrow macrophage co-culture system, immobilization of OPG by HS at the osteoblast cell surface substantially lowers the inhibitory threshold of OPG toward RANKL. These discoveries strongly suggest that HS plays an active role in regulating OPG-RANKL interaction and osteoclastogenesis. PMID- 27697836 TI - Preventing tumor escape by targeting a post-proteasomal trimming independent epitope. AB - Adoptive T cell therapy (ATT) can achieve regression of large tumors in mice and humans; however, tumors frequently recur. High target peptide-major histocompatibility complex-I (pMHC) affinity and T cell receptor (TCR)-pMHC affinity are thought to be critical to preventing relapse. Here, we show that targeting two epitopes of the same antigen in the same cancer cells via monospecific T cells, which have similar pMHC and pMHC-TCR affinity, results in eradication of large, established tumors when targeting the apparently subdominant but not the dominant epitope. Only the escape but not the rejection epitope required postproteasomal trimming, which was regulated by IFN-gamma, allowing IFN-gamma-unresponsive cancer variants to evade. The data describe a novel immune escape mechanism and better define suitable target epitopes for ATT. PMID- 27697840 TI - MukB-mediated Catenation of DNA Is ATP and MukEF Independent. AB - Properly condensed chromosomes are necessary for accurate segregation of the sisters after DNA replication. The Escherichia coli condesin is MukB, a structural maintenance of chromosomes (SMC)-like protein, which forms a complex with MukE and the kleisin MukF. MukB is known to be able to mediate knotting of a DNA ring, an intramolecular reaction. In our investigations of how MukB condenses DNA we discovered that it can also mediate catenation of two DNA rings, an intermolecular reaction. This activity of MukB requires DNA binding by the head domains of the protein but does not require either ATP or its partner proteins MukE or MukF. The ability of MukB to mediate DNA catenation underscores its potential for bringing distal regions of a chromosome together. PMID- 27697841 TI - Proprotein Convertase Processing Enhances Peroxidasin Activity to Reinforce Collagen IV. AB - The basement membrane (BM) is a form of extracellular matrix that underlies cell layers in nearly all animal tissues. Type IV collagen, a major constituent of BMs, is critical for tissue development and architecture. The enzyme peroxidasin (Pxdn), an extracellular matrix-associated protein, catalyzes the formation of structurally reinforcing sulfilimine cross-links within the collagen IV network, an event essential to basement membrane integrity. Although the catalytic function of Pxdn is known, the regulation of its activity remains unclear. In this work we show through N-terminal sequencing, pharmacologic studies, and mutational analysis that proprotein convertases (PCs) proteolytically process human Pxdn at Arg-1336, a location relatively close to its C terminus. PC processing enhances the enzymatic activity of Pxdn and facilitates the formation of sulfilimine cross-links in collagen IV. Thus, PC processing of Pxdn is a key regulatory step that contributes to its function and, therefore, supports BM integrity and homeostasis. PMID- 27697842 TI - Mammalian Nonmuscle Myosin II Binds to Anionic Phospholipids with Concomitant Dissociation of the Regulatory Light Chain. AB - Mammalian cells express three Class II nonmuscle myosins (NM): NM2A, NM2B, and NM2C. The three NM2s have well established essential roles in cell motility, adhesion, and cytokinesis and less well defined roles in vesicle transport and other processes that would require association of NM2s with cell membranes. Previous evidence for the mechanism of NM2-membrane association includes direct interaction of NM2s with membrane lipids and indirect interaction by association of NM2s with membrane-bound F-actin or peripheral membrane proteins. Direct binding of NM2s to phosphatidylserine-liposomes, but not to phosphatidylcholine liposomes, has been reported, but the molecular basis of the interaction between NM2s and acidic phospholipids has not been previously investigated. We now show that filamentous, full-length NM2A, NM2B, and NM2C and monomeric, non-filamentous heavy meromyosin bind to liposomes containing one or more acidic phospholipids (phosphatidylserine, phosphatidylinositol 4,5-diphosphate, and phosphatidylinositol 3,4,5-triphosphate) but do not bind to 100% phosphatidylcholine-liposomes. Binding of NM2s to acidic liposomes occurs predominantly through interaction of the liposomes with the regulatory light chain (RLC) binding site in the myosin heavy chain with concomitant dissociation of the RLC. Phosphorylation of myosin-bound RLC by myosin light chain kinase substantially inhibits binding to liposomes of both filamentous NM2 and non filamentous heavy meromyosin; the addition of excess unbound RLC, but not excess unbound essential light chain, competes with liposome binding. Consistent with the in vitro data, we show that endogenous and expressed NM2A associates with the plasma membrane of HeLa cells and fibrosarcoma cells independently of F-actin.

AB - This article examines anxieties concerning organ transplantation in Nalo Hopkinson's prize-winning novel Brown Girl in the Ring (1998). The main focus is how this novel re-imagines subjectivity and selfhood as an embodied metaphor for the reconfiguring of broader sociopolitical relations. In other words, this article analyses the relationship between the transplanted body and the body politic, arguing that a post-transplant identity, where there is little separation between donor and recipient, is the foundation for a politics based on responsibility for others. Such a responsibility poses a challenge to the race and class segregation that is integral to the post-apocalyptic world of Hopkinson's novel. Transplantation is not a utopian vision of an egalitarian society coming together in one body; rather, this biotechnological intervention offers a potentially different mode of thinking what it means to work across race, class and embodied division, while always recalling the violence that might facilitate so-called medical progress.

AB - BACKGROUND: Injury to the spinal cord can result in loss of sympathetic innervation causing a drop in BP and HR, this condition is known as neurogenic shock. There is debate among the literature on how and when neurogenic shock presents and what values of HR and BP should be used to define it. Previous studies do not take into account multiple prehospital and emergency department recordings. OBJECTIVE: To improve understanding of how neurogenic shock presents in humans, allowing better identification and treatment. METHODS: The Trauma Audit and Research Network database for an adult major trauma centre was used to isolate patients with a spinal cord injury. Qualifying patients had all available BPs and HRs collated into a database. Patients with neurogenic shock were isolated, allowing data analysis. RESULTS: Out of 3069 trauma patients, 33 met the inclusion criteria, of which 15 experienced neurogenic shock. 87% of the patients who had neurogenic shock experienced it within 2 hours of injury. Neurogenic shock below the T6 level was less common (p=0.009); however, there were still four cases in the cohort. More patients with complete spinal cord injury had neurogenic shock (p=0.039). CONCLUSIONS: Neurogenic shock is variable and unpredictable. It can present in the prehospital environment and without warning in a patient with previously normal vital signs. The medical team should be aware of it in all patients with spinal cord injury regardless of injury level.

AB - This qualitative study explored a multisensory (including olfactory) intervention for people with dementia. Six themed boxes (e.g. Childhood) containing items chosen from the Boots archive designed to encourage conversation were used in weekly group sessions. Session participants were people with dementia and care staff from a local care home, a trained facilitator and archivists from Boots UK. Semi-structured interviews explored participants' experiences of the sessions. Interviews were analysed using thematic analysis. The three major themes Engagement (subthemes: Inclusiveness; Emotional involvement; Factors that supported engagement), What's in the box (subthemes: Contents stimulate memories; Mystery, variety and age of items; Value of olfactory stimuli), and A conversation starter (subtheme: Opportunity for self-expression) reveal the success of the intervention and the value of olfactory stimuli. Multisensory boxes including olfactory stimulation can be an engaging intervention with scope to refine it for people with dementia and their carers in the wider community. PMID- 27697843 TI - Peroxisome proliferator activating receptor-gamma and the podocyte. AB - Over the past two decades it has become clear that the glomerular podocyte is a key cell in preventing albuminuria, kidney failure and cardiovascular morbidity. Understanding the key pathways that protect the podocyte in times of glomerular stress, which can also be therapeutically manipulated, are highly attractive. In the following review we assess the evidence that the peroxisome proliferator activating receptor (PPAR) agonists are beneficial for podocyte and kidney function with a focus on PPAR-gamma. We explain our current understanding of the mechanisms of action of these agonists and the evidence they are beneficial in diabetic and non-diabetic kidney disease. We also outline why these drugs have not been widely used for kidney disease in the past but they may be in the future. PMID- 27697847 TI - The vestibular system is critical for the changes in muscle and bone induced by hypergravity in mice. AB - Gravity changes concurrently affect muscle and bone as well as induce alterations in vestibular signals. However, the role of vestibular signals in the changes in muscle and bone induced by gravity changes remains unknown. We therefore investigated the effects of vestibular lesions (VL) on the changes in muscle and bone induced by 3 g hypergravity for 4 weeks in C57BL/6J mice. Quantitative computed tomography analysis revealed that hypergravity increased muscle mass surrounding the tibia and trabecular bone mineral content, adjusting for body weight in mice. Hypergravity did not affect cortical bone and fat masses surrounding the tibia. Vestibular lesions blunted the increases in muscle and bone masses induced by hypergravity. Histological analysis showed that hypergravity elevated the cross-sectional area of myofiber in the soleus muscle. The mRNA levels of myogenic genes such as MyoD, Myf6, and myogenin in the soleus muscle were elevated in mice exposed to hypergravity. Vestibular lesions attenuated myofiber size and the mRNA levels of myogenic differentiation markers enhanced by hypergravity in the soleus muscle. Propranolol, a beta-blocker, antagonized the changes in muscle induced by hypergravity. In conclusion, this study is the first to demonstrate that gravity changes affect muscle and bone through vestibular signals and subsequent sympathetic outflow in mice. PMID- 27697848 TI - Comparative Accuracy of 17 Point-of-Care Glucose Meters. AB - BACKGROUND: The accuracy of point-of-care blood glucose (BG) meters is important for the detection of dysglycemia, calculation of insulin doses, and the calibration of continuous glucose monitors. The objective of this study was to compare the accuracy of commercially available glucose meters in a challenging laboratory study using samples with a wide range of reference BG and hemoglobin values. METHODS: Fresh, discarded blood samples from a hospital STAT laboratory were either used without modification, spiked with a glucose solution, or incubated at 37 degrees C to produce 347 samples with an even distribution across reference BG levels from 20 to 440 mg/dl and hemoglobin values from 9 to 16 g/dl. We measured the BG of each sample with 17 different commercially available glucose meters and the reference method (YSI 2300) at the same time. We determined the mean absolute relative difference (MARD) for each glucose meter, overall and stratified by reference BG and by hemoglobin level. RESULTS: The accuracy of different meters widely, exhibiting a range of MARDs from 5.6% to 20.8%. Accuracy was lower in the hypoglycemic range, but was not consistently lower in samples with anemic blood hemoglobin levels. CONCLUSIONS: The accuracy of commercially available glucose meters varies widely. Although the sample mix in this study was much more challenging than those that would be collected under most use conditions, some meters were robust to these challenges and exhibited high accuracy in this setting. These data on relative accuracy and robustness to challenging samples may be useful in informing the choice of a glucose meter. PMID- 27697849 TI - Occipital nerve stimulation improves the quality of life in medically-intractable chronic cluster headache: Results of an observational prospective study. AB - Background Occipital nerve stimulation (ONS) has been proposed to treat chronic medically-intractable cluster headache (iCCH) in small series of cases without evaluation of its functional and emotional impacts. Methods We report the multidimensional outcome of a large observational study of iCCH patients, treated by ONS within a nationwide multidisciplinary network ( https://clinicaltrials.gov NCT01842763), with a one-year follow-up. Prospective evaluation was performed before surgery, then three and 12 months after. Results One year after ONS, the attack frequency per week was decreased >30% in 64% and >50% in 59% of the 44 patients. Mean (Standard Deviation) weekly attack frequency decreased from 21.5 (16.3) to 10.7 (13.8) ( p = 0.0002). About 70% of the patients responded to ONS, 47.8% being excellent responders. Prophylactic treatments could be decreased in 40% of patients. Functional (HIT-6 and MIDAS scales) and emotional (HAD scale) impacts were significantly improved, as well as the health-related quality of life (EQ-5D). The mean (SD) EQ-5D visual analogic scale score increased from 35.2 (23.6) to 51.9 (25.7) ( p = 0.0037). Surgical minor complications were observed in 33% of the patients. Conclusion ONS significantly reduced the attack frequency per week, as well as the functional and emotional headache impacts in iCCH patients, and dramatically improved the health-related quality of life of responders. PMID- 27697850 TI - Environment impacts innate immune ontogeny. AB - Susceptibility to infection and response to vaccination differ between populations and as a function of age. The underlying mechanisms for this age- and population-dependent variation are not known. Specifically, it is unclear if these variations are due to differences in genetically encoded host programs or driven by environmental influences or a combination of both. To address the relationship between gene and environment regarding immune ontogeny, we determined the innate cytokine responses following PRR stimulation of blood mononuclear cells at birth, 1, and 2 yr of age in infants from Caucasian vs . Asian parents and were raised in the same city. At birth, we found that innate cytokine responses were significantly elevated in Asian compared with Caucasian infants. However, these differences waned and responses became more similar over the course of 1-2 yr of living in a similar environment. Our observations that innate response differences present at birth subsequently equalized rather than diverged suggest a key role for environmental effects common to both racial groups in shaping the innate immune responses early in life. Delineating the underlying environmental factors that modulate innate immune responses early in life could provide avenues for targeted beneficial immune modulation. PMID- 27697851 TI - Do "Brain-Training" Programs Work? AB - In 2014, two groups of scientists published open letters on the efficacy of brain training interventions, or "brain games," for improving cognition. The first letter, a consensus statement from an international group of more than 70 scientists, claimed that brain games do not provide a scientifically grounded way to improve cognitive functioning or to stave off cognitive decline. Several months later, an international group of 133 scientists and practitioners countered that the literature is replete with demonstrations of the benefits of brain training for a wide variety of cognitive and everyday activities. How could two teams of scientists examine the same literature and come to conflicting "consensus" views about the effectiveness of brain training?In part, the disagreement might result from different standards used when evaluating the evidence. To date, the field has lacked a comprehensive review of the brain training literature, one that examines both the quantity and the quality of the evidence according to a well-defined set of best practices. This article provides such a review, focusing exclusively on the use of cognitive tasks or games as a means to enhance performance on other tasks. We specify and justify a set of best practices for such brain-training interventions and then use those standards to evaluate all of the published peer-reviewed intervention studies cited on the websites of leading brain-training companies listed on Cognitive Training Data (www.cognitivetrainingdata.org), the site hosting the open letter from brain training proponents. These citations presumably represent the evidence that best supports the claims of effectiveness.Based on this examination, we find extensive evidence that brain-training interventions improve performance on the trained tasks, less evidence that such interventions improve performance on closely related tasks, and little evidence that training enhances performance on distantly related tasks or that training improves everyday cognitive performance. We also find that many of the published intervention studies had major shortcomings in design or analysis that preclude definitive conclusions about the efficacy of training, and that none of the cited studies conformed to all of the best practices we identify as essential to drawing clear conclusions about the benefits of brain training for everyday activities. We conclude with detailed recommendations for scientists, funding agencies, and policymakers that, if adopted, would lead to better evidence regarding the efficacy of brain-training interventions.

AB - Post-translational modifications (PTMs) regulate protein behavior through modulation of protein-protein interactions, enzymatic activity, and protein stability essential in the translation of genotype to phenotype in eukaryotes. Currently, less than 4% of all eukaryotic PTMs are reported to have biological function - a statistic that continues to decrease with an increasing rate of PTM detection. Previously, we developed SAPH-ire (Structural Analysis of PTM Hotspots) - a method for the prioritization of PTM function potential that has been used effectively to reveal novel PTM regulatory elements in discrete protein families (Dewhurst et al., 2015). Here, we apply SAPH-ire to the set of eukaryotic protein families containing experimental PTM and 3D structure data - capturing 1,325 protein families with 50,839 unique PTM sites organized into 31,747 modified alignment positions (MAPs), of which 2010 (~6%) possess known biological function. Here, we show that using an artificial neural network model (SAPH-ire NN) trained to identify MAP hotspots with biological function results in prediction outcomes that far surpass the use of single hotspot features, including nearest neighbor PTM clustering methods. We find the greatest enhancement in prediction for positions with PTM counts of five or less, which represent 98% of all MAPs in the eukaryotic proteome and 90% of all MAPs found to have biological function. Analysis of the top 1092 MAP hotspots revealed 267 of truly unknown function (containing 5443 distinct PTMs). Of these, 165 hotspots could be mapped to human KEGG pathways for normal and/or disease physiology. Many high-ranking hotspots were also found to be disease-associated pathogenic sites of amino acid substitution despite the lack of observable PTM in the human protein family member. Taken together, these experiments demonstrate that the functional relevance of a PTM can be predicted very effectively by neural network models, revealing a large but testable body of potential regulatory elements that impact hundreds of different biological processes important in eukaryotic biology and human health.

AB - Clinical responses to high-dose IL2 therapy are limited due to selective expansion of CD4+CD25+Foxp3+ T-regulatory cells (Treg), especially ICOS+ Tregs, rather than natural killer (NK) cells and effector T cells. These ICOS+ Tregs are highly suppressive and constitutively express high levels of IL2Ralpha (CD25) and CD39. Here, we characterized the effect of a mutant form of IL2 (F42K), which preferentially binds to the lower affinity IL2Rbetagamma with reduced binding to CD25, on Tregs, effector NK cells, and T-cell subsets. Unlike wild-type (WT) IL2, F42K did not efficiently induce the expansion of highly suppressive ICOS+ Tregs in peripheral blood mononuclear cells (PBMC) from healthy controls and melanoma patients. Instead, it promoted the expansion of CD16+CD56+ NK cells and CD56hiCD16- NK cell subsets in both short- and long-term cultures, with enhanced Bcl-2 expression. Stimulation of PBMCs with F42K induced expression of more NK cell activation molecules, such as NKp30, NKp44, DNAM-1, NKG2D, 4-1BB/CD137, and Tim-3, than WT IL2. F42K induced greater upregulation of TRAIL, and NK-mediated cytolytic activity was increased against both autologous and HLA-mismatched melanoma cells compared with WT IL2. Gene expression analysis revealed distinct gene expression profiles stimulated by F42K, WT IL2, and IL15. F42K therapy in vivo also induced a dramatic reduction in the expansion of ICOS+ Tregs, promoted NK cell expansion, and inhibited melanoma tumor growth more efficiently than WT IL2 and more effectively than anti-CTLA-4. Our findings suggest that F42K could be a potential substitute for WT IL2 as a cytokine therapy for cancer. Cancer Immunol Res; 4(11); 983-94. (c)2016 AACR. PMID- 27697859 TI - Transcriptional Maintenance of Pancreatic Acinar Identity, Differentiation, and Homeostasis by PTF1A. AB - Maintenance of cell type identity is crucial for health, yet little is known of the regulation that sustains the long-term stability of differentiated phenotypes. To investigate the roles that key transcriptional regulators play in adult differentiated cells, we examined the effects of depletion of the developmental master regulator PTF1A on the specialized phenotype of the adult pancreatic acinar cell in vivo Transcriptome sequencing and chromatin immunoprecipitation sequencing results showed that PTF1A maintains the expression of genes for all cellular processes dedicated to the production of the secretory digestive enzymes, a highly attuned surveillance of unfolded proteins, and a heightened unfolded protein response (UPR). Control by PTF1A is direct on target genes and indirect through a ten-member transcription factor network. Depletion of PTF1A causes an imbalance that overwhelms the UPR, induces cellular injury, and provokes acinar metaplasia. Compromised cellular identity occurs by derepression of characteristic stomach genes, some of which are also associated with pancreatic ductal cells. The loss of acinar cell homeostasis, differentiation, and identity is directly relevant to the pathologies of pancreatitis and pancreatic adenocarcinoma. PMID- 27697860 TI - Absolute Amounts and Status of the Nrf2-Keap1-Cul3 Complex within Cells. AB - The transcription factor Nrf2 (NF-E2-related-factor 2) is essential for the oxidative and electrophilic stress responses. Keap1 (Kelch-like-ECH-associated protein 1), an adaptor for a cullin-3 (Cul3)-based ubiquitin ligase, regulates Nrf2 activity through proteasomal degradation, and acts as a sensor for oxidative and electrophilic stresses. The Keap1-Cul3 complex is a critical regulator of the cellular Nrf2 level, and yet quantitative information regarding their endogenous intracellular concentrations in homeostatic conditions and during stress responses is unknown. We analyzed the absolute amounts of the Nrf2, Keap1, and Cul3 proteins in five murine cell lines by comparison with serial dilutions of purified recombinant protein standards in combination with quantitative immunoblot analyses. In the basal state, the amount of Nrf2 was maintained at lower levels than those of Keap1 and Cul3 proteins, whereas the electrophilic agent diethylmaleate dramatically increased Nrf2 to a level greater than that of Keap1 and Cul3, resulting in the accumulation of Nrf2 in the nucleus. In contrast, Keap1 and Cul3 did not display any changes in their abundance, subcellular localization, or interaction in response to electrophilic stimuli. Our results demonstrate that the regulation of the Nrf2 protein level during stress responses is mediated by the activity but not the composition of the Nrf2 Keap1-Cul3 complex. PMID- 27697861 TI - SIK2 Restricts Autophagic Flux To Support Triple-Negative Breast Cancer Survival. AB - Triple-negative breast cancer (TNBC) is a highly heterogeneous disease with multiple, distinct molecular subtypes that exhibit unique transcriptional programs and clinical progression trajectories. Despite knowledge of the molecular heterogeneity of the disease, most patients are limited to generic, indiscriminate treatment options: cytotoxic chemotherapy, surgery, and radiation. To identify new intervention targets in TNBC, we used large-scale, loss-of function screening to identify molecular vulnerabilities among different oncogenomic backgrounds. This strategy returned salt inducible kinase 2 (SIK2) as essential for TNBC survival. Genetic or pharmacological inhibition of SIK2 leads to increased autophagic flux in both normal-immortalized and tumor-derived cell lines. However, this activity causes cell death selectively in breast cancer cells and is biased toward the claudin-low subtype. Depletion of ATG5, which is essential for autophagic vesicle formation, rescued the loss of viability following SIK2 inhibition. Importantly, we find that SIK2 is essential for TNBC tumor growth in vivo Taken together, these findings indicate that claudin-low tumor cells rely on SIK2 to restrain maladaptive autophagic activation. Inhibition of SIK2 therefore presents itself as an intervention opportunity to reactivate this tumor suppressor mechanism. PMID- 27697862 TI - Human PDCD2L Is an Export Substrate of CRM1 That Associates with 40S Ribosomal Subunit Precursors. AB - Protein arginine methyltransferase 3 (PRMT3) forms a stable complex with 40S ribosomal protein S2 (RPS2) and contributes to ribosome biogenesis. However, the molecular mechanism by which PRMT3 influences ribosome biogenesis and/or function still remains unclear. Using quantitative proteomics, we identified human programmed cell death 2-like (PDCD2L) as a novel PRMT3-associated protein. Our data suggest that RPS2 promotes the formation of a conserved extraribosomal complex with PRMT3 and PDCD2L. We also show that PDCD2L associates with 40S subunit precursors that contain a 3'-extended form of the 18S rRNA (18S-E pre rRNA) and several pre-40S maturation factors. PDCD2L shuttles between the nucleus and the cytoplasm in a CRM1-dependent manner using a leucine-rich nuclear export signal that is sufficient to direct the export of a reporter protein. Although PDCD2L is not required for the biogenesis and export of 40S ribosomal subunits, we found that PDCD2L-null cells accumulate free 60S ribosomal subunits, which is indicative of a deficiency in 40S subunit availability. Our data also indicate that PDCD2L and its paralog, PDCD2, function redundantly in 40S ribosomal subunit production. Our findings uncover the existence of an extraribosomal complex consisting of PDCD2L, RPS2, and PRMT3 and support a role for PDCD2L in the late maturation of 40S ribosomal subunits. PMID- 27697863 TI - Endoplasmic Reticulum Stress Enhances Mitochondrial Metabolic Activity in Mammalian Adrenals and Gonads. AB - The acute response to stress consists of a series of physiological programs to promote survival by generating glucocorticoids and activating stress response genes that increase the synthesis of many chaperone proteins specific to individual organelles. In the endoplasmic reticulum (ER), short-term stress triggers activation of the unfolded protein response (UPR) module that either leads to neutralization of the initial stress or adaptation to it; chronic stress favors cell death. UPR induces expression of the transcription factor, C/EBP homology protein (CHOP), and its deletion protects against the lethal consequences of prolonged UPR. Here, we show that stress-induced CHOP expression coincides with increased metabolic activity. During stress, the ER and mitochondria come close to each other, resulting in the formation of a complex consisting of the mitochondrial translocase, translocase of outer mitochondrial membrane 22 (Tom22), steroidogenic acute regulatory protein (StAR), and 3beta hydroxysteroid dehydrogenase type 2 (3betaHSD2) via its intermembrane space (IMS) exposed charged unstructured loop region. Stress increased the circulation of phosphates, which elevated pregnenolone synthesis by 2-fold by increasing the stability of 3betaHSD2 and its association with the mitochondrion-associated ER membrane (MAM) and mitochondrial proteins. In summary, cytoplasmic CHOP plays a central role in coordinating the interaction of MAM proteins with the outer mitochondrial membrane translocase, Tom22, to activate metabolic activity in the IMS by enhanced phosphate circulation.

AB - Chromosome transmission fidelity during mitosis is of critical importance for the fitness of an organism, as mistakes will lead to aneuploidy, which has a causative role in numerous severe diseases. Proper segregation of chromosomes depends on interdependent processes at the microtubule-kinetochore interface and the spindle assembly checkpoint. Here we report the discovery of a new element essential for chromosome transmission fidelity that implicates inositol pyrophosphates (IPPs) as playing a key role in this process. The protein is Asp1, the Schizosaccharomyces pombe member of the highly conserved Vip1 family. Vip1 enzymes are bifunctional: they consist of an IPP-generating kinase domain and a pyrophosphatase domain that uses such IPPs as substrates. We show that Asp1 kinase function is required for bipolar spindle formation. The absence of Asp1 generated IPPs resulted in errors in sister chromatid biorientation, a prolonged checkpoint-controlled delay of anaphase onset, and chromosome missegregation. Remarkably, expression of Asp1 variants that generated higher-than-wild-type levels of IPPs led to a faster-than-wild-type entry into anaphase A without an increase in chromosome missegregation. In fact, the chromosome transmission fidelity of a nonessential chromosome was enhanced with increased cellular IPPs. Thus, we identified an element that optimized the wild-type chromosome transmission process. PMID- 27697866 TI - SHP-1 Acts as a Key Regulator of Alloresponses by Modulating LFA-1-Mediated Adhesion in Primary Murine T Cells. AB - The clinical potential of transplantation is often reduced by T cell-mediated alloresponses that cause graft rejection or graft-versus-host disease. Integrin mediated adhesion between alloreactive T cells and antigen-presenting cells is essential for allorejection. The identity of the signaling events needed for the activation of integrins such as LFA-1 is poorly understood. Here, we identified a novel role of the protein tyrosine phosphatase SHP-1 in the regulation of murine LFA-1-mediated adhesion in an allograft setting. Upon alloactivation, SHP-1 activity is reduced, resulting in an increase in LFA-1 adhesion compared to that for syngeneically activated T cells. The importance of these differential activation properties was further indicated by small interfering RNA (siRNA) knockdown of SHP-1 in syngeneically and allogeneically stimulated T cells. Mechanistically, SHP-1 modulated the binding of SLP-76 to ADAP by dephosphorylation of the YDGI tyrosine motif of ADAP, a known docking site for the Src family kinase Fyn. This novel key role of SHP-1 in the regulation of LFA 1-mediated adhesion may provide a new insight into T cell-mediated alloresponses and may pave the way to the development of new immunosuppressive pharmaceutical agents. PMID- 27697864 TI - AMPK and Endothelial Nitric Oxide Synthase Signaling Regulates K-Ras Plasma Membrane Interactions via Cyclic GMP-Dependent Protein Kinase 2. AB - K-Ras must localize to the plasma membrane and be arrayed in nanoclusters for biological activity. We show here that K-Ras is a substrate for cyclic GMP dependent protein kinases (PKGs). In intact cells, activated PKG2 selectively colocalizes with K-Ras on the plasma membrane and phosphorylates K-Ras at Ser181 in the C-terminal polybasic domain. K-Ras phosphorylation by PKG2 is triggered by activation of AMP-activated protein kinase (AMPK) and requires endothelial nitric oxide synthase and soluble guanylyl cyclase. Phosphorylated K-Ras reorganizes into distinct nanoclusters that retune the signal output. Phosphorylation acutely enhances K-Ras plasma membrane affinity, but phosphorylated K-Ras is progressively lost from the plasma membrane via endocytic recycling. Concordantly, chronic pharmacological activation of AMPK -> PKG2 signaling with mitochondrial inhibitors, nitric oxide, or sildenafil inhibits proliferation of K Ras-positive non-small cell lung cancer cells. The study shows that K-Ras is a target of a metabolic stress-signaling pathway that can be leveraged to inhibit oncogenic K-Ras function. PMID- 27697867 TI - Enhanced Stabilization of MCL1 by the Human T-Cell Leukemia Virus Type 1 bZIP Factor Is Modulated by Blocking the Recruitment of Cullin 1 to the SCF Complex. AB - Human T-cell leukemia virus type 1 (HTLV-1) is an oncogenic retrovirus that is the etiological agent of adult T-cell leukemia (ATL). The HTLV-1 basic leucine zipper factor (HBZ), which is encoded by the minus strand of the provirus, is constitutively expressed in all ATL patient cells and likely contributes to the development and maintenance of ATL. Furthermore, the overexpression of the myeloid cell leukemia 1 (MCL1) protein is frequently observed in hematological cancers as well as several other types of cancers. Here, we found that the expression of HBZ in cells stabilized MCL1 protein expression and suppressed the MCL1-mediated release of cytochrome c from the mitochondria. This effect was mediated by inhibition of the ubiquitin-dependent degradation of MCL1. In a serial binding assay, HBZ interacted with cullin 1 (CUL1) through a head-to-tail interaction. The association between CUL1 and Skp1, which serves as the molecular scaffold for the components of SCF ubiquitin ligase complexes, was markedly repressed in the presence of HBZ. Mechanistic analysis indicated that HBZ abrogated the CUL1 association with Skp1, which in turn promoted the cellular expression of MCL1. This novel function of HBZ likely plays a role in the viral pathogenesis of HTLV-1 and provides important insights into our understanding of the development of ATL.

AB - INTRODUCTION: Crowdsourcing has been used to spur innovation and increase community engagement in public health programmes. Crowdsourcing is the process of giving individual tasks to a large group, often involving open contests and enabled through multisectoral partnerships. Here we describe one crowdsourced video intervention in which a video promoting condom use is produced through an open contest. The aim of this study is to determine whether a crowdsourced intervention is as effective as a social marketing intervention in promoting condom use among high-risk men who have sex with men (MSM) and transgender male to-female (TG) in China. METHOD: We evaluate videos developed by crowdsourcing and social marketing. The crowdsourcing contest involved an open call for videos. Entries were judged on capacity to promote condom use, to be shareable or 'go viral' and to give value to the individual. 1170 participants will be recruited for the randomised controlled trial. Participants need to be MSM age 16 and over who have had condomless anal sex in the last 3 months. Recruitment will be through an online banner ad on a popular MSM web page and other social media platforms. After completing an initial survey, participants will be randomly assigned to view either the social marketing video or the crowdsourcing video. Follow-up surveys will be completed at 3 weeks and 3 months after initial intervention to evaluate condomless sex and related secondary outcomes. Secondary outcomes include condom social norms, condom negotiation, condom self-efficacy, HIV/syphilis testing, frequency of sex acts and incremental cost. ETHICS AND DISSEMINATION: Approval was obtained from the ethical review boards of the Guangdong Provincial Center for Skin Diseases and STI Control, UNC and UCSF. The results of this trial will be made available through publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT02516930.

These symptoms can appear at any time following radiotherapy. This study focuses on the early identification and protocol-based management of effects known to cause long-term, or even permanent, changes to the well-being of prostate cancer survivors. The rationale of this study is to improve the care offered to men and their families following pelvic radiotherapy for prostate cancer. METHOD AND ANALYSIS: Implementation research methodology will be used to adopt a multicomponent intervention at three UK centres. The intervention package comprises a standardised clinical assessment of relevant symptoms in oncology outpatient clinics and rapid referral to an enhanced gastroenterological service for patients identified with bowel problems. Gastroenterology staff will be trained to use an expert-practice algorithm of targeted gastroenterology investigations and treatments. The evaluation of the intervention and its embedding within local practices will be conducted using a mixed-methods design. The effect of the new service will be measured in terms of the following outcomes: acceptability to staff and patients; quality of life; symptom control and cost-effectiveness. Data collection will take place at baseline, 6 months (+/-2 months), and 12 months (+/-2 months) after entry into the study. ETHICS AND DISSEMINATION: The study has ethical approval from the North West-Liverpool East Research Ethics Committee and the appropriate NHS governance clearance. All participants provide written informed consent. The study team aim to publish the results of the study in peer-reviewed journals as well as at national and international conferences. TRIAL REGISTRATION NUMBER: UKCRN16974. PMID- 27697870 TI - Prevalence, discomfort and self-relief behaviours of painful diabetic neuropathy in Taiwan: a cross-sectional study. AB - OBJECTIVES: To explore the prevalence, discomfort, and self-relief behaviours of painful diabetic neuropathy (PDN) among rural community residents with type 2 diabetes. DESIGN: A community-based, cross-sectional study. SETTING: This study was part of a longitudinal cohort study of a nurse-led health promotion programme for preventing foot ulceration in Chiayi County, Taiwan. PARTICIPANTS: Six hundred and twenty-eight community adults with type 2 diabetes participated in this study. OUTCOME MEASURES: Parameters assessed included peripheral neuropathy, peripheral vasculopathy, glycaemic control and metabolic biomarkers. Statistical analyses included descriptive statistics and a multivariate logistic regression model. RESULTS: About 30.6% of participants (192/628) had PDN. Factors associated with PDN included an abnormal ankle brachial index (ABI; OR=3.4; 95% CI 1.9 to 6.2; p<0.001), Michigan neuropathy screening index (OR=1.69; 95% CI 1.0 to 2.6; p=0.021), triglyceride level (OR=1.61; 95% CI 1.0 to 2.4; p=0.036) and being female (OR=1.68; 95% CI 1.1 to 2.4; p=0.022). PDN was characterised by uncomfortable feelings of prickling, stinging or burning pain and inexplicable dullness around the base or dorsal areas of the feet, but received little attention or treatment from primary healthcare providers. CONCLUSIONS: A high prevalence of PDN was found in rural community residents with type 2 diabetes and the healthcare workers provided little attention to, or treatment of, discomfort. It is important to identify high-risk groups with PDN early in order to prevent foot ulceration and reduce the incidence of amputation of the extremities. It is also urgent to develop appropriate treatment and self-relief behaviours to halt or reverse the progression of PDN for this population living in rural areas. PMID- 27697871 TI - Prevalence and predictors of latent tuberculosis infection among Italian State Policemen engaged in assistance to migrants: a national cross-sectional study. AB - OBJECTIVES: Better knowledge about tuberculosis (TB) and latent TB infection (LTBI) epidemiology is a crucial step for the development of effective strategies towards the control and elimination of this deadliest and persistent health threat. No study has investigated LTBI epidemiology in policemen who act as an interface with cross-border migrants. METHODS: A survey to measure the LTBI prevalence and assess the demographic, professional and clinical features potentially associated with tuberculin skin test (TST) positivity was performed in Italian State Police (ISP) employees engaged, even occasionally, in relief activities, hospitality, photographical identification, escorting and accompanying of migrants, regardless of contact with active TB cases. Variables potentially associated with TST positivity were evaluated with univariate and multivariate analysis. RESULTS: From September to December 2014, 4225 ISP workers underwent TST screening and completed the questionnaire for data collection, according to study procedures. The TST was positive in 9.9% of individuals: no active TB cases were registered among the entire study population. Age, previous BCG vaccination and work category resulted independently associated with TST positivity. CONCLUSIONS: This is the first study providing updated data about LTBI epidemiology among ISP employees engaged in assistance to migrants and furnish preliminary evidence of possible associations between TST positivity and different conditions that need to be deeply investigated with prospective studies. PMID- 27697872 TI - Identifying different typologies of experiences and coping strategies in men with rheumatoid arthritis: a Q-methodology study. AB - OBJECTIVE: To identify typologies of experiences and coping strategies of men with rheumatoid arthritis (RA). DESIGN: Q-methodology (a qualitative and quantitative approach to grouping people according to their subjective opinion). Men with RA sorted 64 statements relating to their experience of living with RA according to level of agreement across a normal distribution grid. Data were examined using Q-factor analysis. SETTING: Rheumatology outpatient departments in the UK. PARTICIPANTS: 30 of 65 invited men with RA participated in this study (46%). RESULTS: All participants ranked highly the need to be well informed about their medication and the importance of keeping a positive attitude. 2 factors describing the experiences and coping strategies of male patients living with RA were identified: factor A: 'acknowledge, accept and adapt' (n=14) take a proactive approach to managing the impact of RA and find different ways of doing things; while factor B: 'trying to match up to a macho ideal' (n=8) are determined to continue with their pre-RA lives, and therefore push themselves to carry on even if this causes them pain. They are frustrated and angry due to the impact of RA but they internalise this rather than directing it at others. CONCLUSIONS: While some men adapt to their RA by renegotiating their masculine identity, others struggle to relinquish their traditional masculine roles. Further research is needed to identify whether the finding that there are 2 distinct groups of men with RA can be generalised, and if so whether the differences can be explained by clinical, social or psychological factors, which may inform different therapeutic approaches. PMID- 27697873 TI - Assessment for the possibility of a first night effect for wrist actigraphy in adolescents. AB - OBJECTIVES: Evidence of a 'first night effect' has been documented for polysomnography. The possibility of this has not been previously assessed in wrist actigraphy, yet may have important implications for the study design of future sleep research. We sought to examine potential evidence of a 'first night effect' for wrist actigraphy in adolescents across weekdays and weekend nights for multiple sleep outcomes. DESIGN: 3-year prospective cohort study (Midlands Adolescent Schools Sleep Education Study). SETTING: 8 secondary schools in the Midlands region of the UK. PARTICIPANTS: Adolescents (aged 11-13 years at baseline) were recruited to the study and were requested to wear a wrist actigraph for 7 consecutive days/nights at baseline and then annually for 2 years during the second term of the academic year. PRIMARY OUTCOME MEASURES: We compared multiple sleep outcomes (total sleep time, wake after sleep onset, sleep efficiency, sleep onset latency, number of awakenings, length of awakenings, sleep onset time) when the device was worn on a weekday and weekend and compared these to other nights to identify possible evidence of a 'first night effect' for wrist actigraphy. RESULTS: No significant differences were found between any sleep outcomes when the first night of wrist actigraphy was on a weekday compared with other weekdays. When the first night was measured on a weekend (Friday), average total sleep time was significantly greater (486+/-5 min) compared with the second night (Saturday; 469+/-6 min), p=0.01. CONCLUSIONS: We found no evidence to support a 'first night effect' for wrist actigraphy in our adolescent sample. The first night of actigraphy data should not be disregarded in future studies that deploy this technique to measure sleep over prolonged time periods. PMID- 27697874 TI - Effect of day-case unilateral cochlear implantation in adults on general and disease-specific quality of life, postoperative complications and hearing results, tinnitus, vertigo and cost-effectiveness: protocol for a randomised controlled trial. AB - INTRODUCTION: Cochlear implantation is an increasingly common procedure in the treatment of severe to profound sensorineural hearing loss (SNHL) in children and adults. It is often performed as a day-case procedure. The major drive towards day-case surgery has been from a logistical, economical and societal perspective, but we also speculate that the patient's quality of life (QoL) is at least equal to inpatient surgery if not increased as a result of rapid discharge and rehabilitation. Even though cochlear implantation seems well suited to a day-case approach and this even seems to be common practice in some countries, evidence is scarce and of low quality to guide us towards the preferred treatment option. METHODS AND ANALYSIS: A single-centre, non-blinded, randomised, controlled trial was designed to (primarily) investigate the effect on general QoL of day-case cochlear implantation compared to inpatient cochlear implantation and (secondarily) the effect of both methods on (subjective) hearing improvement, disease-specific QoL, tinnitus, vertigo and cost-effectiveness. 30 adult patients with severe to profound bilateral postlingual SNHL who are eligible for unilateral cochlear implantation will be randomly assigned to either the day-case or inpatient treatment group. The outcome measures will be assessed using auditory evaluations, questionnaires (preoperatively, at 1-week, 3-week, 3-month and 1-year follow-up) and costs diaries (weekly during the first month postoperatively, after which once in a month until 1-year follow-up). Preoperative and postoperative outcomes will be compared. The difference in costs and benefit will be represented using the incremental cost utility/effectiveness ratio. The analyses will be carried out on an intention-to-treat basis. ETHICS AND DISSEMINATION: This research protocol was approved by the Institutional Review Board of the UMC Utrecht (NL45590.041.13; V.5, November 2015). The trial results will be disseminated through peer-reviewed medical journals and presented at scientific conferences. TRIAL REGISTRATION NUMBER: NTR4464; Pre-results. PMID- 27697875 TI - Current practices in patient-reported outcome (PRO) data collection in clinical trials: a cross-sectional survey of UK trial staff and management. AB - OBJECTIVES: Patient-reported outcome measures (PROMs) collected in clinical trials should be administered in a standardised way across sites and routinely screened for avoidable missing data in order to maximise data quality/minimise risk of bias. Recent qualitative findings, however, have raised concerns about the consistency of PROM administration in UK trials. The purpose of this study was to determine the generalisability of these findings across the wider community of trial personnel. DESIGN: Online cross-sectional survey. SETTING: Participants were recruited from 55 UK Clinical Research Collaboration Registered Clinical Trials Units and 19 Comprehensive Local Research Networks. PARTICIPANTS: Research nurses, data managers/coordinators, trial managers and chief/principal investigators involved in clinical trials collecting PROMs. ANALYSIS: We undertook descriptive analyses of the quantitative data and directed thematic analysis of free-text comments. Factors associated with the management of missing PRO data were explored using logistic regression. RESULTS: Survey data from 767 respondents supported the generalisability of qualitative study findings, suggesting inconsistencies in PROM administration with regard to: the level of assistance given to trial participants; the timing of PROM completion in relation to the clinical consultation; and the management of missing data. Having >=10 years experience in a research role was significantly associated with the appropriate management of missing PROM data (OR 2.26 (95% CI 1.06 to 4.82), p=0.035). There was a consensus that more PROM guidance was needed in future trials and agreement between professional groups about the necessary components. CONCLUSIONS: There are inconsistencies in the way PROMs are administered by trial staff. Such inconsistencies may reduce the quality of data and have the potential to introduce bias. There is a need for improved guidance in future trials that support trial personnel in conducting optimal PROM data collection to inform patient care. PMID- 27697876 TI - Community-based Rehabilitation Training after stroke: protocol of a pilot randomised controlled trial (ReTrain). AB - INTRODUCTION: The Rehabilitation Training (ReTrain) intervention aims to improve functional mobility, adherence to poststroke exercise guidelines and quality of life for people after stroke. A definitive randomised controlled trial (RCT) is required to assess the clinical and cost-effectiveness of ReTrain, which is based on Action for Rehabilitation from Neurological Injury (ARNI). The purpose of this pilot study is to assess the feasibility of such a definitive trial and inform its design. METHODS AND ANALYSIS: A 2-group, assessor-blinded, randomised controlled external pilot trial with parallel mixed-methods process evaluation and economic evaluation. 48 participants discharged from clinical rehabilitation despite residual physical disability will be individually randomised 1:1 to ReTrain (25 sessions) or control (exercise advice booklet). Outcome assessment at baseline, 6 and 9 months include Rivermead Mobility Index; Timed Up and Go Test; modified Patient-Specific Functional Scale; 7-day accelerometry; Stroke Self efficacy Questionnaire, exercise diary, Fatigue Assessment Scale, exercise beliefs and self-efficacy questionnaires, SF-12, EQ-5D-5L, Stroke Quality of Life, Carer Burden Index and Service Receipt Inventory. Feasibility, acceptability and process outcomes include recruitment and retention rates; with measurement burden and trial experiences being explored in qualitative interviews (20 participants, 3 intervention providers). Analyses include descriptive statistics, with 95% CI where appropriate; qualitative themes; intervention fidelity from videos and session checklists; rehearsal of health economic analysis. ETHICS AND DISSEMINATION: National Health Service (NHS) National Research Ethics Service approval granted in April 2015; recruitment started in June. Preliminary studies suggested low risk of serious adverse events; however (minor) falls, transitory muscle soreness and high levels of postexercise fatigue are expected. Outputs include pilot data to inform whether to proceed to a definitive RCT and support a funding application; finalised Trainer and Intervention Delivery manuals for multicentre replication of ReTrain; presentations at conferences, public involvement events; internationally recognised peer-reviewed journal publications, open access sources and media releases.

PMID- 27697877 TI - Arts-based HIV and STI prevention intervention with Northern and Indigenous youth in the Northwest Territories: study protocol for a non-randomised cohort pilot study. AB - INTRODUCTION: Indigenous youth are disproportionately represented in new HIV infection rates in Canada. Current and historical contexts of colonisation and racism, disconnection from culture and land, as well as intergenerational trauma resulting from the legacy of residential schools are social drivers that elevate exposure to HIV among Indigenous peoples. Peer-education and arts-based interventions are increasingly used for HIV prevention with youth. Yet limited studies have evaluated longitudinal effects of arts-based approaches to HIV prevention with youth. The authors present a rationale and study protocol for an arts-based HIV prevention intervention with Northern and Indigenous youth in the Northwest Territories (NWT), Canada. METHODS AND ANALYSIS: This is a multicentre non-randomised cohort pilot study using a pretest/post-test design with a 12 month follow-up. The target population is Northern and Indigenous youth in 18 communities in the NWT. The aim is to recruit 150 youth using venue-based sampling at secondary schools. Participants will be involved in an arts-based intervention, Fostering Open eXpression among Youth (FOXY). Participants will complete a pretest, post-test survey directly following the intervention, and a 12-month follow-up. The primary outcome is new or enhanced HIV knowledge, and secondary outcomes to include: new or enhanced sexually transmitted infections knowledge, and increased self-esteem, resilience, empowerment, safer sex self efficacy and cultural connectedness. Mixed effects regression analyses will be conducted to evaluate pretest and post-test differences in outcome measurement scores. ETHICS AND DISSEMINATION: This study has received approval from the HIV Research Ethics Board at the University of Toronto (REB: 31602). In addition, the project is currently registered in the NWT with the Aurora Research Institute (Licence: 15741). Trial results will be published according to the Transparent Reporting of Evaluations with Nonrandomised Designs statement. TRIAL REGISTRATION NUMBER: NCT02743026; Pre-results. PMID- 27697878 TI - Study protocol of the YP Face IT feasibility study: comparing an online psychosocial intervention versus treatment as usual for adolescents distressed by appearance-altering conditions/injuries. AB - INTRODUCTION: A significant number of adolescents suffer extensive and enduring difficulties such as social anxiety, body image dissatisfaction, low self-esteem and bullying as a result of conditions or injuries that affect their appearance (eg, craniofacial and skin conditions, treatment side effects and scarring). Evidence-based psychosocial interventions to meet their specific needs are currently lacking. YP Face IT, developed by the UK's Centre for Appearance Research in collaboration with clinical experts and young people, is an innovative online psychosocial intervention designed to offer this group immediate support, advice and coping strategies. It has been endorsed by young people, their parents/carers, GPs, clinical psychologists and health professionals working with those affected by appearance-related conditions. METHODS AND ANALYSIS: Young people aged 12-17 with an appearance-altering condition/injury that self-identify as experiencing appearance-related distress, teasing or bullying will be invited to participate via GP practices and UK charities. Consenting participants will be randomised to the intervention (YP Face IT) or the treatment as usual (TAU) control group. Outcome measures will be completed by young people and their parents/carers at baseline, 13, 26 and 52 weeks. Primary outcome measures will be the Body Esteem Scale and the Social Anxiety Scale for Adolescents. Participants will complete other health-related outcome measures and resource use questionnaires for health economic analysis. We will assess recruitment rates, acceptability of the YP Face IT programme, adherence and retention to treatment, questionnaire completion rates, variation of TAU in Primary Care and the feasibility of GP practice staff supervising young people's use of YP Face IT. ETHICS AND DISSEMINATION: This feasibility trial protocol (V.1, 3 March 2014), received a favourable ethical opinion from the NRES Committee South West-Frenchay (reference number 14/SW/0058). Findings will be disseminated through academic peer-reviewed publications, conferences and to participating GP practices and charities supporting those with conditions affecting appearance. TRIAL REGISTRATION NUMBER: ISRCTN40650639; Pre-results. PMID- 27697879 TI - Association between occupational physical activity and myocardial infarction: a prospective cohort study. AB - OBJECTIVE: Recommendations regarding physical activity typically include both leisure time and occupational physical activity. However, the results from previous studies on occupational physical activity and the association with myocardial infarction have been inconsistent. The aim of this study was to investigate if occupational physical activity is associated with the risk of myocardial infarction. DESIGN: Prospective cohort study. PARTICIPANTS: Data from the Swedish Work, Lipids and Fibrinogen (WOLF) study was used, comprising 9961 employees (6849 men, 3112 women, mean age 42.7 years) having no history of myocardial infarction. The participants were categorised into 3 groups according to their level of occupational physical activity. OUTCOME: Data regarding incident myocardial infarction were obtained from the Swedish National Patient Register and the Cause of Death Register. Cox proportional hazard regression was used for estimation of HRs for different levels of occupational physical activity in relation to the risk of myocardial infarction. RESULTS: During a mean follow up of 13.1 years, 249 cases of incident myocardial infarction were identified. In analyses adjusted for age, sex and socioeconomic status, participants standing and walking more than 50% of their working day had an HR of 1.13 (95% CI 0.83 to 1.54), compared with participants seated more than 50% of their working day. The corresponding HR for participants whose work included lifting or carrying was 0.86 (95% CI 0.59 to 1.24). Further adjustment did not alter the results. Stratified analyses resulted in a significantly decreased risk for young people whose work included lifting or carrying, HR 0.37 (95% CI 0.17 to 0.84), compared with younger persons who sat most of their working day. CONCLUSIONS: No significant association between occupational physical activity and the risk of myocardial infarction was observed in the total group of employees in this study. Based on the results from this study, occupational physical activity in general does not seem to be enough for reducing the risk of myocardial infarction. PMID- 27697880 TI - Study protocol for Chronic Obstructive Pulmonary Disease-Sitting and ExacerbAtions Trial (COPD-SEAT): a randomised controlled feasibility trial of a home-based self-monitoring sedentary behaviour intervention. AB - INTRODUCTION: An acute exacerbation of chronic obstructive pulmonary disease (COPD) marks a critical life event, which can lower patient quality of life and ability to perform daily activities. Patients with COPD tend to lead inactive and highly sedentary lifestyles, which may contribute to reductions in functional capacity. Targeting sedentary behaviour (SB) may be more attainable than exercise (at a moderate-to-vigorous intensity) for behaviour change in patients following an exacerbation. This study aims to evaluate the feasibility and acceptability of a 2-week at-home intervention providing education and self-monitoring to reduce prolonged periods of SB in patients with COPD discharged following an acute exacerbation. METHODS AND ANALYSIS: Patients will be randomised into 1 of 3 conditions: usual care (control), education or education+feedback. The education group will receive information and suggestions about reducing long periods of sitting. The education+feedback group will receive real-time feedback on their sitting time, stand-ups and step count at home through an inclinometer linked to a smart device app. The inclinometer will also provide vibration prompts to encourage movement when the wearer has been sedentary for too long. Data will be collected during hospital admission and 2 weeks after discharge. Qualitative interviews will be conducted with patients in the intervention groups to explore patient experiences. Interviews with healthcare staff will also be conducted. All data will be collected January to August 2016. The primary outcomes are feasibility and acceptability, which will be assessed by qualitative interviews, uptake and drop-out rates, reasons for refusing the intervention, compliance, app usage and response to vibration prompts. ETHICS AND DISSEMINATION: The research ethics committee East Midlands Leicester-Central has provided ethical approval for the conduct of this study. The results of the study will be disseminated through appropriate conference proceedings and peer-reviewed journals. TRIAL REGISTRATION NUMBER: ISRCTN13790881; Pre-results. PMID- 27697881 TI - Systematic review protocol assessing the processes for linking clinical trial registries and their published results. AB - INTRODUCTION: Clinical trial registries are an important source of information for tracking clinical trials from their inception through to their reporting, and have been used to measure publication bias and outcome reporting bias. Our aim is to survey and quantify the processes that have been used to identify links between clinical trial registries and published trial reports in studies that rely on these links to evaluate the completeness and accuracy of trial reporting. METHODS AND ANALYSIS: We will identify studies that describe a process for identifying the links between a trial registry included in the WHO International Clinical Trial Registry Platform and published trial results, and use those links to evaluate the completeness and accuracy of trial reporting. Information extracted from the studies will include the purpose and application domain of the study, registries used or searched, processes by which the links were identified, the study period and proportions for which links were found. We will summarise what is known about the number and availability of links between clinical trial registries and published results, and examine how automatic linking, inference and inquiry processes have been used to identify links since the introduction of trial registries. ETHICS AND DISSEMINATION: The systematic review is focused on the analysis of secondary data and does not require ethics approval. The results of the systematic review will be used to inform standard processes used to identify links to and from clinical trial registries in studies that evaluate the completeness and accuracy of clinical trial reports, as well as systematic reviews. Our findings will be disseminated by publishing the systematic review in a peer-reviewed journal, and by engaging with stakeholders from clinical trial registries and bibliographic databases. PMID- 27697883 TI - The Baby Moves prospective cohort study protocol: using a smartphone application with the General Movements Assessment to predict neurodevelopmental outcomes at age 2 years for extremely preterm or extremely low birthweight infants. AB - INTRODUCTION: Infants born extremely preterm (EP; <28 weeks' gestation) and/or with extremely low birth weight (ELBW; <1000 g birth weight) are at increased risk for adverse neurodevelopmental outcomes. However, it is challenging to predict those EP/ELBW infants destined to have long-term neurodevelopmental impairments in order to target early intervention to those in most need. The General Movements Assessment (GMA) in early infancy has high predictive validity for neurodevelopmental outcomes in preterm infants. However, access to a GMA may be limited by geographical constraints and a lack of GMA-trained health professionals. Baby Moves is a smartphone application (app) developed for caregivers to video and upload their infant's general movements to be scored remotely by a certified GMA assessor. The aim of this study is to determine the predictive ability of using the GMA via the Baby Moves app for neurodevelopmental impairment in infants born EP/ELBW. METHODS AND ANALYSIS: This prospective cohort study will recruit infants born EP/ELBW across the state of Victoria, Australia in 2016 and 2017. A control group of normal birth weight (>2500 g birth weight), term-born (>=37 weeks' gestation) infants will also be recruited as a local reference group. Parents will video their infant's general movements at two time points between 3 and 4 months' corrected age using the Baby Moves app. Videos will be scored by certified GMA assessors and classified as normal or abnormal. Parental satisfaction using the Baby Moves app will be assessed via survey. Neurodevelopmental outcome at 2 years' corrected age includes developmental delay according to the Bayley Scales of Infant and Toddler Development-III and cerebral palsy diagnosis. ETHICS AND DISSEMINATION: This study was approved by the Human Research and Ethics Committees at the Royal Children's Hospital, The Royal Women's Hospital, Monash Health and Mercy Health in Melbourne, Australia. Study findings will be disseminated via peer-reviewed publications and conference presentations. PMID- 27697885 TI - The History of GalaFLEX P4HB Scaffold. AB - The GalaFLEX Scaffold (Galatea Surgical, Inc., Lexington, MA) for plastic and reconstructive surgery belongs to a new generation of products for soft tissue reinforcement made from poly-4-hydroxybutyrate (P4HB). Other members of this new family of products include MonoMax Suture (Aesculap AG, Tuttlingen, Germany) for soft tissue approximation, BioFiber Scaffold (Tornier, Inc., Edina, MN) for tendon repair, and Phasix Mesh (C.R. Bard, Inc., Murray Hill, NJ) for hernia repair. Each of these fully resorbable products provides prolonged strength retention, typically 50% to 70% strength retention at 12 weeks, and facilitates remodeling in vivo to provide a strong, lasting repair. P4HB belongs to a naturally occurring class of biopolymers and fibers made from it are uniquely strong, flexible, and biocompatible. GalaFLEX Scaffold is comprised of high strength, resorbable P4HB monofilament fibers. It is a knitted macroporous scaffold intended to elevate, reinforce, and repair soft tissue. The scaffold acts as a lattice for new tissue growth, which is rapidly vascularized and becomes fully integrated with adjacent tissue as the fibers resorb. In this review, we describe the development of P4HB, its production, properties, safety, and biocompatibility of devices made from P4HB. Early clinical results and current clinical applications of products made from P4HB are also discussed. The results of post-market clinical studies evaluating the GalaFLEX Scaffold in rhytidectomy and cosmetic breast surgery demonstrate that the scaffold can reinforce lifted soft tissue, resulting in persistent surgical results in the face and neck at one year, and provide lower pole stability after breast lift at one year. PMID- 27697884 TI - Photoperiod Modulates Fast Delayed Rectifier Potassium Currents in the Mammalian Circadian Clock. AB - One feature of the mammalian circadian clock, situated in the suprachiasmatic nucleus (SCN), is its ability to measure day length and thereby contribute to the seasonal adaptation of physiology and behavior. The timing signal from the SCN, namely the 24 hr pattern of electrical activity, is adjusted according to the photoperiod being broader in long days and narrower in short days. Vasoactive intestinal peptide and gamma-aminobutyric acid play a crucial role in intercellular communication within the SCN and contribute to the seasonal changes in phase distribution. However, little is known about the underlying ionic mechanisms of synchronization. The present study was aimed to identify cellular mechanisms involved in seasonal encoding by the SCN. Mice were adapted to long day (light-dark 16:8) and short-day (light-dark 8:16) photoperiods and membrane properties as well as K+ currents activity of SCN neurons were measured using patch-clamp recordings in acute slices. Remarkably, we found evidence for a photoperiodic effect on the fast delayed rectifier K+ current, that is, the circadian modulation of this ion channel's activation reversed in long days resulting in 50% higher peak values during the night compared with the unaltered day values. Consistent with fast delayed rectifier enhancement, duration of action potentials during the night was shortened and afterhyperpolarization potentials increased in amplitude and duration. The slow delayed rectifier, transient K+ currents, and membrane excitability were not affected by photoperiod. We conclude that photoperiod can change intrinsic ion channel properties of the SCN neurons, which may influence cellular communication and contribute to photoperiodic phase adjustment. PMID- 27697886 TI - Clinical Use of GalaFLEX in Facial and Breast Cosmetic Plastic Surgery. AB - : Resolution of ptosis is a key step to the success of many plastic surgery procedures. Ptosis is a manifestation of tissue stretch. Tissue stretch can occur as a result of the natural aging process or health of the patient, or tissue may stretch under added weight or volume, such as when implants are placed. Surgical rejuvenation of ptotic tissues is very effective and results in marked changes in the patient profile yet the tissue that resulted in the need for the procedure first place has not improved and ptosis can recur. Recent developments in long term resorbable porous materials have provided surgeons with the opportunity to experiment with tissue reinforcement in plastic surgery procedures. These new materials have a low profile, rapid tissue integration, and a long-term strength retention profile. Long-term resorbable scaffolds such as poly-4-hydroxybutyrate (P4HB) natural scaffold (GalaFLEX scaffold, Galatea Surgical, Inc., Lexington, MA) have shown promise for a host of plastic surgery indications. This article presents clinical experience with GalaFLEX for soft tissue reinforcement in three different clinical applications; including the reinforcement of the superficial muscular aponeurotic system (SMAS) in minimally invasive facelift, reinforcement of the skin envelope in mastopexy, and reinforcement of the breast capsule (pocket) in revisional breast surgery. Soft tissue reinforcement has been shown to provide increased mechanical strength as well as improved maintenance of postoperative results. LEVEL OF EVIDENCE: 5 Therapeutic. PMID- 27697882 TI - Fructose intake and risk of gout and hyperuricemia: a systematic review and meta analysis of prospective cohort studies. AB - BACKGROUND: The prevalence of hyperuricemia and gout has increased in recent decades. The role of dietary fructose in the development of these conditions remains unclear. OBJECTIVE: To conduct a systematic review and meta-analysis of prospective cohort studies investigating the association fructose consumption with incident gout and hyperuricemia. DESIGN: MEDLINE, EMBASE and the Cochrane Library were searched (through September 2015). We included prospective cohort studies that assessed fructose consumption and incident gout or hyperuricemia. 2 independent reviewers extracted relevant data and assessed study quality using the Newcastle-Ottawa Scale. We pooled natural-log transformed risk ratios (RRs) using the generic inverse variance method. Interstudy heterogeneity was assessed (Cochran Q statistic) and quantified (I2 statistic). The overall quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: 2 studies involving 125 299 participants and 1533 cases of incident gout assessed the association between fructose consumption and incident gout over an average of 17 years of follow-up. No eligible studies assessed incident hyperuricemia as an outcome. Fructose consumption was associated with an increase in the risk of gout (RR=1.62, 95% CI 1.28 to 2.03, p<0.0001) with no evidence of interstudy heterogeneity (I2=0%, p=0.33) when comparing the highest (>11.8% to >11.9% total energy) and lowest (<6.9% to <7.5% total energy) quantiles of consumption. LIMITATIONS: Despite a dose-response gradient, the overall quality of evidence as assessed by GRADE was low, due to indirectness. There were only two prospective cohort studies involving predominantly white health professionals that assessed incident gout, and none assessed hyperuricemia. CONCLUSIONS: Fructose consumption was associated with an increased risk of developing gout in predominantly white health professionals. More prospective studies are necessary to understand better the role of fructose and its food sources in the development of gout and hyperuricemia. PROTOCOL REGISTRATION NUMBER: NCT01608620. PMID- 27697887 TI - Alloplastic Soft Tissue Support: An Overview and Clinical Experience. PMID- 27697888 TI - Do Processing Methods Make a Difference in Acellular Dermal Matrix Properties? AB - BACKGROUND: The use of acellular dermal matrices (ADMs) has become the standard of practice in many reconstructive and aesthetic surgical applications. Different methods used to prepare the allograft tissue for surgical use can alter the ADMs natural properties. Aseptic processing has been shown to retain the natural properties of ADMs more favorably than terminally sterilized ADMs. Terminal sterilization has been historically linked to alteration of biological materials. In vitro work was conducted to compare ADM processing methods. OBJECTIVES: Characterize aseptically processed ADMs and compare cell-matrix interaction characteristics to terminally sterilized ADMs. METHODS: Two aseptically processed ADMs, FlexHD Pliable and BellaDerm, were characterized via histological evaluation, biomechanical integrity, enzymatic degradation, and in vitro cell studies. FlexHD Pliable was compared to Alloderm Ready-to-Use (RTU). RESULTS: Histological evaluation revealed that FlexHD Pliable had a uniform, open structure compared to BellaDerm. Mechanical characterization demonstrated that BellaDerm had higher strength and stiffness compared to FlexHD Pliable, which maintained higher elasticity. Immunohistochemical analysis verified that key matrix proteins remained intact after aseptic processing. Cell studies found that fibroblasts attached more readily, and proliferated faster on FlexHD Pliable compared to BellaDerm. Additionally, fibroblasts infiltrated into FlexHD Pliable from both sides and on the dermal side in BellaDerm and produced an abundance of multi-layered matrix proteins (collagen, fibronectin) when compared to AlloDerm RTU which was sparse. CONCLUSIONS: Aseptically processed FlexHD Pliable and BellaDerm provide a suitable, biocompatible option for tissue repair and regeneration in aesthetic and reconstructive surgical applications.

AB - CONTEXT: Posterior shoulder instability has become more frequently recognized and treated as a unique subset of shoulder instability, especially in the military. Posterior shoulder pathology may be more difficult to accurately diagnose than its anterior counterpart, and commonly, patients present with complaints of pain rather than instability. "Posterior instability" may encompass both dislocation and subluxation, and the most common presentation is recurrent posterior subluxation. Arthroscopic and open treatment techniques have improved as understanding of posterior shoulder instability has evolved. EVIDENCE ACQUISITION: Electronic databases including PubMed and MEDLINE were queried for articles relating to posterior shoulder instability. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 4. RESULTS: In low-demand patients, nonoperative treatment of posterior shoulder instability should be considered a first line of treatment and is typically successful. Conservative treatment, however, is commonly unsuccessful in active patients, such as military members. Those patients with persistent shoulder pain, instability, or functional limitations after a trial of conservative treatment may be considered surgical candidates. Arthroscopic posterior shoulder stabilization has demonstrated excellent clinical outcomes, high patient satisfaction, and low complication rates. Advanced techniques may be required in select cases to address bone loss, glenoid dysplasia, or revision. CONCLUSION: Posterior instability represents about 10% of shoulder instability and has become increasingly recognized and treated in military members. Nonoperative treatment is commonly unsuccessful in active patients, and surgical stabilization can be considered in patients who do not respond. Isolated posterior labral repairs constitute up to 24% of operatively treated labral repairs in a military population. Arthroscopic posterior stabilization is typically considered as first-line surgical treatment, while open techniques may be required in complex or revision settings.

AB - Proteus mirabilis and Pseudomonas aeruginosa are common pathogens that often form biofilms together in catheter-associated urinary tract infections (CAUTI). However, the interactions between these two species in biofilms are largely unknown. P. mirabilis induces ureolytic biomineralization that substantially modifies key biofilm properties including morphology, persistence, and recalcitrance to antimicrobial therapy. These processes are well known to complicate CAUTI, but the consequences for colonization and persistence of P. mirabilis in polymicrobial biofilms have not been explored. Here we characterized the role of biomineralization in regulating the development of P. mirabilis and P. aeruginosa dual-species biofilms. Time-series observations revealed that the dominance of P. mirabilis was synchronized with mineral formation in the biofilm. After 24 hours of development, the dual-species biofilm was dominated by P. mirabilis, and the distribution of P. mirabilis biomass was strongly correlated with the mineral fraction of the biofilm. Conversely, dual-species growth without biomineralization yielded strikingly different patterns in the biofilm, with P. aeruginosa dominating the biofilm biomass. These results show that biomineralization is responsible for the increased success of P. mirabilis in the polymicrobial biofilm. Since biofilm biomineralization commonly occurs in diverse clinical, natural and engineered systems, these findings imply that biomineralization could broadly influence the microbial ecology of multispecies biofilms. PMID- 27697890 TI - Sex Differences in Time to Return-to-Play Progression After Sport-Related Concussion. AB - BACKGROUND: Recently, female sports participation has increased, and there is a tendency for women to experience more symptoms and variable presentation after sport-related concussion (SRC). The purpose of this study was to determine whether sex differences exist in time to begin a return-to-play (RTP) progression after an initial SRC. HYPOTHESIS: After initial SRC, female athletes (11-20 years old) would take longer to begin an RTP progression compared with age-matched male athletes. STUDY DESIGN: Retrospective cohort study. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 579 participants (365 males [mean age, 15.0 +/- 1.7 years], 214 females [mean age, 15.2 +/- 1.5 years]), including middle school, high school, and collegiate athletes who participated in various sports and experienced an initial SRC were included and underwent retrospective chart review. The following information was collected: sex, age at injury, sport, history of prior concussion, date of injury, and date of initiation of RTP progression. Participants with a history of more than 1 concussion or injury sustained from non-sport-related activity were excluded. RESULTS: Despite American football having the greatest percentage (49.2%) of sport participation, female athletes took significantly longer to start an RTP progression after an initial SRC (29.1 +/- 26.3 days) compared with age-matched male athletes (22.7 +/ 18.3 days; P = 0.002). CONCLUSION: On average, female athletes took approximately 6 days longer to begin an RTP progression compared with age-matched male athletes. This suggests that sex differences exist between athletes, aged 11 to 20 years, with regard to initiation of an RTP progression after SRC. CLINICAL RELEVANCE: Female athletes may take longer to recover after an SRC, and therefore, may take longer to return to sport. Sex should be considered as part of the clinical decision-making process when determining plan of care for this population. PMID- 27697893 TI - Erratum. AB - McWilliams, N. (2016). Training Analysts at William Alanson White. Journal of the American Psychoanalytic Association 64(4):NP12. (Original doi: 10.1177/0003065116667506 ). PMID- 27697894 TI - Finding Control Cases and Maintaining Immersion: Challenges and Opportunities. AB - Given that surveys, as well as frequent observations by institute faculty, indicate that many candidates have difficulty finding control cases and maintaining immersion and that many graduate analysts face similar challenges, it would seem that psychoanalytic training does not prepare candidates adequately for finding patients and practicing analysis while in training and, for many, after they have graduated. Although external challenges are formidable, it is by identifying and making use of internal challenges to finding cases that candidates can develop an analytic mind: the identity, approach, and skills necessary not only to graduate but to have the choice to practice clinical psychoanalysis post-graduation. Some of the internal challenges and their manifestations in different phases of initiating analysis (referrals, initial consultation, recommendation) are discussed and two detailed examples are offered to illustrate the productive use of candidates' countertransferences in finding cases and maintaining immersion. Finally, recommendations for institutional solutions are provided. PMID- 27697895 TI - Associations with resident physicians' early adoption of electronic cigarettes for smoking cessation. AB - BACKGROUND: Use of the electronic cigarette for nicotine delivery has increased dramatically in recent years. Information continues to emerge on its role as a smoking cessation aid, but little is known about resident physician use of the device in clinical practice. METHODS: In 2015, an electronic survey was administered to resident physicians in one healthcare system in Columbus, Ohio. The survey included questions about personal smoking exposure, knowledge, beliefs, attitudes about electronic cigarettes and early adoption of electronic cigarettes with patients. Data were dichotomised based on a 'stages of change' model that assessed resident physician adoption of electronic cigarettes for therapeutic use. Data were analysed through chi2 tests and logistic regression using ORs and 95% CIs. RESULTS: Of 338 residents, 142 (42%) responded. Of all residents, 25 (17.7%) reported that they have been recommending electronic cigarettes to their patients for the past 6 months or longer. In the multivariate model, residents >=postgraduate year (PGY)-3 (OR=3.68, 95% CI 1.20 to 11.29), peer-reviewed article exposure (OR=6.65, 95% CI 1.56 to 28.38) and the view that addictive potential is definitely or somewhat less than traditional cigarettes (OR=5.05, 95% CI 1.48 to 17.24) were associated with recommendation of electronic cigarettes. CONCLUSIONS: Few residents report recommending electronic cigarettes to patients who smoke. These residents consider the electronic cigarette less addicting than traditional cigarettes, supporting harm reduction strategies over strict abstinence. Most residents require further evidence-based education on efficacy and long-term safety of electronic cigarettes before recommending to their patients. PMID- 27697896 TI - Why do doctors choose to leave core medical training? PMID- 27697897 TI - Factors associated with subluxation in mallet fracture. AB - : Radiographs and medical record of all adult patients with a mallet fracture in three hospitals between 2004 and 2014 were reviewed. International Classification of Diseases, Ninth Revision (ICD-9) codes and text search in radiographic reports were used to identify all acute patients with potential mallet fractures in our institutional database. Manually checking, 392 true mallet fractures were identified among them, 78 had subluxation at the time of diagnosis and 19 had subluxation at a later time point during treatment. Fragment size, fragment displacement, and interval between injury and treatment were associated with initial and late subluxation. Subluxation was not observed when the fracture size was less than 39% of the total articular surface. For each 1% increase in total articular surface involvement in fractures with more than 39% involvement, the risk of subluxation increased by 4% and for each 1% of displacement, the risk of subluxation increased by 4%. LEVEL OF EVIDENCE: IV. PMID- 27697898 TI - Comparison of distal radius fracture intra-articular step reduction with volar locking plates and K wires: a retrospective review of quality and maintenance of fracture reduction. AB - : This study investigated the accuracy and maintenance of reduction of intra articular steps achieved with closed reduction and percutaneous K wires and open reduction and a volar locking plate for the treatment of intra-articular distal radius fractures. We performed a retrospective review of 359 patients with an intra-articular fracture of their distal radius. Multivariate linear regression was undertaken to investigate the influence of multiple variables such as age, gender, initial displacement and treatment method on reduction despite differences between groups. A total of 36% of patients treated with K wires and 29% with volar locking plate had a step greater than or equal to 1 mm present on the first post-operative radiograph. A total of 23% treated with K wires and 28% with volar locking plate had a residual step of 1 mm or more on the last available radiograph. There was no difference identified between the two techniques for quality of initial reduction or persisting step on the last available radiographs. Step behaviour and further reduction of step post operatively was similar for both treatment methods. Initial displacement and increased age influenced initial reduction. Initial fracture displacement shown radiologically was the only variable identified that influenced the persistence of a step on post-operative radiographs. LEVEL OF EVIDENCE: IV. PMID- 27697899 TI - Somatostatin analogues in acromegaly and gastroenteropancreatic neuroendocrine tumours: past, present and future. AB - Acromegaly is a hormonal disorder that arises when the pituitary gland secretes excess growth hormone (GH), which in turn stimulates a concomitant increase in serum insulin-like growth factor 1 (IGF-1) levels. Gastroenteropancreatic neuroendocrine tumours (GEP-NET) constitute a heterogeneous group of tumours that can secrete serotonin and a variety of peptide hormones that may cause characteristic symptoms known as carcinoid syndrome or other symptoms and hormonal hypersecretion syndromes depending on the tumour's site of origin. Current medical therapy for the treatment of acromegaly and GEP-NET involves the administration of somatostatin analogues that effectively suppress excess hormone secretion. After its discovery in 1979, octreotide became the first synthetic biologically stable somatostatin analogue with a short-acting formulation of octreotide introduced into clinical practice in the late 1980s. Lanreotide, another somatostatin analogue, became available in the mid-1990s initially as a prolonged-release formulation administered every 10 or 14 days. Long-acting release formulations of both octreotide (Sandostatin LAR and Novartis) and lanreotide (Somatuline Autogel, Ipsen), based on microparticle and nanoparticle drug-delivery technologies, respectively, were later developed, which allowed for once-monthly administration and improved convenience. First-generation somatostatin analogues remain one of the cornerstones of medical therapy in the management of pituitary and GEP-NET hormone hypersecretion, with octreotide having the longest established efficacy and safety profile of the somatostatin analogue class. More recently, pasireotide (Signifor), a next-generation multireceptor-targeted somatostatin analogue, has emerged as an alternative therapeutic option for the treatment of acromegaly. This review summarizes the development and clinical success of somatostatin analogues. PMID- 27697900 TI - mTOR inhibitors response and mTOR pathway in pancreatic neuroendocrine tumors. AB - Medical therapy of pancreatic neuroendocrine tumors (P-NET) may take advantage of Everolimus treatment. However, the extent of therapeutic response cannot be predicted. This study was aimed to identify the possible predictive markers of response to Everolimus in P-NET. We found that Everolimus reduced the cell viability and induced apoptosis in primary cultures of 6 P-NET (P-NET-R), where the proliferative and antiapoptotic effects of IGF1 were blocked by Everolimus. On the contrary, 14 P-NET primary cultures (P-NET-NR) were resistant to Everolimus and IGF1, suggesting an involvement of PI3K/AKT/mTOR pathway in the mechanism of resistance. The response to Everolimus in vitro was associated with an active AKT/mTOR pathway and seemed to be associated with a greater clinical aggressiveness. In addition, a patient sensitive to Everolimus in vitro was sensitive to this drug in vivo also and showed a positive p-AKT immunohistochemistry (IHC) at tissue level. Similarly, a patient resistant to Everolimus treatment after surgery was not sensitive to the drug in vitro and had a negative p-AKT IHC staining. Therefore, present data confirm that P-NET primary cultures may be considered a model for testing medical treatment efficacy and that IHC characterization of p-AKT might help in identifying human P-NET who can benefit from Everolimus treatment. These data encourage conducting a prospective multicenter study involving different groups of P-NET patients treated with Everolimus. PMID- 27697901 TI - Cytokinin acts through the auxin influx carrier AUX1 to regulate cell elongation in the root. AB - Hormonal interactions are crucial for plant development. In Arabidopsis, cytokinins inhibit root growth through effects on cell proliferation and cell elongation. Here, we define key mechanistic elements in a regulatory network by which cytokinin inhibits root cell elongation in concert with the hormones auxin and ethylene. The auxin importer AUX1 functions as a positive regulator of cytokinin responses in the root; mutation of AUX1 specifically affects the ability of cytokinin to inhibit cell elongation but not cell proliferation. AUX1 is required for cytokinin-dependent changes of auxin activity in the lateral root cap associated with the control of cell elongation. Cytokinin regulates root cell elongation through ethylene-dependent and -independent mechanisms, both hormonal signals converging on AUX1 as a regulatory hub. An autoregulatory circuit is identified involving the control of ARR10 and AUX1 expression by cytokinin and auxin, this circuit potentially functioning as an oscillator to integrate the effects of these two hormones. Taken together, our results uncover several regulatory circuits controlling interactions of cytokinin with auxin and ethylene, and support a model in which cytokinin regulates shootward auxin transport to control cell elongation and root growth. PMID- 27697902 TI - Demethylation of ERECTA receptor genes by IBM1 histone demethylase affects stomatal development. AB - DNA methylation and histone modifications interact to modulate gene expression in biological organisms. The histone demethylase IBM1 suppresses DNA methylation and gene silencing, primarily by targeting genic regions in the Arabidopsis genome. The chromatin regulator EDM2 is also required for prevention of genic DNA methylation because it maintains IBM1 expression by promoting IBM1 mRNA distal polyadenylation. Loss-of-function ibm1 and edm2 mutant plants display a wide range of developmental defects, but little is known about which developmentally important genes are regulated by IBM1 and EDM2. Here, we show that both ibm1 and edm2 mutants display defects in production of stomatal lineage cells, which is linked to DNA hypermethylation of the ERECTA family genes, including ER, ERL1 and ERL2 Stomatal phenotypes and DNA methylation levels of ER genes in ibm1 and edm2 mutants are restored by mutations in the genes encoding the histone methyltransferase KYP and DNA methyltransferase CMT3. Our data demonstrate that a specific plant developmental context is influenced by IBM1-regulated histone modification and DNA methylation on the gene body region of the ERECTA receptors. PMID- 27697905 TI - Boronic acid treatment phenocopies monopteros by affecting PIN1 membrane stability and polar auxin transport in Arabidopsis thaliana embryos. AB - Several observations suggest that the micronutrient boron (B) has a stabilising role in the plasma membrane (PM), supporting functions in PM-linked (hormone) signalling processes. However, this role is poorly characterised. Here we show treatment with boronic acids, specific competitors of B, phenocopies the Arabidopsis thaliana rootless pattern mutant monopteros. At least in part, this is caused by phenylboronic acid (PBA)-induced internalisation of the membrane localised auxin efflux carrier PINFORMED1 (PIN1) in the early embryo. PIN1 internalisation interrupts the feedback signal transduction cascade involving the phytohormone auxin, PIN1 and the transcription factor gene MONOPTEROS This entails several effects, including abnormal development of vascular cell precursors, suppression of MONOPTEROS downstream targets and loss of the root auxin maximum - essential signals for root meristem development. While PIN1 is internalised, we observe a differential effect of PBA on other proteins, which are either unaffected, internalised or, as in the case of the B transporter BOR1, stabilised at the PM. These findings suggest a competition of PBA with B for plant membrane proteins and might shed light on the function of B at the PM. PMID- 27697903 TI - Reversible optogenetic control of kinase activity during differentiation and embryonic development. AB - A limited number of signaling pathways are repeatedly used to regulate a wide variety of processes during development and differentiation. The lack of tools to manipulate signaling pathways dynamically in space and time has been a major technical challenge for biologists. Optogenetic techniques, which utilize light to control protein functions in a reversible fashion, hold promise for modulating intracellular signaling networks with high spatial and temporal resolution. Applications of optogenetics in multicellular organisms, however, have not been widely reported. Here, we create an optimized bicistronic optogenetic system using Arabidopsis thaliana cryptochrome 2 (CRY2) protein and the N-terminal domain of cryptochrome-interacting basic-helix-loop-helix (CIBN). In a proof-of principle study, we develop an optogenetic Raf kinase that allows reversible light-controlled activation of the Raf/MEK/ERK signaling cascade. In PC12 cells, this system significantly improves light-induced cell differentiation compared with co-transfection. When applied to Xenopus embryos, this system enables blue light-dependent reversible Raf activation at any desired developmental stage in specific cell lineages. Our system offers a powerful optogenetic tool suitable for manipulation of signaling pathways with high spatial and temporal resolution in a wide range of experimental settings. PMID- 27697908 TI - Sensitivity and Bias in the Resolution of Stream-Bounce Stimuli. AB - The audiovisual stream-bounce effect refers to the resolution of ambiguous motion sequences as streaming or bouncing depending on the presence or absence of a sound. We used a novel experimental design and signal detection theory (SDT) to determine its sensory or decisional origins. To account for issues raised by Witt et al. on the interpretation of SDT results, we devised a pure signal detection (as opposed to signal discrimination) paradigm and measured participants' sensitivity and criterion when detecting a weak tone concurrent with objectively streaming or bouncing visual displays. We observed no change in sensitivity but a significant change in criterion with participants' criterion more liberal with bouncing targets than for streaming targets with. In a second experiment, we tasked participants with detecting a weak tone in noise while viewing an ambiguous motion sequence. They also indicated whether the targets appeared to stream or bounce. Participants' reported equivalent, mostly bouncing responses for hit and false alarm trials, and equivalent, mostly streaming responses for correct rejection and miss trials. Further, differences in participants' sensitivity and criterion measures for detecting tones in subjectively streaming compared to subjectively bouncing targets were inconsistent with sensory factors. These results support a decisional account of the sound-induced switch from mostly streaming to mostly bouncing responses in audiovisual stream-bounce displays. PMID- 27697906 TI - Nuclei migrate through constricted spaces using microtubule motors and actin networks in C. elegans hypodermal cells. AB - Cellular migrations through constricted spaces are a crucial aspect of many developmental and disease processes including hematopoiesis, inflammation and metastasis. A limiting factor in these events is nuclear deformation. Here, we establish an in vivo model in which nuclei can be visualized while moving through constrictions and use it to elucidate mechanisms for nuclear migration. C. elegans hypodermal P-cell larval nuclei traverse a narrow space that is about 5% their width. This constriction is blocked by fibrous organelles, structures that pass through P cells to connect the muscles to cuticle. Fibrous organelles are removed just prior to nuclear migration, when nuclei and lamins undergo extreme morphological changes to squeeze through the space. Both actin and microtubule networks are organized to mediate nuclear migration. The LINC complex, consisting of the SUN protein UNC-84 and the KASH protein UNC-83, recruits dynein and kinesin-1 to the nuclear surface. Both motors function in P-cell nuclear migration, but dynein, functioning through UNC-83, plays a more central role as nuclei migrate towards minus ends of polarized microtubule networks. Thus, the nucleoskeleton and cytoskeleton are coordinated to move nuclei through constricted spaces. PMID- 27697904 TI - The stage-dependent roles of Ldb1 and functional redundancy with Ldb2 in mammalian retinogenesis. AB - The Lim domain-binding proteins are key co-factor proteins that assemble with LIM domains of the LMO/LIM-HD family to form functional complexes that regulate cell proliferation and differentiation. Using conditional mutagenesis and comparative phenotypic analysis, we analyze the function of Ldb1 and Ldb2 in mouse retinal development, and demonstrate overlapping and specific functions of both proteins. Ldb1 interacts with Lhx2 in the embryonic retina and both Ldb1 and Ldb2 play a key role in maintaining the pool of retinal progenitor cells. This is accomplished by controlling the expression of the Vsx2 and Rax, and components of the Notch and Hedgehog signaling pathways. Furthermore, the Ldb1/Ldb2-mediated complex is essential for generation of early-born photoreceptors through the regulation of Rax and Crx. Finally, we demonstrate functional redundancy between Ldb1 and Ldb2. Ldb1 can fully compensate the loss of Ldb2 during all phases of retinal development, whereas Ldb2 alone is sufficient to sustain activity of Lhx2 in both early- and late-stage RPCs and in Muller glia. By contrast, loss of Ldb1 disrupts activity of the LIM domain factors in neuronal precursors. An intricate regulatory network exists that is mediated by Ldb1 and Ldb2, and promotes RPC proliferation and multipotency; it also controls specification of mammalian retina cells. PMID- 27697910 TI - Do You Hear More Piano or Drum Sounds? An Auditory Version of the Solitaire Illusion. AB - The solitaire illusion is an illusion of numerosity proposed by Frith and Frith. In the original version, an apparent number of elements was determined by the spatial arrangement of two kinds of elements (black and white marbles). In our study, an auditory version of the solitaire illusion was demonstrated. Participants were asked to judge if they perceived more drum or piano sounds. When half of the piano tones were perceived as lower in pitch than a drum sound and the other half higher, piano tones appeared to be arranged in small units, leading to numerosity underestimation. Conversely, when all piano tones were perceived to be higher in pitch than the drum sounds, they appeared to be arranged in a single large unit, leading to numerosity overestimation. Comparable to the visual version of the solitaire illusion, the clustering seems to be determined by Gestalt principles. In our auditory version, a clear reversal of the illusion (numerosity overestimation or underestimation) was observed when piano tones appeared to be arranged in a single large cluster or in several small clusters, respectively. PMID- 27697907 TI - A network of conserved formins, regulated by the guanine exchange factor EXC-5 and the GTPase CDC-42, modulates tubulogenesis in vivo. AB - The C. elegans excretory cell (EC) is a powerful model for tubulogenesis, a conserved process that requires precise cytoskeletal regulation. EXC-6, an ortholog of the disease-associated formin INF2, coordinates cell outgrowth and lumen formation during EC tubulogenesis by regulating F-actin at the tip of the growing canal and the dynamics of basolateral microtubules. EXC-6 functions in parallel with EXC-5/FGD, a predicted activator of the Rho GTPase Cdc42. Here, we identify the parallel pathway: EXC-5 functions through CDC-42 to regulate two other formins: INFT-2, another INF2 ortholog, and CYK-1, the sole ortholog of the mammalian diaphanous (mDia) family of formins. We show that INFT-2 promotes F actin accumulation in the EC, and that CYK-1 inhibits INFT-2 to regulate F-actin levels and EXC-6-promoted outgrowth. As INF2 and mDia physically interact and cross-regulate in cultured cells, our work indicates that a conserved EXC-5-CDC 42 pathway modulates this regulatory interaction and that it is functionally important in vivo during tubulogenesis. PMID- 27697911 TI - Testing Alcohol Myopia Theory: Examining the Effects of Alcohol Intoxication on Simultaneous Central and Peripheral Attention. AB - The effect of alcohol intoxication on central and peripheral attention was examined as a test of Alcohol Myopia Theory (AMT). Previous research has supported AMT in the context of visual attention, but few studies have examined the effects of alcohol intoxication on central and peripheral attention. The study followed a 2 (alcohol treatment) * 2 (array size) * 2 (task type) mixed design. Forty-one participants (placebo or intoxicated) viewed an array of four or six colored circles, while simultaneously counting the flashes of a centrally presented fixation cross. Participants were instructed to prioritize flash counting accuracy. The subsequently presented colored probe matched the cued peripheral stimulus on 50% of trials. Flash counting and probe identification accuracy were recorded. There was a significant main effect of alcohol treatment on accuracy scores, as well as an alcohol treatment by task type interaction. Accuracy scores for the central flash counting task did not differ between treatment groups, but scores for peripheral probe identification were lower in the alcohol group. As predicted by AMT, alcohol impairment was greater for peripheral probe detection than for the central and prioritized flash counting task. The findings support the notion that alcohol intoxication narrows attentional focus to the central aspects of a task. PMID- 27697909 TI - Light Video Game Play is Associated with Enhanced Visual Processing of Rapid Serial Visual Presentation Targets. AB - There is mixed evidence that video game players (VGPs) may demonstrate better performance in perceptual and attentional tasks than non-VGPs (NVGPs). The rapid serial visual presentation task is one such case, where observers respond to two successive targets embedded within a stream of serially presented items. We tested light VGPs (LVGPs) and NVGPs on this task. LVGPs were better at correct identification of second targets whether they were also attempting to respond to the first target. This performance benefit seen for LVGPs suggests enhanced visual processing for briefly presented stimuli even with only very moderate game play. Observers were less accurate at discriminating the orientation of a second target within the stream if it occurred shortly after presentation of the first target, that is to say, they were subject to the attentional blink (AB). We find no evidence for any reduction in AB in LVGPs compared with NVGPs. PMID- 27697912 TI - The Influence of Olfactory Contexts on the Sequential Rating of Odor Pleasantness. AB - When we sequentially evaluate the characteristics of sensory stimuli, our evaluation of a current stimulus is influenced by those preceding it. One such effect is called hedonic contrast, whereby stimuli are rated more negatively (negative contrast) or positively (positive contrast) if they are preceded by more or less pleasant stimuli. The present study investigated the characteristics of hedonic contrast for olfaction and compared these characteristics with those of a more oft-studied modality, vision. The results from two experiments indicated that both positive and negative contrasts occurred in the sequential rating of picture pleasantness, whereas only negative contrast occurred for olfactory ratings. Notably, overrating of hedonically negative odors following a positive olfactory context was observed even when participants had already rated these same negative odors beforehand; conversely, this did not occur for positive contrast for either sense. These findings indicate that negative odors are more strongly influenced than positive ones, and the rating of positive stimuli may be adjusted to the preceding rating independent of stimulus context. The findings of this study revealed the unique characteristics of hedonic contrast for the olfactory senses. PMID- 27697913 TI - Low-Level Motion Characteristics Do Not Account for Perceptions of Stream-Bounce Stimuli. AB - The stream-bounce effect refers to a bistable motion stimulus that is interpreted as two targets either "streaming" past or "bouncing" off one another, and the manipulations that bias responses. Directional bias, according to Bertenthal et al., is an account of the effect proposing that low-level motion integration promotes streaming, and its disruption leads to bouncing, and it is sometimes cited either directly in a bottom-up fashion or indirectly under top-down control despite Sekuler and Sekuler finding evidence inconsistent with it. We tested two key aspects of the hypothesis: (a) comparable changes in speed should produce comparable disruptions and lead to similar effects; and (b) speed changes alone should disrupt integration without the need for additional more complex changes of motion. We found that target motion influences stream-bounce perception, but not as directional bias predicts. Our results support Sekuler and Sekuler and argue against the low-level motion signals driving perceptual outcomes in stream bounce displays (directly or indirectly) and point to higher level inferential processes involving perceptual history and expectation. Directional bias as a mechanism should be abandoned and either another specific bottom-up process must be proposed and tested or consideration should be given to top-down factors alone driving the effect. PMID- 27697914 TI - A Common Mechanism for Perceptual Reversals in Motion-Induced Blindness, the Troxler Effect, and Perceptual Filling-In. AB - Several striking visual phenomena involve a physically present stimulus that alternates between being perceived and being "invisible." For example, motion induced blindness, the Troxler effect, and perceptual filling-in all consist of subjective alternations where an item repeatedly changes from being seen to unseen. In the present study, we explored whether these three specific visual phenomena share any commonalities in their alternation rates and patterns to better understand the mechanisms of each. Data from 69 individuals revealed moderate to strong correlations across the three phenomena for the number of perceptual disappearances and the accumulated duration of the disappearances. Importantly, these effects were not correlated with eye movement patterns (saccades) assessed through eye tracking, differences in motion sensitivity as indexed by dot coherence and speed perception thresholds, or simple reaction time abilities. Principal component analyses revealed a single component that explained 67% of the variance for the number of perceptual reversals and 60% for the accumulated duration of the disappearances. The temporal dynamics of illusory disappearances was also compared for each phenomenon, and normalized durations of disappearances were well fit by a gamma distribution with similar shape parameters for each phenomenon, suggesting that they may be driven by a single oscillatory mechanism.

AB - To date, sterylglucosides have been reported to be present in various fungi, plants, and animals. In bacteria, such as Helicobacter pylori, proton NMR spectral analysis of isolated 1-O-cholesteryl-beta-d-glucopyranoside (GlcChol) demonstrated the presence of an alpha-glucosidic linkage. By contrast, in animals, no detailed structural analysis of GlcChol has been reported, in part because animal-derived samples contain a high abundance of glucosylceramides (GlcCers)/galactosylceramides, which exhibit highly similar chromatographic behavior to GlcChol. A key step in vertebrate GlcChol biosynthesis is the transglucosylation reaction catalyzed by glucocerebrosidase (GBA)1 or GBA2, utilizing GlcCer as a glucose donor. These steps are expected to produce a beta glucosidic linkage. Impaired GBA1 and GBA2 function is associated with neurological disorders, such as cerebellar ataxia, spastic paraplegia, and Parkinson's disease. Utilizing a novel three-step chromatographic procedure, we prepared highly enriched GlcChol from embryonic chicken brain, allowing complete structural confirmation of the beta-glucosidic linkage by 1H-NMR analysis. Unexpectedly, during purification, two additional sterylglucoside fractions were isolated. NMR and GC/MS analyses confirmed that the plant-type sitosterylglucoside in vertebrate brain is present throughout embryonic development. The aglycon structure of the remaining sterylglucoside (GSX-2) remains elusive due to its low abundance. Together, our results uncovered unexpected aglycon heterogeneity of sterylglucosides in vertebrate brain. PMID- 27697917 TI - Editorial: Uteroplacental mingling: who's kissing uNK?

In this issue, Albrecht et. al. (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201603108) demonstrate via high-speed single-particle tracking and superresolution microscopy that lipid-anchored molecules in the axon initial segment are confined to membrane domains separated by periodically spaced actin rings. PMID- 27697922 TI - Nuclear envelope rupture is induced by actin-based nucleus confinement. AB - Repeated rounds of nuclear envelope (NE) rupture and repair have been observed in laminopathy and cancer cells and result in intermittent loss of nucleus compartmentalization. Currently, the causes of NE rupture are unclear. Here, we show that NE rupture in cancer cells relies on the assembly of contractile actin bundles that interact with the nucleus via the linker of nucleoskeleton and cytoskeleton (LINC) complex. We found that the loss of actin bundles or the LINC complex did not rescue nuclear lamina defects, a previously identified determinant of nuclear membrane stability, but did decrease the number and size of chromatin hernias. Finally, NE rupture inhibition could be rescued in cells treated with actin-depolymerizing drugs by mechanically constraining nucleus height. These data suggest a model of NE rupture where weak membrane areas, caused by defects in lamina organization, rupture because of an increase in intranuclear pressure from actin-based nucleus confinement. PMID- 27697923 TI - The Ska complex promotes Aurora B activity to ensure chromosome biorientation. AB - Chromosome biorientation and accurate segregation rely on the plasticity of kinetochore-microtubule (KT-MT) attachments. Aurora B facilitates KT-MT dynamics by phosphorylating kinetochore proteins that are critical for KT-MT interactions. Among the substrates whose microtubule and kinetochore binding is curtailed by Aurora B is the spindle and kinetochore-associated (Ska) complex, a key factor for KT-MT stability. Here, we show that Ska is not only a substrate of Aurora B, but is also required for Aurora B activity. Ska-deficient cells fail to biorient and display chromosome segregation errors underlying suppressed KT-MT turnover. These defects coincide with KNL1-Mis12-Ndc80 network hypophosphorylation, reduced mitotic centromere-associated kinesin localization, and Aurora B T-loop phosphorylation at kinetochores. We further show that Ska requires its microtubule-binding capability to promote Aurora B activity in cells and stimulates Aurora B catalytic activity in vitro. Finally, we show that protein phosphatase 1 counteracts Aurora B activity to enable Ska kinetochore accumulation once biorientation is achieved. We propose that Ska promotes Aurora B activity to limit its own microtubule and kinetochore association and to ensure that KT-MT dynamics and stability fall within an optimal balance for biorientation.

AB - Proper dynamic regulation of the spindle is essential for successful cell division. However, the molecular mechanisms that regulate spindle dynamics in mitosis are not fully understood. In this study, we show that Cullin 5 interacting suppressor of cytokine signaling box protein ASB7 ubiquitinates DDA3, a regulator of spindle dynamics, thereby targeting it for proteasomal degradation. The presence of microtubules (MTs) prevented the ASB7-DDA3 interaction, thus stabilizing DDA3. Knockdown of ASB7 decreased MT polymerization and increased the proportion of cells with unaligned chromosomes, and this phenotype was rescued by deletion of DDA3. Collectively, these data indicate that ASB7 plays a crucial role in regulating spindle dynamics and genome integrity by controlling the expression of DDA3. PMID- 27697927 TI - Nuclear envelope rupture: Actin fibers are putting the squeeze on the nucleus. AB - Cells exhibit transient nuclear envelope ruptures during interphase, but the responsible biophysical processes remain unclear. In this issue, Hatch and Hetzer (2016. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201603053) show that actin fibers constrict the nucleus, causing chromatin protrusions and nuclear membrane ruptures at sites with nuclear lamina defects. PMID- 27697925 TI - Simple rules for passive diffusion through the nuclear pore complex. AB - Passive macromolecular diffusion through nuclear pore complexes (NPCs) is thought to decrease dramatically beyond a 30-60-kD size threshold. Using thousands of independent time-resolved fluorescence microscopy measurements in vivo, we show that the NPC lacks such a firm size threshold; instead, it forms a soft barrier to passive diffusion that intensifies gradually with increasing molecular mass in both the wild-type and mutant strains with various subsets of phenylalanine glycine (FG) domains and different levels of baseline passive permeability. Brownian dynamics simulations replicate these findings and indicate that the soft barrier results from the highly dynamic FG repeat domains and the diffusing macromolecules mutually constraining and competing for available volume in the interior of the NPC, setting up entropic repulsion forces. We found that FG domains with exceptionally high net charge and low hydropathy near the cytoplasmic end of the central channel contribute more strongly to obstruction of passive diffusion than to facilitated transport, revealing a compartmentalized functional arrangement within the NPC. PMID- 27697928 TI - Nanoscopic compartmentalization of membrane protein motion at the axon initial segment. AB - The axon initial segment (AIS) is enriched in specific adaptor, cytoskeletal, and transmembrane molecules. During AIS establishment, a membrane diffusion barrier is formed between the axonal and somatodendritic domains. Recently, an axonal periodic pattern of actin, spectrin, and ankyrin forming 190-nm-spaced, ring-like structures has been discovered. However, whether this structure is related to the diffusion barrier function is unclear. Here, we performed single-particle tracking time-course experiments on hippocampal neurons during AIS development. We analyzed the mobility of lipid-anchored molecules by high-speed single particle tracking and correlated positions of membrane molecules with the nanoscopic organization of the AIS cytoskeleton. We observe a strong reduction in mobility early in AIS development. Membrane protein motion in the AIS plasma membrane is confined to a repetitive pattern of ~190-nm-spaced segments along the AIS axis as early as day in vitro 4, and this pattern alternates with actin rings. Mathematical modeling shows that diffusion barriers between the segments significantly reduce lateral diffusion along the axon. PMID- 27697926 TI - Opposing roles for SNAP23 in secretion in exocrine and endocrine pancreatic cells. AB - The membrane fusion of secretory granules with plasma membranes is crucial for the exocytosis of hormones and enzymes. Secretion disorders can cause various diseases such as diabetes or pancreatitis. Synaptosomal-associated protein 23 (SNAP23), a soluble N-ethyl-maleimide sensitive fusion protein attachment protein receptor (SNARE) molecule, is essential for secretory granule fusion in several cell lines. However, the in vivo functions of SNAP23 in endocrine and exocrine tissues remain unclear. In this study, we show opposing roles for SNAP23 in secretion in pancreatic exocrine and endocrine cells. The loss of SNAP23 in the exocrine and endocrine pancreas resulted in decreased and increased fusion of granules to the plasma membrane after stimulation, respectively. Furthermore, we identified a low molecular weight compound, MF286, that binds specifically to SNAP23 and promotes insulin secretion in mice. Our results demonstrate opposing roles for SNAP23 in the secretion mechanisms of the endocrine and exocrine pancreas and reveal that the SNAP23-binding compound MF286 may be a promising drug for diabetes treatment. PMID- 27697929 TI - A human in vitro model of Duchenne muscular dystrophy muscle formation and contractility. AB - Tongue weakness, like all weakness in Duchenne muscular dystrophy (DMD), occurs as a result of contraction-induced muscle damage and deficient muscular repair. Although membrane fragility is known to potentiate injury in DMD, whether muscle stem cells are implicated in deficient muscular repair remains unclear. We hypothesized that DMD myoblasts are less sensitive to cues in the extracellular matrix designed to potentiate structure-function relationships of healthy muscle. To test this hypothesis, we drew inspiration from the tongue and engineered contractile human muscle tissues on thin films. On this platform, DMD myoblasts formed fewer and smaller myotubes and exhibited impaired polarization of the cell nucleus and contractile cytoskeleton when compared with healthy cells. These structural aberrations were reflected in their functional behavior, as engineered tongues from DMD myoblasts failed to achieve the same contractile strength as healthy tongue structures. These data suggest that dystrophic muscle may fail to organize with respect to extracellular cues necessary to potentiate adaptive growth and remodeling. PMID- 27697931 TI - Effects of dietary fat source and supplemental lysophosphatidylcholine on performance, immune responses, and ileal nutrient digestibility in broilers fed corn/soybean meal- or corn/wheat/soybean meal-based diets. AB - Two separate experiments were conducted to investigate the effect of different fat sources and a supplemental exogenous emulsifier (lysophosphatidylcholine, LPC) on growth performance, antibody production titers, and ileal nutrient digestibility in broiler chicks fed with different basal diets. A total of 288 one-day-old Ross 308 chicks were used for each trial (6 dietary treatments based on 3 * 2 factorial arrangements of treatments in both trials) with 4 replicates of 12 birds each. Dietary treatments consisted of 3 different fat sources (soy oil, SO; soy free fatty acids, SFFA; and palm fat powder, PFP) and 2 LPC levels (0 and 0.1% of diet), which were evaluated with 2 different basal diets (corn/soybean meal-based diets in Exp. 1, or corn/wheat/soybean meal-based diets in Exp. 2). In Exp. 1, average daily feed intake (ADFI) was increased (P < 0.01) in birds fed PFP diets compared with those fed SO or SFFA diets. Although supplemental LPC decreased (P < 0.01) ADFI, the birds fed SFFA diets had the greater ADFI at the presence of LPC (fat source * LPC, P < 0.01). Dietary supplementation of LPC caused a 4.6% improvement (P < 0.001) in average daily weight gain (ADWG) and consequently improved (P < 0.01) feed conversion ratio (FCR). Supplemental LPC was more effective in increasing ADWG in SFFA-containing diets, resulted in a significant (P < 0.01) dietary fat source * LPC interaction. Dietary inclusion of LPC increased (P < 0.01) bursa weight and improved (P < 0.05) antibody production titers against sheep red blood cells and Newcastle disease virus during primary responses. Ileal digestibility of ether extract (EE) was improved (P < 0.05) in birds fed diets containing SO as compared with those fed PFP diets; dietary LPC supplementation, however, had no marked effect on ileal nutrient digestibility. In Exp. 2, ADWG was greater (P < 0.05) in birds fed SO-containing diets compared with PFP-supplemented broiler chicks. Furthermore, dietary supplementation with LPC improved (P < 0.05) FCR value by 2.1%. Relative thymus weight was greater (P < 0.05) in birds fed LPC-supplemented diets than those fed unsupplemented diets. Supplemental LPC increased (P < 0.05) Gumboro antibody titer, and the lowest antibody response was allotted to the birds fed PFP diets. The greatest (P < 0.05) EE digestibility was assigned to the birds fed SO and SFFA diets. The present findings showed that birds fed SFFA-containing diets had similar performance as SO birds, and supplemental LPC improved overall performance especially in SFFA-fed birds. PMID- 27697930 TI - Interaction between xylanase and phytase on the digestibility of corn and a corn/soy diet for broiler chickens. AB - An experiment was carried out to evaluate the digestibility and metabolizability of corn and a corn/soy-based diet with the inclusion or not of xylanase and/or phytase in broilers. In the trial, 1,120 broiler chicks were distributed according to a completely randomized experimental design, consisting of 16 treatments, with 10 replicates of 7 birds each. Treatments were evaluated following a factorial arrangement (4 * 2 * 2), with 4 xylanase levels (zero, 50, 100, or 150 fungal beta-xylanase units/kg; FXU), 2 phytase levels (zero or 1,000 phytase units/kg; FTU), and 2 diets (corn/soy or pure corn). The same basal diets were fed from one to 14 d post hatch for all birds, after which the experimental diets were provided until d 25. All birds were euthanized on d 25 for collection of ileal contents. Samples of feed, excreta, and ileal digesta were analyzed for determination of apparent ileal digestibility. The effect of xylanase on the coefficient of apparent dry matter metabolizability and apparent metabolizable energy was increased by the presence of phytase in the complete diet but not in the diet based on pure corn resulting in a diet*phytase*xylanase interaction (P < 0.01; P < 0.001, respectivaly). Equivalent effects were observed for the apparent coefficient of ileal protein digestibility in which xylanase effects were potentiated by the presence of phytase only in the complete diet, resulting in a significant 3-way interaction. In corn there was a limitation in improving digestibility when we added increasing levels of xylanase with phytase. Otherwise in the corn/soy-based diets, the enzymes were potencialized when they were added together. The fact that the effect of xylanase was enhanced by the presence of phytase in complete diets but not in pure corn may be associated with differences in substrate (arabinoxylan and/or phytate) concentration and presentation, diet nutrient balance, or other factors. It can be concluded that the interactive effects of xylanase and phytase can be substantial but may depend on the characteristics of the diet fed. PMID- 27697932 TI - Effects of dietary recombinant chlorella supplementation on growth performance, meat quality, blood characteristics, excreta microflora, and nutrient digestibility in broilers. AB - The use of chlorella as an immune stimulant to enhance nonspecific host defense mechanisms or as an antimicrobial to inhibit bacterial growth has been reported. Thus, the aim of the present study was to clarify the effect of recombinant chlorella supplementation on growth performance, meat quality, and the blood profile, excreta microflora, and nutrient digestibility in broilers. A total of 375 one-day-old ROSS 308 broilers (male and female) were allotted to 5 dietary treatments using 5 cages with 15 chicks per cage. Treatments were: 1) NC, basal diet supplemented with 1.0% E. coli fermented liquor (EFL); 2) PC1, 0.2% EFL with chlorella; 3) PC2, 1.0% EFL with chlorella; 4) T1, 0.2% EFL with chlorella (anti viral); and 5) T2, 1.0% EFL with chlorella (anti-viral). The broilers in the T2 treatment groups showed higher body weight gain (BGW) by 2.55% (P < 0.01) and lower feed conversion ratio (FCR) by 2.75% (P < 0.05) compared with those fed the control NC treatment group. Moreover, the blood contents of blood urea nitrogen (BUN), creatinine, and IgA in the broilers of the T2 treatment group were significantly increased by 28.12, 23.07, and 29.72%, respectively -more than those found in the broilers of the NC treatment group (P < 0.01). In contrast, the LDL/C in the blood from the animals in the T2 treatment group was significantly decreased by 23.23% - more than that in the blood from the NC broilers (P < 0.05). Based on these results, we suggest that the dietary supplementation of broilers with recombinant chlorella could improve their growth performance, increase the concentration of IgA and apparently metabolizable nitrogen in the blood, and decrease ammonia emissions. Therefore, our findings have important implications for the effect of recombinant chlorella supplementation through increasing the concentration of IgA and the level of metabolizable nitrogen. PMID- 27697933 TI - Gene expression of amino acid transporter in pigeon (Columbia livia) intestine during post-hatch development and its correlation with amino acid in pigeon milk. AB - This study was conducted to evaluate gene expression of the amino acid transporter in post-hatch pigeon small intestine and the association of pigeon milk amino acid with the above transporter's gene expression. A total of 48 pigeon breeding families were randomly allocated to 8 groups of 6 replicates of one parental pigeon pair and 2 squabs. Samples of pigeon milk and duodenum, jejunum, and ileum were collected on d 1, 2, 3, 4, 6, 8, 10, and 14 post hatch. The results showed that levels of crude protein (8.93 to 15.56%) were highest in pigeon milk on an air-dry basis. Amino acid content in pigeon milk remained constant in the first 4 d, declined abruptly at d 6, then increased dramatically from d 8 to 14. There was a significant effect of interaction between age and intestinal segments on those amino acid transporters gene expression. mRNA abundance of ATB0'+, SNAT-2, LAT-4, rBAT, b0'+AT, EAAT-3 and PAT-1 was highest in the ileum; B0AT1, asc-1, and IMINO were predominate in the jejunum; and CAT-1 and y+LAT2 were greatest in the duodenum. Age-related changes of amino acid transporter mRNA was inconsistent. mRNA levels of SNAT-2, rBAT, y+LAT2, b0'+AT, and EAAT-3 ascended with age, whereas that of asc-1, CAT-1, and IMINO diminished significantly. Levels of B0AT1 and PAT-1 mRNA abundance were minimized at d 6. However, few correlations were found between pigeon milk amino acid and the amino acid transporter gene expressions in squab small intestine. Our findings provide a comprehensive elaboration on ontogeny of the amino acid transporter in post hatch pigeon intestine. PMID- 27697934 TI - Infographic. Golf and health.

PMID- 27697938 TI - Evidence from prospective cohort studies does not support current dietary fat guidelines: a systematic review and meta-analysis. AB - OBJECTIVES: National dietary guidelines were introduced in 1977 and 1983, by the US and UK governments to reduce coronary heart disease (CHD) mortality by reducing dietary fat intake. Our 2016 systematic review examined the epidemiological evidence available to the dietary committees at the time; we found no support for the recommendations to restrict dietary fat. The present investigation extends our work by re-examining the totality of epidemiological evidence currently available relating to dietary fat guidelines. METHODS: A systematic review and meta-analysis of prospective cohort studies currently available, which examined the relationship between dietary fat, serum cholesterol and the development of CHD, were undertaken. RESULTS: Across 7 studies, involving 89 801 participants (94% male), there were 2024 deaths from CHD during the mean follow-up of 11.9+/-5.6 years. The death rate from CHD was 2.25%. Eight data sets were suitable for inclusion in meta-analysis; all excluded participants with previous heart disease. Risk ratios (RRs) from meta-analysis were not statistically significant for CHD deaths and total or saturated fat consumption. The RR from meta-analysis for total fat intake and CHD deaths was 1.04 (95% CI 0.98 to 1.10). The RR from meta-analysis for saturated fat intake and CHD deaths was 1.08 (95% CI 0.94 to 1.25). CONCLUSIONS: Epidemiological evidence to date found no significant difference in CHD mortality and total fat or saturated fat intake and thus does not support the present dietary fat guidelines. The evidence per se lacks generalisability for population-wide guidelines. PMID- 27697940 TI - NCI's state and community research initiative: a model for future tobacco control research. PMID- 27697941 TI - National Cancer Institute's leadership role in promoting State and Community Tobacco Control research. AB - The National Cancer Institute (NCI) has been at the vanguard of funding tobacco control research for decades with major efforts such as the Community Intervention Trial for Smoking Cessation (COMMIT) in 1988 and the American Stop Smoking Intervention Study (ASSIST) in 1991, followed by the Tobacco Research Initiative for State and Community Interventions in 1999. Most recently, in 2011, the NCI launched the State and Community Tobacco Control (SCTC) Research Initiative to address gaps in secondhand smoke policies, tax and pricing policies, mass media countermeasures, community and social norms and tobacco marketing. The initiative supported large scale research projects and time sensitive ancillary pilot studies in response to expressed needs of state and community partners. This special issue of Tobacco Control showcases exciting findings from the SCTC. In this introductory article, we provide a brief account of NCI's historical commitment to promoting research to inform tobacco control policy. PMID- 27697939 TI - The relationships between golf and health: a scoping review. AB - OBJECTIVE: To assess the relationships between golf and health. DESIGN: Scoping review. DATA SOURCES: Published and unpublished reports of any age or language, identified by searching electronic databases, platforms, reference lists, websites and from consulting experts. REVIEW METHODS: A 3-step search strategy identified relevant published primary and secondary studies as well as grey literature. Identified studies were screened for final inclusion. Data were extracted using a standardised tool, to form (1) a descriptive analysis and (2) a thematic summary. RESULTS AND DISCUSSION: 4944 records were identified with an initial search. 301 studies met criteria for the scoping review. Golf can provide moderate intensity physical activity and is associated with physical health benefits that include improved cardiovascular, respiratory and metabolic profiles, and improved wellness. There is limited evidence related to golf and mental health. The incidence of golfing injury is moderate, with back injuries the most frequent. Accidental head injuries are rare, but can have serious consequences. CONCLUSIONS: Practitioners and policymakers can be encouraged to support more people to play golf, due to associated improved physical health and mental well-being, and a potential contribution to increased life expectancy. Injuries and illnesses associated with golf have been identified, and risk reduction strategies are warranted. Further research priorities include systematic reviews to further explore the cause and effect nature of the relationships described. Research characterising golf's contribution to muscular strengthening, balance and falls prevention as well as further assessing the associations and effects between golf and mental health are also indicated.

AB - New York City, a leader in municipal tobacco control in the USA, furthered its goal of reducing the community's burden of tobacco use in 2014 by implementing Sensible Tobacco Enforcement and Tobacco 21. These policies are intended to restrict youth access and eliminate sources of cheap tobacco. Strong partnerships, substantial local data and support from the public and elected officials were key in overcoming many challenges and ensuring these policies were signed into law. PMID- 27697943 TI - Minimal intervention delivered by 2-1-1 information and referral specialists promotes smoke-free homes among 2-1-1 callers: a Texas generalisation trial. AB - BACKGROUND: Replication of intervention research is reported infrequently, limiting what we know about external validity and generalisability. The Smoke Free Homes Program, a minimal intervention, increased home smoking bans by United Way 2-1-1 callers in randomised controlled trials in Atlanta, Georgia and North Carolina. OBJECTIVE: Test the programme's generalisability-external validity in a different context. METHODS: A randomised controlled trial (n=508) of English speaking callers from smoking-discordant households (>=1 smoker and >=1 non smoker). 2-1-1 Texas/United Way HELPLINE call specialists serving the Texas Gulf Coast recruited callers and delivered three mailings and one coaching call, supported by an online tracking system. Data collectors, blind to study assignment, conducted telephone interviews 3 and 6 months postbaseline. RESULTS: At 3 months, more intervention households reported a smoke-free home (46.6% vs 25.4%, p<0.0001; growth model intent-to-treat OR=1.48, 95% CI 1.241 to 1.772, p<0.0001). At 6 months, self-reported full bans were 62.9% for intervention participants and 38.4% for controls (OR=2.19). Texas trial participants were predominantly women (83%), single-smoker households (76%) and African-American (65%); half had incomes <=US$10 000/year (50%). Texas recruitment was <50% of the other sites. Fewer callers reported having a smoker in the household. Almost twice the callers with a household smoker declined interest in the programme/study. CONCLUSIONS: Our findings in a region with lower smoking rates and more diverse callers, including English-speaking Latinos, support programme generalisability and convey evidence of external validity. Our recruitment experience indicates that site-specific adjustments might improve recruitment efficiency and reach. TRIAL REGISTRATION NUMBER: NCT02097914, Results. PMID- 27697944 TI - Breathing clean air is Sa'ah Naaghai Bik'eh Hozhoo (SNBH): a culturally centred approach to understanding commercial smoke-free policy among the Dine (Navajo People). AB - INTRODUCTION: Indigenous worldviews and research approaches are fundamental to make meaning of complex health issues and increase the likelihood of identifying existing cultural protective factors that have contributed to the resilience and survival of Indigenous people worldwide. OBJECTIVE: We describe the process for applying the Dine (Navajo) paradigm of Sa'ah Naaghai Bik'eh Hozhoo (SNBH), a belief system that guides harmonious living, and demonstrate how the application of SNBH enhances understanding of Navajo principles for well-being. Specifically, we juxtapose this analysis with a conventional qualitative analysis to illuminate and interpret Dine perspectives on the health and economic impact of commercial secondhand smoke and smoke-free policy. METHODS: Focus groups were conducted throughout Navajo Nation to assess the appeal and impact of several evidence based messages regarding the health and economic impact of smoke-free policy. RESULTS: Dine perspectives have shifted away from family and cultural teachings considered protective of a smoke-free life, and struggle to balance the ethical and economics of respect for individual and collective rights to live and work in smoke-free environments. CONCLUSIONS: Indigenous-centred approaches to public health research and policy analysis contribute to understanding the cultural knowledge, practices and beliefs that are protective of the health and well-being of Indigenous people. PMID- 27697945 TI - Advancing smoke-free policy adoption on the Navajo Nation. AB - BACKGROUND: Comprehensive smoke-free laws are effective at protecting non-smokers and reducing tobacco use, yet they are not widely adopted by tribal governments. METHODS: A series of smoke-free policy initiatives on the Navajo Nation, beginning in 2008, were reviewed to identify key issues, successes and setbacks. RESULTS: It has been essential that proposed policies acknowledge the Navajo people's spiritual use of nat'oh, a sacred plant used for gift-giving, medicinal purposes and traditional ceremonies, while simultaneously discouraging a secular use of commercial tobacco. Concern that smoke-free policies economically harm tribal casinos has been a major barrier to broad implementation of comprehensive smoke-free laws in Navajo Nation. CONCLUSIONS: It is necessary for tobacco control researchers and advocates to build relationships with tribal leaders and casino management in order to develop the business case that will take comprehensive smoke-free policies to scale throughout tribal lands. PMID- 27697947 TI - Tobacco retail policy landscape: a longitudinal survey of US states. AB - BACKGROUND: There are ~380 000 tobacco retailers in the USA, where the largest tobacco companies spend almost $9 billion a year to promote their products. No systematic survey has been conducted of state-level activities to regulate the retail environment, thus little is known about what policies are being planned, proposed or implemented. METHODS: This longitudinal study is the first US survey of state tobacco control programmes (TCPs) about retail policy activities. Surveyed in 2012 and 2014, programme managers (n=46) reported activities in multiple domains: e-cigarettes, retailer density and licensing, non-tax price increases, product placement, advertising and promotion, health warnings and other approaches. Policy activities were reported in one of five levels: no formal activity, planning or advocating, policy was proposed, policy was enacted or policy was implemented. Overall and domain-specific activity scores were calculated for each state. RESULTS: The average retail policy activity almost doubled between 2012 and 2014. States with the largest increase in scores included: Minnesota, which established a fee-based tobacco retail licensing system and banned self-service for e-cigarettes and all other tobacco products (OTP); Oregon, Kansas and Maine, all of which banned self-service for OTP; and West Virginia, which banned some types of flavoured OTP. CONCLUSIONS: Retail policy activities in US states increased dramatically in a short time. Given what is known about the impact of the retail environment on tobacco use by youth and adults, state and local TCPs may want diversify policy priorities by implementing retail policies alongside tax and smoke-free air laws. PMID- 27697946 TI - Estimating cigarette tax avoidance and evasion: evidence from a national sample of littered packs. AB - INTRODUCTION: A number of recent studies document the proportion of all cigarette packs that are 'contraband' using discarded packs to measure tax avoidance and evasion, which we call tax non-compliance. To date, academic studies using discarded packs focused on relatively small geographical areas such as a city or a neighbourhood. METHODS: We visited 160 communities across 38 US states in 2012 and collected data from littered cigarette packs as part of the State and Community Tobacco Control (SCTC) Research Initiative and the Bridging the Gap Community Obesity Measures Project (BTG-COMP). Data collectors were trained in a previously tested littered pack data collection protocol. RESULTS: Field teams collected 2116 packs with cellophane across 132 communities. We estimate a national tax non-compliance rate of 18.5% with considerable variation across regions. Suburban areas had lower non-compliance than urban areas as well as areas with high and low median household income areas compared with middle income areas. DISCUSSION: We present the first academic national study of tax non compliance using littered cigarette packs. We demonstrate the feasibility of meaningful large-scale data collection using this methodology and document considerable variation in tax non-compliance across areas, suggesting that both policy differences and geography may be important in control of illicit tobacco use. Given the geography of open borders among countries with varying tax rates, this simple methodology may be appropriate to estimate tax non-compliance in countries that use tax stamps or other pack markings, such as health warnings. PMID- 27697948 TI - Do state minimum markup/price laws work? Evidence from retail scanner data and TUS-CPS. AB - BACKGROUND: Minimum markup/price laws (MPLs) have been proposed as an alternative non-tax pricing strategy to reduce tobacco use and access. However, the empirical evidence on the effectiveness of MPLs in increasing cigarette prices is very limited. This study aims to fill this critical gap by examining the association between MPLs and cigarette prices. METHODS: State MPLs were compiled from primary legal research databases and were linked to cigarette prices constructed from the Nielsen retail scanner data and the self-reported cigarette prices from the Tobacco Use Supplement to the Current Population Survey. Multivariate regression analyses were conducted to examine the association between MPLs and the major components of MPLs and cigarette prices. RESULTS: The presence of MPLs was associated with higher cigarette prices. In addition, cigarette prices were higher, above and beyond the higher prices resulting from MPLs, in states that prohibit below-cost combination sales; do not allow any distributing party to use trade discounts to reduce the base cost of cigarettes; prohibit distributing parties from meeting the price of a competitor, and prohibit distributing below cost coupons to the consumer. Moreover, states that had total markup rates >24% were associated with significantly higher cigarette prices. CONCLUSIONS: MPLs are an effective way to increase cigarette prices. The impact of MPLs can be further strengthened by imposing greater markup rates and by prohibiting coupon distribution, competitor price matching, and use of below-cost combination sales and trade discounts. PMID- 27697949 TI - Comparing projected impacts of cigarette floor price and excise tax policies on socioeconomic disparities in smoking. AB - BACKGROUND: About half of all US states have cigarette minimum price laws (MPLs) that require a per cent mark-up on prices, but research suggests they may not be very effective in raising prices. An alternative type of MPL sets a floor price below which packs cannot be sold, and may be more promising. This new type of MPL policy has only been implemented in 1 city, therefore its benefits relative to excise taxes is difficult to assess. METHODS: We constructed a set of possible state floor price MPL options, and matched them to possible state excise tax hikes designed to produce similar average price increases. Using self-reported price and cigarette consumption data from 23 521 participants in the 2010-2011 Tobacco Use Supplement of the Current Population Survey, we projected changes in pack prices and cigarette consumption following implementation of each paired MPL and tax option, for lower and higher income groups. RESULTS: We project that state MPLs set at the average reported pack price would raise prices by $0.33 and reduce cigarette consumption by about 4%; a tax with a similar average price effect would reduce consumption by 2.3%. MPLs and taxes that raise average prices by more than $2.00 would reduce consumption by 15.9% and 13.5%, respectively. In all models, we project that MPLs will reduce income-based smoking disparities more than their comparable excise taxes. CONCLUSIONS: Floor price cigarette MPLs set at or above what consumers currently report paying could reduce both tobacco use and socioeconomic disparities in smoking. PMID- 27697950 TI - Standardized Tobacco Assessment for Retail Settings (STARS): dissemination and implementation research. AB - OBJECTIVE: The Standardized Tobacco Assessment for Retail Settings (STARS) was designed to characterise the availability, placement, promotion and price of tobacco products, with items chosen for relevance to regulating the retail tobacco environment. This study describes the process to develop the STARS instrument and protocol employed by a collaboration of US government agencies, US state tobacco control programmes (TCPs), advocacy organisations, public health attorneys and researchers from the National Cancer Institute's State and Community Tobacco Control (SCTC) Research Initiative. METHODS: To evaluate dissemination and early implementation experiences, we conducted telephone surveys with state TCP leaders (n=50, response rate=100%), and with individuals recruited via a STARS download registry on the SCTC website. Website registrants were surveyed within 6 months of the STARS release (n=105, response rate=66%) and again after ~5 months (retention rate=62%). RESULTS: Among the state TCPs, 42 reported conducting any retail marketing surveillance, with actual or planned STARS use in 34 of these states and in 12 of the 17 states where marketing surveillance was not previously reported. Within 6 months of the STARS release, 21% of surveyed registrants reported using STARS and 35% were likely/very likely to use it in the next 6 months. To investigate implementation fidelity, we compared data collected by self-trained volunteers and by trained professionals, the latter method being more typically in retail marketing surveillance studies. Results suggest high or moderate reliability for most STARS measures. CONCLUSION: The study concludes with examples of states that used STARS to inform policy change. PMID- 27697951 TI - 'Sweeter Than a Swisher': amount and themes of little cigar and cigarillo content on Twitter. AB - OBJECTIVE: Despite recent increases in little cigar and cigarillo (LCC) use particularly among urban youth, African-Americans and Latinos-research on targeted strategies for marketing these products is sparse. Little is known about the amount or content of LCC messages users see or share on social media, a popular communication medium among youth and communities of colour. METHODS: Keyword rules were used to collect tweets related to LCCs from the Twitter Firehose posted in October 2014 and March-April 2015. Tweets were coded for promotional content, brand references, co-use with marijuana and subculture references (eg, rap/hip-hop, celebrity endorsements) and were classified as commercial and 'organic'/non-commercial using a combination of machine learning methods, keyword algorithms and human coding. Metadata associated with each tweet were used to categorise users as influencers (1000 and more followers) and regular users (under 1000 followers). RESULTS: Keyword filters captured over 4 372 293 LCC tweets. Analyses revealed that 17% of account users posting about LCCs were influencers and 1% of accounts were overtly commercial. Influencers were more likely to mention LCC brands and post promotional messages. Approximately 83% of LCC tweets contained references to marijuana and 29% of tweets were memes. Tweets also contained references to rap/hip-hop lyrics and urban subculture. CONCLUSIONS: Twitter is a major information-sharing and marketing platform for LCCs. Co-use of tobacco and marijuana is common and normalised on Twitter. The presence and broad reach of LCC messages on social media warrants urgent need for surveillance and serious attention from public health professionals and policymakers. Future tobacco use prevention initiatives should be adapted to ensure that they are inclusive of LCC use. PMID- 27697952 TI - Peer crowd affiliation as a segmentation tool for young adult tobacco use. AB - BACKGROUND: In California, young adult tobacco prevention is of prime importance; 63% of smokers start by the age of 18 years, and 97% start by the age of 26 years. We examined social affiliation with 'peer crowd' (eg, Hipsters) as an innovative way to identify high-risk tobacco users. METHODS: Cross-sectional surveys were conducted in 2014 (N=3368) among young adult bar patrons in 3 California cities. We examined use rates of five products (cigarettes, e cigarettes, hookah, cigars and smokeless tobacco) by five race/ethnicity categories. Peer crowd affiliation was scored based on respondents' selecting pictures of young adults representing those most and least likely to be in their friend group. Respondents were classified into categories based on the highest score; the peer crowd score was also examined as a continuous predictor. Logistic regression models with each tobacco product as the outcome tested the unique contribution of peer crowd affiliation, controlling for race/ethnicity, age, sex, sexual orientation and city. RESULTS: Respondents affiliating with Hip Hop and Hipster peer crowds reported significantly higher rates of tobacco use. As a categorical predictor, peer crowd was related to tobacco use, independent of associations with race/ethnicity. As a continuous predictor, Hip Hop peer crowd affiliation was also associated with tobacco use, and Young Professional affiliation was negatively associated, independent of demographic factors. CONCLUSIONS: Tobacco product use is not the same across racial/ethnic groups or peer crowds, and peer crowd predicts tobacco use independent of race/ethnicity. Antitobacco interventions targeting peer crowds may be an effective way to reach young adult tobacco users. TRIAL REGISTRATION NUMBER: NCT01686178, Pre-results. PMID- 27697953 TI - Long-term e-cigarette use and smoking cessation: a longitudinal study with US population. AB - BACKGROUND: E-cigarettes have grown popular. The most common pattern is dual use with conventional cigarettes. Dual use has raised concerns that it might delay quitting of cigarette smoking. This study examined the relationship between long term use of e-cigarettes and smoking cessation in a 2-year period. METHODS: A nationally representative sample of 2028 US smokers were surveyed in 2012 and 2014. Long-term e-cigarette use was defined as using e-cigarettes at baseline and follow-up. Use of e-cigarettes only at baseline or at follow-up was defined as short-term use. Non-users did not use e-cigarettes at either survey. Quit attempt rates and cessation rates (abstinent for 3 months or longer) were compared across the three groups. RESULTS: At 2-year follow-up, 43.7% of baseline dual users were still using e-cigarettes. Long-term e-cigarette users had a higher quit attempt rate than short-term or non-users (72.6% vs 53.8% and 45.5%, respectively), and a higher cessation rate (42.4% vs 14.2% and 15.6%, respectively). The difference in cessation rate between long-term users and non-users remained significant after adjusting for baseline variables, OR=4.1 (95% CI 1.5 to 11.4) as did the difference between long-term users and short-term users, OR=4.8 (95% CI 1.6 to 13.9). The difference in cessation rate between short-term users and non-users was not significant, OR=0.9 (95% CI 0.5 to 1.4). Among those making a quit attempt, use of e-cigarettes as a cessation aid surpassed that of FDA-approved pharmacotherapy. CONCLUSIONS: Short-term e-cigarette use was not associated with a lower rate of smoking cessation. Long-term use of e-cigarettes was associated with a higher rate of quitting smoking. PMID- 27697955 TI - Humor promotes learning! PMID- 27697954 TI - Traversing the triangulum: the intersection of tobacco, legalised marijuana and electronic vaporisers in Denver, Colorado. AB - OBJECTIVE: To explore the intersection of tobacco, legalised marijuana and electronic vaporiser use among young adults in the 'natural laboratory' of Colorado, the first state with legalised retail marijuana. METHODS: We conducted semistructured interviews with 32 young adults (18-26 years old) in Denver, Colorado, in 2015 to understand the beliefs and practices related to the use of tobacco, marijuana and vaporisers. RESULTS: We found ambiguity about whether the phrase 'to smoke' refers to the use of tobacco or marijuana products. Smoking marijuana blunts (emptied cigarillo or tobacco wrap filled with marijuana) was common, but few interpreted this as tobacco use. Marijuana vaporisers were used to circumvent public consumption laws (eg, while at work or when driving). Young adults considered secondhand tobacco smoke dangerous, but perceived secondhand marijuana smoke as benign. DISCUSSION: Using tobacco products as a delivery method for marijuana (eg, blunts) might be increasing and normalising tobacco use among young adults. Surveillance should explicitly ask about use of tobacco products for marijuana. Marijuana vaporisers, often indistinguishable from nicotine vaporisers, may be used to circumvent public consumption laws; communities concerned about use of marijuana in public spaces should include vaporisers (for nicotine or marijuana) in smoke-free regulations. Tobacco, marijuana and electronic vaporisers should be studied together, rather than separately. This approach is essential in informing research and policy as more US states and countries worldwide move to legalise marijuana. PMID- 27697956 TI - Team-based learning in large enrollment classes. AB - The goal of this review is to highlight the key elements needed to successfully deploy team-based learning (TBL) in any class, but especially in large enrolment classes, where smooth logistics are essential. The text is based on a lecture and workshop given at the American Physiological Society's Institute on Teaching and Learning in Madison, WI, in June 2016. After a short overview of the TBL method, its underpinning in learning theory, and a summary of current evidence for its effectiveness, we present two case studies from our own teaching practices in a new medical school. The first case study explores critical elements of design and planning for a TBL module, and the second explores best practices in classroom management. As medical educators in the fields of physiology, pediatrics, nephrology, and family medicine, we present the objective views of subject matter experts who adopted TBL as one teaching method rather than TBL experts or advocates per se. The review is aimed primarily at faculty contemplating using TBL for the first time who are interested in exploring the significant benefits and challenges of TBL. PMID- 27697957 TI - Systems biology: impressions from a newcomer graduate student in 2016. AB - As a newcomer, the philosophical basis of systems biology seems intuitive and appealing, the underlying philosophy being that the whole of a living system cannot be completely understood by the study of its individual parts. Yet answers to the questions "What is systems biology?" and "What constitutes a systems biology approach in 2016?" are somewhat more elusive. This seems to be due largely to the diversity of disciplines involved and the varying emphasis placed on the computational modeling and experimental aspects of systems biology. As such, the education of systems biology would benefit from multidisciplinary collaboration with both instructors and students from a range of disciplines within the same course. This essay is the personal reflection of a graduate student trying to get an introductory overview of the field of systems biology and some thoughts about effective education of systems biology. PMID- 27697958 TI - Faculty and second-year medical student perceptions of active learning in an integrated curriculum. AB - Patients expect physicians to be lifelong learners who are able to interpret and evaluate diagnostic tests, and most medical schools list the development of lifelong learning in their program objectives. However, lecture is the most often utilized form of teaching in the first two years and is considered passive learning. The current generation of medical students has many characteristics that should support active learning pedagogies. The purpose of this study was to analyze student and faculty perceptions of active learning in an integrated medical curriculum at the second-year mark, where students have been exposed to multiple educational pedagogies. The first hypothesis of the study was that faculty would favor active learning methods. The second hypothesis was that Millennial medical students would favor active learning due to their characteristics. Primary faculty for years 1 and 2 and second-year medical students were recruited for an e-mail survey consisting of 12 questions about active learning and lecture. Students perceived that lecture and passive pedagogies were more effective for learning, whereas faculty felt active and collaborative learning was more effective. Students believed that more content should be covered by lecture than faculty. There were also significant differences in perceptions of what makes a good teacher. Students and faculty both felt that lack of time in the curriculum and preparation time were barriers for faculty. The data suggest that students are not familiar with the process of learning and that more time may be needed to help students develop lifelong learning skills. PMID- 27697959 TI - Performance in physiology evaluation: possible improvement by active learning strategies. AB - The evaluation process is complex and extremely important in the teaching/learning process. Evaluations are constantly employed in the classroom to assist students in the learning process and to help teachers improve the teaching process. The use of active methodologies encourages students to participate in the learning process, encourages interaction with their peers, and stimulates thinking about physiological mechanisms. This study examined the performance of medical students on physiology over four semesters with and without active engagement methodologies. Four activities were used: a puzzle, a board game, a debate, and a video. The results show that engaging in activities with active methodologies before a physiology cognitive monitoring test significantly improved student performance compared with not performing the activities. We integrate the use of these methodologies with classic lectures, and this integration appears to improve the teaching/learning process in the discipline of physiology and improves the integration of physiology with cardiology and neurology. In addition, students enjoy the activities and perform better on their evaluations when they use them.

PMID- 27697966 TI - Technology-Facilitated Sexual Violence Victimization: Results From an Online Survey of Australian Adults. AB - Online forms of sexual harassment and abuse as experienced by adults represent an emerging yet under-researched set of behaviors, such that very few studies have sought to estimate the extent of the problem. This article presents the results of an online survey of 2,956 Australian adult (aged 18 to 54 years) experiences of technology-facilitated sexual violence (TFSV) victimization. The prevalence of TFSV was analyzed in relation to a 21-item scale developed in accordance with prior conceptual research identifying multiple dimensions of TFSV including digital sexual harassment, image-based sexual abuse, sexual aggression and/or coercion, and, gender and/or sexuality-based harassment (including virtual sexual violence). Results revealed significant differences in lifetime TFSV victimization for younger (18-24) and non-heterosexual identifying adults. Lifetime TFSV victimization for men and women was not significantly different, though women were more likely to report sexual harassment victimization and men were more likely to report victimization through the distribution of non consensual images, as well as gender and/or sexuality-based harassment. The authors conclude that although women and men report experiencing similar overall prevalence of TFSV victimization, the nature and impacts of those experiences differ in particular gendered ways that reflect broader patterns in both gender relations and "offline" sexual harassment.

PMID- 27697967 TI - Illness behaviour of general practitioners-a cross-sectional survey. AB - BACKGROUND: International guidelines recommend that physicians should be registered with a general practitioner (GP) and should avoid self-treatment. Adherence to these recommendations is mixed. AIMS: To describe illness behaviour and chronic medical conditions of GPs in Germany. METHODS: Cross-sectional, observational questionnaire study. We contacted 1000 GPs by mail in April 2014. We asked about registration with a GP, chronic conditions and self-treatment. We undertook descriptive statistical analysis and analysed associations using t tests and chi-square test. RESULTS: Two hundred and eighty-five responses (29%) were eligible for analysis. Nineteen per cent of GPs were registered as patients of a GP, 58% reported at least one chronic condition, 68% disclosed self diagnosis and 60% self-treatment. Self-therapy for chronic conditions was inversely correlated with subjective severity of the disease (r = -0.159; P < 0.05). CONCLUSIONS: The high rates of self-treatment and the low rate of registration with a GP of German GPs are in contrast to international guideline recommendations. Further research is needed to analyse specific reasons. PMID- 27697972 TI - Acute cardiovascular events and all-cause mortality in patients with hyperthyroidism: a population-based cohort study. AB - OBJECTIVE: Several studies have shown an increased risk for cardiovascular disease (CVD) in hyperthyroidism, but most studies have been too small to address the effect of hyperthyroidism on individual cardiovascular endpoints. Our main aim was to assess the association among hyperthyroidism, acute cardiovascular events and mortality. DESIGN: It is a nationwide population-based cohort study. Data were obtained from the Danish Civil Registration System and the Danish National Patient Registry, which covers all Danish hospitals. We compared the rate of all-cause mortality as well as venous thromboembolism (VTE), acute myocardial infarction (AMI), ischemic and non-ischemic stroke, arterial embolism, atrial fibrillation (AF) and percutaneous coronary intervention (PCI) in the two cohorts. Hazard ratios (HR) with 95% confidence intervals (95% CI) were estimated. RESULTS: The study included 85 856 hyperthyroid patients and 847 057 matched population-based controls. Mean follow-up time was 9.2 years. The HR for mortality was highest in the first 3 months after diagnosis of hyperthyroidism: 4.62, 95% CI: 4.40-4.85, and remained elevated during long-term follow-up (>3 years) (HR: 1.35, 95% CI: 1.33-1.37). The risk for all examined cardiovascular events was increased, with the highest risk in the first 3 months after hyperthyroidism diagnosis. The 3-month post-diagnosis risk was highest for atrial fibrillation (HR: 7.32, 95% CI: 6.58-8.14) and arterial embolism (HR: 6.08, 95% CI: 4.30-8.61), but the risks of VTE, AMI, ischemic and non-ischemic stroke and PCI were increased also 2- to 3-fold. CONCLUSIONS: We found an increased risk for all-cause mortality and acute cardiovascular events in patients with hyperthyroidism. PMID- 27697973 TI - Crossing the Line. PMID- 27697974 TI - A Change of Heart. PMID- 27697975 TI - Response to Targeted Therapy in BRAF Mutant Anaplastic Thyroid Cancer. AB - Anaplastic thyroid cancer (ATC) is an aggressive uncommon malignancy with limited treatment. Traditional antineoplastic chemotherapy has not been successful in the management of metastatic ATC. As a result, the focus has shifted to the development of novel therapies for this disease. The availability of economical comprehensive genomic profiling (CGP) platforms with rapid turn-around to identify molecular aberrations in tumors that are potential therapeutic targets has increasingly changed the face of cancer therapy. Identification of targetable aberrations may help identify novel treatment options for ATC. Herein, we report our experience with a 47-year-old patient with metastatic ATC who experienced recurrent, progressive disease and rapid clinical deterioration despite surgery, radiation therapy, and treatment with 2 different chemotherapy regimens. She was found to have a BRAF V600E mutation on CGP, and was started on targeted therapy with the BRAF inhibitor dabrafenib and the MEK inhibitor trametinib. After 2 months of treatment, she showed a clinical and radiologic response. The patient remained on this combination for 9 months until evidence of disease progression. Discontinuation of these drugs was associated with rapid tumor growth. Through this case we want to emphasize the importance of early molecular sequencing and identification of genetic aberrations in patients with ATC, and using that information to develop therapies for ATC, an aggressive malignancy with limited therapy and a poor outcome. PMID- 27697977 TI - Emerging Issues and Opportunities in Health Information Technology. AB - When used effectively, health information technology (HIT) can transform clinical care and contribute to new research discoveries. Despite advances in HIT and increased electronic health record adoption, many challenges to optimal use, interoperability, and data sharing exist. Data standardization across systems is limited, and scanned medical note documents result in unstructured data that make reporting on quality measures for reimbursement burdensome. Different policies and initiatives, including the Health Information Technology for Economic and Clinical Health Act, the Medicare Access and CHIP Reauthorization Act, and the National Cancer Moonshot initiative, among others, all recognize the impact that HIT can have on cancer care. Given the growing role HIT plays in health care, it is vital to have effective and efficient HIT systems that can exchange information, collect credible data that is analyzable at the point of care, and improves the patient-provider relationship. In June 2016, NCCN hosted the Emerging Issues and Opportunities in Health Information Technology Policy Summit. The summit addressed challenges, issues, and opportunities in HIT as they relate to cancer care. Keynote presentations and panelists discussed moving beyond Meaningful Use, HIT readiness to support and report on quality care, the role of HIT in precision medicine, the role of HIT in the National Cancer Moonshot initiative, and leveraging HIT to improve quality of clinical care. PMID- 27697978 TI - Practice Patterns in the Diagnosis and Treatment of Polycythemia Vera in the Post JAK2 V617F Discovery Era. AB - Polycythemia vera (PV) is an acquired clonal hematopoietic stem cell disorder characterized by an overproduction of red blood cells, white blood cells, and platelets; thrombotic and hemorrhagic complications; and an increased risk of transformation to myelofibrosis and acute leukemia. In 1967, the Polycythemia Vera Study Group proposed the optimal approach to diagnosis and treatment of PV, and in 2002, investigators from Johns Hopkins University School of Medicine surveyed the practice patterns of hematologists as they pertained to PV. Since this survey, the JAK2 V617F mutation was discovered, leading to a new era of discovery in the disease pathogenesis, diagnosis, and classification and treatment of PV. Our objective was to survey hematologists in the diagnosis and treatment of PV in the modern, post-JAK2 V617F discovery era. An anonymous 17 question survey was emailed to members of the Myeloproliferative Neoplasm (MPN) Research Foundation database and Aplastic Anemia and MDS International Foundation. A total of 71 surveys were used in the analysis. Diagnostic testing varied according to the respondent's clinical experience and practice type. In addition, there were marked differences in target hematocrit and platelet count among those surveyed. There continue to be variations in diagnosis and treatment of PV despite WHO guidelines and the JAK2 discovery. US-based guidelines for MPNs are needed to create consistency in the management of PV and other MPNs. PMID- 27697976 TI - NCCN Guidelines Insights: Bladder Cancer, Version 2.2016. AB - These NCCN Guidelines Insights discuss the major recent updates to the NCCN Guidelines for Bladder Cancer based on the review of the evidence in conjunction with the expert opinion of the panel. Recent updates include (1) refining the recommendation of intravesical bacillus Calmette-Guerin, (2) strengthening the recommendations for perioperative systemic chemotherapy, and (3) incorporating immunotherapy into second-line therapy for locally advanced or metastatic disease. These NCCN Guidelines Insights further discuss factors that affect integration of these recommendations into clinical practice. PMID- 27697979 TI - Merkel Cell Carcinoma: A Population Analysis on Survival. AB - PURPOSE: Merkel cell carcinoma (MCC) is an aggressive cutaneous malignancy. However, factors associated with disease presentation and outcomes remain uncertain, especially in light of recent changes in workup, such as sentinel lymph node biopsy. Therefore, this study used the SEER database to examine factors that could affect stage at presentation and treatment. METHODS: We identified 4,543 patients and evaluated associations between sex, race, age, primary disease site, disease presentation, and treatment. We also used univariate and multivariate analyses to examine the effect of these factors on disease-specific survival (DSS) and overall survival (OS). We specifically conducted subgroup analyses on a more modern cohort of patients with MCC treated between 2006 and 2012. RESULTS: Male sex, older age, larger tumor size, and primary tumors of the scalp, neck, or trunk were associated with a higher burden of nodal disease. Multivariate predictors of worse DSS/OS in both the recent and overall cohort included age older than 75 years, number of lymph nodes involved, tumors greater than 5 cm, metastatic disease, or lack of radiation therapy. The number of involved nodes was the best predictor of DSS/OS. Associations with radiation therapy were most pronounced in patients with nodal disease and those not undergoing surgery. CONCLUSIONS: Sex, age, tumor size, and primary site of disease correlated with burden of nodal disease in MCC. Associations between disease presentation and treatment strategies such as radiation and DSS and OS have remained relatively constant in the modern era from 2006 to 2012 compared with findings from prior studies. PMID- 27697980 TI - Effects of a Provincial-Wide Implementation of Screening for Distress on Healthcare Professionals' Confidence and Understanding of Person-Centered Care in Oncology. AB - BACKGROUND: Although published studies report that screening for distress (SFD) improves the quality of care for patients with cancer, little is known about how SFD impacts healthcare professionals (HCPs). OBJECTIVES: This quality improvement project examined the impact of implementing the SFD intervention on HCPs' confidence in addressing patient distress and awareness of person-centered care. PATIENTS AND METHODS: This project involved pre-evaluation and post-evaluation of the impact of implementing SFD. A total of 254 HCPs (cohort 1) were recruited from 17 facilities across the province to complete questionnaires. SFD was then implemented at all cancer care facilities over a 10-month implementation period, after which 157 HCPs (cohort 2) completed post-implementation questionnaires. At regional and community care centers, navigators supported the integration of SFD into routine practice; therefore, the impact of navigators was examined. RESULTS: HCPs in cohort 2 reported significantly greater confidence in managing patients' distress and greater awareness about person-centered care relative to HCPs in cohort 1. HCPs at regional and community sites reported greater awareness in person-centeredness before and after the intervention, and reported fewer negative impacts of SFD relative to HCPs at tertiary sites. Caring for single or multiple tumor types was an effect modifier, with effects observed only in the HCPs treating multiple tumors. CONCLUSIONS: Implementation of SFD was beneficial for HCPs' confidence and awareness of person-centeredness. Factors comprising different models of care, such as having site-based navigators and caring for single or multiple tumors, influenced outcomes. PMID- 27697981 TI - High Body Mass Index in Elderly Patients With DLBCL Treated With Rituximab Containing Therapy Compensates for Negative Impact of Male Sex. AB - BACKGROUND: The impact of patient body habitus and sex on outcomes in diffuse large B-cell lymphoma (DLBCL) remains controversial. We investigated the impact of body mass index (BMI), body surface area (BSA), age, and sex on clinical outcomes in patients with DLBCL treated in the rituximab era. PATIENTS AND METHODS: Patients with de novo DLBCL (n=1,386) diagnosed between June 2000 and December 2010 treated with rituximab-containing chemotherapy were identified from the NCCN Oncology Outcomes Database for Non-Hodgkin's Lymphoma. Progression-free survival (PFS) and overall survival (OS) at 3 years were analyzed based on sex, age, and baseline BMI/BSA. RESULTS: High BMI was associated with a lower risk of disease progression or death than low or normal BMI, whereas male sex was associated with poor clinical outcomes, especially among elderly patients (age >60 years). Compared with elderly women, elderly men experienced worse PFS (3 year hazard ratio [HR], 1.5) and OS (3-year HR, 1.6), but these differences diminished with increases in BMI and BSA. In multivariable analysis, normal BMI compared with high BMI was independently associated with poor outcomes (3-year PFS HR, 1.5; OS HR, 1.6) after adjusting for sex. Notably, only 13% of elderly men had BMI less than 25 kg/m2 and only 26% had BSA less than 2 m2 CONCLUSIONS: Analysis of unselected patients with DLBCL treated with rituximab-containing chemotherapy confirmed an age-dependent disadvantage to male sex in treatment outcomes, but this effect is abrogated by higher levels of BMI and BSA in most North American men. PMID- 27697982 TI - Gastric Cancer, Version 3.2016, NCCN Clinical Practice Guidelines in Oncology. AB - Gastric cancer is the fifth most frequently diagnosed cancer and the third leading cause of death from cancer in the world. Several advances have been made in the staging procedures, imaging techniques, and treatment approaches. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Gastric Cancer provide an evidence- and consensus-based treatment approach for the management of patients with gastric cancer. This manuscript discusses the recommendations outlined in the NCCN Guidelines for staging, assessment of HER2 overexpression, systemic therapy for locally advanced or metastatic disease, and best supportive care for the prevention and management of symptoms due to advanced disease. PMID- 27697983 TI - Advances in Systemic Therapy for Metastatic or Advanced Gastric Cancer. AB - In recent years, various new agents have been investigated for the treatment of advanced gastric cancer (AGC). The anti-HER2 antibody trastuzumab has been shown to prolong the overall survival of patients with HER2-positive AGC and has become a standard treatment. However, lapatinib, or ado-trastuzumab emtansine (T-DM1), did not show survival benefit in AGC, although it has shown remarkable efficacy for HER2-positive breast cancer. The efficacy of the anti-vascular endothelial growth factor receptor monoclonal antibody ramucirumab for pretreated gastric cancer is a milestone for antiangiogenic therapy for AGC. Early clinical trials of TAS-118, TAS-102, and STAT3 inhibitors; IMAB362 (anti-Claudin 18.2); and immune checkpoint inhibitors are all encouraging. These findings warrant further evaluation in larger clinical trials. PMID- 27697984 TI - Multimodality Therapy of Localized Gastric Adenocarcinoma. AB - Surgical resection is the primary method of obtaining a potential cure for patients with gastric adenocarcinoma. However, chemotherapy or chemoradiotherapy offer significant improvement in survival over surgery alone. Much of the difficulty in deciding the optimal treatment strategy is choosing between perioperative chemotherapy or adjuvant chemoradiotherapy. Adding to the complexity is the potential for incorporating treatment strategies based on clinical trials performed in Asia. There is likely a difference in tumor biology between Eastern and Western patients with gastric adenocarcinoma, in addition to the clear differences in screening, pathologic assessment, and surgical technique. Even among tumors in Western populations, heterogeneity of histology, anatomy, and staging among studies make cross-trial comparisons difficult. There is also active controversy surrounding the staging and management of gastroesophageal junction tumors. Lastly, the benefit of extended lymph node dissection is not clear based on the existing studies and has not been firmly established as a surgical standard of care for all patients. Future goals include better classification of gastric cancer, continued pursuit of randomized trials in Western populations, standardization of surgical technique, and incorporation of targeted therapies.

PMID- 27697987 TI - Neural correlates of three types of negative life events during angry face processing in adolescents. AB - Negative life events (NLE) contribute to anxiety and depression disorders, but their relationship with brain functioning in adolescence has rarely been studied. We hypothesized that neural response to social threat would relate to NLE in the frontal-limbic emotional regions. Participants (N = 685) were drawn from the Imagen database of 14-year-old community adolescents recruited in schools. They underwent functional MRI while viewing angry and neutral faces, as a probe to neural response to social threat. Lifetime NLEs were assessed using the 'distress', 'family' and 'accident' subscales from a life event dimensional questionnaire. Relationships between NLE subscale scores and neural response were investigated. Links of NLE subscales scores with anxiety or depression outcomes at the age of 16 years were also investigated. Lifetime 'distress' positively correlated with ventral-lateral orbitofrontal and temporal cortex activations during angry face processing. 'Distress' scores correlated with the probabilities of meeting criteria for Generalized Anxiety Disorder or Major Depressive Disorder at the age of 16 years. Lifetime 'family' and 'accident' scores did not relate with neural response or follow-up conditions, however. Thus, different types of NLEs differentially predicted neural responses to threat during adolescence, and differentially predicted a de novo internalizing condition 2 years later. The deleterious effect of self-referential NLEs is suggested. PMID- 27697992 TI - FCGR, Cetuximab, and Colorectal Cancer Survival-Letter. PMID- 27697991 TI - Dual Characteristics of Novel HER2 Kinase Domain Mutations in Response to HER2 Targeted Therapies in Human Breast Cancer. AB - PURPOSE: Somatic mutations in the tyrosine kinase domain of human epidermal growth factor receptor 2 (HER2) may be an alternative mechanism to HER2 activation and can affect the sensitivity toward HER2-targeted therapies. We aimed to investigate the prevalence, clinicopathologic characteristics, and functional relevance of novel HER2 mutations in breast cancer. EXPERIMENTAL DESIGN: We performed Sanger sequencing of all exons of the HER2 gene in 1,248 primary tumors and 18 paired metastatic samples. Novel HER2 mutations were functionally characterized. RESULTS: The total HER2 somatic mutation rate was 2.24% (28/1,248). Of the seven novel HER2 mutations, L768S and V773L were only detected in HER2-negative tumors, whereas K753E was found in HER2-positive disease. L768S and V773L mutations exhibited a significant increase in tyrosine kinase-specific activity and strongly increased the phosphorylation of signaling proteins in various cell lines. Xenograft experiments showed that NIH3T3 cells bearing the L768S and V773L mutations displayed more rapid growth. MCF10A, BT474, and MDA-MB-231 cells bearing the K753E mutation were resistant to lapatinib, but could be inhibited by neratinib. Finally, comparison of HER2 mutations in 18 pairs of primary and metastatic lesions revealed that the drug-resistant HER2 mutations (K753E and L755S) were enriched in metastatic lesions. CONCLUSIONS: HER2-negative breast cancer with activating mutations can benefit from HER2 targeted therapies. Meanwhile, mutations in the HER2 kinase domain might be a key mechanism of resistance to HER2-targeted therapy, and irreversible tyrosine kinase inhibitors such as neratinib may offer alternative treatment options.

PMID- 27697994 TI - The Dual Syk/JAK Inhibitor Cerdulatinib Antagonizes B-cell Receptor and Microenvironmental Signaling in Chronic Lymphocytic Leukemia. AB - Purpose: B-cell receptor (BCR)-associated kinase inhibitors, such as ibrutinib, have revolutionized the treatment of chronic lymphocytic leukemia (CLL). However, these agents are not curative, and resistance is already emerging in a proportion of patients. IL4, expressed in CLL lymph nodes, can augment BCR signaling and reduce the effectiveness of BCR kinase inhibitors. Therefore, simultaneous targeting of the IL4- and BCR signaling pathways by cerdulatinib, a novel dual Syk/JAK inhibitor currently in clinical trials (NCT01994382), may improve treatment responses in patients.Experimental Design: PBMCs from patients with CLL were treated in vitro with cerdulatinib alone or in combination with venetoclax. Cell death, chemokine, and cell signaling assay were performed and analyzed by flow cytometry, immunoblotting, q-PCR, and ELISA as indicated.Results: At concentrations achievable in patients, cerdulatinib inhibited BCR- and IL4 induced downstream signaling in CLL cells using multiple readouts and prevented anti-IgM- and nurse-like cell (NLC)-mediated CCL3/CCL4 production. Cerdulatinib induced apoptosis of CLL cells, in a time- and concentration-dependent manner, and particularly in IGHV-unmutated samples with greater BCR signaling capacity and response to IL4, or samples expressing higher levels of sIgM, CD49d+, or ZAP70+ Cerdulatinib overcame anti-IgM, IL4/CD40L, or NLC-mediated protection by preventing upregulation of MCL-1 and BCL-XL; however, BCL-2 expression was unaffected. Furthermore, in samples treated with IL4/CD40L, cerdulatinib synergized with venetoclax in vitro to induce greater apoptosis than either drug alone.Conclusions: Cerdulatinib is a promising therapeutic for the treatment of CLL either alone or in combination with venetoclax, with the potential to target critical survival pathways in this currently incurable disease.

AB - Purpose: Gut microbiota have been implicated in the development of colorectal cancer. We evaluated the utility of fecal bacterial marker candidates identified by our metagenome sequencing analysis for colorectal cancer diagnosis.Experimental Design: Subjects (total 439; 203 colorectal cancer and 236 healthy subjects) from two independent Asian cohorts were included. Probe-based duplex quantitative PCR (qPCR) assays were established for the quantification of bacterial marker candidates.Results: Candidates identified by metagenome sequencing, including Fusobacterium nucleatum (Fn), Bacteroides clarus (Bc), Roseburia intestinalis (Ri), Clostridium hathewayi (Ch), and one undefined species (labeled as m7), were examined in fecal samples of 203 colorectal cancer patients and 236 healthy controls by duplex-qPCR. Strong positive correlations were demonstrated between the quantification of each candidate by our qPCR assays and metagenomics approach (r = 0.801-0.934, all P < 0.0001). Fn was significantly more abundant in colorectal cancer than controls (P < 0.0001), with AUROC of 0.868 (P < 0.0001). At the best cut-off value maximizing sum of sensitivity and specificity, Fn discriminated colorectal cancer from controls with a sensitivity of 77.7%, and specificity of 79.5% in cohort I. A simple linear combination of four bacteria (Fn + Ch + m7-Bc) showed an improved diagnostic ability compared with Fn alone (AUROC = 0.886, P < 0.0001) in cohort I. These findings were further confirmed in an independent cohort II. In particular, improved diagnostic performances of Fn alone (sensitivity 92.8%, specificity 79.8%) and four bacteria (sensitivity 92.8%, specificity 81.5%) were achieved in combination with fecal immunochemical testing for the detection of colorectal cancer.Conclusions: Stool based colorectal cancer-associated bacteria can serve as novel noninvasive diagnostic biomarkers for colorectal cancer.

AB - Purpose: There is an important need to improve the effectiveness of radio chemotherapy (RTCT) for cervical cancer. The CXCL12/CXCR4 pathway can influence RT response by recruiting normal myeloid cells to the tumor microenvironment that in turn can exert radioprotective effects, and may promote metastases. The objective of this study was to explore the efficacy and toxicity of combining RTCT with CXCL12/CXCR4 inhibition in cervical cancer.Experimental Design: CXCR4 expression was measured in 115 patients with cervical cancer. Two primary orthotopic cervical cancer xenografts (OCICx) with different levels of CXCR4 expression were treated with RT (30 Gy: 15 daily fractions) and weekly cisplatin (4 mg/kg), with or without the CXCR4 inhibitor Plerixafor (5 mg/kg/day). The endpoints were tumor growth delay and lymph node metastases. Acute intestinal toxicity was assessed using a crypt cell assay.Results: There was a fivefold variation in CXCR4 mRNA expression in the patient samples, and good correlation between the expression in patients and in the xenografts. The combination of RTCT and Plerixafor produced substantial tumor growth delay and reduced lymph node metastases compared with RTCT alone in both of the xenograft models. There was a trend toward reduced acute intestinal toxicity with the addition of Plerixafor to RTCT. There were no changes in normal organ morphology to suggest increased late toxicity.Conclusions: This study demonstrates that the addition of Plerixafor to standard RTCT improves primary tumor response and reduces metastases in cervical cancer with no increase in toxicity. This combination warrants further investigation in phase I/II clinical trials. Clin Cancer Res; 23(5); 1242-9. (c)2016 AACR. PMID- 27697998 TI - Targeting Hypoxic Prostate Tumors Using the Novel Hypoxia-Activated Prodrug OCT1002 Inhibits Expression of Genes Associated with Malignant Progression. AB - Purpose: To understand the role of hypoxia in prostate tumor progression and to evaluate the ability of the novel unidirectional hypoxia-activated prodrug OCT1002 to enhance the antitumor effect of bicalutamide.Experimental Design: The effect of OCT1002 on prostate cancer cells (LNCaP, 22Rv1, and PC3) was measured in normoxia and hypoxia in vitroIn vivo, tumor growth and lung metastases were measured in mice treated with bicalutamide, OCT1002, or a combination. Dorsal skin fold chambers were used to image tumor vasculature in vivo Longitudinal gene expression changes in tumors were analyzed using PCR.Results: Reduction of OCT1002 to its active form (OCT1001) decreased prostate cancer cell viability. In LNCaP-luc spheroids, OCT1002 caused increased apoptosis and decreased clonogenicity. In vivo, treatment with OCT1002 alone, or with bicalutamide, showed significantly greater tumor growth control and reduced lung metastases compared with controls. Reestablishment of the tumor microvasculature following bicalutamide-induced vascular collapse is inhibited by OCT1002. Significantly, the upregulation of RUNX2 and its targets caused by bicalutamide alone was blocked by OCT1002.Conclusions: OCT1002 selectively targets hypoxic tumor cells and enhances the antitumor efficacy of bicalutamide. Furthermore, bicalutamide caused changes in gene expression, which indicated progression to a more malignant genotype; OCT1002 blocked these effects, emphasizing that more attention should be attached to understanding genetic changes that may occur during treatment. Early targeting of hypoxic cells with OCT1002 can provide a means of inhibiting prostate tumor growth and malignant progression. This is of importance for the design and refinement of existing androgen-deprivation regimens in the clinic. Clin Cancer Res; 23(7); 1797-808. (c)2016 AACR. PMID- 27697999 TI - The Sphingosine-1-Phosphate Modulator FTY720 Targets Multiple Myeloma via the CXCR4/CXCL12 Pathway. AB - Purpose: To explore the functional consequences of possible cross-talk between the CXCR4/CXCL12 and the sphingosine-1-phosphate (S1P) pathways in multiple myeloma (MM) cells and to evaluate the effect of S1P targeting with the FTY720 modulator as a potential anti-MM therapeutic strategy.Experimental Design and Results: S1P targeting with FTY720 induces MM cell apoptosis. The combination of FTY720 with the SPHK1 inhibitor SKI-II results in synergistic inhibition of MM growth. CXCR4/CXCL12-enhanced expression correlates with reduced MM cell sensitivity to both FTY720 and SKI-II inhibitors, and with SPHK1 coexpression in both cell lines and primary MM bone marrow (BM) samples, suggesting regulative cross-talk between the CXCR4/CXCL12 and SPHK1 pathways in MM cells. FTY720 was found to directly target CXCR4. FTY720 profoundly reduces CXCR4 cell-surface levels and abrogates the CXCR4-mediated functions of migration toward CXCL12 and signaling pathway activation. Moreover, FTY720 cooperates with bortezomib, inducing its cytotoxic activity and abrogating the bortezomib-mediated increase in CXCR4 expression. FTY720 effectively targets bortezomib-resistant cells and increases their sensitivity to bortezomib, promoting DNA damage. Finally, in a recently developed novel xenograft model of CXCR4-dependent systemic MM with BM involvement, FTY720 treatment effectively reduces tumor burden in the BM of MM bearing mice. FTY720 in combination with bortezomib demonstrates superior tumor growth inhibition and abrogates bortezomib-induced CXCR4 increase on MM cells.Conclusions: Altogether, our work identifies a cross-talk between the S1P and CXCR4 pathways in MM cells and provides a preclinical rationale for the therapeutic application of FTY720 in combination with bortezomib in patients with MM.

AB - Purpose: Fluorine-18 fluorodeoxyglucose positron emission tomography with CT attenuation correction (18F-FDG PET/CT) is useful in the detection and enumeration of focal lesions and in semiquantitative characterization of metabolic activity (glycolytic phenotype) by calculation of glucose uptake. Total lesion glycolysis (TLG) and metabolic tumor volume (MTV) have the potential to improve the value of this approach and enhance the prognostic value of disease burden measures. This study aims to determine whether TLG and MTV are associated with progression-free survival (PFS) and overall survival (OS), and whether they improve risk assessments such as International Staging System (ISS) stage and GEP70 risk.Experimental Design: 192 patients underwent whole body PET/CT in the Total Therapy 3A (TT3A) trial and were evaluated using three-dimensional region of-interest analysis with TLG, MTV, and standard measurement parameters derived for all focal lesions with peak SUV above the background red marrow signal.Results: In multivariate analysis, baseline TLG > 620 g and MTV > 210 cm3 remained a significant factor of poor PFS and OS after adjusting for baseline myeloma variables. Combined with the GEP70 risk score, TLG > 205 g identifies a high-risk-behaving subgroup with poor expected survival. In addition, TLG > 205 g accurately divides ISS stage II patients into two subgroups with similar outcomes to ISS stage I and ISS stage III, respectively.Conclusions: TLG and MTV have significant survival implications at baseline and offer a more precise quantitation of the glycolytic phenotype of active disease. These measures can be assessed more readily than before using FDA-approved software and should be standardized and incorporated into clinical trials moving forward. Clin Cancer Res; 23(8); 1981-7.

AB - Immunotherapy has led to a paradigm shift in the treatment of some malignancies, providing long-term, durable responses for patients with advanced cancers. However, such therapy has benefited only a subset of patients, with some patients failing to respond to treatment at all and others achieving a limited response followed by tumor progression. Understanding factors contributing to an effective response and further elucidating mechanisms of resistance will be crucial as these therapies are applied more broadly. Genomics-based approaches have significantly advanced the study of response and resistance to immunotherapy in general, and to immune checkpoint blockade more specifically. Here, we review how genomic and transcriptomic approaches have identified both somatic and germline positive correlates of response, including high mutational/neoantigen load and low intratumoral heterogeneity, among others. The genomic analysis of resistant tumors has additionally identified crucial factors involved in resistance to immune checkpoint blockade, including loss of PTEN and upregulation of other immune checkpoints. Overall, the continued use of genomic techniques at the point of care, combined with appropriate functional studies, would ideally lead to a better understanding of why certain patients respond to immune-based therapies, allowing clinicians to identify the subset of patients likely to benefit from such therapy, and potentially providing insight into how other therapies may be added in combination to increase the number of patients who may benefit from immunotherapy.

AB - PURPOSE: Although trastuzumab administration improved the outcome of HER2 positive breast cancer patients, resistance events hamper its clinical benefits. We demonstrated that TNFalpha stimulation in vitro induces trastuzumab resistance in HER2-positive breast cancer cell lines. Here, we explored the mechanism of TNFalpha-induced trastuzumab resistance and the therapeutic strategies to overcome it. EXPERIMENTAL DESIGN: Trastuzumab-sensitive breast cancer cells, genetically engineered to stably overexpress TNFalpha, and de novo trastuzumab resistant tumors, were used to evaluate trastuzumab response and TNFalpha blocking antibodies effectiveness respectively. Immunohistochemistry and antibody dependent cell cytotoxicity (ADCC), together with siRNA strategy, were used to explore TNFalpha influence on the expression and function of its downstream target, mucin 4 (MUC4). The clinical relevance of MUC4 expression was studied in a cohort of 78 HER2-positive breast cancer patients treated with adjuvant trastuzumab. RESULTS: TNFalpha overexpression turned trastuzumab-sensitive cells and tumors into resistant ones. Histopathologic findings revealed mucin foci in TNFalpha-producing tumors. TNFalpha induced upregulation of MUC4 that reduced trastuzumab binding to its epitope and impaired ADCC. Silencing MUC4 enhanced trastuzumab binding, increased ADCC, and overcame trastuzumab and trastuzumab emtansine antiproliferative effects in TNFalpha-overexpressing cells. Accordingly, administration of TNFalpha-blocking antibodies downregulated MUC4 and sensitized de novo trastuzumab-resistant breast cancer cells and tumors to trastuzumab. In HER2-positive breast cancer samples, MUC4 expression was found to be an independent predictor of poor disease-free survival (P = 0.008). CONCLUSIONS: We identified TNFalpha-induced MUC4 expression as a novel trastuzumab resistance mechanism. We propose MUC4 expression as a predictive biomarker of trastuzumab efficacy and a guide to combination therapy of TNFalpha blocking antibodies with trastuzumab. Clin Cancer Res; 23(3); 636-48.

PMID- 27698003 TI - Estimation of Survival Probabilities for Use in Cost-effectiveness Analyses: A Comparison of a Multi-state Modeling Survival Analysis Approach with Partitioned Survival and Markov Decision-Analytic Modeling. AB - Modeling of clinical-effectiveness in a cost-effectiveness analysis typically involves some form of partitioned survival or Markov decision-analytic modeling. The health states progression-free, progression and death and the transitions between them are frequently of interest. With partitioned survival, progression is not modeled directly as a state; instead, time in that state is derived from the difference in area between the overall survival and the progression-free survival curves. With Markov decision-analytic modeling, a priori assumptions are often made with regard to the transitions rather than using the individual patient data directly to model them. This article compares a multi-state modeling survival regression approach to these two common methods. As a case study, we use a trial comparing rituximab in combination with fludarabine and cyclophosphamide v. fludarabine and cyclophosphamide alone for the first-line treatment of chronic lymphocytic leukemia. We calculated mean Life Years and QALYs that involved extrapolation of survival outcomes in the trial. We adapted an existing multi state modeling approach to incorporate parametric distributions for transition hazards, to allow extrapolation. The comparison showed that, due to the different assumptions used in the different approaches, a discrepancy in results was evident. The partitioned survival and Markov decision-analytic modeling deemed the treatment cost-effective with ICERs of just over L16,000 and L13,000, respectively. However, the results with the multi-state modeling were less conclusive, with an ICER of just over L29,000. This work has illustrated that it is imperative to check whether assumptions are realistic, as different model choices can influence clinical and cost-effectiveness results. PMID- 27698004 TI - Effects of Nurses' Perceptions of Actual and Demanded Competence on Turnover Intentions. AB - With the growing focus on continuous professional development, demands placed on nurses to uphold nursing competence have been increasing. This study examined how nurses with different lengths of clinical experience perceived the relationship between their actual competence and the competence they felt was demanded of them, and how this relationship was related to their turnover intentions. Survey questionnaires were distributed to 1,377 nurses, of whom 765 returned usable completed forms. The results showed that across all the groups of clinical experience, nurses perceived the demanded competence levels to be higher than their actual competence levels. However, turnover intentions were not related to nurses' perceptions of demanded competence and were negatively related to perceptions of actual competence. The levels of competence demanded should not be considered as threats for nurses. Improving nurses' competence may reduce their turnover intentions. PMID- 27698006 TI - The Authors Reply.

PMID- 27698008 TI - Phlebitis as a consequence of peripheral intravenous administration of cisatracurium besylate in critically ill patients. AB - This case report series describes 3 cases of cisatracurium besylate associated phlebitis after an infusion period of 14-20 hours. No similar cases have been reported in the literature. Association of phlebitis with another neuromuscular blocking agent, atracurium, has been described in the literature. The acidity of atracurium is thought to be the main cause. It is recommended that atracurium is administered only via central venous catheters when indicated to infuse over prolonged periods of time due to the acidity. Cisatracurium is a stereoisomer of atracurium and as such has the same molecular weight. Although cisatracurium also has a similar acidity as atracurium, a recommendation concerning infusion via a central venous catheter is lacking. We suggest prolonged administration of cisatracurium besylate only via centrally placed venous catheters or if not possible to careful monitor relevant peripheral intravenous sites to diminish the risks of phlebitis and associated complications or other cutaneous reactions. PMID- 27698005 TI - Risk Prediction for Epithelial Ovarian Cancer in 11 United States-Based Case Control Studies: Incorporation of Epidemiologic Risk Factors and 17 Confirmed Genetic Loci. AB - Previously developed models for predicting absolute risk of invasive epithelial ovarian cancer have included a limited number of risk factors and have had low discriminatory power (area under the receiver operating characteristic curve (AUC) < 0.60). Because of this, we developed and internally validated a relative risk prediction model that incorporates 17 established epidemiologic risk factors and 17 genome-wide significant single nucleotide polymorphisms (SNPs) using data from 11 case-control studies in the United States (5,793 cases; 9,512 controls) from the Ovarian Cancer Association Consortium (data accrued from 1992 to 2010). We developed a hierarchical logistic regression model for predicting case-control status that included imputation of missing data. We randomly divided the data into an 80% training sample and used the remaining 20% for model evaluation. The AUC for the full model was 0.664. A reduced model without SNPs performed similarly (AUC = 0.649). Both models performed better than a baseline model that included age and study site only (AUC = 0.563). The best predictive power was obtained in the full model among women younger than 50 years of age (AUC = 0.714); however, the addition of SNPs increased the AUC the most for women older than 50 years of age (AUC = 0.638 vs. 0.616). Adapting this improved model to estimate absolute risk and evaluating it in prospective data sets is warranted. PMID- 27698009 TI - Acute eosinophilic pneumonia masquerading as multiple pulmonary embolisms. AB - A 47-year-old previously healthy man was admitted to the hospital with a 5-day history of fever, dry cough, and dyspnoea. Thoracic radiographs and CT scan showed extensive bilateral consolidation predominantly involving the central portions of the upper lung lobes, along with multiple scattered nodules. On taking a thorough history, it was found that the patient had visited a gritty 100 year-old Japanese folk house 1 week ago. An urgent bronchoscopy was performed, and the results were consistent with the findings of acute eosinophilic pneumonia (AEP). The patient's respiratory distress resolved within 10 days without treatment. Hence, even in an AEP case with atypical radiological presentations, careful history taking can lead to a rapid diagnosis. PMID- 27698010 TI - Circulating Soluble IL-6R but Not ADAM17 Activation Drives Mononuclear Cell Migration in Tissue Inflammation. AB - Neutrophil and mononuclear cell infiltration during inflammatory processes is highly regulated. The first cells at the site of infection or inflammation are neutrophils, followed by mononuclear cells. IL-6 plays an important role during inflammatory states. It has been shown in several models that the soluble form of IL-6R (sIL-6R) is involved in the recruitment of mononuclear cells by a mechanism called IL-6 trans-signaling. It had been speculated that sIL-6R was generated at the site of inflammation by shedding from neutrophils via activation of the metalloprotease ADAM17. Attempts to genetically delete the floxed ADAM17 gene selectively in myeloid cells infiltrating an air pouch cavity upon injection of carrageenan failed because in transgenic mice, LysMcre did not lead to appreciable loss of the ADAM17 protein in these cells. We therefore used ADAM17 hypomorphic mice, which only express ~5% of ADAM17 wild-type levels in all tissues and show virtually no shedding of all tested ADAM17 substrates, to clarify the role of ADAM17 during local inflammation in the murine air pouch model. In the present study, we demonstrate that although IL-6 and the trans signaling mechanism is mandatory for cellular infiltration in this model, it is not ADAM17-mediated shedding of IL-6R within the pouch that orchestrates this inflammatory process. Instead, we demonstrate that sIL-6R is infiltrating from the circulation in an ADAM17-independent process. Our data suggest that this infiltrating sIL-6R, which is needed for IL-6 trans-signaling, is involved in the controlled resolution of an acute inflammatory episode.

AB - Adipose tissue (AT) macrophages (ATMs) are key players for regulation of AT homeostasis and obesity-related metabolic disorders. However, the phenotypes of human ATMs and regulatory mechanisms of their polarization have not been clearly described. In this study, we investigated human ATMs in both abdominal visceral AT and s.c. AT and proposed an 11beta-hydroxysteroid dehydrogenase type 1 (11beta HSD1)-glucocorticoid receptor regulatory axis that might dictate M1/M2 polarization in ATMs. The accumulation of CD11c+CD163+ ATMs in both visceral AT and s.c. AT of obese individuals was confirmed at the cellular level and was found to be clearly correlated with body mass index and production of reactive oxygen species. Using our in vitro system where human peripheral blood monocytes (hPBMs) were cocultured with Simpson-Golabi-Behmel syndrome adipocytes, M1/M2 polarization was found to be dependent on 11beta-HSD1, an intracellular glucocorticoid reactivating enzyme. Exposure of hPBMs to cortisol-induced expression of CD163 and RU-486, a glucocorticoid receptor antagonist, significantly abrogated CD163 expression through coculture of mature adipocytes with hPBMs. Moreover, 11beta-HSD1 was expressed in crown ATMs in obese AT. Importantly, conditioned medium from coculture of adipocytes with hPBMs enhanced proliferation of human breast cancer MCF7 and MDA-MB-231 cells. In summary, the phenotypic switch of ATMs from M2 to mixed M1/M2 phenotype occurred through differentiation of adipocytes in obese individuals, and upregulation of intracellular 11beta-HSD1 might play a role in the process. PMID- 27698012 TI - Von Willebrand Factor Interacts with Surface-Bound C1q and Induces Platelet Rolling. AB - Premature atherosclerosis and thrombotic complications are major causes of morbidity and mortality in patients with systemic lupus erythematosus (SLE). However, the high incidence of these complications cannot be explained by traditional risk factors alone, suggesting direct effects of an activated immune system on hemostasis. The unexpected nucleotide sequence homology between SLE patient-derived autoantibodies against complement C1q (Fab anti-C1q) and von Willebrand factor (VWF) led us to investigate a potential interaction between the complement and hemostatic systems on the level of initiating molecules. VWF was found to bind to surface-bound C1q under static conditions. The binding could specifically be inhibited by Fab anti-C1q and C1q-derived peptides. Under shear stress the C1q-VWF interaction was enhanced, resembling the binding of VWF to collagen I. Additionally, we could show that C1q-VWF complexes induced platelet rolling and firm adhesion. Furthermore, we observed VWF binding to C1q-positive apoptotic microparticles and cholesterol crystals, as well as increased VWF deposition in C1q-positive glomeruli of SLE patients compared with control nephropathy. We show, to our knowledge for the first time, binding of VWF to C1q and thus a direct interaction between starter molecules of hemostasis and the classical pathway of complement. This direct interaction might contribute to the pathogenic mechanisms in complement-mediated, inflammatory diseases. PMID- 27698013 TI - Relationships Between Older Drivers' Cognitive Abilities as Assessed on the MoCA and Glance Patterns During Visual-Manual Radio Tuning While Driving. AB - Objective: Research has established that long off-road glances increase crash risk, and other work has shown increased off-road glance behavior in older drivers. This study investigated the relationship between older drivers' (M = 66.3, range 61-69 years) cognitive abilities and the duration of off-road glances while engaged in secondary visual-manual activities. Method: Twenty-two drivers completed the Montreal Cognitive Assessment (MoCA) prior to driving an instrumented vehicle and completing a set of radio-tuning tasks. Glance behavior was recorded and manually coded into 7 glance regions (toward the forward roadway, instrument cluster, center stack, rearview mirror, left, right, and other). Results: On average, older drivers with higher MoCA scores used shorter glances and glanced away from the forward roadway for less total time when manually tuning the radio. Discussion: These findings suggest that lower MoCA scores may represent a driving force behind the "age" differences reported in earlier studies of off-road glance behavior. Questions are raised concerning the identification of MoCA scores that might be used as inclusion cut-points in driving research and in identifying individuals needing further evaluation related to suitability for continuance of driving. PMID- 27698020 TI - Interleukin-17 Is Required for Control of Chronic Lung Infection Caused by Pseudomonas aeruginosa. AB - Chronic pulmonary infection with Pseudomonas aeruginosa is a feature of cystic fibrosis (CF) and other chronic lung diseases. Cytokines of the interleukin-17 (IL-17) family have been proposed as important in the host response to P. aeruginosa infection through their role in augmenting antibacterial immune responses, although their proinflammatory effect may contribute to lung damage that occurs as a result of chronic infection. We set out to explore the role of IL-17 in the host response to chronic P. aeruginosa infection. We used a murine model of chronic pulmonary infection with CF-related strains of P. aeruginosa We demonstrate that IL-17 cytokine signaling is essential for mouse survival and prevention of chronic infection at 2 weeks postinoculation using two different P. aeruginosa strains. Following infection, there was a marked expansion of cells within mediastinal lymph nodes, comprised mainly of innate lymphoid cells (ILCs); ~90% of IL-17-producing (IL-17+) cells had markers consistent with group 3 ILCs. A smaller percentage of IL-17+ cells had markers consistent with a B1 phenotype. In lung homogenates harvested 14 days following infection, there was a significant expansion of IL-17+ cells; about 50% of these were CD3+, split equally between CD4+ Th17 cells and gammadelta T cells, while the CD3- IL-17+ cells were almost exclusively group 3 ILCs. Further experiments with B cell deficient mice showed that B cell production of IL-17 or natural antibodies did not provide any defense against chronic P. aeruginosa infection. Thus, IL-17 rather than antibody is a key element in host defense against chronic pulmonary infection with P. aeruginosa. PMID- 27698019 TI - RalF-Mediated Activation of Arf6 Controls Rickettsia typhi Invasion by Co-Opting Phosphoinositol Metabolism. AB - Rickettsiae are obligate intracellular pathogens that induce their uptake into nonphagocytic cells; however, the events instigating this process are incompletely understood. Importantly, diverse Rickettsia species are predicted to utilize divergent mechanisms to colonize host cells, as nearly all adhesins and effectors involved in host cell entry are differentially encoded in diverse Rickettsia species. One particular effector, RalF, a Sec7 domain-containing protein that functions as a guanine nucleotide exchange factor of ADP ribosylation factors (Arfs), is critical for Rickettsia typhi (typhus group rickettsiae) entry but pseudogenized or absent from spotted fever group rickettsiae. Secreted early during R. typhi infection, RalF localizes to the host plasma membrane and interacts with host ADP-ribosylation factor 6 (Arf6). Herein, we demonstrate that RalF activates Arf6, a process reliant on a conserved Glu within the RalF Sec7 domain. Furthermore, Arf6 is activated early during infection, with GTP-bound Arf6 localized to the R. typhi entry foci. The regulation of phosphatidylinositol 4-phosphate 5-kinase (PIP5K), which generates PI(4,5)P2, by activated Arf6 is instrumental for bacterial entry, corresponding to the requirement of PI(4,5)P2 for R. typhi entry. PI(3,4,5)P3 is then synthesized at the entry foci, followed by the accumulation of PI(3)P on the short-lived vacuole. Inhibition of phosphoinositide 3-kinases, responsible for the synthesis of PI(3,4,5)P3 and PI(3)P, negatively affects R. typhi infection. Collectively, these results identify RalF as the first bacterial effector to directly activate Arf6, a process that initiates alterations in phosphoinositol metabolism critical for a lineage-specific Rickettsia entry mechanism.

AB - Trypanosoma cruzi is the causative agent of chronic chagasic cardiomyopathy. Why macrophages (mphis), the early responders to infection, fail to achieve parasite clearance is not known. Mouse (RAW 264.7) and human (THP-1 and primary) mphis were infected for 3 h and 18 h with T. cruzi TcI isolates, SylvioX10/4 (SYL, virulent) and TCC (nonpathogenic), which represent mphi stimulation and infection states, respectively. Mphis incubated with lipopolysaccharide and gamma interferon (LPS/IFN-gamma) and with interleukin-4 (IL-4) were used as controls. We monitored the cytokine profile (using enzyme-linked immunosorbent assay [ELISA]), reactive oxygen species (ROS; fluorescent probes), nitric oxide (.NO; Griess assay), and metabolic state using a custom-designed mitoxosome array and Seahorse XF24 Analyzer. LPS/IFN-gamma treatment of mphis elicited a potent increase in production of tumor necrosis alpha (TNF-alpha) at 3 h and of ROS and .NO by 18 h. Upon SYL infection, murine mphis elicited an inflammatory cytokine profile (TNF-alpha ? TGF-beta + IL-10) and low levels of .NO and ROS production. LPS/IFN-gamma treatment resulted in the inhibition of oxidative metabolism at the gene expression and functional levels and a switch to the glycolytic pathway in mphis, while IL-4-treated mphis utilized oxidative metabolism to meet energy demands. SYL infection resulted in an intermediate functional metabolic state with increased mitoxosome gene expression and glycolysis, and IFN-gamma addition shut down the oxidative metabolism in SYL-infected mphis. Further, TCC- and SYL stimulated mphis exhibited similar levels of cell proliferation and production of TNF-alpha and ROS, while TCC-stimulated mphis exhibited up to 2-fold-higher levels of oxidative metabolism and .NO production than SYL-infected mphis. Inhibiting ATP-coupled O2 consumption suppressed the .NO generation in SYL infected mphis. Mitochondrial oxygen consumption constitutes a mechanism for stimulating .NO production in mphis during T. cruzi infection. Enhancing the oxidative metabolism provides an opportunity for increased .NO production and pathogen clearance by mphis to limit disease progression.

PMID- 27698022 TI - Genetic Determinants of Salmonella enterica Serovar Typhimurium Proliferation in the Cytosol of Epithelial Cells. AB - Intestinal epithelial cells provide an important colonization niche for Salmonella enterica serovar Typhimurium during gastrointestinal infections. In infected epithelial cells, a subpopulation of S Typhimurium bacteria damage their internalization vacuole, leading to escape from the Salmonella-containing vacuole (SCV) and extensive proliferation in the cytosol. Little is known about the bacterial determinants of nascent SCV lysis and subsequent survival and replication of Salmonella in the cytosol. To pinpoint S Typhimurium virulence factors responsible for these steps in the intracellular infectious cycle, we screened a S Typhimurium multigene deletion library in Caco-2 C2Bbe1 and HeLa epithelial cells for mutants that had an altered proportion of cytosolic bacteria compared to the wild type. We used a gentamicin protection assay in combination with a chloroquine resistance assay to quantify total and cytosolic bacteria, respectively, for each strain. Mutants of three S Typhimurium genes, STM1461 (ydgT), STM2829 (recA), and STM3952 (corA), had reduced cytosolic proliferation compared to wild-type bacteria, and one gene, STM2120 (asmA), displayed increased cytosolic replication. None of the mutants were affected for lysis of the nascent SCV or vacuolar replication in epithelial cells, indicating that these genes are specifically required for survival and proliferation of S Typhimurium in the epithelial cell cytosol. These are the first genes identified to contribute to this step of the S Typhimurium infectious cycle. PMID- 27698026 TI - Incentive payments: the correct lesson.

AB - STUDY QUESTION: Can host fertility be rescued by grafting of a fragment of a healthy ovary soon after chemotherapy? SUMMARY ANSWER: We found that grafting a green fluorescent protein (GFP)-positive fragment from a healthy isogenic ovary to the left ovary of a chemo-treated host rescued function and fertility of the grafted host ovary, and resulted in the production of host-derived offspring as late as the sixth litter after chemotherapy (CTx) treatment, whereas none of the ungrafted controls produced a second litter. WHAT IS KNOWN ALREADY: In women and girls undergoing chemotherapy, infertility and premature ovarian failure are frequent outcomes. There are accumulating reports of improved endocrine function after autotransplantation of an ovarian fragment, raising the possibility that the transplant is beneficial to the endogenous ovary. STUDY DESIGN, SIZE, DURATION: We first established a CTx treatment regimen that resulted in the permanent loss of fertility in 100% of female mice of the FVB inbred strain. We grafted an isogenic ovary fragment from a healthy female homozygous for a GFP transgene to the left ovary of 100 CTx-treated hosts, and compared fertility to 39 ungrafted controls in 6 months of continuous matings, using GFP to distinguish offspring derived from the graft, and those derived from the host. PARTICIPANTS/MATERIALS, SETTING, METHODS: Immunofluoresece and western blot analysis of 39 treated ovaries during and 15 days after CTx treatment revealed elevated apoptosis, rapid loss of granulosa cells and an increased recruitment of growing follicles. Using immunofluorescence and confocal imaging, we tracked the outcome of the grafted tissue over 4 months and its effect on the adjacent and contralateral ovary of the host. MAIN RESULTS AND THE ROLE OF CHANCE: Fifty-three percent of grafted females produced a second litter whereas none of the ungrafted females produced a second litter. The likelihood that this could occur by chance is very low (P < 0.0001). LIMITATIONS, REASONS FOR CAUTION: These results are shown only in mice, and whether or how they might apply to chemotherapy patients subjected to different CTx regimens is not yet clear. WIDER IMPLICATIONS OF THE FINDINGS: Our experiments prove that rescue of a chemo-treated ovary is possible, and establish a system to investigate the mechanism of rescue and to identify the factors responsible with the long-term goal of developing therapies for preservation of ovarian endocrine function and fertility in women undergoing chemotherapy.

AB - We discuss a unified mesoscale framework (chimaera) for the simulation of complex states of flowing matter across scales of motion. The chimaera framework can deal with each of the three macro-meso-micro levels through suitable 'mutations' of the basic mesoscale formulation. The idea is illustrated through selected simulations of complex micro- and nanoscale flows.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'. PMID- 27698030 TI - Cytoskeletal Integrators: The Spectrin Superfamily. AB - This review discusses the spectrin superfamily of proteins that function to connect cytoskeletal elements to each other, the cell membrane, and the nucleus. The signature domain is the spectrin repeat, a 106-122-amino-acid segment comprising three alpha-helices. alpha-actinin is considered to be the ancestral protein and functions to cross-link actin filaments. It then evolved to generate spectrin and dystrophin that function to link the actin cytoskeleton to the cell membrane, as well as the spectraplakins and plakins that link cytoskeletal elements to each other and to junctional complexes. A final class comprises the nesprins, which are able to bind to the nuclear membrane. This review discusses the domain organization of the various spectrin family members, their roles in protein-protein interactions, and their roles in disease, as determined from mutations, and it also describes the functional roles of the family members as determined from null phenotypes. PMID- 27698032 TI - Improved insights into protein thermal stability: from the molecular to the structurome scale. AB - Despite the intense efforts of the last decades to understand the thermal stability of proteins, the mechanisms responsible for its modulation still remain debated. In this investigation, we tackle this issue by showing how a multiscale perspective can yield new insights. With the help of temperature-dependent statistical potentials, we analysed some amino acid interactions at the molecular level, which are suggested to be relevant for the enhancement of thermal resistance. We then investigated the thermal stability at the protein level by quantifying its modification upon amino acid substitutions. Finally, a large scale analysis of protein stability-at the structurome level-contributed to the clarification of the relation between stability and natural evolution, thereby showing that the mutational profile of proteins differs according to their thermal properties. Some considerations on how the multiscale approach could help in unravelling the protein stability mechanisms are briefly discussed.This article is part of the themed issue 'Multiscale modelling at the physics chemistry-biology interface'. PMID- 27698029 TI - Cell Signaling and Stress Responses. AB - Stress-signaling pathways are evolutionarily conserved and play an important role in the maintenance of homeostasis. These pathways are also critical for adaptation to new cellular environments. The endoplasmic reticulum (ER) unfolded protein response (UPR) is activated by biosynthetic stress and leads to a compensatory increase in ER function. The JNK and p38 MAPK signaling pathways control adaptive responses to intracellular and extracellular stresses, including environmental changes such as UV light, heat, and hyperosmotic conditions, and exposure to inflammatory cytokines. Metabolic stress caused by a high-fat diet represents an example of a stimulus that coordinately activates both the UPR and JNK/p38 signaling pathways. Chronic activation of these stress-response pathways ultimately causes metabolic changes associated with obesity and altered insulin sensitivity. Stress-signaling pathways, therefore, represent potential targets for therapeutic intervention in the metabolic stress response and other disease processes.

AB - Diverse organophosphate hydrolases have convergently evolved the ability to hydrolyse man-made organophosphates. Thus, these enzymes are attractive model systems for studying the factors shaping enzyme functional evolution. Methyl parathion hydrolase (MPH) is an enzyme from the metallo-beta-lactamase superfamily, which hydrolyses a wide range of organophosphate, aryl ester and lactone substrates. In addition, MPH demonstrates metal-ion-dependent selectivity patterns. The origins of this remain unclear, but are linked to open questions about the more general role of metal ions in functional evolution and divergence within enzyme superfamilies. Here, we present detailed mechanistic studies of the paraoxonase and arylesterase activities of MPH complexed with five different transition metal ions, and demonstrate that the hydrolysis reactions proceed via similar pathways and transition states. However, while it is possible to discern a clear structural origin for the selectivity between different substrates, the selectivity between different metal ions appears to lie instead in the distinct electrostatic properties of the metal ions themselves, which causes subtle changes in transition state geometries and metal-metal distances at the transition state rather than significant structural changes in the active site. While subtle, these differences can be significant for shaping the metal-ion dependent activity patterns observed for this enzyme.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'.

AB - We report the synthesis of magnesium-aluminium layered double hydroxide (LDH) using a reaction-diffusion framework (RDF) that exploits the multiscale coupling of molecular diffusion with chemical reactions, nucleation and growth of crystals. In an RDF, the hydroxide anions are allowed to diffuse into an organic gel matrix containing the salt mixture needed for the precipitation of the LDH. The chemical structure and composition of the synthesized magnesium-aluminium LDHs are determined using powder X-ray diffraction (PXRD), thermo-gravimetric analysis, differential scanning calorimetry, solid-state nuclear magnetic resonance (SSNMR), Fourier transform infrared and energy dispersive X-ray spectroscopy. This novel technique also allows the investigation of the mechanism of intercalation of some fluorescent probes, such as the neutral three dimensional rhodamine B (RhB) and the negatively charged two-dimensional 8 hydroxypyrene-1,3,6-trisulfonic acid (HPTS), using in situ steady-state fluorescence spectroscopy. The incorporation of these organic dyes inside the interlayer region of the LDH is confirmed via fluorescence microscopy, solid state lifetime, SSNMR and PXRD. The activation energies of intercalation of the corresponding molecules (RhB and HPTS) are computed and exhibit dependence on the geometry of the involved probe (two or three dimensions), the charge of the fluorescent molecule (anionic, cationic or neutral) and the cationic ratio of the corresponding LDH.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'. PMID- 27698035 TI - Big data need big theory too. AB - The current interest in big data, machine learning and data analytics has generated the widespread impression that such methods are capable of solving most problems without the need for conventional scientific methods of inquiry. Interest in these methods is intensifying, accelerated by the ease with which digitized data can be acquired in virtually all fields of endeavour, from science, healthcare and cybersecurity to economics, social sciences and the humanities. In multiscale modelling, machine learning appears to provide a shortcut to reveal correlations of arbitrary complexity between processes at the atomic, molecular, meso- and macroscales. Here, we point out the weaknesses of pure big data approaches with particular focus on biology and medicine, which fail to provide conceptual accounts for the processes to which they are applied. No matter their 'depth' and the sophistication of data-driven methods, such as artificial neural nets, in the end they merely fit curves to existing data. Not only do these methods invariably require far larger quantities of data than anticipated by big data aficionados in order to produce statistically reliable results, but they can also fail in circumstances beyond the range of the data used to train them because they are not designed to model the structural characteristics of the underlying system. We argue that it is vital to use theory as a guide to experimental design for maximal efficiency of data collection and to produce reliable predictive models and conceptual knowledge. Rather than continuing to fund, pursue and promote 'blind' big data projects with massive budgets, we call for more funding to be allocated to the elucidation of the multiscale and stochastic processes controlling the behaviour of complex systems, including those of life, medicine and healthcare.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'.

AB - This discussion paper introduces the concept of the Virtual Artery as a multiscale model for arterial physiology and pathologies at the physics-chemistry biology (PCB) interface. The cellular level is identified as the mesoscopic level, and we argue that by coupling cell-based models with other relevant models on the macro- and microscale, a versatile model of arterial health and disease can be composed. We review the necessary ingredients, both models of arteries at many different scales, as well as generic methods to compose multiscale models. Next, we discuss how this can be combined into the virtual artery. Finally, we argue that the concept of models at the PCB interface could or perhaps should become a powerful paradigm, not only as in our case for studying physiology, but also for many other systems that have such PCB interfaces.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'.

AB - Active media, whose constituents are able to move autonomously, display novel features that differ from those of equilibrium systems. In addition to naturally occurring active systems such as populations of swimming bacteria, active systems of synthetic self-propelled nanomotors have been developed. These synthetic systems are interesting because of their potential applications in a variety of fields. Janus particles, synthetic motors of spherical geometry with one hemisphere that catalyses the conversion of fuel to product and one non-catalytic hemisphere, can propel themselves in solution by self-diffusiophoresis. In this mechanism, the concentration gradient generated by the asymmetric catalytic activity leads to a force on the motor that induces fluid flows in the surrounding medium. These fluid flows are studied in detail through microscopic simulations of Janus motor motion and continuum theory. It is shown that continuum theory is able to capture many, but not all, features of the dynamics of the Janus motor and the velocity fields of the fluid.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'.

PMID- 27698040 TI - Generation of mechanical force by grafted polyelectrolytes in an electric field: application to polyelectrolyte-based nano-devices. AB - We analyse theoretically and by means of molecular dynamics (MD) simulations the generation of mechanical force by a polyelectrolyte (PE) chain grafted to a plane. The PE is exposed to an external electric field that favours its adsorption on the plane. The free end of the chain is linked to a deformable target body. By varying the field, one can alter the length of the non-adsorbed part of the chain. This entails variation of the deformation of the target body and hence variation of the force arising in the body. Our theoretical predictions for the generated force are in very good agreement with the MD data. Using the theory developed for the generated force, we study the effectiveness of possible PE-based nano-vices, composed of two clenching planes connected by PEs and exposed to an external electric field. We exploit the Cundall-Strack solid friction model to describe the friction between a particle and the clenching planes. We compute the diffusion coefficient of a clenched particle and show that it drastically decreases even in weak applied fields. This demonstrates the efficacy of the PE-based nano-vices, which may be a possible alternative to the existing nanotube nano-tweezers and optical tweezers.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'. PMID- 27698038 TI - A perspective on bridging scales and design of models using low-dimensional manifolds and data-driven model inference. AB - Systems in nature capable of collective behaviour are nonlinear, operating across several scales. Yet our ability to account for their collective dynamics differs in physics, chemistry and biology. Here, we briefly review the similarities and differences between mathematical modelling of adaptive living systems versus physico-chemical systems. We find that physics-based chemistry modelling and computational neuroscience have a shared interest in developing techniques for model reductions aiming at the identification of a reduced subsystem or slow manifold, capturing the effective dynamics. By contrast, as relations and kinetics between biological molecules are less characterized, current quantitative analysis under the umbrella of bioinformatics focuses on signal extraction, correlation, regression and machine-learning analysis. We argue that model reduction analysis and the ensuing identification of manifolds bridges physics and biology. Furthermore, modelling living systems presents deep challenges as how to reconcile rich molecular data with inherent modelling uncertainties (formalism, variables selection and model parameters). We anticipate a new generative data-driven modelling paradigm constrained by identified governing principles extracted from low-dimensional manifold analysis. The rise of a new generation of models will ultimately connect biology to quantitative mechanistic descriptions, thereby setting the stage for investigating the character of the model language and principles driving living systems.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'. PMID- 27698041 TI - Evaluating dispersion forces for optimization of van der Waals complexes using a non-empirical functional. AB - Modelling dispersion interactions with traditional density functional theory (DFT) is a challenge that has been extensively addressed in the past decade. The exchange-dipole moment (XDM), among others, is a non-empirical add-on dispersion correction model in DFT. The functional PW86+PBE+XDM for exchange, correlation and dispersion, respectively, compromises an accurate functional for thermochemistry and for van der Waals (vdW) complexes at equilibrium and non equilibrium geometries. To use this functional in optimizing vdW complexes, rather than computing single point energies, it is necessary to evaluate accurate forces. The purpose of this paper is to validate that, along the potential energy surface, the distance at which the energy is minimum is commensurate with the distance at which the forces vanish to zero. This test was validated for 10 rare gas diatomic molecules using various integration grids and different convergence criteria. It was found that the use of either convergence criterion, 10-6 or 10 8, in Gaussian09, does not affect the accuracy of computed optimal distances and binding energies. An ultra-fine grid needs to be used when computing accurate energies using generalized gradient approximation functionals.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'. PMID- 27698042 TI - Reaction-diffusion basis of retroviral infectivity. AB - Retrovirus particle (virion) infectivity requires diffusion and clustering of multiple transmembrane envelope proteins (Env3) on the virion exterior, yet is triggered by protease-dependent degradation of a partially occluding, membrane bound Gag polyprotein lattice on the virion interior. The physical mechanism underlying such coupling is unclear and only indirectly accessible via experiment. Modelling stands to provide insight but the required spatio-temporal range far exceeds current accessibility by all-atom or even coarse-grained molecular dynamics simulations. Nor do such approaches account for chemical reactions, while conversely, reaction kinetics approaches handle neither diffusion nor clustering. Here, a recently developed multiscale approach is considered that applies an ultra-coarse-graining scheme to treat entire proteins at near-single particle resolution, but which also couples chemical reactions with diffusion and interactions. A model is developed of Env3 molecules embedded in a truncated Gag lattice composed of membrane-bound matrix proteins linked to capsid subunits, with freely diffusing protease molecules. Simulations suggest that in the presence of Gag but in the absence of lateral lattice-forming interactions, Env3 diffuses comparably to Gag-absent Env3 Initial immobility of Env3 is conferred through lateral caging by matrix trimers vertically coupled to the underlying hexameric capsid layer. Gag cleavage by protease vertically decouples the matrix and capsid layers, induces both matrix and Env3 diffusion, and permits Env3 clustering. Spreading across the entire membrane surface reduces crowding, in turn, enhancing the effect and promoting infectivity.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'. PMID- 27698043 TI - Kinetics and thermodynamics of living copolymerization processes. AB - Theoretical advances are reported on the kinetics and thermodynamics of free and template-directed living copolymerizations. Until recently, the kinetic theory of these processes had only been established in the fully irreversible regime, in which the attachment rates are only considered. However, the entropy production is infinite in this regime and the approach to thermodynamic equilibrium cannot be investigated. For this purpose, the detachment rates should also be included. Inspite of this complication, the kinetics can be exactly solved in the regimes of steady growth and depolymerization. In this way, analytical expressions are obtained for the mean growth velocity, the statistical properties of the copolymer sequences, as well as the thermodynamic entropy production. The results apply to DNA replication, transcription and translation, allowing us to understand important aspects of molecular evolution.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'. PMID- 27698044 TI - Thermodynamics of adaptive molecular resolution. AB - A relatively general thermodynamic formalism for adaptive molecular resolution (AMR) is presented.

AB - Hybrid particle-continuum computational frameworks permit the simulation of gas flows by locally adjusting the resolution to the degree of non-equilibrium displayed by the flow in different regions of space and time. In this work, we present a new scheme that couples the direct simulation Monte Carlo (DSMC) with the lattice Boltzmann (LB) method in the limit of isothermal flows. The former handles strong non-equilibrium effects, as they typically occur in the vicinity of solid boundaries, whereas the latter is in charge of the bulk flow, where non equilibrium can be dealt with perturbatively, i.e. according to Navier-Stokes hydrodynamics. The proposed concurrent multiscale method is applied to the dilute gas Couette flow, showing major computational gains when compared with the full DSMC scenarios. In addition, it is shown that the coupling with LB in the bulk flow can speed up the DSMC treatment of the Knudsen layer with respect to the full DSMC case. In other words, LB acts as a DSMC accelerator.This article is part of the themed issue 'Multiscale modelling at the physics-chemistry-biology interface'.

AB - Identifying the key factor involved in cardiac remodeling is critically important for developing novel strategies to protect against heart failure. Here, the role of Mnk1 (mitogen-activated protein kinase-interacting kinase 1) in cardiac remodeling was clarified. Cardiac remodeling was induced by transverse aortic constriction in Mnk1-knockout mice and their wild-type control mice. After 4 weeks of transverse aortic constriction, Mnk1-knockout mice developed exaggerated cardiac hypertrophy, fibrosis, dysfunction, and cardiomyocyte apoptosis and showed increased ERK1/2 (extracellular signal-regulated kinase 1/2) activation along with reduced sprouty2 expression. In line with the in vivo studies, Mnk1 knockdown by Mnk1 siRNA transfection induced exaggerated angiotensin II-induced cardiomyocyte hypertrophy in neonatal rat ventricular myocytes (NRVMs). Moreover, adenovirus-mediated overexpression of Mnk1 in NRVMs protected cardiomyocytes from angiotensin II-induced hypertrophy. In addition, overexpression of sprouty2 rescued NRVMs with Mnk1 knockdown from angiotensin II-induced hypertrophy. In accordance with the in vivo studies, as compared with the control group, Mnk1 knockdown led to hyperphosphorylation of ERK1/2 and suppression of the sprouty2 expression in angiotensin II-treated NRVMs; furthermore, Mnk1 overexpression led to hypophosphorylation of ERK1/2 in angiotensin II-treated NRVMs. In addition, sprouty2 overexpression suppressed the activation of ERK1/2 in angiotensin II treated NRVMs with Mnk1 knockdown. Impressively, MnK1-knockout mice with overexpression of sprouty2 exhibited signs of a blunted cardiac hypertrophic response. Mnk1 likely carries out a suppressive function in cardiac hypertrophy via regulating the sprouty2/ERK1/2 pathway. It implicates Mnk1 in the development of cardiac remodeling. PMID- 27698062 TI - Agonistic Autoantibodies to the Angiotensin II Type 1 Receptor Enhance Angiotensin II-Induced Renal Vascular Sensitivity and Reduce Renal Function During Pregnancy. AB - Preeclamptic women produce agonistic autoantibodies to the angiotensin II type 1 receptor (AT1-AA) and exhibit increased blood pressure (mean arterial pressure), vascular sensitivity to angiotensin II (ANG II), and display a decrease in renal function. The objective of this study was to examine the renal hemodynamic changes during pregnancy in the presence of AT1-AAs with or without a slow pressor dose of ANG II. In this study, mean arterial pressure was elevated in all pregnant rats treated with ANG II with or without AT1-AA. Glomerular filtration rate was reduced from 1.90+/-0.16 mL/min in normal pregnant (NP) to 1.20+/-0.08 in ANG II+AT1-AA rats. Renal blood flow was decreased in ANG II+AT1-AA versus NP rats to 7.4+/-1.09 versus 15.4+/-1.75 mL/min. Renal vascular resistance was drastically increased between ANG II+AT1-AA versus NP rats (18.4+/-2.91 versus 6.4+/-0.77 mm Hg/mL per minute). Isoprostane excretion was increased by 3.5-fold in ANG II+AT1-AA versus NP (1160+/-321 versus 323+/-52 pg/mL). In conclusion, ANG II and AT1-AA together significantly decrease glomerular filtration rate by 37% and renal blood flow by 50% and caused a 3-fold increase in renal vascular resistance and isoprostane levels versus NP rats. These data indicate the importance of AT1-AAs to enhance ANG II-induced renal vasoconstriction and reduce renal function as mechanisms to cause hypertension as observed during preeclampsia. PMID- 27698063 TI - Extent of Vascular Remodeling Is Dependent on the Balance Between Estrogen Receptor alpha and G-Protein-Coupled Estrogen Receptor. AB - Estrogens are important regulators of cardiovascular function. Some of estrogen's cardiovascular effects are mediated by a G-protein-coupled receptor mechanism, namely, G-protein-coupled estrogen receptor (GPER). Estradiol-mediated regulation of vascular cell programmed cell death reflects the balance of the opposing actions of GPER versus estrogen receptor alpha (ERalpha). However, the significance of these opposing actions on the regulation of vascular smooth muscle cell proliferation or migration in vitro is unclear, and the significance in vivo is unknown. To determine the effects of GPER activation in vitro, we studied rat aortic vascular smooth muscle cells maintained in primary culture. GPER was reintroduced using adenoviral gene transfer. Both estradiol and G1, a GPER agonist, inhibited both proliferation and cell migration effects that were blocked by the GPER antagonist, G15. To determine the importance of the GPER ERalpha balance in regulating vascular remodeling in a rat model of carotid ligation, we studied the effects of upregulation of GPER expression versus downregulation of ERalpha. Reintroduction of GPER significantly attenuated the extent of medial hypertrophy and attenuated the extent of CD45 labeling. Downregulation of ERalpha expression comparably attenuated the extent of medial hypertrophy and inflammation after carotid ligation. These studies demonstrate that the balance between GPER and ERalpha regulates vascular remodeling. Receptor specific modulation of estrogen's effects may be an important new approach in modifying vascular remodeling in both acute settings like vascular injury and perhaps in longer term regulation like in hypertension.

AB - The effects of fluid shear stress (FSS) on the human syncytiotrophoblast and its biological functions have never been studied. During pregnancy, the syncytiotrophoblast is the main source of placental growth factor (PlGF), a proangiogenic factor involved in the placental angiogenesis and the vascular adaptation to pregnancy. The role of FSS in regulating PlGF expression in syncytiotrophoblasts is unknown. We investigated the impact of FSS on the production and secretion of the PlGF by the human syncytiotrophoblasts in primary cell culture. Laminar and continuous FSS (1 dyn cm-2) was applied to human syncytiotrophoblasts cultured in a parallel-plate flow chambers. Secreted levels of PlGF, sFlt-1 (soluble fms-like tyrosin kinase-1), and prostaglandin E2 were tested by immunologic assay. PlGF levels of mRNA and intracellular protein were examined by RT-PCR and Western blot, respectively. Intracellular cAMP levels were examined by time-resolved fluorescence resonance energy transfer cAMP accumulation assay. Production of cAMP and PlGF secretion was significantly increased in FSS conditions compared with static conditions. Western blot analysis of cell extracts exposed to FSS showed an increased phosphorylation of protein kinase A substrates and cAMP response element-binding protein on serine 133. FSS-induced phosphorylation of cAMP response element-binding protein and upregulation of PlGF were prevented by inhibition of protein kinase A with H89 (3 MUmol/L). FSS also triggers intracellular calcium flux, which increases the synthesis and release of prostaglandin E2. The enhanced intracellular cAMP in FSS conditions was blocked by COX1/COX2 (cyclooxygenase) inhibitors, suggesting that the increase in prostaglandin E2 production could activate the cAMP/protein kinase A pathway in an autocrine/paracrine fashion. FSS activates the cAMP/protein kinase A pathway leading to upregulation of PlGF in human syncytiotrophoblast.

AB - Renal sympathetic denervation (RDNx) has emerged as a novel therapy for hypertension; however, the therapeutic mechanisms remain unclear. Efferent renal sympathetic nerve activity has recently been implicated in trafficking renal inflammatory immune cells and inflammatory chemokine and cytokine release. Several of these inflammatory mediators are known to activate or sensitize afferent nerves. This study aimed to elucidate the roles of efferent and afferent renal nerves in renal inflammation and hypertension in the deoxycorticosterone acetate (DOCA) salt rat model. Uninephrectomized male Sprague-Dawley rats (275 300 g) underwent afferent-selective RDNx (n=10), total RDNx (n=10), or Sham (n=10) and were instrumented for the measurement of mean arterial pressure and heart rate by radiotelemetry. Rats received 100-mg DOCA (SC) and 0.9% saline for 21 days. Resting afferent renal nerve activity in DOCA and vehicle animals was measured after the treatment protocol. Renal tissue inflammation was assessed by renal cytokine content and T-cell infiltration and activation. Resting afferent renal nerve activity, expressed as a percent of peak afferent nerve activity, was substantially increased in DOCA than in vehicle (35.8+/-4.4 versus 15.3+/-2.8 %Amax). The DOCA-Sham hypertension (132+/-12 mm Hg) was attenuated by ~50% in both total RDNx (111+/-8 mm Hg) and afferent-selective RDNx (117+/-5 mm Hg) groups. Renal inflammation induced by DOCA salt was attenuated by total RDNx and unaffected by afferent-selective RDNx. These data suggest that afferent renal nerve activity may mediate the hypertensive response to DOCA salt, but inflammation may be mediated primarily by efferent renal sympathetic nerve activity. Also, resting afferent renal nerve activity is elevated in DOCA salt rats, which may highlight a crucial neural mechanism in the development and maintenance of hypertension. PMID- 27698067 TI - Cardiac Consequences of Autonomic Dysreflexia in Spinal Cord Injury. AB - Autonomic dysreflexia (AD), which describes episodic hypertension, is highly prevalent in people with spinal cord injury (SCI). In non-SCI, primary hypertension depresses cardiac contractile reserve via beta-adrenergic mechanisms. In this study, we investigated whether AD contributes to the impairment in cardiac contractile function that accompanies SCI. We induced SCI in rodents and stratified them into sham, SCI, or SCI plus repetitive induction of AD. At 6-week post-SCI, we assessed cardiac function using in vivo (speckle tracking echocardiography), ex vivo (working heart), and molecular approaches (Western blot). We also provide unique translational insight by comparing the relationship between the number of daily AD events and cardiac function in 14 individuals with cervical SCI. We found SCI and SCI plus repetitive induction of AD exhibited a reduction in left ventricular dimensions at 6-week post-SCI versus preinjury (P<0.049). Compared with sham, SCI exhibited a reduction in peak radial strain along with a down and rightward shift in the Starling curve (P<0.037), both of which were further depressed in SCI plus repetitive induction of AD (P<0.042). In response to beta-adrenergic stimulation, SCI plus repetitive induction of AD exhibited an attenuated increase in contractile indices (P<0.001), despite no differences in beta-receptor expression within the left ventricle. Our clinical data confirm our experimental findings by demonstrating significant associations between the number of daily AD events and markers of systolic and diastolic function along with left ventricular mechanics. Here, we provide the first evidence from a translational perspective that AD exerts insidious effects on cardiac function in rodents and humans with SCI. PMID- 27698068 TI - Cardioprotective Angiotensin-(1-7) Peptide Acts as a Natural-Biased Ligand at the Angiotensin II Type 1 Receptor. AB - Hyperactivity of the renin-angiotensin-aldosterone system through the angiotensin II (Ang II)/Ang II type 1 receptor (AT1-R) axis constitutes a hallmark of hypertension. Recent findings indicate that only a subset of AT1-R signaling pathways is cardiodeleterious, and their selective inhibition by biased ligands promotes therapeutic benefit. To date, only synthetic biased ligands have been described, and whether natural renin-angiotensin-aldosterone system peptides exhibit functional selectivity at AT1-R remains unknown. In this study, we systematically determined efficacy and potency of Ang II, Ang III, Ang IV, and Ang-(1-7) in AT1-R-expressing HEK293T cells on the activation of cardiodeleterious G-proteins and cardioprotective beta-arrestin2. Ang III and Ang IV fully activate similar G-proteins than Ang II, the prototypical AT1-R agonist, despite weaker potency of Ang IV. Interestingly, Ang-(1-7) that binds AT1-R fails to promote G-protein activation but behaves as a competitive antagonist for Ang II/Gi and Ang II/Gq pathways. Conversely, all renin-angiotensin-aldosterone system peptides act as agonists on the AT1-R/beta-arrestin2 axis but display biased activities relative to Ang II as indicated by their differences in potency and AT1-R/beta-arrestin2 intracellular routing. Importantly, we reveal Ang-(1-7) a known Mas receptor-specific ligand, as an AT1-R-biased agonist, selectively promoting beta-arrestin activation while blocking the detrimental Ang II/AT1-R/Gq axis. This original pharmacological profile of Ang-(1-7) at AT1-R, similar to that of synthetic AT1-R-biased agonists, could, in part, contribute to its cardiovascular benefits. Accordingly, in vivo, Ang-(1-7) counteracts the phenylephrine-induced aorta contraction, which was blunted in AT1-R knockout mice. Collectively, these data suggest that Ang-(1-7) natural-biased agonism at AT1-R could fine-tune the physiology of the renin-angiotensin-aldosterone system. PMID- 27698069 TI - Astrocytes Contribute to Angiotensin II Stimulation of Hypothalamic Neuronal Activity and Sympathetic Outflow. AB - Angiotensin II (AngII) is a key neuropeptide that acting within the brain hypothalamic paraventricular nucleus regulates neurohumoral outflow to the circulation. Moreover, an exacerbated AngII action within the paraventricular nucleus contributes to neurohumoral activation in hypertension. Although AngII effects involve changes in paraventricular nucleus neuronal activity, the precise underlying mechanisms, cellular targets, and distribution of AngII receptors within the paraventricular nucleus remain largely unknown. Thus, whether AngII effects involve direct actions on paraventricular neurons, or whether it acts via intermediary cells, such as astrocytes, is still controversial. To address this important gap in our knowledge, we used a multidisciplinary approach combining patch-clamp electrophysiology in presympathetic paraventricular neurons and astrocytes, along with in vivo sympathetic nerve recordings and astrocyte targeted gene manipulations. We present evidence for a novel mechanism underlying central AngII actions, which involves astrocytes as major intermediary cellular targets. We found that AngII type 1 receptor mRNA is expressed in paraventricular astrocytes. Moreover, we report that AngII inhibited glutamate transporter function, increasing in turn extracellular glutamate levels. This resulted in the activation of neuronal extrasynaptic NMDA (N-methyl-d-aspartate) receptors, increased presympathetic neuronal activity, enhanced sympathoexcitatory outflow, and increased blood pressure. Together, our studies support astrocytes as critical intermediary cell types mediating brain AngII regulation of the circulation and indicate that AngII-mediated neuronal and sympathoexcitatory effects are dependent on a unique neuroglial signaling modality involving nonsynaptic glutamate transmission. PMID- 27698070 TI - Arousal From Sleep and Sympathetic Excitation During Wakefulness. AB - Obstructive apnea during sleep elevates the set point for efferent sympathetic outflow during wakefulness. Such resetting is attributed to hypoxia-induced upregulation of peripheral chemoreceptor and brain stem sympathetic function. Whether recurrent arousal from sleep also influences daytime muscle sympathetic nerve activity is unknown. We therefore tested, in a cohort of 48 primarily nonsleepy, middle-aged, male (30) and female (18) volunteers (age: 59+/-1 years, mean+/-SE), the hypothesis that the frequency of arousals from sleep (arousal index) would relate to daytime muscle sympathetic burst incidence, independently of the frequency of apnea or its severity. Polysomnography identified 24 as having either no or mild obstructive sleep apnea (apnea-hypopnea index <15 events/h) and 24 with moderate-to-severe obstructive sleep apnea (apnea-hypopnea index >15 events/h). Burst incidence correlated significantly with arousal index (r=0.53; P<0.001), minimum oxygen saturation (r=-0.43; P=0.002), apnea-hypopnea index (r=0.41; P=0.004), age (r=0.36; P=0.013), and body mass index (r=0.33; P=0.022) but not with oxygen desaturation index (r=0.28; P=0.056). Arousal index was the single strongest predictor of muscle sympathetic nerve activity burst incidence, present in all best subsets regression models. The model with the highest adjusted R2 (0.456) incorporated arousal index, minimum oxygen saturation, age, body mass index, and oxygen desaturation index but not apnea hypopnea index. An apnea- and hypoxia-independent effect of sleep fragmentation on sympathetic discharge during wakefulness could contribute to intersubject variability, age-related increases in muscle sympathetic nerve activity, associations between sleep deprivation and insulin resistance or insomnia and future cardiovascular events, and residual adrenergic risk with persistence of hypertension should therapy eliminate obstructive apneas but not arousals. PMID- 27698071 TI - Nonmutational compensation of the fitness cost of antibiotic resistance in mycobacteria by overexpression of tlyA rRNA methylase. AB - Several studies over the last few decades have shown that antibiotic resistance mechanisms frequently confer a fitness cost and that these costs can be genetically ameliorated by intra- or extragenic second-site mutations, often without loss of resistance. Another, much less studied potential mechanism by which the fitness cost of antibiotic resistance could be reduced is via a regulatory response where the deleterious effect of the resistance mechanism is lowered by a physiological alteration that buffers the mutational effect. In mycobacteria, resistance to the clinically used tuberactinomycin antibiotic capreomycin involves loss-of-function mutations in rRNA methylase TlyA or point mutations in 16S rRNA (in particular the A1408G mutation). Both of these alterations result in resistance by reducing drug binding to the ribosome. Here we show that alterations of tlyA gene expression affect both antibiotic drug susceptibility and fitness cost of drug resistance. In particular, we demonstrate that the common resistance mutation A1408G is accompanied by a physiological change that involves increased expression of the tlyA gene. This gene encodes an enzyme that methylates neighboring 16S rRNA position C1409, and as a result of increased TlyA expression the fitness cost of the A1408G mutation is significantly reduced. Our findings suggest that in mycobacteria, a nonmutational mechanism (i.e., gene regulatory) can restore fitness to genetically resistant bacteria. Our results also point to a new and clinically relevant treatment strategy to combat evolution of resistance in multidrug-resistant tuberculosis. Thus, by utilizing antagonistic antibiotic interactions, resistance evolution could be reduced. PMID- 27698073 TI - Disclosure of donor conception in the era of non-anonymity: safeguarding and promoting the interests of donor-conceived individuals? AB - This article responds to a debate article published in Human Reproduction earlier this year. In that article, the authors suggested that parents should be encouraged to disclose the use of donor gametes to their children given rapid and widespread advances in genetic testing and sequencing. However, there is an urgent need to engage with the assertion that in this context, telling children about their donor conception both safeguards and promotes their interests, particularly if such disclosure is motivated by parents' anxieties about accidental discovery. Disclosure that is motivated by the notion of non-anonymity may also encourage parents to share misinformation about donors and encourage their children to have unrealistic expectations. Fertility professionals must remain mindful of these outcomes when discussing disclosure and the future implications of increasing access to genetic information with both prospective and current parents. It is strongly advised that future discussions about the end of donor anonymity are not conflated with the debate on disclosure. PMID- 27698072 TI - Rating Communication in GP Consultations: The Association Between Ratings Made by Patients and Trained Clinical Raters. AB - Patient evaluations of physician communication are widely used, but we know little about how these relate to professionally agreed norms of communication quality. We report an investigation into the association between patient assessments of communication quality and an observer-rated measure of communication competence. Consent was obtained to video record consultations with Family Practitioners in England, following which patients rated the physician's communication skills. A sample of consultation videos was subsequently evaluated by trained clinical raters using an instrument derived from the Calgary-Cambridge guide to the medical interview. Consultations scored highly for communication by clinical raters were also scored highly by patients. However, when clinical raters judged communication to be of lower quality, patient scores ranged from "poor" to "very good." Some patients may be inhibited from rating poor communication negatively. Patient evaluations can be useful for measuring relative performance of physicians' communication skills, but absolute scores should be interpreted with caution. PMID- 27698075 TI - 'Noisy, restless and incoherent': puerperal insanity at Dundee Lunatic Asylum. AB - Puerperal insanity has been described as a nineteenth-century diagnosis, entrenched in contemporary expectations of proper womanly behaviour. Drawing on detailed study of establishment registers and patient case notes, this paper examines the puerperal insanity diagnosis at Dundee Lunatic Asylum between 1820 and 1860. In particular, the study aims to consider whether the class or social status of the patients had a bearing on how their conditions were perceived and rationalized, and how far the puerperal insanity diagnosis, coloured by the values assigned to it by the medical officers, may have been reserved for some women and not for others. This examination of the diagnosis in a Scottish community, suggesting a contrast in the way that middle-class and working-class women were diagnosed at Dundee, engages with and expands on work on puerperal insanity elsewhere. PMID- 27698074 TI - Successful IVF pregnancy despite inadequate ovarian steroidogenesis due to congenital lipoid adrenal hyperplasia (CLAH): a case report. AB - Steroidogenic acute regulatory protein (StAR) mutations are the most frequent aetiologies of congenital lipoid adrenal hyperplasia (CLAH). Phenotypes may vary, and puberty may be absent in affected individuals. To date, only two pregnancies have been described in 46,XX CLAH patients with StAR mutations; these patients exhibited ovarian steroidogenesis along with spontaneous puberty and menarche and normal menses. The patient described here presented with CLAH caused by the homozygous (unreported, 1 bp) deletion c.719del in the StAR gene, which was diagnosed after acute adrenal insufficiency when the patient was 10 days old. The patient did not undergo spontaneous puberty, so puberty was induced by HRT when the patient was 13 years old. At the age of 25 years, the patient was referred to our reproductive unit because she desired to conceive. An initial cycle of clomiphene, stimulation produced follicular growth with two mature follicles measuring 18 and 15 mm, respectively, but the plasma oestradiol levels remained low (18 pg/ml) and the endometrium was thin (3 mm). Pregnancy was finally achieved after ovarian stimulation, IVF and transfer of frozen-thawed embryos after endometrial preparation with HRT. A normal female child was delivered following a 40 weeks' uneventful pregnancy. We therefore report the first IVF pregnancy achieved in a 46,XX CLAH patient homozygous for a StAR mutation, with inadequate ovarian steroidogenesis and no spontaneous puberty. PMID- 27698076 TI - Stillbirth: the impact of antiphospholipid syndrome? AB - Fetal death resulting in stillbirth is generally acknowledged as a feature of antiphospholipid syndrome. Recently published studies appear to confirm the association between antiphospholipid antibodies (aPL) and stillbirth, though additional studies of better design would be welcome. Emerging evidence suggests that treatment with heparin agents and low dose aspirin to prevent fetal death is imperfect. New therapeutic approaches for patients with lupus anticoagulant or triple aPL positivity are needed. PMID- 27698078 TI - Ivabradine: Do the Benefits Outweigh the Risks? AB - Ivabradine is a selective I f current inhibitor that is used to lower the heart rate (HR) of patients with angina and/or heart failure. It is approved for use in several countries, including the United Kingdom, Australia, Saudi Arabia, and the United States. The drug was studied in several clinical trials, and it exhibited beneficial effects on the approved indicators. However, there are some concerns with the safety profile of this drug, especially its effect in reducing HR and causing severe bradycardia. Therefore, the current review assessed the benefit risk balance of ivabradine. A literature review of the major published studies that assessed the efficacy and safety of ivabradine was performed. The online VigiBase adverse drug reaction (ADR) reporting system was also accessed to investigate reports associated with this drug. A full benefit-risk assessment was performed using the collected data from the above-mentioned resources. Most of the reviewed studies concluded that ivabradine exerted beneficial effects with a tolerable safety profile. Specifically, a favorable benefit-risk profile was found when ivabradine was used for patients with an HR >=70 beats per minute. Reports revealed that the most common ADR was bradycardia, which was expected. Other safety risks or ADRs were comparable to other prescribed drugs. This review presents an up-to-date analysis of ivabradine from the latest literature and reports. These studies suggest that ivabradine exhibits an acceptable and favorable benefit-risk profile, and this drug should be considered as a viable option in patients with angina pectoris and chronic heart failure. PMID- 27698077 TI - Src Family Kinases Are Regulated in Multiple Myeloma Cells by Phosphatase of Regenerating Liver-3. AB - : Phosphatase of regenerating liver-3 (PTP4A3/PRL-3) is a dual-specificity phosphatase that is upregulated in various types of cancers and is related to poor prognosis and aggressive tumor behavior. The expression level of PRL-3 is elevated in response to several antiapoptotic cytokines, including IL6, in cancer cells from patients with multiple myeloma (MM) and can promote survival and migration. Here, it is demonstrated that PRL-3 activates Src kinase in the IL6 dependent MM cell line INA-6. Inhibition of PRL-3 by a small-molecule inhibitor of PRL-3 or by shRNA resulted in inactivation of Src. In addition to activation of Src, PRL-3 also activated the Src family kinase (SFK) members LYN and HCK in INA-6 cells. Forced expression of catalytically inactive mutant PRL-3 decreased the activation of these three SFK members while the total level of HCK and FYN remained elevated. Inhibitors of Src increased sensitivity of cells overexpressing PRL-3 to the PRL-3 inhibitor through joint downregulation of both PRL-3 and Mcl-1. In conclusion, PRL-3 protected MM cells against apoptosis by dysregulating both the total levels and the activation levels of specific SFK members that are important for IL6 signal transduction in MM cells. Eventually, this led to increased levels of Mcl-1. IMPLICATIONS: This study suggests PRL-3 and SFKs are key mediators of the IL6-driven signaling events and points to both PRL-3 and SFK members as potential targets for treatment of MM.

AB - BACKGROUND: Patients hospitalized for first acute coronary syndrome (ACS) are frequently discharged on multiple new medications. The short-term tolerability of these medications is unknown. METHODS: This single-center cohort study assessed 30-day health-care utilization and how it may be impacted by medication prescribing trends. We included Olmsted County patients presenting with ACS and previously undiagnosed coronary artery disease in 2008 to 2009. All health-care contacts were reviewed 30 days after index hospital discharge for potential adverse medication effects including documented hypotension or bradycardia, or symptoms likely attributed to the medications. RESULTS: The study included 86 patients; their mean age was 63 (standard deviation: 15.5 years). Antianginal or antihypertensive cardiovascular (CV) medications were prescribed to 98% of patients at discharge; 76% were prescribed 2 or more. There were 233 health-care contacts in 30 days; 90 (39%) of these contacts were unscheduled. More CV medications tended to be prescribed to patients with unscheduled contacts, both pre-ACS ( P = .045) and upon hospital discharge ( P = .051). Hypotension and/or bradycardia at follow-up occurred in 52 patients (60%). Surprisingly, there was no association between hypotension and/or bradycardia at follow-up and increased health-care utilization ( P = .12). Potential adverse drug effects were reported in 34 (40%) patients. These patients had significantly more total health-care contacts ( P < .001) and unscheduled health-care contacts (median 0 vs 1.5; P < .001). CONCLUSIONS: Symptoms of adverse drug effects were associated with more frequent health-care utilization after ACS. Clinicians need to consider this while striving to increase patient compliance with post-ACS medications and optimize care transitions. PMID- 27698080 TI - Tyrosine Kinase Receptor Expression in Canine Liposarcoma. AB - The expression of tyrosine kinase receptors is attracting major interest in human and veterinary oncological pathology because of their role as targets for adjuvant therapies. Little is known about tyrosine kinase receptor (TKR) expression in canine liposarcoma (LP), a soft tissue sarcoma. The aim of this study was to evaluate the immunohistochemical expression of the TKRs fibroblast growth factor receptor 1 (FGFR1) and platelet-derived growth factor receptor-beta (PDGFRbeta); their ligands, fibroblast growth factor 2 (FGF2) and platelet derived growth factor B (PDGFB); and c-kit in canine LP. Immunohistochemical labeling was categorized as high or low expression and compared with the mitotic count and MIB-1-based proliferation index. Fifty canine LPs were examined, classified, and graded. Fourteen cases were classified as well differentiated, 7 as myxoid, 25 as pleomorphic, and 4 as dedifferentiated. Seventeen cases were grade 1, 26 were grade 2, and 7 were grade 3. A high expression of FGF2, FGFR1, PDGFB, and PDGFRbeta was identified in 62% (31/50), 68% (34/50), 81.6% (40/49), and 70.8% (34/48) of the cases, respectively. c-kit was expressed in 12.5% (6/48) of the cases. Mitotic count negatively correlated with FGF2 ( R = -0.41; P < .01), being lower in cases with high FGF2 expression, and positively correlated with PDGFRbeta ( R = 0.33; P < .01), being higher in cases with high PDGFRbeta expression. No other statistically significant correlations were identified. These results suggest that the PDGFRbeta-mediated pathway may have a role in the progression of canine LP and may thus represent a promising target for adjuvant cancer therapies. PMID- 27698081 TI - The Small RNA GcvB Promotes Mutagenic Break Repair by Opposing the Membrane Stress Response. AB - : Microbes and human cells possess mechanisms of mutagenesis activated by stress responses. Stress-inducible mutagenesis mechanisms may provide important models for mutagenesis that drives host-pathogen interactions, antibiotic resistance, and possibly much of evolution generally. In Escherichia coli, repair of DNA double-strand breaks is switched to a mutagenic mode, using error-prone DNA polymerases, via the SOS DNA damage and general (sigmaS) stress responses. We investigated small RNA (sRNA) clients of Hfq, an RNA chaperone that promotes mutagenic break repair (MBR), and found that GcvB promotes MBR by allowing a robust sigmaS response, achieved via opposing the membrane stress (sigmaE) response. Cells that lack gcvB were MBR deficient and displayed reduced sigmaS dependent transcription but not reduced sigmaS protein levels. The defects in MBR and sigmaS-dependent transcription in DeltagcvB cells were alleviated by artificially increasing sigmaS levels, implying that GcvB promotes mutagenesis by allowing a normal sigmaS response. DeltagcvB cells were highly induced for the sigmaE response, and blocking sigmaE response induction restored both mutagenesis and sigmaS-promoted transcription. We suggest that GcvB may promote the sigmaS response and mutagenesis indirectly, by promoting membrane integrity, which keeps sigmaE levels lower. At high levels, sigmaE might outcompete sigmaS for binding RNA polymerase and so reduce the sigmaS response and mutagenesis. The data show the delicate balance of stress response modulation of mutagenesis. IMPORTANCE: Mutagenesis mechanisms upregulated by stress responses promote de novo antibiotic resistance and cross-resistance in bacteria, antifungal drug resistance in yeasts, and genome instability in cancer cells under hypoxic stress. This paper describes the role of a small RNA (sRNA) in promoting a stress-inducible mutagenesis mechanism, mutagenic DNA break repair in Escherichia coli The roles of many sRNAs in E. coli remain unknown. This study shows that DeltagcvB cells, which lack the GcvB sRNA, display a hyperactivated membrane stress response and reduced general stress response, possibly because of sigma factor competition for RNA polymerase. This results in a mutagenic break repair defect. The data illuminate a function of GcvB sRNA in opposing the membrane stress response, and thus indirectly upregulating mutagenesis. PMID- 27698082 TI - The Phosphorolytic Exoribonucleases Polynucleotide Phosphorylase and RNase PH Stabilize sRNAs and Facilitate Regulation of Their mRNA Targets. AB - : Gene regulation by base pairing between small noncoding RNAs (sRNAs) and their mRNA targets is an important mechanism that allows bacteria to maintain homeostasis and respond to dynamic environments. In Gram-negative bacteria, sRNA pairing and regulation are mediated by several RNA-binding proteins, including the sRNA chaperone Hfq and polynucleotide phosphorylase (PNPase). PNPase and its homolog RNase PH together represent the two 3' to 5' phosphorolytic exoribonucleases found in Escherichia coli; however, the role of RNase PH in sRNA regulation has not yet been explored and reported. Here, we have examined in detail how PNPase and RNase PH interact to support sRNA stability, activity, and base pairing in exponential and stationary growth conditions. Our results indicate that these proteins facilitate the stability and regulatory function of the sRNAs RyhB, CyaR, and MicA during exponential growth. PNPase further appears to contribute to pairing between RyhB and its mRNA targets. During stationary growth, each sRNA responded differently to the absence or presence of PNPase and RNase PH. Finally, our results suggest that PNPase and RNase PH stabilize only Hfq-bound sRNAs. Taken together, these results confirm and extend previous findings that PNPase participates in sRNA regulation and reveal that RNase PH serves a similar, albeit more limited, role as well. These proteins may, therefore, act to protect sRNAs from spurious degradation while also facilitating regulatory pairing with their targets. IMPORTANCE: In many bacteria, Hfq dependent base-pairing sRNAs facilitate rapid changes in gene expression that are critical for maintaining homeostasis and responding to stress and environmental changes. While a role for Hfq in this process was identified more than 2 decades ago, the identity and function of the other proteins required for Hfq-dependent regulation by sRNAs have not been resolved. Here, we demonstrate that PNPase and RNase PH, the two phosphorolytic RNases in E. coli, stabilize sRNAs against premature degradation and, in the case of PNPase, also accelerate regulation by sRNA-mRNA pairings for certain sRNAs. These findings are the first to demonstrate that RNase PH influences and supports sRNA regulation and suggest shared and distinct roles for these phosphorolytic RNases in this process. PMID- 27698083 TI - The Catabolite Repressor Protein-Cyclic AMP Complex Regulates csgD and Biofilm Formation in Uropathogenic Escherichia coli. AB - The extracellular matrix protects Escherichia coli from immune cells, oxidative stress, predation, and other environmental stresses. Production of the E. coli extracellular matrix is regulated by transcription factors that are tuned to environmental conditions. The biofilm master regulator protein CsgD upregulates curli and cellulose, the two major polymers in the extracellular matrix of uropathogenic E. coli (UPEC) biofilms. We found that cyclic AMP (cAMP) regulates curli, cellulose, and UPEC biofilms through csgD The alarmone cAMP is produced by adenylate cyclase (CyaA), and deletion of cyaA resulted in reduced extracellular matrix production and biofilm formation. The catabolite repressor protein (CRP) positively regulated csgD transcription, leading to curli and cellulose production in the UPEC isolate, UTI89. Glucose, a known inhibitor of CyaA activity, blocked extracellular matrix formation when added to the growth medium. The mutant strains DeltacyaA and Deltacrp did not produce rugose biofilms, pellicles, curli, cellulose, or CsgD. Three putative CRP binding sites were identified within the csgD-csgB intergenic region, and purified CRP could gel shift the csgD-csgB intergenic region. Additionally, we found that CRP binded upstream of kpsMT, which encodes machinery for K1 capsule production. Together our work shows that cAMP and CRP influence E. coli biofilms through transcriptional regulation of csgD IMPORTANCE The catabolite repressor protein (CRP)-cyclic AMP (cAMP) complex influences the transcription of ~7% of genes on the Escherichia coli chromosome (D. Zheng, C. Constantinidou, J. L. Hobman, and S. D. Minchin, Nucleic Acids Res 32:5874-5893, 2004, https://dx.doi.org/10.1093/nar/gkh908). Glucose inhibits E. coli biofilm formation, and DeltacyaA and Deltacrp mutants show impaired biofilm formation (D. W. Jackson, J.W. Simecka, and T. Romeo, J Bacteriol 184:3406-3410, 2002, https://dx.doi.org/10.1128/JB.184.12.3406-3410.2002). We determined that the cAMP CRP complex regulates curli and cellulose production and the formation of rugose and pellicle biofilms through csgD Additionally, we propose that cAMP may work as a signaling compound for uropathogenic E. coli (UPEC) to transition from the bladder lumen to inside epithelial cells for intracellular bacterial community formation through K1 capsule regulation. PMID- 27698084 TI - Aag Hypoxanthine-DNA Glycosylase Is Synthesized in the Forespore Compartment and Involved in Counteracting the Genotoxic and Mutagenic Effects of Hypoxanthine and Alkylated Bases in DNA during Bacillus subtilis Sporulation. AB - : Aag from Bacillus subtilis has been implicated in in vitro removal of hypoxanthine and alkylated bases from DNA. The regulation of expression of aag in B. subtilis and the resistance to genotoxic agents and mutagenic properties of an Aag-deficient strain were studied here. A strain with a transcriptional aag-lacZ fusion expressed low levels of beta-galactosidase during growth and early sporulation but exhibited increased transcription during late stages of this developmental process. Notably, aag-lacZ expression was higher inside the forespore than in the mother cell compartment, and this expression was abolished in a sigG-deficient background, suggesting a forespore-specific mechanism of aag transcription. Two additional findings supported this suggestion: (i) expression of an aag-yfp fusion was observed in the forespore, and (ii) in vivo mapping of the aag transcription start site revealed the existence of upstream regulatory sequences possessing homology to sigmaG-dependent promoters. In comparison with the wild-type strain, disruption of aag significantly reduced survival of sporulating B. subtilis cells following nitrous acid or methyl methanesulfonate treatments, and the Rifr mutation frequency was significantly increased in an aag strain. These results suggest that Aag protects the genome of developing B. subtilis sporangia from the cytotoxic and genotoxic effects of base deamination and alkylation. IMPORTANCE: In this study, evidence is presented revealing that aag, encoding a DNA glycosylase implicated in processing of hypoxanthine and alkylated DNA bases, exhibits a forespore-specific pattern of gene expression during B. subtilis sporulation. Consistent with this spatiotemporal mode of expression, Aag was found to protect the sporulating cells of this microorganism from the noxious and mutagenic effects of base deamination and alkylation. PMID- 27698085 TI - Intracellular d-Serine Accumulation Promotes Genetic Diversity via Modulated Induction of RecA in Enterohemorrhagic Escherichia coli. AB - : We recently discovered that exposure of enterohemorrhagic Escherichia coli (EHEC) to d-serine resulted in accumulation of this unusual amino acid, induction of the SOS regulon, and downregulation of the type III secretion system that is essential for efficient colonization of the host. Here, we have investigated the physiological relevance of this elevated SOS response, which is of particular interest given the presence of Stx toxin-carrying lysogenic prophages on the EHEC chromosome that are activated during the SOS response. We found that RecA elevation in response to d-serine, while being significant, was heterogeneous and not capable of activating stx expression or stx phage transduction to a nonlysogenic recipient. This "SOS-like response" was, however, capable of increasing the mutation frequency associated with low-level RecA activity, thus promoting genetic diversity. Furthermore, this response was entirely dependent on RecA and enhanced in the presence of a DNA-damaging agent, indicating a functional SOS response, but did not result in observable cleavage of the LexA repressor alone, indicating a controlled mechanism of induction. This work demonstrates that environmental factors not usually associated with DNA damage are capable of promoting an SOS-like response. We propose that this modulated induction of RecA allows EHEC to adapt to environmental insults such as d-serine while avoiding unwanted phage-induced lysis. IMPORTANCE: The SOS response is a global stress network that is triggered by the presence of DNA damage due to breakage or stalled replication forks. Activation of the SOS response can trigger the replication of lytic bacteriophages and promote genetic diversification through error-prone polymerases. We have demonstrated that the host-associated metabolite d-serine contributes to Escherichia coli niche specification and accumulates inside cells that cannot catabolize it. This results in a modulated activation of the SOS antirepressor RecA that is insufficient to trigger lytic bacteriophage but capable of increasing the SOS-associated mutation frequency. These findings describe how relevant signals not normally associated with DNA damage can hijack the SOS response, promoting diversity as E. coli strains adapt while avoiding unwanted phage lysis. PMID- 27698086 TI - Identification of Functions Affecting Predator-Prey Interactions between Myxococcus xanthus and Bacillus subtilis. AB - : Soil bacteria engage each other in competitive and cooperative ways to determine their microenvironments. In this study, we report the identification of a large number of genes required for Myxococcus xanthus to engage Bacillus subtilis in a predator-prey relationship. We generated and tested over 6,000 individual transposon insertion mutants of M. xanthus and found many new factors required to promote efficient predation, including the specialized metabolite myxoprincomide, an ATP-binding cassette (ABC) transporter permease, and a clustered regularly interspaced short palindromic repeat (CRISPR) locus encoding bacterial immunity. We also identified genes known to be involved in predation, including those required for the production of exopolysaccharides and type IV pilus (T4P)-dependent motility, as well as chemosensory and two-component systems. Furthermore, deletion of these genes confirmed their role during predation. Overall, M. xanthus predation appears to be a multifactorial process, with multiple determinants enhancing predation capacity. IMPORTANCE: Soil bacteria engage each other in complex environments and utilize multiple traits to ensure survival. Here, we report the identification of multiple traits that enable a common soil organism, Myxococcus xanthus, to prey upon and utilize nutrients from another common soil organism, Bacillus subtilis We mutagenized the predator and carried out a screen to identify genes that were required to either enhance or diminish capacity to consume prey. We identified dozens of genes encoding factors that contribute to the overall repertoire for the predator to successfully engage its prey in the natural environment. PMID- 27698089 TI - The Utility of Assessing Neck Acne. AB - BACKGROUND: Acne grading is an essential component in establishing treatment options, but little is known on how neck acne should be incorporated into grading scales. OBJECTIVE: Our objective was to explore the prevalence of neck acne and determine if its own severity category on an acne global grading scale was warranted. METHODS: Acne severity was assessed in 6 categories: face, chest, back, anterior upper (AUN), anterior lower neck (ALN), and posterior neck (PN). RESULTS: The overall prevalence of neck acne was 49%. Of these, 44% had AUN acne, 18.5% had ALN acne, and 19.8% had PN acne. AUN and facial acne had a significant correlation ( r = 0.37, P < .05). No correlation was seen amongst other areas. Males presented with a significantly higher severity of AUN (mean [SD], 1.37 [1.09]) than females (mean [SD], 0.52 [0.91]), on average. CONCLUSIONS: While neck acne has proven to be common amongst those with acne on other areas of the body, facial acne can be used as a proxy for classification, as neck severity is usually milder. PMID- 27698088 TI - Interactions between the Cytoplasmic Domains of PspB and PspC Silence the Yersinia enterocolitica Phage Shock Protein Response. AB - : The phage shock protein (Psp) system is a widely conserved cell envelope stress response that is essential for the virulence of some bacteria, including Yersinia enterocolitica Recruitment of PspA by the inner membrane PspB-PspC complex characterizes the activated state of this response. The PspB-PspC complex has been proposed to be a stress-responsive switch, changing from an OFF to an ON state in response to an inducing stimulus. In the OFF state, PspA cannot access its binding site in the C-terminal cytoplasmic domain of PspC (PspCCT), because this site is bound to PspB. PspC has another cytoplasmic domain at its N-terminal end (PspCNT), which has been thought to play a role in maintaining the OFF state, because its removal causes constitutive activation. However, until now, this role has proved recalcitrant to experimental investigation. Here, we developed a combination of approaches to investigate the role of PspCNT in Y. enterocolitica Pulldown assays provided evidence that PspCNT mediates the interaction of PspC with the C-terminal cytoplasmic domain of PspB (PspBCT) in vitro Furthermore, site-specific oxidative cross-linking suggested that a PspCNT-PspBCT interaction occurs only under noninducing conditions in vivo Additional experiments indicated that mutations in pspC might cause constitutive activation by compromising this PspCNT binding site or by causing a conformational disturbance that repositions PspCNT in vivo These findings have provided the first insight into the regulatory function of the N-terminal cytoplasmic domain of PspC, revealing that its ability to participate in an inhibitory complex is essential to silencing the Psp response. IMPORTANCE: The phage shock protein (Psp) response has generated widespread interest because it is linked to important phenotypes, including antibiotic resistance, biofilm formation, and virulence in a diverse group of bacteria. Therefore, achieving a comprehensive understanding of how this response is controlled at the molecular level has obvious significance. An integral inner membrane protein complex is believed to be a critical regulatory component that acts as a stress-responsive switch, but some essential characteristics of the switch states are poorly understood. This study provides an important advance by uncovering a new protein interaction domain within this membrane protein complex that is essential to silencing the Psp response in the absence of an inducing stimulus. PMID- 27698090 TI - An Emerging Risk Factor of Sexual Abuse: The Use of Smartphone Dating Applications. AB - Smartphone dating applications (apps) have become popular in recent years. However, the association between the use of dating apps and sexual abuse remains uninvestigated. The aim of this study was to examine the association between using dating apps and the sexual abuse of males and females. Six hundred sixty six participants were recruited in four universities in Hong Kong in 2015. Overall, the 1-year prevalence of sexual abuse was 12.4% (95% confidence interval [CI]: [9.8, 14.9]) and the lifetime prevalence was 14.2% (95% CI: [11.5, 16.9]). Multiple logistic regressions found that users of dating apps (adjusted odds ratio [aOR]: 2.13, p < .05) were more likely to be sexually abused in the past year than non-users. Using dating apps was also a risk factor of lifetime sexual abuse (aOR: 1.83, p < .05). Our findings suggest that app users should deserve more attention in risk assessment, risk stratification, and sexual abuse prevention programs. PMID- 27698087 TI - Autonomous Replication of the Conjugative Transposon Tn916. AB - : Integrative and conjugative elements (ICEs), also known as conjugative transposons, are self-transferable elements that are widely distributed among bacterial phyla and are important drivers of horizontal gene transfer. Many ICEs carry genes that confer antibiotic resistances to their host cells and are involved in the dissemination of these resistance genes. ICEs reside in host chromosomes but under certain conditions can excise to form a plasmid that is typically the substrate for transfer. A few ICEs are known to undergo autonomous replication following activation. However, it is not clear if autonomous replication is a general property of many ICEs. We found that Tn916, the first conjugative transposon identified, replicates autonomously via a rolling-circle mechanism. Replication of Tn916 was dependent on the relaxase encoded by orf20 of Tn916 The origin of transfer of Tn916, oriT(916), also functioned as an origin of replication. Using immunoprecipitation and mass spectrometry, we found that the relaxase (Orf20) and the two putative helicase processivity factors (Orf22 and Orf23) encoded by Tn916 likely interact in a complex and that the Tn916 relaxase contains a previously unidentified conserved helix-turn-helix domain in its N terminal region that is required for relaxase function and replication. Lastly, we identified a functional single-strand origin of replication (sso) in Tn916 that we predict primes second-strand synthesis during rolling-circle replication. Together these results add to the emerging data that show that several ICEs replicate via a conserved, rolling-circle mechanism. IMPORTANCE: Integrative and conjugative elements (ICEs) drive horizontal gene transfer and the spread of antibiotic resistances in bacteria. ICEs reside integrated in a host genome but can excise to create a plasmid that is the substrate for transfer to other cells. Here we show that Tn916, an ICE with broad host range, undergoes autonomous rolling-circle replication when in the plasmid form. We found that the origin of transfer functions as a double-stranded origin of replication and identified a single-stranded origin of replication. It was long thought that ICEs do not undergo autonomous replication. Our work adds to the evidence that ICEs replicate autonomously as part of their normal life cycle and indicates that diverse ICEs use the same replicative mechanism. PMID- 27698091 TI - Social Class and the Motivational Relevance of Other Human Beings: Evidence From Visual Attention. AB - We theorize that people's social class affects their appraisals of others' motivational relevance-the degree to which others are seen as potentially rewarding, threatening, or otherwise worth attending to. Supporting this account, three studies indicate that social classes differ in the amount of attention their members direct toward other human beings. In Study 1, wearable technology was used to film the visual fields of pedestrians on city streets; higher-class participants looked less at other people than did lower-class participants. In Studies 2a and 2b, participants' eye movements were tracked while they viewed street scenes; higher class was associated with reduced attention to people in the images. In Study 3, a change-detection procedure assessed the degree to which human faces spontaneously attract visual attention; faces proved less effective at drawing the attention of high-class than low-class participants, which implies that class affects spontaneous relevance appraisals. The measurement and conceptualization of social class are discussed. PMID- 27698092 TI - "It's Easy to Get Fags": A Qualitative Study of Disadvantaged Young People's Perspectives on Cigarette Availability and Access. AB - Introduction: Reducing young people's access to cigarettes is a key element of smoking prevention policies. This article explores how young people source cigarettes following the increase in the UK minimum age of sale from 16 to 18 years. Methods: Semi-structured individual, paired and triadic interviews with 60 disadvantaged young people aged between 12 and 17. Participants were recruited from clubs and voluntary organizations offering advice and support to disadvantaged young people. Results: Most participants said they sourced cigarettes from shops, but understandings of "buying cigarettes from shops" included using intermediaries for proxy purchases. Access from social sources was contingent on reciprocation, and blackmarket sources were avoided. The distinction between potential and actual sources reflected participants concerns about their presentation of self. Those who bought cigarettes directly from shops accrued status and power in negotiating social hierarchies. Participants therefore highlighted their smoking related competencies, that is, ability to secure regular retail access to tobacco, while downplaying the significant difficulties they experienced. Conclusions: The presentational dimension of youth cigarette access highlights a need for caution in associating self-reported changes in young people's cigarette sources straightforwardly with access policies. The conflation of direct retail purchases with proxy purchases, and the interrelationship between commercial and social cigarette sources also raises issues for interpreting data on "usual" cigarette sources from national surveys. Findings suggest that some young people may still be both reliant on making retail cigarette purchases following the increase in the age of sale in the United Kingdom, and experiencing significant difficulties making these. Implications: This study highlights the self-presentational dimension of youth cigarette access in a particular community context, and the important distinction between the apparent range of sources available and their social acceptability in young people's social networks. Young smokers tended to conflate direct retail purchases with proxy purchases, raising issues for interpreting survey data on "usual" cigarette source. The presentational dimension of youth cigarette access also highlights a need for caution in associating self-reported changes in young people's cigarette sources with access policies. Despite participants' stated easy access, few were able to buy cigarettes directly, underscoring the effectiveness of youth access policies. PMID- 27698094 TI - Comparison of the Fagerstrom Test for Cigarette Dependence and the Heaviness of Smoking Index in the Second and Third Trimester of Pregnancy. AB - Introduction: Smoking cessation at any stage of pregnancy can benefit the mother and fetus. Cigarette dependence is a significant factor in women who continue to smoke during pregnancy and accurate assessment of cigarette dependence can be helpful in planning smoking cessation programs. The objective of our study was to investigate the validity of the Fagerstrom Test for Cigarette Dependence (FTCD) and Heaviness of Smoking Index (HSI) as measures of cigarette dependence in the second and third trimesters of pregnancy by comparing them to serum cotinine levels. Methods: Prospective cohort study of 167 women in their second and third trimester of pregnancy who self-reported cigarette smoking. They were administered the FTCD questionnaire and blood was drawn for cotinine measurements using a direct enzyme linked immunoassay. Linear regression was used to adjust for maternal age, body mass index, gestation, and parity to investigate the association between cotinine levels and the two scores. Results: Both the FTCD and HSI correlated significantly with serum cotinine levels (Spearman coefficient 0.42 and 0.37, respectively, p < .001). The correlation coefficients of both scores were higher in primigravidas (n = 51) compared to multigravidas, but the difference was statistically nonsignificant. Using multiple linear regression, both scores were significantly related to serum cotinine levels. For each unit increase in the FTCD and HSI, the serum cotinine level increased by 21.4 ng/mL (95% confidence interval 10.1-32.7, p <0.001) and 37 ng/mL (95% confidence interval 18.6-55.4, p < 0.001), respectively. Conclusions: Both the FTCD and HSI can be used to assess cigarette dependence in the second and third trimester of pregnancy. Implications: There is lack of data on the validity of the FTCD and the HSI as markers of cigarette dependence during the second and third trimester of pregnancy. Our study suggests that both the FTCD and HSI perform well in assessing cigarette dependence in the second and third trimester of pregnancy and can be used to plan smoking cessation programs. PMID- 27698093 TI - A Qualitative Study Among Mexican Americans to Understand Factors Influencing the Adoption and Enforcement of Home Smoking Bans. AB - Introduction: One-third of Mexican-American children, in addition to nonsmoker adults, are exposed to secondhand smoke at home, yet few interventions target Mexican-American households. An effective, brief English language program, tested with United Way 2-1-1 callers in Atlanta, increased home smoking bans (confirmed by air monitors). Two randomized controlled trials in North Carolina and Texas replicated those results. We explored factors determining adoption and enforcement of smoking bans in Mexican-American households to inform program linguistic and cultural adaptation to broaden program reach and relevance. Methods: Bilingual interviewers recruited convenience samples of Mexican-American smokers and nonsmokers living with at least one smoker in Houston and San Diego households and asked open-ended questions regarding conditions for implementing home and vehicle smoking bans and conditions for varying acceptance of bans. Investigators independently reviewed English transcripts and completed a descriptive analysis using ATLAS.ti. Results: Participants (n = 43) were predominantly female (n = 31), current smokers (n = 26), interviewed in Spanish (n = 26), had annual household incomes less than $30000 (n = 24), and allowed smoking inside the home (n = 24). Themes related to difficulty creating and enforcing bans included courtesy, respect for guests and heads of household who smoke, and gender imbalances in decision making. Participants viewed protecting children's health as a reason for the ban but not protecting adult nonsmokers' health. Conclusion: A dual-language, culturally adapted intervention targeting multigenerational Mexican-American households should address household differences regarding language and consider influences of cultural values on family dynamics and interactions with guests that may weaken bans. Implications: Qualitative interviews suggested cultural and family considerations to address in adapting a brief evidence-based smoke-free homes intervention for Mexican Americans, including traditional gender roles, unique contexts of multigenerational households, and language preferences. Our work confirms previous research among Latinos regarding importance of common cultural constructs, such as respeto (deference), simpatia (courtesy and agreeability), and familismo (family attachment), which inform behaviors that may impede or facilitate adopting and enforcing home smoking bans. Decision-making gender imbalances, high regard for head-of-household and guest smokers, and less sensitivity to the health of nonsmoker adults compared with children may lead to permission to smoke indoors.

Their findings have important and immediate clinical implications as the resistance mutations detected impart differential sensitivities to available ALK inhibitors, thereby highlighting the need for sequential biopsies with molecular testing to determine the most effective treatment strategy upon disease progression.

PMID- 27698102 TI - Women's Health and Mindfulness (WHAM): A Randomized Intervention Among Older Lesbian/Bisexual Women. AB - INTRODUCTION: Lesbian and bisexual (LB) women have higher body weight than heterosexual women. Interventions focused on health and well-being versus weight loss may be more likely to succeed among LB women. This article describes effects of Women's Health and Mindfulness, a 12-week pilot intervention addressing mindfulness, healthy eating, and physical activity, on outcomes associated with chronic disease risk among overweight and obese LB women older than 40 years. METHOD: Eighty women were randomized, using a stepped-wedge design, to either an immediate- or a delayed-start intervention group; the delayed-start group served as the control. Eligible participants were aged 40 years or older, identified as LB, and had a body mass index of 27 or greater. We compared differences in biological markers of chronic disease, mindfulness, nutrition, and physical activity between immediate- and delayed-start intervention groups. RESULTS: We observed clinically significant improvements in low-density lipoprotein cholesterol but no change in hemoglobin A1c. We found evidence of intervention effects on improved mindfulness and mindful eating scores and on nutrition (improved vegetable intake). CONCLUSIONS: The Women's Health and Mindfulness pilot intervention appears to have initiated positive behavioral and physical health changes in this population. Refinements to the intervention model, such as extended intervention duration, and longer term follow-up are warranted to determine sustained effects.

PMID- 27698105 TI - The Role of High-resolution Peripheral Quantitative Computed Tomography as a Biomarker for Joint Damage in Inflammatory Arthritis. AB - Since 2011, members of the SPECTRA Collaboration (Study grouP for xtrEme-Computed Tomography in Rheumatoid Arthritis) have investigated the validity, reliability, and responsiveness of high-resolution peripheral quantitative computed tomography (HR-pQCT) as a biomarker for joint damage in inflammatory arthritis. Presented in this series of articles are a systematic review of HR-pQCT-related findings to date, a review of selected images of cortical and subchondral trabecular bone of metacarpophalangeal (MCP) joints, results of a consensus process to standardize the definition of erosions and their quantification, as well as an examination of the effect of joint flexion on width and volume assessment of the joint space. PMID- 27698106 TI - Heterogeneity of Cortical Breaks in Hand Joints of Patients with Rheumatoid Arthritis and Healthy Controls Imaged by High-resolution Peripheral Quantitative Computed Tomography. AB - OBJECTIVE: Conventional radiographs (CR) of the hands are the gold standard for imaging bone erosions. The presence of bone erosions, reflected by the presence of cortical breaks, is a poor prognostic factor in patients with rheumatoid arthritis (RA). The availability of high-resolution peripheral quantitative computed tomography (HR-pQCT) enables detailed investigation of cortical breaks in rheumatic diseases. The aim of this image review is to show HR-pQCT images of the spectrum of cortical breaks with and without underlying trabecular bone changes in metacarpophalangeal (MCP) joints of healthy controls (HC) and patients with RA, with corresponding images on CR and magnetic resonance imaging (MRI). METHODS: Second and third MCP joints of 41 patients (of which 10 were early RA with <= 2 years and 24 longstanding RA with >= 10 years of disease duration) and 38 HC were imaged by CR, MRI, and HR-pQCT (XtremeCT1, Scanco Medical AG). Representative images of the spectrum of cortical breaks were selected. RESULTS: Cortical breaks were found in early and longstanding RA, but also in HC. They were heterogeneous in size, location, and number per joint, with a variety of surrounding cortical and underlying trabecular bone characteristics. CONCLUSION: Using HR-pQCT images of MCP joints, heterogeneous cortical breaks with and without surrounding trabecular bone changes were found, not only in RA but also in HC. The underlying mechanisms and significance of this spectrum of cortical breaks as found with high 3-D resolution needs further investigation. PMID- 27698107 TI - High-resolution Peripheral Quantitative Computed Tomography Imaging in the Assessment of Periarticular Bone of Metacarpophalangeal and Wrist Joints. AB - OBJECTIVE: To synthesize descriptions of periarticular findings at the metacarpophalangeal (MCP) and wrist joints in different types of arthritis and in the normal state imaged by high-resolution peripheral quantitative computed tomography (HR-pQCT); to assemble the literature reporting on the ability of HR pQCT to detect findings relative to other imaging modalities; and to collate results on the reproducibility of image interpretation. METHODS: A systematic literature review was performed using terms for HR-pQCT and MCP or wrist joints using medical literature databases and conference abstracts. Any study describing predefined pathology findings, comparison to another radiographic technique, or a measure of reproducibility was included with no limitation by disease state. RESULTS: We identified 44 studies meeting inclusion criteria from the 1901 articles identified by our search. All 44 reported on pathology findings, including erosions (n = 31), bone microarchitecture (n = 10) and bone mineral density (n = 10) variables, joint space evaluation (n = 7), or osteophyte characterization (n = 7). Seventeen of the studies compared HR-pQCT findings to either plain radiography (n = 9), ultrasound (n = 4), magnetic resonance imaging (n = 5), or microcomputed tomography (n = 2), with HR-pQCT having high sensitivity for erosion detection. Twenty-four studies included an assessment of reproducibility with good to excellent metrics, and highlighting the critical importance of positioning when assessing joint space variables. CONCLUSION: Despite high sensitivity for erosion detection and good reproducibility, more research is required to determine where HR-pQCT can be applied to enhance our understanding of periarticular bone changes in a variety of arthritis conditions.

AB - OBJECTIVE: The position-dependence of a method to measure the joint space of metacarpophalangeal (MCP) joints using high-resolution peripheral quantitative computed tomography (HR-pQCT) was studied. METHODS: Cadaveric MCP were imaged at 7 flexion angles between 0 and 30 degrees. The variability in reproducibility for mean, minimum, and maximum joint space widths and volume measurements was calculated for increasing degrees of flexion. RESULTS: Root mean square coefficient of variance values were < 5% under 20 degrees of flexion for mean, maximum, and volumetric joint spaces. Values for minimum joint space width were optimized under 10 degrees of flexion. CONCLUSION: MCP joint space measurements should be acquired at < 10 degrees of flexion in longitudinal studies. PMID- 27698108 TI - Definition for Rheumatoid Arthritis Erosions Imaged with High Resolution Peripheral Quantitative Computed Tomography and Interreader Reliability for Detection and Measurement. AB - OBJECTIVE: High-resolution peripheral quantitative computed tomography (HR-pQCT) sensitively detects erosions in rheumatoid arthritis (RA); however, nonpathological cortical bone disruptions are potentially misclassified as erosive. Our objectives were to set and test a definition for pathologic cortical bone disruptions in RA and to standardize reference landmarks for measuring erosion size. METHODS: HR-pQCT images of metacarpophalangeal joints of RA and control subjects were used in an iterative process to achieve consensus on the definition and reference landmarks. Independent readers (n = 11) applied the definition to score 58 joints and measure pathologic erosions in 2 perpendicular multiplanar reformations for their maximum width and depth. Interreader reliability for erosion detection and variability in measurements between readers [root mean square coefficient of variation (RMSCV), intraclass correlation (ICC)] were calculated. RESULTS: Pathologic erosions were defined as cortical breaks extending over a minimum of 2 consecutive slices in perpendicular planes, with underlying trabecular bone loss and a nonlinear shape. Interreader agreement for classifying pathologic erosions was 90.2%, whereas variability for width and depth erosion assessment was observed (RMSCV perpendicular width 12.3%, axial width 20.6%, perpendicular depth 24.0%, axial depth 22.2%; ICC perpendicular width 0.206, axial width 0.665, axial depth 0.871, perpendicular depth 0.783). Mean erosion width was 1.84 mm (range 0.16-8.90) and mean depth was 1.86 mm (range 0.30-8.00). CONCLUSION: We propose a new definition for erosions visualized with HR-pQCT imaging. Interreader reliability for erosion detection is good, but further refinement of selection of landmarks for erosion size measurement, or automated volumetric methods, will be pursued.

PMID- 27698112 TI - Wnt/beta-catenin signaling promotes self-renewal and inhibits the primed state transition in naive human embryonic stem cells. AB - In both mice and humans, pluripotent stem cells (PSCs) exist in at least two distinct states of pluripotency, known as the naive and primed states. Our understanding of the intrinsic and extrinsic factors that enable PSCs to self renew and to transition between different pluripotent states is important for understanding early development. In mouse embryonic stem cells (mESCs), Wnt proteins stimulate mESC self-renewal and support the naive state. In human embryonic stem cells (hESCs), Wnt/beta-catenin signaling is active in naive-state hESCs and is reduced or absent in primed-state hESCs. However, the role of Wnt/beta-catenin signaling in naive hESCs remains largely unknown. Here, we demonstrate that inhibition of the secretion of Wnts or inhibition of the stabilization of beta-catenin in naive hESCs reduces cell proliferation and colony formation. Moreover, we show that addition of recombinant Wnt3a partially rescues cell proliferation in naive hESCs caused by inhibition of Wnt secretion. Notably, inhibition of Wnt/beta-catenin signaling in naive hESCs did not cause differentiation. Instead, it induced primed hESC-like proteomic and metabolic profiles. Thus, our results suggest that naive hESCs secrete Wnts that activate autocrine or paracrine Wnt/beta-catenin signaling to promote efficient self renewal and inhibit the transition to the primed state. PMID- 27698113 TI - Clonal expansion of CD8 T cells in the systemic circulation precedes development of ipilimumab-induced toxicities. AB - Immune checkpoint therapies, such as ipilimumab, induce dramatic antitumor responses in a subset of patients with advanced malignancies, but they may also induce inflammatory responses and toxicities termed immune-related adverse events (irAEs). These irAEs are often low grade and manageable, but severe irAEs may lead to prolonged hospitalizations or fatalities. Early intervention is necessary to minimize morbidities that occur with severe irAEs. However, correlative biomarkers are currently lacking. In a phase II clinical trial that treated 27 patients with metastatic prostate cancer, we aimed to test the safety and efficacy of androgen deprivation therapy plus ipilimumab. In this study, we observed grade 3 toxicities in >40% of treated patients, which led to early closure of the study. Because ipilimumab enhances T-cell responses, we hypothesized that increased clonal T-cell responses in the systemic circulation may contribute to irAEs. Sequencing of the T-cell receptor beta-chains in purified T cells revealed clonal expansion of CD8 T cells, which occurred in blood samples collected before the onset of grade 2-3 irAEs. These initial results suggested that expansion of >=55 CD8 T-cell clones preceded the development of severe irAEs. We further evaluated available blood samples from a second trial and determined that patients who experienced grade 2-3 irAEs also had expansion of >=55 CD8 T-cell clones in blood samples collected before the onset of irAEs. We propose that CD8 T-cell clonal expansion may be a correlative biomarker to enable close monitoring and early intervention for patients receiving ipilimumab. PMID- 27698116 TI - Equatorial heat accumulation as a long-term trigger of permanent Antarctic ice sheets during the Cenozoic. AB - Growth of the first permanent Antarctic ice sheets at the Eocene-Oligocene Transition (EOT), ~33.7 million years ago, indicates a major climate shift within long-term Cenozoic cooling. The driving mechanisms that set the stage for this glaciation event are not well constrained, however, owing to large uncertainties in temperature reconstructions during the Eocene, especially at lower latitudes. To address this deficiency, we used recent developments in coccolith biogeochemistry to reconstruct equatorial Atlantic sea surface temperature (SST) and atmospheric pCO2 values from pelagic sequences preceding and spanning the EOT. We found significantly more variability in equatorial SSTs than previously reported, with pronounced cooling from the Early to Middle Eocene and subsequent warming during the Late Eocene. Thus, we show that the Antarctic glaciation at the Eocene-Oligocene boundary was preceded by a period of heat accumulation in the low latitudes, likely focused in a progressively contracting South Atlantic gyre, which contributed to cooling high-latitude austral regions. This prominent redistribution of heat corresponds to the emplacement of a strong meridional temperature gradient that typifies icehouse climate conditions. Our equatorial coccolith-derived geochemical record thus highlights an important period of global climatic and oceanic upheaval, which began 4 million years before the EOT and, superimposed on a long-term pCO2 decline, drove the Earth system toward a glacial tipping point in the Cenozoic. PMID- 27698114 TI - eIF2alpha phosphorylation controls thermal nociception. AB - A response to environmental stress is critical to alleviate cellular injury and maintain cellular homeostasis. Eukaryotic initiation factor 2 (eIF2) is a key integrator of cellular stress responses and an important regulator of mRNA translation. Diverse stress signals lead to the phosphorylation of the alpha subunit of eIF2 (Ser51), resulting in inhibition of global protein synthesis while promoting expression of proteins that mediate cell adaptation to stress. Here we report that eIF2alpha is instrumental in the control of noxious heat sensation. Mice with decreased eIF2alpha phosphorylation (eIF2alpha+/S51A) exhibit reduced responses to noxious heat. Pharmacological attenuation of eIF2alpha phosphorylation decreases thermal, but not mechanical, pain sensitivity, whereas increasing eIF2alpha phosphorylation has the opposite effect on thermal nociception. The impact of eIF2alpha phosphorylation (p-eIF2alpha) on thermal thresholds is dependent on the transient receptor potential vanilloid 1. Moreover, we show that induction of eIF2alpha phosphorylation in primary sensory neurons in a chronic inflammation pain model contributes to thermal hypersensitivity. Our results demonstrate that the cellular stress response pathway, mediated via p-eIF2alpha, represents a mechanism that could be used to alleviate pathological heat sensation. PMID- 27698115 TI - An evolutionarily conserved element in initiator tRNAs prompts ultimate steps in ribosome maturation. AB - Ribosome biogenesis, a complex multistep process, results in correct folding of rRNAs, incorporation of >50 ribosomal proteins, and their maturation. Deficiencies in ribosome biogenesis may result in varied faults in translation of mRNAs causing cellular toxicities and ribosomopathies in higher organisms. How cells ensure quality control in ribosome biogenesis for the fidelity of its complex function remains unclear. Using Escherichia coli, we show that initiator tRNA (i-tRNA), specifically the evolutionarily conserved three consecutive GC base pairs in its anticodon stem, play a crucial role in ribosome maturation. Deficiencies in cellular contents of i-tRNA confer cold sensitivity and result in accumulation of ribosomes with immature 3' and 5' ends of the 16S rRNA. Overexpression of i-tRNA in various strains rescues biogenesis defects. Participation of i-tRNA in the first round of initiation complex formation licenses the final steps of ribosome maturation by signaling RNases to trim the terminal extensions of immature 16S rRNA. PMID- 27698117 TI - Regulation of MIR165/166 by class II and class III homeodomain leucine zipper proteins establishes leaf polarity. AB - A defining feature of plant leaves is their flattened shape. This shape depends on an antagonism between the genes that specify adaxial (top) and abaxial (bottom) tissue identity; however, the molecular nature of this antagonism remains poorly understood. Class III homeodomain leucine zipper (HD-ZIP) transcription factors are key mediators in the regulation of adaxial-abaxial patterning. Their expression is restricted adaxially during early development by the abaxially expressed microRNA (MIR)165/166, yet the mechanism that restricts MIR165/166 expression to abaxial leaf tissues remains unknown. Here, we show that class III and class II HD-ZIP proteins act together to repress MIR165/166 via a conserved cis-element in their promoters. Organ morphology and tissue patterning in plants, therefore, depend on a bidirectional repressive circuit involving a set of miRNAs and its targets. PMID- 27698119 TI - Estimates of the magnitudes of major marine mass extinctions in earth history. AB - Procedures introduced here make it possible, first, to show that background (piecemeal) extinction is recorded throughout geologic stages and substages (not all extinction has occurred suddenly at the ends of such intervals); second, to separate out background extinction from mass extinction for a major crisis in earth history; and third, to correct for clustering of extinctions when using the rarefaction method to estimate the percentage of species lost in a mass extinction. Also presented here is a method for estimating the magnitude of the Signor-Lipps effect, which is the incorrect assignment of extinctions that occurred during a crisis to an interval preceding the crisis because of the incompleteness of the fossil record. Estimates for the magnitudes of mass extinctions presented here are in most cases lower than those previously published. They indicate that only ~81% of marine species died out in the great terminal Permian crisis, whereas levels of 90-96% have frequently been quoted in the literature. Calculations of the latter numbers were incorrectly based on combined data for the Middle and Late Permian mass extinctions. About 90 orders and more than 220 families of marine animals survived the terminal Permian crisis, and they embodied an enormous amount of morphological, physiological, and ecological diversity. Life did not nearly disappear at the end of the Permian, as has often been claimed. PMID- 27698121 TI - Increasing vertical resolution in US models to improve track forecasts of Hurricane Joaquin with HWRF as an example. AB - The atmosphere-ocean coupled Hurricane Weather Research and Forecast model (HWRF) developed at the National Centers for Environmental Prediction (NCEP) is used as an example to illustrate the impact of model vertical resolution on track forecasts of tropical cyclones. A number of HWRF forecasting experiments were carried out at different vertical resolutions for Hurricane Joaquin, which occurred from September 27 to October 8, 2015, in the Atlantic Basin. The results show that the track prediction for Hurricane Joaquin is much more accurate with higher vertical resolution. The positive impacts of higher vertical resolution on hurricane track forecasts suggest that National Oceanic and Atmospheric Administration/NCEP should upgrade both HWRF and the Global Forecast System to have more vertical levels. PMID- 27698118 TI - Activation of SAT1 engages polyamine metabolism with p53-mediated ferroptotic responses. AB - Although p53-mediated cell-cycle arrest, senescence, and apoptosis remain critical barriers to cancer development, the emerging role of p53 in cell metabolism, oxidative responses, and ferroptotic cell death has been a topic of great interest. Nevertheless, it is unclear how p53 orchestrates its activities in multiple metabolic pathways into tumor suppressive effects. Here, we identified the SAT1 (spermidine/spermine N1-acetyltransferase 1) gene as a transcription target of p53. SAT1 is a rate-limiting enzyme in polyamine catabolism critically involved in the conversion of spermidine and spermine back to putrescine. Surprisingly, we found that activation of SAT1 expression induces lipid peroxidation and sensitizes cells to undergo ferroptosis upon reactive oxygen species (ROS)-induced stress, which also leads to suppression of tumor growth in xenograft tumor models. Notably, SAT1 expression is down-regulated in human tumors, and CRISPR-cas9-mediated knockout of SAT1 expression partially abrogates p53-mediated ferroptosis. Moreover, SAT1 induction is correlated with the expression levels of arachidonate 15-lipoxygenase (ALOX15), and SAT1-induced ferroptosis is significantly abrogated in the presence of PD146176, a specific inhibitor of ALOX15. Thus, our findings uncover a metabolic target of p53 involved in ferroptotic cell death and provide insight into the regulation of polyamine metabolism and ferroptosis-mediated tumor suppression. PMID- 27698120 TI - Stimulating S-adenosyl-l-methionine synthesis extends lifespan via activation of AMPK. AB - Dietary restriction (DR), such as calorie restriction (CR) or methionine (Met) restriction, extends the lifespan of diverse model organisms. Although studies have identified several metabolites that contribute to the beneficial effects of DR, the molecular mechanism underlying the key metabolites responsible for DR regimens is not fully understood. Here we show that stimulating S-adenosyl-l methionine (AdoMet) synthesis extended the lifespan of the budding yeast Saccharomyces cerevisiae The AdoMet synthesis-mediated beneficial metabolic effects, which resulted from consuming both Met and ATP, mimicked CR. Indeed, stimulating AdoMet synthesis activated the universal energy-sensing regulator Snf1, which is the S. cerevisiae ortholog of AMP-activated protein kinase (AMPK), resulting in lifespan extension. Furthermore, our findings revealed that S adenosyl-l-homocysteine contributed to longevity with a higher accumulation of AdoMet only under the severe CR (0.05% glucose) conditions. Thus, our data uncovered molecular links between Met metabolites and lifespan, suggesting a unique function of AdoMet as a reservoir of Met and ATP for cell survival. PMID- 27698122 TI - Simple dynamical models capturing the key features of the Central Pacific El Nino. AB - The Central Pacific El Nino (CP El Nino) has been frequently observed in recent decades. The phenomenon is characterized by an anomalous warm sea surface temperature (SST) confined to the central Pacific and has different teleconnections from the traditional El Nino. Here, simple models are developed and shown to capture the key mechanisms of the CP El Nino. The starting model involves coupled atmosphere-ocean processes that are deterministic, linear, and stable. Then, systematic strategies are developed for incorporating several major mechanisms of the CP El Nino into the coupled system. First, simple nonlinear zonal advection with no ad hoc parameterization of the background SST gradient is introduced that creates coupled nonlinear advective modes of the SST. Secondly, due to the recent multidecadal strengthening of the easterly trade wind, a stochastic parameterization of the wind bursts including a mean easterly trade wind anomaly is coupled to the simple atmosphere-ocean processes. Effective stochastic noise in the wind burst model facilitates the intermittent occurrence of the CP El Nino with realistic amplitude and duration. In addition to the anomalous warm SST in the central Pacific, other major features of the CP El Nino such as the rising branch of the anomalous Walker circulation being shifted to the central Pacific and the eastern Pacific cooling with a shallow thermocline are all captured by this simple coupled model. Importantly, the coupled model succeeds in simulating a series of CP El Nino that lasts for 5 y, which resembles the two CP El Nino episodes during 1990-1995 and 2002-2006. PMID- 27698123 TI - Gate fidelity and coherence of an electron spin in an Si/SiGe quantum dot with micromagnet. AB - The gate fidelity and the coherence time of a quantum bit (qubit) are important benchmarks for quantum computation. We construct a qubit using a single electron spin in an Si/SiGe quantum dot and control it electrically via an artificial spin orbit field from a micromagnet. We measure an average single-qubit gate fidelity of ~99% using randomized benchmarking, which is consistent with dephasing from the slowly evolving nuclear spins in the substrate. The coherence time measured using dynamical decoupling extends up to ~400 MUs for 128 decoupling pulses, with no sign of saturation. We find evidence that the coherence time is limited by noise in the 10-kHz to 1-MHz range, possibly because charge noise affects the spin via the micromagnet gradient. This work shows that an electron spin in an Si/SiGe quantum dot is a good candidate for quantum information processing as well as for a quantum memory, even without isotopic purification. PMID- 27698124 TI - Regulated large-scale nucleosome density patterns and precise nucleosome positioning correlate with V(D)J recombination. AB - We show that the physical distribution of nucleosomes at antigen receptor loci is subject to regulated cell type-specific and lineage-specific positioning and correlates with the accessibility of these gene segments to recombination. At the Ig heavy chain locus (IgH), a nucleosome in pro-B cells is generally positioned over each IgH variable (VH) coding segment, directly adjacent to the recombination signal sequence (RSS), placing the RSS in a position accessible to the recombination activating gene (RAG) recombinase. These changes result in establishment of a specific chromatin organization at the RSS that facilitates accessibility of the genomic DNA for the RAG recombinase. In contrast, in mouse embryonic fibroblasts the coding segment is depleted of nucleosomes, which instead cover the RSS, thereby rendering it inaccessible. Pro-T cells exhibit a pattern intermediate between pro-B cells and mouse embryonic fibroblasts. We also find large-scale variations of nucleosome density over hundreds of kilobases, delineating chromosomal domains within IgH, in a cell type-dependent manner. These findings suggest that developmentally regulated changes in nucleosome location and occupancy, in addition to the known chromatin modifications, play a fundamental role in regulating V(D)J recombination. Nucleosome positioning-which has previously been observed to vary locally at individual enhancers and promoters-may be a more general mechanism by which cells can regulate the accessibility of the genome during development, at scales ranging from several hundred base pairs to many kilobases. PMID- 27698126 TI - Democratic and Republican physicians provide different care on politicized health issues. AB - Physicians frequently interact with patients about politically salient health issues, such as drug use, firearm safety, and sexual behavior. We investigate whether physicians' own political views affect their treatment decisions on these issues. We linked the records of over 20,000 primary care physicians in 29 US states to a voter registration database, obtaining the physicians' political party affiliations. We then surveyed a sample of Democratic and Republican primary care physicians. Respondents evaluated nine patient vignettes, three of which addressed especially politicized health issues (marijuana, abortion, and firearm storage). Physicians rated the seriousness of the issue presented in each vignette and their likelihood of engaging in specific management options. On the politicized health issues-and only on such issues-Democratic and Republican physicians differed substantially in their expressed concern and their recommended treatment plan. We control for physician demographics (like age, gender, and religiosity), patient population, and geography. Physician partisan bias can lead to unwarranted variation in patient care. Awareness of how a physician's political attitudes might affect patient care is important to physicians and patients alike. PMID- 27698125 TI - Mint3 potentiates TLR3/4- and RIG-I-induced IFN-beta expression and antiviral immune responses. AB - Type I IFNs (IFN-alpha/beta) play crucial roles in the elimination of invading viruses. Multiple immune cells including macrophages recognize viral infection through a variety of pattern recognition receptors, such as Toll-like receptors (TLRs) and retinoic acid-inducible gene-I (RIG-I)-like receptors, and initiate type I IFN secretion and subsequent antiviral immune responses. However, the mechanisms by which host immune cells can produce adequate amounts of type I IFNs and then eliminate viruses effectively remain to be further elucidated. In the present study, we show that munc18-1-interacting protein 3 (Mint3) expression can be markedly induced during viral infection in macrophages. Mint3 enhances TLR3/4- and RIG-I-induced IRF3 activation and IFN-beta production by promoting K63-linked polyubiquitination of TNF receptor-associated factor 3 (TRAF3). Consistently, Mint3 deficiency greatly attenuated antiviral immune responses and increased viral replication. Therefore, we have identified Mint3 as a physiological positive regulator of TLR3/4 and RIG-I-induced IFN-beta production and have outlined a feedback mechanism for the control of antiviral immune responses. PMID- 27698127 TI - Environmental change explains cichlid adaptive radiation at Lake Malawi over the past 1.2 million years. AB - Long paleoecological records are critical for understanding evolutionary responses to environmental forcing and unparalleled tools for elucidating the mechanisms that lead to the development of regions of high biodiversity. We use a 1.2-My record from Lake Malawi, a textbook example of biological diversification, to document how climate and tectonics have driven ecosystem and evolutionary dynamics. Before ~800 ka, Lake Malawi was much shallower than today, with higher frequency but much lower amplitude water-level and oxygenation changes. Since ~800 ka, the lake has experienced much larger environmental fluctuations, best explained by a punctuated, tectonically driven rise in its outlet location and level. Following the reorganization of the basin, a change in the pacing of hydroclimate variability associated with the Mid-Pleistocene Transition resulted in hydrologic change dominated by precession rather than the high-latitude teleconnections recorded elsewhere. During this time, extended, deep lake phases have abruptly alternated with times of extreme aridity and ecosystem variability. Repeated crossings of hydroclimatic thresholds within the lake system were critical for establishing the rhythm of diversification, hybridization, and extinction that dominate the modern system. The chronology of these changes closely matches both the timing and pattern of phylogenetic history inferred independently for the lake's extraordinary array of cichlid fish species, suggesting a direct link between environmental and evolutionary dynamics. PMID- 27698128 TI - Large-scale recovery of an endangered amphibian despite ongoing exposure to multiple stressors. AB - Amphibians are one of the most threatened animal groups, with 32% of species at risk for extinction. Given this imperiled status, is the disappearance of a large fraction of the Earth's amphibians inevitable, or are some declining species more resilient than is generally assumed? We address this question in a species that is emblematic of many declining amphibians, the endangered Sierra Nevada yellow legged frog (Rana sierrae). Based on >7,000 frog surveys conducted across Yosemite National Park over a 20-y period, we show that, after decades of decline and despite ongoing exposure to multiple stressors, including introduced fish, the recently emerged disease chytridiomycosis, and pesticides, R. sierrae abundance increased sevenfold during the study and at a rate of 11% per year. These increases occurred in hundreds of populations throughout Yosemite, providing a rare example of amphibian recovery at an ecologically relevant spatial scale. Results from a laboratory experiment indicate that these increases may be in part because of reduced frog susceptibility to chytridiomycosis. The disappearance of nonnative fish from numerous water bodies after cessation of stocking also contributed to the recovery. The large-scale increases in R. sierrae abundance that we document suggest that, when habitats are relatively intact and stressors are reduced in their importance by active management or species' adaptive responses, declines of some amphibians may be partially reversible, at least at a regional scale. Other studies conducted over similarly large temporal and spatial scales are critically needed to provide insight and generality about the reversibility of amphibian declines at a global scale. PMID- 27698129 TI - Negative cooperativity in the nitrogenase Fe protein electron delivery cycle. AB - Nitrogenase catalyzes the ATP-dependent reduction of dinitrogen (N2) to two ammonia (NH3) molecules through the participation of its two protein components, the MoFe and Fe proteins. Electron transfer (ET) from the Fe protein to the catalytic MoFe protein involves a series of synchronized events requiring the transient association of one Fe protein with each alphabeta half of the alpha2beta2 MoFe protein. This process is referred to as the Fe protein cycle and includes binding of two ATP to an Fe protein, association of an Fe protein with the MoFe protein, ET from the Fe protein to the MoFe protein, hydrolysis of the two ATP to two ADP and two Pi for each ET, Pi release, and dissociation of oxidized Fe protein-(ADP)2 from the MoFe protein. Because the MoFe protein tetramer has two separate alphabeta active units, it participates in two distinct Fe protein cycles. Quantitative kinetic measurements of ET, ATP hydrolysis, and Pi release during the presteady-state phase of electron delivery demonstrate that the two halves of the ternary complex between the MoFe protein and two reduced Fe protein-(ATP)2 do not undergo the Fe protein cycle independently. Instead, the data are globally fit with a two-branch negative-cooperativity kinetic model in which ET in one-half of the complex partially suppresses this process in the other. A possible mechanism for communication between the two halves of the nitrogenase complex is suggested by normal-mode calculations showing correlated and anticorrelated motions between the two halves. PMID- 27698130 TI - Exploring the aggregation free energy landscape of the amyloid-beta protein (1 40). AB - A predictive coarse-grained protein force field [associative memory, water mediated, structure, and energy model for molecular dynamics (AWSEM)-MD] is used to study the energy landscapes and relative stabilities of amyloid-beta protein (1-40) in the monomer and all of its oligomeric forms up to an octamer. We find that an isolated monomer is mainly disordered with a short alpha-helix formed at the central hydrophobic core region (L17-D23). A less stable hairpin structure, however, becomes increasingly more stable in oligomers, where hydrogen bonds can form between neighboring monomers. We explore the structure and stability of both prefibrillar oligomers that consist of mainly antiparallel beta-sheets and fibrillar oligomers with only parallel beta-sheets. Prefibrillar oligomers are polymorphic but typically take on a cylindrin-like shape composed of mostly antiparallel beta-strands. At the concentration of the simulation, the aggregation free energy landscape is nearly downhill. We use umbrella sampling along a structural progress coordinate for interconversion between prefibrillar and fibrillar forms to identify a conversion pathway between these forms. The fibrillar oligomer only becomes favored over its prefibrillar counterpart in the pentamer where an interconversion bottleneck appears. The structural characterization of the pathway along with statistical mechanical perturbation theory allow us to evaluate the effects of concentration on the free energy landscape of aggregation as well as the effects of the Dutch and Arctic mutations associated with early onset of Alzheimer's disease. PMID- 27698131 TI - Lifespan adversity and later adulthood telomere length in the nationally representative US Health and Retirement Study. AB - Stress over the lifespan is thought to promote accelerated aging and early disease. Telomere length is a marker of cell aging that appears to be one mediator of this relationship. Telomere length is associated with early adversity and with chronic stressors in adulthood in many studies. Although cumulative lifespan adversity should have bigger impacts than single events, it is also possible that adversity in childhood has larger effects on later life health than adult stressors, as suggested by models of biological embedding in early life. No studies have examined the individual vs. cumulative effects of childhood and adulthood adversities on adult telomere length. Here, we examined the relationship between cumulative childhood and adulthood adversity, adding up a range of severe financial, traumatic, and social exposures, as well as comparing them to each other, in relation to salivary telomere length. We examined 4,598 men and women from the US Health and Retirement Study. Single adversities tended to have nonsignificant relations with telomere length. In adjusted models, lifetime cumulative adversity predicted 6% greater odds of shorter telomere length. This result was mainly due to childhood adversity. In adjusted models for cumulative childhood adversity, the occurrence of each additional childhood event predicted 11% increased odds of having short telomeres. This result appeared mainly because of social/traumatic exposures rather than financial exposures. This study suggests that the shadow of childhood adversity may reach far into later adulthood in part through cellular aging. PMID- 27698132 TI - Epitope specificity plays a critical role in regulating antibody-dependent cell mediated cytotoxicity against influenza A virus. AB - The generation of strain-specific neutralizing antibodies against influenza A virus is known to confer potent protection against homologous infections. The majority of these antibodies bind to the hemagglutinin (HA) head domain and function by blocking the receptor binding site, preventing infection of host cells. Recently, elicitation of broadly neutralizing antibodies which target the conserved HA stalk domain has become a promising "universal" influenza virus vaccine strategy. The ability of these antibodies to elicit Fc-dependent effector functions has emerged as an important mechanism through which protection is achieved in vivo. However, the way in which Fc-dependent effector functions are regulated by polyclonal influenza virus-binding antibody mixtures in vivo has never been defined. Here, we demonstrate that interactions among viral glycoprotein-binding antibodies of varying specificities regulate the magnitude of antibody-dependent cell-mediated cytotoxicity induction. We show that the mechanism responsible for this phenotype relies upon competition for binding to HA on the surface of infected cells and virus particles. Nonneutralizing antibodies were poor inducers and did not inhibit antibody-dependent cell mediated cytotoxicity. Interestingly, anti-neuraminidase antibodies weakly induced antibody-dependent cell-mediated cytotoxicity and enhanced induction in the presence of HA stalk-binding antibodies in an additive manner. Our data demonstrate that antibody specificity plays an important role in the regulation of ADCC, and that cross-talk among antibodies of varying specificities determines the magnitude of Fc receptor-mediated effector functions. PMID- 27698135 TI - Genomic charting of ribosomally synthesized natural product chemical space facilitates targeted mining. AB - Microbial natural products are an evolved resource of bioactive small molecules, which form the foundation of many modern therapeutic regimes. Ribosomally synthesized and posttranslationally modified peptides (RiPPs) represent a class of natural products which have attracted extensive interest for their diverse chemical structures and potent biological activities. Genome sequencing has revealed that the vast majority of genetically encoded natural products remain unknown. Many bioinformatic resources have therefore been developed to predict the chemical structures of natural products, particularly nonribosomal peptides and polyketides, from sequence data. However, the diversity and complexity of RiPPs have challenged systematic investigation of RiPP diversity, and consequently the vast majority of genetically encoded RiPPs remain chemical "dark matter." Here, we introduce an algorithm to catalog RiPP biosynthetic gene clusters and chart genetically encoded RiPP chemical space. A global analysis of 65,421 prokaryotic genomes revealed 30,261 RiPP clusters, encoding 2,231 unique products. We further leverage the structure predictions generated by our algorithm to facilitate the genome-guided discovery of a molecule from a rare family of RiPPs. Our results provide the systematic investigation of RiPP genetic and chemical space, revealing the widespread distribution of RiPP biosynthesis throughout the prokaryotic tree of life, and provide a platform for the targeted discovery of RiPPs based on genome sequencing. PMID- 27698136 TI - Breaking the symmetry of a viral capsid. PMID- 27698133 TI - Epstein-Barr virus microRNAs reduce immune surveillance by virus-specific CD8+ T cells. AB - Infection with Epstein-Barr virus (EBV) affects most humans worldwide and persists life-long in the presence of robust virus-specific T-cell responses. In both immunocompromised and some immunocompetent people, EBV causes several cancers and lymphoproliferative diseases. EBV transforms B cells in vitro and encodes at least 44 microRNAs (miRNAs), most of which are expressed in EBV transformed B cells, but their functions are largely unknown. Recently, we showed that EBV miRNAs inhibit CD4+ T-cell responses to infected B cells by targeting IL 12, MHC class II, and lysosomal proteases. Here we investigated whether EBV miRNAs also counteract surveillance by CD8+ T cells. We have found that EBV miRNAs strongly inhibit recognition and killing of infected B cells by EBV specific CD8+ T cells through multiple mechanisms. EBV miRNAs directly target the peptide transporter subunit TAP2 and reduce levels of the TAP1 subunit, MHC class I molecules, and EBNA1, a protein expressed in most forms of EBV latency and a target of EBV-specific CD8+ T cells. Moreover, miRNA-mediated down-regulation of the cytokine IL-12 decreases the recognition of infected cells by EBV-specific CD8+ T cells. Thus, EBV miRNAs use multiple, distinct pathways, allowing the virus to evade surveillance not only by CD4+ but also by antiviral CD8+ T cells. PMID- 27698137 TI - System crash as dynamics of complex networks. AB - Complex systems, from animal herds to human nations, sometimes crash drastically. Although the growth and evolution of systems have been extensively studied, our understanding of how systems crash is still limited. It remains rather puzzling why some systems, appearing to be doomed to fail, manage to survive for a long time whereas some other systems, which seem to be too big or too strong to fail, crash rapidly. In this contribution, we propose a network-based system dynamics model, where individual actions based on the local information accessible in their respective system structures may lead to the "peculiar" dynamics of system crash mentioned above. Extensive simulations are carried out on synthetic and real-life networks, which further reveal the interesting system evolution leading to the final crash. Applications and possible extensions of the proposed model are discussed. PMID- 27698134 TI - Cancer cells enter dormancy after cannibalizing mesenchymal stem/stromal cells (MSCs). AB - Patients with breast cancer often develop malignant regrowth of residual drug resistant dormant tumor cells years after primary treatment, a process defined as cancer relapse. Deciphering the causal basis of tumor dormancy therefore has obvious therapeutic significance. Because cancer cell behavior is strongly influenced by stromal cells, particularly the mesenchymal stem/stromal cells (MSCs) that are actively recruited into tumor-associated stroma, we assessed the impact of MSCs on breast cancer cell (BCC) dormancy. Using 3D cocultures to mimic the cellular interactions of an emerging tumor niche, we observed that MSCs sequentially surrounded the BCCs, promoted formation of cancer spheroids, and then were internalized/degraded through a process resembling the well-documented yet ill-defined clinical phenomenon of cancer cell cannibalism. This suspected feeding behavior was less appreciable in the presence of a rho kinase inhibitor and in 2D monolayer cocultures. Notably, cannibalism of MSCs enhanced survival of BCCs deprived of nutrients but suppressed their tumorigenicity, together suggesting the cancer cells entered dormancy. Transcriptome profiles revealed that the resulting BCCs acquired a unique molecular signature enriched in prosurvival factors and tumor suppressors, as well as inflammatory mediators that demarcate the secretome of senescent cells, also referred to as the senescence associated secretory phenotype. Overall, our results provide intriguing evidence that cancer cells under duress enter dormancy after cannibalizing MSCs. Importantly, our practical 3D coculture model could provide a valuable tool to understand the antitumor activity of MSCs and cell cannibalism further, and therefore open new therapeutic avenues for the prevention of cancer recurrence. PMID- 27698139 TI - QnAs with Alan G. Hinnebusch. PMID- 27698138 TI - Mushroom spine dynamics in medium spiny neurons of dorsal striatum associated with memory of moderate and intense training. AB - A growing body of evidence indicates that treatments that typically impair memory consolidation become ineffective when animals are given intense training. This effect has been obtained by treatments interfering with the neural activity of several brain structures, including the dorsal striatum. The mechanisms that mediate this phenomenon are unknown. One possibility is that intense training promotes the transfer of information derived from the enhanced training to a wider neuronal network. We now report that inhibitory avoidance (IA) induces mushroom spinogenesis in the medium spiny neurons (MSNs) of the dorsal striatum in rats, which is dependent upon the intensity of the foot-shock used for training; that is, the effect is seen only when high-intensity foot-shock is used in training. We also found that the relative density of thin spines was reduced. These changes were evident at 6 h after training and persisted for at least 24 h afterward. Importantly, foot-shock alone did not increase spinogenesis. Spine density in MSNs in the accumbens was also increased, but the increase did not correlate with the associative process involved in IA; rather, it resulted from the administration of the aversive stimulation alone. These findings suggest that mushroom spines of MSNs of the dorsal striatum receive afferent information that is involved in the integrative activity necessary for memory consolidation, and that intense training facilitates transfer of information from the dorsal striatum to other brain regions through augmented spinogenesis. PMID- 27698140 TI - Spectroscopic elucidation of energy transfer in hybrid inorganic-biological organisms for solar-to-chemical production. AB - The rise of inorganic-biological hybrid organisms for solar-to-chemical production has spurred mechanistic investigations into the dynamics of the biotic abiotic interface to drive the development of next-generation systems. The model system, Moorella thermoacetica-cadmium sulfide (CdS), combines an inorganic semiconductor nanoparticle light harvester with an acetogenic bacterium to drive the photosynthetic reduction of CO2 to acetic acid with high efficiency. In this work, we report insights into this unique electrotrophic behavior and propose a charge-transfer mechanism from CdS to M. thermoacetica Transient absorption (TA) spectroscopy revealed that photoexcited electron transfer rates increase with increasing hydrogenase (H2ase) enzyme activity. On the same time scale as the TA spectroscopy, time-resolved infrared (TRIR) spectroscopy showed spectral changes in the 1,700-1,900-cm-1 spectral region. The quantum efficiency of this system for photosynthetic acetic acid generation also increased with increasing H2ase activity and shorter carrier lifetimes when averaged over the first 24 h of photosynthesis. However, within the initial 3 h of photosynthesis, the rate followed an opposite trend: The bacteria with the lowest H2ase activity photosynthesized acetic acid the fastest. These results suggest a two-pathway mechanism: a high quantum efficiency charge-transfer pathway to H2ase generating H2 as a molecular intermediate that dominates at long time scales (24 h), and a direct energy-transducing enzymatic pathway responsible for acetic acid production at short time scales (3 h). This work represents a promising platform to utilize conventional spectroscopic methodology to extract insights from more complex biotic-abiotic hybrid systems.

AB - The notion of complex energy landscape underpins the intriguing dynamical behaviors in many complex systems ranging from polymers, to brain activity, to social networks and glass transitions. The spin glass state found in dilute magnetic alloys has been an exceptionally convenient laboratory frame for studying complex dynamics resulting from a hierarchical energy landscape with rugged funnels. Here, we show, by a bulk susceptibility and Monte Carlo simulation study, that densely populated frustrated magnets in a spin jam state exhibit much weaker memory effects than spin glasses, and the characteristic properties can be reproduced by a nonhierarchical landscape with a wide and nearly flat but rough bottom. Our results illustrate that the memory effects can be used to probe different slow dynamics of glassy materials, hence opening a window to explore their distinct energy landscapes.

Primed enhancers are marked by histone H3 lysine 4 (H3K4) mono/di-methylation (H3K4me1/2). Active enhancers are further marked by H3K27 acetylation (H3K27ac). Mixed-lineage leukemia 4 (MLL4/KMT2D) is a major enhancer H3K4me1/2 methyltransferase with functional redundancy with MLL3 (KMT2C). However, its role in cell fate maintenance and transition is poorly understood. Here, we show in mouse embryonic stem cells (ESCs) that MLL4 associates with, but is surprisingly dispensable for the maintenance of, active enhancers of cell-identity genes. As a result, MLL4 is dispensable for cell-identity gene expression and self-renewal in ESCs. In contrast, MLL4 is required for enhancer-binding of H3K27 acetyltransferase p300, enhancer activation, and induction of cell-identity genes during ESC differentiation. MLL4 protein, rather than MLL4-mediated H3K4 methylation, controls p300 recruitment to enhancers. We also show that, in somatic cells, MLL4 is dispensable for maintaining cell identity but essential for reprogramming into induced pluripotent stem cells. These results indicate that, although enhancer priming by MLL4 is dispensable for cell-identity maintenance, it controls cell fate transition by orchestrating p300-mediated enhancer activation.

AB - A conserved stress energy tensor for weak field gravitational waves propagating in vacuum is derived directly from the linearized general relativistic wave equation alone, for an arbitrary gauge. In any harmonic gauge, the form of the tensor leads directly to the classical expression for the outgoing wave energy. The method described here, however, is a much simpler, shorter, and more physically motivated approach than is the customary procedure, which involves a lengthy and cumbersome second-order (in wave-amplitude) calculation starting with the Einstein tensor. Our method has the added advantage of exhibiting the direct coupling between the outgoing wave energy flux and the work done by the gravitational field on the sources. For nonharmonic gauges, the directly derived wave stress tensor has an apparent index asymmetry. This coordinate artifact may be straightforwardly removed, and the symmetrized (still gauge-invariant) tensor then takes on its widely used form. Angular momentum conservation follows immediately. For any harmonic gauge, however, the stress tensor found is manifestly symmetric from the start, and its derivation depends, in its entirety, on the structure of the linearized wave equation. PMID- 27698144 TI - Disorder drives cooperative folding in a multidomain protein. AB - Many human proteins contain intrinsically disordered regions, and disorder in these proteins can be fundamental to their function-for example, facilitating transient but specific binding, promoting allostery, or allowing efficient posttranslational modification. SasG, a multidomain protein implicated in host colonization and biofilm formation in Staphylococcus aureus, provides another example of how disorder can play an important role. Approximately one-half of the domains in the extracellular repetitive region of SasG are intrinsically unfolded in isolation, but these E domains fold in the context of their neighboring folded G5 domains. We have previously shown that the intrinsic disorder of the E domains mediates long-range cooperativity between nonneighboring G5 domains, allowing SasG to form a long, rod-like, mechanically strong structure. Here, we show that the disorder of the E domains coupled with the remarkable stability of the interdomain interface result in cooperative folding kinetics across long distances. Formation of a small structural nucleus at one end of the molecule results in rapid structure formation over a distance of 10 nm, which is likely to be important for the maintenance of the structural integrity of SasG. Moreover, if this normal folding nucleus is disrupted by mutation, the interdomain interface is sufficiently stable to drive the folding of adjacent E and G5 domains along a parallel folding pathway, thus maintaining cooperative folding. PMID- 27698145 TI - Genetic mapping of male pheromone response in the European corn borer identifies candidate genes regulating neurogenesis. AB - The sexual pheromone communication system of moths is a model system for studies of the evolution of reproductive isolation. Females emit a blend of volatile components that males detect at a distance. Species differences in female pheromone composition and male response directly reinforce reproductive isolation in nature, because even slight variations in the species-specific pheromone blend are usually rejected by the male. The mechanisms by which a new pheromone signal response system could evolve are enigmatic, because any deviation from the optimally attractive blend should be selected against. Here we investigate the genetic mechanisms enabling a switch in male response. We used a quantitative trait locus-mapping approach to identify the genetic basis of male response in the two pheromone races of the European corn borer, Ostrinia nubilalis Male response to a 99:1 vs. a 3:97 ratio of the E and Z isomers of the female pheromone is governed by a single, sex-linked locus. We found that the chromosomal region most tightly linked to this locus contains genes involved in neurogenesis but, in accordance with an earlier study, does not contain the odorant receptors expressed in the male antenna that detect the pheromone. This finding implies that differences in the development of neuronal pathways conveying information from the antenna, not differences in pheromone detection by the odorant receptors, are primarily responsible for the behavioral response differences among the males in this system. Comparison with other moth species reveals a previously unexplored mechanism by which male pheromone response can change in evolution. PMID- 27698146 TI - A competing hydrophobic tug on L596 to the membrane core unlatches S4-S5 linker elbow from TRP helix and allows TRPV4 channel to open. AB - We have some generalized physical understanding of how ion channels interact with surrounding lipids but few detailed descriptions on how interactions of particular amino acids with contacting lipids may regulate gating. Here we discovered a structure-specific interaction between an amino acid and inner leaflet lipid that governs the gating transformations of TRPV4 (transient receptor potential vanilloid type 4). Many cation channels use a S4-S5 linker to transmit stimuli to the gate. At the start of TRPV4's linker helix is leucine 596. A hydrogen bond between the indole of W733 of the TRP helix and the backbone oxygen of L596 secures the helix/linker contact, which acts as a latch maintaining channel closure. The modeled side chain of L596 interacts with the inner lipid leaflet near the polar-nonpolar interface in our model-an interaction that we explored by mutagenesis. We examined the outward currents of TRPV4 expressing Xenopus oocyte upon depolarizations as well as phenotypes of expressing yeast cells. Making this residue less hydrophobic (L596A/G/W/Q/K) reduces open probability [Po; loss-of-function (LOF)], likely due to altered interactions at the polar-nonpolar interface. L596I raises Po [gain-of-function (GOF)], apparently by placing its methyl group further inward and receiving stronger water repulsion. Molecular dynamics simulations showed that the distance between the levels of alpha-carbons of H-bonded residues L596 and W733 is shortened in the LOFs and lengthened in the GOFs, strengthening or weakening the linker/TRP helix latch, respectively. These results highlight that L596 lipid attraction counteracts the latch bond in a tug-of-war to tune the Po of TRPV4. PMID- 27698147 TI - Designing steep, sharp patterns on uniformly ion-bombarded surfaces. AB - We propose and experimentally test a method to fabricate patterns of steep, sharp features on surfaces, by exploiting the nonlinear dynamics of uniformly ion bombarded surfaces. We show via theory, simulation, and experiment that the steepest parts of the surface evolve as one-dimensional curves that move in the normal direction at constant velocity. The curves are a special solution to the nonlinear equations that arises spontaneously whenever the initial patterning on the surface contains slopes larger than a critical value; mathematically they are traveling waves (shocks) that have the special property of being undercompressive. We derive the evolution equation for the curves by considering long-wavelength perturbations to the one-dimensional traveling wave, using the unusual boundary conditions required for an undercompressive shock, and we show this equation accurately describes the evolution of shapes on surfaces, both in simulations and in experiments. Because evolving a collection of one-dimensional curves is fast, this equation gives a computationally efficient and intuitive method for solving the inverse problem of finding the initial surface so the evolution leads to a desired target pattern. We illustrate this method by solving for the initial surface that will produce a lattice of diamonds connected by steep, sharp ridges, and we experimentally demonstrate the evolution of the initial surface into the target pattern. PMID- 27698150 TI - Trend of homicide-suicide in Kanagawa Prefecture (Japan): Comparison with western countries. AB - We examined 169 deceased persons and 76 homicide-suicide cases reported in Japan's Kanagawa Prefecture from 1999 to 2011. The relationships between homicide suicide perpetrators and homicide victims; the numbers of victims; their age, sex, causes and places of death; motivation; and the presence or absence of a suicide note were extracted and examined. The relationship between homicide suicide perpetrators and homicide victims was examined based on findings from the following: 24 married couples (31%), 22 parents and children aged >=18 years (29%), 19 parents and children aged <=17 years (25%), seven families (9%), two couples (3%) and two miscellaneous relationships (3%). The perpetrators comprised 39 men and 40 women, with a mean age of 51.6 years. The victims comprised 39 men and 51 women, with a mean age of 35.4 years. In our study, approximately half of the perpetrators were female, which differed greatly from the reports from Western countries, where most perpetrators were male. Homicide-suicides among married couples accounted for a higher proportion of overall homicide-suicide deaths in Western countries. In Japan, homicide-suicide occurred more frequently with parents and children. Cases in which a mother committed suicide after having killed her young children accounted for a high proportion of these deaths. Because these events occur so frequently in Japan, we recommend making particular efforts to reduce homicide-suicides among mothers and children. PMID- 27698148 TI - Multiscale implementation of infinite-swap replica exchange molecular dynamics. AB - Replica exchange molecular dynamics (REMD) is a popular method to accelerate conformational sampling of complex molecular systems. The idea is to run several replicas of the system in parallel at different temperatures that are swapped periodically. These swaps are typically attempted every few MD steps and accepted or rejected according to a Metropolis-Hastings criterion. This guarantees that the joint distribution of the composite system of replicas is the normalized sum of the symmetrized product of the canonical distributions of these replicas at the different temperatures. Here we propose a different implementation of REMD in which (i) the swaps obey a continuous-time Markov jump process implemented via Gillespie's stochastic simulation algorithm (SSA), which also samples exactly the aforementioned joint distribution and has the advantage of being rejection free, and (ii) this REMD-SSA is combined with the heterogeneous multiscale method to accelerate the rate of the swaps and reach the so-called infinite-swap limit that is known to optimize sampling efficiency. The method is easy to implement and can be trivially parallelized. Here we illustrate its accuracy and efficiency on the examples of alanine dipeptide in vacuum and C-terminal beta-hairpin of protein G in explicit solvent. In this latter example, our results indicate that the landscape of the protein is a triple funnel with two folded structures and one misfolded structure that are stabilized by H-bonds. PMID- 27698149 TI - Respiratory and Enteric Virus Detection in Children. AB - The majority of children with febrile seizures have viral infections and viruses were detected in 22% to 63% of children in published studies. Using molecular methods, viruses were also detected in asymptomatic persons. A prospective study was conducted to detect respiratory and enteric viruses in 192 children with febrile seizures and compare the detection rates to those found in 156 healthy age-matched controls. A respiratory or enteric virus was detected in 72.9% of children with febrile seizures and in 51.4% of healthy controls. The viruses most strongly associated with febrile seizures were influenza, respiratory syncytial virus, parainfluenza, human coronavirus, and rotavirus. Compared to healthy controls, the age-adjusted odds ratios for nasopharynx virus positivity in febrile seizure patients were 79.4, 2.8, 7.2, and 4.9 for influenza virus, parainfluenza virus, respiratory syncytial virus, and human coronavirus, respectively, and 22.0 for rotavirus in stool. The detected virus did not influence clinical features of febrile seizure. PMID- 27698151 TI - Bilateral injury of the superior longitudinal fasciculus in a patient with Balint syndrome.

AB - A diagnosis of neoplasia was noted in 125 of 357 donkeys (35%) in our review of medical records from 5 veterinary schools in the United States and Canada. Equine sarcoid was the most common tumor in our study, accounting for 72% of all tumors and 82% of cutaneous tumors. Soft-tissue sarcomas were the second most common skin tumors. All other types of neoplasia were rare. Important differences in the occurrence of neoplasia in donkeys compared to horses included the rarity or absence of squamous cell carcinoma in any organ system and gray horse melanoma. Lymphosarcoma, the most common malignant tumor in horses, appears to be very rare in donkeys. We report several tumors in donkeys including melanocytoma, peripheral nerve sheath tumor, and gastrointestinal stromal tumor. Our data demonstrate commonalities as well as differences in neoplastic diseases of donkeys and horses. Understanding differences in carcinogenesis among these 2 closely related species can inform researchers pursuing pathogenic mechanisms of equine disease and inform veterinary diagnosticians regarding tumor prevalence. PMID- 27698163 TI - Tissue localization, shedding, virus carriage, antibody response, and aerosol transmission of Porcine epidemic diarrhea virus following inoculation of 4-week old feeder pigs. AB - We determined tissue localization, shedding patterns, virus carriage, antibody response, and aerosol transmission of Porcine epidemic diarrhea virus (PEDV) following inoculation of 4-week-old feeder pigs. Thirty-three pigs were randomly assigned to 1 of 3 groups for the 42-day study: inoculated (group A; n = 23), contact transmission (group B; n = 5), and aerosol transmission (group C; n = 5). Contact transmission occurred rapidly to group B pigs whereas productive aerosol transmission failed to occur to group C pigs. Emesis was the first clinical sign noted at 3 days postinoculation (dpi) followed by mild to moderate diarrhea lasting 5 more days. Real-time PCR detected PEDV in fecal and nasal swabs, oral fluids, serum, and gastrointestinal and lymphoid tissues. Shedding occurred primarily during the first 2 weeks postinoculation, peaking at 5-6 dpi; however, some pigs had PEDV nucleic acid detected in swabs collected at 21 and 28 dpi. Antibody titers were measurable between 14 and 42 dpi. Although feces and intestines collected at 42 dpi were PEDV negative by PCR and immunohistochemistry, respectively, small intestines from 70% of group A pigs were PCR positive. Although disease was relatively mild and transient in this age group, the results demonstrate that 4-week-old pigs are productively infected and can sustain virus replication for several weeks. Long-term shedding of PEDV in subclinically affected pigs should be considered an important source for PEDV transmission. PMID- 27698165 TI - Concurrent spindle-cell thymoma and thymic cysts in a Barbary sheep (Ammotragus lervia): case report and review of the literature. AB - An ~21-year-old female Barbary sheep (Ammotragus lervia) died spontaneously following a lengthy episode of difficulty in walking. An ~6 * 3 * 3 cm, unilocular cystic growth was found in the cranioventral thorax. The fibrotic cystic wall, lined by a single layer of flattened to cuboidal epithelial cells, was invaginated and partially encircled solid masses of fusiform neoplastic cells with multiple intratumoral cystic structures. The fusiform neoplastic cells were intensely positive for cytokeratin (CK) and partially positive for alpha-smooth muscle actin and vimentin, but negative for thyroid transcription factor-1 (TTF 1) and neuron-specific enolase (NSE). The intratumoral cysts were lined by CK positive but TTF-1- negative, NSE-negative, flattened, cuboidal to columnar epithelial cells, suggestive of cystically dilated medullary duct epithelium derived structures. Based on the location and histopathologic findings of the growth, concurrent spindle-cell thymoma and thymic cysts was diagnosed. We also discuss the correlation between thymic cysts and thymoma and review the literature of thymomas in ovine and wildlife species. PMID- 27698164 TI - Isolation and identification of Caviibacter abscessus from cervical abscesses in a series of pet guinea pigs (Cavia porcellus). AB - An organism reported in the early literature to be a rare cause of cervical lymphadenitis in guinea pigs, Streptobacillus moniliformis, has been reclassified as Caviibacter abscessus We describe a series of sequential cases of abscesses in guinea pigs that were presented to our clinic from which the only agent isolated was a unique, serum-requiring bacterium. Discrete colonies were not detected in 6.5% CO2 or anaerobically on routine primary isolation media containing up to 5% whole sheep blood, with and without cysteine, vitamin K, and hemin supplementation after 7 days of incubation at 37 degrees C. Based on subsequently determined growth requirements, the organisms were best described as serum requiring, aerotolerant anaerobes. Colonies were detectable within 24 h at 37 degrees C in an anaerobic atmosphere on a mycoplasma agar-based medium containing 10% pig serum and reached 3 mm in diameter within 3-5 days. Microscopic appearance consisted of small gram-negative rods and coccobacilli with occasional filaments. However, in direct smears from clinical specimens and from weak or dysgonic growth on plates incubated under suboptimal growth conditions (e.g., in 6.5% CO2), irregular rods with occasional small bulbous forms or numerous long wavy filaments were observed. All of the isolates generated unique spectral profiles similar to that of C. abscessus when examined by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Phylogenetic analysis of partial 16S rRNA gene sequences showed that the isolates were identical to each other and shared 99.9% sequence identity with C. abscessus. PMID- 27698166 TI - Validation of three automated assays for total antioxidant capacity determination in canine serum samples. AB - We performed analytical validation of 3 automated assays of the total antioxidant capacity (TAC) in canine serum and evaluated their use in dogs with inflammatory bowel disease. The assays were based on the generation of a 2,2'-azino-bis(3 ethylbenzthiazoline-6-sulfonic acid) radical cation (ABTS*+) in aqueous media, which produces a blue-green color. The antioxidants present in the sample remove the chromogen in proportion to their concentrations. The assays differed mainly in the way in which this radical was produced. All 3 assays produced acceptable results in the analytical validation. However, only 2 of the assays were capable of detecting significantly different TAC values in healthy and diseased animals. PMID- 27698167 TI - Hernia of the swim bladder (aerocystocele) with concurrent mycotic granulomatous inflammation and swim bladder carcinoma in a wild mullet (Mugil cephalus). AB - We describe a hernia of the swim bladder, with a concurrent mycotic granulomatous inflammation, and carcinoma of the swim bladder in a wild mullet (Mugil cephalus) referred for an exophytic dorsal mass. Grossly, the mass was white, soft, and composed of multiple cystic gas-containing chambers connected by a funnel-shaped tissue segment to the coelomic swim bladder. Histologically, the mass was characterized by cysts of variable size, multifocally contiguous with the subepithelial rete mirabile, supported by abundant fibrous tissue. The skin covering the herniated swim bladder was focally ulcerated and replaced by abundant granulation tissue in which multiple scattered granulomas centered on pigmented fungal hyphae were observed. These granulomas were also seen in the remaining coelomic portion of the swim bladder as well as in the spleen, perivisceral pancreas, and peritoneal adipose tissue; the fungus was molecularly identified as Cladosporium spp. Focally, arising from the herniated swim bladder epithelium, an unencapsulated poorly demarcated, moderately cellular neoplasm, composed of islands, lobules, and acini of neoplastic epithelium, was found. PMID- 27698168 TI - Evaluation of supervised machine-learning algorithms to distinguish between inflammatory bowel disease and alimentary lymphoma in cats. AB - Inflammatory bowel disease (IBD) and alimentary lymphoma (ALA) are common gastrointestinal diseases in cats. The very similar clinical signs and histopathologic features of these diseases make the distinction between them diagnostically challenging. We tested the use of supervised machine-learning algorithms to differentiate between the 2 diseases using data generated from noninvasive diagnostic tests. Three prediction models were developed using 3 machine-learning algorithms: naive Bayes, decision trees, and artificial neural networks. The models were trained and tested on data from complete blood count (CBC) and serum chemistry (SC) results for the following 3 groups of client-owned cats: normal, inflammatory bowel disease (IBD), or alimentary lymphoma (ALA). Naive Bayes and artificial neural networks achieved higher classification accuracy (sensitivities of 70.8% and 69.2%, respectively) than the decision tree algorithm (63%, p < 0.0001). The areas under the receiver-operating characteristic curve for classifying cases into the 3 categories was 83% by naive Bayes, 79% by decision tree, and 82% by artificial neural networks. Prediction models using machine learning provided a method for distinguishing between ALA IBD, ALA-normal, and IBD-normal. The naive Bayes and artificial neural networks classifiers used 10 and 4 of the CBC and SC variables, respectively, to outperform the C4.5 decision tree, which used 5 CBC and SC variables in classifying cats into the 3 classes. These models can provide another noninvasive diagnostic tool to assist clinicians with differentiating between IBD and ALA, and between diseased and nondiseased cats. PMID- 27698169 TI - Evaluation of a PCR assay on overgrown environmental samples cultured for Mycobacterium avium subsp. paratuberculosis. AB - Culture of Mycobacterium avium subsp. paratuberculosis (MAP) is the definitive antemortem test method for paratuberculosis. Microbial overgrowth is a challenge for MAP culture, as it complicates, delays, and increases the cost of the process. Additionally, herd status determination is impeded when noninterpretable (NI) results are obtained. The performance of PCR is comparable to fecal culture, thus it may be a complementary detection tool to classify NI samples. Our study aimed to determine if MAP DNA can be identified by PCR performed on NI environmental samples and to evaluate the performance of PCR before and after the culture of these samples in liquid media. A total of 154 environmental samples (62 NI, 62 negative, and 30 positive) were analyzed by PCR before being incubated in an automated system. Growth was confirmed by acid-fast bacilli stain and then the same PCR method was again applied on incubated samples, regardless of culture and stain results. Change in MAP DNA after incubation was assessed by converting the PCR quantification cycle (Cq) values into fold change using the 2-DeltaCq method (DeltaCq = Cq after culture - Cq before culture). A total of 1.6% (standard error [SE] = 1.6) of the NI environmental samples had detectable MAP DNA. The PCR had a significantly better performance when applied after culture than before culture (p = 0.004). After culture, a 66-fold change (SE = 17.1) in MAP DNA was observed on average. Performing a PCR on NI samples improves MAP culturing. The PCR method used in our study is a reliable and consistent method to classify NI environmental samples. PMID- 27698170 TI - Snake fungal disease caused by Ophidiomyces ophiodiicola in a free-ranging mud snake (Farancia abacura). AB - Snake fungal disease is an emerging infectious disease caused by the fungus Ophidiomyces ophiodiicola leading to severe dermatitis and facial disfiguration in numerous free-ranging and captive snakes. A free-ranging mud snake (Farancia abacura) from Bulloch County, Georgia, was presented for autopsy because of facial swelling and emaciation. Extensive ulceration of the skin, which was especially severe on the head, and retained shed were noted on external examination. Microscopic examination revealed severe heterophilic dermatitis with intralesional fungal hyphae and arthroconidia consistent with O. ophiodiicola A skin sample incubated on Sabouraud dextrose agar yielded a white-to-tan powdery fungal culture that was confirmed to be O. ophiodiicola by polymerase chain reaction and sequence analysis. Heavy infestation with adult tapeworms (Ophiotaenia faranciae) was present within the intestine. Various bacterial and fungal species, interpreted to either be secondary invaders or postmortem contaminants, were associated with oral lesions. Although the role of these other organisms in the overall health of this individual is not known, factors such as concurrent infections or immunosuppression should be considered in order to better understand the overall manifestation of snake fungal disease, which remains poorly characterized in its host range and geographic distribution. PMID- 27698171 TI - Mycobacterium haemophilum infection in a juvenile leatherback sea turtle (Dermochelys coriacea). AB - Mycobacteriosis is infrequently reported in free-ranging sea turtles. Nontuberculous Mycobacterium haemophilum was identified as the causative agent of disseminated mycobacteriosis in a juvenile leatherback turtle (Dermochelys coriacea) that was found stranded on the Atlantic coast of Florida. Disseminated granulomatous inflammation was identified histologically, most notably affecting the nervous system. Identification of mycobacterial infection was based on cytologic, molecular, histologic, and microbiologic methods. Among stranded sea turtles received for diagnostic evaluation from the Atlantic and Gulf of Mexico coasts of the United States between 2004 and 2015, the diagnosis of mycobacteriosis was overrepresented in stranded oceanic-phase juveniles compared with larger size classes, which suggests potential differences in susceptibility or exposure among different life phases in this region. We describe M. haemophilum in a sea turtle, which contributes to the knowledge of diseases of small juvenile sea turtles, an especially cryptic life phase of the leatherback turtle. PMID- 27698172 TI - Unclassified sarcomas: a study to improve classification in a cohort of Golden Retriever dogs. AB - Morphologically, canine soft-tissue sarcomas (STSs) resemble human STSs. In humans, proper classification of STSs is considered essential to improve insight in the biology of these tumors, and to optimize diagnosis and therapy. To date, there is a paucity of data published on the significance of detailed classification of STSs in the dog. We revised a cohort (n = 110) of proliferative lesions obtained from a study in Golden Retrievers that were considered "soft tissue sarcoma, not otherwise specified or of uncertain subtype" in order to optimize the diagnoses of these lesions. The criteria according to the veterinary WHO classification, recent veterinary literature, and the WHO classification for humans were applied. Revision was initially based on morphologic characteristics of hematoxylin and eosin-stained histologic sections of the neoplasms. If considered necessary (n = 76), additional immunohistochemistry was applied to aid characterization. The diagnosis of STS was confirmed in 75 neoplasms (68%). Of this group, diagnosis of a specific subtype of the STSs was possible in 58 neoplasms. Seven neoplasms had morphologic characteristics that were suggestive for sarcoma subtypes only described in the WHO classification for humans. Seventeen neoplasms remained "unclassified STSs." Thirty-one lesions (28%) were diagnosed "neoplasm, not being STS." Four lesions (4%) were considered nonneoplastic. Because incorrect classification of a tumor could lead to inappropriate therapeutic intervention and prognostication, the results of our study clearly illustrate the importance of revision and further diagnosis of "unclassified STSs" in dogs. PMID- 27698173 TI - Pseudomonas aeruginosa mastitis in two goats associated with an essential oil based teat dip. AB - Pseudomonas aeruginosa is an opportunistic pathogen that has been associated with mastitis in dairy animals, including goats. Often, the environmental sources of the bacteria are water-related (such as hoses and muddy pastures). Mastitis attributable to P. aeruginosa was identified in 2 goats in a small herd. Efforts were made to identify environmental sources of the pathogen. Multiple samples from the goats' environment were cultured, including water from the trough, bedding, the hose used to wash udders, and the teat dip and teat dip containers. The bacterium was isolated from the teat dip and the teat dip container. The teat dip consisted of water, liquid soap, and several drops of essential oils (including tea tree, lavender, and peppermint). This case illustrates a potential problem that may arise as a result of the use of unconventional ingredients in teat dips. The use of alternative products by goat producers is likely to increase in the future. PMID- 27698174 TI - Coinfection by Cetacean morbillivirus and Aspergillus fumigatus in a juvenile bottlenose dolphin (Tursiops truncatus) in the Gulf of Mexico. AB - A recently deceased juvenile male bottlenose dolphin (Tursiops truncatus) was found floating in the Gulf of Mexico, off Sand Key in Clearwater, Florida. At autopsy, we identified pneumonia and a focus of malacia in the right cerebrum. Cytologic evaluation of tissue imprints from the right cerebrum revealed fungal hyphae. Fungal cultures of the lung and brain yielded Aspergillus fumigatus, which was confirmed by amplification of a portion of the fungal nuclear ribosomal internal transcribed spacer 2 region sequence. Microscopic pulmonary lesions of bronchiolar epithelial cell syncytia with intracytoplasmic and intranuclear inclusions within bronchiolar epithelial cells were suggestive of Cetacean morbillivirus (CeMV) infection. The occurrence of CeMV infection was supported by positive immunohistochemical staining for morbillivirus antigen. CeMV detection was confirmed by amplification and sequencing a portion of the morbilliviral RNA dependent RNA polymerase gene from lung tissue. This case provides CeMV sequence data available from the Gulf of Mexico and underscores the need for genomic sequencing across diverse host, temporospatial, and population (i.e., single animal vs. mass mortality events) scales to improve our understanding of these globally emerging pathogens. PMID- 27698175 TI - Canine mammary minute oncocytomas with neuroendocrine differentiation associated with multifocal acinar cell oncocytic metaplasia. AB - Two solitary and minute tumors of 1 and 1.5 mm diameter were identified by microscopy in the left fourth mammary gland of a 13-year-old female Labrador Retriever dog, in addition to multiple mammary gland tumors. The former tumors were well circumscribed and were composed of small-to-large polyhedral neoplastic oncocytes with finely granular eosinophilic cytoplasm, and were arranged in solid nests separated by fine fibrovascular septa. Scattered lumina of variable sizes containing eosinophilic secretory material were evident. Cellular atypia was minimal, and no mitotic figures were visible. One tumor had several oncocytic cellular foci revealing cellular transition, with perivascular pseudorosettes consisting of columnar epithelial cells surrounding the fine vasculature. Scattered foci of mammary acinar cell hyperplasia showing oncocytic metaplasia were also observed. Immunohistochemically, the cytoplasm of neoplastic cells of the 2 microtumors showed diffuse immunoreactivity to anti-cytokeratin antibody AE1/AE3, and finely granular immunoreactivity for 60-kDa heat shock protein, mitochondrial membrane ATP synthase complex V beta subunit, and chromogranin A. One tumor also had oncocytic cellular foci forming perivascular pseudorosettes showing cellular membrane immunoreactivity for neural cell adhesion molecule. The tumors were negative for smooth muscle actin, neuron-specific enolase, vimentin, desmin, S100, and synaptophysin. Ultrastructural observation confirmed the abundant mitochondria in the cytoplasm of both neoplastic and hyperplastic cells, the former cells also having neuroendocrine granule-like electron-dense bodies. From these results, our case was diagnosed with mammary oncocytomas accompanied by neuroendocrine differentiation. Scattered foci of mammary oncocytosis might be related to the multicentric occurrence of these oncocytomas.

AB - BACKGROUND: Radial access is the preferential access route in patients undergoing diagnostic coronary angiography. We hypothesised that we could reduce hospital stay and improve patient comfort by accelerated deflation of the radial compression device (Terumo radial band). AIMS: The aim of this study was to compare accelerated pressure reduction with a standard Terumo radial band protocol with regard to local bleeding complications and reported pain scores after cardiac catheterisation. METHODS: We performed a single centre prospective randomised trial to compare accelerated care to standard care for patients undergoing diagnostic catheterisation through radial access. Patients in the accelerated care group started deflation after 1 hour, with a 2 ml/10-minute interval. Patients in the standard care group started after 2 hours with additional steps of deflation at 3 and 4 hours. RESULTS: Of the 173 analysed patients 86 received accelerated care and 87 patients standard care. A total of 19 patients had pulsatile bleeding, which occurred similarly in the two groups (standard care 11 vs. accelerated care 8, P=0.47). The time to Terumo radial band removal was on average 129 minutes shorter for accelerated care patients compared to standard care ( P<0.01). At 1 hour after Terumo radial band placement, accelerated care patients more often reported pain scores of 0 than standard care patients (89% vs. 74%, P=0.02). CONCLUSIONS: There was no increase in local bleedings in the accelerated pressure reduction of the Terumo radial band after diagnostic cardiac catheterisation, increasing patient comfort and reducing hospital stay. These findings will further facilitate the widespread implementation of radial access. PMID- 27698177 TI - Intramedullary Nailing and External Ring Fixation for Tibiotalocalcaneal Arthrodesis in Charcot Arthropathy. AB - BACKGROUND: Surgical strategies to address deformities of the ankle and hindfoot in patients with Charcot arthropathy include the use of retrograde intramedullary nails and ring fixators. The literature has not shown superiority of one technique over the other. This study presents a single surgeon's case series of Charcot arthropathy patients treated with either a ring fixator or retrograde intramedullary nail to achieve tibiotalocalcaneal arthrodesis. METHODS: We performed a retrospective analysis of 27 consecutive patients with Charcot arthropathy who underwent a tibiotalocalcaneal arthrodesis using either a retrograde intramedullary (IM) nail (n = 16 patients) or a ring fixator (RF) (n = 11 patients) by a single surgeon. We report the rates of limb salvage complications requiring secondary surgery and fusion in both groups. The patient demographics and presence of medical comorbidities known to increase the risk of surgical complications were similar between groups. The mean duration of follow up for the retrograde nail group was 3.6 years and 2.2 years for the ring fixator group. RESULTS: The mean time to discharge from the hospital after the index surgical procedure was 2.7 days for the IM group and 4.6 days for the RF group. For the patients treated with a ring fixator, the mean time to removal of the frame after the initial application was 13.3 +/- 1.8 weeks. The limb salvage rate for the RF group was 9 of 11 patients whereas it was 15 of 16 in the IM group. Complications including deep infection, hardware failure, and symptomatic nonunion requiring revision surgery were common in the IM group, with 11 of 16 patients requiring further surgery. Seven patients in the IM group required removal of the implant at a mean of 117.2 weeks after the index procedure because of the development of deep infection or nail cutout. In the RF group, only 1 patient required revision surgery. Fusion rates were similar between both groups, with 10 of 16 patients fusing in the IM group and 7 of 11 in the RF group. CONCLUSION: Use of a retrograde intramedullary rod or ring fixator resulted in high rates of successful limb salvage when used for tibiotalocalcaneal arthrodesis in patients with Charcot arthropathy. However, in this study, the need for revision surgery was more frequent in the retrograde nail group compared to the ring fixator group.

AB - BACKGROUND: Functional recovery following total ankle arthroplasty (TAA) is assessed with patient-reported metrics, but physical performance tests may allow for a more accurate assessment of patient function. We quantified correlations between patient-reported measures and physical performance tests in patients after TAA to determine the usefulness of physical performance tests in post-TAA assessment. METHODS: In total, 140 patients with end-stage ankle osteoarthritis were assessed prior to TAA and again at 12 and 24 months postoperatively. At each time point, the visual analog scale (VAS), Foot and Ankle Disability Index (FADI), American Orthopaedic Foot & Ankle Society (AOFAS), Short Musculoskeletal Function Assessment (SMFA), and Short-Form 36 (SF-36) scores were collected, as well as walking speed, Four-Square Step Test (FSST) times, and Short Physical Performance Battery (SPPB) balance scores. RESULTS: All but 1 (SF-36 general health component) of the patient-reported outcomes improved significantly from preoperative assessment to both 1 and 2 years postoperatively ( P < .001 in all cases). Walking speed, FSST times, and balance scores improved significantly across time ( P < .001 in all cases). Walking speed was moderately correlated with total SF-36 scores at both 1 and 2 years postoperatively ( P < .001 in both cases), both components of the SMFA at 1 year postoperatively ( P < .001 in both cases), and total AOFAS scores at 2 years postoperatively ( P = .001). CONCLUSION: The lack of strong correlations between the 2 sets of metrics indicates that they provide different information about a patient's recovery following TAA. Therefore, it is important to include both sets of metrics in post TAA assessments to better understand operative success and functional recovery. LEVEL OF EVIDENCE: Level IV, cohort study. PMID- 27698179 TI - Imaging of Bilateral Synchronous Testicular Tumors of Different Histologic Types and Implications for Surgical Management. AB - The clinical history and imaging and pathologic findings in 4 patients with bilateral synchronous testicular tumors of dissimilar histologic types were reviewed. All patients had a large scrotal mass on one side and a smaller nodule on the other one. The appearances of each pair of lesions were different enough to suggest that they could possibly be of different histologic types. The most important role of imaging, however, was its capability to guide the surgical approach to these patients: in 1 case, the smallest lesion was recognized as an epidermoid cyst; in 2 others a conservative approach was deemed possible, given the lesions' small volumes and peripheral locations. PMID- 27698180 TI - Use of Point-of-Care Ultrasound in the Emergency Department: Insights From the 2012 Medicare National Payment Data Set. AB - OBJECTIVES: Point-of-care ultrasound is a valuable tool with potential to expedite diagnoses and improve patient outcomes in the emergency department. However, little is known about national patterns of adoption. This study examined nationwide point-of-care ultrasound reimbursement among emergency medicine (EM) practitioners and examined regional and practitioner level variations. METHODS: Data from the 2012 Center for Medicare and Medicaid Services Fee-for-Service Provider Utilization and Payment Data include all practitioners who received more than 10 Medicare Part B fee-for-service reimbursements for any Healthcare Common Procedure Coding System code in 2012. Odds ratios (ORs) and descriptive statistics were calculated to assess relationships between ultrasound reimbursement and practice location, nearby presence of an EM residency, and time elapsed since practitioner graduation. RESULTS: Of 52,928 unique EM practitioners, 391 (0.7%) received limited ultrasound reimbursements for a total of 16,389 scans in 2012. Urban counties had an OR of 5.4 (95% confidence interval, 3.8-7.8) for receiving point-of-care ultrasound reimbursements compared to rural counties. Counties with an EM residency had an OR of 84.7 (95% confidence interval, 42.6-178.8) for reimbursement compared to counties without. The OR for receiving reimbursement was independent of medical school graduation year (P = .83); however, recent graduates performed more scans (P = .02). CONCLUSIONS: A small minority of EM practitioners received reimbursements for point-of-care ultrasound from Medicare beneficiaries. These practitioners were more likely to reside in urban and academic settings. Future efforts should assess the degree to which our findings reflect either low point-of-care ultrasound use or low rates of billing for ultrasound examinations that are performed. PMID- 27698181 TI - Completion and Sensitivity of the Second-Trimester Fetal Anatomic Survey in Obese Gravidas. AB - OBJECTIVES: To estimate the effect of maternal body mass index (BMI) on the completion of fetal anatomic surveys before 20 weeks' estimated gestational age (GA). METHODS: We conducted a retrospective cohort study of singletons undergoing standard or detailed anatomic sonographic examinations from 2006 to 2014. Patients were categorized by ranges of BMI. The primary outcomes were completion of standard and detailed anatomic surveys before 20 weeks' estimated GA. The effect of the BMI category was assessed by the chi2 test for trends and analysis of variance. RESULTS: Of 15,313 patients, 5917 (38%) were obese, and 1581 (10%) had a BMI of 40 kg/m2 or higher. Standard (P < .01) and detailed (P < .01) surveys were less likely to be completed as the BMI category increased. Suboptimal visualization of the fetal chest (P < .01), abdomen (P < .01), and extremities (P < .01) significantly contributed to the decreased standard survey completion rates. Suboptimal visualization of the fetal head (P < .01) and chest (P < .01) significantly contributed to the decreased detailed survey completion rates. There was no statistically significant difference in the sensitivity of a completed standard or detailed anatomic survey for the detection of fetal anomalies. CONCLUSIONS: An increasing BMI category was associated with decreased completion of standard and detailed anatomic surveys by 20 weeks' estimated GA. Strategies to improve early visualization of the fetal head, chest, and abdomen in obese women should be investigated to promote anomaly detection and appropriate counseling. PMID- 27698182 TI - Sonographic Measurement of the Quadriceps Muscle in Patients With Chronic Obstructive Pulmonary Disease: Functional and Clinical Implications. AB - OBJECTIVES: The purpose of this study was to determine the association between functionality as assessed by the 6-minute walking test (6MWT), maximal voluntary contraction of the quadriceps (MVCQ), and quadriceps thickness and echo intensity as measured by sonography, in patients with chronic obstructive pulmonary disease (COPD). METHODS: Maximal voluntary contraction of the quadriceps and the thickness and echo intensity of the rectus femoris and vastus intermedius were evaluated in 20 patients with COPD. Functionality was assessed by the 6MWT. Differences between the evaluated muscles were determined by the Student t test. Pearson and Spearman rank correlation coefficients were used to analyze relationships between variables of interest, according to data characteristics. Finally, multivariate regression models were applied. RESULTS: There was a positive correlation between MVCQ and rectus femoris and vastus intermedius thickness (r = 0.427; P = .030; r = 0.469; P= .018, respectively) and a negative correlation between MVCQ and rectus femoris and vastus intermedius echo intensity (r= -0.500; P= .012; r= -0.482; P= .016). No correlation was found between MVCQ and the 6MWT (r = 0.319; P = .085). Multivariate regression analysis showed that the rectus femoris echo intensity, vastus intermedius echo intensity, and vastus intermedius thickness explained 70% of the variance in the distance walked during the 6MWT. CONCLUSIONS: These results indicate that, in patients with COPD, both quadriceps force and exercise capacity are associated with quantitative (thickness) and qualitative (echo intensity) characteristics of the quadriceps. Consequently, comprehensive assessments of peripheral muscles should simultaneously include both measurements. PMID- 27698183 TI - Resistive Index Variability in Anterior Cerebral Artery Measurements During Daily Transcranial Duplex Sonography: A Predictor of Cerebrovascular Complications in Infants Undergoing Extracorporeal Membrane Oxygenation? AB - OBJECTIVES: The purpose of this study was to determine the value of resistive index (RI) variability in predicting cerebrovascular complications during extracorporeal membrane oxygenation (ECMO). METHODS: This retrospective study included 36 infants treated by ECMO. The RI was measured on daily transfontanellar duplex sonography, obtained first without fontanel compression and then after gentle compression with the transducer. The age at ECMO cannulation, sex, gestational age at birth, method of delivery, indication, and type and duration of ECMO were recorded. RESULTS: There was a statistically significant difference in RI variability in infants who developed cerebrovascular complications as opposed to those who did not (P = .002). Resistive index variability of 10% or greater on any day was associated with an increased risk for cerebrovascular complications (P = .0482; chi2 = 3.9). Variability in the first 5 days was significantly higher than on following days (P < .0001). The age at ECMO cannulation showed a significant difference, with mean +/- SD values of 1.1 +/- 0.9 days in the complications group and 2.7 +/- 2.2 days in the no complications group (P = .043). CONCLUSIONS: Resistive index variability of 10% or greater on any day had a statistically significant risk of cerebrovascular complication development. Extracorporeal membrane oxygenation cannulation at younger than 3 days conferred an increased risk of cerebrovascular complications. PMID- 27698184 TI - Physics and the Cell.

AB - The unfolded protein response is an endoplasmic reticulum stress pathway mediated by the protein chaperone glucose regulated-protein 78 (GRP78). Metabolic analysis of breast cancer cells shows that GRP78 silencing increases the intracellular concentrations of essential polyunsaturated fats, including linoleic acid. Accumulation of fatty acids is due to an inhibition of mitochondrial fatty acid transport, resulting in a reduction of fatty acid oxidation. These data suggest a novel role of GRP78-mediating cellular metabolism. We validated the effect of GRP78-regulated metabolite changes by treating tumor-bearing mice with tamoxifen and/or linoleic acid. Tumors treated with linoleic acid plus tamoxifen exhibited reduced tumor area and tumor weight. Inhibition of either GRP78 or linoleic acid treatment increased MCP-1 serum levels, decreased CD47 expression, and increased macrophage infiltration, suggesting a novel role for GRP78 in regulating innate immunity. GRP78 control of fatty acid oxidation may represent a new homeostatic function for GRP78. Cancer Res; 76(19); 5657-70. (c)2016 AACR.

AB - Global miRNA functional screens can offer a strategy to identify synthetic lethal interactions in cancer cells that might be exploited therapeutically. In this study, we applied this strategy to identify novel gene interactions in KRAS mutant cancer cells. In this manner, we discovered miR-1298, a novel miRNA that inhibited the growth of KRAS-driven cells both in vitro and in vivo Using miR TRAP affinity purification technology, we identified the tyrosine kinase FAK and the laminin subunit LAMB3 as functional targets of miR-1298. Silencing of FAK or LAMB3 recapitulated the synthetic lethal effects of miR-1298 expression in KRAS driven cancer cells, whereas coexpression of both proteins was critical to rescue miR-1298-induced cell death. Expression of LAMB3 but not FAK was upregulated by mutant KRAS. In clinical specimens, elevated LAMB3 expression correlated with poorer survival in lung cancer patients with an oncogenic KRAS gene signature, suggesting a novel candidate biomarker in this disease setting. Our results define a novel regulatory pathway in KRAS-driven cancers, which offers a potential therapeutic target for their eradication. Cancer Res; 76(19); 5777-87. (c)2016 AACR. PMID- 27698192 TI - Treg/Th17 Cell Imbalance and IL-6 Profile in Patients With Unexplained Recurrent Spontaneous Abortion. AB - Regulatory T cells (Treg) and T helper 17 cells (Th17) are 2 distinct subsets of CD4+ T cells, which are mutually antagonistic in the immune response. Recently, dysregulation of these 2 cell subsets have been described in the pathogenesis of unexplained recurrent spontaneous abortion (URSA). The purpose of this study was to investigate whether the Treg/Th17 balance was perturbed in URSA patients and to explore contributing factors. We found that the proportion of Treg cells and expression of forkhead box P3 (Foxp3) messenger RNA (mRNA) were significantly lower in URSA patients than in healthy controls. However, the proportion of Th17 cells and expression of retinoid-related orphan nuclear receptor-gammat (ROR gammat) mRNA were higher in URSA patients than in controls, revealing inverse correlation with Treg. The ratio of Treg/Th17 and Foxp3/ROR-gammat decreased in patients with URSA compared to healthy controls. The serum levels of interleukin (IL)-6 and IL-17A were significantly higher, whereas IL-10 was lower in URSA patients compared with controls, and the level of IL-6 showed a positive correlation with Th17, ROR-gammat and inverse correlation with Treg, Foxp3. The present study indicated that an imbalance between Treg and Th17 cells might be implicated in the pathogenesis of URSA and this seems to relate to elevation in serum IL-6 level. PMID- 27698193 TI - Estimating discharge dates using routinely collected data: improving the preparedness of parents of preterm infants for discharge home. AB - The length of stay for moderately preterm infants has progressively become shorter in the UK in recent years but staff still commonly inform parents that their baby will go home around their estimated date of delivery (EDD). Parents need as much notice as possible to prepare for the discharge of their baby, and to gain the necessary skills and knowledge to care for their infant safely. We report the use of routinely collected neonatal data to develop and implement a simple centile chart for date of discharge from hospital, which allows staff and parents to predict the likely discharge date more accurately for preterm infants, most of whom now go home more than 3 weeks before their EDD. This information allows better and timelier planning for discharge of such infants, by parents and staff.

PMID- 27698195 TI - Job insecurity and risk of diabetes: a meta-analysis of individual participant data. AB - BACKGROUND: Job insecurity has been associated with certain health outcomes. We examined the role of job insecurity as a risk factor for incident diabetes. METHODS: We used individual participant data from 8 cohort studies identified in 2 open-access data archives and 11 cohort studies participating in the Individual Participant-Data Meta-analysis in Working Populations Consortium. We calculated study-specific estimates of the association between job insecurity reported at baseline and incident diabetes over the follow-up period. We pooled the estimates in a meta-analysis to produce a summary risk estimate. RESULTS: The 19 studies involved 140 825 participants from Australia, Europe and the United States, with a mean follow-up of 9.4 years and 3954 incident cases of diabetes. In the preliminary analysis adjusted for age and sex, high job insecurity was associated with an increased risk of incident diabetes compared with low job insecurity (adjusted odds ratio [OR] 1.19, 95% confidence interval [CI] 1.09-1.30). In the multivariable-adjusted analysis restricted to 15 studies with baseline data for all covariates (age, sex, socioeconomic status, obesity, physical activity, alcohol and smoking), the association was slightly attenuated (adjusted OR 1.12, 95% CI 1.01-1.24). Heterogeneity between the studies was low to moderate (age- and sex-adjusted model: I2 = 24%, p = 0.2; multivariable-adjusted model: I2 = 27%, p = 0.2). In the multivariable-adjusted analysis restricted to high-quality studies, in which the diabetes diagnosis was ascertained from electronic medical records or clinical examination, the association was similar to that in the main analysis (adjusted OR 1.19, 95% CI 1.04-1.35). INTERPRETATION: Our findings suggest that self-reported job insecurity is associated with a modest increased risk of incident diabetes. Health care personnel should be aware of this association among workers reporting job insecurity. PMID- 27698199 TI - Realizing the vision of patient-relevant clinical research.

PMID- 27698205 TI - A reverse genetics cell-based evaluation of genes linked to healthy human tissue age. AB - We recently developed a binary (i.e., young vs. old) classifier using human muscle RNA profiles that accurately distinguished the age of multiple tissue types. Pathway analysis did not reveal regulators of these 150 genes, so we used reverse genetics and pharmacologic methods to explore regulation of gene expression. Using small interfering RNA, well-studied age-related factors (i.e., rapamycin, resveratrol, TNF-alpha, and staurosporine), quantitative real-time PCR and clustering analysis, we studied gene-gene interactions in human skeletal muscle and renal epithelial cells. Individual knockdown of 10 different age genes yielded a consistent pattern of gene expression in muscle and renal cells, similar to in vivo. Potential epigenetic interactions included HIST1H3E knockdown, leading to decreased PHF19 and PCDH9, and increased ICAM5 in muscle and renal cells, while ICAM5 knockdown reduced HIST1H3E expression. Resveratrol, staurosporine, and TNF-alpha significantly regulated the in vivo aging genes, while only rapamycin perturbed the healthy-age gene expression signature in a manner consistent with in vivo. In vitro coordination of gene expression for this in vivo tissue age signature indicates a degree of direct coordination, and the observed link with mTOR activity suggests a direct link between a robust biomarker of healthy neuromuscular age and a major axis of life span in model systems.-Crossland, H., Atherton, P.

AB - Objective To perform a meta-analysis to evaluate studies investigating the association between ATG16L1 gene polymorphism and Crohn's disease. Methods PubMed, Embase and Web of Science databases were searched for all studies focusing on the association of ATG16L1 and Crohn's disease. Combined odds ratios with 95% confidence intervals were calculated for four genetic models (allelic model: G allele versus A allele; additive model: GG versus AA; dominant model: GA + GG versus AA; recessive model: GG versus GA + AA) using either a random effects or fixed effects model. Results A total of 47 case-control studies involving 18 638 cases and 30 181 controls were included in the final meta-analysis. There was a significant association between ATG16L1 and Crohn's disease for all four genetic models. Significant associations were also shown in subgroup analyses when stratified by study design (population- or hospital-based). Conclusion In this meta-analysis, the ATG16L1 genotype was significantly associated with the risk of developing Crohn's disease. PMID- 27698207 TI - High-flow nasal cannula therapy for adult patients. AB - High-flow nasal cannula (HFNC) oxygen therapy has several physiological advantages over traditional oxygen therapy devices, including decreased nasopharyngeal resistance, washing out of the nasopharyngeal dead space, generation of positive pressure in the pharynx, increasing alveolar recruitment in the lungs, humidification of the airways, increased fraction of inspired oxygen and improved mucociliary clearance. Recently, the use of HFNC in treating adult critical illness patients has significantly increased, and it is now being used in many patients with a range of different disease conditions. However, there are no established guidelines to direct the safe and effective use of HFNC for these patients. This review article summarizes the available published literature on the positive physiological effects, mechanisms of action, and the clinical applications of HFNC, compared with traditional oxygen therapy devices. The available literature suggests that HFNC oxygen therapy is an effective modality for the early treatment of critically adult patients. PMID- 27698208 TI - Regulation of steroidogenesis in fetal bovine ovaries: differential effects of LH and FSH. AB - In cattle, primordial follicles form before birth. Fetal ovarian capacity to produce progesterone and estradiol is high before follicle formation begins and decreases around the time follicles first appear (around 90 days of gestation). However, mechanisms that regulate steroid production during this time remain unclear. We hypothesized that LH stimulates progesterone and androgen production and that FSH stimulates aromatization of androgens to estradiol. To test this, we cultured pieces from fetal bovine ovaries for 10 days without or with exogenous hormones and then measured the accumulation of steroids in the culture medium by RIA. LH (100 ng/mL) alone increased the accumulation of progesterone, androstenedione, testosterone and estradiol. FSH (100 ng/mL) alone increased both progesterone and estradiol accumulation, but had no effect on androgens. Exogenous testosterone (0.5 uM) alone greatly increased estradiol accumulation and the combination of testosterone + FSH, but not testosterone + LH, increased estradiol relative to testosterone alone. Interestingly, exogenous testosterone and estradiol decreased progesterone accumulation in a dose-dependent manner. Because the highest dose of estradiol (0.5 uM) decreased progesterone accumulation, but increased both pregnenolone and androstenedione in the same cultures, endogenous estradiol may be a paracrine regulator of steroid synthesis. Together, these results confirm our initial hypotheses and indicate that LH stimulates androgen production in fetal bovine ovaries via the Delta5 pathway, whereas FSH stimulates aromatization of androgens to estradiol. These results are consistent with the two-cell, two-gonadotropin model of estradiol production by bovine preovulatory follicles, which suggests that the mechanisms regulating ovarian steroid production are established during fetal life. PMID- 27698209 TI - Assessing the Effectiveness of a School-Based Dental Clinic on the Oral Health of Children Who Lack Access to Dental Care. AB - This program evaluation examines the effectiveness of a school-based dental clinic. A repeated-measures design was used to longitudinally examine secondary data from participants ( N = 293). Encounter intensity was developed to normalize data. Multivariate analysis of variance and Kruskal-Wallis test were used to investigate the effect of encounter intensity on the change in decay, restorations, and treatment urgency. A Pearson's correlation was used to measure the strengths of association. Encounter intensity had a statistically significant effect on change in decay ( p = .005), restorations ( p = .000), and treatment urgency ( p = .001). As encounter intensity increased, there was a significant association with the decrease in decay (-.167), increase in restorations (.221), and reduction in referral urgency (-.188). Incorporating dental care into a school-based health center resulted in improved oral health in underserved children while overcoming barriers that typically restrict access. The collaboration of school nurses with the school-based dental clinic was an important element for maximizing student access to dental care. PMID- 27698210 TI - Research Priorities for School Nursing in the United Arab Emirates (UAE). AB - School nurses are challenged with more children having complex conditions, who are now surviving into school age. This is paralleled by a shift in focus of health systems toward primary care, and national efforts to develop the health care services, especially those offered to vulnerable populations. Being at the forefront of this change, school nurses in United Arab Emirates (UAE) are finding themselves under pressure to adapt to and facilitate these changes both by improving their practice and by contributing to its underpinning evidence. A cross-sectional design was used in this study in which 370 school nurses participated, identifying 11 research priorities. The three most important, as ranked by participants, were management of children with complex health-care needs; nutrition, obesity, and lifestyle issues of schoolchildren; and managing illnesses, injuries, and emergencies in schools and provision of medical support. These priorities should direct future research activities in the field. PMID- 27698213 TI - Suicide and the economic situation in Europe: are we experiencing the development of a 'reverse stigma'? AB - The prevailing picture in both the scientific literature and mass media is that the increase in unemployment acts as a generic risk factor on the entire population and increases the rate of suicide, suggesting that the socioeconomic environment is the determining factor and measures to improve it are the most suitable in the struggle to reduce the number of suicides. As a result, 'horizontal' actions targeting the general population are proposed rather than 'vertical' actions that target specific vulnerable groups. This is not only a mistake but it also constitutes a kind of 'reverse' stigma which deprives mental health patients of their right to receive special and targeted benefits, interventions and care, and deprives mental healthcare of valuable resources. PMID- 27698211 TI - Menthol decreases oral nicotine aversion in C57BL/6 mice through a TRPM8 dependent mechanism. AB - BACKGROUND: Nicotine is a major oral irritant in smokeless tobacco products and has an aversive taste. Mentholated smokeless tobacco products are highly popular, suggesting that menthol increases their palatability and may facilitate initiation of product use. While menthol is known to reduce respiratory irritation by tobacco smoke irritants, it is not known whether this activity extends to oral nicotine and its aversive effects. STUDY DESIGN: The two-bottle choice drinking assay was used to characterise aversion and preference in C57BL/6 mice to a range of menthol concentrations (10-200 ug/mL). Then, effects of menthol on oral nicotine aversion were determined. Responses were compared with those in mice deficient in the cold/menthol receptor, TRPM8, expressed in trigeminal sensory neurons innervating the oral cavity. RESULTS: Mice showed aversion to menthol concentrations of 100 ug/mL and above. When presented with a highly aversive concentration of nicotine (200 ug/mL), mice preferred solutions with 50 or 100 ug/mL menthol added over nicotine alone. In contrast to wild-type mice, Trpm8-/- showed a strong aversion to mentholated (100 ug/mL) nicotine (200 ug/mL) and preferred nicotine alone. Trpm8-/- mice show aversion to lower concentrations of menthol than wild-type mice. CONCLUSIONS: Oral menthol can reduce the aversive effects of oral nicotine and, at higher concentrations, acts as an irritant by itself. Menthol's effects in relation to nicotine require TRPM8, the cool temperature sensing ion channel that activates analgesic and counterirritant mechanisms. These mechanisms may underlie preference for menthol containing smokeless tobacco products and may facilitate initiation of product use.

AB - PURPOSE: We assessed public support for required water access in schools and parks and perceived safety and taste of water in these settings to inform efforts to increase access to and consumption of tap water. DESIGN: Cross-sectional survey of the US public collected from August to November 2011. SETTING: Random digit-dialed telephone survey. PARTICIPANTS: Participants (n = 1218) aged 17 and older from 1055 US counties in 46 states. MEASURES: Perceived safety and taste of water in schools and parks as well as support for required access to water in these settings. ANALYSIS: Survey-adjusted perceived safety and taste as well as support for required access were estimated. RESULTS: There was broad support for required access to water throughout the day in schools (96%) and parks (89%). Few participants believed water was unsafe in schools (10%) or parks (18%). CONCLUSION: This study provides evidence of public support for efforts to increase access to drinking water in schools and parks and documents overall high levels of perceived taste and safety of water provided in these settings. PMID- 27698228 TI - Transcriptional Regulation of CYP2D6 Expression. AB - CYP2D6-mediated drug metabolism exhibits large interindividual variability. Although genetic variations in the CYP2D6 gene are well known contributors to the variability, the sources of CYP2D6 variability in individuals of the same genotype remain unexplained. Accumulating data indicate that transcriptional regulation of CYP2D6 may account for part of CYP2D6 variability. Yet, our understanding of factors governing transcriptional regulation of CYP2D6 is limited. Recently, mechanistic studies of increased CYP2D6-mediated drug metabolism in pregnancy revealed two transcription factors, small heterodimer partner (SHP) and Kruppel-like factor 9, as a transcriptional repressor and an activator, respectively, of CYP2D6. Chemicals that increase SHP expression (e.g., retinoids and activators of farnesoid X receptor) were shown to downregulate CYP2D6 expression in the humanized mice as well as in human hepatocytes. This review summarizes the series of studies on the transcriptional regulation of CYP2D6 expression, potentially providing a basis to better understand the large interindividual variability in CYP2D6-mediated drug metabolism. PMID- 27698230 TI - Subclinical ischemic events in patients undergoing carotid artery stent placement: comparison of proximal and distal protection techniques. AB - OBJECTIVE: To determine the relative effectiveness of proximal and distal protection in prevention of cerebral ischemic events during carotid artery stent (CAS) placement using diffusion-weighted MRI (DW-MRI). METHODS: We analyzed data from patients who had undergone DW-MRI before and within 24 hours of CAS for symptomatic internal carotid artery (ICA) stenosis (with last ischemic events within 3 months). The study was performed prospectively; patients were not randomized, and were treated either with a proximal balloon occlusion system (Mo.Ma; Invatec, Roncadelle, Italy) or filter-type distal protection device (Spider device; ev3, Plymouth, Minnesota, USA). RESULTS: Of the 45 patients (mean age+/-SD: 66.9+/-9.8 years; 73.3% were men) who underwent CAS, 19 had proximal protection and 26 distal protection. New ischemic lesions were detected in 26/45 patients on DW-MRI scans obtained within 24 hours after CAS. The proportion of patients with new lesions on DW-MRI at 24 hours was not different between the two groups (47.4% vs 65.4% for proximal and distal protection, respectively). The mean number of new ischemic lesions on post-CAS DW-MRI was non-significantly higher in patients who underwent CAS with distal protection (2.80+/-3.54 for proximal protection vs 4.96+/-5.11 for distal protection; p=0.12). The proportion of patients with new lesions >1 cm did not differ between the two groups (5.3% for proximal protection vs 11.5% for distal protection; p=0.62). There was no difference in the rates of ischemic stroke between patients who underwent CAS treatment using proximal and distal protection (5.3% vs 7.7%; p=1.000). CONCLUSIONS: We found a relatively high rate of new ischemic lesions in patients undergoing CAS with cerebral protection. There was no difference in the proportion of patients with new lesions between patients treated using distal protection and those treated using proximal protection. PMID- 27698229 TI - Stent-assisted coiling of cerebrovascular aneurysms: experience at a large tertiary care center with a focus on predictors of recurrence. AB - BACKGROUND: Stent-assisted coiling is commonly used to treat wide-necked and fusiform cerebral aneurysms. We evaluated our institutional experience with stent assisted coiling of cerebral aneurysms to elucidate potential risk factors for recurrence. METHODS: A retrospective analysis of patients undergoing stent assisted coiling of cerebral aneurysms from 2005 to 2012 resulted in 122 patients with 122 aneurysms. Demographic, peri-procedural, medical comorbidity, and follow up data were collected. Primary outcomes of interest were procedural safety, efficacy, and aneurysm recurrence. Univariate and multivariate logistic regression and chi2 tests determined the statistical significance of the risk factors. RESULTS: All 122 stent-assisted coiling procedures led to satisfactory obliteration of the aneurysm (3.3% complication rate). Twenty-one (17.2%) patients experienced recurrence at average follow-up of 297 days. Fifteen (71.4%) clinically significant recurrences required retreatment. Eleven of 30 (36.7%) procedures using Enterprise stents had recurrence compared with only 10 of 92 (10.9%) procedures using Neuroform stents (p=0.001). Average coiling packing density (PD) was 20.3% with Enterprise stents and 22.5% with Neuroform stents (p=0.8). In multivariate logistic regression, recurrences requiring recoiling were significantly associated with Enterprise stents (OR 8.57, 95% CI 1.97 to 37.19; p=0.004), females (OR 0.19, 95% CI 0.04 to 1.00; p=0.05), and postoperative dextran use (OR 8.42, 95% CI 1.40 to 50.58; p=0.02). Aneurysms with <20% PD were more likely to have a clinically significant recurrence than aneurysms with >20% PD (19% vs 5.1%; p=0.02). CONCLUSIONS: Stent-assisted coiling for wide-necked cerebral aneurysms has a high therapeutic success rate with low procedure-related morbidity and mortality. Clinically significant recurrences may occur more frequently with Enterprise stents, in aneurysms with low PD, and with post-procedural dextran use. PMID- 27698231 TI - A new index for the assessment of transverse sinus stenosis for diagnosing idiopathic intracranial hypertension. AB - BACKGROUND AND PURPOSE: To assess the role of MR venography (MRV) for detecting transverse sinus stenosis, to determine the importance of this finding in idiopathic intracranial hypertension (IIH), and to propose an index that contributes to this diagnosis. MATERIALS AND METHODS: We retrospectively assessed consecutive intracranial MRV of patients aged >18 years diagnosed with IIH according to the diagnostic criteria, between January 2010 and July 2012. The assessments were randomly analyzed by three radiologists. Stenoses in the right and left transverse sinuses were independently classified according to the following scale: 0, normal; 1, stenosis <33%; 2, stenosis 33-66%; 3, stenosis >66%; and 4, hypoplasia or agenesis. We established an index based on multiplication of the stenosis scale values for each transverse sinus. A point and range estimate of the sensitivity, specificity, and the area under the receiver operating characteristic curve was performed to obtain cut-off points to differentiate between controls and patients. RESULTS: 63 individuals were included in this study: 32 (50.8%) diagnosed with IIH (31 (96.9%) women and 1 (3.1%) man) and 31 (49.2%) controls. According to all of the examiners, the IIH group showed a higher degree of stenosis than the control group. Index values >=4 for a diagnosis of IIH had a sensitivity and specificity of 94.7% and 93.5%, respectively. CONCLUSIONS: MRV should be used to assess patients with suspected IIH, and bilateral transverse sinus stenosis should be considered for the diagnosis. The stenosis classifying index proposed here is a fast and accessible method for diagnosing IIH. PMID- 27698232 TI - Optimized CRISPR-Cas9 System for Genome Editing in Zebrafish. AB - This protocol describes how to generate and genotype mutants using an optimized CRISPR-Cas9 genome-editing system in zebrafish (CRISPRscan). Because single guide RNAs (sgRNAs) have variable efficiency when targeting specific loci, our protocol starts by explaining how to use the web tool CRISPRscan to design highly efficient sgRNAs. The CRISPRscan algorithm is based on the results of an integrated analysis of more than 1000 sgRNAs in zebrafish, which uncovered highly predictive factors that influence Cas9 activity. Next, we describe how to easily generate sgRNAs in vitro, which can then be injected in vivo to target specific loci. The use of highly efficient sgRNAs can lead to biallelic mutations in the injected embryos, causing lethality. We explain how targeting Cas9 to the germline increases viability by reducing somatic mutations. Finally, we combine two methods to identify F1 heterozygous fish carrying the desired mutations: (i) Mut-Seq, a method based on high-throughput sequencing to detect F0 founder fish; and (ii) a polymerase chain reaction-based fragment analysis method that identifies F1 heterozygous fish characterized by Mut-Seq. In summary, this protocol includes the steps to generate and characterize mutant zebrafish lines using the CRISPR-Cas9 genome engineering system. PMID- 27698233 TI - Detection of DNA Fragmentation in Apoptotic Cells by TUNEL. AB - Degradation of DNA into oligonucleosomal-sized fragments is a unique event in apoptosis that is orchestrated by caspase-activated DNase. Traditionally, this event is observed by resolving cellular DNA by gel electrophoresis, which results in a characteristic "ladder" pattern. However, this technique is time-consuming and cannot be used to quantitate the number of apoptotic cells in a sample. Terminal dUTP nick-end labeling (TUNEL) of fragmented DNA allows researchers to identify DNA fragmentation at the single-cell level. This method involves the specific addition of fluorescently labeled UTP to the 3'-end of the DNA fragments by terminal deoxynucleotidyl transferase. The TUNEL assay is both fast and sensitive. Here, we describe a protocol in which cells are treated with TUNEL reagent and counterstained with Hoechst 33342. In contrast to TUNEL, which only stains apoptotic cells, Hoechst 33342 stains the DNA of all cells. PMID- 27698234 TI - Measuring the DNA Content of Cells in Apoptosis and at Different Cell-Cycle Stages by Propidium Iodide Staining and Flow Cytometry. AB - All cells are created from preexisting cells. This involves complete duplication of the parent cell to create two daughter cells by a process known as the cell cycle. For this process to be successful, the DNA of the parent cell must be faithfully replicated so that each daughter cell receives a full copy of the genetic information. During the cell cycle, the DNA content of the parent cell increases as new DNA is synthesized (S phase). When there are two full copies of the DNA (G2/M phase), the cell splits to form two new cells (G0/G1 phase). As such, cells in different stages of the cell cycle have different DNA contents. The cell cycle is tightly regulated to safeguard the integrity of the cell and any cell that is defective or unable to complete the cell cycle is programmed to die by apoptosis. When this occurs, the DNA is fragmented into oligonucleosomal sized fragments that are disposed of when the dead cell is removed by phagocytosis. Consequently apoptotic cells have reduced DNA content compared with living cells. This can be measured by staining cells with propidium iodide (PI), a fluorescent molecule that intercalates with DNA at a specific ratio. The level of PI fluorescence in a cell is, therefore, directly proportional to the DNA content of that cell. This protocol describes the use of PI staining to determine the percentage of cells in each phase of the cell cycle and the percentage of apoptotic cells in a sample.

AB - Functional protein microarrays allow fast, straightforward, and efficient high throughput screening of protein-protein interactions. The microarray approach has outpaced other interaction methods, such as yeast two-hybrid screens, in part because of the vast amounts of information that can be obtained during a single assay. This protocol describes how to perform a binding assay for a protein of interest using a proteome microarray composed of thousands of functional, recombinant proteins adhered to a microchip. PMID- 27698236 TI - Characterization of RNA-Binding Proteins Using Protein Microarrays. AB - RNA-binding proteins (RBPs), along with target RNA, play a vital role in the regulation of cellular processing and are especially important in gene transcription and posttranscriptional regulation. Here, we present a high throughput method for rapid identification of RBPs for a given RNA using protein microarray technology. This protocol includes preparation of Cy5-labeled RNA probes, probe denaturing and refolding, and an RNA-binding assay as performed on a yeast protein microarray. PMID- 27698237 TI - Characterization of Lipid-Protein Interactions Using Nonquenched Fluorescent Liposomal Nanovesicles and Yeast Proteome Microarrays. AB - Studying lipid-protein interactions is central to understanding lipid signaling, a key regulatory system in cells. To better identify lipid-binding proteins, we developed a nonquenched fluorescent (NQF) liposome that is able to carry both fluorescent molecules and a lipid of interest. By combining the strength of NQF liposomes with protein microarray technology, the method presented here facilitates high-throughput screening of lipid-protein interactions. This protocol describes how to prepare NQF liposomes and apply the fabricated liposomes to yeast proteome microarrays. PMID- 27698238 TI - Posttranslational Modification Assays on Functional Protein Microarrays. AB - Protein microarray technology provides a straightforward yet powerful strategy for identifying substrates of posttranslational modifications (PTMs) and studying the specificity of the enzymes that catalyze these reactions. Protein microarray assays can be designed for individual enzymes or a mixture to establish connections between enzymes and substrates. Assays for four well-known PTMs phosphorylation, acetylation, ubiquitylation, and SUMOylation-have been developed and are described here for use on functional protein microarrays. Phosphorylation and acetylation require a single enzyme and are easily adapted for use on an array. The ubiquitylation and SUMOylation cascades are very similar, and the combination of the E1, E2, and E3 enzymes plus ubiquitin or SUMO protein and ATP is sufficient for in vitro modification of many substrates. PMID- 27698239 TI - Preparation of Yeast DNA Sequencing Libraries. AB - This protocol provides a detailed description of how to prepare a DNA sequencing library from yeast genomic DNA for use with the Illumina sequencing platform. This method does not require purchase of Illumina kits for library preparation but instead employs specific reagents purchased largely from New England BioLabs, which significantly reduces the cost of library preparation. Although we assume here that users intend to generate libraries with ~400-bp insert sizes for paired end sequencing, it is relatively straightforward to modify the shearing and size selection steps for longer or shorter inserts. PMID- 27698241 TI - Reporter Gene Silencing Assays in Fission Yeast. AB - Reporter gene silencing assays provide a facile method for assessing the function of heterochromatin in Schizosaccharomyces pombe They use strains containing auxotrophic markers (commonly ura4+ or ade6+) located within a heterochromatic region. Transcriptional silencing of these reporters can be assessed by plating serial dilutions of cells onto minimal agar. In addition, silencing of ura4+ renders cells resistant to 5-fluoroorotic acid (5-FOA) and ade6+ silencing results in red colony color on adenine-limiting agar. Various reporters for each of the major heterochromatic domains (telomeres, centromeres, and the mating type locus) are available and, importantly, transcriptional silencing is correlated with the proper function of these regions. PMID- 27698242 TI - Analysis of Schizosaccharomyces pombe Heterochromatin-Associated Short Interfering RNAs. AB - An important aspect of RNAi-mediated heterochromatin assembly is the production of short interfering RNAs (siRNAs) in cis at the heterochromatic target. These populations of small RNAs (20-30 nt) can be detected via northern blot analysis with radiolabeled RNA probes corresponding to the siRNAs. Most heterochromatin associated siRNAs originate from both strands of the pericentromeric dg and dh repeats. Thus, production of RNA probes by in vitro transcription utilizes a DNA template with sequences corresponding to either dg or dh repeats. Alternatively, radiolabeled DNA probes, which are somewhat easier to prepare, may be used. A control probe against a small RNA, such as a tRNA, may also be prepared for loading. More recently genome-scale analysis using next-generation sequencing platforms has enabled the detection of rare siRNAs at sites other than the major heterochromatin domains. This protocol describes procedures for the extraction of small RNAs from Schizosaccharomyces pombe and their detection by northern blot analysis. PMID- 27698240 TI - Combining Optogenetics and Electrophysiology to Analyze Projection Neuron Circuits. AB - A set of methods is described for channelrhodopsin-2 (ChR2)-based synaptic circuit analysis that combines photostimulation of virally transfected presynaptic neurons' axons with whole-cell electrophysiological recordings from retrogradely labeled postsynaptic neurons. The approach exploits the preserved photoexcitability of ChR2-expressing axons in brain slices and can be used to assess either local or long-range functional connections. Stereotaxic injections are used both to express ChR2 selectively in presynaptic axons of interest (using rabies virus [RV] or adeno-associated virus [AAV]) and to label two types of postsynaptic projection neurons of interest with fluorescent retrograde tracers. In brain slices, tracer-labeled postsynaptic neurons are targeted for whole-cell electrophysiological recordings, and synaptic connections are assessed by sampling voltage or current responses to light-emitting diode (LED) photostimulation of ChR2-expressing axons. The data are analyzed to estimate the relative amplitude of synaptic input and other connectivity parameters. Pharmacological and electrophysiological manipulations extend the versatility of the basic approach, allowing the dissection of monosynaptic versus disynaptic responses, excitatory versus inhibitory responses, and more. The method enables rapid, quantitative characterization of synaptic connectivity between defined pre and postsynaptic classes of neurons.

Yields vary between 100 and 5 ug of DNA, depending on the copy number of the plasmid. Miniprep DNA is sufficiently pure for use as a substrate or template in many in vitro enzymatic reactions. However, further purification is required if the plasmid DNA is used as the substrate in sequencing reactions. PMID- 27698244 TI - High-Throughput Yeast Strain Sequencing. AB - The original yeast genome sequencing project was a monumental task, spanning several years, which resulted in the first sequenced eukaryotic genome. The 12 Mbp reference sequence was generated from yeast strain S288c and was of extremely high quality. In the years since it was published, sequencing technology has advanced apace, such that it is within the reach of most labs to sequence yeast strains of interest almost as a matter of standard practice, either via core facilities at their institution or through commercial sequencing services. Because of the availability of the high-quality reference sequence (which itself has received approximately 1500 updates derived from high-throughput sequencing data), reliable identification of differences between a strain of interest and the reference is relatively straightforward, at least for the nonrepetitive regions of the genome. In this introduction, we describe current high-throughput sequencing technology and methods for analysis of the resulting data. PMID- 27698245 TI - Protein Microarrays: Flexible Tools for Scientific Innovation. AB - Protein microarrays have emerged as a powerful tool for the scientific community, and their greatest advantage lies in the fact that thousands of reactions can be performed in a parallel and unbiased manner. The first high-density protein microarray, dubbed the "yeast proteome array," consisted of approximately 5800 full-length yeast proteins and was initially used to identify protein-lipid interactions. Further assays were subsequently developed to allow measurement of protein-DNA, protein-RNA, and protein-protein interactions, as well as four well known posttranslational modifications: phosphorylation, acetylation, ubiquitylation, and SUMOylation. In this introduction, we describe the advent of high-density protein microarrays, as well as current methods for assessing a wide variety of protein interactions and posttranslational modifications. PMID- 27698246 TI - Optimization Strategies for the CRISPR-Cas9 Genome-Editing System. AB - The CRISPR-Cas9 system uncovered in bacteria has emerged as a powerful genome editing technology in eukaryotic cells. It consists of two components-a single guide RNA (sgRNA) that directs the Cas9 endonuclease to a complementary DNA target site. Efficient targeting of individual genes requires highly active sgRNAs. Recent efforts have made significant progress in understanding the sequence features that increase sgRNA activity. In this introduction, we highlight advancements in the field of CRISPR-Cas9 targeting and discuss our web tool CRISPRscan, which predicts the targeting activity of sgRNAs and improves the efficiency of the CRISPR-Cas9 system for in vivo genome engineering. PMID- 27698247 TI - The impact of multiple sclerosis severity on health state utility values: Evidence from Australia. AB - BACKGROUND: The measurement of health state utility values (HSUVs) for a representative sample of Australian people with multiple sclerosis (MS) has not previously been performed. OBJECTIVES: Our main aim was to quantify the HSUVs for different levels of disease severities in Australian people with MS. METHOD: HSUVs were calculated by employing a 'judgement-based' method that essentially creates EQ-5D-3L profiles based on WHOQOL-100 responses and then applying utility weights to each level in each dimension. A stepwise linear regression was used to evaluate the relationship between HSUVs and disease severity, classified as mild (Expanded Disability Status Scale (EDSS) levels: 0-3.5), moderate (EDSS levels: 4 6) and severe (EDSS levels: 6.5-9.5). RESULTS: Mean HSUV for all people with MS was 0.53 (95% confidence interval (CI): 0.52-0.54). Utility decreased with increasing disease severity: 0.61 (95% CI: 0.60-0.62), 0.51 (95% CI: 0.50-0.52) and 0.40 (95% CI: 0.38-0.43) for mild, moderate and severe disease, respectively. Adjusted differences in mean HSUV between the three severity groups were statistically significant. CONCLUSION: For the first time in Australia, we have quantified the impact of increasing severity of MS on health utility of people with MS. The HSUVs we have generated will be useful in further health economic analyses of interventions that slow progression of MS. PMID- 27698249 TI - Prevalence of Shiga toxin-producing and enteropathogenic Escherichia coli marker genes in diarrhoeic stools in a New Zealand catchment area. AB - BACKGROUND: Shiga toxin-producing (STEC) and enteropathogenic (EPEC) Escherichia coli are gastrointestinal pathogens causing diarrhoeal and extraintestinal disease. Due to lack of EPEC screening and use of Sorbitol-MacConkey (SMAC) agar in faecal screening, the true prevalence of EPEC and non-O157 STEC in New Zealand diarrhoeal cases is unknown. METHODS: Diarrhoeic stools sourced from Dunedin hospital were pre-enriched, DNA extracted with Chelex-100 resin and screened using a multiplex TaqMan quantitative PCR assay amplifying stx1, sxt2 and EPEC (eae) gene markers. RESULTS: Of the 522 diarrhoeic samples surveyed, 8 (1.53%) were PCR positive for stx1/stx2 and 23 (4.41%) were positive for eae. Six (75%) of the stx+ samples were uncommon non-O157 serotypes, and the remainder were found to be positive for both O103 and O157 STEC somatic antigens. CONCLUSIONS: Results revealed shortcomings in current screening protocols for pathogenic E. coli; SMAC is not sufficiently discriminatory to detect emergent STEC serotypes and EPEC likely has an unappreciated role in cases of diarrhoea in New Zealand.

PMID- 27698248 TI - In vivo detection of connectivity between cortical and white matter lesions in early MS. AB - BACKGROUND: The relationship between cortical lesions (CLs) and white matter lesions (WMLs) in multiple sclerosis (MS) is poorly understood. Pathological studies support a topographical association between CLs and underlying subcortical WMLs and suggest CLs may play a role in both disease initiation and progression. We hypothesized that cortical MS lesions are physically connected to white matter MS lesions via axonal connections. OBJECTIVE: To assess the presence of CL-WML connectivity utilizing novel magnetic resonance imaging (MRI) methodology. METHODS: In all, 28 relapsing-remitting MS patients and 25 controls received 3 T MRI scans, including double inversion recovery (DIR) for CL detection coupled with diffusion tensor imaging (DTI). CL and WML maps were created, and DTI was used to calculate inter-lesional connectivity and volumetric connectivity indices. RESULTS: All patients showed inter-lesional WML connectivity (median 76% of WMLs connected to another WML; interquartile range (IQR), 58%-88%). On average, 52% of detected CLs per patient were connected to at least one WML (IQR, 42%-71%). Volumetric connectivity analysis showed significantly elevated cortical lesion ratios in MS patients (median, 2.3; IQR, 1.6-3.3) compared to null MS and healthy control datasets ( p < 0.001). CONCLUSION: These findings provide strong evidence of inter-lesional connectivity between CLs and WMLs, supporting our hypothesis of intrinsic CL-WML connectivity.

AB - Increased expression levels of KCNJ3 have been correlated with lymph node metastases and poor prognosis in patients with breast cancer, suggesting a prognostic role of KCNJ3 We aimed to establish protocols for the detection of KCNJ3 in formalin-fixed, paraffin-embedded (FFPE) breast cancer tissue. Several antibodies were tested for sensitivity and specificity by western blot, followed by optimisation of the immunohistochemistry (IHC) procedure and establishment of KCNJ3 mRNA in situ hybridisation (ISH). Methods were validated by processing 15 FFPE breast cancer samples for which microarray data were available. Spearman's rank correlation analysis resulted in borderline significant correlation for IHC versus ISH (rS: 0.625; p<0.05) and IHC versus microarray (rS: 0.668; p<0.01), but in significant correlation for ISH versus microarray (rS: 0.861; p<0.001). The ISH method was superior to IHC, regarding robustness, sensitivity and specificity and will aid to further study expression levels of KCNJ3 in both malignant and physiological conditions.

PMID- 27698252 TI - Secretory leukocyte protease inhibitor promising protective roles in obesity associated atherosclerosis. AB - Secretory leukocyte protease inhibitor (SLPI), a serine protease inhibitor, which was most commonly examined in mucosal fluids such as saliva, is a versatile molecule and plays non-redundant roles. In addition to its anti-protease activity, SLPI has been shown to express anti-bacterial, anti-viral, anti-fungal, and anti-inflammatory properties as well as participating in innate and adaptive immune responses, most of which has been well documented. Recently, it is reported that SLPI is expressed in adipocytes and adipose tissue where it could play an important feedback role in the resolution of inflammation. Furthermore, circulating SLPI has been shown to correlate with progressive metabolic dysfunction. Moreover, adenoviral gene delivery of elafin and SLPI attenuates nuclear factor-kappaB-dependent inflammatory responses of human endothelial cells and macrophages to atherogenic stimuli. This review contributes to unraveling the protective role of SLPI in obesity-related atherosclerosis development, and the potential role in preventing arterial plaque rupture. PMID- 27698253 TI - A Legume TOR Protein Kinase Regulates Rhizobium Symbiosis and Is Essential for Infection and Nodule Development. AB - The target of rapamycin (TOR) protein kinase regulates metabolism, growth, and life span in yeast, animals, and plants in coordination with nutrient status and environmental conditions. The nutrient-dependent nature of TOR functionality makes this kinase a putative regulator of symbiotic associations involving nutrient acquisition. However, TOR's role in these processes remains to be understood. Here, we uncovered the role of TOR during the bean (Phaseolus vulgaris)-Rhizobium tropici (Rhizobium) symbiotic interaction. TOR was expressed in all tested bean tissues, with higher transcript levels in the root meristems and senesced nodules. We showed TOR promoter expression along the progressing infection thread and in the infected cells of mature nodules. Posttranscriptional gene silencing of TOR using RNA interference (RNAi) showed that this gene is involved in lateral root elongation and root cell organization and also alters the density, size, and number of root hairs. The suppression of TOR transcripts also affected infection thread progression and associated cortical cell divisions, resulting in a drastic reduction of nodule numbers. TOR-RNAi resulted in reduced reactive oxygen species accumulation and altered CyclinD1 and CyclinD3 expression, which are crucial factors for infection thread progression and nodule organogenesis. Enhanced expression of TOR-regulated ATG genes in TOR-RNAi roots suggested that TOR plays a role in the recognition of Rhizobium as a symbiont. Together, these data suggest that TOR plays a vital role in the establishment of root nodule symbiosis in the common bean.

AB - Stent insertion and chemical agents of ethylene diamine tetraacetic acid and sodium cholate for dissolving common bile duct stone diseases through extra biliary tract infusion have been believed a relatively effective therapeutics for the clinical symptom. Core-shell nanofibers produced by co-axial electrospinning to deliver chemical drugs, biomacromolecules, genes and even cells have been reported for various advanced drug delivery system and tissue engineering applications. In the present study, poly (lactide-co-E-caprolactone) (PLCL) core shell nanofiber-coated film of stent, loaded with ethylene diamine tetraacetic acid and sodium cholate in core layer, was fabricated by co-axial electrospinning for treating gallstone disease. Image of laser scanning confocal microscopy and transmission electron microscopy demonstrated core-shell structure of drug-loaded nanofiber. Fourier transform infrared spectra and the thermogravimetric analysis proved ethylene diamine tetraacetic acid and sodium cholate to be successfully loaded in nanofibers. Morphology of nanofibers after a period of degradation still keeps good shape. Drugs can continuously release for around five days, which was proved significant effectiveness for dissolving gallstone. Besides, unobvious cytotoxicity was exhibited from MTT results and cell kept good morphology in vitro research. The present coated stent showed a bright prospect for dissolving the biliary stone. PMID- 27698256 TI - Development and Testing of a Conceptual Model Regarding Men's Access to Health Care. AB - Epidemiologic data suggest men often experience excessive morbidity and early mortality, possibly compromising family and community health over the lifespan. Moreover, the negative financial/economic consequences affected by poor male health outcomes also has been of great concern in the United States and abroad. Early and consistent access to preventative health care may improve health outcomes; however, men are far less likely to access these services. The purpose of this study was to understand what factors preclude men from accessing health care. We surveyed 485 participants using a 58-item online survey built from a conceptual model previously developed by the researchers using hegemonic masculinity theory, the theory of normative contentment, and the health belief model. For men, three items significantly ( ps < .05) predicted whether they had seen a health care provider in the past year: "I/Men do not access healthcare because I do not think there is anything wrong with me," "My health is only about me," and "I/Men do not access healthcare because most men in my family do not access healthcare." Other correlations of practical significance also were noted. Results suggest gender norms and masculine ideals may play a primary role in how men access preventative health care. Future programming targeting males should consider barriers and plan programs that are gender-sensitive in addition to being gender-specific. Clinical implications are discussed.

Situations with high listening effort are thought to result in increased stress for the listener. The aim of this study was to explore possible measures to determine listening effort in situations with varying background noise and reverberation. For this purpose, subjective ratings of listening effort, speech recognition, and stress level, together with the electrodermal activity as a measure of the autonomic stress reaction, were investigated. It was expected that the electrodermal activity would show different stress levels in different acoustic situations and might serve as an alternative to subjective ratings. Ten young normal-hearing and 17 elderly hearing-impaired subjects listened to sentences from the Oldenburg sentence test either with stationary background noise or with reverberation. Four listening situations were generated, an easy and a hard one for each of the two disturbing factors, which were related to each other by the Speech Transmission Index. The easy situation resulted in 100% and the hard situation resulted in 30 to 80% speech recognition. The results of the subjective ratings showed significant differences between the easy and the hard listening situations in both subject groups. Two methods of analyzing the electrodermal activity values revealed similar, but nonsignificant trends. Significant correlations between subjective ratings and physiological electrodermal activity data were observed for normal-hearing subjects in the noise situation. PMID- 27698258 TI - Time-Varying Distortions of Binaural Information by Bilateral Hearing Aids: Effects of Nonlinear Frequency Compression. AB - In patients with bilateral hearing loss, the use of two hearing aids (HAs) offers the potential to restore the benefits of binaural hearing, including sound source localization and segregation. However, existing evidence suggests that bilateral HA users' access to binaural information, namely interaural time and level differences (ITDs and ILDs), can be compromised by device processing. Our objective was to characterize the nature and magnitude of binaural distortions caused by modern digital behind-the-ear HAs using a variety of stimuli and HA program settings. Of particular interest was a common frequency-lowering algorithm known as nonlinear frequency compression, which has not previously been assessed for its effects on binaural information. A binaural beamforming algorithm was also assessed. Wide dynamic range compression was enabled in all programs. HAs were placed on a binaural manikin, and stimuli were presented from an arc of loudspeakers inside an anechoic chamber. Stimuli were broadband noise bursts, 10-Hz sinusoidally amplitude-modulated noise bursts, or consonant-vowel consonant speech tokens. Binaural information was analyzed in terms of ITDs, ILDs, and interaural coherence, both for whole stimuli and in a time-varying sense (i.e., within a running temporal window) across four different frequency bands (1, 2, 4, and 6 kHz). Key findings were: (a) Nonlinear frequency compression caused distortions of high-frequency envelope ITDs and significantly reduced interaural coherence. (b) For modulated stimuli, all programs caused time varying distortion of ILDs. (c) HAs altered the relationship between ITDs and ILDs, introducing large ITD-ILD conflicts in some cases. Potential perceptual consequences of measured distortions are discussed. PMID- 27698260 TI - Rapid Release From Listening Effort Resulting From Semantic Context, and Effects of Spectral Degradation and Cochlear Implants. AB - People with hearing impairment are thought to rely heavily on context to compensate for reduced audibility. Here, we explore the resulting cost of this compensatory behavior, in terms of effort and the efficiency of ongoing predictive language processing. The listening task featured predictable or unpredictable sentences, and participants included people with cochlear implants as well as people with normal hearing who heard full-spectrum/unprocessed or vocoded speech. The crucial metric was the growth of the pupillary response and the reduction of this response for predictable versus unpredictable sentences, which would suggest reduced cognitive load resulting from predictive processing. Semantic context led to rapid reduction of listening effort for people with normal hearing; the reductions were observed well before the offset of the stimuli. Effort reduction was slightly delayed for people with cochlear implants and considerably more delayed for normal-hearing listeners exposed to spectrally degraded noise-vocoded signals; this pattern of results was maintained even when intelligibility was perfect. Results suggest that speed of sentence processing can still be disrupted, and exertion of effort can be elevated, even when intelligibility remains high. We discuss implications for experimental and clinical assessment of speech recognition, in which good performance can arise because of cognitive processes that occur after a stimulus, during a period of silence. Because silent gaps are not common in continuous flowing speech, the cognitive/linguistic restorative processes observed after sentences in such studies might not be available to listeners in everyday conversations, meaning that speech recognition in conventional tests might overestimate sentence processing capability. PMID- 27698259 TI - The Prediction of Speech Recognition in Noise With a Semi-Implantable Bone Conduction Hearing System by External Bone Conduction Stimulation With Headband: A Prospective Study. AB - Semi-implantable transcutaneous bone conduction devices are treatment options for conductive and mixed hearing loss (CHL/MHL). For counseling of patients, realistic simulation of the functional result is desirable. This study compared speech recognition in noise with a semi-implantable transcutaneous bone conduction device to external stimulation with a bone conduction device fixed by a headband. Eight German-language adult patients were enrolled after a semi implantable transcutaneous bone conduction device (Bonebridge, Med-El) was implanted and fitted. Patients received a bone conduction device for external stimulation (Baha BP110, Cochlear) fixed by a headband for comparison. The main outcome measure was speech recognition in noise (Oldenburg Sentence Test). Pure tone audiometry was performed and subjective benefit was assessed using the Glasgow Benefit Inventory and Abbreviated Profile of Hearing Aid Benefit questionnaires. Unaided, patients showed a mean signal-to-noise ratio threshold of 4.6 +/- 4.2 dB S/N for speech recognition. The aided results were -3.3 +/- 7.2 dB S/N by external bone conduction stimulation and -1.2 +/- 4.0 dB S/N by the semi-implantable bone conduction device. The difference between the two devices was not statistically significant, while the difference was significant between unaided and aided situation for both devices. Both questionnaires for subjective benefit favored the semi-implantable device over external stimulation. We conclude that it is possible to simulate the result of speech recognition in noise with a semi-implantable transcutaneous bone conduction device by external stimulation. This should be part of preoperative counseling of patients with CHL/MHL before implantation of a bone conduction device. PMID- 27698261 TI - A Binaural Grouping Model for Predicting Speech Intelligibility in Multitalker Environments. AB - Spatially separating speech maskers from target speech often leads to a large intelligibility improvement. Modeling this phenomenon has long been of interest to binaural-hearing researchers for uncovering brain mechanisms and for improving signal-processing algorithms in hearing-assistive devices. Much of the previous binaural modeling work focused on the unmasking enabled by binaural cues at the periphery, and little quantitative modeling has been directed toward the grouping or source-separation benefits of binaural processing. In this article, we propose a binaural model that focuses on grouping, specifically on the selection of time frequency units that are dominated by signals from the direction of the target. The proposed model uses Equalization-Cancellation (EC) processing with a binary decision rule to estimate a time-frequency binary mask. EC processing is carried out to cancel the target signal and the energy change between the EC input and output is used as a feature that reflects target dominance in each time-frequency unit. The processing in the proposed model requires little computational resources and is straightforward to implement. In combination with the Coherence based Speech Intelligibility Index, the model is applied to predict the speech intelligibility data measured by Marrone et al. The predicted speech reception threshold matches the pattern of the measured data well, even though the predicted intelligibility improvements relative to the colocated condition are larger than some of the measured data, which may reflect the lack of internal noise in this initial version of the model. PMID- 27698263 TI - Changes in Health-Related Quality of Life During Rehabilitation in Patients With Operable Lung Cancer: A Feasibility Study (PROLUCA). AB - INTRODUCTION: Surgical resection in patients with non-small cell lung cancer (NSCLC) may be associated with significant morbidity, functional limitations, and decreased quality of life. OBJECTIVES: The objective is to present health-related quality of life (HRQoL) changes over time before and 1 year after surgery in patients with NSCLC participating in a rehabilitation program. METHODS: Forty patients with NSCLC in disease stage I to IIIa, referred for surgical resection at the Department of Cardiothoracic Surgery RT, Rigshospitalet, were included in the study. The rehabilitation program comprised supervised group exercise program, 2 hours weekly for 12 weeks, combined with individual counseling. The study endpoints were self-reported HRQoL (Functional Assessment of Cancer Therapy Lung, European Organization for Research and Treatment in Cancer-Quality of Life Questionnaire-QLQ-C30, Short-Form-36) and self-reported distress, anxiety, depression, and social support (National Comprehensive Cancer Network Distress Thermometer, Hospital Anxiety and Depression Scale, Multidimensional Scale of Perceived Social Support), measured presurgery, postintervention, 6 months, and 1 year after surgery. RESULTS: Forty patients were included, 73% of whom completed rehabilitation. Results on emotional well-being ( P < .0001), global quality of life ( P = .0032), and mental health component score ( P = .0004) showed an overall statistically significant improvement during the study. CONCLUSION: This feasibility study demonstrated that global quality of life, mental health, and emotional well-being improved significantly during the study, from time of diagnosis until 1 year after resection, in patients with NSCLC participating in rehabilitation. PMID- 27698262 TI - Boehmenan, a Lignan From the Chinese Medicinal Plant Clematis armandii, Inhibits A431 Cell Growth via Blocking p70S6/S6 Kinase Pathway. AB - Previously, we have shown that boehmenan, a natural product isolated from the dried stem of Caulis clematidis armandii, exhibits various biological activities. The current study investigated the effects of boehmenan on the growth of human epidermoid carcinoma A431 cells. Cell viability and 50% inhibiting concentration (IC50) were assessed by CellTiter-Glo luminescent cell viability assay. Cell cycle arrest was measured by flow cytometry. Intracellular reactive oxygen species production and mitochondrial membrane potential (DeltaPsim) collapse were analyzed by a fluorescence spectrophotometer. The activation of epidermal growth factor receptor signaling pathway was evaluated by Western blot. The results showed that boehmenan significantly inhibited the growth of A431 cells (IC50 = 1.6 uM) in a concentration- and time-dependent manner. This compound also blocked cell cycle progression at G2/M phase and modulated mitochondrial apoptosis related proteins, as evidenced by upregulating p21, cleaved caspase-3, and cleaved poly (ADP-ribose) polymerase protein levels and by downregulating Bcl-2, pro-caspase-9 levels. In addition, boehmenan also markedly induced intracellular reactive oxygen species production and DeltaPsim depolarization in a concentration-dependent manner. Furthermore, boehmenan-attenuated epidermal growth factor mediated the phosphorylation of signal transducer and activator of transcription 3 (STAT3), p70 ribosomal protein S6 kinase (p70S6)/S6 in a concentration-dependent manner. Taken together, our results suggest that boehmenan-mediated antiproliferative property in A431 cells was mediated partially by modulation of mitochondrial function and inhibition of STAT3 and p70S6 signal pathways. PMID- 27698264 TI - Antitumor Activity of the Chinese Medicine JC-001 Is Mediated by Immunomodulation in a Murine Model of Hepatocellular Carcinoma. AB - JC-001 is a Chinese medicine that has been used to treat liver disease; however, its significance in cancer treatment has not been characterized. In this study, we used an immunocompetent tumor model to characterize the antitumor activity of JC-001. A total of 48 Hepa 1-6 tumor-bearing C57BL/6 mice were randomly grouped into 4 groups and treated with H2O or JC-001 via oral administration. After hepatoma cell lines, including HepG2, Hep3B, SK-Hep-1, and Hepa 1-6, underwent 96 hours of JC-001 treatment, a low cytotoxic effect was observed. In contrast, no direct cytotoxic effect of JC-001 on a normal human liver cell line, THLE-3, was observed under the same incubation conditions. Using a murine tumor model, we found that tumor growth could be inhibited by JC-001 in C57BL/6 mice but not in immunodeficient mice. Histopathological analysis of tumors from C57BL/6 mice revealed immune cell infiltration in tumors from the JC-001-treated group, as observed by hematoxylin and eosin staining; in addition, Ki67, hypoxia-inducible factor-1-alpha, and high mobility group box 1 expression levels were suppressed in the tumors. Both the coculture assay and murine spleen mRNA quantitative PCR analyses demonstrated that JC-001 could suppress Th17 immunity. Our data suggest that JC-001 is a Chinese medicine with low cytotoxicity that can significantly suppress tumor growth by immune regulation. This herbal remedy has great potential for future clinical application in hepatoma therapy. PMID- 27698267 TI - The future of dementia risk reduction research: barriers and solutions. AB - BACKGROUND: We examine why dementia prevention and risk reduction are relatively underfunded and suggest potential remediation strategies. The paper is aimed at researchers, funders and policy-makers, both within dementia and also the wider health prevention field. METHODS: A discussion-led workshop, attended by 58 academics, clinicians, funders and policy-makers. RESULTS: The key barriers identified were the gaps in understanding the basic science of dementia; the complex interplay between individual risk factors; variations in study methodology; disincentives to collaboration; a lack of research capacity and leadership and the broader stigma of the condition. Recommendations were made to encourage strategic leadership, provide greater support for grant applications, promote collaboration and support randomized control trials for the research field. CONCLUSION: Having identified the barriers, the key challenge is how to implement the potential solutions. This will require engagement with decision makers within funding, policy and research to ensure that action takes place. PMID- 27698265 TI - Emodin Exerts an Antiapoptotic Effect on Human Chronic Myelocytic Leukemia K562 Cell Lines by Targeting the PTEN/PI3K-AKT Signaling Pathway and Deleting BCR-ABL. AB - The BCR-ABL kinase inhibitor, imatinib mesylate, is the front-line treatment for chronic myeloid leukemia, but the emergence of imatinib resistance has led to the search for alternative drug treatments. There is a pressing need, therefore, to develop and test novel drugs. Natural products including plants, microorganisms, and halobios provide rich resources for discovery of anticancer drugs. In this article, we demonstrate that emodin inhibited the growth of K562 cells harboring BCR-ABL in vitro and in vivo, and induced abundant apoptosis, which was correlated with the inhibition of PETN/PI3K/Akt level and deletion of BCR-ABL. These findings suggest that emodin is a promising agent to kill K562 cells harboring BCR-ABL. PMID- 27698266 TI - Houttuynia cordata Thunb Promotes Activation of HIF-1A-FOXO3 and MEF2A Pathways to Induce Apoptosis in Human HepG2 Hepatocellular Carcinoma Cells. AB - Houttuynia cordata Thunb ( H cordata), a medicinal plant, has anticancer activity, as it inhibits cell growth and induces cell apoptosis in cancer. However, the potential anti-cancer activity and mechanism of H cordata for human liver cancer cells is not well understood. Recently, we identified hypoxia inducible factor (HIF)-1A, Forkhead box (FOX)O3, and MEF2A as proapoptotic factors induced by H cordata, suggesting that HIF-1A, FOXO3, and MEF2A contribute to the apoptosis of HepG2 hepatocellular carcinoma cells. FOXO3 transcription factors regulate target genes involved in apoptosis. H cordata significantly increased the mRNA and protein expression of HIF-1A and FOXO3 and stimulated MEF2A expression in addition to increased apoptosis in HepG2 cells within 24 hours. Therefore, we determined the potential role of FOXO3 on apoptosis and on H cordata-induced MEF2A in HepG2 cells. HIF-1A silencing by siRNA attenuated MEF2A and H cordata-mediated FOXO3 upregulation in HepG2 cells. Furthermore, H cordata mediated MEF2A expression enhanced caspase-3 and caspase-7, which were abolished on silencing FOXO3 with siRNA. In addition, H cordata inhibited growth of human hepatocellular carcinoma xenografts in nude mice. Taken together, our results demonstrate that H cordata enhances HIF-1A/FOXO3 signaling, leading to MEF2A upregulation in HepG2 cells, and in parallel, it disturbs the expression of Bcl-2 family proteins (Bax, Bcl-2, and Bcl-xL), which results in apoptosis. Taken together, these findings demonstrate that H cordata promotes the activation of HIF-1A-FOXO3 and MEF2A pathways to induce apoptosis in human HepG2 hepatocellular carcinoma cells and is, therefore, a promising candidate for antitumor drug development. PMID- 27698268 TI - Characteristics of good supervision: a multi-perspective qualitative exploration of the Masters in Public Health dissertation. AB - Background: A dissertation is often a core component of the Masters in Public Health (MPH) qualification. This study aims to explore its purpose, from the perspective of both students and supervisors, and identify practices viewed as constituting good supervision. Methods: A multi-perspective qualitative study drawing on in-depth one-to-one interviews with MPH supervisors (n = 8) and students (n = 10), with data thematically analysed. Results: The MPH dissertation was viewed as providing generic as well as discipline-specific knowledge and skills. It provided an opportunity for in-depth study on a chosen topic but different perspectives were evident as to whether the project should be grounded in public health practice rather than academia. Good supervision practice was thought to require topic knowledge, generic supervision skills (including clear communication of expectations and timely feedback) and adaptation of supervision to meet student needs. Conclusions: Two ideal types of the MPH dissertation process were identified. Supervisor-led projects focus on achieving a clearly defined output based on a supervisor-identified research question and aspire to harmonize research and teaching practice, but often have a narrower focus. Student-led projects may facilitate greater learning opportunities and better develop skills for public health practice but could be at greater risk of course failure. PMID- 27698269 TI - Community pharmacists' evaluation of potentially inappropriate prescribing in older community-dwelling patients with polypharmacy: observational research based on the GheOP3S tool. AB - Background: In this study, we aimed to (i) determine the prevalence of potentially inappropriate prescribing (PIP) in community-dwelling older polypharmacy patients using the Ghent Older People's Prescriptions community Pharmacy Screening (GheOP3S) tool, (ii) identify the items that account for the highest proportion of PIP and (iii) identify the patient variables that may influence the occurrence of PIP. Additionally, pharmacist-physician contacts emerging from PIP screening with the GheOP3S tool and feasibility of the GheOP3S tool in daily practice were evaluated. Methods: A prospective observational study was carried out between December 2013 and July 2014 in 204 community pharmacies in Belgium. Patients were eligible if they were (i) >=70 years, (ii) community dwelling, (iii) using >=5 chronic drugs, (iv) a regular visitor of the pharmacy and (v) understanding Dutch or French. Community pharmacists used a structured interview to obtain demographic data and medication use and subsequently screened for PIP using the GheOP3S tool. A Poisson regression was used to investigate the association between different covariates and the number of PIP. Results: In 987 (97%) of 1016 included patients, 3721 PIP items were detected (median of 3 per patient; inter quartile range: 2-5). Most frequently involved with PIP are drugs for the central nervous system such as hypnosedatives, antipsychotics and antidepressants. Risk factors for a higher PIP prevalence appeared to be a higher number of drugs (30% extra PIPs per 5 extra drugs), female gender (20% extra PIPs), higher body mass index (BMI, 20% extra PIPs per 10-unit increase in BMI) and poorer functional status (30% extra PIPs with 6-point increase). The feasibility of the GheOP3S tool was acceptable although digitalization of the tool would improve implementation. Despite detecting at least one PIP in 987 patients, only 39 physicians were contacted by the community pharmacists to discuss the items. Conclusion: A high prevalence of PIP in community-dwelling older polypharmacy patients in Belgium was detected which urges for interventions to reduce PIP.

AB - Visceral leishmaniasis (VL) is a vector-borne disease widespread in the Mediterranean basin, including Cyprus. During the last decades no cases were notified from northern Cyprus, but herein three cases of VL (female: 2, male: 1, median age: 24.6 months) diagnosed during their hospital admission between January 2011 and December 2012 are reported. Diagnosis was based on clinical findings; 1 >= 1/64 titer positivity of immunofluorescence antibodies, Leishmania amastigotes in Giemsa-stained slides of bone marrow, as well as molecular identification confirmed that in all three the infecting pathogen was Leishmania infantum Fever, splenomegaly, and hepatomegaly were the typical clinical findings. First-line treatment with liposomal amphotericin B (AmBisome(r); intravenous, 3 mg/kg) on days 1-5, followed by the same on days 10 and 21 yielded a successful outcome with no relapse in all cases. These confirmed VL cases found within 2 years demonstrate the presence of VL on the island. PMID- 27698272 TI - Observed Handwashing with Soap Practices Among Cholera Patients and Accompanying Household Members in a Hospital Setting (CHoBI7 Trial). AB - Household members of cholera patients are at a 100 times higher risk of cholera than the general population. Despite this risk, there are only a handful of studies that have investigated the handwashing practices among hospitalized diarrhea patients and their accompanying household members. To investigate handwashing practices in a hospital setting among this high-risk population, 444 hours of structured observation was conducted in a hospital in Dhaka, Bangladesh, among 148 cholera patients and their household members. Handwashing with soap practices were observed at the following key events: after toileting, after cleaning the anus of a child, after removing child feces, during food preparation, before eating, and before feeding. Spot-checks were also conducted to observe the presence of soap at bathroom areas. Overall, 4% (4/103) of key events involved handwashing with soap among cholera patients and household members during the structured observation period. This was 3% (1/37) among cholera patients and 5% (3/66) for household members. For toileting events, observed handwashing with soap was 7% (3/46) overall, 7% (1/14) for cholera patients, and 6% (2/32) for household members. For food-related events, overall observed handwashing with soap was 2% (2/93 overall), and 0% (0/34) and 3% (2/59) for cholera patients and household members, respectively. Soap was observed at only 7% (4/55) of handwashing stations used by patients and household members during spot-checks. Observed handwashing with soap at key times among patients and accompanying household members was very low. These findings highlight the urgent need for interventions to target this high-risk population. PMID- 27698273 TI - Chlorination of Household Drinking Water Among Cholera Patients' Households to Prevent Transmission of Toxigenic Vibrio cholerae in Dhaka, Bangladesh: CHoBI7 Trial. AB - Household members of cholera patients are at a 100 times higher risk of cholera infections than the general population because of shared contaminated drinking water sources and secondary transmission through poor household hygiene practices. In this study, we investigated the bactericidal concentration of free chlorine required to inactivate Vibrio cholerae in household drinking water in Dhaka, Bangladesh. In laboratory experiments, we found that the concentrations of free chlorine required to inactivate 105 colony-forming units (CFU)/mL of V. cholerae serogroups O1 and O139 were 0.1 mg/L and 0.2 mg/L, respectively. The concentration of free chlorine generated by a single chlorine tablet (sodium dichloroisocyanurate [33 mg]) after a 30-minute reaction time in a 10-L sealed vessel containing Dhaka city municipal supply water was 1.8 mg/L; and the concentration declined to 0.26 mg/L after 24 hours. In field measurements, water collected from 165 households enrolled in a randomized controlled trial (RCT) of a chlorine and handwashing with soap intervention (Cholera-Hospital-Based Intervention-for-7-Days [CHoBI7]), we observed significantly higher free chlorine concentrations in the 82 intervention arm households (mean = 1.12 mg/L, standard deviation [SD] = 0.52, range = 0.07-2.6 mg/L) compared with the 83 control households (0.017 mg/L, SD = 0.01, range = 0-0.06 mg/L) (P < 0.001) during spot check visits. These findings suggest that point-of-use chlorine tablets present an effective approach to inactivate V. cholerae from drinking water in households of cholera patients in Dhaka city. This result is consistent with the findings from the RCT of CHoBI7 which found that this intervention led to a significant reduction in symptomatic cholera infections among household members of cholera patients and no stored drinking water samples with detectable V. cholerae. PMID- 27698274 TI - Geophagy in Northern Uganda: Perspectives from Consumers and Clinicians. AB - The etiology and health consequences of geophagy are still poorly understood. The consumed soil, individual motives, consumption habits, and the clinical perspective of geophagy in northern Uganda were examined. A total of 50 semistructured interviews (17 pregnant, eight nonpregnant women, 10 men, and 15 health-care professionals) were conducted. Our results suggest that geophagy is not limited to pregnancy and can also be found among nonpregnant women and men. During gestation, excessive amounts of various soil types are consumed and can replace food at times. Nonpregnant women and men consume less soil and stick to one type. When pregnant, craving and alleviating gastrointestinal upset are the main motives. In men, the main reasons for geophagy were craving, hypersalivation, and natural stimulants. If soil is craved, it can show similarities to a dependency syndrome. When picked up in childhood, geophagy is more likely to be continued throughout life. The consumption habits differ and thereby vary in their possible implications on health. Our findings suggest that men should be included in further studies. Especially nurses from the antenatal care are exposed to geophagists; however, no national guidelines exist for geophagy. Further research is necessary to create guidelines to be included in medical training and practice. PMID- 27698275 TI - Spontaneous Splenic Rupture Caused by Scrub Typhus. AB - Spontaneous rupture of the spleen is rarely described as a complication of scrub typhus infection. We report a previously healthy 74-year-old Thai female farmer who presented in Nakhon Ratchasima, Thailand, with a history of fever and malaise for 5 days, followed by abdominal pain for 1 day. An exploratory laparotomy was performed due to peritonitis. Operative findings revealed a ruptured spleen and hemoperitoneum. A splenectomy was performed afterward. Scrub typhus was confirmed by a 4-fold increase of IgM titer using an indirect immunofluorescence antibody assay and a positive result from the polymerase chain reaction targeting the 47- and 56-kDa genes in Orientia tsutsugamushi She responded well to intravenous chloramphenicol and defervesced within 24 hours without any complication. PMID- 27698276 TI - Human Toxocariasis: Prevalence and Factors Associated with Biosafety in Research Laboratories. AB - Human toxocariasis is a neglected parasitic disease worldwide. Researchers studying this disease use infectious strains of Toxocara for experiments. Health workers are at risk in the course of their daily routine and must adhere to biosafety standards while carrying out the activities. Researchers on biosafety concerning working with these parasites are insufficient. The aim of this study was to determine the rate of seroprevalence of Toxocara species among health-care research laboratory workers (professors, technicians, and students), and to investigate the risk factors of Toxocara infection associated with laboratory practices. This cross-sectional study involved 74 researchers at two federal universities in southern Brazil from February 2014 to February 2015; 29 researchers manipulated infective strains of Toxocara canis (test group) and 45 did not (control group). Serum samples were examined using enzyme-linked immunosorbent assay. Epidemiological data were obtained via a questionnaire containing information about laboratory routine, eating behavior, and contact with dogs. The seroprevalence of anti-T. canis IgG was 14.9% (11/74; 13.8% [4/29] in the test group and 15.6% [7/45] in the control group). Most individuals in the test group correctly understood the primary mode of infection; however, 13.8% did not use gloves while manipulating T. canis eggs. Knowledge of biosafety must be well understood by health-care professionals doing laboratory work with biological agents. To our knowledge, this is the first study to investigate the rate of seroprevalence of IgG against Toxocara spp. among professionals and students who handle infective forms of the nematode T. canis.

AB - Since November 2011, Institut de radioprotection et de surete nucleaire (IRSN) experts have participated in the International Commission on Radiological Protection's (ICRP) dialogue initiative for the rehabilitation of living conditions after the Fukushima accident. In 2013, IRSN and Centre d'etude sur l'Evaluation de la Protection dans le domaine Nucleaire (CEPN) launched a study to identify the main lessons that can be learned from these dialogues, and benefit French IRSN experts in the event of a postaccident situation. The main lesson is that in order to protect the inhabitants of contaminated areas efficiently, experts must work in cooperation with local actors to develop a co expertise process. The availability of measurement devices for inhabitants is crucial to allow them to assess their own radiological situation. Measuring radioactivity makes it visible, and allows individuals to discuss the results in their communities and develop local projects to improve their daily life. Eventually, inhabitants create a practical radiological protection culture to manage their situation. However, helping people to protect themselves does not mean that authorities and experts have no responsibilities, and this calls for strong ethical principles such as not making decisions for people about their future. To be helpful, scientists need to understand that, as necessary as radiation protection is, it is not the only problem that inhabitants are facing and it cannot control people's lives. Radiation protection experts must commit themselves to be at the service of individuals and the community, and the issues they want to address. PMID- 27698277 TI - Community-Based Surveillance to Monitor Mortality in a Malaria-Endemic and Ebola Epidemic Setting in Rural Guinea. AB - Multiple community-based approaches can aid in quantifying mortality in the absence of reliable health facility data. Community-based sentinel site surveillance that was used to document mortality and the systems utility for outbreak detection was evaluated. We retrospectively analyzed data from 46 sentinel sites in three sous-prefectures with a reinforced malaria control program and one sous-prefecture without (Koundou) in Guinea. Deaths were recorded by key informants and classified as due to malaria or another cause. Malaria deaths were those reported as due to malaria or fever in the 3 days before death with no other known cause. Suspect Ebola virus disease (sEVD) deaths were those due to select symptoms in the EVD case definition. Deaths were aggregated by sous prefecture and analyzed by a 6-month period. A total of 43,000 individuals were monitored by the surveillance system; 1,242 deaths were reported from July 2011 June 2014, of which 55.2% (N = 686) were reported as due to malaria. Malaria attributable proportional mortality decreased by 26.5% (95% confidence interval [CI] = 13.9-33.1, P < 0.001) in the program area and by 6.6% (95% CI = -17.3 30.5, P = 0.589) in Koundou. Sixty-eight deaths were classified as sEVD and increased by 6.1% (95% CI = 1.3-10.8, P = 0.021). Seventeen sEVD deaths were reported from November 2013 to March 2014 including the first two laboratory confirmed EVD deaths. Community surveillance can capture information on mortality in areas where data collection is weak, but determining causes of death remains challenging. It can also be useful for outbreak detection if timeliness of data collection and reporting facilitate real-time data analysis. PMID- 27698279 TI - Looking back on media reports on the nuclear accident. AB - The accident at Fukushima Daiichi nuclear power plant in the wake of the Great East Japan Earthquake received considerable media coverage. However, a leaning towards sensationalism and a proclivity for denouncing those in power resulted in articles that were, in several instances, scientifically inaccurate, causing anxiety among disaster victims and delaying recovery efforts. Individuals working for the local media in Fukushima had the task of reporting the disaster while being victims of the disaster at the same time. Therefore, many individuals studied and deepened their knowledge about radiation and its effects, and were pained to see inaccurate media coverage of the disaster. Should they have been more forthright in opposing such false media coverage? PMID- 27698280 TI - CT-angiography source images indicate less fatal outcome despite coma of patients in the Basilar Artery International Cooperation Study. AB - Background Coma is associated with poor outcome in patients with basilar artery occlusion. Aims We sought to assess whether the posterior circulation Acute Stroke Prognosis Early CT Score and the Pons-Midbrain Index applied to CT angiography source images predict the outcome of comatose patients in the Basilar Artery International Cooperation Study. Methods Basilar Artery International Cooperation Study was a prospective, observational registry of patients with acute basilar artery occlusion with 48 recruiting centers worldwide. We applied posterior circulation Acute Stroke Prognosis Early CT Score and Pons-Midbrain Index to CT angiography source images of Basilar Artery International Cooperation Study patients who presented with coma. We calculated adjusted risk ratios to assess the association of dichotomized posterior circulation Acute Stroke Prognosis Early CT Score (>=8 vs. <8) and Pons-Midbrain Index (<3 vs. >=3) with mortality and favourable outcome (modified Rankin Scale score 0-3) at one month. Results Of 619 patients in the Basilar Artery International Cooperation Study registry, CT angiography source images were available for review in 158 patients. Among these, 78 patients (49%) presented with coma. Compared to non-comatose patients, comatose patients were more likely to die (risk ratios 2.34; CI 95% 1.56-3.52) and less likely to have a favourable outcome (risk ratios 0.44; CI 95% 0.24-0.80). Among comatose patients, a Pons-Midbrain Index < 3 was related to reduced mortality (adjusted RR 0.66; 95% CI 0.46-0.96), but not to favourable outcome (adjusted RR 1.19; 95% CI 0.39-3.62). Posterior circulation Acute Stroke Prognosis Early CT Score dichotomized at >= 8 vs. <8 was not significantly associated with death (adjusted RR 0.70; 95% CI 0.46-1.05). Conclusion In comatose patients with basilar artery occlusion, the extent of brainstem ischemia appears to be related to mortality but not to favourable outcome. PMID- 27698283 TI - Corrigendum.

Influence of patient behavior and other risk factors in the North Dublin Population Stroke Study. AB - Background Few studies have directly compared stroke recurrence rates after stroke and transient ischemic attack, and the risk factors underlying early recurrence are poorly understood. We aimed to investigate risk factors for recurrent stroke after first stroke and transient ischemic attack in a population based study. Methods The North Dublin Population Stroke Study applied multiple overlapping hot and cold pursuit methods, to ascertain hospital- and community treated stroke and transient ischemic attack patients over a 12-month period. Inclusion criteria were: (1) Stroke-physician confirmed transient ischemic attack/ischemic stroke; (2) first-stroke/transient ischemic attack event within the ascertainment period. Patients were prospectively followed at 72 h, 7, 28 and 90 days. Results A total of 584 patients met eligibility criteria (172 transient ischemic attack, 412 stroke). More transient ischemic attack than stroke patients presented to medical attention with recurrent stroke (8.24% vs. 0.24%, p = 0.0002). Recurrent stroke was more common after transient ischemic attack than index stroke at each time-interval (at 72 h, 4.07% vs. 1.23%, p = 0.03; at 90 days, 13.45% vs. 5.72%, p = 0.002). Stroke recurrence at 90 days was also associated with delay seeking medical attention after the index event (OR 3.2, p = 0.001), delayed anti-platelet (OR 2.8, p = 0.001) and statin (OR 2.4, p = 0.009) treatment, carotid stenosis/occlusion (OR 2.4, p = 0.008). On multivariable analysis, transient ischemic attack as index event (adjusted OR 2.3, p = 0.02), delayed statin treatment (OR 2.5, p = 0.02), and carotid stenosis/occlusion (OR 2.4, p = 0.02) were independent predictors of 90-day recurrent stroke. Conclusion A combination of pathophysiological and behavioral factors was associated with early stroke recurrence risk. Improved public awareness to reduce delays to self-referral for transient ischemic attack symptoms is needed.

AB - The ordering degree of nanostructures is the key to determining the uniformity of surface-enhanced Raman scattering (SERS). However, fabrication of large-area ordered nanostructures remains a challenge, especially with the ultrahigh-density (>1010 cm-2). Here, we report a fabrication of large-area ultrahigh-density ordered Ag@Al2O3/Ag core-shell nanosphere (NS) arrays with tunable nanostructures. The ultrahigh-density (2.8 * 1010 cm-2) ordered NS arrays over a large-area capability (diameter >4.0 cm) enable the uniform SERS signals with the relative standard deviation of less than 5%. The as-fabricated highly reproducible SERS substrate can be applied to detect trace phenolic pollutants in water. This work does not only provide a new route for synthesizing the ultrahigh density ordered nanostructures, but also create a new class of SERS substrates with high sensitivity and excellent reproducibility.

AB - Like Thomas Hardy's famous novel Far from the Madding Crowd, Plasmodium falciparum parasites display their most relevant survival structures (proteins) involved in host cell invasion far away from the immune system's susceptible regions, displaying tremendous genetic variability, to attract the immune response and escape immune pressure. The 3D structure localisation of the conserved amino acid sequences of this deadly parasite's most relevant proteins involved in host cell invasion, as well as the location of the highly polymorphic, highly immunogenic regions, clearly demonstrates that such structures are far apart, sometimes 90 degrees to 180 degrees opposite, thereby rendering the immune response useless. It is also shown here that these conserved, functionally-relevant structures are immunologically silent, since no immune response has been induce. PMID- 27698286 TI - Experimental and theoretical rationalization of the growth mechanism of silicon quantum dots in non-stoichiometric SiN x : role of chlorine in plasma enhanced chemical vapour deposition. AB - Silicon quantum dots (Si-QDs) embedded in an insulator matrix are important from a technological and application point of view. Thus, being able to synthesize them in situ during the matrix growth process is technologically advantageous. The use of SiH2Cl2 as the silicon precursor in the plasma enhanced chemical vapour deposition (PECVD) process allows us to obtain Si-QDs without post-thermal annealing. Foremost in this work, is a theoretical rationalization of the mechanism responsible for Si-QD generation in a film including an analysis of the energy released by the extraction of HCl and the insertion of silylene species into the terminal surface bonds. From the results obtained using density functional theory (DFT), we propose an explanation of the mechanism responsible for the formation of Si-QDs in non-stoichiometric SiN x starting from chlorinated precursors in a PECVD system. Micrograph images obtained through transmission electron microscopy confirmed the presence of Si-QDs, even in nitrogen-rich (N rich) samples. The film stoichiometry was controlled by varying the growth parameters, in particular the NH3/SiH2Cl2 ratio and hydrogen dilution. Experimental and theoretical results together show that using a PECVD system, along with chlorinated precursors it is possible to obtain Si-QDs at a low substrate temperature without annealing treatment. The optical property studies carried out in the present work highlight the prospects of these thin films for down shifting and as an antireflection coating in silicon solar cells.

AB - Guided growth of semiconductor nanowires in nanotube templates has been considered as a potential platform for reproducible integration of III-Vs on silicon or other mismatched substrates. Herein, we report on the challenges and prospects of molecular beam epitaxy of InAs nanowires in SiO2/Si nanotube templates. We show how and under which conditions the nanowire growth is initiated by In-assisted vapor-liquid-solid growth enabled by the local conditions inside the nanotube template. The conditions for high yield of vertical nanowires are investigated in terms of the nanotube depth, diameter and V/III flux ratios. We present a model that further substantiates our findings. This work opens new perspectives for monolithic integration of III-Vs on the silicon platform enabling new applications in the electronics, optoelectronics and energy harvesting arena.

AB - In the ethics of relations between physicians and paediatric patients the question of autonomy and its corollary, consent, is crucial.

Few events could cause such loss of life and damage to livelihoods. As witnessed with the recent West African Ebola outbreak, raising alerts and identifying the outbreak in the community took too long. As a consequence local health systems were quickly overwhelmed. In addition, response at the international level proved slow and poorly coordinated. Rapid diagnostics, effective therapeutics, protective equipment, and a vaccine were all lacking. The crisis was however ultimately halted, thanks to a massive deployment of international resources in combination with the bravery and compassion of the medical staff, scientists, healthcare and aid workers on the ground. Despite this triumph, the lingering psychological sequalae of Ebola remain a significant public health challenge. The importance of mental health service delivery and policy implementation in addition to public health funding resources will prove integral in tackling this issue in the long run. With this in mind, adopting a political ecology approach towards health and disease will be crucial in order to depathologize the clinically significant mental distress related to Ebola.

AB - INTRODUCTION: Climate change is a global emergency that influences human health and occupational safety. Global warming characterized by an increase in temperature of the ambience and humidity affects human health directly impairing body thermoregulation with serious consequences: dehydration, fatigue, heat stroke and even death. Several studies have demonstrated negative effects of climate change on working populations in a wide variety of workplaces with particular regard to outdoor and uncooled indoor workplaces. Most vulnerable workers are outdoor workers in tropical and subtropical countries usually involved in heavy labor during hot seasons. Many of the consequences therefore, regarding working people are possible, even without health symptoms by reducing work productivity. AIM: The scope of this review is to investigate effects of climate change on workers both in relation to health and work productivity. METHODS: This study has been realized by analyzing recent international literature. CONCLUSIONS: In order to reduce negative effects of climate change on working populations it is essential to implement preventive measures with a multidisciplinary strategy limiting health risks and improving work productivity. PMID- 27698291 TI - Global and Mediterranean climate change: a short summary. AB - : Observed changes at the global scale. An increase of the annual mean global temperature and changes of other climate parameters have been observed in the last century. The global temperature and the atmospheric concentration of greenhouse gases are changing at a very fast pace compared to those found in palaeoclimate records. Changes in the Mediterranean. Variations of some climate change indicators can be much larger at the local than at the global scale, and the Mediterranean has been indicated among the regions most sensitive to climate change, also due to the increasing anthropogenic pressure. Model projections for the Mediterranean foresee further warming, droughts, and long-lasting modifications. IMPACTS: Regional climate changes impact health and ecosystems, creating new risks, determined not only by weather events, but also by changing exposures and vulnerabilities. These issues, and in particular those regarding occupational safety, have not been sufficiently addressed to date. PMID- 27698293 TI - Impact of climate change on occupational exposure to solar radiation. AB - Occupational exposure to solar radiation may induce both acute and long-term effects on skin and eyes. Personal exposure is very difficult to assess accurately, as it depends on environmental, organisational and individual factors. The ongoing climate change interacting with stratospheric ozone dynamics may affect occupational exposure to solar radiation. In addition, tropospheric levels of environmental pollutants interacting with solar radiation may be altered by climate dynamics, so introducing another variable affecting the overall exposure to solar radiation. Given the uncertainties regarding the direction of changes in exposure to solar radiation due to climate change, compliance of outdoor workers with protective measures and a proper health surveillance are crucial. At the same time, education and training, along with the promotion of healthier lifestyles, are of paramount importance. PMID- 27698294 TI - The association between extreme weather conditions and work-related injuries and diseases. A systematic review of epidemiological studies. AB - INTRODUCTION: The relationship between extreme temperature and population health has been well documented. Our objective was to assess the evidence supporting an association between extreme temperature and work related injuries. METHODS: We carried out a systematic search with no date limits using PubMed, the Cochrane central register of controlled trials, EMBASE, Web of Science and the internet sites of key organizations on environmental and occupational health and safety. Risk of bias was evaluated with Cochrane procedure. RESULTS: Among 270 studies selected at the first step, we analyzed 20 studies according to inclusion criteria (4 and 16 referring to extreme cold and heat temperature, respectively). DISCUSSION: Despite the relevance for policy makers and for occupational safety authorities, the associations between extreme temperature and work related injuries is seldom analyzed. The estimation of risk, the identification of specific jobs involved and the characterization of the complex mechanisms involved could help to define prevention measures. PMID- 27698295 TI - Climate change and agricultural workers' health in Ecuador: occupational exposure to UV radiation and hot environments. AB - Climate change is a global concern but little is known about its potential health effects in workers from non-industrialized countries. Ecuadorian workers from the coast (hot environments) and Andean region (elevated UV radiation) might be at particular risk of such effects. In the Andean region, measurements of UV index show maximum levels exceeding 11, a level considered being extreme according to the WHO. Also, an increased incidence of skin cancer was reported the last decennium, this being the second most common cancer type in men and women. In the coast, a high reported prevalence of kidney disease in agricultural workers is suggested to be related to exposure to hot temperatures. The scarce data available on occupational health in Ecuadorian agricultural workers raise the need for further investigation. Data worldwide shows an increasing prevalence of UV radiation- and heat stress-related illnesses in agricultural workers and urges the adoption of preventive measures. PMID- 27698296 TI - Climate change: the potential impact on occupational exposure to pesticides. AB - OBJECTIVE: This study investigates the possible influence of global climate change (GCC) on exposure to plant protection products (PPP) in the workplace. METHODS: The paper has evaluated the main potential relationships between GCC and occupational exposure to pesticides, by highlighting how global warming might affect their future use and by reviewing its possible consequence on workers' exposure. RESULTS: Global warming, influencing the spatial and temporal distribution and proliferation of weeds, the impact of already present insect pests and pathogens and the introduction of new infesting species, could cause a changed use of pesticides in terms of higher amounts, doses and types of products applied, so influencing the human exposure to them during agricultural activities. GCC, in particular heat waves, may also potentially have impact on workers' susceptibility to pesticides absorption. CONCLUSIONS: Prevention policies of health in the workplace must be ready to address new risks from occupational exposure to pesticide, presumably different from current risks, since an increased use may be expected. PMID- 27698297 TI - Climate change and safety at work with ionizing radiations. AB - The accident at Tokyo Electric Power Company's (TEPCO's) Fukushima Daiichi nuclear power plant (NPP) has been one of the dominant topic in nuclear safety and it has brought new attention on the matter of accidents in NPPs due to external events related to natural causes. Climate change has risen new risks and the growing probability of extreme external events has increased exposure and vulnerability of workers in the nuclear sector. However extreme natural events are a threat not only to NPPs but to all facilities dealing with radioactive material and in an emergency scenario they can affect the effectiveness and implementation of safety devices and procedures and also prevent communications, causing delays in the readiness of response. It is clear that adaptation strategies are necessary to cope with emerging changes in climate and a new nuclear safety culture is growing, that addresses accidents initiated not only by internal but also by external events.

AB - INTRODUCTION: Climate change, air pollution, temperature increase and other environmental variables are modifying air quality, contributing to the increase of prevalence of allergic respiratory diseases. Allergies are complex diseases characterized by multilevel interactions between individual susceptibility, response to immune modulation and environmental exposures to physical, chemical and biological agents. Occupational allergies introduce a further complexity to these relationships by adding occupational exposure to both the indoor and outdoor ones in the living environment. OBJECTIVE: The aim of this paper is to overview climate-related allergy affecting environmental and occupational health, as literature data are scanty in this regard, and to suggest a management model of this risk based on a multidisciplinary approach, taking the case of biological pollution, with details on exposure and prevention. CONCLUSIONS: The management of climate-related occupational allergy should take into account preventive health strategies, environmental, public and occupational interventions, as well as to develop, implement, evaluate, and improve guidelines and standards protecting workers health under changing climatic conditions; new tools and strategies based on local conditions will have to be developed. Experimental studies and acquisition of environmental and personal data have to be matched to derive useful information for the scope of occupational health and safety. PMID- 27698298 TI - Climate change, vector-borne diseases and working population. AB - INTRODUCTION: Risks associated with climate change are increasing worldwide and the global effects include altered weather and precipitation patterns, rising temperatures and others; human health can be affected directly and indirectly. This paper is an overview of literature regarding climate changes, their interaction with vector-borne diseases and impact on working population. MATERIALS AND METHODS: Articles regarding climate changes as drivers of vector borne diseases and evidences of occupational cases have been picked up by public databank. Technical documents were also included in the study. RESULTS: Evidences regarding the impact of climate changes on vector-borne diseases in Europe, provided by the analysis of the literature, are presented. DISCUSSION: Climate sensitive vector-borne diseases are likely to be emerging due to climate modifications, with impacts on public and occupational health. However, other environmental and anthropogenic drivers such as increasing travelling and trade, deforestation and reforestation, altered land use and urbanization can influence their spread. Further studies are necessary to better understand the phenomenon and implementation of adaptation strategies to protect human health should be accelerated and strengthened. PMID- 27698300 TI - Towards a greener labour market: occupational health and safety implications. AB - BACKGROUND: Climate change and environmental degradation are seriously jeopardizing the future environmental and economic sustainability at the global level prompting urgent calls for a shift towards more sustainable development and greener economies. The use of the so called green jobs is a key strategy to overcome economic and ecological crisis. AIM: The present study discusses the implications for employment and decent work of green jobs in order to identify information/training measures to enhance skills of employees protecting their working conditions. RESULTS: Despite all the emphasis laid today on the green economy, occupational health and safety (OHS) issues have still been talked only limited, as already noted in previous studies and literature reviews. CONCLUSION: It is needed to assess traditional and new OHS risks within green jobs in order to facilitate the transfer of OHS knowledge to green technologies as well as identifying OHS training needs. PMID- 27698301 TI - Quality of life in refugees and asylum seekers in Italy: a pilot study. AB - Interest in measuring the Health Related Quality of Life (HRQoL) of the immigrants increased in recent years in Italy as in other countries. Our purpose was to evaluate the HRQoL of refugees welcomed in Tuscany using the SF-36 questionnaire. We collected 114 questionnaires from 2011 to 2015. Our samples was constituted by 98 males and 16 females, coming from different regions of the world; the mean age was 27.4. Statistical analysis showed that gender, length of stay and educational qualification are not associated with a poorer HRQoL. Instead, elderly refugees showed lower scores; refugees from African region reported a better HRQoL than the others, and there are also differences between refugees welcomed in different cities of Tuscany. Our purpose is to continue this study enlarging the sample size and the geographical coverage, in order to have a more interesting description of the health perception of refugees welcomed in Italy. PMID- 27698302 TI - Parent training education program: a pilot study, involving families of children with Prader-Willi syndrome. AB - INTRODUCTION: Prader-Willi syndrome (PWS) is a rare genetic disorder characterized by severe hypotonia during the neonatal period and the first two years of life, the onset of hyperphagia with a risk of obesity during infancy and adulthood, learning difficulties and behavioral or severe psychiatric problems. This complex disease has severe consequences and difficult management issues also for patients' families. Parents of children with PWS need appropriate psychoeducational intervention in order to better manage their children with PWS. The purpose of this study was the implementation and evaluation of a PWS psychoeducational parent training program. METHODS: The Italian National Center for Rare Diseases implemented a pilot parent training program offered to parents of children with PWS. The intervention's effects was evaluated using questionnaires comprised of 11 items rated on a 7 point Likert scale. RESULTS: The intervention was offered to 43 parents. The behavior problems management, dietary restrictions, autonomy and relationships were indicated by parents as the priority topics which needed to be addressed. Evaluations, immediately post intervention and after 6 months, were reported by parents, fulfilling specific questionnaires. 90% of parents involved in the study, appreciated the methodology, 86% felt more informed about PWS, 47-62% felt more capable to better approach behaviour's problems, 20-25% felt better about the child's health situation and future expectations. Feeling more capable to help the child autonomy and relationships were reported in 62% and 63% of parents respectively, which decreased significantly (p < 0.05) according to the evaluation 6 months after the intervention. Younger age of parents (< 44 years of age) was significantly correlated with better understanding on how to help the child's autonomy (OR: 0.05; CI: 0.04-0.8) and to better collaborate with the child's teachers (OR: 0.02; CI: 0.001-0.9). CONCLUSION: Parent training is a promising intervention for parents of children with behavior's problems. Interventions with a behaviorally oriented program, addressed to parents of PWS affected children, is a useful tool in increasing their ability to manage the problems related to the disease. PMID- 27698303 TI - Telemedicine in palliative care: a review of systematic reviews. AB - AIMS: To evaluate the quality of systematic reviews on telemedicine applications in palliative care. METHODS: A structured literature review was conducted to identify systematic reviews dealing with telemedicine in palliative care; the AMSTAR (Assessment of Multiple Systematic Reviews) checklist was used to appraise the evidence related to the systematic reviews. RESULTS: 405 records were initially identified; of these 14 were eligible for full-text analysis. In summary, the research strategy allowed the identification of 6 reviews to be included which showed a medium quality (AMSTAR score in between 4 and 7). All the included systematic reviews considered telemedicine applications as a feasible means to be used in palliative care; however, the positive findings are counterbalanced by several critical issues mainly related to the evidence from the primary studies included in each single review. CONCLUSIONS: Results of this first attempt to appraise the evidence in the field of telemedicine applications in palliative care highlighted that there is still limited evidence related to this approach. Strengths and weaknesses that impact on the general quality of the reviews were identified and relevant points to be taken into account for future research were suggested. PMID- 27698304 TI - Job stress models for predicting burnout syndrome: a review. AB - In Europe, the Council Directive 89/391 for improvement of workers' safety and health has emphasized the importance of addressing all occupational risk factors, and hence also psychosocial and organizational risk factors. Nevertheless, the construct of "work-related stress" elaborated from EU-OSHA is not totally corresponding with the "psychosocial" risk, that is a broader category of risk, comprising various and different psychosocial risk factors. The term "burnout", without any binding definition, tries to integrate symptoms as well as cause of the burnout process. In Europe, the most important methods developed for the work related stress risk assessment are based on the Cox's transactional model of job stress. Nevertheless, there are more specific models for predicting burnout syndrome. This literature review provides an overview of job burnout, highlighting the most important models of job burnout, such as the Job Strain, the Effort/Reward Imbalance and the Job Demands-Resources models. The difference between these models and the Cox's model of job stress is explored. PMID- 27698305 TI - Prevalence of breastfeeding in Italy: a population based follow-up study. AB - INTRODUCTION: Breastfeeding is widely recommended. Updated data are needed to assess its prevalence and the effectiveness of interventions. Breastfeeding practices in Italy need to be promoted and monitored with updated and standard data The objective of this study is to provide estimates of the prevalence of breastfeeding and exclusively breastfeeding and to identify factors that may be modified to improve them. MATERIALS AND METHODS: Two population-based follow-up surveys were conducted to evaluate the quality of maternal care in 25 Local Health Units (LHUs) in Italy during 2008-2011. Women were interviewed soon after giving birth and after 3, 6 and 12 months. Breastfeeding prevalences were estimated. A logistic regression model was used to investigate factors associated with exclusive breastfeeding at 3 months. RESULTS: Breastfeeding and exclusively breastfeeding prevalence estimates were 91.6% and 57.2% at discharge, 71.6% and 48.6% at 3 months, 57.7% and 5.5% at 6 months. At 12 months, 32.5% were still breastfeeding. Women who are more likely to exclusively breastfeed at 3 months are multiparous, more educated, resident in the north/center, have attended antenatal classes and groups of breastfeeding support, have practiced the skin-to skin contact in hospital and have initiated breastfeeding early. CONCLUSION: In Italy many mothers do not comply with breastfeeding recommendations. The promotion and support of breastfeeding is still necessary in Italy and still needs to be monitored with representative data. Actions should aim at empowering women, reducing social inequalities and improving practices in hospitals and maternal care services which encourage breastfeeding. PMID- 27698306 TI - Absolute structure determination: pushing the limits. PMID- 27698307 TI - Why direct and post-refinement determinations of absolute structure may give different results. AB - Direct determination of the Flack parameter as part of the structure refinement procedure usually gives different, though similar, values to post-refinement methods. The source of this discrepancy has been probed by analysing a range of data sets taken from the recent literature. Most significantly, it was observed that the directly refined Flack (x) parameter and its standard uncertainty are usually not much influenced by changes in the refinement weighting schemes, but if they are then there are probably problems with the data or model. Post refinement analyses give Flack parameters strongly influenced by the choice of weights. Weights derived from those used in the main least squares lead to post refinement estimates of the Flack parameters and their standard uncertainties very similar to those obtained by direct refinement. Weights derived from the variances of the observed structure amplitudes are more appropriate and often yield post-refinement Flack parameters similar to those from direct refinement, but always with lower standard uncertainties. Substantial disagreement between direct and post-refinement determinations are strongly indicative of problems with the data, which may be difficult to identify. Examples drawn from 28 structure determinations are provided showing a range of different underlying problems. It seems likely that post-refinement methods taking into account the slope of the normal probability plot are currently the most robust estimators of absolute structure and should be reported along with the directly refined values.

AB - The synthesis, characterization, structural analysis and fluorescence properties of two rhodamine 6G derivatives are described, namely a propargylamine derivative, 3',6'-bis(ethylamino)-2',7'-dimethyl-2-(methylcyanide)spiro[isoindole 1,9'-xanthen]-3(2H)-one (I), and a gamma-aminobutyric acid (GABA) derivative, 3',6'-bis(ethylamino)-2',7'-dimethyl-3-oxospiro[isoindole-1,9'-xanthen]-2(3H) yl)butyricacid (II). Both structures are compared with four similar ones from the Cambridge Structural Database (CSD), and the interactions involved in the stabilization are analyzed using the atoms in molecules (AIM) theory. Finally, a single-crystal in-situ reaction study is presented, carried out by fluorescence methods, which enabled the 'opening' of the spirolactam ring in the solid phase. PMID- 27698309 TI - Br...Br and van der Waals interactions along a homologous series: crystal packing of 1,2-dibromo-4,5-dialkoxybenzenes. AB - The crystalline structures of four homologues of the 1,2-dibromo-4,5 dialkoxybenzene series [Br2C6H2(OCnH2n + 1)2 for n = 2, 12, 14 and 18] have been solved by means of single-crystal crystallography. Comparison along the series, including the previously reported n = 10 and n = 16 derivatives, shows a clear metric trend (b and c essentially fixed along the series and a growing linearly with n), in spite of some subtle differences in space groups and/or packing modes. A uniform packing pattern for the aliphatic chains has been found for the n = 12 to 18 homologues, which slightly differs from that of the n = 10 derivative. The crystalline structures of all the higher homologues (n = 10-18) seem to arise from van der Waals interchain interactions and, to a lesser extent, type II Br...Br interactions. The dominant role of interchain interactions provides direct structural support for the usual interpretation of melting point trends like that found along this series. Atoms in Molecules (AIM) analysis allows a comparison of the relative magnitude of the interchain and Br...Br interactions, an analysis validated by the measured melting enthalpies. PMID- 27698310 TI - Effect of Al and Ca co-doping, in the presence of Te, in superconducting YBCO whiskers growth. AB - High-Tc superconducting cuprates (HTSC) such as YBa2Cu3O7 - x (YBCO) are promising candidates for solid-state THz applications based on stacks of intrinsic Josephson junctions (IJJs) with atomic thickness. In view of future exploitation of IJJs, high-quality superconducting YBCO tape-like single crystals (whiskers) have been synthesized from Ca-Al-doped precursors in the presence of Te. The main aim of this paper is to determine the importance of the simultaneous use of Al, Te and Ca in promoting YBCO whiskers growth with good superconducting properties (Tc = 79-84 K). Further, single-crystal X-ray diffraction (SC-XRD) refinements of tetragonal YBCO whiskers (P4/mmm) are reported to fill the literature lack of YBCO structure investigations. All the as-grown whiskers have also been investigated by means of X-ray powder diffraction (XRPD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). Our results demonstrate that the interplay of Ca, Te and Al elements is clearly necessary in order to obtain superconducting YBCO whiskers. The data obtained from SC-XRD analyses confirm the highly crystalline nature of the whiskers grown. Ca and Al enter the structure by replacing the Y and the octahedral coordinated Cu1 site, respectively, as in other similar orthorhombic compounds, while Te does not enter the structure of whiskers but its presence in the precursor is essential to the growth of the crystals.

Utilization of 1,2-AEPi, 2,2 AEPy and 1,2-AEPr as disubstituents on TCNQ has resulted in interesting crystal structures. Inter- and intramolecular hydrogen-bond mediated and expanded supramolecular structures were observed in the lattices of the crystals. Strong fluorescence was observed in solids and solutions. (2) showed a strong second harmonic generation (SHG) whereas (1) and (3) were found to be SHG inactive. All compounds possess good thermal stabilities.

AB - The crystal structure of the pristine (I) and aged (II) crystals of CH3NH3PbI3 (hereafter MAPbI3) hybrid organic-inorganic lead iodide has been studied at 293 K with high-precision single-crystal X-ray diffraction using a synchrotron light source. We show that (I) and (II) are characterized by an identical tetragonal unit cell but different space groups: I422 for (I) and P42212 for (II). Both space groups are subgroups of I4/mcm, which is widely used for MAPbI3. The main difference between (I) and (II) comes from the difference in hydrogen bonds between the MA+ cation and the PbI3 framework which is the direct consequence of H2O insertion in the aged crystal (II).

AB - High-resolution transmission electron microscopy (HRTEM) studies of silicon after treatment in a planetary mill have been performed. It is shown that along with the initial phase of silicon, Si-I, the sample also contains some high-pressure phases: Si-III (Kasper phase) and Si-IV (lonsdaleite). We studied the orientation relationship between the particles of different phases, finding that there are, in general, two mechanisms of formation of Si-IV: (1) through the stacking faults formation; (2) through the transformation first to the Kasper phase (Si-III), and then from the Kasper phase to Si-IV. Estimations of temperature and pressure conditions in the planetary ball mill made previously are in accordance with the conditions of formation of the above-mentioned phases.

AB - In the present work, novel salts of the multimodal antidepressant drug vortioxetine (VT) were crystallized with pharmaceutically acceptable acids, aiming to improve the solubility of VT. The acids for VT were selected based on DeltapKa being greater than 2 or 3. Salts of hydrobromic acid (HBr), hydrochloric acid (HCl), p-hydroxybenzoic acid (PHBA), saccharin (SAC) and L-aspartic acid (ASP) were reported. All salts were characterized by single-crystal X-ray diffraction, FT-IR, powder X-ray diffraction (PXRD) and differential scanning calorimetry (DSC). The acidic proton is transferred to the secondary N atom on the piperazine ring of VT, forming the charge-assisted hydrogen bond N+-H...X- (X = Cl, Br, O). Solubility and intrinsic dissolution rate (IDR) experiments were carried out in distilled water (pH = 7.0) to compare the solubilities of the salts with that of VT. The VT-ASP-H2O (1:1:2) salt showed 414 times higher solubility and 1722 times faster IDR compared with VT. VT-ASP-H2O (1:1:2) is a high solubility salt that is stable in a slurry experiment at 298 K in 95% ethanol. The experimental data for the VT-ASP-H2O (1:1:2) salt identify it as a promising drug candidate. PMID- 27698315 TI - Accurate unrestrained DDM refinement of crystal structures from highly distorted and low-resolution powder diffraction data. AB - The structure of benzene:ethane co-crystal at 90 K is refined with anisotropic displacement parameters without geometric restraints from high-resolution synchrotron X-ray powder diffraction (XRPD) data using the derivative difference method (DDM) with properly chosen weighting schemes. The average C-C bond precision achieved is 0.005 A and the H-atom positions in ethane are refined independently. A new DDM weighting scheme is introduced that compensates for big distortions of experimental data. The results are compared with density functional theory (DFT) calculations reported by Maynard-Casely et al. [(2016). IUCrJ, 3, 192-199] where a rigid-body Rietveld refinement was also applied to the same dataset due to severe distortions of the powder pattern attributable to experimental peculiarities. For the crystal structure of 2-aminopyridinium fumarate-fumaric acid formerly refined applying 77 geometric restraints by Dong et al. [(2013). Acta Cryst. C69, 896-900], an unrestrained DDM refinement using the same XRPD pattern surprisingly gave two times narrower dispersion of interatomic distances.

AB - The crystallization behavior of trimethylsilyl-capped (3Z)-4-(methylthio)-3 penten-1-yne (1-TMS) and the triisopropylsilyl and tert-butyldimethylsilyl analogues (1-TIPS) and (1-TBDMS) was investigated. (1-TMS) crystallizes in the Sohncke space group P212121 with Z' = 1. (1-TIPS) exists as two polymorphs, both crystallizing in P?overline 1 with Z' = 2 independent molecules. Polymorph (I) is an order-disorder (OD) twin. Two interpretations in terms of M = 1 or M = 2 kinds of OD layers are possible, with different degrees of idealization. Polymorph (II) is fully ordered (non-twinned). Its structure can be derived from polymorph (I) by inverting the orientation of every second molecule. (1-TBDMS) (P?overline1, Z' = 2) is an OD twin, where the OD description is unambiguously in M = 1 kinds of layers.

AB - Vesuvianite containing 5.85 wt% TiO2 from an Alpine-cleft-type assemblage outcropped near Alchuri, Shigar Valley, Northern Areas, Pakistan, has been investigated by means of electron microprobe analyses, gas-chromatographic analysis of H2O, X-ray powder diffraction, single-crystal X-ray structure refinement, 27Al NMR, 57Fe Mossbauer spectroscopy, IR spectroscopy and optical measurements. Tetragonal unit-cell parameters are: a = 15.5326 (2), c = 11.8040 (2) A, space group P4/nnc. The structure was refined to final R1 = 0.031, wR2 = 0.057 for 11247 I > 2sigma(I). A general crystal-chemical formula of studied sample can be written as follows (Z = 2): [8-9](Ca17.1Na0.9) [8]Ca1.0[5](Fe2+0.44Fe3+0.34Mg0.22) [6](Al3.59Mg0.41) [6](Al4.03Ti2.20Fe3+1.37Fe2+0.40) (Si18O68) [(OH)5.84O2.83F1.33]. The octahedral site Y2 is Al-dominant and does not contain transition elements. Another octahedral site Y3 is also Al-dominant and contains Fe2+, Fe3+ and Ti. The site Y1 is split into Y1a and Y1b predominantly occupied by Fe2+ and Fe3+, respectively. The role of the Y1 site in the diversity of vesuvianite-group minerals is discussed.

AB - Two hydrogen-bonded, well defined compounds were synthesized from tris(2,6 diisopropyl)phenoxysilanethiol (TDST) and triethylamine (TDST-TEA) or pyridine (TDST-py). The crystalline compounds were characterized in the solid state by variable-temperature X-ray diffraction measurements and ATR FT-IR spectroscopy. The toluene solutions of TDST-TEA and TDST-py were studied by NMR spectroscopy. The total hydrogen-bond energies and FT-IR spectra were calculated with the use of BLYP-D/TZP and B3LYP/6-31G(d,p)/GD3BJ methods. Thermochemical parameters and potential energy scans were calculated at the B3LYP/6-31G(d,p)/GD3BJ level. All results point to the higher energy of bonding in TDST-TEA both in the solid state and in solution. At the same time the potential energy scan reveals a very broad double-well hydrogen bond in TDST-py, indicating good stabilization of the system for a wide range of D-H...A distances.

PMID- 27698320 TI - Topological characterization of electron density, electrostatic potential and intermolecular interactions of 2-nitroimidazole: an experimental and theoretical study. AB - An experimental charge density distribution of 2-nitroimidazole was determined from high-resolution X-ray diffraction and the Hansen-Coppens multipole model. The 2-nitroimidazole compound was crystallized and a high-angle X-ray diffraction intensity data set has been collected at low temperature (110 K). The structure was solved and further, an aspherical multipole model refinement was performed up to octapole level; the results were used to determine the structure, bond topological and electrostatic properties of the molecule. In the crystal, the molecule exhibits a planar structure and forms weak and strong intermolecular hydrogen-bonding interactions with the neighbouring molecules. The Hirshfeld surface of the molecule was plotted, which explores different types of intermolecular interactions and their strength. The topological analysis of electron density at the bond critical points (b.c.p.) of the molecule was performed, from that the electron density rhobcp(r) and the Laplacian of electron density ?2rhobcp(r) at the b.c.p.s of the molecule have been determined; these parameters show the charge concentration/depletion of the nitroimidazole bonds in the crystal. The electrostatic parameters like atomic charges and the dipole moment of the molecule were calculated. The electrostatic potential surface of the molecule has been plotted, and it displays a large electronegative region around the nitro group. All the experimental results were compared with the corresponding theoretical calculations performed using CRYSTAL09.

AB - Despite being one of the most common minerals in the earth's crust the crystal structure of intermediate e-plagioclase remains only partially understood, due in a large part to its complex diffraction patterns including satellite reflections. In this article we present a detailed analysis of the structure of e-plagioclase (An44) using single-crystal X-ray diffraction measured at ambient and low temperature (T = 100 K), in which the full modulated structure is successfully refined. As in earlier studies, the diffraction pattern exhibits strong main a reflections and weak e-satellite reflections. The average structure could be solved in terms of an albite-like basic cell with the triclinic centrosymmetric and non-centrosymmetric space groups P ?bar 1 and P1 (treated in its C ?bar 1 and C1 setting, respectively, to follow conventions in the literature), while the incommensurately modulated structure was modeled in (3 + 1)D superspace, employing both the centro- and non-centrosymmetric superspace groups X ?bar 1(alphabetagamma)0 and X1(alphabetagamma)0, where X refers to a special (3 + 1)D lattice centering with centering vectors (0 0 1/2 1/2), (1/2 1/2 0 1/2), and (1/2 1/2 1/2 0). Individual positional and occupational modulations for Ca/Na were refined with deeper insights being revealed in the non-centrosymmetric structure model. Through the structural details emerging from this model, the origin of the modulation can be traced to the communication between Ca/Na site positions through their bridging aluminosilicate (Si/Al)O4 tetrahedra. PMID- 27698323 TI - Functional Magnetic Resonance Imaging Correlates of First-Episode Psychoses during Attentional and Memory Task Performance. AB - BACKGROUND: The nature of the alteration of the response to cognitive tasks in first-episode psychosis (FEP) still awaits clarification. We used activation likelihood estimation, an increasingly used method in evaluating normal and pathological brain function, to identify activation changes in functional magnetic resonance imaging (fMRI) studies of FEP during attentional and memory tasks. METHODS: We included 11 peer-reviewed fMRI studies assessing FEP patients versus healthy controls (HCs) during performance of attentional and memory tasks. RESULTS: Our database comprised 290 patients with FEP, matched with 316 HCs. Between-group analyses showed that HCs, compared to FEP patients, exhibited hyperactivation of the right middle frontal gyrus (Brodmann area, BA, 9), right inferior parietal lobule (BA 40), and right insula (BA 13) during attentional task performances and hyperactivation of the left insula (BA 13) during memory task performances. CONCLUSIONS: Right frontal, parietal, and insular dysfunction during attentional task performance and left insular dysfunction during memory task performance are significant neural functional FEP correlates. PMID- 27698324 TI - Cytomorphologic and Immunophenotypic Profile of a Cohort of Small Cell Carcinoma of the Urinary Bladder. AB - BACKGROUND: The incidence of primary small cell carcinoma (SCC) of the urinary bladder is extremely rare. We sought to analyze the cytologic and immunophenotypic features of SCC of the urinary bladder in urine and reassert the importance of cytologic examination of urine specimens for diagnosis of this tumor. METHODS: We studied the clinical and cytomorphologic features in the presurgical urine specimens (4 voided urine and 2 bladder-washing specimens) of histopathologically and immunohistochemically proven cases of SCC of the urinary bladder. RESULTS: There were 6 cases, all males, with an age range of 61-81 years. On cytologic and histopathologic examination, typical SCC morphology was present in all cases. On immunohistochemistry, synaptophysin and CD56 were positive in all 6 cases, while chromogranin was positive in only 3. The Ki-67 labeling index ranged from 30 to 100%. CONCLUSIONS: SCC should be kept in the differential diagnosis, when high-grade urothelial carcinoma is suspected in a urine cytology specimen, as this distinction has important therapeutic and prognostic implications. Therefore, a careful observation and, if required, the use of an appropriate immunocytochemical panel on the presurgical urine specimens can lead to a correct diagnosis. PMID- 27698325 TI - Use of an Image Acquisition Stabilizer Improves Sidestream Dark Field Imaging of the Serosa during Open Gastrointestinal Surgery. AB - AIM: To investigate whether an image acquisition stabilizer (IAS) mounted on the sidestream dark field camera (SDF) during gastrointestinal surgery improves image stability and acquisition. METHODS: Serosal SDF imaging was compared with SDF imaging combined with an IAS (SDF + IAS) during gastrointestinal surgery. Stability was assessed as the image drift in pixels and the time to obtain stable images. The success rate was determined as the percentage of analyzable images after recording. The effect of negative pressure from the IAS was determined during single-spot measurements and by comparing microvascular parameters between groups. Data are presented as mean +/- SD. RESULTS: Sixty serosal measurements were performed per group; 87% were successful in the SDF group and 100% in the SDF + IAS group (p = 0.003). Image drift in the SDF group was 148 +/- 36 versus 55 +/- 15 pixels in the SDF + IAS group; p < 0.001. Time to stable image was 96 +/- 60 s in the SDF group versus 57 +/- 31 s in the SDF + IAS group; p = 0.03. No effect of negative pressure was seen. CONCLUSION: The use of an IAS mounted on an SDF camera during serosal microvascular assessment improves the success rate of image acquisition and stability and reduces the time to stable image with no effect on the microcirculation. PMID- 27698327 TI - Efficacy of Dapsone in the Treatment of Pemphigus Vulgaris: A Single-Center Case Study. AB - BACKGROUND: Pemphigus vulgaris (PV) is a chronic autoimmune blistering disease. Most patients require long-term therapy with systemic steroids, and a steroid sparing agent is usually also utilized. Dapsone is a chemotherapeutic agent with anti-inflammatory properties that is used as a steroid-sparing agent in PV. OBJECTIVE: The aim of the present study was to evaluate the efficacy of dapsone as an adjuvant therapy in patients with PV. METHODS: A retrospective analysis of patients' files was performed. All 26 patients included in the study group were treated with dapsone as an adjuvant to systemic steroids for at least 3 consecutive months and were followed up during their dapsone treatment period. RESULTS: After 3 months of treatment with dapsone, 13 patients were in the consolidation phase, 4 patients demonstrated partial remission on minimal therapy, 7 patients demonstrated complete remission on minimal therapy, and 2 patients were defined as treatment failures. The trend of clinical improvement continued after 6 months of treatment and at the study end point. CONCLUSION: This retrospective case series, one of the largest reported, indicates that dapsone is efficacious and safe for patients with PV in whom it is well tolerated soon after the initiation of treatment.

AB - BACKGROUND: This is an investigation of complete arterial coronary artery bypass grafting (CACABG) using bilateral internal mammary arteries (IMA) and the T-graft technique either on- or off-pump as a routine approach to treat coronary artery disease. METHODS: Between January 2000 and December 2012, 3,445 patients underwent on-pump (n = 2,216) or off-pump (n = 1,229) CACABG. A 30-day follow-up was performed prospectively, a long-term follow-up by a questionnaire, and coronary angiography in selected patients. RESULTS: End points at 30 days were death, myocardial infarction, stroke, repeat revascularization, renal replacement, reoperation, sternal wound infection and atrial fibrillation. FitzGibbon A patency rates were 89.8 vs. 91.4% (p = 0.464) with consecutive percutaneous coronary intervention in the grafted area of 1.8 vs. 1.1% (p = 0.693) on- vs. off-pump, and no reoperation in the grafted area in both groups. CONCLUSION: CACABG by use of skeletonized bilateral IMA with the T-graft technique performed either on- or off-pump is a safe and effective approach.

AB - BACKGROUND Chronic allograft dysfunction (CAD) is the major factor endangering the long-term allograft survival in kidney transplantation. The mechanisms of CAD remain unclear. MATERIAL AND METHODS A total of 64 renal transplant recipients were enrolled in our study and divided into a stable group and CAD group according to their allograft function. A group of 32 normal controls (healthy volunteers) were also included. An ELISA was used to detect serum interleukin-33 (IL-33), IL-2, IL-4, IL-10, IL-17, and interferon-gamma (IFN-gamma). Flow cytometry was performed to measure the percentage of CD3+CD4+ and CD3+CD8+ T cells in the peripheral blood from the three patient groups. The correlations among the study indexes were also analyzed using Pearson's method. RESULTS Levels of serum IL-33 was significantly higher in CAD patients than recipients with stable allograft function. Moreover, serum IL-2, IL-4, and IL-10 also increased statistically in patients with CAD. In addition, significant differences were observed in CD4+ T cells and the ratio of CD4+ and CD8+ T cells between CAD and stable patients. CONCLUSIONS Serum upregulated IL-33 could contribute to the pathogenesis of CAD in kidney transplant recipients. PMID- 27698338 TI - Alacrima as a Harbinger of Adrenal Insufficiency in a Child with Allgrove (AAA) Syndrome. AB - BACKGROUND Allgrove syndrome, or triple "A" syndrome (3A syndrome), is a rare autosomal recessive syndrome with variable phenotype, and an estimated prevalence of 1 per 1,000,000 individuals. Patients usually display the triad of achalasia, alacrima, and adrenocorticotropin (ACTH) insensitive adrenal insufficiency, though the presentation is inconsistent. CASE REPORT Here, the authors report a case of Allgrove syndrome in a pediatric patient with delayed diagnosis in order to raise awareness of this potentially fatal disease as a differential diagnosis of alacrima. CONCLUSIONS The prevalence of Allgrove syndrome may be much higher as a result of underdiagnosis and missed diagnosis due to the variable presentation and sudden unexplained childhood death from adrenal crisis. The authors review the characteristic symptoms of Allgrove syndrome in relation to the case study in order to avoid missed or delayed diagnosis, potentially decreasing morbidity, and mortality in those affected by this disease. PMID- 27698339 TI - Total Arterial Revascularization: Bypassing Antiquated Notions to Better Alternatives for Coronary Artery Disease. AB - Total arterial revascularization is the leading trend in coronary artery bypass grafting (CABG) for the treatment of coronary artery disease (CAD). Adding to its superiority to vein conduits, arteries allow for a high degree of versatility and long-term patency, while minimizing the need for reintervention. This is especially important for patients with multi-vessel coronary artery disease, as well as young patients. However, arterial revascularization has come a long way before being widely appreciated, with some yet unresolved debates, and advances that never cease to impress. In this review, we discuss the evolution of this surgical technique and its clinical success, as well as its most conspicuous limitations in light of accumulated published date from decades of experience. PMID- 27698340 TI - Golgi Phosphoprotein 3 Inhibits the Apoptosis of Human Glioma Cells in Part by Downregulating N-myc Downstream Regulated Gene 1. AB - BACKGROUND Golgi phosphoprotein 3 (GOLPH3) has been reported to be involved in the development of several human cancers. Our previous study showed that GOLPH3 expression in glioma tissues was related to the severity of the malignancy of the cancer. However, the mechanism by which GOLPH3 affects cell apoptosis is largely unknown. The present study was designed to explore the possible mechanism of GOLPH3 in cell apoptosis. MATERIAL AND METHODS To analyze the biological role of GOLPH3 in glioma cells, we used GOLPH3 small interference RNA in apoptosis of glioma cells. The apoptosis of glioma cells was detected by flow cytometry. The expression level of GOLPH3 and NDRG1 protein was determined by Western blot analyses and immunohistochemical staining, respectively, to evaluate their association with glioma. Tumor tissues were collected from patients with glioma. Normal cerebral tissues were acquired from cerebral trauma patients undergoing internal decompression surgery. RESULTS We confirm that the decrease of GOLPH3 that promotes the apoptosis of glioma cells may be regulated by the activation of NDRG1 and cleaved capcase 3. There was a inverse association between GOLPH3 and NDRG1 in glioma samples. CONCLUSIONS Our findings indicate that GOLPH3 and NDRG1 both play an important role in glioma etiology. Either GOLPH3 or NDRG1 might be a potential candidate for malignant glioma therapy. PMID- 27698341 TI - Self-amplified photo-induced gap quenching in a correlated electron material. AB - Capturing the dynamic electronic band structure of a correlated material presents a powerful capability for uncovering the complex couplings between the electronic and structural degrees of freedom. When combined with ultrafast laser excitation, new phases of matter can result, since far-from-equilibrium excited states are instantaneously populated. Here, we elucidate a general relation between ultrafast non-equilibrium electron dynamics and the size of the characteristic energy gap in a correlated electron material. We show that carrier multiplication via impact ionization can be one of the most important processes in a gapped material, and that the speed of carrier multiplication critically depends on the size of the energy gap. In the case of the charge-density wave material 1T-TiSe2, our data indicate that carrier multiplication and gap dynamics mutually amplify each other, which explains-on a microscopic level-the extremely fast response of this material to ultrafast optical excitation. PMID- 27698342 TI - Comparative survey of the relative impact of mRNA features on local ribosome profiling read density. AB - Ribosome profiling (Ribo-seq), a promising technology for exploring ribosome decoding rates, is characterized by the presence of infrequent high peaks in ribosome footprint density and by long alignment gaps. Here, to reduce the impact of data heterogeneity we introduce a simple normalization method, Ribo-seq Unit Step Transformation (RUST). RUST is robust and outperforms other normalization techniques in the presence of heterogeneous noise. We illustrate how RUST can be used for identifying mRNA sequence features that affect ribosome footprint densities globally. We show that a few parameters extracted with RUST are sufficient for predicting experimental densities with high accuracy. Importantly the application of RUST to 30 publicly available Ribo-seq data sets revealed a substantial variation in sequence determinants of ribosome footprint frequencies, questioning the reliability of Ribo-seq as an accurate representation of local ribosome densities without prior quality control. This emphasizes our incomplete understanding of how protocol parameters affect ribosome footprint densities. PMID- 27698343 TI - Green tea reduces body fat via upregulation of neprilysin. AB - BACKGROUND/OBJECTIVE: Consumption of green tea has become increasingly popular, particularly because of claimed reduction in body weight. We recently reported that animals with pharmacological inhibition (by candoxatril) or genetic absence of the endopeptidase neprilysin (NEP) develop an obese phenotype. We now investigated the effect of green tea extract (in drinking water) on body weight and body composition and the mediating role of NEP. SUBJECTS/METHODS: To elucidate the role of NEP in mediating the beneficial effects of green tea extract, 'Berlin fat mice' or NEP-deficient mice and their age- and gender matched wild-type controls received the extract in two different doses (300 or 600 mg kg-1 body weight per day) in the drinking water. RESULTS: In 'Berlin fat mice', 51 days of green tea treatment did not only prevent fat accumulation (control: day 0: 30.5% fat, day 51: 33.1%; NS) but also reduced significant body fat (green tea: day 0: 27.8%, day 51: 20.9%, P<0.01) and body weight below the initial levels. Green tea reduced food intake. This was paralleled by a selective increase in peripheral (in kidney 17%, in intestine 92%), but not central NEP expression and activity, leading to downregulation of orexigens (like galanin and neuropeptide Y (NPY)) known to be physiological substrates of NEP. Consequently, in NEP-knockout mice, green tea extract failed to reduce body fat/weight. CONCLUSIONS: Our data generate experimental proof for the assumed effects of green tea on body weight and the key role for NEP in such process, and thus open a new avenue for the treatment of obesity. PMID- 27698345 TI - Weight losses with low-energy formula diets in obese patients with and without type 2 diabetes: systematic review and meta-analysis. AB - AIM: To provide a systematic review, of published data, to compare weight losses following very low calorie (<800 kcal per day VLCD) or low-energy liquid-formula (>800 kcal per day LELD) diets, in people with and without type 2 diabetes mellitus (T2DM). METHODS: Systematic electronic searches of Medline (1946-2015) and Embase (1947-2015) to identify published studies using formula total diet replacement diets (VLCD/LELD). Random effects meta-analysis using weighted mean difference (WMD) in body weight between groups (with and without diabetes) as the summary estimate. RESULTS: Final weight loss, in the five included studies, weighted for study sizes, (n=569, mean BMI=35.5-42.6 kg/m2), was not significantly different between participants with and without T2DM: -1.2 kg; 95% CI: -4.1 to 1.6 kg). Rates of weight loss were also similar in the two groups 0.6 kg per week (T2DM) and 0.5 kg per week (no diabetes), and for VLCD (<800 kcal per day) and LELD (>800 kcal per day). CONCLUSIONS: Weight losses with liquid formula diets are very similar for VLCD and LELD and for obese subjects with or without T2DM. They can potentially achieve new weight loss/ maintenance targets of >15-20% for people with severe and medically complicated obesity. PMID- 27698344 TI - Maternal vitamin D beneficially programs metabolic, gut and bone health of mouse male offspring in an obesogenic environment. AB - BACKGROUND/OBJECTIVES: Vitamin D is an anti-inflammatory nutrient and a determinant of bone health. Some prospective studies suggest that maternal vitamin D status is positively associated with offspring bone mass. We found that serum concentrations of lipopolysaccharide (LPS), an inflammatory molecule related to adiposity, insulin resistance and bone resorption, is lower in healthy mouse offspring exposed to high dietary vitamin D during pregnancy and lactation. LPS reaches the circulation via the gut. This study investigated whether maternal vitamin D programs metabolic, gut and bone health of male offspring in an obesogenic environment. METHODS: C57BL/6J dams received an AIN-93G diet with high (H) or low (L) vitamin D during pregnancy and lactation. At weaning, offspring remained on their dam's vitamin D level (LL or HH) or were switched (LH or HL) and fed a high fat (44.2%) and sucrose (19.8%) diet. Glucose response, adiposity, systemic inflammation (LPS, cytokines), intestinal permeability and mass, strength and microarchitecture of trabecular and cortical bone were assessed in 7 month-old male offsprings. RESULTS: Higher maternal dietary vitamin D resulted in lower intestinal permeability (fecal albumin, P=0.010) and benefited trabecular but not cortical bone structure at the distal femur (higher trabecular number, P=0.022; less trabecular separation, P=0.015) and lumbar vertebra 2 (bone volume/total volume%, P=0.049). Higher maternal and offspring vitamin D resulted in lower fasting glucose (HH versus LL, P=0.039) and serum LPS concentrations (dam diet, P=0.011; pup diet, P=0.002). Higher offspring vitamin D resulted in lower epididymal fat pad relative weight (P=0.006). The serum concentrations of IL-6 and TNF-alpha did not differ among groups. CONCLUSIONS: Maternal dietary vitamin D beneficially programs intestinal permeability and systemic LPS concentration, which is accompanied by stronger trabecular bone in an obesogenic environment. Thus, the gut may mediate vitamin D effects. Moreover, optimizing vitamin D in early life may be critical for later health. PMID- 27698347 TI - Body composition-derived BMI cut-offs for overweight and obesity in Indians and Creoles of Mauritius: comparison with Caucasians. AB - BACKGROUND AND AIMS: Global estimates of overweight and obesity prevalence are based on the World Health Organisation (WHO) body mass index (BMI) cut-off values of 25 and 30 kg m-2, respectively. To validate these BMI cut-offs for adiposity in the island population of Mauritius, we assessed the relationship between BMI and measured body fat mass in this population according to gender and ethnicity. METHODS: In 175 young adult Mauritians (age 20-42 years) belonging to the two main ethnic groups-Indians (South Asian descent) and Creoles (African/Malagasy descent), body weight, height and waist circumference (WC) were measured, total body fat assessed by deuterium oxide (D2O) dilution and trunk (abdominal) fat by segmental bioimpedance analysis. RESULTS: Compared to body fat% predicted from BMI using Caucasian-based equations, body fat% assessed by D2O dilution in Mauritians was higher by 3-5 units in Indian men and women as well as in Creole women, but not in Creole men. This gender-specific ethnic difference in body composition between Indians and Creoles is reflected in their BMI-Fat% relationships, as well as in their WC-Trunk Fat% relationships. Overall, WHO BMI cut-offs of 25 and 30 kg m-2 for overweight and obesity, respectively, seem valid only for Creole men (~24 and 29.5, respectively), but not for Creole women whose BMI cut-offs are 2-4 units lower (21-22 for overweight; 27-28 for obese) nor for Indian men and women whose BMI cut-offs are 3-4 units lower (21-22 for overweight; 26-27 for obese). CONCLUSIONS: The use of BMI cut-off points for classifying overweight and obesity need to take into account both ethnicity and gender to avoid gross adiposity status misclassification in this population known to be at high risk for type-2 diabetes and cardiovascular diseases. This is particularly of importance in obesity prevention strategies both in clinical medicine and public health. PMID- 27698346 TI - Relevance of omental pericellular adipose tissue collagen in the pathophysiology of human abdominal obesity and related cardiometabolic risk. AB - BACKGROUND: Adipose tissue fibrosis is a relatively new notion and its relationship with visceral obesity and cardiometabolic alterations remains unclear, particularly in moderate obesity. OBJECTIVE: Our objective was to examine if total and pericellular collagen accumulation are relevant for the pathophysiology of visceral obesity and related cardiometabolic risk. SUBJECTS AND METHODS: Surgical omental (OM) and subcutaneous (SC) fat samples were obtained in 56 women (age: 47.2+/-5.8 years; body mass index (BMI): 27.1+/-4.4 kg/m2). Body composition and fat distribution were measured by dual-energy X-ray absorptiometry and computed tomography, respectively. Total and pericellular collagen were measured using picrosirius red staining. CD68+ cells (total macrophages) and CD163+ cells (M2-macrophages) were identified using immunohistochemistry. RESULTS: We found that only pericellular collagen percentage, especially in OM fat, was associated with higher BMI, body fat mass and adipose tissue areas as well as lower radiologic attenuation of visceral adipose tissue and altered cardiometabolic risk variables. Strong correlations between peri-adipocyte collagen percentage and total or M2-macrophage percentages were observed in both depots. Total collagen percentage in either compartment was not related to adiposity, fat distribution or cardiometabolic risk. CONCLUSIONS: As opposed to whole tissue-based assessments of adipose tissue fibrosis, collagen deposition around the adipocyte, especially in the OM fat compartment is related to total and regional adiposity as well as altered cardiometabolic risk profile.

AB - Meeting the high demand for lanthanide-doped luminescent nanocrystals across a broad range of fields hinges upon the development of a robust synthetic protocol that provides rapid, just-in-time nanocrystal preparation. However, to date, almost all lanthanide-doped luminescent nanomaterials have relied on direct synthesis requiring stringent controls over crystal nucleation and growth at elevated temperatures. Here we demonstrate the use of a cation exchange strategy for expeditiously accessing large classes of such nanocrystals. By combining the process of cation exchange with energy migration, the luminescence properties of the nanocrystals can be easily tuned while preserving the size, morphology and crystal phase of the initial nanocrystal template. This post-synthesis strategy enables us to achieve upconversion luminescence in Ce3+ and Mn2+-activated hexagonal-phased nanocrystals, opening a gateway towards applications ranging from chemical sensing to anti-counterfeiting. PMID- 27698351 TI - Contextuality without nonlocality in a superconducting quantum system. AB - Classical realism demands that system properties exist independently of whether they are measured, while noncontextuality demands that the results of measurements do not depend on what other measurements are performed in conjunction with them. The Bell-Kochen-Specker theorem states that noncontextual realism cannot reproduce the measurement statistics of a single three-level quantum system (qutrit). Noncontextual realistic models may thus be tested using a single qutrit without relying on the notion of quantum entanglement in contrast to Bell inequality tests. It is challenging to refute such models experimentally, since imperfections may introduce loopholes that enable a realist interpretation. Here we use a superconducting qutrit with deterministic, binary-outcome readouts to violate a noncontextuality inequality while addressing the detection, individual-existence and compatibility loopholes. This evidence of state dependent contextuality also demonstrates the fitness of superconducting quantum circuits for fault-tolerant quantum computation in surface-code architectures, currently the most promising route to scalable quantum computing. PMID- 27698352 TI - Nanoscale structural oscillations in perovskite oxides induced by oxygen evolution. AB - Understanding the interaction between water and oxides is critical for many technological applications, including energy storage, surface wetting/self cleaning, photocatalysis and sensors. Here, we report observations of strong structural oscillations of Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) in the presence of both H2O vapour and electron irradiation using environmental transmission electron microscopy. These oscillations are related to the formation and collapse of gaseous bubbles. Electron energy-loss spectroscopy provides direct evidence of O2 formation in these bubbles due to the incorporation of H2O into BSCF. SrCoO3 delta was found to exhibit small oscillations, while none were observed for La0.5Sr0.5CoO3-delta and LaCoO3. The structural oscillations of BSCF can be attributed to the fact that its oxygen 2p-band centre is close to the Fermi level, which leads to a low energy penalty for oxygen vacancy formation, high ion mobility, and high water uptake. This work provides surprising insights into the interaction between water and oxides under electron-beam irradiation. PMID- 27698350 TI - A regulatory circuit of miR-125b/miR-20b and Wnt signalling controls glioblastoma phenotypes through FZD6-modulated pathways. AB - Molecularly defined subclassification is associated with phenotypic malignancy of glioblastoma (GBM). However, current understanding of the molecular basis of subclass conversion that is often involved in GBM recurrence remain rudimentary at best. Here we report that canonical Wnt signalling that is active in proneural (PN) but inactive in mesenchymal (MES) GBM, along with miR-125b and miR-20b that are expressed at high levels in PN compared with MES GBM, comprise a regulatory circuit involving TCF4-miR-125b/miR-20b-FZD6. FZD6 acts as a negative regulator of this circuit by activating CaMKII-TAK1-NLK signalling, which, in turn, attenuates Wnt pathway activity while promoting STAT3 and NF-kappaB signalling that are important regulators of the MES-associated phenotype. These findings are confirmed by targeting differentially enriched pathways in PN versus MES GBM that results in inhibition of distinct GBM subtypes. Correlative expressions of the components of this circuit are prognostic relevant for clinical GBM. Our findings provide insights for understanding GBM pathogenesis and for improving treatment of GBM. PMID- 27698353 TI - Complete prevention of blood loss with self-sealing haemostatic needles. AB - Bleeding is largely unavoidable following syringe needle puncture of biological tissues and, while inconvenient, this typically causes little or no harm in healthy individuals. However, there are certain circumstances where syringe injections can have more significant side effects, such as uncontrolled bleeding in those with haemophilia, coagulopathy, or the transmission of infectious diseases through contaminated blood. Herein, we present a haemostatic hypodermic needle able to prevent bleeding following tissue puncture. The surface of the needle is coated with partially crosslinked catechol-functionalized chitosan that undergoes a solid-to-gel phase transition in situ to seal punctured tissues. Testing the capabilities of these haemostatic needles, we report complete prevention of blood loss following intravenous and intramuscular injections in animal models, and 100% survival in haemophiliac mice following syringe puncture of the jugular vein. Such self-sealing haemostatic needles and adhesive coatings may therefore help to prevent complications associated with bleeding in more clinical settings. PMID- 27698355 TI - Non-Hermitian engineering of single mode two dimensional laser arrays. AB - A new scheme for building two dimensional laser arrays that operate in the single supermode regime is proposed. This is done by introducing an optical coupling between the laser array and lossy pseudo-isospectral chains of photonic resonators. The spectrum of this discrete reservoir is tailored to suppress all the supermodes of the main array except the fundamental one. This spectral engineering is facilitated by employing the Householder transformation in conjunction with discrete supersymmetry. The proposed scheme is general and can in principle be used in different platforms such as VCSEL arrays and photonic crystal laser arrays. PMID- 27698354 TI - Direct-indirect character of the bandgap in methylammonium lead iodide perovskite. AB - Metal halide perovskites such as methylammonium lead iodide (CH3NH3PbI3) are generating great excitement due to their outstanding optoelectronic properties, which lend them to application in high-efficiency solar cells and light-emission devices. However, there is currently debate over what drives the second-order electron-hole recombination in these materials. Here, we propose that the bandgap in CH3NH3PbI3 has a direct-indirect character. Time-resolved photo-conductance measurements show that generation of free mobile charges is maximized for excitation energies just above the indirect bandgap. Furthermore, we find that second-order electron-hole recombination of photo-excited charges is retarded at lower temperature. These observations are consistent with a slow phonon-assisted recombination pathway via the indirect bandgap. Interestingly, in the low temperature orthorhombic phase, fast quenching of mobile charges occurs independent of the temperature and photon excitation energy. Our work provides a new framework to understand the optoelectronic properties of metal halide perovskites and analyse spectroscopic data. PMID- 27698356 TI - Three representations of the Ising model. AB - Statistical models that analyse (pairwise) relations between variables encompass assumptions about the underlying mechanism that generated the associations in the observed data. In the present paper we demonstrate that three Ising model representations exist that, although each proposes a distinct theoretical explanation for the observed associations, are mathematically equivalent. This equivalence allows the researcher to interpret the results of one model in three different ways. We illustrate the ramifications of this by discussing concepts that are conceived as problematic in their traditional explanation, yet when interpreted in the context of another explanation make immediate sense. PMID- 27698357 TI - Impact of high fat diet on long non-coding RNAs and messenger RNAs expression in the aortas of ApoE(-/-) mice. AB - Atherosclerosis is a chronic multifactorial inflammatory disease with high prevalence worldwide, and has become the leading cause of death. The present study was designed to investigate the impact of high-fat diet on ApoE(-/-) mice exhibiting atherosclerosis by detecting the genome-wide expression profile of lncRNAs and mRNAs. A total of 354 differentially expressed lncRNAs were identified (>=2.0 folds). Simultaneously, 357 differentially expressed mRNAs from the same chip were found. The expression differences of lncRNAs and mRNAs were consistent in both qPCR and microarray detection. Annotation results of the mRNAs which correlated with lncRNAs showed that the commonly related pathways were metabolism and inflammation. Hypergeometric distribution analysis indicated that the differentially expressed lncRNAs had been mostly regulated by transcription factors (TFs) such as Myod1, Rxra, Pparg, Tcf3, etc. Additional lncRNA-target-TFs network analysis was conducted for the top 20 differentially expressed lncRNAs. The results indicated Hnf4a, Ppara, Vdr, and Runx3 as the TFs most likely to regulate the production of these lncRNAs, and might play roles in inflammatory and metabolic processes in atherosclerosis. In a nutshell, the present study identified a panel of dysregulated lncRNAs and mRNAs that may be potential biomarkers or drug targets relevant to the high-fat diet related atherogenesis. PMID- 27698359 TI - Observation of a hybrid state of Tamm plasmons and microcavity exciton polaritons. AB - We present evidence for the existence of a hybrid state of Tamm plasmons and microcavity exciton polaritons in a II-VI material based microcavity sample covered with an Ag metal layer. The bare cavity mode shows a characteristic anticrossing with the Tamm-plasmon mode, when microreflectivity measurements are performed for different detunings between the Tamm plasmon and the cavity mode. When the Tamm-plasmon mode is in resonance with the cavity polariton four hybrid eigenstates are observed due to the coupling of the cavity-photon mode, the Tamm plasmon mode, and the heavy- and light-hole excitons. If the bare Tamm-plasmon mode is tuned, these resonances will exhibit three anticrossings. Experimental results are in good agreement with calculations based on the transfer matrix method as well as on the coupled-oscillators model. The lowest hybrid eigenstate is observed to be red shifted by about 13 meV with respect to the lower cavity polariton state when the Tamm plasmon is resonantly coupled with the cavity polariton. This spectral shift which is caused by the metal layer can be used to create a trapping potential channel for the polaritons. Such channels can guide the polariton propagation similar to one-dimensional polariton wires. PMID- 27698358 TI - In-vivo Imaging of Magnetic Fields Induced by Transcranial Direct Current Stimulation (tDCS) in Human Brain using MRI. AB - Transcranial direct current stimulation (tDCS) is an emerging non-invasive neuromodulation technique that applies mA currents at the scalp to modulate cortical excitability. Here, we present a novel magnetic resonance imaging (MRI) technique, which detects magnetic fields induced by tDCS currents. This technique is based on Ampere's law and exploits the linear relationship between direct current and induced magnetic fields. Following validation on a phantom with a known path of electric current and induced magnetic field, the proposed MRI technique was applied to a human limb (to demonstrate in-vivo feasibility using simple biological tissue) and human heads (to demonstrate feasibility in standard tDCS applications). The results show that the proposed technique detects tDCS induced magnetic fields as small as a nanotesla at millimeter spatial resolution. Through measurements of magnetic fields linearly proportional to the applied tDCS current, our approach opens a new avenue for direct in-vivo visualization of tDCS target engagement. PMID- 27698360 TI - Repeated superovulation may affect mitochondrial functions of cumulus cells in mice. AB - Controlled ovarian stimulation by exogenous gonadotrophins is a key procedure during the in vitro fertilization cycle to obtain a sufficient number of oocytes in humans. Previous studies demonstrated that repeated superovulation had deleterious effects on the ovaries. However, whether repeated superovulation adversely affects the mitochondrial functions of cumulus cells remains unclear. In this study, mice were divided into three groups: superovulation once (R1); superovulation three times (R3), and superovulation five times (R5). We evaluated the effects of repeated superovulation on mitochondrial DNA copies (mtDNA) and observed decreased mtDNA copies per cell with increasing number of superovulation cycles. Further, we investigated the DNA methylation status in exon 2 and the mRNA expression level of nuclear-encoded DNA polymerase gamma A (PolgA). The results showed that the DNA methylation levels of PolgA in R1 and R5 were slightly lower than in R3. Additionally, the altered DNA methylation in PolgA coincided with the changes in PolgA expression in cumulus cells. We also found that the mRNA expression of COX1, CYTB, ND2, and ND4 was altered by repeated superovulation in cumulus cells. Thus, repeated superovulation had adverse effects on mitochondrial function. PMID- 27698361 TI - Short-term Effects of Risperidone Monotherapy on Spontaneous Brain Activity in First-episode Treatment-naive Schizophrenia Patients: A Longitudinal fMRI Study. AB - It is unclear whether abnormal spontaneous neural activation patterns found in chronic schizophrenia patients (CSP) are part of the pathogenesis of disease, consequences of chronic illness, or effects of antipsychotic treatment. We performed a longitudinal resting-state functional magnetic resonance imaging (fMRI) study in 42 treatment-naive first-episode schizophrenia patients (FESP) at baseline and then after 8-weeks of risperidone monotherapy, and compared the findings to 38 healthy volunteers. Spontaneous brain activity was quantified using the fractional amplitude of low-frequency fluctuations (fALFF) and regional homogeneity (ReHo) and compared between patients and controls. Pretreatment, patients exhibited higher fALFF in left caudate compared with controls. After treatment, patients had elevated fALFF in bilateral putamen and right caudate, and increased ReHo in right caudate and left putamen. Greater increase of fALFF in the left putamen correlated with less improvement in positive symptoms. Thus, abnormalities of spontaneous neural activity in chronic schizophrenia is at least partly due to a medication effect. The observed post-treatment increase in striatal intrinsic activity may reflect counter-therapeutic functional adaptation to dopamine D2 receptor occupancy required for medication effects on psychosis. PMID- 27698362 TI - GPR30 regulates diet-induced adiposity in female mice and adipogenesis in vitro. AB - Recent studies showed that GPR30, a seven-transmembrane G-protein-coupled receptor, is a novel estrogen receptor (ER) that mediates some biological events elicited by estrogen in several types of cancer cells. However, its physiological or pathological role in vivo is unclear. Here, we show that GPR30 knockout (GPRKO) female mice were protected from high-fat diet (HFD)-induced obesity, blood glucose intolerance, and insulin resistance. The decreased body weight gain in GPRKO female mice is due to the reduction in body fat mass. These effects occurred in the absence of significant changes in food intake, intestinal fat absorption, triglyceride metabolism, or energy expenditure. However, GPR30 had no significant metabolic effects in male mice fed the HFD and both sexes of mice fed a chow diet. Further, GPR30 expression levels in fat tissues of WT obese female mice were greatly increased, whereas ERalpha and beta expression was not altered. Deletion of GPR30 reduced adipogenic differentiation of adipose tissue-derived stromal cells. Conversely, activation of GPR30 enhanced adipogenic differentiation of 3T3-L1 preadipocytes. These findings provide evidence for the first time that GPR30 promotes adipogenesis and therefore the development of obesity in female mice exposed to excess fat energy. PMID- 27698363 TI - Comparing performance of modern genotype imputation methods in different ethnicities. AB - A variety of modern software packages are available for genotype imputation relying on advanced concepts such as pre-phasing of the target dataset or utilization of admixed reference panels. In this study, we performed a comprehensive evaluation of the accuracy of modern imputation methods on the basis of the publicly available POPRES samples. Good quality genotypes were masked and re-imputed by different imputation frameworks: namely MaCH, IMPUTE2, MaCH-Minimac, SHAPEIT-IMPUTE2 and MaCH-Admix. Results were compared to evaluate the relative merit of pre-phasing and the usage of admixed references. We showed that the pre-phasing framework SHAPEIT-IMPUTE2 can overestimate the certainty of genotype distributions resulting in the lowest percentage of correctly imputed genotypes in our case. MaCH-Minimac performed better than SHAPEIT-IMPUTE2. Pre phasing always reduced imputation accuracy. IMPUTE2 and MaCH-Admix, both relying on admixed-reference panels, showed comparable results. MaCH showed superior results if well-matched references were available (Nei's GST <= 0.010). For small to medium datasets, frameworks using genetically closest reference panel are recommended if the genetic distance between target and reference data set is small. Our results are valid for small to medium data sets. As shown on a larger data set of population based German samples, the disadvantage of pre-phasing decreases for larger sample sizes. PMID- 27698364 TI - Vitamin D Supplementation for Patients with Dry Eye Syndrome Refractory to Conventional Treatment. AB - This study investigated the effect of vitamin D supplementation in patients with dry eye syndrome (DES) refractory to conventional treatment with vitamin D deficiency. A total of 105 patients with DES refractory to conventional treatment and vitamin D deficiency that was treated with an intramuscular injection of cholecalciferol (200,000 IU). Serum 25-hydroxyvitamin D (25(OH)D) levels were measured. Eye discomfort was assessed using ocular surface disease index (OSDI) and visual analogue pain score (VAS). Tear break-up time (TBUT), fluorescein staining score (FSS), eyelid margin hyperemia, and tear secretion test were measured before treatment, and 2, 6, and 10 weeks after vitamin D supplementation. Mean serum 25(OH)D level was 10.52 +/- 4.61 ng/mL. TBUT, and tear secretion test showed an improvement at 2 and 6 weeks after vitamin D supplementation compared to pretreatment values (p < 0.05 for all, paired t test). Eyelid margin hyperemia and the severity of symptoms showed improvement at 2, 6, and 10 weeks after vitamin D supplementation (p < 0.05 for all). Compared to pre-treatment values, FSS, OSDI and VAS were decreased at 2 weeks (p < 0.05 for all). In conclusion, vitamin D supplementation is effective and useful in the treatment of patients with DES refractory to conventional treatment and with vitamin D deficiency. PMID- 27698365 TI - Non-invasive modulation of somatosensory evoked potentials by the application of static magnetic fields over the primary and supplementary motor cortices. AB - This study was performed to investigate the possibility of non-invasive modulation of SEPs by the application of transcranial static magnetic field stimulation (tSMS) over the primary motor cortex (M1) and supplementary motor cortex (SMA), and to measure the strength of the NdFeB magnetic field by using a gaussmeter. An NdFeB magnet or a non-magnetic stainless steel cylinder (for sham stimulation) was settled on the scalp over M1 and SMA of 14 subjects for periods of 15 min. SEPs following right median nerve stimulation were recorded before and immediately after, 5 min after, and 10 min after tSMS from sites C3' and F3. Amplitudes of the N33 component of SEPs at C3' significantly decreased immediately after tSMS over M1 by up to 20%. However, tSMS over the SMA did not affect the amplitude of any of the SEP components. At a distance of 2-3 cm (rough depth of the cortex), magnetic field strength was in the range of 110-190 mT. Our results that tSMS over M1 can reduce the amplitude of SEPs are consistent with those of low-frequency repeated TMS and cathodal tDCS studies. Therefore, tSMS could be a useful tool for modulating cortical somatosensory processing. PMID- 27698366 TI - Histone acetylation dependent energy landscapes in tri-nucleosome revealed by residue-resolved molecular simulations. AB - Histone tail acetylation is a key epigenetic marker that tends to open chromatin folding and activate transcription. Despite intensive studies, precise roles of individual lysine acetylation in chromatin folding have only been poorly understood. Here, we revealed structural dynamics of tri-nucleosomes with several histone tail acetylation states and analyzed histone tail interactions with DNA by performing molecular simulations at an unprecedentedly high resolution. We found versatile acetylation-dependent landscapes of tri-nucleosome. The H4 and H2A tail acetylation reduced the contact between the first and third nucleosomes mediated by the histone tails. The H3 tail acetylation reduced its interaction with neighboring linker DNAs resulting in increase of the distance between consecutive nucleosomes. Notably, two copies of the same histone in a single nucleosome have markedly asymmetric interactions with DNAs, suggesting specific pattern of nucleosome docking albeit high inherent flexibility. Estimated transcription factor accessibility was significantly high for the H4 tail acetylated structures. PMID- 27698367 TI - MiR-125a-3p timely inhibits oligodendroglial maturation and is pathologically up regulated in human multiple sclerosis. AB - In the mature central nervous system (CNS), oligodendrocytes provide support and insulation to axons thanks to the production of a myelin sheath. During their maturation to myelinating cells, oligodendroglial precursors (OPCs) follow a very precise differentiation program, which is finely orchestrated by transcription factors, epigenetic factors and microRNAs (miRNAs), a class of small non-coding RNAs involved in post-transcriptional regulation. Any alterations in this program can potentially contribute to dysregulated myelination, impaired remyelination and neurodegenerative conditions, as it happens in multiple sclerosis (MS). Here, we identify miR-125a-3p, a developmentally regulated miRNA, as a new actor of oligodendroglial maturation, that, in the mammalian CNS regulates the expression of myelin genes by simultaneously acting on several of its already validated targets. In cultured OPCs, over-expression of miR-125a-3p by mimic treatment impairs while its inhibition with an antago-miR stimulates oligodendroglial maturation. Moreover, we show that miR-125a-3p levels are abnormally high in the cerebrospinal fluid of MS patients bearing active demyelinating lesions, suggesting that its pathological upregulation may contribute to MS development, at least in part by blockade of OPC differentiation leading to impaired repair of demyelinated lesions. PMID- 27698368 TI - "RaMassays": Synergistic Enhancement of Plasmon-Free Raman Scattering and Mass Spectrometry for Multimodal Analysis of Small Molecules. AB - SiO2/TiO2 core/shell (T-rex) beads were exploited as "all-in-one" building-block materials to create analytical assays that combine plasmon-free surface enhanced Raman scattering (SERS) and surface assisted laser desorption/ionization (SALDI) mass spectrometry (RaMassays). Such a multi-modal approach relies on the unique optical properties of T-rex beads, which are able to harvest and manage light in both UV and Vis range, making ionization and Raman scattering more efficient. RaMassays were successfully applied to the detection of small (molecular weight, M.W. <400 Da) molecules with a key relevance in biochemistry and pharmaceutical analysis. Caffeine and cocaine were utilized as molecular probes to test the combined SERS/SALDI response of RaMassays, showing excellent sensitivity and reproducibility. The differentiation between amphetamine/ephedrine and theophylline/theobromine couples demonstrated the synergistic reciprocal reinforcement of SERS and SALDI. Finally, the conversion of L-tyrosine in L-DOPA was utilized to probe RaMassays as analytical tools for characterizing reaction intermediates without introducing any spurious effects. RaMassays exhibit important advantages over plasmonic nanoparticles in terms of reproducibility, absence of interference and potential integration in multiplexed devices. PMID- 27698369 TI - Smartphone-Based Accurate Analysis of Retinal Vasculature towards Point-of-Care Diagnostics. AB - Retinal vasculature analysis is important for the early diagnostics of various eye and systemic diseases, making it a potentially useful biomarker, especially for resource-limited regions and countries. Here we developed a smartphone-based retinal image analysis system for point-of-care diagnostics that is able to load a fundus image, segment retinal vessels, analyze individual vessel width, and store or uplink results. The proposed system was not only evaluated on widely used public databases and compared with the state-of-the-art methods, but also validated on clinical images directly acquired with a smartphone. An Android app is also developed to facilitate on-site application of the proposed methods. Both visual assessment and quantitative assessment showed that the proposed methods achieved comparable results to the state-of-the-art methods that require high standard workstations. The proposed system holds great potential for the early diagnostics of various diseases, such as diabetic retinopathy, for resource limited regions and countries. PMID- 27698371 TI - TM4 of the glutamate transporter GLT-1 experiences substrate-induced motion during the transport cycle. AB - Excitatory amino acid transporter 2 (EAAT2), also known as glial glutamate transporter type 1 (GLT-1), plays an important role in maintaining the extracellular glutamate concentrations below neurotoxic levels. The highly conserved TM2 transmembrane domain of GLT-1 maintains a stable position during the transport cycle; however, the effect of the transport cycle on the topology of TM4 in not well established. To further reveal the function of TM4, two cysteine pairs between TM2 and TM4 were introduced using site-directed mutagenesis. A significant decrease of transport activity was observed in the I93C/V241C and I97C/V241C mutants upon application of the oxidative cross-linking reagent, copper (II) (1,10-phenanthroline)3 (CuPh), which suggests that a conformational shift is essential for transporter activity. Furthermore, the decrease in activity by CuPh crosslinking was enhanced in external media with glutamate or potassium, which suggests that TM2 and TM4 assume closer proximity in the inward-facing conformation of the transporter. Our results suggest that the TM4 domain of GLT-1, and potentially other glutamate transporters, undergoes a complex conformational shift during substrate translocation, which involves an increase in the proximity of the TM2 and TM4 domains in the inward-facing conformation. PMID- 27698372 TI - Bimodal Control of Heat Transport at Graphene-Metal Interfaces Using Disorder in Graphene. AB - Thermal energy transport across the interfaces of physically and chemically modified graphene with two metals, Al and Cu, was investigated by measuring thermal conductance using the time-domain thermoreflectance method. Graphene was processed using a He2+ ion-beam with a Gaussian distribution or by exposure to ultraviolet/O3, which generates structural or chemical disorder, respectively. Hereby, we could monitor changes in the thermal conductance in response to varying degrees of disorder. We find that the measured conductance increases as the density of the physical disorder increases, but undergoes an abrupt modulation with increasing degrees of chemical modification, which decreases at first and then increases considerably. Moreover, we find that the conductance varies inverse proportionally to the average distance between the structural defects in the graphene, implying a strong in-plane influence of phonon kinetics on interfacial heat flow. We attribute the bimodal results to an interplay between the distinct effects on graphene's vibrational modes exerted by graphene modification and by the scattering of modes. PMID- 27698370 TI - Attenuation of Na/K-ATPase Mediated Oxidant Amplification with pNaKtide Ameliorates Experimental Uremic Cardiomyopathy. AB - We have previously reported that the sodium potassium adenosine triphosphatase (Na/K-ATPase) can effect the amplification of reactive oxygen species. In this study, we examined whether attenuation of oxidant stress by antagonism of Na/K ATPase oxidant amplification might ameliorate experimental uremic cardiomyopathy induced by partial nephrectomy (PNx). PNx induced the development of cardiac morphological and biochemical changes consistent with human uremic cardiomyopathy. Both inhibition of Na/K-ATPase oxidant amplification with pNaKtide and induction of heme oxygenase-1 (HO-1) with cobalt protoporphyrin (CoPP) markedly attenuated the development of phenotypical features of uremic cardiomyopathy. In a reversal study, administration of pNaKtide after the induction of uremic cardiomyopathy reversed many of the phenotypical features. Attenuation of Na/K-ATPase oxidant amplification may be a potential strategy for clinical therapy of this disorder. PMID- 27698373 TI - Identification of drought-responsive microRNAs and their targets in Ammopiptanthus mongolicus by using high-throughput sequencing. AB - MicroRNAs (miRNAs) regulate target gene expression to modulate plant growth, development, and biotic and abiotic stress response at the post-transcriptional level. Ammopiptanthus mongolicus, an ecologically important desert plant, is increasingly used as a model for studying stress tolerance in plants. The miRNA mediated gene regulatory network might remarkably contribute to the high stress tolerance of A. mongolicus. However, a genome-wide identification of miRNAs and their targets is still lacking in A. mongolicus. In this study, 170 conserved and 156 non-conserved miRNAs were identified in A. mongolicus. We experimentally identified 298 miRNA-target pairs from the degradome data. Quantitative real-time polymerase chain reaction analyses identified 28 drought-responsive miRNAs in leaves and 15 in roots. Some characteristics of the miRNA-mediated regulatory network were found in A. mongolicus. Multiple miRNAs, including 2 newly identified non-conserved miRNAs, miR-P11 and miR-P14, generated from the precursors of miR169, were found to be involved in drought stress response. Further, miR2118 and miR858 participated in drought stress response by up regulating OZF1 gene and certain MYB genes that were involved in the regulation of flavonol biosynthesis in A. mongolicus. The findings of this study might provide new insights for understanding the functions of miRNA in stress response in plants.

AB - Sleep habits are associated with stroke in western populations, but this relation has been rarely investigated in China. Moreover, the differences among stroke subtypes remain unclear. This study aimed to explore the associations of total stroke, including ischemic and hemorrhagic type, with sleep habits of a population in southern China. We performed a case-control study in patients admitted to the hospital with first stroke and community control subjects. A total of 333 patients (n = 223, 67.0%, with ischemic stroke; n = 110, 23.0%, with hemorrhagic stroke) and 547 controls were enrolled in the study. Participants completed a structured questionnaire to identify sleep habits and other stroke risk factors. Least absolute shrinkage and selection operator (Lasso) and multiple logistic regression were performed to identify risk factors of disease. Incidence of stroke, and its subtypes, was significantly associated with snorting/gasping, snoring, sleep duration, and daytime napping. Snorting/gasping was identified as an important risk factor in the Lasso logistic regression model (Lasso' beta = 0.84), and the result was proven to be robust. This study showed the association between stroke and sleep habits in the southern Chinese population and might help in better detecting important sleep-related factors for stroke risk.

AB - In the fight against drug-resistant bacteria, accurate and high-throughput detection is essential. Here, a bimaterial microcantilever with an embedded microfluidic channel with internal surfaces chemically or physically functionalized with receptors selectively captures the bacteria passing through the channel. Bacterial adsorption inside the cantilever results in changes in the resonance frequency (mass) and cantilever deflection (adsorption stress). The excitation of trapped bacteria using infrared radiation (IR) causes the cantilever to deflect in proportion to the infrared absorption of the bacteria, providing a nanomechanical infrared spectrum for selective identification. We demonstrate the in situ detection and discrimination of Listeria monocytogenes at a concentration of single cell per MUl. Trapped Escherichia coli in the microchannel shows a distinct nanomechanical response when exposed to antibiotics. This approach, which combines enrichment with three different modes of detection, can serve as a platform for the development of a portable, high throughput device for use in the real-time detection of bacteria and their response to antibiotics.

AB - Pinelliae Rhizoma (PR) is a commonly used Chinese medicinal herb, but it has been frequently reported about its toxicity. According to the traditional Chinese medicine theory, processing can reduce the toxicity of the herbs. Here, we aim to determine if processing reduces the toxicity of raw PR, and to explore the underlying mechanisms of raw PR-induced toxicities and the toxicity-reducing effect of processing. Biochemical and histopathological approaches were used to evaluate the toxicities of raw and processed PR. Rat serum metabolites were analyzed by LC-TOF-MS. Ingenuity pathway analysis of the metabolomics data highlighted the biological pathways and network functions involved in raw PR induced toxicities and the toxicity-reducing effect of processing, which were verified by molecular approaches. Results showed that raw PR caused cardiotoxicity, and processing reduced the toxicity. Inhibition of mTOR signaling and activation of the TGF-beta pathway contributed to raw PR-induced cardiotoxicity, and free radical scavenging might be responsible for the toxicity reducing effect of processing. Our data shed new light on the mechanisms of raw PR-induced cardiotoxicity and the toxicity-reducing effect of processing. This study provides scientific justifications for the traditional processing theory of PR, and should help in optimizing the processing protocol and clinical combinational application of PR.

AB - The natural occurrence of live hybrid offsprings between sheep and goats has been documented in literature, however all the studies have reported the mating of goats with rams, whereas the reciprocal cross was never documented. This study reports on a very rare case of interspecies hybridization occurred between a ewe (2n = 54, XX) and a buck (2n = 60, XY). The hybrid, born in a German flock under natural conditions, is characterised by an intermediate karyotype (2n = 57, XX). The CBA-banding has shown 3 metacentric and 54 acrocentric chromosomes, whereas the GTG- and RBA-banding have revealed that the autosomes involved in the hybrid combination were CHI1, 3; CHI2, 8 and CHI5, 11 corresponding to the metacentric chromosomes OAR1, OAR2 and OAR3. A tri-colour FISH using chromosome paintings and BAC probes has validated this arrangement. A further FISH analysis has been carried out to analyse the telomeres, which showed a normal structure. Nucleolus organiser-bearing chromosomes were identified as pairs OAR1p(CHI3), OAR2q(CHI2), OAR3q(CHI5), OAR4(CHI4) and OAR25(CHI28), and nuclear associations were found. Sex chromosomes were correctly arranged. The odd number of the karyotype might be responsible for a reduced fertility as consequence of the incorrect chromosomal pairing and/or segregation during the meiosis.

AB - We report a composite waveguide fabricated by attaching a coupling aperture to a waveguide. The acoustic impedance of the composite waveguide can be regulated by merely controlling its coupling vibrations, depending on its structure size. By changing the size to adjust the acoustic impedance of the composite waveguide at an impedance-mismatched fluidic interface, tunable sound transmission at the desired frequencies is achieved. The reported composite waveguide provides a new method for sound regulation at a mismatched fluidic interface and has extensive frequency hopping and frequency agility applications in air-water sound communication. PMID- 27698377 TI - Inhibition of Complement Retards Ankylosing Spondylitis Progression. AB - Ankylosing spondylitis (AS) is a chronic axial spondyloarthritis (SpA) resulting in back pain and progressive spinal ankyloses. Currently, there are no effective therapeutics targeting AS largely due to elusive pathogenesis mechanisms, even as potential candidates such as HLA-B27 autoantigen have been identified. Herein, we employed a proteoglycan (PG)-induced AS mouse model together with clinical specimens, and found that the complement system was substantially activated in the spinal bone marrow, accompanied by a remarkable proportion alteration of neutrophils and macrophage in bone marrow and spleen, and by the significant increase of TGF-beta1 in serum. The combined treatment with a bacteria-derived complement inhibitor Efb-C (C-terminal of extracellular fibrinogen-binding protein of Staphylococcus aureus) remarkably retarded the progression of mouse AS by reducing osteoblast differentiation. Furthermore, we demonstrated that two important modulators involved in AS disease, TGF-beta1 and RANKL, were elevated upon in vitro complement attack in osteoblast and/or osteoclast cells. These findings further unravel that complement activation is closely related with the pathogenesis of AS, and suggest that complement inhibition may hold great potential for AS therapy. PMID- 27698380 TI - Survival Motor Neuron (SMN) protein is required for normal mouse liver development. AB - Spinal Muscular Atrophy (SMA) is caused by mutation or deletion of the survival motor neuron 1 (SMN1) gene. Decreased levels of, cell-ubiquitous, SMN protein is associated with a range of systemic pathologies reported in severe patients. Despite high levels of SMN protein in normal liver, there is no comprehensive study of liver pathology in SMA. We describe failed liver development in response to reduced SMN levels, in a mouse model of severe SMA. The SMA liver is dark red, small and has: iron deposition; immature sinusoids congested with blood; persistent erythropoietic elements and increased immature red blood cells; increased and persistent megakaryocytes which release high levels of platelets found as clot-like accumulations in the heart. Myelopoiesis in contrast, was unaffected. Further analysis revealed significant molecular changes in SMA liver, consistent with the morphological findings. Antisense treatment from birth with PMO25, increased lifespan and ameliorated all morphological defects in liver by postnatal day 21. Defects in the liver are evident at birth, prior to motor system pathology, and impair essential liver function in SMA. Liver is a key recipient of SMA therapies, and systemically delivered antisense treatment, completely rescued liver pathology. Liver therefore, represents an important therapeutic target in SMA. PMID- 27698382 TI - Lichen elemental composition distinguishes anthropogenic emissions from dust storm inputs and differs among species: Evidence from Xilinhot, Inner Mongolia, China. AB - To test the applicability of lichens in the biomonitoring of atmospheric elemental deposition in a typical steppe zone of Inner Mongolia, China, six foliose lichens (Physcia aipolia, PA; P. tribacia, PT; Xanthoria elegans, XE; X. mandschurica, XM; Xanthoparmelia camtschadalis, XPC; and Xp. tinctina, XPT) were sampled from the Xilin River Basin, Xilinhot, Inner Mongolia, China. Twenty-five elements (Al, Ba, Cd, Ce, Cr, Cs, Cu, Fe, K, La, Mn, Mo, Na, Ni, P, Pb, Sb, Sc, Sm, Tb, Th, Ti, Tl, V and Zn) in the lichens were analysed using inductively coupled plasma mass spectrometry (ICP-MS). The results show that Cd, Pb and Zn were mainly atmospheric in origin, whereas the other elements were predominantly of crustal origin. Compared with other studies, our data were higher in crustal element concentrations and lower in atmospheric element concentrations, matching with the frequent, severe dust storms and road traffic in the area. The elemental concentrations in lichens are both species- and element-specific, highlighting the importance of species selection for biomonitoring air pollution using lichens. We recommend PT, XE, XM and XPT for monitoring atmospheric deposition of crustal elements; XPC and XPT for Cd and Pb; PA for Cd and Zn; and PT for Cd. PMID- 27698381 TI - The shift of microbial communities and their roles in sulfur and iron cycling in a copper ore bioleaching system. AB - Bioleaching has been employed commercially to recover metals from low grade ores, but the production efficiency remains to be improved due to limited understanding of the system. This study examined the shift of microbial communities and S&Fe cycling in three subsystems within a copper ore bioleaching system: leaching heap (LH), leaching solution (LS) and sediment under LS. Results showed that both LH and LS had higher relative abundance of S and Fe oxidizing bacteria, while S and Fe reducing bacteria were more abundant in the Sediment. GeoChip analysis showed a stronger functional potential for S0 oxidation in LH microbial communities. These findings were consistent with measured oxidation activities to S0 and Fe2+, which were highest by microbial communities from LH, lower by those from LS and lowest form Sediment. Moreover, phylogenetic molecular ecological network analysis indicated that these differences might be related to interactions among microbial taxa. Last but not the least, a conceptual model was proposed, linking the S&Fe cycling with responsible microbial populations in the bioleaching systems. Collectively, this study revealed the microbial community and functional structures in all three subsystems of the copper ore, and advanced a holistic understanding of the whole bioleaching system. PMID- 27698384 TI - Comparative Secretome Analysis Reveals Perturbation of Host Secretion Pathways by a Hypovirus. AB - To understand the impact of a hypovirus infection on the secretome of the chestnut blight fungus, Cryphonectria parasitica, a phytopathogenic filamentous fungus, two-dimensional electrophoresis (2-DE) and isobaric tag for relative and absolute quantitation (iTRAQ) technology were employed to identify and quantify the secreted proteins. A total of 403 unique proteins were identified from the secretome of the wild type virus-free strain EP155. Of these proteins, 329 were predicted to be involved in known secretory pathways and they are primarily composed of metabolic enzymes, biological regulators, responders to stimulus and components involved in plant-pathogen interactions. When infected with the hypovirus CHV1-EP713, 99 proteins were found to be differentially expressed as compared to the wild type strain EP155. These proteins were mainly related to plant cell wall degradation, response to host defense, fungal virulence and intracellular structure. The effects of CHV1 on secreted proteins may reveal a relationship between physiological pathways and hypovirulence. PMID- 27698386 TI - High-Resolution Impedance Manometry Metrics of the Esophagogastric Junction for the Assessment of Treatment Response in Achalasia. AB - OBJECTIVES: We aimed to evaluate the value of novel high-resolution impedance manometry (HRIM) metrics, bolus flow time (BFT), and esophagogastric junction (EGJ) contractile integral (CI), as well as EGJ pressure (EGJP) and the integrated relaxation pressure (IRP), as indicators of treatment response in achalasia. METHODS: We prospectively evaluated 75 patients (ages 19-81, 32 female) with achalasia during follow-up after pneumatic dilation or myotomy with Eckardt score (ES), timed-barium esophagram (TBE), and HRIM. Receiver-operating characteristic (ROC) curves for good symptomatic outcome (ES<=3) and good radiographic outcome (TBE column height at 5 min<5 cm) were generated for each potential predictor of treatment response (EGJP, IRP, BFT, and EGJ-CI). RESULTS: Follow-up occurred at a median (range) 12 (3-291) months following treatment. A total of 49 patients had good symptomatic outcome and 46 had good radiographic outcome. The area-under-the-curves (AUCs) on the ROC curve for symptomatic outcome were 0.55 (EGJP), 0.62 (IRP), 0.77 (BFT) and 0.56 (EGJ-CI). The AUCs for radiographic outcome were 0.64 (EGJP), 0.48 (IRP), 0.73 (BFT), and 0.65 (EGJ-CI). Optimal cut-points were determined as 11 mm Hg (EGJP), 12 mm Hg (IRP), 0 s (BFT), and 30 mm Hg*cm (EGJ-CI) that provided sensitivities/specificities of 57%/46% (EGJP), 65%/58% (IRP), 78%/77% (BFT), and 53%/62% (EGJ-CI) to predict symptomatic outcome and 57%/66% (EGJP), 57%/41% (IRP), 76%/69% (BFT), and 57%/66% (EGJ-CI) to predict radiographic outcome. CONCLUSIONS: BFT, a novel HRIM metric, provided an improved functional assessment over manometric measures of EGJP, IRP, and EGJ-CI at follow-up after achalasia treatment and may help direct clinical management. PMID- 27698383 TI - Outer membrane vesicles from flagellin-deficient Salmonella enterica serovar Typhimurium induce cross-reactive immunity and provide cross-protection against heterologous Salmonella challenge. AB - Outer membrane vesicles (OMVs) isolated from Salmonella Typhimurium are potentially useful for developing subunit vaccines because of high immunogenicity and protective efficacy. However, flagella might remain in OMV pellets following OMV purification, resulting in non-essential immune responses and counteraction of bacterial protective immune responses when developing a vaccine against infection of multiple serotypes Salmonella. In this study, a flagellin-deficient S. Typhimurium mutant was constructed. Lipopolysaccharide profiles, protein profiles and cryo-electron microscopy revealed that there were no significant differences between the wild-type and mutant OMVs, with the exception of a large amount of flagellin in the wild-type OMVs. Neither the wild-type OMVs nor the non flagellin OMVs were toxic to macrophages. Mice immunized with the non-flagellin OMVs produced high concentrations of IgG. The non-flagellin OMVs elicited strong mucosal antibody responses in mice when administered via the intranasal route in addition to provoking higher cross-reactive immune responses against OMPs isolated from S. Choleraesuis and S. Enteritidis. Both intranasal and intraperitoneal immunization with the non-flagellin OMVs provided efficient protection against heterologous S. Choleraesuis and S. Enteritidis challenge. Our results indicate that the flagellin-deficient OMVs may represent a new vaccine platform that could be exploited to facilitate the production of a broadly protective vaccine. PMID- 27698387 TI - Negative Is Positive. PMID- 27698385 TI - Photodynamic N-TiO2 Nanoparticle Treatment Induces Controlled ROS-mediated Autophagy and Terminal Differentiation of Leukemia Cells. AB - In this study, we used nitrogen-doped titanium dioxide (N-TiO2) NPs in conjugation with visible light, and show that both reactive oxygen species (ROS) and autophagy are induced by this novel NP-based photodynamic therapy (PDT) system. While well-dispersed N-TiO2 NPs (<=100 MUg/ml) were inert, their photo activation with visible light led to ROS-mediated autophagy in leukemia K562 cells and normal peripheral lymphocytes, and this increased in parallel with increasing NP concentrations and light doses. At a constant light energy (12 J/cm2), increasing N-TiO2 NP concentrations increased ROS levels to trigger autophagy-dependent megakaryocytic terminal differentiation in K562 cells. By contrast, an ROS challenge induced by high N-TiO2 NP concentrations led to autophagy-associated apoptotic cell death. Using chemical autophagy inhibitors (3 methyladenine and Bafilomycin A1), we confirmed that autophagy is required for both terminal differentiation and apoptosis induced by photo-activated N-TiO2. Pre-incubation of leukemic cells with ROS scavengers muted the effect of N-TiO2 NP-based PDT on cell fate, highlighting the upstream role of ROS in our system. In summary, PDT using N-TiO2 NPs provides an effective method of priming autophagy by ROS induction. The capability of photo-activated N-TiO2 NPs in obtaining desirable cellular outcomes represents a novel therapeutic strategy of cancer cells. PMID- 27698388 TI - The variances of Sp1 and NF-kappaB elements correlate with the greater capacity of Chinese HIV-1 B'-LTR for driving gene expression. AB - The 5' end of HIV-1 long terminal repeat (LTR) serves as a promoter that plays an essential role in driving viral gene transcription. Manipulation of HIV-1 LTR provides a potential therapeutic strategy for suppressing viral gene expression or excising integrated provirus. Subtype-specific genetic diversity in the LTR region has been observed. The minor variance of LTR, particularly in the transcription factor binding sites, can have a profound impact on its activity. However, the LTR profiles from major endemic Chinese subtypes are not well characterized. Here, by characterizing the sequences and functions of LTRs from endemic Chinese HIV-1 subtypes, we showed that nucleotide variances of Sp1 core promoter and NF-kappaB element are associated with varied LTR capacity for driving viral gene transcription. The greater responsiveness of Chinese HIV-1 B' LTR for driving viral gene transcription upon stimulation is associated with an increased level of viral reactivation. Moreover, we demonstrated that the introduction of CRISPR/dead Cas9 targeting Sp1 or NF-kappaB element suppressed viral gene expression. Taken together, our study characterized LTRs from endemic HIV-1 subtypes in China and suggests a potential target for the suppression of viral gene expression and a novel strategy that facilitates the accomplishment of a functional cure. PMID- 27698389 TI - Aldo-keto reductase 1C1 induced by interleukin-1beta mediates the invasive potential and drug resistance of metastatic bladder cancer cells. AB - In treating bladder cancer, determining the molecular mechanisms of tumor invasion, metastasis, and drug resistance are urgent to improving long-term patient survival. One of the metabolic enzymes, aldo-keto reductase 1C1 (AKR1C1), plays an essential role in cancer invasion/metastasis and chemoresistance. In orthotopic xenograft models of a human bladder cancer cell line, UM-UC-3, metastatic sublines were established from tumors in the liver, lung, and bone. These cells possessed elevated levels of EMT-associated markers, such as Snail, Slug, or CD44, and exhibited enhanced invasion. By microarray analysis, AKR1C1 was found to be up-regulated in metastatic lesions, which was verified in metastatic human bladder cancer specimens. Decreased invasion caused by AKR1C1 knockdown suggests a novel role of AKR1C1 in cancer invasion, which is probably due to the regulation of Rac1, Src, or Akt. An inflammatory cytokine, interleukin 1beta, was found to increase AKR1C1 in bladder cancer cell lines. One particular non-steroidal anti-inflammatory drug, flufenamic acid, antagonized AKR1C1 and decreased the cisplatin-resistance and invasion potential of metastatic sublines. These data uncover the crucial role of AKR1C1 in regulating both metastasis and drug resistance; as a result, AKR1C1 should be a potent molecular target in invasive bladder cancer treatment. PMID- 27698390 TI - ProQ3: Improved model quality assessments using Rosetta energy terms. AB - Quality assessment of protein models using no other information than the structure of the model itself has been shown to be useful for structure prediction. Here, we introduce two novel methods, ProQRosFA and ProQRosCen, inspired by the state-of-art method ProQ2, but using a completely different description of a protein model. ProQ2 uses contacts and other features calculated from a model, while the new predictors are based on Rosetta energies: ProQRosFA uses the full-atom energy function that takes into account all atoms, while ProQRosCen uses the coarse-grained centroid energy function. The two new predictors also include residue conservation and terms corresponding to the agreement of a model with predicted secondary structure and surface area, as in ProQ2. We show that the performance of these predictors is on par with ProQ2 and significantly better than all other model quality assessment programs. Furthermore, we show that combining the input features from all three predictors, the resulting predictor ProQ3 performs better than any of the individual methods. ProQ3, ProQRosFA and ProQRosCen are freely available both as a webserver and stand-alone programs at http://proq3.bioinfo.se/. PMID- 27698391 TI - A crucial role for spatial distribution in bacterial quorum sensing. AB - Quorum sensing (QS) is a process that enables bacteria to communicate using secreted signaling molecules, and then makes a population of bacteria to regulate gene expression collectively and control behavior on a community-wide scale. Theoretical studies of efficiency sensing have suggested that both mass-transfer performance in the local environment and the spatial distribution of cells are key factors affecting QS. Here, an experimental model based on hydrogel microcapsules with a three-dimensional structure was established to investigate the influence of the spatial distribution of cells on bacterial QS. Vibrio harveyi cells formed different spatial distributions in the microcapsules, i.e., they formed cell aggregates with different structures and sizes. The cell aggregates displayed stronger QS than did unaggregated cells even when equal numbers of cells were present. Large aggregates (LA) of cells, with a size of approximately 25 MUm, restricted many more autoinducers (AIs) than did small aggregates (SA), with a size of approximately 10 MUm, thus demonstrating that aggregate size significantly affects QS. These findings provide a powerful demonstration of the fact that the spatial distribution of cells plays a crucial role in bacterial QS. PMID- 27698392 TI - Haptic adaptation to slant: No transfer between exploration modes. AB - Human touch is an inherently active sense: to estimate an object's shape humans often move their hand across its surface. This way the object is sampled both in a serial (sampling different parts of the object across time) and parallel fashion (sampling using different parts of the hand simultaneously). Both the serial (moving a single finger) and parallel (static contact with the entire hand) exploration modes provide reliable and similar global shape information, suggesting the possibility that this information is shared early in the sensory cortex. In contrast, we here show the opposite. Using an adaptation-and-transfer paradigm, a change in haptic perception was induced by slant-adaptation using either the serial or parallel exploration mode. A unified shape-based coding would predict that this would equally affect perception using other exploration modes. However, we found that adaptation-induced perceptual changes did not transfer between exploration modes. Instead, serial and parallel exploration components adapted simultaneously, but to different kinaesthetic aspects of exploration behaviour rather than object-shape per se. These results indicate that a potential combination of information from different exploration modes can only occur at down-stream cortical processing stages, at which adaptation is no longer effective. PMID- 27698393 TI - Tunable Surface Plasmon and Phonon Polariton Interactions for Moderately Doped Semiconductor Surfaces. AB - Spatial charge distribution for biased semiconductors fundamentally differs from metals since they can allow inhomogeneous charge distributions due to penetration of the electric field, as observed in the classical Schottky junctions. Similarly, the electrostatics of the dielectric/semiconductor interface can lead to a carrier depletion or accumulation in the semiconductor side when under applied bias. In this study, we demonstrate that the inhomogeneous carrier accumulation in a moderately p-doped GaAs-dielectric interface can be tailored for tunable plasmonics by an external voltage. Solving Maxwell's equations in the doped GaAs-dielectric stack, we investigate the tunability of the surface plasmon and phonon polaritons' interaction via an external bias. The plasmonic mode analysis of such an interface reveals interesting dispersion curves for surface plasmon and phonon polariton interactions that are not possible in metals. We show that the plasmon dispersion curve can be engineered through an external bias using the inherent properties of the p-doped GaAs- dielectric interface. PMID- 27698394 TI - The pioneering role of PRDM9 indel mutations in tarsier evolution. AB - PRDM9 is currently the sole speciation gene found in vertebrates causing hybrid sterility probably due to incompatible alleles. Its role in defining the double strand break loci during the meiotic prophase I is crucial for proper chromosome segregation. Therefore, the rapid turnover of the loci determining zinc finger array seems to be causative for incompatibilities. We here investigated the zinc finger domain-containing exon of PRDM9 in 23 tarsiers. Tarsiers, the most basal extant haplorhine primates, exhibit two frameshifting indels at the 5'-end of the array. The first mutation event interrupts the reading frame and function while the second compensates both. The fixation of this allele variant in tarsiers led to hypothesize that de- and reactivation of the zinc finger domain drove the speciation in early haplorhine or tarsiiform primates. Moreover, the high allelic diversity within Tarsius points to multiple effects of genetic drift reflecting their phylogeographic history since the Miocene.

PMID- 27698395 TI - Hierarchical phosphorylation of apical membrane antigen 1 is required for efficient red blood cell invasion by malaria parasites. AB - Central to the pathogenesis of malaria is the proliferation of Plasmodium falciparum parasites within human erythrocytes. Parasites invade erythrocytes via a coordinated sequence of receptor-ligand interactions between the parasite and host cell. One key ligand, Apical Membrane Antigen 1 (AMA1), is a leading blood stage vaccine and previous work indicates that phosphorylation of its cytoplasmic domain (CPD) is important to its function during invasion. Here we investigate the significance of each of the six available phospho-sites in the CPD. We confirm that the cyclic AMP/protein kinase A (PKA) signalling pathway elicits a phospho-priming step upon serine 610 (S610), which enables subsequent phosphorylation in vitro of a conserved, downstream threonine residue (T613) by glycogen synthase kinase 3 (GSK3). Both phosphorylation steps are required for AMA1 to function efficiently during invasion. This provides the first evidence that the functions of key invasion ligands of the malaria parasite are regulated by sequential phosphorylation steps. PMID- 27698396 TI - The ubiquitin ligase TRIM27 functions as a host restriction factor antagonized by Mycobacterium tuberculosis PtpA during mycobacterial infection. AB - Macrophage-mediated innate immune responses play crucial roles in host defense against pathogens. Recent years have seen an explosion of host proteins that act as restriction factors blocking viral replication in infected cells. However, the essential factors restricting Mycobacterium tuberculosis (Mtb) and their regulatory roles during mycobacterial infection remain largely unknown. We previously reported that Mtb tyrosine phosphatase PtpA, a secreted effector protein required for intracellular survival of Mtb, inhibits innate immunity by co-opting the host ubiquitin system. Here, we identified a new PtpA-interacting host protein TRIM27, which is reported to possess a conserved RING domain and usually acts as an E3 ubiquitin ligase that interferes with various cellular processes. We further demonstrated that TRIM27 restricts survival of mycobacteria in macrophages by promoting innate immune responses and cell apoptosis. Interestingly, Mtb PtpA could antagonize TRIM27-promoted JNK/p38 MAPK pathway activation and cell apoptosis through competitively binding to the RING domain of TRIM27. TRIM27 probably works as a potential restriction factor for Mtb and its function is counteracted by Mtb effector proteins such as PtpA. Our study suggests a potential tuberculosis treatment via targeting of the TRIM27-PtpA interfaces.

PMID- 27698400 TI - Evaluation of dusting versus basketing - can new technologies improve stone-free rates? AB - Over the past two decades, the management of upper-tract urinary stones has dramatically changed towards an increase in the use of ureteroscopic treatment. This change has been driven by technological advances such as the creation of flexible ureteroscopes with reduced calibre (which now have digital, disposable and dual flexion capability) and holmium lasers with increased power. Two basic principles exist when treating stones ureteroscopically: either creating stone dust and small fragments (<1-2 mm) to theoretically enable spontaneous passage of the small particles or stone fragmentation that enables safe extraction of the stone pieces with a basket or grasper in an efficient manner. Each method has unique advantages and disadvantages, but, ultimately, surgeon preference, stone size, composition, location and intrarenal and/or ureteral anatomy determine which technique is used. To date, clinical trials comparing these two techniques are lacking. PMID- 27698401 TI - Confirmation of an IRAK3 polymorphism as a genetic marker predicting response to anti-TNF treatment in rheumatoid arthritis. AB - Several genetic variants in Toll-like receptor (TLR) and nuclear factor (NF) kappaB signalling pathways have been reported associated with responsiveness to tumour necrosis factor inhibitor (anti-TNF) treatment in rheumatoid arthritis (RA). The present study was undertaken to replicate these findings. In a retrospective case-case study including 1007 Danish anti-TNF-treated RA patients, we genotyped 7 previously reported associated single-nucleotide polymorphisms (SNPs) in these pathways. Furthermore, 5 SNPs previously reported by our group were genotyped in a subcohort (N=469). Primary analyses validated the IRAK3 rs11541076 variant as associated (odds ratio (OR)=1.33, 95% confidence interval (CI): 1.00-1.77, P-value=0.047) with a positive treatment response (EULAR (European League Against Rheumatism) good/moderate vs none response at 4+/-2 months), and found the NLRP3 rs461266 variant associated (OR=0.75, 95% CI: 0.60 0.94, P=0.014) with a negative treatment response. Meta-analyses combining data from previous studies suggested smaller effect sizes of associations between variant alleles of CHUK rs11591741, NFKBIB rs3136645 and rs9403 and a negative treatment response. In conclusion, this study validates rs11541076 in IRAK3, a negative regulator of TLR signalling, as a predictor of anti-TNF treatment response, and suggests true positive associations of previously reported SNPs within genes encoding activators/inhibitors of NF-kappaB (CHUK, MYD88, NFKBIB, and NLRP3).

AB - The Hippo pathway is involved in colorectal cancer (CRC) development and progression. The Hippo regulator Rassf1a is also involved in the Ras signaling cascade. In this work, we tested single nucleotide polymorphisms within Hippo components and their association with outcome in CRC patients treated with cetuximab. Two cohorts treated with cetuximab plus chemotherapy were evaluated (198 RAS wild-type (WT) patients treated with first-line FOLFIRI plus Cetuximab within the FIRE-3 trial and 67 Ras WT patients treated either with first-line mFOLFOX6 or SOX plus Cetuximab). In these two populations, Rassf1a rs2236947 was associated with overall survival (OS), as patients with a CC genotype had significantly longer OS compared with those with CA or AA genotypes. This association was stronger in patients with left-side CRC (hazard ratio (HR): 1.79 (1.01-3.14); P=0.044 and HR: 2.83 (1.14-7.03); P=0.025, for Fire 3 and JACCRO cohorts, respectively). Rassf1a rs2236947 is a promising biomarker for patients treated with cetuximab plus chemotherapy. PMID- 27698404 TI - Neofunctionalization of zona pellucida proteins enhances freeze-prevention in the eggs of Antarctic notothenioids. AB - The mechanisms by which the eggs of the Antarctic notothenioid fishes avoid freezing are not fully understood. Zona pellucida proteins (ZPs) are constituents of the chorion which forms a protective matrix surrounding the egg. Here we report occurrence of freezing temperature-related gene expansion and acquisition of unusual ice melting-promoting (IMP) activity in a family of Antarctic notothenioid ZPs (AnnotoZPs). Members of AnnotoZPs are shown to bind with ice and non-colligatively depress the melting point of a solution in a range of 0.26 to 0.65 degrees C at a moderate concentration. Eggs of zebrafishes expressing an AnnotoZP transgene show improved melting point depression and enhanced survival in freezing conditions. Mutational analyses in a representative AnnotoZP indicate the ZP domain and patches of acidic residues are essential structures for the IMP activity. AnnotoZPs, therefore, represent a group of macromolecules that prevent freezing by a unique ZP-ice interaction mechanism distinct from the known antifreeze proteins. PMID- 27698405 TI - Structural insights into the assembly and regulation of distinct viral capsid complexes. AB - The assembly and regulation of viral capsid proteins into highly ordered macromolecular complexes is essential for viral replication. Here, we utilize crystal structures of the capsid protein from the smallest and simplest known viruses capable of autonomously replicating in animal cells, circoviruses, to establish structural and mechanistic insights into capsid morphogenesis and regulation. The beak and feather disease virus, like many circoviruses, encode only two genes: a capsid protein and a replication initiation protein. The capsid protein forms distinct macromolecular assemblies during replication and here we elucidate these structures at high resolution, showing that these complexes reverse the exposure of the N-terminal arginine rich domain responsible for DNA binding and nuclear localization. We show that assembly of these complexes is regulated by single-stranded DNA (ssDNA), and provide a structural basis of capsid assembly around single-stranded DNA, highlighting novel binding interfaces distinct from the highly positively charged N-terminal ARM domain. PMID- 27698407 TI - Relationship between neuroticism, childhood trauma and cognitive-affective responses to auditory verbal hallucinations. AB - Neuroticism has been shown to adversely influence the development and outcome of psychosis. However, how this personality trait associates with the individual's responses to psychotic symptoms is less well known. Auditory verbal hallucinations (AVHs) have been reported by patients with psychosis and non clinical individuals. There is evidence that voice-hearers who are more distressed by and resistant against the voices, as well as those who appraise the voices as malevolent and powerful, have poorer outcome. This study aimed to examine the mechanistic association of neuroticism with the cognitive-affective reactions to AVH. We assessed 40 psychotic patients experiencing frequent AVHs, 135 non-clinical participants experiencing frequent AVHs, and 126 healthy individuals. In both clinical and non-clinical voice-hearers alike, a higher level of neuroticism was associated with more distress and behavioral resistance in response to AVHs, as well as a stronger tendency to perceive voices as malevolent and powerful. Neuroticism fully mediated the found associations between childhood trauma and the individuals' cognitive-affective reactions to voices. Our results supported the role of neurotic personality in shaping maladaptive reactions to voices. Neuroticism may also serve as a putative mechanism linking childhood trauma and psychological reactions to voices. Implications for psychological models of hallucinations are discussed. PMID- 27698406 TI - Triggering signaling pathways using F-actin self-organization. AB - The spatiotemporal organization of proteins within cells is essential for cell fate behavior. Although it is known that the cytoskeleton is vital for numerous cellular functions, it remains unclear how cytoskeletal activity can shape and control signaling pathways in space and time throughout the cell cytoplasm. Here we show that F-actin self-organization can trigger signaling pathways by engineering two novel properties of the microfilament self-organization: (1) the confinement of signaling proteins and (2) their scaffolding along actin polymers. Using in vitro reconstitutions of cellular functions, we found that both the confinement of nanoparticle-based signaling platforms powered by F-actin contractility and the scaffolding of engineered signaling proteins along actin microfilaments can drive a signaling switch. Using Ran-dependent microtubule nucleation, we found that F-actin dynamics promotes the robust assembly of microtubules. Our in vitro assay is a first step towards the development of novel bottom-up strategies to decipher the interplay between cytoskeleton spatial organization and signaling pathway activity. PMID- 27698408 TI - Biodiversity of bacteriophages: morphological and biological properties of a large group of phages isolated from urban sewage. AB - A large scale analysis presented in this article focuses on biological and physiological variety of bacteriophages. A collection of 83 bacteriophages, isolated from urban sewage and able to propagate in cells of different bacterial hosts, has been obtained (60 infecting Escherichia coli, 10 infecting Pseudomonas aeruginosa, 4 infecting Salmonella enterica, 3 infecting Staphylococcus sciuri, and 6 infecting Enterococcus faecalis). High biological diversity of the collection is indicated by its characteristics, both morphological (electron microscopic analyses) and biological (host range, plaque size and morphology, growth at various temperatures, thermal inactivation, sensitivity to low and high pH, sensitivity to osmotic stress, survivability upon treatment with organic solvents and detergents), and further supported by hierarchical cluster analysis. By the end of the research no larger collection of phages from a single environmental source investigated by these means had been found. The finding was confirmed by whole genome analysis of 7 selected bacteriophages. Moreover, particular bacteriophages revealed unusual biological features, like the ability to form plaques at low temperature (4 degrees C), resist high temperature (62 degrees C or 95 degrees C) or survive in the presence of an organic solvents (ethanol, acetone, DMSO, chloroform) or detergent (SDS, CTAB, sarkosyl) making them potentially interesting in the context of biotechnological applications. PMID- 27698410 TI - Tuning Fullerene Intercalation in a Poly (thiophene) derivative by Controlling the Polymer Degree of Self-Organisation. AB - Controlling the nanoscale arrangement in polymer-fullerene organic solar cells is of paramount importance to boost the performance of such promising class of photovoltaic diodes. In this work, we use a pseudo-bilayer system made of poly(2,5-bis(3-hexadecylthiophen-2-yl)thieno[3,2-b]thiophene (PBTTT) and [6,6] phenyl-C61-butyric acid methyl ester (PCBM), to acquire a more complete understanding of the diffusion and intercalation of the fullerene-derivative within the polymer layer. By exploiting morphological and structural characterisation techniques, we observe that if we increase the film solidification time the polymer develops a higher crystalline order, and, as a result, it does not allow fullerene molecules to intercalate between the polymer side-chains. Gaining insight into the detailed fullerene intercalation mechanism is important for the development of organic photovoltaic diodes (PVDs). PMID- 27698409 TI - Increased nicotine response in iPSC-derived human neurons carrying the CHRNA5 N398 allele. AB - Genetic variation in nicotinic receptor alpha 5 (CHRNA5) has been associated with increased risk of addiction-associated phenotypes in humans yet little is known the underlying neural basis. Induced pluripotent stem cells (iPSCs) were derived from donors homozygous for either the major (D398) or the minor (N398) allele of the nonsynonymous single nucleotide polymorphism (SNP), rs16969968, in CHRNA5. To understand the impact of these nicotinic receptor variants in humans, we differentiated these iPSCs to dopamine (DA) or glutamatergic neurons and then tested their functional properties and response to nicotine. Results show that N398 variant human DA neurons differentially express genes associated with ligand receptor interaction and synaptic function. While both variants exhibited physiological properties consistent with mature neuronal function, the N398 neuronal population responded more actively with an increased excitatory postsynaptic current response upon the application of nicotine in both DA and glutamatergic neurons. Glutamatergic N398 neurons responded to lower nicotine doses (0.1 MUM) with greater frequency and amplitude but they also exhibited rapid desensitization, consistent with previous analyses of N398-associated nicotinic receptor function. This study offers a proof-of-principle for utilizing human neurons to study gene variants contribution to addiction. PMID- 27698411 TI - An expression based REST signature predicts patient survival and therapeutic response for glioblastoma multiforme. AB - Proper regulation of neuronal gene expression is crucial for the development and differentiation of the central nervous system. The transcriptional repressor REST (repressor element-1 silencing transcription factor) is a key regulator in differentiation of pluripotent stem cells to neuronal progenitors and mature neurons. Dysregulated REST activity has been implicated in various diseases, among which the most deadly is glioblastoma multiforme (GBM). Here we have developed an expression-based REST signature (EXPREST), a device providing quantitative measurements of REST activity for GBM tumors. EXPREST robustly quantifies REST activity (REST score) using gene expression profiles in absence of clinic-pathologic assessments of REST. Molecular characterization of REST activity identified global alterations at the DNA, RNA, protein and microRNA levels, suggesting a widespread role of REST in GBM tumorigenesis. Although originally aimed to capture REST activity, REST score was found to be a prognostic factor for overall survival. Further, cell lines with enhanced REST activity was found to be more sensitive to IGF1R, VEGFR and ABL inhibitors. In contrast, cell lines with low REST score were more sensitive to cytotoxic drugs including Mitomycin, Camptothecin and Cisplatin. Together, our work suggests that therapeutic targeting of REST provides a promising opportunity for GBM treatment. PMID- 27698412 TI - ALB3 Insertase Mediates Cytochrome b6 Co-translational Import into the Thylakoid Membrane. AB - The cytochrome b6 f complex occupies an electrochemically central position in the electron-transport chain bridging the photosynthetic reaction center of PS I and PS II. In plants, the subunits of these thylakoid membrane protein complexes are both chloroplast and nuclear encoded. How the chloroplast-encoded subunits of multi-spanning cytochrome b6 are targeted and inserted into the thylakoid membrane is not fully understood. Experimental approaches to evaluate the cytochrome b6 import mechanism in vivo have been limited to bacterial membranes and were not a part of the chloroplast environment. To evaluate the mechanism governing cytochrome b6 integration in vivo, we performed a comparative analysis of both native and synthetic cytochrome b6 insertion into purified thylakoids. Using biophysical and biochemical methods, we show that cytochrome b6 insertion into the thylakoid membrane is a non-spontaneous co-translational process that involves ALB3 insertase. Furthermore, we provided evidence that CSP41 (chloroplast stem-loop-binding protein of 41 kDa) interacts with RNC-cytochrome b6 complexes, and may be involved in cytochrome b6 (petB) transcript stabilization or processing. PMID- 27698413 TI - Lithium-ion-based solid electrolyte tuning of the carrier density in graphene. AB - We have developed a technique to tune the carrier density in graphene using a lithium-ion-based solid electrolyte. We demonstrate that the solid electrolyte can be used as both a substrate to support graphene and a back gate. It can induce a change in the carrier density as large as 1 * 1014 cm-2, which is much larger than that induced with oxide-film dielectrics, and it is comparable with that induced by liquid electrolytes. Gate modulation of the carrier density is still visible at 150 K, which is lower than the glass transition temperature of most liquid gating electrolytes. PMID- 27698414 TI - Scaffold Hopping Toward Agomelatine: Novel 3, 4-Dihydroisoquinoline Compounds as Potential Antidepressant Agents. AB - A scaffold-hopping strategy toward Agomelatine based on in silico screening and knowledge analysis was employed to design novel antidepressant agents. A series of 3, 4-dihydroisoquinoline compounds were selected for chemical synthesis and biological assessment. Three compounds (6a-1, 6a-2, 6a-9) demonstrated protective effects on corticosterone-induced lesion of PC12 cells. Compound 6a-1 also displayed low inhibitory effects on the growth of HEK293 and L02 normal cells and it was further evaluated for its potential antidepressant effects in vivo. The forced swim test (FST) results revealed that compound 6a-1 remarkably reduced the immobility time of rats and the open field test (OFT) results indicated a better general locomotor activity of the rats treated with compound 6a-1 than those with Agomelatine or Fluoxetine. Mechanism studies implied that compound 6a-1 can significantly reduce PC12 cell apoptosis by up-regulation of GSH and down regulation of ROS in corticosterone-induced lesion of PC12 cells. Meanwhile, the down-regulation of calcium ion concentration and up-regulation of BDNF level in PC12 cells may account for the neuroprotective effects. Furthermore, compound 6a 1 can increase cell survival and cell proliferation, promote cell maturation in the rat hippocampus after chronic treatment. The acute toxicity data in vivo indicated compound 6a-1 exhibited less hepatotoxicity than Agomelatine. PMID- 27698415 TI - Real-space investigation of energy transfer in heterogeneous molecular dimers. AB - Given its central role in photosynthesis and artificial energy-harvesting devices, energy transfer has been widely studied using optical spectroscopy to monitor excitation dynamics and probe the molecular-level control of energy transfer between coupled molecules. However, the spatial resolution of conventional optical spectroscopy is limited to a few hundred nanometres and thus cannot reveal the nanoscale spatial features associated with such processes. In contrast, scanning tunnelling luminescence spectroscopy has revealed the energy dynamics associated with phenomena ranging from single-molecule electroluminescence, absorption of localized plasmons and quantum interference effects to energy delocalization and intervalley electron scattering with submolecular spatial resolution in real space. Here we apply this technique to individual molecular dimers that comprise a magnesium phthalocyanine and a free base phthalocyanine (MgPc and H2Pc) and find that locally exciting MgPc with the tunnelling current of the scanning tunnelling microscope generates a luminescence signal from a nearby H2Pc molecule as a result of resonance energy transfer from the former to the latter. A reciprocating resonance energy transfer is observed when exciting the second singlet state (S2) of H2Pc, which results in energy transfer to the first singlet state (S1) of MgPc and final funnelling to the S1 state of H2Pc. We also show that tautomerization of H2Pc changes the energy transfer characteristics within the dimer system, which essentially makes H2Pc a single-molecule energy transfer valve device that manifests itself by blinking resonance energy transfer behaviour. PMID- 27698416 TI - Tissue-specific mutation accumulation in human adult stem cells during life. AB - The gradual accumulation of genetic mutations in human adult stem cells (ASCs) during life is associated with various age-related diseases, including cancer. Extreme variation in cancer risk across tissues was recently proposed to depend on the lifetime number of ASC divisions, owing to unavoidable random mutations that arise during DNA replication. However, the rates and patterns of mutations in normal ASCs remain unknown. Here we determine genome-wide mutation patterns in ASCs of the small intestine, colon and liver of human donors with ages ranging from 3 to 87 years by sequencing clonal organoid cultures derived from primary multipotent cells. Our results show that mutations accumulate steadily over time in all of the assessed tissue types, at a rate of approximately 40 novel mutations per year, despite the large variation in cancer incidence among these tissues. Liver ASCs, however, have different mutation spectra compared to those of the colon and small intestine. Mutational signature analysis reveals that this difference can be attributed to spontaneous deamination of methylated cytosine residues in the colon and small intestine, probably reflecting their high ASC division rate. In liver, a signature with an as-yet-unknown underlying mechanism is predominant. Mutation spectra of driver genes in cancer show high similarity to the tissue-specific ASC mutation spectra, suggesting that intrinsic mutational processes in ASCs can initiate tumorigenesis. Notably, the inter-individual variation in mutation rate and spectra are low, suggesting tissue-specific activity of common mutational processes throughout life. PMID- 27698417 TI - A cholinergic basal forebrain feeding circuit modulates appetite suppression. AB - Atypical food intake is a primary cause of obesity and other eating and metabolic disorders. Insight into the neural control of feeding has previously focused mainly on signalling mechanisms associated with the hypothalamus, the major centre in the brain that regulates body weight homeostasis. However, roles of non canonical central nervous system signalling mechanisms in regulating feeding behaviour have been largely uncharacterized. Acetylcholine has long been proposed to influence feeding owing in part to the functional similarity between acetylcholine and nicotine, a known appetite suppressant. Nicotine is an exogenous agonist for acetylcholine receptors, suggesting that endogenous cholinergic signalling may play a part in normal physiological regulation of feeding. However, it remains unclear how cholinergic neurons in the brain regulate food intake. Here we report that cholinergic neurons of the mouse basal forebrain potently influence food intake and body weight. Impairment of cholinergic signalling increases food intake and results in severe obesity, whereas enhanced cholinergic signalling decreases food consumption. We found that cholinergic circuits modulate appetite suppression on downstream targets in the hypothalamus. Together our data reveal the cholinergic basal forebrain as a major modulatory centre underlying feeding behaviour. PMID- 27698420 TI - Pore architecture of TRIC channels and insights into their gating mechanism. AB - Intracellular Ca2+ signalling processes are fundamental to muscle contraction, neurotransmitter release, cell growth and apoptosis. Release of Ca2+ from the intracellular stores is supported by a series of ion channels in sarcoplasmic or endoplasmic reticulum (SR/ER). Among them, two isoforms of the trimeric intracellular cation (TRIC) channel family, named TRIC-A and TRIC-B, modulate the release of Ca2+ through the ryanodine receptor or inositol triphosphate receptor, and maintain the homeostasis of ions within SR/ER lumen. Genetic ablations or mutations of TRIC channels are associated with hypertension, heart disease, respiratory defects and brittle bone disease. Despite the pivotal function of TRIC channels in Ca2+ signalling, their pore architectures and gating mechanisms remain unknown. Here we present the structures of TRIC-B1 and TRIC-B2 channels from Caenorhabditis elegans in complex with endogenous phosphatidylinositol-4,5 biphosphate (PtdIns(4,5)P2, also known as PIP2) lipid molecules. The TRIC-B1/B2 proteins and PIP2 assemble into a symmetrical homotrimeric complex. Each monomer contains an hourglass-shaped hydrophilic pore contained within a seven transmembrane-helix domain. Structural and functional analyses unravel the central role of PIP2 in stabilizing the cytoplasmic gate of the ion permeation pathway and reveal a marked Ca2+-induced conformational change in a cytoplasmic loop above the gate. A mechanistic model has been proposed to account for the complex gating mechanism of TRIC channels. PMID- 27698419 TI - X-ray structure of the human alpha4beta2 nicotinic receptor. AB - Nicotinic acetylcholine receptors are ligand-gated ion channels that mediate fast chemical neurotransmission at the neuromuscular junction and have diverse signalling roles in the central nervous system. The nicotinic receptor has been a model system for cell-surface receptors, and specifically for ligand-gated ion channels, for well over a century. In addition to the receptors' prominent roles in the development of the fields of pharmacology and neurobiology, nicotinic receptors are important therapeutic targets for neuromuscular disease, addiction, epilepsy and for neuromuscular blocking agents used during surgery. The overall architecture of the receptor was described in landmark studies of the nicotinic receptor isolated from the electric organ of Torpedo marmorata. Structures of a soluble ligand-binding domain have provided atomic-scale insights into receptor ligand interactions, while high-resolution structures of other members of the pentameric receptor superfamily provide touchstones for an emerging allosteric gating mechanism. All available high-resolution structures are of homopentameric receptors. However, the vast majority of pentameric receptors (called Cys-loop receptors in eukaryotes) present physiologically are heteromeric. Here we present the X-ray crystallographic structure of the human alpha4beta2 nicotinic receptor, the most abundant nicotinic subtype in the brain. This structure provides insights into the architectural principles governing ligand recognition, heteromer assembly, ion permeation and desensitization in this prototypical receptor class. PMID- 27698418 TI - Genomic insights into the peopling of the Southwest Pacific. AB - The appearance of people associated with the Lapita culture in the South Pacific around 3,000 years ago marked the beginning of the last major human dispersal to unpopulated lands. However, the relationship of these pioneers to the long established Papuan people of the New Guinea region is unclear. Here we present genome-wide ancient DNA data from three individuals from Vanuatu (about 3,100 2,700 years before present) and one from Tonga (about 2,700-2,300 years before present), and analyse them with data from 778 present-day East Asians and Oceanians. Today, indigenous people of the South Pacific harbour a mixture of ancestry from Papuans and a population of East Asian origin that no longer exists in unmixed form, but is a match to the ancient individuals. Most analyses have interpreted the minimum of twenty-five per cent Papuan ancestry in the region today as evidence that the first humans to reach Remote Oceania, including Polynesia, were derived from population mixtures near New Guinea, before their further expansion into Remote Oceania. However, our finding that the ancient individuals had little to no Papuan ancestry implies that later human population movements spread Papuan ancestry through the South Pacific after the first peopling of the islands. PMID- 27698422 TI - Cascaded plasmon-plasmon coupling mediated energy transfer across stratified metal-dielectric nanostructures. AB - Surface plasmon (SP) coupling has been successfully applied to nonradiative energy transfer via exciton-plasmon-exciton coupling in conventionally sandwiched donor-metal film-acceptor configurations. However, these structures lack the desired efficiency and suffer poor photoemission due to the high energy loss. Here, we show that the cascaded exciton-plasmon-plasmon-exciton coupling in stratified architecture enables an efficient energy transfer mechanism. The overlaps of the surface plasmon modes at the metal-dielectric and dielectric metal interfaces allow for strong cross-coupling in comparison with the single metal film configuration. The proposed architecture has been demonstrated through the analytical modeling and numerical simulation of an oscillating dipole near the stratified nanostructure of metal-dielectric-metal-acceptor. Consistent with theoretical and numerical results, experimental measurements confirm at least 50% plasmon resonance energy transfer enhancement in the donor-metal-dielectric-metal acceptor compared to the donor-metal-acceptor structure. Cascaded plasmon-plasmon coupling enables record high efficiency for exciton transfer through metallic structures. PMID- 27698421 TI - Effect of an Experimental Direct Pulp-capping Material on the Properties and Osteogenic Differentiation of Human Dental Pulp Stem Cells. AB - Effective pulp-capping materials must have antibacterial properties and induce dentin bridge formation; however, many current materials do not satisfy clinical requirements. Accordingly, the effects of an experiment pulp-capping material (Exp) composed of an antibacterial resin monomer (MAE-DB) and Portland cement (PC) on the viability, adhesion, migration, and differentiation of human dental pulp stem cells (hDPSCs) were examined. Based on a Cell Counting Kit-8 assay, hDPSCs exposed to Exp extracts showed limited viability at 24 and 48 h, but displayed comparable viability to the control at 72 h. hDPSC treatment with Exp extracts enhanced cellular adhesion and migration according to in vitro scratch wound healing and Transwell migration assays. Exp significantly upregulated the expression of osteogenesis-related genes. The hDPSCs cultured with Exp exhibited higher ALP activity and calcium deposition in vitro compared with the control group. The novel material showed comparable cytocompatibility to control cells and promoted the adhesion, migration, and osteogenic differentiation of hDPSCs, indicating excellent biocompatibility. This new direct pulp-capping material containing MAE-DB and PC shows promise as a potential alternative to conventional materials for direct pulp capping. PMID- 27698424 TI - Structure of the Neisseria meningitidis Type IV pilus. AB - Neisseria meningitidis use Type IV pili (T4P) to adhere to endothelial cells and breach the blood brain barrier, causing cause fatal meningitis. T4P are multifunctional polymers of the major pilin protein, which share a conserved hydrophobic N terminus that is a curved extended alpha-helix, alpha1, in X-ray crystal structures. Here we report a 1.44 A crystal structure of the N. meningitidis major pilin PilE and a ~6 A cryo-electron microscopy reconstruction of the intact pilus, from which we built an atomic model for the filament. This structure reveals the molecular arrangement of the N-terminal alpha-helices in the filament core, including a melted central portion of alpha1 and a bridge of electron density consistent with a predicted salt bridge necessary for pilus assembly. This structure has important implications for understanding pilus biology. PMID- 27698423 TI - Deubiquitinase activity is required for the proteasomal degradation of misfolded cytosolic proteins upon heat-stress. AB - Elimination of misfolded proteins is crucial for proteostasis and to prevent proteinopathies. Nedd4/Rsp5 emerged as a major E3-ligase involved in multiple quality control pathways that target misfolded plasma membrane proteins, aggregated polypeptides and cytosolic heat-induced misfolded proteins for degradation. It remained unclear how in one case cytosolic heat-induced Rsp5 substrates are destined for proteasomal degradation, whereas other Rsp5 quality control substrates are otherwise directed to lysosomal degradation. Here we find that Ubp2 and Ubp3 deubiquitinases are required for the proteasomal degradation of cytosolic misfolded proteins targeted by Rsp5 after heat-shock (HS). The two deubiquitinases associate more with Rsp5 upon heat-stress to prevent the assembly of K63-linked ubiquitin on Rsp5 heat-induced substrates. This activity was required to promote the K48-mediated proteasomal degradation of Rsp5 HS-induced substrates. Our results indicate that ubiquitin chain editing is key to the cytosolic protein quality control under stress conditions. PMID- 27698426 TI - Magnetodielectric detection of magnetic quadrupole order in Ba(TiO)Cu4(PO4)4 with Cu4O12 square cupolas. AB - In vortex-like spin arrangements, multiple spins can combine into emergent multipole moments. Such multipole moments have broken space-inversion and time reversal symmetries, and can therefore exhibit linear magnetoelectric (ME) activity. Three types of such multipole moments are known: toroidal; monopole; and quadrupole moments. So far, however, the ME activity of these multipole moments has only been established experimentally for the toroidal moment. Here we propose a magnetic square cupola cluster, in which four corner-sharing square coordinated metal-ligand fragments form a noncoplanar buckled structure, as a promising structural unit that carries an ME-active multipole moment. We substantiate this idea by observing clear magnetodielectric signals associated with an antiferroic ME-active magnetic quadrupole order in the real material Ba(TiO)Cu4(PO4)4. The present result serves as a useful guide for exploring and designing new ME-active materials based on vortex-like spin arrangements. PMID- 27698425 TI - Novel near-infrared emission from crystal defects in MoS2 multilayer flakes. AB - The structural defects in two-dimensional transition metal dichalcogenides, including point defects, dislocations and grain boundaries, are scarcely considered regarding their potential to manipulate the electrical and optical properties of this class of materials, notwithstanding the significant advances already made. Indeed, impurities and vacancies may influence the exciton population, create disorder-induced localization, as well as modify the electrical behaviour of the material. Here we report on the experimental evidence, confirmed by ab initio calculations, that sulfur vacancies give rise to a novel near-infrared emission peak around 0.75 eV in exfoliated MoS2 flakes. In addition, we demonstrate an excess of sulfur vacancies at the flake's edges by means of cathodoluminescence mapping, aberration-corrected transmission electron microscopy imaging and electron energy loss analyses. Moreover, we show that ripplocations, extended line defects peculiar to this material, broaden and redshift the MoS2 indirect bandgap emission. PMID- 27698427 TI - Cannabinoid CB1 receptors in distinct circuits of the extended amygdala determine fear responsiveness to unpredictable threat. AB - The brain circuits underlying behavioral fear have been extensively studied over the last decades. Although the vast majority of experimental studies assess fear as a transient state of apprehension in response to a discrete threat, such phasic states of fear can shift to a sustained anxious apprehension, particularly in face of diffuse cues with unpredictable environmental contingencies. Unpredictability, in turn, is considered an important variable contributing to anxiety disorders. The networks of the extended amygdala have been suggested keys to the control of phasic and sustained states of fear, although the underlying synaptic pathways and mechanisms remain poorly understood. Here, we show that the endocannabinoid system acting in synaptic circuits of the extended amygdala can explain the fear response profile during exposure to unpredictable threat. Using fear training with predictable or unpredictable cues in mice, combined with local and cell-type-specific deficiency and rescue of cannabinoid type 1 (CB1) receptors, we found that presynaptic CB1 receptors on distinct amygdala projections to bed nucleus of the stria terminalis (BNST) are both necessary and sufficient for the shift from phasic to sustained fear in response to an unpredictable threat. These results thereby identify the causal role of a defined protein in a distinct brain pathway for the temporal development of a sustained state of anxious apprehension during unpredictability of environmental influences, reminiscent of anxiety symptoms in humans. PMID- 27698428 TI - Predicting the functional states of human iPSC-derived neurons with single-cell RNA-seq and electrophysiology. AB - Human neural progenitors derived from pluripotent stem cells develop into electrophysiologically active neurons at heterogeneous rates, which can confound disease-relevant discoveries in neurology and psychiatry. By combining patch clamping, morphological and transcriptome analysis on single-human neurons in vitro, we defined a continuum of poor to highly functional electrophysiological states of differentiated neurons. The strong correlations between action potentials, synaptic activity, dendritic complexity and gene expression highlight the importance of methods for isolating functionally comparable neurons for in vitro investigations of brain disorders. Although whole-cell electrophysiology is the gold standard for functional evaluation, it often lacks the scalability required for disease modeling studies. Here, we demonstrate a multimodal machine learning strategy to identify new molecular features that predict the physiological states of single neurons, independently of the time spent in vitro. As further proof of concept, we selected one of the potential neurophysiological biomarkers identified in this study-GDAP1L1-to isolate highly functional live human neurons in vitro. PMID- 27698429 TI - Caspr2-reactive antibody cloned from a mother of an ASD child mediates an ASD like phenotype in mice. AB - Autism spectrum disorder (ASD) occurs in 1 in 68 births, preferentially affecting males. It encompasses a group of neurodevelopmental abnormalities characterized by impaired social interaction and communication, stereotypic behaviors and motor dysfunction. Although recent advances implicate maternal brain-reactive antibodies in a causative role in ASD, a definitive assessment of their pathogenic potential requires cloning of such antibodies. Here, we describe the isolation and characterization of monoclonal brain-reactive antibodies from blood of women with brain-reactive serology and a child with ASD. We further demonstrate that male but not female mice exposed in utero to the C6 monoclonal antibody, binding to contactin-associated protein-like 2 (Caspr2), display abnormal cortical development, decreased dendritic complexity of excitatory neurons and reduced numbers of inhibitory neurons in the hippocampus, as well as impairments in sociability, flexible learning and repetitive behavior. Anti Caspr2 antibodies are frequent in women with brain-reactive serology and a child with ASD. Together these studies provide a methodology for obtaining monclonal brain-reactive antibodies from blood B cells, demonstrate that ASD can result from in utero exposure to maternal brain-reactive antibodies of single specificity and point toward the exciting possibility of prognostic and protective strategies. PMID- 27698431 TI - Insulin resistance-a missing link no more. PMID- 27698430 TI - Hippocampal bone morphogenetic protein signaling mediates behavioral effects of antidepressant treatment. AB - Many antidepressants stimulate adult hippocampal neurogenesis, but the mechanisms by which they increase neurogenesis and modulate behavior are incompletely understood. Here we show that hippocampal bone morphogenetic protein (BMP) signaling is modulated by antidepressant treatment, and that the changes in BMP signaling mediate effects of antidepressant treatment on neural progenitor cell proliferation and behavior. Treatment with the selective serotonin reuptake inhibitor fluoxetine suppressed BMP signaling in the adult mouse hippocampus both by decreasing levels of BMP4 ligand and increasing production of the BMP inhibitor noggin. Increasing BMP signaling in the hippocampus via viral overexpression of BMP4 blocked the effects of fluoxetine on proliferation in the dentate gyrus and on depressive behavior. Conversely, inhibiting BMP signaling via viral overexpression of noggin in the hippocampus or infusion of noggin into the ventricles exerted antidepressant and anxiolytic activity along with an increase in hippocampal neurogenesis. Similarly, conditional genetic deletion of the type II BMP receptor in Ascl1-expressing cells promoted neurogenesis and reduced anxiety- and depression-like behaviors, suggesting that neural progenitor cells contribute to the effects of BMP signaling on affective behavior. These observations indicate that BMP signaling in the hippocampus regulates depressive behavior, and that decreasing BMP signaling may be required for the effects of some antidepressants. Thus BMP signaling is a new and powerful potential target for the treatment of depression.

PMID- 27698434 TI - In vivo imaging of brain microglial activity in antipsychotic-free and medicated schizophrenia: a [11C](R)-PK11195 positron emission tomography study. AB - Positron emission tomography (PET) imaging of the 18 kDa translocator protein (TSPO) has been used to investigate whether microglial activation, an indication of neuroinflammation, is evident in the brain of adults with schizophrenia. Interpretation of these studies is confounded by potential modulatory effects of antipsychotic medication on microglial activity. In the first such study in antipsychotic-free schizophrenia, we have used [11C](R)-PK11195 PET to compare TSPO availability in a predominantly antipsychotic-naive group of moderate-to severely symptomatic unmedicated patients (n=8), similarly symptomatic medicated patients with schizophrenia taking risperidone or paliperidone by regular intramuscular injection (n=8), and healthy comparison subjects (n=16). We found no evidence for increased TSPO availability in antipsychotic-free patients compared with healthy controls (mean difference 4%, P=0.981). However, TSPO availability was significantly elevated in medicated patients (mean increase 88%, P=0.032) across prefrontal (dorsolateral, ventrolateral, orbital), anterior cingulate and parietal cortical regions. In the patients, TSPO availability was also strongly correlated with negative symptoms measured using the Positive and Negative Syndrome Scale across all the brain regions investigated (r=0.651 0.741). We conclude that the pathophysiology of schizophrenia is not associated with microglial activation in the 2-6 year period following diagnosis. The elevation in the medicated patients may be a direct effect of the antipsychotic, although this study cannot exclude treatment resistance and/or longer illness duration as potential explanations. It also remains to be determined whether it is present only in a subset of patients, represents a pro- or anti-inflammatory state, its association with primary negative symptoms, and whether there are significant differences between antipsychotics.

AB - Synchronization of biological rhythms to the 24-hour day/night has long been studied with model organisms, under artificial light/dark cycles in the laboratory. The commonly used rectangular light/dark cycles, comprising hours of continuous light and darkness, may not be representative of the natural light exposure for most species, including humans. Subterranean rodents live in dark underground tunnels and offer a unique opportunity to investigate extreme mechanisms of photic entrainment in the wild. Here, we show automated field recordings of the daily light exposure patterns in a South American subterranean rodent, the tuco-tuco (Ctenomys aff. knighti ). In the laboratory, we exposed tuco-tucos to a simplified version of this natural light exposure pattern, to determine the minimum light timing information that is necessary for synchronization. As predicted from our previous studies using mathematical modeling, the activity rhythm of tuco-tucos synchronized to this mostly simplified light/dark regimen consisting of a single light pulse per day, occurring at randomly scattered times within a day length interval. Our integrated semi-natural, lab and computer simulation findings indicate that photic entrainment of circadian oscillators is robust, even in face of artificially reduced exposure and increased phase instability of the synchronizing stimuli.

AB - Anti-CD20 monoclonal antibodies (mAbs) represent an effective treatment for a number of B cell malignancies and autoimmune disorders. Glycoengineering of anti CD20mAb may contribute to increased anti-tumor efficacy through enhanced antibody dependent cellular cytotoxicity (ADCC) and phagocytosis (ADP) as reported by in vitro studies. However, where and how glycoengineered Ab may potentiate therapeutic responses in vivo is yet to be elucidated. Here, we have performed mouse liver transplants to demonstrate that the liver is sufficient to mediate systemic B cells depletion after anti-CD20 treatment. Relying on intravital two photon imaging of human CD20-expressing mice, we provide evidence that ADP by Kupffer cells (KC) is a major mechanism for rituximab-mediated B cell depletion. Notably, a glycoengineered anti-mouse CD20 Ab but not its wild-type counterpart triggered potent KC-mediated B cell depletion at low doses. Finally, distinct thresholds for KC phagocytosis were also observed for GA101 (obinutuzumab), a humanized glycoengineered type II anti-CD20 Ab and rituximab. Thus, we propose that enhanced phagocytosis of circulating B cells by KC represents an important in vivo mechanism underlying the improved activity of glycoengineered anti-CD20 mAbs.

AB - Pheromone-binding proteins (PBPs) are essential for the filtering, binding and transporting of sex pheromones across sensillum lymph to membrane-associated pheromone receptors of moths. In this study, three novel PBP genes were expressed in Escherichia coli to examine their involvement in the sex pheromone perception of Maruca vitrata. Fluorescence binding experiments indicated that MvitPBP1-3 had strong binding affinities with four sex pheromones. Moreover, molecular docking results demonstrated that six amino acid residues of three MvitPBPs were involved in the binding of the sex pheromones. These results suggested that MvitPBP1-3 might play critical roles in the perception of female sex pheromones. Additionally, the binding capacity of MvitPBP3 with the host-plant floral volatiles was high and was similar to that of MvitGOBP2. Furthermore, sequence alignment and docking analysis showed that both MvitGOBP2 and MvitPBP3 possessed an identical key binding site (arginine, R130/R140) and a similar protein pocket structure around the binding cavity. Therefore, we hypothesized that MvitPBP3 and MvitGOBP2 might have synergistic roles in binding different volatile ligands. In combination, the use of synthetic sex pheromones and floral volatiles from host plant may be used in the exploration for more efficient monitoring and integrated management strategies for the legume pod borer in the field.

AB - The genome sizes of five Miscanthus species, including 79 accessions of M. lutarioriparius, 8 of M. floridulus, 6 of M. sacchariflorus, 7 of M. sinensis, and 4 of M. * giganteus were examined using flow cytometry. The overall average nuclear DNA content were 4.256 +/- 0.6 pg/2C in M. lutarioriparius, 5.175 +/- 0.3 pg/2C in M. floridulus, 3.956 +/- 0.2 pg/2C in M. sacchariflorus, 5.272 +/- 0.2 pg/2C in M. sinensis, and 6.932 +/- 0.1 pg/2C in M. * giganteus. Interspecific variation was found at the diploid level, suggesting that DNA content might be a parameter that can be used to differentiate the species. Tetraploid populations were found in M. lutarioriparius, M. sacchariflorus, and M. sinensis, and their DNA content were 8.34 +/- 1.2, 8.52, and 8.355 pg, respectively. The association between the DNA content of M. lutarioriparius, collected from representative ranges across the Yangtze River, and its geographic distribution was statistically analyzed. A consistent pattern of DNA content variation in 79 M. lutarioriparius accessions across its entire geographic range was found in this study. Along the Yangtze River, the DNA content of M. lutarioriparius tended to increase from the upstream to the downstream areas, and almost all tetraploids gathered in the upstream area extended to coastal regions. PMID- 27698439 TI - Obesity and prostate cancer-specific mortality after radical prostatectomy: results from the Shared Equal Access Regional Cancer Hospital (SEARCH) database. AB - BACKGROUND: At the population level, obesity is associated with prostate cancer (PC) mortality. However, few studies analyzed the associations between obesity and long-term PC-specific outcomes after initial treatment. METHODS: We conducted a retrospective analysis of 4268 radical prostatectomy patients within the Shared Equal Access Regional Cancer Hospital (SEARCH) database. Cox models accounting for known risk factors were used to examine the associations between body mass index (BMI) and PC-specific mortality (PCSM; primary outcome). Secondary outcomes included biochemical recurrence (BCR) and castration-resistant PC (CRPC). BMI was used as a continuous and categorical variable (normal <25 kg/m2, overweight 25 29.9 kg/m2 and obese ?30 kg/m2). Median follow-up among all men who were alive at last follow-up was 6.8 years (interquartile range=3.5-11.0). During this time, 1384 men developed BCR, 117 developed CRPC and 84 died from PC. Hazard ratios were analyzed using competing-risks regression analysis accounting for non-PC death as a competing risk. RESULTS: On crude analysis, higher BMI was not associated with risk of PCSM (P=0.112), BCR (0.259) and CRPC (P=0.277). However, when BMI was categorized, overweight (hazard ratio (HR) 1.99, P=0.034) and obesity (HR 1.97, P=0.048) were significantly associated with PCSM. Obesity and overweight were not associated with BCR or CRPC (all P?0.189). On multivariable analysis adjusting for both clinical and pathological features, results were little changed in that obesity (HR=2.05, P=0.039) and overweight (HR=1.88, P=0.061) were associated with higher risk of PCSM, but not with BCR or CRPC (all P?0.114) with the exception that the association for overweight was no longer statistical significant. CONCLUSIONS: Overweight and obesity were associated with increased risk of PCSM after radical prostatectomy. If validated in larger studies with longer follow-up, obesity may be established as a potentially modifiable risk factor for PCSM. PMID- 27698440 TI - Long-term oncological outcomes of apical positive surgical margins at radical prostatectomy in the Shared Equal Access Regional Cancer Hospital cohort. AB - BACKGROUND: Approximately 29-38% of all positive surgical margins (PSMs) at radical prostatectomy (RP) involve the apex. The prognostic significance of apical PSM remains unclear. We therefore compared the long-term oncologic outcomes of men with apical PSMs to those with negative PSMs, apical and other PSMs, and other PSMs at RP. METHODS: The SEARCH (Shared Equal Access Regional Cancer Hospital) database was used to identify 4031 men with prostate cancer (PCa) managed with RP with complete pathologic grade and stage data. Margin status was categorized as negative, apex only, or other positive. Multivariable Cox regression models adjusted for pathologic stage and grade were developed to test the relationship between margin status and biochemical recurrence (BCR), metastases and PCa death. RESULTS: In the final cohort, 34.3% had PSMs, whereas 65.7% had negative margins. Univariable analysis showed that compared with negative margins, apex-only PSM was associated with BCR (hazard ratio (HR): 1.4 [1.1-1.8]), but not metastases or PCa death, whereas apex and other PSMs were associated with BCR (HR: 3.3 [2.8-4]) and metastases (HR: 1.8 [1.02-3.1]) but not PCa death. Nonapical PSMs were associated with BCR (HR: 2.7 [2.4-3.1]), metastases (1.7 [1.2-2.5)] and PCa death (1.8 [1.05-3]). On multivariable analysis, apex-only, apex and other, and nonapical PSMs were associated with BCR but margin status was not associated with metastases or PCa death. CONCLUSIONS: In a large cohort of men undergoing RP, those with PSMs at the prostatic apex had lower BCR, metastases, or PCa death compared with those with PSMs at other locations. When adjusted for pathologic stage and grade, however, PSMs were associated with BCR but not long-term oncologic outcomes. These data confirm that men with apex-only PSMs may not be ideal candidates for adjuvant therapy after RP. PMID- 27698441 TI - Formal nomenclature and description of cryptic species of the Encyrtus sasakii complex (Hymenoptera: Encyrtidae). AB - With the recent development of molecular approaches to species delimitation, a growing number of cryptic species have been discovered in what had previously been thought to be single morpho-species. Molecular methods, such as DNA barcoding, have greatly enhanced our knowledge of taxonomy, but taxonomy remains incomplete and needs a formal species nomenclature and description to facilitate its use in other scientific fields. A previous study using DNA barcoding, geometric morphometrics and mating tests revealed at least two cryptic species in the Encyrtus sasakii complex. (Hymenoptera: Encyrtidae). To describe these two new species formally (Encyrtus eulecaniumiae sp. nov. and Encyrtus rhodococcusiae sp. nov.), a detailed morphometric study of Encyrtus spp. was performed in addition to the molecular analysis and evaluation of biological data. Morphometric analyses, a multivariate ratio analysis (MRA) and a geometric morphometric analysis (GMA) revealed a great number of differences between the species, but reliable characteristics were not observed for diagnosing the cryptic species. We thus diagnosed these three Encyrtus species on the basis of the characteristics that resulted from genetic markers (mitochondrial cytochrome c oxidase subunit I and nuclear 28S rRNA) and biological data. A formal nomenclature and description of cryptic species was provided on the basis of an integrated taxonomy. PMID- 27698443 TI - Microwave birefringent metamaterials for polarization conversion based on spoof surface plasmon polariton modes. AB - We propose the design of wideband birefringent metamaterials based on spoof surface plasmon polaritons (SSPPs). Spatial k-dispersion design of SSPP modes in metamaterials is adopted to achieve high-efficiency transmission of electromagnetic waves through the metamaterial layer. By anisotropic design, the transmission phase accumulation in metamaterials can be independently modulated for x- and y-polarized components of incident waves. Since the dispersion curve of SSPPs is nonlinear, frequency-dependent phase differences can be obtained between the two orthogonal components of transmitted waves. As an example, we demonstrate a microwave birefringent metamaterials composed of fishbone structures. The full-polarization-state conversions on the zero-longitude line of Poincare sphere can be fulfilled twice in 6-20 GHz for both linearly polarized (LP) and circularly polarized (CP) waves incidence. Besides, at a given frequency, the full-polarization-state conversion can be achieved by changing the polarization angle of the incident LP waves. Both the simulation and experiment results verify the high-efficiency polarization conversion functions of the birefringent metamaterial, including circular-to-circular, circular-to linear(linear-to-circular), linear-to-linear polarization conversions. PMID- 27698442 TI - Up-regulation of miR-95-3p in hepatocellular carcinoma promotes tumorigenesis by targeting p21 expression. AB - Hepatocellular carcinoma (HCC) is one of the most common malignant cancers. To elucidate new regulatory mechanisms for heptocarcinogenesis, we investigated the regulation of p21, a cyclin-dependent kinase (CDK) inhibitor encoded by CDKN1A, in HCC. The expression level of p21 is decreased with the progression of HCC. Luciferase assays with a luciferase-p21-3' UTR reporter and its serial deletions identified a 15-bp repressor element at the 3'-UTR of CDKN1A, which contains a binding site for miR-95-3p. Mutation of the binding site eliminated the regulatory effect of miR-95-3p on p21 expression. Posttranscriptional regulation of p21 expression by miR-95-3p is mainly on the protein level (suppression of translation). Overexpression of miR-95-3p in two different HCC cell lines, HepG2 and SMMC7721, significantly promoted cell proliferation, cell cycle progression and cell migration, whereas a miR-95-3p specific inhibitor decreased cell proliferation, cell cycle progression and cell migration. The effects of miR-95 3p on cellular functions were rescued by overexpression of p21. Overexpression of miR-95-3p promoted cell proliferation and tumor growth in HCC xenograft mouse models. Expression of miR-95-3p was significantly higher in HCC samples than in adjacent non-cancerous samples. These results demonstrate that miR-95-3p is a potential new marker for HCC and regulates hepatocarcinogenesis by directly targeting CDKN1A/p21 expression.

PMID- 27698444 TI - Structure and specificity of the Type VI secretion system ClpV-TssC interaction in enteroaggregative Escherichia coli. AB - The Type VI secretion system (T6SS) is a versatile machine that delivers toxins into either eukaryotic or bacterial cells. It thus represents a key player in bacterial pathogenesis and inter-bacterial competition. Schematically, the T6SS can be viewed as a contractile tail structure anchored to the cell envelope. The contraction of the tail sheath propels the inner tube loaded with effectors towards the target cell. The components of the contracted tail sheath are then recycled by the ClpV AAA+ ATPase for a new cycle of tail elongation. The T6SS is widespread in Gram-negative bacteria and most of their genomes carry several copies of T6SS gene clusters, which might be activated in different conditions. Here, we show that the ClpV ATPases encoded within the two T6SS gene clusters of enteroaggregative Escherichia coli are not interchangeable and specifically participate to the activity of their cognate T6SS. Here we show that this specificity is dictated by interaction between the ClpV N-terminal domains and the N-terminal helices of their cognate TssC1 proteins. We also present the crystal structure of the ClpV1 N-terminal domain, alone or in complex with the TssC1 N-terminal peptide, highlighting the commonalities and diversities in the recruitment of ClpV to contracted sheaths. PMID- 27698447 TI - Long-term outcome of 6-month maintenance chemotherapy for acute lymphoblastic leukemia in children. AB - In the treatment of childhood acute lymphoblastic leukemia (ALL), excess shortening of maintenance therapy resulted in high relapse rate, as shown by our previous trial, TCCSG L92-13, in which maintenance therapy was terminated at 1 year from initiation of treatment. In this study, we aimed to confirm the long term outcome of L92-13, and to identify who can or cannot be cured by shorter duration of maintenance therapy. To obtain sentinel cytogenetics information that had been missed before, we performed genetic analysis with genomic microarray and target intron-capture sequencing from diagnostic bone marrow smear. Disease-free survival (DFS) at 10 years from the end of therapy was 66.0+/-2.8%. Females (n=138) had better DFS (74.6+/-3.7%) than males (n=142, 57.5+/-4.2%, P=0.002). Patients with TCF3-PBX1 (n=11) and ETV6-RUNX1 (n=16) had excellent DFS (90.9+/ 8.7% and 93.8+/-6.1%, respectively), whereas high hyperdiploidy (n=23) was the most unfavorable subgroup, with 56.6+/-10.3% of DFS. Short duration of therapy can cure more than half of pediatric ALL, especially females, TCF3-PBX1 and ETV6 RUNX1. Our retrospective observations suggest a gender/karyotype inhomogeneity on the impact of brief therapy.

AB - Microporous carbon compartments (MCCs) were developed via controlled carbonization of wheat flour producing large cavities that allow CO2 gas molecules to access micropores and adsorb effectively. KOH activation of MCCs was conducted at 700 degrees C with varying mass ratios of KOH/C ranging from 1 to 5, and the effects of activation conditions on the prepared carbon materials in terms of the characteristics and behavior of CO2 adsorption were investigated. Textural properties, such as specific surface area and total pore volume, linearly increased with the KOH/C ratio, attributed to the development of pores and enlargement of pores within carbon. The highest CO2 adsorption capacities of 5.70 mol kg-1 at 0 degrees C and 3.48 mol kg-1 at 25 degrees C were obtained for MCC activated with a KOH/C ratio of 3 (MCC-K3). In addition, CO2 adsorption uptake was significantly dependent on the volume of narrow micropores with a pore size of less than 0.8 nm rather than the volume of larger pores or surface area. MCC-K3 also exhibited excellent cyclic stability, facile regeneration, and rapid adsorption kinetics. As compared to the pseudo-first-order model, the pseudo second-order kinetic model described the experimental adsorption data methodically.

AB - Hexavalent Chromium [Cr(VI)], which can be found of various uses in industries such as metallurgy and textile dying, can cause a number of human disease including inflammation and cancer. Unlike previous research that focused on Cr(VI)-induced oxidative damage and apoptosis, this study placed emphasis on premature senescence that can be induced by low-dose and long-term Cr(VI) exposure. We found Cr(VI) induced premature senescence in L-02 hepatocytes, as confirmed by increase in senescence associated-beta-galactosidase (SA-beta-Gal) activity. Cr(VI) stabilized p53 through phosphorylation at Ser15 and increased expression of p53-transcriptional target p21. Mechanism study revealed Cr(VI) targeted and inhibited mitochondrial respiratory chain complex (MRCC) I and II to enhance reactive oxygen species (ROS) production. By applying antioxidant Trolox, we also confirmed that ROS mediated p53 activation. A tetracycline-inducible lentiviral expression system containing shRNA to p53 was used to knockout p53. We found p53 could inhibit pro-survival genes B-cell lymphoma-2 (Bcl-2), myeloid leukemia-1 (Mcl-1) and S phase related cell cycle proteins cyclin-dependent kinase 2 (CDK2), Cyclin E to induce premature senescence, and the functional role of ROS in Cr(VI)-induced premature senescence is depend on p53. The results suggest that Cr(VI) has a role in premature senescence by promoting ROS-dependent p53 activation in L-02 hepatocytes. PMID- 27698450 TI - 1,25 (OH)2D3 treatment alters the granulomatous response in M. tuberculosis infected mice. AB - Induction of cathelicidin-mediated antimicrobial pathway against intracellular M. tuberculosis by 1,25-dihydroxyvitamin D3 (1,25(OH)2D3), the active form of vitamin D, has been documented in vitro. However, in in vivo studies related to inflammatory disorders, 1,25(OH)2D3 has been demonstrated to induce an anti inflammatory response. We therefore examined whether in the murine model of tuberculosis, the anti-inflammatory effects of 1,25(OH)2D3 would affect the outcome of M. tuberculosis infection. We show here that administration of 1,25(OH)2D3 to M. tuberculosis infected mice led to a change in lung granuloma architecture, characterized by a marked decrease in B cell lymphocytic aggregates. Consistent with the altered granulomas, 1,25(OH)2D3-treated mice also exhibited significantly higher bacterial burden in the lungs compared to the control group. These findings highlight the need to further investigate the effect of vitamin D on host immunity to M. tuberculosis in the context of the granulomatous response. PMID- 27698451 TI - Co-acclimation of bacterial communities under stresses of hydrocarbons with different structures. AB - Crude oil is a complex mixture of hydrocarbons with different structures; its components vary in bioavailability and toxicity. It is important to understand how bacterial communities response to different hydrocarbons and their co acclimation in the process of degradation. In this study, microcosms with the addition of structurally different hydrocarbons were setup to investigate the successions of bacterial communities and the interactions between different bacterial taxa. Hydrocarbons were effectively degraded in all microcosms after 40 days. High-throughput sequencing offered a great quantity of data for analyzing successions of bacterial communities. The results indicated that the bacterial communities responded dramatically different to various hydrocarbons. KEGG database and PICRUSt were applied to predict functions of individual bacterial taxa and networks were constructed to analyze co-acclimations between functional bacterial groups. Almost all functional genes catalyzing degradation of different hydrocarbons were predicted in bacterial communities. Most of bacterial taxa were believed to conduct biodegradation processes via interactions with each other. This study addressed a few investigated area of bacterial community responses to structurally different organic pollutants and their co-acclimation and interactions in the process of biodegradation. The study could provide useful information to guide the bioremediation of crude oil pollution. PMID- 27698452 TI - Kupffer cells induce Notch-mediated hepatocyte conversion in a common mouse model of intrahepatic cholangiocarcinoma. AB - Intrahepatic cholangiocarcinoma (ICC) is a malignant epithelial neoplasm composed of cells resembling cholangiocytes that line the intrahepatic bile ducts in portal areas of the hepatic lobule. Although ICC has been defined as a tumor arising from cholangiocyte transformation, recent evidence from genetic lineage tracing experiments has indicated that hepatocytes can be a cellular origin of ICC by directly changing their fate to that of biliary lineage cells. Notch signaling has been identified as an essential factor for hepatocyte conversion into biliary lineage cells at the onset of ICC. However, the mechanisms underlying Notch signal activation in hepatocytes remain unclear. Here, using a mouse model of ICC, we found that hepatic macrophages called Kupffer cells transiently congregate around the central veins in the liver and express the Notch ligand Jagged-1 coincident with Notch activation in pericentral hepatocytes. Depletion of Kupffer cells prevents the Notch-mediated cell-fate conversion of hepatocytes to biliary lineage cells, inducing hepatocyte apoptosis and increasing mortality in mice. These findings will be useful for uncovering the pathogenic mechanism of ICC and developing prevenient and therapeutic strategies for this refractory disease. PMID- 27698454 TI - Self-assembled fibre optoelectronics with discrete translational symmetry. AB - Fibres with electronic and photonic properties are essential building blocks for functional fabrics with system level attributes. The scalability of thermal fibre drawing approach offers access to large device quantities, while constraining the devices to be translational symmetric. Lifting this symmetry to create discrete devices in fibres will increase their utility. Here, we draw, from a macroscopic preform, fibres that have three parallel internal non-contacting continuous domains; a semiconducting glass between two conductors. We then heat the fibre and generate a capillary fluid instability, resulting in the selective transformation of the cylindrical semiconducting domain into discrete spheres while keeping the conductive domains unchanged. The cylindrical-to-spherical expansion bridges the continuous conducting domains to create ~104 self assembled, electrically contacted and entirely packaged discrete spherical devices per metre of fibre. The photodetection and Mie resonance dependent response are measured by illuminating the fibre while connecting its ends to an electrical readout.

AB - Psychotherapy is often effective for treating psychogenic disorders, but the changes that occur in the brain during such treatments remain unknown. To investigate this, we monitored cerebral activity throughout an entire session using a psychotherapeutic technique in healthy subjects. Since post-traumatic stress disorder (PTSD) is a typical psychogenic psychiatric disorder, we used PTSD-model volunteers who had experienced a moderately traumatic event. The technique used as psychotherapy was eye movement desensitisation and reprocessing (EMDR), a standard method for treating PTSD. The oxygenated haemoglobin concentration ([oxy-Hb]), a sensitive index of brain activation, measured using multi-channel near-infrared spectroscopy, revealed changes in [oxy-Hb] in the superior temporal sulcus (STS) and orbitofrontal cortex (OFC). During a vital therapeutic stage, a significant reduction in the activation by forced eye movements was observed in the right STS, and a trend toward a reduction in the left OFC. The hyperactivation of the right STS on the recall of unpleasant memories, and its normalisation by eye movements, seem to reflect an important neural mechanism of the psychotherapy. These findings suggest that psychotherapy for traumatic symptoms involves brain regions related to memory representation and emotion, and possibly those that link memory and emotion, such as the amygdala. PMID- 27698455 TI - Tunable Resonators for Nonlinear Modal Interactions. AB - Understanding the various mechanisms of nonlinear mode coupling in micro and nano resonators has become an imminent necessity for their successful implementation in practical applications. However, consistent, repeatable, and flexible experimental procedures to produce nonlinear mode coupling are lacking, and hence research into well-controlled experimental conditions is crucial. Here, we demonstrate well-controlled and repeatable experiments to study nonlinear mode coupling among micro and nano beam resonators. Such experimental approach can be applied to other micro and nano structures to help study their nonlinear interactions and exploit them for higher sensitive and less noisy responses. Using electrothermal tuning and electrostatic excitation, we demonstrate three different kinds of nonlinear interactions among the first and third bending modes of vibrations of slightly curved beams (arches): two-one internal resonance, three-one internal resonance, and mode veering (near crossing). The experimental procedure is repeatable, highly flexible, do not require special or precise fabrication, and is conducted in air and at room temperature. This approach can be applied to other micro and nano structures, which come naturally curved due to fabrication imperfections, such as CNTs, and hence lays the foundation to deeply investigate the nonlinear mode coupling in these structures in a consistent way.

AB - Nb films are deposited on single crystal Al2O3 (110) and MgO(111) substrates by e beam evaporation technique. Structure of Nb films and orientation relationships (ORs) of Nb/Al2O3 and Nb/MgO interface are studied and compared by the combination of experiments and simulations. The experiments show that the Nb films obtain strong (110) texture, and the Nb film on Al2O3(110) substrate shows a higher crystalline quality than that on MgO(111) substrate. First principle calculations show that both the lattice mismatch and the strength of interface bonding play major roles in determining the crystalline perfection of Nb films and ORs between Nb films and single crystal ceramic substrates. The fundamental mechanisms for forming the interfacial configuration in terms of the lattice mismatch and the strength of interface bonding are discussed.

AB - To explore the evolutionary dynamics and molecular transmission patterns of HIV-1 CRF01_AE in depth among men who have sex with men (MSM) in Shanghai, we constructed phylogenetic tree and genetic transmission networks based on 1, 152 pol sequences from MSM, 282 from other risk groups and 795 references. Phylogenetic analyses identified two distinct major CRF01_AE lineages and a Shanghai-based sub-lineage. The estimated tMRCAs for lineage 1 and 2 were 1996.0 (1992.9-1999.2) and 1997.8 (1994.3-2001.4), respectively. Of the 1, 152 MSM, 681 (59.1%) were identified as belonging to 241 separate networks. Of these 681 individuals in networks, 74.2% were linked to cases diagnosed in different years, 4.3% were linked to heterosexual women, and 0.7% were linked to persons who inject drugs. A total of 71 networks including 180 individuals diagnosed in Shanghai with the same domicile were found. Recent infection (P = 0.022) and sampling year after 2011 (P < 0.001) were significantly associated with potential transmission links among the networks. Besides, a significant transmission of viruses with drug resistant mutations at V179D/E were found in the networks. Given these findings, we propose that genetic transmission analysis is a useful tool in HIV intervention strategies to curb the spread of virus and promoting public health. PMID- 27698459 TI - Prediction of phosphothreonine sites in human proteins by fusing different features. AB - Phosphorylation is one of the most important protein post-translation modifications. With the rapid development of high-throughput mass spectrometry, phosphorylation site data is rapidly accumulating, which provides us an opportunity to systematically investigate and predict phosphorylation in proteins. The phosphorylation of threonine is the addition of a phosphoryl group to its polar side chains group. In this work, we statistically analyzed the distribution of the different properties including position conservation, secondary structure, accessibility and some other physicochemical properties of the residues surrounding the phosphothreonine site and non-phosphothreonine site. We found that the distributions of those features are non-symmetrical. Based on the distribution of properties, we developed a new model by using optimal window size strategy and feature selection technique. The cross-validated results show that the area under receiver operating characteristic curve reaches to 0.847, suggesting that our model may play a complementary role to other existing methods for predicting phosphothreonine site in proteins. PMID- 27698456 TI - Microbial Degradation of Cellular Kinases Impairs Innate Immune Signaling and Paracrine TNFalpha Responses. AB - The NFkappaB and MAPK signaling pathways are critical components of innate immunity that orchestrate appropriate immune responses to control and eradicate pathogens. Their activation results in the induction of proinflammatory mediators, such as TNFalpha a potent bioactive molecule commonly secreted by recruited inflammatory cells, allowing for paracrine signaling at the site of an infection. In this study we identified a novel mechanism by which the opportunistic pathogen Porphyromonas gingivalis dampens innate immune responses by disruption of kinase signaling and degradation of inflammatory mediators. The intracellular immune kinases RIPK1, TAK1, and AKT were selectively degraded by the P. gingivalis lysine-specific gingipain (Kgp) in human endothelial cells, which correlated with dysregulated innate immune signaling. Kgp was also observed to attenuate endothelial responsiveness to TNFalpha, resulting in a reduction in signal flux through AKT, ERK and NFkappaB pathways, as well as a decrease in downstream proinflammatory mRNA induction of cytokines, chemokines and adhesion molecules. A deficiency in Kgp activity negated decreases to host cell kinase protein levels and responsiveness to TNFalpha. Given the essential role of kinase signaling in immune responses, these findings highlight a unique mechanism of pathogen-induced immune dysregulation through inhibition of cell activation, paracrine signaling, and dampened cellular proinflammatory responses.

Despite the massive human and financial toll of invasive insects, cost estimates of their impacts remain sporadic, spatially incomplete and of questionable quality. Here we compile a comprehensive database of economic costs of invasive insects. Taking all reported goods and service estimates, invasive insects cost a minimum of US$70.0 billion per year globally, while associated health costs exceed US$6.9 billion per year. Total costs rise as the number of estimate increases, although many of the worst costs have already been estimated (especially those related to human health). A lack of dedicated studies, especially for reproducible goods and service estimates, implies gross underestimation of global costs. Global warming as a consequence of climate change, rising human population densities and intensifying international trade will allow these costly insects to spread into new areas, but substantial savings could be achieved by increasing surveillance, containment and public awareness.

AB - Organic matter decomposition represents a vital ecosystem process by which nutrients are made available for plant uptake and is a major flux in the global carbon cycle. Previous studies have investigated decomposition of different plant parts, but few considered bark decomposition or its role in decomposition of wood. However, bark can comprise a large fraction of tree biomass. We used a common litter-bed approach to investigate factors affecting bark decomposition and its role in wood decomposition for five tree species in a secondary seasonal tropical rain forest in SW China. For bark, we implemented a litter bag experiment over 12 mo, using different mesh sizes to investigate effects of litter meso- and macro-fauna. For wood, we compared the decomposition of branches with and without bark over 24 mo. Bark in coarse mesh bags decomposed 1.11-1.76 times faster than bark in fine mesh bags. For wood decomposition, responses to bark removal were species dependent. Three species with slow wood decomposition rates showed significant negative effects of bark-removal, but there was no significant effect in the other two species. Future research should also separately examine bark and wood decomposition, and consider bark-removal experiments to better understand roles of bark in wood decomposition.

AB - In this study, hybrid perovskite solar cells are fabricated using poly[2-methoxy 5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) and poly(3-hexylthiophene 2,5-diyl) (P3HT) as dopant-free hole-transporting materials (HTMs), and two solution processes (one- and two-step methods, respectively) for preparing methylammonium lead iodide perovskite. By optimizing the concentrations and solvents of MEH-PPV solutions, a power conversion efficiency of 9.65% with hysteresis-less performance is achieved, while the device with 2,2',7,7' tetrakis(N,N-di-p-methoxyphenylamine)-9,9'spirobifluorene (Spiro-OMeTAD) doped with lithium salts and tert-butylpyridine (TBP) exhibits an efficiency of 13.38%. This result shows that non-doped MEH-PPV is a suitable, low-cost HTM for efficient polymer-based perovskite solar cells. The effect of different morphologies of methylammonium lead iodide perovskite on conversion efficiency is also investigated by incident photon-to-electron conversion efficiency (IPCE) curves and electrochemical impedance spectroscopy (EIS).

AB - To induce and sustain the leukaemogenic process, MLL-AF4+ leukaemia seems to require very few genetic alterations in addition to the fusion gene itself. Studies of infant and paediatric patients with MLL-AF4+ B cell precursor acute lymphoblastic leukaemia (BCP-ALL) have reported mutations in KRAS and NRAS with incidences ranging from 25 to 50%. Whereas previous studies employed Sanger sequencing, here we used next generation amplicon deep sequencing for in depth evaluation of RAS mutations in 36 paediatric patients at diagnosis of MLL-AF4+ leukaemia. RAS mutations including those in small sub-clones were detected in 63.9% of patients. Furthermore, the mutational analysis of 17 paired samples at diagnosis and relapse revealed complex RAS clone dynamics and showed that the mutated clones present at relapse were almost all originated from clones that were already detectable at diagnosis and survived to the initial therapy. Finally, we showed that mutated patients were indeed characterized by a RAS related signature at both transcriptional and protein levels and that the targeting of the RAS pathway could be of beneficial for treatment of MLL-AF4+ BCP ALL clones carrying somatic RAS mutations. PMID- 27698463 TI - High expression of new genes in trochophore enlightening the ontogeny and evolution of trochozoans. AB - Animals with trochophore larvae belong to Trochozoa, one of the main branches of Bilateria. In addition to exhibiting spiral cleavage and early cell fate determination, trochozoans typically undergo indirect development, which contributes to the most unique characteristics of their ontogeny. The indirect development of trochozoans has provoked discussion regarding the origin and evolution of marine larvae and is interesting from the perspective of phylogeny ontogeny correspondence. While these phylo-onto correlations have an hourglass shape in Deuterostomia, Ecdysozoa, plants and even fungi, they have seldom been studied in Trochozoa, and even Lophotrochozoa. Here, we compared the ontogenetic transcriptomes of the Pacific oyster, Crassostrea gigas (Bivalvia, Mollusca), the Pacific abalone, Haliotis discus hannai (Gastropoda, Mollusca), and the sand worm Perinereis aibuhitensis (Polychaeta, Annelida) using several complementary phylotranscriptomic methods to examine their evolutionary trajectories. The results revealed the late trochophore stage as the phylotypic phase. However, this basic pattern is accompanied with increased use of new genes in the trochophore stages which marks specific adaptations of the larval body plans. PMID- 27698465 TI - The polarization modulation and fabrication method of two dimensional silica photonic crystals based on UV nanoimprint lithography and hot imprint. AB - Based on a silica sol-gel technique, highly-structurally ordered silica photonic structures were fabricated by UV lithography and hot manual nanoimprint efforts, which makes large-scale fabrication of silica photonic crystals easy and results in low-cost. These photonic structures show perfect periodicity, smooth and flat surfaces and consistent aspect ratios, which are checked by scanning electron microscopy (SEM) and atomic force microscopy (AFM). In addition, glass substrates with imprinted photonic nanostructures show good diffraction performance in both transmission and reflection mode. Furthermore, the reflection efficiency can be enhanced by 5 nm Au nanoparticle coating, which does not affect the original imprint structure. Also the refractive index and dielectric constant of the imprinted silica is close to that of the dielectric layer in nanodevices. In addition, the polarization characteristics of the reflected light can be modulated by stripe nanostructures through changing the incident light angle. The experimental findings match with theoretical results, making silica photonic nanostructures functional integration layers in many optical or optoelectronic devices, such as LED and microlasers to enhance the optical performance and modulate polarization properties in an economical and large-scale way. PMID- 27698467 TI - Electrodynamic study of YIG filters and resonators. AB - Numerical solutions of coupled Maxwell and Landau-Lifshitz-Gilbert equations for a magnetized yttrium iron garnet (YIG) sphere acting as a one-stage filter are presented. The filter is analysed using finite-difference time-domain technique. Contrary to the state of the art, the study shows that the maximum electromagnetic power transmission through the YIG filter occurs at the frequency of the magnetic plasmon resonance with the effective permeability of the gyromagnetic medium MUr ~ -2, and not at a ferromagnetic resonance frequency. Such a new understanding of the YIG filter operation, makes it one of the most commonly used single-negative plasmonic metamaterials. The frequency of maximum transmission is also found to weakly depend on the size of the YIG sphere. An analytic electromagnetic analysis of resonances in a YIG sphere is performed for circularly polarized electromagnetic fields. The YIG sphere is situated in a free space and in a large spherical cavity. The study demonstrates that both volume resonances and magnetic plasmon resonances can be solutions of the same transcendental equations. PMID- 27698466 TI - Structural studies of the N-terminal fragments of the WW domain: Insights into co translational folding of a beta-sheet protein. AB - Nascent proteins fold co-translationally because the folding speed and folding pathways are limited by the rate of ribosome biosynthesis in the living cell. In addition, though full-length proteins can fold all their residues during the folding process, nascent proteins initially fold only with the N-terminal residues. However, the transient structure and the co-translational folding pathway are not well understood. Here we report the atomic structures of a series of N-terminal fragments of the WW domain with increasing amino acid length. Unexpectedly, the structures indicate that the intermediate-length fragments take helical conformations even though the full-length protein has no helical regions. The circular dichroism spectra and theoretical calculations also support the crystallographic results. This suggests that the short-range interactions are more decisive in the structure formation than the long-range interactions for short nascent proteins. In the course of the peptide extension, the helical structure change to the structure mediated by the long-range interactions at a particular polypeptide length. Our results will provide unique information for elucidating the nature of co-translational folding. PMID- 27698468 TI - Na+ compartmentalization related to salinity stress tolerance in upland cotton (Gossypium hirsutum) seedlings. AB - The capacity for ion compartmentalization among different tissues and cells is the key mechanism regulating salt tolerance in plants. In this study, we investigated the ion compartmentalization capacity of two upland cotton genotypes with different salt tolerances under salt shock at the tissue, cell and molecular levels. We found that the leaf glandular trichome could secrete more salt ions in the salt-tolerant genotype than in the sensitive genotype, demonstrating the excretion of ions from tissue may be a new mechanism to respond to short-term salt shock. Furthermore, an investigation of the ion distribution demonstrated that the ion content was significantly lower in critical tissues and cells of the salt-tolerant genotype, indicating the salt-tolerant genotype had a greater capacity for ion compartmentalization in the shoot. By comparing the membrane H+ ATPase activity and the expression of ion transportation-related genes, we found that the H+-ATPase activity and Na+/H+ antiporter are the key factors determining the capacity for ion compartmentalization in leaves, which might further determine the salt tolerance of cotton. The novel function of the glandular trichome and the comparison of Na+ compartmentalization between two cotton genotypes with contrasting salt tolerances provide a new understanding of the salt tolerance mechanism in cotton. PMID- 27698469 TI - High-resolution 3D volumetry versus conventional measuring techniques for the assessment of experimental lymphedema in the mouse hindlimb. AB - Secondary lymphedema is a common complication of cancer treatment characterized by chronic limb swelling with interstitial inflammation. The rodent hindlimb is a widely used model for the evaluation of novel lymphedema treatments. However, the assessment of limb volume in small animals is challenging. Recently, high resolution three-dimensional (3D) imaging modalities have been introduced for rodent limb volumetry. In the present study we evaluated the validity of microcomputed tomography (MUCT), magnetic resonance imaging (MRI) and ultrasound in comparison to conventional measuring techniques. For this purpose, acute lymphedema was induced in the mouse hindlimb by a modified popliteal lymphadenectomy. The 4-week course of this type of lymphedema was first assessed in 6 animals. In additional 12 animals, limb volumes were analyzed by MUCT, 9.4 T MRI and 30 MHz ultrasound as well as by planimetry, circumferential length and paw thickness measurements. Interobserver correlation was high for all modalities, in particular for MUCT analysis (r = 0.975, p < 0.001). Importantly, caliper-measured paw thickness correlated well with MUCT (r = 0.861), MRI (r = 0.821) and ultrasound (r = 0.800). Because the assessment of paw thickness represents a time- and cost-effective approach, it may be ideally suited for the quantification of rodent hindlimb lymphedema. PMID- 27698470 TI - Exome sequencing in the knockin mice generated using the CRISPR/Cas system. AB - Knockin (KI) mouse carrying a point mutation has been an invaluable tool for disease modeling and analysis. Genome editing technologies using the CRISPR/Cas system has emerged as an alternative way to create KI mice. However, if the mice carry nucleotide insertions and/or deletions (InDels) in other genes, which could have unintentionally occurred during the establishment of the KI mouse line and potentially have larger impact than a point mutation, it would confound phenotyping of the KI mice. In this study, we performed whole exome sequencing of multiple lines of F1 heterozygous Ntrk1 KI mice generated using the CRISPR/Cas system in comparison to that of a wild-type mouse used as a control. We found three InDels in four KI mice but not in a control mouse. In vitro digestion assay suggested that each InDel occurred as a de novo mutation, was carried-over from the parental mice, or was incorporated through the Cas9 nuclease mediated off target cleavage. These results suggest that frequency of InDels found in KI mice generated by the CRISPR/Cas technology is not high, but cannot be neglected and careful assessment of these mutations is warranted. PMID- 27698472 TI - Quantifying yield behaviour in metals by X-ray nanotomography. AB - Nanoindentation of engineering materials is commonly used to study, at small length scales, the continuum mechanical properties of elastic modulus and yield strength. However, it is difficult to measure strain hardening via nanoindentation. Strain hardening, which describes the increase in strength with plastic deformation, affects fracture toughness and ductility, and is an important engineering material property. The problem is that the load displacement data of a single nanoindentation do not provide a unique solution for the material's plastic properties, which can be described by its stress strain behaviour. Three-dimensional mapping of the displacement field beneath the indentation provides additional information that can overcome this difficulty. We have applied digital volume correlation of X-ray nano-tomographs of a nanoindentation to measure the sub-surface displacement field and so obtain the plastic properties of a nano-structured oxide dispersion strengthened steel. This steel has potential applications in advanced nuclear energy systems, and this novel method could characterise samples where proton irradiation of the surface simulates the effects of fast neutron damage, since facilities do not yet exist that can replicate this damage in bulk materials. PMID- 27698471 TI - Anti-tubulin drugs conjugated to anti-ErbB antibodies selectively radiosensitize. AB - Tumour resistance to radiotherapy remains a barrier to improving cancer patient outcomes. To overcome radioresistance, certain drugs have been found to sensitize cells to ionizing radiation (IR). In theory, more potent radiosensitizing drugs should increase tumour kill and improve patient outcomes. In practice, clinical utility of potent radiosensitizing drugs is curtailed by off-target side effects. Here we report potent anti-tubulin drugs conjugated to anti-ErbB antibodies selectively radiosensitize to tumours based on surface receptor expression. While two classes of potent anti-tubulins, auristatins and maytansinoids, indiscriminately radiosensitize tumour cells, conjugating these potent anti tubulins to anti-ErbB antibodies restrict their radiosensitizing capacity. Of translational significance, we report that a clinically used maytansinoid ADC, ado-trastuzumab emtansine (T-DM1), with IR prolongs tumour control in target expressing HER2+ tumours but not target negative tumours. In contrast to ErbB signal inhibition, our findings establish an alternative therapeutic paradigm for ErbB-based radiosensitization using antibodies to restrict radiosensitizer delivery. PMID- 27698473 TI - Apocynin and Nox2 regulate NF-kappaB by modifying thioredoxin-1 redox-state. AB - The reactive-oxygen-species-(ROS)-generating-enzyme Nox2 is essential for leukocyte anti-microbial activity. However its role in cellular redox homeostasis and, consequently, in modulating intracellular signaling pathways remains unclear. Herein, we show Nox2 activation favors thioredoxin-1 (TRX-1)/p40phox interaction, which leads to exclusion of TRX-1 from the nucleus. In contrast, the genetic deficiency of Nox2 or its pharmacological inhibition with apocynin (APO) results in reductive stress after lipopolysaccharide-(LPS)-cell stimulation, which causes nuclear accumulation of TRX-1 and enhanced transcription of inflammatory mediators through nuclear-factor-(NF)-kappaB. The NF-kappaB overactivation is prevented by TRX-1 oxidation using inhibitors of thioredoxin reductase-1 (TrxR-1). The Nox2/TRX-1/NF-kappaB intracellular signaling pathway is involved in the pathophysiology of chronic granulomatous disease (CGD) and sepsis. In fact, TrxR-1 inhibition prevents nuclear accumulation of TRX-1 and LPS stimulated hyperproduction of tumor-necrosis-factor-(TNF)-alpha by monocytes and neutrophils purified from blood of CGD patients, who have deficient Nox2 activity. TrxR-1 inhibitors, either lanthanum chloride (LaCl3) or auranofin (AUR), also increase survival rates of mice undergoing cecal-ligation-and puncture-(CLP). Therefore, our results identify a hitherto unrecognized Nox2 mediated intracellular signaling pathway that contributes to hyperinflammation in CGD and in septic patients. Additionally, we suggest that TrxR-1 inhibitors could be potential drugs to treat patients with sepsis, particularly in those with CGD. PMID- 27698474 TI - Structure of ubiquitylated-Rpn10 provides insight into its autoregulation mechanism. AB - Ubiquitin receptors decode ubiquitin signals into many cellular responses. Ubiquitin receptors also undergo coupled monoubiquitylation, and rapid deubiquitylation has hampered the characterization of the ubiquitylated state. Using bacteria that express a ubiquitylation apparatus, we purified and determined the crystal structure of the proteasomal ubiquitin-receptor Rpn10 in its ubiquitylated state. The structure shows a novel ubiquitin-binding patch that directs K84 ubiquitylation. Superimposition of ubiquitylated-Rpn10 onto electron microscopy models of proteasomes indicates that the Rpn10-conjugated ubiquitin clashes with Rpn9, suggesting that ubiquitylation might be involved in releasing Rpn10 from the proteasome. Indeed, ubiquitylation on immobilized proteasomes dissociates the modified Rpn10 from the complex, while unmodified Rpn10 mainly remains associated. In vivo experiments indicate that contrary to wild type, Rpn10-K84R is stably associated with the proteasomal subunit Rpn9. Similarly Rpn10, but not ubiquitylated-Rpn10, binds Rpn9 in vitro. Thus we suggest that ubiquitylation functions to dissociate modified ubiquitin receptors from their targets, a function that promotes cyclic activity of ubiquitin receptors. PMID- 27698476 TI - Wavelength-scale light concentrator made by direct 3D laser writing of polymer metamaterials. AB - We report on the realization of functional infrared light concentrators based on a thick layer of air-polymer metamaterial with controlled pore size gradients. The design features an optimum gradient index profile leading to light focusing in the Fresnel zone of the structures for two selected operating wavelength domains near 5.6 and 10.4 MUm. The metamaterial which consists in a thick polymer containing air holes with diameters ranging from lambda/20 to lambda/8 is made using a 3D lithography technique based on the two-photon polymerization of a homemade photopolymer. Infrared imaging of the structures reveals a tight focusing for both structures with a maximum local intensity increase by a factor of 2.5 for a concentrator volume of 1.5 lambda3, slightly limited by the residual absorption of the selected polymer. Such porous and flat metamaterial structures offer interesting perspectives to increase infrared detector performance at the pixel level for imaging or sensing applications. PMID- 27698475 TI - One-Pot Approach to Prepare Organo-silica Hybrid Capillary Monolithic Column with Intact Mesoporous Silica Nanoparticle as Building Block. AB - A facile "one-pot" approach to prepare organo-silica hybrid capillary monolithic column with intact mesoporous silica nanoparticle (IMSN) as crosslinker and building block was described. An IMSN crosslinked octadecyl-silica hybrid capillary monolithic column (IMSN-C18 monolithic column) was successfully prepared, and the effects of fabrication conditions (e.g. concentration of intact mesoporous silica nanoparticle, polycondensation temperature, content of vinyltrimethoxysilane and stearyl methacrylate) on the structures of the IMSN-C18 monolithic column were studied in detail. The IMSN-C18 hybrid monolithic column possessed uniform morphology, good mechanical and pH stability (pH 1.1-11), which was applied to the separations of alkyl benzenes, polycyclic aromatic hydrocarbons (PAHs), as well as proteins. The minimum plate height of 10.5 MUm (corresponding to 95000 N m-1) for butylbenzene and high reproducibility were achieved. The analysis of tryptic digest of bovine serum albumin (BSA) was carried out on the IMSN-C18 monolithic column by cLC coupled mass spectrometry (cLC-MS/MS), with the protein sequence coverage of 87.5% for BSA, demonstrating its potential application in proteomics. PMID- 27698477 TI - A novel injectable BRET-based in vivo imaging probe for detecting the activity of hypoxia-inducible factor regulated by the ubiquitin-proteasome system. AB - The ubiquitin-proteasome system (UPS) is a selective protein degradation system that plays a critical role in many essential biological processes by regulating the existence of various cellular proteins. The target proteins of UPS are recognized and tagged with polyubiquitin chains by E3 ubiquitin ligases, which have high substrate-specific activities. Here we present a novel injectable imaging probe POL-N that can detect the UPS-regulated hypoxia-inducible factor (HIF) activity in vivo. Because the luciferase is fused to the E3 ligase recognition domain of the HIF-1alpha, POL-N is intact only in the HIFalpha overexpressing cells, that is, HIF-active cells, generating signals via an intramolecular bioluminescence resonance energy transfer (BRET) between luciferase and a near-infrared (NIR) fluorescent dye at the C-terminal end of the probe. Off-target signals of the NIR-BRET were so low that we could achieve highly sensitive and fast detection of intratumoral HIF-activity. Notably, we successfully detected hypoxic liver metastasis, which is extremely difficult to detect by injectable imaging probes due to strong off-target signals, as early as 1 h after systemic injection of POL-N. Our probe design can be widely adapted to UPS-target proteins and may contribute to the exploration of their roles in animal disease models. PMID- 27698478 TI - Oscillating edge states in one-dimensional MoS2 nanowires. AB - Reducing the dimensionality of transition metal dichalcogenides to one dimension opens it to structural and electronic modulation related to charge density wave and quantum correlation effects arising from edge states. The greater flexibility of a molecular scale nanowire allows a strain-imposing substrate to exert structural and electronic modulation on it, leading to an interplay between the curvature-induced influences and intrinsic ground-state topology. Herein, the templated growth of MoS2 nanowire arrays consisting of the smallest stoichiometric MoS2 building blocks is investigated using scanning tunnelling microscopy and non-contact atomic force microscopy. Our results show that lattice strain imposed on a nanowire causes the energy of the edge states to oscillate periodically along its length in phase with the period of the substrate topographical modulation. This periodic oscillation vanishes when individual MoS2 nanowires join to form a wider nanoribbon, revealing that the strain-induced modulation depends on in-plane rigidity, which increases with system size. PMID- 27698479 TI - Multiphoton imaging reveals that nanosecond pulsed electric fields collapse tumor and normal vascular perfusion in human glioblastoma xenografts. AB - Despite the biomedical advances of the last century, many cancers including glioblastoma are still resistant to existing therapies leaving patients with poor prognoses. Nanosecond pulsed electric fields (nsPEF) are a promising technology for the treatment of cancer that have thus far been evaluated in vitro and in superficial malignancies. In this paper, we develop a tumor organoid model of glioblastoma and apply intravital multiphoton microscopy to assess their response to nsPEFs. We demonstrate for the first time that a single 10 ns, high voltage electric pulse (35-45 kV/cm), collapses the perfusion of neovasculature, and also alters the diameter of capillaries and larger vessels in normal tissue. These results contribute to the fundamental understanding of nsPEF effects in complex tissue environments, and confirm the potential of nsPEFs to disrupt the microenvironment of solid tumors such as glioblastoma. PMID- 27698481 TI - Hydrogen-bonding Interactions between Apigenin and Ethanol/Water: A Theoretical Study. AB - In this work, hydrogen-bonding interactions between apigenin and water/ethanol were investigated from a theoretical perspective using quantum chemical calculations. Two conformations of apigenin molecule were considered in this work. The following results were found. (1) For apigenin monomer, the molecular structure is non-planar, and all of the hydrogen and oxygen atoms can be hydrogen bonding sites. (2) Eight and seven optimized geometries are obtained for apigenin (I)-H2O/CH3CH2OH and apigenin (II)-H2O/CH3CH2OH complexes, respectively. In apigenin, excluding the aromatic hydrogen atoms in the phenyl substituent, all other hydrogen atoms and the oxygen atoms form hydrogen-bonds with H2O and CH3CH2OH. (3) In apigenin-H2O/CH3CH2OH complexes, the electron density and the E(2) in the related localized anti-bonding orbital are increased upon hydrogen bond formation. These are the cause of the elongation and red-shift of the X-H bond. The sum of the charge change transfers from the hydrogen-bond acceptor to donor. The stronger interaction makes the charge change more intense than in the less stable structures. (4) Most of the hydrogen-bonds in the complexes are electrostatic in nature. However, the C4-O5...H, C9-O4...H and C13-O2...H hydrogen-bonds have some degree of covalent character. Furthermore, the hydroxyl groups of the apigenin molecule are the preferred hydrogen-bonding sites. PMID- 27698480 TI - Mode of renal replacement therapy determines endotoxemia and neutrophil dysfunction in chronic kidney disease. AB - Bacterial infection and sepsis are common complications of chronic kidney disease (CKD). A vicious cycle of increased gut permeability, endotoxemia, inadequate activation of the innate immune system and resulting innate immune dysfunction is hypothesized. We assessed endotoxemia, neutrophil function and its relation to oxidative stress, inflammation and gut permeability in patients with CKD grade 3 5 without renal replacement therapy (CKD group, n = 57), patients with CKD stage 5 undergoing haemodialysis (HD, n = 32) or peritoneal dialysis (PD, n = 28) and patients after kidney transplantation (KT, n = 67) in a cross-sectional observational study. In HD patients, endotoxin serum levels were elevated and neutrophil phagocytic capacity was decreased compared to all other groups. Patients on HD had a significantly higher mortality, due to infections during follow up, compared to PD (p = 0.022). Oxidative stress, neutrophil energy charge, systemic inflammation and gut permeability could not completely explain these differences. Our findings suggest that dialysis modality and not renal function per se determine the development of neutrophil dysfunction and endotoxemia in CKD-patients. HD patients are particularly prone to neutrophil dysfunction and endotoxemia whereas neutrophil function seems to improve after KT. Multi-target approaches are therefore warranted to improve neutrophil function and potentially reduce the rate of infections with patients undergoing haemodialysis. PMID- 27698482 TI - Elevation in fibroblast growth factor 23 and its value for identifying subclinical atherosclerosis in first-degree relatives of patients with diabetes. AB - Accumulating evidence supported an association between diabetes and fibroblast growth factor 23 (FGF23). The goal of the present study was to explore alteration in serum FGF23 levels and to assess its value for identifying subclinical atherosclerosis in normoglycemic individuals with a first-degree family history of diabetes (FHD). The study enrolled 312 subjects with a first-degree FHD and 1407 subjects without an FHD. Serum FGF23 levels were detected by a sandwich enzyme-linked immunosorbent assay. Serum FGF23 levels were much higher in subjects with a first-degree FHD than in those without an FHD (P = 0.006). A first-degree FHD was positively associated with serum FGF23 levels, independent of C-IMT and cardiovascular factors (both P < 0.05). In subjects with a first degree FHD, only those with serum FGF23 levels in the upper quartile were more likely to have an increased C-IMT (odds ratio = 2.263, P < 0.05). As conclusions, a first-degree FHD contributes to the increased serum FGF23 levels independently. Subjects with a first-degree FHD need higher serum FGF23 levels to indicate subclinical atherosclerosis. The influence of a first-degree FHD on serum FGF23 levels should be considered to avoid overestimating the risk of cardiovascular disease in normoglycemic individuals with a first-degree FHD. PMID- 27698483 TI - Comparative and parallel genome-wide association studies for metabolic and agronomic traits in cereals. AB - The plant metabolome is characterized by extensive diversity and is often regarded as a bridge between genome and phenome. Here we report metabolic and phenotypic genome-wide studies (mGWAS and pGWAS) in rice grain that, in addition to previous metabolic GWAS in rice leaf and maize kernel, show both distinct and overlapping aspects of genetic control of metabolism within and between species. We identify new candidate genes potentially influencing important metabolic and/or morphological traits. We show that the differential genetic architecture of rice metabolism between different tissues is in part determined by tissue specific expression. Using parallel mGWAS and pGWAS we identify new candidate genes potentially responsible for variation in traits such as grain colour and size, and provide evidence of metabotype-phenotype linkage. Our study demonstrates a powerful strategy for interactive functional genomics and metabolomics in plants, especially the cloning of minor QTLs for complex phenotypic traits. PMID- 27698484 TI - Measuring cell surface area and deformability of individual human red blood cells over blood storage using quantitative phase imaging. AB - The functionality and viability of stored human red blood cells (RBCs) is an important clinical issue in transfusions. To systematically investigate changes in stored whole blood, the hematological properties of individual RBCs were quantified in blood samples stored for various periods with and without a preservation solution called citrate phosphate dextrose adenine-1 (CPDA-1). With 3-D quantitative phase imaging techniques, the optical measurements for 3-D refractive index (RI) distributions and membrane fluctuations were done at the individual cell level. From the optical measurements, the morphological (volume, surface area and sphericity), biochemical (hemoglobin content and concentration), and mechanical parameters (dynamic membrane fluctuation) were simultaneously quantified to investigate the functionalities and progressive alterations of stored RBCs. Our results show that stored RBCs without CPDA-1 had a dramatic morphological transformation from discocytes to spherocytes within two weeks which was accompanied by significant decreases in cell deformability and cell surface area, and increases in sphericity. However, the stored RBCs with CPDA-1 maintained their morphology and deformability for up to 6 weeks. PMID- 27698485 TI - Applying high-resolution melting (HRM) technology to identify five commonly used Artemisia species. AB - Many members of the genus Artemisia are important for medicinal purposes with multiple pharmacological properties. Often, these herbal plants sold on the markets are in processed forms so it is difficult to authenticate. Routine testing and identification of these herbal materials should be performed to ensure that the raw materials used in pharmaceutical products are suitable for their intended use. In this study, five commonly used Artemisia species included Artemisia argyi, Artemisia annua, Artemisia lavandulaefolia, Artemisia indica, and Artemisia atrovirens were analyzed using high resolution melting (HRM) analysis based on the internal transcribed spacer 2 (ITS2) sequences. The melting profiles of the ITS2 amplicons of the five closely related herbal species are clearly separated so that they can be differentiated by HRM method. The method was further applied to authenticate commercial products in powdered. HRM curves of all the commercial samples tested are similar to the botanical species as labeled. These congeneric medicinal products were also clearly separated using the neighbor-joining (NJ) tree. Therefore, HRM method could provide an efficient and reliable authentication system to distinguish these commonly used Artemisia herbal products on the markets and offer a technical reference for medicines quality control in the drug supply chain. PMID- 27698486 TI - Similar contrast sensitivity functions measured using psychophysics and optokinetic nystagmus. AB - Although the contrast sensitivity function (CSF) is a particularly useful way of characterising functional vision, its measurement relies on observers making reliable perceptual reports. Such procedures can be challenging when testing children. Here we describe a system for measuring the CSF using an automated analysis of optokinetic nystagmus (OKN); an involuntary oscillatory eye movement made in response to drifting stimuli, here spatial-frequency (SF) band-pass noise. Quantifying the strength of OKN in the stimulus direction allows us to estimate contrast sensitivity across a range of SFs. We compared the CSFs of 30 observers with normal vision measured using both OKN and perceptual report. The approaches yield near-identical CSFs (mean R = 0.95) that capture subtle intra observer variations in visual acuity and contrast sensitivity (both R = 0.84, p < 0.0001). Trial-by-trial analysis reveals high correlation between OKN and perceptual report, a signature of a common neural mechanism for determining stimulus direction. We also observe conditions where OKN and report are significantly decorrelated as a result of a minority of observers experiencing direction-reversals that are not reflected by OKN. We conclude that there are a wide range of stimulus conditions for which OKN can provide a valid alternative means of measuring of the CSF.

AB - The Rauhut-Currier (RC) reaction represents an efficient method for the construction of carbon-carbon bond in organic synthesis. However, the RC reactions involving allenoate substrates are very rare, and in particular, asymmetric intramolecular RC reaction of allenoates is yet to be discovered. Here, we show that the intramolecular RC reaction proceeds smoothly in the presence of 1 mol% beta-ICD, and bicyclic lactones are obtained in high yields and with excellent enantiomeric excesses. With the employment of gamma substituted allenoates as racemic precursors, a novel dynamic kinetic resolution of allenes via RC reaction is observed, which allows for facile synthesis of highly enantiomerically enriched allenes. PMID- 27698488 TI - Insights into cancer severity from biomolecular interaction mechanisms. AB - To attain a deeper understanding of diseases like cancer, it is critical to couple genetics with biomolecular mechanisms. High-throughput sequencing has identified thousands of somatic mutations across dozens of cancers, and there is a pressing need to identify the few that are pathologically relevant. Here we use protein structure and interaction data to interrogate nonsynonymous somatic cancer mutations, identifying a set of 213 molecular interfaces (protein-protein, -small molecule or -nucleic acid) most often perturbed in cancer, highlighting several potentially novel cancer genes. Over half of these interfaces involve protein-small-molecule interactions highlighting their overall importance in cancer. We found distinct differences in the predominance of perturbed interfaces between cancers and histological subtypes and presence or absence of certain interfaces appears to correlate with cancer severity. PMID- 27698490 TI - A fossil biting midge (Diptera: Ceratopogonidae) from early Eocene Indian amber with a complex pheromone evaporator. AB - The life-like fidelity of organisms captured in amber is unique among all kinds of fossilization and represents an invaluable source for different fields of palaeontological and biological research. One of the most challenging aspects in amber research is the study of traits related to behaviour. Here, indirect evidence for pheromone-mediated mating behaviour is recorded from a biting midge (Ceratopogonidae) in 54 million-year-old Indian amber. Camptopterohelea odora n. sp. exhibits a complex, pocket shaped structure on the wings, which resembles the wing folds of certain moth flies (Diptera: Psychodidae) and scent organs that are only known from butterflies and moths (Lepidoptera) so far. Our studies suggests that pheromone releasing structures on the wings have evolved independently in biting midges and might be much more widespread in fossil as well as modern insects than known so far. PMID- 27698489 TI - Upregulation of ANGPTL6 in mouse keratinocytes enhances susceptibility to psoriasis. AB - Psoriasis is a chronic inflammatory skin disease marked by aberrant tissue repair. Mutant mice modeling psoriasis skin characteristics have provided useful information relevant to molecular mechanisms and could serve to evaluate therapeutic strategies. Here, we found that epidermal ANGPTL6 expression was markedly induced during tissue repair in mice. Analysis of mice overexpressing ANGPTL6 in keratinocytes (K14-Angptl6 Tg mice) revealed that epidermal ANGPTL6 activity promotes aberrant epidermal barrier function due to hyperproliferation of prematurely differentiated keratinocytes. Moreover, skin tissues of K14 Angptl6 Tg mice showed aberrantly activated skin tissue inflammation seen in psoriasis. Levels of the proteins S100A9, recently proposed as therapeutic targets for psoriasis, also increased in skin tissue of K14-Angptl6 Tg mice, but psoriasis-like inflammatory phenotypes in those mice were not rescued by S100A9 deletion. This finding suggests that decreasing S100A9 levels may not ameliorate all cases of psoriasis and that diverse mechanisms underlie the condition. Finally, we observed enhanced levels of epidermal ANGPTL6 in tissue specimens from some psoriasis patients. We conclude that the K14-Angptl6 Tg mouse is useful to investigate psoriasis pathogenesis and for preclinical testing of new therapeutics. Our study also suggests that ANGPTL6 activation in keratinocytes enhances psoriasis susceptibility. PMID- 27698492 TI - First Direct Evidence of Long-distance Seasonal Movements and Hibernation in a Migratory Bat. AB - Understanding of migration in small bats has been constrained by limitations of techniques that were labor-intensive, provided coarse levels of resolution, or were limited to population-level inferences. Knowledge of movements and behaviors of individual bats have been unknowable because of limitations in size of tracking devices and methods to attach them for long periods. We used sutures to attach miniature global positioning system (GPS) tags and data loggers that recorded light levels, activity, and temperature to male hoary bats (Lasiurus cinereus). Results from recovered GPS tags illustrated profound differences among movement patterns by individuals, including one that completed a >1000 km round trip journey during October 2014. Data loggers allowed us to record sub-hourly patterns of activity and torpor use, in one case over a period of 224 days that spanned an entire winter. In this latter bat, we documented 5 torpor bouts that lasted >=16 days and a flightless period that lasted 40 nights. These first uses of miniature tags on small bats allowed us to discover that male hoary bats can make multi-directional movements during the migratory season and sometimes hibernate for an entire winter. PMID- 27698493 TI - Printed 2 V-operating organic inverter arrays employing a small-molecule/polymer blend. AB - Printed organic thin-film transistors (OTFTs) are well suited for low-cost electronic applications, such as radio frequency identification (RFID) tags and sensors. Achieving both high carrier mobility and uniform electrical characteristics in printed OTFT devices is essential in these applications. Here, we report on printed high-performance OTFTs and circuits using silver nanoparticle inks for the source/drain electrodes and a blend of dithieno[2,3 d;2',3'-d']benzo[1,2-b;4,5-b']dithiophene (DTBDT-C6) and polystyrene for the organic semiconducting layer. A high saturation region mobility of 1.0 cm2 V-1 s 1 at low operation voltage of -5 V was obtained for relatively short channel lengths of 9 MUm. All fifteen of the printed pseudo-CMOS inverter circuits were formed on a common substrate and operated at low operation voltage of 2 V with the total variation in threshold voltage of 0.35 V. Consequently, the printed OTFT devices can be used in more complex integrated circuit applications requiring low manufacturing cost over large areas. PMID- 27698491 TI - Escherichia coli Braun Lipoprotein (BLP) exhibits endotoxemia - like pathology in Swiss albino mice. AB - The endotoxin lipopolysaccharide (LPS) promotes sepsis, but bacterial peptides also promote inflammation leading to sepsis. We found, intraperitoneal administration of live or heat inactivated E. coli JE5505 lacking the abundant outer membrane protein, Braun lipoprotein (BLP), was less toxic than E. coli DH5alpha possessing BLP in Swiss albino mice. Injection of BLP free of LPS purified from E. coli DH5alpha induced massive infiltration of leukocytes in lungs and liver. BLP activated human polymorphonuclear cells (PMNs) ex vivo to adhere to denatured collagen in serum and polymyxin B independent fashion, a property distinct from LPS. Both LPS and BLP stimulated the synthesis of platelet activating factor (PAF), a potent lipid mediator, in human PMNs. In mouse macrophage cell line, RAW264.7, while both BLP and LPS similarly upregulated TNF alpha and IL-1beta mRNA; BLP was more potent in inducing cyclooxygenase-2 (COX-2) mRNA and protein expression. Peritoneal macrophages from TLR2-/- mice significantly reduced the production of TNF-alpha in response to BLP in contrast to macrophages from wild type mice. We conclude, BLP acting through TLR2, is a potent inducer of inflammation with a response profile both common and distinct from LPS. Hence, BLP mediated pathway may also be considered as an effective target against sepsis. PMID- 27698496 TI - Surrogate Markers and Drug Approvals. PMID- 27698495 TI - The Oncoprotein BRD4-NUT Generates Aberrant Histone Modification Patterns. AB - Defects in chromatin proteins frequently manifest in diseases. A striking case of a chromatin-centric disease is NUT-midline carcinoma (NMC), which is characterized by expression of NUT as a fusion partner most frequently with BRD4. ChIP-sequencing studies from NMC patients revealed that BRD4-NUT (B4N) covers large genomic regions and elevates transcription within these domains. To investigate how B4N modulates chromatin, we performed affinity purification of B4N when ectopically expressed in 293-TREx cells and quantified the associated histone posttranslational modifications (PTM) using proteomics. We observed significant enrichment of acetylation particularly on H3 K18 and of combinatorial patterns such as H3 K27 acetylation paired with K36 methylation. We postulate that B4N complexes override the preexisting histone code with new PTM patterns that reflect aberrant transcription and that epigenetically modulate the nucleosome environment toward the NMC state.

PMID- 27698494 TI - Regulation of the Abundance of Kaposi's Sarcoma-Associated Herpesvirus ORF50 Protein by Oncoprotein MDM2. AB - The switch between latency and the lytic cycle of Kaposi's sarcoma-associated herpesvirus (KSHV) is controlled by the expression of virally encoded ORF50 protein. Thus far, the regulatory mechanism underlying the protein stability of ORF50 is unknown. Our earlier studies have demonstrated that a protein abundance regulatory signal (PARS) at the ORF50 C-terminal region modulates its protein abundance. The PARS region consists of PARS-I (aa 490-535) and PARS-II (aa 590 650), and mutations in either component result in abundant expression of ORF50. Here, we show that ORF50 protein is polyubiquitinated and its abundance is controlled through the proteasomal degradation pathway. The PARS-I motif mainly functions as a nuclear localization signal in the control of ORF50 abundance, whereas the PARS-II motif is required for the binding of ubiquitin enzymes in the nucleus. We find that human oncoprotein MDM2, an ubiquitin E3 ligase, is capable of interacting with ORF50 and promoting ORF50 degradation in cells. The interaction domains between both proteins are mapped to the PARS region of ORF50 and the N-terminal 220-aa region of MDM2. Additionally, we identify lysine residues at positions 152 and 154 in the N-terminal domain of ORF50 critically involved in MDM2-mediated downregulation of ORF50 levels. Within KSHV-infected cells, the levels of MDM2 were greatly reduced during viral lytic cycle and genetic knockdown of MDM2 in these cells favored the enhancement of ORF50 expression, supporting that MDM2 is a negative regulator of ORF50 expression. Collectively, the study elucidates the regulatory mechanism of ORF50 stability and implicates that MDM2 may have a significant role in the maintenance of viral latency by lowering basal level of ORF50.

PMID- 27698502 TI - Leadership Book Club: An Innovative Strategy to Incorporate Leadership Development Into Pharmacy Residency Programs. AB - Purpose: To describe an innovative strategy for incorporating leadership training and development across multiple postgraduate year 2 (PGY2) pharmacy residency programs at a single institution. Background: Tampa General Hospital has 7 pharmacy residency positions: 4 postgraduate year 1 (PGY1) residents and a single resident for each of the 3 PGY2 programs (critical care, emergency medicine, and solid organ transplant). Administrative topics are incorporated across the PGY1 and PGY2 residency programs, with each PGY2 program having additional administrative topics specific to their specialty area. Summary: What began as an elective administrative topic discussion for the PGY2 emergency medicine resident has evolved over time into a longitudinal leadership book club. The leadership book club is utilized to meet the residency goals and objectives related to leadership development for all 3 PGY2 programs. Each year a single book is identified through the American Society of Health-System Pharmacists (ASHP) Leadership Academy book list or by participant suggestion. The book is then divided into 4 sections with corresponding hour-long discussions that occur quarterly throughout the residency year. The residency program directors (RPDs) and co-RPDs lead the initial discussion, and each PGY2 resident leads 1 of the subsequent 3 discussions. Based on resident feedback, the leadership book club is an innovative and effective strategy to incorporate leadership training and development into residency training. Conclusion: It is imperative to foster the development of leadership skills in pharmacy residency programs to prevent a future leadership gap in health system pharmacy. Leadership book club is a unique strategy to incorporate leadership training longitudinally across multiple PGY2 residency programs at a single institution. PMID- 27698503 TI - Impact of a Pharmacy-Led Pain Management Team on Adults in an Academic Medical Center. AB - Background: Pain is a major health problem affecting more than 15% of adults in the United States. In a multidisciplinary pain management team, pharmacists can optimize pharmacotherapy quality by ensuring safe and appropriate medication use. Objective: Assess the impact of a pharmacy pain medication management service on pain-related outcomes in an adult inpatient population. Methods: This retrospective study evaluated patients who were admitted from November 2009 through November 2011 and received a pharmacy pain consult. Patients were excluded if they left against medical advice, their care was assumed by palliative care, or they had no complaint of pain when seen by the pharmacist. The primary outcome was the difference between each patient's average pain score from pre-consult to post-consult. Secondary outcomes were difference between each patient's average pain score from pre-consult to pre-discharge, overall functional improvement, pharmacist interventions, and 14-day and 30-day readmissions. Results: One hundred patients were included in the final analysis. Eight hundred twenty-one interventions were made by the clinical pharmacists. Patients displayed a significant reduction in their pre- and post-consult pain intensity scores on a 0 to 10 numerical rating scale (6.15 vs 3.25; p < .001). Likewise, a significant reduction in pain intensity scores was seen from pre consult to pre-discharge (6.15 vs 3.6; p < .001). Overall functional improvement, specifically sleep, mobility, and appetite, was seen in 86.6% of patients. Conclusions: Pain management is an area that provides opportunities for pharmacotherapy interventions. Pharmacists' involvement in pain management on an inpatient consult service had a positive impact on pain scores and improvement in functionality. PMID- 27698504 TI - Impact of Medication Dose Tracking Technology on Nursing Practice. AB - Objective: The impact of providing nursing staff access to data collected through a medication dose tracking technology (MDTT) web portal was investigated. Methods: A quasi-experimental, nonrandomized, pre-post intervention study was conducted in the Cardiothoracic Intensive Care Unit (CTICU) at Duke University Hospital. The change in the number of medication requests per dispense routed to the pharmacy electronic health record (EHR) in-basket was analyzed pre and post web portal access. Other endpoints included the number of MDTT web portal queries per day by nursing staff, change in nursing satisfaction survey scores, and technician time associated with processing medication requests pre and post web portal access. The pre web portal access phase of the study occurred from June 1, 2014 to August 31, 2014. The post web portal access phase occurred from October 1, 2014 to December 31, 2014. Results: An 11.4% decrease in the number of medication requests per dispense was exhibited between the pre and post web portal access phases of the study (0.0579 vs 0.0513, respectively; p < .001). Pre and post surveys showed a significant improvement in nurses' satisfaction regarding access to information on the location of medications (p = .009). Additionally, CTICU nursing staff utilized the MDTT web portal for 3.21 queries per day from October 1, 2014 to December 31, 2014. Conclusion: Providing nurses access to data collected via an MDTT decreased the number of communications between nursing and pharmacy staff regarding medication availability and led to statistically significant improvements in nursing satisfaction for certain aspects of the medication distribution process. PMID- 27698505 TI - Guidelines for the Establishment of Appropriate Beyond Use Dating of Sterile Compounded Admixtures. AB - To support compounding of products that are sterile and chemically stable, beyond use dating of admixtures must include a thorough evaluation of appropriate resources. In most instances, resources provide documentation of a specific compounded admixture, at a specific concentration and storage parameters, that does not coincide with current operations or patient-specific requirements. To meet the operational demands of a pharmacy, institutions employ a referenced guideline approach to guide decision making for safe sterile admixing. Often these guidelines are established and maintained at individual practicing locations with varying levels of detail and accuracy. In an effort to improve sterile compounding across a multihospital system, we developed and implemented beyond use dating guidelines to improve consistency and patient safety while meeting regulatory concerns. PMID- 27698506 TI - Comparison of Time to Therapeutic aPTT in Patients Who Received Continuous Unfractionated Heparin After Implementation of Pharmacy-wide Intervention Alerts. AB - Background: For patients on continuous IV unfractionated heparin (UFH), failing to achieve a therapeutic aPTT by 24 hours can be associated with increased morbidity. A pharmacy clinical surveillance system (PCSS) subtherapeutic aPTT alert was implemented at our institution to improve achievement of therapeutic aPTT goals by 24 hours. Objective: The primary objective was the time to achieve the minimum goal aPTT before and after the alert implementation. The secondary objectives were to examine the percentage of patients who achieved the minimum goal aPTT by 24 hours and the number of dose changes to achieve the minimum goal aPTT. Methods: A single-center retrospective study was conducted to include all adult inpatients receiving a continuous UFH infusion during a 3-month period prior to the implementation of a subtherapeutic aPTT alert and a 3-month period after implementation. Results: 317 patients were included in the analysis. The average time to achieve the minimum goal aPTT was 21.8 hours prior to alert implementation and 15.4 hours after implementation (p = .002). The percent of patients who achieved the minimum goal aPTT by 24 hours was 65.7% prior to alert implementation and 82.4% after implementation (p = .035). The average number of dose changes necessary to achieve aPTT value to the minimum goal aPTT prior to alert implementation was 1.67 and 1. 98 after implementation (p = .68). Conclusion: This analysis showed that implementation of a PCSS subtherapeutic aPTT alert for patients on continuous UFH infusions may ensure patients reach goal aPTT faster and facilitate a higher percent of patients who achieve the minimum goal aPTT by 24 hours. PMID- 27698507 TI - Case Study of Fatal Stroke Following Intranasal Lidocaine. AB - A 39-year-old man presented with new onset right hemiparesis and aphasia within an hour of using approximately 120 mL lidocaine 4% topical solution intranasally. Lidocaine had been prescribed over a 3-week period for pain due to multiple debridements of the nasal septum. A total of 650 mL of 4% lidocaine (26 g) had been dispensed to the patient during this time. The patient had a significant history of drug abuse, including snorting crushed tablets. Otherwise he was a healthy man with no chronic diseases or conditions. On arrival, and from previous exams, EKGs were normal without conduction delays. Electrolytes and CBC results were within normal range. The MRI/MRA showed a new thrombus with left middle cerebral artery distribution affecting one-third of the brain mass, including brain stem. Lidocaine likely contributed to cardiovascular embolic development, possibly from a sudden drop in blood pressure and known cardiovascular effects of sodium channel blockade. The patient expired from acute respiratory failure secondary to brainstem damage. Solutions of topical lidocaine should not be prescribed for use on open wounds or abraded skin as drug absorption will be increased, especially in highly vascularized nasal passages.

Boxed warnings (http://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guida ces/ucm075096.pdf) are ordinarily used to highlight either adverse reactions so serious in proportion to the potential benefit from the drug that it is essential that it be considered in assessing the risks and benefits of using the drugs or serious adverse reactions that can be prevented/reduced in frequency or severity by appropriate use of the drug; or FDA approved the drug with restrictions to ensure safe use because FDA concluded that the drug can be safely used only if distribution or use is restricted. There were 10 revised boxed warnings and 1 drug class change from April through June 2016. PMID- 27698511 TI - Consider Adopting Collaborative Project Management Software.

PMID- 27698512 TI - Precautionary Savings in Mexico: Evidence from the Mexican Health and Aging Study. AB - Precautionary saving is the additional saving done by individuals to protect them financially in situations of uncertainty and reduce their vulnerability for negative shocks that may affect their consumption levels. This paper investigates the existence and extent of savings motivated by precaution in Mexico for people aged between 50 and 75, using data from the Mexican Health and Ageing Study 2003. The empirical strategy is based on a test of the direct relationship between the accumulated wealth and the uncertainty generated by the social security status, in particular the availability of health insurance, accounting also for the expectation to receive a retirement pension. The endogeneity-corrected estimates do not yield results that unequivocally support the existence of private savings as a risk protection mechanism, implying that the public protection system has an important role in reducing the vulnerability of the population studied. PMID- 27698513 TI - On the origin of carbon dioxide released from rewetted soils. AB - When dry soils are rewetted a pulse of CO2 is invariably released, and whilst this phenomenon has been studied for decades, the precise origins of this CO2 remain obscure. We postulate that it could be of chemical (i.e. via abiotic pathways), biochemical (via free enzymes) or biological (via intact cells) origin. To elucidate the relative contributions of the pathways, dry soils were either sterilised (double autoclaving) or treated with solutions of inhibitors (15% trichloroacetic acid or 1% silver nitrate) targeting the different modes. The rapidity of CO2 release from the soils after the drying:rewetting (DRW) cycle was remarkable, with maximal rates of evolution within 6 min, and 41% of the total efflux over 96 h released within the first 24 h. The complete cessation of CO2 eflux following sterilisation showed there was no abiotic (dissolution of carbonates) contribution to the CO2 release on rewetting, and clear evidence for an organismal or biochemical basis to the flush. Rehydration in the presence of inhibitors indicated that there were approximately equal contributions from biochemical (outside membranes) and organismal (inside membranes) sources within the first 24 h after rewetting. This suggests that some of the flux was derived from microbial respiration, whilst the remainder was a consequence of enzyme activity, possibly through remnant respiratory pathways in the debris of dead cells.

AB - Synthetic scheme for the preparation of a number of different derivatives of anticancer natural product Psoralidin is described. A convergent synthetic approach is followed using simple starting materials like substituted phenyl acetic esters and benzoic acids. The developed synthetic route leads us to complete the first synthesis of an analogous natural product Lespeflorin I1, a mild melanin synthesis inhibitor. Preliminary bioactivity studies of the synthesized compounds are carried out against two commonly used prostate cancer cell lines. Results show that the bioactivity of the compounds can be manipulated by the simple modification of the functional groups.

AB - ABSTRACT: Whilst survival rates for childhood cancers are excellent, it is known that these patients have an increased risk of death from disease recurrence and other causes. We investigate patterns, trends and survival of cancers in children and young adults in N. Ireland. MATERIALS AND METHODS: 21 years (1993-2013) of cancer incidence data including non-malignant brain tumours from the N. Ireland Cancer Registry for persons aged 0-24 years was analysed using Joinpoint regresssion for trend and the Kaplan Meier method for survival analysis up to end 2013 with excess mortality calculated at one and five years after first cancer diagnosis using standardised mortality ratios. RESULTS: 2633 children and young people were diagnosed with cancer, 1386 (52.6%) male and 1247 female with 1139 (43.3%) aged 0-14. While trends increased over time they did not reach statistical significance except in the 15-24 age group for males and females combined. The most common cancers for age 0-14 were brain, eye and central nervous system and leukaemia with skin (including non-melanoma skin) the most common in the 15-24 age group. 59 patients (2.2%) had a record of a second cancer. Survival was high at 90.7% after 1 year, better among females and similar for older and younger groups. Although mortality in children is low overall, there was an excess mortality 24.7% (22-27.5) p<0.001 at one year and 7.3% (5.5 9.2) p<0.001 for those who survived 5 years. Excluding the primary cancer there was an excess mortality for one year survivors, with deaths twice that of the background level (SMR= 2.2 (1.3-3.0)p=0.005 and although one and a half times background levels at 5 years, the excess mortality was not significant 1.5 (0.6 2.3 p=0.269). CONCLUSION: Whilst survival from childhood cancers is excellent, this work in common with larger studies, highlights the need for ongoing monitoring of cancer survivors. Preventable skin cancer was identified as a problem in young adults. PMID- 27698518 TI - Pruritus: an overview. What drives people to scratch an itch? AB - Pruritus is a common complaint associated with many conditions. It negatively impacts sleep, quality of life, and mortality. Itch is transmitted along both histaminergic and non-histaminergic pathways with a complex interplay between keratinocytes, immune cells and cutaneous neurons. Individuals who present with pruritus should undergo a thorough assessment, especially those over 65 years old, to exclude underlying malignancy. Treatment no longer consists of antihistamines alone. Physicians now have an array of therapies in their armamentarium, to help alleviate this distressing symptom. PMID- 27698519 TI - Uterotonics for Non-emergent Caesarean Section: Protocol Change During UK Licensed Drug Shortage. AB - The aim was to assess the efficacy of Syntometrine (r) (500 micrograms ergometrine with 5 units oxytocin) as an appropriate alternative first-line uterotonic for use in elective caesarean section (CS) during a national shortage of UK-licensed IV oxytocin from April-June 2014. An observational study was performed involving 2 groups of 22 women undergoing elective CS in a UK DGH during this period. Primary endpoints included mean estimated blood loss (EBL), haemoglobin drop post-operatively and transfusion requirement. Secondary endpoints were use of antiemetics and mean post-operative nausea and vomiting (PONV) score. Results for Syntometrine (r) groups and syntocinon groups respectively: mean EBL (ml) 527.3 vs. 550.0 (p=0.5820), mean haemoglobin drop (g/dL) 0.977 vs. 0.982 (p=0.98), blood transfusion 1/22 vs. 0/22 (p=1). Intra operative antiemetics 20/22 vs. 6/22 (p=<0.001), post-operative antiemetics 2/22 vs. 2/22 (p=1), mean PONV score 11.5 vs. 3.5 (p=0.099). As no significant difference in primary endpoints or PONV scores was observed between regimes, we conclude Syntometrine (r) was a safe first-line haemostatic agent for elective CS during oxytocin shortage.

AB - BACKGROUND: The Regulation and Quality Improvement Authority (RQIA) monitors the administration of electroconvulsive therapy (ECT) in Northern Ireland (NI). As part of their inspection methodology RQIA wished to include feedback from ECT patients. The aim of this report is to summarise the opinions of ECT patients over a 1-year period and to compare their feedback about treatment with the standards of best practice, as defined by the Electroconvulsive Therapy Accreditation Service (ECTAS). METHOD: RQIA was granted permission to use the ECTAS patient questionnaire. The questionnaire was distributed to all the ECT clinics in NI and staff were requested to give them to patients who had received a course of ECT. RESULTS: A total of 42 individuals returned questionnaires, 24 females (57.1%) and 18 (42.9%) males. The response rate was 26%. Almost half of respondents were detained under the Mental Health (Northern Ireland) Order 1986 (n=19, 45.2%), with one third receiving ECT as a day patient (n=14, 33.3%). Respondents reported having detailed information about ECT, with ECTAS standards 4.2 and 4.3 being affirmed in over 80% of cases. Eighty percent of respondents (n=34) believed they benefited from ECT. CONCLUSION: The results are mainly favourable towards ECT. The majority felt they benefited from treatment. PMID- 27698520 TI - Re-Staging Following Long-Course Chemoradiotherapy For Rectal Cancer: Does It Influence Management? AB - BACKGROUND: In patients with locally advanced or low rectal cancers, long-course chemoradiotherapy (LCCRT) is recommended prior to surgical management.1 The need for restaging afterwards has been questioned as it may be difficult to interpret imaging due to local tissue effects of chemoradiotherapy. The purpose of this study was to determine if restaging affected the management of patients receiving long-course chemoradiotherapy for rectal cancer. METHODS: A retrospective review of patients with rectal cancer discussed at the South Eastern Health and Social Care Trust Lower Gastrointestinal Multi-Disciplinary Team Meeting (LGIMDT) in 2013 who had received long-course chemoradiotherapy was performed. Patients were identified from the Trust Audit Department, LGIMDT notes and patient records. Imaging results and outcomes from meetings were obtained through the Northern Ireland Picture Archiving and Communications System(r) (NIPACS) and Electronic Care Record(r) (ECR). Data including patient demographics, initial radiological staging and LGIMDT discussion, restaging modality and result, outcome from post treatment LGIMDT discussion and recorded changes in management plans were documented using a proforma. RESULTS: Seventy-one patients with rectal cancer were identified as having LCCRT in 2013 (M:F 36:35; age range 31 - 85 years). Fifty-nine patients were restaged following long-course treatment with computed tomography (CT) and magnetic resonance imaging (MRI). Twelve patients did not undergo restaging. Data was not available for 6 patients, one patient underwent emergency surgery, two patients were not fit for treatment, one failed to attend for restaging and two patients died prior to completion of treatment. Of the 59 patients restaged, 19 patients (32%) had their management plan altered from that which had been proposed at the initial LGIMDT discussion. The most common change in plan was not to operate. Ten patients had a complete clinical and radiological response to treatment and have undergone intensive follow-up. Nine patients had disease progression, with 3 requiring palliative surgery and 6 referred for palliative care. CONCLUSION: Of those patients who were restaged, 32% had their management plan altered from that recorded at the initial LGIMDT discussion. Seventeen per cent of patients in this group had a complete clinical and radiological response to treatment. Fifteen percent demonstrated disease progression. We recommend, therefore, that patients with rectal cancer be restaged with CT and MRI following long-course chemoradiotherapy as surgery may be avoided in up to 27% of cases. PMID- 27698522 TI - Systemic Therapy In Acquired Haemophilia - A Single Institute Experience. AB - A cornerstone of the management of Acquired Haemophilia A (AHA) involves inhibitor eradication. First line immunosuppressive agents are usually steroids, either alone or in combination with cyclophosphamide. We present the use of Rituximab, cyclophosphamide, vincristine and prednisolone (RCVP) combination as immunosuppressant in AHA in a small cohort of patients in order to control their symptoms and eradicate inhibitors. This was a retrospective analysis of all AHA patients treated at the Northern Ireland Haemophilia centre over a six year period. During this time, a total of six patients were newly diagnosed with AHA. Four of these patients failed to respond conventional therapy of steroids and cyclophosphamide, they were however successfully treated with RCVP/ RCV. All patients achieved complete remission with this regimen after 1 to 2 cycles of treatment. Remission has been maintained for an extended time period (range 33-69 months). As AHA is related to immune modulation and, in some cases, underlying malignancy we decided to use this regime as it is effective in either condition. From our experience, we demonstrate that RCVP combination is a promising treatment in patients with AHA who fail to respond to steroids alone or who have been on pre-existing immunosuppression.

AB - This paper aims to examine the dynamics of land transactions, machine investments, and the demand for machine services using farm panel data from China. Recently, China's agriculture has experienced a large expansion of machine rentals and machine services provided by specialized agents, which has contributed to mechanization of agricultural production. On the other hand, the empirical results show that an increase in non-agricultural wage rates leads to expansion of self-cultivated land size. A rise in the proportion of non agricultural income or the migration rate also increases the size of self cultivated land. Interestingly, however, relatively educated farm households decrease the size of self-cultivated land, which suggests that relatively less educated farmers tend to specialize in farming. The demand for machine services has also increased if agricultural wage and migration rate increased over time, especially among relatively large farms. The results on crop income also support complementarities between rented-in land and machine services (demanded), which implies that scale economies are arising in Chinese agriculture with mechanization and active land rental markets. PMID- 27698529 TI - Theory-based metrological traceability in education: A reading measurement network. AB - Huge resources are invested in metrology and standards in the natural sciences, engineering, and across a wide range of commercial technologies. Significant positive returns of human, social, environmental, and economic value on these investments have been sustained for decades. Proven methods for calibrating test and survey instruments in linear units are readily available, as are data- and theory-based methods for equating those instruments to a shared unit. Using these methods, metrological traceability is obtained in a variety of commercially available elementary and secondary English and Spanish language reading education programs in the U.S., Canada, Mexico, and Australia. Given established historical patterns, widespread routine reproduction of predicted text-based and instructional effects expressed in a common language and shared frame of reference may lead to significant developments in theory and practice. Opportunities for systematic implementations of teacher-driven lean thinking and continuous quality improvement methods may be of particular interest and value. PMID- 27698531 TI - Shoot traits and their relevance in terminal drought tolerance of chickpea (Cicer arietinum L.). AB - Chickpea is the second most important legume crop largely grown under semi-arid tropics where terminal drought is one of the major constraints for its productivity. A trait-based selection had been considered more beneficial in drought tolerance breeding to overcome the environmental influence on drought yields. Large number of traits had been suggested in literature, with less indication on their importance and priority, for use in such breeding programs resulting in poor utilization of critical traits in drought tolerance breeding. To identify the most critical traits that contribute to grain yield under drought, 12 chickpea genotypes, with well-defined drought response, were field evaluated by sampling at regular intervals during the cropping period. Large range of variation was observed for shoot biomass productivity, specific leaf area (SLA) and leaf area index (LAI) at different days after sowings (DAS), canopy temperature depression (CTD) at mid-reproductive stages, growth duration and both morphological and analytical yield components. Grain yield under drought was closely associated with the rate of partitioning (p), crop growth rate (C), CTD, phenology, LAI at mid-pod fill stage, pod number m-2 at maturity, shoot biomass at reproductive growth stages and SLA at physiological maturity. The shoot trait(s) were prioritized based on their significance and contribution to drought tolerance. The trait(s) that conferred tolerance varied across genotypes. The order of traits/plant functions identified as important and critical for the drought tolerance were p, C, CTD, growth duration and other related traits. Relatively less important traits were LAI, SLA at the mid reproductive stage and pod number per unit area at maturity. The traits Dr, seeds pod-1 and 100-seed weight were found to be least important. Breeding for the best combination of p and C with the right phenology was proposed to be the best selection strategy to enhance terminal drought tolerance in chickpea. PMID- 27698532 TI - Evaluation of the effects of mulch on optimum sowing date and irrigation management of zero till wheat in central Punjab, India using APSIM. AB - Machinery for sowing wheat directly into rice residues has become more common in the rice-wheat systems of the north-west Indo-Gangetic Plains of South Asia, with increasing numbers of farmers now potentially able to access the benefits of residue retention. However, surface residue retention affects soil water and temperature dynamics, thus the optimum sowing date and irrigation management for a mulched crop may vary from those of a traditional non-mulched crop. Furthermore, the effects of sowing date and irrigation management are likely to vary with soil type and seasonal conditions. Therefore, a simulation study was conducted using the APSIM model and 40 years of weather data to evaluate the effects of mulch, sowing date and irrigation management and their interactions on wheat grain yield, irrigation requirement (I) and water productivity with respect to irrigation (WPI) and evapotranspiration (WPET). The results suggest that the optimum wheat sowing date in central Punjab depends on both soil type and the presence or absence of mulch. On the sandy loam, with irrigation scheduled at 50% soil water deficit (SWD), the optimum sowing date was late October to early November for maximising yield, WPI and WPET. On the clay loam, the optimum date was about one week later. The effect of mulch on yield varied with seasonal conditions and sowing date. With irrigation at 50% SWD, mulching of wheat sown at the optimum time increased average yield by up to 0.5 t ha-1. The beneficial effect of mulch on yield increased to averages of 1.2-1.3 t ha-1 as sowing was advanced to 15 October. With irrigation at 50% SWD and 7 November sowing, mulch reduced the number of irrigations by one in almost 50% of years, a reduction of about 50 mm on the sandy loam and 60 mm on the clay loam. The reduction in irrigation amount was mainly due to reduced soil evaporation. Mulch reduced irrigation requirement by more as sowing was delayed, more so on the sandy loam than the clay loam soil. There was little effect of mulch on irrigation requirement for late October sowings. There were large trade-offs between irrigation input, yield, WPET and WPI on the sandy loam with regard to the optimum irrigation schedule. Maximum yield occurred with very frequent irrigation (10-20% SWD) which also had the greatest irrigation input, while WPI was highest with least frequent irrigation (70% SWD), and WPET was highest with irrigation at 40-50% SWD. This was the case with and without mulch. On the clay loam, the trade offs were not so pronounced, as maximum yield was reached with irrigation at 50% SWD, with and without mulch. However, both WPET and WPI were maximum and irrigation input least at the lowest irrigation frequency (70% SWD). On both soils, maximum yield, WPET and WPI were higher with mulch, while irrigation input was slightly lower, but mulch had very little effect on the irrigation thresholds at which each parameter was maximised. PMID- 27698533 TI - Astaxanthin affects oxidative stress and hyposalivation in aging mice. AB - Oral dryness, a serious problem for the aging Japanese society, is induced by aging-related hyposalivation and causes dysphagia, dysgeusia, inadaptation of dentures, and growth of oral Candida albicans. Oxidative stress clearly plays a role in decreasing saliva secretion and treatment with antioxidants such astaxanthin supplements may be beneficial. Therefore, we evaluated the effects of astaxanthin on the oral saliva secretory function of aging mice. The saliva flow increased in astaxanthin-treated mice 72 weeks after administration while that of the control decreased by half. The plasma d-ROMs values of the control but not astaxanthin-treated group measured before and 72 weeks after treatment increased. The diacron-reactive oxygen metabolites (d-ROMs) value of astaxanthin-treated mice 72 weeks after treatment was significantly lower than that of the control group was. The plasma biological antioxidative potential (BAP) values of the control but not astaxanthin-treated mice before and 72 weeks after treatment decreased. Moreover, the BAP value of the astaxanthin-treated group 72 weeks after treatment was significantly higher than that of the control was. Furthermore, the submandibular glands of astaxanthin-treated mice had fewer inflammatory cells than the control did. Specifically, immunofluorescence revealed a significantly large aquaporin-5 positive cells in astaxanthin-treated mice. Our results suggest that astaxanthin treatment may prevent age-related decreased saliva secretion. PMID- 27698534 TI - Raf kinase inhibitor protein regulates oxygen-glucose deprivation-induced PC12 cells apoptosis through the NF-kappaB and ERK pathways. AB - Raf-1 kinase inhibitory protein (RKIP) is a critical molecule for cellular responses to stimuli. In this study, we investigated whether RKIP is responsible for neural cell apoptosis induced by oxygen-glucose deprivation (OGD) and explored the role of NF-kappaB and ERK pathways regulated by RKIP under OGD stimuli. RKIP was overexpressed or knocked down using lentivirus in PC12 cells, which were then challenged by OGD. RKIP overexpression significantly increased the cell viability of OGD cells, and attenuated apoptosis, cell cycle arrest, and reactive oxygen species generation. RKIP knockdown induced reverse effects. Moreover, we found that RKIP interacted with TAK1, NIK, IKK, and Raf-1 and negatively regulated the NF-kappaB and ERK pathways. RKIP overexpression significantly inhibited IKK, IkappaBalpha, and P65 phosphorylation in NF-kappaB pathway and MEK, ERK, and CREB phosphorylation in ERK pathway, respectively. RKIP knockdown induced reverse effects. Furthermore, a NF-kappaB inhibitor BAY 11-7082 and a MEK inhibitor U0126 blocked the changes caused by RKIP down-regulation after OGD. In conclusion, these results demonstrate that RKIP plays a key role in neural cell apoptosis caused by OGD partly via regulating NF-kappaB and ERK pathways. The present study may provide new insights into the role of RKIP in ischemic stroke. PMID- 27698535 TI - l-Theanine protects against excess dopamine-induced neurotoxicity in the presence of astrocytes. AB - l-Theanine (gamma-glutamylethylamide), a component of green tea, is considered to have regulatory and neuroprotective roles in the brain. The present study was designed to determine the effect of l-theanine on excess dopamine-induced neurotoxicity in both cell culture and animal experiments. The primary cultured mesencephalic neurons or co-cultures of mesencephalic neurons and striatal astrocytes were pretreated with l-theanine for 72 h, and then treated with excess dopamine for further 24 h. The cell viability of dopamine neurons and levels of glutathione were evaluated. Excess dopamine-induced neurotoxicity was significantly attenuated by 72 h preincubation with l-theanine in neuron astrocyte co-cultures but not in neuron-rich cultures. Exposure to l-theanine increased the levels of glutathione in both astrocytes and glial conditioned medium. The glial conditioned medium from l-theanine-pretreated striatal astrocytes attenuated dopamine-induced neurotoxicity and quinoprotein formation in mesencephalic neurons. In addition, replacement of l-glutamate with l-theanine in an in vitro cell-free glutathione-synthesis system produced glutathione-like thiol compounds. Furthermore, l-theanine administration (4 mg/kg, p.o.) for 14 days significantly increased glutathione levels in the striatum of mice. The results suggest that l-theanine provides neuroprotection against oxidative stress induced neuronal damage by humoral molecules released from astrocytes, probably including glutathione. PMID- 27698536 TI - Synergistic antioxidative effect of astaxanthin and tocotrienol by co encapsulated in liposomes. AB - Astaxanthin and vitamin E are both effective antioxidants that are frequently used in cosmetics, as food additives, and in to prevent oxidative damage. A combination of astaxanthin and vitamin E would be expected to show an additive anntioxidative effect. In this study, liposomes co-encapsulating astaxanthin and the vitamin E derivatives alpha-tocopherol (alpha-T) or tocotrienols (T3) were prepared, and the antioxidative activity of these liposomes toward singlet oxygen and hydroxyl radical was evaluated in vitro. Liposomes co-encapsulating astaxanthin and alpha-T showed no additive anntioxidative effect, while the actual scavenging activity of liposomes co-encapsulating astaxanthin and T3 was higher than the calculated additive activity. To clarify why this synergistic effect occurs, the most stable structure of astaxanthin in the presence of alpha T or alpha-T3 was calculated. Only alpha-T3 was predicted to form hydrogen bonding with astaxanthin, and the astaxanthin polyene chain would partially interact with the alpha-T3 triene chain, which could explain why there was a synergistic effect between astaxanthin and T3 but not alpha-T. In conclusion, co encapsulation of astaxanthin and T3 induces synergistic scavenging activity by intermolecular interactions between the two antioxidants. PMID- 27698537 TI - Resveratrol improves salivary dysfunction in a non-obese diabetic (NOD) mouse model of Sjogren's syndrome. AB - Resveratrol is a natural polyphenol produced by plants in response to environmental stress. This compound has been shown to have pharmacological effects against a wide range of diseases including neurological, hepatic, cardiovascular and autoimmune conditions. The non-obese diabetic (NOD) mouse, in which loss of lacrimal and salivary gland function occurs, has been studied as an animal model for Sjogren's syndrome. In this study, we confirmed that administration of resveratrol results in increased secretion of saliva in NOD mice. Although resveratrol enhanced Sirt1 activity, inflammatory cell infiltration was not affected. Moreover, expression of the anti-inflammatory cytokine IL-10 in salivary glands was enhanced in the resveratrol-administered group. Thus, we confirmed a novel therapeutic effect for resveratrol on salivary dysfunction in Sjogren's syndrome. PMID- 27698538 TI - Vitamin A deficiency impacts the structural segregation of gut microbiota in children with persistent diarrhea. AB - To investigate whether gut microbiota is associated with vitamin A nutritional levels in children with persistent diarrhea, a total of 59 pediatric patients with persistent diarrhea aged 1-12 months were selected from the Department of Gastroenterology at the Children's Hospital of Chongqing Medical University, China. Subjects were hospitalized and divided into VA-deficient (n = 30) and VA normal (n = 29) groups according to their venous serum retinol levels. Fecal samples from all 59 subjects were collected immediately after admission and analyzed by Illumina MiSeq for 16S rRNA genes to characterize the overall microbiota of the samples. The gut microbiota of the VA-deficient and VA-normal groups were compared using a bioinformatic statistical approach. The Shannon index (p = 0.02), Simpson index (p = 0.01) and component diagram data indicated significantly lower diversity in the VA-deficient than the VA-normal group. A metagenome analysis (LEfSe) and a differentially abundant features approach using Metastats revealed that Escherichia coli and Clostridium butyricum were the key phylotypes of the VA-normal group, while Enterococcus predominated the VA deficient group. In conclusion, the diversity of gut microbiota and the key phylotypes are significantly different in children with persistent diarrhea at different VA nutritional levels. PMID- 27698539 TI - Energy metabolism and nutritional status in hospitalized patients with lung cancer. AB - This study aimed to investigate the energy metabolism of patients with lung cancer and the relationship between energy metabolism and proinflammatory cytokines. Twenty-eight patients with lung cancer and 18 healthy controls were enrolled in this study. The nutritional status upon admission was analyzed using nutritional screening tools and laboratory tests. The resting energy expenditure and respiratory quotient were measured using indirect calorimetry, and the predicted resting energy expenditure was calculated using the Harris-Benedict equation. Energy expenditure was increased in patients with advanced stage disease, and there were positive correlations between measured resting energy expenditure/body weight and interleukin-6 levels and between measured resting energy expenditure/predicted resting energy expenditure and interleukin-6 levels. There were significant relationships between body mass index and plasma leptin or acylated ghrelin levels. However, the level of appetite controlling hormones did not affect dietary intake. There was a negative correlation between plasma interleukin-6 levels and dietary intake, suggesting that interleukin-6 plays a role in reducing dietary intake. These results indicate that energy expenditure changes significantly with lung cancer stage and that plasma interleukin-6 levels affect energy metabolism and dietary intake. Thus, nutritional management that considers the changes in energy metabolism is important in patients with lung cancer. PMID- 27698540 TI - Influence of regular exercise on gastric emptying in healthy men: a pilot study. AB - Functional gastrointestinal disorders (FGIDs), including functional dyspepsia (FD), are common chronic disorders even in the younger population. Physical activity is advocated for patients with FGIDs, although the evidence is insufficient. We investigated the association between the intensity of regular exercise and gastric emptying to determine the effect of physical activity on dyspeptic symptoms. Thirty healthy individuals were selected and divided into three groups (low, moderate, and high) using the index of total exercise intensity in a week. Gastric emptying was evaluated by the 13C-acetate breath test. Gastroesophageal reflux symptoms, dyspeptic symptoms, stool forms, scores of anxiety and depression, and scores of sleep quality were also compared. Baseline scores of gastroesophageal reflux symptoms, anxiety, depression, and sleep quality were not different among the three groups. Gastric emptying was significantly faster in low-intensity exercise group than the moderate-intensity exercise group. Although the presence of loose stool and alcohol consumption were also associated with the intensity of regular exercise, these variables were not confounders. In conclusion, the intensity of regular exercise was independently associated with gastric emptying in healthy individuals. These baseline data would be useful for consideration of an optimal exercise intervention for the treatment of FD. PMID- 27698541 TI - Effects of isoflavones on lipid and apolipoprotein levels in patients with type 2 diabetes in Heilongjiang Province in China. AB - In this study, we examined the association between soy isoflavones and lipid profiles, apolipoprotein levels in patients with type 2 diabetes in China. The study population was composed of 120 cases (80 women with type 2 diabetes and 40 healthy women). Objects in treatment group received isoflavones 435 mg/day for 2 months, then lipid profiles were analyzed by the colorimetry method and apolipoprotein levels were determined by immune turbidimetric method. And all the indexes were determined after oral glucose tolerance test. The levels of total cholesterol, triglyceride and LDL-C significantly reduced and the levels of HDL-C and apolipoprotein A1 significantly raised in the treatment group after intervention (p<0.05). After oral glucose tolerance test, the level of total cholesterol was lower at postprandial 6 h than at empty stomach in treatment group, it had significantly difference (p<0.05). LDL-C levels in the treatment group not only decreased after intervention, but also was significantly lower at postprandial 4, 6 h than in non-intervention group. The ratio of apolipoprotein A1/apolipoprotein B at postprandial 2 h was the highest after treatment in isoflavone group. Supplementation with 435 mg/day of isoflavones exerted favorable effect on the blood total cholesterol, LDL-C levels and the ratio of apolipoprotein A1/apolipoprotein B in Chinese type 2 diabetes women. PMID- 27698542 TI - Relationship between homeostasis model assessment of insulin resistance and beta cell function and serum 25-hydroxyvitamin D in non-diabetic Korean adults. AB - The purpose of this study is to look at these relationships in non-diabetic Korean adults. This study was based on data from the KNHANES V-1, which is representative of the population of Korea. A total of 5,492 participants (>=20 years in age) without type 1 or type 2 diabetes, assessed for serum 25 hydroxyvitamin D [25(OH)D], fasting blood glucose and insulin, as well as anthropometric variables, were included in the analyses. The key study results were as follows: First, vitamin D status [vitamin D deficient, 25(OH)D <25 nM; vitamin D insufficient, 25(OH)D >=25, <50 nM; vitamin D sufficient, 25(OH)D >=50 nM] was inversely associated with homeostasis model assessment of insulin resistance (HOMA-IR) and beta cell function (HOMA-B) in model 2 (adjusted for age and gender) and 3 (further adjusted for smoking, alcohol drinking, regular exercise, systolic and diastolic blood pressure, waist circumference, and body mass index). Second, in model 4, when further adjusted for total cholesterol, triglycerides, and HDL-C, vitamin D status was inversely associated with HOMA-B. However, association of vitamin D status and HOMA-IR was no longer significant. In conclusion, vitamin D was inversely associated with beta cell function in non diabetic Korean adults but was not associated with insulin resistance. PMID- 27698543 TI - Analysis of negative result in serum anti-H. pylori IgG antibody test in cases with gastric mucosal atrophy. AB - The purpose is to elucidate factors related to negative results of anti-H. pylori antibody test in cases with gastric mucosal atrophy. A total of 859 individuals without past history of eradication therapy for H. pylori (545 males, 314 females; mean age 52.4 years) who underwent an upper GI endoscopy examination and serological test were enrolled as subjects. Serological testing was performed using SphereLight H. pylori antibody J(r), and endoscopic findings of gastric mucosal atrophy by the classification of Kimura and Takemoto and post-eradication findings were analyzed. The positive rates for the anti-H. pylori antibody test in subjects with and without gastric mucosal atrophy were 85.6% and 0.9%, respectively. In analysis of subjects with gastric mucosal atrophy, a low positive rate and serum titer was observed in subjects with C1, C2 and O3 atrophy. When the analysis was performed separately in male and female subjects, low positive rate was observed in males with O3 atrophy and females with C2 atrophy. Suspected post-eradication endoscopic findings were more frequently observed in cases with C2 atrophy. In conclusion, negative result of anti-H. pylori antibody test was frequently observed in middle-aged subjects with C1, C2 and O3 gastric mucosal atrophy. PMID- 27698544 TI - Esomeprazole- or rabeprazole-based triple therapy eradicated Helicobacter pylori comparably regardless of clarithromycin susceptibility and CYP2C19 genotypes. AB - The aim of this study was to assess the efficacy of esomeprazole-based triple therapy compared with rabeprazole-based triple therapy according to CYP2C19 genotype and clarithromycin susceptibility status for first-line eradication therapy of Helicobacter pylori (H. pylori) in Japan. We enrolled 219 H. pylori infected patients, and randomly allocated patients to the EAC group (esomeprazole 20 mg, clarithromycin 200 mg, amoxicillin 750 mg for one week, with all drugs given twice daily) or RAC group (rabeprazole 10 mg, clarithromycin 200 mg, amoxicillin 750 mg for one week, with all drugs given twice daily). The H. pylori eradication rate according to the PP analyses was 75.0% (95% CI: 65.2-82.8%) in the EAC group and 71.4% (95% CI: 61.4-79.1%) in the RAC group. There were no statistically significant differences. The eradication rates of the clarithromycin-resistant/-sensitive strains were, respectively, 45.0% (95% CI: 30.7-60.2%)/98.0% (95% CI: 88.7-100%) in the EAC group and 39.5% (95% CI: 25.6 55.3%)/93.5% (95% CI: 81.9-98.4%) in the RAC group. The eradication rate of the clarithromycin-sensitive strains was significantly higher than that of the resistant strains in both groups. In conclusion, EAC and RAC therapies show a comparable efficacy regardless of the CYP2C19 genotype and clarithromycin susceptibility status in Japan. PMID- 27698546 TI - Insights from lncRNAs Profiling of MIN6 Beta Cells Undergoing Inflammation. AB - Type 1 diabetes mellitus (T1DM) is an organ-specific autoimmune disease characterized by chronic and progressive apoptotic destruction of pancreatic beta cells. During the initial phases of T1DM, cytokines and other inflammatory mediators released by immune cells progressively infiltrate islet cells, induce alterations in gene expression, provoke functional impairment, and ultimately lead to apoptosis. Long noncoding RNAs (lncRNAs) are a new important class of pervasive genes that have a variety of biological functions and play key roles in many diseases. However, whether they have a function in cytokine-induced beta cell apoptosis is still uncertain. In this study, lncRNA microarray technology was used to identify the differently expressed lncRNAs and mRNAs in MIN6 cells exposed to proinflammatory cytokines. Four hundred forty-four upregulated and 279 downregulated lncRNAs were detected with a set filter fold-change ?2.0. To elucidate the potential functions of these lncRNAs, Gene Ontology (GO) and pathway analyses were used to evaluate the potential functions of differentially expressed lncRNAs. Additionally, a lncRNA-mRNA coexpression network was constructed to predict the interactions between the most strikingly regulated lncRNAs and mRNAs. This study may be utilized as a background or reference resource for future functional studies on lncRNAs related to the diagnosis and development of new therapies for T1DM. PMID- 27698545 TI - Protective Effect of Galectin-1 during Histoplasma capsulatum Infection Is Associated with Prostaglandin E2 and Nitric Oxide Modulation. AB - Histoplasma capsulatum is a dimorphic fungus that develops a yeast-like morphology in host's tissue, responsible for the pulmonary disease histoplasmosis. The recent increase in the incidence of histoplasmosis in immunocompromised patients highlights the need of understanding immunological controls of fungal infections. Here, we describe our discovery of the role of endogenous galectin-1 (Gal-1) in the immune pathophysiology of experimental histoplasmosis. All infected wild-type (WT) mice survived while only 1/3 of Lgals1-/- mice genetically deficient in Gal-1 survived 30 days after infection. Although infected Lgals1-/- mice had increased proinflammatory cytokines, nitric oxide (NO), and elevations in neutrophil pulmonary infiltration, they presented higher fungal load in lungs and spleen. Infected lung and infected macrophages from Lgals1-/- mice exhibited elevated levels of prostaglandin E2 (PGE2, a prostanoid regulator of macrophage activation) and prostaglandin E synthase 2 (Ptgs2) mRNA. Gal-1 did not bind to cell surface of yeast phase of H. capsulatum, in vitro, suggesting that Gal-1 contributed to phagocytes response to infection rather than directly killing the yeast. The data provides the first demonstration of endogenous Gal-1 in the protective immune response against H. capsulatum associated with NO and PGE2 as an important lipid mediator in the pathogenesis of histoplasmosis. PMID- 27698547 TI - Chronic hip dislocations: a rarity. How should we treat them? AB - BACKGROUND: Chronically dislocated hips (>6 weeks) are usually the consequence of difficulties accessing appropriate healthcare in a timely fashion after dislocation; this explains why they are more common in developing countries. Due to a lack of research, there is currently no consensus on the best treatment available for patients presenting with this condition. Therefore, it is important to assess the treatments available so as to ensure that doctors adequately manage those presenting with this debilitating condition in the future. OBJECTIVE: To identify the best treatment strategy for chronic hip dislocations based on the treatment outcomes achieved by a free surgical clinic in Phnom Penh, Cambodia. PATIENTS AND METHOD: A retrospective analysis of the surgical centre's electronic records was conducted. Patients presenting with hips dislocated for >6 weeks were included whilst congenitally dislocated hips were excluded. Treatment outcomes, based on follow up notes, were then assessed. Data abstracted during chart review was analysed using descriptive and comparative statistics. RESULTS: 72 patients presented to the clinic with chronic hip dislocations. 42 patients received recorded treatment and 32 were followed up. Among patients with follow-up, 63% experienced 'good' outcomes after treatment. Open reductions, the most common treatment, were successful 65% of the time. The use of preoperative traction increased the success of open reductions by 13%, however, this result was not statistically significant (p = 0.64). CONCLUSION: Open reductions with pre operative traction seem to be an acceptable treatment in this setting. PMID- 27698549 TI - Factors Associated with HIV Discussion and Condom Use with Sexual Partners in an Underserved Community in South Africa. AB - We examined factors associated with discussing HIV and condom use with a sexual partner. Two cross-sectional surveys were conducted in 2004 prior to the implementation of an HIV awareness campaign in a South African community and in 2008 after a three-year education program. Overall, the proportion of individuals who had discussed HIV with a sexual partner increased from 76% in 2004 to 89% in 2008 (p < .001). Among respondents who had sex six months before completing the surveys, condom use significantly increased from 64% in 2004 to 79% in 2008 (p < .05). Respondents who discussed HIV with a sexual partner were more likely to use condoms than respondents who had not discussed HIV with a sexual partner (OR=2.08, 95% CI=1.16, 3.72). These findings indicate the importance of interventions aimed at promoting HIV awareness and discussion of HIV in communities with individuals at risk of acquiring HIV. PMID- 27698550 TI - Intravitreal methotrexate infusion for proliferative vitreoretinopathy. AB - PURPOSE: The purpose of this study was to evaluate intravitreal methotrexate infusion (IMI) during pars plana vitrectomy (PPV) for retinal detachment in patients with high risk for the development of proliferative vitreoretinopathy (PVR). METHODS: Patients presenting with severe recurrent PVR with tractional retinal detachment and/or a history of severe ocular inflammation were treated with IMI. Clinical outcomes were determined from a retrospective medical chart review. RESULTS: Twenty-nine eyes presenting with either tractional retinal detachment and recurrent PVR (n=22) or a history of severe inflammation associated with high PVR risk (n=7) received IMI during PPV. Best-corrected visual acuity at 6 months was >=20/200 in 19 of 29 eyes (66%) and remained stable or improved compared with initial presentation in 24 of 29 eyes (83%). At the last follow-up examination, the retinas of 26 of 29 eyes (90%) remained attached after IMI while three eyes required another reattachment procedure. Three additional eyes (10%) developed recurrent limited PVR without recurrent RD and were observed. No complications attributable to IMI occurred during a mean follow up of 27 months. CONCLUSION: Eyes at high risk for PVR development due to a history of prior PVR or intraocular inflammation had a low incidence of PVR following IMI at the time of PPV for RD repair. No significant safety issues from IMI were observed in this series. PMID- 27698551 TI - Short wave-automated perimetry (SWAP) versus optical coherence tomography in early detection of glaucoma. AB - OBJECTIVE: To assess the role and diagnostic effectiveness of optical coherence tomography (OCT) and short wave-automated perimetry (SWAP) to distinguish between normal, glaucoma suspects, and surely diagnosed glaucomatous eye. BACKGROUND: Changes in the optic disc and retinal nerve fiber layer (RNFL) often precede the appearance of visual field defect with standard automated perimetry. Unfortunately, RNFL defect can be difficult to identify during clinical examination. Early detection of glaucoma is still controversial, whether by OCT, SWAP, or frequency-doubling technology perimetry. PATIENTS AND METHODS: In this randomized controlled, consecutive, prospective study, a total 70 subjects (140 eyes) were included in the study, divided into three groups: Group A, 10 healthy volunteers (20 eyes); Group B, 30 patients (60 eyes) with glaucoma suspect; and Group C, 30 patients (60 eyes) with already diagnosed glaucomatous eyes. RESULTS: Average RNFL thickness was 75+/-9.0 in the glaucoma group, 99+/-15.5 in the control group, and 94+/-12 in glaucoma suspect. The inferior quadrant was the early parameter affected. There was significant correlation between visual field parameters and RNFL thickness in both glaucoma and glaucoma suspect groups. CONCLUSION: Both RNFL thickness measured by OCT and SWAP indices are good discrimination tools between glaucomatous, glaucoma suspect, and normal eyes. OCT parameters tend to be more sensitive than SWAP parameters. PMID- 27698548 TI - Bio-Adaption between Magnesium Alloy Stent and the Blood Vessel: A Review. AB - Biodegradable magnesium (Mg) alloy stents are the most promising next generation of bio-absorbable stents. In this article, we summarized the progresses on the in vitro studies, animal testing and clinical trials of biodegradable Mg alloy stents in the past decades. These exciting findings led us to propose the importance of the concept "bio-adaption" between the Mg alloy stent and the local tissue microenvironment after implantation. The healing responses of stented blood vessel can be generally described in three overlapping phases: inflammation, granulation and remodeling. The ideal bio-adaption of the Mg alloy stent, once implanted into the blood vessel, needs to be a reasonable function of the time and the space/dimension. First, a very slow degeneration of mechanical support is expected in the initial four months in order to provide sufficient mechanical support to the injured vessels. Although it is still arguable whether full mechanical support in stented lesions is mandatory during the first four months after implantation, it would certainly be a safety design parameter and a benchmark for regulatory evaluations based on the fact that there is insufficient human in vivo data available, especially the vessel wall mechanical properties during the healing/remodeling phase. Second, once the Mg alloy stent being degraded, the void space will be filled by the regenerated blood vessel tissues. The degradation of the Mg alloy stent should be 100% completed with no residues, and the degradation products (e.g., ions and hydrogen) will be helpful for the tissue reconstruction of the blood vessel. Toward this target, some future research perspectives are also discussed. PMID- 27698552 TI - Profile of adalimumab and its potential in the treatment of uveitis. AB - Uveitis refers to the presence of intraocular inflammation, and as a strict definition compromises the iris and ciliary body anteriorly and the choroid posteriorly (the uvea). Untreated, uveitis can lead to visual loss or blindness. The etiology of uveitis can include both infectious and noninfectious (usually immune-mediated) causes, the latter of which are often mediated predominantly by Th1 CD4+ T-cells that secrete proinflammatory cytokines. Tumor necrosis factor alpha (TNF-alpha) is a proinflammatory cytokine involved in the pathogenesis of uveitis, which at high concentrations can cause excess inflammation and tissue damage. Adalimumab is a recombinant human IgG1 monoclonal antibody specific for human TNF-alpha. Historically, corticosteroids and methotrexate were used to treat uveitis; however, newer biologic agents such as adalimumab have revolutionized therapy for noninfectious uveitis. Adalimumab has shown efficacy in treating refractory uveitis in multiple settings, including idiopathic disease, juvenile idiopathic arthritis, sarcoidosis, Behcets disease, and uveitis secondary to spondyloarthropathies, among several other noninfectious uveitis conditions. In this paper, we will review the profile of adalimumab, the role of TNF-alpha in uveitis, discuss safety data, and summarize key articles evaluating the efficacy of adalimumab in treating uveitis secondary to the most commonly associated autoimmune diseases. PMID- 27698554 TI - A qualitative investigation of barriers and facilitators of rehabilitation success from the psychosomatic inpatients' perspective. AB - OBJECTIVE: Psychosomatic inpatient rehabilitation aims at promoting functioning in patients with mental disorders. Although generally effective, some patients do not benefit from this rehabilitation and suffer from symptoms as well as functional impairment. This study aimed to identify patient-reported factors influencing activity and participation outcomes. SUBJECT AND METHODS: Five focus groups with N=23 former psychosomatic rehabilitation inpatients were conducted. The discussions focused on facilitators and barriers of treatment outcome. The material was analyzed inductively according to qualitative content analysis. Categories were derived from the material. RESULTS: Patients reported sociodemographic and clinical characteristics as well as personal factors, preparation before psychotherapy, and aspects of employment and health care as predictors of treatment success. CONCLUSION: A wide range of possible factors that influence the course of functioning from the patients' perspective were determined. These factors can be assigned to the ICF conceptual model. Clinician and researcher perspectives may complement these factors. PMID- 27698553 TI - Professionals' perception on the management of patients with dual disorders. AB - BACKGROUND: There is a need to evaluate the professionals' perception about the consequences of the lack of therapeutic adherence in the evolution of patients with co-occurring disorders. METHODS: An online survey, released on the Socidrogalcohol [Spanish Scientific Society for Research on Alcohol, Alcoholism and other Drug Addictions] and Sociedad Espanola de Patologia Dual [the Spanish Society of Dual Pathology] web pages, was answered by 250 professionals who work in different types of Spanish health centers where dual diagnosis patients are assisted. RESULTS: Most professionals perceived the existence of noncompliance among dual diagnosis patients. Almost all of these professionals (99%) perceived that noncompliance leads to a worsening of the progression of the patient's disorder, in both the exacerbation of mental disorders and the consumption of addictive substances. Most of the professionals (69.2%) considered therapeutic alliance as the main aspect to take into account to improve the prognosis in this population. The primary purpose of treatment must be the improvement of psychotic phase positive symptoms, followed by the control of behavior disorders, reduction of craving, improvement of social and personal performances, and reduction of psychotic-phase negative symptoms. CONCLUSION: Most professionals perceived low adherence among dual diagnosis patients. This lack of adherence is associated with a worsening of their disease evolution, which is reflected in exacerbations of the psychopathology and relapse in substance use. Therefore, we propose to identify strategies to improve adherence. PMID- 27698555 TI - Efficacy and safety of Chinese herbal medicine for chronic prostatitis associated with damp-heat and blood-stasis syndromes: a meta-analysis and literature review. AB - OBJECTIVE: The aim of this meta-analysis and systematic review is to evaluate the safety and efficacy of Chinese herbal medicine (CHM) for chronic prostatitis (CP) associated with damp-heat and blood-stasis syndromes. METHODS: An electronic search of 13 databases up to May 2016 was screened to identify randomized controlled trials comparing the safety and efficacy of CHM for the treatment of CP associated with damp-heat and blood-stasis syndromes. Studies reporting on effective rates, adverse events, National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) scores, and symptom index of Chinese medicine for chronic prostatitis (SI-CM) scores as outcomes were included in the analysis. Data were analyzed by fixed- or random-effect models using the Review Manager software. RESULTS: Thirteen articles with the modified Jadad score >=4 were identified. It was found that CHM was superior to placebo in increasing the efficacy (odds ratio: 6.72, 95% confidence interval [CI]: 2.78-9.48, P<0.00001) and reducing the SI-CM scores (standardized mean difference: -1.08, 95% CI: -1.35 to -0.81, P<0.00001). Oral CHMs were significantly more effective than placebo at reducing NIH-CPSI scores, with a mean difference of -1.39 (95% CI: -1.87 to 0.92, P<0.00001). Nevertheless, no significant differences were found between Prostant and placebo (standardized mean difference: -0.23, 95% CI: -0.46 to 0.01, P=0.06). The frequency of adverse events associated with oral CHM was similar to that associated with placebo (risk ratio: 1.36, 95% CI: 0.72-2.55, P=0.34) and less than that associated with Prostant (risk ratio: 1.63, 95% CI: 1.14-2.34, P=0.008). CONCLUSION: Our novel analysis demonstrates that CHM ranks highest in terms of improvement of CP associated with damp-heat and blood-stasis syndromes. While Prostant showed some efficacy in this disorder, it was associated with a smaller reduction in NIH-CPSI scores. In conclusion, CHM monotherapy is safe and effective for the treatment of CP associated with damp-heat and blood-stasis syndromes. PMID- 27698556 TI - Digital life storybooks for people with dementia living in care homes: an evaluation. AB - BACKGROUND AND AIM: There is increasing interest in using information and communication technology to help older adults with dementia to engage in reminiscence work. Now, the feasibility of such approaches is beginning to be established. The purpose of this study was to establish an evidence-base for the acceptability and efficacy of using multimedia digital life storybooks with people with dementia in care homes, in comparison with conventional life storybooks, taking into account the perspectives of people with dementia, their relatives, and care staff. METHODS: Participatory design was used to create a life story movie based on a previously completed conventional life storybook with six older adults with dementia (four females; mean age 82 years). Relatives were involved in helping the participant to provide additional information and materials for the digital life storybook. In this multiple case study design, both quantitative and qualitative approaches were used. For quantitative purposes, a set of questionnaires that had been completed three times before and after the conventional life storybook was developed were repeated 4 weeks after the life story movie was completed. Semistructured interview questions were designed to collect feedback from participants, relatives, and care staff. RESULTS: The result indicated that five of the six participants showed additional improvement in measures of quality of life and autobiographical memory. All participants showed improvement or stability in depression scores. Thematic analysis showed that, participants, relatives, and care home staff viewed digital life storybooks as a very useful tool triggering memories and (largely) positive emotions. Participants' case vignettes were presented to document the impact of digital life storybook. PMID- 27698557 TI - Tai chi qigong as a means to improve night-time sleep quality among older adults with cognitive impairment: a pilot randomized controlled trial. AB - PURPOSE: Age-related cognitivee decline is a growing public health concern worldwide. More than a quarter of adults with cognitive impairment experience sleep disturbance. The objective of this pilot study was to evaluate the preliminary effects of tai chi qigong (TCQ) on improving the night-time sleep quality of older adults with cognitive impairment. PARTICIPANTS: Older adults with cognitive impairment who complain of sleep disturbance. METHODS: A randomized controlled trial with two groups. Fifty-two subjects were recruited from two district elderly community centers and randomly assigned to either the TCQ group (n=27) or the control group (n=25). The intervention group received TCQ training consisting of two 60-minute sessions each week for 2 months. The control group was advised to maintain their usual activities. Sleep quality was measured by the Chinese Pittsburgh Sleep Quality Index. Quality of life was measured by Short-form 12, cognitive functions measured by mini-mental state examination, and subjective memory deficits measured by the memory inventory for Chinese. RESULTS: Data were collected at baseline, 2 months, and 6 months. Significant results were noted at 6 months in the Chinese Pittsburgh Sleep Quality Index global score (P=0.004), sleep duration (P=0.003), habitual sleep efficiency (P=0.002), and the Short-form 12 mental health component (P<0.001). The TCQ participants reported better sleep quality and a better (quality of life) mental health component than the control group. CONCLUSION: TCQ can be considered a useful nonpharmacological approach for improving sleep quality in older adults with cognitive impairment. CLINICAL TRIAL REGISTRATION: CUHK_CCT00448 (https://www2.ccrb.cuhk.edu.hk/registry/public/287). PMID- 27698559 TI - Efficacy and safety of tamsulosin hydrochloride 0.2 mg and combination of tamsulosin hydrochloride 0.2 mg plus solifenacin succinate 5 mg after transurethral resection of the prostate: a prospective, randomized controlled trial. AB - OBJECTIVE: The objective of this study was to evaluate the safety and efficacy of tamsulosin hydrochloride 0.2 mg (TAM) and its combination with solifenacin succinate 5 mg (SOL) after transurethral resection of the prostate (TURP). PATIENTS AND METHODS: The patients were randomized into three groups: TURP (group 1), TURP plus TAM (group 2), and TURP plus TAM + SOL (group 3). Patients in group 2 and group 3 received medication for 4 weeks. The primary efficacy end points were the mean change in total International Prostate Symptom Score (IPSS) and IPSS subscores. The secondary end points included quality-of-life score, Overactive Bladder Symptom Score, and short-form voiding and storage score of International Continence Society. RESULTS: In total, 37 men (31.8%) in group 1, 37 men (31.8%) in group 2, and 42 men (36.2%) in group 3 completed the study. In total IPSS, no significant improvement was seen from baseline to the end of treatment in groups 2 and 3 compared with group 1. However, in group 2, the decrement in the IPSS storage score was smaller than group 1 (P=0.02), and in group 3, the decrement in the IPSS voiding score was smaller than group 1 (P=0.05). In groups 2 and 3 compared with group 1, improvements in the quality of life score, total score of Overactive Bladder Symptom Score, and short-form voiding score and storage score of International Continence Society were not statistically significant. CONCLUSION: Treatment with TAM and combination of TAM and SOL did not have significant additional benefits for lower urinary tract symptoms during the early recovery period after TURP. PMID- 27698558 TI - Effects of combined physical and cognitive training on fitness and neuropsychological outcomes in healthy older adults. AB - PURPOSE: Physical exercise and cognitive training have been shown to enhance cognition among older adults. However, few studies have looked at the potential synergetic effects of combining physical and cognitive training in a single study. Prior trials on combined training have led to interesting yet equivocal results. The aim of this study was to examine the effects of combined physical and cognitive interventions on physical fitness and neuropsychological performance in healthy older adults. METHODS: Seventy-six participants were randomly assigned to one of four training combinations using a 2*2 factorial design. The physical intervention was a mixed aerobic and resistance training program, and the cognitive intervention was a dual-task (DT) training program. Stretching and toning exercises and computer lessons were used as active control conditions. Physical and cognitive measures were collected pre- and postintervention. RESULTS: All groups showed equivalent improvements in measures of functional mobility. The aerobic-strength condition led to larger effect size in lower body strength, independently of cognitive training. All groups showed improved speed of processing and inhibition abilities, but only participants who took part in the DT training, independently of physical training, showed increased task-switching abilities. The level of functional mobility after intervention was significantly associated with task-switching abilities. CONCLUSION: Combined training did not yield synergetic effects. However, DT training did lead to transfer effects on executive performance in neuropsychological tests. Both aerobic-resistance training and stretching-toning exercises can improve functional mobility in older adults. PMID- 27698560 TI - The effect of domiciliary noninvasive ventilation on clinical outcomes in stable and recently hospitalized patients with COPD: a systematic review and meta analysis. AB - INTRODUCTION: Noninvasive ventilation (NIV) improves survival among patients with hypercapnic respiratory failure in hospital, but evidence for its use in domiciliary settings is limited. A patient's underlying risk of having an exacerbation may affect any potential benefit that can be gained from domiciliary NIV. This is the first comprehensive systematic review to stratify patients based on a proxy for exacerbation risk: patients in a stable state and those immediately post-exacerbation hospitalization. METHODS: A systematic review of nonrandomized and randomized controlled trials (RCTs) was undertaken in order to compare the relative effectiveness of different types of domiciliary NIV and usual care on hospital admissions, mortality, and health-related quality of life. Standard systematic review methods were used for identifying studies (until September 2014), quality appraisal, and synthesis. Data were presented in forest plots and pooled where appropriate using random-effects meta-analysis. RESULTS: Thirty-one studies were included. For stable patients, there was no evidence of a survival benefit from NIV (relative risk [RR] 0.88 [0.55, 1.43], I2=60.4%, n=7 RCTs), but there was a possible trend toward fewer hospitalizations (weighted mean difference -0.46 [-1.02, 0.09], I2=59.2%, n=5 RCTs) and improved health related quality of life. For posthospital patients, survival benefit could not be demonstrated within the three RCTs (RR 0.89 [0.53, 1.49], I2=25.1%), although there was evidence of benefit from four non-RCTs (RR 0.45 [0.32, 0.65], I2=0%). Effects on hospitalizations were inconsistent. Post hoc analyses suggested that NIV-related improvements in hypercapnia were associated with reduced hospital admissions across both populations. Little data were available comparing different types of NIV. CONCLUSION: The effectiveness of domiciliary NIV remains uncertain; however, some patients may benefit. Further research is required to identify these patients and to explore the relevance of improvements in hypercapnia in influencing clinical outcomes. Optimum time points for commencing domiciliary NIV and equipment settings need to be established. PMID- 27698561 TI - Influence of country-level differences on COPD prevalence. AB - PURPOSE: Studies suggest that COPD prevalence may vary between countries. We conducted an ecological study of data from COPD prevalence articles to assess the influence of differences in country-level risk factors on COPD prevalence. PATIENTS AND METHODS: Our study covered English language articles published during 2003-2014. Qualified articles used spirometry to assess COPD prevalence and used representative samples from national or subnational populations. Stepwise binomial regression was used to analyze associations between study- and country-level factors and COPD prevalence. RESULTS: Eighty articles provided 1,583 measures of COPD prevalence for subjects in different sex, age, and smoking categories for 112 districts in 41 countries. Adjusted prevalence rates for COPD were significantly lower for Australia/New Zealand and the Mediterranean and significantly higher for Latin America, compared to North America, Southeast Asia, and Northern Europe. Country-level socioeconomic development variables had an uneven and mixed association with COPD prevalence. High elevation above sea level was shown to be a protective factor for COPD. Study-level variables for the established risk factors of sex, age, and smoking explained 64% of variability in COPD prevalence. Country-level risk factors raised the explanatory power to 72%. Approximately 28% of worldwide variability in COPD prevalence remained unexplained. CONCLUSION: Our study suggests that COPD prevalence varies across world regions, even after adjustment for established risk factors. Major country level risk factors contributing to the worldwide epidemic of COPD remain to be investigated. PMID- 27698564 TI - Epilepsia partialis continua present with shoulder joint-trunk-hip joint rhythmic clonic seizure: a case report. AB - Epilepsia partialis continua (EPC) is a particular type of epilepsy which is distinguished from "common epilepsy" by its characteristic semiological features. However, unusual manifestations should be described in order to give awareness at clinical diagnosis. In this case report we describe a rare EPC case not previously reported, in which left shoulder joint-trunk-hip joint jerk was present for 1 week. Abnormal electroencephalogram and cerebrospinal fluid results supported a diagnosis of viral encephalitis. Antiepileptic treatment seemed effective. Our report emphasizes that a detailed functional anatomical analysis and synchronized electroencephalogram discharge should be done to avoid misdiagnosis in patients with synchronic shoulder-trunk-hip jerk symptoms. PMID- 27698562 TI - Multifunctional nanocomposite based on halloysite nanotubes for efficient luminescent bioimaging and magnetic resonance imaging. AB - A novel multifunctional halloysite nanotube (HNT)-based Fe3O4@HNT polyethyleneimine-Tip-Eu(dibenzoylmethane)3 nanocomposite (Fe-HNT-Eu NC) with both photoluminescent and magnetic properties was fabricated by a simple one-step hydrothermal process combined with the coupling grafting method, which exhibited high suspension stability and excellent photophysical behavior. The as-prepared multifunctional Fe-HNT-Eu NC was characterized using various techniques. The results of cell viability assay, cell morphological observation, and in vivo toxicity assay indicated that the NC exhibited excellent biocompatibility over the studied concentration range, suggesting that the obtained Fe-HNT-Eu NC was a suitable material for bioimaging and biological applications in human hepatic adenocarcinoma cells. Furthermore, the biocompatible Fe-HNT-Eu NC displayed superparamagnetic behavior with high saturation magnetization and also functioned as a magnetic resonance imaging (MRI) contrast agent in vitro and in vivo. The results of the MRI tests indicated that the Fe-HNT-Eu NC can significantly decrease the T2 signal intensity values of the normal liver tissue and thus make the boundary between the normal liver and transplanted cancer more distinct, thus effectively improving the diagnosis effect of cancers. PMID- 27698565 TI - Economic evaluation of eribulin as second-line treatment for metastatic breast cancer in South Korea. AB - BACKGROUND: Metastatic breast cancer (MBC) is associated with poor prognosis, particularly for those patients with human epidermal growth factor receptor (HER2)-negative tumor. Similar to the rest of the world, treatment options are limited in South Korea following first-line chemotherapy with anthracyclines and/or taxanes. This study examined the cost-effectiveness and cost-utility of eribulin in South Korean patients with HER2-negative MBC who have progressed after usage of at least one chemotherapeutic regimen for advanced disease (second line therapy). METHODS: A partition survival model was developed from the perspective of the South Korean health care system. The economic impact of introducing eribulin as second-line therapy for HER2-negative MBC was compared to that of capecitabine and vinorelbine. The analysis estimated incremental cost per life-year (LY), that is, cost-effectiveness, and cost per quality-adjusted life year (QALY), that is, cost-utility, of eribulin for management of HER2-negative MBC in South Korea. The model accounted for overall survival, progression-free survival, drug costs, grade 3/4 adverse events, and health care utilization. Deterministic and probabilistic sensitivity analyses were performed to identify uncertainty in the results of the economic evaluation. RESULTS: Second-line eribulin was associated with greater benefits in terms of LY and QALY, compared to capecitabine and vinorelbine. The incremental cost-effectiveness ratio was ?10.5M (approximately USD 9,200) per LY, and the incremental cost-utility ratio was ?17M (approximately USD 14,800) per QALY in the basecase analysis. The incremental cost-utility ratio ranged from ?12M (USD 10,461) to ?27M (USD 23,538) per QALY in the deterministic sensitivity analysis. In the probabilistic sensitivity analysis, >99% of the simulations were below ?50M (USD 42,300), and the lower and upper 95% confidence intervals were ?3M (USD 2,600) and ?24M (USD 20,900) per QALY, respectively. CONCLUSION: There currently exist a limited number of treatment choices for women with HER2-negative MBC. Eribulin is a cost effective option for second-line therapy in South Korea and should be added to the current indications for reimbursement. PMID- 27698563 TI - Functionalized immunostimulating complexes with protein A via lipid vinyl sulfones to deliver cancer drugs to trastuzumab-resistant HER2-overexpressing breast cancer cells. AB - BACKGROUND: Around 20%-30% of breast cancers overexpress the proto-oncogene human epidermal growth receptor 2 (HER2), and they are characterized by being very invasive. Therefore, many current studies are focused on testing new therapies against tumors that overexpress this receptor. In particular, there exists major interest in new strategies to fight breast cancer resistant to trastuzumab (Tmab), a humanized antibody that binds specifically to HER2 interfering with its mitogenic signaling. Our team has previously developed immunostimulating complexes (ISCOMs) as nanocapsules functionalized with lipid vinyl sulfones, which can incorporate protein A and bind to G immunoglobulins that makes them very flexible nanocarriers. METHODS AND RESULTS: The aim of this in vitro study was to synthesize and evaluate a drug delivery system based on protein A functionalized ISCOMs to target HER2-overexpressing cells. We describe the preparation of ISCOMs, the loading with the drugs doxorubicin and paclitaxel, the binding of ISCOMs to alkyl vinyl sulfone-protein A, the coupling of Tmab, and the evaluation in both HER2-overexpressing breast cancer cells (HCC1954) and non overexpressing cells (MCF-7) by flow cytometry and fluorescence microscopy. Results show that the uptake is dependent on the level of overexpression of HER2, and the analysis of the cell viability reveals that targeted drugs are selective toward HCC1954, whereas MCF-7 cells remain unaffected. CONCLUSION: Protein A functionalized ISCOMs are versatile carriers that can be coupled to antibodies that act as targeting agents to deliver drugs. When coupling to Tmab and loading with paclitaxel or doxorubicin, they become efficient vehicles for the selective delivery of the drug to Tmab-resistant HER2-overexpressing breast cancer cells. These nanoparticles may pave the way for the development of novel therapies for poor prognosis resistant patients. PMID- 27698566 TI - Calciphylaxis in peritoneal dialysis patients: a single center cohort study. AB - BACKGROUND: Calciphylaxis is a rare but devastating condition in end-stage renal disease (ESRD) patients. Most research in the field of calciphylaxis is focused on hemodialysis (HD) patients; however, data on calciphylaxis incidence, risk factors, and mortality in peritoneal dialysis (PD) patients are limited. METHODS: In this cohort study, we examined data from adult patients who initiated PD for ESRD management at our institute's PD unit from January 2001 to December 2015. Associations with the development of calciphylaxis were examined for clinical, laboratory, and medication exposures. Incidence of calciphylaxis and mortality in PD patients who developed calciphylaxis were analyzed. Treatments administered to treat calciphylaxis in PD patients were summarized. RESULTS: In this cohort of 63 patients, 7 patients developed calciphylaxis (incidence rate: 9.0 per 1,000 patient-years). Median age of PD patients who developed calciphylaxis was 50 years, 57% were white, 71% females, and 71% were previously on HD. Female sex, obesity, HD as a prior dialysis modality, recurrent hypotension, elevated time averaged serum phosphorous levels, reduced time-averaged serum albumin levels, and warfarin therapy were associated with increased calciphylaxis risk in univariate logistic regression analyses. Intravenous sodium thiosulfate was administered in 57% of PD patients who developed calciphylaxis. One-year mortality in PD patients who developed calciphylaxis was 71% despite multimodal treatment including sodium thiosulfate, hyperbaric oxygen, cinacalcet, and wound debridement. CONCLUSION: Calciphylaxis is a rare but frequently fatal condition in PD patients. Our study provides critical early insights into calciphylaxis incidence, risk factors, and prognosis in PD patients. Sample size and characteristics of patients included in our study limit generalizability to overall PD population and warrant examination in larger independent studies. PMID- 27698568 TI - Atypical scleromyxedema presenting with cutaneous and cardiovascular manifestations. AB - Scleromyxedema is part of a group of cutaneous mucinoses, characterized by a generalized papular eruption, dermal mucin deposition, and an increase in dermal collagen. This condition can be localized as discrete papular lichen myxedematous skin or as a systemic condition usually associated with paraproteinaemia. To date, there is no unifying treatment and is limited by rarity, small number of case reports, and the lack of randomized controlled trials. We describe the case of a 56-year-old gentleman with features of scleromyxedema who had cutaneous and cardiac involvement, and significant mediastinal lymphadenopathy without monoclonal gammopathy. PMID- 27698567 TI - Managing hyperthyroidism in pregnancy: current perspectives. AB - Hyperthyroidism in women who are of childbearing age is predominantly of autoimmune origin and caused by Graves' disease. The physiological changes in the maternal immune system during a pregnancy may influence the development of this and other autoimmune diseases. Furthermore, pregnancy-associated physiological changes influence the synthesis and metabolism of thyroid hormones and challenge the interpretation of thyroid function tests in pregnancy. Thyroid hormones are crucial regulators of early development and play an important role in the maintenance of a normal pregnancy and in the development of the fetus, particularly the fetal brain. Untreated or inadequately treated hyperthyroidism is associated with pregnancy complications and may even program the fetus to long term development of disease. Thus, hyperthyroidism in pregnant women should be carefully managed and controlled, and proper management involves different medical specialties. The treatment of choice in pregnancy is antithyroid drugs (ATDs). These drugs are effective in the control of maternal hyperthyroidism, but they all cross the placenta, and so need careful management and control during the second half of pregnancy considering the risk of fetal hyper- or hypothyroidism. An important aspect in the early pregnancy is that the predominant side effect to the use of ATDs in weeks 6-10 of pregnancy is birth defects that may develop after exposure to available types of ATDs and may be severe. This review focuses on four current perspectives in the management of overt hyperthyroidism in pregnancy, including the etiology and incidence of the disease, how the diagnosis is made, the consequences of untreated or inadequately treated disease, and finally how to treat overt hyperthyroidism in pregnancy. PMID- 27698569 TI - Robotic magnetic navigation for ablation of human arrhythmias. AB - Radiofrequency treatment represents the first choice of treatment for arrhythmias, in particular complex arrhythmias and especially atrial fibrillation, due to the greater benefit/risk ratio compared to antiarrhythmic drugs. However, complex arrhythmias such as atrial fibrillation require long procedures with additional risks such as X-ray exposure or serious complications such as tamponade. Given this context, the treatment of arrhythmias using robotic magnetic navigation entails a technique well suited to complex arrhythmias on account of its efficacy, reliability, significant reduction in X-ray exposure for both patient and operator, as well as a very low risk of perforation. As ongoing developments will likely improve results and procedure times, this technology will become one of the most modern technologies for treating arrhythmias. Based on the literature, this review summarizes the advantages and limitations of robotic magnetic navigation for ablation of human arrhythmias.

Complete descriptions, photographic illustrations, ecological information and preliminary IUCN conservation status are provided. For both species a data deficient (DD) status is proposed. These new species underline once again that the Monts de Cristal National Park is yet incompletely known botanically. PMID- 27698571 TI - Seed micromorphology of Orchis Tourn. ex L. (Orchidaceae) and allied genera growing in Edirne province, Turkey. AB - In this study, the seed micromorphologies of eight taxa of Anacamptis, Neotinea and Orchis growing around Edirne province (Turkey) were investigated using light microscopy and scanning electron microscopy (SEM). Slides prepared with glycerin jelly were used for measurements under the light microscope and fine details of seed testae characteristics were observed with SEM. Seeds of the investigated orchid taxa are fusiform shaped and of different shades of brown. Their lengths and widths are different among the taxa and range between 0.263-0.640 mm and 0.118-0.208 mm, respectively. Testa surfaces of Orchis mascula subsp. mascula, Orchis purpurea subsp. purpurea and Orchis simia subsp. simia, are smooth while those of Anacamptis coriophora, Anacamptis laxiflora subsp. laxiflora, Anacamptis morio subsp. morio, Anacamptis papilionacea and Neotinea tridentata subsp. tridentata are reticulate. An identification key based on seed morphologies and sizes is suggested for the first time, including testae structures of orchids growing in Edirne province. The overall results of the study showed that morphological structures of orchid's seeds could be used as diagnostic characters in identification. PMID- 27698572 TI - GuiaTreeKey, a multi-access electronic key to identify tree genera in French Guiana. AB - The tropical rainforest of Amazonia is one of the most species-rich ecosystems on earth, with an estimated 16000 tree species. Due to this high diversity, botanical identification of trees in the Amazon is difficult, even to genus, often requiring the assistance of parataxonomists or taxonomic specialists. Advances in informatics tools offer a promising opportunity to develop user friendly electronic keys to improve Amazonian tree identification. Here, we introduce an original multi-access electronic key for the identification of 389 tree genera occurring in French Guiana terra-firme forests, based on a set of 79 morphological characters related to vegetative, floral and fruit characters. Its purpose is to help Amazonian tree identification and to support the dissemination of botanical knowledge to non-specialists, including forest workers, students and researchers from other scientific disciplines. The electronic key is accessible with the free access software Xper2, and the database is publicly available on figshare: https://figshare.com/s/75d890b7d707e0ffc9bf (doi: 10.6084/m9.figshare.2682550).

AB - Long-term ecological studies are critical for providing key insights in ecology, environmental change, natural resource management and biodiversity conservation. However, island fire ecology is poorly understood. No previous studies are available that analyze vegetative changes in burned and unburned dry forest remnants on Wa'ahila Ridge, Hawai'i. This study investigates vegetation succession from 2008 to 2015, following a fire in 2007 which caused significant differences in species richness, plant density, and the frequency of woody, herb, grass, and lichens between burned and unburned sites. These findings infer that introduced plants have better competitive ability to occupy open canopy lands than native plants after fire. This study also illustrates the essential management need to prevent alien plant invasion, and to restore the native vegetation in lowland areas of the Hawaiian Islands by removing invasive species out-planting native plants after fire. PMID- 27698576 TI - Taxonomic implications from morphological and anatomical studies in the section Stenodiptera from the genus Grammosciadium (Apiaceae). AB - Grammosciadium pterocarpum subsp. bilgilii and Grammosciadium pterocarpum subsp. sivasicum from Turkey are herein described as two new subspecies, and the species Grammosciadium schischkinii is synonymied under Grammosciadium pterocarpum subsp. pterocarpum. Quantitative variation of morphological and anatomical characters have been analysed to provide discriminative characters between the taxa of section Stenodiptera and to provide a key to the species. The taxonomic status of the taxa has been discussed in light of these morphological and fruit anatomical data using multivariate statistics such as MANOVA and Principal Component Analysis. The results are also used to present a critical discussion of characters used to distinguish and determine different taxa within Grammosciadium. MANOVA showed that ten characters, except stylopodium and style length, differed significantly among the taxa, and the results were confirmed by Tukey tests and PCA analysis (except the character of fruit number). However, only ranges of the characters of sepal length, fruit length, fruit width, fruit width/wing width ratio, and width of fruit wing are not overlapped. Qualitative characters of petiolate stipular segments of lower leaves and presence of funicular oil ducts in transvers section of mericarps were found as diagnostic characters.

The eventual construction of several dams on the rivers Baker and Pascua required prospection of all groups of organisms including bryophytes, work that was facilitated by the recent construction of vehicular roads that now offer easy access to previously almost unaccessible locations. The results of intense bryophyte collecting during the austral summer of 2007 are here presented. A total of 260 moss taxa are reported for the province, corresponding to 256 species and four infraspecific taxa, of which 211 are new records for the province, 54 are new for Aisen Region, and two are new records for continental Chile (Pohlia longicollis (Hedw.) Lindb. and Rigodium toxarion var. robustum (Broth.) Zomlefer). Twelve species extend their known distribution ranges to the north, whereas 49 extend them to the south.

PMID- 27698579 TI - Anatomical and morphological spine variation in Gymnocalycium kieslingii subsp. castaneum (Cactaceae). AB - Although spine variation within cacti species or populations is assumed to be large, the minimum sample size of different spine anatomical and morphological traits required for species description is less studied. There are studies where only 2 spines were used for taxonomical comparison amnog species. Therefore, the spine structure variation within areoles and individuals of one population of Gymnocalycium kieslingii subsp. castaneum (Ferrari) Slaba was analyzed. Fifteen plants were selected and from each plant one areole from the basal, middle and upper part of the plant body was sampled. A scanning electron microscopy was used for spine surface description and a light microscopy for measurements of spine width, thickness, cross-section area, fiber diameter and fiber cell wall thickness. The spine surface was more visible and damaged less in the upper part of the plant body than in the basal part. Large spine and fiber differences were found between upper and lower parts of the plant body, but also within single areoles. In general, the examined traits in the upper part had by 8-17% higher values than in the lower parts. The variation of spine and fiber traits within areoles was lower than the differences between individuals. The minimum sample size was largely influenced by the studied spine and fiber traits, ranging from 1 to 70 spines. The results provide pioneer information useful in spine sample collection in the field for taxonomical, biomechanical and structural studies. Nevertheless, similar studies should be carried out for other cacti species to make generalizations. The large spine and fiber variation within areoles observed in our study indicates a very complex spine morphogenesis.

PMID- 27698587 TI - Flora-On: Occurrence data of the vascular flora of mainland Portugal. AB - The Flora-On dataset currently includes 253,310 occurrence records for the class Embryopsidae (vascular plants), comprising data collated via the platform http://flora-on.pt/ relating to observation records of vascular plants across mainland Portugal. Observations are uploaded directly to the database primarily by experienced botanists and naturalists, typically on a weekly basis, and consist of geo-referenced data points for species (or infraspecific taxa) along with their date of observation and phenological state. The Flora-On project aims to compile and make publicly accessible chorological, ecological, morphological and photographic information for the entire vascular flora of Portugal. The project's website offers powerful query and visualization capabilities, of which we highlight the probabilistic bioclimatic and phenological queries which operate based on the empirical density distributions of species in those variables. Flora On was created and continues to be maintained by volunteers who are Associate members of Sociedade Portuguesa de Botanica (Botanical Society of Portugal). Given its focus on research-grade and current data, the Flora-On project represents a significant contribution to the knowledge of the present distribution and status of the Portuguese flora.

PMID- 27698590 TI - Dosimetric feasibility of an "off-breast isocenter" technique for whole-breast cancer radiotherapy. AB - AIM: To investigate the viability of placing the treatment isocenter at the patient midline for breast cancer radiotherapy in order to avoid the risk of collisions during image-guided setup and treatment delivery. BACKGROUND: The use of kilovoltage orthogonal setup images has spread in last years in breast radiotherapy. There is a potential risk of an imaging system-patient collision when the isocenter is laterally placed. MATERIALS AND METHODS: Twenty IMRT plans designed by placing the isocenter within the breast volume ("plan_ref"), were retrospectively replanned by shifting the isocenter at the patient's midline ("plan_off-breast"). An integrated simultaneous boost (SIB) technique was used. Multiple metrics for the planning target volumes (PTVs) and organs at risk (OARs) were compared for both approaches using a paired t test. RESULTS: Comparing plan_ref vs. plan_off-breast, no significant differences in PTV coverage (V95%) were found (96.5% vs. 96.2%; p = 0.361 to PTVbreast; 97.0% vs. 97.0%; p = 0.977 to PTVtumor_bed). With regard to OARs, no substantial differences were observed in any analyzed metric: V5Gy (30.3% vs. 31.4%; p = 0.486), V20Gy (10.3% vs. 10.3%; p = 0.903) and mean dose (7.1 Gy vs. 7.1 Gy; p = 0.924) to the ipsilateral lung; V5Gy (11.2% vs. 10.0%; p = 0.459), V30Gy (0.7% vs. 0.6%; p = 0.251) and mean dose (2.3 Gy vs. 2.2 Gy; p = 0.400) to the heart; and average dose to the contralateral breast (0.4 Gy vs. 0.5 Gy; p = 0.107). CONCLUSIONS: The off-breast isocenter solution resulted in dosimetrically comparable plans as the reference technique, avoiding the collision risk during the treatment session. PMID- 27698591 TI - SPIDERplan: A tool to support decision-making in radiation therapy treatment plan assessment. AB - AIM: In this work, a graphical method for radiotherapy treatment plan assessment and comparison, named SPIDERplan, is proposed. It aims to support plan approval allowing independent and consistent comparisons of different treatment techniques, algorithms or treatment planning systems. BACKGROUND: Optimized plans from modern radiotherapy are not easy to evaluate and compare because of their inherent multicriterial nature. The clinical decision on the best treatment plan is mostly based on subjective options. MATERIALS AND METHODS: SPIDERplan combines a graphical analysis with a scoring index. Customized radar plots based on the categorization of structures into groups and on the determination of individual structures scores are generated. To each group and structure, an angular amplitude is assigned expressing the clinical importance defined by the radiation oncologist. Completing the graphical evaluation, a global plan score, based on the structures score and their clinical weights, is determined. After a necessary clinical validation of the group weights, SPIDERplan efficacy, to compare and rank different plans, was tested through a planning exercise where plans had been generated for a nasal cavity case using different treatment planning systems. RESULTS: SPIDERplan method was applied to the dose metrics achieved by the nasal cavity test plans. The generated diagrams and scores successfully ranked the plans according to the prescribed dose objectives and constraints and the radiation oncologist priorities, after a necessary clinical validation process. CONCLUSIONS: SPIDERplan enables a fast and consistent evaluation of plan quality considering all targets and organs at risk. PMID- 27698592 TI - Treatment planning study of Volumetric Modulated Arc Therapy and three dimensional field-in-field techniques for left chest-wall cancers with regional lymph nodes. AB - AIM: This study aims to investigate whether there are dosimetric advantages to using VMAT (Volumetric Modulated Arc Therapy) for left-sided chest-wall patients over the three-dimensional conformal field-in-field (FinF) technique. BACKGROUND: There is a lack of dosimetric studies dedicated for chest-wall patients. Potential dosimetric advantage could be obtained using VMAT due to complex geometry of PTVs (Planning Target Volumes) and OARs (Organs at Risk) in chest wall and lymph nodes. MATERIALS AND METHODS: VMAT and FinF plans were generated and evaluated based on DVHs (Dose Volume Histograms) for both PTVs and OARs for 22 left-sided chest-wall patients with involved regional nodes. PTV HIs (Homogeneity Indices) and CIs (Conformity Indices), and EUDs (Equivalent Uniform Doses) for PTVs and OARs were also evaluated for comparisons between VMAT and FinF. RESULTS: FinF planning met PTV criteria adequately in all cases except two. In these two cases, VMAT was able to meet PTV criteria adequately. VMAT demonstrated significant reduction in left lung V20 Gy in chest-wall patients compared to FinF plans. The volumes of the right lung and right breast receiving 5 Gy were much higher in VMAT than those in FinF for all patients. CONCLUSIONS: Compared to the FinF technique, there is a generally limited benefit using VMAT for left-sided chest-wall patients due to large low-dose-bath to OARs with insignificant improvement in PTV coverage. In case where FinF planning cannot meet dose constrains, VMAT provides a viable option. The use of VMAT planning over the FinF technique in chest-wall cancers should be carefully analyzed on an individual basis.

AB - AIM: The goal of this prospective study was to assess the effectiveness of a hypofractionated accelerated regime in treatment of the larynx cancer. BACKGROUND: Multiple radiotherapy delivery regimes are used for treatment of the larynx cancer. Hypofractionated regimes could provide similar results with reduced use of radiotherapy facilities. MATERIAL AND METHODS: 223 patients with squamous cell carcinoma of the upper or middle larynx have been treated with 63 Gy delivered in 28 fractions of 2.25 Gy during 38 days, 5 fractions per week. The study endpoints were overall survival, progression-free survival, early and late treatment toxicity. Standard and accelerated radiotherapy groups from the study published by Hliniak et al.20 served as controls. RESULTS: Five-year actuarial overall survival was 87.5% in the study group, 84.5% in the control group receiving accelerated radiotherapy (33 fractions of 2.0 Gy, 6 fractions per week) and 86.2% in the control group (33 fractions of 2.0 Gy, 5 fractions per week). Five-year progression-free survival was 73.6%, 77.2% and 66.2%, respectively. Overall, treatment toxicity and complication rates did not differ between the study group and the control groups. CONCLUSIONS: The hypofractionated accelerated radiotherapy protocol using 5 fractions per week reduced the use of radiotherapy facilities. There was no significant difference in overall survival and progression-free survival between the study and control groups treated with accelerated or standard radiotherapy. PMID- 27698594 TI - THE COMPARING OF ANTIMICROBIAL ACTIVITY OF CSN1S2 PROTEIN OF FRESH MILK AND YOGHURT GOAT BREED ETHAWAH INHIBITED THE PATHOGENIC BACTERIA. AB - BACKGROUND: Goat milk is reported to have antimicrobial activity of several pathogen bacteria that contained on food materials. The research related with antimicrobial activity of Alpha-S2 casein from goat milk is relatively less than other casein components. Herein, we reported the antimicrobial activity of caprine Alpha-S2 Casein (CSN1S2) protein from Ethawah breed goat milk and yoghurt in Gram positive (Listeria monocytogenes, Staphylococcus aureus and Bacillus cereus) and negative pathogen bacteria (Escherichia coli, Salmonella typhi and Shigella flexneri). Those bacteria were known as pathogens that caused gastrointestinal infection. METHODS: Serial dilution and agar diffusion analysis with three different concentrations of caprine CSN1S2, 1.25 mg/ml, 2.5 mg/ml, and 5 mg/ml were used to test the inhibition effect of protein on the viability of bacteria cells. The inhibitory activity of caprine CSN1S2 was based on dose dependent manner. Agar diffusion analysis was showed the larger diameter of clear zone at B. cereus and S. flexneri. RESULTS: The serial dilution analysis was shown the inhibition of almost in all groups of bacteria with concentration 5 mg/ml higher by CSN1S2 protein of goat fresh milk than yogurt. The inhibitory activity caprine CSN1S2 protein of fresh milk was shown a vary inhibition clear zone with optimal concentration 5 mg/ml, however CSN1S2 protein of goat yogurt intermediate effectively was only in gram negative bacteria. The weakness bacteria against inhibition activity caprine CSN1S2 protein was B. cereus (Gram positive) and S. flexneri (Gram negative). Meanwhile the strongest bacteria against inhibition activity caprine CSN1S2 protein was S. typhi (Gram negative), may cause in this bacteria has lipopolysaccharide prevent to interact with that protein as proper. CONCLUSION: This study result concluded that the caprine CSN1S2 protein has inhibition activity in opposition to pathogenic bacteria by optimal concentration 5 mg/ml in all bacteria and indicated caprine CSN1S2 protein as anti-microbial agent.

RESULTS: According to the results, in the 12th day of treatment, 96 patients exhibited moderate self esteem, 102 patients had internal locus of control, and the score of their overall quality of life was 40.43+/-12.71. Furthermore, Pearson's correlation coefficient indicated that a significant and positive relationship was observed between locus of control and quality of life during different treatment stages. CONCLUSION: It seems that quality of life improves during addiction treatment stages due to improvement of personality traits including locus of control and self-esteem. Therefore, consultation methods as a very crucial priority in addiction rehabilitation centers shall be taken into account by the health sector authorities and managers and can play an essential role in enhancing quality of life.

AB - INTRODUCTION: Adherence as a concept includes various types of health-related behavior. Better medical adherence leads to improved disease control and fewer diabetes-related complications. Quality of life and medication adherence are interrelated. Patients with diabetes who adhere to their treatment can experience an improvement in quality of life and vice versa. AIM: To assess treatment adherence in patients with type II diabetes, as well as the connection between adherence and quality of life. METHODOLOGY: A descriptive non-experimental study was conducted in a provincial hospital in Northern Greece. The sample examined was a convenience sample consisting of 108 patients with type II diabetes mellitus. They completed the "Diabetes Self-Care Activities Questionnaire" and SF 36 "Quality of Life Questionnaire". RESULTS: Participants demonstrated good adherence to diet and blood test / blood glucose test routines, but did not experience high levels of quality of life. The type of treatment affected the adherence to blood tests with a statistically significant difference (p=0,000). Also, marital status affected mental health with a statistically significant difference (p=0,032). The adherence sub scales are correlated with the all domains of quality of life. CONCLUSIONS: According to our findings, it is important to plan interventions to enhance adherence to other types of treatment and to help patients to further improve their quality of life.

AB - INTRODUCTION: One of the most common and potential life threatening complications of pregnancy is pregnancy induced hypertension. This cross-sectional study aimed to investigate the relationship between platelet count and pregnancy induced hypertension. MATERIAL AND METHODS: Twenty (20) patients (subjects) and twenty (20) healthy pregnant women (control) visiting the Obstetrics and Gynecology Hospital University of "Koco Gliozheni" Tirana Albania were registered in the study and followed during their pregnancy. Both, subjects and control participants were subject to platelet count manually performed using standard methods on. RESULTS: The mean platelet count of the control group (38448+/ 235500) was significantly higher than that of the subject group (217050+/ 50780.7) (p<0.03). In the first and second trimester was more prevalent low platelet counting with the mean platelet count (107 +/-57.3) and (101 +/-63.4), respectively. The mean age at marriage in subjects with PIH was found to be with low platelet count. Regular monitoring of platelet counts in women with Pregnancy Induced Hypertension must be subject of the management protocols.

AB - BACKGROUND: Each year, more than forty million abortions are occurred whole of the world. Misoprostol is a prostaglandin analogue with a strong uterotonic effect. The present study aimed to compare the efficacy of Misoprostol in first trimester abortion through two sublingual and vaginal routes of administration. METHODS: This randomized clinical trial was conducted on 52 consecutive women in first trimester candidate for pregnancy termination because of fetal IUFD or missed abortion in sonography reports. The patients were hospitalized and then randomly assigned to receive sublingual Misoprostol (400 ug, n 27) or vaginal Misoprostol (400 ug placed in posterior fornix, n = 25). FINDINGS: None of the pregnant in the sublingual group developed complete abortion at the end of follow up time, while 36% of women inducted with vaginal misoprostol experienced complete abortion indicating a intergroup significant difference (p = 0.001). Compared with vaginal group, those women in sublingual group experienced more complications including diarrhea (22.2% versus 20.0%), nausea and vomiting (22.2% versus 0.0%), and abdominal pain (3.7% versus 0.0%). CONCLUSION: The use of Misoprostol in vaginal route results in more abortion completeness as well as lower complication rate as compared to sublingual prescription of the drug. PMID- 27698602 TI - PARENTS' ATTITUDES ON THE INTRODUCTION OF HEALTH EDUCATION IN THE EDUCATION SYSTEM. AB - INTRODUCTION: We explored parents' views on the introduction of HE into the educational system, as well as differences in the degree of agreement, depending on the gender of the respondents, the school which the children attend and children's age. PATIENTS AND METHODS: Examinees in this study were parents (N = 531) of children attending primary and secondary schools in the area of Municipality Livno. The study was conducted by using cross-sectional study and a special questionnaire was created assessing attitudes on the introduction of HE in the education system which contains 26 items. RESULTS: Parents have positively disposed towards the introduction of HE in schools (M = 2.85) if it would be carried out according to previously anticipated and clearly defined literature (M = 3.89), which they should be pre-acquainted with (M = 3.78). They also consider that the lecturers should be exclusively health workers (M = 3.50) and certainly should cover the topics of the quality of human life (M = 4.07), the prevention of addiction (M = 4.03), prevention of bullying (M = 4.14) and the culture of social communication (M = 4.15). Surely the content of the lectures should be adapted to the age of the child and should be adjusted with the principles and values imposed by the religion (M = 3.61). Parents most varied in their views when it comes to the introduction of sex education in schools (M = 2.9, SD = 1.53), however, if the contents would correspond with the age of the child (M = 3.7). There are no gender differences on the issue of the introduction of HE in schools (t = 0.018, DF = 499, p> 0.05), as well as differences between the schools (F = 1.937, DF = 5,520, p> 0.05), nor between children of various age groups (F = 1.667, DF = 2,523, p> 0.05). PMID- 27698601 TI - THE MANAGEMENT OF TRANSFUSION SERVICES, ANALYSIS AND ASSESSMENT. AB - INTRODUCTION: The hospital blood bank (HBB) need to timely provide adequate amounts of blood and blood products for surgeries. For various surgical programs are performed assessments of the average number of blood doses needed for surgery. By using two types of requisitions BT/AB (blood type/antibody) and BT/AB/MT (blood type/antibody/match test) for pretransfusion immunohaematological testing in General Hospital "Prim. Dr. Abdulah Nakas" is achieved more rational consumption of blood and blood derivatives and financial savings through reduced number of matching tests (MT). GOAL: To determine the total amount of pre operative requisitions (BT/AB and BT/AB/MT) for blood and blood products at surgical departments of the General Hospital "Prim. Dr. Abdulah Nakas" in the period from June 1, 2014 - December 31, 2014 and analyze the consumption/return of blood in reserve in relation to the surgical disciplines, the total number of savings in MT. Conduct assessments MSBOS (Maximum Surgical Blood Ordering Schedule). RESULTS: The total amount of preoperative requisitions for blood and blood products in surgical wards was 927 requests from which 623 demands or 67.2% is tested by BT/MT, while 304 or 32.8% was tested by BT/AB/MT. Transfused in total was 617 units of blood and blood products, 275 units were not transfused. Probability of transfusions for surgery was 51.3, the highest in the case of surgical intensive care 70.4 and the lowest for the department of general surgery 37.2%. Assessment of indicators of efficient resource management indicates they are the best at the delivery ward 0.89, while a total for surgical wards is 0.69. In total for surgery on the average were required 2.1 units of blood. By using two types of requisitions for pretransfusion immunohaematological testing (BT/AB and CG/AB/MT) is achieved more rational use of MT. In 623 requests for BT/AB only 61 MT were performed. Average of blood units issued in accordance with these requirements is 0.08 and the savings in the number of MT amounts to 562. PMID- 27698603 TI - THE EFFECT OF EDUCATIONAL INTERVENTION ON KNOWLEDGE AND SELF-EFFICACY FOR PAIN CONTROL IN PATIENTS WITH MULTIPLE SCLEROSIS. AB - INTRODUCTION: Multiple Sclerosis (MS) is one of the most common autoimmune diseases affecting the central nervous system. The prevalence of it is increasing in our country too. The pain from disorders can affect quality of life. Several studies have pointed to the improvement of patients through educational intervention. This study attempted to evaluate the effectiveness of an educational intervention based on raising the awareness and self-efficacy for pain control among patients with multiple sclerosis during 2015 under the coverage of Isfahan MS Society (IMSS). MATERIALS AND METHODS: This was a quasi experimental study involving pre-test, post-test and randomized control group conducted on 100 patients with MS referred to the Isfahan MS Society (IMSS). The educational intervention group learned the pain management self-care lesson during 4 weekly sessions. The data were collected through a self-structured questionnaire with adequate validity and reliability, containing demographic data, awareness and self-efficacy of pain control. The data were assessed through descriptive and analytical tests assisted by SPSS 17. The significant level was considered as P<0.05. RESULTS: Concerning the questionnaire, 96% of the items were responded. Most participants were women. The frequency distribution of demographic variables was not significantly different between the two pre-test groups. After the intervention, the mean score of knowledge and efficacy among patients in the intervention group was significantly higher than the control group (P<0.001). CONCLUSIONS: Educational interventions can improve awareness and self-efficacy for pain control among patients with MS. Therefore, such interventions can be designed to reduce physical and psychological complications following multiple sclerosis.

AB - AIM: The goal of this study was to examine the general satisfaction of mothers of children with autism spectrum disorder (ASD) with treatment opportunities for their children in Bosnia and Herzegovina. An additional goal was to assess the level of mothers' satisfaction with their own involvement in the creation and implementation of Individual Education Plans. METHODS: The sample consisted of 98 mothers of children with ASD. Mothers answered to questions related to their perceived satisfaction with treatment options. RESULTS: The results of this study indicated that mothers are generally satisfied with educational opportunities for their children (61.2%). However, their satisfaction with involvement in the creation and implementation of Individual Education Programs was much lower (35.7%). Most comments of the mothers were that the treatment options should be more widely available and that the educational programs could be improved. CONCLUSIONS: Parents of children with ASD should have more information on the treatment options available for their children. More educational opportunities need to be offered to children with ASD in Bosnia and Herzegovina. PMID- 27698605 TI - THE QUANTITATIVE STUDY OF THE FACULTY MEMBERS PERFORMANCE IN DOCUMENTATION OF THE MEDICAL RECORDS IN TEACHING HOSPITALS OF MAZANDARAN UNIVERSITY OF MEDICAL SCIENCES. AB - INTRODUCTION: Documentation of patients' medical records has been always emphasized because medical records are as a means to be applied by patients, all medical staff, quality evaluations of health care, lawsuits, medical education and, etc. Regarding to this, each of the data elements available in the sheets of medical records has their own values. The rate of completion indicates the importance of the medical recorders for faculty member. So in this article the researcher evaluates the completion of medical records in the teaching hospitals of Mazandaran University of Medical Sciences. METHODS AND MATERIALS: This cross- sectional study has been conducted to review the patients' medical cases in five teaching university hospitals. To collect data, a check list was mode based on data element arrangement in four main sheets of admission and discharge, summery, patients' history and clinical examination and progress note sheets. Recorded data were defined as "Yes" with the value 1, not recorded data were defined as "No" with the value 2, and not used data were defined for cases in which the mentioned variable had no use with the value Zero. The overall evaluation of the rate of documentation was considered as %95 -100 equal to "good", 75-94% equal to average and under 75% was considered as "poor". Using the sample volume formula, 281 cases were randomly stratified reviewed. The data were analyzed by the software SPSS version 19 and descriptive statistical scales. RESULTS: The results have shown that the overall documentation rate in all the four sheets was 62% and in a poor level. There was no big difference in the average documentation among the hospital. Among the educational group, the gynecology and infection groups are equal to each other and had the highest record average (68%). Within the all groups, the highest rate has belonged to the documentation of signatures (91%). CONCLUSION: Regarding to the overall assessment that documentation rate was in a poor level, more attempt should be made to achieve a better condition. Even if a data element of the sheets seems meaningless, unnecessary and duplicated, it should not be ignored and skipped. In order to solve such problems, it is suggested that medical records sheets and the elements that seem unnecessary, should be reviewed in relevant committees. PMID- 27698606 TI - BELIEFS ABOUT MEDICINES IN PATIENTS WITH HYPERTENSION: THE INSTRUMENT VALIDITY AND RELIABILITY IN IRAN. AB - PURPOSE: Despite the importance of patients believes as one of the most important predictors of treatment adherence behavior, it is rarely considered in numerous studies. Then the current survey was aimed to develop and study the beliefs about medicines questionnaire (BMQ) in patients with hypertension. MATERIALS AND METHODS: The BMQ developed by Horn and et al. was used in the current study. This questionnaire included 18 questions in both public and private beliefs regarding drug. Face and content validity of the tool was investigated using expert's panel. In final, aforementioned tool was tested in 612 participants. To explore structure validity and internal consistency, exploratory and confirmatory factor analysis and alpha coefficient was conducted. To evaluate the final validity of instrument, the mean score of the beliefs about medicines of patients with appropriate medication adherence were compared to patients without medication adherence. RESULTS: The mean age of patients was 44.08 +/- 10.38 years. Women were 314 of participants. Calculated face validity by the impact score for each item indicated that all the items of the questionnaire had the impact score of more than 1.5. In total, all items had scored higher than 0.79 by considering 18 items for content validity. The average of content validity index for the questionnaire was 0.93. Load of factors were in the range of 0.51 to 0.79. Four items explained % 57 of the total variance. Comparison of all instrument items in the two groups showed that patients with good adherence had higher score in 15 items (% 83 of all items). CONCLUSION: The findings suggested that the BMQ in patients with hypertension as a valid and reliable instrument can be used to evaluate the patients' medication adherence.

Using this analysis, managers can plan for such events and develop scenarios for them to have better performance for the future events. PMID- 27698607 TI - HYPERHOMOCYSTEINEMIA AND ITS TREATMENT IN PATIENTS WITH PARKINSON'S DISEASE. AB - INTRODUCTION: Homocysteine is process-product of methionine demethylation. It has proatherogenic, prothrombotic, prooxidative, proapoptotic, osteoporotic, neurotoxic, neuroinflamatory, and neurodegenerative effects. Hyperhomocysteinemia correlates with C667T MTHFR mutation, decrease of folic acid and vitamin B, as well as prolonged use of certain medications. MATERIALS AND METHODS: We measured levels of homocysteine in thirty patients (15::15) with "de novo" Parkinson's disease, with average age 64.17 +/- 13.19 (28-82) years (Department of Neurology, University Clinical Center Tuzla). Normal level of homocysteine for women was 3.36-20.44 micromole/l and 5.9-16 micromole/l for men. We followed the effects of medicament approach (folic acid) every six months for next five years. RESULTS: 20% of patients with "de novo" Parkinson's disease exhibited hyperhomocysteinemia. An average level of homocysteine was 13.85 +/- 5.82 micromole/l. Differences due to age and homocysteine levels, regardless of sex, were not concluded. For the next five years intake of folic acid (periodically, 1 2 months, 5 mg per day, orally) was effective to normalized levels of homocysteine in all. CONCLUSION: Hyperhomocysteinemia is present in every fifth patient with "de novo" Parkinson's disease. Folic acid is medication of choice in treatment of hyperhomocysteinemia coexisting with Parkinson's disease. PMID- 27698609 TI - EPIDEMIOLOGICAL ANALYSIS OF OCULAR MELANOMA IN UNIVERSITY CLINIC CENTER IN TUZLA, BOSNIA AND HERZEGOVINA. AB - AIM: Melanoma represents a malignant tumour arising from melanocytes. Uveal melanoma is the most common primary ocular malignancy among the adult population. The aim of the study was to examine epidemiological characteristics of ocular melanoma in University Clinic Centre in Tuzla, Bosnia and Herzegovina from January 2001 till November 2015. METHODS AND MATERIALS: In this retrospective study we used all available medical documentation to investigate the clinical findings which included age, gender, tumour size, histopathological features and the precise anatomic origin of the ocular melanoma. RESULTS: Over the 14 year period of this study, there were 32 patients with microscopically confirmed ocular melanoma at the Department of Pathology. All malignant melanoma were uveal origin. DISCUSSION AND CONCLUSION: For early detection of the disease, regular checkups are necessary, especially in older population. As there is a limited number of reports on the epidemiology of malignant tumors of eye and ocular adnex in our region, this is very important study. We conclude that this is a first study in Bosnia and Herzegovina that document the number of uveal melanomas. PMID- 27698610 TI - BOLOGNA MODEL OF MEDICAL EDUCATION-UTOPIA OR REALITY. AB - Higher education in Europe and in the Balkan's countries is undergoing major reforms. The Bologna Process was a major reform created with the claimed goal of providing responses to issues such as the public responsibility for higher education and research, higher education governance, the social dimension of higher education and research, and the values and roles of higher education and research in modern, globalized, and increasingly complex societies with the most demanding qualification needs. Changes in the curricula, modernization of facilities and their alignment with the programs of other European universities, employment of a larger number of assistants, especially in the clinical courses at our universities are necessary. Also, it is necessary to continue to conduct further detailed analysis and evaluation of teaching content and outcomes in the future. In this review authors expressed their views and experience of using Bologna model of education in the Balkan's countries with emphasis on Bosnia and Herzegovina and the Republic of Macedonia. PMID- 27698611 TI - Moving Beyond Readability Metrics for Health-Related Text Simplification. AB - Limited health literacy is a barrier to understanding health information. Simplifying text can reduce this barrier and possibly other known disparities in health. Unfortunately, few tools exist to simplify text with demonstrated impact on comprehension. By leveraging modern data sources integrated with natural language processing algorithms, we are developing the first semi-automated text simplification tool. We present two main contributions. First, we introduce our evidence-based development strategy for designing effective text simplification software and summarize initial, promising results. Second, we present a new study examining existing readability formulas, which are the most commonly used tools for text simplification in healthcare. We compare syllable count, the proxy for word difficulty used by most readability formulas, with our new metric 'term familiarity' and find that syllable count measures how difficult words 'appear' to be, but not their actual difficulty. In contrast, term familiarity can be used to measure actual difficulty. PMID- 27698612 TI - Distinct Ecological Niche of Anal, Oral, and Cervical Mucosal Microbiomes in Adolescent Women. AB - Human body sites represent ecological niches for microorganisms, each providing variations in microbial exposure, nutrient availability, microbial competition, and host immunological responses. In this study, we investigated the oral, anal, and cervical microbiomes from the same 20 sexually active adolescent females, using culture-independent, next-generation sequencing. DNA from each sample was amplified for the bacterial 16S rRNA gene and sequenced on an Illumina platform using paired-end reads. Across the three anatomical niches, we found significant differences in bacterial community composition and diversity. Overall anal samples were dominated with Prevotella and Bacteriodes, oral samples with Streptococcus and Prevotella, and cervical samples with Lactobacillus. The microbiomes of a few cervical samples clustered with anal samples in weighted principal coordinate analyses, due in part to a higher proportion of Prevotella in those samples. Additionally, cervical samples had the lowest alpha diversity. Our results demonstrate the occurrence of distinct microbial communities across body sites within the same individual. PMID- 27698614 TI - Gut Microbiome and Infant Health: Brain-Gut-Microbiota Axis and Host Genetic Factors. AB - The development of the neonatal gut microbiome is influenced by multiple factors, such as delivery mode, feeding, medication use, hospital environment, early life stress, and genetics. The dysbiosis of gut microbiota persists during infancy, especially in high-risk preterm infants who experience lengthy stays in the Neonatal intensive care unit (NICU). Infant microbiome evolutionary trajectory is essentially parallel with the host (infant) neurodevelopmental process and growth. The role of the gut microbiome, the brain-gut signaling system, and its interaction with the host genetics have been shown to be related to both short and long term infant health and bio-behavioral development. The investigation of potential dysbiosis patterns in early childhood is still lacking and few studies have addressed this host-microbiome co-developmental process. Further research spanning a variety of fields of study is needed to focus on the mechanisms of brain-gut-microbiota signaling system and the dynamic host-microbial interaction in the regulation of health, stress and development in human newborns. PMID- 27698616 TI - Human Microbiota and Ophthalmic Disease. AB - The human ocular surface, consisting of the cornea and conjunctiva, is colonized by an expansive, diverse microbial community. Molecular-based methods, such as 16S rRNA sequencing, has allowed for more comprehensive and precise identification of the species composition of the ocular surface microbiota compared to traditional culture-based methods. Evidence suggests that the normal microbiota plays a protective immunological role in preventing the proliferation of pathogenic species and thus, alterations in the homeostatic microbiome may be linked to ophthalmic pathologies. Further investigation of the ocular surface microbiome, as well as the microbiome of other areas of the body such as the oral mucosa and gut, and their role in the pathophysiology of diseases is a significant, emerging field of research, and may someday enable the development of novel probiotic approaches for the treatment and prevention of ophthalmic diseases. PMID- 27698613 TI - The Influence of the Gut Microbiota on Host Physiology: In Pursuit of Mechanisms. AB - The results generated from the NIH funded Human Microbiome Project (HMP) are necessarily tied to the overall mission of the agency, which is to foster scientific discoveries as a basis for protecting and improving health. The investment in the HMP phase 1 accomplished many of its goals including the preliminary characterization of the human microbiome and the identification of links between microbiome diversity and disease states. Going forward, the next step in these studies must involve the identification of the functional molecular elements that mediate the positive influence of a eubiotic microbiome on health and disease. This review will focus on recent advances describing mechanistic events in the intestine elicited by the microbiome. These include symbiotic bacteria-induced activation of redox-dependent cell signaling, the bacterial production of short chain fatty acids and ensuing cellular responses, and the secretion of bacteriocins by bacteria that have anti-microbial activities against potential pathogens. PMID- 27698617 TI - Unraveling the Dynamics of the Human Vaginal Microbiome. AB - Four Lactobacillus species, namely L. crispatus , L. iners, L. gasseri, and L. jensenii, commonly dominate the vaginal communities of most reproductive-age women. It is unclear why these particular species, and not others, are so prevalent. Historically, estrogen-induced glycogen production by the vaginal epithelium has been proffered as being key to supporting the proliferation of vaginal lactobacilli. However, the 'fly in the ointment' (that has been largely ignored) is that the species of Lactobacillus commonly found in the human vagina cannot directly metabolize glycogen. It would appear that this riddle has been solved as studies have demonstrated that vaginal lactobacilli can metabolize the products of glycogen depolymerization by alpha-amylase, and fortunately, amylase activity is found in vaginal secretions. These amylases are presumed to be host derived, but we suggest that other bacterial populations in vaginal communities could also be sources of amylase in addition to (or instead of) the host. Here we briefly review what is known about human vaginal bacterial communities and discuss how glycogen-derived resources and resource competition might shape the composition and structure of these communities. PMID- 27698615 TI - Breathing Better Through Bugs: Asthma and the Microbiome. AB - Asthma is a highly heterogeneous disease characterized by inflammation of the airways, which invokes symptoms such as wheeze, dyspnea, and chest tightness. Asthma is the product of multiple interconnected immunological processes and represents a constellation of related, but distinct, disease phenotypes. The prevalence of asthma has more than doubled since the 1980s, and efforts to understand this increase have inspired consideration of the microbiome as a key player in the pathophysiology and regulation of this disease. While recent years have seen an explosion of new research in this area, researchers are only beginning to untangle to mechanisms by which the microbiome may influence asthma. This review will focus on the relationship between the microbiome and the immune system and how this influences development of asthma. This review will also highlight evidence that may point the way toward new therapies and potential cures for this ancient respiratory foe. PMID- 27698618 TI - An Ecological Framework of the Human Virome Provides Classification of Current Knowledge and Identifies Areas of Forthcoming Discovery. AB - Recent advances in sequencing technologies have opened the door for the classification of the human virome. While taxonomic classification can be applied to the viruses identified in such studies, this gives no information as to the type of interaction the virus has with the host. As follow-up studies are performed to address these questions, the description of these virus-host interactions would be greatly enriched by applying a standard set of definitions that typify them. This paper describes a framework with which all members of the human virome can be classified based on principles of ecology. The scaffold not only enables categorization of the human virome, but can also inform research aimed at identifying novel virus-host interactions. PMID- 27698619 TI - Metagenomic Assembly: Overview, Challenges and Applications. AB - Advances in sequencing technologies have led to the increased use of high throughput sequencing in characterizing the microbial communities associated with our bodies and our environment. Critical to the analysis of the resulting data are sequence assembly algorithms able to reconstruct genes and organisms from complex mixtures. Metagenomic assembly involves new computational challenges due to the specific characteristics of the metagenomic data. In this survey, we focus on major algorithmic approaches for genome and metagenome assembly, and discuss the new challenges and opportunities afforded by this new field. We also review several applications of metagenome assembly in addressing interesting biological problems. PMID- 27698621 TI - The Impact of the Gut Microbiota on Drug Metabolism and Clinical Outcome. AB - The significance of the gut microbiota as a determinant of drug pharmacokinetics and accordingly therapeutic response is of increasing importance with the advent of modern medicines characterised by low solubility and/or permeability, or modified-release. These physicochemical properties and release kinetics prolong drug residence times within the gastrointestinal tract, wherein biotransformation by commensal microbes can occur. As the evidence base in support of this supplementary metabolic "organ" expands, novel opportunities to engineer the microbiota for clinical benefit have emerged. This review provides an overview of microbe-mediated alteration of drug pharmacokinetics, with particular emphasis on studies demonstrating proof of concept in vivo. Additionally, recent advances in modulating the microbiota to improve clinical response to therapeutics are explored. PMID- 27698622 TI - Treating Obesity and Metabolic Syndrome with Fecal Microbiota Transplantation. AB - The worldwide prevalence of metabolic syndrome, which includes obesity and its associated diseases, is rising rapidly. The human gut microbiome is recognized as an independent environmental modulator of host metabolic health and disease. Research in animal models has demonstrated that the gut microbiome has the functional capacity to induce or relieve metabolic syndrome. One way to modify the human gut microbiome is by transplanting fecal matter, which contains an abundance of live microorganisms, from a healthy individual to a diseased one in the hopes of alleviating illness. Here we review recent evidence suggesting efficacy of fecal microbiota transplant (FMT) in animal models and humans for the treatment of obesity and its associated metabolic disorders. PMID- 27698620 TI - The Hoops, Hopes, and Hypes of Human Microbiome Research. AB - Recent developments in sequencing methods and bioinformatics analysis tools have greatly enabled the culture-independent analysis of complex microbial communities associated with environmental samples, plants, and animals. This has led to a spectacular increase in the number of studies on both membership and functionalities of these hitherto invisible worlds, in particular those of the human microbiome. The wide variety in available microbiome tools and platforms can be overwhelming, and making sound conclusions from scientific research can be challenging. Here, I will review 1) the methodological and analytic hoops a good microbiome study has to jump through, including DNA extraction and choice of bioinformatics tools, 2) the hopes this field has generated for diseases such as autism and inflammatory bowel diseases, and 3) some of the hypes that it has created, e.g., by confusing correlation and causation, and the recent pseudoscientific commercialization of microbiome research. PMID- 27698623 TI - Striking a Balance with Help from our Little Friends - How the Gut Microbiota Contributes to Immune Homeostasis. AB - The trillions of microbes that inhabit the human gut (the microbiota) together with the host comprise a complex ecosystem, and like any ecosystem, health relies on stability and balance. Some of the most important members of the human microbiota are those that help maintain this balance via modulation of the host immune system. Gut microbes, through both molecular factors (such as capsular components) and by-products of their metabolism (such as Short Chain Fatty Acids (SCFAs)), can influence both innate and adaptive components of the immune system, in ways that can drive both effector, and regulatory responses. Here we review how commensal microbes can specifically promote a dynamic balance of these immune responses in the mammalian gut. PMID- 27698624 TI - Integrative Therapies in Anxiety Treatment with Special Emphasis on the Gut Microbiome. AB - Over the past decade, research has shown that diet and gut health affects symptoms expressed in stress related disorders, depression, and anxiety through changes in the gut microbiota. Psycho-behavioral function and somatic health interaction have often been ignored in health care with resulting deficits in treatment quality and outcomes. While mental health care requires the professional training in counseling, psychotherapy and psychiatry, complimentary therapeutic strategies, such as attention to a nutritional and diverse diet and supplementation of probiotic foods, may be integrated alongside psychotherapy treatment models. Development of these alternative strategies is predicated on experimental evidence and diligent research on the biology of stress, fear, anxiety-related behaviors, and the gut-brain connection. This article provides a brief overview on biological markers of anxiety and the expanding nutritional literature relating to brain health and mental disorders. A case study demonstrates an example of a biopsychosocial approach integrating cognitive psychotherapy, dietary changes, and mindfulness activities, in treating symptoms of anxiety. This case study shows a possible treatment protocol to explore the efficacy of targeting the gut-brain-axis that may be used as an impetus for future controlled studies. PMID- 27698625 TI - Triggering of Carpal Tunnel Syndrome Symptoms in Patients Using Urban Public Transportation. AB - Background: Carpal tunnel syndrome (CTS) is the most common compressive neuropathy found in clinical practice. Recent studies evaluated which external factors could be involved in the CTS symptoms, including prolonged exposure to vibration, especially in the upper limb. This study investigated signs and symptoms in patients with CTS after using urban transport on (1) both upper limbs, (2) how long before these symptoms appear, and (3) the hands position or body reaction during the act of pressing the safety bars. Methods: The study was conducted from July 2012 to April 2013. A total of 205 (178 women and 27 men) patients were evaluated. CTS was diagnosed in 285 hands. All participants answered a questionnaire formulated by the authors. The questionnaire was applied by researchers who were single-blinded and not involved in the research. Results: Most of the participants (87%) were women, but there was no statistical significance in age between groups (women = 51.24 +/- 8.47 years, men = 51.10 +/- 6.52 years, P > .05). The symptoms appeared significantly in the first 15 minutes after boarding when compared with patients who had no symptoms during the journey. There was no difference between hands position along the journey and the onset of symptoms. Conclusions: The onset of symptoms in patients with CTS using urban public transportation most commonly occurred in the first 15 minutes after boarding. Public transport vibration seems to be, at least in part, directly related to the development of symptoms. Questionnaires for the assessment of paresthesia symptoms during the use of public transport may be useful for CTS diagnosis. PMID- 27698628 TI - Hand Surgeon Reporting of Tendon Rupture Following Distal Radius Volar Plating. AB - Background: Volar plate fixation with locked screws has become the preferred treatment of displaced distal radius fractures that cannot be managed nonoperatively. This treatment, however, is not without complication. The purpose of this study was to determine what percentage of hand surgeons, over a 12-month period, have experienced a tendon complication when using volar plates for the treatment of distal radius fractures. Methods: A total of 3022 hand surgeons were e-mailed a link to an online questionnaire regarding their observation and treatment of tendon injuries associated with volar plating of distal radius fractures. Responses were reported using descriptive statistics. Results: Of the 596 (20%) respondents, 199 (33%) surgeons reported encountering at least one flexor tendon injury after distal radius volar plating over the past year of practice. The flexor pollicis longus was the most commonly reported tendon injury (254, 75%). Palmaris longus grafting (118, 37%) and tendon transfer (114, 36%) were the most often reported treatments following this complication. A total of 216 respondents (36%) also encountered 324 cases of extensor tendon rupture after volar plating of distal radius fractures, with tendon transfer (88%) being the preferred treatment option. Conclusions: Both flexor and extensor tendon ruptures can be seen after volar plating of distal radius fractures. Surgeons should be aware of these complications. Critical assessment of hardware position at the time of index procedure is recommended to avoid complications. Long-term studies are needed to standardize approaches to managing tendon rupture following volar plating of distal radius fractures. PMID- 27698626 TI - Symbrachydactyly. AB - Background: Symbrachydactyly is a unilateral congenital hand malformation characterized by failure of formation of fingers and the presence of rudimentary digit nubbins. The management is variable and are investigated in this review. Methods: A detailed review of the literature was compiled into succinct clinically relevant categories. Results: Etiology, classification, non-surgical management, surgical intervention, and patient oriented outcomes are discussed. Conclusions: All interventions should prioritize realistic, evidence-supported appearance and functional gains. Studies of the baseline function and quality of life of children with symbrachydactyly would allow surgeons to better understand functional changes associated with various interventions and would help surgeons and parents to make the best treatment decisions. PMID- 27698627 TI - Carpal Coalitions and Metacarpal Synostoses: A Review. AB - Background: Carpal coalition and metacarpal synostosis are uncommon congenital anomalies of the carpus and hand. Methods: A comprehensive review of the literature was performed to help guide surgical and non-surgical treatment of carpal coalition and metacarpal synostosis. Results: The embryology, epidemiology, medical and surgical management, and associated outcomes are detailed. Conclusions: Most patients with these disorders will likely benefit from conservative measures. Surgery should be considered in patients with pain and limitations in wrist and hand function. PMID- 27698629 TI - Malignant Glomus Tumors of the Hand. AB - Background: Glomus tumors are uncommon vascular tumors of the hand. Malignant glomus tumors, known as glomangiosarcomas, are very rare and offer management challenges. Methods: A review of the diagnosis and treatment of malignant glomus tumors is presented in along with a report of the largest malignant glomus tumor of the hand to date. Results: The review illustrates the management of glomangiosarcomas. Only 6 previous such cases have been reported. Conclusion: The rare nature of malignant glomus tumors mandates case presentation and longitudinal analysis to help guide surgical management an optimize outcomes. PMID- 27698631 TI - The Association of Complementary Health Approaches With Mood and Coping Strategies Among Orthopedic Patients. AB - Background: Variation in pain intensity and magnitude of disability among patients with musculoskeletal illness is largely accounted for by variations in symptoms of depression, catastrophic thinking, and heightened illness concern. It is possible that patients with greater stress, distress, and less effective coping strategies might be more likely to seek the use of Complementary Health Approaches (CHA). This study addressed the primary null hypothesis that there are no demographic, illness-related, or psychological factors associated with CHA use among patients with upper extremity illness. Methods: A cohort of 170 patients completed a web-based Complementary and Alternative Medicine (CAM) questionnaire the Patient Reported Outcomes Measurement Information System (PROMIS) Depression and Pain Interference questionnaires. We evaluated differences between patients who sought CAM treatment regarding the PROMIS Pain Interference and PROMIS Depression scores. Ninety-four patients (56%) use or plan to use CAM treatment. A CAM provider was consulted by 61 patients (37%): most commonly a massage therapist (30/61), chiropractor (26/61), or acupuncturist (14/61). Results: In bivariate analysis patients who sought CAM reported greater average PROMIS Pain Interference than those who did not. In multivariable logistic regression, CAM use was associated with a higher Pain Interference Score and the specific surgeon. Conclusion: In conclusion, CHA use is prevalent amongst orthopaedic patients and associated with less effective coping strategies. Orthopaedic surgeons might consider asking patients about CHA use and determining whether those patients are interested in cognitive behavioral therapy. PMID- 27698630 TI - Longitudinal Outcomes Following a Randomized Controlled Trial of Dynamic Splint Stretching for Carpal Tunnel Syndrome. AB - Background: The incidence of carpal tunnel syndrome (CTS) is 48 million patients in the United States. The purpose of this longitudinal study was to determine whether Dynasplint stretching (immediately after diagnosis) had an effect on a patient's decision to seek surgical treatment for CTS. Methods: Fifty patients (10 men, 40 women, mean age 51.2 +/- 12 years) were recruited for this randomized, controlled, longitudinal trial. Patients were diagnosed with CTS by physical examination and nerve conduction studies. The intervention used was Dynasplint stretching that delivered a prolonged duration of low load stretching. Patients who were randomly chosen for the Experimental category wore the device for two 30-minute sessions per day with regular increases in splint tension for 60 days. Control patients received nonsteroidal anti-inflammatory medication plus instructions on daily home stretching. Results: The final, longitudinal outcome showed a 72% reduction in surgery chosen by the experimental group (n = 25), compared with 38% reduction for control patients (n = 25). Conclusions: Immediate treatment with Dynasplint stretching showed a 2 to 1 reduction in surgery, with abundant financial savings. PMID- 27698633 TI - Efficient Construction of Volar Wrist Splints: A Biomechanical Study Comparing Splints of Different Material, Thickness, and Design. AB - Background: The aim was to test the null hypothesis that splint material, thickness, or longitudinal ridging does not affect the strength of a wrist splint. Methods: Ten splints were made according to each of 7 different splint designs (resulting in 7 groups of 10 splints each). All splints were the same length and were molded to approximate the contour of the volar hand, wrist, and forearm with the wrist in neutral. Three groups consisted of plaster splints of different thicknesses (8, 10, and 12 ply). Three additional groups included splints of the same thicknesses but with a longitudinal ridge. A single group was constructed from prefabricated fiberglass splinting material and did not involve a longitudinal ridge. Five splints in each group were subjected to 3-point bending mimicking flexion of the wrist and 5 were subjected to a 3-point bend mimicking wrist extension. Splints were loaded to failure using a servohydraulic load frame. Analysis of variance was used to compare splints. Results: Among the plaster splints, more layers of material and longitudinal ridging increased splint strength. Ridged 8-ply plaster splints exceeded the strength of nonridged 10-ply plaster splints. Ridged 8-ply plaster splints were similar in strength to fiberglass splints. Conclusions: The 8-ply ridged plaster splints may be a lighter, effective, and cheaper alternative to more common splint designs. PMID- 27698632 TI - Long-Term Outcomes of Primary Repair of Chronic Thumb Ulnar Collateral Ligament Injuries. AB - Background: The purpose of this study is to evaluate long-term outcomes of ligamentous repair rather than reconstruction for chronic thumb ulnar collateral ligament (UCL) injuries. Methods: Patients at least 15-years status-post repair of a chronic (greater than 6 weeks) UCL tear were contacted for clinical evaluation, radiographs, and postoperative outcome questionnaires, including the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, visual analog scale (VAS) pain scale, and study-specific questions. Twelve of 21 (57%) living patients were available for long-term, greater than 15-year follow-up (average 24.5 years, range 16.9-35.6). Results: Eighty-eight percent of patients had some degree of osteoarthritis. Increased age at the time of injury and higher DASH scores were correlated with increased grades of the thumb metacarpophalangeal osteoarthritis. Delay to treatment and VAS pain scores had no correlation with radiographic findings. Conclusions: Repair of a chronic UCL injury with available local tissue appears to be a reasonable alternative to ligament reconstruction, resulting in durable long-term outcomes despite the majority of patients progressing to osteoarthritis. PMID- 27698634 TI - Linking of the American Academy of Orthopaedic Surgeons Distal Radius Fracture Clinical Practice Guidelines to the International Classification of Functioning, Disability, and Health; International Classification of Diseases; and ICF Core Sets for Hand Conditions. AB - Background: American Academy of Orthopaedic Surgeons (AAOS) distal radius fracture (DRF) clinical practice guidelines (CPG) are readily available to clinicians, patients, and policymakers. International Classification of Functioning, Disability, and Health (ICF) provides a framework for describing the impact of health conditions. The International Classification of Diseases-10th Revision (ICD-10) is a classification system to classify health conditions as specific disease or disorders. The aim of this study is to analyze and describe the scope and focus of the AAOS DRF CPG using the ICF and ICD-10 as a basis for content analysis, and to compare the content of the CPG with the ICF hand core sets as the reference standard. Methods: Established linking rules were used by 2 independent raters to analyze the 29 recommendations of the AAOS DRF CPG. ICD-10 codes were assigned in the same process. Summary linkage statistics were used to describe the results for ICF and the hand core sets. Results: Among the 29 recommendations of the AAOS DRF CPG, 5 meaningful concepts were linked to the ICF codes. Of these, 5 codes appeared on the comprehensive ICF core set and only 3 codes appeared in the brief ICF core set, and 7 conditions were covered in ICD-10 codes. Conclusions: The AAOS DRF CPG focuses on surgical interventions and has minimal linkage to the constructs of the ICD-10 and ICF. It does not address activity or participation (disability), and is not well linked to key concepts relevant to hand conditions. PMID- 27698635 TI - Distal Inside-Out Epineural Sliding Technique to Repair Segmental Nerve Defects. AB - Background: The repair of a segmental peripheral nerve injury is a clinical challenge. Several studies have been performed to determine superior methods for overcoming nerve gaps. The purpose of this study was to investigate if the inside out slided epineurium of the distal segment of an injured nerve can serve as a conduit to bridge a short nerve defect (10 mm). Methods: Nineteen sciatic nerves in Sprague-Dawley rats were transected, and a 10-mm gap was left between the ends. A section of distal epineurium was pulled inside out to bridge the gap. Walking track analysis was performed, and the sciatic function index (SFI) was calculated. Wet muscle mass and withdrawal reflex were measured. The density of axon fibers at different levels of repaired nerves was determined, and histological analysis was performed at 16 weeks. Results: The mean SFI improved from -81.0 at 4 weeks to 36.3 at 16 weeks. The axon densities showed regeneration through the epineural tube, and 5 of the rats demonstrated a withdrawal reflex. The weight of the tibialis anterior muscle of the injured limb at 16 weeks was 59% that of the uninjured side. Conclusions: The distal epineural sheath tube provided a size-matched conduit between the nerve stumps, with no histological donor-site morbidity. Histologically, regeneration occurred through the epineural tube without neuroma formation, and functional recovery was comparable to that of previous studies of nerve repair techniques. Technique may be an addition to the armamentarium of tools used to treat segmental nerve defects. PMID- 27698637 TI - Extensor Indicis Proprius Tenodesis to Correct Finger Ulnar Drift Deformity in Rheumatoid Arthritis. AB - Background: The most frequent deformity of the hand occurring in patients with RA affects the metacarpophalangeal (MCP) joint and it is characterized by a volar subluxation of the proximal phalanges and ulnar drift of the fingers. Methods: The Extensor Indicis Proprius (EIP) tenodesis for correction of ulnar deviation of fingers (II to V) was performed in 10 hands (40 fingers and 5 patients). Results: There was complete correction of the subluxation or dislocation and almost complete correction of the ulnar drift of the metacarpophalangeal joints at the initial postoperative evaluation (three to four months after surgery). However, at final evaluation (eight to twelve months after the operation), all of the digits had some recurrence of ulnar deviation. Conclusion: The EIP tenodesis provides a correct forces vector to maintain the fingers in proper alignment following correction of ulnar deviation. PMID- 27698636 TI - A Cross-Sectional Study of Musculoskeletal Health Literacy in Patients With Carpal Tunnel Syndrome. AB - Background: Approximately 33% of Americans have inadequate health literacy, which is associated with infrequent use of preventative services, increased hospitalization and use of emergency care, and worse control of chronic diseases. In this study, the Literacy in Musculoskeletal Problems (LiMP) questionnaire was used to evaluate the prevalence of limited musculoskeletal literacy in patients undergoing carpal tunnel release (CTR), as these individuals may be at increased risk of inferior outcomes. Methods: This cross-sectional study included individuals older than or equal to 18 years of age who were scheduled for elective CTR. Participants completed a demographic survey and the LiMP questionnaire during their preoperative office visit. The prevalence of limited health literacy was determined, with chi-square analysis used to determine the influence of demographic parameters. Results: The mean LiMP score was 6 +/- 1.40. Limited musculoskeletal literacy was seen in 34% of participants (22/65). Analysis identified race (Caucasian), gender (female), higher education levels (>=college), current or prior employment in a health care field, and a prior physician visit for a non-carpal tunnel musculoskeletal complaint as being associated with higher literacy rates. Conclusions: Approximately one-third of patients scheduled for elective CTR have limited musculoskeletal literacy and may lack the necessary skills required for making informed decisions regarding their care. This is concerning, as CTR is performed in the United States on roughly 500 000 individuals annually, at an estimated cost of 2 billion dollars. The identification of those most at risk is thus crucial, and will facilitate the development of education campaigns and interventions geared toward those who are most vulnerable. PMID- 27698638 TI - Results of Operative Intervention for Finger Stiffness After Fractures of the Hand. AB - Background: Posttraumatic finger stiffness can occur as a result of hand fractures. The purpose was to assess and quantify the improvement in range of motion (ROM) after surgical management of the stiff finger in patients who developed loss of motion following treatment for a metacarpal or phalangeal fracture. In addition, an aim was to identify possible risk factors for suboptimal improvement in ROM postoperatively. Methods: A retrospective review was performed on 18 patients who underwent surgery to improve finger stiffness following metacarpal or phalangeal fracture. Demographic data including age, initial diagnosis and treatment, health history, and worker's compensation status were collected. We determined the number of specific procedures performed at the time of surgery, the number of days between surgical release and initiation of therapy, and the total active motion (TAM) prior to surgical release and at the patient's last follow-up. Results: Mean TAM improved from 150 degrees preoperatively (range 60 degrees -241 degrees ) to 191 degrees postoperatively (range 61 degrees -271 degrees ). Most patients required multiple anatomic structures released concomitantly, with an average of 3.1. Patients who started physical therapy within 7 days of the release improved by 59 degrees , whereas those who started physical therapy after 7 days (average 11.5 days) lost 19 degrees of motion. Patients who had filed a worker's compensation claim improved an average of 9 degrees , whereas nonworker's compensation patients improved an average of 58 degrees . Degree of TAM improvement had a weak correlation with patient age or preoperative TAM. Conclusions: Surgical release for stiff fingers following hand fractures can offer modest improvements in ROM in some patients. Although the overall increase in motion as a result of these operations is generally limited, functional improvement can be obtained. Delay in initiating physical therapy is a risk factor for persistent or worsened stiffness. Patients involved in worker's compensation claims demonstrated significantly lower TAM improvement after surgical intervention. PMID- 27698639 TI - Geographic and Age-Based Variations in Medicare Reimbursement Among ASSH Members. AB - Background: The purpose of this study was to investigate how American Society for Surgery of the Hand (ASSH) members' Medicare reimbursement depends on their geographical location and number of years in practice. Methods: Demographic data for surgeons who were active members of the ASSH in 2012 were obtained using information publicly available through the US Centers for Medicare and Medicaid Services (CMS). "Hand-surgeons-per-capita" and average reimbursement per surgeon were calculated for each state. Regression analysis was performed to determine a relationship between (1) each state's average reimbursement versus the number of ASSH members in that state, (2) average reimbursement versus number of hand surgeons per capita, and (3) total reimbursement from Medicare versus number of years in practice. Analysis of variance (ANOVA) was used to detect a difference in reimbursement based on categorical range of years as an ASSH member. Results: A total of 1667 ASSH members satisfied inclusion in this study. Although there was significant variation among states' average reimbursement, reimbursement was not significantly correlated with the state's hand surgeons per capita or total number of hand surgeons in that given state. Correlation between years as an ASSH member and average reimbursement was significant but non-linear; the highest reimbursements were seen in surgeons who had been ASSH members from 8 to 20 years. Conclusions: Peak reimbursement from Medicare for ASSH members appears to be related to the time of surgeons' peak operative volume, rather than any age based bias for or against treating Medicare beneficiaries. In addition, though geographic variation in reimbursement does exist, this does not appear to correlate with density or availability of hand surgeons. PMID- 27698640 TI - Baseline Characteristics of the Median Nerve on Ultrasound Examination. AB - Background: Previous studies using ultrasound for diagnosis of carpal tunnel syndrome have reported on relatively small series of patients, leading to large standard deviations and/or confidence intervals for the mean cross-sectional area of the median nerve. The purpose of this study is to define the CSA of the median nerve in a large cohort of patients. Methods: Patients (n = 175) without history of carpal tunnel release were recruited. All participants were evaluated using the Carpal Tunnel Syndrome-6 questionnaire, a validated clinical diagnostic tool, with a score of 12 or greater considered positive for CTS. Ultrasound examination was performed on both wrists of all participants using a 13-6 MHz linear array transducer. Results: The mean median nerve CSA was significantly larger (P < .001) for patients with a positive (mean = 11.16, SD = 2.51) versus negative CTS 6 result (mean = 6.91, SD = 2.06). There was a significant correlation (.527, P < .001, n = 349) between CSA and CTS-6 score. Logistic regression analysis determined that a CSA of 10 mm2 optimized sensitivity and specificity at 80% and 88%, respectively. Accuracy was 87.9%. Conclusions: A significant difference in mean CSA was found between patients with and without CTS. Median nerve CSA showed a statistically significant positive correlation with CTS-6. Similar to prior studies, a CSA of 10 mm2 was determined to be the optimal cutoff. In this large series of patients, ultrasound was a sensitive, specific, and accurate test for confirmation of a clinical diagnosis of CTS. PMID- 27698642 TI - Impact of Long Flexor Versus Intrinsic Dominance in the Generation of Arc of Finger Flexion. AB - Background: Finger flexion is a composite movement involving both long flexors and intrinsic hand muscles. Previous studies have characterized this but have not investigated differences within the normal population. Were discrete finger motion patterns identified, this could guide rehabilitation programs following flexor tendon surgery. Methods: Twelve volunteers repeatedly flexed and extended at a comfortable speed, resting their hand on a horizontal surface. Video was recorded perpendicular to the little finger flexion plane, and the little finger tip position was identified frame by frame to create a composite curve. Its highest point was noted, and the horizontal distance was measured from this point to the palmar digital crease (DeltaXH). Results: In addition, 2 investigators independently reviewed frame-by-frame images and allocated subjects into groups based on the motion pattern. DeltaXH demonstrated 2 clusters within our study population, and there was a statistically significant (P < .036) difference between groups. Conclusions: This study demonstrated that qualitative and quantitative differences exist in flexion curves between individuals. PMID- 27698641 TI - The Radial Artery's Sacrifice in the Chinese Flap Is Not Deleterious to Patients. AB - Background: A widely discussed subject, albeit with few associated studies and publications, centers on whether sacrifice of the radial artery to perform the radial forearm flap (RFF) is deleterious to the patient. The objective of this study was to assess, by questionnaire, the complications reported at the donor site, particularly those related to sacrifice of the radial artery. Methods: During the 2014 Symposium of the Brazilian Society of Reconstructive Microsurgery, surgeons were asked to answer a questionnaire on RFF cases and complications. Results: Results were collected from hand and plastic surgeons. Regarding the opinion of respondents on the deleteriousness of sacrificing the radial artery, most answered negatively, that is, no deleterious effects reported. No statistically significant difference was found between the level of experience and opinion on whether sacrificing the radial artery was deleterious. Conclusions: Beyond performing some procedures and following evolution within a specific service, it was decided to broaden the range of opinions and enlarge the casuistic by assessing the opinions of many specialists from the fields of hand surgery and plastic surgery. Data collected using the questionnaire were compared to determine the sequelae at the donor site and particularly whether sacrifice of the radial artery in RFF was deleterious to the patient. Although complaints at the donor site were frequently cited, no objective reports on morbidity following the sacrifice of the radial artery in RFF were provided. PMID- 27698643 TI - Foreign-Body Reaction and Osteolysis in Dorsal Lunate Dislocation Repair With Bioabsorbable Suture Anchor. AB - Background: In recent years the use of biodegradable suture anchors for treating tendon and ligament pathology in hand surgery became popular. These materials are biocompatible, radiolucent, and load sharing, as they incrementally transfer load to surrounding bone during the resorption process. Despite these numerous advantages, polyglycolic (PGA) and poly-L-lactic acid (PLLA) have become a problem because of the potential risk for foreign body reactions. Methods: This article presents a case of an intraosseous foreign body reaction and massive osteolysis of the proximal carpal after dorsal lunate dislocation repair with bioabsorbable suture anchors. Results: Because of the persistent pain and the decreased strength, a proximal row carpectomy was performed 12-months after the initial trauma. Conclusions: Hand surgeons should be aware of the possibility of a late foreign body reaction, that could be especially severe in carpal bones. PMID- 27698644 TI - Proximal Interphalangeal Joint Fibromatosis After Pyrocarbon Implant Insertion: A Case Report. AB - Background: Pyrocarbon implants represent an increasingly popular method to treat proximal interphalangeal joint dysfunction. To this point, no association has been shown between pyrocarbon biomaterials and fibromatosis. We present a potentially serious and destructive complication associated with pyrocarbon arthroplasty. Methods: We demonstrate a clinical case involving pyrocarbon arthroplasty and subsequent fibromatosis development in an otherwise healthy 23 year-old female. To present this association, we illustrate the diagnostic workup involved in a rapidly expanding soft tissue mass of the hand and explain the appropriate treatment. Results: Pyrocarbon arthroplasty was associated with development of locally destructive fibromatosis confirmed by histopathological examination. Treatment involved wide resection with preservation of local structures. Conclusion: We describe the first association between fibromatosis and pyrocarbon biomaterial. Due to fibromatosis destructive effects, clinicians should be aware of potential complications associated with these materials and know how to accurately diagnose and treat these lesions. PMID- 27698646 TI - Pleomorphic Hyalinizing Angiectatic Tumor Arising in the Hand: A Case Report. AB - Background: Background: Pleomorphic hyalinizing angiectatic tumors (PHATs) are extremely rare, non-metastasizing tumors of uncertain origin that are typically seen in the lower extremities. To date, it is estimated that less than 100 cases have been reported worldwide since first described in 1996. Methods: The case of a 35-year-old male with a several-year history of a dorsal hand mass is presented. Although the patient was initially asymptomatic, in the months prior to presentation, the patient complained of pain with power grasp and direct pressure over the mass. The patient underwent uncomplicated surgical excision, during which the mass was noted to be adherent to the underlying extensor tendons. Results: Immunopathology confirmed the mass to be PHAT. We believe this is the first documented case of this rare tumor occurring in the hand. Conclusions: History and epidemiology of PHAT are reviewed. Then, in the context of the presented case, pre-operative evaluation, surgical management, pathologic findings and post-operative follow-up are all discussed. PMID- 27698645 TI - Bilateral Legg-Calve-Perthes Disease and Kienbock's Disease in a Child With Factor V Leiden Thrombophilia: A Case Report. AB - Background: The etiology of multifocal osteonecrosis is not definitively known; however, hypercoagulable state is a very plausible cause. Methods: We present an unusual case of a 12-year-old boy with a history of Legg-Calve-Perthes disease presenting with right wrist pain who was subsequently diagnosed with Kienbock's disease. The finding of multifocal osteonecrosis prompted testing for a hypercoagulable state that was positive for Factor V Leiden thrombophilia. A thorough literature review using Medline database was conducted to investigate associations between inherited hypercoagulable states and multifocal osteonecrosis. Results: Our literature review identified 2 similar cases of multifocal osteonecrosis associated with a hypercoagulable disorder in adult patients. There were no reports among the pediatric patient population. Meta analysis has demonstrated a potential link between Legg-Calve-Perthes disease and Factor V Leiden thrombophilia. Conclusions: This study offers further evidence to support the theory that multifocal osteonecrosis may be linked to a hypercoagulable state. Patients presenting with multifocal osteonecrosis should undergo screening for hypercoagulable states. Further investigation is needed to ascertain the potential benefit of prophylactic anticoagulation in patients with a known hypercoagulable state and multifocal osteonecrosis. PMID- 27698647 TI - Novel FeII and CoII Complexes of Natural Product Tryptanthrin: Synthesis and Binding with G-Quadruplex DNA. AB - Tryptanthrin is one of the most important members of indoloquinoline alkaloids. We obtained this alkaloid from Isatis. Two novel FeII and CoII complexes of tryptanthrin were first synthesized. Single-crystal X-ray diffraction analyses show that these complexes display distorted four-coordinated tetrahedron geometry via two heterocyclic nitrogen and oxygen atoms from tryptanthrin ligand. Binding with G-quadruplex DNA properties revealed that both complexes were found to exhibit significant interaction with G-quadruplex DNA. This study may potentially serve as the basis of future rational design of metal-based drugs from natural products that target the G-quadruplex DNA. PMID- 27698650 TI - Improved Neural Processing Efficiency in a Chronic Aphasia Patient Following Melodic Intonation Therapy: A Neuropsychological and Functional MRI Study. AB - Melodic intonation therapy (MIT) is a treatment program for the rehabilitation of aphasic patients with speech production disorders. We report a case of severe chronic non-fluent aphasia unresponsive to several years of conventional therapy that showed a marked improvement following intensive 9-day training on the Japanese version of MIT (MIT-J). The purpose of this study was to verify the efficacy of MIT-J by functional assessment and examine associated changes in neural processing by functional magnetic resonance imaging. MIT improved language output and auditory comprehension, and decreased the response time for picture naming. Following MIT-J, an area of the right hemisphere was less activated on correct naming trials than compared with before training but similarly activated on incorrect trials. These results suggest that the aphasic symptoms of our patient were improved by increased neural processing efficiency and a concomitant decrease in cognitive load.

PMID- 27698649 TI - Progressively Disrupted Intrinsic Functional Connectivity of Basolateral Amygdala in Very Early Alzheimer's Disease. AB - Very early Alzheimer's disease (AD) - i.e., AD at stages of mild cognitive impairment (MCI) and mild dementia - is characterized by progressive structural and neuropathologic changes, such as atrophy or tangle deposition in medial temporal lobes, including hippocampus and entorhinal cortex and also adjacent amygdala. While progressively disrupted intrinsic connectivity of hippocampus with other brain areas has been demonstrated by many studies, amygdala connectivity was rarely investigated in AD, notwithstanding its known relevance for emotion processing and mood disturbances, which are both important in early AD. Intrinsic functional connectivity (iFC) patterns of hippocampus and amygdala overlap in healthy persons. Thus, we hypothesized that increased alteration of iFC patterns along AD is not limited to the hippocampus but also concerns the amygdala, independent from atrophy. To address this hypothesis, we applied structural and functional resting-state MRI in healthy controls (CON, n = 33) and patients with AD in the stages of MCI (AD-MCI, n = 38) and mild dementia (AD-D, n = 36). Outcome measures were voxel-based morphometry (VBM) values and region-of interest-based iFC maps of basolateral amygdala, which has extended cortical connectivity. Amygdala VBM values were progressively reduced in patients (CON > AD-MCI and AD-D). Amygdala iFC was progressively reduced along impairment severity (CON > AD-MCI > AD-D), particularly for hippocampus, temporal lobes, and fronto-parietal areas. Notably, decreased iFC was independent of amygdala atrophy. Results demonstrate progressively impaired amygdala intrinsic connectivity in temporal and fronto-parietal lobes independent from increasing amygdala atrophy in very early AD. Data suggest that early AD disrupts intrinsic connectivity of medial temporal lobe key regions, including that of amygdala.

PMID- 27698651 TI - Diffusion Tensor Imaging Findings in Post-Concussion Syndrome Patients after Mild Traumatic Brain Injury: A Systematic Review. AB - OBJECTIVES: To review the evidence for the use of diffusion tensor imaging (DTI) parameters in the human brain as a diagnostic tool for and predictor of post concussion syndrome (PCS) after a mild traumatic brain injury (mTBI). DESIGN: Systematic review. DATA SOURCES: All relevant studies in AMED, Embase, MEDLINE, Ovid, PubMed, Scopus, and Web of Science through 20 May, 2016. STUDY SELECTION: Studies that analyze traditional DTI measures [fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD)] and the severity of PCS symptoms or the development of PCS in humans after an mTBI. DATA EXTRACTION: Population studied, patient source, mTBI diagnosis method, PCS diagnosis method, DTI values measured, significant findings, and correlation between DTI findings and PCS. DATA SYNTHESIS: Ten studies investigated correlations between DTI values and PCS symptom severity or between DTI values and the development of PCS in mTBI patients. Decreased FA and increased MD and RD were associated with the development and severity of PCS. AD was not found to change significantly. Brain regions found to have significant changes in DTI parameters varied from study to study, although the corpus callosum was most frequently cited as having abnormal DTI parameters in PCS patients. CONCLUSION: DTI abnormalities correlate with PCS incidence and symptom severity, as well as indicate an increased risk of developing PCS after mTBI. Abnormal DTI findings should prompt investigation of the syndrome to ensure optimal symptom management at the earliest stages. Currently, there is no consensus in the literature about the use of one DTI parameter in a specific region of the brain as a biomarker for PCS because no definite trends for DTI parameters in PCS subjects have been identified. Further research is required to establish a standard biomarker for PCS. PMID- 27698653 TI - Regulatory T Cells Are Dispensable for Tolerance to RBC Antigens. AB - Autoimmune hemolytic anemia (AIHA) occurs when pathogenic autoantibodies against red blood cell (RBC) antigens are generated. While the basic disease pathology of AIHA is well studied, the underlying mechanism(s) behind the failure in tolerance to RBC autoantigens are poorly understood. Thus, to investigate the tolerance mechanisms required for the establishment and maintenance of tolerance to RBC antigens, we developed a novel murine model. With this model, we evaluated the role of regulatory T cells (Tregs) in tolerance to RBC-specific antigens. Herein, we show that neither sustained depletion of Tregs nor immunization with RBC specific proteins in conjunction with Treg depletion led to RBC-specific autoantibody generation. Thus, these studies demonstrate that Tregs are not required to prevent autoantibodies to RBCs and suggest that other tolerance mechanisms are likely involved. PMID- 27698654 TI - Dexamethasone and Monophosphoryl Lipid A-Modulated Dendritic Cells Promote Antigen-Specific Tolerogenic Properties on Naive and Memory CD4+ T Cells. AB - Tolerogenic dendritic cells (DCs) are a promising tool to control T cell-mediated autoimmunity. Here, we evaluate the ability of dexamethasone-modulated and monophosphoryl lipid A (MPLA)-activated DCs [MPLA-tolerogenic DCs (tDCs)] to exert immunomodulatory effects on naive and memory CD4+ T cells in an antigen specific manner. For this purpose, MPLA-tDCs were loaded with purified protein derivative (PPD) as antigen and co-cultured with autologous naive or memory CD4+ T cells. Lymphocytes were re-challenged with autologous PPD-pulsed mature DCs (mDCs), evaluating proliferation and cytokine production by flow cytometry. On primed-naive CD4+ T cells, the expression of regulatory T cell markers was evaluated and their suppressive ability was assessed in autologous co-cultures with CD4+ effector T cells and PPD-pulsed mDCs. We detected that memory CD4+ T cells primed by MPLA-tDCs presented reduced proliferation and proinflammatory cytokine expression in response to PPD and were refractory to subsequent stimulation. Naive CD4+ T cells were instructed by MPLA-tDCs to be hyporesponsive to antigen-specific restimulation and to suppress the induction of T helper cell type 1 and 17 responses. In conclusion, MPLA-tDCs are able to modulate antigen specific responses of both naive and memory CD4+ T cells and might be a promising strategy to "turn off" self-reactive CD4+ effector T cells in autoimmunity. PMID- 27698655 TI - Neutrophil Integrins and Matrix Ligands and NET Release. AB - Neutrophils are motile and responsive to tissue injury and infection. As neutrophils emigrate from the bloodstream and migrate toward a site of affliction, they encounter the tissue extracellular matrix (ECM) and thereby engage integrins. Our laboratory studies the neutrophilic response to the fungal pathogen Candida albicans either in the filamentous state of the microbe or to the purified pathogen-associated molecular pattern, beta-glucan. We have gained an appreciation for the role of integrins in regulating the neutrophil anti Candida response and how the presence or absence of ECM can drive experimental outcome. The beta2 integrin CR3 (complement receptor 3; alphaMbeta2; Mac-1; CD11b/CD18) plays an important role in fungal recognition by its ability to bind beta-glucan at a unique lectin-like domain. The presence of ECM differentially regulates essential neutrophil anti-fungal functions, including chemotaxis, respiratory burst, homotypic aggregation, and the release of neutrophil extracellular traps (NETs). We have shown that NET release to C. albicans hyphae or immobilized beta-glucan occurs rapidly and without the requirement for respiratory burst on ECM. This is in contrast to the more frequently reported mechanisms of NETosis to other pathogens without the context of ECM, which occur after a prolonged lag period and require respiratory burst. As expected for an ECM-dependent phenotype, NETosis and other neutrophil functions are dependent on specific integrins. The focus of this review is the role of ECM ligation by neutrophil integrins as it pertains to host defense functions with an emphasis on lessons we have learned studying the anti-Candida response of human neutrophils. PMID- 27698658 TI - An Incremental Radial Basis Function Network Based on Information Granules and Its Application. AB - This paper is concerned with the design of an Incremental Radial Basis Function Network (IRBFN) by combining Linear Regression (LR) and local RBFN for the prediction of heating load and cooling load in residential buildings. Here the proposed IRBFN is designed by building a collection of information granules through Context-based Fuzzy C-Means (CFCM) clustering algorithm that is guided by the distribution of error of the linear part of the LR model. After adopting a construct of a LR as global model, refine it through local RBFN that captures remaining and more localized nonlinearities of the system to be considered. The experiments are performed on the estimation of energy performance of 768 diverse residential buildings. The experimental results revealed that the proposed IRBFN showed good performance in comparison to LR, the standard RBFN, RBFN with information granules, and Linguistic Model (LM). PMID- 27698656 TI - Neutrophil Extracellular Traps Go Viral. AB - Neutrophils are the most numerous immune cells. Their importance as the first line of defense against bacterial and fungal pathogens is well described. In contrast, the role of neutrophils in controlling viral infections is less clear. Bacterial and fungal pathogens can stimulate neutrophils extracellular traps (NETs) in a process called NETosis. Although NETosis has previously been described as a special form of programmed cell death, there are forms of NET production that do not end with the demise of neutrophils. As an end result of NETosis, genomic DNA complexed with microbicidal proteins is expelled from neutrophils. These structures can kill pathogens or at least prevent their local spread within host tissue. On the other hand, disproportionate NET formation can cause local or systemic damage. Only recently, it was recognized that viruses can also induce NETosis. In this review, we discuss the mechanisms by which NETs are produced in the context of viral infection and how this may contribute to both antiviral immunity and immunopathology. Finally, we shed light on viral immune evasion mechanisms targeting NETs. PMID- 27698659 TI - Fracture Mechanics Method for Word Embedding Generation of Neural Probabilistic Linguistic Model. AB - Word embedding, a lexical vector representation generated via the neural linguistic model (NLM), is empirically demonstrated to be appropriate for improvement of the performance of traditional language model. However, the supreme dimensionality that is inherent in NLM contributes to the problems of hyperparameters and long-time training in modeling. Here, we propose a force directed method to improve such problems for simplifying the generation of word embedding. In this framework, each word is assumed as a point in the real world; thus it can approximately simulate the physical movement following certain mechanics. To simulate the variation of meaning in phrases, we use the fracture mechanics to do the formation and breakdown of meaning combined by a 2-gram word group. With the experiments on the natural linguistic tasks of part-of-speech tagging, named entity recognition and semantic role labeling, the result demonstrated that the 2-dimensional word embedding can rival the word embeddings generated by classic NLMs, in terms of accuracy, recall, and text visualization. PMID- 27698657 TI - PPARgamma as a Novel Therapeutic Target in Lung Cancer. AB - Lung cancer is the leading cause of cancer-related death, with more than half the patients having advanced-stage disease at the time of initial diagnosis and thus facing a poor prognosis. This dire situation poses a need for new approaches in prevention and treatment. Peroxisome proliferator-activated receptor gamma (PPARgamma) is a ligand-activated transcription factor belonging to the nuclear hormone receptor superfamily. Its involvement in adipocyte differentiation and glucose and lipid homeostasis is well-recognized, but accumulating evidence now suggests that PPARgamma may also function as a tumor suppressor, inhibiting development of primary tumors and metastases in lung cancer and other malignancies. Besides having prodifferentiation, antiproliferative, and proapoptotic effects, PPARgamma agonists have been shown to prevent cancer cells from acquiring the migratory and invasive capabilities essential for successful metastasis. Angiogenesis and secretion of certain matrix metalloproteinases and extracellular matrix proteins within the tumor microenvironment are also regulated by PPARgamma. This review of the current literature highlights the potential of PPARgamma agonists as novel therapeutic modalities in lung cancer, either as monotherapy or in combination with standard cytotoxic chemotherapy. PMID- 27698660 TI - The Brainarium: An Interactive Immersive Tool for Brain Education, Art, and Neurotherapy. AB - Recent theoretical and technological advances in neuroimaging techniques now allow brain electrical activity to be recorded using affordable and user-friendly equipment for nonscientist end-users. An increasing number of educators and artists have begun using electroencephalogram (EEG) to control multimedia and live artistic contents. In this paper, we introduce a new concept based on brain computer interface (BCI) technologies: the Brainarium. The Brainarium is a new pedagogical and artistic tool, which can deliver and illustrate scientific knowledge, as well as a new framework for scientific exploration. The Brainarium consists of a portable planetarium device that is being used as brain metaphor. This is done by projecting multimedia content on the planetarium dome and displaying EEG data recorded from a subject in real time using Brain Machine Interface (BMI) technologies. The system has been demonstrated through several performances involving an interaction between the subject controlling the BMI, a musician, and the audience during series of exhibitions and workshops in schools. We report here feedback from 134 participants who filled questionnaires to rate their experiences. Our results show improved subjective learning compared to conventional methods, improved entertainment value, improved absorption into the material being presented, and little discomfort. PMID- 27698661 TI - A Forecasting Model for Feed Grain Demand Based on Combined Dynamic Model. AB - In order to improve the long-term prediction accuracy of feed grain demand, a dynamic forecast model of long-term feed grain demand is realized with joint multivariate regression model, of which the correlation between the feed grain demand and its influence factors is analyzed firstly; then the change trend of various factors that affect the feed grain demand is predicted by using ARIMA model. The simulation results show that the accuracy of proposed combined dynamic forecasting model is obviously higher than that of the grey system model. Thus, it indicates that the proposed algorithm is effective. PMID- 27698662 TI - A Novel Hybrid Clonal Selection Algorithm with Combinatorial Recombination and Modified Hypermutation Operators for Global Optimization. AB - Artificial immune system is one of the most recently introduced intelligence methods which was inspired by biological immune system. Most immune system inspired algorithms are based on the clonal selection principle, known as clonal selection algorithms (CSAs). When coping with complex optimization problems with the characteristics of multimodality, high dimension, rotation, and composition, the traditional CSAs often suffer from the premature convergence and unsatisfied accuracy. To address these concerning issues, a recombination operator inspired by the biological combinatorial recombination is proposed at first. The recombination operator could generate the promising candidate solution to enhance search ability of the CSA by fusing the information from random chosen parents. Furthermore, a modified hypermutation operator is introduced to construct more promising and efficient candidate solutions. A set of 16 common used benchmark functions are adopted to test the effectiveness and efficiency of the recombination and hypermutation operators. The comparisons with classic CSA, CSA with recombination operator (RCSA), and CSA with recombination and modified hypermutation operator (RHCSA) demonstrate that the proposed algorithm significantly improves the performance of classic CSA. Moreover, comparison with the state-of-the-art algorithms shows that the proposed algorithm is quite competitive. PMID- 27698663 TI - Fault Diagnosis for Analog Circuits by Using EEMD, Relative Entropy, and ELM. AB - This paper presents a novel fault diagnosis method for analog circuits using ensemble empirical mode decomposition (EEMD), relative entropy, and extreme learning machine (ELM). First, nominal and faulty response waveforms of a circuit are measured, respectively, and then are decomposed into intrinsic mode functions (IMFs) with the EEMD method. Second, through comparing the nominal IMFs with the faulty IMFs, kurtosis and relative entropy are calculated for each IMF. Next, a feature vector is obtained for each faulty circuit. Finally, an ELM classifier is trained with these feature vectors for fault diagnosis. Via validating with two benchmark circuits, results show that the proposed method is applicable for analog fault diagnosis with acceptable levels of accuracy and time cost. PMID- 27698664 TI - Colon Capsule Endoscopy: Review and Perspectives. AB - Colon capsule endoscopy utilizing PillCam COLON 2 capsule allows for visualization potentially of the entire colon and is currently approved for patients who cannot withstand the rigors of traditional optical colonoscopy (OC) and associated sedation as well as those that had an OC that was incomplete for technical reasons other than a poor preparation. We will then describe the prior experience and current status of colon capsule endoscopy. PMID- 27698665 TI - Evaluation and Verification of the Global Rapid Identification of Threats System for Infectious Diseases in Textual Data Sources. AB - The Global Rapid Identification of Threats System (GRITS) is a biosurveillance application that enables infectious disease analysts to monitor nontraditional information sources (e.g., social media, online news outlets, ProMED-mail reports, and blogs) for infectious disease threats. GRITS analyzes these textual data sources by identifying, extracting, and succinctly visualizing epidemiologic information and suggests potentially associated infectious diseases. This manuscript evaluates and verifies the diagnoses that GRITS performs and discusses novel aspects of the software package. Via GRITS' web interface, infectious disease analysts can examine dynamic visualizations of GRITS' analyses and explore historical infectious disease emergence events. The GRITS API can be used to continuously analyze information feeds, and the API enables GRITS technology to be easily incorporated into other biosurveillance systems. GRITS is a flexible tool that can be modified to conduct sophisticated medical report triaging, expanded to include customized alert systems, and tailored to address other biosurveillance needs. PMID- 27698666 TI - In Silico Analysis of Gene Expression Network Components Underlying Pigmentation Phenotypes in the Python Identified Evolutionarily Conserved Clusters of Transcription Factor Binding Sites. AB - Color variation provides the opportunity to investigate the genetic basis of evolution and selection. Reptiles are less studied than mammals. Comparative genomics approaches allow for knowledge gained in one species to be leveraged for use in another species. We describe a comparative vertebrate analysis of conserved regulatory modules in pythons aimed at assessing bioinformatics evidence that transcription factors important in mammalian pigmentation phenotypes may also be important in python pigmentation phenotypes. We identified 23 python orthologs of mammalian genes associated with variation in coat color phenotypes for which we assessed the extent of pairwise protein sequence identity between pythons and mouse, dog, horse, cow, chicken, anole lizard, and garter snake. We next identified a set of melanocyte/pigment associated transcription factors (CREB, FOXD3, LEF-1, MITF, POU3F2, and USF-1) that exhibit relatively conserved sequence similarity within their DNA binding regions across species based on orthologous alignments across multiple species. Finally, we identified 27 evolutionarily conserved clusters of transcription factor binding sites within ~200-nucleotide intervals of the 1500-nucleotide upstream regions of AIM1, DCT, MC1R, MITF, MLANA, OA1, PMEL, RAB27A, and TYR from Python bivittatus. Our results provide insight into pigment phenotypes in pythons. PMID- 27698667 TI - Myo-Inositol Safety in Pregnancy: From Preimplantation Development to Newborn Animals. AB - Myo-inositol (myo-Ins) has a physiological role in mammalian gametogenesis and embryonic development and a positive clinical impact on human medically assisted reproduction. We have previously shown that mouse embryo exposure to myo-Ins through preimplantation development in vitro increases proliferation activity and blastocyst production, representing an improvement in culture conditions. We have herein investigated biochemical mechanisms elicited by myo-Ins in preimplantation embryos and evaluated myo-Ins effects on postimplantation/postnatal development. To this end naturally fertilized embryos were cultured in vitro to blastocyst in the presence or absence of myo-Ins and analyzed for activation of the PKB/Akt pathway, known to modulate proliferation/survival cellular processes. In parallel, blastocyst-stage embryos were transferred into pseudopregnant females and allowed to develop to term and until weaning. Results obtained provide evidence that myo-Ins induces cellular pathways involving Akt and show that (a) exposure of preimplantation embryos to myo-Ins increases the number of blastocysts available for uterine transfer and of delivered animals and (b) the developmental patterns of mice obtained from embryos cultured in the presence or absence of myo-Ins, up to three weeks of age, overlap. These data further identify myo-Ins as a possibly important supplement for human preimplantation embryo culture in assisted reproduction technology. PMID- 27698669 TI - A Case of Malignant Biliary Obstruction with Severe Obesity Successfully Treated by Endoscopic Ultrasonography-Guided Biliary Drainage. AB - Here, we present a case of malignant biliary tract obstruction with severe obesity, which was successfully treated by endoscopic ultrasonography-guided biliary drainage (EUS-BD). A female patient in her sixties who had been undergoing chemotherapy for unresectable pancreatic head cancer was admitted to our institution for obstructive jaundice. She had diabetes mellitus, and her body mass index was 35.1 kg/m2. Initially, endoscopic retrograde cholangiopancreatography (ERCP) was performed, but bile duct cannulation was unsuccessful. Percutaneous transhepatic biliary drainage (PTBD) from the left hepatic biliary tree also failed. Although a second PTBD attempt from the right hepatic lobe was accomplished, biliary tract bleeding followed, and the catheter was dislodged. Consequently, EUS-BD (choledochoduodenostomy), followed by direct metallic stent placement, was performed as a third drainage method. Her postprocedural course was uneventful. Following discharge, she spent the rest of her life at home without recurrent jaundice or readmission. In cases of severe obesity, we consider EUS-BD, rather than PTBD, as the second drainage method of choice for distal malignant biliary obstruction when ERCP fails. PMID- 27698668 TI - Radioactive Merano SPA Treatment for Allergic Rhinitis Therapy. AB - Allergic rhinitis is a common nasal disorder with a high impact on quality of life, high social costs in therapies, and a natural development towards asthma. Pharmacological therapy is based on several genres of medications, of which intranasal corticosteroids are currently the most widespread. Thermal water treatment has traditionally been used as adjunctive treatment for chronic rhinitis and sinusitis. The present study was carried out to assess the clinical efficacy of nasal inhalation of radioactive oligomineral water vapours from the Merano hot spring and to compare it with the clinical efficacy of mometasone furoate nasal spray. A comparative prospective study was performed in 90 allergic patients treated at Merano hot springs: a group of 54 subjects treated with radioactive thermal oligomineral water and a control group of 36 subjects treated with mometasone nasal spray. Patients of both groups were assessed before and after treatment by Sino-Nasal Outcome Test questionnaire, active anterior rhinomanometry with flow and resistance monitoring, measurement of mucociliary transport time, and cytological examination of nasal brushing/scraping. The study showed that inhalation treatment with radioactive hydrofluoric thermal water for two weeks produces an objective clinical and cytological improvement in allergic patients, similar to that obtained with mometasone furoate nasal spray. PMID- 27698670 TI - A Giant Renal Vein Aneurysm in a Patient with Liver Cirrhosis. AB - We present an unusual case of a 40-year-old female patient with liver cirrhosis and diffuse abdominal pain. The imaging studies revealed a huge renal vein aneurysm. The patient refused any interventional management, despite the risk of possible rupture, and after a week of mild pain therapy, she was discharged. She was followed up closely, and after one year, she remains asymptomatic. Conservative management of such patients has been described before with success. However, open repair or percutaneous thrombosis of the aneurysm remains the indicated therapy, when vein patency is an issue for organ viability. PMID- 27698672 TI - Adipose-Derived Cells (Stromal Vascular Fraction) Transplanted for Orthopedical or Neurological Purposes: Are They Safe Enough? AB - Although mesenchymal stem cells are used in numerous clinical trials, the safety of their application is still a matter of concern. We have analysed the clinical results of the autologous adipose-derived stem cell treatment (stromal vascular fraction (SVF) containing adipose-derived stem cells, endothelial progenitors, and blood mononuclear cells) for orthopedic (cartilage, bone, tendon, or combined joint injuries) and neurologic (multiple sclerosis) diseases. Methods of adipose tissue collection, cell isolation and purification, and resulting cell numbers, viability, and morphology were considered, and patient's age, sex, disease type, and method of cell administration (cell numbers per single application, treatment numbers and frequency, and methods of cell implantation) were analysed and searched for the unwanted clinical effects. Results of cellular therapy were compared retrospectively to those obtained with conventional medication without SVF application. SVF transplantation was always the accessory treatment of patients receiving "standard routine" therapies of their diseases. Clinical experiments were approved by the Bioethical Medical Committees supervising the centers where patients were hospitalised. The conclusion of the study is that none of the treated patients developed any serious adverse event, and autologous mesenchymal stem (stromal) cell clinical application is a safe procedure resulting in some beneficial clinical effects (not analysed in this study). PMID- 27698671 TI - Review of Preclinical and Clinical Studies of Bone Marrow-Derived Cell Therapies for Intracerebral Hemorrhage. AB - Stroke is the second leading cause of mortality worldwide, causing millions of deaths annually, and is also a major cause of disability-adjusted life years. Hemorrhagic stroke accounts for approximately 10 to 27% of all cases and has a fatality rate of about 50% in the first 30 days, with limited treatment possibilities. In the past two decades, the therapeutic potential of bone marrow derived cells (particularly mesenchymal stem cells and mononuclear cells) has been intensively investigated in preclinical models of different neurological diseases, including models of intracerebral hemorrhage and subarachnoid hemorrhage. More recently, clinical studies, most of them small, unblinded, and nonrandomized, have suggested that the therapy with bone marrow-derived cells is safe and feasible in patients with ischemic or hemorrhagic stroke. This review discusses the available evidence on the use of bone marrow-derived cells to treat hemorrhagic strokes. Distinctive properties of animal studies are analyzed, including study design, cell dose, administration route, therapeutic time window, and possible mechanisms of action. Furthermore, clinical trials are also reviewed and discussed, with the objective of improving future studies in the field. PMID- 27698673 TI - Suboptimal Clinical Documentation in Young Children with Severe Obesity at Tertiary Care Centers. AB - Background and Objectives. The prevalence of severe obesity in children has doubled in the past decade. The objective of this study is to identify the clinical documentation of obesity in young children with a BMI >= 99th percentile at two large tertiary care pediatric hospitals. Methods. We used a standardized algorithm utilizing data from electronic health records to identify children with severe early onset obesity (BMI >= 99th percentile at age <6 years). We extracted descriptive terms and ICD-9 codes to evaluate documentation of obesity at Boston Children's Hospital and Cincinnati Children's Hospital and Medical Center between 2007 and 2014. Results. A total of 9887 visit records of 2588 children with severe early onset obesity were identified. Based on predefined criteria for documentation of obesity, 21.5% of children (13.5% of visits) had positive documentation, which varied by institution. Documentation in children first seen under 2 years of age was lower than in older children (15% versus 26%). Documentation was significantly higher in girls (29% versus 17%, p < 0.001), African American children (27% versus 19% in whites, p < 0.001), and the obesity focused specialty clinics (70% versus 15% in primary care and 9% in other subspecialty clinics, p < 0.001). Conclusions. There is significant opportunity for improvement in documentation of obesity in young children, even years after the 2007 AAP guidelines for management of obesity. PMID- 27698675 TI - Jin Fu Kang Oral Liquid Inhibits Lymphatic Endothelial Cells Formation and Migration. AB - Lung cancer is the leading cause of cancer-related deaths worldwide. Jin Fu Kang (JFK), an oral liquid prescription of Chinese herbal drugs, has been clinically available for the treatment of non-small cell lung cancer (NSCLC). Lymphangiogenesis is a primary event in the process of cancer development and metastasis, and the formation and migration of lymphatic endothelial cells (LECs) play a key role in the lymphangiogenesis. To assess the activity of stromal cell derived factor-1 (SDF-1) and the coeffect of SDF-1 and vascular endothelial growth factor-C (VEGF-C) on the formation and migration of LECs and clarify the inhibitory effects of JFK on the LECs, the LECs were differentiated from CD34+/VEGFR-3+ endothelial progenitor cells (EPCs), and JFK-containing serums were prepared from rats. SDF-1 and VEGF-C both induced the differentiation of CD34+/VEGFR-3+ EPCs towards LECs and enhanced the LECs migration. Couse of SDF-1 and VEGF-C displayed an additive effect on the LECs formation but not on their migration. JFK inhibited the formation and migration of LECs, and the inhibitory effects were most probably via regulation of the SDF-1/CXCR4 and VEGF-C/VEGFR-3 axes. The current finding suggested that JFK might inhibit NSCLC through antilymphangiogenesis and also provided a potential to discover antilymphangiogenesis agents from natural resources. PMID- 27698674 TI - Diabetic Osteoporosis: A Review of Its Traditional Chinese Medicinal Use and Clinical and Preclinical Research. AB - Aim. The incidence of diabetic osteoporosis (DOP) is increasing due to lack of effective management over the past few decades. This review aims to summarize traditional Chinese medicine (TCM) suitability in the pathogenesis and clinical and preclinical management of DOP. Methods. Literature sources used were from Medline (Pubmed), CNKI (China Knowledge Resource Integrated Database), and CSTJ (China Science and Technology Journal Database) online databases. For the consultation, keywords such as diabetic osteoporosis (DOP), TCM, clinical study, animal experiment, toxicity, and research progress were used in various combinations. Around 100 research papers and reviews were visited. Results. Liver spleen-kidney insufficiency may result in development of DOP. 18 clinical trials are identified to use TCM compound prescriptions for management of patients with DOP. TCM herbs and their active ingredients are effective in preventing the development of DOP in streptozotocin (STZ) and alloxan as well as STZ combined with ovariectomy insulted rats. Among them, most frequently used TCM herbs in clinical trials are Radix Astragali, Radix et Rhizoma Salviae Miltiorrhizae, Radix Rehmanniae Preparata, and Herba Epimedii. Some of TCM herbs also exhibit toxicities in clinical and preclinical research. Conclusions. TCM herbs may act as the novel sources of anti-DOP drugs by improving bone and glucolipid metabolisms. However, the pathogenesis of DOP and the material base of TCM herbs still merit further study. PMID- 27698676 TI - Hyeonggaeyeongyo-Tang for Treatment of Allergic and Nonallergic Rhinitis: A Prospective, Nonrandomized, Pre-Post Study. AB - Hyeonggaeyeongyo-tang (HYT) is an ancient formula of oriental medicine traditionally used to treat rhinitis; however, clinical evidence has not yet been established. The aim of this study was to investigate the short-term and long term efficacy and safety of HYT for chronic rhinitis. Adult subjects with chronic rhinitis symptoms were recruited. The subjects received HYT for 4 weeks and had follow-up period of 8 weeks. Any medicines used to treat nasal symptoms were not permitted during the study. The skin prick test was performed to distinguish the subjects with allergic rhinitis from those with nonallergic rhinitis. After treatment, the total nasal symptoms score and the Rhinoconjunctivitis Quality of Life Questionnaire score significantly improved in the whole subject group, in the allergic rhinitis group, and in the nonallergic rhinitis group, with no adverse events. This improvement lasted during a follow-up period of 8 weeks. Total IgE and eosinophil levels showed no significant difference after treatment in the allergic rhinitis group. HYT improved nasal symptoms and quality of life in patients with allergic rhinitis and nonallergic rhinitis. This is the first clinical study to evaluate the use of HYT to treat patients with rhinitis. This trial has been registered with the ClinicalTrials.gov Identifier NCT02477293. PMID- 27698678 TI - Exploring the Unexplored: Identifying Implicit and Indirect Descriptions of Biomedical Terminologies Based on Multifaceted Weighting Combinations. AB - In order to achieve relevant scholarly information from the biomedical databases, researchers generally use technical terms as queries such as proteins, genes, diseases, and other biomedical descriptors. However, the technical terms have limits as query terms because there are so many indirect and conceptual expressions denoting them in scientific literatures. Combinatorial weighting schemes are proposed as an initial approach to this problem, which utilize various indexing and weighting methods and their combinations. In the experiments based on the proposed system and previously constructed evaluation collection, this approach showed promising results in that one could continually locate new relevant expressions by combining the proposed weighting schemes. Furthermore, it could be ascertained that the most outperforming binary combinations of the weighting schemes, showing the inherent traits of the weighting schemes, could be complementary to each other and it is possible to find hidden relevant documents based on the proposed methods. PMID- 27698677 TI - Identification of the Metabolic Enzyme Involved Morusin Metabolism and Characterization of Its Metabolites by Ultraperformance Liquid Chromatography Quadrupole Time-of-Flight Mass Spectrometry (UPLC/Q-TOF-MS/MS). AB - Morusin, the important active component of a traditional Chinese medicine, Morus alba L., has been shown to exhibit many vital pharmacological activities. In this study, six recombinant CYP450 supersomes and liver microsomes were used to perform metabolic studies. Chemical inhibition studies and screening assays with recombinant human cytochrome P450s were also used to characterize the CYP450 isoforms involved in morusin metabolism. The morusin metabolites identified varied greatly among different species. Eight metabolites of morusin were detected in the liver microsomes from pigs (PLMs), rats (RLMs), and monkeys (MLMs) by LC-MS/MS and six metabolites were detected in the liver microsomes from humans (HLMs), rabbits (RAMs), and dogs (DLMs). Four metabolites (M1, M2, M5, and M7) were found in all species and hydroxylation was the major metabolic transformation. CYP1A2, CYP2C9, CYP2D6, CYP2E1, CYP3A4, and CYP2C19 contributed differently to the metabolism of morusin. Compared to other CYP450 isoforms, CYP3A4 played the most significant role in the metabolism of morusin in human liver microsomes. These results are significant to better understand the metabolic behaviors of morusin among various species. PMID- 27698679 TI - Huntington's disease: Molecular basis of pathology and status of current therapeutic approaches. AB - Huntington's disease (HD) is a frequent and incurable hereditary neurodegenerative disorder that impairs motor and cognitive functions. Mutations in huntingtin (HTT) protein, which is essential for neuronal development, lead to the development of HD. An increase in the number of CAG repeats within the HTT gene, which lead to an expansion of polyglutamine tract in the resulting mutated HTT protein, which is toxic, is the causative factor of HD. Although the molecular basis of HD is known, there is no known cure for this disease other than symptomatic relief treatment approaches. The toxicity of mutHTT appears to be more detrimental to striatal medium spiny neurons, which degenerate in this disease. Therapeutic strategies addressing a reduction in the mutHTT content at the transcriptional level using zinc finger proteins and at the translational level with RNA interference and antisense oligonucleotides or promoting the proteosomal degradation of mutHTT are being studied extensively in preclinical models and also to a limited extent in clinical trials. The post-translational modification of mutHTT is another possibility that is currently being investigated for drug development. In addition to the pharmacological approaches, several lines of evidence suggested the potential therapeutic use of stem cell therapy, in particular using the patient-derived induced pluripotent stem cells, to replace the lost striatal neurons. The multi-pronged clinical investigations currently underway may identify therapies and potentially improve the quality of life for the HD patients in future. PMID- 27698681 TI - Pain control by melatonin: Physiological and pharmacological effects. AB - Pain and anxiety are the most common neurological responses to many harmful or noxious stimuli and their management clinically is often challenging. Many of the frequently used morphine-based drugs, non-steroid anti-inflammatory drugs and acetaminophen, while efficient for treating pain, lead to patients suffering from several unwanted side effects. Melatonin, produced from the pineal body is a hormone of darkness, is involved in the control of circadian rhythms, and exerts a number of pharmacological effects. Melatonin mediates its actions through MT1/MT2 melatonin receptors on the cell membrane and also through RZR/ROR nuclear orphan receptors. Chronic pain syndromes are often associated with the desynchronization of circadian and biological rhythms, which also cause disturbances in the sleep-wake cycle. Melatonin-mediated analgesic effects seem to involve beta-endorphins, GABA receptor, opioid receptors and the nitric oxide arginine pathway. The effectiveness of melatonin as an analgesic and anxiolytic agent has been demonstrated in various animal models of pain and this led to the use of melatonin clinically in different pathological conditions and also in patients undergoing surgery. Melatonin was found to be effective in many of these cases as an anxiolytic and analgesic agent, indicating its clinical application.

AB - The epileptic state, or status epilepticus (SE), is the most serious situation manifested by individuals with epilepsy, and SE events can lead to neuronal damage. An understanding of the molecular, biochemical and physiopathological mechanisms involved in this type of neurological disease will enable the identification of specific central targets, through which novel agents may act and be useful as SE therapies. Currently, studies have focused on the association between oxidative stress and SE, the most severe epileptic condition. A number of these studies have suggested the use of antioxidant compounds as alternative therapies or adjuvant treatments for the epileptic state. PMID- 27698682 TI - Microwaves and Alzheimer's disease. AB - Alzheimer's diseases (AD) is the most common type of dementia and a neurodegenerative disease that occurs when the nerve cells in the brain die. The cause and treatment of AD remain unknown. However, AD is a disease that affects the brain, an organ that controls behavior. Accordingly, anything that can interact with the brain may affect this organ positively or negatively, thereby protecting or encouraging AD. In this regard, modern life encompasses microwaves for all issues including industrial, communications, medical and domestic tenders, and among all applications, the cell phone wave, which directly exposes the brain, continues to be the most used. Evidence suggests that microwaves may produce various biological effects on the central nervous system (CNS) and many arguments relay the possibility that microwaves may be involved in the pathophysiology of CNS disease, including AD. By contrast, previous studies have reported some beneficial cognitive effects and that microwaves may protect against cognitive impairment in AD. However, although many of the beneficial effects of microwaves are derived from animal models, but can easily be extrapolated to humans, whether microwaves cause AD is an important issue that is to be addressed in the current review.

AB - The present study aimed to evaluate the molecular mechanisms underlying combinatorial bone marrow stromal cell (BMSC) transplantation and chondroitinase ABC (Ch-ABC) therapy in a model of acellular nerve allograft (ANA) repair of the sciatic nerve gap in rats. Sprague Dawley rats (n=24) were used as nerve donors and Wistar rats (n=48) were randomly divided into the following groups: Group I, Dulbecco's modified Eagle's medium (DMEM) control group (ANA treated with DMEM only); Group II, Ch-ABC group (ANA treated with Ch-ABC only); Group III, BMSC group (ANA seeded with BMSCs only); Group IV, Ch-ABC + BMSCs group (Ch-ABC treated ANA then seeded with BMSCs). After 8 weeks, the expression of nerve growth factor, brain-derived neurotrophic factor and vascular endothelial growth factor in the regenerated tissues were detected by reverse transcription quantitative polymerase chain reaction and immunohistochemistry. Axonal regeneration, motor neuron protection and functional recovery were examined by immunohistochemistry, horseradish peroxidase retrograde neural tracing and electrophysiological and tibialis anterior muscle recovery analyses. It was observed that combination therapy enhances the growth response of the donor nerve locally as well as distally, at the level of the spinal cord motoneuron and the target muscle organ. This phenomenon is likely due to the propagation of retrograde and anterograde transport of growth signals sourced from the graft site. Collectively, growth improvement on the donor nerve, target muscle and motoneuron ultimately contribute to efficacious axonal regeneration and functional recovery. Thorough investigation of molecular peripheral nerve injury combinatorial strategies are required for the optimization of efficacious therapy and full functional recovery following ANA. PMID- 27698683 TI - DNA methylation in spermatogenesis and male infertility. AB - Infertility is a significant problem for human reproduction, with males and females equally affected. However, the molecular mechanisms underlying male infertility remain unclear. Spermatogenesis is a highly complex process involving mitotic cell division, meiosis cell division and spermiogenesis; during this period, unique and extensive chromatin and epigenetic modifications occur to bring about specific epigenetic profiles in spermatozoa. It has recently been suggested that the dysregulation of epigenetic modifications, in particular the methylation of sperm genomic DNA, may serve an important role in the development of numerous diseases. The present study is a comprehensive review on the topic of male infertility, aiming to elucidate the association between sperm genomic DNA methylation and poor semen quality in male infertility. In addition, the current status of the genetic and epigenetic determinants of spermatogenesis in humans is discussed. PMID- 27698685 TI - Targeting CRMP-4 by lentivirus-mediated RNA interference inhibits SW480 cell proliferation and colorectal cancer growth. AB - The aim of the present study was to investigate the expression level of collapsin response mediator protein 4 (CRMP-4) in human colorectal cancer (CRC) tissue and to evauluate its impact on SW480 cell proliferation, in addition to tumor growth in a mouse xenograft model. Clinical CRC tissue samples were collected to detect the CRMP-4 protein expression levels using western blot and immunohistochemistry analyses. A specific small interfering RNA sequence targeting the CRMP-4 gene (DPYSL3) was constructed and transfected into an SW480 cell line using a lentivirus vector to obtain a stable cell line with low expression of CRMP-4. The effectiveness of the interference was evaluated using western blot and reverse transcription-quantitative polymerase chain reaction, and the cell proliferation was determined using MTT and BrdU colorimetric methods. Tumor growth was assessed by subcutaneously inoculating the constructed cells into BALB/c nude mice. The protein expression levels of CRMP-4 were markedly increased in colon tumor tissue of the human samples. The proliferation of SW480 cells and the tumor growth rate in nude mice of the si-CPMR-4 group were evidently depressed compared with the si scramble group. Thus, the present results suggest that CRMP-4 may be involved in the pathogenesis of CRC. PMID- 27698686 TI - Osthole decreases renal ischemia-reperfusion injury by suppressing JAK2/STAT3 signaling activation. AB - Renal ischemia-reperfusion (I/R) injury is a major cause of acute kidney injury. The pathogenetic mechanisms underlying renal I/R injury involve inflammation, oxidative stress and apoptosis. Osthole is a coumarin derivative that exhibits potential anti-inflammatory activity. The aim of the present study was to investigate the effect of osthole in renal I/R injury and its underlying mechanism. Renal I/R injury was induced by clamping the left renal artery for 45 min followed by 24 h reperfusion with the contralateral nephrectomy. A total of 70 rats were randomly assigned to seven groups (n=10 per group): Sham; IRI; and osthole (0, 5, 10, 20 and 40 mg/kg) groups. Rats were administered intraperitoneally with osthole 45 min prior to renal ischemia. Serum and renal tissue were harvested 24 h after reperfusion. Renal function and histological changes were assessed. In addition, the mRNA and protein expression of tumor necrosis factor-alpha (TNF-alpha), interleukin-8 (IL-8) and interleukin-6 (IL-6) in renal tissue and serum were evaluated using quantitative polymerase chain reaction and ELISA assays, respectively. The protein expression levels of p65, p p65, janus kinase 2 (JAK2), p-JAK2, signal transducer and activator of transcription 3 (STAT3) and p-STAT3 were measured using western blot analysis. The results indicate that osthole pretreatment was able to significantly attenuate the renal dysfunction in a dose-dependent manner, histological changes and the expression of TNF-alpha, IL-8, IL-6, p-JAK2, p-STAT3 and p-p65 induced by renal I/R injury. However, neither osthole or I/R injury affected the expression p65, JAK2 and STAT3. Osthole pretreatment is able to reduce renal I/R injury by abrogating inflammation and the mechanism is partially involved in suppressing JAK2/STAT3 activation. Thus, osthole may be a novel practical strategy for the mitigation of renal I/R injury. PMID- 27698687 TI - Guided bone regeneration with local zoledronic acid and titanium barrier: An experimental study. AB - The aim of this study was to evaluate the effects on new bone formation of autogenous blood alone or in combination with zoledronic acid (ZA), a beta tricalcium phosphate (beta-TCP) graft or ZA plus a beta-TCP graft placed under titanium barriers. For this purpose, eight adult male New Zealand white rabbits were used in the study, each with four titanium barriers fixed around four sets of nine holes drilled in the calvarial bones. The study included four groups, each containing 2 rabbits. In the autogenous blood (AB group), only autogeneous blood was placed under the titanium barriers. The three experimental groups were the AB+ZA group, with autogenous blood plus ZA, the AB+beta-TCP group, with autogeneous blood plus a beta-TCP graft, and the AB+beta-TCP+ZA group, with autogeneous blood plus a beta-TCP graft and ZA mixture under the titanium barriers. The animals were sacrificed after 3 months. The amounts of new bone formation identified histomorphometrically were found to be higher after 3 months than at the time of surgery in all groups. The differences between the groups were examined with histomorphometric analysis, and statistically significant differences were identified at the end of the 3 months. The bone formation rate in the AB+beta-TCP+ZA group was determined to be significantly higher than that in the other groups (P<0.05). In the AB+ZA and AB+beta-TCP groups, the bone formation rate was determined to be significantly higher than that in the AB group (P<0.05). No statistically significant difference in bone formation rate was observed between the AB+beta-TCP and AB+ZA groups. Local ZA used with autogeneous blood and/or graft material appears to be a more effective method than the use of autogeneous blood or graft alone in bone augmentation executed with a titanium barrier. PMID- 27698688 TI - Specific clinical manifestations of Nocardia: A case report and literature review. AB - Nocardiosis is a rare bacterial infection of either the lungs (pulmonary) or body (systemic) that usually affects immunocompromised individuals. It is caused by Gram-positive, aerobic actinomycetes of the Nocardia genus. Multiple high-density sheet shadows in both lungs along with nodules or cavities are the most common presentations of nocardiosis, whereas a large pulmonary mass is considered to be rare. However, there is no specificity in the clinical manifestation of the disease. Therefore, isolation and identification of Nocardia strains is the only reliable diagnostic method. The present study describes the cases of two male patients of Asian descent with nocardiosis. Chest computed tomography scans showed a suspected tumor mass in both patients. Microscopic analysis and culturing of tissue samples obtained using a bronchoscope detected the presence of Nocardia wallacei. Neither patient showed signs of immunosuppression. The present study aimed to improve the understanding of lung nocardiosis and demonstrated that pulmonary nocardiosis should be suspected in the case of non immunocompromised patients with a large mass in the lung. Furthermore, a review of the literature on infection with Nocardia was conducted. PMID- 27698689 TI - Achievement of a target dose of bisoprolol may not be a preferred option for attenuating pressure overload-induced cardiac hypertrophy and fibrosis. AB - Bisoprolol is a drug that acts via the mechanism of specifically and selectively inhibiting the beta1-adrenoreceptor in cardiac myocytes, and provides a pure reduction of heart rate without changing other cardiac parameters. It has long been clinically used to treat cerebrovascular and cardiovascular illnesses. However, there is little information available on whether the role of bisoprolol in the attenuation of ventricular remodeling is dependent upon the achievement of a target dose, and whether it must be used as a preferred option. The aim of the present study was to clarify the underlying benefits of bisoprolol in the attenuation of pressure overload-induced cardiac hypertrophy and fibrosis at different doses. C57BL/6J male mice, aged 6-8 weeks, were treated with saline or one of three different doses of bisoprolol (Biso: 2.5, 5 or 10 mg/kg/day) for 8 weeks from day 1 after aortic banding (AB). A number of mice underwent sham surgery and were treated with saline or bisoprolol. The mice were randomly assigned into the sham (n=24) and AB (n=62) groups. The results revealed that bisoprolol had a protective role against the cardiac hypertrophy, fibrosis and dysfunction caused by AB. This was determined on the basis of heart/body and lung/body weight ratios and heart weight/tibia length ratios, as well as echocardiographic and hemodynamic parameters, histological analysis, and the gene expression levels of hypertrophic and fibrotic markers. The present study revealed that administration of bisoprolol for a long time period may enhance its role in the prevention of cardiac hypertrophy and fibrosis induced by AB, whereas no statistically significant difference was observed between the middle- and high doses. These observations indicated that the function of bisoprolol in protecting against cardiac hypertrophy, fibrosis and dysfunction is time-dependent. Furthermore, it is proposed that a middle dose of bisoprolol may be a better option for patients with cardiovascular illnesses, particularly those undertaking coronary artery bypass graft and cardiac pacemaker surgeries. These promising results require further clinical investigation. PMID- 27698690 TI - Effect of glycerol on sustained insulin release from PVA hydrogels and its application in diabetes therapy. AB - The present study aimed to investigate the effects of glycerol on the physical properties and release of an insulin-loaded polyvinyl alcohol (PVA) hydrogel film. The insulin-loaded hydrogel composite film was produced using the freeze thawing method, after which the in vitro swelling ratio, transmittance and insulin release, and the in vivo pharmacodynamics, of hydrogels containing various volumes of glycerol were investigated. The results demonstrated that the addition of glycerol reduced the swelling ratio and increased the softness of the PVA hydrogel film. An analysis of insulin release in vitro and of the hypoglycemic effects in rats demonstrated that the PVA hydrogel film had a sustained release of insulin and long-acting effect over 10 days. The results of the present study suggested that, as a hydrophilic plasticizer, glycerol was able to enhance the release of insulin in the early stage of release profile by enhancing the formation of water channels, although the total swelling ratio was decreased. Therefore, the insulin-loaded glycerol/PVA hydrogel film may be a promising sustained-release preparation for the treatment of diabetes. PMID- 27698691 TI - Overexpression of LRIG1 regulates PTEN via MAPK/MEK signaling pathway in esophageal squamous cell carcinoma. AB - The present study aimed to evaluate the role of leucine-rich repeats and immunoglobulin-like domain protein 1 (LRIG1) in the regulation of phosphatase and tensin homolog (PTEN) expression in esophageal carcinogenesis. LRIG1 was overexpressed in esophageal squamous cell carcinoma (ESCC) cell lines, and the effect of LRIG1 overexpression on the mRNA and protein expression levels of PTEN was evaluated by reverse transcription-quantitative polymerase chain reaction and western blotting. Furthermore, the effects of LRIG1 overexpression on the cell cycle distribution and apoptosis of ESCC cells were examined by flow cytometry. Various cell signaling pathway inhibitors were used to assess the effects of LRIG1 on downstream signaling in ESCC cell lines. In addition, the association between LRIG1 and PTEN expression was examined in 48 samples from patients with ESCC. LRIG1 overexpression was demonstrated to downregulate PTEN expression in ESCC cell lines, and promote their proliferation and inhibit apoptosis. In addition, LRIG1-mediated suppression of PTEN expression was inhibited by the U0126 inhibitor, which suggests that LRIG1 may inhibit the activation of PTEN signaling molecules by triggering the mitogen-activated protein kinase (MAPK)/MAPK kinase 1 (MEK) signaling pathway. In conclusion, the present study demonstrated that overexpression of LRIG1 significantly and adversely affected the survival of ESCC cells, and that the MAPK/MEK signaling pathway may be responsible for the repression of PTEN expression and function. PMID- 27698692 TI - Reversal effect and mechanism of Ginkgo biloba exocarp extracts in multidrug resistance of mice S180 tumor cells. AB - The aim of the present study was to investigate the reversal effect and its related mechanism of Ginkgo biloba exocarp extracts (GBEEs) in obtained multidrug resistance (MDR) of mice S180 tumor cells in vitro and in vivo. In order to simulate the clinical PFC [cis-dichlorodiamineplatinum, cisplatin (DDP) + fluorouracil (FU), FU+cyclophosphamide and cyclophosphamide] scheme, a gradually increasing dose was administered in a phased induction in order to induce S180 cells in vivo and to make them obtain multidrug resistance. The results in vitro demonstrated that GBEE could significantly increase the IC50 of DDP on S180 MDR cells, increase the accumulation of Adriamycin (ADR) and rhodamine 123 (Rho 123), and reduce the efflux of Rho 123 of S180 MDR cells. The results from the in vivo treatment with a combination of GBEE and DDP to S180 MDR ascites tumor in mice demonstrated that each dose of GBEE could effectively reverse the drug-resistance of S180 MDR cells to DDP in order to extend the survival time of mice with ascite tumors and inhibit tumor growth in solid tumor mice. In addition, GBEE effectively inhibited the expression of MDR-1 mRNA and multidrug resistance associated protein-1 mRNA in S180 MDR cells of ascites tumor in mice and improved the expression levels of cytokines, including interleukin (IL)-3, IL-18 and interferon-gamma in the blood serum of S180 MDR tumor-bearing mice. The present study showed that the mechanism of GBEE reversal of MDR may be associated with the inhibition of the functional activity of P-glycoprotein, the downregulation of drug resistance related gene expression of S180 MDR cells and the improvement of the production of related serum cytokines of S180 MDR tumor mice. PMID- 27698693 TI - ATP-induced cardioprotection against myocardial ischemia/reperfusion injury is mediated through the RISK pathway. AB - The aim of the present study was to examine the post-infarct acute effect of adenosine-5'-triphosphate (ATP) on myocardial infarction (MI) size as well as its precise molecular mechanism. Sixty New Zealand white male rabbits were exposed to 40 min of ischemia followed by 180 min of reperfusion. The rabbits were intravenously administered 3 mg/kg of ATP (ATP group) or saline (control group) immediately after reperfusion and maintained throughout the first 30 min. The wortmannin+ATP, PD-98059+ATP, and 5-hydroxydecanoic acid (5-HD) sodium salt+ATP groups were separately injected with wortmannin (0.6 mg/kg), PD-98059 (0.3 mg/kg), and 5-HD (5 mg/kg) 5 min prior to ATP administration. MI size was calculated as the percentage of the risk area in the left ventricle. Myocardial apoptosis was determined using a TUNEL assay. Western blot analysis was performed to examine the levels of protein kinase B (Akt)/p-Akt and extracellular signal regulated kinase (ERK)/p-ERK in the ischemic myocardium, 180 min after reperfusion. The infarct size was significantly smaller in the ATP group than in the control group (p<0.05). The infarct size-reducing effect of ATP was completely blocked by wortmannin, PD-98059 and 5-HD. Compared with the control group, cardiomyocyte apoptosis was significantly reduced in the ATP group, while this did not occur in the wortmannin+ATP, PD-98059+ATP and 5-HD+ATP groups. Western blot analysis revealed a higher myocardial expression of p-Akt and p-ERK 180 min following reperfusion in the ATP versus the control group. In conclusion, cardioprotection by postischemic ATP administration is mediated through activation of the reperfusion injury salvage kinase (RISK) pathway and opening of the mitochondrial ATP-dependent potassium channels. PMID- 27698694 TI - Diagnosing pyogenic, brucella and tuberculous spondylitis using histopathology and MRI: A retrospective study. AB - The present study examined the histopathological and magnetic resonance imaging (MRI) features of pyogenic, brucella and tuberculous spondylitis (PS, BS and TS, respectively). A total of 22 PS, 20 BS and 20 TS patients were included in the study. Histopathological examination was used to assess the lesion structure and composition, and the MRI observation identified the lesion location and signal features. The following histopathological and MRI features were identified significantly more in patients with PS than in patients with BS and TS: Predominant neutrophil infiltration, abnormal intervertebral disk signal, lesions on the ventral and lateral sides of the vertebral bodies, and thick and irregular abscess walls. The following histopathological and MRI features were identified significantly more in patients with BS than in patients with PS and TS: Predominant lymphocyte infiltration, new bone formation, epithelioid granuloma, lesions on the ventral sides of the vertebral bodies, no, or very mild, vertebral body deformation, no abnormal paraspinal soft tissue signal, no intraosseous or paraspinal abscesses, and thin and irregular abscess walls. The following histopathological and MRI features were identified significantly more in patients with TS than in patients with BS and PS: Sequestrum, Langerhans giant cells, caseous necrosis, lesions primarily in the thoracic region and on the lateral sides of the vertebral bodies, no obvious intervertebral disk damage, obvious vertebral body deformation, abnormal paraspinal soft tissue signal, intraosseous or paraspinal abscesses, and thin and smooth abscess walls. In conclusion, it can be suggested that these significant differences in histopathological and MRI features between the three different types of spondylitis may contribute towards the differential diagnosis of the diseases. PMID- 27698695 TI - Rare case of disseminated fusariosis in a young patient with graft vs. host disease following an allogeneic transplant. AB - Fusarium infection is a severe fungal infection caused by fungi of the genus Fusarium. It most commonly occurs in immunocompromised patients with malignant hematological comorbidities or secondary to hematopoietic stem cell transplant. The classical route of contamination is through inhalation but infection may also occur through contiguity with a skin lesion. This report describes the case of a 24-year-old woman who developed graft-vs.-host disease (GVHD) at 220 days after receiving an allogeneic stem cell transplant from a sibling donor for Hodgkin disease. On day 330 after transplant the patient presented with fever and several painful subcutaneous, tender, red nodules with ulcerative and necrotic features on the pelvic region and right leg, extensive glass infiltrative lesions in the lungs and pansinusitis; however, the patient did not have onychomycosis. Following skin biopsy, culture of cutaneous lesions, computed tomography (CT) scanning of the lungs and CT scanning and magnetic resonance imaging of facial sinuses the patient was diagnosed with disseminated Fusarium species infection. Despite intensive treatment with voriconazole, the patient succumbed with respiratory insufficiency on day 400 after transplant. This case is noteworthy because the patient did not have any additional risk associated with the allogeneic transplant; there was no transplant mismatch, no severe neutropenia and no prior clinical signs of onychomycosis. The association of skin lesions with GVHD lesions increased the initial immunosuppression and delayed diagnosis. PMID- 27698696 TI - Rhodiola rosea, folic acid, zinc and biotin (EndEP(r)) is able to improve ejaculatory control in patients affected by lifelong premature ejaculation: Results from a phase I-II study. AB - The therapeutic armamentarium currently available for the treatment of premature ejaculation (PE) is not highly satisfactory. However, phytotherapeutics appear to be an interesting option for PE management. The present study aimed to evaluate the tolerability and efficacy of a phytotherapeutic combination of Rhodiola rosea, folic acid, biotin and zinc (EndEP(r)) in the treatment of patients affected by lifelong PE. All patients affected by lifelong PE who were attending three Urological Institutions from July to December 2014 were enrolled in this prospective, multicentre, phase I-II study. All patients were assigned to receive oral tablets of EndEP(r) (one tablet per day) for 90 days. Clinical and instrumental analyses were carried out at enrolment and at the end of the study. International Prostatic Symptom Score (IPSS), International Index of Erectile Function (IIEF)-15, Premature Ejaculation Diagnostic Tool (PEDT) and Short Form (SF)-36 questionnaires were used. The intravaginal ejaculation latency time (IELT) for each event was also evaluated using the stop-watch technique. The main outcome measure was the difference from baseline in PEDT questionnaire and mean IELT at the end of the follow-up period. In total, 91 patients (mean age, 32.3+/ 5.6 years) were analysed. The baseline questionnaires mean scores were 1.1+/-1.6, 26.1+/-2.9, 15.3+/-3.4 and 98.2+/-0.5, for IPSS, IIEF-15, PEDT and SF-36, respectively. The mean IELT at baseline was 73.6+/-46.9s. At the follow-up examination (90 days after the start of treatment), no statistically significant differences were identified in terms of IPSS (1.4+/-1.5) or IIEF-15 (26.3+/-3.1) compared with the pre-treatment values (P=0.19 and P=0.64, respectively). A statistically significant difference was detected between the mean IELT at enrolment and after treatment (73.6+/-46.9 vs. 102.3+/-60.0; P<0.001) and SF-36 questionnaire (98.2+/-0.5 vs. 99.4+/-0.1; P<0.001). Fifty-five patients reported improvement in the control of ejaculation (60.4%). Very few adverse events were reported (4.4%). In conclusion, it was found that EndEP(r) significantly improved ejaculatory control and the quality of sexual life in patients affected by lifelong PE, with a very low rate of adverse events. PMID- 27698697 TI - Oncogenic role of epithelial cell transforming sequence 2 in lung adenocarcinoma cells. AB - Lung adenocarcinoma, which is the most common non-small cell lung cancer, is the leading cause of death from cancer worldwide. Epithelial cell transforming sequence 2 (ECT2) is frequently upregulated and acts as an oncogene in various human cancers. In addition, ECT2 was reported to be upregulated in early stage lung adenocarcinoma. However, the detailed role of ECT2 in mediating the malignant phenotypes of lung adenocarcinoma cells has not previously been elucidated. Reverse transcription-quantitative polymerase chain reaction and western blot analysis were used to examine ECT2 mRNA and protein expression levels, respectively. MTT, wound healing and Transwell assays were conducted to determine cell proliferation, migration and invasion abilities, respectively. In the present study, ECT2 was significantly upregulated in lung adenocarcinoma cell lines (H650, EKVX, HCC4006, HCC827, HCC2935, Hop62 and A549), as compared with a normal lung epithelial cell line (BEAS-2B). Moreover, knockdown of ECT2, induced by transfection with ECT2 siRNA, significantly inhibited the proliferation of lung adenocarcinoma A549 cells, whereas overexpression of ECT2 enhanced A549 cell proliferation. Furthermore, knockdown of ECT2 expression suppressed the migration and invasion of A549 cells, whereas overexpression of ECT2 enhanced the migration and invasion abilities of A549 cells. Notably, inhibition of ECT2 also suppressed the expression levels of N-cadherin and vimentin, whereas it enhanced the expression level of E-cadherin, indicating that ECT2 is associated with the epithelial-mesenchymal transition in A549 cells. On the contrary, overexpression of ECT2 enhanced the expression levels of N-cadherin and vimentin, whereas it reduced the expression level of E-cadherin in A549 cells. In conclusion, the results of the present study suggest that ECT2 has an oncogenic role in lung adenocarcinoma cells. Therefore, ECT2 may be a potential novel target for the treatment of lung adenocarcinoma. PMID- 27698698 TI - Downregulation of microRNA-132 indicates progression in hepatocellular carcinoma. AB - Although miR-132 has been studied in various human tumors, few studies have investigated the role of miR-132 in hepatocellular carcinoma (HCC). The present study aimed to evaluate the associations between miR-132 and clinicopathological parameters, including recurrence, in patients with HCC. Reverse transcription quantitative polymerase chain reaction analysis was used to detect the expression levels of miR-132 in 95 cases of HCC and their corresponding non-cancerous liver tissues. Th e associations between miR-132 expression levels and clinicopathological characteristics, including recurrence, were investigated in patients with HCC. miR-132 expression levels were significantly reduced in HCC tissues, as compared with adjacent non-cancerous tissues (1.9245+/-0.7564 vs. 2.7326+/-1.1475; P<0.001). The area under curve (AUC) of receiver operating characteristic (ROC) used to distinguish cancerous and non-cancerous tissues was 0.711 for miR-132 expression (95% confidence interval, 0.637-0.785; P<0.001) and the optimal cut-off value was 2.25. Expression levels of miR-132 were significantly reduced in the distant metastasis (P=0.031), advanced clinical TNM stage (P=0.022), hepatitis B virus-positive (P<0.001), NM23-expressed (P=0.034), high Ki-67 labeling index (LI; P=0.005) and tumor infiltration or no capsule groups (P=0.026). Spearman correlation analysis demonstrated that miR-132 was significantly correlated with hepatitis B virus infection (r=-0.351; P<0.001), NM23 (r=-0.220; P=0.032), Ki-67 LI (r=-0.264; P=0.010) and tumor capsule (r= 0.207; P=0.044). Kaplan-Meier analysis with the log-rank test indicated an approximate difference of 8 months, although miR-132 may exhibit inferior values for the prediction of recurrence in HCC patients (50.95 vs. 58.68 months; P=0.512). Therefore, the findings of the present study indicated that miR-132 is downregulated in HCC and may serve as a tumor suppressor in its progression. PMID- 27698699 TI - Decorin reduces hypertrophic scarring through inhibition of the TGF-beta1/Smad signaling pathway in a rat osteomyelitis model. AB - Chronic osteomyelitis is a bone infection that results in hypertrophic scarring of the soft tissue surrounding the infected bone. This scarring can create functional problems and its treatment is challenging. The aim of the present study was to evaluate the efficacy of decorin in treating scar formation in osteomyelitis and the underlying mechanism of its action. A rat osteomyelitis model was used, and animals were divided into three groups, as follows: Group A (control), group B (osteomyelitis model) and group C (decorin-treated). X-ray scans, hematoxylin and eosin (H&E) staining and Masson's trichrome staining were performed to observe changes in femur and muscle tissue. In order to assess the role of the transforming growth factor beta1 (TGF-beta1)/Smad signaling pathway in scar formation in osteomyelitis, alterations in muscle tissue morphology and in the activation of key members of the TGF-beta1/Smad signaling pathway were investigated in groups A and B. According to the results of H&E staining, evident fibrosis in muscle tissue were observed at days 14 and 28 in group B. Simultaneously, the expression levels of key members of the TGF-beta1/Smad signaling pathway were increased. Subsequent to treatment with decorin in group C, scarring was reduced, and significant downregulation of collagen I, TGF-beta1, phosphorylated (p)Smad2 and pSmad3 protein expression levels was observed at days 14 and 28 compared with the osteomyelitis group. In conclusion, these results suggest that activation of TGF-beta1 may serve an important role in the formation of scars in osteomyelitis and that decorin can reduce scar formation in an osteomyelitis rat model through inhibition of the TGF-beta1/Smad signaling pathway. PMID- 27698700 TI - Matrix metalloproteinase 14 participates in corneal lymphangiogenesis through the VEGF-C/VEGFR-3 signaling pathway. AB - The aim of the present study was to investigate the roles of matrix metalloproteinase 14 (MMP-14) in corneal inflammatory lymphangiogenesis. The expression of MMP-14 in vivo was detected by immunohistochemistry, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot assays, under various corneal conditions. pCMV-MMP-14 or empty pCMV vectors were injected into mouse corneal stroma, 3 days after suture placement in a standard suture-induced inflammatory corneal neovascularization assay. The outgrowth of blood and lymphatic vessels and macrophage recruitment were analyzed using immunofluorescence. The expression levels of vascular endothelial growth factor (VEGF) subtypes were tested by RT-qPCR. MMP-14 expression was upregulated significantly following various corneal injuries. The results demonstrated, for the first time, that MMP-14 strongly promotes corneal lymphangiogenesis and macrophage infiltration during inflammation. Furthermore, expression levels of VEGF-C and VEGF receptor-3, but not other VEGF components, were significantly upregulated by the intrastromal delivery of MMP-14 during corneal lymphangiogenesis. In conclusion, this study indicates that MMP-14 is critically involved in the processes of lymphangiogenesis. Inhibition of MMP-14 may provide a viable treatment for transplant rejection and other lymphatic disorders. PMID- 27698701 TI - Alien hand syndrome following corpus callosum infarction: A case report and review of the literature. AB - Alien hand syndrome (AHS) is characterized by involuntary and autonomous activity of the affected limbs, and consists of the frontal, callosal and posterior AHS variants. The callosal subtype, resulting from damage to the corpus callosum, frequently features intermanual conflict. However, infarction of the corpus callosum is rare due to abundant blood supply. The present study reported a case of AHS (callosal subtype, in the right hand) caused by callosal infarction. Infarction of the left corpus callosum was confirmed with magnetic resonance imaging. In addition, magnetic resonance angiography and digital subtraction angiography examinations revealed multiple lesions in the feeding arteries. Subsequent to antiplatelet therapy for 2 weeks following admission, the patient gradually recovered. Furthermore, the current study reviewed 31 previously reported cases of AHS following callosal infarction in the literature. PMID- 27698702 TI - Effect of early enteral nutrition on patients with digestive tract surgery: A meta-analysis of randomized controlled trials. AB - Postoperative early enteral nutrition (EEN) is useful for the effective recovery of patients that have undergone surgery. However, the feasibility and efficacy of EEN in patients with digestive tract surgery remain inconclusive. In the present meta-analysis, the PubMed, EMBASE, Web of Science, The Cochrane Library, China National Knowledge Infrastructure and VIP databases were searched to identify controlled trials of patients with and without EEN following digestive tract surgery between October, 1966 and December, 2014. Methodological quality assessment was carried out for each of the included studies. For estimation of the analysis indexes, relative risk (RR) was used as the effect size of the the categorical variable, while the weighted mean difference (MD) was used as the effect size of the continuous variable. The meta-analysis was conducted using RevMan 5.2 software. Eleven randomized controlled trials involving 1,095 patients were included in the meta-analysis. The results revealed that, EEN in patients with digestive tract surgery was more effective in decreasing the incidence of infectious [RR=0.50, 95% confidence interval (CI): 0.38, 0.67; P<0.01] and non infectious complications (RR=0.72, 95% CI: 0.43, 1.22; P<0.05) and shortening the length of first bowel action (MD=-4.10, 95% CI: -5.38, -2.82; P<0.05). It also had a significant influence on increasing the serum albumin (MD=2.87, 95% CI: 1.03, 4.71; P<0.05) and serum prealbumin (MD=0.04, 95% CI: 0.02, 0.05; P<0.05) levels. In conclusion, the results of the study have shown that EEN in patients with digestive tract surgery improved the nutritional status, reduced the risk of postoperative complications, shortened the length of hospital stay and promoted the functional recovery of the digestive system. PMID- 27698703 TI - Emergency treatment and nursing of children with severe pneumonia complicated by heart failure and respiratory failure: 10 case reports. AB - Pneumonia refers to lung inflammation caused by different pathogens or other factors, and is a common pediatric disease occurring in infants and young children. It is closely related to the anatomical and physiological characteristics of infants and young children and is more frequent during winter and spring, or sudden changes in temperature. Pneumonia is a serious disease that poses a threat to children's health and its morbidity and mortality rank first, accounting for 24.5-65.2% of pediatric inpatients. Due to juvenile age, severe illness and rapid changes, children often suffer acute heart failure, respiratory failure and even toxic encephalopathy at the same time. The concurrence in different stages of the process of emergency treatment tends to relapse, which directly places the lives of these children at risk. Severe pneumonia constitutes one of the main causes of infant mortality. In the process of nursing children with severe pneumonia, intensive care was provided, including condition assessment and diagnosis, close observation of disease, keeping the airway unblocked, rational oxygen therapy, prevention and treatment of respiratory and circulatory failure, support of vital organs, complications, and health education. The inflammatory response was proactively controlled, to prevent suffocation and reduce mortality. In summary, positive and effective nursing can promote the rehabilitation of children patients, which can be reinforced with adequate communication with the parents and/or caretakers. PMID- 27698704 TI - Anti-angiogenic effect of total saponins of Rhizoma Dioscorea nipponica on collagen induced-arthritis in rats. AB - Rheumatoid arthritis (RA) is a common chronic autoimmune and incurable disease. The aim of the present study was to investigate the therapeutic effect and mechanism of the total saponins of Rhizoma Dioscorea nipponica (TSRDN) in RA. A collagen induced-arthritis (CIA) rat model was established. CIA rats were randomly divided into three groups and lavaged with an equal volume of solvent (CIA group), TSRDN (25 mg/kg/day, RDN group) and tripterygium (TP; 12 mg/kg/day, TP group) for 21 days, respectively. Normal rats served as a control group. Hematoxylin-eosin (HE) staining was used to observe the histopathological injury of synovial tissues. The level of CD31, which used for marking and counting, micro vessel density (MVD) and the expression levels of vascular endothelial growth factor (VEGF) and signal transducer and activator of transcription 3 (STAT3) were detected by immunohistochemical analysis. Additionally, the DNA binding activity of nuclear factor-kappaB (NF-kappaB) was determined using an ELISA kit. HE staining showed obvious synovial hyperplasia, inflammatory cell infiltration, pannus formation, cartilage and bone erosion in the CIA group rats. In addition, compared with control group, the level of MVD, the expression of VEGF and STAT3, and the DNA-binding activity of NF-kappaB were all increased in CIA group rat synovial tissue (all P<0.01); however, TSRDN or tripterygium were able to inhibit these changes (all P<0.01). It was speculated that TSRDN may prevent angiogenesis by inhibiting the expression of STAT3 and the DNA-binding activity of NF-kappaB p65, thereby potentially improving CIA. PMID- 27698705 TI - Increased soluble and membrane-bound PD-L1 contributes to immune regulation and disease progression in patients with tuberculous pleural effusion. AB - Soluble and membrane-bound programmed death ligand-1 (sPD-L1 and mPD-L1, respectively) have been demonstrated to participate in the immune suppression of non-small cell lung cancer. However, the contribution of sPD-L1 and mPD-L1 to immune regulation and disease progression in patients with pleural effusions remains unknown. The present study evaluated the levels of sPD-L1 and membrane bound PD-1/PD-L1 in the peripheral blood and pleural effusions of patients with tuberculous pleural effusion (TPE), malignant pleural effusion (MPE) and non tuberculous non-malignant pleural effusion (n-TB n-M). Furthermore, selected T lymphocytes and cluster of differentiation (CD)14+ monocytes were co-cultured to investigate the potential effect of the PD-1/PD-L1 pathway in TPE. Levels of sPD L1 and PD-L1 on CD14+ monocytes were increased in the TPE group, as compared with the MPE and n-TB n-M groups. Furthermore, sPD-L1 levels and the expression levels of PD-L1 on CD14+ monocytes were demonstrated to be positively correlated with interferon (IFN)-gamma concentration in pleural effusions. Therefore, IFN-gamma may increase the expression of PD-L1 on CD14+ monocytes in vitro. Cell counting kit-8 analysis demonstrated that anti-PD-L1 antibody was able to partially reverse the proliferation of T lymphocytes in the co-culture system. The results of the present study indicated that sPD-L1 or mPD-L1 are associated with the immune regulation and disease progression of TPE, and may serve as possible biomarkers of TPE. Furthermore, sPD-L1 and the PD-1/PD-L1 pathway of TPE may be associated with the Th1 immune response; therefore, an anti-PD-1/PD-L1 pathway suggests a potential immune therapy strategy for the treatment of TPE. PMID- 27698706 TI - Sulfated polysaccharide-protein complex sensitizes doxorubicin-induced apoptosis of breast cancer cells in vitro and in vivo. AB - The present study aimed to investigate the effect of sulfated polysaccharide protein complex (SPPC) on the antitumor effect of doxorubicin (Dox) on MDA-MB-231 breast cancer cells in vitro and in vivo. MTT and Annexin V/propidium iodide staining assays demonstrated that SPPC selectively sensitized MDA-MB-231 cells to Dox-induced cytotoxicity. The half maximal inhibitory concentration of Dox against MDA-MB-231 cells was decreased from 5.3 to 1.5 uM when it was used concomitantly with 5 uM SPPC. SPPC potentiated Dox-induced apoptosis in breast cancer cells via the mitochondrial apoptosis signaling pathway by activating caspase-3 and caspase-9. Notably, the caspase inhibitor Z-VAD-fmk diminished the effect of SPPC on Dox-mediated apoptosis. Furthermore, combination treatment with SPPC and Dox markedly reduced the growth of breast cancer xenografts in mice. The present study demonstrated that SPPC was able to enhance the antitumor effect of Dox on breast cancer cells, thus suggesting that SPCC may be used to reduce the cumulative dose of Dox and its associated toxicities in the chemotherapy of breast cancer and other types of cancer. PMID- 27698707 TI - Acetylsalicylic acid combined with diclofenac inhibits cartilage degradation in rabbit models of osteoarthritis. AB - The present study aimed to investigate the effect of different concentrations of acetylsalicylic acid combined with diclofenac on the articular cartilage of a rabbit model of osteoarthritis (OA). A total of 40 New Zealand white rabbits were divided into 5 groups. Group A was a sham-operated control group, which was treated with normal saline. Groups B-E were OA models and were treated with normal saline and acetylsalicylic acid combined with diclofenac at concentrations of 5, 10 and 20 mg/kg, respectively. A cartilage macroscopic examination and a pathological observation were performed to analyze the structure of the articular cartilage in all of the treated groups. The nitric oxide (NO) content and interleukin 1beta (IL-1beta) levels were detected by an enzyme-linked immunosorbent assay. In addition, the protein expression of matrix metalloproteinase 3 (MMP)-3 and MMP-13 were detected by western blot analysis. The mRNA expression of tissue inhibitor of metalloproteinases 1 (TIMP1) was detected by polymerase chain reaction (PCR). The results revealed that different concentrations of the drugs significantly reduced the scores of cartilago articularis, the NO and IL-1beta levels and the protein expression of MMP-3 and MMP-13. Furthermore, PCR revealed that the mRNA expression of TIMP1 was significantly upregulated, and the effects increased with increasing drug concentration. Thus, the administration of different concentrations of acetylsalicylic acid combined with diclofenac demonstrates preventive or therapeutic effects against OA progression. PMID- 27698708 TI - Branch retinal artery occlusion following carotid stenting: A case report. AB - A 70 year old male was diagnosed with carotid stenosis and underwent carotid artery stenting (CAS). Severe postoperative complications arose subsequent to the procedure, including decreased visual acuity and symptoms of a visual field defect, and the patient was eventually diagnosed with retinal artery embolism. CAS reduces carotid plaque; however, the subsequent shedding of carotid plaque may cause retinal artery embolism, resulting in the serious loss of visual function in patients. This complication is of paramount importance and requires great consideration from the neurologist and the patients undergoing CAS. Ophthalmic evaluation is paramount following CAS due to the possibility of embolic occlusion of the retinal artery. It is imperative that patients be informed of the risk of permanent vision loss as a result of CAS. PMID- 27698709 TI - Rotavirus-associated immune thrombocytopenic purpura in children: A retrospective study. AB - Certain studies have previously indicated that an association may exist between rotavirus infection and primary immune thrombocytopenic purpura (ITP). The present retrospective study aimed to investigate whether rotavirus may cause ITP in children. Firstly, the incidence of ITP in children with or without rotavirus diarrhea was compared. A 14.58% incident rate was observed in children with rotavirus diarrhea compared with a 7.22% incident rate in children without rotavirus diarrhea. Subsequently, the clinical features of ITP children with or without rotavirus infection were compared. The results indicated that ITP children with rotavirus infection were significantly younger, showed significantly decreased mean platelet volume (MPV) levels and presented a significantly higher frequency of bleeding score of 3 against ITP children without rotavirus infection. In conclusion, these findings suggest that rotavirus serves a causative role in ITP. PMID- 27698710 TI - Decorin inhibits the proliferation of HepG2 cells by elevating the expression of transforming growth factor-beta receptor II. AB - The aim of the present study was to investigate the effects of decorin (DCN) on the proliferation of human hepatoma HepG2 cells and the involvement of transforming growth factor-beta (TGF-beta) signaling pathway. A vector containing DCN was transfected into HepG2 cells with the use of Lipofectamine 2000. Cell proliferation was assessed with an MTT assay, and western blot analysis was used to detect the protein expression of TGF-beta receptor I (TGF-betaRI), phosphorylated TGF-betaRI, p15 and TGF-betaRII. In addition, small interfering RNA (siRNA) silencing was performed to knock down the target gene. The results indicated that, compared with the control group, cell proliferation was significantly decreased in HepG2 cells transfected with DCN. In addition, DCN transfection significantly increased the phosphorylation level of TGF-betaRI in HepG2 cells. The expression of the downstream factor p15 was also significantly elevated in the DCN-transfected HepG2 cells. Furthermore, DCN transfection significantly elevated the expression level of TGF-betaRII in HepG2 cells. By contrast, the silencing of TGF-betaRII significantly decreased the phosphorylation of TGF-betaRI in DCN-transfected HepG2 cells. In addition, TGF betaRII silencing abolished the effects of DCN on the proliferation of HepG2 cells. In conclusion, DCN elevated the expression level of TGF-betaRII, increased the phosphorylation level of TGF-betaRI, enhanced the expression of p15, and finally inhibited the proliferation of HepG2 cells. These findings may contribute to the understanding of the role of DCN in the pathogenesis of hepatic carcinoma and assist in the disease treatment. PMID- 27698711 TI - Biological significance of PinX1 telomerase inhibitor in esophageal carcinoma treatment. AB - In the present study, to investigate the expression of PinX1 gene and its functional effects in human esophageal carcinoma (Eca)-109 cell line, expression vectors of human PinX1 (pEGFP-C3-PinX1) and its small interfering RNA (PinX1-FAM siRNA) were constructed and transfected into Eca-109 cells using Lipofectamine 2000. Firstly, the mRNA expression level of PinX1 was examined using reverse transcription-polymerase chain reaction (RT-PCR). Once successful transfection was achieved, the effects on the mRNA level of human telomerase reverse transcriptase (hTERT), telomerase activity, cell proliferation and apoptosis were examined by semi-quantitative RT-PCR, stretch PCR, MTT assay and flow cytometry, respectively. Analysis of restriction and sequencing demonstrated that the recombining plasmids were successfully constructed. The results also indicated that transfection with pEGFP-C3-PinX1 and PinX1-FAM-siRNA into Eca-109 cells significantly increased PinX1 mRNA, decreased hTERT mRNA by 29.9% (P<0.05), and significantly reduced telomerase activity (P<0.05), inhibited cell growth, and increased the cell apoptotic index from 19.27+/-0.76 to 49.73+/-2%. The transfected PinX1-FAM-SiRNA exhibited PinX1 mRNA expression levels that were significantly decreased by 70% (P<0.05), whereas the remaining characteristics of Eca-109 cells, including cell growth, mRNA level of hTERT, telomerase activity and cell apoptotic index were not altered. Exogenous PinX1 has been demonstrated to be highly expressed in human Eca. PinX1 can inhibit human telomerase activity and the expression of hTERT mRNA, reduce tumor cell growth and induce apoptosis. Notably, these inhibitory functions were inhibited by silencing PinX1 in Eca with PinX1-FAM-siRNA. PinX1 was successfully increased and decreased in the present study, demonstrating that it may be a potential telomerase activity inhibitor. As PinX1 is an endogenous telomerase inhibitor, it may be used as a novel tumor targeted gene therapy. PMID- 27698713 TI - C1 inhibitor-mediated myocardial protection from chronic intermittent hypoxia induced injury. AB - The optimal treatment for chronic intermittent hypoxia (CIH)-induced cardiovascular injuries has yet to be determined. The aim of the current study was to explore the potential protective effect and mechanism of a C1 inhibitor in CIH in the myocardium. The present study used a rat model of CIH in which complement regulatory protein, known as C1 inhibitor (C1INH), was administered to the rats in the intervention groups. Cardiomyocyte apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling. The expression of proteins associated with the apoptotic pathway, such as B-cell lymphoma 2 (Bcl-2), Bax and caspase-3 were detected by western blot analysis. The expression of complement C3 protein and RNA were also analyzed. C1INH was observed to improve the cardiac function in rats with CIH. Myocardial myeloperoxidase activity, a marker of neutrophil infiltration, was significantly decreased in the C1INH intervention group compared with the CIH control group, and cardiomyocyte apoptosis was significantly attenuated (P<0.05). Western blotting and reverse transcription-polymerase chain reaction analysis indicated that the protein expression levels of Bcl-2 were decreased and those of Bax were increased in the CIH group compared with the normal control group, but the protein expression levels of Bcl-2 were increased and those of Bax were decreased in the C1INH intervention group, as compared with the CIH group. Furthermore, the CIH-induced expression and synthesis of complement C3 in the myocardium were also reduced in the C1INH intervention group. C1INH, in addition to inhibiting complement activation and inflammation, preserved cardiac function in CIH mediated myocardial cell injury through an anti-apoptotic mechanism. PMID- 27698712 TI - Gelatin sponge microparticles for the treatment of the spontaneous rupture of hepatocellular carcinoma hemorrhage. AB - Spontaneous rupture of hepatocellular carcinoma hemorrhage is life-threatening. The aim of the present study was to retrospectively analyze the effect of gelatin sponge microparticles (GSMs) of various diameters on the treatment of spontaneous rupture of hepatocellular carcinoma hemorrhage. GSMs serve as embolization agents by transcatheter arterial chemoembolization (TACE), and the current study analyzed their safety and efficacy. Data from a total of 13 cases of spontaneous rupture of hepatocellular carcinoma hemorrhage, who were treated with GSM-TACE at the Affiliated Zhongshan Hospital of Dalian University (Dalian, China) between August 2010 and June 2014, were collected. Post-operative complications were classified according to the National Cancer Institute Common Terminology Criteria. Review computed tomography was conducted 1, 3 and 6 months after GSM TACE treatment in order to determine the occurrence of re-bleeding; the tumor response was evaluated based on the Modified Response Evaluation Criteria In Solid Tumors and the expression levels of alpha-feroprotein. The patients were followed-up for 1-6 months (average, 5.15+/-1.67 months). Following GSM-TACE treatment, 13 cases reached successful hemostasis without technical complications. The survival rates 1, 3 and 6 months after treatment were 76.9 (10/13), 61.5 (8/13) and 53.8% (7/13), respectively; the objective response rates were 61.6, 53.9 and 38.5%, respectively. The primary post-operative complications were pain (100%), nausea and vomiting (69.2%), and fever (53.8%). Among the 13 patients, 2 cases underwent surgical excision 10 and 30 days after GSM-TACE, and 1 case experienced re-bleeding 3 months after treatment, after which the patient received a second treatment with TACE and successful achieved hemostasis. In conclusion, GSM-TACE of various diameters is a safe and effective method in the treatment of spontaneous rupture of hepatocellular carcinoma hemorrhage. GSM-TACE is able to achieve immediate hemostasis and improves the survival rate of patients, thus creating favorable conditions for follow-up treatment. PMID- 27698714 TI - Diagnostic values of red cell distribution width, platelet distribution width and neutrophil-lymphocyte count ratio for sepsis. AB - The aim of this study was to evaluate the diagnostic efficiency of red blood cell distribution width (RDW), platelet distribution width (PDW), the neutrophil lymphocyte count ratio (NLCR), procalcitonin (PCT) and C-reactive protein (CRP) for the prediction of sepsis. A total of 120 consecutive patients who underwent blood culture testing were included. The PCT and CRP levels, and RDW, PDW and NLCR percentages were determined and compared between patients with positive blood cultures and those without. The PCT, CRP, RDW, PDW and NLCR values were significantly higher in patients with positive blood culture compared with those without. PCT and NLCR each had a high diagnostic performance for the prediction of sepsis, with an area under the curve (AUC) for sepsis of 0.829 and 0.718, respectively. A combination of RDW, PDW and NLCR also exhibited a good diagnostic performance for sepsis (AUC, 0.704). NLCR is easily obtained by automated hematological analysis. Moreover, NLCR was found to have a high diagnostic efficiency for the prediction of sepsis, with greater sensitivity and accuracy than CRP. In conclusion, PCT exhibited the optimal diagnostic performance among the tested markers. The combination of the three parameters of RDW, PDW and NLCR, demonstrated a high diagnostic performance similar to that of PCT. PMID- 27698715 TI - Microarray analysis reveals altered circulating microRNA expression in mice infected with Coxsackievirus B3. AB - Coxsackievirus B3 (CVB3) is a common causative agent in the development of inflammatory cardiomyopathy. However, whether the expression of peripheral blood microRNAs (miRNAs) is altered in this process is unknown. The present study investigated changes to miRNA expression in the peripheral blood of CVB3-infected mice. Utilizing miRNA microarray technology, differential miRNA expression was examined between normal and CVB3-infected mice. The present results suggest that specific miRNAs were differentially expressed in the peripheral blood of mice infected with CVB3, varying with infection duration. Using miRNA microarray analysis, a total of 96 and 89 differentially expressed miRNAs were identified in the peripheral blood of mice infected with CVB3 for 3 and 6 days, respectively. Quantitative polymerase chain reaction was used to validate differentially expressed miRNAs, revealing a consistency of these results with the miRNA microarray analysis results. The biological functions of the differentially expressed miRNAs were then predicted by bioinformatics analysis. The potential biological roles of differentially expressed miRNAs included hypertrophic cardiomyopathy, dilated cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy. These results may provide important insights into the mechanisms responsible for the progression of CVB3 infection. PMID- 27698716 TI - Fulminant bilateral acute retinal necrosis syndrome associated with viral encephalitis: A case report. AB - Herpes simplex virus (HSV) is the most common cause of acute viral encephalitis. Acute retinal necrosis (ARN) is a rapidly progressing and potentially blinding eye disease that may be induced by HSV. The present case study reports the very rare case of a patient with herpes simplex encephalitis (HSE) combined with acute retinal necrosis (ARN). A 47-year-old woman was admitted to hospital with persistent high fever and somnolence for 5 days. Magnetic resonance imaging showed abnormal signals in the right medial temporal lobes, and HSV-1 was identified in the serum and cerebrospinal fluid. Five days later, despite treatment with intravenous acyclovir and partial improvement in consciousness, the patient suddenly developed blurred vision and bilateral visual pain. Fundus fluorescence angiography revealed bilateral vessel obstruction and flaky reduced fluorescence. ARN was diagnosed clinically. Dexamethasone was administered as an anti-inflammatory adjunct to intravenous acyclovir therapy. The visual acuity of the patient was reduced to mere light perception a further 4 days later. The present case indicates that HSE may be complicated with ARN, causing a reduction in visual acuity to mere light perception within a very short time. PMID- 27698718 TI - Mediastinal syndrome: A report of three cases. AB - Mediastinal syndromes are a group of disorders involving the anatomical structures of the mediastinum. An increase in the incidence of this syndrome has been observed following the widespread use of diagnostic imaging. In the present study, three different cases of mediastinal syndrome, one of which was complicated by superior vena cava syndrome, are discussed. The treatment in the three cases was dependent on the etiology. While a patient with goiter experienced resolution of the symptoms following thyroidectomy, and a patient with lymphoma experienced beneficial effects following medical treatment, the patient with lymph node metastasis caused by a gastric tumor succumbed to the disease. In conclusion, the present case reports demonstrated that mediastinal syndrome is a life threatening condition whose prognosis depends on the underlying cause. PMID- 27698717 TI - Tissue injuries after single-port and multiport laparoscopic gynecologic surgeries: A prospective multicenter study. AB - The present study focused on the degree of tissue injury following single-port laparoscopic surgery (SPLS) and multiport laparoscopic surgery (MPLS) for the treatment of various benign gynecologic diseases. A total of 228 patients were prospectively enrolled at seven academic centers in South Korea between April 2011 and September 2012. Of these, 122 patients underwent SPLS and 106 patients underwent MPLS. The serum levels of C-reactive protein, creatine phosphokinase, lactic dehydrogenase and cancer antigen 125 were measured preoperatively and on postoperative day 4 by immunonephelometry. Cosmetic satisfaction and postoperative pain scores (visual analogue scale) were analyzed. Postoperative changes in the levels of the serum markers were found to be similar between the SPLS and MPLS groups. However, the postoperative pain scores at 48 h were significantly lower in the SPLS group when compared with those in the MPLS (P=0.001). In addition, patient-controlled analgesia was used more frequently by patients in the MPLS group (P=0.003). The present study is the first prospective investigation of tissue injury resulting from SPLS and MPLS in gynecology. In conclusion, the current study demonstrated that serum marker levels during SPLS were similar to those during MPLS in the treatment of benign gynecologic diseases. However, SPLS is a reasonable alternative to MPLS and is associated with comparable tissue injury, improved cosmesis and reduced postoperative pain. PMID- 27698719 TI - Endothelium-dependent and-independent relaxation induced by resveratrol in rat superior mesenteric arteries. AB - Resveratrol (Res) is a specific agonist of sirtuin 1, and has many cardioprotective effects. Although Res is able to relax various vascular beds, its pharmacological properties in rat superior mesenteric arteries and the underlying mechanism are not well clarified. The aim of present study was to investigate the vasorelaxant effects of Res on rat superior mesenteric arteries and the mechanisms involved. The isometric tension of rat superior mesenteric arterial rings was recorded in vitro using myography. It was found that Res concentration-dependently relaxed endothelium-intact superior mesenteric artery rings pre-contracted by phenylephrine hydrochloride (Emax, 97.66+/-0.79%; pD2, 4.30+/-0.14) or KCl (Emax, 101.3+/-0.6%; pD2, 4.12+/-0.03). The vasorelaxant effect of Res on the superior mesenteric artery rings was partially endothelium dependent. NG-nitro-L-arginine methyl ester (100 uM) significantly inhibited the Res-induced vasorelaxant effect. However, 1H-[1,2,4]oxadiazolo[4,3-a] quinoxalin 1-one (10 uM) and indomethacin (5 uM) each had no effect on the Res-induced vasorelaxation. In artery rings without endothelium, the vasorelaxation induced by Res was attenuated by 4-aminopyridine (100 uM) and glibenclamide (10 uM). However, barium chloride dehydrate (10 uM) and tetraethylammonium chloride (1 mM) did not affect the vasorelaxation induced by Res. Moreover, Res also inhibited the contraction induced by an increase in external calcium concentration in Ca2+ free medium plus KCl (60 mM). These results suggest that Res induces relaxation in superior mesenteric arterial rings through an endothelium-dependent pathway, involving nitric oxide release, and also through an endothelium-independent pathway, with opening of voltage-dependent K+ channels and ATP-sensitive K+ channels and blockade of extracellular Ca2+ influx. PMID- 27698720 TI - Homocysteine injures vascular endothelial cells by inhibiting mitochondrial activity. AB - The aim of the present study was to investigate the role of homocysteine (Hcy) in the pathogenesis of pulmonary embolism (PE) and the associated molecular mechanisms in human umbilical vein endothelial cells (HUVECs). Hcy contents were detected with high-performance liquid chromatography. Apoptosis was detected by flow cytometry using Annexin-V staining. Cytochrome c oxidase (COX) activity was assessed with an enzyme activity assay, and the expression levels of COX 17 were determined by western blot analysis. Intracellular reactive oxygen species levels were measured using a microplate reader with a fluorescence probe. The results demonstrated that, compared with the control group, the serum Hcy levels were significantly elevated in the PE group, suggesting that Hcy may be an indicator for PE. Following treatment with Hcy, the apoptosis rate was markedly elevated in HUVECs. Moreover, Hcy decreased COX activity and downregulated the expression of COX 17 in HUVECs. Furthermore, Hcy increased the ROS levels in these endothelial cells. However, all the above-mentioned physiopathological changes induced by Hcy in HUVECs could be restored by folic acid. In conclusion, the results of the present study demonstrated that Hcy inhibited COX activity, downregulated COX 17 expression, increased intracellular ROS levels and enhanced apoptosis in endothelial cells. PMID- 27698721 TI - siRNA-mediated silencing of phosphodiesterase 4B expression affects the production of cytokines in endotoxin-stimulated primary cultured microglia. AB - Phosphodiesterase 4 (PDE4) has four subtypes: PDE4A, PDE4B, PDE4C and PDE4D. The expression of PDE4 subtypes in microglial cells and the specific contribution of each subtype to inflammation remain unclear. In this study, the expression of PDE4 subtypes in primary microglial cells was assayed. Primary microglial cells were then transfected with specific small interfering RNA (siRNA) against each PDE4 subtype. PDE4 subtype A-D knockdown was confirmed by quantitative polymerase chain reaction. Secreted cytokines in the supernatant and intracellular cyclic adenosine monophosphate (cAMP) levels of transfected cells were measured. The effect of PDE4B siRNA on the activation of extracellular regulated protein kinase (ERK) induced by lipopolysaccharide (LPS) in microglia was further tested by western blotting. Results showed that the primary microglial cells expressed all four types of PDE4s at the protein level. Transfection with the four siRNAs inhibited PDE4 subtype A-D mRNA expression, respectively. In primary microglial cells, treatment with PDE4B siRNA significantly inhibited the expression of tumor necrosis factor-alpha and interleukin (IL)-1beta, and enhanced the expression of cAMP, while siRNAs to other subtypes had no significant effects. However, none of the four siRNAs had any significant effect on the expression of IL-10. Furthermore, in the PDE4B group, the level of phosphorylated ERK was reduced. Among the four PDE4 subtypes, PDE4B plays an important role in regulating inflammatory responses in microglia, potentially through initially regulating the intracellular cAMP concentration. PMID- 27698722 TI - Analysis of the first therapeutic-target-achieving time of warfarin therapy and associated factors in patients with pulmonary embolism. AB - The present study aimed to investigate the factors affecting the first therapeutic-target-achieving (TTA) time of warfarin therapy in patients with acute pulmonary embolism (PTE). Between January 2008 and June 2013, patients with PTE confirmed by transpulmonary arterial enhanced computed tomographic pulmonary angiography or pulmonary ventilation perfusion scanning were included in the present study. Data collected included demographic information, history of tobacco and alcohol intake, basic diseases (stable and unstable hypertension, diabetes, heart failure, cancer/cerebral infarction, old myocardial infarction and atrial fibrillation), liver and kidney function, the haemoglobin and platelet count of the blood, international normalized ratio monitoring, warfarin dosage adjustment and medication combinations. Dynamic changes in international normalized ratio, anticoagulant efficacy, and adverse events within 90 days were monitored and analyzed. Univariate analysis demonstrated that the following factors affect the first TTA time: Initial dose, body mass index (BMI), liver function, heart failure, and the administration of levofloxacin, cephalosporins, and blood circulation-activating drugs. Logistic regression analysis revealed that the following were independent factors of the first TTA time: Initial dose, BMI, liver function, heart failure and levofloxacin. Therefore, the results of the present study demonstrated that various factors may affect the first TTA time of warfarin therapy, including the initial dose, BMI, liver function, heart function and concomitant medication. PMID- 27698723 TI - Role of nucleolar protein NOM1 in pancreatic islet beta cell apoptosis in diabetes. AB - Diabetes is a metabolic disease that results from impairment in insulin secretion. The present study aimed to investigate the potential role of NOM1 in the function of pancreatic islet beta cells and insulin secretion. MIN6 cells isolated from mice were transfected with siRNA-NOM1 to assess the influence of NOM1 on the expression of the cell apoptosis-associated proteins, such as caspase 3. In addition, MIN6 cells were cultured in medium containing different glucose concentrations in order to assess the sensitivity of MIN6 cells to glucose. The effect of NOM1 expression and glucose on MIN6 cell proliferation was also analyzed using an MTT assay. Furthermore, the mRNA expression levels of insulin 1 and 2 in MIN6 cells were detected using reverse transcription-quantitative polymerase chain reaction, while the expression levels of various cell apoptosis associated proteins, Bcl-2 and Bax, were analyzed using western blot analysis. Compared with the control group, downregulation NOM1 and high glucose concentration of 25 mM significantly increased the cleaved caspase-3 level in MIN6 cells (P<0.05). In addition, downregulation of NOM1 significantly inhibited the MIN6 cell proliferation ability and reduced the insulin 2 mRNA expression (P<0.05). NOM1 knockdown also resulted in significantly increased Bax2 level and decreased Bcl-2 level in MIN6 cells (P<0.05). However no significant difference in insulin mRNA expression was observed between the control and siRNA-NOM1 transfected group (P>0.05). In conclusion, the present study suggested that NOM1 expression may be affected by blood glucose, and that NOM1 may be associated with pancreatic islet beta cell apoptosis. In addition, NOM1 may serve a pivotal role in diabetes by affecting insulin synthesis and secretion in pancreatic islet beta cells. PMID- 27698724 TI - Clinical characteristics and analysis of familial oral lichen planus in eight Chinese families. AB - Oral lichen planus (OLP) is one of the most common oral mucosa diseases; however, familial OLP is uncommon. The present study reported and analyzed patients with familial OLP (n=18) in eight different Chinese families between January 1, 2012 and December 31, 2013. Parameters analyzed include gender, age at diagnosis, lesion distribution and lesion type. The follow-up period for each patient was a minimum of 1 year. In this survey, 18/88 individuals in the eight families were affected. Females were more frequently affected, and the female to male ratio for familial OLP (2.2:1) was higher compared with that previously reported for nonfamilial OLP (1.4:1). The age at diagnosis, lesion distribution and lesion type showed consistency with reports concerning nonfamilial OLP, with the exception of family VI, in which 4/5 children had OLP/LP lesions and were of an early age at diagnosis. There were two families in which three generations had been affected by OLP. In addition, it appeared that patients of the same generation in the same family were of a similar age at diagnosis. No malignant or premalignant lesion was identified in the 18 individuals diagnosed with OLP from the eight families. The present study supports the hypothesis that genetic predisposition may serve a role in the etiology of OLP. PMID- 27698725 TI - Assessment of myocardial viability with delayed-enhancement MRI in coronary artery disease: A correlative study with coronary artery stenosis using digital subtraction angiography. AB - The aim of the present study was to investigate the correlation between the degree of coronary artery stenosis determined by digital subtraction angiography (DSA) and infarcted segments detected by delayed enhancement magnetic resonance imaging (DE-MRI). DE-MRI and DSA were performed in 40 patients with coronary artery disease. The number of myocardial segments with infarction, the transmural extent of myocardial infarction, score of myocardial infarction by MRI, degree of coronary artery stenosis and Gensini score of the coronary artery were assessed. The correlation was analyzed using Spearman's rank correlation test. Among the 40 patients, 126 infarcted myocardial segments with a total score of 307 were found by DE-MRI; the total Gensini score for coronary artery stenosis was 587. It was observed that 81.74% of the infarcted segments were at sites with >50% coronary artery stenosis. The correlation coefficient between the Gensini score and myocardial infarction score was 0.786 (P<0.001), indicating a good correlation. However, 18.26% of myocardial infarction segments were found in patients with slight coronary artery stenosis (<=25%). A correlation was identified between DSA detected coronary artery stenosis and infarcted segments detected by DE-MRI; a higher transmural extent of myocardial infarction correlated with more severe stenosis of the coronary artery. The combined use of the two tools may facilitate accurate diagnosis. PMID- 27698726 TI - Evaluation of the effects of ketamine on spinal anesthesia with levobupivacaine or ropivacaine. AB - Spinal anesthesia or regional anesthesia is a potent anesthetic procedure. Additional modalities have been sought to increase the duration of block in spinal anesthesia. Ketamine is an N-methyl-D-aspartate (NMDA) receptor blocker that has an anesthetic effect when injected intrathecally and has a synergic effect with bupivacaine. Ketamine also has potent analgesic properties. The present study investigated the effect of intrathecally administered ketamine on spinal anesthesia with levobupivacaine or ropivacaine. Sprague-Dawley rats at post-natal day 21 were exposed to spinal anesthesia with 0.5% levobupivacaine or 0.5% ropivacaine. Separate groups of rats were treated with intrathecal ketamine at a 5 or 10 mg/kg bodyweight dose along with ropivacaine or levobupivacaine. The thermal and mechanical withdrawal latencies of the animals were determined using hot plate and von Frey filaments, respectively. A rotarod apparatus was employed to assess the capacity of the rats to rotate the spindle at 24 h following anesthesia. The gait of the rat pups was also assessed. Intrathecal administration of ketamine resulted in dense blocks and extended the duration of spinal blocks as evidenced by thermal latencies and responses to von Frey filaments. The latency to fall was shorter in rats exposed to ketamine along with ropivacaine or levobupivacaine spinal anesthesia. The gait parameters were also more disturbed upon ketamine administration. In conclusion, ketamine administration with ropivacaine or levobupivacaine increased the intensity and duration of spinal blockade, thereby increasing the anesthetic effects. PMID- 27698727 TI - Partial response to imatinib treatment in a patient with unresectable gastrointestinal stromal tumor: A case report and mini literature review. AB - The aim of the present study was to evaluate the efficacy and safety of imatinib mesylate in unresectable gastrointestinal stromal tumor (GIST) and to discuss its therapeutic regimen. A patient with unresectable GIST is described, and several key clinical studies are reviewed, including the clinical trials B2222 and S0033, which contain recently reported results of the long-term clinical outcome of imatinib in patients with unresectable or metastatic GIST. The recent results of the two studies demonstrate the long-term efficacy and safety of imatinib for unresectable or metastatic GIST. A positive response to imatinib treatment was observed in the present patient, which is consistent with the data of the B2222 and S0033 trials. However, further long-term, large-scale, multicenter and controlled trials are required to determine the relative efficacy of combining imatinib agents with surgical procedures or administering imatinib alone. PMID- 27698728 TI - Influencing factors of transient elastography in detecting liver stiffness. AB - Liver stiffness, which correlates well with liver fibrosis stage, can be measured noninvasively by transient elastography, also known as Fibroscan. The present study aimed to determine the independent factors influencing Fibroscan detection by multiple regression analysis. A total of 181 patients who required liver biopsy were enrolled. Liver stiffness measurement (LSM) was detected by Fibroscan on the day of liver biopsy, while clinical information and routine biochemical examination results were also collected. Correlation was analyzed by Spearman's correlation, and multiple regression analysis was performed to analyze the independent influencing factors. The results demonstrated that platelet (PLT) levels, serum albumin (ALB), prothrombin activity (PTA) and body mass index (BMI) were independent predictors of liver stiffness. The contribution of these four predictors to the regression equation was in the following descending order: PLT (negative correlation) > ALB (negative correlation) > PTA (negative correlation) > BMI (positive correlation). In conclusion, the parameters of PLT, ALB, PTA and BMI are independent predicting factors affecting Fibroscan detection. Therefore, the diagnosis and evaluation of liver fibrosis should comprehensively consider the results of Fibroscan, and clinical and laboratory examinations. PMID- 27698729 TI - Triptolide inhibits the progression of atherosclerosis in apolipoprotein E-/- mice. AB - Atherosclerosis, the major cause of cardiovascular disease, is accompanied by a chronic inflammatory response during the disease. Triptolide (TPL) is an active natural compound that has been demonstrated to possess anti-inflammatory activities in various cell types. However, the effects of TPL on atherosclerosis have not yet been studied. The goal of the present study was to determine the effects of TPL on apolipoprotein E knock-out (ApoE-/-) mice fed with a high-fat diet and to analyze the changes in lipid metabolism and inflammatory cytokines to clarify the underlying molecular mechanisms. Firstly, the genotypes of ApoE-/- mice and corresponding wild-type mice were identified using polymerase chain reaction. The ApoE-/- mice were randomly divided into four groups: ApoE-/- model mice, and ApoE-/- mice treated with 25, 50 or 100 ug/kg TPL every twice day. Wild type mice with the same genetic background constituted the fifth group. The mice in each group were given a high-fat diet from week 8 after birth until week 20. Total cholesterol and total triglyceride levels were determined at 16 and 20 weeks. The results demonstrated that the levels of total cholesterol and total triglyceride in the plasma were highly increased in ApoE-/- mice models, compared with those of wild-type mice, and the ApoE-/- mice treated with TPL had decreased levels of total cholesterol and total triglyceride in plasma, which exhibited a dose-dependent reduction as the dose of TPL increased. Moreover, the effects of TPL on the production of inflammatory cytokines in macrophages were determined by ELISA. The results demonstrated that the macrophages from ApoE-/- mice produced high levels of the inflammatory cytokines tumor necrosis factor-alpha, interleukin (IL)-1beta, IL-6 and IL-8. However, following treatment with TPL doses of 25, 50 and 100 ug/kg, the cytokine levels were significantly decreased in a dose-dependent manner. Additionally, proteins associated with lipid metabolism were tested by western blotting. The results showed that the expression of anti-ATP-binding cassette transporter A1 in the macrophages of ApoE /- mice was increased following treatment with TPL. However, the expression levels of LXRalpha were not markedly changed following treatment of the mice with different doses of TPL. These results suggest that TPL inhibited the progression of atherosclerosis not only by inhibiting the chronic inflammatory response, but also by regulating lipid metabolism, which may provide new insights useful in the clinical therapy of atherosclerosis. PMID- 27698730 TI - Surgical treatment of incarcerated calculi via laparoscopic bile duct exploration using laparotomy biliary lithotomy forceps. AB - The present study aimed to investigate the practicability and clinical value of applying laparotomy biliary lithotomy forceps to laparoscopic bile duct exploration (LCBDE) for the surgical treatment of incarcerated calculi. A total of 63 patients were diagnosed with cholecystolithiasis and choledocholithiasis. The present study performed a retrospective analysis of clinical samples from 16 of these patients who had incarcerated calculi at the terminus of the common bile duct, and who had been treated with laparoscopic cholecystectomy and LCBDE. During the procedure, laparotomy biliary lithotomy forceps were used to gently remove the calculi from the common bile duct. Of the surgical procedures that used laparotomy biliary lithotomy forceps, one case was unsuccessful and 15 cases were successful. The results of the present study suggested that it may be clinically advisable to use laparotomy biliary lithotomy forceps to remove incarcerated calculi from the common bile duct during a laparoscopy, since it is easy, economical and effective. PMID- 27698731 TI - Quality evaluation of Heshouwu, a Taoist medicine in Wudang, China. AB - Polygonum multiflorum Thunb., which is known as Heshouwu in China, is a Taoist medicine sourced from the Wudang mountain area. At present, the quality of the Heshouwu sourced from this region is unknown. The present study aimed to evaluate the quality of wild Heshouwu collected from the Wudang mountain area, particularly the 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside (TSG) and combined anthraquinone (CAQ) content, compared with that of commercially available Heshouwu. Furthermore, the potential quantities of organic pesticide residues were determined. High performance liquid chromatography with a diode array detector was used to quantify TSG and CAQ content, whereas gas chromatography (GC), performed using a temperature gradient, was used to detect the presence of organochlorine, pyrethroid and organophosphorus pesticides. The average TSG content present in the wild Heshouwu from the Wudang mountain area and in the commercially available Heshouwu was 2.39 and 1.10%, respectively. In addition, the average content of CAQ in these was 1.41 and 3.46%, respectively. GC did not detect residues of organic pesticides in the wild Heshouwu, thus this plant met the criterion of the Chinese Pharmacopeia (2010 edition). The results of the present study indicated that wild Heshouwu from the Wudang mountain area may be suitable for use as a Chinese medicine across China. PMID- 27698732 TI - Recombinant expression and biological characterization of the antimicrobial peptide fowlicidin-2 in Pichia pastoris. AB - Fowlicidins are a group of cathelicidin antimicrobial peptides that were initially identified in chickens. Fowlicidin-2, which is composed of 31 amino acids, is widely expressed in the majority of tissues in chickens and has an important role in innate immunity. In the present study, a recombinant expression system for fowlicidin-2 was successfully constructed using Pichia pastoris X-33 and the expression vector pPICZalpha-A. Under the optimized fermentation conditions, 85.6 mg fowlicidin-2 with >95% purity was obtained from 1 liter culture medium following purification by ion exchange chromatography and reversed phase high performance liquid chromatography. The recombinant fowlicidin-2 exhibited broad spectrum antimicrobial activity and had a minimum inhibitory concentration ranging from 1 to 4 uM. Furthermore, recombinant fowlicidin-2 exhibited hemolytic activity, promoting 50% human erythrocyte hemolysis in the concentration range of 128-256 uM, and anticancer activity, resulting in the death of 50% of A375 human malignant melanoma cells in the concentration range of 2-4 uM. The results of the present study suggest that recombinant fowlicidin-2 may be a promising candidate for therapeutic applications. PMID- 27698733 TI - Role of PiCCO monitoring for the integrated management of neurogenic pulmonary edema following traumatic brain injury: A case report and literature review. AB - Neurogenic pulmonary edema (NPE) is occasionally observed in patients with traumatic brain injury (TBI); however, this condition is often underappreciated. NPE is frequently misdiagnosed due to its atypical clinical performance, thus delaying appropriate treatment. A comprehensive management protocol of NPE in patients with TBI has yet to be established. The current study reported the case of a 67-year-old man with severe TBI who was transferred to our intensive care unit (ICU). On day 7 after hospitalization, the patient suddenly suffered tachypnea, tachycardia, systemic hypertension and hypoxemia during lumbar cistern drainage. Intravenous diuretics, tranquilizer and glucocorticoid were administered due to suspected left heart failure attack. Chest radiography examination supported the diagnosis of pulmonary edema; however, hypotension and hypovolemia were subsequently observed. Pulse index continuous cardiac output (PiCCO) hemodynamic monitoring and bedside echocardiography were performed, which excluded the diagnosis of cardiac pulmonary edema, and thus the diagnosis of NPE was confirmed. Goal-directed therapy by dynamic PiCCO monitoring was then implemented. In addition, levosimendan, an inotropic agent, was introduced to improve cardiac output. The patient had complete recovered from pulmonary edema and regained consciousness on day 11 of hospitalization. The current case demonstrated that PiCCO monitoring may serve a central role in the integrated management of NPE in patients with TBI. Levosimendan may be a potential medicine in treating cardiac dysfunction, along with its benefit from improving neurological function in NPE patients. PMID- 27698734 TI - C/EBP beta mRNA expression is upregulated and positively correlated with the expression of TNIP1/TNFAIP3 in peripheral blood mononuclear cells from patients with systemic lupus erythematosus. AB - CCAAT/enhancer-binding protein beta (C/EBP beta) has important roles in numerous signaling pathways. The expression of the majority of regulators and target gene products of C/EBP beta, including tumor necrosis factor alpha-induced protein 3 (TNFAIP3) and TNFAIP3-interacting protein 1 (TNIP1), are upregulated in patients with systemic lupus erythematosus (SLE). The aim of the present study was to investigate whether C/EBP beta expression is associated with SLE pathogenesis and correlates with TNIP1 and TNFAIP3 expression. Quantitative reverse transcription polymerase chain reaction analysis was used to assess the expression of C/EBP beta, TNIP1, and TNFAIP3 mRNA in peripheral blood mononuclear cells (PBMC) from 20 patients with SLE and 20 healthy controls. Spearman's rank test was used to determine the correlation between C/EBP beta expression and SLE disease activity, and that between C/EBP beta expression and TNIP1/TNFAIP3 expression in PBMCs from patients with SLE. C/EBP beta mRNA expression was markedly increased in patients with SLE compared with healthy controls. The expression of C/EBP beta was positively correlated with the SLE disease activity index and negatively correlated with the serum level of complement components C3 and C4. In addition, C/EBP beta mRNA expression was increased in PBMCs from SLE patients that were positive for antinuclear, anti-Smith and anti-nRNP antibodies, compared with the antibody negative SLE patients. Furthermore, the mRNA expression levels of C/EBP beta in patients with SLE was positively correlated with TNIP1 and TNFAIP3 expression. The results of the current study suggest that the increased expression of C/EBP beta in PBMCs and the interaction between C/EBP beta and TNIP1/TNFAIP3 may be involved in the pathogenesis of SLE. PMID- 27698736 TI - Use of deep brain stimulation for major affective disorders. AB - The multifactorial etiology of major affective disorders, such as major depression and bipolar disorder, poses a challenge for identification of effective treatments. In a substantial number of patients, psychopharmacologic treatment does not lead to effective continuous symptom relief. The use of deep brain stimulation (DBS) for treatment-resistant patients is an investigational approach that has recently produced promising results. The recent development of safer stereotaxic neurosurgery, and the combination with functional neuroimaging to map the affected brain circuits, have led to the investigation of DBS as a potential strategy to treat major mood disorders. Several independent clinical studies have recently shown that chronic DBS treatment leads to remission of symptoms in a high number of treatment-resistant patients for major depression and bipolar disorder. In conclusion, the existing proof-of-principle that DBS can be an effective intervention for treatment-resistant depression opens new avenues for treatment. However, multicenter, randomized and blind trials need to confirm efficacy and be approved after the most recent failures. Patient selection and surgical-related improvements are key issues that remain to be addressed to help deliver more precise and customized treatment. PMID- 27698735 TI - Parasitic infection as a potential therapeutic tool against rheumatoid arthritis. AB - Parasites, which are a recently discovered yet ancient dweller in human hosts, remain a great public health burden in underdeveloped countries, despite preventative efforts. Rheumatoid arthritis is a predominantly cosmopolitan health problem with drastic morbidity rates, although encouraging progress has been achieved regarding treatment. However, although various types of methods and agents have been applied clinically, their broad usage has been limited by their adverse effects and/or high costs. Sustained efforts have been exerted on the 'hygiene hypothesis' since the 1870s. The immunosuppressive nature of parasitic infections may offer potential insight into therapeutic strategies for rheumatoid arthritis, in which the immune system is overactivated. An increasing number of published papers are focusing on the preventive and/or curative effect of various parasitic infection on rheumatoid arthritis from experimental studies to large scale epidemiological studies and clinical trials. Therefore, the present review aimed to provide a general literature review on the possible beneficial role of parasitic infection on rheumatoid arthritis. PMID- 27698738 TI - Effectiveness of palliative care for non-small cell lung cancer. AB - Lung cancer is the leading cause of cancer mortality worldwide. Despite increases in the survival rate for various types of cancer over the past several decades, lung cancer remains an overwhelmingly lethal disease and the majority of patients succumb to the disease in a short period of time. A number of treatment options are available depending on the stage of lung cancer. The present review focused on palliative care and is associated with stage IIIB and IV of non-small cell lung cancer (NSCLC). Stage IIIB disease is not amenable to curative treatment and for stage IV disease, treatment is palliative in nature, with a focus on increasing survival time, controlling symptoms and improving or maintaining quality of life. Palliative treatment options include chemotherapy, radiotherapy and supportive care. The present review examines the important aspects of palliative therapy with regard to NSCLC. PMID- 27698737 TI - Pediatric rhinitis risk factors. AB - Rhinitis is a common global disorder that impacts on the quality of life of the sufferer and caregivers. Treatment for pediatric rhinitis is empirical and does not include a detailed history of the allergy triggers or allergy testing. Thus, allergen avoidance advice is not tailored to the child's sensitivities, which may result in adenoid hypertrophy. However, infant onset rhinitis, especially its relationship with respiratory viruses, remains to be further clarified. Rhinitis basically involves inflammation of the upper nasal lining, presenting typically with symptoms of runny nose (rhinorrhea), nasal blockage, and/or sneezing. While not typically fatal, it does impose significant health, psychological, and monetary burden to its sufferers, and is thus considered a global health problem. Previous findings showed that immunotherapy had significant clinical efficacy in children with allergic rhinitis. The present review article aims to highlight recent perspectives pertaining to the rhinitis risk factors especially in pediatric patients. PMID- 27698741 TI - Hospital information technology in home care. AB - The utilization of hospital information technology (HIT) as a tool for home care is a recent trend in health science. Subjects gaining benefits from this new endeavor include middle-aged individuals with serious chronic illness living at home. Published data on the utilization of health care information technology especially for home care in chronic illness patients have increased enormously in recent past. The common chronic illnesses reported in these studies were primarily on heart and lung diseases. Furthermore, health professionals have confirmed in these studies that HIT was beneficial in gaining better access to information regarding their patients and they were also able to save that information easily for future use. On the other hand, some health professional also observed that the use of HIT in home care is not suitable for everyone and that individuals cannot be replaced by HIT. On the whole it is clear that the use of HIT could complement communication in home care. The present review aims to shed light on these latest aspects of the health care information technology in home care. PMID- 27698739 TI - Metabolic syndrome in children (Review). AB - Metabolic syndrome (MetS) is a cluster of cardiometabolic risk factors, including central obesity, insulin resistance, glucose intolerance, dyslipidemia and increased blood pressure. The prevalence of MetS is on the increase worldwide owing to the epidemic of overweight and obesity. The risk of prevalence of MetS greatly increases during adulthood for those children exposed to cardiometabolic risk factors in their early lives. MetS has also been associated with liver fat accumulation in children. Elevated levels of plasma alanine aminotransferase and gamma-glutamyl transferase have been associated with liver fat accumulation. The present review aimed to expand knowledge on the clustering of cardiometabolic risk factors responsible for the widespread occurrence of metabolic disease in children. PMID- 27698740 TI - Neurological teratogenic effects of antiepileptic drugs during pregnancy. AB - Epilepsy is one of the few neurologic disorders that requires a constant treatment during pregnancy. Epilepsy affects 0.3-0.8% of pregnant women. Prescription of antiepileptic drugs (AEDs) to pregnant women with epilepsy requires monitoring and maintaining a balance between limiting seizures and decreasing fetal exposure to the potential teratogenic effects. AEDs are also commonly used for psychiatric disorders, pain disorders, and migraines. The types of malformations that can result in fetuses exposed to AEDs include minor anomalies, major congenital malformations, intrauterine growth retardation, cognitive dysfunction, low IQ, microcephaly, and infant mortality. In the present review, we analyzed and summarized the current understanding of neurological development in fetuses that are exposed to various AEDs administered to pregnant epileptic women. PMID- 27698742 TI - Blood-filled cerebrospinal fluid-enhanced pericyte microvasculature contraction in rat retina: A novel in vitro study of subarachnoid hemorrhage. AB - Previously, it was widely accepted that the delayed ischemic injury and poor clinical outcome following subarachnoid hemorrhage (SAH) was caused by cerebral vasospasm. This classical theory was challenged by a clazosentan clinical trial, which failed to improve patient outcome, despite reversing angiographic vasospasm. One possible explanation for the results of this trial is the changes in microcirculation following SAH, particularly in pericytes, which are the primary cell type controlling microcirculation in the brain parenchyma. However, as a result of technical limitations and the lack of suitable models, there was no direct evidence of microvessel dysfunction following SAH. In the present study, whole-mount retinal microvasculature has been introduced to study microcirculation in the brain following experimental SAH in vitro. Artificial blood-filled cerebrospinal fluid (BSCF) was applied to the retinal microvasculature to test the hypothesis that the presence of subarachnoid blood affects the contractile properties of the pericytes containing cerebral microcirculation during the early phase of SAH. It was observed that BCSF induced retina microvessel contraction and that this contraction could be resolved by BCSF wash-out. Furthermore, BCSF application accelerated pericyte-populated collagen gel contraction and increased the expression of alpha-smooth muscle actin. In addition, BCSF induced an influx of calcium in cultured retinal pericytes. In conclusion, the present study demonstrates increased contractility of retinal microvessels and pericytes in the presence of BCSF in vitro. These findings suggest that pericyte contraction and microvascular dysfunction is induced following SAH, which could lead to greater susceptibility to SAH-induced ischemia. PMID- 27698743 TI - Systemic and local zoledronic acid treatment with hydroxyapatite bone graft: A histological and histomorphometric experimental study. AB - In this study, the aim was to compare the relative efficacy of systemic and local zoledronic acid (ZA) on a hydroxyapatite (HA) bone graft in a rat critical-size calvarial bone defect. In total, 84 female rats were divided into four groups: Empty control (EC) group with no treatment applied; HA group, in which only HA bone graft material was used in the calvarium; and HA plus local ZA (HA+LZA) and HA plus systemic ZA (HA+SZA) groups, in which animals received ZA locally or systemically, respectively, with HA bone graft material in the calvarium. A 5-mm standardised critical-size calvarial bone defect was created with a standard trephine drill and the respective treatment was applied. Rats were sacrificed 7, 14 and 28 days later. The numbers of osteoclasts and osteoblasts, and degree of bone formation were evaluated histopathologically and histomorphometrically. Statistically significant differences were detected between the HA, HA+LZA and HA+SZA groups and the EC group for new bone formation (P<0.05). Osteoblast numbers in the HA+LZA and HA+SZA groups were significantly higher compared with those in the EC and HA groups (P<0.05). No statistically significant difference was detected between the HA+LZA and HA+SZA groups in new bone formation or osteoblast number (P>0.05). Bone formation was significantly higher in the HA group than in the EC group (P<0.05). The numbers of osteoclasts in the HA+LZA and HA+SZA groups were significantly higher than those in the groups EC and HA (P<0.05); however, there was no significant difference between groups HA+LZA and HA+SZA (P>0.05). Within the limitations of this study, systemic or local administration of ZA enhanced new bone formation with a HA bone graft in a rat critical-size calvarial defect model. PMID- 27698744 TI - Clinical evaluation of ultrasound screening in follow-up visits of infants with cerebral palsy at high risk for developmental dysplasia of the hip. AB - The aim of the study was to assess the clinical value of ultrasound screenings for the developmental dysplasia of the hip (DDH) and explore its etiology in high risk infants with cerebral palsy in follow-up visits. A group of 98 cases of infants at high-risk of cerebral palsy who received rehabilitation treatment between July, 2009 and July, 2010 were selected. Infants included 58 men and 40 women, aged <6 months and not lost to follow-up visits. Ultrasound (using Graf static inspection) screening of hips was performed and the infants with abnormalities were given clinical intervention, and 1- to 2-year-old infants were given outpatient follow-ups. The results were analyzed and there were 40 abnormal cases among the 98 cases of infants at high risk of cerebral palsy, including 18 cases of unstable hip joint, and 22 cases of DDH (12 cases of hip dysplasia, 3 cases of hip subluxation and 7 cases of hip dislocation). Early clinical intervention for infants with hip dysplasia and outpatient follow up for infants aged 1-2 years was carried out and had ischemic necrosis of femoral head, with the exception of 1 case of femoral detorsion that was poorly restored. In conclusion, the probability of DDH was higher in infants at high-risk of cerebral palsy compared to the normal infants. Hip ultrasound is a safe, simple, and effective screening method for these infants, which is of great clinical significance for an earlier diagnosis and treatment of DDH in infants with cerebral palsy. PMID- 27698745 TI - Concomitant presentation of Anderson-Tawil syndrome and myasthenia gravis in an adult patient: A case report. AB - Andersen-Tawil syndrome (ATS) is an autosomal dominant, multisystem channelopathy characterized by periodic paralysis, ventricular arrhythmias and distinctive dysmorphic facial or skeletal features. The disorder displays marked intrafamilial variability and incomplete penetrance. Myasthenia gravis (MG) is an autoimmune disorder that demonstrates progressive fatigability, in which the nicotinic acetylcholine receptor (AChR) at neuromuscular junctions is the primary autoantigen. The present study reports a rare case of a 31-year-old woman with a history of morbid obesity and periodic weakness, who presented with hemodynamic instability, cardiogenic shock and facial anomalies. Laboratory results revealed hypokalemia and an elevated anti-AChR antibody expression levels. Electrocardiography demonstrated prolonged QT-interval, ST-elevation, and subsequent third-degree atrioventricular block. Neurological examination revealed bilateral ptosis, horizontal diplopia, dysarthria and generalized weakness. No mutations in the potassium channel inwardly rectifying subfamily J member 2 gene were detected in the present case. The patient was treated with oral potassium supplementation and an acetylcholinesterase inhibitor (pyridostigmine), after which the symptoms were improved. To the best of our knowledge, the present case report was the first to describe concomitant presentation of both ATS and MG, which represents a diagnostic and therapeutic challenge. PMID- 27698746 TI - Mesenchymal stem cells with irreversibly arrested proliferation stimulate decidua development in rats. AB - Stem cell transplantation, which is based on the application of mesenchymal stem/stromal cells (MSCs), is a rapidly developing approach to the regenerative therapy of various degenerative disorders characterized by brain and heart failure, as well as skin lesions. In comparison, the use of stem cell transplantations to treat infertility has received less attention. One of the causes of miscarriages and fetal growth delay is the loss of the decidual reaction of endometrial cells. The present study modeled decidualization processes in pseudopregnant rats. For cell transplantation experiments, the rats were transplanted with MSCs established from endometrial fragments in menstrual blood (eMSCs). These cells express common MSC markers, are multipotent and are able to differentiate into various tissue lineages. Cell therapy frequently requires substantial cell biomass, and cultivation of MSCs may be accompanied by significant changes to their properties, including malignant transformation. In order to minimize the potential for malignant transformation, the proliferation of eMSCs was irreversibly suppressed by irradiation and mitomycin C treatment. Transplantation of the rats with viable, non-proliferating eMSCs stimulated the development of all elements of decidual tissue. Conversely, transplantation of the rats with cells killed using 95% ethanol did not result in the development of decidual tissue. The present study demonstrated the potential for applying eMSCs to the cellular therapy of infertility associated with endometrial disorders characterized by decidualization insufficiency and implantation failure. In addition, the transplantation of viable but non-proliferating cells ensured that their oncogenic potential was limited. PMID- 27698747 TI - Co-expressed differentially expressed genes and long non-coding RNAs involved in the celecoxib treatment of gastric cancer: An RNA sequencing analysis. AB - The aim of the present study was to investigate the mechanisms of long non-coding RNAs (lncRNAs) in a gastric cancer cell line treated with celecoxib. The human gastric carcinoma cell line NCI-N87 was treated with 15 uM celecoxib for 72 h (celecoxib group) and an equal volume of dimethylsulfoxide (control group), respectively. Libraries were constructed by NEBNext Ultra RNA Library Prep kit for Illumina. Paired-end RNA sequencing reads were aligned to a human hg19 reference genome using TopHat2. Differentially expressed genes (DEGs) and lncRNAs were identified using Cuffdiff. Enrichment analysis was performed using GO function package and KEGG profile in Bioconductor. A protein-protein interaction network was constructed using STRING database and module analysis was performed using ClusterONE plugin of Cytoscape. ATP5G1, ATP5G3, COX8A, CYC1, NDUFS3, UQCRC1, UQCRC2 and UQCRFS1 were enriched in the oxidative phosphorylation pathway. CXCL1, CXCL3, CXCL5 and CXCL8 were enriched in the chemokine signaling and cytokine-cytokine receptor interaction pathways. ITGA3, ITGA6, ITGB4, ITGB5, ITGB6 and ITGB8 were enriched in the integrin-mediated signaling pathway. DEGs co expressed with lnc-SCD-1:13, lnc-LRR1-1:2, lnc-PTMS-1:3, lnc-S100P-3:1, lnc AP000974.1-1:1 and lnc-RAB3IL1-2:1 were enriched in the pathways associated with cancer, such as the basal cell carcinoma pathway in cancer. In conclusion, these DEGs and differentially expressed lncRNAs may be important in the celecoxib treatment of gastric cancer. PMID- 27698748 TI - IL-35 improves Treg-mediated immune suppression in atherosclerotic mice. AB - Interleukin (IL)-35 is an anti-inflammatory cytokine that may have a protective role in atherosclerosis (AS). However, the exact role of IL-35 in the disease, and the etiology of AS, remain incompletely understood. The present study aimed to investigate whether exogenous IL-35 was able to attenuate the formation of atherosclerotic lesions in apoE-/- mice, and analyze alterations in the expression levels of forkhead box protein 3 (Foxp3) in peripheral blood and the lesions during the progression of AS. ApoE-/- mice were randomly divided into two groups that received either a basal diet (negative control group) or a high-fat diet (HFD) for 4 weeks. The HFD group was further subdivided into groups that received IL-35, atorvastatin or no treatment for 12 weeks. Diagnostic enzyme assay kits were applied for the detection of plasma lipids, and hematoxylin and eosin staining was used to analyze the severity of atherosclerotic lesions in apoE-/- mice. Immunohistochemistry and flow cytometry were performed to analyze the expression of Foxp3 in the plasma and atherosclerotic plaques. As compared with the negative control group, the plasma lipids were significantly increased, and the lesions were obviously formed, in the HFD groups. Furthermore, the area of the lesion was reduced in IL-35- and atorvastatin-treated groups, as compared with the AS control group. In addition, Foxp3 expression was upregulated in the plasma and lesions of the IL-35- and atorvastatin-treated groups, as compared with the AS control group. The present study demonstrated that IL-35 improved Treg-mediated immune suppression in atherosclerotic mice, thus suggesting that IL 35 may be a novel therapeutic target for AS. PMID- 27698749 TI - Randomized, double-blind, placebo-controlled superiority trial of the Yiqigubiao pill for the treatment of patients with chronic obstructive pulmonary disease at a stable stage. AB - In traditional Chinese medicine (TCM), the Yiqigubiao pill is commonly used to enhance physical fitness. The current clinical trial was designed to evaluate the efficacy and safety of the Yiqigubiao pill as an adjuvant therapy for patients with stable chronic obstructive pulmonary disease (COPD). The current trial was a randomized, double-blind, placebo-controlled superiority trial. The participants were recruited from outpatients at the Traditional Chinese Medicine Hospital affiliated with Xinjiang Medical University (Urumqi, China) between February and September 2012. All participants were patients with stable COPD that were randomized to the Yiqigubiao pill (YQGB; n=84) or placebo (Pb; n=87) groups. The occurrences of acute exacerbation (AE) of COPD during the trial were recorded. Lung function value assessments, scoring of life quality and exercise endurance, arterial blood gas analysis and serum inflammatory cytokines level determination were performed prior to and throughout the study. A total of 139 participants completed the intervention and 132 participants completed the study. The interval between the initial intervention and the first AECOPD was greater in the YQGB group compared with the Pb group (P<0.01). The incidence rate of AECOPD was lower in the YQGB group than in the Pb group (P<0.01). Subsequent to the intervention or at the end of the study, the 6-min walking distance difference was longer in the YQGB group compared with the Pb group (P<0.01). The scores reflecting life quality decline became lower in the YQGB group (P<0.01). The serum levels of proinflammatory factors were downregulated to a greater extent in the YQGB group compared with the Pb group. Thus, the Yiqigubiao pill is an efficient and safe adjuvant therapy for the treatment of stable patients with COPD. PMID- 27698750 TI - Effects of phacoemulsification and intraocular lens implantation combined with ciliarotomy in the treatment of angle-closure glaucoma with cataract. AB - The aim of the present study was to examine the effects of phacoemulsification and intraocular lens implantation combined with ciliarotomy in the treatment of angle-closure glaucoma with cataract in the elderly. A total of 68 patients were consecutively selected and divided into the control group with 33 cases (48 eyes) and the observation group with 35 cases (53 eyes). Cataract surgery combined with trabeculectomy was performed on the patients in the control group and phacoemulsification cataract extraction combined with ciliarotomy was performed on the subjects in the observation group, to compare postoperative effects and complications. Following surgery, the visual acuity of patients in the two groups significantly improved, intraocular pressure decreased, and improvement of the observation group was more evident (P<0.05). Following surgery, the depth of central anterior chamber and width of chamber angle of patients in two groups was increased, and improvement of the observation group was significantly more evident (P<0.05). Additionally, the incidence of complications, including corneal swelling, shallow of anterior chamber, fibrinous exudate in iris, and filtering bleb leaking and following cataract removal, of patients in the observation group was significantly reduced compared to the control group (P<0.05). In summary, the results of the present study show that, phacoemulsification and intraocular lens implantation combined with ciliarotomy in the treatment of angle-closure glaucoma with cataract in the elderly is a safe and effective method and should be applied in the clinic. PMID- 27698751 TI - Effect of adefovir dipivoxil on T cell immune function in the treatment of chronic hepatitis B and hepatocirrhosis. AB - The aim of the present study was to investigate the T cell immune function in chronic hepatitis B hepatocirrhosis patients at the compensated and decompensated stage following treatment with adefovir dipivoxil. A total of 104 patients diagnosed with hepatitis B hepatocirrhosis during the period from October 2013 to October 2014 were enrolled in the study. Among the cases, there were 56 cases at compensated stage, and another 48 at decompensated stage. Adefovir dipivoxil was administered for antiviral therapy (10 mg/time, 1 time/day, for a total of 24 weeks), and we compared the virus disappearance rate, liver function improvement and T cell immune function between the two groups before and after treatment. The difference between the virus disappearance rate in the two groups was not statistically significant (P>0.05). The decreased level of ALT decrease in the compensated group was significantly higher than that in the decompensated group, while the increased level of albumin in the compensated group was significantly higher as well. The differences showed statistical significance (P<0.05). After treatment, the level of CD4+ and CD4+/CD8+ ratio were higher than before treatment, while the level of CD8+ was lower after treatment than before treatment in the two groups. The differences all showed statistical significance (P<0.05). The CD4+CXCR5+ T follicular helper (TFH) cell level in the two groups was higher after treatment, as was interleukin-2 and interferon-gamma. The differences all showed statistical significance (P<0.05). As for comparison between groups, the difference had no statistical significance (P>0.05). Adefovir dipivoxil treatment can improve T cell immune function at the compensated and decompensated stages in chronic hepatitis B hepatocirrhosis patients. This may be associated with virus disappearance and liver function improvement. PMID- 27698752 TI - Serum biomarkers combined with uterine artery Doppler in prediction of preeclampsia. AB - First-trimester screening may be a major advantage over a second-trimester approach since it opens prospects for early and more efficient interventions. The aim of the current study was to evaluate whether the measurement of maternal serum inhibin A, activin A and placental growth factor (PlGF) at three to four months gestation with the second-trimester uterine artery pulsatility index (PI) are useful in predicting preeclampsia in a group of nulliparous women. All the patients also underwent uterine artery Doppler examination to measure the PI at 22-24 weeks gestation. Inhibin A, activin A and PlGF were measured using an ELISA by an examiner who was blinded to the pregnancy outcome. Thirty-eight cases with preeclampsia and 100 controls were analyzed. Second-trimester uterine artery PI and marker levels were expressed as multiples of the median (MoM). The uterine artery PI was increased in pregnancies with preeclampsia compared with controls. In pregnancies that developed preeclampsia, the uterine artery PI was increased (1.61+/-0.047 vs. 1.02+/-0.049, P<0.001), as was the level of inhibin A (1.72+/ 0.023 vs. 1.03+/-0.063, P<0.001) and the level of activin A (1.68+/-0.38 vs. 1.06+/-0.42, P<0.001) compared with the controls. In contrast, the level of PlGF was decreased in pregnancies that developed preeclampsia compared with the controls (0.69+/-0.23 vs. 1.00+/-0.26, P<0.001). A combination of activin A, PlGF and uterine artery PI gave an AUC of 0.915 (95% CI, 0.812-0.928; P<0.001) with a sensitivity of 91% at a specificity of 82%. In our study, we demonstrated that both serum inhibin A and activin A levels were increased, while the PlGF level was decreased in the early second-trimester in women who developed preeclampsia. PMID- 27698753 TI - Local application of low-dose insulin in improving wound healing after deep burn surgery. AB - The clinical effects of local application of low-dose insulin in improving wound healing after deep burn self-skin transplantation surgery were examined. Fifty eight patients with deep burns were selected and randomly divided into 3 groups. In the blank control group, normal saline was injected to the subcutaneous tissue of wounds; in large dose insulin group, 1.0 u long-term suspended zinc insulin was locally injected; and in the low-dose insulin group, 0.1 u long-term suspended zinc insulin was locally injected. The healing effects were compared. After 7 and 14 days of treatments, wound surface area in the low-dose group was significantly smaller than in the other groups, and differences were statistically significant (P<0.05); wound healing duration and infection rate for patients in the low-dose group were significantly lower, class A healing rate was significantly improved, and the differences were statistically significant (P<0.05). Insulin resistance index (HOMA-IR) in the low-dose group was significantly lower, insulin secretion index (HOMA-beta) and the insulin sensitivity index (HOMA-ISI) significantly increased. The expression levels of vascular endothelial growth factor and tumor necrosis factor-alpha in local tissue for the low-dose group were significantly higher than those in the other two groups. Differences were statistically significant (P<0.05). In conclusion, local application of low-dose insulin can effectively improve wound healing after deep burn surgeries. PMID- 27698754 TI - Oral paracetamol vs. oral ibuprofen in the treatment of symptomatic patent ductus arteriosus in premature infants: A randomized controlled trial. AB - The aim of the present study was to analyze the changes of plasma and urinary prostaglandin E2 (PGE2) levels in preterm infants with symptomatic patent ductus arteriosus (sPDA) treated with oral ibuprofen and acetaminophen. A total of 87 preterm infants with sPDA admitted to the Neonatal Ward of the Affiliated Xuzhou Hospital of Medical College of Southeast University from October, 2012 to June, 2015 were selected and randomly divided into the ibuprofen group (n=43, 10 mg/kg ibuprofen administered orally as initial dose, followed by 5 mg/kg during the first 24 and 48 h later) and acetaminophen group (n=44, 15 mg/kg acetaminophen administered orally once every 6 h for three days). The levels of plasma and urinary PGE2 in the two groups were estimated before and after treatment. The treatment of sPDA infants with ibuprofen (ibuprofen group) or acetaminophen (acetaminophen group) caused a significant decrease in the plasma and urinary PGE2 levels in comparison with plasma and urinary PGE2 levels before treatment (P<0.05). Furthermore, plasma and urinary PGE2 levels in the acetaminophen group (45.0+/-36.9 ng/l) were significantly lower than those in the ibuprofen group (73.5+/-44.8 ng/l, P=0.002). The arterial duct closure rate was similar between the acetaminophen [31 (70.5%)] and ibuprofen groups [33 (76.7%), P=0.506]. The incidence of oliguria was less among sPDA infants of the acetaminophen group [1 (2.3%)] than observed among the sPDA infants of the ibuprofen group [6 (14.0%)]; however, this difference was not statistically significant (P=0.108). Additionally, the incidences of fecal occult blood positive rate, intraventricular hemorrhage, neonatal necrotizing enterocolitis and bronchopulmonary dysplasia were distributed similarly in the ibuprofen and acetaminophen groups (P>0.05). The levels of platelet, serum creatinine and alanine transaminase showed no significant changes between the ibuprofen and acetaminophen groups (P>0.05). Following treatment with ibuprofen or acetaminophen, the extent of decrease of plasma and urinary PGE2 was significantly higher among sPDA infants with oliguria (135.0+/-38.0 ng/l) than that observed in sPDA infants without oliguria (52.5+/-37.0 ng/l) (P=0.01). The study also found a significant correlation between plasma and urinary PGE2 levels (r=0.648, P=0.01) and the coefficient of variation of urinary PGE2 (0.427) was less than that of plasma PGE2 (0.539). The clinical efficacy of oral ibuprofen and acetaminophen in the treatment of preterm infants with sPDA was similar with low adverse events, whereas acetaminophen-induced PGE2 levels were less than the levels observed in the ibuprofen-treated group. The incidence of oliguria was also lower in the acetaminophen group compared to the ibuprofen group. In addition, monitoring urinary PGE2 levels was more suitable because of its non invasiveness in the clinical setting than monitoring of plasma PGE2 in preterm infants with sPDA. PMID- 27698755 TI - LSKL peptide alleviates subarachnoid fibrosis and hydrocephalus by inhibiting TSP1-mediated TGF-beta1 signaling activity following subarachnoid hemorrhage in rats. AB - Hydrocephalus has been demonstrated to be an independent risk factor for poor outcomes in patients with subarachnoid hemorrhage (SAH). Blockage of cerebrospinal fluid (CSF) flow and drainage is widely considered to play a vital role in communicating hydrocephalus, possibly due to subarachnoid fibrosis. A previous study indicated that transforming growth factor-beta1 (TGF-beta1), a key fibrogenic factor, is significantly increased in the CSF following SAH, implying a pivotal role in the development of chronic hydrocephalus. To investigate whether LSKL peptide, a small molecular peptide and competitive antagonist for TGF-beta1, protects against subarachnoid fibrosis and hydrocephalus after SAH, a two-hemorrhage injection model of SAH was created in Sprague-Dawley rats. LSKL (1 mg/kg) was administered intraperitoneally immediately following the first intravenous injection of blood in the SAH model, with repeated injections of LSKL every 12 h until sacrifice. Thrombospondin-1 (TSP1), TGF-beta1, p-Smad2/3, collagen I and pro-collagen I c-terminal propeptide levels were assessed via western blotting and ELISA. Lateral ventricular index, Masson staining and Morris water maze tests were employed to evaluate subarachnoid fibrosis, hydrocephalus and long-term neurological function following SAH. It was found that the LKSL peptide readily crossed the blood brain barrier, was protective against subarachnoid fibrosis, attenuated ventriculomegaly and effectively suppressed hydrocephalus. In addition, the results indicated that the protective effects of the LSKL peptide were achieved via the inhibition of TGF-beta1 activity and subsequent Smad2/3 signaling. Importantly, the LSKL peptide may improve long-term neurocognitive deficits after SAH. In conclusion, the LSKL peptide suppresses subarachnoid fibrosis via inhibition of TSP1-mediated TGF-beta1 activity, prevents the development of chronic hydrocephalus and improves long-term neurocognitive defects following SAH. PMID- 27698756 TI - Application of levator veli palatini retropositioning combined with Buccinator myomucosal island flap for congenital cleft palate. AB - Congenital cleft palate causes a serious obstacle to children with regard to language and eating function. The aim of the current study was to examine the clinical application of a type of palatoplasty that has a reduced impact on the maxillary growth and good function in velopharyngeal competence. A total of 37 patients with cleft palate were treated with levator veli palatini retropositioning combined with Buccinator myomucosal island flap. The patients were successfully treated in the first phase and were followed up for 1-3 years. Speech intelligibility was satisfactory and no fistula occurred. In conclusion, the results suggested that levator veli palatini retropositioning combined with the Buccinator myomucosal island flap may restore normal anatomic structure and location of the levator veli palatini, obtain good velopharyngeal competence, and decrease the incidence rate thereof. Thus, levator veli palatini retropositioning combined with the Buccinator myomucosal island flap is a functional procedure for cleft palate repair. PMID- 27698757 TI - Role of the renal sympathetic nerves in renal sodium/potassium handling and renal damage in spontaneously hypertensive rats. AB - Renal sympathetic nerve activity has an important role in renal disease associated hypertension and in the modulation of fluid homeostasis. In the present study, changes in renal function and renal sodium/potassium handling were investigated in groups of 12-week-old male, spontaneously hypertensive rats with renal denervation (RDNX group) or sham denervation (sham group). The RDNX group excreted significantly more sodium than the sham group during the 2-week observation period (P<0.05). Following bilateral renal denervation, the fractional lithium excretion was elevated in the RDNX group compared with the sham group, but no significant effect was observed of renal denervation on the fractional distal reabsorption rate of sodium or the fractional excretion of potassium. Furthermore, the glomerular injury score and the wall-to-lumen ratio of the interlobular artery were significantly lower in the RDNX group than in the sham group (P<0.05). In conclusion, the present study indicates an involvement of the renal sympathetic nerves in the regulation of renal tubular sodium reabsorption in spontaneously hypertensive rats and in the renal damage associated with hypertension. PMID- 27698758 TI - Mucosa-reparing and microbiota-balancing therapeutic effect of Bacillus subtilis alleviates dextrate sulfate sodium-induced ulcerative colitis in mice. AB - Gut microbiota composition of patients with ulcerative colitis (UC) is markedly altered compared with healthy individuals. There is mounting evidence that probiotic therapy alleviates disease severity in animal models and patients with inflammatory bowel disease (IBD). Bacillus subtilisis, as a probiotic, has also demonstrated a protective effect in IBD. However, the therapeutic mechanism of its action has yet to be elucidated. In the present study, a dextrose sulfate sodium (DSS)-induced UC mouse model was used to investigate the role of B. subtilis in the restoration of gut flora and determine its effective dose. Mucosal damage was assessed by performing alcian blue staining, cytokine levels were analyzed by ELISA and microbiota composition was investigated using 454 pyrosequencing to target hypervariable regions V3-V4 of the bacterial 16S ribosomal RNA gene. The results demonstrated that a higher dose B. subtilisis administration ameliorated DSS-induced dysbiosis and gut inflammation by balancing beneficial and harmful bacteria and associated anti- and pro inflammatory agents, thereby aiding intestinal mucosa recovery from DSS-induced injuries. These findings indicate that choosing the correct dose of B. subtilis is important for effective UC therapy. The present study also helped to elucidate the mechanisms of B. subtilis action and provided preclinical data for B. subtilis use in UC therapy. PMID- 27698759 TI - Delayed protective effect of telmisartan on lung ischemia/reperfusion injury in valve replacement operations. AB - The present study aimed to investigate the delayed protective effect of telmisartan on lung ischemic/reperfusion injury in patients undergoing heart valve replacement operations. In total, 180 patients diagnosed with rheumatic valve diseases were randomly divided into the telmisartan (T), captopril (C) and placebo (P) groups. In the telmisartan group, the patients were pretreated with telmisartan (1 mg/kg/day), at the time period 96-48 h before the operation, whereas in the C group, the patients were treated with captopril (1 mg/kg/day) at the time period 96-48 h prior to the operation control group. Each drug treatment group included a corresponding placebo treatment. The variables pulmonary vascular resistance (PVR) and A-aDO2 were measured prior to CPB and at 1, 3, 6 and 12 h after CPB. Pulmonary neutrophil (PMN) count in the left and right atrium blood as well as SOD malondialdehyde (MDA), NO, angiotensin II (AngII) value in the left atrium blood, were measured 30 min prior to and after CPB. The PVR parameters of the telmisartan and captopril groups were significantly lower than those of the placebo group (P<0.05). The A-aDO2 values in the telmisartan and captopril groups were significantly lower than those in the placebo group at 1, 3 and 6 h following CPB treatment. The difference between the right and left atrium blood PMN was significantly lower in the telmisartan and captopril intervention groups compared to that in the placebo group 30 min following CPB treatment. The left atrium blood SOD and NO values were significantly higher, whereas the MDA value was significantly lower in the telmisartan group compared to the control group 30 min following CPB treatment. As for AngII, there was no difference between the C and T groups, compared with the P group. In the two groups 30 min after treatment with CPB, 24 patients experienced varying degrees of cough, with the telmisartan group showing a significant difference (P<0.05). The hospitalization time was compared in the three groups of patients and it was found to be significantly shorter in the telmisartan group than the captopril and placebo groups (P<0.05). In conclusion, it was found that for the time period 96 48 h before heart valve replacement operations telmisartan (1 mg/kg/day) delayed the protective effect on lung ischemia/reperfusion injury in patients with rheumatic valve diseases. The results of the present study indicated that the protective effect may be associated with the increment of endogenetic NO and the enhanced ability against lipid peroxidation. PMID- 27698760 TI - Part of plasmapheresis with plasma filtration adsorption combined with continuous hemodiafiltration in the treatment of severe acute liver failure. AB - The present study is a retrospective analysis of 11 cases with severe acute liver failure combined with multiple organ dysfunction syndrome (MODS) performed during the period June, 2012 to December, 2014. After part of plasmapheresis with plasma filtration adsorption combined with continuous hemodiafiltration treatment, good curative effects were obtained and the main clinical symptoms and biochemical index were significantly improved. Following treatment, 8 of the 11 patients survived at a survival rate of 72.7%, and 3 patients succumbed with a mortality of 27.3%. The results suggested that part of plasmapheresis with plasma filtration adsorption combined with continuous venovenous hemodiafiltration (CVVHDF) treatment is beneficial in the removal of metabolites and toxins. Additonally, it can effectively improve liver function and clinical symptoms, improve hepatic encephalopathy, correct the disorder of internal environment, and improve the prognosis of patients. PMID- 27698761 TI - Aminoglycoside antibiotics for NIH category II chronic bacterial prostatitis: A single-cohort study with one-year follow-up. AB - Although fluoroquinolones are first-line agents for the treatment of National Institutes of Health (NIH) category II chronic bacterial prostatitis (CBP), therapy with these agents is not always feasible due to the increasing worldwide resistance of causative uropathogens. New therapeutic options are urgently required, as drugs such as beta-lactam antibiotics distribute poorly to prostatic sites of infection and trimethoprim therapy is often unfeasible due to high resistance rates. The present study aimed to analyze the efficacy of aminoglycosides, administered to a cohort of 78 patients affected by fluoroquinolone-resistant CBP, or excluded from fluoroquinolone therapy due to various contraindications. Patients received netilmicin (4.5 mg/kg, once-daily, intramuscular), combined or not with a beta-lactam antibiotic, for 4 weeks. Follow-up visits were scheduled 6 and 12 months after the end of treatment. Fifty five out of 70 patients (78.6%) showed eradication of the causative pathogen, and a significant reduction of the NIH-Chronic Prostatitis Symptom Index (NIH-CPSI) total score from a baseline median value of 21 to 14 at the end of therapy, and to 9 and 8 at 6-month and 12-month follow-up assessments, respectively. The pain, voiding and quality of life subdomains of the NIH-CPSI decreased accordingly. In 15 patients showing persistence of infection, NIH-CPSI total and subdomain scores did not decrease at the end of therapy. Additional clinical parameters, such as the urinary peak flow rate, percentage voided bladder, serum prostate-specific antigen concentration, International Prostate Symptom Score and prostate volume improved significantly only in the group of patients in which the infection was eradicated. Therapy was well tolerated, and genetic testing for deafness predisposing mitochondrial mutations allowed safer administration of aminoglycosides. These results suggest that aminoglycosides may become a therapeutic alternative for the treatment of CBP. These findings should be further validated in a randomized-controlled setting. PMID- 27698762 TI - TFP5 prevents 1-methyl-4-phenyl pyridine ion-induced neurotoxicity in mouse cortical neurons. AB - The present study aimed to investigate the protective effect of a modified p5 peptide, TFP5, on 1-methyl-4-phenyl pyridine ion (MPP+)-induced neurotoxicity in cortical neurons and explore the therapeutic effect of TFP5 on Parkinson's disease (PD). MPP+ was applied to a primary culture of mouse cortical neurons to establish the cell model of PD. Neurons were divided into four groups: Control, model (MPP+), scrambled peptide (Scb) (Scb + MPP+) and TFP5 (TFP5 + MPP+) groups. Pretreatment with Scb or TFP5 was applied to the latter two groups, respectively, for 3 h, while phosphate-buffered saline was applied to the control and model groups. MPP+ was then applied to all groups, with the exception of the control group, and neurons were cultured for an additional 24 h. Neuron viability was evaluated using a Cell Counting kit-8 (CCK8) assay. To explore the mechanism underlying the protective effects of TFP5, the expression levels of p35, p25 and phosphorylated myocyte enhancer factor 2 (p-MEF2D) were determined by western blotting. Fluorescence microscopy showed that TFP5 was able to pass through cell membranes and distribute around the nucleus. CCK8 assay showed that neuronal apoptosis was dependent on MPP+ concentration and exposure time. Cell viability decreased significantly in the model group compared with the control group (55+/ 7 vs. 100+/-0%; P<0.01), and increased significantly in the TFP5 group compared with the model group (98+/-2 vs. 55+/-5%; P<0.01) and Scb group (98+/-2 vs. 54+/ 4%; P<0.01). Scb exhibited no protective effect. Western blotting results showed that MPP+ induced p25 and p-MEF2D expression, TFP5 and Scb did not affect MPP+ induced p25 expression, but TFP5 reduced MPP+-induced p-MEF2D expression. In summary, TFP5 protects against MPP+-induced neurotoxicity in mouse cortical neurons, possibly through inhibiting the MPP+-induced formation and elevated kinase activity of a cyclin-dependent kinase 5/p25 complex. PMID- 27698763 TI - Observation on therapeutic efficacy of rt-PA intravenous thrombolysis combined with compound anisodine injection on central retinal artery occlusion. AB - The aim of the present study was to observe the clinical efficacy and safety of recombinant tissue plasminogen activator (rt-PA) combined with compound anisodine in treating central retinal artery occlusion (CRAO). Forty-eight patients diagnosed with CRAO were randomly divided into a treatment group (24 cases) and a control group (24 cases). For the control group, nitroglycerin, 654-2, methazolamide, puerarin and compound anisodine were used for the treatment, along with oxygen, massage and other conventional treatments. Besides conventional therapy, the treatment group was also given intravenous rt-PA thrombolysis. Visual acuity, fundus oculi, visual field changes were taken as indicators for efficacy evaluation. It was found that the total effective rate of the control group was 70.83%, while that for the treatment group was 91.67%, and the comparative difference between the two groups was of statistical significance (p<0.05). The visual field defect of the control group after treatment was approximately 74.26+/-12.91%, and the visual field defect of the treatment group after treatment approximately 35.08+/-16.33%; thus, the comparative difference was statistically significant (p<0.01). The comparative difference of the original contents of fibrous protein in blood in the treatment group before and after treatment was statistically significant (p<0.01). In conclusion, the result show that intravenous thrombolysis with rt-PA combined with compound anisodine is safe and effective in treating CRAO, which can significantly improve the prognosis of patients. PMID- 27698764 TI - Protective effects of dexmedetomidine combined with flurbiprofen axetil on remifentanil-induced hyperalgesia: A randomized controlled trial. AB - High dosages of intra-operative remifentanil are associated with opioid-induced hyperalgesia (OIH). The aim of the present study was to investigate the effect of combined dexmedetomidine and flurbiprofen axetil treatment on remifentanil induced hyperalgesia. Patients with an American Society of Anesthesiologists physical status of I-II who were diagnosed with hysteromyoma and scheduled for laparoscopic assisted vaginal hysterectomy (LAVH) were randomly divided into three groups. Group hyperalgesia (Group H, n=29) received intra-operative remifentanil, Group hyperalgesia and dexmedetomidine (Group HD, n=28) received remifentanil and a continuous infusion of dexmedetomidine, and Group hyperalgesia, dexmedetomidine and flurbiprofen axetil (Group HDF, n=29) received remifentanil, flurbiprofen axetil and dexmedetomidine. Mechanical pain thresholds were measured during the preoperative visit and postoperatively at 1, 6 and 24-h time points. Visual analog scale (VAS) scores, time to analgesic requirement, total sufentanil consumption and side effects were assessed postoperatively. Mechanical pain threshold at the incision site was significantly lower in Group H compared with Groups HD and HDF (both P<0.05), and significantly higher in Group HDF than in Group HD (P<0.05). The area of secondary hyperalgesia at the incision site was greater in Group H than in the other two groups (both P<0.05), and significantly smaller in Group HDF compared with Group HD (P<0.05). VAS scores and total sufentanil consumption were significantly higher in Group H compared with the other two groups (both P<0.05), and were significantly lower in Group HDF compared with Group HD (P<0.05). Dexmedetomidine combined with flurbiprofen axetil exhibits synergetic effects in the prevention of remifentanil-induced hyperalgesia in patients undergoing LAVH. PMID- 27698765 TI - Association of genetic polymorphisms of GALNT3 and VDR with osteoporosis in postmenopausal women. AB - The correlation of genetic polymorphisms of GALNT3 and vitamin D receptor (VDR) with osteoporosis in postmenopausal women was investigated. A total of 1,212 cases of postmenopausal patients diagnosed with osteoporosis (observation group) and 404 cases of postmenopausal women without osteoporosis (control group) were selected. Dual-energy X-ray absorptiometry was used for measurement of bone mineral density (BMD) of lumbar vertebrae L2-4, proximal femoral neck and total hip, and classifications were made. TaqMan genotyping technology was employed to examine tag single-nucleotide polymorphism (tagSNP) of GALNT3 and VDR and the correlation of tagSNP with bone turnover markers (BTMs) and serum calcium and phosphorous levels was analyzed. The multiple logistic regression analysis was used to screen risk factors for osteoporosis. A comparison of age and menopause time of the two groups, yielded no statistical significance difference (P>0.05). BMD and T values of the lumbar vertebrae, femoral neck and total hip in the observation group were significantly lower than those in the control group, and the differences were statistically significant (P<0.05). A comparison of the degree of osteoporosis, yielded statistically significant differences (P<0.05). The proportion of tagSNP of 5 loci in GALNT3 and 3 loci in VDR in the observation group was significantly higher than that in the control group, and the differences were of statistical significance (P<0.05). Levels of 25-OHD3, beta CTX, P1NP and serum calcium in the observation group were lower than those in the control group and the level of serum phosphorus in the observation group was higher than that in the control group, and all of these results were statistically significant (P<0.05). The result of the correlation analysis revealed that rs1425000 and rs757343 were negatively correlated with BTM and serum calcium and phosphorus levels (P<0.05). The result of the regression analysis revealed that 8 tagSNPs were independent risk factors for osteoporosis. Genetic polymorphisms of GALNT3 and VDR were closely associated with osteoporosis in postmenopausal women. PMID- 27698766 TI - Establishment of ApoE-knockout mouse model of preeclampsia and relevant mechanisms. AB - In the present study, we established an ApoE-knockout mouse model of preeclampsia to examine the role of vascular endothelial injury associated with abnormal lipid metabolism in the pathogenesis of preeclampsia. To establish the ApoE-knockout homozygous (ApoE-/-) and heterozygous (ApoE+/-) mouse model, mice were mated with the same genotype and orbital blood on day 19 of conception was collected. The progeny mice were assigned into 3 groups: ApoE-/, ApoE+/- and wild-type (WT) groups. Total cholesterol, triglyceride, low-density and high-density lipoprotein were measured in the serum at the end of conception. During conception, the systolic blood pressure of caudal artery was measured every 4 days. Using bicinchoninic acid protein assay, urinary protein and creatinine ratio was measured with a creatinine kit. We observed the pathological changes of glomerular filtration membrane and macroscopic/microscopic morphological changes of placenta by hematoxylin and eosin (H&E) staining and transmission electron microscope. Take fetal mouse through cesarean section on 19th day, measure the birth weight and placental weight of fetal mouse. Using ELISA we measured the expression levels of toll-like receptor 4 (TLR4) and soluble fms-like tyrosine kinase-1 (sFlt-1). Our results showed that the differences in serum lipid levels were not statistically significant (P>0.05). The mean systolic blood pressure, urinary protein and creatinine in ApoE-/- group were significantly higher than ApoE+/- group and WT group (P<0.05). Thickening and edema of glomerular filtration membrane, capillary thrombosis, significant edema and necrosis of placental villous stroma were observed in ApoE-/- group. No significant change was detected in the ApoE+/- or WT group. The TLR4 and sFlt-1 expression levels in ApoE-/- group were significantly higher than ApoE+/- and WT group (P<0.05). We concluded that ApoE-knockout mouse could simulate the pathologic process of preeclampsia, while the changes in serum lipids were not noteworthy, thus the pathogenesis of preeclampsia may be mediated by TLF4 and sFlt-1. PMID- 27698767 TI - National trends in carotid endarterectomy and stenting in Korea from 2004 to 2013. AB - Stroke imposes a substantial clinical and socioeconomic burden. Carotid endarterectomy (CEA) or carotid artery stenting (CAS) are proven procedures in stroke prevention for the lesions of extracranial carotid disease. Although several studies have addressed national trends regarding carotid revascularization in Western countries, limited data is available with respect to the Korean population. The aim of the present study was to identify the national trend in carotid revascularization in Korea over the previous decade. A serial, cross-sectional study was conducted with the use of time trends to analyze patients undergoing carotid revascularization using CEA and CAS between 2004 and 2013. Health Insurance Review and Assessment Service data was used. The present study endeavored to analyze trends in the number of CEA and CAS procedures for the treatment of extracranial carotid disease in Medicare beneficiaries. A linear by-linear association was performed to determine the changes of carotid revascularization for the aforementioned period. A total of 23,142 patients received carotid revascularization between 2004 and 2013. CEA was performed in 4,012 and CAS in 19,130 patients. The rate of total carotid revascularization per 1,000,000 Medicare beneficiaries substantially increased during the study period from 22 procedures in 2004 to 57 in 2013 (risk ratio (RR), 2.59; 95% confidence interval (CI), 1.58-4.24; P=0.001). CAS increased from 18 procedures in 2004, to 45 in 2013 (RR, 2.50; 95% CI; 1.45-4.32; P=0.001). In addition, the number of CEA procedures performed per 1,000,000 Medicare beneficiaries increased from four procedures in 2004, to 11 in 2013 (RR, 2.75; 95% CI, 0.88-8.64; P=0.08). In conclusion, total carotid revascularization increased by 255% during the previous 10 years in Korea. This increase predominantly resulted from the 249% increase of CAS. The number and population-based rates of carotid revascularization remained low, as compared with Western countries. PMID- 27698769 TI - MicroRNA-129-5p inhibits vascular smooth muscle cell proliferation by targeting Wnt5a. AB - Aberrant smooth muscle cells (SMCs) play important roles in the formation of abdominal aortic aneurysm (AAA). Although the molecular mechanism of AAA formation has been investigated, there is a lack of understanding concerning the role of microRNAs (miRNAs) in AAA, which the current study aimed to address. Firstly, miRNA array analysis was performed in order to compare the miRNA profiles in a mouse model of AAA with those in normal control mice, and differentially expressed miRNAs were identified. miR-129-5p was selected for further analysis, and was used to transfect human SMCs. The results of an MTT assay revealed that miR-129-5p inhibited the proliferation of SMCs, and flow cytometry indicated that apoptosis was induced. Bioinformatic analysis predicted that Wnt5a was the potential target gene of miR-129-5p, and this was verified by luciferase assay. In summary, miR-129-5p inhibits cellular proliferation, induces apoptosis and modulates the Wnt5a signaling pathway in SMCs. PMID- 27698768 TI - Effect of pioglitazone on neuropathic pain and spinal expression of TLR-4 and cytokines. AB - The molecular mechanisms underlying neuropathic pain have yet to be elucidated. The present study aimed to examine the modulation of neuroimmune activation in the spinal cord by the synthetic peroxisome proliferator-activated receptor gamma (PPAR-gamma) agonist, pioglitazone (Pio), in a rat model of neuropathic pain induced by chronic constriction injury (CCI). Rats were randomly assigned into four groups: Sham surgery with vehicle, chronic constriction injury with vehicle or Pio (10 mg/kg), and chronic constriction injury with Pio and a PPAR-gamma antagonist GW9662 (2 mg/kg). Pio or vehicle was administered 1 h prior to the surgery and continued daily until day 7 post-surgery. Paw pressure threshold was measured prior to surgery and on days 0, 1, 3 and 7 post-surgery. Microglia activation markers macrophage antigen complex-1, the mRNA expression levels of tumor necrosis factor alpha and interleukin-1beta, and the mRNA expression levels of toll like receptor (TLR-4) in the lumbar spinal cord were determined. Administration of Pio resulted in the prominent attenuation of mechanical hyperalgesia. In addition, Pio was able to significantly inhibit neuroimmune activation characterized by glial activation, the production of cytokines and expression levels of TLR-4. Concurrent administration of a PPAR-gamma antagonist, GW9662, reversed the effects of Pio. The antihyperalgesic effect of administration of Pio in rats receiving CCI may, in part, be attributed to the inhibition of neuroimmune activation associated with the sustaining of neuropathic pain. PMID- 27698770 TI - Multimodal imaging findings of SAPHO syndrome with no skin lesions: A report of three cases and review of the literature. AB - Synovitis, acne, palmoplantar pustulosis, hyperostosis and osteitis syndrome (SAPHO) is a rare syndrome that affects the skin, bones and joints. Diagnosis of SAPHO syndrome is established on clinical appearance and imaging features. The present case report described the imaging features of three cases of SAPHO with sternoclavicular joint arthritis but without skin manifestations using multiple imaging modalities, including computed tomography (CT), magnetic resonance imaging (MRI) and bone scintigraphy. The first case was a 52-year-old male who suffered from progressive sternoclavicular arthritis for 2 years. The second case was a 62-year-old female with arthritis in the larger joints for 5 years, particularly on the right thoracic area. The third case was a 44-year-old male who exhibited a slight bulge accompanied by pain in the upper anterior chest wall for 4 years. All of them lacked cutaneous lesions. CT demonstrated sclerosis and hyperostosis with subchondral erosions in the sternocostoclavicular joints. MRI revealed bone marrow edema that was slightly hypointense on T1-weighted imaging, and hyperintense on T2-weighted imaging. Typical 'bull head' signs were observed in bone scintigraphy images. The present case study demonstrated that SAPHO syndrome should be suspected in patients with multifocal osteitis or arthritis affecting the chest wall that lack skin manifestations. Multimodal imaging modalities in combination are helpful for SAPHO diagnosis. PMID- 27698771 TI - Identification of the protective effects of traditional medicinal plants against SDS-induced Drosophila gut damage. AB - Traditional medicinal plants are widely used as immunomodulatory medicines that help improve health. A total of 50 different plants used for the treatment of toxicity were screened for their in vivo protective effects. Flies were fed a standard cornmeal-yeast medium (control group) or the standard medium containing medicinal plant extracts (experimental groups). Assessment of the survival rate was performed by feeding flies with toxic compounds. Gut epithelial cells were analyzed for cell proliferation and death by green fluorescent protein antibodies and 7-aminoactinomycin D staining under the microscope. The expression of antimicrobial peptides (AMPs) was evaluated by the quantitative polymerase chain reaction and the results revealed that after feeding the flies with toxic compounds, aqueous extracts from Codonopsis pilosula (Franch.) Nannf (C. pilosula), Saussurea lappa (Decne.) C.B.Clarke (S. lappa), Imperata cylindrica Beauv.var.major (Nees) C.E. Hubb. (I. cylindrical var. major) and Melia toosendan Sied. Et Zucc. (M.toosendan) increased the fly survival rate, reduced epithelial cell death and improved gut morphology. In addition, C. pilosula extracts induced the antimicrobial peptide levels (Dpt and Mtk) following treatment with sodium dodecyl sulfate (SDS). However, these extracts were not observed to increase SDS induced cell proliferation in vivo. These results indicate that there are strong protective effects in extracts of C. pilosula, S. lappa, I. cylindrical var. major and M. toosendan on Drosophila intestinal cells among 50 medicinal plants. PMID- 27698772 TI - Effect of Polygonatum odoratum extract on human breast cancer MDA-MB-231 cell proliferation and apoptosis. AB - Traditional Chinese medicine (TCM) is important in the provision of anti-tumor drugs. Recently, studies have shown that certain types of TCM agents are able to control the growth of tumors, enhance the body's immune function and enhance the therapeutic effect of chemotherapeutic drugs. In women, breast carcinoma is the most common tumor type and the second most common cause of death from cancer. Polygonatum odoratum (P. odoratum) is commonly used in TCM. The aim of the present study was to investigate the effects of P. odoratum extract on the proliferation and apoptosis of MDA-MB-231 breast cancer cells. Cell proliferation was assessed using MTT and colony formation assays. In addition, propidium iodide (PI)/Annexin V-FITC staining was used to investigate the apoptosis of MDA-MB-231 cells following treatment with P. odoratum extract. The protein expression levels of B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax) were also detected using western blot analysis, while a JC-1 staining assay was used to assess the mitochondrial membrane potential (DeltaPsim). The results of the MTT assay showed that the proliferation and colony formation of MDA-MB-231 cells were inhibited following treatment with the extract. Furthermore, the PI/Annexin-V staining showed that the apoptosis of MDA-MB-231 cells was enhanced by the extract, in a concentration-dependent manner. The extract also lowered the DeltaPsim of MDA-MB-231 cells, upregulated the expression of Bax and inhibited the expression of Bcl-2. In conclusion, these results showed that the P. odoratum extract inhibited the proliferation and induced apoptosis of breast cancer MDA-MB 231 cells. PMID- 27698773 TI - Neural stem cell transplantation combined with erythropoietin for the treatment of spinal cord injury in rats. AB - Spinal cord injury (SCI) comprises nerve and motor function disorders that may be caused by a variety of damaging factors and is challenging to treat. The aim of the present study was to investigate the regenerative effects of neural stem cell (NSC) transplantation combined with intraperitoneal injection of erythropoietin (EPO) on cross-sectional SCI in rats. A model of SCI was induced in 40 adult Wistar rats via the complete transection of the 10th thoracic vertebra (T10). The rats were allocated at random into 4 groups: Control, NSC, EPO and NSC + EPO groups (n=10 per group). Morphological alterations associated with axonal regeneration were detected using neurofilament (NF)-200 immunohistochemistry and immunofluorescence staining after 8 weeks. Basso, Beattie and Bresnahan (BBB) scoring was used to evaluate the recovery of hindlimb function. A total of 5 rats died following surgery, including 2 control rats and 1 rat each in the EPO, NSC and NSC + EPO groups. NSCs labeled with bromodeoxyuridine were observed to have survived and migrated in the spinal cord tissue after 8 weeks. Significant histomorphological differences were observed in the NSC and NSC + EPO groups compared with the EPO and control groups. Furthermore, the rats of the NSC + EPO group exhibited significantly enhanced axonal regeneration in the SCI area compared with the NSC group rats. The rats of the NSC and NSC + EPO groups exhibited significantly improved BBB scores compared with the EPO and control group rats at 7 days after treatment (P<0.05). In addition, the BBB scores of the NSC + EPO group were significantly improved compared with those of the three other groups at 7 days after surgery (P<0.05). Therefore, the results of the present study suggest that NSC transplantation combined with intraperitoneal injection of EPO may benefit the survival and regeneration of injured axons, and accelerate the repair of injured spinal cord tissue, thus facilitating the functional recovery of hindlimb locomotor function in rats. PMID- 27698775 TI - Astragaloside IV ameliorates necrotizing enterocolitis by attenuating oxidative stress and suppressing inflammation via the vitamin D3-upregulated protein 1/NF kappaB signaling pathway. AB - Astragaloside IV (AS-IV) is a flavonoid from the plant Astragalus membranaceus (Fisch) Bge that has a wide range of therapeutic effects. The aim of the present study was to examine the effect of AS-IV on rats with necrotizing enterocolitis (NEC) under oxidative stress and inflammation. Newborn Sprague-Dawley rats were induced with NEC by asphyxia and hypothermia applied on 3 consecutive days. The rats were orally administered AS-IV at 25, 50 and 75 mg/kg for 4 days. The results revealed that AS-IV administration prevented NEC-induced decrease in the concentration of malondialdehyde and myeloperoxidase, and increase in the activity of glutathione (GSH) and superoxide dismutase in murine models. AS-IV also inhibited NEC-induced elevation in the levels of interleukin (IL)-6, IL 1beta, tumor necrosis factor-alpha and nuclear factor (NF)-kappaB. The effects of AS-IV were achieved under inflammation and oxidative stress. Western blotting demonstrated that AS-IV substantially inhibited the phosphorylated (p) IkappaBalpha, NF-kappaBp65, p-NF-kappaBp65 protein levels and increased vitamin D3 upregulated protein 1 (VDUP1) and IkappaBalpha protein levels. These data indicate that AS-IV may be effective in the protection of NEC-induced ileum degeneration by inhibiting the levels of inflammatory markers and oxidative stress via the regulation of the VDUP1/NF-kappaB signaling pathway. PMID- 27698774 TI - Long-term health effects of persistent exposure to low-dose lr192 gamma-rays. AB - The aim of the present study was to investigate the effect of persistent low-dose iridium-192 (Ir192) exposure on immunological function, chromosome aberration and the telomerase activity of bone marrow mononuclear cells (BMNCs), in order to increase clinical knowledge of the late effects of persistent low-dose Ir192 gamma-ray exposure. Patients (n=54) accidentally exposed to persistent low-dose Ir192 were included in this 10-year follow-up study. Clinical symptoms, peripheral blood, bone marrow, cellular and humoral immune status, chromosome aberrations and the telomerase activity of BMNCs were analyzed in this study. Exposure to low-dose Ir192 resulted in different degrees of clinical symptoms and significantly lowered complement C3 and C4 levels, CD3+, CD4+ and CD8+ T cell levels, the lymphocyte transformation rate and the percentage of natural killer (NK) cells. It also led to increases in peripheral blood and bone marrow abnormality rates, chromosome aberration rate and BMNC telomerase activity. Exposure to persistent low-dose Ir192 radiation resulted in different degrees of immune dysfunction, and abnormalities of blood cells and bone marrow, which recovered within 1-3 years. Chromosome aberrations were observed to take 5-10 years to recover. However, it would take >10 years for the telomerase activity of BMNCs to be reduced to normal levels. A prolonged follow-up time is required in order to monitor clonal proliferative diseases such as leukemia. PMID- 27698776 TI - Anticancer effect of cucurbitacin B on MKN-45 cells via inhibition of the JAK2/STAT3 signaling pathway. AB - The aim of the present study was to investigate the effect of cucurbitacin B on MKN-45 gastric carcinoma cells. Cell proliferation was determined using a cell counting kit-8 assay, and commercial cell cycle and apoptosis analysis kits were used to determine the cell cycle by flow cytometry. The mRNA expression of genes which mediate cell cycle checkpoints and apoptosis was detected using reverse transcription-quantitative polymerase chain reaction, and a terminal deoxynucleotidyl transferase dUTP nick end labeling assay was used to determine apoptosis rate. Western blot analysis was used to detect the protein expression levels of JAK2/STAT3 signaling pathway-associated proteins. The presented data show that cucurbitacin B significantly inhibited the proliferation of MKN-45 cells in a dose- and time-dependent manner. In accordance with these findings, cucurbitacin B blocked the progression of the cell cycle from G0/G1 to S phase, which was confirmed by the mRNA expression analysis. Cucurbitacin B treatment significantly suppressed the expression of cyclin D1, cyclin E, cyclin-dependent kinase 4 (CDK4) and CDK2, while increasing the expression of p27. Cucurbitacin B also promoted cell apoptosis, as was determined by TUNEL assay and evaluation of mRNA expression. Further experiments suggested that the beneficial effect of cucurbitacin B on blocking the proliferation and inducing the apoptosis of MKN-45 cells may have been associated with suppression of the JAK2/STAT3 signaling pathway. Thus, the present results indicate that cucurbitacin B suppresses proliferation and promoted apoptosis of MKN-45 cells, which may be mediated by inhibition of the JAK2/STAT3 signaling pathway. Cucurbitacin B therefore may warrant further investigation as a feasible therapy for gastric carcinoma. PMID- 27698777 TI - Expression and regulation of the ery operon of Brucella melitensis in human trophoblast cells. AB - Brucellosis is primarily a disease of domestic animals in which the bacteria localizes to fetal tissues such as embryonic trophoblast cells and fluids containing erythritol, which stimulates Brucella spp. growth. The utilization of erythritol is a characteristic of the genus Brucella. The ery operon contains four genes (eryA, eryB, eryC and eryD) for the utilization of erythritol, and plays a major role in the survival and multiplication of Brucella spp. The objective of the present study was to conduct a preliminary characterization of differential genes expression of the ery operon at several time points after Brucella infected embryonic trophoblast cells (HPT-8 cells). The result showed that the ery operon expression was higher in HPT-8 cells compared with the medium. The relative expression of eryA, eryB and eryC peaked at 2 h post infection in HPT-8 cells, and eryD expression peaked at 3 h post-infection. The expression of eryA, eryB and eryC may be inhibited by increased eryD expression. However, the expression of the ery operon was stable in the presence of erythritol in cells. 2308Deltaery and 027Deltaery mutants of the ery operon were successfully constructed by homologous recombination, which were attenuated in RAW 264.7 murine macrophages. The characterization of the ery operon genes and their expression profiles in response to Brucella infection further contributes to our understanding of the molecular mechanisms of infection and the pathogenesis of brucellosis. PMID- 27698778 TI - Scrub typhus associated with hemophagocytic lymphohistiocytosis: A report of six pediatric patients. AB - Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening immune disorder that may be inherited or secondary to infection, malignancy or rheumatological disease. The aim of the present study was to highlight the clinical features of scrub typhus-associated HLH in children. A retrospective study was performed on 6 pediatric patients with scrub typhus-associated HLH. For each patient, medical records were reviewed and analyzed, and demographic, clinical and laboratory data and outcomes were collected. The duration of fever prior to admission ranged between 4 and 12 days. All patients exhibited persistent or intermittent fever, eschar, hepatosplenomegaly and lymphadenopathy at the time of diagnosis. Five patients experienced acute respiratory distress syndrome and disseminated intravascular coagulation (DIC) during hospitalization. Thrombocytopenia was detected in all patients with cytopenia involving two or three cell types, simultaneously. Coagulopathy with prolonged prothrombin time and/or activated partial thromboplastin time were noted in all patients. Markedly elevated serum ferritin levels (>1,500 ug/ml) were identified in all patients. Elevated lactate dehydrogenase (>1,000 U/l) was detected in 4 (66.7%) patients and elevated alanine aminotransferase was exhibited by 5 (83/3%) patients. Lung infiltrates and consolidation were the most common imaging findings. Only 1 patient succumbed, with DIC and multi-organ failure. Of the survivors, 1 patient was lost to follow-up, and the remaining patients are in remission with excellent general health, to date. In conclusion, HLH should be considered in severe pediatric cases of scrub typhus. Upon the early recognition of this syndrome, prompt and supportive treatment in the pediatric intensive care unit are vital. PMID- 27698779 TI - Tanshinone IIA pretreatment attenuates ischemia/reperfusion-induced renal injury. AB - Tanshinone IIA is a chemical compound extracted from the root of traditional Chinese herb Salvia miltiorrhiza Bunge. Tanshinone IIA has been suggested to possess anti-inflammatory activity and antioxidizing capability. Recently, accumulating results have indicated the antitumor activity of tanshinone IIA; thus, it has attracted increasing attention. In addition, tanshinone IIA has been indicated to attenuate ischemia/reperfusion induced renal injury (I/RIRI); however, little is known regarding the underlying mechanisms involved in this process. In the present study an I/RIRI rat model was used to analyze the effects of tanshinone IIA on myeloperoxidase (MPO), TNF-alpha and IL-6 activities using ELISA kits. Furthermore, macrophage migration inhibitory factor (MIF), cleaved caspase-3, B-cell lymphoma 2 (Bcl-2) and p38 mitogen-activated protein kinase (MAPK) protein expression levels were evaluated using western blot analysis. The results indicated that tanshinone IIA protected renal function in I/RIRI rats. ELISA demonstrated that tanshinone IIA significantly reduced MIF, TNF-alpha and IL-6 activities in I/RIRI rats. Western blot analysis showed that tanshinone IIA significantly suppressed MIF, cleaved caspase-3 and p38 MAPK protein expression levels in I/RIRI rats. The present results suggest that tanshinone IIA pretreatment attenuates I/RIRI via the downregulation of MPO expression, inflammation, MIF, cleaved caspase-3 and p38 MAPK. PMID- 27698780 TI - miR-448 downregulates MPPED2 to promote cancer proliferation and inhibit apoptosis in oral squamous cell carcinoma. AB - The incidence of oral squamous cell carcinoma (OSCC) is continuously increasing while its survival rate has not notably improved. There is a pressing need for improved understanding of the genetic regulation of OSCC tumorigenesis and progression. In this study, the function of miR-448 in the regulation of OSCC growth and its putative target were thoroughly analyzed in vitro. The expression of miR-448 was detected in human OSCC specimens and OSCC cell lines (Cal-27 and Scc-9) by reverse transcription-quantitative polymerase chain reaction. The function of miR-448 was investigated in Cal-27 cells transfected with miR-448 inhibitor, and its putative target determined using a luciferase reporter assay. MTT and wound healing assays and flow cytometry were used to evaluate the effects of miR-448 on OSCC proliferation, metastasis and apoptosis. The level of miR-448 was significantly elevated in human OSCC tissues and the Cal-27 cell line. Suppression of miR-448 expression attenuated cell proliferation and migration, and induced apoptosis of Cal-27 cells. Furthermore, miR-448 bound with the 3' untranslated region of metallophosphoesterase domain containing 2 (MPPED2) mRNA, thereby reducing the MPPED2 protein level. Thus, it appears that miR-448 acts as a tumor inducer, causing OSCC growth by inhibiting the expression of its target MPPED2. These results demonstrate that miR-448 plays a critical role in OSCC tumorigenesis, and is a potential therapeutic target. PMID- 27698781 TI - Expression and location of HSP60 and HSP10 in the heart tissue of heat-stressed rats. AB - The present study aimed to analyze the expression levels and localizations of heat shock protein (HSP) 60 and HSP10 in the heart tissue of rats subjected to heat stress (42 degrees C) for 0, 20, 80 and 100 min. Histopathological injuries and increased serum activities of serum lactate dehydrogenase and creatine kinase isoenzyme MB were detected in the heated rat myocardial cells. These results suggested that heat stress-induced acute degeneration may be sufficient to cause sudden death in animals by disrupting the function and permeability of the myocardial cell membrane. In addition, the expression levels of HSP60 were significantly increased following 20 min heat stress, whereas the expression levels of its cofactor HSP10 were not. Furthermore, the location of HSP60, but not of HSP10, was significantly altered during periods of heat stress. These results suggested that HSP60 in myocardial tissue may be more susceptive to the effects of heat stress as compared with HSP10, and that HSP10 is constitutively expressed in the heart of rats. The expression levels and localizations of HSP60 and HSP10 at the different time points of heat stress were not similar, which suggested that HSP60 and HSP10 may not form a complex in the heart tissue of heat stressed rats. PMID- 27698782 TI - Clinicopathological characteristics of thyroid cancer misdiagnosed by fine needle aspiration. AB - Fine-needle aspiration (FNA) is commonly used as a preoperative assessment to diagnose thyroid cancer. However, misdiagnosis of malignancy by FNA is not rare, even if image examination suggests the possibility of thyroid cancer. In the present study, the clinicopathological factors of patients whose preoperative FNA examination had not led to a diagnosis of thyroid cancer were examined. In total, 125 patients with thyroid cancer who underwent FNA and surgery (total thyroidectomy, subtotal thyroidectomy or hemithyroidectomy) at the Department of Surgery, Surgical Oncology and Science of the Sapporo Medical University Hospital between 2006 and 2013 were retrospectively analyzed. The patients were divided into two groups: Group A, malignancy determined by FNA, and group B, no malignancy. The groups were then compared by gender, age, tumor size, stage, tumor stage, lymph node metastasis, histology, surgical procedure methods, presence or absence of calcification and thyroglobulin levels. The mean age of the patients in group A (5 males and 59 females) was 53.0 years. The mean age in group B (11 males and 49 females) was 54.2 years. The mean tumor size in both groups was 1.6 cm. The mean thyroglobulin levels were 82.7 ng/ml in Group A and 525.5 ng/ml in group B. There were also significant differences between the groups for tumor stage (P=0.046), histological type (P=0.024) and thyroglobulin levels (P=0.035). The results of the present study suggested that it may be difficult to diagnose thyroid cancer by FNA in cases with non-papillary carcinoma and higher thyroglobulin levels. PMID- 27698783 TI - Increased receptor activator of nuclear factor kappabeta ligand/osteoprotegerin ratio exacerbates cartilage destruction in osteoarthritis in vitro. AB - Osteoarthritis (OA) is a degenerative joint disease characterized by progressive cartilage destruction, matrix degradation and bony changes. Subchondral bone alterations in osteoarthritis are associated with cartilage destruction. It has previously been demonstrated that osteoprotegerin (OPG) and receptor activator of nuclear factor kappabeta ligand (RANKL) mediate this process. The RANKL/OPG ratio is altered in OA chondrocytes compared with normal chondrocytes. In the pathogenesis of OA, abnormal expression levels of matrix metalloproteinase-13 (MMP-13) are secreted by chondrocytes has a vital role in the progression of cartilage erosion. In the present study, the effect of various RANKL/OPG ratios on MMP-13 expression levels was investigated in interleukin-1beta-stimulated SW1353 human chondrosarcoma cells. Cell viability was assessed by MTT assay and MMP-13 mRNA and protein expression levels were analyzed by quantitative reverse transcription-quantitative polymerase chain reaction, ELISA and western blot analyses, respectively. The results demonstrated that an increase in MMP-13 mRNA and protein expression levels was observed with increasing RANKL/OPG ratio. These findings suggest that this mechanism may be used as a novel therapeutic strategy against OA. PMID- 27698784 TI - OMP31 of Brucella melitensis 16M impairs the apoptosis of macrophages triggered by TNF-alpha. AB - Outer membrane proteins (OMPs) of microorganisms play important roles in directly interacting with host cells. Brucella species inhibit the apoptosis of host cells to benefit their own intracellular survival and replication. However, the association between OMP31 of Brucella and host cell apoptosis, and the underlying mechanism are unclear. In this study, an OMP31 gene deletion mutant based on B. melitensis 16M was constructed. Following the infection of RAW264.7 cells with B. melitensis 16M or the mutant strain, colony formation, apoptosis, tumor necrosis factor (TNF)-alpha levels and the levels of key downstream factors of the apoptosis pathways triggered by TNF-alpha, namely caspase-3, -8 and -9, cytochrome c, B-cell lymphoma 2 (Bcl-2) and Bcl-2-associated X protein (Bax) were detected. The mutant strain was shown to have the same phenotype as the parent strain using traditional microbiological tests. However, the mutant strain had impaired intracellular survival, with higher levels of apoptosis and TNF-alpha expression in infected RAW164.7 macrophages than the parent strain. The downstream factors of apoptosis triggered by TNF-alpha, including increased caspase-8, -3 and -9, cytochrome c and Bax, and decreased Bcl-2, indicated that the classical and mitochondrial cell death pathways were involved. It may be concluded that OMP31 from Brucella inhibited apoptosis and benefitted the intracellular survival of this microorganism. Furthermore, TNF-alpha may have served as a switch triggering classical death and mitochondrial cell death pathways. PMID- 27698785 TI - Anti-inflammatory activity of liposomes of Asparagus racemosus root extracts prepared by various methods. AB - Asparagus racemosus root extracts (AR) have been reported to possess a variety of pharmacological properties. The aim of the present study was to develop liposomes of AR and to assess their physicochemical characteristics and anti-inflammatory activity in the monocytic leukemia cell line THP-1. Liposomes containing various ratios of AR to lipid and a phosphatidylcholine to cholesterol molar ratio of 7:3 were prepared by thin-film hydration (TF), reverse-phase evaporation (REV) and polyol dilution (PD). The results showed that AR liposomes prepared by TF had a multilamellar structure and a large size, whereas those prepared by REV and PD were oligolamellar in structure, and of a smaller size. The particle sizes and zeta potentials of the liposomes ranged from 196.5 to 456.6 nm and from -4.34 to 18.94 mV, respectively. The AR to lipid ratio was shown to have no significant influence on particle size, while the zeta potential generally increased with increasing AR to lipid ratio. The highest entrapment efficiency values were detected in liposomes with an AR to lipid ratio of 1:5, and for liposomes prepared by TF, REV and PD methods, the entrapment efficiencies were 55.71+/ 2.04, 56.21+/-3.59 and 67.68+/-1.37%, respectively. AR was found to exert no toxicity on THP-1 cells. The maximum anti-inflammatory activities of AR and AR liposomes, evaluated in terms of the percentage inhibition of tumor necrosis factor-alpha in THP-1 cells, were ~52% at a concentration of 1 ug/ml. It can be concluded from the present study that AR liposomes have the potential to be used a formulation for topical and/or transdermal drug delivery to provide anti inflammatory activity. PMID- 27698786 TI - Involvement of macrophage migration inhibitory factor in cancer and novel therapeutic targets. AB - Macrophage migration inhibitory factor (MIF) was originally identified in 1966 by Bloom and Bennett as a pro-inflammatory cytokine involved in the inhibition of macrophage motility. Since then, studies have investigated the functional contribution of this pro-inflammatory cytokine in several immune diseases, including rheumatoid arthritis and lupus erythematous. Recently, MIF has been reported to be involved in a variety of neoplastic diseases. The present review discusses previous cancer research studies that have investigated the involvement of MIF in carcinogenesis, disease prognosis, tumor cell proliferation and invasion, and tumor-induced angiogenesis. Finally, potential therapeutic approaches based on the use of MIF antagonists and neutralizing antibodies are examined. The review concludes that MIF could be a good prognostic biomarker in several types of cancer, but also that the inhibition of MIF could represent a novel therapy against cancer. PMID- 27698788 TI - Why man's best friend, the dog, could also benefit from an anti-HER-2 vaccine. AB - Human epidermal growth factor receptor-2 (HER-2) is a well-established target for anticancer anticancerprecision medicine in humans. A HER-2 homologue with 92% amino acid identity has been described in canine mammary tumors, which whichis termed here as 'dog epidermal growth factor receptor-2 (DER-2)', with similar biological implications as those in human breast cancer. Both antigens can principally be immunologically targeted by anti-HER-2 antibodies, such as trastuzumab; however, the in vivo application applicationof humanized antibodies to other species would lead to specific hypersensitivity reactions. Therefore, HER-2 mimotope vaccines that actively induce autologous trastuzumab-like immunoglobulins represent a novel and economic treatment option to overcome species-specific limitations. Thus, the present review proposes the implementation of clinical trials with HER-2 vaccines in canine cancer model modelpatients with spontaneous DER-2 positive mammary gland carcinomas in order to assess their safety and efficacy. This approach would not only pave the way into the veterinary oncology market, but would also similarly generate robust data for human trials and facilitate the testing of novel combinatorial treatments. PMID- 27698787 TI - Cancer stem cells as a potential therapeutic target in thyroid carcinoma. AB - A number of studies have indicated that tumor growth and proliferation is dependent on a small subset of cells, defined as cancer stem cells (CSCs). CSCs have the capability to self-renew, and are involved with cancer propagation, relapse and metastatic dissemination. CSCs have been isolated from numerous tissues, including normal and cancerous thyroid tissue. A regulatory network of signaling pathways and microRNAs (miRNAs) control the properties of CSCs. Differentiated thyroid carcinoma is the most common type of endocrine cancer, with an increasing incidence. Anaplastic thyroid carcinoma is the most rare type of endocrine cancer; however, it also exhibits the highest mortality rate among thyroid malignancies, with an extremely short survival time. Thyroid CSCs are invasive and highly resistant to conventional therapies, including radiotherapy and chemotherapy, which results in disease relapse even when the primary lesion has been eradicated. Therefore, targeting thyroid CSCs may represent an effective treatment strategy against aggressive neoplasms, including recurrent and radioresistant tumors. The present review summarizes the current literature regarding thyroid CSCs and discusses therapeutic strategies that target these cells, with a focus on the function of self-renewal pathways and miRNAs. Elucidation of the mechanisms that regulate CSC growth and survival may improve novel therapeutic approaches for treatment-resistant thyroid cancers. PMID- 27698789 TI - Role of Yes-associated protein in cancer: An update. AB - Yes-associated protein (YAP) is an oncoprotein located in the cytoplasm in an inactive form, and when activated, it translocates to the nucleus and activates the transcription of genes responsible for cell division and apoptosis. YAP is one of the downstream regulatory proteins in the Hippo signaling pathway, which is important in cell proliferation and regeneration. Due to its great importance, YAP is regulated very strictly by different regulatory systems. The present review will focus on the canonical pathways of YAP, and will provide details on the most recent findings regarding its regulation and role in tumorigenesis, specifically in prostate tumor progression. PMID- 27698790 TI - Glioblastoma multiforme: Effect of hypoxia and hypoxia inducible factors on therapeutic approaches. AB - Central nervous system-based cancers have a much higher mortality rate with the 2016 estimates at 6.4 for incidence and 4.3 for deaths per 100,000 individuals. Grade IV astrocytomas, known as glioblastomas are highly aggressive and show a high proliferation index, diffused infiltration, angiogenesis, microvascular proliferation and pleomorphic vessels, resistance to apoptosis, and pseudopalisading necrosis. Extensive hypoxic regions in glioblastomas contribute to the highly malignant phenotype of these tumors. Hypoxic regions of glioblastoma exacerbate the prognosis and clinical outcomes of the patients as hypoxic tumor cells are resistant to chemo- and radiation therapy and are also protected by the malfunctional vasculature that developed due to hypoxia. Predominantly, hypoxia-inducible factor-1alpha, vascular endothelial growth factor (VEGF)/VEGF receptor, transforming growth factor-beta, epidermal growth factor receptor and PI3 kinase/Akt signaling systems are involved in tumor progression and growth. Glioblastomas are predominantly glycolytic and hypoxia induced factors are useful in the metabolic reprogramming of these tumors. Abnormal vessel formation is crucial in generating pseudopalisading necrosis regions that protect cancer stem cells residing in that region from therapeutic agents and this facilitates the cancer stem cell niche to expand and contribute to cell proliferation and tumor growth. Therapeutic approaches that target hypoxia-induced factors, such as use of the monoclonal antibody against VEGF, bevacizumab, have been useful only in stabilizing the disease but failed to increase overall survival. Hypoxia-activated TH-302, a nitroimidazole prodrug of cytotoxin bromo-isophosphoramide mustard, appears to be more attractive due to its better beneficial effects in glioblastoma patients. A better understanding of the hypoxia-mediated protection of glioblastoma cells is required for developing more effective therapeutics. PMID- 27698791 TI - MicroRNAs and PIWI-interacting RNAs in oncology. AB - RNA molecules that are unable to translate into proteins are classified as non coding RNA. Non-coding RNA (ncRNA) genes include highly abundant and functionally important RNAs such as transfer RNAs, microRNAs (miRNAs), siRNAs, snRNAs, exRNAs and piRNAs. The number of ncRNAs encoded within the human genome is unknown; however, recent transcriptomic and bioinformatic studies suggest the existence of thousands of ncRNAs. Furthermore, small ncRNAs, including miRNAs and PIWI interacting RNAs (piRNAs), play an imperative role in the regulation of gene expression of numerous biological and pathological processes. Investigation into the expression and function of small RNA in cancer cells has contributed to gaining a greater understanding of the roles of small RNAs in carcinogenesis. The present review is aimed primarily to discuss the importance of the expression and functions of these small RNAs in carcinogenesis. These studies may provide useful information for future therapies in cancer. PMID- 27698792 TI - Expression of microRNA-181 determines response to treatment with azacitidine and predicts survival in elderly patients with acute myeloid leukaemia. AB - MicroRNAs (miRs) are small non-coding RNAs that play important roles in cell differentiation and survival. Abnormal expression of miRs has been demonstrated in numerous types of cancer, including acute myeloid leukaemia (AML). The aim of the present study was to evaluate miR-181 expression at diagnosis and following the completion of chemotherapy in AML patients, with regard to clinical response and outcome, particularly in patients treated with azacitidine. miR-181 expression was analysed using reverse transcription-quantitative polymerase chain reaction in 95 bone marrow specimens from newly diagnosed AML patients and in 20 healthy subjects for comparison. The results revealed upregulated miR-181 expression in the total cohort of AML patients, which was correlated with longer survival. However, in a subset of older AML patients treated with azacitidine, low miR-181 expression at diagnosis was a predictor for complete remission and prolonged survival. The findings indicated that miR-181 has an important role in AML and determines response to azacitidine treatment in older AML patients. PMID- 27698793 TI - miR-186 suppressed CYLD expression and promoted cell proliferation in human melanoma. AB - Previous studies have shown that microRNA-186 (miR-186) is overexpressed in various human cancers and is associated with the regulation of the carcinogenic processes. However, the underlying mechanisms of this microRNA in melanoma remain largely unknown. In the present study, the overexpression of miR-186 was identified in melanoma tissues and melanoma cells compared to the expression of miR-186 in the matched tumor adjacent tissues and normal human epidermal melanocytes. Overexpression of miR-186 promoted the proliferation and anchorage independent growth of melanoma cells, whereas inhibition of miR-186 reduced this effect. Bioinformatics analysis also revealed cylindromatosis (CYLD), a putative tumor suppressor, to be a potential target of miR-186. Luciferase reporter assays showed that miR-186 directly targeted the 3'-untranslated regions of CYLD messenger RNA. Additional experiments showed that overexpression of miR-186 promoted the proliferation of melanoma cells, which was consistent with the inhibitory effects induced by knockdown of CYLD. In summary, the present study indicated that miRNA-186 plays a crucial role in melanoma growth and its oncogenic effect is mediated chiefly through the direct suppression of CYLD expression. PMID- 27698794 TI - Two novel susceptibility loci for non-small cell lung cancer map to low-density lipoprotein receptor-related protein 5. AB - This study investigated the effect of single-nucleotide polymorphisms (SNPs) of low-density lipoprotein receptor-related protein 5 (LRP5) on the risk of developing non-small cell lung cancer (NSCLC). A total of 500 NSCLC patients and 500 healthy controls were recruited for genotyping of 11 SNPs of LRP5. The association between genotype and NSCLC risk was evaluated by computing the odds ratio (OR) and 95% confidence interval (CI) from multivariate unconditional logistic regression analyses. Eleven Tag SNPs were detected. The frequency of the LRP5 rs3736228 T allele (18.9% in male NSCLC cases and 23.9% in male controls) was statistically different between male NSCLCs and male controls (P=0.03), and the T allele was associated with a lower risk of NSCLC (OR=0.74; 95% CI, 0.56 0.67), whereas the C/C homozygous genotype and the LRP5 rs64843 T/T genotype were associated with an increased risk of NSCLC and squamous cell carcinoma (SCC), respectively (OR=1.43 and 1.77, respectively). Using Haploview software, the frequency of the haplotypes of rs312009/rs3120015/rs3120014 CCC was was significantly higher in female SCC cases compared with female controls (0.064 vs. 0.009, P=0.04). LRP5 rs3736228 and rs64843 SNPs were significantly associated with an increased risk of NSCLC and SCC, respectively. Further studies are required to investigate the functional changes in LRP5 expression and activity in NSCLC in vitro. PMID- 27698795 TI - Whole-exome sequencing identifies variants in invasive pituitary adenomas. AB - Pituitary adenomas exhibit a wide range of behaviors. The prediction of invasion or malignant behavior in pituitary adenomas remains challenging. The objective of the present study was to identify the genetic abnormalities associated with invasion in sporadic pituitary adenomas. In the present study, the exomes of six invasive pituitary adenomas (IPA) and six non-invasive pituitary adenomas (nIPA) were sequenced by whole-exome sequencing. Variants were confirmed by dideoxynucleotide sequencing, and candidate driver genes were assessed in an additional 28 pituitary adenomas. A total of 15 identified variants were mainly associated with angiogenesis, metabolism, cell cycle phase, cellular component organization, cytoskeleton and biogenesis immune at a cellular level, including 13 variants that occurred as single nucleotide variants and 2 that comprised of insertions. The messenger RNA (mRNA) levels of diffuse panbronchiolitis critical region 1 (DPCR1), KIAA0226, myxovirus (influenza virus) resistance, proline-rich protein BstNI subfamily 3, PR domain containing 2, with ZNF domain, RIZ1 (PRDM2), PR domain containing 8 (PRDM8), SPANX family member N2 (SPANXN2), TRIO and F actin binding protein and zinc finger protein 717 in IPA specimens were 50% decreased compared with nIPA specimens. In particular, DPCR1, PRDM2, PRDM8 and SPANXN2 mRNA levels in IPA specimens were approximately four-fold lower compared with nIPA specimens (P=0.003, 0.007, 0.009 and 0.004, respectively). By contrast, the mRNA levels of dentin sialophospho protein, EGF like domain, multiple 7 (EGFL7), low density lipoprotein receptor-related protein 1B and dynein, axonemal, assembly factor 1 (LRRC50) were increased in IPA compared with nIPA specimens (P=0.041, 0.037, 0.022 and 0.013, respectively). Furthermore, decreased PRDM2 expression was associated with tumor recurrence. The findings of the present study indicate that DPCR1, EGFL7, the PRDM family and LRRC50 in pituitary adenomas are modifiers of tumorigenesis, and most likely contribute to the development of oncocytic change and to the invasive tumor phenotype. PMID- 27698796 TI - Mechanism analysis of colorectal cancer according to the microRNA expression profile. AB - The present study aimed to identify specific microRNAs (miRs) and their predicted target genes to clarify the molecular mechanisms of colorectal cancer (CRC). An miR expression profile (array ID, GSE39833), which consisted of 88 CRC samples with various tumor-necrosis-metastasis stages and 11 healthy controls, was downloaded from the Gene Expression Omnibus database. Subsequently, the differentially expressed miRs and their target genes were screened. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathways of target genes were analyzed using the Database for Annotation Visualization and Integrated Discovery. A protein-protein interaction (PPI) network of the target genes was constructed using the Search Tool for the Retrieval of Interacting Genes database. The present study identified a total of 18 differentially expressed miRs (upregulated, 8; downregulated, 10) in the sera of the CRC patients compared with the healthy controls. Of these, 3 upregulated (let-7b, miR-1290 and miR-126) and 2 downregulated (miR-16 and miR-760) differentially expressed miRs and their target genes, including cyclin D1 (CCND1), v-myc avian myelocytomatosis viral oncogene homolog (MYC), phosphoinositide-3-kinase, regulatory subunit 2 (beta) (PIK3R2) and SMAD family member 3 (SMAD3), were significantly enriched in the CRC developmental pathway. All these target genes had higher node degrees in the PPI network. In conclusion, let-7b, miR-1290, miR-126, miR-16 and miR-760 and their target genes, CCND1, MYC, PIK3R2 and SMAD3, may be important in the molecular mechanisms for the progression of CRC. PMID- 27698797 TI - Antitumor effects of the hyaluronan inhibitor 4-methylumbelliferone on pancreatic cancer. AB - Hyaluronan (HA) is a major component of the extracellular matrix (ECM), and influences tumor invasion and metastasis. In a previous study, the present authors reported for the first time that 4-methylumbelliferone (MU) inhibited HA synthesis and suppressed tumor growth. However, the localization of HA and the changes in ECM morphology caused by MU in pancreatic cancer remain to be examined in detail. In the present study, the cytotoxicity of MU and its effect on cellular proliferation was evaluated in the human pancreatic cancer cell line MIA PaCa-2. The amount of HA synthesized and the retention of HA around the cells were quantitatively and immunohistochemically analyzed in vitro and in vivo. Structural changes in the ECM in the tumor tissue were investigated using an electron microscope. MU treatment led to a decrease in extracellular HA retention, as evidenced by a particle exclusion assay and immunohistochemical staining. Cell proliferation was suppressed by MU in a dose-dependent manner. The release of lactate dehydrogenase into the culture medium due to damage to the cellular membrane did not increase following MU administration. In tumor inoculated mice, MU suppressed any increase in tumor volume and decreased the quantity of HA. Electron microscopy revealed that MU attenuated the intercellular space and caused it to be less cohesive. These data indicate that MU inhibits HA synthesis and reduces the amount of HA in the ECM while exhibiting no obvious cytotoxic effect. These findings suggest that MU has potential as a novel therapeutic agent for pancreatic cancer. PMID- 27698799 TI - Expression of cyclooxygenase-2 in cervical cancer is associated with lymphovascular invasion. AB - Cyclooxygenase-2 (COX-2) is associated with carcinogenesis and tumor progression. The current study analyzed the effect of COX-2 expression in patients with invasive squamous cervical cancer. Tissue samples from 123 cervical cancer patients were collected for a retrospective analysis using immunohistochemistry (IHC) with an antibody against COX-2. The clinical and survival data of the patients were analyzed. Positive staining for COX-2 (defined as an immunoreactivity score of >=4) was detected in 28 patients (23%), with significantly higher percentages of staining in tumor cells compared with peritumoral stroma cells (P<0.001). COX-2 expression was significantly associated with lymphovascular space invasion (LVSI; P=0.017). The association of COX-2 expression with LVSI suggests a possible effect of COX-2 on tumor progression in cervical cancer. Further studies including larger patient collectives are required in order to perform analyses of clinical subgroups and patient survival. PMID- 27698798 TI - Celecoxib exhibits an anti-gastric cancer effect by targeting focal adhesion and leukocyte transendothelial migration-associated genes. AB - Gastric cancer (GC) is a prevalent cancer, which remains incurable, and therefore requires an alternative treatment method. Celecoxib is a nonsteroidal anti inflammatory drug that targets cyclooxygenase-2, and exhibits anticancer effects. The present study aimed to investigate the anti-GC mechanism of celecoxib using bioinformatics methods. Gene expression datasets GSE56807 (GC tissues and normal gastric tissues) and GSE54657 (celecoxib-treated and non-treated human GC epithelial AGS cells) were downloaded from the Gene Expression Omnibus database. Two groups of differentially expressed genes (DEGs) were identified using limma package in R language. The criterion for GSE56807 was a false discovery rate of <0.05, while that for GSE54657 was P<0.01. Overlapping DEGs from the two datasets were screened out. Subsequently, pathway enrichment analysis was performed using Database for Annotation, Visualization and Integrated Discovery software (P<0.1; gene count >=2). In addition, the protein-protein interactions (PPIs) among the overlapped DEGs were obtained based on IntAct, Database of Interacting Proteins, Biomolecular Interaction Network Database and Human Protein Reference Database. Finally, a PPI network was visualized using Cytoscape software. A total of 137 overlapped DEGs were obtained, and DEGs with opposite regulation directions in the two datasets were significantly enriched in focal adhesion and leukocyte transendothelial migration. Subsequently, a PPI network of overlapped DEGs was constructed. Comprehensively, a total of 8 key DEGs [cysteine and glycine rich protein 1 (CSRP1), thrombospondin 1 (THBS1), myosin light chain 9 (MYL9), filamin A (FLNA), actinin alpha 1 (ACTN1), vinculin (VCL), laminin subunit gamma 2 (LAMC2) and claudin 1 (CLDN1)] were upregulated in GC tissues and downregulated in celecoxib-treated cells. In conclusion, celecoxib may exhibit anti-GC effects by suppressing the expression of CSRP1, THBS1, MYL9, FLNA, ACTN1, VCL, LAMC2 and CLDN1, and inhibiting leukocyte transendothelial migration and focal adhesion. However, relevant experiments are required to confirm the conclusion of the present study. PMID- 27698800 TI - High expression of lncRNA PVT1 promotes invasion by inducing epithelial-to mesenchymal transition in esophageal cancer. AB - The long non-coding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) has been identified as an oncogene in numerous diseases, and aberrant lncRNA PVT1 expression has been associated with the development of cancer. However, the underlying mechanism by which lncRNA PVT1 affects cell invasion in esophageal cancer has been not demonstrated. In the current study, the expression of lncRNA PVT1 was found to be increased in esophageal cancer specimens (n=77) by reverse transcription-quantitative polymerase chain reaction, and was correlated with tumor stage (P=0.009) and metastasis (P<0.001). In vitro, by using transwell assay, upregulation of lncRNA PVT1 promoted the invasion of TE-1 esophageal cancer cells; while downregulation of lncRNA PVT1 inhibited Eca-109 cell invasion. In addition, western blot analysis indicated that upregulation of lncRNA PVT1 may induce epithelial-to-mesenchymal transition (EMT) by regulating the expression levels of EMT markers (E-cadherin, N-cadherin and vimentin). In conclusion, lncRNA PVT1 is able to regulate the invasion of esophageal cancer cells by inducing EMT. PMID- 27698801 TI - Combined use of free light chain and heavy/light chain ratios allow diagnosis and monitoring of patients with monoclonal gammopathies: Experience of a single institute, with three exemplar case reports. AB - Monoclonal gammopathies are characterized by serum monoclonal component (MC) plus an intact immunoglobulin and a free light chain (FLC), or a combination of both. The measurement of FLC with Freelite(r) is the standard practice recommended by International Myeloma Working Group guidelines. Recently, Hevylite(r) heavy/light chains (HLC) assays were introduced to specifically target junctional epitopes between the heavy and light chains of intact immunoglobulins, allowing the independent quantification of the involved (MC) and uninvolved (polyclonal immunoglobulin background) HLC isotype. Between January 2012 and March 2014, 90 patients were examined: 49 multiple myeloma (MM), 6 smoldering MM (SMM) and 35 monoclonal gammopathy of undetermined significance (MGUS). Of these 90 patients, 300 samples were collected at different times. The diagnostic and monitoring contribution of Hevylite A and G assays was assessed in all 90 patients examined. Additionally, 3 representative cases were selected. The Hevylite absolute values and ratio demonstrated high sensitivity and specificity with respect to serum protein electrophoresis and serum immunofixation. The combined use of Hevylite A and G with Freelite was particularly useful in dubious cases with more than one MC or with co-migrating components, as well as in the course of monitoring to assess the independent change of FLC and HLC, possibly reflecting the presence of clonal heterogeneity in the cohort. From this study, it can be concluded that FLC and HLC are independent, useful markers to monitor the MC and to assess with greater specificity and sensitivity the effect of therapy, thereby providing clinical support. Further studies are required to assess the prognostic potential of Hevylite in MGUS and SMM. PMID- 27698802 TI - Identification of genes involved in Epstein-Barr virus-associated nasopharyngeal carcinoma. AB - Nasopharyngeal carcinoma (NPC) is the most common cancer originating from the nasopharynx, and can be induced by infection with Epstein-Barr virus (EBV). To study the mechanisms of EBV-associated NPC, a microarray of the GSE12452 dataset was analyzed. GSE12452 was downloaded from Gene Expression Omnibus and consisted of 31 NPC samples and 10 normal healthy nasopharyngeal tissue samples. The differentially-expressed genes (DEGs) were screened using the linear models for microarray data package in R. Using Database for Annotation, Visualization and Integrated Discovery software, potential functions of the DEGs were predicted by Gene Ontology and pathway enrichment analyses. With the information from the Search Tool for the Retrieval of Interacting Genes/Proteins database, the protein protein interaction (PPI) network was visualized by Cytoscape. Furthermore, modules of the PPI network were searched using ClusterONE in Cytoscape. A total of 951 DEGs were screened in the NPC samples compared with the normal healthy nasopharyngeal tissue samples. Function enrichment indicated that the upregulated genes were associated with the cell cycle, cytoskeleton organization and DNA metabolism. Meanwhile, the downregulated genes were mainly associated with cell differentiation, hormone metabolism, inflammatory response and immune response. PPI networks for the DEGs suggested that upregulated mitotic arrest deficient 2 like 1 (MAD2L1; degree=133), proliferating cell nuclear antigen (PCNA; degree=125) and cyclin B1 (CCNB1; degree=115), and downregulated member A1 of aldehyde dehydrogenase 1 (ALDH1A1; degree=15) may be of great importance as they exhibited higher degrees on interaction. Mucin 1 (MUC1) was a key node of module 4. Overall, the study indicated that MAD2L1, CCNB1, PCNA, ALDH1A1 and MUC1 may have a correlation with EBV-associated NPC. PMID- 27698803 TI - Expression and potential correlation among Forkhead box protein M1, Caveolin-1 and E-cadherin in colorectal cancer. AB - The aim of the present study was to investigate the expression and functions of Forkhead box protein M1 (FoxM1), Caveolin-1 (Cav-1) and E-cadherin in colorectal cancer (CRC), and to determine the correlations among these proteins in CRC development and progression. The protein expression of FoxM1, Cav-1 and E cadherin was identified using a human CRC and normal tissue microarray. A standard immunohistochemistry assay was performed employing anti-FoxM1, anti-Cav 1 and anti-E-cadherin antibodies. The clinicopathological significance of FoxM1, Cav-1 and E-cadherin in CRC was determined, and correlations were investigated between FoxM1 and Cav-1, FoxM1 and E-cadherin, Cav-1 and E-cadherin, respectively. The level of FoxM1, Cav-1 and E-Cadherin protein expression in CRC was found to be associated with pathological grade, tumor clinical stages and the presence of metastasis, respectively. Elevated expression of FoxM1 and Cav-1 was observed in the CRC tissues, and a significant correlation was found between the two proteins in CRC. However, it was also observed that FoxM1 was overexpressed while E-cadherin expression was low, indicating that there was a negative correlation between FoxM1 expression and E-cadherin expression. Moreover, there was also a negative correlation between Cav-1 and E-cadherin expression. Overall, the elevated expression of FoxM1 and Cav-1 in a human CRC microarray provided novel clinical evidence to elucidate the fact that they may play a critical role in the development and progression of CRC by negatively regulating E-cadherin expression. Furthermore, the positive correlation between FoxM1 and Cav-1 suggested that the proteins may constitute a novel signaling pathway in human CRC. PMID- 27698804 TI - Entrance of the Tat protein of HIV-1 into human uterine cervical carcinoma cells causes upregulation of HPV-E6 expression and a decrease in p53 protein levels. AB - The infection of uterine cervical epithelial cells by oncogenic, high-risk human papilloma viruses (HR-HPVs) may lead to the development of cervical carcinoma. Of note, the incidence of this tumor is significantly increased in women infected by both HR-HPV and human immunodeficiency virus (HIV)-1. In this regard, previous studies have linked the HIV-1 Tat protein, a trans-activator of viral gene expression, to the pathogenesis of HIV-associated malignancies. In particular, it has been shown that upon its release by acutely infected cells, Tat protein can enter human cells, thus modifying their phenotype. Based on these findings, the present study evaluated whether extracellular Tat protein could be taken up by human uterine cervical carcinoma cells, and whether this could affect the expression of HPV (E6 or E7) or cellular (p16 or p53) molecules, which are key to cervical carcinoma development or progression. The results indicated that extracellular, biologically active HIV-1 Tat protein is taken up by human uterine cervical carcinoma cells, and that this is followed by an increase in the expression of the E6 protein of HPV, and by a reduction in the protein levels of the cellular oncosuppressor p53. Since p53 loss is associated with cell dedifferentiation and immortalization, these findings suggest a possible link between extracellular Tat protein and the high incidence and clinical aggressiveness of uterine cervical carcinoma observed in HIV/HPV doubly infected women. PMID- 27698805 TI - Genetic landscape of a case of extraovarian peritoneal serous papillary carcinoma. AB - The present report aimed to study genetic alterations underlying extraovarian peritoneal serous papillary carcinoma (EPSPC), which have not previously been systematically investigated. A case of EPSPC was identified, and its genetic alterations were assessed by combining comparative genomic hybridization and whole-exome sequencing technologies to investigate the genomic landscape, including copy number variations and mutations in EPSPC. It was found that a large number of germline mutations were present, which may have predisposed the patient to the occurrence of this disease. Copy number gains were found in a range of chromosomes, including 4q, 5q, 8q, 10q, 15q, 16p, 18q, 20p, 20q and Xq. Large-scale copy number loss occurred in chromosomes 2p, 13q, 16q, 17p and 17q. Through use of whole-exome sequencing, germline mutations were widely found that were associated with cancer development, including mutations in the BRCA1, DNA repair associated (BRCA1), BRCA2, tumor protein 53, erb-b2 receptor tyrosine kinase 2, matrix metalloproteinases and ADAM metallopeptidase domain-containing genes. In addition, 165 somatic mutations, including 52 missense mutations and 7 short insertions or deletions, were also identified. In summary, the EPSPC was undergoing profound genomic rearrangement and somatic mutation, which may have led to its initiation and development, and the present study discussed the genetic basis of this highly malignant cancer. PMID- 27698807 TI - Negative pathology of ureteral carcinoma significantly delaying the diagnosis of the primary tumor of osteoblastic metastases: A case report and review of the literature. AB - Ureteral urothelial carcinoma (UC) is a rare malignant tumor. The most common clinical manifestations of ureteral UC are hematuria, increased urinary frequency, dysuria and pain. The diagnosis of ureteral UC is made via radiography, endoscopy and pathology. Although osteoblastic destruction is usually observed in metastasis of prostate cancer, UC can also be a reason for osteoblastic metastasis. The present study reports the case of a 66-year-old man presenting with osteoblastic metastases, in which the primary tumor was finally diagnosed as a ureteral UC. However, the lack of pathological evidence significantly delayed the diagnosis of the primary tumor (>6 months), even though the results of radiographic examination, and the type and mode of bone metastases significantly suggested a ureteral UC. The case reveals that a suitable screening test should be recommended for patients at high risk due to the possibility of a negative pathology result for ureteral UC. Additionally, a more efficient diagnostic method is required. Moreover, the possibility of new diagnostic criterion that do not rely on the pathology of primary foci in ureteral UC should be considered in future. PMID- 27698806 TI - Matrix metalloproteinase expression and molecular interaction network analysis in gastric cancer. AB - Gastric cancer (GC) is one of the most common types of cancer of the digestive tract. Invasion of tumor cells into surrounding tissue and metastasis are among the most significant checkpoints in tumor progression. It is known that matrix metalloproteinases (MMPs) are involved in these processes; however, knowledge of their molecular interaction networks is still limited. Investigation of these networks could provide a more comprehensive picture of the function of MMPs in tumorigenesis. Furthermore, it could be used to develop new approaches to targeted anticancer therapy. In this study, we performed microarray analysis, and 1666 genes that were aberrantly expressed in GC tissues were identified (fold change >2, P<0.05). In addition, quantitative polymerase chain reaction analysis has confirmed that MMP1, MMP3, MMP7, MMP10, MMP11 and MMP12 expression is upregulated in GC. In addition, the MMP3 expression level was negatively correlated with GC differentiation (P<0.05). By integrating the microarray information and BioGRID and STRING databases, we constructed an MMP-related molecular interaction network and observed that 18 genes (including MMPs) were highly expressed in GC tissues. The most enriched of these 18 genes in the Gene Oncology (GO) and pathway analysis were in extracellular matrix disassembly (GO biological process) and extracellular matrix-receptor interaction (KEGG pathway), which are closely correlated with cancer invasion and metastasis. Collectively, our results suggest that the MMP-related interaction network has a role in GC progression, and therefore further studies are required in order to investigate these network interactions in tumorigenesis. PMID- 27698808 TI - Increase of T and B cells and altered BACH2 expression patterns in bone marrow trephines of imatinib-treated patients with chronic myelogenous leukaemia. AB - The effect of imatinib on T and B cells in patients with chronic myelogenous leukaemia (CML) is not well understood. An upregulation of the transcription factor Broad-complex-Tramtrack-Bric-a-Brac and Cap'n'collar 1 bZip transcription factor 2 (BACH2), which is involved in the development and differentiation of B cells, was demonstrated in a CML cell line treated with imatinib. The present study retrospectively analysed the expression and distribution of cluster of differentiation (CD)3, CD20 and BACH2 (per 1,000 cells), as well as the co expression of CD20 and BACH2, using immunohistochemistry in serial bone marrow trephines obtained from 14 CML patients treated with imatinib in comparison to 17 patients with newly diagnosed CML and 6 control trephines. Bone marrow trephines of CML patients in remission under imatinib therapy exhibited significantly higher numbers of CD3 and CD20 infiltrates (partly ordered in aggregates) compared with patients with newly diagnosed CML and control individuals. Similarly, nuclear expression of BACH2 in granulopoietic cells was increased in CML patients treated with imatinib, which may represent the histological correlate of the positive treatment effect. Furthermore, since BACH2 is involved in B cell development, its altered expression patterns by imatinib may be one explanation for high B cell numbers, as revealed by CD20/BACH2 (nuclear)-positive cells. As the present data are preliminary, future prospective studies are required to assess the prognostic and predictive role of BACH2 in patients with CML under targeted therapy. PMID- 27698809 TI - Expression and prognostic significance of CTBP2 in human gliomas. AB - Deregulated expression of C-terminal-binding protein 2 (CTBP2) has been observed previously in a number of tumors, such as hepatocellular carcinoma and prostatic cancer, in the colorectal cancer SW480 cell line and in the human embryonic kidney 293 cell line. In the present study, western blot analysis and immunohistochemistry were performed to investigate whether gliomas exhibit deregulated CTBP2 expression. Kaplan-Meier survival analyses were performed to evaluate the associations between CTBP2 expression, clinicopathological data and patient survival in glioma patients. The results revealed that CTBP2 expression was significantly upregulated in high grade glioma tissues compared with that in low grade glioma and normal brain tissues. Furthermore, increased CTBP2 expression in gliomas was significantly associated with a higher World Health Organization (WHO) tumor grade (P<0.005) and poorer disease-specific survival (P<0.005). In conclusion, these results suggest that CTBP2 may act as an intrinsic regulator of progression in glioma cells and thus may serve as an important prognostic factor for the disease. PMID- 27698810 TI - Association between SET expression and glioblastoma cell apoptosis and proliferation. AB - Glioblastoma multiforme (GBM) was one of the first cancer types systematically studied at a genomic and transcriptomic level due to its high incidence and aggressivity; however, the detailed mechanism remains unclear, even though it is known that numerous cytokines are involved in the occurrence and development of GBM. The present study aimed to determine whether the SET gene has a role in human glioblastoma carcinogenesis. A total of 32 samples, including 18 cases of glioma, 2 cases of meningioma and 12 normal brain tissue samples, were detected using the streptavidin-peroxidase method through immunohistochemistry. To reduce SET gene expression in U251 and U87MG cell lines, the RNA interference technique was used and transfection with small interfering (si)RNA of the SET gene was performed. Cell apoptosis was detected by flow cytometry, cell migration was examined by Transwell migration assay and cell proliferation was determined by Cell Counting Kit-8. SET, Bcl-2, Bax and caspase-3 mRNA and protein expression levels were detected by reverse transcription-quantitative polymerase chain reaction and western blot analysis, respectively. Positive protein expression of SET was observed in the cell nucleus, with the expression level of SET significantly higher in glioma tissues compared with normal brain tissue (P=0.001). Elevated expression of SET was significantly associated with gender (P=0.002), tumors classified as World Health Organization grade II (P=0.031), III (P=0.003) or IV (P=0.001), and moderately (P=0.031) or poorly differentiated (P=0.001) tumors. Compared with the negative and non-treatment (blank) control cells, SET gene expression was significantly inhibited (P=0.006 and P<0.001), cell apoptosis was significantly increased (P=0.001 and P<0.001), cell proliferation was significantly inhibited (P=0.002 and P=0.015), and cell migration was significantly decreased (P=0.001 and P=0.001) in siRNA-transfected U87MG-SET and U251-SET cells, respectively. In addition, mRNA and protein expression levels of Bcl-2 were significantly inhibited in U87MG-SET and U251-SET cells, while mRNA and protein expression levels of Bax and caspase-3 were significantly increased, compared with the two control groups. Thus, the current data suggests that SET may regulate the proliferation and apoptosis of glioblastoma cells by upregulating Bcl-2, and downregulating Bax and caspase-3. PMID- 27698811 TI - Expression of FoxM1 and the EMT-associated protein E-cadherin in gastric cancer and its clinical significance. AB - The aim of the present study was to investigate the expression of forkhead box M1 (FoxM1) and E-cadherin in tissues of gastric cancer in order to reveal any correlation between FoxM1, E-cadherin and clinicopathological parameters. The association between FoxM1 and E-cadherin in the development and progression of gastric cancer was also investigated. The expression of FoxM1 and E-cadherin in gastric cancer and adjacent normal tissue on tissue microarray was detected using immunohistochemistry. The clinicopathological significance of FoxM1 and E cadherin in gastric cancer was explored, and the association between FoxM1 and E cadherin was further examined using statistical techniques. In gastric cancer tissues, the expression of FoxM1 and E-cadherin was strongly positive, but it was weak in normal gastric mucosa. Overexpression of FoxM1 was evident in gastric cancer, and was associated with poor tumor differentiation (P<0.05), advanced tumor state (P<0.05) and lymph node (or distant) metastasis (P<0.05), whereas E cadherin had the opposite effects. Furthermore, the correlation between FoxM1 and E-cadherin expression in gastric cancer tissue was negative. In conclusion, the high FoxM1 expression and low E-cadherin expression in gastric cancer tissue suggests that these proteins play a critical role in the development and progression of gastric cancer. PMID- 27698812 TI - Ultrasonic features of papillary thyroid microcarcinoma coexisting with a thyroid abnormality. AB - The present study aimed to investigate the value of ultrasonography in the diagnosis of papillary thyroid microcarcinoma (PTMC) coexisting with a thyroid abnormality, and to improve the accuracy of PTMC diagnosis. The ultrasonic features of 38 PTMC nodules coexisting with a thyroid abnormality and 56 thyroid benign nodules, obtained by surgical resection and confirmed by pathological analysis, were retrospectively analyzed. All masses were <= 1.0 cm in diameter. Ultrasonic features that were analyzed included the shape, aspect ratio, boundary, margin, echo, uniformity, presence or absence of microcalcification and enlargement of the lymph nodes, as well as the blood flow of the nodules. Furthermore, the sensitivity, specificity and accuracy of ultrasonography for the diagnosis of PTMC were obtained. The following ultrasonic features of thyroid nodules were significantly (P<0.05) associated with PTMC coexisting with a thyroid abnormality: An irregular shape; an aspect ratio of >= 1; an unclear boundary; blurred margins; internal heterogeneous hypoechogenicity; and microcalcification. Therefore, thyroid nodules with these ultrasonic characteristics coexisting with a thyroid abnormality may be suspected as malignant PTMC. The present study demonstrated that ultrasound-guided biopsies are necessary to prevent misdiagnosis of PTMC. The sensitivities of enlarged neck lymph nodes and abundant blood flow are so low that they may be considered as references for the differentiation of PTMC from benign nodules. PMID- 27698813 TI - Screening glioma stem cells in U251 cells based on the P1 promoter of the CD133 gene. AB - Cluster of differentiation (CD)133 is an important cell surface marker of glioma stem cells (GSCs). The transcription of the CD133 gene is controlled by five alternative promoters (P1, P2, P3, P4 and P5), which are expressed in a tissue specific manner. In the present study, gene recombination technology was used to construct two types of gene expression vectors that contained the P1 promoter of the CD133 gene, which regulated either the neomycin-resistance gene or the herpes simplex virus thymidine kinase (HSV-TK) gene. Following the stable transfection of U251 glioblastoma cells with these two gene vectors, the cells expressing the P1 promoter that regulated the neomycin-resistance gene were named CD133 (+) cells, while the cells expressing the P1 promoter regulating the HSV-TK gene were called CD133 (-) cells. The expression of CD133 was detected by flow cytometry and reverse transcription-quantitative polymerase chain reaction. The 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was used to assess cell proliferation ability, while the cell cycle was analyzed by flow cytometry, and a clone formation test was performed to evaluate the invasive capability of the cells. The results demonstrated that, due to CD133 expression, the cell proliferation ability and the invasive capability of CD133 (+) cells were significantly higher than those of CD133 (-) cells. In conclusion, the present study successfully established a novel method of screening GSCs in U251 cells based on the P1 promoter of the CD133 gene. PMID- 27698814 TI - Effect of API-1 and FR180204 on cell proliferation and apoptosis in human DLD-1 and LoVo colorectal cancer cells. AB - The activation of the phosphatidylinositol-3 kinase/v-akt murine thymoma viral oncogene homolog (Akt) and mitogen activated protein kinase kinase/extracellular signal-regulated kinase (ERK) pathways are implicated in the majority of cancers. Selective inhibition of Akt and ERK represents a potential approach for cancer therapy. Therefore, the present study aimed to investigate the apoptotic and anti proliferative effects of the novel and selective Akt inhibitor 4-amino-5,8 dihydro-5-oxo-8-beta-D-ribofuranosyl-pyrido[2,3-d]pyrimidine-6-carboxamide (API 1) and selective ERK1/2 inhibitor FR180204 (FR) alone and in combination on colorectal cancer (CRC) cells (DLD-1 and LoVo). In addition, the effects of API-1 and FR on Akt and ERK signaling pathways were also investigated. The effects of the agents on DLD-1 and LoVo cells were evaluated in terms of cell viability, cytotoxicity, DNA synthesis rate, DNA fragmentation and caspase-3 activity levels. In addition, quantitative reverse transcription-polymerase chain reaction and western blot analysis were performed to examine relevant mRNA and protein levels. The present study observed that the combination of FR with API-1 resulted in significant apoptosis and cytotoxicity compared with any single agent alone in a time-dependent manner in these cells. Also, treatment with FR and API-1 in combination decreased the expression levels of B-cell lymphoma-2 (BCL2), Bcl-2 like1, cyclin D1 and cMYC, and increased the expression levels of BCL2-associated X protein and BCL2 antagonist/killer via phosphorylated Akt and phosphorylated ERK1/2 downregulation. The combination of Akt and ERK1/2 inhibitors resulted in enhanced apoptotic and anti-proliferative effects against CRC cells. The present study hypothesizes that the combination of FR and API-1 in CRC cells may contribute toward potential anti-carcinogenic effects. Additional analyses using other cancer cell lines and animal models are required to confirm these findings in vitro and in vivo. PMID- 27698815 TI - Clinical analysis of 47 cases of solitary fibrous tumor. AB - The aim of the present study was to summarize the clinical manifestations, diagnosis, treatment, and prognosis of solitary fibrous tumor (SFT). In total, 47 cases of SFTs diagnosed by postoperative pathology between January 2002 and September 2014 were retrospectively reviewed, and the general information, clinical manifestations, imaging techniques, treatment, pathology and follow-up findings were analyzed. Of the 47 patients, clinical characteristics were collected in 37 cases (18 men and 19 women; mean age, 44.1 years; age range, 13 72 years). The maximum diameters of the tumors were 1.5-25 cm, with a mean diameter of 8.8 cm. The symptoms were various and non-specific. Imaging examinations following iodinated contrast administration showed the SFTs to be well-defined, cystic or solid mass and enhanced. On color Doppler ultrasound, SFTs were described as hypoechoic, clear, irregular masses. All patients underwent surgical resection, and SFT was diagnosed by postoperative pathological and immunohistochemical examination. Of the 47 patients, 25 received complete follow-up of 5-130 months, with a median follow-up period of 35.2 months, that included a color Doppler ultrasound or computed tomography (CT) scan every 6-12 months. At the end of the follow-up period all patients were alive and healthy, with the exception of one patient, who presented with recurrence 15 months after surgery. The findings of the present study showed SFT to be a rare systemic disease with no particular clinical manifestations. In the cases reviewed in the present study, CT, magnetic resonance imaging scans and color Doppler ultrasound were important for the diagnosis of SFT, while the definitive diagnosis relied on pathological and immunohistochemical examinations. Surgery, the primary treatment for SFT, was performed, and, following complete removal of the tumor, the prognosis was favorable. PMID- 27698816 TI - Evaluation of automated breast volume scanner for breast conservation surgery in ductal carcinoma in situ. AB - The present is a retrospective study examining the use of automated breast volume scanner (ABVS) for guiding breast conservation surgery in ductal carcinoma in situ (DCIS). A total of 142 patients with pathologically confirmed DCIS were initially included in the study. The patients underwent preoperative examination by conventional ultrasound and by ABVS. The BI-RADS category system was used to identify benign and malignant lesions, after which breast conservation surgery was performed, and the therapeutic effects were compared. DCIS lesions were found in each quadrant of the breasts. Typical symptoms included: Duct ectasia and filling in 23 cases, mass (mainly solid, occasionally cystic, with or without calcification) in 38 cases, hypoechoic area (with or without calcification) in 33 cases, calcifications (simple) in 23 cases, and architectural distortion in 17 cases. In addition, 110 cases (82.1%) were detected as grade >=4 according to the BI-RADS category, and 92 cases (68.7%) were considered malignant lesions following conventional ultrasound scanning. The detection rate of ABVS was significantly higher than that of conventional ultrasound (chi2=268.000, P<0.001). The average tumor diameter was 2.5+/-0.8 cm using ABVS and 2.0+/-0.9 cm using conventional ultrasound (the former being significantly higher than the latter; t=6.325, P=0.034). Eight patients (5.6%) had recurrences of the cancer, and the tumor diameter in the 8 patients was significantly larger using ABVS as compared to conventional ultrasound. In the diagnosis of DCIS, ABVS was superior to conventional ultrasound scanner in guiding breast conservation surgery and predicting recurrence. However, large-scale studies are required for confirmation of the findings. PMID- 27698817 TI - Stem cell growth factor receptor in canine vs. feline osteosarcomas. AB - Osteosarcoma is considered the most common bone cancer in cats and dogs, with cats having a much better prognosis than dogs, since the great majority of dogs with osteosarcoma develop distant metastases. In search of a factor possibly contributing to this disparity, the stem cell growth factor receptor KIT was targeted, and the messenger (m)RNA and protein expression levels of KIT were compared in canine vs. feline osteosarcomas, as well as in normal bone. The mRNA expression of KIT was quantified by reverse transcription-quantitative polymerase chain reaction, and was observed to be significantly higher in canine (n=14) than in feline (n=5) osteosarcoma samples (P<0.001). KIT protein expression was evaluated by immunohistochemistry, which revealed that 21% of canine osteosarcoma samples did not exhibit KIT staining in their neoplastic cells, while in 14% of samples, a score of 1 (<10% positive tumour cells) was observed, and in 50% and 14% of samples, a score of 2 (10-50% positivity) and 3 (>50% positivity), respectively, was observed. By contrast, the cancer cells of all the feline bone tumour samples analysed were entirely negative for KIT. Notably, canine and feline osteocytes of healthy bone tissue lacked any KIT expression. These results could be the first evidence that KIT may be involved in the higher aggressiveness of canine osteosarcoma compared with feline osteosarcoma. PMID- 27698818 TI - The HIV-protease inhibitor saquinavir reduces proliferation, invasion and clonogenicity in cervical cancer cell lines. AB - Innovative therapies in cervical cancer (CC) remain a priority. Recent data indicate that human immunodeficiency virus (HIV)-protease inhibitors used in highly active antiretroviral therapy can exert direct antitumor activities also in HIV-free preclinical and clinical models. The aim of the present study was to evaluate the antineoplastic effects of various HIV-protease inhibitors (indinavir, ritonavir and saquinavir) on primary and established CC cell lines. Two CC cell lines established in our laboratory and four commercially available CC cell lines were treated with indinavir, ritonavir and saquinavir at different concentrations and for different times. Proliferation, clonogenicity and radiosensitivity were evaluated by crystal violet staining. Proteasomal activities were assessed using a cell-based assay and immunoblotting. Cell cycle was analyzed by propidium iodide staining and flow cytometric analysis. Invasion was tested with Matrigel chambers. A t-test for paired samples was used for statistical analysis. In all cell lines, saquinavir was more effective than ritonavir in reducing cell proliferation and inhibiting proteasomal activities (P<=0.05). Conversely, indinavir exerted a negligible effect. The saquinavir concentrations required to modulate the proteasome activities were higher than those observed to be effective in inhibiting cell proliferation. In HeLa cells, saquinavir was strongly effective in inhibiting cell invasion and clonogenicity (P<=0.05) at concentrations much lower than those required to perturb proteasomal activities. Saquinavir did not contribute to increase the sensitivity of HeLa cells to X-rays. In conclusion, the present results demonstrate that saquinavir is able to significantly reduce cell proliferation, cell invasion and clonogenicity in a proteasome-independent manner in in vitro models of CC, and suggest that saquinavir could be a promising CC therapeutic agent. PMID- 27698819 TI - Significance of stem cell marker Nanog gene in the diagnosis and prognosis of lung cancer. AB - The aim of the present study was to analyze the stem cell marker, Nanog gene, for the diagnosis and prognosis of lung cancer cases, and to study its application in the diagnosis of lung cancer. In total, 100 patients diagnosed with lung cancer between April, 2013 and May, 2015 were included in the present study. The patients were randomly divided into group A (lung cancer) and group B (squamous cell lung carcinoma). RT-PCR was used to detect the cancer and adjacent tissues, and Nanog gene expression was detected in groups A and B in cells. The results showed that, analysis of Nanog gene expression in the two groups of patients varied to different degrees. There was no significant difference between the two groups with regard to age, gender, disease stage and lymph node metastasis. Nanog gene expression in patients with carcinoma were significantly higher than that in the adjacent tissues (p<0.05). By contrast, differentiated and well differentiated carcinoma tissue showed a significantly higher Nanog gene expression than poorly differentiated and undifferentiated carcinoma (p<0.05). The expression of Nanog in normal cells was significantly higher than that in normal lung tissues and benign lesions in lung cancer stem cells. Nanog was highly expressed in CD44+ cells, and Nanog expression in lung cancer stem cells was significantly higher (p<0.05). In conclusion, for groups A (lung cancer) and B (squamous cell lung carcinoma) the Nanog gene expression was significantly higher. The data of the present study show that the patients with stage III and IV lung cancer had a higher Nanog gene expression. In addition, there was a higher expression of Nanog in lung cancer patients. By contrast, a lower degree of cell differentiation was associated with strong Nanog gene expression in lung cancer. PMID- 27698820 TI - Hepatocellular carcinoma stem cell-like cells are enriched following low-dose 5 fluorouracil chemotherapy. AB - It has been proposed that cancer stem cells (CSCs) are involved in tumor resistance to chemotherapy and tumor relapse. The goal of the present study was to determine the effect of low-dose 5-fluorouracil (5-Fu) on enriched hepatocellular CSC-like cells. Increased cell motility and epithelial-mesenchymal transition were observed by migration assay in human hepatoblastoma PLC/RAF/5 cells following 5-Fu treatment, as well as a significant enhancement in their sphere-forming abilities. CSC-like cells were identified by side population cell analysis. The percentage of CSC-like cells in the surviving cells was greatly increased in response to 5-Fu. These findings indicate that low-dose 5-Fu treatment may efficiently enrich the CSC-like cell population in PLC/RAF/5 cells. PMID- 27698821 TI - Comparison of the accuracy of 99mTc-3P4-RGD2 SPECT and CT in diagnosing solitary pulmonary nodules. AB - The aim of the present study was to compare technetium-99m-(polyethylene glycol 4)3-(Arg-Gly-Asp)2 (99mTc-3P4-RGD2) single-photon emission computed tomography (SPECT) and computed tomography (CT) in the noninvasive differentiation of solitary pulmonary nodules (SPNs). The present study prospectively investigated a consecutive series of 24 patients with SPN, who were newly diagnosed using radiography between September 2012 and January 2014. All patients underwent 99mTc 3P4-RGD2 SPECT and CT scans using a dual-head variable-angle gamma-camera equipped with high-resolution collimators. A blinded panel of two thoracic radiologists for CT and three nuclear physicians for SPECT analyzed the images using a 5-grade scale. The SPECT images were also semi-quantitatively evaluated using tumor to non-tumor localization ratios (T/NT). The results were verified by pathological examination of the biopsy material obtained from each patient with SPN, and receiver operating characteristic (ROC) curves were generated from these results. The present results revealed that there were 17 malignant and 7 benign SPNs among the 24 patients with SPN. The mean size of the SPN was 2.1+/-0.6 cm. Sensitivity of visual analysis for SPECT and CT were 100.0 and 82.4%, respectively, and specificity was 71.4% for the two methods. When the T/NT SPECT semiquantitative analysis (ratio, 1.64) was used as a cut-off, the sensitivity and specificity of SPECT were 100.0 and 71.4%, respectively. The areas under the ROC curves were 0.840 for visual analysis of SPECT [95% confidence interval (CI), 0.600-1.000], 0.849 for semiquantitative analysis of SPECT (95% CI, 0.618-1.000) and 0.815 for CT (95% CI, 0.626-1.000). In conclusion, the present results suggest that 99mTc-3P4-RGD2 SPECT is more accurate than CT in the detection of malignant SPN, and visual analysis appears to be sufficient for the characterization of SPN. PMID- 27698822 TI - Bioinformatics analysis of the molecular mechanism of diffuse intrinsic pontine glioma. AB - The present study aimed to elucidate key molecular mechanisms in the progression of diffuse intrinsic pontine glioma (DIPG). The gene expression profile GSE50021, which consisted of 35 pediatric DIPG samples and 10 normal brain samples, was downloaded from the Gene Expression Omnibus database. The differentially expressed genes (DEGs) in the pediatric DIPG samples were identified. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) and Reactome pathways of DEGs were enriched and analyzed. The protein-protein interaction (PPI) network of the DEGs was constructed and functional modules of the PPI network were disclosed using ClusterONE. A total of 679 DEGs (454 up- and 225 downregulated) were identified in the pediatric DIPG samples. DEGs were significantly enriched in various GO terms, and KEGG and Reactome pathways. The PPI network of upregulated (153 nodes and 298 connections) and downregulated (71 nodes and 124 connections) DEGs, and two crucial modules, were obtained. Downregulated genes in module 2, such as cholecystokinin (CCK), gastrin (GAST), adenylate cyclase 2 (brain) (ADCY2) and 5-hydroxytryptamine (serotonin) receptor 7 (HTR7), were significantly enriched in the calcium signaling pathway, the neuroactive ligand-receptor interaction pathway and in GO terms, such as the G protein coupled receptor (GPCR) signaling pathway, while upregulated genes in module 1 were not enriched in any pathways or GO terms. CCK and GAST associated with the GPCR signaling pathway, HTR7 enriched in the neuroactive ligand-receptor interaction, and ADCY2 and HTR7 involved in the calcium signaling pathway may be key mechanisms playing crucial roles in the development and progression of DIPG. PMID- 27698823 TI - miRNA-335 and miRNA-182 affect the occurrence of tongue squamous cell carcinoma by targeting survivin. AB - The aim of the present study was to characterize the roles of two microRNAs (miRs) that have been reported to be differentially expressed in tongue squamous cell carcinoma (TSCC), miR-335 and miR-182. In total, 20 tumor tissue samples and 20 corresponding adjacent non-cancerous samples were collected from patients with TSCC to measure the expression of miR-335 and miR-182 and the potential shared target of these miRs, survivin, using reverse transcription-quantitative polymerase chain reaction and western blotting. In the TSCC tissue samples, significantly decreased expression of the two miRs and increased expression of survivin were detected compared with adjacent non-cancerous controls. Subsequently, it was confirmed that survivin was the target gene of miR-335 and miR-182 using a luciferase assay in TSCC cells. In order to examine the function of miR-335 and miR-182 in the development of TSCC, TSCC cells were transiently transfected with the mimics of the two miRs, and it was confirmed that the introduction of miR-335 and miR-182 to cells suppressed the expression of survivin and markedly inhibited the proliferation of the TSCC cells. Furthermore, miR-335 and miR-182 were found to induce cell cycle arrest by suppressing the expression of survivin. The present study revealed a negative regulatory role of miR-335 and miR-182 in the proliferation of TSCC cells by targeting survivin, and miR-335 and miR-182 may be novel therapeutic targets for the treatment of TSCC. PMID- 27698824 TI - miR-101 inhibits glioma cell invasion via the downregulation of COX-2. AB - Glioma is the most common type of primary tumor of the central nervous system. The present study aimed to demonstrate the role of miR-101 and cyclooxygenase-2 (COX-2) in the initiation and development of glioma. The expression of miR-101 and COX-2 in normal and malignant human glial cells and tissues was determined by western blotting and quantitative polymerase chain reaction analysis. The role of miR-101 on COX-2 expression was evaluated by a dual-luciferase reporter assay. The effects of miR-101 and COX-2 in glioma cell proliferation and invasion was verified by CCK-8 test and Transwell assays, respectively. The present study demonstrated that miR-101 expression was downregulated while COX-2 was upregulated in glioma tissues and cells. Furthermore, transfection of miR-101 significantly downregulated COX-2 expression in both U373 and U87 glioma cells. In addition, further experiments revealed that overexpression of miR-101 resulted in significant inhibition of the in vitro proliferation and migration of glioma cells, and the in vivo growth of established tumors. Direct downregulation of COX 2 by transfection with corresponding small interfering RNA also inhibited the proliferation and invasion of glioma cells. These results indicate that downregulation of miR-101 is involved in the initiation and development of glioma via COX-2 upregulation. PMID- 27698826 TI - Effects of ZNF139 on gastric cancer cells and mice with gastric tumors. AB - Gastric cancer (GC) is the fourth most common type of cancer, worldwide. The major molecular factors associated with the pathogenesis of GC remain unclear. Previous studies found that zinc finger proteins are highly abundant in human eukaryotes and tissues, and play an important role in maintaining normal cellular functions and have an association with tumor initiation. In the current study, interference technology was used to silence the ZNF139 protein, a zinc finger protein that was previously found to be closely associated with GC. The results showed that cell viability and proliferation were inhibited in the Znf139 knockdown of GC cells. Additional study found that the expression levels of B cell lymphoma-2 (Bcl-2) and survivin messenger RNAs and proteins were downregulated in Znf139-silenced cells, indicating that cells expression Znf139 are able to induce the growth of tumor cells by mediating the apoptosis pathway. Further in vivo experiments showed that Znf139 knockdown downregulated the expression levels of Bcl-2 and survivin in mice. Overall, the in vitro and in vivo findings of the present study indicate that ZNF139 may be actively involved in the progression of GC. PMID- 27698825 TI - Glioma coexisting with angiographically occult cerebrovascular malformation: A case report. AB - Angiographically occult cerebrovascular malformation (AOVM) is a type of complex cerebrovascular malformation that is not visible on digital subtraction angiography (DSA). Vascular malformation coexisting with glioma is clinically rare, and glioma coexisting with AOVM is even more rare. To the best of our knowledge, the present study is the first to report glioma coexisting with AOVM in the literature. The present study reports a rare case of glioma coexisting with AOVM in a 30-year-old male patient. Computed tomography (CT) scan revealed calcification, hemorrhage and edema in the right frontal lobe. CT angiography revealed a vascular malformation in the right frontal lobe, which was not observed on DSA. Finally, glioma coexisting with AOVM was confirmed by 2.0T magnetic resonance imaging and postoperative pathological examination. The present patient had a positive outcome and no neurological dysfunctions during the 6-month follow-up subsequent to surgery. PMID- 27698827 TI - Prognostic significance of CD168 overexpression in colorectal cancer. AB - The expression of cluster of differentiation 168 (CD168), a cell surface receptor for hyaluronan, is associated with cancer progression and metastases. The aim of the present study was to analyze the expression of CD168 by immunohistochemistry in colorectal cancer (CRC) and to examine the association between CD168 expression and clinicopathological features, including survival. A total of 78 tissue specimens obtained from consecutive CRC patients exhibiting various tumor node metastasis (TNM) stages were immunostained for the analysis of CD168 expression. The prognostic value of CD168 was subsequently evaluated. Kaplan Meier survival analysis revealed that CD168 overexpression was significantly associated with overall survival (P<0.05); however, no significant association was identified between CD168 expression and tumor location, tumor differentiation or TNM stage. Overexpression of CD168 was closely associated with poorer patient survival, which indicates that it may present a useful indicator for clinical prognosis. PMID- 27698828 TI - Autophagy inhibition augments resveratrol-induced apoptosis in Ishikawa endometrial cancer cells. AB - Resveratrol (RSV), a polyphenolic compound derived from red wine, inhibits the proliferation of various types of cancer. RSV induces apoptosis in cancer cells, while enhancing autophagy. Autophagy promotes cancer cell growth by driving cellular metabolism, which may counteract the effect of RSV. The present study aimed to elucidate the correlation between RSV and autophagy and to examine whether autophagy inhibition may enhance the antitumor effect of RSV in endometrial cancer cells. Cell proliferation, cell cycle progression and apoptosis were examined, following RSV exposure, by performing MTT assays, flow cytometry and annexin V staining, respectively, in an Ishikawa endometrial cancer cell line. Autophagy was evaluated by measuring the expression levels of light chain 3, II (LC3-II; an autophagy marker) by western blotting and immunofluorescence. Chloroquine (CQ) and small interfering RNAs targeting autophagy related (ATG) gene 5 (ATG5) or 7 (ATG7) were used to inhibit autophagy, and the effects in combination with RSV were assessed using MTT assays. RSV treatment suppressed cell proliferation in a dose-dependent manner in Ishikawa cells. In addition, RSV exposure increased the abundance of the sub-G1 population and induced apoptosis. LC3-II accumulation was observed following RSV treatment, indicating that RSV induced autophagy. Combination treatment with CQ and RSV more robustly suppressed growth inhibition and apoptosis, compared with RSV treatment alone. Knocking down ATG5 or ATG7 expression significantly augmented RSV-induced apoptosis. The results of the present study indicated that RSV-induced autophagy may counteract the antitumor effect of RSV in Ishikawa cells. Combination treatment with RSV and an autophagy inhibitor, such as CQ, may be an attractive therapeutic option for treating certain endometrial cancer cells. PMID- 27698829 TI - MicroRNA-486-5p enhances hepatocellular carcinoma tumor suppression through repression of IGF-1R and its downstream mTOR, STAT3 and c-Myc. AB - The insulin-like growth factor (IGF)-axis has been paradigmatically involved in hepatocellular carcinoma (HCC) tumor initiation, progression and drug resistance. Consequently, members of the IGF-axis and most importantly, IGF-1 receptor (IGF 1R) have been considered as intriguing targets for HCC therapy. Few miRNAs have been recently reported to be associated with IGF-1R regulation. The present study aimed to investigate the role of microRNA (miRNA/miR)-486-5p in the regulation of IGF-1R and its downstream signaling cascades. miR-486-5p was markedly downregulated in hepatitis C virus-induced HCC tissues and Huh-7 cells. Forcing the expression of miR-486-5p in Huh-7 cells resulted in the repression of IGF-1R, mammalian target of rapamycin (mTOR), signal transducer and activator of transcription 3 (STAT3) and c-Myc mRNA levels. Ectopic expression of miR-486-5p in Huh-7 cells markedly repressed cellular viability, proliferation, migration and clonogenicity in a similar pattern to IGF-1R small interfering RNAs, and were evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, BrdU incorporation, wound healing and colony forming assays, respectively. Overall, the study findings demonstrated that miR-486-5p acts as a tumor suppressor in HCC through the repression of essential members of the IGF-axis, including IGF-1R and its downstream mediators mTOR, STAT3 and c-Myc. PMID- 27698830 TI - 17AAG-induced internalisation of HER2-specific Affibody molecules. AB - The geldanamycin derivative 17-allylamino-17-demethoxygeldanamycin (17-AAG) is known to induce internalisation and degradation of the otherwise internalisation resistant human epidermal growth factor receptor 2 (HER2) receptor. In the present study, 17-AAG was used to increase internalisation of the HER2-specific Affibody molecule ABY-025. The cellular redistribution of halogen-labelled 211At ABY-025 and radiometal-labelled 111In-ABY-025 following treatment with 17-AAG was studied. 17-AAG treatment of SKOV-3 human ovarian carcinoma and SKBR-3 human breast carcinoma cells to some extent shifted the localisation of 111In-ABY-025 from the cell surface to intracellular compartments in the two cell lines. ABY 025 labelled with the high-linear energy transfer alpha emitter 211At was also internalised to a higher degree; however, due to its physiological properties, this nuclide was excreted faster. The results indicate that 17-AAG may be used to facilitate cell-specific intracellular localisation of a suitable cytotoxic or radioactive agent coupled to ABY-025 in HER2-overexpressing cells. PMID- 27698831 TI - Suppression of the Eag1 potassium channel sensitizes glioblastoma cells to injury caused by temozolomide. AB - Glioblastoma multiforme (GBM) is the most aggressive type of human primary brain tumor. The standard treatment protocol includes radiotherapy in combination with temozolomide (TMZ). Despite advances in GBM treatment, the survival time of patients diagnosed with glioma is 14.5 months. Regarding tumor biology, various types of cancer cell overexpress the ether a go-go 1 (Eag1) potassium channel. Therefore, the present study examined the role of Eag1 in the cell damage caused by TMZ on the U87MG glioblastoma cell line. Eag1 was inhibited using a channel blocker (astemizole) or silenced by a short-hairpin RNA expression vector (pKv10.1-3). pKv10.1-3 (0.2 ug) improved the Eag1 silencing caused by 250 uM TMZ, as determined by reverse transcription-quantitative polymerase chain reaction and immunocytochemistry. Additionally, inhibiting Eag1 with the vector or astemizole (5 uM) reduced glioblastoma cell viability and sensitized cells to TMZ. Cell viability decreased by 63% for pKv10.1-3 + TMZ compared with 34% for TMZ alone, and by 77% for astemizole + TMZ compared with 46% for TMZ alone, as determined by MTT assay. In addition, both the vector and astemizole increased the apoptosis rate of glioblastoma cells triggered by TMZ, as determined by an Annexin V apoptosis assay. Collectively, the current data reveal that Eag1 has a role in the damage caused to glioblastoma by TMZ. Furthermore, suppression of this channel can improve the action of TMZ on U87MG glioblastoma cells. Thus, silencing Eag1 is a promising strategy to improve GBM treatment and merits additional studies in animal models of glioma. PMID- 27698832 TI - Prognostic value of serum carbonic anhydrase IX in testicular germ cell tumor patients. AB - Despite the fact that testicular germ cell tumors (TGCTs) are one of the most chemosensitive solid tumors, a small proportion of patients fail to be cured following cisplatin-based first line chemotherapy. Upregulation of carbonic anhydrase IX (CA IX) in various solid tumors is associated with poor outcome. The current prospective study investigated the prognostic value of serum CA IX level in TGCTs. In total, 83 patients (16 non-metastatic following orchiectomy with no evidence of disease, 57 metastatic chemotherapy-naive and 10 metastatic relapsed chemotherapy-pretreated) starting adjuvant and/or new line of chemotherapy and 35 healthy controls were enrolled in the study. Serum CA IX values were determined using an enzyme-linked immunosorbent assay, and intratumoral CA IX was analyzed by immunohistochemistry. Metastatic chemotherapy-naive patients had significantly higher mean CA IX serum levels than healthy controls (490.6 vs. 249.6 pg/ml, P=0.005), while there was no difference in serum CA IX levels in non-metastatic or relapsed TGCT patients compared with healthy controls. There was no significant difference in the mean serum CA IX levels between different groups of patients and between the first and second cycle of chemotherapy, nor association with patients/tumor characteristics. Serum CA IX was not prognostic for progression-free survival [hazard ratio (HR)=0.81, P=0.730] or overall survival (HR=0.64, P=0.480). However, there was a significant association between intratumoral CA IX expression and serum CA IX concentration (rho=0.51, P=0.040). These results suggest that serum CA IX level correlates with tumor CA IX expression in TGCT patients, but fails to exhibit either a prognostic value or an association with patients/tumor characteristics. PMID- 27698833 TI - Cisplatin-resistant osteosarcoma cells possess cancer stem cell properties in a mouse model. AB - Osteosarcoma is the most common malignancy of the bones, and although advances in chemotherapy and surgery had been achieved in recent years, the long-term survival rate has reached a plateau. The main reason for this is the aggressive malignant potential and poor response of the disease to chemotherapy. However, several studies have found that tumor resistance is associated with cancer stem cells (CSCs). To address this issue, in the present study, osteosarcoma cells were treated with specially designated concentrations of cisplatin (CDDP) in a mouse model. Hematoxylin and eosin staining analyses were performed to assess tissue structure, in vivo passaging and CDDP treatment. Drug resistance genes and well-established stemness genes were detected by quantitative polymerase chain reaction. A serum-starved sphere formation assay was adopted to evaluate the ability to generate spherical clones and flow cytometry as used to test the expression of the cluster of differentiation 117 and Stro-1 surface markers, known as markers of CSCs. It was found that CDDP could induce an effect of resistance in the osteosarcoma cells, which possessed cancer stem CSC properties, as shown by the elevated expression of CSC marker genes and the higher expression of the cluster of differentiation 117 and Stro-1 surface markers. Moreover, the cells that dissociated from the tumor tissues exhibited an increased ability to form sarcospheres. The results of this study provided a significant correlation between resistance and CSCs, and revealed a clue indicating that osteosarcoma recurrence is likely to be associated with CSCs. PMID- 27698834 TI - Decreased sirtuin 4 expression is associated with poor prognosis in patients with invasive breast cancer. AB - Aberrant metabolism is a hallmark of human cancer. Glutamine metabolism has been identified as a central metabolic pathway in cancer and thus, targeting glutamine metabolism may exhibit therapeutic potential. Sirtuin 4 (SIRT4) is an important molecule that mediates the blockade of glutamine catabolism by inhibiting glutamate dehydrogenase. In the present study, SIRT4 protein expression levels were analyzed in 409 breast cancer tissues and 241 paired adjacent non-cancerous tissues by immunohistochemical analysis and the correlation between SIRT4 expression and the clinicopathological features was evaluated. SIRT4 protein was markedly increased in the breast cancer cells compared with adjacent non-tumor mammary cells and was correlated with estrogen receptor, progesterone receptor, nuclear-associated antigen Ki-67 and tumor protein p53 status, as well as breast cancer subtypes. Furthermore, low SIRT4 expression was associated with poor overall survival in breast cancers patients, particularly in Luminal A patients. Univariate and multivariate analyses confirmed that increased SIRT4 expression was an independent predictive factor of good prognosis for breast cancer patients. In conclusion, SIRT4 expression represents a significant favorable prognostic factor for patients with invasive breast cancer. PMID- 27698835 TI - Cerebellar hemangioblastoma mimicking an aneurysm: A case report and literature review. AB - Hemangioblastomas (HBMs) are highly vascular tumors of the central nervous system. Sporadic HBMs are nearly always solitary, and solitary HBMs are similar to intracranial arteriovenous malformations due to their highly vascular characteristics. However, to the best of our knowledge, cases of HBM in the cerebellum mimicking an aneurysm have never been reported in the literature. The present study reports a case of an HBM on the right cerebellar hemisphere mimicking an aneurysm, which originated from the right posterior inferior cerebellar artery, as determined using magnetic resonance angiography and digital subtraction angiography. The patient was admitted the Department of Neurosurgery at the Tsinghua University Yuquan Hospital (Beijing, China) in January 2015 due to a 4-year history of intermittent headaches. The diagnosis of an HBM was determined during surgery and the tumor was totally resected by changing the operation technique, with no complications. In conclusion, it is difficult to distinguish between HBMs and intracranial vascular diseases, particularly aneurysms. Surgeons should consider the possibility carefully prior to surgery and careful prepare for each eventuality. PMID- 27698837 TI - BCAT1 promotes tumor cell migration and invasion in hepatocellular carcinoma. AB - Branched-chain amino acid transaminase 1 (BCAT1) has been associated with numerous types of tumors; however, few previous studies have evaluated the expression and role of BCAT1 in hepatocellular carcinoma (HCC). In the present study, the expression of BCAT1 was detected by reverse transcription-quantitative polymerase chain reaction and immunoblotting in six HCC cell lines and 74 pairs of HCC and adjacent non-cancerous liver tissues. In addition, the correlation between the expression levels of c-Myc and BCAT1 was analyzed using immunohistochemistry. Furthermore, RNA silencing was performed using c-Myc specific or BCAT1-specific small interfering RNA, after which wound healing and Transwell cell invasion assays were performed. Finally, the clinicopathological characteristics of BCAT1 in patients with HCC were analyzed. It was shown that the expression of BCAT1 was significantly higher in HCC tissues compared with adjacent non-tumor tissues (P<0.001), and in HCC cell lines compared within the L 02 hepatic cell line (P<0.001). In addition, immunohistochemical analyses indicated that the expression of BCAT1 was positively correlated with c-Myc (r=0.706, P<0.001). BCAT1 expression was shown to be downregulated in c-Myc knockdown cells, and silencing of BCAT1 expression reduced the invasion and migration of HCC cells. Furthermore, a clinical analysis indicated that BCAT1 expression in HCC tissues was significantly associated with the tumor-node metastasis stage, tumor number and tumor differentiation (all P<0.05), and that BCAT1 was able to predict the 5-year survival and disease-free survival rates of patients with HCC (both P<0.001). The results of the present study suggested that BCAT1 expression is upregulated in patients with HCC, and that BCAT1 may serve as a potential molecular target for the diagnosis and treatment of HCC. PMID- 27698836 TI - Co-evolution of tumor-associated macrophages and tumor neo-vessels during cervical cancer invasion. AB - Considering the crucial significance of the tumor microenvironment in cancer development and progression, the present study aimed to investigate the changes in macrophages and angiogenesis during the cervical cancer (CC) progression process from chronic cervicitis to cervical intraepithelial neoplasia grades I III (CIN I-III) to CC. This investigation included quantitative analysis and assessment of the spatial associations between tumor-associated macrophages (TAMs) and tumor neo-vessels. The conventional immunohistochemistry staining technique was used to detect cluster of differentiation (CD)68 and CD105 biomarker expression for TAMs and tumor neo-vessels, respectively. In addition, with the assistance of quantum dot (QD)-based two-component in situ imaging technology, the expression of the TAMs and tumor neo-vessels could be observed simultaneously. The quantitative analysis and co-evolution of the TAMs and tumor neo-vessels could then be processed. During the progression process from chronic cervicitis to cervical CIN I-III, and ultimately to invasive CC, the expression of the macrophages and neo-vessels in the tumor microenvironment increased synchronously. According to the quantitative analysis results, the median value of the TAM density was higher in the CC group (5,540.14) than in the CIN I-III group (2,502.17) and the chronic cervicitis group (1,403.31), with statistical significance in all three groups (P<0.001, for between-group comparisons). The number of neo-vessels was also much higher in the CC group (n=27) than in the CIN I-III group (n=17) or the chronic cervicitis group (n=6.5), with statistical significance in all three groups (P<0.001, for between-group comparisons). These findings demonstrated the great significance and close association of TAMs and tumor angiogenesis during CC development and progression. Thus, QDs-based in situ and simultaneous imaging of key cancer molecules may provide insights with regard to the biology of cancer invasion. PMID- 27698838 TI - Genetic analysis and clinical investigation of a pedigree with multiple endocrine neoplasia type 2A: A case report. AB - Multiple endocrine neoplasia 2A (MEN2A) is characterized by the coexistence of tumors that involve two or more endocrine glands within the same patient, and is defined as the occurrence of medullary thyroid carcinoma in association with pheochromocytoma (PHEO) and parathyroid tumors or hyperparathyroidism. The pathogenesis of MEN2A is due to the mutation of a tyrosine kinase receptor that is encoded by the rearrangement during transfection (RET) proto-oncogene. The mutation often occurs in exon 10q11.2. The present study reports the case of a 73 year-old man with severe hypercalcemia, bilateral adrenal PHEO and a thyroid nodule. A genetic panel was obtained, and the RET mutation was indicated. The pedigree of the patient was also studied. Genetic testing of the patient's son indicated heterozygosity for the same mutation at codon 634. The first symptom of the two patients was PHEO, which is uncommon. In addition, varied phenotypes were identified in the two patients. In the present study, the association between the phenotypic variation of the RET gene and the occurrence of MEN2A is discussed. PMID- 27698839 TI - Perioperative stroke in a patient undergoing surgery for oral cancer: A case report. AB - Carotid artery stenosis is a significant risk factor for stroke. In elderly patients with carotid atherosclerosis and stenosis, it is not unusual for oral, head and neck cancer surgery to be performed. The present study describes a case of stroke that occurred during a neck dissection for the treatment of cervical lymph node metastasis of a left maxillary gingival carcinoma. The patient was an 84-year-old female who was considered to be at high risk of a stroke based on pre operative head and neck computed tomography scans, which detected severe carotid atherosclerosis and stenosis. There was no possible stroke prophylaxis available during the performance of the neck dissection in the present case. However, if patients are evaluated to be high-risk pre-operatively, statin agents should be administered, the surgery should be carefully performed, adequate sedation should be maintained post-operatively and the patient should be followed up, aiming to achieve the early detection of a possible stroke. PMID- 27698840 TI - Association between FOXM1 and hedgehog signaling pathway in human cervical carcinoma by tissue microarray analysis. AB - Forkhead box M1 (FOXM1) and hedgehog (Hh) signaling pathway are implicated in the formation and development of human tumors, including cervical cancer. Previous studies have indicated that FOXM1 may be a downstream target gene of the Hh signaling pathway, but their association in cervical cancer is largely unknown. In the present study, the expression of FOXM1 and Hh signaling molecules was evaluated by immunohistochemical analysis in a tissue microarray that contained 70 cervical cancer tissues and 10 normal cervical tissues. In addition, the association of these molecules with clinicopathological parameters, and the association between FOXM1 and various molecules involved in the Hh signaling pathway was investigated. The results indicated that FOXM1 and Hh signaling molecules were overexpressed in cervical cancer tissues. The protein expression levels of FOXM1, glioma-associated oncogene 1 (GLI1) and smoothened (SMO) correlated with the clinical stage of the tumors, while the protein expression levels of Sonic Hh (SHh), patched 1 (PTCH1) and GLI1 correlated with the pathological grade of the tumors. The expression levels of GLI1 were lower in tissues without lymph node metastasis than in tissues with lymph node metastasis. In addition, FOXM1 expression correlated with GLI1, SHh and PTCH1 expression in cancer tissues. These findings confirmed the participation of FOXM1 and the Hh signaling pathway in cervical cancer. Furthermore, the finding that FOXM1 may be a downstream target gene of the Hh signaling pathway in cervical cancer provides a potential novel diagnostic and therapeutic target for cervical cancer. PMID- 27698842 TI - Tazarotene-induced gene 2 is associated with poor survival in non-small cell lung cancer. AB - The aim of the present study was to investigate the expression of tazarotene induced gene 2 (TIG2) and evaluate the clinicopathological variables and prognostic value for non-small cell lung cancer (NSCLC) patients. Reverse transcription-polymerase chain reaction and western blotting were utilized to detect TIG2 expression in NSCLC specimens and adjacent noncancerous tissue. Furthermore, the present study investigated the protein expression and the clinicopathological significance of TIG2 in 98 paraffin-embedded NSCLC samples by using immunohistochemistry. The results of the present study demonstrated that the expression of TIG2 mRNA (P=0.003) and protein (P=0.0024) was significantly reduced in NSCLC compared with corresponding noncancerous tissue. TIG2 protein expression in NSCLC was significantly associated with lymph node metastasis (P=0.006), Tumor-Node-Metastasis stage (P=0.021) and degree of differentiation (P=0.025). The Kaplan-Meier method and log-rank test revealed that high TIG2 expression was significantly associated with increased survival of NSCLC patients (P=0.003). Multivariate analysis revealed that TIG2 expression was an independent prognostic factor of the overall survival of NSCLC patients. Decreased expression of TIG2 may be useful as a biomarker for poor prognosis in NSCLC carcinogenesis and may act as a target for gene therapy for the treatment of NSCLC patients. PMID- 27698841 TI - SPAG9 is overexpressed in osteosarcoma, and regulates cell proliferation and invasion through regulation of JunD. AB - Sperm-associated antigen 9 (SPAG9) is a recently characterized oncoprotein that is considered to be involved in several forms of malignant tumor. However, its biological function and expression pattern in human osteosarcoma have not yet been elucidated. In the present study, SPAG9 expression was analyzed in 58 cases of human osteosarcoma by immunohistochemistry. The results demonstrated that SPAG9 was overexpressed in 63.8% (37/58) of osteosarcoma tissues, while normal bone tissues exhibited negative SPAG9 expression. SPAG9 small interfering RNA was employed in the U2OS cell line, which has high endogenous expression, and SPAG9 transfection was performed in the MG63 cell line, which has low endogenous expression. MTT and Matrigel invasion assays demonstrated that SPAG-9-knockdown significantly reduced U2OS cell invasion and proliferation, while SPAG9 transfection enhanced MG63 cell proliferation and invasion. Furthermore, it was observed that SPAG9 positively regulated cyclin D1, phosphorylated-c-Jun NH2 terminal kinase (JNK) and JunD expression. Treatment with the JNK inhibitor, SP600125, abolished the upregulatory effect of SPAG9 on JunD. Taken together, the present study identified SPAG9 as a critical oncoprotein involved in osteosarcoma proliferation and invasion, possibly functioning through JNK-JunD signaling. PMID- 27698843 TI - Functional redundancy of the Notch pathway in ovarian cancer cell lines. AB - Epithelial ovarian cancer is the most lethal gynecologic malignancy, despite advances in treatment. The most common histological type, high-grade ovarian serous carcinoma (OSC) is usually diagnosed at an advanced stage, and although these types of tumors frequently respond to surgery and platinum-based chemotherapy, they usually recur. Ovarian clear cell carcinoma (OCCC) is an unusual histological type, which is known to be intrinsically chemoresistant and is associated with poor prognosis in advanced stages. In recent years, genetic alterations and epigenetic modulation of signaling pathways have been reported in OSC and OCCC, including the overexpression of Notch pathway elements and histone deacetylases. Histone deacetylase inhibitors (HDACis), including vorinostat (suberoylanilide hydroxamic acid), alter the transcription of genes involved in cell growth, survival and apoptosis, and have become an attractive therapeutic approach. However, no previous work has addressed the effect of HDACis, and in particular vorinostat, on Notch signaling in ovarian cancer. Therefore, the present study aimed to investigate the modulation of the Notch pathway by vorinostat in ovarian cancer. Using immunofluorescence and quantitative polymerase chain reaction, the present results revealed that vorinostat activated the Notch pathway in OCCC and OSC cell lines, through different Notch ligands. In OCCC, the activation of the Notch pathway appeared to occur through Delta-like (Dll) ligands 1, 2 and 3, whereas in OSC Dll1 and Jagged 1 and 2 ligands were involved. The activation of the Notch pathway by vorinostat, in OCCC and OSC cell lines, culminated in the increased expression of the same downstream transcription factors, hairy enhancer of split (Hes) 1 and 5, and Hes-related proteins 1 and 2. In conclusion, vorinostat modulates the expression of several downstream targets of the Notch pathway and independent Notch receptors and ligands that are expressed in OSC and OCCC. This upregulation of the Notch pathway may explain why vorinostat therapy fails in ovarian carcinoma treatment, as shown in certain clinical trials. PMID- 27698844 TI - Primitive neuroectodermal tumor originating from the lung: A case report. AB - Primitive neuroectodermal tumors (PNETs) are small, round cell tumors that may be classified as peripheral or central, based on their site of origin. PNETs often arise in the soft tissue or bone of young adults. Although not common, PNETs have been described in other organs, including the gonads, kidneys, myocardium and pancreas, but rarely in the lungs without chest wall or pleural involvement. The present study reports a rare case of peripheral PNET (pPNET), which originated in the lung. A 37-year-old female patient presented at Xuzhou Central Hospital (Xuzhou, China) with a history of a dry cough, mild dyspnea and slight pain in the left chest. Histopathological and immunohistochemical analyses permitted the diagnosis of a pPNET. The patient was treated with surgical resection, followed by chemotherapy (including cyclophosphamide, cisplatin and vincristine), radiotherapy and traditional Chinese medicine (including Kanglaite and Shenqi Fuzheng injections). At the time of writing, the patient was alive with no sign of recurrence and under regular follow-ups at the Outpatient Clinic of Xuzhou Central Hospital. PMID- 27698845 TI - Multidisciplinary collaboration in gallbladder carcinoma treatment: A case report and literature review. AB - Gallbladder carcinoma (GBC) is a rare and highly aggressive disease. The diagnosis of this cancer is difficult due to its occult onset. Hence, GBC is often detected late and at an advanced stage. Although physicians and researchers are continually working to improve the treatment for advanced-stage disease, GBC is usually associated with short survival times. The present study describes a case of GBC that was first diagnosed with accompanying cholecystolithiasis at the time of cholecystectomy. Cancer relapse occurred 1.5 years after the cholecystectomy. Multidisciplinary collaboration was involved in the decision making process for the treatment of this aggressive recurrence, and the survival time was successfully extended to 26 months. Importantly, high-grade intraepithelial neoplasia and positive margins had previously been detected post cholecystectomy at a different institution, but were ignored. Relapse may have been preventable had the cancer been diagnosed when it was initially observed. Taken together, these findings suggest that multidisciplinary collaboration should be considered for the management of advanced GBC, whereby patients will benefit from improved survival times. Furthermore, it is recommended that samples obtained from patients undergoing cholecystectomy should more carefully analyzed for evidence of cancerous or precancerous tissues. PMID- 27698846 TI - Expression of early growth response gene-1 in precancerous lesions of gastric cancer. AB - Several studies have demonstrated a correlation between the expression of early growth response gene-1 (EGR-1) and the progression of gastric cancers at advanced stages. However, the effects of EGR-1 expression on human gastric cancer progression, particularly on precancerous lesions, have not been investigated. In this study, we evaluate EGR-1 expression levels in target mucosa from patients with early gastric cancer and precancerous lesions, and assess whether EGR-1 expression affects the oncogenic phenotypes of human gastric cancer cells. EGR-1 protein levels were measured in tissues from subjects with normal mucosa (n=6), low-grade dysplasia (n=6), high-grade dysplasia (n=4) and adenocarcinoma (n=3) using enzyme-linked immunosorbent assay and immunohistochemistry analyses. We also investigated the role of EGR-1 in tumor cell behavior by transiently expressing a dominant active EGR-1 variant in cultured cells. A positive correlation was observed between EGR-1 expression and gastric carcinogenesis (P=0.016). Furthermore, there was an increase in nuclear and cytoplasmic expression of EGR-1 in accordance with the histological grade (P for trends=0.003 and 0.003, respectively), and a positive association between the sum of the nuclear and cytoplasmic EGR-1 expression values and the histological grade (P=0.003). In addition, transient overexpression of EGR-1 enhanced cell proliferation, stimulated cell migration, and promoted the phosphorylation of p38 MAPK and AKT in gastric cancer cells in vitro. Our findings demonstrate that EGR 1 may contribute to the early stages of gastric carcinogenesis via the alteration of tumor cell behaviors. PMID- 27698847 TI - Paraneoplastic Morvan's syndrome following surgical treatment of recurrent thymoma: A case report. AB - Morvan's syndrome (MoS) is a rare, complex neurological disorder characterized by neuromyotonia, neuropsychiatric features, dysautonomia and neuropathic pain. The majority of MoS cases have a paraneoplastic aetiology, usually occurring prior to the diagnosis of the underlying tumour and showing improvement following its treatment. The present study reports the case of a 35-year-old Caucasian male patient who was diagnosed with stage IVA thymoma. Thymectomy, lung resection, diaphragmatic pleurectomy and pericardio-phrenectomy were performed 6 months after neoadjuvant chemotherapy. The pathological evaluation revealed a type B2-B3 thymoma with focal squamous differentiation. Two years later, the patient underwent new surgical treatment for a local recurrence of the same histological type, and 4 weeks later, the patient presented with complex neurological symptoms compatible with MoS, including neuromyotonia, neuropsychiatric features, dysautonomia and neuropathic pain. Electromyography was compatible with a diagnosis of neuromyotonia. Brain magnetic resonance imaging scan and tests for serum anti-acetylcholine receptor, anti-striated muscle antibodies and anti-30 kDa titin fragment antibodies were all negative, whereas tests for anti-voltage gated potassium channel (VGKC)-complex antibodies (333.3 pmol/l), anti-leucine rich glioma inactivated protein 1 and anti-contactin-associated protein-like 2 antibodies were positive. The patient underwent 3 cycles of intravenous administration of immunoglobulins (0.4 g/kg/day for 5 days every 4 weeks) with little clinical and electrophysiological improvement. We speculated that the late onset of the symptoms in the present patient may have been triggered by an increase in the serum level of anti-VGKC antibody, which was caused by the surgery performed for the treatment of recurrent thymoma. To the best of our knowledge, the present report is the first case of MoS associated with this histological type of thymoma uncommonly occurring upon surgical treatment of recurrent thymoma. PMID- 27698848 TI - Clinicopathological analysis of CD44 and CD24 expression in invasive breast cancer. AB - A subpopulation of breast cancer cells with cluster of differentiation (CD)44 positive and CD24-negative expression has been reported to have stem cell properties and to have a higher tumorigenic capacity than other cells. However, the clinicopathological characteristics of this subpopulation are not fully understood. In this study, we aimed to identify the correlations between the expression of CD44 and CD24 and clinicopathological parameters and overall survival. We studied specimens from 262 patients with invasive breast cancer. Immunohistochemical staining for CD44 and CD24 was performed using tissue microarrays. The clinicopathological factors were evaluated from the patients' medical records. In correlation analysis, CD44 expression was significantly associated with human epidermal growth factor receptor 2 (HER2)-negative status (P<0.001). Conversely, CD24 expression was significantly associated with HER2 positive status (P<0.001). CD44 and CD24 expression did not demonstrate any correlation with the age, tumor size, axillary lymph node metastasis status, tumor stage, histological grade, estrogen receptor status and progesterone receptor status of patients. Upon survival analysis, there was no statistical difference in overall survival according to the expression of CD44 and CD24. The results from this study suggest that CD44 and CD24 are clinically significant markers associated with breast tumorigenesis, but not sufficient factors in determining the prognosis of invasive breast cancer. PMID- 27698849 TI - Fluorescence in situ hybridization testing of chromosomes 6, 8, 9 and 11 in melanocytic tumors is difficult to automate and reveals tumor heterogeneity in melanomas. AB - Malignant melanomas may be difficult to differentiate from benign nevi on the basis of histology. Contrary to nevi, the majority of melanomas harbor chromosomal imbalances. Comparative genomic hybridization-based and fluorescence in situ hybridization (FISH) tests can help differentiating malignant from benign tumors. In the present study, eight-bacterial artificial chromosome (BAC) probes targeting chromosomes 6, 8, 9 and 11 were tested by FISH, and compared with a commercial four-color FISH probe set targeting chromosomes 6 and 11 in a first set of 62 tissue microarray-included melanocytic tumors (47 melanomas and 15 nevi). A second set of 108 tumors (70 melanomas and 38 nevi) was analyzed with the eight-probes kit, and manual counting was compared with the newly developed automated FISH signals counting and with semi-quantitative visual detection of chromosomal imbalances. Intra-tumor heterogeneity was also evaluated in 12 melanomas and 10 patients with paired melanoma samples. Testing the tumors from the first set with the commercial kit and the eight-probes test permitted to correctly identify 45/47 and 47/47 melanomas, respectively. In the second tumor set, 65/70 malignant tumors presented at least one chromosomal imbalance, whereas none was detected in the nevi. The agreement between manual and automated signals counting was better in good-quality FISH slides compared with poor-quality slides. Semi-quantitative visual appreciation of chromosomal imbalances also reached strong agreement with exact manual counting. In addition, a frequent cytogenetic heterogeneity within melanomas and between paired tumors was noticed in patients with metastatic melanomas. To conclude, FISH testing targeting chromosomes 6, 8, 9 and 11 enabled to differentiate the majority of melanomas from nevi but was difficult to automate. Tumor cytogenetic heterogeneity was frequent and could impair FISH testing. PMID- 27698850 TI - Killian-Jamieson diverticulum mimicking a calcified thyroid nodule on ultrasonography: A case report and literature review. AB - As a rare hypopharyngeal diverticulum, Killian-Jamieson diverticulum (KJD) is usually incidentally detected, small, asymptomatic and likely to be misdiagnosed as a thyroid nodule. In order to avoid unnecessary treatments resulting from misdiagnosis, principles to distinguish between esophageal diverticula and thyroid nodules should be noted clearly. The current study presents a case of an asymptomatic unilateral KJD that mimicked a calcified thyroid nodule. In the current case, a 40-year-old man presented with a 'suspected malignant thyroid nodule' in the left thyroid gland, and underwent left thyroid lobectomy and a neck exploration. However, no visible 'suspected tumor', but a sac protruding from the left anterolateral wall of the cervical esophagus, was observed during the surgery. A swallow test on ultrasonography (US) in combination with pharyngoesophagography was then performed, which confirmed the diagnosis. The patient recovered well during the 3-month follow-up after the operation. The present study indicates that real-time US and pharyngoesophagography are important techniques to distinguish a KJD from a thyroid nodule so that unnecessary surgical intervention can be avoided.

AB - Genetic mutations on signaling pathways are found in patients with T-cell acute lymphoblastic leukemia (T-ALL) and act as markers of high-risk leukemia. Mutations in dynamin 2 (DNM2) have been reported in T-ALL, particularly in early T-cell precursor-ALL. In the present study, DNM2 mutations were screened by sequencing DNM2 exons obtained by polymerase chain reaction amplification and gel purification in adult T-ALL patients. A total of 4 novel DNM2 mutations were identified in adult T-ALL patients, with a mutation rate of 9.5%, and the DNM2 mutations were found to co-exist with NOTCH1 and PHD finger protein 6, and were also associated with high-risk leukemia. A high rate of silent mutation was also found in the patients, but no significant association was found between the silent mutations and patients' clinical features. The present findings suggested the DNM2 mutations may be involved in the oncogenesis of T-ALL. PMID- 27698852 TI - ABCG2 expression in colorectal adenocarcinomas may predict resistance to irinotecan. AB - Irinotecan is a key drug for patients with advanced and recurrent colorectal carcinoma. However, the efficacy of irinotecan is not sufficient; partly, as there is no useful marker to predict chemosensitivity to the drug. The aim of the present study was to evaluate whether the expression levels of adenosine triphosphate-binding cassette sub-family G (WHITE) member 2 (Junior blood group) (ABCG2) in primary colorectal tumors predict chemoresistance to irinotecan. Using the resected primary tumor specimens of 189 patients with colorectal cancer, the association between the immunohistochemical expression of ABCG2 protein and the results of the collagen gel droplet embedded culture drug sensitivity test, performed to evaluate the chemosensitivity to SN-38 (an active metabolite of irinotecan), was investigated. Among the 189 patients, 17 received irinotecan based chemotherapy, and their responses and progression-free survival (PFS) were analyzed. The tumors of patients with increased ABCG2 expression accounted for 60% of the tumors examined, and were significantly more resistant to SN-38, compared with patients with low ABCG2 expression (P<0.001). In a multivariate logistic regression analysis, increased expression of ABCG2 protein was an independent and significant predictor of resistance to SN-38, increasing the risk of resistance by 12-fold. Increased expression of ABCG2 and a low sensitivity to SN-38 was significantly associated with resistance to irinotecan-based chemotherapy (P=0.01 and 0.028, respectively). The median PFS of patients with increased expression of ABCG2 was significantly shorter, compared with patients with low expression levels of ABCG2 (104 vs. 242 days; P=0.047). The increased immunohistochemical expression of ABCG2 in primary tumors may be a useful predictive biomarker of resistance to irinotecan-based chemotherapy for patients with recurrent or metastatic colorectal cancer. PMID- 27698853 TI - Deguelin inhibits proliferation and migration of human pancreatic cancer cells in vitro targeting hedgehog pathway. AB - Pancreatic cancer (PC) is a highly lethal malignancy with few effective therapies. Deguelin, a natural compound of the flavonoid family of products, has been reported to have an inhibitory effect on various cancers. In the present study, we investigated whether deguelin had antitumor efficacy in PC. Deguelin treatment was observed to inhibit growth and induce apoptosis in two PC cell lines (Bxpc-3 and Panc-1). In addition, it inhibited migration and invasion in these two cell lines. The activation of the hedgehog (Hh) signaling pathway, as well as matrix metalloproteinases (MMP)-2 and MMP-9, was suppressed by deguelin. These results suggest that deguelin may be a potential chemotherapeutic agent for PC, possibly through the suppression of the Hh signaling pathway. PMID- 27698854 TI - Misdiagnosed infantile rhabdomyofibrosarcoma: A case report. AB - Infantile rhabdomyofibrosarcoma is a rare form of soft-tissue tumor often associated with difficulties in diagnosis. The disease is positioned intermediately between rhabdomyosarcoma and infantile fibrosarcoma in terms of clinical presentation, immunohistochemistry, behavior, morphology and ultrastructural features. Reports of rhabdomyofibrosarcoma cases are limited in the literature. The present case describes a 26-month-old female who presented with a slowly progressive, soft-tissue mass in the right chest wall. The mass was successfully treated with surgery. Using histopathology, the tumor was diagnosed and classified as infantile rhabdomyofibrosarcoma. The patient has been followed up for 2 years and is currently in good condition. The present case demonstrates that early, radical, local surgery and multidisciplinary cooperation were successful for the treatment of rhabdomyofibrosarcoma, and close follow-up highly recommended. PMID- 27698855 TI - Aneurysmal bone cyst of the metatarsal: A case report. AB - An aneurysmal bone cyst (ABC) is a rare, non-neoplastic, destructive, hemorrhagic and expansile lesion accounting for 1% of all bone tumors. This type of lesion predominantly affects long bones and vertebrae. ABC of the metatarsal is rare and only a few cases have been reported in the literature to date. The present study reports a rare case of ABC of the third metatarsal occurring in a 27-year-old male patient, who presented with repeated foot swelling that had lasted for ~1 year. Other clinical manifestations included limping, multiple lumps (defined as masses on or below the skin, as detected by imageological diagnosis) and progressively increasing local pain in his right foot. Magnetic resonance imaging of the right metatarsal revealed a segmented, expansile, multiseptated lesion with fluid-fluid levels. An en bloc resection was performed and the defect was replaced with a tricortical iliac autograft. Pathological analysis of the resected tissue suggested ABC. The present study aims to describe a case of ABC of the metatarsal, a condition that often poses a diagnostic challenge, and to underline the importance of radiological and histological examinations for the accuracy of that diagnosis. PMID- 27698856 TI - Primary gastrointestinal stromal tumor of the liver: A case report and review of the literature. AB - Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors located in the alimentary tract. A small portion of GISTs are observed in extra gastrointestinal regions, primarily in the omentum, mesentery and retroperioneum, and these types of GISTs are referred to as extra-gastrointestinal stromal tumors. The present study reports of a patient with unique primary liver GIST. The patient underwent en bloc resection and post-operative administration of imatinib, and subsequently experienced a good prognosis. The present case is followed by a brief review of reported cases of liver GISTs identified in the literature. The literature revealed that primary liver GISTs are usually large in size and possess a high mitotic index, which contributes to malignant characterization, thus classifying these tumors as high-risk. En bloc resection remains the mainstay of treatment for resectable primary liver GISTs. However, the prognosis of these patients is not favorable. Perioperative administration of imatinib may be useful to a certain extent, and interventional therapy, including radiofrequency ablation, should be considered. PMID- 27698857 TI - Immunohistochemical patterns in the differential diagnosis of rhinopharyngeal granulocytic sarcoma. AB - Granulocytic sarcoma (GS) is a rare extramedullary manifestation of acute myeloid leukemia (AML). GS may develop simultaneously to AML or as a relapse of leukemia, particularly following allogeneic hematopoietic stem cell transplant. Subperiosteal bone, lymph nodes and skin are commonly involved, whereas rhinopharyngeal involvement is less common, with only 14 cases reported in the literature. Due to its rarity, rhinopharyngeal GS may lead to diagnostic pitfalls, particularly when it is poorly differentiated or is without concomitant marrow involvement. Thus, immunohistochemical findings play a key role in diagnosis. The current report describes a case of a 53-year-old female suffering from rhinopharyngeal GS and with a history of AML treated with chemotherapy and radiotherapy, focusing on the importance of the immunohistochemical pattern to assess the right diagnosis. Recent studies have demonstrated that the immunophenotype is of utmost importance for the diagnosis of GS. The high expression of myeloperoxidase (MPO) is common in GS; however, ~30% of GSs do not contain MPO. Therefore, the presence of other markers is required to confirm the diagnosis of GS. PMID- 27698859 TI - Iodine-125 irradiation inhibits invasion of gastric cancer cells by reactivating microRNA-181c expression. AB - Iodine-125 (125I) seed implantation has been widely used for the treatment of unresectable advanced tumors. However, the molecular mechanisms underlying the tumor-suppressive effects of 125I irradiation have not been fully elucidated. The present study demonstrated that 125I irradiation suppresses cell viability and inhibits cell invasiveness of gastric cancer KATO-III and MKN45 cells. Further mechanistic analysis suggested the involvement of microRNA (miR)-181c in the inhibitory effects induced by 125I irradiation. Methylated DNA immunoprecipitation coupled with quantitative-polymerase chain reaction demonstrated that treatment with 125I irradiation, at the dose of 4 Gy, induced promoter demethylation of the miR-181c gene in KATO-III and MKN45 cells. Following irradiation, the expression of miR-181c was significantly increased, which may be attributed to the demethylation caused by 125I irradiation. In addition, upregulation of miR-181c by administration of miR-181c mimics decreased cell invasion, suggesting the role of miR-181c as a tumor suppressor. More importantly, the tumor-suppressive effects of 125I irradiation were significantly compromised by the introduction of miR-181c inhibitors. Overall, these results reveal that 125I irradiation inhibits invasiveness of gastric cancer cells by reactivating miR-181c at the epigenetic level, thereby providing important molecular evidence for the anticancer effects of 125I irradiation. PMID- 27698860 TI - Leucine zipper, down regulated in cancer-1 gene expression in prostate cancer. AB - Numerous genetic alterations have been implicated in the development of prostate cancer (PCa). DNA and protein microarrays have enabled the identification of genes associated with apoptosis, which is important in PCa development. Despite the molecular mechanisms are not entirely understood, inhibition of apoptosis is a critical pathophysiological factor that contributes to the onset and progression of PCa. Leucine zipper, down-regulated in cancer 1 (LDOC-1) is a known regulator of the nuclear factor (NF)-mediated pathway of apoptosis through the inhibition of NF-kappaB. The present study investigated the expression of the LDOC-1 gene in LNCaP, PC-3, PNT1A and PNT2 prostate cell lines by reverse transcription-quantitative polymerase chain reaction. In addition LDOC-1 protein expression in normal prostate tissues and PCa was studied by immunohistochemistry. LDOC-1 messenger RNA resulted overexpressed in LNCaP and PC 3 PCa cell lines compared with the two normal prostate cell lines PNT1A and PNT2. The results of immunohistochemistry demonstrated a positive cytoplasmic LDOC-1 staining in all PCa and normal prostate samples, whereas no nuclear staining was observed in any sample. Furthermore, a more intense signal was evidenced in PCa samples. LDOC-1 gene overexpression in PCa suggests an activity of LDOC-1 in PCa cell lines. PMID- 27698861 TI - IgM multiple myeloma with an extremely rare non-aggressive presentation: A case report. AB - In the present study, the case of a 41-year-old man with immunoglobulin (Ig)M multiple myeloma (MM) that presented with an unusually non-aggressive clinical course who has survived for >9 years to date, is presented. Initial diagnosis of symptomatic MM was established according to the International Myeloma Working Group consensus statement and guidelines. Due to the mild symptoms, no therapy was administered and the patient was closely followed up. Eight years after initial diagnosis, clinical, morphological and genetic progression occurred with the development of hypercalcemia, progressively deteriorating polyneuropathy, clonal expansion of plasma cells up to 50% of hematopoietic cells and demonstration of the typical t(11;14) translocation (Ig heavy chain locus rearrangement). Subsequently, 4 cycles of induction chemotherapy with velcade, cyclophosphamide and dexamethasone, were administered. At the time of writing, the patient remained alive in generally good health. To the best of our knowledge, with a survival time of >9 years, this case reports the longest survival time of an IgM MM patient to date, which contradicts previous evidence that suggests IgM MM exhibits an aggressive clinical course. PMID- 27698858 TI - Differential expression of viral agents in lymphoma tissues of patients with ABC diffuse large B-cell lymphoma from high and low endemic infectious disease regions. AB - Diffuse large B-cell lymphoma (DLBCL), the most common type of non-Hodgkin's lymphoma (NHL) in adults, accounts for approximately 30-40% of newly diagnosed lymphomas worldwide. Environmental factors, such as viruses and bacteria, may contribute to cancer development through chronic inflammation and the integration of oncogenes, and have previously been indicated in cervical cancer, hepatocellular carcinoma, gastric cancer and lymphoproliferative disorders. In the present study, the presence of microbial agents was analyzed in the lymphoma tissue of patients with activated B-cell like (ABC) DLBCL. The present study compared two groups of patients from geographically varied regions that possess a difference in the prevalence of viral and other microbial agents. The patient populations were from Sweden (a low endemic infectious disease region) and Egypt (a high endemic infectious disease region). A differential expression of several viruses in lymphoma tissues was noted when comparing Swedish and Egyptian patients. JC polyomavirus (JCV) was detected in Swedish and Egyptian patients and, uniquely, the complete hepatitis B virus (HBV) genome was detected only in Egyptian lymphoma patients. None of these viruses were detected in control lymph tissues from Sweden or Egypt. In total, 38% of the Egyptian patients were found to have HBV surface antigens (HBsAgs) in their serum; however, HBsAgs were not found in any of the Swedish patients. The percentage of serum HBsAgs in Egyptian patients with ABC DLBCL was significantly increased compared with the general Egyptian population (P<0.05). The present study may support a notion that viral agents, including JCV and HBV, may be involved in the tumorigenesis of DLBCL in regions of high infectious disease. PMID- 27698862 TI - Aspirin may inhibit angiogenesis and induce autophagy by inhibiting mTOR signaling pathway in murine hepatocarcinoma and sarcoma models. AB - Aspirin is known to have inhibitory effects on growth development in various types of tumor. In previous studies, it was observed to inhibit angiogenesis by downregulating the expression of vascular endothelial growth factor-A (VEGF-A). In the present study, murine H22 hepatocarcinoma and S180 sarcoma models were used to ascertain whether aspirin could inhibit angiogenesis and promote autophagy in tumors. Tumor-bearing mice were randomly divided into four groups with 10 mice per group: i) no treatment; ii) low-dose aspirin (100 mg/kg); iii) high-dose aspirin (400 mg/kg); iv) everolimus group (4 mg/kg). The effects of high-dose aspirin were validated through preliminary experiments. The drug treatment was administered every day for 14 days. The tumor size was measured every other day and then the tumor growth curve was plotted, and the tumor inhibitory rates were calculated. The expression levels of phosphorylated mammalian target of rapamycin (p-mTOR), hypoxia-inducible factor-1alpha (HIF 1alpha), VEGF-A, UNC-51-like kinase-1 (ULK1) and microtubule-associated protein 1 light chain 3A (LC3A) were detected by immunohistochemistry and western blot analysis, respectively. We observed that tumor growth delay was achieved in both H22 hepatocarcinoma and S180 sarcoma models following treatment with aspirin. The tumor growth inhibition rates induced by low and high-dose aspirin and everolimus were 19.6, 33.6 and 53.7% (P<0.05) in H22 hepatocarcinoma, and 25.7, 40.6 and 48.7% (P<0.05) in S180 sarcoma. The immunohistochemistry and western blot analysis data from the models revealed that the expression of p-mTOR, HIF-1alpha and VEGF-A was decreased, while the expression of ULK1 and LC3A was increased following treatment with aspirin and everolimus. The changes were more apparent in the high-dose aspirin and everolimus groups (P<0.01). The inhibitory action of aspirin and everolimus on tumor angiogenesis may be through inhibiting the expression of p-mTOR, HIF-1alpha and VEGF-A. Alternatively, aspirin may induce autophagy by inhibiting the mTOR signaling target and then increasing ULK1 and LC3A. PMID- 27698863 TI - Promoter methylation and downregulated expression of the TBX15 gene in ovarian carcinoma. AB - TBX15 is a gene involved in the development of mesodermal derivatives. As the ovaries and the female reproductive system are of mesodermal origin, the aim of the present study was to determine the methylation status of the TBX15 gene promoter and the expression levels of TBX15 in ovarian carcinoma, which is the most lethal and aggressive type of gynecological tumor, in order to determine the role of TBX15 in the pathogenesis of ovarian carcinoma. This alteration could be used to predict tumor development, progression, recurrence and therapeutic effects. The study was conducted on 80 epithelial ovarian carcinoma and 17 control cases (normal ovarian and tubal tissues). TBX15 promoter methylation was first determined by pyrosequencing following bisulfite modification, then by cloning and sequencing, in order to obtain information about the epigenetic haplotype. Immunohistochemical analysis was performed to evaluate the correlation between the methylation and protein expression levels. Data revealed a statistically significant increase of the TBX15 promoter region methylation in 82% of the tumor samples and in various histological subtypes. Immunohistochemistry showed an inverse correlation between methylation levels and the expression of the TBX15 protein. Furthermore, numerous tumor samples displayed varying degrees of intratumor heterogeneity. Thus, the present study determined that ovarian carcinoma typically expresses low levels of TBX15 protein, predominantly due to an epigenetic mechanism. This may have a role in the pathogenesis of ovarian carcinoma independent of the histological subtype. PMID- 27698864 TI - Soluble purified recombinant C2ORF40 protein inhibits tumor cell growth in vivo by decreasing telomerase activity in esophageal squamous cell carcinoma. AB - The chromosome 2 open reading frame 40 (C2ORF40) gene is a candidate tumor suppressor gene for a variety of tumors. Previous results by the present authors revealed that the C2ORF40 protein is a secreted protein. However, the exact biological function of secreted C2ORF40 protein in carcinogenesis has not been thoroughly investigated. In the present study, the signal peptide sequence of the C2ORF40 cDNA was initially removed to produce secreted recombinant human C2ORF40 protein (rhC2ORF40). Soluble rhC2ORF40 was successfully expressed and purified, which was evaluated for the first time, to the best of our knowledge, for tumor suppressing function in vivo in esophageal cancer. The present results revealed that soluble purified rhC2ORF40 was concentrated with a purity of >95%. Furthermore, rhC2ORF40 inhibited esophageal cancer cell growth in vivo in a dose dependent manner compared with a control group (P<0.05). In addition, the present study demonstrated for the first time that rhC2ORF40 decreased telomerase activity using telomeric repeat amplification protocol-enzyme-linked immunosorbent assay (P<0.05), without affecting the expression levels of telomerase-component RNA (P>0.05), as shown with polymerase chain reaction. Overall, the present results demonstrated that soluble rhC2ORF40 inhibited tumor cell growth in vivo by decreasing telomerase activity in esophageal squamous cell carcinoma. Therefore, soluble rhC2ORF40 with a high purity and biological activity may be a potential biological therapy drug for esophageal cancer. PMID- 27698865 TI - Rapid increase in cystic volume of an anaplastic astrocytoma misdiagnosed as neurocysticercosis: A case report. AB - Reports describing a rapid increase in the cystic volume of anaplastic astrocytoma (AA) in a short time frame are rare. The present study reports the case of a 68-year-old male who was admitted to the No. 9 People's Hospital, Shanghai Jiaotong University School of Medicine (Shanghai, China), with a small cystic brain lesion and positive immunological testing for cysticercosis. Head magnetic resonance imaging (MRI) showed a cystic lesion, 6 mm in diameter, in the left frontal lobe. Neurocysticercosis was suspected and the patient was treated with a clinical trial of albendazole and steroids. A period of 25 days later, the patient's condition had deteriorated, and MRI revealed a cystic lesion in the left frontal lobe; thereafter, the cystic lesion was removed and a diagnosis of AA was established. The tumor was soft, ivory white and gelatinous due to myxoid degeneration. In this case, tumor-related angiogenesis and microvascular extravasation (blood-brain barrier disruption) may have been the main cause of the rapid increase in the cystic volume in such a short time frame. The similarity of the glioma and cysticercus antigens may have been the cause of the positive reactions in the cystic fluid. The present study reports the rare occurrence of a rapid increase of cystic volume and potential diagnostic difficulties. PMID- 27698866 TI - 4-isothiocyanate-2, 2, 6, 6-tetramethyl piperidinooxyl inhibits angiogenesis by suppressing VEGFR2 and Tie2 phosphorylation. AB - Reactive oxygen species (ROS) are involved in the signaling pathway and are triggered by angiogenic factors, including vascular endothelial growth factor and angiopoietins. 4-isothiocyanate-2, 2, 6, 6-tetramethyl piperidinooxyl (4-ISO Tempo) is one of the nitroxides that exhibits antioxidant activity. However, the anti-angiogenic effect of 4-ISO-Tempo remains unknown. The aim of this study was to investigate the effect of 4-ISO-Tempo on tumor proliferation and angiogenesis as well as its underlying mechanisms. Our results revealed that 4-ISO-Tempo significantly inhibited the viability of neoplastic and endothelial cells. Furthermore, the effective concentration of 4-ISO-Tempo on human microvascular endothelial cell 1 (HMEC-1) was lower than that on human lung adenocarcinoma A549 and human colon cancer SW620 cells. This suggested that endothelial cells were more sensitive to 4-ISO-Tempo than tumor cells. Furthermore, we demonstrated that 4-ISO-Tempo also suppressed secretion of matrix metalloproteinase (MMP)-2 and MMP 9, and migration and tube formation of HMEC-1 cells. The mechanism is attributed to the decreasing ROS generation and further phosphorylation of vascular endothelial growth factor receptor 2 and Tie2. Our findings suggest that 4-ISO Tempo should be investigated for its usefulness in anti-angiogenesis therapies. PMID- 27698867 TI - Long non-coding RNA H19 promotes the proliferation of fibroblasts in keloid scarring. AB - The expression of the long non-coding RNA (lncRNA) H19 is associated with proliferation in tumors. In order to investigate whether H19 may additionally mediate the proliferation of fibroblasts in human keloid disease, the present study collected samples from 24 subjects, including 8 with keloids, 8 with normal scars and 8 normal skin controls. Reverse transcription-polymerase chain reaction revealed that H19 levels were markedly increased in human keloids compared with normal scars and normal skin controls (P=0.017). In order to identify a potential role for H19 in the proliferative activity of human keloid fibroblasts, small interfering (si)RNA-mediated silencing experiments were performed. H19 siRNA treatment markedly inhibited the proliferation of keloid fibroblasts, as assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay (P=0.008). In order to identify the signaling mediators that are regulated by H19 in keloid fibroblasts, the expression levels of mammalian target of rapamycin (mTOR) and vascular endothelial growth factor (VEGF) were examined using western blotting. The results confirmed that knockdown of H19 inhibited mTOR and VEGF expression. In summary, the results indicate that H19 may be associated with increased proliferative activity of keloid fibroblasts, which may be mediated by mTOR and VEGF. PMID- 27698868 TI - Thymoquinone chemosensitizes colon cancer cells through inhibition of NF-kappaB. AB - In the present study, the effects and molecular mechanisms of thymoquinone (TQ) on colon cancer cells were investigated. Cell viability was determined using a Cell Counting Kit-8 assay, and the results revealed that treatment with TQ significantly decreased cell viability in COLO205 and HCT116 cells in a dose dependent manner. TQ treatment additionally sensitized COLO205 and HCT116 cells to cisplatin therapy in a concentration-dependent manner. To investigate the molecular mechanisms of TQ action, western blot analysis was used to determine the levels of phosphorylated p65 and nuclear factor-kappaB (NF-kappaB)-regulated gene products vascular endothelial growth factor (VEGF), c-Myc and B-cell lymphoma 2 (Bcl-2). The results indicated that TQ treatment significantly decreased the level of phosphorylated p65 in the nucleus, which indicated the inhibition of NF-kappaB activation by TQ treatment. Treatment with TQ also decreased the expression levels of VEGF, c-Myc and Bcl-2. In addition, the inhibition of NF-kappaB activation with a specific inhibitor, pyrrolidine dithiocarbamate, potentiated the induction of cell death and caused a chemosensitization effect of TQ in colon cancer cells. Overall, the results of the present study suggested that TQ induced cell death and chemosensitized colon cancer cells by inhibiting NF-kappaB signaling. PMID- 27698869 TI - RNA-seq analysis identifies key long non-coding RNAs connected to the pathogenesis of alcohol-associated head and neck squamous cell carcinoma. AB - Alcohol consumption has been implicated in the pathogenesis of head and neck squamous cell carcinoma (HNSCC), although its mechanism is poorly understood. Recent advances in the identification and understanding of long non-coding RNAs (lncRNAs) have indicated that these molecules have a profound effect on numerous biological processes, including tumorigenesis and oncogenesis. The present authors hypothesize that alcohol-mediated dysregulation of lncRNAs is a key event in HNSCC pathogenesis. An in silico differential expression analysis utilizing RNA sequencing (RNA-seq) data from 34 HNSCC patients, which included alcohol drinkers and non-alcohol drinkers, identified a panel of lncRNAs that were dysregulated due to alcohol consumption. Normal oral keratinocytes were then exposed to ethanol and acetaldehyde to validate the RNA-seq results. Two lncRNAs that were differentially expressed due to alcohol consumption were identified from RNA-seq analysis of the clinical data: lnc-PSD4-1 and lnc-NETO-1. Oral keratinocytes exposed to alcohol and acetaldehyde demonstrated dysregulation of these two lncRNAs, thus validating the results of RNA-seq analysis. In addition, low expression of the lnc-PSD4-1 isoform, lnc-PSD4-1:14, exhibited a strong correlation with high survival rates in a Cox proportional hazards regression model. Therefore, these lncRNAs may play a key role in the early pathogenesis of HNSCC, since they are dysregulated in both clinical data and in vitro experiments mimicking the effects of alcohol use. PMID- 27698870 TI - Association of FOXM1 expression with tumor histology and prognosis in Wilms tumor: Potential for a new prognostic marker. AB - Wilms tumor (WT) is the most common pediatric renal malignancy. A recent ontogenic model suggests that undifferentiated tumor state, and hence poor prognosis, in WT is determined by stabilization of beta-catenin in the nucleus. Forkhead box M1 (FOXM1) is a downstream component of the Wnt pathway and promotes nuclear localization of beta-catenin. As elevation of FOXM1 gene expression is prognostic in various types of malignancy, we hypothesized that high FOXM1 expression in WT is associated with undifferentiated histology and thus poor prognosis. In the current study, the expression of FOXM1 mRNA was determined in 46 WT specimens and 11 renal tissue controls from patients undergoing tumor nephrectomy, and these data were assessed with regard to clinicopathological parameters. The results demonstrated an upregulation of FOXM1 in WT by 10-fold compared to normal tissue. Expression differed significantly between controls and tumors of intermediate- and high-risk histopathology (P<0.001, Kruskal-Wallis), and distinguished normal tissue from tumors of good and adverse clinical outcome (P<0.001, Kruskal-Wallis). Notably, FOXM1 expression was significantly lower (P=0.009) in patients that received preoperative doxorubicin. These results suggest that FOXM1 may serve as a companion diagnostic factor for doxorubicin based therapies in WT. PMID- 27698872 TI - Radial forearm and forehead flap reconstruction following resection of a nasal arteriovenous malformation: A case report. AB - Arteriovenous malformation (AVM) is a structural vascular abnormality in which the arterial vasculature connects with the venous vasculature without capillary connections. AVM confined to the nasal cavity is considerably rare. Blurred vision can be one of the associated symptoms. A combined approach of complete surgical resection with prior superselective embolization is the treatment of choice. Following resection, the reconstruction of facial defects, particularly in the nasal area, is challenging. The present study reports the rare case of a patient with an AVM in the nasal cavity, in which embolization, resection and flap reconstruction were performed. Embolization and complete surgical resection were used to avoid recurrence. Subsequently, a combination of free radial forearm and forehead flaps was used for the reconstruction of the nasal defect, without prosthesis. To the best of our knowledge, this is the first report of AVM confined to the nasal cavity, managed by a combination of free radial forearm and forehead flap reconstruction following complete resection. The cosmetic results of the procedure were acceptable. PMID- 27698871 TI - Analysis of recurrence and survival rates in grade 3 endometrioid endometrial carcinoma. AB - The aim of the present study was to determine risk factors associated with recurrence and survival in patients with grade 3 endometrioid endometrial carcinoma (G3EEC). A retrospective analysis of 117 patients with G3EEC, who were admitted to the Obstetrics and Gynecology Hospital of Fudan University between January 2000 and December 2011, was performed. The chi2 test or Fisher's exact test were used for the comparison of categorical variables. Kaplan-Meier method was used for estimating recurrence-free survival (RFS), disease-specific survival (DSS) and overall survival (OS) rates. Univariate and multivariate Cox proportional hazards model were used to assess the prognostic significance of various patient characteristics. In 117 patients, 16 patients (13.7%) had tumor recurrence, of which 6 (37.5%) developed local-regional recurrence and 10 (62.5%) developed distant recurrence. Out of the 16 patients with tumor recurrence, 14 (87.5%) had a recurrence within 3 years of surgery. Statistically significant characteristics affecting RFS, DSS and OS rates were outer half myometrial invasion (MI >=50%), advanced International Federation of Gynecology and Obstetrics stage, positive lymph node metastasis (PLNM), lymph vascular space invasion, adnexal involvement and characterization as a high-risk group, according to the Gynecologic Oncology Group 99 stratification algorithm. RFS was associated with the depth of cervical mucosa (stromal) involvement. Furthermore, in the multivariate Cox proportional hazards model, significant independent adverse factors for RFS and DSS included MI >=50% and adnexal involvement. For OS, there were no statistically significant prognostic factors. In conclusion, MI >=50% and adnexal involvement are independent prognostic factors for RFS and DSS in G3EEC patients. PMID- 27698873 TI - Investigation of the association between mitochondrial DNA and p53 gene mutations in transitional cell carcinoma of the bladder. AB - Bladder carcinoma is the most common malignancy of the urinary tract. The major aim of the present study is to investigate the association between mitochondrial DNA (mtDNA) and p53 gene mutations in bladder carcinoma. A total of 30 patients with transitional cell carcinoma and 27 controls were recruited for the study. Bladder cancer tissues were obtained by radical cystectomy or transurethral resection. Genomic DNA was extracted from peripheral blood. mtDNA and p53 genes were amplified by polymerase chain reaction and sequenced directly. A total of 37 polymorphisms were identified, among which, 2 mutations were significant in the patient group, and 1 mutation was significant in the control group. Additionally, 5 different moderate positive correlations between mtDNA mutations and 3 different positive correlations between p53 gene and mtDNA mutations were detected. The high incidence of mtDNA and p53 gene mutations in bladder cancer suggests that these genes could be important in carcinogenesis.

AB - Ursolic acid is a type of pentacyclic triterpene compound with multiple pharmacological activities including cancer resistance, protection from liver injury, antisepsis, anti-inflammation and antiviral activity. The present study aimed to investigate the anticancer effect of ursolic acid. Ursolic acid activates cell apoptosis and its pro-apoptotic mechanism remains to be fully elucidated. Cell Counting kit-8 assays, flow cytometric analysis and analysis of caspase-3 and caspase-9 activity were used to estimate the anticancer effect of ursolic acid on DU145 prostate cancer cells. The protein expression of cytochrome c, rho-associated protein kinase (ROCK), phosphatase and tensin homolog (PTEN) and cofilin-1 were examined using western blot analysis. In the present study, ursolic acid significantly suppressed cell growth and induced apoptosis, as well as increasing caspase-3 and caspase-9 activities of DU145 cells. Furthermore, cytoplasmic and mitochondrial cytochrome c protein expression was significantly activated and suppressed, respectively, by ursolic acid. Ursolic acid significantly suppressed the ROCK/PTEN signaling pathway and inhibited cofilin-1 protein expression in DU145 cells. The results of the present study indicate that the anticancer effect of ursolic acid activates cell apoptosis through ROCK/PTEN mediated mitochondrial translocation of cofilin-1 in prostate cancer. PMID- 27698875 TI - Side population cells from long-term passage non-small cell lung cancer cells display loss of cancer stem cell-like properties and chemoradioresistance. AB - The side population (SP) assay is a widely used method for isolating stem cell like cells from cancer cell lines and primary cells. The cancer cells used in different laboratories have been passaged for different generations. Emerging evidence revealed that repeated passaging of cell lines for multiple generations frequently leads to change of characteristics. Thus, it is worth investigating the effects of repeated passaging on the biological and functional properties of the enriched SP fraction from early- and late-passage cells. The present study reports that the cancer stem cell (CSC) characteristics, including increased frequency of tumor-initiating and self-renewal capacity, and resistance to the chemotherapy agent doxorubicin and ionizing radiation, was diminished in SP cells from late-passage non-small cell lung cancer (NSCLC) cells. This finding revealed that the SP from long-term passage NSCLC cells was not consistently enriched for stem cell-like cancer cells, and low-passage cell lines and primary cancer cells are therefore recommended in the CSCs field. PMID- 27698876 TI - Eupatilin induces human renal cancer cell apoptosis via ROS-mediated MAPK and PI3K/AKT signaling pathways. AB - Phosphatidylinositol 3-kinase (PI3K)/AKT and mitogen activated protein kinase (MAPK) signaling cascades have significant roles in cell proliferation, survival, angiogenesis and metastasis of tumor cells. Eupatilin, one of the major compounds present in Artemisia species, has been demonstrated to have antitumor properties. However, the effect of eupatilin in renal cell carcinoma (RCC) remains to be elucidated. Therefore, the present study investigated the biological effects and mechanisms of eupatilin in RCC cell apoptosis. The results of the present study demonstrated that eupatilin significantly induced cell apoptosis and enhanced the production of reactive oxygen species (ROS) in 786-O cells. In addition, eupatilin induced phosphorylation of p38alpha (Thr180/Tyr182), extracellular signal-regulated kinase 1/2 and c-Jun N-terminal kinase 1/2 (Thr183/Tyr185), and decreased the phosphorylation of PI3K and AKT in 786-O cells in a concentration dependent manner. Furthermore, the ROS inhibitor N-acetyl-L-cysteine was able to rescue the MAPK activation and PI3K/AKT inhibition induced by eupatilin. Taken together, the results of the present study provide evidence that inhibition of eupatilin induces apoptosis in human RCC via ROS-mediated activation of the MAPK signaling pathway and inhibition of the PI3K/AKT signaling pathway. Thus, eupatilin may serve as a potential therapeutic agent for the treatment of human RCC. PMID- 27698877 TI - Inhibition of gamma-secretase activity synergistically enhances tumour necrosis factor-related apoptosis-inducing ligand induced apoptosis in T-cell acute lymphoblastic leukemia cells via upregulation of death receptor 5. AB - T-cell acute lymphoblastic leukemia (T-ALL) is a rare and aggressive hematopoietic malignancy prone to relapse and drug resistance. Half of all T-ALL patients exhibit mutations in Notch1, which leads to aberrant Notch1 associated signaling cascades. Notch1 activation is mediated by the gamma-secretase cleavage of the Notch1 receptor into the active intracellular domain of Notch1 (NCID). Clinical trials of gamma-secretase small molecule inhibitors (GSIs) as single agents for the treatment of T-ALL have been unsuccessful. The present study demonstrated, using immunofluorescence and western blotting, that blocking gamma secretase activity in T-ALL cells with N-[(3,5-difluorophenyl) acetyl]-L-alanyl-2 phenyl] glycine-1,1-dimethylethyl ester (DAPT) downregulated NCID and upregulated the tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) death receptor 5 (DR5). Upregulation of DR5 restored the sensitivity of T-ALL cells to TRAIL. Combination index revealed that the combined treatment of DAPT and TRAIL synergistically enhanced apoptosis compared with treatment with either drug alone. TRAIL combined with the clinically evaluated gamma-secretase inhibitor 3 [(1r, 4s)-4-(4-chlorophenylsulfonyl)-4-(2, 5-difluorophenyl) cyclohexyl] propanoic acid (MK-0752) also significantly enhanced TRAIL-induced cell death compared with either drug alone. DAPT/TRAIL apoptotic synergy was dependent on the extrinsic apoptotic pathway and was associated with a decrease in BH3 interacting-domain death agonist and x-linked inhibitor of apoptosis. In conclusion, gamma-secretase inhibition represents a potential therapeutic strategy to overcome TRAIL resistance for the treatment of T-ALL. PMID- 27698879 TI - A sesquiterpene lactone from Siegesbeckia glabrescens suppresses Hedgehog/Gli mediated transcription in pancreatic cancer cells. AB - Pancreatic cancer is aggressive and therefore difficult to treat; however, continued efforts have been made with the aim of developing an effective therapy against the disease. The Hedgehog (Hh) signaling pathway is reportedly involved in the proliferation and survival of pancreatic cancer cells. The transcription factor glioma-associated oncogene (Gli) is a key component of the Hh signaling pathway and the primary effector of pancreatic cancer development. Inhibiting Gli is a proven therapeutic strategy for this disease. The present study examined the regulation of Gli and the expression of its target genes to identify an inhibitor of the Sonic Hh (Shh) pathway. A germacranolide sesquiterpene lactone (GSL) was isolated from Siegesbeckia glabrescens as an inhibitor of Gli-mediated transcription. The results demonstrated that GSL inhibited Shh-induced osteoblast differentiation and Gli homolog 1 (Gli1)-mediated transcriptional activity in mesenchymal C3H10T1/2 stem cells. Furthermore, GSL suppressed Gli-mediated transcriptional activity in human pancreatic cancer PANC-1 and AsPC-1 cells, which resulted in reduced cancer cell proliferation and downregulated expression of the Gli-target genes, Gli1 and cyclin D1. A sesquiterpene lactone from S. glabrescens may therefore serve as a candidate for the treatment of Hh/Gli dependent pancreatic cancer. PMID- 27698878 TI - Tumor-suppressing effects of microRNA-429 in human renal cell carcinoma via the downregulation of Sp1. AB - MicroRNA (miR)-429 has been frequently reported to be downregulated in various tumors, including renal cell carcinoma (RCC), nasopharyngeal carcinoma, Ehrlich ascites tumor cells, gastric cancer, non-small cell lung cancer and endometrial endometrioid carcinoma. The present study investigated the effects of miR-429 on human RCC A498 and 786-O cells. Following transfection of cells with miR-429 mimics and scrambled control, MTT, cell migration, cell invasion and luciferase assays were performed. In addition, western blotting was performed in order to assess the expression of specificity protein 1 (Sp1), which was predicted to be a target of miR-429 by TargetScan. The present results revealed that miR-429 inhibited cell proliferation, migration and invasion of 786-O and A498 cells. In addition, the present results demonstrated that miR-429 overexpression downregulated Sp1 protein expression, which provides evidence that miR-429 may directly target Sp1 in RCC. These results suggest that miR-429 may be investigated for use as a predictive marker for early detection of tumor metastasis and blocking RCC cells from becoming invasive. PMID- 27698880 TI - Anticancer effect of deoxypodophyllotoxin induces apoptosis of human prostate cancer cells. AB - Deoxypodophyllotoxin (DPPT) is extracted and separated from citrus-related plants, including Podophyllum (P.) peltatum, P. pleianthum, P. emodi (also called P. hexandrum) and Diphylleia grayi. DPPT has significant antitumor and antiviral activity. However, due to its strong toxicity and side effects, its use is limited in practical applications. The in vitro antitumor efficacy of DPPT on human prostate cancer (PCa) cells remains to be determined. The present study investigated the anticancer effect of DPPT on human PCa cells and its potential mechanism. The data revealed that DPPT markedly reduced cell proliferation and activated the caspase-3 expression level by an increase in apoptotic cell death in DU-145 cells. In addition, treatment with DPPT markedly downregulated the levels of phosphorylated Akt and activated the p53/B-cell lymphoma 2 associated X protein (Bax)/phosphatase and tensin homolog (PTEN) signaling pathway in DU-145 cells, suggesting that caspase-mediated pathways were involved in DPPT-induced apoptosis. The present study suggested the role of DPPT as a novel chemotherapeutic drug for human PCa, which may function through the Akt/p53/Bax/PTEN signaling pathway. PMID- 27698882 TI - Metastatic extraskeletal Ewing's sarcoma treated with trabectedin: A case report. AB - The Ewing's sarcoma family of tumors (ESFT) comprises a number of rare malignant tumors. Standard first-line treatment for patients with these tumors includes chemotherapy with a five-drug regimen of vincristine, doxorubicin (Adriamycin(r)) and cyclophosphamide, alternating with ifosfamide and etoposide (VAC/IE). In cases of inadequate response, there are a number of second-line regimens available. However, further treatment options are required for those patients with disease unresponsive to standard treatment. Trabectedin is a novel treatment option for patients with ESFT. The present study reports the case of a Caucasian 69-year-old female patient who presented with a soft tissue mass on the chest wall that had developed 7 months earlier. A computed tomography scan revealed a 9*8*7-cm mass on the anterior chest wall above the pectoral muscle. Histopathological evaluations and molecular analysis indicated that it was consistent with a metastatic extraskeletal Ewing's sarcoma. The patient was treated with an alternating VAC/IE regimen; however, an inadequate response was observed. The patient received second-line treatment with a gemcitabine and dacarbazine combination regimen, but the disease progressed. Subsequently, treatment with trabectedin (1.5 mg/m2 as a 24-h continuous infusion every 3 weeks) was initiated. Trabectedin treatment resulted in long-lasting (18 months) progression-free survival. It is vital that novel drugs continue to being developed for patients with ESFT following progression subsequent to standard chemotherapy. The current report presents a case of a patient with metastatic, pre-treated Ewing's sarcoma achieving disease stabilization with trabectedin. Based on these results and the observed tolerability profile, trabectedin represents an alternative treatment for patients with ESFT. Further studies are required in order to determine the efficacy of trabectedin as monotherapy or in combination with other drugs. It is also important to identify which tumor subtypes, specific translocations and patient profiles will benefit the most from treatment with trabectedin. PMID- 27698881 TI - Impact of intense systemic therapy and improved survival on the use of palliative radiotherapy in patients with bone metastases from prostate cancer. AB - More effective drugs may reduce the requirement for palliative external beam radiotherapy for bony target volumes; however, living with metastases for prolonged periods of time may result in more frequent episodes of bone pain or serious skeletal-related events. The purpose of the present study was to evaluate how recent advances in systemic therapy impact radiotherapy utilization. A retrospective analysis of a comprehensive regional database was performed. All oncology care in this region was provided by only one center, assuring complete data. Patients that had succumbed between June 1, 2004 and June 1, 2015 were included. For all 236 patients, the median age at diagnosis of bone metastases was 75 years and median overall survival was 20 months. More intense systemic therapy was associated with a significantly longer survival time. Only 69 patients (29%) did not receive palliative radiotherapy for bony target volumes, whilst 1 course was given to 101 patients (43%), 2 courses to 34 patients (14%) and >2 courses to 32 patients (14%). Radiotherapy was used more frequently in younger patients, those with spinal cord compressions or pathological fractures, and those treated with intense and long-standing systemic therapy. Radiotherapy utilization increased with survival time. For 100 poor-prognosis patients that succumbed within 12 months, 57 courses of palliative radiotherapy were administered, whilst 100 patients that survived for 12-24 months were administered 114 courses (24-36 months, 148 courses). In conclusion, the use of palliative radiotherapy did not decrease when more effective systemic therapy was administered. However, provided that only 5% of patients received radionuclide treatment, additional studies in other populations are required. PMID- 27698883 TI - Identification of candidate target genes of genomic aberrations in esophageal squamous cell carcinoma. AB - The aim of the present study was to identify the candidate target genes of genomic aberrations in esophageal squamous cell carcinoma (ESCC). Array comparative genomic hybridization (CGH) and quantitative polymerase chain reaction were applied to analyze the copy number changes and expression level of candidate genes, respectively. Integrative analysis revealed that homozygous deletions of cyclin-dependent kinase inhibitor (CDKN) 2A and CDKN2B and gains of fascin actin-bundling protein 1 (FSCN1) and homer scaffolding protein 3 (HOMER3) occurred frequently in ESCC. The results demonstrated that the homozygous deletion of CDKN2A or CDKN2B was significantly associated with lymph node metastasis. Notably, the expression of CDKN2A and CDKN2B was lower in dysplasia than in normal esophageal epithelium. We also observed that the copy number increase of FSCN1 was significantly associated with pT, pN and pStage, and that the gain of HOMER3 was significantly linked with pN and pStage. We further revealed that FSCN1 and HOMER3 were overexpressed in ESCC, and that their overexpression was correlated with copy number increase. In conclusion, CDKN2A, CDKN2B, FSCN1 and HOMER3 are candidate cancer-associated genes and may play a tumorigenic role in ESCC. PMID- 27698884 TI - Comparable roles of CD44v8-10 and CD44s in the development of bone metastases in a mouse model. AB - Cluster of differentiation (CD)44 has been implicated in cancer metastasis to bone. Clinical and experimental studies have suggested that the standard isoform of CD44 (CD44s) and the variant isoform of CD44 (CD44v) enhance metastasis. The present study examined the differential roles of CD44s and CD44v, particularly CD44v8-10, in the development of bone metastases. For this purpose, MDA-MB-231 human breast cancer cells and A549 human lung cancer cells were stably transduced with epithelial splicing regulatory protein 1 (ESRP1), which regulates the alternative splicing of several genes, including CD44. The introduction of ESRP1 induced a splicing switch from CD44s to CD44v, particularly to CD44v8-10, while the total amount of CD44 was rarely affected. However, ESRP1 did not significantly affect cell proliferation, migration, invasion or tumor sphere formation in vitro. Furthermore, ESRP1 did not cause significant differences in the development of bone metastases in a mouse model. As an alternative approach, cancer cells transduced with the CD44v8-10 gene were also established. The overexpression of CD44v8-10 in MCF-7 human breast cancer cells, which rarely express any isoform of CD44, promoted cell migration and sphere formation, whereas the overexpression of CD44v8-10 in MDA-MB-231 cells, which endogenously express high levels of CD44s, did not exert these effects. The results of the present study collectively suggest that the ability of CD44v8-10 to promote tumor aggressiveness and bone metastases is similar to that of CD44s. CD44v8-10 and CD44s may represent potential therapeutic targets for the treatment of bone metastases. PMID- 27698885 TI - RANKL: A promising circulating marker for bone metastasis response. AB - Bone metastases are a frequent event in patients with solid tumors. Although great advances have been made in the treatment of these patients, the identification of novel, accurate indicators of bone response would greatly facilitate the clinical management of the disease. The receptor activator of nuclear factor-kappaB (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) signaling pathway is significantly involved in bone metastasis formation. The main aim of the present study was to evaluate the role of circulating RANK, RANKL and OPG levels in predicting bone response. Marker accuracy was also compared with that of the conventional tumor marker N-terminal telopeptide of type I collagen (NTX). A prospective study was performed on 49 patients with bone metastases from breast, lung and prostate cancer, who were undergoing treatment with zoledronic acid. Patients were monitored for 1 year with blood tests, clinical evaluation and instrumental exams according to the response evaluation criteria of the University of Texas M. D. Anderson Cancer Center (Houston, TX, USA) and the Positron Emission Tomography Response Criteria in Solid Tumors. Circulating RANK/RANKL/OPG transcripts and NTX levels were evaluated by reverse transcription quantitative polymerase chain reaction and immune enzymatic assay, respectively. The baseline RANKL levels differed significantly between responders and non responders, whereas no differences in NTX levels were observed between the two groups. Receiver operating characteristic curve evaluation for all markers revealed that RANKL was the most accurate marker, with an area under the curve of 0.74 (95% confidence interval, 0.54-0.93). In addition, RANKL, which is the target of the novel monoclonal antibody denosumab, was the most accurate predictor of bone response in the present series of patients with bone metastases. Thus, the use of RANKL as a marker could potentially improve clinical practice, as current bone response evaluation is still somewhat problematic. PMID- 27698886 TI - Programmed cell death 4 and BCR-ABL fusion gene expression are negatively correlated in chronic myeloid leukemia. AB - Programmed cell death 4 (PDCD4) is a tumor suppressor that inhibits carcinogenesis, tumor progression and invasion by preventing gene transcription and translation. Downregulation of PDCD4 expression has been identified in multiple types of human cancer, however, to date, the function of PDCD4 in leukemia has not been investigated. In the present study, PDCD4 mRNA and protein expression was investigated in 50 patients exhibiting various phases of chronic myeloid leukemia (CML) and 20 healthy individuals by reverse transcription quantitative polymerase chain reaction and western blot analysis. PDCD4 expression and cell proliferation was also investigated following treatment with the tyrosine kinase inhibitor, imatinib, in K562 cells. The results demonstrated that PDCD4 mRNA and protein expression was decreased in all CML samples when compared with healthy controls, who expressed high levels of PDCD4 mRNA and protein. No significant differences in PDCD4 expression were identified between chronic phase, accelerated phase and blast phase CML patients. In addition, PDCD4 expression was negatively correlated with BCR-ABL gene expression (r=-0.6716; P<0.001). Furthermore, K562 cells treated with imatinib exhibited significantly enhanced PDCD4 expression. These results indicate that downregulation of PDCD4 expression may exhibit a critical function in the progression and malignant proliferation of human CML. PMID- 27698887 TI - Effects of Hedera helix L. extracts on rat prostate cancer cell proliferation and motility. AB - Hedera helix L., a member of Araliaceae family, has antiproliferative, cytotoxic, antimicrobial, antifungal, antiprotozoal and anti-inflammatory effects, and is used in cosmetics. The aim of the present study was to investigate the effect of treatment with extracts of leaves and unripened fruits of H. helix on rat prostate cancer cell lines with markedly different metastatic potentials: Mat LyLu cells (strongly metastatic) and AT-2 cells (weakly metastatic). The effects of the extracts on cell kinetics and migration were determined. Tetrodotoxin was used to block the voltage-gated sodium channels (VGSCs) associated specifically with Mat-LyLu cells. Cell proliferation was detected spectrophotometrically using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay. The mitotic index was determined using the Feulgen staining method. Lateral motility was quantified by wound-healing assays. The results of the present study demonstrated that cell kinetics (proliferation and mitotic activity) and motility were inhibited by ethanolic leaf extract of H. helix. The ethanolic extract of H. helix fruit suppressed Mat-LyLu cell migration, with no effect on proliferation. The opposite effects were observed in AT-2 cells; migration was not affected but proliferation was inhibited. In conclusion, the ethanolic fruit extract of H. helix may inhibit the cell migration of Mat-LyLu cells by blocking VGSCs. However, the effect of ethanolic leaf extract of H. helix treatment on the lateral motility of the cancer cells is unclear. PMID- 27698888 TI - miRNA regulation of Sirtuin-1 expression in human astrocytoma. AB - Sirtuins are a family of 7 histone deacetylases largely involved in the regulation of cell proliferation, survival and death. The role of sirtuins in tumorigenesis and cancer progression has been previously studied in certain cancer types. Few studies have investigated sirtuin expression in gliomas, with controversial results. The aim of the present study was to investigate the expression of sirtuin-1 (Sirt-1) in diffuse astrocytoma [low grade astrocytoma (LGA)], anaplastic astrocytoma (AA) and glioblastoma multiforme (GBM) and in primary glioma cell lines: PLGAC (primary LGA cells); PAAC (primary AA cells); and PGBMC (primary GBM cells). Tumor samples were obtained from patients who underwent craniotomy for microsurgical tumor resection at the Neurosurgery Unit of the University of Messina between 2011 and 2014. Sirt-1 expression was qualitatively analyzed in 30 human glial tumor samples and 5 non-neoplastic brain tissue (NBT) specimens using immunohistochemistry and western blotting techniques. Sirt-1 expression was quantitatively analyzed by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). In addition, Sirt 1 expression in primary cell lines was investigated by immunoblotting and RT qPCR. Sirt-1 expression was downregulated in gliomas compared to NBTs. Sirt-1 levels also varied among different tumor grades, with more evident downregulation in high-grade (P<0.001) than low-grade tumors (P<0.01). These data were confirmed in cell lines, with the exception of upregulation of protein level in the highest malignancy grade cell lines. The present results suggest a role for miRNA-34a, miRNA-132 and miRNA-217 in the epigenetic control of Sirt-1 during gliomagenesis and progression, and demonstrate the different implications of Sirt-1 in human tissues and cell lines. Furthermore, the present results reveal that Sirt-1 may be an intrinsic regulator of tumor progression and the regulation of Sirt-1 involves complex molecular pathways. However, the biological functions of Sirt-1 in gliomagenesis require additional investigation. PMID- 27698889 TI - TGFB2 and BCL2L11 methylation in male laryngeal cancer patients. AB - DNA methylation is a major regulatory mechanism of gene expression. The aim of the present study was to test the association of transforming growth factor beta2 (TGFB2) and B cell lymphoma 2-like 11 (BCL2L11) gene methylation with the risk of laryngeal squamous cell carcinoma (LSCC). Using bisulfite pyrosequencing technology, DNA methylation levels of TGFB2 promoter and BCL2L11 gene-body CpG cytosines were measured in 90 LSCC tissues and 90 adjacent normal tissues. Analysis of variance and paired sample t-test were used to determine the association of gene methylation and the risk of LSCC. Our results revealed that there were no differences in TGFB2 and BCL2L11 methylation levels between the LSCC tissues and the paired normal tissues (P>0.05). Further breakdown analyses demonstrated that the association results of the two gene methylation levels and LSCC remained unchanged with the age, smoking history, histological differentiation or clinical stage of the LSCC patients (all adjusted P>0.05). In conclusion, there is no association of TGFB2 promoter and BCL2L11 gene-body methylation with the risk of LSCC in males. PMID- 27698890 TI - Quantitative detection of TUSC3 promoter methylation -a potential biomarker for prognosis in lung cancer. AB - Aberrant promoter methylation of tumor relevant genes frequently occurs in early steps of carcinogenesis and during tumor progression. Epigenetic alterations could be used as potential biomarkers for early detection and for prediction of prognosis and therapy response in lung cancer. The present study quantitatively analyzed the methylation status of known and potential gatekeeper and tumor suppressor genes [O-6-methylguanine-DNA methyltransferase (MGMT), Ras association domain family member 1A (RASSF1A), Ras protein activator like 1 (RASAL1), programmed cell death 4 (PDCD4), metastasis suppressor 1 (MTSS1) and tumor suppressor candidate 3 (TUSC3)] in 42 lung cancers and in corresponding non malignant bronchus and lung tissue using bisulfite-conversion independent methylation-quantification of endonuclease-resistant DNA (MethyQESD). Methylation status was associated with clinical and pathological parameters. No methylation was found in the promoter regions of PDCD4 and MTSS1 of either compartment. MGMT, RASSF1A and RASAL1 showed sporadic (up to 26.2%) promoter methylation. The promoter of TUSC3, however, was frequently methylated in the tumor (59.5%), benign bronchus (67.9%) and alveolar lung (31.0%) tissues from each tumor patient. The methylation status of TUSC3 was significantly associated with smaller tumor size (P=0.008) and a longer overall survival (P=0.013). Pooled blood DNA of healthy individuals did not show any methylation of either gene. Therefore, methylation of TUSC3 shows prognostic and pathobiological relevance in lung cancer. Furthermore, quantitative detection of TUSC3 promoter methylation appears to be a promising tool for early detection and prediction of prognosis in lung cancer. However, additional studies are required to confirm this finding. PMID- 27698891 TI - MMP-14 and TGFbeta-1 methylation in pituitary adenomas. AB - Pituitary adenoma (PA) is one of the most common abnormalities in the sellar region. Despite the fact that PA is a benign monoclonal neoplasm, it can cause serious complications, including ophthalmological, neurological and endocrinological abnormalities. Currently, the causes that increase the progression of tumors are unknown. Epigenetic silencing of the matrix metalloproteinase-14 (MMP-14) and transforming growth factor beta-1 (TGFbeta-1) genes may be associated with the development of PA, since these genes are important in the processes of tumor metastasis and angiogenesis. The purpose of the present study was to determine if the methylation status of the MMP-14 and TGFbeta-1 promoters is associated with PA development. In the present study, 120 tissue samples of PA were used. The methylation status of the MMP-14 and TGFbeta 1 promoters was investigated by methylation specific-polymerase chain reaction. Statistical analysis was conducted to investigate the associations between the methylation status, age and gender of PA patients, PA tumoral activity, recurrence and invasiveness. The MMP-14 gene was methylated in 30.00% (17/56 functioning and 19/64 non-functioning) of patients with PA, while the TGFbeta-1 gene was methylated in 13.33% (9/56 functioning and 7/64 non-functioning) of patients with PA. It was also observed that promoter methylation of MMP-14 correlated with the male gender (58.8 vs. 35.7%, P=0.022), while unmethylated (non-silenced) MMP-14 correlated with the female gender (64.3 vs. 41.7%, P=0.027). Associations between the promoter methylation status of the MMP-14 and TGFbeta-1 genes and PA functioning or recurrence were not identified. The present study reveals that silencing of the MMP-14 gene correlates with patients' gender. However, MMP-14 and TGFbeta-1 promoter methylation cannot be considered as a prognostic marker in PAs. PMID- 27698892 TI - Atypical presentation of a gastric stromal tumor masquerading as a giant intraabdominal cyst: A case report. AB - Gastrointestinal stromal tumors (GISTs) are mesenchymal neoplasms that arise in the gastrointestinal tract, accounting for ~1% of gastric malignancies. The present study reports the case of a GIST of the stomach in a 75-year-old man who presented with abdominal distension and anorexia for 1 month. Gastroscopy was unremarkable. Ultrasound and computed tomography (CT) scans showed a giant intraabdominal cystic lesion of unknown origin. The lesion was initially believed to be a duplication cyst, a pancreatic pseudocyst or a liver cyst in the pre operative diagnosis. Exploratory laparotomy revealed a cystic lesion of the lesser sac originating from the lesser curvature of the stomach. A distal gastrectomy with en bloc resection of the lesion was performed. The intraoperative frozen section showed a spindle-cell GIST and microscopically negative margins. The patient was treated with imatinib for 1 year. The latest CT scan at 14 months post-surgery did not show any recurrence. Although GISTs presenting as predominantly cystic lesions are very rare, they should be considered in the differential diagnosis of cystic lesions of the upper abdomen. PMID- 27698893 TI - miR-143 is associated with proliferation and apoptosis involving ERK5 in HeLa cells. AB - Inappropriate expression of microRNA (miR) is strongly associated with carcinogenesis. miR-143 was reported to be one of the most prominent miRs implicated in the genesis and progression of human cancer. However, its correlation with cell proliferation and apoptosis in cervical cancer remains to be fully elucidated. In the present study, it was demonstrated that miR-143 is able to suppress the proliferation of cervical cancer HeLa cells and induce cell apoptosis in a time- and dose-dependent manner. The present study also investigated the potential targets of miR-143, extracellular-signal-regulated kinase 5 (ERK5) and its downstream substrate oncoprotein c-Fos, both of which are involved in cell proliferation and apoptosis. Upon increasing the miR-143 level, the ERK5 and c-Fos protein expression was significantly decreased without the effect of ERK5 transcription. Therefore, miR-143 is able to suppress cell proliferation and induce apoptosis in HeLa cells, potentially through negative regulation of ERK5 at its post-transcriptional stage. PMID- 27698894 TI - AKT-STAT3 Pathway as a Downstream Target of EGFR Signaling to Regulate PD-L1 Expression on NSCLC cells. AB - While cancer development and progression can be controlled by cytotoxic T cells, it is also known that tumor-specific CD8+T cells become functionally impaired by acquiring a group of inhibitory receptors known as immune checkpoints. Amongst those, programmed death-1 (PD-1) is one of the most recognized negative regulators of T cell function. In non-small lung cancers (NSCLCs), the aberrant activation of epidermal growth factor receptor (EGFR) is known to induce PD-L1 expression and further the treatment with gefitinib, a tyrosine kinase inhibitor (TKI) for EGFR, decrease the expression of PD-L1 on NSCLC. Given the acquired resistance to gefitinib treatment frequently observed by developing secondary site mutations limiting its efficacy, it is important to understand the downstream mechanism of activated-EGFR signaling for regulating PD-L1 in NSCLC. In this study, we demonstrated that AKT-STAT3 pathway could be a potential target for regulating the surface expression of PD-L1 on NSCLCs with aberrant EGFR activity and, further, the inhibition of AKT or STAT3 activity could down regulate the expression of PD-L1 even in gefitinib-resistant NSCLCs. These results highlight an importance of AKT-STAT3 pathway as a promising target for potentiating anti-tumor immune responses by regulating PD-L1 expression on cancer cells with aberrant EGFR activity. PMID- 27698895 TI - African American Race is an Independent Risk Factor in Survival from Initially Diagnosed Localized Breast Cancer. AB - BACKGROUND: African American race negatively impacts survival from localized breast cancer but co-variable factors confound the impact. METHODS: Data sets were analyzed from the Surveillance, Epidemiology and End Results (SEER) directories from 1973 to 2011 consisting of patients with designated diagnosis of breast adenocarcinoma, race as White or Caucasian, Black or African American, Asian, American Indian or Alaskan Native, Native Hawaiian or Pacific Islander, age, stage I, II or III, grade 1, 2 or 3, estrogen receptor or progesterone receptor positive or negative, marital status as single, married, separated, divorced or widowed and laterality as right or left. The Cox Proportional Hazards Regression model was used to determine hazard ratios for survival. Chi square test was applied to determine the interdependence of variables found significant in the multivariable Cox Proportional Hazards Regression analysis. Cells with stratified data of patients with identical characteristics except African American or Caucasian race were compared. RESULTS: Age, stage, grade, ER and PR status and marital status significantly co-varied with race and with each other. Stratifications by single co-variables demonstrated worse hazard ratios for survival for African Americans. Stratification by three and four co-variables demonstrated worse hazard ratios for survival for African Americans in most subgroupings with sufficient numbers of values. Differences in some subgroupings containing poor prognostic co-variables did not reach significance, suggesting that race effects may be partly overcome by additional poor prognostic indicators. CONCLUSIONS: African American race is a poor prognostic indicator for survival from breast cancer independent of 6 associated co-variables with prognostic significance.

Recent advances of understanding tumor immunology and molecular drug development are leading us to the epoch of cancer immunotherapy. Some types of immunotherapy have shown to provide survival benefit for patients with solid tumors such as malignant melanoma, renal cell carcinoma, or non-small cell lung cancer. Several studies have suggested that immune checkpoint inhibition might be effective in some patients with gastrointestinal cancers. However, the era of cancer immunotherapy in gastrointestinal cancers is still in an inchoate stage. Here we briefly review the current status and perspective of immunotherapeutic approaches in patients with gastrointestinal cancers. PMID- 27698897 TI - Differential Roles of Carboxylated and Uncarboxylated Osteocalcin in Prostate Cancer Growth. AB - Serum levels of osteocalcin (OC), a bone matrix non-collagenous protein secreted by osteoblasts, are correlated with pathological bone remodeling such as the bone metastasis of cancer, as well as physiological bone turnover. The pathological roles in prostate cancer growth of the two existing types of serum OC, gamma carboxylated (GlaOC) and lower- (or un-) carboxylated (GluOC), have not yet been discriminatively examined. In the present study, we demonstrate that normal prostate epithelial cell growth was promoted by both types of OC, while growth of cancer cells in the prostate was accelerated by GlaOC but suppressed by GluOC. We suggest that OC regulates prostate cancer growth depending on the gamma carboxylation, in part by triggering reduced phosphorylation of receptor tyrosine kinases. PMID- 27698898 TI - MicroRNA Expression Profile on Solid Subtype of Invasive Lung Adenocarcinoma Reveals a Panel of Four miRNAs to Be Associated with Poor Prognosis in Chinese Patients. AB - According to the reclassification of lung adenocarcinoma (LAC) proposed in 2011, solid predominant lung adenocarcinoma (SPA) has been associated with poor outcomes for LAC patients. However, the prognostic value of the presence of solid subtype remains unclear. Besides, there is little data about the roles of microRNA (miRNA) in solid subtype of LAC. In this study, 243 LAC patients were classified into solid subtype positive and negative groups (S+ LAC, n=134 and S- LAC, n=109) according to whether the solid subtype was more than 5% of the tumor component or not. We analyzed the relationship between solid subtype and patients' outcome by univariate and multivariate analyses. Solid subtype was proved to be significantly associated with the 5-year overall survival and played as an independent prognostic factor for stage I-III invasive LAC patients. Then miRNA microarray was used to identify differentially expressed miRNAs in solid subtype, resulting in 31 differential miRNAs. Quantitative reverse transcription PCR (QRT-PCR) was used to validate 4 key miRNAs (miR-133b, miR-155-5p, miR-124 3p, miR-145-5p). Further, CCK-8 and transwell assays were performed to validate the impact of one dysregulated miRNA (miR-133b) on LAC cell function. Interestingly, while miR-133b could significantly inhibit the proliferation of A549 and SPC-A1, it showed no effect on the migration or invasion of LAC cell lines. These results suggest that solid subtype can exert independent prognostic impact on LAC patients, and 4 important dysregulated miRNAs in solid subtype of LAC may be involved in the malignancy of S+LAC, thus may further have clinical perspective for S+ LAC in the future. PMID- 27698899 TI - Is mTOR Inhibitor Good Enough for Treatment All Tumors in TSC Patients? AB - Tuberous sclerosis complex (TSC) is an autosomal dominant and multi-system genetic disorder in humans. TSC affects around 25,000 to 40,000 individuals in the United States and about 1 to 2 million individuals worldwide, with an estimated prevalence of one in 6,000 newborns. TSC occurs in all races and ethnic groups, and in both genders. TSC is caused by defects or mutations in two genes, TSC1 and TSC2. Loss of TSC1/TSC2 leads to dysregulation of mTOR, resulting in aberrant cell differentiation and development, and abnormal enlargement of cells. TSC is characterized by the development of benign and/or malignant tumors in several organs including renal/liver angiomyolipomas, facial angiofibroma, lymphangiomyomatosis, cardiac rhabdomyomas, retinal astrocytic, renal cell carcinoma, and brain subependymal giant cell astrocytomas (SEGA). In addition, TSC disease causes disabling neurologic disorders, including epilepsy, mental retardation and autism. Particularly problematic are the development of renal angiomyolipomas, which tend to be larger, bilateral, multifocal and present at a younger age compared with sporadic forms. In addition, SEGA block the flow of fluid within the brain, causing a buildup of fluid and pressure that leads to blurred vision and seizures. In the current review, we describe the pathology of TSC disease in key organs and summarize the use of mTOR inhibitors to treat tumors in TSC patients. PMID- 27698900 TI - Anti-inflammatory and Antitumor Activity of a Triple Therapy for a Colitis Related Colorectal Cancer. AB - Colorectal cancer (CRC) is an important health issue worldwide, accounting for the third place of cancer incidence. Chronic inflammation, as seen in Crohn's disease and ulcerative colitis, is the most important risk factor for developing CRC, as it favours neoplastic transformation by enhancing epithelial cell turnover in the colonic mucosa. Treatments for CRC need to be improved; currently they are not specific and have several secondary effects in patients. The main objective of this work was to evaluate a new therapeutic strategy against a colitis-related colorectal cancer in vivo and in vitro by targeting mTOR signaling and lactate dehydrogenase A. Together, these mechanisms directly affect tumor energetics. In this study we evaluated a better and more efficient triple therapy against a chronic inflammation-associated CRC in vivo and in vitro. After the development of tumors, mice were treated intraperitoneally during a forty-day period with single drugs or different combinations of Metformin, Sodium Oxamate and Doxorubicin. Targeted inhibition of the mTOR pathway, lactate dehydrogenase A and the concurrent use of Doxorubicin (called in this work as triple therapy), leaded to a notable reduction in the number and size of tumors in mice, and, a significant pro-inflammatory cytokines reduction Besides, we showed that treated cells were induced to early autophagy, and apoptosis cell death. Our results represent a novel and robust therapeutic strategy for overcoming CRC by means of targeting central molecular pathways in cancer by the combination of Metformin, Oxamate, and Doxorubicin leading to a rapid tumor growth inhibition and a dramatic colorectal crypt restoration. Besides, drug combination resulted in a notable reduction of anti-inflammatory cytokines. PMID- 27698901 TI - High Stoichiometry Phosphorylation of Talin at T144/T150 or S446 Produces Contrasting Effects on Calpain-mediated Talin Cleavage and Cell Migration. AB - Focal adhesions are large multi-protein complexes that serve as the linkage between extracellular matrix (ECM) and actin cytoskeleton and control the network of signaling cascades underlying cell migration. Talin plays a key role in focal adhesion turnover, and calpain-mediated proteolysis of talin is central to focal adhesion disassembly, but its regulation is not well elucidated. Here we demonstrate that talin phosphorylation at three high stoichiometry sites on its head domain, T144 and T150, or S446, have contrasting effects on calpain-mediated cleavage of talin and cell migration by using site-directed mutagenesis to inhibit phosphorylation. Expression of talinT144A+T150A stimulated calpain mediated cleavage of talin and accelerated focal adhesion disassembly, whereas expression of talinS446A fully inhibited talin cleavage by calpain, preventing focal adhesion disassembly. A large decrease in phospho-threonine or phospho serine levels was seen with talinT144A+T150A or talinS446A respectively, while more active ERK was present in talinT144A+T150A than in talinS446A. Cell adhesion and transwell assays using uniformly expressing cells showed that expression of talinT144A+T150A or talinS446A have opposing effects on cell adhesion and migration. These findings define and highlight the integral role of site-specific high stoichiometry phosphorylation of talin in regulating calpain-mediated cleavage of talin and focal adhesion disassembly, thus controlling adhesion stability, cell adhesion and ultimately, cell migration. PMID- 27698902 TI - MicroRNA-34c Suppresses Breast Cancer Migration and Invasion by Targeting GIT1. AB - Abnormal expression of microRNAs plays important role in tumor metastasis. Migration and invasion of cancer cells accord for the metastasis and deterioration of breast cancer. However, the regulatory role of microRNAs in the invasion and migration of breast cancer cells has not completely understood yet. Here we found that microRNA-34c (miR-34c) was significantly downregulated in metastatic tissue of breast cancer. In vitro study showed that miR-34c negatively regulated GIT1 protein expression by binding to the 3'UTR of GIT1 mRNA. Consistently, GIT1 protein expression was found upregulated significantly in metastatic breast cancer. Moreover, miR-34c overexpression suppressed the expression of GIT1 protein, and this effect was restored by AMO-miR-34c in breast cancer cells. Overexpression of miR-34c suppressed cell migration and invasion in both MCF-7 and MDA-MD-231 breast cancer cells. Furthermore, knockdown of endogenous GIT1 expression reduced the migration and invasion of both two breast cancer cells. Collectively, miR-34c downregulation in breast cancer cells resulted in the upregulation of GIT1, which in turn enhanced the migration and invasion of breast cancer. This study highlights molecular mechanism of migration and invasion of breast cancer cells. PMID- 27698903 TI - Prognostic Value of Plasma D-dimer in Patients with Resectable Esophageal Squamous Cell Carcinoma in China. AB - Background: Plasma D-dimer is closely related to prognosis in several cancers. The aim of the current study was to determine the prognostic value of plasma D dimer in patients with resectable esophageal squamous cell carcinoma (ESCC). Methods: A total of 337 patients with resectable ESCC were enrolled in this retrospective study. The 5-year cancer-specific survival (CSS) was calculated by Kaplan-Meier method. Cox regression analyses were performed to evaluate the prognostic factors. A nomogram model was also performed to predict the cancer prognosis. Results: In our study, there were 242 patients (71.8%) with plasma D dimer <= 0.5 MUg/ml and 95 patients (28.2%) with plasma D-dimer > 0.5 MUg/ml. There was a significantly better 5-year CSS in patients with plasma D-dimer <= 0.5 MUg/ml than patients with plasma D-dimer > 0.5 MUg/ml (35.5% vs. 21.1%, P < 0.001). Multivariate analyses reported that plasma D-dimer was an independent prognostic factor in patients with resectable ESCC (P < 0.001). In addition, a nomogram was also performed to predict the CSS. The Harrell's c-index was 0.68. Conclusion: We conclude that plasma D-dimer was an independent prognostic biomarker in patients with resectable ESCC. PMID- 27698904 TI - An Integrated Analysis of the Genome-Wide Profiles of DNA Methylation and mRNA Expression Defining the Side Population of a Human Malignant Mesothelioma Cell Line. AB - Intratumoral heterogeneity is a hallmark of all cancers and functions as the major barrier against effective cancer therapy. In contrast to genetic mutations, the role of epigenetic modifications in the generation and maintenance of heterogeneous cancer cells remains largely undetermined. This study was performed to evaluate the epigenetic mechanisms involved in the tumor cell heterogeneity using side population (SP) and non-SP cells isolated from a human malignant mesothelioma (HMM) cell line. The subpopulations of cancer cells were analyzed by methylated DNA immunoprecipitation combined with high-throughput sequencing (MeDIP-seq) and RNA-seq methodology. The RNA-seq data were analyzed with the MeDIP-seq data in an integrated way to identify the epigenetically modified genes that defined the SP. Concomitant changes in mRNA expression and DNA methylation were found in 122 genes, including 118 down-regulated genes with hypermethylation and 4 up-regulated genes with hypomethylation. Gene ontology revealed that a large portion of the genes belonged to the groups of biological processes such as stem cell maintenance, stem cell development, stem cell differentiation, and the negative regulation of the developmental process. Among these genes, BNC1, RPS6KA3, TWSG1 and DUSP15 contained aberrant methylation in the CpG islands of the promoter region, indicating that the genes regulated by DNA methylation characterized a distinct subpopulation of HMM cells. The present study provided valuable information to shed light on the epigenetic contributions to the generation and maintenance of tumor cell heterogeneity. PMID- 27698906 TI - Lentivirus-mediated Knockdown of HDAC1 Uncovers Its Role in Esophageal Cancer Metastasis and Chemosensitivity. AB - Histone deacetylationase 1 (HDAC1) is ubiquitously expressed in various cell lines and tissues and play an important role of regulation gene expression. Overexpression of HDAC1 has been observed in various types of cancers, which indicated that it might be a target for cancer therapy. To test HDAC1 inhibition for cancer treatment, the gene expression of HDAC1 was knockdown mediated by a lentivirus system. Our data showed the gene expression of HDAC1 could be efficiently knockdown by RNAi mediated by lentivirus in esophageal carcinoma EC109 cells. Knockdown of HDAC1 led to significant decrease of cell growth and altered cell cycle distribution. The result of transwell assay showed that the numbers of cells travelled through the micropore membrane was significantly decreased as HDAC1 expression was knockdown. Moreover, HDAC1 knockdown inhibited the migration of EC109 cells as determining by scratch test. Additionally, enhancement of cisplatin-stimulated apoptosis was detected by HDAC1 knockdown. Our data suggested inhibition of HDAC1 expression by lentivirus mediated shRNA might be further applied for esophageal cancer chemotherapy. PMID- 27698907 TI - Sample Level Enrichment Analysis of KEGG Pathways Identifies Clinically Relevant Subtypes of Glioblastoma. AB - Background: Glioblastoma is the most lethal primary brain tumor in adults. Aberrant signal transduction pathways, associated with the progression of glioblastoma, have been identified recently and may offer a potential gene therapy strategy. Methods and Findings: We first used the sample level enrichment analysis to transfer gene expression profile of TCGA dataset into pathway enrichment z-score matrix. Then, we classified glioblastoma into five subtypes (Cluster A to Cluster E) by the consensus clustering and silhouette analysis. Principle component analysis showed the five subtype could be separated by first three principle components. Integrative omics data showed that mesenchymal subtype was rich in Cluster A, neural subtype was centered in Cluster D and proneural subtype was gathered in Cluster E, while Cluster E showed a high percentage of G-CIMP subtype. Additionally, according to analyze the overall survival and progression free survival of each subtype by Kaplan-Merie analysis and Cox hazard proportion model, we identified Cluster D and Cluster E received a better prognosis. Conclusions: We report a clinically relevant classification of glioblastoma based on sample level KEGG pathway enrichment profile and this novel classification system provided new insights into the heterogeneity of glioblastoma, and may be used as an important clinical tool to predict the prognosis. PMID- 27698908 TI - Factors Influencing Clinicians' Choice of Adjuvant S-1 versus Capecitabine plus Oxaliplatin after Curative Gastrectomy in Patients with Gastric Cancer. AB - Purpose: Two recent randomized, phase III trials in Asia (ACTS-GC and CLASSIC) documented the survival benefit of postoperative chemotherapy after D2 lymph node dissection in patients with gastric cancer. We sought to determine what factors influenced clinicians' choices of either S-1 or capecitabine plus oxaliplatin (CAPOX) as adjuvant therapy after curative D2 gastrectomy. Materials and Methods: We retrospectively reviewed the clinicopathologic factors and adjuvant treatments for 435 patients from nine centers in Korea who were treated with either S-1 or CAPOX adjuvant chemotherapy after undergoing curative D2 gastrectomy between January 2013 and July 2014. Results: Of the 435 patients, 204 (46.9%) were treated with S-1 and 231 (53.1%) were treated with CAPOX. The median age at diagnosis was 61 years (range, 30-88). CAPOX was prescribed more often for patients who were 65 years of age or younger than for patients who were age 65 or older (77.1% vs. 22.9%, P<0.0001). Of the patients in stage II, 121 (60.8%) were treated with S-1 and 78 (39.2%) were given CAPOX; however, of those in stage III, 83 (35.2%) received S-1 and 153 (64.8%) were treated with CAPOX (P<0.0001). Conclusions: Clinicians only preferred CAPOX for younger patients with stage III gastric cancer after curative D2 gastrectomy. However, for elderly patients, clinicians more chose S-1 regardless of the stage. PMID- 27698905 TI - GSTT1 Null Genotype Significantly Increases the Susceptibility to Urinary System Cancer: Evidences from 63,876 Subjects. AB - GSTT1 gene plays an important role in detoxification and clearance of reactive oxygen species(ROS). A null variant in this gene has been demonstrated to confer cancer susceptibility. Although many studies have demonstrated the association between GSTT1 null polymorphism and urinary system cancer susceptibility, several publications reported opposite conclusions. For better understanding the effects of this polymorphism on the risk of urinary system cancer, a updated meta analysis was performed with a total of 26,666 cases and 37,210 controls extracted from 117 studies, by following the latest meta-analysis guidelines (PRISMA). The results suggested that the GSTT1 null genotype was significantly associated with an increased risk of urinary system cancer (OR=1.13, 95%CI=1.05-1.22). Furthermore, stratified analyses by the type of cancer, ethnicity, source of control and quality score presented a significantly increased risk associated with GSTT1 null genotype in bladder and prostate cancer subgroup, Caucasians and Indians subgroup, population-based(PB) subgroup, medium quality and low quality subgroup. Overall, our meta-analysis suggested that GSTT1 null genotype is a potential cancer susceptibility variant. Well-designed and large-cohort studies are needed to confirm the association between GSTT1 null genotype and urinary system cancer risk. PMID- 27698909 TI - Glutamate Decarboxylase 1 Overexpression as a Poor Prognostic Factor in Patients with Nasopharyngeal Carcinoma. AB - Background: Glutamate decarboxylase 1 (GAD1) which serves as a rate-limiting enzyme involving in the production of gamma-aminobutyric acid (GABA), exists in the GABAergic neurons in the central nervous system (CNS). Little is known about the relevance of GAD1 to nasopharyngeal carcinoma (NPC). Through data mining on a data set derived from a published transcriptome database, this study first identified GAD1 as a differentially upregulated gene in NPC. We aimed to evaluate GAD1 expression and its prognostic effect on patients with early and locoregionally advanced NPC. Methods: We evaluated GAD1 immunohistochemistry and performed an H-score analysis on biopsy specimens from 124 patients with nonmetastasized NPC receiving treatment. GAD1 overexpression was defined as an H score higher than the median value. The findings of such an analysis are correlated with clinicopathological behaviors and survival rates, namely disease specific survival (DSS), distant-metastasis-free survival (DMeFS), and local recurrence-free survival (LRFS) rates. Results: GAD1 overexpression was significantly associated with an increase in the primary tumor status (p < 0.001) and American Joint Committee on Cancer (AJCC) stages III-IV (p = 0.002) and was a univariate predictor of adverse outcomes of DSS (p = 0.002), DMeFS (p < 0.0001), and LRFS (p = 0.001). In the multivariate comparison, in addition to advanced AJCC stages III-IV, GAD1 overexpression remained an independent prognosticator of short DSS (p = 0.004, hazard ratio = 2.234), DMeFS (p < 0.001, hazard ratio = 4.218), and LRFS (p = 0.013, hazard ratio = 2.441) rates. Conclusions: Our data reveal that GAD1 overexpression was correlated with advanced disease status and may thus be a critical prognostic indicator of poor outcomes in NPC and a potential therapeutic target to facilitate the development of effective treatment modalities. PMID- 27698910 TI - Increased Prevalence of Esophageal Cancer in Areas with High Levels of Nickel in Farm Soils. AB - Background: Heavy metal pollution in farm soils is a grave concern in Taiwan. Previously, we found the incidence of oral cancer (OC) correlated positively with levels of nickel and arsenic in farm soils. Many OC patients have a second malignancy, among which esophageal cancer (EC) is the most common one in Taiwan. Objectives: We aimed to investigate whether these two cancers share some common risk factors. Methods: Taiwan began a compulsory national health insurance program in 1995. We used a database from this program to calculate the prevalence of EC and OC in Taiwan. We compared the prevalence of EC with prevalence of betel nut chewers in adults and the information of heavy metal in farm soils to look for any association. Results: The prevalence of OC and prevalence of EC were strongly correlated. The prevalence of betel nut chewing correlated with OC prevalence, but not with EC prevalence. An increased prevalence (1.9 fold) of EC was found where the farm soils contained high levels of nickel. Meanwhile, among the eight heavy metals studied, only the levels of nickel in the farm soils correlated statistically with the prevalence of EC. Conclusion: Nickel is probably a common environmental risk factor for esophageal cancer and oral cancer. PMID- 27698911 TI - XPG Gene Polymorphisms Contribute to Colorectal Cancer Susceptibility: A Two Stage Case-Control Study. AB - Previous studies have reported that xeroderma pigmentosum group G (XPG) gene polymorphisms may modulate colorectal cancer (CRC) susceptibility. In this study, we performed a two-stage case-control study to comprehensively investigate the associations of five polymorphisms in the XPG gene with CRC risk in 1,901 cases and 1,976 controls from Southern China, including rs2094258 C>T, rs751402 C>T, rs2296147 T>C, rs1047768 T>C and rs873601 G>A. After combining data from two stages, we found that three of the studied polymorphisms (rs2094258 C>T, rs751402 C>T, and rs873601 G>A) were significantly associated with CRC susceptibility. After adjustment for age and gender, multivariate logistic regression analysis indicated that carriers of the rs2094258 T alleles had an increased CRC risk [CT vs. CC: adjusted odds ratio (OR)=1.17, 95% confidence interval (CI)=1.01-1.36; TT vs. CC: adjusted OR=1.49, 95% CI=1.18-1.89; TT vs. CT/CC: adjusted OR=1.38, 95% CI=1.10-1.72]. Likely, rs873601 A allele also conferred increased CRC susceptibility. In contrast, a protective association was identified between rs751402 C>T polymorphism and the risk of CRC. In summary, our results indicated that these three polymorphisms were found to associate with CRC susceptibility in a Southern Chinese population. PMID- 27698912 TI - MiR-193a-5p Targets the Coding Region of AP-2alpha mRNA and Induces Cisplatin Resistance in Bladder Cancers. AB - Transcription factor AP-2 alpha (AP-2alpha or TFAP2A) is a newly identified prognostic marker of chemotherapy; its expression is positively correlated with chemosensitivity and survival of cancer patients. Using computational programs, we predicted that the coding region of AP-2alpha gene contains a potential miRNA response element (MRE) of miR-193a-5p, and the single nucleotide polymorphism (SNP) site (c.497A>G, rs111681798) resides within the predicted MRE. The results of luciferase assays and Western blot analysis demonstrated that miR-193a-5p negatively regulated the expression of AP-2alpha proteins, but have no influence on the mutant AP-2alpha (c.497A>G). Infection with lentiviral AP-2alpha gene or miR-193a-5p inhibitor in the bladder cancer cells decreased migration and cisplatin resistance, while knockdown of AP-2alpha gene or overexpression of miR 193a-5p in the urothelial cell line SV-HUC-1 increased migration and cisplatin resistances. We concluded that miR-193a-5p induced cisplatin resistance by repressing AP-2alpha expression in bladder cancer cells. PMID- 27698913 TI - Pretreatment TG/HDL-C Ratio Is Superior to Triacylglycerol Level as an Independent Prognostic Factor for the Survival of Triple Negative Breast Cancer Patients. AB - PURPOSE: Previous studies have reported that the triacylglycerol (TG) level and high-density lipoprotein cholesterol (HDL-C) are connected with breast cancer. However, the prognostic utility of the TG level and the TG/HDL-C ratio (THR) as conventional biomarkers in patients with triple negative breast cancer (TNBC) has not been elucidated. In this research, we investigate and compare the predictive value of the pretreatment serum TG level and THR in TNBC patients. METHODS: We evaluated 221 patients with TNBC who had pretreatment conventional blood biochemical examinations and calculated the THR. Univariate and multivariate logistic regression analyses were used to assess the effect of the TG level and the THR on overall survival (OS) and disease-free survival (DFS). RESULTS: The optimal cutoff values of the TG level and the THR were determined to be 0.935 mmol/L and 0.600, respectively. As shown in a Kaplan-Meier analysis, TNBC patients with a high TG level and THR had shorter OS and DFS than patients in the low-level groups (p < 0.05). The multivariate analysis suggested that the pretreatment THR level is an independent prognostic factor of OS (HR: 1.935; 95%CI: 1.032-3.629; p = 0.040) in TNBC patients. CONCLUSIONS: In conclusion, our data indicate that a high THR is an independent predictor and is superior to the TG level for predicting poor clinical outcomes in TNBC patients. PMID- 27698914 TI - Molecular Characterization and Enhancement of Anticancer Activity of Caffeic Acid Phenethyl Ester by gamma Cyclodextrin. AB - Caffeic Acid Phenethyl Ester (CAPE) is a key component in New Zealand propolis, known for a variety of health promoting and therapeutic potentials. We investigated the molecular mechanism of anticancer and anti-metastasis activities of CAPE. cDNA array performed on the control and CAPE-treated breast cancer cells revealed activation of DNA damage signaling involving upregulation of GADD45alpha and p53 tumor suppressor proteins. Molecular docking analysis revealed that CAPE is capable of disrupting mortalin-p53 complexes. We provide experimental evidence and demonstrate that CAPE induced disruption of mortalin-p53 complexes led to nuclear translocation and activation of p53 resulting in growth arrest in cancer cells. Furthermore, CAPE-treated cells exhibited downregulation of mortalin and several other key regulators of cell migration accountable for its anti metastasis activity. Of note, we found that whereas CAPE was unstable in the culture medium (as it gets degraded into caffeic acid by secreted esterases), its complex with gamma cyclodextrin (gammaCD) showed high efficacy in anti-tumor and anti-metastasis assays in vitro and in vivo (when administered through either intraperitoneal or oral route). The data proposes that CAPE-gammaCD complex is a potent anti-cancer and anti-metastasis reagent. PMID- 27698915 TI - Preoperative Lymphocyte-Monocyte Ratio Is a Predictor of Suboptimal Cytoreduction in Stage III-IV Epithelial Ovarian Cancer. AB - OBJECTIVE: To determine whether the preoperative lymphocyte-monocyte ratio (LMR) is a predictor of suboptimal cytoreduction in advanced-stage epithelial ovarian cancer (EOC). METHODS: Preoperative clinico-pathologic and hematologic parameters were reviewed in a total of 154 patients with EOC submitted to primary cytoreductive surgery. Patients were categorized into two different groups according to the results of cytoreductive surgery: optimal and suboptimal cytoreduction. Continuous variables were categorized into two groups using the best cutoff points selected on the receiver operating characteristic (ROC) curve for suboptimal cytoreduction. RESULTS: Based on data collected from the 154 patients, 133 (86.4%) and 21 (13.6%) patients presented with stage III and IV disease, respectively. One hundred seventeen (76.0%) patients had serous adenocarcinoma, and 92 (59.7%) had histologic tumor grade 3. The optimal and suboptimal cytoreduction groups included 96 (62.3%) and 58 patients (37.7%), respectively. The best LMR cutoff point for suboptimal cytoreduction was 3.75. On multivariate logistic regression analysis, age, cancer antigen 125, white blood cell count, and LMR were found to be the strongest predictors for suboptimal cytoreduction (P=0.0037, 0.0249, 0.0062, and 0.0015, respectively). Conclusion: Preoperative LMR is an independent predictor of suboptimal cytoreduction. It provides additional prognostic information beyond the biological parameters of the tumor. PMID- 27698916 TI - Diet- and Genetically-induced Obesity Produces Alterations in the Microbiome, Inflammation and Wnt Pathway in the Intestine of Apc+/1638N Mice: Comparisons and Contrasts. AB - Obesity is an established risk factor for colorectal cancer (CRC). Our previous study indicated that obesity increases activity of the pro-tumorigenic Wnt signaling. Presently, we sought to further advance our understanding of the mechanisms by which obesity promotes CRC by examining associations between microbiome, inflammation and Wnt-signaling in Apc+/1638N mice whose obesity was induced by one of two modalities, diet- or genetically-induced obesity. Three groups were employed: Apc+/1638NLepr+/+ fed a low fat diet (10% fat), Apc+/1638NLepr+/+ fed a high fat diet (60% fat, diet-induced obesity), and Apc+/1638NLeprdb/db fed a low fat diet (genetically-induced obesity). All animals received diets for 16 weeks from 8 to 24 weeks of age. The abundance of 19 bowel cancer-associated bacterial taxa were examined by real-time PCR. The abundance of Turicibacter and Desulfovibrio decreased, but F. prausnitizii increased, in diet induced obese mice (p < 0.05). In contrast, in genetically-induced obese mice, Bifidobacterium, A. muciniphila and E. rectale decreased, but Peptostrptococcus, and E. coli increased (p < 0.05). Both diet- and genetically-induced obesity altered the expression of genes involved in bacterial recognition (MyD88) and increased inflammation as indicated by elevated levels of cytokines (IFNgamma and TNF-alpha for genetically-induced obesity, and IL-6 for diet-induced obesity). The elevated inflammation was associated with altered expression of genes that are integral components of the Wnt-signaling cascade in a fashion indicating its activation. These findings demonstrate that the composition of the small intestinal microbiome is affected differently in diet- and genetically-induced obesity, but both are associated with elevated intestinal inflammation and alterations of the Wnt pathway towards enhancing tumorigenesis. PMID- 27698917 TI - Noninvasive Monitoring of Glioma Growth in the Mouse. AB - Malignant gliomas are the most common and deadly primary malignant brain tumors. In vivo orthotopic models could doubtless represent an appropriate tool to test novel treatment for gliomas. However, methods commonly used to monitor the growth of glioma inside the mouse brain are time consuming and invasive. We tested the reliability of a minimally invasive procedure, based on a secreted luciferase (Gaussia luciferase), to frequently monitor the changes of glioma size. Gluc activity was evaluated from blood samples collected from the tail tip of mice twice a week, allowing to make a growth curve for the tumors. We validated the correlation between Gluc activity and tumor size by analysing the tumor after brain dissection. We found that this method is reliable for monitoring human glioma transplanted in immunodeficient mice, but it has strong limitation in immunocompetent models, where an immune response against the luciferase is developed during the first weeks after transplant. PMID- 27698919 TI - Transketolase Serves a Poor Prognosticator in Esophageal Cancer by Promoting Cell Invasion via Epithelial-Mesenchymal Transition. AB - Background: To characterize the potential function and clinical significance of Transketolase (TKT) in esophageal cancer. Methods: High invasive esophageal squamous cell carcinoma (ESCC) cell line CE48T/VGH was used. Cellular functions in response to TKT modulation were examined, including cell growth, migration and invasion. The underlying molecules involved in the TKT regulatory mechanism were determined by western blot and confocal microscopic analysis. Clinically, TKT expressions in 76 ESCC patients were assessed by immunohistochemical (IHC) method, and the association with treatment outcome was determined. Results: TKT silencing inhibited cell migration and invasion but had a minimal effect on cell growth. This TKT silencing also induced the reversion of epithelial-mesenchymal transition (EMT), as evidenced by the spindle to cuboidal morphological change, increased the expression of epithelial markers (gamma-catenin), and decreased the levels of mesenchymal markers (fibronectin and N-cadherin). Mechanically, TKT was shown to modulate the EMT through the pERK-Slug/Snail-associated signaling pathway. Clinically, a high level of TKT in the cancer tissues of patients with esophageal squamous cell carcinoma was associated with poor survival (P = 0.042). In the multivariate analysis, a high TKT level was also shown to be an independent unfavorable prognostic factor (Odds ratio: 1.827, 95% confidence interval: 1.045-3.196, P = 0.035). Conclusions: TKT contributes to esophageal cancer by promoting cell invasion via meditating EMT process. Clinically, the over-expression of TKT in ESCC patients predicts poorer survival. TKT inhibition may be a useful strategy to intervene in cancer cell invasion and metastasis, which may lead to better prognosis for ESCC patients.

AB - Endometrial and ovarian cancers are two most common cancers affecting women in their post-menopausal years. To date, there are no simple biochemical tests to detect these cancers at early stages. Our previous study has demonstrated that the activity of total proprotein convertases (PCs) is significantly increased in uterine lavage at all stages of endometrial cancer, suggesting uterine lavage which can be obtained relatively non-invasively may provide a simple tool for the detection of endometrial cancer. However, uterine lavage may also contain ovarian derived factors, and PCs are also reported to be up-regulated in ovarian cancer. In this study we determined whether increases in uterine lavage PC activity are specific to endometrial cancer or are also associated with ovarian cancer. PC activity was detected in all uterine lavages examined but no difference was found between women with and without ovarian cancer. On the other hand, the PC activity was significantly higher in post-menopausal endometrial cancer patients, consistent with our previous report. These results suggest that measuring total PC activity in uterine lavage is a useful tool to detect endometrial cancer specifically. PMID- 27698918 TI - Plasma Circulating Cell-free DNA Integrity as a Promising Biomarker for Diagnosis and Surveillance in Patients with Hepatocellular Carcinoma. AB - The clinical significance of circulating cell-free DNA (cfDNA) integrity as diagnostic and surveillance biomarker in hepatocellular carcinoma (HCC) was investigated and compared to that of alpha fetoprotein (AFP). Liver cancer patients had lower cfDNA integrity than those with benign diseases (P = 0.0167) and healthy individuals (P = 0.0025). Patients with HCC and non-HCC liver cancers (P = 0.7356), and patients with benign diseases and healthy individuals (P = 0.9138) had comparable cfDNA integrity respectively. cfDNA integrity increased after hepatectomy in cancer patients (P = 0.0003). The AUCs for detecting HCC by cfDNA integrity and AFP were 0.705 (P = 0.005) and 0.605 (P = 0.156), respectively. We found cfDNA integrity decreased in HCC patients and has the potential as promising biomarker for HCC diagnosis and treatment surveillance. PMID- 27698922 TI - Potential Function of Exogenous Vimentin on the Activation of Wnt Signaling Pathway in Cancer Cells. AB - Cancer cell signaling, growth, morphology, proliferation and tumorigenic potential are largely depending on the signaling molecules present naturally in the tumor microenvironment and the identification of key molecules that drive the tumor progression is critical for the development of new modalities for the prevention of tumor progression. High concentrations of vimentin in the blood of cancer patients have been reported, however the function of blood circulating vimentin remains unknown. Here, we investigated the functional role of exogenously supplemented vimentin on colon cancer cells and examined the Wnt Signaling activation and cancer cell invasion. Vimentin when supplemented to the cancer cells remained bound to the surface of the cancer cells. Furthermore, bound vimentin activates Wnt signaling pathway as detectable by increased beta catenin accumulation in the nucleus with concomitant activation of beta-catenin dependent transcription of Wnt signaling downstream targets. Functionally, there was an increase in the rate of cellular invasion in these cancer cells upon binding with vimentin. Our results thus suggest that free vimentin in the tumor microenvironment acts as a positive regulator of the beta-catenin signaling pathway, thus providing a basis for cancer invasive properties. PMID- 27698921 TI - Interleukin-6 from Ovarian Mesenchymal Stem Cells Promotes Proliferation, Sphere and Colony Formation and Tumorigenesis of an Ovarian Cancer Cell Line SKOV3. AB - The origin of the majority of epithelial ovarian cancers (EOC) is regarded as extraovarian, with the ovary being the secondary site. The aim of this study was to explore the possible role of ovarian mesenchymal stem cells (OvMSCs) and secreted IL-6 in the development of EOC. OvMSCs were derived from normal ovarian stroma. Cell surface markers and differentiation capability were determined. The effects of IL-6 and conditioned medium of OvMSCs on the malignant phenotype of SKOV3 ovarian cancer cells were tested, and the status of STAT3 and ERK phosphorylation was investigated. OvMSCs had similar surface marker profiles as bone marrow mesenchymal stem cells, i.e., CD44 (+), CD90 (+) and CD45 (-), and was readily inducible to osteogenic, adipogenic and chondrogenic differentiation. OvMSCs secreted an extremely high level (>2500 pg/ml) of IL-6. Treatment of SKOV3 cells with conditioned media from OvMSCs increased cell proliferation, tumor sphere formation and anchorage independent growth, and resulted in activation of STAT3 but not ERK. Coinjection of OvMSCs with SKOV3 cell enhanced tumorigenesis in NOD-SCID mice. All of these behaviors were blocked by IL-6 receptor blocking antibody administered in vitro or in vivo. The OvMSCs alone injected into mice had no tumor growth after 3 months. By secreting high levels of IL-6, OvMSCs enhance the proliferation, sphere and colony formation and tumorigenesis of SKOV3 cells. PMID- 27698923 TI - Validation and Comparison of the 7th Edition of the American Joint Committee on Cancer Staging System and Other Prognostic Models to Predict Relapse-Free Survival in Asian Patients with Parotid Cancer. AB - Purpose: Parotid cancer is a rare malignancy characterized by a heterogeneous histologic subtype and distinct biologic behavior. The present study aimed to externally validate and compare the performances of the American Joint Committee on Cancer (AJCC) staging system (7th Edition), Carrillo score, and Vander Poorten score in the prediction of tumor relapse probability in a large cohort of Asian parotid cancer patients. Methods: In total, 261 patients who underwent primary surgery for localized parotid cancer between 2002 and 2014 at the four affiliated hospitals of Chang Gung Memorial Hospital were identified. All patients were categorized into different prognostic groups defined by these three models for the comparison of associated relapse-free survival (RFS) rates. Results: The 5 year overall survival, cancer-specific survival, and RFS rates were 82.9%, 86.2%, and 77.5%, respectively. All three models were significantly powerful in discriminating between the tumors of patients in the lowest and highest risk groups. The c-statistic for predicting the 5-year RFS was 0.74 for the AJCC staging, 0.74 for the Vander Poorten score, and 0.62 for the Carrillo score. The AJCC staging and Vander Poorten score gave significantly high c-statistic values compared to the Carrillo score. Conclusion: Our data validated that all three models are significantly powerful in discriminating tumor relapse between patients in lowest and highest risk groups. The AJCC system and Vander Poorten score proved superior to the Carrillo score, and showed similar performances in discriminating between the 5-year RFS probabilities of low and high-risk Asian parotid cancer patients. PMID- 27698925 TI - Low Proteolytic Clipping of Histone H3 in Cervical Cancer. AB - Chromatin in cervical cancer (CC) undergoes chemical and structural changes that alter the expression pattern of genes. Recently, a potential mechanism, which regulates gene expression at transcriptional levels is the proteolytic clipping of histone H3. However, until now this process in CC has not been reported. Using HeLa cells as a model of CC and human samples from patients with CC, we identify that the H3 cleavage was lower in CC compared with control tissue. Additionally, the histone H3 clipping was performed by serine and aspartyl proteases in HeLa cells. These results suggest that histone H3 clipping operates as part of post translational modification system in CC. PMID- 27698926 TI - FOLFIRINOX in Locally Advanced and Metastatic Pancreatic Cancer: A Single Centre Cohort Study. AB - Introduction: FOLFIRINOX is emerging as new standard of care for fit patients with locally advanced pancreatic cancer (LAPC) and metastatic pancreatic cancer (MPC). However, some of the physicians are reluctant to use FOLFIRINOX due to high toxicity rates reported in earlier studies. We reviewed our experience with FOLFIRINOX in LAPC and MPC, focussing on dose adjustments, toxicity and efficacy. Methods: We reviewed all patients with LAPC or MPC treated with FOLFIRINOX in our institution between April 2011 and December 2015. Unresectability (stage III and IV) was determined by the institution's multidisciplinary team for pancreatic cancer. Results: Fifty patients (18 LAPC and 32 MPC) were enrolled, with a median age of 55 years (IQR 49-66) and WHO performance status of 0/1. FOLFIRINOX was given as first-line treatment in 82% of patients. Dose modifications were applied in 90% of patients. The median number of completed cycles was 8 (IQR 5-9). Grade 3-4 toxicity occurred in 52% and grade 5 toxicity in 2%. The response rate was 25% (12% in LAPC, 32% in MPC). Median overall survival and progression-free survival were 14.8 and 10.3 months in LAPC, and 9.0 and 5.9 months in MPC, respectively. Overall 1- and 2-year survival was 65% and 10% in LAPC and 40% and 5% in MPC. Within the LAPC group, 6 patients (33%) underwent local ablative therapy and 1 patient (6%) a resection, leading to a median survival of 21.8 months. Conclusion: FOLFIRINOX treatment with nearly routine dose modification was associated with acceptable toxicity rates, relatively high response rates and an encouraging overall survival. PMID- 27698927 TI - Senescence Process in Primary Wilms' Tumor Cell Culture Induced by p53 Independent p21 Expression. AB - : Wilms tumor (WT) is an embryonal tumor occurring in developing kidney tissue. WT cells showing invasive cancer characteristics, also retain renal stem cell behaviours. In-vitro culture of WT is hampered by limited replicative potential. This study aimed to establish a longterm culture of WT cells to enable the study of molecular events to attempt to explain its cellular senescence. METHODS: Primary cell cultures from fresh WT tumor specimen were established. Of 5 cultures tried, only 1 could be propagated for more than 7 passages. One culture, identified as PSU-SK-1, could be maintained > 35 passages and was then subjected to molecular characterization and evaluation for cancer characteristics. The cells consistently harbored concomitant mutations of CTNNB1 (Ser45Pro) and WT1 (Arg413Stop) thorough the cultivation. On Transwell invasion assays, the cells exhibited migration and invasion at 55% and 27% capability of the lung cancer cells, A549. On gelatin zymography, PSU-SK-1 showed high expression of the matrix metaloproteinase. The cells exhibited continuous proliferation with 24-hour doubling time until passages 28-30 when the growth slowed, showing increased cell size, retention of cells in G1/S proportion and positive beta-galactosidase staining. As with those evidence of senescence in advanced cell passages, expression of p21 and cyclin D1 increased when the expression of beta-catenin and its downstream protein, TCF, declined. There was also loss-of-expression of p53 in this cell line. In conclusion, cellular senescence was responsible for limited proliferation in the primary culture of WT, which was also associated with increased expression of p21 and was independent of p53 expression. Decreased activation of the Wnt signalling might explain the induction of p21 expression. PMID- 27698928 TI - Phenylethanoid Glycosides from Cistanche tubulosa Inhibits the Growth of B16-F10 Cells both in Vitro and in Vivo by Induction of Apoptosis via Mitochondria dependent Pathway. AB - Cistanche tubulosa phenylethanoid glycosides (CTPG) have been shown various biological activities including anti-allergy, hepatoprotective activity and bone regeneration. However, the anti-tumor activity of CTPG needs to be investigated. CTPG was used to treat B16-F10 cells both in vitro and in vivo. We found that CTPG dramatically changed the morphology of B16-F10 cells, and significantly reduced the viability of B16-F10 cells in a dose-dependent and time-dependent manner, which might be mediated by CTPG-induced apoptosis and cell cycle arrest. After CTPG treatment, the expressions of BAX and BCL-2 were up-regulated and down regulated, respectively. Moreover, mitochondrial membrane potential was reduced and ROS generation was increased. Consequently, the levels of cytochrome c and cleaved-caspase-3 and -9 were up-regulated by CTPG treatment but not for cleaved caspase-8. We further observed that CTPG significantly inhibited the tumor growth in vivo and improved the survival rate of tumor mice. We also observed that CTPG promoted the proliferation of splenocytes and increased the proportions of CD4+ and CD8+ T cells in spleens of tumor mice. The results showed that CTPG induced the apoptosis of B16-F10 cells through mitochondria-dependent pathway, suggesting that CTPG could be a potential candidate for treatment of cancer. PMID- 27698924 TI - Long Non-coding RNAs in Urologic Malignancies: Functional Roles and Clinical Translation. AB - Early diagnosis and surveillance for metastasis and recurrences are critical issues of urologic cancer. Deregulation of long non-coding RNAs (lncRNAs) has been implicated in urologic malignancies and represents potential markers or therapeutic targets. However, the utility of lncRNA as biomarkers appears to be overstated due to heterogeneous or irreproducible results from different studies. Thus, a critical and cautious review on the biomarker potential of lncRNAs is needed. This review provides an update on new findings of lncRNA-based markers for urologic cancer. The diverse mechanisms and associated examples of lncRNAs involved during the carcinogenesis of prostate cancer, bladder cancer and renal cancer were discussed in a more balanced and critical manner, as were the suitability of lncRNAs as diagnostic or prognostics markers. PMID- 27698929 TI - ENaC/DEG in Tumor Development and Progression. AB - The epithelial Na+ channel/degenerin (ENaC/DEG) superfamily, including the acid sensing ion channels (ASICs), is characterized by a high degree of similarity in structure but highly diverse in physiological functions. These ion channels have been shown to be important in several physiological functions of normal epithelial cells, including salt homeostasis, fluid transportation and cell mobility. There is increasing evidence suggesting that ENaC/DEG channels are critically engaged in cancer cell biology, such as proliferation, migration, invasion and apoptosis, playing a role in tumor development and progression. In this review, we will discuss recent studies showing the role of ENaC and ASIC channels in epithelial cells and its relationship to the oncogenesis. PMID- 27698930 TI - Statins Dose-Dependently Exert Significant Chemopreventive Effects Against Various Cancers in Chronic Obstructive Pulmonary Disease Patients: A Population Based Cohort Study. AB - PURPOSE: Chronic obstructive pulmonary disease (COPD) is associated with an increased cancer risk. We evaluated the chemopreventive effect of statins against all cancers in COPD patients and identified the statin with the strongest chemopreventive effect. PATIENTS AND METHODS: All patients diagnosed with COPD at health care facilities in Taiwan (n = 116,017) from January 1, 2001, to December 31, 2012, were recruited. Each patient was followed to assess the following protective and risk factors for all cancers: age; sex; comorbidities (diabetes, hypertension, dyslipidemia) and the Charlson comorbidity index [CCI]); urbanization level; monthly income; and nonstatin drug use. The index date of statins use was the date of COPD confirmation. Propensity scores (PSs) were derived using a logistic regression model to estimate the effect of statins by considering the covariates predicting intervention (statins) receipt. To examine the dose-response relationship, we categorized statin use into four groups in each cohort (<28 [statin nonusers], 28-90, 91-365, and >365 cumulative defined daily dose). RESULTS: After PS adjustment for age, sex, CCI, diabetes, hypertension, dyslipidemia, urbanization level, and monthly income, we analyzed the all-cancer risk. The adjusted hazard ratios (aHRs) for the all-cancer risk were lower among statin users than among statin nonusers (aHR = 0.46, 95% confidence interval: 0.43 to 0.50). The aHRs for the all-cancer risk were lower among patients using rosuvastatin, simvastatin, atorvastatin, pravastatin, and fluvastatin than among statin nonusers (aHRs = 0.42, 0.55, 0.59, 0.66, and 0.78, respectively). Sensitivity analysis indicated that statins dose-dependently reduced the all-cancer risk. CONCLUSION: Statins dose-dependently exert a significant chemopreventive effect against various cancers in COPD patients. In particular, rosuvastatin has the strongest chemopreventive effect. PMID- 27698931 TI - The Efficacy of Bevacizumab in Different Line Chemotherapy for Chinese Patients with Metastatic Colorectal Cancer. AB - Objective: To evaluate the effect of bevacizumab in different lines for Chinese patients with metastatic colorectal cancer (mCRC). Methods: Patients of mCRC treated with bevacizumab or not at Sun Yat-sen University Cancer Center from 2007 to 2013 were recruited as study and control group. Endpoints were overall survival (OS), progression free survival (PFS), objective response rate (ORR) and disease control rate (DCR). Corresponding survival rates of first- and second line in study and control group were compared. Results: 1. Median OS of study and control group were 44.8 (95% CI: 37.1~52.4) months, 36.1 (95% CI: 32.8~39.5) months respectively, which were significantly different (P=0.004). 2. In the first line treatment, median OS of study and control group were 49.9(95% CI: 40.1~59.8) months and 36.1 (95% CI: 32.7~39.4) months (P=0.002), respectively. And median PFS were 10.1(95% CI: 8.7~11.5) months and 6.2 (95% CI: 5.5~6.8) months (P<0.001), respectively. 3. In the second line treatment, median OS of study and control group were 34.8 (95% CI: 26.3~43.3) months and 24.6 (95% CI: 22.2~27.0) months (P=0.022), respectively. And the mPFS were 6.3 (95% CI: 4.7~7.8) months and 3.1 (95% CI: 2.5~3.6) months (P<0.001), respectively. 4. Median OS of first- and second-line treatment of the study groups were 49.9(95% CI: 40.1~59.8) months and 34.8 (95% CI: 26.3~43.3) months (P=0.189), respectively. Conclusion: The combination of bevacizumab and chemotherapy had a promising efficacy in Chinese mCRC patients. However, their OS were statistically insignificant between first- and second-line of bevacizumab groups. PMID- 27698932 TI - Detecting Circulating Tumor DNA in Hepatocellular Carcinoma Patients Using Droplet Digital PCR Is Feasible and Reflects Intratumoral Heterogeneity. AB - PURPOSE: Circulating tumor DNA (ctDNA) is increasingly recognized as liquid biopsy to profile tumor genome. Droplet digital PCR (ddPCR) is a highly sensitive and easily operable platform for mutant detection. Here, we tried to detect ctDNA in hepatocellular carcinoma (HCC) patients using ddPCR. METHODS: Studies sequencing the genome of HCCs and COSMIC (Catalogue of Somatic Mutations in Cancer) database were reviewed to identify hotspot mutations. Circulating cell free DNAs (cfDNAs) extracted from 1 ml preoperative plasma sample were analyzed to detect circulating mutants using ddPCR. The DNAs from matched tumor and adjacent liver tissues or peripheral blood mononuclear cells (PBMCs) were sequenced to identify the origin of circulating mutants. RESULTS: Forty-eight HCC patients were enrolled and four gene loci, TP53 (c.747G>T), CTNNB1 (c.121A>G, c.133T>C), and TERT (c.1-124C>T) were chosen as targets for ddPCR assay. Serial dilution demonstrated the detection limit of ddPCR to be 0.01%. Twenty-seven patients (56.3%, 27/48) were found to have at least one kind of circulating mutants, with the mutant allele frequency ranging from 0.33% to 23.7%. Six patients (22.2%, 6/27) also had matched mutants in tumor tissues while none of the mutants were detected in adjacent liver tissues or PBMCs in all patients, which excluded the nonneoplastic origin of these circulating mutants and qualified them as ctDNA. CONCLUSIONS: ctDNA could be readily detected in HCC patients by targeting hotspot mutations using ddPCR and might reflect intratumoral heterogeneity. ctDNA detecting may serve as a promising liquid biopsy in HCC management. PMID- 27698934 TI - Reversal of Vascular Calcification and Aneurysms in a Rat Model Using Dual Targeted Therapy with EDTA- and PGG-Loaded Nanoparticles. AB - Degeneration of elastic lamina and vascular calcification are common features of vascular pathology such as aortic aneurysms. We tested whether dual therapy with targeted nanoparticles (NPs) can remove mineral deposits (by delivery of a chelating agent, ethylene diamine tetraacetic acid (EDTA)) and restore elastic lamina (by delivery of a polyphenol, pentagalloyl glucose (PGG)) to reverse moderate aneurysm development. EDTA followed by PGG NP delivery led to reduction in macrophage recruitment, matrix metalloproteinase (MMP) activity, elastin degradation and calcification in the aorta as compared to delivery of control blank NPs. Such dual therapy restored vascular elastic lamina and improved vascular function as observed by improvement in circumferential strain. Therefore, dual targeted therapy may be an attractive option to remove mineral deposits and restore healthy arterial structures in moderately developed aneurysms. PMID- 27698933 TI - Screening of Pleural Mesotheliomas for DNA-damage Repair Players by Digital Gene Expression Analysis Can Enhance Clinical Management of Patients Receiving Platin Based Chemotherapy. AB - BACKGROUND: Malignant pleural mesothelioma (MPM) is a rare, predominantly asbestos-related and biologically highly aggressive tumour leading to a dismal prognosis. Multimodality therapy consisting of platinum-based chemotherapy is the treatment of choice. The reasons for the rather poor efficacy of platinum compounds remain largely unknown. MATERIAL AND METHODS: For this exploratory mRNA study, 24 FFPE tumour specimens were screened by digital gene expression analysis. Based on data from preliminary experiments and recent literature, a total of 366 mRNAs were investigated using a Custom CodeSet from NanoString. All statistical analyses were calculated with the R i386 statistical programming environment. RESULTS: CDC25A and PARP1 gene expression were correlated with lymph node spread, BRCA1 and TP73 expression levels with higher IMIG stage. NTHL1 and XRCC3 expression was associated with TNM stage. CHECK1 as well as XRCC2 expression levels were correlated with tumour progression in the overall cohort of patients. CDKN2A and MLH1 gene expression influenced overall survival in this collective. In the adjuvant treated cohort only, CDKN2A, CHEK1 as well as ERCC1 were significantly associated with overall survival. Furthermore, TP73 expression was associated with progression in this subgroup. CONCLUSION: DNA-damage response plays a crucial role in response to platin-based chemotherapeutic regimes. In particular, CHEK1, XRCC2 and TP73 are strongly associated with tumour progression. ERCC1, MLH1, CDKN2A and most promising CHEK1 are prognostic markers for OS in MPM. TP73, CDKN2A, CHEK1 and ERCC1 seem to be also predictive markers in adjuvant treated MPMs. After a prospective validation, these markers may improve clinical and pathological practice, finally leading to a patients' benefit by an enhanced clinical management. PMID- 27698935 TI - Specific Inhibition of DNMT3A/ISGF3gamma Interaction Increases the Temozolomide Efficiency to Reduce Tumor Growth. AB - DNA methylation is a fundamental feature of genomes and is a candidate for pharmacological manipulation that might have important therapeutic advantage. Thus, DNA methyltransferases (DNMTs) appear to be ideal targets for drug intervention. By focusing on interactions existing between DNMT3A and DNMT3A binding protein (D3A-BP), our work identifies the DNMT3A/ISGF3gamma interaction such as a biomarker whose the presence level is associated with a poor survival prognosis and with a poor prognosis of response to the conventional chemotherapeutic treatment of glioblastoma multiforme (radiation plus temozolomide). Our data also demonstrates that the disruption of DNMT3A/ISGF3gamma interactions increases the efficiency of chemotherapeutic treatment on established tumors in mice. Thus, our data opens a promising and innovative alternative to the development of specific DNMT inhibitors. PMID- 27698936 TI - Magnetic Enrichment of Dendritic Cell Vaccine in Lymph Node with Fluorescent Magnetic Nanoparticles Enhanced Cancer Immunotherapy. AB - Dendritic cell (DC) migration to the lymph node is a key component of DC-based immunotherapy. However, the DC homing rate to the lymphoid tissues is poor, thus hindering the DC-mediated activation of antigen-specific T cells. Here, we developed a system using fluorescent magnetic nanoparticles (alpha-AP-fmNPs; loaded with antigen peptide, iron oxide nanoparticles, and indocyanine green) in combination with magnetic pull force (MPF) to successfully manipulate DC migration in vitro and in vivo. alpha-AP-fmNPs endowed DCs with MPF responsiveness, antigen presentation, and simultaneous optical and magnetic resonance imaging detectability. We showed for the first time that alpha-AP-fmNP loaded DCs were sensitive to MPF, and their migration efficiency could be dramatically improved both in vitro and in vivo through MPF treatment. Due to the enhanced migration of DCs, MPF treatment significantly augmented antitumor efficacy of the nanoparticle-loaded DCs. Therefore, we have developed a biocompatible approach with which to improve the homing efficiency of DCs and subsequent anti-tumor efficacy, and track their migration by multi-modality imaging, with great potential applications for DC-based cancer immunotherapy. PMID- 27698937 TI - Activation of GLP-1 Receptor Enhances Neuronal Base Excision Repair via PI3K-AKT Induced Expression of Apurinic/Apyrimidinic Endonuclease 1. AB - Glucagon-like peptide-1 (GLP-1) is an intestinal-secreted incretin that increases cellular glucose up-take to decrease blood sugar. Recent studies, however, suggest that the function of GLP-1 is not only to decrease blood sugar, but also acts as a neurotrophic factor that plays a role in neuronal survival, neurite outgrowth, and protects synaptic plasticity and memory formation from effects of beta-amyloid. Oxidative DNA damage occurs during normal neuron-activity and in many neurological diseases. Our study describes how GLP-1 affected the ability of neurons to ameliorate oxidative DNA damage. We show that activation of GLP-1 receptor (GLP-1R) protect cortical neurons from menadione induced oxidative DNA damage via a signaling pathway involving enhanced DNA repair. GLP-1 stimulates DNA repair by activating the cyclic AMP response element binding protein (CREB) which, consequently, induces the expression of apurinic/apyrimidinic endonuclease 1 (APE1), a key enzyme in the base excision DNA repair (BER) pathway. In this study, APE1 expression was down-regulated as a consequence phosphatidylinositol-3 kinase (PI3K) suppression by the inhibitor LY294002, but not by the suppression of MEK activity. Ischemic stroke is typically caused by overwhelming oxidative stress in brain cells. Administration of exentin-4, an analogue of GLP-1, efficiently enhanced DNA repair in brain cells of ischemic stroke rats. Our study suggests that a new function of GLP-1 is to elevate DNA repair by inducing the expression of the DNA repair protein APE1. PMID- 27698938 TI - Optical Imaging of Mesenchymal Epithelial Transition Factor (MET) for Enhanced Detection and Characterization of Primary and Metastatic Hepatic Tumors. AB - Purpose: To assess optical imaging of Mesenchymal-Epithelial Transition factor (MET) for delineation and characterization of intrahepatic models of human hepatocellular carcinoma (HCC) and metastatic colorectal cancer (CRC), and thereby demonstrate its potential use in precision oncology. Materials and Methods: MET expression in human CRC and HCC was assessed in tissue microarrays. We used GE-137, a modified cyanine 5-tagged peptide for MET targeting. HepG2 and Huh-7 (HCC) and HT-29 (CRC) cells with MET overexpression, and LNCaP cells (negative control) with minimal MET expression were incubated with the probe. Correlation between the relative fluorescence signal intensity and cellular MET expression level was assessed. Flow cytometry was used to assess probe specific binding and dissociation constant (Kd). Orthotopic xenograft models of human HCC and metastatic CRC were generated in nu/nu mice by subcapsular implantation of cells. Epifluorescence imaging was performed to capture the changes in deferential probe accumulation at different time points after injection. Target to-liver background ratio (TBR) was calculated and the probe biodistribution within different organs was assessed. Histopathologic analysis of extracted xenografts was performed to correlate the tumors MET expression with probe uptake by cancer cells. Results: Approximately 91.5% of HCC and 81% of CRC microarray cores showed MET expression. HCC and CRC cells incubated with the probe showed substantial fluorescence compared to control LNCaP, with strong correlation between fluorescence signal and MET expression (R2 = 0.99, p < 0.001). Probe binding affinity to MET (Kd) was measured to be 2.9 +/- 0.36 nM. Epifluorescence imaging showed intense uptake in subcapsular tumors with peak TBR of 5.46 +/- 0.46 in Huh-7, 3.55 +/- 0.38 in HepG2, and 15.93 +/- 0.61 in HT-29 orthotopic xenografts at 4 hours post-injection (mean +/- standard deviation). We demonstrated that in vivo probe uptake in xenografts is specific and can be blocked when co-injected with unlabeled peptide; for instance the epifluorescence TBR is reduced from 13.5 +/- 1.2 to 1.7 +/- 0.3 (p < 0.05) in HT-29 and from 5.3 +/- 0.8 to 1.4 +/- 0.2 (p < 0.05) in Huh-7 xenografts after co-injection with unlabeled peptides. Biodistribution studies showed predominantly renal clearance of the probe. Conclusion: Optical imaging of MET resulted in high TBR in animal models of primary and metastatic hepatic tumors suggesting its utility for procedural guidance. PMID- 27698939 TI - Size Dependent Kinetics of Gold Nanorods in EPR Mediated Tumor Delivery. AB - Gold nanorods (AuNR) have been intensively used in nanomedicine for cancer diagnostics and therapy, due to their excellent plasmonic photothermal properties. Tuning the size and aspect ratio of AuNR tailors the localized surface plasmon resonance (LSPR) in the NIR spectrum at which biological tissues are transparent, thus enables specific and effective treatment. The AuNR extravasates into tumor interstitium through enhanced permeation and retention (EPR) effect. Efficient AuNR based cancer therapy requires efficient AuNR tumor delivery. However, the size of AuNR can dramatically affect its blood circulation and tumor accumulation. Here we proposed for the first time a systematic framework to investigate the size-dependent kinetics of AuNRs during EPR mediated tumor delivery. By using 64Cu-labeled AuNRs with positron emission tomography (PET) and kinetic modeling, the in vivo uptake and kinetics of 64Cu-AuNR during its blood circulation, tumor accumulation and elimination were studied both in vitro and in vivo. The results of different sized AuNRs were compared and the optimum size of AuNR was suggested for EPR mediated tumor delivery. Our study provides a better understanding of the in vivo behavior of AuNR, which can help future design of nanomaterials for cancer imaging and therapy. PMID- 27698940 TI - Blocking the 4-1BB Pathway Ameliorates Crystalline Silica-induced Lung Inflammation and Fibrosis in Mice. AB - Long term pulmonary exposure to crystalline silica leads to silicosis that manifests progressive interstitial fibrosis, eventually leading to respiratory failure and death. Despite efforts to eliminate silicosis, clinical cases continue to occur in both developing and developed countries. The exact mechanisms of crystalline silica-induced pulmonary fibrosis remain elusive. Herein, we find that 4-1BB is induced in response to crystalline silica injury in lungs and that it is highly expressed during development of experimental silicosis. Therefore, we explore the role of 4-1BB pathway during crystalline silica-induced lung injury and find that a specific inhibitor blocking the pathway could effectively alleviate crystalline silica-induced lung inflammation and subsequent pulmonary fibrosis in vivo. Compared to controls, the treated mice exhibited reduced Th1 and Th17 responses. The concentrations of pro-inflammatory cytokines in bronchoalveolar lavage fluid (BALF), including tumor necrosis factor (TNF)-alpha, interferon (IFN)-gamma and interleukin (IL)-17A following crystalline silica challenge were also reduced in inhibitor-treated mice. Although there was no significant alteration in Th2 cytokines of IL-4 and IL-13, another type of pro-fibrogenic cell, regulatory T cell (Treg) was significantly affected. In addition, one of the major participants in fibrogenesis, fibrocyte recruited less due to the blockade. Furthermore, we demonstrated the decreased fibrocyte recruitment was associated with chemokine reductions in lung. Our study discovers the 4-1BB pathway signaling enhances inflammatory response and promotes pulmonary fibrosis induced by crystalline silica. The findings here provide novel insights into the molecular events that control crystalline silica-induced lung inflammation and fibrosis through regulating Th responses and the recruitment of fibrocytes in crystalline silica-exposed lung.

Here we report that miR-433 was consistently elevated in three models of heart disease with prominent cardiac fibrosis, and was enriched in fibroblasts compared to cardiomyocytes. Forced expression of miR-433 in neonatal rat cardiac fibroblasts increased proliferation and their differentiation into myofibroblasts as determined by EdU incorporation, alpha-SMA staining, and expression levels of fibrosis-associated genes. Conversely, inhibition of miR-433 exhibited opposite results. AZIN1 and JNK1 were identified as two target genes of miR-433. Decreased level of AZIN1 activated TGF-beta1 while down-regulation of JNK1 resulted in activation of ERK and p38 kinase leading to Smad3 activation and ultimately cardiac fibrosis. Importantly, systemic neutralization of miR-433 or adeno-associated virus 9 (AAV9)-mediated cardiac transfer of a miR-433 sponge attenuated cardiac fibrosis and ventricular dysfunction following myocardial infarction. Thus, our work suggests that miR-433 is a potential target for amelioration of cardiac fibrosis. PMID- 27698942 TI - Optimization of Early Response Monitoring and Prediction of Cancer Antiangiogenesis Therapy via Noninvasive PET Molecular Imaging Strategies of Multifactorial Bioparameters. AB - Objective: Antiangiogenesis therapy (AAT) has provided substantial benefits regarding improved outcomes and survival for suitable patients in clinical settings. Therefore, the early definition of therapeutic effects is urgently needed to guide cancer AAT. We aimed to optimize the early response monitoring and prediction of AAT efficacy, as indicated by the multi-targeted anti angiogenic drug sunitinib in U87MG tumors, using noninvasive positron emission computed tomography (PET) molecular imaging strategies of multifactorial bioparameters. Methods: U87MG tumor mice were treated via intragastric injections of sunitinib (80 mg/kg) or vehicle for 7 consecutive days. Longitudinal MicroPET/CT scans with 18F-FDG, 18F-FMISO, 18F-ML-10 and 18F-Alfatide II were acquired to quantitatively measure metabolism, hypoxia, apoptosis and angiogenesis on days 0, 1, 3, 7 and 13 following therapy initiation. Tumor tissues from a dedicated group of mice were collected for immunohistochemical (IHC) analysis of key biomarkers (Glut-1, CA-IX, TUNEL, alphanubeta3 and CD31) at the time points of PET imaging. The tumor sizes and mouse weights were measured throughout the study. The tumor uptake (ID%/gmax), the ratios of the tumor/muscle (T/M) for each probe, and the tumor growth ratios (TGR) were calculated and used for statistical analyses of the differences and correlations. Results: Sunitinib successfully inhibited U87MG tumor growth with significant differences in the tumor size from day 9 after sunitinib treatment compared with the control group (P < 0.01). The uptakes of 18F-FMISO (reduced hypoxia), 18F-ML-10 (increased apoptosis) and 18F-Alfatide II (decreased angiogenesis) in the tumor lesions significantly changed during the early stage (days 1 to 3) of sunitinib treatment; however, the uptake of 18F-FDG (increased glucose metabolism) was significantly different during the late stage. The PET imaging data of each probe were all confirmed via ex vivo IHC of the relevant biomarkers. Notably, the PET imaging of 18F-Alfatide II and 18F-FMISO was significantly correlated (all P < 0.05) with TGR, whereas the imaging of 18F-FDG and 18F-ML-10 was not significantly correlated with TGR. Conclusion: Based on the tumor uptake of the PET probes and their correlations with MVD and TGR, 18F-Alfatide II PET may not only monitor the early response but also precisely predict the therapeutic efficacy of the multi-targeted, anti-angiogenic drug sunitinib in U87MG tumors. In conclusion, it is feasible to optimize the early response monitoring and efficacy prediction of cancer AAT using noninvasive PET molecular imaging strategies of multifactorial bioparameters, such as angiogenesis imaging with 18F Alfatide II, which represents an RGD-based probe. PMID- 27698943 TI - Intracellular Trafficking Network of Protein Nanocapsules: Endocytosis, Exocytosis and Autophagy. AB - The inner membrane vesicle system is a complex transport system that includes endocytosis, exocytosis and autophagy. However, the details of the intracellular trafficking pathway of nanoparticles in cells have been poorly investigated. Here, we investigate in detail the intracellular trafficking pathway of protein nanocapsules using more than 30 Rab proteins as markers of multiple trafficking vesicles in endocytosis, exocytosis and autophagy. We observed that FITC-labeled protein nanoparticles were internalized by the cells mainly through Arf6 dependent endocytosis and Rab34-mediated micropinocytosis. In addition to this classic pathway: early endosome (EEs)/late endosome (LEs) to lysosome, we identified two novel transport pathways: micropinocytosis (Rab34 positive)-LEs (Rab7 positive)-lysosome pathway and EEs-liposome (Rab18 positive)-lysosome pathway. Moreover, the cells use slow endocytosis recycling pathway (Rab11 and Rab35 positive vesicles) and GLUT4 exocytosis vesicles (Rab8 and Rab10 positive) transport the protein nanocapsules out of the cells. In addition, protein nanoparticles are observed in autophagosomes, which receive protein nanocapsules through multiple endocytosis vesicles. Using autophagy inhibitor to block these transport pathways could prevent the degradation of nanoparticles through lysosomes. Using Rab proteins as vesicle markers to investigation the detail intracellular trafficking of the protein nanocapsules, will provide new targets to interfere the cellular behaver of the nanoparticles, and improve the therapeutic effect of nanomedicine. PMID- 27698944 TI - Gelatin-based Hydrogel Degradation and Tissue Interaction in vivo: Insights from Multimodal Preclinical Imaging in Immunocompetent Nude Mice. AB - Hydrogels based on gelatin have evolved as promising multifunctional biomaterials. Gelatin is crosslinked with lysine diisocyanate ethyl ester (LDI) and the molar ratio of gelatin and LDI in the starting material mixture determines elastic properties of the resulting hydrogel. In order to investigate the clinical potential of these biopolymers, hydrogels with different ratios of gelatin and diisocyanate (3-fold (G10_LNCO3) and 8-fold (G10_LNCO8) molar excess of isocyanate groups) were subcutaneously implanted in mice (uni- or bilateral implantation). Degradation and biomaterial-tissue-interaction were investigated in vivo (MRI, optical imaging, PET) and ex vivo (autoradiography, histology, serum analysis). Multimodal imaging revealed that the number of covalent net points correlates well with degradation time, which allows for targeted modification of hydrogels based on properties of the tissue to be replaced. Importantly, the degradation time was also dependent on the number of implants per animal. Despite local mechanisms of tissue remodeling no adverse tissue responses could be observed neither locally nor systemically. Finally, this preclinical investigation in immunocompetent mice clearly demonstrated a complete restoration of the original healthy tissue. PMID- 27698945 TI - Proto-Oncogenic Src Phosphorylates EB1 to Regulate the Microtubule-Focal Adhesion Crosstalk and Stimulate Cell Migration. AB - Cell migration, a complex process critical for tumor progression and metastasis, requires a dynamic crosstalk between microtubules (MTs) and focal adhesions (FAs). However, the molecular mechanisms underlying this event remain elusive. Herein we identify the proto-oncogenic protein Src as an important player in the regulation of the MT-FA crosstalk. Src interacts with and phosphorylates end binding protein 1 (EB1), a member of MT plus end-tracking proteins (+TIPs), both in cells and in vitro. Systematic mutagenesis reveals that tyrosine-247 (Y247) is the primary residue of EB1 phosphorylated by Src. Interestingly, both constitutively activated Src and Y247-phosphorylated EB1 localize to the centrosome and FAs. Src-mediated EB1 phosphorylation diminishes its interactions with other +TIPs, including adenomatous polyposis coli (APC) and mitotic centromere associated kinesin (MCAK). In addition, EB1 phosphorylation at Y247 enhances the rate of MT catastrophe and significantly stimulates cell migration. These findings thus demonstrate that the Src-EB1 axis plays a crucial role in regulating the crosstalk between MTs and FAs to promote cell migration. PMID- 27698946 TI - A New Concept of Enhancing Immuno-Chemotherapeutic Effects Against B16F10 Tumor via Systemic Administration by Taking Advantages of the Limitation of EPR Effect. AB - The enhanced permeability and retention (EPR) effect has been comfortably accepted, and extensively assumed as a keystone in the research on tumor-targeted drug delivery system. Due to the unsatisfied tumor-targeting efficiency of EPR effect being one conspicuous drawback, nanocarriers that merely relying on EPR effect are difficult to access the tumor tissue and consequently trigger efficient tumor therapy in clinic. In the present contribution, we break up the shackles of EPR effect on nanocarriers thanks to their universal distribution characteristic. We successfully design a paclitaxel (PTX) and alpha galactosylceramide (alphaGC) co-loaded TH peptide (AGYLLGHINLHHLAHL(Aib)HHIL-Cys) -modified liposome (PTX/alphaGC-TH-Lip) and introduce a new concept of immuno chemotherapy combination via accumulation of these liposomes at both spleen and tumor sites naturally and simultaneously. The PTX-initiated cytotoxicity attacks tumor cells at tumor sites, meanwhile, the alphaGC-triggered antitumor immune response emerges at spleen tissue. Different to the case that liposomes are loaded with sole drug, in this concept two therapeutic processes effectively reinforce each other, thereby elevating the tumor therapy efficiency significantly. The data demonstrates that the PTX/alphaGC-TH-Lip not only possess therapeutic effect against highly malignant B16F10 melanoma tumor, but also adjust the in vivo immune status and induce a more remarkable systemic antitumor immunity that could further suppress the growth of tumor at distant site. This work exhibits the capability of the PTX/alphaGC-TH-Lip in improving immune chemotherapy against tumor after systemic administration. PMID- 27698947 TI - Synthesis of thiazolidine-2,4-dione derivatives: anticancer, antimicrobial and DNA cleavage studies. AB - In the search of efficient anticancer agents, here, new 5-(4 alkylbenzyledene)thiazolidine-2,4-dione derivatives (5a-g) have been successfully synthesized and characterized and are evaluated for anticancer and antimicrobial activities using DNA cleavage studies. In vitro studies on anticancer activity of compound 5d (NSC: 768619/1) was done against the full panel of 60 human tumor cell lines. The five-level dose activity results revealed that, the compound 5d was active against all the cell lines, it has shown potential activity against leukemia SR (GI50: 2.04 MUM), non-small cell lung cancer NCI-H522 (GI50: 1.36 MUM), colon cancer COLO 205 (GI50: 1.64 MUM), CNS cancer SF-539 (GI50: 1.87 MUM), melanoma SK-MEL-2 (GI50: 1.64 MUM), ovarian cancer OVCAR-3 (GI50: 1.87 MUM), renal cancer RXF 393 (GI50: 1.15 MUM), prostate cancer PC-3 (GI50: 1.90 MUM), and breast cancer MDA-MB-468(GI50: 1.11 MUM). DNA cleavage studies revealed that at 50 MUg/mL concentration, partial DNA digestion was observed and when the concentration is increasing to threefold (150 MUg/mL), complete linear DNA digestion and partial supercoiled DNA digestion was observed. Further antimicrobial studies indicate that all the synthesized compounds except compound 5a possess prominent activity against all the screened microbial species. This study throws a ray of light in the field of anticancer drugs. PMID- 27698948 TI - Structural insight into binding mode of inhibitor with SAHH of Plasmodium and human: interaction of curcumin with anti-malarial drug targets. AB - S-adenosyl-L-homocysteine hydrolase of Plasmodium falciparum (PfSAHH) is a potential drug target against malaria, and selective inhibition of PfSAHH is the excellent strategy to prevent the growth of parasite inside the host. Therefore, a comparative analysis of human S-adenosyl-L-homocysteine hydrolase (HsSAHH) and PfSAHH has been performed to explore the structural differences. Structural superimposition of PfSAHH and HsSAHH has generated the RMSD of 0.749 A over 394 alpha carbon pairs. Residues of PfSAHH from position Tyr152 to Lys193 aligned with insertion/deletion region in HsSAHH, and these extra residues results in an extent of variation in cavity region of PfSAHH. Nicotinamide adenine dinucleotide (NAD) was observed to form hydrogen bonding with Thr201, Thr202, Thr203, Asn235, Val268, Glu287, Asn322, Ile343, Asn391, Lys473, and Tyr477 and also forms hydrophobic interactions with Val268, Ile288, and Thr320 of PfSAHH. In comparison to HsSAHH, Asn322, Lys473, and Tyr477 residues of PfSAHH are unique in interaction with NAD. 2-Fluoroaristeromycin and other analogues of aristeromycin have shown the good binding affinity for both enzymes. Structural differences between PfSAHH and HsSAHH might be employed to design the potential inhibitor of PfSAHH. To find the target enzyme responsible for an anti-malarial effect, molecular docking and interaction analysis of curcumin were performed with 34 drug targets of P. falciparum. Curcumin shows high affinity for binding with HGPRT of PfHGPRT, and an anti-malarial effect of curcumin might be due to binding with PfHGPRT. PMID- 27698949 TI - Influence of organic solvents on the structural and thermal characteristics of silk protein from the web of Orthaga exvinacea Hampson (Lepidoptera: Pyralidae). AB - The silk protein from the web of Orthaga exvinacea was isolated, purified, and casted into films. This film was treated separately with methanol, acetone, ethyl acetate, and isopropyl alcohol in 50 % concentration for about 30 min. The treated films were thus dried in a desiccator and subjected to FTIR and TG-DTA analysis. The structural studies revealed that the organic solvents induce conformatory changes in the protein film, especially the most sensitive amide I (1650 cm-1) band. This band had shifted to lower wavenumber (1633-1636 cm-1). Furthermore, the conformatory characteristics associated with amide I band also changed from random coil to beta-sheet. Generally, beta-sheet contributes strength to the protein film. Among the treated films, film treated with acetone showed much thermal stability. Moreover, the film treated with methanol had shown two different temperatures of maximum degradation. It is concluded that in addition to beta-sheet content, various other factors such as various processing conditions and structural organization of protein may influence the stability of the films.

AB - In this study, the synthesis of SBA-15/Ag nanocomposite materials with different amounts of silver (2.5, 5, and 10 %) has been investigated under acidic conditions by using P123 as a template via the direct method. The nanocomposites of SBA-15 were synthesized by the same method and by the addition of silver salt. Finally, the nanocomposite materials were examined for the removal of mercury ions from wastewater as an adsorbent by the reverse titration method. Characterization was carried out through x-ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and N2 adsorption-desorption (Brunauer-Emmett-Teller). XRD spectra confirmed the presence of silver nanoparticles within the amorphous silica matrix of SBA-15. The Barrett-Joyner-Halenda analysis showed that SBA-15 and SBA-15/Ag have a narrow pore size distribution. SEM images demonstrated that the morphology of the matrix of SBA-15 is in spherical state. Furthermore, wavelength dispersive x-ray spectroscopy identified the presence and distribution of silver nanoparticles inside the pore channels and outside of them. Typical TEM images of SBA-15 and SBA-15/Ag (5 wt.%) indicated a regular hexagonal pore structure with long-range order and long channels. In SBA-15/Ag (5 wt.%) sample, the nanoparticles of silver was found into the pores and outside of them. The removal of mercury ions from wastewater using mesoporous silica nanocomposite containing silver nanoparticles was studied by the reverse titration analysis. The best capacity of adsorption of mercury ions from wastewater was obtained for SBA-15/Ag (5 wt.%) sample, which was equal to 42.26 mg/g in 20 min at pH of 7. The Freundlich model was used to explain the adsorption characteristics for the heterogeneous surface, and [Formula: see text] (adsorption capacity) and n (adsorption intensity) were determined for Hg (II) ion adsorption on SBA-15/Ag nanocomposite materials with different amounts of silver (2.5, 5, and 10 %). The value of R2 was about 0.99, 0.99, 0.98, and 0.98 and Kf was about 42, 48, 58, and 58 mg/g for SBA-15/Ag, SBA 15/Ag (2.5 %), SBA-15/Ag (5 %), and SBA-15/Ag (10 %), respectively. Furthermore, the values of n >1 show a favorable adsorption process for Hg (II) ion adsorption on SBA-15/Ag nanocomposite materials. Moreover, the Langmuir isotherm model evaluation showed that the correlation coefficients for all concentrations were R2 >0.99, indicating that Hg (II) ions were adsorbed on the surface of SBA-15/Ag via chemical and physical interaction. Additionally, the analytic hierarchy process (AHP) and Technique of Order Preference Similarity to the Ideal Solution (TOPSIS) methods that depend on the criteria of the surface area, amount of adsorbent, pore volume, and cost of synthesis were used. The evaluation of results showed that the best sample was SBA-15/Ag (5 wt.%). Furthermore, the research work highlighted the antibacterial nanocomposite with suitable adsorption of Hg (II) ions from water solutions and supported its potential for environmental applications. This nanocomposite can be used in the absorption domain of Hg (II) ions from water solutions. PMID- 27698952 TI - Epigallocatechin-3-gallate Attenuates Renal Damage by Suppressing Oxidative Stress in Diabetic db/db Mice. AB - Epigallocatechin-3-gallate (EGCG), extracted from green tea, has been shown to have antioxidative activity. In the present study, we evaluated the effect of EGCG on the kidney function in db/db mice and also tried to investigate the underlying mechanism of the renoprotective effects of EGCG in both animals and cells. EGCG treatment could decrease the level of urinary protein, 8-iso-PGF2a, and Ang II. Moreover, EGCG could also change the level of several parameters associated with oxidative stress. In addition, the protein expression levels of AT-1R, p22-phox, p47-phox, p-ERK1/2, p-p38 MAPK, TGF-beta1, and alpha-SMA in diabetic db/db mice were upregulated, and all of these symptoms were downregulated with the treatment of EGCG at 50 and 100 mg/kg/d. Furthermore, the pathological changes were ameliorated in db/db mice after EGCG treatment. HK-2 cell-based experiments indicated that EGCG could inhibit the expression of MAPK pathways, which is the downstream effector of Ang II mediated oxidative stress. All these results indicated that EGCG treatment could ameliorate changes of renal pathology and delay the progression of DKD by suppressing hyperglycemia-induced oxidative stress in diabetic db/db mice. PMID- 27698953 TI - Training Enhances Immune Cells Mitochondrial Biosynthesis, Fission, Fusion, and Their Antioxidant Capabilities Synergistically with Dietary Docosahexaenoic Supplementation. AB - Exercise training induces adaptations in mitochondrial metabolism, dynamics, and oxidative protection. Omega-3 fatty acids change membrane lipid composition and modulate mitochondrial function. The aim was to investigate the effect of 8-week training and docosahexaenoic acid (DHA) supplementation (1.14 g/day) on the mitochondria dynamics and antioxidant status in peripheral blood mononuclear cells (PBMCs) from sportsmen. Subjects were assigned to an intervention (N = 9) or placebo groups (N = 7) in a randomized double-blind trial. Nutritional intervention significantly increased the DHA content in erythrocyte membranes from the experimental group. No significant differences were reported in terms of circulating PBMCs, Mn-superoxide dismutase protein levels, and their capability to produce reactive oxygen species. The proteins related to mitochondrial dynamics were, in general, increased after an 8-week training and this increase was enhanced by DHA supplementation. The content in mitofusins Mtf-1 and Mtf-2, optic atrophy protein-1 (Opa-1), and mitochondrial transcription factor A (Tfam) were significantly higher in the DHA-supplemented group after intervention. Cytochrome c oxidase (COX-IV) activity and uncoupling proteins UCP-2 and UCP-3 protein levels were increased after training, with higher UCP-3 levels in the supplemented group. In conclusion, training induced mitochondrial adaptations which may contribute to improved mitochondrial function. This mitochondrial response was modulated by DHA supplementation. PMID- 27698954 TI - Korean pine nut oil replacement decreases intestinal lipid uptake while improves hepatic lipid metabolism in mice. AB - BACKGROUND/OBJECTIVES: Consumption of pine nut oil (PNO) was shown to reduce weight gain and attenuate hepatic steatosis in mice fed a high-fat diet (HFD). The aim of this study was to examine the effects of PNO on both intestinal and hepatic lipid metabolism in mice fed control or HFD. MATERIALS/METHODS: Five-week old C57BL/6 mice were fed control diets containing 10% energy fat from either Soybean Oil (SBO) or PNO, or HFD containing 15% energy fat from lard and 30% energy fat from SBO or PNO for 12 weeks. Expression of genes related to intestinal fatty acid (FA) uptake and channeling (Cd36, Fatp4, Acsl5, Acbp), intestinal chylomicron synthesis (Mtp, ApoB48, ApoA4), hepatic lipid uptake and channeling (Lrp1, Fatp5, Acsl1, Acbp), hepatic triacylglycerol (TAG) lipolysis and FA oxidation (Atgl, Cpt1a, Acadl, Ehhadh, Acaa1), as well as very low-density lipoprotein (VLDL) assembly (ApoB100) were determined by real-time PCR. RESULTS: In intestine, significantly lower Cd36 mRNA expression (P < 0.05) and a tendency of lower ApoA4 mRNA levels (P = 0.07) was observed in PNO-fed mice, indicating that PNO consumption may decrease intestinal FA uptake and chylomicron assembly. PNO consumption tended to result in higher hepatic mRNA levels of Atgl (P = 0.08) and Cpt1a (P = 0.05). Significantly higher hepatic mRNA levels of Acadl and ApoB100 were detected in mice fed PNO diet (P < 0.05). These results suggest that PNO could increase hepatic TAG metabolism; mitochondrial fatty acid oxidation and VLDL assembly. CONCLUSIONS: PNO replacement in the diet might function in prevention of excessive lipid uptake by intestine and improve hepatic lipid metabolism in both control diet and HFD fed mice. PMID- 27698955 TI - Korean Curcuma longa L. induces lipolysis and regulates leptin in adipocyte cells and rats. AB - BACKGROUND/OBJECTIVES: Turmeric (Curcuma longa L.) has been reported to have many biological functions including anti-obesity. Leptin, peptide hormone produced by adipocytes and its concentration is increased in proportion to the amount of the adipocytes. In the present study, we examined the effects of Korean turmeric on the regulation of adiposity and leptin levels in 3T3-L1 adipocytes and rats fed a high-fat and high-cholesterol diet. MATERIALS/METHODS: Leptin secretion, free fatty acid and glycerol contents in 3T3-L1 adipocytes were measured after incubation of cells with turmeric for 24 hours. Rats were divided into four experimental groups: a normal diet group (N), a high-fat and high-cholesterol diet group (HF), a high-fat and high-cholesterol diet group supplemented with 2.5% turmeric extracts (TPA group) and a high-fat and high-cholesterol diet group supplemented with 5% turmeric extracts (TPB group). Serum samples were used for the measurement of leptin concentration. RESULTS: Contents of free fatty acid and glycerol showed concentration dependent increase in response to turmeric extracts. Effects of turmeric extracts on reduction of lipid accumulation in 3T3 L1 cells were examined by Oil Red O staining. Treatment with turmeric extracts resulted in increased expression levels of adipose triglyceride lipase and hormone-sensitive lipase mRNA. The concentration of leptin from 3T3-L1 adipocytes was significantly decreased by turmeric. Proportional abdominal and epididymal fats weights of the turmeric 5% supplemented group, TPB has significantly decreased compared to the HF group. The serum levels of leptin in the TPA and TPB groups were significantly lower than those of the HF group. CONCLUSIONS: Based on these results, we suggested that Korean turmeric may contribute to the decreasing of body fat and regulating leptin secretion. PMID- 27698957 TI - Corn silk extract improves cholesterol metabolism in C57BL/6J mouse fed high-fat diets. AB - BACKGROUND/OBJECTIVES: Corn silk (CS) extract contains large amounts of maysin, which is a major flavonoid in CS. However, studies regarding the effect of CS extract on cholesterol metabolism is limited. Therefore, the purpose of this study was to determine the effect of CS extract on cholesterol metabolism in C57BL/6J mouse fed high-fat diets. MATERIALS/METHODS: Normal-fat group fed 7% fat diet, high-fat (HF) group fed 25% fat diet, and high-fat with corn silk (HFCS) group were orally administered CS extract (100 mg/kg body weight) daily. Serum and hepatic levels of total lipids, triglycerides, and total cholesterol as well as serum free fatty acid, glucose, and insulin levels were determined. The mRNA expression levels of acyl-CoA: cholesterol acyltransferase (ACAT), cholesterol 7 alpha hydroxylase (CYP7A1), farnesoid X receptor (FXR), lecithin cholesterol acyltransferase (LCAT), low-density lipoprotein receptor, 3-hyroxy-3 methylglutaryl-coenzyme A reductase (HMG-CoA reductase), adiponectin, leptin, and tumor necrosis factor alpha were determined. RESULTS: Oral administration of CS extract with HF improved serum glucose and insulin levels as well as attenuated HF-induced fatty liver. CS extracts significantly elevated mRNA expression levels of adipocytokines and reduced mRNA expression levels of HMG-CoA reductase, ACAT, and FXR. The mRNA expression levels of CYP7A1 and LCAT between the HF group and HFCS group were not statistically different. CONCLUSIONS: CS extract supplementation with a high-fat diet improves levels of adipocytokine secretion and glucose homeostasis. CS extract is also effective in decreasing the regulatory pool of hepatic cholesterol, in line with decreased blood and hepatic levels of cholesterol though modulation of mRNA expression levels of HMG-CoA reductase, ACAT, and FXR. PMID- 27698956 TI - Blueberry, blackberry, and blackcurrant differentially affect plasma lipids and pro-inflammatory markers in diet-induced obesity mice. AB - BACKGROUND/OBJECTIVES: Evidence indicates that berry anthocyanins are anti atherogenic, antioxidant, and anti-inflammatory. However, berries differ vastly in their anthocyanin composition and thus potentially in their biological and metabolic effects. The present study compared hypolipidemic, antioxidant, and anti-inflammatory properties of blueberry (BB), blackberry (BK), and blackcurrant (BC) in a diet-induced obesity (DIO) mouse model. MATERIALS/METHODS: Male C57BL/6J mice were fed a high fat (HF; 35% fat, w/w) control diet or a HF diet supplemented with freeze-dried 5% BB, 6.3% BK or 5.7% BC for 12 weeks (10 mice/group) to achieve the same total anthocyanin content in each diet. Plasma lipids, antioxidant status and pro-inflammatory cytokines were measured. The expression of genes involved in antioxidant defense, inflammation, and lipid metabolism was determined in the liver, epididymal adipose tissue, proximal intestine, and skeletal muscle. Histological analysis was performed to identify crown-like structure (CLS) in epididymal fat pads to determine macrophage infiltration. RESULTS: No differences were noted between the control and any berry-fed groups in plasma levels of liver enzymes, insulin, glucose, ferric reducing antioxidant power, superoxide dismutase, and tumor necrosis factor alpha. However, BK significantly lowered plasma triglyceride compared with the HF control and other berries, whereas BC significantly reduced F4/80 mRNA and the number of CLS in the epididymal fat pad, indicative of less macrophage infiltration. CONCLUSIONS: The present study provides evidence that BB, BK and BC with varying anthocyanin composition differentially affect plasma lipids and adipose macrophage infiltration in DIO mice, but with no differences in their antioxidant capacity and anti-inflammatory potential. PMID- 27698958 TI - Gynura procumbens extract improves insulin sensitivity and suppresses hepatic gluconeogenesis in C57BL/KsJ-db/db mice. AB - BACKGROUND/OBJECTIVES: This study was designed to investigate whether Gynura procumbens extract (GPE) can improve insulin sensitivity and suppress hepatic glucose production in an animal model of type 2 diabetes. MATERIALS/METHODS: C57BL/Ksj-db/db mice were divided into 3 groups, a regular diet (control), GPE, and rosiglitazone groups (0.005 g/100 g diet) and fed for 6 weeks. RESULTS: Mice supplemented with GPE showed significantly lower blood levels of glucose and glycosylated hemoglobin than diabetic control mice. Glucose and insulin tolerance test also showed the positive effect of GPE on increasing insulin sensitivity. The homeostatic index of insulin resistance was significantly lower in mice supplemented with GPE than in the diabetic control mice. In the skeletal muscle, the expression of phosphorylated AMP-activated protein kinase, pAkt substrate of 160 kDa, and PM-glucose transporter type 4 increased in mice supplemented with GPE when compared to that of the diabetic control mice. GPE also decreased the expression of glucose-6-phosphatase and phosphoenolpyruvate carboxykinase in the liver. CONCLUSIONS: These findings demonstrate that GPE might improve insulin sensitivity and inhibit gluconeogenesis in the liver. PMID- 27698959 TI - Intake of antioxidants and B vitamins is inversely associated with ischemic stroke and cerebral atherosclerosis. AB - BACKGROUND/OBJECTIVES: This study was conducted to examine relationships between dietary habits and intakes of antioxidants and B vitamins and the risk of ischemic stroke, and to compare dietary factors according to the presence of cerebral artery atherosclerosis and stroke subtypes. SUBJECTS/METHODS: A total of 147 patients and 144 control subjects were recruited consecutively in the metropolitan area of Seoul, Korea. Sixty participants each in the case and control groups were included in analyses after 1:1 frequency matching. In addition, 117 acute ischemic stroke patients were classified into subtypes according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) guidelines. Dietary intake was measured using a semi-quantitative food frequency questionnaire composed of 111 food items and plasma lipid and homocysteine levels were analyzed. RESULTS: When compared with control subjects, stroke patients had unfavorable dietary behaviors and lower intakes of fruits (73.1 +/- 83.2 g vs. 230.9 +/- 202.1 g, P < 0.001), vegetables (221.1 +/- 209.0 g vs. 561.7 +/- 306.6 g, P < 0.001), and antioxidants, including vitamins C, E, B6, beta-carotene, and folate. The intakes of fruits, vegetables, vitamin C, and folate were inversely associated with the risk of ischemic stroke after adjusting for confounding factors. Intakes of vegetables, vitamins C, B6, B12, and folate per 1,000 kcal were lower in ischemic stroke with cerebral atherosclerosis than in those without. Overall vitamin B12 intake per 1,000 kcal differed according to the TOAST classification (P = 0.004), but no differences among groups existed based on the post-hoc test. CONCLUSIONS: When compared with control subjects, ischemic stroke patients, particularly those with cerebral atherosclerosis, had unfavorable dietary intake, which may have contributed to the development of ischemic stroke. These results indicate that proper dietary recommendations are important for the prevention of ischemic stroke. PMID- 27698960 TI - Effect of plate size on meal energy intake in normal weight women. AB - BACKGROUND/OBJECTIVES: Use of smaller plates to control food intake is a commonly recommended strategy for restricting energy intake, despite conflicting results. Therefore, the aim of this study was to examine whether or not three different sizes of plates influence energy intake during a multi-itemed buffet meal in normal weight women. SUBJECTS/METHODS: This was a cross-over study conducted on 37 female participants aged 19-25 years with normal BMI levels. Participants were recruited from Hacettepe University and the surrounding community. On experimental days, participants ate a standard breakfast and were then randomly assigned to eat lunch using a small (19 cm), medium (23 cm), or large (28 cm) diameter plate. Visual analogue scale (VAS) scores on sensory and satiety outcomes were measured for all meals. Energy and macronutrient intakes during lunch were recorded. RESULTS: There was no evidence that use of a smaller plate size reduced energy or specific macronutrient intake during the free choice lunch meal. Multiple visits to the serving table were not associated with energy or macronutrient intake. Plate size did not affect VAS scores during the test days. CONCLUSIONS: Plate size did not influence energy intake, meal composition, or palatability in normal weight women during a multi-itemed open buffet lunch. Studies in natural settings at the population level are needed to clarify current outcomes. PMID- 27698961 TI - Food deserts in Korea? A GIS analysis of food consumption patterns at sub district level in Seoul using the KNHANES 2008-2012 data. AB - BACKGROUND/OBJECTIVES: The concept of "food deserts" has been widely used in Western countries as a framework to identify areas with constrained access to fresh and nutritious foods, providing guidelines for targeted nutrition and public health programs. Unlike the vast amount of literature on food deserts in a Western context, only a few studies have addressed the concept in an East Asian context, and none of them have investigated spatial patterns of unhealthy food consumption from a South Korean perspective. SUBJECTS/METHODS: We first evaluated the applicability of food deserts in a Korean setting and identified four Korean specific unhealthy food consumption indicators, including insufficient food consumption due to financial difficulty, limited consumption of fruits and vegetables, excessive consumption of junk food, and excessive consumption of instant noodles. The KNHANES 2008-2012 data in Seoul were analyzed with stratified sampling weights to understand the trends and basic characteristics of these eating patterns in each category. GIS analyses were then conducted for the data spatially aggregated at the sub-district level in order to create maps identifying areas of concern regarding each of these indicators and their combinations. RESULTS: Despite significant reduction in the rate of food insufficiency due to financial difficulty, the rates of excessive consumption of unhealthy foods (junk food and instant noodles) as well as limited consumption of fruits and vegetables have increased or remained high. These patterns tend to be found among relatively younger and more educated groups, regardless of income status. CONCLUSIONS: A GIS-based analysis demonstrated several hotspots as potential "food deserts" tailored to the Korean context based on the observed spatial patterns of undesirable food consumption. These findings could be used as a guide to prioritize areas for targeted intervention programs to facilitate healthy food consumption behaviors and thus improve nutrition and food-related health outcomes. PMID- 27698962 TI - Dietary sugar intake and dietary behaviors in Korea: a pooled study of 2,599 children and adolescents aged 9-14 years. AB - BACKGROUND/OBJECTIVES: Dietary sugar intake, particularly added sugar and sugar sweetened beverages, has received worldwide attention recently. Investigation of dietary behaviors may facilitate understanding of dietary sugar intakes of children and adolescents. However, the relationship between dietary sugar intake and dietary behaviors in the Korean population has not been investigated. Thus, this study aimed to estimate dietary sugar intake and food sources according to sex as well as examine the relationship of dietary sugar intake with frequent snacking and dietary patterns among Korean children and adolescents. SUBJECTS/METHODS: We pooled data from five studies involving Korean children and adolescents conducted from 2002 to 2011. A total of 2,599 subjects aged 9-14 years were included in this study. Each subject completed more than 3 days of dietary records. RESULTS: Mean daily total sugar intake was 46.6 g for boys and 54.3 g for girls. Compared with boys, girls showed higher sugar intakes from fruits (7.5 g for boys and 8.8 g for girls; P = 0.0081) and processed foods (27.9 g for boys and 34.9 g for girls; P < 0.0001). On average, 95.4% of boys and 98.8% of girls consumed snacks during the study period, and total sugar intake showed a significantly increasing trend with increasing energy intake from snacks (P < 0.0001 for both sexes). Two dietary patterns were identified by cluster analysis: Traditional and Westernized patterns. Total sugar intake was higher in the Westernized pattern (56.2 g for boys and 57.2 g for girls) than in the Traditional pattern (46.5 g for boys and 46.3 g for girls). CONCLUSIONS: These results suggest that multilateral and practical development of a nutrition education and intervention program that considers dietary behaviors as well as absolute sugar intake is required to prevent excessive sugar intake in Korean children and adolescents. PMID- 27698963 TI - Perception of sugar reduction, nutrition education, and frequency of snacking in children by the self-perceived sweet dietary habits of mothers in Busan. AB - BACKGROUND/OBJECTIVES: The aim of this study was to investigate the perception of sugar reduction, nutrition education, and frequency of snacking in children according to the self-perceived dietary preferences for sweet taste by mothers in Busan. SUBJECTS/METHODS: A total of 277 mothers were surveyed, and their perceptions of sugar reduction and the frequency of snacking in children were assessed using a questionnaire. The subjects were classified into either a sweet (n = 91) or an unsweet (n = 186) group according to their self-perceived preferences for a sweet taste. RESULTS: In the sweet group, the results for sweet products were sweetened ice (86.8%), confectionery (74.7%), processed milk (73.6%), carbonated beverages (71.4%), and fermented milk (53.9%). In the unsweet group, the results were sweetened ice (88.7%), carbonated beverages (78.5%), processed milk (75.8%), confectionery (69.4%), and fermented milk (50.5%). The necessity of sugar intake reduction was high in both groups (sweet = 89.0%, unsweet = 82.8%). Beverage purchases after identifying the nutrition labeling was significantly lower in the sweet group than in the unsweet group (P < 0.05). The reasons for the beverage purchases instead of water were "habitually" (50.5%) and "like sweet taste" (25.3%) in the sweet group (P < 0.01). Snacking in children was significantly higher in the sweet group based on the increased frequencies of carbonated drinks (P < 0.01), fast food (P < 0.001), candy and chocolate (P < 0.05), crackers (P < 0.01), ramen (P < 0.01), and fish paste/hotdogs (P < 0.01). The frequency of purchase education after identifying the nutrition labeling was significantly lower in the sweet group than in the unsweet group (P < 0.01). CONCLUSIONS: These findings suggest that a perception of sugar reduction and practical nutrition education aimed at reducing the sugar intake are necessary to improve dietary habits. PMID- 27698964 TI - Child health promotion program in South Korea in collaboration with US National Aeronautics and Space Administration: Improvement in dietary and nutrition knowledge of young children. AB - BACKGROUND/OBJECTIVES: Childhood obesity has become a global epidemic. Development of effective and sustainable programs to promote healthy behaviors from a young age is important. This study developed and tested an intervention program designed to promote healthy eating and physical activity among young children in South Korea by adaptation of the US National Aeronautics and Space Administration (NASA) Mission X (MX) Program. SUBJECTS/METHODS: The intervention program consisted of 4 weeks of fitness and 2 weeks of nutrition education. A sample of 104 subjects completed pre- and post-surveys on the Children's Nutrition Acknowledgement Test (NAT). Parents were asked for their children's characteristics and two 24-hour dietary records, the Nutrition Quotient (NQ) at baseline and a 6-week follow-up. Child weight status was assessed using Korean body mass index (BMI) percentiles. RESULTS: At baseline, 16.4% (boy: 15.4%; girl: 19.2%) of subjects were overweight or obese (based on BMI>=85%tile). Fat consumption significantly decreased in normal BMI children (48.6 +/- 16.8 g at baseline to 41.9 +/- 18.1 g after intervention, P < 0.05); total NQ score significantly increased from 66.4 to 67.9 (P < 0.05); total NAT score significantly improved in normal BMI children (74.3 at baseline to 81.9 after the program), children being underweight (from 71.0 to 77.0), and overweight children (77.1 at baseline vs. 88.2 after intervention, P < 0.001). CONCLUSIONS: The 6 week South Korean NASA MX project is feasible and shows favorable changes in eating behaviors and nutritional knowledge among young children. PMID- 27698965 TI - Diet and the Gut. PMID- 27698968 TI - Seroprevalence of Hepatitis E Virus in Iran: A Systematic Review and Meta analysis. AB - BACKGROUND Hepatitis E virus (HEV) is one of common causes of viral hepatitis worldwide with higher prevalence in tropical and subtropical regions. Although epidemics of HEV have been reported from Iran, there are variable reports of this infection out of epidemics from different parts of Iran. This study aimed to determine the seroprevalence of HEV in Iran. METHODS In this systematic review and meta-analysis we searched PubMed, Scopus, Science direct, Google Scholar, Scientific Information Databank (SID), IranMedex, and Magiran for all relevant studies published in either English or Persian languages, up to 2015. Pooled seroprevalence estimates with a DerSimonian-Laird random-effects model were calculated. Statistical heterogeneity among the included studies was evaluated by Cochrane Q statistic and I2. RESULTS 38 studies fulfilled the inclusion criteria compromising 18461 participants. The pooled seroprevalence rate of HEV in Iran was estimated about 10% (95% CI=0.09-0.12) with maximum and minimum of 46% (95 % CI=0.42-0.50), and 0.01% (95 % CI=0.000-0.002), respectively. CONCLUSION HEV is common in Iran although the prevalence is lower than some neighbor countries. PMID- 27698967 TI - The Effect of Probiotic Plus Prebiotic Supplementation on the Tolerance and Efficacy of Helicobacter Pylori Eradication Quadruple Therapy: a Randomized Prospective Double Blind Controlled Trial. AB - BACKGROUND Standard anti-Helicobacter pylori (H. pylori) treatment fails in the eradication of the organism in almost 10-35% of the patients and has different side effects. Recent studies have proposed that probiotic supplementations with or without prebiotic may improve the eradication rate and diminish the side effects, although it is still a controversial issue. We aimed to investigate the effect of probiotic with prebiotic supplementation on the eradication rate and side effects of anti H. pylori quadruple therapy. METHODS 76 patients with a positive biopsy specimen for H. pylori were enrolled. They were randomized to receive quadruple therapy of bismuth, clarithromycin, amoxicillin, and omeprazole for 14 days and also the synbiotic or the placebo. We asked them to answer study questionnaires at the beginning and during the treatment. Finally, urea breath test was done 8 weeks after the treatment. RESULTS The eradication rate was significantly better in the synbiotic group by intention-to-treat analysis (p<0.05). Treatment side effects such as diarrhea, nausea, vomiting, epigastric pain, flatulence, constipation, and taste abnormality were similar in both groups but anorexia was significantly better in the synbiotic group (p <0.05). CONCLUSION The eradication rate was significantly better in the synbiotic group by intention-to-treat analysis (p<0.05). Treatment side effects such as diarrhea, nausea, vomiting, epigastric pain, flatulence, but could improve the eradication by augmenting the treatment tolerance and compliance. PMID- 27698969 TI - Factors Associated with Outcome in Patients with Acute Upper Gastrointestinal Bleeding in a Tertiary Referral Center in Northern Iran. AB - BACKGROUND Upper gastrointestinal bleeding (UGIB) is a major healthcare problem and is the most frequent gastrointestinal reason for admission to hospital. We aimed to investigate the prognosis of patients with UGIB referred to a referral hospital in northern Iran in 2013. METHODS All patients with UGIB who admitted to Sayyad Shirazi Hospital, in Gorgan, northern Iran, in 2013 were enrolled. The patients' demographic data as well as data about admission, diseases, drug history, and patients' prognosis were collected by structured questionnaire using information in hospital files. The relationships between different factors with the proportion of mortality and recurrence were assessed using Chi-square test. RESULTS In total, 168 patients were enrolled of whom 109 (64.9%) were male. The mean (SD) age of the patients was 59.4 (18.2) years. Mortality and recurrence occurred in 23.2% and 34.5% of the subjects, respectively. We found significant relationships between older age and diagnosis of malignancy with mortality (p =0.03 and p <0.01) and recurrence (p<0.01 and p <0.01). CONCLUSION We found relatively high rates of mortality and recurrence among patients with UGIB. Our results suggested older age and diagnosis of malignancy as the most important indicators of mortality and recurrence in such patients. Considering these factors in clinical settings may result in better and more effective management of patients with UGIB. PMID- 27698966 TI - New Concepts on Pathogenesis and Diagnosis of Liver Fibrosis; A Review Article. AB - Liver fibrosis is a potentially reversible response to hepatic insults, triggered by different chronic diseases most importantly viral hepatitis, alcoholic, and nonalcoholic fatty liver disease. In the course of the chronic liver disease, hepatic fibrogenesis may develop, which is attributed to various types of cells, molecules, and pathways. Activated hepatic stellate cell (HSC), the primary source of extracellular matrix (ECM), is fundamental in pathophysiology of fibrogenesis, and thus is the most attractable target for reversing liver fibrosis. Although, liver biopsy has long been considered as the gold standard for diagnosis and staging of hepatic fibrosis, assessing progression and regression by biopsy is hampered by its limitations. We provide recent views on noninvasive approaches including serum biomarkers and radiologic techniques. PMID- 27698970 TI - Association between Pattern of Gastritis and Gastroesophageal Reflux Disease in Patients with Helicobacter Pylori Infection. AB - : BACKGROUND Reflux disease is a common gastrointestinal problem. The association between reflux disease and gastritis pattern is controversial. AIM: To determine the association between reflux disease and gastritis pattern in patients with Helicobacter pylori (H. pylori) infection. METHODS 470 patients with dyspepsia and reflux disease were enrolled in this study. The inclusion criteria were willing to participate in the study, age over 40 years, and having the criteria of ROME III for at least 3 months. Patients with history of H. pylori eradication therapy during the 3 months before the study, a history of gastric surgery, and gastric cancer were excluded. All of the participants underwent upper endoscopy and two biopsy samples were taken from antrum, body, and fundal areas. RESULTS H. pylori infection rate was 367 (78.1%) with mean age of 59.8 +/- 11.4 years. Of them 131 patients (35.7%) were male. Reflux disease was detected in 273 (74.4%) patients. 216 (58.9%) and 102 (27.8%) patients had non-erosive reflux disease (NERD) and gastroesophageal reflux disease (GERD), respectively. Corpus predominant and antral predominant gastritis were seen in 72 (19.6%) and 129 (35.2%) patients, respectively. Antral gastritis was significantly associated with GERD (p<0.01). In regression analysis, antral predominant gastritis had a significant association with GERD (OR=1.92; 95%CI: 1.22- 3.12). The same result was observed in mild to moderate antral and greater curvature gastritis (OR= 1.26; 95%CI: 0.25-6.40 and OR= 3.0; 95%CI: 0.63-14.17, respectively). CONCLUSION According to these finding ,we could suggest that the pattern of gastritis could be associated with reflux disease and GERD. PMID- 27698972 TI - A Comparison between Hybrid and Concomitant Regimens for Helicobacter Pylori Eradication: A Randomized Clinical Trial. AB - BACKGROUND Helicobacter pylori (H. pylori) is one of the most common bacterial infections worldwide. We designed a study to compare the efficacy of 14-day hybrid regimen with 10-day concomitant therapy for H. pylori eradication in Iran. METHODS 252 patients with naive H. pylori infection were randomly divided to receive either hybrid regimen (pantoprazole 40 mg, and amoxicillin 1 gr twice daily for 14 days, accompanied by clarithromycin 500 mg, and metronidazole 500 mg, twice daily just during the last 7 days) or concomitant regimen (pantoprazole 40 mg, amoxicillin 1 gr, clarithromycin 500 mg, and metronidazole 500 mg, all twice daily for 10 days). 8 weeks after therapy, 14C- urease breath test was performed to confirm eradication. RESULTS According to intention to treat analysis, the eradication rates were 87.3% (95% CI: 81.4-93.1) and 80.9% (95% CI: 74-87.8) in hybrid and concomitant groups, respectively (p=0.38). Per-protocol eradication rates were 89.3% (95% CI: 83.8-94.7) and 83.1% (95% CI: 76.3-89.8), respectively (p=0.19). The rates of severe side effects were not statistically different between the two groups (4% vs. 8.7%). CONCLUSION 14-day hybrid therapy can be considered as a nearly acceptable regimen with few severe side effects in Iran. However, it seems that the efficacy of this therapy is decreasing as the resistance rates to antibiotics are increasing. We suggest further studies to assess the efficacy of a more prolonged concomitant therapy for H. pylori eradication in Iran. PMID- 27698971 TI - Accuracy of 99mTc (V)-Dimercaptosuccinic Acid Scintigraphy and Fecal Calprotectin Compared with Colonoscopy in Localizing Active Lesions in Inflammatory Bowel Disease. AB - INTRODUCTION Due to limitation of colonoscopy in assessing the entire bowel and patients' intolerance in inflammatory bowel disease (IBD), in the current study, we aimed to prospectively compare the accuracy of 99mTc(V)-dimercaptosuccinic acid (DMSA) and fecal calprotectin with ileocolonoscopy as new methods for localizing inflammations. METHODS Current prospective study conducted between 2012 and 2014 on 30 patients with IBD attending Gastroenterology Clinic of Tehran University of Medical Sciences. Fecal calprotectin and disease activity were measured for all participants and all of them underwent 99mTc (V)-DMSA scintigraphy and colonoscopy. The accuracy of 99mTc (V)-DMSA scintigraphy and calprotectin in localizing bowel lesions were calculated. RESULTS A total of 22 patients with ulcerative colitis (UC) and 8 patients with Crohn's disease (CD) were evaluated in our study. Sensitivity, positive likelihood ratio (PLR), and positive predictive value (PPV) of scintigraphy and calprotectin over colonoscopy in localization of UC lesions were 86.36%, 0.86%, 100.00% and 90.91%, 0.91, and 100.00%, respectively. Meanwhile, it showed 66.67% sensitivity and 81.25% specificity with PLR=3.56, negative likelihood ratio (NLR)=0.41, PPV=84.21%, and negative predictive value (NPV)= 61.90% in localizing lesions in patients with CD. The calprotectin level had sensitivity, PLR, and PPV of 90.00%, 0.90, and 100.00% in detecting active disease over colonoscopy, respectively. CONCLUSION The 99mTc (V)-DMSA scintigraphy would be an accurate method for detecting active inflammation in follow-up of patients with IBD and assessing response to treatment as a non-invasive and complementary method beside colonoscopy for more accurate diagnosis of CD or UC. PMID- 27698973 TI - Molecular and Immunohistochemical Study of Platelet Derived Growth Factor Receptor Alpha in KIT Negative Gastrointestinal Stromal Tumors; the First Report from Iran. AB - : BACKGROUND Gastrointestinal stromal tumors (GISTs) are potentially malignant tumors; however their behavior and response to treatment is dependent on the type of mutation and immunohistochemical expression of antigens. It is recommended to perform routine molecular and immunohistochemical tests in KIT and platelet derived growth factor receptor alpha (PDGFRA) molecules for making decision regarding targeted therapy and prediction of the behavior of the tumor. OBJECTIVES: There has been no study from Iran regarding the PDGFRA mutational analysis in GISTs. In this study, for the first time from Iran, we performed immunohistochemical and molecular analysis of PDGFRA molecule on GISTs. METHODS In a cross-sectional study during 7 years (2008-2014) on 50 untreated non recurrent non-metastatic newly diagnosed GISTs, molecular analysis and immunohistochemical staining for PDGFRA were performed and findings were compared with different clinicopathological characteristics.. RESULTS During the 7 years, 50 cases of GISTs according to the above mentioned criteria were found. 17 cases were negative for KIT mutation. Of them, 15 (30%) were positive for either exon 12 or 18 mutation of PDGFRA. These cases showed more epithelioid morphology and the number of mitotic figures were lower than PDFRA negative GISTs. Also according to the criteria for risk assessment, it seems that PDGFRA mutant GISTs are rarely in the high risk category. CONCLUSION PDGFRA mutant GISTs are common in Iranian population and it is recommended to perform mutation analysis for PDGFRA in every GIST with wild type KIT and epithelioid morphology. PMID- 27698974 TI - SpyGlass Pancreatoscopy and Successful Retrieval of a Proximally Migrated Pancreatic Stent; Unusual Case and Technical Tips. AB - Pancreatic stent proximal migration is a well known complication of pancreatic duct stenting, which occurs in about 5-6% of cases. Serious complications should be avoided by retrieval of the stent via different endoscopic techniques. We report a new technique previously reported only once (in a pancreatic duct with underlying pathology), to remove the proximally migrated pancreatic stent in a normal pancreatic duct by SpyGlass Direct Visualization System (Boston Scientific, Natick, Massachusetts, USA) and SpyBite Forceps (Boston Scientific, Natick, Massachusetts, USA). PMID- 27698975 TI - Upper Gastrointestinal Bleeding as the First Manifestation of Wegener's Granulomatosis. AB - Wegener's granulomatosis is an uncommon inflammatory disease that manifests as vasculitis, granulomatosis, and necrosis. It usually involves the upper and lower respiratory tracts and kidneys. Although it may essentially involve any organ, gastrointestinal (GI) involvement is notably uncommon. A 20-year-old male patient presented with epigastric pain, vomiting, hematemesis, and melena. On physical examination, he was pale. There was no abdominal tenderness or organomegaly. Upper GI endoscopy revealed dark blue-colored infiltrative lesions in prepyloric area. Evaluation of the biopsy sample showed mononuclear cell infiltration in the submucosal area, hyperplastic polyp, and chronic gastritis. High dose proton pump inhibitor and adjunctive supportive measures were given but no change in the follow-up endoscopy was detected. During hospital course, he developed intermittent fever and serum creatinine elevation. 12 days after admission, he developed dyspnea, tachypnea, and painful swelling of metacarpophalangeal joints, and maculopapular rash in extensor surface of the right forearm. Chest radiography showed pulmonary infiltration. Serum c-ANCA titer was strongly positive and skin biopsy revealed leukocytoclastic vasculitis. The patient received methylprednisolone pulse, which resulted in complete recovery of symptoms and gastric lesion. The present case indicates that GI bleeding may be the first manifestation of Wegener's granulomatosis. Moreover, it should be emphasized that gastric biopsy is not characteristic or diagnostic in such patients. PMID- 27698976 TI - Image Statistics and the Fine Lines of Material Perception. AB - We experience vivid percepts of objects and materials despite complexities in the way images are structured by the interaction of light with surface properties (3D shape, albedo, and gloss or specularity). Although the perception of gloss (and lightness) has been argued to depend on image statistics (e.g., sub-band skew), studies have shown that perceived gloss depends critically on the structure of luminance variations in images. Here, we found that separately adapting observers to either positive or negative skew generated declines in perceived gloss, contrary to the predictions of theories involving image statistics. We also found similar declines in perceived gloss following adaptation to contours geometrically correlated with sharp specular edges. We further found this aftereffect was stronger when contour adaptors were aligned with specular edges compared with adaptation to the same contours rotated by 90 degrees . These findings support the view that the perception of gloss depends critically on the visual system's ability to encode specular edge structure and not image skew. PMID- 27698977 TI - The Folded Paper Size Illusion: Evidence of Inability to Perceptually Integrate More Than One Geometrical Dimension. AB - The folded paper-size illusion is as easy to demonstrate as it is powerful in generating insights into perceptual processing: First take two A4 sheets of paper, one original sized, another halved by folding, then compare them in terms of area size by centering the halved sheet on the center of the original one! We perceive the larger sheet as far less than double (i.e., 100%) the size of the small one, typically only being about two thirds larger-this illusion is preserved by rotating the inner sheet and even by aligning it to one or two sides, but is dissolved by aligning both sheets to three sides, here documented by 88 participants' data. A potential explanation might be the general incapability of accurately comparing more than one geometrical dimension at once in everyday life, we solve this perceptual-cognitive bottleneck by reducing the complexity of such a task via aligning parts with same lengths. PMID- 27698978 TI - Do Individual Differences and Aging Effects in the Estimation of Geographical Slant Reflect Cognitive or Perceptual Effects? AB - Several individual differences including age have been suggested to affect the perception of slant. A cross-sectional study of outdoor hill estimation (N = 106) was analyzed using individual difference measures of age, experiential knowledge, fitness, personality traits, and sex. Of particular note, it was found that for participants who reported any experiential knowledge about slant, estimates decreased (i.e., became more accurate) as conscientiousness increased, suggesting that more conscientious individuals were more deliberate about taking their experiential knowledge (rather than perception) into account. Effects of fitness were limited to those without experiential knowledge, suggesting that they, too, may be cognitive rather than perceptual. The observed effects of age, which tended to produce lower, more accurate estimates of hill slant, provide more evidence that older adults do not see hills as steeper. The main effect of age was to lower slant estimates; such effects may be due to implicit experiential knowledge acquired over a lifetime. The results indicate the impact of cognitive, rather than perceptual factors on individual differences in slant estimation. PMID- 27698979 TI - Using Single Colors and Color Pairs to Communicate Basic Tastes. AB - Recently, it has been demonstrated that people associate each of the basic tastes (e.g., sweet, sour, bitter, and salty) with specific colors (e.g., red, green, black, and white). In the present study, we investigated whether pairs of colors (both associated with a particular taste or taste word) would give rise to stronger associations relative to pairs of colors that were associated with different tastes. We replicate the findings of previous studies highlighting the existence of a robust crossmodal correspondence between individual colors and basic tastes. However, while there was evidence that pairs of colors could indeed communicate taste information more consistently than single colors, our participants took more than twice as long to match the color pairs with tastes than the single colors. Possible reasons for these results are discussed. PMID- 27698980 TI - The Honeycomb illusion: Uniform textures not perceived as such. AB - We present a series of patterns, in which texture is perceived differently at fixation in comparison to the periphery, such that a physically uniform stimulus yields a nonuniform percept. We call this the Honeycomb illusion, and we discuss it in relation to the similar Extinction illusion (Ninio & Stevens, 2000). The effect remains strong despite multiple fixations, dynamic changes, and manipulations of the size of texture elements. We discuss the phenomenon in relation to how vision achieves a detailed and stable representation of the environment despite changes in retinal spatial resolution and dramatic changes across saccades. The Honeycomb illusion complements previous related observations in suggesting that this representation is not necessarily based on multiple fixations (i.e., memory) or on extrapolation from information available to central vision. PMID- 27698981 TI - The Perceived Size and Shape of Objects in Peripheral Vision. AB - Little is known about how we perceive the size and shape of objects in far peripheral vision. Observations made during an artistic study of visual space suggest that objects appear smaller and compressed in the periphery compared with central vision. To test this, we conducted three experiments. In Experiment 1, we asked participants to draw how a set of peripheral discs appeared when viewed peripherally without time or eye movement constraints. In Experiment 2, we used the method of constant stimuli to measure when a briefly presented peripheral stimulus appeared bigger or smaller compared with a central fixated one. In Experiment 3, we measured how accurate participants were in discriminating shapes presented briefly in the periphery. In Experiment 1, the peripheral discs were reported as appearing significantly smaller than the central disc, and as having an elliptical or polygonal contour. In Experiment 2, participants judged the size of peripheral discs as being significantly smaller when compared with the central disc across most of the peripheral field, and in Experiment 3, participants were quite accurate in reporting the shape of the peripheral object, except in the far periphery. Our results show that objects in the visual periphery are perceived as diminished in size when presented for long and brief exposures, suggesting diminution is an intrinsic feature of the structure of the visual space. Shape distortions, however, are reported only with longer exposures. PMID- 27698983 TI - Equidistant Intervals in Perspective Photographs and Paintings. AB - Human vision is extremely sensitive to equidistance of spatial intervals in the frontal plane. Thresholds for spatial equidistance have been extensively measured in bisecting tasks. Despite the vast number of studies, the informational basis for equidistance perception is unknown. There are three possible sources of information for spatial equidistance in pictures, namely, distances in the picture plane, in physical space, and visual space. For each source, equidistant intervals were computed for perspective photographs of walls and canals. Intervals appear equidistant if equidistance is defined in visual space. Equidistance was further investigated in paintings of perspective scenes. In appraisals of the perspective skill of painters, emphasis has been on accurate use of vanishing points. The current study investigated the skill of painters to depict equidistant intervals. Depicted rows of equidistant columns, tiles, tapestries, or trees were analyzed in 30 paintings and engravings. Computational analysis shows that from the middle ages until now, artists either represented equidistance in physical space or in a visual space of very limited depth. Among the painters and engravers who depict equidistance in a highly nonveridical visual space are renowned experts of linear perspective. PMID- 27698982 TI - Relative Visual Oscillation Can Facilitate Visually Induced Self-Motion Perception. AB - Adding simulated viewpoint jitter or oscillation to displays enhances visually induced illusions of self-motion (vection). The cause of this enhancement is yet to be fully understood. Here, we conducted psychophysical experiments to investigate the effects of different types of simulated oscillation on vertical vection. Observers viewed horizontally oscillating and nonoscillating optic flow fields simulating downward self-motion through an aperture. The aperture was visually simulated to be nearer to the observer and was stationary or oscillating in-phase or counter-phase to the direction of background horizontal oscillations of optic flow. Results showed that vection strength was modulated by the oscillation of the aperture relative to the background optic flow. Vertical vection strength increased as the relative oscillatory horizontal motion between the flow and the aperture increased. However, such increases in vection were only generated when the added oscillations were orthogonal to the principal direction of the optic flow pattern, and not when they occurred in the same direction. The oscillation effects observed in this investigation could not be explained by motion adaptation or different (motion parallax based) effects on depth perception. Instead, these results suggest that the oscillation advantage for vection depends on relative visual motion. PMID- 27698984 TI - How Beauty Determines Gaze! Facial Attractiveness and Gaze Duration in Images of Real World Scenes. AB - We showed that the looking time spent on faces is a valid covariate of beauty by testing the relation between facial attractiveness and gaze behavior. We presented natural scenes which always pictured two people, encompassing a wide range of facial attractiveness. Employing measurements of eye movements in a free viewing paradigm, we found a linear relation between facial attractiveness and gaze behavior: The more attractive the face, the longer and the more often it was looked at. In line with evolutionary approaches, the positive relation was particularly pronounced when participants viewed other sex faces. PMID- 27698985 TI - Touching and Hearing Unseen Objects: Multisensory Effects on Scene Recognition. AB - In three experiments, we investigated the influence of object-specific sounds on haptic scene recognition without vision. Blindfolded participants had to recognize, through touch, spatial scenes comprising six objects that were placed on a round platform. Critically, in half of the trials, object-specific sounds were played when objects were touched (bimodal condition), while sounds were turned off in the other half of the trials (unimodal condition). After first exploring the scene, two objects were swapped and the task was to report, which of the objects swapped positions. In Experiment 1, geometrical objects and simple sounds were used, while in Experiment 2, the objects comprised toy animals that were matched with semantically compatible animal sounds. In Experiment 3, we replicated Experiment 1, but now a tactile-auditory object identification task preceded the experiment in which the participants learned to identify the objects based on tactile and auditory input. For each experiment, the results revealed a significant performance increase only after the switch from bimodal to unimodal. Thus, it appears that the release of bimodal identification, from audio-tactile to tactile-only produces a benefit that is not achieved when having the reversed order in which sound was added after having experience with haptic-only. We conclude that task-related factors other than mere bimodal identification cause the facilitation when switching from bimodal to unimodal conditions. PMID- 27698987 TI - New Insights Into the Evolution of Color Terms or an Effect of Saturation? AB - Through their thorough investigation of the Hadza, a nonindustrialized language community in Tanzania, Lindsey and colleagues (2015) developed a new approach to understand the evolution of color terms. In the present commentary, I discuss the possibility that some of their results might be explained by the lacking control of saturation of their color stimuli. The saturation of colors plays an important yet widely neglected role in color naming. The additional analyses presented here suggest that the results on Hadzane color naming could be due to variations in saturation in the stimulus set rather than being evidence for universal constraints on color term evolution. PMID- 27698986 TI - Explicit Associative Learning and Memory in Synesthetes and Nonsynesthetes. AB - Most current theories regarding the development of synesthesia focus on cross modal neural connections and genetic underpinnings, but recent evidence has revitalized the potential role of associative learning. In the present study, we compared synesthetes' and controls' ability to explicitly learn shape-color pairings. Using a continuous measure of accuracy and multiple testing blocks, we found that synesthetes learned these pairings faster than controls. In a delayed retest, synesthetes outperformed controls, demonstrating enhanced long-term memory for shape-color associations. Following this retest, participants learned shuffled associations, and we found little evidence for group differences in subsequent learning ability. Overall, our findings support the hypothesis that synesthetes have exceptional associative learning abilities and further specify that this advantage pertains to the initial learning rate and long-term retention of associations. PMID- 27698988 TI - An Easy Way to Show Memory Color Effects. AB - This study proposes and evaluates a simple stimulus display that allows one to measure memory color effects (the effect of object knowledge and memory on color perception). The proposed approach is fast and easy and does not require running an extensive experiment. It shows that memory color effects are robust to minor variations due to a lack of color calibration. PMID- 27698989 TI - Rotating Squares Look Like Pincushions. AB - Rotating squares appeared to be distorted into pincushions with concave sides. These illusory shape changes were caused by a perceived compression along the curved path of motion. PMID- 27698990 TI - Pot/Lid Illusion. AB - A new everyday visual size illusion is presented-the Pot/Lid illusion. Observers choose an unduly large lid for a pot. We ask whether the optic slant of the pot brim would increase its apparent size or if vision underestimates the size of tilted lids. PMID- 27698992 TI - Motion-Driven Transparency and Opacity. AB - When two adjacent surfaces move in step, this can generate a sensation of transparency, even in the absence of intersections. Stopping the motion of one surface makes it look suddenly opaque. PMID- 27698993 TI - Detection of Sound Image Movement During Horizontal Head Rotation. AB - Movement detection for a virtual sound source was measured during the listener's horizontal head rotation. Listeners were instructed to do head rotation at a given speed. A trial consisted of two intervals. During an interval, a virtual sound source was presented 60 degrees to the right or left of the listener, who was instructed to rotate the head to face the sound image position. Then in one of a pair of intervals, the sound position was moved slightly in the middle of the rotation. Listeners were asked to judge the interval in a trial during which the sound stimuli moved. Results suggest that detection thresholds are higher when listeners do head rotation. Moreover, this effect was found to be independent of the rotation velocity. PMID- 27698991 TI - Early Visual Perception Potentiated by Object Affordances: Evidence From a Temporal Order Judgment Task. AB - Perceived objects automatically potentiate afforded action. Object affordances also facilitate perception of such objects, and this occurrence is known as the affordance effect. This study examined whether object affordances facilitate the initial visual processing stage, or perceptual entry processes, using the temporal order judgment task. The onset of the graspable (right-handled) coffee cup was perceived earlier than that of the less graspable (left-handled) cup for right-handed participants. The affordance effect was eliminated when the coffee cups were inverted, which presumably conveyed less affordance information. These results suggest that objects preattentively potentiate the perceptual entry processes in response to their affordances. PMID- 27698994 TI - Matching the Material of Transparent Objects: The Role of Background Distortions. AB - It has been proposed that the visual system is able to estimate the refractive index of thick transparent objects from background distortions caused by them. More specifically, it was hypothesized that this is done based on a mid-level cue, the distortion field, whose computation from the input requires comparing the part of the background seen through the object with the part visible in plain view. We test two predictions derived from this hypothesis: (a) scene variables that do not change the distortion field, for instance, the density of the background texture, should not systematically influence the subjects' settings in a material matching task. (b) The uncertainty of the estimates should increase sharply, if the part of the background texture in plain view is removed. Our results are not compatible with these two predictions but are completely in line with the alternative interpretation that the subjects maximized the similarity of the distorted background textures on the image level. Additional results indicate that subjects can take relations between the distorted and the undistorted background into account if this is encouraged by the experimental design, but they do this in a simplistic way that is inappropriate to estimate the refractive index. PMID- 27635226 TI - Multi-site tumor sampling (MSTS) improves the performance of histological detection of intratumor heterogeneity in clear cell renal cell carcinoma (CCRCC). AB - Current standard-of-care tumor sampling protocols for CCRCC (and other cancers) are not efficient at detecting intratumoural heterogeneity (ITH). We have demonstrated in silico that an alternative protocol, multi-site tumor sampling (MSTS) based upon the divide and conquer (DAC) algorithm, can significantly increase the efficiency of ITH detection without extra costs. Now we test this protocol on routine hematoxylin-eosin (HE) sections in a series of 38 CCRCC cases. MSTS was found to outperform traditional sampling when detecting either high grade (p=0.0136) or granular/eosinophilic cells (p=0.0114). We therefore propose that MSTS should be used in routine clinical practice. PMID- 27540468 TI - Computational analysis of perturbations in the post-fusion Dengue virus envelope protein highlights known epitopes and conserved residues in the Zika virus. AB - The dramatic transformation of the Zika virus (ZIKV) from a relatively unknown virus to a pathogen generating global-wide panic has exposed the dearth of detailed knowledge about this virus. Decades of research in the related Dengue virus (DENV), finally culminating in a vaccine registered for use in endemic regions (CYD-TDV) in three countries, provides key insights in developing strategies for tackling ZIKV, which has caused global panic to microcephaly and Guillain-Barre Syndrome. Dengue virus (DENV), a member of the family Flaviviridae, the causal agent of the self-limiting Dengue fever and the potentially fatal hemorrhagic fever/dengue shock syndrome, has been a scourge in tropical countries for many centuries. The recently solved structure of mature ZIKV (PDB ID:5IRE) has provided key insights into the structure of the envelope (E) and membrane (M) proteins, the primary target of neutralizing antibodies. The previously established MEPP methodology compares two conformations of the same protein and identifies residues with significant spatial and electrostatic perturbations. In the current work, MEPP analyzed the pre-and post-fusion DENV type 2 envelope (E) protein, and identified several known epitopes (His317, Tyr299, Glu26, Arg188, etc.) (MEPPitope). These residues are overwhelmingly conserved in ZIKV and all DENV serotypes, and also enumerates residue pairs that undergo significant polarity reversal. Characterization of alpha-helices in E proteins show that alpha1 is not conserved in the sequence space of ZIKV and DENV. Furthermore, perturbation of alpha1 in the post-fusion DENV structure includes a known epitope Asp215, a residue absent in the pre-fusion alpha1. A cationic beta-sheet in the GAG-binding domain that is stereochemically equivalent in ZIKV and all DENV serotypes is also highlighted due to a residue pair (Arg286 Arg288) that has a significant electrostatic polarity reversal upon fusion. Finally, two highly conserved residues (Thr32 and Thr40), with little emphasis in existing literature, are found to have significant electrostatic perturbation. Thus, a combination of different computational methods enable the rapid and rational detection of critical residues as epitopes in the search for an elusive therapy or vaccine that neutralizes multiple members of the Flaviviridae family. These secondary structures are conserved in the related Dengue virus (DENV), and possibly rationalize isolation techniques particle adsorption on magnetic beads coated with anionic polymers and anionic antiviral agents (viprolaxikine) for DENV. These amphipathic alpha-helices could enable design of molecules for inhibiting alpha-helix mediated protein-protein interactions. Finally, comparison of these secondary structures in proteins from related families illuminate subtle changes in the proteins that might render them ineffective to previously successful drugs and vaccines, which are difficult to identify by a simple sequence or structural alignment. Finally, conflicting results about residues that are involved in neutralizing a DENV-E protein by the potent antibody 5J7 (PDB ID:3J6U) are reported. PMID- 27698997 TI - Social autopsy of neonatal mortality suggests needed improvements in maternal and neonatal interventions in Balaka and Salima districts of Malawi. AB - BACKGROUND: The Every Newborn Action Plan calls for reducing the neonatal mortality rates to fewer than 10 deaths per 1000 live births in all countries by 2035. The current study aims to increase our understanding of the social and modifiable factors that can be addressed or reinforced to improve and accelerate the decline in neonatal mortality in Malawi. METHODS: The data come from the 2013 Verbal and Social Autopsy (VASA) study that collected data in order to describe the biological causes and the social determinants of deaths of children under 5 years of age in Balaka and Salima districts of Malawi. This paper analyses the social autopsy data of the neonatal deaths and presents results of a review of the coverage of key interventions along the continuum of normal maternal and newborn care and the description of breakdowns in the care provided for neonatal illnesses within the Pathway to Survival framework. RESULTS: A total of 320 neonatal deaths were confirmed from the VASA survey. While one antenatal care (ANC) visit was high at 94%, the recommended four ANC visits was much lower at 41% and just 17% of the mothers had their urines tested during the pregnancy. 173 (54%) mothers of the deceased newborns had at least one labor/delivery complication that began at home. The caregivers of 65% (n = 75) of the 180 newborns that were born at home or born and left a health facility alive perceived them to be severely ill at the onset of their illness, yet only 44% (n = 80) attempted and 36% (n = 65)could reach the first health provider after an average of 91 minutes travel time. Distance, lack of transport and cost emerged as the most important constraints to formal care-seeking during delivery and during the newborn fatal illness. CONCLUSIONS: This study suggests that maternal and neonatal health organizations and the local government of Malawi should increase the demand for key maternal and child health interventions, including the recommended 4 ANC visits, and ensure urine screening for all pregnant women. Early recognition and referrals of women with obstetric complications and interventions to promote maternal recognition of neonatal illnesses and care seeking before the child becomes severely ill are also needed to improve newborn survival in Balaka and Salima districts of Malawi. PMID- 27698998 TI - Self-reported diabetes education among Chinese middle-aged and older adults with diabetes. AB - BACKGROUND: To compare self-reported diabetes education among Chinese middle-aged and older adults with diabetes in three population groups: urban residents, migrants in urban settings, and rural residents. METHODS: We used data from the 2011 China Health and Retirement Longitudinal Study. The sample included 993 participants age 45 and older who reported having diabetes diagnosed from a health professional. We performed multilevel regressions performed to examine the associations between characteristics and different aspects of diabetes education received. FINDINGS: Our study shows that 20.24% of the participants received no diabetes education at all. Among those who received information, 46.82% of respondents with diabetes received weight control advice from a health care provider, 90.97% received advice on exercise, 60.37% received diet advice, 35.12% were spoken to smoking control, and only 17.89% of persons were informed of foot care. After controlling socioeconomic factors, life style, number of comorbidities and community factors, we found that compared with migrant population and rural residents, urban residents were more likely to receive diabetes education on diet. Urban residents were also more likely to obtain diabetes education and more aspects of diabetes education comparison with migrants and rural residents. CONCLUSIONS: Our study suggests diabetes education is a serious concern in China, and a significant proportion of the participants did not receive advice on smoking control and foot care. Rural residents and migrants from rural areas received much less diabetes education compared with urban residents. Efforts to improve diabetes educations are urgently needed in China. PMID- 27698999 TI - Population-level effectiveness of PMTCT Option A on early mother-to-child (MTCT) transmission of HIV in South Africa: implications for eliminating MTCT. AB - BACKGROUND: Eliminating mother-to-child transmission of HIV (EMTCT), defined as <=50 infant HIV infections per 100 000 live births, is a global priority. Since 2011 policies to prevent mother-to-child transmission of HIV (PMTCT) shifted from maternal antiretroviral (ARV) treatment or prophylaxis contingent on CD4 cell count to lifelong maternal ARV treatment (cART). We sought to measure progress with early (4-8 weeks postpartum) MTCT prevention and elimination, 2011-2013, at national and sub-national levels in South Africa, a high antenatal HIV prevalence setting ( ~ 29%), where early MTCT was 3.5% in 2010. METHODS: Two surveys were conducted (August 2011-March 2012 and October 2012-May 2013), in 580 health facilities, randomly selected after two-stage probability proportional to size sampling of facilities (the primary sampling unit), to provide valid national and sub-national-(provincial)-level estimates. Data collectors interviewed caregivers of eligible infants, reviewed patient-held charts, and collected infant dried blood spots (iDBS). Confirmed positive HIV enzyme immunoassay (EIA) and positive total HIV nucleic acid polymerase chain reaction (PCR) indicated infant HIV exposure or infection, respectively. Weighted survey analysis was conducted for each survey and for the pooled data. FINDINGS: National data from 10 106 and 9120 participants were analyzed (2011-12 and 2012-13 surveys respectively). Infant HIV exposure was 32.2% (95% confidence interval (CI) 30.7-33.6%), in 2011-12 and 33.1% (95% CI 31.8-34.4%), provincial range of 22.1-43.6% in 2012-13. MTCT was 2.7% (95% CI 2.1%-3.2%) in 2011-12 and 2.6% (95% CI 2.0-3.2%), provincial range of 1.9-5.4% in 2012-13. HIV-infected ARV-exposed mothers had significantly lower unadjusted early MTCT (2.0% [2011-12: 1.6-2.5%; 2012-13:1.5-2.6%]) compared to HIV-infected ARV-naive mothers [10.2% in 2011-12 (6.5-13.8%); 9.2% in 2012-13 (5.6-12.7%)]. Pooled analyses demonstrated significantly lower early MTCT among exclusive breastfeeding (EBF) mothers receiving >10 weeks ARV prophylaxis or cART compared with EBF and no ARVs: (2.2% [95% CI 1.25-3.09%] vs 12.2% [95% CI 4.7 19.6%], respectively); among HIV-infected ARV-exposed mothers, 24.9% (95% CI 23.5 26.3%) initiated cART during or before the first trimester, and their early MTCT was 1.2% (95% CI 0.6-1.7%). Extrapolating these data, assuming 32% EIA positivity and 2.6% or 1.2% MTCT, 832 and 384 infants per 100 000 live births were HIV infected, respectively. CONCLUSIONS: Although we demonstrate sustained national level PMTCT impact in a high HIV prevalence setting, results are far-removed from EMTCT targets. Reducing maternal HIV prevalence and treating all maternal HIV infection early are critical for further progress. PMID- 27699000 TI - Caregiver perceptions and utilization of oral rehydration solution and other treatments for diarrhea among young children in Burkina Faso. AB - BACKGROUND: More than 500 000 young children die from dehydration caused by severe diarrhea each year, globally. Although routine use of oral rehydration solution (ORS) could prevent almost all of these deaths, ORS utilization remains low in many low-income countries. Previous research has suggested that misperceptions among caregivers may be an obstacle to wider use of ORS. METHODS: To better understand the extent of ORS utilization and the reasons for use or non use in low-resource settings, the project team conducted a semi-structured, quantitative survey of 400 caregivers in Burkina Faso in 2014. All caregivers had a child below the age of five who had diarrhea lasting 2 days or more in the previous 2 months. RESULTS: Although more than 80% of caregivers were aware of ORS, less than half reported using it to treat their child's diarrhea. Replacing fluids lost due to diarrhea was considered a low priority by most caregivers, and many said they considered antibiotics more effective for treating diarrhea. Users and non-users of ORS held substantially different perceptions of the product, though all caregivers tended to follow recommendations of health care workers. A significant proportion of users reported difficulty in getting a child to drink ORS. Costs and access to ORS were not found to be significant barriers to use. CONCLUSIONS: Misperceptions among caregivers and health workers contribute to low utilization of ORS. Better caregiver understanding of diarrheal disease and the importance of rehydration, as well as increased recommendation by health workers, will help to increase ORS utilization. Improving product presentation and taste will also help to increase use. PMID- 27699001 TI - A study assessing postoperative Corrugate Rubber drain of perianal abscess. AB - BACKGROUND: Perianal abscess which can lead to a devastating complications. The management of perianal abscess involves incision and drainage by different methods one of them is packing the cavity. AIM OF THE STUDY: The aim is using Corrugate Rubber drain as an alternative to other methods. PATIENTS AND METHODS: This study was an observational retrospective review of 137 'case series' of patients with perianal abscess over a fifteen-year period from January 2000 to December 2015. 67 patients in group A were managed by Corrugated Rubber drain and 70 patients in group B were managed by packing. In group A, males were 92.53% more than females (7.46%) while group B, males were 85.71% and the rest were females. Outcome measures were assessed; time to cavity healing, pain scoring, abscess recurrence, fistula formation, analgesic requirement and skin disfigurement. RESULTS: The mean time of abscess healing in group A and B were 8.50 +/- 0.49 and 8.90 +/- 0.23 days respectively. Their pain score using Corrugate Rubber drain postoperative were 2/10 in group A while group B was 8/10. Most of patients in group A needed mild analgesia (52/67) (77.61%). The rate of abscess recurrence and fistula development were (22/67) (32.83%) and (21/67) (31.34%) respectively in group A which is significantly lower than group B. CONCLUSIONS: Management of perianal abscess using Corrugate Rubber drain in compares with packing leads to immediate pain relief, low recurrence rate of abscess and fistula formation, without need to expert nursing and less ugly scar formation. This resulted in low morbidity and cost. PMID- 27699002 TI - The impact of temporal artery biopsy on surgical practice. AB - BACKGROUND: Giant cell arteritis (GCA) has the potential to cause irreversible blindness and stroke in affected patients [1-4]. Temporal artery biopsy (TAB) remains the gold standard test for GCA [6-8]. Recent literature suggests that TAB does not change management of patients with suspected GCA and that ultrasound scan (USS) may be sufficient enough alone to confirm the diagnosis [9-11,13]. The aim of this study is to therefore determine the impact of TAB on current surgical practice and emergency theatre services. MATERIALS AND METHODS: A retrospective clinical study was performed of patients who had undergone TAB at the Caboolture Hospital from January 2010 to September 2015. Demographic and clinical data was collected from patient's medical records in regards to GCA. RESULTS: A total of 55 TAB were performed on 50 patients. Only two TAB were positive for GCA. Thirty eight (76%) patients had a pre-TAB ACR criteria score of >=3. Pre-operative corticosteroids were administered in forty-five (90%) patients, on average 4 +/- 10 days pre-TAB. Mean time to TAB was 1.6 +/- 1.6 days following their booking. Ninety-one percent of TAB were performed by surgical registrars. All TAB were performed using local anaesthesia alone. CONCLUSIONS: TAB is an expensive procedure with a low positive yield. Recent evidence suggests promising results with USS in diagnosing GCA. With the exceedingly low positive TAB results found in this study, patients with suspected GCA should be investigated in accordance with the above algorithm. The routine use of USS will reduce the number of negative TAB performed. PMID- 27699003 TI - Using electronic health record collected clinical variables to predict medical intensive care unit mortality. AB - BACKGROUND: Clinical decision support systems are used to help predict patient stability and mortality in the Intensive Care Unit (ICU). Accurate patient information can assist clinicians with patient management and in allocating finite resources. However, systems currently in common use have limited predictive value in the clinical setting. The increasing availability of Electronic Health Records (EHR) provides an opportunity to use medical information for more accurate patient stability and mortality prediction in the ICU. OBJECTIVE: Develop and evaluate an algorithm which more accurately predicts patient mortality in the ICU, using the correlations between widely available clinical variables from the EHR. METHODS: We have developed an algorithm, AutoTriage, which uses eight common clinical variables from the EHR to assign patient mortality risk scores. Each clinical variable produces a subscore, and combinations of two or three discretized clinical variables also produce subscores. A combination of weighted subscores produces the overall score. We validated the performance of this algorithm in a retrospective study on the MIMIC III medical ICU dataset. RESULTS: AutoTriage 12 h mortality prediction yields an Area Under Receiver Operating Characteristic value of 0.88 (95% confidence interval 0.86 to 0.88). At a sensitivity of 80%, AutoTriage maintains a specificity of 81% with a diagnostic odds ratio of 16.26. CONCLUSIONS: Through the multidimensional analysis of the correlations between eight common clinical variables, AutoTriage provides an improvement in the specificity and sensitivity of patient mortality prediction over existing prediction methods. PMID- 27699006 TI - Spiritual leadership at the workplace: Perspectives and theories. AB - Leadership has always been an area of interest since time immemorial. Nevertheless, scientific theories regarding leadership started to appear only from the beginning of the 20th century. Modern theories of leadership such as strategic leadership theory emerged as early as the 1980s when outdated theories of behavioral contingency were questioned, resulting in the beginning of a shift in focus leading to the emergence of modern theories hypothesizing the importance of vision, motivation and value-based control of clan and culture. Value-driven clan control emphasizes the importance of the role played by employees in a rapidly changing work environment. Therefore, the 21st century marked the rise of the need to establish a culture driven by values, inspiring the workforce to struggle and strongly seek a shared vision. This can be accomplished by an effective and motivating leadership. PMID- 27699004 TI - Emerging role of microRNA-21 in cancer. AB - MicroRNAs (miRs) are a class of single-stranded RNA molecules of 15-27 nucleotides in length that regulate gene expression at the post-translational level. miR-21 is one of the earliest identified cancer-promoting 'oncomiRs', targeting numerous tumor suppressor genes associated with proliferation, apoptosis and invasion. The regulation of miR-21 and its role in carcinogenesis have been extensively investigated. Recent studies have focused on the diagnostic and prognostic value of miR-21 as well as its implication in the drug resistance of human malignancies. The further use of miR-21 as a biomarker and target for cancer treatments is likely to improve the outcome for patients with cancer. The present review highlights recent findings associated with the importance of miR 21 in hematological and non-hematological malignancies. PMID- 27699005 TI - Calprotectin as a diagnostic tool for inflammatory bowel diseases. AB - Inflammatory bowel diseases (IBD) are chronic intestinal disorders caused by a number of factors, including external influences, intestinal microbiota and genetics. The two major clinically defined types of IBD are Crohn's disease and ulcerative colitis, each of which is characterized by relapses in the clinical course, thus patients must be under constant observation via regular endoscopies. As endoscopy, which has been used for direct evaluation and diagnosis of IBD, requires uncomfortable and expensive bowel preparation, a non-invasive test was required to reduce the number of patients undergoing unnecessary endoscopy. Calprotectin is a protein occurring in the cytosol of inflammatory cells and is released by the activation of leukocytes. As it is elevated and stable in the faeces of patients with IBD and can be reliably detected in faecal samples of <5 g, it may serve as an inexpensive, non-invasive diagnostic method for IBD. This is explored in the following review. PMID- 27699007 TI - Effects of antiepileptic drugs on the serum folate and vitamin B12 in various epileptic patients. AB - Epilepsy is a common neurodegenerative disease with an increasing morbidity. Clinical treatment of epilepsy includes symptomatic treatment, etiological treatment, surgery and prevention. The aim of the present study was to determine the effects of antiepileptic drugs (AEDs) on serum folate and vitamin B12 in various epileptic patients, and to examine the correlation between these effects and secondary cerebrovascular events. A total of 68 epileptic patients, diagnosed between May 2012 and May 2014, were included in the present study. The study included 8 cases of autonomic seizures, 10 cases of absence seizures, 13 cases of complex partial seizures, 28 cases of generalized tonic-clonic seizures, and 9 cases of simple partial seizures. The patients received appropriate AED treatment according to the characteristics of epileptic seizure and the treatment guidance. The differences in the serum levels of folate and vitamin B12 in these patients, and the differences in the secondary cerebrovascular events in these patients after 1 year follow-up were analyzed. The difference in the AEDs used by various epileptic patients was statistically significant (P<0.05). The proportion of AED monotherapy in the autonomic seizure group and petit mal group was highest, and the proportion of two AED in combination with the psychomotor seizure, grand mal and simple partial seizure groups was highest. The serum levels of folate and vitamin B12 in these patients following treatment were significantly lower than those prior to treatment (P<0.05). The differences in the serum levels of folate and vitamin B12 in these groups following treatment were not statistically significant (P>0.05). The difference in the incidence of cerebrovascular events in these groups at follow up was not statistically significant (P>0.05). The multifactorial logistic regression analysis revealed that the serum levels of folate and vitamin B12 were the independent risk factors for epilepsy with secondary cerebrovascular events [folate: odds ratio (OR)=0.536, P=0.039; vitamin: OR=0.382, P=0.041]. In conclusion, various AEDs may decrease the serum levels of folate and vitamin B12 and affect the secondary cerebrovascular events in various epileptic patients. Thus, regular supplementation of folate and vitamin B12 may be an option. PMID- 27699008 TI - Comparison of gene expression profiles in aortic dissection and normal human aortic tissues. AB - The aim of the present study was to compare the gene expression profiles in aortic dissection (AD) and healthy human aortic tissue samples by DNA microarray analysis in order to screen the differential genes. In total, five AD and four healthy aortic specimens were selected; the total RNA was extracted and reverse transcribed into cDNA and in vitro transcribed into aRNA, followed by microarray hybridization for analysis. Thereafter, the transcription levels of six differential genes, myosin light chain kinase (MYLK), polycystin 1, transient receptor potential channel interacting (PKD-1), myosin heavy chain 11 (MYH11), superoxide dismutase 3, extracellular (SOD3), filamin A (FLNA), and transgelin (TAGLN), screened from the expression profiles were quantitatively verified. Compared with the healthy aortic specimens, a total of 1,661 genes in the AD group demonstrated more than 2-fold differential expression, of which 997 genes were upregulated and 664 genes were downregulated. Thereafter, six AD-associated genes that showed downregulation in the microarray assay were selected for quantitatively verifying the gene transcription level using reverse transcription quantitative polymerase chain reaction (RT-qPCR), which confirmed their downregulation compared with the healthy aortic tissue genes; of the six genes, the expression levels of MYLK, PKD-1, MYH11, SOD3 and TAGLN were significantly downregulated (P<0.05), while the expression of FLNA was not significantly downregulated (P>0.05). Thus, whole genome microarray may be used to screen differentially expressed genes between AD and healthy aortic tissues. When used in combination with RT-qPCR validation, this method may provide novel strategies for investigating AD. PMID- 27699009 TI - Alcohol consumption and risk of subarachnoid hemorrhage: A meta-analysis of 14 observational studies. AB - The association between alcohol consumption and the risk of subarachnoid hemorrhage (SAH) is inconsistent. Thus, meta- and a dose-response analyses are presented with the purpose of assessing their associations. A systematic literature search was performed using Pubmed and Embase electronic databases for pertinent observational studies. Random-effects or fixed-effect models were employed to combine the estimates of the relative risks (RRs) with corresponding 95% confidence intervals (CIs). A dose-response pattern was conducted for further analysis. The current meta-analysis includes 14 observational studies reporting data on 483,553 individuals and 2,556 patients. The combined RRs of light alcohol consumption (<15 g/day) and moderate alcohol consumption (15-30 g/day) compared with teetotal individuals were 1.27 (95% CI: 0.95, 1.68) and 1.33 (95% CI: 0.84, 2.09), respectively, which indicated no significant association between light-to moderate alcohol consumption and SAH. An increased risk of SAH was noted in heavy alcohol consumption (>30 g/day) when compared with no alcohol consumption, as demonstrated by a result of 1.78 (95% CI: 1.46, 2.17). Dose-response analysis showed evidence of a linear association (P=0.0125) between alcohol consumption and SAH. The risk of SAH increased by 12.1% when alcohol consumption was increased by 10 g/day. Therefore, heavy alcohol consumption was found to be associated with an increased risk of SAH. Furthermore, the association between SAH and alcohol consumption has clinical relevance with regard to risk factor modification and the primary and secondary prevention of SAH.

AB - In the era of intensity-modulated radiotherapy, distant metastasis is currently the main cause of treatment failure for nasopharyngeal carcinoma (NPC). Additional therapeutic strategies are required to control the metastasis and improve survival. One strategy is targeted therapy, for example against c-Kit. In the current study, the frequency of c-Kit expression was determined immunohistochemically in 106 NPC patients. c-Kit expression changes during the course of radiation therapy were detected in 41 cases via weekly biopsy. Twelve cases (11.3%) had c-Kit expression scores of 3+ and 16 (15.1%) had scores of 2+. Thus, c-Kit overexpression (2+ or 3+) was observed in 28 (26.4%) patients. There were 35 (33.0%) and 43 (40.6%) patients with c-Kit expression scores of 1+ and 0, respectively. Furthermore, a trend of decreased c-Kit expression was observed after commencing radiotherapy according to the 41 NPC patients who were biopsied weekly. Therefore, c-Kit overexpression was identified to be common in NPC, and evaluating c-Kit as a therapeutic target for metastatic NPC via c-Kit overexpression subsequent to first line treatment may be of interest. To the best of our knowledge, the present study is the first to demonstrate a trend of decreased c-Kit expression during the course of radiotherapy. PMID- 27699011 TI - Effect of L-thyroxine treatment versus a placebo on serum lipid levels in patients with sub-clinical hypothyroidism. AB - Sub-clinical hypothyroidism is a common disease and whether L-thyroxine replacement treatment improves serum lipid levels in affected patients remains controversial. Thus, the aim of the present meta-analysis was to assess the effect of L-thyroxine therapy on serum lipid levels in sub-clinical hyperthyroidism. Relevant randomized controlled trials (RCTs) containing continuous data, published until July 2015 were retrieved from the Cochrane Library, PubMed, Medline, Google Scholar and Embase databases and subjected to meta-analysis using Review Manager software version 5.2 (The Nordic Cochrane Centre, Copenhagen, Denmark). Seven RCTs comprising 319 patients were included. The overall methodological quality of the RCTs was good. Statistical analysis revealed that serum low-density lipoprotein-cholesterol (LDL-C) levels were significantly decreased after L-thyroxine treatment [mean difference (MD): -0.23; 95% confidence interval: -0.44, -0.03; P=0.02], while changes of total cholesterol (TC), triglyceride (TG) and high-density lipoprotein-cholesterol (HDL C) were not significant (MD: -0.18, P=0.09; MD: -0.02, P=0.78; and MD: -0.06, P=0.14, respectively). In conclusion, the meta-analysis performed in the present study revealed that compared with placebo treatment, L-thyroxine significantly improved serum LDL-C levels in patients with sub-clinical hypothyroidism, while not significantly affecting TC, TG and HDL-C levels. PMID- 27699012 TI - Lipopolysaccharide-binding protein is efficient in biodosimetry during radiotherapy of lung cancer. AB - The aim of the present study was to determine if the serum levels of early markers of inflammation, such as interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-alpha), C-reactive protein (CRP), and lipopolysaccharide-binding protein (LBP) were correlated with the radiation dose received by the pulmonary and mediastinal structures of patients with non-small cell lung cancer (NSCLC). This pilot study included 26 patients with NSCLC who received total radiation doses ranging from 54 to 74 Gy (2.0 Gy/fraction). Cytokines were measured at baseline by enzyme-linked immunosorbant assay, and following administration of total doses of 20 and 40 Gy. A control group of 26 participants was sampled for comparisons with patient baseline cytokine levels. Only data from the 40-Gy cytokine blood levels of patients with NSCLC were identified to be correlated with histograms of the parameters of each patient's radiotherapy protocol. The IL 6, TNF-alpha and CRP median baseline levels of the patients with NSCLC were significantly higher than those of the controls (all P<=0.01). No differences were observed between the LBP levels of the patients and controls [median, 36.34 (25-75%; 31.35-39.27) vs. 36.92 (30.20-44.05) ug/ml, respectively; P=0.42]. No significant differences in the levels of the four cytokines between baseline, and at 20 and 40 Gy were observed [IL-6 (P=0.19); TNF-alpha (P=0.68); CRP (P=0.44) and LBP (P=0.29)]. LBP was significantly and positively correlated with the mean radiation dose to the lung (r=0.409; P=0.038), and showed a positive correlation with the percentage of lung volume exposed to at least 20 Gy of the planned radiation dose (r=0.3536; P=0.0764). CRP levels were positively correlated with the mean radiation dose to the esophagus (r=0.404; P=0.041); however, IL-6, TNF alpha and CRP were not significantly associated with other lung dosimetry parameters. Thus, LBP levels were correlated with radiation exposure of pulmonary tissues, and LBP may be a marker that warrants further investigation on radiotoxicity in NSCLC patients. PMID- 27699013 TI - FEN1 -69G>A and +4150G>T polymorphisms and breast cancer risk. AB - Flap endonuclease 1 (FEN1), a DNA repair protein, is important in preventing carcinogenesis. Two functional germ line variants -69G>A (rs174538) and +4150G>T (rs4246215) in the FEN1 gene have been associated with risk of various types of cancer. The aim of the present study was to evaluate the possible impact of FEN1 polymorphisms on risk of breast cancer (BC) in a sample of Iranian subjects. The FEN1 -69G>A and +4150G>T polymorphisms were analyzed in a case-control study that included 266 BC patients and 225 healthy females. Polymerase chain reaction restriction fragment length polymorphism analysis was used to genotype the variants. The findings demonstrated that the FEN1 -69G>A and +4150G>T polymorphisms were not associated with BC risk in co-dominant, dominant and recessive inheritance models. The findings indicated that GG/GT, GA/GG and GA/TT genotypes significantly decreased the risk of BC when compared with 69GG/+4150GG. Furthermore, haplotype analysis indicated that -69G/+4150T as well as -69A/+4150G significantly decreased the risk of BC compared with -69G/+4150G. Thus, these findings demonstrated that haplotypes of FEN1 -69G>A and +4150G>T polymorphisms decreased the risk of BC in an Iranian population. Further studies with larger sample sizes and different ethnicities are required to validate the present findings. PMID- 27699014 TI - Analysis of the add-on effect of alpha-glucosidase inhibitor, acarbose in insulin therapy: A pilot study. AB - The aim of the present study was to evaluate the add-on effect of acarbose therapy in oxidative stress, and the lipid and inflammatory profiles of patients with type 2 diabetes mellitus (T2DM) treated with insulin. This was an open and unblended study. Patients (n=134) with T2DM (haemoglobin A1c range, 9.0-12.0%) were recruited. After continuous subcutaneous insulin infusion for 7 days for initial rapid correction of hyperglycaemia, a premixed insulin titration period (duration, 4-6 days) subsequently followed. Patients were then randomized (1:1) into two groups as follows: An acarbose plus pre-mixed 30/70 insulin group or a pre-mixed 30/70 insulin only group; each group received treatment for 2 weeks. Plasma high-sensitivity C-reactive protein (Hs-CRP), 8-iso-prostaglandin F2alpha (8-iso PGF2alpha), tumor necrosis factor-alpha (TNF-alpha), interleukin (IL) 1beta, and IL-6 levels were measured before and after therapy. Patients that received acarbose plus insulin demonstrated greater reduction in 8-iso PGF2alpha, Hs-CRP, TNF-alpha, IL-1beta and IL-6 levels when compared with the insulin only patients. Thus, acarbose add-on insulin therapy was identified to be associated with greater improvements in oxidative stress and inflammation in patients with T2DM when compared with those that received insulin only therapy. PMID- 27699015 TI - Association of DNA methyltransferase polymorphisms with susceptibility to primary gouty arthritis. AB - Gouty arthritis is the most common type of inflammatory and immune disease, and the prevalence and incidence of gout increases annually. Genetic variations in the DNA methyltransferases (DNMTs) gene have not, to the best of our knowledge, been reported to influence gene expression and to participate in the pathogenesis of gout. The aim of the present study was to investigate whether the DNMT1, DNMT3A and DNMT3B polymorphisms contribute to gout susceptibility. These polymorphisms were screened for in 336 gout patients and 306 healthy control subjects (from a South China population) for association with gout. The distribution frequencies of DNMT1 rs2228611 AA genotype (P=0.007) and A allele (P=0.002; odds ratio=1.508, 95% confidence interval=1.158-1.964) were found to be significantly increased in the gout patients when compared with those in the healthy control subjects. The rs1550117 in DNMT3A and rs2424913 in DNMT3B exhibited no significant associations with gout susceptibility between the patients and control subjects. These results demonstrated that the DNMT1 rs2228611 polymorphism may be involved in the pathogenesis of gout, while DNMT3A rs1550117 and DNMT3B rs2424913 did not show any obvious significance in the current study; thus, may not be used as risk factors to predict the susceptibility to gout. However, further studies are required to investigate the functions and regulatory mechanism of the polymorphisms of DNMTs in gout. PMID- 27699016 TI - Resistin-induced cardiomyocyte hypertrophy is inhibited by apelin through the inactivation of extracellular signal-regulated kinase signaling pathway in H9c2 embryonic rat cardiomyocytes. AB - It has been reported that resistin induces, whereas apelin inhibits cardiac hypertrophy. However, the underlying molecular mechanisms of apelin inhibiting resistin-induced cardiac hypertrophy remain unclear. The aim of the current study is to investigate the effects of apelin on resistin-induced cardiomyocyte hypertrophy and elucidate the underlying molecular mechanism. H9c2 cells were used in the present study, and cell surface area and protein synthesis were evaluated. Reverse transcription-quantitative polymerase chain reaction was performed to analyze the expression levels of hypertrophic markers, brain natriuretic peptide (BNP) and beta-myosin heavy chain (beta-MHC). In addition, western blotting was conducted to examine phosphorylation of extracellular signal regulated kinase (ERK)1/2. Following treatment of H9c2 cells with resistin, cell surface area, protein synthesis, and BNP and beta-MHC mRNA expression levels were increased. Subsequent to co-treatment of H9c2 cells with apelin and resistin, lead to the inhibition of resistin-induced hypertrophic effects by apelin. In addition, treatment with resistin increased phosphorylation of ERK1/2, whereas pretreatment with apelin decreased phosphorylation of ERK1/2, which was increased by resistin. These results indicate that resistin-induced cardiac hypertrophy is inhibited by apelin via inactivation of ERK1/2 cell signaling. PMID- 27699017 TI - Change ratio of hemoglobin has predictive value for upper gastrointestinal bleeding. AB - The present study aimed to identify novel predictors of upper gastrointestinal (GI) bleeding by assessing change ratios of blood test variables. Records of 1,023 patients (431 men and 592 women) who underwent endoscopy between October 2014 and September 2015 at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) were retrospectively analyzed. Patients whose blood test variables for the time-point of endoscopy and three months previously were available were enrolled and subsequently categorized into a group with and another one without upper GI bleeding (n=32 and 84, respectively), and the respective change ratios were calculated for each group. One-way analysis of variance revealed that in patients with upper GI bleeding, change ratios of white blood cell count and alkaline phosphatase were significantly higher than those in patients without, while change ratios of hemoglobin (Hb), total protein and albumin were significantly reduced. Logistic regression analysis demonstrated that the change ratio of Hb was significantly correlated with upper GI bleeding. Receiver-operator characteristic analysis revealed that an 18.7% reduction of Hb was the threshold value for the prediction of upper GI bleeding. In conclusion, the present study revealed that a >=18.7% reduction in Hb over three months has predictive value for upper GI bleeding. PMID- 27699018 TI - Early prophylactic anticoagulation for portal vein system thrombosis after splenectomy: A systematic review and meta-analysis. AB - A systematic review and meta-analysis were conducted to evaluate the efficacy and safety of early prophylactic anticoagulation for the prevention of portal vein system thrombosis (PVST) after splenectomy. A systematic search of the PubMed, EMBASE, Springer and Cochrane Library databases was performed to identify studies comparing the outcomes in patients receiving or not receiving regular prophylactic anticoagulation after splenectomy. The quality of the included studies was assessed using the Jadad Score and the Newcastle-Ottawa Scale. Heterogeneity was evaluated using the chi2 and I2 tests. The parameters that were analyzed included the incidence of PVST and anticoagulation-associated complications. A total of seven studies qualified for the review, involving 383 and 283 patients receiving or not receiving regular prophylactic anticoagulation, respectively. The incidence of PVST was significantly reduced with an odds ratio (OR) of 0.31 [95% confidence interval (CI), 0.21-0.46; P<0.00001] in the regular prophylactic anticoagulation group compared with the control group. No difference in the incidence of anticoagulation-associated complications was identified between the two groups (OR=0.60, 95% CI, 0.23-1.56; P=0.30). Early prophylactic anticoagulation was associated with a reduced incidence of PVST, although it was not associated with the incidence of anticoagulation-associated complications. These results indicate that prophylactic anticoagulation could be safely administered after splenectomy, even to cirrhotic patients. PMID- 27699019 TI - Mechanisms of simvastatin-induced vasodilatation of rat superior mesenteric arteries. AB - Independent of its lipid-lowering properties, simvastatin (Sim) induces vasorelaxation; however, the underlying mechanisms have remained elusive. The aim of the present study was to investigate the vasorelaxant effects of Sim on rat superior mesenteric arteries and the mechanisms involved. The isometric tension of rat superior mesenteric arterial rings was recorded in vitro on a myograph. The results showed that Sim concentration-dependently relaxed the superior mesenteric artery rings with endothelium pre-contracted by phenylephrine hydrochloride [maximum relaxation (Emax)=51.05+/-4.09%; negative logarithm of the concentration that caused 50% of the maximum response (pD2)=4.17+/-0.18] or KCl (Emax=41.65+/-1.32%; pD2=3.55+/-0.1). Nomega-nitro-L-arginine methyl ester (100 uM) significantly inhibited this effect, while it was not affected by 1H [1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one (10 uM) and indomethacin (5 uM). In artery rings without endothelium, vasorelaxation induced by Sim was attenuated by 4-aminopyridine (100 uM), but was not affected by barium chloride dehydrate (10 uM), glibenclamide (10 uM) and traethylammonium chloride (1 mM). Moreover, Sim also inhibited the contraction induced by increasing external calcium in Ca2+ free medium with added KCl (60 mM). These results suggested that Sim induces relaxation of superior mesenteric arterial rings through an endothelium-dependent pathway, involving nitric oxide release and also through an endothelium independent pathway, involving the opening of voltage-dependent K+ channels and blockade of extracellular Ca2+ influx. PMID- 27699020 TI - Efficacy of daiokanzoto in chronic constipation refractory to first-line laxatives. AB - There are only a few treatment options for constipation and limited evidence of suitable treatments. Daiokanzoto (DKT) is a Kampo medicine often used clincally to treat constipation. DKT is a laxative used predominantly in Japan; however, clinical data on its efficacy and safety is lacking. Patients who used DKT, but were intolerant to either magnesium oxide (MgO; MgO group; n=16) or senna extract (Senna group; n=26) were included in the present study. The frequencies of their bowel movements were compared during the 1 week prior to and following DKT administration. Within 24 hours after DKT administration, 93.8% of the patients in the MgO group evacuated their bowels. The median bowel movement frequency 1 week prior to DKT administration was 2.5 and 1 week after DKT administration was significantly increased to 7.5. In the Senna group, within 24 h of DKT administration, 80.8% of the patients evacuated their bowels. The median bowel movement frequency 1 week prior to the DKT treatment was 2.0, which significantly increased to 8.5 1 week after the administration of DKT. The adverse events from DKT treatment were mild and controllable. PMID- 27699021 TI - A model for predicting nosocomial carbapenem-resistant Klebsiella pneumoniae infection. AB - Mortality associated with infections due to carbapenem-resistant Klebsiella pneumoniae (CR-KP) is high and the infections need to be predicted early. The risk factors for CR-KP infection are heterogeneous. The aim of the present study was to construct a model allowing for the early prediction of CR-KP infection. Nosocomial infections due to K. pneumoniae were evaluated retrospectively over a 2-year period. The case cohort consisted of 370 inpatients with CR-KP infection. For each case enrolled, two matched controls with no CR-KP infection during their hospitalization were randomly selected. Matching involved month of admission, ward, as well as interval days. The Vitek 2 system was used for identification of isolates and antimicrobial susceptibility testing. General linear model with logistic regression was used to identify possible risk factors. The predicted power of the model was expressed as the area under the receiver-operating characteristic curve. Age, male gender, with cardiovascular disease, hospital stay, recent admission to intensive care unit, indwelling urinary catheter, mechanical ventilation, recent beta-lactam-beta-lactamase inhibitors, fourth generation cephalosporins and/or carbapenems therapy were independent risk factors for CR-KP infection. Models predicting CR-KP infection developed by cumulative risk factors exhibited good power, with areas under the receiver operating characteristic curves of 0.902 [95% confidence interval (CI), 0.883 0.920; P<0.001] and 0.899 (95% CI, 0.877-0.921; P<0.001) after filtering by age (>=70 years). The Yonden index was at the maximum when the cumulative risk factors were >=3 in the two prediction models. The results show that the prediction model developed in the present study might be useful for controlling infections caused by CR-KP strains. PMID- 27699022 TI - Transcription factor 4 gene rs9960767 polymorphism in bipolar disorder. AB - The transcription factor 4 (TCF4) gene encodes a helix-loop-helix transcription factor protein, which initiates neuronal differentiation and is primarily expressed during nervous system development. The aim of the present study is to investigate the association of the TCF4 rs9960767 polymorphism and bipolar disorder, which is highly heritable. DNA isolation was performed on 95 patients with bipolar disorder and 108 healthy control subjects to examine the TCF4 rs9960767 polymorphism. Genotypic and allelic frequencies were determined using the polymerase chain reaction-restriction fragment length polymorphism method designed in our laboratory. Statistical analysis was performed using chi2 test within the 95% confidence interval. Odds ratios were calculated and Hardy Weinberg equilibrium (HWE) was verified for all control subjects and patients. The A allele frequency was 95.8% in the patients and 94.4% in the control subjects, and 4.2% in the patients and 5.6% in the control subjects for the C allele. The genotype frequencies of the TCF4 gene rs9960767 variant were as follows: AA, 91.6% and AC, 8.4% in patients with bipolar (CC genotype was not observed in cases); AA, 89.8%; AC, 9.3% and CC, 0.9% in the control subjects. No statistically significant difference was identified between the patients and control subjects (chi2=0.937; P=0.626). In addition, gender specific analysis was performed, although no significant association was found according to the gender distrubition. All patients and control subjects were in HWE (P>0.05). Statistical analysis of the data indicates that the TCF4 gene rs9960767 polymorphism is not an independent risk factor for bipolar disorder in the overall population or in terms of gender; however, an increased population size would improve the statistical power. Furthermore, additional gene variants that are specifically involved in neuronal development may be analyzed for revealing the complex genetic architecture of bipolar disorder. An improved approach would be better to evaluate the TCF4 gene in a pathway specific manner due to its role as a transcription factor. PMID- 27699023 TI - Elevated serum levels of two anti-neutrophil cytoplasmic antibodies in a lung cancer patient: A case report. AB - A 71-year-old woman with arthralgia and lung fibrosis was referred to Mito Kyodo General Hospital (Mito, Japan) for a mass, which was incidentally observed on a chest radiograph. The chest computed tomography scan demonstrated fibrotic lesions in the lower lobes of the lung and a nodule in the left upper lobe. The serum levels of myeloperoxidase (MPO)-anti-neutrophil cytoplasmic antibody (ANCA) and proteinase 3 (PR3)-ANCA were 60.3 and 7.5 U/ml, respectively. A transbronchial biopsy obtained from the nodule in the left upper lobe of the lung revealed a lung adenocarcinoma and the patient underwent standard upper lobectomy of the left lung. Subsequent to the resection, the serum levels of PR3-ANCA and MPO-ANCA returned to 10.0 and <1.0 U/ml, respectively. Notably, titers of antinuclear antibodies were also decreased during the postoperative course. Although elevated serum ANCA levels are rarely seen in lung cancer, they may be associated with the occurrence of lung cancer in certain patients, as observed in the present case. PMID- 27699024 TI - Intratumoral hemorrhage-related differences in the expression of vascular endothelial growth factor, basic fibroblast growth factor and thioredoxin reductase 1 in human glioblastoma. AB - The present study was designed to evaluate the expression of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF) and thioredoxin reductase 1 (TrxR1) in glioblastoma multiforme (GBM) with and without intratumoral hemorrhage. Surgically resected human GBM samples from 20 patients who underwent surgery at our institute were extracted from the histopathological specimens and divided into two groups. A total of 10 samples from each type of GBM (World Health Organization grade IV, intratumoral hemorrhage-positive or negative) were included in each group. VEGF, bFGF and TrxR1 expression was analyzed using immunohistochemistry and the results were compared between groups. VEGF and bFGF immunoreactivity was significantly higher in GBMs containing intratumoral hemorrhage. Furthermore, VEGF, bFGF and TrxR1 immunointensity was significantly higher in GBMs containing intratumoral hemorrhage. Thus, the present study demonstrated a higher VEGF, bFGF and TrxR1 expression in GBMs contain intratumoral hemorrhage, indicatiogn a role of VEGF, bFGF and TrxR1 expression in the promotion of tumoral angiogenesis and tumoral growth by complex mechanisms that require further elucidation. PMID- 27699025 TI - Allogeneic stem cell transplantation in a blast-phase chronic myeloid leukemia patient with carbapenem-resistant Klebsiella pneumoniae tricuspid valve endocarditis: A case report. AB - In chronic myeloid leukemia (CML), the occurrence of blastic transformation is rare. Treatment outcome is generally poor. Allogeneic stem cell transplantation (allo-SCT) is the only potentially curative treatment option for advanced-phase CML. Infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) isolates are associated with high morbidity and mortality rates, particularly in patients with haematological malignancies. Infection and colonization by these multiresistant bacteria may represent a challenge in SCT recipients for the management of post-transplantation complications, as well as for the eligibility to receive a transplant in patients who acquire the pathogen prior to the procedure. We herein report the case of a blast-phase CML patient with a highly resistant, CRKP-associated tricuspid valve endocarditis, who was treated with a combination of systemic antimicrobial therapy and surgical valve repair, and subsequently underwent a successful allo-SCT. PMID- 27699026 TI - Clinical and imaging characteristics of 53 ulcers of post-radiation nasopharyngeal necrosis in patients with nasopharyngeal carcinoma. AB - It is widely accepted that a mucosal ulcer induced by radiation (RIMU) is the predominant type of post-radiation nasopharyngeal ulcer in patients with nasopharyngeal carcinoma (NPC) who underwent radiotherapy (RT); however, another type of ulcer, an ulcer of post-radiation nasopharyngeal necrosis (UPRNN), has rarely been reported for patients with NPC. In the present study, the clinical and imaging features of 53 patients who were treated at the Zhejiang Provincial Cancer Center (Zhejiang Cancer Hospital, Hangzhou, China) between March 2009 and December 2015, and who were diagnosed with UPRNN, were reviewed. The clinical factors, laboratory examinations, magnetic resonance imaging (MRI) features and endoscopic findings were analysed. A UPRNN has its characteristic imaging features and ulcer locations at the primary tumour bed, which are different from a traditional RIMU. In the retrospective analysis of the clinical factors, a tumour (T) 3/4 stage, with invasion of muscular tissue, poor response of neoadjuvant chemotherapy and anaemia during the RT, may be associated with the occurrence of a UPRNN. To evaluate the severity, a UPRNN was divided into three grades according to the invasion depth of the ulcer based on its appearance in MRI, and the subsequent treatment and prognosis varied according to the severity of the UPRNN. In conclusion, a UPRNN has its clinical features and characteristic MRI appearances, and the occurrence of a UPRNN may be associated with several clinical factors. PMID- 27699027 TI - Replacement of the tumor bed following oncoplastic breast-conserving surgery with immediate latissimus dorsi mini-flap. AB - The aim of the present study was to evaluate the geographic variability of the tumor bed following oncoplastic breast-conserving surgery (OP-BCS), and to assess its relevance for radiotherapy planning. In this prospective study, pre- and postoperative computerized tomography (CT) scans of 22 patients with early-stage breast cancer were fused. The preoperative gross tumor volume or excisional biopsy cavity were contoured under the guidance of preoperative radiological images. Postoperative lumpectomy cavities were contoured under the guidance of surgical clips. The conformity index (CI) was calculated and defined on a scale between 0 and 1, where 0 indicated no overlap and 1 indicated 100% concordance. Associations between CI and the number of clips, time interval between surgery and CT scans, pathological tumor size and age were assessed using independent sample testing. The median CI was 0.07 (in five cases, 1, and in eight cases, 0). The lumpectomy cavity shifted from the primary location in 36.4% of the cases. Median shifts between the isocenters of pre- and postoperative volumes were measured as 1.02 cm (range, 0.4-4.43 cm) in the x, 1.07 cm (range, 0.05-5.67 cm) in the y, and 1.12 cm (range, 0-3.75 cm) in the z directions. Only the clip number was determined to be significantly associated with CI (P=0.017). Pre- and postoperative tumor bed volumes were fully superposed in five of the 22 cases. The present study has shown that the tumor bed is markedly replaced following OP BCS with latissimus dorsi mini-flap (LDMF) reconstruction. Special care should therefore be taken when defining the lumpectomy cavity following OP-BCS with LDMF reconstruction. PMID- 27699028 TI - Expression of the glucocorticoid receptor in breast cancer-associated fibroblasts. AB - Cancer- associated fibroblasts (CAFs) are actively involved in breast carcinoma. Our previous study demonstrated that the majority of these CAFs were smooth muscle actin (SMA) positive and were therefore termed peritumoral myofibroblast (PMY). Glucocorticoid, linked or not with its receptor (GR), has been postulated to serve a major role in normal breast and breast carcinoma; however, their role in CAFs remains poorly understood. The aim of the present study was to assess the presence of GR in breast CAFs and particularly in PMY in 56 cases of invasive breast carcinoma in correlation with clinicopathological parameters, by immunohistochemistry. GR was observed in CAFs in 51 cases (91%) and were more frequent in luminal A subtype (19/19 cases; 100%). The stromal expression was statistically correlated with the tumor grade (P=0.03), the Ki-67 index (P=0.003) and the presence of GR in the epithelial component (P=0.01). The demonstration of a frequent expression of GR in breast CAFs may serve as an interesting target for future therapeutics for the regulation of the tumoral breast microenvironment. PMID- 27699029 TI - Polaprezinc protects normal intestinal epithelium against exposure to ionizing radiation in mice. AB - Polaprezinc (PZ), an antiulcer drug, has been reported to have antioxidant effects. The purpose of the present study was to assess the radioprotective effects of PZ in the normal intestine of C57BL/6J mice. PZ was orally administered at 100 mg/kg body weight in the drinking water. Firstly, the present study compared the survival of normal intestinal crypt epithelial cells with mice that received PZ prior to or following irradiation. Next, the present study examined the sequential changes of the incidence of apoptosis in the normal intestine of mice that received irradiation. The mice that received PZ prior to irradiation demonstrated a stronger protective effect on the normal intestine compared with those that received PZ after irradiation. The present study therefore administrated PZ 2 h before irradiation in the subsequent experiments. The mice receiving PZ developed fewer apoptotic cells in the duodenum, jejunum and ileum. Radiation-induced cell death occurred with a peak at position 10 or lower from the base of the crypt axis, and was subsequently reduced by PZ treatment. Pretreatment with PZ protected the normal intestinal tissues from radiation-induced apoptosis. PMID- 27699030 TI - Chemotherapy-induced fatal hepatitis B virus reactivation in a small-cell lung cancer patient. AB - Hepatitis B virus (HBV) reactivation during chemotherapy is a major concern and is widely reported, particularly in association with hematological malignancies and lymphomas. While lung cancer ranks first in incidence and mortality worldwide, HBV reactivation has been largely overlooked in this disease. As regards small-cell lung cancer (SCLC), HBV reactivation has rarely been reported. We herein report the case of a hepatitis B surface antigen-seropositive SCLC patient in whom HBV was reactivated during the course of chemotherapy, despite preemptive use of lamivudine. The patient developed fulminant viral hepatitis and succumbed to liver failure. The aim of this report was to highlight the major but overlooked issue of HBV reactivation in SCLC, and suggest that agents more potent than lamivudine may be more efficacious in high-risk patients. PMID- 27699031 TI - Outpatient management without initial assessment for febrile patients undergoing adjuvant chemotherapy for breast cancer. AB - The purpose of this study was to retrospectively analyze the feasibility of outpatient management without initial assessment for febrile patients undergoing adjuvant chemotherapy for breast cancer. A total of 131 consecutive patients with breast cancer treated with adjuvant or neoadjuvant chemotherapy from 2011 to 2013 at Osaka Medical College Hospital (Osaka, Japan) were retrospectively reviewed. In the case of developing a fever (body temperature, >=38 degrees C), the outpatients had been instructed to take previously prescribed oral antibiotics for 3 days without any initial assessment, and if no improvement had occurred by then, they were required to visit the hospital for examination and to undergo treatment based on the results of a risk assessment for complications. The primary aim of the present study was to assess the outcome of febrile episodes, while the secondary aim was to assess the incidence of febrile episodes, hospitalizations, and the type of chemotherapy. The 131 patients received 840 chemotherapy administrations. Fifty-five patients (42.0%) had a total of 75 febrile episodes after 840 chemotherapy administrations (8.9%). Treatment failure occurred in 12 of the 75 episodes (16.0%) in 11 of the 55 patients (20.0%). Only four episodes required hospitalization. Treatment success was achieved in 63 episodes (84.0%). In conclusion, the feasibility of outpatient management without initial assessment was evaluated in the present study for febrile patients undergoing adjuvant chemotherapy for breast cancer, and the outpatient strategy regimen may be safe and convenient for these patients. PMID- 27699032 TI - Efficacy and safety of oxaliplatin, bevacizumab and oral S-1 for advanced recurrent colorectal cancer. AB - The aim of this study was to evaluate the efficacy and safety of co administration of oral S-1 and oxaliplatin (SOX) in combination with bevacizumab (bev) in patients with advanced recurrent colorectal cancer. A retrospective study of 36 patients with advanced recurrent colorectal cancer was performed, of whom 27 received first-line and 9 received second-line SOX+bev chemotherapy between 2010 and 2013 at the Hachioji Digestive Disease Hospital (Hachioji, Japan). The SOX+bev regimen consisted of administration of intravenous oxaliplatin (85 mg/m2) on days 1 and 14, bevacizumab (5 mg/kg) on day 1, and co administration of oral S-1 twice daily on days 1-14. The drug regimen was repeated every 4 weeks. SOX+bev treatment was associated with a response rate of 45.2%, a disease control rate of 71%, and a median progression-free survival (PFS) and overall survival (OS) of 9.9 and 21.9 months, respectively. Patients who received first-line chemotherapy benefited from treatment in terms of prolonged PFS (13.8 months) and OS (28.2 months). Grade 3/4 adverse events were infrequent and included anaemia, thrombocytopenia, anorexia, diarrhea, sensory neuropathy, increased aspartate aminotransferase level and skin rash. In conclusion, SOX+bev therapy was found to be feasible and safe for patients with advanced and recurrent colorectal cancer. PMID- 27699033 TI - Effect of ARID1A/BAF250a expression on carcinogenesis and clinicopathological factors in pure-type clear cell adenocarcinoma of the ovary. AB - Frequent mutation of the ARID1A gene has been recently identified in ovarian clear-cell adenocarcinoma (CCA); however, the clinical significance of BAF250a expression encoded by the ARID1A gene remains to be determined. The aim of the present study was to assess whether BAF250a expression had an impact on the clinical features of CCA. A total of 97 cases of CCA treated at a single institution were enrolled in the present study. The tissue samples were evaluated by immunohistochemical staining. BAF250a-deficient expression was observed in 30% (29/97) of all CCA cases. Of this, 19% of non-atypical endometriosis, 26% of atypical endometriosis, 39% of endometriosis-related CCA, 5% of benign clear-cell adenofibroma (CCAF), 5% of borderline CCAF and 10% of CCAF-related CCA. BAF250a deficient expression was significantly more frequent in endometriosis-related CCA compared with that in CCAF-related CCA (P=0.02). No significant difference was observed in the response rate of primary chemotherapy according to BAF250a expression status (P=0.48). Additionally, BAF250a expression status was not significantly correlated with progression-free and overall survival in patients with CCA. Although loss of BAF250a expression was associated with early tumorigenesis in endometriosis-related CCA, this alteration was not significantly correlated with chemosensitivity and prognoses of CCA. Further biomarker analyses, including BAF250a expression, are required to improve the prognoses of CCA. PMID- 27699034 TI - Analysis of blood neutrophil elastase, glutathione levels and pathological findings in postoperative acute exacerbation of idiopathic pulmonary fibrosis associated with lung cancer: Two case reports. AB - Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) is characterized by severe worsening dyspnea and high mortality. It has been proven that the serum neutrophil elastase (NE) level, in addition to the serum Krebs von den Lungen-6 (KL-6) and surfactant protein-D (SP-D) levels, was elevated in patients with IPF AE. Glutathione (GSH) is the major antioxidant involved in cell metabolism and survival. It is also known that IPF is characterized by reduced GSH levels in bronchoalveolar lavage fluid and blood. Case 1 was a 67-year-old man who was referred to our hospital complaining of a 2-year history of progressive dyspnea on exertion (DOE). The patient was initially diagnosed with IPF, followed by inhaled N-acetylcysteine monotherapy. Two years later, left upper lobectomy with lymph node dissection was performed due to primary lung cancer, which was large cell neuroendocrine carcinoma (pT2aN2M0, stage IIIA). Five days after lung surgery, the patient developed AE. Case 2 was a 67-year-old man who was referred to our hospital with suspected lung cancer, complaining of dry cough and DOE. The patient underwent left upper lobectomy with lymph node dissection for primary lung cancer, which was diagnosed as well-differentiated adenocarcinoma (pT2aN2M0, stage IIIA). Ten days after lung surgery, the patient developed AE. The levels of biomarkers, such as serum NE, redox balance [reduced GSH (rGSH)/oxidized GSH (GSSG)] in the blood, as well as the correlation between serial changes of these biomarkers and prognosis, were analyzed in 2 patients with postoperative IPF-AE associated with lung cancer. Interestingly, the serial changes of the serum rGSH/GSSG ratio may suggest the possibility of predicting the onset of postoperative AE and/or survival, along with serum NE levels. PMID- 27699035 TI - Membranous nephropathy associated with malignant pleural mesothelioma in an adult patient: A case report. AB - A 23-year-old man presented to our hospital with membranous nephropathy and received a detailed examination, including pleural biopsy, due to a feeling of chest oppression. The result of the pleural biopsy was malignant pleural mesothelioma. However, the patient did not have a history of asbestos or tobacco exposure. A review of the English literature identified only 7 reported cases of concomitant malignant mesothelioma and nephrotic syndrome. Furthermore, among the 7 cases reviewed, 6 had a history of asbestos exposure, 1 had a history of prolonged tobacco exposure and in only 1 case the renal pathology results revealed the presence of membranous nephropathy. PMID- 27699036 TI - Neoadjuvant chemotherapy followed by conization to spare fertility in cases of locally advanced cervical cancer: A case report and review of the literature. AB - The average age when cervical cancer is diagnosed is decreasing, resulting in a larger proportion of patients seeking fertility preservation. Therefore, a less radical approach that aims to preserve the potential for fertility during the treatment of cervical carcinoma is crucial. The present study reported a case of a patient with stage IB2 cervical cancer who exhibited pathological complete regression to neoadjuvant chemotherapy (NACT). This patient underwent deep cervical conization and laparoscopic lymphadenectomy to preserve her fertility. The patient gave birth at 29 weeks of gestation and exhibited no recurrent disease until May 2016 (72 months after surgery). This is the first, to the best of our knowledge, IB2 case treatment by NACT, followed by conization plus lymphadenectomy, producing favorable oncological and obstetrical outcome. The present study, together with data from a limited number of published articles, offers a new perspective in the preservation of fertility in young women with cervical cancer. Additional studies are required in a selected population. PMID- 27699037 TI - Trefoil factor 3 expression in epithelial ovarian cancer exerts a minor effect on clinicopathological parameters. AB - The role of trefoil factor 3 (intestinal) (TFF3) has been analyzed in numerous cancers, such as breast and gastrointestinal cancer, and has been associated with poor prognosis. However, the role of TFF3 in ovarian cancers is not clear. Expression analysis of TFF3 in 91 ovarian cancer patients was performed by immunohistochemistry of primary paraffin-embedded tumor samples. The results were scored according to staining intensity and percentage of positive tumor cells resulting in an immune-reactive score (IRS) of 0-12. These results were correlated with clinicopathological characteristics and survival. TFF3 expression in our patient cohort exhibited a tendency towards improved overall and progression-free survival (PFS). In TFF3-positive serous and high-grade serous ovarian cancers, the median PFS was 27.6 months [95% confidence interval (CI): 0 55.7] vs. 15.2 months in TFF3-negative tumors (95% CI: 13.8-16.6) (P=0.183). The median overall survival was 53.9 months in TFF3-positive tumors (95% CI: Non applicable) vs. 44.4 months in TFF3-negative cases (95% CI: 30.5-58.3) (P=0.36). TFF3 negativity was significantly associated with higher tumor grade (P=0.05). Based on our results, further studies are required in order to elucidate whether survival and chemosensitivity are affected by TFF3 expression in ovarian cancer. PMID- 27699039 TI - Extracranial oral cavity metastasis from glioblastoma multiforme: A case report. AB - Glioblastoma multiforme is the most common primary malignant brain tumor. The clinical outcome following diagnosis remains extremely poor. The treatment of choice is wide surgical resection of the visible tumor, frequently followed by adjuvant combined radiochemotherapy (RCTx) with temozolomide as the chemotherapeutic agent. Extracranial metastases are extremely rare, with <200 cases of extracranial metastases from glioblastoma multiforme reported in the literature to date. We herein present a case of a patient suffering from a fast growing metastasis to the oral cavity, completely filling the buccal cavity within 2 weeks, as the only manifestation of recurrent glioblastoma multiforme following initial surgical resection and adjuvant RCTx. PMID- 27699038 TI - Improvement of survival with postmastectomy radiotherapy in patients with 1-3 positive axillary lymph nodes: A systematic review and meta-analysis of the current literature. AB - In breast cancer with >4 positive axillary lymph nodes, it is common practice to deliver radiotherapy to the affected site following mastectomy. However, less is known regarding the benefits this may confer on women with 1-3 positive lymph nodes. In this meta-analysis, we aimed to assess whether post-mastectomy radiotherapy (PMRT) was beneficial for such patients. A literature review was conducted using the PubMed and Ovid databases. Selected studies were analysed and data regarding overall survival (OS) and locoregional recurrence (LRR) rates were extracted. Statistical analysis was then conducted in order to develop a combined risk ratio (RR) for both OS and LRR in the setting of PMRT in women with breast cancer with 1-3 positive lymph nodes. PMRT in women with 1-3 positive lymph nodes significantly reduced the risk of LRR, with a RR of 0.3 [95% confidence interval (CI): 0.23-0.38] and also showed a minor benefit in terms of OS (RR=1.03, 95% CI: 1.00-1.07). Therefore, in breast cancer patients with 1-3 positive lymph nodes, PMRT significantly reduced the risk of LRR and was associated with a minor OS benefit. Until the results of ongoing randomised controlled trials are published, PMRT should be recommended in this group of patients following a careful multidisciplinary discussion. PMID- 27699040 TI - Distinct patterns of angiogenic factor expression as a predictive factor of response to chemotherapy in stage IIIA non-small-cell lung cancer patients. AB - The expression of various angiogenic factors was assessed in tumour samples of patients with stage III non-small-cell lung cancer (NSCLC) and further evaluated in terms of response to induction paclitaxel-ifosfamide-cisplatin chemotherapy. Freshly isolated lung tumour specimens obtained by bronchoscopy from 70 stage IIIA NSCLC chemotherapy-naive patients were sampled and analysed for vascular endothelial growth factor receptor (VEGFR)-1, VEGFR-2 and VEGFR-3. Microvessel density was assessed through evaluating the angiogenic markers CD34 and CD105. Immunostaining scores were calculated by multiplying the percentage of labeled cells by the intensity of staining for each examined parameter. The overall mean immunostaining score value from all NSCLC samples was 7.83, 5.56 and 15.86 for VEGFR-1, VEGFR-2 and VEGFR-3, respectively. The overall mean value of the endothelial antigen CD34 was 16.29, whereas the expression of the CD105 antigen in endothelial cells yielded a multivariate distribution. Patients who responded to chemotherapy expressed significantly higher VEGFR-1 and VEGFR-3 mean values compared with non-responders (P<0.001). No significant difference was noted in VEGFR-2 mean values between these two groups (P=0.06). The CD34 mean value was significantly higher in responders (P<0.001), whereas there was no significant difference in CD105 expression between the two groups (P=0.07). Angiogenic marker expression proved to be a potential predictive factor of response to chemotherapy in stage III NSCLC. which merits further investigation. PMID- 27699042 TI - Simultaneous occurrence of non-Hodgkin lymphoma, renal cell carcinoma and oncocytoma: A case report. AB - We herein report the case of a 74 year-old woman with a diffuse large B-cell lymphoma and bilateral renal masses identified on computed tomography scans during the initial staging process. Following partial bilateral nephrectomy, histopathological examination revealed renal cell carcinoma (RCC) and oncocytoma in the left and the right kidneys, respectively. Shortly afterwards, lymphoma of the left palatine tonsil was diagnosed and the patient received chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP regimen), followed by radiotherapy. Due to metastasis of the RCC to the right breast, pancreas and the area of the left psoas major muscle, systemic treatment with pazopanib was commenced. To the best of our knowledge, this is the first reported case of simultaneous diagnosis of non-Hodgkin lymphoma (NHL), RCC and oncocytoma. The aim of this study was to review the related literature, discuss issues regarding the management of this unusual case and identify possible common etiopathological mechanisms underlying the simultaneous occurrence of NHL, RCC and oncocytoma. PMID- 27699041 TI - Significance of defect closure following transanal local full-thickness excision of rectal malignant tumors. AB - Transanal excision (TAE) for rectal tumors is increasingly applied and it is generally recommended that the defect following full-thickness excision should be closed. The aim of this study was to compare the complications and anal function following TAE between cases where the defect was closed and those where it was not. A total of 43 consecutive rectal malignant tumor patients eligible for TAE were investigated. Regarding anorectal function, incontinence was assessed using the Wexner score. The defect of the rectum was closed in 21 of the 43 patients. There were no significant differences between the two groups regarding gender, distance from the anal verge, tumor size, diagnosis and tumor site. There was a significantly higher number of postoperative complications of all grades and >=Clavien-Dindo grade IIIa in the closure group (P=0.02 and 0.04, respectively). Regarding the Wexner score, there was no significant difference between the two groups (P=0.24). Compared with the closure group, the non-closure group had significantly fewer postoperative complications of all grades and >=Clavien-Dindo grade IIIa. Moreover, there was no significant difference regarding the anorectal function between the two groups. Thus, suturing the rectal defect is not necessarily recommended following TAE. PMID- 27699043 TI - Comparative safety of BRAF and MEK inhibitors (vemurafenib, dabrafenib and trametinib) in first-line therapy for BRAF-mutated metastatic melanoma. AB - A retrospective observational study was conducted on patients diagnosed with serine/threonine-protein kinase B-Raf (BRAF)-mutated metastatic melanoma, who underwent first-line therapy with BRAF and mitogen-activated protein kinase kinase (MEK) inhibitors (vemurafenib, dabrafenib or a combination of dabrafenib and trametinib) at the Miguel Servet University Hospital (Zaragoza, Spain) between November, 2011 and August, 2015. The aim of this study was to analyse the toxicity produced by BRAF and MEK inhibitors. The most common toxicities were similar to those published in clinical trials, particularly arthralgia, alopecia and photosensitivity in the vemurafenib group; asthenia, hyperkeratosis and dry skin in the dabrafenib group; and diarrhoea and dry skin in the dabrafenib plus trametinib group. Toxicities that had not been described in clinical trials were also identified. Thus, the present study confirmed that the results obtained in clinical trials are similar to those obtained in clinical practice. PMID- 27699044 TI - Partial response to chemotherapy in a patient with retroperitoneal inflammatory myofibroblastic tumor. AB - Retroperitoneal inflammatory myofibroblastic tumor (IMT) is a rare lesion of unknown etiology. The management of IMT may be challenging due to its intermediate malignant potential, the possibility of local recurrence after surgical resection and its unique anatomic location, which makes radical resection impossible due to its proximity to vital structures. Thus, treatment for recurrence and metastasis mainly relies on chemotherapy. We herein report a case of a 60-year-old man with an IMT sized 6.7*5.1 cm, located in the left adrenal area, which was identified by a computed tomography (CT) scan of the abdomen. Radical surgical resection of the tumor was not feasible, as it was fixed to the left renal artery. After 5 months, the patient underwent CT-guided radiofrequency ablation of the re-growing tumor. An unresectable mass was detected in the patient's rectum by a CT scan of the pelvis. Subsequently, the patient underwent chemotherapy for the recurring and metastatic tumors. The chemotherapeutic regimens included epirubicin, dacarbazine and docetaxel. Over the last 6 months, after three cycles of therapy, the sizes of the primary and metastatic tumors had decreased on the follow-up CT scan. Thus, chemotherapy effectively controlled the disease in this case, following unsuccessful surgical resection and radiofrequency ablation. The present case report highlights the complexity of treatment in such cases and the significance of designing a clinical protocol for the treatment of IMT. PMID- 27699045 TI - Common carotid artery dissection caused by radiotherapy: A case report. AB - In the present study, a case of acute cerebral infarction with radiation-induced carotid artery dissection is reported. Carotid artery dissection is generally asymptomatic at the early stages. Due to the non-specific clinical manifestations of carotid artery dissection, a detailed inquiry of the past history of a patient has a critical role in making a diagnosis of radiation-induced common carotid artery dissection. Onset of acute ischemic stroke is the predominant manifestation, and for patients with a history of head-and-neck radiotherapy, dissection should be considered. The condition may progress rapidly, and result in a poor prognosis. Therefore, a correct early diagnosis and initiation of appropriate therapy may lead to rapid recovery, and influence the overall prognosis. PMID- 27699046 TI - Lower limb lymphedema in lung adenocarcinoma: Two case reports. AB - Breast and gynecological cancers and their treatment may cause lymphedema of the upper and lower extremities, respectively. We herein report the cases of two patients with lung adenocarcinoma who developed lymphedema of the lower extremities. One patient harbored an epidermal growth factor receptor mutation and the other patient harbored an anaplastic lymphoma kinase fusion gene. The patients had developed intra-abdominal lymph node metastases and received several lines of chemotherapy. In both patients, lymphedema in the lower extremities developed >30 months after the initiation of first-line chemotherapy. To the best of our knowledge, these are the first reported cases of lung cancer patients who developed lymphedema in the lower extremities. Although rarely, lymphedema of the lower extremities may develop long after successful therapy with molecular targeted therapy in advanced lung adenocarcinoma patients with a specific genetic etiological background. PMID- 27699047 TI - Hypersomnia as the first presentation in a patient with insulinoma: A case report and review of the literature. AB - Insulinoma is a rare neuroendocrine tumor. Hypersomnia as the first presentation in a patient with insulinoma is even more rare and may be easy to misdiagnose. We are herein reporting a case of insulinoma initially presenting with prolonged sleep time and extreme difficulty in waking. The abovementioned symptoms occurred every 2-3 months. Over the last 2 months, the attacks had become more frequent and severe. On computed tomography examination, a 12*9-mm cystic nodule was detected in the uncinate process of the pancreas, which was pathologically diagnosed as insulinoma. Since resection, the symptom of hypersomnia has not occurred again. The aim of the present report was to raise awareness among physicians to consider insulinoma in the differential diagnosis of hypersomnia in patients without other known diseases. PMID- 27699049 TI - "Lachnoclostridium touaregense," a new bacterial species isolated from the human gut microbiota. AB - We report the main characteristics of "Lachnoclostridium touaregense" strain Marseille-P2415T (= CSUR P2415 = DSM 102219), a new bacterial species isolated from the gut microbiota of a healthy young girl from Niger. PMID- 27699050 TI - "Lagierella massiliensis," a new bacterium detected in human feces. AB - We report here the main characteristics of "Lagierella massiliensis" strain SIT14 (CSUR P2012), which was isolated from a stool specimen from a healthy 28-month old Senegalese boy. PMID- 27699048 TI - Successful treatment of non-small-cell lung cancer with afatinib and a glucocorticoid following gefitinib- and erlotinib-induced interstitial lung disease: A case report. AB - Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI)-induced interstitial lung disease (ILD) may be a life-threatening condition that may develop during treatment of lung cancer patients harboring EGFR mutations. We herein present the case of a 41-year-old female patient diagnosed with lung adenocarcinoma with an EGFR mutation (exon 19 deletion). The patient was treated with gefitinib followed by erlotinib and developed ILD induced by both EGFR-TKIs; furthermore, the patient acquired resistance to EGFR-TKI treatment. A repeat biopsy revealed a T790M mutation, which is associated with resistance to first generation EGFR-TKIs, along with an exon 19 deletion identified by cytology of the pleural fluid. Treatment with afatinib and prednisolone resulted in tumor shrinkage, without worsening of the ILD. The present case demonstrated that combination treatment with afatinib and a glucocorticoid may be effective for the treatment of lung cancer patients who develop EGFR-TKI-induced ILD. PMID- 27699051 TI - "Anaerotruncus massiliensis," a new species identified from human stool from an obese patient after bariatric surgery. AB - We report the main characteristics of a new bacterial species strain AT3T (CSUR = P2007, DSM = 100567) that was isolated from the stool sample collected from a 47 year-old obese French man after he underwent bariatric surgery. PMID- 27699052 TI - Induction treatment of previously undiagnosed ANCA-associated vasculitis in a renal transplant patient with Rituximab. AB - We report the case of a 40-year-old female transplant patient with undiagnosed ANCA-associated vasculitis (AAV) and renal allograft dysfunction who achieved disease remission with restoration of transplant function following induction therapy with rituximab. There are currently no trial data looking at the use of rituximab for induction of remission of renal transplant patients with AAV. Although recurrence of AAV following renal transplantation is rare, such patients have invariably had multiple previous exposures to induction and maintenance immunosuppressive regimens, often limiting treatment options post transplantation. In this case, rituximab was well tolerated with no side effects, and was successful in salvaging transplant function. Optimal treatment regimens for relapsed AAV in the transplant population are not known, and clinical trials are needed to evaluate the efficacy and safety of rituximab at inducing and maintaining disease remission in relapsed AAV following transplantation. PMID- 27699054 TI - Opsoclonus-myoclonus-ataxia syndrome in an HIV-infected child. AB - Opsoclonus-myoclonus-ataxia (OMA) syndrome typically presents with chaotic eye movements and myoclonus with some patients exhibiting ataxia and behavioural disturbances. The pathogenesis may be inflammatory with an infectious or paraneoplastic trigger. We present a 13-year-old HIV-infected girl who was initially started on highly active antiretroviral therapy (HAART) in March 2013 with a CD4 count of 79 cells/cumm. Initially, the patient did not comply with treatment, resulting in a CD4+ count of 77 cells/mm3 in November 2015 and prompting a new HAART scheme comprising lamivudine, tenofovir and ritonavir boosted atazanavir. Shortly after starting this scheme, she developed OMA syndrome in January 2016. She was treated with intravenous immunoglobulin and methylprednisolone followed by oral steroids along with oral clonazepam and gradually recovered. We suggest immune reconstitution inflammatory syndrome as a possible aetiology of OMA in HIV-infected children. PMID- 27699053 TI - Lessons from treatment resistant hyperlipidaemia. AB - A 68-year-old woman was referred to Lipid Clinic with sudden deterioration of previously well-controlled primary hyperlipidaemia. Investigations revealed nephrotic range proteinuria, leading to urgent renal biopsy and a diagnosis of amyloidosis. Chemotherapy was successful in stabilising renal function, reducing proteinuria and eliminating serum paraprotein. The resistant hyperlipidaemia subsequently resolved. Whilst hyperlipidaemia is pathognomonic of nephrotic syndrome, it is rarely the first characteristic identified by clinicians, often preceded by the identification of oedema or proteinuria. This case is an unusual example of a nephrotic syndrome presenting to Lipid Clinic as a resistant primary hyperlipidaemia, and highlights the importance of considering superimposed secondary causes of hyperlipidaemia in treatment resistant cases. PMID- 27699055 TI - A rare presentation of spontaneous internal carotid artery dissection with Horner's syndrome, VIIth, Xth and XIIth nerve palsies. AB - Spontaneous internal carotid artery dissection (sICAD) is an uncommon cause of isolated cranial nerve palsies. Commonly patients present with stroke, headache, facial pain and Horner's syndrome, with upto 16% having cranial nerve palsies. We present the case of a 55-year-old man who presented with hoarseness, dysphagia and tongue swelling, mimicking a tongue base tumor. He was found to have unilateral VIIth, Xth and XIIth nerve palsies with Horner's syndrome. Magnetic resonance imaging showed high signal changes and loss of signal void in right internal carotid artery, later confirmed by Angiography as a dissection with pseudo-aneurysm. He was started on anticoagulation and made a good recovery on discharge. This case presents a unique combination of cranial nerve palsies due to internal carotid artery dissection (ICAD) and to our knowledge is the first reported case in the literature. Early recognition and institution of appropriate therapy is critical to prevention of ischemic stroke. PMID- 27699056 TI - Management of anthracycline extravasation into the pleural space. AB - Anthracycline extravasation is a feared complication of intravenous (i.v.) chemotherapy due to the tissue toxicity of this group of drugs. We describe a 54 year-old woman with history of stage IIIa breast cancer, receiving adjuvant chemotherapy consisting of doxorubicin and cyclophosphamide. The chemotherapy was administered through a Poweport(r) device, the position of which was confirmed with fluoroscopy and function confirmed by flushing the line. Urgent intervention was required as patient was symptomatic and experienced severe right-sided pleuritic chest pain. Radiology also confirmed the extravasation of doxorubicin into the pleural space. Surgical washout of the pleural space and 3 days therapy with i.v. dexrazoxane were carried out to prevent tissue damage and long-term sequelae. Use of dexrazoxane should always be considered following intra-pleural extravasation because of its potential efficacy and reasonable tolerability. However, the best approach to extravasation injury is prevention by systematic implementation of careful, standardized, evidence-based administration techniques. PMID- 27699057 TI - Controlling the strontium-doping in calcium phosphate microcapsules through yeast regulated biomimetic mineralization. AB - Yeast cells have controllable biosorption on metallic ions during metabolism. However, few studies were dedicated to using yeast-regulated biomimetic mineralization process to control the strontium-doped positions in calcium phosphate microcapsules. In this study, the yeast cells were allowed to pre adsorb strontium ions metabolically and then served as sacrificing template for the precipitation and calcination of mineral shell. The pre-adsorption enabled the microorganism to enrich of strontium ions into the inner part of the microcapsules, which ensured a slow-release profile of the trace element from the microcapsule. The co-culture with human marrow stromal cells showed that gene expressions of alkaline phosphatase and Collagen-I were promoted. The promotion of osteogenic differentiation was further confirmed in the 3D culture of cell material complexes. The strategy using living microorganism as 'smart doping apparatus' to control incorporation of trace element into calcium phosphate paved a pathway to new functional materials for hard tissue regeneration. PMID- 27699058 TI - Stability research on polydopamine and immobilized albumin on 316L stainless steel. AB - In this study, the polydopamine (PDA) film was coated on polished 316Lss and then thermally treated at 150 degrees C (labeled as PDA-Th150), and the stability of coatings was also investigated. Straining test indicated that PDA-Th150 coating performed better in affording sufficient adherence to 316 L SS substrate. Moreover, both PDA and PDA-Th150 coating suffered slight swelling during immersion in deionized water (pH = 6.5). X-ray photoelectron spectroscopy results showed that during immersion, latent nucleophilic reaction via amines inside PDA coating occurred. This led to an enhanced cross-linking and thus gradually promoted the coating stability. Moreover, larger amount of bovine serum albumin (BSA) was immobilized onto PDA-Th150 coating and performed well in anti-platelet adhesion. A high retention of immobilized BSA was observed even after immersion for 30 days. These tests suggested that PDA was stable enough and performed well in surface functionalization, which might enrich the research and application of PDA. PMID- 27699059 TI - Ectopic osteogenesis and angiogenesis regulated by porous architecture of hydroxyapatite scaffolds with similar interconnecting structure in vivo. AB - The macro-pore sizes of porous scaffold play a key role for regulating ectopic osteogenesis and angiogenesis but many researches ignored the influence of interconnection between macro-pores with different sizes. In order to accurately reveal the relationship between ectopic osteogenesis and macro-pore sizes in dorsal muscle and abdominal cavities of dogs, hydroxyapatite (HA) scaffolds with three different macro-pore sizes of 500-650, 750-900 and 1100-1250 um were prepared via sugar spheres-leaching process, which also had similar interconnecting structure determined by keeping the d/s ratio of interconnecting window diameter to macro-pore size constant. The permeability test showed that the seepage flow of fluid through the porous scaffolds increased with the increase of macro-pore sizes. The cell growth in three scaffolds was not affected by the macro-pore sizes. The in vivo ectopic implantation results indicated that the macro-pore sizes of HA scaffolds with the similar interconnecting structure have impact not only the speed of osteogenesis and angiogenesis but also the space distribution of newly formed bone. The scaffold with macro-pore sizes of 750-900 um exhibited much faster angiogenesis and osteogenesis, and much more uniformly distribution of new bone than those with other macro-pore sizes. This work illustrates the importance of a suitable macro-pore sizes in HA scaffolds with the similar interconnecting structure which provides the environment for ectopic osteogenesis and angiogenesis. PMID- 27699060 TI - Efficient GSH delivery using PAMAM-GSH into MPP-induced PC12 cellular model for Parkinson's disease. AB - Glutathione (GSH) depletion has been an important contributor to the dysfunction of dopamine neurons. Polyamidoamine-GSH (PAMAM-GSH) was synthesized and the delivery effect of GSH into PC12 cells was tested. MTT assessment for cytotoxicity and reactive oxygen species (ROS) as well as nitrite oxide (NO) and intracelluar superoxide dismutase (SOD) detection for antioxidative ability were performed. Furthermore, the antiapoptotic ability was analysed by assessing caspase-3, JNK1/2 and Erk1/2 expression. Our data indicated that PAMAM-GSH is an effective agent to replenish GSH into PC12 cells. PAMAM-GSH developed its antioxidative and protective ability for 1-methyl-4-phenylpyridinium (MPP) induced PC12 cells by reducing the intracellular levels of ROS and SOD activity as well as decreasing the release of NO. Meanwhile, PAMAM-GSH could inhibit caspase-3 activation and might show its antiapoptotic ability to MPP-induced PC12 cells through JNK2/Erk1/2 pathway. In summary, these studies suggest that PAMAM GSH conjugate has an intrinsic ability to penetrate PC12 cells and deliver GSH into these cells which may provide a new strategy for clinical applications in the treatment of Parkinson's disease. PMID- 27699061 TI - Drug-nanoencapsulated PLGA microspheres prepared by emulsion electrospray with controlled release behavior. AB - The development of modern therapeutics has raised the requirement for controlled drug delivery system which is able to efficiently encapsulate bioactive agents and achieve their release at a desired rate satisfying the need of the practical system. In this study, two kind of aqueous model drugs with different molecule weight, Congo red and albumin from bovine serum (BSA) were nano-encapsulated in poly (dl-lactic-co-glycolic acid) (PLGA) microspheres by emulsion electrospray. In the preparation process, the aqueous phase of drugs was added into the PLGA chloroform solution to form the emulsion solution. The emulsion was then electrosprayed to fabricate drug-nanoencapsulated PLGA microspheres. The morphology of the PLGA microspheres was affected by the volume ratio of aqueous drug phase and organic PLGA phase (Vw/Vo ) and the molecule weight of model drugs. Confocal laser scanning microcopy showed the nanodroplets of drug phase were scattered in the PLGA microspheres homogenously with different distribution patterns related to Vw/Vo . With the increase of the volume ratio of aqueous drug phase, the number of nanodroplets increased forming continuous phase gradually that could accelerate drug release rate. Moreover, BSA showed a slower release rate from PLGA microspheres comparing to Congo red, which indicated the drug release rate could be affected by not only Vw/Vo but also the molecule weight of model drug. In brief, the PLGA microspheres prepared using emulsion electrospray provided an efficient and simple system to achieve controlled drug release at a desired rate satisfying the need of the practices.

AB - This study compares the safety and efficiency of two techniques in microendoscopic discectomy (MED) for lumbar disc herniation. The two techniques are MED with automatic nerve retractor and MED with nerve hook which had been widely used for many years. The former involves a newly developed MED device which contains three parts to protect nerve roots during operation. Four hundred and twenty-eight patients underwent MED treatments between October 2010 and September 2015 were recruited and randomized to either intraoperative utilization of automatic nerve retractor (n = 315, group A) or application of nerve hook during surgery (n = 113, group B). Operation time and intraoperative bleeding volume were evaluated. Simultaneously, Visual Analogue Scales (VAS) and muscle strength grading were performed preoperatively, and 1, 2, 3 days, 1, 2 weeks, 3 and 6 months postoperatively. No dramatic difference of pain intensity was observed between the two groups before surgery and 6 months after surgery (P > 0.05). The operation time was shorter in group A (30.30 +/- 1.89 min) than that in group B (59.41 +/- 3.25 min). Group A (67.83 +/- 13.14 ml) experienced a significant decrease in the amount of blood loss volume when compared with group B (100.04 +/- 15.10 ml). There were remarkable differences of VAS score and muscle strength grading after postoperative 1, 2, 3 days, 1, 2 weeks and 3 months between both groups (P <= 0.05). MED with automatic nerve retractor effectively shortened operation time, decreased the amount of bleeding, down-regulated the incidence of nerve traction injury.

AB - In order to establish and standardize the rabbit rib segmental bone defect model, it is of vital importance to determine rabbit rib critical size defect (CSD). According to the general time needed for spontaneous long-bone regeneration, three-month observation period was set to determine the CSD. The rabbit rib segmental bone defects with different sizes from 1 to 5 cm with or without periosteum were performed in the eighth rib of 4-month-old male New Zealand rabbits and underwent X-ray examinations at the 4th, 8th and 12th weeks postoperatively. The gross and histological examinations at postoperative week 12 were evaluated, which showed that the critical sizes in the rabbit rib models with and without periosteum were 5 and 2 cm, respectively. This study provides prerequisite data for establishing rabbit rib CSD model and evaluating bone materials using this model.

AB - This paper presents a hardware module design for the forward Binary Discrete Cosine Transform (BinDCT) and its implementation on a field programmable gate array device. Different architectures of the BinDCT module were explored to ensure the maximum efficiency. The elaboration of these architectures included architectural design, timing and pipeline analysis, hardware description language modeling, design synthesis, and implementation. The developed BinDCT hardware module presents a high efficiency in terms of operating frequency and hardware resources, which has made it suitable for the most recent video standards with high image resolution and refresh frequency. Additionally, the high hardware efficiency of the BinDCT would make it a very good candidate for time and resource-constrained applications. By comparison with several recent implementations of discrete cosine transform approximations, it has been shown that the proposed hardware BinDCT module presents the best performances. PMID- 27699067 TI - General expressions for downlink signal to interference and noise ratio in homogeneous and heterogeneous LTE-Advanced networks. AB - The interference is the most important problem in LTE or LTE-Advanced networks. In this paper, the interference was investigated in terms of the downlink signal to interference and noise ratio (SINR). In order to compare the different frequency reuse methods that were developed to enhance the SINR, it would be helpful to have a generalized expression to study the performance of the different methods. Therefore, this paper introduces general expressions for the SINR in homogeneous and in heterogeneous networks. In homogeneous networks, the expression was applied for the most common types of frequency reuse techniques: soft frequency reuse (SFR) and fractional frequency reuse (FFR). The expression was examined by comparing it with previously developed ones in the literature and the comparison showed that the expression is valid for any type of frequency reuse scheme and any network topology. Furthermore, the expression was extended to include the heterogeneous network; the expression includes the problem of co tier and cross-tier interference in heterogeneous networks (HetNet) and it was examined by the same method of the homogeneous one. PMID- 27699065 TI - Appetite Suppression and Antiobesity Effect of a Botanical Composition Composed of Morus alba, Yerba mate, and Magnolia officinalis. AB - Background. Obesity and its comorbidities continue to challenge the world at an alarming rate. Although the long term solution lies on lifestyle changes in the form of dieting and exercising, drug, medical food, or dietary supplement interventions are required for those who are already obese. Here we describe a standardized blend composed of extracts from three medicinal plants: Morus alba, Yerba mate, and Magnolia officinalis for appetite suppression and metabolic disorders management. Method. Extracts were standardized to yield a composition designated as UP601. Appetite suppression activity was tested in acute feed intake rat model. Efficacy was evaluated in C57BL/6J mouse models treated with oral doses of 1.3 g/kg/day for 7 weeks. Orlistat at 40 mg/kg/day was used as a positive control. Body compositions of mice were assessed using a dual energy X ray absorptiometry (DEXA). ELISA was done for insulin, leptin, and ghrelin level quantitation. Nonalcoholic steatohepatitis (NASH) scoring was conducted. Results. Marked acute hypophagia with 81.8, 75.3, 43.9, and 30.9% reductions in food intake at 2, 4, 6, and 24 hours were observed for UP601. Decreases in body weight gain (21.5% compared to the HFD at weeks 7 and 8.2% compared to baseline) and calorie intake (40.5% for the first week) were observed. 75.9% and 46.8% reductions in insulin and leptin, respectively, 4.2-fold increase in ghrelin level, and reductions of 18.6% in cholesterol and 59% in low-density lipoprotein were documented. A percentage body fat of 18.9%, 47.8%, 46.1%, and 30.4% was found for mice treated with normal control, HFD, Orlistat, and UP601, respectively. 59.3% less mesenteric fat pad and improved NASH scores were observed for UP601. Conclusion. UP601, a standardized botanical composition from Morus alba, Yerba mate, and Magnolia officinalis could be used as a natural alternative for appetite suppression, maintaining healthy body weight and metabolism management. PMID- 27699068 TI - Validation Protocol of Vitamin D Supplementation in Patients with HIV-Infection. AB - Hypovitaminosis D and secondary hyperparathyroidism are frequent among HIV infected patients. As there are no data about the best supplementation therapy both in treatment and in maintenance, we conducted an observational study of 300 HIV-infected patients for whom vitamin D and parathormone (PTH) had been measured in order to validate a protocol of vitamin D supplementation in patients with HIV infection. Patients with vitamin D deficiency (defined as 25(OH)D < 10 ng/mL), insufficiency (defined as 25(OH)D < 20 ng/mL), or hyperparathyroidism (PTH > 65 pg/mL) were supplemented with cholecalciferol 16.000IU (0.266 mg) weekly (if deficiency) or fortnightly (if insufficiency or high PTH levels). Rates of normalization of 25(OH)D (levels above 20 ng/mL) and PTH levels (<65 pg/mL) were analyzed. Multivariate analysis of factors related to normalization was carried out. With a median follow-up of 2 years, 82.1% of patients with deficiency and 83.9% of cases with insufficiency reached levels above 20 ng/mL. However, only 67.2% of individuals with hyperparathyroidism at baseline reached target levels (<65 pg/mL). Independent factors for not achieving PTH objective were tenofovir (TDF) and protease inhibitors use. In HIV-infected patients with hypovitaminosis, the protocol of cholecalciferol supplementation normalized vitamin D levels regardless of antiretroviral regimen in a high proportion of patients but it was less effective to correct hyperparathyroidism. PMID- 27699069 TI - Personality Traits in College Students and Caregiving for a Relative with a Chronic Health Condition. AB - The purpose of this study was to investigate among college students the relationship between personality traits and willingness to care for a relative with a chronic health condition. 329 undergraduate students completed an online questionnaire. Hierarchical multiple regressions found that after controlling for demographics personality traits explained 10% of the variance in willingness to provide emotional care, 7% in instrumental care, and 7% in nursing care. Within these models, greater empathy was uniquely associated with willingness to provide emotional, instrumental, and nursing care for a family member in the future. Similarly, participants with high agreeableness were more willing to provide emotional care, and participant older age was a unique predictor of instrumental care. The results can help shape research on interventions that incorporate perspective taking, motivational interviewing, and training in life skills as a means of boosting college students' willingness to provide care for a relative with a chronic health condition. PMID- 27699070 TI - Effect of Purified Mushroom Tyrosinase on Melanin Content and Melanogenic Protein Expression. AB - In mammalian melanocytes, melanosome is a highly specialized organelle where melanin is synthesized. Melanin synthesis is controlled by tyrosinase, the vital enzyme in melanogenic pathway. The present investigation is based on an effect of purified mushroom tyrosinase of Agaricus bisporus on B16F10 melanocytes for the melanin production via blocking pigment cell machinery. Using B16F10 melanocytes showed that the stimulation of melanogenesis by purified tyrosinase is due to increased tyrosinase absorption. Cellular tyrosinase activity and melanin content in B16F10 melanocytes were increased by purified tyrosinase in a dose-dependent manner. Western blot analysis revealed that cellular tyrosinase levels were enhanced after treatment with purified tyrosinase for 48 hours. Furthermore, tyrosinase induced phosphorylation of cyclic adenosine monophosphate (cAMP) response element-binding protein (CREB) in a dose-dependent manner. The purified tyrosinase-mediated increase of tyrosinase activity was significantly attenuated by H89, LY294002, Ro-32-0432, and PD98059, cAMP-dependent protein kinase inhibitors. The results indicate that purified tyrosinase can be used as contestant for the treatment of vitiligous skin conditions. PMID- 27699071 TI - A Rare Case of Persistent Lactic Acidosis in the ICU: Glycogenic Hepatopathy and Mauriac Syndrome. AB - Mauriac syndrome is a rare disorder that can present with the single feature of glycogenic hepatopathy in children and adults with poorly controlled diabetes mellitus. An often underrecognized finding of glycogenic hepatopathy is lactic acidosis and hyperlactatemia. Primary treatment of glycogenic hepatopathy is improved long-term blood glucose control. Resolution of symptoms and hepatomegaly will occur with improvement in hemoglobin A1C. We present here a case of a young adult female presenting to the intensive care unit with Mauriac syndrome. This case demonstrates exacerbation of lactic acidosis in a patient with glycogenic hepatopathy treated for diabetic ketoacidosis with high dose insulin and dextrose. PMID- 27699072 TI - Two-Step Extraction of the Lower First Molar for Class III Treatment in Adult Patient. AB - The aim of this article is to describe a case report of Class III malocclusion treatment with lower first molar extraction. The 27-year-old Caucasian male patient presented a symmetric face with a straight profile, hyperdivergent growth pattern, molar and cuspid Class III relation, and an anterior crossbite as well as a mild crowding on cuspids area, in both upper and lower arches and a tendency to posterior crossbite. The treatment was performed by the use of Haas expansion appliance followed by an initial alignment and leveling of the upper and lower arches with a fixed edgewise appliance, extraction of lower teeth aiming the correction of the incisors proclination and end the treatment with a Class I molar relationship. It resulted in a significant change in the patient's profile, dentoalveolar Class III correction, upper arch expansion, leveling and alignment of the upper and lower arches, and improvement of tipping of the upper and lowers incisors. In cases of a dentoalveolar compensation in well positioned bone bases the treatment with fixed appliances is an alternative and extraction of lower teeth is considered. PMID- 27699073 TI - Early Diagnosis and Hematopoietic Stem Cell Transplantation for IL10R Deficiency Leading to Very Early-Onset Inflammatory Bowel Disease Are Essential in Familial Cases. AB - Alterations of immune homeostasis in the gut may result in development of inflammatory bowel disease. A five-month-old girl was referred for recurrent respiratory and genitourinary tract infections, sepsis in neonatal period, chronic diarrhea, perianal abscess, rectovaginal fistula, and hyperemic skin lesions. She was born to second-degree consanguineous, healthy parents. Her elder siblings were lost at 4 months of age due to sepsis and 1 year of age due to inflammatory bowel disease, respectively. Absolute neutrophil and lymphocyte counts, immunoglobulin levels, and lymphocyte subsets were normal ruling out severe congenital neutropenia and classic severe combined immunodeficiencies. Quantitative determination of oxidative burst was normal, excluding chronic granulomatous disease. Colonoscopy revealed granulation, ulceration, and pseudopolyps, compatible with colitis. Very early-onset colitis and perianal disease leading to fistula formation suggested probability of inherited deficiencies of IL-10 or IL-10 receptor. A mutation at position c.G477A in exon of the IL10RB gene, resulting in a stop codon at position p.W159X, was identified. The patient underwent myeloablative hematopoietic stem cell transplantation from full matched father at 11 months of age. Perianal lesions, chronic diarrhea, and recurrent infections resolved after transplantation. IL 10/IL-10R deficiencies must be considered in patients with early-onset enterocolitis. PMID- 27699074 TI - Successful Treatment of Uterine Arteriovenous Malformation due to Uterine Trauma. AB - Uterine arteriovenous malformation (AVM) is defined as abnormal and nonfunctional connections between the uterine arteries and veins. Although the patients typically present with vaginal bleeding, some patients may experience life threatening massive bleeding in some circumstances. The treatment of choice depends on the symptoms, age, desire for future fertility, and localization and size of the lesion; however, embolization of the uterine artery is the first choice in symptomatic AVM in patients at reproductive age with expectations of future fertility. We report a case of acquired AVM (after D/C) with an extensive lesion, which was successfully treated with bilateral uterine artery embolization (UAE).

AB - We present an extremely rare case of a pleomorphic rhabdomyosarcoma of the true vocal fold. The histopathological diagnosis was confirmed by immunohistochemistry. The patient was treated with radical surgery including total laryngectomy and radical neck dissection followed by postoperative radiotherapy. The clinicopathologic features of this rare malignancy are discussed together with a review of the literature. This case report and literature review highlights the more favorable prognosis of pleomorphic rhabdomyosarcoma in the larynx than in other locations.

AB - A patient with severe lupus nephritis developed thrombocytopenia during treatment with high-dose steroids. In addition to viral- or disease-induced cytopenia, the pathology was believed to arise from diverse contributing factors, such as thrombotic microangiopathy and heparin-related thrombocytopenia (HIT). By combining plasma exchange therapy and intravenous cyclophosphamide, we successfully controlled the SLE activity and improved the thrombocytopenia. An antecedent bacterial infection or SLE activity is believed to have contributed to the concurrent HIT. PMID- 27699077 TI - A Case of Successful Coil Embolization for a Late-Onset Type Ia Endoleak after Endovascular Aneurysm Repair with the Chimney Technique. AB - Juxtarenal aortic aneurysms (JRAAs) are challenging to treat by endovascular aneurysm repair (EVAR) procedures. The chimney technique with EVAR (Ch-EVAR) is one of the feasible and less invasive treatments for JRAAs. However, the main concern of Ch-EVAR is the potential risk of "gutters," which can lead to type Ia endoleak (EL). Most type Ia ELs after Ch-EVAR procedures occurred intraoperatively, and these ELs could be treated using an endovascular technique. However, late-onset type Ia ELs could be extremely rare, which might have a fear of conservative treatment. Type Ia ELs are associated with an increased risk of aneurysm rupture; therefore reintervention is recommended as soon as possible, and we should be aware of the occurrence of type Ia ELs after the Ch-EVAR procedure. PMID- 27699078 TI - Exposure to Persistent Organic Pollutants Predicts Telomere Length in Older Age: Results from the Helsinki Birth Cohort Study. AB - As the population ages, the occurrence of chronic pathologies becomes more common. Leukocyte telomere shortening associates to ageing and age-related diseases. Recent studies suggest that environmental chemicals can affect telomere length. Persistent organic pollutants (POPs) are most relevant, since they are ingested with foods, and accumulate in the body for a long time. This longitudinal study was undertaken to test if circulating POPs predict telomere length and shortening in elderly people. We studied 1082 subjects belonging to the Helsinki Birth Cohort Study (born 1934-1944), undergoing two visits (2001 2004 and 2011-2014). POPs (oxychlordane, trans-nonachlor, p, p'-DDE, PCB 153, BDE 47, BDE 153) were analysed at baseline. Relative telomere length was measured twice, '10 years apart, by quantitative real-time PCR. Oxychlordane, trans nonachlor and PCB-153 levels were significant predictors of telomere length and shortening. In men, we did not find a linear relationship between POPs exposure and telomere shortening. In women, a significant reduction across quartiles categories of oxychlordane and trans-nonachlor exposure was observed. Baseline characteristics of subjects in the highest POPs categories included higher levels of C-reactive protein and fasting glucose, and lower body fat percentage. This is one of few studies combining POPs and telomere length. Our results indicate that exposure to oxychlordane, trans-nonachlor and PCB 153 predicts telomere attrition. This finding is important because concentrations of POPs observed here occur in contemporary younger people, and may contribute to an accelerated ageing. PMID- 27699079 TI - Education and Genetic Risk Modulate Hippocampal Structure in Alzheimer's Disease. AB - Genetic and environmental protective factors and risks modulate brain structure and function in neurodegenerative diseases and their preclinical stages. We wanted to investigate whether the years of formal education, a proxy measure for cognitive reserve, would influence hippocampal structure in Alzheimer's disease patients, and whether apolipoprotein Eepsilon4 (APOE4) carrier status and a first degree family history of the disease would change a possible association. Fifty eight Alzheimer's disease patients underwent 3T magnetic resonance imaging. We applied a cortical unfolding approach to investigate individual subregions of the medial temporal lobe. Among patients homozygous for the APOE4 genotype or carrying both APOE4 and family history risks, lower education was associated with a thinner cortex in multiple medial temporal regions, including the hippocampus. Our data suggest that the years of formal education and genetic risks interact in their influence on hippocampal structure in Alzheimer's disease patients. PMID- 27699080 TI - Brain Formaldehyde is Related to Water Intake behavior. AB - A promising strategy for the prevention of Alzheimer's disease (AD) is the identification of age-related changes that place the brain at risk for the disease. Additionally, AD is associated with chronic dehydration, and one of the significant changes that are known to result in metabolic dysfunction is an increase in the endogenous formaldehyde (FA) level. Here, we demonstrate that the levels of uric formaldehyde in AD patients were markedly increased compared with normal controls. The brain formaldehyde levels of wild-type C57 BL/6 mice increased with age, and these increases were followed by decreases in their drinking frequency and water intake. The serum arginine vasopressin (AVP) concentrations were also maintained at a high level in the 10-month-old mice. An intravenous injection of AVP into the tail induced decreases in the drinking frequency and water intake in the mice, and these decreases were associated with increases in brain formaldehyde levels. An ELISA assay revealed that the AVP injection increased both the protein level and the enzymatic activity of semicarbazide-sensitive amine oxidase (SSAO), which is an enzyme that produces formaldehyde. In contrast, the intraperitoneal injection of formaldehyde increased the serum AVP level by increasing the angiotensin II (ANG II) level, and this change was associated with a marked decrease in water intake behavior. These data suggest that the interaction between formaldehyde and AVP affects the water intake behaviors of mice. Furthermore, the highest concentration of formaldehyde in vivo was observed in the morning. Regular water intake is conducive to eliminating endogenous formaldehyde from the human body, particularly when water is consumed in the morning. Establishing good water intake habits not only effectively eliminates excess formaldehyde and other metabolic products but is also expected to yield valuable approaches to reducing the risk of AD prior to the onset of the disease. PMID- 27699081 TI - Fear of Falling Correlates with Subtle Neuromuscular Balance and Strength Deficits of Fragility Fracture Patients. AB - Fragility fractures, or fractures occurring from a low-trauma event, are extremely prevalent among the elderly population worldwide and associated with significant mortality and morbidity. This study evaluated the relationship between FES-I Fear of Falling Survey results, self-reported activity restrictions via the SF-36 survey, and scores recorded by portable, inexpensive clinical assessment tools (CATs) during dynamic functional tasks. Low scores during these tasks may indicate functional deficits that put patients at risk for falls and subsequent fragility fractures. Forty-one subjects (20 fragility fracture patients, 21 controls without history of fragility fractures) over the age of 50 were recruited from three outpatient orthopaedic clinics. All subjects were administered a FES-I Fear of Falling Survey, a portion of an SF-36 survey, and tested using three different portable CATs: the Wii Balance Board, iPod Level Belt and Saehan Squeeze Hand Grip Dynamometer. There were several measured variables that showed a moderate correlation with Fear of Falling scores. Of note, correlations between FES-I scores and maximum hand grip strength for both the dominant hand (R= -0.302, p=0.069) and non-dominant hand (R= -0.309, p=0.059), as well as maximum anterior-posterior sway measured by the iPod Level Belt (R=0.320, p=0.056) were found to be marginally significant. In addition, the correlation between FES-I and average anterior-posterior sway was found to be significant (R=0.416, p=0.012). The Nintendo Wii and iPod Level Belt are relatively inexpensive, portable tools that can assess patients for subtle deficits during dynamic functional tasks. The results indicate that these tools can provide a more objective measure of a patient's limitations during daily activities such as walking by assigning them a numerical value and correlating this value to physical deficits that impact balance and coordination. In the future, CATs may also have a role in predicting outcomes and in individualizing care, therapy, and at-home preventive measures. PMID- 27699082 TI - Relevance Study on Cerebral Infarction and Resistin Gene Polymorphism in Chinese Han Population. AB - Recent research on genome-wide associations has implicated that the serum resistin level and its gene polymorphism are associated with cerebral infarction (CI) morbidity and prognosis, and could thereby regulate CI. This study aimed to investigate the association between the resistin single nucleotide polymorphism (SNP) and the susceptibility to CI in the Chinese Han population. A total of 550 CI patients and 313 healthy controls were genotyped. Nine SNPs of the resistin gene previously shown were sequenced and assessed for an association with CI. The numbers of GG genotype carriers of rs3219175 and rs3486119 in the CI group were significantly higher than those in the control group among the middle-aged group (aged 45-65), at 76% vs 67.9% (P=0.025) and 75.5% vs 67.9% (P=0.031). rs3219175 and rs34861192 were associated with CI in the dominant and superdominant models according to the genetic model analysis (P<0.05). Meanwhile, there was strong linkage disequilibrium among the rs34124816, rs3219175, rs34861192, rs1862513, rs3745367, 180C/G and rs3745369 sites. In a haplotype analysis, the occurrence rate of the haplotype AGGCAGC was 1.97 times (P<0.05) higher in the patient group than in the control group. In addition, the numbers of GG genotype carriers of rs3219175 and rs3486119 in the middle-aged male CI patients and the middle-aged small artery occlusion (SAO) CI patients were higher than those in the control group (P<0.05). In the Chinese Han middle-aged population, the GG gene type carriers of the resistin gene sites rs3219175 and rs34861192 had a high risk for CI onset, especially in middle-aged male patients and SAO CI in all middle-aged patients. PMID- 27699083 TI - Oxidative Stress-induced Telomere Length Shortening of Circulating Leukocyte in Patients with Obstructive Sleep Apnea. AB - The main mechanism of pathogenesis which causes systemic complications in obstructive sleep apnea (OSA) patients is believed to be intermittent hypoxia induced intermediary effect and it depends on the burden of oxidative stress during sleep. We aimed to search the predictive markers which reflect the burden of systemic oxidative stress in patients with OSA and whether excessive telomere length shortening is a characteristic feature that can assess oxidative stress levels. We used quantitative PCR to measure telomere length using peripheral blood genomic DNA. Telomere lengths were compared in an age- and body mass index (BMI)-dependent manner in 34 healthy volunteers and 43 OSA subjects. We also performed reactive oxygen species assay to measure the concentration of hydrogen peroxide in the peripheral blood of healthy volunteers and OSA subjects. We found that the serum concentration of hydrogen peroxide was considerably higher in OSA patients, and that this was closely related with the severity of OSA. Significantly shortened telomere length was observed in the circulating leukocytes of the peripheral blood of OSA patients, and telomere length shortening was aggravated more acutely in an age- and BMI-dependent manner. An inverse correlation was observed between the concentration of hydrogen peroxide and the telomere length of OSA patients and excessive telomere length shortening was also linked to severity of OSA. The results provided evidence that telomere length shortening or excessive cellular aging might be distinctive in circulating leukocyte of OSA patients and may be an predictive biomarker for reflect the burden of oxidative stress in the peripheral blood of OSA patients. PMID- 27699084 TI - Serum IL-33 Is a Novel Diagnostic and Prognostic Biomarker in Acute Ischemic Stroke. AB - Interleukin-33 (IL-33), a newly recognized IL-1 family member, is expressed in various tissues and cells, and involved in pathogenesis of many human diseases. For example, IL-33 plays a protective role in cardiovascular diseases. However, the role of IL-33 in acute ischemic stroke (AIS) remains unclear. This study aims to investigate whether IL-33 level in AIS patient serum can be used as a potential diagnostic and prognostic marker. The study included two hundred and six patients with first-ever ischemic stroke, who were admitted within 72 hours after stroke onset. The serum level of IL-33 was measured with ELISA and the severity of AIS patients on admission was evaluated based on the National Institutes of Health Stroke Scale (NIHSS) score. The functional outcome at 3 months was determined using the Barthel index (BI). We found that serum IL-33 was significantly higher (P < 0.001) in patients with AIS [57.68 ng/L (IQR, 44.95 76.73)] compared with healthy controls [47.48 ng/L (IQR, 38.67-53.78)]. IL-33 was an independent diagnostic biomarker for AIS with an OR of 1.051 (95%Cl, 1.018 1.085; P=0.002). Serum IL-33 was higher (P < 0.05) in the stroke patients with small cerebral infarction volume compared to AIS patients with large cerebral infarction. In addition, serum IL-33 was also significantly higher (P = 0.001) in the patients with mild stroke, compared to the patients with severe stroke. Furthermore, serum IL-33 level in AIS patients with a worse outcome was higher (P < 0.001) compared to AIS patients with a better outcome. IL-33 was also an independent predictor for the functional outcome with an adjusted OR of 0.932 (95% CI, 0.882-0.986). Our results suggest that the lower level of serum IL-33 is associated with large infarction volume and greater stroke severity in AIS patients. Thus, IL-33 can be used as a novel and independent diagnostic and predicting prognostic marker in AIS.

AB - Among various therapeutic approaches for stroke, treatment with human umbilical cord mesenchymal stem cells (hUC-MSCs) has acquired some promising results. However, the underlying mechanisms remain unclear. We analyzed the protein expression spectrum of the cortical peri-infarction region after ischemic stroke followed by treatment with hUC-MSCs, and found 16 proteins expressed differentially between groups treated with or without hUC-MSCs. These proteins were further determined by Gene Ontology term analysis and network with CD200 CD200R1, CCL21-CXCR3 and transcription factors. Three of them: Abca13, Grb2 and Ptgds were verified by qPCR and ELISA. We found the protein level of Abca13 and the mRNA level of Grb2 consistent with results from the proteomic analysis. Finally, the function of these proteins was described and the potential proteins that deserve to be further studied was also highlighted. Our data may provide possible underlying mechanisms for the treatment of stroke using hUC-MSCs. PMID- 27699089 TI - In vivo fluorescence imaging of hepatocellular carcinoma xenograft using near infrared labeled epidermal growth factor receptor (EGFR) peptide. AB - Minimally-invasive surgery of hepatocellular carcinoma (HCC) can be limited by poor tumor visualization with white light. We demonstrate systemic administration of a Cy5.5-labeled peptide specific for epidermal growth factor receptor (EGFR) to target HCC in vivo in a mouse xenograft model. We attached a compact imaging module to the proximal end of a medical laparoscope to collect near-infrared fluorescence and reflectance images concurrently at 15 frames/sec. We measured a mean target-to-background ratio of 2.99 +/- 0.22 from 13 surgically exposed subcutaneous human HCC tumors in vivo in 5 mice. This integrated imaging methodology is promising to guide laparoscopic resection of HCC. PMID- 27699088 TI - Efficient Benzimidazolidinone Synthesis via Rhodium-Catalyzed Double Decarbonylative C-C Activation/Cycloaddition between Isatins and Isocyanates. AB - The first decarbonylative cycloaddition of less-strained cyclic ketones (isatins) with isocyanates is reported. Initiated by C-C activation, this distinct [5-2+2] transformation provides a rapid entry to access various benzimidazolidinone derivatives, through which a wide range of isocyanates can be efficiently coupled with broad functional group tolerance. A modified one-pot process, combining Curtius rearrangement and C-C activation, was also achieved by using acyl azides as the starting materials. Detailed mechanistic study revealed a surprising double-decarbonylative reaction pathway. The novel reactivity discovered in this basic research is expected to shed light on developing new heterocycle formation methods through a C-C/isocyanate coupling. PMID- 27699091 TI - Multimodal optical coherence tomography and fluorescence lifetime imaging with interleaved excitation sources for simultaneous endogenous and exogenous fluorescence. AB - Multimodal imaging probes a variety of tissue properties in a single image acquisition by merging complimentary imaging technologies. Exploiting synergies amongst the data, algorithms can be developed that lead to better tissue characterization than could be accomplished by the constituent imaging modalities taken alone. The combination of optical coherence tomography (OCT) with fluorescence lifetime imaging microscopy (FLIM) provides access to detailed tissue morphology and local biochemistry. The optical system described here merges 1310 nm swept-source OCT with time-domain FLIM having excitation at 355 and 532 nm. The pulses from 355 and 532 nm lasers have been interleaved to enable simultaneous acquisition of endogenous and exogenous fluorescence signals, respectively. The multimodal imaging system was validated using tissue phantoms. Nonspecific tagging with Alexa Flour 532 in a Watanbe rabbit aorta and active tagging of the LOX-1 receptor in human coronary artery, demonstrate the capacity of the system for simultaneous acquisition of OCT, endogenous FLIM, and exogenous FLIM in tissues.

AB - Guanosine is a purine nucleoside with important functions in cell metabolism and a protective role in response to degenerative diseases or injury. The past decade has seen major advances in identifying the modulatory role of extracellular action of guanosine in the central nervous system (CNS). Evidence from rodent and cell models show a number of neurotrophic and neuroprotective effects of guanosine preventing deleterious consequences of seizures, spinal cord injury, pain, mood disorders and aging-related diseases, such as ischemia, Parkinson's and Alzheimer's diseases. The present review describes the findings of in vivo and in vitro studies and offers an update of guanosine effects in the CNS. We address the protein targets for guanosine action and its interaction with glutamatergic and adenosinergic systems and with calcium-activated potassium channels. We also discuss the intracellular mechanisms modulated by guanosine preventing oxidative damage, mitochondrial dysfunction, inflammatory burden and modulation of glutamate transport. New and exciting avenues for future investigation into the protective effects of guanosine include characterization of a selective guanosine receptor. A better understanding of the neuromodulatory action of guanosine will allow the development of therapeutic approach to brain diseases.

AB - Preservation of prostatic nerves is critical to recovery of a man's sexual potency after radical prostatectomy. A real-time imaging method of prostatic nerves will be helpful for nerve-sparing radical prostatectomy (NSRP). Polarization-sensitive optical coherence tomography (PS-OCT), which provides both structural and birefringent information of tissue, was applied for detection of prostatic nerves in both rat and human prostate specimens, ex vivo. PS-OCT imaging of rat prostate specimens visualized highly scattering and birefringent fibrous structures superficially, and these birefringent structures were confirmed to be nerves by histology or multiphoton microscopy (MPM). PS-OCT could easily distinguish these birefringent structures from surrounding other tissue compartments such as prostatic glands and fats. PS-OCT imaging of human prostatectomy specimens visualized two different birefringent structures, appearing fibrous and sheet-like. The fibrous ones were confirmed to be nerves by histology, and the sheet-like ones were considered to be fascias surrounding the human prostate. PS-OCT imaging of human prostatectomy specimens along the perimeter showed spatial variation in the amount of birefringent fibrous structures which was consistent with anatomy. These results demonstrate the feasibility of PS-OCT for detection of prostatic nerves, and this study will provide a basis for intraoperative use of PS-OCT. PMID- 27699092 TI - Combination of confocal principle and aperture stop separation improves suppression of crystalline lens fluorescence in an eye model. AB - Fluorescence lifetime imaging ophthalmoscopy (FLIO) is a new technique to detect changes in the human retina. The autofluorescence decay over time, generated by endogenous fluorophores, is measured in vivo. The strong autofluorescence of the crystalline lens, however, superimposes the intensity decay of the retina fluorescence, as the confocal principle is not able to suppress it sufficiently. Thus, the crystalline lens autofluorescence causes artifacts in the retinal fluorescence lifetimes determined from the intensity decays. Here, we present a new technique to suppress the autofluorescence of the crystalline lens by introducing an annular stop into the detection light path, which we call Schweitzer's principle. The efficacy of annular stops with an outer diameter of 7 mm and inner diameters of 1 to 5 mm are analyzed in an experimental setup using a model eye based on fluorescent dyes. Compared to the confocal principle, Schweitzer's principle with an inner diameter of 3 mm is able to reduce the simulated crystalline lens fluorescence to 4%, while 42% of the simulated retina fluorescence is preserved. Thus, we recommend the implementation of Schweitzer's principle in scanning laser ophthalmoscopes used for fundus autofluorescence measurements, especially the FLIO device, for improved image quality. PMID- 27699093 TI - In vitro neuronal depolarization and increased synaptic activity induced by infrared neural stimulation. AB - Neuronal responses to infrared neural stimulation (INS) are explored at the single cell level using patch-clamp electrophysiology. We examined membrane and synaptic responses of solitary tract neurons recorded in acute slices prepared from the Sprague-Dawley rat. Neurons were stimulated using a compact 1890 nm waveguide laser with light delivered to a small target area, comparable to the size of a single cell, via a single-mode fiber. We show that infrared radiation increased spontaneous synaptic event frequency, and evoked steady-state currents and neuronal depolarization. The magnitude of the responses was proportional to laser output. PMID- 27699094 TI - Visible-light optical coherence tomography-based multimodal retinal imaging for improvement of fluorescent intensity quantification. AB - We developed a spectral-domain visible-light optical coherence tomography (VIS OCT) based multimodal imaging technique which can accomplish simultaneous OCT and fluorescence imaging with a single broadband light source. Phantom experiments showed that by using the simultaneously acquired OCT images as a reference, the effect of light attenuation on the intensity of the fluorescent images by materials in front of the fluorescent target can be compensated. This capability of the multimodal imaging technique is of high importance for achieving quantification of the true intensities of autofluorescence (AF) imaging of the retina. We applied the technique in retinal imaging including AF imaging of the retinal pigment epithelium and fluorescein angiography (FA). We successfully demonstrated the effect of compensation on AF and FA images with the simultaneously acquired VIS-OCT images. PMID- 27699095 TI - Photonic sensing of arterial distension. AB - Most cardiovascular diseases, such as arteriosclerosis and hypertension, are directly linked to pathological changes in hemodynamics, i.e. the complex coupling of blood pressure, blood flow and arterial distension. To improve the current understanding of cardiovascular diseases and pave the way for novel cardiovascular diagnostics, innovative tools are required that measure pressure, flow, and distension waveforms with yet unattained spatiotemporal resolution. In this context, miniaturized implantable solutions for continuously measuring these parameters over the long-term are of particular interest. We present here an implantable photonic sensor system capable of sensing arterial wall movements of a few hundred microns in vivo with sub-micron resolution, a precision in the micrometer range and a temporal resolution of 10 kHz. The photonic measurement principle is based on transmission photoplethysmography with stretchable optoelectronic sensors applied directly to large systemic arteries. The presented photonic sensor system expands the toolbox of cardiovascular measurement techniques and makes these key vital parameters continuously accessible over the long-term. In the near term, this new approach offers a tool for clinical research, and as a perspective, a continuous long-term monitoring system that enables novel diagnostic methods in arteriosclerosis and hypertension research that follow the trend in quantifying cardiovascular diseases by measuring arterial stiffness and more generally analyzing pulse contours. PMID- 27699086 TI - Atrial Fibrillation: The Science behind Its Defiance. AB - Atrial fibrillation (AF) is the most prevalent arrhythmia in the world, due both to its tenacious treatment resistance, and to the tremendous number of risk factors that set the stage for the atria to fibrillate. Cardiopulmonary, behavioral, and psychological risk factors generate electrical and structural alterations of the atria that promote reentry and wavebreak. These culminate in fibrillation once atrial ectopic beats set the arrhythmia process in motion. There is growing evidence that chronic stress can physically alter the emotion centers of the limbic system, changing their input to the hypothalamic-limbic autonomic network that regulates autonomic outflow. This leads to imbalance of the parasympathetic and sympathetic nervous systems, most often in favor of sympathetic overactivation. Autonomic imbalance acts as a driving force behind the atrial ectopy and reentry that promote AF. Careful study of AF pathophysiology can illuminate the means that enable AF to elude both pharmacological control and surgical cure, by revealing ways in which antiarrhythmic drugs and surgical and ablation procedures may paradoxically promote fibrillation. Understanding AF pathophysiology can also help clarify the mechanisms by which emerging modalities aiming to correct autonomic imbalance, such as renal sympathetic denervation, may offer potential to better control this arrhythmia. Finally, growing evidence supports lifestyle modification approaches as adjuncts to improve AF control. PMID- 27699096 TI - Dark field optical imaging reveals vascular changes in an inducible hamster cheek pouch model during carcinogenesis. AB - In this study, we propose a low-cost cross-polarized dark field microscopy system for in vivo vascular imaging to detect head and neck cancer. A simple-to-use Gabor-filter-based image processing technique was developed to objectively and automatically quantify several important vascular features, including tortuosity, length, diameter and area fraction, from vascular images. Simulations were performed to evaluate the accuracies of vessel segmentation and feature extraction for our algorithm. Sensitivity and specificity for vessel segmentation of the Gabor masks both remained above 80% at all contrast levels when compared to gold-standard masks. Errors for vascular feature extraction were under 5%. Moreover, vascular contrast and vessel diameter were identified to be the two primary factors which affected the segmentation accuracies. After our algorithm was validated, we monitored the blood vessels in an inducible hamster cheek pouch carcinogen model over 17 weeks and quantified vascular features during carcinogenesis. A significant increase in vascular tortuosity and a significant decrease in vessel length were observed during carcinogenesis. PMID- 27699098 TI - Microdose fluorescence imaging of ABY-029 on an operating microscope adapted by custom illumination and imaging modules. AB - Fluorescence guided surgery has the potential to positively impact surgical oncology; current operating microscopes and stand-alone imaging systems are too insensitive or too cumbersome to maximally take advantage of new tumor-specific agents developed through the microdose pathway. To this end, a custom-built illumination and imaging module enabling picomolar-sensitive near-infrared fluorescence imaging on a commercial operating microscope is described. The limits of detection and system specifications are characterized, and in vivo efficacy of the system in detecting ABY-029 is evaluated in a rat orthotopic glioma model following microdose injections, showing the suitability of the device for microdose phase 0 clinical trials. PMID- 27699097 TI - Non-invasive diffuse correlation tomography reveals spatial and temporal blood flow differences in murine bone grafting approaches. AB - Longitudinal blood flow during murine bone graft healing was monitored non invasively using diffuse correlation tomography. The system utilized spatially dense data from a scanning set-up, non-linear reconstruction, and micro-CT anatomical information. Weekly in vivo measurements were performed. Blood flow changes in autografts, which heal successfully, were localized to graft regions and consistent across mice. Poor healing allografts showed heterogeneous blood flow elevation and high inter-subject variabilities. Allografts with tissue engineered periosteum showed responses intermediate to both autografts and allografts, consistent with healing observed. These findings suggest that spatiotemporal blood flow changes can be utilized to differentiate the degree of bone graft healing. PMID- 27699099 TI - Optofluidic chips with nanochannels for dynamic molecular detection using enhanced fluorescence. AB - The fabrication of a novel optofluidic chip using nanochannels optimized for DNA stretched molecules and optical detection by enhanced fluorescence is reported. The chips are composed of a series of microchannels that allow the transport of molecules in the femto-liter per second inside a fluid or gas. The nanochannels are surrounded by a photonic crystal structure to enhance the emission of fluorescent light from the molecules, which can travel along the nanochannel, allowing for enhanced optical detection of the molecules in motion. The photonic crystal structure provides an enhancement up to 2.5 times in the light emitted from fluorescent molecules inside the nanochannels which increases to around 250 when normalized to the area of the nanochannels emitting fluorescence. The results may help to the detection of fluorescent molecules (like marked-DNA) in series by speeding it and allowing the use of less sophisticated equipment. PMID- 27699100 TI - Structure-adaptive CBCT reconstruction using weighted total variation and Hessian penalties. AB - The exposure of normal tissues to high radiation during cone-beam CT (CBCT) imaging increases the risk of cancer and genetic defects. Statistical iterative algorithms with the total variation (TV) penalty have been widely used for low dose CBCT reconstruction, with state-of-the-art performance in suppressing noise and preserving edges. However, TV is a first-order penalty and sometimes leads to the so-called staircase effect, particularly over regions with smooth intensity transition in the reconstruction images. A second-order penalty known as the Hessian penalty was recently used to replace TV to suppress the staircase effect in CBCT reconstruction at the cost of slightly blurring object edges. In this study, we proposed a new penalty, the TV-H, which combines TV and Hessian penalties for CBCT reconstruction in a structure-adaptive way. The TV-H penalty automatically differentiates the edges, gradual transition and uniform local regions within an image using the voxel gradient, and adaptively weights TV and Hessian according to the local image structures in the reconstruction process. Our proposed penalty retains the benefits of TV, including noise suppression and edge preservation. It also maintains the structures in regions with gradual intensity transition more successfully. A majorization-minimization (MM) approach was designed to optimize the objective energy function constructed with the TV-H penalty. The MM approach employed a quadratic upper bound of the original objective function, and the original optimization problem was changed to a series of quadratic optimization problems, which could be efficiently solved using the Gauss-Seidel update strategy. We tested the reconstruction algorithm on two simulated digital phantoms and two physical phantoms. Our experiments indicated that the TV-H penalty visually and quantitatively outperformed both TV and Hessian penalties. PMID- 27699101 TI - Multi-spectral photoacoustic elasticity tomography. AB - The goal of this work was to develop and validate a spectrally resolved photoacoustic imaging method, namely multi-spectral photoacoustic elasticity tomography (PAET) for quantifying the physiological parameters and elastic modulus of biological tissues. We theoretically and experimentally examined the PAET imaging method using simulations and in vitro experimental tests. Our simulation and in vitro experimental results indicated that the reconstructions were quantitatively accurate in terms of sizes, the physiological and elastic properties of the targets. PMID- 27699102 TI - Supercontinuum as a light source for miniaturized endoscopes. AB - In this work, we have successfully implemented supercontinuum based illumination through single fiber coupling. The integration of a single fiber illumination with a miniature CMOS sensor forms a very slim and powerful camera module for endoscopic imaging. A set of tests and in vivo animal experiments are conducted accordingly to characterize the corresponding illuminance, spectral profile, intensity distribution, and image quality. The key illumination parameters of the supercontinuum, including color rendering index (CRI: 72%~97%) and correlated color temperature (CCT: 3,100K~5,200K), are modified with external filters and compared with those from a LED light source (CRI~76% & CCT~6,500K). The very high spatial coherence of the supercontinuum allows high luminosity conduction through a single multimode fiber (core size~400MUm), whose distal end tip is attached with a diffussion tip to broaden the solid angle of illumination (from less than 10 degrees to more than 80 degrees ). PMID- 27699103 TI - Optical coherence tomography endoscopic probe based on a tilted MEMS mirror. AB - This paper reports a compact microendoscopic OCT probe with an outer diameter of only 2.7 mm. The small diameter is enabled by a novel 2-axis scanning MEMS mirror with a preset 45 degrees tilted angle. The tilted MEMS mirror is directly integrated on a silicon optical bench (SiOB). The SiOB provides mechanical support and electrical wiring to the mirror plate via a set of bimorph flexure, enabling a compact probe mount design without the requirement of a 45 degrees slope, which is capable to dramatically reduce the probe size and ease the assembly process. Additionally, the SiOB also provides trenches with properly designed opening widths for automatic alignment of the MEMS mirror, GRIN lens and optical fiber. The 45 degrees -tilted MEMS mirror plate is actuated by four electrothermal bimorph actuators. The packaged 2.7 mm-diameter probe offers 2 axis side-view optical scanning with a large optical scan range of 40 degrees at a low drive voltage of 5.5 Vdc in both axes, allowing a lateral scan area of 2.2 mm * 2.2 mm at a 3 mm working distance. High-resolution 2D and 3D OCT images of the IR card, ex vivo imaging of meniscus specimens and rat brain slices, in vivo imaging of the human finger and nail have been obtained with a TDOCT system. PMID- 27699104 TI - Tracking single fluorescent particles in three dimensions via extremum seeking. AB - The ability to track single fluorescent particles in three-dimensions with sub diffraction limit precision as well as sub-millisecond temporal resolution has enabled the understanding of many biophysical phenomena at the nanometer scale. While there are several techniques for achieving this, most require complicated experimental setups that are expensive to implement. These methods can offer superb performance but their complexity may be overwhelming to the end-user whose aim is only to understand the feature being imaged. In this work, we describe a method for tracking a single fluorescent particle using a standard confocal or multi-photon microscope configuration. It relies only on the assumption that the relative position of the measurement point and the particle can be actuated and that the point spread function has a global maximum that coincides with the particle's position. The method uses intensity feedback to calculate real-time position commands that "seek" the extremum of the point spread function as the particle moves through its environment. We demonstrate the method by tracking a diffusing quantum dot in a hydrogel on a standard epifluorescent confocal microscope. PMID- 27699105 TI - Imaging hemodynamic response after ischemic stroke in mouse cortex using visible light optical coherence tomography. AB - Visible-light optical coherence tomography (Vis-OCT) is an emerging technology that can image hemodynamic response in microvasculature. Vis-OCT can retrieve blood oxygen saturation (sO2) mapping using intrinsic optical absorption contrast while providing high-resolution anatomical vascular structures at the same time. To improve the accuracy of Vis-OCT oximetry on vessels embedded in highly scattering medium, i.e., brain cortex, we developed and formulated a novel dual depth sampling and normalization strategy that allowed us to minimize the detrimental effect of ubiquitous tissue scattering. We applied our newly developed approach to monitor the hemodynamic response in mouse cortex after focal photothrombosis. We observed vessel dilatation, which was negatively correlated with the original vessel diameter, in the penumbra region. The sO2 of vessels in the penumbra region also dropped below normal range after focal ischemia. PMID- 27699107 TI - Dual-modality endomicroscopy with co-registered fluorescence and phase contrast. AB - We describe a dual-modality laser scanning endomicroscope that provides simultaneous fluorescence contrast based on confocal laser endomicroscopy (CLE) and phase-gradient contrast based on scanning oblique back-scattering microscopy (sOBM). The probe consists of a 2.6mm-diameter micro-objective attached to a 30,000-core flexible fiber bundle. The dual contrasts are inherently co registered, providing complementary information on labeled and un-labeled sample structure. Proof of principle demonstrations are presented with ex-vivo mouse colon tissue. PMID- 27699106 TI - Combined multi-modal photoacoustic tomography, optical coherence tomography (OCT) and OCT angiography system with an articulated probe for in vivo human skin structure and vasculature imaging. AB - Cutaneous blood flow accounts for approximately 5% of cardiac output in human and plays a key role in a number of a physiological and pathological processes. We show for the first time a multi-modal photoacoustic tomography (PAT), optical coherence tomography (OCT) and OCT angiography system with an articulated probe to extract human cutaneous vasculature in vivo in various skin regions. OCT angiography supplements the microvasculature which PAT alone is unable to provide. Co-registered volumes for vessel network is further embedded in the morphologic image provided by OCT. This multi-modal system is therefore demonstrated as a valuable tool for comprehensive non-invasive human skin vasculature and morphology imaging in vivo. PMID- 27699108 TI - Algorithms for differentiating between images of heterogeneous tissue across fluorescence microscopes. AB - Fluorescence microscopy can be used to acquire real-time images of tissue morphology and with appropriate algorithms can rapidly quantify features associated with disease. The objective of this study was to assess the ability of various segmentation algorithms to isolate fluorescent positive features (FPFs) in heterogeneous images and identify an approach that can be used across multiple fluorescence microscopes with minimal tuning between systems. Specifically, we show a variety of image segmentation algorithms applied to images of stained tumor and muscle tissue acquired with 3 different fluorescence microscopes. Results indicate that a technique called maximally stable extremal regions followed by thresholding (MSER + Binary) yielded the greatest contrast in FPF density between tumor and muscle images across multiple microscopy systems. PMID- 27699109 TI - Design of a fiber-optic multiphoton microscopy handheld probe. AB - We have developed a fiber-optic multiphoton microscopy (MPM) system with handheld probe using femtosecond fiber laser. Here we present the detailed optical design and analysis of the handheld probe. The optical systems using Lightpath 352140 and 352150 as objective lens were analyzed. A custom objective module that includes Lightpath 355392 and two customized corrective lenses was designed. Their performances were compared by wavefront error, field curvature, astigmatism, F-theta error, and tolerance in Zemax simulation. Tolerance analysis predicted the focal spot size to be 1.13, 1.19 and 0.83 um, respectively. Lightpath 352140 and 352150 were implemented in experiment and the measured lateral resolution was 1.22 and 1.3 um, respectively, which matched with the prediction. MPM imaging by the handheld probe were conducted on leaf, fish scale and rat tail tendon. The MPM resolution can potentially be improved by the custom objective module. PMID- 27699110 TI - Single cell ionization by a laser trap: a preliminary study in measuring radiation dose and charge in BT20 breast carcinoma cells. AB - In this work, a preliminary study in the application of a laser trap for ionization of living carcinoma cells is presented. The study was conducted using BT20 breast carcinoma cells cultured and harvested in our laboratory. Each cell, for a total of 50 cells, was trapped and ionized by a high intensity infrared laser at 1064 nm. The threshold radiation dose and the resultant charge from the ionization for each cell were determined. With the laser trap serving as a radiation source, the cell underwent dielectric breakdown of the membrane. When this process occurs, the cell becomes highly charged and its dielectric susceptibility changes. The charge creates an increasing electrostatic force while the changing dielectric susceptibility diminishes the strength of the trapping force. Consequently, at some instant of time the cell gets ejected from the trap. The time inside the trap while the cell is being ionized, the intensity of the radiation, and the post ionization trajectory of the cell were used to determine the threshold radiation dose and the charge for each cell. The measurement of the charge vs ionization radiation dose at single cell level could be useful in the accuracy of radiotherapy as the individual charges can collectively create a strong enough electrical interaction to cause dielectric breakdown in other cells in a tumor. PMID- 27699111 TI - Multiphoton excited hemoglobin fluorescence and third harmonic generation for non invasive microscopy of stored blood. AB - Red blood cells (RBC) in two-photon excited fluorescence (TPEF) microscopy usually appear as dark disks because of their low fluorescent signal. Here we use 15fs 800nm pulses for TPEF, 45fs 1060nm pulses for three-photon excited fluorescence, and third harmonic generation (THG) imaging. We find sufficient fluorescent signal that we attribute to hemoglobin fluorescence after comparing time and wavelength resolved spectra of other expected RBC endogenous fluorophores: NADH, FAD, biliverdin, and bilirubin. We find that both TPEF and THG microscopy can be used to examine erythrocyte morphology non-invasively without breaching a blood storage bag. PMID- 27699112 TI - Continuous cerebral hemodynamic measurement during deep hypothermic circulatory arrest. AB - While survival of children with complex congenital heart defects has improved in recent years, roughly half suffer neurological deficits suspected to be related to cerebral ischemia. Here we report the first demonstration of optical diffuse correlation spectroscopy (DCS) for continuous and non-invasive monitoring of cerebral microvascular blood flow during complex human neonatal or cardiac surgery. Comparison between DCS and Doppler ultrasound flow measurements during deep hypothermia, circulatory arrest, and rewarming were in good agreement. Looking forward, DCS instrumentation, alone and with NIRS, could provide access to flow and metabolic biomarkers needed by clinicians to adjust neuroprotective therapy during surgery. PMID- 27699113 TI - Minimum change in spherical aberration that can be perceived. AB - It is important to know the visual sensitivity to optical blur from both a basic science perspective and a practical point of view. Of particular interest is the sensitivity to blur induced by spherical aberration because it is being used to increase depth of focus as a component of a presbyopic solution. Using a flicker detection-based procedure implemented on an adaptive optics visual simulator, we measured the spherical aberration thresholds that produce just-noticeable differences in perceived image quality. The thresholds were measured for positive and negative values of spherical aberration, for best focus and + 0.5 D and + 1.0 D of defocus. At best focus, the SA thresholds were 0.20 +/- 0.01 um and -0.17 +/ 0.03 um for positive and negative spherical aberration respectively (referred to a 6-mm pupil). These experimental values may be useful in setting spherical aberration permissible levels in different ophthalmic techniques. PMID- 27699114 TI - Automated, highly reproducible, wide-field, light-based cortical mapping method using a commercial stereo microscope and its applications. AB - We introduce a more flexible optogenetics-based mapping system attached on a stereo microscope, which offers automatic light stimulation to individual regions of interest in the cortex that expresses light-activated channelrhodopsin-2 in vivo. Combining simultaneous recording of electromyography from specific forelimb muscles, we demonstrate that this system offers much better efficiency and precision in mapping distinct domains for controlling limb muscles in the mouse motor cortex. Furthermore, the compact and modular design of the system also yields a simple and flexible implementation to different commercial stereo microscopes, and thus could be widely used among laboratories. PMID- 27699115 TI - Bundled-optode implementation for 3D imaging in functional near-infrared spectroscopy. AB - The paper presents a functional near-infrared spectroscopy (fNIRS)-based bundled optode method for detection of the changes of oxy-hemoglobin (HbO) and deoxy hemoglobin (HbR) concentrations. fNIRS with 32 optodes is utilized to measure five healthy male subjects' brain-hemodynamic responses to arithmetic tasks. Specifically, the coordinates of 256 voxels in the three-dimensional (3D) volume are computed according to the known probe geometry. The mean path length factor in the Beer-Lambert equation is estimated as a function of the emitter-detector distance, which is utilized for computation of the absorption coefficient. The mean values of HbO and HbR obtained from the absorption coefficient are then applied for construction of a 3D fNIRS image. Our results show that the proposed method, as compared with the conventional approach, can detect brain activity with higher spatial resolution. This method can be extended for 3D fNIRS imaging in real-time applications. PMID- 27699116 TI - Measurement of biofilm growth and local hydrodynamics using optical coherence tomography. AB - We report on localized and simultaneous measurement of biofilm growth and local hydrodynamics in a microfluidic channel using optical coherence tomography. We measure independently with high spatio-temporal resolution the longitudinal flow velocity component parallel to the imaging beam and the transverse flow velocity component perpendicular to the imaging beam. Based on the measured velocities we calculate the shear-rates in the flow channel. We show the relation between the measured biofilm structure and flow velocities as biofilm growth progresses over the course of 48 hours. PMID- 27699117 TI - Characterizing fibrosis in UUO mice model using multiparametric analysis of phasor distribution from FLIM images. AB - Phasor approach to fluorescence lifetime microscopy is used to study development of fibrosis in the unilateral ureteral obstruction model (UUO) of kidney in mice. Traditional phasor analysis has been modified to create a multiparametric analysis scheme that splits the phasor points in four equidistance segments based on the height of peak of the phasor distribution and calculates six parameters including average phasor positions, the shape of each segment, the angle of the distribution and the number of points in each segment. These parameters are used to create a spectrum of twenty four points specific to the phasor distribution of each sample. Comparisons of spectra from diseased and healthy tissues result in quantitative separation and calculation of statistical parameters including AUC values, positive prediction values and sensitivity. This is a new method in the evolving field of analyzing phasor distribution of FLIM data and provides further insights. Additionally, the progression of fibrosis with time is detected using this multiparametric approach to phasor analysis. PMID- 27699118 TI - Handheld nonlinear microscope system comprising a 2 MHz repetition rate, mode locked Yb-fiber laser for in vivo biomedical imaging. AB - A novel, Yb-fiber laser based, handheld 2PEF/SHG microscope imaging system is introduced. It is suitable for in vivo imaging of murine skin at an average power level as low as 5 mW at 200 kHz sampling rate. Amplified and compressed laser pulses having a spectral bandwidth of 8 to 12 nm at around 1030 nm excite the biological samples at a ~1.89 MHz repetition rate, which explains how the high quality two-photon excitation fluorescence (2PEF) and second harmonic generation (SHG) images are obtained at the average power level of a laser pointer. The scanning, imaging and detection head, which comprises a conventional microscope objective for beam focusing, has a physical length of ~180 mm owing to the custom designed imaging telescope system between the laser scanner mirrors and the entrance aperture of the microscope objective. Operation of the all-fiber, all normal dispersion Yb-fiber ring laser oscillator is electronically controlled by a two-channel polarization controller for Q-switching free mode-locked operation. The whole nonlinear microscope imaging system has the main advantages of the low price of the fs laser applied, fiber optics flexibility, a relatively small, light-weight scanning and detection head, and a very low risk of thermal or photochemical damage of the skin samples. PMID- 27699119 TI - Whole-body multispectral photoacoustic imaging of adult zebrafish. AB - The zebrafish, an ideal vertebrate for studying developmental biology and genetics, is increasingly being used to understand human diseases, due to its high similarity to the human genome and its optical transparency during embryonic stages. Once the zebrafish has fully developed, especially wild-type breeds, conventional optical imaging techniques have difficulty in imaging the internal organs and structures with sufficient resolution and penetration depth. Even with established mutant lines that remain transparent throughout their life cycle, it is still challenging for purely optical imaging modalities to visualize the organs of juvenile and adult zebrafish at a micro-scale spatial resolution. In this work, we developed a non-invasive three-dimensional photoacoustic imaging platform with an optimized illumination pattern and a cylindrical-scanning-based data collection system to image entire zebrafish with micro-scale resolutions of 80 MUm and 600 MUm in the lateral and axial directions, respectively. In addition, we employed a multispectral strategy that utilized excitation wavelengths from 690 nm to 930 nm to statistically quantify the relative optical absorption spectrum of major organs. PMID- 27699120 TI - Estimation of Jones matrix, birefringence and entropy using Cloude-Pottier decomposition in polarization-sensitive optical coherence tomography. AB - Estimation of polarimetric parameters has been a fundamental issue to assess biological tissues that have form birefringence or polarization scrambling in polarization-sensitive optical coherence tomography (PS-OCT). We present a mathematical framework to provide a maximum likelihood estimation of the target covariance matrix and its incoherent target decomposition to estimate a Jones matrix of a dominant scattering mechanism, called Cloude-Pottier decomposition, thereby deriving the phase retardation and the optic axis of the sample. In addition, we introduce entropy that shows the randomness of the polarization property. Underestimation of the entropy at a low sampling number is mitigated by asymptotic quasi maximum likelihood estimator. A bias of the entropy from random noises is corrected to show only the polarization property inherent in the sample. The theory is validated with experimental measurements of a glass plate and waveplates, and applied to the imaging of a healthy human eye anterior segment as an image filter. PMID- 27699121 TI - Direct visualization of functional heterogeneity in hepatobiliary metabolism using 6-CFDA as model compound. AB - Hepatobiliary metabolism is one of the major functions of the liver. However, little is known of the relationship between the physiological location of the hepatocytes and their metabolic potential. By the combination of time-lapse multiphoton microscopy and first order kinetic constant image analysis, the hepatocellular metabolic rate of the model compound 6-carboxyfluorescein diacetate (6-CFDA) is quantified at the single cell level. We found that the mouse liver can be divided into three zones, each with distinct metabolic rate constants. The sinusoidal uptake coefficients k1 of Zones 1, 2, and 3 are respectively 0.239 +/- 0.077, 0.295 +/- 0.087, and 0.338 +/- 0.133 min-1, the apical excreting coefficients k2 of Zones 1, 2, and 3 are 0.0117 +/- 0.0052, 0.0175 +/- 0.0052, and 0.0332 +/- 0.0195 min-1, respectively. Our results show not only the existence of heterogeneities in hepatobiliary metabolism, but they also show that Zone 3 is the main area of metabolism. PMID- 27699122 TI - Multi-parameter analysis using photovoltaic cell-based optofluidic cytometer. AB - A multi-parameter optofluidic cytometer based on two low-cost commercial photovoltaic cells and an avalanche photodetector is proposed. The optofluidic cytometer is fabricated on a polydimethylsiloxane (PDMS) substrate and is capable of detecting side scattered (SSC), extinction (EXT) and fluorescence (FL) signals simultaneously using a free-space light transmission technique without the need for on-chip optical waveguides. The feasibility of the proposed device is demonstrated by detecting fluorescent-labeled polystyrene beads with sizes of 3 MUm, 5 MUm and 10 MUm, respectively, and label-free beads with a size of 7.26 MUm. The detection experiments are performed using both single-bead population samples and mixed-bead population samples. The detection results obtained using the SSC/EXT, EXT/FL and SSC/FL signals are compared with those obtained using a commercial flow cytometer. It is shown that the optofluidic cytometer achieves a high detection accuracy for both single-bead population samples and mixed-bead population samples. Consequently, the proposed device provides a versatile, straightforward and low-cost solution for a wide variety of point-of-care (PoC) cytometry applications.

AB - We report on a miniature label-free imaging system for monitoring brain blood flow and blood oxygenation changes in awake, freely behaving rats. The device, weighing 15 grams, enables imaging in a ~ 2 * 2 mm field of view with 4.4 MUm lateral resolution and 1 - 8 Hz temporal sampling rate. The imaging is performed through a chronically-implanted cranial window that remains optically clear between 2 to > 6 weeks after the craniotomy. This imaging method is well suited for longitudinal studies of chronic models of brain diseases and disorders. In this work, it is applied to monitoring neurovascular coupling during drug-induced absence-like seizures 6 weeks following the craniotomy. PMID- 27699125 TI - High-resolution real-time dual-view imaging with multiple point of view microscopy. AB - Most methods to observe three-dimensional processes in living samples are based on imaging a single plane that is sequentially scanned through the sample. Sequential scanning is inherently slow, which can make it difficult to capture objects moving quickly in three dimensions. Here we present a novel method, multiple point-of-view microscopy (MPoVM), that allows simultaneous capturing of the front and side views of a sample with high resolution. MPoVM can be implemented in most fluorescence microscopes, offering new opportunities in the study of dynamic biological processes in three dimensions. PMID- 27699124 TI - Chemotherapeutic drug-specific alteration of microvascular blood flow in murine breast cancer as measured by diffuse correlation spectroscopy. AB - The non-invasive, in vivo measurement of microvascular blood flow has the potential to enhance breast cancer therapy monitoring. Here, longitudinal blood flow of 4T1 murine breast cancer (N=125) under chemotherapy was quantified with diffuse correlation spectroscopy based on layer models. Six different treatment regimens involving doxorubicin, cyclophosphamide, and paclitaxel at clinically relevant doses were investigated. Treatments with cyclophosphamide increased blood flow as early as 3 days after administration, whereas paclitaxel induced a transient blood flow decrease at 1 day after administration. Early blood flow changes correlated strongly with the treatment outcome and distinguished treated from untreated mice individually for effective treatments. PMID- 27699126 TI - Preclinical photoacoustic models: application for ultrasensitive single cell malaria diagnosis in large vein and artery. AB - In vivo photoacoustic flow cytometry (PAFC) has demonstrated potential for early diagnosis of deadly diseases through detection of rare circulating tumor cells, pathogens, and clots in nearly the entire blood volume. Before clinical application, this promising diagnostic platform requires verification and optimization using adequate preclinical models. We show here that this can be addressed by examination of large mouse blood vessels which are similar in size, depth and flow velocity to human vessels used in PAFC. Using this model, we verified the capability of PAFC for ultrasensitive, noninvasive, label-free, rapid malaria diagnosis. The time-resolved detection of delayed PA signals from deep vessels provided complete elimination of background from strongly pigmented skin. We discovered that PAFC's sensitivity is higher during examination of infected cells in arteries compared to veins at similar flow rate. Our advanced PAFC platform integrating a 1060 nm laser with tunable pulse rate and width, a wearable probe with a focused transducer, and linear and nonlinear nanobubble amplified signal processing demonstrated detection of parasitemia at the unprecedented level of 0.00000001% within 20 seconds and the potential to further improve the sensitivity 100-fold in humans, that is approximately 106 times better than in existing malaria tests. PMID- 27699127 TI - Assessment of a multi-layered diffuse correlation spectroscopy method for monitoring cerebral blood flow in adults. AB - Diffuse correlation spectroscopy (DCS) is a promising technique for brain monitoring as it can provide a continuous signal that is directly related to cerebral blood flow (CBF); however, signal contamination from extracerebral tissue can cause flow underestimations. The goal of this study was to investigate whether a multi-layered (ML) model that accounts for light propagation through the different tissue layers could successfully separate scalp and brain flow when applied to DCS data acquired at multiple source-detector distances. The method was first validated with phantom experiments. Next, experiments were conducted in a pig model of the adult head with a mean extracerebral tissue thickness of 9.8 +/- 0.4 mm. Reductions in CBF were measured by ML DCS and computed tomography perfusion for validation; excellent agreement was observed by a mean difference of 1.2 +/- 4.6% (CI95%: -31.1 and 28.6) between the two modalities, which was not significantly different. PMID- 27699128 TI - Unconstrained pulse pressure monitoring for health management using hetero-core fiber optic sensor. AB - In this paper, we present a pulse pressure waveform sensor that does not constrain a wearer's daily activity; the sensor uses hetero-core fiber optics. Hetero-core fiber sensors have been found to be sensitive to moderate bending. To detect minute pulse pressure changes from the radial artery at the wrist, we devised a fiber sensor arrangement using three-point bending supports. We analyzed and evaluated the measurement validity using wavelet transformation, which is well-suited for biological signal processing. It was confirmed that the detected pulse waveform had a fundamental mode frequency of around 1.25 Hz over the time-varying waveform. A band-pass filter with a range of frequencies from 0.85 to 1.7 Hz was used to pick up the fundamental mode. In addition, a high-pass filter with 0.85 Hz frequency eliminated arm motion artifacts; consequently, we achieved high signal-to-noise ratio. For unrestricted daily health management, it is desirable that pulse pressure monitoring can be achieved by simply placing a device on the hand without the sensor being noticed. Two types of arrangements were developed and demonstrated in which the pulse sensors were either embedded in a base, such as an armrest, or in a wearable device. A wearable device without cuff pressure using a sensitivity-enhanced fiber sensor was successfully achieved with a sensitivity of 0.07-0.3 dB with a noise floor lower than 0.01 dB for multiple subjects. PMID- 27699129 TI - Motion quantification during multi-photon functional imaging in behaving animals. AB - Functional imaging in behaving animals is essential to understanding brain function. However, artifacts resulting from animal motion, including locomotion, can severely corrupt functional measurements. To dampen tissue motion, we designed a new optical window with minimal optical aberrations. Using the newly developed high-speed continuous volumetric imaging system based on an optical phase-locked ultrasound lens, we quantified motion of the cerebral cortex and hippocampal surface during two-photon functional imaging in behaving mice. We find that the out-of-plane motion is generally greater than the axial dimension of the point-spread-function during mouse locomotion, which indicates that high speed continuous volumetric imaging is necessary to minimize motion artifacts. PMID- 27699130 TI - Pencil beam all-optical ultrasound imaging. AB - A miniature, directional fibre-optic acoustic source is presented that employs geometrical focussing to generate a nearly-collimated acoustic pencil beam. When paired with a fibre-optic acoustic detector, an all-optical ultrasound probe with an outer diameter of 2.5 mm is obtained that acquires a pulse-echo image line at each probe position without the need for image reconstruction. B-mode images can be acquired by translating the probe and concatenating the image lines, and artefacts resulting from probe positioning uncertainty are shown to be significantly lower than those observed for conventional synthetic aperture scanning of a non-directional acoustic source. The high image quality obtained for excised vascular tissue suggests that the all-optical ultrasound probe is ideally suited for in vivo, interventional applications. PMID- 27699131 TI - Real-time in vivo diagnosis of laryngeal carcinoma with rapid fiber-optic Raman spectroscopy. AB - We assess the clinical utility of a unique simultaneous fingerprint (FP) (i.e., 800-1800 cm-1) and high-wavenumber (HW) (i.e., 2800-3600 cm-1) fiber-optic Raman spectroscopy for in vivo diagnosis of laryngeal cancer at endoscopy. A total of 2124 high-quality in vivo FP/HW Raman spectra (normal = 1321; cancer = 581) were acquired from 101 tissue sites (normal = 71; cancer = 30) of 60 patients (normal = 44; cancer = 16) undergoing routine endoscopic examination. FP/HW Raman spectra differ significantly between normal and cancerous laryngeal tissue that could be attributed to changes of proteins, lipids, nucleic acids, and the bound water content in the larynx. Partial least squares-discriminant analysis and leave-one tissue site-out, cross-validation were employed on the in vivo FP/HW tissue Raman spectra acquired, yielding a diagnostic accuracy of 91.1% (sensitivity: 93.3% (28/30); specificity: 90.1% (64/71)) for laryngeal cancer identification, which is superior to using either FP (accuracy: 86.1%; sensitivity: 86.7% (26/30); specificity: 85.9% (61/71)) or HW (accuracy: 84.2%; sensitivity: 76.7% (23/30); specificity: 87.3% (62/71)) Raman technique alone. Further receiver operating characteristic analysis reconfirms the best performance of the simultaneous FP/HW Raman technique for laryngeal cancer diagnosis. We demonstrate for the first time that the simultaneous FP/HW Raman spectroscopy technique can be used for improving real-time in vivo diagnosis of laryngeal carcinoma during endoscopic examination. PMID- 27699132 TI - 3D imaging in CUBIC-cleared mouse heart tissue: going deeper. AB - The ability to acquire high resolution 3D images of the heart enables to study heart diseases more in detail. In this work, the CUBIC (clear, unobstructed brain imaging cocktails and computational analysis) clearing protocol was optimized for thick mouse heart sections to enhance the penetration depth of the confocal microscope lasers into the tissue. In addition, the optimized CUBIC clearing of the heart enhances antibody penetration into the tissue by a factor of five. The present protocol enables deep 3D high-quality image acquisition in the heart allowing a much more accurate assessment of the cellular and structural changes that underlie heart diseases. PMID- 27699133 TI - Classification of basal cell carcinoma in human skin using machine learning and quantitative features captured by polarization sensitive optical coherence tomography. AB - We report the first fully automated detection of basal cell carcinoma (BCC), the most commonly occurring type of skin cancer, in human skin using polarization sensitive optical coherence tomography (PS-OCT). Our proposed automated procedure entails building a machine-learning based classifier by extracting image features from the two complementary image contrasts offered by PS-OCT, intensity and phase retardation (PR), and selecting a subset of features that yields a classifier with the highest accuracy. Our classifier achieved 95.4% sensitivity and specificity, validated by leave-one-patient-out cross validation (LOPOCV), in detecting BCC in human skin samples collected from 42 patients. Moreover, we show the superiority of our classifier over the best possible classifier based on features extracted from intensity-only data, which demonstrates the significance of PR data in detecting BCC. PMID- 27699134 TI - Full-field interferometry for counting and differentiating aquatic biotic nanoparticles: from laboratory to Tara Oceans. AB - There is a huge abundance of viruses and membrane vesicles in seawater. We describe a new full-field, incoherently illuminated, shot-noise limited, common path interferometric detection method that we couple with the analysis of Brownian motion to detect, quantify, and differentiate biotic nanoparticles. We validated the method with calibrated nanoparticles and homogeneous DNA or RNA viruses. The smallest virus size that we characterized with a suitable signal-to noise ratio was around 30 nm in diameter. Analysis of Brownian motions revealed anisotropic trajectories for myoviruses.We further applied the method for vesicles detection and for analysis of coastal and oligotrophic samples from Tara Oceans circumnavigation. PMID- 27699135 TI - Imaging in turbid media: a transmission detector gives 2-3 order of magnitude enhanced sensitivity compared to epi-detection schemes. AB - Imaging depth in turbid media by two-photon fluorescence microscopy depends on the ability of the optical system to detect weak fluorescence signals. We have shown that use of a wide area detector in transmission geometry allows increasing imaging depth in turbid media due to efficient photon collection. Compared to the conventional epi-detection scheme used in most commercial microscopes, the transmission detector was found to be 2-3 orders of magnitude more sensitive when used for in depth imaging in scattering samples simulating brain optical properties. PMID- 27699136 TI - Terahertz transmission vs reflection imaging and model-based characterization for excised breast carcinomas. AB - This work presents experimental and analytical comparison of terahertz transmission and reflection imaging modes for assessing breast carcinoma in excised paraffin-embedded human breast tissue. Modeling for both transmission and reflection imaging is developed. The refractive index and absorption coefficient of the tissue samples are obtained. The reflection measurements taken at the system's fixed oblique angle of 30 degrees are shown to be a hybridization of TE and TM modes. The models are validated with transmission spectroscopy at fixed points on fresh bovine muscle and fat tissues. Images based on the calculated absorption coefficient and index of refraction of bovine tissue are successfully compared with the terahertz magnitude and phase measured in the reflection mode. The validated techniques are extended to 20 and 30 MUm slices of fixed human lobular carcinoma and infiltrating ductal carcinoma mounted on polystyrene microscope slides in order to investigate the terahertz differentiation of the carcinoma with non-cancerous tissue. Both transmission and reflection imaging show clear differentiation in carcinoma versus healthy tissue. However, when using the reflection mode, in the calculation of the thin tissue properties, the absorption is shown to be sensitive to small phase variations that arise due to deviations in slide and tissue thickness and non-ideal tissue adhesion. On the other hand, the results show that the transmission mode is much less sensitive to these phase variations. The results also demonstrate that reflection imaging provides higher resolution and more clear margins between cancerous and fibroglandular regions, cancerous and fatty regions, and fibroglandular and fatty tissue regions. In addition, more features consistent with high power pathology images are exhibited in the reflection mode images. PMID- 27699137 TI - Time resolved diffuse optical spectroscopy with geometrically accurate models for bulk parameter recovery. AB - A novel straightforward, accessible and efficient approach is presented for performing hyperspectral time-domain diffuse optical spectroscopy to determine the optical properties of samples accurately using geometry specific models. To allow bulk parameter recovery from measured spectra, a set of libraries based on a numerical model of the domain being investigated is developed as opposed to the conventional approach of using an analytical semi-infinite slab approximation, which is known and shown to introduce boundary effects. Results demonstrate that the method improves the accuracy of derived spectrally varying optical properties over the use of the semi-infinite approximation. PMID- 27699138 TI - Procedures for risk-stratification of lung cancer using buccal nanocytology. AB - Lung cancer is the leading cause of cancer deaths in the U.S. with survival dramatically depending on stage at diagnosis. We had earlier reported that nanocytology of buccal cells can accurately risk-stratify smokers for the presence of early and late-stage lung cancer. To translate the technique into clinical practice, standardization of operating procedures is necessary to consistently yield precise and repeatable results. Here, we develop and validate simple, robust, and easily implementable procedures for specimen collection, processing, etc. in addition to a commercially-viable instrument prototype. Results of this work enable translation of the technology from academic lab to physicians' office. PMID- 27699139 TI - Targeted Theranostic Approach for Glioma Using Dendrimer-Based Curcumin Nanoparticle. AB - The delivery of anti-cancer agents to brain tumors represent a challenge because the blood-brain tumor barrier (BBTB) effectively limits the delivery of many agents. A new generation 3 (G3) dendrimer-based curcumin (Curc) conjugate was synthesized. The synthesized G3-Curc conjugate demonstrated full solubility in aqueous media. The in vitro study revealed that G3-Curc nanoparticles were internalized into glioma U-251 cells. Systemic delivery of G3-Curc conjugate led to preferentially accumulation in an orthotopic preclinical glioma model minimizing systemic toxic effect. Multicolor microscopy images of the tumor tissue showed that G3-Curc particles were internalized inside tumor cells selectively and further localized within nuclei. Enhanced bioavailability of G3 Curc conjugate was also observed with improved therapeutic efficacy against different cancers cells. PMID- 27699140 TI - An Orbital Malignant Melanoma Arising in Cellular Blue Nevus in a Patient with Nevus of Ota. AB - Melanomas arising from orbital melanocytic proliferations are exceedingly rare. Many questions remain regarding their development and malignant transformation. We report on a 45-year-old Caucasian woman with a nevus of Ota that presented with visual disturbances involving her right eye and was found to have a biopsy proven cellular blue nevus in the orbital space. Five years later, she presented with proptosis and worsening symptoms. Biopsy at that time showed a cellular blue nevus with areas of melanoma. We conclude that patients with a nevus of Ota or an orbital cellular blue nevus, particularly Caucasians, should be monitored for ocular/orbital involvement and followed closely for signs of rapid growth. There may be a progressive evolution to melanoma from a blue nevus. PMID- 27699141 TI - Post-Treatment Gliosarcoma Extension into the Pterygomaxillary Fossa: Literature Review and Case Report. AB - Only four primary gliosarcoma case reports are described in the literature with transcranial (intradural to extradural) penetration into the region of the infratemporal fossa. This is the first report of a primary glioblastoma (GBM) that evolved into secondary or post-treatment gliosarcoma without evidence of a second de novo tumor and with extension into the left pterygomaxillary fossa. PMID- 27699142 TI - Persistence of a Cervical Neck Mass, Not Just the Lymphoma. AB - Actinomycosis is a rare, chronic granulomatous infection caused by gram-positive, anaerobic to microaerophilic branching filamentous bacteria. In the cervicofacial region, it usually presents as an enlarging neck mass. It remains a diagnostic challenge due to the fact that cultures show no growth in more than 50% of cases. We report a case of a 67-year-old patient known to have a neck mass secondary to lymphoma in which the neck mass persisted despite therapy. Upon evaluation, the diagnosis of culture-negative actinomycosis was based on histopathology findings, and the patient received antibiotic therapy. We will discuss the diagnosis and pathology of actinomycosis, attempting to explore the relationship between actinomycosis and lymphoid malignancy. PMID- 27699144 TI - Identifying metabolic syndrome in a clinical cohort: Implications for prevention of chronic disease. AB - In the clinical setting, calculating cardiovascular disease (CVD) risk is commonplace but the utility of the harmonised equation for metabolic syndrome (MetS) (Alberti et al., 2009) is less well established. The aims of this study were to apply this equation to an overweight clinical cohort to identify risk factors for being metabolically unhealthy and explore associations with chronic disease. Baseline data were analysed from a lifestyle intervention trial of Illawarra residents recruited in 2014/2015. Participants were aged 25-54 years with a BMI 25-40 kg/m2. Data included MetS, CVD risk, insulin sensitivity, weight, body fat, diet, peripheral artery disease (PAD), physical activity, socio economic position and psychological profile. Backward stepwise regression tested the association of covariates with MetS status and linear or logistic regression tested associations between MetS and risk of CVD, coronary heart disease, PAD and insulin resistance. 374 participants were included in the analysis with 127 (34.0%) categorised with MetS. Covariates significantly and positively associated with MetS were higher BMI (odds 1.26, p < 0.01) and older age (odds 1.08, p < 0.01). MetS participants (n = 351) had a 4.50% increase in CVD risk and were 8.1 and 12.7 times (respectively) more likely to be at risk of CHD and insulin resistance, compared to participants without MetS. The utility of the harmonised equation in the clinical setting was confirmed in this overweight clinical cohort. Those classified as having MetS were more likely to be older, overweight/obese individuals and they had a substantially higher risk of developing CVD and insulin resistance than those without MetS. PMID- 27699143 TI - Photoacoustic Flow Cytometry for Single Sickle Cell Detection In Vitro and In Vivo. AB - Control of sickle cell disease (SCD) stage and treatment efficiency are still time-consuming which makes well-timed prevention of SCD crisis difficult. We show here that in vivo photoacoustic (PA) flow cytometry (PAFC) has a potential for real-time monitoring of circulating sickled cells in mouse model. In vivo data were verified by in vitro PAFC and photothermal (PT) and PA spectral imaging of sickle red blood cells (sRBCs) expressing SCD-associated hemoglobin (HbS) compared to normal red blood cells (nRBCs). We discovered that PT and PA signal amplitudes from sRBCs in linear mode were 2-4-fold lower than those from nRBCs. PT and PA imaging revealed more profound spatial hemoglobin heterogeneity in sRBCs than in nRBCs, which can be associated with the presence of HbS clusters with high local absorption. This hypothesis was confirmed in nonlinear mode through nanobubble formation around overheated HbS clusters accompanied by spatially selective signal amplification. More profound differences in absorption of sRBCs than in nRBCs led to notable increase in PA signal fluctuation (fluctuation PAFC mode) as an indicator of SCD. The obtained data suggest that noninvasive label-free fluctuation PAFC has a potential for real-time enumeration of sRBCs both in vitro and in vivo. PMID- 27699145 TI - The relationship between physical activity, sleep duration and depressive symptoms in older adults: The English Longitudinal Study of Ageing (ELSA). AB - Research to date suggests that physical activity (PA) is associated with distinct aspects of sleep, but studies have predominantly focused on sleep quality, been carried out in younger adults, and have not accounted for many covariates. Of particular interest is also the reported relationship between physical activity and depression in older adults and as such, their associations with sleep duration. Here we examine the cross-sectional relation between physical activity and sleep duration in a community-dwelling sample of 5265 older adults from the English Longitudinal Study of Ageing. We analysed the data using multiple regression, with physical activity as a categorical exposure and sleep duration a continuous outcome, as well as testing the interaction between physical activity and depressive symptoms, which was significant (p < 0.001). We therefore stratified our analyses by depressive symptomatology. Our main finding was that, in the group with elevated depressive symptoms only, physical activity was positively associated with sleep duration in models adjusted for all covariates (age, sex, wealth, ethnicity, smoking, alcohol consumption, BMI, long-standing illness) across low [B (mean difference in sleep duration) = 25.22 min, 95% CI = (3.72; 46.72)], moderate [B = 27.92 min, 95% CI = (6.59; 49.26)] and high [B = 31.65 min, 95% CI = (7.36; 55.94)] PA groups, in comparison to the sedentary group. However, we observed no relation between physical activity and sleep duration in respondents who reported no depressive symptoms, irrespective of physical activity level (p > 0.05). Our findings suggest that a potentially effective way of improving sleep in older adults with depressive symptoms is via physical activity interventions.

PMID- 27699147 TI - Onychomycosis due to Chaetomium globosum with yellowish black discoloration and periungual inflammation. AB - Onychomycosis is usually caused by dermatophytes, although also other filamentous and yeast-like fungi are associated with nail invasion. Chaetomium is an environmental genus of ascomycetes exhibiting a certain degree of extremotolerance. We report the first case of onychomycosis in a 46-year-old woman in China caused by Chaetomium globosum. The patient showed yellowish black discoloration with periungual inflammation on the left first toenail. We confirmed the causative agent, C. globosum, by KOH mount, culture, micromorphology and DNA sequence analysis. PMID- 27699149 TI - Expression of P40 and P63 in lung cancers using fine needle aspiration cases. Understanding clinical pitfalls and limitations. AB - BACKGROUND: Fine-needle aspiration (FNA) biopsy of lung lesions is a highly accurate method for diagnosing and staging of lung cancers, particularly in patients with advanced cancer. Although, the majority of FNA cases of non-small cell lung carcinoma (NSCLC) can be subclassified by hematoxylin and eosin (H&E) sections, immunohistochemical (IHC) markers are usually necessary for difficult cases. Our previous study has shown that both P40 and P63 demonstrate differential sensitivity and specificity in the subclassification of squamous cell carcinoma (SqCC) using tumor tissue microarrays (TMA). In the present study, we further evaluated the utility of P40 and P63 and the potential pitfalls and limitations associated with the usefulness of these stains in FNA cases. METHODS: By a computer search of pathology archives, 144 FNA biopsies with diagnoses of lung cancers and P40/P63 stains were identified, including 50 adenocarcinomas (ADCs), 56 SqCCs, 8 small cell lung carcinomas (SCLCs), and 12 cases of poorly differentiated carcinoma (PD CA). Ten benign FNA lung lesions and 8 other malignant neoplasms were also included as controls. Nuclear staining patterns of P40 and P63 were scored semi-quantitatively as 0 (negative), 1 (<10%, weak and focal), or 2 (>10%, strong and diffuse). RESULTS: In lung SqCCs, P40 and P63 were positive in 77.3% and 89.5% cases, respectively. In ADCs, P40 was weakly and focally positive in 6.1% cases, and P63 was variably positive in 62.8% cases. In SCLCs, P40 and P63 were focally positive in 12.5% and 50% cases. In PD CAs, no P40 or P63 immunoreactivity was detected. In the group of other neoplasms (n=8) both P40 and P63 were positive in the case of metastatic non-seminomatous germ cell tumor (NSGCT) (n=1), and P63 was positive in the case of metastatic Merkel cell carcinoma (n=1). The sensitivity and specificity of P40 and P63 were 76.9%/93.3%, and 90.2%/50.7% in the lung SqCC. CONCLUSIONS: P63 has a better sensitivity, and P40 has a better specificity for SqCC. A positive staining pattern with both markers was also found in certain non-SqCC cases. Recognizing limitations of these markers are particularly important in FNA cases. PMID- 27699150 TI - Draft genome sequence of Microbacterium oleivorans strain Wellendorf implicates heterotrophic versatility and bioremediation potential. AB - Microbacterium oleivorans is a predominant member of hydrocarbon-contaminated environments. We here report on the genomic analysis of M. oleivorans strain Wellendorf that was isolated from an indoor door handle. The partial genome of M. oleivorans strain Wellendorf consists of 2,916,870 bp of DNA with 2831 protein coding genes and 49 RNA genes. The organism appears to be a versatile mesophilic heterotroph potentially capable of hydrolysis a suite of carbohydrates and amino acids. Genomic analysis revealed metabolic versatility with genes involved in the metabolism and transport of glucose, fructose, rhamnose, galactose, xylose, arabinose, alanine, aspartate, asparagine, glutamate, serine, glycine, threonine and cysteine. This is the first detailed analysis of a Microbacterium oleivorans genome. PMID- 27699148 TI - Effects of craving behavioral intervention on neural substrates of cue-induced craving in Internet gaming disorder. AB - Internet gaming disorder (IGD) is characterized by high levels of craving for online gaming and related cues. Since addiction-related cues can evoke increased activation in brain areas involved in motivational and reward processing and may engender gaming behaviors or trigger relapse, ameliorating cue-induced craving may be a promising target for interventions for IGD. This study compared neural activation between 40 IGD and 19 healthy control (HC) subjects during an Internet gaming cue-reactivity task and found that IGD subjects showed stronger activation in multiple brain areas, including the dorsal striatum, brainstem, substantia nigra, and anterior cingulate cortex, but lower activation in the posterior insula. Furthermore, twenty-three IGD subjects (CBI + group) participated in a craving behavioral intervention (CBI) group therapy, whereas the remaining 17 IGD subjects (CBI - group) did not receive any intervention, and all IGD subjects were scanned during similar time intervals. The CBI + group showed decreased IGD severity and cue-induced craving, enhanced activation in the anterior insula and decreased insular connectivity with the lingual gyrus and precuneus after receiving CBI. These findings suggest that CBI is effective in reducing craving and severity in IGD, and it may exert its effects by altering insula activation and its connectivity with regions involved in visual processing and attention bias. PMID- 27699152 TI - Immunologic factors may play a role in herpes simplex virus 1 reactivation in the brain and retina after influenza vaccination. AB - Herpes simplex virus 1 (HSV-1) is a nearly ubiquitous human pathogen, remaining dormant in its human host the majority of the time. The interaction between HSV-1 and the immune system represents a complicated balance of power that allows the virus to persist in the host for a lifetime. However, disruptions in the immune system can activate the virus with the potential to cause devastating infections in the central nervous system (CNS). We present a patient who suffered three consecutive yearly HSV-1 CNS episodes (encephalitis, seizure, and retinitis), each within days of his influenza vaccination. We highlight subtle immunologic defects in this patient that may have allowed unchecked viral replication and resultant disease manifestations, as well as the potential role of influenza vaccine in tipping this balance in favor of HSV-1. PMID- 27699151 TI - Draft genome sequence and detailed analysis of Pantoea eucrina strain Russ and implication for opportunistic pathogenesis. AB - The genus Pantoea is a predominant member of host-associated microbiome. We here report on the genomic analysis of Pantoea eucrina strain Russ that was isolated from a trashcan at Oklahoma State University, Stillwater, OK. The draft genome of Pantoea eucrina strain Russ consists of 3,939,877 bp of DNA with 3704 protein coding genes and 134 RNA genes. This is the first report of a genome sequence of a member of Pantoea eucrina. Genomic analysis revealed metabolic versatility with genes involved in the metabolism and transport of all amino acids as well as glucose, fructose, mannose, xylose, arabinose and galactose, suggesting the organism is a versatile heterotroph. The genome also encodes an extensive secretory machinery including types I, II, III, IV, and Vb secretion systems, and several genes for pili production including the new usher/chaperone system (pfam 05,229). The implications of these systems for opportunistic pathogenesis are discussed. PMID- 27699153 TI - Bone mineral density in mucopolysaccharidosis IVB. AB - To date, the only published reports of bone mineral density (BMD) in MPS IV involve patients with MPS IVA; no reports exist describing BMD for MPS IVB. In this prospective study of BMD in three patients with MPS IVB, BMD was acquired by dual-energy X-ray absorptiometry (DXA) at whole body (WB), lumbar spine (LS), and lateral distal femur (LDF). Functional abilities, ambulatory status, medical history, and height z-score were evaluated. Three patients with MPS IVB (two females), aged 17.7, 31.4 and 31.7 years, were evaluated. Every patient was ambulatory and one sustained two fractures caused by trauma. Whole body and hip DXA scans were technically invalid in every patient due to the presence of prosthetic hip hardware. Lumbar spine was valid in only 1 patient due skeletal abnormalities, and was normal (Z-score of - 0.8). The LDF was valid in every patient and was low at all three regions of interest: average LDF z-scores were - 3.1 (range, - 2.9 to - 3.6), - 2.3 (range, - 2.0 to - 2.5), and - 2.1 (range, - 2.0 to - 2.3) for region 1-region 3, respectively. Patients with MPS IVB have low BMD of the lower extremities even with full-time ambulation. Routine body sites to measure by DXA were problematic; hip and WB were invalid due to artifact, and LS had limited utility. The LDF was the only body site consistently available on all patients. Patients did not experience low-energy fractures despite low BMD. PMID- 27699154 TI - Methylmalonyl-coA epimerase deficiency: A new case, with an acute metabolic presentation and an intronic splicing mutation in the MCEE gene. AB - Methylmalonyl-coA epimerase (MCE) follows propionyl-coA carboxylase and precedes methylmalonyl-coA mutase in the pathway converting propionyl-coA to succinyl-coA. MCE deficiency has previously been described in six patients, one presenting with metabolic acidosis, the others with nonspecific neurological symptoms or asymptomatic. The clinical significance and biochemical characteristics of this rare condition have been incompletely defined. We now describe a patient who presented acutely at 5 years of age with vomiting, dehydration, confusion, severe metabolic acidosis and mild hyperammonemia. At presentation, organic acid profiles were dominated by increased ketones and 3-hydroxypropionate, with moderately elevated methylcitrate and propionylglycine, and acylcarnitine profiles showed marked C3 (propionylcarnitine) elevation with normal C4DC (methylmalonylcarnitine + succinylcarnitine). Propionic acidemia was initially suspected, but it was subsequently noted that methylmalonic acid was mildly but persistently elevated in urine, and clearly elevated in plasma and cerebrospinal fluid. The overall biochemical profile prompted consideration of MCE deficiency. Studies on cultured fibroblasts showed moderately decreased propionate incorporation. Complementation analysis permitted assignment to the MCEE group. A heterozygous p.Arg47Ter (p.R47*) mutation in the MCEE gene was identified by sequencing of exons, and RNA studies identified a novel intronic splicing mutation, c.379-644A > G, confirming the diagnosis of MCE deficiency. Following the initial severe presentation, development has been normal and the clinical course over the subsequent six years has remained relatively uneventful on an essentially normal diet. This report contributes to the clinical and biochemical characterisation of this rare disorder, while highlighting potential causes of under-diagnosis or of diagnostic confusion.

PMID- 27699157 TI - Association of Nitric Oxide Levels and Endothelial Nitric Oxide Synthase G894T Polymorphism with Coronary Artery Disease in the Iranian Population. AB - PURPOSE: The endothelial nitric oxide synthase (eNOS) G894T polymorphism has been reported to cause endothelial dysfunction and may have a role in the development of coronary artery disease (CAD). The aim of the present study was to investigate the association of eNOS G894T genetic polymorphism and plasma levels of nitric oxide (NO) with CAD risk in an Iranian population. MATERIALS AND METHODS: We studied 200 patients with angiographically documented CAD and 100 matched controls. Analysis of G894T genetic polymorphism of eNOS was performed by polymerase chain reaction-restriction fragment length polymorphism method. Plasma levels of NO were determined using Griess method. Biochemical analysis was conducted by routine colorimetric methods. RESULTS: Plasma levels of NO were significantly lower in CAD patients than control subjects (41.60+/-12.70 vs. 55.48+/-16.57, P=0.001). Also, the mean plasma levels of NO were significantly lower in T allele carriers of eNOS G894T polymorphism than G allele carriers (P<0.001). The genotype distribution and minor T allele frequency of eNOS G894T polymorphism significantly differed between CAD patients and control subjects (P<0.05). However, no significant association was found between the eNOS G894T polymorphism and the severity of CAD (number of diseased vessel) or the lipid profile of CAD patients (P>0.05). CONCLUSION: Reduced plasma level of NO is associated with increased risk of CAD in our population. Moreover, eNOS G894T polymorphism is a significant risk factor for CAD development via reducing the plasma levels of NO. However, eNOS G894T polymorphism is not a contributing factor for the severity of CAD. PMID- 27699158 TI - Outcomes of Arteriovenous Fistula for Hemodialysis in Pediatric and Adolescent Patients. AB - PURPOSE: This retrospective review aimed to report the outcomes of arteriovenous fistula (AVF) and to evaluate the suitability of AVF as a permanent vascular access in pediatric populations. MATERIALS AND METHODS: Data were collected for all patients aged 0 to 19 years who underwent AVF creation for hemodialysis between January 2000 and June 2014. RESULTS: Fifty-two AVFs were created in 47 patients. Mean age was 15.7+/-3.2 years and mean body weight was 46.7+/-15.4 kg. Of the 52 AVFs, 43 were radiocephalic AVFs, 7 were brachiocephalic AVFs and 2 were basilic vein transpositions. With a mean follow-up of 49.7+/-39.2 months, primary patency was 60.5%, 51.4%, and 47.7% at 1, 3, and 5 years, respectively and secondary patency was 82.7%, 79.2% and 79.2% at 1, 3, and 5 years, respectively. Age, body weight, AVF type, the presence of a central venous catheter, use of anticoagulation therapy, and history of vascular access failure were not significantly associated with patency rates. There were 9 cases (17.3%) of primary failure; low body weight was an independent predictor. Excluding cases of primary failure, the mean duration of maturation was 10.0+/-3.7 weeks. During follow-up, 20 patients (42.6%) underwent kidney transplantation, with a median interval to transplantation of 36 months. CONCLUSION: AVF creation in children and adolescents is associated with acceptable long-term durability, primary failure rate and maturation time. Considering the waiting time and limited kidney graft survival, placement of AVFs should be considered primarily even in patients expected to receive transplantation. PMID- 27699159 TI - Bilateral Type IIIa Endoleak and Disconnection of Both Limbs after Evar with an Endurant II Endograft. AB - A 75-year-old patient with severe comorbidities was treated with an Endurant(r) (Medtronic, USA) II endograft due to a ruptured abdominal aortic aneurysm (AAA). After four years of unremarkable follow-up, bilateral limb separation was detected. The patient underwent endovascular bridging without any complication. Although rarely detected in newer grafts, late bilateral type IIIa endoleaks can present and should be promptly repaired. Complex or ruptured AAAs treated with off-label use of endografts should be under closer surveillance using imaging tools for potential endoleaks or aneurysm sac growth. PMID- 27699160 TI - Cystic Disease of the Groin Presenting as Compression of a Femoral Vessel. AB - In this study, we describe our diagnosis and treatment of two patients who presented with femoral vessel compression caused by a cystic lesion in the groin. One case was diagnosed as adventitial cystic disease (ACD) of the common femoral artery resulting in leg claudication and the other was diagnosed as a ganglion cyst (GC) causing femoral vein compression and unilateral leg swelling. The operative findings differed between these two cases with respect to the dissection of the cyst and femoral vessel, but the postoperative histological examination results were similar. The pathogenesis of ACD and GC is not fully understood, and further investigation is needed to delineate the exact pathology of these uncommon conditions. PMID- 27699161 TI - Intensive Long Distance Running as a Possible Cause of Multiple Splanchnic Arterial Aneurysms: A Case Report. AB - This is a case report that suggests the possible association between multiple splanchnic arterial aneurysms and long-distance running. The clinical features of one patient admitted at Chungbuk National University Hospital for treatment of multiple splanchnic arterial aneurysms were reviewed. A 54-year-old man had a recurrent, intermittent and epigastric pain for 2 months. There was no abnormality in gastroscopy and colonoscopy. An abdominal computed tomography angiography documented calcified superior mesenteric artery (SMA) and splenic artery aneurysms. The patient had a history of recreational long-distance running for over 10 years. His average running time per week was more than 10 hours. There was no evidence of systemic arteritis, connective tissue disorder or infectious process that may have caused the aneurysms. He did not take any drugs. The SMA aneurysm was opened, and the aneurysmal segment of SMA was replaced with a vein graft. The splenic aneurysm was observed. The patient recovered without any sequelae. PMID- 27699162 TI - Bovine Aortic Arch and Bilateral Retroesophageal Course of Common Carotid Arteries in a Symptomatic Patient. AB - Anatomical variations of carotid arteries may be related to their development (agenesis, aplasia, hypoplasia) or course (coiling, kinking, tortuosity). Partial or total aberrancies in carotid vessel anatomy rarely occur. We describe the case of a 95-year-old woman presented with sudden onset of confusion and disorientation together with upper limb clonus. Computed tomography (CT)-scan revealed a left frontal brain injury with a not conclusive carotid doppler ultrasound. CT angiography reported a bovine aortic arch with bilateral retroesophageal course of both common carotid arteries and left severe (>70%) internal carotid artery stenosis. The knowledge of anatomical variations of the course of carotid arteries is relevant for possible surgical or endovascular repair or in case of otolaryngology or intubation procedures. PMID- 27699163 TI - Fluorine-18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Findings of Post Traumatic Lymphangioma in a Young Adult Male. AB - The authors report the case of a 34-year-old male, who underwent a fluorine-18 fluoro deoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) scan 7 years after trauma for the evaluation of multifocal masses in the right iliac and right inguinal areas. CT findings showed multifocal low density masses and 18F-FDG PET revealed slightly increased uptake (maximum standardized uptake value [SUVmax] 3.1). These findings did not exclude the possibility of a benign or malignant lesion. To achieve differential diagnosis, partial surgical excision was performed and a pathologic examination subsequently revealed lymphangioma. Here, the authors describe the 18F-FDG PET/CT findings of a rare case of lymphangioma resulting from trauma. PMID- 27699165 TI - Birth Spacing of Pregnant Women in Nepal: A Community-Based Study. AB - BACKGROUND: Optimal birth spacing has health advantages for both mother and child. In developing countries, shorter birth intervals are common and associated with social, cultural, and economic factors, as well as a lack of family planning. This study investigated the first birth interval after marriage and preceding interbirth interval in Nepal. METHODS: A community-based prospective cohort study was conducted in the Kaski district of Nepal. Information on birth spacing, demographic, and obstetric characteristics was obtained from 701 pregnant women using a structured questionnaire. Logistic regression analyses were performed to ascertain factors associated with short birth spacing. RESULTS: About 39% of primiparous women gave their first child birth within 1 year of marriage and 23% of multiparous women had short preceding interbirth intervals (<24 months). The average birth spacing among the multiparous group was 44.9 (SD 21.8) months. Overall, short birth spacing appeared to be inversely associated with advancing maternal age. For the multiparous group, Janajati and lower caste women, and those whose newborn was female, were more likely to have short birth spacing. CONCLUSION: The preceding interbirth interval was relatively long in the Kaski district of Nepal and tended to be associated with maternal age, caste, and sex of newborn infant. Optimal birth spacing programs should target Janajati and lower caste women, along with promotion of gender equality in society. PMID- 27699156 TI - Diagnosis and Treatment of Lower Extremity Deep Vein Thrombosis: Korean Practice Guidelines. AB - Lower extremity deep vein thrombosis is a serious medical condition that can result in death or major disability due to pulmonary embolism or post-thrombotic syndrome. Appropriate diagnosis and treatment are required to improve symptoms and salvage the affected limb. Early thrombus clearance rapidly resolves symptoms related to venous obstruction, restores valve function and reduces the incidence of post-thrombotic syndrome. Recently, endovascular treatment has been established as a standard method for early thrombus removal. However, there are a variety of views regarding the indications and procedures among medical institutions and operators. Therefore, we intend to provide evidence-based guidelines for diagnosis and treatment of lower extremity deep vein thrombosis by multidisciplinary consensus. These guidelines are the result of a close collaboration between interventional radiologists and vascular surgeons. The goals of these guidelines are to improve treatment, to serve as a guide to the clinician, and consequently to contribute to public health care. PMID- 27699164 TI - Exploring Changes in Two Types of Self-Efficacy Following Participation in a Chronic Disease Self-Management Program. AB - Chronic conditions and falls are related issues faced by many aging adults. Stanford's Chronic Disease Self-Management Program (CDSMP) added brief fall related content to the standardized 6-week workshop; however, no research had examined changes in Fall-related self-efficacy (SE) in response to CDSMP participation. This study explored relationships and changes in SE using the SE to manage chronic disease scale (SEMCD Scale) and the Fall Efficacy Scale (FallE Scale) in participants who successfully completed CDSMP workshops within a Southern state over a 10-month period. SE scale data were compared at baseline and post-intervention for 36 adults (mean age = 74.5, SD = +/-9.64). Principal component analysis (PCA), using oblimin rotation was completed at baseline and post-intervention for the individual scales and then for analysis combining both scales as a single scale. Each scale loaded under a single component for the PCA at both baseline and post-intervention. When both scales were entered as single meta-scale, the meta-scale split along two factors with no double loading. SEMCD and FallE Scale scores were significantly correlated at baseline and post intervention, at least p < 0.05. A significant proportion of participants improved their scores on the FallE Scale post-intervention (p = 0.038). The magnitude of the change was also significant only for the FallE Scale (p = 0.043). The SEMCD Scale scores did not change significantly. Study findings from the exploratory PCA and significant correlations indicated that the SEMCD Scale and the FallE Scale measured two distinct but related types of SE. Though the scale scores were correlated at baseline and post-intervention, only the FallE Scale scores significantly differed post-intervention. Given this relationship and CDSMP's recent addition of a 10-min fall prevention segment, further exploration of CDSMP's possible influence on Fall-related SE would provide useful understanding for health promotion in aging adults. PMID- 27699166 TI - The Brief Symptom Inventory and the Outcome Questionnaire-45 in the Assessment of the Outcome Quality of Mental Health Interventions. AB - Self-report questionnaires are economical instruments for routine outcome assessment. In this study, the performance of the German version of the Outcome Questionnaire-45 (OQ-45) and the Brief Symptom Inventory (BSI) was evaluated when applied in analysis of the outcome quality of psychiatric and psychotherapeutic interventions. Pre-post data from two inpatient samples (N = 5711) and one outpatient sample (N = 239) were analyzed. Critical differences (reliable change index) and cut-off points between functional and dysfunctional populations were calculated using the Jacobson and Truax method of calculating clinical significance. Overall, the results indicated that the BSI was more accurate than the OQ-45 in correctly classifying patients as clinical subjects. Nonetheless, even with the BSI, about 25% of inpatients with schizophrenia attained a score at admission below the clinical cut-off. Both questionnaires exhibited the highest sensitivity to psychopathology with patients with personality disorders. When considering the differences in the prescores, both questionnaires showed the same sensitivity to change. The advantage of using these self-report measures is observed primarily in assessing outpatient psychotherapy outcome. In an inpatient setting two main problems-namely, the low response rate and the scarce sensitivity to psychopathology with severely ill patients-limit the usability of self-report questionnaires. PMID- 27699167 TI - Obstructive Sleep Apnea in Women: Specific Issues and Interventions. AB - Obstructive sleep apnea (OSA) has traditionally been seen as a male disease. However, the importance of OSA in women is increasingly being recognized, along with a number of significant gender-related differences in the symptoms, diagnosis, consequences, and treatment of OSA. Women tend to have less severe OSA than males, with a lower apnea-hypopnea index (AHI) and shorter apneas and hypopneas. Episodes of upper airway resistance that do not meet the criteria for apneas are more common in women. Prevalence rates are lower in women, and proportionally fewer women receive a correct diagnosis. Research has also documented sex differences in the upper airway, fat distribution, and respiratory stability in OSA. Hormones are implicated in some gender-related variations, with differences between men and women in the prevalence of OSA decreasing as age increases. The limited data available suggest that although the prevalence and severity of OSA may be lower in women than in men, the consequences of the disease are at least the same, if not worse for comparable degrees of severity. Few studies have investigated gender differences in the effects of OSA treatment. However, given the differences in physiology and presentation, it is possible that personalized therapy may provide more optimal care. PMID- 27699169 TI - Analysis of the Influence of Complexity and Entropy of Odorant on Fractal Dynamics and Entropy of EEG Signal. AB - An important challenge in brain research is to make out the relation between the features of olfactory stimuli and the electroencephalogram (EEG) signal. Yet, no one has discovered any relation between the structures of olfactory stimuli and the EEG signal. This study investigates the relation between the structures of EEG signal and the olfactory stimulus (odorant). We show that the complexity of the EEG signal is coupled with the molecular complexity of the odorant, where more structurally complex odorant causes less fractal EEG signal. Also, odorant having higher entropy causes the EEG signal to have lower approximate entropy. The method discussed here can be applied and investigated in case of patients with brain diseases as the rehabilitation purpose. PMID- 27699168 TI - The Endothelial Glycocalyx: New Diagnostic and Therapeutic Approaches in Sepsis. AB - Sepsis is defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. The endothelial glycocalyx is one of the earliest sites involved during sepsis. This fragile layer is a complex network of cell-bound proteoglycans, glycosaminoglycan side chains, and sialoproteins lining the luminal side of endothelial cells with a thickness of about 1 to 3 MUm. Sepsis-associated alterations of its structure affect endothelial permeability and result in the liberation of endogenous damage-associated molecular patterns (DAMPs). Once liberated in the circulatory system, DAMPs trigger the devastating consequences of the proinflammatory cascades in sepsis and septic shock. In this way, the injury to the glycocalyx with the consecutive release of DAMPs contributes to a number of specific clinical effects of sepsis, including acute kidney injury, respiratory failure, and septic cardiomyopathy. Moreover, the extent of glycocalyx degradation serves as a marker of endothelial dysfunction and sepsis severity. In this review, we highlight the crucial role of the glycocalyx in sepsis as a diagnostic tool and discuss the potential of members of the endothelial glycocalyx serving as hopeful therapeutic targets in sepsis associated multiple organ failures. PMID- 27699170 TI - Network Based Approach in the Establishment of the Relationship between Type 2 Diabetes Mellitus and Its Complications at the Molecular Level Coupled with Molecular Docking Mechanism. AB - Diabetes mellitus (DM) is one of the major metabolic disorders that is currently threatening the world. DM is seen associated with obesity and diabetic retinopathy (DR). In the present paper we tried to evaluate the relationship between the three aliments at the gene level and further performed the molecular docking to identify the common drug for all the three diseases. We have adopted several software programs such as Phenopedia, VennViewer, and CDOCKER to accomplish the objective. Our results revealed six genes that commonly associated and are involved in the signalling pathway. Furthermore, evaluation of common gene association from the selected set of genes projected the presence of SIRT1 in all the three aliments. Therefore, we targeted protein 4KXQ which was produced from the gene SIRT1 and challenged it with eight phytochemicals, adopting the CDOCKER. C1 compound has displayed highest -CDOCKER energy and -CDOCKER interaction energy of 43.6905 and 43.3953, respectively. Therefore, this compound is regarded as the most potential lead molecule. PMID- 27699171 TI - Effect of Dissection and Reconstruction of Palatal Muscles on Morphological Features and Ultrastructure of the Oral Musculature in Cats. AB - The study was designed to determine the effect of dissection and reconstruction of palatal muscles on muscle morphology in cats. 27 cats were randomly divided into three groups according to the extent of muscle dissection from the palatal midline. All dissections were performed from the posterior border of the hard palate, and the muscles were allowed to reconstruct over time. The morphological features were determined by hematoxylin and eosin staining of tissue sections, and ultrastructure was observed under a transmission electron microscope. As a result, no obvious differences were evident in the morphological features or ultrastructure of animals in the <1/3rd and 1/3rd-2/3rd area groups. In the >2/3rd area group, the muscles fibers were disordered and inflammatory cell infiltration and naive muscle cells were found at one month after surgery. At the second and third month after surgery, the muscle fibers showed regular alignment, the naive muscle fibers gradually matured, and the number of infiltrating inflammatory cells decreased. Muscle ultrastructure analysis revealed that myocommata were correctly aligned, and the Z line was more distinct. In conclusion, extensive dissection of palatal muscles does not result in fibrosis. Injury to oral musculature can be repaired and the musculature regenerated over time. PMID- 27699172 TI - Inhibitory Effect of Long-Chain Fatty Acids on Biogas Production and the Protective Effect of Membrane Bioreactor. AB - Anaerobic digestion of lipid-containing wastes for biogas production is often hampered by the inhibitory effect of long-chain fatty acids (LCFAs). In this study, the inhibitory effects of LCFAs (palmitic, stearic, and oleic acid) on biogas production as well as the protective effect of a membrane bioreactor (MBR) against LCFAs were examined in thermophilic batch digesters. The results showed that palmitic and oleic acid with concentrations of 3.0 and 4.5 g/L resulted in >50% inhibition on the biogas production, while stearic acid had an even stronger inhibitory effect. The encased cells in the MBR system were able to perform better in the presence of LCFAs. This system exhibited a significantly lower percentage of inhibition than the free cell system, not reaching over 50% at any LCFA concentration tested. PMID- 27699173 TI - Experimental Models of Oral Biofilms Developed on Inert Substrates: A Review of the Literature. AB - The oral ecosystem is a very complex environment where more than 700 different bacterial species can be found. Most of them are organized in biofilm on dental and mucosal surfaces. Studying this community is important because a rupture in stability can lead to the preeminence of pathogenic microorganisms, causing dental decay, gingivitis, or periodontitis. The multitude of species complicates biofilm analysis so its reproduction, collection, and counting are very delicate. The development of experimental models of dental biofilms was therefore essential and multiple in vitro designs have emerged, each of them especially adapted to observing biofilm formation of specific bacteria within specific environments. The aim of this review is to analyze oral biofilm models. PMID- 27699174 TI - Oxygen Saturation in Closed-Globe Blunt Ocular Trauma. AB - Purpose. To evaluate the oxygen saturation in retinal blood vessels in patients after closed-globe blunt ocular trauma. Design. Retrospective observational case series. Methods. Retinal oximetry was performed in both eyes of 29 patients with unilateral closed-globe blunt ocular trauma. Arterial oxygen saturation (SaO2), venous oxygen saturation (SvO2), arteriovenous difference in oxygen saturation (SO2), arteriolar diameter, venular diameter, and arteriovenous difference in diameter were measured. Association parameters including age, finger pulse oximetry, systolic pressure, diastolic pressure, and heart rate were analyzed. Results. The mean SaO2 in traumatic eyes (98.1% +/- 6.8%) was not significantly different from SaO2 in unaffected ones (95.3% +/- 7.2%) (p = 0.136). Mean SvO2 in traumatic eyes (57.1% +/- 10.6%) was significantly lower than in unaffected ones (62.3% +/- 8.4%) (p = 0.044). The arteriovenous difference in SO2 in traumatic eyes (41.0% +/- 11.2%) was significantly larger than in unaffected ones (33.0% +/ 6.9%) (p = 0.002). No significant difference was observed between traumatic eyes and unaffected ones in arteriolar (p = 0.249) and venular diameter (p = 0.972) as well as arteriovenous difference in diameter (p = 0.275). Conclusions. Oxygen consumption is increased in eyes after cgBOT, associated with lower SvO2 and enlarged arteriovenous difference in SO2 but not with changes in diameter of retinal vessels. PMID- 27699175 TI - Regulation of Hepatic Stellate Cells and Fibrogenesis by Fibroblast Growth Factors. AB - Fibroblast growth factors (FGFs) are a family of growth factors critically involved in developmental, physiological, and pathological processes, including embryogenesis, angiogenesis, wound healing, and endocrine functions. In the liver, several FGFs are produced basally by hepatocytes and hepatic stellate cells (HSCs). Upon insult to the liver, expression of FGFs in HSCs is greatly upregulated, stimulating hepatocyte regeneration and growth. Various FGF isoforms have also been shown to directly induce HSC proliferation and activation thereby enabling autocrine and paracrine regulation of HSC function. Regulation of HSCs by the endocrine FGFs, namely, FGF15/19 and FGF21, has also recently been identified. With the ability to modulate HSC proliferation and transdifferentiation, targeting FGF signaling pathways constitutes a promising new therapeutic strategy to treat hepatic fibrosis. PMID- 27699176 TI - Effects of Bufei Yishen Granules Combined with Acupoint Sticking Therapy on Pulmonary Surfactant Proteins in Chronic Obstructive Pulmonary Disease Rats. AB - Our previous studies have demonstrated the beneficial effects of Bufei Yishen granules combined with acupoint sticking therapy (the integrated therapy) in chronic obstructive pulmonary disease (COPD), but the underlying mechanism remains unclear. Dysfunction of pulmonary surfactant proteins (SPs, including SP A, SP-B, SP-C, and SP-D) may be included in pathophysiology of COPD. This study aimed to explore the mechanism of the integrated therapy on SPs. COPD rat models were established. The treatment groups received Bufei Yishen granules or acupoint sticking or their combination. Using aminophylline as a positive control drug. The levels of SPs in serum, BALF, and lung were measured. The results showed that the integrated therapy markedly reduced the levels of SPs in serum and increased these indicators in the lung. The integrated therapy was better than aminophylline in reducing the levels of SPs and was better than Bufei Yishen granules in reducing SP-A, SP-C, and SP-D in serum. The integrated therapy was better than aminophylline and Bufei Yishen granules in increasing SP-A, SP-B, and SP-D mRNA in the lung. SP-A and SP-D in BALF were positively correlated with PEF and EF50. The levels of SPs are associated with airway limitation. The beneficial effects of the integrated therapy may be involved in regulating pulmonary surfactant proteins. PMID- 27699177 TI - A Facile Approach for the Mass Production of Submicro/Micro Poly (Lactic Acid) Fibrous Mats and Their Cytotoxicity Test towards Neural Stem Cells. AB - Despite many of the studies being conducted, the electrospinning of poly (lactic acid) (PLA), dissolved in its common solvents, is difficult to be continuously processed for mass production. This is due to the polymer solution droplet drying. Besides, the poor stretching capability of the polymer solution limits the production of small diameter fibers. To address these issues, we have examined the two following objectives: first, using an appropriate solvent system for the mass production of fibrous mats with fine-tunable fiber diameters; second, nontoxicity of the mats towards Neural Stem Cell (NSC). To this aim, TFA (trifluoroacetic acid) was used as a cosolvent, in a mixture with DCM (dichloromethane), and the solution viscosity, surface tension, electrical conductivity, and the continuity of the electrospinning process were compared with the solutions prepared with common single solvents. The binary solvent facilitated PLA electrospinning, resulting in a long lasting, stable electrospinning condition, due to the low surface tension and high conductivity of the binary-solvent system. The fiber diameter was tailored from nano to micro by varying effective parameters and examined by scanning electron microscopy (SEM) and image-processing software. Laminin-coated electrospun mats supported NSC expansion and spreading, as examined using AlamarBlue assay and fluorescent microscopy, respectively. PMID- 27699179 TI - Effects of a Patient-Provider, Collaborative, Medication-Planning Tool: A Randomized, Controlled Trial. AB - Among patients with various levels of health literacy, the effects of collaborative, patient-provider, medication-planning tools on outcomes relevant to self-management are uncertain. Objective. Among adult patients with type II diabetes mellitus, we tested the effectiveness of a medication-planning tool (MedtableTM) implemented via an electronic medical record to improve patients' medication knowledge, adherence, and glycemic control compared to usual care. Design. A multicenter, randomized controlled trial in outpatient primary care clinics. 674 patients received either the Medtable tool or usual care and were followed up for up to 12 months. Results. Patients who received Medtable had greater knowledge about indications for medications in their regimens and were more satisfied with the information about their medications. Patients' knowledge of drug indication improved with Medtable regardless of their literacy status. However, Medtable did not improve patients' demonstrated medication use, regimen adherence, or glycemic control (HbA1c). Conclusion. The Medtable tool supported provider/patient collaboration related to medication use, as reflected in patient satisfaction with communication, but had limited impact on patient medication knowledge, adherence, and HbA1c outcomes. This trial is registered with ClinicalTrials.gov NCT01296633. PMID- 27699178 TI - Molecular Diagnostics for Precision Medicine in Colorectal Cancer: Current Status and Future Perspective. AB - Precision medicine, a concept that has recently emerged and has been widely discussed, emphasizes tailoring medical care to individuals largely based on information acquired from molecular diagnostic testing. As a vital aspect of precision cancer medicine, targeted therapy has been proven to be efficacious and less toxic for cancer treatment. Colorectal cancer (CRC) is one of the most common cancers and among the leading causes for cancer related deaths in the United States and worldwide. By far, CRC has been one of the most successful examples in the field of precision cancer medicine, applying molecular tests to guide targeted therapy. In this review, we summarize the current guidelines for anti-EGFR therapy, revisit the roles of pathologists in an era of precision cancer medicine, demonstrate the transition from traditional "one test-one drug" assays to multiplex assays, especially by using next-generation sequencing platforms in the clinical diagnostic laboratories, and discuss the future perspectives of tumor heterogeneity associated with anti-EGFR resistance and immune checkpoint blockage therapy in CRC. PMID- 27699180 TI - Altered Macrophage and Dendritic Cell Response in Mif-/- Mice Reveals a Role of Mif for Inflammatory-Th1 Response in Type 1 Diabetes. AB - Macrophage migration inhibitory factor (Mif) is highly expressed in type 1 diabetes mellitus (T1DM). However, there is limited information about how Mif influences the activation of macrophages (Mphi) and dendritic cells (DC) in T1DM. To address this issue, we induced T1DM by administering multiple low doses of streptozotocin (STZ) to Mif-/- or wild-type (Wt) BALB/c mice. We found that Mif-/ mice treated with STZ (Mif-/-STZ) developed lower levels of hyperglycemia, inflammatory cytokines, and specific pancreatic islet antigen- (PIAg-) IgG and displayed reduced cellular infiltration into the pancreatic islets compared to Wt mice treated with STZ (WtSTZ). Moreover, Mphi and DC from Mif-/-STZ displayed lower expression of MHC-II, costimulatory molecules CD80, CD86, and CD40, Toll like receptor- (TLR-) 2, and TLR-4 than WtSTZ. These changes were associated with a reduced capacity of Mphi and DC from Mif-/-STZ to induce proliferation in ovalbumin-specific T cells. All the deficiencies observed in Mif-/-STZ were recovered by exogenous administration of recombinant Mif. These findings suggest that Mif plays a role in the molecular mechanisms of Mphi and DC activation and drives T cell responses involved in the pathology of T1DM. Therefore, Mif is a potential therapeutic target to reduce the pathology of T1DM. PMID- 27699183 TI - Gram-Positive Diplococci in a Cerebrospinal Fluid Gram Stain. PMID- 27699181 TI - Characteristics of HLA-E Restricted T-Cell Responses and Their Role in Infectious Diseases. AB - Human HLA-E can, in addition to self-antigens, also present pathogen-derived sequences, which elicit specific T-cell responses. T-cells recognize their antigen presented by HLA-E highly specifically and have unique functional and phenotypical properties. Pathogen specific HLA-E restricted CD8+ T-cells are an interesting new player in the field of immunology. Future work should address their exact roles and relative contributions in the immune response against infectious diseases. PMID- 27699184 TI - Family Intervention for Obese/Overweight Children Using Portion Control Strategy (FOCUS) for Weight Control: A Randomized Controlled Trial. AB - Nutritional counseling for children with obesity is an important component of management. This randomized controlled trial was conducted to compare change in body mass index (BMI) z score after 6 months. Children 8 to 16 years with a BMI greater than the 85th percentile were randomized to standard of care nutrition counseling versus intervention with standard nutrition counseling including portion control tool training for the family. Measures were completed at baseline, 3 months, and 6 months. Fifty-one children were randomized to control and 48 to intervention. Mean age was 11 years (SD = 2.2). Mean BMI z score was 2.7 (SD = 0.4). Forty-five percent were male (n = 45). Follow-up at 6 months was 73.7% (73/99). Although no differences were seen between the groups, there was a significant decrease in BMI z score between baseline and 6 months within each group. PMID- 27699185 TI - Dataset of red light induced pupil constriction superimposed on post-illumination pupil response. AB - We collected and analyzed pupil diameter data from of 7 visually normal participants to compare the maximum pupil constriction (MPC) induced by "Red Only" vs. "Blue+Red" visual stimulation conditions. The "Red Only" condition consisted of red light (640+/-10 nm) stimuli of variable intensity and duration presented to dark-adapted eyes with pupils at resting state. This condition stimulates the cone-driven activity of the intrinsically photosensitive retinal ganglion cells (ipRGC). The "Blue+Red" condition consisted of the same red light stimulus presented during ongoing blue (470+/-17 nm) light-induced post illumination pupil response (PIPR), representing the cone-driven ipRGC activity superimposed on the melanopsin-driven intrinsic activity of the ipRGCs ("The Absence of Attenuating Effect of Red light Exposure on Pre-existing Melanopsin Driven Post-illumination Pupil Response" Lei et al. (2016) [1]). MPC induced by the "Red Only" condition was compared with the MPC induced by the "Blue+Red" condition by multiple paired sample t-tests with Bonferroni correction. PMID- 27699182 TI - Study of Soluble HLA-G in Congenital Human Cytomegalovirus Infection. AB - Human leukocyte antigen-G (HLA-G) is a nonclassical HLA class I antigen that is expressed during pregnancy contributing to maternal-fetal tolerance. HLA-G can be expressed as membrane-bound and soluble forms. HLA-G expression increases strongly during viral infections such as congenital human cytomegalovirus (HCMV) infections, with functional consequences in immunoregulation. In this work we investigated the expression of soluble (s)HLA-G and beta-2 microglobulin (component of HLA) molecules in correlation with the risk of transmission and severity of congenital HCMV infection. We analyzed 182 blood samples from 130 pregnant women and 52 nonpregnant women and 56 amniotic fluid samples from women experiencing primary HCMV infection. The median levels of sHLA-G in maternal serum of women with primary HCMV infection were higher in comparison with nonprimary and uninfected pregnant women (p < 0.001). AF from HCMV symptomatic fetuses presented higher sHLA-G levels in comparison with infected asymptomatic fetuses (p < 0.001), presence of HLA-G free-heavy chain, and a concentration gradient from amniotic fluid to maternal blood. No significant statistical difference of beta-2 microglobulin median levels was observed between all different groups. Our results suggest the determination of sHLA-G molecules in both maternal blood and amniotic fluid as a promising biomarker of diagnosis of maternal HCMV primary infection and fetal HCMV disease.

AB - Using purified reaction components, a commercial monoclonal antibody (Ab) specific to RNase inhibitor (RI) was found to interfere with the activity of RI. Total RNA was mixed with a monoclonal Ab specific to either RI (clone 3F11) or glyceraldehyde-3-phosphate dehydrogenase (GAPDH), RNase A, RI, or a combination of the above. Following incubation for 1 h at 22 degrees C or 37 degrees C, RNA integrity of the mixtures was assessed using microfluidics-based Bio-Rad Experion RNA electrophoresis. The addition of Ab 3F11 prevented RI from effectively inhibiting RNase A and therefore resulted in extensive RNA degradation.

PMID- 27699192 TI - Data describing inhibitory profiles of sugars against hemagglutination by the botulinum toxin complex of Clostridium botulinum serotypes C and D. AB - Serotype C and D of Clostridium botulinum produce botulinum toxin complex (TC), which is comprised of botulinum neurotoxin, nontoxic nonhemagglutinin, and hemagglutinins (HAs). The TC is capable of aggregating equine erythrocytes via interaction between one of the HAs, namely HA-33, and sugar chains on the cell surface. This hemagglutination is inhibited by specific sugars. In this data article, we used four TCs from serotype C and D strains. The hemagglutination inhibiting effects of 18 sugars and 8 glycoproteins were studied. The purified TC was mixed with the sugar to enable binding of the sugar to the TC; then, the erythrocytes were added to the mixture. Specific binding between the sugar and TC resulted in inhibition of cell aggregation. Here, data illustrating the inhibitory effects of various sugars and glycoproteins against hemagglutination induced by TC of C. botulinum serotypes C and D are presented.

We further show under which circumstances various oxidation products of RSV such as ROS can be produced. For example, in addition to the widely known effect of bicarbonate ions, high pH values promote the decay of RSV. Moreover, we analyse the impact of reduction of the oxygen partial pressure on the pH-dependent oxidation of RSV.

PMID- 27699198 TI - Morbility, clinical data and proteomic analysis of IUGR and AGA newborns at different gestational ages. AB - The data are related to the proteomic analysis of 43 newborns with intrauterine growth retardation (IUGR) and 45 newborns with appropriate weight for gestational age (AGA) carried out by separation via 2DE and analyzed by MS-TOF/TOF. All newborns were separated into three gestational age groups, "Very Preterm" 29-32 weeks, "Moderate Preterm" 33-36 weeks, and, "Term" >=37weeks. From each newborn, blood was drawn three times from birth to 1 month life. High-abundant serum proteins were depleted, and the minority ones were separated by 2DE and analyzed for significant expression differences. The data reflect analytic and clinic variables analyzed globally and categorized by gestational age in relation to IUGR and the optimization of conditions for 2-DE separation. The data from this study are related to the research article entitled "Alterations of Protein Expression in Serum of Infants with Intrauterine Growth Restriction and Different Gestational Ages" (M.D. Ruis-Gonzalez, M.D. Canete, J.L. Gomez-Chaparro, N. Abril, R. Canete, J. Lopez-Barea, 2015) [1]. The present dataset of serum IUGR newborn proteome can be used as a reference for any study involving intrauterine growth restriction during the first month of life.

AB - OBJECTIVES: The introduction of prenatal cfDNA screening for fetal aneuploidy and other genetic conditions has exacerbated concerns about informed decision-making in clinical prenatal testing. To assess the information provided to patients to facilitate decisions about cfDNA screening, we collected written patient education and consent documents created by laboratories and clinics. METHODS: Informed consent documents (IC) were coded by two independent coders. Each IC was assessed for readability, attention to elements of informed consent, and completeness of information about the test and the screened conditions. RESULTS: We found variance between IC produced by commercial laboratories versus those provided by local clinics or health care systems, and considerable variance among materials from all sources. "Commercial" IC were longer and written at a more difficult reading level than "non-commercial" IC, and were less likely to state explicitly that cfDNA only screens for certain conditions. About one-third of IC were combined with laboratory order forms. Though most IC recommended confirmatory testing for positive results, only about half clearly stated that results could be incorrect-including mentions of false positives or false negatives. About one-third of IC explicitly stated that cfDNA screening was optional. While nearly all IC from any source listed the conditions screened by the test, only about half of the IC included any phenotypic descriptions of these conditions. Few IC mentioned psychosocial considerations, and only one IC mentioned the availability of support groups for families of children with genetic conditions. CONCLUSIONS: Based on our findings, we recommend that written and well-informed consent be sought before performing cfDNA screening, and we offer minimal and recommended standards for patient education and consent materials. PMID- 27699201 TI - Restoration Effects of the Riparian Forest on the Intertidal Fish Fauna in an Urban Area of the Amazon River. AB - Urbanization causes environmental impacts that threaten the health of aquatic communities and alter their recovery patterns. In this study, we evaluated the diversity of intertidal fish in six areas affected by urbanization (areas with native vegetation, deforested areas, and areas in process of restoration of vegetation) along an urban waterfront in the Amazon River. 20 species were identified, representing 17 genera, 14 families, and 8 orders. The different degrees of habitat degradation had a major effect on the composition of the fish fauna; the two least affected sectors were the only ones in that all 20 species were found. Eight species were recorded in the most degraded areas. The analysis revealed two well-defined groups, coinciding with the sectors in better ecological quality and degraded areas, respectively. The native vegetation has been identified as the crucial factor to the recovery and homeostasis of the studied ecosystem, justifying its legal protection and its use in the restoration and conservation of altered and threatened environments. These results reinforce the importance of maintaining the native vegetation as well as its restoration in order to benefit of the fish populations in intertidal zones impacted by alterations resulting from inadequate urbanization. PMID- 27699202 TI - Low-Carbon Watershed Management: Potential of Greenhouse Gas Reductions from Wastewater Treatment in Rural Vietnam. AB - Currently in many cities and rural areas of Vietnam, wastewater is discharged to the environment without any treatment, which emits considerable amount of greenhouse gas (GHG), particularly methane. In this study, four GHG emission scenarios were examined, as well as the baseline scenario, in order to verify the potential of GHG reduction from domestic wastewater with adequate treatment facilities. The ArcGIS and ArcHydro tools were employed to visualize and analyze GHG emissions resulting from discharge of untreated wastewater, in rural areas of Vu Gia Thu Bon river basin, Vietnam. By applying the current IPCC guidelines for GHG emissions, we found that a reduction of GHG emissions can be achieved through treatment of domestic wastewater in the studied area. Compared with baseline scenario, a maximum 16% of total GHG emissions can be reduced, in which 30% of households existing latrines are substituted by Japanese Johkasou technology and other 20% of domestic wastewater is treated by conventional activated sludge. PMID- 27699203 TI - Control of Pedicle Screw Placement with an Electrical Conductivity Measurement Device: Initial Evaluation in the Thoracic and Lumbar Spine. AB - Aim. Transpedicular screw fixation is widely used in spinal surgery. But the insertion of pedicle screws can sometimes be challenging because of the variability in pedicle size and the proximity of nerve roots. Methods. We detected intraoperatively the sensitivity for iatrogenic pedicel perforation with a hand-held electronic conductivity measurement device (ECD) that measures electrical conductivity of tissue-medium surrounding the instrument tip. ECD was used to guide the placement of 84 pedicle screws in 15 patients undergoing surgery for tumor or degenerative spinal disease at various spinal levels from T8 to L5. Additionally a CT-scan controlled screw positioning postoperatively. Results. The placement was "correct" (no mediocaudal pedicle wall penetration) for 78 of 84 (92,8%) screws, "suboptimal but acceptable" (0-2 mm penetration) for 4 of 84 (4,8%) screws, and "misplaced" (penetration > 2 mm) for 2 of 84 (2,4%) screws. Conclusion. Although this study was not designed to compare electronic conductivity technique to other guidance methods, such as fluoroscopy or navigation, a convincing "proof of concept" for ECD use in spinal instrumentation could be demonstrated. Advantages include easy handling without time-consuming setup and reduced X-ray exposure. However, further investigations are necessary to evaluate i.a. the economic aspects for this single-use developed instrument. PMID- 27699204 TI - Role of Ultrasound in Body Stalk Anomaly and Amniotic Band Syndrome. AB - Body stalk anomaly (BSA) and amniotic band syndrome (ABS) are rare similar fetal sporadic polymalformative syndromes of unknown etiology, though there are certain differences between them. BSA is a combination of developmental abnormalities involving neural tube, body wall, and the limbs with persistent extra embryonic coelomic cavity. ABS is characterized by the presence of thin membrane-like strands attached to fetal body parts and causing constrictions and amputations. This is a cohort study involving 32,100 patients who were referred for routine antenatal ultrasound scan. The data was entered prospectively into a computer database. The duration of study was 3 years. In our study, ultrasound examination in 86 patients demonstrated ventral wall defects, craniofacial defects, and spinal and limb deformities as isolated or combined abnormalities. In those, 10 patients were suspected/diagnosed as BSA/ABS including a twin of a dichorionic diamniotic gestation. The typical features of body stalk anomaly can be detected by ultrasound by the end of the first trimester, which is important for the patient counselling and management. We are presenting these rare conditions and highlighting the importance of early sonographic imaging in diagnosing and differentiating them from other anterior abdominal wall defects. PMID- 27699205 TI - Seroprevalence of Canine Parvovirus in Dogs in Lusaka District, Zambia. AB - Canine parvovirus (CPV) enteritis is a highly contagious enteric disease of young dogs. Limited studies have been done in Zambia to investigate the prevalence of CPV in dogs. Blood was collected from dogs from three veterinary clinics (clinic samples, n = 174) and one township of Lusaka (field samples, n = 56). Each dog's age, sex, breed, and vaccination status were recorded. A haemagglutination assay using pig erythrocytes and modified live parvovirus vaccine as the antigen was used. Antibodies to CPV were detected in 100% of dogs (unvaccinated or vaccinated). The titres ranged from 160 to 10240 with a median of 1280. Vaccinated dogs had significantly higher antibody titres compared to unvaccinated (p < 0.001). There was a significant difference in titres of clinic samples compared to field samples (p < 0.0001) but not within breed (p = 0.098) or sex (p = 0.572). Multiple regression analysis showed that only age and vaccination status were significant predictors of antibody titres. The presence of antibody in all dogs suggests that the CPV infection is ubiquitous and the disease is endemic, hence the need for research to determine the protection conferred by vaccination and natural exposure to the virus under local conditions. PMID- 27699207 TI - Slow Cholinergic Modulation of Spike Probability in Ultra-Fast Time-Coding Sensory Neurons. AB - Sensory processing in the lower auditory pathway is generally considered to be rigid and thus less subject to modulation than central processing. However, in addition to the powerful bottom-up excitation by auditory nerve fibers, the ventral cochlear nucleus also receives efferent cholinergic innervation from both auditory and nonauditory top-down sources. We thus tested the influence of cholinergic modulation on highly precise time-coding neurons in the cochlear nucleus of the Mongolian gerbil. By combining electrophysiological recordings with pharmacological application in vitro and in vivo, we found 55-72% of spherical bushy cells (SBCs) to be depolarized by carbachol on two time scales, ranging from hundreds of milliseconds to minutes. These effects were mediated by nicotinic and muscarinic acetylcholine receptors, respectively. Pharmacological block of muscarinic receptors hyperpolarized the resting membrane potential, suggesting a novel mechanism of setting the resting membrane potential for SBC. The cholinergic depolarization led to an increase of spike probability in SBCs without compromising the temporal precision of the SBC output in vitro. In vivo, iontophoretic application of carbachol resulted in an increase in spontaneous SBC activity. The inclusion of cholinergic modulation in an SBC model predicted an expansion of the dynamic range of sound responses and increased temporal acuity. Our results thus suggest of a top-down modulatory system mediated by acetylcholine which influences temporally precise information processing in the lower auditory pathway. PMID- 27699206 TI - Smooth versus Textured Surfaces: Feature-Based Category Selectivity in Human Visual Cortex. AB - In fMRI studies, human lateral occipital (LO) cortex is thought to respond selectively to images of objects, compared with nonobjects. However, it remains unresolved whether all objects evoke equivalent levels of activity in LO, and, if not, which image features produce stronger activation. Here, we used an unbiased parametric texture model to predict preferred versus nonpreferred stimuli in LO. Observation and psychophysical results showed that predicted preferred stimuli (both objects and nonobjects) had smooth (rather than textured) surfaces. These predictions were confirmed using fMRI, for objects and nonobjects. Similar preferences were also found in the fusiform face area (FFA). Consistent with this: (1) FFA and LO responded more strongly to nonfreckled (smooth) faces, compared with otherwise identical freckled (textured) faces; and (2) strong functional connections were found between LO and FFA. Thus, LO and FFA may be part of an information-processing stream distinguished by feature-based category selectivity (smooth > textured). PMID- 27699208 TI - The Temporal Dynamics of Scene Processing: A Multifaceted EEG Investigation. AB - Our remarkable ability to process complex visual scenes is supported by a network of scene-selective cortical regions. Despite growing knowledge about the scene representation in these regions, much less is known about the temporal dynamics with which these representations emerge. We conducted two experiments aimed at identifying and characterizing the earliest markers of scene-specific processing. In the first experiment, human participants viewed images of scenes, faces, and everyday objects while event-related potentials (ERPs) were recorded. We found that the first ERP component to evince a significantly stronger response to scenes than the other categories was the P2, peaking ~220 ms after stimulus onset. To establish that the P2 component reflects scene-specific processing, in the second experiment, we recorded ERPs while the participants viewed diverse real-world scenes spanning the following three global scene properties: spatial expanse (open/closed), relative distance (near/far), and naturalness (man made/natural). We found that P2 amplitude was sensitive to these scene properties at both the categorical level, distinguishing between open and closed natural scenes, as well as at the single-image level, reflecting both computationally derived scene statistics and behavioral ratings of naturalness and spatial expanse. Together, these results establish the P2 as an ERP marker for scene processing, and demonstrate that scene-specific global information is available in the neural response as early as 220 ms. PMID- 27699210 TI - Orientation Tuning Depends on Spatial Frequency in Mouse Visual Cortex. AB - The response properties of neurons to sensory stimuli have been used to identify their receptive fields and to functionally map sensory systems. In primary visual cortex, most neurons are selective to a particular orientation and spatial frequency of the visual stimulus. Using two-photon calcium imaging of neuronal populations from the primary visual cortex of mice, we have characterized the response properties of neurons to various orientations and spatial frequencies. Surprisingly, we found that the orientation selectivity of neurons actually depends on the spatial frequency of the stimulus. This dependence can be easily explained if one assumed spatially asymmetric Gabor-type receptive fields. We propose that receptive fields of neurons in layer 2/3 of visual cortex are indeed spatially asymmetric, and that this asymmetry could be used effectively by the visual system to encode natural scenes. PMID- 27699209 TI - Loss of Ikbkap Causes Slow, Progressive Retinal Degeneration in a Mouse Model of Familial Dysautonomia. AB - Familial dysautonomia (FD) is an autosomal recessive congenital neuropathy that is caused by a mutation in the gene for inhibitor of kappa B kinase complex associated protein (IKBKAP). Although FD patients suffer from multiple neuropathies, a major debilitation that affects their quality of life is progressive blindness. To determine the requirement for Ikbkap in the developing and adult retina, we generated Ikbkap conditional knockout (CKO) mice using a TUBA1a promoter-Cre (Talpha1-Cre). In the retina, Talpha1-Cre expression is detected predominantly in retinal ganglion cells (RGCs). At 6 months, significant loss of RGCs had occurred in the CKO retinas, with the greatest loss in the temporal retina, which is the same spatial phenotype observed in FD, Leber hereditary optic neuropathy, and dominant optic atrophy. Interestingly, the melanopsin-positive RGCs were resistant to degeneration. By 9 months, signs of photoreceptor degeneration were observed, which later progressed to panretinal degeneration, including RGC and photoreceptor loss, optic nerve thinning, Muller glial activation, and disruption of layers. Taking these results together, we conclude that although Ikbkap is not required for normal development of RGCs, its loss causes a slow, progressive RGC degeneration most severely in the temporal retina, which is later followed by indirect photoreceptor loss and complete retinal disorganization. This mouse model of FD is not only useful for identifying the mechanisms mediating retinal degeneration, but also provides a model system in which to attempt to test therapeutics that may mitigate the loss of vision in FD patients. PMID- 27699211 TI - Altered Spatiotemporal Dynamics of Cortical Activation to Tactile Stimuli in Somatosensory Area 3b and Area 1 of Monkeys after Spinal Cord Injury. AB - Reactivation of deafferented cortex plays a key role in mediating the recovery of lost functions, although the precise mechanism is not fully understood. This study simultaneously characterized the dynamic spatiotemporal features of tactile responses in areas 3b and 1 before and 6-8 weeks after partial dorsal column lesion (DCL), and examined how the reactivation relates to the recovery of simple hand use in squirrel monkeys. A combination of high spatiotemporal resolution functional intrinsic optical imaging, microelectrode mapping, behavioral assessment, and tracer histology methods were used. Compared with the normal cortex, we found that the responses of deafferented areas 3b and 1 to 3 s of continuous 8 Hz tactile stimulation of a single digit were significantly weaker and more transient. This finding indicates a loss of response to sustained tactile stimuli. The activation area enlarged for areas 3b and 1 in both directions along digit representation (medial-lateral) and across areas (anterior posterior). All subjects showed behavioral deficits in a food reaching-grasping retrieving task within the first 5 weeks after DCL, but recovered at the time when optical images were acquired. Summarily, we showed that these populations of cortical neurons responded to peripheral tactile inputs, albeit in significantly altered manners in each area, several weeks after deafferentation. We propose that compromised ascending driven inputs, impaired lateral inhibition, and local integration of input signals may account for the altered spatiotemporal dynamics of the reactivated areas 3b and 1 cortices. Further investigation with large sample sizes is needed to fully characterize the effects of deafferentation on area 1 activation size. PMID- 27699212 TI - Reduced Vglut2/Slc17a6 Gene Expression Levels throughout the Mouse Subthalamic Nucleus Cause Cell Loss and Structural Disorganization Followed by Increased Motor Activity and Decreased Sugar Consumption. AB - The subthalamic nucleus (STN) plays a central role in motor, cognitive, and affective behavior. Deep brain stimulation (DBS) of the STN is the most common surgical intervention for advanced Parkinson's disease (PD), and STN has lately gained attention as target for DBS in neuropsychiatric disorders, including obsessive compulsive disorder, eating disorders, and addiction. Animal studies using STN-DBS, lesioning, or inactivation of STN neurons have been used extensively alongside clinical studies to unravel the structural organization, circuitry, and function of the STN. Recent studies in rodent STN models have exposed different roles for STN neurons in reward-related functions. We have previously shown that the majority of STN neurons express the vesicular glutamate transporter 2 gene (Vglut2/Slc17a6) and that reduction of Vglut2 mRNA levels within the STN of mice [conditional knockout (cKO)] causes reduced postsynaptic activity and behavioral hyperlocomotion. The cKO mice showed less interest in fatty rewards, which motivated analysis of reward-response. The current results demonstrate decreased sugar consumption and strong rearing behavior, whereas biochemical analyses show altered dopaminergic and peptidergic activity in the striatum. The behavioral alterations were in fact correlated with opposite effects in the dorsal versus the ventral striatum. Significant cell loss and disorganization of the STN structure was identified, which likely accounts for the observed alterations. Rare genetic variants of the human VGLUT2 gene exist, and this study shows that reduced Vglut2/Slc17a6 gene expression levels exclusively within the STN of mice is sufficient to cause strong modifications in both the STN and the mesostriatal dopamine system. PMID- 27699215 TI - Our inaugural issue. AB - We are delighted to publish the first set of articles in JCI Insight, the newest peer-reviewed publication of the American Society for Clinical Investigation (ASCI), a nonprofit honor society for physician-scientists. In creating this journal, we sought to provide an expanded forum for a wide range of preclinical, translational, and clinical research that uncovers new insights into the basis of disease and therapeutic approaches. In selecting articles for JCI Insight, we place a strong emphasis on rigorous experimental methods and data reporting, which are truly the hallmark of publications in the JCI family. Like the research in the Journal of Clinical Investigation, all articles in JCI Insight are freely available from the moment of publication. ASCI is proud to continue this tradition of open access, which we believe to be a cornerstone of the dissemination of scientific findings.

AB - Renal tubular atrophy and interstitial fibrosis are common hallmarks of etiologically different progressive chronic kidney diseases (CKD) that eventually result in organ failure. Even though these pathological manifestations constitute a major public health problem, diagnostic tests, as well as therapeutic options, are currently limited. Members of the dickkopf (DKK) family, DKK1 and -2, have been associated with inhibition of Wnt signaling and organ fibrosis. Here, we identify DKK3 as a stress-induced, tubular epithelia-derived, secreted glycoprotein that mediates kidney fibrosis. Genetic as well as antibody-mediated abrogation of DKK3 led to reduced tubular atrophy and decreased interstitial matrix accumulation in two mouse models of renal fibrosis. This was facilitated by an amplified, antifibrogenic, inflammatory T cell response and diminished canonical Wnt/beta-catenin signaling in stressed tubular epithelial cells. Moreover, in humans, urinary DKK3 levels specifically correlated with the extent of tubular atrophy and interstitial fibrosis in different glomerular and tubulointerstitial diseases. In summary, our data suggest that DKK3 constitutes an immunosuppressive and a profibrotic epithelial protein that might serve as a potential therapeutic target and diagnostic marker in renal fibrosis. PMID- 27699216 TI - Deep sequencing reveals microRNAs predictive of antiangiogenic drug response. AB - The majority of metastatic renal cell carcinoma (RCC) patients are treated with tyrosine kinase inhibitors (TKI) in first-line treatment; however, a fraction are refractory to these antiangiogenic drugs. MicroRNAs (miRNAs) are regulatory molecules proven to be accurate biomarkers in cancer. Here, we identified miRNAs predictive of progressive disease under TKI treatment through deep sequencing of 74 metastatic clear cell RCC cases uniformly treated with these drugs. Twenty nine miRNAs were differentially expressed in the tumors of patients who progressed under TKI therapy (P values from 6 * 10-9 to 3 * 10-3). Among 6 miRNAs selected for validation in an independent series, the most relevant associations corresponded to miR-1307-3p, miR-155-5p, and miR-221-3p (P = 4.6 * 10-3, 6.5 * 10 3, and 3.4 * 10-2, respectively). Furthermore, a 2 miRNA-based classifier discriminated individuals with progressive disease upon TKI treatment (AUC = 0.75, 95% CI, 0.64-0.85; P = 1.3 * 10-4) with better predictive value than clinicopathological risk factors commonly used. We also identified miRNAs significantly associated with progression-free survival and overall survival (P = 6.8 * 10-8 and 7.8 * 10-7 for top hits, respectively), and 7 overlapped with early progressive disease. In conclusion, this is the first miRNome comprehensive study, to our knowledge, that demonstrates a predictive value of miRNAs for TKI response and provides a new set of relevant markers that can help rationalize metastatic RCC treatment. PMID- 27699214 TI - Relationships among injury, fibrosis, and time in human kidney transplants. AB - BACKGROUND: Kidney transplant biopsies offer an opportunity to understand the pathogenesis of organ fibrosis. We studied the relationships between the time of biopsy after transplant (TxBx), histologic fibrosis, diseases, and transcript expression. METHODS: Expression microarrays from 681 kidney transplant indication biopsies taken either early (n = 282, <1 year) or late (n = 399, >1 year) after transplant were used to analyze the molecular landscape of fibrosis in relationship to histologic fibrosis and diseases. RESULTS: Fibrosis was absent at transplantation but was present in some early biopsies by 4 months after transplant, apparently as a self-limited response to donation implantation injury not associated with progression to failure. The molecular phenotype of early biopsies represented the time sequence of the response to wounding: immediate expression of acute kidney injury transcripts, followed by fibrillar collagen transcripts after several weeks, then by the appearance of immunoglobulin and mast cell transcripts after several months as fibrosis appeared. Fibrosis in late biopsies correlated with injury, fibrillar collagen, immunoglobulin, and mast cell transcripts, but these were independent of time. Pathway analysis revealed epithelial response-to-wounding pathways such as Wnt/beta-catenin. CONCLUSION: Fibrosis in late biopsies had different associations because many kidneys had potentially progressive diseases and subsequently failed. Molecular correlations with fibrosis in late biopsies were independent of time, probably because ongoing injury obscured the response-to-wounding time sequence. The results indicate that fibrosis in kidney transplants is driven by nephron injury and that progression to failure reflects continuing injury, not autonomous fibrogenesis.

PMID- 27699217 TI - Perinatal tolerance to proinsulin is sufficient to prevent autoimmune diabetes. AB - High-affinity self-reactive thymocytes are purged in the thymus, and residual self-reactive T cells, which are detectable in healthy subjects, are controlled by peripheral tolerance mechanisms. Breakdown in these mechanisms results in autoimmune disease, but antigen-specific therapy to augment natural mechanisms can prevent this. We aimed to determine when antigen-specific therapy is most effective. Islet autoantigens, proinsulin (PI), and islet-specific glucose-6 phosphatase catalytic subunit-related protein (IGRP) were expressed in the antigen-presenting cells (APCs) of autoimmune diabetes-prone nonobese diabetic (NOD) mice in a temporally controlled manner. PI expression from gestation until weaning was sufficient to completely protect NOD mice from diabetes, insulitis, and development of insulin autoantibodies. Insulin-specific T cells were significantly diminished, were naive, and did not express IFN-gamma when challenged. This long-lasting effect from a brief period of treatment suggests that autoreactive T cells are not produced subsequently. We tracked IGRP206-214 specific CD8+ T cells in NOD mice expressing IGRP in APCs. When IGRP was expressed only until weaning, IGRP206-214-specific CD8+ T cells were not detected later in life. Thus, anti-islet autoimmunity is determined during early life, and autoreactive T cells are not generated in later life. Bolstering tolerance to islet antigens in the perinatal period is sufficient to impart lasting protection from diabetes. PMID- 27699218 TI - The MEK inhibitor trametinib separates murine graft-versus-host disease from graft-versus-tumor effects. AB - The efficacy of allogeneic hematopoietic stem cell transplantation for hematologic malignancies is limited by the difficulty in suppressing graft-versus host disease (GVHD) without compromising graft-versus-tumor (GVT) effects. We previously showed that RAS/MEK/ERK signaling depends on memory differentiation in human T cells, which confers susceptibility to selective inhibition of naive T cells. Actually, antineoplastic MEK inhibitors selectively suppress alloreactive T cells, sparing virus-specific T cells in vitro. Here, we show that trametinib, a MEK inhibitor clinically approved for melanoma, suppresses GVHD safely without affecting GVT effects in vivo. Trametinib prolonged survival of GVHD mice and attenuated GVHD symptoms and pathology in the gut and skin. It inhibited ERK1/2 phosphorylation and expansion of donor T cells, sparing Tregs and B cells. Although high-dose trametinib inhibited myeloid cell engraftment, low-dose trametinib suppressed GVHD without severe adverse events. Notably, trametinib facilitated the survival of mice transplanted with allogeneic T cells and P815 tumor cells with no residual P815 cells observed in the livers and spleens, whereas tacrolimus resulted in P815 expansion. These results confirm that trametinib selectively suppresses GVHD-inducing T cells while sparing antitumor T cells in vivo, which makes it a promising candidate for translational studies aimed at preventing or treating GVHD. PMID- 27699220 TI - Biofilm in group A streptococcal necrotizing soft tissue infections. AB - Necrotizing fasciitis caused by group A streptococcus (GAS) is a life threatening, rapidly progressing infection. At present, biofilm is not recognized as a potential problem in GAS necrotizing soft tissue infections (NSTI), as it is typically linked to chronic infections or associated with foreign devices. Here, we present a case of a previously healthy male presenting with NSTI caused by GAS. The infection persisted over 24 days, and the surgeon documented the presence of a "thick layer biofilm" in the fascia. Subsequent analysis of NSTI patient tissue biopsies prospectively included in a multicenter study revealed multiple areas of biofilm in 32% of the patients studied. Biopsies associated with biofilm formation were characterized by massive bacterial load, a pronounced inflammatory response, and clinical signs of more severe tissue involvement. In vitro infections of a human skin tissue model with GAS NSTI isolates also revealed multilayered fibrous biofilm structures, which were found to be under the control of the global Nra gene regulator. The finding of GAS biofilm formation in NSTIs emphasizes the urgent need for biofilm to be considered as a potential complicating microbiological feature of GAS NSTI and, consequently, emphasizes reconsideration of antibiotic treatment protocols. PMID- 27699219 TI - Profiling cancer testis antigens in non-small-cell lung cancer. AB - Cancer testis antigens (CTAs) are of clinical interest as biomarkers and present valuable targets for immunotherapy. To comprehensively characterize the CTA landscape of non-small-cell lung cancer (NSCLC), we compared RNAseq data from 199 NSCLC tissues to the normal transcriptome of 142 samples from 32 different normal organs. Of 232 CTAs currently annotated in the Caner Testis Database (CTdatabase), 96 were confirmed in NSCLC. To obtain an unbiased CTA profile of NSCLC, we applied stringent criteria on our RNAseq data set and defined 90 genes as CTAs, of which 55 genes were not annotated in the CTdatabase, thus representing potential new CTAs. Cluster analysis revealed that CTA expression is histology dependent and concurrent expression is common. IHC confirmed tissue specific protein expression of selected new CTAs (TKTL1, TGIF2LX, VCX, and CXORF67). Furthermore, methylation was identified as a regulatory mechanism of CTA expression based on independent data from The Cancer Genome Atlas. The proposed prognostic impact of CTAs in lung cancer was not confirmed, neither in our RNAseq cohort nor in an independent meta-analysis of 1,117 NSCLC cases. In summary, we defined a set of 90 reliable CTAs, including information on protein expression, methylation, and survival association. The detailed RNAseq catalog can guide biomarker studies and efforts to identify targets for immunotherapeutic strategies. PMID- 27699221 TI - Soluble membrane attack complex is diagnostic for intraventricular shunt infection in children. AB - BACKGROUND: Children treated with cerebrospinal fluid (CSF) shunts to manage hydrocephalus frequently develop shunt failure and/or infections, conditions that present with overlapping symptoms. The potential life-threatening nature of shunt infections requires rapid diagnosis; however, traditional microbiology is time consuming, expensive, and potentially unreliable. We set out to identify a biomarker that would identify shunt infection. METHODS: CSF was assayed for the soluble membrane attack complex (sMAC) by ELISA in patients with suspected shunt failure or infection. CSF was obtained at the time of initial surgical intervention. Statistical analysis was performed to assess the diagnostic potential of sMAC in pyogenic-infected versus noninfected patients. RESULTS: Children with pyogenic shunt infection had significantly increased sMAC levels compared with noninfected patients (3,211 +/- 1,111 ng/ml vs. 26 +/- 3.8 ng/ml, P = 0.0001). In infected patients undergoing serial CSF draws, sMAC levels were prognostic for both positive and negative clinical outcomes. Children with delayed, broth-only growth of commensal organisms (P. acnes, S. epidermidis, etc.) had the lowest sMAC levels (7.96 +/- 1.7 ng/ml), suggesting contamination rather than shunt infection. CONCLUSION: Elevated CSF sMAC levels are both sensitive and specific for diagnosing pyogenic shunt infection and may serve as a useful prognostic biomarker during recovery from infection.

AB - Over one-fifth of North American women of childbearing age are obese, putting these women at risk for a variety of detrimental chronic diseases. In addition, obesity increases the risk for developing major complications during pregnancy. The mechanisms by which obesity contributes to pregnancy complications and loss remain unknown. Increasing evidence indicates that obesity results in major changes to adipose tissue immune cell composition and function; whether or not obesity also affects immune function in the uterus has not been explored. Here we investigated the effect of obesity on uterine natural killer (uNK) cells, which are essential for uterine artery remodeling and placental development. Using a cohort of obese or lean women, we found that obesity led to a significant reduction in uNK cell numbers accompanied with impaired uterine artery remodeling. uNK cells isolated from obese women had altered expression of genes and pathways associated with extracellular matrix remodeling and growth factor signaling. Specifically, uNK cells were hyper-responsive to PDGF, resulting in overexpression of decorin. Functionally, decorin strongly inhibited placental development by limiting trophoblast survival. Together, these findings establish a potentially new link between obesity and poor pregnancy outcomes, and indicate that obesity-driven changes to uterine-resident immune cells critically impair placental development. PMID- 27699223 TI - Heterogeneous fibroblasts underlie age-dependent tertiary lymphoid tissues in the kidney. AB - Acute kidney injury (AKI) is a common clinical condition defined as a rapid decline in kidney function. AKI is a global health burden, estimated to cause 2 million deaths annually worldwide. Unlike AKI in the young, which is reversible, AKI in the elderly often leads to end-stage renal disease, and the mechanism that prevents kidney repair in the elderly is unclear. Here we demonstrate that aged but not young mice developed multiple tertiary lymphoid tissues (TLTs) in the kidney after AKI. TLT size was associated with impaired renal function and increased expression of proinflammatory cytokines and homeostatic chemokines, indicating a possible contribution of TLTs to sustained inflammation after injury. Notably, resident fibroblasts from a single lineage diversified into p75 neurotrophin receptor+ (p75NTR+) fibroblasts and homeostatic chemokine-producing fibroblasts inside TLTs, and retinoic acid-producing fibroblasts around TLTs. Deletion of CD4+ cells as well as late administration of dexamethasone abolished TLTs and improved renal outcomes. Importantly, aged but not young human kidneys also formed TLTs that had cellular and molecular components similar to those of mouse TLTs. Therefore, the inhibition of TLT formation may offer a novel therapeutic strategy for AKI in the elderly. PMID- 27699224 TI - Systemic restoration of UBA1 ameliorates disease in spinal muscular atrophy. AB - The autosomal recessive neuromuscular disease spinal muscular atrophy (SMA) is caused by loss of survival motor neuron (SMN) protein. Molecular pathways that are disrupted downstream of SMN therefore represent potentially attractive therapeutic targets for SMA. Here, we demonstrate that therapeutic targeting of ubiquitin pathways disrupted as a consequence of SMN depletion, by increasing levels of one key ubiquitination enzyme (ubiquitin-like modifier activating enzyme 1 [UBA1]), represents a viable approach for treating SMA. Loss of UBA1 was a conserved response across mouse and zebrafish models of SMA as well as in patient induced pluripotent stem cell-derive motor neurons. Restoration of UBA1 was sufficient to rescue motor axon pathology and restore motor performance in SMA zebrafish. Adeno-associated virus serotype 9-UBA1 (AAV9-UBA1) gene therapy delivered systemic increases in UBA1 protein levels that were well tolerated over a prolonged period in healthy control mice. Systemic restoration of UBA1 in SMA mice ameliorated weight loss, increased survival and motor performance, and improved neuromuscular and organ pathology. AAV9-UBA1 therapy was also sufficient to reverse the widespread molecular perturbations in ubiquitin homeostasis that occur during SMA. We conclude that UBA1 represents a safe and effective therapeutic target for the treatment of both neuromuscular and systemic aspects of SMA. PMID- 27699225 TI - Identification of microRNA-181a-5p and microRNA-4454 as mediators of facet cartilage degeneration. AB - Osteoarthritis (OA) of spine (facet joints [FJs]) is one of the major causes of severe low back pain and disability worldwide. The degeneration of facet cartilage is a hallmark of FJ OA. However, endogenous mechanisms that initiate degeneration of facet cartilage are unknown, and there are no disease-modifying therapies to stop FJ OA. In this study, we have identified microRNAs (small noncoding RNAs) as mediators of FJ cartilage degeneration. We first established a cohort of patients with varying degrees of facet cartilage degeneration (control group: normal or mild facet cartilage degeneration; FJ OA group: moderate to severe facet cartilage degeneration) and then screened 2,100 miRNAs and identified 2 miRNAs (miR-181a-5p and miR-4454) that were significantly elevated in FJ OA cartilage compared with control facet cartilage. We further explored their role, function, and signaling mechanisms using computational, in vitro functional, and in vivo studies. We specifically indicate that miR-181a-5p and miR-4454 are involved in promoting inflammatory, catabolic, and cell death activity in FJ chondrocytes. This is the first report to our knowledge that identifies miR-181a-5p and miR-4454 as mediators of cartilage degeneration in FJs and potential therapeutic targets for stopping cartilage degeneration. PMID- 27699226 TI - Aldehyde dehydrogenase inhibition blocks mucosal fibrosis in human and mouse ocular scarring. AB - Mucous membrane pemphigoid (MMP) is a systemic mucosal scarring disease, commonly causing blindness, for which there is no antifibrotic therapy. Aldehyde dehydrogenase family 1 (ALDH1) is upregulated in both ocular MMP (OMMP) conjunctiva and cultured fibroblasts. Application of the ALDH metabolite, retinoic acid (RA), to normal human conjunctival fibroblasts in vitro induced a diseased phenotype. Conversely, application of ALDH inhibitors, including disulfiram, to OMMP fibroblasts in vitro restored their functionality to that of normal controls. ALDH1 is also upregulated in the mucosa of the mouse model of scarring allergic eye disease (AED), used here as a surrogate for OMMP, in which topical application of disulfiram decreased fibrosis in vivo. These data suggest that progressive scarring in OMMP results from ALDH/RA fibroblast autoregulation, that the ALDH1 subfamily has a central role in immune-mediated ocular mucosal scarring, and that ALDH inhibition with disulfiram is a potential and readily translatable antifibrotic therapy. PMID- 27699227 TI - Elimination of p19ARF-expressing cells enhances pulmonary function in mice. AB - Senescent cells accumulate in many tissues as animals age and are considered to underlie several aging-associated pathologies. The tumor suppressors p19ARF and p16INK4a, both of which are encoded in the CDKN2A locus, play critical roles in inducing and maintaining permanent cell cycle arrest during cellular senescence. Although the elimination of p16INK4a-expressing cells extends the life span of the mouse, it is unclear whether tissue function is restored by the elimination of senescent cells in aged animals and whether and how p19ARF contributes to tissue aging. The aging-associated decline in lung function is characterized by an increase in compliance as well as pathogenic susceptibility to pulmonary diseases. We herein demonstrated that pulmonary function in 12-month-old mice was reversibly restored by the elimination of p19ARF-expressing cells. The ablation of p19ARF-expressing cells using a toxin receptor-mediated cell knockout system ameliorated aging-associated lung hypofunction. Furthermore, the aging-associated gene expression profile was reversed after the elimination of p19ARF. Our results indicate that the aging-associated decline in lung function was, at least partly, attributed to p19ARF and was recovered by eliminating p19ARF-expressing cells. PMID- 27699228 TI - Decreases in thymopoiesis of astronauts returning from space flight. AB - Following the advent of molecular assays that measure T cell receptor excision circles (TRECs) present in recent thymic emigrants, it has been conclusively shown that thymopoiesis persists in most adults, but that functional output decreases with age, influencing the maintenance of a diverse and functional T cell receptor (TCR) repertoire. Space flight has been shown to result in a variety of phenotypic and functional changes in human T cells and in the reactivation of latent viruses. While space flight has been shown to influence thymic architecture in rodents, thymopoiesis has not previously been assessed in astronauts. Here, we assessed thymopoiesis longitudinally over a 1-year period prior to and after long-term space flight (median duration, 184 days) in 16 astronauts. While preflight assessments of thymopoiesis remained quite stable in individual astronauts, we detected significant suppression of thymopoiesis in all subjects upon return from space flight. We also found significant increases in urine and plasma levels of endogenous glucocorticoids coincident with the suppression of thymopoiesis. The glucocorticoid induction and thymopoiesis suppression were transient, and they normalized shortly after return to Earth. This is the first report to our knowledge to prospectively demonstrate a significant change in thymopoiesis in healthy individuals in association with a defined physiologic emotional and physical stress event. These results suggest that suppression of thymopoiesis has the potential to influence the maintenance of the TCR repertoire during extended space travel. Further studies of thymopoiesis and endogenous glucocorticoids in other stress states, including illness, are warranted. PMID- 27699229 TI - Quantum coherence spectroscopy to measure dietary fat retention in the liver. AB - The prevalence of fatty liver reaches alarming proportions. Fatty liver increases the risk for insulin resistance, cardiovascular disease, and nonalcoholic steatohepatitis (NASH). Although extensively studied in a preclinical setting, the lack of noninvasive methodologies hampers our understanding of which pathways promote hepatic fat accumulation in humans. Dietary fat retention is one of the pathways that may lead to fatty liver. The low (1.1%) natural abundance (NA) of carbon-13 (13C) allows use of 13C-enriched lipids for in vivo MR studies. Successful implementation of such methodology, however, is challenging due to low sensitivity of 13C-magnetic resonance spectroscopy (13C-MRS). Here, we investigated the use of 1-dimensional gradient enhanced heteronuclear single quantum coherence (ge-HSQC) spectroscopy for the in vivo detection of hepatic 1H [13C]-lipid signals after a single high-fat meal with 13C-labeled fatty acids in 5 lean and 6 obese subjects. Postprandial retention of orally administered 13C labeled fatty acids was significant (P < 0.01). Approximately 1.5% of the tracer was retained in the liver after 6 hours, and retention was similar in both groups (P = 0.92). Thus, a substantial part of the liver fat can originate directly from storage of meal-derived fat. The ge-HSQC can be used to noninvasively reveal the contribution of dietary fat to the development of hepatic steatosis over time. PMID- 27699230 TI - A cord blood monocyte-derived cell therapy product accelerates brain remyelination. AB - Microglia and monocytes play important roles in regulating brain remyelination. We developed DUOC-01, a cell therapy product intended for treatment of demyelinating diseases, from banked human umbilical cord blood (CB) mononuclear cells. Immunodepletion and selection studies demonstrated that DUOC-01 cells are derived from CB CD14+ monocytes. We compared the ability of freshly isolated CB CD14+ monocytes and DUOC-01 cells to accelerate remyelination of the brains of NOD/SCID/IL2Rgammanull mice following cuprizone feeding-mediated demyelination. The corpus callosum of mice intracranially injected with DUOC-01 showed enhanced myelination, a higher proportion of fully myelinated axons, decreased gliosis and cellular infiltration, and more proliferating oligodendrocyte lineage cells than those of mice receiving excipient. Uncultured CB CD14+ monocytes also accelerated remyelination, but to a significantly lesser extent than DUOC-01 cells. Microarray analysis, quantitative PCR studies, Western blotting, and flow cytometry demonstrated that expression of factors that promote remyelination including PDGF-AA, stem cell factor, IGF1, MMP9, MMP12, and triggering receptor expressed on myeloid cells 2 were upregulated in DUOC-01 compared to CB CD14+ monocytes. Collectively, our results show that DUOC-01 accelerates brain remyelination by multiple mechanisms and could be beneficial in treating demyelinating conditions. PMID- 27699231 TI - Gene pathway development in human epicardial adipose tissue during early life. AB - Studies in rodents and newborn humans demonstrate the influence of brown adipose tissue (BAT) in temperature control and energy balance and a critical role in the regulation of body weight. Here, we obtained samples of epicardial adipose tissue (EAT) from neonates, infants, and children in order to evaluate changes in their transcriptional landscape by applying a systems biology approach. Surprisingly, these analyses revealed that the transition to infancy is a critical stage for changes in the morphology of EAT and is reflected in unique gene expression patterns of a substantial proportion of thermogenic gene transcripts (~10%). Our results also indicated that the pattern of gene expression represents a distinct developmental stage, even after the rebound in abundance of thermogenic genes in later childhood. Using weighted gene coexpression network analyses, we found precise anthropometric-specific correlations with changes in gene expression and the decline of thermogenic capacity within EAT. In addition, these results indicate a sequential order of transcriptional events affecting cellular pathways, which could potentially explain the variation in the amount, or activity, of BAT in adulthood. Together, these results provide a resource to elucidate gene regulatory mechanisms underlying the progressive development of BAT during early life. PMID- 27699233 TI - T cell responses to human platelet antigen-1a involve a unique form of indirect allorecognition. AB - Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a pregnancy-related condition caused by maternal antibodies binding an alloantigen on fetal platelets. In most cases the alloantigen is formed by a single amino acid, integrin beta3 Leu33, referred to as human platelet antigen-1a (HPA-1a). Production of anti-HPA-1a antibodies likely depends on CD4+ T cells that recognize the same alloantigen in complex with the HLA-DRA/DRB3*01:01 molecule. While this complex is well characterized, T cell recognition of it is not. Here, to examine the nature of antigen recognition by HPA-1a-specific T cells, we assayed native and synthetic variants of the integrin beta3 peptide antigen for binding to DRA/DRB3*01:01-positive antigen-presenting cells and for T cell activation. We found that HPA-1a-specific T cells recognize non-allogeneic integrin beta3 residues anchored to DRA/DRB3*01:01 by the allogeneic Leu33, which itself is not directly recognized by these T cells. Furthermore, these T cell responses are diverse, with different T cells depending on different residues for recognition. This represents a unique form of indirect allorecognition in which a non-allogeneic peptide sequence becomes immunogenic by stable anchoring to MHC by an allogeneic residue. PMID- 27699232 TI - The antifibrotic drug pirfenidone promotes pulmonary cavitation and drug resistance in a mouse model of chronic tuberculosis. AB - Pirfenidone is a recently approved antifibrotic drug for the treatment of idiopathic pulmonary fibrosis (IPF). Because tuberculosis (TB) is characterized by granulomatous inflammation in conjunction with parenchymal destruction and replacement fibrosis, we sought to determine whether the addition of pirfenidone as an adjunctive, host-directed therapy provides a beneficial effect during antimicrobial treatment of TB. We hypothesized that pirfenidone's antiinflammatory and antifibrotic properties would reduce inflammatory lung damage and increase antimicrobial drug penetration in granulomas to accelerate treatment response. The effectiveness of adjunctive pirfenidone during TB drug therapy was evaluated using a murine model of chronic TB. Mice treated with standard therapy 2HRZ/4HR (H, isoniazid; R, rifampin; and Z, pyrazinamide) were compared with 2 alternative regimens containing pirfenidone (Pf) (2HRZPf/4HRPf and 2HRZPf/4HR). Contrary to our hypothesis, adjunctive pirfenidone use leads to reduced bacterial clearance and increased relapse rates. This treatment failure is closely associated with the emergence of isoniazid monoresistant bacilli, increased cavitation, and significant lung pathology. While antifibrotic agents may eventually be used as part of adjunctive host-directed therapy of TB, this study clearly demonstrates that caution must be exercised. Moreover, as pirfenidone becomes more widely used in clinical practice, increased patient monitoring would be required in endemic TB settings. PMID- 27699234 TI - Telomere dysfunction in alveolar epithelial cells causes lung remodeling and fibrosis. AB - Telomeres are short in type II alveolar epithelial cells (AECs) of patients with idiopathic pulmonary fibrosis (IPF). Whether dysfunctional telomeres contribute directly to development of lung fibrosis remains unknown. The objective of this study was to investigate whether telomere dysfunction in type II AECs, mediated by deletion of the telomere shelterin protein TRF1, leads to pulmonary fibrosis in mice (SPC-Cre TRF1fl/fl mice). Deletion of TRF1 in type II AECs for 2 weeks increased gammaH2AX DNA damage foci, but not histopathologic changes in the lung. Deletion of TRF1 in type II AECs for up to 9 months resulted in short telomeres and lung remodeling characterized by increased numbers of type II AECs, alpha smooth muscle actin+ mesenchymal cells, collagen deposition, and accumulation of senescence-associated beta-galactosidase+ lung epithelial cells. Deletion of TRF1 in collagen-expressing cells caused pulmonary edema, but not fibrosis. These results demonstrate that prolonged telomere dysfunction in type II AECs, but not collagen-expressing cells, leads to age-dependent lung remodeling and fibrosis. We conclude that telomere dysfunction in type II AECs is sufficient to cause lung fibrosis, and may be a dominant molecular defect causing IPF. SPC-Cre TRF1fl/fl mice will be useful for assessing cellular and molecular mechanisms of lung fibrosis mediated by telomere dysfunction. PMID- 27699235 TI - IL1RL1 asthma risk variants regulate airway type 2 inflammation. AB - Genome-wide association studies of asthma have identified genetic variants in the IL1RL1 gene, but the molecular mechanisms conferring risk are unknown. IL1RL1 encodes the ST2 receptor (ST2L) for IL-33 and an inhibitory decoy receptor (sST2). IL-33 promotes type 2 inflammation, which is present in some but not all asthmatics. We find that two single nucleotide polymorphisms (SNPs) in IL1RL1 - rs1420101 and rs11685480 - are strongly associated with plasma sST2 levels, though neither is an expression quantitative trait locus (eQTL) in whole blood. Rather, rs1420101 and rs11685480 mark eQTLs in airway epithelial cells and distal lung parenchyma, respectively. We find that the genetically determined plasma sST2 reservoir, derived from the lung, neutralizes IL-33 activity, and these eQTL SNPs additively increase the risk of airway type 2 inflammation among asthmatics. These risk variants define a population of asthmatics at risk of IL-33-driven type 2 inflammation. PMID- 27699236 TI - Glymphatic fluid transport controls paravascular clearance of AAV vectors from the brain. AB - Adeno-associated viruses (AAV) are currently being evaluated in clinical trials for gene therapy of CNS disorders. However, host factors that influence the spread, clearance, and transduction efficiency of AAV vectors in the brain are not well understood. Recent studies have demonstrated that fluid flow mediated by aquaporin-4 (AQP4) channels located on astroglial end feet is essential for exchange of solutes between interstitial and cerebrospinal fluid. This phenomenon, which is essential for interstitial clearance of solutes from the CNS, has been termed glial-associated lymphatic transport or glymphatic transport. In the current study, we demonstrate that glymphatic transport profoundly affects various aspects of AAV gene transfer in the CNS. Altered localization of AQP4 in aged mouse brains correlated with significantly increased retention of AAV vectors in the parenchyma and reduced systemic leakage following ventricular administration. We observed a similar increase in AAV retention and transgene expression upon i.c.v. administration in AQP4-/- mice. Consistent with this observation, fluorophore-labeled AAV vectors showed markedly reduced flux from the ventricles of AQP4-/- mice compared with WT mice. These results were further corroborated by reduced AAV clearance from the AQP4-null brain, as demonstrated by reduced transgene expression and vector genome accumulation in systemic organs. We postulate that deregulation of glymphatic transport in aged and diseased brains could markedly affect the parenchymal spread, clearance, and gene transfer efficiency of AAV vectors. Assessment of biomarkers that report the kinetics of CSF flux in prospective gene therapy patients might inform variable treatment outcomes and guide future clinical trial design. PMID- 27699237 TI - Platelet integrin alpha6beta1 controls lung metastasis through direct binding to cancer cell-derived ADAM9. AB - Metastatic dissemination of cancer cells, which accounts for 90% of cancer mortality, is the ultimate hallmark of malignancy. Growing evidence suggests that blood platelets have a predominant role in tumor metastasis; however, the molecular mechanisms involved remain elusive. Here, we demonstrate that genetic deficiency of integrin alpha6beta1 on platelets markedly decreases experimental and spontaneous lung metastasis. In vitro and in vivo assays reveal that human and mouse platelet alpha6beta1 supports platelet adhesion to various types of cancer cells. Using a knockdown approach, we identified ADAM9 as the major counter receptor of alpha6beta1 on both human and mouse tumor cells. Static and flow-based adhesion assays of platelets binding to DC-9, a recombinant protein covering the disintegrin-cysteine domain of ADAM9, demonstrated that this receptor directly binds to platelet alpha6beta1. In vivo studies showed that the interplay between platelet alpha6beta1 and tumor cell-expressed ADAM9 promotes efficient lung metastasis. The integrin alpha6beta1-dependent platelet-tumor cell interaction induces platelet activation and favors the extravasation process of tumor cells. Finally, we demonstrate that a pharmacological approach targeting alpha6beta1 efficiently impairs tumor metastasis through a platelet-dependent mechanism. Our study reveals a mechanism by which platelets promote tumor metastasis and suggests that integrin alpha6beta1 represents a promising target for antimetastatic therapies. PMID- 27699238 TI - CFTR gene transfer with AAV improves early cystic fibrosis pig phenotypes. AB - The physiological components that contribute to cystic fibrosis (CF) lung disease are steadily being elucidated. Gene therapy could potentially correct these defects. CFTR-null pigs provide a relevant model to test gene therapy vectors. Using an in vivo selection strategy that amplifies successful capsids by replicating their genomes with helper adenovirus coinfection, we selected an adeno-associated virus (AAV) with tropism for pig airway epithelia. The evolved capsid, termed AAV2H22, is based on AAV2 with 5 point mutations that result in a 240-fold increased infection efficiency. In contrast to AAV2, AAV2H22 binds specifically to pig airway epithelia and is less reliant on heparan sulfate for transduction. We administer AAV2H22-CFTR expressing the CF transmembrane conductance regulator (CFTR) cDNA to the airways of CF pigs. The transduced airways expressed CFTR on ciliated and nonciliated cells, induced anion transport, and improved the airway surface liquid pH and bacterial killing. Most gene therapy studies to date focus solely on Cl- transport as the primary metric of phenotypic correction. Here, we describe a gene therapy experiment where we not only correct defective anion transport, but also restore bacterial killing in CFTR-null pig airways. PMID- 27699239 TI - Multiparametric profiling of non-small-cell lung cancers reveals distinct immunophenotypes. AB - BACKGROUND. Immune checkpoint blockade improves survival in a subset of patients with non-small-cell lung cancer (NSCLC), but robust biomarkers that predict response to PD-1 pathway inhibitors are lacking. Furthermore, our understanding of the diversity of the NSCLC tumor immune microenvironment remains limited. METHODS. We performed comprehensive flow cytometric immunoprofiling on both tumor and immune cells from 51 NSCLCs and integrated this analysis with clinical and histopathologic characteristics, next-generation sequencing, mRNA expression, and PD-L1 immunohistochemistry (IHC). RESULTS. Cytometric profiling identified an immunologically "hot" cluster with abundant CD8+ T cells expressing high levels of PD-1 and TIM-3 and an immunologically "cold" cluster with lower relative abundance of CD8+ T cells and expression of inhibitory markers. The "hot" cluster was highly enriched for expression of genes associated with T cell trafficking and cytotoxic function and high PD-L1 expression by IHC. There was no correlation between immunophenotype and KRAS or EGFR mutation, or patient smoking history, but we did observe an enrichment of squamous subtype and tumors with higher mutation burden in the "hot" cluster. Additionally, approximately 20% of cases had high B cell infiltrates with a subset producing IL-10. CONCLUSIONS. Our results support the use of immune-based metrics to study response and resistance to immunotherapy in lung cancer. FUNDING. The Robert A. and Renee E.

PMID- 27699240 TI - Diphtheria toxin-mediated ablation of lymphatic endothelial cells results in progressive lymphedema. AB - Development of novel treatments for lymphedema has been limited by the fact that the pathophysiology of this disease is poorly understood. It remains unknown, for example, why limb swelling resulting from surgical injury resolves initially, but recurs in some cases months or years later. Finding answers for these basic questions has been hampered by the lack of adequate animal models. In the current study, we used Cre-lox mice that expressed the human diphtheria toxin receptor (DTR) driven by a lymphatic-specific promoter in order to noninvasively ablate the lymphatic system of the hind limb. Animals treated in this manner developed lymphedema that was indistinguishable from clinical lymphedema temporally, radiographically, and histologically. Using this model and clinical biopsy specimens, we show that the initial resolution of edema after injury is dependent on the formation of collateral capillary lymphatics and that this process is regulated by M2-polarized macrophages. In addition, we show that despite these initial improvements in lymphatic function, persistent accumulation of CD4+ cells inhibits lymphangiogenesis and promotes sclerosis of collecting lymphatics, resulting in late onset of edema and fibrosis. Our findings therefore provide strong evidence that inflammatory changes after lymphatic injury play a key role in the pathophysiology of lymphedema. PMID- 27699242 TI - Flow-metabolism dissociation in the pathogenesis of levodopa-induced dyskinesia. AB - Levodopa-induced dyskinesia (LID) is the most common, disruptive complication of Parkinson's disease (PD) pharmacotherapy, yet despite decades of research, the changes in regional brain function underlying LID remain largely unknown. We previously found that the cerebral vasomotor and metabolic responses to levodopa are dissociated in PD subjects. Nonetheless, it is unclear whether levodopa mediated dissociation is exaggerated in LID or distinguishes LID from non-LID subjects. To explore this possibility, we used dual-tracer positron emission tomography to quantify regional cerebral blood flow and metabolic activity in 28 PD subjects (14 LID, 14 non-LID), scanned before and during intravenous levodopa infusion. Levodopa-mediated dissociation was most prominent in the posterior putamen (P < 0.0001) and greater in LID than in non-LID and test-retest subjects. Strikingly, LID subjects also showed increased sensorimotor cortex (SMC) activity in the baseline, unmedicated state. Imaging data from an independent PD sample (106 subjects) linked these differences to loss of mesocortical dopamine terminals in advanced patients. In aggregate, the data suggest that LID results from an overactive vasomotor response to levodopa in the putamen on a background of disease-related increases in SMC activity. LID may thus be amenable to treatment that modulates the function of these 2 regions. PMID- 27699241 TI - Adjuvanted multi-epitope vaccines protect HLA-A*11:01 transgenic mice against Toxoplasma gondii. AB - We created and tested multi-epitope DNA or protein vaccines with TLR4 ligand emulsion adjuvant (gluco glucopyranosyl lipid adjuvant in a stable emulsion [GLA SE]) for their ability to protect against Toxoplasma gondii in HLA transgenic mice. Our constructs each included 5 of our best down-selected CD8+ T cell eliciting epitopes, a universal CD4+ helper T lymphocyte epitope (PADRE), and a secretory signal, all arranged for optimal MHC-I presentation. Their capacity to elicit immune and protective responses was studied using immunization of HLA A*11:01 transgenic mice. These multi-epitope vaccines increased memory CD8+ T cells that produced IFN-gamma and protected mice against parasite burden when challenged with T. gondii. Endocytosis of emulsion-trapped protein and cross presentation of the antigens must account for the immunogenicity of our adjuvanted protein. Thus, our work creates an adjuvanted platform assembly of peptides resulting in cross presentation of CD8+ T cell-eliciting epitopes in a vaccine that prevents toxoplasmosis. PMID- 27699243 TI - Autophagy-dependent regulatory T cells are critical for the control of graft versus-host disease. AB - Regulatory T cells (Tregs) play a crucial role in the maintenance of peripheral tolerance. Quantitative and/or qualitative defects in Tregs result in diseases such as autoimmunity, allergy, malignancy, and graft-versus-host disease (GVHD), a serious complication of allogeneic stem cell transplantation (SCT). We recently reported increased expression of autophagy-related genes (Atg) in association with enhanced survival of Tregs after SCT. Autophagy is a self-degradative process for cytosolic components that promotes cell homeostasis and survival. Here, we demonstrate that the disruption of autophagy within FoxP3+ Tregs (B6.Atg7fl/fl-FoxP3cre+ ) resulted in a profound loss of Tregs, particularly within the bone marrow (BM). This resulted in dysregulated effector T cell activation and expansion, and the development of enterocolitis and scleroderma in aged mice. We show that the BM compartment is highly enriched in TIGIT+ Tregs and that this subset is differentially depleted in the absence of autophagy. Moreover, following allogeneic SCT, recipients of grafts from B6.Atg7fl/fl FoxP3cre+ donors exhibited reduced Treg reconstitution, exacerbated GVHD, and reduced survival compared with recipients of B6.WT-FoxP3cre+ grafts. Collectively, these data indicate that autophagy-dependent Tregs are critical for the maintenance of tolerance after SCT and that the promotion of autophagy represents an attractive immune-restorative therapeutic strategy after allogeneic SCT. PMID- 27699245 TI - A ferret model of COPD-related chronic bronchitis. AB - Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the US. The majority of COPD patients have symptoms of chronic bronchitis, which lacks specific therapies. A major impediment to therapeutic development has been the absence of animal models that recapitulate key clinical and pathologic features of human disease. Ferrets are well suited for the investigation of the significance of respiratory diseases, given prior data indicating similarities to human airway physiology and submucosal gland distribution. Here, we exposed ferrets to chronic cigarette smoke and found them to approximate complex clinical features of human COPD. Unlike mice, which develop solely emphysema, smoke exposed ferrets exhibited markedly higher numbers of early-morning spontaneous coughs and sporadic infectious exacerbations as well as a higher level of airway obstruction accompanied by goblet cell metaplasia/hyperplasia and increased mucus expression in small airways, indicative of chronic bronchitis and bronchiolitis. Overall, we demonstrate the first COPD animal model exhibiting clinical and pathologic features of chronic bronchitis to our knowledge, providing a key advance that will greatly facilitate the preclinical development of novel treatments for this disease. PMID- 27699244 TI - Tissue-specific metabolic reprogramming drives nutrient flux in diabetic complications. AB - Diabetes is associated with altered cellular metabolism, but how altered metabolism contributes to the development of diabetic complications is unknown. We used the BKS db/db diabetic mouse model to investigate changes in carbohydrate and lipid metabolism in kidney cortex, peripheral nerve, and retina. A systems approach using transcriptomics, metabolomics, and metabolic flux analysis identified tissue-specific differences, with increased glucose and fatty acid metabolism in the kidney, a moderate increase in the retina, and a decrease in the nerve. In the kidney, increased metabolism was associated with enhanced protein acetylation and mitochondrial dysfunction. To confirm these findings in human disease, we analyzed diabetic kidney transcriptomic data and urinary metabolites from a cohort of Southwestern American Indians. The urinary findings were replicated in 2 independent patient cohorts, the Finnish Diabetic Nephropathy and the Family Investigation of Nephropathy and Diabetes studies. Increased concentrations of TCA cycle metabolites in urine, but not in plasma, predicted progression of diabetic kidney disease, and there was an enrichment of pathways involved in glycolysis and fatty acid and amino acid metabolism. Our findings highlight tissue-specific changes in metabolism in complication-prone tissues in diabetes and suggest that urinary TCA cycle intermediates are potential prognostic biomarkers of diabetic kidney disease progression. PMID- 27699246 TI - MUTYH promotes oxidative microglial activation and inherited retinal degeneration. AB - Oxidative stress is implicated in various neurodegenerative disorders, including retinitis pigmentosa (RP), an inherited disease that causes blindness. The biological and cellular mechanisms by which oxidative stress mediates neuronal cell death are largely unknown. In a mouse model of RP (rd10 mice), we show that oxidative DNA damage activates microglia through MutY homolog-mediated (MUYTH mediated) base excision repair (BER), thereby exacerbating retinal inflammation and degeneration. In the early stage of retinal degeneration, oxidative DNA damage accumulated in the microglia and caused single-strand breaks (SSBs) and poly(ADP-ribose) polymerase activation. In contrast, Mutyh deficiency in rd10 mice prevented SSB formation in microglia, which in turn suppressed microglial activation and photoreceptor cell death. Moreover, Mutyh-deficient primary microglial cells attenuated the polarization to the inflammatory and cytotoxic phenotype under oxidative stress. Thus, MUTYH-mediated BER in oxidative microglial activation may be a novel target to dampen the disease progression in RP and other neurodegenerative disorders that are associated with oxidative stress. PMID- 27699247 TI - PKA regulatory subunit 1A inactivating mutation induces serotonin signaling in primary pigmented nodular adrenal disease. AB - Primary pigmented nodular adrenocortical disease (PPNAD) is a rare cause of ACTH independent hypercortisolism. The disease is primarily caused by germline mutations of the protein kinase A (PKA) regulatory subunit 1A (PRKAR1A) gene, which induces constitutive activation of PKA in adrenocortical cells. Hypercortisolism is thought to result from PKA hyperactivity, but PPNAD tissues exhibit features of neuroendocrine differentiation, which may lead to stimulation of steroidogenesis by abnormally expressed neurotransmitters. We hypothesized that serotonin (5-HT) may participate in the pathophysiology of PPNAD-associated hypercortisolism. We show that PPNAD tissues overexpress the 5-HT synthesizing enzyme tryptophan hydroxylase type 2 (Tph2) and the serotonin receptors types 4, 6, and 7, leading to formation of an illicit stimulatory serotonergic loop whose pharmacological inhibition in vitro decreases cortisol production. In the human PPNAD cell line CAR47, the PKA inhibitor H-89 decreases 5-HT4 and 5-HT7 receptor expression. Moreover, in the human adrenocortical cell line H295R, inhibition of PRKAR1A expression increases the expression of Tph2 and 5-HT4/6/7 receptors, an effect that is blocked by H-89. These findings show that the serotonergic process observed in PPNAD tissues results from PKA activation by PRKAR1A mutations. They also suggest that Tph inhibitors may represent efficient treatments of hypercortisolism in patients with PPNAD. PMID- 27699248 TI - Bladder catheterization increases susceptibility to infection that can be prevented by prophylactic antibiotic treatment. AB - Catheter-associated urinary tract infections (CAUTI) are the most common hospital associated infections. Here, we report that bladder catheterization initiated a persistent sterile inflammatory reaction within minutes of catheter implantation. Catheterization resulted in increased expression of genes associated with defense responses and cellular migration, with ensuing rapid and sustained innate immune cell infiltration into the bladder. Catheterization also resulted in hypersensitivity to Enterococcus faecalis and uropathogenic Escherichia coli (UPEC) infection, in which colonization was achieved using an inoculum 100-fold lower than the ID90 for infection of an undamaged urothelium with the same uropathogens. As the time of catheterization increased, however, colonization by the Gram-positive uropathogen E. faecalis was reduced, whereas catheterization created a sustained window of vulnerability to infection for Gram-negative UPEC over time. As CAUTI contributes to poorer patient outcomes and increased health care expenditures, we tested whether a single prophylactic antibiotic treatment, concurrent with catheterization, would prevent infection. We observed that antibiotic treatment protected against UPEC and E. faecalis bladder and catheter colonization as late as 6 hours after implantation. Thus, our study has revealed a simple, safe, and immediately employable intervention, with the potential to decrease one of the most costly hospital-incurred infections, thereby improving patient and health care economic outcome. PMID- 27699249 TI - A xenograft model of macrophage activation syndrome amenable to anti-CD33 and anti-IL-6R treatment. AB - Transgenic expression of key myelosupportive human cytokines in immune-deficient mice corrects for the lack of cross-species activities of stem cell factor (SCF), IL-3, and GM-CSF. When engrafted with human umbilical cord blood (UCB), these triple-transgenic mice produce BM and spleen grafts with much higher myeloid composition, relative to nontransgenic controls. Shortly after engraftment with UCB, these mice develop a severe, fatal macrophage activation syndrome (MAS) characterized by a progressive drop in rbc numbers, increased reticulocyte counts, decreased rbc half-life, progressive cytopenias, and evidence of chronic inflammation, including elevated human IL-6. The BM becomes strikingly hypocellular, and spleens are significantly enlarged with evidence of extramedullary hematopoiesis and activated macrophages engaged in hemophagocytosis. This manifestation of MAS does not respond to lymphocyte suppressive therapies such as steroids, i.v. immunoglobulin, or antibody-mediated ablation of human B and T cells, demonstrating a lymphocyte-independent mechanism of action. In contrast, elimination of human myeloid cells using gemtuzumab ozogamicin (anti-CD33) completely reversed the disease. Additionally, the IL-6R antibody tocilizumab delayed progression and prolonged lifespan. This new model of MAS provides an opportunity for investigation of the mechanisms driving this disease and for the testing of directed therapies in a humanized mouse. PMID- 27699250 TI - One-time injection of AAV8 encoding urocortin 2 provides long-term resolution of insulin resistance. AB - Using mice rendered insulin resistant with high fat diets (HFD), we examined blood glucose levels and insulin resistance after i.v. delivery of an adeno associated virus type 8 encoding murine urocortin 2 (AAV8.UCn2). A single i.v. injection of AAV8.UCn2-normalized blood glucose and glucose disposal within weeks, an effect that lasted for months. Hyperinsulinemic-euglycemic clamps showed reduced plasma insulin, increased glucose disposal rates, and increased insulin sensitivity following UCn2 gene transfer. Mice with corticotropin releasing hormone type 2-receptor deletion that were rendered insulin resistant by HFD showed no improvement in glucose disposal after UCn2 gene transfer, indicating that the effect requires UCn2's cognate receptor. We also demonstrated increased glucose disposal after UCn2 gene transfer in db/db mice, a second model of insulin resistance. UCn2 gene transfer reduced fatty infiltration of the liver in both models of insulin resistance. UCn2 increases Glut4 translocation to the plasma membrane in skeletal myotubes in a manner quantitatively similar to insulin, indicating a mechanism through which UCn2 operates to increase insulin sensitivity. UCn2 gene transfer, in a dose-dependent manner, is insulin sensitizing and effective for months after a single injection. These findings suggest a potential long-term therapy for clinical type-2 diabetes. PMID- 27699252 TI - Safety and efficacy of the JAK inhibitor tofacitinib citrate in patients with alopecia areata. AB - BACKGROUND: Alopecia areata (AA) is an autoimmune disease characterized by hair loss mediated by CD8+ T cells. There are no reliably effective therapies for AA. Based on recent developments in the understanding of the pathomechanism of AA, JAK inhibitors appear to be a therapeutic option; however, their efficacy for the treatment of AA has not been systematically examined. METHODS: This was a 2 center, open-label, single-arm trial using the pan-JAK inhibitor, tofacitinib citrate, for AA with >50% scalp hair loss, alopecia totalis (AT), and alopecia universalis (AU). Tofacitinib (5 mg) was given twice daily for 3 months. Endpoints included regrowth of scalp hair, as assessed by the severity of alopecia tool (SALT), duration of hair growth after completion of therapy, and disease transcriptome. RESULTS: Of 66 subjects treated, 32% experienced 50% or greater improvement in SALT score. AA and ophiasis subtypes were more responsive than AT and AU subtypes. Shorter duration of disease and histological peribulbar inflammation on pretreatment scalp biopsies were associated with improvement in SALT score. Drug cessation resulted in disease relapse in 8.5 weeks. Adverse events were limited to grade I and II infections. An AA responsiveness to JAK/STAT inhibitors score was developed to segregate responders and nonresponders, and the previously developed AA disease activity index score tracked response to treatment. CONCLUSIONS: At the dose and duration studied, tofacitinib is a safe and effective treatment for severe AA, though it does not result in a durable response. Transcriptome changes reveal unexpected molecular complexity within the disease. TRIAL REGISTRATION: ClinicalTrials.gov NCT02197455 and NCT02312882.

PMID- 27699253 TI - Oral ruxolitinib induces hair regrowth in patients with moderate-to-severe alopecia areata. AB - BACKGROUND. Alopecia areata (AA) is a common autoimmune disease with a lifetime risk of 1.7%; there are no FDA-approved treatments for AA. We previously identified a dominant IFN-gamma transcriptional signature in cytotoxic T lymphocytes (CTLs) in human and mouse AA skin and showed that treatment with JAK inhibitors induced durable hair regrowth in mice by targeting this pathway. Here, we investigated the use of the oral JAK1/2 inhibitor ruxolitinib in the treatment of patients with moderate-to-severe AA. METHODS. We initiated an open-label clinical trial of 12 patients with moderate-to-severe AA, using oral ruxolitinib, 20 mg twice per day, for 3-6 months of treatment followed by 3 months follow-up off drug. The primary endpoint was the proportion of subjects with 50% or greater hair regrowth from baseline to end of treatment. RESULTS. Nine of twelve patients (75%) demonstrated a remarkable response to treatment, with average hair regrowth of 92% at the end of treatment. Safety parameters remained largely within normal limits, and no serious adverse effects were reported. Gene expression profiling revealed treatment-related downregulation of inflammatory markers, including signatures for CTLs and IFN response genes and upregulation of hair-specific markers. CONCLUSION. In this pilot study, 9 of 12 patients (75%) treated with ruxolitinib showed significant scalp hair regrowth and improvement of AA. Larger randomized controlled trials are needed to further assess the safety and efficacy of ruxolitinib in the treatment of AA. TRIAL REGISTRATION. Clinicaltrials.gov NCT01950780. FUNDING.

PMID- 27699251 TI - Cell-type deconvolution with immune pathways identifies gene networks of host defense and immunopathology in leprosy. AB - Transcriptome profiles derived from the site of human disease have led to the identification of genes that contribute to pathogenesis, yet the complex mixture of cell types in these lesions has been an obstacle for defining specific mechanisms. Leprosy provides an outstanding model to study host defense and pathogenesis in a human infectious disease, given its clinical spectrum, which interrelates with the host immunologic and pathologic responses. Here, we investigated gene expression profiles derived from skin lesions for each clinical subtype of leprosy, analyzing gene coexpression modules by cell-type deconvolution. In lesions from tuberculoid leprosy patients, those with the self limited form of the disease, dendritic cells were linked with MMP12 as part of a tissue remodeling network that contributes to granuloma formation. In lesions from lepromatous leprosy patients, those with disseminated disease, macrophages were linked with a gene network that programs phagocytosis. In erythema nodosum leprosum, neutrophil and endothelial cell gene networks were identified as part of the vasculitis that results in tissue injury. The present integrated computational approach provides a systems approach toward identifying cell defined functional networks that contribute to host defense and immunopathology at the site of human infectious disease. PMID- 27699254 TI - Dynamic dual-isotope molecular imaging elucidates principles for optimizing intrathecal drug delivery. AB - The intrathecal (IT) dosing route offers a seemingly obvious solution for delivering drugs directly to the central nervous system. However, gaps in understanding drug molecule behavior within the anatomically and kinetically unique environment of the mammalian IT space have impeded the establishment of pharmacokinetic principles for optimizing regional drug exposure along the neuraxis. Here, we have utilized high-resolution single-photon emission tomography with X-ray computed tomography to study the behavior of multiple molecular imaging tracers following an IT bolus injection, with supporting histology, autoradiography, block-face tomography, and MRI. Using simultaneous dual-isotope imaging, we demonstrate that the regional CNS tissue exposure of molecules with varying chemical properties is affected by IT space anatomy, cerebrospinal fluid (CSF) dynamics, CSF clearance routes, and the location and volume of the injected bolus. These imaging approaches can be used across species to optimize the safety and efficacy of IT drug therapy for neurological disorders. PMID- 27699255 TI - Identifying candidate genes for 2p15p16.1 microdeletion syndrome using clinical, genomic, and functional analysis. AB - The 2p15p16.1 microdeletion syndrome has a core phenotype consisting of intellectual disability, microcephaly, hypotonia, delayed growth, common craniofacial features, and digital anomalies. So far, more than 20 cases of 2p15p16.1 microdeletion syndrome have been reported in the literature; however, the size of the deletions and their breakpoints vary, making it difficult to identify the candidate genes. Recent reports pointed to 4 genes (XPO1, USP34, BCL11A, and REL) that were included, alone or in combination, in the smallest deletions causing the syndrome. Here, we describe 8 new patients with the 2p15p16.1 deletion and review all published cases to date. We demonstrate functional deficits for the above 4 candidate genes using patients' lymphoblast cell lines (LCLs) and knockdown of their orthologs in zebrafish. All genes were dosage sensitive on the basis of reduced protein expression in LCLs. In addition, deletion of XPO1, a nuclear exporter, cosegregated with nuclear accumulation of one of its cargo molecules (rpS5) in patients' LCLs. Other pathways associated with these genes (e.g., NF-kappaB and Wnt signaling as well as the DNA damage response) were not impaired in patients' LCLs. Knockdown of xpo1a, rel, bcl11aa, and bcl11ab resulted in abnormal zebrafish embryonic development including microcephaly, dysmorphic body, hindered growth, and small fins as well as structural brain abnormalities. Our multifaceted analysis strongly implicates XPO1, REL, and BCL11A as candidate genes for 2p15p16.1 microdeletion syndrome. PMID- 27699257 TI - Interleukin-1 signaling contributes to acute islet compensation. AB - IL-1beta is a well-established inducer of both insulin resistance and impaired pancreatic islet function. Despite this, findings examining IL-1 receptor deficiency or antagonism in in vivo animal models, as well as in clinical studies of type 2 diabetic (T2D) patients, have led to conflicting results, suggesting that the actions of IL-1beta on glycemic control may be pleiotropic in nature. In the present work, we find that the ability of IL-1beta to amplify glucose stimulated insulin secretion from human islets correlates with donor BMI. Islets from obese donors are sensitized to the insulinotropic effects of this cytokine, whereas the stimulatory effects of IL-1beta are lost in islets from obese T2D patients, suggesting a role for IL-1 signaling in islet compensation. Indeed, mice deficient in IL-1 receptor type I become glucose intolerant more rapidly than their WT littermates and have impaired secretory responses during the acute stages of inflammatory and metabolic stress induced by LPS and high-fat diet, respectively. IL-1beta directly enhances beta cell insulin secretion by increasing granule docking and soluble N-ethylmaleimide-sensitive factor attachment receptor (SNARE) complex formation at the plasma membrane. Together, our study highlights the importance of IL-1beta signaling in islet compensation to metabolic and inflammatory stress. PMID- 27699256 TI - Claudin-low bladder tumors are immune infiltrated and actively immune suppressed. AB - We report the discovery of a claudin-low molecular subtype of high-grade bladder cancer that shares characteristics with the homonymous subtype of breast cancer. Claudin-low bladder tumors were enriched for multiple genetic features including increased rates of RB1, EP300, and NCOR1 mutations; increased frequency of EGFR amplification; decreased rates of FGFR3, ELF3, and KDM6A mutations; and decreased frequency of PPARG amplification. While claudin-low tumors showed the highest expression of immune gene signatures, they also demonstrated gene expression patterns consistent with those observed in active immunosuppression. This did not appear to be due to differences in predicted neoantigen burden, but rather was associated with broad upregulation of cytokine and chemokine levels from low PPARG activity, allowing unopposed NFKB activity. Taken together, these results define a molecular subtype of bladder cancer with distinct molecular features and an immunologic profile that would, in theory, be primed for immunotherapeutic response. PMID- 27699258 TI - Histone deacetylase inhibitor panobinostat induces calcineurin degradation in multiple myeloma. AB - Multiple myeloma (MM) is a relapsed and refractory disease, one that highlights the need for developing new molecular therapies for overcoming of drug resistance. Addition of panobinostat, a histone deacetylase (HDAC) inhibitor, to bortezomib and dexamethasone improved progression-free survival (PFS) in relapsed and refractory MM patients. Here, we demonstrate how calcineurin, when inhibited by immunosuppressive drugs like FK506, is involved in myeloma cell growth and targeted by panobinostat. mRNA expression of PPP3CA, a catalytic subunit of calcineurin, was high in advanced patients. Panobinostat degraded PPP3CA, a degradation that should have been induced by inhibition of the chaperone function of heat shock protein 90 (HSP90). Cotreatment with HDAC inhibitors and FK506 led to an enhanced antimyeloma effect with a greater PPP3CA reduction compared with HDAC inhibitors alone both in vitro and in vivo. In addition, this combination treatment efficiently blocked osteoclast formation, which results in osteolytic lesions. The poor response and short PFS duration observed in the bortezomib containing therapies of patients with high PPP3CA suggested its relevance to bortezomib resistance. Moreover, bortezomib and HDAC inhibitors synergistically suppressed MM cell viability through PPP3CA inhibition. Our findings underscore the usefulness of calcineurin-targeted therapy in MM patients, including patients who are resistant to bortezomib. PMID- 27699259 TI - Microvascular resistance of the culprit coronary artery in acute ST-elevation myocardial infarction. AB - BACKGROUND: Failed myocardial reperfusion is common and prognostically important after acute ST-elevation myocardial infarction (STEMI). The purpose of this study was to investigate coronary flow reserve (CFR), a measure of vasodilator capacity, and the index of microvascular resistance (IMR; mmHg * s) in the culprit artery of STEMI survivors. METHODS: IMR (n = 288) and CFR (n = 283; mean age [SD], 60 [12] years) were measured acutely using guide wire-based thermodilution. Cardiac MRI disclosed left ventricular pathology, function, and volumes at 2 days (n = 281) and 6 months after STEMI (n = 264). All-cause death or first heart failure hospitalization was independently adjudicated (median follow-up 845 days). RESULTS: Myocardial hemorrhage and microvascular obstruction occurred in 89 (42%) and 114 (54%) patients with evaluable T2*-MRI maps. IMR and CFR were associated with microvascular pathology (none vs. microvascular obstruction only vs. microvascular obstruction and myocardial hemorrhage) (median [interquartile range], IMR: 17 [12.0-33.0] vs. 17 [13.0-39.0] vs. 37 [21.0-63.0], P < 0.001; CFR: 1.7 [1.4-2.5] vs. 1.5 [1.1-1.8] vs. 1.4 [1.0-1.8], P < 0.001), whereas thrombolysis in myocardial infarction blush grade was not. IMR was a multivariable associate of changes in left ventricular end-diastolic volume (regression coefficient [95% CI] 0.13 [0.01, 0.24]; P = 0.036), whereas CFR was not (P = 0.160). IMR (5 units) was a multivariable associate of all-cause death or heart failure hospitalization (n = 30 events; hazard ratio [95% CI], 1.09 [1.04, 1.14]; P < 0.001), whereas CFR (P = 0.124) and thrombolysis in myocardial infarction blush grade (P = 0.613) were not. IMR had similar prognostic value for these outcomes as <50% ST-segment resolution on the ECG. CONCLUSIONS: IMR is more closely associated with microvascular pathology, left ventricular remodeling, and health outcomes than the angiogram or CFR. TRIAL REGISTRATION: NCT02072850.

PMID- 27699261 TI - Anakinra as a diagnostic challenge and treatment option for systemic autoinflammatory disorders of undefined etiology. AB - BACKGROUND: Some adult patients presenting with unexplained pyrexia, serositis, skin rashes, arthralgia, myalgia, and other symptoms commonly found in autoinflammatory disorders may not fit a specific diagnosis, either because their clinical phenotype is nondiagnostic or genetic tests are negative. We used the term undifferentiated systemic autoinflammatory disorder (uSAID) to describe such cases. Given that well-defined autoinflammatory diseases show responses to IL-1 blockade, we evaluated whether anakinra was useful for both diagnosing and treating uSAID patients. METHODS: We performed a retrospective analysis of consecutive patients presenting with uSAID between 2012-2015 who were treated with the recombinant IL-1 receptor antagonist anakinra. uSAID was diagnosed after excluding malignancy, infection, and pathogenic mutations in known hereditary fever syndromes (HFS) genes and where clinical criteria for adult onset Still's disease (AOSD) were not met. RESULTS: A total of 11 patients presented with uSAID (5 males and 6 females), with a mean time to diagnosis of 3.5 years (1-8 years). Patients were unresponsive or only partially controlled on disease-modifying antirheumatic drug (DMARD)/steroid treatment. Anakinra controlled symptoms within 4-6 weeks of starting treatment in 9 of 11 cases. Two patients discontinued therapy - one due to incomplete response and another due to severe injection-site reactions. CONCLUSION: This retrospective case series demonstrates that the spectrum of poorly defined autoinflammatory disorders that show responsiveness to anakinra is considerable. Anakinra seems a viable treatment option for these patients, who are unresponsive to standard steroid/DMARD treatments. Moreover, given the mechanisms of action, response to anakinra implicates underlying IL-1 dysregulation in the disease pathogenesis of responding uSAIDs patients. PMID- 27699260 TI - A cytotoxic anti-IL-3Ralpha antibody targets key cells and cytokines implicated in systemic lupus erythematosus. AB - To date, the major target of biologic therapeutics in systemic lupus erythematosus (SLE) has been the B cell, which produces pathogenic autoantibodies. Recently, targeting type I IFN, which is elaborated by plasmacytoid dendritic cells (pDCs) in response to endosomal TLR7 and TLR9 stimulation by SLE immune complexes, has shown promising results. pDCs express high levels of the IL-3Ralpha chain (CD123), suggesting an alternative potential targeting strategy. We have developed an anti-CD123 monoclonal antibody, CSL362, and show here that it affects key cell types and cytokines that contribute to SLE. CSL362 potently depletes pDCs via antibody-dependent cell-mediated cytotoxicity, markedly reducing TLR7, TLR9, and SLE serum-induced IFN-alpha production and IFN-alpha-upregulated gene expression. The antibody also inhibits TLR7- and TLR9-induced plasmablast expansion by reducing IFN-alpha and IL-6 production. These effects are more pronounced than with IFN-alpha blockade alone, possibly because pDC depletion reduces production of other IFN subtypes, such as type III, as well as non-IFN proinflammatory cytokines, such as IL-6. In addition, CSL362 depletes basophils and inhibits IL-3 signaling. These effects were confirmed in cells derived from a heterogeneous population of SLE donors, various IFN-dependent autoimmune diseases, and healthy controls. We also demonstrate in vivo activity of CSL362 following its s.c. administration to cynomolgus monkeys. This spectrum of effects provides a preclinical rationale for the therapeutic evaluation of CSL362 in SLE. PMID- 27699262 TI - Increased apoptosis and browning of TAK1-deficient adipocytes protects against obesity. AB - Obesity is an increasing health problem worldwide, and nonsurgical strategies to treat obesity have remained rather inefficient. We here show that acute loss of TGF-beta-activated kinase 1 (TAK1) in adipocytes results in an increased rate of apoptotic adipocyte death and increased numbers of M2 macrophages in white adipose tissue. Mice with adipocyte-specific TAK1 deficiency have reduced adipocyte numbers and are resistant to obesity induced by a high-fat diet or leptin deficiency. In addition, adipocyte-specific TAK1-deficient mice under a high-fat diet showed increased energy expenditure, which was accompanied by enhanced expression of the uncoupling protein UCP1. Interestingly, acute induction of adipocyte-specific TAK1 deficiency in mice already under a high-fat diet was able to stop further weight gain and improved glucose tolerance. Thus, loss of TAK1 in adipocytes reduces the total number of adipocytes, increases browning of white adipose tissue, and may be an attractive strategy to treat obesity, obesity-dependent diabetes, and other associated complications. PMID- 27699263 TI - Incomplete clonal deletion as prerequisite for tissue-specific minor antigen tolerization. AB - Central clonal deletion has been considered the critical factor responsible for the robust state of tolerance achieved by chimerism-based experimental protocols, but split-tolerance models and the clinical experience are calling this assumption into question. Although clone-size reduction through deletion has been shown to be universally required for achieving allotolerance, it remains undetermined whether it is sufficient by itself. Therapeutic Treg treatment induces chimerism and tolerance in a stringent murine BM transplantation model devoid of myelosuppressive recipient treatment. In contrast to irradiation chimeras, chronic rejection (CR) of skin and heart allografts in Treg chimeras was permanently prevented, even in the absence of complete clonal deletion of donor MHC-reactive T cells. We show that minor histocompatibility antigen mismatches account for CR in irradiation chimeras without global T cell depletion. Furthermore, we show that Treg therapy-induced tolerance prevents CR in a linked suppression-like fashion, which is maintained by active regulatory mechanisms involving recruitment of thymus-derived Tregs to the graft. These data suggest that highly efficient intrathymic and peripheral deletion of donor reactive T cells for specificities expressed on hematopoietic cells preclude the expansion of donor-specific Tregs and, hence, do not allow for spreading of tolerance to minor specificities that are not expressed by donor BM. PMID- 27699265 TI - Targeting CLEC9A delivers antigen to human CD141+ DC for CD4+ and CD8+T cell recognition. AB - DC-based vaccines that initiate T cell responses are well tolerated and have demonstrated efficacy for tumor immunotherapy, with the potential to be combined with other therapies. Targeting vaccine antigens (Ag) directly to the DCs in vivo is more effective than cell-based therapies in mouse models and is therefore a promising strategy to translate to humans. The human CD141+ DCs are considered the most clinically relevant for initiating CD8+ T cell responses critical for killing tumors or infected cells, and they specifically express the C-type lectin like receptor CLEC9A that facilitates presentation of Ag by these DCs. We have therefore developed a human chimeric Ab that specifically targets CLEC9A on CD141+ DCs in vitro and in vivo. These human chimeric Abs are highly effective at delivering Ag to DCs for recognition by both CD4+ and CD8+ T cells. Given the importance of these cellular responses for antitumor or antiviral immunity, and the superior specificity of anti-CLEC9A Abs for this DC subset, this approach warrants further development for vaccines. PMID- 27699264 TI - Depletion of major pathogenic cells in asthma by targeting CRTh2. AB - Eosinophilic inflammation and Th2 cytokine production are central to the pathogenesis of asthma. Agents that target either eosinophils or single Th2 cytokines have shown benefits in subsets of biomarker-positive patients. More broadly effective treatment or disease-modifying effects may be achieved by eliminating more than one inflammatory stimulator. Here we present a strategy to concomitantly deplete Th2 T cells, eosinophils, basophils, and type-2 innate lymphoid cells (ILC2s) by generating monoclonal antibodies with enhanced effector function (19A2) that target CRTh2 present on all 4 cell types. Using human CRTh2 (hCRTh2) transgenic mice that mimic the expression pattern of hCRTh2 on innate immune cells but not Th2 cells, we demonstrate that anti-hCRTh2 antibodies specifically eliminate hCRTh2+ basophils, eosinophils, and ILC2s from lung and lymphoid organs in models of asthma and Nippostrongylus brasiliensis infection. Innate cell depletion was accompanied by a decrease of several Th2 cytokines and chemokines. hCRTh2-specific antibodies were also active on human Th2 cells in vivo in a human Th2-PBMC-SCID mouse model. We developed humanized hCRTh2-specific antibodies that potently induce antibody-dependent cell cytotoxicity (ADCC) of primary human eosinophils and basophils and replicated the in vivo depletion capacity of their murine parent. Therefore, depletion of hCRTh2+ basophils, eosinophils, ILC2, and Th2 cells with h19A2 hCRTh2-specific antibodies may be a novel and more efficacious treatment for asthma. PMID- 27699266 TI - Cyclosporine A immunosuppression drives catastrophic squamous cell carcinoma through IL-22. AB - Immune-suppressed organ transplant recipients (OTRs) can develop catastrophic squamous cell carcinoma (SCC), characterized by multiple primary tumors, extensive body surface area involvement, or metastases. There are currently no curative systemic therapies available. We previously showed that IL-22 enhances SCC proliferation. Herein, we examined links between cyclosporine (CSA), IL-22, and SCC in patients, cell lines, and mice with UV light-induced SCC. Eighteen of 114 OTRs developed catastrophic SCC, which was strongly associated with CSA treatment. We found that CSA drives T cell polarization toward IL-22-producing T22 cells, and CSA treatment increased IL-22 receptor in SCC cells. SCC tissue from OTRs showed increased expression of IL-22RA1. CSA potentiated rescue by IL 22 of serum-starved SCC cells; treatment of SCC cells with IL-22 and CSA increased both their migratory and invasive capacity. In a UV-induced model of SCC in SKH-1 immunocompetent mice, treatment with anti-IL-22 antibody reduced tumor number and tumor burden. We found that catastrophic SCC in OTRs is associated with CSA use, which may be acting by favoring T22 polarization. Since anti-IL-22 antibody administration decreased tumor number and tumor burden in vivo, blockade of the IL-22 axis may be developed as a viable therapeutic option for catastrophic SCC. PMID- 27699267 TI - Quantitation of circulating satellite RNAs in pancreatic cancer patients. AB - Pancreatic ductal adenocarcinoma (Pdac) is a malignancy with a poor prognosis due to difficulties in early detection. Although promising biomarkers are increasingly reported, such methods are not yet easy to apply clinically, mainly due to their low reproducibility or technical difficulties. In this study, we developed a convenient and sensitive method for quantifying aberrantly expressed satellite repeat RNAs in sera, which can be used to efficiently detect patients with Pdac. Here, we introduce a Tandem Repeat Amplification by nuclease Protection (TRAP) method combined with droplet digital PCR (ddPCR) to detect human satellite II (HSATII) RNAs, which are specifically expressed in human Pdacs at greater levels than normal tissues but are difficult to measure due to their repetitive sequences and irregularities. HSATII RNA core sequence levels in sera were significantly higher in Pdac patients compared with noncancer patients (median copy number: 14.75 and 3.17 per MUl in the training set and 17.35 and 2.9 in the validation set, respectively). In addition, patients with intraductal papillary mucinous neoplasm (IPMN), a precancerous lesion of Pdac, could also be efficiently detected. This method can be routinely applied to screen patients with Pdac and high-risk patients, facilitating the development of preventive medicine for this disease. PMID- 27699268 TI - Paneth cell defects in Crohn's disease patients promote dysbiosis. AB - BACKGROUND: Paneth cell dysfunction has been implicated in a subset of Crohn's disease (CD) patients. We previously stratified clinical outcomes of CD patients by using Paneth cell phenotypes, which we defined by the intracellular distribution of antimicrobial proteins. Animal studies suggest that Paneth cells shape the intestinal microbiome. However, it is unclear whether Paneth cell phenotypes alter the microbiome complexity in CD subjects. Therefore, we analyzed the correlation of Paneth cell phenotypes with mucosal microbiome composition and ileal RNA expression in pediatric CD and noninflammatory bowel disease (non-IBD) patients. METHODS: Pediatric CD (n = 44) and non-IBD (n = 62) patients aged 4 to 18 were recruited prior to routine endoscopic biopsy. Ileal mucosal samples were analyzed for Paneth cell phenotypes, mucosal microbiome composition, and RNA transcriptome. RESULTS: The prevalence of abnormal Paneth cells was higher in pediatric versus adult CD cohorts. For pediatric CD patients, those with abnormal Paneth cells showed significant changes in their ileal mucosal microbiome, highlighted by reduced protective microbes and enriched proinflammatory microbes. Ileal transcriptome profiles showed reduced transcripts for genes that control oxidative phosphorylation in CD patients with abnormal Paneth cells. These transcriptional changes in turn were correlated with specific microbiome alterations. In non-IBD patients, a subset contained abnormal Paneth cells. However, this subset was not associated with alterations in the microbiome or host transcriptome. CONCLUSION: Paneth cell abnormalities in human subjects are associated with mucosal dysbiosis in the context of CD, and these changes are associated with alterations in oxidative phosphorylation, potentially in a feedback loop.

AB - Background. Hypophosphatasia (HPP) is caused by loss-of-function mutation(s) of the gene that encodes the tissue-nonspecific isoenzyme of alkaline phosphatase (TNSALP). Consequently, cell-surface deficiency of TNSALP phosphohydrolase activity leads to extracellular accumulation of inorganic pyrophosphate, a natural substrate of TNSALP and inhibitor of mineralization. Children with HPP can manifest rickets, skeletal pain, deformity, fracture, muscle weakness, and premature deciduous tooth loss. Asfotase alfa is a recombinant, bone-targeted, human TNSALP injected s.c. to treat HPP. In 2012, we detailed the 1-year efficacy of asfotase alfa therapy for the life-threatening perinatal and infantile forms of HPP. Methods. Here, we evaluated the efficacy and safety of asfotase alfa treatment administered to children 6-12 years of age at baseline who were substantially impaired by HPP. Two radiographic scales quantitated HPP skeletal disease, including comparisons to serial radiographs from similarly affected historical control patients. Results. Twelve children receiving treatment were studied for 5 years. The 6-month primary endpoint was met, showing significant radiographic improvement. Additional significant improvements included patient growth, strength, motor function, agility, and quality of life, which for most patients meant achieving normal values for age- and sex-matched peers that were sustained at 5 years of treatment. For most, pain and disability resolved. Mild to moderate injection-site reactions were common and were sometimes associated with lipohypertrophy. Low anti-asfotase alfa antibody titers were noted in all patients. No evidence emerged for clinically important ectopic calcification or treatment resistance. Conclusions. Asfotase alfa enzyme replacement therapy has substantial and sustained efficacy with a good safety profile for children suffering from HPP. Trial Registration.

PMID- 27699269 TI - CRIg-expressing peritoneal macrophages are associated with disease severity in patients with cirrhosis and ascites. AB - Infections are an important cause of morbidity and mortality in patients with decompensated cirrhosis and ascites. Hypothesizing that innate immune dysfunction contributes to susceptibility to infection, we assessed ascitic fluid macrophage phenotype and function. The expression of complement receptor of the immunoglobulin superfamily (CRIg) and CCR2 defined two phenotypically and functionally distinct peritoneal macrophage subpopulations. The proportion of CRIghi macrophages differed between patients and in the same patient over time, and a high proportion of CRIghi macrophages was associated with reduced disease severity (model for end-stage liver disease) score. As compared with CRIglo macrophages, CRIghi macrophages were highly phagocytic and displayed enhanced antimicrobial effector activity. Transcriptional profiling by RNA sequencing and comparison with human macrophage and murine peritoneal macrophage expression signatures highlighted similarities among CRIghi cells, human macrophages, and mouse F4/80hi resident peritoneal macrophages and among CRIglo macrophages, human monocytes, and mouse F4/80lo monocyte-derived peritoneal macrophages. These data suggest that CRIghi and CRIglo macrophages may represent a tissue-resident population and a monocyte-derived population, respectively. In conclusion, ascites fluid macrophage subset distribution and phagocytic capacity is highly variable among patients with chronic liver disease. Regulating the numbers and/or functions of these macrophage populations could provide therapeutic opportunities in cirrhotic patients. PMID- 27699271 TI - TGF-beta and VEGF cooperatively control the immunotolerant tumor environment and the efficacy of cancer immunotherapies. AB - Tregs imprint an early immunotolerant tumor environment that prevents effective antitumor immune responses. Using transcriptomics of tumor tissues, we identified early upregulation of VEGF and TGF-beta pathways compatible with tolerance imprinting. Silencing of VEGF or TGF-beta in tumor cells induced early and pleiotropic modulation of immune-related transcriptome signatures in tumor tissues. These were surprisingly similar for both silenced tumors and related to common downstream effects on Tregs. Silencing of VEGF or TGF-beta resulted in dramatically delayed tumor growth, associated with decreased Tregs and myeloid derived suppressor cells and increased effector T cell activation in tumor infiltrates. Strikingly, co-silencing of TGF-beta and VEGF led to a substantial spontaneous tumor eradication rate and the combination of their respective inhibitory drugs was synergistic. VEGF and/or TGF-beta silencing also restored tumor sensitivity to tumor-specific cell therapies and markedly improved the efficacy of anti-PD-1/anti-CTLA-4 treatment. Thus, TGF-beta and VEGF cooperatively control the tolerant environment of tumors and are targets for improved cancer immunotherapies. PMID- 27699272 TI - Effects of sphingosine-1-phosphate receptor 1 phosphorylation in response to FTY720 during neuroinflammation. AB - Fingolimod (FTY720, Gilenya), a sphingosine-1-phosphate receptor (S1PR) modulator, is one of the first-line immunomodulatory therapies for treatment of relapsing-remitting multiple sclerosis (MS). Human S1PR1 variants have been reported to have functional heterogeneity in vitro, suggesting that S1PR1 function may influence FTY720 efficacy. In this study, we examined the influence of S1PR1 phosphorylation on response to FTY720 in neuroinflammation. We found that mice carrying a phosphorylation-defective S1pr1 gene [S1PR1(S5A) mice] were refractory to FTY720 treatment in MOG35-55-immunized and Th17-mediated experimental autoimmune encephalomyelitis (EAE) models. Long-term treatment with FTY720 induced significant lymphopenia and suppressed Th17 response in the peripheral immune system via downregulating STAT3 phosphorylation in both WT and S1PR1(S5A) mice. However, FTY720 did not effectively prevent neuroinflammation in the S1PR1(S5A) EAE mice as a result of encephalitogenic cells expressing C-C chemokine receptor 6 (CCR6). Combined treatment with FTY720 and anti-CCR6 delayed disease progression in S1PR1(S5A) EAE mice, suggesting that CCR6-mediated cell trafficking can overcome the effects of FTY720. This work may have translational relevance regarding FTY720 efficacy in MS patients and suggests that cell type specific therapies may enhance therapeutic efficacy in MS. PMID- 27699273 TI - CNS-directed gene therapy for the treatment of neurologic and somatic mucopolysaccharidosis type II (Hunter syndrome). AB - Mucopolysaccharidosis type II (MPSII) is an X-linked lysosomal storage disease characterized by severe neurologic and somatic disease caused by deficiency of iduronate-2-sulfatase (IDS), an enzyme that catabolizes the glycosaminoglycans heparan and dermatan sulphate. Intravenous enzyme replacement therapy (ERT) currently constitutes the only approved therapeutic option for MPSII. However, the inability of recombinant IDS to efficiently cross the blood-brain barrier (BBB) limits ERT efficacy in treating neurological symptoms. Here, we report a gene therapy approach for MPSII through direct delivery of vectors to the CNS. Through a minimally invasive procedure, we administered adeno-associated virus vectors encoding IDS (AAV9-Ids) to the cerebrospinal fluid of MPSII mice with already established disease. Treated mice showed a significant increase in IDS activity throughout the encephalon, with full resolution of lysosomal storage lesions, reversal of lysosomal dysfunction, normalization of brain transcriptomic signature, and disappearance of neuroinflammation. Moreover, our vector also transduced the liver, providing a peripheral source of therapeutic protein that corrected storage pathology in visceral organs, with evidence of cross-correction of nontransduced organs by circulating enzyme. Importantly, AAV9-Ids-treated MPSII mice showed normalization of behavioral deficits and considerably prolonged survival. These results provide a strong proof of concept for the clinical translation of our approach for the treatment of Hunter syndrome patients with cognitive impairment. PMID- 27699274 TI - B cells from African American lupus patients exhibit an activated phenotype. AB - Systemic lupus erythematosus (SLE) is a complex systemic autoimmune disease driven by both innate and adaptive immune cells. African Americans tend to present with more severe disease at an earlier age compared with patients of European ancestry. In order to better understand the immunological differences between African American and European American patients, we analyzed the frequencies of B cell subsets and the expression of B cell activation markers from a total of 68 SLE patients and 69 normal healthy volunteers. We found that B cells expressing the activation markers CD86, CD80, PD1, and CD40L, as well as CD19+CD27-IgD- double-negative B cells, were enriched in African American patients vs. patients of European ancestry. In addition to increased expression of CD40L, surface levels of CD40 on B cells were lower, suggesting the engagement of the CD40 pathway. In vitro experiments confirmed that CD40L expressed by B cells could lead to CD40 activation and internalization on adjacent B cells. To conclude, these results indicate that, compared with European American patients, African American SLE patients present with a particularly active B cell component, possibly via the activation of the CD40/CD40L pathway. These data may help guide the development of novel therapies. PMID- 27699277 TI - Potential tree species for use in urban areas in temperate and oceanic climates. AB - This study aims to assess the potential of trees for integration in urban development by evaluating the damage caused by trees in relation to various tree characteristics. Tree damage to permeable pavement systems and other urban structures such as impermeable pavements, kerbs, roads, retaining walls, footpaths, walls and buildings were assessed to identify the most suitable trees for the urban environment. One hundred square sites of 100 m * 100 m were randomly selected in Greater Manchester for this representative example case study to demonstrate the assessment methodology. Among tree species in this study, Acer platanoides L. (Norway maple) occurred most frequently (17%); others were Tilia spp. L. (Lime; 16%), Fraxinus excelsior L. (common ash; 12%), Acer pseudoplatanus L. (sycamore; 10%) and Prunus avium L. (wild cherry; 8%). The study concludes that 44% of the damage was to impermeable pavements and 22% to permeable pavements. Other damage to structures included kerbs (19%), retaining walls (5%), footpaths (4%), roads (3%) and walls (3%). Concerning the severity of damage, 66% were moderate, 21% light and 19% severe. Aesculus hippocastanum L. (horse chestnut) caused the greatest damage (59%) expressed in percentage as a ratio of the tree number related to damage over the corresponding tree number that was found close to structures. PMID- 27699278 TI - Resolving spatiotemporal characteristics of the seasonal hypoxia cycle in shallow estuarine environments of the Severn River and South River, MD, Chesapeake Bay, USA. AB - The nature of emerging patterns concerning water quality stressors and the evolution of hypoxia within sub-estuaries of the Chesapeake Bay has been an important unresolved question among the Chesapeake Bay community. Elucidation of the nature of hypoxia in the tributaries of the Chesapeake Bay has important ramifications to the successful restoration of the Bay, since much of Bay states population lives within the watersheds of the tributaries. Very little to date, is known about the small sub-estuaries of the Chesapeake Bay due to limited resources and the difficulties in resolving both space and time dimensions on scales that are adequate to resolve this question. We resolve the spatio-temporal domain dilemma by setting up an intense monitoring program of water quality stressors in the Severn and South Rivers, MD. Volume rendered models were constructed to allow for a visual dissection of the water quality times series which illustrates the life cycle of hypoxia and anoxia at the mid to upper portions of the tidal tributaries. The model also shows that unlike their larger Virginian tributary counterparts, there is little to no evidence of severe hypoxic water intrusions from the main-stem of the Chesapeake Bay into these sub estuaries. PMID- 27699276 TI - PRL3-zumab, a first-in-class humanized antibody for cancer therapy. AB - Novel, tumor-specific drugs are urgently needed for a breakthrough in cancer therapy. Herein, we generated a first-in-class humanized antibody (PRL3-zumab) against PRL-3, an intracellular tumor-associated phosphatase upregulated in multiple human cancers, for unconventional cancer immunotherapies. We focused on gastric cancer (GC), wherein elevated PRL-3 mRNA levels significantly correlated with shortened overall survival of GC patients. PRL-3 protein was overexpressed in 85% of fresh-frozen clinical gastric tumor samples examined but not in patient matched normal gastric tissues. Using human GC cell lines, we demonstrated that PRL3-zumab specifically blocked PRL-3+, but not PRL-3-, orthotopic gastric tumors. In this setting, PRL3-zumab had better therapeutic efficacy as a monotherapy, rather than simultaneous combination with 5-fluorouracil or 5 fluorouracil alone. PRL3-zumab could also prevent PRL-3+ tumor recurrence. Mechanistically, we found that intracellular PRL-3 antigens could be externalized to become "extracellular oncotargets" that serve as bait for PRL3-zumab binding to potentially bridge and recruit immunocytes into tumor microenvironments for killing effects on cancer cells. In summary, our results document a comprehensive cancer therapeutic approach to specific antibody-targeted therapy against the PRL 3 oncotarget as a case study for developing antibodies against other intracellular targets in drug discovery. PMID- 27699275 TI - Synergy of radiotherapy and PD-1 blockade in Kras-mutant lung cancer. AB - Radiation therapy (RT), a critical modality in the treatment of lung cancer, induces direct tumor cell death and augments tumor-specific immunity. However, despite initial tumor control, most patients suffer from locoregional relapse and/or metastatic disease following RT. The use of immunotherapy in non-small cell lung cancer (NSCLC) could potentially change this outcome by enhancing the effects of RT. Here, we report significant (up to 70% volume reduction of the target lesion) and durable (up to 12 weeks) tumor regressions in conditional Kras driven genetically engineered mouse models (GEMMs) of NSCLC treated with radiotherapy and a programmed cell death 1 antibody (alphaPD-1). However, while alphaPD-1 therapy was beneficial when combined with RT in radiation-naive tumors, alphaPD-1 therapy had no antineoplastic efficacy in RT-relapsed tumors and further induced T cell inhibitory markers in this setting. Furthermore, there was differential efficacy of alphaPD-1 plus RT among Kras-driven GEMMs, with additional loss of the tumor suppressor serine/threonine kinase 11/liver kinase B1 (Stk11/Lkb1) resulting in no synergistic efficacy. Taken together, our data provide evidence for a close interaction among RT, T cells, and the PD-1/PD-L1 axis and underscore the rationale for clinical combinatorial therapy with immune modulators and radiotherapy. PMID- 27699280 TI - PTB and TIAR binding to insulin mRNA 3'- and 5'UTRs; implications for insulin biosynthesis and messenger stability. AB - OBJECTIVES: Insulin expression is highly controlled on the posttranscriptional level. The RNA binding proteins (RBPs) responsible for this result are still largely unknown. METHODS AND RESULTS: To identify RBPs that bind to insulin mRNA we performed mass spectrometry analysis on proteins that bound synthetic oligonucloetides mimicing the 5'- and the 3'-untranslated regions (UTRs) of rat and human insulin mRNA in vitro. We observed that the RBPs heterogeneous nuclear ribonucleoprotein (hnRNP) U, polypyrimidine tract binding protein (PTB), hnRNP L and T-cell restricted intracellular antigen 1-related protein (TIA-1-related protein; TIAR) bind to insulin mRNA sequences, and that the in vitro binding affinity of these RBPs changed when INS-1 cells were exposed to glucose, 3 isobutyl-1-methylxanthine (IBMX) or nitric oxide. High glucose exposure resulted in a modest increase in PTB and TIAR binding to an insulin mRNA sequence. The inducer of nitrosative stress DETAnonoate increased markedly hnRNP U and TIAR mRNA binding. An increased PTB to TIAR binding ratio in vitro correlated with higher insulin mRNA levels and insulin biosynthesis rates in INS-1 cells. To further investigate the importance of RNA-binding proteins for insulin mRNA stability, we decreased INS-1 and EndoC-betaH1 cell levels of PTB and TIAR by RNAi. In both cell lines, decreased levels of PTB resulted in lowered insulin mRNA levels while decreased levels of TIAR resulted in increased insulin mRNA levels. Thapsigargin-induced stress granule formation was associated with a redistribution of TIAR from the cytosol to stress granules. CONCLUSIONS: These experiments indicate that alterations in insulin mRNA stability and translation correlate with differential RBP binding. We propose that the balance between PTB on one hand and TIAR on the other participates in the control of insulin mRNA stability and utilization for insulin biosynthesis. PMID- 27699279 TI - Identification of Leukotoxin and other vaccine candidate proteins in a Mannheimia haemolytica commercial antigen. AB - Bovine Respiratory Disease is the most costly disease that affects beef and dairy cattle industry. Its etiology is multifactorial, arising from predisposing environmental stress conditions as well as the action of several different respiratory pathogens. This situation has hindered the development of effective control strategies. Although different type of vaccines are available, many currently marketed vaccines are based on inactivated cultures of the main viral and bacterial agents involved in this pathology. The molecular composition of commercial veterinary vaccines is a critical issue. The present work aims to define at the proteomic level the most relevant valence of a line of commercial respiratory vaccines widely used in Central and South America. Since Mannheimia haemolytica is responsible for most of the disease associated morbid-mortality, we focused on the main proteins secreted by this pathogen, in particular Leukotoxin A, its main virulence factor. By Western blot analysis and mass spectrometry, Leukotoxin A was identified as a major component of M. haemolytica culture supernatants. We also identified other ten M. haemolytica proteins, including outer membrane proteins, periplasmic transmembrane solute transporters and iron binding proteins, which are relevant to achieve protective immunity against the pathogen. This work allowed a detailed molecular characterization of this vaccine component, providing evidence of its quality and efficacy. Furthermore, our results contributed to the identification of several proteins of interest as subunit vaccine candidates. PMID- 27699281 TI - Greater variation in affect is associated with lower fasting plasma glucose. AB - BACKGROUND: Depression and bipolar illness are associated with a 2-3 fold increase in the prevalence of diabetes. However, it is unknown whether variation in mood affects glucose metabolism. The aim of this study was to assess whether changes in affect were related to fasting plasma glucose and glycated haemoglobin. METHODS: 379 men and 441 women who took part in the 2003 Health Survey for England and had valid data for GHQ12 and fasting blood glucose were included. Mood variability was assessed by the General Health Questionnaire 12 (GHQ12). Fasting plasma glucose and glycated haemoglobin (HbA1c) were measured by standard laboratory methodology and their relationship to variability assessed using linear regression. RESULTS: There was a significant inverse relationship between fasting blood glucose, but not HbA1c, and variability score (R2 = 0.327, p = 0.02) after adjusting for sociodemographic factors, anthropometric measurements, lifestyle, and use of medication. CONCLUSION: This study has shown an inverse association between changes in affect and fasting plasma glucose. This unexpected finding suggests that the association between affect and glucose is more complex than previously thought. Fasting blood glucose may reflect the operation of homeostatic mechanisms that are disturbed in certain mental states and are associated, therefore, with altered risk of diabetes and related metabolic conditions. This may have implications for the management of those with such conditions and with mental disorders. PMID- 27699283 TI - Influence of clinical history on MRI interpretation of optic neuropathy. AB - BACKGROUND AND PURPOSE: Clinical history is known to influence interpretation of a wide range of radiologic examinations. We sought to evaluate the influence of the clinical history on MRI interpretation of optic neuropathy. MATERIALS AND METHODS: 107 consecutive orbital MRI scans were retrospectively reviewed by three neuroradiologists. The readers independently evaluated the coronal STIR sequence for optic nerve hyperintensity and/or atrophy (yes/no) and the coronal post contrast T1WI for optic nerve enhancement (yes/no). Readers initially evaluated the cases blinded to the clinical history. Following a two week washout period, readers again evaluated the cases with the clinical history provided. Inter reader and reader-clinical radiologist agreement was assessed using Cohen's simple kappa coefficient. RESULTS: Intra-reader agreement, without and with provision of clinical history, was 0.564-0.716 on STIR and 0.270-0.495 on post contrast T1WI. Inter-reader agreement was overall fair-moderate. On post-contrast T1WI, inter-reader agreement was significantly higher when the clinical history was provided (p = 0.001). Reader-clinical radiologist agreement improved with provision of the clinical history to the readers on both the STIR and post contrast T1WI sequences. CONCLUSIONS: In the MRI assessment of optic neuropathy, only modest levels of inter-reader agreement were achieved, even after provision of clinical history. Provision of clinical history improved inter-reader agreement, especially when assessing for optic nerve enhancement. These findings confirm the subjective nature of orbital MRI interpretation in cases of optic neuropathy, and point to the importance of an accurate clinical history. Of note, the accuracy of orbital MRI in the context of optic neuropathy was not assessed, and would require further investigation. PMID- 27699282 TI - Use of multiple picosecond high-mass molecular dynamics simulations to predict crystallographic B-factors of folded globular proteins. AB - Predicting crystallographic B-factors of a protein from a conventional molecular dynamics simulation is challenging, in part because the B-factors calculated through sampling the atomic positional fluctuations in a picosecond molecular dynamics simulation are unreliable, and the sampling of a longer simulation yields overly large root mean square deviations between calculated and experimental B-factors. This article reports improved B-factor prediction achieved by sampling the atomic positional fluctuations in multiple picosecond molecular dynamics simulations that use uniformly increased atomic masses by 100 fold to increase time resolution. Using the third immunoglobulin-binding domain of protein G, bovine pancreatic trypsin inhibitor, ubiquitin, and lysozyme as model systems, the B-factor root mean square deviations (mean +/- standard error) of these proteins were 3.1 +/- 0.2-9 +/- 1 A2 for Calpha and 7.3 +/- 0.9-9.6 +/- 0.2 A2 for Cgamma, when the sampling was done for each of these proteins over 20 distinct, independent, and 50-picosecond high-mass molecular dynamics simulations with AMBER forcefield FF12MC or FF14SB. These results suggest that sampling the atomic positional fluctuations in multiple picosecond high-mass molecular dynamics simulations may be conducive to a priori prediction of crystallographic B-factors of a folded globular protein. PMID- 27699284 TI - Beyond waste: new sustainable fillers from fly ashes stabilization, obtained by low cost raw materials. AB - A sustainable economy can be achieved only by assessing processes finalized to optimize the use of resources. Waste can be a relevant source of energy thanks to energy-from-waste processes. Concerns regarding the toxic fly ashes can be solved by transforming them into resource as recycled materials. The commitment to recycle is driven by the need to conserve natural resources, reduce imports of raw materials, save landfill space and reduce pollution. A new method to stabilize fly ash from Municipal Solid Waste Incinerator (MSWI) at room temperature has been developed thanks to COSMOS-RICE LIFE+ project (www.cosmos rice.csmt.eu). This process is based on a chemical reaction that occurs properly mixing three waste fly ashes with rice husk ash, an agricultural by-product. COSMOS inert can replace critical raw materials (i.e. silica, fluorspar, clays, bentonite, antimony and alumina) as filler. Moreover the materials employed in the stabilization procedure may be not available in all areas. This paper investigates the possibility of substituting silica fume with corresponding condensed silica fume and to substitute flue-gas desulfurization (FGD) residues with low-cost calcium hydroxide powder. The removal of coal fly ash was also considered. The results will be presented and a possible substitution of the materials to stabilize fly ash will be discussed. PMID- 27699285 TI - Gamma-tubulin coordinates nuclear envelope assembly around chromatin. AB - The cytosolic role of gamma-tubulin as a microtubule organizer has been studied thoroughly, but its nuclear function is poorly understood. Here, we show that gamma-tubulin is located throughout the chromatin of demembranated Xenopus laevis sperm and, as the nucleus is formed, gamma-tubulin recruits lamin B3 and nuclear membranes. Immunodepletion of gamma-tubulin impairs X. laevis assembly of both the lamina and the nuclear membrane. During nuclear formation in mammalian cell lines, gamma-tubulin establishes a cellular protein boundary around chromatin that coordinates nuclear assembly of the daughter nuclei. Furthermore, expression of a gamma-tubulin mutant that lacks the DNA-binding domain forms chromatin-empty nuclear like structures and demonstrate that a constant interplay between the chromatin-associated and the cytosolic pools of gamma-tubulin is required and, when the balance between pools is impaired, aberrant nuclei are formed. We therefore propose that the nuclear protein meshwork formed by gamma-tubulin around chromatin coordinates nuclear formation in eukaryotic cells. PMID- 27699286 TI - Significant loss of sensitivity and specificity in the taxonomic classification occurs when short 16S rRNA gene sequences are used. AB - The classification performance of Kraken was evaluated in terms of sensitivity and specificity when using short and long 16S rRNA sequences. A total of 440,738 sequences from bacteria with complete taxonomic classifications were downloaded from the high quality ribosomal RNA database SILVA. Amplicons produced (86,371 sequences; 1450 bp) by virtual PCR with primers covering the V1-V9 region of the 16S-rRNA gene were used as reference. Virtual PCRs of internal fragments V3-V4, V4-V5 and V3-V5 were performed. A total of 81,523, 82,334 and 82,998 amplicons were obtained for regions V3-V4, V4-V5 and V3-V5 respectively. Differences in depth of taxonomic classification were detected among the internal fragments. For instance, sensitivity and specificity of sequences classified up to subspecies level were higher when the largest internal fraction (V3-V5) was used (54.0 and 74.6% respectively), compared to V3-V4 (45.1 and 66.7%) and V4-V5 (41.8 and 64.6%) fragments. Similar pattern was detected for sequences classified up to more superficial taxonomic categories (i.e. family, order, class...). Results also demonstrate that internal fragments lost specificity and some could be misclassified at the deepest taxonomic levels (i.e. species or subspecies). It is concluded that the larger V3-V5 fragment could be considered for massive high throughput sequencing reducing the loss of sensitivity and sensibility. PMID- 27699292 TI - Preface.

PMID- 27699295 TI - The Requirements of an Electronic Medical Record to Suit all Clinical Disciplines. AB - The design of the electronic medical record is becoming increasingly sophisticated as techniques develop to improve the understanding of user requirements. Such techniques must develop as it becomes increasingly important to improve the use and uptake of such records. An outstanding question is whether the same electronic medical record can fulfil the requirements of users in different clinical disciplines. To evaluate such a requirement it is necessary to understand the different information management the needs of different clinical disciplines. Only once these differing needs are understood, will it become possible to consider whether a common record is feasible in terms of both data modelling and the user interface. This paper describes the move towards a better understanding of user requirements. It outlines the differences between the requirements of various disciplines and discusses the implications. It concentrates on the differences between the requirements for hospital specialists and family medicine as an example of the problems.

AB - Health-care is a collaborative endeavor involving a number of individuals and organizations with diverse perspectives. Computer-supported collaboration technologies have great potential to enable health-care providers to improve the quality of care provided to their patients. Such technologies have the potential to overcome barriers to quality health-care in the small, scattered populations of rural areas. Rapid changes in technology are making it more and more possible for collaborative telemedicine to be a part of the practice of medicine. The World Wide Web has amply demonstrated that the globe has shrunk and information from afar is a mere mouse click away. However, the ease with which information is accessed along with the potential disclosure and misuse of personal information has raised serious concerns about the ability to restrict such information to legitimate accesses by duly authorized health-care providers. The authors present their experience in developing a health-care collaboration facility, ARTEMIS, which enabled Web-based access to electronic medical records, and provide a vision of their experiment to provide secure telemedicine for rural health-care practitioners. PMID- 27699298 TI - Medical Informatics Education at the University of Manchester. AB - Manchester University offered the first full time, undergraduate Medical Informatics degree programme in the UK. The B.Sc. in Medical Informatics was conceived in 1992 and its first cohort of students, taking the three year version, graduated in 1996; those students taking the four year version of the undergraduate degree will graduate in July 1997. The paper describes our somewhat turbulent experience of the first four years, highlighting both the difficulties and successes of launching an inter-disciplinary degree. First, the story of the programme's development is given by way of an introduction and to establish a suitable context for describing the programme in more detail. Then, after presenting the aim and objectives of the programme, we describe the overall structure of the course, and reflect upon certain key issues for establishing Medical Informatics as a distinct, academic discipline. PMID- 27699299 TI - Health Informatics Training at the University of Missouri. AB - Health informatics training has a long tradition at the University of Missouri. The current program prepares future researchers for the rapidly changing field of health informatics. This paper describes the training program, the fellowships, the interdisciplinary strengths of the program, and representative projects. Research opportunities range from information analyses of basic medical sciences through development of clinical information systems to the evaluation of information systems. The informatics training program at the University of Missouri promotes evidence-based medical informatics and has a strong emphasis on the organizational aspects of successful information system implementation.

AB - Our strategy for adapting a curriculum in medical informatics for medical students is presented. After a brief overview, some specific conditions are addressed, which account for some peculiarities of the objectives of our courses and of the design of the curriculum, including its integration in the overall medical curriculum. Some efforts concerning examinations and some specific educational tools are then discussed. The paper also deals with particular features concerning medical informatics education for dentistry and pharmacy students as well as for postgraduate courses, paying special attention to the doctoral level. Finally, future perspectives of medical informatics education are discussed. The paper does not present a list of successes and achievements. We had, and still have several difficulties (not always related to financial drawbacks), which required a particular approach; the word "strategy'; in the title is also meant to cover these aspects.

PMID- 27699310 TI - Clinical workstations: An architectural prespective. AB - The role of a clinical workstation is examined as an integral part of a larger, clinical information delivery and acquisition system. Different care scenarios and environmental factors influence the behavior of a workstation. The common functional components of a workstation are information resources, application logic and presentation. A workstation is successful when each of its components operates within an information architecture and contributes to meet user needs. New technologies to integrate and display information are making the workstation functions independent of the actual hardware and software platform. PMID- 27699311 TI - Multimedia Workstations: Electronic Assistants for Health-Care Professionals. AB - The increasing costs of health care and the economic reality has produced an interesting paradox for the health professional to perform more clinical work with fewer support personnel. Moreover, an explosion of the knowledge-base that underlies sound clinical care not only makes effective time management critical, but also knowledge management compelling. A multimedia workstation is an electronic assistant for the busy health professional that can help with administrative tasks and give access to clinical information and knowledge networks. The multimedia nature of processed information reflects an evolution of medical technologies that involve more and more complex objects such as video sequences or digitized signals. Analysis of the 445 Medline-indexed publications for the January 1991 to December 1994 period, that included the word "workstation" either in their title or in their abstract, helps in refining objectives and challenges both for health professionals and decision makers. From an engineering perspective, development of a workstation requires the integration into the same environments of tools to localize, access, manipulate and communicate the required information. The long-term goal is to establish an easy access in a collaborative working environment that gives the end-user the feeling of a single virtual health enterprise, driven by an integrated computer system when the information system relies on a set of heterogeneous and geographically distributed components. Consequences in terms of migration from traditional client/server architectures to more client/network architectures are considered. PMID- 27699312 TI - Constructing Workstation Applications: Component Integration Strategies for a Changing Health-Care System. AB - A health-care workstation is the means by which a professional interacts with the information artifacts of health care. However, a major transformation is taking place in the software architecture of health-care systems that alters significantly the role of the workstation. Health-care systems are becoming more complex in response to the need to support "extended enterprises" across regions, and provide both horizontal and vertical integration capabilities. Component based software methodologies are being introduced that match well the needs of these large systems and the component services they must integrate. In the component-based framework, a workstation functions less as a "portal" for information transactions carried out on distant host computers, and more as the "orchestrator" for tasks involved in assembling, organizing, presenting, and manipulating information. Applications residing on workstations access distributed software components that carry out encapsulated functions for the application. Component-integration methodologies include both formal and ad hoc approaches; the principal emerging technologies are the World Wide Web (WWW), CORBA, Java, OLE, and OpenDoc. An emerging strategy appears to be that of developing application integration environments that encompass and support all of these integration methodologies. Component-based approaches also facilitate standardization at the message level, as messages to classes of components can serve to focus such standardization. PMID- 27699313 TI - Medical Images in Integrated Health Care Workstations. AB - The difference between an invention and a discovery is discussed, before turning to the sources of medical images. Next, the ongoing integration of image modalities in clinical routine is reviewed, as well as improvements in diagnosis and therapy planning with the help of better images in inter-connected distributed systems. Current shortcomings of image processing, and the attempts to overcome these shortcomings are presented. Examples of image processing are given, together with a vision on future systems and procedures. PMID- 27699315 TI - Trends in Integrated Clinical Workstations. AB - During the last decade, several projects aiming at integrated clinical workstations have been described and several prototypes have been demonstrated. In most of these projects, the clinical workstation accesses information and functionality provided by the present proprietary legacy systems of health-care institutions. We discuss trends in integrated clinical workstations from the viewpoints of software engineering and integration, considering that the clinical workstation itself basically consists of three layers: a presentation layer, a data integration layer, and a communication layer. The software engineering view on clinical workstations focuses on the development of basic building blocks from which clinical workstations, specific to a particular medical domain, can be composed. The integration view on clinical workstations addresses methods and techniques to deal with the, in general, intrinsically closed information systems in health-care institutions.

AB - Coordination of activities among information workers and services, tracking and managing activities, and intelligent distribution of information are essential to the efficient operation of any large enterprise. This is particularly important in the healthcare domain, where many different organizations must cooperate to provide patient care reliably in a dynamically changing environment. In this review paper we present a distributed system that supports cooperative problem solving, activity management, and intelligent delivery of information in dynamic and unreliable environments. The system consists of a network of task/context managers (TCMs). Each TCM manages a group of related agents. It maintains up-to date information on availability, operational status, and activities of participating agents, and it acts as a mediator between service requesters and service providers. In addition, the TCM acts as a representative for its agents with other TCMs, allowing different groups of agents to collaborate with one another. This paper describes the system architecture, its implementation and capabilities including matchmaking, plan monitoring, and failure recovery. Our system has been used in prehospital emergency patient information management applications. PMID- 27699317 TI - Integrating Informatics into the Undergraduate Curriculum: A Report on a Pilot Project. AB - Previous case reports in this series on Education and Training have looked at specialist courses for postgraduate students seeking an in-depth knowledge of informatics and a career in the field. By contrast, this review describes a project designed to pilot a series of learning opportunities for undergraduate medical students. Although some UK medical colleges have opted to introduce informatics into the curriculum as a discipline in its own right, the Informatics Department at St Bartholomew's Hospital Medical College chose a different approach. When a new curriculum was introduced at St Bartholomew's and at The London Hospital Medical College, the Head of the Informatics Department saw this as an ideal opportunity to explore ways of integrating informatics into the curriculum. The initiatives described in this paper were made possible as a result of an award from the UK government Department of Employment. Money from an Enterprise in Higher Education grant funded a range of programmes, one of which was designed to introduce students to selected aspects of informatics and to demonstrate what is feasible in the undergraduate curriculum. The work carried out over a period of three and a half years was intended to provide the basis for the next phase of curriculum development. However, in the wake of the restructuring which has taken place in London medical colleges, the Informatics Department at what was St Bartholomew's has relocated to University College London Medical School, and is now called The Centre for Health Informatics and Multiprofessional Education (CHIME). University College is designing a new medical curriculum and CHIME is drawing on the experience gained through the Enterprise Project to find the best way to integrate informatics into this curriculum.

PMID- 27699320 TI - Health Informatics at the University Of Victoria. AB - The University of Victoria has the only program in Canada offering a Bachelor of Science degree in Health Information Science. To meet the requirements of the degree, students must complete 60 units of course work (normally 40 courses) and 4 CO-OP work terms over 4.3 years. The School admits approximately 30 students each year. Seventy-five percent of the students come from British Columbia, ranging in age from 18 to 50 years with the average age being 26 years. In addition to recent high school graduates, over 40% have previous degrees or diplomas, and 65% have over 5 years of work experience. The School's teaching team consists of 4 full-time faculty, 2 professional staff, 2 clerical staff, 7 adjunct faculty and a variable number of sessional teaching staff. The majority of the faculty have health backgrounds, totalling 150 person-years of health care experience. As of November 1995, the School had 168 graduates 75% of whom are employed in British Columbia, 17% in other parts of Canada and 8% outside the country. Sixty-five percent of the graduates work in government departments including community health agencies; 10% work in hospitals, 20% work for management consulting firms, software houses, or computer hardware firms, and 5% are otherwise employed. Almost 100% of the graduates are gainfully employed in professional positions in which their health information science degree is valued. They work as systems analysts, system designers/developers, consultants, research assistants, health-care planners, information system-support staff/trainers and client-account representatives. Some are already in senior management positions. PMID- 27699323 TI - Biomedical Information Systems. PMID- 27699322 TI - Computer-based Patient Records.

AB - Evidence-based medicine is growing in immune thrombocytopenia (ITP), but solid clinical data are still lacking in many areas. A majority of children has self limited ITP, but chronic symptomatic ITP exists also in pediatrics. Management includes a watch-and-wait strategy for children with newly diagnosed ITP and no or mild bleeding, and immunoglobulins and corticosteroids, if more bleeding and mucous membrane involvement is present. Treatment endpoints differ in clinical research and in clinical practice. The requirement of platelet enhancing drugs needs to be better defined in guidelines. Second-line therapies for children are rarely required and include thrombopoietin-receptor agonists, rituximab, dexamethasone and immunosuppressants. Thrombopoietin-receptor agonists are successful in adult but also in pediatric ITP. The strategical position of splenectomy differs from that in adults. Although effective in children it is less frequently used because of its life-long cumulative risk of infectious diseases and a higher potential of spontaneous remission in ITP, providing a strong argument to defer splenectomy. The rarity of ITP makes clinical research expensive. PMID- 27699331 TI - Medical Informatics Training and Research at Rennes University School of Medicine.

PMID- 27699334 TI - Health Informatics Education and Research at the University of Athens. AB - In Europe, coordinated activities in healthcare informatics education started in the late 1980s with the establishment of European courses in health telematics. At the same time the European Commission foresaw the need for spreading the knowledge of Information Technology (IT) in the healthcare sector. Therefore the EC, since then, has supported the initiatives that aim to create awareness, stimulate diffusion, and educated and train the users (healthcare professionals) in the application of IT in health care [I]. Initiatives, such as the NIGHTINGALE project, are essential for the planning and implementation of strategies for training the nursing profession in using and applying healthcare information systems. Other projects are the IT EDUCTRA project, which is a practical project in the field of education and training of healthcare professionals in information technologies, and the ERASMUS Master's Course, which aims at giving those working (or intending to work) in the health service and related activities, a broad, advanced postgraduate education in health informatics.

The interest of the many actors involved in health cards (healthcare authorities, insurance companies, social security agencies, standardization bodies, manufacturers, system integrators, etc.) is focusing increasingly on the role that the health card may have as an enabling component within the global communication and information system that will interconnect all points of care and services in a national healthcare system. PMID- 27699337 TI - Finding Medical Resources on the Internet. AB - As in every other segment of the Internet, the amount of health-care information has increased exponentially in the past five years. Research-oriented, clinical oriented and education-oriented medical resources have been built on the Internet by companies and institutions. Thousands of major medical web sites are currently serving millions of documents on the Internet, which are likely to double in the next 20 months. While the Internet is becoming the largest medical information repository, it is necessary that health-care professionals know efficient ways to find what they want in the vast field of medical information. This paper discusses the categorization, searching mechanisms and the impact of medical resources on the Internet. PMID- 27699338 TI - Networks: The "Fabric of Life" for Informatics Applications.

AB - Patient-centered information systems augment traditional approaches to health information management with specific functions designed to support patient participation in health care decision making and treatment activities. In addition to computer-based record systems and business management applications, patient-centered information systems must include functionality that support communication between clinician and patient, and that provide information and peer support in a timely fashion to the patient. Current progress in information systems demonstrates the existence and feasibility of consumer health informatics, patient access to computerized clinical records, and technical and organizational solutions to integrating computerized patient information systems. We are now proposing a model of patient-centered system that incorporates all those components, and provides a vision of the future.

PMID- 27699350 TI - Electronic Healthcare Records: an essential part of Health Telematics Applications. AB - A healthcare record should ideally be a repository of data, describing a person's health and how it is being supported; and not, as it is now, describing a person's diseases and treatment only. The healthcare record is the basis for monitoring and decisions. Therefore it should be open and available to all authorized health professionals and to the patient. To make this easier is one of the major advantages of electronic healthcare records (EHCR). The computer-based patient record could make major contributions to improving the healthcare system. This is the motivation to initiatives, projects and routine implementations of electronic patient records. The European Union and national initiatives have put major efforts into the support of this main field of medical information processing.

PMID- 27699355 TI - Twenty Five Years of Medical Informatics Education at Heidelberg/Heilbronn: Discussion of a Specialized Curriculum for Medical Informatics. AB - The specialized university curriculum for medical informatics (MI) at the University of Heidelberg/School of Technology Heilbronn is one of the oldest educational approaches in the field of medical informatics, and has been successful for 25 years with about 1,000 graduates (Diplom-lnformatikerin der Medizin or Diplomlnformatiker der Medizin). It belongs to the category of dedicated master's programs for medical informatics and is based on the concept of medical informatics as a medical discipline in its own right. The curriculum is oriented towards the total spectrum of medical informatics ranging from health care economics, biosignal and medical image processing, medical documentation, to information and knowledge processing in medicine. It is a 4.5-year program with strong emphasis on the methodological foundations of medical informatics and on practical education in a number of specific laboratories. Thirty-five students are admitted each semester, and in total about 440 students are enrolled. The faculty consists of 17 full-time members and about 25 parttime lecturers.We report on characteristics, structure and contents of the new 5th version of the curriculum and discuss the features of a specialized curriculum for medical informatics with respect to the challenges for medical informatics in the 21st century.

PMID- 27699389 TI - Data Linkage Strategies to Advance Youth Suicide Prevention: A Systematic Review for a National Institutes of Health Pathways to Prevention Workshop. AB - Background: Linking national, state, and community data systems to data from prevention programs could allow for longer-term assessment of outcomes and evaluation of interventions to prevent suicide. Purpose: To identify and describe data systems that can be linked to data from prevention studies to advance youth suicide prevention research. Data Sources: A systematic review, an environmental scan, and a targeted search were conducted to identify prevention studies and potentially linkable external data systems with suicide outcomes from January 1990 through December 2015. Study Selection: Studies and data systems had to be U.S.-based and include persons aged 25 years or younger. Data systems also had to include data on suicide, suicide attempt, or suicidal ideation. Data Extraction: Information about participants, intervention type, suicide outcomes, primary analytic method used for linkage, statistical approach, analyses performed, and characteristics of data systems was abstracted by 2 reviewers. Data Synthesis: Of 47 studies (described in 59 articles) identified in the systematic review, only 6 were already linked to data systems. A total of 153 unique and potentially linkable data systems were identified, but only 66 were classified as "fairly accessible" and had data dictionaries available. Of the data systems identified, 19% were established primarily for research, 11% for clinical care or operations, 29% for administrative services (such as billing), and 52% for surveillance. About one third (37%) provided national data, 12% provided regional data, 63% provided state data, and 41% provided data below the state level (some provided coverage for >1 geographic unit). Limitation: Only U.S.-based studies published in English were included. Conclusion: There is untapped potential to evaluate and enhance suicide prevention efforts by linking suicide prevention data with existing data systems. However, sparse availability of data dictionaries and lack of adherence to standard data elements limit this potential. Primary Funding Source: Agency for Healthcare Research and Quality. PMID- 27699390 TI - Multiplexed fluorescence mediated tomography with temporal and spectral data. AB - We recently developed an algorithm for multiplexed fluorescence tomographic imaging of at least four fluorophores concurrently in the red and near-infrared wavelength region by jointly using spectral and temporal data. We report the design of a fluorescence tomography instrument that acquires spectral and temporal data, and validate its use in tissue-mimicking phantoms with four embedded fluorescent targets with highly overlapped spectral signatures. Critically, this requires measurement or computation of extended fluorophore signature libraries, which capture the variability in the measured signal due to the unknown position of the targets in the media. We demonstrate that we can demix and tomographically image all four fluorophores with zero image cross-talk, and 1 mm or better spatial resolution.

Twelve percent of U.S. adults have diabetes and another 37% have impaired fasting glucose or impaired glucose tolerance. Diabetes is a major risk factor for such outcomes as cardiovascular disease, blindness, chronic kidney disease, and limb amputation. An important consideration is whether screening for abnormal glucose levels or diabetes reduces cardiovascular or all-cause morbidity and mortality. In October 2015, the U.S. Preventive Services Task Force published recommendations on screening for abnormal blood glucose and concluded that intensive lifestyle interventions have a moderate benefit in reducing progression to diabetes in patients who have abnormal blood glucose levels detected by screening. It found inadequate evidence that such screening reduces cardiovascular or all-cause mortality and no evidence of psychological or other harms from screening. The Task Force recommends glucose screening every 3 years for adults aged 40 to 70 years who are overweight or obese and do not have symptoms of diabetes. In this article, we present the case of a man who meets these criteria and explore his preferences and concerns regarding screening. Two experts then debate screening merits and benefits, the significance of abnormal blood glucose levels and diabetes as cardiovascular risk factors, and application of the guidelines to this particular patient.

PMID- 27699405 TI - Paucibacterial Microbiome and Resident DNA Virome of the Healthy Conjunctiva. AB - Purpose: To characterize the ocular surface microbiome of healthy volunteers using a combination of microbial culture and high-throughput DNA sequencing techniques. Methods: Conjunctival swab samples from 107 healthy volunteers were analyzed by bacterial culture, 16S rDNA gene deep sequencing (n = 89), and biome representational in silico karyotyping (BRiSK; n = 80). Swab samples of the facial skin (n = 42), buccal mucosa (n = 50), and environmental controls (n = 27) were processed in parallel. 16S rDNA gene quantitative PCR was used to calculate the bacterial load in each site. Bacteria were characterized by site using principal coordinate analysis of metagenomics data. BRiSK data were analyzed for presence of fungi and viruses. Results: Corynebacteria, Propionibacteria, and coagulase-negative Staphylococci were the predominant organisms identified by all three techniques. Quantitative 16S PCR demonstrated approximately 0.1 bacterial 16S rDNA/human actin copy on the ocular surface compared with greater than 10 16S rDNA/human actin copy for facial skin or the buccal mucosa. The conjunctival bacterial community structure is distinct compared with the facial skin (R = 0.474, analysis of similarities P = 0.0001), the buccal mucosa (R = 0.893, P = 0.0001), and environmental control samples (R = 0.536, P = 0.0001). 16S metagenomics revealed substantially more bacterial diversity on the ocular surface than other techniques, which appears to be artifactual. BRiSK revealed presence of torque teno virus (TTV) on the healthy ocular surface, which was confirmed by direct PCR to be present in 65% of all conjunctiva samples tested. Conclusions: Relative to adjacent skin or other mucosa, healthy ocular surface microbiome is paucibacterial. Its flora are distinct from adjacent skin. Torque teno virus is a frequent constituent of the ocular surface microbiome. (ClinicalTrials.gov number, NCT02298881.). PMID- 27699409 TI - Is Suppression Just Normal Dichoptic Masking? Suprathreshold Considerations. AB - Purpose: Amblyopic patients have a deficit in visual acuity and contrast sensitivity in their amblyopic eye as well as suppression of the amblyopic eye input under binocular viewing conditions. In this study we wanted to assess the origin of the amblyopic suppression by studying the contrast perception of the amblyopic eye at suprathreshold levels under binocular and monocular viewing. Methods: Using a suprathreshold contrast matching task in which the reference and target stimuli were presented to different eyes either simultaneously or successively, we measured interocular contrast matching in 10 controls and 11 amblyopes (mean age 35 +/- 15; 5 strabismics; 3 anisometropes; 3 mixed). This was then used as an index of the binocular balance across spatial frequency and compared against the contrast sensitivity ratio measured with the same stimuli. Results: We observed that binocular matching becomes more imbalanced at high spatial frequency for amblyopes, compared with controls; that this imbalance did not depend in either group on whether the stimuli were presented simultaneously or successively; and that for both modes of presentation the matching balance correlates well with the interocular contrast sensitivity ratio (mean correlation coefficient of the slopes R = 0.7125). Conclusions: The results from our amblyopes show comparable losses of contrast perception at and above threshold under these binocular viewing conditions across a wide spatial frequency range, much stronger than that observed for our controls. This occurs under conditions in which there should be no dichoptic masking. Furthermore, the matching contrast could be well predicted by the monocular contrast sensitivity. Altogether, this suggests that amblyopic suppression cannot be explained by normal dichoptic masking but rather an attenuation of the input. PMID- 27699407 TI - In Vivo Brillouin Analysis of the Aging Crystalline Lens. AB - Purpose: To analyze the age dependence of the longitudinal modulus of the crystalline lens in vivo using Brillouin scattering data in healthy subjects. Methods: Brillouin scans were performed along the crystalline lens in 56 eyes from 30 healthy subjects aged from 19 to 63 years. Longitudinal elastic modulus was acquired along the sagittal axis of the lens with a transverse and axial resolution of 4 and 60 MUm, respectively. The relative lens stiffness was computed, and correlations with age were analyzed. Results: Brillouin axial profiles revealed nonuniform longitudinal modulus within the lens, increasing from a softer periphery toward a stiffer central plateau at all ages. The longitudinal modulus at the central plateau showed no age dependence in a range of 19 to 45 years and a slight decrease with age from 45 to 63 years. A significant intersubject variability was observed in an age-matched analysis. Importantly, the extent of the central stiff plateau region increased steadily over age from 19 to 63 years. The slope of change in Brillouin modulus in the peripheral regions were nearly age-invariant. Conclusions: The adult human lens showed no measurable age-related increase in the peak longitudinal modulus. The expansion of the stiff central region of the lens is likely to be the major contributing factor to age-related lens stiffening. Brillouin microscopy may be useful in characterizing the crystalline lens for the optimization of surgical or pharmacological treatments aimed at restoring accommodative power. PMID- 27699408 TI - Automated Quantification of Nonperfusion in Three Retinal Plexuses Using Projection-Resolved Optical Coherence Tomography Angiography in Diabetic Retinopathy. AB - Purpose: The purpose of this study was to evaluate an automated algorithm for detecting avascular area (AA) in optical coherence tomography angiograms (OCTAs) separated into three individual plexuses using a projection-resolved technique. Methods: A 3 * 3 mm macular OCTA was obtained in 13 healthy and 13 mild nonproliferative diabetic retinopathy (NPDR) participants. A projection-resolved algorithm segmented OCTA into three vascular plexuses: superficial, intermediate, and deep. An automated algorithm detected AA in each of the three plexuses that were segmented and in the combined inner-retinal angiograms. We assessed the diagnostic accuracy of extrafoveal and total AA using segmented and combined angiograms, the agreement between automated and manual detection of AA, and the within-visit repeatability. Results: The sum of extrafoveal AA from the segmented angiograms was larger in the NPDR group by 0.17 mm2 (P < 0.001) and detected NPDR with 94.6% sensitivity (area under the receiver operating characteristic curve [AROC] = 0.99). In the combined inner-retinal angiograms, the extrafoveal AA was larger in the NPDR group by 0.01 mm2 (P = 0.168) and detected NPDR with 26.9% sensitivity (AROC = 0.62). The total AA, inclusive of the foveal avascular zone, in the segmented and combined angiograms, detected NPDR with 23.1% and 7.7% sensitivity, respectively. The agreement between the manual and automated detection of AA had a Jaccard index of >0.8. The pooled SDs of AA were small compared with the difference in mean for control and NPDR groups. Conclusions: An algorithm to detect AA in OCTA separated into three individual plexuses using a projection-resolved algorithm accurately distinguishes mild NPDR from control eyes. Automatically detected AA agrees with manual delineation and is highly repeatable. PMID- 27699410 TI - Carbonic Anhydrase Inhibitors for the Treatment of Cystic Macular Lesions in Children With X-Linked Juvenile Retinoschisis. AB - Purpose: Little is known regarding the therapeutic effect of carbonic anhydrase inhibitors (CAIs) in the management of cystic macular lesions in children with X linked juvenile retinoschisis (XLRS) despite the fact that this disease often manifests during childhood. Therefore, our goal was to determine the efficacy of CAIs in the treatment of cystic macular lesions in children with XLRS. Methods: We used CAIs to treat cystic macular lesions in 18 eyes of nine children with XLRS. We evaluated the therapeutic effect of CAI treatment with the best corrected visual acuity and foveal zone thickness (FZT) with spectral-domain optical coherence tomography. A reduction of at least 22.4% in FZT was defined as objective evidence of response. Results: Five of nine (55.6%) XLRS patients showed a significant reduction of FZT in both eyes over a median treatment interval of 6.8 months (range, 1-23). In four of five (80.0%) patients, this reduction was already apparent after 1 month of treatment. An improvement of visual acuity was observed in five eyes (27.8%) of three patients (33.3%). Six patients (66.6%) reported minor side effects. Conclusions: Treatment with CAIs decreased FZT in more than half of the children with XLRS. This effect was observed within 1 month in the majority of patients. Carbonic anhydrase inhibitor treatment restores retinal anatomy and may contribute to creating optimal circumstances for gene therapy. PMID- 27699411 TI - Rapid, Dynamic Activation of Muller Glial Stem Cell Responses in Zebrafish. AB - Purpose: Zebrafish neurons regenerate from Muller glia following retinal lesions. Genes and signaling pathways important for retinal regeneration in zebrafish have been described, but our understanding of how Muller glial stem cell properties are regulated is incomplete. Mammalian Muller glia possess a latent neurogenic capacity that might be enhanced in regenerative therapies to treat degenerative retinal diseases. Methods: To identify transcriptional changes associated with stem cell properties in zebrafish Muller glia, we performed a comparative transcriptome analysis from isolated cells at 8 and 16 hours following an acute photic lesion, prior to the asymmetric division that produces retinal progenitors. Results: We report a rapid, dynamic response of zebrafish Muller glia, characterized by activation of pathways related to stress, nuclear factor kappaB (NF-kappaB) signaling, cytokine signaling, immunity, prostaglandin metabolism, circadian rhythm, and pluripotency, and an initial repression of Wnt signaling. When we compared publicly available transcriptomes of isolated mouse Muller glia from two retinal degeneration models, we found that mouse Muller glia showed evidence of oxidative stress, variable responses associated with immune regulation, and repression of pathways associated with pluripotency, development, and proliferation. Conclusions: Categories of biological processes/pathways activated following photoreceptor loss in regeneration-competent zebrafish Muller glia, which distinguished them from mouse Muller glia in retinal degeneration models, included cytokine signaling (notably NF-kappaB), prostaglandin E2 synthesis, expression of core clock genes, and pathways/metabolic states associated with pluripotency. These regulatory mechanisms are relatively unexplored as potential mediators of stem cell properties likely to be important in Muller glial cells for successful retinal regeneration. PMID- 27699412 TI - Adipose-Derived Mesenchymal Stem Cells Reduce Lymphocytic Infiltration in a Rabbit Model of Induced Autoimmune Dacryoadenitis. AB - Purpose: To investigate the immunoregulatory roles of adipose-derived mesenchymal stem cells (ADSCs) in autoimmune dacryoadenitis. Methods: Rabbits were treated with ADSCs or phosphate-buffered solution on days 1, 3, 5, 7, and 9 after injection of activated peripheral blood lymphocytes, and clinical scores were determined by assessing tear production, break-up time, and fluorescein and hematoxylin and eosin staining. Inflammatory response was determined by measuring the expression of different mediators of inflammation in the lacrimal glands. The Th1/Th17-mediated autoreactive responses were evaluated by determining the proliferative response and the expression of cytokine genes and the lineage determining transcription factors. The frequency of regulatory T cells (Tregs) was also examined. Results: The ADSC-treated rabbits showed decreased autoimmune responses, and the secretory function of their lacrimal gland was restored significantly. Treatment with ADSCs downregulated the Th1 and Th17 responses but enhanced Tregs function. In addition, ADSC treatment noticeably suppressed the expression of matrix metalloproteinase (MMP)-9, MPP-2, IL-1beta, and IL-6, whereas it enhanced the expression of the anti-inflammatory cytokine IL-10. Conclusions: Our results demonstrated that ADSC administration efficiently ameliorates autoimmune dacryoadenitis mainly via modulating Th1/Th17 responses. PMID- 27699413 TI - On the Maintenance of Normal Ocular Dominance and a Possible Mechanism Underlying Refractive Adaptation. AB - Purpose: Do humans with uncorrected anisometropia who have not developed anisometropic amblyopia exhibit a shift in ocular dominance nonetheless, reflecting a more subtle form of deprivation? Also, is such a change in dominance, if it occurs, permanent or could it be rectified by an extended period of optical correction? Methods: A total of 25 normal controls (27.5 +/- 2.1 years; mean +/- SD); 28 anisometropes (20.7 +/- 5.6 years) who were fully corrected for more than 16 weeks prior to this investigation; and 24 anisometropes who had never been corrected (21.2 +/- 9.8 years) participated in this study. Sensory eye dominance of observers was measured using the binocular phase combination paradigm to find an interocular contrast ratio at which the contributions of each eye to the binocularly fused percept were equal (i.e., the balance point measure of ocular dominance). Results: Controls exhibited a balance point close to unity (0.91 +/- 0.05), while the two groups of anisometropes exhibited a clear binocular imbalance (uncorrected anisometropes, 0.51 +/- 0.28; corrected anisometropes, 0.70 +/- 0.19); both were significantly different from controls (P < 0.001). The imbalance was less severe in corrected anisometropes compared with uncorrected anisometropes (P = 0.004). Conclusions: We find that anisometropia is associated with an ocular imbalance even in the absence of amblyopia. This abnormality is weaker in anisometropes who have worn an optical correction for some time, suggestive that a better optical status leads to a better binocular status. PMID- 27699414 TI - Progression of Late-Onset Stargardt Disease. AB - Purpose: Identification of sensitive biomarkers is essential to determine potential effects of emerging therapeutic trials for Stargardt disease. This study aimed to describe the natural history of late-onset Stargardt, and demonstrates the accuracy of retinal pigment epithelium (RPE) atrophy progression as an outcome measure. Methods: We performed a retrospective cohort study collecting multicenter data from 47 patients (91 eyes) with late-onset Stargardt, defined by clinical phenotype, at least one ABCA4 mutation, and age at disease onset >= 45 years. We analyzed RPE atrophy progression on fundus autofluorescence and near-infrared reflectance imaging using semiautomated software and a linear mixed model. We performed sample size calculations to assess the power in a simulated 2-year interventional study and assessed visual endpoints using time-to event analysis. Results: Over time, progression of RPE atrophy was observed (mean: 0.22 mm/year, 95% confidence interval [CI]: 0.19-0.27). By including only patients with bilateral RPE atrophy in a future trial, 32 patients are needed to reach a power of 83.9% (95% CI: 83.1-84.6), assuming a fixed therapeutic effect size of 30%. We found a median interval between disease onset and visual acuity decline to 20/32, 20/80, and 20/200 of 2.74 (95% CI: 0.54-4.41), 10.15 (95% CI: 6.13-11.38), and 11.38 (95% CI: 6.13-13.34) years, respectively. Conclusions: We show that RPE atrophy represents a robust biomarker to monitor disease progression in future therapeutic trials. In contrast, the variability in terms of the course of visual acuity was high. PMID- 27699415 TI - Diagnosing Sporadic Creutzfeldt-Jakob Disease by the Detection of Abnormal Prion Protein in Patient Urine. AB - Importance: Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder associated with the accumulation of infectious abnormal prion protein through a mechanism of templated misfolding. A recent report has described the detection of abnormal prion protein in the urine of patients with variant CJD (vCJD) using protein misfolding by cyclic amplification, which was apparently absent in the more common sporadic form of CJD (sCJD). A noninvasive diagnostic test could improve early diagnosis of sCJD and, by screening donations, mitigate the potential risks of prion transmission through human urine-derived pharmaceuticals. Here, we describe the adaptation of the direct detection assay, developed originally as a blood test for vCJD, for the detection of disease associated prion protein in urine samples from patients with sCJD. Objective: To determine the feasibility of sCJD diagnosis by adaptation of an established vCJD diagnostic blood test to urine. Design, Setting, and Participants: This retrospective, cross-sectional study included anonymized urine samples from healthy nonneurological control individuals (n = 91), patients with non-prion neurodegenerative diseases (n = 34), and patients with prion disease (n = 37) of which 20 had sCJD. Urine samples obtained during the Medical Research Council PRION-1 Trial, the National Prion Monitoring Cohort Study, and/or referred to the National Prion Clinic or Dementia Research Centre at the National Hospital for Neurology and Neurosurgery in the United Kingdom. Main Outcomes and Measures: Presence of sCJD infection determined by an assay that captures, enriches, and detects disease-associated prion protein isoforms. Results: A total of 162 samples were analyzed, composed of 91 normal control individuals (51 male, 33 female, and 7 not recorded), 34 neurological disease control individuals (19 male and 15 female), and 37 with prion disease (22 male and 15 female). The assay's specificity for prion disease was 100% (95% CI, 97%-100%), with no false-positive reactions from 125 control individuals, including 34 from a range of neurodegenerative diseases. In contrast to a previous study, which used a different method, sensitivity to vCJD infection was low (7.7%; 95% CI, 0.2%-36%), with only 1 of 13 patients with positive test results, while sensitivity to sCJD was unexpectedly high at 40% (95% CI, 19%-64%). Conclusions and Relevance: We determined 40% of sCJD urine sample results as positive. To our knowledge, this is the first demonstration of an assay that can detect sCJD infection in urine or any target analyte outside of the central nervous system. Urine detection could allow the development of rapid, molecular diagnostics for sCJD and has implications for other neurodegenerative diseases where disease-related assemblies of misfolded proteins might also be present in urine.

AB - The National Institutes of Health (NIH) Pathways to Prevention Workshop "Advancing Research to Prevent Youth Suicide" was cosponsored by the NIH Office of Disease Prevention, National Institute of Mental Health, National Institute on Drug Abuse, and National Center for Complementary and Integrative Health. A multidisciplinary working group developed the agenda, and an evidence-based practice center prepared an evidence report that addressed data systems relevant to suicide prevention efforts through a contract with the Agency for Healthcare Research and Quality. During the workshop, experts discussed the evidence and participants commented during open forums. After considering the data from the evidence report, expert presentations, and public comments, an independent panel prepared a draft report that was posted on the NIH Office of Disease Prevention Web site for 5 weeks for public comment. This abridged version of the final report provides a road map for optimizing youth suicide prevention efforts by highlighting strategies for guiding the next decade of research in this area. These strategies include recommendations for improving data systems, enhancing data collection and analysis methods, and strengthening the research and practice community.

AB - Adaptation is a phenomenological umbrella term under which a variety of temporal contextual effects are grouped. Previous models have shown that some aspects of visual adaptation reflect optimal processing of dynamic visual inputs, suggesting that adaptation should be tuned to the properties of natural visual inputs. However, the link between natural dynamic inputs and adaptation is poorly understood. Here, we extend a previously developed Bayesian modeling framework for spatial contextual effects to the temporal domain. The model learns temporal statistical regularities of natural movies and links these statistics to adaptation in primary visual cortex via divisive normalization, a ubiquitous neural computation. In particular, the model divisively normalizes the present visual input by the past visual inputs only to the degree that these are inferred to be statistically dependent. We show that this flexible form of normalization reproduces classical findings on how brief adaptation affects neuronal selectivity. Furthermore, prior knowledge acquired by the Bayesian model from natural movies can be modified by prolonged exposure to novel visual stimuli. We show that this updating can explain classical results on contrast adaptation. We also simulate the recent finding that adaptation maintains population homeostasis, namely, a balanced level of activity across a population of neurons with different orientation preferences. Consistent with previous disparate observations, our work further clarifies the influence of stimulus-specific and neuronal-specific normalization signals in adaptation.

AB - Methylene blue was the first synthetic drug ever used in medicine, having been used to treat clinical pain syndromes, malaria, and psychotic disorders more than one century ago. Methylene blue is a cationic thiazine dye with redox-cycling properties and a selective affinity for the nervous system. This drug also inhibits the activity of monoamine oxidase, nitric oxide synthase, and guanylyl cyclase, as well as tau protein aggregation; increases the release of neurotransmitters, such as serotonin and norepinephrine; reduces amyloid-beta levels; and increases cholinergic transmission. The action of methylene blue on multiple cellular and molecular targets justifies its investigation in various neuropsychiatric disorders. Investigations of methylene blue were instrumental in the serendipitous development of phenothiazine antipsychotic drugs. Although chlorpromazine is heralded as the first antipsychotic drug used in psychiatry, methylene blue is a phenothiazine drug that had been used to treat psychotic patients half a century earlier. It has also been studied in bipolar disorder and deserves further investigation for the treatment of unipolar and bipolar disorders. More recently, methylene blue has been the subject of preclinical and clinical investigations for cognitive dysfunction, dementia, and other neurodegenerative disorders.

AB - Implementation of the Six Core Strategies to Reduce the Use of Seclusion and Restraint (Six Core Strategies) at a recovery-oriented, tertiary level mental health care facility and the resultant changes in mechanical restraint and seclusion incidents are described. Strategies included increased executive participation; enhanced staff knowledge, skills, and attitudes; development of restraint orders and decision support in the electronic medical record to enable informed debriefing and tracking of events; and implementation of initiatives to include service users and their families in the plan of care. Strategies were implemented in a staged manner across 3 years. The total number of mechanical restraint and seclusion incidents decreased by 19.7% from 2011/12 to 2013/14. Concurrently, the average length of a mechanical restraint or seclusion incident decreased 38.9% over the 36-month evaluation period. Implementation of the Six Core Strategies for restraint minimization effectively decreased the number and length of mechanical restraint and seclusion incidents in a specialized mental health care facility.

AB - In psychiatric-mental health, creating an innovative strategy to help students learn content that may not be frequently seen in a clinical setting is challenging. Thus, simulation helps narrow this gap. Using Kirkpatrick and Kirkpatrick's model of evaluation to guide the current study, faculty contacted baccalaureate nursing program graduates who completed a psychiatric-mental health clinical simulation scenario featuring a hanging suicide and wrist cutting suicide attempt scenario in the "Behind the Door" series as part of the clinical component of their undergraduate psychiatric-mental health course. Eleven nurses responded to a survey regarding their post-graduate encounters with these types of clinical situations, and their perception of recall and application of knowledge and skills acquired during the simulation experience to the clinical situation. Nursing graduates' responses are expressed through three major themes: emotional, contextual/behavioral, and assessment outcomes. Data from the survey indicate that nursing graduates perceived the "Behind the Door" simulations as beneficial to nursing practice. This perception is important in evaluating knowledge transfer from a simulation experience as a student into application in nursing practice.

AB - Antipsychotic medications pose a significant risk to older adult patients with dementia and are frequently prescribed as first-line treatment for behaviors associated with dementia in skilled nursing facilities (SNFs). SNFs are often cited by the Centers for Medicare & Medicaid for inappropriate antipsychotic medication use. The purpose of the current article is to communicate an evidence based practice (EBP) clinical protocol that can guide clinicians away from prescribing antipsychotic medications in the treatment of dementia behaviors. A literature review of 17 rigorous research studies was conducted to determine psychotropic risk and efficacy in treating dementia behaviors. An EBP clinical protocol establishing a hierarchy of psychotropic medications based on risk and efficacy was developed to guide clinicians away from the use of antipsychotic medications and toward the use of potentially safer and more efficacious psychotropic medications in dementia treatment while offering flexibility for clinical judgment.

OBJECTIVES Explain the recommended framework in teaching and implementing interprofessional competencies. Identify suggested core competencies to implement interprofessional collaborative practice. DISCLOSURE STATEMENT Neither the planners nor the author have any conflicts of interest to disclose. BACKGROUND: The aim of this study is to develop and contextualize a competency framework for interprofessional teamwork in Iran. METHOD: The study was conducted in three phases. First, the competencies of interprofessional teamwork were extracted from the literature. In the second phase, the content validity of the initial framework was assessed by the experts through the Delphi rounds. Content validity ratio (CVR) and item-level content validity index (I-CVI) were used for quantitative analysis. Finally, in the third phase, the importance and utility of interprofessional teamwork competencies were assessed by the experts. RESULTS: Initial framework was constructed with 28 competencies. Quantitative analysis by CVR indicated a score of less than .49 for three items. These items were excluded from the framework. The I-CVI for all items in the framework was higher than .78. The final framework was developed and validated with 16 competencies. DISCUSSION: The developed framework is recommended for teaching and assessment of interprofessional teamwork competencies.

AB - This study developed a Web-based type 2 diabetes education program (WB-DEP) for health care professionals. The methodology consisted of a pretest-posttest quasi experimental approach. The study group consisted of 44 nurses and six midwives who volunteered for the study. The WB-DEP was developed in accordance with the effective teaching design model of Morrison, Ross, and Kemp. Data for the study were collected using the Information Form, The Section Evaluation Tests, the Web Based Teaching Material Evaluation Scale, and the WB-DEP Opinion Form. In the statistical evaluation of the data, the averages, percentages, frequencies, and mean values were calculated, and the Wilcoxon signed-rank test was also used. According to the results, the study group believed that the WB-DEP was generally useful, successful, beneficial, informative, and understandable. In addition, the WB-DEP was found to significantly increase participants' knowledge about diabetes. J Contin Educ Nurs. 2016;47(10):464-471.

AB - Best practices for urinary catheter insertion and care are well documented in the literature. However, the development of educational methods to address best practice standards has been relatively stagnant. A novel educational approach to teach practicing providers proper catheter insertion and care was developed under a blended learning model with online videos and hands-on simulations. The education was custom created for each participant role. This education also highlighted the providers' own hospitals' catheter-associated urinary tract infections (CAUTI) rates, the negative patient outcomes that have occurred as a result of CAUTIs, and the financial burdens caused by CAUTIs. Results showed a significant inverse relationship between whether the education was occurring and the number of monthly CAUTIs. The results provided evidence that engaging frontline workers in blended learning catheter care simulation education was significantly associated with a lower number of monthly CAUTIs. Other institutions can design similar educational interventions to reduce their CAUTI rates. J Contin Educ Nurs. 2016;47(10):473-476.

AB - Soil bacteria are very important in biogeochemical cycles and play significant role in soil-borne disease suppression. Although continuous cropping is responsible for soil-borne disease enrichment, its effect on tobacco plant health and how soil bacterial communities change are yet to be elucidated. In this study, soil bacterial communities across tobacco continuous cropping time-series fields were investigated through high-throughput sequencing of 16S ribosomal RNA genes. The results showed that long-term continuous cropping could significantly alter soil microbial communities. Bacterial diversity indices and evenness indices decreased over the monoculture span and obvious variations for community structures across the three time-scale tobacco fields were detected. Compared with the first year, the abundances of Arthrobacter and Lysobacter showed a significant decrease. Besides, the abundance of the pathogen Ralstonia spp. accumulated over the monoculture span and was significantly correlated with tobacco bacterial wilt disease rate. Moreover, Pearson's correlation demonstrated that the abundance of Arthrobacter and Lysobacter, which are considered to be beneficial bacteria had significant negative correlation with tobacco bacterial wilt disease. Therefore, after long-term continuous cropping, tobacco bacterial wilt disease could be ascribed to the alteration of the composition as well as the structure of the soil microbial community.

AB - Thurincin H is a bacteriocin synthesized by some strains of Bacillus thuringiensis. In this study, the thurincin H genetic cassette, which contains ten genes, from a Mexican strain of B. thuringiensis subsp. morrisoni (Btm) was cloned and sequenced. To study the function of the thnR gene component in the cassette, we generated various constructs with or without thnR for expression in Btm. All transformants harboring thnR in recombinant plasmids showed a decrease of ~15 to ~90 % in inhibitory activity against the target strain, Bacillus cereus 183. Importantly, a ~90 % reduction in inhibition occurred with Btm harboring a construct containing thnR alone, suggesting that ThnR, indeed, functions as a negative transcription regulator of the thurincin H cassette. Based on sequence homology, ThnR was classified as a member of the YtrA subfamily of the GntR superfamily of transcriptional regulators. PMID- 27699439 TI - Historical perspective on the "discovery" of the anterolateral ligament of the knee. AB - : There is a lively debate about the existence, origins and discoverer of the anterolateral ligament of the knee. The complex anatomy of the lateral aspect of the knee has made it difficult to differentiate between various structures such as the iliotibial band, capsulo-osseous layer, Kaplan's fibres and the anterolateral capsule. The "discovery" of a new anterolateral structure in 2013 was the culmination of many historical studies. In 1879, Paul Ferdinand Segond described a tibial plateau fracture in which he noted a pearly band reinforcing the joint capsule. Other anatomists had their suspicions about this ligament; it was described by Vallois in 1914 in his thesis and extensively studied by Jost in 1921. References to it can be found in comparative anatomy studies. This historical review serves as a reminder that understanding and treating knee sprains is not something new. LEVEL OF EVIDENCE: V. PMID- 27699440 TI - Are milk and alternatives and fruit and vegetable intakes during adolescence associated with cortical and trabecular bone structure, density, and strength in adulthood? AB - : We investigated the impact of food group intake during adolescence on bone structure and strength during adulthood. In females, we found a beneficial effect of adolescent milk and alternatives and fruit and vegetable intake on adult radius shaft and distal tibia bone structure, respectively. No association was observed in males. INTRODUCTION: The purpose of this study was to investigate whether adolescents with high intake of milk and alternatives (M&A) or fruit and vegetables (F&V) had better adult bone structure and strength compared to those with low intake levels. METHODS: We analyzed data from 47 males and 69 females enrolled in the Pediatric Bone Mineral Accrual Study (PBMAS 1991-2011), who had one peripheral quantitative computed tomography scan at age 29 +/- 2 years. We measured radius and tibia shaft total area (ToA), cortical area (CoA), cortical content (CoC), cortical density, bone strength (SSIp), and muscle area, as well as distal radius and tibia ToA, total density, trabecular area, trabecular content, trabecular density, and bone strength (BSIc). Sequential 24-h recalls were used to assess M&A and F&V intake; participants were grouped for their mean intake during adolescence (low = bottom quartile, moderate = middle quartiles, high = top quartile) and were compared using multivariate analysis of covariance while adjusting for adult height, muscle area, physical activity, energy and calcium intake and adolescent energy intake, and physical activity. RESULTS: Females with high M&A intake compared to low M&A intake group (mean 3.8 vs. 1.3 servings/day, respectively) had greater adult ToA (14 %, p < 0.05), CoA (15 %, p < 0.01), and CoC (16 %, p < 0.01) at radius shaft. Females with moderate F&V intake compared to low F&V intake group (mean 3.7 vs. 2.1 servings/day, respectively) had greater adult ToA (8.5 %, p < 0.05) at distal tibia. CONCLUSION: Higher intake of M&A or F&V during adolescence had a long-term beneficial effect on bone structure in females, an association not observed in males.

AB - : A model-based cost-effectiveness analysis was performed to evaluate the cost effectiveness of secondary fracture prevention by osteoporosis liaison service (OLS) relative to no therapy in patients with osteoporosis and a history of hip fracture. Secondary fracture prevention by OLS is cost-effective in Japanese women with osteoporosis who have suffered a hip fracture. INTRODUCTION: The purpose of this study was to estimate, from the perspective of Japan's healthcare system, the cost-effectiveness of secondary fracture prevention by OLS relative to no therapy in patients with osteoporosis and a history of hip fracture. METHODS: A patient-level state transition model was developed to predict lifetime costs and quality-adjusted life years (QALYs) in patients with or without secondary fracture prevention by OLS. The incremental cost-effectiveness ratio (ICER) of secondary fracture prevention compared with no therapy was estimated. Sensitivity analyses were performed to examine the influence of parameter uncertainty on the base case results. RESULTS: Compared with no therapy, secondary fracture prevention in patients aged 65 with T-score of -2.5 resulted in an additional lifetime cost of $3396 per person and conferred an additional 0.118 QALY, resulting in an ICER of $28,880 per QALY gained. Deterministic sensitivity analyses showed that treatment duration and offset time strongly affect the cost-effectiveness of OLS. According to the results of scenario analyses, secondary fracture prevention by OLS was cost-saving compared with no therapy in patients with a family history of hip fracture and high alcohol intake. CONCLUSIONS: Secondary fracture prevention by OLS is cost-effective in Japanese women with osteoporosis who have suffered a hip fracture. In addition, secondary fracture prevention is less expensive than no therapy in high-risk patients with multiple risk factors. PMID- 27699442 TI - Associations between autistic traits and fractional anisotropy values in white matter tracts in a nonclinical sample of young adults. AB - Whereas a number of studies have examined relationships among brain activity, social cognitive skills, and autistic traits, fewer studies have evaluated whether structural connections among brain regions relate to these traits and skills. Uncinate fasciculus (UF) and inferior longitudinal fasciculus (ILF) are white matter tracts that may underpin the behavioral expression of these skills because they connect regions within or provide sensory information to brain areas implicated in social cognition, and structural differences in these tracts have been associated with autistic traits. We examined relationships among self reported autistic traits, mentalizing, and water diffusivity in UF and ILF in a nonclinical sample of 24 young adults (mean age = 21.92 years, SD = 4.72 years; 15 women). We measured autistic traits using the Autism-Spectrum Quotient, and we measured mentalizing using the Dynamic Interactive Shapes Clips task. We used Tract-Based Spatial Statistics and randomize to examine relationships among fractional anisotropy (FA) values in bilateral ILF and UF, age, cognitive abilities, autistic traits, and mentalizing. Autistic traits were positively related to FA values in left ILF. No other relationships between FA values and other variables were significant. Results suggest that left ILF may be involved in the expression of autistic traits in individuals without clinical diagnoses.

AB - We conducted a systematic literature review to identify and critically evaluate studies of serious adverse health effects (SAHEs) in humans using nicotine replacement therapy (NRT) products. Serious adverse health effects refer to adverse events, leading to substantial disruption of the ability to conduct normal life functions. Strength of evidence evaluations and conclusions were also determined for the identified SAHEs. We evaluated 34 epidemiological studies and clinical trials, relating NRT use to cancer, reproduction/development, CVD, stroke and/or other SAHEs in patients, and four meta-analyses on effects in healthy populations. The overall evidence suffers from many limitations, the most significant being the short-term exposure (<=12 weeks) and follow-up to NRT product use in most of the studies, the common failure to account for changes in smoking behaviour following NRT use, and the sparse information on SAHEs by type of NRT product used. The only SAHE from NRT exposure we identified was an increase in respiratory congenital abnormalities reported in one study. Limited evidence indicated a lack of effect between NRT exposure and SAHEs for CVD and various reproduction/developmental endpoints. For cancer, stroke and other SAHEs, the evidence was inadequate to demonstrate any association with NRT use. Our conclusions agree with recent statements from authoritative bodies. PMID- 27699444 TI - The safety of nanostructured synthetic amorphous silica (SAS) as a food additive (E 551). AB - KEY MESSAGES: Particle sizes of E 551 products are in the micrometre range. The typical external diameters of the constituent particles (aggregates) are greater than 100 nm. E 551 does not break down under acidic conditions such as in the stomach, but may release dissolved silica in environments with higher pH such as the intestinal tract. E 551 is one of the toxicologically most intensively studied substances and has not shown any relevant systemic or local toxicity after oral exposure. Synthetic amorphous silica (SAS) meeting the specifications for use as a food additive (E 551) is and has always been produced by the same two production methods: the thermal and the wet processes, resulting in E 551 products consisting of particles typically in the micrometre size range. The constituent particles (aggregates) are typically larger than 100 nm and do not contain discernible primary particles. Particle sizes above 100 nm are necessary for E 551 to fulfil its technical function as spacer between food particles, thus avoiding the caking of food particles. Based on an in-depth review of the available toxicological information and intake data, it is concluded that the SAS products specified for use as food additive E 551 do not cause adverse effects in oral repeated-dose studies including doses that exceed current OECD guideline recommendations. In particular, there is no evidence for liver toxicity after oral intake. No adverse effects have been found in oral fertility and developmental toxicity studies, nor are there any indications from in vivo studies for an immunotoxic or neurotoxic effect. SAS is neither mutagenic nor genotoxic in vivo. In intact cells, a direct interaction of unlabelled and unmodified SAS with DNA was never found. Differences in the magnitude of biological responses between pyrogenic and precipitated silica described in some in vitro studies with murine macrophages at exaggerated exposure levels seem to be related to interactions with cell culture proteins and cell membranes. The in vivo studies do not indicate that there is a toxicologically relevant difference between SAS products after oral exposure. It is noted that any silicon dioxide product not meeting established specifications, and/or produced to provide new functionality in food, requires its own specific safety and risk assessment.

AB - CRISPR/Cas (clustered regularly interspaced short palindromic repeats/CRISPR associated) adaptive immune systems constitute a bacterial defence against invading nucleic acids derived from bacteriophages or plasmids. This prokaryotic system was adapted in molecular biology and became one of the most powerful and versatile platforms for genome engineering. CRISPR/Cas9 is a simple and rapid tool which enables the efficient modification of endogenous genes in various species and cell types. Moreover, a modified version of the CRISPR/Cas9 system with transcriptional repressors or activators allows robust transcription repression or activation of target genes. The simplicity of CRISPR/Cas9 has resulted in the widespread use of this technology in many fields, including basic research, biotechnology and biomedicine.

AB - Intensive chemotherapy directed against acute myeloid leukemia of childhood is followed by profound neutropenia and high risk for bacterial and fungal infections, including viridans group streptococci as a common cause for gram positive septicemia. Few retrospective studies have shown the efficacy of various antibiotic prophylactic regimens in children. We retrospectively studied 50 pediatric patients treated on the AML-BFM 2004 protocol between 2005 and 2015 at St. Anna Children's Hospital and assessed the effect of antibiotic prophylaxis on the frequency of febrile neutropenia and bacterial sepsis. Fifty pediatric patients underwent 199 evaluable chemotherapy cycles. Viridans sepsis occurred after none of 98 cycles with prophylactic administration of teicoplanin/vancomycin in comparison to 12 cases of viridans sepsis among 79 cycles without systemic antibacterial prophylaxis (0 vs. 15 %, p < 0.0001). In addition, there were significantly fewer episodes of febrile neutropenia in the teicoplanin/vancomycin group (44 % vs. no prophylaxis 82 %, p < 0.0001). Severity of infection seemed to be worse when no antibiotic prophylaxis had been administered with a higher rate of intensive care unit treatment (0/98, 0 %, vs. 4/79, 5 %, p = 0.038). So far, no increase of vancomycin-resistant enterococcus isolates in surveillance cultures was noticed. Antibiotic prophylaxis with teicoplanin (or vancomycin) appears safe and feasible and resulted in eradication of viridans sepsis and decreased incidence of febrile neutropenia in pediatric AML patients. The possibility to administer teicoplanin on alternate days on an outpatient basis or at home could contribute to patient's quality of life and decrease health care costs.

The coils were analyzed for organics (allethrin, permethrin, and butylated hydroxytoluene) and heavy metals (Cr, Co, As, Cd, and Pb) by GC-MS and ICP-MS, respectively. Allethrin was the only target organic compound detected in all mosquito coils with concentrations ranging from ~1900 to ~4500 ug/g. The concentrations of heavy metals varied as follows (in ug/g): Cr: 2.9-9.4, Co: 0.1-1.2, Cu: 0.7-16.1, Se: 0.10-0.4, Ni: 2.1 5.8, As: 0.10-2.2, Cd: 0.10-0.2, and Pb: 1.1-3.6.

AB - Estimating consumer exposure to nanomaterials (NMs) in food products and predicting their toxicological properties are necessary steps in the assessment of the risks of this technology. To this end, analytical methods have to be available to detect, characterize and quantify NMs in food and materials related to food, e.g. food packaging and biological samples following metabolization of food. The challenge for the analytical sciences is that the characterization of NMs requires chemical as well as physical information. This article offers a comprehensive analysis of methods available for the detection and characterization of NMs in food and related products. Special attention was paid to the crucial role of sample preparation methods since these have been partially neglected in the scientific literature so far. The currently available instrumental methods are grouped as fractionation, counting and ensemble methods, and their advantages and limitations are discussed. We conclude that much progress has been made over the last 5 years but that many challenges still exist. Future perspectives and priority research needs are pointed out. Graphical Abstract Two possible analytical strategies for the sizing and quantification of Nanoparticles: Asymmetric Flow Field-Flow Fractionation with multiple detectors (allows the determination of true size and mass-based particle size distribution); Single Particle Inductively Coupled Plasma Mass Spectrometry (allows the determination of a spherical equivalent diameter of the particle and a number-based particle size distribution).

AB - Monitoring the successful removal of antibiotics in waste and surface waters is of high interest to overcome the occurrence of antibacterial resistance in the ecosystem. Among the newly developed analytical methods, the lab-on-a-chip surface-enhanced Raman spectroscopic (LoC-SERS) technique has gained the interest of the scientific community in the last few years. Ciprofloxacin, a second generation fluoroquinolone, is widely used and administered to patients in dosages up to 1000 mg. In addition, more than 50 % of the antibiotic is excreted in urine as the parental drug. Thus, ciprofloxacin in environmental samples may exceed the minimum inhibitory concentration (MIC) values. The present study aims to assess the potential of the LoC-SERS technique to detect the target analyte in spiked river water samples at MIC concentrations. As sample clean-up procedure, a simple filtration is proposed, while as SERS, active substrates silver nanoparticles prepared at room temperature are employed. Ciprofloxacin was successfully quantified in the 0.7-10 MUM concentration range with data that were measured on two different days. Furthermore, because of the low solubility of the antibiotic at the neutral pH range, insights into the effect of pH on the SERS signal of the target molecule are also presented.

AB - The main function of the cystic fibrosis transmembrane conductance regulator (CFTR) is as an ion channel for the movement of small anions across epithelial cell membranes. As an ion channel, CFTR must form a continuous pathway across the cell membrane-referred to as the channel pore-for the rapid electrodiffusional movement of ions. This review summarizes our current understanding of the architecture of the channel pore, as defined by electrophysiological analysis and molecular modeling studies. This includes consideration of the characteristic functional properties of the pore, definition of the overall shape of the entire extent of the pore, and discussion of how the molecular structure of distinct regions of the pore might control different facets of pore function. Comparisons are drawn with closely related proteins that are not ion channels, and also with structurally unrelated proteins with anion channel function. A simple model of pore function is also described. PMID- 27699453 TI - Mechanosensor polycystin-1 potentiates differentiation of human osteoblastic cells by upregulating Runx2 expression via induction of JAK2/STAT3 signaling axis. AB - Polycystin-1 (PC1) has been proposed as a chief mechanosensing molecule implicated in skeletogenesis and bone remodeling. Mechanotransduction via PC1 involves proteolytic cleavage of its cytoplasmic tail (CT) and interaction with intracellular pathways and transcription factors to regulate cell function. Here we demonstrate the interaction of PC1-CT with JAK2/STAT3 signaling axis in mechanically stimulated human osteoblastic cells, leading to transcriptional induction of Runx2 gene, a master regulator of osteoblastic differentiation. Primary osteoblast-like PC1-expressing cells subjected to mechanical-stretching exhibited a PC1-dependent increase of the phosphorylated(p)/active form of JAK2. Specific interaction of PC1-CT with pJAK2 was observed after stretching while pre treatment of cells with PC1 (anti-IgPKD1) and JAK2 inhibitors abolished JAK2 activation. Consistently, mechanostimulation triggered PC1-mediated phosphorylation and nuclear translocation of STAT3. The nuclear phosphorylated(p)/DNA-binding competent pSTAT3 levels were augmented after stretching followed by elevated DNA-binding activity. Pre-treatment with a STAT3 inhibitor either alone or in combination with anti-IgPKD1 abrogated this effect. Moreover, PC1-mediated mechanostimulation induced elevation of Runx2 mRNA levels. ChIP assays revealed direct regulation of Runx2 promoter activity by STAT3/Runx2 after mechanical-stretching that was PC1-dependent. Our findings show that mechanical load upregulates expression of Runx2 gene via potentiation of PC1 JAK2/STAT3 signaling axis, culminating to possibly control osteoblastic differentiation and ultimately bone formation.

AB - CFTR biogenesis starts with its co-translational insertion into the membrane of endoplasmic reticulum and folding of the cytosolic domains, towards the acquisition of a fully folded compact native structure. Efficiency of this process is assessed by the ER quality control system that allows the exit of folded proteins but targets unfolded/misfolded CFTR to degradation. If allowed to leave the ER, CFTR is modified at the Golgi and reaches the post-Golgi compartments to be delivered to the plasma membrane where it functions as a cAMP- and phosphorylation-regulated chloride/bicarbonate channel. CFTR residence at the membrane is a balance of membrane delivery, endocytosis, and recycling. Several adaptors, motor, and scaffold proteins contribute to the regulation of CFTR stability and are involved in continuously assessing its structure through peripheral quality control systems. Regulation of CFTR biogenesis and traffic (and its dysregulation by mutations, such as the most common F508del) determine its overall activity and thus contribute to the fine modulation of chloride secretion and hydration of epithelial surfaces. This review covers old and recent knowledge on CFTR folding and trafficking from its synthesis to the regulation of its stability at the plasma membrane and highlights how several of these steps can be modulated to promote the rescue of mutant CFTR. PMID- 27699456 TI - Diagnosis and management of skin and soft tissue infections in the intensive care unit: a review. AB - PURPOSE: To review the salient features of the diagnosis and management of the most common skin and soft tissue infections (SSTI). This review focuses on severe SSTIs that require care in an intensive care unit (ICU), including toxic shock syndrome, myonecrosis/gas gangrene, and necrotizing fasciitis. METHODS: Guidelines, expert opinion, and local institutional policies were reviewed. RESULTS: Severe SSTIs are common and their management complex due to regional variation in predominant pathogens and antimicrobial resistance patterns, as well as variations in host immune responses. Unique aspects of care for SSTIs in the ICU are discussed, including the role of prosthetic devices, risk factors for bacteremia, and the need for surgical consultation. SSTI mimetics, the role of dermatologic consultation, and the unique features of SSTIs in immunocompromised hosts are also described. CONCLUSIONS: We provide recommendations for clinicians regarding optimal SSTI management in the ICU setting. PMID- 27699457 TI - The rate of brain death and organ donation in patients resuscitated from cardiac arrest: a systematic review and meta-analysis. AB - BACKGROUND: The occurrence of brain death in patients with hypoxic-ischaemic brain injury after resuscitation from cardiac arrest creates opportunities for organ donation. However, its prevalence is currently unknown. METHODS: Systematic review. MEDLINE via PubMed, ISI Web of Science and the Cochrane Database of Systematic Reviews were searched for eligible studies (2002-2016). The prevalence of brain death in adult patients resuscitated from cardiac arrest and the rate of organ donation among brain dead patients were summarised using a random effect model with double-arcsine transformation. The quality of evidence (QOE) was evaluated according to the GRADE guidelines. RESULTS: 26 studies [16 on conventional cardiopulmonary resuscitation (c-CPR), 10 on extracorporeal CPR (e CPR)] included a total of 23,388 patients, 1830 of whom developed brain death at a mean time of 3.2 +/- 0.4 days after recovery of circulation. The overall prevalence of brain death among patients who died before hospital discharge was 12.6 [10.2-15.2] %. Prevalence was significantly higher in e-CPR vs. c-CPR patients (27.9 [19.7-36.6] vs. 8.3 [6.5-10.4] %; p < 0.0001). The overall rate of organ donation among brain dead patients was 41.8 [20.2-51.0] % (9/26 studies, 1264 patients; range 0-100 %). The QOE was very low for both outcomes. CONCLUSIONS: In patients with hypoxic-ischaemic brain injury following CPR, more than 10 % of deaths were due to brain death. More than 40 % of brain-dead patients could donate organs. Patients who are unconscious after resuscitation from cardiac arrest, especially when resuscitated using e-CPR, should be carefully screened for signs of brain death. PMID- 27699458 TI - Long-term outcome of anterior cruciate ligament tear without reconstruction: a longitudinal prospective study. AB - PURPOSE: To analyse subjective and objective long-term outcomes of patients with anterior cruciate ligament (ACL)-deficient knees and limited demands regarding sportive activities. This subgroup of patients might be well-treated without ligament reconstruction. METHODS: We included 303 patients with unilateral tears of the ACL and conservative treatment into a prospective study. Mean age at injury was 33.8 (min. 18, max. 66) years. Follow-up was 27.1 (min. 21.3, max. 31.5) years. Follow-up examinations were conducted 12 and 27 years after injury. At the last follow-up we analysed 50 patients completely. To evaluate clinical and radiological outcomes we used the Lysholm score, Tegner activity scale, visual analogue scale for pain (VAS-pain), KOOS and Sherman score. RESULTS: Subjective outcome (Lysholm score and VAS-pain scale) improved between the 12th and 27th year after anterior cruciate ligament tear. At the same time activity level (Tegner activity scale) decreased. Also, arthritis (Sherman score) worsened over time. Twenty-seven years after injury, 90 % of the patients rated their ACL deficient knee as normal or almost normal; 10 % of the patients rated it as abnormal. The findings of this study show that there is a subgroup of patients with ACL tears who are well treated with physiotherapy alone, not reconstructing the ligament. Also, other authors found this correlation between activity level reduction and better subjective outcome. CONCLUSIONS: Conservative treatment of an ACL tear is a good treatment option for patients with limited demands regarding activity. Patient age, sportive activities and foremost subjective instability symptoms in daily life should be considered when deciding for or against ACL reconstruction. PMID- 27699459 TI - Description and reproducibility assessment of a new computerised tomography scan index to measure the glenoid orientation in relation to the anterior glenoid surface. AB - PURPOSE: To propose and to assess the reproducibility of a new method (GO [glenoid orientation] index) for the estimation of the glenoid orientation in relation to the anterior surface of the glenoid. METHODS: This is a retrospective study on computed tomography (CT) scan. The GO index was defined as the angle formed by a line perpendicular to the tangent to the anterior surface of the scapula and the glenoid line (which is defined as the line connecting the anterior and the posterior rim of the glenoid). The measurements were performed at the level of the glenoid where its diameter is the greatest. Two independent observers performed each measurement twice. The intra- and inter-observer reproducibility was evaluated by the Pearson coefficient (r) and the intra-class correlation coefficient (rho, ICC). The correlation between GO index and glenoid version as described by Friedman was also studied. RESULTS: Seventy-eight CT scans were analysed, 38 shoulders with glenohumeral arthritis and 40 healthy shoulders, 32 females/46 males, mean age 53.9 +/- 22.7 years. The measures were all highly correlated (r > 0.50, p = 0.00001). The intra- and inter-observer reproducibility was good to excellent (0.71 < rho < 0.84, p = 0.00001). GO index was 26.9 +/- 6.3 degrees , 28.4 +/- 6 degrees in the group with glenohumeral osteoarthritis and 25.5 +/- 6.4 degrees in the healthy group, p = 0.04. The glenoid version was -0.8 +/- 7.9 degrees in the group with glenohumeral osteoarthritis and -3.9 +/- 6 degrees in the healthy group, p = 0.05. No agreement was found between the glenoid version and GO index. CONCLUSIONS: GO index is simple and reproducible. It could be very useful for the pre-operative planning and intra-operative positioning of the implants in total shoulder arthroplasty. PMID- 27699460 TI - Anomalous branching pattern of the portal vein: right posterior portal vein originating from the left portal vein. AB - PURPOSE: To introduce a rare variant branching pattern of the portal vein with clinical relevance. METHODS: A 55-year-old man was examined by contrast-enhanced computed tomography to investigate the cause of fever and mildly elevated hepatic enzyme levels. RESULTS: Based on computed tomography, liver abscesses were identified which may have caused the fever and elevated hepatic enzyme levels. And a variation in the branching pattern of the portal vein was also detected in this patient, which has not been reported previously; the right posterior portal vein originated from the end of the horizontal part of the left portal vein. Identification of this rare branching pattern of the portal vein prior to hepatectomy, liver transplantation, and portal vein embolization is considered important to prevent complications. CONCLUSIONS: A rare variant in which the right posterior portal vein originated from the left portal vein was identified. Recognition of this variant may be important prior to surgical or interventional radiological strategies. PMID- 27699462 TI - Barbed Sutures in Body-Contouring: Outcome Analysis of 695 Procedures in 623 Patients and Technical Advances. AB - INTRODUCTION: Surgical wound closure is often complicated by suture-related issues. The recent introduction of knotless barbed sutures may address the shortcomings of conventional sutures and offer the additional benefit of reduced operating time. In this paper, we describe our experience with barbed sutures for body-contouring procedures. We share technical insights and evaluate postoperative complications. PATIENTS AND METHODS: A retrospective assessment of prospectively collected data over a period of more than 5 years was undertaken. Six hundred twenty-three consecutive patients underwent 695 body-contouring procedures with barbed suture closure. Patients were followed for at least 12 weeks postoperatively. Patient demographics, operation time as well as suture related complications, such as wound dehiscence and wound site infection were recorded and analyzed. RESULTS: Barbed sutures can facilitate skin closure, rectus plication, quilting, and deep layer closure in body-contouring procedures. The average operating time in our study cohort was 108 min with reduction mammoplasty being the quickest (94 min) and bodylift (156 min) being the slowest procedure. Sixty-eight patients experienced suture-related complications resulting in an overall complication rate of 9.7 % with thigh lift having the most (15 %) and reduction mammoplasty (7 %) the fewest adverse events. CONCLUSION: The use of barbed sutures allows quick closure of lengthy body contouring incision lines with low complication rates. Our observations support that barbed sutures are safe, convenient and effective. In our hands barbed sutures appear to be superior to traditional wound-closure techniques in body contouring procedures.

PMID- 27699461 TI - The Use of Integra Dermal Regeneration Template Versus Flaps for Reconstruction of Full-Thickness Scalp Defects Involving the Calvaria: A Cost-Benefit Analysis. AB - BACKGROUND: INTEGRA(r) Dermal Regeneration Template is a well-known and widely used acellular dermal matrix. Although it helps to solve many challenging problems in reconstructive surgery, the product cost may make it an expensive alternative compared to other reconstruction procedures. This retrospective study aims at comparing INTEGRA-based treatment to flap surgery in terms of cost and benefit. PATIENTS AND METHODS: We considered only patients treated for scalp defects with bone exposure in order to obtain two groups as homogeneous as possible. We identified two groups of patients: 17 patients treated with INTEGRA and 18 patients treated with flaps. All patients were admitted in our institution between 2004 and 2010, and presented a defect of the scalp following trauma or surgery for cancer, causing a loss of the soft tissues of the scalp with bone exposure without pericranium. To calculate the cost in constant euros of each treatment, three parameters were evaluated for each patient: cost of the surgical procedure (number of doctors and nurses involved, surgery duration, anesthesia, material used for surgery), hospitalization cost (hospitalization duration, dressings, drugs, topical agents), and outpatient cost (number of dressing changes, personnel cost, dressings type, anti-infective agents). The statistical test used in this study was the Wilcoxon Mann-Whitney (alpha = 0.05). RESULTS: No significant difference was characterized between the two groups for gender, age, presence of diabetes, mean defect size, and number of surgical procedures. All patients healed with good quality and durable closure. The median total cost per patient was ?11,121 (interquartile range (IQR) 8327-15,571) for the INTEGRA group and ?7259 (IQR 1852-24,443) for the flap group (p = 0.34). A subgroup of patients (six patients in the INTEGRA group and five patients in the flap group) showing defects larger than 100 cm2 were considered in a second analysis. Median total cost was ?11,825 (IQR 10,695-15,751) for the INTEGRA group and ?23,244 (IQR 17,348-26,942) for the flap group. CONCLUSION: Both treatments led to a good healing of the lesions with formation of soft and resistant tissue. No significant difference was characterized between the two groups for days of hospitalization and costs. In cases of patients with defects larger than 100 cm2 for whom major surgery is needed, the treatment with INTEGRA seemed to be less expensive than the treatment with free flaps or pedicle flaps.

PMID- 27699464 TI - Evaluation of LD decay and various LD-decay estimators in simulated and SNP-array data of tetraploid potato. AB - KEY MESSAGE: The number of SNPs required for QTL discovery is justified by the distance at which linkage disequilibrium has decayed. Simulations and real potato SNP data showed how to estimate and interpret LD decay. The magnitude of linkage disequilibrium (LD) and its decay with genetic distance determine the resolution of association mapping, and are useful for assessing the desired numbers of SNPs on arrays. To study LD and LD decay in tetraploid potato, we simulated autotetraploid genotypes and used it to explore the dependence on: (1) the number of haplotypes in the population (the amount of genetic variation) and (2) the percentage of haplotype specific SNPs (hs-SNPs). Several estimators for short range LD were explored, such as the average r 2, median r 2, and other percentiles of r 2 (80, 90, and 95 %). For LD decay, we looked at LD1/2,90, the distance at which the short-range LD is halved when using the 90 % percentile of r 2 at short range, as estimator for LD. Simulations showed that the performance of various estimators for LD decay strongly depended on the number of haplotypes, although the real value of LD decay was not influenced very much by this number. The estimator LD1/2,90 was chosen to evaluate LD decay in 537 tetraploid varieties. LD1/2,90 values were 1.5 Mb for varieties released before 1945 and 0.6 Mb in varieties released after 2005. LD1/2,90 values within three different subpopulations ranged from 0.7 to 0.9 Mb. LD1/2,90 was 2.5 Mb for introgressed regions, indicating large haplotype blocks. In pericentromeric heterochromatin, LD decay was negligible. This study demonstrates that several related factors influencing LD decay could be disentangled, that no universal approach can be suggested, and that the estimation of LD decay has to be performed with great care and knowledge of the sampled material. PMID- 27699465 TI - Vascular comorbidities in multiple sclerosis: a nationwide study from Denmark. AB - To investigate the occurrence of vascular comorbidities before and after the clinical onset of multiple sclerosis. In this combined case-control and cohort study, all Danish born citizens with onset of multiple sclerosis 1980-2005 were identified from the Danish Multiple Sclerosis Registry and randomly matched with controls regarding year of birth, gender, and municipality on January 1st in the year of multiple sclerosis (MS) onset (index date). Individual-level information on comorbidities was obtained from several independent nationwide registries and linked to the study population by unique personal identification numbers. To assess the presence of vascular comorbidities before and after MS onset, cases and controls were followed from January 1977 to the index date, and from the index date through December 2012. We used logistic regression to calculate odds ratios (ORs) and Cox regression to calculate hazard ratios (HRs). Before the index date, MS cases had a decreased probability for cerebrovascular comorbidity [OR 0.69 (95 % CI 0.48-0.99, p = 0.043)], and a numerically but not statistically significant decreased probability for cardiovascular comorbidity [OR 0.87 (95 % CI 0.71-1.07, p = 0.188)]. After the index date, MS cases had an increased risk for cerebrovascular comorbidity [HR 1.84 (95 % CI 1.69-2.00, p < 0.0005)], and for cardiovascular comorbidity [HR 1.08 (95 % CI 1.02-1.15, p = 0.013)]. The lower occurrence of cerebrovascular comorbidities in cases prior to MS onset could be due to protective immune mechanisms, while the higher occurrence of vascular comorbidities in cases after MS onset could be because of converging causal pathways of the coexisting diseases. These findings deserve to be studied closer in a broader spectrum of comorbidities in MS. PMID- 27699466 TI - An early case of a natural barrier to axonal degeneration.

PMID- 27699468 TI - Concomitant low back pain impairs outcomes after primary total knee arthroplasty in patients over 65 years: a prospective, matched cohort study. AB - INTRODUCTION: Knee osteoarthritis and low back pain (LBP) are two conditions with relatively high prevalence in patients over 65 years. The objective was to determine the effect of symptomatic LBP on the patient-reported outcome after primary TKA. MATERIAL AND METHOD: A cohort of 48 patients with concomitant LBP was prospectively matched 1:2 with patients without LBP for gender, age, body mass index and preoperative knee function. LBP severity was measured with the Oswestry Disability Index (ODI). Patient-reported outcomes were assessed with reduced Short-Form (SF12), Western Ontario and McMaster Universities score (WOMAC), and visual analogue scale (VAS) for satisfaction. Functional outcome was assessed with the Knee Society Scores (KSS). RESULTS: The mean postoperative follow-up was 3.2 years. At last follow-up, LBP cohort had significantly worse SF12, WOMAC, KSS and VAS scores than those patients without LBP. Preoperative ODI score was significantly correlated with outcomes. CONCLUSION: Worse functional and patient-reported outcomes were obtained in patients over 65 years with concomitant LBP, and this was related to the intensity of preoperative LBP. Despite successful outcome in the knee, the LBP usually remains after TKA and this may impair satisfaction and patient-reported outcomes. These patients should be properly informed about their potential outcomes. PMID- 27699471 TI - Histopathological evaluation and long-term results of soft tissue preservation technique in cholesteatoma surgery. AB - The goal of cholesteatoma surgery is total removal of the cholesteatoma matrix and prevention of recurrence. Preservation of soft tissue in the attic is reported to improve post-operative middle ear aeration, and thus prevents recurrence. However, the histology and nature of the preserved tissue have rarely been reported. The aim of this study is to clarify the histology of the preserved soft tissue in cholesteatoma surgery, and to show its relationship to the clinical course. Surgical specimens were obtained from ten patients with pars flaccida-type cholesteatoma. In these patients, cholesteatoma occupied the attic and the mastoid cavity. The cholesteatoma was removed so as not to expose the bone in the attic. After the removal of the lesions, soft tissue was harvested from the floor of the attic, using cupped forceps. The specimens were fixed with 10 % formalin, and stained with hematoxylin-eosin. The patients were followed-up for 8 years after the surgery. No patients showed post-operative inner ear disturbance or facial nerve palsy. In one patient, residual lesion was found during the revision surgery. The area of residual lesion was not explored during the first operation. Two other patients showed recurrent cholesteatoma in the pars tensa; one of these patients had accompanying otorrhea. The other seven patients showed no residual or recurrent cholesteatoma 8 years after the surgery. The histological examination showed that the harvested tissue was mainly composed of collagen fiber and fibroblasts. Ciliary epithelial cells were found in one patient. In three patients, cysts of mucosal remnants (glandular cysts), were embedded in the connective tissue. Two of these three patients experienced recurrent cholesteatoma, while the other seven patients were without recurrence at follow-up. Preservation of soft tissue behind the cholesteatoma matrix is a safe technique if the surgical field is fully visible. In most cases, the preserved tissue was fibrous connective tissue and lacked the characteristics of mucosa. The glandular cysts in the preserved soft tissue seem to be related to the recurrence of cholesteatoma. PMID- 27699472 TI - Cavernous hemangioma: a term to be canceled. PMID- 27699470 TI - Ethanolgel sclerotherapy of venous malformations improves health-related quality of-life in adults and children - results of a prospective study. AB - OBJECTIVES: To assess the treatment-induced changes of health-related quality-of life (HRQoL) in patients with venous malformations (VM) who underwent ethanol gel sclerotherapy. METHODS: The prospective study in children and adults was approved by the local ethics committee. 31 patients (mean age 23.42 years, range 6.6 - 46.5; 26 female, 5 male) with VM were included. Patients' self-assessed HRQoL was measured before and after treatment using psychometrically validated questionnaires for adults and children. Differences were analysed with a paired t test. RESULTS: 58 sclerotherapy sessions were performed. The Physical Component Summary (PCS) at baseline was 43.69 and increased significantly (p = 0.01122) to 48.95 after treatment. The bodily pain (BP) scale increased significantly from 37.94 to 48.56 (p = 0.00002), the general health (GH) scale increased significantly from 46.69 to 52.17 (p = 0.00609). Baseline Physical Summary Score (PHS) in children increased significantly after treatment (p < 0.00001) from 25.25 to 45.89. The baseline Psychosocial Summary Score (PSS) in children was 51.08 and increased significantly (p = 0.00031) after treatment to 58.84. CONCLUSION: Paediatric and adult patients with VM suffer from bodily pain with overall reduced physical functioning. After sclerotherapy, these restrictions are successfully returning to normal levels with a positive effect on mental and psychosocial domains. KEY POINTS: * Sclerotherapy in venous malformation patients has an unknown effect on health-related quality-of-life * Prospective study showed improvements in bodily pain and general health in adults * Children and adults improved from treatment with ethanol gel * Sclerotherapy is an appropriate therapy. PMID- 27699473 TI - Efficient targeted multiallelic mutagenesis in tetraploid potato (Solanum tuberosum) by transient CRISPR-Cas9 expression in protoplasts. AB - KEY MESSAGE: Altered starch quality with full knockout of GBSS gene function in potato was achieved using CRISPR-Cas9 technology, through transient transfection and regeneration from isolated protoplasts. Site-directed mutagenesis (SDM) has shown great progress in introducing precisely targeted mutations. Engineered CRISPR-Cas9 has received increased focus compared to other SDM techniques, since the method is easily adapted to different targets. Here, we demonstrate that transient application of CRISPR-Cas9-mediated genome editing in protoplasts of tetraploid potato (Solanum tuberosum) yielded mutations in all four alleles in a single transfection, in up to 2 % of regenerated lines. Three different regions of the gene encoding granule-bound starch synthase (GBSS) were targeted under different experimental setups, resulting in mutations in at least one allele in 2 12 % of regenerated shoots, with multiple alleles mutated in up to 67 % of confirmed mutated lines. Most mutations resulted in small indels of 1-10 bp, but also vector DNA inserts of 34-236 bp were found in 10 % of analysed lines. No mutations were found in an allele diverging one bp from a used guide sequence, verifying similar results found in other plants that high homology between guide sequence and target region near the protospacer adjacent motif (PAM) site is essential. To meet the challenge of screening large numbers of lines, a PCR-based high-resolution fragment analysis method (HRFA) was used, enabling identification of multiple mutated alleles with a resolution limit of 1 bp. Full knockout of GBSS enzyme activity was confirmed in four-allele mutated lines by phenotypic studies of starch. One remaining wild-type (WT) allele was shown sufficient to maintain enough GBSS enzyme activity to produce significant amounts of amylose. PMID- 27699474 TI - Atlas of human diseases influenced by genetic variants with extreme allele frequency differences. AB - Genetic variants with extreme allele frequency differences (EAFD) may underlie some human health disparities across populations. To identify EAFD loci, we systematically analyzed and characterized 81 million genomic variants from 2504 unrelated individuals of 26 world populations (phase III of the 1000 Genomes Project). Our analyses revealed a total of 434 genes, 15 pathways, and 18 diseases and traits influenced by EAFD variants from five continental populations. They included known EAFD genes, such as LCT (lactose tolerance), SLC24A5 (skin pigmentation), and EDAR (hair morphology). We found many novel EAFD genes, including TBC1D2B (autophagy mediator), TRIM40 (gastrointestinal inflammatory regulator), KRT71, KRT75, KRT83, and KRTAP10-1 (hair and epithelial keratin synthesis), PIK3R3 (insulin receptor interaction), DARS (neurological disorders), and NACA2 (skin inflammatory response). Our results also showed four complex diseases significantly associated with EAFD loci, including asthma (adjusted enrichment P = 4 * 10-8), type I diabetes (P = 6 * 10-9), alcohol consumption (P = 0.0002), and attention deficit/hyperactivity disorder (P = 0.003). This study provides a comprehensive atlas of genes, pathways, and human diseases significantly influenced by EAFD variants. PMID- 27699477 TI - Comprehensive analysis of the cellulolytic system reveals its potential for deconstruction of lignocellulosic biomass in a novel Streptomyces sp. AB - The giant snail Achatina fulica is considered an invasive species in most territories in which it was introduced, due to its ability to process a large amount of lignocellulose as a consequence of the presence of a cellulolytic associated microflora. Streptomyces are well known as crucial agents in the decomposition of complex polymers in soil environments and also as cellulolytic symbionts commonly associated with herbivore insects. Here, we employed a combination of genomic and biochemical tools for a detailed evaluation of the cellulolytic potential of Streptomyces sp. I1.2, an aerobic bacterium isolated from the intestinal lumen of A. fulica in a screening for cellulolytic bacteria. Genomic analysis revealed that the ratio and diversity of CAZy domains and GH families coded by Streptomyces sp. I1.2 are comparable to those present in other highly cellulolytic bacteria. After growth on crystalline cellulose or sugarcane bagasse as sole carbon sources, the functionality of several genes encoding endoglucanases, cellobiohydrolases, xylanases, CBMs, and one beta-glucosidase were confirmed by the combination of enzymatic activity measurements, zymography, TLC, and cellulose-binding assays. The endoglucanases secreted by this isolate were stable at 50 degrees C and exhibited activity over a broad pH range between 4.0 and 8.0. The endoglucanases and cellobiohydrolases secreted by Streptomyces sp. I1.2 exhibited specific activities that were similar to the levels present in a commercial cellulase preparation from Trichoderma reesei, while I1.2 xylanase levels were even 350 % higher. The results presented here show that Streptomyces sp. I1.2 is promising for future biotechnological applications, since it is able to produce endoglucanases, cellobiohydrolases, and xylanases in appreciable amounts when grown on a low-cost residue such as sugarcane bagasse. PMID- 27699478 TI - Cone beam computed tomography and its image guidance technology during percutaneous nucleoplasty procedures at L5/S1 lumbar level. AB - OBJECTIVE: To demonstrate the feasibility of percutaneous nucleoplasty procedures at L5/S1 level using cone beam CT (CBCT) and its associated image guidance technology for the treatment of lumbar disc herniation (LDH). MATERIALS AND METHODS: We retrospectively reviewed 25 cases (20 men, 5 women) of LDH at L5/S1 levels. CBCT as guidance imaging was chosen after a first unsuccessful fluoroscopy attempt that was related to complex anatomy (n = 15), rapid pathological changes due to degenerative diseases (n = 7) or both (n = 3). Technical success, defined as correct needle positioning in the target LDH, and safety were evaluated; overall procedure time and radiation dose were registered. A visual analog scale (VAS) was used to evaluate pain and discomfort pre intervention after 1 week and 1, 3, and 6 months after the procedure. RESULTS: Technical success was 100 %; using CBCT as guidance imaging the needle was correctly positioned at the first attempt in 20 out of 25 patients. Neither major nor minor complications were registered during or after the procedure. The average procedure time was 11 min and 56 s (range, 9-15 min), whereas mean procedural radiation dose was 46.25 Gy.cm2 (range 38.10-52.84 Gy.cm2), and mean fluoroscopy time was 5 min 34 s (range 3 min 40 s to 6 min 55 s). The VAS pain score decreased significantly from 7.6 preoperatively to 3.9 at 1 week, 2.8 at 1 month, 2.1 at 3 months, and 1.6 at 6 months postoperatively. CONCLUSIONS: CBCT guided percutaneous nucleoplasty is a highly effective technique for LDH with acceptable procedure time and radiation dose. PMID- 27699476 TI - The Association Between Bone Mineral Density and Airflow Limitation in a Cohort of Fit Elderly Women. AB - PURPOSE: As studies examining the association between bone mineral density (BMD) and airflow limitation (AL) have produced conflicting results, the current one set out to analyze if and to what degree there are any correlations between these variables in a population of fit elderly women. METHODS: One hundred and twenty one non-smoking, fit and healthy women (age >= 65 years) underwent anthropometric assessment, laboratory testing (serum 25-hydroxy vitamin D, parathormone, and cytokine levels), pulmonary function testing (PFT), and dual-energy X-ray absorptiometry to evaluate BMD values of the lumbar and femoral regions. RESULTS: A significant positive association was found between FEV1/FVC ratio (Tiffeneau index), a sensitive index of AL, and lumbar and femoral BMD; a 10 % increase in the FEV1/FVC ratio resulted in a significant increase of 0.025 g/cm2 in the total hip (p = 0.05), 0.027 g/cm2 in the femoral neck (p = 0.02), 0.028 g/cm2 in the femoral trochanter (p = 0.01), and 0.047 g/cm2 in the lumbar (p = 0.03) BMDs. Binary logistic analyses demonstrated more than a threefold higher risk of low BMD values for the lowest FEV1/FVC quartile in the lumbar (OR 4.62, 95 % CI 1.48 14.40, p = 0.008), total hip (OR 4.09, 95 % CI 1.28-13.05, p = 0.02 for the second quartile), and femoral trochanter regions (OR 3.90, 95 % CI 1.25-12.20, p = 0.02 for the third quartile). CONCLUSIONS: AL was associated with a higher risk of reduced BMD in healthy, fit elderly women.

AB - OBJECTIVE: Unlike with anterior cruciate ligament injury, little is known about the prevalence of intra-articular pathology associated with isolated posterior cruciate ligament (PCL) injury in the knee. The objectives of this study were to characterize and identify the frequency of meniscal tears and osteochondral injuries in these patients, and to see if management might be affected. MATERIALS AND METHODS: Altogether, 48 knee MRI exams with isolated PCL tears were evaluated for the presence of: grade and location of PCL tear, meniscal tear, articular chondral lesion, bone bruise, and fracture. Comparisons between PCL tear grade and location, as well as mechanism of injury when known, with the presence of various intra-articular pathologies, were made using the chi-square or Fisher's exact test as appropriate. RESULTS: In all, 69 % of isolated PCL tears occur in the midsubstance, 27 % proximally. Meniscal tears were seen in 25 % of knees, involving all segments of both menisci, except for the anterior horn medial meniscus. Altogether, 23 % had focal cartilage lesions, usually affecting the central third medial femoral condyle and medial trochlea, while 12.5 % of knees had fractures, and 48 % demonstrated bone bruises, usually involving the central to anterior tibiofemoral joint. The presence of a fracture (p = 0.0123) and proximal location of PCL tear (p = 0.0016) were both associated with the hyperextension mechanism of injury. There were no statistically significant associations between PCL tear grade and presence of intra-articular abnormality. CONCLUSION: Potentially treatable meniscal tears and osteochondral injuries are relatively prevalent, and demonstrable on MRI in patients with isolated acute PCL injury of the knee. PMID- 27699475 TI - Tooth agenesis and orofacial clefting: genetic brothers in arms? AB - Tooth agenesis and orofacial clefts represent the most common developmental anomalies and their co-occurrence is often reported in patients as well in animal models. The aim of the present systematic review is to thoroughly investigate the current literature (PubMed, EMBASE) to identify the genes and genomic loci contributing to syndromic or non-syndromic co-occurrence of tooth agenesis and orofacial clefts, to gain insight into the molecular mechanisms underlying their dual involvement in the development of teeth and facial primordia. Altogether, 84 articles including phenotype and genotype description provided 9 genomic loci and 26 gene candidates underlying the co-occurrence of the two congenital defects: MSX1, PAX9, IRF6, TP63, KMT2D, KDM6A, SATB2, TBX22, TGFalpha, TGFbeta3, TGFbetaR1, TGFbetaR2, FGF8, FGFR1, KISS1R, WNT3, WNT5A, CDH1, CHD7, AXIN2, TWIST1, BCOR, OFD1, PTCH1, PITX2, and PVRL1. The molecular pathways, cellular functions, tissue-specific expression and disease association were investigated using publicly accessible databases (EntrezGene, UniProt, OMIM). The Gene Ontology terms of the biological processes mediated by the candidate genes were used to cluster them using the GOTermMapper (Lewis-Sigler Institute, Princeton University), speculating on six super-clusters: (a) anatomical development, (b) cell division, growth and motility, (c) cell metabolism and catabolism, (d) cell transport, (e) cell structure organization and (f) organ/system-specific processes. This review aims to increase the knowledge on the mechanisms underlying the co-occurrence of tooth agenesis and orofacial clefts, to pave the way for improving targeted (prenatal) molecular diagnosis and finally to reflect on therapeutic or ultimately preventive strategies for these disabling conditions in the future. PMID- 27699481 TI - A kinetic model for flavonoid production in tea cell culture. AB - As one of the strategies for efficient production of a metabolite from cell cultures, a kinetic model is very useful tool to predict productivity under various culture conditions. In this study, we propose a kinetic model for flavonoid production in tea cell culture based on the cell life cycle and expression of PAL, the gene encoding phenylalanine ammonia-lyase (PAL)-the key enzyme in flavonoid biosynthesis. The flavonoid production rate was considered to be related to the amount of active PAL. Synthesis of PAL was modelled based on a general gene expression/translation mechanism, including the transcription of DNA encoding PAL into mRNA and the translation of PAL mRNA into the PAL protein. The transcription of DNA was assumed to be promoted at high light intensity and suppressed by a feedback regulatory mechanism at high flavonoid concentrations. In the model, mRNA and PAL were considered to self-decompose and to be lost by cell rupture. The model constants were estimated by fitting the experimental results obtained from tea cell cultures under various light intensities. The model accurately described the kinetic behaviors of dry and fresh cell concentrations, glucose concentration, cell viability, PAL specific activity, and flavonoid content under a wide range of light intensities. The model simulated flavonoid productivity per medium under various culture conditions. Therefore, this model will be useful to predict optimum culture conditions for maximum flavonoid productivity in cultured tea cells. PMID- 27699480 TI - Regional cerebellar volumetric correlates of manual motor and cognitive function. AB - Cerebellar volume declines with aging. Few studies have investigated age differences in regional cerebellar volume (RCV) and their association with motor and cognitive function. In 213 healthy older adults, we investigated the association of age with motor skills, cognition and RCV. Subsequently, we studied the association of RCV with motor skills and cognition. RCVs were derived from T1 weighted MRI scans using the automated SUIT segmentation method and clustered using principal component analysis (PCA). Motor skill (manual dexterity, tapping speed, bimanual visuomotor coordination, grip force) and cognition (mental rotation, verbal memory, inhibition, mental flexibility) were assessed. Behavioral measures were clustered into compounds using PCA: left hand motor skill, right hand motor skill, verbal memory and mental flexibility, and mental rotation & inhibition. Volume of the rostral middle frontal gyri (rMFG) and premotor areas (PMA) were related to performance for reference. Analyses were adjusted for age, sex, and education. Volume of the cerebellar anterior lobe and top of the superior posterior lobe were positively associated with motor skill. Volume of the bottom part of the posterior superior lobe and the inferior posterior lobe was positively associated with cognition. PMA volume was associated with cognition and motor skill and rMFG volume with motor skill. Although these results did not survive FDR correction, their effect sizes suggest that regional cerebellar volume selectively contributes to cognitive and motor skill. Effect sizes of cerebellar associations with performance were similar to those of rMFG/PMA and performance suggesting parallel contributions to performance. PMID- 27699482 TI - Anatomical influences on internally coupled ears in reptiles. AB - Many reptiles, and other vertebrates, have internally coupled ears in which a patent anatomical connection allows pressure waves generated by the displacement of one tympanic membrane to propagate (internally) through the head and, ultimately, influence the displacement of the contralateral tympanic membrane. The pattern of tympanic displacement caused by this internal coupling can give rise to novel sensory cues. The auditory mechanics of reptiles exhibit more anatomical variation than in any other vertebrate group. This variation includes structural features such as diverticula and septa, as well as coverings of the tympanic membrane. Many of these anatomical features would likely influence the functional significance of the internal coupling between the tympanic membranes. Several of the anatomical components of the reptilian internally coupled ear are under active motor control, suggesting that in some reptiles the auditory system may be more dynamic than previously recognized. PMID- 27699483 TI - ICE on the road to auditory sensitivity reduction and sound localization in the frog. AB - Frogs and toads are capable of producing calls at potentially damaging levels that exceed 110 dB SPL at 50 cm. Most frog species have internally coupled ears (ICE) in which the tympanic membranes (TyMs) communicate directly via the large, permanently open Eustachian tubes, resulting in an inherently directional asymmetrical pressure-difference receiver. One active mechanism for auditory sensitivity reduction involves the pressure increase during vocalization that distends the TyM, reducing its low-frequency airborne sound sensitivity. Moreover, if sounds generated by the vocal folds arrive at both surfaces of the TyM with nearly equal amplitudes and phases, the net motion of the eardrum would be greatly attenuated. Both of these processes appear to reduce the motion of the frog's TyM during vocalizations. The implications of ICE in amphibians with respect to sound localizations are discussed, and the particularly interesting case of frogs that use ultrasound for communication yet exhibit exquisitely small localization jump errors is brought to light. PMID- 27699484 TI - Running decreases knee intra-articular cytokine and cartilage oligomeric matrix concentrations: a pilot study. AB - INTRODUCTION: Regular exercise protects against degenerative joint disorders, yet the mechanisms that underlie these benefits are poorly understood. Chronic, low grade inflammation is widely implicated in the onset and progression of degenerative joint disease. PURPOSE: To examine the effect of running on knee intra-articular and circulating markers of inflammation and cartilage turnover in healthy men and women. METHODS: Six recreational runners completed a running (30 min) and control (unloaded for 30 min) session in a counterbalanced order. Synovial fluid (SF) and serum samples were taken before and after each session. Cytokine concentration was measured in SF and serum using a multiplexed cytokine magnetic bead array. Ground reaction forces were measured during the run. RESULTS: There were no changes in serum or SF cytokine concentration in the control condition. The cytokine GM-CSF decreased from 10.7 +/- 9.8 to 6.2 +/- 5.9 pg/ml pre- to post-run (p = 0.03). IL-15 showed a trend for decreasing concentration pre- (6.7 +/- 7.5 pg/ml) to post-run (4.3 +/- 2.7 pg/ml) (p = 0.06). Changes in IL-15 concentration negatively correlated with the mean number of foot strikes during the run (r 2 = 0.67; p = 0.047). The control condition induced a decrease in serum COMP and an increase in SF COMP, while conversely the run induced an increase in serum COMP and a decrease in SF COMP. Changes in serum and SF COMP pre- to post-intervention were inversely correlated (r 2 = 0.47; p = 0.01). CONCLUSIONS: Running appears to decrease knee intra-articular pro inflammatory cytokine concentration and facilitates the movement of COMP from the joint space to the serum. PMID- 27699485 TI - Passive and post-exercise cold-water immersion augments PGC-1alpha and VEGF expression in human skeletal muscle. AB - PURPOSE: We tested the hypothesis that both post-exercise and passive cold water immersion (CWI) increases PGC-1alpha and VEGF mRNA expression in human skeletal muscle. METHOD: Study 1 Nine males completed an intermittent running protocol (8 * 3-min bouts at 90 % [Formula: see text], interspersed with 3-min active recovery (1.5-min at 25 % and 1.5-min at 50 % [Formula: see text]) before undergoing CWI (10 min at 8 degrees C) or seated rest (CONT) in a counterbalanced, randomised manner. Study 2 Ten males underwent an identical CWI protocol under passive conditions. RESULTS: Study 1 PGC-1alpha mRNA increased in CONT (~3.4-fold; P < 0.001) and CWI (~5.9-fold; P < 0.001) at 3 h post-exercise with a greater increase observed in CWI (P < 0.001). VEGFtotal mRNA increased after CWI only (~2.4-fold) compared with CONT (~1.1-fold) at 3 h post-exercise (P < 0.01). Study 2 Following CWI, PGC-1alpha mRNA expression was significantly increased ~1.3-fold (P = 0.001) and 1.4-fold (P = 0.0004) at 3 and 6 h, respectively. Similarly, VEGF165 mRNA was significantly increased in CWI ~1.9 fold (P = 0.03) and 2.2-fold (P = 0.009) at 3 and 6 h post-immersion. CONCLUSIONS: Data confirm post-exercise CWI augments the acute exercise-induced expression of PGC-1alpha mRNA in human skeletal muscle compared to exercise per se. Additionally CWI per se mediates the activation of PGC-1alpha and VEGF mRNA expression in human skeletal muscle. Cold water may therefore enhance the adaptive response to acute exercise. PMID- 27699486 TI - Biofilm-associated infection: the hidden face of cerebrospinal fluid shunt malfunction. AB - Diagnosis of cerebrospinal fluid (CSF) shunt infection is difficult. Growing evidence links this pattern to biofilm-associated infections (BAI). Biofilm may explain the indolent development of the infection, and the poor efficiency of traditional microbiologic methods. We report the case of a patient admitted for hydrocephalus associated to CSF shunt malfunction. None of the clinical, serum, or CSF laboratory findings were in favor of an infectious process. Only scanning electron microscopy (SEM) revealed the presence of biofilm. Hence, despite a broad CSF shunt infection definition, some infections could remain undiagnosed by the traditional approach. This study is the first to provide some direct evidence for bacterial biofilm-associated CSF shunt infection. PMID- 27699488 TI - Late Somatic Gene 2 disrupts parental spheroids cooperatively with Volvox hatching enzyme A in Volvox. AB - MAIN CONCLUSION: We identified LSG2 as a novel lytic enzyme that accumulates in the parental extracellular matrix and disrupts parental spheroids cooperatively with VheA secreted by juveniles in Volvox. Spatiotemporally restricted degradation of extracellular matrix (ECM) is essential for development and survival in multicellular organisms. In an asexual life cycle of green algae Volvox, juveniles are released from parental spheroids through holes made by restricted degradation of parental ECM at the proper timing. Lytic enzyme(s) should specifically degrade parental ECM upon Volvox hatching, but little is known about the mechanisms of spatiotemporally restricted parental degradation. Here, we identified a glycoprotein encoded by the Late Somatic Gene 2 (LSG2) as a novel lytic enzyme that accumulates in parental ECM during the prehatching stages. The dual action of LSG2 and Volvox hatching enzyme A (VheA), a serine protease secreted by juveniles, causes the degradation of ECM sheets at all stages and destroys even daughter spheroids, while VheA alone disrupts spheroids only in the prehatching stage when LSG2 is accumulated, suggesting that the combination of LSG2 and VheA is sufficient to cause the degradation of ECM sheet. In the prehatching stage, parental spheroids became susceptible to the proteolysis by a mixture of bacterial proteases applied externally, which could be facilitated by LSG2. These results suggest that LSG2 disrupts parental ECM cooperatively with VheA by modifying the parental ECM to make it fragile, and that the appropriate activity of these enzymes is crucial for the parent-specific ECM degradation at the proper timing. PMID- 27699487 TI - Uncovering leaf rust responsive miRNAs in wheat (Triticum aestivum L.) using high throughput sequencing and prediction of their targets through degradome analysis. AB - MAIN CONCLUSION: Deep sequencing identified 497 conserved and 559 novel miRNAs in wheat, while degradome analysis revealed 701 targets genes. QRT-PCR demonstrated differential expression of miRNAs during stages of leaf rust progression. Bread wheat (Triticum aestivum L.) is an important cereal food crop feeding 30 % of the world population. Major threat to wheat production is the rust epidemics. This study was targeted towards identification and functional characterizations of micro(mi)RNAs and their target genes in wheat in response to leaf rust ingression. High-throughput sequencing was used for transcriptome-wide identification of miRNAs and their expression profiling in retort to leaf rust using mock and pathogen-inoculated resistant and susceptible near-isogenic wheat plants. A total of 1056 mature miRNAs were identified, of which 497 miRNAs were conserved and 559 miRNAs were novel. The pathogen-inoculated resistant plants manifested more miRNAs compared with the pathogen infected susceptible plants. The miRNA counts increased in susceptible isoline due to leaf rust, conversely, the counts decreased in the resistant isoline in response to pathogenesis illustrating precise spatial tuning of miRNAs during compatible and incompatible interaction. Stem-loop quantitative real-time PCR was used to profile 10 highly differentially expressed miRNAs obtained from high-throughput sequencing data. The spatio-temporal profiling validated the differential expression of miRNAs between the isolines as well as in retort to pathogen infection. Degradome analysis provided 701 predicted target genes associated with defense response, signal transduction, development, metabolism, and transcriptional regulation. The obtained results indicate that wheat isolines employ diverse arrays of miRNAs that modulate their target genes during compatible and incompatible interaction. Our findings contribute to increase knowledge on roles of microRNA in wheat-leaf rust interactions and could help in rust resistance breeding programs. PMID- 27699489 TI - Perioperative and short-term oncological outcomes of single-port surgery for transverse colon cancer. AB - PURPOSE: To compare the perioperative and short-term oncological outcomes of patients who underwent single-port surgery (SPS) with those of patients who underwent multi-port surgery (MPS) for transverse colon cancer. METHODS: The records of consecutive patients who underwent SPS (n = 75) or MPS (n = 41) for transverse colon cancer in our department between January, 2008 and December, 2015 were analyzed retrospectively. RESULTS: Operative times were significantly shorter in the SPS group than in the MPS group (185 vs. 195 min, respectively; P = 0.043). There were no significant differences in operative procedures, blood loss, or extent of lymph node dissection. The rate of postoperative complications was similar in both groups, but the length of hospital stay was significantly shorter in the single-port group than in the multi-port group (8 vs. 11 days, respectively; P < 0.001). Oncological outcomes were similar in both groups. The disease-free survival rate at 2 years did not differ significantly between the groups (91.1 vs. 94.9 %, respectively; P = 0.414). CONCLUSIONS: Our experience demonstrates that SPS is safe and can provide oncological outcomes equal to those of MPS for transverse colon cancer. PMID- 27699490 TI - Simplified comorbidity score for elderly patients undergoing thoracoscopic surgery for lung cancer. AB - PURPOSE: We investigated the efficiency of the Simplified Comorbidity Score (SCS) for predicting postoperative complications and prognosis in elderly patients undergoing video-assisted thoracoscopic surgery (VATS) for lung cancer. METHODS: We reviewed 216 patients aged 75 years or older, who underwent pulmonary resection by VATS for lung cancer between January, 2005 and December, 2012. The SCS assigns different scores to patients' comorbidities; namely, smoking (n = 7); diabetes mellitus (n = 5); renal insufficiency (n = 4); and respiratory, neoplastic, and cardiovascular comorbidities or alcoholism (n = 1 each). Patients were divided into a high SCS group (SCS >= 9; n = 154) and a low SCS group (<9; n = 62), for a comparative analysis of differences in perioperative factors and prognoses. RESULTS: Limited resection was more frequent in the high SCS group (58 %) than in the low SCS group (40 %; P = 0.02). Postoperative complications were more frequent in the high SCS group (45 %) than in the low SCS group (15 %; P < 0.01). A logistic regression analysis revealed that a high SCS was significantly predictive of postoperative complications (odds ratio 2.7; P = 0.02). The 5-year overall survival rate was 79 % for the low SCS group and 52 % for the high SCS group (P < 0.01). CONCLUSIONS: The SCS can predict the likelihood of postoperative complications and prognosis of elderly patients with VATS-treated lung cancers. PMID- 27699491 TI - Involvement of cell surface TG2 in the aggregation of K562 cells triggered by gluten. AB - Gluten-induced aggregation of K562 cells represents an in vitro model reproducing the early steps occurring in the small bowel of celiac patients exposed to gliadin. Despite the clear involvement of TG2 in the activation of the antigen presenting cells, it is not yet clear in which compartment it occurs. Herein we study the calcium-dependent aggregation of these cells, using either cell permeable or cell-impermeable TG2 inhibitors. Gluten induces efficient aggregation when calcium is absent in the extracellular environment, while TG2 inhibitors do not restore the full aggregating potential of gluten in the presence of calcium. These findings suggest that TG2 activity is not essential in the cellular aggregation mechanism. We demonstrate that gluten contacts the cells and provokes their aggregation through a mechanism involving the A-gliadin peptide 31-43. This peptide also activates the cell surface associated extracellular TG2 in the absence of calcium. Using a bioinformatics approach, we identify the possible docking sites of this peptide on the open and closed TG2 structures. Peptide docks with the closed TG2 structure near to the GTP/GDP site, by establishing molecular interactions with the same amino acids involved in stabilization of GTP binding. We suggest that it may occur through the displacement of GTP, switching the TG2 structure from the closed to the active open conformation. Furthermore, docking analysis shows peptide binding with the beta-sandwich domain of the closed TG2 structure, suggesting that this region could be responsible for the different aggregating effects of gluten shown in the presence or absence of calcium. We deduce from these data a possible mechanism of action by which gluten makes contact with the cell surface, which could have possible implications in the celiac disease onset. PMID- 27699493 TI - Chemotherapy for advanced gastric cancer: future perspective in Japan. AB - Differences in clinical outcomes between advanced gastric cancer (AGC) in Asia and that in other regions have been discussed for a long time, although no major significant differences in molecular profiles have been reported. The anti-human epidermal growth factor receptor 2 antibody trastuzumab and the anti-vascular endothelial growth factor receptor 2 monoclonal antibody ramucirumab were both approved as a treatment for AGC on the basis of global phase 3 trials including Japan. In recent years, others new agents for treatment of AGC have been investigated in global or Asian studies. Randomized phase 2 trials in Japan showed a higher response rate to S-1 plus leucovorin and oxaliplatin than to standard S-1 plus cisplatin, which is the rationale for an ongoing phase 3 trial in Asia (SOLAR trial). A recent global phase 1 trial of the anti-programmed cell death 1 monoclonal antibody pembrolizumab showed similar efficacy results in Asian patients and non-Asian patients, which led to large global phase 2 and phase 3 studies. Although the perspective of treatment of AGC in the near future depends on the results of ongoing large clinical trials, individualized choice of treatment based on more detailed molecular information will become important. PMID- 27699492 TI - The safety and effectiveness profile of eldecalcitol in a prospective, post marketing observational study in Japanese patients with osteoporosis: interim report. AB - This large-scale post-marketing surveillance study was conducted to assess the safety and effectiveness of eldecalcitol treatment in patients with osteoporosis in a Japanese clinical setting. A total of 3567 patients with osteoporosis were enrolled and received eldecalcitol 0.75 MUg/day for 12 months. For this interim report, 3285 patients were eligible for analysis. Mean age was 74.9 +/- 8.7 years; 86.8 % (2854/3285) were women. There were 142 reported adverse drug reactions (ADRs) in 129 patients (3.92 % of the total 3285 patients): the most common were hypercalcemia and increased blood calcium (0.88 %), renal impairment (0.27 %), abdominal discomfort (0.24 %), constipation (0.24 %), and pruritus (0.24 %). The incidence of ADRs was 5.10 % in men and 3.74 % in women. Although 10 serious ADRs were reported in 9 patients (0.27 %), no clinically significant safety issues were identified. Incidence of hypercalcemia or increased blood calcium was 8.47 % in patients with renal impairment and only 0.74 % in patients without renal impairment. At last observation, the incidence of new vertebral and nonvertebral fractures was 2.44 % and 1.70 %, respectively. There was a significant increase in bone mineral density at the lumbar spine and distal radius. The bone turnover markers BAP, serum NTX, urinary NTX, and TRACP-5b were suppressed by eldecalcitol treatment in both sexes. In conclusion, consistent with the findings of the phase III pivotal clinical trial, eldecalcitol was shown to have a favorable safety profile and effectiveness in Japanese patients with osteoporosis. However, periodic measurements of serum calcium were required to prevent occurrence of hypercalcemia during eldecalcitol treatment, especially in patients with renal impairment. PMID- 27699494 TI - Survival and clinical results of a modified "crosse de hockey" procedure for chronic isolated patellofemoral joint osteoarthritis: mid-term follow-up. AB - BACKGROUND: The optimum treatment for isolated patellofemoral joint osteoarthritis (PFJ-OA) remains controversial. The aim of this study was to assess the mid-term clinical results of a modified crosse de hockey procedure for the treatment of isolated PFJ-OA. MATERIALS AND METHODS: We assessed 37 knees in 31 patients treated by a modified crosse de hockey procedure. The mean age was 57.6 years (range, 46-75 years) and mean follow-up was 90.1 months (range, 24-216 months). We evaluated clinical and radiographic outcomes, as well as complication rates at the mid-term follow-up. RESULTS: The Kujala score (mean improvement of 46.7, P < 0.001) and the Fulkerson score (mean improvement of 19, P = 0.001) were significantly higher compared to preoperative values. Overall clinical results rated excellent in 24.3 %, very good in 21.6 %, good in 35.1 %, fair in 13.5 %, and poor in 5.4 % of knees. Patellar tilting (P = 0.015) and congruence angle (P = 0.018) significantly improved postoperatively. On the other hand, the Insall Salvati index decreased at the time of follow-up, although it remained in the physiologic range. Postoperatively, consecutive disease progression in the tibiofemoral joint and patellofemoral joint osteoarthritis were 18.9 and 5.4 %, respectively. The operative complication rate was 5.4 % in this case series. These percentages were lower than those of alternative tibial tuberosity osteotomy techniques. CONCLUSION: In most patients with chronic isolated PFJ-OA, tibial tuberosity osteotomy by modified crosse de hockey is a reliable procedure that provides good/excellent mid-term clinical results. LEVEL OF EVIDENCE: Level IV. PMID- 27699495 TI - Hubble trial: time to stick to basics for treatment of haemorrhoids? AB - The results of the Hubble trial, a randomised controlled trial comparing haemorrhoidal artery ligation with rubber band ligation for early-grade prolapsing haemorrhoids, are discussed. The difficulties in defining treatment success are debated along with the trial design highlighting the pitfalls of previous research. A finding that haemorrhoidal artery ligation is not necessarily superior to cheap alternatives has implications for current practice and future commissioning of surgeons. PMID- 27699496 TI - Incidence and surgical treatment of synthetic mesh-related infectious complications after laparoscopic ventral rectopexy. AB - BACKGROUND: Prosthetic-related infection and erosion occurring after a laparoscopic ventral rectopexy (LVR) are rare complications, and their importance is often underestimated. The aim of this study was to compare the incidence rate and surgical management of these complications in LVR patients with polyester (PE) or polypropylene (PP) prostheses. METHODS: From January 2004 to June 2012, 149 patients underwent LVR with PE and 176 underwent LVR with PP. Surgical management and rate of infectious and erosive prosthesis-related complications, depending on the type of prosthesis, were described and compared. Functional results after complications were assessed. RESULTS: Five patients from the PE prosthesis group (3.3 %), compared with two patients from the PP prosthesis group (1.1 %), experienced prosthesis-related infection or erosion (p = 0.16). The rate of erosion alone was 3.3 % in patients with a PE prosthesis, and 0.55 % in patients with a PP prosthesis (p = 0.06). The average time until clinical diagnosis of a prosthesis-related complication was identical for both groups: 31 months (range 3-62 months). All patients underwent surgical removal of the prosthesis: For the five patients from the PE group, complete removal was performed by laparoscopy associated with a transanal procedure. For the two patients in the PP mesh group, laparoscopy was ineffective in removing the mesh which was partially removed through a subsequent transanal procedure. None of the patients had a protective stoma, and in all patients the complication had resolved 12 months after removal. Only one patient had worsening functional symptoms (fecal incontinence) after prosthesis removal. CONCLUSIONS: When a prosthesis-related infection or erosion occurs, treatment consists in the surgical removal of the prosthesis by laparoscopy/and/or a transanal procedure. Functional symptoms do not routinely recur after prosthesis removal.

PMID- 27699498 TI - Thrombolysis in dementia patients with acute stroke: is it justified? AB - The administration of thrombolytic therapy in elderly patients with dementia and acute ischemic stroke may be controversial, because the reported risk of rt-PA associated intracerebral hemorrhage in these patients is higher compared with that of patients without dementia and because these patients are already disabled. Moreover, there are known risk factors for hemorrhagic transformation in patients with dementia: amyloid angiopathy, leukoaraiosis and the presence of microbleeds. In this review, we describe the impact of dementia on functional outcome following thrombolytic therapy for acute ischemic stroke and discuss some of the issues related to the use of this therapy in this specific patient's population. PMID- 27699499 TI - Influence of atmospheric states in semi-arid areas on hospital admission in cardio-surgical department. AB - The influence of the changes in atmospheric state, typical for areas close to big deserts, on acute myocardial infarction (AMI) was analyzed. Under test was the group of 3256 patients (77 % males, 23 % females), hospitalized in the Cardio Surgical Department of Soroka Medical Center at Ben-Gurion University (BGU, Israel) during 2000-2008. To explore the relationship between atmospheric parameters and AMI, multivariate regression analysis has been performed. AMI was most frequent in winter to spring and least in summer. The highest number of cases was recorded in December and the lowest in September. Hospital admissions showed a higher prevalence in men than in women; the ratio is 3.3/1.0. About 60 % of males were aged between 45 and 65 years old with maximum ~55 (21 %), whereas 60 % of women hospital admissions were aged between 65 and 80 years old with maximum ~72 (24 %). The result suggested that the monthly mean relative humidity at daytime and its overall daily differences, wind speed, and respirable fraction of particulate concentration are associated with the admission for AMI. The results of the study confirm the importance of atmospheric state variability for cardiovascular diseases. PMID- 27699501 TI - The glass is not yet half empty: agitation but not Varroa treatment causes cognitive bias in honey bees. AB - Honey bees (Apis mellifera) are prone to judge an ambiguous stimulus negatively if they had been agitated through shaking which simulates a predator attack. Such a cognitive bias has been suggested to reflect an internal emotional state analogous to humans who judge more pessimistically when they do not feel well. In order to test cognitive bias experimentally, an animal is conditioned to respond to two different stimuli, where one is punished while the other is rewarded. Subsequently a third, ambiguous stimulus is presented and it is measured whether the subject responds as if it expects a reward or a punishment. Generally, it is assumed that negative experiences lower future expectations, rendering the animals more pessimistic. Here we tested whether a most likely negatively experienced formic acid treatment against the parasitic mite Varroa destructor also affects future expectations of honey bees. We applied an olfactory learning paradigm (i.e., conditioned proboscis extension response) using two odorants and blends of these odorants as the ambiguous stimuli. Unlike agitating honey bees, exposure to formic acid did not significantly change the response to the ambiguous stimuli in comparison with untreated bees. Overall evidence suggests that the commonest treatment against one of the most harmful bee pests has no detrimental effects on cognitive bias in honey bees.

This process is mainly regulated by the hypoxia-inducible factors, HIF-1alpha and HIF-2alpha. Although endothelial cells do not form sprouts during prolonged hypoxic culturing, silencing of HIF-2alpha partially restores sprout formation. The present study identifies novel HIF-2alpha-target genes that may regulate endothelial sprouting during prolonged hypoxia. The gene expression profile of primary human microvascular endothelial cells (hMVECs) that were cultured at 20 % oxygen was compared to hMVECs that were cultured at 1 % oxygen for 14 days by using genome wide RNA-sequencing. The differentially regulated genes in hypoxia were compared to the genes that were differentially regulated upon silencing of HIF-2alpha in hypoxia. Surprisingly, KEGG pathway analysis showed that metabolic pathways were enriched within genes upregulated in response to hypoxia and enriched within genes downregulated upon HIF-2alpha silencing. Moreover, 51 HIF-2alpha-regulated genes were screened for their role in endothelial sprouting in hypoxia, of which four genes ARRDC3, MME, PPARG and RALGPS2 directly influenced endothelial sprouting during prolonged hypoxic culturing. The manipulation of specific downstream targets of HIF-2alpha provides a new, but to be further evaluated, perspective for restoring reduced neovascularization in several pathological conditions, such as diabetic ulcers or other chronic wounds, for improvement of vascularization of implanted tissue-engineered scaffolds.

AB - PURPOSE: The aim of this qualitative study was to gain a rich understanding of the impact that haematopoietic stem cell transplantation (HSCT) has on long-term survivor's quality of life (QoL). METHOD: Participants included 441 survivors who had undergone HSCT for a malignant or non-malignant disease. Data were obtained by a questionnaire positing a single open-ended question asking respondents to list the three issues of greatest importance to their QoL in survivorship. Responses were analysed and organised into QoL themes and subthemes. RESULTS: Major themes identified included the following: the failing body and diminished physical effectiveness, the changed mind, the loss of social connectedness, the loss of the functional self and the patient for life. Each of these themes manifests different ways in which HSCT survivor's world and opportunities had diminished compared to the unhindered and expansive life that they enjoyed prior to the onset of disease and subsequent HSCT. CONCLUSIONS: HSCT has a profound and pervasive impact on the life of survivors-reducing their horizons and shrinking various parts of their worlds. While HSCT survivors can describe the ways in which their life has changed, many of their fears, anxieties, regrets and concerns are existential in nature and are ill-defined-making it exceeding unlikely that they would be adequately captured by standard psychometric measures of QoL post HSCT.

AB - PURPOSE: Magnesium supplementation is an effective protective method against cisplatin-induced nephrotoxicity (CIN); however, there are few reports regarding the mechanism of its nephroprotective effect. The aim of this study was to determine whether premedication with intravenous magnesium prevents CIN and to determine the relationship between its nephroprotective effect and serum magnesium level. METHODS: Fifty-eight patients with head and neck cancer who received cisplatin, docetaxel, and 5-fluorouracil (DCF) were retrospectively investigated. Grade 2 or more serum creatinine elevation was defined as CIN. The incidence of CIN was compared between a magnesium sulfate (20 mEq, 2.46 g) premedication group and a non-magnesium group during the first cycle and in all cycles. RESULTS: CIN did not occur in any patients receiving magnesium premedication but did occur in 5 of 29 patients during the first cycle and in 6 patients during all subsequent cycles in patients who did not receive magnesium premedication. Furthermore, the variation of creatinine clearance was significantly worse in the non-magnesium group than in the magnesium premedication group from baseline. There was no difference in adverse effects or response rate between the two groups. Univariate analysis suggested that magnesium premedication significantly reduced the risk of CIN. On the other hand, serum magnesium depletion was seen in both groups to equal degrees despite supplementation. CONCLUSION: Intravenous magnesium premedication has a protective effect on cisplatin-induced nephrotoxicity without the influence on the serum magnesium level. Magnesium premedication is a simple nephroprotective method that does not influence other adverse effects or rate of response to chemotherapy.

Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is economically important with extensive breeding programs and seed trade. However, the molecular genetics of its seed development are largely unknown. We developed a transcriptome resource covering key developmental stages of megagametophytes over time: prefertilization, fertilization, embryogenesis, and early, unfertilized abortion. RNA sequencing reads were assembled de novo into 105,505 predicted high-confidence transcripts derived from 34,521 predicted genes. Expression levels were estimated based on alignment of the original reads to the reference. Megagametophytes express a distinct set of genes compared to those of vegetative tissues. Transcripts related to signaling, protein turnover, and RNA biogenesis have lower expression values in vegetative tissues, whereas cell wall remodeling, solute transport, and seed storage protein transcripts have higher expression values in megagametophytes. Seed storage protein transcripts become very abundant in both pollinated and unpollinated megagametophytes over time, even in aborting ovules. However, the absence of protein storage bodies in unfertilized megagametophytes suggests extensive posttranscriptional mechanisms that either inhibit storage protein translation or their aggregation into protein bodies. This novel transcriptome resource provides a foundation for further important insights into conifer seed development. PMID- 27699506 TI - Effect of Fluid Viscosity on the Cilia-Generated Flow on a Mouse Tracheal Lumen. AB - Mucous flow in a tracheal lumen is generated by the beat motion of ciliated cells to provide a clearance function by discharging harmful dust particles and viruses. Due to its physiological importance, the cilia-generated flow and the rheological properties of mucus have been investigated intensively. The effects of viscosity on the cilia-generated flow, however, have not been fully clarified. In this study, we measured bulk background velocity of ciliary flow using a micro particle tracking velocimetry method under various viscosity conditions in mice. The results showed that the flow velocity decreased as the increase with viscosity of ambient fluid. Moreover, no previous study has clarified the pump power generated by cilia, which provides important information with regard to understanding the molecular motor properties of cilia. Measurements of both the ciliary flow and the ciliary motion were conducted to determine the cilia pump power. Our results indicated that the cilia pump during the effective stroke did not drive the ciliary flow efficiently under high viscosity conditions; these findings are necessary to resolve the clearance function. PMID- 27699508 TI - A primer on the statistical modelling of learning curves in health professions education. AB - Learning curves are a useful way of representing the rate of learning over time. Features include an index of baseline performance (y-intercept), the efficiency of learning over time (slope parameter) and the maximal theoretical performance achievable (upper asymptote). Each of these parameters can be statistically modelled on an individual and group basis with the resulting estimates being useful to both learners and educators for feedback and educational quality improvement. In this primer, we review various descriptive and modelling techniques appropriate to learning curves including smoothing, regression modelling and application of the Thurstone model. Using an example dataset we demonstrate each technique as it specifically applies to learning curves and point out limitations.

PMID- 27699507 TI - Ex Vivo Methods for Informing Computational Models of the Mitral Valve. AB - Computational modeling of the mitral valve (MV) has potential applications for determining optimal MV repair techniques and risk of recurrent mitral regurgitation. Two key concerns for informing these models are (1) sensitivity of model performance to the accuracy of the input geometry, and, (2) acquisition of comprehensive data sets against which the simulation can be validated across clinically relevant geometries. Addressing the first concern, ex vivo micro computed tomography (microCT) was used to image MVs at high resolution (~40 micron voxel size). Because MVs distorted substantially during static imaging, glutaraldehyde fixation was used prior to microCT. After fixation, MV leaflet distortions were significantly smaller (p < 0.005), and detail of the chordal tree was appreciably greater. Addressing the second concern, a left heart simulator was designed to reproduce MV geometric perturbations seen in vivo in functional mitral regurgitation and after subsequent repair, and maintain compatibility with microCT. By permuting individual excised ovine MVs (n = 5) through each state (healthy, diseased and repaired), and imaging with microCT in each state, a comprehensive data set was produced. Using this data set, work is ongoing to construct and validate high-fidelity MV biomechanical models. These models will seek to link MV function across clinically relevant states. PMID- 27699511 TI - Genetic characterization of equine herpesvirus 1 isolates from abortion outbreaks in India. AB - Equine herpesvirus 1 (EHV1) is a common pathogen of horses that causes upper respiratory tract disease, abortion, neonatal death and neurological disease. The neurological form of disease is called equine herpesvirus myeloencephalopathy (EHM). During the past decade, the incidence of EHM has been on the rise in Europe, North America, Australia and Asia. Some EHV1 isolates causing EHM exhibit a single-nucleotide polymorphism (SNP) in the DNA polymerase gene (ORF30) at position 2254 (A2254 to G2254). Further, based on polymorphism in the ORF68, EHV1 isolates have been classified into different groups. The aim of the present study was to estimate the genetic diversity of EHV1 and to determine the prevalence of the neuropathogenic genotype of EHV1 in India. Out of 133 clinical specimens from abortion cases in northern India, 56 were positive for EHV1 infection. Analysis of the A/G SNP by real-time PCR and sequence analysis revealed that 54 of 56 samples (96.43 %) were of the non-neuropathogenic genotype (A2254), while two (3.57 %) had the neuropathogenic marker (G2254). Sequence analysis of the polymorphic region of ORF68 of EHV1 isolates (n = 9) from India indicated that the Delhi/1998, Tohana-2/2013, Hisar-2/2014 and Hisar-15/1990 isolates belonged to group 4, while the Jind/1996, Rajasthan/1998, Delhi-3/2007 and Tohana-5/1996 isolates clustered within group 5. One isolate (Hisar-7/1990) exhibited SNPs at positions C710 and C713, forming a separate group. Here, we report for the first time the detection of neuropathogenic genotypes of EHV1 in India and show that Indian EHV1 isolates cluster within groups 4 and 5. PMID- 27699510 TI - Plasma Level of Interleukin-35 as an Independent Prognostic Indicator in Hepatocellular Carcinoma. AB - BACKGROUND: Hepatocellular carcinoma is a major type of liver cancer with poor prognosis. AIM: The aim of the study was to determine the prognostic significance of plasma interleukin-35 level in hepatocellular carcinoma. METHODS: A total of 153 hepatocellular carcinoma patients and 153 healthy controls were enrolled. Blood samples were obtained at admission. Plasma interleukin-35 level was analyzed by enzyme-linked immunosorbent assay. Distribution of T cell subset and expression of Fas/FasL protein were detected by flow cytometry. The patients were followed up for 2 years. Poor prognosis was defined as death of hepatocellular carcinoma. RESULTS: The plasma levels of interleukin-35 were significantly higher in the patients than the controls (25.1 +/- 13.1, 9.3 +/- 6.3 pg/mL, P < 0.001). After adjusted for multiple confounding factors, the multivariate logistic regression analyses reported that high level of interleukin-35 (>=25.0 pg/mL) was associated with the poor prognosis in the patients (OR 6.63, 95 % CI 3.27-13.47). Compared with the patients with low level of interleukin-35 (<25.0 pg/mL), the patients with high level of interleukin-35 showed higher frequencies of CD4+CD25+FoxP3+ and CD3+Foxp3+ regulatory T cells (P < 0.001 and P < 0.001) and also showed higher apoptosis levels of CD8+ T cells (P < 0.001). CONCLUSION: Circulating interleukin-35 concentration might be an independent prognostic indicator in hepatocellular carcinoma. Such prognostic significance could be partly involved in the activation of regulatory T cell and the apoptosis of CD8+ T cell. PMID- 27699513 TI - Identification of internal poly(A) tracts (IPATs) of variable lengths in a novel tobacco rattle virus RNA2 in potatoes. AB - The nucleotide (nt) sequences of two closely related isolates (CeWF-2 and CeWGH 2) of a novel tobacco rattle virus (TRV) RNA2 were determined. The sequences of their RNA2-specific regions were almost identical and contained four open reading frames (ORFs) in an arrangement similar to that found in the previously described TRV TpO1 RNA2. Their predicted ORF 1 gene products shared 97 % amino acid sequence identity with the TpO1 coat protein, but the ORF 2 and ORF 3 gene products shared only 82 % sequence identity, and no appreciable sequence similarity was found between the CeWF-2/CeWGH-2 and TpO1 ORF 4 gene products. In the CeWGH-2 sequence, the RNA2-specific and RNA1-related regions were separated by seven adenine (A) residues. In CeWF-2, however, an internal poly(A) tract (IPAT) of variable size consisting of ca. 20 to 30 (A) residues was found. This is the first report of an IPAT occurring in a tobravirus RNA2. PMID- 27699512 TI - Synergistic effect of programmed cell death protein 1 blockade and secondary lymphoid tissue chemokine in the induction of anti-tumor immunity by a therapeutic cancer vaccine. AB - The use of DNA vaccines has become an attractive approach for generating antigen specific cytotoxic CD8+ T lymphocytes (CTLs), which can mediate protective antitumor immunity. The potency of DNA vaccines encoding weakly immunogenic tumor associated antigens (TAAs) can be improved by using an adjuvant injected together with checkpoint antibodies. In the current study, we evaluated whether the therapeutic effects of a DNA vaccine encoding human papilloma virus type 16 (HPV 16) E7 can be enhanced by combined application of an immune checkpoint blockade directed against the programmed death-1 (PD-1) pathway and secondary lymphoid tissue chemokine (SLC) also known as CCL21 adjuvant, in a mouse cervical cancer model. The therapeutic effects of the DNA vaccine in combination with CCL21 adjuvant plus PD-1 blockade was evaluated using a tumor growth curve. To further investigate the mechanism underlying the antitumor response, cytolytic and lymphocyte proliferation responses in splenocytes were measured using non radioactive cytotoxicity and MTT assays, respectively. Vascular endothelial growth factor (VEGF) and IL-10 expression in the tumor and the levels of IFN gamma and IL-4 in supernatants of spleno-lymphocyte cultures were measured using ELISA. The immune efficacy was evaluated by in vivo tumor regression assay. The results showed that vaccination with a DNA vaccine in combination with the CCL21 adjuvant plus PD-1 blockade greatly enhanced cytotoxic T lymphocyte production and lymphocyte proliferation rates and greatly inhibited tumor progression. Moreover, the vaccine in combination with adjuvant and blockade significantly reduced intratumoral VEGF, IL-10 and splenic IL-4 but induced the expression of splenic IFN-gamma. This formulation could be an effective candidate for a vaccine against cervical cancers and merits further investigation. PMID- 27699514 TI - Coffee consumption and risk of all-cause, cardiovascular, and cancer mortality in smokers and non-smokers: a dose-response meta-analysis. AB - Coffee consumption has been associated with several benefits toward human health. However, its association with mortality risk has yielded contrasting results, including a non-linear relation to all-cause and cardiovascular disease (CVD) mortality and no association with cancer mortality. As smoking habits may affect the association between coffee and health outcomes, the aim of the present study was to update the latest dose-response meta-analysis of prospective cohort studies on the association between coffee consumption and mortality risk and conduct stratified analyses by smoking status and other potential confounders. A systematic search was conducted in electronic databases to identify relevant studies, risk estimates were retrieved from the studies, and dose-response analysis was modeled by using restricted cubic splines. A total of 31 studies comprising 1610,543 individuals and 183,991 cases of all-cause, 34,574 of CVD, and 40,991 of cancer deaths were selected. Analysis showed decreased all-cause [relative risk (RR) = 0.86, 95 % confidence interval (CI) = 0.82, 0.89)] and CVD mortality risk (RR = 0.85, 95 % CI = 0.77, 0.93) for consumption of up to 4 cups/day of coffee, while higher intakes were associated with no further lower risk. When analyses were restricted only to non-smokers, a linear decreased risk of all-cause (RR = 0.94, 95 % CI = 0.93, 0.96), CVD (RR = 0.94, 95 % CI = 0.91, 0.97), and cancer mortality (RR = 0.98, 95 % CI = 0.96, 1.00) for 1 cup/day increase was found. The search for other potential confounders, including dose response analyses in subgroups by gender, geographical area, year of publication, and type of coffee, showed no relevant differences between strata. In conclusion, coffee consumption is associated with decreased risk of mortality from all-cause, CVD, and cancer; however, smoking modifies the observed risk when studying the role of coffee on human health. PMID- 27699515 TI - A 5-item frailty index based on NSQIP data correlates with outcomes following paraesophageal hernia repair. AB - BACKGROUND: Frailty is a measure of physiologic reserve associated with increased vulnerability to adverse outcomes following surgery in older adults. The 'accumulating deficits' model of frailty has been applied to the NSQIP database, and an 11-item modified frailty index (mFI) has been validated. We developed a condensed 5-item frailty index and used this to assess the relationship between frailty and outcomes in patients undergoing paraesophageal hernia (PEH) repair. METHODS: The NSQIP database was queried for ICD-9 and CPT codes associated with PEH repair. Subjects >=60 years who underwent PEH repair between 2011 and 2013 were included. Five of the 11 mFI items present in the NSQIP data on the most consistent basis were selected for the condensed index. Univariate and multivariate logistic regressions were used to determine the validity of the 5 item mFI as a predictor of postoperative mortality, complications, readmission, and non-routine discharge. RESULTS: A total of 3711 patients had data for all variables in the 5-item index, while 885 patients had complete data to calculate the 11-item mFI. After controlling for competing risk factors, including age, ASA score, wound classification, surgical approach, and procedure timing (emergent vs non-emergent), we found the 5-item mFI remained predictive of 30-day mortality and patients being discharged to a location other than home (p < 0.05). A weighted Kappa was calculated to assess agreement between the 5-item and 11-item mFI and was found to be 0.8709 (p < 0.001). CONCLUSIONS: Frailty, as assessed by the 5-item mFI, is a reasonable alternative to the 11-item mFI in patients undergoing PEH repair. Utilization of the 5-item mFI allows for a significantly increased sample size compared to the 11-item mFI. Further study is necessary to determine whether the condensed 5-item mFI is a valid measure to assess frailty for other types of surgery. PMID- 27699516 TI - Preoperative localization of colorectal cancer: a systematic review and meta analysis. AB - BACKGROUND: Preoperative colorectal tumor localization is crucial for appropriate resection and treatment planning. As the localization accuracy of conventional colonoscopy is considered to be low, several localization techniques have been developed. We systematically reviewed the tumor localization error rates of several preoperative endoscopic techniques and synthesized information on risk factors for localization errors and procedure-related adverse events. METHODS: MEDLINE, EMBASE, the Cochrane Library, and the grey literature were searched. Studies were included if they reported tumor localization errors in patients with colorectal cancer undergoing resection with curative intent. Using random-effects models, pooled incidence of tumor localization errors were derived for conventional colonoscopy and colonoscopic tattooing. Due to the lack of comparative studies, a direct comparison of the pooled estimates was performed. Procedure-related adverse events, risk factors for localization errors, and the localization outcomes of other techniques such as colonoscopic clip placement, radioguided occult colonic lesion identification, and the use of magnetic endoscope imaging were also synthesized. RESULTS: A total of 38 non-randomized controlled and observational studies were included in this review (2578 patients underwent conventional colonoscopy and 643 colonoscopic tattooing). The pooled incidence of localization errors with conventional colonoscopy was 15.4 % (95 % CI 12.0-18.7), whereas that of colonoscopic tattooing was 9.5 % (95 % CI 5.7 13.3), mean difference 5.9 % (95 % CI 0.65-11.14, p = 0.03). Adverse events secondary to tattooing were infrequent, and most were cases of ink spillage. Limited information was available for other localization techniques. CONCLUSION: Conventional colonoscopy has a higher incidence of localization error compared to colonoscopic tattooing for localization of colorectal cancer. Colonoscopic tattooing is safe and leads to fewer tumor localization errors. Given the widespread adoption of laparoscopic resections for colorectal cancer, routine colonoscopic tattooing should be adopted. However, studies directly comparing different localization techniques are needed. PMID- 27699517 TI - Modified overlap method using knotless barbed sutures (MOBS) for intracorporeal esophagojejunostomy after totally laparoscopic gastrectomy. AB - BACKGROUND: Compared to end-to-side anastomosis with a circular stapler, the overlap method is favored for intracorporeal esophagojejunostomy because it facilitates handling of the stapler, even in narrow spaces, and wider anastomosis. However, it associates with technical difficulties during anastomosis, including difficult traction on the esophageal stump that necessitates stay sutures. Here, we introduce a new modified overlap method that employs knotless barbed sutures (MOBS) and report the outcomes of our case series. METHOD: All consecutive patients who underwent intracorporeal esophagojejunostomy in 2015-2016 were included. All patients underwent surgery as follows: After esophageal transection with a linear stapler, two V-loc 90 sutures (Covidien, Mansfield, MA, USA) were sutured in the center of the stapled line. The opening was made between the two threads, and the intraluminal space was identified. The jejunum was ascended toward the esophageal stump by inserting a 45-mm-long linear staple. The anastomosis was made at the space between the right and left crura. After firing the linear stapler, the entry hole was closed bidirectionally using the pre-sutured threads. RESULTS: Forty patients underwent MOBS (27 by laparoscopy; 13 by robot). Mean total operative and MOBS procedural times were 180.6 and 22.4 min, respectively. Mean hospital stay was 6.9 days. Two patients had major complications (5.0 %). There were no anastomosis-related complications. Laparoscopy and robot subgroups did not differ in mean MOBS procedural times (22.2 vs. 22.7 min, p = 0.787). CONCLUSION: MOBS is a safe and feasible method that is a good option for intracorporeal esophagojejunostomy after laparoscopic gastrectomy. PMID- 27699518 TI - Long-term outcome of peroral endoscopic myotomy for esophageal achalasia in patients with previous Heller myotomy. AB - BACKGROUND: Peroral endoscopic myotomy (POEM) is an emerging procedure in the treatment of esophageal achalasia, a primary motility disorder. However, the long term outcome of POEM in patients, who have previously undergone a Heller myotomy, is unknown. METHODS: Using a local database, we identified patients with esophageal achalasia, who underwent POEM. We compared patients with a previous Heller myotomy to those, who had received none or only non-surgical therapy prior to the POEM procedure. We conducted follow-up examinations at 3, 12, and 24 months following the procedure. RESULTS: We included 66 consecutive patients undergoing POEM for achalasia, of which 14 (21.2 %) had undergone a prior Heller myotomy. In both groups, the preoperative Eckardt score was 7. Postoperatively, the non-Heller group experienced a more pronounced symptom relief at both 3-, 12 , and 24-month follow-up compared with the Heller group, and there was a tendency for the effect of POEM to reduce over time. We suggest that there is a correlation between preoperative measurements of gastroesophageal sphincter pressures and the chance of a successful POEM. CONCLUSIONS: POEM has a place in the treatment of esophageal achalasia in patients with a prior Heller myotomy and persistent symptoms as it is a safe procedure with acceptable long-term results. PMID- 27699519 TI - Genetic analysis of oriental fruit fly, Bactrocera dorsalis (Diptera: Tephritidae) populations based on mitochondrial cox1 and nad1 gene sequences from India and other Asian countries. AB - The study examined the genetic diversity and demographic history of Bactrocera dorsalis, a destructive and polyphagous insect pest of fruit crops in diverse geographic regions of India. 19 widely dispersed populations of the fly from India and other Asian countries were analysed using partial sequences of mitochondrial cytochrome oxidase I (cox1) and NADH dehydrogenase 1 (nad1) genes to investigate genetic diversity, genetic structure, and demographic history in the region. Genetic diversity indices [number of haplotypes (H), haloptype diversity (Hd), nucleotide diversity (pi) and average number of nucleotide difference (k)] of populations revealed that B. dorsalis maintains fairly high level of genetic diversity without isolation by distance among the geographic regions. Demographic analysis showed significant (negative) Tajimas' D and Fu's F S with non significant sum of squared deviations (SSD) values, which indicate the possibility of recent sudden expansion of species and is further supported through distinctively star-like distribution structure of haplotypes among populations. Thus, the results indicate that both ongoing and historical factors have played important role in determining the genetic structure and diversity of the species in India. Consequently, sterile insect technique (SIT) could be a possible management strategy of species in the regions. PMID- 27699520 TI - Online Radiology Reporting with Peer Review as a Learning and Feedback Tool in Radiology; Implementation, Validity, and Student Impressions. AB - Communicating radiological reports to peers has pedagogical value. Students may be uneasy with the process due to a lack of communication and peer review skills or to their failure to see value in the process. We describe a communication exercise with peer review in an undergraduate veterinary radiology course. The computer code used to manage the course and deliver images online is reported, and we provide links to the executable files. We tested to see if undergraduate peer review of radiological reports has validity and describe student impressions of the learning process. Peer review scores for student-generated radiological reports were compared to scores obtained in the summative multiple choice (MCQ) examination for the course. Student satisfaction was measured using a bespoke questionnaire. There was a weak positive correlation (Pearson correlation coefficient = 0.32, p < 0.01) between peer review scores students received and the student scores obtained in the MCQ examination. The difference in peer review scores received by students grouped according to their level of course performance (high vs. low) was statistically significant (p < 0.05). No correlation was found between peer review scores awarded by the students and the scores they obtained in the MCQ examination (Pearson correlation coefficient = 0.17, p = 0.14). In conclusion, we have created a realistic radiology imaging exercise with readily available software. The peer review scores are valid in that to a limited degree they reflect student future performance in an examination. Students valued the process of learning to communicate radiological findings but do not fully appreciated the value of peer review. PMID- 27699521 TI - Longitudinal change in choroidal thickness after trabeculectomy in primary open angle glaucoma patients. AB - PURPOSE: To investigate longitudinal changes in intraocular pressure (IOP), axial length (AL), and choroidal thickness (ChT) in primary open-angle glaucoma (POAG) eyes after trabeculectomy and to evaluate the parameters that might influence those changes. METHODS: In this prospective observational study, we recruited 28 patients with POAG (28 eyes) scheduled for trabeculectomy. The average macular ChTs and foveal retinal thicknesses along 6-mm segments centered on the fovea were examined preoperatively and postoperatively (at 1, 3, and 6 months) using swept-source optical coherence tomography. The IOP, AL, and mean deviation (MD) of standard automated perimetry (SAP) were also analyzed as independent variables. RESULTS: Results from 16 patients were included in the final analysis. A significant increase in ChT with respect to the preoperative value was observed at every postoperative stage (1 month, P < 0.001; 3 months, P < 0.001; 6 months, P = 0.011), whereas the retinal thickness showed no significant change over the study period. The ChT increase and IOP reduction were sustained throughout the 6 month period without further significant changes. Stepwise multivariate analyses showed significant correlations between the percentage decrease in IOP and the percentage increase in ChT at 1 and 6 months postoperatively. The percentage increase in ChT was also significantly correlated with a better MD of the SAP at 1 month (beta = 0.01; P = 0.009). CONCLUSIONS: The ChT increase following trabeculectomy was sustained at 1, 3, and 6 months postoperatively. The percentage increase in ChT was significantly correlated with the percentage change in IOP and (more weakly) with better SAP MD values. PMID- 27699522 TI - Eyelid cleansing with ointment for obstructive meibomian gland dysfunction. AB - PURPOSE: To investigate the efficacy of eyelid margin cleansing with ofloxacin ophthalmic ointment in obstructive meibomian gland dysfunction (MGD) patients. METHODS: Thirty-one eyes of 31 patients diagnosed with obstructive MGD were enrolled. All subjects were instructed to rub the eyelid edge with ofloxacin eye ointment once daily prior to bathing. Lid margin abnormalities, meibum properties, and tear stability were observed before and 3 months after ointment treatment. A questionnaire relating to the severity of MGD symptoms was administered after the treatment. RESULTS: Vascular engorgement, meibum, dandruff like debris, and fluorescein staining scores significantly decreased after the treatment, whereas tear break-up time significantly increased (p < 0.05). Symptoms related to MGD improved after the treatment in 86.2 % of cases. CONCLUSIONS: Cleansing treatment ofloxacin ophthalmic ointment at the eyelid margin may be effective for patients with obstructive MGD. PMID- 27699523 TI - Phenotypic variability of Dent disease in a large New Zealand kindred. AB - BACKGROUND: Dent disease 1 is a rare cause of chronic kidney disease (CKD) in childhood secondary to mutations in the gene encoding the chloride-proton exchanger, CLC-5, which is found mainly in the proximal tubule. Clinical manifestations are variable and there are no known genotype-phenotype correlations. CASE DIAGNOSIS/TREATMENT: The proband was identified as having a mutation in CLCN5. The extended family of the proband was invited to participate in a study of Dent disease after several males were noted to have a history of CKD. Urine retinol binding protein, urine calcium, serum creatinine, and DNA samples were collected for analysis. Ten hemizygous males and 6 heterozygous females were identified. Advanced CKD was detected in 3 males (1 child). Renal biopsies in 4 children showed both glomerular and tubulo-interstitial changes. There was no correlation between age and disease severity. CONCLUSIONS: This is the first reported family from the southern hemisphere with this condition. A novel CLCN5 mutation is described, c.1618G>C (p.Ala540Pro). The severity of renal disease varies greatly among individuals. PMID- 27699525 TI - Psychological Distress as an Indicator of Co-Occurring Psychopathology among Treatment-Seeking Disordered Gamblers. AB - Disordered gamblers frequently present with concurrent anxiety, depressive, personality, and substance use disorders, which may complicate treatment. Although there is a need for a thorough assessment, some questionnaires may prove lengthy for clients and clinicians. Thus, there is a need for brief screens for identifying co-occurring psychopathology. The present study sought to examine whether a brief, self-report measure of psychological distress could indicate the presence of co-occurring psychopathology among an outpatient sample of disordered gamblers. At intake, 69 participants completed self-report measures of distress and gambling symptomatology, a personality inventory, and a structured interview for the diagnostic criteria for disordered gambling. Gamblers with greater elevations of psychological distress evidenced greater severity of gambling pathology. Clinically significant elevations were present for symptoms of depression, deviancy, and anxiety, but not substance abuse. Greater scores of psychological distress significantly predicted elevations of depression, deviancy, and anxiety. Sensitivity and specificity were evaluated and the findings supported that an average psychological distress score of 16 corresponded with the presence of co-occurring psychopathology. Clinicians treating disordered gamblers should consider screening for co-occurring psychopathology with brief, self-report measures of psychological distress. PMID- 27699524 TI - Solid state NMR of isotope labelled murine fur: a powerful tool to study atomic level keratin structure and treatment effects. AB - We have prepared mouse fur extensively 13C,15N-labelled in all amino acid types enabling application of 2D solid state NMR techniques which establish covalent and spatial proximities within, and in favorable cases between, residues. 13C double quantum-single quantum correlation and proton driven spin diffusion techniques are particularly useful for resolving certain amino acid types. Unlike 1D experiments on isotopically normal material, the 2D methods allow the chemical shifts of entire spin systems of numerous residue types to be determined, particularly those with one or more distinctively shifted atoms such as Gly, Ser, Thr, Tyr, Phe, Val, Leu, Ile and Pro. Also the partial resolution of the amide signals into two signal envelopes comprising of alpha-helical, and beta sheet/random coil components, enables resolution of otherwise overlapped alpha carbon signals into two distinct cross peak families corresponding to these respective secondary structural regions. The increase in resolution conferred by extensive labelling offers new opportunities to study the chemical fate and structural environments of specific atom and amino acid types under the influence of commercial processes, and therapeutic or cosmetic treatments. PMID- 27699527 TI - Epidemiology of HPV-Positive Tumors in Europe and in the World. AB - Strong evidence has accumulated in the last 15 years showing that infection by certain human papillomaviruses (HPVs) is etiologically involved in a subset of head and neck cancers (HNCs). In this chapter, epidemiologic-related topics on HNCs are reviewed: (i) HPV-attributable fractions and HPV-type distributions by different anatomical HNC sites, using not only HPV DNA but other more specific markers of causality; (ii) an update of the HPV-related HNCs burden worldwide and by regions; and finally, (iii) the determinants for HPV positivity in HNCs, focussing on gender, age, smoking habits, sexual behavior, and other related factors such as tonsillectomy performance. This information is essential in order to understand the burden of the disease and its dynamics and changing patterns, as well as for planning and assessment of the potential impact of HPV-based preventive strategies for HNCs. PMID- 27699526 TI - HPV in Head and Neck Cancer-30 Years of History. AB - The interesting history of papillomavirus (PV) research has been reviewed before. The history of human papillomavirus (HPV) in head and neck region starts in 1901 when the contagious transmission of warty lesions into the mouth via oral sex was described, although the confirmation of their viral etiology had to wait until 1907. Ullman was the first to associate the human wart virus with laryngeal warts. Parsons and Kidd described the natural history of oral PV infections in rabbits already in 1942, but these findings were corroborated in humans only recently. Koilocytotic atypia described by Koss and Durfee in 1956 was recognized as a sign of HPV infection in cervical precancer lesions only in 1976-1977 (Meisels and Fortin; Purola and Savia). This prompted systematic surveys of head and neck lesions for the detection of koilocytosis since the late 1970s, and the authors of this communication were the first to propose the HPV involvement in a subgroup of head and neck cancers. Brandsma and Abramson demonstrated HPV16 DNA in tonsillar SCCs in 1989. Since the early 2000s, HPV research of head and neck squamous cell carcinomas (HNSCC) has made impressive progress, confirming that the specific anatomic site plays a key role in determining the susceptibility to HPV infection. The most likely cancer sites associated with HPV are the base of the tongue and palatine tonsils, followed by oral cavity, larynx, and sinonasal mucosa. There is substantial geographic variation in HPV association with HNSCC. Patients with HPV-associated HNSCC are younger, and survival is better than in the absence of HPV. PMID- 27699528 TI - Molecular Patterns and Biology of HPV-Associated HNSCC. AB - Head and neck cancer is the sixth most common cancer worldwide. The large majority are squamous cell carcinomas (HNSCC) that develop in the mucosal linings of the upper aerodigestive tract. These tumors develop either by exogenous carcinogen exposure (smoking, alcohol drinking) or by human papillomavirus (HPV) infection, particularly those in the oropharynx (OPSCC). HPV-positive (HPV+ve) and HPV-negative (HPV-ve) OPSCC are considered different disease entities. HPV+ve tumors are different at the molecular level and likely as a consequence have a much more favorable prognosis than HPV-ve tumors, despite their generally advanced stage at presentation. In general, HNSCCs develop in precancerous mucosal changes, and the apparent lack of precancerous HPV+ve mucosal changes is therefore remarkable. In this Chapter, head and neck carcinogenesis is discussed and the molecular differences between HPV+ve and HPV-ve tumors are outlined. PMID- 27699529 TI - HPV Integration in Head and Neck Squamous Cell Carcinomas: Cause and Consequence. AB - Human papillomaviruses (HPVs) are a necessary cause of anogenital squamous cell carcinomas (SCC) and a subgroup of head and neck SCC, i.e., those originating in the oropharynx. The key events in high-risk HPV (HRHPV)-associated neoplastic progression include persistent infection, deregulated expression of virus early genes in basal epithelial cells, local immune suppression and the accumulation of chromosomal alterations. Evidence for these events particularly comes from studies of uterine cervical carcinogenesis; primary premalignant HRHPV-positive lesions of the head and neck mucosa are seldomly detected. Integration of virus DNA into host chromosomes is considered an important driver of carcinogenesis and observed in 40 up to 90 % of uterine cervical SCC (UCSCC) and oropharyngeal SCC (OPSCC), dependent on the integration detection method used and HRHPV type. In OPSCC, > 90 % HPV-positive tumors are infected with HPV16. Ten up to 60 % of HPV positive tumors thus contain extrachromosomal (episomal) virus. In this chapter, causes and consequences of HPV integration are summarized from the literature, with special focus on the site of HPV integration in the cellular genome, and its effect on expression of viral oncogenes (particularly E6 and E7), on human (tumor) gene expression and on deregulation of cell proliferation, apoptosis and cell signaling pathways. Also data on DNA methylation, viral load and clinical outcome in relation to HPV integration are provided. PMID- 27699530 TI - Risk Factors for Oral Infection with Human Papillomavirus. AB - Human papillomavirus has been identified as a causative factor for a subset of head and neck carcinomas (HNSCC). The majority of the HPV-positive tumors arises in the oropharyngeal region, and at present, the infection of the human papilloma type 16 is the major cause of the oropharyngeal cancer development. Patients with HPV DNA-positive tumors have been shown to be younger in age and are less likely to have a history of tobacco smoking or alcohol use. The tumors referred to the HPV positivity have been proven to more likely confer better prognosis. Seven percent of the population between ages of 14 and 69 are infected by HPV at any given time within the oral mucosa. However, only about 1 % of those infections is associated with the high-risk cancerogenous types of the virus. Up to date few risk factors of HPV infection have been identified including age, gender and the sexual behavior. Tobacco smoking and immunosuppression have also been reported to play a role in HPV infection. PMID- 27699531 TI - HPV-Related Head and Neck Squamous Cell Carcinomas. AB - Since more than 5 years, it becomes evident that there is a new group of patients with squamous cell carcinomas of the head and neck area, namely human papillomavirus (HPV)-related (caused) tumors. As clinical statistics indicate, those patients have better prognosis, even despite more advanced stage compared to those with HPV-negative tumors. In fact, as a surrogate of HPV infection for clinical studies, an immunohistochemical expression of p16 protein is used. In the following chapter, the spectrum of squamous cell carcinomas variants with indication of the percentage cases with proved HPV infection will be presented. PMID- 27699532 TI - HPV Testing of Head and Neck Cancer in Clinical Practice. AB - The pathology laboratory has a central role in providing human papillomavirus (HPV) tests for patients with head and neck cancer. There is an extensive literature around HPV testing and a large number of proprietary HPV tests, which makes the field difficult to navigate. This review provides a concise contemporary overview of the evidence around HPV testing in head and neck cancer and signposts key publications, guideline documents and the most commonly used methods in clinical practice. PMID- 27699533 TI - Variation of HPV Subtypes with Focus on HPV-Infection and Cancer in the Head and Neck Region. AB - The human papillomavirus (HPV) comprises a heterogeneous group of double-strand DNA viruses with variable potential to infect human epithelial cells and trigger neoplastic transformation. Its 8 kb genome encodes proteins required for virus replication and self-organized formation of infectious particles but also for early proteins E6 and E7 able to trigger neoplastic transformation. E6 and E7 of high-risk (HR) HPV subtypes can bind to p53 or release E2F and abrogate replication control. Due to variable amino acid sequence (AAS) in the binding sites of E6 and E7 particular HR-HPV variants within subtypes are essentially heterogeneous in efficacy triggering neoplastic transformation and cancer development. This could explain differences in the clinical course of HPV-driven head and neck cancer. PMID- 27699534 TI - Tumor Staging and HPV-Related Oropharyngeal Cancer. AB - The current TNM staging for oropharyngeal cancer (OSCC) was designed empirically for non-HPV-related disease. Emerging evidence suggests it is unsuited for Human papillomavirus (HPV)-related OSCC. Patients with HPV-positive tumors have improved prognosis, despite presenting at advanced stages. These shortcomings of the current staging system have been identified in single- and multi institutional trials. Patients with HPV related OSCC typically present with advanced N-stages leading to higher stage groupings. A rarity of stages I and II therefore represents the nature of HPV-related OSCC. Concerning prognosis of the patients, N-category and extracapsular spread seem to be of minor importance, whereas advanced T-stages result in unfavourable outcome. Anatomical staging therefore has been implied into different proposals to prognostic risk classifications in HPV-related disease as an additive compound. Prognostic risk groupings are further enhanced by incorporating non-anatomical factors. To summarize, it can be suggested that the current TNM system alone has little prognostic value in HPV-related OSCC. PMID- 27699535 TI - Human Papillomavirus (HPV): A Criterion for Therapeutic Decision in Squamous Cell Carcinoma of the Head and Neck? AB - When deciding how to treat patients with squamous cell carcinoma of the head and neck (SCCHN), several factors have to be taken into account: disease factors, patient factors, treatment factors, and the wish of the patient. This symposium article is summarizing the information on HPV (p16) in the context of decision making in SCCHN patients with locoregionally advanced disease and those with recurrent/metastatic disease. The literature data suggest that HPV(p16) has prognostic significance, both in locoregionally advanced disease (in particular, in oropharynx cancer) and in recurrent/metastatic disease, while there are only limited data on its predictive significance. Results of HPV (p16) testing should not change management outside clinical trials. PMID- 27699536 TI - Systemic Treatment in HPV-Induced Recurrent or Metastatic HNSCC. AB - Recurrent or metastatic head and neck cancer describes tumor deposits that arise locally, regionally, or at distant sites after treatment or distant metastases at the time of primary diagnosis. Prognosis for R/M squamous cell carcinomas of the head and neck (HNSCC) is poor and treatment options are limited in this situation. Human papillomavirus (HPV) is an important risk factor for HNSCC. About 40 % of all HNSCC have been attributed to HPV in Europe. HPV positivity at initial diagnosis is the single best prognostic factor for survival. However, data for the prognostic and predictive value of HPV in the R/M situation are still scarce. Due to the rising incidence of HPV-associated cancers, the number of R/M HPV+ carcinomas is also expected to rise. This chapter therefore aims to give an overview of the current knowledge concerning the role of HPV as a prognostic and predictive marker in recurrent or metastatic HNSCC. PMID- 27699537 TI - Optimizing Radiotherapy in HPV-Associated Oropharyngeal Cancer Patients. AB - Concurrent chemoradiation is considered the golden standard in the treatment of locally advanced OPC. However, given the very high survival rates in favorable HPV-positive OPC and the high rates of acute and late treatment-related side effects, de-escalation strategies have to be considered. In this chapter, the potential benefit of a number of de-escalation strategies is described, including of replacement of concurrent chemotherapy by cetuximab, radiation dose de escalation based on response to induction chemotherapy, radiotherapy alone without systemic treatment, and limiting elective nodal target volumes for radiation. In addition to de-escalation, modern radiation technologies like protons will offer increasing opportunities to decrease the dose to normal tissues in order to prevent radiation-induced toxicities. Initial analysis showed that radiation dose de-escalation based on response to induction chemotherapy in combination with intensity-modulated proton therapy (IMPT) has the highest potential to decrease acute and late toxicities. PMID- 27699538 TI - Should We De-escalate the Treatment for HPV-Positive Tumors? AB - De-escalation or de-intensification of therapy is discussed since many retrospective analyses of former trials demonstrated significantly better outcome for patients suffering from p16/HPV16-positive oropharyngeal squamous cell carcinoma of head and neck (OHNSCC). These observations are comprehensively addressed, but the reader has to keep in mind that none of the currently discussed data result from prospective controlled trials addressing the HPV discrimination in the primary endpoint design. Identification of the true HPV16 related tumors is still challenging and in addition with different clinical reports and lack of data of prospective trials not mature for routine clinical decision making in 2016. Independent of the currently lacking evidence for HPV dependent treatment de-escalation, there are some relevant arguments to address this question in ongoing and future trials. PMID- 27699539 TI - The Role of Conventional Surgery in Oropharyngeal Cancer. AB - Anatomically, the oropharynx can be divided into four subsites: the soft palate, pharyngeal wall, base of tongue, and the tonsillar complex. Surgical access to these tumours is often challenging due to the anatomic localization. For this reason, such tumours were traditionally managed with open surgical techniques, usually involving a mandibulotomy, to provide better visualization and access to the oropharynx, followed by free-flap reconstruction of the oropharyngeal defect. However, the invasiveness of this approach could lead to significant morbidity, including speech, swallowing, and airway dysfunction, in addition to poor cosmetic outcomes. In response, less invasive approaches (Mercante et al. 2013) have been developed including minimally invasive surgical approaches (chiefly transoral surgery) as well as non-surgical methods, primarily radiotherapy, and chemotherapy (Mercante et al. 2013). PMID- 27699540 TI - The Role of Surgery in the Management of Recurrent Oropharyngeal Cancer. AB - The incidence of oropharyngeal squamous cell carcinoma (OPSCC) continues to rise worldwide at a dramatic pace, buoyed by the predominance of human papilloma virus (HPV) driven disease (Panwar et al. 2014). While the outcomes of patients with HPV-positive OPSCC are dramatically improved compared to HPV-negative OPSCC, treatment failures do occur. The result is an inevitable rise in the incidence of recurrent OPSCC. Since the majority of incident OPSCC cases are treated with some form of radiation therapy (primary or adjuvant), surgery remains the backbone of treatment for recurrent OPSCC. This section will focus on options for surgical management of recurrent OPSCC. PMID- 27699541 TI - TORS in HPV-Positive Tumors-The New Standard? AB - In this chapter, we discuss implications of tumor site and tumor microenvironment properties of human papilloma virus (HPV)-associated cancer formation with special emphasis on the therapeutic modality of transoral robotic surgery (TORS). Over the past years, the development of robotic systems has improved, and therefore, its use in the surgical treatment of HNSCC has become a relevant treatment modality for many patients. Yet, there are limitations. Especially for endolaryngeal TORS procedures, additional technical development is mandatory, particularly with respect to visualization and manipulation. The Flex System has provided new additions that need to be further evaluated. TORS systems are going to improve technical issues and therefore reduce patient morbidity, surgical handling and treatment costs. The developed systems have to be tested and evaluated in prospective trials in order to be able to identify benefits and disadvantages in patient care. With respect to HPV-related OPSCC, TORS has become a valuable surgical alternative for an increasing number of patients. PMID- 27699542 TI - Risk Groups for Survival in HPV-Positive and HPV-Negative OPSCC. AB - Over the last three decades, it has become clear that infection with high-risk human papillomavirus (HPV) is etiologically linked to the development of head and neck squamous cell carcinomas, particularly those carcinomas that arise in the oropharyngeal region. PMID- 27699544 TI - Cancer Immunology and HPV. AB - HNSCC is a heterogeneous group of tumors located in the oral cavity, oropharynx, hypopharynx and larynx. Originally, tobacco and alcohol exposures were the main risk factors for HNSCC. In the last two decades, HPV infections have been identified as a risk factor for HNSCC, especially for oropharyngeal tumors. Whereas the HPV-induced oropharyngeal carcinomas predominantly express the HPV16 related E6 and E7 oncoproteins, the HPV-negative HNSCC are associated with an overexpression of p53. However, if the therapy successes for HPV-negative and HPV positive HNSCCs are compared, there are significantly higher total survival rates for HPV-positive oropharyngeal tumors compared to HPV-negative tumors. It is important to understand this phenomenon in order to improve and adapt therapy concepts. PMID- 27699543 TI - Predictive Factors for Outcome and Quality of Life in HPV-Positive and HPV Negative HNSCC. AB - Infection with high-risk types of the human papilloma virus (HPV) is an etiological risk factor for oropharyngeal squamous cell carcinoma (OPSCC) and associated with a better response to therapy and improved survival. A better understanding of the molecular principles underlying the differences in clinical behavior could pave the way to establish more effective and less toxic therapy for HPV-positive OPSCC and their HPV-negative counterparts. Compelling experimental evidence demonstrates that extensive global reprogramming of epigenetic profiles is as important as genetic mutations during neoplastic transformation and malignant progression, including HPV-positive OPSCC. In this chapter, the current knowledge on HPV-related alterations in DNA methylation, histone modification, and chromosome remodeling will be summarized and assessment of cancer-related profiles will be discussed as a valuable tool to gain important diagnostic or prognostic information for therapeutic decision-making and clinical management of HNSCC patients. PMID- 27699545 TI - Update on De-intensification and Intensification Studies in HPV. AB - In this chapter, we discuss de-esclation of treatment for patients with HPV positive disease. We discuss the rationale for de-escalation (why de-escalate?), patient selection criteria (who to de-esclate?) and what the treatment options for de-esclation are and the studies that are currently being run in those areas (how to de-escalate?). We stress the importance of clinicians NOT changing the management of oropharyngeal cancer patients outside clinical trials, and encourage them to recruit to the ongoing studies. PMID- 27699546 TI - Vaccination Expectations in HNSCC. AB - HPV-associated head and neck squamous cell carcinoma (HNSCC), more specifically the incidence of oropharyngeal cancer, is dramatically increasing in industrialized countries. According to what has been learned from anogenital vaccination programs, there are reasons to believe that current human papillomavirus (HPV) vaccinations may be potentially effective also against HNSCC. However, before specific results on HNSCC are available, one must keep in mind that carcinogenesis in the head and neck region may differ from that of the anogenital tract. Furthermore, the current evidence supports the view that HPV infection is much more complex than simply a sexually transmitted disease. HPV is present in the semen, placenta and in the newborns, and these infections of the newborns create cell-mediated immunity (CMI) against HPV, including the T memory cells. Acquisition of HPV infection in early life will rise new series of questions in the field of HPV vaccination.

AB - Based on the structure of MOF-808, different substituents were introduced to replace hydrogen atom on the phenyl ring of MOF-808. The GCMC method was used to study the effect of functional groups on the hydrogen storage properties of MOF 808-X (X = -OH, -NO2, -CH3, -CN, -I). The H2 uptakes and isosteric heat of adsorption were simulated at 77 K. The results indicate that all these substituents have favorable impact on the hydrogen storage capacity, and -CN is found to be the most promising substituent to improve H2 uptake. These results may be helpful for the design of MOFs with higher hydrogen storage capacity. Graphical abstract Atomistic structures of MOFs. (a) The structures of MOF-808-X.

AB - Novel chalcone derivatives with different substituents attached to A and B-rings: hydroxyl, methoxyl, geranyl, and prenyl groups were synthesized. The obtained compounds were characterized by NMR, HRMS, UV-Vis, IR, and MS. The theoretical analysis was carried out in all the compounds using density functional theory (DFT) with the B3LYP, PBE0, and M06-2X functionals in combination with the 6 311G(d,p) Pople-type basis set. The excited state properties were calculated by time dependent density functional theory (TD-DFT) using the same methodology applied for the ground state properties. The calculated vertical absorption wavelengths (lambdamax) in gas phase and in ethanol as a solvent are consistent with the experimental ones, being the TD-DFT:B3LYP/6-311G(d,p) and PCM-TD DFT:PBE0/6-311G(d,p) the best methodologies for these calculations with good approximation to the experimental values. The calculated reorganization energies indicated that, the four chalcone derivatives present an electron transfer character due to the smaller registered values. From these parameters it is proposed that these show an n-type semiconductor character. The localization of the frontier orbitals (HOMO and LUMO) shows that only the compound containing a hydroxyl group on the A-ring displays a marked delocalization favoring the charge transfer process in this system. The HOMO-LUMO gap energies indicate that the inclusion of different donor groups in the rings does not improve the obtained values for this property. Graphical Abstract Relationship between spectroscopic and geometrical properties of chalcones were carried out using quantum-chemical calculations and compared with experimental values. PMID- 27699553 TI - On the fly estimation of host-guest binding free energies using the movable type method: participation in the SAMPL5 blind challenge. AB - We review our performance in the SAMPL5 challenge for predicting host-guest binding affinities using the movable type (MT) method. The challenge included three hosts, acyclic Cucurbit[2]uril and two octa-acids with and without methylation at the entrance to their binding cavities. Each host was associated with 6-10 guest molecules. The MT method extrapolates local energy landscapes around particular molecular states and estimates the free energy by Monte Carlo integration over these landscapes. Two blind submissions pairing MT with variants of the KECSA potential function yielded mean unsigned errors of 1.26 and 1.53 kcal/mol for the non-methylated octa-acid, 2.83 and 3.06 kcal/mol for the methylated octa-acid, and 2.77 and 3.36 kcal/mol for Cucurbit[2]uril host. While our results are in reasonable agreement with experiment, we focused on particular cases in which our estimates gave incorrect results, particularly with regard to association between the octa-acids and an adamantane derivative. Working on the hypothesis that differential solvation effects play a role in effecting computed binding affinities for the parent octa-acid and the methylated octa-acid and that the ligands bind inside the pockets (rather than on the surface) we devised a new solvent accessible surface area term to better quantify solvation energy contributions in MT based studies. To further explore this issue a, molecular dynamics potential of mean force (PMF) study indicates that, as found by our docking calculations, the stable binding mode for this ligand is inside (rather than surface bound) the octa-acid cavity whether the entrance is methylated or not. The PMF studies also obtained the correct order for the methylation-induced change in binding affinities and associated the difference, to a large extent to differential solvation effects. Overall, the SAMPL5 challenge yielded in improvements our solvation modeling and also demonstrated the need for thorough validation of input data integrity prior to any computational analysis. PMID- 27699554 TI - Molecular docking performance evaluated on the D3R Grand Challenge 2015 drug-like ligand datasets. AB - The D3R Grand Challenge 2015 was focused on two protein targets: Heat Shock Protein 90 (HSP90) and Mitogen-Activated Protein Kinase Kinase Kinase Kinase 4 (MAP4K4). We used a protocol involving a preliminary analysis of the available data in PDB and PubChem BioAssay, and then a docking/scoring step using more computationally demanding parameters that were required to provide more reliable predictions. We could evidence that different docking software and scoring functions can behave differently on individual ligand datasets, and that the flexibility of specific binding site residues is a crucial element to provide good predictions. PMID- 27699555 TI - Adjuvant radiation use in older women with early-stage breast cancer at Johns Hopkins. AB - PURPOSE: In 2004, The National Comprehensive Cancer Network (NCCN) Guidelines incorporated omission of radiation therapy after breast-conservation surgery in women >=70 years old with stage I, estrogen receptor-positive breast cancer who plan to receive endocrine therapy. One study demonstrated wide variation in implementing this change across 13 NCCN institutions. We evaluated the practice pattern at our institution. METHODS: We identified women >=70 years old treated at our institution from 2009 to 2014. We calculated radiation therapy omission rate in those meeting the guidelines. We explored associations between radiation therapy omission, year of diagnosis, and patient characteristics with Wilcoxon rank sum tests and Fisher's exact tests. RESULTS: A total of 667 women met the inclusion criteria, and 117 (18 %) were candidates for radiation therapy omission. Mean age among the 117 was 76.3 years (Range: 70-95). Overall radiation therapy omission rate was 36.8 %, but varied greatly by year of diagnosis (Range: 7.7-54.5 %). This variation persisted after excluding women who did not receive endocrine therapy (Mean: 39.0 %, Range: 0.0-75.0 %). Factors associated with higher radiation therapy omission rates included older age and not having pathological nodal evaluation. The radiation therapy omission rate did not vary by race, tumor type, grade, or size. CONCLUSIONS: The implementation of the NCCN guideline has not been consistent at our institution. Our data suggest that other tools should be considered to apply the guidelines more consistently. We have implemented a quality improvement protocol that incorporates life expectancy estimate and geriatric assessment in women meeting the NCCN guideline at our institution. PMID- 27699556 TI - Testing whether patients with diabetes and healthy people perceive the meaning of the items in the Persian version of the SF-36 questionnaire similarly: a differential item functioning analysis. AB - PURPOSE: It has been rarely studied whether observed disparity in health-related quality-of-life (HRQoL) scores between patients with diabetes and healthy individuals is due to differential item functioning (DIF) or a true difference in the underlying construct. This study aimed to examine DIF in the SF-36 questionnaire and its effect on comparing HRQoL scores between patients with diabetes and healthy people. METHODS: The sample consisted of 230 patients with type 2 diabetes and 642 healthy individuals who filled out the Persian version of the SF-36 questionnaire. To detect DIF across patients with diabetes and healthy individuals, multiple-group multiple-indicator multiple-causes model was used. In addition, item calibration strategy was used to determine whether the effect of item-level DIF was transferred to the scale level. RESULTS: Nine out of thirty six (25 %) items were detected as DIF, of which one item (11 %) was flagged as uniform and eight items (89 %) as non-uniform DIF. Most of the DIF items were detected in the mental health component which includes vitality, perceived mental health and social functioning subscales rather than in physical health component. Moreover, nonsignificant latent mean differences for general health perception and social functioning subscales became significant after DIF calibration. CONCLUSION: The findings of the present study show that patients with diabetes and healthy individuals perceived some items in the SF-36 questionnaire differently. More importantly, in some subscales, the effect of item-level DIF was transferred to the scale level. Consequently, considerable caution should be taken in comparing HRQoL scores between patients with diabetes and healthy individuals. PMID- 27699557 TI - Oral health-related quality of life in youth receiving cleft-related surgery: self-report and proxy ratings. AB - PURPOSE: This paper evaluated the impact of cleft-related surgery on the oral health-related quality of life (OHRQoL) of youth with cleft over time. METHODS: Data were derived from a 5-year, multi-center, prospective, longitudinal study of 1196 youth with cleft lip and/or palate and their caregivers. Eligible youth were between 7.5 and 18.5 years old, spoke English or Spanish, and were non-syndromic. During each observational period, which included baseline, and 1- and 2-year post baseline follow-up visits, youths and their caregivers completed the Child Oral Health Impact Profile, a validated measure of OHRQoL. Multilevel mixed-effects models were used to analyze the effects of receipt of craniofacial surgery on OHRQoL over time. RESULTS: During the course of this study a total of 516 patients (43 %) received at least one surgery. Youth in the surgery recommendation group had lower self- (beta = -2.18, p < 0.05) and proxy-rated (beta = -2.92, p < 0.02) OHRQoL when compared to non-surgical self- and proxy rated OHRQoL at baseline. Both surgical and non-surgical youth (beta = 3.73, p < 0.001) and caregiver (beta = 1.91, p < 0.05) ratings of OHRQoL improved over time. There was significant incremental improvement (time * surgery interaction) in self-reported OHRQoL for youth postsurgery (beta = 1.04, p < 0.05), but this postsurgery increment was not seen in the caregiver proxy ratings. CONCLUSIONS: Surgical intervention impacts OHRQoL among youth with cleft. Youth who were surgical candidates had lower baseline self- and caregiver-rated OHRQoL when compared to non-surgical youth. Youth who underwent cleft-related surgery had significant incremental improvements in self-rated but not caregiver (proxy) rated OHRQoL after surgery. PMID- 27699559 TI - Multiple Equating of Separate IRT Calibrations. AB - When test forms are calibrated separately, item response theory parameters are not comparable because they are expressed on different measurement scales. The equating process includes the conversion of item parameter estimates on a common scale and the determination of comparable test scores. Various statistical methods have been proposed to perform equating between two test forms. This paper provides a generalization to multiple test forms of the mean-geometric mean, the mean-mean, the Haebara, and the Stocking-Lord methods. The proposed methods estimate simultaneously the equating coefficients that permit the scale transformation of the parameters of all forms to the scale of the base form. Asymptotic standard errors of the equating coefficients are derived. A simulation study is presented to illustrate the performance of the methods. PMID- 27699558 TI - Item Cloning Variation and the Impact on the Parameters of Response Models. AB - Item cloning is increasingly used to generate slight differences in tasks for use in psychological experiments and educational assessments. This paper investigates the psychometric issues that arise when item cloning introduces variation into the difficulty parameters of the item clones. Four models are proposed and evaluated in simulation studies with conditions representing possible types of variation due to item cloning. Depending on the model specified, unaccounted variance in the item clone difficulties propagates to other parameters in the model, causing specific and predictable patterns of bias. Person parameters are largely unaffected by the choice of model, but for inferences related to the item parameters, the choice is critical and can even be leveraged to identify problematic item cloning.

AB - The purpose of this note is to focus on the finiteness of the weighted likelihood estimator (WLE) of ability in the context of dichotomous and polytomous item response theory (IRT) models. It is established that the WLE always returns finite ability estimates. This general result is valid for dichotomous (one-, two , three- and four-parameter logistic) IRT models, the class of polytomous difference models and divide-by-total models, independently of the number of items, the item parameters and the response patterns.

AB - We develop a latent variable selection method for multidimensional item response theory models. The proposed method identifies latent traits probed by items of a multidimensional test. Its basic strategy is to impose an [Formula: see text] penalty term to the log-likelihood. The computation is carried out by the expectation-maximization algorithm combined with the coordinate descent algorithm. Simulation studies show that the resulting estimator provides an effective way in correctly identifying the latent structures. The method is applied to a real dataset involving the Eysenck Personality Questionnaire.

AB - The study examined sexual delay discounting, or the devaluation of condom protected sex in the face of delay, as a risk factor for sexually transmitted infection (STI) among college students. Participants (143 females, 117 males) completed the sexual delay discounting task (Johnson & Bruner, 2012) and questionnaires of risky sexual behavior, risk perception, and knowledge. Participants exhibited steeper sexual delay discounting (above and beyond general likelihood of having unprotected sex) when partners were viewed as more desirable or less likely to have a STI, with males demonstrating greater sexual delay discounting than females across most conditions. Importantly, greater self reported risky sexual behaviors were associated with higher rates of sexual delay discounting, but not with likelihood of using a condom in the absence of delay. These results provide support for considering sexual delay discounting, with particular emphasis on potential delays to condom use, as a risk factor for STI among college students. PMID- 27699563 TI - Randomized Comparison of Subcuticular Sutures Versus Staples for Skin Closure After Open Abdominal Surgery: a Multicenter Open-Label Randomized Controlled Trial. AB - BACKGROUND: The incisional surgical site infection (SSI) is an extremely common complication following open abdominal surgery and imposes a considerable treatment and cost burden. METHOD: We conducted a multicenter open-label randomized controlled trial at three Tokyo Metropolitan medical institutions. We enrolled adult patients who underwent either an elective or an emergency open laparotomy. Eligible patients were allocated preoperatively to undergo wound closure with either subcuticular sutures or staples. A central Web-based randomization tool was used to assign participants randomly by a permuted block sequence with a 1:1 allocation ratio and a block size of 4 before mass closure to each group. The primary endpoint was the occurrence of a superficial SSI within 30 days after surgery in accordance with the Centers for Disease Control and Prevention criteria. This trial was registered with UMIN-CTR as UMIN 000004836 ( http://www.umin.ac.jp/ctr ). RESULTS: Between September 1, 2010 and August 31, 2015, 401 patients were enrolled and randomly assigned to either group. One hundred and ninety-nine patients were allocated to the subcuticular suture and 202 patients to the staple groups (hereafter the "suture" and "staple" group, respectively). Three hundred and ninety-nine were eligible for the primary endpoint. Superficial SSIs occurred in 25 of 198 suture patients and in 27 of 201 staple patients. Overall, the rate of superficial SSIs did not differ significantly between the suture and staple groups. CONCLUSION: Subcuticular sutures did not increase the occurrence of superficial SSIs following open laparotomies mainly consisting of clean-contaminated surgical procedures. The applicability of the wound closure material and method is likely to depend on individual circumstances of the patient and surgical procedure.

AB - The regulatory decision-making process regarding chemical safety is most often informed by evidence based on ecotoxicity tests that consider growth, reproduction and survival as end-points, which can be quantitatively linked to short-term population outcomes. Changes in these end-points resulting from chemical exposure can cause alterations in micro-evolutionary forces (mutation, drift, selection and gene flow) that control the genetic composition of populations. With multi-generation exposures, anthropogenic contamination can lead to a population with an altered genetic composition, which may respond differently to future stressors. These evolutionary changes are rarely discussed in regulatory or risk assessment frameworks, but the growing body of literature that documents their existence suggests that these important population-level impacts should be considered. In this meta-analysis we have compared existing contamination levels of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) that have been documented to be associated with evolutionary changes in resident aquatic organisms to regulatory benchmarks for these contaminants. The original intent of this project was to perform a meta-analysis on evolutionary events associated with PCB and PAH contamination. However, this effort was hindered by a lack of consistency in congener selection for "total" PCB or PAH measurements. We expanded this manuscript to include a discussion of methods used to determine PCB and PAH total contamination in addition to comparing regulatory guidelines and contamination that has caused evolutionary effects. Micro-evolutionary responses often lead populations onto unique and unpredictable trajectories. Therefore, to better understand the risk of population-wide alterations occurring, we need to improve comparisons of chemical contamination between affected locations. In this manuscript we offer several possibilities to unify chemical comparisons for PCBs and PAHs that would improve comparability among evolutionary toxicology investigations, and with regulatory guidelines. In addition, we identify studies documenting evolutionary change in the presence of PCB and PAH contamination levels below applicable regulatory benchmarks. PMID- 27699565 TI - Predictors of Elopement Exhibited by School-Aged Children With Special Health Care Needs: Towards the Development of a Screening Instrument for Elopement. AB - Elopement exhibited by school-aged children with special health care needs is a relatively low frequency problem behavior with the potential for severe negative consequences for the child and family. Using data from the Centers for Disease Control and Prevention (CDC) Survey of Pathways to Diagnosis and Services, our results represent one of the first empirical studies of variables that may be associated with children with special health care needs engaging in elopement. Using data from a nationally representative sample of children with special health care needs, our results revealed two variables that were statistically significant predictors of parent-reported elopement in the past year: (1) the child's chronological age, and (2) the presence of an autism spectrum disorder (ASD) diagnosis. We found that the likelihood of an elopement event was inversely related to age, but positively associated with the presence of an ASD diagnosis. Using parent-response items from the CDC data set, we selected a set of questions to screen for risk of elopement and analyzed their psychometric properties. We discuss the need for future research to validate this screening instrument for school-aged youth with special health care needs. Our study provides an initial psychometric analysis to support a potential screening instrument for elopement events among school-aged youth that needs to be validated by a longitudinal study of its predictive validity. PMID- 27699566 TI - Long-Term Outcomes of the Laparoscopic Adjustable Gastric Banding: Weight Loss and Removal Rate. A Single Center Experience on 301 Patients with a Minimum Follow-Up of 10 years. AB - BACKGROUND: Obesity is a chronic disease that requires procedures to enable to maintain good long-term results. Laparoscopic adjustable gastric banding (LAGB) studies with a long-term follow-up are limited and have often given conflicting results. We report our results in terms of banding life span and weight loss in a cohort of 301 patients operated on LAGB with a minimum follow-up of 10 years. METHODS: All patients who underwent LAGB at our university hospital between 1998 and 2004 were included in this study. The main outcome was band survival and complications that led to band removal, and the secondary outcome was weight loss. We present raw data and data after imputation for patients lost at follow up. RESULTS: Most patients were women (83 %), and the mean body mass index (BMI) baseline was 45.2 +/- 6.7. The pars flaccida technique was performed in 50.9 % of the patients. All patients had at least 10 years of follow-up (range 10-16 years). Data were available at 10 years for 79.7 % and at 15 years for 80.6 %. Band survival was 65.8 % at 10 years and 53.3 % at 15 years. Mean excess weight loss (EWL) at 5, 10, and 15 years was 41.4, 38.7, and 35.1 %, respectively. CONCLUSION: Despite the encouraging short-term results, LAGB shows long-term disappointing results in terms of weight loss and complication rates. The removal rate increases with time (about 3-4 % per year), and at 15 years, almost half of the bands had been removed. PMID- 27699567 TI - Health-economic evaluation of home telemonitoring for COPD in Germany: evidence from a large population-based cohort. AB - INTRODUCTION: Telemonitoring for COPD has gained much attention thanks to its potential of reducing morbidity and mortality, healthcare utilisation and costs. However, its benefit with regard to clinical and economic outcomes remains to be clearly demonstrated. OBJECTIVE: To analyse the effect of Europe's largest COPD telemonitoring pilot project on direct medical costs, health resource utilisation and mortality at 12 months. METHODS: We evaluated a population-based cohort using administrative data. Difference-in-difference estimators were calculated to account for time-invariant unobservable heterogeneity after removing dissimilarities in observable characteristics between the telemonitoring and control group with a reweighting algorithm. RESULTS: The analysis comprised 651 telemonitoring participants and 7047 individuals in the standard care group. The mortality hazards ratio was lower in the intervention arm (HR 0.51, 95 % CI 0.30 0.86). Telemonitoring cut total costs by 895 ? (p < 0.05) compared to COPD standard care, mainly driven by savings in COPD-related hospitalisations in (very) severe COPD patients (-1056 ?, p < 0.0001). Telemonitoring enrolees used healthcare (all-cause and COPD-related) less intensely with shorter hospital stays, fewer inpatient stays and smaller proportions of people with emergency department visits and hospitalisations (all p < 0.0001). Reductions in mortality, costs and healthcare utilisation were greater for (very) severe COPD cases. CONCLUSION: This is the first German study to demonstrate that telemonitoring for COPD is a viable strategy to reduce mortality, healthcare costs and utilisation at 12 months. Contrary to widespread fear, reducing the intensity of care does not seem to impact unfavourably on health outcomes. The evidence offers strong support for introducing telemonitoring as a component of case management.

AB - This study aims to estimate the mean annual social cost per patient with chronic kidney disease (CKD) by stages 4 and 5 pre-dialyses and cost components in Italy. The multicenter cross-sectional study included all adult outpatients in charge of the 14 main Nephrology Centers of Tuscany Region during 7 weeks from 2012 to 2013. Direct medical costs have been estimated using tariffs for laboratory tests, diagnostic exams, visits, hospitalization and prices for drugs. Non medical costs included expenses of low-protein special foods, travel, and formal and informal care. Patients' and caregivers' losses of productivity have been estimated as indirect costs using the human capital approach. Costs have been expressed in Euros (2016). Totals of 279 patients in stage 4 and 205 patients in stage 5 have been enrolled. The estimated mean annual social cost of a patient with CKD were ?7422 (+/-?6255) for stage 4 and ?8971 (+/-?6503) for stage 5 (p < 0.05). Direct medical costs were higher in stage 5 as compared to stage 4; direct non-medical costs and indirect costs accounted, respectively, for 41 and 5 % of the total social cost of CKD stage 4 and for 33 and 9 % of CKD stage 5. In Italy, the overall annual social cost of CKD was ?1,809,552,398 representing 0.11 % of the Gross Domestic Product. Direct non-medical costs and indirect costs were weighted on the social cost of CKD almost as much as the direct medical cost. Patients, their families and the productivity system sustain the burden of the disease almost as much as the healthcare system.

PMID- 27699571 TI - Clinical, Immunological, and Molecular Findings of Patients with p47phox Defect Chronic Granulomatous Disease (CGD) in Indian Families. AB - Chronic granulomatous disease (CGD) is a group of inherited disorder of phagocytes, resulting from mutations in the components of the NADPH oxidase complex. Reduced or absent oxygen radical synthesis seen in these patients leads to impaired killing of intracellular bacteria and fungi. CGD clinically presents with recurrent and life-threatening infections as well as granulomatous inflammatory responses. p47phox encoded by the NCF1 gene is the most common autosomal recessive form of CGD which is often clinically milder. Here, we are presenting the data on clinical and immunological findings in 21 Indian patients with Del GT mutation in the NCF1 gene. Diagnosis of these patients was based on detailed clinical evaluation, measurement of respiratory burst activity by nitro blue tetrazolium and dihydrorhodamine-1,2,3 assay, expression of p47phox by flow cytometry, and molecular confirmation by GeneScan method. Seventeen male and four female patients with median age of onset of 1 year ranging from 1.5 months to 6 years were included in the study. Sixty-two percent (13 out of 21) of patients belonged to a consanguineous marriage with only one family having a history of a previous sibling death. Significant variability in clinical presentation was observed in spite of identical genetic defect ranging from asymptomatic to very severe presentation leading to early death or requiring transplantation. However, none of these patients showed difference in immunological parameters to account for this variability. Thus, this study highlights the phenotypic heterogeneity seen in these patients with Del GT mutation in the NCF1 gene and its implication in management of these patients. PMID- 27699573 TI - Direct communication between osteocytes and acid-etched titanium implants with a sub-micron topography. AB - The osteocyte network, through the numerous dendritic processes of osteocytes, is responsible for sensing mechanical loading and orchestrates adaptive bone remodelling by communicating with both the osteoclasts and the osteoblasts. The osteocyte network in the vicinity of implant surfaces provides insight into the bone healing process around metallic implants. Here, we investigate whether osteocytes are able to make an intimate contact with topologically modified, but micrometre smooth (S a < 0.5 um) implant surfaces, and if sub-micron topography alters the composition of the interfacial tissue. Screw shaped, commercially pure (cp-Ti) titanium implants with (i) machined (S a = ~0.2 um), and (ii) two-step acid-etched (HF/HNO3 and H2SO4/HCl; S a = ~0.5 um) surfaces were inserted in Sprague Dawley rat tibia and followed for 28 days. Both surfaces showed similar bone area, while the bone-implant contact was 73 % higher for the acid-etched surface. By resin cast etching, osteocytes were observed to maintain a direct intimate contact with the acid-etched surface. Although well mineralised, the interfacial tissue showed lower Ca/P and apatite-to-collagen ratios at the acid etched surface, while mineral crystallinity and the carbonate-to-phosphate ratios were comparable for both implant surfaces. The interfacial tissue composition may therefore vary with changes in implant surface topography, independently of the amount of bone formed. Implant surfaces that influence bone to have higher amounts of organic matrix without affecting the crystallinity or the carbonate content of the mineral phase presumably result in a more resilient interfacial tissue, better able to resist crack development during functional loading than densely mineralised bone. PMID- 27699572 TI - Primary Immunodeficiency Diseases in Oman: 10-Year Experience in a Tertiary Care Hospital. AB - PURPOSE: Primary immunodeficiency (PID) diseases are rare, complex medical disorders that often are overlooked in clinical settings. There are emerging reports of PID from Middle Eastern populations. This study describes the features of PID patients in a tertiary care setting in Oman and compares them with regional and worldwide reports. METHOD: Sultan Qaboos University Hospital (SQUH) is an academic tertiary care-level hospital for specialized healthcare, including PID patients. At the time of diagnosis, patients' sociodemographics, clinical features, laboratory investigations, and management were entered in electronic form. This study included patients seen between August 2005 and July 2015. RESULTS: One hundred forty patients were registered with a minimum estimated population prevalence of 7.0/100,000. The male/female ratio was 1.6:1, the median age of onset of symptoms was 8 months, and diagnosis was 21 months with a delay of 13 months. Family history was positive in 44 %, consanguinity was present in 76 %, death of a previous sibling was present in 36 %, and there was an overall mortality in 18 %, with an 85 % probability of survival 10 years following diagnosis. The most common type of immunodeficiency was phagocytic disorders (35.0 %), followed by predominantly antibody disorders (20.7 %), combined immunodeficiency (17.8 %), other well-defined PID syndromes (15.0 %), immune dysregulation syndromes (3.5 %), complement deficiencies (3.5 %), and unclassified immunodeficiency (4.2 %). The commonest presenting infection was pneumonia (47.1 %). CONCLUSION: PID is not a rare condition in Oman. The prevalence is in concordance with reports from the region but higher than in Western populations. The findings of the current study would help to improve the awareness and management of, and policy making for PID. PMID- 27699574 TI - Effect of bioactive dental adhesive on periodontal and endodontic pathogens. AB - The objectives of this study were to: (1) develop a new bioactive dental bonding agent with nanoparticles of amorphous calcium phosphate and dimethylaminohexadecyl methacrylate for tooth root caries restorations and endodontic applications, and (2) investigate biofilm inhibition by the bioactive bonding agent against eight species of periodontal and endodontic pathogens for the first time. Bonding agent was formulated with 5 % of dimethylaminohexadecyl methacrylate. Nanoparticles of amorphous calcium phosphate at 30 wt% was mixed into adhesive. Eight species of biofilms were grown on resins: Porphyromonas gingivalis, Prevotella intermedia, Prevotella nigrescens, Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Parvimonas micra, Enterococcus faecalis, Enterococcus faecium. Colony-forming units, live/dead assay, biomass, metabolic activity and polysaccharide of biofilms were determined. The results showed that adding dimethylaminohexadecyl methacrylate and nanoparticles of amorphous calcium phosphate into bonding agent did not decrease dentin bond strength (P > 0.1). Adding dimethylaminohexadecyl methacrylate reduced the colony forming units of all eight species of biofilms by nearly three orders of magnitude. The killing efficacy of dimethylaminohexadecyl methacrylate resin was: P. gingivalis > A. actinomycetemcomitans > P. intermedia > P. nigrescens > F. nucleatum > P. micra > E. faecalis > E. faecium. Dimethylaminohexadecyl methacrylate resin had much less biomass, metabolic activity and polysaccharide of biofilms than those without dimethylaminohexadecyl methacrylate (P < 0.05). In conclusion, a novel dental adhesive was developed for root caries and endodontic applications, showing potent inhibition of biofilms of eight species of periodontal and endodontic pathogens, and reducing colony-forming units by three orders of magnitude. The bioactive adhesive is promising for tooth root restorations to provide subgingival margins with anti-periodontal pathogen capabilities, and for endodontic sealer applications to combat endodontic biofilms. PMID- 27699575 TI - Analysis of thrombosis and bleeding complications in patients with polycythemia vera: a Turkish retrospective study. AB - The aims of this study are to determine the incidence and risk factors of thrombosis and bleeding in polycythemia vera (PV) patients and to research the effects of these risk factors on survival. The medical records of 155 PV patients were analyzed retrospectively. Patients were divided into groups according to whether or not thrombosis had developed in follow-up, and according to whether or not bleeding had occurred during follow-up. The mean age at diagnosis was 53 years, and the mean follow-up period was 66 months. The percentage of cases in which thrombosis events had occurred before diagnosis and during follow-up were 26 and 28 %, respectively. Comparisons of disease duration and average thrombosis risk score between groups with or without thrombosis drew statistically significant results. A patient's history of thrombosis and thrombocytosis at first visit was found to have a significant effect on thrombosis recurrence. The major bleeding rate was 8 %. Post-PV myelofibrosis was an independent risk factor for bleeding. The major cause of death among the patients in this study was primary thrombosis. The most important causes of mortality among PV patients are thrombosis, and the most prominent risk factors for thrombosis development are disease duration and high thrombosis risk scores. Thrombocytosis in patients with a history of thrombosis may cause thrombosis recurrence during the follow-up period.

AB - The skin is a possible site of extramedullary localization in multiple myeloma (MM) patients; however, the mechanisms involved in this process are poorly understood. We describe the case of a refractory MM patient who developed a cutaneous localization under bortezomib treatment and we further expanded observations in other eight MM patients. We focused on the expression of genes involved in plasma cell skin homing, including CCR10, which was highly expressed. Moreover, we observed a lack of CXCR4 surface expression and the down-regulation of ICAM1/CD54 throughout the progression of the disease, suggesting a possible mechanism driving the escape of MM cells from the bone marrow into the skin. PMID- 27699578 TI - Re-initiation of biologics after the development of tuberculosis under anti-TNF therapy. AB - The use of anti-TNF agents is associated with an increased risk of tuberculosis (TB) and anti-TNF agents are stopped when active TB develops. However, discontinuation of treatment can result in flare of the underlying disease. The charts of 22 patients who developed active TB among a cohort of 2754 patients using anti-TNF agents between 2001 and 2013 were reviewed retrospectively. Patients restarting biologics during further follow-up were identified. One patient with miliary TB died within 1 month. A biologic agent was restarted in 16 of the remaining 21 patients (76 %). The most frequently re-initiated biologic agent was etanercept (n = 6) followed by rituximab (n = 5) and interferon-alpha (n = 3). Biologic treatment was re-initiated during anti-TB treatment in four patients and after completing TB treatment in 12 patients. The median follow-up after restarting biologics was 53 (IQR: 40-75) months. TB re-occurred in one patient with Behcet's syndrome, who initially received etanercept due to severe sight-threatening uveitis at the third month of anti-TB treatment followed by canakinumab 15 months later along with methotrexate, cyclosporine and corticosteroids. After a second course of 9 months TB therapy this patient is currently stable on interferon-alpha for 33 months. Restarting of anti-TNF agents and other biologic agents, even during TB treatment, seems to be possible among patients who had previously developed TB under anti-TNF treatment. However, the risk of re-development of TB infection mandates careful follow-up. PMID- 27699579 TI - Postoperative dysglycemia in elective non-diabetic surgical patients: a prospective observational study. AB - PURPOSE: Elevated glycosylated hemoglobin (HbA1c) is often found in surgical patients with no history of diabetes. The purpose of this prospective observational study was to determine if elevated preoperative HbA1c is associated with postoperative hyperglycemia in non-diabetic surgical patients and to identify predictors of elevated HbA1c. METHODS: This study included 257 non diabetic adults scheduled for inpatient surgery. Preoperatively, capillary blood glucose (CBG) and HbA1c were measured and patients completed the Canadian Diabetes Risk Questionnaire (CANRISK). Capillary blood glucose was measured for two days or until hospital discharge at the following time points: postoperatively, before all meals, and at 22:00 hr. The mean CBG and incidence of hyperglycemia were compared between HbA1c levels: Group I < 6.0%, Group II 6.0 6.4%, and Group III >= 6.5%. RESULTS: The mean postoperative glucose levels at all time points were significantly higher in Group III compared with Groups I and II (P < 0.01). At least one episode of hyperglycemia (CBG >= 10.0 mMol.L-1) occurred in 61% (11/18) of patients in Group III vs 11% (23/209) of patients in Group I (relative risk, 5.55; 95% confidence interval [CI], 3.26 to 9.47; P < 0.001). Elevated glycosylated hemoglobin >= 6.0% was found in 31% (33/107) of those with a high CANRISK score. The best predictors of postoperative hyperglycemia were preoperative CBG > 6.9 mMol.L-1 [diagnostic odds ratio (OR) (reference < 6.0 mMol.L-1), 4.16; 95% CI, 1.57 to 10.98; P = 0.004], HbA1c >= 6.0% [OR (reference < 6.0%), 3.00; 95% CI, 1.39 to 6.49; P = 0.005], and HbA1c >= 6.5% [OR (reference < 6.5%), 13.45; 95% CI, 4.78 to 37.84; P <0.001]. CONCLUSIONS: Elevated HbA1c is associated with higher mean postoperative glucose levels in patients with no diabetic history. The CANRISK score is a strong predictor of elevated HbA1c, while CBG and HbA1c are both predictors of postoperative hyperglycemia. PMID- 27699581 TI - Mental and Physical Health among Homeless Sexual and Gender Minorities in a Major Urban US City. AB - Sexual and gender minorities have been shown to have greater rates of mental health, substance use disorders, and specific types of health problems compared to heterosexuals. Among the homeless population in several US urban areas, sexual and gender minorities are overrepresented but few studies have examined the mental and physical health status of homeless sexual and gender minorities, with studies on homeless gender minorities being particularly hard to find. Using survey data obtained from the city and county of San Francisco (2015 Homeless Survey), this study examined differences in causes of homelessness, physical and mental health problems, and domestic violence among homeless sexual and gender minorities and their heterosexual and cisgender (i.e., non-transgender) counterparts, respectively. Lesbians and bisexual women, and gay and bisexual men did not differ from their cisgender heterosexual counterparts. Cisgender men who identified as queer or "other" in response to sexual orientation questions had higher rates of psychiatric problems and posttraumatic stress disorder, while cisgender women who identified as queer or "other" had higher rates of psychiatric problems and drug and alcohol use. Transgender men who were homeless were found to be particularly at risk for physical health problems, mental health problems, and domestic violence or abuse. Transgender women were more likely to report posttraumatic stress disorder. This study suggests that transgender men and cisgender sexual minority men and women who identify as queer or "other" are groups among the homeless that may benefit from increased outreach and services. PMID- 27699582 TI - Peroxisome proliferator-activated receptor gamma co-activator 1 gene Gly482Ser polymorphism is associated with the response of low-density lipoprotein cholesterol concentrations to exercise training in elderly Japanese. AB - Muscle peroxisome proliferator-activated receptor gamma co-activator 1 (PGC 1)alpha gene expression is influenced by the Gly482Ser gene polymorphism, which is a candidate genetic risk factor for diabetes mellitus and obesity. This study investigated the effects of PGC-1 gene Gly482Ser polymorphisms on alterations in glucose and lipid metabolism induced by exercise training. A 12-week intervention study was performed for 119 participants who were more than 65 years of age and completed exercise training at lactate threshold intensity. Total cholesterol and low-density lipoprotein cholesterol were significantly reduced in Gly/Gly but not in Gly/Ser and Ser/Ser participants after exercise. The Gly/Gly genotype of the PGC-1 gene Gly482Ser polymorphism influences the effects of moderate-intensity exercise training on low-density lipoprotein cholesterol and total cholesterol concentrations in older people. PMID- 27699580 TI - Inflammasomes and its importance in viral infections. AB - A complex interplay between pathogen and host determines the immune response during viral infection. A set of cytosolic sensors are expressed by immune cells to detect viral infection. NOD-like receptors (NLRs) comprise a large family of intracellular pattern recognition receptors. Members of the NLR family assemble into large multiprotein complexes, termed inflammasomes, which induce downstream immune responses to specific pathogens, environmental stimuli, and host cell damage. Inflammasomes are composed of cytoplasmic sensor molecules such as NLRP3 or absent in melanoma 2 (AIM2), the adaptor protein ASC (apoptosis-associated speck-like protein containing caspase recruitment domain), and the effector protein procaspase-1. The inflammasome operates as a platform for caspase-1 activation, resulting in caspase-1-dependent proteolytic maturation and secretion of interleukin (IL)-1beta and IL-18. This, in turn, activates the expression of other immune genes and facilitates lymphocyte recruitment to the site of primary infection, thereby controlling invading pathogens. Moreover, inflammasomes counter viral replication and remove infected immune cells through an inflammatory cell death, program termed as pyroptosis. As a countermeasure, viral pathogens have evolved virulence factors to antagonise inflammasome pathways. In this review, we discuss the role of inflammasomes in sensing viral infection as well as the evasion strategies that viruses have developed to evade inflammasome dependent immune responses. This information summarises our understanding of host defence mechanisms against viruses and highlights research areas that can provide new approaches to interfere in the pathogenesis of viral diseases. PMID- 27699583 TI - Prostaglandins mediate zymosan-induced sickness behavior in mice. AB - Previous studies have demonstrated that zymosan, a cell wall component of the yeast Saccharomyces cerevisiae, induces inflammation in experimental models. However, few studies have evaluated the potential of zymosan to induce sickness behavior, a central motivational state that allows an organism to cope with infection. To determine whether zymosan administration results in sickness behavior, mice were submitted to the forced swim (FST) and open field (OFT) tests 2, 6, and 24 h after treatment with zymosan (1, 10, or 100 mg/kg). Additionally, to evaluate the possible relationship between zymosan-induced sickness behavior and prostaglandin synthesis, mice were pretreated with the cyclooxygenase inhibitors indomethacin (10 mg/kg) and nimesulide (5 mg/kg) and the glucocorticoid drug dexamethasone (1 mg/kg). Zymosan induced time-dependent decreases in locomotor activity in the OFT, and an increase in immobility in the FST, and increased plasma levels of corticosterone at 2 h. Pretreatment with indomethacin, nimesulide, or dexamethasone blocked zymosan-induced behavioral changes in both the FST and OFT at 2 h post administration. These findings confirm previous observations that zymosan induces sickness behavior. Furthermore, our results provide new evidence that prostaglandin synthesis is necessary for this effect, as anti-inflammatory drugs that inhibit prostaglandin synthesis attenuated zymosan-induced behavioral changes. PMID- 27699584 TI - Ceritinib: a Review in ALK-Positive Advanced NSCLC. AB - Ceritinib (ZykadiaTM) is an oral, selective inhibitor of the anaplastic lymphoma kinase (ALK), a receptor tyrosine kinase which, after genetic rearrangement, acts as an oncogenic driver in a proportion of non-small cell lung cancers (NSCLCs). The drug is approved in several countries worldwide for the treatment of patients with ALK-positive, advanced NSCLC who have previously received the first generation ALK inhibitor crizotinib (indication details may vary by country). Approval was based on its clinical benefit in this setting in the phase I and II trials known as ASCEND-1 and -2. Across these noncomparative studies, 36-56 % of patients achieved a response with ceritinib (at the recommended dosage of 750 mg once daily) and the responses were durable, lasting up to a median of 10 months. Patients survived free from progression for a median of up to 7 months and had a median overall survival of up to 17 months. Moreover, efficacy outcomes in patients with brain metastases were generally consistent with those of the overall study populations. Ceritinib has an acceptable tolerability profile, with gastrointestinal issues, fatigue and liver test abnormalities being the most common adverse reactions. Thus, ceritinib is a valuable treatment option for patients with ALK-positive advanced NSCLC who have already received crizotinib therapy.

PMID- 27699586 TI - Non-invasive Vagus Nerve Stimulation (nVNS) as mini-prophylaxis for menstrual/menstrually related migraine: an open-label study. AB - BACKGROUND: Menstrual migraine and menstrually related migraine attacks are typically longer, more disabling, and less responsive to medications than non menstrual attacks. The aim of this study was to evaluate the efficacy, safety, and tolerability of non-invasive vagus nerve stimulation for the prophylactic treatment of menstrual migraine/menstrually related migraine. METHODS: Fifty-six enrolled subjects (menstrual migraine, 9 %; menstrually related migraine, 91 %), 33 (59 %) of whom were receiving other prophylactic therapies, entered a 12-week baseline period. Fifty-one subjects subsequently entered a 12-week treatment period to receive open-label prophylactic non-invasive vagus nerve stimulation adjunctively (31/51; 61 %) or as monotherapy (20/51; 39 %) on day -3 before estimated onset of menses through day +3 after the end of menses. RESULTS: The number of menstrual migraine/menstrually related migraine days per month was significantly reduced from baseline (mean +/- standard error, 7.2 +/- 0.7 days) to the end of treatment (mean +/- standard error, 4.7 +/- 0.5 days; P < 0.001) (primary end point). Of all subjects, 39 % (95 % confidence interval: 26 %, 54 %) (20/51) had a >= 50 % reduction (secondary end point). For the other secondary end points, clinically meaningful reductions in analgesic use (mean change +/- standard error, -3.3 +/- 0.6 times per month; P < 0.001), 6-item Headache Impact Test score (mean change +/- standard error, -3.1 +/- 0.7; P < 0.001), and Migraine Disability Assessment score (mean change +/- standard error, -11.9 +/- 3.4; P < 0.001) were observed, along with a modest reduction in pain intensity (mean change +/- standard error, -0.5 +/- 0.2; P = 0.002). There were no safety/tolerability concerns. CONCLUSIONS: These findings suggest that non invasive vagus nerve stimulation is an effective treatment that reduces the number of menstrual migraine/menstrually related migraine days and analgesic use without safety/tolerability concerns in subjects with menstrual migraine/menstrually related migraine. Randomised controlled studies are warranted. PMID- 27699587 TI - Effects of Antihypertensive Therapy on Blood Pressure Variability. AB - PURPOSE OF REVIEW: The study aims to summarize the effect of antihypertensive therapy on various types of BP variability in hypertensives. RECENT FINDINGS: Visit-to-visit, day-by-day, and ambulatory BPV are markers of target organ damage and cardiovascular prognosis, as was shown in the LIFE study, which showed that visit-to-visit variability in BP predicted cardiovascular events in treated hypertensive patients with left ventricular hypertrophy. Long-acting calcium channel blockers (CCBs) may be a preferable treatment in reducing BPV measures. Non-adherence to antihypertensive medication is also a very important component of increased BPV, and improving the adherence is also a key for the favorable prognosis. BPV cannot be a target of antihypertensive treatments because of the lack of definitive evidence. However, in high-risk patients, those with cardiovascular or cerebrovascular diseases, the clinical significance should be considered in individual basis. Especially, reduction of BPV would be an important strategy for these patients. PMID- 27699589 TI - Cinobufotalin impedes Sw.71 cytotrophoblast cell line function via cell cycle arrest and apoptotic signaling. AB - Preeclampsia (preE) is a hypertensive disorder of pregnancy. Cardiotonic steroids (CTS) are endogenous inhibitors of Na+/K+ ATPase, and at least one CTS, marinobufagenin (MBG), is elevated in a rat model of preE prior to the development of the syndrome. MBG and ouabain impair cytotrophoblast (CTB) cell function, which is critical for placental development. We evaluated the effect of a CTS, cinobufotalin (CINO), on CTB cell function in vitro. CINO at >=1 nM inhibited CTB cell proliferation, migration, and invasion (p < 0.05), but had no effect on cell viability. There was a higher (p < 0.05) percentage of G0/G1 phase cells in groups treated with CINO at >=1 nM. CINO caused an increase in stress signaling p38 MAPK and a positive annexin-V staining in CTB cells, indicating the activation of apoptotic signaling. However, the CINO-induced apoptotic signaling was prevented by p38 inhibition. These data demonstrate that CINO impairs CTB cell function via cell cycle arrest and apoptotic signaling.

PMID- 27699588 TI - The protein-interaction network with functional roles in tumorigenesis, neurodegeneration, and aging. AB - The present review summarizes the knowledge about a protein-interaction network, which includes proteins with significant functions in the mechanisms of aging and age-related diseases. All the detected interacting proteins TPPII, p53, MYBBP1A, CDK2 and SIRT7, SIRT6, and CD147 are suitable for the development of antitumor therapeutics and treatments for diseases of aging. TPPII and SIRT6 directly affect glucose metabolism which drive malignant growth. In addition, SIRT6 activators are attractive candidates for Alzheimer's disease (AD) due to the protection effect of SIRT6 overexpression from DNA damage. TPPII activity exhibits a decreasing effect on mTOR signaling, and its requirement for the degradation of Abeta peptides in the human fibroblasts suggests that it has dual functions in tumorigenesis and AD-related pathology. Likewise, the direct promotion of the invasiveness of breast epithelial cells and the contribution to the Abeta degradation by stimulating the matrix metalloproteinases production suggest a double functional role for CD147. An association of the partial portion of cellular CD147 to gamma-secretase further supports the functional relation to AD pathology. The animal and cellular models with downregulated or knockout TPPII, p53, SIRT6, SIRT7, and MYBBP1A expression levels illustrate similar functions of the interacting proteins. They demonstrate similar effects on the length of life span, premature aging, and lipid metabolism. The presented protein interaction network is relevant to the discoveries of the mechanisms of tumorigenesis, aging, and neurodegeneration. PMID- 27699590 TI - High-fructose diet is as detrimental as high-fat diet in the induction of insulin resistance and diabetes mediated by hepatic/pancreatic endoplasmic reticulum (ER) stress. AB - In the context of high human consumption of fructose diets, there is an imperative need to understand how dietary fructose intake influence cellular and molecular mechanisms and thereby affect beta-cell dysfunction and insulin resistance. While evidence exists for a relationship between high-fat-induced insulin resistance and metabolic disorders, there is lack of studies in relation to high-fructose diet. Therefore, we attempted to study the effect of different diets viz., high-fat diet (HFD), high-fructose diet (HFS), and a combination (HFS + HFD) diet on glucose homeostasis and insulin sensitivity in male Wistar rats compared to control animals fed with normal pellet diet. Investigations include oral glucose tolerance test, insulin tolerance test, histopathology by H&E and Masson's trichrome staining, mRNA expression by real-time PCR, protein expression by Western blot, and caspase-3 activity by colorimetry. Rats subjected to high fat/fructose diets became glucose intolerant, insulin-resistant, and dyslipidemic. Compared to control animals, rats subjected to different combination of fat/fructose diets showed increased mRNA and protein expression of a battery of ER stress markers both in pancreas and liver. Transcription factors of beta-cell function (INSIG1, SREBP1c and PDX1) as well as hepatic gluconeogenesis (FOXO1 and PEPCK) were adversely affected in diet-induced insulin resistant rats. The convergence of chronic ER stress towards apoptosis in pancreas/liver was also indicated by increased levels of CHOP mRNA & increased activity of both JNK and Caspase-3 in rats subjected to high-fat/fructose diets. Our study exposes the experimental support in that high-fructose diet is equally detrimental in causing metabolic disorders. PMID- 27699592 TI - Revisiting Rossion and Pourtois with new ratings for automated complexity, familiarity, beauty, and encounter. AB - Differences between norm ratings collected when participants are asked to consider more than one picture characteristic are contrasted with the traditional methodological approaches of collecting ratings separately for image constructs. We present data that suggest that reporting normative data, based on methodological procedures that ask participants to consider multiple image constructs simultaneously, could potentially confounded norm data. We provide data for two new image constructs, beauty and the extent to which participants encountered the stimuli in their everyday lives. Analysis of this data suggests that familiarity and encounter are tapping different image constructs. The extent to which an observer encounters an object predicts human judgments of visual complexity. Encountering an image was also found to be an important predictor of beauty, but familiarity with that image was not. Taken together, these results suggest that continuing to collect complexity measures from human judgments is a pointless exercise. Automated measures are more reliable and valid measures, which are demonstrated here as predicting human preferences. PMID- 27699593 TI - Biodegradable starch derivatives with tunable charge density-synthesis, characterization, and transfection efficiency. AB - Regioselective oxidation of water-soluble starch and conversion with alkyl diamines resulted in defined cationic starch derivatives. Those were assessed in their potential for polyplex formation, biocompatibility, and transfection efficacy. The new polymers have the advantage of being biodegradable, being not cytotoxic at rather high concentrations (LC50 > 400 MUg/ml) for C2 substitution, and reach transfection efficiencies comparable to commercial transfection reagents. The polymer with the highest transfection efficacy is a C12 substituted polymer (degree of substitution = 30 %) at N/P 3. The LC50 value of that highly modified polymer is still one order of magnitude lower than that of PEI 25 kDa. PMID- 27699595 TI - Alcohol Use and Food Insecurity Among People Living with HIV in Mbarara, Uganda and St. Petersburg, Russia. AB - Food insecurity (FI) is a documented problem associated with adverse health outcomes among HIV-infected populations. Little is known about the relationship between alcohol use and FI. We assessed whether heavy alcohol use was associated with FI among HIV-infected, antiretroviral therapy (ART)-naive cohorts in Uganda and Russia. Inverse probability of treatment weighted logistic regression models were used to evaluate the association using cross-sectional baseline data. FI was experienced by half of the Russia cohort (52 %) and by a large majority of the Uganda cohort (84 %). We did not detect an association between heavy alcohol use and FI in either cohort (Russia: AOR = 0.80, 95 % CI 0.46, 1.40; Uganda: AOR = 1.00, 95 % CI 0.57, 1.74) or based on the overall combined estimate (AOR = 0.89, 95 % CI 0.60, 1.33). Future studies should explore the determinants of FI in HIV infected populations to inform strategies for its mitigation. PMID- 27699596 TI - The Interaction of Risk Network Structures and Virus Natural History in the Non spreading of HIV Among People Who Inject Drugs in the Early Stages of the Epidemic. AB - This article explores how social network dynamics may have reduced the spread of HIV-1 infection among people who inject drugs during the early years of the epidemic. Stochastic, discrete event, agent-based simulations are used to test whether a "firewall effect" can arise out of self-organizing processes at the actor level, and whether such an effect can account for stable HIV prevalence rates below population saturation. Repeated simulation experiments show that, in the presence of recurring, acute, and highly infectious outbreaks, micro-network structures combine with the HIV virus's natural history to reduce the spread of the disease. These results indicate that network factors likely played a significant role in the prevention of HIV infection within injection risk networks during periods of peak prevalence. They also suggest that social forces that disturb network connections may diminish the natural firewall effect and result in higher rates of HIV. PMID- 27699594 TI - Objective Measurement of Inaccurate Condom Use Reporting Among Women Using Depot Medroxyprogesterone Acetate for Contraception. AB - Observational analyses have suggested that women using the injectable contraceptive depot medroxyprogesterone acetate (DMPA) may have heightened risk of acquiring HIV. However, those analyses were potentially confounded by sexual behavior, with possible differential condom use and reporting by women using DMPA versus no contraception. In a cross-sectional study, we measured the presence of a biomarker of recent condomless sex (Y chromosomal [Yc] DNA) in vaginal swabs from HIV-uninfected African women who had an HIV-infected partner and reported 100 % condom use. Half of the samples tested were from women reporting DMPA and half were from women using no contraception. Among 428 specimens tested (213 from DMPA users and 215 from women using no contraception), 32.0 % had Yc DNA detected, with a mean of 193 copies/10,000 human cells (range 0.1-8201). The frequency of detection did not differ by contraceptive use: 34.2 % of DMPA users versus 29.8 % of women using no contraception, adjusted odds ratio 1.3 (95 % confidence interval 0.9-2.0). These results suggest that inaccurate reporting of condom use by DMPA users may not account for the heightened risk of HIV acquisition among DMPA users in some observational studies. PMID- 27699597 TI - Food Security Status is Related to Mental Health Quality of Life Among Persons Living with HIV. AB - This study evaluated the association between health related quality of life and food security among persons living with HIV (PLHIV). We studied 167 PLHIV who completed questionnaires assessing food security, disease symptomatology, and several domains of the SF-36 health related quality of life survey. HIV disease state was assessed from medical records. Associations between independent and outcome variables were determined through linear regression models. Compared to food security, very low food security was significantly associated with lower mental component summary scores, [average difference -4.98 (95 % CI -9.85, 0.10)]; mental health, [average difference -5.44 (95 % CI -10.08, -0.81)]; and general health, [average difference -5.13 (95 % CI -9.65, -0.65)] after adjusting for covariates. About a fourth of participants experienced severe food insecurity, which negatively influenced their mental health and general wellbeing. The inclusion of resources for food assistance in HIV treatment programs may help ameliorate mental health challenges faced by PLHIV. PMID- 27699598 TI - Ischemic Post-Conditioning Induces Post-Stroke Neuroprotection via Hsp70-Mediated Proteasome Inhibition and Facilitates Neural Progenitor Cell Transplantation. AB - In view of the failure of pharmacological therapies, alternative strategies promoting post-stroke brain repair are needed. Post-conditioning is a potentially promising therapeutic strategy, which induces acute neuroprotection against ischemic injury. To elucidate longer lasting actions of ischemic post conditioning, mice were exposed to a 60-min stroke and post-conditioning by an additional 10-min stroke that was induced 10 min after reperfusion onset. Animals were sacrificed 24 h or 28 days post-stroke. Post-conditioning reduced infarct volume and neurological deficits 24 h post-stroke, enhancing blood-brain barrier integrity, reducing brain leukocyte infiltration, and reducing oxidative stress. On the molecular level, post-conditioning yielded increased Hsp70 expression, whereas nuclear factor (NF)-kappaB and proteasome activities were decreased. Reduced infarct volume and proteasome inhibition were reversed by Hsp70 knockdown, suggesting a critical role of the Hsp70 proteasome pathway in ischemic post-conditioning. The survival-promoting effects of ischemic post-conditioning, however, were not sustainable as neuroprotection and neurological recovery were lost 28 days post-stroke. Although angioneurogenesis was not increased by post conditioning, the favorable extracellular milieu facilitated intracerebral transplantation of neural progenitor cells 6 h post-stroke, resulting in persisted neuroprotection and neurological recovery. Thus, post-conditioning might support brain repair processes, but in view of its transient, neuroprotection is unlikely useful as stroke therapy in its current form. PMID- 27699600 TI - The Motor KIF5C Links the Requirements of Stable Microtubules and IGF-1 Receptor Membrane Insertion for Neuronal Polarization. AB - Three early signals of asymmetry have been described to occur in a single neurite of neurons at stage 2 of differentiation (before polarization) and shown to be essential for neuronal polarization: (i) accumulation of stable microtubules, (ii) enrichment of the plasma membrane with activatable IGF-1r, and (iii) polarized transport of the microtubular motor KIF5C. Here, we studied the possible relationship between these three phenomena. Our results show that the activatable (membrane-inserted) IGF-1r and stable microtubules accumulate in the same neurite of cells at stage 2. The polarized insertion of IGF-1r depends on microtubule dynamics as shown using drugs which modify microtubule stability. Silencing of KIF5C expression prevents the polarized insertion of IGF-1r into the neuronal plasmalemma and neuronal polarization. Syntaxin 6 and VAMP4, necessary for the polarized insertion of the IGF-1r, are associated to vesicles carried by the microtubular motor KIF5C and is transported preferentially to the neurite where KIF5C accumulates. We conclude that the enrichment of stable microtubules in the future axon enhances KIF5C-mediated vesicular transport of syntaxin 6 and VAMP4, which in turn mediates the polarized insertion of IGF-1r in the plasmalemma, a key step for neuronal polarization. We herewith establish a mechanistic link between three early polarity events necessary for the establishment of neuronal polarity. PMID- 27699601 TI - Generation of a Functional Human Neural Network by NDM29 Overexpression in Neuroblastoma Cancer Cells. AB - Recent advances in life sciences suggest that human and rodent cell responses to stimuli might differ significantly. In this context, the results achieved in neurotoxicology and biomedical research practices using neural networks obtained from mouse or rat primary culture of neurons would benefit of the parallel evaluation of the same parameters using fully differentiated neurons with a human genetic background, thus emphasizing the current need of neuronal cells with human origin. In this work, we developed a human functionally active neural network derived by human neuroblastoma cancer cells genetically engineered to overexpress NDM29, a non-coding RNA whose increased synthesis causes the differentiation toward a neuronal phenotype. These cells are here analyzed accurately showing functional and morphological traits of neurons such as the expression of neuron-specific proteins and the possibility to generate the expected neuronal current traces and action potentials. Their morphometrical analysis is carried out by quantitative phase microscopy showing soma and axon sizes compatible with those of functional neurons. The ability of these cells to connect autonomously forming physical junctions recapitulates that of hippocampal neurons, as resulting by connect-ability test. Lastly, these cells self-organize in neural networks able to produce spontaneous firing, in which spikes can be clustered in bursts. Altogether, these results show that the neural network obtained by NDM29-dependent differentiation of neuroblastoma cells is a suitable tool for biomedical research practices. PMID- 27699599 TI - Linagliptin, a Dipeptidyl Peptidase-4 Inhibitor, Mitigates Cognitive Deficits and Pathology in the 3xTg-AD Mouse Model of Alzheimer's Disease. AB - Glucagon-like peptide-1 (GLP-1) is an incretin hormone shown to be active in the treatment of type-2 diabetes (T2D) and has also been shown as efficacious in Alzheimer's disease (AD). Dipeptidyl peptidase-4 (DPP-4), an enzyme that is expressed in numerous cells, rapidly inactivates endogenous GLP-1. Therefore, DPP 4 inhibition is employed as a therapeutic avenue to increase GLP-1 levels in the management of T2D. The effectiveness of DPP-4 inhibitors in the treatment of AD has been reported in various animal models of AD. With this background, the present study was designed to examine the effectiveness of linagliptin, a DPP-4 inhibitor in the 3xTg-AD mouse model of Alzheimer's disease. Nine-month-old 3xTg AD mice were administered linagliptin orally (5, 10, and 20 mg/kg) for 8 weeks. At the end of the linagliptin treatment, mice were evaluated for cognitive ability on the Morris Water Maze and Y-maze. Following cognitive evaluation, mice were sacrificed to determine the effect of the linagliptin on brain incretin levels, amyloid burden, tau phosphorylation, and neuroinflammation. We confirm that linagliptin treatment for 8 weeks mitigates the cognitive deficits present in 3xTg-AD mice. Moreover, linagliptin also improves brain incretin levels and attenuates amyloid beta, tau phosphorylation as well as neuroinflammation. In conclusion, linagliptin possesses neuroprotective properties that may be attributed to the improvement of incretin levels in the brain. PMID- 27699602 TI - Tauroursodeoxycholic Acid Protects Against Mitochondrial Dysfunction and Cell Death via Mitophagy in Human Neuroblastoma Cells. AB - Mitochondrial dysfunction has been deeply implicated in the pathogenesis of several neurodegenerative diseases. Thus, to keep a healthy mitochondrial population, a balanced mitochondrial turnover must be achieved. Tauroursodeoxycholic acid (TUDCA) is neuroprotective in various neurodegenerative disease models; however, the mechanisms involved are still incompletely characterized. In this study, we investigated the neuroprotective role of TUDCA against mitochondrial damage triggered by the mitochondrial uncoupler carbonyl cyanide m-chlorophelyhydrazone (CCCP). Herein, we show that TUDCA significantly prevents CCCP-induced cell death, ROS generation, and mitochondrial damage. Our results indicate that the neuroprotective role of TUDCA in this cell model is mediated by parkin and depends on mitophagy. The demonstration that pharmacological up-regulation of mitophagy by TUDCA prevents neurodegeneration provides new insights for the use of TUDCA as a modulator of mitochondrial activity and turnover, with implications in neurodegenerative diseases. PMID- 27699603 TI - C-Terminal Binding Protein is Involved in Promoting to the Carcinogenesis of Human Glioma. AB - C-terminal binding protein (CtBP) is responsible for regulating the pathogenesis of a lot of cancer types. However, whether CtBP1/2 is involved in regulating the growth and development of human glioma is still obscure. In the present study presented here, our results firstly reveal that CtBP1/2 deficiency, induced by siRNA interference, disrupts the functional integrity of the MRN complex that is responsible for DNA repair in human glioma cells. The dysfunction of the MRN complex further contributes to the up-regulation of ATM and Rad3-related kinase (ATR) and Chk1 signaling pathway, which inhibits cell cycle progression mediated by CDK2, preparing for the initiation of DNA repair. Under the condition of hypoxia, hypoxia-inducible factor-1alpha (HIF-1alpha) can be directly regulated by CDK2 on protein level, playing coordinately regulatory role in the carcinogenesis of human glioma cells. Overall, our findings reveal that CtBP1/2 is essential to promote to human glioma cell growth through maintaining the DNA stability regulated by the MRN/ATR/Chk1/CDK2/HIF-1alpha signaling pathway. PMID- 27699604 TI - Epigenetic Regulation of SNAP25 Prevents Progressive Glutamate Excitotoxicty in Hypoxic CA3 Neurons. AB - Exposure to global hypoxia and ischemia has been reported to cause neurodegeneration in the hippocampus with CA3 neurons. This neuronal damage is progressive during the initial phase of exposure but maintains a plateau on prolonged exposure. The present study on Sprague Dawley rats aimed at understanding the underlying molecular and epigenetic mechanisms that lead to hypoxic adaptation of CA3 neurons on prolonged exposure to a global hypoxia. Our results show stagnancy in neurodegeneration in CA3 region beyond 14 days of chronic exposure to hypobaria simulating an altitude of 25,000 ft. Despite increased synaptosomal glutamate and higher expression of NR1 subunit of NMDA receptors, we observed decrease in post-synaptic density and accumulation of synaptic vesicles at the pre-synaptic terminals. Molecular investigations involving western blot and real-time PCR showed duration-dependent decrease in the expression of SNAP-25 resulting in reduced vesicular docking and synaptic remodeling. ChIP assays for epigenetic factors showed decreased expression of H3K9Ac and H3K14Ac resulting in SNAP-25 promoter silencing during prolonged hypoxia. Administration of sodium butyrate, a non-specific HDAC inhibitor, during 21 days hypoxic exposure prevented SNAP-25 downregulation but increased CA3 neurodegeneration. This epigenetic regulation of SNAP-25 promoter was independent of increased DNMT3b expression and promoter methylation. Our findings provide a novel insight into epigenetic factors-mediated synaptic remodeling to prevent excitotoxic neurodegeneration on prolonged exposure to global hypobaric hypoxia. PMID- 27699606 TI - Long-term changes in subfoveal choroidal thickness and central macula thickness after Nd:YAG laser capsulotomy. AB - PURPOSE: To evaluate changes in central macula thickness (CMT), subfoveal choroid thickness (SCT), and intraocular pressure (IOP) before and after neodymium:yttrium-aluminum-garnet (Nd:YAG) laser capsulotomy. METHODS: 42 eyes of 42 patients who underwent Nd:YAG laser capsulotomy were included in this prospective study. CMT, SCT, and IOP were evaluated preoperatively and at postoperative week 1 and postoperative months 1, 3, 6, and 12. RESULTS: CMT was 238.1 +/- 27.6 MUm (mean +/- SD) preoperatively, then 239.7 +/- 29.8, 241.3 +/- 28.7, 242.7 +/- 27.2, 238.8 +/- 23.7, and 238.3 +/- 21.7 MUm at postoperative week 1 and months 1, 3, 6, and 12, respectively. SCT was 263.3 +/- 21.6 MUm preoperatively, and 265.5 +/- 24.8, 266.2 +/- 25.7, 267.1 +/- 26.3, 269.1 +/- 24.2, and 269.9 +/- 21.4 MUm at postoperative week 1 and months 1, 3, 6, and 12, respectively. There were no significant differences between preoperative and postoperative results for CMT, SCT, or IOP (all p > 0.05). CONCLUSION: Although there were slight changes in choroid thickness in the long term, treatment of posterior capsule opacification with a low-energy Nd:YAG laser is a safe procedure that increases visual acuity without creating a significant increase in IOP, CMT, and SCT. PMID- 27699605 TI - Femtosecond laser-assisted LASIK versus PRK for high myopia: comparison of 18 month visual acuity and quality. AB - PURPOSE: To compare 18-month outcomes between femtosecond laser-assisted LASIK (femto-LASIK) and photorefractive keratectomy with mitomycin-C (PRK-MMC) for myopia of more than 7.0 D in terms of visual acuity and quality. METHODS: In this comparative nonrandomized clinical trial, 60 eyes from 30 patients (30 eyes in each group) were enrolled. The two procedures were compared in terms of 18-month changes in uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction spherical equivalent, ocular and corneal higher order aberrations (HOAs), and contrast sensitivity (CS). RESULTS: Mean myopia was -8.65 +/- 1.51 and -8.04 +/- 1.70 D (P = 0.149) and mean ablation depth was 109.37 +/- 9.07 and 105.09 +/- 12.59 um (P = 0.138), in the femto-LASIK and PRK-MMC groups, respectively. Baseline parameters were not significantly different between the two groups (all P > 0.05). At 18 months postoperatively, 75 % in the femto-LASIK, versus 57.1 % in the PRK-MMC group, had 20/20 UDVA (P = 0.017). CDVA remained similarly unchanged in both groups (P = 0.616). No case had residual refractive error more than 1.0 D in the femto-LASIK group, while 33.5 % in the other group had more than 1.0 D residual error (P = 0.390). Changes in corneal HOA were not significantly different between the two groups (P = 0.260). Cases in the femto-LASIK group showed more increase in ocular HOA (P = 0.032) and coma (P = 0.083, power = 72 %). CS remained similarly unchanged in all spatial frequencies in both groups (all P > 0.05). CONCLUSION: Although femto-LASIK induces more HOA compared to PRK-MMC, considering outcomes in terms of 20/20 UDVA, residual refractive error, and CS stability, femto-LASIK provides more favorable results than PRK-MMC in high myopia. PMID- 27699607 TI - To assess the efficacy of vertical muscle surgery for management of hypotropia in monocular elevation deficiency type II. AB - AIM: To assess the efficacy of vertical muscle surgery for management of hypotropia in monocular elevation deficiency (MED) type II. Knapp's is described as standard procedure for management of MED type II. However, it is not graded and has unpredictable amount of correction. Besides this, there is drift towards overcorrection with time and limitation of movements in extreme adduction and abduction. MED is a vertical misalignment for which vertical muscle surgery is also described but limited literature is available. METHODS: Thirteen fresh cases of MED type II with hypotropia >20 PD and age >4 years were included in our interventional study. All cases underwent superior rectus resection and inferior rectus recession (vertical R&R) depending upon amount of preoperative deviation. Success was defined as hypotropia <5 PD at 1-year follow-up. RESULTS: Twelve patients (92.30 %) were aligned to within 5 PD. Six patients (46.15 %) had gain in elevation. Bell's phenomenon was improved in six patients (46.15 %). There was no limitation in down gaze in any patient. None gained stereopsis. CONCLUSION: Vertical R&R is a good alternative for MED type II with predictable amount of correction especially in patients with higher preoperative deviation. It spares horizontal muscles for correction of any associated horizontal deviation. PMID- 27699608 TI - Sarcopenia as a Novel Preoperative Prognostic Predictor for Survival in Patients with Bladder Cancer Undergoing Radical Cystectomy. AB - PURPOSE: To investigate the prognostic significance of sarcopenia on long-term outcomes in patients with bladder cancer after radical cystectomy (RC). METHODS: We retrospectively reviewed 136 patients undergoing RC for urothelial carcinoma at our institution. Prognostic impact of the preoperative clinical, laboratory, and radiologic parameters were evaluated by Cox proportional hazard model analyses, and a nomogram was developed to predict cancer-specific survival (CSS) after RC. RESULTS: The mean follow-up was 46.7 months. Patients with sarcopenia had a significantly shorter CSS than those without sarcopenia. On univariate Cox analysis, clinical T stage, histology of transurethral resection of bladder tumor (TURBT) specimen, pretreatment hemoglobin, pretreatment neutrophil-to-lymphocyte ratio (NLR), pretreatment serum C-reactive protein level, pretreatment serum albumin level, presence of hydronephrosis, and presence of sarcopenia were associated with significantly worse CSS. On multivariate Cox stepwise analysis, sarcopenia (hazard rate [HR] = 2.3, p = 0.015), clinical T stage (cT4: HR = 5.3; p = 0.0096), presence of hydronephrosis (HR = 2.0; p = 0.033), histology of TURBT specimen (HR = 2.2, p = 0.044), and NLR (HR = 1.3; p = 0.0048) were significant independent predictors of an unfavorable prognosis Based on the results of the multivariate analysis, we developed a nomogram to predict 1-, 3-, and 5-year CSS after RC. CONCLUSIONS: Sarcopenia, clinical T stage, presence of hydronephrosis, histology of TURBT specimen, and NLR are novel preoperative prognostic factors even after adjustment for other known preoperative predictors in patients undergoing RC for bladder cancer. PMID- 27699609 TI - Preoperative Serum Carcinoembryonic Antigen Level as a Prognostic Factor for Recurrence and Survival After Curative Resection Followed by Adjuvant Chemotherapy in Stage III Colon Cancer. AB - BACKGROUND: Carcinoembryonic antigen (CEA) is the most widely used tumor marker in colon cancer; however, there has been controversy regarding the significance of preoperative serum CEA level as a prognostic factor for recurrence. In this study, we evaluated the optimal cutoff value and prognostic significance of preoperative serum CEA level in stage III colon cancer. METHODS: Based on a retrospective cohort of 965 patients with stage III colon cancer who underwent elective curative surgery and adjuvant chemotherapy with fluoropyrimidine and oxaliplatin (training set), we determined the optimal cutoff value of CEA for recurrence using the Contal and O'Quigley method. We assessed the prognostic value of this cutoff value in terms of disease-free survival (DFS) and overall survival (OS) in a prospective cohort of 268 patients with stage III colon cancer (validation set). A Cox proportional hazards model was used to explore the association of prognostic variables with DFS and OS. RESULTS: The statistically determined best cutoff value for CEA was 3 ng/mL in the training set. A high CEA level (>=3 ng/mL) was associated with inferior DFS (hazard ratio [HR] 4.609, 95 % confidence interval [CI] 2.028-10.474) and OS (HR 3.956, 95 % CI 1.127-13.882) in the validation set, while multivariate analysis showed that a high CEA level was an independent risk factor for DFS and OS in both study subsets. CONCLUSION: Preoperative serum CEA level is an independent prognostic factor for DFS and OS in patients with stage III colon cancer after curative resection and adjuvant chemotherapy.

AB - BACKGROUND: Short-course radiotherapy with delayed surgery (SRT-delay) is still under clinical investigation for its efficacy in treating low rectal cancer (<=5 cm from the anal verge). This study was designed to assess the pattern of local recurrence and oncologic outcomes in T3 low rectal cancer treated with SRT-delay. METHODS: This study enrolled T3 low rectal cancer patients without distant metastasis between 2003 and 2015. All patients received total mesorectal excision following SRT-delay (25 Gy/10 fractions/5 days + S-1 radiosensitizer with a 4 week delay of surgery). The median follow-up period was 69 (range 1-149) months. RESULTS: A total 119 consecutive patients had low rectal cancer; 104 (87.4 %) underwent intersphincteric resection (ISR), and 15 (12.6 %) underwent abdominoperineal resection (APR). Fifty-six patients (47.1 %) were ypT downstaged, 86 (72.2 %) were ypN0, and 10 (8.4 %) had circumferential resection margin involvement. The 5-year local recurrence-free survival, recurrence-free survival, and overall survival were 93.0, 76.2, and 80.5 %, respectively. Nine patients experienced local recurrence: lateral pelvic recurrence in six patients (5.0 %) and central pelvic recurrence in three (2.5 %). CONCLUSIONS: A total of 87.4 % of sphincter-preserving surgeries were performed for T3 low rectal cancer following SRT-delay. Pathological tumor downstaging, circumferential resection margin involvement, local recurrence, and oncologic outcomes were acceptable; therefore, the SRT-delay regimen may be an option for treating T3 low rectal cancer. PMID- 27699611 TI - Robotic Right Colectomy with Modified Complete Mesocolic Excision: Long-Term Oncologic Outcomes. AB - BACKGROUND: A modified complete mesocolic excision (mCME) technique for the treatment of right-sided colon cancer recently was shown by Hohenberger and colleagues to provide impressive long-term oncologic outcomes. This report aims to describe the authors' experience with robotic right colectomy using mCME. The safety, feasibility, and efficacy of this procedure are measured by complications, conversion rates, and 4-year oncologic outcomes. METHODS: A retrospective study analyzed 100 consecutive patients who underwent robotic right colectomy with mCME and intracorporeal anastomosis at the authors' institution between November 2005 and November 2013. Intra- and postoperative clinical outcomes, pathologic data, and survival were analyzed. RESULTS: Robotic right colectomy with mCME was successfully performed for all the patients. No conversions or intraoperative complications occurred. The major complication rate (Dindo 3 or 4) was 4 %. During a median follow-up period of 48.5 months (range 24 114 months), the survival rates were 94.5 % for disease-specific survival, 91.4 % for disease-free survival, and 90.3 % for overall survival. CONCLUSIONS: The authors' experience confirms the feasibility and safety of mCME for the treatment of right-sided colon cancer. This technique provided satisfying short-term outcomes with promising 4-year oncologic results. However, the real benefits of the CME technique should be evaluated further by well-conducted randomized studies before its adoption in routine practice is recommended.

AB - Hsc70 is the constitutively expressed mammalian heat shock 70 kDa (Hsp70) cytosolic chaperone. It plays a central role in cellular proteostasis and protein trafficking. Here, we present the backbone and methyl group assignments for the 386-residue nucleotide binding domain of the human protein. This domain controls the chaperone's allostery, binds multiple co-chaperones and is the target of several classes of known chemical Hsp70 inhibitors. The NMR assignments are based on common triple resonance experiments with triple labeled protein, and on several 15N and 13C-resolved 3D NOE experiments with methyl-reprotonated samples. A combination of computer and manual data interpretation was used. PMID- 27699617 TI - Backbone and side-chain resonance assignments of Plasmodium falciparum SUMO. AB - One of the most debilitating diseases Malaria, in its different forms, is caused by protozoan of Plasmodium species. Deadliest among these forms is the "cerebral malaria" which is afflicted upon by Plasmodium falciparum. Plasmodium adopts numerous strategies including various post-translational modifications (PTMs) to infect and survive in the human host. These PTMs have proven their critical requirement in the Plasmodium biology. Recently, sumoylation has been characterized as one of the important PTMs and many of its putative substrates have been identified in Plasmodium. Sumoylation is the covalent attachment of SUMO protein to the substrate protein, which is mediated by an enzyme cascade involving activating (E1), conjugating (E2), and ligating enzymes (E3). Here, we report resonance assignment for 1H, 13C and 15N of Plasmodium falciparum SUMO (Pf SUMO) protein determined by various 2D and 3D heteronuclear NMR experiments along with predicted secondary structures. PMID- 27699618 TI - Implementation of a Multidisciplinary Guideline for Low Back Pain: Process Evaluation Among Health Care Professionals. AB - Background To reduce the burden of low back pain (LBP) in the Netherlands, a multidisciplinary guideline for LBP has been implemented in Dutch primary care using a multifaceted implementation strategy targeted at health care professionals (HCPs) and patients. The current paper describes the process evaluation of the implementation among HCPs. Methods The strategy aimed to improve multidisciplinary collaboration and communication, and consisted of 7 components. This process evaluation was performed using the Linnan and Steckler framework. Data were collected using a mixed methods approach of quantitative and qualitative data. Results 128 HCPs participated in the implementation study, of which 96 participated in quantitative and 21 participated in qualitative evaluation. Overall dose delivered for this study was 89 %, and the participants were satisfied with the strategy, mostly with the multidisciplinary approach, which contributed to the mutual understanding of each other's disciplines and perspectives. While the training sessions did not yield any new information, the strategy created awareness of the guideline and its recommendations, contributing to positively changing attitudes and aiding in improving guideline adherent behaviour. However, many barriers to implementation still exist, including personal and practical factors, confidence, dependence and distrust issues among the HCPs, as well as policy factors (e.g. reimbursement systems). Conclusions The data presented in this paper have shown that the strategy that was used to implement the guideline in a Dutch primary care setting was feasible, especially when using a multidisciplinary approach. However, identified barriers for implementation have been identified and should be addressed in future implementation.

AB - Lung cancer is the major cause of death among patients with cancer worldwide. This work is intended to develop a methodology for the diagnosis of lung nodules using images from the Image Database Consortium and Image Database Resource Initiative (LIDC-IDRI). The proposed methodology uses image processing and pattern recognition techniques. To differentiate the patterns of malignant and benign forms, we used a Minkowski functional, distance measures, representation of the vector of points measures, triangulation measures, and Feret diameters. Finally, we applied a genetic algorithm to select the best model and a support vector machine for classification. In the test stage, we applied the proposed methodology to 1405 (394 malignant and 1011 benign) nodules from the LIDC-IDRI database. The proposed methodology shows promising results for diagnosis of malignant and benign forms, achieving accuracy of 93.19 %, sensitivity of 92.75 %, and specificity of 93.33 %. The results are promising and demonstrate a good rate of correct detections using the shape features. Because early detection allows faster therapeutic intervention, and thus a more favorable prognosis for the patient, herein we propose a methodology that contributes to the area. PMID- 27699620 TI - Influence of Early Onset of Alcohol Use on the Development of Adolescent Alcohol Problems: a Longitudinal Binational Study. AB - This study examined cross-national similarities in a developmental model linking early age of alcohol use onset to frequent drinking and heavy drinking and alcohol problems 1 and 2 years later in a binational sample of 13-year-old students from two states: Washington State, USA and Victoria, Australia (N = 1833). A range of individual, family, school, and peer influences was included in analyses to investigate their unique and shared contribution to development of early and more serious forms of alcohol use and harms from misuse. Data were collected annually over a 3-year period from ages 13 to 15. Analyses were conducted using multiple-group structural equation modeling. For both states, early use of alcohol predicted frequent drinking, which predicted alcohol problems. Family protective influences had neither direct effects on heavy drinking nor effects on alcohol harm in either state, whereas school protection directly reduced the risk of heavy drinking in both states. Exposure to antisocial peers and siblings predicted a higher likelihood of heavy drinking and alcohol harm for students in both Washington and Victoria. Implications for the prevention of adolescent alcohol problems are discussed. PMID- 27699623 TI - Clinical Pharmacokinetics and Pharmacodynamics of Insulin Glargine 300 U/mL. AB - Concentrated insulin analogs have recently been approved and are available for clinical use in the management of diabetes mellitus. One new product is insulin glargine U-300 (Sanofi), a basal concentrated insulin of 300 U/mL. Several studies have been conducted and completed evaluating blood samples for the pharmacokinetics of insulin glargine U-300 and euglycemic clamp procedures for the pharmacodynamics. This concentrated insulin has a low within-day variability and high day-to-day reproducibility, allowing for a more constant and prolonged duration of action, compared with insulin glargine U-100 (100 U/mL). Insulin glargine U-300 is equally effective, when compared with insulin glargine U-100 for glycemic control in patients with type 1 and 2 diabetes mellitus. Insulin glargine U-300 has a similar efficacy profile to insulin glargine U-100 for glycemic control, yet with lower rates of nocturnal and severe hypoglycemia. Insulin glargine U-300 can be considered an acceptable basal insulin for patients with type 1 and 2 diabetes mellitus, and it has a potential role among patients who are naive to insulin therapy or require titration of basal insulin. Titration of insulin glargine U-300 would result in less volume and a lower risk of hypoglycemia, compared with insulin glargine U-100. This article evaluates and summarizes the pharmacokinetics and pharmacodynamics of insulin glargine U-300, for patients with type 1 or 2 diabetes mellitus, and summarizes its application to clinical practice. PMID- 27699624 TI - Time to Progression of Pancreatic Cancer: Evaluation with Multi-Detector Computed Tomography. AB - PURPOSE: The aim of this study is to evaluate the natural history of untreated pancreatic cancer, with a particular emphasis on the growth rate of primary tumor and development of metastatic disease. METHODS: One hundred patients with histologically proven pancreatic ductal adenocarcinoma examined with at least two CT scans with no intervening treatment were included. Tumor diameters and volumes were measured in CT scans and tumor growth rates and volume doubling times (VDTs) were calculated. The relationship between initial tumor size, growth rate, and distant metastasis development were investigated. RESULTS: Included tumors were 1.0-6.2 cm (mean, 2.9 +/- 1.3 cm) in diameter and 5.5-1225.9 cm3 (mean, 120.6 +/- 158.9 cm3) in volume at the initial CT. Tumor growth rates were -0.4 to 19.9 cm/year (mean, 4.2 +/- 3.8 cm/year) in diameter, and 11.1-13,321.5 cm3/year (mean, 727.8 +/- 1609.5 cm3/year) in volume corresponding to VDT of 20.0-976.8 days (mean, 132.3 +/- 132.1 days). The growth rate was significantly associated with the initial diameter and volume (p < 0.001). The development of distant metastasis was significantly associated with initial diameter (p < 0.05), volume (p = 0.015), and volume growth rate (p = 0.002). CONCLUSIONS: The growth rate and VDTs of untreated pancreatic cancers varied widely, from less than a month to more than 4 years, positively associated with tumor size. The small tumors tend to grow slowly and have low risk for developing metastasis. PMID- 27699622 TI - A Two-Way Steady-State Pharmacokinetic Interaction Study of Doravirine (MK-1439) and Dolutegravir. AB - INTRODUCTION: Doravirine, a non-nucleoside reverse-transcriptase inhibitor in development for the treatment of patients with human immunodeficiency virus-1 infection, has potential to be used concomitantly in antiretroviral therapy with dolutegravir, an integrase strand transfer inhibitor. The pharmacokinetic interactions between these drugs were therefore assessed. METHODS: Oral formulations of doravirine and dolutegravir were dosed both individually and concomitantly once daily in healthy adults. Twelve subjects (six were male), 23 42 years of age, were enrolled and 11 completed this phase I, open-label, three period, fixed-sequence study per protocol; one subject was discontinued for a positive cotinine test at admission to period 2. In period 1, dolutegravir 50 mg was administered for 7 days. After a 7-day washout, doravirine 200 mg was dosed for 7 days in period 2, followed (without washout) by both doravirine and dolutegravir simultaneously for 7 days in period 3. Plasma samples were taken to determine dolutegravir and doravirine concentrations. RESULTS: The steady-state concentration 24 h post-dose (C24) of dolutegravir was not substantially altered by co-administration of doravirine multiple doses; area under the plasma concentration-time curve from dosing to 24 h post-dose (AUC0-24), maximum concentration (C max), and C24 geometric mean ratios were 1.36, 1.43, and 1.27, respectively. The pharmacokinetics of doravirine was not affected by multiple doses of dolutegravir (geometric mean ratios: 1.00, 0.98, and 1.06 for AUC0-24, C24, and C max, respectively). Both drugs were generally well tolerated. CONCLUSION: The results of this study demonstrate that concomitant administration of doravirine and dolutegravir in healthy subjects causes no clinically significant alteration in the pharmacokinetic and safety profiles of the two drugs, thereby supporting further evaluation of co-administration of these agents for human immunodeficiency virus-1 treatment. PMID- 27699626 TI - Marijuana Use and Dependence in Chilean Adolescents and Its Association with Family and Peer Marijuana Use. AB - PURPOSE: The purpose of the study is to examine (1) whether family and peer marijuana use are independently related to adolescent marijuana use in Chile, (2) whether family and peer marijuana use are associated with adolescent marijuana dependence in adolescents using marijuana, and (3) whether the adolescent's age moderates the association between family or peer use and adolescent marijuana use and/or dependence. METHOD: This study used data from the National Survey on Drug Use in the General Population in Chile (a cross-sectional observational study), which was conducted in 2008 and 2010 in 4413 adolescents aged 12-19. Adolescents answered questions about their past-year marijuana use and dependence (ICD-10 criteria) and the marijuana use of their family and peers. Logistic regressions were performed while controlling for confounders. RESULTS: Adolescents who had a family member who used marijuana were five times more likely to use the drug. Adolescents with a close friend who used marijuana were eight times more likely to use marijuana. When adolescents were using marijuana, they were three times more likely to be dependent if they had a family member who used the drug. However, no significant relationship was found between peer use and dependence. No statistically significant interactions were found between family or peer use and age. CONCLUSION: Family and peer marijuana use was independently associated with adolescent's past-year marijuana use; however, only family marijuana use was statistically associated with adolescent's marijuana dependence. PMID- 27699625 TI - Cannabinoids and GI Disorders: Endogenous and Exogenous. AB - OPINION STATEMENT: Despite the political and social controversy affiliated with it, the medical community must come to the realization that cannabinoids exist as a ubiquitous signaling system in many organ systems. Our understanding of cannabinoids and how they relate not only to homeostasis but also in disease states must be furthered through research, both clinically and in the laboratory. The identification of the cannabinoid receptors in the early 1990s have provided us with the perfect target of translational research. Already, much has been done with cannabinoids and the nervous system. Here, we explore the implications it has for the gastrointestinal tract. Most therapeutics currently on the market presently target only one aspect of the cannabinoid system. Our main purpose here is to highlight areas of research and potential avenues of discovery that the cannabinoid system has yet to reveal. PMID- 27699627 TI - The Association Between Social Support, Body Mass Index and Increased Risk of Prediabetes: the Cardiovascular Risk in Young Finns Study. AB - PURPOSE: The psychosocial determinants of prediabetes are poorly understood. The aims of our study were (1) to analyse the association between perceived social support in young adulthood and fasting glucose levels and prediabetes in mid adulthood in a cohort of healthy Finns, (2) to explore whether body mass index (BMI), inflammation or depression mediate this relationship, (3) and to examine the association between social support trajectory groups and fasting glucose. METHOD: A prospective design was used with an analytic sample of 1250 participants aged 3-18 years at baseline (1980) and aged 12-39 years when social support was measured. Fasting glucose and prediabetes were assessed 32 years after baseline. Linear and logistic regression was used to examine the association between social support and the outcome measures. A bootstrapping technique was used to examine mediation effects. RESULTS: Social support was associated with future glucose levels in women after adjusting for childhood socioeconomic status (SES) and youth depression (beta = -0.136, p = 0.001) and also predicted prediabetes in women after adjusting for childhood SES (beta = 1.31, 95 % CI 1.02 to 1.69, p = 0.031). Both associations were attenuated after adjusting for BMI in mid-adulthood. BMI was found to mediate the relationship between social support and prediabetes in women (beta for indirect effect beta = 0.09, SE = 0.03, CI = 0.03 to 0.16). CONCLUSION: Low perceived social support in young adulthood is associated with high fasting glucose and prediabetes in mid adulthood in women but not men. The association between social support and prediabetes in women can be partly explained by BMI. PMID- 27699629 TI - Genetic Screening in Pheochromocytoma/Paraganglioma. PMID- 27699628 TI - Issues Arising in Psychological Consultations to Help Parents Talk to Minor and Young Adult Children about their Cancer Genetic Test Result: a Guide to Providers. AB - The defining difference between genetic and traditional medicine is that genetic findings have implications not just for the patient, but also for their relatives. Discussion of a test result between parent and child is both a transformative and a translational moment in the life of a family. Parents report wanting help in talking to their children. The challenge for genetic counselors and other providers is to be able to recognize which issues are at the core of parental distress and be able to offer recommendations to empower and support parents. The complexity of potential genetic findings, including variants of uncertain significance (VUS) and incidental findings have vastly increased, requiring considerable explanation and leaving less time for discussion of emotional issues. While the nature of the testing (single gene to multigene panel and genomic testing) is dramatically changing, the nature of parent concerns remains remarkably constant. Families differ in many respects, so no "recipe" suffices to answer parents' questions about how this important task should be approached in each family. Successful consultation to parents requires true counseling, matching parents' fears and questions with information, exploration and advice specific to their concerns, their circumstances and strengths.

AB - BACKGROUND: Demand for total hip arthroplasty (THA) is high and expected to continue to grow during the next decade. Although much of this growth includes working-aged patients, cost-effectiveness studies on THA have not fully incorporated the productivity effects from surgery. QUESTIONS/PURPOSES: We asked: (1) What is the expected effect of THA on patients' employment and earnings? (2) How does accounting for these effects influence the cost-effectiveness of THA relative to nonsurgical treatment? METHODS: Taking a societal perspective, we used a Markov model to assess the overall cost-effectiveness of THA compared with nonsurgical treatment. We estimated direct medical costs using Medicare claims data and indirect costs (employment status and worker earnings) using regression models and nonparametric simulations. For direct costs, we estimated average spending 1 year before and after surgery. Spending estimates included physician and related services, hospital inpatient and outpatient care, and postacute care. For indirect costs, we estimated the relationship between functional status and productivity, using data from the National Health Interview Survey and regression analysis. Using regression coefficients and patient survey data, we ran a nonparametric simulation to estimate productivity (probability of working multiplied by earnings if working minus the value of missed work days) before and after THA. We used the Australian Orthopaedic Association National Joint Replacement Registry to obtain revision rates because it contained osteoarthritis specific THA revision rates by age and gender, which were unavailable in other registry reports. Other model assumptions were extracted from a previously published cost-effectiveness analysis that included a comprehensive literature review. We incorporated all parameter estimates into Markov models to assess THA effects on quality-adjusted life years and lifetime costs. We conducted threshold and sensitivity analyses on direct costs, indirect costs, and revision rates to assess the robustness of our Markov model results. RESULTS: Compared with nonsurgical treatments, THA increased average annual productivity of patients by USD 9503 (95% CI, USD 1446-USD 17,812). We found that THA increases average lifetime direct costs by USD 30,365, which were offset by USD 63,314 in lifetime savings from increased productivity. With net societal savings of USD 32,948 per patient, total lifetime societal savings were estimated at almost USD 10 billion from more than 300,000 THAs performed in the United States each year. CONCLUSIONS: Using a Markov model approach, we show that THA produces societal benefits that can offset the costs of THA. When comparing THA with other nonsurgical treatments, policymakers should consider the long-term benefits associated with increased productivity from surgery.

AB - Approximately 50 % of HIV-1 seropositive individuals develop HIV-1 associated neurocognitive disorders (HAND), which commonly include alterations in executive functions, such as inhibition, set shifting, and complex problem solving. Executive function deficits in HIV-1 are fairly well characterized, however, relatively few studies have explored the elemental dimensions of neurocognitive impairment in HIV-1. Deficits in temporal processing, caused by HIV-1, may underlie the symptoms of impairment in higher level cognitive processes. Translational measures of temporal processing, including cross-modal prepulse inhibition (PPI), gap-prepulse inhibition (gap-PPI), and gap threshold detection, were studied in mature (ovariectomized) female HIV-1 transgenic (Tg) rats, which express 7 of the 9 HIV-1 genes constitutively throughout development. Cross-modal PPI revealed a relative insensitivity to the manipulation of interstimulus interval (ISI) in HIV-1 Tg animals in comparison to control animals, extending previously reported temporal processing deficits in HIV-1 Tg rats to a more advanced age, suggesting the permanence of temporal processing deficits. In gap PPI, HIV-1 Tg animals exhibited a relative insensitivity to the manipulation of ISI in comparison to control animals. In gap-threshold detection, HIV-1 Tg animals displayed a profound differential sensitivity to the manipulation of gap duration. Presence of the HIV-1 transgene was diagnosed with 91.1 % accuracy using gap threshold detection measures. Understanding the generality and permanence of temporal processing deficits in the HIV-1 Tg rat is vital to modeling neurocognitive deficits observed in HAND and provides a key target for the development of a diagnostic screening tool. PMID- 27699633 TI - Antibody-Based Drugs and Approaches Against Amyloid-beta Species for Alzheimer's Disease Immunotherapy. AB - Alzheimer's disease (AD), one of the most devastating diseases for the older population, has become a major healthcare burden in the increasingly aging society worldwide. Currently, there are still only symptomatic treatments available on the market, just to slow down disease progression. In the past decades, extensive research focusing on the development of immunotherapy using monoclonal antibodies (mAbs) as potential "disease-modifying drugs" has shown promise in inhibiting or clearing the formation of toxic amyloid-beta (Abeta) species, the suspected causative agents of AD. As a result, these potential life saving drugs can break the amyloid cascade, cease neurodegeneration, and prevent further reduction in cognitive and physical function. In this review, we first describe the polymorphisms of Abeta species, comprising three different pools, including monomers, soluble oligomers, and insoluble fibrils, with each pool encompassing multiple structures of Abeta aggregation. A comprehensive review on their toxicities follows in relation to the characterized epitopes of anti-Abeta mAb candidates under development. We then present the outcomes of these mAbs in clinical or pre-clinical trials and conclude by providing a summary of other novel and promising antibody-based immunotherapeutic approaches that deserve more attention for the effective treatment of AD in the future. PMID- 27699635 TI - Optimizing CT technique to reduce radiation dose: effect of changes in kVp, iterative reconstruction, and noise index on dose and noise in a human cadaver. AB - For assessment of the effect of varying the peak kilovoltage (kVp), the adaptive statistical iterative reconstruction technique (ASiR), and automatic dose modulation on radiation dose and image noise in a human cadaver, a cadaver torso underwent CT scanning at 80, 100, 120 and 140 kVp, each at ASiR settings of 0, 30 and 50 %, and noise indices (NIs) of 5.5, 11 and 22. The volume CT dose index (CTDIvol), image noise, and attenuation values of liver and fat were analyzed for 20 data sets. Size-specific dose estimates (SSDEs) and liver-to-fat contrast-to noise ratios (CNRs) were calculated. Values for different combinations of kVp, ASiR, and NI were compared. The CTDIvol varied by a power of 2 with kVp values between 80 and 140 without ASiR. Increasing ASiR levels allowed a larger decrease in CTDIvol and SSDE at higher kVp than at lower kVp while image noise was held constant. In addition, CTDIvol and SSDE decreased with increasing NI at each kVp, but the decrease was greater at higher kVp than at lower kVp. Image noise increased with decreasing kVp despite a fixed NI; however, this noise could be offset with the use of ASiR. The CT number of the liver remained unchanged whereas that of fat decreased as the kVp decreased. Image noise and dose vary in a complicated manner when the kVp, ASiR, and NI are varied in a human cadaver. Optimization of CT protocols will require balancing of the effects of each of these parameters to maximize image quality while minimizing dose. PMID- 27699634 TI - Use of a C1 Inhibitor Concentrate in Adults >=65 Years of Age with Hereditary Angioedema: Findings from the International Berinert(r) (C1-INH) Registry. AB - BACKGROUND: Treatment of hereditary angioedema (HAE) in 'older adults' (those aged >=65 years) has not been well studied. The international Berinert Patient Registry collected data on the use of intravenous plasma-derived, pasteurized, nanofiltered C1-inhibitor concentrate (pnfC1-INH; Berinert(r)/CSL Behring) in patients of any age, including many older adults. METHODS: This observational registry, conducted from 2010 to 2014 at 30 US and seven European sites, gathered prospective (post-enrollment) and retrospective (pre-enrollment) usage and adverse event (AE) data on subjects treated with pnfC1-INH. RESULTS: The registry documented 1701 pnfC1-INH infusions in 27 older adults. A total of 1511 HAE attacks treated with pnfC1-INH administration were reported among 25 of the 27 (92.6 %) older adults. Among the older adults, mean (standard deviation [SD]) (8.8 [4.1] IU/kg) and median (6.4 IU/kg) pnfC1-INH doses were lower than those reported for 252 'younger adults' (those aged <65 years: 12.9 [6.2], 12.5 IU/kg, respectively). A total of 19 AEs occurred in 8 of 23 (34.8 %) older adults with prospective data, for rates of 0.83 events per subject and 0.02 events per infusion, similar to corresponding rates in younger adults (0.91 and 0.03, respectively). None of the AEs were considered related to pnfC1-INH, and all but two events (prostatectomy, gastrointestinal bleeding) were mild or moderate in severity. Administration of pnfC1-INH outside of a healthcare setting was reported for 1609 infusions in 16 older adults, representing 94.6 % of all pnfC1 INH infusions in this age group. There were no recorded instances of difficulty with self-administration of intravenous pnfC1-INH. CONCLUSIONS: These findings suggest a high degree of safety with intravenous pnfC1-INH use in older adults with HAE, regardless of administration setting. Trial Registration Clinicaltrials.gov NCT01108848. PMID- 27699636 TI - Relation between one- and two-dimensional noise power spectra of magnetic resonance images. AB - Our purpose in this study was to elucidate the relation between the one dimensional (1D) and two-dimensional (2D) noise power spectra (NPSs) in magnetic resonance imaging (MRI). We measured the 1D NPSs using the slit method and the radial frequency method. In the slit method, numerical slits 1 pixel wide and L pixels long were placed on a noise image (128 * 128 pixels) and scanned in the MR image domain. We obtained the 1D NPS using the slit method (1D NPS_Slit) and the 2D NPS of the noise region scanned by the slit (2D NPS_Slit). We also obtained 1D NPS using the radial frequency method (1D NPS_Radial) by averaging the NPS values on the circumference of a circle centered at the origin of the original 2D NPS. The properties of the 1D NPS_Slits varied with L and the scanning direction in PROPELLER MRI. The 2D NPS_Slit shapes matched that of the original 2D NPS, but were compressed by L/128. The central line profiles of the 2D NPS_Slits and the 1D NPS_Slits matched exactly. Therefore, the 1D NPS_Slits reflected not only the NPS values on the central axis of the original 2D NPS, but also the NPS values around the central axis. Moreover, the measurement precisions of the 1D NPS_Slits were lower than those of the 1D NPS_Radial. Consequently, it is necessary to select the approach applied for 1D NPS measurements according to the data acquisition method and the purpose of the noise evaluation.

AB - Maternal prenatal psychological symptoms are associated with child health outcomes, e.g., atopic diseases. Altered prenatal functioning of the immune system is a potential mechanism linking maternal symptoms with child health. Research on prenatal distress and cytokines is warranted. The study population comprised consecutive N = 139 women from a general population-based FinnBrain Birth Cohort Study. Standardized questionnaires for depressive, overall anxiety, and pregnancy-related anxiety symptoms were used. Serum concentrations of selected cytokines were analyzed using Multiplex bead arrays from samples drawn at the gestational week 24. The concentrations of T helper (Th)2-related interleukins (IL)-9 and IL-13 and Th1-related IL-12 correlated positively with prenatal depressive and overall anxiety symptom scores (p values, range 0.011 0.029). Higher interferon (IFN)-gamma/IL-4 ratio (p = 0.039) and Th2-related IL-5 (p = 0.007) concentration correlated positively with depressive symptoms. Pregnancy-related anxiety score correlated positively with IL-12 (p = 0.041), IL 13 (p = 0.025), and anti-inflammatory IL-10 (p = 0.048) concentrations. IL-6 and TNF-alpha concentrations were unrelated to prenatal symptoms. As a novel finding, we observed positive correlations between concentrations of potentially proallergenic cytokines and maternal prenatal psychological symptoms. Different symptom measures may yield distinct cytokine responses. This provides hypotheses for studies on mechanisms bridging prenatal stress and child health.

AB - We report a case of irritable bowel syndrome (IBS), diarrhea subtype, characterized by daily 'morning rush' and episodic acute exacerbations brought on by common IBS trigger foods including insoluble fiber, red wine and large/rich meals. The patient also had a history of migraine headaches, and a family history suggesting a common diathesis for both disorders. Given hypothesized contributions to IBS from dysregulation of the enteric serotonergic system, a trial of low-dose triptan medication was implemented in the context of the patient's known IBS triggers, with highly satisfactory results.

AB - Syphilis is a widespread infection with increasing frequency in developed countries, especially among men who have sex with men. We present two cases of oropharyngeal syphilis in two middle-aged men who presented with a painless tonsillar ulcer and progressive enlargement of cervical lymph nodes suspected of being a tonsillar tumour. A pathologic analysis of the ulcer led to an accurate diagnosis. We review the imaging and pathologic findings to emphasize the importance of taking syphilis into account in the differential diagnosis.

AB - A 3-monthly formulation of intramuscular paliperidone palmitate (3-monthly paliperidone palmitate) has recently been approved for the maintenance treatment of schizophrenia in adult patients in the EU (Trevicta(r)), following earlier approval in the USA (Invega Trinza(r)). This narrative review discusses the clinical use of 3-monthly paliperidone palmitate in the maintenance treatment of schizophrenia in adult patients and summarizes its pharmacological properties. The efficacy of the 3-monthly paliperidone palmitate formulation as a maintenance treatment for schizophrenia has been demonstrated in well designed, phase III trials. Three-monthly paliperidone palmitate was more effective than placebo in delaying time to relapse and reducing relapse rates, and was noninferior to 1 monthly paliperidone palmitate in the proportion of patients that remained relapse-free. The 3-monthly formulation was also more effective than placebo in controlling the symptoms of schizophrenia, whilst not differing significantly from the 1-monthly formulation in terms of symptomatic control. Three-monthly paliperidone palmitate was generally well tolerated in clinical trials, with a tolerability profile consistent with that of the 1-monthly formulation. In conclusion, 3-monthly paliperidone palmitate is a useful treatment option for adult patients with schizophrenia who are adequately treated with the 1-monthly formulation, particularly for those who would prefer, or may benefit from, longer dosing intervals.

AB - Recently, several medical treatments for ulcerative colitis (UC) have been developed, including 5-aminosalicylic acids (5-ASAs), corticosteroids, thiopurine, calcineurin inhibitors, and anti-tumor necrosis factor (TNF) alpha treatments. Treatment options including calcineurin inhibitors and anti-TNF treatment for refractory UC are discussed in this article. Furthermore, upcoming treatments are introduced, such as golimumab, vedolizumab, AJM300, tofacitinib. Budesonide foamwill be used as one treatment option in patients with distal colitis. Herbal medicine, such as Qing-Dai is also effective for active UC and may be useful for patients who are refractory to anti-TNFalpha treatments. In the near future, physicians will able to use many different treatments for UC patients. However, we should not forget 5-ASA and corticosteroids as the fundamental treatments for UC patients.

AB - Circadian rhythms are a collection of endogenously driven biochemical, physiological, and behavioral processes that oscillate in a 24-h cycle and can be entrained by external cues. Circadian clock molecules are responsible for the expression of regulatory components that modulate, among others, the cell's metabolism and energy consumption. In clinical practice, the regulation of clock mechanisms is relevant to biotransformation of therapeutics. Accordingly, xenobiotic metabolism and detoxification, the two processes that directly influence drug effectiveness and toxicity, are direct manifestations of the daily oscillations of the cellular and biochemical processes taking place within the gastrointestinal, hepatic/biliary, and renal/urologic systems. Consequently, the impact of circadian timing should be factored in when developing therapeutic regimens aimed at achieving maximum efficacy, minimum toxicity, and decreased adverse effects in a patient. However, and despite a strong mechanistic foundation, only 0.16 % of ongoing clinical trials worldwide exploit the concept of 'time-of-day' administration to develop safer and more effective therapies. In this article, we (1) emphasize points of control at which circadian biology intersects critical processes governing treatment interventions; (2) explore the extent to which chronotherapeutics are incorporated into clinical trials; (3) recognize roadblocks; and (4) recommend approaches to precipitate the integration of chronobiological concepts into clinical practice. PMID- 27699648 TI - Clinical and Cost Effectiveness of Apixaban Compared to Aspirin in Patients with Atrial Fibrillation: An Australian Perspective. AB - OBJECTIVE: To determine the clinical and cost effectiveness of apixaban compared to aspirin in the prevention of thromboembolic events for patients with atrial fibrillation for whom vitamin K antagonist (VKA) therapy (warfarin) has been considered unsuitable. METHODS: A previously published Markov model with yearly cycles was updated. Information from the Apixaban Versus Acetylsalicylic acid to prevent Stroke in Atrial Fibrillation (AVERROES) trial in combination with other population data was used to simulate the costs and effects of apixaban compared to aspirin over 10 years. The model comprised five health states. Costs from an Australian healthcare perspective were estimated from published sources for the year 2015. The main outcome of interest was number needed to treat (NNT), number needed to harm (NNH), the incremental cost-effectiveness ratio (ICER) [cost per quality-adjusted life-year (QALY) gained, and cost per year of life saved (YoLS)]. Costs and benefits were discounted at 5.0 % per annum. RESULTS: For each patient followed up over 10 years, NNT to prevent one additional event (thromboembolic event, death) for apixaban compared to aspirin was 4.6 and 11.8, respectively. NNH was 35.9 for non-fatal major bleeding. The model predicted that compared to aspirin, apixaban would lead to 0.33 YoLS (discounted) and 0.29 QALYs gained (discounted), at an incremental cost of AUD$1996 (discounted). This resulted in ICERs of AUD$6011 per YoLS and AUD$6929 per QALY gained. In the sensitivity analyses, ICERs were most sensitive to efficacy measures derived from the AVERROES study, and time frame. CONCLUSION: Compared to aspirin, apixaban is likely to be cost effective in preventing thromboembolic disease among VKA unsuitable patients with atrial fibrillation.

However, it is a double-edged sword, as it functions in both clearance of infection and inflammatory damage. It is therefore important that innate immune responses are tightly controlled to prevent harmful excessive inflammation. Nuclear receptors (NRs) are a family of transcription factors that play critical roles in various physiological responses. Orphan NRs are a subset of NRs for which the ligands and functions are unclear. Accumulating evidence has revealed that orphan NRs play essential roles in innate immune responses to prevent pathogenic inflammatory responses and to enhance antimicrobial host defenses. In this review, we describe current knowledge on the roles and mechanisms of orphan NRs in the regulation of innate immune responses. Discovery of new functions of orphan NRs would facilitate development of novel preventive and therapeutic strategies against human inflammatory diseases. PMID- 27699649 TI - A new supramolecular based liquid solid microextraction method for preconcentration and determination of trace bismuth in human blood serum and hair samples by electrothermal atomic absorption spectrometry. AB - A simple and reliable supramolecule-aggregated liquid solid microextraction method is described for preconcentration and determination of trace amounts of bismuth in water as well as human blood serum and hair samples. Catanionic microstructures of cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) surfactants, dissolved in deionized water/propanol, are used as a green solvent to extract bismuth (III)-diethyldithiocarbamate complexes by dispersive microextraction methodology. The extracted solid phase is easily removed and dissolved in 50 MUL propanol for subsequent measurement by electrothermal atomic absorption spectrometry (ET-AAS). The procedure benefits the merits of supramolecule aggregates' properties and dispersive microextraction technique using water as the main component of disperser solvent, leading to direct interaction with analyte. Phase separation behavior of extraction solvent and different parameters influencing the extraction efficiency of bismuth ion such as salt concentration, pH, centrifugation time, amount of chelating agent, SDS:CTAB mole ratio, and solvent amounts were thoroughly optimized. Under the optimal experimental conditions, the calibration curve was linear in the range of 0.3-6 MUg L-1 Bi (III) with a limit of detection (LOD) of 0.16 MUg L-1 (S/N = 3). The relative standard deviations (RSD) of determination were obtained to be 5.1 and 6.2 % for 1 and 3 MUg L-1 of Bi (III), respectively. The developed method was successfully applied as a sensitive and accurate technique for determination of bismuth ion in human blood serum, hair samples, and a certified reference material.

AB - Food industries are increasingly oriented toward new foods to improve nutritional status and/or to combat nutritional deficiency diseases. In this context, silicon biofortification could be an innovative tool for obtaining new foods with possible positive effects on bone mineralization. In this paper, an alternative and quick in vitro approach was applied in order to evaluate the potential health promoting effects of five silicon-biofortified leafy vegetables (tatsoi, mizuna, purslane, Swiss chard and chicory) on bone mineralization compared with a commercial silicon supplement. The silicon bioaccessibility and bioavailability of the five leafy vegetables (biofortified or not) and of the supplement were assessed by applying a protocol consisting of in vitro gastrointestinal digestion coupled with a Caco-2 cell model. Silicon bioaccessibility ranged from 0.89 to 8.18 mg/L and bioavailability ranged from 111 to 206 MUg/L of Si for both vegetables and supplement. Furthermore, the bioavailable fractions were tested on a human osteoblast cell model following the expression of type 1 collagen and alkaline phosphatase. The results obtained highlighted that the bioavailable fraction of biofortified purslane and Swiss chard improved the expression of both osteoblast markers compared with the supplement and other vegetables. These results underline the potentially beneficial effect of biofortified leafy vegetables and also indicate the usefulness of in vitro approaches for selecting the best vegetable with positive bone effects for further in vivo research. PMID- 27699651 TI - Expression analysis of the endogenous Zscan4 locus and its coding proteins in mouse ES cells and preimplantation embryos. AB - Mouse Zinc finger and SCAN domain containing 4 (Zscan4) is encoded in multiple copies of Zscan4 genes, which are expressed in late two-cell stage preimplantation embryos and in 1-5% of the embryonic stem (ES) cell population at a given time. Due to the highly identical nucleotide sequences of multiple copies of Zscan4 paralogs and pseudogenes in the mouse Zscan4 genomic cluster, previous analyses have been done using exogenous transgenes under the regulation of Zscan4c promoter. In this manuscript, we generated knock-in mouse ES cell lines and mouse lines, in which the expression of endogenous Zscan4c, one of the Zscan4 genes, can be specifically monitored with a green fluorescent protein variant, Emerald. Interestingly, we found that only ~30% of Zscan4-immunopositive ES cells were Emerald positive, suggesting that even when the Zscan4 locus is active, not all Zscan4 genes are expressed synchronously. We also carried out mass spectrometry of protein complexes associated with endogenous Zscan4 proteins. Taken together, our genetic engineering at an endogenous Zscan4c gene provides the first clue for the expression and function of each gene copy of Zscan4 locus in a physiological context. PMID- 27699652 TI - Insulin-like growth factor 1 regulation of proliferation and differentiation of Xenopus laevis myogenic cells in vitro. AB - To understand the mechanism of muscle remodeling during Xenopus laevis metamorphosis, we examined the in vitro effect of insulin-like growth factor 1 (IGF-1) on growth and differentiation of three different-fate myogenic cell populations: tadpole tail, tadpole dorsal, and young adult leg muscle. IGF-1 promoted growth and differentiation of both tail and leg myogenic cells only under conditions where these cells could proliferate. Inhibition of cell proliferation by DNA synthesis inhibitor cytosine arabinoside completely canceled the IGF-1's cell differentiation promotion, suggesting the possibility that IGF 1's differentiation-promotion effect is an indirect effect via IGF-1's cell proliferation promotion. IGF-1 promoted differentiation dose dependently with maximum effect at 100-500 ng/ml. RT-PCR analysis revealed the upregulation (11 fold) of ifg1 mRNA expression in developing limbs, suggesting that IGF-1 plays a role in promoting muscle differentiation during limb development. The combined effect of triiodo-L-thyronine (T3) and IGF-1 was also examined. In adult leg cells, IGF-1 promoted growth and differentiation irrespective of the presence of T3. In larval tail cells, cell count was 76% lower in the presence of T3, and IGF 1 did not promote proliferation and differentiation in T3-containing medium. In larval dorsal cells, cell count was also lower in the presence of T3, but IGF-1 enhanced proliferation and differentiation in T3-containing medium. This result is likely due to the presence among dorsal cells of both adult and larval types (1:1). Thus, IGF-1 affects only adult-type myogenic cells in the presence of T3 and helps accelerate dorsal muscle remodeling during metamorphosis. PMID- 27699653 TI - Zscan4 is expressed specifically during late meiotic prophase in both spermatogenesis and oogenesis. AB - Mouse zinc finger and SCAN domain containing 4 (Zscan4) proteins, which are encoded by multiple copies of Zscan4 genes, are expressed specifically in preimplantation embryos in vivo and embryonic stem (ES) cells in vitro. However, the expression patterns of mouse Zscan4 in vivo have been largely elusive. Here, we show that Zscan4 proteins are expressed in adult ovaries and testes. In ovaries, Zscan4 proteins were detected in germinal vesicle (GV) stage oocytes in antral follicles, indicating that Zscan4 genes are activated during the diplotene/dictyate stage in meiotic prophase I. Remarkably, Zscan4 showed different spatial localization patterns between two distinct GV oocytes, which can be distinguished by global chromatin organization-surrounded nucleolus (SN) and non-surrounded nucleolus (NSN). These spatiotemporal differences in Zscan4 localizations correlated with the transition of RNA polymerase II-mediated transcriptional status during GV oocyte maturation. In testes, Zscan4 proteins were detected in spermatocytes at late pachytene/diplotene stages and in Sertoli cells. These results suggest that Zscan4 may play critical roles during late meiotic prophase in both males and females. PMID- 27699655 TI - Serum level of neopterin is not a marker of disease activity in treated rheumatoid arthritis patients. AB - Neopterin has been measured in many autoimmune diseases and was reported as a marker of cellular immunity activation in rheumatoid asthritis (RA). The aim of this work was to assess serum neopterin as a marker of disease activity in treated RA patients. We measured serum level of neopterin in 120 treated RA patients and 100 age- and sex-matched controls by high-performance liquid chromatography (HPLC) method, and disease activity score was calculated in all patients by DAS28-CRP score. Significantly higher levels of neopterin were observed in RA patients (11.46 +/- 3.56 nmol/L) compared to healthy controls (4.74 +/- 1.98 nmol/L), P < 0.0001. Significantly higher neopterin levels were observed among male RA patients [median (IQR), 13.44 (12.65-16.21)] than female RA patients [median (IQR), 11.86 (7.91-13.44)], P <0.0001. No significant correlations between neopterin and age, age of disease onset, disease duration, or any of the disease activity parameters were found. Moreover, no significant difference regarding neopterin levels in different disease activity phases was identified. Our results indicated that neopterin is a marker of RA but not a marker of disease activity in treated RA patients. PMID- 27699654 TI - In vitro reprogramming of rat bmMSCs into pancreatic endocrine-like cells. AB - Islet transplantation provides curative treatments to patients with type 1 diabetes, but donor shortage restricts the broad use of this therapy. Thus, generation of alternative transplantable cell sources is intensively investigated worldwide. We previously showed that bone marrow-derived mesenchymal stem cells (bmMSCs) can be reprogrammed to pancreatic-like cells through simultaneously forced suppression of Rest/Nrsf (repressor element-1 silencing transcription factor/neuronal restrictive silencing factor) and Shh (sonic hedgehog) and activation of Pdx1 (pancreas and duodenal transcription factor 1). We here aimed to reprogram bmMSCs further along the developmental pathway towards the islet lineages by improving our previous strategy and by overexpression of Ngn3 (neurogenin 3) and NeuroD1 (neurogenic differentiation 1), critical regulators of the development of endocrine pancreas. We showed that compared to the previous protocol, the overexpression of only Pdx1 and Ngn3 reprogrammed bmMSCs into cells with more characteristics of islet endocrine lineages verified with bioinformatic analyses of our RNA-Seq datasets. These analyses indicated 2325 differentially expressed genes including those involved in the pancreas and islet development. We validated with qRT-PCR analysis selective genes identified from the RNA-Seq datasets. Thus, we reprogrammed bmMSCs into islet endocrine-like cells and advanced the endeavor to generate surrogate functional insulin-secreting cells. PMID- 27699656 TI - Dichotomous versus semi-quantitative scoring of ultrasound joint inflammation in rheumatoid arthritis using novel individualized joint selection methods. AB - The aim of the study is to compare the responsiveness of two joint inflammation scoring systems (dichotomous scoring (DS) versus semi-quantitative scoring (SQS)) using novel individualized ultrasound joint selection methods and existing ultrasound joint selection methods. Responsiveness measured by the standardized response means (SRMs) using the DS and the SQS system (for both the novel and existing ultrasound joint selection methods) was derived using the baseline and the 3-month total inflammatory scores from 20 rheumatoid arthritis patients. The relative SRM gain ratios (SRM-Gains) for both scoring system (DS and SQS) comparing the novel to the existing methods were computed. Both scoring systems (DS and SQS) demonstrated substantial SRM-Gains (ranged from 3.31 to 5.67 for the DS system and ranged from 1.82 to 3.26 for the SQS system). The SRMs using the novel methods ranged from 0.94 to 1.36 for the DS system and ranged from 0.89 to 1.11 for the SQS system. The SRMs using the existing methods ranged from 0.24 to 0.32 for the DS system and ranged from 0.34 to 0.49 for the SQS system. The DS system appears to achieve high responsiveness comparable to SQS for the novel individualized ultrasound joint selection methods. PMID- 27699657 TI - Efficacy of combination DMARD therapy vs. hydroxychloroquine monotherapy in chronic persistent chikungunya arthritis: a 24-week randomized controlled open label study. AB - In a proportion of patients, chikungunya arthritis (CA) might run into a chronic persistent phase. The treatment for this phase is not very clear. In this randomized parallel group open label study of 24 weeks duration, we evaluated the efficacy of DMARD combination in persistent CA. Consecutive 139 patients with persistent CA (persistent arthritis for >1 year after the chikungunya fever either in 2008 or 2009 fulfilling epidemiological criteria for CA) were screened. Of these patients who were already taking hydroxychloroquine (HCQ) and had active arthritis were randomized to receive either fixed-dose combination therapy (methotrexate 15 mg/day, sulfasalazine 1 g/day, and HCQ 400 mg/day) or continue with HCQ 400 mg/day (dose optimized) monotherapy. Both groups received oral prednisolone up to 6 weeks. Assessments at every 4 weeks were carried out for primary efficacy (disease activity score; DAS ESR 28) and secondary efficacies, HAQ-Indian version and pain VAS100mm. Seventy-two patients were randomized (37 combination therapy, 35 monotherapy). Both groups were well matched in all respects. At 24 weeks, the combination therapy group showed significant improvement in both disease activity (mean +/- SD DAS28; 3.39 +/- 0.87 vs. 4.74 +/- 0.65, p < 0.0001) and disability (mean +/- SD HAQ; 1.4 +/- 0.31 vs. 1.88 +/- 0.47, p < 0.0001). At the study end, pain VAS was significantly less in the combination therapy group (46 +/- 6.13 vs. 60.8 +/- 11.6, p < 0.0001). Three patients withdrew from the combination group (inefficacy; 2, adverse event; 1) and seven from monotherapy (inefficacy; 7). This study provide evidence that for chronic persistent CA combination DMARD therapy with methotrexate, sulfasalazine and HCQ is superior to monotherapy with HCQ. PMID- 27699658 TI - Uptake, translocation, and metabolism of hydroxylated and methoxylated polychlorinated biphenyls in maize, wheat, and rice. AB - Hydroxylated polychlorinated biphenyls (OH-PCBs) have been found in the environment with high toxicity. Recently, methoxylated polychlorinated biphenyls (MeO-PCBs) were identified as new pollutants and detected in sewage sludge. This study presents a detailed investigation on the uptake, translocation, and metabolism of OH-PCBs and MeO-PCBs in typical crops including maize, wheat, and rice. The interconversion between OH-PCBs and MeO-PCBs were observed. Demethylation of MeO-PCBs was favored over methylation of OH-PCBs. The metabolites were mainly generated in the roots and then translocated to the shoots. Analog-specific differences showed that the accumulation amounts of MeO PCBs were higher than those of OH-PCBs in the crops. The translocation abilities followed this order: 3'-OH-CB-65 > 4'-OH-CB-101 > 3'-MeO-CB-65 > 4'-MeO-CB-101. The conversion rates were generally higher for 4'-OH-CB-101 than 3'-OH-CB-65 and higher for 4'-MeO-CB-101 than 3'-MeO-CB-65. Interspecies variability among the crops was also observed. The amounts of metabolites and acropetal translocation inside the plants were the greatest for maize. However, the concentration of compounds normalized by the mass of corresponding plant tissue was highest in wheat. These findings provide valuable information for a better understanding of the phytoaccumulation and phytotransformation of OH-PCBs and MeO-PCBs. PMID- 27699659 TI - Biosurfactant-enhanced removal of o,p-dichlorobenzene from contaminated soil. AB - Surfactant-enhanced remediation is less applicable for the treatment of dichlorobenzene (DCB)-contaminated soil. In this study, water solubility enhancements of o-dichlorobenzene (o-DCB) and p-dichlorobenzene (p-DCB) by micellar solutions of biosurfactants (saponin, alkyl polyglycoside) and chemically synthetic surfactant (Tween 80) were measured and compared. Solubilities of o,p-DCB in water were greatly enhanced in a linear fashion by each of Tween 80, saponin, and alkyl polyglycoside. Solubility enhancement efficiencies of surfactants followed the order of Tween 80 > saponin > alkyl polyglycoside. However, the ex situ soil washing experiment demonstrated the opposite result. The removal efficiency of o,p-DCB by biosurfactant saponin and alkyl polyglycoside was higher than that of chemically synthetic surfactant Tween 80 in contaminated soil. This difference may be due to the different adsorption behaviors of the surfactants onto soil. In addition, elution kinetics for o,p-DCB were relatively fast, with apparent elution equilibrium reached within 360 min, and can be described by a pseudo first-order kinetic equation. The elution process of o,p-DCB in soil-aqueous systems obeyed four-parameter biphasic first order kinetic model including rapid and slow phases. The results confirmed potential application of saponin and alkyl polyglycoside in elution solution for enhanced remediation of DCB-contaminated soil.

AB - The occurrence and fate of five endocrine disrupting chemicals (EDCs), including nonylphenol (NP), 4-tert-octylphenol (4-t-OP), 4-tert-butylphenol (4-t-BP), bisphenol A (BPA) and norethindrone (NET) was investigated in four wastewater treatment plants (WWTPs) and receiving river (Suzhou River and Yangtze River) of Shanghai. Selected EDCs in WWTPs influents ranged from 1.02 to 3560 ng L-1, which dominated by NP and BPA. Target compounds detected in effluents were from N.D. to 1136 ng L-1, with NP as most prevalent. The removal rates of target compounds varied from negative of NET to 99 % of BPA. Except of NET, efficiently removal rates (>70 %) were observed in WWTPs. Biological treatment was the major removal stage of selected EDCs in WWTPs. Furthermore, the selected EDCs were detected from N.D. to 424 ng L-1 in receiving river. The correlation analysis suggested EDCs pollution in receiving river might be mainly contributed by WWTPs effluents. The risk quotient of NP (RQ > 1) was higher than any other pollutants, indicating its relatively higher potential risk for the aquatic organism. These results will provide significant background data to future EDCs pollution control and management in Shanghai, China. PMID- 27699662 TI - Imaging the implant-soft tissue interactions in total knee arthroplasty. AB - BACKGROUND: In Total Knee Arthroplasty (TKA), residual pain may be secondary to soft tissue impingements, which are difficult to visualize around chromium-cobalt implants using medical imaging, so their interactions remain poorly understood. The goal of this work was to establish a protocol for in-vitro imaging of the soft tissues around TKA, usable during throughout the range of motion (ROM). METHODS: The full size range of a commercially available TKA prosthesis was manufactured by 3D-printing in non-magnetic and non-radiopaque polymer and implanted in 12 cadaveric knees. The relations between these implants and the soft tissues (Popliteus tendon, Medial and Lateral Collateral Ligament, Patellar and Quadriceps tendons) were analyzed, using MRI (5 embalmed specimens) and CT scans after injection of the tissues with barium-sulfate (3 embalmed and 4 fresh frozen specimens). RESULTS: Both MRI and CT scans enabled good identification of the soft tissues before TKA implantation. MRI produced minimal loss in signal and contrast, and neither the low temperature nor the embalming fluids compromised image quality. CT scans were more precise after TKA implantation, particularly the borders of the implant and the differentiation of soft tissues. Full ROM investigation, manual segmentation and three-dimensional reconstructions were possible only with the CT scan. CONCLUSION: The experimental approach described in this study was successful in visualizing the interactions between the soft tissue and the implants before and after TKA and during the full ROM. The coordinate system allows to localize precisely the different anatomic structures and to quantify any change due to prosthetic implantation. PMID- 27699663 TI - Impact of point mutation P29S in RAC1 on tumorigenesis. AB - A point mutation (P29S) in the RAS-related C3 botulinum toxin substrate 1 (RAC1) was considered to be a trigger for melanoma, a form of skin cancer with highest mortality rate. In this study, we have investigated the pathogenic role of P29S based on the conformational behavior of RAC1 protein toward guanosine triphosphate (GTP). Molecular interaction, molecular dynamics trajectory analysis (RMSD, RMSF, Rg, SASA, DSSP, and PCA), and shape analysis of binding pocket were performed to analyze the interaction energy and the dynamic behavior of native and mutant RAC1 at the atomic level. Due to this mutation, the RAC1 switch I region acquired more flexibility and, to compensate it, the switch II region becomes rigid in their conformational space, as a result of which the interaction energy of the protein for GTP increased. The overall results strongly implied that the changes in atomic conformation of the switch I and II regions in mutant RAC1 protein were a significant reason for its malignant transformation and tumorigenesis. We raised the opportunity for researchers to design possible therapeutic molecule by considering our findings. PMID- 27699664 TI - RIP1 upregulation promoted tumor progression by activating AKT/Bcl-2/BAX signaling and predicted poor postsurgical prognosis in HCC. AB - Although growing body of evidences have identified a critical role for receptor interacting protein kinase 1 (RIP1) in mediating cell death signaling, its possible contribution to hepatocellular carcinoma (HCC) progression remains unclear. Here, we displayed that expression of RIP1 was significantly upregulated in HCC tissues than in adjacent liver tissues from 81.9 % HCC patients (P < 0.001) by immunohistochemistry (IHC) staining. Overexpression of RIP1 was found positively associated with HBV infection, advanced TNM staging, portal vein invasion, and intrahepatic metastases. Kaplan-Meier curve analysis indicated that patients with higher RIP1 expression in HCC tissues suffered from unfavorable postsurgical survival. Higher RIP1 expression in HCC tissues was also confirmed to be an independent poor prognostic predictor. Knockdown of RIP1 resulted in suppression of cell viability and proliferation and induced cell apoptosis in MHCC97h cells. Nevertheless, enforced expression of RIP1 promoted cell viability and proliferation of Huh7 cells and inhibited cell apoptosis. Mechanistic studies revealed that RIP1 exerted its function on HCC progression via activating AKT/Bcl 2/BAX signaling. In conclusion, our results provided the evidence of RIP1 overexpression in HCC, and RIP1 could be a novel predictive factor of unfavorable prognosis in HCC patients. Activation of AKT/Bcl-2/BAX signaling contributed to RIP1 promoting HCC progression.

AB - Paclitaxel (Taxol) is a naturally occurring member of the taxane family of antitumor drugs, which act by stabilizing microtubules. Paclitaxel is inactivated in human liver by a cytochrome P450 (P450)-catalyzed 6alpha-hydroxylation reaction. A reverse-phase, high-performance liquid chromatographic assay is described for the analysis of paclitaxel 6alpha-hydroxylation catalyzed by human liver microsomes or cDNA-expressed P450 enzyme CYP2C8. Analytical separations are achieved using a C18 column with a linear gradient of 10-100% methanol, with detection at 230 nm. This method is applicable to enzymatic studies for determination of CYP2C8-catalyzed paclitaxel 6alpha-hydroxylation activity. PMID- 27699667 TI - Thin-Layer Chromatography Analysis of Human CYP3A-Catalyzed Testosterone 6beta Hydroxylation. AB - Testosterone and other steroid hormones have been studied as prototypic examples of endogenous substrates for hepatic cytochrome P450 (P450) enzymes. CYP3A enzymes from various species, including human, metabolize testosterone by a 6beta hydroxylation reaction, which is unique to this P450 subfamily. A thin-layer chromatographic method is described for the determination of 6beta hydroxytestosterone formed enzymatically by incubation of [14C]-testosterone with cDNA-expressed CYP3A enzymes or liver microsomes. 14C-labeled enzymatic products are applied to silica gel thin-layer plates, which are developed sequentially with methylene chloride:acetone (80:20) followed by chloroform, ethyl acetate, and absolute ethanol (80:20:14). Metabolite quantification is performed by autoradiography and liquid scintillation counting. This method is applicable to enzymatic studies for the determination of CYP3A-dependent testosterone 6beta- hydroxylation activity in both human and animal liver microsomes.

AB - The high resistant rate of Adriamycin (Adr) is associated with a poor prognosis of breast cancer in women worldwide. Since miR-222 might contribute to chemoresistance in many cancer types, in this study, we aimed to investigate its efficacy in breast cancer through PTEN/Akt/p27 kip1 pathway. Firstly, in vivo, we verified that miR-222 was upregulated in chemoresistant tissues after surgery compared with the paired preneoadjuvant samples of 21 breast cancer patients. Then, human breast cancer Adr-resistant cell line (MCF-7/Adr) was constructed to validate the pathway from the parental sensitive cell line (MCF-7/S). MCF-7/Adr and MCF-7/S were transfected with miR-222 mimics, miR-222 inhibitors, or their negative controls, respectively. The results showed that inhibition of miR-222 in MCF-7/Adr significantly increased the expressions of PTEN and p27 kip1 and decreased phospho-Akt (p-Akt) both in mRNA and protein levels (p < 0.05) by using quantitative real-time PCR (qRT-PCR) and western blot. MTT and flow cytometry suggested that lower expressed miR-222 enhanced apoptosis and decreased the IC50 of MCF-7/Adr cells. Additionally, immunofluorescence demonstrated that the subcellular location of p27 kip1 was dislocated resulting from the alteration of miR-222. Conversely, in MCF-7/S transfected with miR-222 mimics, upregulation of miR-222 is associated with decreasing PTEN and p27 kip1 and increasing Akt accompanied by less apoptosis and higher IC50. Importantly, Adr resistance induced by miR-222 overexpression through PTEN/Akt/p27 was completely blocked by LY294002, an Akt inhibitor. Taken together, these data firstly elucidated that miR-222 could reduce the sensitivity of breast cancer cells to Adr through PTEN/Akt/p27 kip1 signaling pathway, which provided a potential target to increase the sensitivity to Adr in breast cancer treatment and further improved the prognosis of breast cancer patients. PMID- 27699668 TI - An Isocratic High-Performance Liquid Chromatography Assay for CYP7A1-Catalyzed Cholesterol 7alpha-Hydroxylation. AB - A normal-phase, isocratic high-performance liquid chromatography assay is described for cholesterol 7alpha-hydroxylation catalyzed by CYP7A1, which corresponds to the first and rate-limiting step in the conversion of cholesterol into bile acids. This method is based on the conversion of the primary cytochrome P450 metabolite, 7alpha-hydroxycholesterol, into 7alpha-hydroxy-4-cholesten-3-one in a reaction catalyzed by exogenous cholesterol oxidase, followed by chromatographic separation with monitoring at 254 nm. This technique is applicable to enzymatic studies for determination of cholesterol 7alpha- hydroxylation activity catalyzed by cDNA-expressed CYP7A1 and animal or human liver microsomes. PMID- 27699669 TI - The Human Cytochrome P450 Allele Nomenclature Committee Web Site : Submission Criteria, Procedures, and Objectives. AB - Interindividual variability in xenobiotic metabolism and drug response is extensive. Genetic factors are predicted to account for 15-30% of this variability in general, but for certain drugs the genetic factor is the major determinant for outcome of drug therapy. Of particular importance for drug metabolism, drug response, and adverse drug reactions are the cytochrome P450 (CYP) enzymes, many of which are polymorphic. An essential basis for research and applications regarding interindividual variability in xenobiotic metabolism and toxicity by polymorphic CYPs is to have a common nomenclature for genetic variants and a system that allows researchers to be rapidly updated within the field. Since 1999 this has been achieved by the operation of the Human Cytochrome P450 Allele Nomenclature Committee Web site ( http://www.imm.ki.se/CYPalleles/ ), where novel allelic variants are published after peer review. Currently, this Web site covers the nomenclature for polymorphic alleles of 22 CYP isoforms including more than 200 functionally different variants. Each CYP has its own Web page, which lists the alleles with their nucleotide changes, their functional consequences, and links to publications where the allele has been identified and characterized. The CYP allele Web site offers a rapid on-line publication of new alleles, provides an overview of peer-reviewed data, and serves as a form of quality control on research on new alleles. PMID- 27699670 TI - Rat Hepatocyte Cultures : Conventional Monolayer and Cocultures With Rat Liver Epithelial Cells. AB - Primary cultures of hepatocytes are useful tools for both short- and long-term pharmacotoxicological research. Under conventional conditions, isolated hepatocytes form a monolayer and survive for about 1 wk but lose some liver specific functions, including xenobiotic biotransformation. In comparison with the conventional monolayer culture model, cocultures with rat liver epithelial cells (RLECs) have an extended life-span and better maintain their drug metabolizing capacity, owing to the presence of cell-cell interactions. In this chapter, techniques for setting up conventional monolayer cultures and cocultures of hepatocytes with RLECs (including isolation, culture, and cryopreservation of RLECs) are described in detail. In addition, comments derived from our own experience are given for successfully culturing primary hepatocytes. PMID- 27699671 TI - Rat Hepatocyte Cultures : Collagen Gel Sandwich and Immobilization Cultures. AB - Mimicking the in vivo microenvironment is one of the current strategies to maintain liver-specific functionality in primary cultured hepatocytes for long periods. Freshly isolated hepatocytes entrapped in collagen gel type I (collagen gel immobilization culture) or sandwiched between two layers of hydrated collagen type I (collagen gel sandwich culture) are known to display liver-specific functions (e.g., biotransformation capacity) for more than 6 wk. We describe how to set up both types of organotypical hepatocyte culture systems. Besides a detailed protocol, we give some practical tips, taken from our own experience with long-term hepatocyte culture. PMID- 27699672 TI - Transfection of Primary Cultures of Rat Hepatocytes. AB - Five different transfection reagents-calcium phosphate, TransFastTM Transfection Reagent, SuperfectTM Transfection Reagent, EffecteneTM Transfection Reagent, and TfxTM-20-were compared for their ability to effectively transfect primary cultures of male rat hepatocytes. Hepatocytes were isolated by the collagenase perfusion method and then cultured on Matrigel-coated plates for 24 h before transfection. The cells were transfected with either pGL3-Control or pGL3-Basic plasmids. The efficiency of transfection of each reagent was monitored using the dual luciferase reporter gene assay system. Superfect Transfection Reagent, Effectene Transfection Reagent and Tfx-20 were the most effective for the transfection of primary hepatocytes and gave comparable transfection efficiencies. Calcium phosphate was found to be the least effective transfection reagent and gave the most variable transfection results. Tfx-20 gave the least variable transfection results when different hepatocyte preparations were compared. PMID- 27699673 TI - Determination of Cellular Localization of Expression of Flavin-Containing Monooxygenase Genes in Mouse Tissues by In Situ Hybridization. AB - Methods are described for the cellular localization of expression of flavin containing monooxygenase (FMO) genes in various mouse tissues by in situ hybridization. These include the production of digoxigenin (DIG)-labeled antisense and sense RNA probes by transcription from FMO cDNA templates, the preparation of paraffin wax-embedded and cryostat tissue sections, the hybridization of RNA probes to tissue sections, and the specific detection of hybridized probes using an antibody to DIG. PMID- 27699674 TI - Deletion of Genes From the Mouse Genome Using Cre/loxP Technology. AB - The steps required to delete genes from the mouse genome are illustrated by showing how a cluster of three flavin-containing monooxygenase (Fmo) genes (Fmo1, Fmo2, and Fmo4) were deleted from mouse chromosome 1. Such large deletions are accomplished using loxP/Cre recombinase technology. Genomic clones corresponding to the genes to be deleted are first isolated, and then appropriate genomic fragments are cloned into vectors containing a loxP site. This produces targeting vectors, which are electroporated into mouse embryonic stem (ES) cells to allow a homologous recombination event to take place between the mouse genomic fragment, present within the vector, and the homologous sequences in the ES cell genome. Screening of ES cells for recombinants in which loxP sites have been inserted on either side of the gene cluster to be deleted is described. Recombination by Cre recombinase to produce ES cell lines carrying the deletion on chromosome 1 is also described.

Successful injection and implantation of blastocysts will produce mice of mixed coat color (the chimera). Also described are methods to establish the success of blastocyst injection and implantation of germ-line transmission of the knockout (KO) mutation. Breeding strategies to produce congenic and isogenic KO mouse lines are outlined. Simple methods for the isolation of tail DNA, the tagging of mice, and record keeping of the line are also given.

AB - A general procedure for the solubilization of cytochrome P450 (P450) from bacterial membranes specifically for a human P450 expressed heterologously in the host Escherichia coli is described. The example involves the use of a P450 (3A4) with a C-terminal oligohistidine tag and includes sequential DEAE and metal affinity chromatography. PMID- 27699678 TI - Expression of Recombinant Flavin-Containing Monooxygenases in a Baculovirus/Insect Cell System. AB - The baculovirus/insect cell heterologous expression system provides an important tool for investigating the catalytic activity of individual drug-metabolizing enzymes toward a particular substrate. In this chapter we describe a baculovirus/insect cell system that we have used for the expression of human and mouse flavin-containing monooxygenases. Methods are described for the generation of recombinant baculoviral DNAs, via both site-specific transposition in Escherichia coli and site-specific recombination in vitro; adaptation of Spodoptera frugiperda (Sf) 9 cells to shaking culture and to serum-free medium; cryopreservation and transfection of Sf9 cells; amplification of baculovirus and determination of viral titer; analysis of baculoviral DNA; and expression and analysis of recombinant proteins. PMID- 27699679 TI - Catalytic Assays for Human Cytochrome P450 : An Introduction. AB - Cytochrome P450 (P450) is a superfamily of individual monooxygenase enzymes that metabolize structurally diverse xenochemicals, including many clinically useful drugs and foreign chemicals widespread in the environment. P450 substrates that can be used to selectively monitor individual P450 enzymes or P450 subfamilies have been identified through studies using P450 enzyme-selective inhibitory antibodies and chemical inhibitors in conjunction with experiments utilizing individual cDNA-expressed P450 enzymes. This chapter describes P450 form selective substrates that can be used to monitor the activities of human P450 enzymes CYP1A, CYP1B1, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A, CYP4A11, and CYP7A1. Cautions that need to be exercised when using these substrates to probe for individual P450 activities in human liver and other tissues are discussed. PMID- 27699680 TI - Lateral and medial prefrontal contributions to emotion generation by semantic elaboration during episodic encoding. AB - Memories for emotion-laden stimuli are remembered more accurately than those for neutral stimuli. Although this enhancement reflects stimulus-driven modulation of memory by emotions, functional neuroimaging evidence of the interacting mechanisms between emotions generated by intentional processes, such as semantic elaboration, and memory is scarce. The present fMRI study investigated how encoding-related activation is modulated by emotions generated during the process of semantic elaboration. During encoding with fMRI, healthy young adults viewed neutral (target) pictures either passively or with semantic elaboration. In semantic elaboration, participants imagined background stories related to the pictures. Encoding trials with semantic elaboration were subdivided into conditions in which participants imagined negative, positive, or neutral stories. One week later, memories for target pictures were tested. In behavioral results, memories for target pictures were significantly enhanced by semantic elaboration, compared to passive viewing, and the memory enhancement was more remarkable when negative or positive stories were imagined. fMRI results demonstrated that activations in the left inferior frontal gyrus and dorsal medial prefrontal cortex (dmPFC) were greater during the encoding of target pictures with semantic elaboration than those with passive viewing, and that these activations further increased during encoding with semantic elaboration of emotional stories than of neutral stories. Functional connectivity between the left inferior frontal gyrus and dmPFC/hippocampus during encoding significantly predicted retrieval accuracies of memories encoded with self-generated emotional stories. These findings suggest that networks including the left inferior frontal region, dmPFC, and hippocampus could contribute to the modulation of memories encoded with the emotion generation. PMID- 27699682 TI - Development of SmokeFree Baby: a smoking cessation smartphone app for pregnant smokers. AB - Pregnant smokers may benefit from digital smoking cessation interventions, but few have been designed for this population. The aim was to transparently report the development of a smartphone app designed to aid smoking cessation during pregnancy. The development of a smartphone app ('SmokeFree Baby') to help pregnant women stop smoking was guided by frameworks for developing complex interventions, including the Medical Research Council (MRC), Multiphase Optimization Strategy (MOST) and Behaviour Change Wheel (BCW). Two integrative behaviour change theories provided the theoretical base. Evidence from the scientific literature and behaviour change techniques (BCTs) from the BCT Taxonomy v1 informed the intervention content. The app was developed around five core modules, each with a distinct intervention target (identity change, stress management, health information, promoting use of face-to-face support and behavioural substitution) and available in a 'control' or 'full' version. SmokeFree Baby has been developed as part of a multiphase intervention optimization to identify the optimum combination of intervention components to include in smartphone apps to help pregnant smokers stop smoking. PMID- 27699681 TI - Electrophysiological correlates of emotional face processing after mild traumatic brain injury in preschool children. AB - Evidence suggests that social skills are affected by childhood mild traumatic brain injury (mTBI), but the neural and affective substrates of these difficulties are still underexplored. In particular, nothing is known about consequences on the perception of emotional facial expressions, despite its critical role in social interactions and the importance of the preschool period in the development of this ability. This study thus aimed to investigate the electrophysiological correlates of emotional facial expressions processing after early mTBI. To this end, 18 preschool children (mean age 53 +/- 8 months) who sustained mTBI and 15 matched healthy controls (mean age 55 +/- 11 months) were presented with pictures of faces expressing anger, happiness, or no emotion (neutral) while event-related potentials (ERP) were recorded. The main results revealed that P1 amplitude was higher for happy faces than for angry faces, and that N170 latency was shorter for emotional faces than for neutral faces in the control group only. These findings suggest that preschool children who sustain mTBI do not present the early emotional effects that are observed in healthy preschool children at visuospatial and visual expertise stages. This study provides new evidence regarding the consequences of childhood mTBI on socioemotional processing, by showing alterations of emotional facial expressions processing, an ability known to underlie social competence and appropriate social interactions. PMID- 27699683 TI - Physical activity for children in elementary schools: time for a rethink? AB - In spite of the well-known benefits of physical activity, the vast majority of children in North America do not meet current international guidelines for accumulating sufficient health-enhancing physical activity. Indeed, despite considerable attention to this population health crisis, the current prevalence of inactivity, along with its concomitant health consequences, shows little sign of abating. In this paper, we identify acknowledged barriers to wide scale physical activity adoption and maintenance at the population level among children and propose a viable tripartite framework (albeit one that would require political support) that we hope will provide the basis for debate and implementation. We emphasize that each of these considerations, in isolation, would be insufficient to substantively address the problem, but when combined would ensure that all elementary school children (without any medical contraindication) are sufficiently active, rather than the minority of this population. PMID- 27699685 TI - Development of the Emotion Dysregulation Inventory: A PROMIS(r)ing Method for Creating Sensitive and Unbiased Questionnaires for Autism Spectrum Disorder. AB - The lack of sensitive measures suitable for use across the range of functioning in autism spectrum disorder (ASD) is a barrier to treatment development and monitoring. The Emotion Dysregulation Inventory (EDI) is a caregiver-report questionnaire designed to capture emotional distress and problems with emotion regulation in both minimally verbal and verbal individuals. The first two phases of the EDI's development are described, including: (1) utilizing methods from the Patient-Reported Outcomes Measurement Information System (PROMIS(r)) project to develop the item pool and response options; and (2) assessment of the EDI in psychiatric inpatients with ASD. The results suggest that the EDI captures a wide range of emotion dysregulation, is sensitive to change, and is not biased by verbal or intellectual ability. PMID- 27699684 TI - Design and Cohort Characteristics of the Social Spectrum Study: A Multicenter Study of the Autism Spectrum Among Clinically Referred Children. AB - This paper provides an overview of the design and cohort characteristics of the Social Spectrum Study: a clinical cohort study that used a two-phase sampling design to identify children at risk for ASD. After screening 1281 children aged 2.5-10 years who had been consecutively referred to one of six mental health services in the Netherlands, children who screened positive for ASD (n = 428) and a random selection of screen negatives (n = 240) were invited to participate in diagnostic assessments and questionnaires regarding the child, family and society. A 1-year follow-up was also conducted. Results from this study may contribute to knowledge of the identification and characterization of children with ASD, family processes, and the impact of ASD on the family and society. PMID- 27699687 TI - Detection of allergen sources in the homes of sensitized children. AB - OBJECTIVE: To identify the presence of environmental factors linked to the onset of allergies and asthma in the homes of children participating in an early detection program that were identified with sensitivity to common allergens in the region of Sonora, Mexico. METHODS: A walkthrough assessment was carried out in the homes of sensitized children; the research tools were the questionnaire and environmental checklist proposed by the Lowell Healthy Homes Program of the University of Massachusetts-Lowell. RESULTS: The results showed the presence of environmental allergen sources, to which most of the children in the study are sensitized, as well as the environmental conditions and habits that determine the quality of the indoor air of the households, were both related to triggering allergies and asthma in this population. A statistically significant association was found between the visual observation of dust inside homes and the sensitivity of children to dust mites. CONCLUSIONS: Dust found inside the home was the most relevant environmental factor related to positive cases of IgE in children. Early detection of allergies in children in the study and the methodology used in this investigation provided a useful framework for the design of plans and intervention alternatives in these homes to prevent the development of allergies and asthma panorama. These plans should be designed with a multidisciplinary approach to impact social, environmental and economic benefits in the family, improving the living conditions of the study population and contributing to the sustainable development goals of the United Nations for 2030. PMID- 27699689 TI - The distinctive characteristics of the hourly distribution of live births on specific days in Japan. AB - OBJECTIVES: Anomalous variations in live births on February 29/March 1, April 1/April 2 and the days before the New Year holidays/New Year holidays have been reported in Japan. The distribution of live births was investigated on those days and whether or not such dates were selected due to obstetric intervention is discussed. METHODS: Using a method similar to the [Formula: see text]-R control chart, anomalous variations in the hourly number of live births were detected. The number of unusual births was estimated. RESULTS: The number of live births at 13:00-16:59 hours was significantly higher from December 24 to 28 and significantly lower from December 29-January 3, February 29, and April 1, especially on weekdays. In hospitals, the increases from 9:00-12:59 and 13:00 16:59 hours from December 24 to 27 were approximately 10 and 25 %, respectively, of the expected births for those times in the mid-1980s; thereafter, the rates were 30 and 35 %. After 2000, the child births at 13:00-16:59 hours on February 29 and April 1 decreased by approximately 35 % in hospitals and clinics. The numbers of live births at 0:00-0:59 hours were significantly higher on March 1 and April 2 until 2001. CONCLUSION: Anomalous variations at 0:00-0:59 hours may be associated with fictitious reporting on birth certificates. Anomalous variations from 13:00 to 16:59 hours on weekdays suggest that many individuals may avoid obstetric intervention on February 29 and April 1 and that the number of higher-risk deliveries may significantly increase in the daytime on the days before the New Year holidays due to obstetric intervention for institutional reasons. PMID- 27699688 TI - Evaluation of the Japanese Metabolic Syndrome Risk Score (JAMRISC): a newly developed questionnaire used as a screening tool for diagnosing metabolic syndrome and insulin resistance in Japan. AB - OBJECTIVES: To prevent the onset of lifestyle-related diseases associated with metabolic syndrome (MetS) in Japan, research into the development of a useful screening method is strongly desired. We developed a new screening questionnaire (JAMRISC) utilizing a logistic regression model and evaluated its ability to predict the development of MetS, type 2 diabetes and other lifestyle-related diseases in Japanese populace. METHODS: JAMRISC questionnaire was sent to 1,850 individuals in Rumoi, a small city in Hokkaido. We received a total of 1,054 valid responses. To maximize the target individuals accurately diagnosed with MetS, logistic regression analysis was used to generate a unique metabolic syndrome score calculation formula as taking into consideration the clinical relevance of each question item as individual coefficients. RESULTS: The results of our comparative research utilizing both JAMRISC and Finnish Diabetes Risk Score (FINDRISC) questionnaires revealed the usefulness of JAMRISC for its ability to detect risks for MetS, pre-MetS, diabetes, and pre-diabetes. Study of disease risk detection via JAMRISC questionnaire targeting the 4283 residents of Rumoi indicated a high detection rate for pre-MetS (98.8 %), MetS (94.2 %), pre diabetes (85.1 %) and type 2 diabetes (94.9 %). In addition, JAMRISC was useful not only as a MetS risk score test, but also as a screening tool for diagnosing insulin resistance. CONCLUSIONS: JAMRISC questionnaire is a useful instrument for the detection of early risk of not only MetS and type 2 diabetes but also insulin resistance. PMID- 27699690 TI - Prevalence, adverse health, and risk factors in association with sensory impairments: data from a prospective cohort study of older Japanese. AB - Sensory impairments, mainly of vision and hearing, are prevalent among the older adults, and are the leading causes of disability in people aged 60 years and above around the world. However, epidemiological data on sensory impairments (prevalence, association with adverse health outcomes, risk and preventive factors, etc.) in community-dwelling older people are sparse in Japan. Using data from the Kurabuchi Study, a community-based prospective cohort study of adults aged 65 years or older, the author and colleagues estimated the prevalence of sensory impairments in this population. Vision and hearing impairments were associated with adverse health outcomes, such as depressive symptoms, dependence in activities of daily living, and early death. In addition, antioxidants, sunlight exposure, hyperglycaemia, and nutritional status were identified as possible risk or preventive factors for vision and/or hearing impairments. Further research is needed into whether the maintenance or improvement of sensory functions contributes to the extension of disability-free life expectancy. PMID- 27699691 TI - Factors associated with illicit opioid use in methadone maintenance treatment clients in 5 Provinces, China. AB - OBJECTIVES: To investigate factors associated with illicit opioid use among methadone maintenance treatment (MMT) population. METHODS: Participants were recruited from Beijing (2 clinics), Shanghai (2 clinics), Guangdong (2 clinics), Chongqing (2 clinics) and Gansu (1 clinic) provinces. Information about heroin use and MMT was obtained from a self-reported questionnaire, illicit opioid use was obtained from monthly medical records. Binary logistic regression was used to investigate factors associated with illicit opioid use. RESULTS: Five hundred ninety-eight eligible MMT participants were used for data analysis. Variables such as age, gender, route of heroin use and daily MMT dosages were associated with illicit opioid use. Compared with MMT participants aged <40 years, participants aged 40-44 years (P = 0.027, OR = 0.57, 95 % CI 0.35-0.94), 45-49 years (P < 0.001, OR = 0.41, 95 % CI 0.24-0.67) and >=50 years (P = 0.008, OR = 0.52, 95 % CI 0.33-0.85) were more likely not to have illicit opioid use. Compared with male participants, females were more likely to have illicit opioid use (P = 0.044, OR = 1.53, 95 % CI 1.01-2.32). Compared with inhalation heroin abusers, abusers with route of inhalation + injection heroin use were more likely to have illicit opioid use (P = 0.009, OR = 2.00, 95 % CI 1.19-3.36). Compared with daily MMT dosages <60 mg participants, participants with daily MMT dosages >80 mg were more likely to have illicit opioid use (P = 0.003, OR = 2.37, 95 % CI 1.35-4.15). CONCLUSIONS: Age, gender, route of heroin use and daily MMT dosages were associated with illicit opioid use. A tailored intervention is needed for a promotion of MMT. PMID- 27699692 TI - Psychological distress between chronic hemodialysis patients with and without low back pain. AB - OBJECTIVE: The aim of this study was to compare psychological distress between patients on chronic hemodialysis with and without chronic low back pain (CLBP). SUBJECTS AND METHODS: A total of 72 patients on chronic hemodialysis, aged 72.9 +/- 10.8 years, were enrolled in this cross-sectional study. Psychological distress using the K6, questionnaire for CLBP, and physical activity using the tri-accelerometer were evaluated. RESULTS: Twenty-nine patients (40.3 %) were having CLBP. The K6 scores were 4.0 +/- 4.6 and physical activity (n = 55) was 1.0 +/- 1.0 METs h/day. K6 scores in patients on chronic hemodialysis with CLBP were significantly higher than those in patients on chronic hemodialysis without CLBP even after adjusting for sex, age, duration of hemodialysis and physical activity. CONCLUSION: These results suggest that higher psychological distress was a fundamental feature in patients on chronic hemodialysis with CLBP. PMID- 27699693 TI - Elemental and immunohistochemical analysis of the lungs and hilar lymph node in a patient with asbestos exposure, a pilot study. AB - OBJECTIVES: Studies have shown that inhaled mine dust, such as asbestos, can be translocated to various organs including the lymph nodes. Recently, we have established a protocol that enables us to identify inhaled elements using paraffin embedded lung specimens by in-air microparticle-induced X-ray emission (micro-PIXE). However, little research has examined the concentration of these inhaled fibers in various organs or the mechanisms of their translocation. In this study, we compared the concentration of inhaled fibers in the lung parenchyma to the concentration in the hilar lymph node as well as to determine the elemental spatial distribution of the inhaled fibers in a patient with occupational asbestos exposure. METHODS: Lung tissues and hilar lymph node in a patient with asbestos exposure were used in this study. Elemental analysis was performed by in-air micro-PIXE. Immunohistochemical analysis was performed using anti CD163, smooth muscle actin, vimentin and beta-catenin antibody. RESULTS: The analysis revealed that the amount of inhaled silicon was approximately 6 times higher in the lymph node than in the lungs. The spatial analysis showed that silicon, iron and aluminium were co-localized in the hilar lymph node. The immunohistochemical analysis showed localized agreement of the inhaled fibers with macrophages, smooth muscle actin, and vimentin in the hilar lymph node. CONCLUSIONS: This study showed that in-air micro-PIXE could be useful for analyzing the elemental distribution and quantification of inhaled fibers in the human body. Furthermore, immunohistochemistry in combination with in-air micro PIXE analyses may help to determine the mechanism of mine dust distribution in vivo. PMID- 27699694 TI - Cognitive function is maintained in noninstitutionalized elderly Japanese requiring care with high levels of health-related quality of life. AB - BACKGROUND: Health-related quality of life (HRQOL) has been reported to be associated with cognitive function; however, whether or not this relationship involves causality is uncertain. This study aimed to determine whether HRQOL levels are associated with subsequent changes in cognitive function in elderly people requiring care. METHODS: Participants were 74 community-dwelling elderly people utilizing the long-term care service (69 % women) who underwent physical and psychological examinations at baseline and follow-up. The outcome was 2-year changes in Mini-Mental State Examination (?MMSE) score. The potential predictor was HRQOL level assessed by the EuroQol 5 dimension (EQ-5D) score (utility value) at baseline; other variables were body mass index (BMI), Barthel index, grip strength, Geriatric Depression Scale, serum albumin, and serum hemoglobin. Associations between EQ-5D and ?MMSE scores were assessed using correlation analysis, regression analysis, and analysis of covariance (ANCOVA). RESULTS: Mean age, BMI, and Barthel index at baseline were 81.6 years [standard deviation (SD) 8.2], 21.1 kg/m2 (SD 4.0), and 79 (SD 20), respectively; the mean ?MMSE score was -2.2 (SD 5.1). EQ-5D was significantly correlated with ?MMSE (partial r = 0.375, P = 0.0012). The mean ?MMSE values of the 1st, 2nd, and 3rd EQ-5D quartiles were 4.2 (adjusted P = 0.0050), -2.6 (adjusted P = 0.0476), and -2.4 (adjusted P = 0.0298), respectively, which were lower than the -0.1 of the reference 4th quartile. CONCLUSIONS: HRQOL as assessed by EQ-5D is associated with longitudinal cognitive decline in frail elderly people, and cognitive function may be maintained in individuals with high HRQOL levels.

AB - OBJECTIVES: The aim of the present study was to examine the associations of current smoking with five other unhealthy lifestyle behaviors among urban civil servants in Japan according to sex and occupational category. METHODS: The study included 10,232 urban civil servants in Japan who presented for a health check-up in 2011. We analyzed data on anthropometric measurements and self-reported lifestyle factors. RESULTS: Current smokers had a higher BMI than never smokers in white-collar workers, but not in blue-collar workers of both sexes. There were strong associations of current smoking with irregular breakfasting regardless of sex and occupational category. In males, current smokers were less likely to take exercise than ex-smokers in both occupational categories. CONCLUSIONS: The associations of current smoking with other unhealthy behaviors were modified by sex and occupational category. These results are useful for understanding the health risks among smokers according to sex and occupational category. PMID- 27699696 TI - Neuromechanical Modulation of the Achilles Tendon During Bilateral Hopping in Patients with Unilateral Achilles Tendon Rupture, Over 1 Year After Surgical Repair. AB - BACKGROUND: Patients who have had an Achilles tendon (AT) rupture repaired are potentially at higher risk for re-rupture than those without previous rupture. Little attention has been given to the neuromechanical modulation of muscle tendon interaction and muscle activation profiles during human dynamic movements after AT rupture repair. OBJECTIVE: The purpose of this study was to examine muscle-tendon behavior and muscle activation during bilateral hopping. METHODS: We enrolled nine subjects who had undergone surgical repair of unilateral AT rupture within the past 1-2 years. Subjects performed bilateral hopping while we took ultrasound, kinematic, and electromyogram recordings and measurements. AT behaviors were also recorded. We then compared responses between values obtained from the ruptured AT leg (LEGATR) and non-ruptured AT leg (LEGNOR). RESULTS: During hopping, the AT stretching amplitudes were greater in the LEGATR than in the LEGNOR, although the peak AT force and stiffness were smaller in the LEGATR than in the LEGNOR. The AT negative mechanical work did not show any significant differences between both legs. However, positive works were significantly lower in the LEGATR than in the LEGNOR. Electromyogram patterns in both soleus and tibialis anterior muscles clearly differed after ground contact for the LEGATR and the LEGNOR. CONCLUSIONS: These results suggest that the repaired ruptured AT can be compliant and have insufficient Young's modulus, which can influence mechanical responses in muscle activities. The modulation of agonist-antagonist muscle activities corresponding to the different levels of stiffness between the LEGATR and the LEGNOR may not be fully functioning during the pre-activation phase.

AB - BACKGROUND: Whether transgender people should be able to compete in sport in accordance with their gender identity is a widely contested question within the literature and among sport organisations, fellow competitors and spectators. Owing to concerns surrounding transgender people (especially transgender female individuals) having an athletic advantage, several sport organisations place restrictions on transgender competitors (e.g. must have undergone gender confirming surgery). In addition, some transgender people who engage in sport, both competitively and for leisure, report discrimination and victimisation. OBJECTIVE: To the authors' knowledge, there has been no systematic review of the literature pertaining to sport participation or competitive sport policies in transgender people. Therefore, this review aimed to address this gap in the literature. METHOD: Eight research articles and 31 sport policies were reviewed. RESULTS: In relation to sport-related physical activity, this review found the lack of inclusive and comfortable environments to be the primary barrier to participation for transgender people. This review also found transgender people had a mostly negative experience in competitive sports because of the restrictions the sport's policy placed on them. The majority of transgender competitive sport policies that were reviewed were not evidence based. CONCLUSION: Currently, there is no direct or consistent research suggesting transgender female individuals (or male individuals) have an athletic advantage at any stage of their transition (e.g. cross-sex hormones, gender-confirming surgery) and, therefore, competitive sport policies that place restrictions on transgender people need to be considered and potentially revised. PMID- 27699697 TI - Wrist Injuries in Tennis Players: A Narrative Review. AB - The wrist/hand complex forms the crucial final link in the kinetic chain between the body and the racquet and therefore has a number of important roles in the production of all tennis strokes. However, the internal and external loads that are created at the wrist during these strokes have the potential to contribute to pain and injury. Therefore, the purposes of this narrative review are to (1) determine the extent of the problem of wrist pain/injury in tennis players, (2) identify bony and soft tissue structures of the wrist that are susceptible to damage as a result of tennis play and (3) explore factors that may influence the development of wrist pain/injury in tennis players. The epidemiological data revealed two important points. First, some evidence suggests wrist pain/injury accounts for a higher percentage of total injuries in more recent studies (2014 2015) than in early studies (1986-1995). Second, the relative frequency of wrist pain/injury compared with other well-recognized problem areas for tennis players such as the shoulder complex, elbow and lumbar spine is noticeably higher in more recent studies (2014-2015) than in early studies (1986-1995), particularly among females. Collectively, this would seem to indicate that the problem of wrist pain/injury has increased in the modern game. In fact, some wrist injuries appear to be related to the use of certain forehand grip types and the predominant use of the two-handed backhand. While the loads experienced at the wrist during tennis stroke production seem to be below threshold levels for a single event, the cumulative effects of these loads through repetition would appear to be an important consideration, especially when inadequate time is allowed to complete normal processes of repair and adaptation. This is supported by the evidence that most wrist injuries in tennis are associated with overuse and a chronic time course. The complex interaction between load, repetition, and training practices in tennis, particularly among young developing players who choose a path of early specialization, needs to be further explored. PMID- 27699699 TI - The Optimal Load for Maximal Power Production During Upper-Body Resistance Exercises: A Meta-Analysis. AB - BACKGROUND: External mechanical power is considered to be one of the most important characteristics with regard to sport performance. OBJECTIVE: The purpose of this meta-analysis was to examine the effect of load on kinetic variables such as mean and peak power during bench press and bench press throw, thus integrating the findings of various studies to provide the strength and conditioning professional with more reliable evidence upon which to base their program design. METHODS: A search of electronic databases (MEDLINE, PubMed, Google Scholar, and Web of Science) was conducted to identify all publications up to 31 October 2015. Hedges' g (95 % confidence interval) was estimated using a weighted random-effect model, due to the heterogeneity (I 2) of the studies. Egger's test was used to evaluate possible publication bias in the meta-analysis. A total of 11 studies with 434 subjects and 7680 effect sizes met the inclusion criterion and were included in the statistical analyses. Load in each study was labeled as one of three intensity zones: zone 1 represented an average intensity ranging from 0 to 30 % of one repetition maximum (1RM); zone 2 between 30 and 70 % of 1RM; and zone 3 >= 70 % of 1RM. RESULTS: These results showed different optimal loads for each exercise examined. Moderate loads (from >30 to <70 % of 1RM) appear to provide the optimal load for peak power and mean power in the bench press exercise. Lighter loads (<30 % of 1RM) appear to provide the highest mean and highest peak power production in the bench press throw exercise. However, a substantial heterogeneity was detected I 2 > 75 %. CONCLUSION: The current meta-analysis of published literature provides evidence for exercise specific optimal power loading for upper body exercises. PMID- 27699702 TI - Ethanol production from N-acetyl-D-glucosamine by Scheffersomyces stipitis strains. AB - N-acetyl-D-glucosamine (GlcNAc) is the building block of chitin, which is one of the most abundant renewable resources in nature after cellulose. Therefore, a microorganism that can utilize GlcNAc is necessary for chitin-based biorefinery. In this study, we report on the screening and characterization of yeast strains for bioethanol production from GlcNAc. We demonstrate that Scheffersomyces (Pichia) stipitis strains can use GlcNAc as the sole carbon source and produce ethanol. S. stipitis NBRC1687, 10007, and 10063 strains consumed most of the 50 g/L GlcNAc provided, and produced 14.5 +/- 0.6, 15.0 +/- 0.3, and 16.4 +/- 0.3 g/L of ethanol after anaerobic fermentation at 30 degrees C for 96 h. The ethanol yields of these strains were approximately 81, 75, and 82 % (mol ethanol/mol GlcNAc consumed), respectively. Moreover, S. stipitis NBRC10063 maintained high GlcNAc-utilizing capacity at 35 degrees C, and produced 12.6 +/- 0.7 g/L of ethanol after 96 h. This strain also achieved the highest ethanol titer (23.3 +/- 1.0 g/L) from 100 g/L GlcNAc. To our knowledge, this is the first report on ethanol production via fermentation of GlcNAc by naturally occurring yeast strains. PMID- 27699700 TI - Sitting Less and Moving More: Improved Glycaemic Control for Type 2 Diabetes Prevention and Management. AB - Epidemiological evidence indicates that excessive time spent in sedentary behaviours (too much sitting) is associated with an increased risk of type 2 diabetes (T2D). Here, we highlight findings of experimental studies corroborating and extending the epidemiological evidence and showing the potential benefits for T2D of reducing and breaking up sitting time across the whole day. We also discuss future research opportunities and consider emerging implications for T2D prevention and management. This new evidence is stimulating an expansion of diabetes-related physical activity guidelines-suggesting that in addition to moderate-vigorous physical activity, reducing and regularly interrupting prolonged sitting time is likely to have important and varied benefits across the spectrum of diabetes risk. PMID- 27699701 TI - Oligosaccharides: a boon from nature's desk. AB - This article reviews the varied sources of oligosaccharides available in nature as silent health promoting, integral ingredients of plants as well as animal products like honey and milk. The article focuses on exotic and unfamiliar oligosaccharides like Galactooligosaccharides, Lactulose derived Galactooligosaccharides, Xylooligosaccharides, Arabinooligosaccharides and algae derived Marine oligosaccharides along with the most acknowledged prebiotic fructooligosaccharides. The oligosaccharides are named as on the grounds of the monomeric units forming oligomers with functional properties. The chemical structures, natural sources, microbial enzyme mediated synthesis and physiological effects are discussed. An elaborate account of the different types of oligosaccharides with special reference to fructooligosaccharides are presented. Finally, the profound health benefits of oligosaccharides are rigourously discussed limelighting its positive physiological sequel. PMID- 27699703 TI - Disruption of Pseudomonas putida by high pressure homogenization: a comparison of the predictive capacity of three process models for the efficient release of arginine deiminase. AB - Disruption of Pseudomonas putida KT2440 by high-pressure homogenization in a French press is discussed for the release of arginine deiminase (ADI). The enzyme release response of the disruption process was modelled for the experimental factors of biomass concentration in the broth being disrupted, the homogenization pressure and the number of passes of the cell slurry through the homogenizer. For the same data, the response surface method (RSM), the artificial neural network (ANN) and the support vector machine (SVM) models were compared for their ability to predict the performance parameters of the cell disruption. The ANN model proved to be best for predicting the ADI release. The fractional disruption of the cells was best modelled by the RSM. The fraction of the cells disrupted depended mainly on the operating pressure of the homogenizer. The concentration of the biomass in the slurry was the most influential factor in determining the total protein release. Nearly 27 U/mL of ADI was released within a single pass from slurry with a biomass concentration of 260 g/L at an operating pressure of 510 bar. Using a biomass concentration of 100 g/L, the ADI release by French press was 2.7-fold greater than in a conventional high-speed bead mill. In the French press, the total protein release was 5.8-fold more than in the bead mill. The statistical analysis of the completely unseen data exhibited ANN and SVM modelling as proficient alternatives to RSM for the prediction and generalization of the cell disruption process in French press. PMID- 27699704 TI - Bio-degumming technology of jute bast by Pectobacterium sp. DCE-01. AB - Among industrial fiber crops, jute is ranked second to cotton in terms of yield and planting area worldwide. The traditional water retting and chemical semi degumming methods restrict the development of the jute industry. Jute fiber can be extracted from jute bast through mechanical rolling (preprocessing), culture of bacteria, soaking fermentation (liquor ratio = 10, inoculum size = 1 %, temperature = 35 degrees C, and time = 15 h), inactivation, washing, and drying. Pectobacterium sp. DCE-01 secretes key degumming enzymes: pectinase, mannase, and xylanase, which match well the main non-cellulosic components of jute bast. Compared with the traditional water retting degumming, the bio-degumming cycle is shortened from more than 10 days to 15 h. The proposed bio-degumming achieved higher efficiency and lower pollution than water retting and chemical semi degumming. PMID- 27699705 TI - Kinetics of nitrous oxide (N2O) formation and reduction by Paracoccus pantotrophus. AB - Nitrous oxide (N2O) is a powerful greenhouse gas emitted from wastewater treatment, as well as natural systems, as a result of biological nitrification and denitrification. While denitrifying bacteria can be a significant source of N2O, they can also reduce N2O to N2. More information on the kinetics of N2O formation and reduction by denitrifying bacteria is needed to predict and quantify their impact on N2O emissions. In this study, kinetic parameters were determined for Paracoccus pantotrophus, a common denitrifying bacterium. Parameters included the maximum specific reduction rates, [Formula: see text], growth rates, [Formula: see text], and yields, Y, for reduction of NO3- (nitrate) to nitrite (NO2-), NO2- to N2O, and N2O to N2, with acetate as the electron donor. The [Formula: see text] values were 2.9 gN gCOD-1 d-1 for NO3- to NO2-, 1.4 gN gCOD-1 d-1 for NO2- to N2O, and 5.3 gN gCOD-1 d-1 for N2O to N2. The [Formula: see text] values were 2.7, 0.93, and 1.5 d-1, respectively. When N2O and NO3- were added concurrently, the apparent (extant) kinetics, [Formula: see text], assuming reduction to N2, were 6.3 gCOD gCOD-1 d-1, compared to 5.4 gCOD gCOD-1 d-1 for NO3- as the sole added acceptor. The [Formula: see text] was 1.6 d 1, compared to 2.5 d-1 for NO3- alone. These results suggest that NO3- and N2O were reduced concurrently. Based on this research, denitrifying bacteria like P. pantotrophus may serve as a significant sink for N2O. With careful design and operation, treatment plants can use denitrifying bacteria to minimize N2O emissions. PMID- 27699706 TI - Effectiveness of a multidisciplinary risk assessment and management programme diabetes mellitus (RAMP-DM) on patient-reported outcomes. AB - Little is known about how the patient-reported outcomes is influenced by multidisciplinary-risk-assessment-and-management-programme for patients with diabetes mellitus (RAMP-DM). This paper aims to evaluate the effectiveness of RAMP-DM on patient-reported outcomes. This was a prospective longitudinal study on 1039 diabetes mellitus patients (714/325 RAMP-DM/non-RAMP-DM) managed in primary care setting. 536 and 402 RAMP-DM participants, and 237 and 187 non-RAMP DM participants were followed up at 12 and 24 months with completed survey, respectively. Patient-reported outcomes included health-related quality of life, change in global health condition and patient enablement measured by Short Form 12 Health Survey version-2 (SF-12v2), Global Rating Scale, Patient Enablement Instrument respectively. The effects of RAMP-DM on patient-reported outcomes were evaluated by mixed effect models. Subgroup analysis was performed by stratifying haemoglobin A1c (HbA1c) (optimal HbA1c < 7 % and suboptimal HbA1c >= 7 %). RAMP DM with suboptimal HbA1c was associated with greater improvement in SF-12v2 physical component summary score at 12-month (coefficient:3.80; P-value < 0.05) and 24-month (coefficient:3.82;P-value < 0.05), more likely to feel more enabled at 12-month (odds ratio: 2.57; P-value < 0.05), and have improved in GRS at 24 month (odds ratio:4.05; P-value < 0.05) compared to non-RAMP-DM participants. However, there was no significant difference in patient-reported outcomes between RAMP-DM and non-RAMP-DM participants with optimal HbA1c. Participation in RAMP-DM is effective in improving physical component of HRQOL, Global Rating Scale and patient enablement among diabetes mellitus patients with suboptimal HbA1c, but not in those with optimal HbA1c. Patients with sub-optimal diabetes mellitus control should be the priority target population for RAMP-DM. This observational study design may have potential bias in the characteristics between groups, and randomized clinical trial is needed to confirm the results.

PMID- 27699707 TI - Heterogeneity in glucose response curves during an oral glucose tolerance test and associated cardiometabolic risk. AB - We aimed to examine heterogeneity in glucose response curves during an oral glucose tolerance test with multiple measurements and to compare cardiometabolic risk profiles between identified glucose response curve groups. We analyzed data from 1,267 individuals without diabetes from five studies in Denmark, the Netherlands and the USA. Each study included between 5 and 11 measurements at different time points during a 2-h oral glucose tolerance test, resulting in 9,602 plasma glucose measurements. Latent class trajectories with a cubic specification for time were fitted to identify different patterns of plasma glucose change during the oral glucose tolerance test. Cardiometabolic risk factor profiles were compared between the identified groups. Using latent class trajectory analysis, five glucose response curves were identified. Despite similar fasting and 2-h values, glucose peaks and peak times varied greatly between groups, ranging from 7-12 mmol/L, and 35-70 min. The group with the lowest and earliest plasma glucose peak had the lowest estimated cardiovascular risk, while the group with the most delayed plasma glucose peak and the highest 2 h value had the highest estimated risk. One group, with normal fasting and 2-h values, exhibited an unusual profile, with the highest glucose peak and the highest proportion of smokers and men. The heterogeneity in glucose response curves and the distinct cardiometabolic risk profiles may reflect different underlying physiologies. Our results warrant more detailed studies to identify the source of the heterogeneity across the different phenotypes and whether these differences play a role in the development of type 2 diabetes and cardiovascular disease. PMID- 27699708 TI - Frequency of Cushing's syndrome due to ACTH-secreting adrenal medullary lesions: a retrospective study over 10 years from a single center. AB - Cushing's syndrome due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions has occasionally been described. We retrospectively reviewed all 164 cases of Cushing's syndrome and 77 cases of pheochromocytomas during 10 years. Of all cases with Cushing's syndrome, only two cases (1.2 %) were due to ectopic adrenocorticotropic hormone production from adrenal medullary lesions (one case of pheochromocytoma and one case of adrenal medullary hyperplasia). Of all pheochromocytomas only the above-mentioned case (1.3 %) also gave rise to an ectopic adrenocorticotropic hormone syndrome. The clinical presentation of adrenocorticotropic hormone-secreting pheochromocytoma and adrenal medullary hyperplasia can be anything from mild to dramatic. These are rare conditions important to bear in mind in the workup of a patient with Cushing's syndrome or with pheochromocytoma. The identification of ectopic adrenocorticotropic hormone secretion from adrenal medullary lesions can be life saving.

AB - Respect for personal autonomy in decision-making is one of the four ethical principles in medical circumstances. This paper aims to present evidence that can be considered good exemplars in the clarification of the ethical viewpoints of the western and Shi'i Islamic perspectives on this issue. The method followed was originally a search in international indexing services in April 2016. Our findings point towards various controversies on individuals' autonomy lead to different decision making outcomes by health workers in both different traditions. We concluded that although Shi'i Islamic jurisprudence does not seem to allow for personal autonomy in the sense it is understood in a western context, evidence indicates that Shi'i Islamic jurisprudence respects personal autonomy. PMID- 27699714 TI - Investigating the Effect of Line Dipole Magnetic Field on Hydrothermal Characteristics of a Temperature-Sensitive Magnetic Nanofluid Using Two-Phase Simulation. AB - Hydrothermal characteristics of a temperature-sensitive magnetic nanofluid between two parallel plates are investigated in the presence of magnetic field produced by one or multiple line dipole(s) using the two-phase mixture model. As the nanofluid reaches the region where the magnetic field is applied, a rotation is developed due to the dependency of magnetization on temperature. This can lead to mixing in the flow and more uniform distribution of temperature due to the disturbance caused in the boundary layer, and consequently, enhancement in convective heat transfer. The results indicate that the disturbance in boundary layer adjacent to the lower wall is more significant than the upper wall. By application of the magnetic field, the convective heat transfer increases locally for both walls. Due to the intensified mixing, a sudden pressure drop occurs when the fluid reaches the region where the magnetic field is applied. For greater magnetic field strengths and lower Reynolds numbers, the improvement in convective heat transfer is more significant. For small magnetic field strengths, the effect of applying magnetic field on the upper wall is much smaller than that on the lower wall; however, this effect becomes almost the same for both walls at great magnetic field strengths. PMID- 27699715 TI - L-Cysteine-Assisted Synthesis of Urchin-Like gamma-MnS and Its Lithium Storage Properties. AB - MnS has been attracting more and more attentions in the fields of lithium ion batteries (LIBs) because of its high energy density and low voltage potential. In this paper, we present a simple method for the preparation of urchin-like gamma MnS microstructures using L-cysteine and MnCl2 . 4H2O as the starting materials. The urchin-like gamma-MnS microstructures exhibit excellent cycling stability (823.4 mA h g-1 at a current density of 500 mA g-1, after 1000 cycles). And the discharge voltage is about 0.75 V, making it a good candidate for the application as the anode material in LIBs. SEM, TEM, and XRD were employed to inspect the changes of the active materials during the electrochemical process, which clearly indicate that the structural pulverization and reformation of the gamma-MnS microstructures play important roles for the maintenance of the electrochemical performance during the charge/discharge process. PMID- 27699716 TI - Comparison of Silicon Nanocrystals Prepared by Two Fundamentally Different Methods. AB - This work compares structural and optical properties of silicon nanocrystals prepared by two fundamentally different methods, namely, electrochemical etching of Si wafers and low-pressure plasma synthesis, completed with a mechano-photo chemical treatment. This treatment leads to surface passivation of the nanoparticles by methyl groups. Plasma synthesis unlike electrochemical etching allows selecting of the particle sizes. Measured sizes of the nanoparticles by dynamic light scattering show 3 and 20 nm for electrochemically etched and plasma synthetized samples, respectively. Plasma-synthetized 20-nm particles do not exhibit photoluminescence due to absence of quantum confinement effect, and freshly appeared photoluminescence after surface passivation could indicate presence of organic molecules on the nanoparticle surface, luminescing instead of nanocrystal core. Electrochemically etched sample exhibits dramatic changes in photoluminescence during the mechano-photo-chemical treatment while no photoluminescence is observed for the plasma-synthetized one. We also used the Fourier transform infrared spectroscopy for comparison of the chemical changes happened during the treatment. PMID- 27699717 TI - MPTP Induces Systemic Parkinsonism in Middle-Aged Cynomolgus Monkeys: Clinical Evolution and Outcomes. AB - In this study, we developed a systemic PD model in middle-aged cynomolgus monkeys using individualized low-dose MPTP, to explore effective indicators for the early prediction of clinical outcomes. MPTP was not stopped until the animals showed typical PD motor symptoms on days 10 to 13 after MPTP administration when the Kurlan score reached 10; this abrogated the differences in individual susceptibility to MPTP. The clinical symptoms persisted, peaking on days 3 to 12 after MPTP withdrawal (rapid progress stage), and then the Kurlan score plateaued. A Kurlan score at the end of the rapid progress stage >15 reflected stable or slowly-progressive PD, while a score <15 indicated spontaneous recovery. The entire clinical evolution and outcome of the systemic PD model was characterized in this study, thus providing options for therapeutic and translational research. PMID- 27699718 TI - Olfactory Dysfunction in Parkinson's Disease Patients with the LRRK2 G2385R Variant. AB - Olfactory dysfunction has been reported in Parkinson's disease (PD) patients carrying the LRRK2 G2019S variant in Caucasians but rarely in those with the LRRK2 G2385R variant. In this study, we performed genotyping for the LRRK2 G2385R variant in PD patients recruited from the Movement Disorder Clinic of Xuanwu Hospital in Beijing and in healthy controls randomly selected from the Beijing Longitudinal Study on Aging cohort. The "five-odor olfactory detection array", an olfactory threshold test, was used to assess olfactory function. One hundred and eighty-six participants were enrolled, comprising 43 PD patients without (iPD) and 25 with (LRRK2-PD) the LRRK2 G2385R variant, and 118 healthy controls. Our results showed that the threshold of olfactory identification was significantly worse in PD patients than in controls, but not significantly different between the iPD and LRRK2-PD groups. These findings suggested that although olfactory function in LRRK2-PD patients is impaired, it is similar to that in iPD patients.

PMID- 27699720 TI - Preclinical in vivo and in vitro comparison of the translocator protein PET ligands [18F]PBR102 and [18F]PBR111. AB - PURPOSE: To determine the metabolic profiles of the translocator protein ligands PBR102 and PBR111 in rat and human microsomes and compare their in vivo binding and metabolite uptake in the brain of non-human primates (Papio hamadryas) using PET-CT. METHODS: In vitro metabolic profiles of PBR102 and PBR111 in rat and human liver microsomes were assessed by liquid chromatography-tandem mass spectrometry. [18F]PBR102 and [18F]PBR111 were prepared by nucleophilic substitution of their corresponding p-toluenesulfonyl precursors with [18F]fluoride. List mode PET-CT brain imaging with arterial blood sampling was performed in non-human primates. Blood plasma measurements and metabolite analysis, using solid-phase extraction, provided the metabolite profile and metabolite-corrected input functions for kinetic model fitting. Blocking and displacement PET-CT scans, using PK11195, were performed. RESULTS: Microsomal analyses identified the O-de-alkylated, hydroxylated and N-de-ethyl derivatives of PBR102 and PBR111 as the main metabolites. The O-de-alkylated compounds were the major metabolites in both species; human liver microsomes were less active than those from rat. Metabolic profiles in vivo in non-human primates and previously published rat experiments were consistent with the microsomal results. PET-CT studies showed that K1 was similar for baseline and blocking studies for both radiotracers; VT was reduced during the blocking study, suggesting low non specific binding and lack of appreciable metabolite uptake in the brain. CONCLUSIONS: [18F]PBR102 and [18F]PBR111 have distinct metabolic profiles in rat and non-human primates. Radiometabolites contributed to non-specific binding and confounded in vivo brain analysis of [18F]PBR102 in rodents; the impact in primates was less pronounced. Both [18F]PBR102 and [18F]PBR111 are suitable for PET imaging of TSPO in vivo. In vitro metabolite studies can be used to predict in vivo radioligand metabolism and can assist in the design and development of better radioligands.

PMID- 27699721 TI - Efficacy of long-term tenofovir-based rescue therapy in patients with chronic hepatitis B refractory to nucleoside/nucleotide analogs. AB - BACKGROUND: Few studies have investigated the efficacy of long-term tenofovir disoproxil fumarate (TDF)-based rescue therapy in patients with chronic hepatitis B refractory to nucleoside/nucleotide analogs. METHODS: We retrospectively analyzed 40 Japanese patients with chronic hepatitis B refractory to nucleoside/nucleotide analogs who received TDF-based rescue therapy [TDF monotherapy, TDF plus lamivudine (LAM) combination therapy, or TDF plus entecavir (ETV) combination therapy] followed up for a median of 45 months (range 14-99 months). Viral response, changes in hepatitis B surface antigen levels from the baseline, and viral breakthrough during therapy were analyzed. RESULTS: The proportion of patients with undetectable serum hepatitis B virus (HBV) DNA levels (less than 2.1 log copies per milliliter) (viral response) during TDF-based rescue therapy was 68, 78, 85, 88, 83, 81, 88, and 100 % at 0.5, 1, 1.5, 2, 2.5, 3, 3.5, and 4 years respectively. There were no differences in the viral response rate between the TDF plus LAM group and the TDF plus ETV group. The mean reduction from the baseline in hepatitis B surface antigen levels in patients with LAM-resistant HBV was greater than the reductions in patients with adefovir dipivoxil (ADV)-resistant or ETV-resistant HBV at 2 and 3 years (P = 0.024, and P = 0.025 respectively). However, two patients with ADV- or ETV-resistant HBV at the baseline developed viral breakthrough during TDF-based rescue therapy. CONCLUSIONS: Long-term therapy with a TDF-based rescue regimen demonstrated high viral suppression in patients in whom LAM plus ADV combination therapy, ETV plus ADV combination therapy, or ETV monotherapy had failed. However, patients with ADV- or ETV-resistant HBV at the baseline may develop viral breakthrough and resistance, and careful follow-up is advised. PMID- 27699725 TI - Arthroscopic Lateral Retinacular Release and Modified Elmslie-Trillat Operation Improve Severe Isolated Lateral Patello-Femoral Osteoarthritis. AB - To evaluate whether arthroscopic lateral retinacular release and the modified Elmslie-Trillat operation improve osteoarthritis (OA) progression and clinical outcomes in patients with severe isolated lateral patello-femoral OA. Nine women (11 knees) and one man (one knee) with isolated late-stage lateral patello femoral OA underwent surgery. The severity of patello-femoral OA was recorded using the Merchant method, while the level of pain and anterior knee function were scored using the visual analogue scale (VAS) and Kujala knee scores, respectively. The articular cartilage was graded under arthroscopy using the Outerbridge classification. All of the patients underwent the modified Elmslie Trillat operation after arthroscopic surgery, including lateral retinacular release. Ten patients (12 knees) had a mean 6.45 +/- 0.80 mm of medial transfer, 6.02 +/- 0.80 mm of anterior transfer of the tibial tubercle, and follow-up of 67.0 months. The mean VAS and Kujala knee scores improved from 8 +/- 0.17 preoperatively to 2.33 +/- 0.33 on the last follow-up and from 43.08 +/- 2.09 to 68.83 +/- 2.59, respectively (both p < 0.001). Postoperatively, all had improved subchondral bone remodeling, including cyst resolution, density and trabeculae normalization, and subchondral smoothing in the patello-femoral compartment. The patello-femoral joint space and patellar thickness increased from 0.39 +/- 0.16 mm to 1.77 +/- 0.18 mm and from 18.28 +/- 0.67 mm to 19.60 +/- 0.69 mm, respectively (p < 0.001 and p = 0.005). Treatment of severe isolated lateral patello-femoral OA using arthroscopic lateral retinacular release and the modified Elmslie-Trillat operation can improve pain relief, functional outcomes, and subchondral bone remodeling, and also restore the patello-femoral joint space and patellar thickness. Prompt transfer of the tibial tubercle seems to reverse the progress of OA radiographically. PMID- 27699724 TI - Comparing epsilon-Aminocaproic Acid and Tranexamic Acid in Reducing Postoperative Transfusions in Total Knee Arthroplasty. AB - Multiple studies have shown tranexamic acid (TXA) to reduce blood loss and transfusion rates in patients undergoing total knee arthroplasty (TKA). Accordingly, TXA has become a routine blood conservation agent for TKA. In contrast, epsilon-aminocaproic acid (EACA), a similar acting antifibrinolytic to TXA, has been less frequently used. This study evaluated whether EACA is as efficacious as TXA in reducing postoperative blood transfusion rates and compared the cost per surgery between agents. A multicenter retrospective chart review of elective unilateral TKA from April 2012 through December 2014 was performed. Five hospitals within a health care system participated. Data collected included age, gender, severity of illness score, use of antifibrinolytic and dose, red blood cell (RBC) transfusions and the number of units, and preadmission and discharge hemoglobin (Hb). Dosing of the antifibrinolytic differed based on the agent used, 5 or 10 g (based on weight) for EACA versus 1 g for TXA. The institutional acquisition cost of each antifibrinolytic was obtained and averaged over the study period. Of 2,922 primary unilateral TKA cases, 820 patients received EACA, 610 patients received TXA, and 1,492 patients received no antifibrinolytic (control group). Compared with the control group both EACA and TXA groups had significantly fewer patients transfused (EACA 2.8% [p < 0.0001], TXA 3.2% [p < 0.0001] vs. control 10.8%) and lower mean RBC units transfused per patient (EACA 0.05 units/patient [pt] [p < 0.0001], TXA 0.05 units/pt [p < 0.0001] vs. control 0.19 units/pt]. There was no difference in mean RBC units transfused per patient, percentage of patients transfused, and discharge Hb levels between the EACA and TXA groups (p = 0.822, 0.236, and 0.322, respectively). Medication acquisition cost for EACA averaged $2.23 per surgery compared with TXA at $39.58 per surgery. Administration of EACA or TXA significantly decreased postoperative transfusion rates compared with no antifibrinolytic therapy. Utilization of EACA for unilateral TKA proved to be comparable to TXA in all studied aspects at a lower cost. The level of evidence for the study is Level 3. PMID- 27699722 TI - Imaging as an Outcome Measure in Multiple Sclerosis. AB - Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system. Magnetic resonance imaging (MRI) is sensitive to lesion formation both in the brain and spinal cord. Imaging plays a prominent role in the diagnosis and monitoring of MS. Over a dozen anti-inflammatory therapies are approved for MS and the development of many of these medications was made possible through the use of contrast-enhancing lesions on MRI as a phase II outcome. A similar phase II outcome method for the neurodegeneration that underlies progressive courses of the disease is still unavailable. Although magnetic resonance is an invaluable tool for the diagnosis and monitoring of treatment effects in MS, several imaging barriers still exist. In general, MRI is less sensitive to gray matter lesions, lacks pathological specificity, and does not provide quantitative data easily. Several advanced imaging methods including diffusion tensor imaging, magnetization transfer, functional MRI, myelin water fraction imaging, ultra-high field MRI, positron emission tomography, and optical coherence tomography of the retina study promising ways of overcoming the difficulties in MS imaging. PMID- 27699726 TI - Modified Elmslie-Trillat Procedure for Recurrent Dislocation of the Patella. AB - Many groups have reported good to excellent clinical outcomes of the Elmslie Trillat (ET) procedure for recurrent dislocation of the patella. However, the mean follow-up period of these studies was no more than 5 years. We hypothesized that the long-term postoperative outcomes of the modified ET procedure for recurrent dislocation of the patella would be acceptable compared with those of other procedures. The long-term postoperative outcomes of patients treated with the modified ET procedure were examined. A total of 31 knees in 27 patients with recurrent dislocation of the patella who underwent a modified ET procedure (without medial capsular plication) were evaluated. The mean follow-up period was 13.0 years. Pre- and postoperative radiographs were examined to determine the Q angle, tilting angle, lateral shift ratio, sulcus angle, congruence angle, and Insall-Salvati index. Clinical outcomes were evaluated based on the Fulkerson patellofemoral joint evaluation score, Kujala score, and the presence of the apprehension sign. Radiological evaluation revealed significant postoperative improvements in the Q-angle, tilting angle, lateral shift ratio, congruence angle, Kujala score, and Fulkerson score (p < 0.001). Sixty-eight percent of all patients had a "good" or "excellent" Fulkerson score. The apprehension sign continued to be shown for six knees. Progression of osteoarthritic changes was observed in three knees, and one knee was symptomatic. The modified ET procedure provided satisfactory outcomes based on radiological and clinical evaluations. These results show the long-term effectiveness and safety of the modified ET procedure for recurrent patellar dislocation. PMID- 27699728 TI - Multicenter, Multisurgeon Research Groups Updates. PMID- 27699727 TI - A Comparison of Large Soft Palate Defect Reconstruction Using the New "Tunnel Structure" and Traditional "Port Structure" Methods. AB - Background For soft palate defects of more than two-thirds, we previously described the bent anterolateral thigh (ALT) method in which the pharyngeal isthmus was reconstructed as a tunnel structure. In this study, we compared the new "tunnel structure" reconstruction in our bent ALT flap method and the traditional "port structure" reconstruction. Methods From April 2010 to March 2015, 25 patients in Saitama Cancer Center (Saitama, Japan) underwent oropharyngeal tumor resection including soft palate resection. In patients who had soft palate resection of less than two-thirds, the Gehanno method was performed in 10 patients (the data were shown as a comparison). In patients who had soft palate resection of more than two-thirds, the pharyngeal isthmus was reconstructed as a tunnel structure using the bent ALT flap method in eight patients and as a port structure in seven patients. The functional outcomes were assessed by interviewing patients about their symptoms and measuring the standard articulation test. Results Postoperative function was favorably maintained at equal levels in the tunnel structure reconstruction group and the Gehanno method group at approximately 12 months postoperation. However, in most patients in the port structure reconstruction group, the pharyngeal isthmus became larger after 12 months postoperation and the articulation test was significantly worse than the Gehanno group and the tunnel group. Conclusion The bent ALT flap method had superior results to the conventional method. Thus the pharyngeal isthmus should be reconstructed as a tunnel structure for patients with soft palate defects of more than two-thirds. PMID- 27699730 TI - Management of Coagulopathy in Postpartum Hemorrhage. AB - The purpose of this article is to review the use of blood products and hemostatic agents in the management of coagulopathy at the time of postpartum hemorrhage. Blood product administration strategies are broadly reviewed, including the role of the blood bank, the role of massive transfusion protocols, the role of laboratory monitoring, and the role of anesthesia management. Aspects of patient blood management are discussed. The concept refers to an evidence-based, comprehensive, multidisciplinary approach to optimizing the care of patients who might need transfusion and includes measures to avoid or minimize transfusion such as preoperative anemia management, cell salvage, and the use of hemostatic medication to reduce bleeding. The contributions of individual blood components red blood cells, plasma, cryoprecipitate, and platelets-are described. Current data regarding the complementary role of hemostatic agents-antifibrinolytic agents and clotting factor concentrates-are presented. Two developments in blood component pathogen reduction are introduced. PMID- 27699729 TI - The Management of Factor XI Deficiency in Pregnancy. AB - Management of factor XI (FXI) deficiency in pregnancy is complicated by lack of correlation between FXI level and bleeding risk. Clinicians should be vigilant about the potential for prolonged or excessive bleeding following miscarriage or termination of pregnancy, or postpartum hemorrhage (PPH). A multidisciplinary approach along with an individual care plan is recommended to prevent bleeding complications. Assessment of bleeding history, FXI level, and global tests of hemostasis can aid management decisions regarding hemostatic prophylaxis. The risk of PPH can be minimized by obstetric measures to avoid uterine atony and genital trauma, in addition to provision of appropriate hemostatic prophylaxis for labor and delivery. Women with FXI deficiency can be given the option of regional anesthesia, provided that prior consideration has been given to assessment of potential bleeding risk and appropriate treatment strategies are implemented. Antifibrinolytic agents are effective for the majority of women with FXI deficiency, but those with severe deficiency/phenotype require FXI concentrate. Recombinant activated factor VII (rFVIIa) has also been used successfully to prevent bleeding in FXI deficiency. However, all treatments should be used with caution in pregnancy due to thrombogenic potential. Neonatal bleeding complications are rare in FXI deficiency; however, hemostatic assessment and cover are important for invasive procedures such as circumcision. PMID- 27699731 TI - The Effect of Intramural Botulinum Toxin Injections on the Elongation of the Piglet Oesophagus Is Time Dependent. AB - Introduction One in 4,000 infants is born with oesophageal atresia. Approximately 15% of these have a long gap oesophageal atresia, where primary anastomosis is difficult or impossible. Previous studies have shown an effect of intramural botulinum toxin type A (BTX-A) injections on the elongation and max load of the esophagus 1 hour after injection. We hypothesized that a longer waiting period of 2 hours could increase this effect. Methods Forty-five piglets were randomized into three groups. Two treatment groups received 2 units/kg of BTX-A and one group received saline. After 1 or 2 hours, a segment of the esophagus was harvested and put in a stretch-tension device to assess elongation and max load. Results Elongation from preload to max load and percentage elongation in the BTX A 2h group (17.09 mm, 46.46%) was significantly higher compared with the BTX-A 1h group (13.59 mm, 40.16%) and the placebo group (13.77 mm, 39.92%). Conclusion Elongation of the piglet esophagus was significantly improved with a 2-hour waiting period after BTX-A injection. Injections with BTX-A could be useful in oesophageal atresia, where primary anastomosis is not possible. PMID- 27699732 TI - A New Era in Diagnostic Ultrasound, Superb Microvascular Imaging: Preliminary Results in Pediatric Hepato-Gastrointestinal Disorders. AB - Introduction Superb microvascular imaging is a new ultrasound image processing technique that uses advanced clutter suppression to extract flow signals from vessels and which helps us visualize very small vascular structures that were not previously visible without the use of a contrast agent. We herein analyzed the usefulness of superb microvascular imaging in the diagnosis of hepato gastrointestinal disorders in pediatric patients. Materials and Methods Fifty-six pediatric patients who underwent a total of 81 superb microvascular imaging examinations with an Aplio 300 ultrasound system (Toshiba Medical Systems, Tokyo, Japan) were enrolled in this study. The subjects underwent conventional ultrasound examinations, including Doppler imaging followed by superb microvascular imaging. The superb microvascular imaging findings and standard imaging were compared. All of the examinations were performed without sedation. Results The average age of the patients (male, n = 38; female, n = 18) was 4 years. The clinical diagnoses included hepatobiliary disorders (n = 29), acute appendicitis (n = 10), and other intestinal disorders (n = 17). The target organs for superb microvascular imaging were the liver, appendix, rectum, intestine, gallbladder, and lymph node. In most of the patients, superb microvascular imaging achieved the excellent visualization of microvascular structures, revealing abnormal vasculature in 21 out of 46 (45.7%) examinations of the liver, 9/9 (100%) examinations of the appendix, 0/11 (0%) examinations of the rectum, 9/11 (81.8%) examinations of the intestine, 0/1 (0%) examinations of the gallbladder, and 3/3 (100%) examinations of the lymph nodes. Superb microvascular imaging was superior to Doppler imaging for depicting the microvascular structures. Conclusions Superb microvascular imaging is especially useful for depicting the microvascular flow and can aid in the diagnosis and treatment planning for pediatric patients with hepato-gastrointestinal disorders. PMID- 27699733 TI - Surgical Treatment of Childhood Inflammatory Myofibroblastic Tumors. AB - Aim A retrospective study was performed to evaluate the clinical features, diagnostic methods, and treatment alternatives of childhood inflammatory myofibroblastic tumors (IMTs). Patients and Methods Patients who underwent surgical treatment for IMT between 2000 and 2015 were evaluated for age, sex, presenting symptoms, physical examination findings, diagnostic methods, treatment modalities, histopathologic findings, and results of surgical treatment during long-term follow-up. Results Eleven patients who underwent surgical treatment were included in the study. Male:female ratio was 7:4 and the mean age of the patients was 6.09 years (1-10 years). Presenting symptoms were respiratory difficulty, cough (n = 7, 63.3%), abdominal pain, vomiting (n = 2, 18.8%), loss of body weight (n = 1, 9.09%), palpable mass (n = 1, 9.09%), and rectal bleeding (n = 1, 9.09%). Ultrasonography (n = 4, 36.3%) and computed tomography (n = 9, 81.1%) were used for diagnosis. Localizations of tumors were lungs (n = 5, 45.4%), mediastinum (n = 2, 18.1%), spleen (n = 1, 9.09%), neck (n = 1, 9.09%), colon (n = 1, 9.09%), and rectum (n = 1, 9.09%). The mean size of mass was 6.6 cm (2-12 cm) and six patients were diagnosed with preoperative biopsy. Lung lobectomy (right lower lobe; n = 3, right middle and lower lobe; n = 2), total resection of mass with adjacent bowel (n = 2), partial splenectomy (n = 1), total resection of neck mass (n = 1), and incomplete resection (n = 2) were the choice of surgical treatment. Incomplete resection was performed in masses closely adjacent to atrium and mediastinal structures. In histopathologic evaluation, surgical margins were free of tumor in four cases, positive in six cases, and were not reported in one case. Anaplastic lymphoma kinase (ALK) positivity was detected in six cases, negative in two cases, and was not evaluated in three cases. Two cases who had residual mass with positive ALK received chemotherapy. Mean follow-up time was 68.2 months (5 months to 12 years). During follow-up, there was no recurrence or distant metastasis. Ten patients survived and one patient was lost to follow-up. Conclusion IMT is a rare tumor of childhood with a spectrum of clinical findings because of variable localization. Surgical treatment is the first choice of treatment. Patients with residual mass and ALK positivity may require medical treatment. In our series, long-term survival of patients was favorable in patients with total resection. PMID- 27699734 TI - [Overview of Endometrial Cancer]. AB - Endometrial cancer is the most common gynecological cancer and the sixth most common cancer among women in Taiwan. Risk factors for endometrial cancer include obesity, long-term estrogen replacement therapy, diabetes mellitus, hypertension, nulliparty, early age at menarche, late age at menopause, and tamoxifen therapy. Most women with endometrial cancer exhibit abnormal uterine bleeding. Endometrial cancer is often diagnosed at stage I. Surgery alone is the primary treatment for stage I endometrial cancer. Fortunately, mortality rates for endometrial cancer are relatively low, with a 5-year survival rate of 81% among women who are diagnosed with endometrial cancer in Taiwan. However, the common side effects of treatment, including infertility, surgical menopause, lymphedema of the lower extremities, sexual dysfunction, distress, and fatigue, impact significantly on the quality of life of patients. Lifestyle changes such as keeping physically active and eating a diet that is high in fruit and vegetables may alleviate symptoms and improve quality of life in women who have undergone treatment for endometrial cancer. PMID- 27699735 TI - [Treatment Decision-Making Process of Cancer Patients]. AB - The decision-making process that is used by cancer patients to determine their treatment has become more multi-foci, difficult and complicated in recent years. This has in part been attributed to the increasing incidence rate of cancer in Taiwan and the rapid development of medical technologies and treatment modalities. Oncology nurses must assist patients and family to make informed and value-based treatment decisions. Decision-making is an information process that involves appraising one's own expectation and values based on his/her knowledge on cancer and treatment options. Because cancer treatment involves risks and uncertainties, and impacts quality of life, the treatment decision-making for cancer is often stressful, or even conflicting. This paper discusses the decision making behaviors of cancer patients and the decisional conflict, participation, and informational needs that are involved in cancer treatment. The trend toward shared decision-making and decisional support will be also explored in order to facilitate the future development of appropriate clinical interventions and research. PMID- 27699736 TI - [Chemotherapy-Induced Amenorrhea and Menopause Symptoms in Women With Breast Cancer]. AB - Chemotherapy is a common adjuvant therapy for breast cancer that improves survival rates by killing residual cancer cells. However, this intervention may damage the germ cells within the ovary and interrupt the menstrual cycle, ultimately leading to chemotherapy-induced amenorrhea (CIA). The incidence of CIA depends on how broadly this term is defined. Around 75% of premenopausal breast cancer women treated with chemotherapy will develop CIA. Age, having a relatively long chemotherapy cycle duration, being estrogen-receptor positive, and using Tamoxifen all increase the risk of CIA. Although CIA may be associated with better prognosis outcomes, breast cancer women must subsequently deal with the various menopausal symptoms that are associated with a CIA-induced drop in estrogen level (such as cognitive function decline, physical and psychological symptoms, vasomotor symptoms, reproductive and sexual function problems, and body weight change). The present article describes the female menstrual cycle, the mechanism and risk factors of CIA, and the range of menopausal symptoms. Furthermore, we summarized methods of assessing menopausal symptoms and compared five common rating scales of menopausal symptoms. By better understanding the potential menopausal symptoms, researchers and clinicians may then select the most appropriate scale based on the situational needs in order to evaluate the severity of menopausal symptoms that are experienced by breast cancer women. PMID- 27699737 TI - [Cancer-Related Posttraumatic Stress Symptoms in Patients With Cancer]. AB - At least half of patients with cancer experience emotional distress (e.g., posttraumatic stress symptoms). Most of the studies on the emotional distress of Taiwanese cancer patients have focused on issues of depression rather than on posttraumatic stress disorder. The scope of the present article covers the definitions of cancer-related posttraumatic stress disorder (CR-PTSD) and cancer related posttraumatic stress symptoms (CR-PTSS), identifies the differences and similarities between professional interview and self-administered measurement tools and their applications; analyzes the prevalence of CR-PTSD and CR-PTSS; identifies the possible contributing sociodemographic (younger age, female, low education, low socio-economic status), clinical (advanced stage, undergoing chemotherapy, just completed the therapy), and psychosocial (negative psychological traits, poor social support, and insufficient coping strategies) of CR-PTSD and CR-PTSS; and aggregates the effects of cognitive and psychosocial interventions on CR-PTSD and CR-PTSS. Furthermore, recommendations for clinical practice and research are discussed. This article is expected to provide practicing nurses with a basic concept of caring for emotional distress and to inspire researchers to conduct further study of issues related to CR-PTSD and CR PTSS. PMID- 27699738 TI - [The Mediating Role of Parenting Self-Efficacy on Parenting Stress and Quality of Life in Parents of Young Children With Developmental Delay]. AB - BACKGROUND: Previous studies indicate that parents of developmentally delayed children have higher parenting stress (PS) and lower quality of life (QoL) than parents of healthy children. Parenting self-efficacy (PSE) may mediate the effects of PS on the QoL of parents. PURPOSE: The present study explores the mediating role of PSE between PS and the QoL of parents of developmentally delayed children and compares the differences in several variables between fathers and mothers. METHODS: A cross-sectional research design was used to study a sample of 70 parent dyads. Instruments used were the Basic Information Form, Parenting Stress Index Short Form (PSI-SF), Parenting Self-efficacy Scale (PSE Scale), and World Health Organization Quality of Life-BREF Taiwan version (WHOQOL BREF). RESULTS: (1) Participants had a moderate level of QoL, PS, and PSE. (2) The PS of participants was significantly and negatively correlated with both QoL and PSE while their PSE was significantly and positively correlated with QoL. (3) The PSE of the fathers completely mediated the effects of PS on their QoL (p < .001), accounting for 62.2% of observed variation, while the PSE of the mothers partially mediated the effects of PS on their QoL (p < .05), accounting for 59.5% of observed variation. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: PSE was identified as the mediator between PS and QoL in both fathers and mothers. The PSE of the fathers completely mediated the effect of PS on QoL, while the PSE of the mothers partially mediated the effect of PS on QoL. Further research that explores the factors that affect the QoL of parents and then uses the results to develop interventions to enhance the PSE of parents, especially fathers, is recommended. PMID- 27699739 TI - [The Decision-Making Processes in Taiwanese Women With Repeat Caesarean Deliveries]. AB - BACKGROUND: Repeat caesarean delivery (RCD) ranks as the top reason for the high caesarean rates in Taiwan. More than 90% of Taiwanese women who have had a previous caesarean delivery chose RCD following their next pregnancy. PURPOSE: To explore the decision-making processes regarding RCD in Taiwanese women. METHODS: A qualitative approach with grounded theory was used to conduct this research. Participants were recruited from a private medical centre in northern Taiwan. Methods of data collection include in-depth interviews, observation, and field notes. Constant comparative analytical techniques were employed for data analysis. RESULTS: A total of 16 women chose RCD. Ensuring the well-being of mother and fetus was the core theme. Women's decisions were influenced by both internal factors (previous negative experience of birth, concern about uterine rupture, fixing the scar of previous caesarean and current pregnancy situation) and external factors (obstetrician's recommendation, the experience of female significant others, an inaccurate information from internet and the unconditional financial coverage from Health National Insurance). Decision-making processes involved searching information regarding mode of birth, evaluating vaginal birth risk, trusting obstetricians' professional judgment, and a lack of progress during the course of labour. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The well being of mother and fetus is the major concern affecting mothers' decisions regarding RCD. The majority of Taiwanese women participate passively in the decision-making process regarding their options for mode of birth. In the present study, women choices were primarily guided by reducing the risk of uterine rupture. Hospitals should reduce unnecessary induction interventions. Obstetricians should inform women of the risks and benefits of various birth modes. The government could establish a website that provides a clear explanation of the criteria for the government to financially cover the costs of RCD in order to assist women to make optimal birth choices. PMID- 27699740 TI - [The Perspectives and Expectations of New Nursing Graduates Regarding the Hospital-Based Nursing Students Scholarship]. AB - BACKGROUND: The hospital-based scholarship is a relatively recent incentive used by hospitals to recruit new nursing graduates. Few studies have explored the impact of these scholarship programs on hospital recruitment. PURPOSE: To explore the perspectives and expectations of new nursing graduates on the application of a hospital-based scholarship for nursing students. METHODS: This study used a qualitative research approach. Purposive sampling was used to recruit 20 new nursing graduates from one university in northern Taiwan in 2013. Content analysis was applied to analyze the data. RESULTS: Two themes were identified by participants who had applied for a hospital-based scholarship: "aspire to be a nursing-scholarship recipient and work towards this aspiration" and "look forward to receiving a nursing-scholarship and imagine possible features of the future life." One theme was identified by participants who had not applied for a hospital-based scholarship: "agree with the policy of hospital-based scholarship but resist the restrictions on their life." CONCLUSIONS / IMPLICATIONS FOR PRACTICE: Although both groups agreed that the scholarship program helped relieve financial stresses, participants who had applied for the scholarship tended to hold positive and aggressive attitudes towards the nursing scholarship. Conversely, participants who had not applied for the scholarship did so due to the perceived conflicts between the scholarship and their career plans. It is recommended to consider providing career-planning assistance to new graduates and to arrange that students who sign a scholarship contract have their clinical practice in their working unit in order to improve adaptation. PMID- 27699742 TI - [Comparison of Stages of Physical Activity Among Nurses, Physicians, and Allied Healthcare Professionals]. AB - BACKGROUND: Despite the fact that regular physical activity is known to improve physical health and reduce absenteeism and perceived job strain, healthcare professionals currently perform inadequate physical activity. PURPOSE: To understand and compare the differences in stages of physical activity among nurses, physicians, and allied healthcare professionals. METHODS: A cross sectional questionnaire was used to survey nurses, physicians, and allied healthcare professionals who worked at four branches of a hospital in Taiwan. Data were collected using the physical activity stage of change questionnire. Data were analyzed using descriptive analysis, Chi-square test of homogeneity of proportions and a posteriori comaparisons, and multinominal logistic regression analysis. RESULTS: Of the 3,260 questionnaires administrated, 2,001 valid questionnaires were returned for an effective response rate of 61.4%. In total, 1,497 (74.8%) of the nurses, 241 (12.0%) of the physicians, and 263 (13.1%) of the allied healthcare professionals completed the questionnaire. The results revealed that most of the physicans and allied healthcare professionals were in the preparation stage, while most of the nurses were in the precontemplation stage. Multinominal logistic regression analyses showed that, using the precontemplation stage as a reference value, the odds of being in the contemplation stage were lower among participants who were nurses or male or who had a master's or doctoral degree (p < .05). Further, the odds of being in the preparation stage were lower among nurses (p < .01). The odds of being in the maintenance stage were higher among participants that: lived in the Taitung area, were male, or were single (p < .01). CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The findings provide valuable references for future hospital leaders to develop effective individual physical activity programs for healthcare professionals. PMID- 27699741 TI - [The Association Between Multimorbidity and Medication Non-Adherence in Elderly With Hypertension in Western China]. AB - BACKGROUND: The prevalence of hypertension increases with aging. Medication non adherence is an important reason for the failure to control hypertension effectively, which increases the risks of cardiovascular and cerebrovascular incidents and of mortality. Multimorbidity is common among the elderly and has become a WHO-supported priority of research worldwide. While recent research suggests an association between multimorbidity and medication non-adherence, the results are not yet conclusive. PURPOSE: The present study describes the condition of medication non-adherence and multimorbidity among a population of elderly with hypertension in western China and explores the extent of the association between multimorbidity and medication non-adherence. METHODS: A cross sectional design with multi-stage sampling was used to recruit 1,316 elderly with hypertension from nine community health centers in the cities of Chengdu, Chongqing, and Urumqi. Data were collected using the study questionnaire and analyzed using the mean, percentage, independent samples t test, Chi-square test, Kruskal-Wallis H test, and binary logistic regression. RESULTS: The prevalence of medication non-adherence was 28.7%, and the prevalence of multimorbidity was 77.0%. Binary logistic regression analysis found the number of comorbidities to be a predictor of antihypertensive drug non-adherence, with those elderly with three (OR = 1.742, 95% CI [1.017, 2.984], four (OR = 2.601, 95% CI [1.489, 4.544] and more than five (OR = 3.262, 95% CI [1.839, 5.788] chronic conditions at significantly higher risk of non-adherence than their peers with no comorbidities. Other associated factors included poor health behaviors (OR = 1.715, 95% CI [1.263, 2.330] and region of residence. CONCLUSIONS: A positive association was found between medication non-adherence and the number of comorbidities in elderly with hypertension. This suggests the need for closer monitoring of the antihypertensive-drug prescription adherence of elderly with multiple chronic conditions and for further research to explore the measures that are necessary to improve medication adherence in this population. PMID- 27699743 TI - [Preventing Facial Pressure Injuries in Patients Who Use Noninvasive Positive Pressure Ventilators: The Efficiency of Dressings]. AB - BACKGROUND: Noninvasive positive pressure ventilation (NPPV) provides ventilation without tracheal intubation. Facial pressure injury is a recognized complication of this technique, making the prevention of facial pressure injuries an important issue for NPPV patients. PURPOSE: The present study compared the effects of foam dressing and hydrocolloid dressing in preventing facial pressure injuries in NPPV patients. METHODS: A randomized clinical trial was used to evaluate participants that were referred from the intensive care unit of a medical center in eastern Taiwan. Participants were randomized into two groups: the foam dressing group and the hydrocolloid dressing group. Statistics used in analysis were: analysis mean, standard deviation, chi-square, independent t-test, and the generalized estimating equation. RESULTS: Sixty participants were enrolled as participants. The incidence rate of facial pressure injury was 11.7% (7/60). No significant difference was found between the two groups in terms of duration of NPPV use, incidence of facial pressure injury, and occurrence time of facial pressure injury. However, the hydrocolloid dressing group had a higher usage amount than the foam dressing group (p < .05). CONCLUSIONS: Foam and hydrocolloid dressings are both helpful in preventing facial pressure injury when used in conjunction with regular skin assessments. PMID- 27699744 TI - [Factors Related to the Unplanned 90-Day Readmission Rate Among Elderly at a Geriatric Medicine Center]. AB - BACKGROUND: Unplanned readmissions increase healthcare utilization rates and healthcare costs. The Taiwan Healthcare Indicator Series regards the rate of hospital readmission as an important indicator of inpatient-care quality. The elderly face a higher risk of unplanned readmission due to elderly-specific health and disease characteristics such as deteriorating body functions and the relatively high incidence of complications after the treatment of acute diseases. PURPOSE: To explore the factors that relate to the unplanned readmission of elderly within 90 days of discharge at a geriatric medical center. METHODS: We retrospectively reviewed the medical records of inpatients aged >=65 years who had been admitted between January 2013 and December 2014. Related factors that affected the rate of unplanned readmission within 90 days of discharge were screened and analyzed using the chi-squared test and logistic regression analysis. RESULTS: The 90-day unplanned readmission rate was 20.3%. Factors that were found to relate to unplanned readmissions were: emergency room admission (88.7%), lack of regular outpatient follow-up (60.4%), cerebrovascular incidents (43.4%), osteoporosis (32.1%), gastrointestinal diseases (45.3%), and a hemoglobin level < 10.0 mg/dL (35.8%). CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The results of the present study may help the healthcare team better understand the factors that affect unplanned readmission in the elderly. We suggest that these teams provide timely health education for elderly, integrative healthcare for chronic diseases, and appropriate nutritional supplements in order to reduce unplanned readmissions. PMID- 27699745 TI - [Community Integrated Support Centers: The Experience of Hachioji, Tokyo, Japan]. AB - The proportion of elderly in Taiwan reached 11.99% of the population in 2014. Further, Taiwan is expected to become a super-aged society, as defined by the United Nations, in 2025. Elderly and long-term care needs have increased dramatically and long-term care (LTC) has become an increasingly important focus of policymaking. Japan, already a super-aged society, enacted LTC insurance in 2000 and has since implemented comprehensive LTC services nationwide. This article describes the evolution of the LTC insurance plan in Japan and the function of the Community Inclusive Care System. The latter integrates medical care, homecare services, LTC services, living support, and Community Integrated Support Centers with public-health nurses, social workers, and care managers in order to facilitate the construction of services that enhance aging in place. The authors hope that learning from Japan's experience in developing LTC will facilitate the future development of LTC services in Taiwan.

Diabetes affects patients not only in terms of physical health but also in terms of mental health. Furthermore, the medical costs that are associated with diabetes are considerable. Many countries have developed integrated care models for the treatment of diabetes and pay particular attention to assisting patients that require complicated care. Evidence from empirical studies shows that the integrated care of diabetes reduces complications, increases patients' health literacy, and decreases medical costs. Accordingly, integrated care has been applied to the treatment and care of diabetes patients. In the integrated care model, patients not only receive multidisciplinary care during hospitalization but also receive medical services after their return to the community. There has been a dearth of scholarly discussions in Taiwan related to the integrated care of diabetes. Therefore, we present in this paper the concept of integrated diabetes care and the role of the advanced practice nurse (APN) in the multidisciplinary model. It is hoped that this introduction provides practical insights for healthcare professionals into the essence of integrated care.

AB - Human epidermal growth factor receptor (HER2)-positive breast cancer is associated with a more aggressive disease and poor prognosis. The development of trastuzumab, a HER2-targeted agent, has changed the paradigm of HER2-positive breast cancer treatment and improved survival rates dramatically. However, metastatic HER2-positive breast cancer patients eventually develop resistance to this treatment regimen eventually. A new anti-HER2 antibody-drug conjugate, Trastuzumab emtansine (T-DM1), has been shown to improve treatment efficacy. However, side effects that differ from trastuzumab, including thrombocytopenia, liver dysfunction, fatigue, cardiotoxicity, pneumonitis, and peripheral neuropathy, may occur. Clinical nurses must understand the mechanism of this new agent and be aware of the symptoms and signs related to its side effects. Furthermore, clinical nurses should understand the varying degrees of these side effects, their probable causes, and the potential approaches to their management. Finally, clinical nurses must understand how to administer this agent in order to ensure patient safety. Understanding the side effects of T-DM1 and their management will help elevate nursing quality and caring efficacy.

Exposure of the skin surrounding the gastrostomy tube to moisture or chemical irritants may cause moisture associated skin damage (MASD) and seriously affect the patient's quality of life. This case study describes a nursing experience with gastrostomy leakage that resulted in MASD. An assessment conducted from July 29, 2015 to August 20, 2015 revealed that heavy gastronomy leakage had caused extensive skin erosion, ulceration, hyperplasia, and superficial infection. Simultaneously, the patient was required to conduct complex stoma care, which resulted in physical and psychological exhaustion. Changes in traditional tube and wound care were discussed on multiple occasions with an interdisciplinary healthcare team. Based on the evidence-based literature, we provide gastrostomy and MASD management strategies. Through team collaboration, we prevented gastric contents from contacting the patient's skin directly, improved patient comfort, controlled effluent and skin infections, maintained fluid and electrolyte balances, and acce lerated the healing of the damaged skin. We recommend that healthcare professionals caring for patients with gastrostomy leakage be provided with early skin protection programs to learn the standard methods for identifying and correcting leakage factors, containing effluent, and adequately stabilizing the gastrostomy tube in order to reduce the impact on the patient's quality of life. In addition, patient education on tube and skin care should be provided to prevent the reoccurrence of complications.

AB - INTRODUCTION: The perception of colour is one of the visual functions affected by optic neuritis. Most of the tests currently available for evaluating dichromatism are based on assessing the hue, but no clinical studies have been conducted to investigate the formation of afterimages on the retina of these patients. AIMS: To evaluate the dichromatism acquired in demyelinating optic neuritis by means of the formation of afterimages on the retina. SUBJECTS AND METHODS: This is an observation-based, cross-sectional, case-control study. The cases are patients with at least one bout of optic neuritis and confirmed multiple sclerosis. A healthy age- and sex-paired control was selected for each case. The main variable is the capacity to see afterimages after saturation of the retinal photoreceptor cells. A specific computer application was developed to evaluate this phenomenon. RESULTS: The sample consisted of 30 cases and 30 controls (63% females; mean age: 33 years; range: 18-48 years). The cases showed less probability of seeing the afterimage (36.6% of the cases, while none of the controls failed to see an afterimage) and, if it was seen, it remained for less time. The ROC curve shows a sensitivity of 86.3% and a specificity of 83.3%. The odds ratio was 5 (95% confidence interval: 2.21-11.3) for the probability of seeing the afterimage in controls versus cases. CONCLUSIONS: Patients with at least one episode of optic neuritis presented a lower capacity to observe afterimages. The test is therefore useful in the assessment and follow-up of functional damage in demyelinating optic neuropathies. PMID- 27699750 TI - [Frequency of single nucleotide polymorphisms and alpha-synuclein haplotypes associated with sporadic Parkinson's disease in the Mexican population]. AB - INTRODUCTION: Parkinson's disease (PD) is a common neurodegenerative disease which begins in adulthood. Its incidence in Mexico is estimated to be 40-50 cases per 100,000 inhabitants/year and is the fourth reason for medical care in the National Institute of Neurology and Neurosurgery. The protein alpha-synuclein, SNCA, plays a key role in the pathology of PD, and its polymorphisms have been associated with an increased risk of developing the disease. AIM: To evaluate the risk of PD represented by the polymorphisms rs2619364, rs2619363, rs2736990, rs7684318, rs17016074, rs356219, rs356220 and rs356203 of SNCA in a sample of Mexican subjects. SUBJECTS AND METHODS: Altogether 171 patients diagnosed with PD and 171 gender- and age-paired controls were assessed by means of real-time polymerase chain reaction, and a statistical analysis was performed to determine the association between the polymorphisms and the disease. RESULTS: The SNCA variants rs356220, rs356203, rs7684318 and rs2736990 were associated with the disease and form two haplotypes with a high risk of developing sporadic PD in the Mexican population. CONCLUSIONS: Variations in SNCA are a risk factor for the development of PD and can act as specific genetic biomarkers as a diagnostic support tool in sporadic PD for Mexican mestizo patients. PMID- 27699751 TI - [Diagnostic, prognostic and therapeutic implications of transcranial color-coded duplex sonography in acute ischemic stroke: TIBI and COGIF scores validation]. AB - AIM: To describe the information provided by transcranial color-coded duplex (TCCD) sonography for therapeutic decision-making in patients with acute ischemic stroke and to analyze the relationship between TCCD findings and the severity and prognosis of stroke. PATIENTS AND METHODS: TCCD performed within the six first hours after an acute ischemic stroke were analyzed in our institution. The presence of an arterial occlusion and its location were collected using TIBI (Thrombolysis in Brain Ischemia) and COGIF (Consensus on Grading Intracranial Flow Obstruction) criteria. Arterial recanalization within 24 hours after stroke was determined using TIBI and COGIF criteria. Favorable functional outcome was defined as a modified Rankin scale from 0 to 2 at three months. RESULTS: TCCD was performed in 104 patients, 85 were treated with intravenous thrombolysis. Arterial occlusion was detected in 79.8% of patients. The detection of arterial occlusion with TCCD allowed the selection for endovascular treatment in 23.1% of patients. Arterial occlusion was associated with a higher severity of stroke. Recanalization was detected in 44.1% using TIBI and 45.8% according to COGIF criteria. 80.8% of recanalized patients and only 39.5% of not recanalized had a favorable functional outcome at three months. Recanalization rate depended on the location of arterial occlusion. CONCLUSION: TCCD is a useful technique for the detection and location of arterial occlusion. It provides valuable prognostic information and allows selecting patients for endovascular recanalizing therapies. TIBI and COGIF scores provide a comparable information. PMID- 27699753 TI - [Early pharmacologic treatment with botulinum toxin A in post-stroke spasticity: consensus evidence-based recommendations]. AB - Spasticity is a common complication that occurs in those patients that have suffered a stroke. To identify those patients at high risk of having post-stroke spasticity and to start treatment at early stages would probably benefit the patient. The key aspects in the early management of post-stroke spasticity were review and the clinical implications and strength of evidences were also considered. The document drafted by the study coordinators was subsequently reviewed and then a validated document was developed. The experts recommend defining early treatment of spasticity as one that begins before the first three months after stroke. The panel considers very important to identify the risk factors associated with the onset of spasticity, since this might reduce its impact. Additionally, the most common conditions subsidiaries of early treatment of both upper and lower limb are defined. The panel recommends that the treatment with botulinum toxin A must only be given by specialists with experience in diagnosis and management of spasticity. In conclusion, the treatment of focal spasticity in the first three months after stroke is indicated in certain situations. These recommendations help to standardize the early management of post-stroke spasticity, with the consequent support to clinicians and patients.

AB - INTRODUCTION: Noonan syndrome is the most frequent of the congenital group of malformation syndromes caused by germline mutations that encode components of the RAS/MAPK pathway, termed RASopathies, one of the most frequent congenital genetic disorders in the clinical practice. Recently RIT1 mutations have been reported in patients with Noonan syndrome. CASE REPORT: A 7 years-old girl with a clinical diagnosis of Noonan syndrome, and with a hypertrophic cardiomyopathy included in her clinical manifestations, where a de novo heterozygous, probably pathogenic, novel mutation in RIT1, c.295T>C (p.Phe99Leu), has been identified. CONCLUSIONS: RIT1 shares homology with other RAS proteins and the expression of mutant alleles demonstrates a gain-of-function effect supporting a causative role in Noonan syndrome pathogenesis. Data suggest that the frequency of RIT1 mutations can be estimated as 3-5% in Noonan syndrome patients. These cases compared with Noonan patients harboring mutations in other genes are characterized by high frequency of prenatal abnormalities and hypertrophic cardiomyopathy, and lower frequencies of short stature and pectus abnormalities. We emphasize the importance of the novel identified genes in order to be included in the diagnostic panels. PMID- 27699754 TI - [Tarantism in Spain in the eighteen century: latrodectism and suggestion]. AB - INTRODUCTION: Tarantism is the disease caused by the bite of the tarantula, in which the music tarantella triggers an involuntary dance. It is known in Italy since the sixteenth century. AIM: To analyze the tarantism reported in Spain at the end of the eighteenth century, with special attention to its neurological aspects, and to propose its medical and psychopathological explanation. DEVELOPMENT: An epidemic of people affected by the tarantula bite occurred in Spain in 1782. Spanish doctors described appropriately the clinical effects, identical to those produced by the bite of the spider black widow (Latrodectus tredecimguttatus), which was at that time identified as a tarantula. The cases reported by Francisco Xavier Cid cured with the involuntary dance triggered by the tarantella, as was described in Italy since the sixteenth century. Our interpretation is that this curative effect of dance in Spain was induced by suggestion. In Spanish patients there were no behavioral disturbances, periodic recurrences or collective involvement as those reported by Italian authors, which suggest an hysterical phenomenon, probably a continuation of the dancing mania of the Middle Age. CONCLUSIONS: Tarantism reported in Spain in the eighteenth century includes two different phenomena: the systemic symptoms produced by the tarantula bite, which is actually latrodectism, and the curative effect of the tarantella, explained by suggestion. The psychiatric disturbances, with a hysterical nature, falsely associated to the tarantula bite, observed in Italy, were not present among the Spanish cases of tarantism in the eighteenth century.

Official document of the Spanish Sleep Society]. AB - One of the main objectives of the Spanish Sleep Society is to promote healthy sleep in both the general population and in health professionals. This document aims to conduct a review of the current scientific literature on sleep habits that can serve as the basis on which to establish a set of general recommendations, regarding healthy sleep, for use by the general population in Spain as well as to identify the main challenges faced by research into sleep habits. The document has been developed by a multidisciplinary team made up of members of the Spanish Sleep Society who are experts in paediatric sleep medicine, clinical neurophysiology, pulmonology, neurology, chronobiology, physiology and psychology. The existing scientific literature dealing with sleep habits in the general population was reviewed, and the following aspects were addressed: the current state of sleep habits in the Spanish population; a generic review of the optimum number of hours of sleep; the impact of the environmental setting (noise, temperature, illumination, etc.), hours of sleep, diet and sport, together with several specific sections for children and teenagers, shift-workers and drivers of different vehicles. The conclusions from all the aspects addressed in this document have resulted in a set of final general recommendations that will serve as a guide for the general population and health professionals. Likewise, the principal environmental challenges and future lines of research are also discussed. PMID- 27699759 TI - Severe sepsis in the ICU is often missing in hospital discharge codes. AB - BACKGROUND: Different International Classification of Diseases (ICD)-based code abstraction strategies have been used when studying the epidemiology of severe sepsis. The aim of this study was to compare three previously used ICD code abstraction strategies to the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) consensus criteria for severe sepsis, in a setting of intensive care patients. METHODS: All patients (>= 18 years of age) with severe sepsis according to the ACCP/SCCM criteria registered in the Swedish Intensive Care Registry (2005-2009) were included in the study. Using the Swedish National Patient Register, we investigated whether these patients fulfilled an ICD code compilation for severe sepsis at hospital discharge. RESULTS: Overall, 9271 patients with severe sepsis were registered in the Swedish Intensive Care Registry. A majority of these patients (55.4%) were discharged from the hospital with ICD codes that did not correspond to any of the ICD code compilations. A minority of patients (10.3%) were discharged with ICD codes corresponding to all three code abstraction strategies applied. Overall, the proportion of patients discharged with ICD codes corresponding to the criteria of Angus et al. was 15.1%, to the criteria of Flaatten was 39.8%, and to the criteria of Martin et al. was 16.0%. CONCLUSIONS: A majority of patients with severe sepsis according to the ACCP/SCCM criteria were not discharged with ICD codes corresponding to the ICD code abstraction strategies; thus, the abstraction strategies did not identify the correct patients. PMID- 27699760 TI - Intensity of continuous renal replacement therapy for acute kidney injury. AB - BACKGROUND: Acute kidney injury (AKI) is a common condition among patients in intensive care units (ICU), and is associated with substantial morbidity and mortality. Continuous renal replacement therapy (CRRT) is a blood purification technique used to treat the most severe forms of AKI but its effectiveness remains unclear. OBJECTIVES: To assess the effects of different intensities (intensive and less intensive) of CRRT on mortality and recovery of kidney function in critically ill AKI patients. SEARCH METHODS: We searched Cochrane Kidney and Transplant's Specialised Register to 9 February 2016 through contact with the Information Specialist using search terms relevant to this review. Studies contained in the Specialised Register are identified through search strategies specifically designed for CENTRAL, MEDLINE, and EMBASE; handsearching conference proceedings; and searching the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. We also searched LILACS to 9 February 2016. SELECTION CRITERIA: We included all randomised controlled trials (RCTs). We included all patients with AKI in ICU regardless of age, comparing intensive (usually a prescribed dose >=35 mL/kg/h) versus less intensive CRRT (usually a prescribed dose < 35 mL/kg/h). For safety and cost outcomes we planned to include cohort studies and non-RCTs. DATA COLLECTION AND ANALYSIS: Data were extracted independently by two authors. The random-effects model was used and results were reported as risk ratios (RR) for dichotomous outcomes and mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI). MAIN RESULTS: We included six studies enrolling 3185 participants. Studies were assessed as being at low or unclear risk of bias. There was no significant difference between intensive versus less intensive CRRT on mortality risk at day 30 (5 studies, 2402 participants: RR 0.88, 95% CI 0.71 to 1.08; I2 = 75%; low quality of evidence) or after 30 days post randomisation (5 studies, 2759 participants: RR 0.92, 95% CI 0.80 to 1.06; I2 = 65%; low quality of evidence). There were no significant differences between intensive versus less intensive CRRT in the numbers of patients who were free of RRT after CRRT discontinuation (5 studies, 2402 participants: RR 1.12, 95% CI 0.91 to 1.37; I2 = 71%; low quality of evidence) or among survivors at day 30 (5 studies, 1415 participants: RR 1.03, 95% CI 0.96 to 1.11; I2 = 69%; low quality of evidence) and day 90 (3 studies, 988 participants: RR 0.98, IC 95% 0.94 to 1.01, I2 = 0%; moderatequality of evidence). There were no significant differences between intensive and less intensive CRRT on the number of days in hospital (2 studies, 1665 participants): MD -0.23 days, 95% CI -3.35 to 2.89; I2 = 8%; low quality of evidence) and the number of days in ICU (2 studies, 1665 participants: MD -0.58 days, 95% CI -3.73 to 2.56, I2 = 19%; low quality of evidence). Intensive CRRT increased the risk of hypophosphataemia (1 study, 1441 participants: RR 1.21, 95% CI 1.11 to 1.31; high quality evidence) compared to less intensive CRRT. There was no significant differences between intensive and less intensive CRRT on numbers of patients who experienced adverse events (3 studies, 1753 participants: RR 1.08, 95% CI 0.73 to 1.61; I2 = 16%; moderate quality of evidence). In the subgroups analysis by severity of illness and by aetiology of AKI, intensive CRRT would seem to reduce the risk mortality (2 studies, 531 participants: RR 0.73, 95% CI 0.61 to 0.88; I2 = 0%; high quality of evidence) only in the subgroup of patients with post surgical AKI. AUTHORS' CONCLUSIONS: Based on the current low quality of evidence identified, more intensive CRRT did not demonstrate beneficial effects on mortality or recovery of kidney function in critically ill patients with AKI. There was an increased risk of hypophosphataemia with more intense CRRT. Intensive CRRT reduced the risk of mortality in patients with post-surgical AKI.

PMID- 27699761 TI - Strategies to improve the implementation of healthy eating, physical activity and obesity prevention policies, practices or programmes within childcare services. AB - BACKGROUND: Despite the existence of effective interventions and best-practice guideline recommendations for childcare services to implement policies, practices and programmes to promote child healthy eating, physical activity and prevent unhealthy weight gain, many services fail to do so. OBJECTIVES: The primary aim of the review was to examine the effectiveness of strategies aimed at improving the implementation of policies, practices or programmes by childcare services that promote child healthy eating, physical activity and/or obesity prevention. The secondary aims of the review were to:1. describe the impact of such strategies on childcare service staff knowledge, skills or attitudes;2. describe the cost or cost-effectiveness of such strategies;3. describe any adverse effects of such strategies on childcare services, service staff or children;4. examine the effect of such strategies on child diet, physical activity or weight status. SEARCH METHODS: We searched the following electronic databases on 3 August 2015: the Cochrane Central Register of Controlled trials (CENTRAL), MEDLINE, MEDLINE In Process, EMBASE, PsycINFO, ERIC, CINAHL and SCOPUS. We also searched reference lists of included trials, handsearched two international implementation science journals and searched the World Health Organization International Clinical Trials Registry Platform (www.who.int/ictrp/) and ClinicalTrials.gov (www.clinicaltrials.gov). SELECTION CRITERIA: We included any study (randomised or non-randomised) with a parallel control group that compared any strategy to improve the implementation of a healthy eating, physical activity or obesity prevention policy, practice or programme by staff of centre-based childcare services to no intervention, 'usual' practice or an alternative strategy. DATA COLLECTION AND ANALYSIS: The review authors independently screened abstracts and titles, extracted trial data and assessed risk of bias in pairs; we resolved discrepancies via consensus. Heterogeneity across studies precluded pooling of data and undertaking quantitative assessment via meta-analysis. However, we narratively synthesised the trial findings by describing the effect size of the primary outcome measure for policy or practice implementation (or the median of such measures where a single primary outcome was not stated). MAIN RESULTS: We identified 10 trials as eligible and included them in the review. The trials sought to improve the implementation of policies and practices targeting healthy eating (two trials), physical activity (two trials) or both healthy eating and physical activity (six trials). Collectively the implementation strategies tested in the 10 trials included educational materials, educational meetings, audit and feedback, opinion leaders, small incentives or grants, educational outreach visits or academic detailing. A total of 1053 childcare services participated across all trials. Of the 10 trials, eight examined implementation strategies versus a usual practice control and two compared alternative implementation strategies. There was considerable study heterogeneity. We judged all studies as having high risk of bias for at least one domain.It is uncertain whether the strategies tested improved the implementation of policies, practices or programmes that promote child healthy eating, physical activity and/or obesity prevention. No intervention improved the implementation of all policies and practices targeted by the implementation strategies relative to a comparison group. Of the eight trials that compared an implementation strategy to usual practice or a no intervention control, however, seven reported improvements in the implementation of at least one of the targeted policies or practices relative to control. For these trials the effect on the primary implementation outcome was as follows: among the three trials that reported score-based measures of implementation the scores ranged from 1 to 5.1; across four trials reporting the proportion of staff or services implementing a specific policy or practice this ranged from 0% to 9.5%; and in three trials reporting the time (per day or week) staff or services spent implementing a policy or practice this ranged from 4.3 minutes to 7.7 minutes. The review findings also indicate that is it uncertain whether such interventions improve childcare service staff knowledge or attitudes (two trials), child physical activity (two trials), child weight status (two trials) or child diet (one trial). None of the included trials reported on the cost or cost-effectiveness of the intervention. One trial assessed the adverse effects of a physical activity intervention and found no difference in rates of child injury between groups. For all review outcomes, we rated the quality of the evidence as very low. The primary limitation of the review was the lack of conventional terminology in implementation science, which may have resulted in potentially relevant studies failing to be identified based on the search terms used in this review. AUTHORS' CONCLUSIONS: Current research provides weak and inconsistent evidence of the effectiveness of such strategies in improving the implementation of policies and practices, childcare service staff knowledge or attitudes, or child diet, physical activity or weight status. Further research in the field is required. PMID- 27699763 TI - Has the twin rate after in vitro fertilisation really decreased in Australia?

AB - BACKGROUND: Non-nutritive sucking (NNS) is used during gavage feeding and in the transition from gavage to breast/bottle feeding in preterm infants to improve the development of sucking behavior and the digestion of enteral feedings. OBJECTIVES: To assess the effects of non-nutritive sucking on physiologic stability and nutrition in preterm infants. SEARCH METHODS: We used the standard search strategy of the Cochrane Neonatal Review group to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 1), MEDLINE via PubMed (1966 to 25 February 2016), Embase (1980 to 25 February 2016), and CINAHL (1982 to 25 February 2016). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials. SELECTION CRITERIA: Randomised controlled trials and quasi-randomised trials that compared non-nutritive sucking versus no provision of non-nutritive sucking in preterm infants. We excluded cross-over trials. DATA COLLECTION AND ANALYSIS: Two review authors assessed trial eligibility and risk of bias and undertook data extraction independently. We analysed the treatment effects in the individual trials and reported mean differences (MD) for continuous data, with 95% confidence intervals (CIs). We used a fixed-effect model in meta-analyses. We did not perform subgroup analyses because of the small number of studies related to the relevant outcomes. We used the GRADE approach to assess the quality of evidence. MAIN RESULTS: We identified 12 eligible trials enrolling a total of 746 preterm infants. Meta-analysis, though limited by data quality, demonstrated a significant effect of NNS on transition from gavage to full oral feeding (MD -5.51 days, 95% CI -8.20 to 2.82; N = 87), transition from start of oral feeding to full oral feeding (MD 2.15 days, 95% CI -3.12 to -1.17; N = 100), and the length of hospital stay (MD 4.59 days, 95% CI -8.07 to -1.11; N = 501). Meta-analysis revealed no significant effect of NNS on weight gain. One study found that the NNS group had a significantly shorter intestinal transit time during gavage feeding compared to the control group (MD -10.50 h, 95% CI -13.74 to -7.26; N = 30). Other individual studies demonstrated no clear positive effect of NNS on age of infant at full oral feeds, days from birth to full breastfeeding, rates and proportion of infants fully breastfeeding at discharge, episodes of bradycardia, or episodes of oxygen desaturation. None of the studies reported any negative outcomes. These trials were generally small and contained various methodological weaknesses including lack of blinding of intervention and outcome assessors and variability on outcome measures. The quality of the evidence on outcomes assessed according to GRADE was low to very low. AUTHORS' CONCLUSIONS: Meta-analysis demonstrated a significant effect of NNS on the transition from gavage to full oral feeding, transition from start of oral feeding to full oral feeding, and length of hospital stay. None of the trials reported any adverse effects. Well-designed, adequately powered studies using reliable methods of randomisation, concealment of treatment allocation and blinding of the intervention and outcome assessors are needed. In order to facilitate meta-analysis of these data, future research should involve outcome measures consistent with those used in previous studies.

PMID- 27699767 TI - Glucuronic Acid Epimerase (GLCE) Variant rs3865014 (A>G) Is Associated with BMI, Blood Hemoglobin, Hypertension, and Cerebrovascular Events, the TAMRISK Study. AB - Heparan sulfate proteoglycans modulate many physiological systems, and genes responsible for proteoglycan assembly and disassembly may affect their interaction. We sought to determine whether polymorphisms of the glucuronic acid epimerase (GLCE) rs3865014 and sulfatase-2 (SULF2) rs2281279, genes coding for enzymes participating in heparan sulfate side chain activity, associate with hypertension, selected cardiometabolic risk factors and cardiovascular events in the Tampere adult population cardiovascular risk study. A Finnish cohort of 339 subjects with diagnosed hypertension and 441 controls was analyzed. Samples were genotyped for GLCE rs3865014 (A>G) and SULF2 rs2281279 (T>C) polymorphisms using competitive allele-specific PCR (KASP) technique. Prevalence of ischemic heart diseases (I20-I25) and incidence of cerebrovascular diseases (I60-I69) and transient cerebral ischemic attacks (TIA) (G45) were followed up until the subjects were on the average 60 years old. GLCE rs3865014 G allele showed negative association with hypertension (p = 0.022), waist circumference (p = 0.032), BMI (p = 0.048), and positive association with hemoglobin (p = 0.029), low-density lipoprotein cholesterol (p = 0.031), and frequency of cerebrovascular events (p = 0.011). SULF2 rs2281279 showed no association with the studied parameters. The GLCE gene polymorphism rs3865014 appears to have biological relevance in human pathophysiology. PMID- 27699768 TI - Cross-cultural validity of standardized motor development screening and assessment tools: a systematic review. AB - AIM: To investigate whether standardized motor development screening and assessment tools that are used to evaluate motor abilities of children aged 0 to 2 years are valid in cultures other than those in which the normative sample was established. METHOD: This was a systematic review in which six databases were searched. Studies were selected based on inclusion/exclusion criteria and appraised for evidence level and quality. Study variables were extracted. RESULTS: Twenty-three studies representing six motor development screening and assessment tools in 16 cultural contexts met the inclusion criteria: Alberta Infant Motor Scale (n=7), Ages and Stages Questionnaire, 3rd edition (n=2), Bayley Scales of Infant and Toddler Development, 3rd edition (n=8), Denver Developmental Screening Test, 2nd edition (n=4), Harris Infant Neuromotor Test (n=1), and Peabody Developmental Motor Scales, 2nd edition (n=1). Thirteen studies found significant differences between the cultural context and normative sample. Two studies established reliability and/or validity of standardized motor development assessments in high-risk infants from different cultural contexts. Five studies established new population norms. Eight studies described the cross cultural adaptation of a standardized motor development assessment. INTERPRETATION: Standardized motor development assessments have limited validity in cultures other than that in which the normative sample was established. Their use can result in under- or over-referral for services.

AB - The PI3K-AKT-mTOR signaling cascade is activated in the majority of human cancers, and its activation also plays a key role in resistance to chemo and targeted therapeutics. In particular, in both breast and prostate cancer, increased AKT pathway activity is associated with cancer progression, treatment resistance and poor disease outcome. Here, we evaluated the activity of a novel allosteric AKT1/2 inhibitor, BAY 1125976, in biochemical, cellular mechanistic, functional and in vivo efficacy studies in a variety of tumor models. In in vitro kinase activity assays, BAY 1125976 potently and selectively inhibited the activity of full-length AKT1 and AKT2 by binding into an allosteric binding pocket formed by kinase and PH domain. In accordance with this proposed allosteric binding mode, BAY 1125976 bound to inactive AKT1 and inhibited T308 phosphorylation by PDK1, while the activity of truncated AKT proteins lacking the pleckstrin homology domain was not inhibited. In vitro, BAY 1125976 inhibited cell proliferation in a broad panel of human cancer cell lines. Particularly high activity was observed in breast and prostate cancer cell lines expressing estrogen or androgen receptors. Furthermore, BAY 1125976 exhibited strong in vivo efficacy in both cell line and patient-derived xenograft models such as the KPL4 breast cancer model (PIK3CAH1074R mutant), the MCF7 and HBCx-2 breast cancer models and the AKTE17K mutant driven prostate cancer (LAPC-4) and anal cancer (AXF 984) models. These findings indicate that BAY 1125976 is a potent and highly selective allosteric AKT1/2 inhibitor that targets tumors displaying PI3K/AKT/mTOR pathway activation, providing opportunities for the clinical development of new, effective treatments.

AB - BACKGROUND: Comprehensive diets do not require the exclusion of a specific provocative food or ingredient, but regulate the quantities of core components of foods such as vitamins, ions, proteins, carbohydrates, and fats. OBJECTIVES: To review the evidence supporting the use of comprehensive diets in the prevention of migraine and other headache disorders and to discuss the mechanisms through which food, and ingredients within foods and beverages might trigger attacks of headache METHODS: This represents Part 2 of a narrative review of the role of diet in the prevention of migraine and other headache disorders. A PubMed search was performed with the following search terms: "folate," "vitamin D," "low fat diet," "omega-3 and omega-6 fatty acid diet," "ketogenic diet," "Atkins diet," and "sodium." Each of these search terms was then crossreferenced with "headache" and "migraine" to identify relevant studies. Only studies that were written in English were included in this review. RESULTS: Low fat and high omega-3/low omega 6 fatty diets decrease the frequency of attacks of migraine and/or other headache disorders as demonstrated in two separate randomized controlled trials. A ketogenic diet was more effective than a standard diet in reducing the frequency of migraine in a single nonrandomized clinical study. An observation study found that dietary consumption of folate was inversely associated with the frequency of migraine attacks in persons with migraine with aura that have the C variant of the methylene tetrahydrofolate reductase gene. The mechanisms though which diets may precipitate headache include their effects on neuropeptides, neuro-receptors and ion channels, inflammation, sympathetic nervous system, release of nitric oxide, vasodilation, and cerebral glucose metabolism. CONCLUSIONS: Evidence exists to support the use of comprehensive diets in the prevention of migraine and other headache disorders. However, the results of these studies should be considered preliminary until replicated in larger randomized controlled clinical trials.

OBJECTIVES: To review the evidence supporting the hypothesis that specific foods or ingredients within foods and beverages trigger attacks of headache and/or migraine and to discuss the use of elimination diets in the prevention of headache disorders METHODS: This represents part 1 of a narrative review of the role of diet in the prevention of migraine and other headache disorders. A PubMed search was performed with the following search terms: "monosodium glutamate," "caffeine," "aspartame," "sucralose," "histamine intolerance syndrome," "tyramine," "alcohol," "chocolate," "nitrites," "IgG elimination diets," and "gluten." Each of these search terms was then cross-referenced with "headache" and "migraine" to identify relevant studies. Only studies that were written in English were included in this review. RESULTS: Caffeine withdrawal and administration of MSG (dissolved in liquid) has the strongest evidence for triggering attacks of headache as evidenced by multiple positive provocation studies. Aspartame has conflicting evidence with two positive and two negative provocation studies. Observational studies provide modest evidence that gluten- and histamine-containing foods as well as alcohol may precipitate headaches in subgroups of patients. Two of three randomized controlled trials reported that an elimination diet of IgG positive foods significantly decreased frequency of headache/migraine during the treatment as compared to baseline time period. CONCLUSIONS: Certain foods, beverages, and ingredients within foods may trigger attacks of headache and/or migraine in susceptible individuals. Elimination diets can prevent headaches in subgroups of persons with headache disorders. PMID- 27699781 TI - Can We Speak of Lack of Habituation in Visual Snow?

PMID- 27699783 TI - Factors that impact on the use of mechanical ventilation weaning protocols in critically ill adults and children: a qualitative evidence-synthesis. AB - BACKGROUND: Prolonged mechanical ventilation is associated with a longer intensive care unit (ICU) length of stay and higher mortality. Consequently, methods to improve ventilator weaning processes have been sought. Two recent Cochrane systematic reviews in ICU adult and paediatric populations concluded that protocols can be effective in reducing the duration of mechanical ventilation, but there was significant heterogeneity in study findings. Growing awareness of the benefits of understanding the contextual factors impacting on effectiveness has encouraged the integration of qualitative evidence syntheses with effectiveness reviews, which has delivered important insights into the reasons underpinning (differential) effectiveness of healthcare interventions. OBJECTIVES: 1. To locate, appraise and synthesize qualitative evidence concerning the barriers and facilitators of the use of protocols for weaning critically-ill adults and children from mechanical ventilation;2. To integrate this synthesis with two Cochrane effectiveness reviews of protocolized weaning to help explain observed heterogeneity by identifying contextual factors that impact on the use of protocols for weaning critically-ill adults and children from mechanical ventilation;3. To use the integrated body of evidence to suggest the circumstances in which weaning protocols are most likely to be used. SEARCH METHODS: We used a range of search terms identified with the help of the SPICE (Setting, Perspective, Intervention, Comparison, Evaluation) mnemonic. Where available, we used appropriate methodological filters for specific databases. We searched the following databases: Ovid MEDLINE, Embase, OVID, PsycINFO, CINAHL Plus, EBSCOHost, Web of Science Core Collection, ASSIA, IBSS, Sociological Abstracts, ProQuest and LILACS on the 26th February 2015. In addition, we searched: the grey literature; the websites of professional associations for relevant publications; and the reference lists of all publications reviewed. We also contacted authors of the trials included in the effectiveness reviews as well as of studies (potentially) included in the qualitative synthesis, conducted citation searches of the publications reporting these studies, and contacted content experts.We reran the search on 3rd July 2016 and found three studies, which are awaiting classification. SELECTION CRITERIA: We included qualitative studies that described: the circumstances in which protocols are designed, implemented or used, or both, and the views and experiences of healthcare professionals either involved in the design, implementation or use of weaning protocols or involved in the weaning of critically-ill adults and children from mechanical ventilation not using protocols. We included studies that: reflected on any aspect of the use of protocols, explored contextual factors relevant to the development, implementation or use of weaning protocols, and reported contextual phenomena and outcomes identified as relevant to the effectiveness of protocolized weaning from mechanical ventilation. DATA COLLECTION AND ANALYSIS: At each stage, two review authors undertook designated tasks, with the results shared amongst the wider team for discussion and final development. We independently reviewed all retrieved titles, abstracts and full papers for inclusion, and independently extracted selected data from included studies. We used the findings of the included studies to develop a new set of analytic themes focused on the barriers and facilitators to the use of protocols, and further refined them to produce a set of summary statements. We used the Confidence in the Evidence from Reviews of Qualitative Research (CERQual) framework to arrive at a final assessment of the overall confidence of the evidence used in the synthesis. We included all studies but undertook two sensitivity analyses to determine how the removal of certain bodies of evidence impacted on the content and confidence of the synthesis. We deployed a logic model to integrate the findings of the qualitative evidence synthesis with those of the Cochrane effectiveness reviews. MAIN RESULTS: We included 11 studies in our synthesis, involving 267 participants (one study did not report the number of participants). Five more studies are awaiting classification and will be dealt with when we update the review.The quality of the evidence was mixed; of the 35 summary statements, we assessed 17 as 'low', 13 as 'moderate' and five as 'high' confidence. Our synthesis produced nine analytical themes, which report potential barriers and facilitators to the use of protocols. The themes are: the need for continual staff training and development; clinical experience as this promotes felt and perceived competence and confidence to wean; the vulnerability of weaning to disparate interprofessional working; an understanding of protocols as militating against a necessary proactivity in clinical practice; perceived nursing scope of practice and professional risk; ICU structure and processes of care; the ability of protocols to act as a prompt for shared care and consistency in weaning practice; maximizing the use of protocols through visibility and ease of implementation; and the ability of protocols to act as a framework for communication with parents. AUTHORS' CONCLUSIONS: There is a clear need for weaning protocols to take account of the social and cultural environment in which they are to be implemented. Irrespective of its inherent strengths, a protocol will not be used if it does not accommodate these complexities. In terms of protocol development, comprehensive interprofessional input will help to ensure broad-based understanding and a sense of 'ownership'. In terms of implementation, all relevant ICU staff will benefit from general weaning as well as protocol specific training; not only will this help secure a relevant clinical knowledge base and operational understanding, but will also demonstrate to others that this knowledge and understanding is in place. In order to maximize relevance and acceptability, protocols should be designed with the patient profile and requirements of the target ICU in mind. Predictably, an under-resourced ICU will impact adversely on protocol implementation, as staff will prioritize management of acutely deteriorating and critically-ill patients.

AB - This study reports on the association of genetic variants selected from previous genome-wide association studies for type 2 diabetic nephropathy in south Indians. Eight variants were genotyped in 601 type 2 diabetic subjects without nephropathy (DM) and 583 type 2 diabetic subjects with nephropathy (DN) by MassARRAY. The minor allele frequencies of rs11643718 SLC12A3 variant and rs741301 ELMO1 variant were significantly different between DM and DN groups (P = 0.029 and 0.016, respectively). A combined analysis showed that the subjects carrying the risk genotypes of both these variants (GG of rs11643718 + AG/AA of rs741301) had a significant association with DN with an odds ratio [adjusted for age, sex, Body Mass Index (BMI), HbA1c, and systolic Blood Pressure (BP)] of 1.73 (1.30-2.30, P = 1.72 * 10-4 ) as compared to subjects carrying all other genotype combinations. This is the first study to report a significant association of the SLC12A3 rs11643718 and ELMO1 rs741301 (Single nucleotide Polymorphism) SNPs with diabetic nephropathy in south Indians.

This review provides a summary of this line of research, examines variables contributing to participant preference and performance under different response-reinforcer arrangements, and discusses limitations and areas for future research. PMID- 27699788 TI - Temperature-dependent autoimmunity mediated by chs1 requires its neighboring TNL gene SOC3. AB - Toll/interleukin receptor (TIR)-nucleotide binding site (NB)-type (TN) proteins are encoded by a family of 21 genes in the Arabidopsis genome. Previous studies have shown that a mutation in the TN gene CHS1 activates the activation of defense responses at low temperatures. However, the underlying molecular mechanism remains unknown. To genetically dissect chs1-mediated signaling, we isolated genetic suppressors of chs1-2 (soc). Several independent soc mutants carried mutations in the same TIR-NB-leucine-rich repeat (LRR) (TNL)-encoding gene SOC3, which is adjacent to CHS1 on chromosome 1. Expression of SOC3 was upregulated in the chs1-2 mutant. Mutations in six soc3 alleles and downregulation of SOC3 by an artificial microRNA construct fully rescued the chilling sensitivity and defense defects of chs1-2. Biochemical studies showed that CHS1 interacted with the NB and LRR domains of SOC3; however, mutated chs1 interacted with the TIR, NB and LRR domains of SOC3 in vitro and in vivo. This study reveals that the TN protein CHS1 interacts with the TNL protein SOC3 to modulate temperature-dependent autoimmunity.

AB - AIM: The aim of this article is to describe our experience in operating a capacity-building programme, the Korea International Cooperation Project, for global nursing leaders from developing countries, held during the International Council of Nurses (ICN) Conference in 2015 in Seoul, Korea. BACKGROUND: Globalization points to the importance of global leadership among nursing leaders. In accordance with the theme of 'Global Citizen, Global Nursing' at the ICN conference in 2015, a capacity-building programme for nursing leaders of developing countries was implemented. INTRODUCTION: The global nursing leadership programme shared experiences during the preparation and operation of the conference. To prepare the programme, this paper describes selecting participants, working with invitation lists from 30 countries, and recruiting and training volunteers. The operation of the programme, orientation, organizing tailored programmes for participant groups, addressing unexpected issues and evaluating the programme are described. IMPLICATIONS FOR NURSING POLICY: ICN could implement capacity-building programmes for nursing leaders of developing countries during its ICN conference for the nursing society. A programme tailored for each continent with similar sociocultural backgrounds and health issues would provide chances for collaboration and networking. A policy to compile global nursing indicators should be developed. This would allow nursing leaders to learn about the strengths and weaknesses of global nursing and provide evidence for collaboration. CONCLUSION: The programme was successful in introducing and broadening global perspectives of participants on health and education as well as building a network among leaders and next-generation leaders in participating countries for future cooperation and collaboration.

AB - In testing the hypothesis of Alzheimer's disease (AD)-like pathology in late stage traumatic brain injury (TBI), we evaluated AD pathological markers in late stage TBI model. Sprague-Dawley male rats were subjected to moderate controlled cortical impact (CCI) injury, and 6 months later euthanized and brain tissues harvested. Results from H&E staining revealed significant 33% and 10% reduction in the ipsilateral and contralateral hippocampal CA3 interneurons, increased MHCII-activated inflammatory cells in many gray matter (8-20-fold increase) and white matter (6-30-fold increased) regions of both the ipsilateral and contralateral hemispheres, decreased cell cycle regulating protein marker by 1.6- and 1-fold in the SVZ and a 2.3- and 1.5-fold reductions in the ipsilateral and contralateral dentate gyrus, diminution of immature neuronal marker by two- and onefold in both the ipsilateral and contralateral SVZ and dentate gyrus, and amplified amyloid precursor protein (APP) distribution volumes in white matter including corpus callosum, fornix, and internal capsule (4-38-fold increase), as well as in the cortical gray matter, such as the striatum hilus, SVZ, and dentate gyrus (6-40-fold increase) in TBI animals compared to controls (P's < 0.001). Surrogate AD-like phenotypic markers revealed a significant accumulation of phosphorylated tau (AT8) and oligomeric tau (T22) within the neuronal cell bodies in ipsilateral and contralateral cortex, and dentate gyrus relative to sham control, further supporting the rampant neurodegenerative pathology in TBI secondary cell death. These findings indicate that AD-like pathological features may prove to be valuable markers and therapeutic targets for late stage TBI. J. Cell. Physiol. 232: 665-677, 2017.

AB - BACKGROUND/AIM: The first evidence-based Clinical Practice Guidelines and Principles of Care for People with Dementia in Australia have been released. The Guidelines detail a number of important evidence-based recommendations for occupational therapists. The aim of this paper is (1) to provide an overview of Guideline development, and (2) to describe the evidence supporting a recommendation for occupational therapy. Common characteristics of effective occupational therapy programmes for people with dementia are described. METHODS: Guideline development involved adaptation of existing high-quality guidelines developed overseas and 17 systematic reviews to ensure that the most recent high quality evidence was included. One of the systematic reviews involved examining the evidence for interventions to promote independence in people with dementia. Specifically, we looked at the evidence for occupational therapy and its effect on activities of daily living, quality of life and carer impact. RESULTS: A total of 109 recommendations are included in the Guidelines. Occupational therapy was found to significantly increase independence in activities of daily living and improve quality of life. Effective occupational therapy programmes involve: environmental assessment, problem solving strategies, carer education and interactive carer skills training. CONCLUSION: Occupational therapists working with people with dementia in community settings should ensure that their time is spent on those aspects of intervention that are shown to be effective. PMID- 27699795 TI - Technology Optimization of Lysozyme's Fresh Maintaining Effect on Apple. AB - Lysozyme is a kind of alkaline globin, which functions well in the degradation of the cell wall of microbe. Currently, lysozyme is widely used in various fields, such as medicine, fruit, and vegetable industry, dairy industry, and so on. Therefore, the exploitation and utilization of lysozyme is of significant economic benefit. Taking apple as material, weight loss ratio and reducing sugar content as objectives, this paper studied the fresh-keeping effect of lysozyme. Influential factors, lysozyme concentration, soaking time, modified temperature, and reaction time were discussed in detail. The results showed that reducing sugar content was 2.043% and the weight loss ratio was the minimum in the presence of soaking time of 2 min, modified temperature of 65 degrees C, reaction time of 4 d, and lysozyme concentration of 0.5 g/L. PMID- 27699796 TI - Electrophysiological revelations of trial history effects in a color oddball search task. AB - In visual oddball search tasks, viewing a no-target scene (i.e., no-target selection trial) leads to the facilitation or delay of the search time for a target in a subsequent trial. Presumably, this selection failure leads to biasing attentional set and prioritizing stimulus features unseen in the no-target scene. We observed attention-related ERP components and tracked the course of attentional biasing as a function of trial history. Participants were instructed to identify color oddballs (i.e., targets) shown in varied trial sequences. The number of no-target scenes preceding a target scene was increased from zero to two to reinforce attentional biasing, and colors presented in two successive no target scenes were repeated or changed to systematically bias attention to specific colors. For the no-target scenes, the presentation of a second no-target scene resulted in an early selection of, and sustained attention to, the changed colors (mirrored in the frontal selection positivity, the anterior N2, and the P3b). For the target scenes, the N2pc indicated an earlier allocation of attention to the targets with unseen or remotely seen colors. Inhibitory control of attention, shown in the anterior N2, was greatest when the target scene was followed by repeated no-target scenes with repeated colors. Finally, search times and the P3b were influenced by both color previewing and its history. The current results demonstrate that attentional biasing can occur on a trial-by-trial basis and be influenced by both feature previewing and its history. PMID- 27699794 TI - Steady-state visual evoked potentials as a research tool in social affective neuroscience. AB - Like many other primates, humans place a high premium on social information transmission and processing. One important aspect of this information concerns the emotional state of other individuals, conveyed by distinct visual cues such as facial expressions, overt actions, or by cues extracted from the situational context. A rich body of theoretical and empirical work has demonstrated that these socioemotional cues are processed by the human visual system in a prioritized fashion, in the service of optimizing social behavior. Furthermore, socioemotional perception is highly dependent on situational contexts and previous experience. Here, we review current issues in this area of research and discuss the utility of the steady-state visual evoked potential (ssVEP) technique for addressing key empirical questions. Methodological advantages and caveats are discussed with particular regard to quantifying time-varying competition among multiple perceptual objects, trial-by-trial analysis of visual cortical activation, functional connectivity, and the control of low-level stimulus features. Studies on facial expression and emotional scene processing are summarized, with an emphasis on viewing faces and other social cues in emotional contexts, or when competing with each other. Further, because the ssVEP technique can be readily accommodated to studying the viewing of complex scenes with multiple elements, it enables researchers to advance theoretical models of socioemotional perception, based on complex, quasinaturalistic viewing situations. PMID- 27699793 TI - Genetic architecture of plant stress resistance: multi-trait genome-wide association mapping. AB - Plants are exposed to combinations of various biotic and abiotic stresses, but stress responses are usually investigated for single stresses only. Here, we investigated the genetic architecture underlying plant responses to 11 single stresses and several of their combinations by phenotyping 350 Arabidopsis thaliana accessions. A set of 214 000 single nucleotide polymorphisms (SNPs) was screened for marker-trait associations in genome-wide association (GWA) analyses using tailored multi-trait mixed models. Stress responses that share phytohormonal signaling pathways also share genetic architecture underlying these responses. After removing the effects of general robustness, for the 30 most significant SNPs, average quantitative trait locus (QTL) effect sizes were larger for dual stresses than for single stresses. Plants appear to deploy broad spectrum defensive mechanisms influencing multiple traits in response to combined stresses. Association analyses identified QTLs with contrasting and with similar responses to biotic vs abiotic stresses, and below-ground vs above-ground stresses. Our approach allowed for an unprecedented comprehensive genetic analysis of how plants deal with a wide spectrum of stress conditions.

AB - INTRODUCTION: Simple laboratory tests of upper motor neuron involvement in amyotrophic lateral sclerosis (ALS) are not available. Intermuscular coherence has been shown to distinguish patients with primary lateral sclerosis, a pure upper motor neuron disorder, from normal subjects, suggesting it could be useful for assessing ALS. We aimed to determine whether intermuscular coherence can distinguish ALS patients from normal subjects. METHODS: We measured biceps brachii and brachioradialis activity using surface electromyography while subjects held the elbow at flexion and the forearm in semipronation. Intermuscular coherence was calculated at between 20 and 40 Hz in 15 ALS patients and 15 normal subjects. RESULTS: On average, intermuscular coherence was 3.8-fold greater in normal subjects than in ALS patients (P < 0.01), and it distinguished ALS patients from normal subjects with a sensitivity of 87% and specificity of 87%. CONCLUSION: Intermuscular coherence measurement is a rapid, painless method that may detect upper motor neuron dysfunction in ALS. Muscle Nerve 55: 862-868, 2017. PMID- 27699798 TI - Reply.

In Phase 3, we conducted a treatment evaluation to increase compliance for each participant. We identified the antecedent and consequent variables responsible for noncompliance and developed an effective intervention for both participants. PMID- 27699801 TI - Self-Other Differences in Student Drinking Norms Research: The Role of Impression Management, Self-Deception, and Measurement Methodology. AB - BACKGROUND: Data-driven student drinking norms interventions are based on reported normative overestimation of the extent and approval of an average student's drinking. Self-reported differences between personal and perceived normative drinking behaviors and attitudes are taken at face value as evidence of actual levels of overestimation. This study investigates whether commonly used data collection methods and socially desirable responding (SDR) may inadvertently impede establishing "objective" drinking norms. METHODS: U.K. students (N = 421; 69% female; mean age 20.22 years [SD = 2.5]) were randomly assigned to 1 of 3 versions of a drinking norms questionnaire: The standard multi-target questionnaire assessed respondents' drinking attitudes and behaviors (frequency of consumption, heavy drinking, units on a typical occasion) as well as drinking attitudes and behaviors for an "average student." Two deconstructed versions of this questionnaire assessed identical behaviors and attitudes for participants themselves or an "average student." The Balanced Inventory of Desirable Responding was also administered. RESULTS: Students who answered questions about themselves and peers reported more extreme perceived drinking attitudes for the average student compared with those reporting solely on the "average student." Personal and perceived reports of drinking behaviors did not differ between multitarget and single-target versions of the questionnaire. Among those who completed the multitarget questionnaire, after controlling for demographics and weekly drinking, SDR was related positively with the magnitude of difference between students' own reported behaviors/attitudes and those perceived for the average student. CONCLUSIONS: Standard methodological practices and socially desirable responding may be sources of bias in peer norm overestimation research. PMID- 27699802 TI - Uromodulin gene variants and their association with renal function and blood pressure in cats: a pilot study. AB - OBJECTIVES: In humans, genome-wide association studies have identified variants in the uromodulin gene (UMOD) associated with blood pressure and renal function. This study aimed to evaluate the association of single nucleotide polymorphisms at the UMOD locus with renal function and blood pressure in cats. METHODS: We retrospectively identified cats aged 14 years that had participated in a geriatric monitoring program, and from which stored DNA samples were available, from a computerised database. We then measured the association of specific single nucleotide polymorphisms in the feline UMOD gene with renal function and systolic blood pressure as continuous variables and, also, the dichotomous outcome of azotaemic chronic kidney disease and systemic hypertension. RESULTS: Eight intronic single nucleotide polymorphisms, one 1372 base pairs upstream from UMOD and two exonic single nucleotide polymorphisms were evaluated in 227 cats with renal and blood pressure data. An analysis of 188 cats found four single nucleotide polymorphisms to be significantly associated (P<0.01) with systolic blood pressure although all were in linkage disequilibrium. No significant associations were identified between single nucleotide polymorphisms and renal function or chronic kidney disease. CLINICAL SIGNIFICANCE: Results of this pilot study suggest that genetic variation in UMOD might influence blood pressure in cats, similar to findings in humans. Validation of these results is required. PMID- 27699803 TI - Quorum Sensing Involved in the Spoilage Process of the Skin and Flesh of Vacuum Packaged Farmed Turbot (Scophthalmus maximus) Stored at 4 degrees C. AB - Fish skin has both positive and negative effects on the shelf-life of the fish. This study aimed to investigate the spoilage process of the skin and flesh of refrigerated farmed turbot (Scophthalmus maximus) with vacuum packaging. Microbial community changes were analyzed by combining culture-dependent and culture-independent methods. The results indicated that the shelf-life of vacuum packaged refrigerated turbot was 16 d; skin mucus was the interference factor of turbot quality. The culture-dependent analysis demonstrated that the total viable counts and the population of H2 S-producing bacteria, Pseudomonas spp., Enterobacteriaceae spp., and lactic acid bacteria in skin had a range of 0.45 to 1.40 log (CFU/g) higher than the microbial numbers in flesh after 16 d in storage. 16S high throughout sequencing results demonstrated that the compositions of spoilage microbes were similar in skin and flesh. Shewanella spp., followed by Carnobacterium spp., was the dominant spoilage organism at day 16. Quorum sensing (QS) signaling activity increased during the storage. Exogenous N-butanoyl-L-homoserinelactone(C4-HSL) and N-hexanoyl-Lhomoserine lactone (C6-HSL) significantly accelerated the spoilage process of refrigerated turbot, while the addition of 4, 5-Dihydroxypentane-2, 3-dione (DPD) prolonged the lag phase duration. Therefore, QS may be involved in the spoilage process of refrigerated turbot. PMID- 27699804 TI - Direct detection of mecA, blaSHV , blaCTX-M , blaTEM and blaOXA genes from positive blood culture bottles by multiplex-touchdown PCR assay. AB - : Methicillin-resistant staphylococci (MRS) and ESBL(Extended-Spectrum beta Lactamase)-producing bacteria are the most important resistant pathogens in sepsis. In this study, a new multiplex-touchdown PCR method (MT-PCR) was developed to detect rapidly and simultaneously the presence of mecA, blaSHV , blaCTX-M , blaTEM and blaOXA genes from positive blood culture bottles. The technique showed a sensitivity of 103 CFU ml-1 for mecA detection and of 102 CFU ml-1 for other genes, and 100% specificity in the detection of all genes. All genes were detected in the spiked blood culture bottles artificially contaminated with reference strains. Three methicillin-resistant S. aureus (MRSA), two methicillin-resistant S. epidermidis (MRSE) and 32 ESBL-producing bacteria, were isolated from the clinical blood culture specimens in 48 h by standard microbiological procedures. The corresponding genes were detected directly in the three MRSA, two MRSE and 29 ESBL-producing bacteria from the clinical blood culture specimens in 4 h by MT-PCR assay. None of the blaSHV , blaCTX-M , blaTEM and blaOXA genes were detected in three other bottles with ESBL-producing bacteria because of other ESBL genotypes in the pathogens. Likewise, all bottles proven negative by culture remained negative by PCR. The proposed method was rapid, sensitive and specific, and was able to directly detect the genes of MRS and ESBL-producing bacteria from the blood culture bottles. SIGNIFICANCE AND IMPACT OF THE STUDY: Many studies on the development of PCR for the detection of resistance genes have already been published, including multiplex PCR methods. However, cross-amplification reactions can be a major concern in multiplex PCR methods. In this study, we developed a highly sensitive and specific multiplex touchdown PCR assay for simultaneous detection of mecA, blaSHV , blaCTX-M , blaTEM and blaOXA genes from positive blood culture bottles, cross-amplification was absent and false-positive results were not obtained. PMID- 27699805 TI - A protein extraction method for low protein concentration solutions compatible with the proteomic analysis of rubber particles. AB - The extraction of high-purity proteins from the washing solution (WS) of rubber particles (also termed latex-producing organelles) from laticifer cells in rubber tree for proteomic analysis is challenging due to the low concentration of proteins in the WS. Recent studies have revealed that proteins in the WS might play crucial roles in natural rubber biosynthesis. To further examine the involvement of these proteins in natural rubber biosynthesis, we designed an efficiency method to extract high-purity WS proteins. We improved our current borax and phenol-based method by adding reextraction steps with phenol (REP) to improve the yield from low protein concentration samples. With this new method, we extracted WS proteins that were suitable for proteomics. Indeed, compared to the original borax and phenol-based method, the REP method improved both the quality and quantity of isolated proteins. By repeatedly extracting from low protein concentration solutions using the same small amount of phenol, the REP method yielded enough protein of sufficiently high-quality from starting samples containing less than 0.02 mg of proteins per milliliter. This method was successfully applied to extract the rubber particle proteins from the WS of natural rubber latex samples. The REP-extracted WS proteins were resolved by 2DE, and 28 proteins were positively identified by MS. This method has the potential to become widely used for the extraction of proteins from low protein concentration solutions for proteomic analysis.

The mechanism of sexual fate decision in germ cells has been a long standing issue in biology. A recent analysis identified foxl3 as a gene that determines the sexual fate decision of germ cells in the teleost fish, medaka. foxl3/Foxl3 acts in female germline stem cells to repress commitment into male fate (spermatogenesis), indicating that the presence of mitotic germ cells in the female is critical for continuous sexual fate decision of germ cells in medaka gonads. Interestingly, foxl3 is found in most vertebrate genomes except for mammals. This provides the interesting possibility that the sexual fate of germ cells in mammals is determined in a different way compared to foxl3-possessing vertebrates. Considering the fact that germline stem cells are the cells where foxl3 begins to express and sexual fate decision initiates and mammalian ovary does not have typical germline stem cells, the mechanism in mammals may have been co-evolved with germline stem cell loss in mammalian ovary.

AB - Farmed Atlantic salmon (Salmo salar) is a globally important production species, including in Australia where breeding and selection has been in progress since the 1960s. The recent development of SNP genotyping platforms means genome-wide association and genomic prediction can now be implemented to speed genetic gain. As a precursor, this study collected genotypes at 218 132 SNPs in 777 fish from a Tasmanian breeding population to assess levels of genetic diversity, the strength of linkage disequilibrium (LD) and imputation accuracy. Genetic diversity in Tasmanian Atlantic salmon was lower than observed within European populations when compared using four diversity metrics. The distribution of allele frequencies also showed a clear difference, with the Tasmanian animals carrying an excess of low minor allele frequency variants. The strength of observed LD was high at short distances (<25 kb) and remained above background for marker pairs separated by large chromosomal distances (hundreds of kb), in sharp contrast to the European Atlantic salmon tested. Genotypes were used to evaluate the accuracy of imputation from low density (0.5 to 5 K) up to increased density SNP sets (78 K). This revealed high imputation accuracies (0.89-0.97), suggesting that the use of low density SNP sets will be a successful approach for genomic prediction in this population. The long-range LD, comparatively low genetic diversity and high imputation accuracy in Tasmanian salmon is consistent with known aspects of their population history, which involved a small founding population and an absence of subsequent introgression. The findings of this study represent an important first step towards the design of methods to apply genomics in this economically important population. PMID- 27699808 TI - A review of mortality associated with elongate mineral particle (EMP) exposure in occupational epidemiology studies of gold, talc, and taconite mining. AB - BACKGROUND: Mining of gold, taconite, and talc may involve exposure to elongate mineral particles (EMP). The involved EMPs are typically non-asbestiform, include dimensions that regulatory definitions exclude, and have been less studied. METHODS: A review of the literature was undertaken for this exposure and occupational epidemiological studies that occur in gold, talc, and taconite mining. RESULTS: Quantitative EMP exposure information in these industries is incomplete. However, there are consistent findings of pneumoconiosis in each of these types of mining. A recent case-control study suggests a possible association between this exposure and mesothelioma. Lung cancer is inconsistently reported in these industries and is an unlikely outcome of non-asbestiform EMP exposure. There is evidence of cardiovascular mortality excess across all of these types of mining. CONCLUSIONS: Non-malignant respiratory disease and cardiovascular mortality have been consistently increased in these industries. Further investigation, including additional insights for the role of non asbestiform EMP, is warranted. Am. J. Ind. Med. 59:1047-1060, 2016. (c) 2016 Wiley Periodicals, Inc. PMID- 27699809 TI - Complexes of a Zn-metalloenzyme binding site with hydroxamate-containing ligands. A case for detailed benchmarkings of polarizable molecular mechanics/dynamics potentials when the experimental binding structure is unknown. AB - Zn-metalloproteins are a major class of targets for drug design. They constitute a demanding testing ground for polarizable molecular mechanics/dynamics aimed at extending the realm of quantum chemistry (QC) to very long-duration molecular dynamics (MD). The reliability of such procedures needs to be demonstrated upon comparing the relative stabilities of competing candidate complexes of inhibitors with the recognition site stabilized in the course of MD. This could be necessary when no information is available regarding the experimental structure of the inhibitor-protein complex. Thus, this study bears on the phosphomannose isomerase (PMI) enzyme, considered as a potential therapeutic target for the treatment of several bacterial and parasitic diseases. We consider its complexes with 5 phospho-d-arabinonohydroxamate and three analog ligands differing by the number and location of their hydroxyl groups. We evaluate the energy accuracy expectable from a polarizable molecular mechanics procedure, SIBFA. This is done by comparisons with ab initio quantum-chemistry (QC) calculations in the following cases: (a) the complexes of the four ligands in three distinct structures extracted from the entire PMI-ligand energy-minimized structures, and totaling up to 264 atoms; (b) the solvation energies of several energy-minimized complexes of each ligand with a shell of 64 water molecules; (c) the conformational energy differences of each ligand in different conformations characterized in the course of energy-minimizations; and (d) the continuum solvation energies of the ligands in different conformations. The agreements with the QC results appear convincing. On these bases, we discuss the prospects of applying the procedure to ligand macromolecule recognition problems. (c) 2016 Wiley Periodicals, Inc. PMID- 27699810 TI - Potential of 13 linked autosomal short tandem repeat loci in pairwise kinship analysis. AB - In this study, a panel of 13 STR loci locate on chromosome 3, 4, and 17 (D3S2402, D3S2452, D3S1766, D3S4554, D3S2388, D3S3051, D3S3053, D4S2404, D4S2364, AC001348A, AC001348B, D17S975, and D17S1294) were assessed for pairwise kinship analysis. Map distances between these STR loci ranged from 0.07 cM to 97.03 cM. The population genetic study of Chinese Han population showed that linkage disequilibrium exists in two clusters of closely linked markers (D4S2404-D4S2364 and D17S975-D17S1294), in which the recombination fractions were 0.0026 and 0.0001, respectively. The recombination fractions derived from the Rutgers Map for the closely linked markers (genetic distance < 0.5 cM) were significant underestimates in comparison to those of direct observation of STR transmissions in families. When effect of linkage on pairwise kinship testing was evaluated by comparing likelihood ratio (LR) values taking linkage into account, overall LR values increased. But extremely low LRs were also observed. Finally, the power of the 13 STR loci to discriminate relationship among full-sibs, half-sibs, grandparent-grandchild, uncle-niece, and unrelated pairs was assessed with a category fraction. The results showed that about 72.64% of full-sib pairs and about 82.84% of unrelated pairs could be classified correctly. But the category fractions of second-degree relationships drastically reduced to 7.34-35.48%. If only pairs of grandparent-grandchild, half-sibs, and uncle-niece were distinguished, the category fraction was 0.5512, 0.1147, and 0.4362, respectively. Our study results demonstrated that linked STRs were helpful to differentiate the most frequent relationships in pairwise kinship analysis. PMID- 27699811 TI - Task distribution, work environment, and perceived health discomforts among Indian ceramic workers. AB - BACKGROUND: The study examined the work environment of Indian ceramics workers and assessed associations between work hazards, work category, and self-reported symptoms. METHODS: The multi-method ergonomic review technique (MMERT) checkpoints was used for work analysis and prevalence of self-reported symptoms among 329 male workers. RESULTS: Ambient temperature and relative humidity in ceramic industries were 39.9 degrees C and 17.4% respectively. Musculoskeletal discomfort was observed as a primary complaint; especially lower extremity pain (45%). Load handlers and machine operators had the highest levels of work hazards, including high skill requirement, strenuous work posture, poor commitment by the organization. Poor job autonomy, task clarity, hot workplace, inappropriate workplace design, inadequate auxiliary support, and mental overload were significantly associated with self-reported symptoms (P < 0.001). CONCLUSION: Work categories are associated with work hazards and may lead to various health symptoms among ceramic workers. Control of workplace hazards may lower rates of symptoms and thus may lead to improved health, productivity, and well-being. Am. J. Ind. Med. 59:1145-1155, 2016. (c) 2016 Wiley Periodicals, Inc. PMID- 27699812 TI - Lactate release from astrocytes to neurons contributes to cocaine memory formation. AB - The identification of neural substrates underlying the long lasting debilitating impact of drug cues is critical for developing novel therapeutic tools. Metabolic coupling has long been considered a key mechanism through which astrocytes and neurons actively interact in response of neuronal activity, but recent findings suggested that disrupting metabolic coupling may represent an innovative approach to prevent memory formation, in particular drug-related memories. Here, we review converging evidence illustrating how memory and addiction share neural circuitry and molecular mechanisms implicating lactate-mediated metabolic coupling between astrocytes and neurons. With several aspects of addiction depending on mnemonic processes elicited by drug experience, disrupting lactate transport involved in the formation of a pathological learning, linking the incentive, and motivational effects of drugs with drug-conditioned stimuli represent a promising approach to encourage abstinence. PMID- 27699813 TI - FOXO3a Expression Regulated by ERK Signaling is Inversely Correlated With Y-Box Binding Protein-1 Expression in Prostate Cancer. AB - BACKGROUND: FOXO3a is a member of the forkhead O transcription factors. FOXO3a induces the factors that contribute to cell cycle arrest and is considered a tumor suppressor in several malignant tumors. Y-box binding protein-1 (YB-1) is a multifunctional protein whose high expression is correlated with poor prognoses in various malignant tumors. In the current study, we investigated the relationship between FOXO3a and YB-1 to validate their functional roles in prostate cancer. METHODS: Western blotting and cytotoxicity assays were conducted in prostate cancer cells, LNCaP, and 22Rv1 cells. We also evaluated the protein expressions of FOXO3a and YB-1 in human prostate cancer tissues, using radical prostatectomy specimens. Then, we investigated the correlations between protein expressions and clinicopathologic parameters. RESULTS: We found that both FOXO3a and YB-1 proteins were phosphorylated by ERK signaling, resulting in FOXO3a inactivation and YB-1 activation in LNCaP and 22Rv1 cells. Inversely, inhibition of MEK or treatment with metformin activated FOXO3a through inactivation of ERK signaling and suppressed the viability of LNCaP and 22Rv1 cells in a dose dependent manner. In immunohistochemical analysis, FOXO3a nuclear expression was inversely correlated with YB-1 nuclear expression (P < 0.0001). Furthermore, high FOXO3a nuclear expression was inversely correlated with a higher Gleason grade (P < 0.0001) and higher preoperative PSA (P = 0.0437). CONCLUSIONS: These results showed that in prostate cancer, FOXO3a, and YB-1 play inverse reciprocal roles as a tumor-suppressor gene and oncogene, respectively, through their master regulator ERK.

AB - There is a public perception that the white-tailed deer Odocoileus virginianus (Artiodactyla: Cervidae) is the main reservoir supporting the maintenance and spread of the causative agent of Lyme disease, Borrelia burgdorferi. This study examines the pathogen prevalence rate of Borrelia in adult Ixodes scapularis (Ixodida: Ixodidae), the black-legged tick, collected from white-tailed deer and compares it with pathogen prevalence rates in adult ticks gathered by dragging vegetation in two contiguous counties west of the Hudson Valley in upstate New York. In both Broome and Chenango Counties, attached and unattached ticks harvested from white-tailed deer had significantly lower prevalences of B. burgdorferi than those collected from vegetation. No attached ticks on deer (n = 148) in either county, and only 2.4 and 7.3% of unattached ticks (n = 389) in Broome and Chenango Counties, respectively, were harbouring the pathogen. This contrasts with the finding that 40.8% of ticks in Broome County and 46.8% of ticks in Chenango County collected from vegetation harboured the pathogen. These data suggest that a mechanism in white-tailed deer may aid in clearing the pathogen from attached deer ticks, although white-tailed deer do contribute to the spatial distribution of deer tick populations and also serve as deadend host breeding sites for ticks. PMID- 27699815 TI - Impact of the implementation of vasoactive drug protocols on safety and efficacy in the treatment of critically ill patients. AB - WHAT IS KNOWN AND OBJECTIVE: The correct management of high-alert medications is a priority issue in expert recommendations for improving the clinical safety of patients. Objectives were to assess the impact of the implementation of vasoactive drug (VAD) protocols on safety and efficacy in the treatment of critically ill patients. METHODS: A prospective before-and-after study on the implementation of different VAD protocols, comparing medication errors (MEs) rates, mean intensive care unit (ICU) stay, mean blood pressure (MAP), heart rate (HR) and oxygen saturation. RESULTS AND DISCUSSION: The study included 432 patients. There was a statistically significant decrease in prescribing errors (55.9%), validation errors (68.1%) and medication administration records (MAR) errors (78.8%). No differences were found between the two phases in ICU stay, MAP, HR and oxygen saturation. WHAT IS NEW AND CONCLUSION: Implementation of protocols decreases variability in clinical practice, reduces the incidence of MEs and maintains the effectiveness of VAD therapy in critically ill patients. PMID- 27699816 TI - Disparities in precarious workers' health care access in South Korea. AB - BACKGROUND: This study explored whether precarious workers have difficulties in health care access as compared with non-precarious workers. METHODS: The 2008 Korean Community Health Survey data were used for this study. Information was obtained on 51,322 participants (40,514 non-precarious workers and 10,808 precarious workers). Precarious workers were defined as part-time or contingent workers. RESULTS: Precarious workers had significantly higher risk of limited access to hospitals (OR = 1.14; 95% CI: 1.06-1.22) and dentists (OR = 1.28; 95% CI: 1.21-1.36) than non-precarious workers; disparities in doctor contacts among precarious workers were mostly linked to not having enough money. The risk of not receiving preventive care-medical checkups (OR = 0.52; 95% CI: 0.49-0.55) or cancer screenings (OR = 0.82; 95% CI: 0.77-0.86)-was also significantly elevated among precarious workers. CONCLUSION: We found that precarious workers had more difficulty accessing health care or receiving health checkups or cancer screenings than their non-precarious counterparts. Am. J. Ind.

AB - Discrimination slope, defined as the slope of a linear regression of predicted probabilities of event derived from a prognostic model on the binary event status, has recently gained popularity as a measure of model performance. It is as a building block for the integrated discrimination improvement that equals the difference in discrimination slopes between the two models being compared. Several authors have pointed out that it does not make sense to apply the integrated discrimination improvement and discrimination slope when working with mis-calibrated models, whereas others have raised concerns about the ability of improving discrimination slope without adding new information. In this paper, we show that under certain assumptions the discrimination slope is asymptotically related to two other R-squared measures, one of which is a rescaled version of the Brier score, known to be proper. Furthermore, we illustrate how a simple recalibration makes the slope equal to the rescaled Brier R-squared metric. We also show that the discrimination slope can be interpreted as a measure of reduction in expected regret for the Gini-Brier regret function. Using theoretical and practical examples, we illustrate how all of these metrics are affected by different levels of model mis-calibration. In particular, we demonstrate that simple recalibration ascertaining calibration in-the-large and calibration slope equal to 1 are not sufficient to correct for some forms of mis calibration. We conclude that R-squared metrics, including the discrimination slope, offer an attractive choice for quantifying model performance as long as one accounts for their sensitivity to model calibration.

PMID- 27699817 TI - Revisiting cancer 15 years later: Exploring mortality among agricultural and non agricultural workers in the Serrana Region of Rio de Janeiro. AB - : Background Agricultural production has expanded dramatically throughout Brazil. Previous research in the Serrana Region found that from 1979 to 1998, agricultural workers experienced high mortality rates from certain cancers compared to non-agricultural workers [Meyer et al. (2003): Environ Res 93:264 271]. METHODS: New data were obtained for 1999-2013 and Mortality Odds Ratios (MORs) were utilized to compare cancer and other mortality between male agricultural workers in the Serrana Region and non-agricultural workers in the Serrana Region, Rio de Janeiro, and Porto Alegre, and to compare mortality odds to previous decades. RESULTS: Respectively, compared to aforementioned reference groups, agricultural workers experienced highest MORs for stomach (1.55 [95%CI: 1.13-2.12], 2.30 [95%CI: 1.72-3.08], 2.28 [95%CI: 1.69-3.08]) and esophageal cancers (95%CI: 1.93 [1.38-2.7], 1.93 [95%CI: 1.38-2.71], 3.12 [95%CI: 2.30 4.24]), greater than reported in previous decades. Agricultural workers experienced higher mortality for external-causes, respiratory, and cardiovascular problems compared to urban reference-groups. CONCLUSION: Agricultural workers may be at increasing risk for cancer and other mortality. Efforts are needed to investigate distinct risk-factors among this group. Am. J. Ind. Med. 60:77-86, 2017.

AB - BACKGROUND: This study sought to identify impacts of compensation system characteristics on doctors in Quebec and Ontario. METHODS: (i) Legal analysis; (ii) Qualitative methods applied to documentation and individual and group interviews with doctors (34) and other system participants (31); and (iii) Inter jurisdictional transdisciplinary analysis involving cross-disciplinary comparative and integrative analysis of policy contexts, qualitative data, and the relationship between the two. RESULTS: In both jurisdictions the compensation board controlled decisions on work-relatedness and doctors perceived the bureaucratic process negatively. Gatekeeping roles differed between jurisdictions both in initial adjudication and in dispute processes. Quebec legislation gives greater weight to the opinion of the treating physician. These differences affected doctors' experiences. CONCLUSIONS: Policy-makers should contextualize the sources of the "evidence" they rely on from intervention research because findings may reflect a system rather than an intervention effect. Researchers should consider policy contexts to both adequately design a study and interpret their results. Am. J. Ind. Med. 59:1070-1086, 2016. (c) 2016 Wiley Periodicals, Inc. PMID- 27699819 TI - Prostate Specific Antigen-Growth Curve Model to Predict High-Risk Prostate Cancer. AB - PURPOSE: To investigate if a prostate specific antigen (PSA)-derived growth curve can predict the occurrence of high-risk prostate cancer (PrCA). METHODS: Data from 38,340 men randomized to the PrCA screening arm in the prostate, lung, colorectal, and ovarian cancer screening trial (PLCO) were used to develop a PSA growth curve model to estimate PSA rate of change. The model was then used to predict high-risk PrCA in clinical data available from 680,390 veterans seeking routine care. The PSA growth curve was modeled using non-linear mixed regression and the PSA rate was estimated by taking the 1st derivative of the growth curve equation at 1 year prior to diagnosis/exit. RESULTS: In the PLCO, PrCA incidence was 8.1%; ~19% of whom had high-risk PrCA. Overall, a PSA rate threshold of 0.37 ng/ml/year had the best combination of sensitivity (97.2%) and specificity (97.3%) for detecting high-risk PrCA. In the VA data; 7,347 men were diagnosed with PrCA; of these 4,315 (58.7%) were diagnosed with high-risk PrCA. The PLCO optimal threshold of 0.37 ng/ml/year produced sensitivity = 95.5% and specificity = 85.2%. An optimal threshold of 0.99 ng/ml/year in AA produced sensitivity = 89.1% and specificity = 80.0%. PSA rate was a better predictor than the single last PSA value. CONCLUSIONS: PSA growth curves predicted high-risk PrCA in the PLCO data. Fitting the same algorithm in the VA data produced lower specificity. Although encouraging, this finding underlines the need for further research to prospectively test the algorithm, especially for African-American men, the population group at highest risk of aggressive PrCA.

PMID- 27699821 TI - Dissecting the effects of antibiotics on horizontal gene transfer: Analysis suggests a critical role of selection dynamics. AB - Horizontal gene transfer (HGT) is a major mechanism responsible for the spread of antibiotic resistance. Conversely, it is often assumed that antibiotics promote HGT. Careful dissection of the literature, however, suggests a lack of conclusive evidence supporting this notion in general. This is largely due to the lack of well-defined quantitative experiments to address this question in an unambiguous manner. In this review, we discuss the extent to which HGT is responsible for the spread of antibiotic resistance and examine what is known about the effect of antibiotics on the HGT dynamics. We focus on conjugation, which is the dominant mode of HGT responsible for spreading antibiotic resistance on the global scale. Our analysis reveals a need to design experiments to quantify HGT in such a way to facilitate rigorous data interpretation. Such measurements are critical for developing novel strategies to combat resistance spread through HGT. PMID- 27699823 TI - Chronic Pelvic Pain Development and Prostate Inflammation in Strains of Mice With Different Susceptibility to Experimental Autoimmune Prostatitis. AB - BACKGROUND: Experimental autoimmune prostatitis (EAP) is an autoimmune inflammatory disease of the prostate characterized by peripheral prostate specific autoimmune responses associated with prostate inflammation. EAP is induced in rodents upon immunization with prostate antigens (PAg) plus adjuvants and shares important clinical and immunological features with the human disease chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: EAP was induced in young NOD, C57BL/6, and BALB/c male mice by immunization with PAg plus complete Freunds adjuvant. Tactile allodynia was assessed using Von Frey fibers as a measure of pelvic pain at baseline and at different time points after immunization. Using conventional histology, immunohistochemistry, FACS analysis, and protein arrays, an interstrain comparative study of prostate cell infiltration and inflammation was performed. RESULTS: Chronic pelvic pain development was similar between immunized NOD and C57BL/6 mice, although the severity of leukocyte infiltration was greater in the first case. Coversely, minimal prostate cell infiltration was observed in immunized BALB/c mice, who showed no pelvic pain development. Increased numbers of mast cells, mostly degranulated, were detected in prostate samples from NOD and C57BL/6 mice, while lower total counts and resting were observed in BALB/c mice. Prostate tissue from NOD mice revealed markedly increased expression levels of inflammatory cytokines, chemokines, adhesion molecules, vascular endothelial growth factor, and metalloproteinases. Similar results, but to a lesser extent, were observed when analyzing prostate tissue from C57BL/6 mice. On the contrary, the expression of the above mediators was very low in prostate tissue from immunized BALB/c mice, showing significantly slight increments only for CXCL1 and IL4. CONCLUSIONS: Our results provide new evidence indicating that NOD, C57BL/6, and BALB/c mice develop different degrees of chronic pelvic pain, type, and amount of prostate cell infiltration and secretion of inflammatory mediators. Our results corroborate and support the notion that mice with different genetic background have different susceptibility to EAP induction. Prostate 77:94-104, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27699822 TI - Analysis of isoquinoline alkaloids using chitosan-assisted liquid-solid extraction followed by microemulsion liquid chromatography employing a sub-2 micron particle stationary phase. AB - A simple, efficient, and green chitosan-assisted liquid-solid extraction method was developed for the sample preparation of isoquinoline derivative alkaloids followed by microemulsion LC. The optimized mobile phase consisted of 0.8% w/v of ethyl acetate, 1.0% w/v of SDS, 8.0% w/v of n-butanol, 0.1% v/v acetic acid, and 10% v/v ACN. Compared to pharmacopoeia method and organic solvent extraction, this new approach avoided the use of volatile organic solvents, replacing them with relatively small amounts of chitosan. Under the optimum conditions, good linearity (r2 > 0.9980) for all calibration curves and low detection limits between 0.05 and 0.10 MUg/mL were achieved. The presented procedure was successfully applied to determine alkaloids in Rhizoma coptidis with satisfactory recoveries (81.3-106.4%).

AB - This paper comprises a continuation of computer simulation studies dealing with carrier ampholyte based CIEF in presence of narrow pH gradients. With this technique, amphoteric sample components with pI values outside the pH gradient are migrating isotachophoretically toward the cathode or anode whereas components with pI values within the gradient become focused. In order to understand the processes occurring in presence of the electric field, the behavior of both carrier ampholytes and amphoteric sample components is investigated by computer modeling. Characteristics of two pH unit gradients with end components having pI values at or around 7.00 and conditions that lead to the formation of a water zone at neutrality were investigated. Data obtained reveal that a zone of water is formed in focusing with carrier ampholytes when the applied pH range does not cover the neutral region, ends at pH 7.00 or begins at pH 7.00. The presence of additional amphoteric components that cover the neutrality region prevent water zone formation under current flow. This situation is met in experiments with narrow pH gradients that end or begin around neutrality. Simulation data reveal that no water zone evolves when atmospheric carbon dioxide dissolved in the catholyte causes the migration of carbonic acid (in the form of carbonate and/or hydrogen carbonate ions) from the catholyte through the focusing structure. An electrolyte change in the electrode solution does not have an impact on the focusing part but does change the isotachophoretic pattern migrating behind the leading ion. PMID- 27699825 TI - Elevated C-Peptides, Abdominal Obesity, and Abnormal Adipokine Profile are Associated With Higher Gleason Scores in Prostate Cancer. AB - BACKGROUND: Prostate cancer development is associated with numerous lifestyle factors (i.e., physical activity, nutrition intake) and metabolic perturbations. These factors have been studied independently; here, we used an integrative approach to characterize these lifestyle and metabolic parameters in men undergoing diagnostic prostate biopsies. METHODS: We prospectively evaluated 51 consecutive men for body composition, metabolic factors including glucose- and lipid-related measures, as well as lifestyle factors prior to prostate biopsy. Evaluations were performed in a blinded manner and were subsequently related to biopsy outcomes for: (i) presence or absence of cancer; and (ii) where cancer was present, Gleason score. RESULTS: Serum C-peptide concentrations were significantly greater in participants with Gleason scores >=4 + 3 (2.8 +/- 1.1 ng/ml) compared to those with Gleason 3 + 3 (1.4 +/- 0.6 ng/ml) or Gleason 3 + 4 (1.3 +/- 0.8 ng/ml, P = 0.002), suggesting greater insulin secretion despite lack of differences in fasting glucose concentrations. Central adiposity, measured by waist circumference, was significantly greater in participants with Gleason >=4 + 3 (110.1 +/- 7.4 cm) compared to those with Gleason 3 + 4 (102.0 +/- 9.5 cm, P = 0.028). Men with Gleason >=4 + 3 also had significantly greater leptin concentrations than those with lower Gleason scores (Gleason >=4 + 3: 15.6 +/- 3.3 ng/ml vs. Gleason 3 + 4: 8.1 +/- 8.1 ng/ml, P < 0.05) and leptin:adiponectin ratio (Gleason >=4 + 3: 9.7 +/- 6.1 AU, Gleason 3 + 4: 2.9 +/- 3.2, Gleason 3 + 3: 2.4 +/- 2.1 AU, P = 0.013). CONCLUSIONS: We profiled a cluster of obesity related metabolic perturbations (C-peptide, central adiposity, leptin, and leptin:adiponectin ratios) which may associate with more aggressive prostate cancer histology.

AB - The oxidative demethylation procedure for a new epoxy lignan isolated from Piper nigrum was applied to the synthesis of 3'-methoxy-3",4"-(methylenedioxy)-2,5 epoxylignan-4'-ol-6'-one. This compound inhibited the mRNA expression of the protein patched homolog (Ptch) in human pancreatic cancer cells (PANC1) and therefore might be valuable as a probe for tumor-related disease. The pharmacokinetic profile of 3'-methoxy-3",4"-(methylenedioxy)-2,5-epoxylignan-4' ol-6'-one was rapidly determined using ultra-fast liquid chromatography. The compound was rapidly absorbed in blood. PMID- 27699827 TI - Rotator cuff tear state modulates self-renewal and differentiation capacity of human skeletal muscle progenitor cells. AB - Full thickness rotator cuff tendon (RCT) tears have long-term effects on RC muscle atrophy and fatty infiltration, with lasting damage even after surgical tendon repair. Skeletal muscle progenitor cells (SMPs) are critical for muscle repair in response to injury, but the inability of RC muscles to recover from chronic RCT tear indicates possible deficits in repair mechanisms. Here we investigated if muscle injury state was a crucial factor during human SMP expansion and differentiation ex vivo. SMPs were isolated from muscles in patients with no, partial-thickness (PT), or full-thickness (FT) RCT tears. Despite using growth factors, physiological niche stiffness, and muscle-mimetic extracellular matrix (ECM) proteins, we found that SMPs isolated from human RC muscle with RCT tears proliferated slower but fused into myosin heavy chain (MHC) positive myotubes at higher rates than SMPs from untorn RCTs. Proteomic analysis of RC muscle tissue revealed shifts in muscle composition with pathology, as muscle from massive RCT tears had increased ECM deposition compared with no tear RC muscle. Together these data imply that the remodeled niche in a torn RCT primes SMPs not for expansion but for differentiation, thus limiting longer-term self-renewal necessary for regeneration after surgical repair.

Fish embryo acute toxicity tests are 1 tool that has been shown to be highly predictive of standard, more resource-intensive, juvenile fish acute toxicity tests. However, there is also evidence that fish embryos are less sensitive than juvenile fish for certain types of chemicals, including neurotoxicants. The utility of fish embryos for pesticide hazard assessment was investigated by comparing published zebrafish embryo toxicity data from pesticides with median lethal concentration 50% (LC50) data for juveniles of 3 commonly tested fish species: rainbow trout, bluegill sunfish, and sheepshead minnow. A poor, albeit significant, relationship (r2 = 0.28; p < 0.05) was found between zebrafish embryo and juvenile fish toxicity when pesticides were considered as a single group, but a much better relationship (r2 = 0.64; p < 0.05) when pesticide mode of action was factored into an analysis of covariance. This discrepancy is partly explained by the large number of neurotoxic pesticides in the dataset, supporting previous findings that commonly used fish embryo toxicity test endpoints are particularly insensitive to neurotoxicants. These results indicate that it is still premature to replace juvenile fish toxicity tests with embryo-based tests such as the Organisation for Economic Co-operation and Development Fish Embryo Acute Toxicity Test for routine pesticide hazard assessment, although embryo testing could be used with other screening tools for testing prioritization.

AB - Specific gene mutations leading to dysregulation of innate immune response produce the expanding spectrum of monogenic autoinflammatory diseases (AIDs). They are characterized by seemingly unprovoked, recurrent episodes of systemic inflammation in which a myriad of manifestations usually affect skin. Novel genetic technologies have led to the discovery of new AIDs and phenotypes that were not previously clinically described. Consequently the number of AIDs is continuously growing and their recognition and the disclosure of their pathophysiology will prompt early diagnosis and targeted treatment of affected patients. The objective of the present work is to review those newly described AIDs with prominent dermatologic manifestations that may constitute a major criterion for their diagnosis. PMID- 27699828 TI - High-Content Screening Identifies Src Family Kinases as Potential Regulators of AR-V7 Expression and Androgen-Independent Cell Growth. AB - BACKGROUND: AR-V7 is an androgen receptor (AR) splice variant that lacks the ligand-binding domain and is isolated from prostate cancer cell lines. Increased expression of AR-V7 is associated with the transition from hormone-sensitive prostate cancer to more advanced castration-resistant prostate cancer (CRPC). Due to the loss of the ligand-binding domain, AR-V7 is not responsive to traditional AR-targeted therapies, and the mechanisms that regulate AR-V7 are still incompletely understood. Therefore, we aimed to explore existing classes of small molecules that may regulate AR-V7 expression and intracellular localization and their potential therapeutic role in CRPC. METHODS: We used AR high-content analysis (AR-HCA) to characterize the effects of a focused library of well characterized clinical compounds on AR-V7 expression at the single-cell level in PC3 prostate cancer cells stably expressing green fluorescent protein (GFP)-AR-V7 (GFP-AR-V7:PC3). In parallel, an orthogonal AR-HCA screen of a small interfering (si)RNA library targeting 635 protein kinases was performed in GFP-AR-V7:PC3. The effect of the Src-Abl inhibitor PD 180970 was further characterized using cell proliferation assays, quantitative PCR, and western blot analysis in multiple hormone-sensitive and CRPC cell lines. RESULTS: Compounds that tended to target Akt, Abl, and Src family kinases (SFKs) decreased overall AR-V7 expression, nuclear translocation, absolute nuclear level, and/or altered nuclear distribution. We identified 20 protein kinases that, when knocked down, either decreased nuclear GFP-AR-V7 levels or altered AR-V7 nuclear distribution, a set that included the SFKs Src and Fyn. The Src-Abl dual kinase inhibitor PD180970 decreased expression of AR-V7 by greater than 46% and decreased ligand independent transcription of AR target genes in the 22RV1 human prostate carcinoma cell line. Further, PD180970 inhibited androgen-independent cell proliferation in endogenous-AR-V7-expressing prostate cancer cell lines and also overcame bicalutamide resistance observed in the 22RV1 cell line. CONCLUSIONS: SFKs, especially Src and Fyn, may be important upstream regulators of AR-V7 expression and represent promising targets in a subset of CRPCs expressing high levels of AR-V7.

AB - Freshwater mussels, one of the most imperiled groups of animals in the world, are generally underrepresented in toxicity databases used for the development of ambient water quality criteria and other environmental guidance values. Acute 96 h toxicity tests were conducted to evaluate the sensitivity of 5 species of juvenile mussels from 2 families and 4 tribes to 10 chemicals (ammonia, metals, major ions, and organic compounds) and to screen 10 additional chemicals (mainly organic compounds) with a commonly tested mussel species, fatmucket (Lampsilis siliquoidea). In the multi-species study, median effect concentrations (EC50s) among the 5 species differed by a factor of <=2 for chloride, potassium, sulfate, and zinc; a factor of <=5 for ammonia, chromium, copper, and nickel; and factors of 6 and 12 for metolachlor and alachlor, respectively, indicating that mussels representing different families or tribes had similar sensitivity to most of the tested chemicals, regardless of modes of action. There was a strong linear relationship between EC50s for fatmucket and the other 4 mussel species across the 10 chemicals (r2 = 0.97, slope close to 1.0), indicating that fatmucket was similar to other mussel species; thus, this commonly tested species can be a good surrogate for protecting other mussels in acute exposures. The sensitivity of juvenile fatmucket among different populations or cultured from larvae of wild adults and captive-cultured adults was also similar in acute exposures to copper or chloride, indicating captive-cultured adult mussels can reliably be used to reproduce juveniles for toxicity testing. In compiled databases for all freshwater species, 1 or more mussel species were among the 4 most sensitive species for alachlor, ammonia, chloride, potassium, sulfate, copper, nickel, and zinc; therefore, the development of water quality criteria and other environmental guidance values for these chemicals should reflect the sensitivity of mussels. In contrast, the EC50s of fatmucket tested in the single-species study were in the high percentiles (>75th) of species sensitivity distributions for 6 of 7 organic chemicals, indicating mussels might be relatively insensitive to organic chemicals in acute exposures.

PMID- 27699832 TI - Value of delayed gadolinium-enhanced magnetic resonance imaging of cartilage for the pre-operative assessment of cervical intervertebral discs. AB - The study was performed to preoperatively assess the cartilage integrity of cervical intervertebral discs (IVDs) using Delayed Gadolinium-Enhanced Magnetic Resonance Imaging of Cartilage (dGEMRIC). Therefore, 53 cervical intervertebral discs of nine preoperative patients with neck and shoulder/arm pain scheduled for discectomy (five females, four males; mean age: 47.1 +/- 8.4 years; range: 36-58 years) were included for biochemical analysis in this retrospective study. The patients underwent 3T magnetic resonance imaging (MRI) including biochemical imaging with dGEMRIC and morphological, sagittal T2 weighted (T2w) imaging. Cervical IVDs were rated using an MRI based grading system for cervical IVDs on T2w images. Region-of-interest measurements were performed in the nucleus pulposus (NP) and annulus fibrosus (AF) and a dGEMRIC index was calculated. Our results demonstrated that IVDs scheduled for discectomy showed significantly lower dGEMRIC index compared to IVDs that did not require surgical intervention in NP and AF (NP: 898.4 +/- 191.9 ms vs. 1,150.3 +/- 320.7 ms, p = 0.008; AF: 738.7 +/- 183.8 ms vs. 984.6 +/- 178.9 ms, p = 0.008). For Miyazaki score 3, the dGEMRIC indices were significantly lower in IVDs scheduled for surgery compared to non-operated discs for NP (p = 0.043) and AF (p = 0.018). In conclusion we could demonstrate that biochemical imaging with dGEMRIC is feasible in cervical IVDs. Significantly lower dGEMRIC index suggested GAG depletion in degenerated cervical IVD, scheduled for discectomy. (c) 2016 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

PMID- 27699833 TI - Effects of cell type and configuration on anabolic and catabolic activity in 3D co-culture of mesenchymal stem cells and nucleus pulposus cells. AB - Tissue engineering constructs to treat intervertebral disc degeneration must adapt to the hypoxic and inflammatory degenerative disc microenvironment. The objective of this study was to determine the effects of two key design factors, cell type and cell configuration, on the regenerative potential of nucleus pulposus cell (NPC) and mesenchymal stem cell (MSC) constructs. Anabolic and catabolic activity was quantified in constructs of varying cell type (NPCs, MSCs, and a 50:50 co-culture) and varying configuration (individual cells and micropellets). Anabolic and catabolic outcomes were both dependent on cell type. Gene expression of Agg and Col2A1, glycosaminoglycan (GAG) content, and aggrecan immunohistochemistry (IHC), were significantly higher in NPC-only and co-culture groups than in MSC-only groups, with NPC-only groups exhibiting the highest anabolic gene expression levels. However, NPC-only constructs also responded to inflammation and hypoxia with significant upregulation of catabolic genes (MMP-1, MMP-9, MMP-13, and ADAMTS-5). MSC-only groups were unaffected by degenerative media conditions, and co-culture with MSCs modulated catabolic induction of the NPCs. Culturing cells in a micropellet configuration dramatically reduced catabolic induction in co-culture and NPC-only groups. Co-culture micropellets, which take advantage of both cell type and configuration effects, had the most immunomodulatory response, with a significant decrease in MMP-13 and ADAMTS-5 expression in hypoxic and inflammatory media conditions. Co-culture micropellets were also found to self-organize into bilaminar formations with an MSC core and NPC outer layer. Further understanding of these cell type and configuration effects can improve tissue engineering designs. (c) 2016 The Authors.

PMID- 27699838 TI - Biomarkers of exposure to nanosilver and silver accumulation in yellow perch (Perca flavescens). AB - There is a risk of exposure of aquatic organisms to silver nanoparticles (AgNPs) from discharges of municipal and industrial wastewater. In the present study, yellow perch (Perca flavescens) were exposed to environmentally relevant concentrations (1 mg/L and 100 mg/L) of AgNPs and silver ions (Ag+ ) in static renewal experiments conducted over 96 h and 10 d. The greatest accumulation of total Ag occurred in the liver of P. flavescens, and there was >10-fold more accumulation in the treatments with Ag+ relative to the AgNP treatments. Residues of total Ag increased with concentration and duration of exposure in liver, gill, and muscle. Both exposures caused a 2-fold induction of gene expression for metallothionein (mt) in liver tissue after 96 h of exposure and reductions in levels of oxidized glutathione (GSSG) in liver after 10 d of exposure. Both AgNPs and Ag+ decreased the expression of heat-shock proteins (hsp70). Exposure to the high concentration of AgNPs for 10 d significantly increased lipid peroxidation in gill tissue, as indicated by the thiobarbituric acid reactive substances (TBARS) assay. There was a negative correlation between mean levels of GSSG and TBARS for both gill and liver tissue when data for all treatments were combined. It is significant that these biological responses were observed in P. flavescens exposed to AgNPs, even though accumulation of total Ag was at least 10-fold lower relative to the treatments with Ag+ .

AB - BACKGROUND: Onychomycosis (OM) is thought to be a rare disease in children, although there are few epidemiologic studies. METHODS: This 3-year retrospective case series of nearly 400 children seen at Rady Children's Hospital-San Diego (RCHSD) describes the characteristics of OM found in this pediatric population. RESULTS: From 2011 to 2013, the Pediatric and Adolescent Dermatology Clinic at RCHSD saw a total of 36,634 unique patients, of whom 433 were unique patients with OM. Thirty-four patients met exclusion criteria, leaving 399 (1.1%) with a diagnosis of OM by a pediatric dermatologist. Nail cultures were obtained in 242 cases (60.7%), 116 (48.0%) of which were positive. Trichophyton rubrum was the most commonly isolated pathogen, responsible for 106 cases (91.3%) of positive cultures in the cohort. CONCLUSIONS: Our study provides important regional information regarding epidemiologic data in pediatric onychomycosis, highlighting the diagnostic methods most commonly used and the pathogens most frequently encountered in our practice. PMID- 27699840 TI - A semiautomatic method for rapid segmentation of velocity-encoded myocardial magnetic resonance imaging data. AB - PURPOSE: To develop a semiautomatic method for rapid segmentation of myocardial tissue phase mapping (TPM) data. METHODS: Manual segmentation of the myocardium was performed at end-diastole and end-systole. The points in both user-defined masks were then automatically tracked over the entire cardiac cycle using temporal integration of the velocity field. Paths that failed to visit both masks at the expected times were excluded, after which masks for all time points were generated automatically from the accepted paths. Midventricular and basal phase contrast TPM slices from 12 rats were segmented using the proposed method and fully manual segmentation. The results were compared using Dice's metric and Bland-Altman analysis, and interobserver variability was assessed. RESULTS: The semiautomatic method reduced the average user input time from 21 min to 1 min per slice. The Dice metrics between the methods were 0.88 +/- 0.03 (midventricular) and 0.83 +/- 0.06 (basal), and Bland-Altman limits of agreement of peak systolic and diastolic regional velocities were: midventricular: 0.05 +/- 0.65 cm/s, -0.02 +/- 0.42 cm/s, and -0.03 +/- 0.40 cm/s (radial, tangential, longitudinal); basal: -0.04 +/- 0.73 cm/s, 0.03 +/- 0.60 cm/s, and -0.04 +/- 0.48 cm/s (radial, tangential, longitudinal). Interobserver variability following semiautomatic segmentation was lower than for manual segmentation. CONCLUSION: The proposed method reduced the segmentation time substantially and exhibited well-preserved data quality and excellent interobserver limits of agreement.

PMID- 27699842 TI - Percutaneous versus surgical cut-down access in transfemoral transcatheter aortic valve replacement: A meta-analysis. AB - BACKGROUND: The transfemoral (TF) approach has become the preferred approach for transcatheter aortic valve replacement (TAVR) because of its low risk profile. However, the relative safety of the percutaneous approach (PC) compared to surgical cut-down (SC) remains unclear. Our aim was to compare the outcomes between PC versus SC access in patients undergoing TF-TAVR using a meta-analysis. METHODS: We conducted a systematic electronic database search for studies reporting major and minor vascular complications (VC), major and minor bleeding, and perioperative all-cause mortality, in PC versus SC TF-TAVR cases. Complications were reported based on the Valve Academic Research Consortium criteria. A random-effects model was used to calculate odds ratios and 95% confidence intervals. RESULTS: Eight observational cohort studies and one randomized control trial (2513 patients in PC and 1767 patients in SC) were included in the analysis. Major and minor VC, as well as bleeding complications, were comparable between the two approaches. The need for surgical intervention for VC was comparable between PC and SC. There was no difference in perioperative all-cause mortality. CONCLUSIONS: PC and SC have similar safety profiles and outcomes when used appropriately in selected patients. PMID- 27699841 TI - Combining rheology and MRI: Imaging healthy and tumorous brains based on mechanical properties. AB - PURPOSE: It is well known that pathological changes in tissue alter its mechanical properties. This holds also true for brain tissue. In case of the brain, however, obtaining information about these properties is hard due to the surrounding cranial bone. In this paper a novel technique to create an imaging contrast based on the aforementioned properties is presented. METHODS: The method is based on an excitation of the brain induced by a short fall. The response of the brain tissue is measured using a motion sensitive MRI sequence. RESULTS: The new method is tested by measurements on phantom material as well as on healthy volunteers. In a proof of principle experiment the capability of the approach to identify local alterations in the mechanical properties is shown by means of measurements on meningioma patients. CONCLUSION: The presented results show the feasibility of the novel method. Even in this early state of the proposed method, comparisons of measurements on meningioma patients with intraoperative palpation suggest that meningioma tissue responds differently to the excitation depending on their mechanical properties.

PMID- 27699843 TI - Quantitative ultrashort TE imaging of the short-T2 components in skeletal muscle using an extended echo-subtraction method. AB - PURPOSE: To introduce an ultrashort echo time (UTE) based method for quantitative mapping of short-T2 signals in skeletal muscle (SKM) in the presence of fat, with the aim of monitoring SKM fibrosis. METHODS: From a set of at least five UTE images of the same slice, a long- T2* map, a fat-fraction map, and a map of short T2 -signal fraction are extracted. The method was validated by numerical simulations and in vitro studies on collagen solutions. Finaly, the method was applied to image the short-T2 signals in the leg of eight healthy volunteers. RESULTS: The imaged short-T2 -signal fractions in the collagen solutions correlated with their respective collagen concentrations ( R=0.999, P=0.009). Short-T2 tissues such as cortical bone and fasciae were highlighted in the resulting short-T2 fraction maps. A significant fraction of short-T2 signal was systematically observed in the skeletal muscle of all of the subjects (4.5+/ 1.2%). CONCLUSION: The proposed method allows the quantitative imaging of short T2 components in tissues containing fat. By also having the fat-fraction and T2* maps as outcomes, long-T2 suppression is accomplished without requiring modifications to the basic UTE sequence. Although the hypersignal observed in the fasciae suggests that the short-T2 signal observed in SKM might arise from interstitial connective tissue, further investigation is necessary to confirm this statement.

AB - PURPOSE: MR thermometry is critical for safe and effective transcranial focused ultrasound. The current single-slice MR thermometry sequence cannot achieve all desired treatment monitoring requirements. We propose an approach in which the imaging requirements of different aspects of treatment monitoring are met by optimizing multiple sequences. METHODS: Imaging requirements were determined for three stages of MR-guided focused ultrasound brain treatment: 1) focal spot localization, 2) focal spot monitoring, and 3) background monitoring. Multiple echo spiral thermometry sequences were optimized for each set of requirements and then validated with in vivo signal-to-noise ratio measurements and with phantom heating experiments. RESULTS: Each of the proposed sequences obtained better precision than the current two-dimensional Fourier transform (2DFT) thermometry sequence. Five-slice focal spot localization achieved two-fold better resolution with 1.9-fold better precision but two-fold longer acquisition compared to 2DFT. Five-slice focal monitoring achieved 2.1-fold better precision with similar speed but 12% larger voxels than 2DFT. Full-brain background monitoring was demonstrated in both axial (7.1 s) and sagittal (11.4 s) orientations. Phantom heating time curves were consistent across all sequences after correcting for resolution. CONCLUSION: Multiple-echo spiral imaging significantly improves MR thermometry efficiency, enabling multiple-slice monitoring. Optimizing multiple specialized sequences provides better performance than can be achieved by any single sequence. Magn Reson Med 78:508-517, 2017.

AB - BACKGROUND/OBJECTIVES: A combination of narrowband ultraviolet B (NBUVB) phototherapy plus topical tacrolimus has been used in adult vitiligo but has not yet been explored in children. We therefore sought to highlight the efficacy of this synergistic combination in childhood vitiligo. The objective was to study the clinical efficacy and safety of a combination of NBUVB with topical tacrolimus ointment 0.03% in childhood vitiligo. METHOD: In this open-label study, 20 children, 4 to 14 years of age, with symmetrical vitiligo lesions were enrolled for 24 weeks. All were instructed to apply tacrolimus ointment 0.03% on a target patch on the left side of the body twice daily and no topical on a target patch on the right side. The whole body was irradiated with NBUVB three times per week. All patients were examined and the same dermatologist photographed lesions to assess for repigmentation at 4-week intervals. Response was noted as the percentage of repigmentation (none, 0%; poor, 1-25%; moderate, 26-50%; good, 51-75%; excellent, >75%). RESULT: Our study found a statistically significant difference in the mean percentage of repigmentation at 4 and 6 months between combination therapy and NBUVB monotherapy. The mean cumulative dose and average number of exposures for the first clinically visible response were significantly lower with combination therapy. No serious adverse events were noted during the study period. CONCLUSION: Our preliminary data suggest that a combination of NBUVB phototherapy with topical tacrolimus is a highly effective and promising therapeutic option for vitiligo in children, whose treatment options are very limited, but long-term studies are needed to evaluate the future risk of malignancy. PMID- 27699845 TI - Management of older adults with dementia who present to emergency services with neuropsychiatric symptoms. AB - OBJECTIVE: Our aim is to evaluate if and how neuropsychiatric symptoms (NPS) of dementia influence the management and disposition of older adults who present to emergency care settings. METHODS: This is a retrospective cohort study that involved the medical and psychiatric emergency departments of a tertiary academic medical center. Participants included patients >=65 years of age with dementia who presented between 1 February 2012 and 16 July 2014 (n = 347). Subjects with documented NPS (n = 78) were compared with a group of subjects without documented NPS (n = 78) randomly selected from the overall group with dementia. The groups with and without NPS were compared on demographic, clinical, management, and disposition characteristics. RESULTS: Patients with NPS were more likely to have additional diagnostic testing performed and receive psychotropic medications including benzodiazepines and antipsychotics. Significantly fewer patients with NPS (59.0%) returned to their original setting from the emergency department than patients without NPS (76.9%). Among patients with NPS, those who had a motor disturbance were more likely to receive psychotropic medications than patients who did not have a motor disturbance. Depression/dysphoria, anxiety, disinhibition, irritability/lability, and motor disturbance were all associated with transfer from medical to psychiatric emergency department. Patients with depression/dysphoria or anxiety were more likely to be psychiatrically hospitalized. CONCLUSIONS: There are significant differences in the management of dementia with and without NPS in the emergency room setting. Developing and implementing successful methods to manage NPS in the emergency department and outpatient setting could potentially lead to less emergent psychotropic administration and reduce hospitalizations.

AB - Understanding the physical attributes of protein-ligand interfaces, the source of most biological activity, is a fundamental problem in biophysics. Knowing the characteristic features of interfaces also enables the design of molecules with potent and selective interactions. Prediction of native protein-ligand interactions has traditionally focused on the development of physics-based potential energy functions, empirical scoring functions that are fit to binding data, and knowledge-based potentials that assess the likelihood of pairwise interactions. Here we explore a new approach, testing the hypothesis that protein ligand binding results in computationally detectable rigidification of the protein-ligand interface. Our SiteInterlock approach uses rigidity theory to efficiently measure the relative interfacial rigidity of a series of small molecule ligand orientations and conformations for a number of protein complexes. In the majority of cases, SiteInterlock detects a near-native binding mode as being the most rigid, with particularly robust performance relative to other methods when the ligand-free conformation of the protein is provided. The interfacial rigidification of both the protein and ligand prove to be important characteristics of the native binding mode. This measure of rigidity is also sensitive to the spatial coupling of interactions and bond-rotational degrees of freedom in the interface. While the predictive performance of SiteInterlock is competitive with the best of the five other scoring functions tested, its measure of rigidity encompasses cooperative rather than just additive binding interactions, providing novel information for detecting native-like complexes. SiteInterlock shows special strength in enhancing the prediction of native complexes by ruling out inaccurate poses. Proteins 2016; 84:1888-1901. (c) 2016 Wiley Periodicals, Inc. PMID- 27699848 TI - Total mercury and methylmercury concentrations over a gradient of contamination in earthworms living in rice paddy soil. AB - Mercury (Hg) deposited from emissions or from local contamination, can have serious health effects on humans and wildlife. Traditionally, Hg has been seen as a threat to aquatic wildlife, because of its conversion in suboxic conditions into bioavailable methylmercury (MeHg), but it can also threaten contaminated terrestrial ecosystems. In Asia, rice paddies in particular may be sensitive ecosystems. Earthworms are soil-dwelling organisms that have been used as indicators of Hg bioavailability; however, the MeHg concentrations they accumulate in rice paddy environments are not well known. Earthworm and soil samples were collected from rice paddies at progressive distances from abandoned mercury mines in Guizhou, China, and at control sites without a history of Hg mining. Total Hg (THg) and MeHg concentrations declined in soil and earthworms as distance increased from the mines, but the percentage of THg that was MeHg, and the bioaccumulation factors in earthworms, increased over this gradient. This escalation in methylation and the incursion of MeHg into earthworms may be influenced by more acidic soil conditions and higher organic content further from the mines. In areas where the source of Hg is deposition, especially in water logged and acidic rice paddy soil, earthworms may biomagnify MeHg more than was previously reported. It is emphasized that rice paddy environments affected by acidifying deposition may be widely dispersed throughout Asia. Environ Toxicol Chem 2017;36:1202-1210. (c) 2016 SETAC.

Bilateral coronary obstruction is even more unusual but has been reported in conjunction with aortic valve disease, syphilis, and Takayasu's arteritis. To the best of our knowledge, obstruction of both coronaries in a pediatric patient has only been reported once (Ann Thorac Surg, 55, 1993, 1564).

PMID- 27699852 TI - True morphology of mitral regurgitant flow assessed by three-dimensional transesophageal echocardiography. AB - INTRODUCTION: Quantification of mitral regurgitation (MR) by two-dimensional (2D) transthoracic echocardiography (TTE) is based on the analysis of the proximal flow convergence (PFC) and the "vena contracta" (VC). This method assumes geometries and can be misleading. In contrast, three-dimensional (3D) echocardiography directly measures flow volumes and does not assume geometries, which allows for more accurate MR evaluation. AIMS: To report the 3D transesophageal echocardiography (3DTEE) feasibility for MR quantification and evaluate its concordance with 2D echo. METHODS: Twenty-seven consecutive patients undergoing 2D and 3DTEE for presurgical MR evaluation were studied prospectively. MR quantification was performed by classical 2D methods based on PFC. Diameters of the VC in orthogonal planes by 3DTEE were estimated, establishing the VC sphericity index as well as VC area (VCA) by direct planimetry. In case of multiple jets, we calculated the sum of the VCA. RESULTS: MR assessment by 3DTEE was feasible. An adequate concordance between VC measurements by 2D methods (TTE and TEE) was observed; however, there was a poor correlation when compared with 3DTEE. The sphericity index of the VC was: 2.08 (+/-0. 72), reflecting a noncircular VC. CONCLUSIONS: 3DTEE is a feasible method for the assessment of the MR true morphology, allowing a better quantification of MR without assuming any geometry. This method revealed the presence of multiple jets, potentially improving MR evaluation and leading to changes in medical decision when compared to 2D echo assessment.

Global properties of the rest of the protein also play an essential role, determining the structure and fluctuations of the binding site; however, these can be modeled on a coarser level. Similarly, in the most computationally efficient scheme only the solvent hydrating the active site requires atomistic detail. We present a methodology to couple atomistic and coarse-grained protein models, while solvating the atomistic part of the protein in atomistic water. This allows a free choice of which protein and solvent degrees of freedom to include atomistically. This multi-resolution methodology can successfully model stable ligand binding, and we further confirm its validity by exploring the reproduction of system properties relevant to enzymatic function. In addition to a computational speedup, such an approach can allow the identification of the essential degrees of freedom playing a role in a given process, potentially yielding new insights into biomolecular function.

AB - The comprehensive sequence determinants of binding affinity for type I cohesin toward dockerin from Clostridium thermocellum and Clostridium cellulolyticum was evaluated using deep mutational scanning coupled to yeast surface display. We measured the relative binding affinity to dockerin for 2970 and 2778 single point mutants of C. thermocellum and C. cellulolyticum, respectively, representing over 96% of all possible single point mutants. The interface DeltaDeltaG for each variant was reconstructed from sequencing counts and compared with the three independent experimental methods. This reconstruction results in a narrow dynamic range of -0.8-0.5 kcal/mol. The computational software packages FoldX and Rosetta were used to predict mutations that disrupt binding by more than 0.4 kcal/mol. The area under the curve of receiver operator curves was 0.82 for FoldX and 0.77 for Rosetta, showing reasonable agreements between predictions and experimental results. Destabilizing mutations to core and rim positions were predicted with higher accuracy than support positions. This benchmark dataset may be useful for developing new computational prediction tools for the prediction of the mutational effect on binding affinities for protein-protein interactions. Experimental considerations to improve precision and range of the reconstruction method are discussed. Proteins 2016; 84:1914-1928. (c) 2016 Wiley Periodicals, Inc. PMID- 27699859 TI - Acne Fulminans: Case Series and Review of the Literature. AB - Acne fulminans (AF) is a rare manifestation and the most severe form of the entire clinical spectrum of acne. The disease is destructive and is characterized by the sudden onset of painful and ulcerative pustules and systemic symptoms including high fever, hepatomegaly, polyarthralgia, leukocytosis, plaquetose, and increased inflammatory markers and transaminases. Osteolytic lesions in multiple skeletal sites could also be associated. The use of isotretinoin is considered a related trigger, as well as the use and cessation of testosterone, although a bacterial infection, a drug-induced disease, or an intake of anabolic androgenic steroids has been suggested. The treatment of AF is challenging and controversial. The recommended treatment is aggressive and consists of a combination of oral steroids and low doses of isotretinoin, with no consensus at this time. The patient may require several weeks of hospitalization to control the eruption. The cutaneous lesions usually leave scars and milia. We report on two boys and two girls presenting with AF, triggered by isotretinoin in three patients and by an antibiotic in one patient. All the patients treated with corticosteroids and isotretinoin with success. PMID- 27699860 TI - Angioedema After Squaric Acid Treatment in a 6-Year-Old Girl. AB - Alopecia areata (AA) involves the immune-related destruction of hair follicles, resulting in patches of complete hair loss, most often on the scalp. The topical sensitizer squaric acid dibutylester (SADBE) is a popular treatment option given its low side-effect profile, hair regrowth potential, and lack of cross reactivity with other chemicals. We describe a unique case of a 6-year-old girl who developed angioedema after SADBE treatment for AA. PMID- 27699858 TI - Genetic association between RAGE polymorphisms and Alzheimer's disease and Lewy body dementias in a Japanese cohort: a case-control study. AB - BACKGROUND/AIMS: Interaction of receptor for advanced glycation end products (RAGE) with amyloid-beta increases amplification of oxidative stress and plays pathological roles in Alzheimer's disease (AD). Oxidative stress leads to alpha synuclein aggregation and is also a major contributing factor in the pathogenesis of Lewy body dementias (LBDs). Therefore, we aimed to investigate whether RAGE gene polymorphisms were associated with AD and LBDs. METHODS: Four single nucleotide polymorphisms (SNPs)-rs1800624, rs1800625, rs184003, and rs2070600-of the gene were analyzed using a case-control study design comprising 288 AD patients, 76 LBDs patients, and 105 age-matched controls. RESULTS: Linkage disequilibrium (LD) examination showed strong LD from rs1800624 to rs2070600 on the gene (1.1 kb) in our cases in Japan. Rs184003 was associated with an increased risk of AD. Although there were no statistical associations for the other three SNPs, haplotypic analyses detected genetic associations between AD and the RAGE gene. Although relatively few cases were studied, results from the SNPs showed that they did not modify the risk of developing LBDs in the Japanese population. CONCLUSION: Our findings suggested that polymorphisms in the RAGE gene are involved in genetic susceptibility to AD. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27699861 TI - Pediatric Pyoderma Gangrenosum: A Retrospective Review of Clinical Features, Etiologic Associations, and Treatment. AB - BACKGROUND/OBJECTIVES: Pyoderma gangrenosum (PG) is a neutrophilic dermatosis rarely seen in children. Its features have not been well characterized in children. We sought to characterize the clinical features, etiologic associations, and treatment of PG in children younger than 18 years. METHODS: We performed a retrospective review of children younger than 18 years with PG at the Mayo Clinic from January 1976 to August 2013. RESULTS: Thirteen children with PG were identified (n = 8; 62% female). All had ulcerations, with 62% having pustular lesions. Sites of involvement included the trunk (77%), lower extremities (77%), upper extremities (38%), and head and neck (38%). Nine (69%) had an underlying comorbidity, including seven with Crohn's disease (54%), one with juvenile idiopathic arthritis (8%), and one with pyogenic arthritis, pyoderma gangrenosum, and acne syndrome (8%). Treatments included topical or local care (92%) and systemic therapies (85%) such as oral corticosteroids (62%) and sulfasalazine or related 5-aminosalicylate drugs (46%). The clinical course did not correlate with that of the underlying systemic disease and response to treatment varied. CONCLUSION: Pediatric PG has a more varied anatomic distribution and a greater predominance of pustular lesions than PG in adults and a strong association with inflammatory bowel disease.

Numerous therapeutic options have been tried, but effective treatment remains elusive. The sympathetic nervous system has been involved in various painful conditions of neuropathic, vascular, and visceral origin. Sympathetic block is helpful in making a diagnosis and managing pain. We report a case of excellent pain relief after lumbar sympathetic pulsed radiofrequency treatment in a patient with primary erythromelalgia of the lower extremities. This case suggests the viability of pulsed radiofrequency treatment in patients with erythromelalgia.

AB - BACKGROUND AND AIM: Budesonide is a second-generation steroid with prominent topical effects and minimal systemic activity for patients with ulcerative colitis (UC). We perform a systematic review and meta-analysis of randomized placebo-controlled trials to assess the efficacy and safety of budesonide foam in mild-to-moderate distal UC. METHODS: Comprehensive searches were performed to identify all eligible studies. Outcome measures were clinical remission, endoscopic improvement, elimination of rectal bleeding, and adverse events. The risk ratio (RR) with 95% confidence interval (CI) was estimated for each outcome. All statistical analyses were performed in STATA 12.0. RESULTS: Three randomized placebo-controlled trials recruiting 711 patients with mild-to-moderate distal UC were included in this study. No significant bias and heterogeneity was identified. Pooled analyses showed that budesonide foam was significantly superior to placebo for induction of clinical remission (RR = 1.83, 95%CI: 1.41, 2.37; P < 0.001) and endoscopic improvement (RR = 1.44, 95%CI: 1.23, 1.68; P < 0.001), and eliminating rectal bleeding at week 2 (RR = 2.00, 95%CI: 1.50, 2.66; P < 0.001), week 4 (RR = 1.73, 95%CI: 1.42, 2.12; P < 0.001), and week 6 (RR = 1.76, 95%CI: 1.45, 2.14; P < 0.001). No statistically significant difference was observed in the incidence of treatment-related adverse events and therapeutic discontinuation because of adverse events between budesonide foam and placebo. CONCLUSIONS: Budesonide foam is well tolerated and superior to placebo in inducing clinical remission and endoscopic improvement, and eliminating rectal bleeding for mild-to-moderate distal UC. PMID- 27699864 TI - Retrospective Study of Nasal Infantile Hemangiomas: Characteristics, Complications, and Outcomes. AB - BACKGROUND/OBJECTIVES: Nasal infantile hemangiomas (IHs) pose serious medical complications and psychosocial stress if tumor involution is incomplete or prolonged. The objective was to determine which IH characteristics are associated with complications and are predictive of outcome, assessed as the presence of IHs or residual skin changes upon kindergarten entry, to better manage these lesions and counsel families. METHODS: A retrospective chart review of all patients seen in the Division of Pediatric Dermatology at Johns Hopkins Medicine between 2001 and 2014 for nasal IHs (N = 89) was performed. A follow-up telephone interview with parents was conducted in June and July 2014. RESULTS: Complications were observed in 39% of patients. Segmental and indeterminate IHs were more likely to have complications than focal IHs (p = 0.01). Mixed IHs were more likely to ulcerate than deep or superficial IHs (p = 0.01). Eighty percent of patients had treatment and 19% had surgery. Although IHs regressed by kindergarten entry in 70% of patients, 78% of these patients had residual skin changes. Mixed and superficial IHs left more residua than deep IHs (p = 0.04). A statistical comparison of treatments with respect to outcome at kindergarten entry could not be made because subgroups were too small and heterogeneous. CONCLUSION: Nasal IHs had higher rates of complications and treatment than previous reports of IHs at all body sites. Lesions of segmental and indeterminate type and mixed depth should be identified as high risk and treated accordingly. Parents may be counseled that most nasal IHs involute by kindergarten but leave residua and that early referral for treatment may be important for the best outcome. PMID- 27699865 TI - Personality and behavioural changes do not precede memory problems as possible signs of dementia in ageing people with Down syndrome. AB - OBJECTIVE: The objective was to find out whether changes in personality and adaptive functioning or memory processes decline first in ageing people with Down syndrome. METHODS: We measured these variables cross-sectionally in a Dutch sample (22 to 62 years of age) of 68 institutionalised people with Down syndrome. RESULTS: The scores on all the variables except one of the temperament scales were found to decline gradually with increasing age, but deterioration of episodic memory started earlier. CONCLUSIONS: We argued that a subset of our sample suffered from dementia. Furthermore, the data suggested that immediate memory impairment is one of the earliest signs of the disease in people with Down syndrome, just as it is in the general population.

PMID- 27699866 TI - Influences of bicarbonate on processes of enamel subsurface remineralization and demineralization: assessment using micro-Raman spectroscopy and transverse microradiography. AB - In the present study, we investigated, using micro-Raman spectroscopy (Raman) and transverse microradiography, the influence of bicarbonate [sodium hydrogen carbonate (NaHCO3 )] on the effects of carbonate ions in the mineral phase during demineralization (acid resistance test) of subsurface lesions. Baseline lesions were created by demineralizing bovine enamel, and specimens were then exposed to remineralization solutions containing 0, 5, or 50 mM bicarbonate. Acid resistance tests were performed on remineralized and sound enamel specimens. Raman spectra showed that carbonate and phosphate were incorporated into both surface layers and lesion bodies during remineralization in the presence of bicarbonate. Moreover, the presence of bicarbonate did not affect the rates of remineralization, although the average mineral profiles of remineralized enamel differed from those of sound enamel after acid resistance tests. Raman analyses enabled close evaluation of site-specific characteristics of carbonate and phosphate in subsurface lesions. In conclusion, incorporation of carbonate and phosphate ions into enamel subsurface lesions during remineralization does not affect the magnitude of remineralization or acid resistance.

PMID- 27699867 TI - A rapid and robust gradient measurement technique using dynamic single-point imaging. AB - PURPOSE: We propose a new gradient measurement technique based on dynamic single point imaging (SPI), which allows simple, rapid, and robust measurement of k space trajectory. METHODS: To enable gradient measurement, we utilize the variable field-of-view (FOV) property of dynamic SPI, which is dependent on gradient shape. First, one-dimensional (1D) dynamic SPI data are acquired from a targeted gradient axis, and then relative FOV scaling factors between 1D images or k-spaces at varying encoding times are found. These relative scaling factors are the relative k-space position that can be used for image reconstruction. The gradient measurement technique also can be used to estimate the gradient impulse response function for reproducible gradient estimation as a linear time invariant system. RESULTS: The proposed measurement technique was used to improve reconstructed image quality in 3D ultrashort echo, 2D spiral, and multi-echo bipolar gradient-echo imaging. In multi-echo bipolar gradient-echo imaging, measurement of the k-space trajectory allowed the use of a ramp-sampled trajectory for improved acquisition speed (approximately 30%) and more accurate quantitative fat and water separation in a phantom. CONCLUSION: The proposed dynamic SPI-based method allows fast k-space trajectory measurement with a simple implementation and no additional hardware for improved image quality.

AB - Toll-like receptors (TLRs) recognize common structural patterns in diverse microbial molecules and play central roles in the innate immune response. The structures of extracellular domains and their ligand complexes of several TLRs have been determined by X-ray crystallography. Here, we discuss recent advances on structures and activation mechanisms of TLRs. Despite the differences in interaction areas of ligand with TLRs, the extracellular domains of TLRs all adopt horseshoe-shaped structures and the overall M-shape of the TLR-ligand complexes is strikingly similar. The structural rearrangement information of TLRs sheds new light on their ligand-recognition and -activation mechanisms. Proteins 2016; 85:3-9. (c) 2016 Wiley Periodicals, Inc. PMID- 27699868 TI - Toward elucidating the heat activation mechanism of the TRPV1 channel gating by molecular dynamics simulation. AB - As a key cellular sensor, the TRPV1 cation channel undergoes a gating transition from a closed state to an open state in response to various physical and chemical stimuli including noxious heat. Despite years of study, the heat activation mechanism of TRPV1 gating remains enigmatic at the molecular level. Toward elucidating the structural and energetic basis of TRPV1 gating, we have performed molecular dynamics (MD) simulations (with cumulative simulation time of 3 MUs), starting from the high-resolution closed and open structures of TRPV1 solved by cryo-electron microscopy. In the closed-state simulations at 30 degrees C, we observed a stably closed channel constricted at the lower gate (near residue I679), while the upper gate (near residues G643 and M644) is dynamic and undergoes flickery opening/closing. In the open-state simulations at 60 degrees C, we found higher conformational variation consistent with a large entropy increase required for the heat activation, and both the lower and upper gates are dynamic with transient opening/closing. Through ensemble-based structural analyses of the closed state versus the open state, we revealed pronounced closed to-open conformational changes involving the membrane proximal domain (MPD) linker, the outer pore, and the TRP helix, which are accompanied by breaking/forming of a network of closed/open-state specific hydrogen bonds. By comparing the closed-state simulations at 30 degrees C and 60 degrees C, we observed heat-activated conformational changes in the MPD linker, the outer pore, and the TRP helix that resemble the closed-to-open conformational changes, along with partial formation of the open-state specific hydrogen bonds. Some of the residues involved in the above key hydrogen bonds were validated by previous mutational studies. Taken together, our MD simulations have offered rich structural and dynamic details beyond the static structures of TRPV1, and promising targets for future mutagenesis and functional studies of the TRPV1 channel.

AB - BACKGROUND: Sulphur mustard (SM) is an alkylating chemical warfare agent which causes acute and chronic injuries to the eyes, skin, lung and respiratory tract. OBJECTIVE: We aimed to investigate the relationship between SM poisoning and Mycosis fungoides (MF) as a late consequence. MATERIAL AND METHODS: In this retrospective study, the medical files of 1100 Iranian veterans confirmed to have exposure to SM agent during the Iraq-Iran war of the 1980s were reviewed. RESULTS: All 10 cases with MF were confirmed by clinical and histopathological examinations. The mean age of the studied subjects was 43.3 +/- 9.8 (years). In comparison to MF incidence rate in Iranian general population (0.39/100 000 person-years), we found an incidence rate of 0.799/100 000 person-years for MF among those who had short-term exposure to SM. The most common sites for SM lesions were flexural and thin skin areas. The main limitation was the retrospective design. CONCLUSION: This study indicates that the risk of MF in those exposed to SM may increase over time. Therefore, their follow-up is recommended. PMID- 27699872 TI - Are myelodysplastic syndromes underdiagnosed in Poland? A report by the Polish Adult Leukaemia Group. AB - OBJECTIVES: The epidemiology of myelodysplastic syndromes (MDS) differs among countries. Here, we present the first epidemiological indices determined for Poland. METHODS: Twenty-one haematological centres participated in the study. Patients diagnosed with MDS and acute myeloid leukaemia (AML) with 20-29% blasts were enrolled. Data collection was conducted for strictly predefined period. RESULTS: The overall crude incidence rate for all MDS subtypes was 1.95 (95% CI, 1.81-2.09) per 100 000 person-years: 2.46 (95% CI, 2.24-2.69) for males and 1.47 (95% CI, 1.31-1.65) for females; after excluding AML cases, the indices were as follows: 2.35 (95% CI, 2.08-2.66) for males and 1.27 (95% CI, 1.08-1.5) for females. Prevalence rate was 6.2 per 100 000 persons (95% CI, 5.96-6.45), that is 6.86 (95% CI, 6.49-7.24) for males and 5.58 (95% CI, 5.26-5.92) for females. Both incidence and prevalence increased with increasing age. The most frequently diagnosed MDS subtype was refractory cytopenia with multilineage dysplasia (RCMD), responsible for 30.3% of all newly diagnosed MDSs. CONCLUSIONS: RCMD is the most frequent MDS subtype in Poland. Incidence and prevalence indices are lower than those reported for other populations, which probably results from inadequate diagnosis of potential cases of this disease. PMID- 27699873 TI - Semen supplementation with palmitoleic acid promotes kinematics, microscopic and antioxidative parameters of ram spermatozoa during liquid storage. AB - The purpose of the present experiment was to investigate the protective effects of palmitoleate on the quality of ram semen during low temperature liquid storage. Ejaculates were collected using the artificial vagina from four Qezel rams twice a week. Ejaculates were pooled, diluted with Tris-egg yolk extender without palmitoleate (control) or supplemented with 0.125 (P 0.125), 0.25 (P 0.25), 0.5 (P 0.5) and 1 (P 1) mM palmitoleate at a final concentration of 500 * 106 spermatozoa/ml. Total motility and forward progressive motility (FPM) as well as other spermatozoa kinematics were evaluated by computer-assisted sperm analysis. Moreover, viability and membrane functionality were determined in the spermatozoa. Additionally, amounts of malondialdehyde (MDA), total antioxidant activity (AOA), nitric oxide (NO) and superoxide dismutase (SOD) activities were evaluated in the medium and spermatozoa at 0, 24, 48 and 72 hr of storage. The palmitoleate supplementation resulted in a significant (p < .05) increase in total motility and FPM with the highest increase at 0.5 mM concentration for 72 hr. P 0.5 group also resulted in the highest percentage of membrane-intact spermatozoa (76.60 +/- 1.95%) and viability (75.81 +/- 1.34%) at 72 hr (p < .05). The amounts of MDA and NO were lower in P 0.125, P 0.25 and P 0.5 groups compared to control at 48 hr and 72 hr (p < .05). Higher amounts of AOA were obtained in palmitoleate-treated groups in medium and spermatozoa during storage time (p < .05). Furthermore, palmitoleate supplementation increased the SOD activities in spermatozoa compared to the control (p < .05). The results of the present experiment reveal that supplementation with 0.5 mM palmitoleate improves ram spermatozoa motion characteristics, AOA levels and SOD activities during liquid storage. Then, palmitoleate could be used as an antioxidant source during liquid storage of ram semen.

PMID- 27699875 TI - Tomoelastography of the abdomen: Tissue mechanical properties of the liver, spleen, kidney, and pancreas from single MR elastography scans at different hydration states. AB - PURPOSE: To develop a compact magnetic resonance elastography (MRE) protocol for abdomen and to investigate the effect of water uptake on tissue stiffness in the liver, spleen, kidney, and pancreas. METHODS: Nine asymptomatic volunteers were investigated by MRE before and after 1 liter water uptake. Shear-wave excitation at four frequencies was transferred to the abdomen from anterior and posterior directions using pressurized air drivers. Tomographic representations of shear wave speed were produced by analysis of multifrequency wave numbers in axial and coronal images acquired within four breath-holds or under free breathing, respectively. RESULTS: Pre and post water, stiffness of the spleen (pre/post: 2.20 +/- 0.10/2.06 +/- 0.18 m/s) and kidney (pre/post: 1.93 +/- 0.22/1.97 +/- 0.23 m/s) was higher than in the liver (pre/post: 1.36 +/- 0.10/1.38 +/- 0.13 m/s) and pancreas (pre/post: 1.20 +/- 0.12/1.20 +/- 0.08 m/s), all P < 0.01. Accounting for four drive frequencies, water drinking only changed the splenic stiffness (-6%, P = 0.03), whereas in the frequency range from 50 to 60 Hz the effect became significant also in the pancreas (-6%, P = 0.04) and liver (+3%, P = 0.03). Elastograms of the kidney in coronal view clearly depicted higher stiffness in cortex than in medulla. CONCLUSION: Tomoelastography reveals sensitivity of tissue mechanical properties to the hydration state of multiple abdominal organs within one scan and in unprecedented resolution of anatomical details.

PMID- 27699876 TI - Estimating Time-averaged Serum Urea Nitrogen Concentration during Various Urine Collection Periods: A Prediction Equation for Thrice Weekly and Biweekly Dialysis Schedules. AB - Residual kidney urea clearance in dialysis patients typically is calculated as the per minute excretion of urea nitrogen, obtained during the 24-48 hour collection period that usually ends just prior to a dialysis session, divided by the time-averaged serum water urea nitrogen concentration during the collection period. This concentration is difficult to estimate unless a formal kinetic modeling program is being used. We used a urea kinetic modeling program to derive an equation to estimate the time-averaged serum water concentration during urine collection periods of various lengths collected during various interdialytic intervals, for 3/week or 2/week dialysis schedules. The equation to predict time averaged serum water urea nitrogen concentration during the collection period was a function of the ratio of the duration of the predialysis collection period to the duration of the interdialytic interval during which the collection was accomplished, as well as the urea reduction ratio and predialysis serum urea nitrogen concentration of the dialysis session immediately following the end of the collection period. PMID- 27699877 TI - Laparoendoscopic single-site surgeries: A multicenter experience of 469 cases in Japan. AB - OBJECTIVE: To report on a multi-institutional series of non-robotic urological laparoendoscopic single-site surgery in Japan. METHODS: Consecutive cases of laparoendoscopic single-site surgery carried out between February 2009 and December 2012 at nine academic institutions were included. We examined the surgical outcomes, including conversion and complications rates. RESULTS: Four hundred and sixty-nine cases were included in the analysis. The most common procedure was adrenalectomy (n = 177) and the second most common procedure was radical nephrectomy (n = 143). The procedures also included nephroureterectomy (n = 40), living donor nephrectomy (n = 40), pyeloplasty (n = 30), urachal remnant excision (n = 9), simple nephrectomy (n = 7), radical prostatectomy (n = 6) and others (n = 17). The access sites included umbilicus (n = 248, 53%) and other sites (n = 221, 47%). A transperitoneal approach was used in 385 cases (82%), and retroperitoneal approach in 84 cases (18%). The median operation time of all procedures was 198 min. Conversion to reduced port surgery, conventional laparoscopy, or open surgery was noted in 27 cases (5.8%), 12 cases (2.6%), and two cases (0.4%), respectively, with an overall conversion rate of 8.7%. Intraoperative complications occurred in 10 cases (2.1%). Post-operative complications were noted in 29 cases (6.2%), including five major complications (1.1%). No mortality was recorded in this series. CONCLUSIONS: Non-robotic laparoendoscopic single-site surgery is technically feasible and safe for various urologic diseases in Japan. Furthermore, urological laparoendoscopic single-site surgery is a promising minimally invasive surgical option that is feasible for experienced urological surgeons in intermediate-volume centers as well as high volume centers. PMID- 27699878 TI - Simulation of Electronic Circular Dichroism of Nucleic Acids: From the Structure to the Spectrum. AB - We present a quantum mechanical (QM) simulation of the electronic circular dichroism (ECD) of nucleic acids (NAs). The simulation combines classical molecular dynamics, to obtain the structure and its temperature-dependent fluctuations, with a QM excitonic model to determine the ECD. The excitonic model takes into account environmental effects through a polarizable embedding and uses a refined approach to calculate the electronic couplings in terms of full transition densities. Three NAs with either similar conformations but different base sequences or similar base sequences but different conformations have been investigated and the results were compared with experimental observations; a good agreement was seen in all cases. A detailed analysis of the nature of the ECD bands in terms of their excitonic composition was also carried out. Finally, a comparison between the QM and the DeVoe models clearly revealed the importance of including fluctuations of the excitonic parameters and of accurately determining the electronic couplings. This study demonstrates the feasibility of the ab initio simulation of the ECD spectra of NAs, that is, without the need of experimental structural or electronic data. PMID- 27699879 TI - 3D in utero quantification of T2* relaxation times in human fetal brain tissues for age optimized structural and functional MRI. AB - PURPOSE: Maximization of the blood oxygen level-dependent (BOLD) functional MRI (fMRI) contrast requires the echo time of the MR sequence to match the T2* value of the tissue of interest, which is expected to be higher in the fetal brain compared with the brain of a child or an adult. METHODS: T2* values of the cortical plate/cortical gray matter tissue in utero in healthy fetuses from mid gestation onward (20-36 gestational weeks) were measured using 3D T2* maps calculated from 2D dual-echo T2*-weighted data corrected for between-slice motion and reconstructed in 1.0 mm3 isotropic resolution from a sequence of multiple time points, together with 1.0 mm3 isotropic resolution T2-weighted structural data. RESULTS: Mean T2* relaxation times of the cortical tissue were about twice as high as those reported previously in adults. In a supporting experiment applying single seed analysis, default mode and auditory networks appeared better localized and less noisy while using an echo time of 100 ms versus 43 ms. The results of the previous study reporting a trend for T2* values to decrease with fetal age were reproduced and extended to include cortical tissues and subjects in earlier gestation (20-26 gestational weeks). CONCLUSION: The first measurement of T2* values in fetal cortical tissues suggested the appropriate echo time range for fetal BOLD fMRI protocol optimization to be 130-190 ms.

PMID- 27699880 TI - Impact of UVA on pruritus during UVA/B phototherapy of inflammatory skin diseases: a randomized double-blind study. AB - BACKGROUND: Narrowband (TL-01) UVB phototherapy (UVB nb) is effective in treating inflammatory skin disease. The addition of UVA is traditionally advocated to reduce pruritus, but lacks evidence for this recommendation. OBJECTIVES: The aim of this study was to assess the effect of UVB nb and UVA phototherapy in combination compared against UVB nb monotherapy on pruritus, disease activity and quality of life. METHODS: In this double-blind randomized clinical trial, 53 patients suffering from inflammatory skin diseases with pronounced itching (Visual Analogue Scale (VAS) for pruritus >=5) were randomized into two treatment groups. One group received UVB nb (311 nm) phototherapy alone and another group received a combination of UVB nb and UVA (320-400 nm) phototherapy. UV therapy was performed three times per week over 16 weeks. Pruritus (VAS and 5-D itch score), disease activity and quality of life (Dermatology Life Quality Index, DLQI) were assessed at baseline and weeks 4, 8, 12 and 16. RESULTS: In both treatment groups, there was a reduction in pruritus scores, disease activity and DLQI. No difference in pruritus score, disease activity and quality of life could be detected between the group receiving UVB nb alone and those receiving UVB nb combined with UVA. CONCLUSIONS: Phototherapy with UVB nb alone, and UVB nb combined with UVA are equally effective in treating inflammatory skin disease and indifferent in reducing disease-associated pruritus. Given this non-inferiority for UVB nb monotherapy, the recommendation of adding UVA to UVB nb phototherapy for pruritic inflammatory skin disease should be abandoned.

PMID- 27699881 TI - Structural basis of reversine selectivity in inhibiting Mps1 more potently than aurora B kinase. AB - Monopolar spindle 1 (Mps1, also known as TTK) is a protein kinase crucial for ensuring that cell division progresses to anaphase only after all chromosomes are connected to spindle microtubules. Incomplete chromosomal attachment leads to abnormal chromosome counts in the daughter cells (aneuploidy), a condition common in many solid cancers. Therefore Mps1 is an established target in cancer therapy. Mps1 kinase inhibitors include reversine (2-(4-morpholinoanilino)-6 cyclohexylaminopurine), a promiscuous compound first recognized as an inhibitor of the Aurora B mitotic kinase. Here, we present the 3.0-A resolution crystal structure of the Mps1 kinase domain bound to reversine. Structural comparison of reversine bound to Mps1 and Aurora B, indicates a similar binding pose for the purine moiety of reversine making three conserved hydrogen bonds to the protein main chain, explaining the observed promiscuity of this inhibitor. The cyclohexyl and morpholinoaniline moieties of reversine however, have more extensive contacts with the protein in Mps1 than in Aurora B. This is reflected both in structure based docking energy calculations, and in new experimental data we present here, that both confirm that the affinity of reversine towards Mps1 is about two orders of magnitude higher than towards Aurora B. Thus, our data provides detailed structural understanding of the existing literature that argues reversine inhibits Mps1 more efficiently than Aurora B based on biochemical and in-cell assays.

AB - PURPOSE: We assessed the accuracy of quantitative susceptibility mapping in a gadolinium balloon phantom with a large range of susceptibility values and imaging resolutions at 1.5 and 3 Tesla (T). THEORY AND METHODS: The phantom contained sources with susceptibility values of 0.4, 0.8, 1.6, and 3.2 ppm and was imaged at isotropic resolutions of 0.7, 0.8, 1.2, and 1.8 mm. Numerical simulations were performed to match the experimental findings. Voxel sensitivity effects were used to explain the susceptibility underestimations. RESULTS: Both phantom data and simulation demonstrated that systematic underestimation of the susceptibility values increased with voxel size, field strength, and object susceptibility. CONCLUSION: The underestimation originates from the signal formation in a voxel, which can be described by the voxel sensitivity function. The amount of underestimation is thus affected by imaging resolution, magnitude contrast, image filtering, and details of the susceptibility inclusions such as the susceptibility value and geometry. High-resolution imaging is therefore needed for accurate reconstruction of QSM values, especially at higher susceptibilities. Magn Reson Med 78:1080-1086, 2017.

AB - Zoocin A is a Zn-metallopeptidase secreted by Streptococcus zooepidemicus strain 4881. Its catalytic domain is responsible for cleaving the D-alanyl-L-alanine peptide bond in streptococcal peptidoglycan. The solution NMR structure of the Cys74 to Ala74 mutant of the recombinant catalytic domain (rCAT C74A) has been determined. With a previous structure determination for the recombinant target recognition domain (rTRD), this completes the 3D structure of zoocin A. While the structure of rCAT C74A resembles those of the catalytic domains of lysostaphin and LytM, the substrate binding groove is wider and no tyrosine residue was observed in the active site.

AB - OBJECTIVE: The aim of this study was to evaluate the soft tissue histomorphometric composition around implant abutments comparing two different materials, titanium (Ti) and zirconia (ZrO2 ). MATERIAL AND METHODS: Twelve implants were placed at bone level in the mandible of six beagle dogs (one in each side). At the same day of surgery one titanium abutment was screwed to the implant in one side (control group) and a zirconia abutment was screwed in the contralateral side. Nine months after implant/abutments placement, animals were sacrificed for histological analysis. Descriptive analysis was calculated for each variable and Wilcoxon test was applied to evaluate histomorphometric variables. RESULTS: At the end of the study the soft tissue dimension at Ti and ZrO2 were similar in all counterparts: biological width, the length of the barrier epithelium, length of the connective tissue, and the percentage of collagen fibers density. However, the percentage of blood vessels was higher for the Ti in comparison to ZrO2 (5.11% +/- 1.70 and 2.23% +/- 0.98, respectively [P = 0.016]). CONCLUSIONS: Peri-implant soft tissue histomorphology composition was similar in implant abutments made of ZrO2 and titanium after 9 months of healing.

PMID- 27699888 TI - Carbon isotope alteration during the thermal maturation of non-flowering plant species representative of those found within the geological record. AB - RATIONALE: The carbon isotope (delta13 C value) composition of fossil plant material is routinely used as a proxy of past climate and environment change. However, palaeoclimate interpretation requires assumptions about the stability of delta13 C values in plant material during its decomposition and incorporation into sediments. Previous work on modern angiosperm species shows delta13 C changes of several per mille during simulated decomposition experiments. However, no such tests have been undertaken on non-flowering plants, which are found extensively within the geological record. These plants have distinctly different cellulose-to-lignin ratios from those of their angiosperm counterparts, potentially creating hitherto unknown variations in the original to fossil delta13 C signatures. METHODS: To test the extent of delta13 C change during decomposition we have subjected a number of plants, representing more basal, non flowering plant lineages (cycads, ferns, horsetails and dawn redwood), to artificial decay using a hydrothermal maturation technique at two temperatures over periods of up to 273 hours. Subsamples were extracted every 12-16 hours and analysed for their delta13 C and %C values using a Carlo Erba 1500 elemental analyser, and VG TripleTrap and Optima mass spectrometers. RESULTS: The %C values increased for all samples through the maturation process at both temperatures with the largest increases observed within the first 24 hours. Decreases in delta13 C values were observed for all plants at 300 degrees C and for two of the species at the lower temperature (200 degrees C). The maximum shift in the delta13 C value related to experimental decomposition was -0.900/00 (horsetail), indicating a preferential loss of 13 C during thermal maturation. CONCLUSIONS: The reduction in the delta13 C value potentially suggests a preferential loss of isotopically heavier cellulose in relation to the isotopically lighter lignin component during maturation. The isotopic offset observed here (<0.90/00) means that palaeoclimatic interpretation of delta13 C values from non-flowering plant material within the geological record remains robust, but only where interpretations are based on variations in delta13 C values greater than 10/00.

AB - Kir2.1 (also known as IRK1) plays key roles in regulation of resting membrane potential and cell excitability. To achieve its physiological roles, Kir2.1 performs a series of conformational transition, named as gating. However, the structural basis of gating is still obscure. Here, we combined site-directed mutation, two-electrode voltage clamp with molecular dynamics simulations and determined that H221 regulates the gating process of Kir2.1 by involving a weak interaction network. Our data show that the H221R mutant accelerates the rundown kinetics and decelerates the reactivation kinetics of Kir2.1. Compared with the WT channel, the H221R mutation strengthens the interaction between the CD- and G loops (E303-R221) which stabilizes the close state of the G-loop gate and weakens the interactions between C-linker and CD-loop (R221-R189) and the adjacent G loops (E303-R312) which destabilizes the open state of G-loop gate. Our data indicate that the three pairs of interactions (E303-H221, H221-R189 and E303 R312) precisely regulate the G-loop gate by controlling the conformation of G loop. Proteins 2016; 84:1929-1937.

AB - INTRODUCTION: Available literature suggests there is a transient drop in implant stability from approximately week 0 to week 3-4 as a result of peri-implant bone remodeling as it transitions from a primary, mechanical stability to a secondary, biological stability. Research investigating the influence of macro-thread design on this process is scant. AIM: The specific aim of this study was to evaluate the role of macro-thread design on implant stability in the early post-operative healing period using resonance frequency analysis (RFA). MATERIAL AND METHODS: Seven patients, each missing at least two posterior teeth in the same arch, were included in the study. Three patients qualified for four implants resulting in a total of 10 matched pairs. All sites were healed (>6 months), non-grafted sites with sufficient bone to place implants. Each site in a matched pair was randomly assigned to receive either a control (Megagen EZ Plus Internal; EZ) or test (Megagen AnyRidge; AR) implant. The test implant incorporates a novel thread design with a wide thread depth and increased thread pitch. RFA was used to determine implant stability quotient (ISQ) values for each implant at the time of placement and weekly for the first 8 weeks. RESULTS: Implants consistently achieved a relatively high insertion torque (30-45 N/cm) and high initial ISQ value (79.8 +/- 1.49). Baseline ISQ values for test (AR; 79.55 +/- 1.61) and control (EZ; 80.05 +/- 1.37) implants were similar. A general pattern of stability from baseline through all eight follow-up evaluations was observed for the test implants. A pattern of decreasing ISQ values was observed for the control implants across the early follow-up evaluations up to week four, where the value plateaued. There was a statistically significant main effect due to implant type (P < 0.01) and a statistically significant interaction between implant type and time (P < 0.01), indicating that the test and control implants performed differently at certain time points. CONCLUSIONS: Within the limitations of this study, macro-thread design appears to play a role in implant stability in the early post-operative healing period as assessed by RFA. These findings may have important implications related to immediate or early loading protocols. PMID- 27699891 TI - Sweet Structural Signatures Unveiled in Ketohexoses. AB - The conformational behaviour of naturally occurring ketohexoses has been revealed in a supersonic expansion by Fourier transform microwave spectroscopy coupled with a laser ablation source. Three, two and one conformers of d-tagatose, d psicose and l-sorbose, respectively, have been identified by their rotational constants extracted from the analysis of the spectra. Singular structural signatures involving the hydroxyl groups OH(1) and OH(2) have been disentangled from the intricate intramolecular hydrogen bond networks stabilising the most abundant conformers. The present results place the old Shallenberger and Kier sweetness theories on a firmer footing.

AB - The performance of an organic electronic device is significantly influenced by the anisotropic molecular structure in the film, which has long been difficult to predict especially for a solution process. In the present study, a zinc tetraphenylporphyrin (ZnTPP) thin film prepared by a solution process was chosen to comprehensively explore the molecular-arrangement mechanism as a function of representative film-preparation parameters: solvent, film-preparation technique, and thermal annealing. The anisotropic structure was first analyzed by using a combination of infrared p-polarized multiple-angle incidence resolution spectrometry (pMAIRS) and grazing incidence X-ray diffraction (GIXD), which readily revealed the molecular orientation and crystal structure, respectively. As a result, the real dominant factor was found to be the evaporation time of the solvent that determines the initial two different molecular arrangements, types-I and -II, while the thermal annealing was found to play an additional role of improving the molecular order. The correlation between the molecular orientation and the crystal structure was also revealed through the individual orientation analysis of the porphyrin and phenyl rings.

AB - OBJECTIVES: The impact of sex and subsistence on fluctuating and directional asymmetry patterns was tested among !Kung San and Kavango people from northern Namibia. METHODS: Fluctuating and directional asymmetry from 6 paired traits were measured in a sample of 236 !Kung San and 248 Kavango people aged 18 to 65 years in the Kavango district and the Nyae-Nyae area of northern Namibia. Signed asymmetry, absolute and relative asymmetry, as well as composite fluctuating and directional asymmetry, were calculated. RESULTS: Males of both ethnic groups exhibited higher fluctuating asymmetry in comparison to their female counterparts. Marked differences in directional asymmetry of the upper extremities were found between !Kung San and Kavango people. The !Kung San people showed a significantly higher directional asymmetry than the Kavango people. CONCLUSIONS: Foraging subsistence increased directional asymmetry of the upper extremities among males as well as females. In contrast, higher fluctuating asymmetry-indicating a higher degree of developmental instability-was found among males independent of subsistence group. PMID- 27699893 TI - Mapping the interactions of adenoviral E1A proteins with the p160 nuclear receptor coactivator binding domain of CBP. AB - Many viruses deregulate the cell and force transcription of viral genes by competing with cellular proteins for binding to the transcriptional co-activators CREB-binding protein (CBP) and p300. Through its interactions with CBP/p300 and the retinoblastoma protein, the adenovirus (AdV) early region 1A (E1A) oncoprotein hijacks the cell cycle and, in rodents, transforms the cell; the mechanistic and structural basis for these effects remain unclear. In this study we compare the affinity of protein constructs from the E1A proteins from two adenovirus serotypes, non-oncogenic AdV5 and highly oncogenic AdV12, for binding to the nuclear receptor coactivator binding domain (NCBD) of CBP. NMR spectra show that the E1A constructs from both serotypes are intrinsically disordered in the free state and that each contains three homologous binding sites for the NCBD, one in the N-terminal region and two within conserved region 1 (CR1) of E1A. The binding sites in CR1 correspond to the motifs that bind the retinoblastoma protein and the TAZ2 domain of CBP/p300. The E1A and NCBD peptides fold synergistically upon complex formation. Binding affinities determined from NMR titrations show that, although the overall affinities for AdV5 and AdV12 E1A are comparable, there are significant differences between the two E1A serotypes in the relative strength with which their constituent interaction motifs bind to the NCBD. The individual E1A interaction motifs were unable to compete effectively with p53 for binding to the NCBD and both the N-terminal region and CR1 region of E1A are required for efficient competition with p53.

PMID- 27699895 TI - Influence of abutment material on peri-implant soft tissues in anterior areas with thin gingival biotype: a multicentric prospective study. AB - PURPOSE: The aim of the present clinical trial was to analyze, through spectrophotometric digital technology, the influence of the abutment material on the color of the peri-implant soft tissue in patients with thin gingival biotype. MATERIAL AND METHODS: Thirty-seven patients received an endosseous dental implant in the anterior maxilla. At time of each definitive prosthesis delivery, an all ceramic crown has been tried on gold, titanium and zirconia abutment. Peri implant soft-tissue color has been measured through a spectrophotometer after the insertion of each single abutment. Also facial peri-implant soft-tissue thickness was measured at the level of the implant neck through a caliper. A specific software has been utilized to identify a standardized tissue area and to collect the data before the statistical analysis in Lab* color space. DeltaE parameters of the selected abutments were tested for correlation with mucosal thickness. Pearson correlation test was used. RESULTS: Only 15 patients met the study inclusion criteria on peri-implant soft-tissue thickness. Peri-implant soft tissue color was different from that around natural teeth, no matter which type of restorative material was selected. Measurements regarding all the abutments were above the critical threshold of DeltaE 8.74 for intraoral color distinction by the naked eye. The DeltaE mean values of gold and zirconium abutments were similar (11.43 and 11.37, respectively) and significantly lower (P = 0.03 and P = 0.04, respectively) than the titanium abutment (13.55). In patients with a facial soft-tissue thickness <=2 mm, the DeltaE mean value of gold and zirconia abutments was significantly lower than that of titanium abutments (P = 0.03 and P = 0.04, respectively) and much more close to the reference threshold of 8.74. CONCLUSIONS: For peri-implant soft tissue of <=2 mm, gold or zirconia abutments could be selected in anterior areas treatment. Moreover, the thickness of the peri-implant soft tissue seemed to be a crucial factor in the abutment impact on the color of soft tissues with a thickness of <=2 mm. PMID- 27699897 TI - Childhood body mass is positively associated with cesarean birth in Yucatec Maya subsistence farmers. AB - OBJECTIVE: The epidemiologic link between cesarean birth and childhood obesity is unresolved, partly because most studies come from industrialized settings where many post-birth factors affect the risk for obesity. We take advantage of an unusual ethnographic situation where hospital and cesarean birth modes have recently been introduced among Yucatec Maya subsistence farmers, but young children have had minimal exposure to the nutritional transition. While we expect to find very low rates of childhood obesity, we predict that cesarean-born children will be larger and heavier than vaginally born children. METHODS: Weight and height were collected monthly on 108 children aged 0-5 (3576 observations total). Birth mode and birthweight were collected by maternal interview. Data were analyzed using linear mixed models that compare child growth [Maya population-specific Z-scores for weight-for-age and body mass index-for-age (WAZ and BMIZ)] in cesarean and vaginally born children aged 0-5 years. RESULTS: The cesarean rate was 20%, no children were obese, and 5% were overweight. Cesarean birth was a significant predictor of child WAZ and BMIZ after accounting for maternal effects, child birthweight, and sex. Children who were born by cesarean to mothers with high BMI had the highest WAZ of all children by 5 years of age, and the highest BMIZ of all children at all ages. CONCLUSION: Cesarean-born Maya children had higher BMI than vaginally born children, even in the absence of many known confounding factors that contribute to childhood obesity. Child growth was most sensitive to birth mode when mothers had high BMI.

AB - The luminescent MOF [(CH3 )2 NH2 ]2 [(Zn2 O)L]?5 DMF (NENU-519, NENU=Northeast Normal University) with a zeolite BCT topology was successfully synthesized. It is a rare example of a two-fold interpenetrated framework with a zeolite topology. NENU-519 demonstrates the ability to selectively adsorb cationic dyes. Furthermore we developed Rh6@NENU-519 (Rh6=Rhodamine 6G) as a dual-emitting sensor for probing different volatile organic molecules (VOMs) due to an energy transfer between L and the dye. The composite can be used to distinguish the isomers of o-, m-, and p-xylene and ethylbenzene using the emission-peak-height ratios of L to the dye as detectable signals, in which the readout signals are involved in the interactions between the dye@MOF composite and the guest analytes. Moreover, Rh6@NENU-519 can serve as a luminescent switch for the detection of different aromatic compounds, like benzene, benzene substituted with different groups, and pyridine. In other words, the Rh6@NENU-519 composite can be used as molecular decoder of the structural information of different VOMs into recognizable luminescent signals. Hopefully this work will open a new corridor to develop luminescent guest@MOF composites as sensors for practical applications. PMID- 27699898 TI - Adipose tissue regulates insulin sensitivity: role of adipogenesis, de novo lipogenesis and novel lipids. AB - Obesity, the major cause of the current global epidemic of type 2 diabetes (T2D), induces insulin resistance in peripheral insulin target tissues. Several mechanisms have been identified related to cross-talk between adipose tissue, skeletal muscle and liver. These mechanisms involve both increased free fatty acid release and altered secretion of adipokines from adipose tissue. A major determinant of metabolic health is the ability of subcutaneous adipose tissue (SAT) to store excess fat rather than allowing it to accumulate in ectopic depots including liver (i.e. in nonalcoholic fatty liver disease), muscle and heart, or in epicardial/pericardial and visceral fat depots which promote the metabolic complications of obesity. The ability to recruit and differentiate precursor cells into adipose cells (adipogenesis) in SAT is under genetic regulation and is reduced in high-risk individuals who have first-degree relatives with T2D. Early recruitment of new adipose cells is dependent on the cross-talk between canonical WNT and BMP4 signalling; WNT enhances their undifferentiated and proliferative state whereas BMP4 induces their commitment to the adipogenic lineage. Dysregulation of these signalling pathways is associated with impaired adipogenesis and impaired ability to respond to the need to store excess lipids in SAT. This leads to hypertrophic, dysfunctional and insulin-resistant adipose cells with a reduced content of GLUT4, the major insulin-regulated glucose transporter, which in turn reduces adipose tissue glucose uptake and de novo lipogenesis. We recently identified that reduced GLUT4 and lipogenesis in adipocytes impairs the synthesis of a novel family of lipids secreted by adipose tissue (and potentially other tissues), branched fatty acid esters of hydroxy fatty acids (FAHFAs). FAHFAs have beneficial metabolic effects, including enhancing insulin-stimulated glucose transport and glucose-stimulated GLP1 and insulin secretion, as well as powerful anti-inflammatory effects. FAHFA levels are reduced in subcutaneous adipose tissue in insulin-resistant individuals, and this novel family of lipids may become of future therapeutic use. PMID- 27699900 TI - Pretreatment with beta-adrenergic receptor agonists facilitates induction of LTP and sharp wave ripple complexes in rodent hippocampus. AB - Norepinephrine, is involved in the enhancement of learning and memory formation by regulating synaptic mechanisms through its ability to activate pre- and post synaptic adrenergic receptors. Here we show that beta-agonists of norepinephrine facilitate the induction of both associational LTP and sharp wave ripples (SPW Rs) in acute slices of rat hippocampus in area CA3. Surprisingly, this facilitating effect persists when slices are only pretreated with beta-receptor agonists followed by wash out and application of the unspecific beta adrenoreceptor (betaAR) antagonist propranolol. During application of betaAR agonists repeated stimulation resulted in facilitated induction of SPW-Rs. Since SPW-Rs are thought to be involved in memory replay we studied the effects of betaAR-agonists on spontaneous SPW-Rs in murine hippocampus and found that amplitude and incidence of SPW-Rs increased. These effects involve cyclic-AMP and the activation of protein kinase A and suggest a supportive role in memory consolidation. (c) 2016 Wiley Periodicals, Inc. PMID- 27699901 TI - Model of the delayed translation of cyclin B maternal mRNA after sea urchin fertilization. AB - Sea urchin eggs exhibit a cap-dependent increase in protein synthesis within minutes after fertilization. This rise in protein synthesis occurs at a constant rate for a great number of proteins translated from the different available mRNAs. Surprisingly, we found that cyclin B, a major cell-cycle regulator, follows a synthesis pattern that is distinct from the global protein population, so we developed a mathematical model to analyze this dissimilarity in biosynthesis kinetic patterns. The model includes two pathways for cyclin B mRNA entry into the translational machinery: one from immediately available mRNA (mRNAcyclinB) and one from mRNA activated solely after fertilization (XXmRNAcyclinB). Two coefficients, alpha and beta, were added to fit the measured scales of global protein and cyclin B synthesis, respectively. The model was simplified to identify the synthesis parameters and to allow its simulation. The calculated parameters for activation of the specific cyclin B synthesis pathway after fertilization included a kinetic constant (ka ) of 0.024 sec-1 , for the activation of XXmRNAcyclinB, and a critical time interval (t2 ) of 42 min. The proportion of XXmRNAcyclinB form was also calculated to be largely dominant over the mRNAcyclinB form. Regulation of cyclin B biosynthesis is an example of a select protein whose translation is controlled by pathways that are distinct from housekeeping proteins, even though both involve the same cap-dependent initiation pathway. Therefore, this model should help provide insight to the signaling utilized for the biosynthesis of cyclin B and other select proteins. Mol. Reprod. Dev. 83: 1070-1082, 2016.

AB - The design of artificial systems that mimic highly evolved and finely tuned natural enzymes is a promising subject of intensive research. The assembly of O symmetric cubic structures with an Fe8 L6 formula was reported through the direct combination of a C4 -symmetric tetraphenylethylene-based ligand with a C3 symmetric tris(bipyridine)iron node. The robust metal-organic cubes are rich in pi-electron density and provide favorable interactions with planar polycyclic aromatic hydrocarbons. Within the confined space of the host, the aromatic hydrocarbons molecules are forced closer to the redox active host, and the photoinduced electron transfer (PET) is modified into a pseudo-intramolecular pathway. These iron vertices within the cubes exhibit suitable redox potential for electrochemical reduction of protons and the well-modified PET is further tailored to create artificial systems for light-driven hydrogen evolution from water through the encapsulation of fluorescein dyes. Control experiments based on a mononuclear compound resembling the iron corner of the octahedron suggest an enzymatic dynamic behavior. The new, well-elucidated reaction pathways and the increased molarity of the reaction within the confined space render these supramolecular systems superior to other relevant systems.

AB - BACKGROUND: Cancer-associated fibroblasts (CAFs) were shown to be important for tumour progression in head and neck squamous cell carcinomas (HNSCCs). Their heterogeneity and lack of specific markers is increasingly recognized. Integrin alpha11 was recently shown to be expressed by CAFs and might serve as a specific CAF marker. AIM: To investigate integrin alpha11 expression and its correlation with the expression of a well-known marker of CAF, alpha smooth muscle actin (alpha-SMA), in HNSCC. METHODS: Fresh frozen (FF) and formalin-fixed paraffin embedded (FFPE) samples from healthy volunteers (n = 24), oral lichen planus (OLP) (n = 32) and HNSCC (n = 106) were collected together with clinical data after ethical approval. Immunohistochemistry to detect integrin alpha11 and alpha SMA was performed on FF and FFPE samples. qPCR for integrin alpha11 (ITGA11) and alpha-SMA (ACTA2) was performed on FF samples. Data were analysed using chi square test and Kaplan-Meier survival analysis. RESULTS: Significantly higher levels of integrin alpha11 and alpha-SMA at both protein and mRNA levels were found in HNSCC vs. normal controls and OLP. A strong correlation was found between integrin alpha11 and alpha-SMA expression, and double staining showed their colocalization. Both integrin alpha11 and alpha-SMA were detected surrounding metastatic islands. Expression of alpha-SMA at tumour front but not tumour centre correlated with patient survival. CONCLUSION: Integrin alpha11 was overexpressed in HNSCC stroma and colocalized with alpha-SMA. Expression of alpha SMA at tumour front but not tumour centre had prognostic value for survival, pinpointing the importance of assessing tumour front when evaluating stromal molecules as prognostic biomarkers. PMID- 27699904 TI - Rational Control of Conformational Distributions and Mixed-Valence Characteristics in Diruthenium Complexes. AB - The electronic characteristics of mixed-valence complexes are often inferred from the shape of the inter-valence charge transfer (IVCT) band, which usually falls in the near infrared (NIR) region, and relationships derived from Marcus-Hush theory. These analyses typically assume one single, dominant molecular conformation. The NIR spectra of the prototypical delocalised (Class III Robin Day mixed-valence) complexes [{Ru(pp)Cp'}2 (MU-C=C-C=C)]+ ([1]+ : Cp'=Cp, pp=(PPh3 )2 ; [2]+ : Cp'=Cp, pp=dppe; [3]+ : Cp'=Cp*, pp=dppe) feature a 'two band' pattern, which complicates band-shape analysis using these traditional methods. In the past, the appearance of sub-bands within or near the IVCT transition has been attributed to vibronic effects or localised d-d transitions. Quantum-chemical modelling of a series of rotational conformers of [1]+ -[3]+ reveals the two components that contribute to the NIR absorption band envelope to be a pi-pi* transition and an MLCT transition. The MLCT components only gain appreciable intensity when the orientation of the half-sandwich ruthenium ligand spheres deviates from idealised cis (Omega P-Ru-Ru-P=0 degrees ) or trans (Omega P-Ru-Ru-P=180 degrees ) conformations. The increased steric demand of the supporting ligands, together with some underlying inter-phosphine ligand T-shaped CH???pi stacking interactions across the series [1]+ to [2]+ to [3]+ results in local minima biased towards such non-idealised conformations of the metal-ligand fragments (Omega P-Ru-Ru-P=33-153 degrees ). Experimentally, this is indicated by appearance of multiple bands within the IR nu~ (C=C) band envelopes and increasing intensity of the higher-energy MLCT transition(s) relative to the pi pi* transition across the series, and the appearance of a pronounced 'two-band' pattern in the experimental NIR absorption envelopes. These conformational effects and the methods of analysis presented here, which combine analysis of IR and NIR spectra with quantum-chemical calculations on a range of energetically similar conformational minima, are expected to be quite general for mixed-valence systems.

AB - Shikimate kinase (SK), the fifth enzyme of the aromatic amino acid biosynthesis, is a recognized target for antibiotic drug discovery. The potential of the distinct dynamic apolar gap, which isolates the natural substrate from the solvent environment for catalysis, and the motion of Mycobacterium tuberculosis and Helicobacter pylori SK enzymes, which was observed by molecular dynamics simulations, was explored for inhibition selectivity. The results of the biochemical and computational studies reveal that the incorporation of bulky groups at position C5 of 5-aminoshikimic acid and the natural substrate enhances the selectivity for the H. pylori enzyme due to key motion differences in the shikimic acid binding domain (mainly helix alpha5). These studies show that the less-exploited motion-based design approach not only is an alternative strategy for the development of competitive inhibitors, but could also be a way to achieve selectivity against a particular enzyme among its homologues.

AB - A straightforward and transition-metal-free approach for the efficient synthesis of alpha-arylglycine derivatives from aromatic imines and carbon dioxide was enabled by an umpolung carboxylation reaction. Various substituted diphenylmethimines underwent the carboxylation smoothly with carbon dioxide in the presence of potassium tert-butoxide and 18-crown-6 to give the corresponding carboxylated products in good to high yields. Besides the enhancement of the solubility of potassium tert-butoxide in THF, 18-crown-6 also plays key roles in suppressing the reverse protonation or 1, 3-proton shift isomerization as well as by stabilizing the carboxylated intermediate. PMID- 27699906 TI - Stable isotope analyses of oxygen (18 O:17 O:16 O) and chlorine (37 Cl:35 Cl) in perchlorate: reference materials, calibrations, methods, and interferences. AB - RATIONALE: Perchlorate (ClO4- ) is a common trace constituent of water, soils, and plants; it has both natural and synthetic sources and is subject to biodegradation. The stable isotope ratios of Cl and O provide three independent quantities for ClO4- source attribution and natural attenuation studies: delta37 Cl, delta18 O, and delta17 O (or Delta17 O or 17 Delta) values. Documented reference materials, calibration schemes, methods, and interferences will improve the reliability of such studies. METHODS: Three large batches of KClO4 with contrasting isotopic compositions were synthesized and analyzed against VSMOW SLAP, atmospheric O2 , and international nitrate and chloride reference materials. Three analytical methods were tested for O isotopes: conversion of ClO4- to CO for continuous-flow IRMS (CO-CFIRMS), decomposition to O2 for dual inlet IRMS (O2-DIIRMS), and decomposition to O2 with molecular-sieve trap (O2 DIIRMS+T). For Cl isotopes, KCl produced by thermal decomposition of KClO4 was reprecipitated as AgCl and converted into CH3 Cl for DIIRMS. RESULTS: KClO4 isotopic reference materials (USGS37, USGS38, USGS39) represent a wide range of Cl and O isotopic compositions, including non-mass-dependent O isotopic variation. Isotopic fractionation and exchange can affect O isotope analyses of ClO4- depending on the decomposition method. Routine analyses can be adjusted for such effects by normalization, using reference materials prepared and analyzed as samples. Analytical errors caused by SO42- , NO3- , ReO42- , and C-bearing contaminants include isotope mixing and fractionation effects on CO and O2 , plus direct interference from CO2 in the mass spectrometer. The results highlight the importance of effective purification of ClO4- from environmental samples. CONCLUSIONS: KClO4 reference materials are available for testing methods and calibrating isotopic data for ClO4- and other substances with widely varying Cl or O isotopic compositions. Current ClO4- extraction, purification, and analysis techniques provide relative isotope-ratio measurements with uncertainties much smaller than the range of values in environmental ClO4- , permitting isotopic evaluation of environmental ClO4- sources and natural attenuation.

AB - BACKGROUND: Oncologists must communicate effectively with patients and their families about end of life (EOL). Despite the importance of communicating on this topic, many oncologists avoid these conversations. The objective of this study was to examine the associations between secondary traumatic stress and compassion satisfaction and approach and avoidant communication about EOL with cancer patients. METHODS: A convenience sample of 79 oncologists (n = 27 men, n = 52 women) participated in the study. Oncologists completed a survey that included a sociodemographic and clinical information questionnaire, the Professional Quality of Life Scale, and Communication about End of Life Survey. To examine the effect of secondary traumatic stress and compassion satisfaction on approach and avoidant communication, while controlling for gender and age, 2 hierarchical linear regression analyses were computed. RESULTS: Oncologists reported high levels of secondary traumatic stress and high compassion satisfaction. Scores on the approach and avoidant communication scales were in the mid-range of the scale. Lower reports of secondary traumatic stress and higher compassion satisfaction were associated with higher approach communication strategies: however, only higher secondary traumatic stress was associated with higher avoidant communication strategies. CONCLUSIONS: Our findings indicate that there is an association between emotional factors and approach communication. The findings have clinical implications in designing effective communication skills training. Further research and training should take secondary traumatic stress and compassion satisfaction into consideration to be able to ensure that terminal patients and their families receive the best quality EOL care.

AB - RATIONALE: The aim of the study was to use a technique that combines acid hydrolysis and matrix-assisted laser desorption ionization/time-of-flight mass spectrometry (MALDI-TOF MS) in order to detect the serum biomarkers of patients diagnosed with schizophrenia both before and after four-week antipsychotic treatment with risperidone. METHODS: During this study's two-year period, inpatients were diagnosed with schizophrenia using the Structured Clinical Interview for DSM-IV Axis I Disorders. Severity was then evaluated using the Positive and Negative Syndrome Scale both at baseline and at endpoint following four-week treatment with risperidone. The patients' serum biomarkers were quickly measured using acid hydrolysis and MALDI-TOF MS. The resulting peptides were then analyzed using MALDI-TOF MS. We constructed a receiver operating characteristic (ROC) curve for the evaluated biomarkers. RESULTS: We recruited 20 pairs of participants for this study. The experimental group was treated with serum protein with HCl for 10 minutes to effectively hydrolyze abundant proteins. The target peptide, the immunoglobulin gamma chain (IgG), was then rapidly detected using this manner. A significant difference was found in the IgG levels of patients with schizophrenia before and after antipsychotic treatment. We constructed a ROC curve based on the IgG, and the area under said curve was 0.969. In comparison to conventional detection protocols, this method takes only minutes to complete and is also less costly. CONCLUSIONS: This study found that applying acid hydrolysis with MALDI-TOF MS technology could rapidly differentiate serum IgG levels in patients with schizophrenia before and after being treated with risperidone. This IgG difference may enhance the understanding of mechanism of antipsychotic treatment of schizophrenia. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27699910 TI - POSITRON EMISSION TOMOGRAPHY OF THE EQUINE DISTAL LIMB: EXPLORATORY STUDY. AB - Positron emission tomography (PET) is a highly sensitive, noninvasive imaging technique for quantifying biological functions of tissues. However, at the time of this study, PET imaging applications had not been reported in the horse. The aim of this exploratory study was to determine whether a portable high-resolution PET scanner could be used to image the equine distal limb. Images of the front feet and fetlocks of three research horses, with known lesions localized to the distal front limbs, were acquired under general anesthesia after administration of 18 F-fluorodeoxyglucose (18 F-FDG), with doses ranging from 1.5 to 2.9 MBq/kg. The radiation exposure measured during imaging was slightly higher than 99m Technetium scintigraphy. However, the use of general anesthesia allowed the proximity and the contact time with the patient to be minimized for the staff involved. 18 F-FDG uptake was evident throughout the soft tissues, with the highest uptake in the coronary band and the lowest uptake in the tendons. Anatomic structures could be discriminated due to the high contrast between soft tissue and bone. Detected lesions included lysis of the flexor cortex of the navicular bone, lesions of flexor tendons and suspensory ligament, and abnormal uptake through the lamina of a laminitic subject. Findings indicated that tomographic molecular imaging is feasible in the equine distal limb and could be useful as a future diagnostic technique for clinical and research studies, especially those involving tendinopathy/desmopathy and laminitis. PMID- 27699911 TI - Individual prediction of long-term outcome in adolescents at ultra-high risk for psychosis: Applying machine learning techniques to brain imaging data. AB - An important focus of studies of individuals at ultra-high risk (UHR) for psychosis has been to identify biomarkers to predict which individuals will transition to psychosis. However, the majority of individuals will prove to be resilient and go on to experience remission of their symptoms and function well. The aim of this study was to investigate the possibility of using structural MRI measures collected in UHR adolescents at baseline to quantitatively predict their long-term clinical outcome and level of functioning. We included 64 UHR individuals and 62 typically developing adolescents (12-18 years old at recruitment). At six-year follow-up, we determined resilience for 43 UHR individuals. Support Vector Regression analyses were performed to predict long term functional and clinical outcome from baseline MRI measures on a continuous scale, instead of the more typical binary classification. This led to predictive correlations of baseline MR measures with level of functioning, and negative and disorganization symptoms. The highest correlation (r = 0.42) was found between baseline subcortical volumes and long-term level of functioning. In conclusion, our results show that structural MRI data can be used to quantitatively predict long-term functional and clinical outcome in UHR individuals with medium effect size, suggesting that there may be scope for predicting outcome at the individual level. Moreover, we recommend classifying individual outcome on a continuous scale, enabling the assessment of different functional and clinical scales separately without the need to set a threshold.

AB - The purpose of this study was to evaluate the effect of 2.5 degrees C cold saline irrigation as final irrigant on postoperative pain after single-visit root canal treatment of teeth with vital pulps. One-hundred and seventy patients were assessed as eligible and included to the study. The teeth were randomly divided into two groups (n = 85) (i.e. the control group and the cryotherapy group). In the cryotherapy group, final irrigation with 2.5 degrees C 0.9% physiological saline solution for 5 min was performed following completion of biomechanical preparation, whereas in control group same solution stored at the root temperature was used. Treatments were performed in a single visit. Participants were asked to rate the intensity of their postoperative pain using visual analogue scale at 24 and 48 h. Data were analysed by Mann-Whitney U test and Student's t test. In the cryotherapy group level of reported postoperative pain was significantly lower than the control group (P < 0.05, Mann-Whitney U test). The outcome of this investigation indicates that 2.5 degrees C cold saline irrigation as final irrigant can result a significant reduction in postoperative pain levels in comparison to the control group. Cryotherapy is a simple, cost effective, and non-toxic option for postoperative pain control in single visit root canal treatment. PMID- 27699912 TI - PROTECTED-UK - Clinical pharmacist interventions in the UK critical care unit: exploration of relationship between intervention, service characteristics and experience level. AB - PURPOSE: Clinical pharmacist (CP) interventions from the PROTECTED-UK cohort, a multi-site critical care interventions study, were further analysed to assess effects of: time on critical care, number of interventions, CP expertise and days of week, on impact of intervention and ultimately contribution to patient care. METHODS: Intervention data were collected from 21 adult critical care units over 14 days. Interventions could be error, optimisation or consults, and were blind coded to ensure consistency, prior to bivariate analysis. Pharmacy service demographics were further collated by investigator survey. KEY FINDINGS: Of the 20 758 prescriptions reviewed, 3375 interventions were made (intervention rate 16.1%). CPs spent 3.5 h per day (mean, +/-SD 1.7) on direct patient care, reviewed 10.3 patients per day (+/-SD 4.2) and required 22.5 min (+/-SD 9.5) per review. Intervention rate had a moderate inverse correlation with the time the pharmacist spent on critical care (P = 0.05; r = 0.4). Optimisation rate had a strong inverse association with total number of prescriptions reviewed per day (P = 0.001; r = 0.7). A consultant CP had a moderate inverse correlation with number of errors identified (P = 0.008; r = 0.6). No correlation existed between the presence of electronic prescribing in critical care and any intervention rate. Few centres provided weekend services, although the intervention rate was significantly higher on weekends than weekdays. CONCLUSIONS: A CP is essential for safe and optimised patient medication therapy; an extended and developed pharmacy service is expected to reduce errors. CP services should be adequately staffed to enable adequate time for prescription review and maximal therapy optimisation. PMID- 27699914 TI - Oxime ligation in acetic acid: efficient synthesis of aminooxy-peptide conjugates. AB - Oxime ligation is a powerful tool in various bioconjugation strategies. Nevertheless, high reaction rates and quantitative yields are typically reported for aldehyde-derived compounds. In contrary, keto groups react much slower, with quantitative yields achieved at 5 h for low-molecular weight compounds and more than 15 h for polymers or dendrimers. In this communication, we report that oxime ligation proceeds rapidly with quantitative (>95%) conversion within 1.5-2 h in pure acetic acid. The practical utility of suggested technique is illustrated by the synthesis of peptide-steroid and peptide-polymer conjugates of model aminooxy peptides.

PMID- 27699915 TI - Relationship between physical performance and quality of life in Charcot-Marie Tooth disease: a pilot study. AB - Charcot-Marie-Tooth (CMT) is a rare inherited peripheral neuropathy in which quality of life (QoL) is reduced compared with the general population. This paper investigates the relationship between QoL and physical performance in people with CMT with the aim of identifying avenues for future research into rehabilitation strategies. Cross-sectional data was obtained from 10 participants (5 men, 5 women, age 46 +/- 13 years, height 1.7 +/- 0.1 m, body mass 77 +/- 17 kg) with CMT (CMT1A n = 5; CMT-X n = 3; unknown genetic origin n = 2). Participants were evaluated for QoL, falls efficacy (FES), balance, mobility, muscle strength, and power. Physical component score (PCS) of the Short Form-36 (SF-36) was significantly and directly related to higher leg press power (r = 0.75, p = 0.02). Better FES scores were significantly related to faster habitual gait speed (r = -0.70, p = 0.02), left hip abduction, and seated row strength (r = -0.68, p = 0.03; r = -0.73, p = 0.03, respectively). Future research should aim to substantiate these preliminary findings in a larger cohort and investigate whether interventions targeting muscle strength and power can improve QoL and mobility outcomes in people with CMT. PMID- 27699917 TI - Bulk delta15 N measurements of organic-rich rock samples by elemental analyzer/isotope ratio mass spectrometry with enhanced oxidation ability. AB - RATIONALE: Elemental analyzer/isotope ratio mass spectrometry (EA/IRMS) has been widely used for nitrogen isotope ratio determination in various organic and inorganic samples. However, the extent of the redox reaction in the EA reaction tube can greatly affect the accuracy and precision of measurements, especially in the case of complex geological samples. It is therefore necessary to determine the appropriate reaction conditions to reach a high recovery of nitrogen by complete combustion or thermal decomposition and quantitative reduction. METHODS: The conventional Dumas dual-inlet method was used to determine the bulk nitrogen isotope composition of SGR-1 (an organic-rich standard sample), which then was analyzed by EA/IRMS under different EA reaction conditions to study the influence of the redox environment on the delta15 N measurements. The measured data together with the results reported by previous researchers were used to evaluate the effectiveness of the nitrogen extraction for organic-rich rock samples. RESULTS: Our results demonstrated that with the Dumas dual-inlet method more oxidizing agent (CuO) addition to SGR-1 would yield a higher nitrogen content of 0.91% than the recommended content (0.81%) although a delta15 N value of 17.39 +/ 0.090/00 was consistent with the recommended value by USGS. Using EA/IRMS, when more O2 was injected in the reaction tube, a high nitrogen content (0.92 +/- 0.01%) and a delta15 N value (17.43 +/- 0.170/00) close to that of the Dumas dual inlet method were obtained. The addition of V2 O5 or CuO in a continuous-flow system of EA/IRMS could not effectively enable the complete combustion of SGR-1. CONCLUSIONS: When measuring the nitrogen isotope composition of organic-rich rock sample dominated by reduced substances with EA/IRMS, greater O2 injection will enable more complete combustion to obtain reliable nitrogen yields compared with the addition of V2 O5 or CuO.

AB - Myosin light chain kinase (MLCK) is a key regulator of various forms of cell motility including smooth muscle contraction, cell migration, cytokinesis, receptor capping, secretion, etc. Inhibition of MLCK activity in endothelial and epithelial monolayers using cell-permeant peptide Arg-Lys-Lys-Tyr-Lys-Tyr-Arg-Arg Lys (PIK, Peptide Inhibitor of Kinase) allows protecting the barrier capacity, suggesting a potential medical use of PIK. However, low stability of L-PIK in a biological milieu prompts for development of more stable L-PIK analogues for use as experimental tools in basic and drug-oriented biomedical research. Previously, we designed PIK1, H-(Nalpha Me)Arg-Lys-Lys-Tyr-Lys-Tyr-Arg-Arg-Lys-NH2 , that was 2.5-fold more resistant to peptidases in human plasma in vitro than L-PIK and equal to it as MLCK inhibitor. In order to further enhance proteolytic stability of PIK inhibitor, we designed the set of six site-protected peptides based on L PIK and PIK1 degradation patterns in human plasma as revealed by 1 H-NMR analysis. Implemented modifications increased half-live of the PIK-related peptides in plasma about 10-fold, and these compounds retained 25-100% of L-PIK inhibitory activity toward MLCK in vitro. Based on stability and functional activity ranking, PIK2, H-(Nalpha Me)Arg-Lys-Lys-Tyr-Lys-Tyr-Arg-D-Arg-Lys-NH2 , was identified as the most stable and effective L-PIK analogue. PIK2 was able to decrease myosin light chain phosphorylation in endothelial cells stimulated with thrombin, and this effect correlated with the inhibition by PIK2 of thrombin induced endothelial hyperpermeability in vitro. Therefore, PIK2 could be used as novel alternative to other cell-permeant inhibitors of MLCK in cell culture-based and in vivo studies where MLCK catalytic activity inhibition is required.

AB - Anticancer drug discovery efforts have used 2-D cell-based assay models, which fail to forecast in vivo efficacy and result in a lower success rate of clinical approval. Recent 3-D cell culture models are expected to bridge the gap between 2 D and in vivo models. However, 3-D cell culture methods that are available for practical anticancer drug screening have not yet been fully attained. In this study, we screened several polymers for their ability to suspend cells or cell spheroids homogeneously in a liquid medium without changing the viscosity behavior, and identified gellan gum (FP001), as the most potent polymer. FP001 promoted cell dispersion in the medium and improved the proliferation of a wide range of cancer cell lines under low attachment conditions by inhibiting the formation of large-sized spheroids. In addition, cancer cells cultured with FP001 containing medium were more susceptible to inhibitors of epidermal growth factor (EGF) signaling than those cultured under attachment conditions. We also showed that ligands of the EGF receptor family clearly enhance proliferation of SKOV3 ovarian carcinoma cells under anchorage-independent conditions with FP001. Consistent with this result, the cells grown with FP001 showed higher EGF receptor content compared with cells cultured under attachment conditions. In conclusion, we developed a novel 3-D cell culture system that is available for high throughput screening of anticancer agents, and is suitable for evaluation of molecular-targeted anticancer drugs. Three-dimensional cell culture using FP001 will be of value in the development of useful technologies for anticancer drug discovery. PMID- 27699919 TI - Obstructive sleep apnoea pathogenesis from mild to severe: Is it all the same? AB - Obstructive sleep apnoea (OSA) is a common disorder caused by not only an impaired upper airway anatomy (i.e. anatomically narrow/collapsible airway), but also by several non-anatomical factors. In this review, we summarise what is known about how each of the pathological factors that cause OSA vary according to disease severity as measured by the apnoea-hypopnoea index. Our synthesis of the available literature indicates that most of the key factors that cause OSA vary with disease severity. However, there is substantial heterogeneity such that the relative contribution of each of these traits varies both between patients and within different severities of disease. These differences likely contribute to variable efficacy of many non-continuous positive airway pressure treatments and inconsistencies in responses with regard to different OSA severities at baseline. PMID- 27699920 TI - Change Factors in the Process of Cognitive-Behavioural Therapy for Obsessive Compulsive Disorder. AB - : While there is a plethora of evidence for the efficacy of cognitive-behavioural therapy (CBT) in obsessive-compulsive disorder (OCD), studies on change factors of the therapeutic process that account for this success are scarce. In the present study, 155 participants with primary OCD were investigated during CBT inpatient treatment. The Yale-Brown Obsessive-Compulsive Scale-SR served as a measure of symptom severity. In addition, the following process change factors were measured: therapeutic relationship, experience of self-esteem during therapy, experience of mastery, problem actualization and clarification. All variables were assessed on a weekly basis for seven weeks. Linear mixed growth curve analyses were conducted to model the decrease of symptoms over time and to analyse whether the change factors predicted symptom reduction. The analyses revealed a linear decrease of symptoms with high inter-individual variation. Results further showed that increase in self-esteem and mastery experiences as well as the initial score on mastery experience and clarification predicted decrease on the Y-BOCS. We conclude that CBT therapists should focus on clarification in the very first sessions, and try to boost self-esteem and self efficacy, which is related to mastery, throughout the treatment of OCD. Copyright (c) 2016 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Increase in mastery and self-esteem experiences are associated with symptom decrease in obsessive compulsive disorder (OCD) during cognitive-behavioural therapy (CBT). Initial score of mastery experiences and problem clarification predict symptom decrease in OCD during CBT. CBT therapists should focus on problem clarification in the very first sessions and try to boost self-esteem and self-efficacy throughout the treatment of OCD. PMID- 27699921 TI - COMPUTED TOMOGRAPHIC FINDINGS IN CANINE ELBOWS ARTHROSCOPICALLY DIAGNOSED WITH EROSION OF THE MEDIAL COMPARTMENT: AN ANALYTICAL METHOD COMPARISON STUDY. AB - Medial compartment erosion is an advanced stage of medial coronoid disease, an important cause of elbow lameness in dogs, with treatment and the expected prognosis depending on the extent of the cartilage lesions. The identification of specific computed tomographic (CT) findings might facilitate the nonsurgical diagnosis and add to treatment decision making. Aims of this retrospective, analytical, method comparison study were to describe CT findings in elbows of dogs arthroscopically diagnosed with medial compartment erosion and to compare CT vs. arthroscopic findings. A total of 56 elbows met inclusion criteria. Elbows with focal (n = 13), diffuse (n = 11), and complete (n = 32) erosion were compared. Prevalence findings for CT lesions were as follows: periarticular osteophytosis (100%), abnormal shape of the medial coronoid process of the ulna (96.4%), and subchondral bone defect of the medial part of the humeral condyle (MHC; 96.4%). The three groups significantly differed for presence of medial coronoid process fragmentation, radial head subchondral bone sclerosis, and widening of the humeroulnar joint space. No significant agreement was found between CT and arthroscopy for presence of a subchondral bone defect of the MHC. A significant agreement was found between CT and arthroscopy for presence of fragmentation of the medial coronoid process. However, some of the calcified body/fragment(s) visualized on CT in the region of the medial coronoid process could not be identified via arthroscopy. Findings indicated that an accurate estimation of the extent of the elbow cartilage lesions still requires arthroscopic joint inspection. PMID- 27699922 TI - Intravenous iron and erythropoiesis-stimulating agents in haemodialysis: A systematic review and meta-analysis. AB - AIM: Higher dosages of erythropoiesis-stimulating agents (ESAs) have been associated with adverse effects. Intravenous iron is used to optimize ESA response and reduces ESA doses in haemodialysis patients; this meta-analysis evaluates the magnitude of this effect. METHODS: A literature search was performed using MEDLINE, Embase and the Cochrane Collaboration Central Register of Clinical Trials from inception until December 2014, to identify randomized controlled trials of intravenous iron and ESA, in patients undergoing haemodialysis for end-stage kidney disease. Dosing of IV iron in concordance with the Kidney Disease Improving Global Outcomes guidelines was considered optimal iron therapy. RESULTS: Of the 28 randomized controlled trials identified, seven met the criteria for inclusion in the meta-analysis. Results of random-effects meta-analysis show a statistically significant weighted mean (95% CI) difference of -1733 [-3073, -392] units/week in ESA dose for optimal iron versus suboptimal iron. The weighted average change in ESA dose was a reduction of 23% (range -7% to -55%) attributable to appropriate dosing of intravenous iron. A comparison of intravenous iron versus oral iron/no iron (five trials) showed a greater reduction in ESA dose, although this did not reach statistical significance (weighted mean difference, 95% CI: -2,433 [-5183, 318] units/week). The weighted average change in ESA dose across the five trials was a reduction of 31% (range 8% to -55%). CONCLUSION: Significant reductions in ESA dosing may be achieved with optimal intravenous iron usage in the haemodialysis population, and suboptimal iron use may require higher ESA dosing to manage anaemia. PMID- 27699923 TI - Age-related cognitive decline coincides with accelerated volume loss of the dorsal but not ventral hippocampus in mice. AB - Even in the absence of neurodegenerative diseases, progressing age often coincides with cognitive decline and morphological changes. However, longitudinal studies that directly link these two processes are missing. In this proof-of concept study we therefore performed repeated within-subject testing of healthy male R26R mice in a spatial learning task in combination with manganese-enhanced volumetric MRI analyses at the ages of 8, 16, and 24 months. We grouped the mice into good and poor performers (n = 6, each), based on their spatial learning abilities at the age of 24 months. Using this stratification, we failed to detect a priori volume differences, but observed a significant decrease in total hippocampal volume over time for both groups. Interestingly, this volume decrease was specific for the dorsal hippocampus and significantly accelerated in poor performers between 16 and 24 months of age. This is the first time that individual changes in hippocampal volume were traced alongside cognitive performance within the same subjects over 11/2 years. Our study points to a causal link between volume loss of the dorsal hippocampus and cognitive impairments. In addition, it suggests accelerated degenerative processes rather than a priori volume differences as determining trajectories of age-related cognitive decline. Despite the relatively small sample sizes, the strong behavioral and moderate morphological alterations demonstrate the general feasibility of longitudinal studies of age-related decline in cognition and hippocampus integrity.

AB - Non-volatile solutes in an evaporating drop experience an out-of-equilibrium state due to non-linear concentration effects and complex flow patterns. Here, we demonstrate a small molecule chemical reaction network that undergoes a rapid adaptation response to the out-of-equilibrium conditions inside the droplet leading to control over the molecular constitution and spatial arrangement of the deposition pattern. Adaptation results in a pronounced coffee stain effect and coupling to chemical concentration gradients within the drop is demonstrated. Amplification and suppression of network species are readily identifiable with confocal fluorescence microscopy. We anticipate that these observations will contribute to the design and exploration of out-of-equilibrium chemical systems, as well as be useful towards the development of point-of-care medical diagnostics and controlled deposition of small molecules through inkjet printing. PMID- 27699929 TI - Bovine endometrial cells: a source of mesenchymal stem/progenitor cells. AB - Endometrial mesenchymal stem/progenitor cells (eMSCs) are multipotent cells known to modulate the immune system and have clinical application for human and animal health. This makes these bovines cells attractive for dual use as cellular therapy and experimental model. The aim of this study was to isolate, evaluate the differentiation potential, immunophenotypic and immunocytochemistry characteristics, chromosomal stability, cloning efficiency, and cryopreservation response of bovine eMSCs collected in two phases of the estrous cycle. For this, cells were isolated and submitted to differentiation for adipogenic and osteogenic lineage. The cells were then characterized by flow cytometer (FC) (vimentin, CD29, CD44, MHC-II, CD34) and immunocytochemistry (vimentin, pan cytokeratin, CD44) and submitted to cytogenetic and cloning efficiency assay. The cells were also cryopreserved using two different medium of cryopreservation and analyzed by FC for viability, necrosis, late-apoptosis + necrosis, and initial apoptosis rates before and after cryopreservation. We obtained homogeneous cell populations which have fibroblastic morphology and adherence to plastic. These cells expressed high levels of markers CD29, CD44, and vimentin, low expression levels for CD34 and no MHC-II. The cells were chromosomally stable (2n = 60) with high cloning efficiency and no difference (P > 0.05) between medium of cryopreservation or phase was observed after thawing. We showed the presence and differentiation potential of bovine eMSCs, with chromosomal stability and great response to cryopreservation with both medium, which has implications for build biobanks or development of new therapeutic approaches to combat uterine diseases or to study.

AB - BACKGROUND AND PURPOSE: Brain atrophy is related to clinical deterioration in multiple sclerosis (MS) but its association with intrathecal markers of inflammation or neurodegeneration is unclear. Our aim was to investigate whether cerebrospinal fluid (CSF) markers of inflammation or neurodegeneration are associated with brain volume change in natalizumab-treated MS and whether this change is reflected in non-lesional white matter metabolites. METHODS: About 25 patients with natalizumab-treated MS were followed for 3 years with assessment of percentage brain volume change (PBVC) and absolute quantification of metabolites with proton magnetic resonance spectroscopy (1 H MRS). Analyses of inflammatory [interleukin 1beta (IL-1beta), IL-6, C-X-C motif chemokine 8 (CXCL8), CXCL10, CXCL11, C-C motif chemokine 22] and neurodegenerative [neurofilament light protein (NFL), glial fibrillary acidic protein, myelin basic protein, tau proteins] markers were done at baseline and 1-year follow-up. RESULTS: The mean decline in PBVC was 3% at the 3-year follow-up, although mean 1 H MRS metabolite levels in non-lesional white matter were unchanged. CSF levels of NFL and tau at baseline correlated negatively with PBVC over 3 years (r = -0.564, P = 0.012, and r = -0.592, P = 0.010, respectively). CONCLUSIONS: A significant 3-year whole brain atrophy was not reflected in mean metabolite change of non-lesional white matter. In addition, our results suggest that CSF levels of NFL and tau correlate with brain atrophy development and may be used for evaluating treatment response in inflammatory active MS.

AB - OBJECTIVE: The New Zealand Ministry of Health responded to community concern about dioxin exposure during on-site remediation of a pesticide-contaminated rural area by commissioning this exposed-referent study of serum dioxins and health in local residents. METHODS: All 200 residents were eligible, with age and sex matching to demographically comparable referents. Face-to-face interviews included questions on health status, health-related quality of life (HRQOL) and perceptions about community consultation. Thirty serum samples were obtained, eligibility being based on likelihood of exposure and age. Both HRQOL and serum outcomes were analysed by the appropriate regression methods. RESULTS: Of 200 eligible residents, 139 (69.5%) participated, with 139 matched referents. Mapua residents had lower physical and psychological HRQOL scores, but no difference in health status. 2,3,7,8 TCDD was below the limit of detection in the majority of all serum samples, with some congeners being higher in referents. Perceptions of the communication process were equivocal. CONCLUSIONS: Both dioxin levels and measures of health did not differ significantly between the exposed community and controls. Implications for public health: The results suggest neither significant dioxin exposure nor community health effects. Oversight by expert panel with health expertise, allied to sound communication, may have helped the community understand the risks. PMID- 27699934 TI - Lymphocyte-depleting induction therapy lowers the risk of acute rejection in African American pediatric kidney transplant recipients. AB - The use of lymphocyte-depleting induction immunosuppression has been associated with a reduction in risk of AR after KT among adult recipients, particularly among high-risk subgroups such as AAs. However, data on induction regimen and AR risk are lacking among pediatric KT recipients. We examined outcomes among 7884 first-time pediatric KT recipients using SRTR data (2000-2014). Characteristics were compared across race using Wilcoxon rank-sum tests for continuous and chi square tests for categorical variables. Risk of AR was estimated using modified Poisson regression, stratified by recipient race, adjusting for recipient age, gender, BMI, primary diagnosis, number of HLA mismatches, maintenance immunosuppression, and donor type. Risk of AR within 1 year was lower in AA recipients receiving lymphocyte-depleting induction (ATG or alemtuzumab; RR, 0.66; 95% CI, 0.52-0.83 P < .001) compared to AA recipients receiving anti-IL-2 receptor antibody induction. This difference was not seen in non-AA recipients receiving lymphocyte-depleting induction (RR, 0.93; 95% CI, 0.81-1.06, P = .26) compared to IL-2 induction. These findings support a role for lymphocyte depleting induction agents in AA pediatric patients undergoing KT and continued use of IL-2 inhibitor induction in non-AA pediatric KT recipients. PMID- 27699935 TI - Transplantation of organs from deceased donors with meningitis and encephalitis: a UK registry analysis. AB - BACKGROUND: Deceased organ donors, where the cause of death is meningitis or encephalitis, are a potential concern because of the risks of transmission of a potentially fatal infection to recipients. METHODS: Using the UK Transplant Registry, a retrospective cohort analysis of deceased organ donors in the UK was undertaken to better understand the extent to which organs from deceased donors with meningitis and/or encephalitis (M/E) (of both known and unknown cause) have been used for transplantation, and to determine the associated recipient outcomes. RESULTS: Between 2003 and 2015, 258 deceased donors with M/E were identified and the causative agent was known in 188 (72.9%). These donors provided 899 solid organs for transplantation (455 kidneys and 444 other organs). The only recorded case of disease transmission was from a donor with encephalitis of unknown cause at time of transplantation who transmitted a fatal nematode infection to 2 kidney transplant recipients. A further 3 patients (2 liver and 1 heart recipient) died within 30 days of transplantation from a neurological cause (cerebrovascular accident) with no suggestion of disease transmission. Overall, patient and graft survival in recipients of organs from donors with M/E were similar to those for all other types of deceased organ donor. CONCLUSION: Donors dying with M/E represent a valuable source of organs for transplantation. The risk of disease transmission is low but, where the causative agent is unknown, caution is required. PMID- 27699933 TI - Effect of AKT3 expression on MYC- and caspase-8-dependent apoptosis caused by polo-like kinase inhibitors in HCT 116 cells. AB - Polo-like kinase (PLK) is a cell-cycle regulator that is overexpressed in several cancer cell types. Polo-like kinase is considered a novel target for cancer therapies, and several PLK inhibitors (PLKis), including BI 2536, BI 6727, and GSK461364, have been developed. In this study, we established five BI 2536 resistant cell lines from human colorectal cancer HCT 116 cells, to explore the resistance mechanism and identify predictable biomarkers of PLKis. We showed that PLKi-induced caspase-8 activation was attenuated in the BI 2536-resistant cell lines. We also showed that the expression of P-glycoprotein (P-GP) and AKT3 was upregulated, whereas that of MYC was downregulated in some BI 2536-resistant cell lines. Expression of P-GP conferred resistance to PLKis, and PLKi-induced apoptosis was dependent on MYC and caspase-8 in HCT 116 cells. We also showed for the first time that AKT3 suppressed BI 6727-induced caspase-8 activation and conferred resistance to PLKis. Collectively, these results indicate that MYC, caspase-8, P-GP, and AKT3 play critical roles in PLKi-induced apoptosis. Therefore, they are candidate biomarkers of the pharmacological efficacy of PLKis. PMID- 27699936 TI - Diagnostic accuracy of des-gamma-carboxy prothrombin for hepatocellular carcinoma in a French cohort using the Lumipulse(r) G600 analyzer. AB - The increasing incidence of hepatocellular carcinoma (HCC) in Western countries requests reliable tumour markers for preclinical diagnosis. We evaluated the diagnostic accuracy of des-gamma-carboxy prothrombin (DCP), in comparison with alpha-fetoprotein (AFP) in a French cohort using a new analyser. One hundred and sixty-two patients with virus-related cirrhosis (46 HCC patients and 116 controls) were recruited in this retrospective proof-of-concept study. DCP was measured on new Lumipulse(r) G600 analyzer and AFP on usual Cobas e602 analyzer in serum samples that were collected at the time of HCC diagnosis for HCC patients or during follow-up for controls. DCP and AFP levels were higher in HCC patients. The area under receiver operating characteristic curve was larger for DCP than for AFP (0.89 vs 0.77, P=.03). At the cut-off value of 128 mAU/mL, sensitivity and specificity for DCP were 74% and 92%. At the cut-off value of 20 MUg/L, sensitivity and specificity for AFP were 63% and 82%. NRI>0 for the association of "AFP+DCP" were 101%, P<.0001, and 23%, P=.03, compared to "AFP" or "DCP" alone, respectively. We conclude that DCP outperformed AFP for the detection of HCC.

AB - Brain-derived neurotrophic factor (BDNF) is a growth factor that is dynamically expressed in the brain across postnatal development, regulating neuronal differentiation and synaptic plasticity. The neurotrophic hypothesis of psychiatric mood disorders postulates that in the adult brain, decreased BDNF levels leads to altered neural plasticity, contributing to disease. Although BDNF has been established as a key factor regulating the critical period plasticity in the developing visual system, it has recently been shown to also play a role in fear circuitry maturation, which has implications for the emergence of fear related mood disorders. This review provides a detailed overview of developmental changes in expression of BDNF isoforms, as well as their receptors across postnatal life. In addition, recent developmental studies utilizing a genetic BDNF single nucleotide polymorphism (Val66Met) knock-in mouse highlight the impact of BDNF on fear learning during a sensitive period spanning the transition into adolescent time frame. We hypothesize that BDNF in the developing brain regulates fear circuit plasticity during a sensitive period in early adolescence, and alterations in BDNF expression (genetic or environmental) have a persistent impact on fear behavior and fear-related disorders. PMID- 27699938 TI - Kappa-Opioid Antagonists for Psychiatric Disorders: From Bench to Clinical Trials. AB - Kappa-opioid receptor (KOR) antagonists are currently being considered for the treatment of a variety of neuropsychiatric conditions, including depressive, anxiety, and substance abuse disorders. A general ability to mitigate the effects of stress, which can trigger or exacerbate these conditions, may explain their putative efficacy across such a broad array of conditions. The discovery of their potentially therapeutic effects evolved from preclinical research designed to characterize the molecular mechanisms by which experience causes neuroadaptations in the nucleus accumbens (NAc), a key element of brain reward circuitry. This research established that exposure to drugs of abuse or stress increases the activity of the transcription factor CREB (cAMP response element binding protein) in the NAc, which leads to elevated expression of the opioid peptide dynorphin that in turn causes core signs of depressive- and anxiety-related disorders. Disruption of KORs-the endogenous receptors for dynorphin-produces antidepressant and anxiolytic-like actions in screening procedures that identify standard drugs of these classes, and reduces stress effects in tests used to study addiction and stress-related disorders. Although interest in this target is high, prototypical KOR antagonists have extraordinarily persistent pharmacodynamic effects that complicate clinical trials. The development of shorter acting KOR antagonists together with more rapid designs for clinical trials may soon provide insight on whether these drugs are efficacious as would be predicted by preclinical work. If successful, KOR antagonists would represent a unique example in psychiatry where the therapeutic mechanism of a drug class is understood before it is shown to be efficacious in humans. PMID- 27699942 TI - Psychobiology of the intersection and divergence of depression and anxiety. PMID- 27699940 TI - Amygdala-Cortical Connectivity: Associations with Anxiety, Development, and Threat. AB - BACKGROUND: Amygdala-prefrontal cortex (PFC) functional connectivity may be influenced by anxiety and development. A prior study on anxiety found age specific dysfunction in the ventromedial PFC (vmPFC), but not amygdala, associated with threat-safety discrimination during extinction recall (Britton et al.). However, translational research suggests that amygdala-PFC circuitry mediates responses following learned extinction. Anxiety-related perturbations may emerge in functional connectivity within this circuit during extinction recall tasks. The current report uses data from the prior study to examine how anxiety and development relate to task-dependent amygdala-PFC connectivity. METHODS: Eighty-two subjects (14 anxious youths, 15 anxious adults, 25 healthy youths, 28 healthy adults) completed an extinction recall task, which directed attention to different aspects of stimuli. Generalized psychophysiological interaction analysis tested whether task-dependent functional connectivity with anatomically defined amygdala seed regions differed across anxiety and age groups. RESULTS: Whole-brain analyses showed significant interactions of anxiety, age, and attention task (i.e., threat appraisal, explicit threat memory, physical discrimination) on left amygdala functional connectivity with the vmPFC and ventral anterior cingulate cortex (Talairach XYZ coordinates: -16, 31, -6 and 1, 36, -4). During threat appraisal and explicit threat memory (vs. physical discrimination), anxious youth showed more negative amygdala-PFC coupling, whereas anxious adults showed more positive coupling. CONCLUSIONS: In the context of extinction recall, anxious youths and adults manifested opposite directions of amygdala-vmPFC coupling, specifically when appraising and explicitly remembering previously learned threat. Future research on anxiety should consider associations of both development and attention to threat with functional connectivity perturbations. PMID- 27699943 TI - Treatment for Anhedonia: A Neuroscience Driven Approach. AB - Anhedonia, or loss of interest or pleasure in usual activities, is characteristic of depression, some types of anxiety, as well as substance abuse and schizophrenia. Anhedonia is a predictor of poor long-term outcomes, including suicide, and poor treatment response. Because extant psychological and pharmacological treatments are relatively ineffective for anhedonia, there is an unmet therapeutic need for this high-risk symptom. Current psychological and drug treatments for anxiety and depression focus largely on reducing excesses in negative affect rather than improving deficits in positive affect. Recent advances in affective neuroscience posit that anhedonia is associated with deficits in the appetitive reward system, specifically the anticipation, consumption, and learning of reward. In this paper, we review the evidence for positive affect as a symptom cluster, and its neural underpinnings, and introduce a novel psychological treatment for anxiety and depression that targets appetitive responding. First, we review anhedonia in relation to positive and negative valence systems and current treatment approaches. Second, we discuss the evidence linking anhedonia to biological, experiential, and behavioral deficits in the reward subsystems. Third, we describe the therapeutic approach for Positive Affect Treatment (PAT), an intervention designed to specifically target deficits in reward sensitivity. PMID- 27699941 TI - Treatment and Prevention of Depression and Anxiety in Youth: Test of Cross-Over Effects. AB - Anxiety and depression are highly comorbid and share several common etiological processes. Therefore, it may be more efficient to develop interventions that treat or prevent these problems together rather than as separate entities. The present meta-analytic review examined whether interventions for children and adolescents that explicitly targeted either anxiety or depression showed treatment specificity or also impacted the other outcome (i.e. cross-over effects). We addressed this question both within the same type of study (i.e. treatment, prevention) and across study types. Only randomized controlled trials (RCTs) that assessed both constructs with dimensional measures were included in this review. For treatment studies, RCTs targeting anxiety (n = 18) showed significant effects on both anxious and depressive symptoms, although more strongly on anxiety than depression; similarly, RCTs treating depression (n = 9) yielded significant effects on both depressive and anxious symptoms, but stronger effects on depression than anxiety. Thus, there were cross-over effects in treatments purportedly targeting either anxiety or depression, and also treatment specificity, such that larger effects were seen for the target problem at which the treatment was aimed. Anxiety prevention studies (n = 14) significantly affected anxious, but not depressive symptoms, indicating no cross-over effect of anxiety prevention trials on depression. For depression prevention studies (n = 15), the effects were not significant for either depressive or anxiety symptoms, although the effect was significantly larger for depressive than for anxious symptoms. Post-hoc analyses revealed that the effect on depressive symptoms was significant in depression preventions trials of targeted but not universal samples. Implications for transdiagnostic interventions are discussed. PMID- 27699944 TI - Bacteria induce pigment formation in the basidiomycete Serpula lacrymans. AB - Basidiomycete fungi are characterized ecologically for their vital functional role in ecosystem carbon recycling and chemically for their capacity to produce a diverse array of small molecules. Chromophoric natural products derived from the quinone precursor atromentin, such as variegatic acid and involutin, have been shown to function in redox cycling. Yet, in the context of an inter-kingdom natural system these pigments are still elusive. Here, we co-cultured the model saprotrophic basidiomycete Serpula lacrymans with an ubiquitous terrestrial bacterium, either Bacillus subtilis, Pseudomonas putida, or Streptomyces iranensis. For each, there was induction of the gene cluster encoding a non ribosomal peptide synthetase-like enzyme (atromentin synthetase) and an aminotransferase which together produce atromentin. Correspondingly, during co culturing there was an increase in secreted atromentin-derived pigments, i.e., variegatic, xerocomic, isoxerocomic, and atromentic acid. Bioinformatic analyses from 14 quinone synthetase genes, twelve of which are encoded in a cluster, identified a common promoter motif indicating a general regulatory mechanism for numerous basidiomycetes. PMID- 27699945 TI - Cooperation in lovers: An fNIRS-based hyperscanning study. AB - This study investigated interactive exchange in lovers and the associated interpersonal brain synchronization (IBS) using functional near-infrared spectroscopy (fNIRS)-based hyperscanning. Three types of female-male dyads, lovers, friends, and strangers, performed a cooperation task during which brain activity was recorded in right frontoparietal regions. We measured better cooperative behavior in lover dyads compared with friend and stranger dyads. Lover dyads demonstrated increased IBS in right superior frontal cortex, which also covaried with their task performance. Granger causality analyses in lover dyads revealed stronger directional synchronization from females to males than from males to females, suggesting different roles for females and males during cooperation. Our study refines the theoretical explanation of romantic interaction between lovers. Hum Brain Mapp 38:831-841, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27699946 TI - Time course of hepatitis E-specific antibodies in adults. AB - Hepatitis E virus (HEV) is highly endemic in industrialized countries, but there is a lack of knowledge on individual and overall antibody concentration dynamics. The aim of this study was to characterize longitudinal concentration changes of anti-HEV immunoglobulin G (anti-HEV IgG) by enzyme immunoassay (EIA). In total, 199 serum samples collected from 45 subjects over 18 years were analysed. A wide range of anti-HEV IgG levels was found. Overall, anti-HEV IgG significantly decreased after an observation period of at least 5 years. One negative seroconversion was observed. Four individual profiles suggested single and even multiple HEV reinfections despite pre-existing HEV antibodies. PMID- 27699947 TI - Carbon-Nitrogen Bond Cleavage by a Thorium-NHC-bpy Complex. AB - Actinide complexes demonstrate unparalleled reactivity towards small molecules. However, utilizing these powerful transformations in a predictable and deliberate manner remains challenging. Therefore, developing actinide systems that not only perform noteworthy chemistry but also demonstrate controllable reactivity is a key goal. We describe a bis(NHC)borate thorium-bpy complex (1) that is capable of reductively cleaving the R-NC bond in a series of organic isocyanides. In contrast to most actinide-mediated bond activations, the dealkylation event mediated by 1 is remarkably general and yields very well-defined products that assist in mechanistic elucidation. Synthesis of the rearranged but-3-enyl product from the reaction of 1 and cyclopropylmethyl isocyanide supports the notion of a radical-based mechanism.

PMID- 27699948 TI - Reduced phosphorylation of ribosomal protein S6 is associated with sensitivity to MEK inhibition in gastric cancer cells. AB - Gastric cancer (GC) is characterized by amplifications of receptor tyrosine kinases (RTK) and KRAS, therefore, targeting of the RTK/KRAS downstream pathways could help to broaden the applicability of molecular targeted therapy for GC. We assembled a panel of 48 GC cell lines and screened predictors of responsiveness to inhibition of the RAF/MEK/ERK pathway, one of the RTK/KRAS downstream pathways. We found that GC cells with MET amplification or KRAS mutation, but not amplification, tended to be sensitive to MEK inhibition. However, several cell lines without RTK/KRAS alterations also showed high sensitivity to MEK inhibition. We then focused on the phosphorylation of RTK/KRAS downstream molecules to screen for predictors' sensitivity to MEK inhibition. We found that the phosphorylation level of mammalian target of rapamycin complex 1 (mTORC1) downstream molecules, including p70S6K, 4EBP1, and S6, was significantly associated with sensitivity to MEK inhibition in GC cells (P < 0.05), suggesting that mTORC1 activity is related to the sensitivity to MEK inhibition. Furthermore, the change in mTORC1 activity after MEK inhibition was also significantly associated with this sensitivity (P < 0.001). Among the mTORC1 downstream molecules, the change in S6 phosphorylation (pS6) showed the most significant correlation with sensitivity. Using xenograft models derived from highly sensitive and resistant cell lines, we found specific reduction of pS6 in xenografts from highly sensitive cell lines after 6 h of treatment with an MEK inhibitor. Thus, our data suggest the potential clinical applicability of an MEK inhibitor for a proportion of GC patients who could be selected on the basis of pS6 change after MEK inhibition. PMID- 27699951 TI - Muscle layer histopathology and manometry pattern of primary esophageal motility disorders including achalasia. AB - BACKGROUND: Histopathology of muscularis externa in primary esophageal motility disorders has been characterized previously. We aimed to correlate the results of high-resolution manometry with those of histopathology. METHODS: During peroral endoscopic myotomy, peroral esophageal muscle biopsy was performed in patients with primary esophageal motility disorders. Immunohistochemical staining for c kit was performed to assess the interstitial cells of Cajal (ICCs). Hematoxylin Eosin and Azan-Mallory staining were used to detect muscle atrophy, inflammation, and fibrosis, respectively. KEY RESULTS: Slides from 30 patients with the following motility disorders were analyzed: achalasia (type I: 14, type II: 5, type III: 3), one diffuse esophageal spasm (DES), two outflow obstruction (OO), four jackhammer esophagus (JE), and one nutcracker esophagus (NE). ICCs were preserved in high numbers in type III achalasia (n=9.4+/-1.2 cells/high power field [HPF]), compared to types I (n=3.7+/-0.3 cells/HPF) and II (n=3.5+/-1.0 cells/HPF). Moreover, severe fibrosis was only observed in type I achalasia and not in other types of achalasia, OO, or DES. Four of five patients with JE and NE had severe inflammation with eosinophilic infiltration of the esophageal muscle layer (73.8+/-50.3 eosinophils/HPF) with no epithelial eosinophils. One patient with JE showed a visceral myopathy pattern. CONCLUSIONS & INFERENCES: Compared to types I and II, type III achalasia showed preserved ICCs, with variable data regarding DES and OO. In disorders considered as primary esophageal motility disorders, a disease category exists, which shows eosinophilic infiltration in the esophageal muscle layer with no eosinophils in the epithelium. PMID- 27699950 TI - Improving qPCR methodology for detection of foaming bacteria by analysis of broad spectrum primers and a highly specific probe for quantification of Nocardia spp. in activated sludge. AB - AIMS: To develop qPCR broad-spectrum primers combined with a Nocardia genus specific probe for the identification of a broad spectrum of Nocardia spp. and to analyse the effects of using this developed primer and probe set on the ability to quantify Nocardia spp. in mixed DNA. METHODS AND RESULTS: The consequences of using a degenerative primer set and species-specific probe for the genus Nocardia on qPCR assays were examined using DNA extracts of pure cultures and activated sludge. The mixed DNA extracts where the target organism Nocardia flavorosea concentration ranged from 5 * 102 to 5 * 106 copies per reaction, while the background organism's DNA (Mycobacterium bovis) concentration was held at 5 * 106 copies per reaction, only produced comparable cycle threshold florescence levels when N. flavorosea concentration was greater than or equal to the background organism concentration. When concentrations of N. flavorosea were lowered in increments of 1 log, while holding M. bovis concentrations constant at 5 * 106 copies per reaction, all assays demonstrated delayed cycle threshold values with a maximum 34.6-fold decrease in cycle threshold at a ratio of 106 M. bovis: 102 N. flavorosea copies per reaction. CONCLUSIONS: The data presented in this study indicated that increasing the ability of a primer set to capture a broad group of organisms can affect the accuracy of quantification even when a highly specific probe is used. This study examined several applications of molecular tools in complex communities such as evaluating the effect of mispriming vs interference. It also elucidates the importance of understanding the community genetic make-up on primer design. SIGNIFICANCE AND IMPACT OF THE STUDY: Degenerative primers are very useful in amplifying bacterial DNA across genera, but reduce the efficiency of qPCR reactions. Therefore, standards that address closely related background species must be used to obtain accurate qPCR results. PMID- 27699952 TI - Recognition of 1,3-Butadiene by a Porous Coordination Polymer. AB - The separation of 1,3-butadiene from C4 hydrocarbon mixtures is imperative for the production of synthetic rubbers, and there is a need for a more economical separation method, such as a pressure swing adsorption process. With regard to adsorbents that enable C4 gas separation, [Zn(NO2 ip)(dpe)]n (SD-65; NO2 ip=5 nitroisophthalate, dpe=1,2-di(4-pyridyl)ethylene) is a promising porous material because of its structural flexibility and restricted voids, which provide unique guest-responsive accommodation. The 1,3-butadiene-selective sorption profile of SD-65 was elucidated by adsorption isotherms, in situ PXRD, and SSNMR studies and was further investigated by multigas separation and adsorption-desorption-cycle experiments for its application to separation technology. PMID- 27699953 TI - Ligand and Metal Effects on the Stability and Adsorption Properties of an Isoreticular Series of MOFs Based on T-Shaped Ligands and Paddle-Wheel Secondary Building Units. AB - The synthesis of stable porous materials with appropriate pore size and shape for desired applications remains challenging. In this work a combined experimental/computational approach has been undertaken to tune the stability under various conditions and the adsorption behavior of a series of MOFs by subtle control of both the nature of the metal center (Co2+ , Cu2+ , and Zn2+ ) and the pore surface by the functionalization of the organic linkers with amido and N-oxide groups. In this context, six isoreticular MOFs based on T-shaped ligands and paddle-wheel units with ScD0.33 topology have been synthesized. Their stabilities have been systematically investigated along with their ability to adsorb a wide range of gases (N2 , CO2 , CH4 , CO, H2, light hydrocarbons (C1 -C4 )) and vapors (alcohols and water). This study has revealed that the MOF frameworks based on Cu2+ are more stable than their Co2+ and Zn2+ analogues, and that the N-oxide ligand endows the MOFs with a higher affinity for CO2 leading to excellent selectivity for this gas over other species. PMID- 27699954 TI - Research Involving Health Providers and Managers: Ethical Issues Faced by Researchers Conducting Diverse Health Policy and Systems Research in Kenya. AB - There is a growing interest in the ethics of Health Policy and Systems Research (HPSR), and especially in areas that have particular ethical salience across HPSR. Hyder et al (2014) provide an initial framework to consider this, and call for more conceptual and empirical work. In this paper, we respond by examining the ethical issues that arose for researchers over the course of conducting three HPSR studies in Kenya in which health managers and providers were key participants. All three studies involved qualitative work including observations and individual and group interviews. Many of the ethical dilemmas researchers faced only emerged over the course of the fieldwork, or on completion, and were related to interactions and relationships between individuals operating at different levels or positions in health/research systems. The dilemmas reveal significant ethical challenges for these forms of HPSR, and show that potential 'solutions' to dilemmas often lead to new issues and complications. Our experiences support the value of research ethics frameworks, and suggest that these can be enriched by incorporating careful consideration of context embedded social relations into research planning and conduct. Many of these essential relational elements of ethical practice, and of producing quality data, are given stronger emphasis in social science research ethics than in epidemiological, clinical or biomedical research ethics, and are particularly relevant where health systems are understood as social and political constructs. We conclude with practical and research implications. PMID- 27699955 TI - UV-Induced Disulfide Formation and Reduction for Dynamic Photopatterning.

Both photochemical reactions allow for the spatially and temporally controlled, reversible transition between thiol- and disulfide-functionalized surfaces. The dynamic photopatterning strategy was demonstrated by the UV-induced attachment, exchange, and detachment on thiol-modified substrates.

AB - Gentisate-1,2-dioxygenase (GDO), a nonheme iron enzyme in the cupin superfamily, catalyzes the cleavage of the aromatic-ring of 2,5-dihydroxybenzoic acid (gentisic acid) to form maleylpyruvic acid in the microbial aerobic degradation of aromatic compounds. To develop a functional model of GDO, we have isolated a nonheme iron(II) complex, [(TpPh2 )FeII (DHN-H)] (TpPh2 =hydrotris(3,5 diphenylpyrazole-1-yl)borate, DHN-H=1,4-dihydroxy-2-naphthoate). In the reaction with O2 , the biomimetic complex oxidatively cleaves the aromatic ring of the coordinated substrate with the incorporation of both the oxygen atoms from molecular oxygen into the cleavage product. The presence of para-hydroxy group on the substrate plays a crucial role in directing the aromatic-ring cleaving reaction. PMID- 27699957 TI - The Vulnerability of Study Participants in the Context of Transnational Biomedical Research: From Conceptual Considerations to Practical Implications. AB - Outsourcing clinical trials sponsored by pharmaceutical companies from industrialized countries to low- (middle)-income countries - summarized as transnational biomedical research (TBR) - has lead to many concerns about ethical standards. Whether study participants are particularly vulnerable is one of those concerns. However, the concept of vulnerability is still vague and varies in its definition. Despite the fact that important international ethical guidelines such as the Declaration of Helsinki by the World Medical Association or the Ethical Guidelines for Biomedical Research Involving Human Subjects by the Council of International Organizations of Medical Sciences refer to vulnerability as ethical principle, each of their approaches are different. To overcome these shortcomings, we analyze and unite different approaches of vulnerability and develop practical criteria in order to operationalize the concept especially for the context of TBR. These criteria refer to the context of a study as well as the characteristics and the current living situation of study participants. Based on a case study of an HIV-vaccine-trial conducted in India we demonstrate how those criteria can be applied in a retrospective way to identify potential ethical conflicts. The criteria can also indicate a prospective function for ethical pre assessment. For this, we provide an outlook for three major topics: 1. Vulnerability as a normative concept: Different ways of protection; 2. The relevance of transparency and 3. Vulnerability as an instrument to increase decision participation of human subjects. PMID- 27699958 TI - Effects of Additional Acid Etching on the Dentin Bond Strengths of One-Step Self Etch Adhesives Applied to Primary Teeth. AB - OBJECTIVES: The aim of this study was to evaluate the bond strengths of one-step self-etch adhesives applied to primary tooth dentin with and without additional acid etching. MATERIALS AND METHODS: In total, 154 specimens were prepared using 50 naturally exfoliated primary molars. Four commercial one-step self-etch adhesives were used in this study: ScotchbondTM Universal, All-Bond UniversalTM, AdperTM PromptTM L-PopTM, and Clearfil S3 BondTM. Two etch-and-rinse adhesives, Prime & Bond(r) NTTM and ScotchbondTM Multi-Purpose, served as controls. Microtensile bond strength tests were performed for specimens treated with the one-step self-etch adhesives with and without additional acid etching and those treated with the two etch-and-rinse adhesives. RESULTS: All one-step self-etch adhesives except Adper Prompt L-Pop exhibited increased microtensile bond strength values (p < 0.05) with additional acid etching. A nonsignificant interaction was observed between the type of self-etch adhesive and additional acid etching (p = 0.056). Bond strength comparisons between the self-etch adhesives used without additional acid etching and the etch-and-rinse adhesives revealed significantly higher values for Prime & Bond NT than for All-Bond Universal(r) (p < 0.05). However, there were no significant differences between any etch-and-rinse adhesive and self-etch adhesive used with additional acid etching, although Clearfil S3 Bond showed greater strength than Adper Prompt L Pop. CONCLUSIONS: Our results suggest that additional acid etching increases the bond strength of most one-step self-etch adhesives applied to primary tooth dentin. CLINICAL SIGNIFICANCE: Additional acid etching of enamel and dentin can be recommended to increase the bond strength of one-step self-etch adhesives applied to primary teeth.

AB - Heavy binge drinking in adolescence can cause long-term cognitive and behavioral dysfunctions. Recent experimental evidence indicates the participation of immune system activation in the effects of ethanol in the adolescent brain and suggests gender differences. The present study aims to assess plasma cytokine and chemokine levels in male and female adolescents and young adults during acute alcohol intoxication and to correlate these results with the toll-like receptor 4 (TLR4) response. The potential role of the TLR4 signaling response was also assessed in plasma and prefrontal cortex (PFC) of adolescent wild-type and TLR4 knockout male and female mice with binge ethanol treatment. The results showed that alcohol intoxication increased the plasma levels of several cytokine and chemokine [interferon-gamma, interleukin (IL)-10, IL-17A, IL-1beta, IL-2, IL-4, IL-6, IL-8, fractalkine, monocyte chemoattractant protein 1 (MCP-1) and macrophage inflammatory protein 1alpha (MIP-1alpha)] and the upregulation of TLR4 mRNA levels occurred in intoxicated females, while elevation of colony stimulating factor was only observed in the plasma of males. In wild-type female adolescent mice, intermittent ethanol treatment increased the levels of several cytokines (IL-17A and IL-1beta) and chemokines (MCP-1, MIP-1alpha and fractalkine) in PFC and in serum (IL-17A, MCP-1 and MIP-1alpha), but significant differences in the fractalkine levels in PFC were observed only in male mice. No changes in serum or prefrontal cortex cytokine and chemokine levels were noted in ethanol-treated male or female TLR4-knockout mice. Our findings revealed that females are more vulnerable than males to inflammatory effects of binge ethanol drinking and suggested that TLR4 is an important target of ethanol-induced inflammation and neuroinflammation in adolescence. PMID- 27699961 TI - Pheophytin a isolated from the seagrass Syringodium isoetifolium plausibly blocks umuC proteins of select bacterial pathogens, in silico. AB - AIMS: This investigation is designed to evaluate the antibacterial efficiency of the noodle grass Syringodium isoetifolium, which is commonly found in the Indian coastal waters. Also, this study characterizes the active compound and predicts the mode of action in silico. METHODS AND RESULTS: Human pathogenic bacteria were treated with crude metabolites of S. isoetifolium. The potent fraction b was analysed by UV/VIS, Spectroscopy RP-HPLC, FT-IR, ESI-Mass and 1 H and 13 C NMRs and determined to be a hydrate of pheophytin a (C55 H74 N4 O6 ). The isolated compound Pheo had MIC values of 6.2 +/- 0.7 (Salmonella typhi) and 12.5 +/- 0.8 (Escherichia coli and Pseudomonas aeruginosa) MUg ml-1 . Molecular docking studies of the compound were done to find the binding sites on the pathogens using a Molegro Virtual Docker platform. Pheo targets umuC proteins by binding compactly to five amino acid residues with interaction energy of -3.66 and a Moldock score of -160.175. CONCLUSIONS: Hence, we conclude that pheophytin a, besides being an accessory photosynthetic pigment, also has proven to be antibacterial against human pathogens. Lesser MIC values with definite binding sites predicted in silico are suggestive of a precise of action for this compound. SIGNIFICANCE AND IMPACT OF THE STUDY: Easy extraction methods of the active compound that has a definite target render this under-explored seagrass a good source of antibacterial compound against human pathogenic bacteria. This learning may favour more researches in this unexplored area to build up Pheo based natural products as antibiotic therapies.

AB - Selective inhibition of the transporter protein sodium-glucose cotransporter 2 (SGLT2) has emerged as a promising way to control blood glucose level in diabetes patients. Reported herein is a short and convergent synthetic route towards some small-molecule SGLT2 inhibitors by a chemo- and diastereospecific palladium catalyzed arylation reaction. This synthetic strategy enabled the discovery of two highly selective and potent SGLT2 inhibitors, thereby paving the way towards the development of carbasugar SGLT2 inhibitors as potential antidiabetic/antitumor agents.

AB - Frankincense (olibanum) is one of the oldest aromatic materials used by humans, but the key molecular constituents contributing to its characteristic odor remained unknown. Reported herein is the discovery that (1S,2S)-(+)-trans- and (1S,2R)-(+)-cis-2-octylcyclopropyl-1-carboxylic acids are highly potent and substantive odorants occurring in ppm amounts in all of the frankincense samples analyzed, even those showing radically different volatile compositions. These cyclopropyl-derived acids provide the very characteristic old churchlike endnote of the frankincense odor. PMID- 27699964 TI - Comparison of different consensuses of BTXA in different countries. AB - The most international dosing guidelines on the use of botulinum toxin type A (BTXA) drugs support a 1:1 dose relationship between OnaBTXA and IncoBTXA and 1:2.5 between OnaBTXA and AboBTXA. However, different facial zones demonstrate different doses conversion ratios. The comparative analysis of nine consensuses on the use of Abo-, Ona-, and IncoBTXA in the United States, Russia, and Europe has been performed. We conducted a review of publications adopting the key words "botulinum toxin consensus," "botulinum toxin guideline." Information search has been carried out primarily in specialized databases (DB). To find the relevant RCTs and guidelines/consensuses, the following databases were used: PubMed and Medline that were screened up to May 2008. Results regarding dose ratios for OnaBTXA:AboBTXA and IncoBTXA:AboBTXA showed that in most cases it is characterized both by increase and by decrease compared to the ratio of 1:2.5. The mean value of dose ratios OnaBTXA:AboBTXA adopted in the United States is 1:2.8. The ratio IncoBTXA:AboBTXA according to international and Russian data is 1:1.9. There are some differences in clinical approach of BTXA use in certain countries. In Russia, low doses are recommended for "crow's feet" and forehead. The US consensus recommends a higher dosage to correct perioral wrinkles. Despite many years of experience in using BTXA, there is no strict international uniformity of clinical guidelines. The recommended doses for the individual areas of the face may differ in different countries. Therefore, physicians in their practice should be guided not by international consensuses, but prefer a national guidelines. PMID- 27699965 TI - Norovirus infection in solid organ transplant recipients: a single-center retrospective study. AB - BACKGROUND: Norovirus (NoV) is gaining recognition as an important cause of diarrhea among solid organ transplant (SOT) recipients, but existing studies have been limited by a small sample size. METHODS: We conducted a retrospective study of all adult SOT recipients diagnosed with NoV between 2006 and 2013 and compared their data to that of adult SOT recipients with diarrhea who tested negative for NoV during that time. RESULTS: A total of 192 patients with diarrhea had stool NoV testing as part of their work-up during the study period; of these patients, 35% (67) tested positive for NoV. Of patients with diarrhea without NoV, Clostridium difficile (25%) and cytomegalovirus (12%) were the most commonly identified infectious cause of diarrhea. Diarrheal duration was significantly protracted in NoV patients, with an average of 241 days vs 75 days in the control group (P=.0007). One patient death and 2 graft failures were related to the NoV illness within the first month after the onset of diarrhea, and 30% of NoV patients had a >=20% increase in creatinine within 1 year of diagnosis. These outcomes did not differ significantly from those of SOT patients with diarrhea in the non-NoV group. CONCLUSIONS: NoV is a common cause of diarrhea among SOT recipients at our institution and is responsible for a very prolonged course of chronic diarrhea.

PMID- 27699969 TI - Monitoring Salmonella, Campylobacter, Escherichia coli and Staphylococcus aureus in traditional free-range 'Label Rouge' broiler production: a 23-year survey programme. AB - AIM: 'Label Rouge' broiler free-range carcasses have been monitored since 1991, and broiler flocks since 2010, for contamination by the main foodborne zoonotic bacteria. METHODS AND RESULTS: Initially, the monitoring plan mainly focused on the surveillance of Salmonella, and on indicators of the overall microbiological quality of free-range broiler carcasses such as Staphylococcus aureus and coliforms, but was extended in 2007 to include Campylobacter enumeration on carcasses and in 2010, to Salmonella in the environment of live birds. Salmonella contamination of free-range broiler carcasses rose to a peak of 16% in 1994 but less than 1% of carcasses are now regularly found to be positive. Indicators of the overall microbiological quality of carcasses are also improving. These results correlate with the low prevalence of Salmonella in free-range broiler breeding and production flocks, and with the continuous improvement of hazard analysis and critical control points in slaughterhouses, the implementation of a good manufacturing practice guide since 1997 and the application of EU regulations on Salmonella since 1998 in France. Regarding Campylobacter counts on carcasses, the situation has been improving continuously over the last few years, even if 2.5% of the carcasses are still contaminated by more than 1000 Campylobacter per g of skin. CONCLUSIONS: Although the current control system focusing on Salmonella is based on firm epidemiologic data and offers effective means of control (e.g. slaughtering of positive breeder flocks), existing information on Campylobacter makes it more difficult to formulate an effective control plan for free-range broilers, due to their particular exposure to environmental contamination. SIGNIFICANCE AND IMPACT OF THE STUDY: This long-term surveillance programme provided an extended view of the evolution of the contamination of free-range broilers and a direct measurement of the impact of mandatory and profession-driven interventions on the microbiological quality of carcasses.

PMID- 27699971 TI - Robot-assisted approach improves surgical outcomes in obese patients undergoing partial nephrectomy. AB - OBJECTIVES: To assess the impact of approach on surgical outcomes in otherwise healthy obese patients undergoing partial nephrectomy for small renal masses. PATIENTS AND METHODS: Using our institutional partial nephrectomy database, we abstracted data on otherwise healthy (Charlson comorbidity score <=1 and bilateral kidneys), obese patients (body mass index >30 kg/m2 ) with small renal masses (<4 cm) treated between 2011 and 2015. The primary outcomes were intra operative transfusion, operating time, length of hospital stay (LOS), and postoperative complications. The association between approach, open (OPN) vs robot-assisted partial nephrectomy (RAPN), and outcomes was assessed by univariable and multivariable logistic regression analyses. Covariates included age, gender, obesity severity, tumour size and tumour complexity. RESULTS: Of 237 obese patients undergoing partial nephrectomy, 25% underwent OPN and 75% underwent RAPN. Apart from larger tumour size in the OPN group (2.8 vs 2.5 cm; P = 0.02), there was no significant difference between groups. The rate of intra operative blood transfusion (1.1 vs 10%; P = 0.01), the median operating time (180 vs 207 min; P < 0.01) and the median ischaemia time (19.5 vs 27 min; P < 0.01) were all greater for OPN. The LOS was significantly shorter for RAPN (3 vs 4 days; P < 0.01). While the overall complication rate was higher for OPN (15.8 vs 31.7%; P < 0.01), major complications were not significantly different (5.6 vs 1.7%; P = 0.20). On multivariable analyses, OPN independently predicted longer operating time, longer length of stay, and more overall complications. CONCLUSIONS: At a high-volume centre, the robot-assisted approach offers less blood transfusion, shorter operating time, faster recovery, and fewer peri operative complications compared with the open approach in obese patients undergoing partial nephrectomy for small renal masses. In this setting, RAPN may be a preferable treatment option. PMID- 27699970 TI - Asymptomatic cryptococcal antigen prevalence detected by lateral flow assay in hospitalised HIV-infected patients in Sao Paulo, Brazil. AB - OBJECTIVE: To determine the prevalence of asymptomatic cryptococcal antigen (CRAG) using lateral flow assay (LFA) in hospitalised HIV-infected patients with CD4 counts <200 cells/MUl. METHODS: Hospitalised HIV-infected patients were prospectively recruited at Instituto de Infectologia Emilio Ribas, a tertiary referral hospital to HIV-infected patients serving the Sao Paulo State, Brazil. All patients were >18 years old without prior cryptococcal meningitis, without clinical suspicion of cryptococcal meningitis, regardless of antiretroviral (ART) status, and with CD4 counts <200 cells/MUl. Serum CRAG was tested by LFA in all patients, and whole blood CRAG was tested by LFA in positive cases. RESULTS: We enrolled 163 participants of whom 61% were men. The duration of HIV diagnosis was a median of 8 (range, 1-29) years. 26% were antiretroviral (ART)-naive, and 74% were ART-experienced. The median CD4 cell count was 25 (range, 1-192) cells/MUl. Five patients (3.1%; 95%CI, 1.0-7.0%) were asymptomatic CRAG-positive. Positive results cases were cross-verified by performing LFA in whole blood. CONCLUSIONS: 3.1% of HIV-infected inpatients with CD4 <200 cells/MUl without symptomatic meningitis had cryptococcal antigenemia in Sao Paulo, suggesting that routine CRAG screening may be beneficial in similar settings in South America. Our study reveals another targeted population for CRAG screening: hospitalised HIV-infected patients with CD4 <200 cells/MUl, regardless of ART status. Whole blood CRAG LFA screening seems to be a simple strategy to prevention of symptomatic meningitis.

AB - A 13-year-old spayed female German shepherd dog was presented for acute onset of lethargy, anorexia, and disseminated erythematous skin lesions. Thoracic radiographs and abdominal ultrasonographic findings were consistent with metastatic hemangiosarcoma. Multiple, ill-defined, irregularly shaped hypoechoic nodules were also detected within the thoracic and abdominal wall. Hemangiosarcoma metastases to the skeletal muscle were confirmed based on histopathological examination. Multivisceral involvement was also confirmed by necropsy. Metastatic neoplasia should be considered as a differential diagnosis for dogs with ill-defined, irregular, hypoechoic, intramuscular nodules. PMID- 27699975 TI - Targeted Nanoparticle Thermometry: A Method to Measure Local Temperature at the Nanoscale Point Where Water Vapor Nucleation Occurs. AB - An optical nanothermometer technique based on laser trapping, moving and targeted attaching an erbium oxide nanoparticle cluster is developed to measure the local temperature. The authors apply this new nanoscale temperature measuring technique (limited by the size of the nanoparticles) to measure the temperature of vapor nucleation in water. Vapor nucleation is observed after superheating water above the boiling point for degassed and nondegassed water. The average nucleation temperature for water without gas is 560 K but this temperature is lowered by 100 K when gas is introduced into the water. The authors are able to measure the temperature inside the bubble during bubble formation and find that the temperature inside the bubble spikes to over 1000 K because the heat source (optically-heated nanorods) is no longer connected to liquid water and heat dissipation is greatly reduced.

AB - RNA is essential for all kingdoms of life and exerts important functions beyond transferring genetic information from DNA to protein. With the advent of the state-of-the-art deep sequencing technology, a large portion of noncoding transcripts in eukaryotic genomes has been broadly identified. Among them, long noncoding RNAs (lncRNAs) have been emerged as a new class of RNA molecules that have regulatory potential in a variety of physiological and pathological processes. Here we summarize recent research progresses that have been made by scientists in China on lncRNAs, including their biogenesis, functional implication and the underlying mechanism of action at the current stage.

AB - As a long-time scholar of science and art practices, I look particularly at the role of tools and instruments which make these practices possible. I note that science, historically, has favoured visualist imaging, but art, particularly in performance modes, often uses acoustic imaging. Early modern science was dominantly optical in instrumentation, but uses of optics often preceded science use in early modern times. In late modern times, much more complex instrumentation often originated in the sciences, but artists frequently adapted to acoustic practices. Sonifying science, from imaging space phenomena to medical phenomena, is traced here, focusing upon medical sonification in detecting cancers. PMID- 27699984 TI - Two sides of a coin: host-plant synchrony fitness trade-offs in the population dynamics of the western spruce budworm. AB - Conifer-feeding budworms emerge from overwintering sites as small larvae in early spring, several days before budburst, and mine old needles. These early-emerging larvae suffer considerable mortality during this foraging period as they disperse in search of available, current-year buds. Once buds flush, surviving budworms construct feeding shelters and must complete maturation before fresh host foliage senesces and lignifies later in the summer. Late-developing larvae suffer greater mortality and survivors have lower fecundity when feeding on older foliage. Thus, there is a seasonal trade-off in fitness associated with host synchrony: early emerging budworms have a greater risk of mortality during spring dispersal but gain better access to the most nutritious foliage, while, on the other hand, late emerging larvae incur a lower risk during the initial foraging period but must contend with rapidly diminishing resource quality at the end of the feeding period. We investigate the balance that results from these early-season and late season synchrony fitness trade-offs using the concept of the phenological window. Parameters associated with the variation in the phenological window are used to estimate generational fitness as a function of host-plant synchrony. Because defoliation modifies these relationships, it is also included in the analysis. We show that fitness trade-offs characterizing the phenological window result in a robust synchrony relationship between budworm and host plant over a wide geographic range in southern British Columbia, Canada.

PMID- 27699982 TI - Unsung renal receptors: orphan G-protein-coupled receptors play essential roles in renal development and homeostasis. AB - Recent studies have shown that orphan GPCRs of the GPR family are utilized as specialized chemosensors in various tissues to detect metabolites, and in turn to activate downstream pathways which regulate systemic homeostasis. These studies often find that such metabolites are generated by well-known metabolic pathways, implying that known metabolites and chemicals may perform novel functions. In this review, we summarize recent findings highlighting the role of deorphanized GPRs in renal development and function. Understanding the role of these receptors is critical in gaining insights into mechanisms that regulate renal function both in health and in disease. PMID- 27699986 TI - Unresolved attachment and agency in women victims of intimate partner violence: A case-control study. AB - OBJECTIVES: Women victims of IPV are more likely insecurely attached and have experienced childhood abuse, which according to the attachment theory is deeply related to disorganized attachment. This case-control study was performed with the aim to compare the attachment status and the defensive processing patterns of women victims of IPV (cases) with women with no experiences of IPV (controls). METHODS: Cases were 16 women with an age range from 26 years to 51 years. The control group included 16 women with an age range from 26 years to 59 years. Women's states of mind in regard to attachment were evaluated with the Adult Attachment Projective Picture System, which allows classifying attachment status and defensive mechanisms. RESULTS: Compared with control group, most IPV women resulted having an unresolved attachment status and describing characters less capable to draw upon internal resources, that is, internalized secure base, and less capable to act than controls. Women victims of IPV used significantly more words referring danger and failed protection than controls. CONCLUSIONS: The results evidenced the strong effectiveness of the AAP on analysing the psychological attitudes of women victims of IPV. The dramatic events lived by the women victims of IPV are so dominant in their minds that they invade their stories. This could represent a clue of emotional dysregulation. PRACTITIONER POINTS: The use of AAP improves the understanding of the agency of self and of the specific levels of trauma experienced by IPV victims, on clarifying their frightening/frightened dynamic, typical of the disorganized attachment relationship, which undermines their activity of mentalization. The therapist will assume the stance of a secure base and then both promoting exploration and contrasting impotence, humiliation, and subordination that IPV women have experienced. This therapeutic interpersonal context will be functional to reach two different but related therapeutic goals: (1) to facilitate the rebuilding of agency (through an activation of subject to explore concrete strategies for exiting from IPV), (2) to explore attachment-related segregated systems from awareness, and to integrate them in memory. PMID- 27699987 TI - Growth factor delivery of BMP9 using a novel natural bovine bone graft with integrated atelo-collagen type I: Biosynthesis, characterization, and cell behavior. AB - Within the past years, BMP9 has been characterized as one of the most osteogenic bone-inducers among the BMP family, however up until recently, BMP9 has only been available through adenovirus transfection experiments (gene therapy) not approved for clinical use. The aim of this study was to investigate recombinant rhBMP9 versus rhBMP2 at 2 concentrations (10 and 100 ng/mL) in combination with 2 bone grafts: (1) a natural bone mineral (NBM) without collagen versus (2) a novel NBM integrated with atelo-collagen type I (NBM-Col). Scanning electron microscopy revealed that while NBM demonstrated a mineralized roughened surface morphology, NBM-Col particles contained many more visible collagen fibrils throughout the scaffold surface significantly increasing rhBMP adsorption from 8 h to 10 days (as quantified by ELISA). Thereafter, ST2 preosteoblasts were used to investigate cell attachment, proliferation, and differentiation. While little change was observed for cell attachment/proliferation, osteoblast differentiation demonstrated a significant increase in alkaline phosphatase (ALP) activity when scaffolds were loaded with rhBMP9 when compared to rhBMP2. Furthermore, a 2-3 fold increase in alizarin red staining, and in mRNA levels of osteoblast differentiation markers Runx2, Collagen1alpha2, ALP, and osteocalcin was observed when rhBMP9 was combined with NBM-Col when compared to NBM without collagen at equivalent doses and when compared to rhBMP2. The results from this study demonstrate that (1) the use of rhBMP9 significantly and markedly induced osteoblast differentiation when compared to rhBMP2 and (2) the incorporation of atelo-collagen type I into NBM bone grafts markedly improved these findings by serving as a scaffold capable of improving growth factor adsorption and osteoblast behavior.

AB - OBJECTIVE: The aim of this study was to describe prehospital use of ketamine by ACT Ambulance Service, and frequency of endotracheal intubation. METHODS: This was a retrospective study of patients receiving prehospital ketamine between 1 January and 31 December 2013. Episodes were identified from the prehospital electronic patient care records, then linkage to ED records at two receiving hospitals. Demographics, dose, indication and occasions of intubation were analysed. RESULTS: A total of 163 episodes were identified; 10 of these were excluded because of lack of identifying data or missing records (age 1-97 years [mean: 43, standard deviation: 21.7], 56% men). Median total dose was 60 mg (interquartile range 70; 5-400 mg) in three doses (interquartile range 3; 1-14 mg). For patients with a weight recorded (63%), median dose was 0.73 mg/kg. Indications were analgesia 68%, agitation/combative 25%, rapid sequence intubation 5% and others 2%. A total of 26 patients were endotracheally intubated, 11 prehospital (seven as an intended rapid sequence intubation and four combative patients with return of spontaneous circulation) and 15 in the ED. Of ED intubations, 10 were trauma patients and five were drug ingestion related. Patients receiving ketamine for combativeness were more likely to be intubated than those receiving it for analgesia (25 vs 7.2%; odds ratio: 3.46; 95% confidence interval: 1.12, 10.71). In those with a weight recorded, the mg/kg dose was not associated with subsequent intubation. CONCLUSIONS: Median dose for analgesia was comparable with other studies; dose for sedation was less than reported elsewhere. Intubation rate for patients receiving prehospital ketamine was 17%. Further study is recommended to assess the ED course of the non intubated group of patients, and consideration should be given to non-weight based methods of dose selection.

PRACTICE IMPLICATIONS: It is important to apply appropriate nursing interventions for these mothers during the postpartum period. PMID- 27699993 TI - Transient elastography for the diagnosis of liver fibrosis: a systematic review of economic evaluations. AB - BACKGROUND: Liver biopsy remains the gold standard for the diagnosis of liver fibrosis, but its use as a diagnostic tool is limited by its invasive nature and high cost. OBJECTIVE: The aim of this study was to systematically review the cost effectiveness of transient elastography (TE) with and without controlled attenuation parameter (CAP) for the diagnosis of liver fibrosis or steatosis in patients with hepatitis B, hepatitis C, alcoholic liver disease and non-alcoholic fatty liver disease. METHODS: An economic literature search was performed. Eligibility criteria included systematic reviews, health technology assessments or economic evaluations of TE compared to liver biopsy and other non-invasive tests. After abstract screening, full-text reports of potentially relevant articles were assessed in duplicate. The methodological quality of the included studies was also appraised. RESULTS: The database search yielded 253 records; four cost-effectiveness and four cost-utility studies were included. The methodological quality of the included studies varies. High-quality cost effectiveness studies not only suggested that TE is less costly but also less accurate than liver biopsy. The incremental cost-effectiveness ratio (ICER) of TE improves with a greater level of diagnostic accuracy and a higher degree of liver fibrosis. High-quality cost-utility studies indicated that TE is a cost-effective alternative to biopsy with ICER between $9000 and $14 000 per QALY for patients with hepatitis C. We did not find studies that assessed the cost-effectiveness of TE with CAP for the diagnosis of liver steatosis. CONCLUSIONS: Transient elastography is an economically attractive alternative to liver biopsy and other non-invasive diagnostic tests especially for patients with a higher degree of liver fibrosis. PMID- 27699992 TI - Combined analysis of cross-reacting antibodies anti-beta1AR and anti-B13 in advanced stages of Chagas heart disease. AB - OBJECTIVE: Autoantibodies cross-reacting with the beta1 adrenergic receptor (anti beta1AR and anti-p2beta) and cardiac myosin antigens (anti-B13) have been related to the pathogenesis of chronic Chagas heart disease (CCHD). Studies exploring their levels in different stages are scarce. We aimed to evaluate the relationship of these autoantibodies with the clinical profile of chronic patients, especially regarding their classificatory accuracy in severe presentation with heart failure. METHODS AND RESULTS: We conducted a cross sectional study of 155 T. cruzi-seropositive patients and 26 age- and gender matched healthy controls. They were categorised in three stages of CCHD. Serum antibodies were measured by specific immunoassays. Symptomatic individuals showed increased levels of anti-beta1AR and anti-B13, while anti-p2beta antibodies were similar between groups. A composite logistic regression model including anti-B13, anti-beta1AR antibody levels and age was able to predict systolic heart failure yielding an area under the curve of 83% (sensitivity of 67% and specificity of 89%). CONCLUSIONS: In our study, anti-beta1AR and anti-B13 antibodies were higher in individuals with chronic Chagas heart disease stage III, mainly in those with dilated cardiomyopathy associated with systolic heart failure. Logistic regression analysis showed that both antibodies were good predictors of severe CCHD. As well as being involved in disease progression, anti-beta1AR and anti-B13 antibodies may be used as a serum marker of poor prognosis in terms of heart compromise. PMID- 27699994 TI - Degradation of alkanethiol self-assembled monolayers in mesenchymal stem cell culture. AB - Alkanethiol self-assembled monolayers (SAMs) have been used extensively in studying the role of surface functionality and geometry on stem cell differentiation; however, the effects of stem cell culture conditions on SAM stability over time are not well understood. In this work, we examined the physical and chemical changes occurring on gold (Au)-SAM surfaces over time as a function of Au thickness. Within a narrow range of thicknesses (4, 8, and 10 nm), we observed significant differences in temporal SAM stability for a commonly utilized, hydrophilic, protein and cell repulsive oligo(ethylene) glycol alkanethiol (HS-(CH2 )11 (O(CH2 )2 )6 OH) SAM and the hydrophobic, protein adhesive hexadecanethiol (SH-(CH2 )15 CH3 ) SAM. Within both acellular and stem cell culture conditions, 8 nm Au resulted in the most stable SAMs (~7 days). The 4 and 10 nm Au SAMs exhibited loss in stability following 5 days at varying degradation rates, showing 4 nm Au to be the least stable. Migration of human mesenchymal stem cells seeded on SAM surfaces showed that SAM degradation rates in acellular conditions were directly correlated with the cellular migration behavior. Findings of this study can be used to develop SAM surfaces with controlled degradation rates for applications in stem cell engineering and regenerative medicine. (c) 2016 Wiley Periodicals, Inc.

PMID- 27699995 TI - Synthesis of ZnSe and ZnSe:Cu quantum dots by a room temperature photochemical (UV-assisted) approach using Na2 SeO3 as Se source and investigating optical properties. AB - In this study, ZnSe and ZnSe:Cu quantum dots (QDs) were synthesized using Na2 SeO3 as the Se source by a rapid and room temperature photochemical (UV-assisted) approach. Thioglycolic acid (TGA) was employed as the capping agent and UV illumination activated the chemical reactions. Synthesized QDs were successfully characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), photoluminescence (PL) and UV-visible (UV-vis) spectroscopy, Fourier transform-infrared (FT-IR), and energy dispersive X-ray spectroscopy (EDX). XRD analysis demonstrated the cubic zinc blend phase QDs. TEM images indicated that round-shaped particles were formed, most of which had a diameter of about 4 nm. The band gap of the ZnSe QDs was higher than that for ZnSe in bulk. PL spectra indicated an emission with three peaks related to the excitonic, surface trap states and deep level (DL) states. The band gap and QD emission were tunable only by UV illumination time during synthesis. ZnSe:Cu showed green emission due to transition of electrons from the Conduction band (CB) or surface trap states to the 2 T2 acceptor levels of Cu2+ . The emission was increased by increasing the Cu2+ ion concentration, such that the optimal value of PL intensity was obtained for the nominal mole ratio of Cu:Zn 1.5%.

Therefore, this article intends to evaluate the usefulness of CL in the South through the prism of obligations and goals entrusted to patent holders (the effective and non-abusive exploitation of patents in order to achieve industrial and health developments) and in light of experiences in Thailand and Brazil regarding access to antiretroviral drugs. In this way, it shows that the obligations assigned to patent holders were better served by the recipients of CL and brought significant health and industrial benefits in the two high middle-income countries. In particular, CL allowed the scaling-up of free and universal access to antiretroviral drugs by assuring the financial sustainability of these public health programs endangered by monopolistic practices from patent holders.

AB - PURPOSE: This study evaluated the association between excess weight and quality of life (QoL), symptoms of anxiety, caries experience and socio-economic factors in a representative sample of 8- to 10-year-old children from three public schools of Piracicaba (SP, Brazil). MATERIALS AND METHODS: The Autoquestionnaire Qualite de Vie Enfant Image was applied to explore family and social relations, activities, health, body functions and separation domains, and, by means of the Multidimensional Anxiety Scale for Children, symptoms of anxiety were screened. Clinical examination was performed using DMFT/dmft indexes to assess oral health and caries experience. Medical and nutritional history, parents' schooling, monthly income and ownership of household goods and services were also evaluated. RESULTS: Of the 313 subjects included, four subjects were underweight, 188 normal weight, 67 overweight and 54 presented obesity (38.7% with excess weight). Measures of QoL, anxiety scores and caries experience did not differ between groups. The regression model showed a significant association between excess weight and the ownership of household goods and services (OR = 5.4/CI = 1.6 18.3). CONCLUSIONS: High prevalence of excess weight was observed among prepubertal children, emphasizing the need for continued health programmes to limit risk factors for obesity. QoL, anxiety scores and caries experience did not differ between subjects with different body weights, although children from public schools with higher ownership of goods and services were more likely to present excess weight. PMID- 27699999 TI - Outpatient administration of BEAM conditioning prior to autologous stem cell transplantation for lymphoma is safe, feasible, and cost-effective. AB - High-dose BEAM chemotherapy (BCNU, etoposide, Ara-C, and melphalan) followed by autologous hematopoietic stem cell transplantation is frequently used as consolidative therapy for patients with recurrent or refractory Hodgkin or non Hodgkin lymphoma. The BEAM regimen has traditionally been administered over 6 days in the hospital, with patients remaining hospitalized until hematologic recovery and clinical stability. In an effort to reduce the length of hospitalization for these patients, our institution has transitioned from inpatient (IP) to outpatient (OP) administration of BEAM conditioning. Here, we report the results of an analysis of the feasibility, cost, complications, and outcomes for the initial group of patients who received OP BEAM compared to a prior cohort of patients who received IP BEAM. Patient and disease characteristics were comparable for the two cohorts, as were engraftment kinetics. Length of hospital stay was reduced by 6 days for the OP cohort (P < 0.001), resulting in a cost savings of more than $17,000 per patient. Fewer complications occurred in the OP cohort, including severe enteritis (P = 0.01), organ toxicities (P = 0.01), and infections (P = 0.04). Overall survival rate up to 3 years posttransplant was better for the OP cohort (P = 0.02), likely due to differences in posttransplant therapies. We conclude that OP administration of BEAM conditioning is safe and may offer significant advantages, including decreased length of hospitalization, reduced costs, decreased risks for severe toxicities and infectious complications, and likely improvement in patient satisfaction and quality of life. PMID- 27700000 TI - Identification and Characterization of microRNAs Associated With Human beta-Cell Loss in a Mouse Model. AB - Currently there is no effective approach for monitoring early beta-cell loss during islet graft rejection following human islet transplantation (HIT). Due to ethical and technical constraints, it is difficult to directly study biomarkers of islet destruction in humans. Here, we established a humanized mouse model with induced human beta-cell death using adoptive lymphocyte transfer (ALT). Human islet grafts of ALT-treated mice had perigraft lymphocyte infiltration, fewer insulin+ beta cells, and increased beta-cell apoptosis. Islet-specific miR-375 was used to validate our model, and expression of miR-375 was significantly decreased in the grafts and increased in the circulation of ALT-treated mice before hyperglycemia. A NanoString expression assay was further used to profile 800 human miRNAs in the human islet grafts, and the results were validated using quantitative real-time polymerase chain reaction. We found that miR-4454 and miR 199a-5p were decreased in the human islet grafts following ALT and increased in the circulation prior to hyperglycemia. These data demonstrate that our in vivo model of induced human beta-cell destruction is a robust method for identifying and characterizing circulating biomarkers, and suggest that miR-4454 and miR-199a 5p can serve as novel biomarkers associated with early human beta-cell loss following HIT.

AB - In this study, peptides that facilitate alcohol metabolism were purified and identified from corn protein hydrolysates. The ultra-filtered fraction with a molecular weight < 3 kDa (F3) potential activity was separated into six fractions (F3-H1-F3-H6) by semi-preparative high-performance liquid chromatography. Among the resultant six fractions, F3-H4 and F3-H5 exhibited the highest ability to eliminate alcohol in vivo. A total of 16 peptides with strong signal values were identified from F3-H4 and F3-H5 fractions by nano liquid chromatography coupled with electrospray ionization tandem mass spectrometry. Several identified peptides were then selected and synthesized to determine their potential to facilitate alcohol metabolism. We found that Leu-Leu and Pro-Phe were the key structure units in Gln-Leu-Leu-Pro-Phe responsible for this peptide's ability to facilitate alcohol metabolism. However, the role of Leu-Leu and Pro-Phe may be affected by peptide chain length and hydrophobic properties. Our results have thus provided some insight into the study of the structure-activity relationships of corn peptides. PMID- 27700006 TI - Flight or fright: training in a high-stakes zone. PMID- 27700005 TI - High-flow oxygen in patients undergoing procedural sedation in the emergency department: A retrospective chart review. AB - OBJECTIVE: Hypoxia is a recognised complication of procedural sedation. This study sought to determine whether there was an association between the use of high-flow oxygen delivery by a non-rebreather (NRB) mask during ED procedural sedation and decreased rates of hypoxia when compared with alternative oxygenation methods. METHODS: Records of all procedural sedations performed over a 12 month period in an Australian tertiary ED were reviewed retrospectively. The primary outcome was whether recorded oxygen saturations fell below 90%. Specifics of the oxygen delivery method were noted and data collected included sex, age, indication for sedation, drugs and doses administered, time of day sedation was commenced and staff grade of sedationist. RESULTS: A total of 755 procedural sedations were reviewed. Two hundred and five (27.1%) patients were administered oxygen via NRB mask from the outset of their sedation. NRB administration was associated with a statistically significant decreased rate of hypoxia (1/205 patients vs 23/550 [odds ratio: 0.112; 95% confidence interval: 0.003-0.0702]; P = 0.0090). This association remained statistically significant when adjusted for confounders. CONCLUSIONS: This study demonstrates an association with a statistically significant reduction in hypoxia when high-flow oxygen via NRB mask is administered during emergency procedural sedation. This intervention is simple, safe and inexpensive, and we would advocate that it be evaluated further in prospective trials. PMID- 27700007 TI - What the Evolution of Female Orgasm Teaches Us. PMID- 27700009 TI - Fluid manipulation on the micro-scale: Basics of fluid behavior in microfluidics. AB - Fluid manipulation on the micro-scale (microfluidics) is bringing new potential applications in a number of fields, including chemistry, biology and medicine. At sub-millimeter channel scale, some phenomena, unimportant at the macroscale, become an important force to consider when designing a microfluidics system. For example, the decrease in fluid mass causes the effects of viscosity to overcome the influence of inertia. Turbulent flow cannot be achieved at any realistic fluid velocity, making mixing a challenging task. The only phenomenon capable of blending liquids at microscale is diffusion and liquid streams can be flowed side by-side for tens of minutes before they completely fuse together. The decrease in the channel size also leads to an increased surface-to-volume ratio, which increases the importance of surface effects, including adsorption, capillary action and surface wetting and/or electric double layer formation with related electrokinetic phenomena. While rivers cannot flow uphill, a stream of liquid can easily flow up against gravity inside a capillary. Similarly, the formation of electric double layer near the charged surface of a micro-channel or capillary can be applied for electrokinetic actuating. This review summarizes selected physical phenomena related to liquid-based (water solutions) microfluidics as described recently. PMID- 27700008 TI - Translational Pharmacokinetic/Pharmacodynamic Analysis of MYO-029 Antibody for Muscular Dystrophy. AB - Suppression of the myostatin (GDF-8) pathway has emerged as an important therapeutic paradigm for muscle-wasting disorders. In this study, we conducted a translational pharmacokinetic/pharmacodynamic (PK/PD) analysis of MYO-029, an anti-myostatin monoclonal antibody, using PK data in mice, rats, monkeys, humans, mouse tissue distribution data with 125 I-labeled MYO-029, muscle weight increase in SCID mice, and muscle circumference changes in monkeys. This analysis revealed significant in vivo potency shift between mice and monkeys (72 nM vs. 1.3 MUM for 50% effect on quadriceps). Estimated central clearance of MYO-029 (0.38 mL/h/kg) in humans was greater than twofold higher than typical IgG mAbs. Peak and trough steady-state exposures of MYO-029 in patients at biweekly intravenous doses of 10 mg/kg MYO-029 are predicted to achieve only 50% and 10% of the maximum effect seen in monkeys, respectively. These retrospective analyses results suggest that the MYO-029 exposures in this trial had a low probability of producing robust efficacy.

PMID- 27700010 TI - The role of trophoblast cell receptor expression in HIV-1 passage across the placenta in pre-eclampsia: an observational study. AB - OBJECTIVE: To compare expression of markers of HIV and associated receptors (p24, CD4, CCR5 and ICAM-2) in placentae and umbilical cords of HIV-associated and pre eclamptic pregnancies to elucidate any association between these conditions in mother-to-child transmission. DESIGN: Cross-sectional immunohistochemical analysis of target receptor expression. SETTING: Laboratory-based study of primigravidae attending a district hospital in South Africa. POPULATION OR SAMPLE: Retrospectively collected placental tissue (stratified into four groups according to HIV status of normotensive and pre-eclamptic participants (n = 20/group). METHOD: Immunohistochemistry utilising CD4 (1:1), p24 (1:10), CCR5 (1:80) and ICAM-2 (1:100) antibodies was performed using light microscopy for image acquisition and analysis. MAIN OUTCOME MEASURES: Evaluate the expression of receptors on syncytiotrophoblast involved in in utero transmission of HIV. RESULTS: Syncytiotrophoblast was immunopositive for CD4 and CCR5 antibody with greater expression of CCR5 in HIV-positive versus HIV-negative groups (F1,159 = 6.979, P = 0.009) and normotensive versus pre-eclamptic groups (F1,159 = 8.803, P = 0.003). p24 was present in both placentae and umbilical cords of babies that were HIV-negative at 6 weeks. ICAM-2 immunostaining was observed in the syncytiotrophoblast across study groups and was significantly higher in the HIV negative pre-eclamptic group (chi2 (3) = 45.3; P < 0.001). CONCLUSION: Concurrent CD4 and CCR5 receptor expression demonstrates possible in utero viral entry routes across the placental barrier. ICAM-2 expression may influence HIV passage across the placenta or restoration of risk of pre-eclampsia in HAART treated mothers. HIV was found in fetal circulation regardless of antiretroviral treatment. Further confirmatory ultrastructural and molecular work is warranted. TWEETABLE ABSTRACT: CD4, CCR5 and ICAM-2 on syncytiotrophoblast may facilitate HIV infection of passage across the placenta. PMID- 27700012 TI - Chemical constituents and quality control of two Dracocephalum species based on high-performance liquid chromatographic fingerprints coupled with tandem mass spectrometry and chemometrics. AB - Two similar Dracocephalum species, namely, Dracocephalum tanguticum Maxim and Dracocephalum moldavica L, are commonly used as ethnic medicines in China. Here we describe a strategy of combining high-performance liquid chromatography with quadrupole time-of-flight mass spectrometry, as well as fingerprints and chemometrics for characterization and discrimination of chemical constituents on the two herbs. A total of 49 compounds including 33 flavonoids, 5 phenylethanol glycosides, 1 coumarin glycoside, 8 organic acids, and 2 other types of compounds were unambiguously or tentatively identified from the two Dracocephalum species. Among the compounds identified, 26 were characterized for the first time and 4 compounds, rosmarinic acid (7), salvianolic acid B (10), luteoloside (22), diosmetin-7-O-glucoside (28), were inferred as common constituents for the two herbs. Flavonoids featured in these two Dracocephalum species while their types presented significant differences. Acacetin (45) and acacetin glycosides (acatetin-7-O-glucuronide (30), acacetin-7-O-(6"-O-malonyl) glucoside (33), buddleoside (34), tilianin (35), and agastachoside (42)) were detected only in D. moldavica, which can be used to discriminate two herbal medicines. In addition, six characteristic constitutes in D. tanguticum were simultaneously quantified. Moreover, the induced chemometrics methods including similarity analysis and hierarchical clustering analysis were successfully applied for origin discrimination and quality evaluation of D. tanguticum and D. moldavica. PMID- 27700013 TI - Biomaterials in siRNA Delivery: A Comprehensive Review. AB - With the dearth of effective treatment options for prominent diseases including Ebola and cancer, RNA interference (RNAi), a sequence-specific mechanism for genetic regulation that can silence nearly any gene, holds the promise of unlimited potential in treating illness ever since its discovery in 1999. Given the large size, unstable tertiary structure in physiological conditions and negative charge of small interfering RNAs (siRNAs), the development of safe and effective delivery vehicles is of critical importance in order to drive the widespread use of RNAi therapeutics into clinical settings. Immense amounts of time and billions of dollars have been devoted into the design of novel and diverse delivery strategies, and there are a handful of delivery systems that have been successfully translated into clinic. This review provides an introduction to the in vivo barriers that need to be addressed by siRNA delivery systems. We also discuss the progress up to the most effective and clinically advanced siRNA delivery systems including liposomal, polymeric and siRNA conjugate delivery systems, as well as their design to overcome the challenges. PMID- 27700014 TI - Synthesis and cytotoxic activity of certain benzothiazole derivatives against human MCF-7 cancer cell line. AB - A new series of benzothiazole has been synthesized as cytotoxic agents. The new derivatives were tested for their cytotoxic activity toward the human breast cancer MCF-7 cell line against cisplatin as the reference drug. Many derivatives revealed good cytotoxic effect, whereas four of them, 4, 5c, 5d, and 6b, were more potent than cisplatin, with IC50 values being 8.64, 7.39, 7.56, and 5.15 MUm compared to 13.33 MUm of cisplatin. The four derivatives' cytotoxic activity was accompanied by regulating free radicals production, by increasing the activity of superoxide dismutase and depletion of intracellular reduced glutathione, catalase, and glutathione peroxidase activities, accordingly, the high production of hydrogen peroxide, nitric oxide, and other free radicals causing tumor cell death as monitored by reduction in the synthesis of protein and nucleic acids. Most of the tested compounds showed potent to moderate growth inhibitory activity; in particular, compound 6b exhibited the highest activity suggesting it is a lead compound in cytotoxic activity. PMID- 27700015 TI - Outcomes in patients with advanced urothelial carcinoma after discontinuation of programmed death (PD)-1 or PD ligand 1 inhibitor therapy. AB - OBJECTIVE: To study the subsequent therapy and disease outcomes of patients with advanced urothelial carcinoma (UC) after discontinuation of programmed death-1 (PD-1) or programmed death ligand 1 (PD-L1) inhibitors. PATIENTS AND METHODS: We performed a retrospective analysis to examine outcomes and systemic therapy administration after PD-1/PD-L1 inhibitor therapy in patients with advanced UC. Data on demographics and therapy administered were collected from the institutions involved in the study. Univariable Cox regression analyses were performed to examine the clinical factors potentially associated with overall survival (OS) after PD-1/PD-L1 inhibitor therapy. RESULTS: Data from 62 patients were available from four institutions, with capture of subsequent therapy and outcomes after checkpoint inhibitor immunotherapy. The median patient age was 65.5 years and 51 patients (82.3%) were male. The median (range) duration of PD 1/PD-L1 inhibitor therapy in 55 patients for whom these data were available was 64 (7-669) days. Of these, 22 patients (35.5%) received post-PD-1/PD-L1 inhibitor therapy through a variety of different chemotherapy regimens (n = 16), chemobiological combination (n = 1), biological agents (n = 4) and immunotherapy (n = 1). The median (range) time from last PD-1/PD-L1 inhibitor therapy to subsequent therapy was 58 (14-242) days. The median OS of all patients after completion of PD-1/PD-L1 inhibitor therapy was 149 days (95% confidence interval [CI]: 75-359). Among those who received some post-PD-1/PD-L1 inhibitor therapy, the median OS was 182 days (95% CI: 121-372), and the median time to progression was 124 days (95% CI: 61-273) from the start of post-PD-1/PD-L1 therapy. Among these 22 patients, the only significant baseline prognostic factor associated with OS was performance status. CONCLUSIONS: In this dataset, 35.5% of patients with advanced UC received systemic therapy after salvage therapy with PD-1/PD-L1 inhibitors. Outcomes after subsequent therapy appear similar to those historically observed in patients who had not received prior PD-1/PD-L1 inhibitor therapy. Further study of patients receiving post-PD-1/PD-L1 inhibitor therapy is warranted to identify factors associated with outcomes and potentially synergistic sequences. PMID- 27700018 TI - A hydrophobic ammonia-oxidizing archaeon of the Nitrosocosmicus clade isolated from coal tar-contaminated sediment. AB - A wide diversity of ammonia-oxidizing archaea (AOA) within the phylum Thaumarchaeota exists and plays a key role in the N cycle in a variety of habitats. In this study, we isolated and characterized an ammonia-oxidizing archaeon, strain MY3, from a coal tar-contaminated sediment. Phylogenetically, strain MY3 falls in clade 'Nitrosocosmicus' of the thaumarchaeotal group I.1b. The cells of strain MY3 are large 'walnut-like' cocci, divide by binary fission along a central cingulum, and form aggregates. Strain MY3 is mesophilic and neutrophilic. An assay of 13 C-bicarbonate incorporation into archaeal membrane lipids indicated that strain MY3 is capable of autotrophy. In contrast to some other AOA, TCA cycle intermediates, i.e. pruvate, oxaloacetate and alpha ketoglutarate, did not affect the growth rates and yields of strain MY3. The attachment of cells of strain MY3 to XAD-7 hydrophobic beads and to the adsorbent vermiculite demonstrated the potential of strain MY3 to form biofilms. The cell surface was confirmed to be hydrophobic by the extraction of strain MY3 from an aqueous medium with p-xylene. Our finding of a strong potential for surface attachment by strain MY3 may reflect an adaptation to the selective pressures in hydrophobic terrestrial environments. PMID- 27700017 TI - Mitochondrial pathway and endoplasmic reticulum stress participate in the photosensitizing effectiveness of AE-PDT in MG63 cells. AB - Photodynamic therapy (PDT) is a promising treatment in cancer therapy, with a photosensitizer activated by visible light. Aloe-emodin (AE) is a promising photosensitive agent. In this study, the photosensitizing effects and possible mechanisms of AE-PDT in MG63 cells were evaluated. The efficiency of AE-PDT was analyzed by MTT assay. The mode of cell death was investigated by Hoechst 33,342 staining and flow cytometer. The intracellular distribution of AE was detected with confocal microscopy. The formation of reactive oxygen species (ROS) was detected by DCFH-DA. The mitochondrial membrane potential (MMP) was measured by Rhodamine 123. The expression of proteins including cytochrome c, caspase-3, -9, and -12, CHOP and GRP78 was detected by western blot. Apoptosis is the primary mode of cell death in our study, which occurs in a manner of depending on AE concentration and irradiation dose. Confocal microscopy showed that AE was primarily localized on the mitochondria and endoplasmic reticulum (ER) of MG63 cells. AE-PDT resulted in rapid increases of intracellular ROS production, which reached a peak at 2 h, followed by declining of mitochondrial membrane potential, releasing of cytochrome c from mitochondria into the cytoplasm, and up-regulation of caspase-3, -9, and -12, CHOP and GRP78. These results suggest that death of MG63 cells induced by AE-PDT is triggered by ROS. Meanwhile, Mitochondria and ER serve as the subcellular targets, which are responsible for AE-PDT-induced death of MG63 cells. PMID- 27700021 TI - Selective Release of Hydrophobic and Hydrophilic Cargos from Multi-Stimuli Responsive Nanogels. AB - Highly stable multi-stimuli-responsive nanogels for selective release of simultaneously encapsulated hydrophobic and hydrophilic cargos in a spatiotemporally controlled manner are demonstrated here. The nanogel is composed of hydrophilic pH- and thermoresponsive poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) and hydrophobic photocleavable o-nitrobenzyl (ONB) linkage. The hydrophobic cargos were noncovalently encapsulated into lipophilic interiors of the nanogels, while the hydrophilic cargos were chemically linked to the nanogel precursor polymer PDMAEMA through a redox-cleavable disulfide junction. For these dual-loaded nanogels, hydrophobic cargos can be released in response to temperature, pH, and UV light, while the hydrophilic cargos can be released in response to redox reagent. The stimuli-selective release of hydrophobic and hydrophilic cargos affords the system with great potential applications in combination chemotherapy, tissue engineering, anticorrosion, and smart nanoreactors. PMID- 27700020 TI - One-Step Route to Iron Oxide Hollow Nanocuboids by Cluster Condensation: Implementation in Water Remediation Technology. AB - The fabrication procedure of hollow iron oxide nanoparticles with a large surface to volume ratio by a single-step gas condensation process at ambient temperature is presented. Fe clusters formed during the sputtering process are progressively transformed into hollow cuboids with oxide shells by the Kirkendall mechanism at the expense of oxygen captured inside the deposition chamber. TEM and Raman spectroscopy techniques point to magnetite as the main component of the nanocuboids; however, the magnetic behavior exhibited by the samples suggests the presence of FeO as well. In addition, these particles showed strong stability after several months of exposure to ambient conditions, making them of potential interest in diverse technological applications. In particular, these hierarchical hollow particles turned out to be very efficient for both As(III) and As(V) absorption (326 and 190 mg/g, respectively), thus making them of strong interest for drinking water remediation. PMID- 27700016 TI - Body mass index, weight change, and risk of second primary breast cancer in the WECARE study: influence of estrogen receptor status of the first breast cancer. AB - Studies examining the relationship between body mass index (BMI) and risk of contralateral breast cancer (CBC) have reported mixed findings. We previously showed that obese postmenopausal women with estrogen receptor (ER)-negative breast cancer have a fivefold higher risk of CBC compared with normal weight women. In the current analysis, we reexamined this relationship in the expanded Women's Environmental Cancer and Radiation Epidemiology (WECARE) Study, focusing on the impact of menopausal status and ER status of the first breast cancer. The WECARE Study is a population-based case-control study of young women with CBC (cases, N = 1386) and with unilateral breast cancer (controls, N = 2045). Rate ratios (RR) and 95% confidence intervals (CI) were calculated to assess the relationship between BMI and risk of CBC stratified by menopausal and ER status. Positive associations with obesity and weight gain were limited to women who became postmenopausal following their first primary breast cancer. Among those with an ER-negative first breast cancer, obesity (vs. normal weight) at first diagnosis was associated with an increased risk of CBC (RR = 1.9, 95% CI: 1.02, 3.4). Also, weight gain of >=10 kg after first diagnosis was associated with an almost twofold increased risk of CBC (RR = 1.9, 95% CI: 0.99, 3.8). These results suggest that women with an ER-negative first primary cancer who are obese at first primary diagnosis or who experience a large weight gain afterward may benefit from heightened surveillance. Future studies are needed to address the impact of weight loss interventions on risk of CBC. PMID- 27700022 TI - Highly Integrated Polysulfone/Polyacrylonitrile/Polyamide-6 Air Filter for Multilevel Physical Sieving Airborne Particles. AB - Rational structural design involving controlled pore size, high porosity, and particle-targeted function is critical to the realization of highly efficient air filters, and the filter with absolute particle-screen ability has significant technological implications for applications including individual protection, industrial security, and environmental governance; however, it remains an ongoing challenge. In this study, we first report a facile and scalable strategy to fabricate the highly integrated polysulfone/polyacrylonitrile/polyamide-6 (PSU/PAN/PA-6) air filter for multilevel physical sieving airborne particles via sequential electrospinning. Our strategy causes the PSU microfiber (diameter of ~1 MUm) layer, PAN nanofiber (diameter of ~200 nm) layer, and PA-6 nanonets (diameter of ~20 nm) layer to orderly assemble into the integrated filter with gradually varied pore structures and high porosity and thus enables the filter to work efficiently by employing different layers to cut off penetration of particles with a certain size that exceeds the designed threshold level. By virtue of its elaborate gradient structure, robust hydrophobicity (WCA of ~130 degrees ), and superior mechanical property (5.6 MPa), our PSU/PAN/PA-6 filter even can filtrate the 300 nm particles with a high removal efficiency of 99.992% and a low pressure drop of 118 Pa in the way of physical sieving manner, which completely gets rid of the negative impact from high airflow speed, electret failure, and high humidity. It is expected that our highly integrated filter has wider applications for filtration and separation and design of 3D functional structure in the future. PMID- 27700024 TI - Gel Polymer Electrolytes Containing Anion-Trapping Boron Moieties for Lithium-Ion Battery Applications. AB - Gel polymer electrolytes (GPEs) based on semi-interpenetrating polymer network (IPN) structure for lithium-ion batteries were prepared by mixing boron containing crosslinker (BC) composed of ion-conducting ethylene oxide (EO) chains, crosslinkable methacrylate group, and anion-trapping boron moiety with poly(vinylidene fluoride) (PVDF) followed by ultraviolet light-induced curing process. Various physical and electrochemical properties of the GPEs were systematically investigated by varying the EO chain length and boron content. Dimensional stability at high temperature without thermal shrinkage, if any, was observed due to the presence of thermally stable PVDF in the GPEs. GPE having 80 wt% of BC and 20 wt% of PVDF exhibited an ionic conductivity of 4.2 mS cm-1 at 30 oC which is one order of magnitude larger than that of the liquid electrolyte system containing the commercial Celgard separator (0.4 mS cm-1) owing to the facile electrolyte uptake ability of EO chain and anion-trapping ability of boron moiety. As a result, lithium-ion battery cell prepared using the GPE with BC showed an excellent cycle performance at 1.0 C maintaining 87 % of capacity during 100 cycles. PMID- 27700023 TI - Counter Electrode Impact on Quantum Dot Solar Cell Efficiencies. AB - The counter electrode (CE), despite being as relevant as the photoanode in a quantum dot solar cell (QDSC), has hardly received the scientific attention it deserves. In this study, nine CEs (single-walled carbon nanotubes (SWCNTs), tungsten oxide (WO3), poly(3,4-ethylenedioxythiophene) (PEDOT), copper sulfide (Cu2S), candle soot, functionalized multiwalled carbon nanotubes (F-MWCNTs), reduced tungsten oxide (WO3-x), carbon fabric (C-Fabric), and C-Fabric/WO3-x) were prepared by using low-cost components and facile procedures. QDSCs were fabricated with a TiO2/CdS film which served as a common photoanode for all CEs. The power conversion efficiencies (PCEs) were 2.02, 2.1, 2.79, 2.88, 2.95, 3.78, 3.66, 3.96, and 4.6%, respectively, and the incident photon to current conversion efficiency response was also found to complement the PCE response. Among all CEs employed here, C-Fabric/WO3-x outperforms all the other CEs, for the synergy between C-Fabric and WO3-x comes to the fore during cell operation. The low sheet resistance of C-Fabric and its high surface area due to the meshlike morphology enables high WO3-x loading during electrodeposition, and the good electrocatalytic activity of WO3-x, the very low overpotential, and its high electrical conductivity that facilitate electron transfer to the electrolyte are responsible for the superior PCE. WO3-based electrodes have not been used until date in QDSCs; the ease of fabrication of WO3 films and their good chemical stability and scalability also favor their application to QDSCs. Futuristic possibilities for other novel composite CEs are also discussed. We anticipate this study to be useful for a well-rounded development of high-performance QDSCs. PMID- 27700025 TI - Conjugated or Broken: The Introduction of Isolation Spacer ahead of the Anchoring Moiety and the Improved Device Performance. AB - Acceptors in traditional dyes are generally designed closed to TiO2 substrate to form a strong electronic coupling with each other (e.g., cyanoacrylic acid) to enhance the electron injection for the high performance of the corresponding solar cells. However, some newly developed dyes with chromophores or main acceptors isolated from anchoring groups also exhibit comparable or even higher performances. To investigate the relatively untouched electronic coupling effect in dye-sensitized solar cells, a relatively precise method is proposed in which the strength is adjusted gradually by changing isolation spacers between main acceptors and anchoring groups to partially control the electronic interaction. After an analysis of 3 different groups of 11 sensitizers, it is inferred that the electronic coupling should be kept at a suitable level to balance the electron injection and recombination. Based on a reference dye LI-81 possessing a cyanoacrylic acid as acceptor and anchoring group, both photocurrent and photovoltage are synergistically improved after the properties of isolation spacers were changed through the adjustment of the length, steric hindrance, and push-pull electronic characteristic. Accordingly, the rationally designed dye LI 87 with an isolation spacer of thiophene ethylene gives an efficiency of 8.54% and further improved to 9.07% in the presence of CDCA, showing a new way to develop efficient sensitizers.

AB - Recent reports have indicated that a manganese oxide spinel component, when embedded in a relatively small concentration in layered xLi2MnO3?(1-x)LiMO2 (M=Ni, Mn, Co) electrode systems, can act as a stabilizer that increases their capacity, rate capability, cycle life, and first-cycle efficiency. These findings prompted us to explore the possibility of exploiting lithiated cobalt oxide spinel stabilizers by taking advantage of (1) the low mobility of cobalt ions relative to manganese and nickel ions in close-packed oxides and (2) their higher potential (~3.6 V vs. Li0) relative to manganese oxide spinels (~2.9 V vs. Li0) for the spinel-to-lithiated spinel electrochemical reaction. In particular, we have revisited the structural and electrochemical properties of lithiated spinels in the LiCo1-xNixO2 (0<=x<=0.2) system, first reported almost 25 years ago, by means of high-resolution (synchrotron) X-ray diffraction, transmission electron microscopy, nuclear magnetic resonance spectroscopy, electrochemical cell tests, and theoretical calculations. The results provide a deeper understanding of the complexity of intergrown layered/lithiated spinel LiCo1-xNixO2 structures, when prepared in air between 400 and 800 degrees C, and the impact of structural variations on their electrochemical behavior. These structures, when used in low concentration, offer the possibility of improving the cycling stability, energy, and power of high energy (>=3.5 V) lithium-ion cells.

AB - Here we report a novel type of hierarchical mesoporous SnO2 nanostructures fabricated by a facile anodization method in a novel electrolyte system (an ethylene glycol solution of H2C2O4/NH4F) followed by thermal annealing at a low temperature. The SnO2 nanostructures thus obtained feature highly porous nanosheets with mesoporous pores well below 10 nm, enabling a remarkably high surface area of 202.8 m2/g which represents one of the highest values reported to date on SnO2 nanostructures. The formation of this novel type of SnO2 nanostructures is ascribed to an interesting self-assembly mechanism of the anodic tin oxalate, which was found to be heavily impacted by the anodization voltage and water content in the electrolyte. The electrochemical measurements of the mesoporous SnO2 nanostructures indicate their promising applications as lithium-ion battery and supercapacitor electrode materials. PMID- 27700028 TI - Orientation Control of Block Copolymers Using Surface Active, Phase-Preferential Additives. AB - Orientation control of thin film nanostructures derived from block copolymers (BCPs) are of great interest for various emerging technologies like separation membranes, nanopatterning, and energy storage. While many BCP compositions have been developed for these applications, perpendicular orientation of these BCP domains is still very challenging to achieve. Herein we report on a new, integration-friendly approach in which small amounts of a phase-preferential, surface active polymer (SAP) was used as an additive to a polycarbonate containing BCP formulation to obtain perpendicularly oriented domains with 19 nm natural periodicity upon thermal annealing. In this work, the vertically oriented BCP domains were used to demonstrate next generation patterning applications for advanced semiconductor nodes. Furthermore, these domains were used to demonstrate pattern transfer into a hardmask layer via commonly used etch techniques and graphoepitaxy-based directed self-assembly using existing lithographic integration schemes. We believe that this novel formulation-based approach can easily be extended to other applications beyond nanopatterning. PMID- 27700029 TI - Assessing the Increase in Specific Surface Area for Electrospun Fibrous Network due to Pore Induction. AB - The effect of pore induction on increasing electrospun fibrous network specific surface area was investigated in this study. Theoretical models based on the available surface area of the fibrous network and exclusion of the surface area lost due to fiber-to-fiber contacts were developed. The models for calculation of the excluded area are based on Hertzian, Derjaguin-Muller-Toporov (DMT), and Johnson-Kendall-Roberts (JKR) contact models. Overall, the theoretical models correlated the network specific surface area to the material properties including density, surface tension, Young's modulus, Poisson's ratio, as well as network physical properties, such as density and geometrical characteristics including fiber radius, fiber aspect ratio and network thickness. Pore induction proved to increase the network specific surface area up to 52%, compared to the maximum surface area that could be achieved by nonporous fiber network with the same physical properties and geometrical characteristics. The model based on Johnson Kendall-Roberts contact model describes accurately the fiber-to-fiber contact area under the experimental conditions used for pore generation. The experimental results and the theoretical model based on Johnson-Kendall-Roberts contact model show that the increase in network surface area due to pore induction can reach to up to 58%. PMID- 27700030 TI - Air Cushion Convection Inhibiting Icing of Self-Cleaning Surfaces. AB - Anti-icing surfaces/interfaces are of considerable importance in various engineering fields under natural freezing environment. Although superhydrophobic self-cleaning surfaces show good anti-icing potentials, promotion of these surfaces in engineering applications seems to enter a "bottleneck" stage. One of the key issues is the intrinsic relationship between superhydrophobicity and icephobicity is unclear, and the dynamic action mechanism of "air cushion" (a key internal factor for superhydrophobicity) on icing suppression was largely ignored. Here we report that icing inhibition (i.e., icing-delay) of self cleaning surfaces is mainly ascribed to air cushion and its convection. We experimentally found air cushion on the porous self-cleaning coating under vacuum environments and on the water/ice-coating interface at low temperatures. The icing-delay performances of porous self-cleaning surfaces compared with bare substrate, up to 10-40 min under 0 to ~-4 degrees C environments close to freezing rain, have been accurately real-time recorded by a novel synergy method including high-speed photography and strain sensing voltage. Based on the experimental results, we innovatively propose a physical model of "air cushion convection inhibiting icing", which envisages both the static action of trapped air pocket without air flow and dynamic action of air cushion convection. Gibbs free energy of water droplets increased with the entropy of air derived from heat and mass transfer between warmer air underneath water droplets and colder surrounding air, resulting in remarkable ice nucleation delay. Only when air cushion convection disappears can ice nucleation be triggered on suitable Gibbs free energy conditions. The fundamental understanding of air cushion on anti icing is an important step toward designing optimal anti-icing surfaces for practical engineering application. PMID- 27700031 TI - Engineering Gold Nanoparticles in Compass Shape with Broadly Tunable Plasmon Resonances and High-Performance SERS. AB - We present the uniform and high-yield synthesis of a novel gold nanostructure of compass shape composed of a Au sphere at the central and two gradually thinning conical tips at the opposed poles. The Au compass shapes were synthesized through a seed-mediated growth approach employing a binary mixture of cetyltrimethylammonium bromide (CTAB) and sodium oleate (NaOL) as the structure directing agents. Under the condition of single surfactant (CTAB), the spherical seeds tend to grow into larger spherical Au nanoparticles (NPs); while the spherical seeds favor the formation of Au compass shaped NPs using two mixed surfactants (CTAB/NaOL). The reaction kinetics clearly shows a growth mechanism of Au compass shaped NPs. Interestingly, due to their anisotropic structure, Au compass shaped NPs show two distinctive plasmonic resonances, similar to those from Au nanorods. Particularly, the longitudinal surface plasmon resonances of Au compass shaped NPs exhibit a broadly tunable range from 600 to 865 nm. In addition, the obtained Au compass shaped NPs can be self-assembled into a two dimensional monolayer with closely packed and highly aligned NPs, which results in periodic arrays of overlapped Au tips, generating hot spots for high performance surface-enhanced Raman scattering. PMID- 27700032 TI - Sodium Ion Diffusion in Nasicon (Na3Zr2Si2PO12) Solid Electrolytes: Effects of Excess Sodium. AB - The Na superionic conductor (aka Nasicon, Na1+xZr2SixP3-xO12, where 0 <= x <= 3) is one of the promising solid electrolyte materials used in advanced molten Na based secondary batteries that typically operate at high temperature (over ~270 degrees C). Nasicon provides a 3D diffusion network allowing the transport of the active Na-ion species (i.e., ionic conductor) while blocking the conduction of electrons (i.e., electronic insulator) between the anode and cathode compartments of cells. In this work, the standard Nasicon (Na3Zr2Si2PO12, bare sample) and 10 at% Na-excess Nasicon (Na3.3Zr2Si2PO12, Na-excess sample) solid electrolytes were synthesized using a solid-state sintering technique to elucidate the Na diffusion mechanism (i.e., grain diffusion or grain boundary diffusion) and the impacts of adding excess Na at relatively low and high temperatures. The structural, thermal, and ionic transport characterizations were conducted using various experimental tools including X-ray diffraction (XRD), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and electrochemical impedance spectroscopy (EIS). In addition, an ab initio atomistic modeling study was carried out to computationally examine the detailed microstructures of Nasicon materials, as well as to support the experimental observations. Through this combination work comprising experimental and computational investigations, we show that the predominant mechanisms of Na-ion transport in the Nasicon structure are the grain boundary and the grain diffusion at low and high temperatures, respectively. Also, it was found that adding 10 at% excess Na could give rise to a substantial increase in the total conductivity (e.g., ~1.2 * 10-1 S/cm at 300 degrees C) of Nasicon electrolytes resulting from the enlargement of the bottleneck areas in the Na diffusion channels of polycrystalline grains. PMID- 27700033 TI - Biosensing Probe for Quality Control Monitoring of the Structural Integrity of Therapeutic Antibodies. AB - Ideal quality control of therapeutic antibodies involves analytical techniques with high-sensitivity, high-resolution, and high-throughput performance. Few technologies that assess the physicochemical heterogeneity of antibodies, however, meet all the required demands. We developed a biosensing method for the quality control of therapeutic antibodies based on an artificial protein, AF.2A1, which discriminates between the native and the non-native three-dimensional structures of immunoglobulin G (IgG). AF.2A1 specifically recognized non-native IgG spiked into a solution of native IgG, thereby making it possible to detect contamination by a small amount of non-native IgG, which is difficult using conventional size-based separation or spectroscopic techniques. Using AF.2A1 as an analytical probe, we determined the concentration of non-native IgG formed under various pH conditions. The probe was also applicable to accelerated tests of the long-term stability of a therapeutic antibody, allowing monitoring of the formation of non-native IgG at elevated temperatures and extended periods of storage. AF.2A1, a proteinous probe, can be combined with established methods or devices to achieve high-throughput assays and provides the potential for probe based biosensing for the quality control of therapeutic antibodies. PMID- 27700034 TI - Model-guided interface probe arrangement for sensitive protein detection. AB - A wide range of analytical techniques in bioanalysis rely on surface-based biomolecular detection, which requires the confinement of probes onto heterogeneous surface to react with targets. Probe arrangement on the interface is critical for target recognition and determines assay performance. Much effort has been devoted to screen the optimized probe arrangement according to experimental tests. Such a data-driven posteriori pattern faces low efficiency, ambiguous orientation and possible deviated tested ranges from the best case. Herein we demonstrate that a model can effectively guide probe arrangement onto interface to facilitate probe-target recognition, embodied by assay of human telomerase activity with DNA-conjugated gold nanoparticles (AuNPs). Both theoretical calculation and experimental results indicate that telomerase activity is maximized on AuNP surface under guidance of model. The detection limit is at least one order of magnitude lower than that of AuNP bearing densely packed DNA, comparable to that of TRAP. Model-guided interface probe arrangement is proved to be highly useful in regulating interface recognition and may offer a new paradigm to promote surface-based biomolecular detection. PMID- 27700035 TI - NaSn2As2: An Exfoliatable Layered van der Waals Zintl Phase. AB - The discovery of new families of exfoliatable 2D crystals that have diverse sets of electronic, optical, and spin-orbit coupling properties, enables the realization of unique physical phenomena in these few-atom thick building blocks and in proximity to other materials. Herein, using NaSn2As2 as a model system, we demonstrate that layered Zintl phases having the stoichiometry ATt2Pn2 (A = Group 1 or 2 element, Tt = Group 14 tetrel element and Pn = Group 15 pnictogen element) and feature networks separated by van der Waals gaps can be readily exfoliated with both mechanical and liquid-phase methods. We identified the symmetries of the Raman active modes of the bulk crystals via polarized Raman spectroscopy. Both bulk and few-layered NaSn2As2 samples are resistant towards oxidation, with only the top surface oxidizing in ambient conditions over a couple of days. Employing angle-resolved photoemission spectroscopy (ARPES), density functional theory (DFT), and transport on bulk and exfoliated samples, we show that NaSn2As2 is a highly conducting 2D semimetal, with resistivities on the order of 10-6 Omega.m. Due to peculiarities in the band structure, the dominating p-type carriers at low temperature are nearly compensated by the opening of n-type conduction channels as temperature increases. This work further expands the family of exfoliatable 2D materials to layered van der Waals Zintl phases, opening up opportunities in electronics and spintronics. PMID- 27700036 TI - Tailoring Material Stiffness by Filler Particle Organization. AB - In the context of emerging methods to control particle organization in particle matrix composite materials, we explore, using finite element analysis, how to modulate the material bulk mechanical stiffness. Compared to a composite containing randomly distributed particles, material stiffness is enhanced 100 fold when filler particles are aligned into linear chains lying parallel to the loading direction. In contrast, chains aligned perpendicular to that direction produce negligible stiffness change. These outcomes reveal how zigzag chains, which provide intermediate results, can modulate stiffness. The stiffness decreases gradually with increasing zigzag angle theta over a range spanning two orders of magnitude. PMID- 27700037 TI - ICPMS-based Specific Quantification of Phosphotyrosine: A Gallium-tagging and Tyrosine-phosphatase Mediated Strategy. AB - Low-abundance tyrosine phosphorylation is crucial to not only normal but also aberrant life processes. We designed and synthesized a photocleavable magnetic nanoparticle-based gallium tag for tagging and enrichment as well as UV-release of the phosphate-bearing molecules/ions in cells. HPLC/71Ga species-unspecific isotope dilution (71Ga-SUID) ICP-MS was subsequently developed for specific and absolute quantification of phosphotyrosine (pY) under the assistance of a protein tyrosine phosphatase-1B (PTP-1B). pY quantification was thus achieved via determination of Ga in the Ga-phosphate complexes that come exclusively from the Ga-tagged pY. In this way, the method detection limit of pY reached down to 30 amol with the RSD lower than 5.70 % (n = 5 at pmol level). Feasibility of this proposed method was validated using VNQIGTLSEpYIK, VNQIGTLpSEpYIK and extracellular regulated protein kinase 1 peptide (-pTEpY-) standards with the recovery more than 96 % (n = 5). It was applied to the absolute quantification of pY in human breast cancer MCF-7 cells, indicating that pY increased by 1.60 nmol (61.1 %) in 3.0 * 106 MCF-7 cells after 100 nM insulin stimulation. We believe that, not limited to pY quantification, this element-tagging and protease specific reaction mediated ICP-MS methodology will pave a simple path for ever more applications of ICP-MS to the studies of quantitative protein post translational modifications (PTMs) when suitable element-tags are designed and specific proteases are available towards targeted PTMs. PMID- 27700038 TI - Energy and Electron Transfer Cascade in Self-Assembled Bilayer Dye-Sensitized Solar Cells. AB - Current high efficiency dye-sensitized solar cells (DSSCs) rely on the incorporation of multiple chromophores, via either codeposition or preformed assemblies, as a means of increasing broad band light absorption. These strategies have some inherent limitations including decreased total light absorption by each of the dyes, low surface loadings, and complex synthetic procedures. In this report, we introduce an alternative strategy, self-assembled bilayers, as a simple, stepwise method of incorporating two complementary chromophores into a DSSC. The bilayer devices exhibit a 10% increase in Jsc, Voc, and eta over the monolayer devices due to increased incident photon-to-electron conversion efficiency across the entire visible spectrum and slowed recombination losses at the interface. Directional energy and electron transfer toward the metal oxide surface are key steps in the bilayer photon-to-current generation process. These results are important as they open the door to a new architecture for harnessing broadband light in dye-sensitized devices. PMID- 27700039 TI - Digital Microfluidics for Immunoprecipitation. AB - Immunoprecipitation (IP) is a common method for isolating a targeted protein from a complex sample such as blood, serum, or cell lysate. In particular, IP is often used as the primary means of target purification for the analysis by mass spectrometry of novel biologically derived pharmaceuticals, with particular utility for the identification of molecules bound to a protein target. Unfortunately, IP is a labor-intensive technique, is difficult to perform in parallel, and has limited options for automation. Furthermore, the technique is typically limited to large sample volumes, making the application of IP cleanup to precious samples nearly impossible. In recognition of these challenges, we introduce a method for performing microscale IP using magnetic particles and digital microfluidics (DMF-IP). The new method allows for 80% recovery of model proteins from approximately microliter volumes of serum in a sample-to-answer run time of approximately 25 min. Uniquely, analytes are eluted from these small samples in a format compatible with direct analysis by mass spectrometry. To extend the technique to be useful for large samples, we also developed a macro-to microscale interface called preconcentration using liquid intake by paper (P CLIP). This technique allows for efficient analysis of samples >100* larger than are typically processed on microfluidic devices. As described herein, DMF-IP and P-CLIP-DMF-IP are rapid, automated, and multiplexed methods that have the potential to reduce the time and effort required for IP sample preparations with applications in the fields of pharmacy, biomarker discovery, and protein biology. PMID- 27700040 TI - Preparation of Hybrid Gold/Polymer Nanocomposites and Their Application in a Controlled Antibacterial Assay. AB - In this work, we report a photosensitizer-loaded hybrid nanostructure that shows high antibacterial efficiency after surface interaction with a lectin protein. Gold nanoparticles were generated on the polymer nanoparticle surface through an in situ reduction method and behaved as a plasmonic amplifier. After conjugation of the photosensitizer rose bengal onto the hybrid nanoparticles, higher phosphorescence intensity and generation of reactive oxygen species (ROS) were observed. The nanocomposites showed high antibacterial efficiency toward Gram negative Escherichia coli treated with a lectin protein concanavalin A, which caused self-assembly of the bacteria and nanoparticles. Therefore, the as prepared nanostructure considerably improved the effectiveness of ROS toward bacteria and provides an alternative strategy for controlled antibacterial assays. PMID- 27700041 TI - Determination of Fragrance Allergens by Ultraviolet Femtosecond Laser Ionization Mass Spectrometry. AB - The allergenic compounds listed in the Cosmetics Directive by the Scientific Committee for Consumer Safety were analyzed by gas chromatography combined with multiphoton ionization mass spectrometry using a femtosecond laser emitting at 200 and 267 nm as the ionization source. The limits of detection were less than 100 pg/MUL for all of the compounds, permitting them to be measured in actual samples that were simply prepared by a 100-fold dilution of the original sample. The ionization process was investigated for the 26 allergens, some of which had no absorption band, even in the far-UV region. As a result, nonresonant two photon ionization was found to be the most sensitive and universal method for the trace analysis of these compounds, because of the short pulse width, i.e., a high peak power, of the femtosecond laser used. It should be noted that the excess energy can be reduced by using a laser emitting at longer wavelengths (267 nm) and that fragmentation can be suppressed, especially for a molecule that contains a long side chain. Three commercially available perfumes were measured, and more than 10 allergenic compounds were determined. PMID- 27700043 TI - Triboelectricity Generation from Vertically Aligned Carbon Nanotube Arrays. AB - We explore the use of vertically aligned carbon nanotube (VACNT) arrays as an electrode in a triboelectric nanogenerator (TENG) that harvests mechanical energy and converts it to electrical energy. When VACNT arrays, 1 cm2 in area, are mechanically contacted with PET and PTFE counter electrodes in vertical contact separation mode, currents up to 0.16 uA and 0.21 uA, and voltages up to 1.42 V and 3.20 V are obtained, respectively. The VACNT TENG output remains stable even after over 20,000 continuous contact cycles. A 0.47 uF capacitor is successfully charged to 4.5 V in 60 s using a VACNT-PTFE triboelectric nanogenerator (TENG) prototype. PMID- 27700042 TI - Protein-Metal Organic Framework Hybrid Composites with Intrinsic Peroxidase-like Activity as a Colorimetric Biosensing Platform. AB - Artificial enzyme mimetics have received considerable attention because natural enzymes have some significant drawbacks, including enzyme autolysis, low catalytic activity, poor recovery, and low stability to environmental changes. Herein, we demonstrated a facile approach for one-pot synthesis of hemeprotein metal organic framework hybrid composites (H-MOFs) by using bovine hemoglobin (BHb) and zeolitic imidazolate framework-8 (ZIF-8) as a model reaction system. Surprisingly, the new hybrid composites exhibit 423% increase in peroxidase-like catalytic activity compared to free BHb. Taking advantages of the unique pore structure of H-MOFs with high catalytic property, a H-MOFs-based colorimetric biosensing platform was newly constructed and applied for the fast and sensitive detection of hydrogen peroxide (H2O2) and phenol. The corresponding detection limits as low as 1.0 MUM for each analyte with wide linear ranges (0-800 MUM for H2O2 and 0-200 MUM for phenol) were obtained by naked-eye visualization. Significantly, a sensitive and selective method for visual assay of trace H2O2 in cells and phenol in sewage was achieved with this platform. The stability of H MOFs was also examined, and excellent reproducibility and recyclability without losing in their activity were observed. In addition, the general applicability of H-MOFs was also investigated by using other hemeproteins (horseradish peroxidase, and myoglobin), and the corresponding catalytic activities were 291% and 273% enhancement, respectively. This present work not only expands the application of MOFs but also provides an alternative technique for biological and environmental sample assay. PMID- 27700044 TI - Yolk-Shell Ni@SnO2 Composites with a Designable Interspace To Improve the Electromagnetic Wave Absorption Properties. AB - In this study, yolk-shell Ni@SnO2 composites with a designable interspace were successfully prepared by the simple acid etching hydrothermal method. The Ni@void@SnO2 composites were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, and transmission electron microscopy. The results indicate that interspaces exist between the Ni cores and SnO2 shells. Moreover, the void can be adjusted by controlling the hydrothermal reaction time. The unique yolk shell Ni@void@SnO2 composites show outstanding electromagnetic wave absorption properties. A minimum reflection loss (RLmin) of -50.2 dB was obtained at 17.4 GHz with absorber thickness of 1.5 mm. In addition, considering the absorber thickness, minimal reflection loss, and effective bandwidth, a novel method to judge the effective microwave absorption properties is proposed. On the basis of this method, the best microwave absorption properties were obtained with a 1.7 mm thick absorber layer (RLmin= -29.7 dB, bandwidth of 4.8 GHz). The outstanding electromagnetic wave absorption properties stem from the unique yolk-shell structure. These yolk-shell structures can tune the dielectric properties of the Ni@air@SnO2 composite to achieve good impedance matching. Moreover, the designable interspace can induce interfacial polarization, multiple reflections, and microwave plasma. PMID- 27700045 TI - Specific Detection of Cellular Glutamine Hydrolysis in Live Cells Using HNCO Triple Resonance NMR. AB - Glutamine plays key roles as a biosynthetic precursor or an energy source in cancers, and interest in its metabolism is rapidly growing. However, the proper evaluation of glutamine hydrolysis, the very first reaction in the entire glutaminolysis, has been difficult. Here, we report a triple resonance NMR-based assay for specific detection of glutaminase activity carrying out this reaction using stable-isotope labeled glutamine. Compared to conventional methods involving coupled enzyme assays, the proposed approach is direct because it detects the presence of the H-N-CO amide spin system. In addition, the method is unique in enabling the measurement of glutamine hydrolysis reaction in real-time in live cells. The approach was applied to investigating the effects of a glutaminase inhibitor and the inhibitory effects of glucose on glutamine metabolism in live cells. It can be easily applied to studying other signals that affect cellular glutamine metabolism. PMID- 27700046 TI - Laser-Assisted Focused He+ Ion Beam Induced Etching with and without XeF2 Gas Assist. AB - Focused helium ion (He+) milling has been demonstrated as a high-resolution nanopatterning technique; however, it can be limited by its low sputter yield as well as the introduction of undesired subsurface damage. Here, we introduce pulsed laser- and gas-assisted processes to enhance the material removal rate and patterning fidelity. A pulsed laser-assisted He+ milling process is shown to enable high-resolution milling of titanium while reducing subsurface damage in situ. Gas-assisted focused ion beam induced etching (FIBIE) of Ti is also demonstrated in which the XeF2 precursor provides a chemical assist for enhanced material removal rate. Finally, a pulsed laser-assisted and gas-assisted FIBIE process is shown to increase the etch yield by ~9* relative to the pure He+ sputtering process. These He+ induced nanopatterning techniques improve material removal rate, in comparison to standard He+ sputtering, while simultaneously decreasing subsurface damage, thus extending the applicability of the He+ probe as a nanopattering tool. PMID- 27700047 TI - Polymer Colloidal Sphere-Based Hybrid Solid Immersion Lens for Optical Super Resolution Imaging. AB - Optical microscope is widely used real-time investigation tool, but usually suffers from low resolution due to Abbe diffraction limit. Herein, we design and successfully synthesize ZrO2/polymer hybrid colloidal microspheres with as high as 47.5 wt% inorganic nanoparticles by suspension polymerization of 9,9'-bis[4-(2 acryloyloxyethyloxy) phenyl] fluorene (BAEPF). Owing to the homogeneous dispersion, high density and high refractive index of inorganic nanoparticles and deformability of polymer, the obtained ZrO2/poly(BAEPF) hybrid colloidal microspheres have high refractive index, optical transparency and controllable curvature, and thus can be directly used as a hybrid solid immersion lens (hSIL) for optical microscope, achieving super-resolution imaging of 50 nm even 45 nm under a standard white light or blue light optical microscopes, which is far beyond the diffraction limit for visible light optical microscopes. Our hSIL design concept and strategy demonstrate efficient, fast and solid practical potentials for optical super-resolution imaging, and may also create another application possibility for polymer colloidal spheres. PMID- 27700048 TI - Growth of One-Dimensional RuO2 Nanowires on g-Carbon Nitride: An Active and Stable Bifunctional Electrocatalyst for Hydrogen and Oxygen Evolution Reactions at All pH Values. AB - Development of highly efficient and durable bifunctional electrocatalyst for hydrogen and oxygen evolution reactions (HER and OER) is essential for efficient solar fuel generation. The commercial RuO2 or RuO2-based catalysts are highly active toward OER, but their poor stability under different operating conditions is the main obstacle for their commercialization. Herein, we report growth of one dimensional highly crystalline RuO2 nanowires on carbon nitride (1D-RuO2-CNx) for their applications in HER and OER at all pH values. The 1D-RuO2-CNx, as an OER catalyst, exhibits a low onset overpotential of ~200 mV in both acidic and basic media, whereas Tafel slopes are 52 and 56 mV/dec in acidic and basic media, respectively. This catalyst requires a low overpotential of 250 and 260 mV to drive the current density of 10 mA cm-2 in acidic and basic media, respectively. The mass activity of 1D-RuO2-CNx catalyst is 352 mA mg-1, which is ~14 times higher than that of commercial RuO2. Most importantly, the 1D-RuO2-CNx catalyst has remarkably higher stability compared to commercial RuO2. This catalyst also exhibits superior HER activity with a current density of 10 mAcm-2 at ~93 and 95 mV in acidic and basic media. The HER Tafel slopes of this catalyst are 40 mV/dec in acidic condition and 70 mV/dec in basic condition. The HER activity of this catalyst is slightly lower than Pt/C in acidic media, whereas in basic media it is comparable or even better than that of Pt/C at higher overpotentials. The HER stability of this catalyst is also better than that of Pt/C in all pH solutions. This superior catalytic activity of 1D-RuO2-CNx composite can be attributed to catalyst-support interaction, enhanced mass and electron transport, one dimensional morphology, and highly crystalline rutile RuO2 structure. PMID- 27700050 TI - Approaches to Study Phosphatases. AB - Phosphatases play key roles in normal physiology and diseases. Studying phosphatases has been both essential and challenging, and the application of conventional genetic and biochemical methods has led to crucial but still limited understanding of their mechanisms, substrates, and exclusive functions within highly intricate networks. With the advances in technologies such as cellular imaging and molecular and chemical biology in terms of sensitive tools and methods, the phosphatase field has thrived in the past years and has set new insights for cell signaling studies and for therapeutic development. In this review, we give an overview of the existing interdisciplinary tools for phosphatases, give examples on how they have been applied to increase our understanding of these enzymes, and suggest how they-and other tools yet barely used in the phosphatase field-might be adapted to address future questions and challenges.

AB - In hybrid organic-inorganic perovskite solar cells (PSCs), interfacial engineering can efficiently improve the photovoltaic performance. In this work, the planar pi-conjugated porphyrin, zinc(II) 5,10,15,20-tetrakis[5-(p acetylthiopentyloxy)phenyl]porphyrin, was developed to modify the interface between poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic acid) (PEDOT:PSS) and perovskite. The modified devices increased their highest power conversion efficiency (PCE) to 14.05% relative to 11.35% for the reference devices without modification. Such enhancement in efficiency is mainly attributed to the improved open-circuit voltage (Voc) and fill factor (FF), which benefit from fast hole extraction and low charge recombination after the employment of well-aligned interlayer. PMID- 27700049 TI - Pharmacodynamic Relationships between Duration of Action of JDTic-like Kappa Opioid Receptor Antagonists and Their Brain and Plasma Pharmacokinetics in Rats. AB - JDTic is a potent and selective kappa-opioid receptor (KOR) antagonist that reverses U50,488-induced diuresis in rats. It partitions into brain with a duration of action lasting for weeks. In a search for KOR antagonists that do not accumulate in the brain, we compared single doses of five methylated JDTic analogs (RTI-97, -194, -212, -240, and -241) for reversal of U50,488 diuresis and pharmacokinetic (PK) properties. All six compounds showed potent and selective KOR antagonism in a [35S]GTPgammaS binding assay. Plasma half-lives ranged from 24 to 41 h and brain half-lives from 24 to 76 h. JDTic and RTI-194 showed increasing brain to plasma ratios over time, indicating increasing partitioning into brain and a longer duration of action for reversal of diuresis than did RTI 97. RTI-240 did not show significant brain accumulation. RTI-212 showed no substantive difference between brain and plasma levels and was inactive against diuresis. RTI-241, with a lower brain to plasma ratio than JDTic and RTI-194, formed JDTic as a metabolite, which still reduced diuresis after 9 weeks. The fact that the duration of action was correlated with the brain to blood plasma ratios and area under the concentration-time curves suggests that PK properties could help to predict safety and acceptable duration of action for KOR antagonists.

AB - Double perovskites (DP) of the general formula Ba2MReO6, where M = Mg, Zn, and Y2/3, all based on Re6+ (5d1, t2g1), were synthesized and studied using magnetization, heat capacity, muon spin relaxation, and neutron-scattering techniques. All are cubic, Fm3m, at ambient temperature to within the resolution of the X-ray and neutron diffraction data, although the muon data suggest the possibility of a local distortion for M = Mg. The M = Mg DP is a ferromagnet, Tc = 18 K, with a saturation moment ~0.3 bohr magnetons at 3 K. There are two anomalies in the heat capacity: a sharp feature at 18 K and a broad maximum centered near 33 K. The total entropy loss below 45 K is 9.68 e.u., which approaches R ln 4 (11.52 e.u.) supporting a j = 3/2 ground state. The unit cell constants of Ba2MgReO6 and the isostructural, isoelectronic analogue, Ba2LiOsO6, differ by only 0.1%, yet the latter is an anti-ferromagnet. The M = Zn DP also appears to be a ferromagnet, Tc = 11 K, MUsat(Re) = 0.1 MUB. In this case the heat capacity shows a somewhat broad peak near 10 K and a broader maximum at ~33 K, behavior that can be traced to a smaller particle size, ~30 nm, for this sample. For both M = Mg and Zn, the low-temperature magnetic heat capacity follows a T3/2 behavior, consistent with a ferromagnetic spin wave. An attempt to attribute the broad 33 K heat capacity anomalies to a splitting of the j = 3/2 state by a crystal distortion is not supported by inelastic neutron scattering, which shows no transition at the expected energy of ~7 meV nor any transition up to 100 meV. However, the results for the two ferromagnets are compared to the theory of Chen, Pereira, and Balents, and the computed heat capacity predicts the two maxima observed experimentally. The M = Y2/3 DP, with a significantly larger cell constant (3%) than the ferromagnets, shows predominantly anti-ferromagnetic correlations, and the ground state is complex with a spin frozen component Tg = 16 K from both direct current and alternating current susceptibility and MUSR data but with a persistent dynamic component. The low-temperature heat capacity shows a T1 power law. The unit cell constant of B = Y2/3 is less than 1% larger than that of the ferromagnetic Os7+ (5d1) DP, Ba2NaOsO6.

AB - We demonstrate metabolic enzyme ligation using a transpeptidase (Staphylococcal sortase A) in the microbial cytoplasm for the redirection of metabolic flux through metabolic channeling. Here, sortase A expression was controlled by the lac promoter to trigger metabolic channeling by the addition of isopropyl-beta-d thiogalactopyranoside (IPTG). We tested covalent linking of pyruvate-formate lyase and phosphate acetyltransferase by sortase A-mediated ligation and evaluated the production of acetate. The time point of addition of IPTG was not critical for facilitating metabolic enzyme ligation, and acetate production increased upon expression of sortase A. These results show that sortase A mediated enzyme ligation enhances an acetate-producing flux in E. coli. We have validated that sortase A-mediated enzyme ligation offers a metabolic channeling approach to redirect a central flux to a desired flux. PMID- 27700054 TI - Electron Transfer and Solvent-Mediated Electronic Localization in Molecular Photocatalysis. AB - This work provides a detailed mechanism for electron transfer in a heterodinuclear complex designed as a model system in which to study homogeneous molecular photocatalysis. With efficient Born-Oppenheimer molecular dynamics simulations, we show how intermediate, charge-separated states can mediate the electron transfer. We observe how Jahn-Teller distortion effects play out in solution, when the molecule has energetically close-lying states, and how this distortion is averaged out in the thermal sampling. Finally, we demonstrate how the solvent helps stabilize and localize the separated charge. The information on the electronic configuration and separate states is of key importance for designing next-generation photocatalysts.

AB - Genome editing using CRISPR/Cas9 was successfully demonstrated in Esherichia coli to effectively produce n-butanol in a defined medium under microaerobic condition. The butanol synthetic pathway genes including those encoding oxygen tolerant alcohol dehydrogenase were overexpressed in metabolically engineered E. coli, resulting in 0.82 g/L butanol production. To increase butanol production, carbon flux from acetyl-CoA to citric acid cycle should be redirected to acetoacetyl-CoA. For this purpose, the 5'-untranslated region sequence of gltA encoding citrate synthase was designed using an expression prediction program, UTR designer, and modified using the CRISPR/Cas9 genome editing method to reduce its expression level. E. coli strains with decreased citrate synthase expression produced more butanol and the citrate synthase activity was correlated with butanol production. These results demonstrate that redistributing carbon flux using genome editing is an efficient engineering tool for metabolite overproduction.

AB - Studies investigating the effect of carbon nanotubes (CNTs) on the bioavailability and toxicity of hydrophobic organic compounds in aquatic environments have generated contradictory results, and the influence of different CNT properties remains unknown. Here, the adsorption of the polycyclic aromatic hydrocarbon phenanthrene (70-735 MUg/L) to five types of CNTs exhibiting different physical and chemical properties was studied. The CNTs were dispersed in the presence of natural organic matter (nominally 20 mg/L) in order to increase the environmental relevance of the study. Furthermore, the bioavailability and toxicity of phenanthrene to Daphnia magna in the absence and presence of dispersed CNTs was investigated. Both CNT dispersion and adsorption of phenanthrene appeared to be influenced by CNT physical properties (diameter and specific surface area). However, dispersion and phenanthrene adsorption was not influenced by CNT surface chemical properties (surface oxygen content), under the conditions tested. Based on nominal phenanthrene concentrations, a reduction in toxicity to D. magna was observed during coexposure to phenanthrene and two types of CNTs, while for the others, no influence on phenanthrene toxicity was observed. Based on freely dissolved concentrations, however, an increased toxicity was observed in the presence of all CNTs, indicating bioavailability of CNT-adsorbed phenanthrene to D. magna.

AB - This study examines size-resolved physicochemical data for particles sampled near mining and smelting operations and a background urban site in Arizona with a focus on how hygroscopic growth impacts particle deposition behavior. Particles with aerodynamic diameters between 0.056-18 MUm were collected at three sites: (i) an active smelter operation in Hayden, AZ, (ii) a legacy mining site with extensive mine tailings in Iron King, AZ, and (iii) an urban site, inner-city Tucson, AZ. Mass size distributions of As and Pb exhibit bimodal profiles with a dominant peak between 0.32 and 0.56 MUm and a smaller mode in the coarse range (>3 MUm). The hygroscopicity profile did not exhibit the same peaks owing to dependence on other chemical constituents. Submicrometer particles were generally more hygroscopic than supermicrometer ones at all three sites with finite water uptake ability at all sites and particle sizes examined. Model calculations at a relative humidity of 99.5% reveal significant respiratory system particle deposition enhancements at sizes with the largest concentrations of toxic contaminants. Between dry diameters of 0.32 and 0.56 MUm, for instance, ICRP and MPPD models predict deposition fraction enhancements of 171%-261% and 33%-63%, respectively, at the three sites. PMID- 27700058 TI - The Rate of Crude Oil Biodegradation in the Sea. AB - Various groups have studied the rate of oil biodegradation in the sea over many years, but with no consensus on results. This can be attributed to many factors, but we show here that the principal confounding influence is the concentration of oil used in different experiments. Because of dilution, measured concentrations of dispersed oil in the sea are sub-parts-per-million within a day of dispersal, and at such concentrations the rate of biodegradation of detectable oil hydrocarbons has an apparent half-life of 7-14 days. This can be contrasted with the rate of degradation at the higher concentrations found in oil slicks or when stranded on a shoreline; there the apparent half-life varies from many months to many years. PMID- 27700059 TI - Rationally Designed Redox-Sensitive Protein Hydrogels with Tunable Mechanical Properties. AB - Protein hydrogels are an important class of materials for applications in biotechnology and medicine. The fine-tuning of their sequence, molecular weight, and stereochemistry offers unique opportunities to engineer biofunctionality, biocompatibility, and biodegradability into these materials. Here we report a new family of redox-sensitive protein hydrogels with controllable mechanical properties composed of recombinant silk-elastin-like protein polymers (SELPs). The SELPs were designed and synthesized with different ratios of silk-to-elastin blocks that incorporated periodic cysteine residues. The cysteine-containing SELPs were thermally responsive in solution and rapidly formed hydrogels at body temperature under physiologically relevant, mild oxidative conditions. Upon addition of a low concentration of hydrogen peroxide at 0.05% (w/v), gelation occurred within minutes for the SELPs with a protein concentration of approximately 4% (w/v). The gelation time and mechanical properties of the hydrogels were dependent on the ratio of silk to elastin. These polymer designs also significantly affected redox-sensitive release of a highly polar model drug from the hydrogels in vitro. Furthermore, oxidative gelation was performed at other physiologically relevant temperatures, and this resulted in hydrogels with tunable mechanical properties, thus, providing a secondary level of control over hydrogel stiffness. These newly developed injectable SELP hydrogels with redox sensitive features and tunable mechanical properties may be potentially useful as biomaterials with broad applications in controlled drug delivery and tissue engineering. PMID- 27700061 TI - Ditechnetium Heptoxide Revisited: Solid-State, Gas-Phase, and Theoretical Studies. AB - Ditechnetium heptoxide was synthesized from the oxidation of TcO2 with O2 at 450 degrees C and characterized by single-crystal X-ray diffraction, electron-impact mass spectrometry (EI-MS), and theoretical methods. Refinement of the structure at 100 K indicates that Tc2O7 crystallizes as a molecular solid in the orthorhombic space group Pbca [a = 7.312(3) A, b = 5.562(2) A, c = 13.707(5) A, and V = 557.5(3) A3]. The Tc2O7 molecule can be described as corner-sharing TcO4 tetrahedron [Tc---Tc = 3.698(1) A and Tc-OBri-Tc = 180.0 degrees ]. The EI-MS spectrum of Tc2O7 consists of both mononuclear and dinuclear species. The main dinuclear species in the gas-phase are Tc2O7 (100%) and Tc2O5 (56%), while the main mononuclear species are TcO3 (33.9%) and TcO2 (42.8%). The difference in the relative intensities of the M2O5 (M = Tc, Re) fragments (1.7% for Re) indicates that these group 7 elements exhibit different gas-phase chemistry. The solid state structure of Tc2O7 was investigated by density functional theory methods. The optimized structure of the Tc2O7 molecule is in good agreement with the experimental one. Simulations indicate that the more favorable geometry for the Tc2O7 molecule in the gas-phase is bent (Tc-OBri-Tc = 156.5 degrees ), while a linear geometry (Tc-OBri-Tc = 180.0 degrees ) is favored in the solid-state. PMID- 27700060 TI - Oxidizing Impact Induced by Mackinawite (FeS) Nanoparticles at Oxic Conditions due to Production of Hydroxyl Radicals. AB - Mackinawite (FeS) nanoparticles have been extensively tested for reducing contaminants under anoxic conditions, while the oxidizing impact induced by FeS under oxic conditions has been largely underestimated. In light of previous findings that hydroxyl radicals (.OH) can be produced from oxygenation of sediment Fe(II), herein we revealed that .OH can be produced efficiently from FeS oxygenation at circumneutral conditions, yielding 84.7 MUmol .OH per g FeS. Much more .OH was produced from the oxygenation of FeS compared with siderite, pyrite, and zerovalent iron nanoparticles under the same conditions. The oxidation of FeS was a surface-mediated process, in which O2 was transformed by the structural Fe(II) on FeS surface to .OH with the generation of H2O2 intermediate. A small proportion of Fe(II) was regenerated from the reduction of Fe(III) by FeS and S( II), but this proportion did not significantly contribute to .OH production. We further validated that the .OH produced from FeS oxygenation considerably contributed to the oxidation of arsenic. As the change of redox conditions from anoxic to oxic is common in both natural and artificial processes, our findings suggest that the oxidizing impact induced by FeS at oxic conditions should be concerned due to .OH production.

AB - Photobleaching is a major obstacle in the real-time imaging of biological events, particularly at the single-molecule/particle level. Here, we report a strategy to delay photobleaching of a light-switch complex, [Ru(phen)2dppx]2+, by insertion of a six-cysteine peptide into virus particles. The six-cysteine peptide was inserted into viral protein R of HIV-1 and assembled into infectious HIV-1 viral particles, where it effectively delayed the photobleaching of the [Ru(phen)2dppx]2+ complex used to label viral genomic RNAs. This delay in photobleaching allowed for a monofluorescent assay to be constructed for the real time monitoring of viral uncoating, a poorly understood process. This novel strategy to delay photobleaching in infectious viral particles provides a powerful method to analyze viral uncoating at the single-particle level in real time. PMID- 27700064 TI - Protein kinase C Signaling in Adenoviral Infection. AB - Activation of protein kinase C (PKC), a serine/threonine protein kinase, ubiquitously influences cellular signal transduction, and has been shown to play a role in viral entry. In this study, we explored a role for PKC in human adenovirus type 37 infection of primary human corneal fibroblasts, a major target cell for infection. We sought evidence for an interaction between PKC activation and two potential downstream targets: cSrc kinase, shown previously to play a critical role in adenovirus signaling in these cells, and caveolin-1, reported earlier to be important to entry of adenovirus type 37. Infection of fibroblasts increased PKCalpha phosphorylation and translocation of PKCalpha from the cytosol to caveolin-1 containing vesicles. Virus-induced phosphorylation of both cSrc and AKT was abolished in cell lysates pretreated with calphostin C, a chemical inhibitor of PKC. Inhibition of PKC also reduced virus associated phosphorylation of caveolin-1, while inhibition of cSrc by the chemical inhibitor PP2 reduced only caveolin-1 phosphorylation, but not PKCalpha phosphorylation, in lipid rafts. These results suggest a role for PKCalpha upstream to both cSrc and caveolin-1. Phosphorylated PKCalpha was found in the same endosomal fractions as phosphorylated cSrc, and PKCalpha was present to a greater degree in caveolin-1 pull downs from virus infected than mock infected cell lysates. Calphostin C also reduced early viral gene expression, indicating that PKCalpha activity may be required for viral entry. PKCalpha plays a central role in adenovirus infection of corneal fibroblasts and regulation of downstream molecules, including the important lipid raft component caveolin-1. PMID- 27700066 TI - Comparison of Atmospheric Pressure Chemical Ionization and Field Ionization Mass Spectrometry for the Analysis of Large Saturated Hydrocarbons. AB - Direct infusion atmospheric pressure chemical ionization mass spectrometry (APCI MS) was compared to field ionization mass spectrometry (FI-MS) for the determination of hydrocarbon class distributions in lubricant base oils. When positive ion mode APCI with oxygen as the ion source gas was employed to ionize saturated hydrocarbon model compounds (M) in hexane, only stable [M - H]+ ions were produced. Ion-molecule reaction studies performed in a linear quadrupole ion trap suggested that fragment ions of ionized hexane can ionize saturated hydrocarbons via hydride abstraction with minimal fragmentation. Hence, APCI-MS shows potential as an alternative of FI-MS in lubricant base oil analysis. Indeed, the APCI-MS method gave similar average molecular weights and hydrocarbon class distributions as FI-MS for three lubricant base oils. However, the reproducibility of APCI-MS method was found to be substantially better than for FI-MS. The paraffinic content determined using the APCI-MS and FI-MS methods for the base oils was similar. The average number of carbons in paraffinic chains followed the same increasing trend from low viscosity to high viscosity base oils for the two methods. PMID- 27700067 TI - Stability of Superhalogen Anions in the Aqueous Phase. AB - The issue of stability of superhalogen anions in an aqueous solution is investigated on the basis of theoretical calculations carried out at the CCSD(T)/6-311++G(d,p)//MP2/6-311++G(d,p) level for two representative negatively charged systems (NaF2- and AlF4-) whose fragmentation products differ in polarity. The presence of a water solvent is simulated independently by employing the polarized continuum solvation model and by involving eight H2O molecules explicitly to allow interactions at the molecular level. The best estimates of the Gibbs free energies characterizing the AlF4- and NaF2- fragmentation reactions in a water solvent are evaluated as equal to 33-34 and 12-14 kcal/mol, respectively (assuming the F- and AlF3/NaF products) or 14-15 and 26-28 kcal/mol, respectively (assuming the HF and AlF3OH-/NaFOH- products). The corresponding fragmentation routes are suggested to be nonoperative at T = 298.15 K. The conclusion concerning the thermodynamic stability of the AlF4- and NaF2- superhalogen anions in the aqueous phase is formulated and discussed. PMID- 27700065 TI - Imaging Taurine in the Central Nervous System Using Chemically Specific X-ray Fluorescence Imaging at the Sulfur K-Edge. AB - A method to image taurine distributions within the central nervous system and other organs has long been sought. Since taurine is small and mobile, it cannot be chemically "tagged" and imaged using conventional immuno-histochemistry methods. Combining numerous indirect measurements, taurine is known to play critical roles in brain function during health and disease and is proposed to act as a neuro-osmolyte, neuro-modulator, and possibly a neuro-transmitter. Elucidation of taurine's neurochemical roles and importance would be substantially enhanced by a direct method to visualize alterations, due to physiological and pathological events in the brain, in the local concentration of taurine at or near cellular spatial resolution in vivo or in situ in tissue sections. We thus have developed chemically specific X-ray fluorescence imaging (XFI) at the sulfur K-edge to image the sulfonate group in taurine in situ in ex vivo tissue sections. To our knowledge, this represents the first undistorted imaging of taurine distribution in brain at 20 MUm resolution. We report quantitative technique validation by imaging taurine in the cerebellum and hippocampus regions of the rat brain. Further, we apply the technique to image taurine loss from the vulnerable CA1 (cornus ammonis 1) sector of the rat hippocampus following global brain ischemia. The location-specific loss of taurine from CA1 but not CA3 neurons following ischemia reveals osmotic stress may be a key factor in delayed neurodegeneration after a cerebral ischemic insult and highlights the significant potential of chemically specific XFI to study the role of taurine in brain disease. PMID- 27700068 TI - Site Occupancies, Luminescence, and Thermometric Properties of LiY9(SiO4)6O2:Ce3+ Phosphors. AB - In this work, we report the tunable emission properties of Ce3+ in an apatite type LiY9(SiO4)6O2 compound via adjusting the doping concentration or temperature. The occupancies of Ce3+ ions at two different sites (Wyckoff 6h and 4f sites) in LiY9(SiO4)6O2 have been determined by Rietveld refinements. Two kinds of Ce3+ f-d transitions have been studied in detail and then assigned to certain sites. The effects of temperature and doping concentration on Ce3+ luminescence properties have been systematically investigated. It is found that the Ce3+ ions prefer occupying Wyckoff 6h sites and the energy transfer between Ce3+ at two sites becomes more efficient with an increase in doping concentration. In addition, the charge-transfer vibronic exciton (CTVE) induced by the existence of free oxygen ion plays an important role in the thermal quenching of Ce3+ at 6h sites. Because of the tunable emissions from cyan to blue with increasing temperature, the phosphors LiY9(SiO4)6O2:Ce3+ are endowed with possible thermometric applications.

AB - Five new lignan glycosides, wasabisides A-E (1-5), and four known phenolic compounds (6-9), were isolated from the roots of Wasabia japonica. The chemical structures of the new compounds (1-5) were determined through spectroscopic analysis and chemical methods. All isolated compounds (1-9) were evaluated for their potential neuroprotective effects through induction of nerve growth factor in C6 glioma cells, for their effects on nitric oxide levels in lipopolysaccharide-stimulated murine microglia BV2 cells, and for their cytotoxicity against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, and BT549). PMID- 27700069 TI - Environmental Chemicals in an Urban Population of Pregnant Women and Their Newborns from San Francisco. AB - Exposures to environmental pollutants in utero may increase the risk of adverse health effects. We measured the concentrations of 59 potentially harmful chemicals in 77 maternal and 65 paired umbilical cord blood samples collected in San Francisco during 2010-2011, including polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), polybrominated diphenyl ethers (PBDEs), hydroxylated PBDEs (OH-PBDEs), and perfluorinated compounds (PFCs) in serum and metals in whole blood. Consistent with previous studies, we found evidence that concentrations of mercury (Hg) and lower-brominated PBDEs were often higher in umbilical cord blood or serum than in maternal samples (median cord:maternal ratio > 1), while for most PFCs and lead (Pb), concentrations in cord blood or serum were generally equal to or lower than their maternal pair (median cord:maternal ratio <= 1). In contrast to the conclusions of a recent review, we found evidence that several PCBs and OCPs were also often higher in cord than maternal serum (median cord:maternal ratio > 1) when concentrations are assessed on a lipid-adjusted basis. Our findings suggest that for many chemicals, fetuses may experience higher exposures than their mothers and highlight the need to characterize potential health risks and inform policies aimed at reducing sources of exposure. PMID- 27700072 TI - Effect of Oral Administration of 3,3'-Diindolylmethane on Dextran Sodium Sulfate Induced Acute Colitis in Mice. AB - In patients with inflammatory bowel disease (IBD), inflammation is induced and maintained by lymphangiogenesis and angiogenesis. 3,3'-Diindolylmethane (DIM) is a natural product formed in acidic conditions from indole-3-carbinol in cruciferous vegetables, and it is known for its chemotherapeutic activity. This study evaluated DIM's effects on angiogenesis, lymphangiogenesis, and inflammation in a mouse colitis model. Experimental colitis was induced in mice by administering 3% dextran sulfate sodium (DSS) via drinking water. DIM remarkably attenuated the clinical signs and histological characteristics in mice with DSS-induced colitis. DIM suppressed neutrophil infiltration and pro inflammatory cytokines. Moreover, it significantly suppressed the expression of vascular endothelial growth factor (VEGF)-A and VEGF receptor (VEGFR)-2, indicating that the mechanism may be related to the repression of pro angiogenesis activity. DIM also remarkably suppressed the expression of VEGF-C, VEGF-D, VEGFR-3, and angiopoietin-2; thus, the mechanism may also be related to the suppression of lymphangiogenesis. Therefore, DIM is a possible treatment option for inflammation of the intestine and associated angiogenesis and lymphangiogenesis.

PMID- 27700071 TI - Biosynthetic Timing and Substrate Specificity for the Thiopeptide Thiomuracin. AB - The biosynthesis of the thiopeptide thiomuracin is a well-orchestrated process involving a multitude of posttranslational modifications. We show that six Cys residues of a precursor peptide are first cyclodehydrated and oxidized to thiazoles in an ordered, but nonlinear fashion that is leader-peptide-dependent. Then four alcohols are glutamylated and converted to alkenes in a C-to-N terminal directional process that is leader-peptide-independent. Finally, two of these alkenes undergo a formal [4 + 2] cycloaddition to form a trithiazole-substituted pyridine macrocycle. We describe here the factors that govern the substrate specificity and order of biosynthetic events that turn a ribosomal peptide into a powerful antibiotic. PMID- 27700075 TI - Optimized DNA "Nanosuitcases" for Encapsulation and Conditional Release of siRNA. AB - We set out to design, synthesize and optimize a DNA-minimal cage capable of encapsulating oligonucleotide drugs to facilitate their delivery. Through rational design and optimization using in vitro assays, we have assembled the first DNA "nanosuitcase" that can encapsulate a siRNA construct and release it upon recognition of an oligonucleotide trigger. The latter may be a messenger RNA (mRNA) or a microRNA (miRNA) which offers potential for dual or synergistic therapy. This construct assembles in near 100% yield, releases its cargo on demand and can sustain biological conditions. Moreover, we find that the DNA scaffold is able to protect its cargo against site-specific cleavage and nuclease degradation. Release of the cargo is performed with fixed cells using a FRET enabled construct imaged by confocal microscopy and reveals that the DNA cage remains responsive at the molecular level in a complex cellular environment. We foresee this construct will be able to address challenges in drug delivery, more specifically in non-toxic delivery and targeted release. PMID- 27700074 TI - The Quest for Converting Biorenewable Bifunctional alpha-Methylene-gamma butyrolactone into Degradable and Recyclable Polyester: Controlling Vinyl Addition/Ring-Opening/Cross-Linking Pathways. AB - alpha-Methylene-gamma-butyrolactone (MBL), a naturally occurring and biomass sourced bifunctional monomer, contains both a highly reactive exocyclic C?C bond and a highly stable five-membered gamma-butyrolactone ring. Thus, all previous work led to exclusive vinyl-addition polymerization (VAP) product P(MBL)VAP. Now, this work reverses this conventional chemoselectivity to enable the first ring opening polymerization (ROP) of MBL, thereby producing exclusively unsaturated polyester P(MBL)ROP with Mn up to 21.0 kg/mol. This elusive goal was achieved through uncovering the thermodynamic, catalytic, and processing conditions. A third reaction pathway has also been discovered, which is a crossover propagation between VAP and ROP processes, thus affording cross-linked polymer P(MBL)CLP. The formation of the three types of polymers, P(MBL)VAP, P(MBL)CLP, and P(MBL)ROP, can be readily controlled by adjusting the catalyst (La)/initiator (ROH) ratio, which is determined by the unique chemoselectivity of the La-X (X = OR, NR2, R) group. The resulting P(MBL)ROP is degradable and can be readily postfunctionalized into cross-linked or thiolated materials but, more remarkably, can also be fully recycled back to its monomer thermochemically. Computational studies provided the theoretical basis for, and a mechanistic understanding of, the three different polymerization processes and the origin of the chemoselectivity. PMID- 27700076 TI - Stereoselective Synthesis of Methylene Oxindoles via Palladium(II)-Catalyzed Intramolecular Cross-Coupling of Carbamoyl Chlorides. AB - We report a highly robust, general and stereoselective method for the synthesis of 3-(chloromethylene)oxindoles from alkyne-tethered carbamoyl chlorides using PdCl2(PhCN)2 as the catalyst. The transformation involves a stereo- and regioselective chloropalladation of an internal alkyne to generate a nucleophilic vinyl PdII species, which then undergoes an intramolecular cross-coupling with a carbamoyl chloride. The reaction proceeds under mild conditions, is insensitive to the presence of moisture and air, and is readily scalable. The products obtained from this reaction are formed with >95:5 Z:E selectivity in nearly all cases and can be used to access biologically relevant oxindole cores. Through combined experimental and computational studies, we provide insight into stereo- and regioselectivity of the chloropalladation step, as well as the mechanism for the C-C bond forming process. Calculations provide support for a mechanism involving oxidative addition into the carbamoyl chloride bond to generate a high valent PdIV species, which then undergoes facile C-C reductive elimination to form the final product. Overall, the transformation constitutes a formal PdII catalyzed intramolecular alkyne chlorocarbamoylation reaction.

AB - Oligomers of the 42-mer amyloid-beta protein (Abeta42), rather than fibrils, cause synaptic dysfunction in the pathology of Alzheimer's disease (AD). The nucleation phase in a nucleation-dependent aggregation model of Abeta42 is related to the formation of oligomers. Uncaria rhynchophylla is one component of "Yokukansan", a Kampo medicine, which is widely used for treating AD symptoms. Previously, an extract of U. rhynchophylla was found to reduce the aggregation of Abeta42, but its active principles have yet to be identified. In the present work, uncarinic acid C (3) was identified as an inhibitor of Abeta42 aggregation that is present in U. rhynchophylla. Moreover, compound 3 acted as a specific inhibitor of the nucleation phase of Abeta42 aggregation. Compound 3 was synthesized from saponin A (10), an abundant byproduct of rutin purified from Uncaria elliptica. Comprehensive structure-activity studies on 3 suggest that both a C-27 ferulate and a C-28 carboxylic acid group are required for its inhibitory activity. These findings may aid the development of oligomer-specific inhibitors for AD therapy. PMID- 27700078 TI - Neuroprotective Effect of Hydroxytyrosol in Experimental Diabetes Mellitus. AB - The aim of the study was to analyze the possible neuroprotective effect of hydroxytyrosol (HT) in diabetic animals in a model of hypoxia-reoxygenation. Rats (10 animals/group) were distributed in five groups: nondiabetic rats, control diabetic rats (DR), and DR rats treated for 2 months with 1, 5, or 10 mg/kg/day po HT. At the end of follow-up, an experimental model of hypoxia-reoxygenation in brain slices was tested. The DR group showed increased cell death, oxidative and nitrosative stress, and an increase in brain inflammatory mediators. These alterations were significantly greater in DR than in normoglycemic animals. HT significantly reduced oxidative (38.5-52.4% lipid peroxidation) and nitrosative stress (48.0-51.0% nitric oxide and 43.9-75.2% peroxynitrite concentration) and brain inflammatory mediators (18.6-40.6% prostaglandin E2 and 17.0-65.0% interleukin 1beta concentration). Cell death was reduced by 25.9, 37.5, and 41.0% after the administration of 1, 5, or 10 mg/kg/day. The administration of HT in rats with experimental diabetes thus had a neuroprotective effect.

AB - The catalytic fixation of N2 by molecular Fe compounds is a rapidly developing field, yet thus far few complexes can effect this transformation, and none are selective for N2H4 production. Herein we report that the simple Fe(0) complex Fe(Et2PCH2CH2PEt2)2(N2) (1) is an efficient catalyst for the selective conversion of N2 (>25 molecules N2 fixed) into N2H4, attendant with the production of ca. one molecule of NH3. Notably, the reductant (CoCp*2) and acid (Ph2NH2OTf) used are considerably weaker than conventional chemical H+ and e- sources used in previous demonstrations of N2 turnover by synthetic Fe compounds. These results show that the direct catalytic conversion of N2 to the hydrazine oxidation state on molecular Fe complexes is viable and that the mechanism of NH3 formation by such systems may proceed via Fe-N2H4 intermediates.

The method uses a Cu(I) catalyst and an organic percarbonate as the stoichiometric oxidant. The procedure was successfully applied at 0.5 kg scale in the production of a key intermediate in the synthesis of Elbasvir, which is a novel therapy for the treatment of hepatitis C virus infection. PMID- 27700081 TI - Uncovering Single-Molecule Photophysical Heterogeneity of Bright, Thermally Activated Delayed Fluorescence Emitters Dispersed in Glassy Hosts. AB - Recently developed all-organic emitters used in display applications achieve high brightness by harvesting triplet populations via thermally activated delayed fluorescence. The photophysical properties of these emitters therefore involve new inherent complexities and are strongly affected by interactions with their host material in the solid state. Ensemble measurements occlude the molecular details of how host-guest interactions determine fundamental properties such as the essential balance of singlet oscillator strength and triplet harvesting. Therefore, using time-resolved fluorescence spectroscopy, we interrogate these emitters at the single-molecule level and compare their properties in two distinct glassy polymer hosts. We find that nonbonding interactions with aromatic moieties in the host appear to mediate the molecular configurations of the emitters, but also promote nonradiative quenching pathways. We also find substantial heterogeneity in the time-resolved photoluminescence of these emitters, which is dominated by static disorder in the polymer. Finally, since singlet-triplet cycling underpins the mechanism for increased brightness, we present the first room-temperature measurement of singlet-triplet equilibration dynamics in this family of emitters. Our observations present a molecular-scale interrogation of host-guest interactions in a disordered film, with implications for highly efficient organic light-emitting devices. Combining a single-molecule experimental technique with an emitter that is sensitive to triplet dynamics, yet read out via fluorescence, should also provide a complementary approach to performing fundamental studies of glassy materials over a large dynamic range of time scales.

AB - The reaction of cis-[PdCl2(CNXyl)2] (Xyl = 2,6-Me2C6H3) with various 1,3-thiazol- and 1,3,4-thiadiazol-2-amines in chloroform gives a mixture of two regioisomeric binuclear diaminocarbene complexes. For 1,3-thiazol-2-amines the isomeric ratio depends on the reaction conditions and kinetically (KRs) or thermodynamically (TRs) controlled regioisomers were obtained at room temperature and on heating, respectively. In CHCl3 solutions, the isomers are subject to reversible isomerization accompanied with the cleavage of Pd-N and S-N bonds in the carbene fragment XylNCN(R)Xyl. Results of DFT calculations followed by the topological analysis of the electron density distribution within the formalism of Bader's theory (AIM method) reveal that in CHCl3 solution the relative stability of the regioisomers (?Gexp = 1.2 kcal/mol; ?Gcalcd = 3.2 kcal/mol) is determined by the energy difference between two types of the intramolecular chalcogen bonds, viz. S***Cl in KRs (2.8-3.0 kcal/mol) and S***N in TRs (4.6-5.3 kcal/mol). In the case of the 1,3,4-thiadiazol-2-amines, the regioisomers are formed in approximately equal amounts and, accordingly, the energy difference between these species is only 0.1 kcal/mol in terms of ?Gexp (?Gcalcd = 2.1 kcal/mol). The regioisomers were characterized by elemental analyses (C, H, N), HRESI+-MS and FTIR, 1D (1H, 13C) and 2D (1H,1H-COSY, 1H,1H-NOESY, 1H,13C-HSQC, 1H,13C-HMBC) NMR spectroscopies, and structures of six complexes (three KRs and three TRs) were elucidated by single-crystal X-ray diffraction.

AB - A class of tunable visible and near-infrared donor-acceptor Stenhouse adduct (DASA) photoswitches were efficiently synthesized in 2 to 4 steps from commercially available starting materials with minimal purification. Using either Meldrum's or barbituric acid "acceptors" in combination with aniline-based "donors" an absorption range spanning from 450 to 750 nm is obtained. Additionally, photoisomerization results in complete decoloration for all adducts, yielding fully transparent, colorless solutions and films. Detailed investigations using density functional theory, nuclear magnetic resonance, and visible absorption spectroscopies provide valuable insight into the unique structure-property relationships for this novel class of photoswitches. As a final demonstration, selective photochromism is accomplished in a variety of solvents and polymer matrices, a significant advantage for applications of this new generation of DASAs. PMID- 27700084 TI - Indium-Mediated Stereoselective Allylation. AB - Stereoselective indium-mediated organic reactions have enjoyed tremendous growth in the last 25 years. This is in part due to the insensitivity of allylindium to moisture, affording facile and practical reaction conditions coupled with outstanding functional group tolerance and minimal side reactions. Despite the plethora of articles about allylindium, there is much yet to be discovered and exploited for efficient and sustainable synthesis. In this Account, we describe indium-mediated synthetic methods for the preparation of chiral amines with the aim to present a balance of practical method development, novel asymmetric chemistry, and mechanistic understanding that impact multiple chemical and materials science disciplines. In 2005, we demonstrated the indium-mediated allylation of chiral hydrazones with complete diastereoselectivity (>99:1) and quantitative yields. Further, we revealed the first example of enantioselective indium-mediated allylation of hydrazones using catalytic (R)-3,3' bis(trifluoromethyl)-BINOL ligands to afford homoallylic amines with high enantioselectivity. The use of enantiopure perfluoroalkylsulfonate BINOLs greatly improved the indium-mediated allylation of N-acylhydrazones with exquisite enantiocontrol (99% yield, 99% ee). This laboratory has also investigated indium mediated asymmetric intramolecular cyclization in the presence of amino acid additives to deliver biologically relevant chromanes with excellent diastereoselectivity (dr >99:1). The effect of amino acid additives (N-Boc glycine) was further investigated during the indium-mediated allylation of isatins with allyl bromide to yield homoallylic alcohols in excellent yields in a short time with a wide range of functional group tolerance. Critical mechanistic insight was gained, and evidence suggests that the additive plays two roles: (1) to increase the rate of formation of allylindium from allyl bromide and In(0) and (2) to increase the nucleophilicity of the allylindium reagent, probably through disruption of aggregates and coordination to the metal. We recently reported the palladium-catalyzed umpolung allylation of hydrazones with allyl acetates in the presence of indium(I) iodide (InI) with excellent diastereoselectivity (up to 99:1). The conversion was found to be inversely proportional to the phosphine concentration, providing insight into the mechanism of the critical redox transmetalation process that has implications for other Pd-catalyzed umpolung type allylation processes. A detailed overview of the work in our lab is presented with the intention of stimulating further research interest in organoindium chemistry and its application in organic synthesis. PMID- 27700086 TI - Microwave Spectra, Structure, and Ring-Puckering Vibration of Octafluorocyclopentene. AB - The rotational spectra of octafluorocyclopentene (C5F8) has been measured for the first time using pulsed jet Fourier transform microwave spectroscopy in a frequency range of 6 to 16 GHz. As in the molecule cyclopentene, the carbon ring is nonplanar, and inversion through the plane results in an inversion pair of ground state vibrational energy levels with an inversion splitting of 18.4 MHz. This large amplitude motion leads to the vibration-rotation coupling of energy levels. The symmetric double minimum ring-puckering potential function was calculated, resulting in a barrier of 222 cm-1. The rotational constants A0 = 962.9590(1) MHz, B0 = 885.1643(4) MHz, C0 = 616.9523(4) MHz, A1 = 962.9590(1) MHz, B1 = 885.1643(4) MHz, C1 = 616.9528(4) MHz, and two centrifugal distortion constants for each state were determined for the parent species and all 13C isotopologues. A mixed coordinate molecular structure was determined from a least squares fit of the ground state rotational constants of the parent and each 13C isotopologue combined with the equilibrium bond lengths and angles from quantum chemical calculations. PMID- 27700085 TI - Effect of Conformers on Free Energies of Atmospheric Complexes. AB - In this article we show how to calculate free energies for atmospherically relevant complexes when multiple conformers and/or isomers are present. We explain why the thermal averaging methods used in several published works are incorrect. On the basis of our two sample cases, the sulfuric acid-pinic acid complex and the (H2SO4)3(NH3)3(H2O)4 cluster, we provide numerical evidence that the use of these incorrect formulas can result in errors larger than 1 kcal/mol. We recommend that if vibrational frequencies and thus Gibbs free energies of the individual conformers are unavailable, one should not attempt to correct for the presence of multiple conformers and instead use only the global minimum conformers for both reactants and products. On the contrary, if the free energies for the conformers are calculated for both reactants and products, their effect can be accounted for by the statistical mechanical methods presented in this article. PMID- 27700087 TI - How Does a Hydrophobic Macromolecule Respond to Mixed Osmolyte Environment? AB - The role of the protecting osmolyte Trimethyl N-oxide (TMAO) in counteracting the denaturing effect of urea on a protein is quite well established. However, the mechanistic role of osmolytes on the hydrophobic interaction underlying protein folding is a topic of contention and is emerging as a key area of biophysical interest. Although recent experiment and computer simulation have established that individual aqueous solution of TMAO and urea respectively stabilizes and destabilizes the collapsed conformation of a hydrophobic polymer, it remains to be explored how a mixed aqueous solution of protecting and denaturing osmolytes influences the conformations of the polymer. In order to bridge the gap, we have simulated the conformational behavior of both a model hydrophobic polymer and a synthetic polymer polystyrene in an aqueous mixture of TMAO and urea. Intriguingly, our free energy based simulations on both the systems show that even though a pure aqueous solution of TMAO stabilizes the collapsed or globular conformation of the hydrophobic polymer, addition of TMAO to an aqueous solution of urea further destabilizes the collapsed conformation of the hydrophobic polymer. We also observe that the extent of destabilization in a mixed osmolyte solution is relatively higher than that in pure aqueous urea solution. The reinforcement of the denaturation effect of the hydrophobic macromolecule in a mixed osmolyte solution is in stark contrast to the well-known counteracting role of TMAO in proteins under denaturing condition of urea. In both model and realistic systems, our results show that in a mixed aqueous solution, greater number of cosolutes preferentially bind to the extended conformation of the polymer relative to that in the collapsed conformation, thereby complying with Tanford-Wyman preferential solvation theory disfavoring the collapsed conformation. The results are robust across a range of osmolyte concentrations and multiple cosolute forcefields. Our findings unequivocally imply that the action of mixed osmolyte solution on hydrophobic polymer is significantly distinct from that of proteins. PMID- 27700088 TI - Classical and Quantum Shortcuts to Adiabaticity in a Tilted Piston. AB - Adiabatic quantum state evolution can be accelerated through a variety of shortcuts to adiabaticity. In one approach, a counterdiabatic quantum Hamiltonian, HCD, is constructed to suppress nonadiabatic excitations. In the analogous classical problem, a counterdiabatic classical Hamiltonian, HCD, ensures that the classical action remains constant even under rapid driving. Both the quantum and classical versions of this problem have been solved for the special case of scale-invariant driving, characterized by linear expansions, contractions, or translations of the system. Here we investigate an example of a non-scale-invariant system, a tilted piston. We solve exactly for the classical counterdiabatic Hamiltonian, HCD(q, p, t), which we then quantize to obtain a Hermitian operator, HCD(t). Using numerical simulations, we find that HCD effectively suppresses nonadiabatic excitations under rapid driving. These results offer a proof of principle, beyond the special case of scale-invariant driving, that quantum shortcuts to adiabaticity can successfully be constructed from their classical counterparts. PMID- 27700089 TI - New Melting Data of the Two Polymorphs of Prednisolone. AB - Prednisolone is known to exist in two anhydrous solid polymorphic forms. The substance is known to degrade upon melting, resulting in erroneous melting data, as shown by the widely scattered results reported in the literature. In this article, thermal analyses carried out at different scan rates show that the onset temperature and the enthalpy value of the signal increase with the scan rate and reach plateau values for high scan rates. Owing to flash scanning calorimetry, the plateau value for the temperature has been identified as the "true" temperature of melting of both polymorphs. This consistent set of new thermodynamic data on the two solid forms leads to the conclusion that both forms are unambiguously enantiotropes of each other. The solid-solid transition has been observed experimentally for the first time and has been confirmed by calculation. PMID- 27700090 TI - Benchmark Thermodynamic Properties of Methyl- and Methoxy-Benzamides: Comprehensive Experimental and Theoretical Study. AB - The enthalpies of formation of 2-, 3-, and 4-CH3-benzamide, as well as for 2-CH3O benzamide were measured by using combustion calorimetry. Vapor pressures of the isomeric CH3- and CH3O-benzamides were measured by using the transpiration method. The enthalpies of sublimation/vaporization of these compounds at 298 K were obtained from temperature dependencies of vapor pressures. The enthalpies of solution of the isomeric CH3- and CH3O-benzamides were measured with solution calorimetry. The enthalpies of sublimation of m- and p-substituted benzamides were independently derived with help of a solution calorimetry based procedure. The enthalpies of fusion of the CH3-benzamides were derived from DSC measurements. Thermochemical data on CH3- and CH3O-benzamides were collected, evaluated, and tested for internal consistency. A simple incremental procedure has been suggested for a quick appraisal of vaporization enthalpies of substituted benzamides. The high-level G4 quantum-chemical method was used for mutual validation of the experimental and theoretical gas phase enthalpies of formation. A remarkable ability of the G4 based atomization procedure to calculate reliable enthalpies of formation has been established for the set of aliphatic and aromatic amides. An outlook for the proper validation of the G4-AT procedure was discussed. PMID- 27700091 TI - Theoretical Study on Effects of Hydrogen-Bonding and Molecule-Cation Interactions on the Sensitivity of HMX. AB - To assess the effects of weak interactions on the sensitivity of HMX, eleven complexes of HMX (where six of them are hydrogen-bonding complexes, and the other five are molecular-cation complexes) have been studied via quantum chemical treatment. The geometric and electronic structures were determined using DFT B3LYP and MP2(full) methods with the 6-311++G(2df, 2p) and aug-cc-pVTZ basis sets. The changes of the bond dissociation energy (BDE) of the trigger bond (N NO2 in HMX) and nitro group charge have been computed on the detail consideration to access the sensitivity changes of HMX. The results indicate that upon complex forming, the BDE increases and the charge of nitro group turns more negative in complexes, suggesting that the strength of the N-NO2 trigger bond is enhanced then the sensitivity of HMX is reduced. Atom-in-molecules analysis have also been carried to understand the nature of intermolecular interactions and the strength of trigger bonds. PMID- 27700092 TI - An Automated Pipeline to Monitor System Performance in Liquid Chromatography Tandem Mass Spectrometry Proteomic Experiments. AB - We report the development of a completely automated pipeline to monitor system suitability in bottom-up proteomic experiments. LC-MS/MS runs are automatically imported into Skyline and multiple identification-free metrics are extracted from targeted peptides. These data are then uploaded to the Panorama Skyline document repository where metrics can be viewed in a web-based interface using powerful process control techniques, including Levey-Jennings and Pareto plots. The interface is versatile and takes user input, which allows the user significant control over the visualization of the data. The pipeline is vendor and instrument type neutral, supports multiple acquisition techniques (e.g., MS 1 filtering, data-independent acquisition, parallel reaction monitoring, and selected reaction monitoring), can track performance of multiple instruments, and requires no manual intervention aside from initial setup. Data can be viewed from any computer with Internet access and a web browser, facilitating sharing of QC data between researchers. Herein, we describe the use of this pipeline, termed Panorama AutoQC, to evaluate LC-MS/MS performance in a range of scenarios including identification of suboptimal instrument performance, evaluation of ultrahigh pressure chromatography, and identification of the major sources of variation throughout years of peptide data collection. PMID- 27700093 TI - Highly Efficient Free Energy Calculations of the Fe Equation of State Using Temperature-Dependent Effective Potential Method. AB - Free energy calculations at finite temperature based on ab initio molecular dynamics (AIMD) simulations have become possible, but they are still highly computationally demanding. Besides, achieving simultaneously high accuracy of the calculated results and efficiency of the computational algorithm is still a challenge. In this work we describe an efficient algorithm to determine accurate free energies of solids in simulations using the recently proposed temperature dependent effective potential method (TDEP). We provide a detailed analysis of numerical approximations employed in the TDEP algorithm. We show that for a model system considered in this work, hcp Fe, the obtained thermal equation of state at 2000 K is in excellent agreement with the results of standard calculations within the quasiharmonic approximation. PMID- 27700094 TI - The Molecular Origin of Ultrafast Water-Protein Coupled Interactions. AB - The fluctuations of hydration water and the protein are coupled together at the protein surface and often such water-protein dynamic interactions are controlled presumably by hydration water motions. However, direct evidence is scarce and it requires measuring the dynamics of hydration water and protein sidechain simultaneously. Here, we use a unique protein with a single tryptophan to directly probe interfacial water and related sidechain relaxations with temperature dependence. With systematic mutations to change local chemical identity and structural flexibility, we found that the sidechain relaxations are always slower than hydration water motions and the two dynamic processes are linearly correlated with the same energy barriers, indicating the same origin of both relaxations. The charge mutations change the rates of hydration water relaxations but not the relaxation barriers. These results convincingly show that the water-protein relaxations are strongly coupled and the hydration water molecules govern such fluctuations on the picosecond timescales. PMID- 27700095 TI - Halogen Bonding with Phosphine: Evidence for Mulliken Inner Complexes and the Importance of Relaxation Energy. AB - Intermolecular halogen bonding in complexes of phosphine and dihalogens has been theoretically investigated using explicitly correlated coupled cluster methods and symmetry adapted perturbation theory. The complexes H3P. . . ClF, H3P. . . BrF and H3P. . . IF are demonstrated to possess unusually strong interactions that are accompanied by an increase in the induction component of the interaction energy and significant elongation of the X-Y halogen distance on complex formation. The combination of these factors is indicative of Mulliken inner complexes and criteria for identifying this classification are further developed. The importance of choosing an electronic structure method that describes both dispersion and longer range interactions is demonstrated, along with the need to account for the change in geometry on complexation formation via relaxation energy and overall stabilisation energies. PMID- 27700096 TI - Homo- and Stereocomplex Crystallization of Star-Shaped Four-Armed Stereo Diblock Copolymers of Crystalline and Amorphous Poly(lactide)s: Effects of Incorporation and Position of Amorphous Blocks. AB - Star-shaped four-armed stereo diblock copolymers with an amorphous poly(DL lactide) (PDLLA) core and a crystalline poly(L-lactide) (PLLA) or poly(D-lactide) (PDLA) shell (4-DL-L and 4-DL-D) and with a crystalline PLLA or PDLA core and amorphous PDLLA shell (4-L-DL and 4-D-DL) copolymers were synthesized. The effects of incorporation and position of amorphous PDLLA blocks on homo- and stereocomplex (SC) crystallization behavior of unblended copolymers and their blends (4-DL-L/4-DL-D and 4-L-DL/4-D-DL) were investigated during isothermal crystallization from the melt and DSC heating. The incorporated amorphous PDLLA blocks disturbed the SC crystallization and orientation of SC lamellae in the copolymer blends as well as homo-crystallization and orientation of homo crystalline lamellae of the unblended copolymers compared to those reported for four-armed PLLA homopolymers or four-armed PLLA/four-armed PDLA homopolymer blends, irrespective of the position of amorphous PDLLA blocks. The disturbance effect was stronger for the amorphous PDLLA shell than for the amorphous PDLLA core. The crystallizability was higher for SC crystallites in the copolymer blends than for homo-crystallites in the unblended copolymers, irrespective of the position of amorphous PDLLA blocks. SC crystallization in the copolymer blends disclaimed the positional effects of crystalline PLLA and PDLA blocks and amorphous PDLLA blocks on spherulite growth rate and crystallinity.

AB - A complex mesoscopic organization is observed in systems containing ethylammonium nitrate (EAN) and two nonamphiphilic compounds, using wide and small angle X-ray scattering and molecular dynamics simulations. The macroscopically homogeneous mixtures exhibit a separation where an ionic liquid-rich region is percolating a molecular liquid-rich one, but no unmixing is observed. This effect was already reported in EAN-alcohol mixtures, but the models proposed so far cannot explain this behavior for a nonamphiphilic compound. PMID- 27700098 TI - Multi-Shape and Temperature Memory Effects via Strong Physical Confinement in Poly(Propylene Carbonate)/Graphene Oxide Nanocomposites. AB - The importance of filler-matrix interactions is generally recognized for mechanical property enhancement, their direct impact via physical confinement on diverse functional properties has remained poorly explored. We report here our effort in achieving versatile shape memory performances for a biodegradable poly(propylene carbonate) (PPC) matrix containing high contents of graphene oxide (GO). The excellent dispersion in the entire filler range (up to 20 wt%) allows precise morphological tuning, along with the physical filler-matrix interactions, contributing overall to a strong nano-confinement effect that positively affects the thermo-mechanical properties of nanocomposites. Only one glass transition temperature (Tg) of PPC is detected as GO content is below 10 wt%, corresponding to a slightly confined system, whereas two distinct Tgs are observed with GO content over 10 wt%, corresponding to a highly confined system. As such, tunable multi-shape memory effect can be achieved simply by tuning the filler contents. Dual shape memory effect (SME) is observed for slightly confined system, while a triple SME can be achieved via deformation at two distinct Tgs for highly confined system. More importantly, it is interesting to find that the switch temperature (Tsw) evolves linearly with the programing temperature (Tprog) for both slightly and highly confined system, with Tsw ~ Tprog for highly confined system, but Tsw < Tprog for slightly confined system. Our work suggests a highly flexible approach to take advantage of strong nano-confinement effect via tuning the content of GO within a single polymer to access versatile SME, such as dual, triple shape memory and temperature memory effect. PMID- 27700099 TI - Organic Acids Regulation of Chemical-Microbial Phosphorus Transformations in Soils. AB - We have used an integrated approach to study the mobility of inorganic phosphorus (P) from soil solid phase as well as the microbial biomass P and respiration at increasing doses of citric and oxalic acid in two different soils with contrasting agronomic P status. Citric or oxalic acids significantly increased soil solution P concentrations for doses over 2 mmol kg-1. However, low organic acid doses (<2 mmol kg-1) were associated with a steep increase in microbial biomass P, which was not seen for higher doses. In both soils, treatment with the tribasic citric acid led to a greater increase in soil solution P than the dibasic oxalic acid, likely due to the rapid degrading of oxalic acids in soils. After equilibration of soils with citric or oxalic acids, the adsorbed-to solution distribution coefficient (Kd) and desorption rate constants (k-1) decreased whereas an increase in the response time of solution P equilibration (Tc) was observed. The extent of this effect was shown to be both soil and organic acid specific. Our results illustrate the critical thresholds of organic acid concentration necessary to mobilize sorbed and precipitated P, bringing new insight on how the exudation of organic acids regulate chemical-microbial soil phosphorus transformations. PMID- 27700101 TI - Layer-by-Layer Sorting of Rhenium Disulfide via High-Density Isopycnic Density Gradient Ultracentrifugation. AB - Isopycnic density gradient ultracentrifugation (iDGU) has been widely applied to sort nanomaterials by their physical and electronic structure. However, the commonly used density-gradient medium iodixanol has a finite maximum buoyant density that prevents the use of iDGU for high-density nanomaterials. Here, we overcome this limit by adding cesium chloride (CsCl) to iodixanol, thus increasing its maximum buoyant density to the point where the high-density two dimensional nanomaterial rhenium disulfide (ReS2) can be sorted in a layer-by layer manner with iDGU. The resulting aqueous ReS2 dispersions show photoluminescence at ~1.5 eV, which is consistent with its direct bandgap semiconductor electronic structure. Furthermore, photocurrent measurements on thin films formed from solution-processed ReS2 show a spectral response that is consistent with optical absorbance and photoluminescence data. In addition to providing a pathway for effective solution processing of ReS2, this work establishes a general methodology for sorting high-density nanomaterials via iDGU. PMID- 27700102 TI - Modulation of Low-Frequency Acoustic Vibrations in Semiconductor Nanocrystals through Choice of Surface Ligand. AB - Recent experimental and theoretical results have highlighted the surprisingly dominant role of acoustic phonons in regulating dynamic processes in nanocrystals. While it has been known for many years that acoustic phonon frequencies in nanocrystals depend on their size, strategies for tuning acoustic phonon energy at a given fixed size were not available. Here, we show that acoustic phonon frequencies in colloidal quantum dots (QDs) can be tuned through choice of the surface ligand. Using low-frequency Raman spectroscopy, we explore the dependence of the l = 0 acoustic phonon resonance in CdSe QDs on ligand size, molecular weight, and chemical functionality. Based on these aggregated observations, we conclude that the primary mechanism for this effect is mass loading of the QD surface, and that interactions between ligands and with the surrounding environment play a comparatively minor yet non-negligible role. PMID- 27700100 TI - Proteolysis by Granzyme B Enhances Presentation of Autoantigenic Peptidylarginine Deiminase 4 Epitopes in Rheumatoid Arthritis. AB - Proteolysis of autoantigens can alter normal MHC class II antigen processing and has been implicated in the induction of autoimmune diseases. Many autoantigens are substrates for the protease granzyme B (GrB), but the mechanistic significance of this association is unknown. Peptidylarginine deiminase 4 (PAD4) is a frequent target of autoantibodies in patients with rheumatoid arthritis (RA) and a substrate for GrB. RA is strongly associated with specific MHC class II alleles, and elevated levels of GrB and PAD4 are found in the joints of RA patients, suggesting that GrB may alter the presentation of PAD4 by RA-associated class II alleles. In this study, complementary proteomic and immunologic approaches were utilized to define the effects of GrB cleavage on the structure, processing, and immunogenicity of PAD4. Hydrogen-deuterium exchange and a cell free MHC class II antigen processing system revealed that proteolysis of PAD4 by GrB induced discrete structural changes in PAD4 that promoted enhanced presentation of several immunogenic peptides capable of stimulating PAD4-specific CD4+ T cells from patients with RA. This work demonstrates the existence of PAD4 specific T cells in patients with RA and supports a mechanistic role for GrB in enhancing the presentation of autoantigenic CD4+ T cell epitopes. PMID- 27700103 TI - Identification of a Novel Autoimmune Peptide Epitope of Prostein in Prostate Cancer. AB - There is a demand for novel targets and approaches to diagnose and treat prostate cancer (PCA). In this context, serum and plasma samples from a total of 609 individuals from two independent patient cohorts were screened for IgG reactivity against a sum of 3833 human protein fragments. Starting from planar protein arrays with 3786 protein fragments to screen 80 patients with and without PCA diagnosis, 161 fragments (4%) were chosen for further analysis based on their reactivity profiles. Adding 71 antigens from literature, the selection of antigens was corroborated for their reactivity in a set of 550 samples using suspension bead arrays. The antigens prostein (SLC45A3), TATA-box binding protein (TBP), and insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2) showed higher reactivity in PCA patients with late disease compared with early disease. Because of its prostate tissue specificity, we focused on prostein and continued with mapping epitopes of the 66-mer protein fragment using patient samples. Using bead-based assays and 15-mer peptides, a minimal peptide epitope was identified and refined by alanine scanning to the KPxAPFP. Further sequence alignment of this motif revealed homology to transmembrane protein 79 (TMEM79) and TGF-beta induced factor 2 (TGIF2), thus providing a reasoning for cross-reactivity found in females. A comprehensive workflow to discover and validate IgG reactivity against prostein and homologous targets in human serum and plasma was applied. This study provides useful information when searching for novel biomarkers or drug targets that are guided by the reactivity of the immune system against autoantigens. PMID- 27700106 TI - Micropatterning of Phase-Segregated Supported Lipid Bilayers and Binary Lipid Phases through Polymer Stencil Lift-Off. AB - Supported lipid bilayers (SLBs) provide an excellent model system for studying structural and functional characteristics of biomembranes. Patterning model membranes on solid supports has elicited much interest because lipid bilayer arrays at cellular or sub-cellular scales provide attractive platforms for reconstituting tissue-like conditions for cell culture, and for creating simplified physiological environments to study biological processes. Phase segregated SLB patterns can be especially useful for such studies, as the selective functionalization of the lipid phases with different lipids, receptors or proteins can be achieved to mimic the key features of plasma membrane. However, it remains challenging to pattern phase-segregated lipid bilayers and to spatially control the lipid phases at the micron scale. Current methods to achieve this involve multiple surface modification and patterning steps, elaborate techniques such as microfluidic, microcontact printing, or electrochemical control, among others. To overcome the complexity in producing phase-segregated patterns, we have developed simple and rapid strategies to pattern SLBs with phase separation utilizing the polymer stencil lift-off (PSLO) technique. PSLO is a powerful technique for SLB patterning, since it allows the faithful pattern transfer of micron-sized lipid domains onto solid surfaces under aqueous conditions, which eliminates the need for controlled humidity and reduces the risk of bilayer disruption through drying. By integrating post-etching substrate cleaning and a blocking treatment, well-defined homogeneous and phase segregated SLB patterns were achieved with lipid mobility that matches that of SLBs formed on clean SiO2 wafer substrates. A two-step incubation method was also developed for patterning binary lipid phases, which allowed precise control of their position and geometries. The created phase-segregated SLB patterns were used to study lipid phase behavior within confined areas, and quantitative analysis showed that smaller pattern sizes resulted in smaller gel phase domains, which also covered a smaller fraction of the total patterned SLB area. This was attributed to the decreased mobility of the bottom leaflet of the SLB which lies in close proximity to the substrate, and the resulting hindered exchange of lipid molecules between the bottom and upper leaflets through the SLB boundary. By further integration with functional groups, the phase-segregated lipid bilayer patterns might find relevant application in tissue engineering, biophysical studies of biomolecular and cellular interactions, and biosensing platforms. PMID- 27700104 TI - Structural Attributes and Photodynamics of Visible Spectrum Quantum Emitters in Hexagonal Boron Nitride. AB - Newly discovered van der Waals materials like MoS2, WSe2, hexagonal boron nitride (h-BN), and recently C2N have sparked intensive research to unveil the quantum behavior associated with their 2D structure. Of great interest are 2D materials that host single quantum emitters. h-BN, with a band gap of 5.95 eV, has been shown to host single quantum emitters which are stable at room temperature in the UV and visible spectral range. In this paper we investigate correlations between h-BN structural features and emitter location from bulk down to the monolayer at room temperature. We demonstrate that chemical etching and ion irradiation can generate emitters in h-BN. We analyze the emitters' spectral features and show that they are dominated by the interaction of their electronic transition with a single Raman active mode of h-BN. Photodynamics analysis reveals diverse rates between the electronic states of the emitter. The emitters show excellent photo stability even under ambient conditions and in monolayers. Comparing the excitation polarization between different emitters unveils a connection between defect orientation and the h-BN hexagonal structure. The sharp spectral features, color diversity, room-temperature stability, long-lived metastable states, ease of fabrication, proximity of the emitters to the environment, outstanding chemical stability, and biocompatibility of h-BN provide a completely new class of systems that can be used for sensing and quantum photonics applications.

AB - Ricinoleic acid as the characteristic fatty acid of Secale cornutum oil is a good marker for Secale cornutum impurities in cereal. The presented screening for ricinoleic acid in rye by high-performance thin-layer chromatography with fluorescence detection (HPTLC-FLD) offers a selective and sensitive method for the determination of Secale cornutum and is very different from existing gas chromatographic analyses. Lipid extraction was followed by transesterification and solid-phase extraction cleanup; thereafter, extracts were selectively derivatized with 2-naphthoyl chloride and analyzed by HPTLC-FLD with silica gel plates and cyclohexane/diisopropyl ether/formic acid (86:14:1, v/v/v) as mobile phase. For quantitation, the enhanced fluorescence was scanned at 280/>340 nm. Limits of detection and quantitation of 0.1 and 0.4 mg ricinoleic acid/kg of rye were obtained, which enables the determination of Secale cornutum far below the maximum admitted level. With near-100% recoveries and low standard deviations at relevant spiking levels, reliable results were guaranteed.

AB - The total synthesis of rutaecarpine (1) and luotonin A (2) is described through controlled cyclization of a common aldimine intermediate 5 derived from ethyl-2 aminocinnamate and quinazolinone-2-carbaldehyde. The cyanide-mediated imino Stetter reaction of aldimine 5 provided the corresponding indole derivative 3, from which the total synthesis of rutaecarpine (1) was completed via the formation of a 6-membered C-ring. On the other hand, microwave-assisted thermal 6pi-electrocyclization of the common intermediate 5, followed by the formation of a 5-membered C'-ring, allowed the completion of the total synthesis of luotonin A (2). PMID- 27700108 TI - Toward Single Electron Nanoelectronics Using Self-Assembled DNA Structure. AB - DNA based structures offer an adaptable and robust way to develop customized nanostructures for various purposes in bionanotechnology. One main aim in this field is to develop a DNA nanobreadboard for a controllable attachment of nanoparticles or biomolecules to form specific nanoelectronic devices. Here we conjugate three gold nanoparticles on a defined size TX-tile assembly into a linear pattern to form nanometer scale isolated islands that could be utilized in a room temperature single electron transistor. To demonstrate this, conjugated structures were trapped using dielectrophoresis for current-voltage characterization. After trapping only high resistance behavior was observed. However, after extending the islands by chemical growth of gold, several structures exhibited Coulomb blockade behavior from 4.2 K up to room temperature, which gives a good indication that self-assembled DNA structures could be used for nanoelectronic patterning and single electron devices. PMID- 27700109 TI - Investigating the Correlation between Miscibility and Physical Stability of Amorphous Solid Dispersions Using Fluorescence-Based Techniques. AB - The purpose of this study was to investigate the feasibility of using a fluorescence-based technique to evaluate drug-polymer miscibility and to probe the correlation between miscibility and physical stability of amorphous solid dispersions (ASDs). Indomethacin-hydroxypropyl methylcellulose (IDM-HPMC), indomethacin-hydroxypropyl methylcellulose acetate succinate, and indomethacin polyvinylpyrrolidone (IDM-PVP) were used as model systems. The miscibility of the IDM-polymer systems was evaluated by fluorescence spectroscopy, fluorescence imaging, differential scanning calorimetry (DSC), and infrared (IR) spectroscopy. The physical stability of IDM-polymer ASDs stored at 40 degrees C was evaluated using fluorescence imaging and X-ray diffraction (XRD). The experimentally determined miscibility limit of IDM with the polymers was 50-60%, 20-30%, and 70 80% drug loading for HPMC, HPMCAS, and PVP, respectively. The X-ray results showed that for IDM-HPMC ASDs, samples with a drug loading of less than 50% were maintained in amorphous form during the study period, while samples with drug loadings higher than 50% crystallized within 15 days. For IDM-HPMCAS ASDs, samples with drug loading less than 30% remained amorphous, while samples with drug loadings higher than 30% crystallized within 10 days. IDM-PVP ASDs were found to be resistant to crystallization for all compositions. Thus, a good correlation was observed between phase separation and reduced physical stability, suggesting that miscibility is indeed an important ASDs characteristic. In addition, fluorescence-based techniques show promise in the evaluation of drug polymer miscibility. PMID- 27700110 TI - Single Gold Nanorod Charge Modulation in an Ion Gel Device. AB - A reliable and reproducible method to rapidly charge single gold nanocrystals in a solid-state device is reported. Gold nanorods (Au NRs) were integrated into an ion gel capacitor, enabling them to be charged in a transparent and highly capacitive device, ideal for optical transmission. Changes in the electron concentration of a single Au NR were observed with dark-field imaging spectroscopy via localized surface plasmon resonance (LSPR) shifts in the scattering spectrum. A time-resolved, laser-illuminated, dark-field system was developed to enable direct measurement of single particle charging rates with time resolution below one millisecond. The added sensitivity of this new approach has enabled the optical detection of fewer than 110 electrons on a single Au NR. Single wavelength resonance shifts provide a much faster, more sensitive method for all surface plasmon-based sensing applications. PMID- 27700111 TI - Transpapillary (Nipple) Delivery of Macromolecules to the Breast: Proof of Concept Study. AB - Localized drug delivery to the breast can maximize drug concentration at the target site and minimize systemic drug distribution. To this end, the study explored the feasibility of delivering macromolecules to the breast through mammary papilla (nipple). The in vitro penetration of model macromolecules (inulin, dextran, ovalbumin, and bovine serum albumin) varying in molecular weight from 5 to 67 kDa was studied using excised porcine and human mammary papilla. The penetration of macromolecules decreased with increase in molecular weight. The penetration of the macromolecules was significantly higher through the mammary papilla in comparison to breast skin. In vitro penetration of the macromolecules was similar in human and porcine mammary papilla. Iontophoresis was used to enhance the transport of bovine serum albumin (BSA) through the mammary papilla. The flux and cumulative amount permeated was increased by 2- to 4-fold by iontophoresis. The macromolecules were transported through the ducts and the surrounding connective tissue in the mammary papilla. Overall, the results from this study for the first time demonstrate the feasibility of delivering macromolecules through the mammary papilla. These findings have implications for developing safe and effective localized therapeutic approaches for breast cancer. PMID- 27700112 TI - Physicochemical and Preclinical Evaluation of Spermine-Derived Surfactant Liposomes for in Vitro and in Vivo siRNA-Delivery to Liver Macrophages. AB - Herein we report on a liposomal system for siRNA delivery consisting of cholesterol (Chol), distearoylphosphatidylcholine (DSPC), and surfactant TF (1 hydroxy-50-amino-3,4,7,10,13,16,19,22-octaoxa-37,41,45-triaza-pentacontane), a novel spermine derivative (HO-EG8-C12-spermine) which has shown improved siRNA delivery to cells in vitro and in vivo. Predominantly single-walled liposomes with reproducible sizes and moderately broad size distributions were generated with an automated extrusion device. The liposomes remained stable when prepared in the presence of siRNA at N/P ratios of 17-34. However, when mixed with human serum in equal volumes, larger aggregates in the size range of several hundred nanometers were observed by dynamic light scattering. These larger aggregates could potentially limit prolonged in vivo applications. Aggregate formation could be reduced by the addition of a cholesterol-hyperbranched polyglycerol surfactant (hbPG) that sterically shields the liposomal surface against serum induced aggregation. In vitro experiments with murine macrophages utilizing macrophage specific anti-CD68 siRNA loaded liposomes showed potent and sequence specific reduction of CD68 transcript levels without cytotoxicity. Experiments in mice using intravenous application of CW800 NHS ester labeled liposomes, near-infrared in vivo imaging, and fluorescent assisted cell sorting of inflammatory cells demonstrated an almost quantitative accumulation of these liposomes, with and without hbPG, in the liver and a specific knockdown of CD68 mRNA of up to 70% in liver resident macrophages. It was found that aggregate formation of TF liposomes in serum does not significantly affect in vivo siRNA delivery to these central inflammatory cells of the liver. PMID- 27700114 TI - Microcapsule Buckling Triggered by Compression-Induced Interfacial Phase Change. AB - There is an emerging trend towards the fabrication of microcapsules at liquid interfaces. In order to control the parameters of such capsules, the interfacial processes governing their formation must be understood. Here, poly(vinyl alcohol) films are assembled at the interface of water-in-oil microfluidic droplets. The polymer is cross-linked using cucurbit[8]uril ternary supramolecular complexes. It is shown that compression-induced phase change causes the onset of buckling in the interfacial film. On evaporative compression, the interfacial film both increases in density and thickens, until it reaches a critical density and a phase change occurs. We show that this increase in density can be simply related to the film Poisson ratio and area compression. This description captures fundamentals of many compressive interfacial phase changes and can also explain the observation of a fixed thickness-to-radius ratio at buckling, (T/R)buck. PMID- 27700113 TI - Resonance Coupling in Silicon Nanosphere-J-Aggregate Heterostructures. AB - Due to their optical magnetic and electric resonances associated with the high refractive index, dielectric silicon nanoparticles have been explored as novel nanocavities that are excellent candidates for enhancing various light-matter interactions at the nanoscale. Here, from both of theoretical and experimental aspects, we explored resonance coupling between excitons and magnetic/electric resonances in heterostructures composed of the silicon nanoparticle coated with a molecular J-aggregate shell. The resonance coupling was originated from coherent energy transfer between the exciton and magnetic/electric modes, which was manifested by quenching dips on the scattering spectrum due to formation of hybrid modes. The influences of various parameters, including the molecular oscillation strength, molecular absorption line width, molecular shell thickness, refractive index of the surrounding environment, and separation between the core and shell, on the resonance coupling behaviors were scrutinized. In particular, the resonance coupling can approach the strong coupling regime by choosing appropriate molecular parameters, where an anticrossing behavior with a mode splitting of 100 meV was observed on the energy diagram. Most interestingly, the hybrid modes in such dielectric heterostructure can exhibit unidirectional light scattering behaviors, which cannot be achieved by those in plexcitonic nanoparticle composed of a metal nanoparticle core and a molecular shell. PMID- 27700115 TI - Rotation-Facilitated Rapid Transport of Nanorods in Mucosal Tissues. AB - Mucus is a viscoelastic gel layer that typically protects exposed surfaces of the gastrointestinal (GI) tract, lung airways, and other mucosal tissues. Particles targeted to these tissues can be efficiently trapped and removed by mucus, thereby limiting the effectiveness of such drug delivery systems. In this study, we experimentally and theoretically demonstrated that cylindrical nanoparticles (NPs), such as mesoporous silica nanorods and calcium phosphate nanorods, have superior transport and trafficking capability in mucus compared with spheres of the same chemistry. The higher diffusivity of nanorods leads to deeper mucus penetration and a longer retention time in the GI tract than that of their spherical counterparts. Molecular simulations and stimulated emission of depletion (STED) microscopy revealed that this anomalous phenomenon can be attributed to the rotational dynamics of the NPs facilitated by the mucin fibers and the shear flow. These findings shed new light on the shape design of NP-based drug delivery systems targeted to mucosal and tumor sites that possess a fibrous structure/porous medium. PMID- 27700116 TI - Insights into drying of non-circular sessile nanofluid droplet towards multi scale surface patterning using a wall-less confinement architecture. AB - Surface patterning with functional colloids is an important research area due to its widespread applicability in domains ranging from nano-electronics, pharmaceutics, semi-conductors, photovoltaics among others. To this endeavour, we propose a low-cost patterning technique that aspires to eliminate the more expensive methodologies presently in practise. Using a simple document stamp on which patterns of any geometry can be embossed, we are able to print two dimensional mm-scale "wall-less confinement" using ink based hydrophobic fence on any plasma treated superhydrophilic surface. The confinement is subsequently filled with nanocolloidal liquid(s). Using the confinement geometry, we are able to control the 3D shape of the droplet to exhibit multiple interfacial curvatures. The droplet in the "wall-less confinements" evaporates naturally exhibiting unique geometry (curvature) induced flow structures which induce the nanoparticles to self-assemble into functional patterns. We have also shown that by modifying the geometry of the pattern, evaporation, flow and particle deposition dynamics get altered leading to precipitate topologies from macro to microscales. We, present two such geometrical designs which demonstrate the capability of modifying both the macroscopic as well as the microscopic features of the final precipitate. We have also provided a description of the physical mechanisms of the drying process by resolving the unique flow pattern using a combination of imaging and MUPIV (micro particle image velocimetry). These provide insights into the coupled dynamics of evaporation and flow responsible for the evolution of particle deposition pattern. Precipitate characterization using SEM and dark-field microscopy highlight the transformation in the deposit morphology.

AB - An efficient domino reaction combining different classes of pericyclic reactions leads to chiral complex polycyclic indoline-based architectures from achiral starting materials under mild conditions. This practical method is based on the ability of iron(III) chloride to promote both 4pi electrocyclizations of 2,4 dienals and the C2-C3 umpolung of N-acetylindoles during the dearomative (3 + 2) cycloadditions. PMID- 27700118 TI - Origin of pKa Shifts of Internal Lysine Residues in SNase Studied Via Equal-Molar VMMS Simulations in Explicit Water. AB - Protein internal ionizable groups can exhibit large shifts in pKa values. Although the environment and interaction changes have been extensively studied both experimentally and computationally, direct calculation of pKa values of these internal ionizable groups in explicit water is challenging due to energy barriers in solvent interaction and in conformational transition. The virtual mixture of multiple states (VMMS) method is a new approach designed to study chemical state equilibrium. This method constructs a virtual mixture of multiple chemical states in order to sample the conformational space of all states simultaneously and to avoid crossing energy barriers related to state transition. By applying VMMS to 25 variants of staphylococcal nuclease with lysine residues at internal positions, we obtained the pKa values of these lysine residues and investigated the physics underlining the pKa shifts. Our calculation results agree reasonably well with experimental measurements, validating the VMMS method for pKa calculation and providing molecular details of the protonation equilibrium for protein internal ionizable groups. Based on our analyses of protein conformation relaxation, lysine side chain flexibility, water penetration, and the microenvironment, we conclude that the hydrophobicity of the microenvironment around the lysine side chain (which affects water penetration differently for different protonation states) plays an important role in the pKa shifts.

AB - An unusual benzannulation reaction has been realized by integrating intermolecular adol condensation with subsequent intramolercular base-promoted homolytic aromatic substitution. This novel cascade reaction provides a straightforward approach toward various naphtho-fused oxindoles from 2 halobenzaldehydes and indolin-2-ones in the presence of Cs2CO3 in DMSO. The enolates of indolin-2-ones as new and internal electron donors have been demonstrated to initiate intramolecular radical dehalogenative coupling.

In the presence of a new squaramide-based quaternized cinchona alkaloid-derived catalyst and aqueous base, benzyl, allyl, and propargyl halides react with racemic substituted oxindoles to generate densely functionalized products with the two contiguous stereocenters, one of which is an all-carbon quaternary. PMID- 27700119 TI - Biomimetic ApoE-Reconstituted High Density Lipoprotein Nanocarrier for Blood Brain Barrier Penetration and Amyloid Beta-Targeting Drug Delivery. AB - Amyloid beta (Abeta) and its aggregation forms in the brain have been suggested as key targets for the therapy of Alzheimer's disease (AD). Therefore, the development of nanocarriers that possess both blood-brain barrier permeability and Abeta-targeting ability is of great importance for the intervention of AD. Here we constructed a biomimetic nanocarrier named apolipoprotein E (ApoE) reconstituted high density lipoprotein nanocarrier (ANC) from recombinant ApoE and synthetic lipids to achieve the above goals. alpha-Mangostin (alpha-M), a polyphenolic agent that can inhibit the formation of Abeta oligomers and fibrils and accelerate Abeta cellular degradation, was used as the model drug. Compared with the control liposome, ANC demonstrated about 54-fold higher cellular uptake in brain endothelial cell line in vitro in an ApoE-dependent manner and much higher brain delivery efficiency in vivo. Confocal microscopy analysis witnessed the penetration of ANC across the brain vessels and its accumulation at the surrounding of Abeta aggregates. Following the loading of alpha-M, the Abeta binding affinity of the nanoformulation (ANC-alpha-M) was not reduced but even enhanced. The effect of ANC-alpha-M on facilitating the microglia-mediated uptake and degradation of Abeta1-42 was enhanced by 336% and 29-fold when compared with that of the nontreated control and also much higher than that of ANC. Following intravenous administration for 2 to 4 weeks, ANC-alpha-M exhibited the most efficient efficacy in decreasing amyloid deposition, attenuating microgliosis, and rescuing memory defect in SAMP8 mice, an AD mouse model. Taken together, the findings of this work provided strong evidence that the ApoE-based biomimetic nanocarrier could provide a promising platform for brain drug delivery toward the treatment of AD.

Simple, commercially available CoBr2 was used as a cobalt source. The developed alkynylation strategy is robust and efficient and has a broad substrate scope including 1 degrees , 2 degrees , and 3 degrees benzylamines. The mechanistic study shows that C-H bond cleavage is reversible, and the kinetic study illustrates that the rate of reaction depends solely on the catalyst. PMID- 27700125 TI - Anticorrelation of Photoluminescence from Gold Nanoparticle Dimers with Hot-Spot Intensity. AB - Bulk gold shows photoluminescence (PL) with a negligible quantum yield of ~10-10, which can be increased by orders of magnitude in the case of gold nanoparticles. This bears huge potential to use noble metal nanoparticles as fluorescent and unbleachable stains in bioimaging or for optical data storage. Commonly, the enhancement of the PL yield is attributed to nanoparticle plasmons, specifically to the enhancements of scattering or absorption cross sections. Tuning the shape or geometry of gold nanostructures (e.g., via reducing the distance between two nanoparticles) allows for redshifting both the scattering and the PL spectra. However, while the scattering cross section increases with a plasmonic redshift, the PL yield decreases, indicating that the common simple picture of a plasmonically boosted gold luminescence needs more detailed consideration. In particular, precise experiments as well as numerical simulations are required. Hence, we systematically varied the distance between the tips of two gold bipyramids on the nanometer scale using AFM manipulation and recorded the PL and the scattering spectra for each separation. We find that the PL intensity decreases as the interparticle coupling increases. This anticorrelation is explained by a theoretical model where both the gold-intrinsic d-band hole recombination probabilities as well as the field strength inside the nanostructure are considered. The scattering cross section or the field strength in the hot-spot between the tips of the bipyramids are not relevant for the PL intensity. Besides, we not only observe PL supported by dipolar plasmon resonances, but also measure and simulate PL supported by higher order plasmonic modes. PMID- 27700124 TI - Tenofovir Containing Thiolated Chitosan Core/Shell Nanofibers: In Vitro and in Vivo Evaluations. AB - It is hypothesized that thiolated chitosan (TCS) core/shell nanofibers (NFs) can enhance the drug loading of tenofovir, a model low molecular weight and highly water-soluble drug molecule, and improve its mucoadhesivity and in vivo safety. To test this hypothesis, poly(ethylene oxide) (PEO) core with TCS and polylactic acid (PLA) shell NFs are fabricated by a coaxial electrospinning technique. The morphology, drug loading, drug release profiles, cytotoxicity and mucoadhesion of the NFs are analyzed using scanning and transmission electron microscopies, liquid chromatography, cytotoxicity assays on VK2/E6E7 and End1/E6E7 cell lines and Lactobacilli crispatus, fluorescence imaging and periodic acid colorimetric method, respectively. In vivo safety studies are performed in C57BL/6 mice followed by H&E and immunohistochemical (CD45) staining analysis of genital tract. The mean diameters of PEO, PEO/TCS, and PEO/TCS-PLA NFs are 118.56, 9.95, and 99.53 nm, respectively. The NFs exhibit smooth surface. The drug loading (13% 25%, w/w) increased by 10-fold compared to a nanoparticle formulation due to the application of the electrospinning technique. The NFs are noncytotoxic at the concentration of 1 mg/mL. The PEO/TCS-PLA core/shell NFs mostly exhibit a release kinetic following Weibull model (r2 = 0.9914), indicating the drug release from a matrix system. The core/shell NFs are 40-60-fold more bioadhesive than the pure PEO based NFs. The NFs are nontoxic and noninflammatory in vivo after daily treatment for up to 7 days. Owing to their enhanced drug loading and preliminary safety profile, the TCS core/shell NFs are promising candidates for the topical delivery of HIV/AIDS microbicides such as tenofovir. PMID- 27700126 TI - Three-Year Clinical Evaluation of Class I Restorations in Posterior Teeth. Effects of Two Adhesive Systems. AB - This longitudinal study evaluated the clinical performance of 97 direct class I resin composite restorations after 3 years. The restorations were performed using 2 types of adhesive systems: (1) AdperTM Single Bond Plus (SB) (3M ESPE, 3mespe.com), which is a two-step etch-and-rinse system, and (2) Adper ScotchbondTM SE (SE) (3M ESPE), which is a two-step self-etching system. Two calibrated examiners evaluated the restorations using modified US Public Health Service criteria. The materials were applied following the manufacturer's instructions, and 15 patients received at least one of the two adhesive systems. The restorations were evaluated 7 days after placement (baseline) and again after 3 years. Statistical analysis was performed using a proportion t-test at a significance level of 5% (P < .05). At baseline, all restorations received an Alpha score for the variable marginal discoloration and marginal integrity. After 3 years, marginal discoloration received an Alpha score for 53.19% of the restorations performed with SB and 52.08% with SE. Marginal integrity was rated as Alpha for 65.96% and 68.75% of the restorations with SB and SE systems, respectively. The remaining restorations received Bravo scores for all variables. Eight restored teeth presented postoperative sensitivity at baseline (5 SB; 3 SE), but no sensitivity was found after 3 years. No secondary caries was verified. No statistically significant differences were observed between the teeth restored with the SB and SE systems for marginal discoloration (P = .7880) and marginal integrity (P = .8132) after 3 years. Direct class I resin composite restorations performed with a two-step etch-and-rinse and a two-step self-etching adhesive system demonstrated satisfactory clinical performance after 3 years.

PMID- 27700128 TI - How to Bond Zirconia: The APC Concept. AB - Zirconia has become one of the most popular materials in dentistry. New high translucent zirconia ceramics have favorable optical properties and can be applied as monolithic full-contour restorations in various clinical indications for posterior and anterior teeth. However, having reliable cementation protocols is fundamental for clinical success of indirect ceramic dental restorations, including those made from zirconia materials. Resin bonding supports ceramic restorations and is necessary for onlays, laminate veneers, and resinbonded fixed dental prostheses. The APC zirconia-bonding concept is based on decades of research on how to achieve high and long-term durable bond strengths to high strength ceramics. It includes three practical steps: (A) airparticle abrasion, (P) zirconia primer, and (C) adhesive composite resin. This article discusses the history and development of high-translucent zirconia and explains the necessity for proper cementation. The rationale and science behind a simplified zirconia bonding concept is explained and illustrated with a clinical case presentation. PMID- 27700129 TI - Is Your Dental Adhesive Forgiving?

Dental adhesives that are considered forgiving are less technique sensitive, thus potentially yielding more reliable bonding under various clinical conditions.

PMID- 27700135 TI - Neonatal Androgen Exposure Causes Persistent Gut Microbiota Dysbiosis Related to Metabolic Disease in Adult Female Rats. AB - Alterations of gut microbiome have been proposed to play a role in metabolic disease, but the major determinants of microbiota composition remain ill defined. Nutritional and sex hormone challenges, especially during early development, have been shown to permanently alter adult female phenotype and contribute to metabolic disturbances. In this study, we implemented large-scale microbiome analyses to fecal samples from groups of female rats sequentially subjected to various obesogenic manipulations, including sex hormone perturbations by means of neonatal androgenization or adult ovariectomy (OVX), as a model of menopause, to establish whether these phenomena are related to changes in gut microbiota. Basic metabolic profiles concerning glucose/insulin homeostasis were also explored. The effects of the sex hormonal perturbations, either developmentally (androgenization) or in adulthood (OVX), clearly outshone the impact of nutritional interventions, especially concerning the gut microbiota profile. Notably, we observed a lower diversity in the androgenized group, with the highest Firmicutes to Bacteroidetes ratio, supporting the occurrence of durable alterations in gut microbiota composition, even in adulthood. Moreover, the elimination of adult ovarian secretions by OVX affected the richness of gut microbiota. Our data are the first to document the durable impact of sex steroid manipulations, and particularly early androgenization, on gut microbiota composition. Such dysbiosis is likely to contribute to the metabolic perturbations of conditions of obesity linked to gonadal dysfunction in the female. PMID- 27700136 TI - Adiponectin Deficiency Leads to Female Subfertility and Ovarian Dysfunctions in Mice. AB - Adipose tissue plays an important role in regulating female fertility, owing to not only its energy stores but also the endocrine actions of secreted adipokines. As one of the adipokines, adiponectin is almost exclusively secreted from the fat, and its circulating concentration is paradoxically reduced in obesity. Although recent studies implied a purported positive role of adiponectin in ovarian functions, definitive in vivo evidence has been sorely lacking. We have consistently observed subfertility in female adiponectin null mice and therefore postulated a protective role of adiponectin in ovarian functions. Female adiponectin null mice displayed impaired fertility, reduced retrieval of oocytes, disrupted estrous cycle, elevated number of atretic follicles, and impaired late folliculogenesis. Analysis of their sera revealed a significant decrease in estradiol and FSH but an increase in LH and testosterone at proestrus. In addition, we found marked reduction of progesterone levels at diestrus, a significant decrease in LH receptor expression as well as in the number of GnRH immunoreactive neurons. Adiponectin deficiency also altered the peak concentrations of LH surge and led to lower expression of Cytochrome P450 family 11 subfamily A member 1 (P450scc), an enzyme critical for progesterone synthesis, as well as an increase in BCL2 associated X, apoptosis regulator and Insulin like growth factor binding protein 4 in atretic follicles. These physiological and molecular events were independent of insulin sensitivity. Thus, we have revealed a novel mechanism linking adiponectin and female fertility that entails regulation of reproductive hormone balance and ovarian follicle development.

AB - Lifeless planets with CO2 atmospheres produce CO by CO2 photolysis. On planets around M dwarfs, CO is a long-lived atmospheric compound, as long as UV emission due to the star's chromospheric activity lasts, and the sink of CO and O2 in seawater is small compared to its atmospheric production. Atmospheres containing reduced compounds, like CO, may undergo further energetic and chemical processing to give rise to organic compounds of potential importance for the origin of life. We calculated the yield of organic compounds from CO2-rich atmospheres of planets orbiting M dwarf stars, which were previously simulated by Domagal-Goldman et al. (2014) and Harman et al. (2015), by cosmic rays and lightning using results of experiments by Miyakawa et al. (2002) and Schlesinger and Miller ( 1983a , 1983b ). Stellar protons from active stars may be important energy sources for abiotic synthesis and increase production rates of biological compounds by at least 2 orders of magnitude compared to cosmic rays. Simple compounds such as HCN and H2CO are more readily synthesized than more complex ones, such as amino acids and uracil (considered here as an example), resulting in higher yields for the former and lower yields for the latter. Electric discharges are most efficient when a reducing atmosphere is present. Nonetheless, atmospheres with high quantities of CO2 are capable of producing higher amounts of prebiotic compounds, given that CO is constantly produced in the atmosphere. Our results further support planetary systems around M dwarf stars as candidates for supporting life or its origin.

PMID- 27700141 TI - Plasma Gelsolin Level in HIV-1-Infected Patients: An Indicator of Disease Severity. AB - Plasma gelsolin (pGSN) is a multifunctional protein involved mainly in severing and clearing of actin filaments. Its level correlates with inflammation and several diseases making it a potential biomarker of diagnostic and prognostic values. The pGSN level in groups of treated and untreated HIV-1-infected Indian patients is investigated in this study. This study aims at investigating the levels of pGSN in HIV-1-infected patients across different age, sex, severity of disease, and treatment status. Blood samples of 213 patients were analyzed for CD4 counts by flow cytometry and pGSN was quantified by enzyme-linked immunosorbent assay (ELISA). The level of pGSN is significantly increased in HIV 1 infected patients (227.2 +/- 54.3 MUg/ml) compared to healthy volunteers (167.9 +/- 61.8 MUg/ml). The level correlates with CD4 cell counts as patients with lower CD4 counts showed higher pGSN levels and vice versa. Gender does not affect pGSN level; however, antiretroviral (ARV) treatment reduces pGSN toward normal. Within low CD4 cell count group, the untreated patients have 52% higher pGSN than healthy volunteers, whereas with treatment, the difference reduces to 24%. Similarly, high CD4 cell count (>350 cells/mm3) group of patients showed 44% increase in pGSN in untreated patients compared to 21% increase in treated patients. There is an upregulation of pGSN in HIV-1 infection and it is inversely correlated with CD4 cell counts. Treatment with ARV drugs decreases pGSN levels toward normal. The monitoring of pGSN level in HIV-1-infected patients could be an important indicator of severity of disease and recovery during treatment. PMID- 27700140 TI - Vitamin D Deficiency and Metabolism in HIV-Infected and HIV-Uninfected Men in the Multicenter AIDS Cohort Study. AB - We evaluated associations of serum 25-hydroxyvitamin D (25[OH]D) and 1,25 dihydroxyvitamin D (1,25[OH]2D) levels in a cohort of HIV-infected and HIV uninfected men at risk for infection in the United States. Stored samples collected between 1999 and 2008 were tested for vitamin D metabolites between 2014 and 2015. Vitamin D deficiency was defined as a serum concentration of 25[OH]D <20 ng/ml. Multivariate models were used to assess associations of various demographic and clinical factors with vitamin D status. HIV-infected men on effective antiretroviral therapy (n = 640) and HIV-uninfected men (n = 99) had comparable levels of 25[OH]D and 1,25[OH]2D, and prevalences of vitamin D deficiency were 41% in HIV-infected and 44% in HIV-uninfected men, respectively. Self-reported black or other non-white race, obesity, and normal kidney function were significant predictors of vitamin D deficiency regardless of HIV serostatus. Lower CD4+ T cell count was associated with vitamin D deficiency in HIV-infected men, while current ritonavir use was protective. Self-reported black race was the only factor significantly associated with higher levels of 1,25[OH]2D (vs. whites; beta = 4.85 pg/ml, p = .003). Levels of 1,25[OH]2D and 25[OH]D were positively correlated in HIV-infected men (beta = 0.32 pg/ml, p < .001), but not in uninfected men (beta = -0.09 pg/ml, p = .623; p < .05 for interaction). Vitamin D deficiency was prevalent regardless of HIV serostatus in this cohort, suggesting that HIV infection did not confer additional risk of deficiency in this cohort of well-treated HIV-infected men. However, HIV infection and race may have implications for vitamin D metabolism and 1,25[OH]2D levels. PMID- 27700143 TI - William D. Cohen: Biologist, Educator, Editor (1938-2008). PMID- 27700144 TI - Clinician Perspectives on an Electronic Portal to Improve Communication with Patients and Families in the Intensive Care Unit. AB - RATIONALE: Communication in the intensive care unit (ICU) often falls short of patient and family needs, putting them at risk for significant physical and emotional harm. As electronic patient portals rapidly evolve, one designed specifically for the ICU might potentially enhance communication among patients, family members, and clinicians; however, the views of frontline ICU staff on such technology are unknown. OBJECTIVES: To identify clinician perspectives on the current state of communication among patients, families, and clinicians in the ICU, and assess their views on whether and how an electronic portal may address existing communication deficits and improve care. METHODS: Three focus groups comprised altogether of 26 clinicians from 6 ICUs, representing several disciplines in an academic medical center in Boston, Massachusetts. Transcripts were analyzed inductively for major themes using grounded theory. MEASUREMENTS AND MAIN RESULTS: We identified seven themes reflecting clinician perspectives on communication challenges and desired portal functionality: (1) comprehension and literacy; (2) results and updates; (3) patient and family preferences; (4) interclinician communication; (5) family informational needs; (6) the ICU as an unfamiliar environment; and (7) enhancing humanism through technology. Each theme included current gaps in practice, potential benefits and concerns related to an ICU communication portal, and participant recommendations. Benefits included enhanced education, patient/family engagement, and clinician workflow. Challenges included the stress and uncertainty of ICU care, fear of technology replacing human connection, existing interclinician communication failures, and the tension between informing families without overwhelming them. CONCLUSIONS: Overall, clinicians were cautiously supportive of an electronic portal to enhance communication in the ICU and made several specific recommendations for design and implementation. As new technologies expand opportunities for greater transparency and participation in care, clinician buy-in and positive impact will depend, in large part, on the extent to which the concerns of stakeholders are addressed. At the same time, clinicians anticipate several potential benefits that could help support provider workflow and engage patients and families through enhanced communication and humanism.

June Andrews discusses the radical legislative changes taking place in the NHS in Scotland this year. AB - The NHS is changing radically this year. It will affect the way nurses are paid, and the way they are held accountable. Education and training in the health service will differ across the UK, and laws may be passed that could mean people working in England pay more tax than those in Scotland. Why don't you know about it? If you live and work in Scotland, Wales, or Northern Ireland, you may well know. But this article is definitely for you if you live and work in England. PMID- 27700145 TI - Routine Antibiotic Prophylaxis Is Not Required for Patients Undergoing Shockwave Lithotripsy: Outcomes from a National Shockwave Lithotripsy Database in New Zealand. AB - PURPOSE: To assess the effectiveness of routine prophylactic antibiotics in the prevention of urinary tract infection (UTI) after extracorporeal shockwave lithotripsy (SWL) and identify predictors of UTI development in a multicenter series of over 10,000 stone cases treated in New Zealand over a 20-year period. MATERIALS AND METHODS: Patients treated with SWL on the Mobile Medical Technology vehicle between June 19, 1995 and December 1, 2014 were identified. Data collection was undertaken prospectively for patient, stone and treatment characteristics, and, retrospectively, for treatment outcomes. The primary outcome was clinical UTI, defined as development of UTI symptoms requiring antibiotic therapy. Secondary outcomes included urinary sepsis, need for hospital admission due to infectious complications, and length of hospital stay. Multivariate analysis was undertaken to identify factors independently associated with the development of post-SWL UTI. RESULTS: Antibiotic prophylaxis was used in 62.1% (n = 6710) of cases. On comparing patients who received prophylactic antibiotics to those in whom antibiotics were withheld, no significant differences were observed in terms of post-SWL UTI (1.1% vs 1.3%, p = 0.335) or urinary sepsis (0.04% vs 0.15%, p = 0.075). The use of prophylactic antibiotics was not independently associated with post-SWL UTI (OR: 1.269, 95% CI: 0.886 1.818, p = 0.194). Female gender, larger stone size, and higher number of delivered shocks were predictive of UTI development, but antibiotic prophylaxis did not appear to offer any benefit in this subgroup. CONCLUSIONS: Routine antibiotic prophylaxis was not associated with a reduction in clinical UTI after SWL in this cohort of over 10,000 stone cases in New Zealand. PMID- 27700148 TI - Frontliners.

They decided to investigate whether an involved grandmother affected use of services in the Royal Free Hospital A&E department. PMID- 27700154 TI - Pinpointing the problem of violence. AB - A recent rash of newspaper articles, a TV documentary and two consecutive hard hitting surveys have earned nursing the unenviable reputation of 'the most dangerous job in Britain'.While the profession has long recognised the gradual worsening of violent attacks in the workplace, the media furore in the press has left people demanding answers to some pertinent questions.

PMID- 27700164 TI - St Augustine's a South African trauma unit. AB - As a hospital resuscitation officer, I have a keen interest in all types of resuscitation to include trauma and prehospital care. My background is critical care nursing and I have undertaken the majority of advanced life support based courses, but like most of my colleagues our exposure to major trauma, especially penetrating trauma, is variable. Frimley Park Hospital is a 700 bedded district general hospital and our A&E department sees over 70,000 patients per year. On average, I will attend five clinical emergencies per week with the majority being medical. This mix of emergencies is common to all UK hospitals and even in large hospitals, such as The North Staffordshire Infirmary only 0.2 per cent of the work load is life-threatening injury ( Redmond 1997 ). The majority of UK trauma is blunt in origin and, although we tend to operate a system of trauma teams, there are still deficiencies in our care of trauma patients. I believe that part of the problem is lack of exposure. PMID- 27700167 TI - Use of liaison psychiatrists in A&E.

PMID- 27700178 TI - Uncut Esophagojejunostomy with Double Jejunal Pouch: An Alternative Reconstruction Method that Improves the Quality of Life of Patients after Total Gastrectomy. AB - BACKGROUND: Currently, there is no optimal digestive tract reconstruction technique well recognized by scholars after total gastrectomy. In this study, a new reconstruction method, which is modified from the classic Roux-en-Y procedure, an uncut jejunal esophageal anastomosis with double jejunal pouch (UJEA-DJP) was established, and its advantages for improving the quality of life of patients who undergo total gastrectomy were analyzed. METHODS: Altogether 160 patients with gastric cancer enrolled in our center from September 2009 to March 2012 received radical D2 total gastrectomy. According to the reconstruction methods used, these patients were divided into three groups: UJEA-DJP (n = 63), Roux-en-Y (n = 45), and P-loop with Roux-en-Y esophagojejunostomy (P-RY; n = 52). The operation time for reconstruction, complications, prognostic nutritional index (PNI), and the Visick classification among the three groups were analyzed. RESULTS: We found that UJEA-DJP has advantages over Roux-en-Y and P-RY regarding the time of digestive tract reconstruction, incidence rates for long-term complications, postoperative nutritional index, body weight recovery, and the Visick classification for subjective feelings (p < .05). CONCLUSIONS: The UJEA DJP surgical procedure has the advantages of intestinal continuity and double pouch construction, which can significantly reduce long-term complications and improve the long-term quality of life of patients after surgical procedure.

PMID- 27700180 TI - Acute biliary pancreatitis: focus on recurrence rate and costs when current guidelines are not complied. AB - BACKGROUND: International guidelines recommend cholecystectomy within 2-4 weeks after mild to moderate acute biliary pancreatitis (ABP) to prevent recurrence. We aimed to investigate the compliance to guidelines concerning early cholecystectomy and the associated costs. METHODS: Admissions for ABP 2011-2013 were retrospectively reviewed. Classification was made according to the revised Atlanta classification. Treatment, time to surgery and recurrence, as well as cost analysis for both in-hospital costs and loss of production (LOP) were performed. RESULTS: In total, 254 patients were included. Some 202 of the ABP patients (80%) underwent definitive treatment during their first attack of ABP (68% cholecystectomy, 17% endoscopic retrograde cholangiopancreatography (ERCP), 15% both interventions) and 186 (73%) were treated within 1 month of discharge. Patients with ERCP alone were significantly older than cholecystectomy cases (p < .001), but no significant difference was observed between those who underwent ERCP or no treatment (p = .071). Mild ABP had intervention earlier (p < .001). In all, 52 patients (20%) had no intervention, out of which 15 were readmitted due to pancreatitis, compared to 3 patients of those treated at the initial admission (p < .001). The mean cost for hospital care and LOP in mild ABP was ?6882 +/- 3010 and ?9580 +/- 7047 for moderate ABP (p = .001). The cost for a recurrent episode was ?16,412 +/- 22,367. CONCLUSION: By improved compliance to current guidelines concerning the management of ABP, recurrence rate and associated costs can potentially be reduced.

These health and social needs are numerous and complex. PMID- 27700181 TI - Laparoscopic-Assisted Percutaneous Endoscopic Gastrostomy Combined with CT-GC. AB - PURPOSE: Despite the widespread use of percutaneous endoscopic gastrostomy (PEG) tubes, their placement may be associated with a variety of complications, including gastrocolic fistula. MATERIALS AND METHODS: In total, seven high-risk individuals diagnosed using computed tomography (CT)-gastrocolonography (GC) underwent laparoscopic-assisted PEG (LAPEG) placement. Study endpoints included the success of LAPEG under local anesthetic and intravenous sedation, inability to thread the PEG tube, the eventual tube location, the number of tube adjustments needed, adverse events, the operating time, and PEG tube-related infection. RESULTS: In total, 135 PEG procedures were performed during this study. Successful CT-GC was achieved in all 135 patients, and we successfully used a standard PEG technique to place the gastrostomy tube in 128 patients (95%). In seven patients (5%), the LAPEG technique was used because the transverse colon became interposed between the abdominal wall and the anterior wall of the stomach. LAPEG procedure-related minor complications were observed in two patients. CONCLUSIONS: LAPEG combined with CT-GC can be used for patients with difficult anatomical orientations and may minimize the risk of complications in PEG placement. PMID- 27700184 TI - Frontliners.

PMID- 27700179 TI - Epigenetic control of the tumor microenvironment. AB - Stromal cells of the tumor microenvironment have been shown to play important roles in both supporting and limiting cancer growth. The altered phenotype of tumor-associated stromal cells (fibroblasts, immune cells, endothelial cells etc.) is proposed to be mainly due to epigenetic dysregulation of gene expression; however, only limited studies have probed the roles of epigenetic mechanisms in the regulation of stromal cell function. We review recent studies demonstrating how specific epigenetic mechanisms (DNA methylation and histone post-translational modification-based gene expression regulation, and miRNA mediated translational regulation) drive aspects of stromal cell phenotype, and discuss the implications of these findings for treatment of malignancies. We also summarize the effects of epigenetic mechanism-targeted drugs on stromal cells and discuss the consideration of the microenvironment response in attempts to use these drugs for cancer treatment.

PMID- 27700187 TI - An Update on Naltrexone/Bupropion Extended-Release in the Treatment of Obesity. AB - INTRODUCTION: As the prevalence of obesity continues to increase, the need for effective long-term treatment strategies for the overweight and the obese is critical. Pharmacology fills a large treatment gap between behavioral therapy, which is insufficient for the majority of patients, and devices and surgery, which are available to only a subset of patients. Naltrexone HCl and bupropion HCl Extended-Release (naltrexone XR/bupropion XR) was approved by the Food and Drug Administration for chronic weight management in 2014. Areas covered: This review illustrates the efficacy and safety of naltrexone XR/bupropion XR by examining data from clinical trials. It also provides an overview of the market and presents the pharmacodynamics and pharmacokinetics of naltrexone and bupropion. Expert opinion: The efficacy and safety profile of naltrexone XR/bupropion XR makes it a viable option for many patients who could benefit from its distinctive mechanism. The medication was shown to produce additive weight loss when combined with an intensive behavioral modification program and it may improve food cravings and eating behaviors. Compared to the other three antiobesity medications approved since 2012, naltrexone XR/bupropion XR is neither a controlled substance nor an injectable agent. PMID- 27700188 TI - New fixed dose chemical combinations: the way forward for better diabetes type II management? AB - INTRODUCTION: Diabetes type II is a complex disease with unclear pathophysiology. Lack of adherence and high cost of medicines invariably make the management of diabetes type II highly challenging. Newer fixed drug combinations (FDC) are cost effective and can improve the medication adherence thereby prevent the complications of diabetes. Safety and efficacy of newer FDCs are not well established in all populations. Moreover, extrapolating the efficacy and safety data globally may not be pragmatic. Our review will discuss newer chemical combinations available for the treatment of diabetes type II. Areas covered: In the present review, the authors discussed the newer FDCs available as add on therapy to the existing pharmacological interventions of diabetes type II that have shown promising results in various randomised trials with regard to efficacy and safety. Expert opinion: Safety and efficacy data of newer FDCs available as an adjuvant therapy to conventional pharmacological interventions in diabetes type II revealed that fewer new FDCs are promising with their high efficacy and low adverse effect. However, there is a need to explore the place in therapy to establish the utility of FDC in diabetes type II management. PMID- 27700189 TI - Differentiation of obese patients at moderate or higher Findrisc score based on their atherogenic index. AB - OBJECTIVES: The purpose of this study was to reveal different subgroups of patients with at least moderate risk of developing diabetes in the next 10 years, based on clustering of cardiovascular risk factors. METHODS: We performed a one center cross-sectional study of adult patients (n = 109, median age 45 years) with Findrisc score of above 11 out of 26 maximum. We included in the cluster analysis anthropometrics, lipid and carbohydrate parameters obtained in oral glucose tolerance test (OGTT), insulin, C-peptide, creatinine, C-reactive protein, liver enzymes, beta-cell function, insulin sensitivity and insulin resistance (HOMA calculations). We also evaluated the atherogenic index of plasma (AIP). RESULTS: We identified three metabolic phenotypes of patients with at least moderate Findrisc score-one 'male' (cluster AM, n = 24), and two 'female' phenotypes (cluster AW, n = 9 and cluster BW, n = 76). Men were almost homogenous for their metabolic phenotype, with lower fat percentage than women (p < .05). Most of the women (cluster BW, n = 76) presented with better metabolic pattern i.e. lower insulin resistance, lower C-reactive protein, lower degree of obesity and visceral fat rating (p < .05), despite the higher fat percentage (p < .05). Some of the women, however, (cluster AW, n = 9) presented with parameters very similar to that of men (cluster AM) and significantly higher than in cluster BW. Despite the lack of significant differences in lipid parameters among clusters, AIP was significantly lower in cluster BW (p < .05). CONCLUSION: Most of the women presented with clearly less unfavorable atherogenic risk than men. Two different phenotypes of obese women with at least moderate Findrisc score were revealed, and the level of inflammation seems to be the main discriminant factor. Larger prospective studies are required to elucidate whether those are really two different pathogenically phenotypes or if they belong to the same phenotype's continuum. PMID- 27700190 TI - Phenolics from Lagotis brevituba Maxim. AB - A phytochemical investigation on Lagotis brevituba led to the isolation and characterisation of 11 phenolic compounds: p-hydroxy-benzoic acid 1, methyl 3,4 dihydroxybenzoate 2, vanillic acid 3, protocatechuic acid 4, caffeic acid 5, glucose ester of (E)-ferulic acid 6, p-coumaric acid 7, vanillin 8, diosmetin-7-O beta-d-glucoside 9, chrysoeriol 10 and luteolin 11. Their structures were elucidated using spectroscopic methods and by comparison with data in the literature. Compounds 1-6 were first obtained from the genus Lagotis, and compounds 1-9 were isolated from L. brevituba for the first time. Compound 4 and 11 displayed remarkable antioxidant activities against DPPH radical (IC50 = 5.60 +/- 0.09, 27.5 +/- 0.06 mg/L, respectively), which were superior to positive control rutin. And compound 11 was also superior to rutin in ABTS assay (IC50 = 2.04 +/- 0.13 mg/L). PMID- 27700191 TI - Outcomes of Parathyroid Autotransplantation During Total Thyroidectomy: A Comparison with Age- and Sex-Matched Controls. AB - PURPOSE: To determine the effect of parathyroid autotransplantation (PA) on postoperative hypocalcemia in cases of total thyroidectomy. MATERIALS AND METHODS: Cases undergoing total thyroidectomy and PA were compared with age and sex-matched controls who had not undergone PA. The postoperative percentage changes (PC) of parathyroid hormone (PTH) and calcium (Ca+2) in the first 12-24 hours (12-24hr->preop), between the 1st-3rd weeks (1-3wk->preop) and at the 6th month (6mo->preop), the rates of hypocalcemia (Ca+2< 8mg/dL) and low PTH level (PTH< 15 pg/mL), permanent hypocalcemia, inadvertent parathyroidectomy in both groups were compared. RESULTS: The number of patients with PTH12-24hr<15 pg/mL was significantly higher (n:34,(55.7%)) than the number of patients in the control group (n:16(26.2%)), (p=0.001). The rate of decrease in the blood Ca+2 median PC (6mo->preop) was significantly higher in the PA group (4.2%) than the control group (1.1%), (p=0.008). There was no significant difference between the 2 groups in terms of the postoperative frequency of hypocalcemia (p>0.05). In the PA&age<=50 group, the rate of inadvertent parathyroidectomy was higher than that of cases over age 50 (p=0.029). CONCLUSION: In spite of the presence of an increased postoperative hypocalcemia trend in cases requiring PA during total thyroidectomy, the rates of transient and permanent hypocalcemia were not different to the control cases. But the frequency of cases with low PTH level in cases undergoing PA was higher than that of the control cases. In cases of 50 years of age and under, who had undergone PA, the possibility of inadvertent parathyroidectomy increased.

AB - OBJECTIVE: The aim of the study was to compare the safety effects of studded and unstudded winter tires based on fatal road accidents. METHODS: The data included 958 road accidents involving a passenger car or van that occurred in Finland from November to March between 1997 and 2012. RESULTS: Comparing the proportions of winter tire type in accidents and in general traffic showed that the overall effect of tire type on the number of accidents was not significant, although studded tires reduced fatal accidents by 10-15%. Compared to unstudded tires, studded tires reduced accidents significantly only on bald ice in 2005-2012. Drivers using unstudded tires were more experienced and their profession was more frequently related to driving. In addition, the vehicle age was lower for vehicles with unstudded tires. On the other hand, the state of repair was less pertinent for unstudded than for studded tires. These confounding factors offset their effects to some degree. CONCLUSIONS: The risk of fatal road accidents in winter between studded and unstudded tires does not differ significantly. However, the accident risk has recently been substantially higher on bald ice for unstudded than for studded tires. The magnitude of this risk difference is difficult to determine without specific information on exposure by road surface. PMID- 27700193 TI - Approaches for targeting cancer stem cells drug resistance. AB - INTRODUCTION: Several reports have suggested that a population of undifferentiated cells known as cancer stem cells (CSCs), is responsible for cancer formation and maintenance. In the last decade, the presence of CSCs in solid cancers have been reported. Areas covered: This review summarizes the main approaches for targeting CSCs drug resistance. It is indeed known that CSCs may contribute to resistance to conventional chemotherapy, radiotherapy and targeted agents. Among the mechanisms by which CSCs escape anticancer therapies, removal of therapeutic agents by drug efflux pumps, enhanced DNA damage repair, activation of mitogenic/anti-apoptotic pathways; the main features of CSCs, stemness and EMT, are involved, as well as the capability to evade immune response. Expert opinion: Different approaches are suitable to target CSCs mediated drug resistance. Some of them are currently under clinical evaluation in different cancer types. A better understanding of CSC biology, as well as more accurate study design, may maximize the therapeutic effects of these agents. In this respect, it is important to establish: (i) which molecules should be targeted; (ii) what drug combinations may be suitable; (iii) which patient settings will CSC targeting offer the highest clinical benefit; and (iv) how to integrate therapeutic approaches targeting CSCs with standard cancer therapy. PMID- 27700194 TI - Neurological abnormalities in localized scleroderma of the face and head: a case series study for evaluation of imaging findings and clinical course. AB - INTRODUCTION: Localized scleroderma (LoS) of the face and head is often associated with neurological manifestations and/or imaging abnormalities in the central nervous system (CNS). CASE SERIES: We present an analysis of 20 cases of LoS affecting the face and head. The CNS symptoms and/or abnormalities in high resolution computed tomography (HRCT) and/or magnetic resonance imaging (MRI) were observed in 12 patients (60%). In addition to the mild and unspecific disorders (e.g. headaches), serious neurological complications probably in the course of vasculitis were revealed: epilepsy (in two patients), epilepsy and pyramidal sings (in one patient). Neurological disorders and LoS occurred at the same time (in three patients) or at the course of the disease (nine patients) and no later than 29 years since the onset of the disease. No link between neurological disorders and the LoS clinical morphology, immunological and other laboratory parameters has been established. CONCLUSIONS: CNS involvement is not correlated with the clinical course of the facial and head LoS and may occur years after the disease initial symptomatology. Imaging follow-up is not required if there is not any emerging neurological symptom. In some cases, however, both HRCT and MRI are useful for monitoring disease evolution and addressing therapeutic choices. PMID- 27700195 TI - First-Night Effect on Sleep in Different Female Reproductive States. AB - OBJECTIVES: In sleep laboratory studies, the new environment is generally considered to disturb sleep during the first night. However, older women have rarely been studied. Although menopause and hormone therapy affect sleep, their impact on the first-night effect is virtually unknown. PARTICIPANTS: Four groups of women with no sleep laboratory experience: young on hormonal contraceptives (n = 11, 23.1 [0.5] years), perimenopausal (n = 15, 48.0 [0.4] years), postmenopausal without hormone therapy (HT; off-HT, n = 22, 63.4 [0.8] years) and postmenopausal with HT (n = 16, 63.1 [0.9] years). PROCEDURE: A cross-sectional study. METHODS: Polysomnography was performed over two consecutive nights and the first-night effect and group differences were evaluated. Questionnaire-based insomnia and sleepiness scores were correlated to sleep variables and their between-night changes. RESULTS: Although sleep in young women was deeper and less fragmented than in the other groups, first-night effect was similar in all study groups. Total sleep time, sleep efficiency, and S1 and S2 sleep increased, and wake after sleep onset, awakenings per hour of sleep, S2 and REM latencies, and percentage of SWS decreased from the first to the second night. Perimenopausal women had more insomnia complaints than other women. Insomnia complaints were associated with more disturbed sleep but not with the first-night effect. CONCLUSIONS: A first night in a sleep laboratory elicits a marked interference of sleep architecture in women of all ages, with a carryover effect of lighter sleep on the second study night. Menopausal state, HT use, or insomnia complaints do not modify this effect. PMID- 27700197 TI - Association appoints new RCN A&E Chair.

PMID- 27700196 TI - Pediatric Blunt Neck Trauma Causing Esophageal and Complete Tracheal Transection. AB - BACKGROUND: Blunt injuries to the cervical trachea remain rare but present unique and challenging clinical scenarios for prehospital providers. These injuries depend on prehospital providers either definitively securing the injured airway or bridging the patient to a treatment facility that can mobilize the necessary resources. CASE SUMMARY: The case presented here involves a clothesline injury to a pediatric patient that resulted in complete tracheal transection and partial esophageal transection. Ground and air prehospital providers utilized a stepwise approach to this airway injury and achieved a favorable outcome. The patient was serendipitously intubated through a blind nasal approach that entered the proximal esophagus, exited through the tear and entered the distal trachea. DISCUSSION: There is a paucity of literature describing the successful management of these devastating injuries. While some authors have advocated for early flexible fiberoptic intubation or proceeding directly to tracheostomy, these techniques are not available in the prehospital environment. This case also highlights the inherent issues with proceeding to cricothyroidotomy in patients with tracheal trauma and should give all providers pause before considering this management technique. CONCLUSION: Ultimately, a systematic approach to all airways will ensure that prehospital providers are best prepared for even the most challenging scenarios. PMID- 27700199 TI - Help wanted.

AB - Just as we are witnessing the re-emergence of Star Wars, it seems the 'turf wars' that have dogged A&E care are back. Since its inception as a specialty, A&E nurses have been accused of being 'Jacks (and Jill's, to be politically correct) of all trades and masters of none'. The inference being that all we do is 'mind' patients until they receive definitive care. Clearly this is not the case. As A&E nurses have demonstrated over the years, our skills are in the recognition and management of acute illness or injury, regardless of the patient's age, physical or psychological condition. Rather than being a 'master of none' we are masters of immediate care.

AB - I was one of those A&E nurses in the mid-eighties and early nineties who was committed to the concept of nurse triage as a means of providing better care for patients. I felt it was crucial for emergency nurses to recognise the importance of nurse triage and the part that they could play in its development. Estrada ( 1981 ) referred to 'non-professional triage' when patients were not seen and assessed by a nurse. She said of nurse triage that it was 'a professional judgment, made by a professional nurse'. PMID- 27700208 TI - First trimester serum levels of the soluble transcobalamin receptor, holo transcobalamin, and total transcobalamin in relation to preeclampsia risk. AB - BACKGROUND: Human placenta expresses CD320, a receptor that ensures the uptake of holo-transcobalamin (holoTC). Soluble CD320 (sCD320) is present in the circulation and its concentration increases during pregnancy. AIMS: To investigate a possible association of sCD320, holoTC and total transcobalamin (TC) with the risk of subsequent preeclampsia using serum samples from asymptomatic first trimester pregnant women. Moreover, we aimed to establish reference intervals of the aforementioned biomarkers for first trimester pregnant women who remained healthy throughout pregnancy. STUDY DESIGN: This study was a retrospective case-control study that we performed on biobank serum samples. Cases (n = 50) and controls (n = 198) (matched for gestational age and date of sample collection) were asymptomatic women in early pregnancy [median (range) gestational age = 10 (8-12) weeks]. Cases developed preeclampsia while the controls remained normotensive throughout pregnancy. We measured the serum concentration of sCD320, holoTC, and total TC by using in-house ELISA methods. RESULTS: First trimester median concentrations of sCD320, holoTC and total TC were not significantly different between cases and controls. The odd ratio for developing preeclampsia based on exposure to low or high levels of sCD320, holoTC or total TC at first trimester was not significant. The reference intervals (2.5 97.5% percentiles (median)) derived from the controls were 50-170 (90) pmol?L for sCD320, 20-140 (70) pmol?L for holoTC and 560-1300 (810) pmol?L for total TC. CONCLUSIONS: The risk of preeclampsia is not predicted by first trimester serum concentrations of sCD320, holoTC or total TC. The first trimester reference intervals for the three parameters is reported. PMID- 27700209 TI - Development of a Child Abuse Checklist to Evaluate Prehospital Provider Performance. AB - OBJECTIVES: To develop and provide validity evidence for a performance checklist to evaluate the child abuse screening behaviors of prehospital providers. METHODS: Checklist Development: We developed the first iteration of the checklist after review of the relevant literature and on the basis of the authors' clinical experience. Next, a panel of six content experts participated in three rounds of Delphi review to reach consensus on the final checklist items. Checklist Validation: Twenty-eight emergency medical services (EMS) providers (16 EMT Basics, 12 EMT-Paramedics) participated in a standardized simulated case of physical child abuse to an infant followed by one-on-one semi-structured qualitative interviews. Three reviewers scored the videotaped performance using the final checklist. Light's kappa and Cronbach's alpha were calculated to assess inter-rater reliability (IRR) and internal consistency, respectively. The correlation of successful child abuse screening with checklist task completion and with participant characteristics were compared using Pearson's chi squared test to gather evidence for construct validity. RESULTS: The Delphi review process resulted in a final checklist that included 24 items classified with trichotomous scoring (done, not done, or not applicable). The overall IRR of the three raters was 0.70 using Light's kappa, indicating substantial agreement. Internal consistency of the checklist was low, with an overall Cronbach's alpha of 0.61. Of 28 participants, only 14 (50%) successfully screened for child abuse in simulation. Participants who successfully screened for child abuse did not differ significantly from those who failed to screen in terms of training level, past experience with child abuse reporting, or self-reported confidence in detecting child abuse (all p > 0.30). Of all 24 tasks, only the task of exposing the infant significantly correlated with successful detection of child abuse (p < 0.05). CONCLUSIONS: We developed a child abuse checklist that demonstrated strong content validity and substantial inter-rater reliability, but successful item completion did not correlate with other markers of provider experience. The validated instrument has important potential for training, continuing education, and research for prehospital providers at all levels of training. PMID- 27700210 TI - Effects of Boron-Based Gel on Radiation-Induced Dermatitis in Breast Cancer: A Double-Blind, Placebo-Controlled Trial. AB - AIM: This study is aimed to evaluate the effects of boron on radiation-induced skin reactions (RISR) in breast cancer patients. MATERIAL AND METHODS: After 47 patients with invasive ductal carcinoma underwent radiotherapy, 23 (49%) received a boron-based gel, and 24 (51%) received placebo. Assessments were performed according to the Radiation Therapy Oncology Group (RTOG) skin scale and a Five Point Horizontal Scale (FPHS). RESULTS: At the end of the fifth week of radiotherapy, the RTOG scores in the boron group were significantly lower than those in the placebo group (p = .024). The FPHS score was higher in the placebo group than in the boron group, and this difference was not statistically significant (p = .079). CONCLUSION: Using the RTOG scoring system, we revealed that the application of a boron-based gel diminished RISR. The mechanism of action is unclear but may be related to antioxidant, wound healing, and thermal degradation effects of boron. PMID- 27700212 TI - New jobs.

AB - BACKGROUND: Chronic liver disease and cirrhosis are a leading cause of morbidity and mortality in the United States. Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis and which has been designated an orphan condition, is a chronic autoimmune disease resulting in the destruction of the small bile ducts in the liver. Without effective treatment, disease progression frequently leads to liver failure and death. Until May 2016, the only FDA approved treatment for PBC was ursodiol (UDCA), an oral hydrophilic bile acid, which can slow progression of liver damage due to PBC. However, 1 out of 3 patients taking UDCA has an inadequate biochemical response, leading to increased risk of disease progression, liver transplantation, and mortality. Given this unmet clinical need, new therapies are in development for the treatment of PBC. To provide pharmacists with an overview of the latest research on the pathophysiology of PBC and potential new treatment options and to highlight medical and specialty pharmacy approaches to managing access to drugs to treat orphan diseases such as PBC, a 2-hour satellite symposium was presented in conjunction with the 2015 Academy of Managed Care Pharmacy (AMCP) Nexus meeting. Although obeticholic acid was approved by the FDA for the treatment of PBC in May 2016, this development occurred after the symposium presentation. The symposium was supported by an independent educational grant from Intercept Pharmaceuticals and was managed by Analysis Group. Robert Navarro, PharmD, moderated the CPE accredited symposium titled "Medical and Specialty Pharmacy Management Update on Primary Biliary Cirrhosis." Expert panelists included Christopher L. Bowlus, MD; James T. Kenney, RPh, MBA; and Gary Rice, RPh, MS, MBA, CSP. OBJECTIVE: To summarize the educational satellite symposium presentations and discussions. SUMMARY: Autoimmune liver diseases, including PBC, are responsible for 15% of all liver transplants performed and an equal percentage of deaths related to liver disease. UDCA is the only FDA-approved therapy for treatment of PBC and is considered the standard of care. Nevertheless, many patients do not respond to UDCA, creating the need for new therapeutic options to improve clinical outcomes for PBC patients with inadequate response to treatment. While several agents are being studied in combination with UDCA, monotherapy with the novel agent obeticholic acid, a farnesoid X receptor agonist, has also shown promising results. Health plans are anticipated to assign any newly introduced therapy for the treatment of PBC to specialty pharmacy given its orphan disease status. This assignment enables the health plan to receive disease education, which is particularly important when new drugs are indicated for orphan diseases, and assistance with designing appropriate prior authorization criteria. The clinical value of any new therapeutic options that will inform formulary decisions and prior authorization criteria will be assessed based on evidence of efficacy, safety, and tolerability, among other factors, such as the potential to reduce or delay medical resource utilization (e.g., liver transplant). Key considerations for prior authorization of a new therapy will be determining which PBC patients are appropriate candidates for the new therapy and developing criteria for that determination. These are likely to include clinical diagnostic criteria and degree of response to prior treatment with UDCA. Initially, any new therapy would likely be positioned as noncovered until appropriate prior authorization criteria are established. CONCLUSIONS: PBC is a chronic liver disease with significant morbidity and mortality, as well as a significant burden on the health care system if the disease progresses to the point at which a liver transplant is needed. Although UDCA, the current standard of care, has improved outcomes for many patients, others have an inadequate response to this treatment. This symposium discussed these issues and also addressed the overall treatment paradigm for orphan drug therapies, key implications for patient management, and the role of specialty pharmacy management and any associated needs both in general and specifically for new therapeutic options for PBC.

PMID- 27700221 TI - Queuing for care. AB - THE NHS PLAN aims to move the NHS from the mid 20th century to the 21st century ( DoH 2000 ). It aims to change the culture of the NHS from a bureaucracy insensitive to the needs of people it serves, to one that is customer-focussed. This will involve radical changes to the NHS culture and it is unlikely that those changes can be implemented quickly ( Nazarko, 1996 ). It acknowledges the structural problems inherent in the NHS and aims to deliver a quality service. Does the NHS Plan give professionals the tools to deliver a quality service? How will other social policy initiatives help or hinder professionals in their efforts? Let us examine the potential benefits and pitfalls. PMID- 27700222 TI - Developing a learing culture. AB - A KEY ELEMENT to retaining and recruiting a nursing workforce is making sure that nurses are empowered to develop their practice and that they know their managers and other health professionals value their work. Although patients and relatives may well be effusive in their thanks to nurses, which in itself is an important aspect for job satisfaction, it is not enough. PMID- 27700223 TI - Steroid hormone receptors silence genes by a chromatin-targeted mechanism similar to those used for gene activation. AB - How genes are repressed by steroid hormones remains a matter of debate, and several indirect mechanisms have been proposed. We found that the ligand activated progesterone receptor recruits to the promoter of downregulated genes a repressor complex composed of HP1gamma, the lysine demethylase LSD1, histone deacetylases, coREST, the RNA SRA, and the ATPase BRG1. BRG1 is needed for chromatin remodeling and facilitates the deposition of linker histone variant H1.2, which compacts chromatin and hinders RNA polymerase loading and transcription. Thus, steroid hormone receptors can repress genes in ways reminiscent of those used for gene induction, namely by directly targeting factors that remodel chromatin. But while PR-dependent gene induction in T47D cells is mainly achieved by potentiating enhancer activity, repression acts at the level of gene promoters. PMID- 27700224 TI - Evidence-Based Treatment of Diabetic Retinopathy. AB - Diabetic retinopathy (DR) is the most frequent microvascular complication from diabetes and requires annual screening and at least annual follow-up. A systemic approach to optimize blood glucose and blood pressure may halt progression to severe stages of DR and obviate the need for ocular treatment. Although there is evidence of benefit from fenofibrate or intravitreous antiVEGF treatment for eyes with nonproliferative DR (NPDR), these therapies are not standard care for NPDR at this time. Some patients with severe NPDR, especially those with type 2 diabetes, benefit from early panretinal photocoagulation (PRP). Once DR progresses to proliferative DR (PDR), treatment is often necessary to prevent visual loss. PRP remains mainstay treatment for PDR with high-risk characteristics. However, intravitreous antiVEGF injections appear to be a safe and effective treatment alternative for PDR through at least two years. Vitreoretinal surgery is indicated for PDR cases with non-clearing vitreous hemorrhage and/or tractional retinal detachment.

AB - Microbe-to-plant signals can enhance the growth of a wide range of crops. The responses by soybean (Glycine max var. 91M01) to 2 signal molecules were investigated: Bradyrhizobium japonicum 532C lipo-chitooligosaccharide (Nod Bj V [C:18, MeFuc]) (LCO); and Bacillus thuringiensis strain NEB17 bacteriocin thuricin 17 (Th17). The objective was to assess and quantify the response by soybean, in terms of factors that contribute to yield, to the experimental signal molecules in germination experiments and field experiments. Soybean germination was stimulated by the experimental concentrations of Th17 under controlled 15 degrees C and 22 degrees C conditions, and 10-6 M LCO under 15 degrees C. There were negative relationships between Th17 concentration and both the number of trifoliate leaves and the dry weight of nodules: lower concentrations resulted in plants with more leaves and nodules while higher concentrations resulted in plants with fewer leaves and nodules. The 10-8 M LCO treatment had a significant effect on the dry weight of nodules at the flowering stage of plant development (F4,21 = 6.06, p = 0.0019). Considering the harvest stage data from both field trials of 2011, the lower experimental concentrations of Th17 resulted in taller plants. The study of Th17 has the potential to expand our understanding of this relatively recent and unexpected finding; and to understand how best to apply this finding, to allow increased production of soybean. Collectively, these results indicate that Th17 has potential in this regard. PMID- 27700228 TI - High-intensity interval training programme for obese youth (HIP4YOUTH): A pilot feasibility study. AB - Recently, there has been growing interest in high-intensity interval training (HIT) as a strategy to improve health. In this pilot study, we examined the feasibility of a 4-week low-volume HIT and its effects on cardiorespiratory fitness (CRF), blood pressure (BP) and enjoyment in overweight and obese youth. Twelve adolescents (body mass index (BMI): 34.8 +/- 3.9 kg . m-2, 14.9 +/- 1.5 years) participated in 12 sessions of HIT (10 * 60 s cycling bouts eliciting ~90% maximal heart rate, interspersed with 90 s recovery, 30 min/session, 3 sessions/week) over ~4 weeks. All the participants completed the study and exercise attendance averaged 92%. Despite no changes in body weight and total fat, HIT resulted in significant (P < 0.01) increases in CRF (pre: 20.1 versus post: 22.2 ml . kg-1 . min-1) and exercise time (pre: 425 versus post: 509 s) during peak oxygen uptake test, and a reduction in resting systolic BP (pre: 115.8 versus post: 107.6 mmHg). The majority of study participants (83%) enjoyed HIT and more than half of the participants (58%) reported that HIT is a more enjoyable form of exercise compared to other types of exercises. Low-volume HIT is a useful strategy to promote exercise participation and improve cardiovascular health in overweight and obese youth. PMID- 27700229 TI - Breast Cancer Heterogeneity: MR Imaging Texture Analysis and Survival Outcomes. AB - Purpose To determine the relationship between tumor heterogeneity assessed by means of magnetic resonance (MR) imaging texture analysis and survival outcomes in patients with primary breast cancer. Materials and Methods Between January and August 2010, texture analysis of the entire primary breast tumor in 203 patients was performed with T2-weighted and contrast material-enhanced T1-weighted subtraction MR imaging for preoperative staging. Histogram-based uniformity and entropy were calculated. To dichotomize texture parameters for survival analysis, the 10-fold cross-validation method was used to determine cutoff points in the receiver operating characteristic curve analysis. The Cox proportional hazards model and Kaplan-Meier analysis were used to determine the association of texture parameters and morphologic or volumetric information obtained at MR imaging or clinical-pathologic variables with recurrence-free survival (RFS). Results There were 26 events, including 22 recurrences (10 local-regional and 12 distant) and four deaths, with a mean follow-up time of 56.2 months. In multivariate analysis, a higher N stage (RFS hazard ratio, 11.15 [N3 stage]; P = .002, Bonferroni adjusted alpha = .0167), triple-negative subtype (RFS hazard ratio, 16.91; P < .001, Bonferroni-adjusted alpha = .0167), high risk of T1 entropy (less than the cutoff values [mean, 5.057; range, 5.022-5.167], RFS hazard ratio, 4.55; P = .018), and T2 entropy (equal to or higher than the cutoff values [mean, 6.013; range, 6.004-6.035], RFS hazard ratio = 9.84; P = .001) were associated with worse outcomes. Conclusion Patients with breast cancers that appeared more heterogeneous on T2-weighted images (higher entropy) and those that appeared less heterogeneous on contrast-enhanced T1-weighted subtraction images (lower entropy) exhibited poorer RFS.

PMID- 27700226 TI - LncRNAs: Bridging environmental sensing and gene expression. AB - The survival of all organisms is dependent on complex, coordinated responses to environmental cues. Non-coding RNAs have been identified as major players in regulation of gene expression, with recent evidence supporting roles for long non coding (lnc)RNAs in both transcriptional and post-transcriptional control. Evidence from our laboratory shows that lncRNAs have the ability to form hybridized structures called R-loops with specific DNA target sequences in S. cerevisiae, thereby modulating gene expression. In this Point of View, we provide an overview of the nature of lncRNA-mediated control of gene expression in the context of our studies using the GAL gene cluster as a model for controlling the timing of transcription. PMID- 27700231 TI - Frequency of Prosthetic Complications Related to Implant-Borne Prosthesis in a Sleep Disorder Unit. AB - Sleep bruxism and higher clench index have been associated with obstructive sleep apnea (OSA). However, there is no study that reports on the prosthetic complications in patients with OSA. Records of patients who had performed a sleep study to diagnose OSA were examined for the occurrence of prosthetic complications in implant-borne reconstructions. The primary outcome was the frequency of prosthetic complications. The secondary outcomes were anthropometric data, type of complication, type of prosthesis, type of retention, number of supporting implants, number of prosthetic units, and the presence of obstructive sleep apnea. Of the 172 patients, 67 had an implant-supported prosthesis, and all were included in the study. The mean age was 61 +/- 10 years, and 36 were female. Thirty complications in 22 prostheses were identified in 16 patients. The complications were porcelain fracture (14 events), screw/implant fracture (8 events), screw loosening (3 events), and decementation (5 events). The follow-up time was 117 +/- 90 months after placement of the prosthesis. The average time for complications to occur was 73 +/- 65 months after the placement of the prosthesis. According to the apnea-hypopnea index (AHI), 49 patients had OSA. Thirteen of the 16 patients having a prosthetic complication also had OSA. The highest AHI and thus the severity of OSA was identified in patients with a fracture complication related to an implant, a screw, or a porcelain. The frequency of prosthetic complications has been higher in patients with obstructive sleep apnea.

AB - Avian haemosporidian parasites provide a model system for understanding ecological and evolutionary host-parasite interactions. The diversity and distribution of these parasites remains incomplete, and, here, we provide the first range-wide assessment of avian haemosporidians in a continentally distributed host, the Northern Cardinal ( Cardinalis cardinalis ). Based on molecular techniques, we show geographical differences in prevalence and lineage diversity between host subspecies and identify several novel lineages. We use phylogenetic reconstruction to show where these lineages fit into the expanding evolutionary tree of avian haemosporidian lineages. All except 1 subspecies of Northern Cardinal are highly parasitized by a wide diversity of Plasmodium and Parahaemoproteus. Compared to published studies that used microscopy to determine prevalence in this host, we find a much higher number of infected individuals (67.4% vs. 45% or less). Consistent with previous studies, Parahaemoproteus from the Northern Cardinal was found to be highly host specific and geographically structured, whereas Plasmodium was less host specific and geographically unstructured.

Despite the vast volume of literature offering 'models of supervision' few give an operational definition of the concept ( Wolsey and Leach 1997 ). The majority of these models frame supervision within a psychotherapeutic model where a fixed amount of supervision, either one-to-one or in a group, meets the needs ofthe supervisee until the next meeting. The 'supervision session' becomes an almost mystical experience with little reference to day-to-day life in a busy health service.

In one respect she was right; journalists, either side of the border, do not understand devolution. In another respect she was wrong; the Welsh government, rather predictably, did package their health policy in much the same way as had been done in England, and our Welsh NHS Plan was launched earlier this month, supported by an additional L1billion over three years.

AB - Evidence is limited regarding the regional changes in spinal posture after self correction. The aim of the present study was to evaluate whether active self correction improved standing and sitting spinal posture. Photogrammetry was used to assess regional spinal curvatures and vertical global spine orientation (GSO) in 42 asymptotic women aged 20-24 years. Upper thoracic spine angle and GSO increased in response to self-correction, while the thoracolumbar and lumbosacral angles decreased. Self-correction in the standing position resulted in decreased inclination of the upper thoracic and thoracolumbar spinal angles. Correction of sitting posture reduced the angle of the upper thoracic spine and GSO. The effects of active self-correction on spinal curvature and GSO were different for the standing versus sitting position; the greatest effects of active correction were noted in the thoracic spine. Balanced and lordotic postures were most prevalent in the habitual and actively self-corrected standing positions, whereas the kyphotic posture was most prevalent in the habitual sitting position, indicative that self-correction back posture in the standing position could be an important health-related daily activity, especially during prolonged sitting.

AB - This study aimed to examine the association of social support, social factors, and maternal complications with caesarean deliveries in native and immigrant women, and to explore the association between acculturation and caesarean deliveries in immigrant women in Taiwan. This prospective panel study was conducted from August 2012 through April 2014 and included 222 native and 147 immigrant pregnant women in Taiwan. Caesarean rates did not differ significantly between native and immigrant women, including the overall caesarean rate (28.8%, 32.0%), medically indicated caesarean (22.5%, 24.5%), and caesarean without medical indications (6.3%, 7.5%). Results of multiple logistic regression models revealed that maternal complications and household activity support were positively associated with caesarean deliveries. Both native and immigrant women with high levels of informational support were less likely to receive caesareans. Immigrant women who were older than 35 years, had a middle level socioeconomic status, and perceived a high level of acceptance of caesarean in Taiwan were more likely to have caesarean deliveries. Informational support was a protective factor for caesarean delivery, whereas household activity support offered by the family was positively associated with caesarean delivery. Perceived acceptance level in mainstream society could affect immigrant women's use of caesarean delivery. PMID- 27700248 TI - Teaching and Learning in Medicine Volume 28, 2016.

Improving OSCE Checklists to Better Capture Performance in Progress Tests. AB - : Construct: The impact of using nonbinary checklists for scoring residents from different levels of training participating in objective structured clinical examination (OSCE) progress tests was explored. BACKGROUND: OSCE progress tests typically employ similar rating instruments as traditional OSCEs. However, progress tests differ from other assessment modalities because learners from different stages of training participate in the same examination, which can pose challenges when deciding how to assign scores. In an attempt to better capture performance, nonbinary checklists were introduced in two OSCE progress tests. The purposes of this study were (a) to identify differences in the use of checklist options (e.g., done satisfactorily, attempted, or not done) by task type, (b) to analyze the impact of different scoring methods using nonbinary checklists for two OSCE progress tests (nonprocedural and procedural) for Internal Medicine residents, and (c) to determine which scoring method is better suited for a given task. APPROACH: A retrospective analysis examined differences in scores (n = 119) for two OSCE progress tests (procedural and nonprocedural). Scoring methods (hawk, dove, and hybrid) varied in stringency in how they awarded marks for nonbinary checklist items that were rated as done satisfactorily, attempted, or not done. Difficulty, reliability (internal consistency), item-total correlations and pass rates were compared for each OSCE using the three scoring methods. RESULTS: Mean OSCE scores were highest using the dove method and lowest using the hawk method. The hawk method resulted in higher item-total correlations for most stations, but there were differences by task type. Overall score reliability calculated using the three methods did not differ significantly. Pass-fail status differed as a function of scoring methods and exam type, with the hawk and hybrid methods resulting in higher failure rates for the nonprocedural OSCE and the dove method resulting in a higher failure rate for the procedural OSCE. CONCLUSION: The use of different scoring methods for nonbinary OSCE checklists resulted in differences in mean scores and pass-fail status. The results varied with procedural and nonprocedural OSCEs.

PMID- 27700258 TI - Helping The Body To Cure Itself: Immune Modulation By Therapeutic Vaccination For Spinal Cord Injury. AB - Spinal cord injury often has devastating consequences, due to the poor regenerative capacity of the central nervous system (CNS), and because the injury triggers self-destructive processes that lead to degeneration of directly injured fibers, and fibers that survived the lesion but subsequently undergo "secondary degeneration." The highly complex, multifaceted dialogue between the immune system and the damaged spinal cord is complicated further by factors related to species, strain, and gender. It is suggested that following an injury to the CNS, the resident and systemic immune cells are recruited and activated, to reduce the self-destruction and facilitate the repair of the damaged nerve. Both of these functions can benefit from a well-controlled immune response that critically involves the innate and adaptive arms of the immune system, represented by macrophages/ microglia and autoimmune T cells, respectively. A poorly controlled immune response can be non-efficient or even destructive, leading in extreme cases even to autoimmune disease. The beneficial autoimmune response can be boosted by posttraumatic T cell-based vaccination with peptides that activate weak self-reactive T cells, thereby ensuring timely and adequate immune activation without the risk of autoimmune disease. It is proposed that the notion of "bad" or "good" inflammation be replaced by a concept that views inflammation in the CNS as a repair mechanism and thus as beneficial if well regulated, and supports therapy for spinal cord and other CNS injuries by immunomodulation.

AB - CASE DESCRIPTION A 6-year-old spayed female Golden Retriever was evaluated for a 2-week history of progressive hyporexia, signs of abdominal pain, and weight loss. CLINICAL FINDINGS Physical examination findings included mild signs of pain on palpation of the cranial part of the abdomen and a body condition score of 4 (scale, 1 to 9). A CBC revealed mild microcytosis and hypochromasia; results of serum biochemical analysis were within the respective reference ranges, and abdominal ultrasonography revealed no abnormalities. Capsule endoscopy was performed, and numerous gastric erosions and hemorrhages were detected, with rare dilated lacteals in the proximal aspect of the small intestine. TREATMENT AND OUTCOME Treatment was initiated with omeprazole and sucralfate for 6 weeks, and the dog was transitioned to a novel protein diet. Capsule endoscopy was repeated at the end of the initial treatment course and revealed overall improvement, with a few small erosions remaining; medical treatment was continued for an additional 2 weeks. At last follow-up 9 months after treatment ended, the dog was clinically normal. CLINICAL RELEVANCE Capsule endoscopy was useful for initial detection and subsequent reevaluation of gastrointestinal lesions in this patient without a need for sedation or anesthesia. Information obtained in the follow-up evaluation was valuable in identifying a need to extend the duration of medical treatment. PMID- 27700264 TI - Pathology in Practice. PMID- 27700265 TI - Rigid urethrocystoscopy via a percutaneous fluoroscopic-assisted perineal approach in male dogs: 19 cases (2005-2014). AB - OBJECTIVE To describe the technique and outcome for male dogs undergoing rigid urethrocystoscopy via a novel percutaneous, fluoroscopic-assisted perineal approach. DESIGN Retrospective case series. ANIMALS 19 client-owned male dogs. PROCEDURES Medical records of male dogs that underwent urethrocystoscopy via a percutaneous perineal approach for treatment of a variety of conditions from 2005 through 2014 were reviewed. Signalment, history, pertinent diagnostic imaging results, endourologic and postprocedure details, duration of hospitalization, complications, and outcome (short-term, < 1 month; long-term, >= 1 month) were recorded. After flexible urethrocystoscopy, direct percutaneous perineal needle puncture and guidewire placement by means of fluoroscopic guidance (with or without ultrasonography) allowed access to the urethral lumen. The perineal tract was subsequently serially dilated to accommodate a peel-away sheath and rigid endoscope. Rigid urethrocystoscopy was performed, and on completion of endourologic procedures, the access site was left to heal by second intention. RESULTS 19 male dogs successfully underwent 20 procedures. No intraoperative complications were reported. Short-term outcome was good (ie, mild perineal urine leakage) for 3 dogs and excellent (ie, no abnormalities with urination) for 16. Long-term outcome was excellent for the 17 dogs for which follow-up information was available. CONCLUSIONS AND CLINICAL RELEVANCE A percutaneous fluoroscopic assisted perineal approach (with or without ultrasonography) allowed access to the pelvic urethra with no major complications in the present series of patients. This minimally invasive approach may be a valuable tool for endourologic procedures in male dogs.

AB - OBJECTIVE To characterize the epidemiological, clinical, and echocardiographic features of dogs and cats with tetralogy of Fallot (TOF) and determine their survival times. DESIGN Retrospective case series. ANIMALS 15 dogs and 16 cats with a diagnosis of TOF as determined via echocardiography. PROCEDURES Medical records of dogs and cats were reviewed to extract information on signalment, clinical status at the time of TOF diagnosis, echocardiographic findings, and any outcome data. RESULTS The most common canine breeds were terrier types (n = 7). Most animals (28/31 [90%]) had clinical signs of TOF at the time of diagnosis, including cyanosis (16/31 [52%]). Pulmonic stenosis was characterized by a variable systolic Doppler-derived pressure gradient (median [range], 108 mm Hg [26 to 255 mm Hg]). Most ventricular septal defects were large, with a median (range) ratio of the diameter of the ventricular septal defect to that of the aorta of 0.60 (0.18 to 1.15). Median age at cardiac-related death was 23.4 months, with no significant difference between dogs and cats. Median survival time from TOF diagnosis to cardiac-related death was briefer for animals with no or low-grade heart murmur (3.4 months) than for those with higher-grade heart murmur (16.4 months). After adjustment for age and sex, having a lack of or a low to mild-grade systolic heart murmur was significantly associated with a briefer survival time. CONCLUSIONS AND CLINICAL RELEVANCE With a few exceptions, cardiac related death occurred predominantly in young adult dogs and cats with TOF, and most animals had severe clinical signs at the time of TOF diagnosis. PMID- 27700267 TI - Objective assessment of the compensatory effect of clinical hind limb lameness in horses: 37 cases (2011-2014). AB - OBJECTIVE To characterize and describe the compensatory load redistribution that results from unilateral hind limb lameness in horses. DESIGN Retrospective case series. ANIMALS 37 client-owned horses. PROCEDURES Medical records were reviewed to identify horses with unilateral hind limb lameness that responded positively (by objective assessment) to diagnostic local anesthesia during lameness evaluation and that were evaluated before and after diagnostic local anesthesia with an inertial sensor-based lameness diagnosis system. Horses were grouped as having hind limb lameness only, hind limb and ipsilateral forelimb lameness, or hind limb and contralateral forelimb lameness. Measures of head and pelvic movement asymmetry before (baseline) and after diagnostic local anesthesia were compared. The effect of group on baseline pelvic movement asymmetry variables was analyzed statistically. RESULTS Maximum pelvic height significantly decreased from the baseline value after diagnostic local anesthesia in each of the 3 lameness groups and in all horses combined. Minimum pelvic height significantly decreased after the procedure in all groups except the hind limb and contralateral forelimb lameness group. Head movement asymmetry was significantly decreased after diagnostic local anesthesia for horses with hind limb and ipsilateral forelimb lameness and for all horses combined, but not for those with hind limb lameness only or those with hind limb and contralateral forelimb lameness. CONCLUSIONS AND CLINICAL RELEVANCE Results supported that hind limb lameness can cause compensatory load redistribution evidenced as ipsilateral forelimb lameness. In this population of horses, contralateral forelimb lameness was not compensatory and likely reflected true lameness. Further studies are needed to investigate the source of the contralateral forelimb lameness in such horses. PMID- 27700268 TI - Overdiagnosis. PMID- 27700270 TI - Letters to the Editor.

AB - OBJECTIVE To identify risk factors associated with fatal injuries in Thoroughbred racehorses in the United States and Canada. DESIGN Retrospective study. ANIMALS 1,891,483 race starts by 154,527 Thoroughbred racehorses at 89 racetracks in the United States and Canada from 2009 to 2013. PROCEDURES Data were extracted from the Equine Injury Database, which contained information for 93.9% of all official flat racing events in the United States and Canada during the 5-year observation period. Forty-four possible risk factors were evaluated by univariate then multivariable logistic regression to identify those that were significantly associated with fatal injury (death or euthanasia of a horse within 3 days after sustaining an injury during a race). RESULTS 3,572 race starts ended with a fatal injury, resulting in a period incidence rate of 1.9 fatal injuries/1,000 race starts. Twenty-two risk factors were significantly associated with fatal injury. Risk of fatal injury was greater for stallions than for mares and geldings and increased as the number of previous nonfatal injuries and race withdrawals and level of competitiveness (eg, horse's winning percentage and race purse) of the horse or race increased. CONCLUSIONS AND CLINICAL RELEVANCE Results identified several risk factors associated with fatal injuries in Thoroughbred racehorses. This information can be used as a guideline for the identification of racehorses at high risk of sustaining a fatal injury and in the design and implementation of preventative measures to minimize the number of fatal injuries sustained by horses competing in flat racing in the United States and Canada.

Whereas NFL is known to be possible in any domain based on set theoretic concepts, probabilistic versions of NFL are presently believed to be impossible in continuous domains. This article develops a new formalization of probabilistic NFL that is sufficiently expressive to prove the existence of NFL in large search domains, such as continuous spaces or function spaces. This formulation is arguably more complicated than its set-theoretic variants, mostly as a result of the numerous technical complications within probability theory itself. However, a probabilistic conceptualization of NFL is important because stochastic optimization methods inherently need to be evaluated probabilistically. Thus the present study fills an important gap in the study of performance of stochastic optimizers. PMID- 27700278 TI - Introducing Elitist Black-Box Models: When Does Elitist Behavior Weaken the Performance of Evolutionary Algorithms? AB - Black-box complexity theory provides lower bounds for the runtime of black-box optimizers like evolutionary algorithms and other search heuristics and serves as an inspiration for the design of new genetic algorithms. Several black-box models covering different classes of algorithms exist, each highlighting a different aspect of the algorithms under considerations. In this work we add to the existing black-box notions a new elitist black-box model, in which algorithms are required to base all decisions solely on (the relative performance of) a fixed number of the best search points sampled so far. Our elitist model thus combines features of the ranking-based and the memory-restricted black-box models with an enforced usage of truncation selection. We provide several examples for which the elitist black-box complexity is exponentially larger than that of the respective complexities in all previous black-box models, thus showing that the elitist black-box complexity can be much closer to the runtime of typical evolutionary algorithms. We also introduce the concept of p-Monte Carlo black-box complexity, which measures the time it takes to optimize a problem with failure probability at most p. Even for small p, the p-Monte Carlo black-box complexity of a function class [Formula: see text] can be smaller by an exponential factor than its typically regarded Las Vegas complexity (which measures the expected time it takes to optimize [Formula: see text]).

AB - THE CONCEPT of shared governance, which originated in the USA in the 1970s, has recently been introduced into Britain ( Geoghegan and Farrington 1995 ). It developed as a means of allowing staff nurses to have greater control over their working environment (Totten and Scott 1993) and is widely recognised as having benefits in empowering practitioners from a variety of health care professions ( Porter O'Grady 1994 ). Several models of shared gov- ernance have been described in the literature (Porter-O'Grady 1994, Geoghegan and Farrington 1995), making it a broad philosophy which can be adapted to meet the needs of individual hospitals and health care trusts in the UK.

AB - A more horizontally oriented ground reaction force vector is related to higher levels of sprint acceleration performance across a range of athletes. However, the effects of acute experimental alterations to the force vector orientation within athletes are unknown. Fifteen male team sports athletes completed maximal effort 10-m accelerations in three conditions following different verbal instructions intended to manipulate the force vector orientation. Ground reaction forces (GRFs) were collected from the step nearest 5-m and stance leg kinematics at touchdown were also analysed to understand specific kinematic features of touchdown technique which may influence the consequent force vector orientation. Magnitude-based inferences were used to compare findings between conditions. There was a likely more horizontally oriented ground reaction force vector and a likely lower peak vertical force in the control condition compared with the experimental conditions. 10-m sprint time was very likely quickest in the control condition which confirmed the importance of force vector orientation for acceleration performance on a within-athlete basis. The stance leg kinematics revealed that a more horizontally oriented force vector during stance was preceded at touchdown by a likely more dorsiflexed ankle, a likely more flexed knee, and a possibly or likely greater hip extension velocity.

PMID- 27700374 TI - AtPAP2 modulates the import of the small subunit of Rubisco into chloroplasts. AB - Arabidopsis thaliana purple acid phosphatase 2 (AtPAP2) is the only phosphatase that is dual-targeted to both chloroplasts and mitochondria. Like Toc33/34 of the TOC and Tom 20 of the TOM, AtPAP2 is anchored to the outer membranes of chloroplasts and mitochondria via a hydrophobic C-terminal motif. AtPAP2 on the mitochondria was previously shown to recognize the presequences of several nuclear-encoded mitochondrial proteins and modulate the import of pMORF3 into the mitochondria. Here we show that AtPAP2 binds to the small subunit of Rubisco (pSSU) and that chloroplast import experiments demonstrated that pSSU was imported less efficiently into pap2 chloroplasts than into wild-type chloroplasts. We propose that AtPAP2 is an outer membrane-bound phosphatase receptor that facilitates the import of selected proteins into chloroplasts. PMID- 27700376 TI - Editorial.

AB - WHAT NURSING is and what nurses do can only be drawn from the information that they share in clinical communication. The information that surrounds the core of formal, organisational information is the informal 'professional' information of nursing. There is increased attention to information systems of paper and technology to meet accountability obligations and legal requirements. Much of the information attributing to the nurse's professional role is carried around 'in the head' with the result that nursing's professional information is either 'head held' or recorded on subsidiary notes. These issues give rise to challenges for nurse managers and leaders who could argue that the profession does need its informal information which should be captured within the organisation's system.

AB - Purpose The purpose of this paper is to present the application of logical framework analysis (LFA) for implementing continuous quality improvement (CQI) across multiple settings in a tertiary care hospital. Design/methodology/approach This study adopts a multiple case study approach. LFA is implemented within three diverse settings, namely, intensive care unit, surgical ward, and acute in patient psychiatric ward. First, problem trees are developed in order to determine the root causes of quality issues, specific to the three settings. Second, objective trees are formed suggesting solutions to the quality issues. Third, project plan template using logical framework (LOGFRAME) is created for each setting. Findings This study shows substantial improvement in quality across the three settings. LFA proved to be effective to analyse quality issues and suggest improvement measures objectively. Research limitations/implications This paper applies LFA in specific, albeit, diverse settings in one hospital. For validation purposes, it would be ideal to analyse in other settings within the same hospital, as well as in several hospitals. It also adopts a bottom-up approach when this can be triangulated with other sources of data. Practical implications LFA enables top management to obtain an integrated view of performance. It also provides a basis for further quantitative research on quality management through the identification of key performance indicators and facilitates the development of a business case for improvement. Originality/value LFA is a novel approach for the implementation of CQI programs. Although LFA has been used extensively for project development to source funds from development banks, its application in quality improvement within healthcare projects is scant. PMID- 27700473 TI - Social networks in health care teams: evidence from the United States. AB - Purpose The purpose of this paper is to synthesize existing evidence regarding health care team networks, including their formation and association with outcomes in various health care settings. Design/methodology/approach Network theory informed this review. A literature search was conducted in major databases for studies that used social network analysis methods to study health care teams in the USA between 2000 and 2014. Retrieved studies were reviewed against inclusion and exclusion criteria. Findings Overall, 25 studies were included in this review. Results demonstrated that health care team members form professional (e.g. consultation) and personal (e.g. friendship) networks. Network formation can be influenced by team member characteristics (i.e. demographics and professional affiliations) as well as by contextual factors (i.e. providers sharing patient populations and physical proximity to colleagues). These networks can affect team member practice such as adoption of a new medication. Network structures can also impact patient and organizational outcomes, including occurrence of adverse events and deficiencies in health care delivery. Practical implications Administrators and policy makers can use knowledge of health care networks to leverage relational structures in teams and tailor interventions that facilitate information exchange, promote collaboration, increase diffusion of evidence-based practices, and potentially improve individual and team performance as well as patient care and outcomes. Originality/value Most health services research studies have investigated health care team composition and functioning using traditional social science methodologies, which fail to capture relational structures within teams. Thus, this review is original in terms of focusing on dynamic relationships among team members. PMID- 27700474 TI - Assessing the relationship between patient satisfaction and clinical quality in an ambulatory setting. AB - Purpose The purpose of this paper is to assess the relationship between patient satisfaction and a variety of clinical quality measures in an ambulatory setting to determine if there is significant overlap between patient satisfaction and clinical quality or if they are separate domains of overall physician quality. Assessing this relationship will help to determine whether there is congruence between different types of clinical quality performance and patient satisfaction and therefore provide insight to appropriate financial structures for physicians. Design/methodology/approach Ordered probit regression analysis is conducted with overall rating of physician from patient satisfaction responses to the Clinician and Groups Consumer Assessment of Healthcare Providers and Systems survey as the dependent variable. Physician clinical quality is measured across five composite groups based on 26 Healthcare Effectiveness Data and Information Set (HEDIS) measures aggregated from patient electronic health records. Physician and patient demographic variables are also included in the model. Findings Better physician performance on HEDIS measures are correlated with increases in patient satisfaction for three composite measures: antibiotics, generics, and vaccination; it has no relationship for chronic conditions and is correlated with decrease in patient satisfaction for preventative measures, although the negative relationship for preventative measures is not robust in sensitivity analysis. In addition, younger physicians and male physicians have higher satisfaction scores even with the HEDIS quality measures in the regression. Research limitations/implications There are four primary limitations to this study. First, the data for the study come from a single hospital provider organization. Second, the survey response rate for the satisfaction measure is low. Third, the physician clinical quality measure is the percent of the physician's relevant patient population that met the HEDIS measure rather than if the measure was met for the individual patient. Finally, it is not possible to distinguish if the significant coefficient estimates on the physician age and gender variables are capturing systematic differences in physician behavior or capturing patient bias. Practical implications The results suggest patient satisfaction and physician clinical quality may be complementary, capturing similar aspects of overall physician quality, across some clinical quality measures but for other measures satisfaction and clinical quality are unrelated or negatively related. Therefore, for some clinical quality metrics, it will be important to separately compensate clinical quality and satisfaction and understand the relationship between metrics. Finally, the strong relationship between the level of patient satisfaction and physician age, physician gender, and patient age are important to consider when designing a physician compensation package based on patient satisfaction; if these differences reflect patient bias they could increase inequality among medical staff if compensation is based on patient satisfaction. Originality/value This study is the first to use physician organization data to examine patient satisfaction and physician performance on a variety of HEDIS quality metrics. PMID- 27700476 TI - Building a system-wide approach to community relationships with the findings of a scoping review in health and social care. AB - Purpose For leadership and management of Western health systems, good quality relationships are a fundamental cornerstone of organising health and social care (H&SC) delivery, delivering benefits across organisations and communities. The purpose of this paper is to explore the extant management, H&SC literature, grounded in older people care, reveal behaviours, processes and practices that if readily identified across a context will support healthy relationships across the "whole system" of stakeholders. Design/methodology/approach An academic/practitioner group designed and guided a scoping literature review of the H&SC and broader management literature to identify and extract important behaviours, processes and practices underlying the support of high-quality relationships. A search strategy was agreed and key health and management databases were interrogated and 51 papers selected for inclusion. Working with the practitioners, the selected papers were coded and then organised into emergent themes. Findings The paper outlines the relational behaviours, processes and practice elements that should be present within an older peoples care community, to support a healthy relational environment. These elements are presented under the five emergent literature themes of integrity, compassion, respect, fairness and trust. These five topics are examined in detail. A way forward for building statements using the review material, that may be applied to reveal relational patterns within older people care, is also explored and outlined. Research limitations/implications All literature reviews are subject to practical decisions around time, budget, scope and depth restraints. Therefore potentially relevant papers may have been missed in the review process. The scoping review process adapted here does not seek to make any major considerations with regards to the weighting of evidence behind the primary research. Originality/value This paper contributes to a growing need for designers of health systems to more fully understand, measure and draw on the value of relationships to help bridge the gap between diminishing resources and the expanding demand on H&SC services. PMID- 27700475 TI - Leadership and management in UK medical school curricula. AB - Purpose Although medical leadership and management (MLM) is increasingly being recognised as important to improving healthcare outcomes, little is understood about current training of medical students in MLM skills and behaviours in the UK. The paper aims to discuss these issues. Design/methodology/approach This qualitative study used validated structured interviews with expert faculty members from medical schools across the UK to ascertain MLM framework integration, teaching methods employed, evaluation methods and barriers to improvement. Findings Data were collected from 25 of the 33 UK medical schools (76 per cent response rate), with 23/25 reporting that MLM content is included in their curriculum. More medical schools assessed MLM competencies on admission than at any other time of the curriculum. Only 12 schools had evaluated MLM teaching at the time of data collection. The majority of medical schools reported barriers, including overfilled curricula and reluctance of staff to teach. Whilst 88 per cent of schools planned to increase MLM content over the next two years, there was a lack of consensus on proposed teaching content and methods. Research limitations/implications There is widespread inclusion of MLM in UK medical schools' curricula, despite the existence of barriers. This study identified substantial heterogeneity in MLM teaching and assessment methods which does not meet students' desired modes of delivery. Examples of national undergraduate MLM teaching exist worldwide, and lessons can be taken from these. Originality/value This is the first national evaluation of MLM in undergraduate medical school curricula in the UK, highlighting continuing challenges with executing MLM content despite numerous frameworks and international examples of successful execution. PMID- 27700477 TI - Building a learning health system using clinical registers: a non-technical introduction. AB - Purpose The purpose of this paper is to describe how clinical registers were designed and used to serve multiple purposes in three health systems, in order to contribute practical experience for building learning healthcare systems. Design/methodology/approach Case description and comparison of the development and use of clinical registries, drawing on participants' experience and published and unpublished research. Findings Clinical registers and new software systems enable fact-based decisions by patients, clinicians, and managers about better care, as well as new and more economical research. Designing systems to present the data for users' daily work appears to be the key to effective use of the potential afforded by digital data. Research limitations/implications The case descriptions draw on the experience of the authors who were involved in the development of the registers, as well as on published and unpublished research. There is limited data about outcomes for patients or cost-effectiveness. Practical implications The cases show the significant investments which are needed to make effective use of clinical register data. There are limited skills to design and apply the digital systems to make the best use of the systems and to reduce their disadvantages. More use can be made of digital data for quality improvement, patient empowerment and support, and for research. Social implications Patients can use their data combined with other data to self-manage their chronic conditions. There are challenges in designing and using systems so that those with lower health and computer literacy and incomes also benefit from these systems, otherwise the digital revolution may increase health inequalities. Originality/value The paper shows three real examples of clinical registers which have been developed as part of their host health systems' strategies to develop learning healthcare systems. The paper gives a simple non-technical introduction and overview for clinicians, managers, policy-advisors and improvers of what is possible and the challenges, and highlights the need to shape the design and implementation of digital infrastructures in healthcare services to serve users. PMID- 27700478 TI - Integrating research, clinical care, and education in academic health science centers. AB - Purpose One of the major issues faced by academic health science centers (AHSCs) is the need for mechanisms to foster the integration of research, clinical, and educational activities to achieve the vision of evidence-informed decision making (EIDM) and optimal client care. The paper aims to discuss this issue. Design/methodology/approach This paper synthesizes literature on organizational learning and collaboration, evidence-informed organizational decision making, and learning-based organizations to derive insights concerning the nature of effective workplace learning in AHSCs. Findings An evidence-informed model of collaborative workplace learning is proposed to aid the alignment of research, clinical, and educational functions in AHSCs. The model articulates relationships among AHSC academic functions and sub-functions, cross-functional activities, and collaborative learning processes, emphasizing the importance of cross-functional activities in enhancing collaborative learning processes and optimizing EIDM and client care. Cross-functional activities involving clinicians, researchers, and educators are hypothesized to be a primary vehicle for integration, supported by a learning-oriented workplace culture. These activities are distinct from interprofessional teams, which are clinical in nature. Four collaborative learning processes are specified that are enhanced in cross-functional activities or teamwork: co-constructing meaning, co-learning, co-producing knowledge, and co using knowledge. Practical implications The model provides an aspirational vision and insight into the importance of cross-functional activities in enhancing workplace learning. The paper discusses the conceptual and empirical basis to the model, its contributions and limitations, and implications for AHSCs. Originality/value The model's potential utility for health care is discussed, with implications for organizational culture and the promotion of cross functional activities. PMID- 27700528 TI - The effects of consecutive night shifts and shift length on cognitive performance and sleepiness: a field study. AB - INTRODUCTION: The aim of this study was to evaluate the effects of consecutive night shifts (CNS) and shift length on cognitive performance and sleepiness. MATERIALS AND METHODS: This study evaluated the sleepiness and performance of 30 control room operators (CROs) working in 7 nights, 7 days, 7 days off (7N7D7O) and 30 CROs working in 4 nights, 7 days, 3 nights, 7 days off (4N7D3N7O) shift patterns in a petrochemical complex on the last night shift before swinging into the day shift. To assess cognitive performance, the n-back test, continuous performance test and simple reaction time test were employed. To assess sleepiness, the Karolinska sleepiness scale was used. RESULTS: Both schedules indicated that the correct responses and response times of working memory were reduced (p = 0.001), while intentional errors and sleepiness increased during the shift work (p = 0.001). CNS had a significant impact on reaction time and commission errors (p = 0.001). CONCLUSION: The main duty of CROs at a petrochemical plant is checking hazardous processes which require appropriate alertness and cognitive performance. As a result, planning for appropriate working hours and suitable number of CNS in a rotating shift system is a contribution to improving CRO performance and enhancing safety.

We previously demonstrated that GPR40 signaling leads to cortical actin remodeling and potentiates the second phase of insulin secretion. In this study, we examined the role of p21 activated kinase 4 (PAK4), a known regulator of cytoskeletal dynamics, in GPR40-dependent potentiation of insulin secretion. The fatty acid oleate induced PAK4 phosphorylation in human islets, in isolated mouse islets and in the insulin secreting cell line INS832/13. However, oleate-induced PAK4 phosphorylation was not observed in GPR40-null mouse islets. siRNA-mediated knockdown of PAK4 in INS832/13 cells abrogated the potentiation of insulin secretion by oleate, whereas PAK7 knockdown had no effect. Our results indicate that PAK4 plays an important role in the potentiation of insulin secretion by fatty acids downstream of GPR40.

Most people in management have now gone through the process of either personally or organisation- ally seeing the impact of redundancy and premature retirement. Sometimes it is very sudden and people can feel aggrieved that they have not had the opportunity to say goodbye or good luck. It means that when you next meet the individual out shopping it is very difficult to know how to behave let alone what to say. But this social awkwardness does not compare to the situation when a colleague dies. PMID- 27700537 TI - Evolution of fungal population and mycotoxins in sorghum silage. AB - Silage, one of the most important feed sources for cattle, is vulnerable to contamination by spoilage moulds and mycotoxins because ensilage materials are excellent substrates for fungal growth. The aim of this study was to identify the mycobiota of sorghum silages, to determine the presence of aflatoxins and fumonisins, and to correlate these results with physical parameters of the silage. A total of 275 samples of sorghum were collected from dairy farms in the south-west region of Uruguay were silage practices are developed. The presence of fungi was observed in all of the sorghum samples with values varying from 0.2 * 104 to 4085 * 104 UFC g-1. Significant difference were detected in the total number of fungi during the storage period; at six months there is a high risk of fungal spoilage. The most frequent genera isolated from sorghum samples were Penicillium (70%), Aspergillus (65%), Absidia (40%), Fusarium (35%), Paecilomyces (35%) and Alternaria, Cladosporium, Gliocadium and Mucor (30%). The toxigenic species most frequently found were Penicillium citrinum, Aspergillus flavus and Fusarium nygamai. Only two samples were contaminated by AFB1 with levels of 1 and 14 ug kg-1. Fumonisin was detected in 40% of freshly harvest samples with levels ranged from 533 ug kg-1 to 933 ug kg-1. The use of silo bags seems to be an effective tool to store sorghum. However, the presence of toxigenic fungi show that regular screening for mycotoxins levels in silages must be performed to avoid the exposure of animals to contaminated feed and the introduction of these compounds into the food chain. PMID- 27700538 TI - Cross-Sex Hormone Treatment and Psychobiological Changes in Transsexual Persons: Two-Year Follow-Up Data. AB - CONTEXT: To date, there are few studies investigating the impact of body changes induced by cross-sex hormonal treatment (CHT) on psychobiological well-being in gender-dysphoric persons (GDs). OBJECTIVE: The objective of the study was to assess whether CHT-related body changes affect psychobiological well-being in GDs. METHODS: A consecutive series of 359 GDs was considered for a cross sectional section of the study. In addition, 54 GDs were studied in a 2-year follow-up. A physical examination was performed, including body mass index, waist circumference, and hair distribution. We also evaluated breast development and testis volume in male to female subjects and clitoris length in female to male. Subjects were asked to complete several psychometric measures for the assessment of body uneasiness, GD, and psychopathology levels. The evaluation was repeated 2 years prospectively. RESULTS: The following results were found: 1) GDs undergoing CHT reported significantly lower subjective levels of GD, body uneasiness, and depressive symptoms as compared with those without; 2) CHT-induced body modifications were significantly associated with a better psychological adjustment; 3) during CHT, GDs reported a significant reduction of general psychopathology, depressive symptoms, and subjective GD, whereas social and legal indicators of GD showed a significant increase across time; and 4) among body changes induced by CHT, only breast development and increased body mass index had a significant impact on psychopathology reduction across time in male to female subjects and female to male subjects, respectively. CONCLUSIONS: The aforementioned results support the efficacy of CHT intervention in improving subjective perception of one's own body, which was partially associated with objective changes. PMID- 27700539 TI - Is a Normal TSH Synonymous With "Euthyroidism" in Levothyroxine Monotherapy? AB - CONTEXT: Levothyroxine (LT4) monotherapy is the standard of care for hypothyroidism. OBJECTIVE: To determine whether LT4 at doses that normalize the serum TSH is associated with normal markers of thyroid status. DESIGN: Cross sectional data from the US National Health and Nutrition Examination Survey (2001 2012) was used to evaluate 52 clinical parameters. LT4 users were compared to healthy controls and controls matched for age, sex, race, and serum TSH. Regression was used to evaluate for correlation with T4 and T3 levels. PARTICIPANTS: A total of 9981 participants with normal serum TSH were identified; 469 were LT4-treated. RESULTS: Participants using LT4 had higher serum total and free T4 and lower serum total and free T3 than healthy or matched controls. This translated to approximately 15-20% lower serum T3:T4 ratios in LT4 treatment, as has been shown in other cohorts. In comparison to matched controls, LT4-treated participants had higher body mass index despite report of consuming fewer calories/day/kg; were more likely to be taking beta-blockers, statins, and antidepressants; and reported lower total metabolic equivalents. A serum TSH level below the mean in LT4-treated participants was associated with a higher serum free T4 but similar free and total T3; yet those with lower serum TSH levels exhibited higher serum high-density lipoprotein and lower serum low density lipoprotein, triglycerides, and C-reactive protein. Age was negatively associated with serum free T3:free T4 ratio in all participants; caloric intake was positively associated in LT4-treated individuals. CONCLUSIONS: In a large population study, participants using LT4 exhibited lower serum T3:T4 ratios and differed in 12/52 objective and subjective measures. PMID- 27700541 TI - New jobs. AB - ?

PMID- 27700540 TI - A SDHC Founder Mutation Causes Paragangliomas (PGLs) in the French Canadians: New Insights on the SDHC-Related PGL. AB - BACKGROUND: More than 40% of patients with paragangliomas (PGLs) harbor a germline mutation of the known PGL susceptibility genes, mainly in the SDHB or SDHD genes. OBJECTIVE: The objective of the study was to characterize the genetic background of the French Canadian (FC) patients with PGLs and provide new clinical and paraclinical insights on SDHC-related PGLs. METHODS: Genetic testing has been offered to FC patients affected with PGLs followed up at the adrenal genetics clinic at Centre hospitalier de l'Universite de Montreal. After genetic counseling, 29 FC patients consented for PGL genetic testing. RESULTS: Thirteen of 29 patients (44.8%) carried a germline mutation. The same heterozygous nonsense mutation at codon 133 of exon 5 of the SDHC gene (c.397C>T, p.[Arg133Ter]) was found in nine patients, representing 69.2% of the patients having a germline mutation. Seventy percent of these patients had head and neck PGLs. Twenty percent had multiple and 30% had malignant PGLs. We traced back the ascending genealogy of 10 index cases (nine patients from our cohort and one patient referred to us) and found that this mutation was most probably introduced in Nouvelle France by a couple of French settlers who established themselves in the 17th century. CONCLUSIONS: We found that 31% of the PGLs in the French Canadian can be explained by the SDHC mutation (c.397C>T, p.[Arg133Ter]). The dominance of the SDHC mutation is unique to the FCs and is most likely due to a French founder effect. SDHC gene analysis should be prioritized in FC patients with PGL.

AB - BRIAN SALMON was chairman of the Lyons Catering Company and one of the first businessmen to display an interest in the planning and delivery of a nationalised health service. As well as chairing the influential committee on nursing management, he was also chairman of Camden and Islington Area Health Authority between 1974 and 1977 and a supporter of nursing in general. His sad death earlier this year prompts a reevaluation of the legacy of the Salmon report, something that is already long overdue given the re-emergence under this government of many of the issues that the report considered. PMID- 27700543 TI - Editorial. AB - I have never seen an angrier nurse audience in my career. It was at the RCN's Congress this year. The anger was not, as might be imagined, expressed over one of the more contentious motions for debate. It occurred in a side room off the main corridor of the Old Swan Hotel in Harrogate, a setting sufficiently obscure for Agatha Christie to have hidden there for several weeks when there was a national search for her! The event was a meeting of senior nurses all involved with care in nursing homes. These are not happy times for such nurses. The money available for nursing home care is being ever further constrained by central government and many nursing homes are closing down, as their owners can no longer afford to subsidise public sector healthcare provision. But this was not the cause of the angst. PMID- 27700545 TI - Scottish agency reaches out.

AB - AS HEALTHCARE systems try to cope with wide-spread nursing shortages, nursing organisations and healthcare providers around the world are trying to recruit new candidates. They are beginning to consult with advertising agencies and public relations firms, most of whom know little or nothing about nursing. Unfortunately, many of these agencies tend to share stereotypical views of nurses who give direct care to the sick and vulnerable, and view the provision of traditional nursing services as dirty, menial, and disagreeable work. PMID- 27700553 TI - Back to basics. AB - PRIOR TO THE 1970s, clinical skills learned in pre-registration nurse education programmes were demonstrated and practised in the 'practical room'. Final assessments of competence consisted of student nurses being examined on their ability to prepare trolleys and trays to assist doctors. In the early 1970s, four practical-based assessments were introduced. These were conducted in the clinical environment by a named clinical assessor, usually the ward sister. Later, experiential learning was introduced whereby nursing students were expected to learn and develop these skills in the clinical environment, with clinical staff acting as teachers and assessors. As a consequence the practical room disappeared, along with the role of the clinical teacher. PMID- 27700554 TI - Monitoring ethnicity.

AB - No well-established evidences supporting the safe use of Bisphosphonates (BPs) or others antiresorptive agents prior, during or after dento-alveolar surgery, are currently available; moreover, the real risk of osteonecrosis of the jaw (ONJ) development is still unknown. The aim of the present systematic review was to assess the scientific literature concerning the implants placement in antiresorptive agents-users and the related risk of implants failure and ONJ development. English papers published from January 2003 until December 2014 were identified on Medline database. Titles and abstracts retrieved form electronic search were screened separately by two examiners; thus, original studies dealing with dental implants placement during or before bone antiresorptive agents therapy, and the relative risk of implant failure or development of osteonecrosis were evaluated. Due to the heterogeneity of the included studies and the high risk of bias, there is no evidence of the safe use of oral antiresorptive agents prior or after dental implant surgery. Indeed, implant failure and ONJ development can occur and represent a devastating side effect that should be considered during the treatment. Within the limitation of the present systematic review, high quality studies are needed to provide an adequate level of evidence regarding the safety of dento-alveolar surgery during or before bone resorption inhibition therapy, and the increase predisposition to osteonecrosis of the jaw (ONJ) development. Therefore, antiresorptive agents therapy should be considered a risk factor until further evidence is prospectively obtained. PMID- 27700617 TI - A novel one-step synthesis for carbon-based nanomaterials from polyethylene terephthalate (PET) bottles waste. AB - : Nowadays our planet suffers from an accumulation of plastic products that have the potential to cause great harm to the environment in the form of air, water, and land pollution. Plastic water bottles have become a great problem in the environment because of the large numbers consumed throughout the world. Certain types of plastic bottles can be recycled but most of them are not. This paper describes an economical solvent-free process that converts polyethylene terephthalate (PET) bottles waste into carbon nanostructure materials via thermal dissociation in a closed system under autogenic pressure together with additives and/or catalyst, which can act as cluster nuclei for carbon nanostructure materials such as fullerenes and carbon nanotubes. This research succeeded in producing and controlling the microstructure of various forms of carbon nanoparticles from the PET waste by optimizing the preparation parameters in terms of time, additives, and amounts of catalyst. IMPLICATIONS: Plastic water bottles are becoming a growing segment of the municipal solid waste stream in the world; some are recycled but many are left in landfill sites. Recycling PET bottles waste can positively impact the environment in several ways: for instance, reduced waste, resource conservation, energy conservation, reduced greenhouse gas emissions, and decreasing the amount of pollution in air and water sources. The main novelty of the present work is based on the acquisition of high value carbon-based nanomaterials from PET waste by a simple solvent-free chemical technique. Thus, the prepared materials are considered to be promising, cheap, eco-friendly materials that may find use in different applications.

PMID- 27700619 TI - Translating nanoparticulate-personalized cancer vaccines into clinical applications: case study with RNA-lipoplexes for the treatment of melanoma. AB - The development of nucleic acid based vaccines against cancer has gained considerable momentum through the advancement of modern sequencing technologies and on novel RNA-based synthetic drug formats, which can be readily adapted following identification of every patient's tumor-specific mutations. Furthermore, affordable and individual 'on demand' production of molecularly optimized vaccines should allow their application in large groups of patients. This has resulted in the therapeutic concept of an active personalized cancer vaccine, which has been brought into clinical testing. Successful trials have been performed by intranodal administration of sterile isotonic solutions of synthetic RNA vaccines. The second generation of RNA vaccines which is currently being developed encompasses intravenously injectable RNA nanoparticle formulations (lipoplexes), made up from lipid excipients, denoted RNA(LIP). A first product that has made its way from bench to bedside is a therapeutic vaccine for intravenous administration based on a fixed set of four RNA lipoplex drug products, each encoding for one shared tumor antigen (Lipoplex Melanoma RNA Immunotherapy, 'Lipo-MERIT'). This article describes the steps for translating these novel RNA nanomedicines into clinical trials. PMID- 27700620 TI - Earliest Evidence of Toxocara sp. in a 1.2-Million-Yr-Old Extinct Hyena (Pachycrocuta brevirostris) Coprolite from Northwest Pakistan. AB - The study of fossil parasites can provide insight into the antiquity of host parasite relationships and the origins and evolution of these paleoparasites. Here, a coprolite (fossilized feces) from the 1.2-million-yr-old paleontological site of Haro River Quarry in northwestern Pakistan was analyzed for paleoparasites. Micromorphological thin sectioning and Fourier-transform infrared spectrometry (FTIR) analysis confirms the coprolite belonged to a bone-eating carnivore, likely the extinct giant short-faced hyena (Pachycrocuta brevirostris). Parasitological analysis shows the coprolite to be positive for Toxocara sp. To our knowledge, this is the earliest evidence for Toxocara sp. found. PMID- 27700621 TI - Use of visual range measurements to predict fine particulate matter exposures in Southwest Asia and Afghanistan. AB - : Military personnel deployed to Southwest Asia and Afghanistan were exposed to high levels of ambient particulate matter (PM). However, quantitative ambient exposure data for conducting health studies are limited due to a lack of PM monitoring stations. Since visual range (VR) is proportional to particle light extinction, VR can serve as a surrogate for PM2.5 (particulate matter with an aerodynamic diameter <=2.5 um) concentrations. We used data on VR, relative humidity (RH), and PM2.5 ground measurements collected in Kuwait from years 2004 2005 to establish the relationship between PM2.5 and VR. Model validation obtained by regressing trimester average PM2.5 predictions against PM2.5 measurements in Kuwait produced an r2 value of 0.84. Cross validation of urban and rural sites in Kuwait also revealed good model fit. We applied this relationship to location-specific visibility data at 104 regional sites between years 2000-2012 to estimate monthly average PM2.5 concentrations. Monthly averages at sites in Iraq, Afghanistan, United Arab Emirates, Kuwait, Djibouti, and Qatar ranged from 10 to 365 ug/m3 during this period, while site averages ranged from 22 to 80 ug/m3, indicating considerable spatial and temporal heterogeneity in ambient PM2.5 across these regions. These data support the use of historical visibility data to estimate location-specific PM2.5 concentrations for application in epidemiological studies. IMPLICATIONS: This study demonstrates the ability to use airport visibility to estimate PM2.5 concentrations in Southwest Asian and Afghanistan. This supports the use of historical and ongoing visibility data to estimate PM2.5 exposure in this region of the world, where PM exposure information is otherwise scarce. This is of high utility to epidemiologists investigating the relationship between chronic exposure to PM2.5 and respiratory diseases among deployed military personnel stationed at various military bases throughout the region. Such information will enable the drafting of improved policies relating to military health.

AB - Aflatoxins, mainly produced by Aspergillus flavus and Aspergillus parasiticus, are highly toxic and may lead to health problems such as liver cancer. Exposure to aflatoxins may result from ingestion of contaminated foods. Levels of AFB1, AFB2, AFG1 and AFG2 in samples of groundnuts (Arachis hypogaea), beans (Phaseolus vulgaris), cowpeas (Vigna unguiculata) and bambara nuts (Vigna subterranean) grown by smallholder farmers in Shamva and Makoni districts, Zimbabwe, were determined at harvesting, using high performance liquid chromatography after immunoaffinity clean-up. Aflatoxins were detected in 12.5% of groundnut samples with concentrations ranging up to 175.9 ug/kg. Aflatoxins were present in 4.3% of the cowpea samples with concentrations ranging from 1.4 to 103.4 ug/kg. Due to alarming levels of aflatoxins detected in legumes versus maximum permissible levels, there is a need to assist smallholder farmers to develop harvest control strategies to reduce contamination of aflatoxins in legumes. PMID- 27700623 TI - Evaluation of the alteration of occlusal distribution in unilateral free-end and intermediate missing cases. AB - The present study aimed to evaluate the effect of implant prostheses on the occlusal force and area, and the distribution of occlusal loading in unilateral free-end and intermediate missing cases. Fourteen healthy subjects (7 free-end missing cases in the first and second molars and 7 intermediate missing cases in the first molar region) were included. Six months after the implant prosthesis was placed, an occlusal evaluation was performed with or without the implant superstructure by using Dental PrescaleA(r) film and an occluder device. In free end missing cases, the total occlusal force and area, implant-side occlusal force and area, and implant-side occlusal force and area of the residual natural teeth were significantly affected by the implant prostheses. In intermediate missing cases, the implant-side occlusal force of the residual natural teeth was significantly affected by the implant prostheses. In free-end missing cases, the proportion of implant-side occlusal force, non-implant-side occlusal force, and implant-side occlusal force of the residual natural teeth relative to the total occlusal force was significantly affected by the implant prostheses. In the intermediate missing cases, the proportion of the implant-side occlusal force of the residual natural teeth relative to the total occlusal force was significantly affected by the implant prostheses. The proportion of the occlusal area was also significantly affected. In free-end missing cases, implant prostheses significantly increased the occlusal force and area, which resulted in the proper occlusal distribution. In intermediate missing cases, an implant prosthesis may only improve the same-side occlusal loading of the natural teeth. PMID- 27700694 TI - Assessment of spatial variation of ambient volatile organic compound levels at a power station in Kuwait. AB - : Twenty-four-hour integrated ambient air samples were collected in canisters at 10 locations within Kuwait's major power station: Doha West Power Station to assess the spatial distribution of volatile organic compounds (VOCs) within the perimeter of the station. A total of 30 samples, i.e., three samples per location, were collected during February and March. The samples were analyzed using a gas chromatography with flame ionization detection (GC-FID) system and following the U.S. EPA Method TO-14A with modification. The results reflected the emission activities on the site and the meteorological conditions during sampling. Generally speaking, there was a negative correlation between the ambient temperature and the VOC concentrations, which indicates the sources were local. The halogenated compounds formed the highest proportion (i.e. 50-75 %) of the total VOC concentrations at the ten locations. 1,2,4-Trichlorobenzene and Vinyl Chloride concentrations were the highest amongst the other halogenated compounds. The aromatic compounds formed the least proportion (i.e. 1-4%) of the total VOC levels at all locations with Toluene having the highest concentrations amongst the aromatic compounds at seven locations. Propene, which is a major constituent of the fuel used, was the highest amongst the aliphatic compounds. The findings of this study and other relevant work suggests the measured VOC levels were the highest over the year, nevertheless, further work is required to assess the precisely temporal variation of VOC due to change in meteorological conditions and the emission rates. IMPLICATIONS: Assessment of VOC concentrations around a power plant in Kuwait during the peak season showed halogenated compounds to be the dominant group. The calculated indoor concentrations were lower than those reported in a residential area about 12 km away. PMID- 27700693 TI - Perspectives from health-care providers and women about completing human papillomavirus (HPV) self-testing at home. AB - Cervical cancer (CC) incidence and mortality rates are increased, and CC screening rates are low among Appalachian Ohio women. Mailing human papillomavirus (HPV) self-tests to women to complete at home is a potential new strategy to engage women in CC screening. The authors aimed to gain insights into the perceived acceptability of mailed HPV self-tests. Focus groups were conducted (August 2014-January 2015) among providers (physicians, nurse practitioners, nurses) and women in Appalachian Ohio. Providers (n = 28) and women (n = 15; age range: 32-62 years) reported general acceptance of HPV self-tests, however, for different reasons. Providers thought HPV self-testing would increase the proportion of under-screened women returning to the health-care system, while women thought self-testing would eliminate logistical and reduce psychological CC screening barriers. Findings provide insights into facilitators and barriers of completing an HPV self-test at home, returning it, reporting results, and providing needed follow-up care. To the authors' knowledge, no systematic research exists addressing providers' views regarding women's use of HPV self tests and the relation of such use to fostering subsequent Pap testing. This information will be useful in developing CC screening programs that include mailed HPV self-tests, as well as encouragement of follow-up Pap testing to meet existing CC screening guidelines. PMID- 27700696 TI - Enterococcus faecalis and Dental Implants. AB - Enterococcus faecalis appears in many tooth root infections and is not eliminated by root canal therapy. It can reside in tooth root canals and the surrounding bone. This species may vegetate in bone after extraction of an infected tooth and colonize a dental implant after placement in the healed site. A colonization may cause fixture loss or marginal bone loss. These colonizations are generally multibacterial and pathogenic properties can be shared via plasmids. However, E faecalis is not detectable with some culture techniques and thus can be missed. It is usually not a dominant species in these infections. Nonetheless, E faecalis may be a "keystone" player in dental implant bone loss or peri-implantitis. That is, E faecalis may be the pathogenic determinant for any particular peri implantitis infection of a multiple-species infection.

AB - The aim of this study was to determine the prevalence of osteoporosis and associated risk factors in Turkish women aged 18-49 years. A population-based, cross-sectional study was conducted between January and April 2014. The sample (n = 1,792) was comprised of women aged 18-49 years, who resided in Cubuk, Ankara, Turkey, and were selected by simple random sampling. The data were collected in face-to-face interviews using an Individual Information Form and an Osteoporosis Risk Estimation Scale. Bone mineral density was assessed using standard dual energy X-ray absorptiometry. Multiple logistic regression and chi-square analyses were used for analyses. Most participants (80.1%) were at low risk of developing osteoporosis, while 6.9% were at medium to high risk of developing the disease. From bone mineral density levels, 33.3% were osteopenic; 4.0% were osteoporotic; 33.3% were osteopenic at the femoral neck; and 6.7% were osteoporotic at the lumbar vertebra L1-L4. Further, results of multiple logistic regression analyses showed that osteoporosis risk was significantly associated with smoking, having light skin, multiparity, and having a family history of osteoporosis (p < .05). These results indicated that public health screening strategies for protecting women's bone health at earlier ages than previously thought might be beneficial. PMID- 27700697 TI - Body image as a target of victimization by peers/parents: Development and validation of the Body Image Victimization Experiences Scale. AB - This study developed and established the psychometric properties of the Body Image Victimization Experiences Scale (BIVES). The BIVES retrospectively assesses the frequency (Part A-frequency) and effect (Part B-impact) of victimization experiences pertaining to body image, perpetrated by peers and parents/caregivers in childhood and adolescence. Distinct samples of Portuguese women were recruited in 2013-2014: two nonclinical samples of the general population (n = 1,177), aged 18-60 years, and a clinical sample of patients with Binge Eating Disorder (BED; n = 73), aged 19-59 years. An exploratory factor analysis was conducted in 632 participants. A confirmatory factor analysis (CFA) and the scale's psychometric properties were tested in 545 participants. The ability of the BIVES to discriminate the clinical from a nonclinical sample was examined. The scale presented two factors indicating the sources of the victimization-peers and parents. CFA results confirmed the scale's structure. The BIVES presented very good internal consistency, construct and discriminant validity, good test-retest reliability, and was associated with related constructs, body image shame, and eating psychopathology. The scale adequately discriminated between the clinical sample and a nonclinical sample. The BIVES is a valid and reliable measure that allows for a comprehensive assessment of body image-related victimization experiences.

This has become a significant subject of inquiry in psychotherapeutic settings for the elderly and adolescents. However, the relationship between dance practice and correlates of psychological well-being, such as mindfulness and life satisfaction (LS)-two relevant indicators of mental health, has been explored relatively little in young women. The present study contrasted mindfulness and LS in young women (n = 81) who practiced dance regularly in three modern dance schools in the Province of Barcelona with a control group of non-practitioners (n = 120) studying at a university in Barcelona. The data were collected during the first semester of 2015, and the total sample had an average age of 20.88 +/- 3.36 years. Analyses of covariance showed higher levels of both mindfulness and LS in the dance practitioners, while a multiple regression analysis showed that, after controlling for age, dance was the factor most strongly associated with LS, explaining 28% of the variance in LS. These results are discussed in terms of the embodiment theory, and conclusions suggest that dance may be an effective gender focused practice to enhance well-being and promote mental health in young women.

AB - The diversity of protein targeting pathways to plastids and their regulation in response to developmental and metabolic status is a key issue in the regulation of cellular function in plants. The general import pathways that target proteins into and across the plastid envelope with changes in gene expression are critical for plant development by regulating the response to physiological and metabolic changes within the cell. Glycoprotein targeting to complex plastids involves routing through the secretory pathway, among others. However, the mechanisms of trafficking via this system remain poorly understood. The present article discusses our results in site-specific N-glycosylation of nucleotide pyrophosphatase/phosphodiesterases (NPPs) glycoproteins and highlights protein delivery in Golgi/plastid pathway via the secretory pathway. Furthermore, we outline the hypotheses that explain the mechanism for importing vesicles trafficking with nucleus-encoded proteins into plastids. PMID- 27700861 TI - Enhancing women's health: A call for social work research. AB - This article presents a critical synthesis of the social work empirical literature on women's health. In light of recent policy changes that directly affect women's health and social work, the authors conducted a literature review of recent publications (2010-2015) regarding social work and women's health nationally. Despite frequent accounts cited in the literature, there has been no comprehensive review of issues involving women's health and social work in the United States. The purpose of this review is to examine the current social work literature addressing women's health at the national (U.S.) level. This research presents a summary description of the status of the social work literature dealing with women's health, specifically 51 articles published between 2010 and 2015. Our search highlights the need for social work research to fill gaps and more fully address the needs of women across the lifespan.

Life is Precious (LIP), a community-based program in New York City, helps adolescents and families address risk factors facing Latinas. Participants are assessed for suicidal ideation, depressive and other psychiatric symptoms, and family functioning, at program entry and every 4 months during participation. Demographic characteristics and suicide attempts are also tracked. In the study period, there were no attempted or completed suicides in this high-risk population. Suicidal ideation, depressive symptoms, anger, and posttraumatic stress symptoms decreased significantly during participation. The LIP model shows promise for helping to address suicidal risk factors facing Latinas. However, in the absence of a comparison group, participants' improvement may be due to their engagement in mental health treatment more generally, or to the passage of time, rather than specifically to LIP. Nevertheless, as very little is known about how to address risk factors unique to Latina adolescents, these early findings may be of interest to the community serving Latina adolescents and the lessons may be of interest to programs serving adolescents from other racial/ethnic groups. Future research should develop comparison groups and test LIP implementation in other settings.

AB - OBJECTIVE: To identify factors affecting work-life balance amongst male and female orthodontists in the UK. DESIGN: A qualitative interview-based study with a cross-sectional design. SUBJECTS: Specialist orthodontists working in specialist practice and the hospital service in the UK were selected by purposive sampling. METHODS: In-depth semi-structured interviews were conducted with 18 orthodontic specialists. Interview transcripts were analyzed using Framework Analysis. RESULTS: Four main themes pertaining to work-life balance in orthodontics were identified: work factors affecting work-life balance, life factors affecting work-life balance, perception and effects of work-life balance and suggestions for managing work-life balance within the profession. CONCLUSIONS: There was substantial variation in the work-life balance of the orthodontists interviewed in this study; however the majority reported high levels of career satisfaction despite difficulties maintaining a good work-life balance. Whilst there were some clear distinctions in the factors affecting work life balance between the hospital environment and specialist practice (including additional professional commitments and teaching/training-related issues), there were also a number of similarities. These included, the lack of flexibility in the working day, managing patient expectations, taking time off work at short notice and the ability to work part-time. PMID- 27700909 TI - Knowing your face: A componential analysis of self-perceived facial attractiveness. AB - Facial attractiveness (FA) is a highly agreed upon and socially important characteristic, but contemporary research has not fully investigated individuals' enhancement of their FA. We used the social relations model (SRM) to analyze data from 187 participants. In face-to-face groups of four, participants rated their own and others' FA. We assessed the degree of FA enhancement using unconfounded measures of both self-insight and social comparison. Results indicated African Americans and men enhanced more than Caucasians and women. Race effects were mediated by psychological adjustment, while gender effects were related to meta perceptions. Men tended to view themselves through a "frog prince" lens, such that they accurately predicted others' lesser views of them but persisted in overly positive self-perceptions of FA. Findings suggest further consideration of SRM measures, meta-perceptions, and a focus on sample diversity in the study of self-enhancement. PMID- 27700910 TI - Exploring Homophobia in Tbilisi, Georgia. AB - The purpose of this study is to determine statistical predictors of homophobic attitudes among the residents of Tbilisi, Georgia. We analyze 2013 survey data from a representative sample of the Tbilisi adult population. Residents were asked about their attitudes, beliefs, and political and social values in the context of the May 17, 2013 attack on LGBT activists on the International Day Against Homophobia and Transphobia (IDAHOT). Findings show that homophobia is significantly predicted by male gender, lower levels of education, acceptance of social inequality, nonliberal attitudes, and perceiving homosexuals as a "threat to national security." However, psychological perceptions and personal experiences also indirectly influence homophobic attitudes: the findings suggest that males report homophobic attitudes more often than females do and tend to be even more homophobic when they believe that homosexuality is inborn rather than acquired. The study also found that people without liberal attitudes tend to be more homophobic when they have personal contacts with homosexuals. This article highlights the need for a more comprehensive approach to education and the promotion of liberal values as well as legal equality for LGBTQ individuals to decrease the level of homophobia in Georgian society and, specifically, in Tbilisi.

AB - Recent pension reforms in Norway mean that old-age pensions to a greater extent are a function of adaptations made and decisions made throughout the lifetime. How much you work, who you work for, when you retire, and how you invest will influence your standard of living as an old-age pensioner. This article investigates one important source of information about retirement and pension, namely service journalism in main national newspapers. How is the issue of pension framed in these articles? And what kind of advice is presented by which kind of actors? Findings indicate that service journalism is dominated by pension industry sources, and old-age pension is framed as a function of individual investment choices rather than as citizens' rights.

AB - KEY FINDINGS: *The teen birth rate declined to another historic low for the United States in 2015, down 8% from 2014 to 22.3 births per 1,000 females aged 15 19. *The birth rates for teenagers aged 15-17 and 18-19 declined in 2015 to 9.9 and 40.7, respectively, which are record lows for both groups. *In 2015, birth rates declined to 6.9 for Asian or Pacific Islander, 16.0 for non-Hispanic white, 25.7 for American Indian or Alaska Native, 31.8 for non-Hispanic black, and 34.9 for Hispanic female teenagers aged 15-19. *Birth rates fell to record lows for nearly all race and Hispanic-origin groups of females aged 15-19, 15-17, and 18 19 in 2015. The birth rate for teenagers aged 15-19 has fallen almost continuously since 1991, reaching historic lows for the nation every year since 2009 (1-4). Despite declines in all racial and ethnic groups, teen birth rates continue to vary considerably by race and ethnicity. Moreover, the U.S. teen birth rate remains higher than in other industrialized countries (5). Childbearing by teenagers continues to be a matter of public concern. This report presents the recent and long-term trends and disparity in teen childbearing by race and Hispanic origin. PMID- 27700965 TI - Editorial.

AB - Fractures are associated with morbidity and mortality. Individuals with chronic kidney disease (CKD) experience bone mineral metabolism changes, which increases fracture risk. Researchers have quantified the epidemiology of fractures in adults with CKD using administrative health databases from Ontario, Canada, held at the Institute for Clinical Evaluative Sciences. Results demonstrated that many individuals with non-transplant CKD sustain fractures, with the risk increasing as kidney function declines. However, fracture risk in kidney transplant recipients was lower than previously described, which suggests recipients may not be a high-risk fracture group. There is a need to test fracture prevention interventions in the CKD population. PMID- 27700968 TI - The Challenge Before Us.

AB - Good primary care is essential for the effective management of patients with chronic conditions in the community and to ensure their care is well coordinated with other parts of the system. The Commonwealth Fund 2015 International Health Policy Survey compares the views and experiences of primary care physicians in 11 countries including Canada. The survey found nearly all (98%) primary care doctors across countries treat patients with complex needs in their practice. However, when examining questions on chronic disease management and coordination of care with other providers, Canadian results are mixed compared to the international average, and show variation at the provincial level. Opportunities likely exist to learn from other countries that have a more systematic approach to primary care delivery. PMID- 27700969 TI - What Gets in the Way of Person-Centred Care for People with Multimorbidity? Lessons from Ontario, Canada. AB - Person-centred care is becoming a key component of quality in health systems worldwide. Although the term can mean different things, it typically entails paying attention to the needs and background of health system users, involving them in decisions that affect their health, assessing their care goals and implementing a coordinated plan of care that aligns with their unique circumstances. The importance of practising a person-centred approach in care delivery dominates policy and research rhetoric worldwide, yet competing goals set by policy planners to save money, eliminate waste and sustain the healthcare system challenge the implementation of such an approach. In this commentary, we begin by exploring the concept of person-centred care and its importance among people who frequently use healthcare, such as those with multimorbidity. We then provide a brief overview of the evolution of Ontario's healthcare system and its emphasis on achieving cost savings. In doing so, we illustrate the implications for health system users, particularly people with multimorbidity, their carers and formal care providers. Finally, we reflect on examples of innovations that are striving to deliver person-centred care, despite a constrained healthcare environment. While a step in the right direction, we conclude that these "one off" strategies are unsustainable in the absence of supporting policy levers. PMID- 27700970 TI - Understanding Clinical Complexity the Hard Way: A Primary Care Journey. AB - Ten years ago, complexity was not a term often used in primary care. In the last decade, however, the population seen in primary care has shifted, posing substantial challenges for both primary care providers and health systems. In this essay, I will document the approaches that evolved in an academic family practice environment to address the challenges posed by complex patients typified by multiple concurrent chronic conditions and social determinants challenges. I will describe the research that lead to the creation, implementation and evaluation of an inter-professional model of care and associated outcomes. I will describe how this work subsequently led to the evolution of clinical models and research projects designed to reframe the discourse around complexity as well as move forward on elaborating new policy, clinical and service delivery innovations. I will conclude with some thoughts about what I see as the major challenges in the short and immediate term for research and practice, drawing on 15 years of practice and research experience with complex populations. PMID- 27700971 TI - eHealth Advances in Support of People with Complex Care Needs: Case Examples from Canada, Scotland and the US. AB - Information technology (IT) in healthcare, also referred to as eHealth technologies, may offer a promising solution to the provision of better care and support for people who have multiple conditions and complex care needs, and their caregivers. eHealth technologies can include electronic medical records, telemonitoring systems and web-based portals, and mobile health (mHealth) technologies that enable information sharing between providers, patients, clients and their families. IT often acts as an enabler of improved care delivery, rather than being an intervention per se. But how are different countries seeking to leverage adoption of these technologies to support people who have chronic conditions and complex care needs? This article presents three case examples from Ontario (Canada), Scotland and Kaiser Permanente Colorado (United States) to identify how these jurisdictions are currently using technology to address multimorbidity. A SWOT (strengths, weaknesses, opportunities, threats) analysis is presented for each case and a final discussion addresses the future of eHealth for complex care needs. The case reports presented in this manuscript mark the foundational work of the Multi-National eHealth Research Partnership Supporting Complex Chronic Disease and Disability (the eCCDD Network); a CIHR-funded project intended to support the international development and uptake of eHealth tools for people with complex care needs. PMID- 27700972 TI - Applying Clinical Practice Guidelines to the Complex Patient: Insights for Practice and Policy from Stroke Rehabilitation. AB - In Canada, policy makers are working to align services with the Stroke Rehabilitation Best Practice Recommendations (SRBPR). Complicating the application of clinical practice guidelines (CPGs) is the fact that most strokes occur in the context of other diagnoses. We sought to understand clinicians' use of the CPGs and ascertain how much guidance regarding multimorbidity was available in the SRBPR. Study results indicated that using the recommendations was problematic due to a perceived lack of guidance regarding comorbidities and multimorbidity, and concerns regarding the applicability to "real-life patients." Comorbidities were mentioned in less than half of the recommendations, but no explicit guidance was provided regarding the management of comorbidities. Given the prevalence of multimorbidity in stroke rehabilitation, this clinical context is ideal for development and testing of CPGs that account for multimorbidity and other complexity factors. Results may also suggest limitations to using CPGs in the development of activity-based funding models. PMID- 27700973 TI - Performance Measurement for People with Multimorbidity and Complex Health Needs. AB - This paper reviews approaches to performance measurement in health systems with particular attention to people with multimorbidity and complex health needs. Performance measurement should be informative and used by multiple stakeholders in order to align performance improvement efforts. System performance measures must allow for macro-system and meso-organization and provider-level reporting, and they should be relevant and important to stakeholders at each level, as well as to patients and all potential care recipients. Measures that assess health outcomes and individuals' experiences with providers, including care planning and coordination of care across providers, are essential to assess value for people with multimorbidity and complex health needs. I suggest that performance measurement for this population should be motivated by the Complexity Framework and organized by the Triple Aim. Based on the care needs and appropriate goals for the health system for this population, applicable measures and suggestions for implementing and using performance measurement systems are identified. Particularly in the case of people with multimorbidity and complex health needs, performance measures must move beyond measures specific to individual encounters to track care for people over time and space. Measures must be rooted in individuals' own needs and goals for care. New systems are required to enable collection and reporting of these measures.

AB - In today's demographic landscape, with its aging population and increasing number of individuals who are living with multiple chronic conditions and comorbidities, the healthcare system is tasked with responding to the needs of medically complex individuals. However, the pressures arising from this emerging demographic are felt not only within the acute care sector at the point of medical crisis but along the entire continuum of the healthcare system. Rehabilitative care plays a key role in that continuum by providing the process through which individuals are engaged in interventions to address their functional (both cognitive and physical) and psychosocial care goals to help them carry on with the business of living.

AB - Integrating care for people with complex needs is challenging. Indeed, evidence of solutions is mixed, and therefore, well-designed, shared evaluation approaches are needed to create cumulative learning. The Toronto-based Building Bridges to Integrate Care (BRIDGES) collaborative provided resources to refine and test nine new models linking primary, hospital and community care. It used mixed methods, a cross-project meta-evaluation and shared outcome measures. Given the range of skills required to develop effective interventions, a novel incubator was used to test and spread opportunities for system integration that included operational expertise and support for evaluation and process improvement. PMID- 27700977 TI - A "Simple" Evidence-Based Intervention to Improve Care Transitions for Frail Patients with Complex Health Conditions: Why Didn't It Work as Expected? AB - The transition from hospital to home is a vulnerable period for patients with complex conditions, who are often frail, at risk for adverse events and unable to navigate a system of poorly coordinated care in the post-discharge period. Care transition interventions are seen as effective care coordinating mechanisms for reducing avoidable adverse events associated with the transition of the patient from the hospital to the home. A study was undertaken to evaluate the effectiveness of a care transition intervention involving a hand-off between a hospital-based care transitions nurse and a community-based rapid response nurse. Two focus groups were held, one involving rapid response nurses and the other involving care transition nurses. Individual interviews were conducted with the managers (n = 2) and executives (n = 2) to identify the factors that facilitated or were barriers to its implementation. Using thematic content analysis, it was found that the effectiveness of transitional coordination efforts was thwarted by ineffective communication, which affected the quality of the underlying relationships between the two teams. Other barriers to achieving the desired outcomes included the following: issues of role clarity, role awareness and acceptance, the adequacy and reinforcement of coordinating mechanisms, the effectiveness of the information exchange protocols and the absence of shared measures of accountability. Clinical integration initiatives have fewer human resource and financial implementation barriers compared with organizational integration efforts but are complex undertakings requiring clear alignment between organizations, shared accountability measures, effective communication processes and relationships of trust and respect between interprofessional teams.

AB - The present study aimed to describe serum anti-Mullerian hormone (AMH) patterns of ex situ male and female beluga to examine the influence of age (divided into 5 year categories) or sexual maturation and reproductive season. In males aged 5-9 years, AMH concentrations were significantly (P<0.05) higher than those in all age categories exceeding 15 years and were not influenced by season (P=0.57). AMH concentrations in females peaked in the 5-9-year age category during the breeding season and decreased (P<0.05) after 9 years of age. Aged females displayed lower (P<0.05) AMH concentrations than immature and mature animals and immature females secreted higher concentrations than mature animals (P=0.03). For mature females, seasonal differences (P=0.02) in AMH concentrations were detected, with females in the breeding season displaying higher AMH concentrations than in the non breeding season. This is the first time AMH has been characterised in a cetacean species and the first potential hormonal evidence of reproductive senescence in beluga. Further research is required to determine if this hormone can be used as a predictor of fertility for the species. PMID- 27700982 TI - A combination of insulin-like growth factor I (IGF-I) and FSH promotes proliferation of prepubertal bovine Sertoli cells isolated and cultured in vitro. AB - Beef and dairy bull calves fed a low-nutrition diet during early life had decreased concentrations of circulating insulin-like growth factor I (IGF-I), delayed increases in testosterone, smaller testes and delayed puberty compared with those fed high-nutrition diets. Although IGF-1 has important roles in Sertoli cell function in rats and mice, this has not been well documented in bulls. The objectives of this study were to: (1) isolate Sertoli cells from bull calves at 8 weeks of age, (2) culture them in vitro and (3) determine the effects of IGF-I, FSH and a combination of both hormones on cell proliferation. For Sertoli cell isolation, minced testicular tissues were treated with collagenase followed by trypsin and hyaluronidase to digest seminiferous tubules and release Sertoli cells. In this study, Sertoli cells were successfully isolated from 8 week-old Holstein bull calves (n=4) and these cells were cultured for up to 8 days. A combination of IGF-I and FSH increased proliferation (~18%) and therefore cell number (1.5-fold) of prepubertal bovine Sertoli cells in culture, providing clear evidence that IGF-I has a similar role in bovine Sertoli cells as reported in rodents.

AB - Feral horses are a significant pest species in many parts of the world, contributing to land erosion, weed dispersal and the loss of native flora and fauna. There is an urgent need to modify feral horse management strategies to achieve public acceptance and long-term population control. One way to achieve this is by using non-surgical methods of sterilisation, which are suitable in the context of this mobile and long-lived species. In this review we consider the benefits of implementing novel mechanisms designed to elicit a state of permanent sterility (including redox cycling to generate oxidative stress in the gonad, random peptide phage display to target non-renewable germ cells and the generation of autoantibodies against proteins essential for conception via covalent modification) compared with that of traditional immunocontraceptive approaches. The need for a better understanding of mare folliculogenesis and conception factors, including maternal recognition of pregnancy, is also reviewed because they hold considerable potential in providing a non-surgical mechanism for sterilisation. In conclusion, the authors contend that non-surgical measures that are single shot and irreversible may provide a sustainable and effective strategy for feral horse control. PMID- 27700984 TI - An electrostatic selection mechanism controls sequential kinase signaling downstream of the T cell receptor. AB - The sequence of events that initiates T cell signaling is dictated by the specificities and order of activation of the tyrosine kinases that signal downstream of the T cell receptor. Using a platform that combines exhaustive point-mutagenesis of peptide substrates, bacterial surface-display, cell sorting, and deep sequencing, we have defined the specificities of the first two kinases in this pathway, Lck and ZAP-70, for the T cell receptor zeta chain and the scaffold proteins LAT and SLP-76. We find that ZAP-70 selects its substrates by utilizing an electrostatic mechanism that excludes substrates with positively charged residues and favors LAT and SLP-76 phosphosites that are surrounded by negatively-charged residues. This mechanism prevents ZAP-70 from phosphorylating its own activation loop, thereby enforcing its strict dependence on Lck for activation. The sequence features in ZAP-70, LAT, and SLP-76 that underlie electrostatic selectivity likely contribute to the specific response of T cells to foreign antigens.

AB - The bio-active compounds of ginger (Zingiber officinale Roscoe), the gingerols, are gaining considerable attention due to their numerous beneficial health effects. In order to elucidate the physiological relevance of the ascribed effects their bioavailability has to be determined taking their metabolization into account. To quantitate in vivo generated [6]-, [8]- and [10]-gingerol glucuronides in human plasma and urine after ginger tea consumption, a simultaneous and direct liquid chromatography-tandem mass spectrometry method based on stable isotope dilution assays was established and validated. The respective references as well as the isotopically labeled substances were synthesized and characterized by mass spectrometry and NMR. Selective isolation of gingerol glucuronides from human plasma and urine by a mixed-phase anion exchange SPE method led to recovery rates between 80.8 and 98.2%. LC-MS/MS analyses in selected reaction monitoring modus enabled a highly sensitive quantitation of gingerol glucuronides with LoQs between 3.9-9.8nmol/L in plasma and 39.3-161.1nmol/L in urine. The method precision in plasma and urine varied in the range+/-15%, whereas the intra-day accuracy in plasma and urine showed values between 78 and 122%. The developed method was then applied to a pilot study in which two volunteers consumed one liter ginger tea. Pharmacokinetic parameters like the maximum concentration (cmax), the time to reach cmax (tmax), area under the curve (AUC), elimination rate constant (kel) and elimination half-life (t1/2) were calculated from the concentration-time curve of each gingerol glucuronide. The obtained results will enable more detailed investigation of gingerol glucuronides as bioactives in their physiologically relevant concentrations. PMID- 27700985 TI - Stochasticity in the miR-9/Hes1 oscillatory network can account for clonal heterogeneity in the timing of differentiation. AB - Recent studies suggest that cells make stochastic choices with respect to differentiation or division. However, the molecular mechanism underlying such stochasticity is unknown. We previously proposed that the timing of vertebrate neuronal differentiation is regulated by molecular oscillations of a transcriptional repressor, HES1, tuned by a post-transcriptional repressor, miR 9. Here, we computationally model the effects of intrinsic noise on the Hes1/miR 9 oscillator as a consequence of low molecular numbers of interacting species, determined experimentally. We report that increased stochasticity spreads the timing of differentiation in a population, such that initially equivalent cells differentiate over a period of time. Surprisingly, inherent stochasticity also increases the robustness of the progenitor state and lessens the impact of unequal, random distribution of molecules at cell division on the temporal spread of differentiation at the population level. This advantageous use of biological noise contrasts with the view that noise needs to be counteracted. PMID- 27700986 TI - Rac1-mediated membrane raft localization of PI3K/p110beta is required for its activation by GPCRs or PTEN loss. AB - We aimed to understand how spatial compartmentalization in the plasma membrane might contribute to the functions of the ubiquitous class IA phosphoinositide 3 kinase (PI3K) isoforms, p110alpha and p110beta. We found that p110beta localizes to membrane rafts in a Rac1-dependent manner. This localization potentiates Akt activation by G-protein-coupled receptors (GPCRs). Thus genetic targeting of a Rac1 binding-deficient allele of p110beta to rafts alleviated the requirement for p110beta-Rac1 association for GPCR signaling, cell growth and migration. In contrast, p110alpha, which does not play a physiological role in GPCR signaling, is found to reside in nonraft regions of the plasma membrane. Raft targeting of p110alpha allowed its EGFR-mediated activation by GPCRs. Notably, p110beta dependent, PTEN null tumor cells critically rely upon raft-associated PI3K activity. Collectively, our findings provide a mechanistic account of how membrane raft localization regulates differential activation of distinct PI3K isoforms and offer insight into why PTEN-deficient cancers depend on p110beta.

AB - In this work, an efficient method for preparative separation of procyanidins from raw cacao bean extract by high-speed counter-current chromatography (HSCCC) was developed. Under the optimized solvent system of n-hexane-ethyl acetate-water (1:50:50, v/v/v) with a combination of head-tail and tail-head elution modes, various procyanidins fractions with different polymerization degrees were successfully separated. UPLC, QTOF-MS and 1H NMR analysis verified that these fractions contained monomer up to pentamer respectively. Dimeric procyanidin B2 (purity>86%) could be isolated by HSCCC in a single run. Other individual procyanidins in these fractions could be further isolated and purified by preparative HPLC. The developed HSCCC together with preparative HPLC techniques appeared to be a useful tool for large preparation of different procyanidins from cacao beans. Furthermore, by antioxidant activity assays, it was proved that both fractions and individual procyanidins possessed greater antioxidant activities compared to standard trolox. The antioxidant activities of procyanidins increase as the increase of their polymerization degree.

AB - Intermittent illumination combined with bio-zeolite fixed-bed process was utilized to improve the efficiency of anaerobic digestion with ammonium-rich substrate. The batch experiments were carried out at NH4+-N concentration of 2211mg/L under intermittent illumination and dark (as control) conditions, respectively. The illuminated bioreactor achieved higher methane production (287mL/g-DOC) and ATP value (0.38MUmol/L) than that under dark condition. Then the bio-zeolite fixed-bed bioreactor (NH4+-N concentration: 3000mg/L) was used to study the additional efficiency on the illuminated ammonium-rich anaerobic digestion process. The result showed that the illuminated fixed-bed bioreactor presented the greatest methane concentration (70%), methane yield (283mL/g-DOC) and quantity of methanogens comparing with no-bed bioreactor. Furthermore, the illuminated fixed-bed bioreactor achieved better performance during 118-day semi continuous fermentation. The combination of the intermittent illumination and bio zeolite fixed-bed strategy contributed to the higher efficiency and stability of the ammonium-rich anaerobic digestion process. PMID- 27700991 TI - Impact of mixing time and energy on the dispersion effectiveness and droplets size of oil. AB - The effects of mixing time and energy on Alaska Northern Slope (ANS) and diluted bitumen Cold Lake Blend (CLB) were investigated using EPA baffled flask test. Dispersion effectiveness and droplet size distribution were measured after 5-120 min. A modeling method to predict the mean droplet size was introduced for the first time to tentatively elucidate the droplet size breakup mechanism. The ANS dispersion effectiveness greatly increased with dispersant and mixing energy. However, little CLB dispersion was noted at small energy input (epsilon = 0.02 Watt/kg). With dispersant, the ANS droplet size distribution reached quasi equilibrium within 10 min, but that of CLB seems to reach quasi-equilibrium after 120 min. Dispersants are assumed ineffective on high viscosity oils because dispersants do not penetrate them. We provide an alternative explanation based on the elongation time of the droplets and its residence in high intensity zones. When mixing energy is small, CLB did not disperse after 120 min, long enough to allow the surfactant penetration. Our findings suggest that dispersants may disperse high viscosity oils at a rougher sea state and a longer time. The latter could determine how far offshore one can intervene for effective responses to a high viscosity oil spill offshore.

AB - Bacteria utilize a diverse set of nucleotide second messengers to regulate cellular responses by binding macromolecular receptors (RNAs and proteins). Recent studies on cyclic di-GMP (c-di-GMP) have shown that this signaling molecule binds multiple receptors to regulate different steps in the same biological process. We propose this property of the same molecule regulating multiple steps in the same process is biologically meaningful and have termed this phenomenon 'sustained sensing'. Here, we discuss the recent findings that support the concept of sustained sensing of c-di-GMP levels and provide additional examples that support the utilization of sustained sensing by other second messengers. Sustained sensing may be widespread in bacteria and provides an additional level of complexity in prokaryotic signal transduction networks. PMID- 27700992 TI - Toxicity assessment of sodium fluoride in Drosophila melanogaster after chronic sub-lethal exposure. AB - Sodium fluoride (NaF), one of the most frequently used fluoride compound is composed of Na+ and F-. Apart from its use in water fluoridation, NaF also acts as a major component for different dental products like toothpastes, gels and mouth rinses etc. The present study was carried out to explore the toxic impact of chronic NaF exposure on a non-target organism, Drosophila melanogaster. The larvae exposed to different concentrations of NaF through food showed a significant increase in HSP70 expression both qualitatively and quantitatively. The altered tail length and tail intensity in Comet assay validate the increased DNA damage in treated larvae. The activity of AChE, oxidative stress marker enzymes, phase I and phase II detoxifying enzymes were found to be significantly inhibited in the treated larvae when compared to control though there was no evidence of dose dependent change in each case. The alterations in the mentioned parameters can be due to increased body Fluoride ion (F-) concentration since the analysis with ion electrode analyzer revealed that F- concentration increased significantly with NaF treatment. Hence, the results suggest that D. melanogaster manifest prominent toxic response when subjected to chronic exposure to sub lethal NaF concentrations. PMID- 27700993 TI - Comparative study for the removal and destruction of pentachlorophenol using activated magnesium treatment systems. AB - Chlorophenols are highly toxic, environmentally-persistent compounds which have been classified as probable human carcinogens by the United States Environmental Protection Agency. Due to the high toxicity of these compounds, it is necessary to treat water and soils with concentrations of chlorophenols above the detection limit set by regulatory agencies. The aim of this work is to demonstrate the capabilities of using ball-milled magnesium for the dechlorination of PCP. Comparison of dechlorination processes were performed in an attempt to determine the most effective system for degradation of PCP to phenol. Three systems with powerful capabilities of treatment were studied: ball-milled zero-valent magnesium (ZVMg), ball-milled zero-valent magnesium carbon (ZVMg/C), and ball milled zero-valent magnesium with palladium (ZVMg/Pd). In addition to measuring PCP disappearance, all byproducts were identified and quantified for each degradation system. The results of these studies indicate that all three of the systems degrade PCP within 30 min. The most rapid and complete PCP dechlorination is achieved using ball-milled Mg/Pd and a matrix consisting of at least 0.02 g Mg0/mL ethanol, and 10 MUL acetic acid/mL ethanol, in which case 20 ng/MUL of PCP was dechlorinated to chlorophenols in approximately 15 min with complete dechlorination achieved in six days. Carbon mass balances of 90.16% for Mg, 94.76% (Mg/C) and 97.05% (Mg/Pd) verify dechlorination was responsible for declining concentrations of PCP. The reactions of PCP degradation and phenol formation were found to follow pseudo-first order kinetics for all systems. Further work will consist of optimization and development of field-scale applications. PMID- 27700994 TI - Efficient destruction of hexachlorobenzene by calcium carbide through mechanochemical reaction in a planetary ball mill. AB - Mechanochemical destruction (MCD) is a good alternative to traditional incineration for the destruction of persistent organic pollutants (POPs), like hexachlorobenzene (HCB), and the key is to find an efficient co-milling reagent. Toward this aim, HCB was milled with various reagents in a planetary ball mill at room temperature, and CaC2 was found to be the best one. HCB can be destroyed completely within 20 min at a mass ratio of CaC2/HCB = 0.9 and a rotation speed of 300 rpm. The ground samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. The results show that the destruction products are nonhazardous CaCl2 and carbon material with both crystalline and amorphous structures. On these bases, possible reaction pathways were proposed. Considering its excellent efficiency and safety, CaC2 may be the most feasible co-milling regent for MCD treatment of HCB. Further, the results are instructive for the destruction of other POPs. PMID- 27700995 TI - Adsorption of organophosphorus pesticides in tropical soils: The case of karst landscape of northwestern Yucatan. AB - This article discusses the adsorption of four organophosphorus pesticides diazinon, dimethoate, methyl parathion, and sulfotep-in soil samples from four sites-Komchen, Xcanatun, Chablekal and Mococha- in the northwest of Yucatan, Mexico. These pesticides have been detected in groundwater at concentrations greater than 5 (MUg/L) during recent monitoring campaigns in the study area. In this region, groundwater contamination is exacerbated by its karst aquifer, which is susceptible to contamination and is considered very vulnerable. The experimental work was carried out using the batch equilibrium technique. Pesticide analyses by solid-phase extraction and gas chromatography were performed. The equilibrium adsorption data were analyzed by Henry, Langmuir and Freundlich models. The results indicate that the Freundlich model provides the best correlation of the experimental data. Freundlich adsorption coefficients Kf were in the range of 1.62-2.35 for sulfotep, 2.43 to 3.25 for dimethoate, from 5.54 to 9.27 for methyl parathion, and 3.22 to 5.17 for diazinon. Freundlich adsorption coefficients were normalized to the content of organic carbon in the soil to estimate the sorption coefficient of organic carbon (KOC). KOC values were in the range of 9.45-71.80, indicated that four pesticides have low adsorption on the four studied soils, which represents a high risk of contamination to the aquifer. PMID- 27700997 TI - Characterization of pH-fractionated humic acids derived from Chinese weathered coal. AB - To reduce the compositional and structural heterogeneity of humic acids (HAs) and achieve better use of HA resources, in this study, we report a new sequential dissolution method for HAs derived from Chinese weathered coal. This method was used to separate HAs into seven fractions by adjusting the pH (3-10) of the extraction solution. The results showed that the HA fractions derived from Chinese weathered coal were concentrated up to 90.31% in the lower pH solutions (3-7). The compositional and structural characteristics of the HA fractions were determined by elemental analysis; ultraviolet-visible (UV-Vis), Fourier transform infrared (FTIR), and solid-state 13C-nuclear magnetic resonance (NMR) spectroscopies; and other techniques. The results showed significant differences among the HA fractions. The concentrations of the total acidic groups and the carboxyl groups decreased with the increasing pH of the extraction solution. However, the HA fractions derived from extraction solutions with pH 3-4 had relatively lower aromaticity but a higher protonated carbon content. The HA fractions derived from extraction solutions with pH 6-7 had the highest aromaticity and the greatest abundance of COO/N-C=O. This study demonstrated that adjusting the pH of the extraction solution is one way to fractionate HAs from Chinese weathered coal and to obtain HA fractions with compositions and structures that could serve as useful material for study and utilization. PMID- 27700996 TI - Pilot investigation of two-stage biofiltration for removal of natural organic matter in drinking water treatment. AB - A pilot study employing two parallel trains of two-stage biofiltration, i.e., a sand/anthracite (SA) biofilter followed by a biologically-active granular activated carbon (GAC) contactor, was conducted to test the efficiency, feasibility and stability of biofiltration for removing natural organic matter (NOM) after coagulation in a drinking water treatment plant. Results showed the biofiltration process could effectively remove turbidity (<0.1 NTU in all effluents) and NOM (>24% of dissolved organic carbon (DOC), >57% of UV254, and >44% of SUVA254), where the SA biofilters showed a strong capacity for turbidity removal, while the GAC contactors played the dominant role in NOM removal. The vertical profile of water quality in the GAC contactors indicated the middle upper portion was the critical zone for the removal of NOM, where relatively higher adsorption and enhanced biological removal were afforded. Fluorescence excitation-emission matrix (EEM) analysis of NOM showed that the GAC contactors effectively decreased the content of humic-like component, while protein-like component was refractory for the biofiltration process. Nutrients (NH4-N and PO4 P) supplementation applied upstream of one of the two-stage biofiltration trains (called engineered biofiltration) stimulated the growth of microorganisms, and showed a modest effect on promoting the biological removal of small non-aromatic compositions in NOM. Redundancy analysis (RDA) indicated influent UV254 was the most explanatory water quality parameter for GAC contactors' treatment performance, and a high load of UV254 would result in significantly reduced removals of UV254 and SUVA254. PMID- 27700998 TI - Coagulation-flocculation as pre-treatment for micro-scale Fe/Cu/O3 process (CF mFe/Cu/O3) treatment of the coating wastewater from automobile manufacturing. AB - A coagulation-flocculation as pre-treatment combined with mFe/Cu/O3 (CF mFe/Cu/O3) process was developed to degrade the pollutants in automobile coating wastewater (ACW). In coagulation-flocculation (CF) process, high turbidity removal efficiency (97.1%) and low COD removal efficiency (10.5%) were obtained under the optimal conditions using Al2(SO4)3.18H2O and CaO. The effluent of CF process (ECF) was further disposed by mFe/Cu/O3 process, and its key operating parameters were optimized by batch experiments. Optimally, COD removal efficiency of ECF obtained by the mFe/Cu/O3 process (i.e., 87.6% after 30 min treatment) was much higher than those of mFe/Cu alone (8.3%), ozone alone (46.6%), and mFe/Cu/air (6.1%), which confirms the superiority of the mFe/Cu/O3 process. In addition, the analysis results of UV-vis, excitation-emission matrix (EEM) fluorescence spectra and GC/MS further confirm that the phenol pollutants of ECF had been effectively decomposed or transformed after CF-mFe/Cu/O3 process treatment. Meanwhile, B/C ratio of ACW increased from 0.19 to 0.56, which suggests the biodegradability was improved significantly. Finally, the operating cost of CF-mFe/Cu/O3 process was about 1.83 USD t-1 for ACW treatment. Therefore, the combined process is a promising treatment technology for the coating wastewater from automobile manufacturing. PMID- 27701000 TI - Effect of halide ions on the photodegradation of ibuprofen in aqueous environments. AB - Typically contained within ambient surface waters and certain industrial wastewaters, are plentiful halide ions, which possess varying degrees of photosensitivity. The effects of halide ions on the photodegradation of ibuprofen (IBP) were investigated under UV irradiation using a 500 W mercury lamp as a light source. Studies of the mechanism of halide ions were inclusive of both their light shielding effects and quenching experiments. The results indicated that chloride ion has a slight inhibition against IBP photodegradation under neutral condition, and significant inhibition is observed with bromide ions and iodide ions. In addition to the observed increased rate of IBP photodegradation in conjunction with elevated pH in solution, the inhibitory effect of halide ions was different. When the pH value of the IBP solution was 5, chloride ions were seen to facilitate the photodegradation of IBP. Halide ions can inhibit IBP photodegradation by means of a light attenuation effect. All of the halide ions significantly facilitated the generation of 1O2. PMID- 27700999 TI - Chemical composition and direct electrochemical oxidation of table olive processing wastewater using high oxidation power anodes. AB - Table olive processing wastewater (TOW) is a notoriously polluting due to its high organic and phenol content. To reduce them, an electrochemical process has been studied for the treatment of this effluent. Experiments were performed with a cell equipped with lead dioxide (PbO2) or boron-doped diamond (BDD) as anode and platinum as cathode, where Table Olive Wastewater (TOW) were destroyed by hydroxyl radicals formed at the anode surface from water oxidation. The comparative study of both systems shows the performance of the BDD anode compared to PbO2, explained by the large amounts of hydroxyl radicals generated effective at BDD anode and its synthesis characteristics. Using LC/MS analysis, it was possible to determine hydroxytyrosol, as major phenolic compounds, in table olive processing wastewater and its concentration reach 890 mg L-1. A possible reaction mechanism oxidation for hydroxytyrosol was proposed. The kinetics decays for hydroxytyrosol degradation on PbO2 anode follows a pseudo-first order reaction with a rate constant 0.9 h-1 for japp value 20 mA cm-2. PMID- 27701001 TI - A case report of laparoscopic cholecystectomy in situs inversus totalis: Technique and anatomical variation. AB - BACHGROUND: Since the first laparoscopic cholecystectomy report in situs inversus totalis in 1991, the safety of this procedure has still been questionable. A few surgeons were preferred to perform an open cholecystectomy due to technical difficulties as well as various anatomical varieties that can be faced during surgery. CASE PRESENTATION: We report a case report of a 50 years old patient came with epigastric pain that radiated to her left shoulder, intermittent nausea, vomiting and bloating after some meals. She did not associate her symptoms with fatty food. She was a known case of situs inversus totalis and had a previous laparoscopic Nissen fundoplication that we performed 5 years ago. A laparoscopic cholecystectomy was performed by a left-handed surgeon, illustrating challenges, technique, and the advantages of left-handed surgeon over right handed ones. DISCUSSION: After the first discovery of situs inversus totalis by Fabricus in the 1600 the standard procedure for cholelithiasis was open surgery. The introduction of the first laparoscopic cholecystectomy in patients with situs inversus put surgeons in challenge for performing laparoscopic rather than open surgery for patients with situs inversus diagnosed with gallbladder disease. Only 67 cases used laparoscopic cholecystectomy in treating situs inversus patients with cholelithiasis. Although technical difficulties and expected anatomical variation are the main challenges in those patients, the current literature confirms the safety of laparoscopy in such cases. CONCLUSION: Despite having all these difficulties, handling this type of operations can be safe and uneventful especially with experienced surgeon. PMID- 27701003 TI - Aorto-hepatic bypass graft for repair of an inferior pancreatico-duodenal artery aneurysm associated with coeliac axis occlusion: A case report. AB - INTRODUCTION: Inferior pancreatico-duodenal artery (IPDA) aneurysms are very rare and commonly associated with coeliac axis stenosis or occlusion due to atherosclerosis, thrombosis or median arcuate ligament syndrome. We present a case of a surgical repair of an IPDA aneurysm with the use of a supra-coeliac aorto-hepatic bypass with a polytetrafluoroethylene (PTFE) graft, following a failed initial attempt at an endovascular repair. PRESENTATION: A 75 year old female, who was under investigation for night sweats, was referred to our team with an incidental finding of a 19mm fusiform IPDA aneurysm. Initial attempt at endovascular coiling of the aneurysm was unsuccessful. Elective surgical repair involved excision of the aneurysm and to restore arterial inflow to the hepatic artery, a PTFE bypass graft was used from the supra-coeliac aorta to the hepatic artery. The patient was well 2 months following the procedure with a patent graft shown on contrast enhanced computer tomography (ceCT). DISCUSSION: Management options for IPDA aneurysms include radiologically guided endovascular approach or surgical repair. Given the high mortality of greater than 50% with ruptured aneurysms intervention is indicated in all detected cases. CONCLUSION: Surgical excision with bypass grafting from the supra-coeliac aorta, as reported by our team, represents a satisfactory management option in patients where interventional approaches have failed or are not appropriate. PMID- 27701002 TI - A rare clinic entity: Huge trichobezoar. AB - INTRODUCTION: Trichobezoar is a rare clinical entity in which a ball of hair amasses within the alimentary tract. It can either be found as isolated mass in the stomach or may extend into the intestine. Trichobezoars mostly occur in young females with psychiatric disorders such as trichophagia and trichotillomania. CASE REPORT: Authors present a giant trichobezoar in an 18year old female presented with complaints of upper abdominal mass, epigastric area pain, anorexia and weight loss. The patient underwent trans-abdominal ultrasonography (USG), Computed tomography (CT), upper gastrointestinal endoscopy and subsequently laparotomy. USG was inconclusive due to non-specific findings. It revealed a thick echogenic layer with posterior dirty shadowing extending from the left sub diaphragmatic area to the right sub hepatic region obscuring the adjacent structures. Abdominal CT images revealed a huge, well defined, multi-layered, heterogeneous, solid appearing, non-enhancing mass lesion in the gastric lumen extending from the gastric fundus to the pyloric canal. An endoscopic attempt was performed for removal of this intraluminal mass, but due to its large size, and hard nature, the endoscopic removal was unsuccessful. Finally the large trichobezoar was removed with open laparotomy. CONCLUSION: Trichobezoars should be suspected in young females with long standing upper abdominal masses; as the possibility of malignancy is not very common in this age group. While USG is inconclusive, trichobezoar can be accurately diagnosed with CT. In patient with huge trichobezoar, laparotomy can be performed firstly because of big size and location of mass, and psychiatric recommendation should be made to prevent relapse of this entity. PMID- 27701004 TI - Cervical fracture from chronic steroid usage presenting as a stroke: A case report. AB - INTRODUCTION: Misdiagnosis of Brown-Sequard-like presentations can delay treatment; potentially endangering the positive outcomes a patient might otherwise have had. Stroke mimics can be perceived as signaling the end of urgent investigation and care once stroke is ruled out; however, stroke mimics themselves can require prompt care. Herein, we discuss an extremely rare case where stroke was ruled out, resulting in a lapse in care that lead to an exacerbated hemiparesis over the following week. PRESENTATION OF CASE: We present a patient with an occult cervical spine fracture with extension of the neck, caused by reduced bone density from a chronic steroid regimen. Nine days after the initial onset of her neurological symptoms, the patient presented to the ED with the complaint of left sided weakness and right-sided sensory loss. She was determined to have a left- sided Brown Sequard syndrome, which resolved following anterior cervical discectomy and fusion at C4-C6 and a laminectomy from C4-C6. DISCUSSION: This case indicated that patients with dangerously low bone density should be weaned off chronic steroid therapy to prevent the onset of osteoporotic symptoms early in adulthood. Furthermore, this case emphasizes the importance of continued investigation of symptoms if a stroke is ruled out and the need for more diligent monitoring of bone density of chronic steroid users. CONCLUSION: Stroke mimics can require the same urgency in care and diagnosis as strokes themselves. PMID- 27701005 TI - Pulmonary venous aneurysm: Forming a glove balloon-like shape. AB - INTRODUCTION: Pulmonary venous aneurysm (PVA) is a candidate for surgery because of the risk of rupture and continued growth even if the patient does not develop mitral valve disorders. PRESENTATION OF CASE: We report the case of PVA that continued to increase in size throughout a 17-year observational period. DISCUSSION AND CONCLUSION: The location and form of the aneurysm are important to consider when choosing the surgical approach. If the aneurysm forms a "glove balloon-like shape," lobectomy is necessary because end-to-end anastomosis is difficult to perform in such cases. PMID- 27701006 TI - Incorporation of feedback during beat synchronization is an index of neural maturation and reading skills. AB - Speech communication involves integration and coordination of sensory perception and motor production, requiring precise temporal coupling. Beat synchronization, the coordination of movement with a pacing sound, can be used as an index of this sensorimotor timing. We assessed adolescents' synchronization and capacity to correct asynchronies when given online visual feedback. Variability of synchronization while receiving feedback predicted phonological memory and reading sub-skills, as well as maturation of cortical auditory processing; less variable synchronization during the presence of feedback tracked with maturation of cortical processing of sound onsets and resting gamma activity. We suggest the ability to incorporate feedback during synchronization is an index of intentional, multimodal timing-based integration in the maturing adolescent brain. Precision of temporal coding across modalities is important for speech processing and literacy skills that rely on dynamic interactions with sound. Synchronization employing feedback may prove useful as a remedial strategy for individuals who struggle with timing-based language learning impairments. PMID- 27701008 TI - Global production, use, and emission volumes of short-chain chlorinated paraffins - A minimum scenario. AB - Short-chain chlorinated paraffins (SCCPs) show high persistence, bioaccumulation potential, and toxicity (PBT properties). Consequently, restrictions on production and use have been enforced in several countries/regions. The Stockholm Convention on Persistent Organic Pollutants recognized the PBT properties and long-range transport potential of SCCPs in 2015 and is now evaluating a possible global phase-out or restrictions. In this context, it is relevant to know which countries are producing/using SCCPs and in which amounts, and which applications contribute most to their environmental emissions. To provide a first comprehensive overview, we review and integrate all publicly available data on the global production and use of both chlorinated paraffins (CPs) as a whole and specifically SCCPs. Considerable amount of data on production/use of CPs and SCCPs are missing. Based on the available data and reported emission factors, we estimate the past and current worldwide SCCP emissions from individual applications. Using the available data as a minimum scenario, we conclude: (i) SCCP production and use is increasing, with the current worldwide production volume being 165,000t/year at least, whereas the global production of total CPs exceeds 1milliont/year. (ii) The worldwide release of SCCPs from their production and use to air, surface water, and soil between 1935 and 2012 has been in the range of 1690-41,400t, 1660-105,000t, and 9460-81,000t, respectively. (iii) The SCCP manufacture and use in PVC, the use in metal working applications and sealants/adhesives, and the use in plastics and rubber contribute most to the emissions to air, surface water, and soil. Thus, the decrease in the environmental emissions of SCCPs requires reduction of SCCP use in (almost) all applications. (iv) Emissions due to the disposal of waste SCCPs cannot be accurately estimated, because relevant information is missing. Instead, we conduct a scenario analysis to provide some insights into it. PMID- 27701007 TI - Time is ripe: maturation of metabolomics in chronobiology. AB - Sleep and circadian rhythms studies have recently benefited from metabolomics analyses, uncovering new connections between chronobiology and metabolism. From untargeted mass spectrometry to quantitative nuclear magnetic resonance spectroscopy, a diversity of analytical approaches has been applied for biomarker discovery in the field. In this review we consider advances in the application of metabolomics technologies which have uncovered significant effects of sleep and circadian cycles on several metabolites, namely phosphatidylcholine species, medium-chain carnitines, and aromatic amino acids. Study design and data processing measures essential for detecting rhythmicity in metabolomics data are also discussed. Future developments in these technologies are anticipated vis-a vis validating early findings, given metabolomics has only recently entered the ring with other systems biology assessments in chronometabolism studies. PMID- 27701009 TI - Cannabis and its effects on driving skills. AB - Traffic policies show growing concerns about driving under the influence of cannabis, since cannabinoids are one of the most frequently encountered psychoactive substances in the blood of drivers who are drug-impaired and/or involved in accidents, and in the context of a legalization of medical marijuana and of recreational use. The neurobiological mechanisms underlying the effects of cannabis on safe driving remain poorly understood. In order to better understand its acute and long-term effects on psychomotor functions involved in the short term ability and long-term fitness to drive, experimental research has been conducted based on laboratory, simulator or on-road studies, as well as on structural and functional brain imaging. Results presented in this review show a cannabis-induced impairment of actual driving performance by increasing lane weaving and mean distance headway to the preceding vehicle. Acute and long-term dose-dependent impairments of specific cognitive functions and psychomotor abilities were also noted, extending beyond a few weeks after the cessation of use. Some discrepancies found between these studies could be explained by factors such as history of cannabis use, routes of administration, dose ranges, or study designs (e.g. treatment blinding). Moreover, use of both alcohol and cannabis has been shown to lead to greater odds of making an error than use of either alcohol or cannabis alone. Although the correlation between blood or oral fluid concentrations and psychoactive effects of THC needs a better understanding, blood sampling has been shown to be the most effective way to evaluate the level of impairment of drivers under the influence of cannabis. The blood tests have also shown to be useful to highlight a chronic use of cannabis that suggests an addiction and therefore a long-term unfitness to drive. Besides blood, hair and repeated urine analyses are useful to confirm abstinence. PMID- 27701010 TI - The development of the grasp height effect as a measure of efficient action planning in children. AB - One effect that illustrates how people adjust aspects of their grasping according to situational constraints is the grasp height effect; when reaching for objects positioned at different heights, adults' grasp height (vertical position of the hand on the object) tends to correlate negatively with object height. This indicates that grasp positions are planned so that they facilitate later placements of the object. The current study investigated the development of the grasp height effect with 3-year-old children, 5-year-old children, and adults. This paradigm allows for studying efficient action planning in the context of a simple task with relatively low motor requirements. Other tasks used so far for studying this issue involved relatively complex adjustments of hand position that younger children might have found difficult to perform. Usually, preschoolers' performance on these tasks was relatively low. We expected that, due to the lower motor requirements of the grasp height paradigm, clearer evidence of efficient planning might be found in preschool children. A second focus of this study was to explore children's behavior in different movement phases of the grasping task. Whereas the task of placing an object at different heights involves planning, putting the object back to its original position seems to depend on recall. The results indicate a significant grasp height effect in all age groups but also significant development across the studied age range. Regarding the second movement phase, when participants were required to put the objects back on the original home shelf, 3- and 5-year-olds did not seem to act based on recall in this context. PMID- 27701011 TI - Further evidence for a role of the ADRB2 gene in risk for posttraumatic stress disorder. AB - The aim of the present study was to attempt to replicate the recently reported finding associating rs2400707 of the Adrenoceptor Beta 2, Surface (ADRB2) gene and childhood trauma on PTSD symptoms. Participants included a predominantly veteran cohort of non-Hispanic blacks (NHB; n = 949) and a pre-dominantly veteran cohort of non-Hispanic whites (NHW; n = 759). No main effects were observed for rs2400707 on PTSD diagnosis. Among the NHB participants, we observed an interaction between rs2400707 and history of childhood trauma, whereby with each additional A allele, the odds of having PTSD increased by 1.31, but only among those who had experienced childhood trauma (p = 0.038). The interaction with rs2400707 and childhood trauma was not observed among the NHW study participants (p = 0.892). Taken together, the findings from the present research provide further evidence that the adrenergic system may be an important modulator of PTSD risk; however, additional work is still needed to clarify the exact nature of the relationship between PTSD and rs2400707 of the ADRB2 gene. PMID- 27701013 TI - Peer-based health interventions for people with serious mental illness: A systematic literature review. AB - Health interventions delivered by peer specialists or co-facilitated by peer specialists and health professionals can help improve the physical health of people with serious mental illness (SMI). Yet, the quality of the studies examining these health interventions and their impact on health outcomes remains unclear. To address this gap, we conducted a systematic literature review of peer based health interventions for people with SMI. We rated the methodological quality of studies, summarized intervention strategies and health outcomes, and evaluated the inclusion of racial and ethnic minorities in these studies. We used the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines to conduct our systematic literature review. Electronic bibliographic databases and manual searches were used to locate articles that were published in English in peer-reviewed journals between 1990 and 2015, described peer-based health interventions for people with SMI, and evaluated the impact of the interventions on physical health outcomes. Two independent reviewers used a standardized instrument to rate studies' methodological quality, abstracted study characteristics, and evaluated the effects of the interventions on different health outcomes. Eighteen articles were reviewed. Findings indicated that the strength of the evidence generated from these studies is limited due to several methodological limitations. Mixed and limited intervention effects were reported for most health outcomes. The most promising interventions were self-management and peer-navigator interventions. Efforts to strengthen the evidence of peer based interventions require a research agenda that focuses on establishing the efficacy and effectiveness of these interventions across different populations and settings. PMID- 27701012 TI - A systematic review and secondary data analysis of the interactions between the serotonin transporter 5-HTTLPR polymorphism and environmental and psychological factors in eating disorders. AB - OBJECTIVES: To summarize and synthesize the growing gene x environment (GxE) research investigating the promoter region of the serotonin transporter gene (5 HTTLPR) in the eating disorders (ED) field, and overcome the common limitation of low sample size, by undertaking a systematic review followed by a secondary data meta-analysis of studies identified by the review. METHOD: A systematic review of articles using PsycINFO, PubMed, and EMBASE was undertaken to identify studies investigating the interaction between 5-HTTLPR and an environmental or psychological factor, with an ED-related outcome variable. Seven studies were identified by the systematic review, with complete data sets of five community (n = 1750, 64.5% female) and two clinical (n = 426, 100% female) samples combined to perform four secondary-data analyses: 5-HTTLPR x Traumatic Life Events to predict ED status (n = 909), 5-HTTLPR x Sexual and Physical Abuse to predict bulimic symptoms (n = 1097), 5-HTTLPR x Depression to predict bulimic symptoms (n = 1256), and 5-HTTLPR x Impulsiveness to predict disordered eating (n = 1149). RESULTS: Under a multiplicative model, the low function (s) allele of 5-HTTLPR interacted with traumatic life events and experiencing both sexual and physical abuse (but not only one) to predict increased likelihood of an ED and bulimic symptoms, respectively. However, under an additive model there was also an interaction between sexual and physical abuse considered independently and 5 HTTLPR, and no interaction with traumatic life events. No other GxE interactions were significant. CONCLUSION: Early promising results should be followed-up with continued cross-institutional collaboration in order to achieve the large sample sizes necessary for genetic research.

AB - In 2013 we unveiled the cryo-electron microscopy (CryoEM) method of MicroED, or three-dimensional (3D) electron diffraction of microscopic crystals. Here tiny 3D crystals of biological material are used in an electron microscope for diffraction data collection under cryogenic conditions. The data is indexed, integrated, merged and scaled using standard X-ray crystallography software to determine structures at atomic resolution. In this review we provide an overview of the MicroED method and compare it with other CryoEM methods.

AB - A series of TiO2-N/SnO2X heterostructure photocatalysts were synthesized by a hydrolysis-deposition method. The structure, existing states of N and SnO2 heterostructure at the interface of TiO2-N/SnO2X were studied by EADX, XRD, Raman, FT-IR, XPS, and HRTEM. The band structure is investigated by both theoretical calculation and experiment characterization. It was found that the introduction of NOx surface species and SnO2 nanoparticles would enhance the absorption in visible region, increase reactive oxidative species and separate photogenerated electrons and holes efficiently. Therefore, the photocatalytic activity is improved significantly for TiO2-N/SnO2X, compared with TiO2-N and TiO2 under visible and UV light irradiation. This work may offer a new strategy to fabricate new photocatalyst with high photocatalytic performance.

AB - Insulin loading into the HII mesophases was examined as a function of its concentration, with addition of glycerol as a cosolvent and with addition of phosphatidylcholine (PC) as a structural stabilizer. The structural properties, the molecular interactions, the viscoelastic properties, and the dynamic behavior were investigated by SAXS, ATR-FTIR, and rheological measurements. Insulin release was then monitored and analyzed. Insulin incorporation into the HII systems shrank the cylinders as it competed with the lipids in water-bonding. Insulin interrupted the interface while increasing taumax and creating a more solid-like response. Upon addition of PC, cooperative flow behavior was detected, which is probably the reason for increase in insulin cumulative release from 28% to 52% after 300 min. In the presence of glycerol, the system was less cooperative but insulin was more compactly folded, resulting in a slight improvement in insulin release (up to 6%). Addition of both PC and glycerol caused the maximum release (55%). The addition of additives into the HII system demonstrates how structural modifications can improve insulin release, and influence future design of encapsulated drug delivery systems.

AB - Bio-based catalyst support materials with high thermal and structural stability are desired for catalysts systems requiring harsh conditions. In this study, a thermally stable palladium catalyst (up to 440 degrees C) was designed from sporopollenin, which occurs naturally in the outer exine layer of pollens and is widely acknowledged as chemically very stable and inert biological material. Catalyst design procedure included (1) extraction of sporopollenin microcapsules from Betula pendula pollens (~25MUm), (2) amino-functionalisation of the microcapsules, (3) Schiff base modification and (4) preparation of Pd(II) catalyst. The catalytic activity of the sporopollenin microcapsule supported palladium catalyst was tested in catalysis of biaryls by following a fast, simple and green microwave-assisted method. We recorded outstanding turnover number (TON: 40,000) and frequency (TOF: 400,000) for the catalyst in Suzuki coupling reactions. The catalyst proved to be reusable at least in eight cycles. The catalyst can be suggested for different catalyst systems due to its thermal and structural durability, reusability, inertness to air and its eco-friendly nature.

AB - DIX domain containing 1 (DIXDC1), is a human homolog of Ccd1, a DIX domain containing protein in zebrafish. The present study was undertaken to determine the expression and biologic function of DIXDC1 in Non-Hodgkin's lymphoma (NHL). Clinically, we detected that the expression of DIXDC1 was significantly lower in the indolent lymphomas compared with the progressive lymphomas by immunohistochemistry analysis. Functionally, we found that DIXDC1 could promote cell proliferation via modulating cell cycle progression and PI3K/AKT signaling pathway in NHLs. Moreover, we confirmed that DIXDC1 was involved in the process of lymphoma cell adhesion mediated drug resistance (CAM-DR). Adhesion to fibronectin (FN) or HS-5 up-regulated DIXDC1 expression, and up-regulation of DIXDC1 resulted in an increased expression of p-AKT, which promoted CAM-DR. Our finding supports the role of DIXDC1 in cell proliferation, cell cycle and CAM-DR in NHLs. We propose that inhibition of DIXDC1 expression may be a novel therapeutic approach for NHLs patients, and it may be a target for drug resistance. PMID- 27701019 TI - Comparing the validity of the payment card and structured haggling willingness to pay methods: The case of a diabetes prevention program in rural Kenya. AB - BACKGROUND: The objective of this study was to compare the theoretical validity of two willingness-to-pay (WTP) methods, the commonly used payment card (PC) and the recently developed structured haggling (SH), for estimating the potential benefits of a diabetes prevention program in rural Kenya. METHODS: A convenience sample of adult residents from a rural county in Kenya (Kiambu), with no history of diabetes, was randomly assigned to one of two WTP methods, PC or SH, using structured face-to-face interviews from December 2011 to February 2012. RESULTS: A total of 376 respondents completed the interviews using PC (n = 185) or SH (n = 191). More than 95% of respondents were willing to pay something for program access. The study showed that both methods were feasible in rural Kenya. SH resulted in a higher annual mean WTP than PC, Ksh504.05 (US$7.25) versus Ksh619.95 (US$5.90), respectively (p < 0.01). Based on theory, it was hypothesized that certain predisposing factors would result in greater WTP. Greater socio-economic status (measured using income proxies) resulted in greater unconditional WTP for both the PC and SH groups (t-tests and bivariate correlations) and conditional WTP (GLM models). GLM for PC showed being male, employed and having distant relatives with diabetes were significant predictors for WTP, while for SH being educated, employed and owning a vehicle were significant predictors. CONCLUSION: Both PC and SH showed theoretical validity in rural Kenya. However, the use of SH over PC in rural Kenya may be the better choice given that SH more closely mirrors marketplace transactions in this setting and the use of SH resulted in more significant variables in the GLM models. PMID- 27701020 TI - How much are built environments changing, and where?: Patterns of change by neighborhood sociodemographic characteristics across seven U.S. metropolitan areas. AB - Investments in neighborhood built environments could increase physical activity and overall health. Disproportionate distribution of these changes in advantaged neighborhoods could inflate health disparities. Little information exists on where changes are occurring. This paper aims to 1) identify changes in the built environment in neighborhoods and 2) investigate associations between high levels of change and sociodemographic characteristics. Using Geographic Information Systems, neighborhood land-use, local destinations (for walking, social engagement, and physical activity), and sociodemographics were characterized in 2000 and 2010 for seven U.S. cities. Linear and change on change models estimated associations of built environment changes with baseline (2000) and change (2010 2000) in sociodemographics. Spatial patterns were assessed using Global Moran's I to measure overall clustering of change and Local Moran's I to identify statistically significant clusters of high increases surrounded by high increases (HH). Sociodemographic characteristics were compared between HH cluster and other tracts using Analysis of Variance (ANOVA). We observed small land-use changes but increases in the destination types. Greater increases in destinations were associated with higher percentage non-Hispanic whites, percentage households with no vehicle, and median household income. Associations were present for both baseline sociodemographics and changes over time. Greater increases in destinations were associated with lower baseline percentage over 65 but higher increases in percentage over 65 between 2000 and 2010. Global Moran's indicated changes were spatially clustered. HH cluster tracts started with a higher percentage non-Hispanic whites and higher percentage of households without vehicles. Between 2000 and 2010, HH cluster tracts experienced increases in percent non-Hispanic white, greater increases in median household income, and larger decreases in percent of households without a vehicle. Changes in the built environment are occurring in neighborhoods across a diverse set of U.S. metropolitan areas, but are patterned such that they may lead to increased health disparities over time. PMID- 27701022 TI - DNA vaccine encoding molecular chaperone GroEL of Edwardsiella tarda confers protective efficacy against edwardsiellosis. AB - In the present study, molecular chaperone GroEL of Edwardsiella tarda was found both react with flounder (Paralichthys olivaceus) anti-recombinant GroEL (rGroEL) and anti-E. tarda antibodies, and it was both detected in the outer membrane and the secretome. To evaluate the vaccine potential of GroEL, pCI-neo-GFP-GroEL (pCG GroEL) was prepared and used to vaccinate healthy flounder, and immune protective effects were investigated. The results showed that pCG-GroEL produced an RPS of 60% following E. tarda challenge at week 5 after immunization. Moreover, GroEL transcripts and GFP-tagged GroEL could be detected in vaccinated flounder after immunization with pCG-GroEL, and the GFP-tagged GroEL could be also detected in HINAE cells after transfection with pCG-GroEL. Meanwhile, the immune response of flounder induced by pCG-GroEL was investigated, and the results showed that: (1) the levels of specific serum antibodies against E. tarda induced by pCG-GroEL were significantly higher than other groups at 3-5 week post vaccination; (2) pCG GroEL could induce the proliferation of sIg+ lymphocytes, and the levels of sIg+ lymphocytes in blood, spleen and pronephros of pCG-GroEL vaccinated fish were significantly increased compared with the PBS vaccinated fish at 3w, 2w and 2w after immunization, respectively; (3) MHCIalpha, MHCIIalpha, CD4-1, CD8alpha, IL 1beta and TNF-alpha were significantly induced by immunization with pCG-GroEL, and the mRNA levels of CD4-1 and CD8alpha rapidly increased in pCG-GroEL vaccinated fish after challenge with E. tarda. Taking together, pCG-GroEL could elicit highly protective effects against E. tarda and induce strong immune response of flounder, suggesting that GroEL was a promising vaccine candidate. PMID- 27701023 TI - Workplace road safety risk management: An investigation into Australian practices. AB - In Australia, more than 30% of the traffic volume can be attributed to work related vehicles. Although work-related driver safety has been given increasing attention in the scientific literature, it is uncertain how well this knowledge has been translated into practice in industry. It is also unclear how current practice in industry can inform scientific knowledge. The aim of the research was to use a benchmarking tool developed by the National Road Safety Partnership Program to assess industry maturity in relation to risk management practices. A total of 83 managers from a range of small, medium and large organisations were recruited through the Victorian Work Authority. Semi-structured interviews aimed at eliciting information on current organisational practices, as well as policy and procedures around work-related driving were conducted and the data mapped onto the benchmarking tool. Overall, the results demonstrated varying levels of maturity of risk management practices across organisations, highlighting the need to build accountability within organisations, improve communication practices, improve journey management, reduce vehicle-related risk, improve driver competency through an effective workplace road safety management program and review organisational incident and infringement management. The findings of the study have important implications for industry and highlight the need to review current risk management practices. PMID- 27701021 TI - Endothelial adhesion molecules and multiple organ failure in patients with severe sepsis. AB - OBJECTIVE: To determine if serum levels of endothelial adhesion molecules were associated with the development of multiple organ failure (MOF) and in-hospital mortality in adult patients with severe sepsis. DESIGN: This study was a secondary data analysis of a prospective cohort study. SETTING: Patients were admitted to two tertiary intensive care units in San Antonio, TX, between 2007 and 2012. PATIENTS: Patients with severe sepsis at the time of intensive care unit (ICU) admission were enrolled. Inclusion criteria were consistent with previously published criteria for severe sepsis or septic shock in adults. Exclusion criteria included immunosuppressive medications or conditions. INTERVENTIONS: None. MEASUREMENTS: Baseline serum levels of the following endothelial cell adhesion molecules were measured within the first 72h of ICU admission: Intracellular Adhesion Molecule 1 (ICAM-1), Vascular Cell Adhesion Molecule-1 (VCAM-1), and Vascular Endothelial Growth Factor (VEGF). The primary and secondary outcomes were development of MOF (?2 organ dysfunction) and in hospital mortality, respectively. MAIN RESULTS: Forty-eight patients were enrolled in this study, of which 29 (60%) developed MOF. Patients that developed MOF had higher levels of VCAM-1 (p=0.01) and ICAM-1 (p=0.01), but not VEGF (p=0.70) compared with patients without MOF (single organ failure only). The area under the curve (AUC) to predict MOF according to VCAM-1, ICAM-1 and VEGF was 0.71, 0.73, and 0.54, respectively. Only increased VCAM-1 levels were associated with in-hospital mortality (p=0.03). These associations were maintained even after adjusting for APACHE and SOFA scores using logistic regression. CONCLUSIONS: High levels of serum ICAM-1 was associated with the development of MOF. High levels of VCAM-1 was associated with both MOF and in-hospital mortality. PMID- 27701024 TI - A Bayesian procedure for evaluating the frequency of calibration factor updates in highway safety manual (HSM) applications. AB - The Highway Safety Manual (HSM) presents statistical models to quantitatively estimate an agency's safety performance. The models were developed using data from only a few U.S. states. To account for the effects of the local attributes and temporal factors on crash occurrence, agencies are required to calibrate the HSM-default models for crash predictions. The manual suggests updating calibration factors every two to three years, or preferably on an annual basis. Given that the calibration process involves substantial time, effort, and resources, a comprehensive analysis of the required calibration factor update frequency is valuable to the agencies. Accordingly, the objective of this study is to evaluate the HSM's recommendation and determine the required frequency of calibration factor updates. A robust Bayesian estimation procedure is used to assess the variation between calibration factors computed annually, biennially, and triennially using data collected from over 2400 miles of segments and over 700 intersections on urban and suburban facilities in Florida. Bayesian model yields a posterior distribution of the model parameters that give credible information to infer whether the difference between calibration factors computed at specified intervals is credibly different from the null value which represents unaltered calibration factors between the comparison years or in other words, zero difference. The concept of the null value is extended to include the range of values that are practically equivalent to zero. Bayesian inference shows that calibration factors based on total crash frequency are required to be updated every two years in cases where the variations between calibration factors are not greater than 0.01. When the variations are between 0.01 and 0.05, calibration factors based on total crash frequency could be updated every three years. PMID- 27701025 TI - The effect of a nurse led telephone supportive care programme on patients' quality of life, received information and health care contacts after oesophageal cancer surgery-A six month RCT-follow-up study. AB - BACKGROUND: Following oesophagectomy, a major surgical procedure, it is known that patients suffer from severely reduced quality of life and have an unmet need for postoperative support. Still, there is a lack of research testing interventions aiming to enhance the patients' life situation after this surgical procedure. AIM: The aim of the study was to evaluate the effect of a nurse led telephone supportive care programme on quality of life (QOL), received information and the number of healthcare contacts compared to conventional care following oesophageal resection for cancer. METHOD: The study was designed as a randomized controlled trial (RCT) aiming to test the effect of a nurse led telephone supportive care program compared to conventional care. Patient assessments were conducted at discharge, 2 weeks, 2, 4 and 6 months after discharge and comprised evaluation of QOL, received information and the number of health care contacts. Statistical testing were conducted with repeated measurements analysis of variance to test if there were differences between the groups during follow-up. RESULT: The results show that the intervention group was significantly more satisfied with received information for items concerning the information they received about things to do to help yourself, written information and for the global information score. The control group scored significantly higher on the item regarding wishing to receive more information and wish to receive less information. No effect of the intervention was shown on QOL or number of health care contacts. CONCLUSION: Proactive nurse-led telephone follow-up has a significant positive impact on the patients' experience of received information. This is likely to have a positive effect on their ability to cope with a life that may include remaining side effects and adverse symptoms for a long time after surgery. PMID- 27701026 TI - Correspondence between adolescent and informant reports of substance use: Findings from the Philadelphia Neurodevelopmental Cohort. AB - Inclusion of collateral informant reports is common in adolescent psychopathology research and clinical assessment, yet few studies have examined agreement on ratings of adolescent substance use or factors that may be associated with reporter agreement. The present study aimed to extend prior work on the correspondence between adolescent and informant reports of adolescent substance use with data from a large (n=5214), diverse, community-based sample of youth aged 11-17 (mean age=14.53, SD=1.98; 52% female). Specifically, we examined: (a) agreement between adolescent and collateral informant reports of adolescent use of alcohol, marijuana, cocaine, inhalants, and stimulants and (b) potential correlates of reporter agreement. Agreement ranged from low (kappa=0.007, p=0.053) for inhalant use to moderate (kappa=0.414, p<0.001) for marijuana use. Disagreements were mainly driven by collateral underestimation of adolescent substance use. Older adolescent age was associated with poorer agreement across all substances (Odds Ratios [ORs]<=0.80, ps<0.05) except inhalants (OR=1.28, p<0.001). Reporter agreement on alcohol and marijuana use was lower for male than female adolescents (ORs<=0.85, ps<0.05). Adolescent psychopathology was associated with poorer agreement on all substances (ORs<=0.62, ps<0.01). For alcohol and marijuana, past year frequency of use was associated with better reporter agreement (ORs>=1.54, ps<0.001). For marijuana, older age at first use was related to poorer agreement (OR=0.81, p=0.01). Our results suggest that collateral reports of adolescent substance use may be ineffective proxies for adolescent self-reports in community samples, particularly for low base rate substances. Findings also highlight important factors to consider when collecting substance use information from multiple informants. PMID- 27701027 TI - Self-reported attentional and motor impulsivity are related to age at first methamphetamine use. AB - INTRODUCTION: Methamphetamine (MA) users report higher levels of impulsivity relative to healthy controls, which may either result from, or precede, their substance use. Further, there is evidence that female MA users may be more impulsive than male MA users prior to MA use. Thus, the goal of the current study was to determine whether different subtraits of self-reported impulsivity are significantly related to age at first MA use, controlling for total years of MA use. METHODS: A community sample of MA users was recruited for this study (N=157; 113 males, 44 females). The Barratt Impulsiveness Scale (BIS-11) was used to assess self-reported impulsivity on three subscales (Attentional, Motor, Non planning). Age at first MA use served as the dependent variable in a series of multiple regression models with BIS-11 subscales, sex, and their interaction as independent variables, controlling for total years of MA use. RESULTS: Attentional and Motor impulsivity were significantly related to age at first MA use when controlling for total years of MA use (Attentional: p=0.008; Motor: p=0.003). CONCLUSIONS: Individuals who reported higher Attentional and Motor impulsivity started using MA at an earlier age, which could suggest that impulsivity levels may be an important marker of vulnerability towards MA use. These findings indicate that prevention efforts may be targeted towards individuals who report high levels of Attentional and Motor impulsivity, as they may be at greatest risk for earlier initiation of MA use. PMID- 27701028 TI - Prediction of intramuscular fat content using CT scanning of packaged lamb cuts and relationships with meat eating quality. AB - Novel, multi-object X-ray computed tomography (CT) methodologies can individually analyse vacuum-packed meat samples scanned in batches of three or more, saving money and time compared to scanning live animals. If intramuscular fat (IMF), as a proxy for meat quality, can be predicted with similar accuracies as in live lambs, this method could be used to grade on quality, or to inform breeding programmes. Lamb loin cuts from commercial carcasses (n=303), varying in fat and conformation grade, were vacuum-packed and CT scanned, then tested for meat quality traits and by a trained taste panel. Tissue density values measured by CT, alongside carcass and loin weights, predicted IMF with moderate accuracy (R2 0.36), but did not accurately predict shear force or sensory traits. Juiciness and flavour increased linearly with IMF, whilst texture and overall liking increased to an optimum between 4 and 5% IMF. Samples predicted by CT as having >3% IMF scored significantly higher for sensory traits, than those predicted as <3% IMF. PMID- 27701030 TI - The relationship between educational stress, stress coping, self-esteem, social support, and health status among nursing students in Turkey: A structural equation modeling approach. AB - BACKGROUND: Nursing education can be a stressful experience. To fully benefit from this experience and develop a positive professional identity, it is essential for nursing students to effectively cope with education-related stress. PURPOSE: The aim of the study was to investigate the relationships between nursing students' education-related stress and stress coping, self-esteem, social support, and health status. METHOD: This study utilized a cross-sectional, descriptive, and correlational design. The sample consisted 517 nursing students from a bachelor program in Turkey during the 2014-2015 academic year. Participants provided data on sociodemographic characteristics as well as completing the following instruments: Nursing Education Stress Scale, Coping Behavior Inventory for Nursing Students, Multidimensional Scale of Perceived Social Support, Rosenberg Self-Esteem Scale, and General Health Questionnaire. Relationships were examined using multivariate structural equation modeling. RESULTS: Results indicated that nursing students' stress coping levels were affected by self-esteem and social support. Additionally, this interaction appears to affect general health status. Although the direct effect of stress on coping was non-significant, its overall effect was significant within the model. CONCLUSION: It is necessary to conduct further intervention studies examining the role of self-esteem and social support in facilitating nursing students' stress related coping during their education. PMID- 27701029 TI - Epilepsy, amyloid-beta, and D1 dopamine receptors: a possible pathogenetic link? AB - Experimental and clinical observations indicate that amyloid-beta1-42 (Abeta1-42) peptide not only represents a major actor in neurodegenerative mechanisms but also induce hyperexcitation in individual neurons and neural circuits. In this abnormal excitability, possibly leading to seizures, the D1 dopamine (DA) receptors may play a role. Cerebrospinal fluid levels of Abeta1-42 were measured in patients with late-onset epilepsy of unknown etiology. Moreover, the effect of amyloid peptide on the hippocampal epileptic threshold and synaptic plasticity and its link to D1 receptor function were tested in experimental mouse model of cerebral amyloidosis and in acute model of Abeta1-42-induced neurotoxicity. Among 272 evaluated epileptic patients, aged >55 years, 35 suffered from late-onset epilepsy of unknown etiology. In these subjects, cerebrospinal fluid Abeta1-42 levels were measured. The effects of Abeta1-42, amyloid oligomers, and D1 receptor modulation on epileptic threshold were analyzed by electrophysiological recordings in the dentate gyrus of mice hippocampal slices. We found that Abeta1 42 levels were significantly decreased in cerebrospinal fluid of patients with late-onset epilepsy of unknown etiology with respect to controls suggesting the cerebral deposition of this peptide in these patients. Abeta1-42 enhanced epileptic activity in mice through a mechanism involving increased surface expression of D1 receptor, and this effect was mimicked by D1 receptor stimulation and blocked by SCH 23390, a D1 receptor antagonist. Abeta1-42 may contribute to the pathophysiology of late-onset epilepsy of unknown origin. Our preclinical findings indicate that the D1 receptor is involved in mediating the epileptic effects of Abeta1-42. This novel link between Abeta1-42 and D1 receptor signaling might represent a potential therapeutic target. PMID- 27701031 TI - Novel selective TOCSY method enables NMR spectral elucidation of metabolomic mixtures. AB - Complex mixture analysis is routinely encountered in NMR-based investigations. With the aim of component identification, spectral complexity may be addressed chromatographically or spectroscopically, the latter being favored to reduce sample handling requirements. An attractive experiment is selective total correlation spectroscopy (sel-TOCSY), which is capable of providing tremendous spectral simplification and thereby enhancing assignment capability. Unfortunately, isolating a well resolved resonance is increasingly difficult as the complexity of the mixture increases and the assumption of single spin system excitation is no longer robust. We present TOCSY optimized mixture elucidation (TOOMIXED), a technique capable of performing spectral assignment particularly in the case where the assumption of single spin system excitation is relaxed. Key to the technique is the collection of a series of 1D sel-TOCSY experiments as a function of the isotropic mixing time (taum), resulting in a series of resonance intensities indicative of the underlying molecular structure. By comparing these taum-dependent intensity patterns with a library of pre-determined component spectra, one is able to regain assignment capability. After consideration of the technique's robustness, we tested TOOMIXED firstly on a model mixture. As a benchmark we were able to assign a molecule with high confidence in the case of selectively exciting an isolated resonance. Assignment confidence was not compromised when performing TOOMIXED on a resonance known to contain multiple overlapping signals, and in the worst case the method suggested a follow-up sel TOCSY experiment to confirm an ambiguous assignment. TOOMIXED was then demonstrated on two realistic samples (whisky and urine), where under our conditions an approximate limit of detection of 0.6mM was determined. Taking into account literature reports for the sel-TOCSY limit of detection, the technique should reach on the order of 10MUM sensitivity. We anticipate this technique will be highly attractive to various analytical fields facing mixture analysis, including metabolomics, foodstuff analysis, pharmaceutical analysis, and forensics. PMID- 27701032 TI - Four pulse recoupling. AB - The paper describes a family of novel recoupling pulse sequences in magic angle spinning (MAS) solid state NMR, called four pulse recoupling. These pulse sequences can be employed for both homonuclear and heteronuclear recoupling experiments and are robust to dispersion in chemical shifts and rf-inhomogeneity. The homonuclear pulse sequence consists of a building block pi20 degrees 3pi2phi degrees pi2180 degrees +phi degrees 3pi2180 degrees where phi=pinphi degrees =180 degrees n, and n is number of blocks in a two rotor period. The heteronuclear recoupling pulse sequence consists of a building block [Formula: see text] and [Formula: see text] on channel I and S, where phi1=3pi2n,phi2=pi2n and n is number of blocks in a two rotor period. The recoupling pulse sequences mix the y magnetization. We show that four pulse recoupling is more broadband compared to three pulse recoupling [1]. Experimental quantification of this method is shown for 13Calpha-13CO, homonuclear recoupling in a sample of Glycine and 15N-13Calpha, heteronuclear recoupling in Alanine. Application of this method is demonstrated on a sample of tripeptide N-formyl-[U-13C,15N]-Met-Leu-Phe-OH (MLF). PMID- 27701033 TI - Norovirus infections in a tertiary care centre - individual cases do not necessarily lead to an outbreak. AB - BACKGROUND: Norovirus is responsible for the majority of gastroenteritis outbreaks within healthcare settings. Routes of spread include foodborne-, waterborne- and especially person-to-person transmissions. OBJECTIVE: We investigated the overall attack rate of norovirus, within and outside outbreak situations, transmitted via patient-to-patient contact in a tertiary care centre from January 2012 to March 2015. STUDY DESIGN: We monitored exposed asymptomatic patients next to infectious patients for the development of symptoms of acute gastroenteritis following exposure. RESULTS: We detected 102 patients with contact to 94 infectious patients. Of these only 11 patients developed typical norovirus symptoms after exposure while 91 patients remained asymptomatic. Total secondary attack rate was only 10.8%. CONCLUSIONS: Patient-to-patient transmission of norovirus is potentially overestimated within clinical settings. Future prevention strategies should consider personal risk factors of exposed patients. PMID- 27701034 TI - Asymmetry in gait pattern following tibial shaft fractures - a prospective one year follow-up study of 49 patients. AB - INTRODUCTION: Despite the high number of studies evaluating the outcomes following tibial shaft fractures, the literature lacks studies including objective assessment of patients' recovery regarding gait pattern. The purpose of the present study was to evaluate whether gait patterns at 6 and 12 months post operatively following intramedullary nailing of a tibial shaft fracture are different compared with a healthy reference population. PATIENTS AND METHODS: The study design was a prospective cohort study. The primary outcome measurement was the gait patterns at 6 and 12 months post-operatively measured with a 6-metre long pressure-sensitive mat. The mat registers footprints and present gait speed, cadence as well as temporal and spatial parameters of the gait cycle. Gait patterns were compared to a healthy reference population. RESULTS: 49 patients were included with a mean age of 43.1 years (18-79 years). Forty-three patients completed the 12-month follow-up (88%). Gait speed and cadence were significantly increased between the 6- and 12-month follow-up (P<0.001). At 6-month follow-up, patients showed considerable asymmetry in the injured leg compared with the non injured leg: single-support time 12.8% shorter, swing-time 12.8% longer, step length 11.9% shorter, and rotation of the foot increased by 32.3%. At the 12 month follow-up, gait asymmetry become almost normalized compared to a healthy reference group. CONCLUSION: In patients treated by intramedullary nailing following a tibial shaft fracture, gait asymmetry accompanied with slower speed and cadence are common during the first 6 months and become normalized compared with a healthy reference population between 6 and 12 months post-operatively. PMID- 27701035 TI - A test of fixed and moving reference point control in posture. AB - This study investigated two contrasting assumptions of the regulation of posture: namely, fixed and moving reference point control. These assumptions were tested in terms of time-dependent structure and data distribution properties when stability is manipulated. Fifteen male participants performed a tightrope simulated balance task that is, maintaining a tandem stance while holding a pole. Pole length (and mass) and the standing support surface (fixed surface/balance board) were manipulated so as to mechanically change the balance stability. The mean and standard deviation (SD) of COP length were reduced with pole length increment but only in the balance board surface condition. Also, the SampEn was lower with greater pole length for the balance board but not the fixed surface. More than one peak was present in the distribution of COP in the majority of trials. Collectively, the findings provide evidence for a moving reference point in the maintenance of postural stability for quiet standing.

AB - The present study investigated the relationship between objective measurements of the available (CoFA), the utilized (CoFU) coefficient of friction and subjective perception of grip or slipperiness. It was hypothesized that significant correlations exist between the perception of grip or slip and the CoF during sports movement and that a minimum CoF was needed to ensure an optimal grip/slipperiness perception. Eighteen healthy active females performed forward and backward cutting tasks onto a forceplate. Six shoes and two floors were used to induce different grip conditions. Subjective ratings and CoFU were assessed for each shoe-floor combination, and mechanical CoFA was also measured in a specific test bed. Significant relationships (p<0.001) were found between grip, slipperiness ratings or CoFA with the CoFU (r=0.98, r=-0.97, r=0.88, respectively). Individual sensory thresholds of the minimum required CoFU were also determined using probit models between the CoFU and the grip acceptability. The mean threshold defined in the present study was 0.70+/-0.11. This meant that below this threshold, the grip perception was not acceptable, whereas above this threshold, the grip was felt good enough to perform the task. In conclusion, strong relationships between subjective perceptions and objective measurements of friction were found in sports-like movements. Moreover, a minimum friction requirement was defined for indoor dry shoe-floor conditions. The present study gives new insights of the shoe-floor interaction and outlines friction requirements for the manufacturers of sports floor or footwear.

AB - A high performance liquid chromatography-diode array detection-tandem mass spectrometry method (HPLC-DAD-MS/MS) was developed for simultaneous determination of phenolic acids and flavonoids in djulis (Chenopodium formosanum Koidz.), a traditional Chinese herb reported to possess vital biological activities. A high yield of phenolic acids and flavonoids was attained by employing 50% ethanol in water as the extraction solvent and shaking in a 60 degrees C water bath for 3h. A total of 8 phenolic acids and 14 flavonoids were separated and identified within 55min by using a Poroshell 120 EC-C18 column with detection at 280nm, flow rate at 0.8mL/min, column temperature at 35 degrees C, and a gradient solvent system of 0.1% formic acid in water and acetonitrile. Two internal standards caffeic acid and kaempferol-3-O-rutinoside were used for quantitation of phenolic acids and flavonoids in djulis respectively. The amounts of phenolic acids ranged from 11.5+/-0.8MUg/g (caffeoyl-putrescine-derivative (2)) to 1855.3+/-16.9MUg/g (hydroxylphenylacetic acid pentoside), while the flavonoids ranged from 19.93+/ 2.29MUg/g (quercetin-3-O-(coumaryl)-rutinoside-pentoside (1)) to 257.3+/ 2.05MUg/g (rutin-O-pentoside (2)). A high recovery (89.68-97.20%) and high reproducibility was obtained for both phenolic acids and flavonoids with the relative standard deviation (RSD) for the latter ranging from 0.09-8.22% (intra day variability) and 0.80-8.48% (inter-day variability). This method may be applied to determination of both phenolic acids and flavonoids in food products and Chinese herbs.

PMID- 27701038 TI - Analysis of fenretinide and its metabolites in human plasma by liquid chromatography-tandem mass spectrometry and its application to clinical pharmacokinetics. AB - A simple and accurate high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the determination of N-(4 hydroxyphenyl)retinamide (fenretinide, 4-HPR) and its metabolites, 4-oxo-N-(4 hydroxyphenyl)retinamide (4-oxo-4-HPR) and N-(4-methoxyphenyl)retinamide (4-MPR), in human plasma. Plasma samples were prepared using protein precipitation with ethanol. Chromatographic separation of the three analytes and N-(4 ethoxyphenyl)retinamide (4-EPR), an internal standard, was achieved on a Zorbax SB-C18 column (3.5MUm, 50*2.1mm) using gradient elution with the mobile phase of 0.1% formic acid in water and acetonitrile (pH* 2.4) at a flow rate of 0.5mL/min. Electrospray ionization (ESI) mass spectrometry was operated in the positive ion mode with multiple reaction monitoring (MRM). The calibration curves obtained were linear over the concentration range of 0.2-50ng/mL with a lower limit of quantification of 0.2ng/mL. The relative standard deviation of intra-day and inter-day precision was below 7.64%, and the accuracy ranged from 94.92 to 105.43%. The extraction recoveries were found to be higher than 90.39% and no matrix effect was observed. The analytes were stable for the durations of the stability studies. The validated method was successfully applied to the analyses of the pharmacokinetic study for patients treated with 4-HPR in a clinical trial. PMID- 27701040 TI - Impact of neonatal risk and temperament on behavioral problems in toddlers born preterm. AB - Children born preterm are at risk for later developmental disorders. The present study examined the predictive effects of neonatal, sociodemographic, and temperament characteristics on behavioral outcomes at toddlerhood, in children born preterm. The sample included 100 toddlers born preterm and with very-low birth-weight, and their mothers. Neonatal characteristics were evaluated using medical records. The mothers were interviewed using the Early Childhood Behavior Questionnaire for temperament assessment, and the Child Behavior Checklist for behavioral assessment. Multiple linear regression analyses were performed. Predictors of 39% of the variability of the total behavioral problems in toddlers born prematurely were: temperament with more Negative Affectivity and less Effortful Control, lower family socioeconomic status, and younger mothers at childbirth. Temperament with more Negative Affectivity and less Effortful Control and lower family socioeconomic status were predictors of 23% of the variability of internalizing behavioral problems. Additionally, 37% of the variability of externalizing behavioral problems was explained by temperament with more Negative Affectivity and less Effortful Control, and younger mothers at childbirth. The neonatal characteristics and stressful events in the neonatal intensive care unit did not predict behavioral problems at toddlerhood. However, temperament was a consistent predictor of behavioral problems in toddlers born preterm. Preventive follow-up programs could assess dispositional traits of temperament to provide early identification of preterm infants at high-risk for behavioral problems. PMID- 27701041 TI - Changes in alcohol use following the transition to motherhood: Findings from the National Epidemiologic Survey on Alcohol and Related Conditions. AB - BACKGROUND: Little is known about the impact of motherhood on alcohol use beyond the acute reductions observed in pregnancy. This study characterizes changes in alcohol use for women who did and did not become mothers over three years. METHODS: Data are from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC). Participants were female respondents aged 18-44 years who did not have children and were not pregnant at wave 1, and who reported having at least one drink in the year prior to wave 1 (n=2118). Women were classified as mothers (n=325) if they reported having a child between waves 1 and 2, and non mothers if they did not (n=1793). At each wave, participants provided information on past-year frequency of alcohol use and heavy episodic drinking, and usual number of alcoholic beverages consumed per occasion. RESULTS: At baseline, women who did and did not become mothers reported similar levels of alcohol use. Women who became mothers reported significant reductions in alcohol use indicators from wave 1 to wave 2 (i.e., 22 fewer drinking days, 15 fewer heavy drinking days, 1 less drink per occasion), whereas women who did not become mothers showed a modest increase in alcohol use frequency (i.e., 7 more drinking days). Motherhood remained significantly associated with reductions in alcohol use after adjusting for sociodemographic variables and baseline alcohol use. CONCLUSIONS: The transition to motherhood is associated with marked reductions in alcohol consumption. Similar reductions were not observed for women who did not become mothers. PMID- 27701043 TI - Single awakening salivary measurements provide reliable estimates of morning cortisol levels in pregnant women. AB - Mood disorders during pregnancy have been associated with adverse effects on maternal as well as fetal health. Since mood, anxiety, and stress disorders are related with elevated cortisol levels, salivary cortisol may be a useful biomarker. Although multiple samples are generally recommended, a single measurement of awakening salivary cortisol could be a simpler and more cost effective method to determine whether women have elevated morning cortisol levels during a specific period of pregnancy. Therefore, the aim of this validation study among 177 women in the PRIDE Study was to examine whether one awakening salivary cortisol measurement will suffice to classify pregnant women as having normal or elevated cortisol levels compared to awakening salivary cortisol measurements on three consecutive working days. We calculated intraclass correlation coefficients (ICC) and Cohen's kappa statistics (kappa) overall as well as in sub-analyses within strata based on maternal age, level of education, net household income, pre-pregnancy BMI, parity, complications during pregnancy, caffeine consumption, gestational week of sampling, and awakening time. The mean cortisol concentrations were 8.98ng/ml (SD 5.32) for day one, 8.62ng/ml (SD 4.55) for day two, and 8.39ng/ml (SD 4.58) for day three. The overall ICC was 0.86 (95% CI 0.82-0.89) while the kappa was 0.75 (95% CI 0.64-0.86). For the ICCs calculated within sub-analyses, a maximum difference of 0.11 was observed between the strata. For the kappa statistics, most strata did not differ more than 0.12, except for pre-pregnancy BMI, severe nausea, and extreme fatigue with differences up to 0.22. In conclusion, one awakening salivary cortisol measurement is as reliable for the classification of pregnant women into normal and elevated morning cortisol levels as salivary cortisol measurements on three consecutive working days. PMID- 27701042 TI - Methadone maintenance therapy and viral suppression among HIV-infected opioid users: The impacts of crack and injection cocaine use. AB - BACKGROUND: Methadone maintenance therapy (MMT) is associated with improved HIV treatment outcomes among people who use drugs (PWUD). The extent to which these benefits are sustained in the context of ongoing cocaine use is unclear. We assessed differential impacts of MMT on HIV viral load (VL) suppression in relation to discrete patterns of cocaine use. METHODS: Data was drawn from ACCESS, a prospective cohort of HIV-positive PWUD in Vancouver, Canada. Generalized linear mixed-effects were used to model the independent effect of MMT on VL suppression across strata of frequency of cocaine injection and crack smoking (>=daily versus =1 study interview between 2005 and 2014. At baseline, 304 (77%) reported participation in MMT, 37 (9%) >=daily cocaine injection, and 158 (40%) >=daily crack smoking. In adjusted analyses, MMT remained independently associated with increased odds of VL suppression in both strata of crack smokers (AOR=3.11, 95% CI: 1.86-5.21 and AOR=1.48, 95%CI: 1.04-2.09, for >=daily and =daily cocaine injectors (AOR=1.37, 95%CI 0.53-3.49). Longer retention on MMT was positively associated with VL suppression in all strata of cocaine injection and crack smoke. CONCLUSIONS: Exposure to MMT was associated with increased odds of VL suppression among HIV- positive opioid users regardless of crack use. However, this beneficial effect of MMT was lost among frequent cocaine injectors with shorter retention on MMT. PMID- 27701044 TI - Corticotropin-releasing hormone induces depression-like changes of sleep electroencephalogram in healthy women. AB - We reported previously that repetitive intravenous injections of corticotropin releasing hormone (CRH) around sleep onset prompt depression-like changes in certain sleep and endocrine activity parameters (e.g. decrease of slow-wave sleep during the second half of the night, blunted growth hormone peak, elevated cortisol concentration during the first half of the night). Furthermore a sexual dimorphism of the sleep-endocrine effects of the hormones growth hormone releasing hormone and ghrelin was observed. In the present placebo-controlled study we investigated the effect of pulsatile administration of 4*50MUg CRH on sleep electroencephalogram (EEG) and nocturnal cortisol and GH concentration in young healthy women. After CRH compared to placebo, intermittent wakefulness increased during the total night and the sleep efficiency index decreased. During the first third of the night, REM sleep and stage 2 sleep increased and sleep stage 3 decreased. Cortisol concentration was elevated throughout the night and during the first and second third of the night. GH secretion remained unchanged. Our data suggest that after CRH some sleep and endocrine activity parameters show also depression-like changes in healthy women. These changes are more distinct in women than in men. PMID- 27701045 TI - The consequences of having a dominant romantic partner on testosterone responses during a social interaction. AB - Testosterone reactivity has been conceptualized as a marker of social submission at low levels and social dominance at high levels. However, hormonal fluctuations in response to romantic partners remain largely unknown. Towards this end, 88 couples (N=176) discussed an emotional video. Prior to the conversation, one member of the dyad (the "agent") was instructed to regulate affective displays in a specific way (express or suppress). The other dyad member (the "partner") was given no special instruction and was unaware of regulation instructions given to the agent. Agents who regulated affective displays were expected to exhibit decreased testosterone from baseline because they were prevented from tuning their emotional responses to their partners. Furthermore, we expected declines in testosterone would be moderated by partners' authoritativeness: People would be particularly submissive to more dominant partners. Predictions were supported for females and partially supported for males. Agents exhibited decreases in testosterone from baseline relative to partners. For females, this main effect was moderated by partners' trait-level authoritativeness: Females interacting with partners higher in authority exhibited larger decreases in testosterone when instructed to restrict their emotion regulation strategies. This research is the first to document testosterone reactivity in existing romantic relationships and underscores the importance of taking into account social and relational contexts when examining hormonal regulation. PMID- 27701047 TI - Spectrophotometric determination of gold(III) in forensic and pharmaceutical samples and results complemented with ICP AES and EDXRF analysis. AB - Spectrophotometric method with three systems were developed here for the determination of gold(III) using o-dianisidine, aniline sulphate and catechol. Gold(III),in the system 1 it oxidizes o-dianisidine, in the system 2 it oxidizes catechol followed by its coupling with o-dianisidine, in the system 3 it oxidizes catechol followed by its coupling with aniline sulphate forming dye products with respective lambdamax 446nm, 540nm, and 505nm. All the three systems were optimized and analytical parameters were calculated. The molar absorptivity values were 9.27*104, 1.97*104 and 1.62*104 respectively for the systems 1, 2 and 3 with the corresponding Sandell sensitivity values (MUgcm-2), 0.0021, 0.0096 and 0.011. The optimized systems were used for the determination of gold present in some forensic jewellery and pharmaceutical samples and the results obtained were compared with the results of all samples determined by Inductively Coupled Plasma - Atomic Emission Spectrometric method and a few of them were also complemented by Energy Dispersive X-Ray Fluorescent spectral analysis. PMID- 27701046 TI - Preoperative prediction of temporal lobe epilepsy surgery outcome. AB - PURPOSE: There is controversy about relative contributions of ictal scalp video EEG recording (vEEG), routine scalp outpatient interictal EEG (rEEG), intracranial EEG (iEEG) and MRI for predicting seizure-free outcomes after temporal lobectomy. We reviewed NIH experience to determine contributions at specific time points as well as long-term predictive value of standard pre surgical investigations. METHODS: Raw data was obtained via retrospective chart review of 151 patients. After exclusions, 118 remained (median 5 years follow up). MRI-proven mesial temporal sclerosis (MTSr) was considered a separate category for analysis. Logistic regression estimated odds ratios at 6-months, 1 year, and 2 years; proportional hazard models estimated long-term comparisons. Subset analysis of the proportional hazard model was performed including only patients with commonly encountered situations in each of the modalities, to maximize statistical inference. RESULTS: Any MRI finding, MRI proven MTS, rEEG, vEEG and iEEG did not predict two-year seizure-free outcome. MTSr was predictive at six months (OR=2.894, p=0. 0466), as were MRI and MTSr at one year (OR=10.4231, p=0. 0144 and OR=3.576, p=0. 0091). Correcting for rEEG and MRI, vEEG failed to predict outcome at 6 months, 1year and 2 years. Proportional hazard analysis including all available follow-up failed to achieve significance for any modality. In the subset analysis of 83 patients with commonly encountered results, vEEG modestly predicted long-term seizure-free outcomes with a proportional hazard ratio of 1.936 (p=0.0304). CONCLUSIONS: In this study, presurgical tools did not provide unambiguous long-term outcome predictions. Multicenter prospective studies are needed to determine optimal presurgical epilepsy evaluation. PMID- 27701048 TI - Cobalt iron oxide nanoparticles induce cytotoxicity and regulate the apoptotic genes through ROS in human liver cells (HepG2). AB - Cobalt iron oxide (CoFe2O4) nanoparticles (CIO NPs) have been one of the most widely explored magnetic NPs because of their excellent chemical stability, mechanical hardness and heat generating potential. However, there is limited information concerning the interaction of CIO NPs with biological systems. In this study, we investigated the reactive oxygen species (ROS) mediated cytotoxicity and apoptotic response of CIO NPs in human liver cells (HepG2). Diameter of crystalline CIO NPs was found to be 23nm with a band gap of 1.97eV. CIO NPs induced cell viability reduction and membrane damage, and degree of induction was dose- and time-dependent. CIO NPs were also found to induce oxidative stress revealed by induction of ROS, depletion of glutathione and lower activity of superoxide dismutase enzyme. Real-time PCR data has shown that mRNA level of tumor suppressor gene p53 and apoptotic genes (bax, CASP3 and CASP9) were higher, while the expression level of anti-apoptotic gene bcl-2 was lower in cells following exposure to CIO NPs. Activity of caspase-3 and caspase-9 enzymes was also higher in CIO NPs exposed cells. Furthermore, co-exposure of N-acetyl cysteine (ROS scavenger) efficiently abrogated the modulation of apoptotic genes along with the prevention of cytotoxicity caused by CIO NPs. Overall, we observed that CIO NPs induced cytotoxicity and apoptosis in HepG2 cells through ROS via p53 pathway. This study suggests that toxicity mechanisms of CIO NPs should be further investigated in animal models. PMID- 27701049 TI - Soluble curcumin amalgamated chitosan microspheres augmented drug delivery and cytotoxicity in colon cancer cells: In vitro and in vivo study. AB - In present investigation, initially curcumin was complexed with 2-HP-beta-CD (curcumin-2-HP-beta-CD-complex) in 1:1 ratio and later amalgamated with chitosan microspheres (curcumin-2-HP-beta-CD-CMs) for selective delivery in colon only through oral route of administration. Various analytical, spectral and in-silico docking techniques revealed that the curcumin was deeply inserted in the 2-HP beta-CD cavity with apparent stability constant of 3.35*10-3M. Furthermore, the mean particle size of 6.8+/-2.6MUm and +39.2+/-4.1mV surface charge of curcumin-2 HP-beta-CD-complex-CMs in addition to encapsulation efficiency of about 79.8+/ 6.3% exhibited that the tailored microspheres were optimum for colon delivery of curcumin. This was also demonstrated in dissolution testing and standard cell proliferation assay in which curcumin-2-HP-beta-CD-complex-CMs exhibited maximum release in simulated colonic fluid (SCF, pH ~7.0-8.0, almond emulsion-beta glucosidase) with improved therapeutic index in HT-29 cells. Consistently, curcumin-2-HP-beta-CD-complex-CMs successively enhanced the colonic bio distribution of curcumin by ~8.36 folds as compared to curcumin suspension in preclinical pharmacokinetic studies. In conclusion, curcumin-2-HP-beta-CD-complex CMs warrant further in vivo tumor regression study to establish its therapeutic efficacy in experimental colon cancer. PMID- 27701050 TI - S-nitroso-N-acetyl penicillamine inhibits spontaneous exit from metaphase-II arrest in rat eggs cultured in vitro. AB - BACKGROUND: Present study was designed to investigate the in vitro effects of nitric oxide (NO) donor such as S-nitroso-N-acetyl penicillamine (SNAP) on spontaneous exit from metaphase-II arrest (SEM-II) in rat eggs cultured in vitro. METHODS: Ovulated eggs were denuded and then exposed to various concentrations (0.0, 0.01, 0.1 and 1.0mM) of SNAP for 3h under in vitro culture conditions. The percentage of SEM-II, specific and total phosphorylated cyclin-dependent kinase-1 (Cdk1), cyclin B1 and anaphase promoting complex/cyclosome (APC/C) levels as well as Cdk1 activity were analyzed. RESULTS: The SEM-II was associated with a decrease of Thr-161 phosphorylated Cdk1 as well as cyclin B1 levels and increase of Thr-14/Tyr-15 phosphorylated Cdk1, APC/C levels and Cdk1 activity in aged eggs cultured in vitro. On the other hand, SNAP treatment prevented a decrease of Thr 161 phosphorylated Cdk1 as well as cyclin B1 levels and increase of Thr-14/Tyr-15 phosphorylated Cdk1, Cdk1 activity that finally prevented SEM-II in a concentration-dependent manner. However, APC/C level was not affected by SNAP during the course of treatment in vitro. CONCLUSIONS: Present data suggest that SNAP prevented SEM-II possibly by increasing high level of NO and thereby maturation promoting factor (MPF) stabilization in rat eggs cultured in vitro. Hence, SNAP could be used to prevent SEM-II that reduces reproductive outcome in several mammalian species. PMID- 27701051 TI - New insight on using aged garlic extract against toxic impacts of titanium dioxide bulk salt triggers inflammatory and fibrotic cascades in male rats. AB - The efficacy of aged garlic extract (AGE) in alleviating the hepatic inflammation and pulmonary fibrotic responses induced by titanium dioxide (TiO2) toxicity was studied. The control group received distilled water. AGE-treated group received AGE (2ml/kgbw). TiO2- intoxicated group received TiO2 (5g/kgbw). AGE combined with TiO2 treated group administered AGE prior TiO2 by six hours at the same previously doses. All treatments were given orally every other day for two months. TiO2- intoxicated rats elicited a significant up-regulation in hepatic TLR-2, TLR-4, NF-KB/p65, CYP1B1 and CYP2B1 with pulmonary MMP-9, TIMP-1, TGF beta1, collagen-1alpha, fibronectin mRNA. Moreover, a significant elevation in serum AST, ALT, LDH, beta-glucuronidase, N-acetyl beta glucosaminidase, hydroxyproline, MMP-9, TIMP-1, fibronectin, TGF-beta1 levels with a significant decrease in total protein that ensued from TiO2 toxicity. The ultra histopathological findings reinforced these results. The co-administration of AGE and TiO2 alleviated these changes. These data support the nutraceutical role of AGE against TiO2 toxicity. PMID- 27701052 TI - The role of microRNAs in colorectal cancer. AB - Colorectal cancer (CRC) is still the third most common cancer in the world. Mechanism of CRC tumorigenesis has been widely studied at the molecular levels, and has been recently entered the area of microRNAs. MicroRNAs are small 19 to 22 nucleotides of RNA that engage in the regulation of cell differentiation, apoptosis, and cell cycle progression. MicroRNAs are similar to small interfering RNA (siRNA), that post-transcriptionally regulate gene expression and control various cellular mechanisms. They are important factors in the carcinogenesis of CRC, one of the most important factors includes microRNA. MicroRNAs have been linked to CRC development, and these molecules have been recently studied as new potential biomarkers in diagnosis and treatment of CRC. Specific microRNA expression patterns help distinguish CRC from other colon related disease, and may be used as a prognostication factor in patients after treatment with different chemotherapy drugs. More over the newest molecular therapy via tumor suppressor micro RNA replacement can be new insight in molecular therapy of CRC. This review summarizes the potential roles of microRNAs as potential biomarkers for CRC diagnosis, and treatment. PMID- 27701054 TI - A novel electrochemical sensor based on Au@PANI composites film modified glassy carbon electrode binding molecular imprinting technique for the determination of melamine. AB - A novel molecularly imprinted electrochemical sensor for the rapid detection of melamine was reported in this paper. Glassy carbon electrode (GCE) was modified by Au and polyaniline composites (Au@PANI) deposited on the surface of GCE and were used to increase the electrode sensitivity and to amplify the sensor signal. Melamine template molecule was further assembled onto Au@PANI by the formation of hydrogen bonds, can implement the selective detection of melamine. This simple but efficient electrochemistry analysis platform presents a low detection limit of 1.39*10-6umolL-1 for detection of melamine, which is remarkably lower than the currently used methods and the previous reports. So, this method may open a new way for the determination of melamine which enables low cost, effective and sensitive determination. This shows the sensor can be potentially utilized for the detection of melamine in food, which allows the sensitive and selective determination of melamine from milk and feed. PMID- 27701055 TI - Reconstituting redox active centers of heme-containing proteins with biomineralized gold toward peroxidase mimics with strong intrinsic catalysis and electrocatalysis for H2O2 detection. AB - A facile and efficient enzymatic reconstitution methodology has been proposed for high-catalysis peroxidase mimics by remolding the redox active centers of heme containing proteins with the in-site biomineralized gold using hemoglobin (Hb) as a model. Catalytic hemin (Hem) was extracted from the active centers of Hb for the gold biomineralization and then reconstituted into apoHb to yield the Hem Au@apoHb nanocomposites showing dramatically improved intrinsic catalysis and electrocatalysis over natural Hb and Hem. The biomineralized gold, on the one hand, would act as "nanowires" to promote the electron transferring of the nanocomposites. On the other hand, it would create a reactivity pathway to pre organize and accumulate more substrates towards the active sites of the peroxidase mimics. Steady-state kinetics studies indicate that Hem-Au@apoHb could present much higher substrate affinity (lower Michaelis constants) and intrinsic catalysis even than some natural peroxidases. Moreover, the application feasibility of the prepared artificial enzymes was demonstrated by colorimetric assays and direct electrocatalysis for H2O2 sensing, showing a detection limitation low as 0.45MUM. Importantly, such a catalysis active-center reconstitution protocol may circumvent the substantial improvement of the intrinsic catalysis and electrocatalysis of diverse heme-containing proteins or enyzmes toward the extensive applications in the chemical, enviromental, and biomedical catalysis fields. PMID- 27701057 TI - Effect of metformin on global gene expression in liver of KKAy mice. AB - BACKGROUND: Metformin is a first-line drug for treating type 2 diabetes mellitus, yet its mechanism remains only partially understood and controversial. In this study we assessed a global gene expression profiling in liver of KKAy mice affected by metformin. This study aimed to identify the novel anti-diabetic mechanisms of metformin. METHODS: After KKAy mice were administered metformin for 5 weeks, the gene changes profile in the livers of KKAy mice were assessed by using the Agilent whole mice genome oligo microarray. RESULTS: Metformin altered the gene expression profiles in liver of KKAy mice. To our best knowledge, some genes have not been reported until now, such as Anxa2, Atf6, and so on. These genes were involved in many pathways, such as peroxisome proliferator activated receptor signaling pathway. CONCLUSIONS: Gene expression changes induced by metformin were in support of the improvement of glucolipid metabolism and insulin resistance in KKAy mice. These findings expanded our knowledge of pharmacological action of metformin, and provided the potential novel insights and interesting information about the molecules involved in the antidiabetic effects of metformin. PMID- 27701056 TI - Nebivolol suppresses asymmetric dimethylarginine and attenuates cyclosporine induced nephrotoxicity and endothelial dysfunction in rats. AB - BACKGROUND: Cyclosporine A (CsA)-induced nephrotoxicity is a challenging problem complicating its chronic use in a large array of autoimmune diseases, as well as in organ transplantation. A considerable body of evidence points to the involvement of nitric oxide (NO) and its endogenous synthesis inhibitor, asymmetric dimethylarginine (ADMA), in CsA-induced renal and cardiovascular adverse effects. In this study, the potential of the third generation beta blocker, nebivolol, to modify the NO/ADMA system is hypothesized to play a role in protection against CsA-induced renal injury and endothelial dysfunction. METHODS: Both in vivo and in vitro studies were carried out on 36 male Wistar rats randomly divided into three groups; normal control, CsA (30mg/kg/day) treated or CsA+nebivolol (30mg/kg and 1mg/kg daily, respectively)-treated groups. After four weeks, blood pressure, lipid profile, renal functions, renal oxidative status, NO, inducible NO synthase and ADMA were assessed. In vitro evaluation of vascular relaxant responses of norepinephrine pre-contracted aortic rings to acetylcholine (ACh) and sodium nitroprusside were evaluated. RESULTS: Concurrent nebivolol treatment significantly attenuated CsA-induced hypertension, impairment of renal functions, oxidative stress and restored the balance in renal NO system with lowering of the elevated ADMA. This was associated with favourable effects on lipid profile. Nebivolol treatment also abrogated the CsA-induced impairment of relaxant responses of aortic rings to ACh. CONCLUSIONS: Nebivolol possesses multifaceted actions that make it advantageous to combat the CsA-induced toxic effects on renal and endothelial functions. PMID- 27701053 TI - MicroRNA-related polymorphisms and non-Hodgkin lymphoma susceptibility in the Multicenter AIDS Cohort Study. AB - BACKGROUND: MicroRNAs, small non-coding RNAs involved in gene regulation, are implicated in lymphomagenesis. We evaluated whether genetic variations in microRNA coding regions, binding sites, or biogenesis genes (collectively referred to as miRNA-SNPs) were associated with risk of AIDS-associated non Hodgkin lymphoma (AIDS-NHL), and serum levels of four lymphoma-related microRNAs. METHODS: Twenty-five miRNA-SNPs were genotyped in 180 AIDS-NHL cases and 529 HIV infected matched controls from the Multicenter AIDS Cohort Study (MACS), and real time polymerase chain reaction was used to quantify serum microRNA levels. Adjusted odds ratios (ORs) estimated using conditional logistic regression evaluated associations between miRNA-SNPs and AIDS-NHL risk. A semi-Bayes shrinkage approach was employed to reduce likelihood of false-positive associations. Adjusted mean ratios (MR) calculated using linear regression assessed associations between miRNA-SNPs and serum microRNA levels. RESULTS: DDX20 rs197412, a non-synonymous miRNA biogenesis gene SNP, was associated with AIDS-NHL risk (OR=1.34 per minor allele; 95% CI: 1.02-1.75), and higher miRNA-222 serum levels nearing statistical significance (MR=1.21 per minor allele; 95% CI: 0.98-1.49). MiRNA-196a2 rs11614913 was associated with decreased central nervous system (CNS) AIDS-NHL (CT vs. CC OR=0.52; 95% CI: 0.27-0.99). The minor allele of HIF1A rs2057482, which creates a miRNA-196a2 binding site, was associated with systemic AIDS-NHL risk (OR=1.73 per minor allele; 95% CI: 1.12-2.67), and decreased CNS AIDS-NHL risk (OR=0.49 per minor allele; 95% CI: 0.25-0.94). CONCLUSIONS: This study suggests that a few miRNA-SNPs are associated with AIDS NHL risk and may modulate miRNA expression. These results support a role for miRNA in AIDS-NHL and may highlight pathways to be targeted for risk stratification or therapeutics. PMID- 27701058 TI - Does valproate therapy in epileptic patients contribute to changing atherosclerosis risk factors? The role of lipids and free fatty acids. AB - BACKGROUND: We aimed to demonstrate the relationship between the valproate (VPA) treatment versus lipid and serum free fatty acids (FFAs) profiles to be the potential atherosclerosis risk factor in epileptic patients. METHODS: Fasting blood samples were taken from 21 adult VPA-treated patients and 21 controls. The profiles of lipids, FFAs, clinical parameters and body mass index (BMI) were evaluated. RESULTS: No significant differences between the study group and controls were found for any of the studied parameters. However, significant differences in the total cholesterol (CHOL), low-density-lipoprotein cholesterol (LDL), triglycerides, the CHOL/HDL (high-density-lipoprotein cholesterol) ratio, and Atherogenic Index of Plasma were observed for overweight patients when compared to those of normal weight. Patients with uncontrolled epilepsy tended to have significantly lower palmitic acid level than seizure-free patients. Oleic acid was found to be positively correlated with VPA concentration for patients with uncontrolled epilepsy, and with the dose corrected VPA concentration for all the patients. The acid was however negatively correlated with stearic acid for both the controls and the patients with uncontrolled epilepsy. PLS method revealed CHOL, LDL, triglycerides and myristic acid to be positively interrelated for the whole group under the study, whereas these parameters were found to be negatively correlated with VPA concentration, and positively with BMI. Furthermore, high sensitivity C-reactive protein was found to be negatively correlated with palmitic acid levels. CONCLUSION: Overweight VPA-treated patients are exposed to higher risk of atherosclerosis. Alterations in FFAs are likely to depend on seizures control, and on VPA levels.

AB - This study reveals protective role of l-ascorbic acid (25, 50 and 100MUg/mL) against toxic impacts of acute sub-lethal exposure of Acephate (5MUg/mL) in a non target organism Drosophila melanogaster. Organismal effect was evident from increased impairment in climbing activities (9 folds) of treated individuals who also manifested altered ocular architecture. These anomalies were reduced with l ascorbic acid (l-AA) supplementation. Acephate induced apoptotic lesions in eye imaginal discs and gut confirmed tissue damage that also reduced with l-AA co treatment. Reduction in viability of fat body cells (~41%), neural cells (~42%) and hemocytes (3 folds) indicates cytotoxic and immunotoxic potential of Acephate, which were significantly mitigated with l-AA co-administration. The sub cellular toxic impacts of Acephate treatment became obvious from enhancement in activities of antioxidant enzymes (CAT by ~1.63 folds, SOD by ~1.32 folds), detoxifying enzymes (Cyp450 by ~1.99 folds and GST by ~1.34 folds), 2.1 times boost in HSP 70 expression, and inhibition of cholinesterase activity (by ~0.66 folds). DNA breaks evident through comet assay confirmed Acephate triggered genotoxicity which could also be prevented through co-administration of. L-AA Furthermore, the study proposes the use of Drosophila as a model to screen chemicals for their protective potential against pesticide toxicity. PMID- 27701060 TI - Zeolitic imidazolate framework-8 derived nanoporous carbon as an effective and recyclable adsorbent for removal of ciprofloxacin antibiotics from water. AB - The nanoporous carbons (NPC) derived from a one-step carbonization of zeolitic imidazolate framework-8 (ZIF-8) were synthesized and used for ciprofloxacin (CIP) removal from water. The resultant products were characterized by SEM, TEM, FT-IR, Raman, N2 adsorption-desorption analysis, XRD, TGA and Zeta potential. The optimized NPC-700 (carbonized at 700 degrees C for 2h) exhibited an optimal performance in CIP adsorption removal. CIP adsorption on NPC-700 as a function of contact time, initial CIP concentration, adsorbent dosage, pH, ionic strength and humic acid concentration were investigated. Kinetics of CIP removal was found to follow pseudo-second-order rate equation. Both Langmuir and Freundlich models fitted the adsorption data well and gave similar correlation coefficients (>0.96). However, Freundlich isotherm gave a better fit (r2=0.9969), suggesting a multilayer adsorption of CIP onto surface of NPC-700 adsorbent. The maximum adsorption capacity for CIP based on Langmuir model was 416.7mg/g, which was higher than those of other adsorbents. The NPC-700 material showed no apparent loss in CIP adsorption after seven cycles. These features reveal that the metal organic framework (MOF) derived NPC may be a promising adsorbent for CIP removal from water. PMID- 27701061 TI - Long-term stability of FeSO4 and H2SO4 treated chromite ore processing residue (COPR): Importance of H+ and SO42. AB - In this study, the long-term stability of Cr(VI) in the FeSO4 and H2SO4 (FeSO4 H2SO4) treated chromite ore processing residue (COPR) after 400 curing days and the stabilization mechanisms were investigated. FeSO4-H2SO4 treatment significantly reduced toxicity characteristic leaching procedure (TCLP) and synthetic precipitation leaching procedure (SPLP) Cr(VI) concentrations to lower than the regulatory limit of 1.5mgL-1 (HJ/T 301-2007, China EPA) even for the samples curing 400days, achieving an outstanding long-term stability. Our independent leaching tests revealed that H+ and SO42- have synergistic effect on promoting the release of Cr(VI), which would make Cr(VI) easier accessed by Fe(II) during stabilization. The contributions of H+ and SO42- to Cr(VI) release ratio were 25%-44% and 19%-38%, respectively, as 5mol H2SO4 per kg COPR was used. X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and alkaline digestion analyses were also employed to interpret the possible stabilization mechanism. Cr(VI) released from COPR solid was reduced to Cr(III) by Fe(II), and then formed stable FexCr(1-x)(OH)3 precipitate. This study provides a facile and reliable scheme for COPR stabilization, and verifies the excellent long-term stability of the FeSO4-H2SO4 treated COPR.

PMID- 27701063 TI - Physiological and sensory consequences of exercise oscillatory ventilation in heart failure-COPD. AB - BACKGROUND: Exercise oscillatory ventilation (EOV) is associated with poor ventilatory efficiency and higher operating lung volumes in heart failure. These abnormalities may be particularly deleterious to dyspnea and exercise tolerance in mechanically-limited patients, e.g. those with coexistent COPD. METHODS: Ventilatory, gas exchange and sensory responses to incremental exercise were contrasted in 68 heart failure-COPD patients (12 EOV+). EOV was established by standard criteria. RESULTS: Compared to EOV-, EOV+ had lower exercise capacity, worse ventilatory inefficiency and higher peak dyspnea scores (p<0.05). Peak capillary PCO2 (PcCO2) was higher and end-tidal CO2 (PETCO2) was lower in EOV+. Thus, greater (i.e., more positive) P(c-ET)CO2 and dead space/tidal volume values were found in these patients compared to EOV- (p<0.05). Ventilatory inefficiency was related to increased dead space/tidal volume in EOV+ (r=0.74; p<0.01). Owing to higher operating lung volumes, inspiratory reserve volume (IRV) decreased to a greater extent in EOV+. Tidal volume oscillations consistently ceased when a "critical" IRV was reached (~0.3-0.5L); thereafter, PcCO2 stabilized or increased and dyspnea scores rose sharply. Exercise capacity was closely related to IRV decrements and peak dyspnea in EOV+ (r=-0.78 and 0.84, respectively; p<0.01). CONCLUSIONS: Dyspnea and exercise tolerance are negatively influenced by EOV in heart failure patients presenting with COPD as co-morbidity. Pharmacological and non-pharmacological interventions known to decrease EOV might prove particularly valuable to mitigate symptom burden and exercise intolerance in this specific heart failure group. PMID- 27701065 TI - Informing Estimates of Program Effects for Studies of Mathematics Professional Development Using Teacher Content Knowledge Outcomes. AB - Mathematics professional development is widely offered, typically with the goal of improving teachers' content knowledge, the quality of teaching, and ultimately students' achievement. Recently, new assessments focused on mathematical knowledge for teaching (MKT) have been developed to assist in the evaluation and improvement of mathematics professional development. This study presents empirical estimates of average program change in MKT and its variation with the goal of supporting the design of experimental trials that are adequately powered to detect a specified program effect. The study drew on a large database representing five different assessments of MKT and collectively 326 professional development programs and 9,365 teachers. Results from cross-classified hierarchical growth models found that standardized average change estimates across the five assessments ranged from a low of 0.16 standard deviations (SDs) to a high of 0.26 SDs. Power analyses using the estimated pre- and posttest change estimates indicated that hundreds of teachers are needed to detect changes in knowledge at the lower end of the distribution. Even studies powered to detect effects at the higher end of the distribution will require substantial resources to conduct rigorous experimental trials. Empirical benchmarks that describe average program change and its variation provide a useful preliminary resource for interpreting the relative magnitude of effect sizes associated with professional development programs and for designing adequately powered trials. PMID- 27701064 TI - Overcoming Addictions, a Web-Based Application, and SMART Recovery, an Online and In-Person Mutual Help Group for Problem Drinkers, Part 2: Six-Month Outcomes of a Randomized Controlled Trial and Qualitative Feedback From Participants. AB - BACKGROUND: Despite empirical evidence supporting the use of Web-based interventions for problem drinking, much remains unknown about factors that influence their effectiveness. OBJECTIVE: We evaluated the performance of 2 resources for people who want to achieve and maintain abstinence: SMART Recovery (SR) and Overcoming Addictions (OA). OA is a Web application based on SR. We also examined participant and intervention-related factors hypothesized to impact clinical outcomes of Web-based interventions. METHODS: We recruited 189 heavy drinkers through SR's website and in-person meetings throughout the United States. We began by randomly assigning participants to (1) SR meetings alone, (2) OA alone, and (3) OA and SR (OA+SR). Recruitment challenges compelled us to assign participants only to SR (n=86) or OA+SR (n=102). The experimental hypotheses were as follows: (1) Both groups will reduce their drinking and alcohol-related consequences at follow-up compared with their baseline levels, and (2) The OA+SR condition will reduce their drinking and alcohol or drug related consequences more than the SR only condition. Additionally, we derived 3 groups empirically (SR, OA, and OA+SR) based on the participants' actual use of each intervention and conducted analyses by comparing them. Primary outcome measures included percent days abstinent (PDA), mean drinks per drinking day (DDD), and alcohol or drug-related consequences. Postbaseline assessments were conducted by phone at 3 and 6 months. Secondary analyses explored whether clinical issues (eg, severity of alcohol problems, level of distress, readiness to change) or intervention-related factors (eg, Internet fluency, satisfaction with site) affected outcomes. RESULTS: Both intent-to-treat analyses and the actual-use analyses showed highly significant improvement from baseline to follow ups for all 3 groups. Mean within-subject effect sizes were large (d>0.8) overall. There was no significant difference between groups in the amount of improvement from baseline to the average of the follow-ups. We found that participants who stopped drinking before joining the clinical trial had significantly better outcomes than participants who were still drinking when they joined the study. Neither Internet fluency nor participants' reported ease of navigating the site had an impact on outcomes. CONCLUSIONS: These results support our first experimental hypothesis but not the second. On average, participants improved on all dependent measures. Both SR and OA helped participants recover from their problem drinking. Web-based interventions can help even those individuals with lengthy histories of heavy drinking to make clinically significant reductions in their consumption and related problems. These interventions work well for individuals in the action stage of change.

PMID- 27701066 TI - Ferritin and iron studies in anaemia and chronic disease. AB - Anaemia is a condition in which the number of red cells necessary to meet the body's physiological requirements is insufficient. Iron deficiency anaemia and the anaemia of chronic disease are the two most common causes of anaemia worldwide;1 iron homeostasis plays a pivotal role in the pathogenesis of both diseases. An understanding of how iron studies can be used to distinguish between these diseases is therefore essential not only for diagnosis but also in guiding management. This review will primarily focus on iron deficiency anaemia and anaemia of chronic disease; however, iron overload in anaemia will also be briefly discussed.

PMID- 27701070 TI - ESMO consensus conference on malignant lymphoma: general perspectives and recommendations for prognostic tools in mature B-cell lymphomas and chronic lymphocytic leukaemia. AB - The European Society for Medical Oncology (ESMO) consensus conference on mature B cell lymphomas and chronic lymphocytic leukaemia (CLL) was held on 20 June 2015 in Lugano, Switzerland, and included a multidisciplinary panel of 25 leading experts. The aim of the conference was to develop recommendations on critical subjects difficult to consider in detail in the ESMO Clinical Practice Guidelines. The following areas were identified: (i) the elderly patient, (ii) prognostic factors suitable for clinical use and (iii) the 'ultra-high-risk' group. Before the conference, the expert panel was divided into three working groups; each group focused on one of these areas in order to address four clinically relevant questions relating to that topic. All relevant scientific literature, as identified by the experts, was reviewed in advance. During the consensus conference, each working group developed recommendations to address each of the four questions assigned to their group. These recommendations were then presented to the entire panel and a consensus was reached. This manuscript presents recommendations dedicated to the second area of interest, i.e. prognostic factors suitable for clinical use. The four topics [i.e. interim positron emission tomography (PET), TP53 mutations, cell of origin (COO) and minimal residual disease (MRD)] were primarily chosen because of the bulk of available data together with the lack of clear guidance regarding their use in clinical practice and within clinical trials. Results, including a summary of evidence supporting each recommendation, are detailed in this manuscript. The panel acknowledged that detection of TP53 inactivation by deletion or mutation in CLL should be implemented in clinical practice (level of evidence I, strength of recommendation A). Due to their potentially high prognostic value, at least in some lymphoma entities, implementation of interim PET, COO and MRD was highly recommended in the context of clinical trials. All expert panel members approved this final article. PMID- 27701074 TI - CeNDR, the Caenorhabditis elegans natural diversity resource. AB - Studies in model organisms have yielded considerable insights into the etiology of disease and our understanding of evolutionary processes. Caenorhabditis elegans is among the most powerful model organisms used to understand biology. However, C. elegans is not used as extensively as other model organisms to investigate how natural variation shapes traits, especially through the use of genome-wide association (GWA) analyses. Here, we introduce a new platform, the C. elegans Natural Diversity Resource (CeNDR) to enable statistical genetics and genomics studies of C. elegans and to connect the results to human disease. CeNDR provides the research community with wild strains, genome-wide sequence and variant data for every strain, and a GWA mapping portal for studying natural variation in C. elegans Additionally, researchers outside of the C. elegans community can benefit from public mappings and integrated tools for comparative analyses. CeNDR uses several databases that are continually updated through the addition of new strains, sequencing data, and association mapping results. The CeNDR data are accessible through a freely available web portal located at http://www.elegansvariation.org or through an application programming interface. PMID- 27701075 TI - A double-strand break can trigger immunoglobulin gene conversion. AB - All three B cell-specific activities of the immunoglobulin (Ig) gene re-modeling system-gene conversion, somatic hypermutation and class switch recombination require activation-induced deaminase (AID). AID-induced DNA lesions must be further processed and dissected into different DNA recombination pathways. In order to characterize potential intermediates for Ig gene conversion, we inserted an I-SceI recognition site into the complementarity determining region 1 (CDR1) of the Ig light chain locus of the AID knockout DT40 cell line, and conditionally expressed I-SceI endonuclease. Here, we show that a double-strand break (DSB) in CDR1 is sufficient to trigger Ig gene conversion in the absence of AID. The pattern and pseudogene usage of DSB-induced gene conversion were comparable to those of AID-induced gene conversion; surprisingly, sometimes a single DSB induced multiple gene conversion events. These constitute direct evidence that a DSB in the V region can be an intermediate for gene conversion. The fate of the DNA lesion downstream of a DSB had more flexibility than that of AID, suggesting two alternative models: (i) DSBs during the physiological gene conversion are in the minority compared to single-strand breaks (SSBs), which are frequently generated following DNA deamination, or (ii) the physiological gene conversion is mediated by a tightly regulated DSB that is locally protected from non-homologous end joining (NHEJ) or other non-homologous DNA recombination machineries. PMID- 27701077 TI - Evaluation and improvement of a single nucleotide polymorphism-based PCR assay for rapid differentiation of live attenuated vaccine strains from field isolates of Erysipelothrix rhusiopathiae. AB - A single nucleotide polymorphism-based PCR assay has been developed to differentiate the attenuated vaccine strain used in Japan from field isolates of Erysipelothrix rhusiopathiae found in pigs. However, this assay has been evaluated with only Japanese strains and isolates; therefore, it is unknown whether it could be used in other countries with E. rhusiopathiae strains and isolates of different genetic backgrounds. In our study, the PCR assay was evaluated using Chinese E. rhusiopathiae vaccine strains and field isolates. The PCR assay was able to differentiate the attenuated vaccine strains from the field isolates of E. rhusiopathiae in China but with a pattern different from that observed in Japan (only a single nucleotide polymorphism was detected in the Chinese vaccine strains compared with 5 in the Japanese vaccine strains). Importantly, either a DNA polymerase without 3' to 5' exonuclease activity or an exo+ polymerase with an antibody inhibiting the proofreading activity was required. In conclusion, after evaluation and improvement, this fast differentiation assay can be extended from Japan to China. PMID- 27701078 TI - Spontaneous reproductive pathology in female guinea pigs. AB - Reproductive pathology of domestic guinea pigs is underreported to date. To provide a comprehensive review of uterine disease in guinea pigs, we performed a retrospective study of the pathology archives of the University of Tennessee, College of Veterinary Medicine. By histology, 13 of 37 uterine lesions in 23 animals were neoplastic; the other 24 nonneoplastic lesions included cystic endometrial hyperplasia (16 of 24), endometrial hemorrhage (3 of 24), pyometra (2 of 24), polyp (2 of 24), and mucometra (1 of 24). The most common guinea pig uterine neoplasms were uterine leiomyomas (6 of 13), followed by adenomas (3 of 13) and leiomyosarcomas (1 of 13). Other neoplasms included anaplastic tumors of unknown origin (2 of 13) and choriocarcinoma (1 of 13). Both anaplastic tumors and the choriocarcinoma were positive for vimentin. The choriocarcinoma was positive for HSD83B1, indicating a trophoblastic origin and its final diagnosis. All were negative for cytokeratin and smooth muscle. In multiple animals, more than 1 tumor or lesion was reported. Estrogen receptor and progesterone receptor expression was nearly 100% in uterine neoplasms. Nearly all animals for which data were available had cystic rete ovarii (18 of 19); the animal with no cystic rete ovarii had paraovarian cysts. In our study, female pet guinea pigs had a tendency to develop cystic endometrial hyperplasia and uterine neoplasia. Factors for the development of these lesions could be cystic rete ovarii, hormone dysregulation, and/or age. Other factors could contribute to the development of uterine lesions. As in other species, early ovariohysterectomy could decrease the prevalence of uterine lesions. PMID- 27701076 TI - Laboratory evolution of artificially expanded DNA gives redesignable aptamers that target the toxic form of anthrax protective antigen. AB - Reported here is a laboratory in vitro evolution (LIVE) experiment based on an artificially expanded genetic information system (AEGIS). This experiment delivers the first example of an AEGIS aptamer that binds to an isolated protein target, the first whose structural contact with its target has been outlined and the first to inhibit biologically important activities of its target, the protective antigen from Bacillus anthracis We show how rational design based on secondary structure predictions can also direct the use of AEGIS to improve the stability and binding of the aptamer to its target. The final aptamer has a dissociation constant of ~35 nM. These results illustrate the value of AEGIS-LIVE for those seeking to obtain receptors and ligands without the complexities of medicinal chemistry, and also challenge the biophysical community to develop new tools to analyze the spectroscopic signatures of new DNA folds that will emerge in synthetic genetic systems replacing standard DNA and RNA as platforms for LIVE. PMID- 27701079 TI - Heart Failure Therapy in 2016: SHIFTing the PARADIGM From Antiquated Therapies Toward Novel Agents. AB - Heart failure (HF) continues to afflict millions of Americans, resulting in substantial clinical and economic burden to our society. Recent literature has highlighted the role of 2 novel therapies (an angiotensin receptor blocker/neprilysin inhibitor and ivabradine) in further reducing residual disease in HF. Simultaneously, evidence has mounted suggesting that older therapies like digoxin are not effective in contemporary practice and, in fact, may be harmful. This editorial summarizes the most recently published articles pertaining to both new and old HF therapies and provides a call to action to pharmacists on how to shift patients toward effective drug regimens. PMID- 27701080 TI - Cobimetinib. AB - OBJECTIVE: To review and summarize data on cobimetinib, which was approved by the US Food and Drug Administration (FDA) in November 2015 for use in combination with vemurafenib for unresectable or metastatic melanoma with a BRAFV600E or V600K mutation. DATA SOURCES: A literature search using PubMed was conducted using the terms cobimetinib, MEK inhibitor, and melanoma from January 2000 to June 2016. STUDY SELECTION AND DATA EXTRACTION: The literature search was confined to human studies published in English. Trials of cobimetinib for melanoma were prioritized. DATA SYNTHESIS: Cobimetinib is a reversible inhibitor of MEK1 and MEK2. Its FDA approval was based on a phase III, randomized trial of vemurafenib monotherapy (n = 248) or vemurafenib and cobimetinib (n = 247) in unresectable stage IIIC or IV melanoma with a BRAFV600 mutation. Cobimetinib was administered as 60 mg orally daily for 21 days/7 days off, whereas vemurafenib was administered as 960 mg twice daily. Vemurafenib and cobimetinib were associated with an objective response rate of 68%, and median progression-free survival of 9.9 months. The overall survival was not reached at the time of first interim analysis. Clinically relevant grade >=3 adverse events were diarrhea (6%), rash (6%), photosensitivity (2%), elevated liver function tests (LFTs) (8% 12%), increased creatine kinase (11%), and retinal detachment (3%). CONCLUSION: Cobimetinib combined with vemurafenib is an alternative BRAF/MEK inhibitor therapy for unresectable or metastatic melanoma with BRAFV600 mutation. The role of cobimetinib in melanoma and other solid tumors is likely to expand as the results from ongoing studies become available. PMID- 27701082 TI - The Predictive Role of Maternal Parenting and Stress on Pupils' Bullying involvement. AB - The link between inappropriate parenting style and both bullying and victimization is well documented. However, it is not clear as to which kind of parenting style is associated with victimization. Furthermore, no studies have yet been conducted regarding the role of parental stress in bullying and victimization. This study aimed to examine the role of parenting styles and maternal stress in pupils' bullying and victimization. A total of 300 primary school pupils, enrolled in fourth and fifth grades, participated in the study. Initially, 100 noninvolved pupils were randomly selected using a multistage cluster sampling method. Then using a screening method, 100 bully pupils and 100 victimized peers were selected. Olweus Bullying Scale and teacher nomination were administered for screening these pupils. Baumrind Parenting Style Questionnaire and revised version of Abidin Parental Stress Index (short form) were also applied to all pupils in the study. Data were analyzed using discriminant function analysis. The findings showed that (a) with regard to parenting styles, significant differences were found among groups. Authoritarian parenting style could significantly predict pupils' bullying behavior, whereas victimization was predictable in families with permissive parenting style. In addition, noninvolved pupils were predicted to have authoritative parenting style. (b) Considering maternal stress, significant differences were observed across groups. Parents of bullies and victims were predicted to have higher maternal stress than noninvolved pupils. The implications of the study in relation to the role of mothers in bullying and victimization are discussed. PMID- 27701081 TI - Interaction Between Low-Dose Methotrexate and Nonsteroidal Anti-inflammatory Drugs, Penicillins, and Proton Pump Inhibitors. AB - OBJECTIVE: To review the potential drug interactions between low-dose methotrexate (LD-MTX) and nonsteroidal anti-inflammatory drugs (NSAIDs), penicillins, and proton-pump inhibitors (PPIs) given the disparity between interactions reported for high-dose and low-dose MTX to help guide clinicians. DATA SOURCES: A literature search was performed in MEDLINE (1946 to September 2016), EMBASE (1974 to September 2016), and International Pharmaceutical Abstracts (1970 to January 2015) to identify reports describing potential drug interactions between LD-MTX and NSAIDS, penicillins, or PPIs. Reference lists of included articles were reviewed to find additional eligible articles. STUDY SELECTION AND DATA EXTRACTION: All English-language observational, randomized, and pharmacokinetic (PK) studies assessing LD-MTX interactions in humans were analyzed to determine clinical relevance in making recommendations to clinicians. Clinical case reports were assigned a Drug Interaction Probability Scale score. DATA SYNTHESIS: A total of 32 articles were included (28 with NSAIDs, 3 with penicillins, and 2 with PPIs [1 including both PPI and NSAID]). Although there are some PK data to describe increased LD-MTX concentrations when NSAIDs are used concomitantly, the clinical relevance remains unclear. Based on the limited data on LD-MTX with penicillins and PPIs, no clinically meaningful interaction was identified. CONCLUSION: Given the available evidence, the clinical importance of the interaction between LD-MTX and NSAIDs, penicillins, and PPIs cannot be substantiated. Health care providers should assess the benefit and risk of LD-MTX regardless of concomitant drug use, including factors known to predispose patients to MTX toxicity, and continue to monitor clinical and laboratory parameters per guideline recommendations. PMID- 27701083 TI - Reactive Protection? Fear, Victimization, and Fighting Among U.S. High School Students. AB - Youth violence in high schools is a pervasive and persistent problem in the United States. Students engage in physical fights, experience bullying and teen dating violence (TDV), are threatened with weapons, and miss school due to safety concerns. However, despite theoretical support, research has not sufficiently addressed the relationship between students' fear and fighting at school. This secondary analysis used data from the 2013 Youth Risk Behavior Survey ( n = 13,583) to examine the relationship between fear at school, victimization, and engagement in fighting at school among high school students. We created a 3-item composite fear variable, conducted logistic regression to examine likelihood of fighting, and multinomial regression to examine risk for multiple fights, and stratified all models by gender. Findings indicate that both male and female students who experienced fear were more likely to engage in fights at school than peers who did not experience fear, even when controlling for other factors. Likewise, the more fear incidents a student experienced, the more at risk they were for engaging in multiple fights. Findings on victimization indicate that the relationship with fighting is more straightforward for male students than for female students. For males, being bullied and experiencing multiple incidents of physical and sexual TDV were all associated with fighting at school. For females, however, only one type of victimization was associated with fighting at school: experiencing multiple incidents of physical TDV. Overall, findings suggest that fear may be more than merely a by-product of fighting, but rather-as the extant research supports-fear also can be generalized across situations and displayed through patterns of aggression. Findings support the need for interventions aimed at skill-building in areas of communication, emotion regulation, conflict resolution, and healthy relationships to help youth-particularly those in younger grades-negotiate interpersonal relationships without the use of violence. PMID- 27701084 TI - Factor VII Deficiency: From Basics to Clinical Laboratory Diagnosis and Patient Management. AB - Factor VII (FVII) deficiency is a rare inheritable bleeding disorder affecting 1/500 000 individuals. Clinical manifestations are heterogeneous, from asymptomatic to severe and potentially fatal bleeding. These clinical manifestations do not correlate well with FVII plasma levels. For this reason, FVII-deficient patient management during surgery or for long-term prophylaxis remains challenging. Laboratory testing for FVII activity is, however, the first line method for FVII deficiency diagnosis and is helpful for managing patients in combination with clinical history. Additional testing consists of FVII immunoassay and genetic testing. Genetic abnormalities on the FVII gene are heterogeneous and can translate into quantitative or qualitative defects. Some of the latter can react differently with different thromboplastins; this can be misleading for the laboratory as no consensus exists at present on an FVII deficiency diagnosis methodology. Indeed, no single test is able to predict accurately the bleeding risk. This review provides a broad picture of inherited and acquired FVII deficiency with a particular focus on laboratory diagnosis. PMID- 27701085 TI - Detection of local H2O exposed at the surface of Ceres. AB - The surface of dwarf planet Ceres contains hydroxyl-rich materials. Theories predict a water ice-rich mantle, and water vapor emissions have been observed, yet no water (H2O) has been previously identified. The Visible and InfraRed (VIR) mapping spectrometer onboard the Dawn spacecraft has now detected water absorption features within a low-illumination, highly reflective zone in Oxo, a 10-kilometer, geologically fresh crater, on five occasions over a period of 1 month. Candidate materials are H2O ice and mineral hydrates. Exposed H2O ice would become optically undetectable within tens of years under current Ceres temperatures; consequently, only a relatively recent exposure or formation of H2O would explain Dawn's findings. Some mineral hydrates are stable on geological time scales, but their formation would imply extended contact with ice or liquid H2O. PMID- 27701086 TI - Distribution of phyllosilicates on the surface of Ceres. AB - The dwarf planet Ceres is known to host phyllosilicate minerals at its surface, but their distribution and origin have not previously been determined. We used the spectrometer onboard the Dawn spacecraft to map their spatial distribution on the basis of diagnostic absorption features in the visible and near-infrared spectral range (0.25 to 5.0 micrometers). We found that magnesium- and ammonium bearing minerals are ubiquitous across the surface. Variations in the strength of the absorption features are spatially correlated and indicate considerable variability in the relative abundance of the phyllosilicates, although their composition is fairly uniform. These data, along with the distinctive spectral properties of Ceres relative to other asteroids and carbonaceous meteorites, indicate that the phyllosilicates were formed endogenously by a globally widespread and extensive alteration process. PMID- 27701087 TI - Cryovolcanism on Ceres. AB - Volcanic edifices are abundant on rocky bodies of the inner solar system. In the cold outer solar system, volcanism can occur on solid bodies with a water-ice shell, but derived cryovolcanic constructs have proved elusive. We report the discovery, using Dawn Framing Camera images, of a landform on dwarf planet Ceres that we argue represents a viscous cryovolcanic dome. Parent material of the cryomagma is a mixture of secondary minerals, including salts and water ice. Absolute model ages from impact craters reveal that extrusion of the dome has occurred recently. Ceres' evolution must have been able to sustain recent interior activity and associated surface expressions. We propose salts with low eutectic temperatures and thermal conductivities as key drivers for Ceres' long term internal evolution.

The dwarf planet is dominated by numerous craters, but other features are also common. Linear structures include both those associated with impact craters and those that do not appear to have any correlation to an impact event. Abundant lobate flows are identified, and numerous domical features are found at a range of scales. Features suggestive of near-surface ice, cryomagmatism, and cryovolcanism have been identified. Although spectroscopic analysis has currently detected surface water ice at only one location on Ceres, the identification of these potentially ice-related features suggests that there may be at least some ice in localized regions in the crust.

AB - Thermochemical models have predicted that Ceres, is to some extent, differentiated and should have an icy crust with few or no impact craters. We present observations by the Dawn spacecraft that reveal a heavily cratered surface, a heterogeneous crater distribution, and an apparent absence of large craters. The morphology of some impact craters is consistent with ice in the subsurface, which might have favored relaxation, yet large unrelaxed craters are also present. Numerous craters exhibit polygonal shapes, terraces, flowlike features, slumping, smooth deposits, and bright spots. Crater morphology and simple-to-complex crater transition diameters indicate that the crust of Ceres is neither purely icy nor rocky. By dating a smooth region associated with the Kerwan crater, we determined absolute model ages (AMAs) of 550 million and 720 million years, depending on the applied chronology model.

AB - On 6 March 2015, Dawn arrived at Ceres to find a dark, desiccated surface punctuated by small, bright areas. Parts of Ceres' surface are heavily cratered, but the largest expected craters are absent. Ceres appears gravitationally relaxed at only the longest wavelengths, implying a mechanically strong lithosphere with a weaker deep interior. Ceres' dry exterior displays hydroxylated silicates, including ammoniated clays of endogenous origin. The possibility of abundant volatiles at depth is supported by geomorphologic features such as flat crater floors with pits, lobate flows of materials, and a singular mountain that appears to be an extrusive cryovolcanic dome. On one occasion, Ceres temporarily interacted with the solar wind, producing a bow shock accelerating electrons to energies of tens of kilovolts.

AB - Oxygen electrochemistry plays a key role in renewable energy technologies such as fuel cells and electrolyzers, but the slow kinetics of the oxygen evolution reaction (OER) limit the performance and commercialization of such devices. Here we report an iridium oxide/strontium iridium oxide (IrOx/SrIrO3) catalyst formed during electrochemical testing by strontium leaching from surface layers of thin films of SrIrO3 This catalyst has demonstrated specific activity at 10 milliamps per square centimeter of oxide catalyst (OER current normalized to catalyst surface area), with only 270 to 290 millivolts of overpotential for 30 hours of continuous testing in acidic electrolyte. Density functional theory calculations suggest the formation of highly active surface layers during strontium leaching with IrO3 or anatase IrO2 motifs. The IrOx/SrIrO3 catalyst outperforms known IrOx and ruthenium oxide (RuOx) systems, the only other OER catalysts that have reasonable activity in acidic electrolyte.

AB - Direct methods for stereoselective functionalization of sp3-hybridized carbon hydrogen [C(sp3)-H] bonds in complex organic molecules could facilitate much more efficient preparation of therapeutics and agrochemicals. Here, we report a copper catalyzed radical relay pathway for enantioselective conversion of benzylic C-H bonds into benzylic nitriles. Hydrogen-atom abstraction affords an achiral benzylic radical that undergoes asymmetric C(sp3)-CN bond formation upon reaction with a chiral copper catalyst. The reactions proceed efficiently at room temperature with the benzylic substrate as limiting reagent, exhibit broad substrate scope with high enantioselectivity (typically 90 to 99% enantiomeric excess), and afford products that are key precursors to important bioactive molecules. Mechanistic studies provide evidence for diffusible organic radicals and highlight the difference between these reactions and C-H oxidations mediated by enzymes and other catalysts that operate via radical rebound pathways. PMID- 27701110 TI - Radiative human body cooling by nanoporous polyethylene textile. AB - Thermal management through personal heating and cooling is a strategy by which to expand indoor temperature setpoint range for large energy saving. We show that nanoporous polyethylene (nanoPE) is transparent to mid-infrared human body radiation but opaque to visible light because of the pore size distribution (50 to 1000 nanometers). We processed the material to develop a textile that promotes effective radiative cooling while still having sufficient air permeability, water wicking rate, and mechanical strength for wearability. We developed a device to simulate skin temperature that shows temperatures 2.7 degrees and 2.0 degrees C lower when covered with nanoPE cloth and with processed nanoPE cloth, respectively, than when covered with cotton. Our processed nanoPE is an effective and scalable textile for personal thermal management. PMID- 27701112 TI - Plant development regulated by cytokinin sinks. AB - Morphogenetic signals control the patterning of multicellular organisms. Cytokinins are mobile signals that are perceived by subsets of plant cells. We found that the responses to cytokinin signaling during Arabidopsis development are constrained by the transporter PURINE PERMEASE 14 (PUP14). In our experiments, the expression of PUP14 was inversely correlated to the cytokinin signaling readout. Loss of PUP14 function allowed ectopic cytokinin signaling accompanied by aberrant morphogenesis in embryos, roots, and the shoot apical meristem. PUP14 protein localized to the plasma membrane and imported bioactive cytokinins, thus depleting apoplastic cytokinin pools and inhibiting perception by plasma membrane-localized cytokinin sensors to create a sink for active ligands. We propose that the spatiotemporal cytokinin sink patterns established by PUP14 determine the cytokinin signaling landscape that shapes the morphogenesis of land plants. PMID- 27701111 TI - Ligand-accelerated enantioselective methylene C(sp3)-H bond activation. AB - Effective differentiation of prochiral carbon-hydrogen (C-H) bonds on a single methylene carbon via asymmetric metal insertion remains a challenge. Here, we report the discovery of chiral acetyl-protected aminoethyl quinoline ligands that enable asymmetric palladium insertion into prochiral C-H bonds on a single methylene carbon center. We apply these palladium complexes to catalytic enantioselective functionalization of beta-methylene C-H bonds in aliphatic amides. Using bidentate ligands to accelerate C-H activation of otherwise unreactive monodentate substrates is crucial for outcompeting the background reaction driven by substrate-directed cyclopalladation, thereby avoiding erosion of enantioselectivity. The potential of ligand acceleration in C-H activation is also demonstrated by enantioselective beta-C-H arylation of simple carboxylic acids without installing directing groups. PMID- 27701113 TI - Benefits and risks of the Sanofi-Pasteur dengue vaccine: Modeling optimal deployment. AB - The first approved dengue vaccine has now been licensed in six countries. We propose that this live attenuated vaccine acts like a silent natural infection in priming or boosting host immunity. A transmission dynamic model incorporating this hypothesis fits recent clinical trial data well and predicts that vaccine effectiveness depends strongly on the age group vaccinated and local transmission intensity. Vaccination in low-transmission settings may increase the incidence of more severe "secondary-like" infection and, thus, the numbers hospitalized for dengue. In moderate transmission settings, we predict positive impacts overall but increased risks of hospitalization with dengue disease for individuals who are vaccinated when seronegative. However, in high-transmission settings, vaccination benefits both the whole population and seronegative recipients. Our analysis can help inform policy-makers evaluating this and other candidate dengue vaccines. PMID- 27701115 TI - Thanks to the glass ceiling breakers. PMID- 27701114 TI - Instantaneous ion configurations in the K+ ion channel selectivity filter revealed by 2D IR spectroscopy. AB - Potassium channels are responsible for the selective permeation of K+ ions across cell membranes. K+ ions permeate in single file through the selectivity filter, a narrow pore lined by backbone carbonyls that compose four K+ binding sites. Here, we report on the two-dimensional infrared (2D IR) spectra of a semisynthetic KcsA channel with site-specific heavy (13C18O) isotope labels in the selectivity filter. The ultrafast time resolution of 2D IR spectroscopy provides an instantaneous snapshot of the multi-ion configurations and structural distributions that occur spontaneously in the filter. Two elongated features are resolved, revealing the statistical weighting of two structural conformations. The spectra are reproduced by molecular dynamics simulations of structures with water separating two K+ ions in the binding sites, ruling out configurations with ions occupying adjacent sites.

AB - BACKGROUND: Pulmonary hypertension (PH) is frequently observed in patients with acute respiratory distress syndrome (ARDS) and it is associated with an increased risk of mortality. Both acid sphingomyelinase (aSMase) activity and interleukin 6 (IL-6) levels are increased in patients with sepsis and correlate with worst outcomes, but their role in pulmonary vascular dysfunction pathogenesis has not yet been elucidated. Therefore, the aim of this study was to determine the potential contribution of aSMase and IL-6 in the pulmonary vascular dysfunction induced by lipopolysaccharide (LPS). METHODS: Rat or human pulmonary arteries (PAs) or their cultured smooth muscle cells (SMCs) were exposed to LPS, SMase or IL-6 in the absence or presence of a range of pharmacological inhibitors. The effects of aSMase inhibition in vivo with D609 on pulmonary arterial pressure and inflammation were assessed following intratracheal administration of LPS. RESULTS: LPS increased ceramide and IL-6 production in rat pulmonary artery smooth muscle cells (PASMCs) and inhibited pulmonary vasoconstriction induced by phenylephrine or hypoxia (HPV), induced endothelial dysfunction and potentiated the contractile responses to serotonin. Exogenous SMase and IL-6 mimicked the effects of LPS on endothelial dysfunction, HPV failure and hyperresponsiveness to serotonin in PA; whereas blockade of aSMase or IL-6 prevented LPS-induced effects. Finally, administration of the aSMase inhibitor D609 limited the development of endotoxin-induced PH and ventilation-perfusion mismatch. The protective effects of D609 were validated in isolated human PAs. CONCLUSIONS: Our data indicate that aSMase and IL-6 are not simply biomarkers of poor outcomes but pathogenic mediators of pulmonary vascular dysfunction in ARDS secondary to Gram negative infections. PMID- 27701118 TI - CTAS: a CT score to quantify disease activity in pulmonary sarcoidosis. AB - BACKGROUND: A major gap in the management of sarcoidosis is the lack of accessible and objective methods to measure disease activity. Since 90% of patients have pulmonary involvement, we explored if a disease activity score based on thoracic CT scans could address this clinical issue. METHODS: High resolution CT scans from 100 consecutive patients with sarcoidosis at a regional sarcoidosis service were scored for extent of CT abnormalities known to relate to granuloma or lymphocytic infiltration from published CT-pathological studies. These individual abnormality scores were then correlated against serum ACE, sIL 2R and change in FVC to identify CT abnormalities that reflect contemporaneous disease activity. The sum of these scores, or CT Activity Score (CTAS), was then validated against FVC response to treatment. FINDINGS: CT extent scores for nodularity, ground-glass opacification, interlobular septal thickening and consolidation correlated significantly with at least one of the disease activity parameters and were used to form CTAS. CTAS was found to predict FVC response to treatment at 1 year and was highly reproducible between radiologists. An abbreviated CTAS (aCTAS), constructed from presence or absence of the four CT abnormalities, also showed significant correlation with FVC response to treatment. CTAS and aCTAS also correlated with response to treatment in the fibrotic subgroup. INTERPRETATION: CTAS provides a concept for an objective and reproducible CT scoring method to quantify disease activity in sarcoidosis. The score can potentially be used to stratify patients according to disease activity, determine response to treatment and establish if fibrotic sarcoidosis is active. PMID- 27701119 TI - Molecular Impact of Electronic Cigarette Aerosol Exposure in Human Bronchial Epithelium. AB - Little evidence is available regarding the physiological effects of exposure to electronic cigarette (ECIG) aerosol. We sought to determine the molecular impact of ECIG aerosol exposure in human bronchial epithelial cells (HBECs). Gene expression profiling was conducted in primary grown at air liquid interface and exposed to 1 of 4 different ECIG aerosols, traditional tobacco cigarette (TCIG) smoke, or clean air. Findings were validated experimentally with quantitative polymerase chain reaction and a reactive oxygen species immunoassay. Using gene set enrichment analysis, signatures of in vitro ECIG exposure were compared with those generated from bronchial epithelial brushings of current TCIG smokers and former TCIG smokers currently using ECIGs. We found 546 genes differentially expressed across the ECIG, TCIG, and air-exposed groups of HBECs (ANOVA; FDR q < .05; fold change > 1.5). A subset of these changes were shared between TCIG- and ECIG-exposed HBECs. ECIG exposure induced genes involved in oxidative and xenobiotic stress pathways and increased a marker of reactive oxygen species production in a dose-dependent manner. ECIG exposure decreased expression of genes involved in cilia assembly and movement. Furthermore, gene-expression differences observed in vitro were concordant with differences observed in airway epithelium collected from ECIG users (q < .01). In summary, our data suggest that ECIG aerosol can induce gene-expression changes in bronchial airway epithelium in vitro, some of which are shared with TCIG smoke. These changes were generally less pronounced than the effects of TCIG exposure and were more pronounced in ECIG products containing nicotine than those without nicotine. Our data further suggest that the gene-expression alterations seen with the in vitro exposure system reflects the physiological effects experienced in vivo by ECIG users.

AB - BACKGROUND: Cold plasma skin welding is a novel technology that bonds skin edges through soldering without the use of synthetic materials or conventional wound approximation methods such as sutures, staples, or skin adhesives. The cold plasma welding system uses a biological solder applied to the edges of a skin incision, followed by the application of cold plasma energy. The objectives of this study were to assess the feasibility of a cold plasma welding system in approximating and fixating skin incisions compared with conventional methods and to evaluate and define optimal plasma welding parameters and histopathological tissue response in a porcine model. METHODS AND MATERIALS: The cold plasma welding system (BioWeld1 System, IonMed Ltd, Yokneam, Israel) was used on porcine skin incisions using variable energy parameters. Wound healing was compared macroscopically and histologically to incisions approximated with sutures. RESULTS: When compared to sutured skin closure, cold plasma welding in specific system parameters demonstrated comparable and favorable wound healing results histopathologically as well as macroscopically. No evidence of epidermal damage, thermal or otherwise, was encountered in the specified parameters. Notably, bleeding, infection, and wound dehiscence were not detected at incision sites. Skin incisions welded at extreme energy parameters presented second-degree burns. CONCLUSION: Implementation of cold plasma welding has been shown to be feasible for skin closure. Initial in vivo results suggest cold plasma welding might provide equal, if not better, healing results than traditional methods of closure. PMID- 27701120 TI - Comprehensive Translational Assessment of Human-Induced Pluripotent Stem Cell Derived Cardiomyocytes for Evaluating Drug-Induced Arrhythmias. AB - Induced pluripotent stem cell-derived cardiomyocytes (iPSC-CM) hold promise for assessment of drug-induced arrhythmias and are being considered for use under the comprehensive in vitro proarrhythmia assay (CiPA). We studied the effects of 26 drugs and 3 drug combinations on 2 commercially available iPSC-CM types using high-throughput voltage-sensitive dye and microelectrode-array assays being studied for the CiPA initiative and compared the results with clinical QT prolongation and torsade de pointes (TdP) risk. Concentration-dependent analysis comparing iPSC-CMs to clinical trial results demonstrated good correlation between drug-induced rate-corrected action potential duration and field potential duration (APDc and FPDc) prolongation and clinical trial QTc prolongation. Of 20 drugs studied that exhibit clinical QTc prolongation, 17 caused APDc prolongation (16 in Cor.4U and 13 in iCell cardiomyocytes) and 16 caused FPDc prolongation (16 in Cor.4U and 10 in iCell cardiomyocytes). Of 14 drugs that cause TdP, arrhythmias occurred with 10 drugs. Lack of arrhythmic beating in iPSC-CMs for the four remaining drugs could be due to differences in relative levels of expression of individual ion channels. iPSC-CMs responded consistently to human ether-a-go-go potassium channel blocking drugs (APD prolongation and arrhythmias) and calcium channel blocking drugs (APD shortening and prevention of arrhythmias), with a more variable response to late sodium current blocking drugs. Current results confirm the potential of iPSC-CMs for proarrhythmia prediction under CiPA, where iPSC-CM results would serve as a check to ion channel and in silico modeling prediction of proarrhythmic risk. A multi-site validation study is warranted. PMID- 27701123 TI - Burn Wound Healing Activity of Lythrum salicaria L. and Hypericum scabrum L. AB - OBJECTIVE: Burns are complicated traumatic injuries caused by several physical or chemical factors. Plants with a wide range of secondary metabolites, with valuable properties like antioxidant and anti-inflammatory activities, can be a promising source of wound healing agents. MATERIALS AND METHODS: Effects of hydromethanolic extracts of Lythrum salicaria and Hypericum scabrum, individually and in combination, were assessed in second-degree burn wounds in rats in comparison to a white oleaginous base (negative control) and silver sulfadiazine (positive control). Histological assessments as well as total thiol molecules, lipid peroxidation, and total antioxidant power were evaluated in skin tissue samples. Total phenol, flavonoids, and tannins along with the antioxidant and antimicrobial activities of the extracts were also as- sessed. RESULTS: Total phenol, total flavonoid, and total tannin amounts for L. salicaria and H. scabrum were 331 +/- 3.7 and 308.1 +/- 5.2 MUg gallic acid/mg extract, 5.8 +/- 0.4 and 4.3 +/- 0.3 MUg quercetin/mg extract, and 430 +/- 2.33 and 13.4 +/- 0.5 MUg tannic acid/mg extract, respectively. H. scabrum significantly inhibited S. aureus and L. salicaria moderately suppressed Staphylococcus aureus and Candida albicans growth. Wound contraction percentage with L. salicaria and H. scabrum was 89.5 +/- 3.7 and 77.6 +/- 4.1, respectively. A well-organized epidermal layer and normal appearance in dermis layer were more observable in the L. salicaria group. Moreover, L. salicaria ointment individually displayed better influence on tissue oxidative stress parameters than H. scabrum and the negative control (P < 0.05). CONCLUSION: Results of this study clearly confirm the effectiveness of L. salicaria topical ointment as a wound healing agent, possibly due to the considerable polyphenolic content and antioxidant properties. PMID- 27701124 TI - Application of Heparinized Selective Acellular Sheepskin in Wound-healing Promotion of Deep Second-degree Burns. AB - INTRODUCTION: This study investigated the application of selective sheepskin acellular dermal matrix (ADM), combined with the anticoagulant heparin, in the wound-healing treatment of deep second-degree burns (DSDB). METHODS: A DSDB model was established, and the test animals were randomly divided into 4 groups: iodophor gauze (IG), pig ADM (PA), selective sheepskin ADM (SSA), and heparinized selective sheepskin ADM (HSSA).The microcirculation of the wound surface, pathological structures, healing rates, and fibroblast apoptosis rates were observed at different times in each group. RESULTS: At 24, 48, and 72 hours post burn, the filling degree of microcirculation in the HSSA group was higher than that in all other groups (P < 0.05). On days 14, 21, and 28 post-burn, the wound healing rates in the 3 biological-dressing groups were significantly better than the rate in the IG group (P < 0.05). On days 14 to 28 post-burn, the number of apoptotic fibroblasts in each group had increased significantly, with the number in the HSSA group on day 28 being significantly higher than that in the other groups (P < 0.05). DISCUSSION: When used in treating burn wounds, HSSA, SSA, and PA protect the cellular wound surface and provide an ideal growing environment for the fibroblasts and endothelial cells to promote wound healing and scar inhibition. CONCLUSION: The selective sheepskin ADM was successfully produced and found to exhibit better effects in protecting microcirculation and promoting wound healing compared with all other analyzed methods. PMID- 27701121 TI - From the Cover: Manganese Stimulates Mitochondrial H2O2 Production in SH-SY5Y Human Neuroblastoma Cells Over Physiologic as well as Toxicologic Range. AB - Manganese (Mn) is an abundant redox-active metal with well-characterized mitochondrial accumulation and neurotoxicity due to excessive exposures. Mn is also an essential co-factor for the mitochondrial antioxidant protein, superoxide dismutase-2 (SOD2), and the range for adequate intake established by the Institute of Medicine Food and Nutrition Board is 20% of the interim guidance value for toxicity by the Agency for Toxic Substances and Disease Registry, leaving little margin for safety. To study toxic mechanisms over this critical dose range, we treated human neuroblastoma SH-SY5Y cells with a series of MnCl2 concentrations (from 0 to 100 MUM) and measured cellular content to compare to human brain Mn content. Concentrations <=10 MUM gave cellular concentrations comparable to literature values for normal human brain, whereas concentrations >=50 MUM resulted in values comparable to brains from individuals with toxic Mn exposures. Cellular oxygen consumption rate increased as a function of Mn up to 10 MUM and decreased with Mn dose >=50 MUM. Over this range, Mn had no effect on superoxide production as measured by aconitase activity or MitoSOX but increased H2O2 production as measured by MitoPY1. Consistent with increased production of H2O2, SOD2 activity, and steady-state oxidation of total thiol increased with increasing Mn. These findings have important implications for Mn toxicity by re directing attention from superoxide anion radical to H2O2-dependent mechanisms and to investigation over the entire physiologic range to toxicologic range. Additionally, the results show that controlled Mn exposure provides a useful cell manipulation for toxicological studies of mitochondrial H2O2 signaling. PMID- 27701125 TI - The Use of Bovine Collagen-glycosaminoglycan Matrix for Atypical Lower Extremity Ulcers. AB - The primary purpose of this study was to evaluate the use of bovine collagen glycosaminoglycan matrix on atypical lower extremity ulcers. A retrospective chart review was performed on patients who underwent application of bovine collagen matrix to a lower extremity ulcer with an atypical etiology including autoimmune disease, sickle cell anemia, radiation therapy, connective tissue disease, vasculitis, or coagulopathy from January 2009 to October 2014. The following outcomes were evaluated: rate of ulcer healing and closure, number of ulcers that received a split-thickness skin graft, improvement in pain, and complications related to the ulcer. Thirty-eight patients with 71 lower extremity ulcers were analyzed. The most common ulcer etiolo- gies included rheumatoid arthritis, sickle cell anemia, and coagulopa- thy. After application of the bovine collagen matrix, 30 (42.3%) ulcers healed at a mean of 220.9 days. Of the 71 ulcers, 26 (36.6%) re- ceived a split-thickness skin graft after application of the matrix and 17 (65.4%) of those went on to complete healing. Ten patients had a local infection noted during follow-up, and 5 patients had dehiscence or dissociation of the matrix. Atypical lower extremity ulcers, such as those caused by autoimmune diseases and sickle cell anemia, proved difficult to heal. This case series shows that bovine collagen matrix can be a successful adjunctive therapy for the treatment of these challenging ulcers. PMID- 27701127 TI - Efficacy and Safety of a Novel Autologous Wound Matrix in the Management of Complicated, Chronic Wounds: A Pilot Study. AB - INTRODUCTION: The objective of this pilot study was to evaluate the efficacy and safety of a novel method using an autologous whole blood clot formed with the RedDress Wound Care System (RD1, RedDress Ltd, Israel), a provisional whole blood clot matrix used in the treatment of chronic wounds of various etiologies. METHODS AND MATERIALS: Patients were treated at the bedside with the whole blood clot matrix. Blood was withdrawn from each patient using citrate, mixed with a calcium gluconate/kaolin suspension, and injected into an RD1 clotting tray. Within 10 minutes, a clot was formed, placed upon the wound, and fixed with primary and secondary dressings. Wounds were redressed weekly with a whole blood clot matrix. Treatment was terminated when complete healing was achieved, or when the clinician determined that the wound could not further improve without additional invasive procedures. RESULTS: Seven patients with multiple and serious comorbidities and 9 chronic wounds were treated with 35 clot matrices. Complete healing was achieved in 7 of 9 wounds (78%). In 1 venous ulcer with a nonhealing fistula, 77% healing was achieved. Treatment was terminated in 1 pressure ulcer at 82% closure, because an unexpected mechanical trauma resulted in deterioration; this was the only adverse event reported, unrelated to the product. No systemic adverse events occurred. CONCLUSIONS: This pilot study demonstrates the in vitro autologous whole blood clot matrix is effective and safe for treating patients with chronic wounds of different etiologies. A larger clinical trial is needed to assess the relative success rate of the matrix in different types of wounds in a diverse population with comorbidities. PMID- 27701126 TI - Management of Open Distal Lower Extremity Wounds With Exposed Tendons Using Porcine Urinary Bladder Matrix. AB - : Open wounds of the distal third of the leg and foot with an exposed tendon present a challenge in wound management and in attaining stable, durable coverage. The mobility of the tendon often leads to chronic inflammation that impedes wound closure, while the desiccation of the exposed tendon leads to progressive tendon necrosis. For the authors' cases, the ability of extracellular matrix (ECM) products to modulate wound bed inflammation and facilitate constructive remodeling of a wound seemed a reasonable approach in treating these wounds, especially in patients who are often poor surgical candidates for more advanced reconstructive procedures. METHODS: The authors reviewed 13 patients who had open wounds of the distal third of the leg and/or foot that had associated tendon involvement in the wound (Achilles, 6; tibialis anterior, 6; and peroneal, 1). Patients' wounds were treated to total closure. The clinical course and patient management is reviewed herein. RESULTS: The authors found newer ECM products can provide a more optimal method of management of patients with exposed tendons, as compared to prolonged negative pressure wound therapy. CONCLUSION: Furthermore, the authors conclude the use of newer ECM products yields a more stable, less scarred, reconstructed wound that more closely resembles normal foot and ankle appearance compared to other more complex reconstructive operative procedures. PMID- 27701128 TI - Histogram Planimetry Method for the Measurement of Irregular Wounds. AB - INTRODUCTION: Irregularly shaped wounds or flap borders usually require specified software or devices to measure their area and follow-up wound healing. In this study, an easy way of area measurement called histogram planimetry (HP) for wounds with irregular geometric shapes is defined and compared to conventional millimetric wound measurement. MATERIALS AND METHODS: Ten irregularly bordered geometric shapes were measured by 4 different individuals working as surgical assistants using both HP and manual millimetric measurement tools. The amount of time for each wound shape calculation as well as the measurements of the wound areas were noted. All measurements were compared for each method and between each individual using the Wilcoxon signed-rank test. RESULTS: There was no statistically significant difference between 2 measurement methods by means of measured areas; however, measurement time was significantly lower when the HP method was used. There also was no significant difference between the individuals' measurements and calculation times. These results indicated that HP is useful as a conventional millimetric square wound measurement technique with significantly lower measurement times. CONCLUSION: Due to the development of photo-editor software technologies, measurements in the surgical field have become more accurate and rapid than conventional manual methods without consuming the time and energy needed for other studies. A future study including comparisons between the presented method and complex computerized measurement methods, in terms of duration and accuracy, may provide additional supportive data for the authors' method.

AB - Kaposi sarcoma (KS) is a tumor derived from endothelial cell lineage caused by Kaposi sarcoma-associated virus or human herpesvirus-8. The authors have set forth to describe a unique presentation of the classical form of KS in a homosexual individual. The authors demonstrate that a full history and physical are important in determining how to guide treatment along with ancillary tests, which can prove vital to determine management strategy. The authors then provide a brief discussion about variants of KS, biopsy techniques, and current treatment options available to patients diagnosed with this condition. The patient described is a 60-year-old male of Eastern European descent, who is immunocompetent in a monogamous homosexual relationship with a new onset and rapidly progressing skin lesion on the plantar aspect of his foot. Surgical excision of the tumor was performed and surveillance was determined to be the treatment of choice. PMID- 27701131 TI - Editorial Message: The 'New' Oblivion. PMID- 27701129 TI - Biomechanical Skin Property Evaluation for Wounds Treated With Synthetic and Biosynthetic Wound Dressings and a Newly Developed Collagen Matrix During Healing of Superficial Skin Defects in a Rat Models. AB - INTRODUCTION: There is a high prevalence of superficial wounds such as partial thickness burns. Treatment of these wounds frequently includes temporary application of wound dressings. The aim of this study was to compare a newly developed collagen matrix with commonly used temporary skin dressings for treatment of partial-thickness skin defects. MATERIALS AND METHODS: Through a skin dermatome, 42 standardized superficial skin defects were generated on the back of 28 adult male Lewis rats. The wounds were treated with a synthetic wound dressing (Suprathel, Polymedics Innovations Inc, Woodstock, GA) (n = 14), a biosynthetic skin dressing (Biobrane, Smith & Nephew, Hull, UK) (n = 14), or a newly developed bovine collagen matrix, Collagen Cell Carrier (Viscofan BioEngineering, Weinheim, Germany) (n = 14). Biomechanical properties of the skin were determined and compared every 10 days over a 3-month period of using the Cutometer MPA 580 (Courage + Khazaka Electronic GmbH, Cologne, Germany). RESULTS: As opposed to healthy skin, statistically significant differences were detected between days 10 and 30, and between days 60 and 80, for calculated elasticity (Ue), firmness of skin (R0), and overall elasticity (R8). After 3 months, no statistically significant differences in skin elasticity were detected between the different wound dressings. CONCLUSIONS: The presented results give an opportunity to compare the wound dressings used for treatment with respect to skin elasticity and reveal the potential of the bovine collagen matrix in the treatment of superficial skin defects; therefore the results facilitate further evaluation of collagen matrix in surgical applications and regenerative medicine. PMID- 27701133 TI - Harmonisation of serum dihydrotestosterone analysis: establishment of an external quality assurance program. AB - BACKGROUND: Serum dihydrotestosterone (DHT) is an important analyte for the clinical assessment of disorders of sex development. It is also reportedly a difficult analyte to measure. Currently, there are significant gaps in the standardisation of this analyte, including no external quality assurance (EQA) program available worldwide to allow for peer review performance of DHT. We therefore proposed to establish a pilot EQA program for serum DHT. METHODS: DHT was assessed in the 2015 Royal College of Pathologists of Australasia Quality Assurance Programs' Endocrine program material. The material's target (i.e. "true") values were established using a measurement procedure based on isotope dilution gas chromatography (GC) tandem mass spectrometry (MS/MS). DHT calibrator values were based on weighed values of pure DHT material (>97.5% purity) from Sigma. The allowable limits of performance (ALP) were established as +/-0.1 up to 0.5 nmol/L and +/-15% for targets >0.5 nmol/L. RESULTS: Target values for the six levels of RCPAQAP material for DHT ranged from 0.02 to 0.43 nmol/L (0.01-0.12 ng/mL). The material demonstrated linearity across the six levels. There were seven participating laboratories for this pilot study. Results of the liquid chromatography (LC) MS/MS methods were within the ALP; whereas the results from the immunoassay methods were consistently higher than the target values and outside the ALP. CONCLUSIONS: This report provides the first peer comparison of serum DHT measured by mass spectrometry (MS) and immunoassay laboratories. Establishment of this program provides one of the pillars to achieve method harmonisation. This supports accurate clinical decisions where DHT measurement is required.

AB - An automated bioreactor system for three-dimensional (3D) cultivation of facial cartilage replacement matrices (e.g. whole human auricles) with automatised medium exchange, gas flow and temperature control was developed. The measurement of O2 saturation and pH value in the medium was performed with a non-invasive optical method. The whole system can be observed via remote monitoring worldwide. First results demonstrated that the complete system remained sterile throughout a period of 42 days. Human chondrocytes migrated into the employed cartilage replacement matrix consisting of decellularised porcine nasoseptal cartilage (pNSC). Furthermore, an improved migration and new synthesis of aggrecan was detected. A first evaluation of the system was conducted by comparison of the results from laboratory analysis with computational fluid dynamics (CFD).

AB - BACKGROUND: Adolescents spend an increasing amount of their time engaged in screen using activities. The present study aimed at identifying parental factors associated with screen time among Greek adolescents. METHODS: A sample of 1141 adolescents, as well as their parents, participated in this survey. Adolescents were asked to complete a questionnaire about time spent on screen-viewing behaviors. Respectively, parents completed a questionnaire concerning family predictors. Multiple regression analysis was used to determine correlates of adolescent screen-viewing with family predictors. RESULTS: The mean screen time per weekday was 193 min. Adolescents, whose parents had received up to secondary school education, spend more time in screen-viewing compared with the other groups. Controlling adolescents' gender and age, all the family variables (perceived rules, parental modeling, parents' screen related sedentary behavior, parental concern for screen viewing, support for physical activity, parental education) were statistically significant in predicting adolescent screen time with Perceived Rules recording a higher negative beta value (beta=-0.18, p<0.00). CONCLUSION: Perceived parental screen time rules play a role in the amount of screen time among adolescents. Interventions that focus on parental limit setting development and physical activity support may be effective in decreasing screen time among youth aged 13-15 years. PMID- 27701136 TI - A pilot study of depression, stigma, and attitudes towards seeking professional psychological help among Arab adolescents. AB - The Arab region has the largest proportion of young people in the world and many of the factors that contribute to the onset of depression. Yet, very little is known about the current situation of depression and its associated stigma in this region. The purpose of this pilot study was to obtain preliminary data examining clinically significant depressive symptoms, depression stigma, and attitudes towards seeking professional help for depression among a sample of Arab adolescents from Jordan. Cross-sectional data were collected from 88 adolescents attending public schools in Jordan using self-report questionnaires that were available in, or translated into, Arabic. Among the 88 adolescents, 22% reported scores suggesting mild depression and 19% reported scores suggesting moderate depression, while 24% reported scores suggesting severe depression. The most frequently reported depressive symptoms were changes in sleep patterns (76%), changes in appetite (63%), agitation (62%), and crying (61%). The majority (73%) had moderate depression stigma, and 43% had negative attitudes towards seeking professional help. Yet, 67% believed they would find relief in psychotherapy if they ever had a serious emotional crisis. Findings suggest that the prevalence of depressive symptoms may be high among Jordanian adolescents. Further, many of these adolescents may experience depression-related stigma that affects their attitudes and willingness to seek professional help. To determine the true scope of these issues, including the prevalence of depression among Jordanian adolescents, future research should obtain data from a nationally representative sample. PMID- 27701137 TI - Oxidative stress, histopathological and electron microscopic alterations induced by dimethylnitrosamine in renal male mice and the protective effect of alpha lipoic acid. AB - BACKGROUND: Dimethylnitrosamine (DMN) is a waste product of several industrial processes. alpha-Lipoic acid (ALA) is a vitamin-like chemical also called as an antioxidant. Therefore, the study was designed to investigate the potential benefits of ALA in reducing the nephropathy of DMN in male mice. METHODS: Animals were divided into 6 groups (n=8) and received their treatment for 4 weeks as follows: groups 1-4 served as control, ALA-treatment (16.12 mg/kg), DMN low dose treatment and DMN high dose treatment, respectively. Groups 5 and 6 received ALA before DMN low dose and DMN high dose, respectively. Superoxide dismutase, catalase, glutathione peroxidase and xanthine oxidase, total antioxidant capacity, nitric oxide, lipid peroxidation as well as the levels of uric acid and creatinine were determined. The histological and ultrastructure changes of renal tissue were also evaluated. RESULTS: Treatment of the DMN mice with ALA showed a reduction in the levels of kidney nitric oxide, lipid peroxidation, as well as creatinine and uric acid levels as compared with the DMN group. The results show that ALA plays an important role in quenching the free radicals resulting from the metabolism of DMN, thereby inhibiting lipid peroxidation and protecting membrane lipids from oxidative damage and, in turn, preventing oxidative stress and apoptosis. Histopathological and ultrastructure analysis of renal tissue confirmed the oxidative stress results occurred in DMN renal mice. Concomitant administration of ALA with DMN significantly decreased all the histopathological changes induced by DMN. CONCLUSIONS: The present study elucidated the therapeutic effects of ALA administered in combination with DMN to minimize its renal toxicity. PMID- 27701138 TI - The ameliorating effect of Centella asiatica ethanolic extract on albino rats treated with isoniazid. AB - BACKGROUND: Isoniazid, also called isonicotinyl hydrazine (INH), is a commonly used drug for treating tuberculosis. The main drawback is its toxic side effects. Centella asiatica has long been used in the Ayurvedic system of medicine owing to its wide medicinal properties. This study was designed to examine the effectiveness of C. asiatica ethanolic leaf extract (CA) on INH-treated albino rats. METHODS: The adverse effects induced by INH (50 mg/kg bw) administration on haematological parameters, oxidative status (thiobarbituric acid-reactive substances, superoxide dismutase, catalase, and reduced glutathione), liver and kidney function markers, and their amelioration by various concentrations of CA (20, 40, 60, and 100 mg/kg bw) or silymarin (SIL) (50 mg/kg bw, administered before 1 h of INH treatment for 30 days to rats) were studied. Moreover, histological studies were carried out in liver and kidney tissues of rats treated with the most effective concentration to further support the possible effectiveness of CA on INH-intoxicated rats. RESULTS: All the affected parameters returned to near-normal levels, and the effective concentration of extract was found to be 100 mg/kg bw. The histology of both the liver and the kidneys subsequently supported the effectiveness of CA (100 mg/kg bw). CONCLUSIONS: Altogether, the results suggest that CA at 100 mg/kg bw can substantially reduce the toxic effects of INH. PMID- 27701139 TI - Epigenomic reprogramming in inorganic arsenic-mediated gene expression patterns during carcinogenesis. AB - Arsenic is a ubiquitous metalloid that is not mutagenic but is carcinogenic. The mechanism(s) by which arsenic causes cancer remain unknown. To date, several mechanisms have been proposed, including the arsenic-induced generation of reactive oxygen species (ROS). However, it is also becoming evident that inorganic arsenic (iAs) may exert its carcinogenic effects by changing the epigenome, and thereby modifying chromatin structure and dynamics. These epigenetic changes alter the accessibility of gene regulatory factors to DNA, resulting in specific changes in gene expression both at the levels of transcription initiation and gene splicing. In this review, we discuss recent literature reports describing epigenetic changes induced by iAs exposure and the possible epigenetic mechanisms underlying these changes. PMID- 27701140 TI - Leaves of Cordia boissieri A. DC. as a potential source of bioactive secondary metabolites for protection against metabolic syndrome-induced in rats. AB - Cordia boissieri A. DC. (Boraginaceae) is traditionally used as an herbal remedy for diabetes by Hispanic women in Southwestern USA. A recent investigation showed the significant protective effect of ethyl acetate extract against metabolic syndrome (MS). However, the corresponding active principles responsible for this effect and relations between their structure and biological actions remain unclear. Thus, ethyl acetate extract was subjected to column chromatography, which yielded seven compounds identified on the basis of spectroscopic data as rutin, hesperidin, kaempferol-3-O-beta-d-glucopyranoside, rosmarinic acid, beta sitosterol-3-O-beta-d-glucopyranoside, quercetin, and kaempferol. The isolated compounds (5 mg/kg/day) were tested in a fructose enriched-diet rat model using metformin as a standard drug. Blood samples were withdrawn for estimation of MS associated biomarkers and liver samples were subjected to histopathological and immunohistochemical examination. The isolated compounds impaired most of the changes associated with MS as evidenced by improved insulin sensitivity, glucose tolerance, kidney function, lipid profiles and reduced oxidative stress and inflammation by different degrees. It is worth noting that quercetin and kaempferol showed the most potent effect. Structure-activity relationship study revealed that the presence of 2,3-double bond in ring C and ortho-hydroxylation in ring B increases the flavonoids activity while glycosylation or methylation decreased this activity. PMID- 27701141 TI - Cytochalasin P1, a new cytochalasin from the marine-derived fungus Xylaria sp. SOF11. AB - A new cytochalasin, named cytochalasin P1 (1), together with four known analogs (2-5) was isolated from marine-derived fungus Xylaria sp. SOF11 from the South China Sea. The structure of the new compound was elucidated on the basis of MS and NMR (1H, 13C, HSQC, HMBC, and NOESY) data analyses. Compounds 1-5 were tested for their cytotoxicities against four tumor cell lines (SF-268, MCF-7, NCI-H460, and HepG-2). Compounds 1-5 showed significant cytotoxicity against two tumor cell lines MCF-7 and SF-268, with the IC50 values varying between 0.33 and 4.17 MUM. PMID- 27701142 TI - Caspase-1 from the silkworm, Bombyx mori, is involved in Bombyx mori nucleopolyhedrovirus infection. AB - Caspase-1 is one of the effector caspases in mammals that plays a central role in apoptosis. However, the lepidopteran caspase-1, especially the Bombyx mori caspase-1 (Bm-caspase-1), has not been investigated in detail. In this study, Bm caspase-1 was identified from an expressed sequence tag database in B. mori by BLAST search. The open reading frame of Bm-caspase-1 contained 879 nucleotides and encoded 293 amino acids with a predicted molecular mass of 33 kDa. Bm-caspase 1 contained two consensus amino acid motifs of caspase cleavage sites, DEGDA and TETDG. Caspase activity assays revealed significant proteolytic activity of the Ac-DEVD-pNA substrate. Bm-caspase-1 can be detected in all tissues and developmental stages by a semi quantitative polymerase chain reaction assay. More importantly, the expression level of Bm-caspase-1 is increased upon baculovirus infection and up-regulated in BmNPV-resistant silkworms. Taken together, these results indicate that Bm-caspase-1 plays an important role during baculovirus infection. PMID- 27701143 TI - Ultrafast domain wall dynamics in magnetic nanotubes and nanowires. AB - The dynamic properties of magnetic domain walls in nanotubes and in cylindrical nanowires can be significantly different from the well known domain wall dynamics in thin films and in flat thin strips. The main differences are the occurrence of chiral symmetry breaking and, perhaps more importantly, the possibility to obtain magnetic domain walls that are stable against the usual Walker breakdown. This stability enables the magnetic field-driven propagation of the domain walls in nanotubes and nanocylinders at constant velocities which are significantly higher than the usual propagation speeds of the domain walls. Simulations predict that the ultrafast motion of magnetic domain walls at velocities in a range above 1000 m s-1 can lead to the spontaneous excitation of spin waves in a process that is the magnetic analog of the Cherenkov effect. In the case of solid cylindrical wires, the domain wall can contain a micromagnetic point singularity. We discuss the current knowledge on the ultrafast dynamics of such Bloch points, which remains still largely unexplored. PMID- 27701144 TI - Thermal transport phenomena in nanoparticle suspensions. AB - Nanoparticle suspensions in liquids have received great attention, as they may offer an approach to enhance thermophysical properties of base fluids. A good variety of applications in engineering and biomedicine has been investigated with the aim of exploiting the above potential. However, the multiscale nature of nanosuspensions raises several issues in defining a comprehensive modelling framework, incorporating relevant molecular details and much larger scale phenomena, such as particle aggregation and their dynamics. The objectives of the present topical review is to report and discuss the main heat and mass transport phenomena ruling macroscopic behaviour of nanosuspensions, arising from molecular details. Relevant experimental results are included and properly put in the context of recent observations and theoretical studies, which solved long standing debates about thermophysical properties enhancement. Major transport phenomena are discussed and in-depth analysis is carried out for highlighting the role of geometrical (nanoparticle shape, size, aggregation, concentration), chemical (pH, surfactants, functionalization) and physical parameters (temperature, density). We finally overview several computational techniques available at different scales with the aim of drawing the attention on the need for truly multiscale predictive models. This may help the development of next generation nanoparticle suspensions and their rational use in thermal applications. PMID- 27701145 TI - Decreased somatic hypermutation induces an impaired peripheral B cell tolerance checkpoint. AB - Patients with mutations in AICDA, which encodes activation-induced cytidine deaminase (AID), display an impaired peripheral B cell tolerance. AID mediates class-switch recombination (CSR) and somatic hypermutation (SHM) in B cells, but the mechanism by which AID prevents the accumulation of autoreactive B cells in blood is unclear. Here, we analyzed B cell tolerance in AID-deficient patients, patients with autosomal dominant AID mutations (AD-AID), asymptomatic AICDA heterozygotes (AID+/-), and patients with uracil N-glycosylase (UNG) deficiency, which impairs CSR but not SHM. The low frequency of autoreactive mature naive B cells in UNG-deficient patients resembled that of healthy subjects, revealing that impaired CSR does not interfere with the peripheral B cell tolerance checkpoint. In contrast, we observed decreased frequencies of SHM in memory B cells from AD-AID patients and AID+/- subjects, who were unable to prevent the accumulation of autoreactive mature naive B cells. In addition, the individuals with AICDA mutations, but not UNG-deficient patients, displayed Tregs with defective suppressive capacity that correlated with increases in circulating T follicular helper cells and enhanced cytokine production. We conclude that SHM, but not CSR, regulates peripheral B cell tolerance through the production of mutated antibodies that clear antigens and prevent sustained interleukin secretions that interfere with Treg function. PMID- 27701146 TI - Adipocyte-specific deletion of Ip6k1 reduces diet-induced obesity by enhancing AMPK-mediated thermogenesis. AB - Enhancing energy expenditure (EE) is an attractive strategy to combat obesity and diabetes. Global deletion of Ip6k1 protects mice from diet-induced obesity (DIO) and insulin resistance, but the tissue-specific mechanism by which IP6K1 regulates body weight is unknown. Here, we have demonstrated that IP6K1 regulates fat accumulation by modulating AMPK-mediated adipocyte energy metabolism. Cold exposure led to downregulation of Ip6k1 in murine inguinal and retroperitoneal white adipose tissue (IWAT and RWAT) depots. Adipocyte-specific deletion of Ip6k1 (AdKO) enhanced thermogenic EE, which protected mice from high-fat diet-induced weight gain at ambient temperature (23 degrees C), but not at thermoneutral temperature (30 degrees C). AdKO-induced increases in thermogenesis also protected mice from cold-induced decreases in body temperature. UCP1, PGC1alpha, and other markers of browning and thermogenesis were elevated in IWAT and RWAT of AdKO mice. Cold-induced activation of sympathetic signaling was unaltered, whereas AMPK was enhanced, in AdKO IWAT. Moreover, beige adipocytes from AdKO IWAT displayed enhanced browning, which was diminished by AMPK depletion. Furthermore, we determined that IP6 and IP6K1 differentially regulate upstream kinase-mediated AMPK stimulatory phosphorylation in vitro. Finally, treating mildly obese mice with the IP6K inhibitor TNP enhanced thermogenesis and inhibited progression of DIO. Thus, IP6K1 regulates energy metabolism via a mechanism that could potentially be targeted in obesity. PMID- 27701150 TI - Nanoparticle Technologies in the Spinal Cord. AB - Nanoparticles are increasingly being studied within experimental models of spinal cord injury (SCI). They are used to image cells and tissue, move cells to specific regions of the spinal cord, and deliver therapeutic agents locally. The focus of this article is to provide a brief overview of the different types of nanoparticles being studied for spinal cord applications and present data showing the capability of nanoparticles to deliver the chondroitinase ABC (chABC) enzyme locally following acute SCI in rats. Nanoparticles releasing chABC helped promote axonal regeneration following injury, and the nanoparticles also protected the enzyme from rapid degradation. In summary, nanoparticles are viable materials for diagnostic or therapeutic applications within experimental models of SCI and have potential for future clinical use. PMID- 27701148 TI - Inhibition of CDK4/6 protects against radiation-induced intestinal injury in mice. AB - Radiotherapy causes dose-limiting toxicity and long-term complications in rapidly renewing tissues, including the gastrointestinal tract. Currently, there is no FDA-approved agent for the prevention or treatment of radiation-induced intestinal injury. In this study, we have shown that PD 0332991 (PD), an FDA approved selective inhibitor of cyclin-dependent kinase 4/6 (CDK4/6), prevents radiation-induced lethal intestinal injury in mice. Treating mice with PD or a structurally distinct CDK4/6 inhibitor prior to radiation blocked proliferation and crypt apoptosis and improved crypt regeneration. PD treatment also enhanced LGR5+ stem cell survival and regeneration after radiation. PD was an on-target inhibitor of RB phosphorylation and blocked G1/S transition in the intestinal crypts. PD treatment strongly but reversibly inhibited radiation-induced p53 activation, which blocked p53-upregulated modulator of apoptosis-dependent (PUMA dependent) apoptosis without affecting p21-dependent suppression of DNA damage accumulation, with a repair bias toward nonhomologous end joining. Further, deletion of PUMA synergized with PD treatment for even greater intestinal radioprotection. Our results demonstrate that the cell cycle critically regulates the DNA damage response and survival of intestinal stem cells and support the concept that pharmacological quiescence is a potentially highly effective and selective strategy for intestinal radioprotection. PMID- 27701147 TI - Cancer-associated fibroblast-derived annexin A6+ extracellular vesicles support pancreatic cancer aggressiveness. AB - The intratumoral microenvironment, or stroma, is of major importance in the pathobiology of pancreatic ductal adenocarcinoma (PDA), and specific conditions in the stroma may promote increased cancer aggressiveness. We hypothesized that this heterogeneous and evolving compartment drastically influences tumor cell abilities, which in turn influences PDA aggressiveness through crosstalk that is mediated by extracellular vesicles (EVs). Here, we have analyzed the PDA proteomic stromal signature and identified a contribution of the annexin A6/LDL receptor-related protein 1/thrombospondin 1 (ANXA6/LRP1/TSP1) complex in tumor cell crosstalk. Formation of the ANXA6/LRP1/TSP1 complex was restricted to cancer associated fibroblasts (CAFs) and required physiopathologic culture conditions that improved tumor cell survival and migration. Increased PDA aggressiveness was dependent on tumor cell-mediated uptake of CAF-derived ANXA6+ EVs carrying the ANXA6/LRP1/TSP1 complex. Depletion of ANXA6 in CAFs impaired complex formation and subsequently impaired PDA and metastasis occurrence, while injection of CAF derived ANXA6+ EVs enhanced tumorigenesis. We found that the presence of ANXA6+ EVs in serum was restricted to PDA patients and represents a potential biomarker for PDA grade. These findings suggest that CAF-tumor cell crosstalk supported by ANXA6+ EVs is predictive of PDA aggressiveness, highlighting a therapeutic target and potential biomarker for PDA. PMID- 27701151 TI - The Body Acoustic: Ultrasonic Neuromodulation for Translational Medicine. AB - For the greater part of the last century, ultrasound (US) has seen widespread use in applications ranging from materials science to medicine. The history of US in medicine has also seen promising success in clinical diagnostics and regenerative medicine. Recent studies have shown that US is able to manipulate the nervous system, leading toward potential treatment for various neuropathological conditions, a phenomenon known as ultrasonic neuromodulation (NM). Ultrasonic NM is a promising alternative to pharmaceuticals and surgery, due to high spatiotemporal resolution combined with the potentially noninvasive means of application. Current advances have made progress in establishing effective dosage limits, waveform parameters, and stimulus regimes in order to achieve desired effects in a variety of tissue and cell types. However, to date there has been limited systematic analysis of the complex variables involved in creating a therapeutic US stimulation regime specifically tailored to the nervous system. Without a fundamental understanding of the effects of US on neural tissue, including the surrounding bone, musculature, and vasculature, the safety and efficacy of US as an NM tool is yet to be determined. Advances in imaging technology and focusing hardware highlight new avenues for potential clinical applications for therapeutic ultrasonic stimulation. US may be an alternative to electrical and magnetic means of NM for targets in the central nervous system as well as in the peripheral and autonomic nervous systems. This review provides a historical perspective on the past, present, and future of US as a translational therapeutic. PMID- 27701149 TI - MST1-dependent vesicle trafficking regulates neutrophil transmigration through the vascular basement membrane. AB - Neutrophils need to penetrate the perivascular basement membrane for successful extravasation into inflamed tissue, but this process is incompletely understood. Recent findings have associated mammalian sterile 20-like kinase 1 (MST1) loss of function with a human primary immunodeficiency disorder, suggesting that MST1 may be involved in immune cell migration. Here, we have shown that MST1 is a critical regulator of neutrophil extravasation during inflammation. Mst1-deficient (Mst1-/ ) neutrophils were unable to migrate into inflamed murine cremaster muscle venules, instead persisting between the endothelium and the basement membrane. Mst1-/- neutrophils also failed to extravasate from gastric submucosal vessels in a murine model of Helicobacter pylori infection. Mechanistically, we observed defective translocation of VLA-3, VLA-6, and neutrophil elastase from intracellular vesicles to the surface of Mst1-/- neutrophils, indicating that MST1 is required for this crucial step in neutrophil transmigration. Furthermore, we found that MST1 associates with the Rab27 effector protein synaptotagmin-like protein 1 (JFC1, encoded by Sytl1 in mice), but not Munc13-4, thereby regulating the trafficking of Rab27-positive vesicles to the cellular membrane. Together, these findings highlight a role for MST1 in vesicle trafficking and extravasation in neutrophils, providing an additional mechanistic explanation for the severe immune defect observed in patients with MST1 deficiency. PMID- 27701154 TI - Cytological Characteristics of Endometrial Phasing Using the Specimens Prepared with the Liquid-Based Procedure: Comparison with the Conventional Procedure. AB - OBJECTIVE: To evaluate whether or not the liquid-based procedure (LBP) for endometrial cytology is as worthwhile for endometrial phasing as conventional slides. MATERIALS AND METHODS: The subjects were 81 women who underwent endometrial cytology and were defined as negative. The specimens obtained by either Endocyte(r) or Masubuchi aspiration tube(r) were processed first with the conventional procedure and then with LBP using TACASTM. RESULTS: (1) The number of subjects diagnosed by the conventional method as having proliferative, mid-, middle-secretory and late-secretory and atrophic phases was 40, 11, 10, 0 and 20, respectively. The rate of agreement with those using LBP was 87.7%. (2) Incidences of large clusters, ductal clusters, palisade arrangement, uneven staining and dirty mucous background detected were significantly higher with the conventional method, whereas with LBP clean background, inconspicuous bonding of cells, scattered solitary glandular cells, clear well-stained cytoplasm and cell compactness were higher. (3) Especially in the proliferative phase, clusters tended to be smaller and lose their architectural structures, and scattered solitary columnar cells were present. (4) Cells in the mid-phase tended to have loose contact and to mimic other phases. CONCLUSIONS: Cytodiagnosis of endometrial phasing prepared with LBP is feasible to perform when some modifications are implemented. PMID- 27701153 TI - Electrospun Fibers for Drug Delivery after Spinal Cord Injury and the Effects of Drug Incorporation on Fiber Properties. AB - There is currently no cure for individuals with spinal cord injury (SCI). While many promising approaches are being tested in clinical trials, the complexity of SCI limits several of these approaches from aiding complete functional recovery. Several different categories of biomaterials are investigated for their ability to guide axonal regeneration, to deliver proteins or small molecules locally, or to improve the viability of transplanted stem cells. The purpose of this study is to provide a brief overview of SCI, present the different categories of biomaterial scaffolds that direct and guide axonal regeneration, and then focus specifically on electrospun fiber guidance scaffolds. Much like other polymer guidance approaches, electrospun fibers can retain and deliver therapeutic drugs. The experimental section presents new data showing the incorporation of two therapeutic drugs into electrospun poly-L-lactic acid fibers. Two different concentrations of either riluzole or neurotrophin-3 were loaded into the electrospun fibers to examine the effect of drug concentration on the physical characteristics of the fibers (fiber alignment and fiber diameter). Overall, the drugs were successfully incorporated into the fibers and the release was related to the loading concentration. The fiber diameter decreased with the inclusion of the drug, and the decreased diameter was correlated with a decrease in fiber alignment. Subsequently, the study includes considerations for successful incorporation of a therapeutic drug without changing the physical properties of the fibers. PMID- 27701155 TI - Long-Term Follow-Up Is Essential to Assess Outcome of Gastric Banding in Morbidly Obese Adolescents: A Retrospective Analysis. AB - BACKGROUND: Adolescent obesity is rapidly becoming more prevalent and is associated with chronic health conditions and psychosocial morbidity. Lifestyle intervention is often ineffective in morbidly obese adolescents, and bariatric surgery is gradually becoming an accepted treatment. However, little is known about long-term results. METHODS: Hospital charts of patients who had undergone gastric banding more than 5 years ago at an age of 18 years or younger, were retrospectively analyzed. Weight loss, complications, reoperations, and comorbidity reduction were assessed as well as health status, food behavior, and personality. RESULTS: BMI loss in 10 adolescents was 10.7 kg/m2 (-0.9 to 12.9 kg/m2) after a median follow-up of 64 months (52-84 months); the major part of weight loss occurred after the first year. In 4 patients the gastric band was removed after 3.5-5.5 years. Two out of 3 patients effectively lost weight after conversion to a bypass type procedure. One patient is maintaining a stable healthy weight after band removal. CONCLUSIONS: Laparoscopic adjustable gastric banding in morbidly obese adolescents had a failure rate of 40%, but was a successful therapy in the other 60% without major adverse events. Follow-up longer than 36 months was crucial for optimal evaluation of weight loss and reoperation rate. PMID- 27701152 TI - Tissue Engineering Approaches to Modulate the Inflammatory Milieu following Spinal Cord Injury. AB - Tissue engineering strategies have shown promise in promoting healing and regeneration after spinal cord injury (SCI); however, these strategies are limited by inflammation and the immune response. Infiltration of cells of the innate and adaptive immune responses and the inflammation that follows cause secondary damage adjacent to the injury, increased scarring, and a potently inhibitory environment for the regeneration of damaged neurons. While the inflammation that ensues is typically associated with limited regeneration, the immune response is a crucial element in the closing of the blood-brain barrier, minimizing the spread of injury, and initiating healing. This review summarizes the strategies that have been developed to modulate the immune response towards an anti-inflammatory environment that is permissive to the regeneration of neurons, glia, and parenchyma. We focus on the use of biomaterials, biologically active molecules, gene therapy, nanoparticles, and stem cells to modulate the immune response, and illustrate concepts for future therapies. Current clinical treatments for SCI are limited to systemic hypothermia or methylprednisolone, which both act by systemically mitigating the effects of immune response but have marginal efficacy. Herein, we discuss emerging research strategies to further enhance these clinical treatments by directly targeting specific aspects of the immune response. PMID- 27701156 TI - Improving Peripheral and Central Vascular Adjustments during Exercise through a Training Program in Adolescents with Obesity. AB - OBJECTIVE: The effects of a training program (TP) on muscle microvascularization during exercise remained to be explored in adolescents with obesity. We hypothesized that a TP would lead to better microvascular adaptations to exercise in skeletal muscle. METHODS: 15 inactive adolescents followed a 12-week TP where both peripheral (muscular microvascularization) and central (cardiac) adaptations to exercise (40 min exercise set at 70% VO2peak) were assessed before and after intervention. Microvascular adaptations were evaluated in the Musculus vastus lateralis with near-infrared spectroscopy, by measurement of muscular blood volume (IR-BV) and tissue oxygen saturation (IR-SO2). Central adaptations were evaluated using thoracic impedance. RESULTS: The TP favored lower BMI (p < 0.001), lower total and abdominal fat (p < 0.001), and a trend for the decrease in insulin resistance index (p = 0.07). VO2peak relative to weight (p = 0.008) and maximum power output increased (p = 0.0003). A smaller initial drop in IR-BV and IR-SO2 (p < 0.001), a prompter return of these parameters to their base values, and a higher IR-BV and IR-SO2 all times taken together (p < 0.001) were observed after completing the TP. Concerning central adaptation, cardiac output decreased (p < 0.001). CONCLUSION: We demonstrate for the first time by noninvasive techniques that a training program induces peripheral and central vascular adaptations to exercise in adolescents with obesity. PMID- 27701158 TI - Acquired FVIII and FIX Inhibitors after Pregnancy: A Case Report. AB - Acquired hemophilia is a relatively rare clinical presentation, and most cases present with acquired FVIII inhibitor. The co-occurrence of inhibitors to multiple coagulation factors is uncommon. These autoantibodies may induce spontaneous life-threatening bleeding in patients who have had no previous bleeding disorder. Herein, we present a patient with postpartum acquired FVIII and FIX inhibitors who developed intramuscular hematoma and hemothorax during follow-up. She was then treated with activated prothrombin complex concentrate and methylprednisolone. PMID- 27701157 TI - Truncating Wilms Tumor Suppressor Gene 1 Mutation in an XX Female with Adult Onset Focal Segmental Glomerulosclerosis and Streak Ovaries: A Case Report. AB - About 30% of children with nephrotic syndrome (NS) have inherited forms. Among them, mutations in Wilms tumor suppressor gene 1 (WT1) are a well characterized cause associated with steroid-resistant NS, Wilms tumor, and urogenital malformation in males. However, the role of WT1 mutations in adult-onset focal segmental glomerulosclerosis (FSGS) is unclear. We report the case of a 38-year old female with FSGS. She had been diagnosed with streak ovaries during diagnostic workup for infertility. Mutational analysis identified the heterozygous mutation c.1372C>T (p.Arg458*) in WT1 and the heterozygous non neutral polymorphism c.868G>A (p.Arg229Gln) in NPHS2. Chromosomal analysis revealed a normal 46,XX female karyotype. Our case highlights that WT1 mutations should be considered in XX females with adult-onset FSGS, especially if urogenital abnormalities are present. PMID- 27701159 TI - The Clinical Outcomes after Total Pancreatectomy. AB - BACKGROUND: Total pancreatectomy (TP) is not more beneficial than less aggressive resection techniques for the treatment of pancreatic neoplasms and is associated with high morbidity and mortality. However, with advances in surgical techniques and glycemic monitoring, and the development of synthetic insulin and pancreatic enzymes for postoperative treatment, TP has been increasingly indicated. This is a review of the recent literature reporting the clinical outcomes after TP. METHODS: We reviewed the publications reporting the use of TP starting 2007. The clinicophysiological and survival data were analyzed. RESULTS: Few studies evaluated the differences in clinical outcomes between TP and pancreaticoduodenectomy (PD) with inconsistent results. It was reported that while the perioperative morbidity did not decrease, the mortality decreased compared to previous literature. All patients who underwent TP required insulin and high dose of pancreatic enzyme supplements. The 5-year survival rates after TP and PD for pancreatic cancer were similar. CONCLUSION: The perioperative mortality decreased in patients who underwent TP with advances in the operative procedures and perioperative care. The long-term survival rates were similar for TP and PD. Therefore, treating pancreatic neoplasms using TP is feasible. Patients undergoing TP should receive adequate treatment with synthetic insulin and pancreatic enzyme supplements. PMID- 27701160 TI - Cognitive Impairment Is Associated with a Low Omega-3 Index in the Elderly: Results from the KORA-Age Study. AB - BACKGROUND: Omega-3 polyunsaturated fatty acids (PUFA) may affect the risk of cognitive decline in older adults. METHODS: Cross-sectional analysis was conducted among 720 (50.4% women) participants aged 68-92 years (mean age: 77.6, SD +/-6.2) of the population-based KORA-Age study. Eicosapentaenoic acid and docosahexaenoic acid (omega-3 index) were measured in erythrocytes as a percentage of total fatty acids. The categories low (<5.7), intermediate (5.7 6.8), and high (>6.8) levels of the omega-3 index were built using tertiles. The association between cognitive status and omega-3 levels was assessed by logistic regression analyses with adjustments for important concurrent risk factors of cognitive decline. RESULTS: In the sex- and age-adjusted model (model 1), subjects with a low omega-3 index were at a significantly higher risk for cognitive impairment (OR: 1.77, 95% CI: 1.15-2.73, p = 0.009). This association remained stable after further adjusting for educational level (model 2; OR: 1.75, 95% CI: 1.13-2.71, p = 0.01) and metabolic risk factors (model 3; OR: 1.77, 95% CI: 1.14-2.75, p = 0.01). After further controlling for affective disorders (model 4), the association did not attenuate (OR: 1.77, 95% CI: 1.14-2.76, p = 0.01). CONCLUSION: A robust association was found between low omega-3 levels and cognitive impairment in an elderly population. Further research is needed to understand the link between omega-3 PUFA and cognitive functioning. PMID- 27701161 TI - Bioelectric Medicine and Devices for the Treatment of Spinal Cord Injury. AB - Recovery of motor control is paramount for patients living with paralysis following spinal cord injury (SCI). While a cure or regenerative intervention remains on the horizon for the treatment of SCI, a number of neuroprosthetic devices have been employed to treat and mitigate the symptoms of paralysis associated with injuries to the spinal column and associated comorbidities. The recent success of epidural stimulation to restore voluntary motor function in the lower limbs of a small cohort of patients has breathed new life into the promise of electric-based medicine. Recently, a number of new organic and inorganic electronic devices have been developed for brain-computer interfaces to bypass the injury, for neurorehabilitation, bladder and bowel control, and the restoration of motor or sensory control. Herein, we discuss the recent advances in neuroprosthetic devices for treating SCI and highlight future design needs for closed-loop device systems. PMID- 27701162 TI - Injectable Hydrogels for Spinal Cord Repair: A Focus on Swelling and Intraspinal Pressure. AB - Spinal cord injury (SCI) is a devastating condition that leaves patients with limited motor and sensory function at and below the injury site, with little to no hope of a meaningful recovery. Because of their ability to mimic multiple features of central nervous system (CNS) tissues, injectable hydrogels are being developed that can participate as therapeutic agents in reducing secondary injury and in the regeneration of spinal cord tissue. Injectable biomaterials can provide a supportive substrate for tissue regeneration, deliver therapeutic factors, and regulate local tissue physiology. Recent reports of increasing intraspinal pressure after SCI suggest that this physiological change can contribute to injury expansion, also known as secondary injury. Hydrogels contain high water content similar to native tissue, and many hydrogels absorb water and swell after formation. In the case of injectable hydrogels for the spinal cord, this process often occurs in or around the spinal cord tissue, and thus may affect intraspinal pressure. In the future, predictable swelling properties of hydrogels may be leveraged to control intraspinal pressure after injury. Here, we review the physiology of SCI, with special attention to the current clinical and experimental literature, underscoring the importance of controlling intraspinal pressure after SCI. We then discuss how hydrogel fabrication, injection, and swelling can impact intraspinal pressure in the context of developing injectable biomaterials for SCI treatment. PMID- 27701164 TI - Out-Patient Management of Mild or Uncomplicated Diverticulitis: A Systematic Review. AB - BACKGROUND: Management of diverticular disease has undergone a paradigm shift, with movement towards a less invasive management strategy. In keeping with this, outpatient management of uncomplicated diverticulitis (UD) has been advocated in several studies, but concerns still remain regarding the safety of this practice. AIM: To assess outcomes of out-patient management of acute UD. METHODS: A comprehensive search for published studies using the search terms 'uncomplicated diverticulitis', 'mild diverticulitis' and 'out-patient' was performed. The primary outcomes were failure of medical treatment. Secondary outcomes were recurrence rate at follow up and medical cost savings. RESULTS: The search yielded 192 publications. Of these, 10 studies met the inclusion criteria including 1 randomized controlled trial, 6 clinical controlled trials and 3 case series. There was no difference in failure rates of medical treatment (6.5 vs. 4.6%, p = 0.32) or in recurrence rates (13.0 vs. 12.1%, p = 0.81) between those receiving ambulatory care and in-patient care for UD. Ambulatory treatment is associated with an estimated daily cost savings of between 600 and 1,900 euros per patient treated. Meta-analysis of data was not possible due to heterogeneity in study designs and inclusion criteria. CONCLUSION: Ambulatory management of acute UD is reasonable in selected patients. PMID- 27701163 TI - White Matter Changes May Precede Gray Matter Loss in Elderly with Subjective Memory Impairment. AB - BACKGROUND/AIMS: A limited number of studies addressed MRI-based neurodegenerative changes in subjective memory impairment (SMI). We investigated changes in white matter (WM) microstructures as well as gray matter (GM) macrostructures in subjects with SMI of high and low risk for progression. METHODS: A modeling scale (score range, 0-6) developed for prediction of SMI progression was used to divide SMI subjects (n = 46) into two groups: a high risk of progression (score >=3; n = 19) and a low risk of progression (score <=2; n = 27). Cross-sectional comparisons were performed using a region-of-interest-based diffusion tensor imaging (DTI) analysis, cortical thickness analysis, and hippocampal volumetry. RESULTS: The high-risk group had more microstructural disruption shown by lower fractional anisotropy in the hippocampus, parahippocampal gyrus, supramarginal gyrus, and parts of frontotemporal lobes. On the other hand, GM macrostructural changes did not differ between the groups and were not associated with modeling scale scores. CONCLUSION: SMI subjects with a high risk of progression had more WM microstructural disruption than those with a low risk, and the changes were not explained by GM atrophy. Our findings suggest that the degree of microstructural alterations in SMI may be distinctive according to the risk factors and may precede GM atrophy. PMID- 27701165 TI - Lung Ultrasound Pattern Is Normal during the Last Gestational Weeks: An Observational Pilot Study. AB - BACKGROUND/AIMS: The normal lung ultrasound (US) pattern during a regular pregnancy has not been evaluated extensively in the current literature. Pregnancy related changes in the respiratory tract affect maternal predisposition to several respiratory complications; consequently, it is important to differentiate between a physiologic pattern during pregnancy and a pathologic lung pattern, due to respiratory failure. The goal of our study was to assess the normal US lung pattern in women without known comorbidities in the last weeks of pregnancy. METHODS: We conducted a prospective cross-sectional observational pilot study. Chest wall was examined in 8 areas, 1 scan for each area with women in supine position. RESULTS: One hundred fifty parturients were enrolled during the 36th 38th gestational weeks. None of the participants showed pleural effusion, pneumothorax or lung consolidation. None presented an interstitial syndrome US pattern. One hundred thirteen participants out of 150 (75%) showed A-lines in all the regions. The remaining 25% showed 1 or 2 B-lines in at least 3 regions. Only 2 participants showed 2 positive regions also. CONCLUSIONS: We found that, in the majority of the women examined, the lung US pattern matches the physiological pattern in non-pregnant patients. Lung US assessment is a feasible and a helpful diagnostic tool during pregnancy. PMID- 27701166 TI - Biomaterial Strategies for Delivering Stem Cells as a Treatment for Spinal Cord Injury. AB - Ongoing clinical trials are evaluating the use of stem cells as a way to treat traumatic spinal cord injury (SCI). However, the inhibitory environment present in the injured spinal cord makes it challenging to achieve the survival of these cells along with desired differentiation into the appropriate phenotypes necessary to regain function. Transplanting stem cells along with an instructive biomaterial scaffold can increase cell survival and improve differentiation efficiency. This study reviews the literature discussing different types of instructive biomaterial scaffolds developed for transplanting stem cells into the injured spinal cord. We have chosen to focus specifically on biomaterial scaffolds that direct the differentiation of neural stem cells and pluripotent stem cells since they offer the most promise for producing the cell phenotypes that could restore function after SCI. In terms of biomaterial scaffolds, this article reviews the literature associated with using hydrogels made from natural biomaterials and electrospun scaffolds for differentiating stem cells into neural phenotypes. It then presents new data showing how these different types of scaffolds can be combined for neural tissue engineering applications and provides directions for future studies. PMID- 27701168 TI - Serotonin as a Differentiation Signal. PMID- 27701167 TI - Metabolic and Hormonal Determinants of Glomerular Filtration Rate and Renal Hemodynamics in Severely Obese Individuals. AB - OBJECTIVE: Renal function is often compromised in severe obesity. A true measurement of glomerular filtration rate (GFR) is unusual, and how estimation formulae (EstForm) perform in such individuals is unclear. We characterized renal function and hemodynamics in severely obese individuals, assessing the reliability of EstForm. METHODS: We measured GFR (mGFR) by iohexol plasma clearance, renal plasma flow (RPF) by 123I-ortho-iodo-hippurate, basal and stimulated vascular renal indices, endothelium-dependent and -independent vasodilation using flow-mediated dilation (FMD) as well as metabolic and hormonal profile in morbid, otherwise healthy, obese subjects. RESULTS: Compared with mGFR, the better performing EstForm was CKD-EPI (5.3 ml/min/1.73 m2 bias by Bland Altman analysis). mGFR was directly related with RPF, total and incremental glucose AUC, and inversely with PTH and h8 cortisol. Patients with mGFR below the median shown significantly higher PTH and lower vitamin D3. Basal or dynamic renal resistive index, FMD, pulse wave velocity were not related with mGFR. In an adjusted regression model, renal diameter and plasma flow remained related with mGFR (R2 = 0.67), accounting for 15% and 21% of mGFR variance, respectively. CONCLUSIONS: CKD-EPI formula should be preferred in morbid obesity; glucose increments during oral glucose tolerance test correlate with hyperfiltration; RPF and diameter are independent determinants of mGFR; slightly high PTH values, frequent in obesity, might influence mGFR. PMID- 27701169 TI - Limited Time from the Diabetes Patients' Perspective: Need for Conversation with the Eye Specialist. AB - PURPOSE: Facing the lack of time, busy retina consultants should be aware of how the patients would prefer that time is spent and whether they wish the specialist to talk more at the expense of other medical activities. METHODS: 810 persons with diabetes were asked to divide the time of 10 min between examination, consultation and treatment when envisioning a real-life scenario of diabetic retinopathy (NCT02311504). RESULTS: With the increasing duration of diabetes, patients wanted significantly more time for diagnostics (p = 0.028), while age was found to be associated with less time for treatment (p = 0.009). Female subjects tended to prefer only little more time for talking (p = 0.051) in comparison with males, who slightly favored therapy (p = 0.025). CONCLUSIONS: The large majority recognized the need for diagnostics in their allocation of time. If individual patients are confronted with the health care perspective of time constraints, this might improve the understanding of prioritization. PMID- 27701171 TI - Preface. PMID- 27701170 TI - Pre-Stroke Use of Beta-Blockers Does Not Lower Post-Stroke Infection Rate: An Exploratory Analysis of the Preventive Antibiotics in Stroke Study. AB - BACKGROUND: Stroke-associated infections occur frequently and are associated with unfavorable outcome. Previous cohort studies suggest a protective effect of beta blockers (BBs) against infections. A sympathetic drive may increase immune suppression and infections. AIM: This study is aimed at investigating the association between BB treatment at baseline and post-stroke infection in the Preventive Antibiotics in Stroke Study (PASS), a prospective clinical trial. METHODS: We performed an exploratory analysis in PASS, 2,538 patients with acute phase of stroke (24 h after onset) were randomized to ceftriaxone (intravenous, 2 g per day for 4 days) in addition to stroke unit care, or standard stroke unit care without preventive antibiotic treatment. All clinical data, including use of BBs, was prospectively collected. Infection was diagnosed by the treating physician, and independently by an expert panel blinded for all other data. Multivariable analysis was performed to investigate the relation between BB treatment and infection rate. RESULTS: Infection, as defined by the physician, occurred in 348 of 2,538 patients (14%). Multivariable analysis showed that the use of BBs at baseline was associated with the development of infection during clinical course (adjusted OR (aOR) 1.61, 95% CI 1.19-2.18; p < 0.01). BB use at baseline was also associated with the development of pneumonia (aOR 1.56, 95% CI 1.05-2.30; p = 0.03). Baseline BB use was not associated with mortality (aOR 1.14, 95% CI 0.84-1.53; p = 0.41) or unfavorable outcome at 3 months (aOR 1.10, 95% CI 0.89-1.35; p = 0.39). CONCLUSIONS: Patients treated with BBs prior to stroke have a higher rate of infection and pneumonia. PMID- 27701172 TI - Engineering Biomaterials to Influence Oligodendroglial Growth, Maturation, and Myelin Production. AB - Millions of people suffer from damage or disease to the nervous system that results in a loss of myelin, such as through a spinal cord injury or multiple sclerosis. Diminished myelin levels lead to further cell death in which unmyelinated neurons die. In the central nervous system, a loss of myelin is especially detrimental because of its poor ability to regenerate. Cell therapies such as stem or precursor cell injection have been investigated as stem cells are able to grow and differentiate into the damaged cells; however, stem cell injection alone has been unsuccessful in many areas of neural regeneration. Therefore, researchers have begun exploring combined therapies with biomaterials that promote cell growth and differentiation while localizing cells in the injured area. The regrowth of myelinating oligodendrocytes from neural stem cells through a biomaterials approach may prove to be a beneficial strategy following the onset of demyelination. This article reviews recent advancements in biomaterial strategies for the differentiation of neural stem cells into oligodendrocytes, and presents new data indicating appropriate properties for oligodendrocyte precursor cell growth. In some cases, an increase in oligodendrocyte differentiation alongside neurons is further highlighted for functional improvements where the biomaterial was then tested for increased myelination both in vitro and in vivo. PMID- 27701173 TI - Inhibitory Control and Hedonic Response towards Food Interactively Predict Success in a Weight Loss Programme for Adults with Obesity. AB - OBJECTIVE: Low inhibitory control and strong hedonic response towards food are considered to contribute to overeating and obesity. Based on previous research, the present study aimed at examining the potentially crucial interplay between these two factors in terms of long-term weight loss in people with obesity. METHODS: BMI, inhibitory control towards food, and food liking were assessed in obese adults prior to a weight reduction programme (OPTIFAST(r) 52). After the weight reduction phase (week 13) and the weight loss maintenance phase (week 52), participants' BMI was re-assessed. RESULTS: Baseline BMI, inhibitory control and food liking alone did not predict weight loss. As hypothesised, however, inhibitory control and food liking interactively predicted weight loss from baseline to week 13 and to week 52 (albeit the latter effect was less robust). Participants with low inhibitory control and marked food liking were less successful in weight reduction. CONCLUSION: These findings underscore the relevance of the interplay between cognitive control and food reward valuation in the maintenance of obesity. PMID- 27701174 TI - Changes in Waist Circumference among German Adults over Time - Compiling Results of Seven Prospective Cohort Studies. AB - AIM: This study aims to quantify longitudinal changes in waist circumference (WC) among adults aged 45-64 years in Germany. METHODS: Data of 15,444 men and 17,207 women from one nationwide and six regional prospective German cohort studies were analyzed. The sex-specific mean change in WC per year of follow-up was assessed for each study separately. Findings from the cohort-by-cohort analysis were combined by applying meta-analytic methods. Progression to central obesity (WC >= 102 cm in men and >= 88 cm in women) within a standardized period of 10 years was described for each study. RESULTS: The estimated mean change in WC per year of follow-up for all cohorts combined was 0.53 (95% confidence interval 0.29-0.76) cm/year for men and 0.63 (0.48-0.77) cm/year for women, but varied between the included studies. Within 10 years, about 20% of individuals with low WC (<94 cm in men; <80 cm in women) and about 50% of individuals with intermediate WC (94 102 cm in men; 80-88 cm in women) progressed to central obesity. CONCLUSION: The increase in mean WC with aging along with a profound increase of central adiposity is obviously and may have several adverse health effects. Obesity prevention programs should also focus on abdominal obesity. PMID- 27701175 TI - Evaluation of the Obesity Genes FTO and MC4R for Contribution to the Risk of Large Artery Atherosclerotic Stroke in a Chinese Population. AB - BACKGROUND: Obesity is a well-established risk factor for large artery atherosclerotic (LAA) stroke. The aim of the study was to explore whether obesity genes, such as MC4R and FTO, contribute to LAA stroke risk in the Chinese Han population. METHODS: 322 LAA stroke patients and 473 controls were recruited. Gene polymorphism of MC4R (rs17782313) and FTO (rs8050136 and rs9939609) were genotyped. RESULTS: No differences were observed in genotype frequencies of variants of FTO (rs8050136 and rs9939609) or MC4R (rs17782313) between LAA stroke patients and control subjects. However, rs17782313 of the MC4R gene was associated with LAA stroke susceptibility in smokers (rs17782313: p = 0.020, OR (95% CI) = 1.55 (1.07-2.23)) in the stratified analysis. Furthermore, multifactor dimensionality reduction analysis revealed that the combination of MC4R variant (rs17782313), hypertension and smoking habit was significantly associated with increased risk of LAA stroke (p < 0.0001, OR (95% CI) = 6.57 (4.79-9.01)). CONCLUSION: Our study indicated that the synergistic effects of MC4R variants, hypertension, and smoking habit contribute significantly to the risk of LAA stroke in the Chinese Han population. The finding revealed that obesity gene MC4R contribute to the risk of LAA stroke via a synergistic mechanism, which will provide new insight into the genetic architecture of LAA stroke. PMID- 27701176 TI - The Protective Effect of Febuxostat on Chronic Tacrolimus-Induced Nephrotoxicity in Rats. AB - BACKGROUND: The use of calcineurin inhibitors is a well-known risk factor for hyperuricemia in kidney transplant recipients. We evaluated the effect of febuxostat (Fx), a new uric acid-lowering drug, on hyperuricemia and renal injury in an experimental model of chronic tacrolimus (Tac)-induced nephropathy. METHODS: Chronic Tac nephropathy was induced by administering Tac (1.5 mg/kg/day) to rats on a low-salt diet (0.05%) with oxonic acid (OA, 2%, 0.2 g/kg/day) for 28 days. Two doses of Fx (5 and 10 mg/kg) were concomitantly administered with Tac or vehicle (Vh). We evaluated the effect of Fx on hyperuricemia by measuring serum uric acid (SUA) levels, fractional excretion of uric acid (FEUA), and urate transporters in Tac-induced nephropathy. The effects of Fx on Tac-induced renal injury were evaluated in terms of renal function and arteriolopathy, tubulointerstitial fibrosis, inflammation, and apoptosis. We evaluated oxidative stress as a protective mechanism via xanthine oxidase (XO) activity, and as a marker of oxidative stress (via evaluation of levels of 8-hydroxy-2' deoxyguanosine (8-OHdG) and 4-hydroxy-2-hexenal (4-HHE)). RESULTS: The Tac group showed higher SUA levels and lower FEUA than did the Vh group, but Fx treatment significantly decreased SUA levels in a dose-dependent manner, with an increase of FEUA at a high dose (10 mg/kg). Tac treatment increased urate-anion exchanger 1 and decreased organic anion transporter type 1 expression in renal tubular cells, but Fx treatment reversed the effects on those transporters. Impaired renal function and histological injury (interstitial fibrosis, inflammation, and arteriolopathy) in the Tac group were markedly improved by Fx administration. Increases in apoptotic cell death and activation of proapoptotic caspase-3 by Tac were remarkably decreased by Fx treatment. Tac administration increased the activity of XO in kidney tissue and serum, and the levels of 8-OHdG in urine and 8-OHdG and 4-HHE of kidney tissue, but combined treatment with Fx decreased the levels of these parameters. CONCLUSIONS: Fx is effective in controlling hyperuricemia and in preventing Tac-induced renal injury, via a reduction of oxidative stress. Therefore, a targeted therapy aimed at inhibiting uric acid by Fx may be a useful approach in the management of the progression of nephropathy in renal transplant patients treated with Tac. PMID- 27701177 TI - Uremic Toxin-Producing Gut Microbiota in Rats with Chronic Kidney Disease. AB - BACKGROUND: In patients with chronic kidney disease (CKD), many metabolites of gut microbiota retain in the body as uremic toxins (UTs). However, the kinds of bacteria producing UTs are rarely discussed. METHODS: We analyzed UT production and the composition of gut microbiota in CKD rats and cecectomized rats. AST-120, a spherical carbon adsorbent, was administrated to evaluate how the precursors of UT affect gut microbiota. Serum and urine levels of UTs were quantified by liquid chromatography/electrospray ionization-tandem mass spectrometry. Gut microbiota were analyzed using 454-pyrosequencing of the 16S rRNA gene. Operational taxonomic unit (OTU) clustering and UniFrac analysis were performed to compare gut microbiota among the groups. RESULTS: Serum and urine levels of indoxyl sulfate and phenyl sulfate were higher in CKD versus control rats (p < 0.05). AST 120 administration decreased UT production (p < 0.01) and changed overall gut microbiota composition in CKD rats. UT urinary excretion and gut microbiota composition changed in cecectomized rats, with the relative abundance of Clostridia- and Bacteroidia-affiliated species being significantly reduced (p < 0.01). We identified candidate indole- and phenol-producing intestinal microbiota, 3 Clostridia, and 2 Bacteroidia. These OTUs have a tryptophanase/tyrosine phenol-lyase gene in the closest sequenced genome out of the OTUs declined following cecectomy. CONCLUSION: Our data suggest that UT production is correlated with a subset of indigenous gut microbiota. However, UT may be induced by other non-symbiotic microbiota that are influenced by factors other than microbiota populations. The relationship between specific microbiota and UTs in patients requires further clarification.

PMID- 27701180 TI - Bilateral Endoscopic Lung Volume Reduction in Patients with Severe Emphysema. AB - Reducing hyperinflated areas in chronic obstructive pulmonary disease, either surgically or endoscopically, leads to improvement of functional parameters. It is unclear if bilateral treatment with endobronchial valves (EBV) aiming at total lobar occlusion is beneficial. The aim of this study was to assess the results after staged bilateral endoscopic treatment with EBV. This is a retrospective analysis of patients with severe airflow obstruction, who were treated bilaterally with EBV in two stages, aiming at subsequent atelectasis. Pre- and postintervention lung function parameters, the 6-minute walk test (6-MWT), complications, and follow-up were recorded. Sixteen patients were treated bilaterally in two stages. There was an overall improvement in lung function from baseline to second-treatment follow-up with an increase in FEV1 (23.57-29.21% of predicted) and a decrease in residual volume (299.21-240.10% of predicted) and total lung capacity (140.78-128.71% of predicted). The 6-MWT improved up to 54 m. After each procedure, 9 of 16 patients (56.25%) developed an atelectasis of the target lobe. Overall, pneumothorax occurred in 8 of 32 procedures (25%). No patient died. Patients benefitted from the first EBV treatment. The second treatment did not lead to marked improvements compared to the first treatment. Bilateral lung volume reduction with valves is possible; however, the current results seem not to justify bilateral valve treatment as a routine approach.

This new species, Grammatonotus brianne, is distinguishable from its described congeners by the following combination of characters: short anal-fin spines, rhomboid shaped caudal fin, lateral line usually disjunct, and live coloration. Herein we provide characters that distinguish callanthiids from other percoids and that distinguish Grammatonotus from Callanthias, the other genus in the family Callanthiidae, along with the description of the new species and short accounts of two other Grammatonotus, G. crosnieri and G. roseus, from the Coral Triangle.

AB - Gill (2004) recognised fifty-seven species in the Indo-Pacific genus Pseudochromis Ruppell (1835) but noted that the genus is undiagnosed cladistically and effectively serves as a catch-all for species that can't be placed in other pseudochromine genera (sensu Gill 2013). Since publication of Gill's revision, 13 additional species of Pseudochromis have been described, mostly based on recent collections from the highly diverse Coral Triangle area of the West Pacific (Gill & Allen 2004, 2011; Allen et al. 2008; Gill et al. 2009, 2012a,b; Gill & Williams 2011; Gill & Zajonz 2011; Allen & Erdmann 2012).

AB - Four species of stingrays of the genus Dasyatis occur in the Gulf of Gabes, but the taxonomic status of one of them, D. tortonesei has been questioned by several authors, and synonymized with D. pastinaca by some. The present study, using morphological comparisons and genetic analyses, demonstrates that there is a closely related species to D. pastinaca in the Gulf of Gabes, but distinguishable by several characters. This species is provisionally identified as Dasyatis cf. tortonesei, pending a more extensive comparative study including specimens from other regions of the Mediterranean Sea and eastern North Atlantic Ocean. PMID- 27701190 TI - A new species of Pisionidens (Aiyar & Alikunhi, 1943) (Annelida: Sigalionidae) from Southeastern Brazil. AB - Herein we describe specimens found along the southeastern coast of Brazil which belong to a new species, P. caissara sp. nov. This species differs from the other species of the genus by the glabrous antennae and palps, proboscis extending up to the sixth segment, jaws with smooth cutting edge and a pair of lateral wing like sheaths, two pairs of seriate male copulatory organs, first pair of testes on segment 19 and ovaries from segment 26 onward. Reproductive characters commonly used for characterizing species are also discussed. PMID- 27701191 TI - A review of the genus Minthodes Brauer & Bergenstamm (Diptera: Tachinidae) in Iran, with the description of a new species. AB - Minthodes susae Gilasian & Ziegler sp. nov. (Diptera: Tachinidae), from southwestern Iran, is described and illustrated, and compared with M. brevipennis (Brauer & Bergenstamm) from Turkey. A lectotype is recognised for Pseudomintho brevipennis Brauer & Bergenstamm (currently a species of Minthodes) and its designation is attributed to Mesnil. Minthodes pictipennis Brauer & Bergenstamm is newly recorded from Iran and Turkey, and M. latifacies Herting is reported from Iran for the first time. An identification key to the four Minthodes Brauer & Bergenstamm species known to occur in Iran is provided. Finally, new data are given on the intraspecific variation of Minthodes atra (Kugler). PMID- 27701192 TI - New species of tree cricket Oecanthus Serville, 1831 (Orthoptera: Gryllidae: Oecanthinae) from Reserva Natural Vale, Espirito Santo, Brazil, with chromosome complement. AB - A new species of the genus Oecanthus Serville, 1831 from Reserva Natural Vale, state of Espirito Santo, Brazil is described. The new species differs from other of this genus in characteristics of the pseudepiphallus main lobe, endophallic sclerites, posterior median lobe of the metanotal gland and black spots on the femora and tibiae. The chromosome number is 2n=16+XY?=18 and 2n=16+XX?=18, and this complement present one pair of autosomes less than the other five cytological studied species. PMID- 27701193 TI - Establishment of a new genus for Abraximorpha heringi and A. pieridoides
(Lepidoptera: Hesperiidae: Pyrginae: Tagiadini). AB - A new hesperiid genus, Albiphasma gen. nov., is described with Abraximorpha heringi as the type species. The new genus consists of two species: Al. heringi comb. nov. and Al. pieridoides comb. nov. The genitalia and hair tuft on the hind tibiae suggest that the new genus is related to the genus Pintara rather than the genus Abraximorpha to which the two species have been assigned. The geographic distribution is currently restricted to southern China and Vietnam. The adult, hind leg, wing venation and male genitalia of Al. heringi as well as relevant species are illustrated. PMID- 27701194 TI - Redescription of two Ctenidae (Araneae) from Taiwan. AB - Two ctenid species, Anahita maolan Zhu, Chen & Song, 1999 and Ctenus yaeyamensis Yoshida, 1998 from Taiwan are redescribed in detail based on both sexes. Anahita maolan is reported from Taiwan for the first time. For both species, Kenting National Park (southernmost Taiwan) is the southernmost known locality. PMID- 27701195 TI - Microscydmus trianguliceps Franz and Pseudoeudesis sulcata Franz transferred to Afroeudesis Franz (Coleoptera: Staphylinidae: Scydmaeninae). AB - Afroeudesis Franz was described as a subgenus of Pseudoeudesis Binaghi (Scydmaenini), with a single species from Tanzania. Recently, Afroeudesis was transferred to Glandulariini and elevated to generic rank, and the sub-Himalayan Nanoscydmus Jaloszynski was reduced to a subgenus of Afroeudesis. New surprising findings concerning Afroeudesis are presented here, extending the known geographic range of this enigmatic genus. Microscydmus trianguliceps Franz (Ivory Coast) and Pseudoeudesis sulcata Franz (SE Brazil) are transferred to Afroeudesis, each to a newly established subgenus: Eburneus subgen. n. and Eudesoides subgen. n., respectively. Afroeudesis (Eburneus) trianguliceps comb. n. and Afroeudesis (Eudesoides) sulcata comb. n. are redescribed. The genus name Eudesis is interpreted here as feminine; consequently Afroeudesis (Nanoscydmus) baoshanus is corrected to baoshana. The disjunct and possibly relict Gondwanan distribution of Afroeudesis is discussed. PMID- 27701196 TI - Two new Pediopsis species and a new Ruandopsis species (Hemiptera: Cicadellidae: Macropsinae) from Madagascar. AB - Three new species, Pediopsis tripartita, P. subtilis and Ruandopsis elongata spp. nov., from Madagascar are described. These species represent the first records of their respective genera in Madagascar. Images of adults and genitalia of the three species are provided. PMID- 27701197 TI - Three unusual species of Erythroneurini (Hemiptera: Cicadellidae) with description of new genera. AB - Two new genera of the leafhopper tribe Erythroneurini, Nedotepa gen. n. and Alerrawia gen. n., and three new species, Nedotepa curta sp. n. from Ghana, Alerrawia meliae sp. n. from Kenya, and Musbrnoia linnavuorii sp. n. from Indonesia, are described and illustrated. Nedotepa curta sp. n. has an unusually reduced ovipositor, a feature not previously recorded in Typhlocybinae. Musbrnoia linnavuorii sp. n. has extremely elongated parts of the male terminalia, which remarkably resemble parts of the female ovipositor. PMID- 27701198 TI - Physoschistura chhimtuipuiensis, a new species of loach (Teleostei: Nemacheilidae) from Mizoram, north-eastern India. AB - Physoschistura chhimtuipuiensis, new species, from a tributary of the Kaladan River in Mizoram, northeastern India, is distinguished from all other species of Physoschistura by a combination of the following characters: scales between pectoral- and pelvic-fin bases deeply embedded and sparsely set, lateral line incomplete with 56-63 pores, reaching slightly beyond the base of the last anal fin ray, a suborbital flap in male, 81/2 branched dorsal-fin rays and 8+7 branched caudal-fin rays. PMID- 27701199 TI - On Blaps Fabricius, 1775 (Coleoptera: Tenebrionidae) from Western Kazakhstan with description of a new species from Tyuleniy Archipelago (Caspian Sea). AB - A new species of darkling beetles Blaps caspica sp. n. from Western Kazakhstan Kulaly Island (Tyuleniy Archipelago, Caspian Sea) is described. This new taxon belongs to the 6th group of the 2nd section according to Seidlitz's classification and is most similar to Blaps kadyrbekovi G. Medvedev, 2004, B. lethifera Marsham, 1802 and B. parvicollis Zoubkoff, 1829. Blaps caspica sp. n. differs from B. kadyrbekovi by the presence of a hair tuft between male abdominal ventrites 1 and 2, from B. parvicollis by having narrow acute short spurs on the mesotibiae, the structure of the gastral spicula, ovipositor and female genital tubes, from B. lethifera by the slender elliptic body, punctated (not granulated) epipleura and the structure of the female genital tubes. Images, an identification key and local distribution are given for ten Western Kazakhstan species of the genus Blaps Fabricius, 1775. PMID- 27701200 TI - Two new species of Papuagrion Ris, 1913 (Odonata: Coenagrionidae) from New Guinea with a survey of distribution records for the genus. AB - Two new species of Papuagrion Ris, 1913 are described from Papua Province, Indonesia. These are P. marirobi sp .nov. from Japen Island and P. stellimontanum sp .nov., from the Star Mountains. The new species are, respectively, most closely allied to P. degeneratum Lieftinck and P. digitiferum Lieftinck. They bring the number of Papuagrion species to 28. New locality records of several other species are noted. PMID- 27701201 TI - The first riparian skink (Genus: Sphenomorphus Strauch, 1887) from Peninsular Malaysia and its relationship to other Indochinese and Sundaic species. AB - Recently discovered populations of skinks of the genus Sphenomorphus from central Peninsular Malaysia represent a new species, S. sungaicolus sp. nov., and the first riparian skink known from Peninsular Malaysia. Morphological analyses of an earlier specimen reported as S. tersus from the Forest Research Institute of Malaysia (FRIM), Selangor indicate that it too is the new riparian species S. sungaicolus sp. nov. Additionally, two specimens from the Tembat Forest Reserve, Hulu Terengganu, Kelantan and another from Ulu Gombak, Selangor have been diagnosed as new the species. The latter specimen remained unidentified in the Bernice Pauahi Bishop Museum, Honolulu, Hawaii since its collection in June 1962. Morphological and molecular analyses demonstrate that S. sungaicolus sp. nov. forms a clade with the Indochinese species S. maculatus, S. indicus, and S. tersus and is the sister species of the latter. Sphenomorphus sungaicolus sp. nov. can be differentiated from all other members of this clade by having a smaller SVL (66.5-89.6 mm); 39-44 midbody scale rows; 72-81 paravertebral scales; 74-86 ventral scales; a primitive plantar scale arrangement; and 20-22 scale rows around the tail at the position of the 10th subcaudal. PMID- 27701202 TI - A new South American Miocene species of 'one-holed' sand dollar (Echinoidea: Clypeasteroida: Monophorasteridae). AB - A new species of monophorasterid sand dollar, Monophoraster telfordi n. sp., is described from the Early Miocene basal horizons of the Chenque Formation of Patagonia, Santa Cruz Province, in southern Argentina. The new taxon raises the number of known species in the family to six, and represents first unequivocal record of the genus for the Early Miocene of South America. It is therefore also the oldest member of the genus. M. telfordi is characterized by its test width to length ratio, which is much higher than for the other two described species in the genus, but less than that known for the extremely wide members of the sister taxon, Amplaster. M. telfordi is also unusual among monophorasterids in lacking broad continuity between basicoronal and post-basicoronal plates in the oral interambulacra. A key is provided to all the known species of Monophorasteridae. PMID- 27701203 TI - Validity and Redescription of Profundulus balsanus Ahl, 1935 (Cyprinodontiformes: Profundulidae). AB - Profundulus balsanus was described by Ahl in 1935 and later placed in synonymy with P. punctatus. Recent molecular studies have demonstrated that specimens identified as P. balsanus belong to a distinct taxon. Herein we used a combination of morphometric, meristic, coloration and osteological data in order to demonstrate the distinctiveness of P. balsanus. Additionally, we used molecular data to reconstruct a phylogeny to place P. balsanus in a systematic context. Profundulus balsanus belongs to the punctatus clade within the genus Profundulus. It can be distinguished from P. oaxacae based on scale count in the lateral line and from P. punctatus based on differences in coloration in the anal fin. We provide a taxonomic key to all Mexican species of Profundulus. PMID- 27701204 TI - New genus and species of ant-like true bug (Hemiptera: Miridae) from the Canary Islands. AB - Perenotus gen. nov. is described based on males and females from the Canary Islands, Spain. This new genus is easily recognized by having a myrmecomorphic appearance and a scutellar hump in both sexes. Systellonotus stysi J. Ribes, Pagola-Carte et Heiss, 2008, was described based on females collected in Tenerife and La Palma, but careful examination showed that specimens from each island belong to different species, and can be transferred to the new genus Perenotus. As a result, Perenotus includes two species, P. stysi comb. n. for specimens from Tenerife and P. malobae sp. nov. for specimens from La Palma. In the present publication Perenotus gen. nov. and P. malobae sp. nov. are described, P. stysi female is redescribed, and P. stysi male is described for the first time. Illustrations of male and female general habitus and genitalia are provided. PMID- 27701205 TI - On the nature of Scleropages leichardti Gunther, 1864 (Pisces: Osteoglossidae). AB - The Australasian Saratoga (Pisces: Osteoglossidae) is currently recognised as comprised of two species Scleropages leichardti and S. jardinii. The Prussian explorer Ludwig Leichhardt (1813-c.1848) collected specimens of both species on his first major expedition across northern Australia but believed at the time that all specimens collected were from within one species. Details of the fate of these specimens are unclear as is the geographic origin of those specimens that ultimately made their way into museum collections. Gunther's 1864 description of the Southern Saratoga S. leichardti, purportedly from the Fitzroy River in Queensland to which it is restricted (although he erred and listed it as the Burdekin River) is meagre and inconsistent with contemporary accounts of the morphology of this species. It is also inconsistent with a subsequent description by de Castelnau in 1876 of the supposedly synonymous Osteoglossum guntheri. Finally, the description of S. leichardti by Gunther is largely consistent with meristic and morphometric information within Saville-Kent's (1892) description of the wide-spread Northern Saratoga S. jardinii. On balance, these inconsistencies, doubt about the provenance and geographic origin of type material and provenance of the original descriptions all strongly suggest that Gunther based his description of S. leichardti on material collected from within the range of the more widespread taxon currently recognised as S. jardinii. A revision of the Australian species within the genus Scleropages is warranted. PMID- 27701206 TI - Synchiropus sycorax, a new species of dragonet from the Philippines (Teleostei: Callionymidae). AB - Synchiropus sycorax n. sp. is described from six specimens (22.6-40.1 mm SL) collected from Jolo Island, Sulu Archipelago, Philippines. It appears to be most closely related to S. tudorjonesi, which ranges from the Maldive Islands through Indonesia and the Philippine Islands to southern Japan. The new species differs from S. tudorjonesi and other congeners in live coloration: head and body bright red, bright yellow ventrally, with prominent white spots on head (one spot or blotch over preopercular spine, two elongate spots behind middle of eye, and one spot behind upper part of eye at about 1 o'clock position) and body (in three rows, an uppermost row beginning below soft dorsal, tracking lateral line to caudal peduncle, a lowermost row extending from above anterior anal fin to caudal peduncle, and a middle row extending obliquely from above pectoral fin to anterior part of lowermost series of spots); males with pelvic fin and pelvic pectoral membrane bright yellow with broad bluish or greenish grey to black submarginal band across distal third of fin. PMID- 27701207 TI - A new genus of freshwater crab of the tribe Kingsleyini Bott, 1970 (Crustacea: Decapoda: Brachyura: Pseudothelphusidae) with description of a new species from Mato Grosso, Brazil. AB - A new genus and species of freshwater crab, Melothelphusa apiaka n. gen., n. sp., from Mato Grosso, Central Brazil is described and illustrated. Brasiliothelphusa dardanelosensis Magalhaes & Turkay, 2010, is assigned to the new genus Melothelphusa. Therefore, the genus Brasiliothelphusa Magalhaes & Turkay, 1986, is restricted to its type species B. tapajoense Magalhaes & Turkay, 1986. The new taxa can be easily separated from their close relatives by a suite of morphological characters from the first gonopod.

PMID- 27701209 TI - Illustrated and online catalog of type specimens of freshwater fishes in the Coleccion de Peces Dulceacuicolas of Instituto de Investigacion de Recursos Biologicos Alexander von Humboldt (IAvH-P), Colombia. AB - The catalog of type specimens of freshwater fishes deposited in the Coleccion de Peces Dulceacuicolas del Instituto de Investigacion de Recursos Biologicos Alexander von Humboldt (IAvH-P) is presented. This list includes 483 specimens in 65 lots representing 11 holotypes and 472 paratypes of 48 nominal species. Corrections, additions, and updating of information in the original descriptions are included in individual remarks for each catalog number entry and a gallery of pictures of holotypes or paratypes of each nominal species is also presented, which supplements some original descriptions lacking figures of their respective types. An online version of the catalog is available at http://humboldt.org.co/en/servicios/colecciones-biologicas/catalogo-de-tipos. PMID- 27701210 TI - A new species of Ituglanis (Siluriformes: Trichomycteridae) from the Tocantins and Paranaiba river basins, central Brazil, with remarks on the systematics of the genus. AB - Ituglanis goya, new species, is described from the Paranaiba and Tocantins river drainages, central Brazil. This is the first species of the genus described for the Upper Parana system and the second epigean Ituglanis for the Tocantins basin. The new species is distinguished from its congeners by the combination of a color pattern formed by longitudinal stripes and spots, absence of the anterior cranial fontanel, pattern of the cephalic laterosensory system and several fin-ray counts. Ituglanis goya exhibits morphological features that oppose the traditional hypotheses of alignment of the genus with the TSVSG clade of Trichomycteridae. These and other issues concerning the systematics of Ituglanis and the Trichomycterinae are critically discussed. PMID- 27701211 TI - Two new species of Pasipha Ogren & Kawakatsu (Platyhelminthes: Continenticola) from areas of deciduous forest in southern Brazil. AB - Two new species of Geoplaninae from southern Brazil are described herein. The new species, belonging to the genus Pasipha Ogren & Kawakatsu, 1990, can be distinguished from each other and from their congeners by colour pattern and characteristics of the copulatory apparatus, especially regarding the female organs and prostatic vesicle. Both new species seem to be endemic to areas covered by deciduous forest. PMID- 27701212 TI - Ultramorphological characteristics of unknown larva of Phloeonomus punctipennis Thomson, 1867 (Coleoptera; Staphylinidae; Omaliinae): an obligate saproxylic species: notes on chaetotaxy and ecological preferences. AB - The aim of the study was to describe the morphological ultrastructure, including chaetotaxy, of the previously unknown early (L1) and late (L2 3) larval instars of Phloeonomus punctipennis. The diagnostic larval characters for the genus Phloeonomus are proposed for the first time. Morphological differences between L1 and L3 refer only to the proportion of length of individual parts of antennae and legs as well as length proportion of urogomphi and their subapical setae. The chaetotaxy of the mature larvae of P. punctipennis and Dalotia coriaria, as a model of aleocharine larvae, is compared. Despite some identified differences, the chaetotaxic system proposed previously for Aleocharinae is successfully applied to the larva of P. punctipennis. It may most probably be also useful for larvae of other Omaliinae species. Also, information on geographical distribution and the ecological preferences of this species is provided, as is the information on accompanying insects. PMID- 27701213 TI - Idiocnemis schorri sp. nov., a new damselfly species from southern Papua New Guinea (Odonata: Platycnemididae). AB - Idiocnemis schorri sp. nov. is described from the Hindenburg and Muller Ranges and the Kikori River Basin of southern Papua New Guinea. The new species differs from all congeners by, among other characters, a unique colour pattern on the thorax. Characters of males and females are illustrated and compared to those of similar species from the Idiocnemis bidentata group. The new species is found along small, shallow rainforest streams and is currently known only from the Trans-Fly Foreland and Papuan Gulf Foreland areas of endemism. PMID- 27701214 TI - Description of a new Penaeidae (Decapoda: Dendrobranchiata) species, Farfantepenaeus isabelae sp. nov. AB - The pink shrimp, Farfantepenaeus subtilis, actually comprises two cryptic species confused under a single name. Despite morphological and molecular evidences accumulated since 1967, the new species confused with F. subtilis has never been formally described. In this paper, Farfantepenaeus isabelae sp. nov., is described and compared to its close relatives, F. brasiliensis, F. notialis, F. paulensis and F. subtilis s. str.. PMID- 27701215 TI - Taxonomic notes on the genus Tiliacea Tutt, 1896 (Lepidoptera, Noctuidae, Xylenini) with the description of a new species and a new genus. AB - The updated checklist and a general characterisation of the species-groups of the genus Tiliacea are presented. ''Xanthia yunnana'' Chen, 1999 syn. nov. is moved from the genus Tiliacea and synonymised with Gortyna joannisi (Boursin, 1928). One new species, Tiliacea annamaria sp. n. is described. ''Xanthia'' aurantiago (Draudt, 1950) is combined into the genus Tiliacea comb. nov. and a new genus, Tuttiana gen. nov. is established for ''Xanthia'' xanthophylla (Hreblay & Ronkay, 1998) comb. nov. and ''Cirrhia'' spalvota (Benedek & Saldaitis, 2011) comb. nov. PMID- 27701216 TI - Retrocitomyia Lopes, 1982 (Diptera: Sarcophagidae): new species, new records, key to males, and an updated catalog. AB - Prior to this work, Retrocitomyia Lopes (Diptera: Sarcophagidae) included ten recognized species distributed exclusively in the New World. We here add a new species to the genus, Retrocitomyia sisbiota sp. nov. from the Central-West Region of Brazil. Four other species of Retrocitomyia are recorded from this region for the first time, redescribed, compared, and illustrated, with emphasis on the male terminalia. Retrocitomyia paraguayensis Lopes is recorded from Brazil for the first time, R. fluminensis Lopes and R. retrocita (Hall) are newly recorded from the Brazilian states of Mato Grosso and Mato Grosso do Sul, and R. mizuguchiana Tibana & Xerez is newly recorded from the state of Mato Grosso do Sul. New generic diagnostic characters are added and the interpretation of some structures of the male terminalia is discussed. An updated catalog of all Retrocitomyia species and an identification key to the males of these species are also provided. PMID- 27701217 TI - The phylogeny of marine sculpins of the genus Icelinus with comments on the evolution and biogeography of the Pseudoblenninae. AB - The marine sculpins (Psychrolutidae) are a diverse percomorph family with notable morphological variation and repeated biogeographic patterns within the group. The psychrolutid genus Icelinus is unusual because it is one of the few near-shore members of the family that exhibits a trans-Pacific distribution; it has two species in the western Pacific and nine species in the eastern Pacific. Furthermore, the placement of Icelinus has been more inconsistent across molecular and morphological analyses than many genera. Previous phylogenetic studies have hypothesized sister taxa to Icelinus ranging from Antipodocottus, Chitonotus, and Stlengis, to a mixed clade of psychrolutids. The varied placements across these studies may be due to limited taxon sampling within Icelinus, and previous authors have never included western Pacific species of Icelinus in their analyses. This study tests the monophyly of the genus, examines the relationships between eastern and western Pacific species of Icelinus, and explores the relationships of Icelinus within Psychrolutidae. Our results show that the traditional grouping of Icelinus is polyphyletic. The eastern Pacific species of Icelinus are restricted to a clade sister to Furcina and Antipodocottus. The western Pacific species of Icelinus are recovered sister to the genus Stlengis. Given the polyphyly of Icelinus, the sister-group pairing of western Pacific species of Icelinus and Stlengis, as well as morphological similarity between the two groups, we recommend treating the western Pacific species of Icelinus as members of the genus Stlengis. With this taxonomic change, species in the genus Icelinus are now limited to the eastern Pacific, ranging from Alaska to Mexico. PMID- 27701218 TI - Three new species of glass sponges Pheronematidae (Porifera: Hexactinellida) from the deep-sea of the northwestern Pacific Ocean. AB - Three new glass sponge species of the family Pheronematidae are described in this study. Specimens were sampled in the northwestern Pacific Ocean during cruise DY125-35I expedition (July-August, 2014) conducted by the China Ocean Mineral Resources R&D Association. All samples were collected by the Chinese manned submersible Jiaolong HOV at a depth of 1627-2897 m. The three species belonging to three genera of the same family were observed, i.e., Platylistrum subviridum sp. nov. Poliopogon canaliculatus sp. nov. and Semperella retrospinella sp. nov. An unique form of the pinular ray of pinular pentactins with reclined spines is described for S. retrospinella sp. nov. This is also the first record of Platylistrum in the Pacific Ocean. PMID- 27701219 TI - New species and records of Microveliinae and Veliinae (Hemiptera: Heteroptera: Veliidae) from Colombia. AB - Euvelia orinoquia sp. nov. and E. meta sp. nov. from eastern Colombia are described, illustrated, and included in an updated identification key to the species of the genus. The former can be diagnosed by body length 2.30-2.50 mm, male fore femur without tufts of setae, longitudinal black stripe of female pronotum almost twice as wide as length of antennomere I, and female connexiva grayish black with silvery pruinosity on mesal portion, reddish on lateral portion. Euvelia meta sp. nov. can be diagnosed by female body length about 1.50 mm and maximum body width 0.90 mm, patches of silvery setae on female abdominal terga II-III and V-VII, and connexival segments I and IV-VI. Additionally, new records from the country are presented for species of Euvelia Drake, Husseyella Herring, Microvelia Westwood (Microveliinae), Oiovelia Drake & Maldonado Capriles, Platyvelia Polhemus & Polhemus, Stridulivelia Hungerford, and Veloidea Gould (Veliinae). PMID- 27701220 TI - A new species of Rhagovelia Mayr, 1865 (Hemiptera: Heteroptera: Veliidae) from Para State, with an updated key to Brazilian species of the robusta group. AB - Rhagovelia brunae Magalhaes & Moreira sp. nov., collected in the State of Para, Brazil, is described, illustrated, and compared with congeners. The new species belongs to the robusta group and can be differentiated from others by the general color black, abdominal sternum VII with black denticles laterally, male hind trochanter with 1-4 subequal spines plus a longer spine, and male hind femur lacking a medium spine between the proximal and distal rows of spines. Additionally, an updated identification key to species of the robusta group occurring in Brazil is presented. PMID- 27701221 TI - Status of the names of some hydroid species (Cnidaria, Hydrozoa), described from the Atlantic coast of Patagonia. AB - Thirty new species of benthic leptothecate hydroids were described and named from Patagonia in a 1991 PhD dissertation by Mohamed El Beshbeeshy. Although constituting nomina nuda under provisions of the International Code of Zoological Nomenclature (ICZN), the names of some species were used in several scientific publications between 1991 and 2011. In 2011, the dissertation of El Beshbeeshy was published in accordance with Article 8 of the ICZN. Several species-group names appearing in that work nevertheless fail to fully comply with certain articles of the code. The goal of this contribution is to review the nomenclatural availability of the names of those 30 new taxa, and to clearly establish the current status of El Beshbeeshy's material. Two of them were made available in 1999 as part of studies other than those of El Beshbeeshy, and correct authorship and date is here noted. Twenty-one of the nomina nuda were made available in a work published by El Beshbeeshy in 2011, although some constitute junior synonyms. Six of the new species-group names appearing in both the 1991 and 2011 works, established following a literature review of Patagonian species, were proposed without re-description, or designation of name-bearing types, or locations of such types. Most of them do not meet criteria of availability and remain nomina nuda. The status of each is discussed to avoid additional nomenclatural errors and continued taxonomic confusion. PMID- 27701222 TI - Taxonomy and immature stages of the Platystomatidae (Diptera: Tephritoidea) of Israel. AB - The Platystomatidae fauna of Israel is reviewed. Eleven species in two genera, Platystoma Meigen and Rivellia Robineau-Desvoidy, are recognized.

PMID- 27701223 TI - Two new troglobiotic palpigrades (Palpigradi: Eukoeneniidae) from Brazil. AB - Two new species of troglobiotic Brazilian palpigrades are described: Eukoenenia jequitinhonha sp. n., found in Lapa do Corrego do Vieira cave (Carai, Minas Gerais) and E. cavatica sp. n., found in Cazanga cave (Arcos, Minas Gerais). The importance of documenting the occurrence of troglobiotic species, even if they are represented by only a single specimen, is discussed. PMID- 27701224 TI - Some representative species of the tribe Holochlorini (Orthoptera: Tettigoniidae: Phaneropterinae) and the description of two new species from India. AB - In the present paper two new species of the genus Holochlora (Phaneropterinae: Holochlorini) have been described viz., Holochlora umranensis sp. nov., collected from Meghalaya, the North-eastern province, India (Ri bhoi 90 degrees 55'15 to 91 degrees 16' latitude and 25 degrees 40' to 25 degrees 21' longitude, 993 MSL) and Holochlora alsigarhensis sp. nov., collected from Southern-western, Rajasthan, (Udaipur N 24 34'17 to E 73 41' 30'' and Latitude 24.5713, Longitude 73.6915, 582 MSL), as additions to the previously known species of the genus that were earlier collected from the southern parts of India. Among these, four species are being reported for the first time from India including: H. brevifissa, H. fruhstorferi, H. japonica and Rectimarginalis profunda Liu & Kang. The key morphological characters of the head, pronotum, tenth abdominal tergite, subgenital plate, cerci, titillator and the ovipositor have been illustrated with suitable line drawings to distinguish the known, reported and new species, along with a key to the genera and species. PMID- 27701226 TI - Two new species of Stenaelurillus Simon, 1886 from India (Araneae: Salticidae: Aelurillina). AB - Stenaelurillus digitus sp. nov. and Stenaelurillus gabrieli sp. nov. are described from India. New distributional records for Stenaelurillus albus Sebastian et al., 2015 and Stenaelurillus lesserti Reimoser, 1934 and maps for these species are given. PMID- 27701225 TI - A revision and key for the tribe Diaphorolepidini (Serpentes: Dipsadidae) and checklist for the genus Synophis. AB - The genus Synophis contains a number of enigmatic species, distributed primarily in the Andean highlands of northern South America. Their extreme crypsis and rarity has precluded detailed study of most species. A recent flurry of collection activity resulted in the accession of many new specimens, and the description of 4 new species in 2015, doubling the number of described taxa. However, lingering questions remain regarding the assignment of many new and historical specimens, the morphological limits and geographical ranges of the species, and their phylogenetic relationships. We analyze new and existing morphological and molecular data to produce a new molecular phylogeny and revised morphological descriptions. We validate the previously unavailable tribe name Diaphorolepidini Jenner, Pyron, Arteaga, Echevarria, & Torres-Carvajal tribe nov., describe a 9th species Synophis niceforomariae Pyron, Arteaga, Echevarria, & Torres-Carvajal sp. nov., and offer new Standard Names in English and Spanish for the group: Andean Shadow Snakes and Culebras Andinas de la Sombra, respectively. A variety of features such as vertebrae and hemipenes show an interesting range of variation in the group, which should be evaluated in future studies, to refine species limits and diagnoses further. Cryptic and undiscovered diversity undoubtedly remains, and we hope this summary provides a robust basis for future work. PMID- 27701227 TI - Peristedion richardsi sp. nov. (Actinopterygii: Teleostei: Peristediidae) from Indonesian waters, with synonymy between Peristedion riversandersoni Alcock, 1894 and Peristedion nierstraszi Weber, 1913. AB - A new armored searobin, Peristedion richardsi sp. nov., is described on the basis of three specimens collected from the deep sea (485-600 m) off Java, Indonesia. This new species differs from the Indo-West Pacific congeners in having anterior edge of the 4th sensory pore of the rostral projection located anterior to the anterior edge of the premaxilla, perifacial rim prominent starting near anterior margin of lower jaw, spatulate rostral projection with very narrow interspace between both rostral projections, rostral projection width 1.33-1.73 in interspace between both rostral projections, and rostral projection with straight margin on medial side at base. It is clear that Peristedion nierstraszi Weber, 1913 is a junior synonym of Peristedion riversandersoni Alcock, 1894. In addition, a lectotype is designated for P. nierstraszi. PMID- 27701228 TI - New species and new records of genus Rhyacophila Pictet (Trichoptera: Rhyacophilidae) from Dabie Mountains, east-central China. AB - Three new species of Rhyacophila, Rhyacophila longiramata n. sp., Rhyacophila haplostephanodes n. sp., and Rhyacophila brevitergata n. sp., from the Dabie Mountains of east-central China, are described and illustrated. Rhyacophila longiramata n. sp. and R. haplostephanodes n. sp. both are highly specialized, which makes them very difficult to be put in any existing species group. Possible positions for these two species are discussed. Rhyacophila brevitergata n. sp. belongs to the R. nigrocephala Species Group. Rhyacophila spp. from Dabie Mountains are listed. PMID- 27701229 TI - Contribution to knowledge of Typhlocybinae (Hemiptera: Cicadellidae) in Thailand: first record of genus Arboridia Zachvatkin with description of three new species and a new synonymy.

A key for the identification of species of Arboridia from Thailand is provided. Arboridia (Arboridia) koreana Oh & Jung 2015 is synonymised with A. (Arboridia) agrillacea (Anufriev 1969). PMID- 27701230 TI - A new and endangered species of Kingsleya Ortmann, 1897 (Crustacea: Decapoda: Brachyura: Pseudothelphusidae) from Ceara, northeastern Brazil. AB - A new species of freshwater crab, Kingsleya attenboroughi n. sp., from the Arajara district, Ceara state, Brazil, is described and illustrated. The new species differs from congeners by having a short apical plate in the first gonopod, with anteriorly directed lobes and proximally angular; proximal lobe of the apical plate with conspicuous semicircular protuberance in mesial and sternal views; marginal process protruded, projecting mesially in sternal view and subquadrate in mesial view; and field of apical spines narrow, tapering distally, with small spines concentrated proximally. Opportunity is taken to illustrate K. gustavoi Magalhaes, 2005, the closest allied species of K. attenboroughi n. sp. A key for the species of Kingsleya Ortmann, 1897 is provided. PMID- 27701231 TI - Leptobasis linda sp. nov. from Ecuador (Odonata: Coenagrionidae). AB - Leptobasis linda is described from the Pacific lowlands of Ecuador. The coloration of mature individuals is superficially similar to the widespread L. vacillans, but structural and color characteristics differentiate L. linda from all congeneric species. The male caudal appendages and the female posterior margin of the prothorax are unique among Leptobasis. PMID- 27701232 TI - Leptogomphus tioman sp. nov. (Odonata: Anisoptera: Gomphidea) from Tioman Island, Peninsular Malaysia. AB - A new species Leptogomphus tioman is described based on male specimens collected from Tioman Island, Peninsular Malaysia. It is close to Leptogomphus risi Laidlaw in thoracic markings but is readily distinguished by its anal appendages and accessory genitalia. PMID- 27701233 TI - One new species of the genus Acosmetura (Tettigoniidae: Meconematinae) from Hubei, China. AB - One new species of the genus Acosmetura (Tettigoniidae: Meconematinae) is described, namely Acosmetura trigentis Wang, Bian & Shi sp. nov. from Hubei, China. In addition, morphological photographs and a distribution map are provided. The examined specimens are deposited in the Museum of Hebei University. PMID- 27701234 TI - The identity of the Carsidara species (Hemiptera: Psylloidea: Carsidaridae) associated with Firmiana simplex (Malvaceae) in Japan and Korea. AB - The records of the jumping plant-lice previously published under Carsidara shikokuensis (Miyatake, 1981) from Japan and C. marginalis Walker, 1869 from Korea are critically reviewed. It is concluded that both refer to the same species that is associated with Firmiana simplex (L.) W.Wight (Malvaceae). Carsidara shikokuensis shows no relevant morphological differences to C. limbata (Enderlein, 1926), and the two are synonymised: Carsidara limbata (Enderlein, 1926) = Carsidara shikokuensis (Miyatake, 1981) syn. nov. A record of C. marginalis from Korea is a misidentification of C. limbata. The latter is diagnosed and illustrated and differences to the former are discussed. The immatures of C. limbata are free-living on the leaves of Firmiana simplex and particularly the older instars secrete large amounts of flocculent wax and honeydew. Information on its potential usage as biological control agent of invasive Firmiana simplex in North America is briefly discussed. PMID- 27701235 TI - Morphology and COI barcodes reveal four new species in the lycieus group of Calisto (Lepidoptera, Nymphalidae, Satyrinae). AB - The predominantly Greater Antillean endemic genus Calisto Hubner, 1823 is highly diversified on several islands being more species rich on Hispaniola. We conducted expeditions during five years in the Dominican Republic resulting in new findings related with lyceius species group. Material belonging to this group was examined following the traditional morphological characters employed in genus taxonomy, and the COI barcode sequences obtained were analyzed through different approaches: Neighbor Joining clustering, ABGD, Maximum Likelihood (ML), and Bayesian Inference (BI). Analysis yielded 12 groups representing putative species: eight corresponding to previously named ones and four new species which are described in the present work: C. mariposa sp. nov., C. azua sp. nov., C. victori sp. nov., and C. samana sp. nov. The results also confirmed a single taxonomic entity within C. pulchella Lathy and the conspecific nature of C. franciscoi Gali and C. hendersoni. A dichotomic key for identification of species within the group is also given. Both phylogenetic reconstruction methods (ML and BI) employing molecular data achieved similar results with the relationships among the majority of taxa being supported by some ecological and morphological features. The exceptions were C. zangis Fabricius, C. raburni Gali, and C. pulchella, grouped together in a weakly supported clade. These species possess a highly differentiated adult and immature morphology which indicates an earlier divergence.

PMID- 27701237 TI - Review of subterranean Quedius, with description of the first hypogean species from the Russian Far East (Coleoptera: Staphylinidae: Staphylinini). AB - Hypogean species of Quedius, one of the largest North Hemisphere beetle genera, are reviewed in connection with the discovery of a new peculiar, brachypterous and microphtalmous species from the subgenus Microsaurus in the talus-based microhabitats of the Russian Far East. Morphology of that species here described as Quedius roma sp. n. suggests its affinity with the przewalskii-group from China and Nepal. Affinity of Q. roma to the abnormalis-group, a geographically more proximate and species-rich and presumably non-monophyletic assemblage of hypogean species from Japan and Taiwan, or to any other Holarctic Microsaurus is not supported morphologically. Two hypogean species from Europe, Q. bernhaueri Rambousek, 1915 and Q. doderoi Gridelli, 1922, are transferred from the subgenus Microsaurus to the subgenus Raphirus. The name Tenebrobius Rambousek, 1915, a subgenus where Q. bernhaueri was originally described, becomes a junior synonym of Raphirus Stephens, 1829.

The family Thelepodidae, as well as the two genera Streblosoma and Thelepus, is reported for the first time from Taiwanese waters. A synoptic table, including number of branchial filaments on segments 2 to 4, the presence/absence of eyespots, number of pairs of notopodia, uncinial dental formula of anterior and posterior tori, and type locality, is provided for all species of Thelepus. PMID- 27701240 TI - A new species of Amolops (Anura: Ranidae) from southern China. AB - A new species, Amolops albispinus sp. nov. is described based on a series of specimens collected from Mt. Wutong, Shenzhen, Guangdong Province, China. The new species can be distinguished from other known congeners by molecular divergence in the mitochondrial COI and 16S rRNA gene and morphological characters including presence of white conical spines on the lips, loreal and temporal regions, excluding the tympanum; small body, SVL 36.7-42.4 mm in adult males and 43.1-51.9 mm in adult females; very rough dorsal skin of body with numerous raised large warts; olive-brown dorsum with dark brown blotches; strongly developed vomerine teeth; absence of vocal sacs; absence of tarsal glands; absence of dorsolateral folds; presence of circummarginals groove on the disk of first finger; and absence of outer metatarsal tubercles. At present, the genus Amolops contains 51 species, of which 23 occur in China. PMID- 27701241 TI - Wrapped in flames: Corydoras hephaestus, a new remarkably colored species from the Rio Madeira basin (Teleostei: Callichthyidae). AB - A new species of Corydoras is described from the upper Rio Machado, Rio Madeira basin, Rondonia State, Brazil. The new species can be distinguished from its congeners by the absence of contact between the posterior process of the parieto supraoccipital and the nuchal plate; a ventral laminar expansion of the infraorbital 1 conspicuously developed; and the posterior margin of the pectoral fin spine with serrations along almost of its entire length, only lacking in the distal portion. Additionally, Corydoras hephaestus possesses dorsal and pectoral spines short, and exhibits an unusual color pattern in life. The conservation status of the new species and other endemic species are briefly commented. PMID- 27701242 TI - Contributions to the knowledge of the biodiversity of Heteroptera (Insecta) in the Southern Cone, Argentina. AB - Insect studies for different regions are scarce as most of the material is collected in isolation, thus preventing extensive taxonomic listings. Conducting inventories of terrestrial biodiversity in a specific area is an arduous task, with many obstacles: mainly the lack of data on taxonomic and geographical distribution necessary to study them. The aim of this work is to present new contributions to the geographical distribution of Heteroptera in the Pampean, Espinal and Monte phytogeographic provinces, in the central region of Argentina, Southern Cone. Ten samples were taken, using the following methods, beating sheet, light trap and G-Vac (garden-vacuum). Each point within the site was sampled by each type of trap for one minute, leading to a total of 10 minutes per capture method in each site, except the light tramp. Twenty-two species are recorded for the first time in the central region of Argentina, Southern Cone. PMID- 27701243 TI - Revision of the South American genus Xiphiola Bolivar, 1896 (Orthoptera: Acrididae: Ommatolampidinae: Abracrini). AB - The Neotropical genus Xiphiola Bolivar, 1896 is revised. It includes two valid species: Xiphiola borellii Giglio-Tos, 1900 and Xiphiola cyanoptera (Gerstaecker, 1889). The genus and the species are redescribed and diagnostic characters are provided along with illustrations of each species. A lectotype and paralectoype for X. cyanoptera are here designated. We also include new morphological characters from male and female genitalia, and external characters that have not been employed until now. We present the distribution map based on material examined, as well as a key to species.

PMID- 27701247 TI - Taxonomic studies on potter wasps (Hymenoptera: Vespidae: Eumeninae) of south India. AB - The family Vespidae is represented in India by four subfamilies: Vespinae, Polistinae, Stenogastrinae, and Eumeninae. The subfamily Eumeninae is the most species rich among the Vespidae. The potter wasps of south India are reviewed for the first time to comprise 31 valid genera. The genera Discoelius Latreille, 1809, Coeleumenes van der Vecht, 1963, Euodynerus Dalla torre, 1904, and Pseudonortonia Giordani Soika, 1936 are newly reported from south India. Diagnoses and a key to south Indian eumenine genera are given. A total of 72 species and subspecies are listed, 15 of them are newly reported from Karnataka and two species from Kerala. PMID- 27701248 TI - Reconsideration of the genera Merogomphus Martin, 1904, and Anisogomphus Selys, 1857, including erection of a new genus, with a new species and discussion of additional specimens from Cambodia. AB - In the current sense, Merogomphus Martin, 1904, is an artificial genus. It includes two unrelated groups of species: those with lyrate cerci with or without an outer spine and those with simple cerci, plus two species with large and broad epiproct branches placed in Merogomphus obviously in error. At the same time a number of species similar and obviously related to the former group were described from China in the genus Anisogomphus Selys, 1857. To resolve this taxonomic tangle, the genus Merogomphus is restricted to include only species with lyrate cerci: M pavici (Martin, 1904) (the type species), M. longistigmus (Fraser, 1922), M. vandykei (Needham, 1930), M. femoralis (Laidlaw, 1931), M. vespertinus (Chao, 1999) and M. torpens (Needham, 1930). A new genus Euthygomphus (type species: Platygomphus martini Fraser, 1922) is erected to contain species with simple cerci and moderately divergent epiproct branches, formerly attributed to either Merogomphus or Anisogomphus: Euthygomphus parvus (Kruger, 1899) comb. nov., E. martini (Fraser, 1922) comb. nov., E. koxingai Chao, 1954 comb. nov., E. chaoi Liu 1991 comb. nov., E. jinggangshanus Liu, 1991 comb. nov., E. yunnanensis Zhou et Wu, 1992 comb. nov. Euthygomphus schorri Kosterin, 2016, sp. nov. is described (type locality: Cambodia, Mondulkiri Province, 3.5-3.8 km ESE of Sen Monorom, holotype in RMNH), A new synonymy Merogomphus chaoi Yang & Davies, 1993 = Anisogomphus pinratani Hamalainen, 1991, and a new combination Anisogomphus tamdaoensis (Karube, 2001) comb. nov. are proposed [corrected]. The published records of 'Merogomphus parvus' from Laos, Thailand, Vietnam, Cambodia and Vietnam are reidentified as E. yunnanensis, and new records and illustrations of this species from Cambodia are provided. PMID- 27701249 TI - New species and records of Galumnidae (Acari, Oribatida) from the Philippines. AB - We collected 19 species in eight genera of poronotic oribatid mites of the family Galumnidae from the Philippines. Five species, Galumna (Cosmogalumna) areticulata Ermilov, Sandmann, Klarner, Widyastuti & Scheu, 2015, G. (Neogalumna) tolstikovi Ermiov & Anichkin, 2014, Pergalumna (Pergalumna) crassipora Mahunka, 1995, P. (Pergalumna) margaritata Mahunka, 1989 and Trichogalumna nipponica (Aoki, 1966), the subgenus Galumna (Neogalumna) and the genus Trichogalumna are recorded for the first time in the fauna of this country. Three new species of the genera Pergalumna, Setogalumna and Trichogalumna are described. Pergalumna (Pergalumna) capualensis sp. nov. differs from P. (Pergalumna) bimaculata Hammer, 1973 and P. (Pergalumna) remota (Hammer, 1968) by the larger body length and the presence of strong teeth on prodorsum. Setogalumna minisetosa sp. nov. differs from S. luzonica Ermilov & Corpuz-Raros, 2015 by the smaller body size, the presence of minute interlamellar and notogastral setae, median pore and elongated notogastral porose areas A3, and the absence of notogastral porose areas A2. Trichogalumna interlamellaris sp. nov. differs from T. seminuda Balogh, 1960 by the larger body size, the presence of anterior notogastral margin and small bothridial heads, the absence of notogastral porose areas A2, and the localization of adanal setae ad3. Supplementary description of Pergalumna (Pergalumna) crassipora Mahunka, 1995 is presented. PMID- 27701250 TI - Review of the leafhopper tribe Stenometopiini (Hemiptera: Cicadellidae: Deltocephalinae) from China with description of four new species. AB - The leafhopper tribe Stenometopiini is revised from China. Two genera are included: Hodoedocus Jacobi with two species and Stirellus Osborn & Ball with thirteen species of which four are new: S. daii sp. nov., S. multipunctatus sp. nov., S. neospeciosus sp. nov., and S. translucidus sp. nov. S. yeongnamensis (Kwon & Lee) is newly recorded for China. Five new synonyms are proposed: Viridomarus brevialatus Xing et al. and Viridomarus laticellus Xing et al. as junior synonyms of S. capitatus (Distant); Aconura bipunctella Matsumura and Paivanana centristriata Dai & Li as junior synonyms of S. indrus (Distant); Aconura rubrofasciata Matsumura as junior synonym of S. rubrolineatus (Distant). Two new combinations are erected and one combination is reinstated (see checklist). Species are described and illustrated together with keys provided for their separation. Lectotypes are designated for Typhlocyba indra Distant and Arya rubrolineata Distant.

AB - The species of the genus Stenus Latreille from Tianmushan Mountain Chain, North Zhejiang, East China, are reviewed and three new species are described: S. tianmushanus sp. n., S. tonghanggangus sp. n., and S. pseudomicuba sp. n. Diagnostic characters of the new species are illustrated and a key to species of the area is provided. PMID- 27701252 TI - A new species of treefrog (Litoria) from Cape York Peninsula, Australia. AB - We describe a new species of treefrog from northern Australia. Litoria bella sp. nov. is morphologically and genetically most similar to frogs in the L. gracilenta and L. chloris groups but is distinguished from all members in these groups by a combination of a moderately large male body size (34.5-41.8 mm SVL), near-immaculate green dorsum, orange venter, bright orange digits and webbing, bluish purple lateral surfaces of the thighs, no pale canthal stripe, white bones, and a highly-pulsed, single-note, male advertisement call with a pulse rate of 56-64 pulses/s and dominant frequency of 2.6-2.8 kHz. Litoria bella sp. nov. has a patchy distribution across the Cape York Peninsula, inhabiting rainforest and monsoon vine thicket in close association with watercourses. The new species' affinities lie with L. auae from southern New Guinea rather than with L. gracilenta from eastern Australia. Molecular data suggest that the L. gracilenta group should be expanded to include L. chloris and L. xanthomera, two moderately large green treefrogs from eastern Australia. PMID- 27701253 TI - The genus Prothrombosternus (Coleoptera: Curculionidae: Molytinae) rediscovered: a male from Rubeho Mountains, Tanzania. AB - A male specimen of the monotypic weevil genus, Prothrombosternus Voss, 1965, so far known on the basis of only five syntypes from Mt. Meru and Mt. Hanang, Tanzania, is reported from the Rubeho Mountains, Tanzania. The lectotype of Prothrombosternus tarsalis Voss, 1965 is designated using a male from Mt. Meru. The Rubeho specimen shares the same external and genital morphological characters with the lectotype (both extensively illustrated) and, therefore, both are considered conspecific. The DNA barcode of the Rubeho specimen is publicly available at dx.doi.org/10.5883/DS-PROTHRO. All six known specimens of Prothrombosternus are flightless and were found by sifting leaf litter at elevations between 1833-2500 m in wet Afromontane forests. The genus is, therefore, thought to be restricted to this highly fragmented habitat threatened by human encroachment. Presence of the genus on both geologically old (Rubeho Mountains; >10Ma) and young (Mt. Meru and Mt. Hanang volcanoes, <2Ma) forested highlands suggests presently unknown means of dispersal. The phylogenetic position of the genus is unknown and its taxonomic placement in Cycloterini cannot be presently tested. PMID- 27701254 TI - Notes on west Palaearctic species of the genus Trigonurus Mulsant, 1847 (Coleoptera: Staphylinidae: Trigonurinae). AB - The subfamily Trigonurinae Reiche, 1866 is a monogeneric subfamily of the large family Staphylinidae with an Holarctic distribution. The genus was the subject of a revision (Blackwelder, 1941). Seven species are known from northern America (Blackwelder, 1941; Herman, 2001), two species from the western Palaearctic and two, recently described species from China (Schulke & Smetana, 2015; Kishimoto, 2000; Schulke, 2006). PMID- 27701255 TI - A new species of the genus Apollophanes O. Pickard-Cambridge, 1898 (Araneae: Philodromidae) with the first record to the Atlantic rainforest. AB - Apollophanes has a wide distribution, with some species in Asia and most of the species recorded from North and Central America (World Spider Catalog 2016). New species described from the Galapagos Islands by Baert (2013) have extended the genus range to South America. According to Dondale and Redner (1975) and Dondale and Redner (1978), the species of Apollophanes have a moderately low prosoma, usually of yellow to orange-brown color and with black or brown spots on the lateral margins. The posterior eyes distances are equally spaced and the legs are long, slender and speckled with dark spots, with leg I usually being longer than IV (characteristic observed only in the male exemplar of the new species). The opisthosoma has a conspicuous heart mark, dark longitudinal spots on the lateral margins and a pale ventral region with purple spots. According to Dondale and Redner (1975) and Logunov (1996), Apollophanes shares some features with species of Cleocnemis, Thanatus and Tibellus, e.g. the shape and coloration patterns of the dorsal shield of the prosoma, as well as the slender legs with dark spots. Apollophanes can be distinguished from Cleocnemis by the presence of two tibial apophyses (ventral and retrolateral) and by the size of the copulatory ducts openings that are long slits that reach the posterior margin of epigastric furrow in Apollophanes, while in Cleocnemis the openings are shorter and situated in central region of the median septum (Dondale & Redner 1975). Apollophanes differs from Thanatus by the presence of macrosetae on the prolateral region of the metatarsus, and differs from Tibellus by the size of leg IV, that is longer than leg I (Dondale & Redner 1975). PMID- 27701256 TI - One new species of the subgenus Xizicus (Zangxizicus) (Orthoptera: Tettigoniidae: Meconematinae) from China. AB - The paper reports one new species of the tribe Meconematini, Xizicus (Zangxizicus), curvus Chang & Shi sp. nov., and supplies the character photographs of the new species and Xizicus(Zangxizicus) tibeticus Wang, Jing, Liu & Li, 2014. PMID- 27701257 TI - Confirmation of the occurrence of the sandbar shark Carcharhinus plumbeus (Nardo, 1827) at Norfolk Island, Tasman Sea. AB - The occurrence of the sandbar shark Carcharhinus plumbeus at Norfolk Island is confirmed. Carcharhinus plumbeus occurs over the mid to outer insular shelf from 38 m to at least 53 m depth, and appears to be at least as abundant as C. galapagensis in this habitat. No C. plumbeus were caught from shore despite most fishing effort being land-based. The presence of young-of-the-year confirms C. plumbeus breeds on the Norfolk Island shelf. Size at birth and the timing of parturition appear similar to that reported for eastern Australia. PMID- 27701258 TI - The identity of Calliphora bezzii Zumpt, 1956 (Diptera, Calliphoridae). AB - The holotype male of a nominal species described from Italy, Calliphora bezzii Zumpt, 1956, including a microscope slide of its terminalia, was examined. The holotype is shown to belong to the Nearctic taxon Calliphora latifrons Hough, 1899. Thus, Calliphora bezzii is a junior synonym of C. latifrons, syn. nov. PMID- 27701259 TI - New records of Panchaetothripinae from Japan (Thysanoptera, Thripidae). AB - Until now, 16 species of Panchaetothripinae in 11genera have been recorded from Japan (Kudo 1992a,b). Recently, however, three further species were found, in the genera Phibalothrips and Caliothrips, and one purpose of this report is to record these two genera from Japan for the first time. The four known species of Phibalothrips occur mainly in the Old World tropics, and are associated with grasses (Mound 2011), whereas the 22 known species of Caliothrips are found in the tropics and subtropics worldwide and feed on a range of different plants including grasses. In this article, P. rugosus, C. punctipennis and C. tongi are newly recorded from Japan, and the male of P. rugosus and second instar larva of C. tongi are described for the first time. Moreover, an identification key to the known species of Phibalothrips is provided. Larval chaetotaxy is based on Heming (1991) and Vierbergen et al. (2010). The specimens studied are deposited in Yokohama Plant Protection Station, Naha Plant Protection Station and the authors' collection. PMID- 27701260 TI - Further studies on south eastern Asian Luciolinae: 1. Sclerotia Ballantyne,
a new genus of fireflies with back swimming larvae 2. Triangulara Pimpasalee, a new genus from Thailand (Coleoptera: Lampyridae). AB - Sclerotia Ballantyne gen. nov. is established for seven species. Sclerotia aquatilis (Thancharoen, 2007), Scl. brahmina (Bourgeois, 1890), Scl. carinata (Gorham, 1880), Scl. flavida (Hope, 1845), Scl. seriata (Olivier, 1891), and Scl. substriata (Gorham, 1880) are transferred from Luciola Laporte. Sclerotia fui sp. nov. from China is described as new. Luciola cingulata Olivier, 1885 is synonymised with Luciola substriata Gorham. Luciola formosana Pic, 1916 is removed from synonymy with Luciola substriata and newly synonymised with Luciola flavida (Hope). Males are characterised by linear elytral punctation, a set of three sclerites surrounding the aedeagal sheath and a light organ in ventrite 7 with emarginated anterior margin. Associated females lack bursa plates. Larvae associated for three species are back swimmers, having heavily sclerotised exoskeleton and a metapneustic respiratory system. Males and associated females are keyed. Analysis of molecular evidence for Chinese populations of three species indicates monophyly of Sclerotia Ballantyne gen. nov. and distinct separation from other genera.Triangulara Pimpasalee gen. nov. is described from Tri. frontoflava Pimpasalee gen. et sp. nov. from Thailand. It is superficially similar to Sclerotia gen. nov. but larger, and specimens in collections appear to have been confused with the similarly coloured Scl. substriata (Gorham) comb. nov. Males differ in having an elongate triangular light organ in ventrite 7 and are without sclerites around the aedeagal sheath. Larvae are not reliably associated but may be aquatic.

AB - A survey on species of the genus Zelurus Hahn, 1826 (Reduviidae) occurring in Brazilian caves is provided. Zelurus tambejua sp. n. and Zelurus gerevatinga sp. n. collected from caves in Brazil are described. Comments about the current and potential distribution of the genus as a whole and of species of Zelurus found in caves for South America are also provided. PMID- 27701262 TI - Taxonomic revision of the Dasypus kappleri complex, with revalidations of Dasypus pastasae (Thomas, 1901) and Dasypus beniensis Lonnberg, 1942 (Cingulata, Dasypodidae). AB - Dasypus kappleri is the largest species of the genus Dasypus and is restricted to the Amazonian rainforest biome. Over the last century, related taxa have been described and synonymized without comprehensive analyses, and the current classification involving two subspecies, Dasypus k. kappleri and Dasypus k. pastasae, has never been revised. The aim of this work is to clarify the taxonomy of Dasypus kappleri through integrative morphological and morphometric analyses. We examined 70 specimens housed in scientific collections as well as photographs of the type specimens of five nominal taxa. Three methodologies (discrete characters, linear and geometric morphometrics) were employed. All results converged on the recognition of three allopatric groups, each with diagnostic qualitative and quantitative traits, that we recognize as full species: Dasypus kappleri Krauss, 1862, occurs in the Guiana shield; Dasypus pastasae (Thomas, 1901) is distributed from the eastern Andes of Peru, Ecuador, Colombia, and Venezuela south of the Orinoco River into the western Brazilian Amazon; and Dasypus beniensis Lonnberg, 1942, occurs in the lowlands of Amazonian Brazil and Bolivia to the south of the Madre de Dios, Madeira, and lower Amazon rivers. This revision raises to nine the number of living species of Dasypus. PMID- 27701263 TI - Two new species of brackish-water Macrostomum (Platyhelminthes, Macrostomida) from southern China. AB - Two new species of brackish-water Macrostomum (M. zhujiangensis n. sp. and M. baoanensis n. sp.) were described based on samples collected from the littoral zone of the Zhujiang Estuary. These are the first records of brackish-water Macrostomum from southern China. Macrostomum zhujiangensis n. sp. and M. baoanensis n. sp. differ from other similar species in the length and morphology of the penis stylet. The penis stylet of M. zhujiangensis n. sp. is C-shaped and its distal opening has a beveled edge. The penis stylet of M. baoanensis n. sp. is J-shaped and the distal region is thicker than other parts of the penis stylet. Molecular phylogenetic analysis supports the establishment of the new species. PMID- 27701264 TI - The Pinnotheridae of the northeastern Pacific (Alaska to Mexico): zoogeographical remarks and new bivalve hosts (Crustacea, Brachyura, Pinnotheridae). AB - New bivalve host records for four pinnotherid crabs of the Mexican Pacific are reported: Fabia subquadrata Dana, 1851, in Modiolus capax (Conrad, 1837); Opisthopus transversus Rathbun, 1893, in Tivela stultorum (Mawe, 1823); Pinnaxodes gigas (Green, 1992), in Pinna rugosa (Sowerby, 1835), and Panopea generosa Gould, 1850; and Tumidotheres margarita (Smith, 1870), in Nodipecten subnodosus (Sowerby, 1835). The southernmost distribution of F. subquadrata is extended to about 600 km along the west coast of the Baja California Peninsula; the distribution of P. gigas is extended outside the Gulf of California more than 1000 km north to San Quintin, on the west coast of Baja California; and the range of T. margarita is restricted on the west coast of Baja California to Scammon's Lagoon, Baja California Sur and Playa Kino Viejo, Sonora in the central region of the Gulf of California, Mexico to Panama. Based on the new material, new information on taxonomy, ecology, and life history is provided for each of these species. Pinnotheres nudus Holmes, 1895 is restored as a valid species and is removed from its synonymy with O. transversus. An updated checklist with remarks on zoogeography for the 60 pinnotherid species, included in 23 genera, of the northeastern Pacific region (Alaska to the Mexican tropical Pacific) is given.

(Hemiptera: Heteroptera: Pentatomidae: Pentatominae: Carpocorini). AB - The genus Calagasma Bergroth synonymized with the genus Epipedus Spinola by Rolston (1987) is reinstated. The diagnostic characters of the genus Calagasma are redefined, pictures of the Calagasma margarita syntype and recently collected specimens from French Guiana, including males hitherto unknown are presented. Calagasma eclipsa, a new species from French Guiana is described. Epipedus is redescribed and a new species Epipedus rolstoni is described. PMID- 27701266 TI - A new species of the Cyrtodactylus (Geckoella) collegalensis (Beddome, 1870) complex (Squamata: Gekkonidae) from Western India. AB - A new species of Cyrtodactylus (Geckoella) from the C. collegalensis complex is described based on a series of specimens from western and central India. Morphological and molecular data support the distinctiveness of the new form, which can be diagnosed from other Cyrtodactylus (including other Geckoella) species by its small body size (snout to vent length to 56 mm), the absence of precloacal and femoral pores, no enlarged preanal or femoral scales, and a dorsal scalation consisting wholly of small, granular scales. The new species is most closely related to C. collegalensis, C. speciosus and C. yakhuna, from which it differs by the presence of a patch of enlarged roughly hexagonal scales on the canthus rostralis and beneath the angle of jaw, its relatively long limbs and narrow body, and a dorsal colour pattern of 4-6 pairs of dark spots. PMID- 27701267 TI - The distribution of the Bururi Long-fingered Frog (Cardioglossa cyaneospila, family Arthroleptidae), a poorly known Albertine Rift endemic. AB - The species diversity of the frog genus Cardioglossa (family Arthroleptidae) is concentrated in the Lower Guinean Forest Zone of Central Africa with most of the 19 species occurring in Cameroon and neighboring countries (Amiet 1972a,b; Blackburn 2008; Hirschfeld et al. 2015). These small leaf-litter frogs are typically found in primary or secondary forest, have shrill whistling calls, are characterized by a variety of color patterns, and lay terrestrial eggs that hatch and develop into elongate, stream-adapted tadpoles (Amiet 1972a,b, 1973; Rodel et al. 2001; Hirschfeld et al. 2012). One of the most poorly known species-the Bururi Long-fingered Frog Cardioglossa cyaneospila Laurent, 1950-is also among the most geographically peripheral to the rest of the species diversity. To date, it is known only from two locations in Burundi and four in eastern Democratic Republic of Congo, regions in which armed conflicts have long hampered scientific research. In this short contribution, we (1) document both new and long unpublished records of C. cyaneospila, associate these with known museum records, and extend its geographic range, (2) highlight fruitful areas for future field surveys based on predicting an environmental envelope for this species, and (3) summarize what little is known of its natural history. PMID- 27701268 TI - The Afrotropical genus Rhinolaetia Schouteden, 1965 and its systematic position within Scutelleridae (Hemiptera: Heteroptera). AB - The monotypic Afrotropical genus Rhinolaetia Schouteden, 1865 (Hemiptera: Heteroptera: Scutelleridae) is redescribed. The head, wings, female genitalia and habitus of Rhinolaetia overlaeti Schouteden, 1965 are illustrated. Morphological features of Rhinolaetia and selected representatives of six scutellerid subfamilies are listed and compared. The systematic position of this genus is briefly discussed. Close affinity of Rhinolaetia overlaeti with representatives of subfamilies Odontotarsinae and Odontoscelinae is observed. PMID- 27701269 TI - Hybothoracaphis, a new genus of Nipponaphidini (Hemiptera, Aphididae, Hormaphidinae) from China and its phylogenetic placement based on multiple genes. AB - Hybothoracaphis gen. nov. with one new species Hybothoracaphis laevigata sp. nov. on Quercus aquifolioides from Tibet, China is described and illustrated in the aphid tribe Nipponaphidini. The phylogenetic position of the new genus within Nipponaphidini is investigated using multiple genes, and a key to Hybothoracaphis and allied genera is provided. PMID- 27701270 TI - A new species of seahorse (Teleostei: Syngnathidae) from the South China Sea. AB - A new species of seahorse, Hippocampus casscsio sp. nov. was collected over shallow seagrass beds in Beibu Bay, China. This species is diagnosed from all other seahorse species by morphological characters, including the lower number of tail rings (35); 15 pectoral-fin rays; 16 dorsal-fin rays; a rounded nuchal plate without a raised coronet; a snout length 30% head length; two cheek spines and a dark brown coloration. In addition, molecular analysis showed all individuals of the new species clustering together suggesting a monophyletic lineage. This combined analysis supports the distinctness of H. casscsio sp. nov. as a new species, which is described herein. PMID- 27701271 TI - First records of the cremastocheiline genus Clinterocera Motschulsky, 1858 from the Indonesian island of Sulawesi, with description of a new species (Coleoptera: Scarabaeidae: Cetoniinae). AB - A new species of the myrmecophilous Asian genus Clinterocera Motschulsky, 1858 (Coleoptera: Scarabaeidae: Cetoniinae: Cremastocheilini) is recorded from three localities on different parts of Sulawesi island (Indonesia). These are the first published records of the genus from the island. The taxonomic position and ecology of Clinterocera are briefly discussed. The male holotype of Clinterocera heinrichi new species comes from Central Sulawesi while a second male specimen from North Sulawesi male seems different enough to be placed in another species group taxon, but more material needs to be examined first. PMID- 27701272 TI - Thirteen new species of the spider genus Pholcus Walckenaer, 1805 (Araneae: Pholcidae) from China.

Five species including Dina punctata punctata Johannson, 1927, Erpobdella monostriata (Lindenfeld & Pietruszynski, 1890), E. vilnensis (Liskiewicz, 1925), Trocheta haskonis Grosser, 2000 and Glossiphonia concolor (Apathty, 1888) are new records for the country. PMID- 27701275 TI - Four colorful new species of dragon millipedes, genus Desmoxytes Chamberlin, 1923, from northern Thailand (Diplopoda: Polydesmida: Paradoxosomatidae). AB - Four new dragon millipede species of the genus Desmoxytes from northern Thailand are described and illustrated: D. des sp. n. from Chiang Mai Province, D. breviverpa sp. n. from Phrae Province, D. takensis sp. n. from Tak Province and D. pinnasquali sp. n. from Phitsanulok Province. The new species were compared with type specimens of closely related species and were all found to exhibit explicit morphological differences from these. They can be distinguished from other members of Desmoxytes by the shape of the gonopods, the sternal process between male coxae 4, the pattern of spines or tubercles on the metaterga, and the shape of the paraterga. The coloration of all new species is clearly aposematic: ranging from purple-pink to red. The new species are discussed in relation to their congeners, and a distribution map is provided. PMID- 27701274 TI - Prosorhynchus Odhner, 1905 (Digenea: Bucephalidae) from the orange-spotted grouper Epinephelus coioides (Hamilton, 1822) (Epinephelidae), including Prosorhynchus tonkinensis n. sp., from the Gulf of Tonkin, Vietnam. AB - A total of 169 specimens of the orange-spotted grouper Epinephelus coioides (Hamilton) were collected from fishermen and marine fish farms in the Gulf of Tonkin, Vietnam. Five different species of Prosorhynchus Odhner, 1905 were recorded, including P. tonkinensis n. sp. The new species differs from all other Prosorhynchus species in the presence of an indented posterior extremity. It can be distinguished from the most closely related P. atlanticus Manter, 1940 and P. crucibulum Rudolphi, 1819 by the extension of the uterus always to the level of the ovary, the width and premouth distance in the former, and the arched vitellarium and smaller egg size in the latter, and a different host and geographical region. Prosorhynchus sp. A (not fully identified in this study) has been earlier reported from E. coioides from New Caledonia (see Prosorhynchus sp. B of Bray and Justine, 2013), P. luzonicus Velasquez, 1959 is reported throughout South-East Asia, and Prosorhynchus sp. B (no further identification possible based on a single specimen in this study) and P. maternus Bray & Justine, 2006 are reported for the first time from Vietnam. The present study demonstrates a close relationship of the Prosorhynchus species composition in Vietnam with the Indo-Australian region, warranting further comparative studies among the different epinephelids. PMID- 27701276 TI - Two new species of Caenis Stephens, 1835 (Ephemeroptera: Caenidae) from South America. AB - Caenis Stephens, 1835 is a relatively diverse South American genus of Caenidae (Ephemeroptera), with 22 recorded species, but much of its diversity remains poorly explored in this region. In the present study, two new species of Caenis with apically pointed forceps are described: Caenis amacayacu sp. nov., based on male adults from Colombia; and C. elidioi sp. nov, based on all life stages from several localities in Brazil. PMID- 27701277 TI - The first Turcolana Argano & Pesce, 1980 (Isopoda: Cirolanidae) from the Greek mainland. AB - Turcolana Argano & Pesce, 1980 is the isopod genus occurring in freshwater and brackish groundwater environments around the eastern Mediterranean. In this study, a revised diagnosis of the genus, an updated map of species distribution and a key to species are presented. The first cave dwelling species is described from the Melissotrypa Cave in central Greece, a highly troglomorphic Turcolana lepturoides sp. nov. Its principal distinguishing characters are elongated appendages: styliform uropods (twice as long as pleotelson), antennae (half as long as body) and pereopods (e.g. pereopod 7 45% as long as body). Mitochondrial DNA sequences (16S rRNA, 12S rRNA) of the new species are provided. PMID- 27701279 TI - Review of the genus Defilippia Lioy (Bombyliidae, Diptera) from Egypt, with description of a new species, new combinations, and a neotype designation for D. pharaonis (Paramonov, 1928). AB - In the present study, five Defilippia species are shown to be represented in Egypt. Two species, D. efflatouni (Bezzi) and D. minos (Meigen), were already included in Defilippia; two species, D. decrepita (Wiedemann), comb. nov., and D. pharaonis (Paramonov), comb. nov., are newly combined to Defilippia; and a new species, D. elbayensis, sp. nov., is described herein. Homeotypes of Exoprosopa flava Paramonov, 1928 and Defilippia decrepita (Wiedemann, 1828), comb. nov. have been examined and it was found that the two species are not synonymous and Exoprosopa flava Paramonov, 1928, stat. rev. is rather a distinct valid species in its original genus Exoprosopa. A neotype for D. pharaonis (Paramonov, 1928) is designated. PMID- 27701278 TI - Cathorops festae (Boulenger 1898) (Siluriformes; Ariidae), a valid species from Ecuador and Peru. AB - Over the past decade, the Sea Catfish (Ariidae) genus Cathorops has been the focus of a major taxonomic review, which has resulted in the revalidation of five synonymized nominal species, and the recognition of seven new species. With 21 valid species, Cathorops is currently the most species-rich genus of Ariidae in the New World. The principal lacuna in the taxonomic knowledge of genus species is the uncertain status of Arius festae Boulenger, 1898, described from Naranjal, in the Guayas River basin of Ecuador. In the present study Cathorops festae is redescribed as a valid species based on morphological and molecular data. PMID- 27701280 TI - Descriptions, transference and new records of Lamiinae from Central and South America (Coleoptera, Cerambycidae).

Psapharochrus alboguttatus (Melzer, 1935) is transferred to Alphus White, 1855. New country, department and state records are provided in Lamiinae. PMID- 27701281 TI - The systematic position of Hypsugo macrotis (Chiroptera: Vespertilionidae) and a new record from Peninsular Malaysia. AB - The Southeast Asian species of Hypsugo are rare bats, except for H. cadornae and H. pulveratus, which are distributed throughout the Indomalayan region. Hypsugo macrotis is restricted to Peninsular Malaysia, Sumatra, Java and adjacent islands, and is known only from a handful of specimens. Here we report a new locality record of the species from Seremban, Peninsular Malaysia, which also represents the first known building-dweller colony of any Hypsugo from the region. We discuss the taxonomic status of two morphologically similar species, H. macrotis and H. vordermanni, and provide the first COI and cyt b gene sequences for H. macrotis and reconstruct the species' phylogenetic relationships. PMID- 27701282 TI - Two new species of gill parasites assigned to Protoancylodiscoides (Monogenea, Ancyrocephalidae) from Chrysichthys spp. (Siluriformes, Claroteidae) in River Sanaga (Cameroon). AB - Host specimens were sampled in the middle course of the River Sanaga (Cameroon) from January to October 2014. Two new species, Protoancylodiscoides auratum n. sp. from Chrysichthys auratus and Protoancylodiscoides combesi n. sp. from C. auratus, Chrysichthys nigrodigitatus and Chrysichthys longidorsalis, are herein described. These new helminths differ from the congeneric species by the size of the haptoral sclerites, the male copulatory organ length, the diameter and morphology of the vagina. At this stage, the present study suggests that Protoancylodiscoides auratum is oioxenous, while P. combesi is stenoxenous. The two new Protoancylodiscoides species bring to three the number of those parasitizing C. auratus, and to four the number of those described from Chrysichthys spp. PMID- 27701283 TI - A remarkable new species of winter stonefly (Plecoptera: Capniidae) from Southeastern China.

PMID- 27701285 TI - Species of braconid wasps described by Christian Godfried Nees ab Esenbeck in 1811, 1812, 1816, 1818, 1834. A revisionary checklist (Hymenoptera, Braconidae). AB - In his five publications Nees (1811-1834) described 263 braconid species originating mainly from Germany and, less in number, from a further seven countries in Europe. The braconid species were assigned to 19 genera: twelve have been created by him and the rest (seven genera) by three other authors. The majority of the species (218) remained valid, the rest of the names (45) were placed in synonymy (by other authors). By his descriptions the species and genera are more or less recognizable, nevertheless their redescriptions are promoting their unambiguous recognition. In the first checklist provided, the genera and species are presented following Nees's original denominations and the current valid generic and species names are listed (denoted by an equals (=) sign). In the second checklist, the current valid generic and species names are compared with the original generic and species names. In the third checklist, the braconid species of 16 other authors included in Nees five publications are listed. New author's names for three species are provided: Doryctes leucogaster Ziegler, 1834 (Bacon), Microgaster nigricans Gyllenhal, 1834 and Microplitis sordipes (Ziegler, 1834) (Microgaster); the author of these three species was Nees. The Nees Collection (braconid and other material) was destroyed at the end of the Second World War. PMID- 27701286 TI - A systematic revision of the genus Gnophopsodos Wehrli, 1945, with description of two new species (Lepidoptera: Geometridae). AB - In a comprehensive morphological study besides results of DNA barcoding the genus Gnophopsodos Wehrli, 1945 is taxonomically revised. The taxon comprises nine species. Diagnostic characters are depicted and a key to the species based on the morphology of male genitalia is provided. Males and females (if available) of each species and their genitalia are illustrated. The distribution of all species is described and figured on maps. Gnophopsodos hilmari spec. nov. from Uzbekistan and Kyrgyzstan, Gnophopsodos sabine spec. nov. and Gnophopsodos ravistriolaria pantherinus subspec. nov., both from the Russian part of the Altai Mountains, are described as new. Gnophopsodos puengeleri (Bohatsch, 1910) stat. rev. is re established as a separate species. The following synonyms are recognized: Chelegnophos Wehrli, 1951 syn. nov. of Gnophopsodos Wehrli, 1945; Chelegnophos alaianus Viidalepp, 1988 syn. nov. of Gnophopsodos puengeleri (Bohatsch, 1910), Psodos altissimaria Oberthur, 1913 syn. nov. of Gnophopsodos gnophosaria (Oberthur, 1893), and Gnophos orbicularia Pungeler, 1904 syn. nov. of Gnophopsodos stemmataria (Eversmann, 1848) comb. nov. The latter is transferred from the genus Gnophos Treitschke, 1825 to the genus Gnophopsodos. PMID- 27701287 TI - Immature stages and larval chaetotaxy of Notofairchildia stenygros (Quate & Alexander) (Diptera: Psychodidae: Bruchomyiinae). AB - Some authors have hypothesized that Bruchomyiinae is "the most plesiomorphic subfamily of Psychodidae" and its members "are among the most primitive living Diptera". Although Bruchomyiinae is of no medical importance, it is of great evolutionary significance, having long been placed as the sister group of Phlebotominae. In general, species of this subfamily are rarely collected in their natural environment; therefore, adults and, even more so, the immature stages of these flies are poorly known. We describe the egg, larvae and pupae of Notofairchildia stenygros and provide nomenclatural notes on larval chaetotaxy based on analyses using scanning electron microscopy (SEM) and optic microscopy. The morphology of immature Nt. stenygros is compared with other Bruchomyiinae and Psychodidae species, especially with species of Phlebotominae that are superficially similar to Bruchomyiinae. Results of this study revealed striking morphological differences between the immature stages of Bruchomyiinae and Phlebotominae; the former are lacking abdominal pseudopods and microtrichia on the cephalic integument, both of which are present in the larvae of Phlebotominae. These morphological differences observed in the immature stages between members of the two subfamilies support the findings of recent molecular studies indicating that Bruchomyiinae and Phlebtominae are evolutionarily not closely related. Notofairchildia stenygros is now the fourth species of Bruchomyiinae for which the immature stages are described. PMID- 27701288 TI - A new species of salamander of the genus Hynobius (Amphibia, Caudata, Hynobiidae) from South Korea. AB - We describe a new species of lentic-breeding Hynobius salamander from the Naro Islands, near the village of Bongrae-myeon, Goheung-gun, Jeollanam-do, South Korea, on the basis of results of morphological, ecological and genetic analyses. Hynobius unisacculus sp. nov. is distinguished from its congeners by a combination of the following morphological attributes: (1) comparatively small size (adult SVL up to 61 mm; range 38.3-60.3 mm in males and 37.5-59.9 mm in females); (2) relatively slender short limbs; tips of fore- and hindlimbs adpressed on body never meeting, but separated by a large gap (gap of -3.0 to 1.5 costal folds in males and -3.5 to -1.5 in females); (3) comparatively short tail (TL/SVL ratio in adult males varying from 0.54-0.98, in adult females from 0.55 to 0.89), tail flattened and with a low dorsal fin extending to the posterior one-third of tail length; (4) usually 11 (occasionally 12) costal grooves; (5) in adults, dark brown dorsum with indistinct bronze or dark copper spots, lighter greyish-white or pinkish belly; (6) well developed fifth toe; (7) comparatively shallow vomerine tooth series with 13-23 vomerine teeth; (8) small, pigmented ova, located in one, occasionally two, strings in a small, curved egg sac with folded envelope, lacking distinct mucous stalks or whiptail-like structures on both ends. The molecular differentiation among Korean Hynobius is high; Hynobius unisacculus sp. nov. is genetically highly divergent from the morphologically similar H. leechii, H. yangi and H. quelpaertensis: pairwise distances are 9.7%, 9.1% and 8.0% of sequence divergence at the COI mtDNA gene respectively, and 10.9%, 10.9% and 9.4% of sequence divergence at the cyt b mtDNA gene, respectively. At present, the new species is known from coastal areas and offshore islands in southeastern part of Jeollanam-do in South Korea. We suggest the species should be considered as Vulnerable (Vu2a) in accordance with IUCN's Red List categories. Our study supports the presence of undiagnosed taxonomic diversity among Korean Hynobius.

AB - The ground beetle genus Hexachaetus Chaudoir, 1871 is re-defined and reviewed. Bearing six setae on ligula is no more considered as a crucial characteristic for Hexachaetus. Members of Hexachaetus share the following combination of morphological features: body polish, smooth, and impunctate, ligula more or less dilated at apex, bearing 4, 6, or even 12 setae apically, prosternal process unbordered at apex, elytra distinctly and obliquely truncated at apex, with the apical inner angles very sharp in most species (except for H. mulan n. sp.), and interval 3 with anterior and posterior setiferous pores (median one lacking). The members of Hexachaetus are about 20 species which could be divided into six species groups. All except angulatus species group are dealt with in this paper, with descriptions of four new species: H. kirschenhoferi n. sp. (Indonesia: Kalimantan), H. brunki n. sp. (Malaysia: N. Borneo), H. vietnamensis n. sp. (Vietnam: Annam) and H. mulan n. sp. (Malaysia: Perak and Pahang). H. maindroni Tian & Deuve, 2006 is proposed as a subspecies of H. lateralis Guerin, 1843, n. stat. A key to species groups and species of the genus is also provided. PMID- 27701290 TI - Three new brackish-water thalassocypridine species (Crustacea: Ostracoda: Paracyprididae) from the Ryukyu Islands, southwestern Japan. AB - We describe three new species of brackish-water ostracods representing two genera in the ostracod tribe Thalassocypridini from mangrove forests in the Ryukyu Islands, subtropical southwestern Japan, and provide their barcoding sequences for the mitochondrial cytochrome c oxidase subunit I (COI) gene. Mangalocypria ryukyuensis sp. nov. was found on Okinawa Island. We also found a Mangalocypria population on Ishigaki Island that was morphologically identical to M. ryukyuensis on Okinawa, but an individual differed by 4.7% in COI sequence (K2P distance) from an individual from Okinawa. This is the first record for Japan of a species in Mangalocypria. Paracypria longiseta sp. nov., obtained from Okinawa Island, is similar to Pontoparta hartmanni. Paracypria plumosa sp. nov. from Ishigaki Island is similar to Pa. adnata described from Yakushima Island, Japan. The COI genetic distance between individuals of Pa. longiseta and Pa. plumosa was roughly as large as that between either of these species and individuals in the Mangalocypria populations. Our study underscores that genera in Thalassocypridini may not represent natural groups, and that this tribe needs taxonomic revision. PMID- 27701292 TI - Larva of Glyptotendipes (Glyptotendipes) glaucus (Meigen 1818) (Chironomidae, Diptera)-morphology by Scanning Electron Microscope (SEM), karyotype, and biology in laboratory conditions. AB - Larvae belonging to the family Chironomidae are difficult to identify. The aim of the present study was to describe the larval morphology of G. (G.) glaucus with the aid of a Scanning Electron Microscope (SEM), the karyotype and biology based on materials obtained from laboratory culture. Describing the morphology of larvae, special attention was paid to rarely or never described structures like the maxilla (lacinia and maxillary palp), the long plate situated below the ventromental plate, and plate X situated between lacinia and mentum. The use of SEM allowed also to obtain better images of labrum and ventromental plate. Morphological features of this species have been supplemented by karyotype and biology of larvae in laboratory conditions. Under controlled experimental conditions we found non-synchronous development of G. (G.) glaucus larvae hatched from one egg mass reflected in different lengths of larvae and emerged imagoes.

The new species is compared with the allopatric C. aliena (Faust, 1890) differing in size, shape of scales, scale patch close to the scutellum, size of mucrones on the meso- and metatibiae, and also shape of the apex of the penis. Controversy over the number of segments in the antennae in the genus Corimalia is summarized. An annotated catalogue and key of all Corimaliini species in the Caucasus is provided. PMID- 27701294 TI - Patterns of ecology and distribution of the tree crickets Oecanthus dulcisonans and O. pellucens (Orthoptera: Gryllidae; Oecanthinae) in southern Italy. AB - Ecological proclivities of the tree cricket Oecanthus dulcisonans, which has been recently separated from the well known O. pellucens, have been poorly investigated. Moreover, studies on the patterns driving niche segregation between these related species are still needed. This study aims to explore the role of macro-habitat in shaping the distribution of O. dulcisonans and O. pellucens in southern Italy. Occurrence data were sampled by means of a rapid acoustic survey scheme at a regional scale. The significance of difference in ecological and habitat parameters was tested between the two species. While confirming species behavioural patterns, new findings are provided with regard to their ecological difference. Species distribution proves to be primarily driven by elevation gradient and temperature variation, with O. dulcisonans common and widespread in warmer lowlands and O. pellucens limited to higher altitudes. The two species also show significant spatial segregation within vegetation layers. These findings also provide cues for future studies on species interaction, as well as for the assessment of a monitoring scheme which may help interpreting the effects of broad environmental changes. PMID- 27701295 TI - Sangpradubina, an astonishing new mayfly genus from Thailand (Ephemeroptera: Leptophlebiidae: Atalophlebiinae). AB - A newly discovered representative of Leptophlebiidae is described and illustrated from Thailand as Sangpradubina thailandica, gen. nov. and sp. nov., based on larvae and reared adults. This new species presents an interesting transitional position, being close to Choroterpes s.l. in the winged stages, but closer to Thraulus s.l. in the nymphal stage. Nymphs are differentiated from those of all genera of the Thraulus lineage by the combination of gill I consisting of only a single and slender lamella, gills II-VII being fimbriate only in the distal half, each mandible having a tuft of setae only in the middle of the lateral margin, each maxilla having a well-developed anterolateral projection, fore- and middle femora each having a row of long setae on the outer margin, as well as tarsal claws having 4 denticles at the base and 9 in the apical position. Adults of the new genus barely differ from any genera of the Choroterpes lineage. The egg chorionic structure of Sangpradubina also appears to be unusual in that KCT's are concentrated on one pole.

AB - The Central American tribe Neaenini, originally comprising only the monobasic genus Neaenus Fowler, was thought to be transitional between Cercopinae and Aphrophorinae. The genus is here enlarged by 5 (1 unnamed) additional species including 2 in a distinctive new subgenus Neaniskus. Keys are presented to 5 species of Neaenus, to 12 allied Neotropical genera and their 57 species: 12 of Tomaspisinella Lallemand, 1927 (=Hemitomaspis Lallemand, 1949, syn.nov. and 3 distinctive new subgenera Meretricula, Merinx and Merulatomus), 14 species of Microsargane Fowler, 1897 (=Ecothera Melichar, 1915, syn.nov., with 2 distinctive new subgenera Microrhaphe and Microtholia) and 31 species of Zuata Fennah, together with 2 species of Helioptera gen. nov. and 6 monobasic genera (Liparonotum gen. nov., Marcion Fennah, Menytes gen. nov., Microclimax gen. nov., Microlaqueus gen. nov. and Simorhina Jacobi). The small Neotropical genera Tomaspisina Distant and Olcotomaspis Lallemand (with 2 new combinations and subgenus Hyalotomaspis Lallemand, stat.nov.) appear to be allied to the large old world genus Phymatostetha Stal rather than to any new-world Cercopinae. A check list is presented to these 13 genera and their 76 species (of which 30 are new to science and 5 of Zuata are new synonyms). Males are described for 5 species previously known from females but males of 9 (in 6 genera) are still unknown. Male genitalia define a new tribe of Cercopinae, Microsarganini (Microsargane was formerly placed in Aphrophorinae) that also includes Liparonotum, Microclimax and Microlaqueus. Almost half of the genera are monobasic without synapomorphies to Aphrophorinae, suggesting that these genera (including several genera resembling both Aphrophorinae and Cercopinae) represent relict lineages at the base of the subfamily Cercopinae. PMID- 27701298 TI - Taxonomy of the Mexican species of Thyreocephalus Guerin-Meneville Coleoptera: Staphylinidae, Xantholinini). AB - Mexican species of Thyreocephalus were analyzed taxonomically based on review of 125 specimens in eight entomological collections. We propose that T. dugesi (Casey, 1906) could be a junior synonym of T. scutellaris (Sharp, 1885), but refrain from formal changes until the types can be examined. Thyreocephalus arizonicus Smetana, 1982 is recorded for the first time from Mexico in the states of Estado de Mexico, Jalisco and Morelos. Currently nine species are recorded from Mexico, which is the most species-rich country on the American continent. Five closely related species are included in the "puncticeps" species group recognized and proposed here. A key for species, supported with illustrations of the principal diagnostic structures is provided, as well as redescriptions or diagnoses, and taxonomic discussions for each species. Recognized distribution patterns are briefly discussed. PMID- 27701299 TI - Two new and one redescribed species of Acanthobothrium (Cestoda: Onchoproteocephalidea: Onchobothriidae) from Dasyatis akajei (Myliobatiformes: Dasyatidae) in the China Sea. AB - Acanthobothrium ningdense n. sp. and Acanthobothrium guanghaiense n. sp. are described from the spiral intestine of the whip stingray, Dasyatis akajei (Muller & Henle). Acanthobothrium ningdense n. sp. is reported based on 38 cestode specimens collected at five locations along the Chinese coast, i.e. Taizhou, Zhejiang Province, Ningde and Xiamen, Fujian Province, Taishan, Guangdong Province and Sanya, Hainan Province between 2012 and 2015. Acanthobothrium ningdense n. sp. belongs to the "species category 4" characterised by Ghoshroy & Caira. Among category 4 Acanthobothrium species, A. ningdense n. sp. most closely resembles A. micracantha Yamaguti, 1952 and A. latum Yamaguti, 1952, both from the same host species. Acanthobothrium ningdense n. sp. differs from A. micracantha by lacking a long robust hook handle that connects the bases of medial and lateral hooks, and from A. latum by having much longer axial prongs than abaxial prongs. Acanthobothrium guanghaiense n. sp., only found in Taishan, Guangdong Province in 2014, is a category 2 Acanthobothrium species. Among category 2, A. guanghaiense n. sp. most closely resembles A. semnovesiculum Verma, 1928, but can be differentiated from it by the arrangement of testes (in two staggered columns rather than in two tandem columns), and the shape of abaxial prong (nearly straight instead of with a conspicuous curve in the proximal portion). Acanthobothrium macrocephalum Wang & Yang, 2001 is redescribed based on new specimens collected from D. akajei in Guanghai and Sanya. With this study, the total number of Acanthobothrium species reported from D. akajei is brought to nine. It is possible that some of the species of Acanthobothrium previously reported from D. akajei not encountered in this study may have geographically restricted distributions, as was observed here for A. guanghaiense n. sp..

AB - The current knowledge of the Collembolan fauna of Thailand is reported here, based on the checklist of Bedos (1994) completed by data on several taxa described since this date, with an update of the taxonomic status of the species. A total of 194 species from 53 genera and 14 families are listed, that were mostly discovered and described during the last three decades. The updated checklist illustrates a strong unevenness in sampling efforts across space and habitats, and in the degree of taxonomic coverage of the different families of the group. Geographically, only the Doi Inthanon massif can be considered as relatively well known, but even there the species in several major habitats and microhabitats have not been sampled. Data are lacking or much more limited for all other regions of the country. The species richness of Thailand is undoubtedly much more than observed number.

Three of them are described as new: N. gutianensis Hu & Li, sp. n., N. zhaotiexiongi Hu & Li, sp. n., and N. zhangsujiongi Hu & Li, sp. n. Two synonymies are proposed: N. minor Koch, 1939 = N. nigritulus Hu, Li & Zhao, 2011, syn. n.; N. chinensis Koch, 1939 = N. tianmuensis Hu, Li & Zhao, 2011, syn. n.

AB - Acasta sulcata spinosa Daniel, 1955 has been discovered to be a junior homonym of Acasta spinosa Hiro, 1939. As both names were originally described in the genus Acasta, ICZN (International Commission on Zoological Nomenclature) Article 57.2 defines A. sulcata spinosa as a primary junior homonym, even though it is of subspecific nature. PMID- 27701303 TI - On the authorship of Austromegabalanus psittacus (Molina). AB - Austromegabalanus psittacus is a large, common and economically important shoreline barnacle species of the west coast of South America. It was originally described by Juan Ignacio Molina as Lepas psittacus, but some confusion has arisen as to the exact reference to and year of publication of this species. PMID- 27701304 TI - A new synonymy in the genus Macrocixius (Hemiptera: Fulgoromorpha: Cixiidae). AB - Until recently the genus Macrocixius Matsumura, 1914 (Hemiptera: Fulgoromorpha: Cixiidae) contained two species: M. giganteus Matsumura, 1914 (the type species) and M. grossus Tsaur & Hsu, 1991. Two recent papers revised the genus within a short interval of time. Both Zhang & Chen (2013) and Orosz (2013) provided redescriptions of the genus and its two previously included species; Zhang & Chen (2013) described two new species from China; Orosz (2013) described five new species from Nepal, Taiwan, Vietnam, and Indonesia. PMID- 27701305 TI - First Jurassic grasshopper (Insecta, Caelifera) from China. AB - Orthoptera is divided into two suborders, the Ensifera (katydids, crickets and mole crickets) and the Caelifera (grasshoppers and pygmy mole crickets). The earliest definitive caeliferans are those found in the Triassic (Bethoux & Ross 2005). The extinct caeliferan families, such as Locustopsidae and Locustavidae, may prove to be stem groups to some of the modern superfamilies (Grimaldi & Engel 2005). Locustopsidae is known from the Late Triassic or Early Jurassic to Late Cretaceous, consisting of two subfamilies (Gorochov et al. 2006). They are recorded from Europe, England, Russia, central Asia, China, Egypt, North America, Brazil and Australia. Up to now, Late Mesozoic fossil deposits of China has been reported plenty taxa of orthopterids, e.g. ensiferans, phasmatodeans, grylloblattids (Cui et al. 2012; Gu et al. 2010; Gu et al. 2012a; Gu et al. 2012b; Ren et al. 2012; Wang et al. 2014); but, with few caeliferans records, only four species, Pseudoacrida costata Lin 1982, Mesolocustopsis sinica Hong 1990, Tachacris stenosis Lin 1977 and T. turgis Lin 1980, were reported from the Early Cretaceous of Ningxia, Shandong, Yunnan and Zhejiang of China.

PMID- 27701308 TI - Lithobius (Ezembius) multispinipes n. sp., a new species of centipede from NorthWest China (Lithobiomorpha: Lithobiidae). AB - The centipede subgenus Lithobius (Ezembius) Chamberlin, 1919 comprises a group of about 60 species known from the Near East across Siberia and Central Asia to China, and Japan, and Southwards into the Northern Indian subcontinent and the Northern part of the Oriental region (Eason 1992, Zapparoli 1999). It is also known from Alaska in Western North America (Zapparoli & Edgecombe 2011). Although the subgenus was formally proposed as new and described in 1923 (Chamberlin 1923), according to Jeekel (2005) its name had been already validated in 1919 (Chamberlin 1919). Ezembius is characterized by the presence of 2+2 or 3+3 coxosternal teeth, antennal articles fixed at 20 or thereabouts, tergites generally without posterior triangular projections and tarsal articulation of legs 1-13 distinct (Chamberlin 1923, Zapparoli & Edgecombe 2011).

AB - A new tribe Labiobaetini tribus n. is established for a plesiomorphon Labiobaetis Novikova & Kluge 1987 and a holophyletic taxon Pseudopannota Waltz & McCafferty 1987. New synonymy Pseudopannota Waltz & McCafferty 1987 = Ophelmatostoma Waltz & McCafferty 1987, syn. n. is proposed. A new species Pseudopannota pannota sp. n. closely related to P. berthrandi (Demoulin 1967) is described from Zambia based on imagoes of both sexes reared from larvae. Pseudopannota camerunense (Ulmer 1920) comb. n. is redescribed from Zambia based on imagoes of both sexes reared from larvae. A new species Pseudopannota fusca sp. n. is described from Uganda based on larvae and subimagoes of both sexes extracted from mature larvae. Pseudopannota maculosa (Crass 1947) is reported from Zambia based on larvae. Labiobaetis tenuicrinitus (Kopelke 1980) comb. n. (= Baetis spatulatus Gillies 1994 syn. n.) is redescribed from Uganda based on imagoes of both sexes reared from larvae. PMID- 27701310 TI - On the genus Aphaobius Abeille de Perrin, 1878, with description of a new species from the mesovoid shallow substratum (MSS) of Austria (Coleoptera: Leiodidae: Cholevinae: Leptodirini). AB - Aphaobius haraldi sp. n. from the mesovoid shallow substratum (MSS) of the Austrian Alps is described, illustrated, and compared with the closest species of the genus. The new species belongs to the A. kraussi species group, formerly including five species. It can be readily separated from other species of the genus by the large parameres, with an enlarged apical part, a unique feature among species of Aphaobius. The phylogenetic position of the new species is clarified using mitochondrial and nuclear data of four related species of Aphaobius, plus some representatives of related genera from the same geographic area. The diversification of the group was estimated to be recent, dating from the Pleistocene. New records and molecular data are provided regarding the enigmatic monospecific genus of the Austrian Alps, Lotharia Mandl, 1944, which was found to be sister to the studied species of Aphaobius. PMID- 27701311 TI - One new genus and three new species of plumulariid hydroids (Cnidaria, Hydrozoa, Plumulariidae) from the western Pacific Ocean, with a re-examination of Plumularia insignis Allman, 1883 and related taxa. AB - One new genus (Schizoplumularia) and three new species (Schizoplumularia vervoorti, S. geniculata and S. elegans) of plumulariids are recognized and described from large collections of plumularioid hydroids collected in New Caledonia and vicinity during several French expeditions. During taxonomic studies of these hydroids, colonies were compared with type material of Plumularia insignis Allman, 1883 and several other similar species-group taxa. As a result, three of the latter (P. flabellum Allman, 1883, P. conjuncta Billard, 1913, and P. billardi nom. nov.) are recognized as valid in addition to P. insignis. The binomen P. billardi is a replacement name for P. insignis var. gracilis Billard, 1913. In being elevated to the rank of species in this work, it becomes an invalid junior primary homonym of several others having the same name. PMID- 27701312 TI - Revision of the Ambrysus hybridus Montandon species complex (Heteroptera: Naucoridae: Cryphocricinae) with the description of a new species from Mexico. AB - The Ambrysus hybridus Montandon species complex is revised and includes A. convexus Usinger, A. fuscus Usinger stat. rev., A. hybridus Montandon, A. lattini La Rivers, A. plautus Polhemus & Polhemus, A. spiculus Polhemus & Polhemus, A. thermarum La Rivers, and A. ultimus La Rivers. Ambrysus lariversi n. sp. is the ninth species in this complex and is described from Mexico. A. tridentatus La Rivers and A. woodburyi Usinger are proposed as junior synonyms of A. hybridus Montandon and for which a lectotype is designated. Most of the species in this complex occur only in Mexico, although A. thermarum is known only from the United States and A. hybridus occurs from the southwestern United States to southern Mexico and has the widest distribution of any species in this complex. Features uniting these species are related to male genitalia and structures associated with the male and female genitalia. PMID- 27701313 TI - A review of the genus Garra Hamilton 1822 of Bhutan, including the descriptions of two new species and three additional records (Cypriniformes: Cyprinidae). AB - Seven species of Garra are herein accounted for in Bhutan. Three new records of known species, G. arupi, G. birostris, and G. lissorhynchus, and two new species, G. bimaculacauda sp. nov. and G. parastenorhynchus sp. nov., are reported from central and southern Bhutan. Garra bimaculacauda sp. nov. is most notably different from its congeners by the presence of two dark spots on the lobes of the caudal fin, having one spot on each lobe. Meristic and morphometric differences from northeastern Indian congeners exist as well. Garra parastenorhynchus sp. nov. is differentiated from its congeners by the presence of a prominent, overhanging, club-shaped proboscis, and a suite of meristic and morphometric characters. Notes on the taxonomy are provided for some species. Notes are provided on the biology and ecology for most species, which have been inferred from field observations. Ranges are expanded for two recently described taxa from Northeast India G. arupi, and G. birostris. A key is provided to the currently known species of Garra within Bhutan.

This new species can be distinguished from the other congeners by the presence of spinulation on the lateral margins of uropod I rami, row of small robust setae on uropod II ramus, and single robust seta on uropod III ramus. More detailed distinguishing characters from R. albomaculosus are also discussed. This is the first record of the genus Rhinoecetes from Japan. Key to all the species of Rhinoecetes is provided. PMID- 27701316 TI - A new species of lizard Placosoma Tschudi, 1847 (Squamata: Gymnophthalmidae) from the relictual forest mountains of the State of Ceara, Brazil. AB - A new species of Placosoma Tschudi, 1847, until now restricted to the Atlantic Forest areas of southeastern Brazil is described based on specimens obtained about 1700 km north to the current distribution of the genus. Placosoma limaverdorum spec. nov. is apparently endemic to three "brejos-de-altitude", relictual forest mountains surrounded by dry Caatingas, in the State of Ceara, northeastern Brazil. It differs from their congeners by the presence of an undivided transparent palpebral disk, a divided nasal scale with a central nostril, a deep tympanic recess, a distinctive and thin light vertebral stripe on the dorsal surface of the head, body and tail, femoral pores present only in males (21-26), preanal pores absent and additionally by having 21-24 rows of transverse ventral scales, 34-38 dorsals, dorsal, lateral and ventral scales smooth, dorsal scales quadrangular, longer than wide, except in the neck region, where they are wider than long.

PMID- 27701323 TI - Onuphis and Mooreonuphis (Annelida: Onuphidae) from West Africa with the description of three new species and the reinstatement of O. landanaensis Augener, 1918. AB - The taxonomy of eastern Atlantic species of the genus Onuphis has been confused due to the somewhat cursory and misleading descriptions of species and the disregard of the true identity of the type species of the genus, O. eremita, which has been commonly reported from West Africa, along with O. geophiliformis and O. rullieriana. However, all three species are now considered as unlikely to occur in western Africa. This work recognises three species of Onuphis from this region. Two of them, Onuphis augeneri sp. nov. and O. hanneloreae sp. nov., are newly described from Nyanga estuary (Gabon) and Sal Island (Cape Verde) respectively. Furthermore, Onuphis landanaensis, a species described from the Gulf of Guinea and subsequently synonymised with O. eremita, is formally reinstated and redescribed based upon the re-examination of the original types. Detailed descriptions and illustrations of all species are presented as well as the ontogenetic changes of the brooder O. hanneloreae sp. nov. Furthermore, the genus Mooreonuphis is recorded for the first time in Africa with the description of M. nunezi sp. nov. from Cape Verde archipelago. Additionally, a dichotomous key to all species of the genera Onuphis and Mooreonuphis from the eastern Atlantic is included. PMID- 27701324 TI - Cladorhiza corallophila sp. nov., a new carnivorous sponge (Cladorhizidae, Demospongiae) living in close association with Lophelia pertusa and Madrepora oculata (Scleractinia). AB - In this study, we describe a new species of cladorhizid sponge, which shows a very peculiar mode of life: It always occurs in association with the scleractinian cold-water corals Lophelia pertusa and Madrepora oculata. Although the sponge lives in nutrient-rich areas, we document its carnivorous feeding behavior. The identity of the new species was verified using molecular markers: the species is very closely related to the North-Atlantic Cladorhiza abyssicola, but it differs distinctly, and forms a monophyletic clade. The two species might be considered very close relatives, probably sister species deriving from a common ancestor. PMID- 27701326 TI - Description of two new species of Seinura Fuchs, 1931 (Nematoda: Aphelenchoididae) from Iran. AB - Two new species of Seinura are described and illustrated using both morphological and molecular characters. Seinura persica n. sp. is characterized by having females with a distinct cephalic region, stylet 19.5 (18-20) MUm long, four incisures in the lateral fields, position of excretory pore anterior to the base of metacorpus, post-uterine sac 54.8 (50-60) MUm long, and an elongate-conoid tail with a shallow depression on the dorsal side ending in a sharply pointed tip. Males have body length of 467 and 592 MUm, spicules 15 and 16 MUm long with a prominent triangular-shaped rostrum, developed condylus and no cucullus. Seinura hyrcania n. sp. is characterized by having an offset lip region, stylet 21.5 (18-24) MUm long, three incisures in the lateral fields, excretory pore anterior to the base of the metacorpus, post-uterine sac 19 (12-25) MUm long and conical tail ending in a filiform terminus. Morphological and morphometric diagnostic characters together with molecular data based on partial sequences of SSU and LSU of the ribosomal DNA gene are provided for these new species.

AB - The colonial peritrich ciliate Epistylis anastatica (Linnaeus, 1767) was discovered living as an epibiont on Mesocyclops isabellae Dussart & Fernando, 1988 collected from a pond in Andhra Pradesh state, India. This is the first report of Epistylis on this host, and a description of its morphological characteristics is provided. The biomass of colonies of E. anastatica relative to that of their hosts was relatively high, being greater than that of the host in some cases (8.11 mm3 vs. 1.14 mm3 or less), and this epibiotic burden has the potential to have an impact on the host's activities. Relationships between epibiotic peritrichs and microcrustaceans like cyclopoid copepods may be much more complex than previously supposed and merit more thorough investigation. Species of Epistylis are commonly found on cyclopoid copepods, but resources for taxonomic identification are limited and scattered; therefore, an annotated checklist of all species reported from cyclopoid copepods and a summary of the diagnostic characteristics of each one is provided as an aid to investigators. Some records of Epistylis spp. from cyclopoid copepods that are accompanied by documentary evidence are misidentifications, raising the suspicion that many other undocumented records also may be erroneous; therefore, it is suggested that authors provide supplementary descriptions and figures.

PMID- 27701328 TI - Comments on the morphology and biology of Pammene castanicola Trematerra & Clausi, 2009 (Lepidoptera: Tortricidae: Grapholitini). AB - Many insects are reported to damage cultivated chestnut (Castanea sativa Mill.; Fagaceae) in Italy, but the most important pests of chestnut fruits are weevils (Curculio elephas Gyll. and Curculio glandium Marsh.; Curculionidae) and tortricid moths (Pammene and Cydia; Tortricidae) (Pollini, 1998, Speranza, 1999). The larvae of the tortricid pests develop internally, tunnelling in the fruits and eating the endocarp (Rotundo et al. 1991), which significantly reduces nut quality and commercial value. The most damaging tortricid moths in the Italian chestnut industry are Pammene fasciana (Linnaeus) (the early chestnut moth), Cydia fagiglandana (Zeller) (the intermediate chestnut moth), and Cydia splendana (Hubner) (the late chestnut moth) (Pedrazzoli et al. 2012). Pammene castanicola Trematerra & Clausi, 2009 was recently described from chestnut woods near Etna Vulcan, Sicily (Trematerra and Clausi 2009), and it is known only from the vicinity of the type locality. It is similar to Pammene fasciana in morphological and biological features, and it was previously misidentified as P. fasciana.

AB - The genus Tibicen has had a confusing history (see summary in Boulard and Puissant 2014; Marshall and Hill 2014; Sanborn 2014). Boulard and his colleague (Boulard 1984; 1988; 1997; 2001; 2003; Boulard and Puissant 2013; 2014; 2015) have argued for the suppression of Tibicen and the taxa derivatived from it in favor of Lyristes Horvath. Boulard's argument for suppression was first described in Melville and Sims (1984) who presented the case for suppression to the International Commission on Zoological Nomenclature with further comments made by Hamilton (1985), Boulard (1985), and Lauterer (1985). A lack of action resulted in additional comments being published in 2014 again supporting the retention (Sanborn 2014; Marshall and Hill 2014) or the suppression (Boulard and Puissant 2014) of Tibicen.

AB - To date, 22 species of amphisbaenids have been recorded at Brazilian Amazon (Ribeiro et al. 2008), six of them are small and have two pre-cloacal pores (Hoogmoed & Avila-Pires 1991; Teixeira Jr. et al. 2014). Most of these species have narrow distributions, and its biology and phylogenetic relationships are poorly understood (Hoogmoed & Avila-Pires 1991). Amphisbaena mitchelli Procter, 1923 and A. miringoera Vanzolini, 1971 share several morphological similarities that could reflect phylogenetic relatedness (Vanzolini 1971). Both have two pre cloacal pores and a similar pattern of head scutelation, but whereas the first has 193-220 and 26-29 body and tail annuli, respectively, the latter has 250-264 and 22-24 (Vanzolini 1971).

AB - A second species, and first Central American record, of the phorid fly genus Lenkoa Borgmeier (Diptera: Phoridae). Many species of phorid flies have wingless or brachypterous females. Mostly, they belong to a group classified within the subfamily Metopininae corresponding to the Metopina group of genera of Brown (1992a) or the tribe Metopinini of Disney (2003, not 1987). The males of this group are much more typical in appearance, with well-developed wings, larger eyes, and fully developed abdominal tergites. These males carry females during a mating flight, often dispersing them to new breeding sites (Miller 1984). Generally, the sexual dimorphism is so great that the sexes cannot be confidently associated unless they are collected in copula. This has led to a profusion of species being described as males and females in separate genera. Some of these brachypterous females, both within the Metopinini and elsewhere in other Phoridae, have been correctly associated with their males when they are found together (e.g., Brown 1986, 1992b, 1994), but many remain unassociated.

AB - The eminent entomologist Aristide Caradja (1861-1955) published between 1925 and 1939, on his own or jointly with Edward Meyrick, a series of taxonomic papers on Chinese microlepidoptera including the descriptions of 18 new species in Yponomeutidae (Hyponomeutidae of authors). Their type specimens are currently deposited in two institutions, the Natural History Museum in London (BMNH: formerly British Museum of Natural History), as previously incorporated in the Meyrick collection, and the "Grigore Antipa" National Museum of Natural History in Bucharest, Romania (MGAB), as incorporated in the Caradja collection. The BMNH specimens were examined and illustrated by Clarke (1965). The type specimens of Oridryas kept in MGAB have never been studied since the original descriptions. PMID- 27701333 TI - A new river loach from the main channel of the upper Mekong in Yunnan (Cypriniformes: Nemacheilidae). AB - Nemacheilid loaches are a common element of fish assemblages of Southeast Asian streams. In particular, streams in tropical and subtropical regions with a gravelly to rocky substrate and a swift current are typically inhabited by several species of nemacheilid loaches. Up to six different species are reported to occur syntopically (Kottelat 1990). The vast majority of these loaches are allocated within the diverse genus Schistura, which accommodates about 200 valid species (Kottelat 2012). River loaches of the genus Schistura are defined as having the mouth moderately arched; the lower lip medially notched, not forming lateral labial pads; air bladder without a secondary chamber, and a maximum size between 25 mm and 120 mm SL (Kottelat 1990). PMID- 27701334 TI - Revising Australian Pristomerus (Hymenoptera, Ichneumonidae, Cremastinae): species with a tooth on the hind femur. AB - The Australian insect fauna is among the least-well studied in the world, and conservative estimates state that 75% of the species still await description. In the more species-rich groups, this percentage might be even larger, which is certainly the case in parasitoid wasps which have received very little attention by taxonomists. The genus Pristomerus of the family Ichneumonidae is distributed worldwide, with most species found in the tropics. Its members attack concealed larvae of small Lepidoptera, and several species are used in biocontrol. Five species have been reported from Australia, all of them endemic, but many more undescribed species are present in various collections. I here revise Australian Pristomerus, focussing on the species that bear a tooth on the ventral side of the hind femur. Twenty-two species are recorded, 19 of which are described as new: Pristomerus australiensis n. sp., P. bertschmanni n. sp., P. callitrinus n. sp., P. dundeei n. sp., P. flavicephalus n. sp., P. fourecksensis n. sp., P. gracilis n. sp., P. kakaduensis n. sp., P. laetus n. sp., P. luculentus n. sp., P. lunatus n. sp., P. mangiferus n. sp., P. merus n. sp., P. nedkellyi n. sp., P. pellicius n. sp., P. periculosus n. sp., P. stellatus n. sp., P. tenebrosus n. sp., and P. venustus n. sp. A dichotomous key and an online interactive key to the known Australian species with a tooth on the hind femur are provided, including photographs of all the species. The origin of the considerable number of Australian Pristomerus species remains unclear. They might represent Southern relict elements with affinities to South American taxa, or their ancestors might have immigrated from the Paleotropics in more recent times; this question can only be solved with a dated phylogeny of the genus. However, support for a Palaeotropic origin of at least a good portion of the taxa comes from their current distribution, as the Australian Pristomerus are found to be most diverse in the tropical habitats of Northern Queensland and the Northern Territories. PMID- 27701335 TI - Many things come in small packages: Revision of the clawless geckos (Crenadactylus: Diplodactylidae) of Australia. AB - We provide a taxonomic revision of the genus Crenadactylus, a group of very small clawless geckos from western and central Australia, with currently only one recognized species and four subspecies. Morphological comparisons were made on genotyped specimens from two recent genetic studies, then with an expanded sample to encompass all specimens to determine diagnostic characters in addition to morphological and geographic boundaries. Based on our findings, we elevate the subspecies Crenadactylus ocellatus ocellatus from south-western Australia and C. o. horni from the Central Uplands to full species. Consultation of the types of Diplodactylus (= Crenadactylus) bilineatus indicate they are C. ocellatus based on a dorsal pattern with intermixing of dark and pale scales not shared with any other taxa; we therefore maintain synonymy of 'D.' bilineatus with 'D.' ocellatus. We describe three new Western Australian species formerly allocated to C. o. horni: C. occidentalis sp. nov. from the western coast, C. tuberculatus sp. nov. from the Cape Range and C. pilbarensis sp. nov. from the Pilbara region. To stabilize the Kimberley taxa, we also raise C. ocellatus rostralis and C. ocellatus naso, both monophyletic taxa from the monsoonal tropics, to full species, while acknowledging further work is required on the C. naso species complex. All new species treated here possess distinctive morphological characters to diagnose them, including enlarged dorsal tubercles in C. tuberculatus sp. nov., a single enlarged supranasal in C. horni and a single enlarged postmental in C. pilbarensis sp. nov. Pattern was relatively conserved among taxa, with highly contrasting dark and pale longitudinal lines, with the exception of the type species C. ocellatus that possesses intermixed dark and pale scales and ocelli. Crenadactylus species are separated by deep genetic divergences and are usually allopatrically distributed. This indicates that despite being Australia's smallest geckos, or possibly because of it, these diminutive lizards have a long history of localised persistence through major climatic changes over millions of years.

L. caeruleus Schimmel, 1998 is recorded for the first time in Afghanistan, presence of L. funebris (Solsky, 1881) in Afghanistan is confirmed. In addition, some taxonomic and morphological notes on the Lacon species of Afghanistan and adjacent countries are given. PMID- 27701337 TI - On the vesica of Eucosmini and Grapholitini (Insecta: Lepidoptera: Tortricidae). AB - Eucosmini and Grapholitini are highly specialised and closely related tribes of the subfamily Olethreutinae of the family Tortricidae. Previous studies have shown that there is considerable similarity in the general shape of the everted vesica and structure of cornuti in these two tribes. In this study the possible function of the vesica during copulation is discussed based on everted vesicae of intact specimens treated with dichlorvos, a compound that causes eversion of the vesica and formation of the spermatophore. A comparison between chemically and mechanically everted vesicae showed that the vesica consists of two functionally different parts: an eversible and a non-eversible. Clear distinction in the position and function of deciduous and non-deciduous cornuti was observed; non deciduous cornuti are attached to the eversible part of the vesical and the deciduous cornuti to the non-eversible part. The mechanism of detachment of deciduous cornuti was revealed. Some peculiarities of the possible interaction between male and female genitalia are discussed.

PMID- 27701339 TI - Redescription of two troglobiotic species of Deuteraphorura Absolon, 1901
(Collembola, Onychiuridae) from the Western Carpathians. AB - Two species of the genus Deuteraphorura Absolon, 1901 from the Western Carpathian caves (Central Europe) are redescribed, namely D. kratochvili (Nosek, 1963) and D. schoenviszkyi (Loksa, 1967). Both species are characterized by the absence of pseudocelli on thoracic tergum I, presence of male ventral organ on abdominal terga II-III and 3 pseudocelli on hind margin of head. D. kratochvili is redescribed based on specimens from the type locality (Demanovska Cave System) and its intraspecific variability in morphological traits is discussed. Redescription of D. schoenviszkyi (Loksa, 1967) is based on specimens from the Slovak and Aggtelek Karst, the karst area where the type locality is situated. Both species are restricted to subterranean environment, thus classified as obligate cave forms (troglobionts). An identification key to Deuteraphorura species, characterized by absence of pseudocelli on thoracic segment I, is provided.

AB - Lake Malawi is known for its endemic haplochromine species flock, most notably the rock-dwelling cichlids known as mbuna. The group of mbuna referred to as the Pseudotropheus elongatus species group is currently comprised of Metriaclima spp., Tropheops spp., Cynotilapia spp., and Pseudotropheus spp. In this study, Chindongo, a new genus with the type species C. bellicosus, is described for additional species in this group. Chindongo is distinguished from other mbuna genera by 1) the presence of bicuspid teeth in the anterior portion of the outer row of both upper and lower jaw; 2) a moderately to steeply sloped vomer with a narrow rostral tip which makes an angle of between 53 degrees and 68 degrees with the parasphenoid; 3) a small mouth with the lower jaw slightly shorter than the upper; 4) a broad anterior dentigerous area on both premaxilla and dentary with three or more rows of teeth (usually 5-6 rows); 5) a flank melanin pattern consisting of vertical bars without horizontal elements at any stage of development. Chindongo bellicosus is distinguished by its color pattern and shallower body from the other species which we have transferred to Chindongo. We also describe six new elongate mbuna species and place them into three available genera, they include: Metriaclima flavicauda, M. usisyae, Tropheops kumwera, T. biriwera, T. kamtambo, and Cynotilapia chilundu.

PMID- 27701345 TI - Menieroclerus gen. nov.: A new genus for Thanasimodes nigropiceus (Kuwert, 1893) (Coleoptera: Cleridae: Clerinae). AB - Opilo nigropiceus Kuwert was described from a specimen collected in Bagamoyo on the north coast of Tanzania, though the description was devoid of informative morphological detail (Kuwert 1893). Without comment, Schenkling (1915) transferred O. nigropiceus to Thanasimodes Murray, a genus erected by Murray (1867) for a single specimen from 'Old Calabar' (south Nigeria) described as Thanasimodes metallicus Murray. Thanasimodes presently contains ten species and is distributed widely throughout Africa, from South Africa to the northernmost countries (Corporaal 1950; Gerstmeier 1998). PMID- 27701346 TI - Worldwide revision of the genus Fraseroscyphus Boero and Bouillon, 1993 (Cnidaria: Hydrozoa): an integrative approach to establish new generic diagnoses. AB - The morphological character of the hydrocladium and gonotheca origin from within the hydrothecal cavity has rarely been applied for generic diagnoses in hydrozoans. Its taxonomic value has been controversial for more than a century. The genus Fraseroscyphus Boero and Bouillon, 1993 (Hydrozoa: Sertulariidae) is a relatively recently debated case and it has been distinguished from Symplectoscyphus Marktanner-Turneretscher, 1890 based on this character. A review of this character in all published nominal species of the family Sertulariidae reveals that its occurrence is inconsistent at the genus level. However, phylogenetic analyses based on mitochondrial (16S) and nuclear (18S, 28S) genes support the position of Fraseroscyphus as a genus within the family Symplectoscyphidae Maronna et al., 2016. Comparisons of 16 morphological characters of 10 related species support the distinction of Fraseroscyphus from Antarctoscyphus and Symplectoscyphus by other characters in addition to the hydrocladial and gonothecal origin character. These new characters include the rarely-branched hydrocaulus, the absence of an apophysis, and the absence of an axillary hydrotheca. Furthermore, a revision based on the morphological character complex mentioned above using type and topotypic material, demonstrated that Sertularella sinuosa Fraser, 1948 (type species of Fraseroscyphus) and Symplectoscyphus huanghaiensis Tang & Huang, 1986 are junior synonyms of F. hozawai (Stechow, 1931) comb. nov. The assignment of Sertularella irregularis Trebilcock, 1928 and Sertularella macrogona Trebilcock, 1928 to Fraseroscyphus is also supported. In addition, sequence polymorphism of mitochondrial genes even within a single hydroid fragment was detected by the molecular cloning method, and is probably in part attributable to errors introduced by PCR, mitochondrial heteroplasmy and/or nuclear mitochondrial DNA (NUMTs). The adoption of the cloning method may be crucial to improve the sequence accuracy for some colonial hydrozoans. PMID- 27701347 TI - Phylogeny and genetic variation within the widely distributed Bluntnose Minnow, Pimephales notatus (Cyprinidae), in North America. AB - This study represents a phylogenetic analysis of Pimephales notatus, a widely distributed North American cyprinid fish species, using one mitochondrial (cytb) and two nuclear (S7 and Rag1) genes. Despite the broad geographic distribution of this species that includes independent basins, results suggest a largely drainage independent genetic structure. Results reveal a well-supported lineage in the Ozark Highlands, which is highly divergent from the remaining populations and may represent a long-term isolated lineage that should be considered as a separate conservation and management unit. All other remaining populations comprised a widely distributed lineage, covering most of the distribution for the species (from the Red River and tributaries of the Great Lakes in the north to the lower Mississippi and Mobile basin in the south, and from the Missouri River in the west to the Chesapeake and Albemarle Sound basins in the east). Phylogenetic, genetic diversity, and biogeographical data suggest that this wide-ranging lineage could have experienced a recent expansion to northern areas where populations exhibit little genetic variation. Results from molecular analyses reveal a distinctive lineage in the Ozarks and suggest that there is need for morphological analyses within P. notatus to determine its taxonomic status.

AB - A new species of Cnemaspis, Cnemaspis rajakarunai sp. nov. is described and is the fourth rock dwelling species belonging to the genus known from Sri Lanka. The new species is readily distinguished from all other congeners by the following combination of characters: adult snout-vent length 36-40 mm; precloacal pores absent, large femoero-precloacal scales 22; femoral pores 7-8, enlarged femoral scales 6; ventral scales 146-186; supralabials (to midorbital position) 7; supralabials (to angle of jaws) 9; total lamellae on finger IV 19-22, shape of the basal lamellae on toe IV elliptical; and its unique colour pattern. The new species is recorded from Salgala Forest an unprotected lowland rain forest.

In this paper we describe nine new species from Mexico, Guatemala, and El Salvador: P. trifiniensis Barrios-Izas & Anderson, new species (El Salvador and Guatemala); P. branstetteri Barrios-Izas & Anderson, new species (Guatemala and Mexico); P. longinoi Barrios-Izas & Anderson, new species (Guatemala and Mexico); P. cortezi Barrios-Izas & Anderson, new species (Guatemala and Mexico); P. canoi Barrios-Izas & Anderson, new species (Guatemala); P. schusteri Barrios-Izas & Anderson, new species (Guatemala and Mexico); P. daryi Barrios-Izas & Anderson, new species (Guatemala); P. yolnabajensis Barrios-Izas & Anderson, new species (Guatemala); and P. macalajauensis Barrios-Izas & Anderson, new species (Guatemala). The genus and the species are named and described, information on their geographical distributions is given and images of the habitus of both sexes and the aedeagus are presented. A key to the species of Plumolepilius based on males is included. The monophyly of Plumolepilius was confirmed by a parsimony analysis of external and male aedeagus morphology and the genus is best characterized by the presence of plumose scales lining the prosternal channel. Phylogenetic analysis supports that Lepilius Champion 1905 is the sister genus of Plumolepilius. PMID- 27701350 TI - The Oncometopia orbona species group (Hemiptera, Cicadellidae, Proconiini). AB - The Oncometopia orbona group of species is defined based on the characteristic structure of the male aedeagus. A key to males and females of 9 species is included, among which 5 are newly described from the U.S.A., Mexico, and Central America: O. orbona (F.), O. nigricans (Walker), O. obtusa (F.), O. clarior (Walker) (= Proconia badia Walker syn. n., Proconia scutellata Walker synonymy reinstated), O. hamiltoni sp. n., O. acicularis sp. n., O. lepida sp. n., O. pelvica sp. n., and O. unispina sp. n. The systematics of the group presents some unusual cases. In particular, O. lepida sp. n. and O. pelvica sp. n. differ from one another in the shape of the female genital chamber sclerites, but not in the male genitalia. Oncometopia nigricans is almost identical in the genitalic characters of both sexes to O. hamiltoni sp. n., from which it is dissimilar externally, as confirmed by morphometric analysis, but is externally similar to O. orbona, from which it strongly differs in both the male and female genitalia. The rare intermediate forms from northern Florida and southern Georgia are interpreted as orbona x nigricans hybrids. Oncometopia clarior is treated as a complex of species which at present cannot be separated.

PMID- 27701352 TI - Description of the first Oriental species of the ant genus Xymmer (Hymenoptera: Formicidae: Amblyoponinae). AB - The monotypic ant genus Xymmer Santschi, 1914 was established for X. muticus (Santschi, 1914) which has so far been known only from the West African subregion. The genus is easily distinguishable from the other amblyoponine genera by the anteromedian part of clypeus which is produced as a short rectangular lobe. Additional undescribed species had been found exclusively from Madagascar and Africa until recently. However, in March, 2015, a Xymmer colony was found in northern Central Vietnam. In the present paper Xymmer phungi sp. nov. is described as the first Oriental species of the genus. Although the worker of X. phungi is morphologically quite similar to that of X. muticus, the former is distinguishable from the latter by the following two characteristics of the worker: clypeal lobe 1/6 times as long as broad (vs. 1/3 times as long as broad in X. muticus); anterior margin of the lobe weakly concave (vs. almost straight in X. muticus). Xymmer phungi is well distinguished from Ethiopian Xymmer spp. for which 28S sequences are available from GenBank. Our observations suggest that the species feeds on geophilids (Chilopoda: Geophilomorpha). An updated key to Vietnamese genera of the subfamily Amblyoponinae is also provided.

No helminths were previously known from these two host species. The new genus is defined by the following characters: synlophe with 15 continuous ridges subequal in size, presence of left cuticular dilatation, a gap between ridges 1' and 2', bursa asymmetrical with dorsal ray hypertrophied and displaced to the right, and spicules not twisted. This is the first record of Viannaiidae from the Ctenomyidae, enlarging the host range of these parasites to five out of the 12 extant families of caviomorphs.

AB - A new legskate, Sinobatis andamanensis sp. nov. is described from a small collection of specimens taken off Phuket (Thailand) during an exploratory survey of the Andaman Sea. It is the first species of Sinobatis and the only legskate known from the northern Indian Ocean. Sinobatis andamanensis sp. nov. has an especially long and narrowly pointed snout (preorbital length exceeding 23% TL) with an interorbital distance 7-9.5 in snout length (up to 6.7 in other Sinobatis species). Molecular data are unavailable for most members of the genus, but based on morphology it shares with S. caerulea bluish dorsal and ventral surfaces when fresh and a long ventral head (length 36-42% TL). As well as differing in several morphometric differences, Sinobatis andamanensis sp. nov. seems to be a much smaller legskate (males adult from 186 mm DW vs. still immature at 540 mm DW in S. caerulea). Sinobatis bulbicauda also has an expanded posterior tail, but S. andamanensis sp. nov. differs from that species in having a narrower disc (width at anterior orbit 3.7-4.9 vs. 5.2-7.8 times mouth width) and anterior pelvic-fin lobes (base width 2.7-5.0 vs. 1.7-3.2 in distance between pelvic-fin origins), and shorter and less-conical tooth cusps and fewer vertebrae (total centra 126 133 vs. 148-171).

AB - A new species of Lilophaea Bechyne (Luperina) from Southern Brazil, Lilophaea sulina sp. nov. is described and illustrated. The complexity behind the taxonomic history for Lilophaea in relation to two similar genera (Luperodes and Monolepta), is approached herein. After the description of L. sulina sp. nov., 19 species of this genus are currently known, all Neotropical. An updated list of species of Lilophaea with their respective geographical distribution is provided. PMID- 27701358 TI - Description of two extraordinary new species of freshwater stingrays of the genus Potamotrygon endemic to the rio Tapajos basin, Brazil (Chondrichthyes: Potamotrygonidae), with notes on other Tapajos stingrays. AB - Stingrays from the rio Tapajos basin are reviewed based on material collected from its lower (i.e. from the mouth-lake to Itaituba), middle (from about the Sao Luiz rapids to the confluence of rios Juruena and Teles Pires), and upper (above the Juruena-Teles Pires confluence) segments. Two new species endemic to the mid and upper Tapajos, discovered long ago and common in the ornamental fish trade, are described. Potamotrygon albimaculata sp. nov. is part of the black stingray species group, and is diagnosed by its blackish brown dorsal disc color with numerous and generally evenly-spaced small whitish spots and faint ocelli, multiple rows of thorns broadly spread on dorsal and lateral tail, pelvic fins with broadly rounded apices, and two angular cartilages with the posterior far more slender but about as wide as the anterior angular. Potamotrygon jabuti sp. nov. is diagnosed by its marbled color pattern that undergoes remarkable change with growth as adults have elaborate designs of beige, golden to yellowish-orange spots or ocelli surrounded by a slender beige to golden mesh-like pattern, but neonates have simple, well-separated ocelli; this species also has a single to double row of tail thorns varying in their development, monognathic heterodonty with teeth of intermediate lateral rows of upper jaws larger and hexagonal, and two robust, more or less equally developed angular cartilages. Both species co occur in the relatively fast-flowing mid and upper Tapajos basin, but mostly occupy different areas of the river, with P. albimaculata sp. nov. more abundant in its central troughs but foraging at its margins, whereas P. jabuti sp. nov. is also present in smaller streams over rocky, sandy and leafy substrates. The Tapajos basin includes at least seven stingray species, but additional species probably also occur. Potamotrygon motoro, P. orbignyi, P. humerosa, Potamotrygon sp., and Paratrygon aiereba are present in the lower Tapajos mouth-lake, which may also include Plesiotrygon and Heliotrygon species. In addition to the new species described herein, P. orbignyi and Paratrygon cf. aiereba occur in the mid and upper Tapajos, along with another form (Potamotrygon cf. scobina) known only from the region of the Sao Luiz rapids. Therefore, three additional new species may be present in the Tapajos basin, which has one of the most diverse stingray assemblages known together with the rios Negro and Tocantins-Araguaia.

AB - A new name, Kirkegaardia, is proposed to replace Monticellina Laubier, 1961, a bitentaculate cirratulid polychaete genus, that is a junior homonym of the turbellarian Monticellina Westblad, 1953 (Platyhelminthes, Rhabdocoela). In addition, the opportunity is taken to complete a major revision of the genus including the redescription, revalidation, and separation of three species previously referred to synonymy with K. dorsobranchialis (Kirkegaard, 1959) and five other previously described species. In addition, 16 new species are described from the western North Atlantic, eastern and central Pacific, off western South America, and seas around Antarctica, bringing the total number of species in the genus to 38. Included are two new species of the unusual mud ball worms, first reported as Tharyx luticastellus Jumars, 1975, from southern California deep basins. A review of all 38 species reveals that three distinct species groups may be identified within the genus in addition to 5-6 species that may eventually be referred elsewhere. This review includes a discussion of the taxonomic characters and various newly defined character states that are found among species of Kirkegaardia. Several of these are unique among the Cirratulidae.

AB - BACKGROUND Despite the high frequency of hypotension during spinal anesthesia with proper sedation, no previous report has compared the hemodynamic effects of dexmedetomidine and midazolam sedation during spinal anesthesia. We compared the effects of bispectral index (BIS)-guided intravenous sedation using midazolam or dexmedetomidine on hemodynamics and recovery profiles in patients who underwent spinal anesthesia. MATERIAL AND METHODS One hundred and sixteen adult patients were randomly assigned to receive either midazolam (midazolam group; n=58) or dexmedetomidine (dexmedetomidine group; n=58) during spinal anesthesia. Systolic, diastolic, and mean arterial pressures; heart rates; peripheral oxygen saturations; and bispectral index scores were recorded during surgery, and Ramsay sedation scores and postanesthesia care unit (PACU) stay were monitored. RESULTS Hypotension occurred more frequently in the midazolam group (P<0.001) and bradycardia occurred more frequently in the dexmedetomidine group (P<0.001). Mean Ramsay sedation score was significantly lower in the dexmedetomidine group after arrival in the PACU (P=0.025) and PACU stay was significantly longer in the dexmedetomidine group (P=0.003). CONCLUSIONS BIS-guided dexmedetomidine sedation can attenuate intraoperative hypotension, but induces more bradycardia, prolongs PACU stay, and delays recovery from sedation in patients during and after spinal anesthesia as compared with midazolam sedation. PMID- 27701368 TI - Transcranial direct current stimulation for improving idiopathic Parkinson's syndrome. An abridged version of a Cochrane review. AB - INTRODUCTION: Idiopathic Parkinson's Disease (IPD) is a neurodegenerative disorder. The severity of disability usually increases with disease duration and affects patients' impairment, disability and health-related quality of life. A possible adjunct to improve outcomes in patients with IPD might be transcranial direct current stimulation (tDCS) to modulate cortical excitability and hence improving outcomes in people with IPD. EVIDENCE ACQUISITION: Until February 2016 we searched the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library; 2016, Issue 2), MEDLINE, EMBASE, CINAHL, AMED, Science Citation Index, the Physiotherapy Evidence Database (PEDro), Rehabdata, and Inspec and handsearched conference proceedings, and contacted authors and equipment manufacturers. We included only randomized controlled trials (RCTs) and randomized controlled crossover trials comparing tDCS versus control interventions in adults with IPD. EVIDENCE SYNTHESIS: Two authors independently extracted data and assessed trial quality. We included six trials with 137 participants. There was no effect of tDCS compared to sham tDCS in our primary outcome measure, impairment, as measured by the proportional change of the Unified Parkinson's Disease Rating Scale (UPDRS) (mean difference (MD) 7.10%, 95% confidence interval (CI) -19.18 to 4.97; P=0.25). There was evidence of an effect on UPDRS part III motor subsection score at the end of the intervention period (MD -14.43%, 95% CI -24.68 to -4.18; P=0.006). There was no evidence of an effect regarding the reduction in off time and on time with dyskinesia (MD 0.10 hours, 95% CI -0.14 to 0.34; P=0.41; and MD 0.00 hours, 95% CI -0.12 to 0.12; P=1, respectively). There was no evidence of an effect for gait speed, health related quality of life and safety/acceptability, measured by dropouts and adverse events (including death). CONCLUSIONS: There is insufficient evidence to determine the effects of tDCS in reducing off time and on time with dyskinesia and for improving health-related quality of life, disability and impairment in patients with IPD. PMID- 27701367 TI - Current management of diabetic patients with kidney disease: a renal-cardio endocrine perspective. AB - Diabetic kidney disease (DKD) is one of the most frequent and dangerous complications of diabetes mellitus type 2, affecting about one-third of the patients. DKD results in increased hospitalizations and mortality rates, especially due to cardiovascular complications. This high burden of kidney disease is mainly due to the increasing complexity of in- outpatient care for patients with DM. There is a strikingly complex interaction of kidney dysfunction with many aspects of diabetes care, such as redefinition of targets of treatment, interactions of traditional and non-traditional risk factors, and pharmacological issues related to pharmacokinetic and side effects of drugs. Particularly when not carefully managed, DKD increases the demand for renal replacement therapies, such as dialysis and kidney transplants. The combined economic and social costs of this disease are high and of concern to the world's health systems. The main objective of this review is to provide insight into the recommendations for the evaluation and stratification of DKD and how the presence of kidney disease changes the optimal management of diabetic patients from an integrated renal cardio-endocrine perspective. PMID- 27701370 TI - Intra-arterial injection of iloprost reduces the risk of early recoil after balloon angioplasty of below-the-knee vessels in patients with critical limb ischemia. AB - BACKGROUND: Previous studies demonstrated that early recoil is frequently observed in patients undergoing balloon angioplasty. The aim of this study was to evaluate the impact of intra-arterial administration of iloprost (Endoprost(r), Italfarmaco S.p.A., Milan, Italy) on early elastic recoil after balloon angioplasty of below-the-knee (BTK) vessels in patients with critical limb ischemia (CLI). METHODS: Between January 2015 and December 2015 32 patients with CLI underwent balloon angioplasty of at least one BTK vessel followed by intra arterial administration of iloprost. Early elastic recoil was defined as residual lumen compromise >10%. Early elastic recoil was determined on the basis of minimal lumen diameter (MLD) measurements at baseline (MLDbaseline), immediately after BTK balloon angioplasty (MLDpostdilation), and 15 minutes thereafter (MLD15min). RESULTS: Patients were predominantly female (18/32, 56.2%) with a mean age of 79.6 years (range 68- 87). Most of the patients were diabetics (25/32, 78.1%). An occlusion was present in 24 cases (75%). Mean BTK lesion length was 144.1 mm (range 22-320). Mean MLD measurements were 0.1 mm (range 0 0.5; MLDbaseline), 2.5 mm (range 1.9-3; MLDpostdilation), and 1.9 mm (range 0.7 3; MLD15min). Early elastic recoil was recorded in 14 patients (43.8%). The mean percentage of elastic recoil after 15 minutes was 21.4%. CONCLUSIONS: In our experience intra-arterial administration of iloprost reduces the risk of early elastic recoil after balloon angioplasty of BTK vessels in patients with CLI. Further analyses with larger population studies and randomized trials are needed to validate this therapeutic option. PMID- 27701371 TI - Burnout syndrome and wellbeing in anesthesiologists: the importance of emotion regulation strategies. AB - Anesthesiologists face stressful working conditions that can culminate in burnout syndrome. Despite various studies and protective measures which have attempted to prevent this situation, burnout continues to be a problem within the profession, impacting negatively on physicians' lives and their performance. In this review article mechanisms and consequences of burnout are described in addition to individual strategies for stress management and burnout reduction with potential impact on health care quality and wellbeing in anesthesiologists. Organizational strategies appear to have an important role in burnout reduction but need to be used in conjunction with individual programs. The latter are essential to both reducing stress and burnout in anesthesiologists and improving happiness and wellbeing. New measures of emotion regulation strategies such as mindfulness, self-compassion, resilience and empathy promotion have been shown to be approaches with substantial supporting evidence for reducing burnout and improving stress management. The evaluation and implementation of these self regulatory competencies is a challenge. Further research is necessary to identify which programs will best suit the needs of anesthesiologists and to measure their effects on patient care and health care system quality. PMID- 27701372 TI - Can pre-procedure neuroaxial ultrasound improve the identification of the potential epidural space when compared with anatomical landmarks? A prospective randomized study. AB - BACKGROUND: Regional epidural analgesia is considered the gold standard for pain treatment in labor. However, epidural catheter placement may be a challenging procedure because of the difficulty in the palpation of anatomical landmarks, particularly in pregnant women. Pre-procedural neuroaxial ultrasound may facilitate the procedure. METHODS: A prospective randomized controlled study was conducted in a labor ward. Two groups of women undergoing epidural analgesia were randomized: Group A (N.=28), which was subjected to the loss of resistance technique, and Group B (N.=30) which was subjected to an ultrasound (US)-assisted procedure. The real depth of epidural space was calculated in both groups by measuring the needle skin-to-tip distance, while the US depth was measured only in Group B. RESULTS: The mean number of attempts in group A (3.43+/-3.8) was significantly higher than in Group B (1.70+/-0.87, P=0.019). Analysis of data from Group B revealed a strong positive correlation between the epidural real depth and US depth (r=0.88, P<0.0001). CONCLUSIONS: The US-assisted technique for epidural catheter placement for labor analgesia is safe, effective, easy to perform, and is a valuable aid to improve the identification of the epidural space compared with the palpation of anatomical landmarks and the loss of resistance technique. Pre-puncture ultrasound assessment shows the exact location of the intervertebral space, the optimal point of insertion and the tilt angle of the needle, the depth of the epidural space and any anatomical abnormalities of the spine, thereby increasing the success rate and reducing procedural complications of the blind approach. PMID- 27701369 TI - Transaxillary versus transaortic approach for transcatheter aortic valve implantation with CoreValve Revalving System: insights from multicenter experience. AB - BACKGROUND: About one-third of candidates for transcatheter aortic valve implantation (TAVI) suffer from severe peripheral artery disease, making the routine femoral approach difficult or impossible. The aim was to compare the transaxillary (TAx) and the transaortic (TAo) route for TAVI with Medtronic CoreValve Revalving System (CRS). METHODS: Out of 1049 consecutive TAVI with 18F CRS, 242 (23%) were treated in 4 high-volume Italian Centre through TAx (61%) and TAo (39%). RESULTS: The devices success was similar (P=0.16) with a trend to a lower incidence of significant paravalvular leak (6% vs. 14%, P=0.07) and a significant reduction of permanent pacemaker (PPM) implantation (13% vs. 34%, P=0.017) in the TAo. However, this route showed a higher incidence of acute kidney injury (P=0.016) and a longer hospital stay after the index procedure (days 10 [8-14] vs. 8 [7-12], P=0.001). By a multivariate analysis the vascular access is an independent predictor for a longer hospital stay (TAo route; OR=0.37, 95% CI: 0.18-0.75; P=0.006) and for PPM implantation (TAx route; OR=3.7, 95% CI: 1.2-10.8; P=0.017). CONCLUSIONS: Although the higher clinical risk profile of transaortic population, the TAo approach showed an equally high device success with similar 30-day safety and 1year efficacy, compared to TAx route. However, due to non-procedure-specific complications post-TAo TAVI, this route requires a specialized postoperative care and the treatment of patients in highly specialized and experienced centers.

PMID- 27701375 TI - Intraoperative radiotherapy in gastric and esophageal cancer: meta-analysis of long-term outcomes and complications. AB - INTRODUCTION: The treatment effects of intraoperative radiotherapy (IORT) for gastric and esophageal cancer remain uncertain. We therefore performed meta analyses to investigate whether IORT was associated with more favorable oncologic outcomes when compared to non-IORT for patients who have gastric or esophageal cancer. EVIDENCE ACQUISITION: PubMed, Embase, and the references of relevant studies were systematically searched up to March 2016. Outcomes were analyzed with fixed-effect or random-effect models, and the meta-analysis was completed with odds ratio (OR), hazards ratio (HR), and 95% confidence intervals (CI) as effect values. EVIDENCE SYNTHESIS: Eleven studies were included, nine for gastric cancer and two for esophageal cancer. The studies included 1581 patients, 570 in the IORT group and 1011 in the control group. There was no significant difference in overall survival (OS) between the IORT group and control group (HR=0.91, 95% CI: 0.73-1.13; P=0.38). Two subgroups based on cancer type also had the similar results (gastric group: HR=0.98, 95% CI: 0.78-1.24, P=0.87; esophagus group: HR=0.63, 95% CI: 0.37-1.05, P=0.08). Besides, IORT showed favorable effects for patients with cancer in stage II and stage III and had the advantage of loco regional control. Regarding the complications, the occurrence rate had no significant difference between the IORT group and control group (OR=1.15; 95% CI: 0.77-1.72; P=0.50). CONCLUSIONS: According to our meta-analysis, IORT did not extend the OS in gastric cancer and esophageal cancer patients, but had a favorable effect for specific stage patients to show loco-regional control, and did not increase the risk of complications. PMID- 27701376 TI - Predictors of rapid disease progression in autosomal dominant polycystic kidney disease. AB - Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common genetic diseases with a reported prevalence of 1:400 to 1:1000. Since the intact kidneys can compensate for the loss of glomerular filtration in ADPKD patients, renal insufficiency usually remains undetected until almost the fourth decade of life. Hereafter, reliable diagnostic and prognostic biomarkers to identify ADPKD progression are urgently needed. Several studies and systematic reviews tried to identify markers or predictors of rapid disease progression of ADPKD. The aim of this study is to review predictors of rapid disease progression of ADPKD that can be useful to the clinician. We will describe several factors associated with rapid progression of ADPKD derived from retrospective or cross-sectional studies, suggesting the best and most useful predictors that may help to patients management in clinical practice. We will attempt to identify the most useful predictors of rapid disease progression of ADPKD: established TKV growth rate >5% per year, annual estimated glomerular filtration rate decline >5 mL/min/1.73 m2, truncating PKD1 mutations and elevated plasma copeptin level. The combination of several factors that can predict the rapid ADPKD progression is more accurate than a single-marker strategy. The "PRO-PKD" risk scoring system combined with TKV, can be useful in order to evaluate the ADPKD patients and they appear to be appropriate predictors of progression disease. Moreover levels of copeptin and some urinary markers can be matched to these factors for improved patient assessment in rapid progression. PMID- 27701377 TI - Global cooling as a driver of diversification in a major marine clade. AB - Climate is a strong driver of global diversity and will become increasingly important as human influences drive temperature changes at unprecedented rates. Here we investigate diversification and speciation trends within a diverse group of aquatic crustaceans, the Anomura. We use a phylogenetic framework to demonstrate that speciation rate is correlated with global cooling across the entire tree, in contrast to previous studies. Additionally, we find that marine clades continue to show evidence of increased speciation rates with cooler global temperatures, while the single freshwater clade shows the opposite trend with speciation rates positively correlated to global warming. Our findings suggest that both global cooling and warming lead to diversification and that habitat plays a role in the responses of species to climate change. These results have important implications for our understanding of how extant biota respond to ongoing climate change and are of particular importance for conservation planning of marine ecosystems. PMID- 27701378 TI - Donor and host photoreceptors engage in material transfer following transplantation of post-mitotic photoreceptor precursors. AB - Photoreceptor replacement by transplantation is proposed as a treatment for blindness. Transplantation of healthy photoreceptor precursor cells into diseased murine eyes leads to the presence of functional photoreceptors within host retinae that express an array of donor-specific proteins. The resulting improvement in visual function was understood to be due to donor cells integrating within host retinae. Here, however, we show that while integration occurs the majority of donor-reporter-labelled cells in the host arises as a result of material transfer between donor and host photoreceptors. Material transfer does not involve permanent donor-host nuclear or cell-cell fusion, or the uptake of free protein or nucleic acid from the extracellular environment. Instead, RNA and/or protein are exchanged between donor and host cells in vivo. These data require a re-evaluation of the mechanisms underlying rescue by photoreceptor transplantation and raise the possibility of material transfer as a strategy for the treatment of retinal disorders. PMID- 27701379 TI - Hypoplastic left heart syndrome: from comfort care to long-term survival. AB - The management of hypoplastic left heart syndrome (HLHS) has changed substantially over the past four decades. In the 1970s, children with HLHS could only be provided with supportive care. As a result, most of these unfortunate children died within the neonatal period. The advent of the Norwood procedure in the early 1980s has changed the prognosis for these children, and the majority now undergoing a series of three surgical stages that can support survival beyond the neonatal period and into early adulthood. This review will focus on the Norwood procedure and the other important innovations of the last half century that have improved our outlook toward children born with HLHS. PMID- 27701381 TI - Retinal transplantation of photoreceptors results in donor-host cytoplasmic exchange. AB - Pre-clinical studies provided evidence for successful photoreceptor cell replacement therapy. Migration and integration of donor photoreceptors into the retina has been proposed as the underlying mechanism for restored visual function. Here we reveal that donor photoreceptors do not structurally integrate into the retinal tissue but instead reside between the photoreceptor layer and the retinal pigment epithelium, the so-called sub-retinal space, and exchange intracellular material with host photoreceptors. By combining single-cell analysis, Cre/lox technology and independent labelling of the cytoplasm and nucleus, we reliably track allogeneic transplants demonstrating cellular content transfer between graft and host photoreceptors without nuclear translocation. Our results contradict the common view that transplanted photoreceptors migrate and integrate into the photoreceptor layer of recipients and therefore imply a re interpretation of previous photoreceptor transplantation studies. Furthermore, the observed interaction of donor with host photoreceptors may represent an unexpected mechanism for the treatment of blinding diseases in future cell therapy approaches. PMID- 27701380 TI - Identification of Helicobacter pylori and the evolution of an efficacious childhood vaccine to protect against gastritis and peptic ulcer disease. AB - Establishment of Helicobacter pylori infection as an etiologic agent of peptic ulcer disease and other gastric pathologies marked a revolution in gastroenterology which spurred an enormous interest in gastric physiology and immunology research. The association was soon also demonstrated in children as well. Application of antimicrobial therapies have proven remarkably efficacious in eradicating H. pylori and curing pediatric patients of duodenal ulcers as well as gastritis, negating a lifetime of ineffective therapy and life-threatening disease. Countries with high H. pylori prevalence and where H. pylori associated gastric cancer remains a primary cause of death due to cancer however would benefit from childhood vaccination. Studies in rodents and humans utilizing oral vaccination with bacterial exotoxin adjuvants demonstrated potential for limiting H. pylori colonization in the stomach. Almost 25 y of vaccine research recently culminated in a phase III clinical trial of over 4,000 children aged 6-15 y old to test an oral vaccine consisting of the H. pylori urease B subunit genetically fused to the E. coli heat labile toxin. Vaccination was demonstrated to have an efficacy of over 70%. Vaccination may now serve as an effective strategy to significantly reduce H. pylori associated disease in children throughout the world. PMID- 27701383 TI - Risk of hospitalisation and death due to bone fractures after breast cancer: a registry-based cohort study. AB - BACKGROUND: Bone fractures may have an impact on prognosis of breast cancer. The long-term risks of bone fracture in breast cancer patients have not been thoroughly studied. METHODS: Poisson regression was used to investigate the incidence of hospitalisation due to bone fracture comparing women with and without breast cancer based on Swedish National registers. Cox regression was used to investigate the risk of being hospitalised with bone fracture, and subsequent risk of death, in a regional cohort of breast cancer patients. RESULTS: For breast cancer patients, the 5-year risk of bone fracture hospitalisation was 4.8% and the 30-day risk of death following a bone fracture hospitalisation was 2.0%. Compared with the general population, breast cancer patients had incidence rate ratios of 1.25 (95% CI: 1.23-1.28) and 1.18 (95% CI: 1.14-1.22) for hospitalisation due to any bone fracture and hip fracture, respectively. These ratios remained significantly increased for 10 years. Comorbidities (Charlson Comorbidity Index ?1) were associated with the risk of being hospitalised with bone fracture. Women taking aromatase inhibitors were at an increased risk as compared with women taking tamoxifen (HR=1.48; 95% CI: 0.98 2.22). Breast cancer patients hospitalised for a bone fracture showed a higher risk of death (HR=1.83; 95% CI: 1.50-2.22) compared with those without bone fracture. CONCLUSIONS: Women with a previous breast cancer diagnosis are at an increased risk of hospitalisation due to a bone fracture, particularly if they have other comorbidities. PMID- 27701382 TI - Fhf2 gene deletion causes temperature-sensitive cardiac conduction failure. AB - Fever is a highly conserved systemic response to infection dating back over 600 million years. Although conferring a survival benefit, fever can negatively impact the function of excitable tissues, such as the heart, producing cardiac arrhythmias. Here we show that mice lacking fibroblast growth factor homologous factor 2 (FHF2) have normal cardiac rhythm at baseline, but increasing core body temperature by as little as 3 degrees C causes coved-type ST elevations and progressive conduction failure that is fully reversible upon return to normothermia. FHF2-deficient cardiomyocytes generate action potentials upon current injection at 25 degrees C but are unexcitable at 40 degrees C. The absence of FHF2 accelerates the rate of closed-state and open-state sodium channel inactivation, which synergizes with temperature-dependent enhancement of inactivation rate to severely suppress cardiac sodium currents at elevated temperatures. Our experimental and computational results identify an essential role for FHF2 in dictating myocardial excitability and conduction that safeguards against temperature-sensitive conduction failure. PMID- 27701384 TI - Reproductive and hormonal factors in relation to survival and platinum resistance among ovarian cancer cases. AB - BACKGROUND: Ovarian cancer survival is poor, particularly for platinum-resistant cases. The previous literature on pre-diagnostic reproductive factors and ovarian cancer survival has been mixed. Therefore, we evaluated pre-diagnostic reproductive and hormonal factors with overall survival and, additionally, platinum-chemotherapy resistance. METHODS: We followed 1649 invasive epithelial ovarian cancer cases who were enrolled between 1992 and 2008 for overall mortality within the New England Case-Control Study and abstracted chemotherapy data on a subset (n=449). We assessed pre-diagnostic reproductive and hormonal factors during in-person interviews. We calculated hazard ratios (HRs) using Cox proportional hazards models. RESULTS: We observed 911 all-cause deaths among 1649 ovarian cancer cases. Self-reported endometriosis and longer duration of hormone therapy use were associated with improved survival (HR: 0.72; 95% confidence interval (CI): 0.54-0.94 and HR, ?5 years vs never: 0.70; 95% CI: 0.55-0.90, respectively). Older age at menopause and menarche were associated with worse survival (HR, ?50 vs >50 years: 1.23; 95% CI: 1.03-1.46 and HR, 13 vs <13 years: 1.24; 95% CI: 1.06-1.44, respectively). We observed no association between oral contraceptive use, parity and tubal ligation, and overall survival. No significant associations were observed for any of the reproductive and hormonal factors and platinum resistance. CONCLUSIONS: These results suggest that pre diagnostic exposures such as endometriosis and HT use may influence overall survival among ovarian cancer patients. PMID- 27701385 TI - A prognostic profile of hypoxia-induced genes for localised high-grade soft tissue sarcoma. AB - BACKGROUND: For decades, tumour hypoxia has been pursued as a cancer treatment target. However, prognostic and predictive biomarkers are essential for the use of this target in the clinic. This study investigates the prognostic value of a hypoxia-induced gene profile in localised soft tissue sarcoma (STS). METHODS: The hypoxia-induced gene quantification was performed by real-time quantitative PCR (RT-qPCR) of formalin-fixed, paraffin-embedded tissue samples. The gene expression cut-points were determined in a test cohort of 55 STS patients and used to allocate each patient into a more or a less hypoxic group. The cut-points found in the test cohort were applied to a cohort of 77 STS patients for validation. RESULTS: For patients with localised high-grade STS treated with surgery with or without postoperative radiation therapy, the prognostic value of the hypoxia-induced gene profile was proved in the test cohort and confirmed in the validation cohort. After adjustment for confounders, the hazard ratio (HR) was 3.2 (95% CI: 1.5; 7.0) for patients with more hypoxic tumours compared with patients with less hypoxic tumours regarding disease-specific survival. Moreover, for the development of metastatic disease, the HR was 2.61 (95% CI: 1.27; 5.33). CONCLUSIONS: The hypoxia-induced gene profile is a validated independent prognostic marker that may help identify STS patients needing more aggressive or different adjuvant treatment. PMID- 27701386 TI - Reproductive history and risk of colorectal adenocarcinoma in parous women: a Nordic population-based case-control study. AB - BACKGROUND: Data are conflicting regarding the role of endogenous sex hormones in colorectal carcinogenesis. In this large population-based study, we pooled data from birth and cancer registries in four Nordic countries, to evaluate the risk of colorectal adenocarcinoma in relation to women's reproductive history. METHODS: We conducted a population-based case-control study among women registered in Nordic birth registries. The study included colorectal adenocarcinoma cases diagnosed in Denmark, Finland, Norway, and Sweden during 1967-2013 and up to 10 matched controls per case, in total 22 185 cases and 220 246 controls. Odds ratios (ORs) with 95% confidence intervals (95% CIs) were derived from conditional logistic regression models. We had limited information available on possible confounders. RESULTS: We found no evidence for associations between colorectal adenocarcinoma and parity, age at first and last birth, and time since first and last birth. The risk estimates were also close to unity for specific cancer subsites (proximal and distal colon and rectum). As well, when the analyses were stratified on menopausal status, parity, and mother's year of birth, no indication of associations was found. CONCLUSIONS: In this large, Nordic population-based study, no evidence for associations was found between women's reproductive history and colorectal adenocarcinoma in parous women. PMID- 27701387 TI - Factors associated with recurrence and survival length following relapse in patients with neuroblastoma. AB - BACKGROUND: Despite therapeutic advances, survival following relapse for neuroblastoma patients remains poor. We investigated clinical and biological factors associated with length of progression-free and overall survival following relapse in UK neuroblastoma patients. METHODS: All cases of relapsed neuroblastoma, diagnosed during 1990-2010, were identified from four Paediatric Oncology principal treatment centres. Kaplan-Meier and Cox regression analyses were used to calculate post-relapse overall survival (PROS), post-relapse progression-free survival (PRPFS) between relapse and further progression, and to investigate influencing factors. RESULTS: One hundred eighty-nine cases were identified from case notes, 159 (84.0%) high risk and 17 (9.0%), unresectable, MYCN non-amplified (non-MNA) intermediate risk (IR). For high-risk patients diagnosed >2000, median PROS was 8.4 months (interquartile range (IQR)=3.0-17.4) and median PRPFS was 4.7 months (IQR=2.1-7.1). For IR, unresectable non-MNA patients, median PROS was 11.8 months (IQR 9.0-51.6) and 5-year PROS was 24% (95% CI 7-45%). MYCN amplified (MNA) disease and bone marrow metastases at diagnosis were independently associated with worse PROS for high-risk cases. Eighty percent of high-risk relapses occurred within 2 years of diagnosis compared with 50% of unresectable non-MNA IR disease. CONCLUSIONS: Patients with relapsed HR neuroblastomas should be treatment stratified according to MYCN status and PRPFS should be the primary endpoint in early phase clinical trials. The failure to salvage the majority of IR neuroblastoma is concerning, supporting investigation of intensification of upfront treatment regimens in this group to determine whether their use would diminish likelihood of relapse. PMID- 27701388 TI - Patterns of response to anti-PD-1 treatment: an exploratory comparison of four radiological response criteria and associations with overall survival in metastatic melanoma patients. AB - BACKGROUND: Radiological assessment of response to checkpoint inhibitors remains imperfect. We evaluated individual lesion and inter-patient response by response evaluation (RECIST) 1.1, immune-related response criteria (irRC), CHOI and modified CHOI (mCHOI) and correlated response with overall survival (OS). METHODS: Thirty-seven patients with 567 measurable lesions treated with pembrolizumab in the Keynote 001 trial were studied. Association of response with OS was determined. RESULTS: Response varied according to site; lung lesions had the highest rate of complete response (69 out of 163 (42%) vs other sites 71 out of 404 (18%), P<0.0001). Delayed response post first scan was seen in 2 out of 37 (5%) deemed progressive (PD) by RECIST and 2 out of 14 (14%) deemed PD by irRC. Modified CHOI criteria showed response of 38% (14 out of 37). Change in tumour size and density on first follow-up assessment was associated with OS with each 1000 mm2 increase in tumour size from baseline increasing the hazard of dying by 25.9% (HR=1.259, (95% CI=1.116-1.420), P=0.0002). Similarly, each 20HU increase in density increased the HR by 15% (HR=1.15, (95% CI 1.045-1.260), P=0.004). Response defined by any criteria had superior OS (CHOI P=0.0084; mCHOI P=0.0183; irRC P<0.0001 and RECIST P=0.0003). CONCLUSIONS: Response by any criterion was prognostic. Novel patterns of response and changes on treatment in tumour density suggest complex anti-tumour responses to immunotherapy. PMID- 27701391 TI - Epigenetics: Imprinting evolution in Arabidopsis.

PMID- 27701389 TI - Intermediate-stage hepatocellular carcinoma treated with hepatic resection: the NSP score as an aid to decision-making. AB - BACKGROUND: The subgroups of patients with intermediate-stage (BCLC-B) hepatocellular carcinoma (HCC) who would truly benefit from hepatic resection (HR) are unknown. An objective point score was established to guide the selection of these patients for HR. METHODS: In all, 255 consecutive patients with intermediate-stage HCC treated with HR were evaluated retrospectively and included in this study (the training cohort). The variables on overall survival (OS, log-rank test) were investigated and a point score (the NSP score) was developed by using a Cox-regression model and validated in an independent external cohort from another institution (n=169). RESULTS: The NSP score differentiated two groups of patients (?1, >1 point) with distinct prognoses (median OS, 61.3 vs 19.3 months; P<0.001). A high NSP score was associated with increased major adverse events after HR (5.6 vs 13.8%, P=0.027). Its predictive accuracy as determined by the area under the receiver operating characteristic curve (AUC) at 1, 3, and 5 years (AUCs 0.688, 0.739, and 0.732) was greater than the other six staging systems for HCC (0.513-0.677). The findings were supported by the validation cohort. CONCLUSIONS: The NSP scoring system is more accurate in selecting patients with intermediate-stage HCC for HR.

AB - Melanocortin-4-receptor (MC4R)-expressing neurons modulate food intake and preference in rodents but their role in human food preference is unknown. Here we show that compared with lean and weight-matched controls, MC4R deficient individuals exhibited a markedly increased preference for high fat, but a significantly reduced preference for high sucrose food. These effects mirror those in Mc4r null rodents and provide evidence for a central molecular circuit influencing human macronutrient preference. PMID- 27701399 TI - An Exon-Specific U1snRNA Induces a Robust Factor IX Activity in Mice Expressing Multiple Human FIX Splicing Mutants. AB - In cellular models we have demonstrated that a unique U1snRNA targeting an intronic region downstream of a defective exon (Exon-specific U1snRNA, ExSpeU1) can rescue multiple exon-skipping mutations, a relevant cause of genetic disease. Here, we explored in mice the ExSpeU1 U1fix9 toward two model Hemophilia B causing mutations at the 5' (c.519A > G) or 3' (c.392-8T > G) splice sites of F9 exon 5. Hydrodynamic injection of wt-BALB/C mice with plasmids expressing the wt and mutant (hFIX-2G5'ss and hFIX-8G3'ss) splicing-competent human factor IX (hFIX) cassettes resulted in the expression of hFIX transcripts lacking exon 5 in liver, and in low plasma levels of inactive hFIX. Coinjection of U1fix9, but not of U1wt, restored exon inclusion of variants and in the intrinsically weak FIXwt context. This resulted in appreciable circulating hFIX levels (mean +/- SD; hFIX 2G5'ss, 1.0 +/- 0.5 ug/ml; hFIX-8G3'ss, 1.2 +/- 0.3 ug/ml; and hFIXwt, 1.9 +/- 0.6 ug/ml), leading to a striking shortening (from ~100 seconds of untreated mice to ~80 seconds) of FIX-dependent coagulation times, indicating a hFIX with normal specific activity. This is the first proof-of-concept in vivo that a unique ExSpeU1 can efficiently rescue gene expression impaired by distinct exon-skipping variants, which extends the applicability of ExSpeU1s to panels of mutations and thus cohort of patients. PMID- 27701400 TI - Tissue-specific Calibration of Real-time PCR Facilitates Absolute Quantification of Plasmid DNA in Biodistribution Studies. AB - Analysis of the tissue distribution of plasmid DNA after administration of nonviral gene delivery systems is best accomplished using quantitative real-time polymerase chain reaction (qPCR), although published strategies do not allow determination of the absolute mass of plasmid delivered to different tissues. Generally, data is expressed as the mass of plasmid relative to the mass of genomic DNA (gDNA) in the sample. This strategy is adequate for comparisons of efficiency of delivery to a single site but it does not allow direct comparison of delivery to multiple tissues, as the mass of gDNA extracted per unit mass of each tissue is different. We show here that by constructing qPCR standard curves for each tissue it is possible to determine the dose of intact plasmid remaining in each tissue, which is a more useful parameter when comparing the fates of different formulations of DNA. We exemplify the use of this tissue-specific qPCR method by comparing the delivery of naked DNA, cationic DNA complexes, and neutral PEGylated DNA complexes after intramuscular injection. Generally, larger masses of intact plasmid were present 24 hours after injection of DNA complexes, and neutral complexes resulted in delivery of a larger mass of intact plasmid to the spleen. PMID- 27701401 TI - The Functionality of Minimal PiggyBac Transposons in Mammalian Cells. AB - Minimal piggyBac vectors are a modified single-plasmid version of the classical piggyBac delivery system that can be used for stable transgene integration. These vectors have a truncated terminal domain in the delivery cassette and thus, integrate significantly less flanking transposon DNA into host cell chromatin than classical piggyBac vectors. Herein, we test various characteristics of this modified transposon. The integration efficiency of minimal piggyBac vectors was inversely related to the size of both the transposon and the entire plasmid, but inserts as large as 15 kb were efficiently integrated. Open and super-coiled vectors demonstrated the same integration efficiency while DNA methylation decreased the integration efficiency and silenced the expression of previously integrated sequences in some cell types. Importantly, the incidence of plasmid backbone integration was not increased above that seen in nontransposon control vectors. In BALB/c mice, we demonstrated prolonged expression of two transgenes (intracellular mCherry and secretable Gaussia luciferase) when delivered by the minimal piggyBac that resulted in a more sustained antibody production against the immunogenic luciferase than when delivered by a transient (nontransposon) vector plasmid. We conclude that minimal piggyBac vectors are an effective alternative to other integrative systems for stable DNA delivery in vitro and in vivo.

PMID- 27701403 TI - Genome-scale high-resolution mapping of activating and repressive nucleotides in regulatory regions. AB - Massively parallel reporter assays (MPRAs) enable nucleotide-resolution dissection of transcriptional regulatory regions, such as enhancers, but only few regions at a time. Here we present a combined experimental and computational approach, Systematic high-resolution activation and repression profiling with reporter tiling using MPRA (Sharpr-MPRA), that allows high-resolution analysis of thousands of regions simultaneously. Sharpr-MPRA combines dense tiling of overlapping MPRA constructs with a probabilistic graphical model to recognize functional regulatory nucleotides, and to distinguish activating and repressive nucleotides, using their inferred contribution to reporter gene expression. We used Sharpr-MPRA to test 4.6 million nucleotides spanning 15,000 putative regulatory regions tiled at 5-nucleotide resolution in two human cell types. Our results recovered known cell-type-specific regulatory motifs and evolutionarily conserved nucleotides, and distinguished known activating and repressive motifs. Our results also showed that endogenous chromatin state and DNA accessibility are both predictive of regulatory function in reporter assays, identified retroviral elements with activating roles, and uncovered 'attenuator' motifs with repressive roles in active chromatin. PMID- 27701404 TI - A multicenter study benchmarks software tools for label-free proteome quantification. AB - Consistent and accurate quantification of proteins by mass spectrometry (MS) based proteomics depends on the performance of instruments, acquisition methods and data analysis software. In collaboration with the software developers, we evaluated OpenSWATH, SWATH 2.0, Skyline, Spectronaut and DIA-Umpire, five of the most widely used software methods for processing data from sequential window acquisition of all theoretical fragment-ion spectra (SWATH)-MS, which uses data independent acquisition (DIA) for label-free protein quantification. We analyzed high-complexity test data sets from hybrid proteome samples of defined quantitative composition acquired on two different MS instruments using different SWATH isolation-window setups. For consistent evaluation, we developed LFQbench, an R package, to calculate metrics of precision and accuracy in label-free quantitative MS and report the identification performance, robustness and specificity of each software tool. Our reference data sets enabled developers to improve their software tools. After optimization, all tools provided highly convergent identification and reliable quantification performance, underscoring their robustness for label-free quantitative proteomics. PMID- 27701405 TI - Membrane lipidomics in schizophrenia patients: a correlational study with clinical and cognitive manifestations. AB - Schizophrenia is a severe mental condition in which several lipid abnormalities either structural or metabolic-have been described. We tested the hypothesis that an abnormality in membrane lipid composition may contribute to aberrant dopamine signaling, and thereby symptoms and cognitive impairment, in schizophrenia (SCZ) patients. Antipsychotic-medicated and clinically stable SCZ outpatients (n=74) were compared with matched healthy subjects (HC, n=40). A lipidomic analysis was performed in red blood cell (RBC) membranes examining the major phospholipid (PL) classes and their associated fatty acids (FAs). Clinical manifestations were examined using the positive and negative syndrome scale (PANSS). Cognitive function was assessed using the Continuous Performance Test, Salience Attribution Test and Wisconsin Card Sorting Test. Sphingomyelin (SM) percentage was the lipid abnormality most robustly associated with a schizophrenia diagnosis. Two groups of patients were defined. The first group (SCZ c/SM-) is characterized by a low SM membrane content. In this group, all other PL classes, plasmalogen and key polyunsaturated FAs known to be involved in brain function, were significantly modified, identifying a very specific membrane lipid cluster. The second patient group (SCZ c/SM+) was similar to HCs in terms of RBC membrane SM composition. Compared with SCZ c/SM+, SCZ c/SM- patients were characterized by significantly more severe PANSS total, positive, disorganized/cognitive and excited psychopathology. Cognitive performance was also significantly poorer in this subgroup. These data show that a specific RBC membrane lipid cluster is associated with clinical and cognitive manifestations of dopamine dysfunction in schizophrenia patients. We speculate that this membrane lipid abnormality influences presynaptic dopamine signaling. PMID- 27701406 TI - Impaired GABA synthesis, uptake and release are associated with depression-like behaviors induced by chronic mild stress. AB - Major depression is a prevalent emotion disorder. Chronic stressful life in genetically susceptible individuals is presumably a major etiology that leads to neuron and synapse atrophy in the limbic system. Molecular mechanisms underlying the pathological changes remain elusive. Mice were treated by chronic unpredictable mild stress (CUMS) until they demonstrated depression-like behavior. GABA release in the medial prefrontal cortex was evaluated by cell electrophysiology and imaging. Molecular profiles related to GABA synthesis and uptake were investigated by the high-throughput sequencings of microRNAs and mRNAs as well as western blot analysis in this cortical area. In CUMS-induced depression mice, there appear the decreases in the innervation and function of GABAergic axons and in the levels of mRNAs and proteins of glutamate decarboxylase-67, vesicular GABA transporter and GABA transporter-3. miRNA-15b 5p, miRNA-144-3p, miRNA-582-5p and miRNA-879-5p that directly downregulate such mRNAs increase in this cortex. Our results suggest that chronic mild stress impairs GABA release and uptake by upregulating miRNAs and downregulating mRNAs and proteins, which may constitute the subcellular and molecular mechanisms for the lowered GABA tone in major depression. PMID- 27701407 TI - Gene expression alterations related to mania and psychosis in peripheral blood of patients with a first episode of psychosis. AB - Psychotic disorders affect ~3% of the general population and are among the most severe forms of mental diseases. In early stages of psychosis, clinical aspects may be difficult to distinguish from one another. Undifferentiated psychopathology at the first-episode of psychosis (FEP) highlights the need for biomarkers that can improve and refine differential diagnosis. We investigated gene expression differences between patients with FEP-schizophrenia spectrum (SCZ; N=53) or FEP-Mania (BD; N=16) and healthy controls (N=73). We also verified whether gene expression was correlated to severity of psychotic, manic, depressive symptoms and/or functional impairment. All participants were antipsychotic-naive. After the psychiatric interview, blood samples were collected and the expression of 12 psychotic-disorder-related genes was evaluated by quantitative PCR. AKT1 and DICER1 expression levels were higher in BD patients compared with that in SCZ patients and healthy controls, suggesting that expression of these genes is associated more specifically to manic features. Furthermore, MBP and NDEL1 expression levels were higher in SCZ and BD patients than in healthy controls, indicating that these genes are psychosis related (independent of diagnosis). No correlation was found between gene expression and severity of symptoms or functional impairment. Our findings suggest that genes related to neurodevelopment are altered in psychotic disorders, and some might support the differential diagnosis between schizophrenia and bipolar disorder, with a potential impact on the treatment of these disorders. PMID- 27701408 TI - Enhanced sensitivity to drugs of abuse and palatable foods following maternal overnutrition. AB - Epidemiological studies have shown an association between maternal overnutrition and increased risk of the progeny for the development of obesity as well as psychiatric disorders. Animal studies have shown results regarding maternal high fat diet (HFD) and a greater risk of the offspring to develop obesity. However, it still remains unknown whether maternal HFD can program the central reward system in such a way that it will imprint long-term changes that will predispose the offspring to addictive-like behaviors that may lead to obesity. We exposed female dams to either laboratory chow or HFD for a period of 9 weeks: 3 weeks before conception, during gestation and lactation. Offspring born to either control or HFD-exposed dams were examined in behavioral, neurochemical, neuroanatomical, metabolic and positron emission tomography (PET) scan tests. Our results demonstrate that HFD offspring compared with controls consume more alcohol, exhibit increased sensitivity to amphetamine and show greater conditioned place preference to cocaine. In addition, maternal HFD leads to increased preference to sucrose as well as to HFD while leaving the general feeding behavior intact. The hedonic behavioral alterations are accompanied by reduction of striatal dopamine and by increased dopamine 2 receptors in the same brain region as evaluated by post-mortem neurochemical, immunohistochemical as well as PET analyses. Taken together, our data suggest that maternal overnutrition predisposes the offspring to develop hedonic-like behaviors to both drugs of abuse as well as palatable foods and that these types of behaviors may share common neuronal underlying mechanisms that can lead to obesity. PMID- 27701409 TI - RGS2 expression predicts amyloid-beta sensitivity, MCI and Alzheimer's disease: genome-wide transcriptomic profiling and bioinformatics data mining. AB - Alzheimer's disease (AD) is the most frequent cause of dementia. Misfolded protein pathological hallmarks of AD are brain deposits of amyloid-beta (Abeta) plaques and phosphorylated tau neurofibrillary tangles. However, doubts about the role of Abeta in AD pathology have been raised as Abeta is a common component of extracellular brain deposits found, also by in vivo imaging, in non-demented aged individuals. It has been suggested that some individuals are more prone to Abeta neurotoxicity and hence more likely to develop AD when aging brains start accumulating Abeta plaques. Here, we applied genome-wide transcriptomic profiling of lymphoblastoid cells lines (LCLs) from healthy individuals and AD patients for identifying genes that predict sensitivity to Abeta. Real-time PCR validation identified 3.78-fold lower expression of RGS2 (regulator of G-protein signaling 2; P=0.0085) in LCLs from healthy individuals exhibiting high vs low Abeta sensitivity. Furthermore, RGS2 showed 3.3-fold lower expression (P=0.0008) in AD LCLs compared with controls. Notably, RGS2 expression in AD LCLs correlated with the patients' cognitive function. Lower RGS2 expression levels were also discovered in published expression data sets from postmortem AD brain tissues as well as in mild cognitive impairment and AD blood samples compared with controls. In conclusion, Abeta sensitivity phenotyping followed by transcriptomic profiling and published patient data mining identified reduced peripheral and brain expression levels of RGS2, a key regulator of G-protein-coupled receptor signaling and neuronal plasticity. RGS2 is suggested as a novel AD biomarker (alongside other genes) toward early AD detection and future disease modifying therapeutics. PMID- 27701410 TI - Brain-derived neurotrophic factor protects against tau-related neurodegeneration of Alzheimer's disease. AB - Reduced expression of brain-derived neurotrophic factor (BDNF) has a crucial role in the pathogenesis of Alzheimer's disease (AD), which is characterized with the formation of neuritic plaques consisting of amyloid-beta (Abeta) and neurofibrillary tangles composed of hyperphosphorylated tau protein. A growing body of evidence indicates a potential protective effect of BDNF against Abeta induced neurotoxicity in AD mouse models. However, the direct therapeutic effect of BDNF supplement on tauopathy in AD remains to be established. Here, we found that the BDNF level was reduced in the serum and brain of AD patients and P301L transgenic mice (a mouse model of tauopathy). Intralateral ventricle injection of adeno-associated virus carrying the gene encoding human BDNF (AAV-BDNF) achieved stable expression of BDNF gene and restored the BDNF level in the brains of P301L mice. Restoration of the BDNF level attenuated behavioral deficits, prevented neuron loss, alleviated synaptic degeneration and reduced neuronal abnormality, but did not affect tau hyperphosphorylation level in the brains of P301L mice. Long-term expression of AAV-BDNF in the brain was well tolerated by the mice. These findings suggest that the gene delivery of BDNF is a promising treatment for tau-related neurodegeneration for AD and other neurodegenerative disorders with tauopathy.

AB - Social insects make elaborate use of simple mechanisms to achieve seemingly complex behavior and may thus provide a unique resource to discover the basic cognitive elements required for culture, i.e., group-specific behaviors that spread from "innovators" to others in the group via social learning. We first explored whether bumblebees can learn a nonnatural object manipulation task by using string pulling to access a reward that was presented out of reach. Only a small minority "innovated" and solved the task spontaneously, but most bees were able to learn to pull a string when trained in a stepwise manner. In addition, naive bees learnt the task by observing a trained demonstrator from a distance. Learning the behavior relied on a combination of simple associative mechanisms and trial-and-error learning and did not require "insight": naive bees failed a "coiled-string experiment," in which they did not receive instant visual feedback of the target moving closer when tugging on the string. In cultural diffusion experiments, the skill spread rapidly from a single knowledgeable individual to the majority of a colony's foragers. We observed that there were several sequential sets ("generations") of learners, so that previously naive observers could first acquire the technique by interacting with skilled individuals and, subsequently, themselves become demonstrators for the next "generation" of learners, so that the longevity of the skill in the population could outlast the lives of informed foragers. This suggests that, so long as animals have a basic toolkit of associative and motor learning processes, the key ingredients for the cultural spread of unusual skills are already in place and do not require sophisticated cognition.

PMID- 27701413 TI - Neuropsin Inactivation Has Protective Effects against Depressive-Like Behaviours and Memory Impairment Induced by Chronic Stress. AB - Mounting evidence suggests the interaction between stress and genetics contribute to the development of depressive symptoms. Currently, the molecular mechanisms mediating this process are poorly understood, hindering the development of new clinical interventions. Here, we investigate the interaction between neuropsin, a serine protease, and chronic stress on the development of depressive-like behaviours in mice. We found no difference in baseline behaviour between neuropsin knockout and wild-type mice. However, our results show that neuropsin knockout mice are protected against the development of depressive-like behaviours and memory impairment following chronic stress. We hypothesised that this difference in behaviour may be due to an interaction between neuropsin and elevated plasma corticosterone. To test this, we subjected mice to chronic corticosterone injections. These injections resulted in changes to hippocampal structure similar to that observed following chronic stress. We found that inactivation of neuropsin limits the extent of these anatomical changes in both the chronic stress and the corticosterone injection exposed cohorts. We next used viral vectors to knockdown or overexpress neuropsin in the hippocampus to confirm the results of the KO study. Additionally, we found that inactivation of neuropsin limited glutamate dysregulation, associated with increased generation of reactive oxygen species, resulting from prolonged elevated plasma corticosterone. In this study, we demonstrate that neuropsin inactivation protects against the impairment of hippocampal functions and the depressive-like behaviour induced by chronic stress or high levels of corticosterone. Consequently, we suggest neuropsin is a potential target for clinical interventions for the management of stress disorders. PMID- 27701415 TI - A Prospective Study of Comparing Multi-Gene Biomarker Chip and Serum Carcinoembryonic Antigen in the Postoperative Surveillance for Patients with Stage I-III Colorectal Cancer. AB - BACKGROUND: Circulating biomarkers can predict clinical outcomes in colorectal cancer patients. The aim of the study was to evaluate the feasibility of our multigene biomarker chip for detecting circulating tumor cells for postoperative surveillance of stage I-III colorectal cancer patients. MATERIALS AND METHODS: In total, 298 stage I-III colorectal cancer patients were analyzed after curative resection between June 2010 and October 2014. During each follow-up, a postoperative surveillance strategy, including ESMO Guidelines Working Group recommendations and the biochip, was used. RESULTS: After a 28.4-month median follow-up, 48 (16.1%) patients had postoperative relapse. Univariate analysis revealed that the postoperative relapse risk factors were rectal tumor, perineural invasion, elevated preoperative and postoperative serum carcinoembryonic antigen levels, and positive biochip results (all P < 0.05). Multivariate analyses revealed that postoperative relapse correlated significantly with elevated postoperative serum carcinoembryonic antigen levels (odds ratio = 4.136, P = 0.008) and positive biochip results (odds ratio = 66.878, P < 0.001). However, the sensitivity (P = 0.003), specificity (P = 0.003), positive (P = 0.002) and negative (P = 0.006) predictive values, and accuracy (P < 0.001) of the biochip for predicting postoperative relapse were significantly higher than those of elevated postoperative serum carcinoembryonic antigen levels. Moreover, the median lead time between positive biochip result and postoperative relapse detection was significantly earlier than that between elevated postoperative serum carcinoembryonic antigen level and postoperative relapse detection (10.7 vs. 2.8 months, P < 0.001). Furthermore, positive biochip results correlated strongly with lower disease-free survival and overall survival of colorectal cancer patients (both P < 0.001). CONCLUSION: Compared with conventional serum carcinoembryonic antigen detection, our multigene chip aided more accurate and earlier prediction of postoperative relapse during stage I-III colorectal cancer patient surveillance. In clinical practice, this biochip may facilitate early postoperative relapse diagnosis in colorectal cancer patients.

AB - BACKGROUND: Clinical presentation phenotypes of obstructive sleep apnoea (OSA) and their association with comorbidity as well as impact on adherence to continuous positive airway pressure (CPAP) treatment have not been established. METHODS: A prospective follow-up cohort of adult patients with OSA (apnoea hypopnoea index (AHI) of >=5/h) from 17 European countries and Israel (n = 6,555) was divided into four clinical presentation phenotypes based on daytime symptoms labelled as excessive daytime sleepiness ("EDS") and nocturnal sleep problems other than OSA (labelled as "insomnia"): 1) EDS (daytime+/nighttime-), 2) EDS/insomnia (daytime+/nighttime+), 3) non-EDS/non-insomnia (daytime-/nighttime ), 4) and insomnia (daytime-/nighttime+) phenotype. RESULTS: The EDS phenotype comprised 20.7%, the non-EDS/non-insomnia type 25.8%, the EDS/insomnia type 23.7%, and the insomnia phenotype 29.8% of the entire cohort. Thus, clinical presentation phenotypes with insomnia symptoms were dominant with 53.5%, but only 5.6% had physician diagnosed insomnia. Cardiovascular comorbidity was less prevalent in the EDS and most common in the insomnia phenotype (48.9% vs. 56.8%, p<0.001) despite more severe OSA in the EDS group (AHI 35.0+/-25.5/h vs. 27.9+/ 22.5/h, p<0.001, respectively). Psychiatric comorbidity was associated with insomnia like OSA phenotypes independent of age, gender and body mass index (HR 1.5 (1.188-1.905), p<0.001). The EDS phenotype tended to associate with higher CPAP usage (22.7 min/d, p = 0.069) when controlled for age, gender, BMI and sleep apnoea severity. CONCLUSIONS: Phenotypes with insomnia symptoms comprised more than half of OSA patients and were more frequently linked with comorbidity than those with EDS, despite less severe OSA. CPAP usage was slightly higher in phenotypes with EDS. PMID- 27701418 TI - Role of Recruitment Processes in Structuring Coralligenous Benthic Assemblages in the Northern Adriatic Continental Shelf. AB - Coralligenous biogenic reefs are among the most diverse marine habitats in the Mediterranean Sea. The northern Adriatic mesophotic coralligenous outcrops host very rich and diverse epibenthic assemblages. Several studies quantified the low temporal variability and high spatial heterogeneity of these habitats, while processes driving structuring and differentiation are still poorly understood. To shed light on these processes, temporal and spatial patterns of colonisation were investigated using travertine tiles deployed on three coralligenous outcrops, corresponding to the main typologies of benthic assemblages described in previous studies. Three years after deployment, assemblages colonising travertine tiles resembled the differentiation among sites revealed by the natural assemblages in terms of major ecological groups. Processes structuring and maintaining species diversity have been explored. Pioneer species with high reproduction rate, long distance larval dispersal and fast growth (e.g. the serpulid polychaete Spirobranchus triqueter and the bivalve Anomia ephippium), were the most abundant in the early stages of recruitment on the two outcrops further away from the coast and with lower sedimentation. Their success may vary according to larval availability and environmental conditions (e.g., sedimentation rates). At these sites early-stage lasted 10-12 months, during which even species from natural substrates began colonising tiles by settlement of planktonic propagules (e.g., encrusting calcareous Rhodophyta) and lateral encroachment (e.g., sponges and ascidians). On coastal outcrop, exposed to a higher sedimentation rates, tiles were colonised by fast-growing algal turfs. Resilience of northern Adriatic coralligenous assemblages, and maintenance of their diversity, appeared largely entrusted to asexual reproduction. Exploring the mechanisms that underlie the formation and maintenance of the species diversity is crucial to improve our understanding of ecological processes and to implement appropriate conservation strategies of the Adriatic coralligenous reefs.

AB - Pyrophosphate is a potent mitogen, capable of stimulating proliferation in multiple cell types, and a critical participant in bone mineralization. Pyrophosphate can also affect the resorption rate and bioactivity of orthopedic ceramics. The present study investigated whether calcium pyrophosphate affected proliferation, differentiation and gene expression in early (MC3T3 pre osteoblast) and late stage (SAOS-2 osteosarcoma) osteoblasts. Pyrophosphate stimulated peak alkaline phosphatase activity by 50% and 150% at 100MUM and 0.1MUM in MC3T3, and by 40% in SAOS-2. The expression of differentiation markers collagen 1 (COL1), alkaline phosphatase (ALP), osteopontin (OPN), and osteocalcin (OCN) were increased by an average of 1.5, 2, 2 and 3 fold, by high concentrations of sodium pyrophosphate (100MUM) after 7 days of exposure in MC3T3. COX-2 and ANK expression did not differ significantly from controls in either treatment group. Though both high and low concentrations of pyrophosphate stimulate ALP activity, only high concentrations (100MUM) stimulated osteogenic gene expression. Pyrophosphate did not affect proliferation in either cell type. The results of this study confirm that chronic exposure to pyrophosphate exerts a physiological effect upon osteoblast differentiation and ALP activity, specifically by stimulating osteoblast differentiation markers and extracellular matrix gene expression.

AB - BACKGROUND: Life expectancy at birth in the United States will likely surpass 80 years in the coming decade. Yet recent studies suggest that longevity gains are unevenly shared across age and socioeconomic groups. First, mortality in midlife has risen among non-Hispanic whites. Second, low-educated whites have suffered stalls (men) or declines (women) in adult life expectancy, which is significantly lower than among their college-educated counterparts. Estimating the number of life years lost or gained by age and cause of death, broken down by educational attainment, is crucial in identifying vulnerable populations. METHODS AND FINDINGS: Using U.S. vital statistics data from 1990 to 2010, this study decomposes the change in life expectancy at age 25 by age and cause of death across educational attainment groups, broken down by race and gender. The findings reveal that mortality in midlife increased for white women (and to a lesser extent men) with 12 or fewer years of schooling, accounting for most of the stalls or declines in adult life expectancy observed in those groups. Among blacks, mortality declined in nearly all age and educational attainment groups. Although an educational gradient was found across multiple causes of death, between 60 and 80 percent of the gap in adult life expectancy was explained by cardiovascular diseases, smoking-related diseases, and external causes of death. Furthermore, the number of life years lost to smoking-related, external, and other causes of death increased among low- and high school-educated whites, explaining recent stalls or declines in longevity. CONCLUSIONS: Large segments of the American population-particularly low- and high school-educated whites under age 55-are diverging from their college-educated counterparts and losing additional years of life to smoking-related diseases and external causes of death. If this trend continues, old-age mortality may also increase for these birth cohorts in the coming decades. PMID- 27701420 TI - Characterization of Novel Antimalarial Compound ACT-451840: Preclinical Assessment of Activity and Dose-Efficacy Modeling. AB - BACKGROUND: Artemisinin resistance observed in Southeast Asia threatens the continued use of artemisinin-based combination therapy in endemic countries. Additionally, the diversity of chemical mode of action in the global portfolio of marketed antimalarials is extremely limited. Addressing the urgent need for the development of new antimalarials, a chemical class of potent antimalarial compounds with a novel mode of action was recently identified. Herein, the preclinical characterization of one of these compounds, ACT-451840, conducted in partnership with academic and industrial groups is presented. METHOD AND FINDINGS: The properties of ACT-451840 are described, including its spectrum of activities against multiple life cycle stages of the human malaria parasite Plasmodium falciparum (asexual and sexual) and Plasmodium vivax (asexual) as well as oral in vivo efficacies in two murine malaria models that permit infection with the human and the rodent parasites P. falciparum and Plasmodium berghei, respectively. In vitro, ACT-451840 showed a 50% inhibition concentration of 0.4 nM (standard deviation [SD]: +/- 0.0 nM) against the drug-sensitive P. falciparum NF54 strain. The 90% effective doses in the in vivo efficacy models were 3.7 mg/kg against P. falciparum (95% confidence interval: 3.3-4.9 mg/kg) and 13 mg/kg against P. berghei (95% confidence interval: 11-16 mg/kg). ACT-451840 potently prevented male gamete formation from the gametocyte stage with a 50% inhibition concentration of 5.89 nM (SD: +/- 1.80 nM) and dose-dependently blocked oocyst development in the mosquito with a 50% inhibitory concentration of 30 nM (range: 23-39). The compound's preclinical safety profile is presented and is in line with the published results of the first-in-man study in healthy male participants, in whom ACT-451840 was well tolerated. Pharmacokinetic/pharmacodynamic (PK/PD) modeling was applied using efficacy in the murine models (defined either as antimalarial activity or as survival) in relation to area under the concentration versus time curve (AUC), maximum observed plasma concentration (Cmax), and time above a threshold concentration. The determination of the dose-efficacy relationship of ACT-451840 under curative conditions in rodent malaria models allowed prediction of the human efficacious exposure. CONCLUSION: The dual activity of ACT-451840 against asexual and sexual stages of P. falciparum and the activity on P. vivax have the potential to meet the specific profile of a target compound that could replace the fast-acting artemisinin component and harbor additional gametocytocidal activity and, thereby, transmission-blocking properties. The fast parasite reduction ratio (PRR) and gametocytocidal effect of ACT-451840 were recently also confirmed in a clinical proof-of-concept (POC) study. PMID- 27701421 TI - Cardio-Thoracic Ratio Is Stable, Reproducible and Has Potential as a Screening Tool for HIV-1 Related Cardiac Disorders in Resource Poor Settings. AB - BACKGROUND: Cardiovascular disorders are common in HIV-1 infected persons in Africa and presentation is often insidious. Development of screening algorithms for cardiovascular disorders appropriate to a resource-constrained setting could facilitate timely referral. Cardiothoracic ratio (CTR) on chest radiograph (CXR) has been suggested as a potential screening tool but little is known about its reproducibility and stability. Our primary aim was to evaluate the stability and the inter-observer variability of CTR in HIV-1 infected outpatients. We further evaluated the prevalence of cardiomegaly (CTR>=0.5) and its relationship with other risk factors in this population. METHODOLOGY: HIV-1 infected participants were identified during screening for a tuberculosis vaccine trial in Khayelitsha, South Africa between August 2011 and April 2012. Participants had a digital posterior-anterior CXR performed as well as history, examination and baseline observations. CXRs were viewed using OsiriX software and CTR calculated using digital callipers. RESULTS: 450 HIV-1-infected adults were evaluated, median age 34 years (IQR 30-40) with a CD4 count 566/mm3 (IQR 443-724), 70% on antiretroviral therapy (ART). The prevalence of cardiomegaly was 12.7% (95% C.I. 9.6%-15.8%). CTR was calculated by a 2nd reader for 113 participants, measurements were highly correlated r = 0.95 (95% C.I. 0.93-0.97) and agreement of cardiomegaly substantial kappa = 0.78 (95% C.I 0.61-0.95). CXR were repeated in 51 participants at 4-12 weeks, CTR measurements between the 2 time points were highly correlated r = 0.77 (95% C.I 0.68-0.88) and agreement of cardiomegaly excellent kappa = 0.92 (95% C.I. 0.77-1). Participants with cardiomegaly had a higher median BMI (31.3; IQR 27.4-37.4) versus 26.9; IQR 23.2-32.4); p<0.0001) and median systolic blood pressure (130; IQR 121-141 versus 125; IQR 117-135; p = 0.01). CONCLUSION: CTR is a robust measurement, stable over time with substantial inter-observer agreement. A prospective study evaluating utility of CXR to identify cardiovascular disorder in this population is warranted. PMID- 27701422 TI - Differential Responses of Post-Exercise Recovery of Leg Blood Flow and Oxygen Uptake Kinetics in HFpEF versus HFrEF. AB - The goals of the current study were to compare leg blood flow, oxygen extraction and oxygen uptake (VO2) after constant load sub-maximal unilateral knee extension (ULKE) exercise in patients with heart failure with reduced ejection fraction (HFrEF) compared to those with preserved ejection fraction (HFpEF). Previously, it has been shown that prolonged whole body VO2 recovery kinetics are directly related to disease severity and all-cause mortality in HFrEF patients. To date, no study has simultaneously measured muscle-specific blood flow and oxygen extraction post exercise recovery kinetics in HFrEF or HFpEF patients; therefore it is unknown if muscle VO2 recovery kinetics, and more specifically, the recovery kinetics of blood flow and oxygen extraction at the level of the muscle, differ between HF phenotypes. Ten older (68+/-10yrs) HFrEF (n = 5) and HFpEF (n = 5) patients performed sub-maximal (85% of maximal weight lifted during an incremental test) ULKE exercise for 4 minutes. Femoral venous blood flow and venous O2 saturation were measured continuously from the onset of end-exercise, using a novel MRI method, to determine off-kinetics (mean response times, MRT) for leg VO2 and its determinants. HFpEF and HFrEF patients had similar end exercise leg blood flow (1.1+/-0.6 vs. 1.2+/-0.6 L/min, p>0.05), venous saturation (42+/-12 vs. 41+/-11%, p>0.05) and VO2 (0.13+/-0.08 vs. 0.11+/-0.05 L/min, p>0.05); however HFrEF had significantly delayed recovery MRT for flow (292+/-135sec. vs 105+/-63sec., p = 0.004) and VO2 (95+/-37sec. vs. 47+/-15sec., p = 0.005) compared to HFpEF. Impaired muscle VO2 recovery kinetics following ULKE exercise differentiated HFrEF from HFpEF patients and suggests distinct underlying pathology and potential therapeutic approaches in these populations. PMID- 27701423 TI - Whole Genome Sequence Analysis of a Large Isoniazid-Resistant Tuberculosis Outbreak in London: A Retrospective Observational Study. AB - BACKGROUND: A large isoniazid-resistant tuberculosis outbreak centred on London, United Kingdom, has been ongoing since 1995. The aim of this study was to investigate the power and value of whole genome sequencing (WGS) to resolve the transmission network compared to current molecular strain typing approaches, including analysis of intra-host diversity within a specimen, across body sites, and over time, with identification of genetic factors underlying the epidemiological success of this cluster. METHODS AND FINDINGS: We sequenced 344 outbreak isolates from individual patients collected over 14 y (2 February 1998 22 June 2012). This demonstrated that 96 (27.9%) were indistinguishable, and only one differed from this major clone by more than five single nucleotide polymorphisms (SNPs). The maximum number of SNPs between any pair of isolates was nine SNPs, and the modal distance between isolates was two SNPs. WGS was able to reveal the direction of transmission of tuberculosis in 16 cases within the outbreak (4.7%), including within a multidrug-resistant cluster that carried a rare rpoB mutation associated with rifampicin resistance. Eleven longitudinal pairs of patient pulmonary isolates collected up to 48 mo apart differed from each other by between zero and four SNPs. Extrapulmonary dissemination resulted in acquisition of a SNP in two of five cases. WGS analysis of 27 individual colonies cultured from a single patient specimen revealed ten loci differed amongst them, with a maximum distance between any pair of six SNPs. A limitation of this study, as in previous studies, is that indels and SNPs in repetitive regions were not assessed due to the difficulty in reliably determining this variation. CONCLUSIONS: Our study suggests that (1) certain paradigms need to be revised, such as the 12 SNP distance as the gold standard upper threshold to identify plausible transmissions; (2) WGS technology is helpful to rule out the possibility of direct transmission when isolates are separated by a substantial number of SNPs; (3) the concept of a transmission chain or network may not be useful in institutional or household settings; (4) the practice of isolating single colonies prior to sequencing is likely to lead to an overestimation of the number of SNPs between cases resulting from direct transmission; and (5) despite appreciable genomic diversity within a host, transmission of tuberculosis rarely results in minority variants becoming dominant. Thus, whilst WGS provided some increased resolution over variable number tandem repeat (VNTR)-based clustering, it was insufficient for inferring transmission in the majority of cases. PMID- 27701425 TI - Population Immunity against Serotype-2 Poliomyelitis Leading up to the Global Withdrawal of the Oral Poliovirus Vaccine: Spatio-temporal Modelling of Surveillance Data. AB - BACKGROUND: Global withdrawal of serotype-2 oral poliovirus vaccine (OPV2) took place in April 2016. This marked a milestone in global polio eradication and was a public health intervention of unprecedented scale, affecting 155 countries. Achieving high levels of serotype-2 population immunity before OPV2 withdrawal was critical to avoid subsequent outbreaks of serotype-2 vaccine-derived polioviruses (VDPV2s). METHODS AND FINDINGS: In August 2015, we estimated vaccine induced population immunity against serotype-2 poliomyelitis for 1 January 2004 30 June 2015 and produced forecasts for April 2016 by district in Nigeria and Pakistan. Population immunity was estimated from the vaccination histories of children <36 mo old identified with non-polio acute flaccid paralysis (AFP) reported through polio surveillance, information on immunisation activities with different oral poliovirus vaccine (OPV) formulations, and serotype-specific estimates of the efficacy of these OPVs against poliomyelitis. District immunity estimates were spatio-temporally smoothed using a Bayesian hierarchical framework. Coverage estimates for immunisation activities were also obtained, allowing for heterogeneity within and among districts. Forward projections of immunity, based on these estimates and planned immunisation activities, were produced through to April 2016 using a cohort model. Estimated population immunity was negatively correlated with the probability of VDPV2 poliomyelitis being reported in a district. In Nigeria and Pakistan, declines in immunity during 2008-2009 and 2012-2013, respectively, were associated with outbreaks of VDPV2. Immunity has since improved in both countries as a result of increased use of trivalent OPV, and projections generally indicated sustained or improved immunity in April 2016, such that the majority of districts (99% [95% uncertainty interval 97%-100%] in Nigeria and 84% [95% uncertainty interval 77%-91%] in Pakistan) had >70% population immunity among children <36 mo old. Districts with lower immunity were clustered in northeastern Nigeria and northwestern Pakistan. The accuracy of immunity estimates was limited by the small numbers of non-polio AFP cases in some districts, which was reflected by large uncertainty intervals. Forecasted improvements in immunity for April 2016 were robust to the uncertainty in estimates of baseline immunity (January-June 2015), vaccine coverage, and vaccine efficacy. CONCLUSIONS: Immunity against serotype-2 poliomyelitis was forecasted to improve in April 2016 compared to the first half of 2015 in Nigeria and Pakistan. These analyses informed the endorsement of OPV2 withdrawal in April 2016 by the WHO Strategic Advisory Group of Experts on Immunization. PMID- 27701426 TI - Coupled Hybrid Continuum-Discrete Model of Tumor Angiogenesis and Growth. AB - The processes governing tumor growth and angiogenesis are codependent. To study the relationship between them, we proposed a coupled hybrid continuum-discrete model. In this model, tumor cells, their microenvironment (extracellular matrixes, matrix-degrading enzymes, and tumor angiogenic factors), and their network of blood vessels, described by a series of discrete points, were considered. The results of numerical simulation reveal the process of tumor growth and the change in microenvironment from avascular to vascular stage, indicating that the network of blood vessels develops gradually as the tumor grows. Our findings also reveal that a tumor is divided into three regions: necrotic, semi-necrotic, and well-vascularized. The results agree well with the previous relevant studies and physiological facts, and this model represents a platform for further investigations of tumor therapy. PMID- 27701424 TI - Novel Genetic Variants for Cartilage Thickness and Hip Osteoarthritis. AB - Osteoarthritis is one of the most frequent and disabling diseases of the elderly. Only few genetic variants have been identified for osteoarthritis, which is partly due to large phenotype heterogeneity. To reduce heterogeneity, we here examined cartilage thickness, one of the structural components of joint health. We conducted a genome-wide association study of minimal joint space width (mJSW), a proxy for cartilage thickness, in a discovery set of 13,013 participants from five different cohorts and replication in 8,227 individuals from seven independent cohorts. We identified five genome-wide significant (GWS, P<=5.0*10 8) SNPs annotated to four distinct loci. In addition, we found two additional loci that were significantly replicated, but results of combined meta-analysis fell just below the genome wide significance threshold. The four novel associated genetic loci were located in/near TGFA (rs2862851), PIK3R1 (rs10471753), SLBP/FGFR3 (rs2236995), and TREH/DDX6 (rs496547), while the other two (DOT1L and SUPT3H/RUNX2) were previously identified. A systematic prioritization for underlying causal genes was performed using diverse lines of evidence. Exome sequencing data (n = 2,050 individuals) indicated that there were no rare exonic variants that could explain the identified associations. In addition, TGFA, FGFR3 and PIK3R1 were differentially expressed in OA cartilage lesions versus non lesioned cartilage in the same individuals. In conclusion, we identified four novel loci (TGFA, PIK3R1, FGFR3 and TREH) and confirmed two loci known to be associated with cartilage thickness.The identified associations were not caused by rare exonic variants. This is the first report linking TGFA to human OA, which may serve as a new target for future therapies. PMID- 27701427 TI - Asymmetric Power Boosts Extortion in an Economic Experiment. AB - Direct reciprocity is a major mechanism for the evolution of cooperation. Several classical studies have suggested that humans should quickly learn to adopt reciprocal strategies to establish mutual cooperation in repeated interactions. On the other hand, the recently discovered theory of ZD strategies has found that subjects who use extortionate strategies are able to exploit and subdue cooperators. Although such extortioners have been predicted to succeed in any population of adaptive opponents, theoretical follow-up studies questioned whether extortion can evolve in reality. However, most of these studies presumed that individuals have similar strategic possibilities and comparable outside options, whereas asymmetries are ubiquitous in real world applications. Here we show with a model and an economic experiment that extortionate strategies readily emerge once subjects differ in their strategic power. Our experiment combines a repeated social dilemma with asymmetric partner choice. In our main treatment there is one randomly chosen group member who is unilaterally allowed to exchange one of the other group members after every ten rounds of the social dilemma. We find that this asymmetric replacement opportunity generally promotes cooperation, but often the resulting payoff distribution reflects the underlying power structure. Almost half of the subjects in a better strategic position turn into extortioners, who quickly proceed to exploit their peers. By adapting their cooperation probabilities consistent with ZD theory, extortioners force their co players to cooperate without being similarly cooperative themselves. Comparison to non-extortionate players under the same conditions indicates a substantial net gain to extortion. Our results thus highlight how power asymmetries can endanger mutually beneficial interactions, and transform them into exploitative relationships. In particular, our results indicate that the extortionate strategies predicted from ZD theory could play a more prominent role in our daily interactions than previously thought. PMID- 27701428 TI - Krill Oil Improves Mild Knee Joint Pain: A Randomized Control Trial. AB - BACKGROUND: Krill oil is an edible oil extracted from krill, a small red-colored crustacean found in the Antarctic Ocean. The administration of krill oil is reported to mitigate inflammation in patients with cardiac disease, rheumatoid arthritis, or osteoarthritis. However, the effect of krill oil on mild knee pain has not yet been determined. OBJECTIVE: To assess the effect of krill oil on mild knee pain. DESIGN: A randomized, double-blind, parallel-group, placebo-controlled trial of fifty adults (38-85 years old) with mild knee pain attending the Fukushima Orthopedic Clinic (Tochigi, Japan) between September 2014 and March 2015. INTERVENTIONS: Participants were randomized to receive 2 g per day of either krill oil or an identical placebo for 30 days. OUTCOMES: The primary outcome was improvement in subjective symptoms of knee pain as assessed by the Japanese Knee Osteoarthritis Measure (JKOM) and Japanese Orthopaedic Association score (JOA). Secondary outcomes included blood and urine biochemical parameters. RESULTS: Both the placebo and krill oil groups showed significant improvements in the questions in the JKOM and JOA questionnaires after administration. After the intervention, krill oil group showed more improvements than placebo group in two questions regarding the pain and stiffness in knees in JKOM. Controlling for age, sex, weight, and smoking and drinking habits, krill oil significantly mitigated knee pain in sleeping (P < 0.001), standing (P < 0.001) and the range of motion of both right and left knees (both P = 0.011) compared to placebo. Krill oil administration raised plasma EPA (P = 0.048) and EPA/AA ratio (P = 0.003). CONCLUSION: This study indicates that krill oil administration (2 g/day, 30 days) improved the subjective symptoms of knee pain in adults with mild knee pain. TRIAL REGISTRATION: UMIN-CTR; ID UMIN000014413. PMID- 27701429 TI - The Global Diversity of Hemichordata. AB - Phylum Hemichordata, composed of worm-like Enteropneusta and colonial Pterobranchia, has been reported to only contain about 100 species. However, recent studies of hemichordate phylogeny and taxonomy suggest the species number has been largely underestimated. One issue is that species must be described by experts, and historically few taxonomists have studied this group of marine invertebrates. Despite this previous lack of coverage, interest in hemichordates has piqued in the past couple of decades, as they are critical to understanding the evolution of chordates-as acorn worms likely resemble the deuterostome ancestor more closely than any other extant animal. This review provides an overview of our current knowledge of hemichordates, focusing specifically on their global biodiversity, geographic distribution, and taxonomy. Using information available in the World Register of Marine Species and published literature, we assembled a list of 130 described, extant species. The majority (83%) of these species are enteropneusts, and more taxonomic descriptions are forthcoming. Ptychoderidae contained the greatest number of species (41 species), closely followed by Harrimaniidae (40 species), of the recognized hemichordate families. Hemichordates are found throughout the world's oceans, with the highest reported numbers by regions with marine labs and diligent taxonomic efforts (e.g. North Pacific and North Atlantic). Pterobranchs are abundant in Antarctica, but have also been found at lower latitudes. We consider this a baseline report and expect new species of Hemichordata will continue to be discovered and described as new marine habitats are characterized and explored. PMID- 27701430 TI - Empirical Models of Social Learning in a Large, Evolving Network. AB - This paper advances theories of social learning through an empirical examination of how social networks change over time. Social networks are important for learning because they constrain individuals' access to information about the behaviors and cognitions of other people. Using data on a large social network of mobile device users over a one-month time period, we test three hypotheses: 1) attraction homophily causes individuals to form ties on the basis of attribute similarity, 2) aversion homophily causes individuals to delete existing ties on the basis of attribute dissimilarity, and 3) social influence causes individuals to adopt the attributes of others they share direct ties with. Statistical models offer varied degrees of support for all three hypotheses and show that these mechanisms are more complex than assumed in prior work. Although homophily is normally thought of as a process of attraction, people also avoid relationships with others who are different. These mechanisms have distinct effects on network structure. While social influence does help explain behavior, people tend to follow global trends more than they follow their friends. PMID- 27701431 TI - The Effect of Age on Technique Variability and Outcome Variability during a Leg Press. AB - The aim of this study was to determine the effect of aging on power generation and joint coordination during a leg press, in order to increase understanding of how functional movements are affected during the aging process. 44 older and 24 younger adults performed eight sub-maximal power repetitions on a seated leg press dynamometer. Peak power and velocity (at 40% maximum resistance) were measured along with the coordination (coupling angle) of the lower limb joints using the vector coding technique. The younger adults produced significantly greater peak power than the older adults (mean +/- SD; 762 W +/- 245 vs 361 W +/- 162, p < 0.01) and at higher peak velocities (mean +/- SD; 1.37 m/s +/- 0.05 vs 1.00 m/s +/- 0.06, p < 0.01). The older adults produced less consistent values of peak power than younger adults, evidenced by a higher coefficient of variation (mean +/- SD; 7.6% +/- 5.2 vs 5.0% +/- 3.0, p < 0.01), however, there was significantly less variability in the coupling angles displayed by the older adults compared to the younger adults (mean +/- SD; 2.0 degrees +/- 1.1 vs 3.5 degrees +/- 2.7, p < 0.01 (ankle-knee); 1.7 degrees +/- 0.6 vs 4.1 degrees +/- 3.0, p < 0.01 (knee-hip)). The results of this study demonstrate that older adults display higher outcome variability but lower variability in technique (coordination). The more rigid movement strategies displayed by the older adults potentially reflects an increased risk of overuse injury due to repetitive demands on the same structures, or the reduced ability to respond to unexpected situations due to a lack of flexibility in joint control. PMID- 27701432 TI - Influence of Endogenous and Exogenous Estrogenic Endocrine on Intestinal Microbiota in Zebrafish. AB - Gender is one of the factors influencing the intestinal microbial composition in mammals, but whether fish also have gender-specific intestinal microbial patterns remains unknown. In this decade, endocrine disrupting chemicals in surface and ground water of many areas and increasing observation of freshwater male fish displaying female sexual characteristics have been reported. Here we identified the difference in intestinal microbiota between male and female zebrafish, and revealed the influence of endocrine disrupting chemicals on zebrafish intestinal microbiota by using high-throughput sequencing. The results indicated that Fusobacteria, Bacteroidetes and Proteobacteria were dominant in the gut of zebrafish and there were no obvious gender-specific intestinal microbial patterns. Two endocrine disrupting chemicals, Estradiol (E2) and Bisphenol A (BPA), were selected to treat male zebrafish for 5 weeks. E2 and BPA increased vitellogenin expression in the liver of male zebrafish and altered the intestinal microbial composition with the abundance of the phylum CKC4 increased significantly. Our results suggested that because of the developmental character and living environment, gender did not influence the assembly of intestinal microbiota in zebrafish as it does in mammals, but exposure extra to endocrine disrupting chemicals disturbed the intestinal microbial composition, which may be related to changes in host physiological metabolism. PMID- 27701433 TI - Strong or Weak Handgrip? Normative Reference Values for the German Population across the Life Course Stratified by Sex, Age, and Body Height. AB - Handgrip strength is an important biomarker of healthy ageing and a powerful predictor of future morbidity and mortality both in younger and older populations. Therefore, the measurement of handgrip strength is increasingly used as a simple but efficient screening tool for health vulnerability. This study presents normative reference values for handgrip strength in Germany for use in research and clinical practice. It is the first study to provide normative data across the life course that is stratified by sex, age, and body height. The study used a nationally representative sample of test participants ages 17-90. It was based on pooled data from five waves of the German Socio-Economic Panel (2006 2014) and involved a total of 11,790 persons living in Germany (providing 25,285 observations). Handgrip strength was measured with a Smedley dynamometer. Results showed that peak mean values of handgrip strength are reached in men's and women's 30s and 40s after which handgrip strength declines in linear fashion with age. Following published recommendations, the study used a cut-off at 2 SD below the sex-specific peak mean value across the life course to define a 'weak grip'. Less than 10% of women and men aged 65-69 were classified as weak according to this definition, shares increasing to about half of the population aged 80-90. Based on survival analysis that linked handgrip strength to a relevant outcome, however, a 'critically weak grip' that warrants further examination was estimated to commence already at 1 SD below the group-specific mean value.

The primary somatosensory cortex (SI) is involved in generating the proprioception by receiving peripheral sensory inputs from both cutaneous and muscle afferents. In particular, area 3a receives input from muscle afferents and areas 3b and 1 from cutaneous afferents. However, segregation of two sensory inputs to these cortical areas has not been evaluated quantitatively because of methodological difficulties in distinguishing the incoming signals. To overcome this, we applied electrical stimulation separately to two forearm nerves innervating muscle (deep radial nerve) and skin (superficial radial nerve), and examined the spatiotemporal distribution of sensory evoked potentials (SEPs) in SI of anaesthetized macaques. The SEPs arising from the deep radial nerve were observed exclusively at the bottom of central sulcus (CS), which was identified as area 3a using histological reconstruction. In contrast, SEPs evoked by stimulation of the superficial radial nerve were observed in the superficial part of SI, identified as areas 3b and 1. In addition to these earlier, larger potentials, we also found small and slightly delayed SEPs evoked by cutaneous nerve stimulation in area 3a. Coexistence of the SEPs from both deep and superficial radial nerves suggests that area 3a could integrate muscle and cutaneous signals to shape proprioception. PMID- 27701435 TI - Viral Inhibition of Bacterial Phagocytosis by Human Macrophages: Redundant Role of CD36. AB - Macrophages are essential to maintaining lung homoeostasis and recent work has demonstrated that influenza-infected lung macrophages downregulate their expression of the scavenger receptor CD36. This receptor has also been shown to be involved in phagocytosis of Streptococcus pneumoniae, a primary agent associated with pneumonia secondary to viral infection. The aim of this study was to investigate the role of CD36 in the effects of viral infection on macrophage phagocytic function. Human monocyte-derived macrophages (MDM) were exposed to H3N2 X31 influenza virus, M37 respiratory syncytial virus (RSV) or UV-irradiated virus. No infection of MDM was seen upon exposure to UV-irradiated virus but incubation with live X31 or M37 resulted in significant levels of viral detection by flow cytometry or RT-PCR respectively. Infection resulted in significantly diminished uptake of S. pneumoniae by MDM and significantly decreased expression of CD36 at both the cell surface and mRNA level. Concurrently, there was a significant increase in IFNbeta gene expression in response to infection and we observed a significant decrease in bacterial phagocytosis (p = 0.031) and CD36 gene expression (p = 0.031) by MDM cultured for 24 h in 50IU/ml IFNbeta. Knockdown of CD36 by siRNA resulted in decreased phagocytosis, but this was mimicked by transfection reagent alone. When MDM were incubated with CD36 blocking antibodies no effect on phagocytic ability was observed. These data indicate that autologous IFNbeta production by virally-infected cells can inhibit bacterial phagocytosis, but that decreased CD36 expression by these cells does not play a major role in this functional deficiency. PMID- 27701436 TI - hemaClass.org: Online One-By-One Microarray Normalization and Classification of Hematological Cancers for Precision Medicine. AB - BACKGROUND: Dozens of omics based cancer classification systems have been introduced with prognostic, diagnostic, and predictive capabilities. However, they often employ complex algorithms and are only applicable on whole cohorts of patients, making them difficult to apply in a personalized clinical setting. RESULTS: This prompted us to create hemaClass.org, an online web application providing an easy interface to one-by-one RMA normalization of microarrays and subsequent risk classifications of diffuse large B-cell lymphoma (DLBCL) into cell-of-origin and chemotherapeutic sensitivity classes. Classification results for one-by-one array pre-processing with and without a laboratory specific RMA reference dataset were compared to cohort based classifiers in 4 publicly available datasets. Classifications showed high agreement between one-by-one and whole cohort pre-processsed data when a laboratory specific reference set was supplied. The website is essentially the R-package hemaClass accompanied by a Shiny web application. The well-documented package can be used to run the website locally or to use the developed methods programmatically. CONCLUSIONS: The website and R-package is relevant for biological and clinical lymphoma researchers using affymetrix U-133 Plus 2 arrays, as it provides reliable and swift methods for calculation of disease subclasses. The proposed one-by-one pre processing method is relevant for all researchers using microarrays. PMID- 27701437 TI - A New Aspergillus fumigatus Typing Method Based on Hypervariable Tandem Repeats Located within Exons of Surface Protein Coding Genes (TRESP). AB - Aspergillus fumigatus is a saprotrophic mold fungus ubiquitously found in the environment and is the most common species causing invasive aspergillosis in immunocompromised individuals. For A. fumigatus genotyping, the short tandem repeat method (STRAf) is widely accepted as the first choice. However, difficulties associated with PCR product size and required technology have encouraged the development of novel typing techniques. In this study, a new genotyping method based on hypervariable tandem repeats within exons of surface protein coding genes (TRESP) was designed. A. fumigatus isolates were characterized by PCR amplification and sequencing with a panel of three TRESP encoding genes: cell surface protein A; MP-2 antigenic galactomannan protein; and hypothetical protein with a CFEM domain. The allele sequence repeats of each of the three targets were combined to assign a specific genotype. For the evaluation of this method, 126 unrelated A. fumigatus strains were analyzed and 96 different genotypes were identified, showing a high level of discrimination [Simpson's index of diversity (D) 0.994]. In addition, 49 azole resistant strains were analyzed identifying 26 genotypes and showing a lower D value (0.890) among them. This value could indicate that these resistant strains are closely related and share a common origin, although more studies are needed to confirm this hypothesis. In summary, a novel genotyping method for A. fumigatus has been developed which is reproducible, easy to perform, highly discriminatory and could be especially useful for studying outbreaks. PMID- 27701439 TI - Predictors and Extent of Institutional Trust in Government, Banks, the Media and Religious Organisations: Evidence from Cross-Sectional Surveys in Six Asia Pacific Countries. AB - BACKGROUND: Building or maintaining institutional trust is of central importance in democratic societies since negative experiences (potentially leading to mistrust) with government or other institutions may have a much more profound effect than positive experiences (potentially maintaining trust). Healthy democracy relies on more than simply trusting the national government of the time, and is mediated through other symbols of institutional power, such as the legal system, banks, the media and religious organisations. This paper focuses on institutional trust-the level and predictors of trust in some of the major institutions in society, namely politics, the media, banks, the legal system and religious organisations. We present analyses from a consolidated dataset containing data from six countries in the Asia Pacific region-Australia, Hong Kong, Japan, South Korea, Taiwan and Thailand. METHODS: Cross-sectional surveys were undertaken in each country in 2009-10, with an overall sample of 6331. Analyses of differences in overall levels of institutional trust between countries were undertaken using Chi square analyses. Multivariate binomial logistic regression analysis was undertaken to identify socio-demographic predictors of trust in each country. RESULTS: Religious institutions, banks and the judicial system had the highest overall trust across all countries (70%, 70% and 67% respectively), followed by newspapers and TV (59% and 58%) and then political leaders (43%). The range of levels of higher trust between countries differed from 43% for banks (range 49% in Australia to 92% in Thailand) to 59% for newspapers (28% in Australia to 87% in Japan). Across all countries, except for Australia, trust in political leaders had the lowest scores, particularly in Japan and South Korea (25% in both countries). In Thailand, people expressed the most trust in religious organisations (94%), banks (92%) and in their judicial/legal system (89%). In Hong Kong, people expressed the highest level of trust in their judicial/legal system (89%), followed by religious organisations (75%) and banks (77%). Australian respondents reported the least amount of trust in TV/media (24%) and press/newspapers (28%). South Korea put the least trust in their political leaders (25%), their legal system (43%) and religious organisations (45%). The key predictors of lower trust in institutions across all countries were males, people under 44 years and people unsatisfied with the health and standard of living. CONCLUSION: We interpreted our data using Fukuyama's theory of 'high/low trust' societies. The levels of institutional trust in each society did not conform to our hypothesis, with Thailand exhibiting the highest trust (predicted to be medium level), Hong Kong and Japan exhibiting medium trust (predicted to be low and high respectively) and Australia and South Korea exhibiting low trust (predicted to be high and medium respectively). Taiwan was the only country where the actual and predicted trust was the same, namely low trust. Given the fact that these predictors crossed national boundaries and institutional types, further research and policy should focus specifically on improving trust within these groups in order that they can be empowered to play a more central role in democratic vitality. PMID- 27701438 TI - Association of HLA-A and Non-Classical HLA Class I Alleles. AB - The HLA-A locus is surrounded by HLA class Ib genes: HLA-E, HLA-H, HLA-G and HLA F. HLA class Ib molecules are involved in immuno-modulation with a central role for HLA-G and HLA-E, an emerging role for HLA-F and a yet unknown function for HLA-H. Thus, the principal objective of this study was to describe the main allelic associations between HLA-A and HLA-H, -G, -F and -E. Therefore, HLA-A, E, -G, -H and -F coding polymorphisms, as well as HLA-G UnTranslated Region haplotypes (referred to as HLA-G UTRs), were explored in 191 voluntary blood donors. Allelic frequencies, Global Linkage Disequilibrium (GLD), Linkage Disequilibrium (LD) for specific pairs of alleles and two-loci haplotype frequencies were estimated. We showed that HLA-A, HLA-H, HLA-F, HLA-G and HLA-G UTRs were all in highly significant pairwise GLD, in contrast to HLA-E. Moreover, HLA-A displayed restricted associations with HLA-G UTR and HLA-H. We also confirmed several associations that were previously found to have a negative impact on transplantation outcome. In summary, our results suggest complex functional and clinical implications of the HLA-A genetic region. PMID- 27701440 TI - Inhibition of NET Release Fails to Reduce Adipose Tissue Inflammation in Mice. AB - Obesity-associated diseases such as Type 2 diabetes, liver disease and cardiovascular diseases are profoundly mediated by low-grade chronic inflammation of the adipose tissue. Recently, the importance of neutrophils and neutrophil derived myeloperoxidase and neutrophil elastase on the induction of insulin resistance has been established. Since neutrophil elastase and myeloperoxidase are critically involved in the release of neutrophil extracellular traps (NETs), we here hypothesized that NETs may be relevant to early adipose tissue inflammation. Thus, we tested the effect of the Peptidyl Arginine Deiminase 4 inhibitor Cl-amidine, a compound preventing histone citrullination and subsequent NET release, in a mouse model of adipose tissue inflammation. C57BL6 mice received a 60% high fat diet for 10 weeks and were treated with either Cl-amidine or vehicle. Flow cytometry of adipose tissue and liver, immunohistological analysis and glucose and insulin tolerance tests were performed to determine the effect of the treatment and diet. Although high fat diet feeding induced insulin resistance no significant effect was observed between the treatment groups. In addition no effect was found in leukocyte infiltration and activation in the adipose tissue and liver. Therefore we concluded that inhibition of neutrophil extracellular trap formation may have no clinical relevance for early obesity mediated pathogenesis of the adipose tissue and liver. PMID- 27701441 TI - Factors Associated with Visual Fatigue from Curved Monitor Use: A Prospective Study of Healthy Subjects. AB - PURPOSE: To investigate the factors associated with visual fatigue using monitors with various radii of curvature. METHODS: Twenty normal healthy adults (8 men, 12 women; mean age, 26.2 +/- 2.5 years) prospectively watched five types of monitors including flat, 4000R, 3000R, 2000R, and 1000R curved monitors for 30 min. An experienced examiner measured the ophthalmological factors including near point of accommodation (NPA), near point of convergence (NPC), refraction, parameters during pupil response at light and saccadic movement just before and after the visual tasks. The questionnaires about subjective ocular symptoms were also investigated just before and after the visual tasks. RESULTS: The NPA increased after the visual tasks with a flat monitor compared with the curved monitors, with the 1000R curved monitor showing the smallest change (p = 0.020). The NPC increased for every monitor after the visual tasks; the largest increase occurred with the flat monitor (p = 0.001). There was no difference in refractive error, pupil response, or saccadic movement in the comparison of before and after the visual tasks. Among the nine factors in the questionnaire, the score of "eye pain" was significantly higher for the flat monitor versus the 1000R curved monitor after the visual tasks (p = 0.034). CONCLUSIONS: We identified NPA, NPC, and eye pain as factors associated with visual fatigue. Also, the curvature of the monitor was related to the visual fatigue. PMID- 27701442 TI - A Longitudinal Operant Assessment of Cognitive and Behavioural Changes in the HdhQ111 Mouse Model of Huntington's Disease. AB - Huntington's disease (HD) is characterised by motor symptoms which are often preceded by cognitive and behavioural changes, that can significantly contribute to disease burden for people living with HD. Numerous knock-in mouse models of HD are currently available for scientific research. However, before their use, they must be behaviourally characterised to determine their suitability in recapitulating the symptoms of the human condition. Thus, we sought to longitudinally characterise the nature, severity and time course of cognitive and behavioural changes observed in HdhQ111 heterozygous knock-in mice.To determine changes in cognition and behaviour an extensive battery of operant tests including: fixed ratio, progressive ratio, the five choice serial reaction time task and the serial implicit learning task, were applied longitudinally to HdhQ111 and wild type mice. The operant test battery was conducted at 6, 12 and 18 months of age. Significant deficits were observed in HdhQ111 animals in comparison to wild type animals in all operant tests indicating altered cognition (attentional and executive function) and motivation. However, the cognitive and behavioural deficits observed were not shown to be progressive over time in the longitudinal testing paradigm that was utilised. The results therefore demonstrate that the HdhQ111 mouse model of HD reflects some features of the cognitive and behavioural changes shown in the human condition of HD. Although, the cognitive and behavioural deficits demonstrated were not shown to be progressive over time. PMID- 27701443 TI - Spatiotemporal Parameters of 100-m Sprint in Different Levels of Sprinters with Unilateral Transtibial Amputation. AB - The aim of this study was to investigate differences of the spatiotemporal parameters in a 100-m sprint among elite, sub-elite, and non-elite sprinters with a unilateral transtibial amputation. Using publicly available Internet broadcasts, we analyzed 125, 19, and 33 records from 30 elite, 12 sub-elite, and 22 non-elite sprinters, respectively. For each sprinter's run, the average velocity, step frequency, and step length were calculated using the number of steps in conjunction with the official race time. Average velocity was greatest in elite sprinters (8.71+/-0.32 m/s), followed by the sub-elite (8.09+/-0.06 m/s) and non-elite groups (7.72+/-0.27 m/s). Although there was a significant difference in average step frequency between the three groups, the effect size was small and the relative difference among the three groups was 3.1%. Statistical analysis also revealed that the average step length was longest in elite sprinters, followed by the sub-elite and non-elite groups. These results suggest that the differences in sprint performance between the three groups is mainly due to the average step length rather than step frequency. PMID- 27701444 TI - Protocadherin-1 Localization and Cell-Adhesion Function in Airway Epithelial Cells in Asthma. AB - BACKGROUND: The asthma gene PCDH1 encodes Protocadherin-1, a putative adhesion molecule of unknown function expressed in the airway epithelium. Here, we characterize the localization, differential expression, homotypic adhesion specificity and function of PCDH1 in airway epithelial cells in asthma. METHODS: We performed confocal fluorescence microscopy to determine subcellular localization of PCDH1 in 16HBE cells and primary bronchial epithelial cells (PBECs) grown at air-liquid interface. Next, to compare PCDH1 expression and localization in asthma and controls we performed qRT-PCR and fluorescence microscopy in PBECs and immunohistochemistry on airway wall biopsies. We examined homotypic adhesion specificity of HEK293T clones overexpressing fluorescently tagged-PCDH1 isoforms. Finally, to evaluate the role for PCDH1 in epithelial barrier formation and repair, we performed siRNA knockdown-studies and measured epithelial resistance. RESULTS: PCDH1 localized to the cell membrane at cell-cell contact sites, baso-lateral to adherens junctions, with increasing expression during epithelial differentiation. No differences in gene expression or localization of PCDH1 isoforms expressing the extracellular domain were observed in either PBECs or airway wall biopsies between asthma patients and controls. Overexpression of PCDH1 mediated homotypic interaction, whereas downregulation of PCDH1 reduced epithelial barrier formation, and impaired repair after wounding. CONCLUSIONS: In conclusion, PCDH1 is localized to the cell membrane of bronchial epithelial cells baso-lateral to the adherens junction. Expression of PCDH1 is not reduced nor delocalized in asthma even though PCDH1 contributes to homotypic adhesion, epithelial barrier formation and repair. PMID- 27701447 TI - Adaptive Path Selection for Link Loss Inference in Network Tomography Applications. AB - In this study, we address the problem of selecting the optimal end-to-end paths for link loss inference in order to improve the performance of network tomography applications, which infer the link loss rates from the path loss rates. Measuring the path loss rates using end-to-end probing packets may incur additional traffic overheads for networks, so it is important to select the minimum path set carefully while maximizing their performance. The usual approach is to select the maximum independent paths from the candidates simultaneously, while the other paths can be replaced by linear combinations of them. However, this approach ignores the fact that many paths always exist that do not lose any packets, and thus it is easy to determine that all of the links of these paths also have 0 loss rates. Not considering these good paths will inevitably lead to inefficiency and high probing costs. Thus, we propose an adaptive path selection method that selects paths sequentially based on the loss rates of previously selected paths. We also propose a theorem as well as a graph construction and decomposition approach to efficiently find the most valuable path during each round of selection. Our new method significantly outperforms the classical path selection method based on simulations in terms of the probing cost, number of accurate links determined, and the running speed. PMID- 27701445 TI - Determinants of the Transmission Variation of Hand, Foot and Mouth Disease in China. AB - Severe outbreaks of hand, foot and mouth disease (HFMD) have occurred in China for decades. Our understanding of the HFMD transmission process and its determinants is still limited. In this paper, factors that affect the local variation of HFMD transmission process were studied. Three classes of factors, including meteorological, demographic and public health intervention factors, were carefully selected and their effects on HFMD transmission were investigated with Pearson's correlation coefficient and multiple linear regression models. The determining factors for the variation of HFMD transmission were different for the southeastern and the northwestern regions of China. In the northwest, fadeouts occurred yearly, and the average age at infection and the fadeout were negatively correlated with the population density. In the southeast, HFMD transmission was governed by the combined effects of the birth rate, the relative humidity and the interaction of the Health System Performance and the log of the population density. When the Health System Performance was low, HFMD transmission increased with the population density, but when the Health System Performance was high, the better health performance counteracted the transmission increase due to the higher population density. PMID- 27701446 TI - An Evaluation of Passive and Active Approaches to Improve Tuberculosis Notifications in Afghanistan. AB - BACKGROUND: In Afghanistan, improving TB case detection remains challenging. In 2014, only half of the estimated incident TB cases were notified, and notifications have decreased since peaking in 2007. Active case finding has been increasingly considered to improve TB case notifications. While access to health services has improved in Afghanistan, it remains poor and many people seeking health services won't receive proper care. METHODS: From October 2011 through December 2012 we conducted three separate case finding strategies in six provinces of Afghanistan and measured impact on TB case notification. Systematically screening cough among attendees at 47 health facilities, active household contact investigation of smear-positive index TB patients, and active screening at 15 camps for internally displaced people were conducted. We collected both intervention yield and official quarterly notification data. Additional TB notifications were calculated by comparing numbers of cases notified during the intervention with those notified before the intervention, then adjusting for secular trends in notification. RESULTS: We screened 2,022,127 people for TB symptoms during the intervention, tested 59,838 with smear microscopy and detected 5,046 people with smear-positive TB. Most cases (81.7%, 4,125) were identified in health facilities while nearly 20% were found through active case finding. A 56% increase in smear-positive TB notifications was observed between the baseline and intervention periods among the 47 health facilities, where cases detected by all three strategies were notified. DISCUSSION: While most people with TB are likely to be identified through health facility screening, there are many people who remain without a proper diagnosis if outreach is not attempted. This is especially true in places like Afghanistan where access to general services is poor. Targeted active case finding can improve the number of people who are detected and treated for TB and can push towards the targets of the Stop TB Global Plan and End TB Strategy. PMID- 27701448 TI - Integrity of the Human Faecal Microbiota following Long-Term Sample Storage. AB - In studies of the human microbiome, faecal samples are frequently used as a non invasive proxy for the study of the intestinal microbiota. To obtain reliable insights, the need for bacterial DNA of high quality and integrity following appropriate faecal sample collection and preservation steps is paramount. In a study of dietary mineral balance in the context of type 2 diabetes (T2D), faecal samples were collected from healthy and T2D individuals throughout a 13-day residential trial. These samples were freeze-dried, then stored mostly at -20 degrees C from the trial date in 2000/2001 until the current research in 2014. Given the relative antiquity of these samples (~14 years), we sought to evaluate DNA quality and comparability to freshly collected human faecal samples. Following the extraction of bacterial DNA, gel electrophoresis indicated that our DNA extracts were more sheared than extracts made from freshly collected faecal samples, but still of sufficiently high molecular weight to support amplicon based studies. Likewise, spectrophotometric assessment of extracts revealed that they were of high quality and quantity. A subset of bacterial 16S rRNA gene amplicons were sequenced using Illumina MiSeq and compared against publicly available sequence data representing a similar cohort analysed by the American Gut Project (AGP). Notably, our bacterial community profiles were highly consistent with those from the AGP data. Our results suggest that when faecal specimens are stored appropriately, the microbial profiles are preserved and robust to extended storage periods. PMID- 27701449 TI - Bayesian Correlation Analysis for Sequence Count Data. AB - Evaluating the similarity of different measured variables is a fundamental task of statistics, and a key part of many bioinformatics algorithms. Here we propose a Bayesian scheme for estimating the correlation between different entities' measurements based on high-throughput sequencing data. These entities could be different genes or miRNAs whose expression is measured by RNA-seq, different transcription factors or histone marks whose expression is measured by ChIP-seq, or even combinations of different types of entities. Our Bayesian formulation accounts for both measured signal levels and uncertainty in those levels, due to varying sequencing depth in different experiments and to varying absolute levels of individual entities, both of which affect the precision of the measurements. In comparison with a traditional Pearson correlation analysis, we show that our Bayesian correlation analysis retains high correlations when measurement confidence is high, but suppresses correlations when measurement confidence is low-especially for entities with low signal levels. In addition, we consider the influence of priors on the Bayesian correlation estimate. Perhaps surprisingly, we show that naive, uniform priors on entities' signal levels can lead to highly biased correlation estimates, particularly when different experiments have widely varying sequencing depths. However, we propose two alternative priors that provably mitigate this problem. We also prove that, like traditional Pearson correlation, our Bayesian correlation calculation constitutes a kernel in the machine learning sense, and thus can be used as a similarity measure in any kernel-based machine learning algorithm. We demonstrate our approach on two RNA seq datasets and one miRNA-seq dataset. PMID- 27701450 TI - Multivariate Analysis of Anthropometric Traits Using Summary Statistics of Genome Wide Association Studies from GIANT Consortium. AB - Meta-analysis of single trait for multiple cohorts has been used for increasing statistical power in genome-wide association studies (GWASs). Although hundreds of variants have been identified by GWAS, these variants only explain a small fraction of phenotypic variation. Cross-phenotype association analysis (CPASSOC) can further improve statistical power by searching for variants that contribute to multiple traits, which is often relevant to pleiotropy. In this study, we performed CPASSOC analysis on the summary statistics from the Genetic Investigation of ANthropometric Traits (GIANT) consortium using a novel method recently developed by our group. Sex-specific meta-analysis data for height, body mass index (BMI), and waist-to-hip ratio adjusted for BMI (WHRadjBMI) from discovery phase of the GIANT consortium study were combined using CPASSOC for each trait as well as 3 traits together. The conventional meta-analysis results from the discovery phase data of GIANT consortium studies were used to compare with that from CPASSOC analysis. The CPASSOC analysis was able to identify 17 loci associated with anthropometric traits that were missed by conventional meta analysis. Among these loci, 16 have been reported in literature by including additional samples and 1 is novel. We also demonstrated that CPASSOC is able to detect pleiotropic effects when analyzing multiple traits. PMID- 27701451 TI - External Resistances Applied to MFC Affect Core Microbiome and Swine Manure Treatment Efficiencies. AB - Microbial fuel cells (MFCs) can be designed to combine water treatment with concomitant electricity production. Animal manure treatment has been poorly explored using MFCs, and its implementation at full-scale primarily relies on the bacterial distribution and activity within the treatment cell. This study reports the bacterial community changes at four positions within the anode of two almost identically operated MFCs fed swine manure. Changes in the microbiome structure are described according to the MFC fluid dynamics and the application of a maximum power point tracking system (MPPT) compared to a fixed resistance system (Ref-MFC). Both external resistance and cell hydrodynamics are thought to heavily influence MFC performance. The microbiome was characterised both quantitatively (qPCR) and qualitatively (454-pyrosequencing) by targeting bacterial 16S rRNA genes. The diversity of the microbial community in the MFC biofilm was reduced and differed from the influent swine manure. The adopted electric condition (MPPT vs fixed resistance) was more relevant than the fluid dynamics in shaping the MFC microbiome. MPPT control positively affected bacterial abundance and promoted the selection of putatively exoelectrogenic bacteria in the MFC core microbiome (Sedimentibacter sp. and gammaproteobacteria). These differences in the microbiome may be responsible for the two-fold increase in power production achieved by the MPPT-MFC compared to the Ref-MFC. PMID- 27701452 TI - Effects of Bariatric Surgery on Renal Function in Obese Patients: A Systematic Review and Meta Analysis. AB - BACKGROUND: Obesity is an independent risk factor of development and progression of chronic kidney disease (CKD). Data on the benefits of bariatric surgery in obese patients with impaired kidney function have been conflicting. OBJECTIVE: To explore whether there is improvement in glomerular filtration rate (GFR), proteinuria or albuminuria after bariatric surgery. METHODS: We comprehensively searched the databases of MEDLINE, Embase, web of science and Cochrane for randomized, controlled trials and observational studies that examined bariatric surgery in obese subjects with impaired kidney function. Outcomes included the pre- and post-bariatric surgery GFR, proteinuria and albuminuria. In obese patients with hyperfiltration, we draw conclusions from studies using measured GFR (inulin or iothalamate clearance) unadjusted for BSA only. Study quality was evaluated using the Newcastle-Ottawa Scale. RESULTS: 32 observational studies met our inclusion criteria, and 30 studies were included in the meta-analysis. No matter in dichotomous data or in dichotomous data, there were statistically significant reduction in hyperfiltration, albuminuria and proteinuria after bariatric surgery. LIMITATIONS: The main limitation of this meta-analysis is the lack of randomized controlled trials (RCTs). Another limitation is the lack of long-term follow-up. CONCLUSIONS: Bariatric surgery could prevent further decline in renal function by reducing proteinuria, albuminuria and improving glomerular hyperfiltration in obese patients with impaired renal function. However, whether bariatric surgery reverses CKD or delays ESRD progression is still in question, large, randomized prospective studies with a longer follow-up are needed. PMID- 27701453 TI - Plasma Pentosidine and Its Association with Mortality in Patients with Chronic Kidney Disease. AB - BACKGROUND: Circulating advanced glycated end-products (AGEs) including pentosidine accumulating in chronic kidney disease (CKD) patients due to retention and increased formation are thought to contribute to cardiovascular disease (CVD). Here we evaluated factors linked to increased plasma pentosidine and its association with mortality in patients with different stages of CKD and undergoing different treatments. METHODS: Plasma pentosidine, biomarkers of inflammation, oxidative stress and nutritional status were investigated in CKD 1 2 (n = 37), CKD 3-4 (n = 54), CKD 5 non-dialyzed (CKD5-ND; n = 386), peritoneal dialysis (PD; n = 74) and hemodialysis (HD; n = 195) patients. Factors predicting plasma pentosidine were analysed by multivariate regression analysis and mortality risk was assessed by GENMOD procedure. RESULTS: Plasma pentosidine levels, which were higher in CKD5-ND, PD and HD groups than in CKD 1-2 group, were significantly lower in PD than in HD patients, and not different between PD patients and CKD5-ND patients. Pentosidine associated inversely with glomerular filtration rate (GFR), and additionally in PD with 8-hydroxy-2'-deoxyguanosine (8 OHdG), and interleukin 6 (IL-6); in HD with age, IL-6 and body mass index (BMI); in CKD5-ND with age, 8-OHdG, IL-6, high-sensitive C-reactive protein (hsCRP), and soluble vascular cell adhesion protein-1 (sVCAM-1); in CKD 3-4 with 8-OHdG and sVCAM-1; and in CKD 1-2 with age and sVCAM-1. In multivariate analysis, age (one standard deviation, 1-SD higher), malnutrition (subjective global assessment, SGA), oxidative stress (8-OHdG, 1-SD higher), and belonging to CKD5-ND, HD and PD cohorts associated with 1-SD higher pentosidine. In GENMOD, 1-SD higher pentosidine independently predicted all-cause mortality (relative risk, RR = 1.04; 95% confidence interval, CI, 1.01-1.08, p = 0.01) and CVD mortality (RR = 1.03; 95% CI, 1.01-1.06, p = 0.03) after adjusting for all confounders. CONCLUSIONS: Plasma pentosidine is markedly elevated in CKD and associates with low GFR, oxidative stress and inflammation, and is an independent predictor of mortality in CKD patients. PMID- 27701454 TI - Microbiota of the Small Intestine Is Selectively Engulfed by Phagocytes of the Lamina Propria and Peyer's Patches. AB - Phagocytes such as dendritic cells and macrophages, which are distributed in the small intestinal mucosa, play a crucial role in maintaining mucosal homeostasis by sampling the luminal gut microbiota. However, there is limited information regarding microbial uptake in a steady state. We investigated the composition of murine gut microbiota that is engulfed by phagocytes of specific subsets in the small intestinal lamina propria (SILP) and Peyer's patches (PP). Analysis of bacterial 16S rRNA gene amplicon sequences revealed that: 1) all the phagocyte subsets in the SILP primarily engulfed Lactobacillus (the most abundant microbe in the small intestine), whereas CD11bhi and CD11bhiCD11chi cell subsets in PP mostly engulfed segmented filamentous bacteria (indigenous bacteria in rodents that are reported to adhere to intestinal epithelial cells); and 2) among the Lactobacillus species engulfed by the SILP cell subsets, L. murinus was engulfed more frequently than L. taiwanensis, although both these Lactobacillus species were abundant in the small intestine under physiological conditions. These results suggest that small intestinal microbiota is selectively engulfed by phagocytes that localize in the adjacent intestinal mucosa in a steady state. These observations may provide insight into the crucial role of phagocytes in immune surveillance of the small intestinal mucosa. PMID- 27701456 TI - Robust and Efficient Frequency Estimator for Undersampled Waveforms Based on Frequency Offset Recognition. AB - This paper proposes an efficient frequency estimator based on Chinese Remainder Theorem for undersampled waveforms. Due to the emphasis on frequency offset recognition (i.e., frequency shift and compensation) of small-point DFT remainders, compared to estimators using large-point DFT remainders, it can achieve higher noise robustness in low signal-to-noise ratio (SNR) cases and higher accuracy in high SNR cases. Numerical results show that, by incorporating a remainder screening method and the Tsui spectrum corrector, the proposed estimator not only lowers the SNR threshold of detection, but also provides a higher accuracy than the large-point DFT estimator when the DFT size decreases to 1/90 of the latter case.

AB - INTRODUCTION: The growth factor HBEGF is upregulated post-transcriptionally in the low O2 environment of the human placenta during the first 10 weeks of pregnancy. We have examined the possible roles of HBEGF turnover and micro-RNA (miRNA) in its regulation by O2 in human first trimester trophoblast. METHODS: HTR-8/SVneo trophoblast cells were cultured at 2% or 20% O2. The cells were transfected with a dual luciferase reporter construct (psiCHECK-2) containing no insert (control), the HBEGF 3' untranslated region (3'UTR), or sub-regions of the 3'UTR, as well as with siRNA for DGCR8. RNA was extracted from trophoblast cells cultured at 2% O2 for 0-4 h for next-generation sequencing. HBEGF was quantified by ELISA. HBEGF, DGCR8, and beta-actin were examined by western blotting. RESULTS: Protein turnover studies, using 10 MUg/ml cyclohexamide, 1 MUg/ml lactocystin, or 100 MUg/ml MG132, demonstrated faster HBEGF degradation at 20% O2 than 2% O2, mediated by the proteasome. However, proteasome inhibition failed to initiate HBEGF accumulation at 20% O2. Reporter assays, comparing to empty vector, demonstrated that the intact HBEGF 3' UTR inhibited expression (0.26), while fragments containing only its flanking regions increased reporter activity (3.15; 3.43). No differential expression of miRNAs was found in trophoblast cells cultured at 2% and 20% O2. Nevertheless, HBEGF upregulation at 2% O2 was blocked when the miRNA-processing protein DGCR8 was silenced, suggesting a role for miRNA. CONCLUSION: Our findings suggest involvement of flanking regions of the 3'UTR in activating HBEGF protein synthesis in response to 2% O2, possibly through a miRNA-mediated mechanism.

AB - We consider a dynamical model of distress propagation on complex networks, which we apply to the study of financial contagion in networks of banks connected to each other by direct exposures. The model that we consider is an extension of the DebtRank algorithm, recently introduced in the literature. The mechanics of distress propagation is very simple: When a bank suffers a loss, distress propagates to its creditors, who in turn suffer losses, and so on. The original DebtRank assumes that losses are propagated linearly between connected banks. Here we relax this assumption and introduce a one-parameter family of non-linear propagation functions. As a case study, we apply this algorithm to a data-set of 183 European banks, and we study how the stability of the system depends on the non-linearity parameter under different stress-test scenarios. We find that the system is characterized by a transition between a regime where small shocks can be amplified and a regime where shocks do not propagate, and that the overall stability of the system increases between 2008 and 2013. PMID- 27701458 TI - A Precise Annotation of Phase-Amplitude Coupling Intensity. AB - Neuronal information can be coded in different temporal and spatial scales. Cross frequency coupling of neuronal oscillations, especially phase-amplitude coupling (PAC), plays a critical functional role in neuronal communication and large scale neuronal encoding. Several approaches have been developed to assess PAC intensity. It is generally agreed that the PAC intensity relates to the uneven distribution of the fast oscillation amplitude conditioned on the slow oscillation phase. However, it is still not clear what the PAC intensity exactly means. In the present study, it was found that there were three types of interferential signals taking part in PAC phenomenon. Based on the classification of interferential signals, the conception of PAC intensity is theoretically annotated as the proportion of slow or fast oscillation that is involved in a related PAC phenomenon. In order to make sure that the annotation is proper to some content, simulation data are constructed and then analyzed by three PAC approaches. These approaches are the mean vector length (MVL), the modulation index (MI), and a new permutation mutual information (PMI) method in which the permutation entropy and the information theory are applied. Results show positive correlations between PAC values derived from all three methods and the suggested intensity. Finally, the amplitude distributions, i.e. the phase-amplitude plots, obtained from different PAC intensities show that the annotation proposed in the study is in line with the previous understandings.

AB - The pentaspan membrane glycoprotein prominin-1 (CD133) is widely used in medicine as a cell surface marker of stem and cancer stem cells. It has opened new avenues in stem cell-based regenerative therapy and oncology. This molecule is largely used with human samples or the mouse model, and consequently most biological tools including antibodies are directed against human and murine prominin-1. Although the general structure of prominin-1 including its membrane topology is conserved throughout the animal kingdom, its primary sequence is poorly conserved. Thus, it is unclear if anti-human and -mouse prominin-1 antibodies cross-react with their orthologs in other species, especially dog. Answering this issue is imperative in light of the growing number of studies using canine prominin-1 as an antigenic marker. Here, we address this issue by cloning the canine prominin-1 and use its overexpression as a green fluorescent protein fusion protein in Madin-Darby canine kidney cells to determine its immunoreactivity with antibodies against human or mouse prominin-1. We used immunocytochemistry, flow cytometry and immunoblotting techniques and surprisingly found no cross-species immunoreactivity. These results raise some caution in data interpretation when anti-prominin-1 antibodies are used in interspecies studies. PMID- 27701460 TI - The Replicative Consequences of Papillomavirus E2 Protein Binding to the Origin Replication Factor ORC2. AB - The origin recognition complex (ORC) coordinates a series of events that lead to initiation of DNA strand duplication. As a nuclear double stranded DNA plasmid, the papillomavirus (PV) genome resembles a mini-chromosome in infected cells. To initiate its replication, the viral E2 protein binds to and recruits the E1 DNA helicase at the viral origin. PV genome replication program exhibits three stages: initial amplification from a single genome upon infection to a few copies per cell, a cell cycle linked maintenance phase, and a differentiation dependent late stage where the genome is amplified to thousands of copies. Involvement of ORC or other pre-replication complex (pre-RC) factors has not been described. We report that human PV (HPV) and bovine PV (BPV-1) E2 proteins bind to ORC2, however, ORC2 was not detected at the viral origin. Depletion of ORC2 enhanced PV replication in a transient replication model and in keratinocytes stably maintaining viral episomes, while there was no effect on copy number in a cell line with integrated HPV genomes. Consistent with this, occupancy of E1 and E2 at the viral origin increased following ORC2 silencing. These data imply that ORC2 is not necessary for activation of the PV origin by E1 and E2 but instead suppresses E2 replicative function. Furthermore, we observed that over-expression of HPV E2 decreased ORC2 occupation at two known mammalian origins of replication, suggesting that E2 restricts pre-ORC assembly that could otherwise compete for host replication complexes necessary for viral genome amplification. We infer that the ORC2 complex with E2 restricts viral replication in the maintenance phase of the viral replication program and that elevated levels of E2 that occur during the differentiation dependent amplification stage subvert ORC loading and hence DNA synthesis at cellular origins. PMID- 27701461 TI - MUC18 Regulates Lung Rhinovirus Infection and Inflammation. AB - BACKGROUND: MUC18 is upregulated in the lungs of asthma and COPD patients. It has been shown to have pro-inflammatory functions in cultured human airway epithelial cells during viral infections and in mice during lung bacterial infections. However, the in vivo role of MUC18 in the context of viral infections remains poorly understood. The goal of this study is to define the in vivo function of MUC18 during respiratory rhinovirus infection. METHODS: Muc18 wild-type (WT) and knockout (KO) mice were infected with human rhinovirus 1B (HRV-1B) and sacrificed after 1 day to determine the inflammatory and antiviral responses. To examine the direct effects of Muc18 on viral infection, tracheal epithelial cells isolated from WT and KO mice were grown under air-liquid interface and infected with HRV 1B. Finally, siRNA mediated knockdown of MUC18 was performed in human airway epithelial cells (AECs) to define the impact of MUC18 on human airway response to HRV-1B. RESULTS: Both viral load and neutrophilic inflammation were significantly decreased in Muc18 KO mice compared to WT mice. In the in vitro setting, viral load was significantly lower and antiviral gene expression was higher in airway epithelial cells of Muc18 KO mice than the WT mice. Furthermore, in MUC18 knockdown human AECs, viral load was decreased and antiviral gene expression was increased compared to controls. CONCLUSIONS: Our study is the first to demonstrate MUC18's pro-inflammatory and pro-viral function in an in vivo mouse model of rhinovirus infection. PMID- 27701462 TI - Accuracy of a Real-Time, Computerized, Binocular, Three-Dimensional Trajectory Tracking Device for Recording Functional Mandibular Movements. AB - OBJECTIVE: Developments in digital technology have permitted researchers to study mandibular movements. Here, the accuracy of a real-time, computerized, binocular, three-dimensional (3D) trajectory-tracking device for recording functional mandibular movements was evaluated. METHODS: An occlusal splint without the occlusal region was created based on a plaster cast of the lower dentition. The splint was rigidly connected with a target on its labial side and seated on the cast. The cast was then rigidly attached to the stage of a high-precision triaxial electronic translator, which was used to move the target-cast-stage complex. Half-circular movements (5.00-mm radius) in three planes (XOY, XOZ, YOZ) and linear movements along the x-axis were performed at 5.00 mm/s. All trajectory points were recorded with the binocular 3D trajectory-tracking device and fitted to arcs or lines, respectively, with the Imageware software. To analyze the accuracy of the trajectory-tracking device, the mean distances between the trajectory points and the fitted arcs or lines were measured, and the mean differences between the lengths of the fitted arcs' radii and a set value (5.00 mm) were then calculated. A one-way analysis of variance was used to evaluate the spatial consistency of the recording accuracy in three different planes. RESULTS: The mean distances between the trajectory points and fitted arcs or lines were 0.076 +/- 0.033 mm or 0.089 +/- 0.014 mm. The mean difference between the lengths of the fitted arcs' radii and the set value (5.00 mm) was 0.025 +/- 0.071 mm. A one-way ANOVA showed that the recording errors in three different planes were not statistically significant. CONCLUSION: These results suggest that the device can record certain movements at 5.00 mm/s, which is similar to the speed of functional mandibular movements. In addition, the recordings had an error of <0.1 mm and good spatial consistency. Thus, the device meets some of the requirements necessary for recording human mandibular movements. PMID- 27701463 TI - Low-Grade Inflammation Is Associated with Susceptibility to Infection in Healthy Men: Results from the Danish Blood Donor Study (DBDS). AB - INTRODUCTION: The aim of this study was to examine whether low-grade inflammation (LGI) is associated with a subsequently increased risk of infection. METHODS: We included 15,754 healthy participants from the Danish Blood Donor Study, who completed a questionnaire on health-related items. LGI was defined as a C reactive protein level between 3 and 10 mg/L. Infections were identified by ICD 10 codes in the Danish National Patient Register and ATC-codes in the Danish Prescription Register. Multivariable Cox proportional hazard analysis was used as the statistical model. RESULTS: During 53,302 person-years of observation, 571 participants were hospitalized for infection. Similarly, during 26,125 person years of observation, 7,276 participants filled a prescription of antimicrobials. LGI was associated with increased risk of hospital-based treatment for infection only among men (hazard ratio = 1.60, 95% confidence interval (CI): 1.10-2.34) and specifically infections were abscesses and infections of the skin and subcutaneous tissue. Similarly, LGI was associated with the overall use of antimicrobials among men, and particularly with phenoxymethylpenicillin and broad spectrum antimicrobials for treatment of urinary tract infections. The difference between men and women was not statistically significant. CONCLUSIONS: In a large cohort of healthy individuals, LGI was associated with an increased risk of infection among healthy male blood donors. PMID- 27701464 TI - The Positron Emission Tomography Tracer 3'-Deoxy-3'-[18F]Fluorothymidine ([18F]FLT) Is Not Suitable to Detect Tissue Proliferation Induced by Systemic Yersinia enterocolitica Infection in Mice. AB - Most frequently, gram-negative bacterial infections in humans are caused by Enterobacteriaceae and remain a major challenge in medical diagnostics. We non invasively imaged moderate and severe systemic Yersinia enterocolitica infections in mice using the positron emission tomography (PET) tracer 3'-deoxy-3' [18F]fluorothymidine ([18F]FLT), which is a marker of proliferation, and compared the in vivo results to the ex vivo biodistributions, bacterial loads, and histologies of the corresponding organs. Y. enterocolitica infection is detectable with histology using H&E staining and immunohistochemistry for Ki 67. [18F]FLT revealed only background uptake in the spleen, which is the main manifestation site of systemic Y. enterocolitica-infected mice. The uptake was independent of the infection dose. Antibody-based thymidine kinase 1 (Tk-1) staining confirmed the negative [18F]FLT-PET data. Histological alterations of spleen tissue, observed via Ki 67-antibody-based staining, can not be detected by [18F]FLT-PET in this model. Thus, the proliferation marker [18F]FLT is not a suitable tracer for the diagnosis of systemic Y. enterocolitica infection in the C57BL/6 animal model of yersiniosis. PMID- 27701465 TI - MicroRNA-20b (miR-20b) Promotes the Proliferation, Migration, Invasion, and Tumorigenicity in Esophageal Cancer Cells via the Regulation of Phosphatase and Tensin Homologue Expression. AB - Increasing evidence has indicated that many microRNAs participate in the development and progression of esophageal cancer and gene expression regulation. MicroRNA-20b (miR-20b) has been reported to be aberrantly expressed in various cancers, but its exact role in esophageal cancer cells remains unclear so far. Therefore, we detected the levels of miR-20b in esophageal tumor tissues and their adjacent normal tissues, and various esophageal cancer cell lines by qRT PCR. We also explored the effects of miR-20b on cell proliferation, migration, invasion and tumorigenicity of esophageal carcinoma cells through transfection with miR-20b mimics or inhibitor to upregulate or downregulate miR-20b expression in the esophageal cancer cells Eca-109 and KYSE-150, respectively. Additionally, the 3'-untranslated region (3'-UTR) of phosphatase and tensin homologue (PTEN) binding with miR-20b was analyzed by dual-luciferase reporter assays. The results indicated that miR-20b expression level in esophageal tumor tissues was significantly increased compared with their neighboring normal tissues, but its expression was inverse with PTEN protein expression. Luciferase assays confirmed that the 3'-UTR of PTEN was a target of miR-20b in esophageal cancer cells. MiR 20b upregulation promoted cell proliferation, migration, invasiveness, and tumor growth, and decreased apoptosis, and reduced PTEN protein level but not mRNA expression in Eca-109 cells. Conversely, downregulation of miR-20b suppressed these processes in KYSE-150 cells, and enhanced PTEN protein expression. These data indicate that miR-20b plays important roles in tumorigenesis of esophageal cancer possibly via regulation of PTEN expression, and it may be a potential therapeutic target for esophageal cancer treatment. PMID- 27701466 TI - Use of the 'Accountability for Reasonableness' Approach to Improve Fairness in Accessing Dialysis in a Middle-Income Country. AB - Universal access to renal replacement therapy is beyond the economic capability of most low and middle-income countries due to large patient numbers and the high recurrent cost of treating end stage kidney disease. In countries where limited access is available, no systems exist that allow for optimal use of the scarce dialysis facilities. We previously reported that using national guidelines to select patients for renal replacement therapy resulted in biased allocation. We reengineered selection guidelines using the 'Accountability for Reasonableness' (procedural fairness) framework in collaboration with relevant stakeholders, applying these in a novel way to categorize and prioritize patients in a unique hierarchical fashion. The guidelines were primarily premised on patients being transplantable. We examined whether the revised guidelines enhanced fairness of dialysis resource allocation. This is a descriptive study of 1101 end stage kidney failure patients presenting to a tertiary renal unit in a middle-income country, evaluated for dialysis treatment over a seven-year period. The Assessment Committee used the accountability for reasonableness-based guidelines to allocate patients to one of three assessment groups. Category 1 patients were guaranteed renal replacement therapy, Category 3 patients were palliated, and Category 2 were offered treatment if resources allowed. Only 25.2% of all end stage kidney disease patients assessed were accepted for renal replacement treatment. The majority of patients (48%) were allocated to Category 2. Of 134 Category 1 patients, 98% were accepted for treatment while 438 (99.5%) Category 3 patients were excluded. Compared with those palliated, patients accepted for dialysis treatment were almost 10 years younger, employed, married with children and not diabetic. Compared with our previous selection process our current method of priority setting based on procedural fairness arguably resulted in more equitable allocation of treatment but, more importantly, it is a model that is morally, legally and ethically more defensible. PMID- 27701467 TI - Germline Variants of Prostate Cancer in Japanese Families. AB - Prostate cancer (PC) is the second most common cancer in men. Family history is the major risk factor for PC. Only two susceptibility genes were identified in PC, BRCA2 and HOXB13. A comprehensive search of germline variants for patients with PC has not been reported in Japanese families. In this study, we conducted exome sequencing followed by Sanger sequencing to explore responsible germline variants in 140 Japanese patients with PC from 66 families. In addition to known susceptibility genes, BRCA2 and HOXB13, we identified TRRAP variants in a mutually exclusive manner in seven large PC families (three or four patients per family). We also found shared variants of BRCA2, HOXB13, and TRRAP from 59 additional small PC families (two patients per family). We identified two deleterious HOXB13 variants (F127C and G132E). Further exploration of the shared variants in rest of the families revealed deleterious variants of the so-called cancer genes (ATP1A1, BRIP1, FANCA, FGFR3, FLT3, HOXD11, MUTYH, PDGFRA, SMARCA4, and TCF3). The germline variant profile provides a new insight to clarify the genetic etiology and heterogeneity of PC among Japanese men. PMID- 27701468 TI - Determinants of Left Atrial Volume in Patients with Atrial Fibrillation. AB - INTRODUCTION: Left atrial (LA) enlargement is an important risk factor for incident stroke and a key determinant for the success of rhythm control strategies in patients with atrial fibrillation (AF). However, factors associated with LA volume in AF patients remain poorly understood. METHODS: Patients with paroxysmal or persistent AF were enrolled in this study. Real time 3-D echocardiography was performed in all participants and analyzed offline in a standardized manner. We performed stepwise backward linear regression analyses using a broad set of clinical parameters to determine independent correlates for 3-D LA volume. RESULTS: We included 210 patients (70.9% male, mean age 61+/ 11years). Paroxysmal and persistent AF were present in 95 (45%) and 115 (55%) patients, respectively. Overall, 115 (55%) had hypertension, 11 (5%) had diabetes, and 18 (9%) had ischemic heart disease. Mean indexed LA volume was 36+/ 12ml/m2. In multivariable models, significant associations were found for female sex (beta coefficient -10.51 (95% confidence interval (CI) -17.85;-3.16), p = 0.0053), undergoing cardioversion (beta 11.95 (CI 5.15; 18.74), p = 0.0006), diabetes (beta 14.23 (CI 2.36; 26.10), p = 0.019), body surface area (BSA) (beta 34.21 (CI 19.30; 49.12), p<0.0001), glomerular filtration rate (beta -0.21 (CI 0.36; -0.06), p = 0.0064) and plasma levels of NT-pro brain natriuretic peptide (NT-proBNP) (beta 6.79 (CI 4.05; 9.52), p<0.0001), but not age (p = 0.59) or hypertension (p = 0.42). Our final model explained 52% of the LA volume variability. CONCLUSIONS: In patients with AF, the most important correlates with LA volume are sex, BSA, diabetes, renal function and NT-proBNP, but not age or hypertension. These results may help to refine rhythm control strategies in AF patients. PMID- 27701469 TI - Impact of TNF-alpha (rs1800629) and IL-6 (rs1800795) Polymorphisms on Cognitive Impairment in Asian Breast Cancer Patients. AB - OBJECTIVE: Expression of pro-inflammatory cytokines is influenced by single nucleotide polymorphisms (SNPs) in the promoter regions of the pro-inflammatory cytokine genes, and cytokines are associated with the occurrence of post chemotherapy cognitive impairment. Hence, the aim of this study was to evaluate the associations between two common pro-inflammatory cytokine gene polymorphisms namely, IL6-174 (rs1800795 G>C) and TNF-308 (rs1800629 G>A), and chemotherapy associated cognitive impairment (CACI) among Asian early-stage breast cancer patients. In addition, the differential effect of these SNPs on plasma IL-6 and TNF-alpha levels, and the associations of plasma IL-6 and TNF-alpha levels with CACI were also assessed. METHODS: Asian early-stage breast cancer patients (Stage I to III) receiving chemotherapy were prospectively recruited from two cancer centers in Singapore. Patients' cognitive function was longitudinally assessed using the validated FACT-Cog (ver. 3) and an objective computerized battery, HeadminderTM at three-time points. Plasma IL-6 and TNF-alpha levels were analyzed using the multiplex immunoassay, and genotyping was performed using Sanger sequencing. Regression analyses and generalized estimating equation were utilized for statistical analysis. RESULTS: A total of 125 patients were included (mean age: 50.3; Chinese: 80.8%; post-menopausal: 48.0%; 68.0% received anthracycline based chemotherapy). 36.8% patients experienced self-perceived cognitive impairment, detected in memory (32.8%) and attention (34.2%) domains. Patients with higher levels of anxiety (p<0.001) and insomnia (p = 0.003) also reported more self-perceived cognitive impairment. Higher plasma concentrations of IL-6 were associated with greater severity of self-perceived cognitive impairment (p = 0.001). Polymorphisms of cytokine genes were not associated with expression of plasma cytokines. CONCLUSION: Present findings further contribute to the growing evidence that supports the role of the pro-inflammatory cytokine IL-6 in the occurrence of cognitive impairment post-chemotherapy. However, genetic polymorphism of these cytokines did not play a major role to the cytokine fluctuations as well as cognitive impairment in this cohort. With an increasing evidence to support the cytokine hypothesis, future studies should investigate the role of anti-inflammatory agents in mitigating the cognitive impairment associated with chemotherapy. PMID- 27701470 TI - Neuronal Splicing Regulator RBFOX3 (NeuN) Regulates Adult Hippocampal Neurogenesis and Synaptogenesis. AB - Dysfunction of RBFOX3 has been identified in neurodevelopmental disorders such as autism spectrum disorder, cognitive impairments and epilepsy and a causal relationship with these diseases has been previously demonstrated with Rbfox3 homozygous knockout mice. Despite the importance of RBFOX3 during neurodevelopment, the function of RBFOX3 regarding neurogenesis and synaptogenesis remains unclear. To address this critical question, we profiled the developmental expression pattern of Rbfox3 in the brain of wild-type mice and analyzed brain volume, disease-relevant behaviors, neurogenesis, synaptic plasticity, and synaptogenesis in Rbfox3 homozygous knockout mice and their corresponding wild-type counterparts. Here we report that expression of Rbfox3 differs developmentally for distinct brain regions. Moreover, Rbfox3 homozygous knockout mice exhibited cold hyperalgesia and impaired cognitive abilities. Focusing on hippocampal phenotypes, we found Rbfox3 homozygous knockout mice displayed deficits in neurogenesis, which was correlated with cognitive impairments. Furthermore, RBFOX3 regulates the exons of genes with synapse related function. Synaptic plasticity and density, which are related to cognitive behaviors, were altered in the hippocampal dentate gyrus of Rbfox3 homozygous knockout mice; synaptic plasticity decreased and the density of synapses increased. Taken together, our results demonstrate the important role of RBFOX3 during neural development and maturation. In addition, abnormalities in synaptic structure and function occur in Rbfox3 homozygous knockout mice. Our findings may offer mechanistic explanations for human brain diseases associated with dysfunctional RBFOX3.

AB - PURPOSE: To explore the readability and content integrity of informed consent forms (ICFs) used in China and to compare the quality of Chinese local ICFs with that of international ICFs. METHODS: The length, readability and content of 155 consent documents from phase II-IV drug clinical trials from the Third Xiangya Hospital Ethics Committee from November 2009 to January 2015 were evaluated. Reading difficulty was tested using a readability formula adapted for the Chinese language. An ICF checklist containing 27 required elements was successfully constructed to evaluate content integrity. The description of alternatives to participation was assessed. The quality of ICFs from different sponsorships were also compared. RESULTS: Among the 155 evaluable trials, the ICFs had a median length of 5286 words, corresponding to 7 pages. The median readability score was 4.31 (4.02-4.41), with 63.9% at the 2nd level and 36.1% at the 3rd level. Five of the 27 elements were frequently neglected. The average score for the description of alternatives to participation was 1.06, and 27.7% of the ICFs did not mention any alternatives. Compared with Chinese local ICFs, international ICFs were longer, more readable and contained more of the required elements (P < 0.05). CONCLUSION: The ICFs used in China were difficult to read for most participants. These forms had poor description of alternatives to participation, and failed to provide a high degree of information disclosure, including an explanation of informed consent, follow-up processing of the data/sample, inclusion/exclusion criteria, double blinding, and unpredictable risks. International ICFs had better readability and content integrity than Chinese local ICFs. More efforts should thus be made to improve the quality of consent documents in China. PMID- 27701473 TI - Flagellin FliC Phosphorylation Affects Type 2 Protease Secretion and Biofilm Dispersal in Pseudomonas aeruginosa PAO1. AB - Protein phosphorylation has a major role in controlling the life-cycle and infection stages of bacteria. Proteome-wide occurrence of S/T/Y phosphorylation has been reported for many prokaryotic systems. Previously, we reported the phosphoproteome of Pseudomonas aeruginosa and Pseudomonas putida. In this study, we show the role of S/T phosphorylation of one motility protein, FliC, in regulating multiple surface-associated phenomena of P. aeruginosa PAO1. This is the first report of occurrence of phosphorylation in the flagellar protein, flagellin FliC in its highly conserved N-terminal NDO domain across several Gram negative bacteria. This phosphorylation is likely a well-regulated phenomenon as it is growth phase dependent in planktonic cells. The absence of phosphorylation in the conserved T27 and S28 residues of FliC, interestingly, did not affect swimming motility, but affected the secretome of type 2 secretion system (T2SS) and biofilm formation of PAO1. FliC phosphomutants had increased levels and activities of type 2 secretome proteins. The secretion efficiency of T2SS machinery is associated with flagellin phosphorylation. FliC phosphomutants also formed reduced biofilms at 24 h under static conditions and had delayed biofilm dispersal under dynamic flow conditions, respectively. The levels of type 2 secretome and biofilm formation under static conditions had an inverse correlation. Hence, increase in type 2 secretome levels was accompanied by reduced biofilm formation in the FliC phosphomutants. As T2SS is involved in nutrient acquisition and biofilm dispersal during survival and spread of P. aeruginosa, we propose that FliC phosphorylation has a role in ecological adaptation of this opportunistic environmental pathogen. Altogether, we found a system of phosphorylation that affects key surface related processes such as proteases secretion by T2SS, biofilm formation and dispersal. PMID- 27701474 TI - Staphylococcus aureus Tissue Infection During Sepsis Is Supported by Differential Use of Bacterial or Host-Derived Lipoic Acid. AB - To thrive in diverse environments, bacteria must shift their metabolic output in response to nutrient bioavailability. In many bacterial species, such changes in metabolic flux depend upon lipoic acid, a cofactor required for the activity of enzyme complexes involved in glycolysis, the citric acid cycle, glycine catabolism, and branched chain fatty acid biosynthesis. The requirement of lipoic acid for metabolic enzyme activity necessitates that bacteria synthesize the cofactor and/or scavenge it from environmental sources. Although use of lipoic acid is a conserved phenomenon, the mechanisms behind its biosynthesis and salvage can differ considerably between bacterial species. Furthermore, low levels of circulating free lipoic acid in mammals underscore the importance of lipoic acid acquisition for pathogenic microbes during infection. In this study, we used a genetic approach to characterize the mechanisms of lipoic acid biosynthesis and salvage in the bacterial pathogen Staphylococcus aureus and evaluated the requirements for both pathways during murine sepsis. We determined that S. aureus lipoic acid biosynthesis and salvage genes exist in an arrangement that directly links redox stress response and acetate biosynthesis genes. In addition, we found that lipoic acid salvage is dictated by two ligases that facilitate growth and lipoylation in distinct environmental conditions in vitro, but that are fully compensatory for survival in vivo. Upon infection of mice, we found that de novo biosynthesis or salvage promotes S. aureus survival in a manner that depends upon the infectious site. In addition, when both lipoic acid biosynthesis and salvage are blocked S. aureus is rendered avirulent, implying an inability to induce lipoic acid-independent metabolic programs to promote survival. Together, our results define the major pathways of lipoic acid biosynthesis and salvage in S. aureus and support the notion that bacterial nutrient acquisition schemes are instrumental in dictating pathogen proclivity for an infectious niche. PMID- 27701480 TI - Factors associated with early mortality in haemodialysis patients undergoing coronary artery bypass surgery. AB - INTRODUCTION: Coronary artery bypass grafting (CABG) results in higher morbidity and mortality rates in end-stage renal disease (ESRD) patient populations than in patients with normal renal function. This study aimed to identify the early results of CABG performed on ESRD patients, and the factors that affected the mortality rates of those patients. METHODS: A retrospective evaluation of our hospital database revealed 84 haemodialysis-receiving patients who underwent CABG during the years 2006 to 2012. Mortality was observed in 21 patients (group 1), and this group was compared with the remaining patients (group 2) for peri operative parameters such as age, EuroSCORE, functional capacity, myocardial infarction, use of inotropes and completeness of revascularisation. RESULTS: The study included 60 male (71.4%) and 24 female patients (28.6%); the participants' mean age was 59.50 +/- 9.93 years. The pre-operative additive EuroSCORE was 7.96 +/- 2.88 (range: 2-18). Pre-operative functional capacity was impaired in 35.7% of the patients [New York Heart Association (NYHA) classes III-IV]. Mean age and preoperative EuroSCORE values of group 1 were significantly higher than those of group 2. Impaired functional capacity (NHYA classes III-IV) was also associated with mortality (OR: 3.333; 95% CI: 1.199-9.268). Fifty-four patients (64.3%) underwent on-pump CABG procedures, and 30 (35.7%) underwent off-pump CABG procedures. The study found no statistically significant difference in mortality rates between these two techniques. Mortality occurred in 12 patients (22.2%) in the on-pump group and in nine (30%) in the off-pump group. Complete revascularisation was performed on 46 patients (85.2%) in the on-pump group and seven (23.3%) in the off-pump group (p < 0.001). CONCLUSION: Advanced age, impaired NYHA functional capacity and pre-operative hypertension were determinative for early-term surgical mortality. An on-pump surgical technique is recommended to ensure completeness of revascularisation. PMID- 27701481 TI - The effects of the metabolic syndrome on coronary artery bypass grafting surgery. AB - BACKGROUND: The metabolic syndrome (MS) is a clustering of factors that are associated with increased cardiovascular risk. A low-grade inflammatory process acts as the underlying pathophysiology, which suggests that the MS may have a detrimental effect on coronary interventions, including coronary artery bypass grafting (CABG) surgery performed with cardiopulmonary bypass (CPB). We aimed to evaluate the effect of the MS on morbidity and mortality rates in the early postoperative period in patients undergoing CABG. METHODS: We prospectively included 152 patients (109 males and 43 females; mean age 60.1 +/- 8.6 years) who underwent elective CABG on CPB between January and September 2011. Early postoperative morbidity and mortality rates were compared between subjects with and without the MS. Diagnosis of the MS was based on the American National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. RESULTS: Of the study group, 64 patients (42%) had the MS. The two groups were similar in age and gender. In the postoperative period, rates of atrial fibrillation, wound infection, pulmonary complications, and lengths of intubation, hospitalisation and intensive care unit stay were significantly higher in MS patients (p < 0.01). The MS was significantly associated with wound infection (OR 6.64, 95% CI: 1.72-25.75), pulmonary complications (OR 6.44, 95% CI: 1.58-26.33), arrhythmia (OR 5.47, 95% CI: 1.50-19.97) and prolonged intubation (OR 1.17, 95% CI: 1.05-1.32). The mortality rate was 3.1% in the MS group and 1.1% in the non-MS group, with no significant difference (p > 0.05). CONCLUSION: The MS was associated with a higher rate of early postoperative morbidity following CABG, without having a significant effect on the mortality rate.

AB - INTRODUCTION: Heart failure is a common cause of hospitalisation and therefore contributes to in-hospital outcomes such as mortality. In this study we describe patient characteristics and outcomes of acute heart failure (AHF) in Botswana. METHODS: Socio-demographic, clinical and laboratory data were collected from 193 consecutive patients admitted with AHF at Princess Marina Hospital in Gaborone between February 2014 and February 2015. The length of hospital stay and 30-, 90- and 180-day in-hospital mortality rates were assessed. RESULTS: The mean age was 54 +/- 17.1 years, and 53.9% of the patients were male. All patients were symptomatic (77.5% in NYHA functional class III or IV) and the majority (64.8%) presented with significant left ventricular dysfunction. The most common concomitant medical conditions were hypertension (54.9%), human immuno-deficiency virus (HIV) (33.9%), anaemia (23.3%) and prior diabetes mellitus (15.5%). Moderate to severe renal dysfunction was detected in 60 (31.1%) patients. Peripartum cardiomyopathy was one of the important causes of heart failure in female patients. The most commonly used treatment included furosemide (86%), beta blockers (72.1%), angiotensin converting enzyme inhibitors (67.4%), spironolactone (59.9%), digoxin (22.1%), angiotensin receptor blockers (5.8%), nitrates (4.7%) and hydralazine (1.7%). The median length of stay was nine days, and the in-hospital mortality rate was 10.9%. Thirty-, 90- and 180-day case fatality rates were 14.7, 25.8 and 30.8%, respectively. Mortality at 180 days was significantly associated with increasing age, lower haemoglobin level, lower glomerular filtration rate, hyponatraemia, higher N-terminal pro-brain natriuretic peptide levels, and prolonged hospital stay. CONCLUSIONS: AHF is a major public health problem in Botswana, with high in-hospital and post-discharge mortality rates and prolonged hospital stays. Late and symptomatic presentation is common, and the most common aetiologies are preventable and/or treatable co morbidities, including hypertension, diabetes mellitus, renal failure and HIV. PMID- 27701483 TI - A rare giant pericardial cyst mimicking a paracardiac mass. AB - Pericardial cysts are rare benign lesions of the thoracic cavity and are mostly congenital anomalies. They are induced by an incomplete coalescence of foetal lacunae during the development of the pericardium. Pericardial cysts are usually unilocular, well marginated spherical or teardrop shaped and may be attached to the pericardium directly or by a pedicle. Of all pericardial cysts, 70 to 75% are located at the right cardiophrenic angle. We report a case that was incidentally diagnosed with only chest magnetic resonance imaging because of a paracardiac mass. In order to prevent complications, the giant pericardial cyst was excised outside of the pericardium with median sternotomy. PMID- 27701485 TI - Pre-anesthetic echocardiographic findings in children undergoing non-cardiac surgery at the University of Benin Teaching Hospital, Nigeria. AB - BACKGROUND: A pre-anaesthestic echocardiogram (echo) is requested for most non cardiac surgeries to identify possible cardiac structural anomalies. OBJECTIVE: To describe the prevalence and spectrum of structural cardiac abnormalities seen in various non-cardiac conditions. METHODS: We carried out a retrospective review of pre-anaesthetic echos performed over five years on children scheduled for non cardiac surgery. The requests were categorised according to referring specialities, and the biodata and echo findings were noted. RESULTS: A total of 181 children and 181 echocardiograms were studied, and 100 (55.2%) of the patients were male. Most of the children (87, 48.1%) with oro-facial clefts were referred from dentistry. Of the 181 children, 39 (21.5%) had cardiac abnormalities, most (34, 87.2%) of whom had congenital heart disease (CHD). Ophthalmic requests with suspected congenital rubella syndrome (CRS) had the highest prevalence of 8/12 (66.7%) while the lowest was oro-facial clefts at 15/87 (17.2%). Atrial septal defect was the commonest abnormality, found in 14 patients (35.9%). CONCLUSION: Pre-anaesthetic echo should be performed, especially for children with suspected CRS and other congenital anomalies, requiring non-cardiac surgery. PMID- 27701484 TI - Comparative analysis of anthropometric indices of obesity as correlates and potential predictors of risk for hypertension and prehypertension in a population in Nigeria. AB - BACKGROUND: Obesity is a well-established independent risk factor for hypertension and other cardiometabolic disorders. However, the best anthropometric index of obesity that predicts or associates strongly with hypertension and related conditions remains controversial and inconclusive. OBJECTIVE: This study compared the performance of eight anthropometric indices of obesity: body mass index (BMI), ponderal index (PI), waist circumference (WC), hip circumference (HC), waist-hip ratio (WHR), waist-height ratio (WHtR), body adiposity index (BAI) and conicity index (CI) as correlates and potential predictors of risk of hypertension and prehypertension in a Nigerian population, and also the possible effect of combining two or more indices in that regard. METHODS: This church-based, cross-sectional study was conducted in Anambra state, south-eastern Nigeria from 2012 to 2013. A total of 912 persons (436 male and 476 female) drawn randomly from three major cities (Awka, Onitsha and Nnewi) in the state participated in the study. Information on demography, medical history and lifestyle were obtained using a well-structured and validated questionnaire. The systolic/diastolic blood pressure and anthropometric measurements were taken by well-trained personnel. The resulting data were analysed using descriptive statistics, logistic regression, Poisson regression and receiver operating characteristic curve analysis. RESULTS: The mean values of all the anthropometric indices studied increased from normotension, through prehypertension to hypertension in both genders. BMI, WC, HC and CI were significantly higher (p < 0.05) in females than males. All the anthropometric indices studied were significantly (p < 0.001 except for CI) correlated with systolic and diastolic blood pressure. BMI, WHtR, WC and PI (with higher correlation coefficients for blood pressure) showed the best potential to predict hypertension and prehypertension in the study: BMI (cut-off = 24.49, AUC = 0.698; cut-off = 23.62, AUC = 0.659), WHtR (cut-off = 0.55, AUC = 0.682; cut-off = 0.5, AUC = 0.636), WC (cut-off = 91.44, AUC = 0.692; cut-off = 82.55, AUC = 0.645), PI (cut-off = 14.45, AUC = 0.670; cut-off = 13.69, AUC = 0.639), in males; and BMI (cut-off = 24.44, AUC = 0.622; cut-off = 28.01, AUC = 0.609), WHtR (cut-off = 0.51, AUC = 0.624; cut-off = 0.6, AUC = 0.572), WC ( cut-off = 96.62, AUC = 0.616; cut-off = 96.52, AUC = 0.584), PI ( cut-off = 16.38, AUC = 0.619; cut-off = 17.65, AUC = 0.599), in females for hypertension and prehypertension, respectively. In predicting hypertension risk, WC and WHtR did not significantly improve the performance of BMI in the models when included using our decision rule. Overall, CI had a very poor discriminatory power for both conditions in this study. CONCLUSION: BMI, WHtR, WC and PI emerged the best predictors of hypertension risk, and BMI, WC and PI of prehypertension risk in this study. The combination of high-performing anthropometric indices in a model did not improve their performance. Therefore we recommend the simultaneous but independent use of BMI and either WC or WHtR for predicting hypertension, and BMI and WC for prehypertension risk, bearing in mind that both types of index (abdominal and general obesity) account for different forms of obesity. PMID- 27701486 TI - Relationship between Vitamin D and the development of atrial fibrillation after on-pump coronary artery bypass graft surgery. AB - BACKGROUND: Vitamin D deficiency is associated with many diverse cardiovascular disorders, such as hypertension, heart failure, stroke, coronary artery disease and atrial fibrillation. The relationship between Vitamin D and the development of atrial fibrillation after coronary artery bypass surgery (CABG) has not been studied. Therefore, we assessed the relationship between Vitamin D and the development of postoperative atrial fibrillation (POAF) after CABG. METHODS: Medical records of consecutive patients who underwent CABG surgery were retrospectively reviewed for the development of atrial fibrillation in the postoperative period. Vitamin D, other biochemical parameters, and clinical and echocardiographic parameters were evaluated in all patients. The independent variables for the development of postoperative atrial fibrillation were defined and their predictive values were measured. RESULTS: The study group consisted of 128 patients, of whom 41 (32%) developed POAF. Age, diabetes mellitus, chronic obstructive pulmonary disease, history of transient ischaemic attack/stroke, heart failure, left atrial diameter, platelet:largecell ratio, and creatinine, urea, uric acid, calcium and potassium levels were identified as important variables for the development of POAF. However, with logistic regression analysis, chronic obstructive pulmonary disease (OR: 28.737, 95% CI: 0.836 16.118, p < 0.001), heart failure (OR: 15.430, 95% CI: 0.989-7.649, p = 0.006), diabetes mellitus (OR: 11.486, 95% CI: 0.734-11.060, p = 0.001) and left atrial diameter (OR: 1.245, 95% CI: 0.086-6.431, p = 0.011) appeared as independent variables predicting the development of POAF. CONCLUSION: In our study, although there was a significant negative correlation between Vitamin D and left atrial diameter, Vitamin D level was not an independent predictor for POAF. PMID- 27701487 TI - The effect of proximal anastomosis on the expansion rate of a dilated ascending aorta in coronary artery bypass surgery: a prospective study. AB - BACKGROUND: This study was designed to determine the short- and long-term effects of proximal aortic anastomosis, performed during isolated coronary artery bypass grafting (CABG) in patients with dilatation of the ascending aorta who did not require surgical intervention. METHODS: The study was performed on 192 (38 female and 160 male patients; mean age, 62.1 +/- 9.2 years; range, 42-80 years) patients with dilatation of the ascending aorta who underwent CABG surgery between 1 June 2006 and 31 May 2014. In group 1 (n = 114), the saphenous vein and left internal mammarian artery grafts were used, and proximal anastomosis was performed on the ascending aorta. In group 2 (n = 78), left and right internal mammarian artery grafts were used, and proximal aortic anastomosis was not performed. Pre operatively and in the first and third years postoperatively, the ascending aortic diameter was measured and recorded using transthoracic echocardiography at four different regions (annulus, sinus of Valsalva, sinotubular junction and tubular aorta). RESULTS: A statistically significant difference was found between the groups for the number of grafts used and the duration of aortic cross clamping and cardiopulmonary bypass. No significant intergroup difference was seen for the mean diameter of the ascending aorta (p > 0.05). Annual changes in the aortic diameter were found to be extremely significantly different in both groups (p = 0.0001). Mean values of the aortic diameter at the level of the sinotubular junction and tubular ascending aorta, mean aortic diameters (p = 0.002 and p = 0.0001, respectively), annual increase in diameter (p = 0.0001 and p = 0.0001, respectively), and mean annual difference in diameter (p = 0.0001 and p = 0.0001, respectively) at one and three years postoperatively were statistically significantly different between the groups. CONCLUSION: In patients with ascending aortic dilatation who did not require surgical intervention and who had proximal anastomosis of the ascending aorta and underwent only CABG, we detected statistically significant increases in the diameter of the sinotubular junction and tubular aorta up to three years postoperatively. PMID- 27701488 TI - Xanthine oxidase inhibitors in ischaemic heart disease. AB - Increased uric acid levels are correlated with cardiovascular disease, particularly with ischaemic heart disease. Xanthine oxidase inhibitors, especially allopurinol, lower the risk of ischaemic heart disease due to their effects on reactive oxygen species and endothelial function. In chronic stable angina pectoris, allopurinol increases the median time to ST depression, time to chest pain, and total exercise time. On the other hand, it has been reported that allopurinol has a beneficial effect on ischaemic patients referred for angioplasty, but there are insufficient data regarding its effect on acute myocardial infarction patients. Moreover, other important actions of allopurinol are regression of left ventricular hypertrophy and improvement in the results of cardiac rehabilitation. The efficacy of allopurinol has recently been acknowledged by the European Society of Cardiology guidelines for stable angina pectoris, but the particular role of allopurinol in ischaemic heart disease patients is not fully established. PMID- 27701489 TI - Prevalence of selected cardiometabolic risk factors among adults in urban and semi-urban hospitals in four sub-Saharan African countries. AB - AIM: Cardiovascular diseases (CVDs) are a global challenge but the burden in sub Saharan African (SSA) countries is less well documented than elsewhere. We aimed to describe the key cardiometabolic risk factors in four SSA countries. METHODS: A cross-sectional, multi-national, hospital-based study was carried out among adults (> 35 years) across four SSA countries from 12 December 2011 to 7 February 2013. Risk factors were defined using the World Health Organisation and International Diabetes Federation guidelines. RESULTS: Of the 844 adults (57.4% female, mean age 52.6 years), 76.6% were urban residents. The predominant CVD risk factors were hypertension (74.1%), obesity (36.2%) and excessive alcohol consumption (25.6%). Diabetes (17.7 vs 10.0%), obesity (42.8 vs 16.8%) and hypercholesterolaemia (25.8 vs 18.0%) were more prevalent among the hypertensive subjects (all p < 0.007) than the normotensives. The metabolic syndrome (39.4%) was more common in women and hypertensive subjects. CONCLUSIONS: Hospital patients in SSA countries present with excessive rates of cardiometabolic risk factors. Focus on their prevention and control is warranted. PMID- 27701491 TI - In memoriam. Prof. Dr. Maria Beatriz Guglielmotti. PMID- 27701490 TI - Audit of availability and distribution of paediatric cardiology services and facilities in Nigeria. AB - BACKGROUND: Paediatric cardiac services in Nigeria have been perceived to be inadequate but no formal documentation of availability and distribution of facilities and services has been done. OBJECTIVE: To evaluate and document the currently available paediatric cardiac services in Nigeria. METHODS: In this questionnaire-based, cross-sectional descriptive study, an audit was undertaken from January 2010 to December 2014, of the personnel and infrastructure, with their distributions according to geopolitical zones of Nigeria. RESULTS: Forty eight centres participated in the study, with 33 paediatric cardiologists and 31 cardiac surgeons. Echocardiography, electrocardiography and pulse oximetry were available in 45 (93.8%) centres while paediatric intensive care units were in 23 (47.9%). Open-heart surgery was performed in six (12.5%) centres. South-West zone had the majority of centres (20; 41.7%). CONCLUSIONS: Available paediatric cardiac services in Nigeria are grossly inadequate and poorly distributed. Efforts should be intensified to upgrade existing facilities, establish new and functional centres, and train personnel. PMID- 27701492 TI - Repairability of aged resin composites mediated by different restorative systems. AB - The aim of this study was to evaluate the shear bond strength of resin composite repairs with and without aging of the surface to be repaired, using different adhesive systems and resin composites. Ninety specimens were prepared: 10 for the Control Group (GC - without repair); 40 for Group I (GI - repairs after 7 days) and 40 for Group II (GII - repairs after 180 days). Groups I and II were divided into 4 subgroups of 10 specimens each, according to the adhesive system and composite resin used: A) Adper Scotch Bond Multipurpose + Filtek Z350 XT; B) Adper Single Bond Plus + Filtek Z350 XT; C) Adper Scotch Bond Multipurpose + Esthet-X; D) Adper Single Bond Plus + Esthet-X. The specimens were tested for shear strength in a universal testing machine. The results were analyzed by two factor one-way ANOVA and Fisher's post hoc tests (alpha=0.05). The control group had better performance than the other groups. There was no significant difference when comparing different adhesive systems and composite resins. Repairs performed at 7 days were better than those performed at 180 days. The composite repairs decreased the mechanical strength of the restoration. Aging of the resin substrate may decrease repair bond strength over time, regardless of the type of adhesive systems and resin composites used. PMID- 27701493 TI - Study and analysis of information technology in dentistry in Latin American countries. AB - : Dentistry increasingly uses Information and Communication Technology (ICT), which has impact on teaching, research, the profession and dental care in general. However, there is a lack of valid information on ICT resources and use in Latin America. This was a descriptive, cross-sectional, multi-center, interdisciplinary study, the aim of which was to conduct a survey on how extensively ICT is used in Dentistry in Latin American countries by enquiring into two primary components: 1) use of ICT in student training and 2) use of ICT by professionals in consulting rooms and services. Two questionnaires on ICT were prepared: one for teachers/researchers and another for students/professionals. We received 94 answers from teachers/researchers at universities in the region providing information on ICT resources for teaching (type and implementation) and 221 answers from professionals (personal use and use in healthcare). Data are presented as absolute relative frequencies and analyzed quantitatively as percentages. RESULTS: 1) Teachers highlight ICT as an instrument for development, democratization and fairness in access to knowledge for higher education. 2) ICT supports collaborative learning and generates other innovative resources (e.g. simulators). 3) Innovations in telemedicine and experiences with electronic clinical history were identified in Brazil, Uruguay and Colombia. These results are a basis upon which to reach a consensus regarding a set of ICT indicators which are comparable at regional level and serve as input to unify the design and implementation of ICTs experiences in both teaching and dental care in Latin America. PMID- 27701494 TI - Craniofacial pain can be the sole prodromal symptom of an acute myocardial infarction: an interdisciplinary study. AB - We recently found craniofacial pain to be the sole symptom of an acute myocardial infarction (AMI) in 4% of patients. We hypothesized that this scenario is also true for symptoms of prodromal (pre-infarction) angina. We studied 326 consecutive patients who experienced myocardial ischemia. Intra-individual variability analyses with respect to ECG findings and pain characteristics were performed for those 150 patients who experienced at least one recurrent ischemic episode. AMI patients (n=113) were categorized into two subgroups: "abrupt onset" (n=81) and "prodromal angina" (n=32). Age, gender and risk factor comparisons were performed between groups. Craniofacial pain constituted the sole prodromal symptom of an AMI in 5% of patients. In those who experienced two ischemic episodes, women were more likely than men to experience craniofacial pain in both episodes (p<0.01). There was no statistically significant difference between episodes regarding either ECG findings or the use of the two typical pain quality descriptors "pressure" and "burning". This study is to our knowledge the first to report that craniofacial pain can be the only symptom of a pre-infarction angina. Craniofacial pain constitutes the sole prodromal AMI symptom in one out of 20 AMI patients. Recognition of this atypical symptom presentation is low because research on prodromal AMI symptoms has to date studied only patients with chest pain. To avoid a potentially fatal misdiagnosis, awareness of this clinical presentation needs to be brought to the attention of clinicians, researchers and the general public. PMID- 27701496 TI - Post-bleaching sensitivity in patients with sickle cell disease. AB - Sickle cell disease (SCD) is a monogenic disease that affects millions of people worldwide. This study analyzed the effectiveness of bleaching and tooth sensitivity after in-office bleaching in patients with SCD. Forty volunteers were randomly assigned to four groups of 10 patients each (five with the SCD and five healthy controls) and treated using in-office bleaching with 35% hydrogen peroxide and different light activation protocols. No statistically significant difference was observed with relation to presence of tooth sensitivity, with or without use of a source of light for peroxide activation, and all bleaching therapies were effective, regardless of the technique employed and the presence/absence of sickle cell disease. The data showed that in-office dental bleaching is a viable alternative for improvement of oral esthetics for patients with SCD. PMID- 27701495 TI - Association between periodontal disease and endothelial dysfunction in smoking patients. AB - Over the past two decades, there has been increasing interest in the impact of oral health on cardiovascular disease, particularly regarding the effects of chronic infections such as periodontitis on the endothelium. The aim of this study was to evaluate in healthy smokers whether there are any significant differences in the frequency of endothelial dysfunction between subjects with chronic moderate to severe periodontal disease and periodontally healthy subjects. An observational cross-sectional study was conducted. The target population was adults older than 40 years of age. Blood tests were performed to determine values of CBC, glycaemia, total cholesterol, HDL-C, and LDLC. Periodontal examinations and probing were conducted with a Florida Probe(r), and standardized procedures were used to measure flow-mediated dilation. Out of 150 subjects [69 male (46%) and 81 female (54%)], 75 (50%) had chronic periodontitis. The mean value for baseline flow-mediated dilation was 4.04% and the mean value for final flow-mediated dilation was 4.66%, with a 0.62% mean difference showing a statistically significant increase (p<0.001).This study found no significant difference in the flow-mediated dilation values between periodontally healthy subjects and those with periodontitis, in contrast to the literature, which suggests a negative impact of periodontal disease on endothelial function. PMID- 27701497 TI - Nickel allergy: blood and periodontal evaluation after orthodontic treatment. AB - The aim of this study was to assess periodontal status and blood parameters in orthodontic patients with nickel allergy one month after removal of brackets. Ninety-six randomly selected patients were initially evaluated. Allergy to nickel was diagnosed using a patch test. After determining the prevalence of subjects allergic to nickel, two groups were formed: 16 allergic (experimental) and 16 non allergic (control) patients. Their periodontal status was determined regularly by a single, blinded, duly calibrated examiner using the Loe Index (GI) and their blood was tested (complete blood test, including nickel and IgE levels) after nine months of orthodontic treatment and again one month after removing the orthodontic appliances. Statistical analyses included paired and non-paired t tests, Mann-Whitney, Wilcoxon, McNemar and linear trend chi-square tests (p<=0.05). Comparison of the values recorded during orthodontic treatment and one month after removing the appliances showed that in the allergic group there was significant increase in eosinophils (p=0.046), basophils (p=0.001) and monocytes (p=0.002), and decrease in number of bands (p=0.000), while in the control group, there was increase in lymphocytes (p=0.039) and decrease in segmented neutrophils (p=0.030) and IgE levels (p=0.001). In both groups, plasma nickel levels increased (p=0.010; p=0.039) and GI scores decreased. One month after removing the brackets, blood and periodontal parameters from patients with and without nickel allergy were similar. PMID- 27701498 TI - Creatine metabolism: detection of creatine and guanidinoacetate in saliva of healthy subjects. AB - Creatine (Cr) plays an important role in storage and transmission of phosphate bound energy. Cerebral creatine deficiency syndromes comprise three inherited defects in Cr biosynthesis and transport. The aim of this study was to investigate whether Cr and Guanidinoacetate (GAA) can be detected in saliva of healthy subjects and to establish the relationship between salivary and plasma levels of these molecules. An adapted gas chromatography (GC) method is described for the quantification of Cr and GAA biomarkers in saliva. Reference values were established for GAA and Cr in saliva. These values were age dependent (p= 0.001). No difference between genders was observed. We detected a difference between GAA and Cr concentrations in saliva and in plasma. The GC method for simultaneous determination of GAA and Cr in human saliva is fast, reliable, sensitive, non invasive and precise to use as a biochemical approach in early detection of cerebral creatine deficiency syndromes. PMID- 27701499 TI - Frequency of the mesiopalatal canal in upper first permanent molars viewed through computed tomography. AB - The success of any endodontic therapy depends on factors such as correct diagnosis and prognosis. Unawareness or failure to locate additional canals, such as the mesiopalatal canal in the upper first molar, may lead to unsuccessful treatment. Hence, it is valid to consider all the resources available for locating this anatomic structure, e.g. the Cone-Beam Computed Tomography (CBCT). The purpose of this study was to verify the frequency of mesiopalatal canals in upper first permanent molars through computed tomography. Tomography images from a digital archive of a diagnostic imaging center were analyzed. Eighty (80) upper right first molars were assessed through CBCT in axial cross sections at 6mm and 3mm from the root apex; 40 were females and 40, males, randomly chosen. The results revealed that the mesiopalatal canals were present in 56.25% of the sections at 6mm from the root apex, and in 23.75% at 3mm from the apical limit. CBCT scan has proved to be a valid resource for locating mesiopalatal canal, especially in cases where location was not feasible through clinical means. PMID- 27701500 TI - Effect of angiotensin-converting enzyme inhibitors on vascular endothelial function in hypertensive patients after intensive periodontal treatment. AB - : There is a relation between vascular endothelial function, atherosclerotic disease, and inflammation. Deterioration of endothelial function has been observed twenty-four hours after intensive periodontal treatment. This effect may be counteracted by the action of angiotensin-converting enzyme inhibitors, which improve endothelial function. The aim of the present study was to evaluate vascular endothelial function after intensive periodontal treatment, in hypertensive patients treated with angiotensinconverting enzyme inhibitors. A prospective, longitudinal, comparative study involving repeated measurements was conducted. Fifty-two consecutive patients with severe periodontal disease were divided into two groups, one comprising hypertensive patients treated with converting enzyme inhibitors and the other comprising patients with no clinical signs of pathology and not receiving angiotensin-converting enzyme inhibitors. Endothelial function was assessed by measuring postischemic dilation of the humeral artery (baseline echocardiography Doppler), and intensive periodontal treatment was performed 24h later. Endothelial function was re-assessed 24h and 15 days after periodontal treatment. STATISTICAL ANALYSIS: Results were analyzed using the SPSS 20 statistical software package. Student's t test and MANOVA were calculated and linear regression analysis with 95% confidence intervals and alpha<0.05 was performed. Arterial dilation at 24 hours was lower compared to baseline in both groups; values corresponding to the groups receiving angiotensin converting enzyme inhibitors were 11.89 +/- 4.87 vs. 7.30 +/- 2.90% (p<0.01) and those corresponding to the group not receiving ACE inhibitors were 12.72 +/- 4.62 vs. 3.56 +/- 2.39 (p<0.001). The differences between groups were statistically significant (p<0.001). CONCLUSION: The increase in endothelial dysfunction after intensive periodontal treatment was significantly lower in hypertensive patients treated with angiotensin-converting enzyme inhibitors. Endothelial function improved 15 days after periodontal treatment, reaching baseline values. These results support the protective effect of angiotensin converting enzyme inhibitors on the endothelial function after intensive periodontal treatment. PMID- 27701501 TI - Dental bleaching with ozone: effects on color and enamel microhardness. AB - The aim of this in vitro study was to evaluate the effects of dental bleaching with ozone (O3) on color change and enamel microhardness. Enamel blocks (3 x 3 x 3mm) were randomly distributed for treatments (n=10). Color change (DeltaE) and Knoop microhardness of the enamel blocks were evaluated before and after the following treatments: C - deionized water (control); HP - 37.5% hydrogen peroxide (Pola Office+/ SDI); PLA - placebo gel; O3 - ozone; and O2 - oxygen. Four 8 minute applications were used for HP and PLA, and one 19-minute application for O3 and O2.One-way ANOVA revealed that DeltaE was not significantly influenced by the treatment (p = 0.112). For the treatments with HP, PLA, O3 andO2, DeltaE was greater than 3.3. The paired t test showed significant decrease in microhardness after treatments (p < 0.001) but no significant difference between treatments (ANOVA; p = 0.313). Dental bleaching treatments with O3, HP, O2 and PLA induced enamel color changes that may be clinically discernible, although enamel microhardeness decreased.

AB - The purpose of this study was to assess the efficacy of the thermoplastic filling techniques, Touch'n Heat(r), TC(r) System and Tagger's Hybrid Technique, in oval shaped canals at the apical third.Thirty-three human uniradicular lower pre-molar teeth were treated by the reciprocating movement technique and were subsequently split into 3 groups, according to the filling technique performed:Touch'n Heat (TH), TC System (TC) and the Tagger's Hybrid Technique (TG).In the sequence, the teeth were sectioned at 2mm and 4mm from the foramen and images were taken to measure the percentage of canal area filled with the obturation materials as well as void spaces.Data were submitted for Kruskal-Wallis statistical analysis. Irrespective of levels, data showed that the TC System delivered the best results.(p<0,001).At 2mm and 4mm levels, there was no difference between the TG technique and the TH technique (p<0,001).With all the techniques and at all levels, no differences were observed regarding the void area variable.(p>0,001).The techniques evaluated showed an adequate filling with obturation materials and the TC has reached the highest filling with the guta percha material. PMID- 27701503 TI - Toothbrushing procedure in schoolchildren with no previous formal instruction: variables associated to dental biofilm removal. AB - The aim of this study was to establish the association between features regarding brushing procedure performed by schoolchildren without previous formal training and the effectiveness of biofilm removal. Out of a population of 8900 6- and 7 year-old schoolchildren in Buenos Aires City, 600 children were selected from schools located in homogeneous risk areas. Informed consent was requested from parents or guardians and formal assent was obtained from children themselves. The final sample consisted of 316 subjects. The following tooth brushing variables were analyzed: toothbrush-gripping, orientation of active part of bristles with respect to the tooth, type of movement applied, brushing both jaws together or separately, including all 6 sextants and duration of brushing. The level of dental biofilm after brushing was determined by O'Leary's index, acceptable cut off point = 20%. Four calibrated dentists performed observations and clinical examinations. Frequency distribution, central tendency and dispersion measures were calculated. Cluster analyses were performed; proportions of variables for each cluster were compared with Bonferroni's correction and OR was obtained. The most frequent categories were: palm gripping (71.51%); perpendicular orientation (85.8%); horizontal movement (95.6%); separate addressing of jaws (68%) and inclusion of all 6 sextants (50.6%). Mean duration of brushing was 48.78 +/- 27.36 seconds. 42.7% of the children achieved an acceptable biofilm level. The cluster with the highest proportion of subjects with acceptable post-brushing biofilm levels (p<0.05) differed significantly from the rest for the variable "inclusion of all 6 sextants in brushing procedure". OR was 2.538 (CI 95% 1.603 - 4.017). Inclusion of all six sextants could be a determinant variable for the removal of biofilm by brushing in schoolchildren, and should be systematized as a component in oral hygiene education.

AB - We have designed a new device that combines sample collection, transportation, culture and detection of Group B Streptococcus (GBS), requiring no additional processing in the clinical laboratory. The objective was to evaluate the performance of this device for GBS detection in pregnant women. The new prototype was compared to direct plating of vaginal-rectal swabs onto Granada solid media plates. Direct plating method detected 124 positive samples out of 600 (20.6%) whereas the new device detected 10 additional positive samples (134/600, 22.3%). This new device (patent-protected) could be considered for routine GBS screening. PMID- 27701616 TI - Pneumonia: burden of disease.

AB - OBJECTIVE: Different subtypes of Campylobacter spp. have been associated with diarrhoea and a Multilocus Sequence Typing (MLST) method has been performed for subtyping. In the present work, MLST was used to analyse the genetic diversity of eight strains of Campylobacter coli. METHODS: Nineteen genetic markers were amplified for MLST analysis: AnsB, DmsA, ggt, Cj1585c, CJJ81176-1367/1371, Tlp7, cj1321-cj1326, fucP, cj0178, cj0755/cfrA, ceuE, pldA, cstII, cstIII. After comparing the obtained sequences with the Campylobacter MLST database, the allele numbers, sequence types (STs) and clonal complexes (CCs) were assigned. RESULTS: The 8 C. coli isolates yielded 4 different STs belonging to 2 CCs. Seven isolates belong to ST-828 clonal complex and only one isolate belong to ST-21. Two samples came from the same patient, but were isolated in two different periods of time. CONCLUSIONS: MLST can be useful for taxonomic characterization of C. coli isolates.

PMID- 27701622 TI - Regeneration of Corneal Epithelium With Dental Pulp Stem Cells Using a Contact Lens Delivery System. AB - Purpose: The corneal epithelium is sloughed off surface of the eye by the action of blinking and is continually replaced by division and maturation of the limbal stem cells (LSCs). In the case of injury or disease, LSCs can be lost or damaged to a point at which the corneal epithelial layer is no longer maintained. leading to LSC deficiencies (LSCDs). When this occurs, the opaque conjunctiva overgrows the anterior surface of the eye, leading to vision impairment or loss. Dental pulp stem cells (DPSCs) are promising candidates as autologous LSC substitutes. In this study, contact lenses (CLs) are used as a novel medical device to deliver DPSCs onto corneal surface to enhance corneal epithelium regeneration. Methods: Dental pulp stem cells labeled with green fluorescent Qtracker 525 were seeded onto the pretreated CLs, allowed to adhere, then delivered to debrided human corneas. Expression of KRT3, 12, 13, and 19 was investigated by immunostaining, then standard and confocal microscopy. Results: Dental pulp stem cells were successfully isolated, labeled, and delivered to the corneal surface using CLs. Following removal of CLs, confocal microscopy showed that the DPSCs had migrated onto the cornea. Coexpression of KRT12 and green fluorescent Qtracker 525 confirmed that the DPSCs had transdifferentiated into corneal epithelial progenitors. Delimitation of KRT 19 and green fluorescence provides evidence that Qtracker 525-labeled DPSCs establish a barrier to the invasion of the cornea by conjunctiva. Conclusions: In this study we show that DPSCs, delivered using CLs, can be used to enhance repair and regeneration of the human corneal epithelium. PMID- 27701623 TI - Association Between Tracheal Intubation During Pediatric In-Hospital Cardiac Arrest and Survival. AB - Importance: Tracheal intubation is common during pediatric in-hospital cardiac arrest, although the relationship between intubation during cardiac arrest and outcomes is unknown. Objective: To determine if intubation during pediatric in hospital cardiac arrest is associated with improved outcomes. Design, Setting, and Participants: Observational study of data from United States hospitals in the Get With The Guidelines-Resuscitation registry. Pediatric patients (<18 years) with index in-hospital cardiac arrest between January 2000 and December 2014 were included. Patients who were receiving assisted ventilation, had an invasive airway in place, or both at the time chest compressions were initiated were excluded. Exposures: Tracheal intubation during cardiac arrest . Main Outcomes and Measures: The primary outcome was survival to hospital discharge. Secondary outcomes included return of spontaneous circulation and neurologic outcome. A favorable neurologic outcome was defined as a score of 1 to 2 on the pediatric cerebral performance category score. Patients being intubated at any given minute were matched with patients at risk of being intubated within the same minute (ie, still receiving resuscitation) based on a time-dependent propensity score calculated from multiple patient, event, and hospital characteristics. Results: The study included 2294 patients; 1308 (57%) were male, and all age groups were represented (median age, 7 months [25th-75th percentiles, 21 days, 4 years]). Of the 2294 included patients, 1555 (68%) were intubated during the cardiac arrest. In the propensity score-matched cohort (n = 2270), survival was lower in those intubated compared with those not intubated (411/1135 [36%] vs 460/1135 [41%]; risk ratio [RR], 0.89 [95% CI, 0.81-0.99]; P = .03). There was no significant difference in return of spontaneous circulation (770/1135 [68%] vs 771/1135 [68%]; RR, 1.00 [95% CI, 0.95-1.06]; P = .96) or favorable neurologic outcome (185/987 [19%] vs 211/983 [21%]; RR, 0.87 [95% CI, 0.75-1.02]; P = .08) between those intubated and not intubated. The association between intubation and decreased survival was observed in the majority of the sensitivity and subgroup analyses, including when accounting for missing data and in a subgroup of patients with a pulse at the beginning of the event. Conclusions and Relevance: Among pediatric patients with in-hospital cardiac arrest, tracheal intubation during cardiac arrest compared with no intubation was associated with decreased survival to hospital discharge. Although the study design does not eliminate the potential for confounding, these findings do not support the current emphasis on early tracheal intubation for pediatric in-hospital cardiac arrest. PMID- 27701624 TI - Work-Related Determinants of Voice Complaints Among School Workers: An Eleven Month Follow-Up Study. AB - Purpose: We determined the natural course of voice complaints among school workers and established the risk factors associated with incidence and chronic voice complaints. Method: We conducted a longitudinal study with an 11-month follow-up among 682 school workers. Participants filled out a questionnaire on individual and work-related conditions and the nature and severity of voice complaints. All participants who provided baseline data were contacted in the 11 month follow-up, if they were still working in the school. Short-term environmental measurements of physical work-related factors were conducted during visits at the workplaces. Logistic regression analysis was used to determine associations between work-related factors and voice complaints. Results: We found a high occurrence of chronic voice complaints, a low recovery of 22%, and an annual incidence of 44%. A self-reported high noise level at the workplace was associated with the incidence of voice complaints (odds ratio = 2.45). Self reported poor acoustics in the classroom was associated with chronic voice complaints (odds ratio = 1.76). Conclusions: This unique longitudinal study among school workers presented some indications that self-reported high noise levels may contribute to the incidence of voice complaints, whereas self-reported poor acoustic conditions may be an important associated factor of chronic voice complaints. PMID- 27701625 TI - The Home Literacy Environment and the English Narrative Development of Spanish English Bilingual Children. AB - Purpose: The purpose of this study was to examine the impact of the home literacy environment (HLE) on the English narrative development of Spanish-English bilingual children from low-income backgrounds. Method: Longitudinal data were collected on 81 bilingual children from preschool through 1st grade. English narrative skills were assessed in the fall and spring of each year. Microstructure measures included mean length of utterance in morphemes and number of different words. The Narrative Scoring Scheme (Heilmann, Miller, Nockerts, & Dunaway, 2010) measured macrostructure. Each fall, the children's mothers reported the frequency of literacy activities and number of children's books in the home. Growth curve modeling was used to describe the children's narrative development and the impact of the HLE over time. Results: Significant growth occurred for all narrative measures. The HLE did not affect microstructure growth. The frequency with which mothers read to their children had a positive impact on the growth of the children's total Narrative Scoring Scheme scores. Other aspects of the HLE, such as the frequency with which the mothers told stories, did not affect macrostructure development. Conclusions: These results provide information about the development of English narrative abilities and demonstrate the importance of frequent book reading for the overall narrative quality of children from Spanish-speaking homes who are learning English.

PMID- 27701626 TI - Gesture Use in 14-Month-Old Toddlers With Hearing Loss and Their Mothers' Responses. AB - Purpose: This study examined the gesture use of 14-month-old toddlers with hearing loss (HL) and mothers' responses to children's early gesture use. Comparisons were made to symbolic language and to dyads in which the toddler had normal hearing (NH). Method: Participants were 25 mother-toddler dyads in which the child had HL and a socioeconomic-status matched group of 23 mother-toddler dyads in which the child had NH. Thirty-minute mother-child interactions were video-recorded, transcribed for spoken language, sign, and gesture use, and coded for maternal responses to children's gestures. Mothers also reported on children's gestural and spoken language abilities. Results: Toddlers with HL used gesture similarly to their peers with NH, but demonstrated delays in spoken language. Spoken language and gesture were not significantly related for either group. Hearing levels were related to spoken language, but not gesture for the HL group. Maternal and child gesture were only related for signing mothers. Mothers of children with HL were more likely than their counterparts to provide no response to children's gestures. Conclusion: Although toddlers' gesture abilities remain intact in the presence of HL, mothers were not maximally responsive to those gestures and thus should be coached to increase their provision of contingent feedback. PMID- 27701628 TI - Effects of Biofeedback on Control and Generalization of Nasalization in Typical Speakers. AB - Purpose: The purpose of this study was to determine the effects of biofeedback on control of nasalization in individuals with typical speech. Method: Forty-eight individuals with typical speech attempted to increase and decrease vowel nasalization. During training, stimuli consisted of consonant-vowel-consonant (CVC) tokens with the center vowels /a/ or /i/ in either a nasal or nonnasal phonemic context (e.g., /mim/ vs. /bib/), depending on the participant's training group. Half of the participants had access to augmentative visual feedback during training, which was based on a less-invasive acoustic, accelerometric measure of vowel nasalization-the Horii oral-nasal coupling (HONC) score. During pre- and posttraining assessments, acoustically based nasalance was also measured from the center vowels /a/, /i/, /ae/, and /u/ of CVCs in both nasal and nonnasal contexts. Results: Linear regressions indicated that both phonemic contexts (nasal or nonnasal) and the presence of augmentative visual feedback during training were significant predictors for changes in nasalance scores from pre- to posttraining. Conclusions: Participants were able to change the nasalization of their speech following a training period with HONC biofeedback. Future work is necessary to examine the effect of such training in individuals with velopharyngeal dysfunction.

AB - Purpose: Dosage has been identified as an important element of treatment that may affect treatment efficacy. The purpose of this study was to examine the role of dose schedule for treatment of grammatical morphology deficits in children with specific language impairment (SLI). Method: Sixteen 4-to-5-year-old children with SLI participated in a 5-week intervention consisting of equivalent daily Enhanced Conversational Recast treatment (Plante et al., 2014) targeting grammatical morphology. Half of the children received treatment in one 30-min session (massed condition). Half received treatment in three 10-min sessions (spaced condition) within one 4-hr period. Progress was assessed 3 times weekly by probing a child's use of his or her treatment morpheme and untreated morpheme (a maturational control) in untreated contexts. Results: Pre- to posttreatment morpheme usage differed significantly for children regardless of dosage condition, and pre to post usage of an untreated morpheme was unchanged, demonstrating overall treatment efficacy. There were no differences in treatment effects for the massed and spaced conditions. Conclusions: The study adds to evidence that Enhanced Conversational Recast can produce positive results in a short period of time for children with SLI. Furthermore, clinicians may have some flexibility in terms of the dose schedule they use to deliver this treatment in an evidence-based manner. PMID- 27701631 TI - Improved Automated Detection of Diabetic Retinopathy on a Publicly Available Dataset Through Integration of Deep Learning. AB - Purpose: To compare performance of a deep-learning enhanced algorithm for automated detection of diabetic retinopathy (DR), to the previously published performance of that algorithm, the Iowa Detection Program (IDP)-without deep learning components-on the same publicly available set of fundus images and previously reported consensus reference standard set, by three US Board certified retinal specialists. Methods: We used the previously reported consensus reference standard of referable DR (rDR), defined as International Clinical Classification of Diabetic Retinopathy moderate, severe nonproliferative (NPDR), proliferative DR, and/or macular edema (ME). Neither Messidor-2 images, nor the three retinal specialists setting the Messidor-2 reference standard were used for training IDx DR version X2.1. Sensitivity, specificity, negative predictive value, area under the curve (AUC), and their confidence intervals (CIs) were calculated. Results: Sensitivity was 96.8% (95% CI: 93.3%-98.8%), specificity was 87.0% (95% CI: 84.2% 89.4%), with 6/874 false negatives, resulting in a negative predictive value of 99.0% (95% CI: 97.8%-99.6%). No cases of severe NPDR, PDR, or ME were missed. The AUC was 0.980 (95% CI: 0.968-0.992). Sensitivity was not statistically different from published IDP sensitivity, which had a CI of 94.4% to 99.3%, but specificity was significantly better than the published IDP specificity CI of 55.7% to 63.0%. Conclusions: A deep-learning enhanced algorithm for the automated detection of DR, achieves significantly better performance than a previously reported, otherwise essentially identical, algorithm that does not employ deep learning. Deep learning enhanced algorithms have the potential to improve the efficiency of DR screening, and thereby to prevent visual loss and blindness from this devastating disease. PMID- 27701630 TI - Lentiviral Delivery of Small Hairpin RNA Targeting Connective Tissue Growth Factor Blocks Profibrotic Signaling in Tenon's Capsule Fibroblasts. AB - Purposes: Trabeculectomy is a surgical procedure for lowering intraocular pressure in glaucoma patients, in which excessive scarring leading to failure of the filtering bleb adversely affects the surgical outcome. Heightened Tenon's capsule fibroblast (TCF) proliferation and extracellular matrix (ECM) deposition are implicated in this process but endogenous factors that regulate TCF functions remain largely elusive. This study sought to elucidate the role of connective tissue growth factor (CTGF) in the regulation of TCF phenotypes and signaling. Methods: Expression of CTGF in scarring and nonscarring Tenon's capsules was measured by real-time PCR and immunofluorescence. Knockdown of CTGC was achieved by lentivirus delivery of small-hairpin RNA. Cell proliferation was measured by CCK8, cell cycle progression, and apoptosis by flow cytometry, adhesion, migration, and invasion of TCF by functional assays in vitro. Proteins and cytokines related to fibrosis were measured by Western blot and ELISA, respectively. Results: Expression of CTGF was significantly upregulated in scarring Tenon's capsules and their isolated fibroblasts when compared with the nonfibrotic counterparts. Functionally, targeting CTGF with lentivirus-delivered small-hairpin RNA inhibited the proliferation, adhesion, migration, and invasion of TCFs, accompanied by downregulation of p38 and nuclear factor-kappaB as well as matrix metalloproteinase-2, cyclin D1, and collagen I. In addition, lentiviral targeting of CTGF reduced the release of fibrosis-related cytokines from TCFs and inhibited TCF-conditioned, medium-induced macrophage chemotaxis. Conclusions: Our study supports a crucial role of CTGF in the regulation of TCF proliferation and ECM deposition. Targeting CTGF using lentiviral vector may be a promising approach for preventing excessive scarring after trabeculectomy. PMID- 27701632 TI - An In Vitro Perfusion System to Enhance Outflow Studies in Mouse Eyes. AB - Purpose: The molecular mechanisms controlling aqueous humor (AQH) outflow and IOP need much further definition. The mouse is a powerful system for characterizing the mechanistic basis of AQH outflow. To enhance outflow studies in mice, we developed a perfusion system that is based on human anterior chamber perfusion culture systems. Our mouse system permits previously impractical experiments. Methods: We engineered a computer-controlled, pump-based perfusion system with a platform for mounting whole dissected mouse eyes (minus lens and iris, ~45% of drainage tissue is perfused). We tested the system's ability to monitor outflow and tested the effects of the outflow-elevating drug, Y27632, a rho-associated protein kinase (ROCK) inhibitor. Finally, we tested the system's ability to detect genetically determined decreases in outflow by determining if deficiency of the candidate genes Nos3 and Cav1 alter outflow. Results: Using our system, the outflow facility (C) of C57BL/6J mouse eyes was found to range between 7.7 and 10.4 nl/minutes/mm Hg (corrected for whole eye). Our system readily detected a 74.4% Y27632-induced increase in C. The NOS3 inhibitor L-NG-nitroarginine methyl ester (L-NAME) and a Nos3 null mutation reduced C by 28.3% and 35.8%, respectively. Similarly, in Cav1 null eyes C was reduced by 47.8%. Conclusions: We engineered a unique perfusion system that can accurately measure changes in C. We then used the system to show that NOS3 and CAV1 are key components of mechanism(s) controlling outflow. PMID- 27701633 TI - Stimulation of a Suprachoroidal Retinal Prosthesis Drives Cortical Responses in a Feline Model of Retinal Degeneration. AB - Purpose: Retinal prostheses have emerged as a promising technology to restore vision in patients with severe photoreceptor degeneration. To better understand how neural degeneration affects the efficacy of electronic implants, we investigated the function of a suprachoroidal retinal implant in a feline model. Methods: Unilateral retinal degeneration was induced in four adult felines by intravitreal injection of adenosine triphosphate (ATP). Twelve weeks post injection, animals received suprachoroidal electrode array implants in each eye, and responses to electrical stimulation were obtained using multiunit recordings from the visual cortex. Histologic measurements of neural and glial changes in the retina at the implant site were correlated with cortical thresholds from individual stimulating electrodes. Results: Adenosine triphosphate-injected eyes displayed changes consistent with mid-to-late stage retinal degeneration and remodeling. A significant increase in electrical charge was required to induce a cortical response from stimulation of the degenerated retina compared to that in the fellow control eye. Spatial and temporal characteristics of the electrically evoked cortical responses were no different between eyes. Individual electrode thresholds varied in both the control and the ATP-injected eyes and were correlated with ganglion cell density. In ATP-injected eyes, cortical threshold was also independently correlated with an increase in the extent of retinal gliosis. Conclusions: These data suggest that even when ganglion cell density remains unaffected, glial changes in the retina following degeneration can influence the efficacy of suprachoroidal electrical stimulation. A better understanding of how glial change impacts retinal prosthesis function may help to further the optimization of retinal implants. PMID- 27701634 TI - Myopia and Cognitive Performance: Results From the Gutenberg Health Study. AB - Purpose: To analyze the association between myopia and cognitive performance. Methods: A cohort of the population-based Gutenberg Health Study included 3819 eligible enrollees between 40 and 79 years. We used the Tower of London (TOL) test to assess cognitive performance. Myopia was defined as a spherical equivalent (SE) <= -0.5 diopters (D) via noncycloplegic autorefractometry. We conducted linear mixed models with the SE as the dependent variable and the age, sex, duration of education, and TOL score as covariates. Results: Complete data were available for 3452 participants (90.4%). The mean TOL score was 14.0 +/- 3.9 in the myopes versus 12.9 +/- 4.0 in the nonmyopes (P < 0.001). The mean TOL score increased with the magnitude of myopia: it was 13.9 +/- 3.9 in low (less than -3 D); 14.2 +/- 3.7 in moderate (between -3 and -6 D); and 14.6 +/- 3.5 in high myopia (-6 D and greater; P < 0.001). Both the duration of education and cognitive performance were correlated with the magnitude of myopia (r = -0.21, P < 0.001 and r = -0.15, P < 0.001, respectively). In a linear mixed model, the duration of education significantly predicted myopia (beta = -0.14; t = -7.55; P < 0.001), whereas cognitive performance did not (beta = -0.017; t = -1.26; P = 0.207). There was a significant effect of age on the SE (beta = 0.049; t = 9.89; P < 0.001). Conclusions: When regarded separately, cognitive performance is linked to myopia. However, duration of education, which may be directly related to the risk factors for myopia, is more directly and strongly related to myopia than is cognitive performance. Cognitive ability may be associated with myopia primarily through its impact on level of education. PMID- 27701635 TI - The Role of IRE-XBP1 Pathway in Regulation of Retinal Pigment Epithelium Tight Junctions. AB - Purpose: The retinal pigment epithelium (RPE) tight junctions play a pivotal role in maintaining the homeostatic environment of the neural retina. Herein, we investigated the role of X-box binding protein 1 (XBP1), an endoplasmic reticulum (ER) stress-responsive transcription factor, in regulation of RPE tight junctions. Methods: Human RPE cell line (ARPE-19) and primary primate RPE cells were used for in vitro experiments and RPE-specific XBP1 knockout (KO) mice were used for in vivo study. Endoplasmic reticulum stress was induced by a sublethal dose of thapsigargin or tunicamycin. XBP1 activation was manipulated by IRE inhibitor 4MU8C, which suppresses XBP1 mRNA splicing. The integrity of tight junctions and the involvement of calcium-dependent RhoA/Rho kinase pathway were examined. Results: Induction of ER stress by thapsigargin, but not tunicamycin, disrupted RPE tight junctions in ARPE-19 cells. Inhibition of XBP1 activation by 4MU8C resulted in a remarkable downregulation of tight junction proteins (ZO-1 and occludin) and defects in tight junction formation in the presence or absence of ER stress inducers. Overexpression of active XBP1 partially reversed 4MU8C induced anomalies in tight junctions. Mechanistically, XBP1 inhibition resulted in increased intracellular Ca2+ concentration, upregulation of RhoA expression, redistribution of F-actin, and tight junction damage, which was attenuated by Rho kinase inhibitor Y27632. In vivo, deletion of XBP1 in the RPE resulted in defective RPE tight junctions accompanied by increased VEGF expression. Conclusions: Taken together, these results suggest a protective role of XBP1 in maintaining RPE tight junctions possibly through regulation of calcium-dependent RhoA/Rho kinase signaling and actin cytoskeletal reorganization. PMID- 27701637 TI - Anterior Corneal, Posterior Corneal, and Lenticular Contributions to Ocular Aberrations. AB - Purpose: To determine the corneal surfaces and lens contributions to ocular aberrations. Methods: There were 61 healthy participants with ages ranging from 20 to 55 years and refractions -8.25 diopters (D) to +3.25 D. Anterior and posterior corneal topographies were obtained with an Oculus Pentacam, and ocular aberrations were obtained with an iTrace aberrometer. Raytracing through models of corneas provided total corneal and surface component aberrations for 5-mm diameter pupils. Lenticular contributions were given as differences between ocular and corneal aberrations. Theoretical raytracing investigated influence of object distance on aberrations. Results: Apart from defocus, the highest aberration coefficients were horizontal astigmatism, horizontal coma, and spherical aberration. Most correlations between lenticular and ocular parameters were positive and significant, with compensation of total corneal aberrations by lenticular aberrations for 5/12 coefficients. Anterior corneal aberrations were approximately three times higher than posterior corneal aberrations and usually had opposite signs. Corneal topographic centers were displaced from aberrometer pupil centers by 0.32 +/- 0.19 mm nasally and 0.02 +/- 0.16 mm inferiorly; disregarding corneal decentration relative to pupil center was significant for oblique astigmatism, horizontal coma, and horizontal trefoil. An object at infinity, rather than at the image in the anterior cornea, gave incorrect aberration estimates of the posterior cornea. Conclusions: Corneal and lenticular aberration magnitudes are similar, and aberrations of the anterior corneal surface are approximately three times those of the posterior surface. Corneal decentration relative to pupil center has significant effects on oblique astigmatism, horizontal coma, and horizontal trefoil. When estimating component aberrations, it is important to use correct object/image conjugates and heights at surfaces. PMID- 27701636 TI - Loss of Axin2 Causes Ocular Defects During Mouse Eye Development. AB - Purpose: The scaffold protein Axin2 is an antagonist and universal target of the Wnt/beta-catenin pathway. Disruption of Axin2 may lead to developmental eye defects; however, this has not been examined. The purpose of this study was to investigate the role of Axin2 during ocular and extraocular development in mouse. Methods: Animals heterozygous and homozygous for a Axin2lacZ knock-in allele were analyzed at different developmental stages for reporter expression, morphology as well as for the presence of ocular and extraocular markers using histologic and immunohistochemical techniques. Results: During early eye development, the Axin2lacZ reporter was expressed in the periocular mesenchyme, RPE, and optic stalk. In the developing retina, Axin2lacZ reporter expression was initiated in ganglion cells at late embryonic stages and robustly expressed in subpopulations of amacrine and horizontal cells postnatally. Activation of the Axin2lacZ reporter overlapped with labeling of POU4F1, PAX6, and Calbindin. Germline deletion of Axin2 led to variable ocular phenotypes ranging from normal to severely defective eyes exhibiting microphthalmia, coloboma, lens defects, and expanded ciliary margin. These defects were correlated with abnormal tissue patterning in individual affected tissues, such as the optic fissure margins in the ventral optic cup and in the expanded ciliary margin. Conclusions: Our results reveal a critical role for Axin2 during ocular development, likely by restricting the activity of the Wnt/beta-catenin pathway.

PMID- 27701659 TI - Association Between Therapeutic Hypothermia and Survival After In-Hospital Cardiac Arrest. AB - Importance: Therapeutic hypothermia is used for patients following both out-of hospital and in-hospital cardiac arrest. However, randomized trials on its efficacy for the in-hospital setting do not exist, and comparative effectiveness data are limited. Objective: To evaluate the association between therapeutic hypothermia and survival after in-hospital cardiac arrest. Design, Setting, and Patients: In this cohort study, within the national Get With the Guidelines Resuscitation registry, 26 183 patients successfully resuscitated from an in hospital cardiac arrest between March 1, 2002, and December 31, 2014, and either treated or not treated with hypothermia at 355 US hospitals were identified. Follow-up ended February 4, 2015. Exposure: Induction of therapeutic hypothermia. Main Outcomes and Measures: The primary outcome was survival to hospital discharge. The secondary outcome was favorable neurological survival, defined as a Cerebral Performance Category score of 1 or 2 (ie, without severe neurological disability). Comparisons were performed using a matched propensity score analysis and examined for all cardiac arrests and separately for nonshockable (asystole and pulseless electrical activity) and shockable (ventricular fibrillation and pulseless ventricular tachycardia) cardiac arrests. Results: Overall, 1568 of 26 183 patients with in-hospital cardiac arrest (6.0%) were treated with therapeutic hypothermia; 1524 of these patients (mean [SD] age, 61.6 [16.2] years; 58.5% male) were matched by propensity score to 3714 non-hypothermia-treated patients (mean [SD] age, 62.2 [17.5] years; 57.1% male). After adjustment, therapeutic hypothermia was associated with lower in-hospital survival (27.4% vs 29.2%; relative risk [RR], 0.88 [95% CI, 0.80 to 0.97]; risk difference, -3.6% [95% CI, 6.3% to -0.9%]; P = .01), and this association was similar (interaction P = .74) for nonshockable cardiac arrest rhythms (22.2% vs 24.5%; RR, 0.87 [95% CI, 0.76 to 0.99]; risk difference, -3.2% [95% CI, -6.2% to -0.3%]) and shockable cardiac arrest rhythms (41.3% vs 44.1%; RR, 0.90 [95% CI, 0.77 to 1.05]; risk difference, -4.6% [95% CI, -10.9% to 1.7%]). Therapeutic hypothermia was also associated with lower rates of favorable neurological survival for the overall cohort (hypothermia-treated group, 17.0% [246 of 1443 patients]; non-hypothermia-treated group, 20.5% [725 of 3529 patients]; RR, 0.79 [95% CI, 0.69 to 0.90]; risk difference, -4.4% [95% CI, -6.8% to -2.0%]; P < .001) and for both rhythm types (interaction P = .88). Conclusions and Relevance: Among patients with in-hospital cardiac arrest, use of therapeutic hypothermia compared with usual care was associated with a lower likelihood of survival to hospital discharge and a lower likelihood of favorable neurological survival. These observational findings warrant a randomized clinical trial to assess efficacy of therapeutic hypothermia for in-hospital cardiac arrest. PMID- 27701661 TI - OnabotulinumtoxinA vs Sacral Neuromodulation on Refractory Urgency Urinary Incontinence in Women: A Randomized Clinical Trial. AB - Importance: Women with refractory urgency urinary incontinence are treated with sacral neuromodulation and onabotulinumtoxinA with limited comparative information. Objective: To assess whether onabotulinumtoxinA is superior to sacral neuromodulation in controlling refractory episodes of urgency urinary incontinence. Design, Setting, and Participants: Multicenter open-label randomized trial (February 2012-January 2015) at 9 US medical centers involving 381 women with refractory urgency urinary incontinence. Interventions: Cystoscopic intradetrusor injection of 200 U of onabotulinumtoxinA (n = 192) or sacral neuromodulation (n = 189). Main Outcomes and Measures: Primary outcome, change from baseline mean number of daily urgency urinary incontinence episodes over 6 months, was measured with monthly 3-day diaries. Secondary outcomes included change from baseline in urinary symptom scores in the Overactive Bladder Questionnaire Short Form (SF); range, 0-100, higher scores indicating worse symptoms; Overactive Bladder Satisfaction questionnaire; range, 0-100; includes 5 subscales, higher scores indicating better satisfaction; and adverse events. Results: Of the 364 women (mean [SD] age, 63.0 [11.6] years) in the intention-to treat population, 190 women in the onabotulinumtoxinA group had a greater reduction in 6-month mean number of episodes of urgency incontinence per day than did the 174 in the sacral neuromodulation group (-3.9 vs -3.3 episodes per day; mean difference, 0.63; 95% CI, 0.13 to 1.14; P = .01). Participants treated with onabotulinumtoxinA showed greater improvement in the Overactive Bladder Questionnaire SF for symptom bother (-46.7 vs -38.6; mean difference, 8.1; 95% CI, 3.0 to 13.3; P = .002); treatment satisfaction (67.7 vs 59.8; mean difference, 7.8; 95% CI, 1.6 to 14.1; P = .01) and treatment endorsement (78.1 vs 67.6; mean difference; 10.4, 95% CI, 4.3 to 16.5; P < .001) than treatment with sacral neuromodulation. There were no differences in convenience (67.6 vs 70.2; mean difference, -2.5; 95% CI, -8.1 to 3.0; P = .36), adverse effects (88.4 vs 85.1; mean difference, 3.3; 95% CI, -1.9 to 8.5; P = .22), and treatment preference (92.% vs 89%; risk difference, -3%; 95% CI, -16% to 10%; P = .49). Urinary tract infections were more frequent in the onabotulinumtoxinA group (35% vs 11%; risk difference, -23%; 95% CI, -33% to -13%; P < .001). The need for self catheterization was 8% and 2% at 1 and 6 months in the onabotulinumtoxinA group. Neuromodulation device revisions and removals occurred in 3%. Conclusions and Relevance: Among women with refractory urgency urinary incontinence, treatment with onabotulinumtoxinA compared with sacral neuromodulation resulted in a small daily improvement in episodes that although statistically significant is of uncertain clinical importance. In addition, it resulted in a higher risk of urinary tract infections and need for transient self-catheterizations. PMID- 27701662 TI - Treatments for Nausea and Vomiting During Pregnancy. PMID- 27701664 TI - The Quick Physical Exam. PMID- 27701660 TI - Association Between Low-Density Lipoprotein Cholesterol-Lowering Genetic Variants and Risk of Type 2 Diabetes: A Meta-analysis. AB - Importance: Low-density lipoprotein cholesterol (LDL-C)-lowering alleles in or near NPC1L1 or HMGCR, encoding the respective molecular targets of ezetimibe and statins, have previously been used as proxies to study the efficacy of these lipid-lowering drugs. Alleles near HMGCR are associated with a higher risk of type 2 diabetes, similar to the increased incidence of new-onset diabetes associated with statin treatment in randomized clinical trials. It is unknown whether alleles near NPC1L1 are associated with the risk of type 2 diabetes. Objective: To investigate whether LDL-C-lowering alleles in or near NPC1L1 and other genes encoding current or prospective molecular targets of lipid-lowering therapy (ie, HMGCR, PCSK9, ABCG5/G8, LDLR) are associated with the risk of type 2 diabetes. Design, Setting, and Participants: The associations with type 2 diabetes and coronary artery disease of LDL-C-lowering genetic variants were investigated in meta-analyses of genetic association studies. Meta-analyses included 50 775 individuals with type 2 diabetes and 270 269 controls and 60 801 individuals with coronary artery disease and 123 504 controls. Data collection took place in Europe and the United States between 1991 and 2016. Exposures: Low density lipoprotein cholesterol-lowering alleles in or near NPC1L1, HMGCR, PCSK9, ABCG5/G8, and LDLR. Main Outcomes and Measures: Odds ratios (ORs) for type 2 diabetes and coronary artery disease. Results: Low-density lipoprotein cholesterol-lowering genetic variants at NPC1L1 were inversely associated with coronary artery disease (OR for a genetically predicted 1-mmol/L [38.7-mg/dL] reduction in LDL-C of 0.61 [95% CI, 0.42-0.88]; P = .008) and directly associated with type 2 diabetes (OR for a genetically predicted 1-mmol/L reduction in LDL-C of 2.42 [95% CI, 1.70-3.43]; P < .001). For PCSK9 genetic variants, the OR for type 2 diabetes per 1-mmol/L genetically predicted reduction in LDL-C was 1.19 (95% CI, 1.02-1.38; P = .03). For a given reduction in LDL-C, genetic variants were associated with a similar reduction in coronary artery disease risk (I2 = 0% for heterogeneity in genetic associations; P = .93). However, associations with type 2 diabetes were heterogeneous (I2 = 77.2%; P = .002), indicating gene specific associations with metabolic risk of LDL-C-lowering alleles. Conclusions and Relevance: In this meta-analysis, exposure to LDL-C-lowering genetic variants in or near NPC1L1 and other genes was associated with a higher risk of type 2 diabetes. These data provide insights into potential adverse effects of LDL-C lowering therapy. PMID- 27701665 TI - Treatments for Hyperemesis Gravidarum and Nausea and Vomiting in Pregnancy: A Systematic Review. AB - Importance: Nausea and vomiting affects approximately 85% of pregnant women. The most severe form, hyperemesis gravidarum, affects up to 3% of women and can have significant adverse physical and psychological sequelae. Objective: To summarize current evidence on effective treatments for nausea and vomiting in pregnancy and hyperemesis gravidarum. Evidence Review: Databases were searched to June 8, 2016. Relevant websites and bibliographies were also searched. Titles and abstracts were assessed independently by 2 reviewers. Results were narratively synthesized; planned meta-analysis was not possible because of heterogeneity and incomplete reporting of findings. Findings: Seventy-eight studies (n = 8930 participants) were included: 67 randomized clinical trials (RCTs) and 11 nonrandomized studies. Evidence from 35 RCTs at low risk of bias indicated that ginger, vitamin B6, antihistamines, metoclopramide (for mild symptoms), pyridoxine-doxylamine, and ondansetron (for moderate symptoms) were associated with improved symptoms compared with placebo. One RCT (n = 86) reported greater improvements in moderate symptoms following psychotherapy (change in Rhodes score [range, 0 {no symptoms} to 40 {worst possible symptoms}], 18.76 [SD, 5.48] to 7.06 [SD, 5.79] for intervention vs 19.18 [SD, 5.63] to 12.81 [SD, 6.88] for comparator [P < .001]). For moderate-severe symptoms, 1 RCT (n = 60) suggested that pyridoxine-doxylamine combination taken preemptively reduced risk of recurrence of moderate-severe symptoms compared with treatment once symptoms begin (15.4% vs 39.1% [P < .04]). One RCT (n = 83) found that ondansetron was associated with lower nausea scores on day 4 than metoclopramide (mean visual analog scale [VAS] score, 4.1 [SD, 2.9] for ondansetron vs 5.7 [SD, 2.3] for metoclopramide [P = .023]) but not episodes of emesis (5.0 [SD, 3.1] vs 3.3 [SD, 3], respectively [P = .013]). Although there was no difference in trend in nausea scores over the 14-day study period, trend in vomiting scores was better in the ondansetron group (P = .042). One RCT (n = 159) found no difference between metoclopramide and promethazine after 24 hours (episodes of vomiting, 1 [IQR, 0-5] for metoclopramide vs 2 [IQR, 0-3] for promethazine [P = .81], VAS [0-10 scale] for nausea, 2 [IQR, 1-5] vs 2 [IQR, 1 4], respectively [P = .99]). Three RCTs compared corticosteroids with placebo or promethazine or metoclopramide in women with severe symptoms. Improvements were seen in all corticosteroid groups, but only a significant difference between corticosteroids vs metoclopramide was reported (emesis reduction, 40.9% vs 16.5% at day 2; 71.6% vs 51.2% at day 3; 95.8% vs 76.6% at day 7 [n = 40, P < .001]). For other interventions, evidence was limited. Conclusions and Relevance: For mild symptoms of nausea and emesis of pregnancy, ginger, pyridoxine, antihistamines, and metoclopramide were associated with greater benefit than placebo. For moderate symptoms, pyridoxine-doxylamine, promethazine, and metoclopramide were associated with greater benefit than placebo. Ondansetron was associated with improvement for a range of symptom severity. Corticosteroids may be associated with benefit in severe cases. Overall the quality of evidence was low.

AB - Skin dendritic cells of patients with atopic dermatitis (AD) are well characterized, but less is known about their peripheral blood precursors. The aim of this study was to investigate the phenotypic features and chemokine production of myeloid pre-dendritic cells of patients with AD ex vivo and after stimulation with Staphylococcus enterotoxin B and thymic stromal lymphopoietin, representing an AD-like microenvironment. The expression of cell surface markers was measured by flow cytometry, while chemokine production was monitored with chemokine antibody array and confirmed by enzyme-linked immunoassays. AD pre-dendritic cells expressed higher levels of Fc?RI and the maturation and activation markers tended to be altered. They produced both AD (CCL17/18/22) and maturation-related (CCL3/4/5) chemokines at higher level than controls. The production of CCL3/4 and CCL18 were significantly higher even without AD-specific stimulation, while the production of CCL17 and CCL22 were significantly higher only after stimulation. These results indicate that circulating AD pre-dendritic cells are premature and bear atopic characteristics even without tissue-specific stimulation, suggesting that their development is not only influenced by the skin microenvironment, but even earlier by the local milieu in the blood. PMID- 27701669 TI - Assessing the Concordance of Actinic Keratosis Counts on Digital Photographs with Clinical Examination in Organ Transplant Recipients. AB - Actinic keratoses (AKs) are common lesions that are usually diagnosed clinically. We sought to examine the accuracy of AK counts on digital photographs when compared with clinical examination counts. Skin sites of renal transplant recipients were examined clinically and on digital photographs by independent dermatologically-trained examiners. Specificity, sensitivity and Kendall's tau-b correlation coefficient were calculated based on exact photographic AK counts as well as counts with +/- 1 AK tolerance. When 138 skin sites with 305 clinical AK counts were examined for total count +/- 1 AK, the sensitivity and specificity of photography was 95% and 100%, respectively. There was significant positive correlation between AK counts on photographs and clinical examination (Tb = 0.537) and correlation was even higher for total count +/- 1 AK (Tb = 0.758). The results show moderate to strong concordance between AK counts on digital photographs and on clinical examination. PMID- 27701670 TI - Annular Eruptive Pseudoangiomatosis and Adenovirus Infection: A Novel Clinical Variant of Paraviral Exanthems and a Novel Virus Association. AB - Eruptive pseudoangiomatosis is a distinct exanthem thought to be caused by viruses. The usual rash configu-ration is erythematous papules and macules. An association with echovirus infection has been reported. We present here one adult and one child with this exanthem, supported by clinical, histopathological, and immunohistochemical findings. Both patients presented with prodromal symptoms, widespread angioma-like macules in annular configuration, blanchable telangiectasia, followed by spontaneous remission in 6-8 weeks. Lesional histopathology of the adult patient revealed dilated dermal blood vessels and lymphohistiocytic infiltrates predominated by CD4+ lymphocytes with a 5:1 ratio of CD4:CD8 lymphocytes. No B cells or CD56+ natural killer cells were found. Serology of both patients revealed evidence of active infections by adenoviruses, and a range of other viruses were excluded. We believe that these 2 patients manifested annular eruptive pseudoangio-matosis, a novel variant of the rash with a probable adenovirus association that has not yet been reported.

AB - Survey of early alcohol treatment preferences shows higher confidence in face to face meetings Adult men and women (n = 307), working and living in the area of south west Sweden, answered a web based questionnaire where they graded treatment and caregiver preferences while imagining themselves developing an alcohol problem. Alcohol consumption was measured using AUDIT-C. Face-to-face delivered treatment was preferred over telephone or internet based advice. About 53 percent of the men and women considered treatment given by primary health as poor. Only 7,6 percent would prefer help from a health care centre if they were having alcohol problems. Shame and stigma were considered the main obstacles for both seeking and getting help. Despite the availability of effective treatments for early alcohol problems, many avoid seeking help for their problem. This also applies to socially established people. It is important that the health care recognizes and identifies people with less serious problems and offer them treatment.

PMID- 27701681 TI - Long-Term Health Outcomes and Health-Related Quality of Life in Adolescents from a Cohort of Extremely Premature Infants Born at Less Than 27 Weeks of Gestation in Northern Germany. AB - Background Little is known about the psychosocial development and health-related quality of life (HRQOL) of extremely preterm infants once they are adolescents. Methods The regional population-based study cohort included 90 extremely premature infants (< 27+0 gestational weeks) born between January 1997 and December 1999 in the German state of Schleswig-Holstein. In addition to a neurological and cognitive Wechsler Intelligence Scale for Children, 4th edition assessment, self- and parent-reported psychological problems (Strengths and Difficulties Questionnaire), and health-related quality of life (KINDLR) were obtained and compared with a general population of 3,737 adolescents using data from a German Health Interview and Examination Survey for Children and Adolescents (KiGGS survey 2003-2006, Robert Koch Institute, Germany). Results Overall, 72 of the 90 surviving adolescents and their families (80.0%) participated in this study (mean age: 15.7 years; range: 14.2-17.2). A total of 22 adolescents (30.6%) did not have any neurosensory or cognitive limitations, whereas 31 adolescents (43.1%) were affected by multiple impairments. Parent reported psychological problems were more common in the study cohort for the total difficulties score (11.3 points [standard deviation, SD: 5.9] vs. 7.7 points [SD: 5.0], p < 0.001) and for three of the five domains (emotional symptoms, hyperactivity-inattention, peer relationship problems) compared with the KiGGS reference population. In contrast, the rate of self-reported "abnormal" psychological problems was similar to the reference population. Parent-reported HRQOL was significantly lower in the study cohort for the total score (-3.7 points, p < 0.05) and for three of six subscales (emotional wellbeing, p < 0.05; self-esteem, p < 0.001, and wellbeing with regard to friends/friendship, p < 0.001). The adolescents themselves reported an HRQOL similar to that of the KiGGS reference population, though they rated their HRQOL higher for wellbeing with regard to families (p < 0.001) and wellbeing with regard to school/all-day function (p < 0.001). Overall, the parent- and self-reported HRQOL results were not associated with maternal education or disability status but were associated with adolescents' psychological problems. Conclusion Concordant with the high rate of functional and cognitive limitations, parents of adolescents who were born extremely prematurely faced more psychological problems in their children and reported a lower HRQOL compared with the KiGGS reference population. The adolescents themselves did not recognize these differences. However, having psychological problems was associated with lower self- and parent-reported HRQOL results. PMID- 27701682 TI - Ghrelin, Ghrelin O-Acyltransferase, and Carbohydrate Metabolism During Pregnancy in Calorie-Restricted Mice. AB - Acylation of ghrelin is mediated by ghrelin O-acyltansferase (GOAT). Exogenous acylated ghrelin (AG) stimulates growth hormone (GH) and food intake. In non pregnant (NP) animals, the GOAT-ghrelin-GH axis prevents hypoglycemia caused by caloric restriction (CR). In humans, maternal malnutrition challenges glucose metabolism, which is a key determinant of fetal health. To clarify the role of AG and GH, we compared effects of CR on the GOAT-ghrelin-GH axis in pregnant (P) and NP mice. C57BL/6 wild type (WT) and GOAT knock-out (KO) P and NP mice were freely fed (FF) or subjected to 50% CR for one week. CR was started in P mice on Day 10.5 after conception. We measured body composition, blood glucose, plasma ghrelin and GH, stomach, hypothalamus and pituitary GOAT and ghrelin expression, and liver glycogen content and Pck1 expression. GOAT and AG were undetectable in KO. In NP mice, CR did not affect blood glucose (-1.3 mmol/l, p>0.05) in WT but was lowered (-1.8 mmol/l, p<0.0001) in KO. GH and Pck1 mRNA expression increased in WT but not in KO. In P mice, CR markedly lowered glucose (-2.7 mmol/l; p<0.0001) in WT and caused fatal hypoglycemia in KO, despite similarly elevated GH in WT and KO mice. KO animals are more prone to hypoglycemia than WT. GH, which is high in P animals, does not prevent hypoglycemia caused by CR during pregnancy. Our data suggest a specific role of AG in the regulation of gluconeogenesis to maintain euglycemia during pregnancy when energy availability is limited. PMID- 27701683 TI - Crocus sativus L. versus Citalopram in the Treatment of Major Depressive Disorder with Anxious Distress: A Double-Blind, Controlled Clinical Trial. AB - Introduction: Saffron (Crocus sativus L.) has demonstrated antidepressant effects in clinical studies and extensive anxiolytic effects in experimental animal models. Methods: 66 patients with major depressive disorder accompanied by anxious distress were randomly assigned to receive either saffron (30 mg/day) or citalopram (40 mg/day) for 6 weeks. Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) were used to assess treatment effect during the trial. Results: 60 participants finished the study. Patients who received either saffron or citalopram showed significant improvement in scores of the Hamilton Rating Scale for Depression (P-value<0.001 in both groups) and Hamilton Rating Scale for Anxiety (P-value<0.001 in both groups). Comparison of score changes between the 2 trial arms showed no significant difference (P value=0.984). Frequency of side effects was not significantly different between the 2 groups. Discussion: The present study indicates saffron as a potential efficacious and tolerable treatment for major depressive disorder with anxious distress. PMID- 27701684 TI - [Science based medicine]. PMID- 27701685 TI - [Testing for thrombophilia in patients with venous thromboembolism - why and whom to test?] AB - Hereditary and acquired thrombophilias are known risk factors for a first venous thromboembolism (VTE). In contrast, the relative risk of VTE recurrence in presence of hereditary thrombophilia seems to be at most moderately elevated. However, thrombophilia still contributes to a greater extent to the absolute risk of VTE recurrence. This is explained by the 20-50-fold increased risk of VTE in a subject after a first VTE when compared to the state without previous VTE. Testing for thrombophilia may therefore be helpful in patients at intermediate risk of recurrence in whom the finding of a "strong" thrombophilia can bring about a decision for long-term anticoagulation.

Recent study results however suggest, that other markers are more reliable predictors of metabolic success. A revision of indication criteria is therefore necessary especially for surgical therapy of type 2 diabetes mellitus. Postoperative management should include screening for postbariatric hypoglycemia and bone density. Furthermore psychologic surveillance is recommended.

PMID- 27701689 TI - [Influenza: Whats new?] AB - The burden of disease of influenza in Germany has been dominated by high rates of complications in elderly patients in years with high circulation of H3N2 viruses after the introduction of the new H1N1 strain in 2009. Human infections with avian influenza viruses occur mostly in China. Due to the potential of reassortment with human strains these cases are monitored closely. The efficacy of neuraminidase inhibitors (NI) has been newly rated. In randomized studies effects on reduction of complications could not be found, although large cohort studies have demonstrated a reduction of mortality in patients treated with vs. without neuraminidase inhibitors.The administration and acceptance of influenza vaccine is low in Germany in general and in risk populations. New vaccines have been introduced with quadrivalent vaccines covering both circulating B-types simultaneously and high dose vaccines for elder patients. PMID- 27701688 TI - [Direct oral anticoagulants (DOAC) in tumor patients]. AB - There is only limited data for the use of direct oral anticoagulants (DOACs) in tumor patients and no data from prospective randomised trials comparing DOACs to the current standard care: low molecular weight heparine (LMWH). Therefore, DOACs must be used with caution and should be restricted to tumor patients with (1) contraindications for LMWH (e.g. HIT II, phobia of syringe) or (2) to the situations of prolonged anticoagulation after initial therapy with LMWH. Cancer associated disorders as well as side effects of chemotherapy as nausea and emesis have to be considered as well as potential substance-specific interactions. Data of future clinical trials in prophylaxis and treatment of venous thrombembolism in tumor patients will help to define the role of DOACs in this special patient cohort.

PMID- 27701693 TI - [Evidence-based physical therapy of rheumatic diseases]. AB - New studies increase the evidence, that different applications of physical therapy are effective. In patients with rheumatoid arthritis (RA) physiotherapy of the hands improve strength, joint mobility and activity without increased risk of pain nor inflammation. A theory-based physiotherapy of the hands shows clinical effectiveness and cost-utility. In patients with spondyloarthritides supervised group exercise training is more effective than home exercise programs. Compared with biologics only combined exercise training and tumour necrosis factor alpha inhibitor therapy improve mobility and disease activity more effectively. Aerobic exercise training reduces fatigue in RA. Working wrist splints and static resting splints improve pain and grip strength. Static resting splints reduce the risk of hand deformities. Local and whole body cryotherapy show short term improvement of pain and inflammatory activity. German S3 guidelines recommend enhanced utilisation of physical therapy as well as coordinated multiprofessional team care and rehabilitation.

AB - Alpha-1-antitrypsin deficiency is a genetic risk factor for the development of chronic obstructive airway disease (COPD) and liver cirrhosis. The disease is widely underdiagnosed. The hallmarks of therapy are smoking cessation, prevention from environmental dust exposure and augmentation therapy. Findings from the recently published prospective, placebo-controlled and randomized RAPID trial proved effectiveness of AAT augmentation therapy for slowing progression of emphysema, measured by CT lung density. CT lung density may be more sensitive than forced exspiratory volume in one second (FEV1) or monoxid diffusion capacity (DLCO). The data suggest that higher therapeutic serum AAT levels lead to lower decline in lung density. PMID- 27701694 TI - [Celiac disease]. AB - Celiac disease occurs as a result of a T-cell-dependent immune reaction on gluten peptides. It is a complex genetic disorder that is mediated by an unknown number of genes, of which more than 50 have been identified in whole genome association studies. The genetic component helps identify oligosymptomatic or even subclinical celiacs by screening first-degree relatives and patients suffering from other autoimmune diseases. To offer sensitive as well as specific diagnostics for celiac disease (serology and small intestinal histology) some general rules should be followed including performing diagnostics only when patients are on a gluten-containing diet or after an appropriate re-exposition. Established treatment is currently restricted to a gluten-free diet. However, future treatment options might include endopeptidase-mediated inactivation of gluten peptides, stabilization of the epithelial barrier, tissue-transglutaminase inhibition or vaccination.

AB - History and clinical findings | We report about a 79 year old non-diabetic patient who was admitted to the emergency room with severe hypoglycemia (blood glucose level: 36 mg / dl and Glasgow Coma Scale Score: 3). After the infusion of G40 % her blood glucose level stabilised. The patient reported to have taken 50 mg of Tramadol during the night to treat her headache. Investigations and diagnosis | No other differential diagnosis for hypoglycemia (i.e. diabetes, insulinoma, severe liver or kidney disease) could be established. Therefore, we suspected a tramadol induced hypoglycemia. The mechanisms and the risk factors for this potential side effect remain unclear. The patient showed no abnormality in metabolism (CYP2D6) or membrane transport (OCT1) of tramadol. Treatment and course | No further treatment for hypoglycemic episodes was needed. The patient was discharged after the differential diagnosis and pharmacogenetic testing was completed. Conclusions | Hypoglycemia is a little known adverse effect after tramadol intake, which has only been published in few cases. Tramadol, a weak opioid analgesic classified as step 2 of the WHO cancer pain ladder, is used in moderate pain. Given the continuous rise in tramadol prescription due to better management of chronic pain, further investigation of this issue seems needed as well as an increased awareness amongst physicians. PMID- 27701697 TI - [End-of-life Decisions]. AB - End-of-life decisions in neurology have repeatedly given occasion for controversies. Often these are based on lack of knowledge of the juridical and ethical framework conditions. This review describes the juridical-ethical basis for the implementation and continuation, and for withholding and withdrawal of life-sustaining measures, in particular, the significance of medical indication and patient's will. The different forms of assisted dying ("Sterbehilfe"), namely homicide by request, assisted suicide, palliative symptom relief and treatment withdrawal are characterized. The "Principles of the German Medical Association" in end-of-life situations are illustrated. Specific features of neurological treatment scenarios are discussed such as the preclinical and clinical emergency and acute situation, the decompensation of stable chronic severe brain injury situations, and chronically progressive neurodegenerative diseases. In the latter situations, an early "Advance Care Planning" could contribute to improved end-of life decision-making.

PMID- 27701700 TI - Pursuing Precision Speech-Language Therapy Services for Children with Down Syndrome. AB - The behavioral phenotype of individuals with Down syndrome (DS) offers one avenue for developing speech-language therapy services that are tailored to the individual's characteristics that affect treatment response. Behavioral phenotypes are patterns of behavioral strengths and weaknesses for specific genetic disorders that can help guide the development and implementation of effective interventions. Nonetheless, individual differences within children with DS must be acknowledged and addressed because behavioral phenotypes are probabilistic, not deterministic. Developing precision speech-language therapy services to maximize learning opportunities and outcomes for children with DS calls for increased collaboration among clinicians and researchers to address the needs, challenges, and opportunities on three interconnected themes: (1) moving effective interventions from research to practice, (2) making evidence-based, child-specific treatment intensity decisions, and (3) considering child motivation and temperament characteristics. Increased availability of intervention materials and resources as well as more specific recommendations that acknowledge individual differences could help narrow the research-practice gap. Clear descriptions of disciplined manipulations of treatment intensity components could lead to more effective intervention services. Last, addressing motivation and temperament characteristics, such as the personality-motivation orientation, in children with DS may help maximize learning opportunities. Focused attention and collaboration on these key themes could produce substantial, positive changes for children with DS and their families in the coming decade. PMID- 27701701 TI - A Look into the Crystal Ball for Children Who Are Deaf or Hard of Hearing: Needs, Opportunities, and Challenges. AB - Hearing is essential for the development of speech, spoken language, and listening skills. Children previously went undiagnosed with hearing loss until they were 2.5 or 3 years of age. The auditory deprivation during this critical period of development significantly impacted long-term listening and spoken language outcomes. Due to the advent of universal newborn hearing screening, the average age of diagnosis has dropped to the first few months of life, which sets the stage for outcomes that include children with speech, spoken language, and auditory skill testing in the normal range. However, our work is not finished. The future holds even greater possibilities for children with hearing loss. PMID- 27701702 TI - Playing the Long Game: Considering the Future of Augmentative and Alternative Communication Research and Service. AB - This article examines the growth of aided augmentative and alternative communication (AAC) in providing support to children and youth with significant communication needs. Addressing current trends and offering a discussion of needs and probable future advances is framed around five guiding principles initially introduced by Williams, Krezman, and McNaughton. These include: (1) communication is a basic right and the use of AAC, especially at a young age, can help individuals realize their communicative potential; (2) AAC, like traditional communication, requires it to be fluid with the ability to adapt to different environments and needs; (3) AAC must be individualized and appropriate for each user; (4) AAC must support full participation in society across all ages and interests; and (5) individuals who use AAC have the right to be involved in all aspects of research, development, and intervention. In each of these areas current advances, needs, and future predictions are offered and discussed in terms of researchers' and practitioners' efforts to a continued upward trajectory of research and translational service delivery. PMID- 27701703 TI - Language Disorders in Adolescents: Current Needs and Future Directions. AB - Adolescents with developmental language disorders often do not receive the type of intervention that would improve their ability to speak, listen, read, and write effectively. Part of the problem is that many of these young people show no obvious symptoms of a language disorder, yet they struggle on a daily basis to succeed at school-related tasks that require a sophisticated level of language development. This article discusses some of the challenges these students face and makes suggestions for what could be done to address the issues. These suggestions include continuing the effort to advocate strongly for the rights of adolescents, increasing collaboration between speech-language pathologists and other professionals in the schools, and making changes to training programs in communication sciences and disorders to better prepare future speech-language pathologists to work with adolescents. PMID- 27701705 TI - Childhood Stuttering: Where Are We and Where Are We Going? AB - Remarkable progress has been made over the past two decades in expanding our understanding of the behavioral, peripheral physiologic, and central neurophysiologic bases of stuttering in early childhood. It is clear that stuttering is a neurodevelopmental disorder characterized by atypical development of speech motor planning and execution networks. The speech motor system must interact in complex ways with neural systems mediating language and other cognitive and emotional processes. During the time when stuttering typically appears and follows its path to either recovery or persistence, all of these neurobehavioral systems are undergoing rapid and dramatic developmental changes. We summarize our current understanding of the various developmental trajectories relevant for the understanding of stuttering in early childhood. We also present theoretical and experimental approaches that we believe will be optimal for even more rapid progress toward developing better and more targeted treatment for stuttering in the preschool children who are more likely to persist in stuttering. PMID- 27701704 TI - Nexus to Lexis: Phonological Disorders in Children. AB - Research on phonological disorders in children has conventionally emphasized the speech sound in search of causes, diagnoses, treatments, and prevention of the disorder. This article aims to shift the research focus to the word instead. The motivation comes from advances in psycholinguistics that demonstrate the word is central to the perception, production, and acquisition of phonological information. Three strands of potential study are outlined in evaluation of how words might initiate and boost, but perhaps also, interrupt learning for children with phonological disorders. PMID- 27701706 TI - Pediatric Feeding/Swallowing: Yesterday, Today, and Tomorrow. AB - Speech-language pathologists (SLPs) have played primary roles in the evaluation and management of children with feeding/swallowing disorders for more than five decades. Medical, surgical, and technological advances have improved the survival of young fragile infants and children, many of whom will present with feeding/swallowing problems. Regardless of their underlying etiologies, many of these children are at risk for aspiration-induced lung disease, undernutrition or malnutrition, developmental deficits, and stressful interactions with their caregivers. Unfortunately, our understanding of the physiology/pathophysiology of swallowing and its maturation, the development of standardized and efficacious evaluation and therapy tools, and identification of functional outcomes have not kept pace with our ability to identify children who are at increased risk for dysphagia and the associated sequelae. Given this paucity of evidence to guide practice in pediatrics, clinicians rely upon a combination of data extrapolated from adults with dysphagia, anecdotal reports, and institution-specific guidelines. This article focuses on updates in population demographics and advances in evaluation and treatment over the past decade and identifies future directions that may enable us to meet the needs of the children who are in our care to attain functional outcomes. PMID- 27701707 TI - Children with Specific Language Impairment and Their Families: A Future View of Nature Plus Nurture and New Technologies for Comprehensive Language Intervention Strategies. AB - Future perspectives on children with language impairments are framed from what is known about children with specific language impairment (SLI). A summary of the current state of services is followed by discussion of how these children can be overlooked and misunderstood and consideration of why it is so hard for some children to acquire language when it is effortless for most children. Genetic influences are highlighted, with the suggestion that nature plus nurture should be considered in present as well as future intervention approaches. A nurture perspective highlights the family context of the likelihood of SLI for some of the children. Future models of the causal pathways may provide more specific information to guide gene-treatment decisions, in ways parallel to current personalized medicine approaches. Future treatment options can build on the potential of electronic technologies and social media to provide personalized treatment methods available at a time and place convenient for the person to use as often as desired. The speech-language pathologist could oversee a wide range of treatment options and monitor evidence provided electronically to evaluate progress and plan future treatment steps. Most importantly, future methods can provide lifelong language acquisition activities that maintain the privacy and dignity of persons with language impairment, and in so doing will in turn enhance the effectiveness of speech-language pathologists.

AB - Introduction: Causes of hyponatraemia in older patients are multivariate and in the case of SIADH may often be drug induced. Diagnostic and treatment algorithms are unclear for this important age group. Methods: The author group identified 6 broad themes for consensus and formulated 42 separate consensus statements within these 6 themes. Statements were then circulated to geriatricians, general practitioners and other doctors to test agreement at the European level. Results: 64 responses were evaluated from around Europe. Agreement was achieved in 86% of the statements following amendment and redistribution of 6 of the statements. The survey and its feedback prompted the development of 13 recommendations related to the diagnosis and treatment of hyponatraemia including SIADH. Conclusion: The series of 13 recommendations developed here is intended to increase clarity for clinicians managing older patients with hyponatraemia and SIADH. Surprisingly, despite the lack of clear guidelines or recommendations for this age group consensus levels for the author-based statements were high among the respondents. PMID- 27701712 TI - Downregulation of Notch Signaling Pathway as an Effective Chemosensitizer for Cancer Treatment. AB - Despite remarkable progress in cancer treatment, development of drug resistance is still a big burden to eliminate all tumor cells and a mean cause for tumor recurrence. Recent studies have been revealed the contribution of many signaling pathways in acquisition of resistance to chemotherapy. Because of its potential in maintaining the balance between cell proliferation and apoptosis, Notch signaling pathway has mean relevance to various aspects of cancer biology, from cancer stem cells to tumor immunity to multidrug resistance. Therefore, Notch signaling pathway is an attractive target for cancer therapy because targeting Notch signaling could overcome multi drug resistance (MDR). This article will provide a brief overview of the published evidences in support of Notch targeting in reverting multidrug resistance as a safer and novel approach for the improvement of tumor treatment.

Methods: 104 patients with DPN receiving standard glucose control therapy were randomly assigned into 3 groups: Group-A received PKase treatment, Group-B received PGE1 treatment, and Group-C received only standard glucose control therapy. Michigan neuropathy screening instrument (MNSI) score, neurophysiology examination, and nerve conduction velocity were measured. Results: Standard glucose control therapy significantly reduced hyperglycemia to a similar level in all groups. Questionnaire grading and neurophysiology examination both indicated that no significant difference was found at the end of treatment between Groups A and -B. Except for the ulnar nerve sensory conduction velocity that was significantly improved in Group-B, the remaining nerve conduction velocity (regardless of sensory or motor nerve conduction velocities) was improved to a similar level in Groups -A and -B. Group-A had significantly reduced questionnaire grading and better improvement in motor nerve conduction velocity of the common peroneal nerve, ulnar nerve, and sensory nerve conduction velocity of the sural nerve as compared with Group-C. However, the medical cost of PKase was only 18.9% of that of PGE1 during one course of treatment. Conclusions: PKase has the similar therapeutic efficacy as PGE1 on treatment of DPN in patients with type 2 diabetes. However, the medical cost of PKase is one fifth of that of PGE1. Thus, PKase is a cost-effective drug for treatment of DPN.

AB - Hypothyroidism is associated with the development of non-alcoholic steatohepatitis, but cellular mechanisms have been scarcely analyzed. Thyroid hormones regulate the synthesis and secretion of bile acids that are endogenous ligands of the farnesoid receptor (FXRalpha), which have been involved in the development of non-alcoholic steatohepatitis. However, the relationship between thyroid hormones and FXRalpha expression in the liver is yet unknown. Control (n=6) and methimazole-induced hypothyroid (n=6) female rabbits were used to evaluate the amount of lipids and glycogen, vascularization, hepatocytes proliferation, immune cells infiltration, and expression of FXRalpha. Student-t or Mann-Whitney U tests were carried out to determine significant differences. Hypothyroidism induced steatosis, glycogen loss, fibrosis, and a minor vascularization in the liver. In contrast, hypothyroidism increased the proliferation of hepatocytes and the infiltration of mast cells, but did not modify the number of immune cells into sinusoids. These changes were associated with a minor anti-FXRalpha immunoreactivity of periportal hepatocytes and pericentral immune cells. Our results suggest that hypothyroidism induces a moderate non-alcoholic steatohepatitis, alllowing the hepatic regeneration. The FXRalpha may be involved in the development of non-alcoholic steatohepatitis in hypothyroid subjects. PMID- 27701716 TI - The Influence of Type 1 Diabetes Mellitus on Pulmonary Function and Exercise Capacity - Results from the Study of Health in Pomerania (SHIP). AB - Background: Diabetes mellitus Type 1 (T1DM) is associated with metabolic and microvascular diseases as part of a multi-organ and multi-systemic disorder. The dense network of capillary vessels in the lungs may change during the course of the development of microangiopathy. The connective tissue as well as alveoli may be subjected to non-enzymatic glycosylation of proteins which may in turn affect pulmonary function. Previous studies investigating lung function in patients with type 1 diabetes have only been performed on small numbers of patients. Our study is based on population data of the Study of Health in Pomerania (SHIP). Objective: To investigate the influence of metabolic control on pulmonary system function and to establish a decreased pulmonary system function as a late complication of T1DM in a population based setting. Methods: The study is a case matched study with multiple controls based on participants with T1DM (SHIP-DM-1, n=73) and non-diabetics (SHIP-1, n=292) from the population based study of Pomerania. Data on lung function and exercise performance stratified by age, sex, body mass index and smoking habits in participants with T1DM and without diabetes were matched. Results: Participants with T1DM showed a significantly lower total lung capacity, residual volume and forced vital capacity. The transfer factor for carbon monoxide, the maximum power output and oxygen uptake during exercise were significantly decreased in comparison to the general population without diabetes. Conclusion: The pattern of abnormal pulmonary function as observed in the present study with a reduction in lung volume parameters and reduced oxygen uptake in participants with T1DM suggests a restrictive type of lung disease caused by an intrinsic lung tissue derangement as well as pulmonary microangiopathy. PMID- 27701718 TI - Evaluation of Nanocarrier Targeted Drug Delivery of Capecitabine-PAMAM Dendrimer Complex in a Mice Colorectal Cancer Model. AB - Capecitabine, an effective anticancer drug in colorectal cancer chemotherapy, may create adverse side effects on healthy tissues. In the present study, we first induced colon adenocarcinoma with azoxymethane, a carcinogen agent, and then investigated the potentiality of polyamidoamine (PAMAM) dendrimer to improve capecitabine therapeutic index and decrease its adverse side effects on healthy tissues like liver and bone marrow. Other variables such as nanoparticle concentrations have also been investigated. Drug loading concentration (DLC) and encapsulation efficiency (EE) were calculated for capecitabine/dendrimer complex. Experimental results showed an increase in DLC percentage resulted from elevated capecitabine/dendrimer ratio. Capecitabine/dendrimer complex could reduce tumor size and adverse side effects in comparison with free capecitabine form. PMID- 27701717 TI - Protective Effect of 25Mg-Porphyrin-Fullerene Nanoparticles on Oxygen-Glucose Deprivation/Reperfusion Injury in PC12 Cells. AB - We investigated the effects of 25Mg-Porphyrin-Fullerene nanoparticles, (25MgPMC16) smart ferroporphyrin nanoparticles, on PC12 cells exposed to oxygen glucose deprivation/reperfusion. In order to explore its effect on cells under oxygen-glucose deprivation conditions, the cultures were pretreated with 25MgPMC16 24 hours prior to oxygen-glucose deprivation/reperfusion. To initiate the oxygen-glucose deprivation/reperfusion, the cell culture medium was replaced with a glucose-free medium and the cells were transferred to a humidified incubation chamber in a mixture of 95% N2 and 5% CO2 at 37 degrees C for 30, 60 and 120 min. Cell viability was assessed by MTT assay. Exposure of PC12 cells to 30, 60 and 120 min oxygen-glucose deprivation significantly decreased the cell viability. Pretreatment of the cultures with 25MgPMC16 significantly increased cell viability in a concentration-dependent manner. Pretreatment, the cultures with MK-801 (10 uM), a non-competitive NMDA antagonist, has attenuated the cell death after 30 min oxygen-glucose deprivation. We concluded that 25MgPMC16 could protect PC12 cells against oxygen-glucose deprivation/reperfusion-induced cell injury in a concentration-dependent manner. That could be due to the effect of 25MgPMC16 on ATP synthesis and the antioxidant effects of its components. PMID- 27701719 TI - Neuroprotective Effects of Ellagic Acid in a Rat Model of Parkinson's Disease. AB - Antioxidants have protective effects against free radicals-induced neural damage in Parkinson's disease (PD). We examined the effects of ellagic acid (EA) on locomotion, pallidal local EEG, and its frequency bands' power and also cerebral antioxidant contents in a rat model of PD induced by 6-hydroxidopamine (6-OHDA). 6-OHDA (16 ug/2u l) was injected into the right medial forebrain bundle (MFB) in MFB-lesioned rat's brain. Sham group received vehicle instead of 6-OHDA. PD-model was confirmed by rotational test using apomorphine injection. EA (50 mg/kg/2 ml, by gavages) was administered in PD+EA group. One group of MFB-lesioned rats received pramipexole (PPX; 2 mg/kg/2 ml, by gavages) as a positive control group (PD+PPX group). Motor activity was assessed by stride length, rotarod, and cylinder tests. Pallidal local EEG was recorded in freely moving rats. The levels of malondialdehyde (MDA) besides Glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities were measured in both striatum and hippocampus tissues. MFB lesion caused significant reduction of stride-length (P<0.001), bar decent latency (P<0.001) and frequency bands' power of pallidal EEG (P<0.001). Use of 6-OHDA caused a reduction in the GPx (P<0.001) and SOD (P<0.001) activities while increased significantly the levels of MDA (P<0.001) in MFB lesioned rats. EA significantly restored all above parameters. The results show that EA can improve the motor impairments and electrophysiological performance in the MFB-lesioned rats via raising the cerebral antioxidant contents. Therefore, EA can protect the brain against free radicals-induced neural damage and may be beneficial in the treatment of PD. PMID- 27701720 TI - A Comparison of Effectiveness of Parent Behavioral Management Training and Methylphenidate on Reduction of Symptomsof Attention Deficit Hyperactivity Disorder. AB - Attention deficit hyperactivity disorder (ADHD) is one of the most common psychological disorders of childhood. Methylphenidate is highly effective in the treatment of ADHD. This study aimed to determine the effectiveness of combined Parent behavioral management training (PBMT) and medication treatment (Methylphenidate) in reducing ADHD symptoms in 6-12-year-old children, using randomized sampling. A total of 50 children with ADHD were assigned into two groups: an experimental group of PBMT and a control group of medication treatment (Methylphenidate) without other interventions. Conners' Parent Rating Scale (CPRS 48) was employed before and after interventions to determine the effects. Descriptive Statistics method (consisting of Mean and Standard deviation) and Statistical inference method, (including t-test and Levene's Test) were used for data analysis. Findings revealed that the combined behavioral intervention of PBMT and methylphenidate treatment is more effective in reduction of ADHD in children. The difference of means between pre-test and post-test of CPRS in the experimental group was equal to 10.77, and it was equal to 1.88 in the control group. In addition, PBMT was more effective in the case of younger parents (P<0.025). However, parents' education level did not affect the behavioral intervention (P<0.025).The findings suggest that combined intervention of PBMT and methylphenidate is effective in reducing the symptoms of ADHD in children. PMID- 27701721 TI - Deficiency in Mental Rotation of Upper and Lower-Limbs in Patients With Multiple Sclerosis and Its Relation With Cognitive Functions. AB - Mental rotation is a cognitive motor process which was impaired in different neurologic disorders. We investigated whether there were deficits in response pattern, reaction time and response accuracy rate of mental rotation in multiple sclerosis (MS) patients compared to healthy subjects and whether cognitive dysfunctions in MS patients were correlated with mental rotation deficits. Moreover, we showed whether there was a difference between upper and lower-limbs mental rotation in MS patients. Thirty-five MS patients and 25 healthy subjects performed hand mental rotation (HMR) and foot mental rotation (FMR) tasks. Visual information processing speed, spatial learning and memory ability, and visuospatial processing were assessed by Symbol Digit Modalities Test (SDMT), Brief Visuospatial Memory Test-Revised (BVMT-R), and Judgment of Line Orientation Test (JLO) respectively in MS patients. Reaction time for both hand and foot stimuli increased, and response accuracy rate for hand stimuli decreased in MS patients compared to healthy subjects, but response pattern of mental rotation in MS patients persisted. Similar to healthy subjects, MS patients performed upper limbs mental rotation more easily than a lower-limbs mental rotation with more speed and response accuracy rate. Reaction time and response accuracy rate were correlated with the mentioned cognitive functions. MS patients made use of the correct response pattern for problem solving of increasing orientation from upright stimuli. Reaction time and response accuracy rate altered in these patients and this alteration might occur along with impairment in motor planning. Subjects' better responding to hand stimuli was due to more familiarity with hand stimuli. The correlation of mental rotation ability with cognitive functions indicates the possible role of cognitive functions in mental rotation. PMID- 27701722 TI - Cross-Cultural Adaptation, Reliability and Validity Study of the Persian Version of the Clinical COPD Questionnaire. AB - The clinical COPD questionnaire (CCQ) has been developed to measure the health status of COPD patients. The aim of this study was to translate CCQ into the Persian language and assess the validity and reliability of the translated version. We used a forward-backward procedure to translate the questionnaire. In a cross-sectional study 100 COPD patients and 50 healthy subjects over 40 years old were selected to assess the reliability and construct validity of the instrument. The face and content validity were used for the questionnaire validity. Validity was examined in a population of patients with COPD, using the Persian validated version of the St George's Respiratory Questionnaire (PSGRQ). In order to assess the questionnaire's reliability, the Intraclass correlation coefficient (ICC) and Cronbach's alpha were calculated. Test-retest reliability was tested by re-administering the Persian version of the CCQ (PCCQ) after 1 week. Test-retest carry out of data demonstrates that the PCCQ has excellent reliability (ICC for all 3 domains were higher than 0.9). Internal consistency was found by Cronbach's alpha to be 0.96, 0.94, 0.97, and 0.98 for the symptom, mental state, functional state and total scores respectively. In addition, the correlation between the components of PCCQ and PSGRQ showed satisfactory construct validity. Analyzing the data from healthy subjects and patients divulged that the PCCQ has acceptable discriminant validity. In general, the PCCQ had satisfactory reliability and validity for assessing health-related quality of life status of Iranian COPD patients. PMID- 27701723 TI - Annual Report of Drug and Poison Information in Iran From March 2012 to March 2013. AB - Drug and Poison Information Centers (DPICs) have a critical role in the fulfillment of rational drug use programs and provide services to the scientific community with the aim of improving the health and safety of drug use. This was a retrospective study on recorded calls of DPICs in Iran from March 2012 to March 2013. Data consisted of general information; drug and poisoning information, medical history and also the distribution of a number of calls collected by DPICs in Iran. The centers received a total of 171769 calls. Most calls were made by the patients (56.1%) and then the patients' relatives (38%). Also, 67% of the patients were determined as female. The calls mostly were focused on Adverse Drug Reactions (ADR) (15.3%), indications (14.0%) and drug evaluations (11.8%). Anti infective agents, non-steroidal anti-inflammatory drugs (NSAIDs) and vitamins with 9.6%, 7%, and 6.8% frequencies were the highest frequently asked questions, respectively. Based on the results, patients do not receive enough information about their medications, from physicians and pharmacists. The DPICs have an important role to guide the people and provide the accurate drug and poison information and fill the absence of information that is not provided by medical staff. So, based on the important role of these centers, it is worth the Iran DPICs being introduced more to people, and we need more advertising around the country. PMID- 27701724 TI - Clinical Clerkship Education Improves With Implementing a System of Internal Program Evaluation Using Medical Students' Feedbacks. AB - Quality of clinical education for medical students has always been a concern in academic medicine. This concern has increased in today's time-squeeze while faculty members have to fulfill their complementary roles as a teacher, researcher, and practitioner. One of the strategies for program evaluation is obtaining trainees' feedbacks since they are the main customers of educational programs; however, there are debates about the efficacy of student feedback as a reliable source for reforms. We gathered Likert scores on a 16-item questionnaire from 2,771 medical students participating in all clerkship programs in a multidisciplinary teaching hospital. An expert panel consisting of 8 attending physicians established content validity of the questionnaire while a high Cronbach's Alpha (0.93) proved its reliability. Summary reports of these feedbacks were presented to heads of departments, clerkship program directors, and hospital administrators, at the end of each semester. Analysis of variance was used for comparing hospital scores across different time periods and different departments. Significant changes (P<0.001) were observed in mean scores between different semesters (partial eta2=0.090), different departments (partial eta2=0.149) as well as the interaction term between departments and semesters (partial eta2=0.111). A significant improvement in mean clinical education score is noticeable after three semesters from the beginning of the survey. Periodic, systematic trainee's feedback to program directors can lead to an improved educational performance in teaching hospitals. PMID- 27701725 TI - Efficacy of E-Learning via the Website of Tehran University of Medical Sciences for Diagnosing Tooth Discolorations and Treatment Planning by Senior Dental Students. AB - The efficacy of methods like e-learning as a supplement to traditional face-to face instruction needs to be evaluated in dental courses. This study aimed to assess the efficacy of posting case presentations on one of the educational websites of the virtual school of Tehran University of Medical Sciences called "SARMAD" to enhance the ability of senior dental students to diagnose tooth discolorations and offer treatment plans. This experimental study had a pre test/post-test control group design and was conducted on 63 senior dental students. After filling out the primary questionnaire and obtaining a written informed consent, students participated in a pre-test and were then randomly divided into two groups of intervention and control. Fifteen case presentations were posted on the university website (SARMAD) during 6 weeks and discussed. Then, students participated in a post-test. Students' perspectives and their satisfaction with the website were assessed by a questionnaire. For ethical purposes, the same program was also offered to the controls. The post-test score was significantly higher than the pre-test score in the intervention group (P<0.001); but in the control group, the post-test score was only slightly higher than the pre-test score (P=0.128). In the intervention group, 70% stated that they would suggest this method as an efficient educational modality; 93.3% stated that this method would be beneficial as a supplement to conventional education; 16.7% ranked the SARMAD website excellent, 30% ranked it good, 33.3% acceptable, 16.7% moderate and 3.3 poor. It appears that this instructional modality may be efficiently used as a supplement to traditional instruction in undergraduate dental curricula. PMID- 27701726 TI - Effect of Air Pollution in Frequency of Hospitalizations in Asthmatic Children. AB - Asthma is one of the most common diseases in childhood, which has been increased during last decade because of epidemiological pattern changes with climate and industrialization of the communities. There are some controversies on the relationship between air pollution and asthma. Tehran, as the capital of Iran, is one of the densest populations and is one of the most polluted cities in the world. This study was performed to search effects of various air pollutants using GIS-based modeling on the rate of hospitalizations due to asthma in children in Tehran. Information of patients who were admitted with a diagnosis of asthma in a referral pediatric hospital was checked and the total number of admissions in the same age range (2 to 14 years) during a 2-year period (March 2009-March 2011) were calculated. Information about air pollutants including carbon monoxide, nitrogen dioxide, ozone, and sulfur dioxide, obtained from the air quality control center. Days of the year divided into GOOD and NONGOOD days according to the guideline for reporting of the daily air quality index (AQI). Two thousand two hundred nineteen cases enrolled in the study and asthma admission to total admission ratio compared with air pollutants data in admission day (725 days), using nonlinear regression method. Analysis of the data revealed that there is a significant relationship between NONGOOD nitrogen dioxide (P=0.01), ozone (P=0.01), and sulfur dioxide (P=0.04), levels and admission due to asthma in children, but There was no significant relationship between carbon monoxide levels and asthma admission in children. A significant relationship between nitrogen dioxide, ozone and sulfur dioxide concentration in air and admission due to asthma at levels other than GOOD, reveals air pollutants levels can be significantly harmful to children before AQI reaches to hazardous levels. PMID- 27701727 TI - Unusual Ectopic Parathyroid Adenoma: A Case Report. AB - An ectopically placed parathyroid in the mediastinum is a rare cause of persistent or recurrent primary hyperparathyroidism. They are rarely in a huge size. We report a case of a 70-year-old man with a history of total parathyroidectomy and thymectomy presented with a lack of appetite, nausea, and generalized bone pain, polydipsia and a calcium level of 14.4 mg/dl. 99mTc sestamibi scintigraphy with single-photon emission computerized tomography (SPECT) showed a focal zone of radiotracer accumulation in the midline of anterior chest wall (xiphoid level). The mass excised from our patient surgically was 75 grams. This weight and location of the tumor is a very rare finding in parathyroid adenomas. PMID- 27701728 TI - Warfarin-Induced Skin Necrosis in Patients With Low Protein C Levels. AB - Warfarin-induced skin necrosis (WISN) is a rare complication of anticoagulant therapy associated with a high incidence of morbidity and mortality requiring immediate drug cessation. At particular risk are those with various thrombophilic abnormalities, especially when warfarinisation is undertaken rapidly with large loading doses of warfarin. Cutaneous findings include petechiae that progress to ecchymosis and hemorrhagic bullae. With the increasing number of patients anticoagulated as out-patients for thromboprophylaxis, we are concerned that the incidence of skin necrosis may increase. We present a case of WISN with low protein C level. He was a 50-year-old male who came to our department because of acute infarction in irrigation area of the superior cerebellar artery. He had intermittent atrial fibrillation and was started on anticoagulant therapy. After few day of therapy, he developed skin necrosis, and his level of protein C was low. Warfarin-induced skin necrosis is a rare but serious complication that can be prevented by routine screening for protein C, protein S or antithrombin deficiencies or for the presence of antiphospholipid antibodies before beginning warfarin therapy. PMID- 27701729 TI - Optimization of a beta-sheet-cap for long loop closure. AB - Protein loops make up a large portion of the secondary structure in nature. But very little is known concerning loop closure dynamics and the effects of loop composition on fold stability. We have designed a small system with stable beta sheet structures, including features that allow us to probe these questions. Using paired Trp residues that form aromatic clusters on folding, we are able to stabilize two beta-strands connected by varying loop lengths and composition (an example sequence: RWITVTI - loop - KKIRVWE). Using NMR and CD, both fold stability and folding dynamics can be investigated for these systems. With the 16 residue loop peptide (sequence: RWITVTI-(GGGGKK)2 GGGG-KKIRVWE) remaining folded (DeltaGU = 1.6 kJ/mol at 295K). To increase stability and extend the series to longer loops, we added an additional Trp/Trp pair in the loop flanking position. With this addition to the strands, the 16 residue loop (sequence: RWITVRIW (GGGGKK)2 GGGG-WKTIRVWE) supports a remarkably stable beta-sheet (DeltaGU = 6.3 kJ/mol at 295 K, Tm = ~55 degrees C). Given the abundance of loops in binding motifs and between secondary structures, these constructs can be powerful tools for peptide chemists to study loop effects; with the Trp/Trp pair providing spectroscopic probes for assessing both stability and dynamics by NMR.

PMID- 27701731 TI - Treating Trichotillomania (Hair-Pulling Disorder) in a Child. AB - Although cognitive behavioral treatments (CBTs) have been recommended as first line interventions for trichotillomania (hair-pulling disorder [HPD]), research on CBT for young children with HPD is limited. We illustrate the use of family based CBT for HPD in an 8-year-old boy. The client had a 5-year history of chronic HPD and several large bald spots on the crown of his head. Treatment primarily comprised habit reversal training (HRT) and function-based interventions. The child showed significant improvement in HPD severity and impairment after 8 weekly sessions, although complete abstinence was not achieved. The findings underscore the importance of parental involvement in the treatment and show that children as young as 8 years of age can successfully use strategies taught in HRT. PMID- 27701732 TI - Novel DNMT3A germline mutations are associated with inherited Tatton-Brown-Rahman syndrome. AB - Tatton-Brown-Rahman syndrome (TBRS) was recently described in 13 isolated cases with de novo mutations in the DNMT3A gene. This autosomal dominant condition is characterized by tall stature, intellectual disability and a distinctive facial appearance. Here, we report six cases of inherited TBRS caused by novel DNMT3A germline mutations. The affected individuals belong to two sib-ships: four from an Old Order Amish family in America and two from a French Canadian family in Canada. All of them presented with characteristic features of TBRS, including dysmorphic facial features, increased height, intellectual disability, and variable additional features. We performed clinical exome sequencing and identified two mutations in the DNMT3A gene, a c.2312G>A (p.Arg771Gln) missense mutation in the Amish family and a c.2296_2297delAA (p.Lys766Glufs*15) small deletion in the French Canadian family. Parental DNA analysis by Sanger sequencing revealed that the Amish mutation was inherited from the healthy mosaic father. This study reflects the first cases with inherited TBRS and expands the phenotypic spectrum of TBRS. PMID- 27701733 TI - Antigen presentation by B cells guides programing of memory CD4+ T-cell responses to a TLR4-agonist containing vaccine in mice. AB - The contribution of B cells to immunity against many infectious diseases is unquestionably important and well characterized. Here, we sought to determine the role of B cells in the induction of T-helper 1 (TH 1) CD4+ T cells upon vaccination with a tuberculosis (TB) antigen combined with a TLR4 agonist. We used B-cell deficient mice (MUMT-/- ), tetramer-positive CD4+ T cells, markers of memory "precursor" effector cells (MPECs), and T-cell adoptive transfers and demonstrated that the early antigen-specific cytokine-producing TH 1 responses are unaffected in the absence of B cells, however MPEC induction is strongly impaired resulting in a deficiency of the memory TH 1 response in MUMT-/- mice. We further show that antigen-presentation by B cells is necessary for their role in MPEC generation using B-cell adoptive transfers from wt or MHC class II knock out mice into MUMT-/- mice. Our study challenges the view that B-cell deficiency exclusively alters the TH 1 response at memory time-points. Collectively, our results provide new insights on the multifaceted roles of B cells that will have a high impact on vaccine development against several pathogens including those requiring TH 1 cell-mediated immunity. PMID- 27701735 TI - PINK1 in the limelight: multiple functions of an eclectic protein in human health and disease. AB - The gene PINK1 [phosphatase and tensin homologue (PTEN)-induced putative kinase 1] encodes a serine/threonine kinase which was initially linked to the pathogenesis of a familial form of Parkinson's disease. Research on PINK1 has recently unravelled that its multiple functions extend well beyond neuroprotection, implicating this eclectic protein in a growing number of human pathologies, including cancer, diabetes, cardiopulmonary dysfunctions, and inflammation. Extensive studies have identified PINK1 as a crucial player in the mitochondrial quality control pathway, required to label damaged mitochondria and promote their elimination through an autophagic process (mitophagy). Mounting evidence now indicates that PINK1 activities are not restricted solely to mitophagy, and that different subcellular and even sub-mitochondrial pools of PINK1 are involved in distinct signalling cascades to regulate cell metabolism and survival. In this review, we provide a concise overview on the different functions of PINK1 and their potential role in human diseases. Copyright (c) 2016 Pathological Society of Great Britain and Ireland.

AB - Age-related macular degeneration (AMD) is the leading cause of central vision loss worldwide. Loss of retinal pigment epithelium (RPE) is a major pathological hallmark in AMD with or without pathological neovascularization. Although activation of the immune system is implicated in disease progression, pathological pathways remain diverse and unclear. Here, we report an unexpected protective role of a pro-inflammatory cytokine, interleukin-33 (IL-33), in ocular angiogenesis. IL-33 and its receptor (ST2) are expressed constitutively in human and murine retina and choroid. When RPE was activated, IL-33 expression was markedly elevated in vitro. We found that IL-33 regulated tissue remodelling by attenuating wound-healing responses, including reduction in the migration of choroidal fibroblasts and retinal microvascular endothelial cells, and inhibition of collagen gel contraction. In vivo, local administration of recombinant IL-33 inhibited murine choroidal neovascularization (CNV) formation, a surrogate of human neovascular AMD, and this effect was ST2-dependent. Collectively, these data demonstrate IL-33 as a potential immunotherapy and distinguishes pathways for subverting AMD pathology. (c) 2016 The Authors.

AB - Advances in our understanding of the biology of paediatric central nervous system (CNS) tumours have encouraged pathologists to use molecular markers alongside histopathological analysis for disease classification or prognostication and treatment stratification. In this article, we review molecular genetic alterations in paediatric CNS tumours, including those in low-grade and high grade gliomas, ependymomas, and embryonal tumours. Some of these molecular changes with clinicopathological utility have been used for the first time in the most recent edition of the World Health Organization (WHO) classification of CNS tumours to define entities like ependymoma, RELA fusion-positive or diffuse midline glioma, H3 K27M-mutant. The classification of paediatric CNS tumours is entering a new era when histopathologists must work with molecular genetic data and their molecular pathology colleagues to provide an optimal diagnostic evaluation for their patients and clinical colleagues.

AB - Cucumber (Cucumis sativus) is a widely grown cucurbitaceous vegetable that exhibits a relatively high capacity for silicon (Si) accumulation, but the molecular mechanism for silicon uptake remains to be clarified. Here we isolated and characterized CsLsi1, a gene encoding a silicon transporter in cucumber (cv. Mch-4). CsLsi1 shares 55.70 and 90.63% homology with the Lsi1s of a monocot and dicot, rice (Oryza sativa) and pumpkin (Cucurbita moschata), respectively. CsLsi1 was predominantly expressed in the roots, and application of exogenous silicon suppressed its expression. Transient expression in cucumber protoplasts showed that CsLsi1 was localized in the plasma membrane. Heterologous expression in Xenopus laevis oocytes showed that CsLsi1 evidenced influx transport activity for silicon but not urea or glycerol. Expression of cucumber CsLsi1-mGFP under its own promoter showed that CsLsi1 was localized at the distal side of the endodermis and the cortical cells in the root tips as well as in the root hairs near the root tips. Heterologous expression of CsLsi1 in a rice mutant defective in silicon uptake and the over-expression of this gene in cucumber further confirmed the role of CsLsi1 in silicon uptake. Our results suggest that CsLsi1 is a silicon influx transporter in cucumber. The cellular localization of CsLsi1 in cucumber roots is different from that in other plants, implying the possible effect of transporter localization on silicon uptake capability. PMID- 27701739 TI - Assessment of ochratoxin A occurrence in Argentine red wines using a novel sensitive quechers-solid phase extraction approach prior to ultra high performance liquid chromatography-tandem mass spectrometry methodology. AB - BACKGROUND: The assessment of ochratoxin A (OTA) in wine is relevant for food safety and its continuous control allows to reduce the risk of intake. Thus, a novel sensitive QuEChERS-SPE (Quick, Easy, Cheap, Effective, Rugged and Safe - Solid Phase Extraction) pretreatment prior to liquid chromatography coupled to tandem mass spectrometry was developed for the determination of OTA in red wine samples from different grape-growing regions in Argentine. RESULTS: A sensitive methodology was achieved and thus the limits of detection and quantification were 0.02 and 0.05 ug L-1 , respectively. Recoveries ranged from 89.0% to 105.3%. The method was applied to 136 red wine samples (Argentina's flagship varieties: Malbec and Cabernet Sauvignon) from ten grape-growing regions, during vintages 2013-2015. Although all of the samples investigated were contaminated with OTA (concentrations ranged from 0.02 to 0.98 ug L-1 ), the levels detected were lower than the maximum allowable concentration limit of 2.0 ug L-1 established by international regulations. CONCLUSION: The methodology proposed is suitable for reliable OTA analysis in red wines. Similarly, the values obtained from the samples analyzed were in accordance with the current regulations and, as a consequence, preventive actions to reduce this mycotoxin incidence can be undertaken.

AB - OBJECTIVES: Facial nerve schwannomas (FNSs) and vestibular nerve schwannomas (VNSs) may occupy similar locations in the internal auditory canal (IAC). Risk factors for hearing loss in patients with FNS are unknown. Similar to VNSs, we hypothesize that the size and location of FNSs do not correlate with hearing loss. STUDY DESIGN: Retrospective cohort study and otopathology case review. METHODS: A single institution retrospective review of all patients diagnosed with FNS was performed. Demographic data, tumor size and location, severity and type of hearing loss, and facial nerve function were analyzed. Otopathologic review of a case of FNS was also performed. RESULTS: Thirty-three patients with FNS were identified. Mean age was 44 years, and 61% (n = 21) were female. Nine patients had tumors involving the IAC facial nerve, whereas 24 had distal tumors without IAC involvement. Eleven patients (33%) had hearing loss, and 55% of patients with sensorineural hearing loss (SNHL) had tympanic segment tumors without IAC involvement. The presence of SNHL was not associated with IAC tumor location (P = 0.21). Maximal dimensions of FNSs were 3 mm to 42 mm, without correlation between size and SNHL severity (r = -0.017, P = 0.926). Otopathologic review of an untreated 5-mm IAC FNS demonstrated disproportionate spiral ganglion and hair cell loss within the ipsilateral cochlea compared to the contralateral ear. CONCLUSION: Tympanic segment FNS without IAC involvement may result in SNHL. Tumor size is not associated with the presence or severity of SNHL. Otopathologic review suggests degenerative cochlear changes in FNS. Mechanisms for SNHL in schwannomas are likely multifactorial and may be unrelated to cochlear nerve compression.

PMID- 27701740 TI - Emotional Awareness Moderates the Relationship Between Childhood Abuse and Borderline Personality Disorder Symptom Factors. AB - OBJECTIVE: To examine pathways to borderline personality disorder (BPD), focusing on childhood abuse and emotional attention and clarity. METHOD: Among 293 community residents (mean age = 43.1; 53.9% female), measured associations between the BPD symptom factors of disturbed relatedness, affective dysregulation, and behavioral dysregulation and (a) childhood abuse (emotional, physical, and sexual); (b) emotional attention and clarity; and (c) negative affect, using structured interviews, the Schedule for Non-Adaptive and Adaptive Personality-2, the Trait Meta Mood Scale, and the Positive and Negative Affect Scale, respectively. RESULTS: All forms of childhood abuse were associated with BPD symptom factors. Emotional attention and clarity moderated the effects of childhood physical and emotional abuse on behavioral dysregulation and disturbed relatedness. All results held when controlling for negative affect. CONCLUSION: The relations between childhood abuse and BPD are robust. Emotional attention and clarity may help elucidate the links between childhood abuse and BPD. PMID- 27701742 TI - The new Israeli feed safety law: challenges in relation to animal and public health. AB - The Israeli feed safety legislation, which came to prominence in the early 1970s, has undergone a major change from simple feed safety and quality regulations to a more holistic concept of control of feed safety and quality throughout the whole feed production chain, from farm to the end user table. In February 2014, a new law was approved by the Israeli parliament, namely the Control of Animal Feed Law, which is expected to enter into effect in 2017. The law is intended to regulate the production and marketing of animal feed, guaranteeing the safety and quality of animal products throughout the production chain. The responsibility on the implementation of the new feed law was moved from the Plant Protection Inspection Service to the Veterinary Services and Animal Health. In preparation for the law's implementation, we have characterized the various sources and production lines of feed for farm and domestic animals in Israel and assessed the current feed safety challenges in terms of potential hazards or undesirable substances. Moreover, the basic requirements for feed safety laboratories, which are mandatory for analyzing and testing for potential contaminants, are summarized for each of the contaminants discussed.

AB - Recent evidence has suggested that IL-10-producing effector CD8+ T cells play an important role in regulating excessive inflammation during acute viral infections. However, the cellular and molecular cues regulating the development of IL-10-producing effector CD8+ T cells are not completely defined. Here, we show that type I interferons (IFNs) are required for the development of IL-10 producing effector CD8+ T cells during influenza virus infection in mice. We find that type I IFNs can enhance IL-27 production by lung APCs, thereby facilitating IL-10-producing CD8+ T-cell development through a CD8+ T-cell-nonautonomous way. Surprisingly, we also demonstrate that direct type I IFN signaling in CD8+ T cells is required for the maximal generation of IL-10-producing CD8+ T cells. Type I IFN signaling in CD8+ T cells, in cooperation with IL-27 and IL-2 signaling, promotes and sustains the expression of IFN regulatory factor 4 (IRF4) and B-lymphocyte-induced maturation protein-1 (Blimp-1), two transcription factors required for the production of IL-10 by effector CD8+ T cells. Our data reveal a critical role of the innate antiviral effector cytokines in regulating the production of a regulatory cytokine by effector CD8+ T cells during respiratory virus infection.

AB - INTRODUCTION: Ultrasound (US) evaluation of diaphragm thickness and contractility is an effective tool in neurogenic diaphragm dysfunction. There are limited data about the value of this technique in patients with myopathy. METHODS: We performed a retrospective chart review of cases with electromyography (EMG) confirmed myopathy and real-time US evaluation of the diaphragm. Diaphragm thickness and thickening ratio (maximal inspiration/expiration) were measured. Demographic, imaging, pathology, and genetic data were reviewed, and the clinical diagnosis was recorded. RESULTS: There were 19 eligible cases, of which 14 (73.7%) had abnormal US findings. Mean diaphragm thickness was 0.12 cm (SD 0.10), and the mean thickening ratio was 1.29 (SD 0.35). In all cases with abnormal US evaluation, the thickening ratio was abnormal. There were no cases with abnormal thickness alone. CONCLUSIONS: US examination can detect diaphragm dysfunction in myopathy. It is important to measure both the baseline thickness and thickening ratio to maximize sensitivity.

AB - INTRODUCTION: There is a growing need for a robust clinical measure to assess upper limb motor function in spinal muscular atrophy (SMA), as the available scales lack sensitivity at the extremes of the clinical spectrum. We report the development of the Revised Upper Limb Module (RULM), an assessment specifically designed for upper limb function in SMA patients. METHODS: An international panel with specific neuromuscular expertise performed a thorough review of scales currently available to assess upper limb function in SMA. This review facilitated a revision of the existing upper limb function scales to make a more robust clinical scale. RESULTS: Multiple revisions of the scale included statistical analysis and captured clinically relevant changes to fulfill requirements by regulators and advocacy groups. CONCLUSIONS: The resulting RULM scale shows good reliability and validity, making it a suitable tool to assess upper extremity function in the SMA population for multi-center clinical research.

AB - BACKGROUND: The separation of polyphenols from kiwifruit juice is essential for enhancing sensory properties and prevent the browning reaction in juice during processing and storage. RESULTS: The present study investigated the dynamic adsorption and desorption of polyphenols in kiwifruit juice using AB-8 resin. The model obtained could be successfully applied to predict the experimental results of dynamic adsorption capacity (DAC) and dynamic desorption quantity (DDQ). The results showed that dynamic adsorption of polyphenols could be optimised in a juice concentration of 19 degrees Brix, with a feed flow-rate of 1.3 mL min-1 and a feed volume of 7 bed volume (BV). The optimum conditions for dynamic desorption of polyphenols from the AB-8 resin were an ethanol concentration of 43% (v/v), an elute flow-rate of 2.2 mL min-1 and an elute volume of 3 BV. The optimized DAC value was 3.16 g of polyphenols kg-1 resin, whereas that for DDQ was 917.5 g kg-1 , with both values being consistent with the predicted values generated by the regression models. The major polyphenols in the dynamic desorption solution consisted of seven compositions. CONCLUSION: The present study could be scaled-up using a continuous column system for industrial application, thus contributing to the improved flavor and color of kiwifruit juice.

AB - BACKGROUND: Apnoea is a breathing disorder marked by the absence of airflow at the nose or mouth. In children, risk factors include adenotonsillar hypertrophy, obesity, neuromuscular disorders and craniofacial anomalies. The most common treatment for obstructive sleep apnoea syndrome (OSAS) in childhood is adeno tonsillectomy. This approach is limited by its surgical risks, mostly in children with comorbidities and, in some patients, by recurrence that can be associated with craniofacial problems. Oral appliances and functional orthopaedic appliances have been used for patients who have OSAS and craniofacial anomalies because they hold the lower jaw (mandible) forwards which potentially enlarges the upper airway and increases the upper airspace, improving the respiratory function. OBJECTIVES: To assess the effects of oral appliances or functional orthopaedic appliances for obstructive sleep apnoea in children. SEARCH METHODS: We searched the following electronic databases: Cochrane Oral Health's Trials Register (to 7 April 2016); Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 3) in the Cochrane Library (searched 7 April 2016); MEDLINE Ovid (1946 to 7 April 2016); Embase Ovid (1980 to 7 April 2016); LILACS BIREME (from 1982 to 7 April 2016); BBO BIREME (from 1986 to 7 April 2016) and SciELO Web of Science (from 1997 to 7 April 2016). We searched ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform for ongoing trials on 7 April 2016. We placed no restrictions on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: All randomised or quasi-randomised controlled trials comparing all types of oral and functional orthopaedic appliances with placebo or no treatment, in children 15 years old or younger. PRIMARY OUTCOME: reduction of apnoea to less than one episode per hour. SECONDARY OUTCOMES: dental and skeletal relationship, sleep parameters improvement, cognitive and phonoaudiological function, behavioural problems, quality of life, side effects (tolerability) and economic evaluation. DATA COLLECTION AND ANALYSIS: Two review authors screened studies and extracted data independently. Authors were contacted for additional information. We calculated risk ratios with 95% confidence intervals for all important dichotomous outcomes. We assessed the quality of the evidence of included studies using GRADEpro software. MAIN RESULTS: The initial search identified 686 trials. Only one trial, reporting the results from a total of 23 children and comparing an oral appliance to no treatment, was suitable for inclusion in the review. The trial assessed apnoea-hypopnoea, daytime symptoms (sleepiness, irritability, tiredness, school problems, morning headache, thirstiness in the morning, oral breathing and nasal stuffiness) and night-time symptoms (habitual snoring, restless sleep and nightmares measured by questionnaire). Results were inconsistent across outcomes measures and time points. The evidence was considered very low quality. AUTHORS' CONCLUSIONS: There is insufficient evidence to support or refute the effectiveness of oral appliances and functional orthopaedic appliances for the treatment of obstructive sleep apnoea in children. Oral appliances or functional orthopaedic appliances may be considered in specified cases as an auxiliary in the treatment of children who have craniofacial anomalies which are risk factors for apnoea. PMID- 27701748 TI - Effect of high hydrostatic pressure on the polyphenols and antioxidant activity of plantain pulp (Musa paradisiaca AAB). AB - BACKGROUND: The impact of high-pressure processing (HPP) on the polyphenol (PP) content and antioxidant activity (AOX) of plantain pulp was evaluated. Pressures of 400, 500 and 600 MPa were applied to plantain pulp for 90 and 180 s at room temperature (25 degrees C). Polyphenoloxidase activity, extractable (EPP) and non-extractable PP (NEPP) contents, flavonoid content and AOX (FRAP, ABTS*+ ) were evaluated. In addition, PP identification was performed using high performance liquid chromatography. RESULTS: Polyphenoloxidase activity was inhibited after HPP under all of the conditions studied. Increases of 110.80% and 137.40% in EPP content under conditions of 500 MPa/180 s and 600 MPa/90 s were observed with a simultaneous improvement in the AOX with increments of up to 128.71%. The treatment under conditions of 500 MPa/90 s had the highest total PP content, including the highest content of flavonoids (0.22 g ellagic acid equivalents kg-1 dry weight) and the proportion of NEPP that contained hydrolysable PPs (91.12 g gallic acid equivalents kg-1 dry weight with high AOX. The identified PPs included catechin, quercetin, gallic and hydroxybenzoic acids. CONCLUSION: HPP performed at a room temperature can be used for improving the total content of PP compounds in plantain pulp under specific pressure and time conditions.

AB - INTRODUCTION: Health care demand is increasing due to greater longevity of patients with chronic comorbidities. This increasing demand is occurring in a setting of resource scarcity. To address these changes, high-value care initiatives, such as telemedicine, are valuable resource-preservation strategies. This study introduces the Roth score as a telemedicine tool that uses patient counting times to accurately risk-stratify dyspnea severity in terms of hypoxia. HYPOTHESIS: The Roth score has correlation with dyspnea severity. METHODS: This is a prospective, controlled-cohort study. Roth score index is measured by having the patient count from 1 to 30 in their native language, in a single breath, as rapidly as possible. The primary result of the Roth score is the duration of time and the highest number reached. RESULTS: There was a strongly positive correlation between pulse oximetry and both maximal count achieved in 1 breath (r = 0.67; P < 0.001) and counting time (r = 0.59; P < 0.001). For oxygen saturation <95%, the maximal count number area under the curve is 0.828 and counting time area under the curve is 0.764. Counting time >8 seconds had a sensitivity of 78% and specificity of 73% for pulse oximetry <95%. CONCLUSIONS: The Roth score has strong correlation with dyspnea severity as determined by hypoxia. This tool is reproducible, low resource-utilization, and amenable to telemedicine. It is not intended to replace full clinical workup and diagnosis of respiratory distress, but it is useful in risk-stratifying severity of dyspnea that warrants further clinical evaluation. PMID- 27701753 TI - Gamma aminobutyric acid (GABA) receptor agonists for acute stroke. AB - BACKGROUND: Gamma aminobutyric acid (GABA) receptor agonists have been shown to have a neuroprotectant effect in reducing infarct size and improving functional outcome in animal models of cerebrovascular disease. However, the sedative effects of GABA receptor agonists have limited their wider application in people with acute stroke, due to the potential risk of stupor. This is an update of a Cochrane review first published in 2013, and previously updated in 2014. OBJECTIVES: To determine the efficacy and safety of GABA receptor agonists in the treatment of acute stroke. SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (accessed March 2016), the Cochrane Central Register of Controlled Trials (CENTRAL) 2016, Issue 3, part of the Cochrane Library (accessed March 2016), MEDLINE (from 1949 to March 2016), Embase (from 1980 to March 2016), CINAHL (from 1982 to March 2016), AMED (from 1985 to March 2016), and 11 Chinese databases (accessed March 2016). In an effort to identify further published, unpublished, and ongoing trials we searched ongoing trials registers, reference lists, and relevant conference proceedings, and contacted authors and pharmaceutical companies. SELECTION CRITERIA: We included randomized controlled trials (RCTs) investigating GABA receptor agonists versus placebo for people with acute stroke (within 12 hours after stroke onset), with the primary outcomes of efficacy and safety. DATA COLLECTION AND ANALYSIS: Two review authors independently screened the titles and abstracts of identified records, selected studies for inclusion, extracted eligible data, cross-checked the data for accuracy, and assessed the risk of bias. MAIN RESULTS: We included five trials with 3838 participants (3758 analyzed). The methodological quality of the included trials was generally good, with an unclear risk for selection bias only. Four trials (N = 2909) measured death and dependency at three months for chlormethiazole versus placebo; pooled results did not find a significant difference (risk ratio (RR) 1.03, 95% confidence interval (CI) 0.96 to 1.11). One trial (N = 849) measured this outcome for diazepam versus placebo (RR 0.94, 95% CI 0.82 to 1.07). The most frequent adverse events related to chlormethiazole were somnolence (RR 4.56, 95% CI 3.50 to 5.95; two trials; N = 2527) and rhinitis (RR 4.75, 95% CI 2.67 to 8.46; two trials; N = 2527). AUTHORS' CONCLUSIONS: This review provides moderate-quality evidence that fails to support the use of GABA receptor agonists (chlormethiazole or diazepam) for the treatment of people with acute stroke. More well-designed RCTs with large samples of participants with total anterior circulation syndrome are required to determine if there are benefits for this subgroup. Somnolence and rhinitis are frequent adverse events related to chlormethiazole. PMID- 27701752 TI - Immunotherapy for IgM anti-myelin-associated glycoprotein paraprotein-associated peripheral neuropathies. AB - BACKGROUND: Serum monoclonal anti-myelin-associated glycoprotein (anti-MAG) antibodies may be pathogenic in some people with immunoglobulin M (IgM) paraprotein and demyelinating neuropathy. Immunotherapies aimed at reducing the level of these antibodies might be expected to be beneficial. This is an update of a review first published in 2003 and previously updated in 2006 and 2012. OBJECTIVES: To assess the effects of immunotherapy for IgM anti-MAG paraprotein associated demyelinating peripheral neuropathy. SEARCH METHODS: On 1 February 2016 we searched the Cochrane Neuromuscular Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase for randomised controlled trials (RCTs). We also checked trials registers and bibliographies, and contacted authors and experts in the field. SELECTION CRITERIA: We included randomised controlled trials (RCTs) or quasi-RCTs involving participants of any age treated with any type of immunotherapy for anti-MAG antibody-associated demyelinating peripheral neuropathy with monoclonal gammopathy of undetermined significance and of any severity.Our primary outcome measures were numbers of participants improved in disability assessed with either or both of the Neuropathy Impairment Scale (NIS) or the modified Rankin Scale (mRS) at six months after randomisation. Secondary outcome measures were: mean improvement in disability, assessed with either the NIS or the mRS, 12 months after randomisation; change in impairment as measured by improvement in the 10 metre walk time, change in a validated linear disability measure such as the Rasch-built Overall Disability Scale (R-ODS) at six and 12 months after randomisation, change in subjective clinical scores and electrophysiological parameters at six and 12 months after randomisation; change in serum IgM paraprotein concentration or anti-MAG antibody titre at six months after randomisation; and adverse effects of treatments. DATA COLLECTION AND ANALYSIS: We followed standard methodological procedures expected by Cochrane. MAIN RESULTS: We identified eight eligible trials (236 participants), which tested intravenous immunoglobulin (IVIg), interferon alfa-2a, plasma exchange, cyclophosphamide and steroids, and rituximab. Two trials of IVIg (22 and 11 participants, including 20 with antibodies against MAG), had comparable interventions and outcomes, but both were short-term trials. We also included two trials of rituximab with comparable interventions and outcomes.There were very few clinical or statistically significant benefits of the treatments used on the outcomes predefined for this review, but not all the predefined outcomes were used in every included trial and more responsive outcomes are being developed. A well-performed trial of IVIg, which was at low risk of bias, showed a statistical benefit in terms of improvement in mRS at two weeks and 10-metre walk time at four weeks, but these short-term outcomes are of questionable clinical significance. Cyclophosphamide failed to show any benefit in the single trial's primary outcome, and showed a barely significant benefit in the primary outcome specified here, but some toxic adverse events were identified.Two trials of rituximab (80 participants) have been published, one of which (26 participants) was at high risk of bias. In the meta-analysis, although the data are of low quality, rituximab is beneficial in improving disability scales (Inflammatory Neuropathy Cause and Treatment (INCAT) improved at eight to 12 months (risk ratio (RR) 3.51, 95% confidence interval (CI) 1.30 to 9.45; 73 participants)) and significantly more participants improve in the global impression of change score (RR 1.86, 95% CI 1.27 to 2.71; 70 participants). Other measures did not improve significantly, but wide CIs do not preclude some effect. Reported adverse effects of rituximab were few, and mostly minor.There were few serious adverse events in the other trials. AUTHORS' CONCLUSIONS: There is inadequate reliable evidence from trials of immunotherapies in anti-MAG paraproteinaemic neuropathy to form an evidence base supporting any particular immunotherapy treatment. IVIg has a statistically but probably not clinically significant benefit in the short term. The meta-analysis of two trials of rituximab provides, however, low-quality evidence of a benefit from this agent. The conclusions of this meta-analysis await confirmation, as one of the two included studies is of very low quality. We require large well-designed randomised trials of at least 12 months' duration to assess existing or novel therapies, preferably employing unified, consistent, well-designed, responsive, and valid outcome measures.

PMID- 27701751 TI - Fine-tuning vascular fate during endothelial-mesenchymal transition. AB - In the heart and other organs, endothelial-mesenchymal transition (EndMT) has emerged as an important developmental process that involves coordinated migration, differentiation, and proliferation of the endothelium. In multiple disease states including cancer angiogenesis and cardiovascular disease, the processes that regulate EndMT are recapitulated, albeit in an uncoordinated and dysregulated manner. Members of the transforming growth factor beta (TGFbeta) superfamily are well known to impart cellular plasticity during EndMT by the timely activation (or repression) of transcription factors and miRNAs in addition to epigenetic regulation of gene expression. On the other hand, fibroblast growth factors (FGFs) are reported to augment or oppose TGFbeta-driven EndMT in specific contexts. Here, we have synthesized the currently understood roles of TGFbeta and FGF signalling during EndMT and have provided a new, comprehensive paradigm that delineates how an autocrine and paracrine TGFbeta/FGF axis coordinates endothelial cell specification and plasticity. We also provide new guidelines and nomenclature that considers factors such as endothelial cell heterogeneity to better define EndMT across different vascular beds. This perspective should therefore help to clarify why TGFbeta and FGF can both cooperate with or oppose one another during the complex process of EndMT in both health and disease.

AB - OBJECTIVES: To prospectively assess symptoms before and after sialendoscopy assisted salivary duct surgery (SASDS) in patients with symptomatic sialadenitis without sialolithiasis. STUDY DESIGN: Prospective cohort study. METHODS: Patients with chronic obstructive sialadenitis without sialolithiasis (COSWS) completed the Chronic Obstructive Sialadenitis Symptoms (COSS) questionnaire prior to SASDS and 3 months postoperatively. RESULTS: Of 80 consecutive patients in a 20-month period, 20 surveyed patients underwent SASDS for COSWS in 37 symptomatic glands. Major symptom improvement (> 10 COSS score reduction) was reported in 24 of 37 (65%) of all glands, including 14 of 21 (67%) of radioactive iodine (RAI)-induced cases and 10 of 13 (77%) of idiopathic sialadenitis cases. A significant reduction in postoperative mean COSS scores was seen overall (12.6 points, standard deviation [SD] 19.3, P < 0.05 to a post-SASDS mean score of 26.6). However, 19 of 37 (51%) glands demonstrated postoperative COSS scores above 25, denoting persistent disease. Mean COSS score reductions in RAI-induced sialadenitis (12.4 points, SD 22.7, P < 0.05) and idiopathic sialadenitis (16.3 points, SD 13.7, P < 0.005) groups were significant, with post-SASDS COSS mean scores of 30.6 (SD 19.8) and 20.8 (SD 13.8), respectively. Ducts with stenoses treated with dilation or sialodochoplasty showed significant COSS improvements of 21.1 (SD 17.9) and 12.4 points (SD 10.7), respectively (P < 0.05). In a multivariate analysis, both the presence of stenosis and sialodochoplasty were independent predictors of complete or partial resolution (post-COSS score < 25) and major symptom improvement (P < 0.05). CONCLUSION: SASDS provides short-term symptom reduction in patients with COSWS; particularly in RAI-induced and idiopathic sialadenitis, and in duct stenosis amenable to dilation or sialodochoplasty. However, approximately half of the glands did not achieve meaningful symptom resolution. LEVEL OF EVIDENCE: 4 Laryngoscope, 127:1073-1079, 2017.

PMID- 27701758 TI - Prevalence of past-year dental visit among US adults, 1999-2010: comparison of trends and estimates between the Behavioral Risk Factor Surveillance System and three national surveys. AB - OBJECTIVES: To compare estimated prevalence of past-year dental visit (PPYDV) among US adults aged >=18 years from the Behavioral Risk Factor Surveillance System (BRFSS) to estimates from the Medical Expenditure Panel Survey (MEPS), National Health Interview Survey (NHIS), and National Health and Nutrition Examination Survey (NHANES). METHODS: We estimated PPYDV adjusted for covariates (age, race/ethnicity, education level, poverty status, edentulism) using BRFSS, MEPS, and NHIS 1999-2010, and NHANES 1999-2004. We tested trend in overall PPYDV for BRFSS, MEPS, and NHIS from 1999-2010. For 2002 and 2010, we calculated absolute differences (AD) and 95% confidence intervals (CI) in PPYDV between BRFSS and each of the other surveys overall and among subpopulations defined by covariates. We pooled NHANES 1999-2004 data for comparison with BRFSS 2002. RESULTS: From 1999 to 2010, BRFSS (68.5% vs. 67.5%), MEPS (43.5% vs. 39.7%), and NHIS (63.3% vs. 59.7%) showed small but significant decreases in overall PPYDV. In 2002, estimates for overall PPYDV were highest for BRFSS (70.0%) and lowest for MEPS (43.9%) with estimates for NHIS (61.5%) and NHANES (1999-2004: 58.1%) in between; the largest AD (26.2%, 95% CI: 25.0%-27.3%) was between BRFSS and MEPS. ADs were consistent in 2002 and 2010, overall and by covariates, except among edentate persons, where PPYDV estimates from BRFSS and NHIS were similar. CONCLUSIONS: Estimates of PPYDV from BRFSS were notably higher than estimates from MEPS, NHIS, or NHANES except among the edentate. Trends in PPYDV over time, however, were consistent across all surveys. PMID- 27701759 TI - Spurious reticulocyte profiles in dogs with large form babesiosis: a retrospective study. AB - BACKGROUND: Erroneously high reticulocyte counts (pseudoreticulocytosis) have been reported in dogs with leukemia. Pseudoreticulocytosis and an abnormal reticulocyte profile were observed in a dog with large form babesiosis presented at our institution. OBJECTIVES: The aims of this retrospective study were to determine if dogs with babesiosis and other dogs had abnormal reticulocyte profiles, and to correlate these profiles with the primary diagnosis. METHODS: All canine CBCs obtained with the Sysmex XT-2000iV or Procyte DX were reviewed. Cases of large form babesiosis were identified and their reticulocyte dot plots were analyzed. Dogs with abnormal reticulocyte profiles but without microscopically apparent intraerythrocytic Babesia piroplasms were identified. The reticulocyte profiles and fluorescence ratios of dogs with and without babesiosis were compared. RESULTS: Twenty of 92 dogs with babesiosis had abnormal reticulocyte profiles, including 8 with a separation between the reticulocyte and mature RBC plots or a continuum of reticulocytes from the RBC plot but with a higher density of dots in the middle of the "comet tail" than in the left quarter of the dot plot. Thirteen of 6980 dogs without Babesia on the blood smear had abnormal reticulocyte profiles, including 3 with leukemia. The medium fluorescence reticulocyte ratios tended to be higher in dogs with babesiosis and abnormal dot plots than in other dogs, whereas the high-fluorescence ratio was higher in one dog with leukemia. CONCLUSION: Abnormal reticulocyte dot plots and atypical reticulocyte fluorescence ratios may occur in dogs with babesiosis and alert clinical pathologists to consider this diagnosis. PMID- 27701761 TI - Transudate or exudate: can lactate dehydrogenase activity in canine and feline effusions help to differentiate between the 2? AB - BACKGROUND: Lactate dehydrogenase (LDH) activity is often measured in human effusions to help in differentiating between transudates and exudates. Few studies have been performed using effusion samples from animals. OBJECTIVES: The purpose of the study was to determine whether LDH can be used to differentiate between transudative and exudative effusions in dogs and cats (including postmortem samples), and whether there is a difference between different laboratory methods of LDH measurement. METHODS: Lactate dehydrogenase activity was measured in canine and feline effusions that were submitted to the Murdoch University Veterinary Hospital Clinical Pathology Laboratory over approximately 12 months using 2 wet and one dry chemistry methods, including 10 effusions collected postmortem. Results were compared to classification using traditional methods for effusion types. RESULTS: Lactate dehydrogenase activity was significantly higher in exudates than in transudates, significantly different depending on the method of measurement, and significantly higher in all effusions collected postmortem. An LDH effusion:serum ratio of < 0.5 was associated with transudates. There was no significant difference between samples collected into EDTA or plain serum tubes, in frozen and thawed samples, or after storage at 4 degrees C for 3-7 days. CONCLUSIONS: Measurement of LDH activity may be useful in helping to differentiate between transudates and exudates in cats and dogs. The method of measurement must be known and kept consistent if cutoff values are to be used. The LDH activity was increased in all effusions collected from animals after death, potentially invalidating its use postmortem. PMID- 27701760 TI - Chronic granulomatous disease: Clinical, functional, molecular, and genetic studies. The Israeli experience with 84 patients. AB - Chronic granulomatous disease (CGD) is an innate immunodeficiency with a genetic defect of the nicotinamide adenosine dinucleotide phosphate, reduced, oxidase components. This leads to decreased reactive oxygen species (ROS) production, which renders patients susceptible to life-threatening infections. Over the course of 30 years, we diagnosed CGD in 84 patients from 61 families using functional, molecular, and genetic studies. The incidence of CGD in Israel is 1.05 per 100,000 live-births in the Jewish population and 1.49 in the Israeli Arab population. We diagnosed 52 patients (62%) with autosomal recessive inheritance (AR-CGD) and 32 (38%) with X-linked recessive inheritance (XLR-CGD). Consanguinity was detected in 64% of AR-CGD families (14% in Jews and 50% in Israeli Arabs). We found 36 different mutations (23 in XLR-CGD and 13 in AR-CGD patients), 15 of which were new. The clinical spectrum of CGD varied from mild to severe disease in both XLR and AR forms, although the AR subtype is generally milder. Further, residual ROS production correlated with milder clinical expression, better prognosis and improved overall survival. Patients with recurrent pyogenic infections developed fibrosis and hyperinflammatory states with granuloma formation. The management of CGD has progressed substantially in recent years, evolving from a fatal disease of early childhood to one of long term survival. Our present cohort displays an encouraging 81% overall long term survival. Early hematopoietic stem cell transplantation is advisable before tissue damage is irreversible. Successful transplantation was performed in 18/21 patients. Therapeutic gene modification could become an alternative cure for CGD. Am. J. Hematol. 92:28-36, 2017. (c) 2016 Wiley Periodicals, Inc.

AB - AIMS: Urgency urinary incontinence (UUI), and the symptoms of overactive bladder (OAB) have a negative impact on female sexual function. The aim of this study was to investigate the effect of intravesical onabotulinumtoxinA (Botox) injection on sexual function in women with OAB, using the multi domain Female Sexual Function Index (FSFI) questionnaire. METHODS: Sixty-eight sexually active women with idiopathic OAB with at least one episode of UUI and >=8 micturitions per 24 h were recruited. Patients completed the FSFI questionnaire before and 12 weeks after treatment with intravesical onabotulinumtoxinA injections. Baseline scores were compared with a control group of age-matched healthy women. RESULTS: Fifty six women completed the study. At baseline OAB patients reported decreased quality of sexual function in all domains measured with FSFI, in comparison to healthy women (median 21.8 vs. 26.3, P < 0.001). Over 90% of participants reported clinically relevant improvements in sexual function, with statistically significant changes in mean scores in all six domains. CONCLUSIONS: Intravesical Botox injections provide improvement in sexual function in women with OAB. Neurourol. Urodynam. 9999:XX-XX, 2016. (c) 2016 Wiley Periodicals, Inc.

AB - AIMS: Currently pulmonary carcinoids are separated into typical and atypical based on mitotic count and presence of necrosis, according to the World Health Organization. At variance with gastroenteropancreatic neuroendocrine tumours, which are graded based on mitotic count and Ki-67 proliferative index, the use of Ki-67 for grading pulmonary carcinoids is still under debate. METHODS AND RESULTS: In this study we evaluated the prognostic impact of Ki-67 assessment in a multicentre cohort of 201 carcinoids [147 typical carcinoids (TCs) and 54 atypical carcinoids (ACs)] using manual analysis (2000 cells counted) and digital image analysis (in-house Leica Qwin program; >=4500 cells counted). The Ki-67 proliferative index was correlated with overall survival by means of univariate analysis and in comparison to clinical data by means of multivariable analysis. The Ki-67 index was significantly higher in ACs than in TCs for both counting methods (P <= 2.7e-5 ). In addition, using cut-offs of 2.5% and 4% (manual counting) or 1% and 5% (digital analysis), the highest differences in overall survival were observed (P <= 0.0067). Nevertheless, histopathological classification into TCs and ACs showed an equally strong association with disease outcome, although Ki-67 had some additive value within TCs. Ki-67 index was not an independent predictor of survival in multivariable analysis. CONCLUSIONS: Our study demonstrates that, although Ki-67 is a strong prognostic factor for pulmonary carcinoids, its usefulness in addition to histopathology in prediction of prognosis is limited. None the less, it may have additional value, especially in cases that are difficult to classify, in combination with histopathology and other molecular markers. PMID- 27701764 TI - Modeling and minimizing CAPRI round 30 symmetrical protein complexes from CASP-11 structural models. AB - Many of the modeling targets in the blind CASP-11/CAPRI-30 experiment were protein homo-dimers and homo-tetramers. Here, we perform a retrospective docking based analysis of the perfectly symmetrical CAPRI Round 30 targets whose crystal structures have been published. Starting from the CASP "stage-2" fold prediction models, we show that using our recently developed "SAM" polar Fourier symmetry docking algorithm combined with NAMD energy minimization often gives acceptable or better 3D models of the target complexes. We also use SAM to analyze the overall quality of all CASP structural models for the selected targets from a docking-based perspective. We demonstrate that docking only CASP "center" structures for the selected targets provides a fruitful and economical docking strategy. Furthermore, our results show that many of the CASP models are dockable in the sense that they can lead to acceptable or better models of symmetrical complexes. Even though SAM is very fast, using docking and NAMD energy minimization to pull out acceptable docking models from a large ensemble of docked CASP models is computationally expensive. Nonetheless, thanks to our SAM docking algorithm, we expect that applying our docking protocol on a modern computer cluster will give us the ability to routinely model 3D structures of symmetrical protein complexes from CASP-quality models.

PMID- 27701765 TI - Diagnostic accuracy of Wright-Giemsa and rhodanine stain protocols for detection and semi-quantitative grading of copper in canine liver aspirates. AB - BACKGROUND: Canine hepatic copper content has been increasing. Recognition of canine copper-associated hepatopathies is becoming more common. OBJECTIVES: The purpose of the study was to assess the diagnostic performance of Wright-Giemsa (WG) and rhodanine staining for detection of increased canine hepatic copper following a proposed cytologic protocol for semi-quantitative evaluation of liver aspirates and the effect of previous WG staining. METHODS: Retrospectively, 40 canine hepatic WG-stained cytology cases were rhodanine stained. Diagnostic performance of WG staining for increased hepatic copper was evaluated. A rhodanine-stained cytologic copper grading system was developed. Prospectively, 67 canine liver samples with quantitative copper measurement, a WG-then rhodanine stained slide, and a non-WG rhodanine-stained slide were used to assess the performance of the grading system and the effect of previous WG staining. RESULTS: Copper was not described in 40 retrospective cases on initial cytologic evaluation; 8/40 cases had increased copper content after rhodanine staining or quantitative copper assessment. Prior WG staining and destaining significantly affected the cytologic copper grade but not the diagnostic performance as measured by receiver-operating characteristic curve analysis. Quantitative copper concentration and previously WG-stained copper grade were moderately correlated (n = 67, rho = .79 [.68-.87]). For detection of >= 600 ppm, dry weight (dw) copper, sensitivity was .75 and specificity was .97. For detection of >= 1500 ppm, dw copper, sensitivity was 1.0 and specificity was .97. CONCLUSIONS: Wright Giemsa staining alone does not reliably detect hepatic copper. Grading of rhodanine-stained canine hepatic cytologic samples demonstrates acceptable diagnostic performance for detection of copper content. PMID- 27701766 TI - Translation and reliability and validity testing of a Japanese version of the Intermittent Self-Catheterization Questionnaire among disposable and reusable catheter users. AB - AIMS: Quality of life in the context of intermittent self-catheterization varies depending on the type of catheter used. This study translated into Japanese, evaluated the feasibility, reliability, and validity of the Intermittent Self Catheterization Questionnaire (ISC-Q) among users of both reusable and disposable catheters, and examined the differences of it between them. METHODS: Seventy patients (age mean +/- SD: 62.8 +/- 17.7 years) completed the Japanese version of the ISC-Q (J-ISC-Q) at baseline and 4 weeks later. Spearman's correlation coefficients between the J-ISC-Q, and Qualiveen(r) and the SF-12 were used for the translated scale's discriminant and convergent validity. Reliability was evaluated by intraclass correlation coefficients (ICC), the Bland-Altman method, and Cronbach's alpha. RESULTS: Participants answered all questionnaire items with no difficulties. Scores on the convenience domain were significantly higher among reusable compared to disposable catheter users (P = 0.039). The J-ISC-Q had significantly strong correlations with the Qualiveen(r) total scale (rho = -0.712 to -0.237), but weak correlations with the SF-12 total scale (rho = -0.231 to 0.474). Internal consistency was good (Cronbach's alphas > 0.706), and test retest reliability was acceptable (ICC > 0.6) for the total scale and the four J ISC-Q domains. The Bland-Altman analysis showed no systematic error between scores at baseline and 4 weeks later for the total scale and four domains of the J-ISC-Q. CONCLUSIONS: The J-ISC-Q has acceptable reliability and validity for assessing both reusable and disposable catheter users, and can be used to promote tailored individualized interventions based on the impact of catheter use. PMID- 27701767 TI - Hematologic and biochemical reference intervals of free-living Red-Tailed Amazon parrot (Amazona brasiliensis) nestlings on Rasa Island, Parana, Brazil. AB - BACKGROUND: The Red-Tailed Amazon parrot (Amazona brasiliensis) is an endangered species of the Psittaciformes. There is little information about hematologic and biochemical variables of this species. OBJECTIVES: The purpose of this study was to determine hematologic and biochemical RIs for free-living A brasiliensis nestlings on Rasa Island, Parana, Brazil, and to compare the results between sexes. METHODS: Thirty-seven parrots were taken from their nests and physically restrained for clinical examination and blood collection. The sex was diagnosed by PCR using the blood samples collected. Reference intervals were determined as recommended by the ASVCP guidelines in healthy nestlings. The difference between groups was analyzed using the Mann-Whitney test or Student's t-test. RESULTS: Sexing revealed 12 females and 25 males. The RIs for the measured variables were as follows: RBC 1.1-2.6 * 106 /MUL, PCV 29.1-50.3%, HGB 7.2-12.9 g/dL, MCV 152 293 fL, MCHC 22.2-28.4 g/dL, WBC 4.9-28.5 * 103 /MUL, 1.2-16 * 103 /MUL, lymphocytes 2.4-18.7 * 103 /MUL, monocytes 0.0-1.0 * 103 /MUL, eosinophils 0.0 0.9 * 103 /MUL, 0.0-1.3 * 103 /MUL, heterophil:lymphocyte ratio 0.0-2.2, plasma total solids 2.1-3.7 g/dL, uric acid 0.5-2.0 mg/dL, glucose 184.9-284.3 mg/dL, AST 100.3-226.6 U/L, LDH 178.1-927.7 U/L, CK 149.8-1144.0 U/L, cholesterol 137.5 256.9 mg/dL, total protein 1.8-3.0 g/dL, calcium 7.0-8.6 mg/dL, and phosphorus 2.9-6.1 mg/dL. Increased concentrations of cholesterol (P < .05) were observed in females. DISCUSSION: This is the first study to establish hematologic and biochemical RIs for free-living A brasiliensis nestlings on Rasa Island. Hematologic and biochemical variables are important tools for evaluating the health status of free-living birds, and also support conservation planning for endangered species. PMID- 27701768 TI - Double phosphorylation-induced structural changes in the signal-receiving domain of IkappaBalpha in complex with NF-kappaB. AB - Activation of the transcription factor NF-kappaB requires degradation of its physiological inhibitor IkappaBalpha in order to allow nuclear translocation of NF-kappaB. NF-kappaB activity links inflammation and carcinogenesis and makes its signaling pathway an important target for therapeutic intervention. The signal receiving N-terminal domain (SRD) of the NF-kappaB inhibitor IkappaBalpha harbors the sites of post-translational modifications (Ser32 and 36) directed by the IkappaB kinase (IKK) complex. The SRD was originally recognized to be highly disordered, but was recently shown to possess stable secondary structural elements. Identifying and characterizing the structural effects that arise from phosphorylation may explain how phosphorylation regulates the IkappaBalpha-NF kappaB protein complex. Therefore, the effect of post-translational mono- and double-phosphorylation of the serine residues of the SRD was analyzed. The structural modifications of the IkappaBalpha-NF-kappaB protein-protein complex due to mono-phosphorylation of either Ser32 or Ser36 amino acid residues or simultaneous phosphorylation were investigated by means of molecular dynamics simulations. Mono-phosphorylation at either Ser32 or Ser36 was not sufficient to induce significant structural changes in the secondary structure of the SRD of IkappaBalpha. Double-phosphorylation yielded an increase in distance between the Calpha atoms of these serine residues, indicative of a structural change. Only this two-fold phosphorylation induced the extended, more stabilized conformation of the degron motif which renders it accessible by the E3 ligase. In summary, these results provide insight into the conformational changes induced in IkappaBalpha proteins upon phosphorylation that are vital to their signaling dynamics and enable us to propose a model for the phosphorylation of the SRD.

AB - AIMS: To assess the rates of incontinence and associated psychological problems in children, adolescents and adults with Down Syndrome, a genetic syndrome caused by partial or complete triplication (trisomy) of chromosome 21 and characterized by typical facial features, a physical growth delay and mild or moderate intellectual disability. METHODS: Three hundred and seventeen persons with Down Syndrome (4-51 years) were recruited through a German parent support group (59.6% male, mean age 19.2 years). The Parental Questionnaire: Enuresis/Urinary Incontinence, the Incontinence Questionnaire-Pediatric Lower Urinary Tract Symptoms, as well as the Developmental Behavior Checklist (DBC) for parents or for adults were filled out by parents or care-givers. RESULTS: 17.2% of the sample had nocturnal enuresis, 15.9% had daytime urinary incontinence, and 14.2% had fecal incontinence. Incontinence was present in 64.0% of young children (4-12 years), 10.3% of teens (13-17 years), 12.8% of young adults (18-30 years) and in 22.4% of older adults (>30 years). 13.6% of children and 8.4% of adults had a DBC score in the clinical range. 19.5% of children and 27.8% of adults with incontinence had behavioral problems. There was a significant association between nocturnal enuresis, daytime urinary incontinence and clinical DBC scores in adults. CONCLUSIONS: Incontinence in Down Syndrome is mainly present in young children and increases in older adults. Behavioral comorbidity is associated with incontinence only in adults with Down Syndrome. Screening and treatment of incontinence in individuals with Down Syndrome is recommended. PMID- 27701770 TI - Risk factors for infections in myelofibrosis: role of disease status and treatment. A multicenter study of 507 patients. AB - Although infectious complications represent a relevant cause of morbidity and mortality in patients with myelofibrosis (MF), little is known about their incidence, outcome and risk factors. We retrospectively evaluated a cohort of 507 MF patients, diagnosed between 1980 and 2014 in five Italian hematology centers, to define the epidemiology of infections and describe the impact of ruxolitinib (RUX) treatment. Overall, 112 patients (22%) experienced 160 infectious events (grade 3-4, 45%) for an incidence rate of 3.9% per patient-year. Infections were mainly bacterial (78%) and involving the respiratory tract (52% of cases). Also, viral (11%) and fungal infections (2%) were recorded. Overall, infections were fatal in 9% of the cases. Among baseline features, high/intermediate-2 IPSS category (HR 1.8, 95%CI:1.2-2.7; P = 0.02) and spleen length >=10 cm below left costal margin (HR 1.6, 95%CI:1.1-2.5; P = 0.04) were associated with higher infectious risk in multivariate analysis. Overall, the rate of infections was higher in the cohort of 128 RUX-treated patients (44% vs. 20%, P < 0.001). In conclusion, IPSS-category and splenomegaly, emerged as the main risk factors for infections in MF. RUX-treated patients experienced significantly more infection episodes; however, future prospective studies are needed to isolate the confounding contribution of other risk factors such as disease stage.

AB - AIM: There may be a link between disruption to the gut microbiota in early life and later neurocognitive outcomes. We hypothesised that antibiotic use in early life is associated with a detrimental effect on later neurocognitive outcomes. METHODS: Eight hundred and seventy-one European mothers and their children enrolled in the Auckland Birthweight Collaborative Study at birth. Information on antibiotic use during the first year of life and between 12 months and three-and a-half years of age was gathered via maternal interview. Intelligence test scores and measures of behavioural difficulties were obtained when children were three and-a-half years, seven years and 11 years of age. RESULTS: Antibiotic use in the first year of life was reported in 70% of the 526 children with antibiotic data assessed at age three-and-a-half years. Those who had received antibiotics had more behavioural difficulties and more symptoms of depression at follow-up. Results were consistent across all standardised psychologist administered tests, as well as parent rated, teacher rated and self-report measures. CONCLUSION: This study demonstrates an association between antibiotic use in the first year of life and subsequent neurocognitive outcomes in childhood. If confirmed by further research, these findings could have implications for the use of antibiotics for minor illnesses in infancy. PMID- 27701772 TI - Effects of an alpha1A/D-adrenoceptor antagonist, naftopidil, and a phosphodiesterase type 5 inhibitor, tadalafil, on urinary bladder remodeling in rats with spinal cord injury. AB - AIMS: In order to clarify whether an alpha1A/D-adrenoceptor (alpha1 A/D-AR) antagonist, naftopidil, or a phosphodiesterase type 5 (PDE5) inhibitor, tadalafil, prevents bladder wall remodeling after spinal cord injury (SCI), we examined the bladder and urethral activity as well as ischemic and fibrotic changes in the bladder using SCI rats with or without naftopidil or tadalafil treatment. METHODS: Adult female Sprague-Dawley rats were divided into four groups: (1) normal (spinal cord intact); (2) vehicle SCI; (3) naftopidil SCI; and (4) tadalafil SCI groups. In SCI groups, rats underwent Th9-10 spinal cord transection followed by oral application of vehicle, naftopidil (20 mg/kg/day) or tadalafil (2 mg/kg/day) for 1, 2, 4, 8, and 12 weeks. Bladder and urethral pressures, mRNA levels of fibrosis-related molecules and ischemia markers and the composition of bladder collagen and elastin were evaluated. RESULTS: Naftopidil treatment reduced the upregulation of mRNA levels of ischemia and fibrosis markers at the early phase of SCI, and ameliorated the decrease of bladder compliance and voiding efficiency, and the increase of urethral pressure and collagen concentration in the bladder wall at the late phase of SCI. Tadalafil treatment reduced the upregulation of mRNA levels of fibrosis markers, the decrease of bladder compliance and the increase of collagen concentration at the late phase of SCI. CONCLUSIONS: These results suggest that naftopidil and tadalafil treatments improved the bladder remodeling shown by increased bladder collagen contents after SCI in a different time course. Thus, these treatments could be effective for reducing the SCI-related tissue remodeling in the bladder. Neurourol. Urodynam. 9999:XX-XX, 2016. (c) 2016 Wiley Periodicals, Inc. PMID- 27701773 TI - Dissemination and Implementation Research in Marriage and Family Therapy: An Introduction and Call to the Field. AB - Despite the considerable resources allocated to research to promote public health, interventions capable of benefiting individuals and families are not finding their way into regular practice. An important avenue for addressing this problem is through dissemination and implementation (D&I) science, a burgeoning research area focusing on translating empirical knowledge into everyday practice. This article begins by suggesting ways in which MFTs are uniquely equipped to contribute to and benefit from D&I research. We will then provide an overview of D&I research, outlines key D&I models, and highlight examples of family intervention research relevant to MFTs using the key models. Finally, we conclude by providing the field with important next steps to advance the presence of MFT research within D&I scholarship. PMID- 27701774 TI - Thyroid eye disease: a review. AB - Thyroid eye disease is a multifactorial autoimmune disease with a spectrum of signs and symptoms. Oftentimes, the diagnosis of thyroid eye disease is straightforward, based upon history and physical examination. The purpose of this review is to assist the eye-care practitioner in staging the severity of thyroid eye disease (mild, moderate-to-severe and sight-threatening) and correlating available treatment modalities. Eye-care practitioners play an important role in the multidisciplinary team by assessing functional vision while also managing ocular health. PMID- 27701775 TI - Evaluation of intraocular pressure estimates obtained using an iCare rebound tonometer. AB - BACKGROUND: The aims of this study were to evaluate the intra- and inter-observer repeatability of intraocular pressure (IOP) estimates obtained using an iCare rebound tonometer and to investigate the variation in IOP measurements due to positional differences in probe placement on the cornea. METHODS: The IOP estimates were obtained by two observers, twice on one eye, of 114 subjects using an iCare tonometer on the central cornea. Additionally, IOP and corneal thickness were measured in 38 subjects at three locations, namely, central, at 1.5 mm nasally and at 1.5 mm temporally from the central cornea. Agreement among measurements was assessed using Bland and Altman plots and the difference in measurements obtained by the observers was compared using paired t-test. Values obtained from central, nasal and temporal regions were compared using one-way analysis of variance. RESULTS: The mean IOP measurements obtained by observer 1 on two attempts were 16.2 and 16.0 mmHg (p > 0.05) were significantly different from the IOP values obtained by observer 2 on two occasions (16.3 and 15.7 mmHg; p < 0.0001). The limits of agreement (LOA) of intra-observer repeatability were 2.9 to +2.6 mmHg and -3.4 to +2.2 for observers 1 and 2, respectively. The LOA of inter-observer repeatability for first and second sequences were -2.8 to +3.0 mmHg and -3.3 to +2.7 mmHg with the second sequence of measurements being significantly different (p = 0.03). Although the corneal thickness was significantly greater nasally and temporally, when compared to the central location, by 32 and 20 microns respectively (p < 0.0001), the measured IOPs on those locations were not significantly different, when compared to the central measurements (p = 0.14). CONCLUSION: There is good intra- and inter-observer repeatability of IOP data, as obtained by the iCare rebound tonometer, although the results may be slightly influenced by practitioner experience. The difference in IOP estimates obtained by different observers is unlikely to be of clinical significance. Corneal thickness showed regional variation; however, this did not influence IOP measurements obtained from those locations. PMID- 27701776 TI - pyDock scoring for the new modeling challenges in docking: Protein-peptide, homo multimers, and domain-domain interactions. AB - The sixth CAPRI edition included new modeling challenges, such as the prediction of protein-peptide complexes, and the modeling of homo-oligomers and domain domain interactions as part of the first joint CASP-CAPRI experiment. Other non standard targets included the prediction of interfacial water positions and the modeling of the interactions between proteins and nucleic acids. We have participated in all proposed targets of this CAPRI edition both as predictors and as scorers, with new protocols to efficiently use our docking and scoring scheme pyDock in a large variety of scenarios. In addition, we have participated for the first time in the servers section, with our recently developed webserver, pyDockWeb. Excluding the CASP-CAPRI cases, we submitted acceptable models (or better) for 7 out of the 18 evaluated targets as predictors, 4 out of the 11 targets as scorers, and 6 out of the 18 targets as servers. The overall success rates were below those in past CAPRI editions. This shows the challenging nature of this last edition, with many difficult targets for which no participant submitted a single acceptable model. Interestingly, we submitted acceptable models for 83% of the evaluated protein-peptide targets. As for the 25 cases of the CASP-CAPRI experiment, in which we used a larger variety of modeling techniques (template-based, symmetry restraints, literature information, etc.), we submitted acceptable models for 56% of the targets. In summary, this CAPRI edition showed that pyDock scheme can be efficiently adapted to the increasing variety of problems that the protein interactions field is currently facing.

PMID- 27701778 TI - The Dyadic Effects of Supportive Coparenting and Parental Stress on Relationship Quality Across the Transition to Parenthood. AB - The transition to first-time parenthood can be challenging for couples. Using a sample of 848 ethnically diverse couples from the Fragile Families and Child Wellbeing Study across the first 3 years of parenthood, we investigated the longitudinal and dyadic associations of each parents' parental stress, supportive coparenting, and relationship quality. Results from an actor-partner interdependence model indicated that supportive coparenting significantly predicted higher relationship quality for both mothers and fathers. Fathers' supportive coparenting significantly buffered the effects of mothers' parental stress on relationship quality. Also, the unique dyadic contexts of each parents' supportive coparenting, and also both partners' parental stress were significantly associated with relationship quality. Clinical implications from these findings are discussed through commonly used clinical theories. PMID- 27701779 TI - Urinary incontinence in the Netherlands: Prevalence and associated risk factors in adults. AB - AIMS: To determine the prevalence and risk factors associated with urinary incontinence (UI) among adults in the Netherlands. METHODS: In this cross sectional study, we included 1257 respondents aged >= 18 years, who completed the validated Groningen Defecation and Fecal Continence Checklist. UI was defined as any involuntary leakage of urine during the past 6 months. RESULTS: The prevalence of UI in the total group was 36.8%. Women experienced UI significantly more often than men (49.0% versus 22.6%, respectively, P < 0.001). We found that in both men and women, the prevalence of UI increased with aging (P = 0.003 and P < 0.001, respectively). Remarkably, multivariate analysis revealed that age did not influence UI in men. Men and women aged 18-39 also experienced UI (17.0% and 36.1%, respectively). We established that diabetes mellitus, fecal incontinence, and constipation were risk factors for UI. In women, obesity, vaginal hysterectomies, and vaginal parturition were also risk factors for UI, as was prostate surgery in men. CONCLUSIONS: The prevalence of UI in the Netherlands is high. Medical practitioners should therefore not underestimate this problem, especially among young people. Because the multivariate analysis revealed that in men age did not correlate significantly with UI, we believe that the risk of experiencing UI increases with age because of diseases that are known to lead to UI and not because of aging as a single factor itself. Finally, this study can be used as a reference for patients living in Western-Europe. PMID- 27701777 TI - Modeling complexes of modeled proteins. AB - Structural characterization of proteins is essential for understanding life processes at the molecular level. However, only a fraction of known proteins have experimentally determined structures. This fraction is even smaller for protein protein complexes. Thus, structural modeling of protein-protein interactions (docking) primarily has to rely on modeled structures of the individual proteins, which typically are less accurate than the experimentally determined ones. Such "double" modeling is the Grand Challenge of structural reconstruction of the interactome. Yet it remains so far largely untested in a systematic way. We present a comprehensive validation of template-based and free docking on a set of 165 complexes, where each protein model has six levels of structural accuracy, from 1 to 6 A Calpha RMSD. Many template-based docking predictions fall into acceptable quality category, according to the CAPRI criteria, even for highly inaccurate proteins (5-6 A RMSD), although the number of such models (and, consequently, the docking success rate) drops significantly for models with RMSD > 4 A. The results show that the existing docking methodologies can be successfully applied to protein models with a broad range of structural accuracy, and the template-based docking is much less sensitive to inaccuracies of protein models than the free docking.

AB - Computational protein-protein docking is of great importance for understanding protein interactions at the structural level. Critical assessment of prediction of interactions (CAPRI) experiments provide the protein docking community with a unique opportunity to blindly test methods based on real-life cases and help accelerate methodology development. For CAPRI Rounds 28-35, we used an automatic docking pipeline integrating the coarse-grained co-evolution-based potential InterEvScore. This score was developed to exploit the information contained in the multiple sequence alignments of binding partners and selectively recognize co evolved interfaces. Together with Zdock/Frodock for rigid-body docking, SOAP-PP for atomic potential and Rosetta applications for structural refinement, this pipeline reached high performance on a majority of targets. For protein-peptide docking and interfacial water position predictions, we also explored different means of taking evolutionary information into account. Overall, our group ranked 1st by correctly predicting 10 targets, composed of 1 High, 7 Medium and 2 Acceptable predictions. Excellent and Outstanding levels of accuracy were reached for each of the two water prediction targets, respectively. Altogether, in 15 out of 18 targets in total, evolutionary information, either through co-evolution or conservation analyses, could provide key constraints to guide modeling towards the most likely assemblies. These results open promising perspectives regarding the way evolutionary information can be valuable to improve docking prediction accuracy. Proteins 2017; 85:378-390.

AB - Ethylene plays diverse roles in plant growth, development and stress responses. However, the roles of ethylene signaling in immune responses remain largely unknown. In this study, we showed that the blast fungus Magnaporthe oryzae infection activated ethylene biosynthesis in rice. Resistant rice cultivars accumulated higher levels of ethylene than susceptible ones. Ethylene signaling components OsEIN2 and the downstream transcription factor OsEIL1 positively regulated disease resistance. Mutation of OsEIN2 led to enhanced disease susceptibility. Whole-genome transcription analysis revealed that responsive genes of ethylene, jasmonates (JAs) and reactive oxygen species (ROS) signaling as well as phytoalexin biosynthesis genes were remarkably induced. Transcription of OsrbohA/B, which encode NADPH oxidases, and OsOPRs, the JA biosynthesis genes, were induced by M. oryzae infection. Furthermore, we demonstrated that OsEIL1 binds to the promoters of OsrbohA/OsrbohB and OsOPR4 to activate their expression. These data suggest that OsEIN2-mediated OsrbohA/OsrbohB and OsOPR transcription may play essential roles in ROS generation, JA biosynthesis and the subsequent phytoalexin accumulation. Therefore, the involvement of ethylene signaling in disease resistance is probably by activation of ROS and phytoalexin production in rice during M. oryzae infection.

AB - AIM: To analyse the associations between childcare centres and infectious morbidity and resource consumption. METHODS: Cohort study from birth to 2 years. OUTCOME VARIABLE: number and types of infections, drug consumption and medical visits. Exposure variable: attending or not attending a childcare centre. School age: 6-12, >12-18, >18-24 months. RESULTS: The initial cohort comprised 445 children, and the final cohort comprised 419 children. The mean number of recurrent infections and wheezing was higher in children attending childcare centres in all age groups with significant differences. Recurrent acute otitis media was observed in the 12- to 18-month group with an odds ratio of 6.04 (95% confidence interval, 1.3-27.6; P = 0.001) in the children attending childcare centres. In children older than 6 months, there was greater consumption of antibiotics, inhaled bronchodilators, oral and inhaled corticosteroids and montelukast. CONCLUSIONS: Attending a childcare is associated with an increased frequency of recurrent infections and wheezing, as well as the consumption of antibiotics, bronchodilators, corticosteroids and montelukast. PMID- 27701785 TI - Paediatric lymphoedema: A retrospective chart review of 86 cases. AB - AIM: To define the clinical characteristics, investigations, management and outcomes of lymphoedema in a paediatric cohort. METHODS: A retrospective chart review of children with lymphoedema seen at two tertiary paediatric hospitals since 1998. Telephone interviews with parents were performed when information was missing. Information recorded included demographic data, features of diagnosis and clinical presentation, symptoms, complications and treatment. RESULTS: A total of 86 patients with lymphoedema were identified. Eighty cases (93%) were primary and six cases (7%) were secondary. Most were female (60%). Location of swelling was most commonly the lower limbs (94%). There were 13 cases (15%) of genital involvement. Swelling presented in the first 12 months of life in 60% of primary lymphoedema patients. Complications of lymphoedema occurred in 73% of patients. Lymphoscintigraphy was the most common investigation used (65%), followed by ultrasound (57%) and magnetic resonance imaging (MRI) (35%). Eight of the 48 (17%) lymphoscintigraphs produced a false negative result or were inconclusive with a correct diagnosis subsequently made clinically and using MRI. Average time to diagnosis was 9 months. Lymphoedema was managed with compression garments (99%), manual lymph drainage (97%) and multilayered bandaging (68%). Eight patients had an operative procedure as a part of management. CONCLUSIONS: Primary lymphoedema is more common than secondary lymphoedema in children. Onset tends to be during infancy for both males and females, and the lower limb is typically involved. Causes of secondary lymphoedema are diverse and rare. Diagnosis in children is often delayed but is possible based on history and physical examination alone and when further investigation is necessary MRI is effective. PMID- 27701786 TI - Environmental enrichment and physical exercise revert behavioral and electrophysiological impairments caused by reduced adult neurogenesis. AB - It is well known that adult neurogenesis occurs in two distinct regions, the subgranular zone of the dentate gyrus and the subventricular zone along the walls of the lateral ventricles. Until now, the contribution of these newly born neurons to behavior and cognition is still uncertain. The current study tested the functional impacts of diminished hippocampal neurogenesis on emotional and cognitive functions in transgenic Gfap-tk mice. Our results showed that anxiety related behavior evaluated both in the elevated plus maze as well as in the open field, social interaction in the sociability test, and spatial working memory in the spontaneous alternation test were not affected. On the other hand, recognition and emotional memory in the object recognition test and contextual fear conditioning, and hippocampal long-term potentiation were impaired in transgenic mice. Furthermore, we evaluated whether environmental enrichment together with physical exercise could improve or even restore the level of adult neurogenesis, as well as the behavioral functions. Our results clearly demonstrated that environmental enrichment together with physical exercise successfully elevated the overall number of progenitor cells and young neurons in the dentate gyrus of transgenic mice. Furthermore, it led to a significant improvement in object recognition memory and contextual fear conditioning, and reverted impairments in hippocampal long-term potentiation. Thus, our results confirm the importance of adult neurogenesis for learning and memory processes and for hippocampal circuitry in general. Environmental enrichment and physical exercise beneficially influenced adult neurogenesis after it had been disrupted and most importantly recovered cognitive functions and long-term potentiation.

AB - AIM: The aim of this study is to analyse the effect of delayed diagnosis on mortality rates, and evaluate the role of delayed diagnosis as a new prognostic factor in patients with oesophageal atresia (OA), especially in developing countries. METHODS: The records of 80 consecutive patients with OA (2008-2013) were reviewed. Patients were divided into two groups according to the time of diagnosis. As we demonstrated the effect of delayed diagnosis on mortality, we decided to develop a new classification that will be utilised to predict the prognosis of OA. The discrimination ability of the new prognostic classification was compared with those of the Waterston, Montreal and Spitz classifications using the area under the curve. RESULTS: The parameters of the new prognostic classification were birth weight less than 2000 g, the presence of major cardiac/life-threatening anomalies and delay in diagnosis. Class I consisted of patients with none or one of these parameters. Class II consisted of patients with two or three of these parameters. The area under the curve of the new classification was better than those of the other classifications in determining the prognosis of patients with OA. CONCLUSIONS: Delayed diagnosis of OA significantly led to morbidity and mortality. Although delayed diagnosis is not a characteristic of newborn or a marker of severity for OA and is a health care system issue in developing countries, we here point out that it is a prognostic factor in its own right. Our new classification has a superior discriminatory ability compared to the above-mentioned classifications. PMID- 27701788 TI - Pleiotropic function of TRPV4 ion channels in the central nervous system. AB - NEW FINDINGS: What is the topic of this review? In this concise review, we highlight insights into the role of transient receptor potential, vanilloid type 4 (TRPV4) ion channels in the CNS, results that have been contributed over the last 16 years since the initial discovery of the channel. What advances does it highlight? TRPV4 has been found to function in neurons, astroglia and microglia, both in physiological (e.g. astrocytic neurovascular coupling, neuronal membrane potential at physiological temperature) and in pathological conditions (e.g. mechanical trauma), so far recorded as exciting findings in need of more in-depth mechanistic clarification. Transient receptor potential, vanilloid type 4 (TRPV4) ion channels are osmo-mechano-TRP channels, with pleiotropic function and expression in many different types of tissues and cells. They have also been found to be involved in pain and inflammation. Studies have focused on the role of TRPV4 in peripheral sensory neurons, but its expression and function in central nervous glial cells and neurons has also been documented. In this overview, based on the senior author's (WL) lecture at the recent recent joint meeting of APS/The Physiological Society in Dublin, we concisely review evidence of TRPV4 expression and function in the CNS and how TRPV4 function can be modulated for therapeutic benefit of neuropsychiatric disorders. Novel TRPV4 inhibitory compounds developed recently in the authors' laboratory are also discussed. PMID- 27701789 TI - Acute pancreatitis complicating choledochal cysts in children. AB - AIM: To analyse the characteristics of patients with choledochal cysts presenting with acute pancreatitis. METHODS: Multicenter retrospective review of all paediatric patients (<18 years) with choledochal cysts managed over a 14-year period (2001-2014) at two tertiary paediatric surgical centres. Patient data were analysed for demographics, presentation, radiological classification of cyst type (Todani), operative interventions, complications and long-term follow-up. RESULTS: A total of 49 patients with choledochal cysts were identified with 15 (31%) being Type I fusiform, 18 (37%) Type I cystic and 16 (32%) Type IV-A. Seventeen (35%) patients presented with acute pancreatitis, one having had an ante-natally diagnosed choledochal cyst. Patients presenting with pancreatitis were older when compared to the non-pancreatitis group (5.1 vs. 1.2 years, P = 0.005). Nine out of 16 (53%) patients with Type IV-A cysts presented with pancreatitis compared to five (33%) of Type I fusiform and three (17%) of Type I cystic. There was however no statistically significant association between Todani types and the development of pancreatitis (Type I fusiform, P = 1.0; Type I cystic, P = 0.063; Type IV-A, P = 0.053). The rate of complications was similar in both groups. CONCLUSION: Pancreatitis was a common presentation in children with a choledochal cyst, however, there was no clear statistically significant association with Todani types and pancreatitis. PMID- 27701790 TI - Six-year trajectory of objective physical function in persons with depressive and anxiety disorders. AB - BACKGROUND: Depression and anxiety have been related to poorer self-reported physical functioning over time; however, objective measures of physical function are less frequently examined. This study assessed the 6-year trajectory of hand grip strength and lung function in persons with depressive and/or anxiety disorders. METHODS: At four waves (baseline, 2, 4, and 6 years) hand-grip strength and lung function were assessed in 2,480 participants, aged 18-65 years, of the Netherlands Study of Depression and Anxiety. Linear mixed models were used to examine the association between baseline psychiatric status (current and remitted depression and anxiety, healthy controls) and physical function during 6 year follow-up, adjusted for sociodemographics, lifestyle, and health indicators. RESULTS: Although there were no differences in the rate of decline over time, women with current, but not remitted, depression and anxiety had poorer hand-grip strength (B = -1.34, P < .001) and poorer lung function (B = -11.91, P =.002) compared to healthy women during the entire 6-year follow-up. Associations with depression and anxiety severity measures confirmed dose-response relationships with objective physical function. In men, stronger 6-year decline of lung function was found in those with current disorders (current diagnosis-by-time: B = -11.72, P = .002) and even in those with remitted disorders (remitted diagnosis by time: B = -10.11, P = .04) compared to healthy men. CONCLUSIONS: Depression and anxiety are associated with consistently poorer hand-grip strength in women and poorer lung function in women and men over 6 years of time, implicating their long-lasting impact on physical functioning. PMID- 27701791 TI - Utilization of Mental Health Services by Veterans Living in Rural Areas. AB - PURPOSE: There is concern that veterans living in rural areas may not be receiving the mental health (MH) treatment they need. This study uses recent national survey data to examine the utilization of MH treatment among military veterans with a MH condition living in rural areas, providing comparisons with estimates of veterans living in urban areas. METHODS: Multivariable logistic regression is utilized to examine differences in MH service use by urban/rural residence, controlling for other factors. Rates of utilization of inpatient and outpatient treatment, psychotropic medication, any MH treatment, and perceived unmet need for MH care are examined. FINDINGS: There were significant differences in MH treatment utilization among veterans by rural/urban residence. Multivariate estimates indicate that compared to veterans with a MH condition living in urban areas, veterans in rural areas had 70% lower odds of receiving any MH treatment. Veterans with a MH condition in rural areas have approximately 52% and 64% lower odds of receiving outpatient treatment and prescription medications, respectively, compared to those living in urban areas. Differences in perceived unmet need for mental health treatment were not statistically significant. CONCLUSIONS: While research indicates that recent efforts to improve MH service delivery have resulted in improved access to services, this study found that veterans' rates of MH treatment are lower in rural areas, compared to urban areas. Continued efforts to support the provision of behavioral health services to rural veterans are needed. Telemedicine, using rural providers to their maximum potential, and engagement with community stakeholder groups are promising approaches. PMID- 27701792 TI - Active place avoidance is no more stressful than unreinforced exploration of a familiar environment. AB - Training in the active place avoidance task changes hippocampus synaptic function, the dynamics of hippocampus local field potentials, place cell discharge, and active place avoidance memory is maintained by persistent PKMzeta activity. The extent to which these changes reflect memory processes and/or stress responses is unknown. We designed a study to assess stress within the active place avoidance task by measuring serum corticosterone (CORT) at different stages of training. CORT levels did not differ between trained mice that learned to avoid the location of the mild foot shock, and untrained no-shock controls exposed to the same environment for the same amount of time. Yoked mice, that received unavoidable shocks in the same time sequence as the trained mice, had significantly higher CORT levels than mice in the trained and no-shock groups after the first trial. This increase in CORT disappeared by the fourth trial the following day, and levels of CORT for all groups matched that of home cage controls. The data demonstrate that place avoidance training is no more stressful than experiencing a familiar environment. We conclude that changes in neural function as a result of active place avoidance training are likely to reflect learning and memory processes rather than stress. (c) 2016 Wiley Periodicals, Inc. PMID- 27701793 TI - 11p15 ICR1 Partial Deletions Associated with IGF2/H19 DMR Hypomethylation and Silver-Russell Syndrome. AB - The 11p15 region harbors the IGF2/H19 imprinted domain, implicated in fetal and postnatal growth. Silver-Russell syndrome (SRS) is characterized by fetal and postnatal growth failure, and is caused principally by hypomethylation of the 11p15 imprinting control region 1 (ICR1). However, the mechanisms leading to ICR1 hypomethylation remain unknown. Maternally inherited genetic defects affecting the ICR1 domain have been associated with ICR1 hypermethylation and Beckwith Wiedemann syndrome (an overgrowth syndrome, the clinical and molecular mirror of SRS), and paternal deletions of IGF2 enhancers have been detected in four SRS patients. However, no paternal deletions of ICR1 have ever been associated with hypomethylation of the IGF2/H19 domain in SRS. We screened for new genetic defects within the ICR1 in a cohort of 234 SRS patients with hypomethylated IGF2/H19 domain. We report deletions close to the boundaries of ICR1 on the paternal allele in one familial and two sporadic cases of SRS with ICR1 hypomethylation. These deletions are associated with hypomethylation of the remaining CBS, and decreased IGF2 expression. These results suggest that these regions are most likely required to maintain methylation after fertilization. We estimate these anomalies to occur in about 1% of SRS cases with ICR1 hypomethylation. PMID- 27701795 TI - Adequacy of palliative care in a single tertiary neonatal unit. AB - AIM: End-of-life care remains part of the scope of practice in all neonatal units. This study aimed to characterise the end-of-life care provided in an Australian tertiary neonatal centre, where paediatric palliative care was accessible via a consultative service. METHODS: This retrospective cohort study examined indicators of quality palliative care provided to 46 infants born within a 30-month period. The cohort included four infants who received palliative care consultations additional to usual neonatal care. The care provided was characterised using descriptive statistics. RESULTS: The most common causes of death were congenital abnormality (37%) and complications of extreme prematurity (22%). Very high proportions of infants and families had family meetings (100%), social worker involvement (100%), memory-making opportunities (100%) and discussion of autopsy (91%). Opiates were prescribed to 76% in the last day of life; most (89%) were administered intravenously. For those prescribed opiates, the median parenteral morphine daily equivalent was 290 mcg/kg/day (interquartile range = 317) in the last 24 h of life. Antenatal resuscitation planning for families of a fetus with a prenatal diagnosis (9%), discussion of preferred location of death (9%), verbal communication with general practitioners (15%) and access to specialised bereavement care (3%) were infrequently provided. CONCLUSIONS: At the time of this study, the neonatal unit was not meeting all of the end-of-life care needs of infants and their families. Care was generally more comprehensive when the palliative care service was consulted. PMID- 27701794 TI - GABAergic hyperinnervation of dentate granule cells in the Ts65Dn mouse model of down syndrome: Exploring the role of App. AB - It has been suggested that increased GABAergic innervation in the hippocampus plays a significant role in cognitive dysfunction in Down syndrome (DS). Bolstering this notion, are studies linking hyper-innervation of the dentate gyrus (DG) by GABAergic terminals to failure in LTP induction in the Ts65Dn mouse model of DS. Here, we used extensive morphometrical methods to assess the status of GABAergic interneurons in the DG of young and old Ts65Dn mice and their 2N controls. We detected an age-dependent increase in GABAergic innervation of dentate granule cells (DGCs) in Ts65Dn mice. The primary source of GABAergic terminals to DGCs somata is basket cells (BCs). For this reason, we assessed the status of these cells and found a significant increase in the number of BCs in Ts65Dn mice compared with controls. Then we aimed to identify the gene/s whose overexpression could be linked to increased number of BCs in Ts65Dn and found that deleting the third copy of App gene in Ts65Dn mice led to normalization of the number of BCs in these mice. Our data suggest that App overexpression plays a major role in the pathophysiology of GABAergic hyperinnervation of the DG in Ts65Dn mice. (c) 2016 Wiley Periodicals, Inc. PMID- 27701796 TI - Persistence of impulsivity in pediatric and adolescent patients with obsessive compulsive disorder. AB - AIM: Increasing clinical evidence points to impulsivity as a symptom of obsessive compulsive disorder (OCD). However, little is known about its persistence over time. METHODS: In this study, we evaluated the performance of 12 pediatric patients with OCD on the Stroop color-word task, which assesses impulsivity, and compared this with age- and sex-matched controls. In parallel, we measured changes in hemodynamic responses during the task, using near-infrared spectroscopy. As patients in the OCD group were naive to treatment, we compared results before and after 3-year medication with serotonin reuptake inhibitors. RESULTS: We report that, compared with controls, the OCD group had significantly poorer performance and less activation in the prefrontal cortex during the Stroop color-word task. Surprisingly, while serotonin-reuptake-inhibitors treatment reduced OCD symptomology, it did not improve the diminished hemodynamic responses or task performance of these patients. CONCLUSION: Our findings suggest that a persistent deficit exists in the inhibitory control of pediatric patients with OCD; they also provide insight into the pathophysiology of OCD. PMID- 27701797 TI - Opposite in vivo effects of agents that stimulate or inhibit the glutamate/cysteine exchanger system xc- on the inhibition of hippocampal LTP by Abeta. AB - Aggregated amyloid beta-protein (Abeta) is pathognomonic of Alzheimer's disease and certain assemblies of Abeta are synaptotoxic. Excess glutamate or diminished glutathione reserve are both implicated in mediating or modulating Abeta-induced disruption of synaptic plasticity. The system xc- antiporter promotes Na+ independent exchange of cystine with glutamate thereby providing a major source of extracellular glutamate and intracellular glutathione concentrations. Here we probed the ability of two drugs with opposite effects on system xc-, the inhibitor sulfasalazine and facilitator N-acetylcysteine, to modulate the ability of Abeta1-42 to inhibit long-term potentiation (LTP) in the CA1 area of the anaesthetized rat. Whereas acute systemic treatment with sulfasalazine lowered the threshold for Abeta to interfere with synaptic plasticity, N-acetylcysteine prevented the inhibition of LTP by Abeta alone or in combination with sulfasalazine. Moreover acute N-acetylcysteine also prevented the inhibition of LTP by TNFalpha, a putative mediator of Abeta actions, and repeated systemic N acetylcysteine treatment for 7 days reversed the delayed deleterious effect of Abeta on LTP. Since both of these drugs are widely used clinically, further evaluation of their potential beneficial and deleterious actions in early Alzheimer's disease seems warranted.

PMID- 27701803 TI - Eligibility criteria for therapeutic hypothermia: From trials to clinical practice. AB - AIM: Whole body therapeutic hypothermia (TH) for hypoxic ischaemic encephalopathy was introduced into clinical practice in New South Wales (NSW) and Australian Capital Territory in 2007. State-wide policy adopting the eligibility criteria and practice based on trial-designs was published in 2009. METHODS: The study was conducted by retrospectively reviewing medical records of all TH infants born between 2007 and 2011 in NSW and Australian Capital Territory to examine if eligibility criteria (assessed against evidence-based policy directives) were met. RESULTS: A total of 207 infants received TH, 104 (50%) did not meet the eligibility criteria defined in NSW policy directive. Over the 5-year period, the proportion of infants meeting the eligibility criteria did not change. Seventy percent of infants (73 out of 104) not meeting eligibility criteria did not fulfil the criteria for 'evidence of asphyxia', although half of them met 'moderate or severe encephalopathy criterion'. Adverse events (hypotension, coagulopathy and arrhythmia), were more common in the 'criteria met' group than the 'criteria not met' group (89 vs. 71%, P = 0.001). Similar proportions of infants had TH discontinued before 72 h (criteria met: 32 (31%) vs. criteria not met: 27(26%)). Most frequent reason for early cessation was 'palliation' (19/32, 59%) in criteria met and 'clinical improvement' (16/27, 59%) in criteria not met group. CONCLUSIONS: Many TH infants were treated based on clinician judgement, though not meeting the trial-design policy criteria. Early TH cessation (<72 h) was common. Future studies are warranted on long-term neurodevelopmental outcomes for all infants receiving TH particularly those with early cessation of therapy. PMID- 27701804 TI - Deactivation of Mcl-1 by Dual-Function Small-Molecule Inhibitors Targeting the Bcl-2 Homology 3 Domain and Facilitating Mcl-1 Ubiquitination. AB - By means of limited proteolysis assay, three-dimensional NMR, X-ray crystallography and alanine mutations, a dynamic region at the Q221R222N223 motif in the Bcl-2 homology 3 (BH3) domain of Mcl-1 has been identified as a conformational switch which controls Mcl-1 ubiquitination. NoxaBH3 binding biases the QRN motif toward a helical conformation, thus leading to an enhanced in vitro ubiquitination of Mcl-1. In contrast, BimBH3 binding biases the QRN motif toward a nonhelical conformation, thus leading to the inhibition of ubiquitination. A dual function Mcl-1 inhibitor, which locates at the BH3 domain of Mcl-1 and forms hydrogen bond with His224 to drive a helical QRN conformation, so that it not only interferes with the pro-apoptotic partners, but also facilitates Mcl-1 ubiquitination in living cells, is described. As a result, this inhibitor manifests a more effective apoptosis induction in Mcl-1-dependent cancer cells than other inhibitors exhibiting a similar binding affinity with it. PMID- 27701805 TI - Recent Developments in Coinage Metal Catalyzed Transformations of Stabilized Vinyldiazo Compounds: Beyond Carbenic Pathways. AB - Transition metal-catalyzed transformations of vinyldiazo compounds have become a versatile tool in organic synthesis. Although several transition metals have been investigated for this purpose, this field has been mainly dominated by dirhodium catalysts. Remarkable levels of chemo-, regio-, diastereo- and enantioselectivity have been reached in some of these rhodium-catalyzed transformations. In the last few years coinage metals have also emerged as useful catalysts in transformations involving vinyldiazo compounds. In some cases, highly efficient catalyst dependent protocols arising from divergent mechanistic pathways have been reported. In this Personal Account, we aim to showcase recent advances in metal coinage catalyzed transformations of vinyldiazoacetates, an exciting field of research to which our group has actively contributed in the last few years. PMID- 27701806 TI - Photosensitizing Electron Transfer Processes of Fullerenes, Carbon Nanotubes, and Carbon Nanohorns. AB - In this account, studies on the photosensitizing electron transfer of nanocarbons, such as fullerenes, single-walled carbon nanotubes (SWCNTs), and carbon nanohorns (CNH), performed in our laboratory for about 15 years in the early 21st century have been briefly reviewed. These novel nanocarbons act as excellent electron acceptors, when they are linked to light-absorbing electron donors, such as porphyrins or phthalocyanines. For such molecule-nanocarbon hybrids, the direct confirmation of fast, transient, electron-transfer phenomena must be performed with time-resolved spectroscopic methods, such as transient absorption spectral measurements, in addition to fluorescence time-profile measurements in the wide-wavelength regions. Careful use of these methods affords useful information to understand photoinduced electron-transfer mechanisms. In addition, kinetic data obtained by these methods can assist in the construction of light-active devices, such as photovoltaic cells and solar H2 -generation systems.

AB - Oxygen- and nitrogen-containing heterocyclic compounds are widely recognized as key components in many natural products and biologically relevant molecules, but often the problem comes down to methodologies in synthesizing them. Halocyclization of olefinic substrates is a promising strategy in the construction of O- and N-heterocyclic compounds, which further signifies the development of their asymmetric variants. Over the past years, our group has been devoted to this particular area of asymmetric electrophilic halocyclization with chalcogen-containing molecules as catalysts. In this account, the main focus is on the development of our novel chiral catalysts and applications derived from the reaction products.

As 1,2-acyl or phosphoryl migration is preferred, single regioisomers are obtained. Furthermore, in the presence of a Lewis acid, subsequent Friedel-Crafts reactions yield tricyclic pyrrolizidines in excellent yields (90-96 %) and diastereoselectivities (up to >20:1). PMID- 27701809 TI - Bioactive and inert dental glass-ceramics. AB - The global market for dental materials is predicted to exceed 10 billion dollars by 2020. The main drivers for this growth are easing the workflow of dentists and increasing the comfort of patients. Therefore, remarkable research projects have been conducted and are currently underway to develop improved or new dental materials with enhanced properties or that can be processed using advanced technologies, such as CAD/CAM or 3D printing. Among these materials, zirconia, glass or polymer-infiltrated ceramics, and glass-ceramics (GCs) are of great importance. Dental glass-ceramics are highly attractive because they are easy to process and have outstanding esthetics, translucency, low thermal conductivity, high strength, chemical durability, biocompatibility, wear resistance, and hardness similar to that of natural teeth, and, in certain cases, these materials are bioactive. In this review article, we divide dental GCs into the following two groups: restorative and bioactive. Most restorative dental glass-ceramics (RDGCs) are inert and biocompatible and are used in the restoration and reconstruction of teeth. Bioactive dental glass-ceramics (BDGCs) display bone bonding ability and stimulate positive biological reactions at the material/tissue interface. BDGCs are suggested for dentin hypersensitivity treatment, implant coating, bone regeneration and periodontal therapy. Throughout this paper, we elaborate on the history, processing, properties and applications of RDGCs and BDGCs. We also report on selected papers that address promising types of dental glass-ceramics. Finally, we include trends and guidance on relevant open issues and research possibilities.

AB - In this study, the possible uses of glassworts as potential food ingredients and their antiproliferative activity against colorectal adenocarcinoma cells together with their antioxidant and phytochemical profiles were investigated for the first time. MeOH extracts of five different taxa collected from different localities were screened for their antioxidant capacities by DPPH (IC50 2.91 - 5.49 mg/ml) and ABTS (24.4 - 38.5 MUmol TE/g extract) assays. Salicornia freitagii exhibited the highest DPPH radical scavenging activity. LC/MS/MS analysis displayed that vanillic acid and p-coumaric acid were two main phenolic compounds in the extract. Salicornia freitagii extracts also exhibited high antiproliferative activity against HT-29 (IC50 1.67 mg/ml) and Caco-2 (IC50 3.03 mg/ml) cells for 72 h. Mineral analysis indicated that all the species with different proportions of elemental components contained high amount of cations.

AB - A fundamentally simple, mild, and practical procedure for peptide bond formation is reported that employs a stoichiometric amount of easy-to-access 9 silafluorenyl dichlorides as the coupling agent. Without initial preactivation or elaboration of the carboxylic acid or amine termini of the amino acids, the developed reagent is proposed to act through an unprecedented chemical ligation mechanism, bringing the two coupling partners together before being subsequently eliminated. The desired amides or peptide bonds are thus furnished in good yields and with low to no epimerization.

AB - Lavandula pubescens Decne. is one of five Lavandula species growing wild in Yemen. The plant is used in Yemeni traditional medicine, and the essential oil tends to be rich in carvacrol. In this work, L. pubescens was collected from eight different locations in Yemen, the essential oils obtained by hydrodistillation, and the oils analyzed by gas chromatography/mass spectrometry (GC/MS). Principal component analysis (PCA) and hierarchical cluster analysis (HCA) were used to differentiate between the L. pubescens samples. The essential oils were rich in carvacrol (60.9 - 77.5%), with lesser concentrations of carvacrol methyl ether (4.0 - 11.4%), caryophyllene oxide (2.1 - 6.9%), and terpinolene (0.6 - 9.2%). The essential oil compositions in this study showed very high similarity, but it was possible to discern two separate groups based on minor components, in particular the concentrations of terpinolene, carvacrol methyl ether, m-cymen-8-ol, and caryophyllene oxide.

AB - In cochlear implant (CI) patients, an increase in electrode impedance due to fibrotic encapsulation is frequently observed. Several attempts have been proposed to reduce fibroblast growth at the electrode contacts, but none proved to be satisfactory so far. Here, a silicone fiber coating of the electrode contacts is presented that provides a complex micro-scale surface topography and increases hydrophobicity to inhibit fibroblast growth and adhesion. A silicone fiber electrospinning process was developed to create a thin and porous fiber mesh. Fiber coatings were applied on graphite specimen holders, glass cover slips and CI electrode contacts. For characterization of the coating's pore distribution, water contact angle and electrical impedance were analyzed. Cytotoxicity and in vitro fibroblast growth were evaluated to assess biological efficacy of the coatings. It could be shown that the silicone fiber mesh itself had only minor influence on electrode impedance. A uniform, hydrophobic fiber coating could be achieved that decreased fibroblast growth without showing toxic effects. Finally, CI electrode contacts were successfully coated in order to present this promising approach for a long-term improvement of CI electrodes. We are one of the first groups that could successfully adapt the electrospinning technique on the utilization of silicone. Silicone was chosen because of its high hydrophobicity, chemical stability and excellent biocompatibility and as it is one of the biomaterials already used in CIs. (c) 2016 Wiley Periodicals, Inc.

AB - Enzyme catalysis relies on conformational plasticity, but structural information on transient intermediates is difficult to obtain. We show that the three dimensional (3D) structure of an unstable, low-abundance enzymatic intermediate can be determined by nuclear magnetic resonance (NMR) spectroscopy. The approach is demonstrated for Staphylococcus aureus sortase A (SrtA), which is an established drug target and biotechnological reagent. SrtA is a transpeptidase that converts an amide bond of a substrate peptide into a thioester. By measuring pseudocontact shifts (PCSs) generated by a site-specific cysteine-reactive paramagnetic tag that does not react with the active-site residue Cys184, a sufficient number of restraints were collected to determine the 3D structure of the unstable thioester intermediate of SrtA that is present only as a minor species under non-equilibrium conditions. The 3D structure reveals structural changes that protect the thioester intermediate against hydrolysis.

AB - The Morita-Baylis-Hillman (MBH) reaction is one of the most useful and efficient protocols for constructing new carbon-carbon bonds between an activated olefin and electrophiles in the presence of a tertiary amine/phosphine. Herein, we present the use of MBH alcohols, which are obtained from the reaction of nitrostyrenes with aldehydes, as well as acetates and amines derived thereof in several organocatalytic transformations. Densely functionalised MBH adducts can also be used to synthesise substituted heteroaromatic compounds, such as furan, pyrrole, pyrazole and imidazole derivatives. PMID- 27701817 TI - The Origin of Improved Electrical Double-Layer Capacitance by Inclusion of Topological Defects and Dopants in Graphene for Supercapacitors. AB - Low-energy density has long been the major limitation to the application of supercapacitors. Introducing topological defects and dopants in carbon-based electrodes in a supercapacitor improves the performance by maximizing the gravimetric capacitance per mass of the electrode. However, the main mechanisms governing this capacitance improvement are still unclear. We fabricated planar electrodes from CVD-derived single-layer graphene with deliberately introduced topological defects and nitrogen dopants in controlled concentrations and of known configurations, to estimate the influence of these defects on the electrical double-layer (EDL) capacitance. Our experimental study and theoretical calculations show that the increase in EDL capacitance due to either the topological defects or the nitrogen dopants has the same origin, yet these two factors improve the EDL capacitance in different ways. Our work provides a better understanding of the correlation between the atomic-scale structure and the EDL capacitance and presents a new strategy for the development of experimental and theoretical models for understanding the EDL capacitance of carbon electrodes. PMID- 27701818 TI - Molecular Imaging of Growth, Metabolism, and Antibiotic Inhibition in Bacterial Colonies by Laser Ablation Electrospray Ionization Mass Spectrometry. AB - Metabolism in microbial colonies responds to competing species, rapidly evolving genetic makeup, and sometimes dramatic environmental changes. Conventional characterization of the existing and emerging microbial strains and their interactions with antimicrobial agents, e.g., the Kirby-Bauer susceptibility test, relies on time consuming methods with limited ability to discern the molecular mechanism and the minimum inhibitory concentration. Assessing the metabolic adaptation of microbial colonies requires their non-targeted molecular imaging in a native environment. Laser ablation electrospray ionization (LAESI) is an ambient ionization technique that in combination with mass spectrometry (MS) enables the analysis and imaging of numerous metabolites and lipids. In this contribution, we report on the application of LAESI-MS imaging to gain deeper molecular insight into microbe-antibiotic interactions, and enhance the quantitative nature of antibiotic susceptibility testing while significantly reducing the required incubation time. PMID- 27701819 TI - A Two-Step Method for Transferring Single-Walled Carbon Nanotubes onto a Hydrogel Substrate. AB - Carbon nanotube (CNT)-hydrogel nanocomposites are beneficial for various biomedical applications, such as nerve regeneration, tissue engineering, sensing, or implant coatings. Still, there are impediments to developing nanocomposites, including attaining a homogeneous CNT-polymer dispersion or patterning CNTs on hydrogels. While few approaches have been reported for patterning CNTs on polymeric substrates, these methods include high temperature, high vacuum or utilize a sacrificial layer and, hence, are incompatible with hydrogels as they lead to irreversible collapse in hydrogel structure. In this study, a novel two step method is designed to transfer CNTs onto hydrogels. First, dense CNTs are grown on quartz substrates. Subsequently, hydrogel solutions are deposited on the quartz-grown CNTs. Upon gelation, the hydrogel with transferred CNTs is peeled from the quartz. Successful transfer is confirmed by scanning electron microscopy and indirectly by cell attachment. The efficient transfer is attributed to pi interactions pregelation between the polymers in solution and the CNTs. PMID- 27701820 TI - Detection of intermolecular transferred NOEs in large protein complexes using asymmetric deuteration: HIV-1 gp120 in complex with a CCR5 peptide. AB - Weak protein-protein and protein-ligand interactions play important roles in biological recognition. In many cases, simplification of structural studies of large protein complexes is achieved by investigation of the interaction between the protein and a weakly binding segment of its protein ligand. Detection of pairwise interactions in such complexes is a major challenge for both X-ray crystallography and nuclear magnetic resonance. We demonstrate that transferred nuclear Overhauser effect (TRNOE), in combination with asymmetric deuteration of a protein and a peptide ligand can be used to detect intermolecular interactions in large protein complexes with molecular weights up to ~ 100 kDa. Using this approach, we revealed interactions between tyrosine residues of a 27-residue peptide (deuterated at Ile and Val residues) corresponding to the N-terminal segment of the human C-C chemokine receptor 5 (CCR5) chemokine receptor, and a 43 kDa construct of gp120 envelope protein of human immunodeficiency virus type 1 (deuterated on all aromatics) complexed with a cluster of differentiation 4-mimic miniprotein. The complex was present mostly as a dimer as determined by T2 relaxation measurements. The TRNOE crosspeaks in the ternary complex were assigned to the specific Tyr protons in the CCR5 peptide and to methyl protons, predominantly of isoleucine residues, and also of leucine and/or valine residues of gp120. The TRNOE/asymmetric deuteration method benefits from the sensitivity of the homonuclear NOESY experiment and does not suffer the sensitivity losses associated with isotope-edited/isotope-filtered approaches that rely on magnetization transfer between protons and heteronuclei that are bonded to them. The technique can be widely applied for studying large protein complexes that exhibit fast off-rates. PMID- 27701821 TI - Diffusion-weighted magnetic resonance imaging for residual and recurrent cholesteatoma: a systematic review and meta-analysis. AB - BACKGROUND: Diagnosis and management of recurrent or residual cholesteatoma can be problematic. Diffusion-weighted imaging magnetic resonance imaging (MRI) sequences have been used for follow-up of such lesions. More recent non echoplanar imaging (non-EPI) sequences are thought to be superior to older echoplanar imaging (EPI) sequences. OBJECTIVE OF REVIEW: Evaluate whether diffusion-weighted magnetic resonance imaging is useful in the diagnosis of recurrent or residual cholesteatoma. TYPE OF REVIEW: Systematic review and meta analysis. SEARCH STRATEGY: MEDLINE, EMBASE, CINAHL, Web of Science and the Cochrane Database were searched, with no limits on date or language. STUDY SELECTION: Adults or children who had previously undergone tympanomastoid surgery by any method with confirmation of recurrence/residual disease by second look/revision surgery. EVALUATION METHODS: Two reviewers independently reviewed studies. Data extracted on 11 domains and rechecked. DATA SYNTHESIS: Statistical analysis with SPSS. RESULTS: A total of 575 studies were identified of which 27 met the inclusion criteria. These covered 727 patient episodes. For EPI studies: sensitivity (sd) 71.82 (24.5), specificity (sd) 89.36 (13.4), PPV (sd) 93.36 (8.1) and NPV (sd) 73.36 (15.8). For non-EPI studies: sensitivity 89.79 (12.1), specificity (sd) 94.57 (5.8), PPV (sd) 96.50 (4.2) and NPV 80.46 (20.2). Improved sensitivity of non-EPI sequences reached significance (P = 0.02). CONCLUSIONS: Diffusion-weighted MRI is both sensitive and specific for the detection of recurrent or residual cholesteatoma following ear surgery. Non-EPI techniques are superior to EPI techniques. PMID- 27701822 TI - Long-term outcome for kaposiform hemangioendothelioma: A report of two cases. AB - Kaposiform hemangioendothelioma (KHE) is a rare aggressive vascular tumor of skin and deep soft tissues that typically presents in infancy and may be associated with a potentially life-threatening coagulopathy known as Kasabach-Merrit phenomenon (KMP). Recent advances in medical therapy have successfully treated many patients. However, our knowledge regarding the natural history of these lesions and optimum surveillance strategies remains rudimentary. We report two young women who had KHE with KMP treated in infancy and presented in adolescence with comorbidities related to their KHE tumor. This presentation supports the need for long-term surveillance in these patients. PMID- 27701823 TI - Differential proteomic analysis of the metabolic network of the marine sulfate reducer Desulfobacterium autotrophicum HRM2. AB - The marine sulfate-reducing bacterium Desulfobacterium autotrophicum HRM2 belongs to the deltaproteobacterial family Desulfobacteraceae and stands out for its capacity of facultative chemolithoautotrophic growth (next to heterotrophy). Here, proteomics-driven metabolic reconstruction was based on a combination of 2D DIGE, shotgun proteomics, and analysis of the membrane protein enriched fraction applied to eight different substrate adaptation conditions (seven aliphatic compounds plus H2 /CO2 ). In total, 1344 different proteins were identified (~27% of the 4947 genome-predicted), from which a complex metabolic network was reconstructed consisting of 136 proteins (124 detected; ~91%). Peripheral degradation routes for organic substrates feed directly or via the methylmalonyl CoA pathway into the Wood-Ljungdahl pathway (WLP) for terminal oxidation to CO2 . Chemolithoautotrophic growth apparently involves the periplasmic [Ni/Fe/Se] containing hydrogenase HysAB (H2 oxidation), the reductively operating WLP (CO2 fixation), and classical gluconeogenesis. Diverse soluble proteins (e.g., Hdr, Etf) probably establish a fine balanced cytoplasmic electron transfer network connecting individual catabolic reactions with the membrane menaquinone pool. In addition, multiple membrane protein complexes (Nqr, Qmo, Qrc, Rnf1, Rnf2, and Tmc) provide ample routes for interacting with the reducing equivalent pool and delivering electrons to dissimilatory sulfate reduction (both localized in the cytoplasm). Overall, this study contributes to the molecular understanding of the habitat-relevant Desulfobacteraceae. PMID- 27701824 TI - New horizons in geomycology.

PMID- 27701826 TI - In Vitro Topographical Model of Fuchs Dystrophy for Evaluation of Corneal Endothelial Cell Monolayer Formation. AB - A common indication for corneal transplantation, which is the most transplanted tissue, is a dysfunctional corneal endothelium due to Fuchs' endothelial dystrophy (FED). FED is diagnosed by the presence of in vivo pathological microtopography on the Descemet membrane, which is called corneal guttata. Minimally invasive corneal endothelial cell regenerative procedures such as endothelial cell injection therapy and Rho kinase inhibitor pharmacotherapy have been proposed as alternatives to conventional corneal transplantation for FED patients. However, the effect of guttata on monolayer reformation following such therapies is unknown and there is no equivalent in vitro or animal model to study monolayer reformation. Using a synthetic guttata FED disease model, the formation of the monolayer is investigated to evaluate the efficacy of both therapies. Results obtained suggest that guttata dimensions, density, and spacing greatly affect the fate of corneal endothelial cells in terms of migratory behavior and monolayer reformation. Densely packed synthetic guttata mimicking late-stage FED hinders monolayer reformation, while synthetic guttata of lower height and density show improved monolayer formation. These results suggest that severity of the FED, as determined by height and density of existing guttata, can potentially attenuate corneal endothelial monolayer formation of corneal cell injection therapy and pharmacotherapy.

PMID- 27701827 TI - Beneficial Effects of Co-Ultramicronized Palmitoylethanolamide/Luteolin in a Mouse Model of Autism and in a Case Report of Autism. AB - AIMS: Autism spectrum disorder (ASD) is a condition defined by social communication deficits and repetitive restrictive behaviors. Association of the fatty acid amide palmitoylethanolamide (PEA) with the flavonoid luteolin displays neuroprotective and antiinflammatory actions in different models of central nervous system pathologies. We hypothesized that association of PEA with luteolin might have therapeutic utility in ASD, and we employed a well-recognized autism animal model, namely sodium valproate administration, to evaluate cognitive and motor deficits. METHODS: Two sets of experiments were conducted. In the first, we investigated the effect of association of ultramicronized PEA with luteolin, co ultramicronized PEA-LUT(r) (co-ultraPEA-LUT(r)) in a murine model of autistic behaviors, while in the second, the effect of co-ultraPEA-LUT(r) in a patient affected by ASD was examined. RESULTS: Co-ultraPEA-LUT(r) treatment ameliorated social and nonsocial behaviors in valproic acid-induced autistic mice and improved clinical picture with reduction in stereotypes in a 10-year-old male child. CONCLUSION: These data suggest that ASD symptomatology may be improved by agents documented to control activation of mast cells and microglia. Co-ultraPEA LUT(r) might be a valid and safe therapy for the symptoms of ASD alone or in combination with other used drugs. PMID- 27701829 TI - The VHOT (Vindaloo Hastens Outpouring of Troponins) Study. AB - BACKGROUND: Multiple cardiac and non-cardiac processes may cause an elevated highly sensitive troponin (hsTn). We postulated that the consumption of a seriously hot vindaloo could cause an increase in hsTn levels in seemingly healthy volunteers. OBJECTIVE: To determine whether eating a very hot curry can cause elevated hsTn. METHODS: This was a prospective observational cohort study. Participants had blood drawn for hsTn pre-ingestion and at 2 and 4 h post ingestion of, first, a rather mild butter chicken and, 2 weeks later, a seriously hot lamb vindaloo. We assessed pre-curry tolerance and perception of curry hotness for both curries using the VHOT scale. RESULTS: Although no participant had a troponin above the reference range at any point in time, we found dramatic relative increases in troponin in many of our participants. In the vindaloo phase, 8/22 (36%) had a relative change >20%, whereas 5/22 (23%) had a relative change >50% at 4 h. However, these changes were not significantly different to those in the butter chicken phase. Based on biological variability alone, 15/22 (68%) had a relative change of >20%, and 11/22 (50%) had a relative change of >50% between the two sessions (pre-ingestion). CONCLUSIONS: Eating a seriously hot vindaloo does not appear to be a risk factor for troponitis, and people may consume vindaloo safely with the knowledge that this is unlikely to result in significant damage to their myocardium. However, clinicians should be aware of the biological variability of hsTn and exercise caution when interpreting apparent changes within the normal range. PMID- 27701830 TI - Growth of magnetotactic sulfate-reducing bacteria in oxygen concentration gradient medium. AB - Although dissimilatory sulfate-reducing bacteria (SRB) are generally described as strictly anaerobic organisms with regard to growth, several reports have shown that some SRB, particularly Desulfovibrio species, are quite resistant to O2 . For example, SRB remain viable in many aerobic environments while some even reduce O2 to H2 O. However, reproducible aerobic growth of SRB has not been unequivocally documented. Desulfovibrio magneticus is a SRB that is also a magnetotactic bacterium (MTB). MTB biomineralize magnetosomes which are intracellular, membrane-bounded, magnetic iron mineral crystals. The ability of D. magneticus to grow aerobically in several different media under air where an O2 concentration gradient formed, or under O2 -free N2 gas was tested. Under air, cells grew as a microaerophilic band of cells at the oxic-anoxic interface in media lacking sulfate. These results show that D. magneticus is capable of aerobic growth with O2 as a terminal electron acceptor. This is the first report of consistent, reproducible aerobic growth of SRB. This finding is critical in determining important ecological roles SRB play in the environment. Interestingly, the crystal structure of the magnetite crystals of D. magneticus grown under microaerobic conditions showed significant differences compared with those produced anaerobically providing more evidence that environmental parameters influence magnetosome formation. PMID- 27701831 TI - Clinical outcomes of levalbuterol versus racemic albuterol in pediatric patients with asthma: Propensity score matching approach in a medicaid population. AB - OBJECTIVE: Racemic albuterol and levalbuterol are used to treat acute episodes of asthma. The main objective of this study was to compare levalbuterol therapy to albuterol therapy on incidence rates of subsequent emergency department (ED) visits and hospitalizations. METHOD: We conducted a retrospective cohort study of asthmatic children who had pharmacy refills for levalbuterol/albuterol in the South Carolina Medicaid database in 2002-2011. Children receiving levalbuterol were matched to those receiving albuterol using propensity score matching technique. For ED visits and separately for hospitalizations, multivariable negative binomial regression was used to estimate the two group-specific incidence rates and the incidence rate ratio (IRR). RESULTS: A total of 8,172 asthmatic patients aged 2-18 years were identified in the South Carolina Medicaid database. During the 12-month follow-up period, the levalbuterol group had fewer asthma-related ED visits and hospitalizations: 939 (11.49%) children had asthma related ED visits (levalbuterol: 8.76%; albuterol: 14.21%), and 89 (1.09%) children had asthma-related hospitalizations (levalbuterol: 1.07%; albuterol: 1.12%). Comparing the levalbuterol group to the albuterol group, the adjusted IRR estimate was 0.57 (95% confidence interval [CI], 0.49-0.65) for of asthma-related ED visits, and 0.93 (95%CI, 0.99-1.63) for hospitalizations. Children filling levalbuterol also had a lower IRR of all-cause ED visit (0.88; 95%CI, 0.82-0.95), but similar IRR of all-cause hospitalizations (1.08; 95%CI, 0.82-1.42). CONCLUSION: This observational study of children aged 2-18 demonstrated levalbuterol prescription fills were associated with reduced ED visits, but not hospitalizations. Additional research may be necessary to assess this association. Pediatr Pulmonol. 2017;52:516-523. (c) 2016 Wiley Periodicals, Inc. PMID- 27701832 TI - Medicine in small doses.

PMID- 27701843 TI - Expression of the diguanylate cyclase GcbA is regulated by FleQ in response to cyclic di-GMP in Pseudomonas putida KT2440. AB - Cyclic di-GMP (c-di-GMP), a ubiquitous bacterial second messenger that regulates diverse cellular processes, is synthesized by diguanylate cyclase (DGC) and degraded by phosphodiesterase (PDE). GcbA is a well conserved DGC among Pseudomonas species, and has been reported to influence biofilm formation and flagellar motility in Pseudomonas fluorescens and Pseudomonas aeruginosa. Here we confirm the function of GcbA in Pseudomonas putida and reveal that expression of GcbA is regulated by FleQ in response to c-di-GMP. GcbA deletion impaired initial biofilm formation and enhanced swimming motility, but showed no influence on biofilm maturation in Pseudomonas putida. Deletion of the c-di-GMP effector FleQ led to a significant decrease in transcription of gcbA. Moreover, reducing c-di GMP levels promoted gcbA transcription in a FleQ dependent way, while enhancing c di-GMP levels abolished the promotion. In in vitro experiments we found that FleQ bound to gcbA promoter DNA and the binding was inhibited by c-di-GMP. Besides, FleN, an anti-activator of FleQ, and the sigma factor RpoN also participated in transcription of gcbA. Our finding expands the complexity of FleQ-dependent regulation and reveals a self-regulation function of c-di-GMP by regulating GcbA expression via FleQ. PMID- 27701844 TI - Generation of accurate peptide retention data for targeted and data independent quantitative LC-MS analysis: Chromatographic lessons in proteomics. AB - The emergence of data-independent quantitative LC-MS/MS analysis protocols further highlights the importance of high-quality reproducible chromatographic procedures. Knowing, controlling and being able to predict the effect of multiple factors that alter peptide RP-HPLC separation selectivity is critical for successful data collection for the construction of ion libraries. Proteomic researchers have often regarded RP-HPLC as a "black box", while vast amount of research on peptide separation is readily available. In addition to obvious parameters, such as the type of ion-pairing modifier, stationary phase and column temperature, we describe the "mysterious" effects of gradient slope, column size and flow rate on peptide separation selectivity. Retention time variations due to these parameters are governed by the linear solvent strength (LSS) theory on a peptide level by the value of its slope S in the basic LSS equation-a parameter that can be accurately predicted. Thus, the application of shallower gradients, higher flow rates, or smaller columns will each increases the relative retention of peptides with higher S-values (long species with multiple positively charged groups). Simultaneous changes to these parameters that each drive shifts in separation selectivity in the same direction should be avoided. The unification of terminology represents another pressing issue in this field of applied proteomics that should be addressed to facilitate further progress. PMID- 27701845 TI - End-of-life issues: Withdrawal and withholding of life-sustaining healthcare in the emergency department: A comparison between emergency physicians and emergency registrars: A sub-study. AB - OBJECTIVE: We investigated and compared the importance of the considerations and discussions when withdrawing and withholding life-sustaining healthcare between emergency physicians (EP) and emergency registrars (ER). METHODS: This was a sub study of a prospective cross-sectional questionnaire-based case series conducted in six EDs. Primary outcomes were, which of the discussion and considerations, were rated most important by EP and ER in the decision-making process. RESULTS: We studied responses relating to the care of 320 patients, of which 49.4% were women and the median age was 83 (interquartile range [IQR] 72-88). EP and ER were sole decision-makers in 185 (39.7%) and 135 (30.0%) of cases, respectively. Treatment was withdrawn or withheld in 72.0 and 90.6% of all deaths by EP and ER, respectively (P < 0.001). EP and ER provided full treatment in 88 (34%) and 19 (12.7%) of cases, respectively (P < 0.05). The consideration rated most important was prognosis: 165 (90.2%, confidence interval: 85.0-93.7) and 121 (90.3%, confidence interval: 84.1-94.2) for EP and ER, respectively. ER rated co morbidities and age more important than did EP (P < 0.05). Both rated discussions with family as very important. EP and ER referred 6.0% versus 11.9% patients to palliative care services, respectively. The proportion of patients taking longer than 24 h to die was higher for ER compared with that for EP (14.1% vs 4.9%, P < 0.05). CONCLUSION: We found that ER were more likely to withdraw/withhold life sustaining healthcare, provide partial treatment, rate different considerations as important and their patients took longer to die than that of EP. Focused education and training might improve decision-making consistency between physicians and training registrars. PMID- 27701846 TI - Genetic and Phytochemical Analysis to Evaluate the Diversity and Relationships of Mate (Ilex paraguariensis A.St.-Hil.) Elite Genetic Resources in a Germplasm Collection. AB - The aim of this study was to evaluate the phytochemical and genetic diversity, relationships and identification of mate (Ilex paraguariensis A.St.-Hil.) elite genetic resources belonging to the Brazilian germplasm collection and mate breeding program. Mate has been studied due to the presence of phytochemical compounds, especially methylxanthines and phenolic compounds. The samples were collected from the leaves of 76 mate elite genetic resources (16 progenies * 5 localities). Total DNA was extracted from mate leaves and 20 random primers were used for DNA amplification. Methylxanthines (caffeine and theobromine) and phenolic compounds (chlorogenic, neochlorogenic, and criptochlorogenic acids) were quantified by HPLC. The genetic divergence estimated was higher within (92%) than among (8%) the different populations. Analysis of genetic distance between origins provided the formation of two groups by UPGMA cluster analysis, with higher polymorphism (94.9%). The average content of caffeine ranged from 0.01 to 1.38% and theobromine of 0.10 - 0.85% (w/w). The caffeoylquinic acids concentrations (1.43 - 5.38%) showed a gradient 3-CQA > 5-CQA > 4-CQA. The coefficient of genetic variation (CVg) was of low magnitude for all mono caffeoylquinics acids. Significant correlations (positive and negative) were observed between the phytochemical compounds. Genetic diversity analysis performed by RAPD markers showed a greater intra-populational diversity; genetic resources with low caffeine and higher theobromine content were identified and can be used in breeding programs; the correlation between methylxanthines and phenolic compounds can be used as a good predictor in future studies.

AB - OBJECTIVE: To determine the proportion of non-motorised road users involved in road traffic crashes that presents to hospital intoxicated. METHODS: We undertook a retrospective cohort study using data collected from the Alfred Trauma Registry. All patients presenting to an adult major trauma centre in Victoria, Australia from July 2009 to June 2014 who were involved in a road traffic crash as a non-motorised road user - pedestrians, pedal-cyclists, non-motorised scooter users, horse riders - were included. Patients who had a blood alcohol measurement were included, and intoxication was defined as a blood alcohol concentration >=0.05 g/100 mL. RESULTS: There were 1323 patients included for analysis with data on presenting blood alcohol concentration. Alcohol was detected in 248 (18.7%; 95% CI: 16.7-20.9) patients, whereas 211 (15.9%; 95% CI: 14.1-18.0) were intoxicated. Among all included pedestrians, 161 (24.7%) were intoxicated; among all included pedal-cyclists, 47 (7.3%) were intoxicated. Intoxicated patients were significantly younger, and a higher proportion were males and more likely to present after hours and on public holidays (P < 0.01). Survival to hospital discharge and inpatient rehabilitation requirements were similar among intoxicated and non-intoxicated patients. CONCLUSIONS: Intoxication was common among non-motorised road users, and the proportion of intoxicated patients in this subgroup appears unchanged over time despite public awareness programmes. The true burden of intoxication in non-motorised road users remains unknown because of a lack of routine testing. Legislation directed at testing for intoxication of non-motorised users and introduction of penalties should be considered to improve safety of all road users.

AB - Dynamic fluctuations in RNA structure enable conformational changes that are required for catalysis and recognition. In the hairpin ribozyme, the catalytically active structure is formed as an intricate tertiary interface between two RNA internal loops. Substantial alterations in the structure of each loop are observed upon interface formation, or docking. The very slow on-rate for this relatively tight interaction has led us to hypothesize a double conformational capture mechanism for RNA-RNA recognition. We used extensive molecular dynamics simulations to assess conformational sampling in the undocked form of the loop domain containing the scissile phosphate (loop A). We observed several major accessible conformations with distinctive patterns of hydrogen bonding and base stacking interactions in the active-site internal loop. Several important conformational features characteristic of the docked state were observed in well-populated substates, consistent with the kinetic sampling of docking-competent states by isolated loop A. Our observations suggest a hybrid or multistage binding mechanism, in which initial conformational selection of a docking-competent state is followed by induced-fit adjustment to an in-line, chemically reactive state only after formation of the initial complex with loop B.

AB - BACKGROUND: Epidemiologic studies have reported conflicting results on the relationship between short sleep duration and non-alcoholic fatty liver disease (NAFLD). There are no previous studies investigating the effect of daytime napping on NAFLD. In the present study we examined the associations between NAFLD and both nightly sleep duration and daytime napping in a middle-aged and elderly Chinese population. METHODS: This cross-sectional community-based population study was performed on 8559 individuals aged >=40 years. Sleep duration and the duration of daytime napping were self-reported using a standardized questionnaire; NAFLD was diagnosed by ultrasonography. RESULTS: In this study sample, the overall prevalence of NAFLD was 30.4%. There was an inverse association between sleep duration and the risk of prevalent NAFLD. In multivariate analysis, the odds ratios (ORs) and 95% confidence intervals (CIs) of prevalent NAFLD for decreasing sleep duration categories (>=9, 8.1-9, 7.1-8, 6.1-7, and <=6.1 h) were 1.00 (reference), 1.38 (1.13-1.70), 1.32 (1.08-1.61), 1.29 (1.04-1.60), and 1.66 (1.28-2.15), respectively (P trend = 0.0073). Compared with participants without a daytime napping habit, nap takers with a longer nap duration (>0.5 h) had an increased risk of prevalent NAFLD (OR 1.22; 95% CI 1.06-1.41). The associations of sleep duration and daytime napping duration with NAFLD were generally consistent across different categories of age and obesity, metabolic syndrome, and insulin resistance status. CONCLUSIONS: Short sleep duration and longer daytime napping were associated with an increased risk of prevalent NAFLD in a middle-aged and elderly Chinese population.

As mineral dust particles undergo long distance transport, they are exposed to trace gases and water vapor. We have characterized the interactions of acetic acid on kaolinite using Diffuse Reflectance Infrared Fourier Transform Spectroscopy and molecular modeling to determine the chemisorbed species present. After the addition of acetic acid, gas phase water was introduced to explore how water vapor competes with acetic acid for surface sites. We have found that four chemisorbed acetate species are found on kaolinite after exposure to acetic acid in which acetate bonds through a monodentate, bidenatate, or bidentate bridging linkage with an aluminum atom. These species exhibit varying levels of stability after the introduction of water, indicating that water vapor affects the adsorption of organic acids. These results indicate that the type of chemisorbed species determines its stability toward competitive adsorption, which has potential implications for atmospheric composition and ice nucleation.

AB - Thirty-six porphyrin based metal-organic frameworks (MOFs) with composition of (M3O)2(TCPP-M)3 and M3O trigonal SBUs of various metals, Mg3O, Mn3O, Co3O, Ni3O, and Fe3O including mixed-metal SBUs, MnxFe3-xO, NixFe3-xO, CoxNi3-xO, MnxCo3-xO, MnxMg3-xO, and MnxNi3-xO were synthesized and characterized. These multivariate MOFs (MTV-MOFs) were examined by X-ray photoelectron spectroscopy (XPS), ultraviolet-visible diffuse reflectance spectra (UV-vis DRS) and, for the first time, their metal spatial arrangement deciphered and found to exist in the form of either domains or well-mixed. We find that those MTV-MOFs with well-mixed metals in their SBUs, rather than the SBUs having one kind of metal but different from one SBU to another, perform better than the sum of their parts in the test reaction involving the photo-oxidation of 1,5-dihydroxynaphthalene (DHN) [for example, kobs = 1.03 h-1 for (Mn1.77Ni1.23O)2(TCPP-Ni)3]. PMID- 27701855 TI - Kinetics of Dimethylated Thioarsenicals and the Formation of Highly Toxic Dimethylmonothioarsinic Acid in Environment. AB - Dimethylmonothioarsinic acid (DMMTAV) is a highly toxic, thiolated analogue of dimethylarsinic acid (DMAV). In comparison, a further thiolated analogue, dimethyldithioarsinic acid (DMDTAV), and DMAV both exhibit lower toxicity. To understand the environmental conditions responsible for forming DMMTAV, the kinetics of DMAV thiolation are examined. The thiolation of DMAV is pH-dependent and consists of two consecutive first-order reactions under excess sulfide conditions. The first thiolation of DMAV to form DMMTAV is faster than the second one to DMDTAV. DMMTAV is therefore an intermediate. The first reaction is first order in H2S at pH 6.0 and 20 degrees C; therefore, the overall reaction is second-order and the rate coefficient in this condition is 0.0780 M-1 s-1. The rate coefficient significantly decreases at pH 8.0, indicating that H2S(aq) triggers the thiolation of DMAV. The second reaction rate is significantly decreased at pH 2.5; therefore, reaction under strongly acidic conditions leads to accumulation of highly toxic DMMTAV in the early stages of thiolation. The transformation of DMDTAV to DMMTAV is catalyzed in the presence of ferric iron. Formation of DMMTAV should be considered when assessing risk posed by arsenic under sulfidic or sulfate reducing conditions.

AB - This study aimed to investigate the protective effects of degraded soybean polysaccharides (DSP) on oxidatively damaged African green monkey kidney epithelial (Vero) cells. Low DSP concentration (10 MUg/mL) elicited an evident protective effect on H2O2-induced cell injury (0.3 mmol/L). The cell viabilities of the H2O2-treated group and the DSP-protected group were 57.3% and 93.1%, respectively. The cell viability decreased to 88.3% when the dosage was increased to 100 MUg/mL. DSP protected Vero cells from H2O2-mediated oxidative damage by enhancing cellular superoxide dismutase activity and total antioxidant capacity and by decreasing malonaldehyde content and lactate dehydrogenase release. The H2O2-treated cells stimulated the aggregation of calcium oxalate monohydrate crystals. DSP could also reduce the crystal size, decrease the attached crystal content, and prevent the cell aggregation by alleviating oxidative injury and lipid peroxidation, enhancing antioxidant capacity, and decreasing hyaluronan expression on cellular surfaces. The internalization ability of the injured cells was improved after these cells were exposed to DSP solution. The regulation ability of DSP-repaired cells on calcium oxalate dihydrate formation, crystal attachment, aggregation, and internalization was lower than that of normal cells but was higher than that of the injured cells. DSP may be a potential green drug to prevent CaOx stone formation because DSP could protect cells from oxidative damage and inhibit CaOx crystal formation.

AB - TiO2/g-C3N4 photocatalysts with the ratio of TiO2 to g-C3N4 ranging from 0.3/1 to 2/1 were prepared by simple mechanical mixing of pure g-C3N4 and commercial TiO2 Evonik P25. All the nanocomposites were characterized by X-ray powder diffraction, UV-vis diffuse reflectance spectroscopy, photoluminescence, X-ray photoelectron spectroscopy, Raman spectroscopy, infrared spectroscopy, transmission electron microscopy, photoelectrochemical measurements, and nitrogen physisorption. The prepared mixtures along with pure TiO2 and g-C3N4 were tested for the photocatalytic reduction of carbon dioxide and photocatalytic decomposition of nitrous oxide. The pure g-C3N4 exhibited the lowest photocatalytic activity in both cases, pointing to a very high recombination rate of charge carriers. On the other hand, the most active photocatalyst toward all the products was (0.3/1)TiO2/g-C3N4. The highest activity is achieved by combination of a number of factors: (i) specific surface area, (ii) adsorption edge energy, (iii) crystallite size, and (iv) efficient separation of the charge carriers, where the efficient charge separation is the most decisive parameter. PMID- 27701858 TI - Effect of Aging and PCBM Content on Bulk Heterojunction Organic Solar Cells Studied by Intensity Modulated Photocurrent Spectroscopy. AB - A series of encapsulated and nonencapsulated bulk heterojunction photovoltaic devices containing poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) with different P3HT:PCBM ratios were investigated using traditional steady-state as well as non-steady-state intensity modulated photocurrent spectroscopy (IMPS) techniques. The steady state J-V measurements showed that PCBM content did not have a significant effect on the efficiency for freshly prepared devices, whereas aged nonencapsulated devices exhibited a strong dependence on PCBM content. IMPS measurements showed a significant contribution of interfacial nongeminate recombination in nonencapsulated devices, which increased with decreasing PCBM content in the photoactive layer and cell aging. It was related to the formation of interfacial states at the P3HT/PCBM interface due to atmospheric contamination, which act as recombination centers. Device encapsulation was found to be effective in preventing the occurrence of interfacial recombination. Our results suggest that IMPS can be used as a diagnostic tool to predict the performance of bulk heterojunction organic solar cells. If a solar cell shows the presence of interfacial states as indicated by semicircle arcs in quadrant I of the IMPS complex plane plots, it is most likely that its performance will deteriorate with time due to enhanced interfacial recombination, even without further exposure to atmospheric contaminations. We conclude that interfacial nongeminate recombination is an important degradation mechanism in organic solar cells, especially in the case of exposure to atmospheric contaminants.

PMID- 27701861 TI - Photoemission of Energetic Hot Electrons Produced via Up-Conversion in Doped Quantum Dots. AB - The benefits of the hot electrons from semiconductor nanostructures in photocatalysis or photovoltaics result from their higher energy compared to that of the band-edge electrons facilitating the electron-transfer process. The production of high-energy hot electrons usually requires short-wavelength UV or intense multiphoton visible excitation. Here, we show that highly energetic hot electrons capable of above-threshold ionization are produced via exciton-to-hot carrier up-conversion in Mn-doped quantum dots under weak band gap excitation (~10 W/cm2) achievable with the concentrated solar radiation. The energy of hot electrons is as high as ~0.4 eV above the vacuum level, much greater than those observed in other semiconductor or plasmonic metal nanostructures, which are capable of performing energetically and kinetically more-challenging electron transfer. Furthermore, the prospect of generating solvated electron is unique for the energetic hot electrons from up-conversion, which can open a new door for long-range electron transfer beyond short-range interfacial electron transfer.

AB - HIV-1 CA capsid protein possesses intrinsic conformational flexibility, which is essential for its assembly into conical capsids and interactions with host factors. CA is dynamic in the assembled capsid, and residues in functionally important regions of the protein undergo motions spanning many decades of timescales. Chemical shift anisotropy (CSA) tensors, recorded in magic-angle spinning NMR experiments, provide direct residue-specific probes of motions on nano- to microsecond timescales. We combined NMR, MD, and Density-Functional Theory calculations, to gain quantitative understanding of internal backbone dynamics in CA assemblies, and found that the dynamically averaged 15N CSA tensors calculated by this joined protocol are in remarkable agreement with experiment. Thus, quantitative atomic-level understanding of the relationships between CSA tensors, local backbone structure and motions in CA assemblies is achieved, demonstrating the power of integrating NMR experimental data and theory for characterizing atomic-resolution dynamics in biological systems.

AB - Cu nanowires (Copper nanowires) have attracted lots of attention recently due to their potential applications in transparent electrodes, surface enhanced Raman scattering (SERS) based sensors, and solar cells. However, as the surface composition and morphology of Cu nanowires severely influence the performance of the devices based on them, facile surface modification methods need to be developed. Herein, we propose a room-temperature, time-saving aqueous solution method, through which clean Cu nanowires with small Ag nanoparticles decorating around them could be achieved. The unique "sesame candy bar" structure of Cu nanowires brought about significant enhancement on the electrical, optical, and mechanical performances of Cu nanowire networks. Transparent electrodes with ideal opto-electrical performance (47 Omega sq-1 @ 89.1% T) and high antioxidation, antithermal, and electrical stability were fabricated. Stretchable electrodes based on the modified Cu nanowire networks showed superior stretch ability and cyclic stability. SERS sensors and organic solar cells based on Cu nanowire networks exhibited high performance due to the enhanced surface plasmonic coupling and light scattering effect. We believe that the method will shed light on the large-scale fabrication and application of Cu nanowire based devices. PMID- 27701863 TI - Laser Level Scheme of Self-Interstitials in Epitaxial Ge Dots Encapsulated in Si. AB - Recently, it was shown that lasing from epitaxial Ge quantum dots (QDs) on Si substrates can be obtained if they are partially amorphized by Ge ion bombardment (GIB). Here, we present a model for the microscopic origin of the radiative transitions leading to enhanced photoluminescence (PL) from such GIB-QDs. We provide an energy level scheme for GIB-QDs in a crystalline Si matrix that is based on atomistic modeling with Monte Carlo (MC) analysis and density functional theory (DFT). The level scheme is consistent with a broad variety of PL experiments performed on as-grown and annealed GIB-QDs. Our results show that an extended point defect consisting of a split-[110] self-interstitial surrounded by a distorted crystal lattice of about 45 atoms leads to electronic states at the Gamma-point of the Brillouin zone well below the conduction band minimum of crystalline Ge. Such defects in Ge QDs allow direct transitions of electrons localized at the split-interstitial with holes confined in the Ge QD. We identify the relevant growth and annealing parameters that will let GIB-QDs be employed as an efficient laser active medium.

AB - Despite their various potential applications, InAs colloidal quantum dots have attracted considerably less attention than more classical II-VI materials because of their complex syntheses that require hazardous precursors. Recently, amino phosphine has been introduced as a cheap, easy-to-use and efficient phosphorus precursor to synthesize InP quantum dots. Here, we use aminopnictogen precursors to implement a similar approach for synthesizing InAs quantum dots. We develop a two-step method based on the combination of aminoarsine as the arsenic precursor and aminophosphine as the reducing agent. This results in state-of-the-art InAs quantum dots with respect to the size dispersion and band-gap range. Moreover, we present shell coating procedures that lead to the formation of InAs/ZnS(e) core/shell quantum dots that emit in the infrared region. This innovative synthesis approach can greatly facilitate the research on InAs quantum dots and may lead to synthesis protocols for a wide range of III-V quantum dots.

AB - Compartmentalization in soft matter is important for segregating and coordinating chemical reactions, sequestering (re)active components, and integrating multifunctionality. Advances depend crucially on quantitative 3D visualization in situ with high spatiotemporal resolution. Here, we show the direct visualization of different compartments within adaptive microgels using a combination of in situ electron and super-resolved fluorescence microscopy. We unravel new levels of structural details and address the challenge of reconstructing 3D information from 2D projections for nonuniform soft matter as opposed to monodisperse proteins. Moreover, we visualize the thermally induced shrinkage of responsive core-shell microgels live in water. This strategy opens doors for systematic in situ studies of soft matter systems and their application as smart materials. PMID- 27701866 TI - Elasticity, adhesion and tether extrusion on breast cancer cells provide a signature of their invasive potential. AB - We use single cell force spectroscopy to compare elasticity, adhesion and tether extrusion on four breast cancer cell lines with an increasing invasive potential. We perform cell attachment/detachment experiments either on fibronectin or on another cell using an Atomic Force Microscope. Our study on the membrane tether formation from cancer cells show that they are easier to extrude from aggressive invasive cells. Measured elastic modulus values confirm that more invasive cells are softer. Moreover, the adhesion force increases with the invasive potential. Our results provide a mechanical signature of breast cancer cells that correlates with their invasivity. PMID- 27701867 TI - Approach Based on Polyelectrolyte-Induced Nanoassemblies for Enhancing Sensitivity of Pyrenyl Probes. AB - We have developed a unique approach for enhancing the sensitivity of pyrenyl probes based on polyelectrolyte-induced nanoassemblies and explored its sensing application toward 2,4,6-trinitrophenol (TNP). The key issue of the method is the formation of the nanoassemblies which possess high-density charges, specific surface area, and inner hydrophobic regions. These properties would help increase the loading of analytes and promote probe-analyte interactions, thereby leading to the prominent enhancement of the sensitivity. In the course of TNP detection, pyrene nanoassemblies can bind TNP efficiently through cooperative noncovalent interactions including electrostatic, pi-pi stacking, and charge-transfer interactions, resulting in the distinct fluorescent responses of pyrene moieties. This system has excellent selectivity and sensitivity for TNP detection. The detection limit is as low as 5 nM. It may be used for monitoring the TNP concentrations in real-world samples.

AB - The pursuit of harmonic combination of technology and fashion intrinsically points to the development of smart garments. Herein, we present an all-solid tailorable energy textile possessing integrated function of simultaneous solar energy harvesting and storage, and we call it tailorable textile device. Our technique makes it possible to tailor the multifunctional textile into any designed shape without impairing its performance and produce stylish smart energy garments for wearable self-powering system with enhanced user experience and more room for fashion design. The "threads" (fiber electrodes) featuring tailorability and knittability can be large-scale fabricated and then woven into energy textiles. The fiber supercapacitor with merits of tailorability, ultrafast charging capability, and ultrahigh bending-resistance is used as the energy storage module, while an all-solid dye-sensitized solar cell textile is used as the solar energy harvesting module. Our textile sample can be fully charged to 1.2 V in 17 s by self-harvesting solar energy and fully discharged in 78 s at a discharge current density of 0.1 mA.

AB - We report the synthesis and characterization of a water-stable zirconium metal organic framework (MOF), NU-1003, featuring the largest mesoporous aperture known for a zirconium MOF. This material has been used to immobilize the nerve agent hydrolyzing enzyme, organophosphorus acid anhydrolase (OPAA). The catalytic efficiency of immobilized OPAA in nanosized NU-1003 is significantly increased compared to that of OPAA immobilized in microsized NU-1003 and even exceeds that of the free OPAA enzyme. This paper highlights a method for rapid and highly efficient hydrolysis of nerve agents using nanosized enzyme carriers.

AB - Lifestyle and family history are two of the most important risk factors for breast cancer (BC). However, these risk factors cannot explain the differences in the incidence and early BC onset among Chinese females compared to their western counterparts. We propose in this hypothesis the potential mechanism of indirect oncogenesis of hepatitis B virus (HBV) in causing BC through its persistence as occult infection and continuous replication with long term subtle liver damage. Estrogen is mainly deactivated in the liver and long term necro-inflammatory damage to liver may result in persistent high level of estrogen, which is a dominant risk factor for BC. HBV may also directly affect the breast cells through its cis and trans effects of HBx which may act as oncoprotein. Given the recognised aetiologic association between oestrogen and breast cancer risk, there is biological plausibility that dietary soy and vegetable intake which is rich in the Chinese diet may have anti-carcinogenic effect on the breast. The seemingly conflicting phenomenon of early age onset and lower BC incidence in China might be due to wide imbalance in the amount of exposure to carcinogenic factor (e.g., HBV infection) for decades and the carcinoprotective exposure levels (e.g., isoflavonoids and flavonoids intake). For example, the increase in carcinoprotective levels would lead to lower incidence of breast cancer and vice versa. Although the focus of this personal view is on HBV, this by no means negates the roles of other known risk factors in breast-cancer development. Characterisation of the role of HBV in BC could potentially benefit Chinese females by decreasing incidence and increasing overall survival. PMID- 27701873 TI - Adjuvant therapy for resected biliary tract cancer: a review. AB - Surgical resection remains the most important treatment for patients with biliary tract cancer (BTC), but despite radical surgical techniques many patients ultimately develop recurrent disease. BTC encompasses several distinct disease entities-intrahepatic, perihilar and distal bile duct cholangiocarcinoma as well as gallbladder cancer. These tumors are histologically similar, but have different etiologies and recent information regarding their genomic footprint has questioned their biological similarity. Surgical approaches are also necessarily varied based on the site of the tumor. Due to the poor survival rates seen in this disease, there has been significant effort to investigate chemotherapy and radiotherapy as adjuvants in patients whose disease has been successfully resected. The majority of the published evidence supporting this treatment relies on retrospective series or limited prospective studies, making interpretation difficult and complicating treatment decisions. This review summarizes the data regarding these adjunctive therapies. PMID- 27701874 TI - Initial assessment of patients without cognitive failure admitted to palliative care: a validation study. AB - OBJECTIVE: Many assessment tools have been developed for palliative care and there are a number of differences between them. Therefore, we felt that there was room for improvement. METHODS: In a previous study, the relevant items were selected by a Delphi process with international experts in palliative care. A 5 point verbal scale was added to the items selected and adapted to the different kind of items. RESULTS: The study included 123 patients, 63 (51%) were female and the median age was 64 (37 to 88). A four-factor structure was found through the principal components analysis, explaining 60.1% of the total variance. The scale presented good reliability, with a Cronbach's alpha of 0.72. It was hypothesized as a validity of construct that as the total symptom burden increased, survival time would decrease. This hypothesis was confirmed by the statistical analysis performed. A hazard ratio of 1.016 (P=0.019) was obtained in the Cox regression model including the final score as an explanatory variable of survival time, which means that for each increment of 1% in the total score, there was an increased risk of death of 1.6%. CONCLUSIONS: This tool is in accordance with the recommended characteristics that an assessment tool should have. It is simple to administer and easy to explain, complete and analyze. It is also a valid tool. PMID- 27701876 TI - Radiation therapy for the treatment of skin Kaposi sarcoma. AB - OBJECTIVE: Kaposi sarcoma (KS) lesions are purplish, reddish blue or dark brown/black macules, plaques or nodules which involve the skin and occasionally internal organs. Most patients with KS have a long indolent chronic course. METHODS: A retrospective review was undertaken for all KS skin patients treated with radiotherapy at a tertiary cancer centre from Jan. 2, 1999 to Dec. 31, 2014 (inclusive). RESULTS: A total of 47 patients with KS (43 classical, 0 African, 1 iatrogenic, 3 AIDS related) were seen in the multidisciplinary clinic. Out of this group, 17 patients (5 females and 12 males, 14 classical, 0 African, 0 iatrogenic, 3 AIDS related) with 97 KS skin sites were treated with local external beam radiotherapy. An additional 18 skin sites were treated with repeat radiotherapy. The radiotherapy dose ranged from 6 Gy in 1 fraction to 30 Gy in 10 fractions with the most common dose fractionation scheme being 8 Gy in 1 fraction or 20 Gy in 5 daily fractions. For the previously untreated KS sites, 87% responded to radiation [30% complete response (CR) and 57% partial response (PR)]. Thirteen percent of KS sites treated with radiation progressed. For the skin sites which were treated with repeat radiotherapy, 0% showed CRs, 50% PRs and 50% had continued progression. CONCLUSIONS: The majority of KS skin lesions (87%) responded to radiotherapy. Patients experience minimal side effects from the palliative radiation regimens used. KS skin lesions which progress despite radiation are unlikely to show CR with repeat radiotherapy. In our experience 50% of skin KS will have partial regression with repeat radiotherapy and 50% will have continued progression. PMID- 27701875 TI - Possible role of aprepitant for intractable nausea and vomiting following whole brain radiotherapy-a case report. AB - Radiation-induced nausea and vomiting (RINV) is one of the most distressing symptoms that adversely affects quality of life (QOL) as well as the ongoing management plan of cancer patients. Although there are protocols for management of chemotherapy induced nausea and vomiting (CINV) but such guidelines are still lacking for RINV. Various agents like 5-hydroxy tryptophan 3 (5-HT3) antagonist, dexamethasone, metoclopramide and haloperidol are used in clinical practice for RINV but the results are not very encouraging. Because of proposed similarity in the mechanism of nausea and vomiting following chemotherapy and radiotherapy, aprepitant, a substance P neurokinin 1 receptor antagonist can be an optimal agent for RINV on account of its unique pharmacological property. We report a case of metastatic carcinoma breast with bilateral cerebellar metastasis. She presented with complaints of headache and intractable nausea and vomiting. A single fraction whole brain radiotherapy (WBRT) was given for bilateral cerebellum metastasis which further precipitated her symptoms. The prophylactic and therapeutic efficacy of antiemetic used for RINV may be enhanced by adding aprepitant before starting radiotherapy in high risk cases as in ours. PMID- 27701877 TI - Is the French palliative care policy effective everywhere? Geographic variation in changes in inpatient death rates among older patients in France, 2010-2013. AB - OBJECTIVE: Recently, French policymakers have tried to improve care at the end-of life, by improving access to community-based palliative care, particularly for patients with cancer and neurological diseases. If effective, these efforts should reduce the proportion of such patients who die in the hospital. In light of these policies, we sought to determine the effectiveness of these efforts on reducing inpatient deaths by conducting a retrospective, observational analysis of patients aged 65 and older who were admitted to hospitals in France between 2010 and 2013 for 1 of 3 non-surgical conditions. METHODS: We calculated department-specific age- and sex-adjusted inpatient death rates for 3 types of nonsurgical admissions and modeled expected number of inpatient deaths had their rates for patients with cancer or neurological disease tracked those of patients with non-cancer non-neurological diseases. RESULTS: We found that patients admitted with a cancer diagnosis experienced 20,394 (13.0%) fewer inpatient deaths that expected had non-surgical cancer diagnosis admission rates tracked those of nonsurgical non-cancer and non-neurological admission rates; patients admitted with a primary neurological disease diagnosis experienced 513 (4.5%) fewer inpatient deaths than expected. During the study period, observed-to expected inpatient deaths fell more dramatically and consistently for patients admitted with cancer diagnoses than for those admitted with neurological diseases. Observed-to-expected ratios fell least in departments that were on the periphery of the French mainland. CONCLUSIONS: Our findings suggest that, in France, efforts to reduce inpatient death rates among patients with cancer or neurological disease diagnoses appear to be effective. However, their effectiveness varies geographically, suggesting that targeted efforts to improve lower performing departments may generate substantial performance improvements. PMID- 27701878 TI - Radiotherapy for brain metastases: quo vadis? PMID- 27701879 TI - Correlating symptoms and their changes with survival in patients with brain metastases. AB - OBJECTIVE: Having a clear prognosis for patients with brain metastases allows health care practitioners (HCPs) to determine appropriate palliative management and assist patients when making informed treatment decisions. The objective of this study was to determine the prognostic significance of commonly experienced symptoms as well as their changes. METHODS: Overall survival (OS) was calculated from the date of consultation for palliative radiotherapy to date of death or censored at last follow-up date. Symptom changes at follow up were defined as worsened, improved, or no change. Univariate and multivariate cox proportional hazard (PH) model of OS was conducted on 14 symptoms at baseline and on changes in those symptoms at 1-, 2-, and 3-month follow-ups. RESULTS: From 1999 to 2013, 1,660 patients were included for baseline symptom analysis. Through univariate analysis, fatigue, nausea, appetite loss, coordination, concentration, balance and depression were significantly related to OS. Upon multivariate analysis, fatigue and appetite loss were most predictive of short survival. For symptom change, 201 patients were included. The actuarial median OS was 5.0 months [95% confidence interval (CI): 4.3-7.0], 7.1 months (95% CI: 5.2-9.5) and 8.8 months (95% CI: 5.8-11.5) for patients with month 1, 2, and 3 follow-ups, respectively. The most common symptom changes following whole brain radiotherapy (WBRT) were: worsened fatigue, appetite loss, and weakness. Worsened difficulty concentrating, fatigue, nausea and headaches were most predictive of a poorer survival outcome. CONCLUSIONS: HCPs should be aware of the shorter prognosis associated with patients exhibiting one or more of these symptoms and tailor care accordingly to maximize patients' remaining quality of life (QOL). PMID- 27701880 TI - Palliative care units in lung cancer in the real-world setting: a single institution's experience and its implications. AB - OBJECTIVE: Palliative care plays a crucial role in the overall management of patients with advanced lung cancer and was shown to lead to clinically meaningful improvement in quality of life, less aggressive endof-life care, and potentially prolonged survival. Here we summarize our single institution experience on palliative care in patients with lung cancer. METHODS: The data of patients with lung cancer treated at the palliative care unit of the Medical University of Vienna between June 2010 and March 2013 were retrospectively reviewed. Patient characteristics, reasons for admissions, treatment as well as interventions during hospitalization, and clinical outcomes were determined. RESULTS: The study enrolled 91 lung cancer patients, who represented 19.8% of the 460 patients admitted to the palliative care unit. They had the following clinical characteristics: 39% females, 61% males; median age 62 years; median Karnofsky performance status 50%, 92% metastatic disease, 74% non-small cell lung cancer (NSCLC), 19% small-cell lung cancer (SCLC), 7% neuroendocrine carcinomas of the lung. Primary reasons for admission were deterioration of performance status in 40%, uncontrolled cancer-related pain in 38%, dyspnea in 13%, and psychosocial factors in 8% of the patients. Median duration of hospitalization was 16 days (range, 1-101 days). Improvement or stabilisation of tumor-related symptoms was achieved in 25% of the patients. Seventy-five percent of all patients died during their first admission. Their median survival from primary diagnosis until death was 16 months (95% confidence interval, 13.7-18.3 months). CONCLUSIONS: Patients with lung cancer admitted to the palliative care unit had late-stage disease. In order to provide early palliative care, the management of lung cancer patients should guarantee access to ambulatory care, inpatient care and home care as well as cooperation and communication between oncologists and palliative care physicians. PMID- 27701881 TI - The use of a segmental endoscopic score may improve the prediction of clinical outcomes in acute severe ulcerative colitis. AB - BACKGROUND: Acute severe colitis (ASC) remains a challenging complication of ulcerative colitis. The early identification of patients who will not respond to optimal therapy is warranted. Increasing evidence suggests that endoscopy may play a role in predicting important outcomes in acute severe colitis. METHODS: The endoscopic activity of consecutive patients with acute severe colitis was evaluated using the Mayo endoscopic sub-score (Mayo) and the ulcerative colitis endoscopic index of severity (UCEIS). Two segmental indexes were also produced by summing the scores of the rectum and sigmoid (seg-Mayo and seg-UCEIS, respectively). Endpoints included the need for salvage therapy with infliximab or cyclosporine, refractoriness to corticosteroids, and colectomy. RESULTS: Of one hundred and eight patients enrolled in the study, 60 (55.6%) were male; with a median age of 34.5 years (range 15-80). All patients received intravenous steroids. Fifty-nine patients (55.6%) showed an incomplete or absent response to steroids, 35 patients (34.3%) received salvage therapy with infliximab or cyclosporine and 38 patients (33.3%) were colectomized during the index hospitalization or within the first year of follow-up. All scores were able to predict the need for surgery, but only the seg-UCEIS significantly predicted refractoriness to steroids. CONCLUSIONS: There was a strong correlation between endoscopic severity and unfavorable outcomes. The UCEIS outperformed the Mayo endoscopic sub-score in all important outcomes. Segmental scoring further improved the performance of the UCEIS. PMID- 27701882 TI - A single institution's 21-year experience with surgically resected pancreatic neuroendocrine tumors: an analysis of survival and prognostic factors. AB - BACKGROUND: Pancreatic neuroendocrine tumors (pNETs) comprise a heterogeneous group of tumors with a varied biological behavior. In the present study, we analyzed the experience of 79 pNETs resected between 1999 and 2014. The pathologic prognostic factors (European Neuroendocrine Tumor Society, ENETS; and AJCC) classification, vascular invasion (VI), proliferation index (ki-67) and the presence of necrosis were retrospectively reviewed. METHODS: The clinical data of 79 patients with pNETs who underwent surgery were retrospectively analyzed. Mortality rates and Kaplan-Meier estimates were used to evaluate survival over time for pathologic stages, tumor functionality, and vascular invasion. Cox proportional hazards models were used to calculate the hazard ratio regarding ENETS, AJCC staging, sex, tumor functionality and vascular invasion. RESULTS: The male:female ratio was 40:39. Twenty-one patients (26%) had functional tumors and 58 (73.4%) had non-functional tumors, of which 35 (44.3%) were diagnosed incidentally. Seventeen Whipple procedures, 46 distal pancreatectomies (including 26 laparoscopic and 20 open procedures), 8 laparoscopic central pancreatectomies, 1 laparoscopic resection of the uncinated process and 7 enucleations (one laparoscopic) were performed. Vascular invasion and necrosis were observed in 29 of 75 cases (38.6%) and in 16 cases (29%), respectively. The comparison between survivor functions of ENETS staging categories showed statistically significant differences (p = 0.042). Mortality rate was higher in patients with non functioning tumors compared with hormonally functioning tumors (p = 0.052) and in those with vascular invasion (p = 0.186). CONCLUSIONS: In spite of the heterogeneity of pNETs, the ENETS TNM classification efficiently predicts long term prognosis. The non-functioning tumors and the presence of vascular invasion are associated with poor prognosis. PMID- 27701883 TI - Validation of the computed assessment of cleansing score with the Mirocam(r) system. AB - BACKGROUND AND AIMS: A computed assessment of cleansing (CAC) score was developed to objectively evaluate small-bowel cleansing in the PillCam(r) capsule endoscopy (CE) system and to overcome the subjectivity and complexity of previous scoring systems. Our study aimed to adapt the CAC score to the Mirocam(r) system, evaluate its reliability with the Mirocam(r) CE system and compare it with three validated subjective grading scales. PATIENTS AND METHODS: Thirty CE were prospectively and independently reviewed by two authors who classified the degree of small-bowel cleanliness according to a quantitative index, a qualitative evaluation and an overall adequacy assessment. The authors were blinded for the CAC score of each CE, which was calculated as ([mean intensity of the red channel]/[mean intensity of the green channel] - 1) x 10. The mean intensities of the red and green channels of the small-bowel segment of the "Map View" bar in the Miroview Client(r) were determined using the histogram option of two photo editing software. RESULTS: There was a strong agreement between both CE readers for each of the three subjective scales used. The reproducibility of the CAC score was excellent and identical results were obtained with the two photo editing software. Regarding the comparison between the CAC score and the subjective scales, there was a moderate-to-good agreement with the quantitative index, qualitative evaluation and overall adequacy assessment. CONCLUSIONS: CAC score represents an objective and feasible score in the assessment of small-bowel cleansing in the Mirocam(r) CE system, and could be used per se or as part of a more comprehensive score. PMID- 27701884 TI - Ultrasound-assisted technique for challenging jejunostomy balloon-tube replacements. AB - The authors present a case of a 38-year-old man with a 4-hour history of accidental removal of a jejunostomy balloon-tube replacement (PEG-18-BRT-S, Cook Medical Inc., Bloomington, USA). The patient had undergone a direct percutaneous endoscopic jejunostomy (DPEJ) ten months ago, before chemoradiotherapy treatment for an esophageal squamous-cell carcinoma (uT3N2cM0). His past medical condition included alcoholic liver disease and distal gastrectomy from a life-threatening duodenal bleeding ulcer. PMID- 27701885 TI - Pseudomelanosis duodeni: is there a common denominator? AB - A 76-year-old female patient with a past medical history of diabetes mellitus, stage 3 chronic renal failure and iron deficiency anemia was referred for esophagogastroduodenoscopy (EGD) for evaluation of solid food dysphagia. She had been on oral therapy with ferrous sulfate for several years. Besides a Schatzki's ring the EGD revealed a duodenal mucosa with black-speckled pigmentation. Biopsies were performed and disclosed the deposition of brown (hemosiderin) pigment within macrophages in the lamina propria of normal villi. This endoscopic appearance is called pseudomelanosis duodeni (PD). PMID- 27701886 TI - Nodular colitis: endoscopic image an unusual finding. AB - An 82-year-old male with a history of high blood pressure, COPD, chronic myeloid leukemia, and stage-4 chronic renal failure. Admitted to hospital for lower-limb cellulitis and severe COPD exacerbation, he received antibiotic therapy and bronchodilators. During his hospital stay he developed severe anemia and had an hematochezia event with no diarrhea. A complete colonoscopy found small (4-7 mm) nacreous elevated lesions, circumferential in shape, in the cecum and ascending colon with some bleeding stigmata and submucosal bleeding suggestive of infectious colitis; stool culture was negative and Clostridium difficile toxins were positive. The condition was histologically confirmed. PMID- 27701887 TI - A typical but seldom recognized foreign body in the esophagus of a laryngectomized patient. AB - A 57-year-old man with a past medical history of total laryngectomy for squamous cell carcinoma of the larynx was admitted to our institution 5 months after the procedure, for surgical resection of a local recurrence of the tumor. In the postoperative period, endoscopically guided placement of a nasogastric tube was scheduled, after previous failed attempts. Upper gastrointestinal endoscopy revealed an anastomotic dehiscence, 13 cm distal to the incisors, and a foreign body penetrating through the esophageal wall, 20cm distal to the incisors. We were unable to identify the foreign body with certainty but, after consulting with the assistant otorhinolaryngologist, we realized that it was a voice prosthesis. PMID- 27701888 TI - Acute abdomen from duodenal diverticulitis. A case report. AB - Duodenal diverticula are a rare, usually asymptomatic clinical condition. When a complication arises clinical suspicion is key for the diagnosis. On occasion these patients receive a delayed diagnosis and undergo inadequate medical therapy. We report the case of a patient with evidence of duodenal diverticulitis in association with gallbladder inflammation by contiguity, as well as his diagnosis and management. PMID- 27701889 TI - Fatal Campylobacter jejuni ileocolitis. AB - Campylobacter infection usually starts in the jejunum and ileum and progresses distally. The case fatality rate is low and most occur in elderly or patients with comorbidity as in this case. Antibiotics should be used in severe cases or patients at risk. The choices are macrolides and fluoroquinolones. However, in some countries quinolone resistance is increasing, as in Spain. We shouldn't forget this fact for the proper treatment approach and specifically in refractory cases. PMID- 27701890 TI - Contribution of military psychology in supporting those in rural and remote work environments. AB - CONTEXT: This article explores the relevance of the body of military psychology knowledge to the management and support of those living and working in rural/remote industries and locations, particularly within Australia. ISSUES: For those who live and work in rural/remote settings, there are social, occupational, health and environmental challenges. Some of these are shared with families and individuals who are associated with military life. The published literature on the shared attributes between military and rural/remote work environments rarely makes a direct link. However, looking at both areas suggests opportunities for the application of psychological knowledge in the well-developed field of military psychology to the rural/remote setting. This article focuses on application of psychological knowledge in the areas of occupational performance, fatigue, mental health, family care and in the training of psychologists to work in rural/remote areas. LESSONS LEARNED: The cross-pollination of knowledge between those working with military personnel and family and those working in rural/remote settings should allow practitioners greater opportunities to improve health and wellbeing outcomes in these communities. PMID- 27701891 TI - Recent advances in targeting the fatty acid biosynthetic pathway using fatty acid synthase inhibitors. AB - INTRODUCTION: Elevated lipogenesis has been associated with a variety of diseases including obesity, cancer and nonalcoholic fatty liver disease (NAFLD). Fatty acid synthase (FASN) plays a pivotal role in de novo lipogenesis, making this multi-catalytic protein an attractive target for therapeutic intervention. Recently, the first FASN inhibitor successfully advanced through the drug development process and entered clinical evaluation in oncology. Areas covered: This review discusses the biological roles of FASN in three prominent disease areas: cancer, obesity-related disorders and NAFLD. Recent advances in drug discovery strategies and design of newer FASN inhibitors are also highlighted. Expert opinion: Despite the abundance of evidence linking the lipogenic pathway to cancer, progression of FASN-targeted molecules has been rather slow and challenging and no compounds have moved past the preclinical phase. The landscape has recently changed with the recent advancement of the first FASN inhibitor into clinical evaluation for solid tumors. Needless to say, the successful translation into the clinical setting will open opportunities for expanding the therapeutic utility of FASN inhibitors not just in oncology but in other diseases associated with elevated lipogenesis such as obesity, type 2 diabetes, and NAFLD. PMID- 27701892 TI - Intelligent polymeric micelles: development and application as drug delivery for docetaxel. AB - Recent years, docetaxel (DTX)-loaded intelligent polymeric micelles have been regarded as a promising vehicle for DTX for the reason that compared with conventional DTX-loaded micelles, DTX-loaded intelligent micelles not only preserve the basic functions of micelles such as DTX solubilization, enhanced accumulation in tumor tissue, and improved bioavailability and biocompatibility of DTX, but also possess other new properties, for instance, tumor-specific DTX delivery and series of responses to endogenous or exogenous stimulations. In this paper, basic theories and action mechanism of intelligent polymeric micelles are discussed in detail, especially the related theories of DTX-loaded stimuli responsive micelles. The relevant examples of stimuli-responsive DTX-loaded micelles are also provided in this paper to sufficiently illustrate the advantages of relevant technology for the clinical application of anticancer drug, especially for the medical application of DTX. PMID- 27701893 TI - Recent trends in the transdermal delivery of therapeutic agents used for the management of neurodegenerative diseases. AB - With the increasing proportion of the global geriatric population, it becomes obvious that neurodegenerative diseases will become more widespread. From an epidemiological standpoint, it is necessary to develop new therapeutic agents for the management of Alzheimer's disease, Parkinson's disease, multiple sclerosis and other neurodegenerative disorders. An important approach in this regard involves the use of the transdermal route. With transdermal drug delivery systems (TDDS), it is possible to modulate the pharmacokinetic profiles of these medications and improve patient compliance. Transdermal drug delivery has also been shown to be useful for drugs with short half-life and low or unpredictable bioavailability. In this review, several transdermal drug delivery enhancement technologies are being discussed in relation to the delivery of medications used for the management of neurodegenerative disorders. PMID- 27701894 TI - Whole blood samples for adrenocorticotrophic hormone measurement can be stored at room temperature for 4 hours. AB - INTRODUCTION: The aim of this study was to investigate and compare the stability of adrenocorticotrophic hormone (ACTH) in whole blood stored on ice and at room temperature for up to 48 hours. This study differs from previous studies by a larger data material. MATERIALS AND METHODS: EDTA-blood samples from 30 patients were collected, aliquoted and stored on ice or at room temperature for 0, 2, 4, 24, or 48 h before centrifugation, and the plasma was stored frozen until analysis. All samples were analyzed using an automated electrochemiluminescence immunoassay on cobas 6000 e601. The change in ACTH concentration was illustrated as ACTH recovery compared to standard conditions defined as samples stored immediately on ice, centrifuged and plasma frozen within 1 h. A change in ACTH concentration of more than 10% was considered to be of clinical relevance. RESULTS: The results showed no clinically relevant change in ACTH recovery for up to 4 h compared to standard conditions. For samples stored at room temperature for 4 h, a significant (p < .0001) relative mean change in ACTH concentrations of -4.3% was observed. CONCLUSION: The comparison between samples stored at room temperature for up to 4 h and standard conditions showed that ACTH samples do not require cooling until centrifugation, if a mean difference in ACTH concentration of -4.3%, between the individual results, can be accepted. PMID- 27701895 TI - Speech-language pathology research in the Philippines in retrospect: Perspectives from a developing country. AB - PURPOSE: There is a need for speech-language pathology (SLP) research in the Philippines, in order to fill in knowledge gaps relevant to the local context. Information about the local SLP research status remains inadequate. This study describes local SLP research done over the almost past four decades. METHOD: Using a descriptive retrospective design, a search was made for all empirical research articles completed by Filipino SLPs from 1978 to 2015. RESULT: A total of 250 research articles were identified and described along several parameters. A predominant number were authored by the SLPs in the academe (97.20%). There was a focus on language (27.60%) and the nature of communication/swallowing disorders (20.80%). More than half utilised quantitative exploratory research designs (69.20%). Several used survey forms to generate data (38.41%). Nearly all were unpublished (93.60%) and were unfunded (94.80%). CONCLUSION: The current study revealed a dearth of research studies, limited diversity of research articles, limited research dissemination and funding concerns. It is suggested that the results of the current study can serve as a reference point to restructure research systems in the Philippines and in other developing countries, and offer data that can be used to develop a research agenda for the profession. PMID- 27701896 TI - Intraabdominal microdialysis - methodological challenges. AB - Microdialysis is used for in vivo sampling of extracellular molecules. The technique provides a continuous and dynamic view of concentrations of both endogenous released and exogenous administered substances. Microdialysis carries a low risk of complications and has proven to be a safe procedure in humans. The technique has been applied in several clinical areas, including gastrointestinal surgery. Microdialysis may be used for studies of tissue metabolism, and the technique is also a promising tool for pharmacological studies of drug penetration into abdominal organ tissue and the peritoneal cavity. The clinical significance of intraabdominal microdialysis in postoperative monitoring of surgical patients has yet to be proven. In this review, we introduce the microdialysis technique, and we present an overview of theoretical and practical considerations that should be taken into account when using microdialysis in intraabdominal clinical research. PMID- 27701897 TI - Engineering biosynthesis of high-value compounds in photosynthetic organisms. AB - The photosynthetic, autotrophic lifestyle of plants and algae position them as ideal platform organisms for sustainable production of biomolecules. However, their use in industrial biotechnology is limited in comparison to heterotrophic organisms, such as bacteria and yeast. This usage gap is in part due to the challenges in generating genetically modified plants and algae and in part due to the difficulty in the development of synthetic biology tools for manipulating gene expression in these systems. Plant and algal metabolism, pre-installed with multiple biosynthetic modules for precursor compounds, bypasses the requirement to install these pathways in conventional production organisms, and creates new opportunities for the industrial production of complex molecules. This review provides a broad overview of the successes, challenges and future prospects for genetic engineering in plants and algae for enhanced or de novo production of biomolecules. The toolbox of technologies and strategies that have been used to engineer metabolism are discussed, and the potential use of engineered plants for industrial manufacturing of large quantities of high-value compounds is explored. This review also discusses the routes that have been taken to modify the profiles of primary metabolites for increasing the nutritional quality of foods as well as the production of specialized metabolites, cosmetics, pharmaceuticals and industrial chemicals. As the universe of high-value biosynthetic pathways continues to expand, and the tools to engineer these pathways continue to develop, it is likely plants and algae will become increasingly valuable for the biomanufacturing of high-value compounds. PMID- 27701898 TI - Differential regulation of oxidative stress and cytokine production by endothelin ETA and ETB receptors in superoxide anion-induced inflammation and pain in mice. AB - The present study investigated whether endothelin-1 acts via ETA or ETB receptors to mediate superoxide anion-induced pain and inflammation. Mice were treated with clazosentan (ETA receptor antagonist) or BQ-788 (ETB receptor antagonist) prior to stimulation with the superoxide anion donor, KO2. Intraplantar treatment with 30 nmol of clazosentan or BQ-788 reduced mechanical hyperalgesia (47% and 42%), thermal hyperalgesia (68% and 76%), oedema (50% and 30%); myeloperoxidase activity (64% and 32%), and overt-pain like behaviours, such as paw flinching (42% and 42%) and paw licking (38% and 62%), respectively. Similarly, intraperitoneal treatment with 30 nmol of clazosentan or BQ-788 reduced leukocyte recruitment to the peritoneal cavity (58% and 32%) and abdominal writhing (81% and 77%), respectively. Additionally, intraplantar treatment with clazosentan or BQ-788 decreased spinal (45% and 41%) and peripheral (47% and 47%) superoxide anion production as well as spinal (47% and 47%) and peripheral (33% and 54%) lipid peroxidation, respectively. Intraplantar treatment with clazosentan, but not BQ-788, reduced spinal (71%) and peripheral (51%) interleukin-1 beta as well as spinal (59%) and peripheral (50%) tumor necrosis factor-alpha production. Therefore, the present study unveils the differential mechanisms by which ET-1, acting on ETA or ETB receptors, regulates superoxide anion-induced inflammation and pain. PMID- 27701899 TI - The effect of seasons on Brazilian red propolis and its botanical source: chemical composition and antibacterial activity. AB - The aim of this study was to evaluate the effect of seasons on the chemical composition and antibacterial activity of Brazilian red propolis (BRP) and its plant source. BRP was collected from Maceio, Alagoas state, north-east of Brazil, during one year. Chemical composition was determined by physicochemical analyses and HPLC while antimicrobial activity was assessed against Streptococcus mutans, Streptococcus sobrinus, Staphylococcus aureus and Actinomyces naeslundii by determining the minimal inhibitory and bactericidal concentrations (MIC and MBC, respectively). The comparative chemical profiles varied quantitatively according to the collection period. Formononetin was the most abundant compound in both propolis and resin, while isoliquiritigenin, (3S)-neovestitol, (3S)-vestitol are suggested to be responsible for antimicrobial activity of Brazilian red propolis. MIC varied from 15.6 to 125 MUg/mL, whereas MBC varied from 31.2 to 500 MUg/mL. Therefore, season in which propolis and its botanical source are collected indeed influences their chemical compositions, resulting in variations in their antibacterial activity. PMID- 27701900 TI - Impaired Upregulation of the Costimulatory Molecules, CD27 and CD28, on CD4+ T Cells from HIV Patients Receiving ART Is Associated with Poor Proliferative Responses. AB - HIV patients beginning antiretroviral therapy (ART) with advanced immunodeficiency often retain low CD4+ T cell counts despite virological control. We examined proliferative responses and upregulation of costimulatory molecules, following anti-CD3 stimulation, in HIV patients with persistent CD4+ T cell deficiency on ART. Aviremic HIV patients with nadir CD4+ T cell counts <100 cells/MUL and who had received ART for a median time of 7 (range 1-11) years were categorized into those achieving low (<350 cells/MUL; n = 13) or normal (>500 cells/MUL; n = 20) CD4+ T cell counts. Ten healthy controls were also recruited. CD4+ T cell proliferation (Ki67) and upregulation of costimulatory molecules (CD27 and CD28) after anti-CD3 stimulation were assessed by flow cytometry. Results were related to proportions of CD4+ T cells expressing markers of T cell senescence (CD57), activation (HLA-DR), and apoptotic potential (Fas). Expression of CD27 and/or CD28 on uncultured CD4+ T cells was similar in patients with normal CD4+ T cell counts and healthy controls, but lower in patients with low CD4+ T cell counts. Proportions of CD4+ T cells expressing CD27 and/or CD28 correlated inversely with CD4+ T cell expression of CD57, HLA-DR, and Fas. After anti-CD3 stimulation, induction of CD27hiCD28hi expression was independent of CD4+ T cell counts, but lower in HIV patients than in healthy controls. Induction of CD27hiCD28hi expression correlated with induction of Ki67 expression in total, naive, and CD31+ naive CD4+ T cells from patients. In HIV patients responding to ART, impaired induction of CD27 and CD28 on CD4+ T cells after stimulation with anti-CD3 is associated with poor proliferative responses as well as greater CD4+ T cell activation and immunosenescence. PMID- 27701901 TI - Increased cognitive problem reporting after information about chemotherapy induced cognitive decline: The moderating role of stigma consciousness. AB - OBJECTIVE: Information about treatment side effects can increase their occurrence; breast cancer (BC) patients showed increased cognitive problem reporting (CPR) and decreased memory performance after information about cognitive side effects. The current study extends previous research on adverse information effects (AIE) by investigating (a) risk factors, (b) underlying mechanisms and (c) an intervention to reduce AIE. DESIGN: In an online experiment, 175 female BC patients were randomly assigned to one of three conditions. In the two experimental groups, patients were informed about the possible occurrence of cognitive problems after chemotherapy with (intervention group) or without (experimental group) reassuring information that 'there are still patients who score well on memory tests'. In the control group, no reference to chemotherapy-related cognitive problems was made. MAIN OUTCOME MEASURES: Main dependent measure was CPR. Four moderating and five mediating processes were examined. RESULTS: CPR increased with higher levels of stigma consciousness in the two experimental groups, but not in the no-information control group. CONCLUSION: Merely informing patients about cognitive side effects may increase their occurrence, especially among individuals vulnerable to patient stereotypes. Adding reassuring information is not sufficient to reduce AIE. PMID- 27701903 TI - Responses made by late talkers and typically developing toddlers during speech assessments. AB - PURPOSE: Assessing toddlers' speech is challenging. We explored responses made by late talkers and their typically developing peers in structured speech sampling contexts and determined if late talker subgroups could be identified. METHOD: Twenty-six late talkers and 26 age-matched typically developing toddlers participated in an expressive phonology assessment and an elicited non-word imitation test. We quantified the breadth of toddler responses used in a subset of monosyllabic stimuli from the toddler phonology assessment and in the non-word imitation test. Correlational and cluster analyses were conducted. RESULT: There were six response types: no response, protoword response, different verbal response, correct phoneme, common and uncommon phonological errors. Toddlers' use of most of the response types correlated across the two sampling contexts. Use of the response types also correlated with several direct and parent-report assessments. There were significant group differences in the use of several response types in both sampling contexts. Five late talker subgroups were identified that presented with differing profiles of responses. CONCLUSION: Toddlers respond in a variety of ways during structured speech sampling contexts. Responses made by late talkers offer insights about the nature of late talking and their heterogeneity. Implications for research and clinical management of late talkers are discussed. PMID- 27701902 TI - Motivational interviewing or reminders for glaucoma medication adherence: Results of a multi-site randomised controlled trial. AB - OBJECTIVE: Nonadherence reduces glaucoma treatment efficacy. Motivational interviewing (MI) is a well-studied adherence intervention, but has not been tested in glaucoma. Reminder interventions also may improve adherence. DESIGN: 201 patients with glaucoma or ocular hypertension were urn-randomised to receive MI delivered by an ophthalmic technician (OT), usual care or a minimal behavioural intervention (reminder calls). MAIN OUTCOME MEASURES: Outcomes included electronic monitoring with Medication Event Monitoring System (MEMS) bottles, two self-report adherence measures, patient satisfaction and clinical outcomes. Multilevel modelling was used to test differences in MEMS results by group over time; ANCOVA was used to compare groups on other measures. RESULTS: Reminder calls increased adherence compared to usual care based on MEMS, p = .005, and self-report, p = .04. MI had a nonsignificant effect but produced higher satisfaction than reminder calls, p = .007. Treatment fidelity was high on most measures, with observable differences in behaviour between groups. All groups had high baseline adherence that limited opportunities for change. CONCLUSION: Reminder calls, but not MI, led to better adherence than usual care. Although a large literature supports MI, reminder calls might be a cost-effective intervention for patients with high baseline adherence. Replication is needed with less adherent participants. PMID- 27701905 TI - Lentivirus-mediated angiopoietin-2 gene silencing decreases TNF-alpha induced apoptosis of alveolar epithelium cells. AB - OBJECTIVE: To investigate the role of angiopoietin-2 (Ang-2) in tumor necrosis factor-alpha (TNF-alpha) induced apoptosis of alveolar epithelium cells (AECs). METHODS: TNF-alpha was used to induce human alveolar epithelial HPAEpiC cells, and Ang-2 siRNA vector was transfected to the HPAEpiC cells. RT-PCR and Western blot were used. TUNEL staining was applied to observe apoptosis, and annexin V FITC-PI staining was used to calculate apoptosis rate. RESULTS: mRNA and protein expressions of Ang-2, activated Bax, and cleaved caspase-3 in HPAEpiC cells were up-regulated, but the expression level of Bcl-2 decreased (P < 0.05). After transfection of Ang-2 siRNA, mRNA and protein expressions of Ang-2, activated Bax, and cleaved caspase-3 in HPAEpiC cells were down-regulated, but the expression level of Bcl-2 increased (P < 0.05). The number of apoptotic cells increased after TNF-alpha treatment; however, the number decreased after Ang-2 siRNA transfection. Annexin V-FITC-PI staining verified that the total number of apoptotic cells was elevated with TNF-alpha treatment, but declined after transfection of Ang-2 siRNA. CONCLUSIONS: The expression level of Ang-2 increased during TNF-alpha-induced apoptosis. Inhibiting Ang-2 expression may suppress the early stages of cell apoptosis and the degree of TNF-alpha-induced apoptosis. PMID- 27701904 TI - Impedance aggregometric analysis of platelet function of apheresis platelet concentrates as a function of storage time. AB - Multiple electrode (impedance) aggregometry (MEA) allows reliable monitoring of platelet function in whole blood. The aims of the present study were to implement MEA for analyzing aggregation in platelet concentrates and to correlate results with storage time and blood gas analysis (BGA). We investigated the influence of platelet counts, calcium concentrations and agonists on platelet aggregation. Samples of apheresis concentrates up to an age of 12 days were investigated by MEA and BGA. For ASPI- and TRAPtest MEA was reproducible for a platelet count of 400 per 10-9 L and a calcium concentration of 5 mmol L-1. Platelets at the age of 2-4 days yielded steady aggregation. Platelet concentrates exceeding the storage time for transfusion showed steady aggregation up to 10 days, but a significant decline on day 12. Weak correlation was found regarding pCO2 and MEA as well as regarding glucose concentration and MEA. Our results indicate that MEA is applicable for evaluation of aggregation in stored apheresis concentrates. Prolonged storage seems not to be prejudicial regarding platelet aggregation. Platelet concentrates showed acceptable BGA throughout storage time. Further studies are required to evaluate the application of MEA for quality controls in platelet concentrates. PMID- 27701906 TI - ESCRTs and associated proteins in lysosomal fusion with endosomes and autophagosomes. AB - Endolysosomal and autophagosomal degradation pathways are highly connected at various levels, sharing multiple molecular effectors that modulate them individually or simultaneously. These two lysosomal degradative pathways are primarily involved in the disposal of cargo internalized from the cell surface or long-lived proteins or aggregates and aged organelles present in the cytosol. Both of these pathways involve a number of carefully regulated vesicular fusion events that are dependent on ESCRT proteins. The ESCRT proteins especially ESCRT I and III participate in the regulation of fusion events between autophagosome/amphisome and lysosome. Along with these, a number of functionally diverse ESCRT associated and regulatory proteins such as, endosomal PtdIns (3) P 5-kinase Fab1, ALIX, mahogunin ring finger 1, atrogin 1, syntaxin 17, ATG12-ATG3 complex, and protein kinase CK2alpha are involved in fusion events in either or both the lysosomal degradative pathways. PMID- 27701908 TI - Sub-optimal adherence to combination anti-retroviral therapy and its associated factors according to self-report, clinician-recorded and pharmacy-refill assessment methods among HIV-infected adults in Addis Ababa. AB - Adherence to combination antiretroviral therapy (cART) is generally high in most resource-limited settings. However, sub-optimal adherence occurs in a sizable proportion of patients, and is independently predictive of detectable viremia. We investigated sub-optimal adherence according to self-report, clinician-recorded, and pharmacy-refill assessment methods, and their associated factors among HIV infected adults receiving cART in Addis Ababa, Ethiopia. Eight-hundred seventy patients who initiated cART between May 2009 and April 2012 were randomly selected, and 664 patients who were alive, had remained in clinical care and were receiving cART for at least six-months were included. Sub-optimal adherence was defined as patients' response of less than "all-of the time" to the self-report adherence question, or any clinician-recorded poor adherence during the six most recent clinic visits, or a pharmacy-refill of <95% medication possession ratio (MPR). Logistic regression models were fitted to identify factors associated with sub-optimal adherence. The average adherence level to cART, expressed as MPR, was nearly 97%. However, sub-optimal adherence occurred in 12%, 4%, and 27% of patients according to self-report, clinician-recorded, and pharmacy-refill measures, respectively. More satisfaction with social support was significantly associated with less sub-optimal adherence according to self-report and clinician record. Younger age, lower educational level, and lower CD4 cell count at cART initiation were significantly associated with sub-optimal refill-based adherence. Findings from our large multi-center study suggest that sub-optimal adherence was present in up to a quarter of the patients, despite a high degree of average adherence to cART. Interventions aimed at preventing sub-optimal adherence should focus on improving social support, on younger patients, on patients with lower educational level, and on those who started cART at a lower CD4 cell count. PMID- 27701907 TI - Speech and nonspeech: What are we talking about? AB - Understanding of the behavioural, cognitive and neural underpinnings of speech production is of interest theoretically, and is important for understanding disorders of speech production and how to assess and treat such disorders in the clinic. This paper addresses two claims about the neuromotor control of speech production: (1) speech is subserved by a distinct, specialised motor control system and (2) speech is holistic and cannot be decomposed into smaller primitives. Both claims have gained traction in recent literature, and are central to a task-dependent model of speech motor control. The purpose of this paper is to stimulate thinking about speech production, its disorders and the clinical implications of these claims. The paper poses several conceptual and empirical challenges for these claims - including the critical importance of defining speech. The emerging conclusion is that a task-dependent model is called into question as its two central claims are founded on ill-defined and inconsistently applied concepts. The paper concludes with discussion of methodological and clinical implications, including the potential utility of diadochokinetic (DDK) tasks in assessment of motor speech disorders and the contraindication of nonspeech oral motor exercises to improve speech function.

AB - We conducted a retrospective registry-based study involving 198 patients with acute promyelocytic leukemia (APL) who underwent autologous hematopoietic cell transplantation (HCT) during second complete remission (CR2) from 1995 to 2012. Arsenic trioxide (ATO) became commercially available in Japan in December 2004, and a substantial increase in the annual numbers of transplantations has occurred since 2005. Patients transplanted after 2006 had significantly better relapse free and overall survival than those transplanted before 2004 (p = .028 and p = .027, respectively). There was a significant difference in cumulative incidence of relapse in favor of those transplanted after 2006 (p = .008), whereas non relapse mortality did not differ between the two groups (p = .683). Our findings suggest that the introduction of ATO may have reduced post-transplantation relapse without increasing non-relapse mortality, resulting in significant improvements in overall outcomes for relapsed APL patients undergoing autologous HCT during CR2. PMID- 27701910 TI - Impact of ABC single nucleotide polymorphisms upon the efficacy and toxicity of induction chemotherapy in acute myeloid leukemia. AB - Anthracycline uptake could be affected by efflux pumps of the ABC family. The influence of 7 SNPs of ABC genes was evaluated in 225 adult de novo acute myeloid leukemia (AML) patients. After multivariate logistic regression there were no significant differences in complete remission, though induction death was associated to ABCB1 triple variant haplotype (p = .020). The ABCB1 triple variant haplotype was related to higher nephrotoxicity (p = .016), as well as this haplotype and the variant allele of ABCB1 rs1128503, rs2032582 to hepatotoxicity (p = .001; p = .049; p < .001). Furthermore, the variant allele of ABCC1 rs4148350 was related to severe hepatotoxicity (p = .044), and the variant allele of ABCG2 rs2231142 was associated to greater cardiac (p = .004) and lung toxicities (p = .038). Delayed time to neutropenia recovery was observed with ABCB1 rs2032582 variant (p = .047). This study shows the impact of ABC polymorphisms in AML chemotherapy safety. Further prospective studies with larger population are needed to validate these associations.

AB - Although fertility educational initiatives have increased in developed countries to prevent infertility and to broaden fertility choices, the relationship between knowledge and behaviour is still poorly understood. In order to investigate the association between fertility knowledge and timing of childbearing, we investigated male and female participants between 35 and 44 years of age who had children (n = 640) from an online survey conducted in Japan in 2013. The age at which participants actually gave birth to or fathered their first child was compared between those who were aware for at least a decade of age-related decline in female fertility (hereinafter, those with past fertility knowledge) and those without. Age at first birth was significantly younger and more narrowly distributed among women with past fertility knowledge than among those without: 28.2 +/- 3.4 vs. 29.8 +/- 4.6 (mean +/- SD). A multivariate linear regression analysis showed that women with past fertility knowledge gave birth to their first child 2.34 [95% confidence interval (CI): 1.09-3.59] years earlier compared to those without such knowledge. No significant relation existed among men. Being informed in young adulthood about the facts of fertility might be related to starting a family at an earlier age, although further longitudinal evaluation will be necessary. PMID- 27701915 TI - Postpartum haemorrhage: prevention and treatment. AB - INTRODUCTION: Postpartum hemorrhage (PPH) is one of the leading causes of maternal death and severe maternal morbidity worldwide and strategies to prevent and treat PPH vary among international authorities. Areas covered: This review seeks to provide a global overview of PPH (incidence, causes, risk factors), prevention (active management of the third stage of labor and prohemostatic agents), treatment (first, second and third-line measures to control PPH), by also underlining recommendations elaborated by international authorities and using algorithms. Expert commentary: When available, oxytocin is considered the drug of first choice for both prevention and treatment of PPH, while peripartum hysterectomy remains the ultimate life-saving procedure if pharmacological and resuscitation measures fail. Nevertheless, the level of evidence for preventing and treating PPH is globally low. The emergency nature of PPH makes randomized controlled trials (RCT) logistically difficult. Population-based observational studies should be encouraged as they can usefully strengthen the evidence base, particularly for components of PPH treatment that are difficult or impossible to assess through RCT.

AB - Resonance-based contact-impedance measurement refers to the application of resonance sensors based on the measurement of the changes in the resonance curve of an ultrasonic resonator in contact with a surface. The advantage of the resonance sensor is that it is very sensitive to small changes in the contact impedance. A sensitive micro tactile sensor (MTS) was developed, which measured the elasticity of soft living tissues at the single-cell level. In the present paper, we studied the method of improving the touch and stiffness sensitivity of the MTS. First, the dependence of touch sensitivity in relation to the resonator length was studied by calculating the sensitivity coefficient at each length ranging from 9 to 40 mm. The highest touch sensitivity was obtained with a 30-mm long glass needle driven at a resonance frequency of 100 kHz. Next, the numerical calculation of contact impedance showed that the highest stiffness sensitivity was achieved when the driving frequency was 100 kHz and the contact-tip diameter of the MTS was 10 MUm. The theoretical model was then confirmed experimentally using a phase-locked-loop-based digital feedback oscillation circuit. It was found that the developed MTS, whose resonant frequency was 97.030 kHz, performed with the highest sensitivity of 53.2 * 106 Hz/N at the driving frequency of 97.986 kHz, i.e. the highest sensitivity was achieved at 956 Hz above the resonant frequency. PMID- 27701918 TI - Radiofrequency ablation combined with percutaneous ethanol injection for hepatocellular carcinoma: a systematic review and meta-analysis. AB - BACKGROUND: Radiofrequency ablation (RFA) and percutaneous ethanol injection (PEI) are important treatments for patients with hepatocellular carcinoma (HCC) who are not eligible for resection and liver transplantation. Therefore, it is important to establish comparisons between RFA, PEI and the two therapies in combination. AIMS: To evaluate the clinical efficacy and safety of combined RFA PEI versus monotherapy with either RFA or PEI for HCC to provide references for clinical practice and further research. METHODS: We searched all eligible studies published before September 2015 in the Cochrane Library, PubMed, Embase, Web of Science and Chinese databases, such as CBM, CNKI, VIP and WanFang and also retrieved papers from other sources. All relevant controlled trials were collected. Meta-analyses were performed using RevMan version 5.3 software (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark). RESULTS: Thirteen trials with 1621 patients were identified. Compared with PEI, RFA was associated with significant improvement in overall survival (OS) rate at 1, 2, 3 and 4 years, cancer-free survival (CFS) rate at 1, 2 and 3 years and complete tumour necrosis. RFA was associated with a significant reduction in the local recurrence rate at 1, 2 and 3 years. However, RFA was also associated with a higher total risk of complications. Compared with RFA alone, combined RFA-PEI was associated with a significant improvement in the OS rate at 1.5, 2 and 3 years and a significant reduction in the local recurrence rate. However, combined RFA-PEI was also associated with a higher risk of fever. CONCLUSION: The combination of RFA and PEI appears to be the optimal treatment strategy when considering combined RFA-PEI or either RFA or PEI alone. Combined RFA-PEI significantly improves OS and reduces the risk of local recurrence without increasing major complications. Further large-scale studies are needed to assess economic outcomes and quality of life. PMID- 27701919 TI - Caring for juveniles with mental disorders in adult corrections facilities. AB - Although juveniles have developmental, educational, healthcare, and rehabilitation needs that differ from adults, thousands of them have been confined in adult corrections facilities in the past 30 years. This manuscript will review how and why juveniles end up in adult corrections facilities, who they are, their rehabilitative needs, and how they differ from adults in corrections facilities and youths in the juvenile justice system. The importance of providing developmentally-informed mental health services to youths in adult corrections facilities is examined, along with barriers to traditional adolescent psychiatric practice. Recommendations for future directions in adolescent psychiatric care are presented. PMID- 27701920 TI - Status and advancement of microwave ablation in China. AB - Tumour ablation is defined as the direct application of chemical or thermal therapy to eradicate or substantially destroy a tumour. Currently, minimally invasive ablation techniques are available for the local destruction of focal tumours in multiple organ sites. Microwave ablation (MWA) is premised on the biological response of solid tumours to tissue hyperthermia, and it is a relatively low-risk procedure. Due to several advantages of MWA, including higher thermal efficiency, higher capability for coagulating blood vessels, faster ablation time and the simultaneous application of multiple antennae, MWA could be a promising minimally invasive ablation technique for the treatment of solid tumours. Therefore, the use of MWA has developed rapidly in China during the last decade. Many successful studies have been performed, and widespread use has been achieved for multiple types of tumours in China, especially for liver cancer. This review will describe the state-of-the-art of MWA in China, including the development of MWA equipment and its application in the treatment of multiple types of tumours. PMID- 27701921 TI - Cost-effectiveness of intravitreal aflibercept versus other treatments for wet age-related macular degeneration in Japan. AB - OBJECTIVE: This analysis estimated the cost-effectiveness of intravitreal aflibercept injection(s) (IAI) for wet age-related macular degeneration (wAMD) compared with other treatments in Japan. METHODS: This was a cost-utility analysis based on published data. A state-transition cohort model was constructed with six health states based on best-corrected visual acuity in the better-seeing eye. The cycle time was 4 weeks, and the time horizon was 12 years. The model compared IAI 2 mg every 8 weeks (2q8) for 2 years after three initial monthly injections, ranibizumab as needed, ranibizumab 0.5 mg every 4 weeks (0.5q4), pegaptanib sodium 0.3 mg every 6 weeks, verteporfin photodynamic therapy (PDT), and best supportive care, assumed to include medical management and monitoring, but no active therapy. Costs (expressed as Japanese yen [JPY]) and quality adjusted life years (QALYs) gained were estimated for each treatment and discounted at 2.0%. Input data were obtained from clinical studies, the Japanese drug tariff and social insurance reimbursement schedule, and expert opinion. The analysis was conducted from the societal perspective, including medical costs as well as costs of blindness. RESULTS: IAI 2q8 was dominant (i.e. more effective in terms of QALYs and less costly) to all other comparators (ranibizumab as needed, ranibizumab 0.5q4, pegaptanib sodium, PDT, and best supportive care), as shown by the incremental cost-utility ratio (i.e. cost per QALY gained). LIMITATIONS: The strengths of the analysis include the wide range of comparators evaluated and the use of Japanese-specific utility data. The limitations include the use of one eye, inclusion of published data up to 2 years only, and assumptions on disease course over 5 years. CONCLUSIONS: IAI 2q8 was more effective in terms of QALYs and less costly compared with other treatments for wAMD in Japan. PMID- 27701922 TI - Myeloperoxidase deficiency enhances zymosan phagocytosis associated with up regulation of surface expression of CD11b in mouse neutrophils. AB - Myeloperoxidase (MPO), a major component of neutrophils, catalyzes the production of hypochlorous acid (HOCl) from hydrogen peroxide and chloride anion. Phagocytosis is a critical event induced by neutrophils for host defense and inflammation. Interestingly, we found that MPO-deficient (MPO-/-) neutrophils engulfed larger amounts of zymosan than wild-type neutrophils. Blocking of the CD11b subunit of complement receptor 3 (CR3) as well as inhibition of focal adhesion kinase (FAK) and extracellular signal-regulated kinase (ERK) dramatically reduced zymosan phagocytosis. In contrast, blocking of dectin-1, toll-like receptor 2 (TLR2), or spleen tyrosine kinase (Syk) had no significant effects on phagocytosis. Western blotting analysis showed that inhibition of FAK decreased the phosphorylation of ERK1/2, indicating that ERK1/2 is a downstream regulator of FAK in neutrophils. Importantly, we found that cell surface expression of CD11b and phosphorylation of ERK1/2 was significantly higher in zymosan-stimulated MPO-/- neutrophils than in zymosan-stimulated wild-type neutrophils. Pretreatment with the MPO inhibitor 4-aminobenzoic acid hydrazide dramatically enhanced both zymosan phagocytosis and the surface expression of CD11b in wild-type neutrophils, but not in MPO-/- neutrophils. Collectively, these results strongly suggest that up-regulation of the CD11b/FAK/ERK signaling pathway due to absence of MPO enhances the zymosan phagocytic activity of mouse neutrophils. PMID- 27701923 TI - Benign thyroid nodules treatment using percutaneous laser ablation (PLA) and radiofrequency ablation (RFA). AB - PURPOSE: To evaluate the reduction over time of benign thyroid nodules treated using percutaneous laser ablation (PLA) and radiofrequency ablation (RFA) by the same equipe. MATERIALS AND METHODS: Ninety patients (age 55.6 +/- 14.1 years) underwent ablation for benign thyroid nodule causing compression/aesthetic dissatisfaction from 2011. Fifty-nine (age 55.8 +/- 14.1 years) underwent RFA and 31 (age 55.2 +/- 14.2 years) PLA, ultrasound guided. Technical success, complications, duration of ablation and treatment, energy deployed, volumetric percentage reduction at 1, 6 and 12 months were derived. A regression model for longitudinal measurements was used with random intercept and random slope. Values are expressed as mean +/- standard deviation or N (%). RESULTS: Technical success was always obtained. No major complications occurred. Mean ablation time was 30.1 +/- 13.8 vs. 13.9 +/- 5.9 min (p < .0001) and mean energy deployment was 5422.3 +/- 2484.5 J vs. 34 662.7 +/- 15 812.3 J in PLA vs. RFA group. Mean volume reduced from 20.3 +/- 16.4 ml to 13.17 +/- 10.74 ml (42% +/- 17% reduction) at 1st month, 8.7 +/- 7.4 ml (60% +/- 15% reduction) at 6th month and 7.1 +/- 7.7 ml (70%% +/- 16% reduction) at 12th month, in PLA group, and from 32.7 +/- 19.5 ml to 17.2 +/- 12.9 ml (51%+/-15% reduction) at 1st month, 12.8 +/- 9.6 ml (64 +/- 14% reduction) at 6th month and 9.9 +/- 9.2 ml (74% +/- 14% reduction) at 12th month in RFA group. No difference in time course of the relative volume reduction between the two techniques was found. CONCLUSIONS: RFA and PLA are similarly feasible, safe and effective in treating benign thyroid nodules when performed by the same equipe. RFA is faster than PLA but require significantly higher energy. PMID- 27701924 TI - Targeting factors for change: contraceptive counselling and care of female adolescents. AB - INTRODUCTION: Sexual and reproductive health care should empower and enable all individuals to have a sex life that is as safe and pleasurable as possible. Achievement of this goal for adolescents is often impeded by regional and sociocultural barriers. OBJECTIVES: To review global barriers to provision of effective counselling and care of adolescents seeking advice on contraception and sexual and reproductive health and identify elements of best practice that can be adapted to meet their needs at regional level. METHODS: Experts with clinical experience and a scholarly background in the provision of contraceptive services to adolescents participated in a stepwise process of literature review and discussion according to the agreed objectives. RESULTS: The Global CARE (Contraception: Access, Resources, Education) group identified barriers to the access, availability and acceptance of contraception by adolescents, not only at the political and sociocultural level but also within health care practice. The group collected and summarized successful local strategies and tools suitable for adaptation in other regions. Elements of best practice for providing contraception regardless of setting or regional constraints, including required skills, knowledge, and attitudes, were also proposed. CONCLUSION: Sharing of evidence-based best practice in delivering contraceptive services, improvements in health care provider education, and sharing of experience between countries will hopefully help to overcome the barriers to appropriate and effective counselling and care of adolescents.

PMID- 27701926 TI - Twenty-five years of the international Bled course for teachers of family medicine in Europe: Glancing back and looking forward. AB - The international Bled course for teacher training has played a central role in faculty development in family medicine for the past 25 years. The course was originally designed to promote faculty development for family medicine teachers in the new academic discipline of family medicine in Slovenia in 1990 and to introduce new topics into the family medicine curriculum. In this background paper, we perform a SCOT analysis (strengths, challenges, opportunities, and threats) of the current course, evaluating participant feedback and reviewing past topics and their impact on local and international teaching programmes. We also review the place of the course in the context of other teacher-training programmes in family medicine in Europe. We found that the structure and learning aims of the Bled course have remained stable over 25 years. It provides a safe, well-structured learning environment for the participants even though the course topic is different every year. The course has had a significant impact on curriculum development and teacher training in Slovenia as well as in many other countries in Europe and beyond. Because of the positive impact of the course and the high degree of satisfaction of the participants and course directors, it seems worthwhile to continue this endeavour. New directions for the course will depend on the learning needs of the participants and the evolving medical curricula in the countries they represent. PMID- 27701927 TI - Chlamydia screening and prophylactic treatment in termination of pregnancy clinics in the Netherlands and Great Britain: a qualitative study. AB - BACKGROUND: Women having a termination of pregnancy (TOP) have higher rates of Chlamydia trachomatis (CT) than the general population. In this study, we explored CT treatment and prevention in Dutch TOP clinics in comparison to that provided in Great Britain (GB). METHODS: A qualitative study including 14 semi structured interviews with health care professionals (HCPs) in TOP clinics (the Netherlands: 9, GB: 5). Interviews were recorded, transcribed, and analysed by thematic content analysis. RESULTS: Prophylactic treatment with azithromycin is routinely prescribed after surgical TOP, but not after medical TOP ('abortion pill'). Sexually transmitted infections (STI) tests are offered to clients who are considered at high risk of having STI. Uptake varies according to health insurance coverage of STI testing. Some Dutch clinics are able to provide free testing for women under 25 years of age. Sexual health counselling is often limited to discussing birth control. The major difference between the Netherlands and GB is that GB TOP clinics more often offer free STI testing and prophylaxis to their clients. CONCLUSION: HCPs in Dutch TOP clinics consider STI testing an important part of their service, but financial barriers prevent testing on location. Dutch TOP clinics should offer STI tests to all women, and collaboration with public health services could improve STI testing and counselling for young people. Furthermore, clinics should treat all TOP clients with prophylactic azithromycin. This could prevent CT and other upper genital tract post-abortion infections. PMID- 27701928 TI - Pica as a manifestation of iron deficiency. AB - INTRODUCTION: Pica is the compulsive eating of non-nutritive substances. It is often associated with iron deficiency but its pathophysiology is unknown. Areas covered: We searched the literature using the keywords listed below. Our aim was to describe the phenomenon in its various aspects, to touch briefly on the historical and cultural background, and to examine in more detail the studies that tried to analyze the relative roles of iron deficiency and pica. Expert commentary: Pica is an intriguing symptom known for centuries. Pregnant women and preadolescents are at the highest risk of pica. Iron absorption is reduced in the presence of non-nutritive substances. Iron therapy usually cures the pica behavior. There are different forms of pica, one caused directly by iron deficiency probably due to the lack of iron in some areas of the brain and one more culturally driven and including mostly geophagy. PMID- 27701929 TI - Evaluation of the Cytotoxic Effects of Hyperthermia and 5-Fluorouracil Loaded Magnetic Nanoparticles on Human Colon Cancer Cell Line HT-29. AB - The purpose of this study was to evaluate the combined effects of heat and poly lactic-co-glycolic acid (PLGA) nanoparticles, as 5-fluorouracil carriers with/without iron oxide core, on the viability and proliferation capacity of human colon cancer cell line HT-29 in the spheroid model. HT-29 spheroid cells were treated with different concentrations of 5-FU or 5-FU loaded into both nanoparticles for 74 h. Hyperthermia was then performed at 43 degrees C for 60 min. Finally, the effects of the mentioned treatments on cell viability and proliferation capacity were evaluated using the trypan blue dye exclusion test and colony formation assay, respectively. Our results showed that hyperthermia, in combination with 5-FU or PLGA nanoparticles as 5-FU carriers, significantly enhanced the cytotoxic effects as compared to the control group. Considering that nanoparticles could increase the intracellular concentration of drugs in cancer cells, the extent of cytotoxic effects following treatment with 5-FU loaded into both nanoparticles was significantly higher than that with free 5-FU. In addition, the presence of iron oxide cores in nanoparticles during hyperthermia enhanced the cytotoxic effects of hyperthermia compared with nanoparticles without iron oxide core. Based on this study, hyperthermia in combination with 5 FU-loaded PLGA nanoparticles with iron oxide core drastically reduced the proliferation capacity of HT-29 cells; therefore, it may be considered a new direction in the treatment of colon cancer. PMID- 27701932 TI - Introduction. PMID- 27701930 TI - Prasugrel hydrochloride for the treatment of acute coronary syndrome patients. AB - INTRODUCTION: Dual antiplatelet therapy (DAPT) with aspirin combined with either a thienopyridine (clopidogrel or prasugrel) or acyclopentyl-triazolo-pyrimidine (ticagrelor) plays a vital role in the management of acute coronary syndrome (ACS) especially in those undergoing percutaneous coronary intervention (PCI) but even those being managed medically. Observational studies and some formal studies have shown patients on the standard dual antiplatelet regimen (clopidogrel and aspirin) continue to have further ischemic events and can suffer stent thrombosis. It has been demonstrated that clopidogrel is associated with a delayed onset of action with a considerable inter-individual variation to treatment thus making it difficult to achieve an optimal level of platelet inhibition. Areas covered: This article will review the current evidence that is available regarding the effectiveness and safety of prasugrel in ACS patients undergoing percutaneous coronary intervention (PCI). Expert commentary: Prasugrel is an oral third-generation inhibitor of platelet activation and aggregation. Laboratory studies and early phase clinical trials show prasugrel has a faster onset of action, is more potent and has reduced inter-patient response variability compared to clopidogrel. The published studies so far demonstrated that prasugrel when compared to clopidogrel also shows a higher degree of effectiveness in the prevention of platelet-initiated thrombotic events in patients with ACS undergoing PCI, however these benefits are offset somewhat by an increased bleeding risk. PMID- 27701933 TI - Technical interventions to increase adenoma detection rate in colonoscopy. AB - INTRODUCTION: Adenoma detection rate (ADR) is the most robust colonoscopy quality metric and clinical studies have adopted it as the ideal method to assess the impact of technical interventions. Areas covered: We reviewed papers focusing on the impact of colonoscopy technical issues on ADR, including withdrawal time and technique, second evaluation of the right colon, patient positional changes, gastrointestinal assistant participation during colonoscopy, water-aided technique, optimization of bowel preparation and antispasmodic administration. Expert commentary: Overall, technical interventions are inexpensive, available worldwide and easy to implement. Some of them, such as the adoption of split dose regimen and slow scope withdrawal to allow a careful inspection, have been demonstrated to significantly improve ADR. Emerging data support the use of water exchange colonoscopy. According to published studies, other technical interventions seem to provide only marginal benefit to ADR. Unfortunately, the available evidence has methodological limitations, such as small sample sizes, the inclusion of expert endoscopists only and the evaluation of single technical interventions. Additionally, larger studies are needed to clarify whether these interventions might have a higher benefit on low adenoma detectors and whether the implementation of a bundle of them, instead of a single technical maneuver, might have a greater impact on ADR. PMID- 27701934 TI - Impact of EMPA-REG OUTCOME(r) on the management of type 2 diabetes mellitus: a review for primary care physicians. AB - Cardiovascular (CV) disease is the leading cause of death in patients with type 2 diabetes mellitus (T2DM). Most published trials of glucose-lowering agents have shown no significant CV benefit or increased risk of death or heart failure, with the exception of metformin. Three novel classes of glucose-lowering agents, dipeptidyl peptidase 4 (DPP-4) inhibitors, glucagon-like peptide 1 (GLP-1) receptor agonists, and sodium glucose cotransporter 2 (SGLT2) inhibitors, have been approved by the U.S. Food and Drug Administration for the treatment of T2DM in the United States and have also been available in other parts of the world in the past decade. Of the SGLT2 inhibitors, empagliflozin has demonstrated a CV benefit in the Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients-Removing Excess Glucose (EMPA-REG OUTCOME(r)) while trials with other SGLT2 inhibitors are still ongoing. Empagliflozin has also provided possible renal protective benefit in those with mild-to-moderate renal impairment. The mechanisms behind the benefits seen with empagliflozin are likely multifactorial. Empagliflozin is the reasonable choice for add-on therapy in patients with long-standing T2DM who are at high CV risk as demonstrated in the EMPA-REG OUTCOME(r) study. PMID- 27701935 TI - Surrogate markers of visceral fat and response to anti-depressive treatment in patients with major depressive disorder: a prospective exploratory analysis. AB - BACKGROUND: Body mass index (BMI) and body weight have been shown to be associated to treatment outcome in patients with major depressive disorder, but this relationship is not clear. Visceral fat might be an underlying mechanism explaining this relationship. AIMS: The aim of this study was to prospectively investigate whether visceral fat, as measured by hip-to-waist ratio and waist circumference, affects treatment outcome in patients with major depressive disorder in patients attending a hospital psychiatric care unit in Denmark. METHODS: The study was conducted as an observational prospective study including 33 patients with major depressive disorder. Assessments were made at enrolment and after 8 weeks. Primary variables were hip-to-waist ratio and waist circumference. Outcome were remission or response of depressive symptoms measured with the Hamilton Depression Rating Scale (HAM-D17) interviews and HAM-D6 self rating questionnaires. RESULTS: No differences were found in outcome between groups of patients with high vs low visceral fat in this population. CONCLUSIONS: The lack of association was evident for all surrogate markers of visceral fat, and suggests that visceral fat has no impact on outcomes of depressive symptoms. However, study limitations might have contributed to this lack of association, especially sample size and considerable variations on multiple parameters including treatment received during the 8 weeks of follow-up. PMID- 27701936 TI - Opioid and amphetamine dependence is associated with methicillin-resistant Staphylococcus aureus (MRSA): An epidemiological register study with 73,201 Swedish in- and outpatients 1997-2013. AB - BACKGROUND: While methicillin-resistant Staphylococcus aureus (MRSA) is increasing in prevalence globally, Sweden is still a low-prevalence country enabling studies on the natural MRSA spread in subpopulations unaffected by a surrounding highly infected population. Substance dependence and injection drug use have been risk factors for MRSA carriage and infection in other countries. In this retrospective, longitudinal register study, we investigated MRSA epidemiology 1997-2013 in opioid and amphetamine-dependent individuals, in comparison with alcohol-dependent subjects. METHODS: Data from the national Swedish in- and outpatients registers included 73,201 individuals from 1997, 1999, 2004, 2009 and 2013. We analyzed substance use disorder and demographic predictors for MRSA using generalized estimating equations. RESULTS: The main finding was that both opioid (adjusted odds ratio [AOR] = 2.82; 95% confidence interval [CI] = 2.16, 3.67) and amphetamine dependence (AOR = 2.71; 95% CI = 1.70, 4.16) were significantly associated with MRSA diagnosis compared with alcohol dependence, when adjusting for age, sex and year. CONCLUSIONS: These findings are of value to understand the dynamics of MRSA epidemiology among substance dependent persons with presumably low socioeconomic status and potential injection drug use, and implicate repeated surveillance of MRSA among these patients. PMID- 27701937 TI - Impact of cognitive impairment, depression, disease activity, and disease damage on quality of life in women with systemic lupus erythematosus. AB - OBJECTIVES: To define the relative role of cognitive impairment, depression, disease activity, and disease damage in the decreased health-related quality of life (HRQoL) frequently observed in systemic lupus erythematosus (SLE) patients. METHOD: We studied 101 Chilean female SLE patients and applied the 12-item Medical Outcomes Study (MOS) Short Form Health Survey version 2 (SF-12v2) to assess HRQoL and the Cambridge Neuropsychological Test Automated Battery (CANTAB) to assess cognitive function. Analysis of covariance (ANCOVA) models included demographic and disease-related factors and cognitive function tests of sustained attention, memory, and executive function. RESULTS: All measures of HRQoL were lower in the 101 female SLE patients compared to the women from the Chilean general population. HRQoL was associated with the following factors: (i) depression symptoms, which were detrimental to all components of the physical and mental HRQoL scores; (ii) executive dysfunction (spatial planning), which was associated with lower scores on role limitations due to physical health problems and emotional problems, and general health perceptions; (iii) higher activity and organ damage were deleterious to role physical, bodily pain, and physical summary scores; and (iv) higher damage also impacted physical function. Impairments in sustained attention and memory did not decrease the HRQoL. CONCLUSIONS: Our results highlight the relevance of executive dysfunction to poor physical and mental health components of HRQoL in SLE together with depression, while disease activity and disease damage are associated with lower HRQoL physical components. The need for cognitive function evaluation and rehabilitation in SLE is indicated.

AB - AIM: Sexual dysfunction, common in schizophrenia, may be further exaggerated by antipsychotics, especially those of First Generation (FGAs), and antidepressants, such as Selective Serotonin Reuptake Inhibitors (SSRs). Mirtazapine, an antidepressant characterized by its different action mechanism compared with that of the majority of other antidepressants, may improve SSRI-induced sexual dysfunction in patients with depression. It is unknown, however, whether mirtazapine improves sexual functioning in schizophrenia. METHODS: This study randomly assigned FGA-treated patients with schizophrenia to receive either an add-on mirtazapine (n = 20) or a placebo (n = 19) for 6 weeks. Sexual functioning was prospectively measured using five relevant items from the Udvalg for Kliniske Undersogelser side-effect rating scale (UKU-SERS). RESULTS: Orgasmic function improved with statistical significance in the mirtazapine group (p = .03), with no changes in any other sexual functions in either group. CONCLUSION: Add-on mirtazapine appears to relieve orgasmic dysfunction in FGA-treated patients with schizophrenia. PMID- 27701965 TI - Saksenaea erythrospora, an emerging mucoralean fungus causing severe necrotizing skin and soft tissue infections - a study from a tertiary care hospital in north India. AB - BACKGROUND: Saksenaea erythrospora is an emerging and recently described pathogenic fungus mainly causing invasive cutaneous infections. Globally, very few human cases, caused by S. erythrospora, have been reported. In India, among the genus Saksenaea, S. vasiformis was the only reported pathogenic species, until recently when a case of fungal rhinosinusitis was reported to be caused by S. erythrospora. We observed five human cases of necrotizing skin and soft tissue infections caused by S. erythrospora following traumatic implantation over 1-year study period. METHODS: The study was conducted for a year observing the causative role of Saksenaea species in primary cutaneous necrotizing infections. The clinical entities were diagnosed by both microbiological and histopathological examination of the skin biopsies. The final identification of fungal strains was done by comparing internal transcribed spacer (ITS) and D1-D2 domains of the LSU (larger subunit) of the nuclear ribosomal RNA (rRNA) sequences with those of type strains of the different species of Saksenaea. RESULTS: Out of total 23 cases of necrotizing skin and soft tissue infections, 5 were caused by S. erythrospora. Intramuscular injection into the gluteal region was the predisposing factor in four patients, while upper limb involvement, following medicated adhesive tape application, was seen in one patient. All patients were treated with liposomal amphotericin B (LAMB) along with extensive debridement of necrotic tissues. Four patients responded well however one died. CONCLUSION: Saksenaea erythrospora is an emerging mucoralean fungus isolated in India among patients undergoing inadvertent I/M injections entailing necrotizing fasciitis at the local site.

AB - CONCLUSION: Mandarin-speaking adults can use the Fine Structure Processing (FSP) coding strategy as well as the Continuous Interleaved Sampling (CIS+) coding strategy. No loss in performance was observed after switch-over. Tone identification improves over time with the FSP coding strategy, which is of benefit to tonal-language users. After some time, fine structure was preferred. OBJECTIVE: This study aimed to determine speech perception, tone perception, and the subjective preferences of Mandarin-speaking adults who received the FSP coding strategy, at upgrade from the CIS + coding strategy. METHODS: Thirteen Mandarin-speaking subjects were tested at switch-over from CIS + to the FSP coding strategy ~1-month after switch-over, 2-months after switch-over, and 3 months after switch-over with the Mandarin Hearing in Noise Test (M-HINT), the Mandarin Tone Identification in Noise Test (M-TINT), and a visual analogue scale assessing Sound and Speech Assessment (SSA). RESULTS: There were no significant differences in the M-HINT between presentation levels (62 dB SPL vs 65 dB SPL), over time, nor when compared to the CIS + coding strategy. Tone perception improved significantly over time with the FSP coding strategy. Subjects rated the FSP coding strategy with the OPUS 2 as significantly more 'full' and 'rich' than with the CIS + coding strategy after 3-months.

PMID- 27701968 TI - A Systematic Review of Submaximal Cycle Tests to Predict, Monitor, and Optimize Cycling Performance. AB - Finding the optimal balance between high training loads and recovery is a constant challenge for cyclists and their coaches. Monitoring improvements in performance and levels of fatigue is recommended to correctly adjust training to ensure optimal adaptation. However, many performance tests require a maximal or exhaustive effort, which reduces their real-world application. The purpose of this review was to investigate the development and use of submaximal cycling tests that can be used to predict and monitor cycling performance and training status. Twelve studies met the inclusion criteria, and 3 separate submaximal cycling tests were identified from within those 12. Submaximal variables including gross mechanical efficiency, oxygen uptake (VO2), heart rate, lactate, predicted time to exhaustion (pTE), rating of perceived exertion (RPE), power output, and heart-rate recovery (HRR) were the components of the 3 tests. pTE, submaximal power output, RPE, and HRR appear to have the most value for monitoring improvements in performance and indicate a state of fatigue. This literature review shows that several submaximal cycle tests have been developed over the last decade with the aim to predict, monitor, and optimize cycling performance. To be able to conduct a submaximal test on a regular basis, the test needs to be short in duration and as noninvasive as possible. In addition, a test should capture multiple variables and use multivariate analyses to interpret the submaximal outcomes correctly and alter training prescription if needed. PMID- 27701969 TI - State of the Science-Ultraendurance Sports. AB - Participation in ultraendurance sports has been increasing in recent years. This participation growth has been associated with an increase in research focused on such events. While the total amount of research related to these sports remains relatively small compared with other sports, the research growth is encouraging. New sources for research funding for ultraendurance sports should advance the science. In addition to continued opportunities with observational studies, promising areas of investigation remain for experimental studies and research that uses ultraendurance-sport environments as models for studies relevant to wider populations. Insight into the breadth of research opportunities in ultraendurance sports can be gained by reviewing the abstracts published online in the International Journal of Sports Physiology and Performance from the annual Medicine & Science in Ultra-Endurance Sports Conference that took place this year in Chamonix, France. PMID- 27701984 TI - Erratum. PMID- 27701970 TI - Sleep and quality of life in people with ileal conduit. AB - OBJECTIVE: The aim of this study was to determine the sleep quality and the association between sleep quality and quality of life in people with ileal conduit. MATERIALS AND METHODS: A descriptive and cross-sectional design was adopted. The study sample comprised 111 people with ileal conduit operated on in urology clinics in a state hospital between January 2011 and May 2014. Six months after the operation, they were called by telephone to participate in the study. Data for the study were collected using a questionnaire form, the Pittsburgh Sleep Quality Index (PSQI) and the Stoma Quality of Life Scale (SQLS). RESULTS: The mean +/- SD total PSQI score of the people with ileal conduit was 10.20 +/- 2.95, mean total score of SQLS was 43.63 +/- 7.21, mean Work/Social Function domain score was 37.27 +/- 5.80 and mean Stoma Function domain score was 50.0 +/- 12.56. The total sleep quality had a low degree of negative correlation with total SQLS score, a medium degree of negative correlation with Work/Social Function (r = -0.327, p < .001) and no correlation with Stoma Function (r = 0.096, p > .001). People using a night drainage system had higher sleep quality. CONCLUSIONS: This study determined that quality of life and sleep deteriorate in people with ileal conduit. The quality of life decreases when the sleep quality is poor, and decreased quality of life affects quality of sleep in people with ileal conduit. PMID- 27701985 TI - Micro/nanoencapsulation of essential oils and fragrances: Focus on perfumed, antimicrobial, mosquito-repellent and medical textiles. AB - Herbal products have been widely used due to good antimicrobial, fragrance and medical properties. Essential oils and fragrances can be applied on the textile substrates as micro/nanocapsules to prolong lifetime by controlling the release rate. The present review tries to give a general overview on the application of micro/nanoencapsulated essential oils on the textile substrates to achieve aromatherapy textiles. These are divided into four diverse categories as the following: antimicrobial, perfumed, mosquito-repellent and medical textiles. The reports in this field revealed that the encapsulation technique plays an important role in the finishing of plant extracts on the textile substrates. It is also anticipated that aromatherapy textiles have to be developed in the new fields such as multifunctional textiles having wound-healing, antimicrobial and fragrant properties. PMID- 27701986 TI - Predictive validity of the ACC/AHA pooled cohort equations in predicting residual specific mortality in a national prospective cohort study of adults in the United States. AB - OBJECTIVE: The predictive validity of the Pooled Cohort risk (PCR) equations for residual-specific mortality (deaths not resulting from the 9 leading causes of death) among a national sample of U.S. adults has not previously been evaluated, which was the purpose of this study. METHODS: Data from the 1999-2010 National Health and Nutrition Examination Survey were used, with participants followed up through 31 December 2011 to ascertain mortality status. The analyzed sample included 11,171 cardiovascular disease-free adults (40-79 years of age). The 10 year risk of a first atherosclerotic cardiovascular disease (ASCVD) event was determined from the PCR equations. RESULTS: For the entire sample, 849,202 person months occurred with an incidence rate of 0.29 (95% CI: 0.25-0.33) residual specific deaths per 1,000 person-months. The unweighted median follow-up duration was 72 months. For all analyses, ASCVD risk score (via the PCR equations) was significantly associated with residual-specific mortality. In a fully adjusted model including moderate-to-vigorous physical activity (MVPA), obesity, age (yrs; continuous measure), gender (male/female) and race-ethnicity (Mexican American, non-Hispanic white, non-Hispanic black and other) as covariates, those with an ASCVD >= 20 (vs. < 20) had a 91% increased hazard of residual-specific death during the follow-up period (HR = 1.91; 95% CI: 1.10-3.31). Expressed as probability, there was a 66% chance that those with ASCVD >= 20 (vs. < 20) would have a residual specific-death during the follow-up period. CONCLUSION: The 10 year predicted risk of a first ASCVD event via the PCR equations was directly associated with residual-specific mortality among those free of cardiovascular disease (CVD) at baseline, providing evidence of predictive validity of the PCR equations among this national sample of U.S. adults. PMID- 27701987 TI - Efficacy and safety of bladder hydrodistension for decreased bladder capacity induced by intravesical BCG therapy. AB - OBJECTIVE: Intravesical BCG therapy is widely used for the treatment of high risk, non-muscle-invasive bladder cancer. Among various reported side-effects, decreased bladder capacity is a serious side-effect that significantly worsens patients' quality of life. This article reports the efficacy and safety of bladder hydrodistension (BHD) in six patients with seriously decreased bladder capacity caused by BCG treatment. METHODS: Six patients with low bladder capacity (<100 ml in voiding diaries) and complaint of grade 3 irritative symptoms were diagnosed with decreased bladder capacity and treated with BHD. Alleviation of symptoms was defined as medication being discontinued or reduced after BHD. RESULTS: Five patients were male and one was female, and the mean age was 67.7 years. The mean interval between the last transurethral resection and BCG therapy was 26.0 days. Before BHD, all patients had been treated with antibiotics, anticholinergics and non-steroidal anti-inflammatory drugs (NSAIDs). The median bladder capacity before treatment was 40 ml (range 30-100 ml), and the median capacity increased to 200 ml (175-250 ml) within 2 weeks following BHD therapy. Four patients stopped NSAID use and three patients stopped anticholinergic use. One patient needed total cystectomy for recurrent symptoms. With a median follow up period of 32 months, the bladder capacity remained stable without symptomatic deterioration in the remaining five patients. There was neither tumor spread nor disseminated tuberculosis infection. CONCLUSIONS: BHD appears to be an effective treatment option in patients with severely decreased bladder capacity. Its efficacy and safety were acceptable. PMID- 27701988 TI - Effect of particle size on oral bioavailability of darunavir-loaded solid lipid nanoparticles. AB - The present investigation aimed to study the effect of particle size of solid lipid nanoparticles (SLNs) on oral bioavailability of darunavir. High pressure homogenisation technique was used to prepare SLNs. Three different sized SLNs loaded with darunavir were developed with mean particle sizes of around 100 nm, 200 nm and 500 nm, respectively. The in vivo pharmacokinetics in rats showed a significant increase in oral bioavailability of darunavir from all the three formulations in comparison to plain drug suspension and reference tablet. The results revealed insignificant difference between SLNs of 100 and 200 nm and these had significantly higher bioavailability in comparison to SLNs of 500 nm. However, more number of homogenisation cycles is required for obtaining 100 nm and thus we selected 200 nm as an optimum size for oral bioavailability enhancement of darunavir. The optimised SLN formulation was stable for a period of 6 months at 25 +/- 2 degrees C/60 +/- 5% relative humidity (RH). PMID- 27701989 TI - Promoting excellence in care. AB - Welcome to Nurse Researcher. This year's annual RCN International Nursing Research Conference was held recently in Cambridge, UK. The event, which attracted over 500 delegates from a range of diverse and academic settings across the world, brought together nurses and other healthcare professionals to promote and develop nursing knowledge. Over 200 papers and poster presentations covered a wide range of topics in nursing and healthcare research, including: issues in research methodology; education; theoretical perspectives; transcultural nursing; evidence-based practice; employment issues; and research governance. In addition to concurrent sessions and posters, many symposia, workshops and other fringe and networking events offered opportunities for sharing good practice and research collaboration. Next year's conference will be held in Belfast, Northern Ireland, UK from Tuesday 8 to Friday 11 March 2005. For more information visit: www.man.ac.uk/rcn/research2005.

PMID- 27701993 TI - Mentally disordered offenders in Sweden: differentiating recidivists from non recidivists in a 10-year follow-up study. AB - BACKGROUND: Forensic psychiatric patients present a challenge as they manifest severe mental disorders together with criminal behaviour. There are well-known risk factors for criminal behaviour in the general population, yet knowledge of what predicts reconviction in the Swedish forensic population in the long-term perspective is still insufficient. AIMS: The study aims to (1) describe background and clinical characteristics of forensic psychiatric patients in a 10 year follow-up, (2) analyse risk factors associated with recidivism, and (3) test the predictive validity of risk factors for general and violent criminality. METHODS: Detailed information on all offenders from the Malmo University Hospital catchment area sentenced to forensic psychiatric in-patient treatment from 1999 2005 (n = 125) was collected. Court decisions were collected up until the end of 2008 (median follow-up time = 6.2 years, range = 0.6-9.7 years). RESULTS: Relapse in general crime (n = 30) was predicted by low educational attainment, mental disorder in a first degree relative, and low age at first sentenced crime. Relapse in violent crime (n = 16) was predicted by low educational attainment and low GAF scores. Patients with a restriction order were less likely to relapse in both crime categories. CONCLUSIONS: Signs of childhood adversities together with early debut in criminality appeared as important risk factors for general and violent recidivism. Forensic psychiatric treatment combined with a restriction order was demonstrated as a protective factor against recidivism, suggesting that the risk of recidivism is strongly related to the level of supervision. Although the low number of recidivism cases is highly desirable, it unfortunately reduces the power of the analyses in this paper.

AB - Molecular studies have shown metformin to have a promising effect in lymphoma; however, there is lack of studies translating this effect into clinical settings. This was a case-control study to assess the clinical effect of metformin in diabetic diffuse large B-cell lymphoma (DLBCL) patients. Case subjects were diabetic on metformin with a new diagnosis of DLBCL. A total of 24 case subjects were identified, and for each case a control was matched. Outcomes of this study were to assess overall response rate, complete remission rate, progression free survival, and overall survival between the two groups. There was a significant increase in overall response rate, complete remission rate, and improved progression free survival in the metformin group compared to the control group, however, no significant overall survival difference was observed. Metformin use might be associated with an improved response rates and progression-free survival in diabetic DLBCL patients. PMID- 27702014 TI - Personal experiences of designing questionnaires.

PMID- 27702066 TI - Rouleau version of the Clock Drawing Test: age- and education-adjusted normative data from a wide Italian sample. AB - OBJECTIVE: The Clock Drawing Test (CDT) is widely used as a screening tool for discriminating cognitively normal individuals from patients with mild dementia. The aim of present study was to provide normative values for a 10-point quantitative scoring system proposed by Rouleau and colleagues (1992), including CDT total score and subscales score assessing representation of clock face (RC), layout of numbers (LN), and position of hands (PH), in a large sample of Italian healthy individuals. METHOD: Eight hundred and seventy-two Italian healthy participants (483 women; age range 20-94 years) with educational level from primary school to university underwent CDT and Mini Mental State Examination (MMSE). RESULTS: Multiple linear regression analysis revealed that age and education significantly influenced CDT total score and its subscale scores. Moreover, a significant effect of gender was found only in RC subscale. From the derived linear equation, a correction grid for raw scores was built. Inferential cut-off values were estimated using a non-parametric technique and equivalent scores (ES) were computed. Correlation analysis showed a weakly significant correlation between adjusted CDT total score and adjusted MMSE scores. CONCLUSIONS: The present study provided normative data for the Rouleau and colleagues version of CDT in an Italian sample, useful for clinical and research purposes. PMID- 27702158 TI - Fighting off 'flu. AB - All manner of coughs, colds and sneezes are passed off as 'the 'flu' but anyone who has experienced the dreadful spirit-sapping incapacity of the true virus will know that those who proclaim to have it while remaining upright misunderstands its true nature. The aching limbs, the lethargy, the headaches - it's like being crushed by a barn door, while having a nose running like a tap and a cough to wake the dead. If you're young and fitish, you emerge from the experience a few days later weakened and washed out, but essentially alive. If you're an older person, however, or one whose immunity is already compromised, the consequences can be fatal. And the threat is particularly acute in epidemic years: 29,000 died from 'flu in 1989/90, although even in an 'average' year, 12,000 deaths are linked to 'flu activity. PMID- 27702159 TI - ? AB - There is concern among researchers in the United States that some communities predominantly settled by members of minority ethnic groups have lower levels of nursing home provision than the average for the society as a whole. Similarly, there is some evidence that elders from such communities may be 'steered' towards segregated facilities. Data from the 1990 US Census of Population and the 1994 Illinois Long-Term Care Facility Survey were analysed to see what patterns emerged for the Chicago area. The results showed that both African American and Latino nursing home residents tend to be found in their own neighbourhoods, although overall Latinos demonstrated the greater mobility. 19 references.

AB - Osteoarthritis (OA) is a common and often disabling condition affecting older adults. Treatment using anti-inflammatory drugs (NSAIDs) often contributes to morbidity ( 1 ). It is a common reason for people seeking help from primary care ( 2 ). However, unfortunately management approaches often reflect the ageist view that OA is an inevitable consequence of ageing. PMID- 27702163 TI - Patient recruitment and retention strategies in randomised controlled trials. AB - Evidence-based practice has become a by-word for health care in the 1990s. However, the idea of founding practice on evidence rather than anecdote or tradition has a much longer history. In the 1970s, Cochrane ( 1 ) was already arguing the need for the widespread use of randomised controlled trials (RCTs) to inform practice, not only with a view to identifying the most effective clinical treatments, but also the equitable and economical means of utilising those treatments.

AB - Randomised controlled trial (RCT) research designs are generally considered to be the most rigorous way of determining whether a cause and effect relationship exists between an intervention/treatment and outcome, and for assessing the effectiveness, including cost- effectiveness, of an intervention or treatment ( 1 ). Studies employing such designs play an important role in nursing, as in all aspects of healthcare, because of the need to establish the evidence base for practice and to be able to predict the likely consequences of certain events and interventions under given conditions. This is important not only with respect to patient care but also to inform policy, planning and allocation of resources( 2 ). PMID- 27702166 TI - Focus group interviews as a methodology. AB - Focus groups are a form of group interview used widely in social science research. It is a methodology that has also been applied in a number of areas of healthcare study, particularly in health promotion and consumer satisfaction. First described by Bogardus in 1926 ( 1 ). focus groups fuse the principles of qualitative research and group process theory.

Moreover, in one town with a large ethnic minority (15.4 per cent of the population) GPs informed me that they believed that women of South Asian descent with menorrhagia had particular difficulties in obtaining treatment, mainly because of the shortage of female doctors ( 2 ). PMID- 27702169 TI - The randomised controlled trial: a critique. AB - Traditionally, health care has been based on historical legacy, personal treatment preferences and ritual. Indeed in the present day, some health professionals persist not only in practising clinical interventions that are known to be ineffective, but also fail to introduce others that tire known to have good outcomes, resulting in inescapably huge variations in practice and treatments ( 1 ). PMID- 27702170 TI - ? AB - This paper represented a collaborative project between researchers in Mexico and the USA, using Roy's Adaptation Model as its theoretical basis. A sample of 50 older women drawn from two socially and economically disadvantaged areas in Mexico formed the sample. A questionnaire was used to explore both the women's roles in society and their participation in exercise. The findings indicated that 40 per cent of the sample were contemplating some type of exercise. The authors found this total surprisingly high, as exercise has not been a social norm for older women in this section of society. The opportunities for health promotion are discussed. 21.

AB - This book aims to show readers that behaviours in people with dementia tend to be wrongly or poorly described and that this can lead to a misunderstanding of how best to understand or respond to both the behaviours and the person. The author makes a strong case for greater observation and assessment of a range of behaviours and their influencing factors. He also argues that interventions must be underpinned by a person-centred approach and with empathy for the subjective experience of people with dementia. The book should appeal to nurses, care assistants and other health care professionals as well as people working in the voluntary sector. PMID- 27702173 TI - Letters.

There is good care practice which needs to be highlighted, praised and shared for the benefit of the public and the profession. However, there is also poor, underdeveloped and entrenched practice about which we sadly hear in the media. This has concerned me for some time ( Morgan 1992 ). There needs to be a mechanism whereby nurses can share practice which is person-centred, high quality and offers the best to the public. I see the RCN, and particularly the forums, as the professional organisation to take this forward. PMID- 27702180 TI - Tai Chi for older people.

AB - We are pleased to introduce this issue of Nurse Researcher about research governance and ethics when interest in these matters is so high.

PMID- 27702208 TI - Wasting time? AB - In February the Department of Health launched guidance designed to help local health and social care agencies introduce a single assessment for older people. Although the concept of a single assessment is set out in more detail in the National Service Framework for Older People, the overall aim, according to the Department of Health (2002) is to: 'Ensure that older people receive appropriate, effective and timely responses to their health and social care needs, and that professional resources are used effectively. In pursuit of these aims, the single assessment process should ensure that the scale and depth of assessment is kept in proportion to older people's needs; agencies do not duplicate each other's assessments; and professionals contribute to assessments in the most effective way.' PMID- 27702209 TI - Side rails: the need for appropriate assessment. AB - Side rails, or 'cot-sides' as they have been widely known, have always been used so freely both in hospitals and nursing homes since I started my career in 1981 that, prior to reading this article, I never considered them as anything more than safety equipment that prevents a patient falling out of bed. The thought of careful risk-assessment and gaining consent prior to their use had never crossed my mind. PMID- 27702210 TI - Things can only get better.

AB - Most professionals working with older people favour a 'needs led' assessment process in which the individual's needs form the agenda for action. It does not prove easy, however, to ignore professional and organisational agendas when assessing patients' needs. In this fascinating experimental study, the discharge arrangements made by three multidisciplinary teams were reviewed. The team led by an occupational therapist arranged the most occupational therapy services and equipment, and their patients received the most home care. The team led by a social worker referred the most patients for care assessment and their patients received the greatest range but not the greatest amount of services. The nurse led team was least likely to refer patients for care assessment and their patients received the least services after discharge. 27 references. PMID- 27702212 TI - A moment in history.

The hardback version has for the past few years been an excellent source of knowledge on the many different approaches to action research in a wide range of contexts and settings. The original book is by no means a beginners' compendium; action research is a broad church, but without an understanding of how it compares with other research strategies, the niceties of some of the variants can be elusive. For example, some would argue that action research is necessarily underpinned by critical theory and that it is always conducted in the participatory, transformative mode. Looking down the list of chapters, one would be forgiven for thinking this to be so, but a much closer scrutiny demonstrates that action research has a long history, along a continuum of 'highly theoretical' to 'very pragmatic' and in many fields including education, health care, social situations and organisations.

There are a number of issues which are touched upon, but not really explored, for example, triangulation. Now this is a large topic in itself, and it would be unreasonable to suggest that a slim volume such as this can cover all topics relevant to social science/nursing research, nor that any author should try to do this. What this does highlight, though, is that, although this book may be a useful point of departure, the students will still have to read widely and be in a position to compare and contrast sources to justify their choices of methodology and methods.

AB - We present a mathematical model (a) for the infection of a honey bee colony with Nosema ceranae. This is a system of five ordinary differential equations for the dependent variables healthy and infected worker bees in the hive, healthy and infected forager bees, and disease potential deposited in the hive. The model is then (b) extended to account for increased forager losses, e.g. caused by exposure to external stressors. The model is non-autonomous with periodic coefficient functions. Algebraic complexity prevents a rigorous mathematical analysis. Therefore, we resort to computer simulations in addition to some analytical results in the constant coefficient case. We investigate each of the two stressors (a) and (b) individually and jointly. Our results indicate that the combined effect of two stressors, both of which can be tolerated by the colony individually, might lead to colony failure, suggesting multi-factorial causes behind losses of honey bee colonies.

Caring has become more demanding and more stressful and this is recognised by both authors: Tanya Arroba and Leslie Bell, who have many years of experience in care of the adult.

AB - This paper summarises some of the findings of a major research project, funded by the English National Board, on the nurse's role in rehabilitation. An extensive literature review using a wide range of databases was conducted in order to elucidate the nurse's role in patient education. This approach was supplemented by curriculum analysis based on course documentation drawn from a range of pre registration diploma and degree courses, together with a range of post registration courses. The conclusion drawn is that while the literature argues for the central importance of patient education in the rehabilitation process, curriculum analysis suggests that nurses are not adequately prepared for this aspect of their role. 98 references.

AB - Non-suicidal self-injury (NSSI) is a complex behaviour, routinely engaged for emotion regulatory purposes. As such, a number of theoretical accounts regarding the aetiology and maintenance of NSSI are grounded in models of emotion regulation; the role that cognition plays in the behaviour is less well known. In this paper, we summarise four models of emotion regulation that have repeatedly been related to NSSI and identify the core components across them. We then draw on social cognitive theory to unite models of cognition and models of emotion in developing a new cognitive-emotional model of NSSI. Our model articulates how emotion regulation and cognition can work in concert to govern NSSI, and offers several new research questions that can be addressed within this framework.

AB - As the government presses ahead with its plans for NHS reform, there has been growing speculation about the possibility of an increased role for the voluntary sector in the management and delivery of health care. According to one source ( Hinscliff 2002 ), patients' groups are calling for a greater say in running hospitals, arguing that they possess the specialist skills required to ensure that services are patient-centred rather than organised for the convenience of staff. Such proposals are said to be attracting the interest of health secretary Alan Milburn, who is keen to incorporate patients' interests into the heart of the NHS following scandals such as those at the Bristol Royal Infirmary. PMID- 27702253 TI - Longer shift, better care? AB - Twelve-hour shifts are highly contentious in nursing, with mixed opinions about whether there are any real benefits for patients, staff or management. Research has highlighted issues such as tiredness, reduced teaching opportunities and even the possibility of a negative effect on staff recruitment ( Todd et al 1993, Turner et al 1987 ). However, our recent pilot study demonstrated potential benefits ( Bloodworth et al 2001 ). This article aims to take the debate a step further and suggests that 12-hour shifts can actually improve the implementation of the newNational Service Framework for Older People in a hospital setting ( DoH 2001 ). We are aware that these are controversial arguments and hope to provoke thought and discussion. PMID- 27702254 TI - ? AB - Nurses are constantly required to imagine what patients are thinking or feeling in circumstances beyond their own experience. First-hand reports can help to increase awareness of potential patient needs. In this subjective account of a confusional state caused by acute renal failure, a retired psychiatrist (aged 79) recounts his own memories of being ill and attempts to relate them to events that occurred during his hospital stay.

AB - Strong quantitative research methods are one of the patient's strongest safeguards against dangerous bias and prejudice on the part of researchers. In addition, the evidence that algorithmic decision making outperforms 'clinical' or other human decision making by a fair margin is very strong. It is therefore sad that statistics are so feared by students, and in general are not well taught. Most books are sound on the elementary parts of statistics, but start to become difficult when more abstract concepts are covered. This book is in that tradition.

As the authors point out, when the book was first published in the l970s, evaluation of social programmes was not well-established - a situation which is very different now with evaluation research embedded throughout all types of public and non-public organisations and on a global basis.

AB - Reworking Qualitative Data is, to say the very least, an interesting and relatively novel text. For many nurse researchers (including me), this will be unfamiliar territory and a refreshing addition to the staple diet of research methodology books currently available. As the title suggests, the book explores the possibility and principles of undertaking secondary analysis of qualitative data sets. As the author acknowledges, secondary analysis of pre-existing statistical data sets has been commonplace for over the past 30 years, whereas the secondary analysis of qualitative data sets is still very much in its infancy. Given the novelty of this approach this book serves as a useful introduction for anyone considering the use of qualitative secondary analysis. It is packed with thought-provoking and interesting ideas and attempts to cover all the bases in terms of defining the methodology, discussing the types of qualitative secondary analysis, as well as attempting to grapple with the thorny epistemological and ethical and legal issues. The author even offers modi operandi for those wishing to undertake secondary analysis of a pre-existing data set. PMID- 27702265 TI - Introduction.

AB - In this paper, Helena Priest describes and justifies a phenomenological research method that may be used to explore complex and nebulous concepts relevant to nursing and health care, for example, the concept of 'caring'. The history and development of Husserlian phenomenology are outlined, followed by an account of the use of phenomenology within nursing research. Tensions inherent in the use of Husserlian phenomenology in nursing research are noted. A phenomenological approach to data analysis, designed to address some of these tensions, is described and compared with several well-established phenomenological analysis strategies. Issues of reliability, validity and generalisability are discussed, as are limitations in the use of the approach, before conclusions relevant to healthcare researchers are drawn. PMID- 27702271 TI - Interaction as an ethically sensitive subject of research. AB - In this paper, Hanna Maijala, Paivi Astedt-Kurki and Eija Paavilainen discuss ethically sensitive family nursing research. A study of the interaction between caregivers and families expecting a child with an abnormality is used as an example: 29 parents and 22 caregivers were interviewed. Complementary data were obtained from essays written by five parents. This sensitive subject required discretion, especially when the parents were first asked to participate in the study, and during subsequent interviews. From the perspective of the data analysis, it was essential to obtain the informants' personal experiences unaltered. The constant comparative method of grounded theory was used to analyse the data. In the study findings, special attention was paid to presenting the results truthfully, while safeguarding the informants' anonymity. In conclusion, the ethical questions related to the subject of the study are discussed from the point of view of both the participant and the researcher. PMID- 27702272 TI - Commentary. AB - When I facilitate sessions that explore ethical aspects of research, one of the first activities I ask group members to do is to consider the rights which they believe they should have as potential research participants. Very quickly, and without exception, they are able to identify a range of issues from the right to confidentiality, through to freedom from harm and the right to know why the research is being undertaken. Given that these issues can so easily be identified, it could be tempting to assume that all research would be conducted in an ethical manner. Unfortunately, history reveals many horror stories of actions carried out in the name of research. Even today, questionable aspects of research are brought to light. The focus on research ethics within this edition of Nurse Researcher is thus a timely reminder of the key issues that need to be addressed. PMID- 27702276 TI - Illustrating the ethical dimensions of action research. PMID- 27702278 TI - The ethics of research with children. AB - In this article, the focus of which is research with children, Peter Allmark considers ethical issues in relation to both quantitative and qualitative research. Guidelines on the ethical conduct of research with children focus primarily on issues to do with quantitative research (e.g. RCPCH 2000 ). For this reason, this article tries to draw out points of particular importance to qualitative research. It begins with some assumptions and points of terminology, before briefly describing the history of the development of ethical regulation. It then discusses specific ethical issues that arise when researching with children. These are placed into three main categories: scientific validity, welfare, and rights and dignity. PMID- 27702279 TI - Editorial. AB - Ethical issues in research have, quite rightly, come under increasing scrutiny in recent years. In the UK, all research involving human subjects, patients, human samples, patient data, or NHS staff or facilities must take into account the requirements of the Research Governance Framework for Health and Social Care ( DoH 2001 ). The Central Office for Research Ethics Committees (COREC), working on behalf of the Department of Health in England, co-ordinates the development of operational systems for Research Ethics Committees (RECs) in the NHS, and manages Multicentre Research Ethics Committees (MRECs) in England. Additionally, COREC now provides a strategic overview of Local Research Ethics Committees (LRECs). As part of their ethical review processes, LRECs will now require evidence of independent peer review, commensurate with the scale of the research. This will inevitably impact on the timescales for approval of projects, which should be taken into account when writing proposals and planning research. Recent guidance has included a definition of a research 'site': 'the geographical area covered by one Health Authority, whether the research is based in institution(s) or in the community', while multi-centre research is defined as: 'research taking place within the boundaries of two or more research "sites".' Other developments include changes affecting procedures to NHS Research Ethics Committees. Policy and guidance is continually developing and further information can be found on the Central Office for Research Ethics Committees' website: http://www.corec.org.uk/.

The event is organised under the auspices of the RCN Research Society, in partnership with their appointed RCN events manager and the RCN R&D Co ordinating Centre. Now an annual international event, there is a slow but steady increase in the number of international delegates. The principal aim of the conference is to share the best in nursing and health care research. It is always an excellent networking opportunity. A secondary aim is to nurture and support the next generation of researchers. PMID- 27702285 TI - Awards. PMID- 27702284 TI - The final hurdle: preparation for the phd viva examination. AB - The viva examination is the culmination of the PhD process. However, it is important to prepare carefully for this final and important hurdle. In this paper, Barbara Jack looks at the different stages of the viva examination, which include undertaking a careful and systematic preparation. This preparation involves gaining a comprehensive awareness of the university procedure for the viva, researching examiners, and considering the value of having a mock viva. The paper explores the actual viva and makes suggestions to deal effectively with questioning from the examiners. Finally, the results of the viva and steps needed to address corrections are discussed. PMID- 27702286 TI - ?

PMID- 27702289 TI - The NHS Plan - funding nursing care. AB - The NHS Plan ( DoH 2000 ), published last year, emphasises improved care for older people. Key within it is the proposal that older people in all settings will receive free NHS nursing care by October this year. This is good news for older people living in nursing homes and who are at present paying for their nursing care. The Royal Commission on long term care ( 1999 ) recommended that all personal and nursing care should be funded, but this has been rejected by the government, which has said nursing care, but not personal care, will be free, thus creating an artificial divide between the two. As nurses who work with older people will know, integration of services and care approaches are necessary to maximise the older person's potential, and respond to their expressed needs and wishes.

AB - Inadequate oxygenation impairs the wound healing process, and so ensuring optimal delivery of oxygen to the tissues is likely to be an important issue in promoting the healing of venous leg ulcers. This study used a convenience sample of 31 patients (with an age range of29to86years: mean age59.8years) who were attending vascular clinics on the west coast of the USA. Measurements indicated that control of peripheral circulation and tissue oxygenation may be impaired in people with venous ulcers. Leg elevation, sitting and standing decreased wound perfusion, and so the authors suggest that more research is necessary to investigate these relationships in more detail. 53 references. PMID- 27702297 TI - The relationship of hardiness and depression to disability in institutionalized older adults. AB - Studies of depression among residents of long term care facilities are a familiar component of the research literature, but the concept of 'hardiness' is less familiar on this side of the Atlantic. Studies have suggested that health-related hardiness predicted the degree of disability experienced by older people subjected to similar levels of stress. In this study, a lecturer at Yale University explored the relationship of hardiness and depression to disability in a sample of 58 older people who were residents in a nursing home. The results indicated that the psychological variables of hardiness and depression contributed more than did health status and length of stay to explaining levels of disability. The author concludes by suggesting therapeutic approaches which may be beneficial. 56 references.

AB - The aim of this team education project was 'to provide multidisciplinary education in the clinical environment and to directly influence practice'. The education programme was carried out in a continuing care unit for older people situated in inner London. The education programme consisted of twice-weekly, ward based reflective groups held over seven weeks. The theme chosen for exploration in the group was that of bereavement. Although the intention had been to include participants from a wide range of backgrounds, there proved to be little involvement from non-nursing staff. The evaluation interviews conducted with group members were generally positive, but all the interviewees said that the programme had not changed the way they worked with residents. The authors argue that a psychoanalytic approach is useful when studying organisational behaviour in a stressful environment. 26 references. PMID- 27702303 TI - ? PMID- 27702302 TI - ?

The two research questions were (i) what are the patterns of hope manifested by older adults after a stroke? and (ii) what are the factors associated with their patterns of hope after the stroke? Some of the hope themes which emerged from analysis of the transcripts, such as 'positive anticipation' and 'faith in God', have been previously identified by earlier researchers. Other themes, such as 'previous abilities' and 'mobility' are claimed to be missing from the (mostly American) literature on hope.

The RCN has lobbied consistently for comprehensive assessment leading to appropriate care from a range of professionals for all older people who often have inter-related health and social care needs. Unfortunately, nursing's holistic nature can be undermined by managers and service providers who seek to contain costs, even though nurses' distinct contribution to the overall care of older people is cost-effective and can result in significant positive patient outcomes.

This Commentary discusses in vitro activation (IVA), a technique that activates dormant ovarian follicles so that these follicles can become mature oocytes for fertilization. There is considerable evidence that mechanical signaling plays an important role in oocyte maturation and survival; manipulation of the mechanical environment is a key component of the IVA process. IVA acts on existing follicles and does not promote neo-oogenesis, which likely contributes little to the primordial follicle pool in the adult. CONCLUSIONS: Several women with primary ovarian insufficiency who underwent the IVA procedure have achieved live births. IVA might also be applicable to women with pathological diminished ovarian reserve and those with physiological diminished reserve due to natural aging. Cancer patients with cryopreserved ovarian tissue also might benefit from IVA. Based on future studies, IVA could prove to be a revolutionary tool for assisted reproduction.

The sample consisted of five registered mental health nurses, who all worked on the same hospital ward in the north of England. Semi-structured interviews were used to elicit the key concepts utilised by the participants, and analysis of the transcripts identified four core variables: a humanistic code (treating clients as individuals); pragmatic knowledge (specific interventions); interpersonal relations (human interaction); and the nurse as a utilizer (organisational skill). The issue of hope held major importance. As one of the nurses said, 'When I start to feel a little hopeless myself, I make sure that this is not communicated to the client'. 64 references.

Although mostly excellent, I would just like to point out that greasy emollients such as white soft paraffin/liquid paraffin 50/50 or zinc and castor oil are not recommended for use with incontinence pads. This is because the 'barrier' effect, while supposedly protecting the skin, also forms a moisture resistant layer on the surface of the pad which prevents the absorption process, and can therefore have the opposite effect of making the skin wetter and more prone to soreness.

AB - A consultation exercise on the future of services for older people which I undertook recently for a local authority social services committee, revealed - predictably - a wide diversity of opinions. But there were deep variations, too, in the abilities of the stakeholders we were consulting to put across their points of view, and I saw it as an important part of my role to try to compensate for these differences when listening to people who clearly had difficulties in communication. Carers and relatives, groups who often go unheard, were, in this situation, both articulate and in most cases well-organised. I had only to advertise my availability for their point of view to be expressed powerfully, by individuals and groups, orally and in writing, some of it moderately expressed, some of it put across with passion, even anger.

PMID- 27702350 TI - ? AB - Staff drawn from 15 nursing homes in Hillsborough County, Florida, formed the sample for this study. Questionnaire data provided demographic and managerial information. This indicated that the turnover rate in the previous six months was 23 per cent, while for nursing assistants it was 45 per cent. Selected staff members from each nursing home were then asked to consider six previously developed case studies which had been designed to illustrate aspects of autonomy. Certified nursing assistants were more likely than registered nurses to believe that it is the home's responsibility to make choices for residents. 15 references. PMID- 27702352 TI - ? AB - A purposive sample of ten nurses working in an orthopaedic unit in eastern Canada were interviewed in order to explore their experiences of caring for older people suffering from acute confusion. All subjects reported that acute confusion was a 'regular occurrence', and that it is much worse in the evening and at night. The three strategies used for coping when patients became unmanageable and disruptive were sitters, medication and physical restraint. The latter was regarded as a last resort and would only be implemented with the permission of the patient's family. PMID- 27702351 TI - Learning by degrees. AB - The National Service Framework for Older People (DoH 2001a) clearly sets out the government's strategic intentions for the development of services to meet the health and social care needs of older people. In order to make these plans a reality, not only are fundamental changes required in the way health and social services are organised and delivered but also in the way in which nurses and allied health professionals are educated. PMID- 27702353 TI - Plans for networking.

I am still paid as a staff nurse but perform care assistant duties. Both nurses and carers are there to work together to meet patients' daily living, nursing, emotional and social needs so, in that sense, there is little difference. In fact I enjoy the freedom away from drug rounds, wound management and administration duties. I can get back to the heart of nursing: delivering direct care to patients.

We would consult the others, not with any confidence that they understood, but more from a sense of duty. Then we would do the deed - weekend trips to the coast, for example, or something radical like re-arranging the day room - and then brave the huffing that would persist until the prison man acclimatised to the new arrangements.

PMID- 27702368 TI - Out to pasture? AB - Nursing homes can provide space for the development of creative and dynamic nursing practice that should be celebrated. However, there is no doubt that negative attitudes towards nursing homes and the nurses who work in them persist. Comments such as 'what do you do all day, do you it drinking tea?' or 'isn't it depressing?' are common, and the opinion that nurses working in this setting 'probably couldn't get a job anywhere else' tends to be held by those who have never set foot inside a nursing home.

AB - Two large-scale studies commissioned by the Department of Health, one a longitudinal survey of people aged 65 or over admitted to residential and nursing homes, and the other a cross- sectional survey of homes for older people, formed the basis of this study. A detailed picture of care provision for older people with cognitive impairment is provided. Very few residents left care homes permanently after admission. Only 2 per cent had been discharged by 30 months after admission. Another important finding concerns mortality. About one third of the sample had died by six months after admission, while by 30 months almost two thirds had died. Overall the median length of stay of publicly funded residents was 18 months. 24 references.

AB - Similarities and differences between day hospitals, run by the NHS, and day centres, run by local authorities or charitable organisations, have been widely discussed in the literature of gerontology for many years. The authors of this paper have undertaken a single blind, randomised-controlled trial to compare rehabilitation outcomes in the two settings, which was published in 1999. This research project involved augmenting the staff of day centres by visiting therapists. In addition to quantitative findings, their project also generated much qualitative data from interviews with health service and social service staff which provides the thought-provoking content. The themes identified included the reluctance of some patients to accept referral to a day centre, and the difficulties associated with discharging patients. Positive aspects included the opportunity to share skills, knowledge and resources. 29 references. PMID- 27702379 TI - Basic needs of older people in hospital 'often ignored'.

AB - Ageing is associated with declines in several cognitive abilities including working memory (WM). The goal of the present study was to assess whether emotional information could reduce the age gap in the quantity and quality (precision) of representations in visual WM. Young and older adults completed a serial image recognition (SIR) task and a colour-image binding (CIB) task. Results of the SIR task showed worse performance for negative than neutral and positive images within the older group, hence enlarging the age gap in WM. In the CIB task, recall precision was lower in the old than young adults, showing an ageing decline in the quality of WM representations. Positive images tended to improve precision, but this boost was similar for both age groups. In sum, emotional content did not reduce the age gap in visual WM. PMID- 27702388 TI - Epidermal Growth Factor Induces Proliferation of Hair Follicle-Derived Mesenchymal Stem Cells Through Epidermal Growth Factor Receptor-Mediated Activation of ERK and AKT Signaling Pathways Associated with Upregulation of Cyclin D1 and Downregulation of p16. AB - The maintenance of highly proliferative capacity and full differentiation potential is a necessary step in the initiation of stem cell-based regenerative medicine. Our recent study showed that epidermal growth factor (EGF) significantly enhanced hair follicle-derived mesenchymal stem cell (HF-MSC) proliferation while maintaining the multilineage differentiation potentials. However, the underlying mechanism remains unclear. Herein, we investigated the role of EGF in HF-MSC proliferation. HF-MSCs were isolated and cultured with or without EGF. Immunofluorescence staining, flow cytometry, cytochemistry, and western blotting were used to assess proliferation, cell signaling pathways related to the EGF receptor (EGFR), and cell cycle progression. HF-MSCs exhibited surface markers of mesenchymal stem cells and displayed trilineage differentiation potentials toward adipocytes, chondrocytes, and osteoblasts. EGF significantly increased HF-MSC proliferation as well as EGFR, ERK1/2, and AKT phosphorylation (p-EGFR, p-ERK1/2, and p-AKT) in a time- and dose-dependent manner, but not STAT3 phosphorylation. EGFR inhibitor (AG1478), PI3K-AKT inhibitor (LY294002), ERK inhibitor (U0126), and STAT3 inhibitor (STA-21) significantly blocked EGF-induced HF-MSC proliferation. Moreover, AG1478, LY294002, and U0126 significantly decreased p-EGFR, p-AKT, and p-ERK1/2 expression. EGF shifted HF-MSCs at the G1 phase to the S and G2 phase. Concomitantly, cyclinD1, phosphorylated Rb, and E2F1expression increased, while that of p16 decreased. In conclusion, EGF induces HF-MSC proliferation through the EGFR/ERK and AKT pathways, but not through STAT-3. The G1/S transition was stimulated by upregulation of cyclinD1 and inhibition of p16 expression. PMID- 27702391 TI - Affect, Attachment, Memory: Contributions Toward Psychobiologic Integration. PMID- 27702392 TI - Selenium Supplementation Significantly Reduces Thyroid Autoantibody Levels in Patients with Chronic Autoimmune Thyroiditis: A Systematic Review and Meta Analysis. AB - BACKGROUND: Selenium supplementation may decrease circulating thyroid autoantibodies in patients with chronic autoimmune thyroiditis (AIT), but the available trials are heterogenous. This study expands and critically reappraises the knowledge on this topic. METHODS: A literature search identified 3366 records. Controlled trials in adults (>=18 years of age) with AIT, comparing selenium with or without levothyroxine (LT4), versus placebo and/or LT4, were eligible. Assessed outcomes were serum thyroid peroxidase (TPOAb) and thyroglobulin (TgAb) autoantibody levels, and immunomodulatory effects. After screening and full-text assessment, 16 controlled trials were included in the systematic review. Random-effects meta-analyses in weighted mean difference (WMD) were performed for 3, 6, and 12 months of supplementation in two different populations: one receiving LT4 therapy and one newly diagnosed and LT4-untreated. Heterogeneity was estimated using I2, and quality of evidence was assessed per outcome, using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines. RESULTS: In LT4-treated populations, the selenium group had significantly lower TPOAb levels after three months (seven studies: WMD = -271 [confidence interval (CI) -366 to -175]; p < 0.0001; I2 = 45.4%), which was consistent at six months (three studies) and 12 months (one study). TgAb decreased at 12 months, but not at three or six months. In LT4-untreated populations, the selenium group showed a decrease in TPOAb levels after three months (three studies: WMD = -512 [CI -626 to -398]; p < 0.0001, I2 = 0.0%), but not after 6 or 12 months. TgAb decreased at 3 months, but not at 6 or 12 months. Quality of evidence was generally assessed as low. Study participants receiving selenium had a significantly higher risk than controls of reporting adverse effects (p = 0.036). CONCLUSIONS: Selenium supplementation reduced serum TPOAb levels after 3, 6, and 12 months in an LT4-treated AIT population, and after three months in an untreated AIT population. Whether these effects correlate with clinically relevant measures remains to be demonstrated.

AB - Increasing evidence suggests that micro (mi)RNAs play important roles in various biological process. To evaluate the roles of miRNA in the porcine liver, we investigated the dynamic profiles of microRNAomes using liver tissue from pigs during the embryonic period (embryonic day 90), weaning stage (postnatal day 30), and adult stage (7 years old). A total of 186 unique miRNAs were differentially expressed during liver development. We also identified that 17, 13, and 6 miRNAs were specifically abundant at embryonic day 90, postnatal day 30, and at 7 years, respectively. Besides regulating basic cellular roles in development, miRNAs expressed at the three developmental stages also participated in regulating "embryonic liver development," "early hepatic growth and generating a functioning liver," and "energy metabolic processes," respectively. Our study indicates that miRNAs are extensively involved in liver development, and provides a valuable resource for the further elucidation of miRNA regulatory roles during liver development. PMID- 27702395 TI - Identification and quantification of adulteration in Garcinia cambogia commercial products by chromatographic and spectrometric methods. AB - Species of genus Garcinia are rich sources of bioactive constituents with antimicrobial, anticancer, anti-inflammatory, hepatoprotective and anti-HIV activities. Commercial products of Garcinia cambogia are used as anti-obesity drugs with increasing market demand. Because of the high price of its products, it can be adulterated with similar lower-priced species. This study was designed to develop and validate an accurate and efficient method for the detection of any adulteration (G. indica) in G. cambogia products. For this purpose, high performance liquid chromatography (HPLC) was used to analyse the ethanolic fruit rind extracts of G. cambogia and G. indica, their formulations of 0.5, 1, 2, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 95% G. indica with G. cambogia, and 11 G. cambogia commercial products. The analytical methods were validated by quality assurance parameters of linearity, sensitivity, precision and accuracy. Two marker peaks were detected in G. indica fruit extract, whereas G. cambogia did not show these peaks. The detected peaks were identified as anthocyanins; cyanidin-3-O-sambubioside and cyanidin-3-O-glucoside. In the study to determine the effect of pH and temperature on the stability of its anthocyanin content, HPLC analysis of G. indica extract showed the highest content at pH 1 and 50 degrees C. Using two different mobile phases, the limits of detection (LOD) for cyanidin-3-O-sambubioside and cyanidin-3-O-glucoside were 0.036 and 0.059, and 0.022 and 0.033 mg kg-1, respectively. Furthermore, the inter-day precision (< 3.2%) confirmed that the applied analytical method fulfils the required criteria of Association of Official Analytical Chemists (AOAC). From this study, it was found that the HPLC method used for the detection of adulteration in G. cambogia products is rapid and accurate. PMID- 27702397 TI - Isolation, Characterization, and In Vitro Culturing of Spermatogonial Stem Cells in Japanese Quail (Coturnix japonica). AB - We reported previously testis-mediated germline chimera production and characterization of germline stem cell-like cells from chicken testes. The present study aimed to establish an in vitro system for culture of quail spermatogonial stem cells (SSCs) for practical applications in germline preservation and transgenesis. Testicular cells (TCs) from juvenile (4 weeks old) or adult (8 weeks old) quail testis were isolated using sequential enzymatic digestion. The percentages of viability of isolated TCs were 91.00% +/- 2.12% and 88.00% +/- 1.87% in juvenile and adult testes, respectively, and immunohistochemical evaluation indicated the expression of integrin alpha-6 (ITGA6), GDNF family receptor alpha-1 (GFRA1), and Deleted in azoospermia-like (DAZL) in specific TCs. SSCs were purified by differential plating of TCs and then subjected to quantitative reverse transcription-polymerase chain reaction, which showed differential expression of SSC-specific, and germness and stemness related genes. Coculture of quail SSCs with mouse embryonic fibroblasts and Sertoli cells as a feeder layer resulted in the generation of stable SSC colonies and short-term cultivation, and the expression of SSC and germ cell markers was maintained during several passages of culture. Collectively, these results demonstrate the efficient isolation and characterization of quail SSCs and the suitability of Sertoli cells as a feeder layer for in vitro culture of quail SSCs. Quail SSCs will facilitate the production of germline chimeras and transgenesis. PMID- 27702396 TI - Calvarial Defect Healing Induced by Small Molecule Smoothened Agonist. AB - Hedgehog (Hh) signaling positively regulates both endochondral and intramembranous ossification. Use of small molecules for tissue engineering applications poses several advantages. In this study, we examined whether use of an acellular scaffold treated with the small molecule Smoothened agonist (SAG) could aid in critical-size mouse calvarial defect repair. First, we verified the pro-osteogenic effect of SAG in vitro, using primary neonatal mouse calvarial cells (NMCCs). Next, a 4 mm nonhealing defect was created in the mid-parietal bone of 10-week-old CD-1 mice. The scaffold consisted of a custom-fabricated poly(lactic-co-glycolic acid) disc with hydroxyapatite coating (measuring 4 mm diameter * 0.5 mm thickness). Treatment groups included dimethylsulfoxide control (n = 6), 0.5 mM SAG (n = 7) or 1.0 mM SAG (n = 7). Evaluation was performed at 4 and 8 weeks postoperative, by a combination of high-resolution microcomputed tomography, histology (H & E, Masson's Trichrome), histomorphometry, and immunohistochemistry (BSP, OCN, VEGF). In vivo results showed that SAG treatment induced a significant and dose-dependent increase in calvarial bone healing by all radiographic parameters. Histomorphometric analysis showed an increase in all parameters of bone formation with SAG treatment, but also an increase in blood vessel number and density. In summary, SAG is a pro-osteogenic, provasculogenic stimulus when applied locally in a bone defect environment. PMID- 27702398 TI - Mesenchymal Stem Cells and Pericytes: To What Extent Are They Related? AB - Mesenchymal stem cells (MSCs) were initially identified as progenitors of skeletal tissues within mammalian bone marrow and cells with similar properties were also obtained from other tissues such as adipose and dental pulp. Although MSCs have been extensively investigated, their native behavior and in vivo identity remain poorly defined. Uncovering the in vivo identity of MSCs has been challenging due to the lack of exclusive cell markers, cellular alterations caused by culture methods, and extensive focus on in vitro properties for characterization. Although MSC site of origin influences their functional properties, these mesenchymal progenitors can be found in the perivascular space in virtually all organs from where they were obtained. However, the precise identity of MSCs within the vascular wall is highly controversial. The recurrent concept that MSCs correspond to pericytes in vivo has been supported mainly by their perivascular localization and expression of some molecular markers. However, this view has been a subject of controversy, in part, due to the application of loose criteria to define pericytes and due to the lack of a marker able to unequivocally identify these cells. Furthermore, recent evidences indicate that subpopulations of MSCs can be found at extravascular sites such as the endosteum. In this opinion review, we bring together the advances and pitfalls on the search for the in vivo identity of MSCs and highlight the recent evidences that suggest that perivascular MSCs are adventitial cells, acting as precursors of pericytes and other stromal cells during tissue homeostasis. PMID- 27702399 TI - Negative work perception not changed in a short work-anxiety-coping group therapy intervention. AB - BACKGROUND: Work anxiety is often associated with long-term sick leave and requires early intervention. Work anxieties are associated with negative work perception. Therefore, one aim in early intervention is a cognitive reframing of dysfunctional perceptions of workplace characteristics. METHODS: A psychotherapeutic specialist conducted two group programs of four sessions each. One hundred twenty-three rehabilitation in-patients with work anxieties were randomly assigned either to a work anxiety-coping group or to a recreational group. The Short Questionnaire for Work Analysis (KFZA) was administered before and after the group treatment to measure perceptions of working conditions. RESULTS: Participants from the work anxiety-coping group did not see their work in a significantly more positive light at the end of the intervention compared to participants from the recreational group. CONCLUSIONS: A short work anxiety coping group did not initiate a consistent positive re-appraisal of work. Employers and occupational physicians should not expect positive changes of work perception when an employee returns from short medical rehabilitation including work-directed treatment. Additional support from the workplace must be considered, e.g. employer-physician-employee conversation preceding return to work, or (temporary) work adjustment. PMID- 27702400 TI - Association of aplastic anemia and FoxP3 gene polymorphisms in Koreans. AB - OBJECTIVES: Aplastic anemia (AA) is characterized by pancytopenia and bone marrow failure, and most acquired AA is an immune-mediated disorder. Regulatory T cells (Tregs) suppressing autoreactive T cells were decreased in AA patients. FoxP3 is a major regulator for the development and function of Tregs. Polymorphism in FoxP3 was shown to be associated with various autoimmune diseases, however, has not yet been studied in AA. In this study, we examined the association between FoxP3 polymorphisms and AA in Korean patients. METHODS: The study population consisted of 94 patients diagnosed by bone marrow examination in Seoul National University Hospital (SNUH) during 1997-2012 and 195 healthy controls. FoxP3 polymorphisms (rs5902434 del/ATT, rs3761548 C/A, rs3761549 C/T, rs2232365 A/G) were analyzed by PCR-sequencing method. We analyzed differences of genotype and allele frequencies between patients and controls. We also compared differences of genotype and allele frequencies between responder and non-responder in patients treated with immunosuppressive therapy (IST). For the statistical analysis, the chi-square test and Fisher's exact test were used and P < 0.05 was regarded as statistically significant. RESULTS: There was no significant difference in the genotype frequencies of FoxP3 polymorphisms between patients and controls. With regards to the allele frequencies, rs3761548 C allele was significantly higher in AA patients than in controls (87.4% vs. 79.7%, P = 0.047). In patients treated with IST, rs3761549 C allele was significantly higher in non-responder patients than in responders (89.6% vs. 66.7%, P = 0.036) and female rs3761549 C/C genotype carriers were associated with greater risk for non-response to IST (84.2% vs. 16.7%, P = 0.006). CONCLUSION: Polymorphisms in rs3761548 and rs3761549 of FoxP3 in our population were associated with disease susceptibility and response for IST, respectively. This study suggests an association between FoxP3 polymorphisms and AA in Korean patients and will be useful in further understanding the genetic basis of disease susceptibility and response to IST in AA patients. PMID- 27702401 TI - Evaluation of the orthodontic component of the hypodontia care pathway. AB - INTRODUCTION: This study evaluated patients' experiences of the Hypodontia Care Pathway at a large teaching hospital at key stages: specifically patient expectations/experience following the diagnosis of hypodontia and then patient satisfaction with the orthodontic care received and the outcome at the end of active orthodontic treatment. METHODOLOGY: In-depth, semi-structured interviews were conducted with 20 hypodontia patients following completion of orthodontic treatment but prior to any planned prosthodontic treatment commencing. Interviews were analysed qualitatively, using a framework approach. RESULTS: The framework analysis identified four main themes: perceptions of treatment, impact of the original malocclusion and the treatment process, the care team and communication. The themes were then further divided into subthemes. DISCUSSION: There was a large amount of positive feedback and the importance of the patient-clinician relationship was evident throughout. Where issues of concern were identified, these related mainly to communication and areas were identified where change could take place in the future. CONCLUSIONS: Positive feedback was received and the importance of patient-clinician rapport was highlighted in all interviews. The main areas that could be enhanced related to the importance of ensuring optimum communication, particularly with a cohort of patients who are often undergoing complex multidisciplinary treatment. Recommendations for the service have been made. PMID- 27702402 TI - Development of Antithrombotic Aptamers: From Recognizing Elements to Drugs. AB - Blood hemostasis is attained with two sophisticated interconnected network systems, a coagulation cascade and a platelet activation system. Multiple inhibitors were developed to various components of both systems to prevent thrombosis-related morbid events that are of extremely high frequency in the human population. Antithrombotic inhibitors possess both positive and negative aspects. One of the essential modern requirements is a controllable mode of action for both anticoagulants and antiplatelets that could be achieved due to the high affinity and specificity of the inhibitor, as well as a possibility to apply an antidote, which quickly annihilates activity of the inhibitor and restores the proper hemostasis. Aptamers are DNA or RNA oligonucleotides with particular tertiary structure, such as DNA guanine quadruplex. Besides antibodies and other peptides/proteins, aptamers are one more example of the molecular recognizing elements that specifically bind to the target. Therefore, aptamers could be developed into a promising novel class of the drugs with high affinity, specificity, innate low toxicity, and rational antidote. Several aptamers with prospective antithrombotic activity have been reviewed; some of them are in preclinical and clinical trials.

AB - Before the introduction of the Dutch Human Fertilisation (Donor Information) Act (in Dutch: Wet Donorgegevens Kunstmatige Bevruchting) in 2004, approximately 40,000 donor-conceived offspring were born in the Netherlands. The majority is conceived by means of artificial insemination with anonymous donor sperm (in Dutch: kunstmatige inseminatie met anoniem donorzaad - KID). This means that they have little or no access to information about their genetic origins. Through the Fiom KID-DNA Databank, established in 2010 in association with the Canisius Wilhelmina Hospital, it is possible for these donor-conceived offspring and donors to search for one another. DNA profiles are used to match donor-conceived offspring, donors and half-siblings. It is expected that the number of donor related searches will increase. The experiences with matching and counselling of donor-conceived offspring and donors presented in this paper will help donor conceived offspring and donors who start a search in the future. Moreover, they provide guidance for forming a meaningful relationship between those involved. PMID- 27702404 TI - [Fibrous dysplasia: a heterogeneous disease]. AB - Fibrous dysplasia is a rare genetic bone disorder with a wide variation in clinical expression, ranging from asymptomatic patients to severely affected patients with extensive bone disease, pain, repetitive fractures and deformities and serious endocrinological symptoms (McCune-Albright syndrome). Here, we report on three different cases of fibrous dysplasia. First, a 46-year-old woman with a small solitary lesion in the proximal femur. Second, a 25-year-old man with polyostotic disease of the left leg who received both surgical and medical treatment. Third, a 7-year-old girl with McCune-Albright syndrome who was diagnosed with precocious puberty as a baby and who had extensive disease throughout the skeleton, including multiple lesions in the craniofacial region. The aetiology, clinical expression, diagnostic work-up and therapeutic options for fibrous dysplasia are discussed in a short resume of the disease. PMID- 27702405 TI - [Can apps encourage a healthier and more active lifestyle?] AB - OBJECTIVE: To present an overview of the literature on the effect of smartphone apps and activity trackers on a healthy lifestyle. DESIGN: Systematic review. METHOD: PubMed, the Cochrane Library, Embase and CINAHL were searched for relevant articles. Inclusion criteria were: (a) the intervention was a mobile app or activity tracker; (b) that stimulated activity and healthy diet; (c) in adults with an unhealthy lifestyle but so far without medical disorders; (d) aimed at preventative healthcare, improvement in health or healthy behaviour; and (e) measured the effect of physical activity, diet and weight. RESULTS: We included 17 studies, of which 13 involved apps and 4 involved activity trackers. The effect of the apps on physical activity in overweight or obese people was positive in 6 studies, while no effect was found in 3 studies. There was a positive effect on diet; this was significant in 3 studies and non-significant in 2 studies. The effect on weight was positive in 6 studies, while no effect was found in 5 studies. Evidential value of the studies involving apps was poor to moderate. Activity trackers seemed to have the power to increase physical activity, but quality of these studies was poor. The effects on weight were contradictory and the effects on diet were not investigated. CONCLUSION: Apps have a global positive effect on physical activity. The effect of apps on diet and weight is unclear, but the trend is that they improve eating patterns. Activity trackers can increase physical activity. Larger scale research with more balanced control groups and longer follow-up is, however, necessary before we can recommend the use of apps and activity trackers. PMID- 27702407 TI - [Diagnostics and treatment of lower extremity peripheral arterial disease; guideline and registry]. AB - - Revision of the 2005 guideline 'Diagnostics and treatment of lower extremity peripheral arterial disease' and the development of an audit have instigated a degree of efficiency and transparency for the treatment of patients with peripheral arterial disease (PAD). - The key recommendations are that first-line treatment of patients, who - preferably by means of a consultation in a vascular laboratory - are diagnosed with intermittent claudication, is supervised exercise therapy and secondary prevention. Referral for second-line treatment only needs to occur when invasive therapy is considered, for example when there is insufficient improvement in symptoms or in patients who have or are developing critical ischemia. - In case of endovascular treatments it is not necessary to insert stents routinely; this can be reserved for cases where the angiographic result of the angioplasty is insufficient. - All patients with PAD are registered on the DAPA register ('Dutch audit for peripheral arterial disease'), which has two unique characteristics: patient reported outcome measures (PROMs) are recorded and a case mix correction is incorporated for the PROMs and amputation free survival through linkage with the health insurance database. PMID- 27702406 TI - [Is a salt-restricted diet now up for discussion?] AB - A recent meta-analysis published in The Lancet related sodium excretion to mortality in both hypertensive and normotensive subjects. High salt excretion, measured in a spot urine test, was related to increased mortality in hypertensive subjects only, whereas low sodium excretion was related to increased mortality in both hypertensive and normotensive subjects. Here we discuss practical consequences of this analysis. The data underline the importance of salt restriction in hypertension; the analysis also shows that there is a lower limit to salt restriction. Since salt intake cannot be assessed adequately from the sodium content of a single urine sample, 24-hour urine collection is advised in subjects on a salt-restricted diet. A 24-hour urine collection allows checking for unnecessarily strict salt restriction or, as will more often be the case, shows the patient that adequate salt restriction has not yet been attained. PMID- 27702408 TI - [Effectiveness of lifestyle apps not yet proven]. AB - In a systematic review in the Dutch Journal of Medicine (NTvG), Dallinga et al. look for an answer to the societally relevant question of whether mobile apps are proven to lead to a more active and healthy lifestyle. Decision makers in healthcare have high expectations of eHealth, a field where scientific evidence sometimes seems overruled merely by the opinions of self-declared 'futurists'. Commonly, eHealth is propelled forward as the solution to the lack of manpower in healthcare, given the expected rise of chronic disease. However, an earlier analysis of 108 systematic reviews on the impact of eHealth technologies shows that a plethora of claims are not supported by sound evidence. It is therefore worthwhile to assess the current evidence for the effectiveness of health apps on exercise and healthy nutrition. PMID- 27702410 TI - Decontamination in the Electron Probe Microanalysis with a Peltier-Cooled Cold Finger. AB - A prototype Peltier thermoelectric cooling unit has been constructed to cool a cold finger on an electron microprobe. The Peltier unit was tested at 15 and 96 W, achieving cold finger temperatures of -10 and -27 degrees C, respectively. The Peltier unit did not adversely affect the analytical stability of the instrument. Heat conduction between the Peltier unit mounted outside the vacuum and the cold finger was found to be very efficient. Under Peltier cooling, the vacuum improvement associated with water vapor deposition was not achieved; this has the advantage of avoiding severe degradation of the vacuum observed when warming up a cold finger from liquid nitrogen (LN2) temperatures. Carbon contamination rates were reduced as cooling commenced; by -27 degrees C contamination rates were found to be comparable with LN2-cooled devices. Peltier cooling, therefore, provides a viable alternative to LN2-cooled cold fingers, with few of their associated disadvantages. PMID- 27702409 TI - The relationship between micronutrient status and sleep patterns: a systematic review. AB - OBJECTIVE: To review articles on the relationship of dietary and circulating micronutrients with sleep patterns, and to identify issues surrounding implications for future research and public health practice. DESIGN: A systematic review was conducted. PubMed, Embase and Scopus were searched through January 2016. SETTING: Both experimental and observational studies were included. However, studies that focused on secondary sleep impairment due to comorbidities were excluded. SUBJECTS: Individuals in different age groups, from infants to older adults. RESULTS: A total of twenty-six articles were selected. In the articles reviewed, researchers generally supported a potential role of micronutrients, particularly Fe and Mg, in the development of sleep stages among infants and in reversing age-related alterations in sleep architecture in older adults. Micronutrient status has also been linked to sleep duration, with sleep duration positively associated with Fe, Zn and Mg levels, and negatively associated with Cu, K and vitamin B12 levels. The mechanisms underlying these relationships include the impact of micronutrients on excitatory/inhibitory neurotransmitters and the expression of circadian genes. CONCLUSIONS: Although the number of studies on the relationship between micronutrient status and sleep remains low, evidence has emerged that suggests a link between dietary/circulating micronutrients and sleep. Future research is needed to investigate the dose-dependent as well as the longitudinal relationships between micronutrient levels and human sleep across populations, test the interactions among micronutrients on sleep outcomes, and ultimately examine the clinical relevance of micronutrients on sleep health. PMID- 27702411 TI - Effect of agomelatine treatment on C-reactive protein levels in patients with major depressive disorder: an exploratory study in "real-world," everyday clinical practice. AB - OBJECTIVE: Agomelatine is a newer antidepressant but, to date, no studies have been carried out investigating its effects on C-reactive protein (CRP) levels in major depressive disorder (MDD) before and after treatment. The present study aimed (i) to investigate the effects of agomelatine treatment on CRP levels in a sample of patients with MDD and (ii) to investigate if CRP variations were correlated with clinical improvement in such patients. METHODS: 30 adult outpatients (12 males, 18 females) with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) diagnosis of MDD were recruited in "real-world," everyday clinical practice and treated with a flexible dose of agomelatine for 12 weeks. The Hamilton Rating Scale for Depression (HAM D) and the Snaith-Hamilton Pleasure Scale (SHAPS) were used to evaluate depressive symptoms and anhedonia, respectively. Moreover, serum CRP was measured at baseline and after 12 weeks of treatment. RESULTS: Agomelatine was effective in the treatment of MDD, with a significant reduction in HAM-D and SHAPS scores from baseline to endpoint. CRP levels were reduced in the whole sample, with remitters showing a significant difference in CRP levels after 12 weeks of agomelatine. A multivariate stepwise linear regression analysis showed that higher CRP level variation was associated with higher baseline HAM-D scores, controlling for age, gender, smoking, BMI, and agomelatine dose. CONCLUSIONS: Agomelatine's antidepressant properties were associated with a reduction in circulating CRP levels in MDD patients who achieved remission after 12 weeks of treatment. Moreover, more prominent CRP level variation was associated with more severe depressive symptoms at baseline. PMID- 27702412 TI - Where do food desert residents buy most of their junk food? Supermarkets. AB - OBJECTIVE: To examine where residents in an area with limited access to healthy foods (an urban food desert) purchased healthier and less healthy foods. DESIGN: Food shopping receipts were collected over a one-week period in 2013. These were analysed to describe where residents shopped for food and what types of food they bought. SETTING: Two low-income, predominantly African-American neighbourhoods with limited access to healthy foods in Pittsburgh, PA, USA. SUBJECTS: Two hundred and ninety-three households in which the primary food shoppers were predominantly female (77.8 %) and non-Hispanic black (91.1 %) adults. RESULTS: Full-service supermarkets were by far the most common food retail outlet from which food receipts were returned and accounted for a much larger proportion (57.4 %) of food and beverage expenditures, both healthy and unhealthy, than other food retail outlets. Although patronized less frequently, convenience stores were notable purveyors of unhealthy foods. CONCLUSIONS: Findings highlight the need to implement policies that can help to decrease unhealthy food purchases in full-service supermarkets and convenience stores and increase healthy food purchases in convenience stores.

PMID- 27702414 TI - Validity of LIDAS (LIfetime Depression Assessment Self-report): a self-report online assessment of lifetime major depressive disorder. AB - BACKGROUND: There is a paucity of valid, brief instruments for the assessment of lifetime major depressive disorder (MDD) that can be used in, for example, large scale genomics, imaging or biomarker studies on depression. We developed the LIfetime Depression Assessment Self-report (LIDAS), which assesses lifetime MDD diagnosis according to DSM criteria, and is largely based on the widely used Composite International Diagnostic Interview (CIDI). Here, we tested the feasibility and determined the sensitivity and specificity for measuring lifetime MDD with this new questionnaire, with a regular CIDI as reference. METHOD: Sensitivity and specificity analyses of the online lifetime MDD questionnaire were performed in adults with (n = 177) and without (n = 87) lifetime MDD according to regular index CIDIs, selected from the Netherlands Study of Depression and Anxiety (NESDA) and Netherlands Twin Register (NTR). Feasibility was tested in an additional non-selective, population-based sample of NTR participants (n = 245). RESULTS: Of the 753 invited persons, 509 (68%) completed the LIDAS, of which 419 (82%) did this online. User-friendliness of the instrument was rated high. Median completion time was 6.2 min. Sensitivity and specificity for lifetime MDD were 85% [95% confidence interval (CI) 80-91%] and 80% (95% CI 72-89%), respectively. This LIDAS instrument gave a lifetime MDD prevalence of 20.8% in the population-based sample. CONCLUSIONS: Measuring lifetime MDD with an online instrument was feasible. Sensitivity and specificity were adequate. The instrument gave a prevalence of lifetime MDD in line with reported population prevalences. LIDAS is a promising tool for rapid determination of lifetime MDD status in large samples, such as needed for genomics studies. PMID- 27702415 TI - Shared Genetic Factors in the Co-Occurrence of Depression and Fatigue. AB - Depression and fatigue have previously been suggested to share an underlying genetic contribution. The present study aims to investigate and characterize the familiality and genetic relationship between depression and fatigue. The familiality of depression and fatigue was assessed by calculating relative risks, measured by the prevalence ratio, within 643 monozygotic (MZ) and 577 dizygotic (DZ) twin pairs. Bivariate twin modeling was utilized to assess the magnitude of shared heritability between depression and fatigue. Finally, the relationship between depression and fatigue was investigated using the co-twin control method, to determine whether the association is explained by causal or non-causal models. We observed an increased risk of fatigue in co-twins of probands with depression and increased risk of depression in co-twins of probands with fatigue. Higher risks were observed in MZ compared to DZ twin pairs, and bivariate heritability analyses indicated significant genetic components for depression and fatigue, with heritability estimates of 48% and 41%, respectively. Importantly, a significant additive genetic correlation of 0.71 [95% CI = 0.51-0.92) and bivariate heritability of 21% [95% CI = 10-35%] was observed between depression and fatigue. Furthermore, results from the co-twin control method indicate a non causal genetic relationship that likely explains the association between depression and fatigue. Notably, the contribution of shared genetic factors remained significant, independent of the overlapping symptoms, indicating that the relationship between co-occurring depression and fatigue is primarily due to shared genetic factors rather than overlapping symptomatology. PMID- 27702416 TI - Coil occlusion of aberrant arteries to pulmonary sequestration in a case with pulmonary atresia with intact ventricular septum: successful treatment of repetitive myocardial ischaemic attacks. AB - In this study, we describe an infant case of pulmonary atresia with intact ventricular septum associated with ventriculo-coronary arterial communication for which a modified Blalock-Taussig shunt operation was performed. He experienced repeated myocardial ischaemic attacks. Further examination revealed pulmonary sequestration in the right lower lobe. He therefore underwent a bidirectional Glenn operation and coil occlusion of the feeding arteries. His myocardial ischaemic attacks subsequently improved. PMID- 27702417 TI - Differences in expenditure and amounts of fresh foods, fruits and vegetables, and fish purchased in urban and rural Scotland. AB - OBJECTIVE: To quantitatively analyse expenditure on all fresh foods, fruits and vegetables (F&V) and fish across urban and rural households in Scotland. Fresh foods were chosen since, in general, they are perceived to contribute more to health than processed foods. DESIGN: Descriptive analysis of purchase data of all foods brought into the home during 2012 from the Kantar Worldpanel database. Purchase data were restricted to fresh, unprocessed and raw foods or 'fresh to frozen' foods where freezing was part of harvesting. Total household purchases were adjusted for household size and composition. SETTING: Scotland. SUBJECTS: Households (n 2576). RESULTS: Rural households reported the highest expenditure per person on fresh foods and F&V, but also bought the most (kilograms) of these items. There were linear trends of average prices paid with urban-rural location (P<0.001), with average prices paid by large urban and remote rural households being L2.14/kg and L2.04/kg for fresh foods, L1.64/kg and L1.60/kg for F&V and L10.07/kg and L10.20/kg for fish, respectively, although differences were quantitatively small. CONCLUSIONS: Contrary to previous studies, purchase data show that access to and average prices of fresh foods generally, and F&V and fish specifically, are broadly similar between urban and rural areas. Therefore, the higher expenditure on these foods in rural v. urban areas is probably due to factors other than pricing and availability. PMID- 27702418 TI - Density mediates grasshopper performance in response to temperature manipulation and spider predation in tallgrass prairie. AB - Species interactions are often context-dependent, where outcomes require an understanding of influences among multiple biotic and abiotic factors. However, it remains unclear how abiotic factors such as temperature combine with important biotic factors such as density-dependent food limitation and predation to influence species interactions. Using a native grassland - grasshopper - wolf spider model food chain in tallgrass prairie, we conducted a manipulative field experiment to examine how predator-prey interactions respond to manipulations of temperature, grasshopper density, and food chain length. We find that grasshopper performance responses to temperature and predator treatments were density dependent. At high densities, grasshopper survival decreased with increased temperature when no spiders were present. When spiders were present, grasshopper survival was reduced, and this effect was strongest in the cooled treatment. In contrast, grasshopper survival did not vary significantly with spider presence or among temperature treatments at low grasshopper densities. Our results indicate that context-dependent species interactions are common and highlight the importance of understanding how and when key biotic and abiotic factors combine to influence species interactions. PMID- 27702419 TI - Expression of the T85A mutant of zebrafish aquaporin 3b improves post-thaw survival of cryopreserved early mammalian embryos. AB - While vitrification has become the method of choice for preservation of human oocytes and embryos, cryopreservation of complex tissues and of large yolk containing cells, remains largely unsuccessful. One critical step in such instances is appropriate permeation while avoiding potentially toxic concentrations of cryoprotectants. Permeation of water and small non-charged solutes, such as those used as cryoprotectants, occurs largely through membrane channel proteins termed aquaporins (AQPs). Substitution of a Thr by an Ala residue in the pore-forming motif of the zebrafish (Dario rerio) Aqp3b paralog resulted in a mutant (DrAqp3b-T85A) that when expressed in Xenopus or porcine oocytes increased their permeability to ethylene glycol at pH 7.5 and 8.5. The main objective of this study was to test whether ectopic expression of DrAqp3b T85A also conferred higher resistance to cryoinjury. For this, DrAqp3b-T85A + eGFP (reporter) cRNA, or eGFP cRNA alone, was microinjected into in vivo fertilized 1-cell mouse zygotes. Following culture to the 2-cell stage, appropriate membrane expression of DrAqp3b-T85A was confirmed by immunofluorescence microscopy using a primary specific antibody directed against the C-terminus of DrAqp3b. Microinjected 2-cell embryos were then cryopreserved using a fast-freezing rate and low concentration (1.5 M) of ethylene glycol in order to highlight any benefits from DrAqp3b-T85A expression. Notably, post-thaw survival rates were higher (P<0.05) for T85A-eGFP-injected than for -uninjected or eGFP-injected embryos (73+/-7.3 vs. 28+/-7.3 or 14+/-6.7, respectively). We propose that ectopic expression of mutant AQPs may provide an avenue to improve cryopreservation results of large cells and tissues in which current vitrification protocols yield low survival. PMID- 27702420 TI - Clinical management of restless legs syndrome in end-stage renal disease patients. AB - Restless legs syndrome (RLS) is a common neurological movement disorder, characterized by restless and unpleasant sensations in the deep inside of legs. The symptoms of RLS are less noticeable during daytime, but more prevalent at night. Therefore, the disorder can induce low quality of life, insomnia, and impairment of daytime activity. RLS in end-stage renal disease (ESRD) patients is especially problematic due to premature discontinuation of dialysis and increased mortality. The prevalence of RLS among dialysis patients is much higher compared to the prevalence of the same disorder in patients with normal renal functions. Even though there are recommended treatment guidelines for the general population established by Medical Advisory Board of the RLS foundation, which include the use of dopamine agonists, levodopa, gabapentin, benzodiazepines, and opioids, limited information is available on the effects of these therapies in ESRD patients. Since the existing clinical data were extrapolated from small sample sizes in short-term clinical trials, further clinical studies are still needed to better assess the efficacy, safety, and tolerability of these medications in patients with ESRD. PMID- 27702421 TI - Non-farmed fish contribute to greater micronutrient intakes than farmed fish: results from an intra-household survey in rural Bangladesh. AB - OBJECTIVE: Fish is the most important animal-source food (ASF) in Bangladesh, produced from capture fisheries (non-farmed) and aquaculture (farmed) sub sectors. Large differences in micronutrient content of fish species from these sub-sectors exist. The importance of fish in diets of vulnerable groups compared with other ASF; contribution from non-farmed and farmed species to nutrient intakes; and differences in fish consumption among age, gender, wealth groups and geographic regions were analysed, using quantitative intra-household fish consumption data, focusing on the first 1000 d of life. DESIGN: Two-stage stratified sample. SETTING: Nationally representative of rural Bangladesh. SUBJECTS: Households (n 5503) and individuals (n 24 198). RESULTS: Fish consumption in poor households was almost half that in wealthiest households; and lower in females than males in all groups, except the wealthiest, and for those aged >=15 years (P<0.01). In infants of complementary feeding age, 56 % did not consume ASF on the survey day, despite 78 % of mothers knowing this was recommended. Non-farmed fish made a larger contribution to Fe, Zn, Ca, vitamin A and vitamin B12 intakes than farmed fish (P<0.0001). CONCLUSIONS: Policies and programmes aimed to increase fish consumption as a means to improve nutrition in rural Bangladesh should focus on women and young children, and on the poorest households. Aquaculture plays an important role in increasing availability and affordability of fish; however, non-farmed fish species are better placed to contribute to greater micronutrient intakes. This presents an opportunity for aquaculture to contribute to improved nutrition, utilising diverse production technologies and fish species, including small fish. PMID- 27702423 TI - SOCE proteins, STIM1 and Orai1, are localized to the cleavage furrow during cytokinesis of the first and second cell division cycles in zebrafish embryos. AB - In zebrafish embryos, distinct Ca2+ transients are localized to the early cleavage furrows during the first few cell division cycles. These transients are generated mainly by release via IP3Rs in the endoplasmic reticulum, and they are necessary for furrow positioning, propagation, deepening and apposition. We previously showed, via the use of inhibitors, that store-operated Ca2+ entry (SOCE) also appears to be essential for maintaining the IP3R-mediated elevated levels of [Ca2+]i for the extended periods required for the completion of successful furrow deepening and daughter cell apposition in these large embryonic cells. Here, newly fertilized, dechorionated embryos were fixed at various times during the first and second cell division cycles and immunolabelled with antibodies to STIM1 and/or Orai1 (key components of SOCE). We show that both of these proteins have a dynamic pattern of localization during cytokinesis of the first two cell division cycles. These new data help to support our previous inhibitor results, and provide additional evidence that SOCE contributes to the maintenance of the sustained elevated Ca2+ that is required for the successful completion of cytokinesis in the large cells of embryonic zebrafish. PMID- 27702422 TI - Parental supply of alcohol and alcohol consumption in adolescence: prospective cohort study. AB - BACKGROUND: Parents are a major supplier of alcohol to adolescents, yet there is limited research examining the impact of this on adolescent alcohol use. This study investigates associations between parental supply of alcohol, supply from other sources, and adolescent drinking, adjusting for child, parent, family and peer variables. METHOD: A cohort of 1927 adolescents was surveyed annually from 2010 to 2014. Measures include: consumption of whole drinks; binge drinking (>4 standard drinks on any occasion); parental supply of alcohol; supply from other sources; child, parent, family and peer covariates. RESULTS: After adjustment, adolescents supplied alcohol by parents had higher odds of drinking whole beverages [odds ratio (OR) 1.80, 95% confidence interval (CI) 1.33-2.45] than those not supplied by parents. However, parental supply was not associated with bingeing, and those supplied alcohol by parents typically consumed fewer drinks per occasion (incidence rate ratio 0.86, 95% CI 0.77-0.96) than adolescents supplied only from other sources. Adolescents obtaining alcohol from non-parental sources had increased odds of drinking whole beverages (OR 2.53, 95% CI 1.86 3.45) and bingeing (OR 3.51, 95% CI 2.53-4.87). CONCLUSIONS: Parental supply of alcohol to adolescents was associated with increased risk of drinking, but not bingeing. These parentally-supplied children also consumed fewer drinks on a typical drinking occasion. Adolescents supplied alcohol from non-parental sources had greater odds of drinking and bingeing. Further follow-up is necessary to determine whether these patterns continue, and to examine alcohol-related harm trajectories. Parents should be advised that supply of alcohol may increase children's drinking. PMID- 27702424 TI - Duration of periconceptional folic acid supplementation in women booking for antenatal care. AB - OBJECTIVE: To provide accurate estimates of the commencement time, duration and dosage of folic acid (FA) supplementation taken by Irish women in the periconceptional period. The study also aimed to establish the factors associated with optimal FA supplementation practices. DESIGN: Cross-sectional observational study. Women's clinical and sociodemographic details were computerised. Maternal weight and height were measured before calculating BMI. Detailed FA supplementation questionnaires were completed under the supervision of a trained researcher. SETTING: A large university maternity hospital, Republic of Ireland, January 2014-April 2016. SUBJECTS: Women (n 856) recruited at their convenience in the first trimester. RESULTS: While almost all of the women (97 %) were taking FA at enrolment, only one in four women took FA for at least 12 weeks preconceptionally (n 208). Among the 44 % of women who were supplementing with FA preconceptionally, 44 % (162/370) reported taking FA for less than the 12 weeks required to achieve optimal red-blood-cell folate levels for prevention of neural tube defects. On multivariate analysis, only planned pregnancy and nulliparity were associated with taking FA for at least 12 weeks preconceptionally. Among women who only took FA postconceptionally, almost two-thirds commenced it after day 28 of their pregnancy when the neural tube had already closed. CONCLUSIONS: As the timing of FA was suboptimal both before and after conception, we recommend that current national FA guidelines need to be reviewed. PMID- 27702425 TI - Nutrition education linked to agricultural interventions improved child dietary diversity in rural Cambodia. AB - Poor infant and young child feeding (IYCF) practices are major determinants of chronic malnutrition. The main objective of this study was to assess the impact of a nutrition education (NE) programme aimed at promoting improved IYCF behaviours in combination with an agriculture intervention on children's dietary diversity and nutritional status. From 2012 to 2014, a cluster randomised trial was rolled out in Cambodia in the context of an agriculture and nutrition project of the FAO of the UN. The cross-sectional baseline study was carried out in sixteen pre-selected communes in 2012. Restricted randomisation allotted the communes to either intervention (NE and agriculture intervention) or comparison arms (agriculture intervention only). The impact survey was conducted as a census in all FAO project villages in 2014. Caregivers of children aged 0-23 months were interviewed using standardised questions on socio-economic status and dietary diversity (24-h recall). Anthropometric measurements were taken. A difference-in differences model was applied. The sample comprised 743 households with children >=6 months of age at baseline and 921 at impact. After 1 year of NE, 69 % of the intervention households reported to have participated in the NE. Estimated mean child dietary diversity was significantly different at impact between comparison and intervention (3.6 and 3.9, respectively). In particular, the consumption of pro-vitamin A-rich foods and other fruits and vegetables increased. No treatment effects on height-for-age Z-scores could be shown. NE led to improvements in children's diets. For effects on growth, it is assumed that longer NE activities are required to achieve sustainable behaviour change of age-appropriate infant feeding. PMID- 27702426 TI - Burkholderia pseudomallei resistance to antibiotics in biofilm-induced conditions is related to efflux pumps. AB - Burkholderia pseudomallei, the causative agent of melioidosis, has been found to increase its resistance to antibiotics when growing as a biofilm. The resistance is related to several mechanisms. One of the possible mechanisms is the efflux pump. Using bioinformatics analysis, it was found that BPSL1661, BPSL1664 and BPSL1665 were orthologous genes of the efflux transporter encoding genes for biofilm-related antibiotic resistance, PA1874-PA1877 genes in Pseudomonas aeruginosa strain PAO1. Expression of selected encoding genes for the efflux transporter system during biofilm formation were investigated. Real-time reverse transcriptase PCR expression of amrB, cytoplasmic membrane protein of AmrAB-OprA efflux transporter encoding gene, was slightly increased, while BPSL1665 was significantly increased during growth of bacteria in biofilm formation. Minimum biofilm inhibition concentration and minimum biofilm eradication concentration (MBEC) of ceftazidime (CTZ), doxycycline (DOX) and imipenem were found to be 2- to 1024-times increased when compared to their MICs for of planktonic cells. Inhibition of the efflux transporter by adding phenylalanine arginine beta napthylamide (PAbetaN), a universal efflux inhibitor, decreased 2 to 16 times as much as MBEC in B. pseudomallei biofilms with CTZ and DOX. When the intracellular accumulation of antibiotics was tested to reveal the pump inhibition, only the concentrations of CTZ and DOX increased in PAbetaN treated biofilm. Taken together, these results indicated that BPSL1665, a putative precursor of the efflux pump gene, might be related to the adaptation of B. pseudomallei in biofilm conditions. Inhibition of efflux pumps may lead to a decrease of resistance to CTZ and DOX in biofilm cells. PMID- 27702427 TI - Presence of Cx43 in extracellular vesicles reduces the cardiotoxicity of the anti tumour therapeutic approach with doxorubicin. AB - Extracellular vesicles (EVs) are major conveyors of biological information, mediating local and systemic cell-to-cell communication under physiological and pathological conditions. These endogenous vesicles have been recognized as prominent drug delivery vehicles of several therapeutic cargoes, including doxorubicin (dox), presenting major advantages over the classical approaches. Although dox is one of the most effective anti-tumour agents in the clinical practice, its use is very often hindered by its consequent dramatic cardiotoxicity. Despite significant advances witnessed in the past few years, more comprehensive studies, supporting the therapeutic efficacy of EVs, with decreased side effects, are still scarce. The main objective of this study was to evaluate the role of the gap junction protein connexin43 (Cx43) in mediating the release of EV content into tumour cells. Moreover, we investigated whether Cx43 improves the efficiency of dox-based anti-tumour treatment, with a concomitant decrease of cardiotoxicity. In the present report, we demonstrate that the presence of Cx43 in EVs increases the release of luciferin from EVs into tumour cells in vitro and in vivo. In addition, using cell-based approaches and a subcutaneous mouse tumour model, we show that the anti-tumour effect of dox incorporated into EVs is similar to the administration of the free drug, regardless the presence of Cx43. Strikingly, we demonstrate that the presence of Cx43 in dox-loaded EVs reduces the cardiotoxicity of the drug. Altogether, these results bring new insights into the concrete potential of EVs as therapeutic vehicles and open new avenues toward the development of strategies that help to reduce unwanted side effects. PMID- 27702428 TI - Food sources of energy and nutrients in Finnish girls and boys 6-8 years of age - the PANIC study. AB - BACKGROUND: Data on food sources of nutrients are needed to improve strategies to enhance nutrient intake among girls and boys in Western countries. OBJECTIVE: To identify major food sources of energy, energy nutrients, dietary fibre, and micronutrients, and to study gender differences in these food sources among children. DESIGN: We assessed food consumption and nutrient intake using 4-day food records in a population sample of Finnish girls (n=213) and boys (n=217) aged 6-8 years from the Physical Activity and Nutrition in Children Study. We calculated the percentual contribution of 55 food groups for energy and nutrient intake using the population proportion method. RESULTS: Low-fibre grain products, skimmed milk, and high-fibre bread provided almost 23% of total energy intake. Skimmed milk was the top source of protein (18% of total intake), vitamin D (32%), potassium (20%), calcium (39%), magnesium (17%), and zinc (16%). Vegetable oils (15%) and high-fat vegetable oil-based spreads (14%) were the top sources of polyunsaturated fat. High-fibre bread was the top source of fibre (27%) and iron (12%). Non-root vegetables were the top source of folate (14%) and vitamin C (22%). Sugar-sweetened beverages provided 21% of sucrose intake. Pork was a more important source of protein and sausage was a more important source of total fat and monounsaturated fat in boys than in girls. Vegetable oils provided a higher proportion of unsaturated fat and vitamin E among boys, whereas high-fat vegetable oil-based spreads provided a higher proportion of these nutrients among girls. CONCLUSION: Commonly recommended foods, such as skimmed milk, high-fibre grain products, vegetables, vegetable oil, and vegetable oil-based spreads, were important sources of several nutrients, whereas sugar-sweetened beverages provided the majority of sucrose intake among children. This knowledge can be used in improving health among children by dietary interventions, nutrition education, and health policy decision making. PMID- 27702429 TI - Conventional deep pressure algometry is not suitable for clinical assessment of nociception in painless diabetic neuropathy. AB - BACKGROUND: In diabetic persons with painless neuropathic foot ulceration, foot skin was found to be insensate to noxious pinprick stimulation (stimulation area less than 0.05 mm2), while compression of deep subcutaneous foot tissues by Algometer II(r) (stimulation area 1 cm2) could evoke a deep dull aching. To elucidate this discrepancy, the Algometer II stimulation technique was critically reviewed by varying probe sizes and anatomical sites in the same study population 3 years later. METHODS: Ten control subjects without neuropathy and 11 persons with painless diabetic neuropathy (PLDN, seven of whom with diabetic foot syndrome, i.e., past painless foot ulcer, or inactive Charcot arthropathy) were re-examined using Algometer II. Deep pressure pain perception threshold (DPPPT) was measured in random sequence with stimulation areas of 0.5 cm2, 1 cm2, and 2 cm2 (separated by 5 min intervals), at the plantar forefoot, the instep, and the hindfoot of both legs. RESULTS: In the control and PLDN groups, median DPPPTs differed significantly between stimulation areas (highest with 0.5 cm2, intermediate with 1 cm2, lowest with 2 cm2; p<0.001), and varied moderately by anatomical site. Between-group differences were relatively small. Results of the 1 cm2 assessments repeated 3 years apart were similar. CONCLUSIONS: Algometer II readings represent spatial summation of low-threshold pressure-receptor rather than of high-threshold nociceptor stimulation and are, thus, unhelpful for assessing PLDN. Reproducibility of the measurements is good. PMID- 27702430 TI - Prevention literacy: community-based advocacy for access and ownership of the HIV prevention toolkit. AB - INTRODUCTION: Critical technological advances have yielded a toolkit of HIV prevention strategies. This literature review sought to provide contextual and historical reflection needed to bridge the conceptual gap between clinical efficacy and community effectiveness (i.e. knowledge and usage) of existing HIV prevention options, especially in resource-poor settings. METHODS: Between January 2015 and October 2015, we reviewed scholarly and grey literatures to define treatment literacy and health literacy and assess the current need for literacy related to HIV prevention. The review included searches in electronic databases including MEDLINE, PsycINFO, PubMed, and Google Scholar. Permutations of the following search terms were used: "treatment literacy," "treatment education," "health literacy," and "prevention literacy." Through an iterative process of analyses and searches, titles and/or abstracts and reference lists of retrieved articles were reviewed for additional articles, and historical content analyses of grey literature and websites were additionally conducted. RESULTS AND DISCUSSION: Treatment literacy was a well-established concept developed in the global South, which was later partially adopted by international agencies such as the World Health Organization. Treatment literacy emerged as more effective antiretroviral therapies became available. Developed from popular pedagogy and grassroots efforts during an intense struggle for treatment access, treatment literacy addressed the need to extend access to underserved communities and low income settings that might otherwise be excluded from access. In contrast, prevention literacy is absent in the recent surge of new biomedical prevention strategies; prevention literacy was scarcely referenced and undertheorized in the available literature. Prevention efforts today include multimodal techniques, which jointly comprise a toolkit of biomedical, behavioural, and structural/environmental approaches. However, linkages to community advocacy and mobilization efforts are limited and unsustainable. Success of prevention efforts depends on equity of access, community-based ownership, and multilevel support structures to enable usage and sustainability. CONCLUSIONS: For existing HIV prevention efforts to be effective in "real-world" settings, with limited resources, reflection on historical lessons and contextual realities (i.e. policies, financial constraints, and biomedical patents) indicated the need to extend principles developed for treatment access and treatment literacy, to support prevention literacy and prevention access as an integral part of the global response to HIV. PMID- 27702431 TI - Do MCAT scores predict USMLE scores? An analysis on 5 years of medical student data. AB - INTRODUCTION: The purpose of this study was to determine the associations and predictive values of Medical College Admission Test (MCAT) component and composite scores prior to 2015 with U.S. Medical Licensure Exam (USMLE) Step 1 and Step 2 Clinical Knowledge (CK) scores, with a focus on whether students scoring low on the MCAT were particularly likely to continue to score low on the USMLE exams. METHOD: Multiple linear regression, correlation, and chi-square analyses were performed to determine the relationship between MCAT component and composite scores and USMLE Step 1 and Step 2 CK scores from five graduating classes (2011-2015) at the University of Minnesota Medical School (N=1,065). RESULTS: The multiple linear regression analyses were both significant (p<0.001). The three MCAT component scores together explained 17.7% of the variance in Step 1 scores (p<0.001) and 12.0% of the variance in Step 2 CK scores (p<0.001). In the chi-square analyses, significant, albeit weak associations were observed between almost all MCAT component scores and USMLE scores (Cramer's V ranged from 0.05 to 0.24). DISCUSSION: Each of the MCAT component scores was significantly associated with USMLE Step 1 and Step 2 CK scores, although the effect size was small. Being in the top or bottom scoring range of the MCAT exam was predictive of being in the top or bottom scoring range of the USMLE exams, although the strengths of the associations were weak to moderate. These results indicate that MCAT scores are predictive of student performance on the USMLE exams, but, given the small effect sizes, should be considered as part of the holistic view of the student. PMID- 27702432 TI - Mystery behind the match: an undergraduate medical education-graduate medical education collaborative approach to understanding match goals and outcomes. AB - BACKGROUND: There is a paucity of information regarding institutional targets for the number of undergraduate medical education (UME) graduates being matched to graduate medical education (GME) programs at their home institutions. At our institution, the Duke University, the number of UME graduates matched to GME programs declined dramatically in 2011. To better understand why this decline may have happened, we sought to identify perceived quality metrics for UME and GME learners, evaluate trends in match outcomes and educational program characteristics, and explore whether there is an ideal retention rate for UME graduates in their home institutions' GME programs. METHODS: We analyzed the number of Duke University UME graduates remaining at Duke for GME training over the past 5 years. We collected data to assess for changing characteristics of UME and GME, and performed descriptive analysis of trends over time to investigate the potential impact on match outcomes. RESULTS: A one-sample t-test analysis showed no statistically significant difference in the number of Duke UME graduates who stayed for GME training. For both UME and GME, no significant changes in the characteristics of either program were found. DISCUSSION: We created a process for monitoring data related to the characteristics or perceived quality of UME and GME programs and developed a shared understanding of what may impact match lists for both UME graduates and GME programs, leaving the Match somewhat less mysterious. While we understand the trend of graduates remaining at their home institutions for GME training, we are uncertain whether setting a goal for retention is reasonable, and so some mystery remains. We believe there is an invaluable opportunity for collaboration between UME and GME stakeholders to facilitate discussion about setting shared institutional goals. PMID- 27702433 TI - Effectiveness of hands-on tutoring and guided self-directed learning versus self directed learning alone to educate critical care fellows on mechanical ventilation - a pilot project. AB - BACKGROUND: Physicians require extensive training to achieve proficiency in mechanical ventilator (MV) management of the critically ill patients. Guided self directed learning (GSDL) is usually the method used to learn. However, it is unclear if this is the most proficient approach to teaching mechanical ventilation to critical care fellows. We, therefore, investigated whether critical care fellows achieve higher scores on standardized testing and report higher satisfaction after participating in a hands-on tutorial combined with GSDL compared to self-directed learning alone. METHODS: First-year Pulmonary and Critical Care Medicine (PCCM) fellows (n=6) and Critical Care Internal Medicine (CCIM) (n=8) fellows participated. Satisfaction was assessed using the Likert scale. MV knowledge assessment was performed by administering a standardized 25 question multiple choice pre- and posttest. For 2 weeks the CCIM fellows were exposed to GSDL, while the PCCM fellows received hands-on tutoring combined with GSDL. RESULTS: Ninety-three percentage (6 PCCM and 7 CCIM fellows, total of 13 fellows) completed all evaluations and were included in the final analysis. CCIM and PCCM fellows scored similarly in the pretest (64% vs. 52%, p=0.13). Following interventions, the posttest scores increased in both groups. However, no significant difference was observed based on the interventions (74% vs. 77%, p=0.39). The absolute improvement with the hands-on-tutoring and GSDL group was higher than GSDL alone (25% vs. 10%, p=0.07). Improved satisfaction scores were noted with hands-on tutoring. CONCLUSIONS: Hands-on tutoring combined with GSDL and GSDL alone were both associated with an improvement in posttest scores. Absolute improvement in test and satisfaction scores both trended higher in the hands-on tutorial group combined with GSDL group. PMID- 27702434 TI - RF-Burning Mouth Syndrome: New Treatments. PMID- 27702435 TI - Prevalence of Cancer in Adults With Congenital Heart Disease Compared With the General Population. AB - The prevalence rate of cancer among adult patients with congenital heart disease (CHD) in North America has not been previously described. The Quebec adult CHD database was used to determine the prevalence rate of cancer among adult patients with CHD measured as the number of adults with CHD and cancer alive in 2005 per 1,000 adults with CHD. This prevalence rate was compared with the prevalence rate of cancer in the general population of adults in Canada. Types of cancer among the CHD group were described by gender and age. Adult patients with CHD had a 1.6 to 2 times higher prevalence of cancer at 2, 5, and 10 years for both men and women. Overall, men had a greater prevalence of total cancers in all-time durations than did women. Breast, colon, and prostate cancer were the most common cancers reported in adults with CHD. In conclusion, we observed an increased prevalence of cancer among the adult CHD population of Quebec compared with the general Canadian population.

PMID- 27702437 TI - Endovascular repair versus open surgery in patients in the treatment of the ruptured of aneurysms abdominal. AB - INTRODUCTION: Rupture of abdominal aortic aneurysm is still a difficult challenge for the vascular surgeon due to the high perioperative mortality. The aim of our study is to describe the characteristics of the population as well as to compare morbidity and mortality in patients undergoing open surgery or endovascular repair in our center. METHODS: Database with 82 rAAA between January 2002 December 2014, studying two cohorts, open surgery and endovascular repair. Epidemiologic, clinical, surgical techniques, perioperative mortality and complications are analyzed. RESULTS: 82 rAAA cases were operated (men: 80, women: 2). Mean age 72+/-9.6 years. 76.8% (63 cases) was performed by open surgery. BACKGROUND: smokers 59, 7%, alcoholism 19.5%, DM 10.9%, AHT: 53.6%, dyslipidemia 30.5%. The most frequent clinical presentation was abdominal pain with lumbar irradiation: 50 cases (20.7% associating syncope). Overall hospital mortality was 58.5%. Hemodynamic shock prior to intervention was associated with increased mortality (p <.001). Anemia, leukocytosis, aneurysm size, sex and age did not show a statistically significant difference with respect to mortality (p>.05). The presence of iliac aneurysms was associated with increased mortality (p <.0045). Perioperative mortality in endovascular repair was 42%, and in open surgery was 63.5% (p>.05). Hospital stay was lower in the endovascular group (p=.3859). CONCLUSIONS: Hemodynamic shock and the presence of concomitant iliac aneurysms have a statistically significant association with perioperative mortality in both groups. We found clinically significant differences in mortality, complications and hospital stay when comparing both groups with better results for EVAR, without statistically significant differences.

PMID- 27702442 TI - Autoinflammatory diseases in adults. Clinical characteristics and prognostic implications. AB - Autoinflammatory diseases are clinical conditions with inflammatory manifestations that present in a periodic or persistent manner and are caused by acquired or hereditary disorders of the innate immune response. In general, these diseases are more common in childhood, but cases have been reported in adults and are therefore important for all specialists. There are few references on these diseases in adults due to their low prevalence and underdiagnosis. The aim of this study is to review the scientific literature on these disorders to systematise their clinical, prognostic and treatment response characteristics in adults. PMID- 27702441 TI - Effects of microcystin-LR and cylindrospermopsin on plant-soil systems: A review of their relevance for agricultural plant quality and public health. AB - Toxic cyanobacterial blooms are recognized as an emerging environmental threat worldwide. Although microcystin-LR is the most frequently documented cyanotoxin, studies on cylindrospermopsin have been increasing due to the invasive nature of cylindrospermopsin-producing cyanobacteria. The number of studies regarding the effects of cyanotoxins on agricultural plants has increased in recent years, and it has been suggested that the presence of microcystin-LR and cylindrospermopsin in irrigation water may cause toxic effects in edible plants. The uptake of these cyanotoxins by agricultural plants has been shown to induce morphological and physiological changes that lead to a potential loss of productivity. There is also evidence that edible terrestrial plants can bioaccumulate cyanotoxins in their tissues in a concentration dependent-manner. Moreover, the number of consecutive cycles of watering and planting in addition to the potential persistence of microcystin-LR and cylindrospermopsin in the environment are likely to result in groundwater contamination. The use of cyanotoxin-contaminated water for agricultural purposes may therefore represent a threat to both food security and food safety. However, the deleterious effects of cyanotoxins on agricultural plants and public health seem to be dependent on the concentrations studied, which in most cases are non-environmentally relevant. Interestingly, at ecologically relevant concentrations, the productivity and nutritional quality of some agricultural plants seem not to be impaired and may even be enhanced. However, studies assessing if the potential tolerance of agricultural plants to these concentrations can result in cyanotoxin and allergen accumulation in the edible tissues are lacking. This review combines the most current information available regarding this topic with a realistic assessment of the impact of cyanobacterial toxins on agricultural plants, groundwater quality and public health. PMID- 27702440 TI - Epigenetic Aging and Immune Senescence in Women With Insomnia Symptoms: Findings From the Women's Health Initiative Study. AB - BACKGROUND: Insomnia symptoms are associated with vulnerability to age-related morbidity and mortality. Cross-sectional data suggest that accelerated biological aging may be a mechanism through which sleep influences risk. A novel method for determining age acceleration using epigenetic methylation to DNA has demonstrated predictive utility as an epigenetic clock and prognostic of age-related morbidity and mortality. METHODS: We examined the association of epigenetic age and immune cell aging with sleep in the Women's Health Initiative study (N = 2078; mean 64.5 +/- 7.1 years of age) with assessment of insomnia symptoms (restlessness, difficulty falling asleep, waking at night, trouble getting back to sleep, and early awakenings), sleep duration (short sleep 5 hours or less; long sleep greater than 8 hours), epigenetic age, naive T cell (CD8+CD45RA+CCR7+), and late differentiated T cells (CD8+CD28-CD45RA-). RESULTS: Insomnia symptoms were related to advanced epigenetic age (beta +/- SE = 1.02 +/- 0.37, p = .005) after adjustments for covariates. Insomnia symptoms were also associated with more late differentiated T cells (beta +/- SE = 0.59 +/- 0.21, p = .006), but not with naive T cells. Self-reported short and long sleep duration were unrelated to epigenetic age. Short sleep, but not long sleep, was associated with fewer naive T cells (p < .005) and neither was related to late differentiated T cells. CONCLUSIONS: Symptoms of insomnia were associated with increased epigenetic age of blood tissue and were associated with higher counts of late differentiated CD8+ T cells. Short sleep was unrelated to epigenetic age and late differentiated cell counts, but was related to a decline in naive T cells. In this large population-based study of women in the United States, insomnia symptoms are implicated in accelerated aging. PMID- 27702443 TI - Brazilian propolis promotes immunomodulation on human cells from American Tegumentar Leishmaniasis patients and healthy donors infected with L. braziliensis. AB - American Tegumentar Leishmaniasis (ATL) is an infectious disease caused by Leishmania parasites with ineffective treatment. The properties of propolis have been studied in different experimental studies, however, few works have investigated the effects of propolis on human-derived peripheral blood mononuclear cells (PBMC) in leishmaniasis models. Thus, we investigate the immunomodulatory effects of propolis treatment on PBMC from ATL patients and on PBMC from healthy donors infected with Leishmania braziliensis. Our data demonstrate that propolis pretreatment shows immunomodulatory effects on both healthy donors and ATL patients adherent cells, increasing IL-4 and IL-17 and decreasing IL-10, in either the presence or absence of the L. braziliensis infection, demonstrating that propolis contributes with the decrease of the inflammation and could also contribute with parasite control. PMID- 27702444 TI - Increasing ankle push-off work with a powered prosthesis does not necessarily reduce metabolic rate for transtibial amputees. AB - Amputees using passive ankle-foot prostheses tend to expend more metabolic energy during walking than non-amputees, and reducing this cost has been a central motivation for the development of active ankle-foot prostheses. Increased push off work at the end of stance has been proposed as a way to reduce metabolic energy use, but the effects of push-off work have not been tested in isolation. In this experiment, participants with unilateral transtibial amputation (N=6) walked on a treadmill at a constant speed while wearing a powered prosthesis emulator. The prosthesis delivered different levels of ankle push-off work across conditions, ranging from the value for passive prostheses to double the value for non-amputee walking, while all other prosthesis mechanics were held constant. Participants completed six acclimation sessions prior to a data collection in which metabolic rate, kinematics, kinetics, muscle activity and user satisfaction were recorded. Metabolic rate was not affected by net prosthesis work rate (p=0.5; R2=0.007). Metabolic rate, gait mechanics and muscle activity varied widely across participants, but no participant had lower metabolic rate with higher levels of push-off work. User satisfaction was affected by push-off work (p=0.002), with participants preferring values of ankle push-off slightly higher than in non-amputee walking, possibly indicating other benefits. Restoring or augmenting ankle push-off work is not sufficient to improve energy economy for lower-limb amputees. Additional necessary conditions might include alternate timing or control, individualized tuning, or particular subject characteristics. PMID- 27702445 TI - Forensic sciences (anthropology/archaeology/pathology) and international criminal justice. PMID- 27702446 TI - The effect of mark enhancement techniques on the subsequent detection of saliva. AB - There appears to be a limited but growing body of research on the sequential analysis/treatment of multiple types of evidence. The development of an integrated forensic approach is necessary to maximise evidence recovery and to ensure that a particular treatment is not detrimental to other types of evidence. This study aims to assess the effect of latent and blood mark enhancement techniques (e.g. fluorescence, ninhydrin, acid violet 17, black iron-oxide powder suspension) on the subsequent detection of saliva. Saliva detection was performed by means of a presumptive test (Phadebas(r)) in addition to analysis by a rapid stain identification (RSID) kit test and confirmatory DNA testing. Additional variables included a saliva depletion series and a number of different substrates with varying porosities as well as different ageing periods. Examination and photography under white light and fluorescence was carried out prior to and after chemical enhancement. All enhancement techniques (except Bluestar(r) Forensic Magnum luminol) employed in this study resulted in an improved visualisation of the saliva stains, although the inherent fluorescence of saliva was sometimes blocked after chemical treatment. The use of protein stains was, in general, detrimental to the detection of saliva. Positive results were less pronounced after the use of black iron-oxide powder suspension, cyanoacrylate fuming followed by BY40 and ninhydrin when compared to the respective positive controls. The application of Bluestar(r) Forensic Magnum luminol and black magnetic powder proved to be the least detrimental, with no significant difference between the test results and the positive controls. The use of non-destructive fluorescence examination provided good visualisation; however, only the first few marks in the depletion were observed. Of the samples selected for DNA analysis only depletion 1 samples contained sufficient DNA quantity for further processing using standard methodology. The 28-day delay between sample deposition and collection resulted in a 5-fold reduction in the amount of useable DNA. When sufficient DNA quantities were recovered, enhancement techniques did not have a detrimental effect on the ability to generate DNA profiles. This study aims to contribute to a strategy for maximising evidence recovery and efficiency for the detection of latent marks and saliva. The results demonstrate that most of the enhancement techniques employed in this study were not detrimental to the subsequent detection of saliva by means of presumptive, confirmative and DNA tests. PMID- 27702447 TI - A method for rapid sampling and characterization of smokeless powder using sorbent-coated wire mesh and direct analysis in real time - mass spectrometry (DART-MS). AB - Improvised explosive devices (IEDs) are often used by terrorists and criminals to create public panic and destruction, necessitating rapid investigative information. However, backlogs in many forensic laboratories resulting in part from time-consuming GC-MS and LC-MS techniques prevent prompt analytical information. Direct analysis in real time - mass spectrometry (DART-MS) is a promising analytical technique that can address this challenge in the forensic science community by permitting rapid trace analysis of energetic materials. Therefore, we have designed a qualitative analytical approach that utilizes novel sorbent-coated wire mesh and dynamic headspace concentration to permit the generation of information rich chemical attribute signatures (CAS) for trace energetic materials in smokeless powder with DART-MS. Sorbent-coated wire mesh improves the overall efficiency of capturing trace energetic materials in comparison to swabbing or vacuuming. Hodgdon Lil' Gun smokeless powder was used to optimize the dynamic headspace parameters. This method was compared to traditional GC-MS methods and validated using the NIST RM 8107 smokeless powder reference standard. Additives and energetic materials, notably nitroglycerin, were rapidly and efficiently captured by the Carbopack X wire mesh, followed by detection and identification using DART-MS. This approach has demonstrated the capability of generating comparable results with significantly reduced analysis time in comparison to GC-MS. All targeted components that can be detected by GC MS were detected by DART-MS in less than a minute. Furthermore, DART-MS offers the advantage of detecting targeted analytes that are not amenable to GC-MS. The speed and efficiency associated with both the sample collection technique and DART-MS demonstrate an attractive and viable potential alternative to conventional techniques. PMID- 27702448 TI - Laser ablation coupled with DAPNe-NSI-MS applied to redacted documents. AB - Laser ablation has been applied to redacted documents, where the text has been concealed by other ink. This technique strips the redacting ink revealing the text that was once redacted. Once removed, a nanomanipulation technique is used to extract the ink of the underlying text where mass spectrometry is then implemented to analyze its ink chemistry. In order to facilitate microscopy with direct analyte-probed nanoextraction coupled to nanospray ionization mass spectrometry (DAPNe-NSI-MS), laser ablation must be executed prior to ink extraction. Laser ablation has a nondestructive approach of stripping the ink used to redact the document. Not only does this reveal the text, it clears an area for DAPNe to directly extract ink, in miniscule amounts, from the document without inducing destruction. The redacting ink was concluded to affect the aging process of the concealed handwritten ink more than the printed text. The redacted handwritten sample obtained higher relative peak area (%) values than the control samples (text that was not redacted) and the control for the printed text produced higher amounts of low molecular weight products than the sample. Implementing laser ablation on these samples could also affect the chemical properties of the underlying ink due to the additional UV radiation and plasma heating. Results indicate by using laser ablation to remove the redacting ink, the relative peak area of the underlying ink deviates by 1.25%. The thermal degradation of binding agents such as polymethylene, polyethylene glycol, and diethylene glycol was monitored by calculating the relative peak area for five days which, in turn, tracks the oxidation process. The relative peak area values were also used to determine the chemical kinetics of polyethylene glycol, where degradation and polymerization occur. PMID- 27702449 TI - Shoeprint retrieval: Core point alignment for pattern comparison. AB - PURPOSE: Shoeprint recognition has been widely used as forensic evidence in criminal cases. The purpose of this study is to propose a shoeprint retrieval method based on core point alignment for pattern analysis. METHOD: The proposed method firstly detects contour points in a black-and-white shoeprint image. These reliable contour points are selected to simulate the left and right sidelines of the shoeprint by a curve fitting method. Subsequently, the most concave points along the left and right sidelines can determine the core point of the shoeprint, thereby partitioning the shoeprint into circular regions. Next, the Zernike moments of the circular regions are calculated for pattern descriptions of each region. Finally, the Euclidean distance is measured to match the shoeprints with the same pattern. RESULT: The highest APR=0.726 is obtained from the first four Zernike moments with a radius of 90pixels and three baselines. The experimental results also show that the Zernike method in any order always outperforms the compared moment invariant and GLCM method. The experimental results also indicate that the core point is more stable than the gravity center in the both sets, because the standard deviation values of the core point are less than that of the gravity center. CONCLUSIONS: This study has verified that the proposed method can effectively align shoeprints for pattern comparison. PMID- 27702450 TI - The identification of emotions from gait. PMID- 27702451 TI - Sex estimation from the scapula in a contemporary Chilean population. AB - The scapula is valuable for sex estimation in human skeletons. Muscles provide protection to the scapula making it difficult to fracture, therefore increasing the potential for undamaged scapulae at forensic scenes. The goal of this project is to evaluate the accuracy of discriminant functions, created using an indigenous Guatemalan and contemporary Mexican population, when applied to a contemporary Chilean sample for estimation of sex from the scapula. The length of the glenoid cavity (LGC) and breadth of the glenoid cavity (BGC) were measured. The sample included 114 individuals (58 males and 56 females) with age ranges from 17 to 85years old. When the Guatemalan discriminant functions were applied to the Chilean sample they showed higher accuracy rates for sexing male scapulae (89.6% to 94.8%) than for sexing female scapulae (53.4% to 80.3%). When the Mexican discriminant functions were applied to the Chilean sample they showed higher accuracy rates for sexing female scapulae (82.1% to 96.4%) than for sexing male scapulae (56.9% to 89.6%). Size comparisons were made to a Guatemalan, Mexican, White American, and Greek population. Overall, in males and females of the Chilean population both left and right scapulae were larger than in the Guatemalan population but smaller than in the Mexican, White American, and Greek samples. Population-specific discriminant functions were created for the Chilean population with an overall sex classification accuracy rate of 80.7% to 86.0%. PMID- 27702452 TI - Discussion on how to implement a verbal scale in a forensic laboratory: Benefits, pitfalls and suggestions to avoid misunderstandings. AB - In a recently published guideline for evaluative reporting in forensic science, the European Network of Forensic Science Institutes (ENFSI) recommended the use of the likelihood ratio for the measurement of the value of forensic results. As a device to communicate the probative value of the results, the ENFSI guideline mentions the possibility to define and use a verbal scale, which should be unified within a forensic institution. This paper summarizes discussions held between scientists of our institution to develop and implement such a verbal scale. It intends to contribute to general discussions likely to be faced by any forensic institution that engages in continuous monitoring and improving of their evaluation and reporting format. We first present published arguments in favour of the use of such verbal qualifiers. We emphasise that verbal qualifiers do not replace the use of numbers to evaluate forensic findings, but are useful to communicate the probative value, since the weight of evidence in terms of likelihood ratio are still apprehended with difficulty by both the forensic scientists, especially in the absence of hard data, and the recipient of information. We further present arguments that support the development of the verbal scale that we propose. Recognising the limits of the use of such a verbal scale, we then discuss its disadvantages: it may lead to the spurious view according to which the value of the observations made in a given case is relative to other cases. Verbal qualifiers are also prone to misunderstandings and cannot be coherently combined with other evidence. We therefore recommend not using the verbal qualifier alone in a written statement. While scientists should only report on the probability of the findings - and not on the probability of the propositions, which are the duty of the Court - we suggest showing examples to let the recipient of information understand how the scientific evidence affects the probabilities of the propositions. To avoid misunderstandings, we also advise to mention in the statement what the results do not mean. Finally, we are of the opinion that if experts were able to coherently articulate numbers, and if recipients of information could properly handle such numbers, then verbal qualifiers could be abandoned completely. At that time, numerical expressions of probative value will be appropriately understood, as other numerical measures that most of us understand without the need of any further explanation, such as expressions for length or temperature.

AB - The present paper introduces the Science & Justice virtual special issue on measuring and reporting the precision of forensic likelihood ratios - whether this should be done, and if so how. The focus is on precision (aka reliability) as opposed to accuracy (aka validity). The topic is controversial and different authors are expected to express a range of nuanced opinions. The present paper frames the debate, explaining the underlying problem and referencing classes of solutions proposed in the existing literature. The special issue will consist of a number of position papers, responses to those position papers, and replies to the responses. PMID- 27702454 TI - What should a forensic practitioner's likelihood ratio be? AB - We argue that forensic practitioners should empirically assess and report the precision of their likelihood ratios. Once the practitioner has specified the prosecution and defence hypotheses they have adopted, including the relevant population they have adopted, and has specified the type of measurements they will make, their task is to empirically calculate an estimate of a likelihood ratio which has a true but unknown value. We explicitly reject the competing philosophical position that the forensic practitioner's likelihood ratio should be based on subjective personal probabilities. Estimates of true but unknown values are based on samples and are subject to sampling uncertainty, and it is standard practice to report the degree of precision of such estimates. We discuss the dangers of not reporting precision to the courts, and the problems with an alternative approach which instead reports a verbal expression corresponding to a pre-specified range of likelihood ratio values. Reporting precision as an interval requires an arbitrary choice of coverage, e.g., a 95% or a 99% credible interval. We outline a normative framework which a trier of fact could employ to make non-arbitrary use of the results of forensic practitioners' empirical calculations of likelihood ratios and their precision. PMID- 27702455 TI - Admitting to uncertainty in the LR. AB - In this paper I argue that, given our current state of knowledge, reporting uncertainty in the likelihood ratio is best practice. This may in time be replaced by reporting a Bayes factor, but we are currently unable to do this in all but the simplest of examples. PMID- 27702456 TI - An argument against presenting interval quantifications as a surrogate for the value of evidence. AB - In the various forensic science disciplines, recent analytical developments paired with modern statistical computational tools have led to the proliferation of adhoc techniques for quantifying the probative value of forensic evidence. Many legal and scientific scholars agree that the value of evidence should be reported as a likelihood ratio or a Bayes Factor. Quantifying the probative value of forensic evidence is subjected to many sources of variability and uncertainty. There is currently a debate on how to characterize the reliability of the value of evidence. Some authors have proposed associating a confidence/credible interval with the value of evidence assigned to a collection of forensic evidence. In this paper, we will discuss the reasons for our opinion that interval quantifications for the value of evidence should not be used directly in the Bayesian decision-making process to determine the support of the evidence for one of the two competing hypotheses. PMID- 27702457 TI - The LR does not exist. AB - More than 40years ago, De Finetti warned that probability is a misleading misconception when regarded as objectively existing exterior to the mind. According to De Finetti, probabilities are necessarily subjective, and quantify our belief in the truth of events in the real world. Given evidence of a shared feature of a trace and an accused, we apply this framework to assign an evidential value to this correspondence. Dividing 1 by the objectively existing proportion of the population sharing that feature would give that evidential value - expressed as a likelihood ratio (LR) - only if that proportion were known. As in practice the proportion can only be estimated, this leads some to project their sampling uncertainty - or precision - associated with the estimated proportion onto the likelihood ratio, and to report an interval. Limited data should limit our LR however, because as we will demonstrate the LR is given by what we know about the proportion rather than by the unknown proportion itself. Encapsulating all uncertainty - including sampling uncertainty of the proportion our LR reflects how much information we have retrieved from the feature regarding the trace's origin, based on our present knowledge. Not an interval but a number represents this amount of information, equal to the logarithm of the LR. As long as we know how to interpret the evidence with a well-defined probabilistic model, we know what our evidence is worth. PMID- 27702458 TI - Reframing the debate: A question of probability, not of likelihood ratio. AB - Evidential value is measured by a likelihood ratio. This ratio has two components, the probability, or probability density, of the evidence if the prosecution proposition is true and the probability (density) of the evidence if the defence proposition is true. It takes the form of a single value, even if these probabilities are subjective measures of belief of the reporting forensic scientist. PMID- 27702459 TI - Posterior distributions for likelihood ratios in forensic science. AB - Evaluation of evidence in forensic science is discussed using posterior distributions for likelihood ratios. Instead of eliminating the uncertainty by integrating (Bayes factor) or by conditioning on parameter values, uncertainty in the likelihood ratio is retained by parameter uncertainty derived from posterior distributions. A posterior distribution for a likelihood ratio can be summarised by the median and credible intervals. Using the posterior mean of the distribution is not recommended. An analysis of forensic data for body height estimation is undertaken. The posterior likelihood approach has been criticised both theoretically and with respect to applicability. This paper addresses the latter and illustrates an interesting application area. PMID- 27702460 TI - Using sensitivity analyses in Bayesian Networks to highlight the impact of data paucity and direct future analyses: a contribution to the debate on measuring and reporting the precision of likelihood ratios. AB - Bayesian networks are being increasingly used to address complex questions of forensic interest. Like all probabilities, those that underlie the nodes within a network rely on structured data and knowledge. Obviously, the more structured data we have, the better. But, in real life, the numbers of experiments that can be carried out are limited. It is thus important to know if/when our knowledge is sufficient and when one needs to perform further experiments to be in a position to report the value of the observations made. To explore the impact of the amount of data that are available for assessing results, we have constructed Bayesian Networks and explored the sensitivity of the likelihood ratios to changes to the data that underlie each node. Bayesian networks are constructed and sensitivity analyses performed using freely available R libraries (gRain and BNlearn). We demonstrate how the analyses can be used to yield information about the robustness provided by the data used to inform the conditional probability table, and also how they can be used to direct further research for maximum effect. By maximum effect, we mean to contribute with the least investment to an increased robustness. In addition, the paper investigates the consequences of the sensitivity analysis to the discussion on how the evidence shall be reported for a given state of knowledge in terms of underpinning data.

PMID- 27702464 TI - 3D printing-assisted osteotomy treatment for the malunion of lateral tibial plateau fracture. AB - INTRODUCTION: Osteotomy and internal fixation are usually the most effective way to treat the malunion of lateral tibial plateau fractures, and the accuracy of the osteotomy is still a challenge for surgeons. This is a report of a series of prospectively study of osteotomy treatment for the malunion of lateral plateau fractures with the aid of 3D printing technology. METHODS: A total of 7 patients with malunion of lateral tibial plateau fractures were enrolled in the study between September 2012 to September 2014 and completed follow up. CT image data were used for 3D reconstruction, and individually 3D printed models were used for accurate measurements and detail osteotomy procedures planning. Under the premeditated operation plan, the osteotomy operations were performed. Patients were invited for follow-up examinations at 2 and 6 weeks and then at intervals of 6 to 8 weeks until 12 months or more. RESULTS: Mean age of the patients was 44 years (range 30-52 years), 3 cases were result of fall injuries, 2 were traffic accidents and 2 were sports injuries. Among the cases, one accompanied with craniocerebra trauma, one with pelvic fracture, one accompanied with both. According to the Schatzker Tibial Plateau classification, the original fracture type were 3 type I, 1 type II and 3 type III. The lateral tibial plateau collapse ranges from 4 mm-12mm, with an average of 9.4mm. All the operations were successfully completed, the average operation time was 77.1min (range 70-90 min), the average intraoperative blood loss was 121.4ml (range 90-180ml), the mean follow-up time was 14.4 months (range 12-18 months), and the average healing time of the osteotomy fragments was 12 weeks (range 11-13 weeks). The difference between preoperative and postoperative Rasmussen scores were statistically significant (P<0.05). All the patients were obtained functional recovery, with no complications. CONCLUSION: 3D printing technology is helpful to accurately design osteotomy operation, reduce the risk of postoperative deformity, decrease intraoperative blood loss, shorten the operation time, and can effectively improve the treatment effect. PMID- 27702465 TI - Evaluation and Management of Sleep Disorders in the Hand Surgery Patient. AB - Despite posing a significant public health threat, sleep disorders remain poorly understood and often underdiagnosed and mismanaged. Although sleep disorders are seemingly unrelated, hand surgeons should be mindful of these because numerous conditions of the upper extremity have known associations with sleep disturbances that can adversely affect patient function and satisfaction. In addition, patients with sleep disorders are at significantly higher risk for severe, even life-threatening medical comorbidities, further amplifying the role of hand surgeons in the recognition of this condition.

AB - PURPOSE: To determine whether there is a correlation between the cross-sectional area (CSA) of the median nerve, as measured using ultrasound, and the distal motor and/or sensory latencies as measured on nerve conduction studies. METHODS: Patients with clinical signs and symptoms of carpal tunnel syndrome were prospectively enrolled in this study. Subjects underwent ultrasound measurement of the CSA of the median nerve at the carpal tunnel inlet by a fellowship-trained hand surgeon, followed by nerve conduction studies (NCS) by a certified electrodiagnostic technician who was blinded to the results of the ultrasound examination. Pearson correlations were performed to compare CSA and NCS. RESULTS: Pearson correlation was r = 0.57 between CSA and distal motor latency and r = 0.47 between CSA and distal sensory latency. Correlation was r = 0.81 between distal motor latency and distal sensory latency. CONCLUSIONS: There is a correlation between CSA of the median nerve and NCS. Further research is necessary to determine which test correlates better with patient symptoms and function. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic II. PMID- 27702469 TI - A new generation approach in enzyme immobilization: Organic-inorganic hybrid nanoflowers with enhanced catalytic activity and stability. AB - Many different micro and nano sized materials have been used for enzymes immobilization in order to increase their catalytic activity and stability. Generally, immobilized enzymes with conventional immobilization techniques exhibit improved stability while their activity is lowered compared to free enzymes. Recently, an elegant immobilization approach was discovered in synthesis of flower-like organic-inorganic hybrid nanostructures with extraordinary catalytic activity and stability. In this novel immobilization strategy, proteins (enzymes) and metal ions acted as organic and inorganic components, respectively to form hybrid nanoflowers (hNFs). It is demonstrated that the hNFs highly enhanced catalytic activities and stability in a wide range of experimental conditions (pHs, temperatures and salt concentration, etc.) compared to free and conventionally immobilized enzymes. This review mainly discussed the synthesis, characterization, development and applications of organic-inorganic hybrid nanoflowers formed of various enzymes and metal ions and explained potential mechanism underlying enhanced catalytic activity and stability. PMID- 27702468 TI - Electrospun polyvinyl alcohol/bovine serum albumin biocomposite membranes for horseradish peroxidase immobilization. AB - Electrospinning, a simple and versatile method to fabricate nanofibrous supports, has attracted attention in the field of enzyme immobilization. Biocomposite nanofibers were fabricated from mixed PVA/BSA solution and the effects of glutaraldehyde treatment, initial BSA concentration and PVA concentration on protein loading were investigated. Glutaraldehyde cross-linking significantly decreased protein release from nanofibers and BSA loading reached as high as 27.3% (w/w). In comparison with the HRP immobilized into the nascent nanofibrous membrane, a significant increase was observed in the activity retention of the enzyme immobilized into the PVA/BSA biocomposite nanofibers. The immobilized HRP was able to tolerate much higher concentrations of hydrogen peroxide than the free enzyme and thus the immobilized enzyme did not demonstrate substrate inhibition. The immobilized HRP retained~50% of the free enzyme activity at 6.4mM hydrogen peroxide and no significant variation was observed in the KM value of the enzyme for hydrogen peroxide after immobilization. In addition, reusability tests showed that the residual activity of the immobilized HRP were 73% after 11 reuse cycles. Together, these results demonstrate efficient immobilization of HRP into electrospun PVA/BSA biocomposite nanofibers and provide a promising immobilization strategy for biotechnological applications. PMID- 27702470 TI - Improved efficiency of a novel methyl parathion hydrolase using consensus approach. AB - A methyl parathion hydrolase (MPH) gene, bjmpd, was cloned from a newly isolated MP-degrading bacterial strain, Burkholderia jiangsuensis MP-1T and heterologously expressed in Escherichia coli BL21 (DE3). Although the amino acid sequence of the bjmpd-encoded enzyme, named BjMPH, differed from that of MPH from Pseudomonas sp. WBC-3 (PsMPH) in only three residues, Ser132, Val247 and Ala267, a significantly higher specific activity towards MP was exhibited by BjMPH than PsMPH. Among them, Ala267 was identified as a key site affecting the catalytic efficiency, and it was rather conservative (Ala or Ser) in homologous proteins, suggesting that a simple substitution of the residue in conservative site with another conservative residue based on the consensus sequence approach might possibly enhance the catalytic efficiency of the MP-degrading enzyme. Inspired by such an observation, we identified a new mutant, BjMPHT64N, exhibiting 3.78-fold higher catalytic efficiency (kcat/KM) towards MP than its wild-type, reaching 4.20*106M-1s-1. The mutant BjMPHT64N also displayed enhanced reactivities (kcat/KM) towards other organophosphorus pesticides. Homology-modelling analysis indicates that enhanced polar contacts of the 64th residue in this mutant may contribute to stabilizing the structure of the enzyme and promote the interactions between enzyme and substrate. This study generated an efficient MP-degrading enzyme, and provides useful information for enhancing the catalytic efficiency of MPHs via conservative residue substitution based on the consensus approach. PMID- 27702471 TI - Characterization of a Cellulomonas fimi exoglucanase/xylanase-endoglucanase gene fusion which improves microbial degradation of cellulosic biomass. AB - Effective degradation of cellulose requires multiple classes of enzyme working together. However, naturally occurring cellulases with multiple catalytic domains seem to be rather rare in known cellulose-degrading organisms. A fusion protein made from Cellulomonas fimi exo- and endo- glucanases, Cex and CenA which improves breakdown of cellulose is described. A homologous carbohydrate binding module (CBM-2) present in both glucanases was fused to give a fusion protein CxnA. CxnA or unfused constructs (Cex+CenA, Cex, or CenA) were expressed in Escherichia coli and Citrobacter freundii. The latter recombinant strains were cultured at the expense of cellulose filter paper. The expressed CxnA had both exo- and endo- glucanase activities. It was also exported to the supernatant as were the non-fused proteins. In addition, the hybrid CBM from the fusion could bind to microcrystalline cellulose. Growth of C. freundii expressing CxnA was superior to that of cells expressing the unfused proteins. Physical degradation of filter paper was also faster with the cells expressing fusion protein than the other constructs. Our results show that fusion proteins with multiple catalytic domains can improve the efficiency of cellulose degradation. Such fusion proteins could potentially substitute cloning of multiple enzymes as well as improving product yields. PMID- 27702472 TI - Evaluation of cysteine ethyl ester as efficient inducer for glutathione overproduction in Saccharomyces spp. AB - Economical yeast based glutathione (GSH) production is a process that is influenced by several factors like raw material and production costs, biomass production and efficient biotransformation of adequate precursors into the final product GSH. Nowadays the usage of cysteine for the microbial conversion into GSH is industrial state of practice. In the following study, the potential of different inducers to increase the GSH content was evaluated by means of design of experiments methodology. Investigations were executed in three natural Saccharomyces strains, S. cerevisiae, S. bayanus and S. boulardii, in a well suited 50ml shake tube system. Results of shake tube experiments were confirmed in traditional baffled shake flasks and finally via batch cultivation in lab scale bioreactors under controlled conditions. Comprehensive studies showed that the usage of cysteine ethyl ester (CEE) for the batch-wise biotransformation into GSH led up to a more than 2.2 times higher yield compared to cysteine as inducer. Additionally, the intracellular GSH content could be significantly increased for all strains in terms of 2.29+/-0.29% for cysteine to 3.65+/-0.23% for CEE, respectively, in bioreactors. Thus, the usage of CEE provides a highly attractive inducing strategy for the GSH overproduction.

AB - Hydrogenases are enzymes that play a key role in controlling excess reducing equivalents in both photosynthetic and anaerobic organisms. This enzyme is viewed as potentially important for the industrial generation of hydrogen gas; however, insufficient hydrogen production has impeded its use in a commercial process. Here, we explore the potential to circumvent this problem by directly evolving the Fe-Fe hydrogenase genes from two species of Clostridia bacteria. In addition, a computational model based on these mutant sequences was developed and used as a predictive aid for the isolation of enzymes with even greater efficiency in hydrogen production. Two of the improved mutants have a logarithmic increase in hydrogen production in our in vitro assay. Furthermore, the model predicts hydrogenase sequences with hydrogen productions as high as 540-fold over the positive control. Taken together, these results demonstrate the potential of directed evolution to improve the native bacterial hydrogenases as a first step for improvement of hydrogenase activity, further in silico prediction, and finally, construction and demonstration of an improved algal hydrogenase in an in vivo assay of C. reinhardtii hydrogen production. PMID- 27702474 TI - Enhanced catalytic efficiency of endo-beta-agarase I by fusion of carbohydrate binding modules for agar prehydrolysis. AB - Recently, Microbulbifer thermotolerans JAMB-A94 endo-beta-agarase I was expressed as catalytic domain (GH16) without a carbohydrate-binding module (CBM). In this study, we successfully constructed different fusions of GH16 with its original CBM6 and CBM13 derived from Catenovulum agarivorans. The optimum temperature and pH for fusions GH16-CBM6, GH16-CBM13, GH16-CBM6-CBM13 and GH16-CBM13-CBM6 were similar to GH16, at 55 degrees C and pH 7. All the constructed fusions significantly enhanced the GH16 affinity (Km) and the catalytic efficiency (Kcat/Km) toward agar. Among them, GH16-CBM6-CBM13 exhibited the highest agarolytic activity, for which Km decreased from 3.67 to 2.11mg/mL and Kcat/Km increased from 98.6 (mg/mL)-1sec-1 to 400.6 (mg/mL)-1sec-1. Moreover, all fusions selectively increased GH16 binding ability to agar, in which the highest binding ability of 95% was obtained with fusion GH16-CBM6-CBM13. Melted agar was prehydrolyzed with GH16-CBM6-CBM13, resulting in a degree of liquefaction of 45.3% and reducing sugar yield of 14.2%. Further addition of Saccharophagus degradans agarolytic enzymes resulted in mono-sugar yields of 35.4% for galactose and 31.5% for 3,6-anhydro-l-galactose. There was no pH neutralization step required and no 5-hydroxymethylfurfural detected, suggesting the potential of a new enzymatic prehydrolysis process for efficient production of bio-products such as biofuels. PMID- 27702475 TI - Overproduction and characterization of a lytic polysaccharide monooxygenase in Bacillus subtilis using an assay based on ascorbate consumption. AB - Lytic polysaccharide monooxygenases (LPMOs) are copper ion-containing enzymes that degrade crystalline polysaccharides, such as cellulose or chitin, through an oxidative mechanism. To the best of our knowledge, there are no assay methods for the direct characterization of LPMOs that degrade substrates without coupled enzymes. As such, in this study, a coupled enzyme-free assay method for LPMOs was developed, which is based on measuring the consumption of ascorbic acid used as an external electron donor for LPMOs. To establish this new assay method, a chitin-active LPMO from Bacillus atrophaeus (BatLPMO10) was cloned as a model enzyme. An expression system using B. subtilis as the host cell yielded a simple purification process without complicated periplasmic fractionation, as well as improved productivity by 3.7-fold higher than that of Escherichia coli BL21(DE3). At the optimum pH determined using a newly developed assay, BatLPMO10 showed the highest activity in terms of promoting chitin degradation by a chitinase. In addition, the assay method indicated that BatLPMO10 was inhibited by sodium ions, and BatLPMO10 and a chitinase mutually enhanced each other's activities upon degrading chitin as the substrate. In conclusion, this hydrolase-free ascorbate assay allows quantitative analysis of BatLPMO10 without a coupled enzyme. PMID- 27702477 TI - Identification of a novel cellulose-binding domain within the endo-beta-1,4 xylanase KRICT PX-3 from Paenibacillus terrae HPL-003. AB - The model 3-D structure of xylanase KRICT PX3 (JF320814) identified by DNA sequence analysis revealed a catalytic domain and CBM4-9 which functions as a xylan binding domain (XBD). To identify its role in xylan hydrolysis, six expression plasmids were constructed encoding the N-terminal CBM plus the catalytic domain or different glycosyl hydrolases, and the biochemical properties of the recombinant enzymes were compared to the original structure of PX3 xylanase. All six of the recombinant xylanases with the addition of CBM in the pIVEX-GST expression vector showed no improved PX3 hydrolytic activity. However, the absence of the CBM domain resulted in a decrement of 40% in thermostability, movement of the optimal temperature from 55 degrees C to 45 degrees C, alteration of the optimal pH range from 5-10 to 6-8, and reduction of the enzymatic activity to one-second under the same condition, respectively. The putative XBD in PX3 comprises a new N-terminal domain homologous to the catalytic thermostabilizing domains from other xylanases. Analysis of the main products released from xylan indicate that the recombinant enzymes act as endo-1,4-beta-xylanases but differ in their hydrolysis of xylan from beech wood, birch wood, and oat spelt. PMID- 27702476 TI - Production of steviol from steviol glucosides using beta-glycosidase from Sulfolobus solfataricus. AB - Steviol is a diterpene isolated from the plant Stevia rebaudiana that has a potential role as an antihyperglycemic agent by stimulating insulin secretion from pancreatic beta cells and also has significant potential to diminish the renal clearance of anionic drugs and their metabolites. In this study, the lacS gene, which encodes a thermostable beta-glycosidase (SSbgly) enzyme from the extremely thermoacidophillic archaeon Sulfolobus solfataricus, was cloned and expressed in E. coli Rossetta BL21(DE3)pLyS using lactose as an inducer. Through fermentation, SSbgly was expressed as a 61kDa protein with activity of 24.3U/mg and the OD600 of 23 was reached after 18h induction with 10mM lactose. Purified protein was obtained by Ni-Sepharose chromatography with a yield of 92.3%. SSbgly hydrolyzed steviol glycosides to produce steviol with a yield of 99.2%. The optimum conditions for steviol production were 50U/ml SSbgly and 90mg/ml Ste at 75 degrees C as determined by the response surface method. PMID- 27702479 TI - Enhancing activity and thermostability of lipase A from Serratia marcescens by site-directed mutagenesis. AB - Lipases as significant biocatalysts had been widely employed to catalyze various chemical reactions such as ester hydrolysis, ester synthesis, and transesterification. Improving the activity and thermostability of enzymes is desirable for industrial applications. The lipase of Serratia marcescens belonging to family I.3 lipase has a very important pharmaceutical application in production of chiral precursors. In the present study, to achieve improved lipase activity and thermostability, using computational predictions of protein, four mutant lipases of SML (MutG2P, MutG59P, Mut H279K and MutL613WA614P) were constructed by site-directed mutagenesis. The recombinant mutant proteins were over-expressed in E. coli and purified by affinity chromatography on the Ni-NTA system. Circular dichroism spectroscopy, differential scanning calorimetry and kinetic parameters (Km and kcat) were determined. Our results have shown that the secondary structure of all lipases was approximately similar to one another. The MutG2P and MutG59P were more stable than wild type by approximately 2.3 and 2.9 in T1/2, respectively. The catalytic efficiency (kcat/Km) of MutH279K was enhanced by 2-fold as compared with the wild type (p<0.05). These results indicate that using protein modeling program and creating mutation, can enhance lipase activity and/or thermostability of SML and it also could be used for improving other properties of enzyme to the desired requirements as well as further mutations. PMID- 27702478 TI - Facile modulation of enantioselectivity of thermophilic Geobacillus zalihae lipase by regulating hydrophobicity of its Q114 oxyanion. AB - Site-directed mutagenesis of the oxyanion-containing amino acid Q114 in the recombinant thermophilic T1 lipase previously isolated from Geobacillus zalihae was performed to elucidate its role in the enzyme's enantioselectivity and reactivity. Substitution of Q114 with a hydrophobic methionine to yield mutant Q114M increased enantioselectivity (3.2-fold) and marginally improved reactivity (1.4-fold) of the lipase in catalysing esterification of ibuprofen with oleyl alcohol. The improved catalytic efficiency of Q114L was concomitant with reduced flexibility in the active site while the decreased enantioselectivity of Q114L could be directly attributed to diminished electrostatic repulsion of the substrate carboxylate ion that rendered partial loss in steric hindrance and thus enantioselectivity. The highest E-values for both Q114L (E-value 14.6) and Q114M (E-value 48.5) mutant lipases were attained at 50 degrees C, after 12-16h, with a molar ratio of oleyl alcohol to ibuprofen of 1.5:1 and at 2.0% (w/v) enzyme load without addition of molecular sieves. Pertinently, site-directed mutagenesis on the Q114 oxyanion of T1 resulted in improved enantioselectivity and such approach may be applicable to other lipases of the same family. We demonstrated that electrostatic repulsion phenomena could affect flexibility/rigidity of the enzyme substrate complex, aspects vital for enzyme activity and enantioselectivity of T1. PMID- 27702480 TI - A new strategy for strain improvement of Aurantiochytrium sp. based on heavy-ions mutagenesis and synergistic effects of cold stress and inhibitors of enoyl-ACP reductase. AB - Developing a strain with high docosahexaenoic acid (DHA) yield and stable fermenting-performance is an imperative way to improve DHA production using Aurantiochytrium sp., a microorganism with two fatty acid synthesis pathways: polyketide synthase (PKS) pathway and Type I fatty acid synthase (FAS) pathway. This study investigated the growth and metabolism response of Aurantiochytrium sp. CGMCC 6208 to two inhibitors of enoyl-ACP reductase of Type II FAS pathway (isoniazid and triclosan), and proposed a method of screening high DHA yield Aurantiochytrium sp. strains with heavy ion mutagenesis and pre-selection by synergistic usage of cold stress (4 degrees C) and FAS inhibitors (triclosan and isoniazid). Results showed that (1) isoniazid and triclosan have positive effects on improving DHA level of cells; (2) mutants from irradiation dosage of 120Gy yielded more DHA compared with cells from 40Gy, 80Gy treatment and wild type; (3) DHA contents of mutants pre-selected by inhibitors of enoyl-ACP reductase of Type II FAS pathway (isoniazid and triclosan)at 4 degrees C, were significantly higher than that of wild type; (4) compared to the wild type, the DHA productivity and yield of a mutant (T-99) obtained from Aurantiochytrium sp. CGMCC 6208 by the proposed method increased by 50% from 0.18 to 0.27g/Lh and 30% from 21 to 27g/L, respectively. In conclusion, this study developed a feasible method to screen Aurantiochytrium sp. with high DHA yield by a combination of heavy-ion mutagenesis and mutant-preselection by FAS inhibitors and cold stress. PMID- 27702481 TI - Biosynthesis of optically pure chiral alcohols by a substrate coupled and biphasic system with a short-chain dehydrogenase from Streptomyces griseus. AB - The increasing demand for biocatalysts in synthesizing enantiomerically pure chiral alcohols results from the outstanding characteristics of enzymes in reaction, economic, ecological issues. Many carbonyl reductases for producing chiral alcohols have been reported but there is still a lack of good catalytic efficacies. Herein, five carbonyl reductases from different Streptomyces were discovered by the strategy of genome mining. These reductases were overexpressed, and we chose SgCR for further study as it owned better enzyme activity. This protein was purified to apparent homogeneity, and its amino acid sequence was analyzed in comparison with that of the reported SDRs. The biocatalytic properties of SgCR were investigated, and this enzyme was confirmed to have the ability to convert various prochiral ketones into highly optically active alcohols. SgCR exhibited the highest activity towards ethyl 4-chloro-3 oxobutanoate (COBE) and the corresponding product ethyl (S)-4-chloro-3 hydroxybutanoate ((S)-CHBE) was obtained with high yield and excellent e.e. value by optimizing the biphasic system. Eventually, using isopropanol as the co substrate for NADH recycling in the substrate-coupled reaction, the yield and enantioselectivity of (S)-CHBE were obtained at the values of 90% and 99%, respectively. These results indicate that SgCR is a promising boicatalyst for the synthesis of chiral alcohols in industry.

AB - We had previously investigated the role of a loop on the activity and conformational stability of chondroitinase ABC Iota (cABC Iota) by constructing some representative mutants in which a network interaction around Asp689 was manipulated. Here we extended our study by measuring the proteolytic resistance, long term and thermal stability as well as unfolding kinetics of these variants. Long term stability data at 4 and 25 degrees C for 3 weeks indicates that all mutants remain considerably active at 4 degrees C. Thermoinactivation rates for all variants shows that the wild type (WT) enzyme retained 50% of its activity after 2min keeping at 40 degrees C, while L701T, H700N and H700N/L701T as conformationally stabilized variants, have slower inactivation rate. It was also found that compact and thermodynamically stabilized variants are more resistant to tryptolytic digestion. Also, kinetic curves of chemical unfolding of the enzyme variants from stopped-flow fluorescence measurements were best fitted into a three-exponential function with three rate constants and corresponding amplitudes. We found that the energy barrier of the fast unfolding phase is lower in stabilized variants; while the amplitude of this phase to the whole amplitude of the unfolding reaction is lower than that of destabilized variants, indicating more population of stabilized mutants unfold via slower unfolding phase. We concluded that the rate of local conformational change alone is not the same that is expected from global thermodynamic stability; however the corresponding amplitude can compensate the rate constant toward thermodynamic stability.

AB - 1,2,4-Butanetriol (BT) and related derivatives have been widely used in many fields, especially in the military and in medicine. In this paper, we systematically optimized the BT biosynthetic pathway. We first investigated the activities of various NADH dependent aldehyde reductases (ALRs), which catalyze the fourth reaction in the four-step pathway for BT production from xylose in E. coli, and found that a combination of multiple endogenous enzymes catalyzed aldehyde reduction in the BT production bioprocess and that YqhD in E. coli was a main ALR for BT production. In addition, ADH2 from Saccharomyces cerevisiae can effectively catalyze 3,4-dihydroxybutanal to BT. Also, YjhG was identified as the major xylonate dehydratase and was co-overexpressed with YqhD, resulting in an improvement of BT production by 30%. Moreover, we identified and eliminated the competing branch pathway by inactivating 2-keto acid reductases (yiaE). Finally, the combination of these approaches led to BT production of 5.1g/L. In summary, our study provides insights into the biosynthetic pathway for BT production, demonstrates an effective strategy to enhance BT production, and paves the way toward in-depth research on BT biosynthesis.

AB - In this study, this protein was overexpressed in yeast cells grown on trehalose containing medium to assess its impact on yeast vacuolar activity. ATH was confirmed to be located in both cell surface and vacuoles and the overexpression of ATH was observed to decrease vacuolar activity. Therefore, an assumption was suggested to explain this phenomenon as follows: when grown on containing trehalose medium, the ATH localization at cellular periplasm, but not the vacuole, is prioritized to utilize the extracellular trehalose for cell growth. The multivesicular body pathway (MVB pathway) via which ATH is transported into vacuoles is believed to be down-regulated to favor the accumulation of ATH at cell surface area. By extension, other vacuolar proteins travelling through MVB pathway to reach yeast vacuoles likely also suffer the down regulation. It can be concluded that acid trehalase may contribute down regulation of other vacuolar proteins through MVB pathway. This study suggests that it is a potential of acid trehalase (ATH) on impaired activity of yeast vacuolar. PMID- 27702483 TI - Matrix metalloproteinases as reagents for cell isolation. AB - Cell isolation methods for therapeutic purposes have seen little advancement over the years. The original methods of stem cell and islet isolation using bacterial collagenases were developed in the early 1980s and are still used today. Bacterial collagenases are subject to autodegradation, and isolates obtained with these enzymes may be contaminated with endotoxins, reducing cell viability and contributing to toxicity in downstream applications. Here we describe a novel method for isolation of mesenchymal stem cells from adipose tissue (ADSC) utilizing recombinantly produced matrix metalloproteases (MMPs). The ADSCs isolated by MMPs displayed essentially identical morphological and phenotypical characteristics to cells isolated by bacterially-derived collagenase I and LiberaseTM. Samples isolated with MMPs and LiberaseTM had comparable levels of CD73, CD90, and CD105. The adipogenic and osteogenic potential of the ADSCs isolated by MMPs was retained as compared to cells isolated with LiberaseTM. However, ADSCs isolated by LiberaseTM displayed 6% contamination with other cells as per negative markers revealed by PE staining, as opposed to<1% for all MMP treated samples. MMP-based cell isolation may contribute to optimization of transplantation technology. PMID- 27702486 TI - Effect of sulfonated lignin on enzymatic activity of the ligninolytic enzymes Calpha-dehydrogenase LigD and beta-etherase LigF. AB - NAD+-dependent Calpha-dehydrogenase LigD and glutathione-dependent beta-etherase LigF which selectively cleave the beta-O-4 aryl ether linkage present in lignin, are key-enzymes for the biocatalytic depolymerization of lignin. However, the catalytic efficiency of the two enzymes is low when they are used to break down the beta-aryl ether linkage in natural lignin. When sulfonated lignin was added to LigF hydrolysis reactions, the conversion rate of MPHPV decreased significantly from 99.5% to 32.6%. On the contrary, sulfonated lignin has little affection on LigD, which the conversion rate of GGE only decreased from 41.7% to 41%. The strong nonspecific interactions of enzymes onto sulfonated lignin detected by surface plasmon resonance (SPR) and isothermal titration calorimetric (ITC) was obvious and universal, which can reduce enzyme activity of many enzymes, including ligninolytic enzyme beta-etherase LigF. To elucidate the exact mechanisms by which beta-etherase LigF interact with lignin, molecular modeling was applied. Finally, analysis on catalytic efficiency of LigD and LigF in different concentrations and molecular weights of sulfonated lignin, solution ionic strength, pH, temperature and concentration of Tween 80 revealed that electrostatic interactions and hydrophobic interactions play important roles in absorption between LigF and sulfonated lignin. PMID- 27702487 TI - Attenuating l-lysine production by deletion of ddh and lysE and their effect on l threonine and l-isoleucine production in Corynebacterium glutamicum. AB - The fermentative production of l-threonine and l-isoleucine with Corynebacterium glutamicum is usually accompanied by the by-production of l-lysine, which shares partial biosynthesis pathway with l-threonine and l-isoleucine. Since the direct precursor for l-lysine synthesis, diaminopimelate, is a component of peptidoglycan and thus essential for cell wall synthesis, reducing l-lysine by production could be troublesome. Here, a basal strain with eliminated l-lysine production was constructed from the wild type C. glutamicum ATCC13869 by deleting the chromosomal ddh and lysE. Furthermore, the basal strain as well as the ddh single mutant strain was engineered for l-threonine production by over-expressing lysC1, hom1 and thrB, and for l-isoleucine production by over-expressing lysC1, hom1, thrB and ilvA1. Fermentation experiments with the engineered strains showed that (i) deletion of ddh improved l-threonine production by 17%, and additional deletion of lysE further improved l-threonine production by 28%; (ii) deletion of ddh improved l-isoleucine production by 8% and improved cell growth by 21%, whereas additional deletion of lysE had no further influence on both l-isoleucine production and cell growth; (iii) l-lysine by-production was reduced by 95% and 86% in l-threonine and l-isoleucine production, respectively, by deletion of ddh and lysE. This is the first report on improving l-threonine and l-isoleucine production by deleting ddh and lysE in C. glutamicum. The results demonstrate deletion of ddh and lysE as an effective strategy to reduce l-lysine by production without surrendering the cell growth of C. glutamicum. PMID- 27702488 TI - Phylogeny, classification and metagenomic bioprospecting of microbial acetyl xylan esterases. AB - Acetyl xylan esterases (AcXEs), also termed xylan deacetylases, are broad specificity Carbohydrate-Active Enzymes (CAZymes) that hydrolyse ester bonds to liberate acetic acid from acetylated hemicellulose (typically polymeric xylan and xylooligosaccharides). They belong to eight families within the Carbohydrate Esterase (CE) class of the CAZy database. AcXE classification is largely based on sequence-dependent phylogenetic relationships, supported in some instances with substrate specificity data. However, some sequence-based predictions of AcXE encoding gene identity have proved to be functionally incorrect. Such ambiguities can lead to mis-assignment of genes and enzymes during sequence data-mining, reinforcing the necessity for the experimental confirmation of the functional properties of putative AcXE-encoding gene products. Although one-third of all characterized CEs within CAZy families 1-7 and 16 are AcXEs, there is a need to expand the sequence database in order to strengthen the link between AcXE gene sequence and specificity. Currently, most AcXEs are derived from a limited range of (mostly microbial) sources and have been identified via culture-based bioprospecting methods, restricting current knowledge of AcXEs to data from relatively few microbial species. More recently, the successful identification of AcXEs via genome and metagenome mining has emphasised the huge potential of culture-independent bioprospecting strategies. We note, however, that the functional metagenomics approach is still hampered by screening bottlenecks. The most relevant recent reviews of AcXEs have focused primarily on the biochemical and functional properties of these enzymes. In this review, we focus on AcXE phylogeny, classification and the future of metagenomic bioprospecting for novel AcXEs. PMID- 27702489 TI - Utilizing intein-mediated protein cleaving for purification of uricase, a multimeric enzyme. AB - Uric acid, a side product of nucleotide metabolism, should be cleared from blood stream since its accumulation can cause cardiovascular diseases and gout. Uricase (urate oxidase) converts uric acid to 5-hydroxyisourate, but it is absent in human and other higher apes. Yet, the recombinant form of uricase, Rasburicase, is now commercially available to cure tumor lysis syndrome by lowering serum uric acid level. Developing new methods to efficiently purify pharmaceutical proteins like uricase has attracted researchers' attention. Self-cleaving intein mediated single column purification is one of these novel approaches. Self-cleaving inteins are modified forms of natural inteins that can excise and join only at one junction site. In this study, the synthetic gene of Aspergillus flavus uricase, a homotetrameric protein, was cloned into pTXB1 vector as a fusion with the N-terminal of Mxe GyrA intein and chitin-binding domain (CBD) for simple purification. Expression was confirmed by western blot analysis. The fusion protein containing uricase-intein-CBD was purified on a chitin column. The cleavage was induced by adding DTT,1 as a reducing agent to release uricase. The purity of uricase and complete excision of the intein and CBD were confirmed by SDS-PAGE2 while its proper folding was proved by circular dichroism and fluorescent emission studies. Isoelectric focusing further confirmed its homogeneity when a single protein band was observed at the predicted pI value. This is the first report of successful purification of a multimeric therapeutic enzyme by intein-mediated protein cleaving using a well-established and facile system. PMID- 27702490 TI - Genome mining and motif truncation of glycoside hydrolase family 5 endo-beta-1,4 mannanase encoded by Aspergillus oryzae RIB40 for potential konjac flour hydrolysis or feed additive. AB - Two novel glycosyl hydrolase family 5 (GH5) beta-mannanases (AoMan5A and AoMan5B) were identified from Aspergillus oryzae RIB40 by genome mining. The AoMan5A contains a predicted family 1 carbohydrate binding module (CBM-1), located at its N-terminal. The AoMan5A, AoMan5B and truncated mutant AoMan5ADeltaCL (truncating the N-terminal CBM and linker of AoMan5A) were expressed retaining the N-terminus of the native protein in Pichia pastoris GS115 by pPIC9KM. The specific enzyme activity of the purified reAoMan5A, reAoMan5B and reAoMan5ADeltaCL towards locust bean gum at pH 3.6 and 40 degrees C for 10min, was 8.3, 104.2 and 15.8U/mg, respectively. The temperature properties of the reAoMan5ADeltaCL were improved by truncating CBM. They can degrade the pretreated konjac flour and produce prebiotics. In addition, they had excellent stability under simulative gastric fluid and simulative prilling process. All these properties make these recombinant beta-mannanases potential additives for use in the food and feed industries. PMID- 27702491 TI - Hyaluronic acid-supported combination of water insoluble immunostimulatory compounds for anti-cancer immunotherapy. AB - A novel powder-form combination adjuvant system containing two immunostimulatory compounds was firstly developed and evaluated as a therapeutic intervention for cancer immunotherapy. With the help of hyaluronic acid (HA), water insoluble monophosphoryl lipid A (MPL), QS21 and imiquimod (R837), could be easily dispersed in aqueous solution and lyophilized as powder-form, which have an advantage in room-temperature storage stability compared with those conventional liquid formulation that requires cold storage. Two kinds of HA-based combination vaccine adjuvants (HA/MPL/QS21, HMQ and HA/MPL/R837, HMR) contributed to the increase of both humoral and cellular immunity, which is very important for efficient cancer immunotherapy. Through the challenge experiments in EG7-OVA (mouse lymphoma-expressing OVA) tumor-bearing mice model, we found out that the immunostimulatory effects of HMQ and HMR were successful in the inhibition of tumor proliferation. Taken together, both HA-based powder-form combination adjuvant systems are expected to be used as potent prophylactic and therapeutic cancer vaccine. PMID- 27702492 TI - Hyaluronic acid conjugated micelles possessing CD44 targeting potential for gene delivery. AB - The high- and low-molecular weight hyaluronic acid (HHA and LHA) were used to conjugate with PLGA-PEG copolymers which were applied to encapsulate DOTAP/pDNA (D/P) lipoplex as a CD44-targeted micelle delivery system. The size and zeta potential of DNA loaded micelles were measured. The cytotoxicity and cellular transfection of DNA loaded micelles were performed in CD44-positive MDA-MB-231 and MCF-7 cancer cells and CD44-negative HepG2 cells. The endocytosis mechanism of micelles was investigated further. The DNA loaded HA-conjugated micelles possessed negative-charged character which prevented erythrocytes from agglutination. Both LHA-PEG-PLGA and HHA-PEG-PLGA micelles had comparable cellular viability in L929 normal cells. The cellular transfection of HHA-PEG PLGA micelles was much higher than of LHA-PEG-PLGA micelles in CD44-positive cells. The specific and strong binding of HHA to CD44-positive cells resulted in the cellular transfection of HHA-PEG-PLGA micelles in CD44-positive cells significantly higher than in CD44-negative cells. PMID- 27702493 TI - Effects of concurrent ball milling and octenyl succinylation on structure and physicochemical properties of starch. AB - This work concerns the effects of concurrent ball milling (BM) and octenyl succinic anhydride (OSA) modification on the starch microstructure and physicochemical properties (swelling, emulsifying, and rheological). Unlike normal OSA-modified starches, the BM/OSA-modified starch displayed new features such as reduced viscosity and rigidity but increased paste stability during shearing, heating and cooling, regardless of the substitution degree. More interestingly, while the physicochemical properties could be regulated by simply altering the BM treatment time, BM/OSA was more efficient and effective at modulating starch properties during the initial period (approx. 10h), as seen by the rapid evolutions in starch structural disruption and OSA esterification. Thus, the BM/OSA modification can serve as a viable and cost-effective approach for producing octenyl succinate starches where low viscosity (at relatively high concentrations) and high paste stability are desired. PMID- 27702494 TI - Effect of low and high methoxyl citrus pectin on the properties of polypyrrole based electroactive hydrogels. AB - Electroactive hydrogels were prepared using commercial citric pectin, either raw (PC) or purified through dialysis (dPC), and chemically synthesized polypyrrole (PPy). 1H NMR analyses showed that PC is a low methoxyl pectin (degree of methoxylation, DM=46%) and dPC is a high methoxyl pectin (DM=77%). The pyrrole polymerization was monitored through UV-vis spectroscopy and both samples were observed to be good stabilizers for PPy in aqueous medium. The dispersions were used to prepare the hydrogels h-PC-PPy and h-dPC-PPy. The hydrogel h-dPC-PPy has a higher swelling index (SI~25%) at pH 1.2 than the hydrogel h-PC-PPy (SI~7%). Contrastingly, at pH 6.8 both hydrogels lost their mechanical integrity. Raman spectroscopy revealed that PPy is more oxidized in h-PC-PPy. Nevertheless, both hydrogels are electroactive and therefore can be considered for applications in which the control of the degree of swelling is desired. PMID- 27702495 TI - Functionalization of chitosan by a free radical reaction: Characterization, antioxidant and antibacterial potential. AB - Chitosan was functionalized with epigallocatechin gallate (EGCG) by a free radical-induced grafting procedure, which was carried out by a redox pair (ascorbic acid/hydrogen peroxide) as the radical initiator. The successful preparation of EGCG grafted-chitosan was verified by spectroscopic (UV, FTIR and XPS) and thermal (DSC and TGA) analyses. The degree of grafting of phenolic compounds onto the chitosan was determined by the Folin-Ciocalteu procedure. Additionally, the biological activities (antioxidant and antibacterial) of pure EGCG, blank chitosan and EGCG grafted-chitosan were evaluated. The spectroscopic and thermal results indicate chitosan functionalization with EGCG; the EGCG content was 25.8mg/g of EGCG grafted-chitosan. The antibacterial activity of the EGCG grafted-chitosan was increased compared to pure EGCG or blank chitosan against S. aureus and Pseudomonas sp. (p<0.05). Additionally, EGCG grafted chitosan showed higher antioxidant activity than blank chitosan. These results indicate that EGCG grafted-chitosan might be useful in active food packaging. PMID- 27702496 TI - Tribology of swollen starch granule suspensions from maize and potato. AB - The tribological properties of suspensions of cooked swollen starch granules are characterised for systems based on maize starch and potato starch. These systems are known as granule 'ghosts' due to the release (and removal) of polymer from their structure during cooking. Maize starch ghosts are less swollen than potato starch ghosts, resulting in a higher packing concentration and greater mechanical stability. In a soft-tribological contact, maize ghost suspensions reduce friction compared to the solvent (water), generate bell-shaped tribological profiles characteristic of particle entrainment and show a marked concentration dependence, whereas potato ghost suspensions exhibit lubrication behaviour similar to water. Microscopy analysis of the samples following tribological testing suggests that this is due to the rapid break-up of potato ghosts under the shear and rolling conditions within the tribological contact. A reduction in the small deformation moduli (associated with a weak gel structure) is also observed when the potato ghost suspensions are subjected to steady shear using parallel plate rheometry; both microscopy and particle size analysis show that this is accompanied by the partial shear-induced breakage of ghost particles. This interplay between particle microstructure and the resultant rheological and lubrication dynamics of starch ghost suspensions contributes to an enhanced mechanistic understanding of textural and other functional properties of cooked starches in food and other applications. PMID- 27702497 TI - Small-angle X-ray and light scattering analysis of multi-layered Curdlan gels prepared by a diffusion method. AB - Curdlan, a microbial polysaccharide, forms a multi-layered gel consisting of four layers with different turbidity when its alkaline solution is dialyzed against aqueous solutions containing Ca2+ (diffusion-set gel). The present study clarified the microstructure of each layer of the diffusion-set Curdlan gel by small-angle X-ray scattering (SAXS) and small-angle light scattering (SALS). The SAXS data showed that Curdlan chains assume a helical ordered conformation in the gel and that the gel consists of the fibrils formed by the association of Curdlan chains and the aggregates of fibrils. The SAXS results also indicated that the gelation is induced by the formation of a network of Ca2+-cross-linked fibrils in the outer region of the gel, whereas by the network formation of the aggregation of fibrils in the neutralization process in the inner region of the gel. A structural anisotropy of the gel was investigated by analysis of two-dimensional SAXS images, showing that the fibril is oriented circumferentially in the outer region of the cylindrical gel, whereas it is oriented randomly in the inner region of the gel. The SALS data showed that a characteristic length of an inhomogeneous structure in the turbid layers is of the order of micrometers. The observed spatial variation of the microscopic structure is caused by the difference in the paths of pH and [Ca2+] traced in the gelation process. PMID- 27702498 TI - Silk fibroin organization induced by chitosan in layer-by-layer films: Application as a matrix in a biosensor. AB - In this paper, we show that chitosan may induce conformation changes in silk fibroin (SF) in layer-by-layer (LbL) films, which were used as matrix for immobilization of the enzyme phytase to detect phytic acid. Three chitosan (CH) samples possessing distinct molecular weights were used to build CH/SF LbL films, and a larger change in conformation from random coils to beta-sheets for SF was observed for high molecular weight chitosan (CHH). The CHH/SF LbL films deposited onto interdigitated gold electrodes were coated with a layer of phytase, with which phytic acid could be detected down to 10-9M using impedance spectroscopy as the principle of detection and treating the data with a multidimensional projection technique. This high sensitivity may be ascribed to the suitability of the CHH/SF matrix, thus indicating that the molecular-level interactions between chitosan and SF may be exploited in other biosensors and biodevices. PMID- 27702499 TI - In situ functionalized nanobiocomposites dressings of bamboo cellulose nanocrystals and silver nanoparticles for accelerated wound healing. AB - An innovative approach was adopted where in situ synthesized silver nanoparticles (AgNPs) from leaf extract mediated reduction of AgNO3 were simultaneously impregnated into the matrix of cellulose nanocrystals (CNCs) isolated from Dendrocalamus hamiltonii and Bambusa bambos leaves, for formation of nanobiocomposites (NCs) in film and ointment forms. Here, use of plant CNCs was chosen as an alternate to bacterial cellulose for wound dressings. NCs possessing water absorption capacity and strong antibacterial activity showed synergistic effect on in vivo skin wound healing and documented faster and significant wound closure in treated mice. NCs exhibited lesser inflammation and early vasculogenesis at day 3 coupled with increased fibroblasts and collagen content at day 8 leading to faster neo-epithelization by day 14. Highly effective, biocompatible, and easy to apply NCs wound dressings (ointment and films) containing low amounts of Ag (0.05+/-0.01wt%) are potential candidates for effective skin repair. PMID- 27702500 TI - Effect of compression combined with steam treatment on the porosity, chemical compositon and cellulose crystalline structure of wood cell walls. AB - The changes of porosity, chemical composition and cellulose crystalline structure of Spruce (Picea abies Karst.) wood cell walls due to compression combined with steam treatment (CS-treatment) were investigated by nitrogen adsorption, confocal Raman microscopy (CRM) and X-ray diffraction (XRD), respectively. A number of slit-shaped mesopores with a diameter of 3.7nm was formed for the CS-treated wood, and more mesopores were found in the steam-treated wood. CRM results revealed cellulose structure was affected by treatment and beta-aryl-ether links associated to guaiacyl units of lignin was depolymerized followed by re condensation reactions. The crystallinity index (CrI) and crystallite thickness (D200) of cellulose for CS-treated wood were largely increased due to crystallization in the semicrystalline region. Higher degree of increase in both CrI and D200 was observed in both the earlywood and latewood of steam-treated wood, ascribing to the greater amount of mesopores in steam-treated wood than CS treated wood. PMID- 27702501 TI - Hydroxypropyl methylcellulose based aerogels: Synthesis, characterization and application as adsorbents for wastewater pollutants. AB - Hydroxypropyl methylcellulose (HPMC) E4M and J5MS samples with degrees of substitution of methyl groups (DS) 1.9 and 1.5, respectively, and molar substitutions of hydroxypropyl groups (MS) 0.25 and 0.75, respectively, were used to create aerogels in the presence of citric (cit), oxalic (oxa) or terephthalic (ter) acids, as crosslinkers. E4M-cit, J5MS-cit and J5MS-oxa aerogels presented outstanding stability in water, acid media, alcohols, acetone and hydrocarbons, density values of~(0.020+/-0.002)g/cm3, compressive modulus ranging from (111+/ 9)kPa to (133+/-11)kPa. On the other hand, E4M-oxa, E4M-ter and J5MS-ter aerogels were not adequate adsorbents because they collapsed in water. The adsorption behavior of 17alpha-ethinyl estradiol (EE) and methylene blue (MB) onto E4M-cit, J5MS-cit and J5MS-oxa aerogels were fitted to Freundlich model, indicating higher affinity of EE for J5MS-cit and J5MS-oxa and higher affinity of MB for E4M-cit aerogels. HPMC aeorogels could be successfully reused. PMID- 27702502 TI - In vitro release of metformin hydrochloride from sodium alginate/polyvinyl alcohol hydrogels. AB - Hydrogels, based on polysaccharides have found a number of applications as drug delivery carriers. In this work, hydrogels of full characterized sodium alginate (Mn 87,400g/mol) and commercial poly(vinyl alcohol) (PVA) sensitive to pH and temperature stimuli were obtained using a simple, controlled, green, low cost method based on freeze-thaw cycles. Stable hydrogels of sodium alginate/PVA with 0.5:1.5 and 1.0:1.0w/v concentrations showed very good swelling ratio values in distilled water (14 and 20g/g, respectively). Encapsulation and release of metformin hydrochloride in hydrogels of 1.0:1.0w/v sodium alginate/PVA was followed by UV spectroscopy. The hydrogel released a very low amount of metformin hydrochloride at pH 1.2; the highest release value (55%) was obtained after 6h at pH 8.0. Also, the release of metformin hydrochloride was studied by 1H NMR spectroscopy, the temporal evolution of methyl group signals of metformin showed 30% of drug release after 3h. PMID- 27702503 TI - Carbon disulfide-modified magnetic ion-imprinted chitosan-Fe(III): A novel adsorbent for simultaneous removal of tetracycline and cadmium. AB - A novel composite of carbon disulfide-modified magnetic ion-imprinted chitosan Fe(III), i.e., MMIC-Fe(III) composite, was prepared as an efficient adsorbent for the simultaneous removal of tetracycline (TC) and Cd(II). This adsorbent showed excellent performance in removing TC and Cd(II) due to its rapid kinetics, high adsorption capacity, good reusability, and was well suited for use with real water samples. Kinetics studies demonstrated that the adsorption proceeded according to a pseudo-second order model. The adsorption isotherms were well described by the Langmuir model, with maximum adsorption capacity for TC and Cd(II) being 516.29 and 194.31mg/g, respectively. The synergistic effect of TC and Cd(II) adsorption might be due to the formation of TC-Cd(II) complex bridging the adsorbate and adsorbent. These properties demonstrate the potential application of MMIC-Fe(III) for the simultaneous removal of TC and Cd(II), and may provide some information for the synergistic removal of antibiotics and heavy metals from aquatic environments. PMID- 27702504 TI - Integration of lysozyme into chitosan nanoparticles for improving antibacterial activity. AB - Lysozyme was integrated into chitosan nanoparticles (CS-NPs) to improve the antibacterial activity. CS-NPs and chitosan-lysozyme nanoparticles (CS-Lys-NPs) were prepared according to the ionic gelation technique and then characterized by average size, zeta potential, polydispersity index (PDI), atomic force microscopy (AFM), fourier transform infrared (FT-IR), small-angle X-ray scattering (SAXS), circular dichroism (CD) and UV-visible spectroscopy. Antibacterial properties were investigated by transmission electron microscopy (TEM) based on observation of the inhibition zone and measurement of the minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC) of CS-NPs and CS-Lys-NPs against E. coli and B. subtilis. The CS-NPs had particle sizes of 476.2-548.1nm, while an increase to ~488.8 to 613.5nm was observed upon loading with lysozyme. The results suggested that the integration of lysozyme into CS-NPs enhanced the antibacterial activity against E. coli and B. subtilis, which may show great potential for use in the food industry and other applications in the form of direct addition or incorporation into packaging. PMID- 27702505 TI - Preparation of chemically modified canola protein isolate with gum Arabic by means of Maillard reaction under wet-heating conditions. AB - The aim of this study was to produce covalently attached conjugate between canola protein isolate (CPI) and gum Arabic (GA) in aqueous solutions via the Maillard reaction at 90 degrees C in a model system consisting of 2% CPI and 1, 2 or 4% GA. Upon decreasing of free amino group content in the glycosylated CPI to 72%, a new band near the loading end of sodium dodecyl sulfate-polyacrylamide gel electrophoresis and a shift of CPI peak in high performance size exclusion chromatography confirmed that the covalent attachment of CPI to GA was successful. The results of secondary structure analysis suggested that grafted CPI had decreased alpha-helix and beta-sheet levels and increased random coils level. The solubility of CPI at isoelectric point was improved remarkably after grafting with GA. The optimal conjugation conditions chosen from the further experiments were 1% of GA, 90 degrees C and reaction time 15min. PMID- 27702506 TI - A novel pH-induced thermosensitive hydrogel composed of carboxymethyl chitosan and poloxamer cross-linked by glutaraldehyde for ophthalmic drug delivery. AB - In this work, a stimuli-responsive three dimensional cross-linked hydrogel system containing carboxymethyl chitosan (CMC) and poloxamer composed of a poly (ethylene oxide)/poly (propylene oxide)/poly (ethylene oxide) (PEO-PPO-PEO) block copolymer was constructed, and its aqueous solution was found to undergo a reversible sol-gel transition upon a temperature and/or pH change at a very low concentration. The hydrogels were synthesized via a cross-linking reaction using glutaraldehyde (GA) as the cross-linking agent. The structures of the hydrogels were characterized by FTIR, XRD, NMR and SEM studies and the swelling behaviour was studied in different buffered solutions. The results obtained indicated that cross-linked F127-CMC underwent discontinuous phase transition in different temperature and pH solutions. The hydrogels at 35 degrees C and pH 7.4 were found to have larger pores than at the other three conditions which resulted in greater swelling. The result of rheological studies showed that the gelation temperature was 32-33 degrees C and the viscosity of the hydrogel increased quickly after gelation. In an addition, the cytotoxicity and in vitro release was studied at different pH values and temperature. The results of a CCK-8 (Cell Counting Kit-8) assay showed that the hydrogel and its physical mixture solution were not cytotoxic to human corneal epithelial cells at a low concentration. Using the drug nepafenac (NP) as a model drug, the controlled drug release behaviour of these hydrogels was investigated. Owing to the formation of F127-CMC/NP retarding the diffusion rate of NP, a sustained release of NP from the hydrogel can be obtained. The release rate was found to be maximum at 35 degrees C and pH 7.4. From these preliminary evaluations, it is possible to conclude that the hydrogels have an excellent potential for application in ophthalmic drug delivery systems.

AB - In the current study, dextran (DEX) was covalently conjugated to the surface of nano-GO sheets, making stable biocompatible dextran coated GO (GO-DEX). The prepared GO-DEX was nontoxic to 4T1 mammary carcinoma cell line at concentrations up to 300MUg/mL. AS1411 aptamer, a ssDNA aptamer which can improve the intracellular uptake by nucleolin recognition, also has been introduced to hydroxyl groups of DEX in GO-DEX to produce GO-DEX-Apt. Moreover, curcumin (CUR), a natural polyphenol, found in the rhizomes of Curcuma longa (turmeric) which shows antineoplastic effects, was loaded onto the GO-DEX and GO-DEX-Apt via pi-pi stacking interactions with a high loading capacity (~29wt%). The GO-DEX-Apt-CUR could efficiently enter into 4T1 and MCF-7 nucleolin over-expressed cancer cells confirmed by fluorescence microscope and flowcytometry, and it also showed significantly higher cytotoxicity. These types of targeted nanoscale drug delivery vehicles on the basis of DEX coated GO may find potential application in cancer chemotherapy. PMID- 27702508 TI - Miscanthus Giganteus: A commercially viable sustainable source of cellulose nanocrystals. AB - With a goal of identifying a new scalable source for cellulose nanocrystals (CNCs), we successfully isolated CNCs from a sustainable, non-invasive grass, Miscanthus x. Giganteus (MxG). Subjecting MxG stalks to base hydrolysis, bleaching and acid hydrolysis allowed access to cellulose nanocrystals (MxG-CNC) in high yields. X-ray diffraction studies showed the crystallinity of the MxG CNCs increased with subsequent treatment conditions (>90% after HCl hydrolysis). Transmission electron microscopy showed that the MxG-CNC exhibit relatively high aspect ratios (60-70), and small angle neutron scattering showed the crystals were ribbon-like with a width and thickness of 8.5 and 2.8nm respectively. As expected, thermomechanical analysis of nanocomposites fabricated with carboxylic acid functionalized MxG-CNC (MxG-CNC-COOH) and PVAc showed an increase in modulus (above Tg) as filler content was increased. Comparing the properties to PVAc nanocomposites containing CNCs from wood showed at least as good, if not slightly better, reinforcement at the same loading level.

AB - Salecan is a novel water-soluble extracellular beta-glucan and possesses excellent physicochemical and biological properties. Here, redox/pH dual stimuli responsive hydrogel based on Salecan grafted with itaconic acid (IA) and 2 hydroxyethyl methacrylate (HEMA) were prepared using disulfide-functionalized crosslinker N,N-bis(acryloyl)cystamine (BAC) for controlled drug delivery. The introduction of carboxylic groups endows the system with pH-sensitive character, swelling behavior of the hydrogel was conducted by changing the pH and Salecan content. It was demonstrated that DOX was efficiently loaded into the hydrogels and released in a controlled fashion via pH-control and swelling-shrinking mechanism. More importantly, DOX-loaded hydrogels showed dose dependent cytotoxicity toward A549 cell, and efficient cell killing was observed. Furthermore, a key point of this study was that the presence of disulfide linkage in system favored the degradation of hydrogels in the reductive environment. These results highlight the potential of Salecan-g-SS-poly(IA-co-HEMA) hydrogel as a novel system for the controlled release of anti-cancer drugs. PMID- 27702510 TI - The core structure of a Dendrobium huoshanense polysaccharide required for the inhibition of human lens epithelial cell apoptosis. AB - The aim of this work was to investigate the core structure of a Dendrobium huoshanense polysaccharide DHPD1 required for the inhibition of lens epithelial cell apoptosis. In order to obtain the fragments containing the core domain, pectinase was employed to hydrolyze DHPD1. After 24h reaction, it is interesting that the hydrolyzation seemed to be stopped, leading to a final enzymatic fragment DHPD1-24 with molecular weight about 1552Da. Compared to DHPD1, although the bioactivity is decreased, DHPD1-24 remained the ability to inhibit the H2O2 induced apoptosis of human lens epithelial (HLE) cells via suppressing the MAPK signaling pathways. These results suggested that DHPD1-24 might be the core domain required for DHPD1 to inhibit HLE cell apoptosis. Methylation analysis showed DHPD1-24 was composed of (1->5)-linked-Araf, (1->3,6)-linked-Manp, 1 linked-Glcp, (1->4)-linked-Glcp, (1->6)-linked-Glcp, (1->4,6)-linked-Glcp, (1->6) linked-Galp and 1-linked-Xylp in a molar ratio of 1.06:1.53:2.11:2.04:0.93:0.91:0.36:1.01. Moreover, the primary structural features of DHPD1-24 were characterized by NMR spectrum. PMID- 27702512 TI - Relationships between protein content, starch molecular structure and grain size in barley. AB - Correlations among barley protein, starch molecular structure and grain size were determined using 30 barley samples with variable protein contents. Starch molecular structure was characterized by fluorophore-assisted carbohydrate electrophoresis and by size-exclusion chromatography (SEC, also termed GPC). The chain-length distributions of amylopectin were fitted using a mathematical model reflecting the relative activities of starch branching enzymes and starch synthase enzymes. Increased protein content significantly and negatively correlated with higher amounts of amylose with longer chains (degree of polymerization, DP 1600-40000) while barley grain sizes positively associated with starch contents. Protein content also positively correlated with the proportion of longer chains of amylopectin (DP 34-100). These results showed that the enzyme activities of starch synthases change with protein content, leading to altered starch contents, structures and grain sizes. From this perspective, selecting for large grain size (or low protein content) does not necessarily relate to starch structure, although may suggest long chains of amylopectin. Measuring starch structure could give a good indication of process performance in human food, animal feed and brewing, as all these structural features contribute to significant functional properties. PMID- 27702511 TI - Fractionation, preliminary structural characterization and bioactivities of polysaccharides from Sargassum pallidum. AB - Sargassum pallidum polysaccharides were fractioned using a DEAE-Sepharose fast flow column and four polysaccharide fractions (SP-P1, SP-P2, PV-P3 and SP-P4) were obtained. Structural analyses indicated that SP-P2 and SP-P4 had higher molecular weights than SP-P1 and SP-P3. SP-P2, SP-P3 and SP-P4 comprised of fucose, rhamnose, arabinose, galactose, glucose, xylose, and mannose in a similar molar ratio, while SP-P1 did not contain arabinose. SP-P2 and SP-P4 had a similar number of (1->6) or (1->) glycosidic linkages (1->2) or (1->4) glycosidic linkages and (1->3) glycosidic linkages, while SP-P1 and SP-P3 contained a small number of (1->3) glycosidic linkages. SP-P2 exhibited better bioactivities than SP-P1, SP-P3 and SP-P4, including antioxidant, anti-hemolysis inhibitory, alpha amylase and alpha-glucosidase inhibitory and antiproliferative activities. These data suggest that S. pallidum has four polysaccharide fractions with different structural features and bioactivities and SP-P2 has potential to be explored as a functional food or complementary medicine. PMID- 27702513 TI - Novel reverse osmosis membranes composed of modified PVA/Gum Arabic conjugates: Biofouling mitigation and chlorine resistance enhancement. AB - A novel crosslinked Poly (vinyl alcohol) (PVA) reverse osmosis (RO) thin film membrane conjugated with Gum Arabic (GA) with superb performance and features was synthesized for water desalination. RO membrane desalination parameters, such as hydrophilicity, surface roughness, water permeability, salt rejection, Chlorine resistance and biofouling resistance were evaluated using a dead end RO filtration unit. The incorporation of Pluronic F127 and the conjugation of Gum Arabic improved the overall RO performance of the membranes. This study has shown that the membrane PVA-GA-5 that contains 0.9wt% Gum Arabic provided excellent permeation, salt rejection, Chlorine and biofouling resistance and mechanical strength. The most remarkable result to arise from this research is that the overall RO performance enhancement has been achieved while utilizing PVA/Gum Arabic as a separation layer without the use of a substrate, which eliminates negative effects associated with the use of a substrate like internal concentration polarization. PMID- 27702514 TI - Alyssum homolocarpum seed gum-polyvinyl alcohol biodegradable composite film: Physicochemical, mechanical, thermal and barrier properties. AB - Films made from Alyssum homolocarpum seeds gum (AHSG) have poor mechanical and barrier (to oxygen) properties. In the present study poly vinyl alcohol (PVA) was used to improve the physicochemical properties of AHSG films. Results indicated that the addition of PVA significantly increased the moisture content, solubility, elongation at break (EB) and transparency while it decreased the density, oxygen permeability, chroma, water contact angle and Young modulus of AHSG based films. Films with higher AHSG to PVA ratios had lower water vapor permeability (WVP). The light barrier measurements presented low values of transparency at 600nm for PVA/AHSG films, indicating that films were very transparent while they had excellent barrier properties against UV light. Results for FTIR, DSC and SEM showed a clear interaction between PVA and AHSG, forming a new material. These results indicated that PVA/AHSG blend films had good compatibility. PMID- 27702515 TI - Novel hydrophobic cotton fibers adsorbent for the removal of nitrobenzene in aqueous solution. AB - In order to improve the superhydrophobic and oil-wet properties of raw cotton fibers come from Jiangsu province, China. A novel adsorbent, hydrophobic cotton fibers (HCF) with an excellent superhydrophobic and larger length was synthesized via modified sol-gel method and examined for the removal of nitrobenzene in aqueous solution. Results show that the treated raw cotton fibers exhibited outstanding non-wettability with the WCA of 152 degrees and the larger length of 0.2-0.4cm, which offers an opportunity to separation in for the removal of nitrobenzene. It was found that adsorption isotherm and kinetics of nitrobenzene onto HCF were well described by the Freundlich and pseudo-second-order kinetic models, respectively. The thermodynamic data showed that the nitrobenzene adsorption onto HCF was a spontaneous, endothermic and physisorption reaction. The monolayer adsorption capacity of nitrobenzene was found to be 16.85mg/g at 30 degrees C. PMID- 27702516 TI - Radiation grafting of N-vinylcaprolactam onto nano and macrogels of chitosan: Synthesis and characterization. AB - The aim of this study was to synthesize chitosan hydrogels, in macro- and nano size, grafted with N-vinylcaprolactam (NVCL) using gamma radiation, and evaluate their potential application as a drug delivery system, using 5-fluorouracil (5 FU) as a model drug. The effect of dose and monomer concentration in the grafting process was studied, and the materials were characterized by FTIR, TGA, DLS, SEM and AFM. Higher grafting percentages were observed for the nanogels system. Although both the grafted macro- and nanogels, (net-CS)-g-NVCL, showed a response to pH (4.75) and temperature (31-33 degrees C), the nanogels showed a better swelling response to both stimuli because of their higher surface area. Both systems were able to load 5-FU in small amounts (2-3.5mgg-1) and the release was sustained for more than 12h, showing that the modified macro and nanogels can be a potential alternative for the administration of drugs. PMID- 27702517 TI - The heparin-like activities of negatively charged derivatives of low-molecular weight polymannuronate and polyguluronate. AB - A series of low-molecular-weight polymannuronate (LPM) and polyguluronate (LPG) polyanionic derivatives, including LPM/LPG phosphate (LPMP/LPGP), LPM/LPG H phosphonate (LPMHP/LPGHP) and LPM/LPG sulfate (LPMS/LPGS), were prepared as heparinoids by chemical modification of LPM and LPG. The structures and characteristics of LPM, LPG and their derivatives were elucidated based on high performance gel permeation chromatography (HPGPC), fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (NMR) and polyacrylamide gel electrophoresis (PAGE). In order to test the heparin-like activities of these derivatives and to reveal the activities affected by substituent groups and PM/PG polysaccharide backbones, the anticoagulant activities and FGF/FGFR1c signaling activation abilities were evaluated in vitro. The results showed that sulfate group was the best substituent group to improve the heparin-like activities of LPM/LPG compared with the other two anionic groups. The results also showed that sulfated derivative based on PG structure had better activities than that based on PM structure. PMID- 27702518 TI - Synthesis, characterization, and antimicrobial activities of sulfonated chitosan. AB - Sulfonated chitosan (SCS) was prepared via a facile chemical procedure by using 1,3-propane sultone attached to the backbone of chitosan. The resulting chitosan derivative was characterized by Fourier transform-infrared spectroscopy, nuclear magnetic resonance spectroscopy, gel permeation chromatography, elemental analysis, and thermo gravimetric analysis. The antibacterial experiments demonstrated that SCS exhibited higher antibacterial activities against Escherichia coli and Staphylococcus aureus with the minimum inhibitory concentration (MIC) of 0.13mg/mL and 2.00mg/mL than those of water-soluble chitosan (WCS) with MIC of 0.50mg/mL and 4.00mg/mL. However, different antifungal activities of SCS against Arthrinium sacchari (MIC, 64.00mg/mL) and Botrytis cinerea (MIC, 0.25mg/mL) were observed. Scanning electron microscopy revealed that WCS and SCS could damage and deform the structure of fungal hyphae with different action modes. It is worth mentioning that SCS exhibited selective antifungal activity, which was an important parameter to control its biological performance in many fields. PMID- 27702519 TI - An improved pH-responsive carrier based on EDTA-Ca-alginate for oral delivery of Lactobacillus rhamnosus ATCC 53103. AB - A pH-responsive carrier based on an ethylenediaminetetraacetic-calcium-alginate (EDTA-Ca-Alg) system was developed by controlling the release of Ca2+. The system remained in the solution state at neutral pH since EDTA completely chelated the Ca2+. In contrast, a hydrogel immediately formed when the pH was below 4.0, which triggered the in situ release of Ca2+ from the EDTA-Ca compound and led to alginate-Ca binding. Taking advantage of the pH sensitivity, we prepared hydrogel microspheres with uniform size to entrap Lactobacillus rhamnosus ATCC 53103 through emulsification. In an acidic environment, the hydrogel structure remained compact with negligible pores to protect L. rhamnosus ATCC 53103. However, in a neutral intestinal environment, the hydrogel structure gradually disassembled because of the Ca2+ release from the hydrogel, which caused cell release. Therefore, a pH-responsive carrier was developed for the protection and the controlled release of cells in gastrointestinal tract, thus providing potential for oral delivery of probiotics. PMID- 27702520 TI - Interface modified polylactic acid/starch/poly epsilon-caprolactone antibacterial nanocomposite blends for medical applications. AB - In this study, an optimized interface-modified ternary blend with antibacterial activity based on polylactic acid/starch/poly epsilon-caprolactone (PLASCL20), mixed with nano hydroxyapatite (nHA) via melt blending. This method results in a homogeneous nanocomposite blend in which the addition of 3% nHA improves the overall properties such as hydrolytic degradation, hydrophilicity, antibacterial activity and the drug release comparing to PLASCL20. Moreover, the simultaneous use of nHA and encapsulated triclosan (LATC30) compensated the negative effect of triclosan through increasing the possible cell attachment. According to the contact angle results, nHA was thermodynamically driven into the interface of PLA and PCL/Starch phases. The addition of 3% nHA showed a good adjustment between the hydrolytic degradation and the release profile, therefore, their electrospun microfibers demonstrated an improved fibroblast (L929) cell attachment. The aforementioned nanocomposite blend is a suitable antibacterial candidate for many medical applications with minimum side effects due to the controlled release of triclosan. PMID- 27702521 TI - High performance agar/graphene oxide composite aerogel for methylene blue removal. AB - A novel three-dimensional (3D) agar/graphene oxide (AGO) composite aerogel was prepared by a vacuum freeze drying method. The AGO aerogel was tested for its adsorption capacity of methylene blue (MB) and was found to have a maximum adsorption capacity of 578mg/g, as determined from the Langmuir isotherm. The adsorption kinetic studies revealed that adsorption followed pseudo-second-order model. The thermodynamic parameters calculated from the Van't Hoff equation indicate that the adsorption was an endothermic and spontaneous process. The adsorption mechanism may be attributed to electrostatic interaction between MB and AGO aerogel. Furthermore, the AGO aerogel can easily be recycled with a dilute NaOH solution wash, retaining over 91% of the adsorption capacity after recycling three times. PMID- 27702523 TI - The effect of ionotropic gelation residence time on alginate cross-linking and properties. AB - The ability to engineer biocompatible polymers with controllable properties is highly desirable. One such approach is to cross-link carbohydrate polymers using ionotropic gelation (IG). Previous studies have investigated the effect of curing time on alginate cross-linking. Herein, we discuss a novel study detailing the effect of IG residence time (IGRT) on the cross-linking of alginate with calcium ions (Ca2+) along with water migration (syneresis) and their subsequent impact on the pharmaceutical properties of alginate particles. IGRT was shown to have a significant effect on particle size, porosity, density, mechanical strength and swelling of calcium alginate particles as well as drug release mechanism. Furthermore, we describe a novel application of electron dispersive spectroscopy (EDS), in conjunction with Fourier Transform- infra red (FT-IR) spectroscopy, to analyze and monitor the changes in Ca2+ concentration during cross-linking. A simple procedure to determine the concentration and distribution of the surface and internal Ca2+ involved in alginate cross-linking was successfully developed.

AB - A water-soluble polysaccharide from Artocarpus heterophyllus Lam. (jackfruit) pulp (JFP-Ps) was purified and its physicochemical properties were investigated. The in vitro antioxidant activities of JFP-Ps was evaluated by measuring DPPH and OH radicals scavenging activities, as well as reducing power. The results showed that JFP-Ps contained 79.12% of total sugar, 5.83% of protein, 15.65% of uronic acid, and 15 kinds of amino acids with high levels of Asp, Glu, Val, Leu and Lys. JFP-Ps was mainly composed of Rha, Ara, Gal, Glc, Xyl and GalA, with an average molecular weight of 1668kDa. FT-IR results showed the bands at the range of 1200 850cm-1 suggested the presence of carbohydrates in JFP-Ps. The results of antioxidant activities showed that JFP-Ps exhibited strong DPPH and OH radical scavenging activities, with a relatively lower reducing power, suggesting that JFP-Ps can be exploited as effective natural antioxidant applications in medical and food industries. PMID- 27702524 TI - Bio-inspired production of chitosan/chitin films from liquid crystalline suspensions. AB - Inspired by chitin based hierarchical structures observed in arthropods exoskeleton, this work reports the capturing of chitin nanowhiskers' chiral nematic order into a chitosan matrix. For this purpose, highly crystalline chitin nanowhiskers (CTNW) with spindle-like morphology and average aspect ratio of 24.9 were produced by acid hydrolysis of chitin. CTNW were uniformly dispersed at different concentrations in aqueous suspensions. The suspensions liquid crystalline phase domain was determined by rheological measurements and polarized optical microscopy (POM). Chitosan (CS) was added to the CTNW isotropic, biphasic and anisotropic suspensions and the solvent was evaporated to allow films formation. The Films' morphologies as well as the mechanical properties were explored. A correlation between experimental results and a theoretical model, for layered matrix' structures with fibers acting as a reinforcement agent, was established. The results evidence the existence of two different layered structures, one formed by chitosan layers induced by the presence of chitin and another formed by chitin nanowhiskers layers. By playing on the ratio chitin/chitosan one layered structure or the other can be obtained allowing the tunning of materials' mechanical properties. PMID- 27702525 TI - Preparation and characterization of agar-based nanocomposite films reinforced with bimetallic (Ag-Cu) alloy nanoparticles. AB - Agar-based active nanocomposite films were prepared by incorporating silver copper (Ag-Cu) alloy nanoparticles (NPs) (0.5-4wt%) into glycerol plasticized agar solution. Thermo-mechanical, morphological, structural, and optical properties of the nanocomposite films were characterized by texture analyzer, differential scanning calorimetry (DSC), scanning electron microscope (SEM), X ray diffraction (XRD), Fourier transforms infrared (FTIR) spectroscopy, and surface color measurement. Tensile strength and the melting temperature of the film increased linearly with NPs loading concentration. Color, transparency and UV barrier properties of agar films were influenced by the reinforcement of Ag-Cu NPs. XRD analysis confirmed the crystalline structure of the Agar/Ag-Cu nanocomposite films, whereas the smoothness and the homogeneity of film surface strongly reduced as observed through the SEM. The nanocomposite films exhibited a profound antibacterial activity against both Gram-positive (Listeria monocytogenes) and Gram-negative (Salmonella enterica sv typhimurium) bacteria. Overall, the agar nanocomposite films could be used as packaging material for food preservation by controlling foodborne pathogens and spoilage bacteria. PMID- 27702527 TI - Sodium alginate-assisted exfoliation of MoS2 and its reinforcement in polymer nanocomposites. AB - In this work, molybdenum disulfide (MoS2) nanosheets were facilely prepared by direct exfoliation of MoS2 in aqueous media with the assistance of sodium alginate (SA). Transmission electron microscopy (TEM), X-ray diffraction (XRD) and Raman spectra results showed that the raw MoS2 was successfully exfoliated into few-layer MoS2 nanosheets (SA-MoS2). FTIR and thermal gravimetric analysis (TGA) investigations showed that the obtained MoS2 nanosheets were modified by SA after exfoliation and improved dispersion in water were achieved. The obtained SA MoS2 nanosheets were employed to reinforce the water-soluble polymer SA. No obvious macroscopic phase separation could be found from the SA/SA-MoS2 films. Dynamic mechanical analysis (DMA) results showed that almost 9 times enhancement for the storage modulus of SA was achieved with the incorporation of only 0.5wt% of SA-MoS2, and the thermal stability of SA was also found improved with the addition of SA-MoS2 according to the thermal gravimetric analysis TGA results. PMID- 27702526 TI - Palm olein-in-water Pickering emulsion stabilized by Fe3O4-cellulose nanocrystal nanocomposites and their responses to pH. AB - We studied the formation of palm olein-in-water (O/W) Pickering emulsion stabilized by Fe3O4-cellulose nanocrystals (MCNC) nanocomposites obtained by ultrasound assisted in-situ co-precipitation method. The synthesized MCNC nanocomposites successfully stabilized Pickering emulsion with dual responses. The magnetic tests revealed a direct-relation between attractability of MCNC stabilized Pickering emulsions and the emulsion droplet diameter. The Pickering emulsions were stable under pH ranging from 3 to 6. The stability substantially reduced around pH 8-10, and regained slowly when approaching pH 13. From microscopic and mastersizer analysis, monodisperse emulsion droplets were noticed at pH 3-6, and 13, while polydisperse emulsion were obtained at pH 8-12. The Pickering emulsions prepared at pH 6 are stable up to 14 days, while Pickering emulsions at pH 8 experienced coalescence. In this study, the dual stimuli responsive Pickering emulsion stabilized by MCNC may hold potentials for biomedical and drug delivery as new generation of smart nanotherapeutic carrier. PMID- 27702528 TI - In vitro antioxidant activities of an exopolysaccharide from a salt pan bacterium Halolactibacillus miurensis. AB - Exopolysaccharide (EPS) designated as HMEPS was isolated from Halolactibacillus miurensis and purified through gel filtration chromatography. EPS extracted from the supernatant yielded a 56.1% total carbohydrate content. The ash and moisture content were 12.1% and 1.5% respectively. Galactose and glucose were found as main monosaccharides of the HMEPS through HPLC analysis. FT-IR spectra of the HMEPS revealed its composition with hydroxyl, alkenes, amide and carboxyl as functional groups and aliphatic amine and alkynes at the fingerprint region. In vitro antioxidant activity was investigated against hydroxyl, DPPH, superoxide free radicals and the scavenging activity against all were found to be dose dependent proportionately. HMEPS showed higher reducing ability against superoxide radical and potency in chelating the ferrous ions. 10mg/ml of HMEPS was found equivalent to 2.7units of ascorbic acid through the total antioxidant assay. Phylogenetic relation of H. miurensis SEEN MKU3 (GenBank number KT803852) was plotted with MEGA 5.0. PMID- 27702529 TI - Cisplatin-crosslinked glutathione-sensitive micelles loaded with doxorubicin for combination and targeted therapy of tumors. AB - The delivery of combination chemotherapy by nanoscale platforms has been demonstrated to enhance cancer treatment in the clinic. Cisplatin (CDDP) crosslinked, glutathione-sensitive, tumor-targeting micelles based on carboxymethyl chitosan were designed for synergistic cisplatin-doxorubicin (DOX) combination chemotherapy. In our study, DOX was conjugated to carboxymethyl chitosan through a disulfide bond, which was structurally characterized by 1H NMR. The micelles formed by self-assembly were spherical, with the mean diameter of 274nm. The in vitro release studies revealed that the micelles were highly glutathione-sensitive. Cytotoxicity analysis demonstrated that the cisplatin crosslinked micelles loaded with DOX exhibited enhanced therapeutic efficacy compared with the DOX-loaded nanoparticles, free DOX, and free CDDP. Cellular uptake and intracellular release revealed that the cisplatin-crosslinked micelles loaded with DOX could efficiently deliver and release DOX into the cancer cells. These results clearly indicate that tumor-targeting and glutathione-sensitive micelles provide means for combination drug delivery in cancer treatment. PMID- 27702530 TI - Synthesis and thermal properties of paramylon mixed esters and optical, mechanical, and crystal properties of their hot-pressed films. AB - Acylation of paramylon, a storage polysaccharide of Euglena gracilis, using multiple acid anhydrides yielded thermoplastic paramylon mixed esters without significant depolymerization. DSC examination showed that the shorter the acyl chain, the higher both the melting and glass transition temperature of the ester. TG analyses revealed their higher thermostability with the 5% weight loss temperature of ~330 degrees C. Melt volume flow rate examination revealed that the longer the acyl chain, the higher the thermoplasticity of the ester and that the esters exhibited higher thermoplasticity than structurally analogous esters made from cellulose and curdlan. A notable feature of the thermoplastic paramylon mixed esters is the availability of hot-pressing as a means of molding them into a film. Light transmittance and XRD measurements revealed that these films were transparent and in the amorphous state. Tensile tests indicated that the films had adequate mechanical strength comparable to those of the cellulose and curdlan analogues. PMID- 27702531 TI - Bacterial cellulose nanocrystals produced under different hydrolysis conditions: Properties and morphological features. AB - Bacterial cellulose (BC) is a polymer with interesting physical properties owing to the regular and uniform structure of its nanofibers, which are formed by amorphous (disordered) and crystalline (ordered) regions. Through hydrolysis with strong acids, it is possible to transform BC into a stable suspension of cellulose nanocrystals, adding new functionality to the material. The aim of this work was to evaluate the effects of inorganic acids on the production of BC nanocrystals (BCNCs). Acid hydrolysis was performed using different H2SO4 concentrations and reaction times, and combined hydrolysis with H2SO4 and HCl was also investigated. The obtained cellulose nanostructures were needle-like with lengths ranging between 622 and 1322nm, and diameters ranging between 33.7 and 44.3nm. The nanocrystals had a crystallinity index higher than native BC, and all BCNC suspensions exhibited zeta potential moduli greater than 30mV, indicating good colloidal stability. The mixture of acids resulted in improved thermal stability without decreased crystallinity. PMID- 27702532 TI - Microwave-assisted synthesis and characterization of hydrophilically functionalized polygalacturonic acid. AB - Microwave-assisted synthesis of a new class of polymeric surfactants based on polygalacturonic acid (PGA) is presented. PGA is water-insoluble and not surface active under normal conditions. Single-step hydrophilic modification of PGA with taurine (2-aminoethane sulfonic acid) renders it surface-active. The modification can be carried out either using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDCl) as a coupling agent or using microwave irradiation without a catalyst. Microwave irradiation significantly shortens reaction times and eliminates the need for a coupling agent. In all cases, functionalization was confirmed using 1H NMR, FTIR spectroscopy and elemental analysis. PGA-SO3 exhibits surface-active properties comparable to commercial surfactants, Triton X-100 and sodium lauryl sulfate. Detailed cytotoxicity evaluation performed using human dermal fibroblast (HDF) and human leukemic (HL-60) cell lines indicate that PGA-SO3 is not toxic even at 20 fold higher concentrations. These polymeric surfactants synthesized from PGA with no demonstrable cytotoxicity have the potential for serving as 'greener' alternatives to common petrochemical-based surfactants. PMID- 27702533 TI - Synthesis and characterization of regioselectively substituted curdlan hetero esters via an unexpected acyl migration. AB - Regioselectively substituted curdlan esters were synthesized by protecting the C6 primary hydroxyl group with a triphenylmethyl group followed by the acylation of the secondary hydroxyl groups at C2 and C4. The subsequent detritylation of C6 trityl group under acidic conditions revealed an unexpected acyl migration from C4 to C6. This unique acyl migration in curdlan was first observed, which haven't been reported in other polysaccharides such as cellulose. The rate of this migration was found to be dependent on the length of the acyl group, leading to the proposal of a new mechanism for this transformation. Based on these results, we synthesized 2,6-di-O-acetyl-4-O-propionyl-curdlan, which was fully characterized by 1H NMR, 13C NMR, COSY, HSQC and HMBC analyses. Thermogravimetric analysis and differential scanning calorimetry measurements revealed that the regioselective esterification to curdlan promoted its crystallization compared with randomly mixed ester derivatives. PMID- 27702534 TI - Combinatory approach of methacrylated alginate and acid monomers for concrete applications. AB - Polysaccharides, and especially alginate, can be useful for self-healing of cracks in concrete. Instead of weak electrostatic bonds present within calcium alginate, covalent bonds, by methacrylation of the polysaccharides, will result in mechanically stronger superabsorbent polymers (SAPs). These methacrylated alginate chains as backbone are combined with two acrylic monomers in a varying molar fraction. These SAPs show a moisture uptake capacity up to 110% their own weight at a relative humidity of 95%, with a negligible hysteresis. The swelling capacity increased (up to 246 times its own weight) with a decreasing acrylic acid/2 acrylamido-2-methylpropane sulfonic acid ratio. The SAPs also showed a thermal stability up to 200 degrees C. Interestingly, the SAP composed of alginate and acrylic acid exerted a very limited decrease in compressive strength (up to 7% with addition of 1wt% SAP) rendering this material interesting for the envisaged self-healing application. PMID- 27702535 TI - Fabrication of stable galactosylated alginate microcapsules via covalent coupling onto hydroxyl groups for hepatocytes applications. AB - Galactose moieties are covalently coupled with sodium alginate to enhance liver specific functions in microcapsules owing to the specific interaction between the galactose moieties and the asialoglycoprotein receptors (ASGPRs) of hepatocytes. In this study, galactosylated alginate (L-NH2-OH-alginate) based microcapsules with desirable stability and a suitable 3D microenvironment are designed and fabricated for primary hepatocyte applications. The designed L-NH2-OH-alginate is fabricated via the application of ethylenediamine grafted lactobionic acid (L NH2) onto the hydroxyl groups of sodium alginate so that the negatively charged carboxyl groups intact in L-NH2-OH-alginate can effectively bond with Ca2+ to form a stable three-dimensional gel network; a subsequent reaction with polycations forms a stable membrane of microcapsules. As a result, L-NH2-OH alginate based microcapsules exhibit an excellent mechanical stability. Moreover, with a higher degree of substitution in L-NH2-OH-alginate (DS 0.41), the hepatocytes entrapped in L-NH2-OH-alginate microcapsules exhibit better viability and well-maintained liver-specific functions. PMID- 27702536 TI - Natural killer cell-mediated cytotoxicity is increased by a type II arabinogalactan from Anoectochilus formosanus. AB - This study investigated the effects of a type II arabinogalactan from Anoectochilus formosanus (AGAF) on natural killer (NK) cell-mediated cytotoxicity and the possible underlying mechanisms. This study reported that sustained exposure to AGAF increased NK-92MI cell-mediated cytotoxicity in a time- and concentration-dependent manner, as characterized according to the cellular lactic dehydrogenase leakage from K562 leukemia cells. Additionally, antibody neutralization studies have reported that interferon (IFN)-gamma, but not perforin or tumor necrosis factor-alpha, released by NK-92MI NK cells is crucial in enhancing cytotoxicity through an autocrine loop. In this study, AGAF was further demonstrated to induce IFN-gamma expression, increasing the susceptibility to NK-92MI cell-mediated cytotoxicity through the toll-like receptor (TLR)-2, TLR4, extracellular signal-regulated kinase, p38 mitogen activated protein kinase, and nuclear factor-kappaB pathways. A pharmacological study revealed that Janus kinase 2/signal transducers and activators of the signal transducers and of transcription 3 signaling are involved in IFN-gamma induced NK cell-mediated cytotoxicity.

AB - Gum tragacanth (GT) gels are usually formed by using chemical crosslinkers which cause safety concerns owing to their toxicity. This study introduces a novel and safe method for gelation of GT in the presence of small amounts of polyvinyl alcohol (PVA) followed by successive freeze-thaw (F-T) cycles. Gel formation was performed at two GT: PVA mixing ratios (1:1 and 3:1), four F-T consecutive cycles and two different thawing temperatures (25 and 5 degrees C). Gel fraction, syneresis as well as mechanical properties and microstructural characteristics of the resultant gels were then studied. Gel fraction and mechanical properties improved by increasing F-T cycles and decreasing thawing temperature. Gel fraction increased by increasing the number of F-T cycles and decreasing the thawing temperature. Syneresis increased by increasing F-T cycles at GT: PVA mixing ratio of 1:1; whilst it was diminished at GT: PVA mixing ratio of 3:1. Microstructural observations by SEM confirmed mechanical properties. PMID- 27702538 TI - Impact of degree of oxidation on the physicochemical properties of microcrystalline cellulose. AB - Microcrystalline cellulose, a major component of cell wall of plants, is one of the most abundant natural materials, but the poor solubility of cellulose limits its applications. Cellulose is a linear glucan with exclusive beta 1->4 linkage. Oxidation carried out with TEMPO-NaBr-NaClO system can selectively oxidize the C6 of glucose residues in cellulose. This modification improves polysaccharide solubility and other physicochemical properties. In this work, the impact of degree of oxidation on solubility, degree of crystallization, thermostability, molecular weight and the structures of the resulting oligosaccharide products of selectively oxidized cellulose were investigated using x-ray diffraction, thermogravimetric analysis, gel permeation chromatography-multiple angle laser light scattering and ultrahigh performance liquid chromatography-electrospray quadrupole/time of flight-mass spectrometry, respectively. The physicochemical properties of selectively oxidized cellulose having different degrees of oxidation were carefully characterized providing a theoretical foundation for the more accurate selection of applications of oxidized celluloses.

AB - The interaction between glycine betaine-based cationic surfactant and algal polysaccharide kappa-carrageenan was studied by investigating the dilution effect of the surfactant/polymer assemblies driven by electrostatic interactions. Two aqueous solutions of cationic surfactant and kappa-carrageenan at two molar ratios (3.5 and 0.8) diluted with factors of 5 and 10 times, were tested by various analytical methods including a multiscale observation by Transmission Electron Microscopy (TEM) and Laser Scanning Confocal Microscopy (LSCM) to understand the solution behavior of surfactant and oppositely charged polymer at both nano- and micrometer scale. Raman spectroscopy as well as confocal Raman imaging were applied to give Supplementary information about the surfactant/polysaccharide interactions and the distribution of assemblies. These analyses confirmed the formation of singular hybrid surfactant/polymer nano-, microobjects and they revealed the influence of dilution on the nanostructures. These results give an insight of the mechanism of the dilution effect on surfactant/polymer assemblies that could be valuable in pharmaceutical formulations, food and cosmetics fields.

AB - A sequential two-step treatment with peracetic acid (PA) and alkaline peroxide (AP) at mild temperatures (20-35 degrees C) removed more than 98% of the lignin from oil palm empty fruit bunch (EFB) fiber. For each kilogram of EFB fiber treated, 200-250g of a solids fraction and 120-170g of a precipitate fraction were recovered after the treatment. Subsequent enzymatic hydrolysis (45 degrees C, 72h) of the recovered solids (excluding the precipitate) resulted in a glucose yield of 629.8+/-0.5g per kg of the original dry EFB biomass. Enzymatic hydrolysis of untreated EFB yielded only 3.0+/-0.0g glucose per kg of dry EFB. Therefore, the PA-AP pretreatment enhanced glucose recovery from EFB by nearly 210-fold. The total treatment time was 93h (a 9h PA treatment at 35 degrees C, a 12h treatment with AP (20 degrees C, 4% NaOH), 72h of enzymatic hydrolysis). PMID- 27702541 TI - Cellulose-g-poly(d-lactide) nanohybrids induced significant low melt viscosity and fast crystallization of fully bio-based nanocomposites. AB - Comb-like nanocrystal cellulose graft poly (d-lactide) (PDLA), i.e., NCC-g-PDLA nanohybrids were synthesized and compounded with poly (l-lactide) (PLLA) and poly (hydroxyalkanoate)s (PHA) to make fully biobased nanocomposites. Surprisingly, the complex viscosity of the PLLA/PHA melts was reduced by more than one order of magnitudes, viz. from 4000 to 100Pas by incorporation of 2-4wt% of the NCC-g-PDLA nanohybrids. Meanwhile, the crystallization of the PLLA component was accelerated by the NCC-g-PDLA nanohybrids due to the strong interaction between PDLA and PLLA macromolecules. The significant reduction in melt viscosity associating with unique core-shell-like microstructures due to the synergetic effect of the NCC-g PDLA nanohybrids and the PHA would facilitate the preparation of complex-shaped biomass articles and fibers under low(er) pressure and temperatures, which is beyond pure academic interest. PMID- 27702542 TI - Self-assembled high-strength hydroxyapatite/graphene oxide/chitosan composite hydrogel for bone tissue engineering. AB - Graphene hydrogel has shown greatly potentials in bone tissue engineering recently, but it is relatively weak in the practical use. Here we report a facile method to synthesize high strength composite graphene hydrogel. Graphene oxide (GO), hydroxyapatite (HA) nanoparticles (NPs) and chitosan (CS) self-assemble into a 3-dimensional hydrogel with the assistance of crosslinking agent genipin (GNP) for CS and reducing agent sodium ascorbate (NaVC) for GO simultaneously. The dense and oriented microstructure of the resulted composite gel endows it with high mechanical strength, high fixing capacity of HA and high porosity. These properties together with the good biocompatibility make the ternary composite gel a promising material for bone tissue engineering. Such a simultaneous crosslinking and reduction strategy can also be applied to produce a variety of 3D graphene-polymer based nanocomposites for biomaterials, energy storage materials and adsorbent materials. PMID- 27702543 TI - Bioactive potential and structural chracterization of sulfated polysaccharide from seaweed (Gracilaria corticata). AB - The Sulfated polysaccharide was purified through anion-exchange and gel permeation column chromatography. The isolated sulfated polysaccharide from C. corticata contains 84% of carbohydrate, 0% of protein, 19.7% of ash and 29.4% of moisture was found. The carbon, hydrogen, nitrogen and sulfur content as 33.19%, 5.91%, 7.21% and 3.75%. The molecular weight of sulfated polysaccharide was found to be 43kDa. The sugar was composed of (90.11%), glucose (5.47%), xylose (2.30%) and mannose (2.12%). The structural feature of sulfated polysachharide was studied through FT-IR and 1H NMR spectral analysis. Further the sulfated polysaccharide showed total antioxidant activity of 24.93%-75.21% at 50 250MUg/ml, DPPH free radical scavenging activity of 23.12%-73.01% at 10 160MUg/ml, ABTS scavenging activity of 15.8%-74.5% at 25-125MUg/ml hydroxyl radical scavenging activity 12.87-69.19% at 25-125MUg/ml and superoxide radical scavenging activity 28.10-78.11% at 50-250MUg/ml respectively. The sulfated polysaccharide has shown good antibacterial activity against human pathogen. PMID- 27702544 TI - Acylation of cellulose nanocrystals with acids/trifluoroacetic anhydride and properties of films from esters of CNCs. AB - To eliminate the effect of humidity on nanopapers from nanocellulose, esters of CNCs (ECNCs) were synthesized via acylation of cellulose nanocrystals (CNCs) with fatty acids and Trifluoroacetic anhydride (TFAA). The structure information of ECNCs was confirmed via FTIR, degree of substitution (DS) determination, and XRD, respectively. With the increase of DS, the ECNCs could be dissolved in dichloromethane, which provided a ready way for fabrication of ECNCs films via casting/evaporation method. The tensile property, transmittance, hydrophobicity, thermal property and oxygen permeability of films were tested with universal tensile tester, UV-vis spectrophotometer, Contact angle tester, Simultaneous thermal analyzer and Oxygen permeability tester, respectively. With the increase of DS, the contact angles of ECNCs increased, and the water uptake decreased. The enhancement of hydrophobicity promised the preservation of tensile parameters for films after water absorbing. The hydrophobicity, high transmittance, and high oxygen barrier property make films have potential application in packaging filed. PMID- 27702545 TI - Structure and chain conformation of a neutral polysaccharide from sclerotia of Polyporus umbellatus. AB - A water-soluble heteropolysaccharide (PUP60W-1) was purified from the hot water extract of sclerotia of P. umbellatus by chromatography with DEAE Sepharose Fast Flow and Sephacryl S200 High-Resolution. The primary structure of PUP60W-1 was elucidated by GC, GC-MS and NMR. PUP60W-1 was identified as a highly branched polysaccharide composed of fucose, glucose and galactose in a ratio of 1.0:0.9:13.3. The main repeating unit was identified as alpha-(1->6)-d galactopyranan backbone with substitution of terminal alpha-galactopyranosyl residues at O-2 for two out of every three main chain galactose residues. Its chain conformation was studied by atom force microscopy and size exclusion chromatography coupled with multiple detectors. The results revealed that PUP60W 1 had a molecular weight of 2.47*104Da with a polydispersity index of 1.04, and existed in water as compact sphere structures which could be disrupted into smaller spherical chain blocks after dispersion with sodium dodecyl sulfate. PMID- 27702546 TI - Plantago major seed mucilage: Optimization of extraction and some physicochemical and rheological aspects. AB - The effect of different extraction procedures on functional properties of mucilage extracted from Plantago major seed were investigated using response surface methodology. Extraction at 75 degrees C, using 1:60 water:seed ratio at pH 6.8 was the best condition for maximum yield (15.18%), emulsion stability (67.4%), foam stability (88.4%), solubility (97.36%) and water absorption capacity (39.74g/g) of mucilage. At this optimum point, PMSM had, on average 82.85% carbohydrate, 76.79 mgGAE/gdry total phenol content, 97.8mgg-1 total flavonoid content and 915.54MUgml-1 antioxidant activity. The results indicated that PMSM had average molecular weight of 1.2*106Da. FTIR analysis demonstrated the presence of carboxyl, hydroxyl and methyl groups and glycoside bonds. The chain flexibility parameter, activation energy, zeta-potential and droplet size for PMSM were determined as 946.09, 0.78*107J/kgmol, 15.23mV (at neutral pH) and 448.56nm, respectively. Intrinsic viscosity for PMSM in deionized water was 14.24dlg-1. PMID- 27702547 TI - Nicotine stabilization in composite sodium alginate based wafers and films for nicotine replacement therapy. AB - Composite wafers and films comprising HPMC and sodium alginate (SA) were formulated for nicotine (NIC) replacement therapy via the buccal route. Magnesium aluminium silicate (MAS) was added in different concentration ratios (0.25, 0.5, 0.75) to stabilize NIC and its effect on mechanical properties, internal and surface morphology, physical form, thermal properties, swelling, mucoadhesion, drug content and release behaviour of the formulations was investigated. MAS changed the physico-mechanical properties of the composite formulations causing a decrease in mechanical hardness, collapsed wafer pores, increased roughness of film surface, increase in crystallinity and decreased mucoadhesion of the wafers. However, MAS increased swelling in both films and wafers as well as interaction between NIC and SA, which increased drug-loading capacity. Further, MAS resulted in rapid and slow release of NIC from wafers and films respectively. The results suggest that the ideal formulation for the stabilization of NIC in the composite formulations was MAS 0.25. PMID- 27702548 TI - The effect of starch amylose content on the morphology and properties of melt processed butyl-etherified starch/poly[(butylene succinate)-co-adipate] blends. AB - In this study, butyl-etherified waxy and high amylose starches were melt processed with biodegradable poly[(butylene succinate)-co-adipate] (PBSA) to improve the long-term stability of the starch-based materials. Butyl etherification was believed to improve the compatibility of starch with PBSA matrix. Scanning electron microscopy results demonstrated that highly branched amylopectin structures in butyl-etherified starch have better chemical interaction with the PBSA matrix compared to linear amylose structures. Thermogravimetric analysis revealed that the thermal stability of the blends decreased with increasing starch loading for all starch types with varying amylose content; however, the nature of the starch controlled the mechanical properties of the blends. Furthermore, the differential scanning calorimetric and polarised optical microscopic results demonstrated that the degree of crystallinity of PBSA decreased with increasing loading of amylopectin content in starch. Therefore, this work reveals the possibility of improving the inherent properties of starch by blending with PBSA through careful selection of the amylose content in starch. PMID- 27702549 TI - Thioredoxin interacting protein mediates lipid-induced impairment of glucose uptake in skeletal muscle. AB - Insulin resistance (IR) is an important determinant of type-2 diabetes mellitus (T2DM). Free fatty acids (FFAs) induce IR by various mechanisms. A surfeit of circulating FFA leads to intra-myocellular lipid accumulation that induces mitochondrial ROS generation and worsens IR. However, the molecular mechanisms behind are unclear. We identified thioredoxin interacting protein (TxNIP), which is overexpressed in T2DM, to be a promoter of ROS-induced IR. We observed upregulation of TxNIP upon palmitate treatment in skeletal muscle cells that led to ROS generation and Glut-4 downregulation resulting in impaired glucose-uptake. FFA-induced overexpression of TxNIP gene was mediated through the activation of its bona-fide trans activator, ChREBP. Further, Palmitate-induced impairment in AMPK-SIRT-1 pathway resulted in overexpression of ChREBP. While Fenofibrate, abrogated PA-induced TxNIP expression and ROS generation in skeletal muscle cells, Saroglitazar, a dual PPARalpha/gamma-agonist, not only inhibited PA induced TXNIP expression but also led to greater improvement in glucose uptake. Taken together, TxNIP appears to be an important factor in FFA-induced ROS generation and IR in skeletal muscle cells, which can be modulated for the management of this complex disorder. PMID- 27702550 TI - Modulation of cytotoxic responses by targeting CD160 prolongs skin graft survival across major histocompatibility class I barrier. AB - CD160 is a glycosylphosphatidylinositol-anchored protein of the immunoglobulin superfamily. It exhibits a pattern of expression coincident in humans and mice that is mainly restricted to cytotoxic cells and to all intestinal intraepithelial T lymphocytes. B- and T-lymphocyte attenuator (BTLA) and CD160 interact with cysteine-rich domain 1 of the extracellular region of Herpesvirus entry mediator (HVEM). CD160 engagement by HVEM can deliver inhibitory signals to a small subset of human CD4 T cells and attenuate its proliferation and cytokine secretion, but can also costimulate natural killer cells or intraepithelial lymphocytes. In turn, CD160 and BTLA can also function as agonist ligands being capable of costimulating T cells through membrane HVEM. Based on the restricted pattern of CD160 expression in cytotoxic cells, we postulated that CD160 may represent a suitable target for immune intervention in the setting of transplantation to modulate allogeneic cytotoxic responses. We demonstrated that in vivo administration of anti-CD160 antibody in combination with anti-CD40 L antibody to limit CD4 T-cell help modulated cytotoxic responses in a major histocompatibility complex class I mismatched model of allogeneic skin graft transplantation (bm1 donor to C57BL/6 recipient) and significantly prolonged graft survival. The implementation of this strategy in transplantation may reinforce current immunosuppression protocols and contribute to a better control of CD8 T-cell responses. PMID- 27702551 TI - Are the SDGs leaving safer surgical systems behind? AB - The World Health Organisation (WHO) has set out its new aims for the post-2015 global agenda in the form of the Sustainable Development Goals (SDGs). Discussions around the historically neglected role of emergency and essential surgical interventions in global health has attracted widespread attention with the help of well-timed, high-profile reports including the Lancet Commission for Global Surgery [1]. The case for promoting safe surgery is clear with evidence suggesting that at least two-thirds of the years of life lost globally will be attributed to surgical conditions by 2025 [1]. In 2010 alone, almost 17 million lives, and more than 70 million disability-adjusted life years (DALYs) were lost due to surgically treatable conditions [1]. A central component of the SDGs is its renewed focus on health as a human right in the form of Universal Health Coverage (UHC). However, there are doubts as to how nations will be able to keep the 'promise of leaving no-one behind' without explicit reference to global surgery within the SDG framework [2]. PMID- 27702552 TI - The effect of culture medium and carrier on explant culture of human limbal epithelium: A comparison of ultrastructure, keratin profile and gene expression. AB - Patients with limbal stem cell deficiency (LSCD) often experience pain and photophobia due to recurrent epithelial defects and chronic inflammation of the cornea. Successfully restoring a healthy corneal surface in these patients by transplantation of ex vivo expanded human limbal epithelial cells (LECs) may alleviate these symptoms and significantly improve their quality of life. The clinical outcome of transplantation is known to be influenced by the quality of transplanted cells. Presently, several different protocols for cultivation and transplantation of LECs are in use. However, no consensus on an optimal protocol exists. The aim of this study was to examine the effect of culture medium and carrier on the morphology, staining of selected keratins and global gene expression in ex vivo cultured LECs. Limbal biopsies from cadaveric donors were cultured for three weeks on human amniotic membrane (HAM) or on tissue culture coated plastic (PL) in either a complex medium (COM), containing recombinant growth factors, hormones, cholera toxin and fetal bovine serum, or in medium supplemented only with human serum (HS). The expanded LECs were examined by light microscopy (LM), transmission electron microscopy (TEM), immunohistochemistry (IHC) for keratins K3, K7, K8, K12, K13, K14, K15 and K19, as well as microarray and qRT-PCR analysis. The cultured LECs exhibited similar morphology and keratin staining on LM, TEM and IHC examination, regardless of the culture condition. The epithelium was multilayered, with cuboidal basal cells and flattened superficial cells. Cells were attached to each other by desmosomes. Adhesion complexes were observed between basal cells and the underlying carrier in LECs cultured on HAM, but not in LECs cultured on PL. GeneChip Human Gene 2.0 ST microarray (Affymetrix) analysis revealed that 18,653 transcripts were >=2 fold up or downregulated (p <= 0.05). Cells cultured in the same medium (COM or HS) showed more similarities in gene expression than cells cultured on the same carrier (HAM or PL). When each condition was compared to HAM/COM, no statistical difference was found in the transcription level of the selected genes associated with keratin expression, stemness, proliferation, differentiation, apoptosis, corneal wound healing or autophagy. In conclusion, the results indicate that ex vivo cultures of LECs on HAM and PL, using culture media supplemented with COM or HS, yield tissues with similar morphology and keratin staining. The gene expression appears to be more similar in cells cultured in the same medium (COM or HS) compared to cells cultured on the same carrier (HAM or PL).

AB - Aim of the present study was to assess the cytokine gene expression in liver, kidney and spleen and histopathological changes in mice infected with buffalo and dog isolates of Trypanosoma evansi. Forty-four Swiss albino mice was divided into eleven groups of four mice each and injected subcutaneously with 1 * 105 trypanosomes of buffalo and dog isolate to twenty mice each, four mice served as control. Mice were examined for clinical signs, blood smear for trypanosome counts. Blood for PCR, liver, kidney, spleen, heart, lung, testis and abdominal muscle for histopathology and liver, kidney, spleen for cytokine gene expression studies, were collected. Mice showed dullness, lethargy, hunched back, sluggish movements on D4 and D5 in buffalo and dog isolate, respectively. Parasite count in blood varied between the two isolates of T. evansi. By PCR, trypanosome DNA was detected on D1 and D2 for buffalo and dog isolate, respectively. Splenomegaly was observed in mice infected with buffalo isolate but not with dog isolate. Histopathological changes were observed in liver, kidney, spleen and heart of mice but no changes in testis and abdominal muscles. Blood vessels of liver, heart, lung showed presence of trypanosomes in mice infected with buffalo isolate but not for dog isolate. Cytokine gene expression of IL-2, IL-4, IL-6, IL-12, TNF alpha and IFN-gamma increased in liver, kidney and spleen in both these isolates. However, the buffalo isolate exhibited pronounced increase in cytokine gene expression when compare to dog isolate of T. evansi. Anti-inflammatory cytokine gene IL-10 showed 50-60 and 10-20 folds increment in buffalo and dog isolates, respectively. This is the first report of IL-4, IL-6, IL-10 and IL-12 cytokine changes in mice infected with T. evansi. A variation in pathogenicity between buffalo and dog isolates was recorded indicating buffalo isolate of T. evansi remained more pathogenic in mice.

AB - BACKGROUND: Brown-Vialetto-Van Laere Syndrome (BVVLS), a rare neurological disorder characterized by bulbar palsies and sensorineural deafness, is mainly associated with defective riboflavin transporters encoded by the SLC52A2 and SLC52A3 genes. METHODS: Here we present a 16-year-old BVVLS patient belonging to a five generation consanguineous family from Indian ethnicity with two homozygous missense mutations viz., c.421C>A [p.P141T] in SLC52A2 and c.62A>G [p.N21S] in SLC52A3. RESULTS: Functional characterization based on 3H-riboflavin uptake assay and live-cell confocal imaging revealed that the effect of mutation c.421C>A [p.P141T] identified in SLC52A2 had a slight reduction in riboflavin uptake; on the other hand, the c.62A>G [p.N21S] identified in SLC52A3 showed a drastic reduction in riboflavin uptake, which appeared to be due to impaired trafficking and membrane targeting of the hRFVT-3 protein. CONCLUSIONS: This is the first report presenting mutations in both riboflavin transporters hRFVT-2 and hRFVT-3 in the same BVVLS patient. Also, c.62A>G [p.N21S] in SLC52A3 appears to contribute more to the disease phenotype in this patient than c.421C>A [p.P141T] in SLC52A2. PMID- 27702555 TI - What Adherence Measures Should Be Used in Trials of Home-Based Rehabilitation Interventions? A Systematic Review of the Validity, Reliability, and Acceptability of Measures. AB - OBJECTIVE: To systematically review methods for measuring adherence used in home based rehabilitation trials and to evaluate their validity, reliability, and acceptability. DATA SOURCES: In phase 1 we searched the CENTRAL database, NHS Economic Evaluation Database, and Health Technology Assessment Database (January 2000 to April 2013) to identify adherence measures used in randomized controlled trials of allied health professional home-based rehabilitation interventions. In phase 2 we searched the databases of MEDLINE, Embase, CINAHL, Allied and Complementary Medicine Database, PsycINFO, CENTRAL, ProQuest Nursing and Allied Health, and Web of Science (inception to April 2015) for measurement property assessments for each measure. STUDY SELECTION: Studies assessing the validity, reliability, or acceptability of adherence measures. DATA EXTRACTION: Two reviewers independently extracted data on participant and measure characteristics, measurement properties evaluated, evaluation methods, and outcome statistics and assessed study quality using the COnsensus-based Standards for the selection of health Measurement INstruments checklist. DATA SYNTHESIS: In phase 1 we included 8 adherence measures (56 trials). In phase 2, from the 222 measurement property assessments identified in 109 studies, 22 high-quality measurement property assessments were narratively synthesized. Low-quality studies were used as supporting data. StepWatch Activity Monitor validly and acceptably measured short-term step count adherence. The Problematic Experiences of Therapy Scale validly and reliably assessed adherence to vestibular rehabilitation exercises. Adherence diaries had moderately high validity and acceptability across limited populations. The Borg 6 to 20 scale, Bassett and Prapavessis scale, and Yamax CW series had insufficient validity. Low-quality evidence supported use of the Joint Protection Behaviour Assessment. Polar A1 series heart monitors were considered acceptable by 1 study. CONCLUSIONS: Current rehabilitation adherence measures are limited. Some possess promising validity and acceptability for certain parameters of adherence, situations, and populations and should be used in these situations. Rigorous evaluation of adherence measures in a broader range of populations is needed. PMID- 27702557 TI - TIMPing Fate: Why Pancreatic Cancer Cells Sojourn in the Liver.

AB - OBJECTIVE: To test the effect of combined intermittent hypoxia (IH) and body weight-supported treadmill training (BWSTT) on standing and dynamic balance in persons with incomplete spinal cord injury (iSCI). DESIGN: Randomized, triple blind, placebo-controlled study. SETTING: Rehabilitation medical centers. PARTICIPANTS: Study participants (N=35) with chronic iSCI with American Spinal Injury Association grades C and D (>1y postinjury) were randomly assigned to either IH plus BWSTT (n=18) or continued normoxia (placebo) plus BWSTT protocol (n=17). INTERVENTIONS: Participants received either IH (alternating 1.5min 9% inspired O2 with 1.5min 21% inspired O2, 15 cycles per day) or continued normoxia (21% O2) combined with 45 minutes of BWSTT for 5 consecutive days, followed by 3 times per week IH or normoxia plus BWSTT, for 3 additional weeks. MAIN OUTCOME MEASURES: Standing balance (normalized jerk and root-mean-square [RMS]) and dynamic balance (turning duration, cadence in a turn, and turn-to-sit duration) were assessed before and after IH and normoxia protocol by means of instrumented sway and instrumented timed Up and Go test. RESULTS: There was no significant difference in standing balance between interventions for both normalized jerk and RMS instrumented sway components (both P>.05). There was a significantly faster cadence (P<.001), turning duration (P<.001), and turn-to-sit duration (P=.001) in subjects receiving IH plus BWSTT, compared with placebo. CONCLUSIONS: A 4-week protocol of IH combined with locomotor training improves dynamic, but not standing, balance in persons with iSCI.

PMID- 27702561 TI - Diagnosis and Management of Low-Grade Dysplasia in Barrett's Esophagus: Expert Review From the Clinical Practice Updates Committee of the American Gastroenterological Association. AB - The purpose of this clinical practice update expert review is to define the key principles in the diagnosis and management of low-grade dysplasia (LGD) in Barrett's esophagus patients. The best practices outlined in this review are based on relevant publications, including systematic reviews and expert opinion (when applicable). Practice Advice 1: The extent of Barrett's esophagus should be defined using a standardized grading system documenting the circumferential and maximal extent of the columnar lined esophagus (Prague classification) with a clear description of landmarks and visible lesions (nodularity, ulceration) when present. Practice Advice 2: Given the significant interobserver variability among pathologists, the diagnosis of Barrett's esophagus with LGD should be confirmed by an expert gastrointestinal pathologist (defined as a pathologist with a special interest in Barrett's esophagus-related neoplasia who is recognized as an expert in this field by his/her peers). Practice Advice 3: Expert pathologists should report audits of their diagnosed cases of LGD, such as the frequency of LGD diagnosed among surveillance patients and/or the difference in incidence of neoplastic progression among patients diagnosed with LGD vs nondysplastic Barrett's esophagus. Practice Advice 4: Patients in whom the diagnosis of LGD is downgraded to nondysplastic Barrett's esophagus should be managed as nondysplastic Barrett's esophagus. Practice Advice 5: In Barrett's esophagus patients with confirmed LGD (based on expert gastrointestinal pathology review), repeat upper endoscopy using high-definition/high-resolution white-light endoscopy should be performed under maximal acid suppression (twice daily dosing of proton pump inhibitor therapy) in 8-12 weeks. Practice Advice 6: Under ideal circumstances, surveillance biopsies should not be performed in the presence of active inflammation (erosive esophagitis, Los Angeles grade C and D). Pathologists should be informed if biopsies are obtained in the setting of erosive esophagitis and if pathology findings suggest LGD, or if no biopsies are obtained, surveillance biopsies should be repeated after the anti-reflux regimen has been further intensified. Practice Advice 7: Surveillance biopsies should be performed in a four-quadrant fashion every 1-2 cm with target biopsies obtained from visible lesions taken first. Practice Advice 8: Patients with a confirmed histologic diagnosis of LGD should be referred to an endoscopist with expertise in managing Barrett's esophagus-related neoplasia practicing at centers equipped with high-definition endoscopy and capable of performing endoscopic resection and ablation. Practice Advice 9: Endoscopic resection should be performed in Barrett's esophagus patients with LGD with endoscopically visible abnormalities (no matter how subtle) in order to accurately assess the grade of dysplasia. Practice Advice 10: In patients with confirmed Barrett's esophagus with LGD by expert GI pathology review that persists on a second endoscopy, despite intensification of acid-suppressive therapy, risks and benefits of management options of endoscopic eradication therapy (specifically adverse events associated with endoscopic resection and ablation), and ongoing surveillance should be discussed and documented. Practice Advice 11: Endoscopic eradication therapy should be considered in patients with confirmed and persistent LGD with the goal of achieving complete eradication of intestinal metaplasia. Practice Advice 12: Patients with LGD undergoing surveillance rather than endoscopic eradication therapy should undergo surveillance every 6 months times 2, then annually unless there is reversion to nondysplastic Barrett's esophagus. Biopsies should be obtained in 4-quadrants every 1-2 cm and of any visible lesions. Practice Advice 13: In patients with Barrett's esophagus-related LGD undergoing ablative therapy, radiofrequency ablation should be used. Practice Advice 14: Patients completing endoscopic eradication therapy should be enrolled in an endoscopic surveillance program. Patients who have achieved complete eradication of intestinal metaplasia should undergo surveillance every year for 2 years and then every 3 years thereafter to detect recurrent intestinal metaplasia and dysplasia. Patients who have not achieved complete eradication of intestinal metaplasia should undergo surveillance every 6 months for 1 year after the last endoscopy, then annually for 2 years, then every 3 years thereafter. Practice Advice 15: Following endoscopic eradication therapy, the biopsy protocol of obtaining biopsies in 4 quadrants every 2 cm throughout the length of the original Barrett's esophagus segment and any visible columnar mucosa is suggested. Practice Advice 16: Endoscopists performing endoscopic eradication therapy should report audits of their rates of complete eradication of dysplasia and intestinal metaplasia and adverse events in clinical practice.

AB - Crude extracts of in vitro and in vivo cultures of two strains of Photorhabdus l. sonorensis (Enterobacteriaceae) were analyzed by TLC, HPLC-UV and LC-MS. Nine unique compounds with mass/charge ratios (m/z) ranging from 331.3 to 713.5 were found in MS analyses. Bioactivity of extracts was assessed on a selection of plant pathogens/pests and non-target species. Caborca strain extracts showed the highest activity against Helicoverpa zea (Lepidoptera: Noctuidae) neonates at all concentrations tested. Mortality ranged from 11% (at 10MUg/ml) to 37% (at 40MUg/ml). Strain CH35 extracts showed the highest nematicidal activity on Meloidogyne incognita (Tylenchida: Meloidogynidae) at 40MUg/ml. Low to no nematicidal activity was observed against the non-target species Steinernema carpocapsae (Rhabditida: Steinernematidae) and Caenorhabditis elegans (Rhabditida: Rhabditidae). Caborca extracts exhibited a strong antibiotic effect on Pseudomonas syringae (Pseudomonadales: Pseudomonadacedae) at 40MUg/ml, while both Caborca and CH35 extracts inhibited the growth of Bacillus subitillis (Bacillales: Bacillaceae) at 40MUg/ml. All extracts strongly inhibited the growth of the fungus Fusarium oxysporum (Hypocreales: Nectriceae) but not that of Alternaria alternata (Pleosporales: Pleosporaceae). Contrastingly, a moderate to high inhibitory effect was denoted on the non-target biocontrol fungus Beauveria bassiana (Hypocreales: Clavivipitaceae). PMID- 27702564 TI - Testosterone and androgen receptor gene polymorphism are associated with confidence and competitiveness in men. AB - A contribution to a special issue on Hormones and Human Competition. Studies in non-human animals and humans have demonstrated the important role of testosterone in competitive interactions. Here, we investigated whether endogenous testosterone levels predict the decision to compete, in a design excluding spite as a motive underlying competitiveness. In a laboratory experiment with real monetary incentives, 181 men solved arithmetic problems, first under a noncompetitive piece rate, followed by a competition incentive scheme. We also assessed several parameters relevant to competition, such as risk taking, performance, and confidence in one's own performance. Salivary testosterone levels were measured before and 20min after the competition task using mass spectrometry. Participants were also genotyped for the CAG repeat polymorphism of the androgen receptor gene, known to influence the efficacy of testosterone signaling in a reciprocal relationship to the number of CAG repeats. We observed a significant positive association between basal testosterone levels and the decision to compete, and that higher testosterone levels were related to greater confidence in one's own performance. Whereas the number of CAG repeats was not associated with the choice to compete, a lower number of CAG repeats was related to greater confidence in those who chose to compete, but this effect was attributable to the polymorphism's effect on actual performance. An increase in testosterone levels was observed following the experiment, and this increase varied with self-reported high-school math grades. We expand upon the latest research by documenting effects of the androgen system in confidence in one's own ability, and conclude that testosterone promotes competitiveness without spite. PMID- 27702566 TI - Oxidative Damage Control in a Human (Mini-) Organ: Nrf2 Activation Protects against Oxidative Stress-Induced Hair Growth Inhibition. AB - The in situ control of redox insult in human organs is of major clinical relevance, yet remains incompletely understood. Activation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2), the "master regulator" of genes controlling cellular redox homeostasis, is advocated as a therapeutic strategy for diseases with severely impaired redox balance. It remains to be shown whether this strategy is effective in human organs, rather than only in isolated human cell types. We have therefore explored the role of Nrf2 in a uniquely accessible human (mini-) organ: scalp hair follicles. Microarray and qRT-PCR analysis of human hair follicles after Nrf2 activation using sulforaphane identified the modulation of phase II metabolism, reactive oxygen species clearance, the pentose phosphate pathway, and glutathione homeostasis. Nrf2 knockdown (small interfering RNA) in cultured human hair follicles confirmed the regulation of key Nrf2 target genes (i.e., heme oxygenase-1, NAD(P)H dehydrogenase, quinone 1, glutathione reductase, glutamate-cysteine ligase catalytic subunit, ABCC1, peroxiredoxin 1). Importantly, Nrf2 activation significantly reduced reactive oxygen species levels and associated lipid peroxidation. Nrf2 preactivation reduced premature catagen and hair growth inhibition induced by oxidative stress (H2O2 or menadione), significantly ameliorated the H2O2-dependent increase in matrix keratinocyte apoptosis and reversed the reactive oxygen species-induced reduction in hair matrix proliferation. This study thus provides direct evidence for the crucial role of Nrf2 in protecting human organ function (i.e., scalp hair follicles) against redox insult. PMID- 27702567 TI - Inhibition of M1 macrophage activation in adipose tissue by berberine improves insulin resistance. AB - AIMS: Insulin resistance is associated with a chronic inflammation in adipose tissue which is propagated by a phenotypic switch in adipose tissue macrophage (ATM) polarization. This study aimed to investigate whether berberine, the major alkaloid of rhizoma coptidis, can improve insulin resistance through inhibiting ATM activation and inflammatory response in adipose tissue. MAIN METHODS: High fat-diet induced obese mice were administered oral with berberine (50mg/kg/day) for 14days. ATMs were analysed using FACS and insulin resistance was evaluated. Expressions of pro-inflammatory cytokines and activation of inflammatory pathways were detected. The chemotaxis of macrophages was measured. Glucose consumption and insulin signalling of adipocytes were examined. KEY FINDINGS: Berberine significantly decreased F4/80+/CD11c+/CD206- cells in the stromal vascular fraction from adipose tissue and improved glucose tolerance in obsess mice. In addition, berberine reduced the elevated levels of serum TNF-alpha, IL-6 and MCP 1 and the expressions of TNF-alpha, IL-6 and MCP-1 and attenuated the phosphorylation of JNK and IKKbeta and the expression of NF-kappaB p65 in the obese adipose tissue, Raw264.7 macrophages and 3T3-L1 adipocytes, respectively. The phosphorylation of IRS-1 (Ser307) was inhibited by berberine in adipose tissue and cultured adipocytes. The phosphorylation of AKT (Ser473) was increased in berberine-treated adipose tissue. Conditioned medium from adipocytes treated with berberine reduced the number of infiltrated macrophages. Berberine partly restored the impaired glucose consumption and the activation of IRS-1 (Ser307) in adipocytes induced by the activation of macrophages. SIGNIFICANCE: Our findings imply that berberine improves insulin resistance by inhibiting M1 macrophage activation in adipose tissue. PMID- 27702565 TI - IL-1beta-Induced Protection of Keratinocytes against Staphylococcus aureus Secreted Proteases Is Mediated by Human beta-Defensin 2. AB - Atopic dermatitis (AD) is a common chronic inflammatory skin disease that results in significant morbidity. A hallmark of AD is disruption of the critical barrier function of upper epidermal layers, causatively linked to environmental stimuli, genetics, and infection, and a critical current target for the development of new therapeutic and prophylactic interventions. Staphylococcus aureus is an AD associated pathogen producing virulence factors that induce skin barrier disruption in vivo and contribute to AD pathogenesis. We show, using immortalized and primary keratinocytes, that S. aureus protease SspA/V8 is the dominant secreted factor (in laboratory and AD clinical strains of S. aureus) inducing barrier integrity impairment and tight junction damage. V8-induced integrity damage was inhibited by an IL-1beta-mediated mechanism, independent of effects on claudin-1. Induction of keratinocyte expression of the antimicrobial/host defense peptide human beta-defensin 2 (hBD2) was found to be the mechanism underpinning this protective effect. Endogenous hBD2 expression was required and sufficient for protection against V8 protease-mediated integrity damage, and exogenous application of hBD2 was protective. This modulatory property of hBD2, unrelated to antibacterial effects, gives new significance to the defective induction of hBD2 in the barrier-defective skin lesions of AD and indicates therapeutic potential. PMID- 27702570 TI - Rapid tin-mediated access to a lysophosphatidylethanolamine (LPE) library: Application to positional LC/MS analysis for hepatic LPEs in non-alcoholic steatohepatitis model mice. AB - Even though lysophospholipids have attracted much interest in recent years on account of their unique bioactivity, research related to lysophospholipids is usually hampered by problems associated with standard sample preparation and discrimination of regioisomers. Herein, we demonstrate a quick tin-chemistry based synthetic route to lysophosphatidylethanolamines (LPEs) and its application in the positional analysis of hepatic LPEs in non-alcoholic steatohepatitis (NASH) model mice. We found that the preference of hepatic LPE regioisomer largely depends on the unsaturation of acyl chain in both control and NASH model mice. In addition, hepatic C18:2-LPE and C20:5-LPE levels were significantly lower in the NASH model mice than those in the control. The LC/MS technique based on the library of LPE regioisomers allows an accurate observation of hepatic LPE metabolism and might provide useful information to elucidate yet ambiguous pathogenesis of NASH. PMID- 27702568 TI - Endoscopist fatigue estimates and colonoscopic adenoma detection in a large community-based setting. AB - BACKGROUND AND AIMS: Endoscopist fatigue may impact colonoscopy quality, but prior studies conflict, and minimal data exist from community-based practices where most colonoscopies are performed. METHODS: Within a large, community-based integrated healthcare system, we evaluated the associations among 4 measures of endoscopist fatigue and colonoscopic adenoma detection from 2010 to 2013. Fatigue measures included afternoon versus morning colonoscopy and the number of GI procedures performed before a given colonoscopy, including consideration of prior procedure complexity. Analyses were adjusted for potential confounders using multivariate logistic regression. RESULTS: We identified 126 gastroenterologists who performed 259,064 total GI procedures (median, 6 per day; range, 1-24), including 76,445 screening and surveillance colonoscopies. Compared with morning examinations, colonoscopies in the afternoon were not associated with lower adenoma detection for screening examinations, surveillance examinations, or their combination (OR for combination, .99; 95% CI, .96-1.03). The number of procedures performed before a given colonoscopy, with or without consideration of prior procedure complexity, was also not inversely associated with adenoma detection (OR for adenoma detection for colonoscopies in the fourth quartile of fatigue based on the number of prior procedures performed vs colonoscopies performed as the first procedure of the day, .99; 95% CI, .94-1.04). CONCLUSIONS: In a large community-based setting, adenoma detection for screening and surveillance colonoscopies were not associated with either time of day or the number of prior procedures performed by the endoscopist, within the range of procedure volumes evaluated. The lack of association persisted after accounting for prior procedure complexity.

PMID- 27702572 TI - Acute high-intensity noise induces rapid Arc protein expression but fails to rapidly change GAD expression in amygdala and hippocampus of rats: Effects of treatment with D-cycloserine. AB - Tinnitus is a devastating auditory disorder impacting a growing number of people each year. The aims of the current experiment were to assess neuronal mechanisms involved in the initial plasticity after traumatic noise exposure that could contribute to the emergence of tinnitus and to test a potential pharmacological treatment to alter this early neural plasticity. Specifically, this study addressed rapid effects of acute noise trauma on amygdalo-hippocampal circuitry, characterizing biomarkers of both excitation and inhibition in these limbic regions, and compared them to expression of these same markers in primary auditory cortex shortly after acute noise trauma. To assess excitatory plasticity, activity-regulated cytoskeleton-associated (Arc) protein expression was evaluated in male rats 45 min after bilateral exposure to acute high intensity noise (16 kHz, 115 dB SPL, for 1 h), sufficient to cause acute cochlear trauma, a common cause of tinnitus in humans and previously shown sufficient to induce tinnitus in rat models of this auditory neuropathology. Western blot analyses confirmed that up-regulation of amygdalo-hippocampal Arc expression occurred rapidly post-noise trauma, corroborating several lines of evidence from our own and other laboratories indicating that limbic brain structures, i.e. outside of the classical auditory pathways, exhibit plasticity early in the initiation of tinnitus. Western blot analyses revealed no noise-induced changes in amygdalo-hippocampal expression of glutamate decarboxylase (GAD), the biosynthetic enzyme required for GABAergic inhibition. No changes in either Arc or GAD protein expression were observed in primary auditory cortex in this immediate post-noise exposure period, confirming other reports that auditory cortical plasticity may not occur until later in the development of tinnitus. As a further control, our experiments compared Arc protein expression between groups exposed to the quiet background of a sound-proof chamber to those exposed not only to the traumatic noise described above, but also to an intermediate, non traumatic noise level (70 dB SPL) for the same duration in each of these three brain regions. We found that non-traumatic noise did not up-regulate Arc protein expression in these brain regions. To see if changes in Arc expression due to acute traumatic noise exposure were stress-related, we compared circulating serum corticosterone in controls and rats exposed to traumatic noise at the time when changes in Arc were observed, and found no significant differences in this stress hormone in our experimental conditions. Finally, the ability of D-cycloserine (DCS; an NMDA-receptor NR1 partial agonist) to reduce or prevent the noise trauma related plastic changes in the biomarker, Arc, was tested. D-cycloserine prevented traumatic noise-induced up-regulation of Arc protein expression in amygdala but not in hippocampus, suggesting that DCS alone is not fully effective in eliminating regionally-specific early plastic changes after traumatic noise exposure. PMID- 27702573 TI - Revealing calcium fluxes by analyzing inhibition dynamics in action potential clamp. AB - In cardiac excitation-contraction coupling (ECC), calcium enters the cytosol via L-type Ca2+ channels (LTCC) and reverse Na+/Ca2+-exchange (NCXrev), or is released from the sarcoplasmic reticulum (SR) by Ca2+-induced Ca2+-release (CICR). The magnitude of Ca2+ influx via the different pathways varies with the state of the cell and is difficult to assess quantitatively, because changes in Ca2+ influx through one pathway affect the others. In rainbow trout ventricular myocytes, the role of the SR has been uncertain for decades. The aim of this work was therefore two-fold: 1) to develop a method to quantify the Ca2+ influx pathways, and 2) to determine the role of CICR from the SR in trout ventricular myocytes. The novelty of our developed method lies in the mathematical analysis of measured transsarcolemmal Ca2+ currents and their impact on the corresponding Ca2+ transient during gradual inhibition of the currents in action potential (AP) clamp. We tested the developed method using an excitation-contraction model and showed that the method was able to recover calcium fluxes from noisy synthetic data. We applied the approach to trout ventricular myocytes and quantified the relative contributions of different Ca2+ influx pathways in ECC and determined the kinetics of these fluxes. Under baseline conditions, NCXrev is the main transmembrane Ca2+ influx pathway contributing 29 +/- 6% (of the Ca2+ influx), LTCC 18 +/- 7%, and CICR 53 +/- 10% to overall Ca2+ transient. Thus, NCXrev is an important regulator of contractility and probably plays a role in the negative force-frequency relationship of trout ventricular preparations. These results demonstrate that trout and neonatal mammalian cardiomyocytes resemble each other not only in terms of morphology and energetics but ECC as well. In summary, the developed method resolves the major problem how to separate highly interconnected fluxes in AP clamp and allows to study Ca2+ fluxes in cardiomyocytes under conditions close to in vivo. PMID- 27702574 TI - Cell-free analysis of polyQ-dependent protein aggregation and its inhibition by chaperone proteins. AB - Protein misfolding and aggregation is one of the major causes of neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease and Huntington's disease. So far protein aggregation related to these diseases has been studied using animals, cultured cells or purified proteins. In this study, we show that a newly synthesized polyglutamine protein implicated in Huntington's disease forms large aggregates in HeLa cells, and successfully recapitulate the process of this aggregation using a translation-based system derived from HeLa cell extracts. When the cell-free translation system was pre-incubated with recombinant human cytosolic chaperonin CCT, or the Hsc70 chaperone system (Hsc70s: Hsc70, Hsp40, and Hsp110), aggregate formation was inhibited in a dose dependent manner. In contrast, when these chaperone proteins were added in a post translational manner, aggregation was not prevented. These data led us to suggest that chaperonin CCT and Hsc70s interact with nascent polyglutamine proteins co translationally or immediately after their synthesis in a fashion that prevents intra- and intermolecular interactions of aggregation-prone polyglutamine proteins. We conclude that the in vitro approach described here can be usefully employed to analyze the mechanisms that provoke polyglutamine-driven protein aggregation and to screen for molecules to prevent it.

PMID- 27702575 TI - Roles of 5-HT1A receptor in the expression of AMPA receptor and BDNF in developing mouse cortical neurons. AB - The possible interactions between serotonergic and glutamatergic systems during neural development and under the pathogenesis of depression remain unclear. We now investigated roles of 5-HT1A receptor in the mRNA expression of AMPA receptor subunits (GluR1 and GluR2) and brain-derived neurotrophic factor (BDNF) using primary culture of cerebral cortex of mouse embryos. Neurons at embryonic day 18 were cultured for 3days or 14days and then treated with 5-HT1A receptor agonist (8-OH-DPAT) for 3h or 24h. In neurons cultured for 3 days, 8-OH-DPAT treatment for both 3h and 24h increased the mRNA levels of BDNF and GluR1, but not GluR2. In neurons cultured for 14 days, however, 8-OH-DPAT had no effects on these mRNA levels. Next, we examined in vivo roles of 5-HT1A receptor by administration of 8 OH-DPAT to newborn mice. Twenty-four hours after the oral administration of 8-OH DPAT, the mRNA expression of BDNF was decreased in the frontal cortex, but had no effects on the mRNA expression of GluR1 and GluR2. Taken together, the present study suggests that 5-HT1A receptor activation modulates mRNA expression of AMPA receptor subunit and BDNF in cortical neurons, and the effects are different between in vitro and in vivo.

PMID- 27702579 TI - Priming with NO controls redox state and prevents cadmium-induced general up regulation of methionine sulfoxide reductase gene family in Arabidopsis. AB - In the present study we evaluated the pre-treatment (priming) of Arabidopsis thaliana plants with sodium nitroprusside (SNP), a NO-donor, as an interesting approach for improving plant tolerance to cadmium stress. We focused on the cell redox balance and on the methionine sulfoxide reductases (MSR) family as a key component of such response. MSR catalyse the reversible oxidation of MetSO residues back to Met. Five MSRA genes and nine MSRB genes have been identified in A. thaliana, coding for proteins with different subcellular locations. After treating 20 days-old A. thaliana (Col 0) plants with 100 MUM CdCl2, increased protein carbonylation in leaf tissue, lower chlorophyll content and higher levels of reactive oxygen species (ROS) in chloroplasts were detected, together with increased accumulation of all MSR transcripts evaluated. Further analysis showed reduction in guaiacol peroxidase activity (GPX) and increased catalase (CAT) activity, with no effect on ascorbate peroxidase (APX) activity. Pre-exposition of plants to 100 MUM SNP before cadmium treatment restored redox balance; this seems to be linked to a better performance of antioxidant defenses. Our results indicate that NO priming may be acting as a modulator of plant antioxidant system by interfering in oxidative responses and by preventing up-regulation of MSR genes caused by metal exposure. PMID- 27702580 TI - Short ECG segments predict defibrillation outcome using quantitative waveform measures. AB - AIM: Quantitative waveform measures of the ventricular fibrillation (VF) electrocardiogram (ECG) predict defibrillation outcome. Calculation requires an ECG epoch without chest compression artifact. However, pauses in CPR can adversely affect survival. Thus the potential use of waveform measures is limited by the need to pause CPR. We sought to characterize the relationship between the length of the CPR-free epoch and the ability to predict outcome. METHODS: We conducted a retrospective investigation using the CPR-free ECG prior to first shock among out-of-hospital VF cardiac arrest patients in a large metropolitan region (n=442). Amplitude Spectrum Area (AMSA) and Median Slope (MS) were calculated using ECG epochs ranging from 5s to 0.2s. The relative ability of the measures to predict return of organized rhythm (ROR) and neurologically-intact survival was evaluated at different epoch lengths by calculating the area under the receiver operating characteristic curve (AUC) using the 5-s epoch as the referent group. RESULTS: Compared to the 5-s epoch, AMSA performance declined significantly only after reducing epoch length to 0.2s for ROR (AUC 0.77-0.74, p=0.03) and with epochs of <=0.6s for neurologically-intact survival (AUC 0.72 0.70, p=0.04). MS performance declined significantly with epochs of <=0.8s for ROR (AUC 0.78-0.77, p=0.04) and with epochs <=1.6s for neurologically-intact survival (AUC 0.72-0.71, p=0.04). CONCLUSION: Waveform measures predict defibrillation outcome using very brief ECG epochs, a quality that may enable their use in current resuscitation algorithms designed to limit CPR interruption. PMID- 27702581 TI - Characteristics of automated external defibrillator coverage in Philadelphia, PA, based on land use and estimated risk. AB - AIM: Approximately 424,000 out-of-hospital cardiac arrests (OHCA) occur in the US annually. As automated external defibrillators (AED) are an important part of the community response to OHCA, we investigated how well the spatial demand (likelihood of OHCA) was met by the spatial supply (AEDs) in a dense urban environment. METHODS: Using geographic information system (GIS) software, we applied kernel density and optimized hot spot procedures with two differently sized radii to model OHCA incidence rates from existing studies, providing an estimate of OHCA likelihood at a given location. We compared these density maps to existing AED coverage in the study area. Descriptive statistics summarized coverage by land use. RESULTS: With a 420-ft buffer, we found that 56.0% (79.9%, 840-ft buffer) of the land area in the city center was covered by existing AEDs at, though 70.1 (91.5)% of the OHCA risk was covered using kernel density and 79.8% (98.1) was covered using hot spot analysis. CONCLUSIONS: The difference in coverage by area and risk seems to indicate efficient placement of existing AEDs. Our findings also highlight the possible benefits to expanding the influence of AEDs by lowering search times, and identify opportunities to improve AED coverage in the study area. This article offers one method by which local officials can use spatial data to prioritize attention for AED placement and coverage. PMID- 27702582 TI - Geminin a multi task protein involved in cancer pathophysiology and developmental process: A review. AB - DNA replicates in a timely manner with each cell division. Multiple proteins and factors are involved in the initiation of DNA replication including a dynamic interaction between Cdc10-dependent transcript (Cdt1) and Geminin (GMNN). A conformational change between GMNN-Cdt1 heterotrimer and heterohexamer complex is responsible for licensing or inhibition of the DNA replication. This molecular switch ensures a faithful DNA replication during each S phase of cell cycle. GMNN inhibits Cdt1-mediated minichromosome maintenance helicases (MCM) loading onto the chromatin-bound origin recognition complex (ORC) which results in the inhibition of pre-replication complex assembly. GMNN modulates DNA replication by direct binding to Cdt1, and thereby alters its stability and activity. GMNN is involved in various stages of development such as pre-implantation, germ layer formation, cell commitment and specification, maintenance of genome integrity at mid blastula transition, epithelial to mesenchymal transition during gastrulation, neural development, organogenesis and axis patterning. GMNN interacts with different proteins resulting in enhanced hematopoietic stem cell activity thereby activating the development-associated genes' transcription. GMNN expression is also associated with cancer pathophysiology and development. In this review we discussed the structure and function of GMNN in detail. Inhibitors of GMNN and their role in DNA replication, repair, cell cycle and apoptosis are reviewed. Further, we also discussed the role of GMNN in virus infected host cells. PMID- 27702583 TI - EEG asymmetry and BIS/BAS among healthy adolescents. AB - Asymmetry in frontal alpha activation (FAA) has been associated with specific behavior patterns. Greater activation in the left frontal cortex is related to "approach" motivation, while greater activation in the right cortex is associated with "withdrawal" motivation. Moreover, resting FAA is stable over time among adults. This stability has not been demonstrated among adolescents, and the correspondence between resting FAA and personality has been inconsistently observed. The present study examined stability of FAA and the association between resting FAA and behavioral activation among adolescents. At baseline and 4 months, 99 adolescents completed a resting electroencephalogram (EEG) and a pencil-and-paper measure of personality (BIS/BAS). FAA showed good stability over time (Intra-class correlation coefficient=0.65, p<0.001), but there was no correlation between FAA and personality. Results are interpreted in light of a capability model of FAA; namely, that asymmetry may emerge under conditions of stimulation and recede during resting. PMID- 27702584 TI - Untrustworthiness inhibits congruent facial reactions to happy faces. AB - This study investigated how trustworthiness modulates facial reactions to emotional faces, specifically emotional mimicry. In order to manipulate the trustworthiness of others, we used the trust game. The participants (N=37) perceived the partners as trustworthy or untrustworthy based on whether the partners tended to behave fairly or unfairly in the game with a within-subjects design. Facial electromyograms were measured while viewing the emotional faces displayed by the partners. The results demonstrated that the zygomaticus major activity in response to happy faces was greater for the trustworthy partners than for the untrustworthy partners. The results suggest that emotional mimicry of happiness is more inhibited for those who are non-affiliative and unfavorable, such as the untrustworthy partners. On the other hand, there was no effect of trustworthiness on congruent facial reactions to sad and angry faces. However, the zygomaticus major activity for angry faces was smaller for the trustworthy partners than for the untrustworthy partners, suggesting that positive expressions to angry faces of the trustworthy partners are inhibited. Trustworthiness constructed by social exchange modulates not only emotional mimicry for happy faces but also incongruent facial reactions to angry faces. PMID- 27702585 TI - Scanning electron microscopic analysis of using agarose hydrogel microenvironment to create enamel prism-like tissue on dentine surface. AB - OBJECTIVE: To investigate remineralisation of dentine in the hydrogel microenvironment for the management of hypersensitivity. METHODS: Human dentine slices were prepared from extracted sound human molars. They were acid-etched with phosphoric acid and put into the polyethylene tubes. The etched dentine surfaces were covered by a 2-mm-thick layer of CaCl2 agarose hydrogel. Another 2 mm-thick layer of ion-free agarose hydrogel was added on top of the CaCl2 agarose hydrogel. They were immersed into a solution containing phosphate and fluoride after gelification. The solution was replaced every 24h and the agarose hydrogels were replaced every 48h. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) were used to evaluate the formed crystals on dentine surface after 2, 4 and 6days. SEM was used to study the mineral formed in the replaced agarose hydrogels. RESULTS: Observation under SEM showed that crystals occluded the dentinal tubules and an enamel prism like tissue formed on the etched dentine surface. XRD and FTIR analyses confirmed the crystals were hydroxyapatite. Numerous calcium phosphate globules were found in the replaced calcium chloride agarose hydrogel. CONCLUSION: The hydrogel acts as the remineralisation microenvironment to initiate occlusion of dentinal tubules and formation of enamel prisms-like tissue on human dentine surface. CLINICAL SIGNIFICANCE: Remineralisation of dentine induced in this hydrogel microenvironment can be an alternative therapeutic technique for the management of dentine hypersensitivity. PMID- 27702586 TI - Physiological effects of a habituation procedure for functional MRI in awake mice using a cryogenic radiofrequency probe. AB - BACKGROUND: Functional magnetic resonance imaging (fMRI) in mice is typically performed under anesthesia due to difficulties in holding the head of awake mice stably with a conventional three-point fixation method that uses a tooth-bar and earplugs. Although some studies have succeeded in fMRI in awake mice by attaching a head-post on the skull, this cannot be applied to fMRI using a high signal-to noise ratio (SNR) cryogenic MRI-detector, CryoProbe, because it covers the head of a mouse closely. NEW METHOD: We developed head-fixation implements for awake mice that are applicable to fMRI using CryoProbe. RESULTS: A head-bar was surgically attached to the skull of a mouse that was then habituated to a mock fMRI-environment, two hours/day for eight days with physiological examinations of body-weight, fecal weight, electromyogram (EMG), and electrocardiogram. EMG power decreased with just one day of habituation, whereas heart rate decreased after at least seven days of habituation. Estimated head motions of awake mice during fMRI were significantly smaller than a voxel size. Unexpectedly, temporal SNR of fMRI signals for awake mice was higher than that for anesthetized mice held by a conventional method. Functional connectivity in the brain of both anesthetized and awake mice showed bilateral and unilateral networks. COMPARISON WITH EXISTING METHOD(S): fMRI using CryoProbe had been performed on anesthetized mice previously. Our method does not use anesthetics during habituation or fMRI. CONCLUSION: Our method would be beneficial for translational research using fMRI in mice and humans because human fMRI is typically performed without anesthetics. PMID- 27702587 TI - Using EP50 to forecast treatment adherence in individuals with multiple sclerosis. AB - Much like delay discounting, probability discounting may be related to a host of pro-health behaviors. In a recent report, a Medical Decision Making Questionnaire (MDMQ) was developed that leveraged this insights of probability discounting to both describe ways that multiple sclerosis (MS) patients weigh costs and benefits when making adherence choices, and predicted their self-reported treatment adherence. The current re-analysis of those data use a novel EP50 measure as a framework of a model that predicted the cost/benefit ratios necessary for the choices of typically non-adherent patients to become indistinguishable from those of typically adherent patients (and vice versa). These analytic tools may aid in the development/evaluation of both novel therapeutics and treatment adherence strategies for chronic conditions. PMID- 27702588 TI - Self-control mediates the relationship between time perspective and BMI. AB - Trait future time perspective measures the extent to which behaviour is dominated by a striving for future goals and rewards. Trait present time perspective measures orientation towards immediate pleasure. Previous research has explored the relationship between future and present time perspective and BMI with mixed findings. In addition, the psychological mechanism underlying this relationship is unclear. Self-control is a likely candidate, as it has been related to both BMI and time perspective, but the relationship between all of these concepts has not been examined in a single study. Therefore, the aim of this study was to examine if trait self-control mediates the relationship between time perspective (future and present) and BMI. Self-report time perspective (ZTPI), self-control (SCS) and height/weight data were collected using an online survey from a mixed student and community sample (N = 218) with wide ranging age (mean 29, SD 11, range 18-73 years) and BMI (mean 24, SD 4, range 15-43). The results of a structural equation model including both facets of time perspective suggested that the traits are related yet distinct measures that independently predict BMI through changes in self-control. Bootstrap mediation analysis showed that self control mediated the relationship between both future time perspective (95% CI, 0.10 to -0.02) and present time perspective (95% CI, 0.03 to 0.17), and BMI in opposite directions. Participants with higher future time perspective scores (higher present time perspective scores) had higher (lower) self-control, which predicted lower (higher) BMI. These results are consistent with previous research suggesting an important role for time perspective in health outcomes. Self control likely mediates the relationship between temporal perspectives and BMI, suggesting that time perspective may be a target for individualised interventions. PMID- 27702589 TI - Electrochemistry of cytochrome P450 17alpha-hydroxylase/17,20-lyase (P450c17). AB - Within the superfamily of cytochrome P450 enzymes (P450s), there is a small class which is functionally employed for steroid biosynthesis. The enzymes in this class appear to have a small active site to accommodate the steroid substrates specifically and snuggly, prior to the redox transformation or hydroxylation to form a product. Cytochrome P450c17 is one of these and is also a multi-functional P450, with two activities, the first 17alpha-hydroxylation of pregnenolone is followed by a subsequent 17,20-lyase transformation to dehydroepiandrosterone (DHEA) as the dominant pathways to cortisol precursors or androgens in humans, respectively. How P450c17 regulates these two redox reactions is of special interest. There is a paucity of direct electrochemical studies on steroidogenic P450s, and in this mini-review we provide an overview of these studies with P450c17. Historical consideration as to the difficulties in obtaining reliable electrochemistry due to issues of handling proteins on an electrode, together with advances in the electrochemical techniques are addressed. Recent work using Fourier transformed alternating current voltammetry is highlighted as this technique can provide both catalytic information simultaneously with the underlying redox transfer with the P450 haem. PMID- 27702590 TI - Annexin A6 regulates adipocyte lipid storage and adiponectin release. AB - Lipid storage and adipokine secretion are critical features of adipocytes. Annexin A6 (AnxA6) is a lipid-binding protein regulating secretory pathways and its role in adiponectin release was examined. The siRNA-mediated AnxA6 knock-down in 3T3-L1 preadipocytes impaired proliferation, and differentiation of AnxA6 depleted cells to mature adipocytes was associated with higher soluble adiponectin and increased triglyceride storage. The latter was partly attributed to reduced lipolysis. Accordingly, AnxA6 overexpression in 3T3-L1 adipocytes lowered cellular triglycerides and adiponectin secretion. Indeed, serum adiponectin was increased in AnxA6 deficient mice. Expression analysis identified AnxA6 protein to be more abundant in intra-abdominal compared to subcutaneous adipose tissues of mice and men. AnxA6 protein levels increased in white adipose tissues of obese mice and here, levels were highest in subcutaneous fat. AnxA6 protein in adipocytes was upregulated by oxidative stress which might trigger AnxA6 induction in adipose tissues and contribute to impaired fat storage and adiponectin release. PMID- 27702591 TI - Montelukast ameliorates streptozotocin-induced cognitive impairment and neurotoxicity in mice. AB - Extensive studies have demonstrated that neuroinflammation is associated with Alzheimer's disease (AD) and cysteinyl leukotriene receptor 1 (CysLT1R) was involved in neuroinflammation. Montelukast, a highly selective CysLT1R antagonist, has been reported to attenuate learning and memory impairments in the amyloid-beta-induced mouse model of AD. However, whether montelukast also exerts beneficial effects on streptozotocin (STZ)-induced memory deficits in mice is not well known. In the present study, we aimed to investigate the effects of montelukast on STZ-induced cognitive impairment, neuroinflammation and apoptosis in mice. Our data showed that intra-hippocampal microinfusion of STZ resulted in learning and memory impairments, including increased escape latency during acquisition trials and decreased exploratory activities in the probe trial in Morris watermaze (MWM) task, and decreased number of correct choices and increased latency to enter the shock-free compartment in Y-maze test, and caused neuroinflammatory and apoptotic responses, evidenced by increments of nuclear NF kappaB p65, TNF-alpha, IL-1beta, cleaved caspase-3, Bax as well as decreased expression of Bcl-2 in hippocampus. Interestingly, STZ treatment led to up regulation of protein and mRNA of CysLT1R in hippocampus. Of note, consecutive oral administration of montelukast (1 or 2mg/kg, 3 weeks) remarkably attenuated these effects induced by STZ. However, montelukast had no effect on normal mice. These results suggest that montelukast improves memory impairment and inhibits neuroinflammation and apoptosis in mice exposed to STZ. Montelukast may provide a novel strategy for treating or preventing AD. PMID- 27702592 TI - Alpha-naphthylisothiocyanate impairs bile acid homeostasis through AMPK-FXR pathways in rat primary hepatocytes. AB - Alpha-naphthylisothiocyanate (ANIT) is widely used to induce cholestasis in basic researches. Although direct damage induced by ANIT to bile duct epithelial cells has been documented in previous studies, few works investigated ANIT-induced effects on hepatocytes. Our previous study indicated that activated AMP-activated protein kinase (AMPK) inhibited farnesoid X receptor (FXR) expression and further participated in the pathogenesis of estrogen-induced cholestasis. However, whether ANIT has effects on bile acid homeostasis in hepatocytes, and the role of AMPK-FXR pathway played in these effects remain unclear. In this study, our results showed that ANIT induced intracellular bile acid accumulation without obvious cellular toxicity in sandwich cultured rat primary hepatocytes (SCRHs), accompanied with significant decreased expression of FXR and bile acid transporters. AMPK activation via ERK1/2-LKB1 pathway was critical for ANIT induced effects on hepatocytes. Compound C, specific AMPK inhibitor, blocked ANIT regulated gene expression, decreased bile acid accumulation and recovered bile canalicular structure both in vitro and in vivo. Furthermore, the expression of A1 adenosine receptor (A1AR), a potential cholestatic target, was relatively low in hepatocytes compared with expression in rat whole livers. Consistent with these findings, DPCPX, a classic antagonist of A1AR, had no effect on ANIT induced hepatocytes injury. In summary, our results indicate that AMPK-FXR signaling is critical for ANIT-induced toxic effects on hepatocytes, provide new insights into the pathogenesis of ANIT-induced cholestasis, and suggest AMPK-FXR pathway as a potential therapeutic target for cholestasis. PMID- 27702593 TI - Lipids and flaviviruses, present and future perspectives for the control of dengue, Zika, and West Nile viruses. AB - Flaviviruses are emerging arthropod-borne pathogens that cause life-threatening diseases such as yellow fever, dengue, West Nile encephalitis, tick-borne encephalitis, Kyasanur Forest disease, tick-borne encephalitis, or Zika disease. This viral genus groups >50 viral species of small enveloped plus strand RNA virus that are phylogenetically closely related to hepatitis C virus. Importantly, the flavivirus life cycle is intimately associated to host cell lipids. Along this line, flaviviruses rearrange intracellular membranes from the endoplasmic-reticulum of the infected cells to develop adequate platforms for viral replication and particle biogenesis. Moreover, flaviviruses dramatically orchestrate a profound reorganization of the host cell lipid metabolism to create a favorable environment for viral multiplication. Consistently, recent work has shown the importance of specific lipid classes in flavivirus infections. For instances, fatty acid synthesis is linked to viral replication, phosphatidylserine and phosphatidylethanolamine are involved on the entry of flaviviruses, sphingolipids (ceramide and sphingomyelin) play a key role on virus assembly and pathogenesis, and cholesterol is essential for innate immunity evasion in flavivirus-infected cells. Here, we revise the current knowledge on the interactions of the flaviviruses with the cellular lipid metabolism to identify potential targets for future antiviral development aimed to combat these relevant health-threatening pathogens. PMID- 27702594 TI - Structure and functionality of nanostructured triacylglycerol crystal networks. AB - In this review, recent advances in the characterization of the nanoscale structure of fat crystal networks are outlined. The effect of different factors on the properties of crystalline nanoplatelets (CNPs) is comprehensively described. These are discussed together with the observed changes in polymorphism and micro- or mesostructural properties so as to have a complete understanding of the influence of different internal and external factors on the material properties of fats. The relationship between the nanostructure and the material properties of fats (i.e., oil binding capacity and rheology) is also described. Characterization of the nanostructure of fats has provided a new dimension to the analysis of fat crystal networks and opportunities for nanoengineering that could result in innovations in the food industry with regards to processing and structuring fatty materials. PMID- 27702595 TI - Smart nanoparticles with a detachable outer shell for maximized synergistic antitumor efficacy of therapeutics with varying physicochemical properties. AB - Co-delivery systems capable of transporting hydrophobic chemotherapeutics and hydrophilic siRNA to the same cell population with simultaneous burst release of both drugs to maximize synergistic anticancer efficacy remains elusive. In this light, a multifunctional nanoparticle (HA-PSR) consisting of a redox-sensitive core and detachable crosslinked hyaluronic acid (HA) shell was developed. Octyl modified PEI containing disulfide linkages (PSR) were synthesized as the core materials for co-encapsulation of chemotherapeutics and siRNA, while a HAase sensitive thiolated HA (HA-SH) was collaboratively assembled to the anionic shell for CD44-mediated active targeting along with enhanced and detachable protection for drug loaded inner cores. Resultantly, HA de-protected redox-sensitive inner cores achieved co-burst release of both cargoes when triggered by glutathione (GSH) rich environments in cytoplasm. Results of in-vivo and in-vitro testing indicated successful co-encapsulation of hydrophobic drugs and hydrophilic siRNA with adjustable ratios. Selective delivery to CD44 overexpressing tumors was achieved through passive and active targeting, followed by HAase-triggered HA de shielding and GSH-triggered burst release of both cargos. Rapid intracellular trafficking maximized synergistic cytotoxicities of chemotherapeutics and siRNA for remarkable tumor inhibition in a xenograft animal tumor model. Consequently, the HA-PSR nanoparticle holds great potential for combined chemotherapeutics/siRNA treatment in cancer with maximized synergistic antitumor efficacy. PMID- 27702596 TI - DNA damage-induced inflammation and nuclear architecture. AB - Nuclear architecture and the chromatin state affect most-if not all- DNA dependent transactions, including the ability of cells to sense DNA lesions and restore damaged DNA back to its native form. Recent evidence points to functional links between DNA damage sensors, DNA repair mechanisms and the innate immune responses. The latter raises the question of how such seemingly disparate processes operate within the intrinsically complex nuclear landscape and the chromatin environment. Here, we discuss how DNA damage-induced immune responses operate within chromatin and the distinct sub-nuclear compartments highlighting their relevance to chronic inflammation. PMID- 27702597 TI - Sequence learning in Parkinson's disease: Focusing on action dynamics and the role of dopaminergic medication. AB - Previous studies on movement sequence learning in Parkinson's disease (PD) have produced mixed results. A possible explanation for the inconsistent findings is that some studies have taken dopaminergic medication into account while others have not. Additionally, in previous studies the response modalities did not allow for an investigation of the action dynamics of sequential movements as they unfold over time. In the current study we investigated sequence learning in PD by specifically considering the role of medication status in a sequence learning task where mouse movements were performed. The focus on mouse movements allowed us to examine the action dynamics of sequential movement in terms of initiation time, movement time, movement accuracy, and velocity. PD patients performed the sequence learning task once on their regular medication, and once after overnight withdrawal from their medication. Results showed that sequence learning as reflected in initiation times was impaired when PD patients performed the task ON medication compared to OFF medication. In contrast, sequence learning as reflected in the accuracy of movement trajectories was enhanced when performing the task ON compared to OFF medication. Our findings suggest that while medication enhances execution processes of movement sequence learning, it may at the same time impair planning processes that precede actual execution. Overall, the current study extends earlier findings on movement sequence learning in PD by differentiating between various components of performance, and further refines previous dopamine overdose effects in sequence learning. PMID- 27702598 TI - Juvenile Granulosa Cell Tumor of the Ovary: A Clinicopathologic Study. AB - STUDY OBJECTIVE: To report on the clinical characteristics and outcome of pediatric patients with juvenile granulosa cell tumor (JGCT) of the ovary. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Patients with histopathologically confirmed ovarian JGCT diagnosed between 1990 and 2016 were identified. Data on the clinical presentation, surgical management, oncologic management, laboratory investigation, follow-up, and outcome were collected. Tumors were staged according to the International Federation of Gynecology and Obstetrics criteria. RESULTS: Eight patients were diagnosed with ovarian JGCT during the study period. The median age at presentation was 3 years (range, 0.7-14 years). Precocious puberty was the presenting symptom in all five prepubertal children; abdominal distension due to mass effect was the presenting symptom in three children older than 9 years of age. In patients who had preoperative serologic testing, estradiol (n = 3) and inhibin (n = 3) levels were elevated. Five patients had stage I disease, and three had stage III. All stage I patients underwent salpingo-oophorectomy as the only treatment. Stage III patients received adjuvant chemotherapy. After a median follow-up of 6.2 years, six patients (75%) were alive without evidence of disease. One stage I patient with germline p53 mutation and phosphatase and tensin homolog mutation, died because of subsequent liposarcoma. One patient with stage IIIB disease developed recurrence detected according to an elevated inhibin serum level, and died due to progressive disease despite receiving multiple chemotherapy regimens. CONCLUSION: Juvenile granulosa cell tumor has a favorable prognosis in patients with stage I disease after surgical resection alone. Adjuvant chemotherapy might be indicated in patients with higher-stage tumors. PMID- 27702599 TI - Autonomic changes induced by provocative motion in rats bred for high (HAB) and low (LAB) anxiety-related behavior: Paradoxical responses in LAB animals. AB - In humans, associations between anxiety and nausea (including motion-induced) are reported but the underlying mechanisms are not known. Hypothermia is proposed to be an index of nausea in rats. Utilising hypothermia and heart rate as outcome measures we investigated the response to provocative motion in rats selectively bred for high (HAB) and low (LAB) anxiety-related behaviors and in non-selected (NAB) rats to further elucidate the potential relationship between hypothermia and nausea-like state. Core temperature and electrocardiogram were monitored in each group (n=10 per group) using telemetry, with or without circular motion (40min; 0.75Hz) and vehicle or diazepam (2mg/kg, i.p.) pre-treatment. Heart rate and time- and frequency-domain parameters of heart rate variability were derived from the electrocardiogram. There was no baseline difference in core temperature between the three groups (mean 38.0+/-0.1 degrees C), but HAB animals had a significantly lower resting heart rate (330+/-7bpm) compared to LAB (402+/-5bpm) and NAB (401+/-9bpm). Animals in all groups exhibited hypothermia during motion (HAB: 36.3+/-0.1 degrees C; NAB: 36.4+/-0.1 degrees C; LAB: 34.9+/-0.2 degrees C) with the magnitude (area under the curve, AUC) of the response during 40-min motion being greater in LAB compared to NAB and HAB rats, and this was also the case for the motion-induced bradycardia. Diazepam had minimal effects on baseline temperature and heart rate in all groups, but significantly reduced the hypothermia response (AUC) to motion in all groups by ~30%. Breeding for extremes in anxiety-related behavior unexpectedly selects animals with low trait anxiety that have enhanced bradycardia and hypothermic responses to motion; consequently, this animal model appears to be not suitable for exploring relationships between anxiety and autonomic correlates of nausea. Thermal and cardiovascular responses to motion were little different between HAB and NAB rats indicating that either hypothermia is not an index of a nausea-like state in rats, or that the positive correlation between anxiety and nausea demonstrated in humans does not exist in rats. The mechanism underlying the enhanced physiological responses in LAB requires more detailed study and may provide a novel model to investigate factors modulating motion sensitivity. PMID- 27702600 TI - Evaluation of neuron-glia integrity by in vivo proton magnetic resonance spectroscopy: Implications for psychiatric disorders. AB - Proton magnetic resonance spectroscopy (1H-MRS) has been widely applied in human studies. There is now a large literature describing findings of brain MRS studies with mental disorder patients including schizophrenia, bipolar disorder, major depressive disorder, and anxiety disorders. However, the findings are mixed and cannot be reconciled by any of the existing interpretations. Here we proposed the new theory of neuron-glia integrity to explain the findings of brain 1H-MRS stuies. It proposed the neurochemical correlates of neuron-astrocyte integrity and axon-myelin integrity on the basis of update of neurobiological knowledge about neuron-glia communication and of experimental MRS evidence for impairments in neuron-glia integrity from the authors and the other investigators. Following the neuron-glia integrity theories, this review collected evidence showing that glutamate/glutamine change is a good marker for impaired neuron-astrocyte integrity and that changes in N-acetylaspartate and lipid precursors reflect impaired myelination. Moreover, this new theory enables us to explain the differences between MRS findings in neuropsychiatric and neurodegenerative disorders. PMID- 27702601 TI - Towards universal approach for bacterial production of three-finger Ly6/uPAR proteins: Case study of cytotoxin I from cobra N. oxiana. AB - Cytotoxins or cardiotoxins is a group of polycationic toxins from cobra venom belonging to the 'three-finger' protein superfamily (Ly6/uPAR family) which includes small beta-structural proteins (60-90 residues) with high disulfide bond content (4-5 disulfides). Due to a high cytotoxic activity for cancer cells, cytotoxins are considered as potential anticancer agents. Development of the high throughput production methods is required for the prospective applications of cytotoxins. Here, efficient approach for bacterial production of recombinant analogue of cytotoxin I from N. oxiana containing additional N-terminal Met residue (rCTX1) was developed. rCTX1 was produced in the form of E. coli inclusion bodies. Refolding in optimized conditions provided ~6 mg of correctly folded protein from 1 L of bacterial culture. Cytotoxicity of rCTX1 for C6 rat glioma cells was found to be similar to the activity of wild type CTX1. The milligram quantities of 13C,15N-labeled rCTX1 were obtained. NMR study confirmed the similarity of the spatial structures of recombinant and wild-type toxins. Additional Met residue does not perturb the overall structure of the three-finger core. The analysis of available data for different Ly6/uPAR proteins of snake and human origin revealed that efficiency of their folding in vitro is correlated with the number of proline residues in the third loop and the surface area of hydrophobic residues buried within the protein interior. The obtained data indicate that hydrophobic core is important for the folding of proteins with high disulfide bond content. Developed expression method opens new possibilities for structure-function studies of CTX1 and other related three-finger proteins. PMID- 27702602 TI - Proteocephalid tapeworms (Cestoda: Onchoproteocephalidea) of loaches (Cobitoidea): Evidence for monophyly and high endemism of parasites in the Far East. AB - The parasite fauna of loaches (Cypriniformes: Cobitoidea), a group of small bottom-dwelling freshwater fishes with a mostly Eurasian distribution, remains a largely unknown quantity. Here we revise the taxonomy of tapeworms of the genus Proteocephalus Weinland, 1858 (Cestoda: Proteocephalidae) that had been found in loaches from the Palaearctic Region (Central Europe, Japan and Russia [Primorsky Region]). Molecular phylogenetic analysis based on two nuclear (ssr- and lsrDNA) and two mitochondrial genes (cox1 and rrnL) revealed a monophyletic group consisting of four valid species nesting within the Proteocephalus-aggregate: (i) Proteocephalus sagittus (Grimm, 1872) from Barbatula barbatula (Europe, Russia and Tajikistan), (ii) Proteocephalus demshini n. sp. from Barbatula toni (Russian Far East - Primorsky Region), (iii) Proteocephalus midoriensis Shimazu, 1990 from Lefua echigonia (Japan) and L. costata (Russia) (new host and geographical record), and (iv) Proteocephalus misgurni n. sp. from Misgurnus anguillicaudatus (Russia; Primorsky Region). Proteocephalus sagittus and P. demshini, and P. midoriensis and P. misgurni were recovered as sister taxa, respectively. Proteocephalus sagittus and P. demshini are characterized by having proglottids that are wider than long, an elongate to pyriform cirrus-sac and the vitelline follicles that form wide lateral bands. Proteocephalus midoriensis and P. misgurni are characterized by having proglottids that are more elongate and an ovoid to almost spherical cirrus-sac and the vitelline follicles forming narrow lateral bands. Proteocephalus demshini differs from P. sagittus in the posterolateral extent of the vitelline follicles, whereas P. misgurni can be distinguished from P. midoriensis mainly by the relative size of the ovary, posterior extent of the vitelline follicles and width of the scolex. Unlike most species of the Proteocephalus-aggregate that possess an apical sucker, all species from loaches are devoid of any apical organ. The existence of two new species in loaches from the Primorsky Region of Russia indicates high endemism of fish parasites in this region. A key to the identification of recognized species from loaches is provided. PMID- 27702603 TI - Isoliquiritigenin exhibits anti-proliferative properties in the pituitary independent of estrogen receptor function. AB - The plant flavonoid isoliquiritigenin (ISL) is a botanical estrogen widely taken as an herbal supplement to ease the symptoms of menopause. ISL has been also shown to have anti-tumor properties in a number of cancer cell backgrounds. However, the effects of ISL on normal cells are less well known and virtually unstudied in the context of the pituitary gland. We have established a pituitary explant culture model to screen chemical agents for gene expression changes within the pituitary gland during a period of active proliferation and differentiation. Using this whole-organ culture system we found ISL to be weakly estrogenic based on its ability to induce Cckar mRNA expression, an estrogen receptor (ER) mediated gene. Using a range of ISL from 200nM to 200MUM, we discovered that ISL promoted cell proliferation at a low concentration, yet potently inhibited proliferation at the highest concentration. ICI 182,780 failed to antagonize ISL's repression of pituitary cell proliferation, indicating the effect is independent of ER signaling. Coincident with a decrease in proliferating cells, we observed down-regulation of transcript for cyclin D2 and E2 and a strong induction of mRNA and protein for the cyclin dependent kinase inhibitor Cdkn1a (p21). Importantly, high dose ISL did not alter the balance of progenitor vs. differentiated cell types within the pituitary explants and they seemed otherwise healthy; however, TUNEL staining revealed an increase in apoptotic cell death in ISL treated cultures. Our results merit further examination of ISL as an anti-tumor agent in the pituitary gland. PMID- 27702604 TI - Evaluation of MALDI-TOF MS (Matrix-Assisted Laser Desorption-Ionization Time-of Flight Mass Spectrometry) for routine identification of anaerobic bacteria. AB - Information regarding the use of MALDI-TOF MS as an alternative to conventional laboratory methods for the rapid and reliable identification of bacterial isolates is still limited. In this study, MALDI-TOF MS was evaluated on 295 anaerobic isolates previously identified by 16S rRNA gene sequencing and with biochemical tests (Rapid ID 32A system, BioMerieux). In total, 85.8% of the isolates were identified by MALDI-TOF MS at the species level vs 49.8% using the Rapid ID 32A system (p < 0.0001). None of the isolates was discordantly identified at the genus level using MALDI-TOF MS and only 9 of them could not be identified using the method. Thus, our results show that MALDI-TOF MS is a robust and reliable tool for the identification of anaerobic isolates in the microbiology laboratory. Its implementation will reduce the turnaround time for a final identification and the number of isolates that require 16S rRNA sequencing. PMID- 27702605 TI - In-vivo high resolution AFM topographic imaging of Caenorhabditis elegans reveals previously unreported surface structures of cuticle mutants. AB - Atomic force microscopy (AFM) is a powerful method for topographic imaging of surfaces with nanometer resolution. AFM offers significant advantages over scanning electron microscopy (SEM) including the acquisition of quantitative 3D images and biomechanical information. More importantly, for in-vivo biological imaging, AFM does not require sample dehydration/labeling. We show for the first time high-resolution topographical images of the cuticle of the model organism C. elegans under physiological conditions using AFM. C. elegans is used extensively for drug screening and to study pathogen adherence in innate immunity; both applications highly depend on the integrity of the nematode's cuticle. Mutations affecting both drug adsorption and pathogen clearance have been proposed to relate to changes in the cuticle structure, but never visually examined in high resolution. In this study we use AFM to visualize the topography of wild-type adult C. elegans as well as several cuticle collagen mutants and describe previously unseen anatomical differences. PMID- 27702606 TI - Nanotheranostic approaches for management of bloodstream bacterial infections. AB - Bloodstream bacterial infections are a serious threat to global public health and economy. The recent figures released by National Center for Health Statistics indicate that more than a million Americans get affected by it each year and the sepsis mortality alone is about 28%-50% Hall et al. (2011).1 Robust and affordable point-of-care medical technologies are, therefore, urgently needed for rapid decision-making to initiate appropriate line of treatment. Current techniques based on blood culture and serology do not have quick turnaround times or adequate sensitivities for early intervention. Moreover, antimicrobial resistance poses a great challenge in the fight towards effective bacterial infection management. Nanotheranostics is emerging as a novel strategy combining solutions for rapid diagnosis and treatment in a more personalized way. This review highlights the recent advances made in theranosis of bloodstream bacterial infections using different classes of nanomaterials and bioreceptors, and discusses present challenges and future way forward. PMID- 27702607 TI - Development and diabetes on the fly. AB - We review the use of a model organism to study the effects of a slow course, degenerative disease: namely, diabetes mellitus. Development and aging are biological phenomena entailing reproduction, growth, and differentiation, and then decline and progressive loss of functionality leading ultimately to failure and death. It occurs at all biological levels of organization, from molecular interactions to organismal well being and homeostasis. Yet very few models capable of addressing the different levels of complexity in these chronic, developmental phenomena are available to study, and model organisms are an exception and a welcome opportunity for these approaches. Genetic model organisms, like the common fruit fly, Drosophila melanogaster, offer the possibility of studying the panoply of life processes in normal and diseased states like diabetes mellitus, from a plethora of different perspectives. These long-term aspects are now beginning to be characterized. PMID- 27702608 TI - Multifaceted properties of 1,4-dimethylcarbazoles: Focus on trimethoxybenzamide and trimethoxyphenylurea derivatives as novel human topoisomerase II inhibitors. AB - Natural or synthetic carbazole derivatives have recently attracted the attention of the scientific world because of their multiple biological activity, leading to an increase of designed, synthesized and studied analogues. In this paper, four 1,4-dimethylcarbazole derivatives, analogues of Ellipticine, have been investigated for their ability to block cancer cells growth, with low effects on the proliferation of normal cells. DNA topoisomerases inhibition assays, docking simulations, stability studies and effects on a membrane model are reported. Particularly, compounds 2 and 3 have been found thermally stable and able to inhibit, strongly and selectively, the human DNA topoisomerase II. These properties confer a good and broad antitumoral activity in vitro, with very low cytotoxic effect on the proliferation of normal cell lines and without damaging, in contrast with Ellipticine, the cell membrane model. The presented outcomes set the most active compounds as good candidates for pre-clinical studies useful in cancer treatment. PMID- 27702609 TI - Enhancing the efficiency of thiomers: Utilizing a highly mucoadhesive polymer as backbone for thiolation and preactivation. AB - The objective of this study was to develop a novel thiomer with enhanced mucoadhesive properties using a highly mucoadhesive polymeric backbone. FixomerTM A-30 (poly(methacrylic acid-co-sodium acrylamidomethyl propane sulfonate)), exhibiting a mucoadhesive strength superior to that of all other polymers, was thiolated by conjugation with l-cysteine and furthermore preactivated with 2 mercaptonicotinic acid (MNA). The resulting derivatives Fix-SH and Fix-S-MNA exhibited coupling rates of 755MUmol thiol groups and 304MUmol MNA per gram polymer, respectively. The mucoadhesive profile was evaluated with three different methods: tensile studies, rotating cylinder and rheological synergism. In tensile studies, a total work of adhesion of above 500MUJ was determined for the unmodified polymer that increased to around 750MUJ after thiolation and around 1500MUJ after preactivation. The adhesion time of Fix-SH on the rotating cylinder was 3.7-fold and that of Fix-S-MNA 6.8-fold longer compared to the unmodified polymer. A rheological synergism was observed for the unmodified polymer as well as the derivatives with a non-significant difference for Fix-SH but a 5.44-fold improvement for Fix-S-MNA. Fix-S-MNA showed a significantly improved swelling behavior with a water-uptake up to the 30-fold of its initial weight over >50h whereas thiolation showed only slight improvements. Derivatization had no significant influence on cell viability. According to the results, Fix-S-MNA seems to be a suitable polymer for mucoadhesive drug delivery systems. PMID- 27702611 TI - Long-term home monitoring of intraocular pressure in pediatric glaucoma. AB - PURPOSE: Diurnal fluctuation of intraocular pressure (IOP), implicated in progression of adult glaucoma, has been reported in children only in the context of office and short-term home monitoring. The purpose of this study was to evaluate long-term patterns of IOP fluctuation and changes resulting from outflow enhancing intervention in pediatric glaucoma. METHODS: Parent-measured home-based rebound tonometry (Icare, Finland Oy) in pediatric glaucoma patients was studied prospectively. IOP was monitored for more than 1 month, with requested measurements at least 3 times daily. Demographic and glaucoma-related information were collected for each participant. IOP was recorded at home on electronic data sheets. It was then evaluated for trends including mean overall IOP, IOP pre- and post-planned IOP-lowering interventions, and IOP spikes over determined time intervals. RESULTS: IOP was measured in 14 eyes of 7 children (mean age, 9.3 +/- 2.4 years) over a mean of 164.3 days (range, 75-341), with a mean of 2.46 readings daily. Six eyes of 5 children underwent attempted outflow improvement, with improved mean IOP before versus after intervention (26.6 vs 15.5 mm Hg, P < 0.0001) and decreased mean daily IOP fluctuation (8.4 vs 4.6 mm Hg, P < 0.001) for each. An IOP reading 20% greater than mean for an individual eye over the entire period (a pressure "spike") occurred in 19.3 +/- 6.7% over 1 day, 62.9 +/- 18.0% over 3 days, 80.8 +/- 12.2% over 7 days, and 92.9 +/- 9.4% over 14 days. CONCLUSIONS: Long-term home monitoring in pediatric glaucoma proved feasible in this study population and often demonstrated large IOP fluctuations. A 14-day period of home monitoring provided >90% chance of identifying an IOP spike. Successful outflow improvement lowered both mean IOP and mean daily IOP fluctuations. PMID- 27702612 TI - Impact of number and quality of retinal images in a telemedicine screening program for ROP: results from the e-ROP study. AB - BACKGROUND: Telemedicine for the detection of retinopathy of prematurity (ROP) is becoming increasingly common; however, obtaining the required multiple retinal images from an infant can be challenging. This secondary analysis from the Telemedicine Approaches to Evaluating Acute-Phase Retinopathy of Prematurity (e ROP) study evaluated the detection of referral-warranted ROP (RW-ROP) by trained readers when a full set of 5 retinal images could not be obtained. METHODS: A total of 7,905 image sets from 1,257 infants in the study were evaluated. Retinal location of images and image quality were recorded. Sensitivity and specificity of RW-ROP detection by trained readers were calculated by comparing findings in incomplete image sets to the findings on standard eye examination. RESULTS: The majority of image sets contained all 5 retinal images (92.8%). The disk center view was the image most likely to be present and to be of acceptable image quality (96.8%). The nasal retina was the most difficult to obtain with acceptable image quality (83.4%). Sensitivity of detection of RW-ROP was 82.1% when 5 retinal images of acceptable quality were submitted for grading, 67.2% when 4 acceptable images were submitted, and 66.7% for 3 or fewer acceptable images (P = 0.02), with corresponding specificity of 82.2%, 89.0%, and 81.7% respectively (P < 0.0001). When images of any quality were evaluated, sensitivity was not increased (P = 0.74). CONCLUSIONS: The likelihood of detecting RW-ROP by telemedicine screening is decreased when a full set of retinal images is not obtained.

AB - RATIONAL: The human perirhinal cortex (PRC) plays critical roles in episodic and semantic memory and visual perception. The PRC consists of Brodmann areas 35 and 36 (BA35, BA36). In Alzheimer's disease (AD), BA35 is the first cortical site affected by neurofibrillary tangle pathology, which is closely linked to neural injury in AD. Large anatomical variability, manifested in the form of different cortical folding and branching patterns, makes it difficult to segment the PRC in MRI scans. Pathology studies have found that in ~97% of specimens, the PRC falls into one of three discrete anatomical variants. However, current methods for PRC segmentation and morphometry in MRI are based on single-template approaches, which may not be able to accurately model these discrete variants METHODS: A multi-template analysis pipeline that explicitly accounts for anatomical variability is used to automatically label the PRC and measure its thickness in T2-weighted MRI scans. The pipeline uses multi-atlas segmentation to automatically label medial temporal lobe cortices including entorhinal cortex, PRC and the parahippocampal cortex. Pairwise registration between label maps and clustering based on residual dissimilarity after registration are used to construct separate templates for the anatomical variants of the PRC. An optimal path of deformations linking these templates is used to establish correspondences between all the subjects. Experimental evaluation focuses on the ability of single-template and multi-template analyses to detect differences in the thickness of medial temporal lobe cortices between patients with amnestic mild cognitive impairment (aMCI, n=41) and age-matched controls (n=44). RESULTS: The proposed technique is able to generate templates that recover the three dominant discrete variants of PRC and establish more meaningful correspondences between subjects than a single-template approach. The largest reduction in thickness associated with aMCI, in absolute terms, was found in left BA35 using both regional and summary thickness measures. Further, statistical maps of regional thickness difference between aMCI and controls revealed different patterns for the three anatomical variants.

It provides a detailed functional plan to dissect an organism, tissue by tissue. Therefore comparative epigenomics may increase understanding of human acquired traits, by revealing regulatory changes in systems such as the neurological, musculoskeletal, and immunological. Enhancer loci evolve fast by hijacking elements from other tissues or rewiring and amplifying existing units for human-specific function. Promoters by contrast often require a CpG dense genetic infrastructure. Specific interplay occurs between the two, but also a shared modality of function, with coordination from global chromatin-modifying enzymes. Changes in specific transcription factor binding sites also facilitate the local epigenetic state. In the case of CTCF, these may further influence 3 dimensional structure and interaction. How these mechanistic units are modulated between tissue and species enables more comprehensive understanding of human processes and pathology. With this information, precise therapeutic targeting of these epigenetic modifications may become possible. PMID- 27702614 TI - Streamlined structure elucidation of an unknown compound in a pigment formulation. AB - A fast and reliable quality control is important for ink manufacturers to ensure a constant production grade of mixtures and chemical formulations, and unknown components attract their attention. Structure elucidating techniques seem time consuming in combination with column-based methods, but especially the low solubility of pigment formulations is challenging the analysis. In contrast, layer chromatography is more tolerant with regard to pigment particles. One PLC plate for NMR and FTIR analyses and one HPTLC plate for recording of high resolution mass spectra, MS/MS spectra and for gathering information on polarity and spectral properties were needed to characterize a structure, exemplarily shown for an unknown component in pigment Red 57:1 to be 3-hydroxy-2-naphtoic acid. A preparative layer chromatography (PLC) workflow was developed that used an Automated Multiple Development 2 (AMD 2) system. The 0.5-mm PLC plate could still be operated in the AMD 2 system and allowed a smooth switch from the analytical to the preparative gradient separation. Through automated gradient development and the resulting focusing of bands, the sharpness of the PLC bands was improved. For NMR, the necessary high load of the target compound on the PLC plate was achieved via a selective solvent extraction that discriminated the polar sample matrix and thus increased the application volume of the extract that could maximally be applied without overloading. By doing so, the yield for NMR analysis was improved by a factor of 9. The effectivity gain through a simple, but thoroughly chosen extraction solvent is often overlooked, and for educational purpose, it was clearly illustrated and demonstrated by an extended solvent screening. Thus, PLC using an automated gradient development after a selective extraction was proven to be a new powerful combination for structural elucidation by NMR. PMID- 27702616 TI - Internal standards for use in the comprehensive analysis of polychlorinated aromatic hydrocarbons using gas chromatography combined with multiphoton ionization mass spectrometry. AB - To decrease health-risks to humans, non-toxic compounds were evaluated for use as internal standards for calibrating data obtained by gas chromatography/multiphoton ionization mass spectrometry (GC-MPI-MS) using an ultraviolet femtosecond laser as the ionization source. The retention time in the mass chromatogram was calibrated using a retention index, in which a series of n alkanes was employed as internal standards for evaluating the retention times for polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinated biphenyls (PCBs). To compensate for changes in signal intensity in MPI-MS, the dependence of signal intensity on the laser pulse energy was investigated for the dioxin-like compounds, in addition to five non-toxic aromatic hydrocarbons, that were used as internal standards. Based on their similar behavior,the non-toxic PCDD/PCDF, its 13C-isotope, and pentachlorobenzene behave similarly, we conclude that they can be used for calibrating the signal intensities in MPI-MS. PMID- 27702615 TI - Development of a 45kpsi ultrahigh pressure liquid chromatography instrument for gradient separations of peptides using long microcapillary columns and sub-2MUm particles. AB - Commercial chromatographic instrumentation for bottom-up proteomics is often inadequate to resolve the number of peptides in many samples. This has inspired a number of complex approaches to increase peak capacity, including various multidimensional approaches, and reliance on advancements in mass spectrometry. One-dimensional reversed phase separations are limited by the pressure capabilities of commercial instruments and prevent the realization of greater separation power in terms of speed and resolution inherent to smaller sorbents and ultrahigh pressure liquid chromatography. Many applications with complex samples could benefit from the increased separation performance of long capillary columns packed with sub-2MUm sorbents. Here, we introduce a system that operates at a constant pressure and is capable of separations at pressures up to 45kpsi. The system consists of a commercially available capillary liquid chromatography instrument, for sample management and gradient creation, and is modified with a storage loop and isolated pneumatic amplifier pump for elevated separation pressure. The system's performance is assessed with a complex peptide mixture and a range of microcapillary columns packed with sub-2MUm C18 particles. PMID- 27702617 TI - A solid-phase microextraction coating of sol-gel-derived perhydroxy cucurbit[6]uril and its application on to the determination of polycyclic aromatic hydrocarbon. AB - A novel solid-phase microextraction coating that contains perhydroxy cucurbit[6]uril((OH)12Q[6]) was prepared by a sol-gel method. (OH)12Q[6] was used as a starting coating material with hydroxy-terminated poly(dimethylsiloxane) (OH PDMS) to bond chemically to a fused-silica substrate using 3-(2 cyclooxypropoxyl)propyltrimethoxysilane as cross-linking agent; hydrolysis and polycondensation reactions then led to the formation of a (OH)12Q[6]/PDMS coating. The coating has a high thermal stability (360 degrees C), long lifetime and can withstand organic and inorganic solvent rinsing because of the chemical binding between the coating and silica substrate. Its performance was tested by headspace (HS) solid-phase microextraction fiber coupled with gas chromatography to determine polycyclic aromatic hydrocarbon (PAHs) compounds in water samples. The (OH)12Q[6]/PDMS-coated fiber exhibited higher enrichment factors from fourfold for naphthalene to tenfold for pyrene compared with commercial PDMS fiber, and the enrichment factors increased with the number of condensed PAH rings. The strong adsorption affinity is believed to be attributed to hydrogen bonding and CH?pi interactions between PAHs and (OH)12Q[6], according to the results of quantum chemical calculations. In the PAH analysis, the (OH)12Q[6] coated fiber showed a good repeatability (<4.7%) and reproducibility between fibers (<9.4%), low detection limits (0.03-0.15MUgL-1), and a wide linearity (0.1 1000MUgL-1) under optimized conditions. This method was used for the simultaneous determination of seven PAHs with satisfactory recoveries of 90.56%-107.4% for Huaxi river water samples and 90.23%-109.5% for local wastewater samples, respectively. PMID- 27702618 TI - Detecting cognitive changes in preclinical Alzheimer's disease: A review of its feasibility. AB - Significant progress has been made in characterizing the biological changes occurring in preclinical Alzheimer's disease (AD). Cognitive dysfunction has been viewed, however, as a late-stage phenomenon, despite increasing evidence that changes may be detected in the decades preceding dementia. In the absence of comprehensive evidence-based guidelines for preclinical cognitive assessment, longitudinal cohort and neuroimaging studies have been reviewed to determine the temporal order and brain biomarker correlates of specific cognitive functions. Episodic memory decline was observed to be the most salient cognitive function, correlating with high levels of amyloid deposition and hypoconnectivity across large-scale brain networks. Prospective studies point to early decline in both episodic and semantic memory processing as well as executive functions in the predementia period. The cognitive tests have, however, been principally those used to diagnose dementia. New procedures are required which target more finely the medial temporal lobe subregions first affected by clinically silent AD pathology. PMID- 27702619 TI - Recommended cognitive outcomes in preclinical Alzheimer's disease: Consensus statement from the European Prevention of Alzheimer's Dementia project. AB - The Horizon 2020/IMI European Prevention of Alzheimer's Dementia (EPAD) project will undertake large-scale proof-of-concept trials in predementia Alzheimer's disease (AD). Within EPAD, the monitoring of cognitive trajectories in the preclinical period will constitute a central outcome measure; however, there are currently no clear guidelines as to how this should be achieved as most measures have been developed for the period around dementia diagnosis. The EPAD Scientific Advisory Group for Clinical and Cognitive Outcomes identified appropriate cognitive measures based on a literature search covering both cognitive correlates of preclinical brain changes from imaging studies and cognitive changes observed over time in nondementia population cohorts developing incident dementia. These measures were evaluated according to the following criteria: validity, coherence with biomarker changes, psychometric properties, cross cultural suitability, availability of alternative forms, and normative data limited practice effects. The resulting consensus statement provides recommendations for both future drug trials and research into preclinical Alzheimer's disease. PMID- 27702620 TI - Trends in Prevalence of Diagnosed Ocular Disease and Utilization of Eye Care Services in American Veterans. AB - PURPOSE: To assess trends in prevalence of diagnosed ocular disease and use of eye care services in the Veterans Affairs (VA) health care system. DESIGN: Prevalence study. METHODS: We performed a retrospective study of all eligible veterans in the VA Capitol Health Care Network from 2007 to 2011. The VA database was used to abstract demographic and socioeconomic variables, including age, race, sex, marital status, service connection, prescription copay, homelessness, and VA facility. Primary outcome measures were the prevalence of diagnosed ocular disease and use of eye care. Ocular diagnoses were determined by International Classification of Diseases, 9th revision codes and use by prescription medication fills, visits to eye care clinics, and cataract surgery frequency. RESULTS: The average age of veterans ranged from 59.8-60.9, most veterans were male (88.1 89.8%), and there was a high proportion of African Americans (29.5-30%). The prevalence of all ocular diagnoses increased from 20.5% in 2007 to 23.3% in 2011 (P < .01), a 13.7% increase. Similarly, the prevalence of diagnosed cataract increased by 35.7% (P = .02) from 7.1% in 2007 to 9.6% in 2011. Diagnosed glaucoma prevalence increased by 9.4% (P = .03) from 6.7 to 7.4%. The percent of patients seen in eye clinics increased 11.6%% in the 5-year study period to 24.0% in fiscal year 2011 (P = .05). The use of ophthalmic medications increased 20% (P < .01). The rate of cataract surgery did not change significantly during the study period. CONCLUSIONS: The prevalence of diagnosed eye conditions among American Veterans is increasing, as is the use of eye care services. Cataract surgery rates did not increase, which may indicate a need to increase availability of these services. PMID- 27702621 TI - Relationships Between Anthropometric Measurements and Intraocular Pressure: The Korea National Health and Nutrition Examination Survey. AB - PURPOSE: To evaluate the relationship between intraocular pressure (IOP) and various anthropometric measures. DESIGN: A population-based cross-sectional study. METHODS: A total of 5008 participants, 2080 men and 2928 women >=19 years of age were included from the Korea National Health and Nutrition Examination Survey V database, focusing on the years 2010 and 2011. We selected IOP in the right eye of a normal healthy population as the outcome variable of our study. We analyzed the relationship between IOP and anthropometric parameters using dual energy X-ray absorptiometry by sex. Lean body mass was calculated as total body mass minus fat mass. We used general linear models and logistic regression analysis to evaluate risk factors of high IOP. Our main outcome measure was correlation between anthropometric data and IOP. RESULTS: In multivariate general linear models, greater body mass index (BMI) and waist circumference were correlated with higher IOP for both men (BMI, beta = 0.053, P = .026; waist circumference, beta = 0.016, P = .067) and women (BMI, beta = 0.074, P < .001; waist circumference, beta = 0.028, P < .001). Greater fat mass (beta = 0.027, P = .037) and fat mass/lean body mass (beta = 1.170, P = .06) were correlated with higher IOP, while greater lean body mass/weight (beta = -3.188, P = .025), lean body mass/BMI (beta = -1.379, P = .002), appendicular skeletal muscle mass/BMI (beta = -2.270, P = .022), and bone mineral content/BMI (beta = -11.653, P = .031) were correlated with lower IOP in women, but not in men (P > .10). CONCLUSIONS: In healthy women, greater fat mass was associated with higher IOP, and greater muscle mass was associated with lower IOP after adjusting for weight and BMI. Fat and muscle influenced IOP in women independently. PMID- 27702622 TI - Intraoperative Interface Fluid Dynamics and Clinical Outcomes for Intraoperative Optical Coherence Tomography-Assisted Descemet Stripping Automated Endothelial Keratoplasty From the PIONEER Study. AB - PURPOSE: To correlate intraoperative interface fluid dynamics during Descemet stripping automated endothelial keratoplasty (DSAEK) using intraoperative optical coherence tomography (iOCT) in the Prospective Intraoperative and Perioperative Ophthalmic Imaging with Optical Coherence Tomography (PIONEER) study with postoperative outcomes. DESIGN: Prospective consecutive, interventional, comparative case series. PARTICIPANTS: One hundred seventy-eight eyes of 173 patients undergoing DSAEK from the Cole Eye Institute, Cleveland, Ohio. METHODS: Eyes that underwent DSAEK between October 2011 and March 2014 from the PIONEER intraoperative and perioperative OCT study were included. An automated interface fluid segmentation algorithm evaluated intraoperative dynamics of interface fluid before and after surgical manipulations. iOCT images were also captured at multiple intraoperative time points for 2 different DSAEK techniques, 1 that used an active air infusion system and 1 that did not. MAIN OUTCOME MEASURES: Interface fluid metrics, graft nonadherence. RESULTS: iOCT measurements of interface fluid after final surgical manipulations and immediately before leaving the operating room identified that total fluid volume (P = .002), largest fluid volume pocket (P = .002), max fluid area (P = .006), mean fluid thickness (P = .03), and max fluid thickness (P = .01) significantly correlated with graft nonadherence rates within the first postoperative week. After placement and optimization of intraoperative lenticle adherence, iOCT revealed a significant difference between the area, volume, and thickness of maximum fluid pockets between the 2 surgical techniques, but both techniques resulted in significant reduction of interface fluid during the procedure. CONCLUSIONS: Larger residual interface fluid volume, area, and thickness at the end of surgery detected with iOCT are associated with early graft nonadherence and can be quantified with an automated algorithm. iOCT imaging can successfully capture technique-dependent differences in fluid dynamics during DSAEK. PMID- 27702623 TI - Changes in Ocular Parameters and Intraocular Lens Powers in Aging Cycloplegic Eyes. AB - PURPOSE: Age-related changes in lens elasticity and ciliary muscle contractility can affect how ocular parameters respond to cycloplegia, and therefore intraocular lens (IOL) power measurements calculated by formulas using anterior chamber depth (ACD), lens thickness (LT), or white-to-white (WtW) for effective lens position prediction can vary. In response, using swept-source optical biometry in prepresbyopic and presbyopic eyes, we investigated changes in ocular parameters and IOL power calculations attributable to cycloplegia. DESIGN: Cross sectional study. METHODS: In 38 prepresbyopic and 42 presbyopic eyes, we measured pupil diameter, radius of corneal curvature values, central corneal thickness, WtW, ACD, LT, and axial length both before and after cycloplegia. We determined IOL power calculations with the Sanders-Retzlaff-Kraff/theoretical, Holladay 2, and Haigis formulas. To pinpoint the effect of cycloplegia, we recorded refractive predictions in pre- and postdilation conditions according to the same IOL power calculations, even if postdilation IOL power calculations had changed. RESULTS: With cycloplegia, pupil diameter changed significantly more in presbyopic eyes (P < .001). Central corneal thickness decreased in prepresbyopic eyes (P = .048), whereas WtW increased in presbyopic eyes (P = .02). In both groups, ACD and LT changed significantly (P < .001). IOL power calculations according to the Holladay 2 formula differed in prepresbyopic eyes (P = .042), and refractive predictions with the Holladay 2 and Haigis formulas differed significantly in prepresbyopic eyes (P = .043 and P = .022, respectively). CONCLUSION: Surgeons should consider the effect of cycloplegia on refractive prediction errors and IOL power calculations determined with Haigis and Holladay 2 formulas, especially in prepresbyopic ages. PMID- 27702624 TI - Outcomes With As-Needed Aflibercept and Macular Laser Following the Phase III VISTA DME Trial: ENDURANCE 12-Month Extension Study. AB - PURPOSE: To determine whether the efficacy and safety achieved with 2.0 mg intravitreal aflibercept injections (IAIs) for diabetic macular edema (DME) during the phase III VISTA DME trial were maintained with individualized, as needed treatment. DESIGN: Phase IV, multicenter, open-label extension study. METHODS: Sixty patients completing VISTA DME elected to enter the ENDURANCE extension study. All patients received IAIs in the presence of clinically relevant DME. Patients were observed at 4-, 8-, or 12-week intervals depending on the need for treatment. Main outcome measures were mean IAIs given through month 12 (M12), the proportion of patients receiving no IAIs, and the role of macular laser in decreasing treatment burden among patients requiring ongoing IAIs. RESULTS: A mean of 4.5 IAIs were administered through M12. Eighteen (30%) patients required no IAIs, and among those who met IAI retreatment criteria, a mean of 6.0 IAIs were administered through M12. Best-corrected visual acuity gains achieved during VISTA DME were maintained and stable with individualized dosing during ENDURANCE, fluctuating by <1.5 mean letters from the baseline at all time points. Likewise, mean central retinal thickness remained relatively stable during ENDURANCE. Thirty-seven (62%) patients met macular laser criteria at a mean of 19.5 weeks with no significant difference in the frequency of IAIs before or after macular laser. CONCLUSION: Vision gains achieved during the 3 year VISTA DME trial were maintained through M12 of the ENDURANCE extension study with a reduced treatment frequency, with 30% of patients receiving no IAIs. No significant reduction in IAI frequency was observed after macular laser application. PMID- 27702625 TI - Metformin, beyond an insulin sensitizer, targeting heart and pancreatic beta cells. AB - Metformin, a biguanide derivate, is known as the first-line antidiabetic agent for type 2 diabetes mellitus (T2DM) treatment. It reduces insulin resistance and decreases blood glucose concentration by inhibiting gluconeogenesis and suppressing hepatic glucose production with improved peripheral tissue insulin sensitivity. As an insulin sensitizer, metformin takes pleiotropic actions and exerts protective effects on multiple organs mainly in insulin-targeted tissues such as liver, muscle, and adipose tissues. Recent studies discover that metformin also plays essential roles in heart and pancreatic beta cells - two important organs in metabolic regulation. Metformin not only protects T2DM patients from cardiovascular diseases and heart failure, but also restores insulin secretion activities and protects pancreatic beta cells from lipotoxicity or glucotoxicity. Although accumulated evidence shed light on the metformin action, the precise mechanism of metformin is still under investigation. Further laboratory investigations and clinical trials are needed to pinpoint a map of metformin action. Based on recent findings, this review characterizes the beneficial role of metformin in cardiovascular diseases and pancreatic beta cells. PMID- 27702627 TI - Combined damage produced by multiple mild cerebral insults assessed using MRI in neonatal rats. AB - PURPOSE: To determine whether damage to neonatal brain is exacerbated with multiple mild cerebral insults as detected with MRI and corroborated using histology. MATERIALS AND METHODS: The combined brain injury produced by multiple procedures was compared in neonatal rats having: Sham surgery at P5, Sham surgery at P5 plus a diffuse mild transient unilateral cerebral hypoxia ischemia (HI) at P7, HI alone, and a minor photothrombotic (PT) stroke at P5 followed by HI. MRI after the ischemic insults was followed by final histology. RESULTS: PT produced lesions with increased T2 and decreased apparent diffusion coefficient for water (ADC) but no significant effects of a second HI. However, near the PT lesion/parietal cortex there were patchy areas of enhanced T2 and decreased ADC in 6/9, 3/8 and 0/8 animals in the PT+HI, Sham+HI and HI groups, respectively (P<0.05). Patches corresponded histologically to increased vacuolation and cell death and were more pronounced in the PT+HI and Sham+PT groups than the HI group. CONCLUSION: The extent of damage produced by a minor neonatal stroke followed by a diffuse HI two days later results in heterogeneous enhancement of T2, ADC and histological injury near the lesion. Surgical procedures including mechanical head manipulation followed by HI also produced some enhanced heterogeneity of hypoxic-ischemic injury affirming the need for sham controls. PMID- 27702626 TI - Parkin elimination of mitochondria is important for maintenance of lens epithelial cell ROS levels and survival upon oxidative stress exposure. AB - Age-related cataract is associated with oxidative stress and death of lens epithelial cells (LECs) whose survival is dependent on functional mitochondrial populations. Oxidative stress-induced depolarization/damage of LEC mitochondria results in increased reactive oxygen species (ROS) levels and cell death suggesting the need for a LEC mechanism to remove mitochondria depolarized/damaged upon oxidative stress exposure to prevent ROS release and LEC death. To date, a mechanism(s) for removal of depolarized/damaged LEC mitochondria has yet to be identified and the importance of eliminating oxidative stress-damaged mitochondria to prevent LEC ROS release and death has not been established. Here, we demonstrate that Parkin levels increase in LECs exposed to H2O2-oxidative stress. We establish that Parkin translocates to LEC mitochondria depolarized upon oxidative stress exposure and that Parkin recruits p62/SQSTM1 to depolarized LEC mitochondria. We demonstrate that translocation of Parkin results in the elimination of depolarized/damaged mitochondria and that Parkin clearance of LEC mitochondria is dependent on its ubiquitin ligase activity. Importantly, we demonstrate that Parkin elimination of damaged LEC mitochondria results in reduced ROS levels and increased survival upon oxidative stress exposure. These results establish that Parkin functions to eliminate LEC mitochondria depolarized/damaged upon oxidative stress exposure and that elimination of damaged mitochondria by Parkin is important for LEC homeostasis and survival. The data also suggest that mitochondrial quality control by Parkin could play a role in lens transparency. PMID- 27702628 TI - Effects of repeated high-dose methamphetamine and ceftriaxone post-treatments on tissue content of dopamine and serotonin as well as glutamate and glutamine. AB - Repeated exposure to high doses of methamphetamine (METH) is known to alter several neurotransmitters in certain brain regions. Little is known about the effects of ceftriaxone (CEF), a beta-lactam antibiotic, known to upregulate glutamate transporter subtype 1, post-treatment on METH-induced depletion of dopamine and serotonin (5-HT) tissue content in brain reward regions. Moreover, the effects of METH and CEF post-treatment on glutamate and glutamine tissue content are not well understood. In this study, Wistar rats were used to investigate the effects of METH and CEF post-treatment on tissue content of dopamine/5-HT and glutamate/glutamine in the nucleus accumbens (NAc) and prefrontal cortex (PFC). Rats received either saline or METH (10mg/kg, i.p. every 2h*4) followed by either saline or CEF (200mg/kg, i.p, every day*3) post treatment. METH induced a significant depletion of dopamine and 5-HT in the NAc and PFC. Importantly, dopamine tissue content was completely restored in the NAc following CEF post-treatment. Additionally, METH caused a significant decrease in glutamate and glutamine tissue content in PFC, and this effect was attenuated by CEF post-treatment. These findings demonstrate for the first time the attenuating effects of CEF post-treatment on METH induced alterations in the tissue contents of dopamine, glutamate, and glutamine.

AB - In biomedical research of brain dysfunction in psychiatric disorders, utilization of animal models is essential. However, translation of findings in animal models into the realm of human clinical conditions requires reliable biomarkers that are assessed with the methods mutually employed in animal models and human patients. Near-infrared spectroscopy (NIRS) is a functional neuroimaging technique that has now been widely utilized in human basic and clinical research. However, its application to animal models has been barely conducted. In this study, we developed the method to measure neural activity in the cortex of Japanese macaques using NIRS, and examined cortical responses to presentation of a set of visual stimuli that were categorized into four different groups (flower, monkey, snake, food). Prefrontal cortical (PFC) oxy- and deoxy-hemoglobin changes were found to reliably distinguish the categories of these visual stimuli. The results suggest that cortical activity measurement with NIRS in primates can be a valuable model for identifying biomarkers associated with psychiatric disorders. PMID- 27702635 TI - Physical exercise induces hippocampal neurogenesis and prevents cognitive decline. AB - Accumulating evidence from animal and human research indicate that adult hippocampal neurogenesis plays a key role in cognition. Meanwhile, cognitive decline is well known to associate with ageing-related neurodegenerative diseases such as Alzheimer's disease (AD) and Parkinson's disease (PD). Therefore, prevention of hippocampal neurogenesis reduction should be critical for these diseases. Physical exercise, a potent enhancer of adult hippocampal neurogenesis, has emerged as a potential therapy or an adjunctive therapeutic strategy for cognitive decline. In this review, we discuss the recent findings on hippocampal neurogenesis and the incorporation of new born neurons into the neuronal network in humans and in rodents. By focusing on hippocampal neurogenesis, we illustrate the role and possible mechanisms of physical exercise in cognition preservation. PMID- 27702636 TI - Intracranial self-stimulation also facilitates learning in a visual discrimination task in the Morris water maze in rats. AB - Intracranial self-Stimulation (ICSS) of the medial forebrain bundle is a treatment capable of consistently facilitating acquisition of learning and memory in a wide array of experimental paradigms in rats. However, the evidence supporting this effect on implicit memory comes mainly from classical conditioning and avoidance tasks. The present work aims to determine whether ICSS would also improve the performance of rats in another type of implicit task such as cued simultaneous visual discrimination in the Morris Water Maze. The ICSS treatment was administered immediately after each of the five acquisition sessions and its effects on retention and reversal were evaluated 72h later. Results showed that ICSS subjects committed fewer errors than Sham subjects and adopted more accurate trajectories during the acquisition of the task. This improvement was maintained until the probe test at 72h. However, ICSS animals experienced more difficulties than the Sham group during the reversal of the same learning, reflecting an impairment in cognitive flexibility. We conclude that post-training ICSS could also be an effective treatment for improving implicit visual discrimination learning and memory. PMID- 27702637 TI - Aging process alters hippocampal and cortical secretase activities of Wistar rats. AB - A growing body of evidence has demonstrated amyloid plaques in aged brain; however, little attention has been given to amyloid precursor protein (APP) processing machinery during the healthy aging process. The amyloidogenic and non amyloidogenic pathways, represented respectively by beta- and alpha-secretases (BACE and TACE), are responsible for APP cleavage. Our working hypothesis is that the normal aging process could imbalance amyloidogenic and non-amyloidogenic pathways specifically BACE and TACE activities. Besides, although it has been showed that exercise can modulate secretase activities in Alzheimer Disease models the relationship between exercise effects and APP processing during healthy aging process is rarely studied. Our aim was to investigate the aging process and the exercise effects on cortical and hippocampal BACE and TACE activities and aversive memory performance. Young adult and aged Wistar rats were subjected to an exercise protocol (20min/day for 2 weeks) and to inhibitory avoidance task. Biochemical parameters were evaluated 1h and 18h after the last exercise session in order to verify transitory and delayed exercise effects. Aged rats exhibited impaired aversive memory and diminished cortical TACE activity. Moreover, an imbalance between TACE and BACE activities in favor of BACE activity was observed in aged brain. Moderate treadmill exercise was unable to alter secretase activities in any brain areas or time points evaluated. Our results suggest that aging-related aversive memory decline is partly linked to decreased cortical TACE activity. Additionally, an imbalance between secretase activities can be related to the higher vulnerability to neurodegenerative diseases induced by aging. PMID- 27702638 TI - Application of various control strategies to Japanese encephalitic: A mathematical study with human, pig and mosquito. AB - Japanese encephalitis (JE) is a public health problem that threats the entire world today. Japanese Encephalitis virus (JEV) mostly became a threat due to the significant number of increase of susceptible mosquito vectors and vertebrate hosts in Asia by which around 70,000 cases and 10,000 deaths per year took place in children below 15 years of age. In this paper, a mathematical model of JE due to JEV from the vector source (infected mosquito) and two vertebrate hosts (infected human and infected pig) is formulated. The disease can be controlled by applying several control measures such as vaccination, medicine and insecticide to the JE infection causing species. The model has been formulated as an optimal control problem and has been solved using Pontryagin's maximum principle.

PMID- 27702639 TI - The influence of walkability on broader mobility for Canadian middle aged and older adults: An examination of Walk ScoreTM and the Mobility Over Varied Environments Scale (MOVES). AB - Neighborhood built environments may play an important role in shaping mobility and subsequent health outcomes. However, little work includes broader mobility considerations such as cognitive ability to be mobile, social connections with community, or transportation choices. We used a population-based sample of Canadian middle aged and older adults (aged 45 and older) from the Canadian Community Health Survey-Healthy Aging (CCHS-HA, 2008-2009) to create a holistic mobility measure: Mobility over Varied Environments Scale (MOVES). Data from CCHS HA respondents from British Columbia with MOVES were linked with Street Smart Walk ScoreTM data by postal code (n=2046). Mean MOVES was estimated across sociodemographic and health characteristics. Linear regression, adjusted for relevant covariates, was used to estimate the association between Street Smart Walk ScoreTM and the MOVES. The mean MOVES was 30.67 (95% confidence interval (CI) 30.36, 30.99), 5th percentile 23.27 (CI 22.16, 24.38) and 95th percentile was 36.93 (CI 35.98, 37.87). MOVES was higher for those who were younger, married, higher socioeconomic status, and had better health. In unadjusted models, for every 10 point increase in Street Smart Walk ScoreTM, MOVES increased 4.84 points (CI 4.52, 5.15). However, results attenuated after adjustment for sociodemographic covariates: each 10 point increase in Street Smart Walk ScoreTM was associated with a 0.10 (CI 0.00, 0.20) point increase in MOVES. The modest but important link we observed between walkability and mobility highlights the implication of neighborhood design on the health of middle aged and older adults.

PMID- 27702643 TI - Electroencephalographic correlates of states of concentrative meditation. AB - Meditative techniques aim for and meditators report states of mental alertness and focus, concurrent with physical and emotional calm. We aimed to determine the electroencephalographic (EEG) correlates of five states of Buddhist concentrative meditation, particularly addressing a correlation with meditative level. We studied 12 meditators and 12 pair-matched meditation-naive participants using high-resolution scalp-recorded EEG. To maximise reduction of EMG, data were pre processed using independent component analysis and surface Laplacian transformed data. Two non-meditative and five meditative states were used: resting baseline, mind-wandering, absorptions 1, 2, 3, 4 and 5 (corresponding to four levels of absorption and an absorption with a different object of focus, otherwise equivalent to level 4; these five meditative states produce repeatable, distinctly different experiences for experienced meditators). The experimental protocol required participants to experience the states in the order listed above, followed immediately by the reverse. We then calculated EEG power in standard frequency bands from 1 to 80Hz. We observed decreases of central scalp beta (13-25Hz), and central low gamma (25-48Hz) power in meditators during deeper absorptions. In contrast, we identified increases in frontal midline and temporo parietal theta power in meditators, again, during deeper absorptions. Alpha activity was increased over all meditative states, not depth-related. This study demonstrates that the subjective experiences of deepening meditation partially correspond to measures of EEG. Our results are in accord with prior studies on non-graded meditative states. These results are also consistent with increased theta correlating with tightness of focus, and reduced beta/gamma with the desynchronization associated with enhanced alertness. PMID- 27702644 TI - Making sense of what you sense: Disentangling interoceptive awareness, sensibility and accuracy. AB - Garfinkel and Critchley (2013) recently proposed a three level model of interoception. Only few studies, however, have empirically tested this theoretical model thus far. The present study aimed at investigating (1) the central assumptions of this model, i.e. that Accuracy, Sensibility and Awareness are distinguishable facets of interoception and that Interoceptive Accuracy is the basic level of interoception, and (2) whether cardiovascular activation (as indexed by heart rate) is differentially related to the three facets of interoception. Analyses were conducted on a total sample of N=159 healthy participants (118 female [74.2%]; mean age=23.9years, SD=3.3, range=19-45) who performed either the heartbeat tracking task, the heartbeat discrimination task or both. The results suggest that Accuracy, Sensibility and Awareness are empirically distinct facets of interoception, showing no correlation when based on heartbeat tracking, but moderate correlations when based on heartbeat discrimination. The assumption that Interoceptive Accuracy is the basic level of interoception could only be partially confirmed. Instead, we conclude that the level of objective physiological states should be considered as the most basic level of interoceptive signal processing. PMID- 27702646 TI - Sensory responses in the medial prefrontal cortex of anesthetized rats. Implications for sensory processing. AB - The medial prefrontal cortex (mPFC) plays a key role in higher functions such as memory and attention. In order to demonstrate sensory responses in the mPFC, we used electrophysiological recordings of urethane-anesthetized rats to record somatosensory-evoked potentials (SEPs) or auditory-evoked potentials (AEPs) elicited by whisker deflections and click stimulation, respectively. Contralateral whisker stimulation or auditory stimuli were also applied to study sensory interference in the mPFC. Interference with other sensory stimuli or recent stimulation history reduced whisker responses in the infralimbic and prelimbic cortices of the ventral mPFC. This effect could be mediated by activation of parvalbumin (PV) interneurons since the effect was blocked by the P/Q calcium channel antagonist omega-agatoxin. In contrast, sensory interference or the recent stimulation history was not detected by the dorsal mPFC or the primary somatosensory cortex. Results obtained from retrograde tracer injections in the dorsal and ventral regions of the mPFC indicated that somatosensory and auditory sensory inputs may arrive at the dorsal mPFC through secondary sensory cortical areas, and through the insular and temporal cortical areas. The ventral mPFC may receive sensory information through the strong anatomical connections between the dorsal and ventral mPFC areas. In conclusion, results suggest mPFC plays an important role in sensory processing, which may have important implications in attentional and memory processes. PMID- 27702645 TI - Timing of amphetamine exposure in relation to puberty onset determines its effects on anhedonia, exploratory behavior, and dopamine D1 receptor expression in young adulthood. AB - Non-medical use of amphetamine (AMPH) among adolescents is prevalent, which is problematic given the potential consequences of developmental drug exposure on brain function and behavior. Previously we found in adult male rats that AMPH exposure starting before puberty induces a persistent decrease in dopamine D1 receptor (D1R) function in the medial prefrontal cortex (mPFC). Here we investigated if this dysfunction was associated with changes in D1R expression in the mPFC and nucleus accumbens (NAc). We also determined if starting drug exposure well before or near the onset of puberty would influence AMPH-induced changes in D1R expression and behavior. Male and female Sprague-Dawley rats were treated once every other day (10 injections total) with saline or 3mg/kg AMPH (i.p.) from either postnatal day (P) 27 to 45 (pre-puberty groups; Pre-P) or P37 to 55 (peri-puberty groups; Peri-P). After 1, 7 and 21days of withdrawal, sucrose preference tests were performed to assess anhedonia. Exploratory behavior was studied in an open-field arena and on an elevated plus maze (EPM). Rats were then sacrificed for Western blot analysis of D1R expression. We found that AMPH withdrawal induced decreases in sucrose preference that persisted in rats with Peri-P onset treatment. Pre-P onset AMPH exposure led to increased open-arm exploration in the EPM test, as well as a decreased D1R level in the mPFC but not NAc. Our results demonstrated that AMPH exposure starting at different developmental stages resulted in distinct neurobehavioral abnormalities, suggesting an important role of exposure timing in drug-induced plasticity. PMID- 27702648 TI - Probing pain pathways with light. AB - We have witnessed an accelerated growth of photonics technologies in recent years to enable not only monitoring the activity of specific neurons, while animals are performing certain types of behavior, but also testing whether specific cells, circuits, and regions are sufficient or necessary for initiating, maintaining, or altering this or that behavior. Compared to other sensory systems, however, such as the visual or olfactory system, photonics applications in pain research are only beginning to emerge. One reason pain studies have lagged behind is that many of the techniques originally developed cannot be directly implemented to study key relay sites within pain pathways, such as the skin, dorsal root ganglia, spinal cord, and brainstem. This is due, in part, to difficulties in accessing these structures with light. Here we review a number of recent advances in design and delivery of light-sensitive molecular probes (sensors and actuators) into pain relay circuits to help decipher their structural and functional organization. We then discuss several challenges that have hampered hardware access to specific structures including light scattering, tissue movement and geometries. We review a number of strategies to circumvent these challenges, by delivering light into, and collecting it from the different key sites to unravel how nociceptive signals are encoded at each level of the neuraxis. We conclude with an outlook on novel imaging modalities for label-free chemical detection and opportunities for multimodal interrogation in vivo. While many challenges remain, these advances offer unprecedented opportunities to bridge cellular approaches with context-relevant behavioral testing, an essential step toward improving translation of basic research findings into clinical applications. PMID- 27702647 TI - Effect of acute lateral hemisection of the spinal cord on spinal neurons of postural networks. AB - In quadrupeds, acute lateral hemisection of the spinal cord (LHS) severely impairs postural functions, which recover over time. Postural limb reflexes (PLRs) represent a substantial component of postural corrections in intact animals. The aim of the present study was to characterize the effects of acute LHS on two populations of spinal neurons (F and E) mediating PLRs. For this purpose, in decerebrate rabbits, responses of individual neurons from L5 to stimulation causing PLRs were recorded before and during reversible LHS (caused by temporal cold block of signal transmission in lateral spinal pathways at L1), as well as after acute surgical LHS at L1. Results obtained after Sur-LHS were compared to control data obtained in our previous study. We found that acute LHS caused disappearance of PLRs on the affected side. It also changed a proportion of different types of neurons on that side. A significant decrease and increase in the proportion of F- and non-modulated neurons, respectively, was found. LHS caused a significant decrease in most parameters of activity in F-neurons located in the ventral horn on the lesioned side and in E-neurons of the dorsal horn on both sides. These changes were caused by a significant decrease in the efficacy of posture-related sensory input from the ipsilateral limb to F-neurons, and from the contralateral limb to both F- and E-neurons. These distortions in operation of postural networks underlie the impairment of postural control after acute LHS, and represent a starting point for the subsequent recovery of postural functions. PMID- 27702649 TI - A complete mitochondrial genome from Echinochasmus japonicus supports the elevation of Echinochasminae Odhner, 1910 to family rank (Trematoda: Platyhelminthes). AB - The complete mitochondrial (mt) genome of the trematode Echinochasmus japonicus Tanabe, 1926 was fully determined and annotated. The circular mt molecule of this species is 15,865bp in length, containing 12 protein-coding genes (arranged in the following order: cox3-cob-nad4L-nad4-atp6-nad2-nad1-nad3-cox1-cox2-nad6 nad5), two ribosomal RNA genes (rrnL and rrnS) and 22 transfer RNA genes (trnH; trnQ; trnF; trnM; trnV; trnA; trnD; trnN; trnP; trnI; trnK; trnS1(AGN); trnW; trnT; trnC; trnL1(CUN); trnS2(UCN); trnL2(UUN); trnG; and trnE). The atp8 gene is absent. The 3' end of nad4L overlaps the 5' end of nad4 by 40bp. An array of eight identical tandem repeats (240bp each) was found between trnG and trnE in the long non-coding region of the individual worm sequenced. Numbers of these repeats varied among E. japonicus samples. Phylogenetic analysis of concatenated mt protein sequences of 40 trematode species/strains supports the elevation of Echinochasminae Odhner, 1910 to family rank, close to the families Echinostomatidae and Fasciolidae. As echinochasmid and echinostomatid species can parasitize humans, the future characterization of additional mt genomes is needed for development of mt markers for identification and phylogenetic, population, epidemiological and hybridization studies. PMID- 27702650 TI - Central leptin action on euglycemia restoration in type 1 diabetes: Restraining responses normally induced by fasting? AB - Leptin monotherapy is sufficient to restore euglycemia in insulinopenic type 1 diabetes (T1D), yet the underlying mechanism remains poorly understood. Accumulating evidence demonstrates that the brain mediates the leptin action on euglycemia restoration. Here, we first review evidence supporting that symptoms in T1D resemble an uncontrolled response to fasting. Then, we discuss recent research progress on brain neurons and their neurotransmitters that potentially mediate the leptin action. Finally, peripheral effective pathways, which are normally involved in fasting responses and associated with leptin action on euglycemia restoration in T1D, will also be discussed. This summary complements several previous excellent reviews on this topic (Meek and Morton, 2016; Perry et al., 2016; Fujikawa and Coppari, 2015). A deep understanding of neurocircuitry and the peripheral effective pathways that mediate the leptin action on euglycemia restoration will likely lead to novel targets for an insulin independent therapeutics against T1D. PMID- 27702652 TI - Prolyl hydroxylase domain enzymes and their role in cell signaling and cancer metabolism. AB - The prolyl hydroxylase domain (PHD) enzymes regulate the stability of the hypoxia inducible factor (HIF) in response to oxygen availability. During oxygen limitation, the inhibition of PHD permits the stabilization of HIF, allowing the cellular adaptation to hypoxia. This adaptation is especially important for solid tumors, which are often exposed to a hypoxic environment. However, and despite their original role as the oxygen sensors of the cell, PHD are currently known to display HIF-independent and hydroxylase-independent functions in the control of different cellular pathways, including mTOR pathway, NF-kB pathway, apoptosis and cellular metabolism. In this review, we summarize the recent advances in the regulation and functions of PHD in cancer signaling and cell metabolism. PMID- 27702653 TI - UCN enhances TGF-beta-mediated mitoinhibition of VSMCs via counteracting TGF-beta induced cPLA2 expression and activation. AB - Urocortins (UCNs) and transforming growth factor-beta (TGF-beta) have been demonstrated to participate in various cardiovascular diseases, many of which involve vascular smooth muscle cells (VSMCs) proliferation. Cytosolic phospholipase A2 (cPLA2)-mediated arachidonic acid (AA) release is an important cause of VSMCs proliferation. The work was to investigate the regulation of VSMCs proliferation by UCN/TGF-beta and whether cPLA2 was a link between their signaling pathways. VSMCs proliferation was measured by colorimetric assay and immunofluorescence microscopy. Using cell flow cytometry, the changes in the cell cycle phases were investigated. Lentiviral Vector Particle was performed to overexpress cPLA2 gene. Both UCN and TGF-beta inhibited VSMCs proliferation and an additive effect was observed when the cells were treated with UCN plus TGF beta. TGF-beta increased the percentage of cells in G1-phase while UCN increased the cell percentage in G2-phase with a concomitant decrease in S-phase. Furthermore, cPLA2 expression was increased by TGF-beta but decreased by UCN and UCN attenuated TGF-beta-induced cPLA2 expression. In primary VSMCs, TGF-beta induced cPLA2 phosphorylation, and this effect was also attenuated by UCN. Similar to UCN, the cPLA2 inhibitor, pyrrophenone (PYR), also played a role in enhancing TGF-beta-mediated mitoinhibition. Inversely, overexpression of cPLA2 eliminated the effect of UCN on the mitoinhibition. The pretreatment with UCN counteracted TGF-beta-mediated cPLA2 expression and activation, thereby contributing to TGF-beta-mediated mitoinhibition of VSMCs. PMID- 27702651 TI - Phosphorylation of MITF by AKT affects its downstream targets and causes TP53 dependent cell senescence. AB - Microphthalmia-associated transcription factor (MITF) plays a crucial role in the melanogenesis and proliferation of melanocytes that is dependent on its abundance and modification. Here, we report that epidermal growth factor (EGF) induces senescence and cyclin-dependent kinase inhibitor 1A (CDKN1A) expression that is related to MITF. We found that MITF could bind TP53 to regulate CDKN1A. Furthermore, the interaction between MITF and TP53 is dependent on AKT activity. We found that AKT phosphorylates MITF at S510. Phosphorylated MITF S510 enhances its affinity to TP53 and promotes CDKN1A expression. Meanwhile, the unphosphorylative MITF promotes TYR expression. The levels of p-MITF-S510 are low in 90% human melanoma samples. Thus the level of p-MITF-S510 could be a possible diagnostic marker for melanoma. Our findings reveal a mechanism for regulating MITF functions in response to EGF stimulation and suggest a possible implementation for preventing the over proliferation of melanoma cells. PMID- 27702654 TI - Bone morphogenetic protein 2 promotes osteogenesis of bone marrow stromal cells in type 2 diabetic rats via the Wnt signaling pathway. AB - Type 2 diabetes mellitus impairs osteogenesis in bone marrow stromal cells (BMSCs). Bone morphogenetic protein 2 (BMP2) has been extensively applied for bone defect restoration and has been shown to activate the Wnt signaling pathway. The objective of this study was to investigate the effects of BMP2 on the cell proliferation and osteogenesis of type 2 diabetic BMSCs in rats and explore whether BMP2 induced osteogenesis via the stimulation of Wnt signaling pathway. The cell experiments were divided into DM (diabetic BMSCs), BMP25 (induced with 25ng/ml BMP2), BMP100 (induced with 100ng/ml BMP2) and BMP25 +XAV groups. All cells with or without the different concentrations of BMP2 were cultured under the same experimental conditions. The in vitro results indicated that BMP2 enhanced cell proliferation by 130%-157% and osteogenic differentiation by approximately two-fold in type 2 diabetic BMSCs. The expression levels of beta catenin, cyclin D1, Runx2 and c-myc related to the Wnt signaling pathway were also upregulated from 180% to 212% in BMP2-induced type 2 diabetic rat BMSCs, while the level of GSK3beta decreased to 43%. In BMP2-induced type 2 diabetic BMSCs with calcium phosphate cement (CPC) scaffolds for osteoblast study in vivo, the appearance of newly formed bone dramatically increased to 175% compared with type 2 diabetic BMSCs. These data demonstrated that BMP2 enhanced bone regeneration in diabetic BMSCs by stimulating the Wnt signaling pathway with the accumulation of beta-catenin and the depressed expression of GSK3beta. Diabetic BMSCs associated with BMP2 might be a potential tissue-engineered construct for bone defects in type 2 diabetes mellitus. PMID- 27702656 TI - A framework to establish credibility of computational models in biology. AB - Computational models in biology and biomedical science are often constructed to aid people's understanding of phenomena or to inform decisions with socioeconomic consequences. Model credibility is the willingness of people to trust a model's predictions and is often difficult to establish for computational biology models. A 3 * 3 matrix has been proposed to allow such models to be categorised with respect to their testability and epistemic foundation in order to guide the selection of an appropriate process of validation to supply evidence to establish credibility. Three approaches to validation are identified that can be deployed depending on whether a model is deemed untestable, testable or lies somewhere in between. In the latter two cases, the validation process involves the quantification of uncertainty which is a key output. The issues arising due to the complexity and inherent variability of biological systems are discussed and the creation of 'digital twins' proposed as a means to alleviate the issues and provide a more robust, transparent and traceable route to model credibility and acceptance. PMID- 27702657 TI - PH-sensitive bionanocomposite hydrogel beads based on carboxymethyl cellulose/ZnO nanoparticle as drug carrier. AB - The present work explains the preparation of new pH-sensitive bionanocomposite beads based on carboxymethyl cellulose (CMC) and ZnO nanoparticles for use as controlled release drug delivery systems. Fe3+ ion as physical crosslinking agent was used to prepare ionic cross-linked bionanocomposite hydrogel beads. Propranolol hydrochloride (PPN) has been chosen as a model drug. Characterization of the pH-sensitive bionanocomposite beads resulting from incorporation of different content of ZnO nanoparticles into CMC matric was carried out using different experimental techniques: XRD, FT-IR, TGA, SEM and EDX. Propranolol incorporation efficiency in beads was determined by UV-vis spectroscopy and was found to be high. Moreover, the swelling and drug release properties of the bionanocomposite hydrogels were investigated. The prepared bionanocomposite beads showed a pH sensitive swelling behavior with maximum water absorbing at pH 7.4. Also, it was found that the swelling ratio of ZnO/CMC hydrogels in different aqueous solutions was rather higher in comparison with its neat hydrogel. In vitro drug release test was carried out to prove the effectiveness of this novel type of bionanocomposite hydrogel beads as a controlled drug delivery system. A more sustained and controlled drug releases were observed for ZnONPs containing NaCMC beads, which increased by the increase in ZnONPs content. PMID- 27702658 TI - Inhibition of lysozyme fibrillation by human serum albumin nanoparticles: Possible mechanism. AB - Amyloid fibrillation is a prevalent phenomenon in different proteins and peptides, which results in a variety of disorders. Over the last decade, implementation of nanoparticles (NPs), with or without drugs, is considered as a promising approach to protect against the aggregation process of amyloid proteins. In this study, we investigated the effect of human serum albumin NPs (HSA NPs) on the fibrillation of Hen Egg White Lysozyme (HEWL). The results showed that HSA NPs decrease the fibrillation of HEWL in a size dependent manner. Surprisingly, despite their inhibitory effects on the formation of long fibrils, our studies revealed that the NPs do not preserve the stability of the protein's structure in denaturing conditions. In fact, different structural analysis methods revealed that in the presence of the NPs, the protein's tendency to expose hydrophobic patches increased. Therefore, it seems that HSA NPs are responsible for decrease in HEWL fibrillation by reducing its concentration and blocking hot spot regions for self-assembly via moderate interaction. Collectively, our results shed light on the impact of HSA NPs on HEWL fibrillation and open new challenges on the implications of these NPs for drug delivery purposes or direct use as therapeutic agents. PMID- 27702659 TI - Study of the UV protective and antibacterial properties of aqueous polyurethane dispersions extended with low molecular weight chitosan. AB - A series of aqueous dispersions of polyurethane (PU) and low molecular weight chitosan (CS(LMW)) has been prepared in two steps synthetic process. In first step PU prepolymer, with NCO termini were prepared by reacting isophrone diisocyanate (IPDI), poly (caprolactone) diol (CAPA, Mn 1000), and 2,2-dimethylol propionic acid (DMPA), followed by neutralization of PU prepolymer with triethylamine (TEA). In second step PU prepolymer chain was extended by low molecular weight chitosan followed by dispersion formation by adding calculated volume of water. Molecular characterization of CS(LMW)-PU finishes was done by FTIR and application on poly-cotton blended fabric samples was confirmed by scanning electron microscopy (SEM). Antimicrobial and UV protective performance of treated fabrics was performed by AATCC 100 and AATCC TM183 methods respectively. Furthermore, it shows that the addition of chitosan remarkably increases antimicrobial and UV protective properties of PUs. PMID- 27702660 TI - Vasohibin 2 promotes human luminal breast cancer angiogenesis in a non-paracrine manner via transcriptional activation of fibroblast growth factor 2. AB - Vasohibin 2 (VASH2) is an angiogenic factor and cancer-related protein that acts via paracrine mechanisms. Here, we investigated the angiogenic function and mechanism of action of VASH2 in 200 human breast cancer tissues by performing immunohistochemical staining, western blot, indirect sandwich enzyme-linked immunosorbent assay (ELISA), and a semi-quantitative sandwich-based antibody array. Breast cancer cells stably overexpressing VASH2 or with knocked-down VASH2 were established and used for in vivo and in vitro models. In human luminal tissue, but not in HER2-positive or basal-like breast cancer tissues, VASH2 was positively correlated with CD31-positive microvascular density, induced angiogenesis in xenograft tumors, and promoted human umbilical vein endothelial cell tube formation in vitro. VASH2 expression was absent in the concentrated conditioned medium collected from knocked-down VASH2 and VASH2-overexpressing luminal breast cancer cells. Further, VASH2 regulated the expression of fibroblast growth factor 2 (FGF2) in human luminal breast cancer cells, and the pro-angiogenic effect induced by VASH2 overexpression was blocked by FGF2 neutralization in vitro. Additionally, dual luciferase reporter assay and Chromatin immunoprecipitation analysis results showed that FGF2 promoter was transcriptionally activated by VASH2 via histone modifications. In conclusion, VASH2 expression is positively correlated with FGF2 expression and promotes angiogenesis in human luminal breast cancer by transcriptional activation of fibroblast growth factor 2 through non-paracrine mechanisms. PMID- 27702661 TI - Osteopontin induces autophagy to promote chemo-resistance in human hepatocellular carcinoma cells. AB - Hepatocellular carcinoma (HCC) is a major health burden worldwide for its high incidence and mortality. Osteopontin (OPN) is a chemokine-like, matricellular phosphoglycoprotein whose expression is elevated in various types of cancer including HCC. OPN has been shown to be involved in tumorigenesis, chemo resistance, metastasis and sustaining stem-like properties of cancer cells. Autophagy is a cellular process by which cytoplasmic components are degraded and recycled for maintaining cellular homeostasis. There is increasing evidence supports that autophagy plays a critical role for stem-like properties and chemo resistance of cancer cells. However, the relationship between OPN and autophagy in maintaining cancer stem-like properties and chemo-resistance is yet to be clarified. Herein, we found that secreted OPN induced autophagy via binding with its receptor integrin alphavbeta3 and sustaining FoxO3a stability. OPN-elicited autophagy could promote cancer cell survival and resistance to chemotherapy drugs, as well as stem-like properties. Our findings indicated that OPN was capable of promoting chemo-resistance of HCCs via autophagy, which might provide a new strategy for the treatment of HCC. PMID- 27702655 TI - Transmural gradients in ion channel and auxiliary subunit expression. AB - Evolution has acted to shape the action potential in different regions of the heart in order to produce a maximally stable and efficient pump. This has been achieved by creating regional differences in ion channel expression levels within the heart as well as differences between equivalent cardiac tissues in different species. These region- and species-dependent differences in channel expression are established by regulatory evolution, evolution of the regulatory mechanisms that control channel expression levels. Ion channel auxiliary subunits are obvious targets for regulatory evolution, in order to change channel expression levels and/or modify channel function. This review focuses on the transmural gradients of ion channel expression in the heart and the role that regulation of auxiliary subunit expression plays in generating and shaping these gradients. PMID- 27702662 TI - Upregulation of SNHG6 regulates ZEB1 expression by competitively binding miR-101 3p and interacting with UPF1 in hepatocellular carcinoma. AB - Emerging evidence suggests that small nucleolar RNAs (snoRNAs) and their host genes (SNHGs) have malfunctioning roles in the development of human cancers. We globally investigated the molecular mechanisms by which snoRNA host gene 6 (SNHG6) promotes hepatocellular carcinoma (HCC) progression using human tissues and cell lines. We found that SNHG6 is overexpressed in HCC tissues and in hepatoma cell lines and is closely associated with histologic grade, hepatitis B virus DNA, Barcelona Clinic Liver Cancer stage and portal vein tumor thrombus in patients with HCC. Knockdown of SNHG6 induced apoptosis and repressed cell cycle progression in hepatoma cell lines, whereas transgenic expression of SNHG6 in the immortalized human hepatic cell line L02 had opposite effects. Xenograft tumors grown from SNHG6-knockdown cells had smaller mean volumes than did tumors grown from control cells. SNHG6 may act as a competing endogenous RNA, effectively becoming a sink for miR-101-3p and thereby modulating the derepression of zinc finger E-box binding homeobox 1, imposing an additional level of post transcriptional regulation. Functionally, SNHG6 promotes tumor growth and metastasis by inducing epithelial to mesenchymal transition. Further investigations showed that SNHG6 could affect HCC tumorigenesis by binding to up frameshift protein 1 and regulating Smad7 expression. PMID- 27702663 TI - Evaluation of the cytotoxic and genotoxic effects of benchmark multi-walled carbon nanotubes in relation to their physicochemical properties. AB - To contribute with scientific evidence to the grouping strategy for the safety assessment of multi-walled carbon nanotubes (MWCNTs), this work describes the investigation of the cytotoxic and genotoxic effects of four benchmark MWCNTs in relation to their physicochemical characteristics, using two types of human respiratory cells. The cytotoxic effects were analysed using the clonogenic assay and replication index determination. A 48h-exposure of cells revealed that NM-401 was the only cytotoxic MWCNT in both cell lines, but after 8-days exposure, the clonogenic assay in A549 cells showed cytotoxic effects for all the tested MWCNTs. Correlation analysis suggested an association between the MWCNTs size in cell culture medium and cytotoxicity. No induction of DNA damage was observed after any MWCNTs in any cell line by the comet assay, while the micronucleus assay revealed that both NM-401 and NM-402 were genotoxic in A549 cells. NM-401 and NM-402 are the two longest MWCNTs analyzed in this work, suggesting that length may be determinant for genotoxicity. No induction of micronuclei was observed in BBEAS-2Beas-2B cell line and the different effect in both cell lines is explained in view of the size-distribution of MWCNTs in the cell culture medium, rather than cell's specificities. PMID- 27702664 TI - Impact of R264C and R264H polymorphisms in human aromatase function. AB - The cytochrome P450 aromatase is involved in the last step of sex hormones biosynthesis by converting androgens into estrogens. The human enzyme is highly polymorphic and literature data correlate aromatase single nucleotide polymorphisms to the onset of pathologies such as breast cancer and neurodegenerative diseases. The aims of this study were i) to study the influence of the mutations R264C and R264H on the structure-function of the enzyme also upon phosphorylation by selected kinases and ii) to compare the activity of the variants to that of aromatase wild type in two different cell lines. Far-UV circular dichroism spectroscopy, thermal denaturation experiments and CO-binding assay showed that the two polymorphic variants are correctly folded. Steady-state kinetics experiments showed that rArom R264C and R264H exhibit a 1.5 and 3.4 folds lower catalytic efficiency, respectively, when compared to the wild type protein. Since R264 is part of the consensus motif of PKA and PKG1, phosphorylation experiments were performed to study the effect on aromatase function. Phosphorylation by PKA caused a decrease in activity by 36.2%, 49.3% and 27.9% in the wild type, R264C and R264H proteins respectively. Phosphorylation by PKG1 was also found to decrease the activity by 30.3%, 30.5% and 15.4% in the wild type, R264C and R264H proteins respectively. Experiments performed on the three full-length proteins expressed in human MCF-7 breast cancer cells and rat ST14A neuronal cells showed that, depending on the cell line used, the activity of the proteins is different, implicating different cellular mechanisms modulating aromatase activity. This work demonstrate that R264 polymorphism causes an intrinsic alteration of aromatase activity together with a different consensus for phosphorylation by different kinases, indicating that estrogen production can be different when such mutations are present. These findings are significant in understanding the onset and treatment of pathologies in which aromatase has been shown to be involved.

AB - A new acetophenone, 2,4,6-trihydroxy-3-methylacetophenone-2-O-beta-d-glucoside (1), together with 21 known compounds; one acetophenone (2), four chromone glycosides (3-6), six phenylpropanoids (7-12), six sesquiterpenoids (13-18), two triterpenoids (19 and 20), one sterol (21), and one tannin (22) were isolated from the flower buds of Syzygium aromaticum (cloves). The structure of the new compound 1 was determined by spectroscopic analyses including 1D-, 2D-NMR and HRMS interpretation. Among the isolates, one acetophenone (2), three phenylpropanoids (10-12), and one sesquiterpenoid (13) were isolated from the flower buds of S. aromaticum for the first time in this study. All the isolates (1-22) were evaluated for their cytotoxicity against human ovarian cancer cells (A2780) using MTT assays. Some of the isolates (5, 6, 9, 15, 17, 19, 20, and 21) showed either moderate or weak cytotoxicity on A2780 cells.

AB - White Mulberry Root-bark (WMR) is an edible Chinese herbal used for the treatment of inflammation, nephritis and asthma. This study aimed to investigate the inhibitory effects of ethanol extract from WMR against human carboxylesterase 2 (hCE2), as well as to identity and character natural hCE2 inhibitors in this herbal. Our results demonstrated that the ethanol extract of WMR displayed potent inhibitory effects against hCE2, while three major bioactive constitutes in WMR were identified on the basis of LC fingerprinting combined with activity-based screening of LC fractions. Three bioactive compounds including SD, KG and SC were efficiently identified by comparison of LC retention times, UV and MS spectral data, with the help of authentic standards. The inhibition potentials and inhibition types of these natural compounds against hCE2 were further investigated in human liver microsomes. The results demonstrated that these bioactive compounds are potent non-competitive inhibitors against hCE2, with the Ki values ranging from 0.76MUM to 1.09MUM. All these findings suggested that three abundant natural compounds in WMR displayed potent inhibitory effects against hCE2, which could be used as lead compounds to develop more potent hCE2 inhibitors for the alleviation of hCE2-mediated severe delayed-onset diarrhea.

AB - The main objective of this project was to investigate the antibacterial activity of 19 species (Juncus acutus, J. alpinoarticulatus, J. articulatus, J. compressus, J. conglomeratus, J. effusus, J. filiformis, J. gerardii, J. inflexus, J. maritimus, J. monanthos, J. squarrosus, J. tenuis, J. trifidus, Luzula campestris, L. forsteri, L. luzuloides, L. sudetica and L. sylvatica) belonging to the family Juncaceae against methicillin-resistant S. aureus (MRSA), extended-spectrum beta-lactamase (ESBL)-producing C. freundii, E. coli, E. cloacae, K. pneumoniae, and multiresistant A. baumannii and P. aeruginosa. Antibacterial susceptibilities were screened for inhibitory zones and MIC values determined by microdilution method. Among the tested extracts (n=96) 16 extracts prepared from Juncus species and 3 extracts from Luzula species showed mild to strong inhibitory activities against MRSA strains (inhibition zones=6.7mm-14.6mm; MIC values 9.75-156MUg/mL). It can be concluded that Juncus and Luzula species demonstrated promising anti-MRSA effect, and J. maritimus, J. tenuis and J. gerardii considered worthy of activity-guided phytochemical investigations. The main bioactive constituents of Juncaceae species are phenanthrenes. Four phenanthrenes [juncuenin D (1), juncusol (2), dehydrojuncuenin B (3), and jinflexin B (4)] isolated previously from J. inflexus with anti-MRSA activity were investigated by LC-MS in extracts proved to be active in antimicrobial test.

PMID- 27702668 TI - Influence of xanthotoxin (8-methoxypsoralen) on the anticonvulsant activity of various novel antiepileptic drugs against maximal electroshock-induced seizures in mice. AB - The aim of this study was to determine the effects of xanthotoxin (8 methoxypsoralen) on the protective action of 5 various second- and third generation antiepileptic drugs (i.e., lacosamide, lamotrigine, oxcarbazepine, pregabalin and topiramate) in the mouse maximal electroshock-induced seizure model. Seizure activity was evoked in adult male albino Swiss mice by a current (25mA, 500V, 0.2s stimulus duration) delivered via auricular electrodes. Drug related adverse effects were determined in the chimney, grip-strength and passive avoidance tests. Total brain antiepileptic drug concentrations were measured to confirm pharmacodynamic nature of observed interactions with xanthotoxin. Results indicate that xanthotoxin (100mg/kg, i.p.) significantly enhanced the anticonvulsant action of lacosamide (P<0.01), oxcarbazepine (P<0.05), pregabalin (P<0.01), and topiramate (P<0.001), but not that of lamotrigine in the maximal electroshock-induced seizure test. Moreover, xanthotoxin (50mg/kg) still significantly potentiated the anticonvulsant action of lacosamide (P<0.05), pregabalin (P<0.05), and topiramate (P<0.001) in this seizure test. Xanthotoxin had no significant impact on total brain concentrations of the studied antiepileptic drugs in mice. Furthermore, combinations of xanthotoxin with oxcarbazepine or topiramate produced no adverse effects. However, xanthotoxin in combination with lacosamide, lamotrigine or pregabalin significantly reduced muscular strength in mice in the grip-strength test. In the chimney test, only the combinations of xanthotoxin with pregabalin significantly impaired motor coordination in mice. In conclusion, the combinations of xanthotoxin with oxcarbazepine and topiramate produce beneficial anticonvulsant pharmacodynamic interactions in the maximal electroshock-induced seizure test. A special caution is advised when combining xanthotoxin with pregabalin due to appearance of acute adverse effects. PMID- 27702670 TI - Mammalian target of rapamycin inhibition counterbalances the inflammatory status of immune cells in patients with chronic granulomatous disease. AB - BACKGROUND: Chronic granulomatous disease (CGD) is a primary immunodeficiency caused by defective production of reactive oxygen species in phagocytic cells that results in life-threatening infections and severe inflammatory manifestations. The treatment of inflammatory manifestations remains challenging because it can be associated with an increased risk of infections. Previous studies have shown that phagocytes from patients with CGD display a defect in autophagy and a reactive oxygen species-independent activation of the inflammasome. OBJECTIVE: Because the intersections between autophagy and the inflammasome have been observed in patients with various diseases and microbial infections, we investigated the possible benefit of restoring the autophagy defect through rapamycin, a potent autophagy inducer, in the setting of CGD. METHODS: We studied 15 patients given a diagnosis of CGD and followed in our institution. All patients were free of any active infection at the time of the study. RESULTS: We show that patients with CGD present a consistent inflammatory phenotype defined by (1) increased nonclassical and intermediate monocytes, (2) a proinflammatory state of mononuclear phagocytes with increased IL-1beta and TNF alpha content, (3) a TH17 bias of CD4+ T cells, (4) and an increase in IL-17A secreting neutrophil numbers. We document the reversion of CGD inflammatory status by the mammalian target of rapamycin inhibitor rapamycin on the different immune cell subsets. We also provide evidence for the enhancement of rapamycin's inhibitory effect on IL-1beta secretion by the IL-1 receptor antagonist anakinra in phagocytes of patients with CGD. CONCLUSION: Altogether, these data open new therapeutic approaches for CGD-related inflammatory manifestations. PMID- 27702671 TI - Major differences between human atopic dermatitis and murine models, as determined by using global transcriptomic profiling. AB - BACKGROUND: Atopic dermatitis (AD) is caused by a complex interplay between immune and barrier abnormalities. Murine models of AD are essential for preclinical assessments of new treatments. Although many models have been used to simulate AD, their transcriptomic profiles are not fully understood, and a comparison of these models with the human AD transcriptomic fingerprint is lacking. OBJECTIVE: We sought to evaluate the transcriptomic profiles of 6 common murine models and determine how they relate to human AD skin. METHODS: Transcriptomic profiling was performed by using microarrays and quantitative RT PCR on biopsy specimens from NC/Nga, flaky tail, Flg-mutated, ovalbumin challenged, oxazolone-challenged, and IL-23-injected mice. Gene expression data of patients with AD, psoriasis, and contact dermatitis were obtained from previous patient cohorts. Criteria of a fold change of 2 or greater and a false discovery rate of 0.05 or less were used for gene arrays. RESULTS: IL-23 injected, NC/Nga, and oxazolone-challenged mice show the largest homology with our human meta-analysis-derived AD transcriptome (37%, 18%, 17%, respectively). Similar to human AD, robust TH1, TH2, and also TH17 activation are seen in IL-23 injected and NC/Nga mice, with similar but weaker inflammation in ovalbumin challenged mice. Oxazolone-challenged mice show a TH1-centered reaction, and flaky tail mice demonstrate a strong TH17 polarization. Flg-mutated mice display filaggrin downregulation without significant inflammation. CONCLUSION: No single murine model fully captures all aspects of the AD profile; instead, each model reflects different immune or barrier disease aspects. Overall, among the 6 murine models, IL-23-injected mice best simulate human AD; still, the translational focus of the investigation should determine which model is most applicable.

PMID- 27702674 TI - Cytotoxic effects of Aeromonas hydrophila culture supernatant on peripheral blood leukocytes of Nile tilapia (Oreochromis niloticus): Possible presence of a secreted cytotoxic lectin. AB - Number of exotoxins like haemolysin, leukocidin, aerolysin etc. were reported from Aeromonas hydrophila. In this study, we report the haemolytic and cytotoxic effect of A. hydrophila culture supernatant (CS) that is specifically inhibited by lactose and also by serum and mucus of Nile tilapia (Oreochromis niloticus). Hence, we assume the presence of a secreted lectin in the CS. CS is toxic to peripheral blood leukocytes (PBL) of O. niloticus as revealed by MTT assay and by flow cytometry. DNA laddering assay indicates that CS causes necrosis to PBL. As a result of necrosis, CS treated PBL showed increased production of reactive oxygen species as indicated by nitroblue tetrazolium and 2',7' dichlorofluorescin diacetate assays. CS treated PBL showed reduced mRNA expression of TNF-alpha and IFN-gamma genes. When CS was subjected to polyacrylamide gel electrophoresis, it showed a single band corresponding to the molecular weight of 45 kDa. However, upon concentrating the CS by ultrafiltration, many bands were visualized. Further studies at molecular level are required to unravel this macromolecular-leukocyte interaction which would ultimately benefit the aquaculture industry. PMID- 27702673 TI - Mechanism of TH2/TH17-predominant and neutrophilic TH2/TH17-low subtypes of asthma. AB - BACKGROUND: The mechanism of TH2/TH17-predominant and TH2/TH17-low asthma is unknown. OBJECTIVE: We sought to study the immune mechanism of TH2/TH17 predominant and TH2/TH17-low asthma. METHODS: In a previously reported cohort of 60 asthmatic patients, 16 patients were immunophenotyped with TH2/TH17 predominant asthma and 22 patients with TH2/TH17-low asthma. We examined bronchoalveolar lavage (BAL) fluid leukocytes, cytokines, mediators, and epithelial cell function for these asthma subgroups. RESULTS: Patients with TH2/TH17-predominant asthma had increased IL-1beta, IL-6, IL-23, C3a, and serum amyloid A levels in BAL fluid, and these correlated with IL-1beta and C3a levels. TH2/TH17 cells expressed higher levels of the IL-1 receptor and phospho-p38 mitogen-activated protein kinase. Anakinra, an IL-1 receptor antagonist protein, inhibited BAL TH2/TH17 cell counts. TH2/TH17-low asthma had 2 distinct subgroups: neutrophilic asthma (45%) and pauci-inflammatory asthma (55%). This contrasted with patients with TH2/TH17-predominant and TH2-predominant asthma, which included neutrophilic asthma in 6% and 0% of patients, respectively. BAL fluid neutrophils strongly correlated with BAL fluid myeloperoxidase, IL-8, IL-1alpha, IL-6, granulocyte colony-stimulating factor, and GM-CSF levels. Sixty percent of the patients with neutrophilic asthma had a pathogenic microorganism in BAL culture, which suggested a subclinical infection. CONCLUSION: We uncovered a critical role for the IL-1beta pathway in patients with TH2/TH17-predminant asthma. A subgroup of patients with TH2/TH17-low asthma had neutrophilic asthma and increased BAL fluid IL-1alpha, IL-6, IL-8, granulocyte colony-stimulating factor, and GM-CSF levels. IL-1alpha was directly involved in IL-8 production and likely contributed to neutrophilic asthma. Sixty percent of neutrophilic patients had a subclinical infection. PMID- 27702675 TI - Proteomic and metabolomic responses in D-shape larval mussels Mytilus galloprovincialis exposed to cadmium and arsenic. AB - Cadmium (Cd) and arsenic (As) are the main metal/metalloid contaminants in the coastal environments of the Bohai Sea, China. In this work, a combined proteomic and metabolomic approach was applied to investigate the biological effects of Cd and As (V) in the early life stage (D-shape larvae) of mussel Mytilus galloprovincialis. Results indicated that Cd was a potential immune toxicant to D shape larval mussel because of the numerous proteomic responses related to immune system. Additionally, Cd induced oxidative stress, cellular injury and disturbance in nucleic acid metabolism in D-shape larval mussels. However, only two identified proteins were significantly altered in As (V)-treated group, suggesting that D-shape larval mussel was less sensitive to As (V) than to Cd at protein level. These two proteins in response to As (V) suggested that As (V) influenced anti-oxidative system and cell proliferation in D-shape larval mussels. Metabolic responses indicated that Cd and As (V) induced disturbances in osmotic regulation and energy metabolism in D-shape larval mussels via different metabolic pathways. In addition, Cd reduced lipid metabolism as well. This work demonstrated that a combination of proteomics and metabolomics could provide an insightful view in the biological effects of pollutants in mussel M. galloprovincialis at an early life stage. PMID- 27702676 TI - Oreochromis mossambicus diet supplementation with Psidium guajava leaf extracts enhance growth, immune, antioxidant response and resistance to Aeromonas hydrophila. AB - In this research, we focused on the efficacy of aqueous and ethanol leaf extracts of Psidium guajava L. (guava) based experimental diets on the growth, immune, antioxidant and disease resistance of tilapia, Oreochromis mossambicus following challenge with Aeromonas hydrophila. The experimental diets were prepared by mixing powdered (1, 5 and 10 mg/g) aqueous and ethanol extract of guava leaf with commercial diet. The growth (FW, FCR and SGR), non-specific cellular immune (myeloperoxidase activity, reactive oxygen activity and reactive nitrogen activity) humoral immune (complement activity, antiprotease, alkaline phosphatase activity and lysozyme activity) and antioxidant enzyme responses (SOD, GPX, and CAT) were examined after 30 days of post-feeding. A significant enhancement in the biochemical and immunological parameters of fish were observed fed with experimental diets compared to control. The dietary supplementation of P. guajava leaf extract powder for 30 days significantly reduced the mortality and increased the disease resistance of O. mossambicus following challenge with A. hydrophila at 50 MUl (1 * 107 cells ml-1) compared to control after post-infection. The results suggest that the guava leaf extract could be used as a promising feed additive in aquaculture. PMID- 27702678 TI - Parental care improves immunity in the seahorse (Hippocampus erectus). AB - In the present study, the sexual dimorphism in immune response in the seahorse Hippocampus erectus in which males compete for mates and invest heavily in parental care was assessed. Variability in immunocompetence in virginal seahorses with differing levels of sexual maturity (i.e., immaturity, early maturity and maturity) and with different mating statuses (i.e., virginal, experienced mating failure and experienced mating success) were analyzed by evaluating immune parameters in the plasma. Additionally, ultrastructural characteristics of the inner epithelium of the brood pouch were compared between males that had experienced mating failure and those that had succeeded. Generally, immunity in sexually mature virgin males was greater than in females, and mating competition significantly reduced males' immunity. However, parental care gave males stronger immune and metabolic abilities and resulted in their immunity significantly rebounding after a successful mating. The present study quantitatively clarifies, for the first time, how parental care and mating competition jointly affect immunity. Moreover, previous findings that females display more efficient immune defenses than males in conventional species (i.e., males are as competitor and females as care giver) and that males' immunity is higher than females' in the pipefish (i.e., females are as competitor and males as care giver) in combination with the present results indicate that parental care is a key factor for sexual dimorphism in immunity. The care-giving sex has strong immunity regardless of the sex in charge of mating competition or not. PMID- 27702677 TI - Immune reactivity in early life stages of sea-cage cultured Pacific bluefin tuna naturally infected with blood flukes from genus Cardicola (Trematoda: Aporocotylidae). AB - Pacific bluefin tuna (PBT), Thunnus orientalis, due to its high average price on the market is an economically valuable fish species. Infections by blood flukes from the genus Cardicola (Trematoda: Aporocotylidae) represent a growing concern for the cage culture of bluefin tuna in Japan, Australia and Southern Europe. The accumulation of numerous Cardicola eggs in the fish gills causes severe pathology that has been linked to mortality in PBT juveniles up to one year old. The only effective treatment used to mitigate the infection is the oral administration of the antihelminthic drug praziquantel (PZQ) to the affected fish. However, with the need to minimise therapeutic drug use in aquaculture it is hoped that immunoprophylaxis can provide a future alternative to protect the PBT juveniles against Cardicola infection. Currently, little is known of the host immune response to these parasites and of their infection dynamics. In this study, using real-time qPCR we aimed to quantitatively detect C. orientalis and C. opisthorchis DNA within the gills and heart of cultured PBT juveniles and to investigate the host immune response at the transcriptional level in the gills. The research focused mainly during early stages of infection soon after young PBT were transferred to culture cages (from 14 to 77 days post-transfer). An increase (up to 11-fold) of immune-related genes, namely IgM, MHC-I, TCR-beta and IL-1beta was observed in the PBT gills infected with Cardicola spp. (28-77 days post transfer). Furthermore, IgM (19-fold increase) and MHC-I (11.5-fold increase) transcription was strongly up-regulated in gill samples of PBT infected with C. orientalis relative to uninfected fish but not in fish infected with C. opisthorchis. Cardicola-specific DNA was first detected in the host 14 days post transfer (DPT) to sea-cages which was 55 days earlier than the first detection of parasite eggs and adults by microscopy. Oral administration of PZQ did not have an immediate effect on parasite DNA presence in the host and the DNA presence started to reduce after 24 days only in the host heart. The results provide evidence of an immune response in early age sea-cage cultured juveniles of PBT naturally infected with C. orientalis and C. opisthorchis. This response, whilst not protective against primary infection, provides evidence that immunisation at an early age may have potential as a health strategy. PMID- 27702679 TI - Characterization of IgM in Norwegian cleaner fish (lumpfish and wrasses). AB - The use of cleaner fish in Norwegian aquaculture has to a large extent been based on wild catches, but breeding of lumpfish and ballan wrasse is currently increasing. Due to disease problems and required vaccine development, tools to study immune responses and a better understanding of the immune system in these species is demanded. The present study comprises lumpfish (Cyclopterus lumpus) and five species of wrasses: Ballan wrasse (Labrus bergylta), rock cook (Centrolabrus exoletus), cuckoo wrasse (Labrus mixtus), corkwing wrasse (Symphodus melops), and goldsinny wrasse (Ctenolabrus rupestris). We present a comparison of the IgM sequences, phylogenetic relationship to other teleosts and characteristic features of IgM in the species studied. The lumpfish IgM heavy chain sequence was assembled from high throughput cDNA sequencing whereas the wrasse sequences were determined by molecular cloning. The secreted form of the IgM heavy chain from all species consisted of four constant Ig domains. IgM was purified from lumpfish and ballan wrasse sera by gel filtration followed by anion exchange chromatography, and polyclonal sera were produced against these proteins. Antisera against ballan wrasse IgM showed cross-reactivity to all analyzed species of wrasses, some cross-reactivity to lumpfish, very low reaction to salmon, and no reaction to cod. Anti- IgM sera against lumpfish cross-reacted to the light chain of all species studied. Wrasses and lumpfish IgM showed high binding affinities for protein A. IgM concentration in adult ballan wrasse (700 800 g) was measured by single radial immunodiffusion assay and found to be 13.4 mg/ml which is about 36% of the total protein concentration. The IgM concentration in lumpfish (600-3600 g) was estimated to 1-2.6 mg/ml, which corresponds to approximately 3% of the total protein concentration.

PMID- 27702681 TI - Targeting the complex interactions between microbiota, host epithelial and immune cells in inflammatory bowel disease. AB - Inflammatory bowel disease (IBD) is a chronic inflammatory intestinal disorder that includes two distinct disease categories: ulcerative colitis and Crohn's disease. Epidemiological, genetic, and experimental studies have revealed many important aspects of IBD. Genetic susceptibility, inappropriate immune responses, environmental changes, and intestinal microbiota are all associated with the development of IBD. However, the exact mechanisms of the disease and the interactions among these pathogenic factors are largely unknown. Here we introduce recent findings from experimental colitis models that investigated the interactions between host genetic susceptibility and gut microbiota. In addition, we discuss new strategies for the treatment of IBD, focusing on the complex interactions between microbiota and host epithelial and immune cells. PMID- 27702682 TI - Perinatal programming of depressive-like behavior by inflammation in adult offspring mice whose mothers were fed polluted eels: Gender selective effects. AB - Several lines of evidence indicate that early-life inflammation may predispose to mental illness, including depression, in later-life. We investigated the impact of perinatal exposure to polluted eels on neonatal, postnatal, and adult brain inflammation, and on the resignation behavior of male and female adult offspring mice. The effects of maternal standard diet (laboratory food) were compared to the same diet enriched with low, intermediate, or highly polluted eels. Brain inflammatory markers including cytokines were assessed in offspring mice on the day of birth (i.e., on the postnatal day-PND 1), upon weaning (PND 21) and at adulthood (PND 100). Plasma myeloperoxidase and corticosterone levels were evaluated at PND 100. Immobility behavior of offspring was assessed in adulthood (i.e., at PNDs 95-100), using the tail suspension and forced swimming tests. Chronic brain inflammation was found in male and female offspring mice compared to controls, as assessed at PNDs 1, 21, and 100. The level of myeloperoxidase was found to be significantly higher in both adult males and females vs. control offspring. However, high corticosterone levels were only found in male offspring mice that were perinatally exposed to eels, suggesting a gender-selective dysregulation of the adult hypothalamic-pituitaryadrenal (HPA) axis. Gender specific differences were also detected in adulthood in regard to offspring resignation behavior. Thus, compared to controls, males, but not females, whose mothers were fed eels during pregnancy and lactation exhibited a depressive-like behavior in adult age in both behavioral models of depression. Depressive symptoms were more pronounced in male mice perinatally exposed to either intermediate or highly polluted eels than those exposed to only lowly polluted eels. Our results indicate that early-life inflammatory insult is a plausible causative factor that induces the depressive phenotype exhibited by male adult offspring mice, most likely through a gender-specific HPA axis enhanced activation. PMID- 27702683 TI - Trends of the microcephaly and Zika virus outbreak in Brazil, January-July 2016. AB - In the last two months, there have been indications that the Zika virus epidemic is on the decline in Brazil. We reviewed the surveillance data published by the Brazilian Ministry of Health to assess trends of microcephaly and neurological abnormalities suggestive of congenital infection, as well as Zika virus disease in Brazil as a whole and its various regions. From November 2015 to July 2016, 8301 cases of microcephaly were reported in Brazil, mainly in the Northeast region. The number of newly reported cases is declining throughout the country, except in the Southeast region. The numbers of cases that remain under investigation still represent 37.7% of all reported cases in early July. Meanwhile, from January to June, 2016, 165,241 cases of Zika virus disease were reported in Brazil. The state of Rio de Janeiro (Southeast) experienced the third highest incidence, lagging behind only the states of Bahia (Northeast) and Mato Grosso (Midwest). In early June, the number of new Zika virus cases showed a marked decline in all of the regions, except the North. Although the Zika epidemic seems to be diminishing, continued monitoring and surveillance of reported microcephaly and neurological abnormality cases is essential, and investigation efforts need to be vastly improved, as some states still reported high incidences of Zika disease in the first half of 2016. PMID- 27702684 TI - Lipopeptide-based micellar and liposomal carriers: Influence of surface charge and particle size on cellular uptake into blood brain barrier cells. AB - Lipopeptide-based micelles and liposomes were found to differ in cell recognition and uptake mode into blood brain barrier (BBB) endothelial cells. Here we analyse the role of size and surface charge of micelles and liposomes composed of different lipopeptide sequences with respect to uptake into human brain capillary (HBMEC) and aortic (HAoEC) endothelial cells. Comparable to the dipalmitoylated apolipoprotein E-derived P2A2, lipopeptides of cationic poly-arginine (P2Rn), poly-lysine (P2Kn) and an anionic glutamic-acid sequence (P2En) self assemble into micelles (12-14nm in diameter) with high surface charge density, and bind to small (SUVs, about 24nm in diameter) and large (LUV, about 100nm in diameter) liposomes at variable lipid to peptide ratios. The interaction pattern of the resulting particles with endothelial cells is highly variable as revealed by confocal laser scanning microscopic (CLSM) and fluorescence assisted cell sorting (FACS) studies. Micelles and SUVs with high P2A2 density are efficiently and selectively internalized into HBMEC. P2Kn micelles strongly accumulate in both the cytosol and at the cell membrane, while the interaction of liposomes tagged with a low amount of P2A2 and P2Kn with the cells was reduced. Anionic micelles seem to dissociate in the presence of cells and P2En molecules incorporate into the cellular membrane whereas the negatively charged liposomes hardly interact with cells. Surprisingly, all poly-R-based particles show high selectivity for HBMEC compared to HAoEC, independent of particle size and peptide surface density. The P2Rn-mediated internalization is highly efficient and partially clathrin-dependent. The oligo-R lipopeptide is considered to be most promising to selectively transport different drug carriers into the blood brain barrier. PMID- 27702685 TI - Conjugates of HA2 with octaarginine-grafted HPMA copolymer offer effective siRNA delivery and gene silencing in cancer cells. AB - The key for successful gene silencing is to design a safe and efficient siRNA delivery system for the transfer of therapeutic nucleic acids into the target cells. Here, we describe the design of hydrophilic N-(2 hydroxypropyl)methacrylamide (HPMA) copolymer displaying multiple copies of octaarginine (R8) and its use in promoting the effective delivery of small interfering RNA (siRNA) molecules intracellularly. Fluorescein-5-isothiocyanate (FITC)-labeled HPMA copolymer-bound R8 (P-R8-FITC) was synthesized with increasing R8 molar ratios (4-9.5mol-%) to define the optimal R8 content that allowed the polymer to serve both as a siRNA-binding domain and as an intracellular transduction moiety mediating improved cellular delivery. A subunit of the influenza virus hemagglutinin (HA2), known for its ability to disrupt endosomal membranes, was further conjugated to P-R8-FITC copolymer to promote endosomal escape. Of the different P-(R8)-FITC conjugates considered, only that polymer containing the highest mol-% of R8 (P-(R8)9.5-FITC) was able to encapsulate siRNA molecules into nano-sized polyion complexes (PICs) presenting positive surface charge, low in vitro cytotoxicity, and high serum stability. P (R8)9.5-FITC/cy5-siRNA complexes can efficiently deliver siRNA molecules into cells, while naked siRNA or siRNA encapsulated within polymers with lower R8mol-% were unable to transfect the same cells. Conjugation of HA2 fusogenic peptide to P-(R8)-FITC significantly decreased the oncogenic RAC1 mRNA levels in cancer cells. This indicates that P-(R8)-(HA2)-FITC can deliver siRNA into target cells, and that the siRNA can reach the perinuclear region where it interacts with the RNA-induced silencing complex. PMID- 27702686 TI - Inhibition of carbonic anhydrase IX in glioblastoma multiforme. AB - Carbonic anhydrase IX (CAIX) is a transmembrane enzyme upregulated in several types of tumors including glioblastoma multiforme (GBM). GBM is among the most aggressive tumors among gliomas. Temozolomide (TMZ) therapy combined with surgical or radiation approaches is the standard treatment but not effective in long term. In this study we tested the treatment with acetazolamide (ATZ), an inhibitor of CAIX, alone or combined with TMZ. The experiments were performed in 2D and 3D cultures (spheroids) using glioblastoma U251N and human brain tumor stem cells (BTSCs). Several proteins implicated in tumor cell death were also investigated. The key results from these studies suggest the following: (1) Cell death of human glioblastoma spheroids and BTSC is significantly increased with combined treatment after 7 days, and (2) the effectiveness of ATZ is significantly enhanced against BTSC and U251N when incorporated into nano carriers. Collectively, these results point toward the usefulness of nano delivery of CAIX inhibitors and their combination with chemotherapeutics for glioblastoma treatment. PMID- 27702687 TI - Innovative drug vehicle for local treatment of inflammatory skin diseases: Ex vivo and in vivo screening of five topical formulations containing poly(lactic acid) (PLA) nanoparticles. AB - One of the main goals in the galenic development of innovative topical treatment options for inflammatory skin diseases such as psoriasis and atopic dermatitis is to selectively deliver the drug at the inflammation site. Recent studies have highlighted the beneficial use of polymeric nanoparticles for anti-inflammatory therapy and topical anti-inflammatory drug delivery due to their ability to form a drug reservoir retaining the drug locally at the site of action. Our approach consisted in designing innovative topical semi-solid formulations of poly(lactic acid) (PLA) nanoparticles as anti-inflammatory drug vehicles for local treatment of inflammatory skin diseases. In the course of this work, five topical formulations containing fluorescent PLA nanoparticles were initially developed, and then screened depending on their physico-chemical properties, toxicity and delivery efficacy. The penetration and permeation of a fluorophore vectorized by PLA nanoparticles into healthy and inflammatory skin were assessed using an alternative device to classical Franz cells: VitroPharma. All these investigations led to the selection of two satisfactory formulations out of five initial candidates.

AB - This work focuses on the performance of ten commercial Saccharomyces yeast strains in the batch alcoholic fermentation of sugars contained in selected industrial wastewaters from the soft drink industry. Fermentation has been applied successfully to treat these effluents prior to their disposal. Although many strains were investigated, similar behaviour was observed between all of the Saccharomyces strains tested. When media were inoculated with 2gL-1 of yeast, all strains were able to completely consume the available sugars in less than 14h. Thus, any of the strains studied in this work could be used in non-conventional wastewater treatment processes based on alcoholic fermentation. However, ethanol production varied between strains, and these differences could be significant from a production point of view. Saccharomyces bayanus produced the most ethanol, with a mean yield of 0.44gethanolgsugarconsumed-1 and an ethanol specific production rate of 5.96gethanol (Lh)-1. As the assayed soft drinks wastewaters contain about 105gsugar/L of fermentable sugars, the concentration of ethanol achieved after the fermentations process was 46.2gethanol/L. A rigorous kinetic modelling methodology was used to model the Saccharomyces bayanus fermentation process. The kinetic model included coupled mass balances and a minimal number of parameters. A simple unstructured model based on the Andrews equation (substrate inhibition) was developed. This model satisfactorily described biomass growth, sugar consumption and bioethanol production. In addition to providing insights into the fermentative performance of potentially relevant strains, this work can facilitate the design of large-scale ethanol production processes that use wastewaters from the sugar-sweetened beverage industry as feedstock. PMID- 27702690 TI - Andrographis paniculata: Dissolution investigation and pharmacokinetic studies of four major active diterpenoids after multiple oral dose administration in healthy Thai volunteers. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Andrographis paniculata is included in 'The National List of Essential Herbal Drugs A.D. 1999' of Thailand as an herbal drug for the treatment of common cold symptoms and non-infectious diarrhea. The therapeutic activities of A. paniculata are attributed to four major active diterpenoids: andrographolide (1), 14-deoxy-11, 12-didehydroandrographolide (2), neoandrographolide (3), and 14-deoxyandrographolide (4). However, the pharmacokinetic studies in humans of this plant were performed after a single oral dose administration and reported the parameters related to be of only 1. AIM OF THE STUDY: This study aims to determine the pharmacokinetic parameters of four major active diterpenoids after multiple oral dose administration of A. paniculata capsules in healthy volunteers. The dissolution testing of these four diterpenoids was also performed. MATERIALS AND METHOD: The dissolution testing of four major active diterpenoids was conducted in pH 1.2, pH 4.5, and pH 6.8 for 10 100min. The pharmacokinetic study of these active diterpenoids was designed as an open-label, multiple oral dose administration of A. paniculata capsules in 20 healthy Thai volunteers at 1:1 ratio of female and male. Each volunteer was given four A. paniculata capsules each time which contained 1, 2, 3, and 4 in the quantities of 32.64, 5.40, 3.60, and 3.84mg, respectively, three times a day for three consecutive days. On the fourth day, after the first dose of the day was administered, blood samples were collected at the predefined time points. The validated LC-MS/MS method was used to simultaneously determine the concentrations of these diterpenoids in the human plasma samples. The pharmacokinetic parameters of each active diterpenoid were determined. RESULTS: All four major active diterpenoids have been completely dissolved in the simulated pH of gastrointestinal tract within 60min of dissolution. The dissolution profiles were found to be highest in pH 6.8 and lowest in pH 1.2, especially for 3. In the pharmacokinetic study, although 1 was administered at the highest dose among these four diterpenoids, 2 exhibited the highest maximum concentrations (Cmax) of 44.89ng/mL and area under the plasma concentration-time curve (AUC) of 128.17h*ng/mL. Compound 1 had the second highest Cmax and AUC as 32.41ng/mL and 55.23h*ng/mL, respectively. The relative systemic exposure, represented by the dose normalized AUC [(h*ng/mL)/(mg/kg)], of 2 was approximately 14 times higher than that of 1, while those of 3 and 4 were approximately 1.5 and 1.6 times higher, respectively. Cmax, AUC, apparent volume of distribution, and apparent clearance of 2 were found to be significant difference between female and male. However, when these parameters were calculated as dose normalized basis, no statistically significant difference was found. CONCLUSION: The four major active diterpenoids in the A. paniculata capsules were soluble in all studied dissolution media. The pharmacokinetic parameters of these active diterpenoids in the present study could be applied for dose optimization of A. paniculata product in order to obtain good therapeutic efficacy and reduce the possible side effects that may occur from different active diterpenoids in this medicinal plant. PMID- 27702689 TI - Screening of soluble epoxide hydrolase inhibitory ingredients from traditional Chinese medicines for anti-inflammatory use. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Inhibition of soluble epoxide hydrolase (sEH) has been extensively reported to be anti-inflammatory in multiple animal models. Some anti-inflammatory traditional Chinese medicines (TCMs) and a few natural compounds were also found to be inhibitory to sEH in vitro. AIM OF THE STUDY: To determine whether the active intergradient (AI) against sEH of anti-inflammatory TCMs in vitro is anti-inflammatory in vivo and the sEH inhibitory action of the AI contributes to its anti-inflammatory effect in vivo. MATERIALS AND METHODS: In vitro inhibition assay of the sEH was conducted for the methanol and ethanol extracts of 27 anti-inflammatory TCMs. Two potent extracts were subject to further separation guided by bioassay to afford promising AI against sEH in vitro [Fr.5 of the crude ethanol extract of Rhizoma coptidis (FFCERC)]. Finally, the in vivo anti-inflammatory effect and sEH inhibitory potency of FFCERC was evaluated in a lipopolysacchride (LPS)-challenged murine model of acute systemic inflammation. The inflammatory status was characterized by the inflammatory cytokines TNF-alpha and interleukin-6 (IL-6) and sEH inhibitory function was evaluated by the plasma levels of epoxyeicosantrienoic acids (EETs) and dihydroxyeicosatrienoic acids (DHETs), which are the sEH mediated substrates and products, respectively. RESULTS: At the concentration of 25ug/mL, the crude ethanol extracts of 6 TCMs including Herba Asari, Radix Polygalae, Fructus Amomi, Radix Astragali, Radix Scutellariae, and Rhizoma Coptidis were potent against sEH. The crude extracts of Herba Asari and Rhizoma Coptidis were selected for further separation to afford FFCERC as the most promising AI for in vivo evaluation. Oral administration of FFCERC attenuated the significant increase in TNF-alpha and IL-6 caused by LPS challenge in a dose-dependent manner. In parallel, oral administration of FFCERC shifted the changes in plasma levels of EETs and DHETs caused by LPS-challenge like a synthetic sEH inhibitor. CONCLUSIONS: A sEH inhibitory AI from Rhizoma Coptidis is anti-inflammatory and the inhibition of sEH contributes to this biological effect, indicating that sEH may be at least one of multiple therapeutic targets for relevant TCMs. PMID- 27702692 TI - The High Light Response and Redox Control of Thylakoid FtsH Protease in Chlamydomonas reinhardtii. AB - In Chlamydomonas reinhardtii, the major protease involved in the maintenance of photosynthetic machinery in thylakoid membranes, the FtsH protease, mostly forms large hetero-oligomers (~1 MDa) comprising FtsH1 and FtsH2 subunits, whatever the light intensity for growth. Upon high light exposure, the FtsH subunits display a shorter half-life, which is counterbalanced by an increase in FTSH1/2 mRNA levels, resulting in the modest upregulation of FtsH1/2 proteins. Furthermore, we found that high light increases the protease activity through a hitherto unnoticed redox-controlled reduction of intermolecular disulfide bridges. We isolated a Chlamydomonas FTSH1 promoter-deficient mutant, ftsh1-3, resulting from the insertion of a TOC1 transposon, in which the high light-induced upregulation of FTSH1 gene expression is largely lost. In ftsh1-3, the abundance of FtsH1 and FtsH2 proteins are loosely coupled (decreased by 70% and 30%, respectively) with no formation of large and stable homo-oligomers. Using strains exhibiting different accumulation levels of the FtsH1 subunit after complementation of ftsh1 3, we demonstrate that high light tolerance is tightly correlated with the abundance of the FtsH protease. Thus, the response of Chlamydomonas to light stress involves higher levels of FtsH1/2 subunits associated into large complexes with increased proteolytic activity. PMID- 27702691 TI - Targeting acid sphingomyelinase with anti-angiogenic chemotherapy. AB - Despite great promise, combining anti-angiogenic and conventional anti-cancer drugs has produced limited therapeutic benefit in clinical trials, presumably because mechanisms of anti-angiogenic tissue response remain only partially understood. Here we define a new paradigm, in which anti-angiogenic drugs can be used to chemosensitize tumors by targeting the endothelial acid sphingomyelinase (ASMase) signal transduction pathway. We demonstrate that paclitaxel and etoposide, but not cisplatin, confer ASMase-mediated endothelial injury within minutes. This rapid reaction is required for human HCT-116 colon cancer xenograft complete response and growth delay. Whereas VEGF inhibits ASMase, anti-VEGFR2 antibodies de-repress ASMase, enhancing endothelial apoptosis and drug-induced tumor response in asmase+/+, but not in asmase-/-, hosts. Such chemosensitization occurs only if the anti-angiogenic drug is delivered 1-2h before chemotherapy, but at no other time prior to or post chemotherapy. Our studies suggest that precisely-timed administration of anti-angiogenic drugs in combination with ASMase-targeting anti-cancer drugs is likely to optimize anti-tumor effects of systemic chemotherapy. This strategy warrants evaluation in future clinical trials. PMID- 27702693 TI - Photorespiration Is Crucial for Dynamic Response of Photosynthetic Metabolism and Stomatal Movement to Altered CO2 Availability. AB - The photorespiratory pathway or photorespiration is an essential process in oxygenic photosynthetic organisms, which can reduce the efficiency of photosynthetic carbon assimilation and is hence frequently considered as a wasteful process. By comparing the response of the wild-type plants and mutants impaired in photorespiration to a shift in ambient CO2 concentrations, we demonstrate that photorespiration also plays a beneficial role during short-term acclimation to reduced CO2 availability. The wild-type plants responded with few differentially expressed genes, mostly involved in drought stress, which is likely a consequence of enhanced opening of stomata and concomitant water loss upon a shift toward low CO2. In contrast, mutants with impaired activity of photorespiratory enzymes were highly stressed and not able to adjust stomatal conductance to reduced external CO2 availability. The transcriptional response of mutant plants was congruent, indicating a general reprogramming to deal with the consequences of reduced CO2 availability, signaled by enhanced oxygenation of ribulose-1,5-bisphosphate and amplified by the artificially impaired photorespiratory metabolism. Central in this reprogramming was the pronounced reallocation of resources from growth processes to stress responses. Taken together, our results indicate that unrestricted photorespiratory metabolism is a prerequisite for rapid physiological acclimation to a reduction in CO2 availability. PMID- 27702694 TI - Thoracic Endovascular Aortic Repair for Embolizing Total Occlusion of the Descending Aorta due to Aortic Sarcoma. AB - Primary malignant tumors of the aorta are extremely rare, and the diagnosis is difficult from the clinical onset. Accordingly to the principles of cancer surgery, "en bloc" resection of the tumor-involved aorta and graft interposition is the gold standard, but it is still technically challenging and comorbidities may rule out some patients from an operative treatment. Thoracic endovascular aortic repair has been reported anecdotally, but it is an ease and rapid alternative in urgent circumstances and proved to be effective to relieve symptoms caused by these lesions. Unfortunately, no matter what is the type of histology or immunohistochemistry, or the type of treatment, the prognosis of aortic malignancies is very poor. Nevertheless, an operative treatment strategy which includes surgical resection and chemotherapy or radiation had long survival than patients treated with a single modality. We report a case of acute mesenteric syndrome caused by an occlusive and embolizing thrombus of the descending thoracic aorta caused by primary aortic sarcoma treated with thoracic endovascular aortic repair. PMID- 27702695 TI - Multispectral UV imaging for surface analysis of MUPS tablets with special focus on the pellet distribution. AB - In the present study the applicability of multispectral UV imaging in combination with multivariate image analysis for surface evaluation of MUPS tablets was investigated with respect to the differentiation of the API pellets from the excipients matrix, estimation of the drug content as well as pellet distribution, and influence of the coating material and tablet thickness on the predictive model. Different formulations consisting of coated drug pellets with two coating polymers (Aquacoat(r) ECD and Eudragit(r) NE 30 D) at three coating levels each were compressed to MUPS tablets with various amounts of coated pellets and different tablet thicknesses. The coated drug pellets were clearly distinguishable from the excipients matrix using a partial least squares approach regardless of the coating layer thickness and coating material used. Furthermore, the number of the detected drug pellets on the tablet surface allowed an estimation of the true drug content in the respective MUPS tablet. In addition, the pellet distribution in the MUPS formulations could be estimated by UV image analysis of the tablet surface. In conclusion, this study revealed that UV imaging in combination with multivariate image analysis is a promising approach for the automatic quality control of MUPS tablets during the manufacturing process. PMID- 27702696 TI - Reevaluation of the diametral compression test for tablets using the flattened disc geometry. AB - Mechanical strength is an important critical quality attribute for tablets. It is classically measured, in the pharmaceutical field, using the diametral compression test. Nevertheless, due to small contact area between the tablet and the platens, some authors suggested that during the test, the failure could occur in tension away from the center which would invalidate the test and the calculation of the tensile strength. In this study, the flattened disc geometry was used as an alternative to avoid contact problems. The diametral compression on both flattened and standard geometries was first studied using finite element method (FEM) simulation. It was found that, for the flattened geometry, both maximum tensile strain and stress were located at the center of the tablet, which was not the case for the standard geometry. Experimental observations using digital image correlation (DIC) confirmed the numerical results. The experimental tensile strength obtained using both geometries were compared and it was found that the standard geometry always gave lower tensile strength than the flattened geometry. Finally, high-speed video capture of the test made it possible to detect that for the standard geometry the crack initiation was always away from the center of the tablet. PMID- 27702697 TI - Application of RPMI 2650 as a cell model to evaluate solid formulations for intranasal delivery of drugs. AB - During the development of intranasal drug delivery systems for local/systemic effect or brain targeting, it is necessary to assess its cytotoxicity and drug transport through nasal epithelium. In order to avoid animal experiments or the use of excised tissues, in vitro cell models, such as RPMI 2650 cells, are being preferred during recent years. Nevertheless, the deposition of solid formulations into nasal cell layers with further transepithelial transport rate of drugs has been poorly studied or reported. Thus, the purpose of this work is to further investigate RPMI 2650 cell line as an effective alternative to animal tissues for solid drug-loaded formulations cytotoxicity and drug permeation studies in order to become an option as a tool for drug discovery. Furthermore, we wanted to determine the extent to which the administration of drugs in particulate forms would differ in relation to the permeability of the same compounds applied as solutions. RPMI 2650 cells were cultured in submersed or at air-liquid interface conditions and characterized regarding transepithelial electrical resistance (TEER) and production of mucus. Pure ketoprofen (used as model compound) and five formulations loaded with same drug, namely solid lipid particles (Gelucire 43/01TM), structured lipid particles (Gelucire 43/01TM:Glyceryl monooleate) and aerogel microparticles (Alginate, Alginate:Pectin, Alginate:Carrageenan), were evaluated with RPMI 2650 model in terms of cytotoxicity and permeability of drug (applied as solution, dispersion or powder+buffer). RPMI 2650 cells were capable to grow in monolayer and multilayer, showing the same permeability as excised human nasal mucosa for sodium fluorescein (paracellular marker), with analogous TEER values and production of mucus, as referred by other authors. None of the powders showed cytotoxicity when applied to RPMI 2650 cells. Regarding permeation of drug through cell layers, not only the form of application of powders but also their physical and chemical properties affected the final permeation of active pharmaceutical ingredient. Aerogel microparticles administered directly to the cell layer (powder+buffer) exhibited the highest permeation-enhancing effect compared to the pure drug, which can be attributed to the mucoadhesive properties of the materials composing the carriers, proving to be an attractive formulation for nasal drug delivery. According to these results, RPMI 2650 showed to be a promising alternative to ex vivo or in vivo nasal models for cytotoxicity and evaluation of drug permeability of nasal drug-loaded formulations. PMID- 27702699 TI - Targeting chaperones, heat shock factor-1, and unfolded protein response: Promising therapeutic approaches for neurodegenerative disorders. AB - Protein misfolding, which is known to cause several serious diseases, is an emerging field that addresses multiple therapeutic areas. Misfolding of a disease specific protein in the central nervous system ultimately results in the formation of toxic aggregates that may accumulate in the brain, leading to neuronal cell death and dysfunction, and associated clinical manifestations. A large number of neurodegenerative diseases in humans, including Alzheimer's, Parkinson's, Huntington's, and prion diseases, are primarily caused by protein misfolding and aggregation. Notably, the cellular system is equipped with a protein quality control system encompassing chaperones, ubiquitin proteasome system, and autophagy, as a defense mechanism that monitors protein folding and eliminates inappropriately folded proteins. As the intrinsic molecular mechanisms of protein misfolding become more clearly understood, the novel therapeutic approaches in this arena are gaining considerable interest. The present review will describe the chaperones network and different approaches as the therapeutic targets for neurodegenerative diseases. Current and emerging therapeutic approaches to combat neurodegenerative diseases, addressing the roles of molecular, chemical, and pharmacological chaperones, as well as heat shock factor 1 and the unfolded protein response, are also discussed in detail. PMID- 27702700 TI - Sarcopenic obesity or obese sarcopenia: A cross talk between age-associated adipose tissue and skeletal muscle inflammation as a main mechanism of the pathogenesis. AB - Sarcopenia, an age-associated decline in skeletal muscle mass coupled with functional deterioration, may be exacerbated by obesity leading to higher disability, frailty, morbidity and mortality rates. In the combination of sarcopenia and obesity, the state called sarcopenic obesity (SOB), some key age- and obesity-mediated factors and pathways may aggravate sarcopenia. This review will analyze the mechanisms underlying the pathogenesis of SOB. In obese adipose tissue (AT), adipocytes undergo hypertrophy, hyperplasia and activation resulted in accumulation of pro-inflammatory macrophages and other immune cells as well as dysregulated production of various adipokines that together with senescent cells and the immune cell-released cytokines and chemokines create a local pro inflammatory status. In addition, obese AT is characterized by excessive production and disturbed capacity to store lipids, which accumulate ectopically in skeletal muscle. These intramuscular lipids and their derivatives induce mitochondrial dysfunction characterized by impaired beta-oxidation capacity and increased reactive oxygen species formation providing lipotoxic environment and insulin resistance as well as enhanced secretion of some pro-inflammatory myokines capable of inducing muscle dysfunction by auto/paracrine manner. In turn, by endocrine manner, these myokines may exacerbate AT inflammation and also support chronic low grade systemic inflammation (inflammaging), overall establishing a detrimental vicious circle maintaining AT and skeletal muscle inflammation, thus triggering and supporting SOB development. Under these circumstances, we believe that AT inflammation dominates over skeletal muscle inflammation. Thus, in essence, it redirects the vector of processes from "sarcopenia->obesity" to "obesity->sarcopenia". We therefore propose that this condition be defined as "obese sarcopenia", to reflect the direction of the pathological pathway. PMID- 27702701 TI - The Effect of Vertical Versus Horizontal Vaginal Cuff Closure on Vaginal Length After Laparoscopic Hysterectomy. AB - : STUDY OBJECTIVE: To determine whether vertical versus horizontal closure of the vaginal cuff during laparoscopic hysterectomy has an effect on postoperative vaginal length and pelvic organ prolapse. DESIGN: A prospective randomized controlled trial. Subjects were randomly assigned to vertical or horizontal vaginal cuff closure at the time of total laparoscopic hysterectomy. Pelvic organ prolapse quantization (POP-Q) tests were performed before surgery, 2 to 4 weeks after surgery, and 3 to 4 months after surgery (Canadian Task Force classification I). SETTING: An academic university-affiliated community hospital. PATIENTS: Patients undergoing laparoscopic or robotic-assisted laparoscopic total hysterectomy for benign or malignant disease, excluding those undergoing radical hysterectomy or concomitant pelvic floor procedure. INTERVENTIONS: Subjects were randomized into the vertical or horizontal vaginal cuff closure group. Total hysterectomy was completed with traditional laparoscopic techniques or with robotic assistance. A colpotomy ring was used in each subject. Vaginal cuff closure was performed with barbed suture in a running fashion according to the group assignment. MEASUREMENTS AND MAIN RESULTS: A total of 43 subjects were enrolled and randomized. One patient was excluded because the vaginal cuff was closed vaginally, 1 cancelled surgery, and 1 was completed without a uterine manipulator. The mean change in vaginal length was -0.89 cm (standard deviation [SD] = 1.03) in the horizontal group and -0.86 cm (SD = 1.19) in the vertical group (p = .57). POP-Q evaluation revealed no differences between groups and an overall trend toward improved POP-Q measurements. The average duration of vaginal cuff closure did not differ (p = .45), and there were no intraoperative complications related to vaginal cuff closure. CONCLUSION: Horizontal and vertical laparoscopic closure of the vaginal cuff after laparoscopic hysterectomy results in similar changes in vaginal length and other POP-Q scores. PMID- 27702698 TI - Life and death in the trash heap: The ubiquitin proteasome pathway and UCHL1 in brain aging, neurodegenerative disease and cerebral Ischemia. AB - The ubiquitin proteasome pathway (UPP) is essential for removing abnormal proteins and preventing accumulation of potentially toxic proteins within the neuron. UPP dysfunction occurs with normal aging and is associated with abnormal accumulation of protein aggregates within neurons in neurodegenerative diseases. Ischemia disrupts UPP function and thus may contribute to UPP dysfunction seen in the aging brain and in neurodegenerative diseases. Ubiquitin carboxy-terminal hydrolase L1 (UCHL1), an important component of the UPP in the neuron, is covalently modified and its activity inhibited by reactive lipids produced after ischemia. As a result, degradation of toxic proteins is impaired which may exacerbate neuronal function and cell death in stroke and neurodegenerative diseases. Preserving or restoring UCHL1 activity may be an effective therapeutic strategy in stroke and neurodegenerative diseases. PMID- 27702702 TI - Temporarily Blocking the Uterine Artery to Dig Out a Diffused Adenomyosis Lesion Treated Laparoscopically. AB - STUDY OBJECTIVE: To show the tips and tricks of a simpler technique for temporary blocking of the uterine artery in laparoscopic resection of a diffuse adenomyosis lesion to make the procedure more efficient and reproducible. DESIGN: This study is designed to be a step-by-step explanation of the technique using videos and pictures (Canadian Task Force classification III). SETTING: Changzhou Maternal and Child Health Hospital, Changzhou, China. PATIENTS: Three patients (age 39-42 years, 41+/-1.73) were diagnosed with diffuse adenomyosis with severe secondary dysmenorrhea willing to reserve the uterus and a poor response to medical management. Gynecologic examination revealed that the uteri sizes were 9 to 14 weeks. Transvaginal ultrasonography revealed that the lesions were 4 to 7 cm in size. INTERVENTIONS: Laparoscopic resection of the diffuse adenomyosis lesion was conducted after temporary blocking of the uterine artery with a rubber belt. MEASUREMENTS AND MAIN RESULTS: The traditional methods for injecting diluted vasopressin in the myometrium around the affected area and a half-life period of 30 minutes were used. Many adenomyosis patients with severe dysmenorrhea and menometrorrhagia have a large lesion; thus, the operating time is longer. The maximum dose of vasopressin is 20 units daily, and hypertensive patients have a contraindication. We made an incision of the broad ligament of the avascular area near the uterine artery and pulled the rubber pressure pulse ligation tightly through to temporarily block the uterine artery without vasopressin completely through the laparoscopic resection of the diffuse adenomyosis lesion. Intraoperative blood loss was only 120 to 230 mL. In this video, we show a simpler technique for temporarily blocking the uterine artery in laparoscopic resection of diffuse adenomyosis with a stepwise expiation. A levonorgestrel releasing intrauterine system (Mirena; Bayer, Leverkusen, Germany) was placed in the uterus from the vagina immediately after surgery. At the 3-25 month (10.67+/ 12.42) follow-up, visual analog scale scores were obviously reduced, and the menstrual quantity and amenorrhea dramatically declined after the surgery. All patients had no recurrence and no Mirena loss as assessed by vaginal ultrasound and the visual analog scale [1]. Estrogen was maintained at the normal level after 3 months. This study was approved by the Institutional Review Board of the Changzhou Maternal and Child Health Hospital Affiliated to Nanjing Medical University. CONCLUSION: The incidence of adenomyosis is a newer trend that is being used in patients with a poor response to medical management of uterine lesions and large lesions in China. Using the rubber belt to temporarily block the uterine artery in laparoscopic resection of the diffuse adenomyosis lesion offers the possibility of the rubber belt being effective, safe, and reproducible. Minimally invasive surgery in expert hands is the preferred solution of an increasing number of patients after drug treatment failure. PMID- 27702703 TI - Adnexal Torsion in Postmenopausal Women: Clinical Presentation and Risk of Ovarian Malignancy. AB - STUDY OBJECTIVE: To investigate the clinical presentation, operative outcome, and incidence of malignancy in postmenopausal women who were diagnosed with adnexal torsion. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Tertiary university-affiliated hospital. PATIENTS: Postmenopausal women diagnosed with adnexal torsion between 1995 and 2014 (study group) were reviewed and compared with 220 premenopausal patients diagnosed with adnexal torsion during the same time period. INTERVENTION: Demographic data, clinical signs and symptoms, and intra- and postoperative characteristics were compared between the 2 groups. MEASUREMENTS AND MAIN RESULTS: During the study period 44 postmenopausal women were diagnosed with adnexal torsion. Continuous dull pain was the most common presenting symptom in the postmenopausal group (57%), whereas acute-onset sharp pain was the predominant symptom in the premenopausal group (86%). The time interval from admission to surgery was significantly longer in the postmenopausal group (24 vs 6 hours, p < .001). Laparoscopic surgery was performed in 84.5% of the cases in the premenopausal group, whereas it was carried out in only 50% of cases in the postmenopausal group (p < .001). Four women in the postmenopausal group were diagnosed with malignancy, whereas only 1 case of malignancy was found in the premenopausal group (9% vs .4%, respectively; p = .003). CONCLUSIONS: Adnexal torsion in postmenopausal women is an uncommon event with a unique presentation. Because ovarian malignancy is not an uncommon finding in this group of patients, preparation for more extensive surgery should be contemplated. PMID- 27702704 TI - Minimally Invasive Surgical Staging for Ovarian Carcinoma: A Propensity-Matched Comparison With Traditional Open Surgery. AB - STUDY OBJECTIVE: Growing evidence supports the safety of a laparoscopic approach for patients affected by apparent early-stage ovarian cancer. However, no well designed studies comparing laparoscopic and open surgical staging are available. In the present investigation we aimed to provide a balanced long-term comparison between these 2 approaches. DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: Tertiary center. PATIENTS: Data of consecutive patients affected by early-stage ovarian cancer who had laparoscopic staging were matched 1:1 with a cohort of patients undergoing open surgical staging. The matching was conducted by a propensity-score comparison. INTERVENTION: Laparoscopic and open surgical staging. MEASUREMENTS AND MAIN RESULTS: Fifty patient pairs (100 patients: 50 undergoing laparoscopic staging vs 50 undergoing open surgical staging) were included. Demographic and baseline oncologic characteristics were balanced between groups (p > .2). We observed that patients undergoing laparoscopic staging experienced longer operative time (207.2 [71.6] minutes vs 180.7 [47.0] minutes; p = .04), lower blood loss (150 [52.7] mL vs 339.8 [225.9] mL; p < .001), and shorter length of hospital stay (4.0 [2.6] days vs 6.1 [1.6] days; p < .001) compared with patients undergoing open surgical staging. No conversion to open surgery occurred. Complication rate was similar between groups. No difference in survival outcomes were observed, after a mean (SD) follow-up of 49.5 (64) and 52.6 (31.7) months after laparoscopic and open surgical staging, respectively. CONCLUSIONS: Our findings suggest that the implementation of minimally invasive staging does not influence survival outcomes of patients affected by early-stage ovarian cancer. Laparoscopic staging improved patient outcomes, reducing length of hospital stay. Further large prospective studies are warranted. PMID- 27702705 TI - Robotic-assisted Reconstruction of the Cervix and Vagina by Small Intestinal Submucosa Graft and Fusion of the Hemiuterus. AB - STUDY OBJECTIVE: To describe our technique of robotic-assisted reconstruction of the cervix and vagina using a small intestinal submucosa (SIS) graft and fusion of the hemiuterus. DESIGN: A step-by-step explanation of the procedure using video. SETTING: Congenital complete vaginal and cervical atresia is rare. Some patients have urinary system abnormality. No standardized surgical treatment guideline was available, and the performance varies for each patient. INTERVENTIONS: We performed a robotic-assisted reconstruction of the cervix and vagina using an SIS graft (Cook Medical, Bloomington, IN) and fusion of the hemiuterus for a 12-year-old girl from China diagnosed with congenital vaginal and cervical atresia (U4C4V4). She complained of severe abdominal periodic pain for 2 months. Mammary development and her serum sex hormone were within normal range. The patient has a single kidney. The diagnosis was made according to clinical characteristics, physical examination, and magnetic resonance imaging and classified using the European Society of Human Reproduction and Embryology /European Society for Gynaecological Endoscopy (ESHRE/ESGE) system. There was a hematometra of 7-cm diameter in her pelvis. We constructed a novel vagina by sharp and blunt separation and connected it to the uterine cavity. With the SIS graft, we reconstructed her cervix and vagina, and we fused the hemiuterus to make the uterine cavity spacious. The operating time was 260 minutes, and blood loss was 300 mL. She recovered well after the operation without any complications. After surgery, the patient has had normal menstruation without pain. She insists on wearing the vaginal mold 24 hours per day. The follow-up was 10 months. The length of the vagina was 9 cm and the width was 3 cm. CONCLUSION: Robotic-assisted reconstruction of the cervix and vagina using an SIS graft and fusion of the hemiuterus is feasible and safety. However, additional studies are required. PMID- 27702706 TI - Radiosurgery for Secondary Trigeminal Neuralgia: Revisiting the Treatment Paradigm. AB - BACKGROUND: The mechanisms by which surgery and radiation elicit pain relief in trigeminal neuralgia (TN) secondary to mass lesions vary widely. We aimed to evaluate the outcomes of radiation to the nerve rather than to the lesion in the treatment of secondary TN. METHODS: We retrospectively reviewed all patients who underwent radiation at the University of California, Los Angeles for TN secondary to tumors. The Barrow Neurological Institute (BNI) pain score was used to evaluate pain outcomes. RESULTS: Twelve patients were identified; 4 were male and 8 were female. Their mean age at treatment was 59.8 years (range, 47.7-84.7 years). Tumor pathologies included meningioma (n = 8), squamous cell carcinoma (n = 2), vestibular schwannoma (n = 1), and hemangiopericytoma (n = 1). No patient suffered from multiple sclerosis. Ten patients underwent initial radiation targeting their tumors-radiosurgery in 3 and fractionated radiation therapy in 7 others. Only 6 among these 10 experienced at least partial relief, which lasted a mean 6 months. Radiosurgery targeting the trigeminal nerve was eventually performed. Overall, 10 of 12 (83.3%) patients experienced good initial pain relief, complete in 6 (50%) patients. Pain recurred in 6 (60%) patients, at a mean 41 months after radiosurgery to the trigeminal nerve. Three patients experienced facial sensory dysfunction postprocedurally at a mean follow-up duration of 57 months. CONCLUSION: In contrast to tumor radiation, radiosurgery to the trigeminal nerve root resulted in reasonable and longer pain reduction, on par with the literature regarding surgical resection, with low risk of additional complications. PMID- 27702707 TI - Bilateral Chronic Subdural Hematoma Treated by YL-1 Type Hematoma Aspiration Needle Complicated by Hemorrhage of the Basal Ganglia and Brainstem. AB - BACKGROUND: A 72-year-old man with bilateral chronic subdural hematomas was admitted to our department and treated using a YL-1 type hematoma aspiration needle. The treatment was complicated by hemorrhage of the basal ganglia and brainstem. This patient had no history of hypertension. We evaluated the relevant literature to analyze the causes of cerebral hemorrhage in similar patients. CONCLUSIONS: This case report illustrates that the stability of the intracranial pressure should be closely monitored during the surgical treatment of chronic subdural hematomas, and large fluctuations in the cerebral perfusion pressure should be avoided during the operation. We also propose improvements in the technical details of the operative treatment of chronic subdural hematomas. PMID- 27702708 TI - Neurophysiology of myoclonus and progressive myoclonus epilepsies. AB - The high temporal resolution of neurophysiological recordings makes them particularly suited to faithfully describing the time course of rapid events such as myoclonus and to precisely measure its time relationship with other related activities. In progressive myoclonus epilepsies (PMEs) polygraphy with simultaneous EMG-EEG recordings is a crucial tool for defining the characteristic of myoclonic jerks their topography over different muscles (namely antagonists), their time course and relationship with vigilance muscle activation and stimulations. Moreover on polygraphic recordings it is possible to detect EEG activities associated to myoclonic jerks and define their time relationship with myoclonus thus differentiating cortical types of myoclonus from subcorticallly generated ones. Tanks to the back averaging technique non obvious time-locked EEG potentials can be detected on polygraphy , furthermore in stimulus sensitive myoclonus the analysis can include the potential evoked by the somatosensory stimulus (SEP). The polygraphic recording also gives information on muscle activity suppression occurring after jerk or as pure negative myoclonus. Besides the time domain analysis, techniques based on frequency analysis have been developed to evaluate EEG-EMG coherence. The neurophysiological techniques provide investigators and clinicians with an invaluable information to define the type of myoclonus and its generating circuitry thus substantially contributing in the diagnosis and management of PMEs. PMID- 27702710 TI - Fructans in the first 1000 days of life and beyond, and for pregnancy. AB - Inulin-based prebiotics are non-digestible polysaccharides that influence the composition of the gut microbiota in infants and children, notably eliciting a bifidogenic effect with high short chain fatty acid levels. Inulin, a generic term that comprises beta-(2,1)-linked linear fructans, is typically isolated from the chicory plant root, and derivatives such as oligofructose and long chain inulin appear to have different physiological properties. The first 1000 days of a child's life are increasingly recognized as a critical timeframe for health also into adulthood, whereby nutrition plays a key role. There is an ever increasing association between nutrition and gut microbiota composition and development, with life health status of an individual. This review summarizes the latest knowledge in the infant gut microbiota from preterms to healthy newborns, as well as in malnourished children in developing countries. The impact of inulin or mixtures thereof on infants, toddlers and young children with respect to intestinal function and immunity in general, is reviewed. Possible benefits of prebiotics to support the gut microbiome of malnourished infants and children, especially those with infections in the developing world, are considered, as well as for the pregnant mothers health. Importantly, novel insights in metabolic programming are covered, which are being increasing recognized for remarkable impact on long term offspring health, and eventual potential beneficial role of prebiotic inulins. Overall increasing findings prompt the potential for gut microbiota-based therapy to support health or prevent the development of certain diseases from conception to adulthood where inulin prebiotics may play a role. PMID- 27702709 TI - Lafora disease. AB - Lafora disease (LD) is an autosomal recessive progressive myoclonus epilepsy due to mutations in the EPM2A (laforin) and EPM2B (malin) genes, with no substantial genotype-phenotype differences between the two. Founder effects and recurrent mutations are common, and mostly isolated to specific ethnic groups and/or geographical locations. Pathologically, LD is characterized by distinctive polyglucosans, which are formations of abnormal glycogen. Polyglucosans, or Lafora bodies (LB) are typically found in the brain, periportal hepatocytes of the liver, skeletal and cardiac myocytes, and in the eccrine duct and apocrine myoepithelial cells of sweat glands. Mouse models of the disease and other naturally occurring animal models have similar pathology and phenotype. Hypotheses of LB formation remain controversial, with compelling evidence and caveats for each hypothesis. However, it is clear that the laforin and malin functions regulating glycogen structure are key. With the exception of a few missense mutations LD is clinically homogeneous, with onset in adolescence. Symptoms begin with seizures, and neurological decline follows soon after. The disease course is progressive and fatal, with death occurring within 10 years of onset. Antiepileptic drugs are mostly non-effective, with none having a major influence on the progression of cognitive and behavioral symptoms. Diagnosis and genetic counseling are important aspects of LD, and social support is essential in disease management. Future therapeutics for LD will revolve around the pathogenesics of the disease. Currently, efforts at identifying compounds or approaches to reduce brain glycogen synthesis appear to be highly promising. PMID- 27702711 TI - Optimal nutrition therapy in paediatric critical care in the Asia-Pacific and Middle East: a consensus. AB - BACKGROUND AND OBJECTIVES: Current practices and available resources for nutrition therapy in paediatric intensive care units (PICUs) in the Asia Pacific Middle East region are expected to differ from western countries. Existing guidelines for nutrition management in critically ill children may not be directly applicable in this region. This paper outlines consensus statements developed by the Asia Pacific-Middle East Consensus Working Group on Nutrition Therapy in the Paediatric Critical Care Environment. Challenges and recommendations unique to the region are described. METHODS AND STUDY DESIGN: Following a systematic literature search from 2004-2014, consensus statements were developed for key areas of nutrient delivery in the PICU. This review focused on evidence applicable to the Asia Pacific-Middle East region. Quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation approach. RESULTS: Enteral nutrition (EN) is the preferred mode of nutritional support. Feeding algorithms that optimize EN should be encouraged and must include: assessment and monitoring of nutritional status, selection of feeding route, time to initiate and advance EN, management strategies for EN intolerance and indications for using parenteral nutrition (PN). Despite heterogeneity in nutritional status of patients, availability of resources and diversity of cultures, PICUs in the region should consider involvement of dieticians and/or nutritional support teams. CONCLUSIONS: Robust evidence for several aspects of optimal nutrition therapy in PICUs is lacking. Nutritional assessment must be implemented to document prevalence and impact of malnutrition. Nutritional support must be given greater priority in PICUs, with particular emphasis in optimizing EN delivery. PMID- 27702712 TI - Melamine-contaminated milk formula and its impact on children. AB - The melamine contaminated milk powder contamination scandal occurred in China in 2008. Its main consequences so far have been urinary stone formation in children with associated renal damage and increased child mortality. Eight years have passed, but food safety issues still remain of concern in the daily lives of millions of Chinese. Vigilance is required to ensure no recurrence of such food safety problems. Ongoing studies focus on the early detection of food industry malpractice, mechanisms whereby these toxic substances induce disease and how its advent may be prevented and better managed. Melamine undergoes renal excretion, but is metabolized slowly and excreted largely unchanged in the urine. Urinary melamine measurement may provide a rapid and inexpensive way to identify exposure to melamine adulterated food items. Although most patients with melaminerelated urinary stones (MUS) have been responsive to conservative treatment, longer time follow-up is needed to assess chronic effects. Aside from MUS, melamine is a recognized carcinogen and can induce urinary tract tumours. Very little is known about the effects of excessive exposure to melamine contaminated milk powder in infants on growth, adolescent and adult health, although short-term effects have become apparent during the scandal. PMID- 27702713 TI - Future food. AB - Food systems have changed markedly with human settlement and agriculture, industrialisation, trade, migration and now the digital age. Throughout these transitions, there has been a progressive population explosion and net ecosystem loss and degradation. Climate change now gathers pace, exacerbated by ecological dysfunction. Our health status has been challenged by a developing people environment mismatch. We have regarded ecological conquest and innovative technology as solutions, but have not understood how ecologically dependent and integrated we are. We are ecological creatures interfaced by our sensoriness, microbiomes, shared regulatory (endocrine) mechanisms, immune system, biorhythms and nutritional pathways. Many of us are 'nature-deprived'. We now suffer what might be termed ecological health disorders (EHD). If there were less of us, nature's resilience might cope, but more than 9 billion people by 2050 is probably an intolerable demand on the planet. Future food must increasingly take into account the pressures on ecosystem-dependent food systems, with foods probably less biodiverse, although eating in this way allows optimal health; energy dysequilibrium with less physical activity and foods inappropriately energy dense; and less socially-conducive food habits. 'Personalised Nutrition', with extensive and resource-demanding nutrigenomic, metabolomic and microbiomic data may provide partial health solutions in clinical settings, but not be justified for ethical, risk management or sustainability reasons in public health. The globally prevalent multidimensional malnutritional problems of food insecurity, quality and equity require local, regional and global action to prevent further ecosystem degradation as well as to educate, provide sustainable livelihoods and encourage respectful social discourse and practice about the role of food. PMID- 27702714 TI - Children with atopic dermatitis in Daejeon, Korea: individualized nutrition intervention for disease severity and nutritional status. AB - BACKGROUND AND OBJECTIVES: Atopic dermatitis is one of the most common pediatric chronic inflammatory skin diseases, and certain food allergens and nutrients are closely related to the development and severity of atopic dermatitis. While avoidance of the causative foods is considered the mainstay of treatment, unverified excessive restriction might induce unnecessary limitations in the food intake, consequently leading to nutritional deficiencies and poor growth. This study aimed to identify the characteristics and nutrient intake status in children with atopic dermatitis and to investigate the effects of individualized nutrition intervention. METHODS AND STUDY DESIGN: We retrospectively reviewed electronic medical records of 77 pediatric patients with atopic dermatitis who received 4 months of individualized nutrition intervention combined with an elimination diet. The patient characteristics, nutrient intake status, and clinical status were examined before and after the intervention. RESULTS: Before the intervention, 5 children had a weight for height z-score below -2.0, and 48.1% had experienced food restriction; these children showed a significantly higher SCORing of Atopic Dermatitis index than those without experiences, with the number of restricted foods before the intervention positively correlating with the disease severity. The intakes of n-6 and n-3 fatty acids, calcium, folate, and vitamin D were lower than the recommended nutrient intakes for Koreans. After the intervention, the weight for height z-score of 35 children was significantly increased and their SCORing of Atopic Dermatitis index was significantly reduced (p<0.05). CONCLUSIONS: Individualized nutrition intervention appears useful for alleviating the severity of atopic dermatitis and improving the growth status by improving the nutrient intake. PMID- 27702716 TI - Enteral nutrition preference in critical care: fibre-enriched or fibre-free? AB - BACKGROUND AND OBJECTIVES: This study's main aim was to observe the effects of a fibre-enriched nutrition solution on requisite feeding volume, which is directly proportional to energy intake in mechanically ventilated patients with enteral nutrition. METHODS AND STUDY DESIGN: Some 120 patients who required mechanical ventilation and enteral nutrition with a nasogastric tube were studied. Upon ICU admission, the patient's age, gender, weight, height, comorbidities, diagnosis and APACHE II score were recorded. We assigned two diets to the patients randomly. The control group received the fibre-free nutrition solution. The study group, received the fibreenriched nutrition solution. Prescribed feeding volume and administered feeding volume, gastric residual volume (GRV), volume ratio (VR), diarrhoea score and gastrointestinal complications (GIC) were recorded, along with daily biochemistry. RESULTS: The two groups did not differ with respect to age, sex, weight, BMI, APACHE II score, target caloric intake or GRV (p>0.05). On days four and five, the study group had higher VR values (p<0.05). Seventy-one (59%) patients had at least one gastrointestinal complication; 44 (73%) of them were controls and 27 (45%) of them study patients. The most commonly observed GIC was diarrhoea. Thirty-eight patients had diarrhoea in control group, and twenty-two patients had diarrhoea in study group, and this difference was statistically significant (p<0.001). There were no significant differences between the groups about vomiting and regurgitation. CONCLUSIONS: We suggest that ICU staff initiate enteral nutrition with fibre-enriched formulas rather than fibre-free formulas to avoid frequent feeding interruptions that cause protein energy malnutrition in ICU patients. PMID- 27702715 TI - Simultaneous coffee caffeine intake and sleep deprivation alter glucose homeostasis in Iranian men: a randomized crossover trial. AB - BACKGROUND AND OBJECTIVES: Sleep deprivation and coffee caffeine consumption have been shown to affect glucose homeostasis separately, but the combined effects of these two variables are unknown. METHODS AND STUDY DESIGN: Forty-two healthy Iranian men, aged 20-40 years old, were assigned to three groups in a randomised crossover trial involving three treatments with two-week washout periods. Subjects were moderate coffee consumers (<=3 cups/day), and had a Pittsburgh Sleep Quality Index <=5. Each treatment involved three nights of deprived sleep (4 hrs. in bed) plus 3*150 cc/cup of boiled water (BW treatment), decaffeinated coffee (DC treatment, without sugar, 99.9% caffeine-free), and caffeinated coffee (CC treatment, without sugar, 65 mg caffeine/ cup). DC and CC treatments were blinded. At the end of each treatment, fasting serum glucose (using enzyme assays) and insulin (using electrochemiluminescence immunoassay) were measured and, again, two hours after an oral glucose tolerance test (OGTT). Insulin resistance was quantified with the homeostasis model. RESULTS: Repeated measures ANOVA indicated no significant difference between the treatments in fasting serum glucose (p=0.248) or insulin resistance (p=0.079). However, ANOVA demonstrated differences between treatments in fasting serum insulin (p=0.004) and glucose, as well as insulin after OGTT (p<0.001). Pairwise comparisons test (within subjects) showed that the CC treatment yielded higher serum glucose and insulin after OGTT (p<0.001), higher fasting serum insulin (p=0.001), and increased insulin resistance (p=0.039) as compared to the DC treatment. CONCLUSIONS: Thus caffeinated coffee was more adverse for glucose homeostasis compared to decaffeinated coffee in individuals who were simultaneously sleep deprived. PMID- 27702717 TI - Combined chromium and magnesium decreases insulin resistance more effectively than either alone. AB - BACKGROUND AND OBJECTIVES: Peroral supplementation with trivalent-chromium (Cr) or magnesium (Mg) has been shown to improve insulin resistance (IR). The objective of this study was to determine whether combined peroral supplementation with Cr and Mg improves IR more effectively than Cr or Mg alone. METHODS AND STUDY DESIGN: Subjects (n=120, age range 45-59 years old) and diagnosed with IR were randomly divided into four groups and monitored for a period of 3 months: group 1 (the placebo control group), group 2 (160 MUg/d Cr), group 3 (200 mg/d Mg), and group 4 (160 MUg/d Cr plus 200 mg/d Mg). Fasting blood glucose (FBG), fasting insulin (FIns), erythrocyte Cr and Mg content, and glucose-transporter-4 (GLUT4) and glycogen-synthase-kinase-3beta (GSK3beta) mRNA levels in activated T lymphocytes were measured, and insulin resistant index (IRI) was calculated. RESULTS: Significant decreases between the baseline and study conclusion values of FBG (0.37 mmol/L, p<0.01), FIns (2.91 MUIU/mL, p<0.01) and IRI (0.60, p<0.01) were observed in group 4, but not groups 1-3. Similarly, compared with baseline, significant changes in GLUT4 (2.9-fold increase, p<0.05) and GSK3beta (2.2-fold decrease, p<0.05) mRNA levels in activated T-lymphocyte were observed at the study's conclusion in group 4, but not in groups 1-3. CONCLUSIONS: Our results indicate that combining peroral supplementation with Cr and Mg improves IR more effectively than Cr or Mg alone, and this may be attributable to increased induction and repression, respectively, of GLUT4 and GSK3beta expression. PMID- 27702718 TI - 25 hydroxy vitamin D is higher when a renal multivitamin is given with cholecalciferol at hemodialysis. AB - BACKGROUND AND OBJECTIVES: Seventy six hemodialysis (HD) patients were used in a prospective randomized and clinical trial to determine if a multivitamin with vitamin D (cholecalciferol 12,000 IU/week) given during dialysis would improve the vitamin D status of hemodialysis subjects. METHODS AND STUDY DESIGN: Subjects were randomly assigned to two groups: 37 subjects were in the renal multivitamin without vitamin D (MV) group and 39 subjects were in a multivitamin route with vitamin D (MVD) group (12,000 IU of cholecalciferol per week). All subjects were given 2 multivitamin tablets at their 3 HD sessions each week for 20 weeks. Serum 25(OH)D, calcium (Ca), and phosphorus (P) levels were evaluated. RESULTS: At baseline, mean serum 25(OH)D were below adequate (<30 ng/mL) in the MV group (23.5+/-12.2 ng/mL) and in the MVD group (20.8+/-10.3 ng/mL). A significant increase was seen in serum 25(OH)D levels (37.7+/-11.4 ng/mL; p<0.001) in the MVD group after vitamin D supplementation with no rise in the MV group value (21.7+/ 11.4 ng/mL; p=0.06). Prior to supplementation, 17.9% of patients in the MVD group had adequate serum 25(OH)D level and post supplementation 76.9% in the MVD group had adequate serum 25(OH)D. In the MV group, 18.9% subjects had adequate serum 25(OH)D levels at baseline with 18.9% having 25(OH)D >30 ng/mL at the end of the study. There were no significant differences in group values for serum Ca and P. CONCLUSION: The majority of HD subjects given a multivitamin with cholecalciferol at dialysis had improvement in their vitamin D status. PMID- 27702719 TI - Cod skin peptide reduces chemotherapy-induced toxicity in gastric cancer patients. AB - BACKGROUND AND OBJECTIVES: The present study was conducted to evaluate the effect of cod skin peptide (CSPE) on chemotherapy-induced toxicity in gastric cancer patients. METHODS AND STUDY DESIGN: A cohort of 60 gastric cancer patients for chemotherapy was randomly divided into two groups (n=30 per group), who were orally treated with either supplemental CSPE or placebo apart from chemotherapy. The hematologic and gastrointestinal toxicities experienced by the patients, as well as their Karnofsky Performance Status (KPS) as an index of quality of life was evaluated. RESULTS: Leukocyte counts and haemoglobin levels were significantly reduced in the group treated with peptide (p<0.05), while gastrointestinal toxicity was not affected (p>0.05). KPS consists of 11 categories of quality of life, and the score denoted in deciles ranges from 100 (asymptomatic, normal function) to 0 (death). The KPS score is used to evaluate a cancer patient's ability to function at work and home, the severity of symptoms, and the patient's need for personal and medical care. Treatment with CSPE significantly improved the quality of life of patients, as indicated by increased KPS scores (p<0.05). CONCLUSIONS: CSPE can potentially be considered as a food supplement that can be used to improve the quality of life of cancer patients. PMID- 27702720 TI - Coffee consumption is associated with lower serum aminotransferases in the general Korean population and in those at high risk for hepatic disease. AB - BACKGROUND AND OBJECTIVES: The favourable effects of coffee on liver enzymes have been reported worldwide. This study investigated the association between coffee consumption and serum aminotransferase concentration in Korean adults. METHODS AND STUDY DESIGN: Data were obtained from the fourth and fifth Korea National Health and Nutrition Examination Surveys. Elevated alanine aminotransferase (ALT) and aspartate aminotransferase (AST) concentration were defined as >30 IU/L for men and >19 IU/L for women. The risk of elevated ALT and AST according to general characteristics and frequency of coffee consumption were tested by chi-square tests and multiple logistic regression analyses. RESULTS: The prevalence of elevated ALT was 27.4%, 27.8%, and 26.9% in subjects who drank <1, 1, and >=2 times/day, respectively. The proportions of individuals with elevated AST were 32.5%, 33.1%, and 26.7% in subjects who drank <1, 1, and >=2 times/day, respectively. The aORs for elevated ALT and AST were significantly lower in subjects who drank >=2 times of coffee/day than in those who drank <1 time/day (ALT: aOR=0.86, 95% CI=0.79-0.94; AST: aOR=0.83, 95% CI=0.76-0.91). In subgroup analysis, consumption of >=2 times/day was associated with lower ORs for elevated ALT in the high-risk group overall and in the viral hepatitis and obesity subgroups, respectively. In sensitivity analysis, reduced frequency of coffee consumption was associated with an increased risk for elevated liver enzymes, although an association between coffee consumption and elevated ALT was not observed in women or current smokers. CONCLUSIONS: Higher coffee consumption was associated with lower risk of elevated aminotransferase concentration in Korean adults. PMID- 27702721 TI - Habitual dietary calcium intakes and calcium metabolism in healthy adults Chinese: a systematic review and meta-analysis. AB - To investigate the metabolic differences of calcium requirements between Chinese and Westerners, we examined systematically the characteristics of calcium metabolism in Chinese adults with habitual dietary calcium intakes. We searched PubMed, Cochrane Library, SinoMed, and National Index to Chinese Newspapers & Periodicals, from inception to March 17, 2015, as well as the bibliographies of any relevant papers and journals, for trials assessing calcium metabolism in healthy Chinese adults within 18-60 years of age on the typical Chinese diet. We extracted a standardized dataset from metabolic studies that reported intake, retention, urinary excretion, faecal excretion and/or fractional absorption of calcium. We pooled data with a random effects meta-analysis. Of 2,046 citations identified by the search strategy, 12 studies (comprising 137 participants, 13 aggregate data deriving from 257 individual data) met the inclusion criteria. Metabolic data with self-chosen or typical Chinese diets were analyzed. Mean daily intakes of calcium ranged between 288 and 948 mg. Mean calcium retentions of each study were between 13 and 294 mg/d. The overall pooled value for dietary intake, urinary excretion, faecal excretion, retention and fractional absorption of calcium were 583 mg/d, 117 mg/d, 381 mg/d, 72 mg/d and 33.3%. Dietary calcium intake and faecal calcium excretion explained almost 85% of the heterogeneity of calcium retention. Chinese adults could maintain a positive calcium balance with plant-based diets at calcium intakes as low as 300 mg/d through increasing fractional calcium absorption and decreasing calcium excretion in urine and faeces. PMID- 27702722 TI - Population-based association between urinary excretion of sodium, potassium and its ratio with albuminuria in Chinese. AB - BACKGROUND AND OBJECTIVES: Albuminuria is a risk factor for cardiovascular and renal disease. However, little is known about the association of 24 h urinary sodium and potassium excretion with albuminuria in China. The aim of this study was to examine this association by analyzing the data from 1,975 Chinese adults living in north China. METHODS AND STUDY DESIGN: Excretion of urinary sodium, potassium and albumin was assessed in a single 24-h urine sample for each participant. Height, weight, waist circumference and blood pressure were measured and body mass index was determined as weight divided by square height. Fasting blood sample was collected and fasting glucose was measured. RESULTS: The average 24-h urinary sodium and potassium excretion were 232 mmol and 40.8 mmol, resulting a mean sodium to potassium ratio of 6.7. The median (Q1-Q3) 24-h urinary albuminuria excretion was 6.1 mg (4.5-8.7 mg). Overall, urinary sodium excretion was positively associated with albumin excretion (beta=0.029, p<0.001). This association was independent of major cardiovascular risk factors including age, gender, systolic blood pressure, body mass index, fasting glucose, waist circumference, hypertensive drug treatment, and smoking. Moreover, the relation of sodium and albumin was similar in the subgroups stratified by gender, adiposity and diabetic status. No significant associations of potassium excretion or sodium to potassium ratio with urinary albumin excretion were observed. CONCLUSIONS: In cross-sectional analyses, high sodium intake was shown to be associated with increased urinary albuminuria in the general Chinese adult population, supporting salt restriction for renal and cardiovascular health benefit. PMID- 27702723 TI - Truncal and leg fat associations with metabolic risk factors among Chinese adults. AB - BACKGROUND AND OBJECTIVES: To examine the associations of regional body fat distribution with metabolic risk factors among Chinese. METHODS AND STUDY DESIGN: Truncal fat (TF) and leg fat (LF) were measured by dualenergy X-ray absorptiometry (DXA) among 947 adults, and abdominal visceral fat (VAT) and subcutaneous fat (SAT), upper leg SAT were measured by magnetic resonance image (MRI) among 103 adults during 2008-2013. Metabolic risk factors included fasting blood glucose, total triglyceride, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and metabolic syndrome (MetS). RESULTS: TF showed adverse effect while LF showed beneficial effect on metabolic risk factors, and all these effects were independent of body mass index (BMI) (mostly p<0.01). Individuals with higher TF and lower LF experienced the highest risk of MetS compared to other subgroups of combination of TF and LF (all p<0.05). Abdominal VAT was positively associated with risk of MetS (men: odds ratio (OR)=4.45, 95% confidence interval (CI): 1.18, 16.8; women: OR=6.54, 95% CI: 1.08, 39.6) and serum triglyceride (men: beta (beta)=0.379, 95% CI: 0.090, 0.667; women: beta=0.700, 95% CI: 0.327, 1.07). Upper leg SAT showed an opposite association with most metabolic factors compared to abdominal SAT and VAT, however, the association was not statistically significant. CONCLUSION: TF and LF showed opposite effects on metabolic risk factors among Chinese adults. Abdominal VAT, but not abdominal SAT, was positively associated with serum triglyceride and risk of MetS. Future studies are warranted to examine the potential mechanism of the opposite effects between TF and LF on metabolic risk factors among Chinese. PMID- 27702724 TI - Pre-pregnancy body mass index and gestational weight gain in Thai pregnant women as risks for low birth weight and macrosomia. AB - BACKGROUND AND OBJECTIVES: Maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) have been reported to be associated with pregnancy outcomes. Due to the nutrition transition in Thailand, the double burden of malnutrition is increasing and this may have negative consequences on birth outcomes. This study aimed to investigate the relationship between pre-pregnancy BMI and GWG with the risks of low birth weight and macrosomia. METHODS AND STUDY DESIGN: We performed a secondary analysis of data obtained from an iodine supplementation trial in mildly iodine-deficient Thai pregnant women. Pre pregnancy BMI was classified using the WHO classification. GWG was categorized using the IOM recommendation. Binary and multinomial logistic regressions were performed. RESULTS: Among 378 pregnant women, the prevalence of pre-pregnancy underweight (BMI<18.5 kg/m2) and overweight (BMI>=25 kg/m2) were 17.2% and 14.3%, respectively. Normal weight women had the highest median GWG [15.0 (12.0, 19.0) kg] when compared to overweight women [13.2 (9.0, 16.3) kg]. Forty-one percent of women had excessive GWG, while 23% of women gained weight inadequately. Women with a high pre-pregnancy BMI had a 7-fold higher risk of having a macrosomic infant. Women who had excessive GWG were 8 times more likely to deliver a newborn with macrosomia. CONCLUSIONS: Both high pre-pregnancy maternal weight and excessive weight gain during pregnancy increase risk of infant macrosomia. Therefore, maintaining normal body weight before and throughout pregnancy should be recommended in order to reduce the risk of excessive infant birth weight and its associated complications. PMID- 27702725 TI - An on-line database for human milk composition in China. AB - BACKGROUND AND OBJECTIVES: Understanding human milk composition is critical for setting nutrient recommended intakes (RNIs) for both infants and lactating women. However, nationwide human milk composition remains unavailable in China. METHODS AND STUDY DESIGN: Through cross-sectional study, human milk samples from 11 provinces in China were collected and their compositions were analyzed. Nutritional and health status of the lactating women and their infants were evaluated through questionnaire, physical examination and biochemical indicators. RESULTS: A total of 6,481 breast milk samples including colostrum (1,859), transitional milk (1,235) and mature milk (3,387) were collected. Contents of protein, fat, lactose, total solid and energy of more than 4,500 samples were analyzed using a human milk analyzer. About 2,000 samples were randomly selected for 24 mineral analyses. Free B-vitamins including thiamin, riboflavin, pyridoxal, pyridomine, pyridoxamine, nicotinamide, nicotinic acid, flavin adenine dinucleotide (FAD), biotin and pantothenic acid were analyzed in 1,800 samples. Amino acids (~800) and proteins (alpha-lactoalbumin, beta-casein, and lactoferrin) were analyzed. In addition, serum retinol and carotenoids, 25(OH)D, vitamin B-12, folic acid, ferritin and biochemical indicators (n=1,200 to 2,000) were analysed in the lactating women who provided the breast milk. Ongoing work: Fatty acids (C4-C24), fatsoluble vitamins and carotenoids, are on-going analysis. CONCLUSIONS: A regional breast milk compositional database is at an advanced stage of development in China with the intention that it be available on-line. PMID- 27702727 TI - An internet-based food frequency questionnaire for a large Chinese population. AB - BACKGROUND AND OBJECTIVES: National dietary surveys are needed and difficult to conduct in China. The current study aims to develop and validate an internet based diet questionnaire for Chinese (IDQC) to assess intakes in Northern China. METHODS AND STUDY DESIGN: We recruited 292 city residents by email and telephone in Harbin to obtain the IDQC and 3-day diet diaries. The food group and nutrient intakes from the IDQC were validated against those from the 3-day diet diaries. Paired sample t-tests were used to compare the methodological differences, and repeatability was estimated using Pearson's correlations. Cross-classification was used to calculate the percentage agreement in quartiles for all food groups and nutrients. RESULTS: Positive correlations were found between the IDQC and 3 day diet diaries for all food groups after energy adjustment (from 0.28 for seeds and nuts to 0.63 for dairy products). Positive correlations were observed for all nutrients between the IDQC and 3-day diet diaries, with correlations ranging from 0.37 for folic acid to 0.98 for iodine. The overall agreements for food groups and nutrients were above 69.2%, indicating satisfactory consistency between the IDQC and 3-day diet diaries. CONCLUSIONS: The IDQC can be used to estimate the food and nutrient intakes in a Northern China population for both clinical nutrition epidemiological and public health nutritional purposes. The questionnaire system IDQC (v1.0) is freely available at http://www.yyjy365.org/diet/. PMID- 27702726 TI - Obesity, non-communicable disease (NCD) risk factors and dietary factors among Chinese school-aged children. AB - BACKGROUND AND OBJECTIVES: China's nutrition transition is characterized by dramatic increases in overweight and cardiometabolic (CM) risk. The burden of obesity, CM risk factors and dietary intake among Chinese children were explored. METHODS AND STUDY DESIGN: Children 7-12 y old from the 2009 China Health and Nutrition Survey with available dietary intake data, anthropometry, blood pressure, and fasting blood samples were included (n=663). CM risk prevalence was calculated; logistic regression was used to investigate the association of nutrient intakes with CM risk, adjusting for age, gender, physical activity, area of residence and income. RESULTS: 14% of Chinese school-aged children and ~20% of those from urban areas and higher income households had overweight/obesity (p<0.05). The prevalence of prehypertension was ~20% while hypertension was 14%. Around 20% of all children and >=30% of those from urban areas and higher income households had impaired glucose/ HbA1c (p<0.05). More than half of the studied children had pre-dyslipidemia (i.e. at least one lipid measurement above borderline levels) and 21% of children had dyslipidemia. Approximately 30% of all children had energy intakes above requirements and 38% of them had excessive proportions of dietary fat and saturated fat. Children with higher intakes of total daily energy and total and added sugars had a greater likelihood of having impaired blood pressure and glucose/HbA1c. CONCLUSIONS: Childhood overweight and CM risk is prevalent in urban and rural areas of China and across different socioeconomic groups although disparities between classes still pervade. Several dietary factors such as sugars were significant correlates of CM risk. PMID- 27702728 TI - Dietary attitudes and behaviours of women in China after the 2008 Wenchuan earthquake in three seismically different zones. AB - BACKGROUND AND OBJECTIVES: The sudden occurrence of the 2008 Wenchuan Earthquake not only devastated people's health, but also may have impacted on the psychological and dietary attitudes and behaviours of the survivors. Although the influence of natural disaster on people's health has been extensively investigated, there is a lack of information about the effects on people's dietary attitudes and behaviours. Our aim was to evaluate the influence of the Wenchuan earthquake on the dietary attitudes and behaviours of adult women from different zones of China in July 2008. METHODS AND STUDY DESIGN: 736 women, aged 18-55 years old, were randomly selected and interviewed after the earthquake. Women were selected from three zones: the earthquake zone (n=206), the shaking zone (n=326), and the non-seismic zone (n=204). RESULTS: Although nutrition knowledge mean scores of women in the three zones were relatively low, the women in the earthquake zone became more vigilant about the nutritional value and acceptability of food than women in the other two zones. Nevertheless, women in the earthquake zone also developed some arguably untoward, if understandable, behaviour after the disaster. They increased their consumption and tendency to stock instant food and snack items. That said, these findings were modulated by other factors such as age, residence, Body Mass Index (BMI), and nutrition knowledge itself, as were post-earthquake eating behaviours, as judged by the ordinal logistic regression analyses performed. CONCLUSIONS: The major Wenchuan earthquake was associated with differentials in dietary attitudes and behaviours among women by seismic zone.

AB - BACKGROUND AND OBJECTIVES: Although food hypersensitivity is a public health concern, its documentation among the elderly is limited. The current study aims to compare the prevalence and characteristics of food hypersensitivity among adolescent women between aged 18-24 with among older women >50 years of age. METHODS AND STUDY DESIGN: 660 female university students between the ages of 18 and 24 who volunteered were enrolled as adolescent subjects. 470 women >50 years old who visited the Health Care Centre of Kyoto Katsura Hospital for health check ups were enrolled as the older subjects. A questionnaire created by ourselves asking the presence of food hypersensitivity, symptoms, causative food, personal or family history of other allergic disorders was distributed. RESULTS: The prevalence of food hypersensitivity was statistically similar between adolescent (8.2%) and older women (8.9%). Among them, only 24.1% of the adolescent women and 26.2% of the older women had been diagnosed by physicians as having food allergy. The main causative foods (fruits, shellfish and fish) and the manifestations relating to food hypersensitivity were almost identical between adolescent and older women. In both adolescent and older women, food hypersensitivity positive group showed significantly higher prevalence of personal or family history of allergic disorders than that in food hypersensitivity negative group. CONCLUSIONS: These data indicate that food hypersensitivity in older women should be given more attention because the prevalence of this condition was as common as that in adolescent women. PMID- 27702730 TI - Middle-class household food providers' views and experiences of food marketing in Vietnam. AB - BACKGROUND AND OBJECTIVES: Food marketing has been identified as a target for intervention in the prevention of childhood overweight and obesity within countries and globally, and promotion of healthy diets has been classified as a key strategy to reduce the burden of non-communicable diseases and health inequalities. The present study aims to investigate how Vietnamese middle-class household food providers are impacted by food advertising communications, their views of food marketing and the ways they think the government can control food marketing to assist people to consume healthier diets. METHODS AND STUDY DESIGN: 810 household food providers participated in the online survey. Frequency counts were calculated using IBM SPSS version 21. RESULTS: Many respondents had been exposed to food marketing; 82.8% had seen food advertising in magazines at least once a month, 65.1% had received free food samples in public places, 68.0% had received food advertising information via email. Many household food providers appeared to support food marketing; 73.3% approved of nutrition education in schools or on television being provided by soft drink or fast food companies, 63.7% supported the marketing of infant formula milk. There were mixed views about what actions the government could implement to control food marketing; 88.2% supported clearer food content on food labels, 84.1% believed that children should learn how to purchase and cook foods at school. CONCLUSIONS: A substantial majority of Vietnamese middle-class household food providers appeared unaware of the adverse effects of food marketing. Education and policy leadership in food and nutrition are urgently required. PMID- 27702731 TI - Salty food preference is associated with osteoporosis among Chinese men. AB - BACKGROUND AND OBJECTIVES: The main purpose of this study was to evaluate the associations between salty food preference and osteoporosis (OP) in general Chinese men. METHODS AND STUDY DESIGN: We conducted a largescale, community based, cross-sectional study to estimate the associations by using self-report questionnaire to evaluate the salty food preference. The total of 1,092 men was available to data analysis in this study. Multiple regression models controlling for confounding factors to include salty food preference variables were employed to explore the relationships for OP. RESULTS: We found negative correlations between preference for salty food and T-score (p=0.006). Multiple regression analysis showed that the preference for salty food was significantly positively associated with OP (p<0.05 for all). The men with preference for salty food habits had a higher prevalence of OP. CONCLUSION: The findings indicated that salty food preference was independently and significantly associated with OP. The prevalence of OP was more frequent in Chinese men preferring salty food habits. PMID- 27702732 TI - Comparison of salt taste thresholds and salt usage behaviours between adults in Myanmar and Korea. AB - BACKGROUND AND OBJECTIVES: Excessive oral salt intake can induce hypertension. According to previous studies, the prevalence of hypertension is higher in Myanmar than in Korea. We postulated that Myanmar adults had higher salt taste thresholds and eat much saltier food. This study aimed to compare salt taste thresholds and salt usage behaviour scores between adults in Myanmar and Korea. METHODS AND STUDY DESIGN: This cross-sectional study enrolled patients who visited volunteer medical service clinics at Ansung in Korea and Hlegu and Bago in Myanmar in August 2014. We measured the vital signs, heights, and weights of each patient and evaluated detection thresholds, recognition thresholds, and salt preferences. All patients underwent urinalysis and spot urine Na tests. Additionally, they each completed a salt usage behaviour questionnaire. RESULTS: A total of 131 patients were enrolled, including 64 Myanmarese patients and 67 Korean patients. Blood pressure was significantly higher in the Myanmarese than in the Koreans. Detection and recognition thresholds, salt preferences, and spot urine sodium and salt usage behaviour scores were also higher in the Myanmarese than in the Korean subjects. We calculated correlation coefficients between systolic blood pressure and parameters that were related to salt intake. The detection and recognition thresholds were significantly correlated with systolic blood pressure. CONCLUSION: All parameters related to salt intake, including detection and recognition thresholds, salt preference, salt usage behaviour scores and spot urine sodium concentrations, are significantly higher in Myanmarese than in Korean individuals. PMID- 27702733 TI - Vitamin D status of Maori and non-Maori octogenarians in New Zealand: a Cohort Study (LiLACS NZ). AB - BACKGROUND AND OBJECTIVES: This study assessed vitamin D status and its determinants in a cohort of octogenarians living within New Zealand's Bay of Plenty and Lakes Districts. METHODS AND STUDY DESIGN: Serum 25- hydroxyvitamin D [25(OH)D] concentration was measured in 209 Maori (aged 80-90 years) and 357 non Maori (85 years), along with demographic, lifestyle, supplement use and other health data. RESULTS: Mean [95% CI] 25(OH)D concentration was 69 [67 to 72] nmol/L, with 15% >100 nmol/L and 6 individuals >150 nmol/L. Concentrations in Maori (59 [55 to 62] 4 nmol/L) were lower than in non-Maori (75 [72 to 78] nmol/L; p<0.001), a difference maintained when adjusted for day-of-year measured. Vitamin D supplementation was reported by 98 participants (18%): including a greater proportion of women (24%) than men (11%; p<0.001) and of non-Maori (24%) than Maori (7%; p<0.001). Of those taking vitamin D, 49% took high oral doses (>=25 MUg/day or equivalent) and five individuals took >50 MUg/day. Vitamin D supplement use strongly and independently predicted seasonally- adjusted 25(OH)D concentration and was associated with 28 nmol/L higher levels than non-use. Other predictors included Maori ethnicity (10 nmol/L lower concentration than for non Maori), and female gender (11 nmol/L lower). CONCLUSIONS: Vitamin D status in New Zealand octogenarians appears higher than previously reported, particularly in non-Maori compared to Maori. Prescribed and non-prescribed oral vitamin D supplementation is prevalent in this group and a strong indicator of vitamin D status. PMID- 27702734 TI - The physical examination content of the Japanese National Health and Nutrition Survey: temporal changes. AB - BACKGROUND AND OBJECTIVES: Survey items of the Japan National Nutrition Survey (J NNS) have changed over time. Several papers on dietary surveys have been published; however, to date, there are no in-depth papers regarding physical examinations. Therefore, we investigated changes in the survey items in the physical examinations performed in the J-NNS and the National Health and Nutrition Survey (NHNS), with the aim of incorporating useful data for future policy decisions. METHODS AND STUDY DESIGN: We summarized the description of physical examinations and marshalled the changes of survey items from the J-NNS and NHNS from 1946 to 2012. The physical examination is roughly classified into the following six components: some are relevant to anthropometric measurements, clinical measurements, physical symptoms, blood tests, lifestyle and medication by interview, and others. RESULTS: Items related to nutritional deficiency, such as anaemia and tendon reflex disappearance, and body weight measurements were collected during the early period, according to the instructions of the General Headquarters. From 1989, blood tests and measurement of physical activity were added, and serum total protein, total cholesterol, triglycerides, HDL cholesterol, blood glucose, red blood corpuscles and haemoglobin measurements have been performed continuously for more than 20 years. CONCLUSIONS: This is the first report on the items of physical examination in the J-NNS and NHNS. Our research results provide basic information for the utilization of the J-NNS and NHNS, to researchers, clinicians or policy makers. Monitoring the current state correctly is essential for national health promotion, and also for improvement of the investigation methods to apply country-by-country comparisons. PMID- 27702735 TI - Endemic fluorosis in Henan province, China: ERalpha gene polymorphisms and reproductive hormones among women. AB - BACKGROUND AND OBJECTIVES: The aim of this study was to explore the influence of fluoride exposure and ERalpha gene polymorphisms on reproductive hormone concentrations of women in accordance with endemic fluorosis residence. METHODS AND STUDY DESIGN: A cross sectional study was conducted in Tongxu county, Henan Province, China. A total of 679 women were recruited using cluster sampling and each subject provided fasting blood and an associated urine sample. We measured the concentrations of serum gonadotropin releasing hormone (GnRH), follicle stimulating hormone, luteinizing hormone, and estradiol and urinary fluoride. RESULTS: In the defluoridation project group (DFPG), serum GnRH was lower in women carrying C/C genotype compared to in those carrying C/T and T/T genotypes of ERalpha gene rs3798577 (p<0.05). In the endemic fluorosis group (EFG), serum GnRH was lower in women carrying Pp genotype compared to in those carrying PP and pp genotypes of ERalpha PvuII (p<0.05). Serum GnRH in women from EFG who carried Pp, pp, Xx and xx genotypes in ERalpha gene PvuII and XbaI was lower than in those in the control group (CG) who carried same genotypes (p<0.05). Furthermore, serum GnRH in women from EFG was significantly lower than in those in CG, regardless of whether the women were carrying C/C, C/T or T/T genotypes of ERalpha rs3798577 (p<0.05). Serum estradiol concentrations in EFG were significantly lower than in CG when the women were carrying the Pp, Xx and T/T genotypes in ERalpha gene (p<0.05). CONCLUSION: Interaction of ERalpha gene and fluoride exposure may influence women's serum reproductive hormone concentrations. PMID- 27702737 TI - Usability Evaluation Methods for Gesture-Based Games: A Systematic Review. AB - BACKGROUND: Gestural interaction systems are increasingly being used, mainly in games, expanding the idea of entertainment and providing experiences with the purpose of promoting better physical and/or mental health. Therefore, it is necessary to establish mechanisms for evaluating the usability of these interfaces, which make gestures the basis of interaction, to achieve a balance between functionality and ease of use. OBJECTIVE: This study aims to present the results of a systematic review focused on usability evaluation methods for gesture-based games, considering devices with motion-sensing capability. We considered the usability methods used, the common interface issues, and the strategies adopted to build good gesture-based games. METHODS: The research was centered on four electronic databases: IEEE, Association for Computing Machinery (ACM), Springer, and Science Direct from September 4 to 21, 2015. Within 1427 studies evaluated, 10 matched the eligibility criteria. As a requirement, we considered studies about gesture-based games, Kinect and/or Wii as devices, and the use of a usability method to evaluate the user interface. RESULTS: In the 10 studies found, there was no standardization in the methods because they considered diverse analysis variables. Heterogeneously, authors used different instruments to evaluate gesture-based interfaces and no default approach was proposed. Questionnaires were the most used instruments (70%, 7/10), followed by interviews (30%, 3/10), and observation and video recording (20%, 2/10). Moreover, 60% (6/10) of the studies used gesture-based serious games to evaluate the performance of elderly participants in rehabilitation tasks. This highlights the need for creating an evaluation protocol for older adults to provide a user friendly interface according to the user's age and limitations. CONCLUSIONS: Through this study, we conclude this field is in need of a usability evaluation method for serious games, especially games for older adults, and that the definition of a methodology and a test protocol may offer the user more comfort, welfare, and confidence. PMID- 27702736 TI - A huge ovarian mucinous cystadenoma associated with contralateral teratoma and polycystic ovary syndrome in an obese adolescent girl. AB - A 13-year-old, obese girl presented with acute abdominal pain with abdominal distension for a year. The physical examination revealed marked abdominal distension with a large well-circumscribed mass sized 13*20 cm. Her body mass index (BMI) was 37.8 kg/m2. An abdominal CT scan revealed a huge multiloculated cystic mass and a left adnexal mass. She had an abnormal fasting plasma glucose and low HDL-C. Laparotomy, right salpingooophorectomy, left cystectomy, lymph node biopsies and partial omentectomy were performed. The left ovary demonstrated multiple cystic follicles over the cortex. The histologic diagnosis was a mucinous cystadenoma of the right ovary and a matured cystic teratoma of the left ovary. Both obesity and polycystic ovary syndrome (PCOS) are associated with a greater risk of ovarian tumours, where PCOS could be either the cause or as a consequence of an ovarian tumour. We report an obese, perimenarchal girl with bilateral ovarian tumours coexistent with a polycystic ovary and the metabolic syndrome. PMID- 27702738 TI - Health Literacy and Health Information Technology Adoption: The Potential for a New Digital Divide. AB - BACKGROUND: Approximately one-half of American adults exhibit low health literacy and thus struggle to find and use health information. Low health literacy is associated with negative outcomes including overall poorer health. Health information technology (HIT) makes health information available directly to patients through electronic tools including patient portals, wearable technology, and mobile apps. The direct availability of this information to patients, however, may be complicated by misunderstanding of HIT privacy and information sharing. OBJECTIVE: The purpose of this study was to determine whether health literacy is associated with patients' use of four types of HIT tools: fitness and nutrition apps, activity trackers, and patient portals. Additionally, we sought to explore whether health literacy is associated with patients' perceived ease of use and usefulness of these HIT tools, as well as patients' perceptions of privacy offered by HIT tools and trust in government, media, technology companies, and health care. This study is the first wide-scale investigation of these interrelated concepts. METHODS: Participants were 4974 American adults (n=2102, 42.26% male, n=3146, 63.25% white, average age 43.5, SD 16.7 years). Participants completed the Newest Vital Sign measure of health literacy and indicated their actual use of HIT tools, as well as the perceived ease of use and usefulness of these applications. Participants also answered questions regarding information privacy and institutional trust, as well as demographic items. RESULTS: Cross-tabulation analysis indicated that adequate versus less than adequate health literacy was significantly associated with use of fitness apps (P=.02), nutrition apps (P<.001), activity trackers (P<.001), and patient portals (P<.001). Additionally, greater health literacy was significantly associated with greater perceived ease of use and perceived usefulness across all HIT tools after controlling for demographics. Regarding privacy perceptions of HIT and institutional trust, patients with greater health literacy often demonstrated decreased privacy perceptions for HIT tools including fitness apps (P<.001) and nutrition apps (P<.001). Health literacy was negatively associated with trust in government (P<.001), media (P<.001), and technology companies (P<.001). Interestingly, health literacy score was positively associated with trust in health care (P=.03). CONCLUSIONS: Patients with low health literacy were less likely to use HIT tools or perceive them as easy or useful, but they perceived information on HIT as private. Given the fast-paced evolution of technology, there is a pressing need to further the understanding of how health literacy is related to HIT app adoption and usage. This will ensure that all users receive the full health benefits from these technological advances, in a manner that protects health information privacy, and that users engage with organizations and providers they trust.

PMID- 27702740 TI - Neuro-cognitive mechanisms of simultanagnosia in patients with posterior cortical atrophy. AB - Posterior cortical atrophy is dominated by progressive degradation of parieto occipital grey and white matter, and represents in most cases a variant of Alzheimer's disease. Patients with posterior cortical atrophy are characterized by increasing higher visual and visuo-spatial impairments. In particular, a key symptom of posterior cortical atrophy is simultanagnosia i.e. the inability to perceive multiple visual objects at the same time. Two neuro-cognitive mechanisms have been suggested to underlie simultanagnosia, either reduced visual short-term memory capacity or decreased visual processing speed possibly resulting from white matter impairments over and above damage to cortical brain areas. To test these distinct hypotheses, we investigated a group of 12 patients suffering from posterior cortical atrophy with homogenous lesion sides in parieto-occipital cortices and varying severity of grey and white matter loss. More specifically, we (i) tested whether impaired short-term memory capacity or processing speed underlie symptoms of simultanagnosia; (ii) assessed the link to grey and white matter damage; and (iii) integrated those findings into a neuro-cognitive model of simultanagnosia in patients with posterior cortical atrophy. To this end, simultaneous perception of multiple visual objects was tested in patients with posterior cortical atrophy mostly with positive Alzheimer's disease biomarkers and healthy age-matched controls. Critical outcome measures were identification of overlapping relative to non-overlapping figures and visuo-spatial performance in tests sensitive to simultanagnosia. Using whole report of briefly presented letter arrays based on the mathematically formulated 'Theory of Visual Attention', we furthermore quantified parameters of visual short-term memory capacity and visual processing speed. Grey and white matter atrophy was assessed by voxel-based morphometry analyses of structural magnetic resonance data. All patients showed severe deficits of simultaneous perception. Compared to controls, we observed a specific slowing of visual processing speed, while visual short term memory capacity was preserved. In a regression analysis, processing speed was identified as the only significant predictor of simultaneous perception deficits that explained a high degree of variance (70-82%) across simultanagnosia tasks. More severe slowing was also indicative for more severe impairments in reading and scene comprehension. Voxel-based morphometry yielded extensive reductions of grey and white matter in parieto-occipital and thalamic brain areas. Importantly, the degree of individual atrophy of white matter in left superior parietal lobe, but not of any grey matter region, was associated with processing speed. Based on these findings, we propose that atrophy of white matter commonly observed in posterior cortical atrophy leads to slowing of visual processing speed, which underlies the overt clinical symptoms of simultanagnosia.

PMID- 27702747 TI - Prolonged sitting negatively affects the postprandial plasma triglyceride lowering effect of acute exercise. AB - The interaction of prolonged sitting with physical exercise for maintaining health is unclear. We tested the hypothesis that prolonged siting would have a deleterious effect on postprandial plasma lipemia (PPL, postprandial plasma triglycerides) and reduce the ability of an acute exercise bout to attenuate PPL. Seven healthy young men performed three, 5-day interventions [days 1-5 (D1-D5)] in a randomized crossover design with >1 wk between interventions: 1) sitting > 14 h/day with hypercaloric energy balance (SH), 2) sitting >14 h/day with net energy balance (SB), and 3) active walking/standing with net energy balance (WB) and sitting 8.4 h/day. The first high-fat tolerance test (HFTT1) was performed on D3 following 2 days of respective interventions. On the evening of D4 subjects ran on a treadmill for 1 h at ~67% Vo2max, followed by the second HFTT (HFTT2) on D5. Two days of prolonged sitting increased TG AUCI (i.e., incremental area under the curve for TG), irrespective of energy balance, compared with WB (27% in SH, P = 0.003 and 26% in SB, P = 0.046). Surprisingly, after 4 days of prolonged sitting (i.e.; SH and SB), the acute exercise on D4 failed to attenuate TG AUCI or increase relative fat oxidation in HFTT2, compared with HFTT1, regardless of energy balance. In conclusion, prolonged sitting over 2-4 days was sufficient to amplify PPL, which was not attenuated by acute exercise, regardless of energy balance. This underscores the importance of limiting sitting time even in people who have exercised. PMID- 27702748 TI - Healthcare professionals must lead on climate change. PMID- 27702745 TI - Estimation of Inorganic Arsenic Exposure in Populations With Frequent Seafood Intake: Evidence From MESA and NHANES. AB - The sum of urinary inorganic arsenic (iAs) and methylated arsenic (monomethylarsonate and dimethylarsinate (DMA)) species is the main biomarker of iAs exposure. Assessing iAs exposure, however, is difficult in populations with moderate-to-high seafood intakes. In the present study, we used subsamples from the Multi-Ethnic Study of Atherosclerosis (2000-2002) (n = 310) and the 2003-2006 National Health and Nutrition Examination Survey (n = 1,175). We calibrated urinary concentrations of non-seafood-derived iAs, DMA, and methylarsonate, as well as the sum of inorganic and methylated arsenic species, in the Multi-Ethnic Study of Atherosclerosis and of DMA in the National Health and Nutrition Examination Survey by regressing their original concentrations by arsenobetaine and extracting model residuals. To confirm that calibrated biomarkers reflected iAs exposure but not seafood intake, we compared urinary arsenic concentrations by levels of seafood and rice intakes. Self-reported seafood intakes, estimated n 3 polyunsaturated fatty acid levels, and measured n-3 polyunsaturated fatty acid levels were positively associated with the original urinary arsenic biomarkers. Using the calibrated arsenic biomarkers, we found a marked attenuation of the associations with self-reported seafood intake and estimated or measured n-3 fatty acids, whereas associations with self-reported rice intake remained similar. Our residual-based method provides estimates of iAs exposure and metabolism for each participant that no longer reflect seafood intake and can facilitate research about low-to-moderate levels of iAs exposure in populations with high seafood intakes. PMID- 27702746 TI - Caspase-1 deficiency promotes high-fat diet-induced adipose tissue inflammation and the development of obesity. AB - Caspase-1 is a cysteine protease responsible for the processing of the proinflammatory cytokine interleukin-1beta and activated by the formation of inflammasome complexes. Although several investigations have found a link between diet-induced obesity and caspase-1, the relationship remains controversial. Here, we found that mice deficient in caspase-1 were susceptible to high-fat diet induced obesity with increased adiposity as well as normal lipid and glucose metabolism. Caspase-1 deficiency clearly promoted the infiltration of inflammatory macrophages and increased the production of C-C motif chemokine ligand 2 (CCL2) in the adipose tissue. The dominant cellular source of CCL2 was stromal vascular fraction rather than adipocytes in the adipose tissue. These findings demonstrate a critical role of caspase-1 in macrophage-driven inflammation in the adipose tissue and the development of obesity. These data provide novel insights into the mechanisms underlying inflammation in the pathophysiology of obesity. PMID- 27702749 TI - Toll-Like Receptors, Hypertension, and an Antimalarial Drug.

AB - Genomic sequence diversity of a bacterial species mainly results from the frequency distribution of single nucleotide polymorphisms (SNPs). Here we report on a SNP-matrix based binary algorithm to determine the intra- or interclonal genomic diversity by the number of shared sequential SNPs, the so-called SNP synteny or haplotype. All SNP positions and the frequency and length distribution of haplotypes are determined from pairwise alignment of completely sequenced genomes. This metric is invariant regarding the reference genome chosen. Information is obtained about the size of haplotypes, genomic gradients of recombination frequency, relatedness of strains and population composition of a taxon or clonal populations. The approach is illustrated with whole genome data sets of Staphylococcus aureus and Pseudomonas aeruginosa strains. PMID- 27702753 TI - Fractionation of sulfur and hydrogen isotopes in Desulfovibrio vulgaris with perturbed DsrC expression. AB - Dissimilatory sulfate reduction is the central microbial metabolism in global sulfur cycling. Understanding the importance of sulfate reduction to Earth's biogeochemical S cycle requires aggregating single-cell processes with geochemical signals. For sulfate reduction, these signals include the ratio of stable sulfur isotopes preserved in minerals, as well as the hydrogen isotope ratios and structures of microbial membrane lipids preserved in organic matter. In this study, we cultivated the model sulfate reducer, Desulfovibrio vulgaris DSM 644T, to investigate how these parameters were perturbed by changes in expression of the protein DsrC. DsrC is critical to the final metabolic step in sulfate reduction to sulfide. S and H isotopic fractionation imposed by the wild type was compared to three mutants. Discrimination against 34S in sulfate, as calculated from the residual reactant, did not discernibly differ among all strains. However, a closed-system sulfur isotope distillation model, based on accumulated sulfide, produced inconsistent results in one mutant strain IPFG09. Lipids produced by IPFG09 were also slightly enriched in 2H. These results suggest that DsrC alone does not have a major impact on sulfate-S, though may influence sulfide-S and lipid-H isotopic compositions. While intriguing, a mechanistic explanation requires further study under continuous culture conditions. PMID- 27702751 TI - Patient-derived tumour xenografts for breast cancer drug discovery. AB - Despite remarkable advances in our understanding of the drivers of human malignancies, new targeted therapies often fail to show sufficient efficacy in clinical trials. Indeed, the cost of bringing a new agent to market has risen substantially in the last several decades, in part fuelled by extensive reliance on preclinical models that fail to accurately reflect tumour heterogeneity. To halt unsustainable rates of attrition in the drug discovery process, we must develop a new generation of preclinical models capable of reflecting the heterogeneity of varying degrees of complexity found in human cancers. Patient derived tumour xenograft (PDTX) models prevail as arguably the most powerful in this regard because they capture cancer's heterogeneous nature. Herein, we review current breast cancer models and their use in the drug discovery process, before discussing best practices for developing a highly annotated cohort of PDTX models. We describe the importance of extensive multidimensional molecular and functional characterisation of models and combination drug-drug screens to identify complex biomarkers of drug resistance and response. We reflect on our own experiences and propose the use of a cost-effective intermediate pharmacogenomic platform (the PDTX-PDTC platform) for breast cancer drug and biomarker discovery. We discuss the limitations and unanswered questions of PDTX models; yet, still strongly envision that their use in basic and translational research will dramatically change our understanding of breast cancer biology and how to more effectively treat it.

PMID- 27702752 TI - Emerging data on androgen receptor splice variants in prostate cancer. AB - Androgen receptor splice variants are alternatively spliced variants of androgen receptor, which are C-terminally truncated and lack the canonical ligand-binding domain. Accumulating evidence has indicated a significant role of androgen receptor splice variants in mediating resistance of castration-resistant prostate cancer to current therapies and in predicting therapeutic responses. As such, there is an urgent need to target androgen receptor splicing variants for more effective treatment of castration-resistant prostate cancer. Identification of precise and critical targeting points to deactivate androgen receptor splicing variants relies on a deep understanding of how they are generated and the mechanisms of their action. In this review, we will focus on the emerging data on their generation, clinical significance and mechanisms of action as well as the therapeutic influence of these findings.

PMID- 27702760 TI - Bidirectional regulation of fragile X mental retardation protein phosphorylation controls rhodopsin homoeostasis. AB - Homoeostatic regulation of the light sensor, rhodopsin, is critical for the maintenance of light sensitivity and survival of photoreceptors. The major fly rhodopsin, Rh1, undergoes light-induced endocytosis and degradation, but its protein and mRNA levels remain constant during light/dark cycles. It is not clear how translation of Rh1 is regulated. Here, we show that adult photoreceptors maintain a constant, abundant quantity of ninaE mRNA, which encodes Rh1. We demonstrate that the Fmr1 protein associates with ninaE mRNA and represses its translation. Further, light exposure triggers a calcium-dependent dephosphorylation of Fmr1, which relieves suppression of Rh1 translation. We demonstrate that Mts, the catalytic subunit of protein phosphatase 2A (PP2A), mediates light-induced Fmr1 dephosphorylation in a regulatory B subunit of PP2A (CKa)-dependent manner. Finally, we show that blocking light-induced Rh1 translation results in reduced light sensitivity. Our results reveal the molecular mechanism of Rh1 homoeostasis and physiological consequence of Rh1 dysregulation. PMID- 27702761 TI - SENP1 regulates IFN-gamma-STAT1 signaling through STAT3-SOCS3 negative feedback loop. AB - Interferon-gamma (IFN-gamma) triggers macrophage for inflammation response by activating the intracellular JAK-STAT1 signaling. Suppressor of cytokine signaling 1 (SOCS1) and protein tyrosine phosphatases can negatively modulate IFN gamma signaling. Here, we identify a novel negative feedback loop mediated by STAT3-SOCS3, which is tightly controlled by SENP1 via de-SUMOylation of protein tyrosine phosphatase 1B (PTP1B), in IFN-gamma signaling. SENP1-deficient macrophages show defects in IFN-gamma signaling and M1 macrophage activation. PTP1B in SENP1-deficient macrophages is highly SUMOylated, which reduces PTP1B induced de-phosphorylation of STAT3. Activated STAT3 then suppresses STAT1 activation via SOCS3 induction in SENP1-deficient macrophages. Accordingly, SENP1 deficient macrophages show reduced ability to resist Listeria monocytogenes infection. These results reveal a crucial role of SENP1-controlled STAT1 and STAT3 balance in macrophage polarization.

METHODS AND RESULTS: We investigated the effect of subcutaneous injection of exenatide or local delivery of a recombinant adenovirus expressing GLP-1 (rAd-GLP-1) into carotid artery, in reducing the occurrence of restenosis following balloon injury. As a control, we inserted beta-galactosidase cDNA in the same vector (rAd-betaGAL). Otsuka Long-Evans Tokushima rats were assigned to three groups (n = 12 each): (1) normal saline plus rAd-betaGAL delivery (NS + rAd betaGAL), (2) exenatide plus rAd-betaGAL delivery (Exenatide + rAd-betaGAL), and (3) normal saline plus rAd-GLP-1 delivery (NS + rAd-GLP-1). Normal saline or exenatide were administered subcutaneously from 1 week before to 2 weeks after carotid injury. After 3 weeks, the NS + rAd-betaGAL group showed the highest intima-media ratio (IMR; 3.73 +/- 0.90), the exenatide + rAd-betaGAL treatment was the next highest (2.80 +/- 0.51), and NS + rAd-GLP-1 treatment showed the lowest IMR (1.58 +/- 0.48, P < 0.05 vs. others). The proliferation and migration of vascular smooth muscle cells and monocyte adhesion were decreased significantly after rAd-GLP-1 treatment, showing the same overall patterns as the IMR. In injured vessels, the apoptosis was greater and MMP2 expression was less in the NS + rAd-GLP-1 than in the exenatide or rAd-betaGAL groups. In vitro expressions of matrix metalloproteinases-2 and monocyte chemoattractant protein-1 and nuclear factor-kappa-B-p65 translocation were decreased more in the NS + rAd GLP-1 group than in the other two groups (all P < 0.05). CONCLUSION: Direct GLP-1 overexpression showed better protection against restenosis after balloon injury via suppression of vascular smooth muscle cell migration, increased apoptosis, and decreased inflammatory processes than systemic exenatide treatment. This has potential therapeutic implications for treating macrovascular complications in diabetes. PMID- 27702764 TI - Analysis of bacterial composition in marine sponges reveals the influence of host phylogeny and environment. AB - Bacterial communities associated with sponges are influenced by environmental factors; however, some degree of genetic influence of the host on the microbiome is also expected. In this work, 16S rRNA gene amplicon sequencing revealed diverse bacterial phylotypes based on the phylogenies of three tropical sponges (Aplysina fulva, Aiolochroia crassa and Chondrosia collectrix). Despite their sympatric occurrence, the studied sponges presented different bacterial compositions that differed from those observed in seawater. However, lower dissimilarities in bacterial communities were observed within sponges from the same phylogenetic group. The relationships between operational taxonomic units (OTUs) recovered from the sponges and database sequences revealed associations among sequences from unrelated sponge species and sequences retrieved from diverse environmental samples. In addition, one Proteobacteria OTU retrieved from A. fulva was identical to sequences previously reported from A. fulva specimens collected along the Brazilian coast. Based on these results, we conclude that bacterial communities associated with marine sponges are shaped by host identity, while environmental conditions seem to be less important in shaping symbiont communities. This is the first study to assess bacterial communities associated with marine sponges in the remote St. Peter and St. Paul Archipelago using amplicon sequencing of the 16S rRNA gene. PMID- 27702765 TI - Phylogeographic analyses of bacterial endosymbionts in fig homotomids (Hemiptera: Psylloidea) reveal codiversification of both primary and secondary endosymbionts. AB - While obligate primary (P-) endosymbionts usually cospeciate with their insect hosts, less is known about codiversification of secondary (S-) endosymbionts that are generally considered facultative. Typically, insects of the superfamily Psylloidea harbour one P- (Carsonella) and at least one S-endosymbiont, thought to compensate for Carsonella genome reduction. Most codiversification studies have used phylogenies of psyllids and their endosymbionts across and within host families or genera, but few have explored patterns within species. We focussed on P- and S-endosymbionts of three Mycopsylla (Homotomidae) species to explore whether they have congruent phylogenies and within-species geographic structures. The P-endosymbiont Carsonella, a S-endosymbiont and Wolbachia all had 100% prevalence, while Arsenophonus was only found in one species at low prevalence. Congruent phylogenies of Mycopsylla and P-endosymbionts across populations and species support strict cospeciation. S-endosymbiont phylogenies were also congruent across host species but low genetic variation in the S-endosymbiont was not correlated with host phylogeography, possibly due to a shorter evolutionary association. Between species, Wolbachia and Mycopsylla phylogenies were incongruent, probably due to horizontal transmission events. Our study is the first to explore endosymbionts of Mycopsylla and further supports the codivergence of Psylloidea hosts and P-endosymbionts, with obligate host interactions for both P- and S-endosymbionts. PMID- 27702766 TI - Five-Year Optical Coherence Tomography in Patients With ST-Segment-Elevation Myocardial Infarction Treated With Bare-Metal Versus Everolimus-Eluting Stents. AB - BACKGROUND: The main causes of late (>1 month) stent thrombosis (ST) are stent uncoverage, malapposition, and neoatherosclerosis. First-generation drug-eluting stents were associated with higher rate of late ST compared with bare-metal stents (BMS), especially in patients with ST-segment-elevation myocardial infarction. Second-generation everolimus-eluting stents (EES) have shown similar rate of late ST than BMS. The aims of the study are to compare the ratio of uncovered to total struts per cross-section >=30% and other optical coherence tomographic findings associated with ST between EES and BMS in patients with ST segment-elevation myocardial infarction at 5 years. METHODS AND RESULTS: One hundred and sixty-nine consecutive event-free patients of the randomized EXAMINATION study (A Clinical Evaluation of Everolimus Eluting Coronary Stents in the Treatment of Patients With ST-Segment Elevation Myocardial Infarction) were screened for optical coherence tomographic imaging at 5 years. Patients with target vessel-related events or life-threatening comorbidities were excluded. Finally, 64 patients (32 EES and 32 BMS) underwent optical coherence tomographic imaging. At 5 years, uncovered struts (4.1% versus 1.0%; P<0.01), length of uncoverage (3.4 versus 1.4 mm; P=0.02), and ratio of uncovered to total struts per cross-section >=30% (35.5% versus 9.7%; P=0.02) were larger with EES than that with BMS. Malapposed struts (1.2% versus 0.3%; P=0.02) and malapposition length (1.3 versus 0.4 mm; P=0.06) were also larger with EES. Neoatherosclerotic plaques (16.1% versus 25.8%; P=0.35) and macrophage accumulations (19.4% versus 48.4%; P=0.02) were numerically more frequent with BMS. CONCLUSIONS: Despite substantial dropout of patients, the healing pattern in event-free ST-segment elevation myocardial infarction patients differs between EES and BMS at 5 years. EES presented with larger amount of uncovered and malapposed struts and similar rate of neoatherosclerosis as compared with BMS. The clinical relevance of these findings warrants longer follow-up.

PMID- 27702763 TI - Glucagon-like peptide-1 (GLP-1) mediates cardioprotection by remote ischaemic conditioning. AB - AIMS: Although the nature of the humoral factor which mediates cardioprotection established by remote ischaemic conditioning (RIc) remains unknown, parasympathetic (vagal) mechanisms appear to play a critical role. As the production and release of many gut hormones is modulated by the vagus nerve, here we tested the hypothesis that RIc cardioprotection is mediated by the actions of glucagon-like peptide-1 (GLP-1). METHODS AND RESULTS: A rat model of myocardial infarction (coronary artery occlusion followed by reperfusion) was used. Remote ischaemic pre- (RIPre) or perconditioning (RIPer) was induced by 15 min occlusion of femoral arteries applied prior to or during the myocardial ischaemia. The degree of RIPre and RIPer cardioprotection was determined in conditions of cervical or subdiaphragmatic vagotomy, or following blockade of GLP-1 receptors (GLP-1R) using specific antagonist Exendin(9-39). Phosphorylation of PI3K/AKT and STAT3 was assessed. RIPre and RIPer reduced infarct size by ~50%. In conditions of bilateral cervical or subdiaphragmatic vagotomy RIPer failed to establish cardioprotection. GLP-1R blockade abolished cardioprotection induced by either RIPre or RIPer. Exendin(9-39) also prevented RIPre-induced AKT phosphorylation. Cardioprotection induced by GLP-1R agonist Exendin-4 was preserved following cervical vagotomy, but was abolished in conditions of M3 muscarinic receptor blockade. CONCLUSIONS: These data strongly suggest that GLP-1 functions as a humoral factor of remote ischaemic conditioning cardioprotection. This phenomenon requires intact vagal innervation of the visceral organs and recruitment of GLP 1R-mediated signalling. Cardioprotection induced by GLP-1R activation is mediated by a mechanism involving M3 muscarinic receptors.

PMID- 27702769 TI - Hyperactivation of mammalian target of rapamycin complex 1 by HIV-1 is necessary for virion production and latent viral reactivation. AB - Generation of new HIV-1 virions requires the constant supply of proteins, nucleotides, and energy; however, it is not known which cellular pathways are perturbed and what molecular mechanisms are employed. We hypothesized that HIV-1 may regulate pathways that control synthesis of biomolecules in the cell. In this study, we provide evidence that HIV-1 hyperactivates mammalian target of rapamycin complex 1 (mTORC1), the central regulator of biosynthesis. Mechanistically, we identify the viral regulatory gene tat (transactivator) as being responsible for increasing mTORC1 activity in a PI3K-dependent manner. Furthermore, we show that hyperactivation of mTORC1 leads to activation of the enzyme, carbamoyl-phosphate synthetase 2, aspartate transcarbamylase, dihydroorotase, and repression of initiation factor 4E-binding protein 1 activity. These are regulators of nucleotide biogenesis and protein translation, respectively. Moreover, we are able to replicate these results in HIV-1 latent cell line models. Finally, we show that inhibition of mTORC1 or PI3K inhibits viral replication and viral reactivation as a result of a decrease in biosynthesis. Overall, our study identifies a new avenue in HIV-1 biology that can lead to development of novel therapeutic targets.-Kumar, B., Arora, S., Ahmed, S., Banerjea, A. C.

AB - BACKGROUND: Circulating A/H3N2 influenza viruses drifted significantly after strain selection for the 2014-2015 vaccines. Also in 2014-2015, the Advisory Committee on Immunization Practices recommended preferential use of live attenuated influenza vaccine (LAIV) over inactivated influenza vaccine (IIV) among children aged 2-8 years. METHODS: Vaccine effectiveness (VE) across age groups and vaccine types was examined among outpatients with acute respiratory illness at 5 US sites using a test-negative design, that compared the odds of vaccination among reverse transcription polymerase chain reaction-confirmed influenza positives and negatives. RESULTS: Of 9311 enrollees with complete data, 7078 (76%) were influenza negative, 1840 (19.8%) were positive for influenza A (A/H3N2, n = 1817), and 395 (4.2%) were positive for influenza B (B/Yamagata, n = 340). The overall adjusted VE was 19% (95% confidence interval [CI], 10% to 27%) and was statistically significant in all age strata except those aged 18-64 years. The adjusted VE of 6% (95%CI, -5% to 17%) against A/H3N2 associated illness was not statistically significant, unlike VE for influenza B/Yamagata, which was 55% (95%CI, 43% to 65%). Among those aged 2-8 years, VE against A/H3N2 was 15% (95%CI, -16% to 38%) for IIV and -3% (CI, -50% to 29%) for LAIV; VE against B/Yamagata was 40% (95%CI, -20% to 70%) for IIV and 74% (95%CI, 25% to 91%) for LAIV. CONCLUSIONS: The 2014-2015 influenza vaccines offered little protection against the predominant influenza A/H3N2 virus but were effective against influenza B. Preferential use of LAIV among young children was not supported. PMID- 27702770 TI - Impaired sensitivity to pain stimuli in plasma membrane calcium ATPase 2 (PMCA2) heterozygous mice: a possible modality- and sex-specific role for PMCA2 in nociception. AB - Plasma membrane calcium ATPase 2 (PMCA2) is a calcium pump that plays important roles in neuronal function. Although it is expressed in pain-associated regions of the CNS, including in the dorsal horn (DH), its contribution to pain remains undefined. The present study assessed the role of PMCA2 in pain responsiveness and the link between PMCA2 and glutamate receptors, GABA receptors (GABARs), and glutamate transporters that have been implicated in pain processing in the DH of adult female and male PMCA2+/+ and PMCA2+/- mice. Behavioral assays evaluated mechanical and thermal pain responsiveness. Mechanical sensitivity was significantly increased by 52% and heat sensitivity was reduced by 29% in female, but not male, PMCA2+/- mice compared with PMCA2+/+ controls. There were female specific changes in metabotropic glutamate receptor 1, NMDA receptor 2A, alpha amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor subunit GluR1, GABABR1, and GABABR2 levels, whereas metabotropic glutamate receptor 5, NMDA receptor 2B, GluR2, and GABAARalpha2 levels were not altered. Glutamate aspartate transporter levels were higher and glial glutamate transporter 1 levels were lower in the DH of female, but not male, PMCA2+/- mice. These findings indicate a novel role for PMCA2 in modality- and sex-dependent pain responsiveness. Female specific molecular changes potentially account for the altered pain responses.

PMID- 27702772 TI - The Nucleolar Fibrillarin Protein Is Required for Helper Virus-Independent Long Distance Trafficking of a Subviral Satellite RNA in Plants. AB - RNA trafficking plays pivotal roles in regulating plant development, gene silencing, and adaptation to environmental stress. Satellite RNAs (satRNAs), parasites of viruses, depend on their helper viruses (HVs) for replication, encapsidation, and efficient spread. However, it remains largely unknown how satRNAs interact with viruses and the cellular machinery to undergo trafficking. Here, we show that the P20 protein of Bamboo mosaic potexvirus satRNA (satBaMV) can functionally complement in trans the systemic trafficking of P20-defective satBaMV in infected Nicotiana benthamiana The transgene-derived satBaMV, uncoupled from HV replication, was able to move autonomously across a graft union identified by RT-qPCR, RNA gel blot, and in situ RT-PCR analyses. Coimmunoprecipitation experiments revealed that the major nucleolar protein fibrillarin is coprecipitated in the P20 protein complex. Notably, silencing fibrillarin suppressed satBaMV-, but not HV-, phloem-based movement following grafting or coinoculation with HV Confocal microscopy revealed that the P20 protein colocalized with fibrillarin in the nucleoli and formed punctate structures associated with plasmodesmata. The mobile satBaMV RNA appears to exist as ribonucleoprotein (RNP) complex composed of P20 and fibrillarin, whereas BaMV movement proteins, capsid protein, and BaMV RNA are recruited with HV coinfection. Taken together, our findings provide insight into movement of satBaMV via the fibrillarin-satBaMV-P20 RNP complex in phloem-mediated systemic trafficking. PMID- 27702774 TI - Rapid Functional and Sequence Differentiation of a Tandemly Repeated Species Specific Multigene Family in Drosophila. AB - Gene clusters of recently duplicated genes are hotbeds for evolutionary change. However, our understanding of how mutational mechanisms and evolutionary forces shape the structural and functional evolution of these clusters is hindered by the high sequence identity among the copies, which typically results in their inaccurate representation in genome assemblies. The presumed testis-specific, chimeric gene Sdic originated, and tandemly expanded in Drosophila melanogaster, contributing to increased male-male competition. Using various types of massively parallel sequencing data, we studied the organization, sequence evolution, and functional attributes of the different Sdic copies. By leveraging long-read sequencing data, we uncovered both copy number and order differences from the currently accepted annotation for the Sdic region. Despite evidence for pervasive gene conversion affecting the Sdic copies, we also detected signatures of two episodes of diversifying selection, which have contributed to the evolution of a variety of C-termini and miRNA binding site compositions. Expression analyses involving RNA-seq datasets from 59 different biological conditions revealed distinctive expression breadths among the copies, with three copies being transcribed in females, opening the possibility to a sexually antagonistic effect. Phenotypic assays using Sdic knock-out strains indicated that should this antagonistic effect exist, it does not compromise female fertility. Our results strongly suggest that the genome consolidation of the Sdic gene cluster is more the result of a quick exploration of different paths of molecular tinkering by different copies than a mere dosage increase, which could be a recurrent evolutionary outcome in the presence of persistent sexual selection. PMID- 27702775 TI - SLiM 2: Flexible, Interactive Forward Genetic Simulations. AB - Modern population genomic datasets hold immense promise for revealing the evolutionary processes operating in natural populations, but a crucial prerequisite for this goal is the ability to model realistic evolutionary scenarios and predict their expected patterns in genomic data. To that end, we present SLiM 2: an evolutionary simulation framework that combines a powerful, fast engine for forward population genetic simulations with the capability of modeling a wide variety of complex evolutionary scenarios. SLiM achieves this flexibility through scriptability, which provides control over most aspects of the simulated evolutionary scenarios with a simple R-like scripting language called Eidos. An example SLiM simulation is presented to illustrate the power of this approach. SLiM 2 also includes a graphical user interface for simulation construction, interactive runtime control, and dynamic visualization of simulation output, facilitating easy and fast model development with quick prototyping and visual debugging. We conclude with a performance comparison between SLiM and two other popular forward genetic simulation packages. PMID- 27702773 TI - Clinical Outcomes in 3343 Children and Adults With Rheumatic Heart Disease From 14 Low- and Middle-Income Countries: Two-Year Follow-Up of the Global Rheumatic Heart Disease Registry (the REMEDY Study). AB - BACKGROUND: There are few contemporary data on the mortality and morbidity associated with rheumatic heart disease or information on their predictors. We report the 2-year follow-up of individuals with rheumatic heart disease from 14 low- and middle-income countries in Africa and Asia. METHODS: Between January 2010 and November 2012, we enrolled 3343 patients from 25 centers in 14 countries and followed them for 2 years to assess mortality, congestive heart failure, stroke or transient ischemic attack, recurrent acute rheumatic fever, and infective endocarditis. RESULTS: Vital status at 24 months was known for 2960 (88.5%) patients. Two-thirds were female. Although patients were young (median age, 28 years; interquartile range, 18-40), the 2-year case fatality rate was high (500 deaths, 16.9%). Mortality rate was 116.3/1000 patient-years in the first year and 65.4/1000 patient-years in the second year. Median age at death was 28.7 years. Independent predictors of death were severe valve disease (hazard ratio [HR], 2.36; 95% confidence interval [CI], 1.80-3.11), congestive heart failure (HR, 2.16; 95% CI, 1.70-2.72), New York Heart Association functional class III/IV (HR, 1.67; 95% CI, 1.32-2.10), atrial fibrillation (HR, 1.40; 95% CI, 1.10-1.78), and older age (HR, 1.02; 95% CI, 1.01-1.02 per year increase) at enrollment. Postprimary education (HR, 0.67; 95% CI, 0.54-0.85) and female sex (HR, 0.65; 95% CI, 0.52-0.80) were associated with lower risk of death. Two hundred and four (6.9%) patients had new congestive heart failure (incidence, 38.42/1000 patient-years), 46 (1.6%) had a stroke or transient ischemic attack (8.45/1000 patient-years), 19 (0.6%) had recurrent acute rheumatic fever (3.49/1000 patient-years), and 20 (0.7%) had infective endocarditis (3.65/1000 patient-years). Previous stroke and older age were independent predictors of stroke/transient ischemic attack or systemic embolism. Patients from low- and lower-middle-income countries had significantly higher age- and sex-adjusted mortality than patients from upper-middle-income countries. Valve surgery was significantly more common in upper-middle-income than in lower-middle- or low income countries. CONCLUSIONS: Patients with clinical rheumatic heart disease have high mortality and morbidity despite being young; those from low- and lower middle-income countries had a poorer prognosis associated with advanced disease and low education. Programs focused on early detection and the treatment of clinical rheumatic heart disease are required to improve outcomes. PMID- 27702776 TI - Reconstruction of Haplotype-Blocks Selected during Experimental Evolution. AB - The genetic analysis of experimentally evolving populations typically relies on short reads from pooled individuals (Pool-Seq). While this method provides reliable allele frequency estimates, the underlying haplotype structure remains poorly characterized. With small population sizes and adaptive variants that start from low frequencies, the interpretation of selection signatures in most Evolve and Resequencing studies remains challenging. To facilitate the characterization of selection targets, we propose a new approach that reconstructs selected haplotypes from replicated time series, using Pool-Seq data. We identify selected haplotypes through the correlated frequencies of alleles carried by them. Computer simulations indicate that selected haplotype blocks of several Mb can be reconstructed with high confidence and low error rates, even when allele frequencies change only by 20% across three replicates. Applying this method to real data from D. melanogaster populations adapting to a hot environment, we identify a selected haplotype-block of 6.93 Mb. We confirm the presence of this haplotype-block in evolved populations by experimental haplotyping, demonstrating the power and accuracy of our haplotype reconstruction from Pool-Seq data. We propose that the combination of allele frequency estimates with haplotype information will provide the key to understanding the dynamics of adaptive alleles. PMID- 27702778 TI - A study on a dental device for the prevention of mucosal dose enhancement caused by backscatter radiation from dental alloy during external beam radiotherapy. AB - The changes in dose distribution caused by backscatter radiation from a common commercial dental alloy (Au-Ag-Pd dental alloy; DA) were investigated to identify the optimal material and thicknesses of a dental device (DD) for effective prevention of mucositis. To this end, 1 cm3 of DA was irradiated with a 6-MV X ray beam (100 MU) in a field size of 10 * 10 cm2 using a Novalis TX linear accelerator. Ethylene vinyl acetate copolymer, polyolefin elastomer, and polyethylene terephthalate (PET) were selected as DD materials. The depth dose along the central axis was determined with respect to the presence/absence of DA and DDs at thicknesses of 1-10 mm using a parallel-plate ionization chamber. The dose in the absence of DDs showed the lowest value at a distance of 5 mm from the DA surface and gradually increased with distance between the measurement point and the DA surface for distances of >=5 mm. Except for PET, no significant difference between the DA dose curves for the presence and absence of DDs was observed. In the dose curve, PET showed a slightly higher dose for DA with DD than for DA without DD for thicknesses of >=4 mm. The findings herein suggest that the optimal DD material for preventing local dose enhancement of the mucosa caused by DA backscatter radiation should have a relatively low atomic number and physical density and that optimal DD thickness should be chosen considering backscatter radiation and percentage depth dose. PMID- 27702779 TI - Pattern of recovery after open reduction and internal fixation of proximal phalangeal fractures in the finger: a prospective longitudinal study. AB - : The purpose of this study was to determine the pattern of recovery after open reduction and internal fixation of proximal phalangeal fractures. A prospective longitudinal study of 66 patients who started rehabilitation within 1 week of fixation was undertaken. Measures of the level of impairment (range of motion, pain, strength), activity limitation (hand use) and return to work were collected at Weeks 1, 6, 12 and 26 after operation. Before starting rehabilitation, although pain was minimal, the range of motion was severely restricted and there was considerable restriction in ability to work. Most of the recovery in range of motion, pain, strength, hand use and work participation occurred by Week 6, with smaller gains by Week 12 and Week 26. LEVEL OF EVIDENCE: III. PMID- 27702777 TI - Loss and Gain of Human Acidic Mammalian Chitinase Activity by Nonsynonymous SNPs. AB - Acidic mammalian chitinase (AMCase) is implicated in asthma, allergic inflammation, and food processing. Little is known about genetic and evolutional regulation of chitinolytic activity of AMCase. Here, we relate human AMCase polymorphisms to the mouse AMCase, and show that the highly active variants encoded by nonsynonymous single-nucleotide polymorphisms (nsSNPs) are consistent with the mouse AMCase sequence. The chitinolytic activity of the recombinant human AMCase was significantly lower than that of the mouse counterpart. By creating mouse-human chimeric AMCase protein we found that the presence of the N terminal region of human AMCase containing conserved active site residues reduced the enzymatic activity of the molecule. We were able to significantly increase the activity of human AMCase by amino acid substitutions encoded by nsSNPs (N45, D47, and R61) with those conserved in the mouse homologue (D45, N47, and M61). For abolition of the mouse AMCase activity, introduction of M61R mutation was sufficient. M61 is conserved in most of primates other than human and orangutan as well as in other mammals. Orangutan has I61 substitution, which also markedly reduced the activity of the mouse AMCase, indicating that the M61 is a crucial residue for the chitinolytic activity. Altogether, our data suggest that human AMCase has lost its chitinolytic activity by integration of nsSNPs during evolution and that the enzyme can be reactivated by introducing amino acids conserved in the mouse counterpart.

AB - In June 2016, around 200 scientists from all over the world gathered at EMBL headquarters in Heidelberg, Germany to discuss the recent advances in hematopoietic stem cells from three different angles: developmental, adulthood and aging. The meeting, aptly named 'Hematopoietic stem cells: from the embryo to the aging organism' also covered cutting-edge technologies applied to this subject, such as single-cell analysis, reprogramming and imaging. This Meeting review summarizes the exciting work that was presented and covers the main themes that emerged from the meeting. PMID- 27702781 TI - Differential Phasing between Circadian Clocks in the Brain and Peripheral Organs in Humans. AB - The daily timing of mammalian physiology is coordinated by circadian clocks throughout the body. Although measurements of clock gene expression indicate that these clocks in mice are normally in phase with each other, the situation in humans remains unclear. We used publicly available data from five studies, comprising over 1000 samples, to compare the phasing of circadian gene expression in human brain and human blood. Surprisingly, after controlling for age, clock gene expression in brain was phase-delayed by ~8.5 h relative to that of blood. We then examined clock gene expression in two additional human organs and in organs from nine other mammalian species, as well as in the suprachiasmatic nucleus (SCN). In most tissues outside the SCN, the expression of clock gene orthologs showed a phase difference of ~12 h between diurnal and nocturnal species. The exception to this pattern was human brain, whose phasing resembled that of the SCN. Our results highlight the value of a multi-tissue, multi-species meta-analysis, and have implications for our understanding of the human circadian system. PMID- 27702784 TI - Ebi modulates wing growth by ubiquitin-dependent downregulation of Crumbs in Drosophila. AB - Notch signaling at the dorsoventral (DV) boundary is essential for patterning and growth of wings in Drosophila The WD40 domain protein Ebi has been implicated in the regulation of Notch signaling at the DV boundary. Here we show that Ebi regulates wing growth by antagonizing the function of the transmembrane protein Crumbs (Crb). Ebi physically binds to the extracellular domain of Crb (Crbext), and this interaction is specifically mediated by WD40 repeats 7-8 of Ebi and a laminin G domain of Crbext Wing notching resulting from reduced levels of Ebi is suppressed by decreasing the Crb function. Consistent with this antagonistic genetic relationship, Ebi knockdown in the DV boundary elevates the Crb protein level. Furthermore, we show that Ebi is required for downregulation of Crb by ubiquitylation. Taken together, we propose that the interplay of Crb expression in the DV boundary and ubiquitin-dependent Crb downregulation by Ebi provides a mechanism for the maintenance of Notch signaling during wing development. PMID- 27702783 TI - Making sense out of spinal cord somatosensory development. AB - The spinal cord integrates and relays somatosensory input, leading to complex motor responses. Research over the past couple of decades has identified transcription factor networks that function during development to define and instruct the generation of diverse neuronal populations within the spinal cord. A number of studies have now started to connect these developmentally defined populations with their roles in somatosensory circuits. Here, we review our current understanding of how neuronal diversity in the dorsal spinal cord is generated and we discuss the logic underlying how these neurons form the basis of somatosensory circuits. PMID- 27702785 TI - Inhibition of Shh signalling in the chick wing gives insights into digit patterning and evolution. AB - In an influential model of pattern formation, a gradient of Sonic hedgehog (Shh) signalling in the chick wing bud specifies cells with three antero-posterior positional values, which give rise to three morphologically different digits by a self-organizing mechanism with Turing-like properties. However, as four of the five digits of the mouse limb are morphologically similar in terms of phalangeal pattern, it has been suggested that self-organization alone could be sufficient. Here, we show that inhibition of Shh signalling at a specific stage of chick wing development results in a pattern of four digits, three of which can have the same number of phalanges. These patterning changes are dependent on a posterior extension of the apical ectodermal ridge, and this also allows the additional digit to arise from the Shh-producing cells of the polarizing region - an ability lost in ancestral theropod dinosaurs. Our analyses reveal that, if the specification of antero-posterior positional values is curtailed, self organization can then produce several digits with the same number of phalanges. We present a model that may give important insights into how the number of digits and phalanges has diverged during the evolution of avian and mammalian limbs. PMID- 27702786 TI - cAMP-dependent protein kinase A (PKA) regulates angiogenesis by modulating tip cell behavior in a Notch-independent manner. AB - cAMP-dependent protein kinase A (PKA) is a ubiquitously expressed serine/threonine kinase that regulates a variety of cellular functions. Here, we demonstrate that endothelial PKA activity is essential for vascular development, specifically regulating the transition from sprouting to stabilization of nascent vessels. Inhibition of endothelial PKA by endothelial cell-specific expression of dominant-negative PKA in mice led to perturbed vascular development, hemorrhage and embryonic lethality at mid-gestation. During perinatal retinal angiogenesis, inhibition of PKA resulted in hypersprouting as a result of increased numbers of tip cells. In zebrafish, cell autonomous PKA inhibition also increased and sustained endothelial cell motility, driving cells to become tip cells. Although these effects of PKA inhibition were highly reminiscent of Notch inhibition effects, our data demonstrate that PKA and Notch independently regulate tip and stalk cell formation and behavior.

AB - BACKGROUND AND OBJECTIVE: The incidence of cancer is rising in Iran, and hence it is important to assess the accuracy of the Iranian cancer registry dataset. In this study, the completeness of the cancer registry in the Kohgiluyeh and Boyer Ahmad (K&B) province is evaluated. METHOD: The data of registered cases of cancer of people who were living in the K&B province at the time of diagnosis were obtained from the provincial cancer registry offices in K&B, Fars and all other neighbouring provinces. A capture-recapture method along with log-linear statistical modelling were used for analysis. RESULTS: The results indicated that of 2029 known cases of cancer, only 1400 (31%) were registered by the K&B cancer registry office. Age-adjusted incidence rates for all common types of cancer rose from 307.0 per 100,000 (95% confidence interval (CI); 293.8, 320.3, based on observed cases) to 376.4 per 100,000 (95% CI; 361.7, 391.1, based on expected number of cases estimated by capture-recapture analysis) ( p < 0.01). The completeness of cancer registry data varied significantly for different types of cancer. CONCLUSION: Results suggest that the provincial cancer dataset, which is a part of the national cancer registry programme, is neither complete nor representative. A major improvement in case finding, registry procedures and effective data sharing by provincial cancer registry offices is needed in order to provide valid data for epidemiology of cancer in Iran. PMID- 27702788 TI - Mapping a multiplexed zoo of mRNA expression. AB - In situ hybridization methods are used across the biological sciences to map mRNA expression within intact specimens. Multiplexed experiments, in which multiple target mRNAs are mapped in a single sample, are essential for studying regulatory interactions, but remain cumbersome in most model organisms. Programmable in situ amplifiers based on the mechanism of hybridization chain reaction (HCR) overcome this longstanding challenge by operating independently within a sample, enabling multiplexed experiments to be performed with an experimental timeline independent of the number of target mRNAs. To assist biologists working across a broad spectrum of organisms, we demonstrate multiplexed in situ HCR in diverse imaging settings: bacteria, whole-mount nematode larvae, whole-mount fruit fly embryos, whole-mount sea urchin embryos, whole-mount zebrafish larvae, whole-mount chicken embryos, whole-mount mouse embryos and formalin-fixed paraffin-embedded human tissue sections. In addition to straightforward multiplexing, in situ HCR enables deep sample penetration, high contrast and subcellular resolution, providing an incisive tool for the study of interlaced and overlapping expression patterns, with implications for research communities across the biological sciences. PMID- 27702787 TI - Complex cis-regulatory landscape of the insulin receptor gene underlies the broad expression of a central signaling regulator. AB - Insulin signaling plays key roles in development, growth and metabolism through dynamic control of glucose uptake, global protein translation and transcriptional regulation. Altered levels of insulin signaling are known to play key roles in development and disease, yet the molecular basis of such differential signaling remains obscure. Expression of the insulin receptor (InR) gene itself appears to play an important role, but the nature of the molecular wiring controlling InR transcription has not been elucidated. We characterized the regulatory elements driving Drosophila InR expression and found that the generally broad expression of this gene is belied by complex individual switch elements, the dynamic regulation of which reflects direct and indirect contributions of FOXO, EcR, Rbf and additional transcription factors through redundant elements dispersed throughout ~40 kb of non-coding regions. The control of InR transcription in response to nutritional and tissue-specific inputs represents an integration of multiple cis-regulatory elements, the structure and function of which may have been sculpted by evolutionary selection to provide a highly tailored set of signaling responses on developmental and tissue-specific levels. PMID- 27702792 TI - How can hospitals better protect the privacy of electronic medical records? Perspectives from staff members of health information management departments. AB - PURPOSE: The adoption of electronic medical records (EMR) is expected to better improve overall healthcare quality and to offset the financial pressure of excessive administrative burden. However, safeguarding EMR against potentially hostile security breaches from both inside and outside healthcare facilities has created increased patients' privacy concerns from all sides. The aim of our study was to examine the influencing factors of privacy protection for EMR by healthcare professionals. METHOD: We used survey methodology to collect questionnaire responses from staff members in health information management departments among nine Taiwanese hospitals active in EMR utilisation. A total of 209 valid responses were collected in 2014. We used partial least squares for analysing the collected data. RESULTS: Perceived benefits, perceived barriers, self-efficacy and cues to action were found to have a significant association with intention to protect EMR privacy, while perceived susceptibility and perceived severity were not. CONCLUSION: Based on the findings obtained, we suggest that hospitals should provide continuous ethics awareness training to relevant staff and design more effective strategies for improving the protection of EMR privacy in their charge. Further practical and research implications are also discussed. PMID- 27702793 TI - Candida tropicalis biofilm and human epithelium invasion is highly influenced by environmental pH. AB - OBJECTIVE: The main goal of this study was to investigate the role of pH on Candida tropicalis virulence determinants, namely the ability to form biofilms and to colonize/invade reconstituted human vaginal epithelia. METHODS: Biofilm formation was evaluated by enumeration of cultivable cells, total biomass quantification and structural analysis by scanning electron microscopy and confocal laser scanning microscopy. Candida tropicalis human vaginal epithelium colonization and invasiveness were examined qualitatively by epifluorescence microscopy and quantitatively by a novel quantitative real-time PCR protocol for Candida quantification in tissues. RESULTS: The results revealed that environmental pH influences C. tropicalis biofilm formation as well as the colonization and potential to invade human epithelium with intensification at neutral and alkaline conditions compared to acidic conditions. CONCLUSIONS: For the first time, we have demonstrated that C. tropicalis biofilm formation and invasion is highly influenced by environmental pH.

PMID- 27702796 TI - Safety of extending screening intervals beyond five years in cervical screening programmes with testing for high risk human papillomavirus: 14 year follow-up of population based randomised cohort in the Netherlands. AB - OBJECTIVES: To provide an early risk assessment of extending screening intervals beyond five years for a human papillomavirus (HPV) based cervical screening programme in the Netherlands. DESIGN: 14 year follow-up of a population based randomised cohort from the POBASCAM randomised trial. SETTING: Organised cervical screening in the Netherlands, based on a programme of three screening rounds (each round done every five years). PARTICIPANTS: 43 339 women aged 29-61 years with a negative HPV and/or negative cytology test participating in the POBASCAM trial. INTERVENTIONS: Women randomly assigned to HPV and cytology co testing (intervention) or cytology testing only (control), and managed accordingly. MAIN OUTCOME MEASURES: Cumulative incidence of cervical cancer and cervical intraepithelial neoplasia (CIN) grade 3 or worse (CIN3+). Associations with age were expressed as incidence rate ratios. In HPV positive women, reductions in CIN3+ incidence after negative cytology, HPV type 16/18 genotyping, and/or repeat cytology were estimated. RESULTS: The cumulative incidence of cervical cancer (0.09%) and CIN3+ (0.56%) among HPV negative women in the intervention group after three rounds of screening were similar to the cumulative among women with negative cytology in the control group after two rounds (0.09% and 0.69%, respectively). Cervical cancer and CIN3+ risk ratios were 0.97 (95% confidence interval 0.41 to 2.31, P=0.95) and 0.82 (0.62 to 1.09, P=0.17), respectively. CIN3+ incidence was 72.2% (95% confidence interval 61.6% to 79.9%, P<0.001) lower among HPV negative women aged at least 40 years than among younger women. No significant association between cervical cancer incidence and age could be demonstrated. CIN3+ incidence among HPV positive women with negative cytology, HPV 16/18 genotyping, and/or repeat cytology was 10.4 (95% confidence interval 5.9 to 18.4) times higher than among HPV negative women. CONCLUSIONS: Long term incidences of cervical cancer and CIN3+ were low among HPV negative women in this study cohort, and supports an extension of the cervical screening interval beyond five years for women aged 40 years and older. HPV positive women with subsequent negative cytology, HPV16/18 genotyping, and/or repeat cytology have at least a fivefold higher risk of CIN3+ than HPV negative women, indicating that HPV based programmes with long intervals (>five years) should be implemented with risk stratification.Trial registration POBASCAM trial number ISRCTN20781131. PMID- 27702795 TI - Prevention of polymicrobial biofilms composed of Pseudomonas aeruginosa and pathogenic fungi by essential oils from selected Citrus species. AB - Mixed microbial infections caused by Pseudomonas aeruginosa and pathogenic fungi are commonly found in patients with chronic infections and constitute a significant health care burden. The aim of this study was to address the potential polymicrobial antibiofilm activity of pompia and grapefruit essential oils (EOs). The mechanism of antimicrobial activity of EOs was analysed. EOs of pompia and grapefruit inhibited fungal growth with MIC concentrations between 50 and 250 mg L-1, whereas no effect on P. aeruginosa growth was observed. Both citrus EOs inhibited formation of bacterial and fungal monomicrobial biofilms in concentrations of 50 mg L-1 and were efficient in potentiating the activity of clinically used antimicrobials in vitro The concentration of 10 mg L-1 EOs inhibited mixed biofilm formation composed of P. aeruginosa and Aspergillus fumigatus or Scedosporium apiospermum Citrus EOs affected quorum sensing in P. aeruginosa and caused fast permeabilisation of Candida albicans membrane. Pompia and grapefruit EOs potently inhibited biofilm formation and could be used for the control of common polymicrobial infections. PMID- 27702797 TI - Case series of octogenarians with sickle cell disease. PMID- 27702800 TI - Excellent T-cell reconstitution and survival depend on low ATG exposure after pediatric cord blood transplantation. AB - Successful immune reconstitution (IR) is associated with improved outcomes following pediatric cord blood transplantation (CBT). Usage and timing of anti thymocyte globulin (ATG), introduced to the conditioning to prevent graft-versus host disease and graft failure, negatively influences T-cell IR. We studied the relationships among ATG exposure, IR, and clinical outcomes. All pediatric patients receiving a first CBT between 2004 and 2015 at the University Medical Center Utrecht were included. ATG-exposure measures were determined with a validated pharmacokinetics model. Main outcome of interest was early CD4+ IR, defined as CD4+ T-cell counts >50 * 106/L twice within 100 days after CBT. Other outcomes of interest included event-free survival (EFS). Cox proportional-hazard and Fine-Gray competing-risk models were used. A total of 137 patients, with a median age of 7.4 years (range, 0.2-22.7), were included, of whom 82% received ATG. Area under the curve (AUC) of ATG after infusion of the cord blood transplant predicted successful CD4+ IR. Adjusted probability on CD4+ IR was reduced by 26% for every 10-point increase in AUC after CBT (hazard ratio [HR], 0.974; P < .0001). The chance of EFS was higher in patients with successful CD4+ IR (HR, 0.26; P < .0001) and lower ATG exposure after CBT (HR, 1.005; P = .0071). This study stresses the importance of early CD4+ IR after CBT, which can be achieved by reducing the exposure to ATG after CBT. Individualized dosing of ATG to reach optimal exposure or, in selected patients, omission of ATG may contribute to improved outcomes in pediatric CBT. PMID- 27702798 TI - miR-125b controls monocyte adaptation to inflammation through mitochondrial metabolism and dynamics. AB - Metabolic changes drive monocyte differentiation and fate. Although abnormal mitochondria metabolism and innate immune responses participate in the pathogenesis of many inflammatory disorders, molecular events regulating mitochondrial activity to control life and death in monocytes remain poorly understood. We show here that, in human monocytes, microRNA-125b (miR-125b) attenuates the mitochondrial respiration through the silencing of the BH3-only proapoptotic protein BIK and promotes the elongation of the mitochondrial network through the targeting of the mitochondrial fission process 1 protein MTP18, leading to apoptosis. Proinflammatory activation of monocyte-derived macrophages is associated with a concomitant increase in miR-125b expression and decrease in BIK and MTP18 expression, which lead to reduced oxidative phosphorylation and enhanced mitochondrial fusion. In a chronic inflammatory systemic disorder, CD14+ blood monocytes display reduced miR-125b expression as compared with healthy controls, inversely correlated with BIK and MTP18 messenger RNA expression. Our findings not only identify BIK and MTP18 as novel targets for miR-125b that control mitochondrial metabolism and dynamics, respectively, but also reveal a novel function for miR-125b in regulating metabolic adaptation of monocytes to inflammation. Together, these data unravel new molecular mechanisms for a proapoptotic role of miR-125b in monocytes and identify potential targets for interfering with excessive inflammatory activation of monocytes in inflammatory disorders. PMID- 27702802 TI - Dynamic disulfide/thiol homeostasis in lead exposure denoted by a novel method. AB - Lead is a toxic heavy metal, and prevention of human exposure to lead has not been accomplished yet. The toxicity of lead is continually being investigated, and the molecular mechanisms of its toxicity are still being revealed. In this study, we used a novel method to examine thiol (SH)/disulfide homeostasis in workers who were occupationally exposed to lead. A total of 80 such workers and 70 control subjects were evaluated, and their native and total SH values were measured in serum using a novel method; their blood lead levels were also assessed. The novel method used for SH measurements was based on the principle of measuring native SH, after which disulfide bonds were reduced and total SHs were measured. These measurements allowed us to calculate disulfide amounts, disulfide/total SH percent ratios, disulfide/native SH percent ratios, and native SH /total SH percent ratios. We found that disulfide levels were significantly higher in workers who were exposed to lead (21.08(11.1-53.6) vs. 17.9(1.7-25), p < 0.001). Additionally, the disulfide/native SH and disulfide/total SH percent ratios were higher in exposed workers, while the native SH/total SH percent ratios were higher in the control subjects. Furthermore, the lead and disulfide levels showed a positive correlation, with p < 0.001 and a correlation coefficient of 0.378. Finally, the novel method used in this study successfully showed a switch from SH to disulfide after lead exposure, and the method is fully automated, easy, cheap, reliable, and reproducible. Use of this method in future cases may provide valuable insights into the management of lead exposure. PMID- 27702799 TI - Randomized phase 2 trial of ixazomib and dexamethasone in relapsed multiple myeloma not refractory to bortezomib. AB - Proteasome inhibitors have become an integral part of myeloma therapy. Considerable efforts have gone into optimizing this therapeutic approach to obtain maximal proteasome inhibition with least toxicity. Ixazomib is the first oral proteasome inhibitor to enter the clinic and has been studied as a single agent as well as in various combinations. The current trial was designed to examine the efficacy and toxicity of combining 2 different doses of ixazomib (4 mg and 5.5 mg given weekly for 3 of 4 weeks) with 40 mg weekly of dexamethasone, in relapsed myeloma. Seventy patients were enrolled, 35 patients randomly assigned to each ixazomib dose. Overall, 30 (43%; 95% confidence interval, 31-55) of the patients achieved a confirmed partial response or better, with 31% achieving a response with 4 mg and 54% with 5.5 mg of ixazomib. The median event free survival (EFS) for the entire study population was 8.4 months; 1-year overall survival was 96%. The EFS was 5.7 months for patients with prior bortezomib exposure and 11.0 months for bortezomib-naive patients. A grade 3 or 4 adverse event considered at least possibly related to treatment was seen in 11 (32%) patients at 4 mg and in 21 (60%) at 5.5 mg. Dose reductions were more frequent with 5.5 mg dose. Overall, the ixazomib with dexamethasone has good efficacy in relapsed myeloma, is well-tolerated and with higher response rate at 5.5 mg, albeit with more toxicity. This study was registered at www.clinicaltrials.gov as #NCT01415882. PMID- 27702801 TI - LXR agonist treatment of blastic plasmacytoid dendritic cell neoplasm restores cholesterol efflux and triggers apoptosis. AB - Blastic plasmacytoid dendritic cell (PDC) neoplasm (BPDCN) is an aggressive hematological malignancy with a poor prognosis that derives from PDCs. No consensus for optimal treatment modalities is available today and the full characterization of this leukemia is still emerging. We identified here a BPDCN specific transcriptomic profile when compared with those of acute myeloid leukemia and T-acute lymphoblastic leukemia, as well as the transcriptomic signature of primary PDCs. This BPDCN gene signature identified a dysregulation of genes involved in cholesterol homeostasis, some of them being liver X receptor (LXR) target genes. LXR agonist treatment of primary BPDCN cells and BPDCN cell lines restored LXR target gene expression and increased cholesterol efflux via the upregulation of adenosine triphosphate-binding cassette (ABC) transporters, ABCA1 and ABCG1. LXR agonist treatment was responsible for limiting BPDCN cell proliferation and inducing intrinsic apoptotic cell death. LXR activation in BPDCN cells was shown to interfere with 3 signaling pathways associated with leukemic cell survival, namely: NF-kappaB activation, as well as Akt and STAT5 phosphorylation in response to the BPDCN growth/survival factor interleukin-3. These effects were increased by the stimulation of cholesterol efflux through a lipid acceptor, the apolipoprotein A1. In vivo experiments using a mouse model of BPDCN cell xenograft revealed a decrease of leukemic cell infiltration and BPDCN induced cytopenia associated with increased survival after LXR agonist treatment. This demonstrates that cholesterol homeostasis is modified in BPDCN and can be normalized by treatment with LXR agonists which can be proposed as a new therapeutic approach. PMID- 27702803 TI - Is an Oral Anticoagulant Necessary for Young Atrial Fibrillation Patients With a CHA2DS2-VASc Score of 1 (Men) or 2 (Women)? AB - BACKGROUND: Recent studies demonstrated that oral anticoagulants (OACs) should be considered for patients with atrial fibrillation and 1 risk factor in addition to sex. Because age is an important determinant of ischemic stroke, the strategy for stroke prevention may be different for these patients in different age strata. The aim of this study was to investigate whether OACs should be considered for patients aged 20 to 49 years with atrial fibrillation and a CHA2DS2-VASc score of 1 (men) or 2 (women). METHODS AND RESULTS: Using the Taiwan National Health Insurance Research Database, 7374 male patients with atrial fibrillation and a CHA2DS2-VASc score of 1 and 4461 female patients with atrial fibrillation and a CHA2DS2-VASc score of 2 and all without antithrombotic therapies were identified and stratified into 3 groups by age. The threshold for the initiation of OACs for stroke prevention was set at a stroke rate of 1.7% per year for warfarin and 0.9% per year for non-vitamin K antagonist OACs. Among male patients aged 20 to 49 years with a CHA2DS2-VASc score of 1, the risk of ischemic stroke was 1.30% per year and ranged from 0.94% per year for those with hypertension to 1.71% for those with congestive heart failure. Among female patients aged 20 to 49 years with a CHA2DS2-VASc score of 2, the risk of ischemic stroke was 1.40% per year and ranged from 1.11% per year for those with hypertension to 1.67% for those with congestive heart failure. CONCLUSIONS: For atrial fibrillation patients aged 20 to 49 years with 1 risk factor in addition to sex, non-vitamin K antagonist OACs should be considered for stroke prevention to minimize the risk of a potentially fatal or disabling event. PMID- 27702804 TI - Hemodynamic Tandem Intracranial Lesions on Magnetic Resonance Angiography in Patients Undergoing Carotid Endarterectomy. AB - BACKGROUND: Hemodynamic tandem intracranial lesions (TILs) on intracranial magnetic resonance angiography, which develop flow dependently, have been overlooked clinically in patients undergoing carotid endarterectomy. As they represent severe baseline hemodynamic compromise at the segment, they may be associated with distinctive clinical outcomes. METHODS AND RESULTS: We assessed 304 consecutive carotid endarterectomy cases treated over 3 years. Included cases had both preoperative and postoperative intracranial 3-dimensional time-of-flight magnetic resonance angiography, of which signal intensities are flow dependent, and postoperative diffusion-weighted imaging (<=3 days following carotid endarterectomy). Preoperative TILs in the ipsilateral intracranial arteries were evaluated by the presence of nonexclusive components: focal stenosis (>50%), diffuse stenosis (>50%), and decreased signal intensities (>50%). The components showing postoperative normalization were considered hemodynamic. TILs with hemodynamic components were defined as hemodynamic TILs, while others as consistent TILs. Baseline characteristics and postoperative outcomes were analyzed among 3 groups: no TILs, consistent TILs, and hemodynamic TILs. Preoperative TILs were identified in 104 (34.2%) cases; 54 (17.8%) had hemodynamic components. Diffuse stenosis and decreased signal intensities were usually reversed postoperatively. Patients with hemodynamic TILs tended to have severe proximal carotid stenosis and recent strokes (<=14 days). For the outcome, hemodynamic TILs were independently associated with the advent of postoperative ischemic lesions on diffusion-weighted imaging (odds ratio: 2.50; 95% CI, 1.20 5.20). CONCLUSIONS: In patients undergoing carotid endarterectomy, a significant number of preoperative TILs demonstrated hemodynamic components, which were reversed postoperatively. The presence of such components was distinctively associated with the postoperative incidence of new ischemic lesions. PMID- 27702806 TI - Changes in white spot lesions following post-orthodontic weekly application of 1.25 per cent fluoride gel over 6 months-a randomized placebo-controlled clinical trial. Part I: photographic data evaluation. AB - Background: White spot lesions (WSLs) are a frequent side-effect of multibracket appliance treatment. The effect of local fluoridation on post-orthodontic WSL is however inconclusive. Objective: Assessment of WSL changes in response to weekly 1.25 per cent fluoride gel application after multibracket appliance treatment. Trial design: Randomized, single-centre, double-blind, parallel-group, placebo controlled study. Participants: Patients with not less than 1 WSL (modified score 1 or 2) on not less than 1 upper front teeth after debonding. Interventions: Professional fluoride/placebo gel application during weeks 1-2; self-administered home application (weeks 3-24). Outcomes: Photographic WSL assessment (dimension and luminance) of the upper front teeth (T0-T5). Randomization: Random assignment to test (n = 23) or placebo group (n = 23) using a sequentially numbered list (random allocation sequence generated for 50 subjects in 25 blocks of 2 subjects each). Recruitment: The clinical study duration lasted from March 2011 to September 2013. Blinding: Unblinding was performed after complete data evaluation. Numbers analysed: Intent-to-treat analysis set comprising 39 participants (test: n = 21, placebo: n = 18). Outcome: Dimensional WSL quantification showed limited reliability. Luminance improvement (%) of WSL, however, was seen after 6 months (test/placebo: tooth 12, 24.8/18.0; tooth 11, 38.4/35.4; tooth 21, 39.6/38.3; and tooth 22, 15.2/25.0). No statistically significant group difference existed. Data suggest that WSLs are difficult to measure with respect to reliability and repeatability and methods for monitoring WSLs in clinical trials require improvement/validation. Harms: Similar adverse events occurred in both groups; none was classified as possibly related to the study product. Limitations: The number of dropouts was higher than expected and the socio-economic status was not assessed. Furthermore, the unknown level of compliance during the home application phase must be considered as limitation. Conclusion: Based on the results of this study, no difference could be detected with respect to the development of WSL under post-orthodontic high-dose fluoride treatment. Registration: The study was registered with ClinicalTrials.gov (Identifier: NCT01329731). Protocol: The protocol wasn't published before trial commencement. PMID- 27702805 TI - A Pilot Randomized Controlled Trial of the Feasibility, Acceptability, and Impact of Giving Information on Personalized Genomic Risk of Melanoma to the Public. AB - BACKGROUND: Communication of personalized melanoma genomic risk information may improve melanoma prevention behaviors. METHODS: We evaluated the feasibility and acceptability of communicating personalized genomic risk of melanoma to the public and its preliminary impact on behaviors and psychosocial outcomes. One hundred eighteen people aged 22 to 69 years provided a saliva sample and were randomized to the control (nonpersonalized educational materials) or intervention (personalized booklet presenting melanoma genomic risk as absolute and relative risks and a risk category based on variants in 21 genes, telephone-based genetic counseling, and nonpersonalized educational materials). Intention-to-treat analyses overall and by-risk category were conducted using ANCOVA adjusted for baseline values. RESULTS: Consent to participate was 41%, 99% were successfully genotyped, and 92% completed 3-month follow-up. Intervention participants reported high satisfaction with the personalized booklet (mean = 8.6, SD = 1.6; on a 0-10 scale) and genetic counseling (mean = 8.1, SD = 2.2). No significant behavioral effects at 3-month follow-up were identified between intervention and control groups overall: objectively measured standard erythemal doses per day [ 16%; 95% confidence interval (CI), -43% to 24%] and sun protection index (0.05; 95% CI, -0.07 to 0.18). There was increased confidence identifying melanoma at 3 months (0.40; 95% CI, 0.10-0.69). Stratified by risk category, effect sizes for intentional tanning and some individual sun protection items appeared stronger for the average-risk group. There were no appreciable group differences in skin cancer-related worry or psychologic distress. CONCLUSIONS: Our results demonstrate feasibility and acceptability of providing personalized genomic risk of melanoma to the public. IMPACT: Genomic risk information has potential as a melanoma prevention strategy. Cancer Epidemiol Biomarkers Prev; 26(2); 212-21. (c)2016 AACR.

Part II: clinical data evaluation. AB - Background: White spot lesions (WSL) frequently occur as side-effect of multibracket appliance treatment. The clinical effects of local fluoridation on post-orthodontic WSL and oral health development are however inconclusive. Objective: In vivo monitoring of clinical WSL and oral health changes in response to weekly 1.25 per cent fluoride gel application after multibracket appliance treatment. Trial design: Randomized, single-centre, double-blind, parallel-group, placebo-controlled study. Participants: Patients with not less than 1 WSL (modified score 1 or 2) on not less than 1 upper front teeth after debonding. Interventions: Professional fluoride/placebo gel application during weeks 1-2; self-administered home application (weeks 3-24). Outcomes: Clinical evaluation of WSL index, lesion activity, plaque index, gingival bleeding index, and decayed, missing, and filled teeth index as well as saliva buffer capacity and stimulated salivary flow rate (T0-T5). Randomization: Random assignment to test (n = 23) or placebo group (n = 23) using a sequentially numbered list (random allocation sequence generated for 50 subjects in 25 blocks of 2 subjects each). Recruitment: The clinical study duration lasted from March 2011 to September 2013. Blinding: Unblinding was performed after complete data evaluation. Numbers analysed: Intention-to-treat analysis set comprised 39 participants (test: n = 21, placebo: n = 18). Outcome: No clinical parameter except stimulated salivary flow rate (fluoride group: 1.1ml/min, placebo group: 0.74ml/min; P = 0.022) showed a statistically significant group difference after 24 weeks. Harms: Several adverse events occurred similarly frequent in both groups; none was classified as possibly related to the study product. Limitations: The number of dropouts was higher than expected and the socio-economic status was not assessed. Furthermore, the unknown level of compliance during the home application phase must be considered as limitation.

PMID- 27702810 TI - Altered Global Signal Topography in Schizophrenia. AB - Schizophrenia (SCZ) is a disabling neuropsychiatric disease associated with disruptions across distributed neural systems. Resting-state functional magnetic resonance imaging has identified extensive abnormalities in the blood-oxygen level-dependent signal in SCZ patients, including alterations in the average signal over the brain-i.e. the "global" signal (GS). It remains unknown, however, if these "global" alterations occur pervasively or follow a spatially preferential pattern. This study presents the first network-by-network quantification of GS topography in healthy subjects and SCZ patients. We observed a nonuniform GS contribution in healthy comparison subjects, whereby sensory areas exhibited the largest GS component. In SCZ patients, we identified preferential GS representation increases across association regions, while sensory regions showed preferential reductions. GS representation in sensory versus association cortices was strongly anti-correlated in healthy subjects. This anti-correlated relationship was markedly reduced in SCZ. Such shifts in GS topography may underlie profound alterations in neural information flow in SCZ, informing development of pharmacotherapies. PMID- 27702811 TI - Within-Category Decoding of Information in Different Attentional States in Short Term Memory. AB - A long-standing assumption of cognitive neuroscience has been that working memory (WM) is accomplished by sustained, elevated neural activity. More recently, theories of WM have expanded this view by describing different attentional states in WM with differing activation levels. Several studies have used multivariate pattern analysis (MVPA) of functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) data to study neural activity corresponding to these WM states. Intriguingly, no evidence was found for active neural representations for information held in WM outside the focus of attention ("unattended memory items," UMIs), suggesting that only attended memory items (AMIs) are accompanied by an active trace. However, these results depended on category-level decoding, which lacks sensitivity to neural representations of individual items. Therefore, we employed a WM task in which subjects remembered the directions of motion of two dot arrays, with a retrocue indicating which was relevant for an imminent memory probe (the AMI). This design allowed MVPA decoding of delay-period fMRI signal at the stimulus-item level, affording a more sensitive test of the neural representation of UMIs. Whereas evidence for the AMI was reliably high, evidence for the UMI dropped to baseline, consistent with the notion that different WM attentional states may have qualitatively different mechanisms of retention. PMID- 27702812 TI - An Electrophysiological Index of Perceptual Goodness. AB - A traditional line of work starting with the Gestalt school has shown that patterns vary in strength and salience; a difference in "Perceptual goodness." The Holographic weight of evidence model quantifies goodness of visual regularities. The key formula states that W = E/N, where E is number of holographic identities in a pattern and N is number of elements. We tested whether W predicts the amplitude of the neural response to regularity in an extrastriate symmetry-sensitive network. We recorded an Event Related Potential (ERP) generated by symmetry called the Sustained Posterior Negativity (SPN). First, we reanalyzed the published work and found that W explained most variance in SPN amplitude. Then in four new studies, we confirmed specific predictions of the holographic model regarding 1) the differential effects of numerosity on reflection and repetition, 2) the similarity between reflection and Glass patterns, 3) multiple symmetries, and 4) symmetry and anti-symmetry. In all cases, the holographic approach predicted SPN amplitude remarkably well; particularly in an early window around 300-400 ms post stimulus onset. Although the holographic model was not conceived as a model of neural processing, it captures many details of the brain response to symmetry.

AB - The genomes of the two plant organelles encode for a relatively small number of proteins. Thus, nuclear genes encode the vast majority of their proteome. Organelle-to-nucleus communication takes place through retrograde signaling (RS) pathways. Signals relayed through RS pathways have an impact on nuclear gene expression but their target-genes remain elusive in a normal state of the cell (considering that only mutants and stress have been used so far). Here, we use maize cytolines as an alternative. The nucleus of a donor line was transferred into two other cytoplasmic environments through at least nine back-crosses, in a time-span of > 10 years. The transcriptomes of the resulting cytolines were sequenced and compared. There are 96 differentially regulated nuclear genes in two cytoplasm-donor lines when compared with their nucleus-donor. They are expressed throughout plant development, in various tissues and organs. One-third of the 96 proteins have a human homolog, stressing their potential role in mitochondrial RS. We also identified syntenic orthologous genes in four other grasses and homologous genes in Arabidopsis thaliana These findings contribute to the paradigm we use to describe the RS in plants. The 96 nuclear genes identified here are not differentially regulated as a result of mutation, or any kind of stress. They are rather key players of the organelle-to-nucleus communication in a normal state of the cell. PMID- 27702814 TI - LINEs between Species: Evolutionary Dynamics of LINE-1 Retrotransposons across the Eukaryotic Tree of Life. AB - LINE-1 (L1) retrotransposons are dynamic elements. They have the potential to cause great genomic change because of their ability to 'jump' around the genome and amplify themselves, resulting in the duplication and rearrangement of regulatory DNA. Active L1, in particular, are often thought of as tightly constrained, homologous and ubiquitous elements with well-characterized domain organization. For the past 30 years, model organisms have been used to define L1s as 6-8 kb sequences containing a 5'-UTR, two open reading frames working harmoniously in cis, and a 3'-UTR with a polyA tail. In this study, we demonstrate the remarkable and overlooked diversity of L1s via a comprehensive phylogenetic analysis of elements from over 500 species from widely divergent branches of the tree of life. The rapid and recent growth of L1 elements in mammalian species is juxtaposed against the diverse lineages found in other metazoans and plants. In fact, some of these previously unexplored mammalian species (e.g. snub-nosed monkey, minke whale) exhibit L1 retrotranspositional 'hyperactivity' far surpassing that of human or mouse. In contrast, non-mammalian L1s have become so varied that the current classification system seems to inadequately capture their structural characteristics. Our findings illustrate how both long-term inherited evolutionary patterns and random bursts of activity in individual species can significantly alter genomes, highlighting the importance of L1 dynamics in eukaryotes. PMID- 27702815 TI - Selective Landscapes in newt Immune Genes Inferred from Patterns of Nucleotide Variation. AB - Host-pathogen interactions may result in either directional selection or in pressure for the maintenance of polymorphism at the molecular level. Hence signatures of both positive and balancing selection are expected in immune genes. Because both overall selective pressure and specific targets may differ between species, large-scale population genomic studies are useful in detecting functionally important immune genes and comparing selective landscapes between taxa. Such studies are of particular interest in amphibians, a group threatened worldwide by emerging infectious diseases. Here, we present an analysis of polymorphism and divergence of 634 immune genes in two lineages of Lissotriton newts: L. montandoni and L. vulgaris graecus Variation in newt immune genes has been shaped predominantly by widespread purifying selection and strong evolutionary constraint, implying long-term importance of these genes for functioning of the immune system. The two evolutionary lineages differ in the overall strength of purifying selection which can partially be explained by demographic history but may also signal differences in long-term pathogen pressure. The prevalent constraint notwithstanding, 23 putative targets of positive selection and 11 putative targets of balancing selection were identified. The latter were detected by composite tests involving the demographic model and further validated in independent population samples. Putative targets of balancing selection encode proteins which may interact closely with pathogens but include also regulators of immune response. The identified candidates will be useful for testing whether genes affected by balancing selection are more prone to interspecific introgression than other genes in the genome. PMID- 27702816 TI - Variable Autosomal and X Divergence Near and Far from Genes Affects Estimates of Male Mutation Bias in Great Apes. AB - Male mutation bias, when more mutations are passed on via the male germline than via the female germline, is observed across mammals. One common way to infer the magnitude of male mutation bias, alpha, is to compare levels of neutral sequence divergence between genomic regions that spend different amounts of time in the male and female germline. For great apes, including human, we show that estimates of divergence are reduced in putatively unconstrained regions near genes relative to unconstrained regions far from genes. Divergence increases with increasing distance from genes on both the X chromosome and autosomes, but increases faster on the X chromosome than autosomes. As a result, ratios of X/A divergence increase with increasing distance from genes and corresponding estimates of male mutation bias are significantly higher in intergenic regions near genes versus far from genes. Future studies in other species will need to carefully consider the effect that genomic location will have on estimates of male mutation bias. PMID- 27702817 TI - Ovarian Cancers Harbor Defects in Nonhomologous End Joining Resulting in Resistance to Rucaparib. AB - Purpose: DNA damage defects are common in ovarian cancer and can be used to stratify treatment. Although most work has focused on homologous recombination (HR), DNA double-strand breaks are repaired primarily by nonhomologous end joining (NHEJ). Defects in NHEJ have been shown to contribute to genomic instability and have been associated with the development of chemoresistance.Experimental Design: NHEJ was assessed in a panel of ovarian cancer cell lines and 47 primary ascetic-derived ovarian cancer cultures, by measuring the ability of cell extracts to end-join linearized plasmid monomers into multimers. mRNA and protein expression of components of NHEJ was determined using RT-qPCR and Western blotting. Cytotoxicities of cisplatin and the PARP inhibitor rucaparib were assessed using sulforhodamine B (SRB) assays. HR function was assessed using gammaH2AX/RAD51 foci assay.Results: NHEJ was defective (D) in four of six cell lines and 20 of 47 primary cultures. NHEJ function was independent of HR competence (C). NHEJD cultures were resistant to rucaparib (P = 0.0022). When HR and NHEJ functions were taken into account, only NHEJC/HRD cultures were sensitive to rucaparib (compared with NHEJC/HRC P = 0.034, NHEJD/HRC P = 0.0002, and NHEJD/HRD P = 0.0045). The DNA-PK inhibitor, NU7441, induced resistance to rucaparib (P = 0.014) and HR function recovery in a BRCA1-defective cell line.Conclusions: This study has shown that NHEJ is defective in 40% of ovarian cancers, which is independent of HR function and associated with resistance to PARP inhibitors in ex vivo primary cultures.

PMID- 27702818 TI - Paired High-Content Analysis of Prostate Cancer Cells in Bone Marrow and Blood Characterizes Increased Androgen Receptor Expression in Tumor Cell Clusters. AB - Purpose: Recent studies demonstrate that prostate cancer clones from different metastatic sites are dynamically represented in the blood of patients over time, suggesting that the paired evaluation of tumor cells in circulation and bone marrow, the primary target for prostate cancer metastasis, may provide complementary information.Experimental Design: We adapted our single-cell high content liquid biopsy platform to bone marrow aspirates (BMA) to concurrently identify and characterize prostate cancer cells in patients' blood and bone and thus discern features associated to tumorigenicity and dynamics of metastatic progression.Results: The incidence of tumor cells in BMAs increased as the disease advanced: 0% in biochemically recurrent (n = 52), 26% in newly diagnosed metastatic hormone-naive (n = 26), and 39% in metastatic castration-resistant prostate cancer (mCRPC; n = 63) patients, and their number was often higher than in paired blood. Tumor cell detection in metastatic patients' BMAs was concordant but 45% more sensitive than using traditional histopathologic interpretation of core bone marrow biopsies. Tumor cell clusters were more prevalent and bigger in BMAs than in blood, expressed higher levels of the androgen receptor protein per tumor cell, and were prognostic in mCRPC. Moreover, the patterns of genomic copy number variation in single tumor cells in paired blood and BMAs showed significant inter- and intrapatient heterogeneity.Conclusions: Paired analysis of single prostate cancer cells in blood and bone shows promise for clinical application and provides complementary information. The high prevalence and prognostic significance of tumor cell clusters, particularly in BMAs, suggest that these structures are key mediators of prostate cancer's metastatic progression.

AB - Peroxisome proliferator-activated receptor delta (PPAR-delta) is a nuclear receptor transcription factor that regulates gene expression during development and disease states, such as cancer. However, the precise role of PPAR-delta during tumorigenesis is not well understood. Recent data suggest that PPAR-delta may have context-specific oncogenic and tumor-suppressive roles depending on the tissue, cell-type, or diet-induced physiology in question. For example, in the intestine, pro-obesity diets, such as a high-fat diet (HFD), are associated with increased colorectal cancer incidence. Interestingly, many of the effects of an HFD in the stem and progenitor cell compartment are driven by a robust PPAR-delta program and contribute to the early steps of intestinal tumorigenesis. Importantly, the PPAR-delta pathway or its downstream mediators may serve as therapeutic intervention points or biomarkers in colon cancer that arise in patients who are obese. Although potent PPAR-delta agonists and antagonists exist, their clinical utility may be enhanced by uncovering how PPAR-delta mediates tumorigenesis in diverse tissues and cell types as well as in response to diet.

AB - Purpose: Antiendocrine therapy remains the most effective treatment for estrogen receptor-positive (ER+) breast cancer, but development of resistance is a major clinical complication. Effective targeting of mechanisms that control the loss of ER dependency in breast cancer remains elusive. We analyzed breast cancer associated fibroblasts (CAF), the largest component of the tumor microenvironment, as a factor contributing to ER expression levels and antiendocrine resistance.Experimental Design: Tissues from patients with ER+ breast cancer were analyzed for the presence of CD146-positive (CD146pos) and CD146-negative (CD146neg) fibroblasts. ER-dependent proliferation and tamoxifen sensitivity were evaluated in ER+ tumor cells cocultured with CD146pos or CD146neg fibroblasts. RNA sequencing was used to develop a high-confidence gene signature that predicts for disease recurrence in tamoxifen-treated patients with ER+ breast cancer.Results: We demonstrate that ER+ breast cancers contain two CAF subtypes defined by CD146 expression. CD146neg CAFs suppress ER expression in ER+ breast cancer cells, decrease tumor cell sensitivity to estrogen, and increase tumor cell resistance to tamoxifen therapy. Conversely, the presence of CD146pos CAFs maintains ER expression in ER+ breast cancer cells and sustains estrogen dependent proliferation and sensitivity to tamoxifen. Conditioned media from CD146pos CAFs with tamoxifen-resistant breast cancer cells are sufficient to restore tamoxifen sensitivity. Gene expression profiles of patient breast tumors with predominantly CD146neg CAFs correlate with inferior clinical response to tamoxifen and worse patient outcomes.Conclusions: Our data suggest that CAF composition contributes to treatment response and patient outcomes in ER+ breast cancer and should be considered a target for drug development.

PMID- 27702823 TI - Effects of Budesonide on Cabazitaxel Pharmacokinetics and Cabazitaxel-Induced Diarrhea: A Randomized, Open-Label Multicenter Phase II Study. AB - Purpose: Forty-seven percent of patients in the pivotal trial of cabazitaxel reported diarrhea of any grade. Aiming to reduce the incidence of diarrhea, we studied the effects of budesonide on the grade of cabazitaxel-induced diarrhea during the first two treatment cycles.Experimental Design: Between December 2011 and October 2015, 246 metastatic castration-resistant prostate cancer patients were randomized to receive standard-of-care cabazitaxel 25 mg/m2 every 3 weeks plus prednisone 10 mg/day (group CABA) or same dose/schedule of cabazitaxel with concomitant budesonide 9 mg daily during the first two treatment cycles (group BUD). The occurrence of diarrhea was reported by physicians and by patients in a diary. chi2 tests were used to compare incidence numbers. An intention-to-treat principle was used.Results: In the phase II trial, 227 patients were evaluable. Grade 2-3 diarrhea occurred in 35 patients (15%) and grade 4 diarrhea was not reported. The incidence of grade 2-3 diarrhea was comparable in both treatment groups: 14 of 113 patients in group CABA (12%) versus 21 of 114 patients in group BUD (18%; P = 0.21). Seven patients were admitted to the hospital with diarrhea (n = 5 group CABA vs. n = 2 group BUD). PSA response was seen in 30% of patients and was not affected by budesonide coadministration (P = 0.29). Also, other toxicities were not affected by budesonide coadministration.Conclusions: The incidence of cabazitaxel-induced diarrhea was notably lower than reported in the TROPIC trial and appears manageable in routine clinical practice. Budesonide coadministration did not reduce the incidence or severity of cabazitaxel-induced diarrhea. Clin Cancer Res; 23(7); 1679-83. (c)2016 AACR. PMID- 27702821 TI - Integrative Development of a TLR8 Agonist for Ovarian Cancer Chemoimmunotherapy. AB - Purpose: Immunotherapy is an emerging paradigm for the treatment of cancer, but the potential efficacy of many drugs cannot be sufficiently tested in the mouse. We sought to develop a rational combination of motolimod-a novel Toll-like receptor 8 (TLR8) agonist that stimulates robust innate immune responses in humans but diminished responses in mice-with pegylated liposomal doxorubicin (PLD), a chemotherapeutic that induces immunogenic cell death.Experimental Design: We followed an integrative pharmacologic approach including healthy human volunteers, non-human primates, NSG-HIS ("humanized immune system") mice reconstituted with human CD34+ cells, and patients with cancer to test the effects of motolimod and to assess the combination of motolimod with PLD for the treatment of ovarian cancer.Results: The pharmacodynamic effects of motolimod monotherapy in NSG-HIS mice closely mimicked those in non-human primates and healthy human subjects, whereas the effects of the motolimod/PLD combination in tumor-bearing NSG-HIS mice closely mimicked those in patients with ovarian cancer treated in a phase Ib trial (NCT01294293). The NSG-HIS mouse helped elucidate the mechanism of action of the combination and revealed a positive interaction between the two drugs in vivo The combination produced no dose-limiting toxicities in patients with ovarian cancer. Two subjects (15%) had complete responses and 7 subjects (53%) had disease stabilization. A phase II study was consequently initiated.Conclusions: These results are the first to demonstrate the value of pharmacologic approaches integrating the NSG-HIS mouse, non-human primates, and patients with cancer for the development of novel immunomodulatory anticancer agents with human specificity.

AB - Purpose: Aberrant activation of the NF-kappaB transcription factors underlies the aggressive behavior and poor outcome of pancreatic ductal adenocarcinoma (PDAC). However, clinically effective and safe NF-kappaB inhibitors are not yet available. Because NF-kappaB transcription factors can be activated by the interleukin-1 receptor-associated kinases (IRAKs) downstream of the Toll-like receptors (TLRs), but has not been explored in PDAC, we sought to investigate the role of IRAKs in the pathobiology of PDAC.Experimental Design: We examined the phosphorylation status of IRAK4 (p-IRAK4), the master regulator of TLR signaling, in PDAC cell lines, in surgical samples and commercial tissue microarray. We then performed functional studies using small-molecule IRAK1/4 inhibitor, RNA interference, and CRISPR/Cas9n techniques to delineate the role of IRAK4 in NF kappaB activity, chemoresistance, cytokine production, and growth of PDAC cells in vitro and in vivoResults: p-IRAK4 staining was detectable in the majority of PDAC lines and about 60% of human PDAC samples. The presence of p-IRAK4 strongly correlated with phospho-NF-kappaB/p65 staining in PDAC samples and is predictive of postoperative relapse and poor overall survival. Inhibition of IRAK4 potently reduced NF-kappaB activity, anchorage-independent growth, chemoresistance, and secretion of proinflammatory cytokines from PDAC cells. Both pharmacologic suppression and genetic ablation of IRAK4 greatly abolished PDAC growth in mice and augmented the therapeutic effect of gemcitabine by promoting apoptosis, reducing tumor cell proliferation and tumor fibrosis.Conclusions: Our data established IRAK4 as a novel therapeutic target for PDAC treatment. Development of potent IRAK4 inhibitors is needed for clinical testing. Clin Cancer Res; 23(7); 1748-59. (c)2016 AACR. PMID- 27702825 TI - Integrative Network-based Analysis of Colonic Detoxification Gene Expression in Ulcerative Colitis According to Smoking Status. AB - Backgrounds and Aims: The effect of cigarette smoking [CS] is ambivalent since smoking improves ulcerative colitis [UC] while it worsens Crohn's disease [CD]. Although this clinical relationship between inflammatory bowel disease [IBD] and tobacco is well established, only a few experimental works have investigated the effect of smoking on the colonic barrier homeostasis focusing on xenobiotic detoxification genes. Methods: A comprehensive and integrated comparative analysis of the global xenobiotic detoxification capacity of the normal colonic mucosa of healthy smokers [n = 8] and non-smokers [n = 9] versus the non-affected colonic mucosa of UC patients [n = 19] was performed by quantitative real-time polymerase chain reaction [qRT PCR]. The detoxification gene expression profile was analysed in CD patients [n = 18], in smoking UC patients [n = 5], and in biopsies from non-smoking UC patients cultured or not with cigarette smoke extract [n = 8]. Results: Of the 244 detoxification genes investigated, 65 were dysregulated in UC patients in comparison with healthy controls or CD patients. The expression of >= 45/65 genes was inversed by CS in biopsies of smoking UC patients in remission and in colonic explants of UC patients exposed to cigarette smoke extract. We devised a network-based data analysis approach for differentially assessing changes in genetic interactions, allowing identification of unexpected regulatory detoxification genes that may play a major role in the beneficial effect of smoking on UC. Conclusions: Non-inflamed colonic mucosa in UC is characterised by a specifically altered detoxification gene network, which is partially restored by tobacco. These mucosal signatures could be useful for developing new therapeutic strategies and biomarkers of drug response in UC.

AB - Objectives: Favourable outcomes in the repair of Ebstein's anomaly are predicated on tricuspid valve competence, right ventricular function and presence of arrhythmia. We report our experience with a single-stage, three-fold repair of Ebstein's anomaly, namely, cone reconstruction of the tricuspid valve supplemented by bidirectional cavopulmonary anastomosis and right atrial electrocautery maze. Methods: From 2010 to 2014, 37 consecutive patients with Ebstein's anomaly, median age 17.3 (9.1-56.2) years, underwent this single-stage, three-fold surgical procedure. The principal elements of the procedure include (i) cone reconstruction of the tricuspid valve, limited plication at the level of the displaced valve, insertion of a homemade annuloplasty ring, defect repair and reduction atrioplasty supplemented by (ii) right atrial electrocautery maze and (iii) bidirectional cavopulmonary anastomosis. Postoperatively, all patients were followed up regularly for a mean period of 2.3 (1-4) years by clinical, electrocardiographic and echocardiographic examinations. Results: The in-hospital mortality rate was 2.7% (1 patient) with no late deaths. Mean cardiopulmonary bypass time was 110 +/- 18.3 min and aortic cross-clamp time was 48.5 +/- 7.4 min. Echocardiographic examination showed significant improvement of valve regurgitation (P < 0.0001). NYHA functional class was I in 77.8% of the survivors and II in 22.2%. The cardiothoracic ratio decreased significantly (P < 0.05). No deleterious effects of the Glenn shunts have been reported. Sinus rhythm has remained stable in 31 patients (86.1%) during the follow-up period. Conclusions: Single-stage, three-fold repair for the management of Ebstein's anomaly offers good outcome in terms of low mortality and morbidity rates. It can achieve a durable valve-sparing repair, good functional mid-term outcomes and good quality of life among survivors. PMID- 27702824 TI - Significance of TP53 Mutation in Wilms Tumors with Diffuse Anaplasia: A Report from the Children's Oncology Group. AB - PURPOSE: To investigate the role and significance of TP53 mutation in diffusely anaplastic Wilms tumors (DAWTs). EXPERIMENTAL DESIGN: All DAWTs registered on National Wilms Tumor Study-5 (n = 118) with available samples were analyzed for TP53 mutations and copy loss. Integrative genomic analysis was performed on 39 selected DAWTs. RESULTS: Following analysis of a single random sample, 57 DAWTs (48%) demonstrated TP53 mutations, 13 (11%) copy loss without mutation, and 48 (41%) lacked both [defined as TP53-wild-type (wt)]. Patients with stage III/IV TP53-wt DAWTs (but not those with stage I/II disease) had significantly lower relapse and death rates than those with TP53 abnormalities. In-depth analysis of a subset of 39 DAWTs showed seven (18%) to be TP53-wt: These demonstrated gene expression evidence of an active p53 pathway. Retrospective pathology review of TP53-wt DAWT revealed no or very low volume of anaplasia in six of seven tumors. When samples from TP53-wt tumors known to contain anaplasia histologically were available, abnormal p53 protein accumulation was observed by immunohistochemistry. CONCLUSIONS: These data support the key role of TP53 loss in the development of anaplasia in WT, and support its significant clinical impact in patients with residual anaplastic tumor following surgery. These data also suggest that most DAWTs will show evidence of TP53 mutation when samples selected for the presence of anaplasia are analyzed. This suggests that modifications of the current criteria to also consider volume of anaplasia and documentation of TP53 aberrations may better reflect the risk of relapse and death and enable optimization of therapeutic stratification.

AB - A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether continuation of administration of preoperative aspirin until the day of coronary artery bypass grafting (CABG) could minimize postoperative mortality, prevalence of postoperative myocardial infarction (MI) with or without influence on postoperative bleeding, packed red blood cell (PRBC) transfusion and reoperation for bleeding. Altogether, 662 papers were found using the reported search, 7 of which represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Seven studies, included in this review, consisted of five meta-analyses and two randomized controlled trials. One meta-analysis, involving 27 533 patients submitted to CABG, showed that the administration of preoperative aspirin decreased postoperative 30-day mortality by 27%. Another meta-analysis, including 1437 patients, showed that preoperative aspirin decreased the incidence of perioperative MI by 44%, the effect being even more pronounced with low-dose aspirin, which reduced the prevalence of perioperative MI by 63%. One RCT showed that preoperative aspirin is associated with reduced long-term hazard of MI or repeated revascularization. Four meta-analyses and two RCTs showed that preoperative aspirin is associated with increased postoperative bleeding, PRBC transfusion and reoperation for bleeding. However, this was not the case with preoperative administration of low-dose aspirin. The results presented in these studies suggest that preoperative aspirin administration in patients undergoing CABG has a significant benefit in reducing the incidence of perioperative MI and 30-day mortality rate, as well as reduced long-term hazard of MI or repeated revascularization. At a higher dose (>100 mg/day), postoperative bleeding, PRBC transfusion and reoperation for bleeding increased. However, with low-dose aspirin (<=100 mg/day), these benefits were not at the expense of increased postoperative bleeding or transfusion. PMID- 27702831 TI - Reduction of INCOR(r) driveline infection rate with silicone at the driveline exit site. AB - Objectives: A silicone interface at skin level of left ventricular assist device (LVAD) may reduce the risk of driveline (DL) exit site infections when compared with other materials (e.g. velour). The purpose of this study was to evaluate the rate of DL exit site infection according to the presence of silicone or velour at the exit site with the redesigned INCOR, facilitating the positioning of silicone at the exit site. Methods: The rate of DL exit site infection and overall survival were compared between the two groups (silicone group, n = 16/velour group, n = 24) with 1-year follow-up postimplantation. Results: Risk factors for infection were more prevalent in the silicone group (obesity P = 0.33, prevalence of renal dysfunction P = 0.007, higher CRP levels P = 0.001). During the observation period, 6 patients developed a DL infection (25%) in the velour group, whereas 1 patient developed a DL infection in (6%) in the silicone group (P = 0.19). The event-per-patient year (EPPY) rates were 0.34 and 0.10 for velour group and silicone group, respectively (P = 0.30). All DL infections could be treated successfully by the antibiotic treatment, surgical debridement and ultimately high urgency heart transplantation, resulting in no direct DL infection-related mortality in this cohort. One-year survival was similar in both the groups (silicone 69 vs 75% in the velour group; P = 0.67). Conclusions: Fewer infections were observed at the exit site in case of a silicone-covered DL, without reaching statistical significance. More patients and longer observation periods are needed to demonstrate a statistical difference. PMID- 27702834 TI - Systolic Blood Pressure and Risk of Type 2 Diabetes: A Mendelian Randomization Study. AB - Observational studies have shown that elevated systolic blood pressure (SBP) is associated with future onset of type 2 diabetes, but whether this association is causal is not known. We applied the Mendelian randomization framework to evaluate the causal hypothesis that elevated SBP increases risk for type 2 diabetes. We used 28 genetic variants associated with SBP and evaluated their impact on type 2 diabetes using a European-centric meta-analysis comprising 37,293 case and 125,686 control subjects. We found that elevation of SBP levels by 1 mmHg due to our genetic score was associated with a 2% increase in risk of type 2 diabetes (odds ratio 1.02, 95% CI 1.01-1.03, P = 9.05 * 10-5). To limit confounding, we constructed a second score based on 13 variants exclusively associated with SBP and found a similar increase in type 2 diabetes risk per 1 mmHg of genetic elevation in SBP (odds ratio 1.02, 95% CI 1.01-1.03, P = 1.48 * 10-3). Sensitivity analyses using multiple, alternative causal inference measures and simulation studies demonstrated consistent association, suggesting robustness of our primary observation. In line with previous reports from observational studies, we found that genetically elevated SBP was associated with increased risk for type 2 diabetes. Further work will be required to elucidate the biological mechanism and translational implications. PMID- 27702835 TI - Comparative evaluation of three new commercial immunoassays for anti-Mullerian hormone measurement. AB - STUDY QUESTION: How do the three new anti-Mullerian hormone (AMH) assay methods, manufactured by Beckman Coulter, Roche and Ansh Labs compare with each other and with the Gen II assay? SUMMARY ANSWER: The three new AMH assays are well correlated among themselves and with the Gen II assay, although differences in calibration do exist. WHAT IS KNOWN ALREADY: The Gen II assay has been the mainstay method for AMH measurement in the past few years. Recently, a few new AMH measurement methods have come to the market. STUDY DESIGN, SIZE, DURATION: This was a prospective assay evaluation performed on 178 human serum samples. PARTICIPANTS/MATERIALS, SETTING, METHODS: AMH concentration was measured in residual serum samples donated by female patients in a reproductive medicine centre. The three new assay methods were tested in parallel and the numerical values obtained were compared among themselves and with those obtained by the Gen II assay. The assay stability upon different sample storage conditions, intra assay and inter-assay precision, linearity and dilution recovery, and diagnostic performance for polycystic ovary syndrome (PCOS) of the three new AMH assay methods were also compared. MAIN RESULTS AND THE ROLE OF CHANCE: AMH values measured by the Gen II kit and the three new assay methods have good correlations (R > 0.9 for all pairwise correlations). Values measured by the Ansh Labs assay were significantly higher, whereas those by the Roche assay were significantly lower, than those from the Gen II and Beckman-Coulter automated assays (P < 0.05). AMH values were significantly different when measured on the fresh and frozen-thawed serum sample (at -20oC and -80oC) for all three new methods (P < 0.05), but the magnitude of difference was very small with the Beckman-Coulter automated assay and Roche assay. The intra-assay coefficients of variation (CVs) were 0.7-2.2%, 0.5-1.4%, and 1.4-5.4% for the Beckman-Counter automated, Roche and Ansh Labs assays, respectively. Their inter-assay CVs were 0.9-2.5%, 0.7 1.9%, and 6.2-13.5%, respectively. All three new assay methods showed acceptable linearity, and provided excellent discrimination of PCOS from controls. LIMITATIONS, REASONS FOR CAUTION: The precision and dilution linearity experiments involved a small sample size, although these were not the primary outcome measures and have been properly evaluated in previous publications. The study was not designed or powered for determining diagnostic cut-off values. WIDER IMPLICATIONS OF THE FINDINGS: The results demonstrate that the three new AMH assay methods are all valid methods to be adopted in the field of reproduction and are a basis for further work on their clinical application. STUDY FUNDING/COMPETING INTERESTS: The authors have no competing interest to declare.

PMID- 27702832 TI - Impact of Perturbed Pancreatic beta-Cell Cholesterol Homeostasis on Adipose Tissue and Skeletal Muscle Metabolism. AB - Elevated pancreatic beta-cell cholesterol levels impair insulin secretion and reduce plasma insulin levels. This study establishes that low plasma insulin levels have a detrimental effect on two major insulin target tissues: adipose tissue and skeletal muscle. Mice with increased beta-cell cholesterol levels were generated by conditional deletion of the ATP-binding cassette transporters, ABCA1 and ABCG1, in beta-cells (beta-DKO mice). Insulin secretion was impaired in these mice under basal and high-glucose conditions, and glucose disposal was shifted from skeletal muscle to adipose tissue. The beta-DKO mice also had increased body fat and adipose tissue macrophage content, elevated plasma interleukin-6 and MCP 1 levels, and decreased skeletal muscle mass. They were not, however, insulin resistant. The adipose tissue expansion and reduced skeletal muscle mass, but not the systemic inflammation or increased adipose tissue macrophage content, were reversed when plasma insulin levels were normalized by insulin supplementation. These studies identify a mechanism by which perturbation of beta-cell cholesterol homeostasis and impaired insulin secretion increase adiposity, reduce skeletal muscle mass, and cause systemic inflammation. They further identify beta-cell dysfunction as a potential therapeutic target in people at increased risk of developing type 2 diabetes. PMID- 27702836 TI - The predictive value of 18F-FDG PET for pathological response of primary tumor in patients with esophageal cancer during or after neoadjuvant chemoradiotherapy: a meta-analysis. AB - OBJECTIVE: We want to review the value of 18-fluoro-deoxy-glucose positron emission tomography for response prediction of primary tumor in patients with esophageal cancer during or after neoadjuvant chemoradiotherapy. METHODS: Studies were searched in Pubmed, Embase and Cochrane Library with specific search strategy. The published articles were included according to the criteria established in advance. The included studies were divided into two groups according to the time of the repeat positron emission tomography: during (Group A) or after neoadjuvant chemoradiotherapy (Group B). The studies that performed the repeat positron emission tomography after neoadjuvant chemoradiotherapy were graded Quality Assessment of Diagnostic Accuracy Studies. The pooled sensitivity, specificity and diagnostic odds ratio were obtained for both groups on the basis of no-existing of threshold effect. RESULTS: Fifteen studies were included in the present study. The threshold effect did not exist in both groups. The pooled sensitivity, specificity and diagnostic odds ratio were 85%, 59%, 6.82 with 95% confidence interval 76-91%, 48-69%, 2.25-20.72 in Group A. The equivalent values were 67%, 69%, 6.34 with 95% confidence interval 60-73%, 63-74%, 2.08-19.34 in Group B. The pooled sensitivity was 90% in four studies that enrolled patients with esophageal squamous cell carcinoma merely in Group B. CONCLUSIONS: According to the present data, positron emission tomography should not be used routinely to guide treatment strategy in esophageal cancer patients. We speculated that positron emission tomography could be used as a tool to predict treatment response after neoadjuvant chemoradiotherapy in patients with esophageal squamous cell carcinoma.

AB - Sustained dysregulation of blood glucose (hyper- or hypoglycemia) associated with type 1 diabetes (T1D) has been linked to cognitive deficits and altered brain anatomy and connectivity. However, a significant gap remains with respect to how T1D affects spontaneous at-rest connectivity in young developing brains. Here, using a large multisite study, resting-state functional MRI data were examined in young children with T1D (n = 57; mean age = 7.88 years; 27 females) as compared with age-matched control subjects without diabetes (n = 26; mean age = 7.43 years; 14 females). Using both model-driven seed-based analysis and model-free independent component analysis and controlling for age, data acquisition site, and sex, converging results were obtained, suggesting increased connectivity in young children with T1D as compared with control subjects without diabetes. Further, increased connectivity in children with T1D was observed to be positively associated with cognitive functioning. The observed positive association of connectivity with cognitive functioning in T1D, without overall group differences in cognitive function, suggests a putative compensatory role of hyperintrinsic connectivity in the brain in children with this condition. Altogether, our study attempts to fill a critical gap in knowledge regarding how dysglycemia in T1D might affect the brain's intrinsic connectivity at very young ages. PMID- 27702837 TI - Role of multimodality therapy in cIIIA-N2 non-small cell lung cancer: perspective. AB - A number of promising new approaches for both local and systemic control of locally advanced non-small cell lung cancer have been examined in clinical trials, aimed at improving the patient survival. Development of better systemic therapies by adopting newer agents (such as epidermal growth factor receptor tyrosine kinase inhibitors and immune checkpoint inhibitors) from advanced non small cell lung cancer is mandatory. As for radiotherapy, adaptive radiotherapy and proton therapy are under investigation after the RTOG 0617 trial unexpectedly failed to show the efficacy of high-dose radiotherapy for Stage III disease. To date, no Phase III trial has clearly shown the benefit of adding surgery as a part of multimodality therapy for locally advanced non-small cell lung cancer. Such poor progress in the development of effective treatments for Stage III non small cell lung cancer is considered to be attributable to the existence of heterogeneities in the disease characteristics, including the biological and anatomic characteristics. Constant effort via well-designed and well-conducted clinical trials is needed to decipher the heterogeneity of Stage III non-small cell lung cancer. PMID- 27702838 TI - Growing Older With a Physical Disability: A Special Application of the Successful Aging Paradigm. AB - Objectives: In the United States, the average age of people living with early acquired physical disabilities is increasing. This cohort is said to be aging with disability and represents a unique population among older adults. Given recent policy efforts designed to merge aging and disability services, it is critical that models of "successful aging" include and are relevant to this population. However, many current definitions of successful aging emphasize avoidance of disability and high levels of physical function as necessary to well being. Method: In 9 focus groups, we examined perspectives of "successful aging" in 49 middle-aged and older individuals living with spinal cord injury, multiple sclerosis, muscular dystrophy, or postpolio syndrome. Transcripts were analyzed using a structured qualitative coding approach and Dedoose indexing software. Results: Participants ranged in age from 45 to 80 years (M = 62) and had lived with their disability diagnosis for an average of 21 years. Analysis revealed 4 primary themes of successful aging: resilience/adaptation, autonomy, social connectedness, and physical health (including access to general and specialty healthcare). Discussion: Results highlight the need for a nuanced application of the "successful aging" paradigm in this population. PMID- 27702839 TI - Information and Communication Technology Use Is Related to Higher Well-Being Among the Oldest-Old. AB - Objectives: Older adults often prioritize socially meaningful goals over informational goals. Thus, we predicted that using information and communication technology (ICT) in service of socially meaningful versus informational goals relates to higher well-being among the oldest-old. Method: We surveyed 445 adults aged 80+ (mean = 84, range = 80-93; 64% female; 26% non-White) online or via telephone. Participants reported motivations for ICT use (connect with others, learn new information) and rated their psychological and physical well-being (i.e., life satisfaction, loneliness, goal attainment, subjective health, functional limitations). We conducted regression and mediation analyses to test our hypothesis. Results: Participants used ICT more to connect with friends/family (M = 3.66, SD = 1.28) than to learn information (M = 2.61, SD = 1.44), p < .001. Overall, ICT use predicted higher well-being across outcomes, ps <= .008. Motivations for use differentially mediated these effects: Social motivations mediated the relationships between ICT use and psychological well being, whereas informational motivations mediated the relationships between ICT use and physical well-being. Discussion: Older adults aged 80+ use ICT less than other generations, but may have much to gain. Using social versus informational technologies may enhance multiple aspects of well-being in different ways during very late life. Highlighting such benefits may increase ICT adoption among the oldest-old. PMID- 27702840 TI - Instrumental- and Emotion-Focused Care Work During Physical Health Events: Comparing Gay, Lesbian, and Heterosexual Marriages. AB - Objectives: We consider emotion- and instrumental-focused care work and marital stress during significant physical health events in midlife gay, lesbian, and heterosexual marriages. Method: We employ the factorial method, an extension of the actor-partner interdependence model, to analyze survey data from 808 midlife gay, lesbian, and heterosexual spouses in 404 unions. Results: The amount of emotion- and instrumental-focused care work provided during physical health events, and the associations between care work and marital stress, depends on the gender of the respondent, gender of the spouse, and whether spouses are in a same sex or different-sex union. For example, in both same- and different-sex marriages, women report providing more emotion-focused care work during their own health event than do men, and respondents report more health-related marital stress when the patient is a woman. Discussion: Investigating how midlife same sex and different-sex spouses care for each other during a spouse's health event expands understandings of gendered aging experiences within marriage. Findings can elucidate health policies and clinical strategies that best support the health of men and women in same- and different-sex marriages. PMID- 27702841 TI - Regulation of Stomatal Defense by Air Relative Humidity. AB - It has long been observed that environmental conditions play crucial roles in modulating immunity and disease in plants and animals. For instance, many bacterial plant disease outbreaks occur after periods of high humidity and rain. A critical step in bacterial infection is entry into the plant interior through wounds and natural openings, such as stomata, which are adjustable microscopic pores in the epidermal tissue. Several studies have shown that stomatal closure is an integral part of the plant immune response to reduce pathogen invasion. In this study, we found that high humidity can effectively compromise Pseudomonas syringae-triggered stomatal closure in both Phaseolus vulgaris and Arabidopsis (Arabidopsis thaliana), which is accompanied by early up-regulation of the jasmonic acid (JA) pathway and simultaneous down-regulation of salicylic acid (SA) pathway in guard cells. Furthermore, SA-dependent response, but not JA dependent response, is faster in guard cells than in whole leaves, suggesting that the SA signaling in guard cells may be independent from other cell types. Thus, we conclude that high humidity, a well-known disease-promoting environmental condition, acts in part by suppressing stomatal defense and is linked to hormone signaling in guard cells. PMID- 27702844 TI - The Thiamine Biosynthesis Gene THI1 Promotes Nodule Growth and Seed Maturation. AB - Thiamine (vitamin B1) is essential for living organisms. Unlike animals, plants can synthesize thiamine. In Lotus japonicus, the expression of two thiamine biosynthesis genes, THI1 and THIC, was enhanced by inoculation with rhizobia but not by inoculation with arbuscular mycorrhizal fungi. THIC and THI2 (a THI1 paralog) were expressed in uninoculated leaves. THI2-knockdown plants and the transposon insertion mutant thiC had chlorotic leaves. This typical phenotype of thiamine deficiency was rescued by an exogenous supply of thiamine. In wild-type plants, THI1 was expressed mainly in roots and nodules, and the thi1 mutant had green leaves even in the absence of exogenous thiamine. THI1 was highly expressed in actively dividing cells of nodule primordia. The thi1 mutant had small nodules, and this phenotype was rescued by exogenous thiamine and by THI1 complementation. Exogenous thiamine increased nodule diameter, but the level of arbuscular mycorrhizal colonization was unaffected in the thi1 mutant or by exogenous thiamine. Expression of symbiotic marker genes was induced normally, implying that mainly nodule growth was delayed in the thi1 mutant. Furthermore, this mutant formed many immature seeds with reduced seed weight. These results indicate that thiamine biosynthesis mediated by THI1 enhances nodule enlargement and is required for seed development in L. japonicus. PMID- 27702843 TI - OsHAC1;1 and OsHAC1;2 Function as Arsenate Reductases and Regulate Arsenic Accumulation. AB - Rice is a major dietary source of the toxic metalloid arsenic (As). Reducing its accumulation in rice (Oryza sativa) grain is of critical importance to food safety. Rice roots take up arsenate and arsenite depending on the prevailing soil conditions. The first step of arsenate detoxification is its reduction to arsenite, but the enzyme(s) catalyzing this reaction in rice remains unknown. Here, we identify OsHAC1;1 and OsHAC1;2 as arsenate reductases in rice. OsHAC1;1 and OsHAC1;2 are able to complement an Escherichia coli mutant lacking the endogenous arsenate reductase and to reduce arsenate to arsenite. OsHAC1:1 and OsHAC1;2 are predominantly expressed in roots, with OsHAC1;1 being abundant in the epidermis, root hairs, and pericycle cells while OsHAC1;2 is abundant in the epidermis, outer layers of cortex, and endodermis cells. Expression of the two genes was induced by arsenate exposure. Knocking out OsHAC1;1 or OsHAC1;2 decreased the reduction of arsenate to arsenite in roots, reducing arsenite efflux to the external medium. Loss of arsenite efflux was also associated with increased As accumulation in shoots. Greater effects were observed in a double mutant of the two genes. In contrast, overexpression of either OsHAC1;1 or OsHAC1;2 increased arsenite efflux, reduced As accumulation, and enhanced arsenate tolerance. When grown under aerobic soil conditions, overexpression of either OsHAC1;1 or OsHAC1;2 also decreased As accumulation in rice grain, whereas grain As increased in the knockout mutants. We conclude that OsHAC1;1 and OsHAC1;2 are arsenate reductases that play an important role in restricting As accumulation in rice shoots and grain. PMID- 27702842 TI - Developmental Control and Plasticity of Fruit and Seed Dimorphism in Aethionema arabicum. AB - Understanding how plants cope with changing habitats is a timely and important topic in plant research. Phenotypic plasticity describes the capability of a genotype to produce different phenotypes when exposed to different environmental conditions. In contrast, the constant production of a set of distinct phenotypes by one genotype mediates bet hedging, a strategy that reduces the temporal variance in fitness at the expense of a lowered arithmetic mean fitness. Both phenomena are thought to represent important adaptation strategies to unstable environments. However, little is known about the underlying mechanisms of these phenomena, partly due to the lack of suitable model systems. We used phylogenetic and comparative analyses of fruit and seed anatomy, biomechanics, physiology, and environmental responses to study fruit and seed heteromorphism, a typical morphological basis of a bet-hedging strategy of plants, in the annual Brassicaceae species Aethionema arabicum Our results indicate that heteromorphism evolved twice within the Aethionemeae, including once for the monophyletic annual Aethionema clade. The dimorphism of Ae. arabicum is associated with several anatomic, biomechanical, gene expression, and physiological differences between the fruit and seed morphs. However, fruit ratios and numbers change in response to different environmental conditions. Therefore, the life-history strategy of Ae. arabicum appears to be a blend of bet hedging and plasticity. Together with the available genomic resources, our results pave the way to use this species in future studies intended to unravel the molecular control of heteromorphism and plasticity. PMID- 27702846 TI - Fluoxetine vs. placebo for the treatment of recurrent vasovagal syncope with anxiety sensitivity. AB - AIMS: The optimal medical therapy of patients with vasovagal syncope (VVS) remains controversial. Fluoxetine is effective against anxiety and panic disorders, while its use has shown promising results for VVS. Anxiety sensitivity is a personality trait observed in a considerable proportion of patients with VVS, associated with predisposition to anxiety and panic disorders. Our aim was to examine whether fluoxetine exerts beneficial effects regarding VVS prevention in the subset of patients with anxiety sensitivity. METHODS AND RESULTS: We assessed 106 patients with typical history of recurrent VVS, without other comorbidities, and a diagnostic, positive head-up tilt test. A psychiatric examination ruled out clinical psychiatric disease. Their psychological, stress related profile was assessed by the Anxiety Sensitivity Index (ASI) questionnaire, a 16-item questionnaire, assessing fear of anxiety-related sensations, previously studied in VVS. Patients scoring positive for ASI (n = 60, 57% of the population) were randomized in a 2:1 fashion to receive either 10-40 mg fluoxetine daily (n = 40) or placebo (n = 20), and were followed-up for 1 year. A significant difference was observed between patients receiving fluoxetine and those with placebo, regarding the distribution of syncope-free time during the study (P < 0.05). A significant difference was also observed between the two groups regarding presyncopal events and the total number of patients who experienced syncope or presyncope during follow-up. CONCLUSION: Sensitivity to anxiety is a common personality trait in recurrent VVS. Fluoxetine is superior to placebo against syncope in these patients. This drug may be a first-line pharmacological treatment for this difficult-to-treat group. PMID- 27702845 TI - Phytoglobins Improve Hypoxic Root Growth by Alleviating Apical Meristem Cell Death. AB - Hypoxic root growth in maize (Zea mays) is influenced by the expression of phytoglobins (ZmPgbs). Relative to the wild type, suppression of ZmPgb1.1 or ZmPgb1.2 inhibits the growth of roots exposed to 4% oxygen, causing structural abnormalities in the root apical meristems. These effects were accompanied by increasing levels of reactive oxygen species (ROS), possibly through the transcriptional induction of four Respiratory Burst Oxidase Homologs TUNEL positive nuclei in meristematic cells indicated the involvement of programmed cell death (PCD) in the process. These cells also accumulated nitric oxide and stained heavily for ethylene biosynthetic transcripts. A sharp increase in the expression level of several 1-aminocyclopropane synthase (ZmAcs2, ZmAcs6, and ZmAcs7), 1-aminocyclopropane oxidase (Aco15, Aco20, Aco31, and Aco35), and ethylene-responsive (ZmErf2 and ZmEbf1) genes was observed in hypoxic ZmPgb suppressing roots, which overproduced ethylene. Inhibiting ROS synthesis with diphenyleneiodonium or ethylene perception with 1-methylcyclopropene suppressed PCD, increased BAX inhibitor-1, an effective attenuator of the death programs in eukaryotes, and restored root growth. Hypoxic roots overexpressing ZmPgbs had the lowest level of ethylene and showed a reduction in ROS staining and TUNEL positive nuclei in the meristematic cells. These roots retained functional meristems and exhibited the highest growth performance when subjected to hypoxic conditions. Collectively, these results suggest a novel function of Pgbs in protecting root apical meristems from hypoxia-induced PCD through mechanisms initiated by nitric oxide and mediated by ethylene via ROS. PMID- 27702847 TI - Termination of persistent atrial fibrillation during pulmonary vein isolation: insight from the MAGIC-AF trial. AB - Aims: Controversy on the optimal ablation strategy for persistent atrial fibrillation (AF) exists with limited work evaluating a strategy of pulmonary vein isolation (PVI) alone when AF terminates during PVI. Thirty-five patients had AF termination during PVI in the Modified Ablation Guided by Ibutilide Use in Chronic Atrial Fibrillation (MAGIC-AF; ClinicalTrials.gov number: NCT01014741) study. The objective of the current study is to report the 1-year outcome after PVI alone in this unique patient group. Methods and results: The 1-year single procedure freedom from atrial arrhythmia off anti-arrhythmic drugs was reported for the 35 patients in the MAGIC-AF study with persistent AF termination during or upon completion of PVI. Freedom from recurrent atrial arrhythmia was achieved in 60% of patients where AF terminated during PVI. Cavotricuspid isthmus flutter was common when AF terminated to a macro re-entrant flutter during PVI, and responsible for 92% of all flutter circuits with AF termination. Conclusions: Persistent AF termination during PVI may identify a subgroup of patients who experience a similar long-term clinical outcome with PVI ablation alone when compared with other more extensive persistent AF ablation strategies. Pulmonary vein isolation alone may be an appropriate tactic in this subgroup of persistent AF patients. PMID- 27702849 TI - Time matters: adenosine testing immediately after pulmonary vein isolation does not substitute a waiting period. AB - Aims: Adenosine testing can reveal dormant pulmonary vein (PV) conduction after PV antrum isolation (PVAI). However, the optimal timing for adenosine administration is unknown. We hypothesized that adenosine testing immediately after PVAI reliably reveals PV reconnection and thereby eliminates the need for an observation period. Methods and results: Fifty patients underwent PVAI. Immediately after isolation of a PV pair, adenosine was administered. Both PV pairs were separately tested. If adenosine restored PV conduction, PVs were re isolated. During a >=30 min observation period after immediate adenosine-guided isolation, spontaneous reconnection was assessed and reconnected PVs were re isolated. After the observation period, adenosine testing was repeated. Immediate adenosine testing revealed dormant conduction in 10.4% of the left PVs and 16.3% of the right PVs. All PVs were successfully re-isolated. During a mean observation period of 36 +/- 10 min, spontaneous reconnection occurred in 8.2% of the left and 16.3% of the right PVs. None of these PVs had shown reconnection during immediate testing. Late adenosine testing revealed dormant conduction in 12.5% of the left and 16.3% of the right PVs. In patients without reconnection during immediate adenosine testing, 14.6% of the left PVs and 30.6% of the right PVs showed either spontaneous reconnection or restored PV conduction during late adenosine testing. Conclusion: Adenosine testing immediately after PVAI does not reliably exclude later spontaneous or adenosine-induced PV reconnection. Adenosine testing should be performed after an appropriate observation period to reduce risk of PV reconnection. PMID- 27702848 TI - Contemporary rates and outcomes of single- vs. dual-coil implantable cardioverter defibrillator lead implantation: data from the Israeli ICD Registry. AB - Aims: Dual-coil leads were traditionally considered standard of care due to lower defibrillation thresholds (DFT). Higher complication rates during extraction with parallel progression in implantable cardioverter defibrillator (ICD) technology raised questions on dual coil necessity. Prior substudies found no significant outcome difference between dual and single coils, although using higher rates of DFT testing then currently practiced. We evaluated the temporal trends in implantation rates of single- vs. dual-coil leads and determined the associated adverse clinical outcomes, using a contemporary nation-wide ICD registry. Methods and results: Between July 2010 and March 2015, 6343 consecutive ICD (n = 3998) or CRT-D (n = 2345) implantation patients were prospectively enrolled in the Israeli ICD Registry. A follow-up of at least 1 year of 2285 patients was available for outcome analysis. The primary endpoint was all-cause mortality. Single-coil leads were implanted in 32% of our cohort, 36% among ICD recipients, and 26% among CRT D recipients. Secondary prevention indication was associated with an increased rate of dual-coil implantation. A significant decline in dual-coil leads with reciprocal incline of single coils was observed, despite low rates of DFT testing (11.6%) during implantation, which also declined from 31 to 2%. In the multivariate Cox model analysis, dual- vs. single-coil lead implantation was not associated with an increased risk of mortality [hazard ratio (HR) = 1.23; P= 0.33], heart failure hospitalization (HR = 1.34; P=0.13), appropriate (HR = 1.25; P= 0.33), or inappropriate ICD therapy (HR = 2.07; P= 0.12). Conclusion: Real life rates of single-coil lead implantation are rising while adding no additional risk. These results of single-coil safety are reassuring and obtained, despite low and contemporary rates of DFT testing. PMID- 27702850 TI - Traditional and novel electrocardiographic conduction and repolarization markers of sudden cardiac death. AB - Sudden cardiac death, frequently due to ventricular arrhythmias, is a significant problem globally. Most affected individuals do not arrive at hospital in time for medical treatment. Therefore, there is an urgent need to identify the most-at risk patients for insertion of prophylactic implantable cardioverter defibrillators. Clinical risk markers derived from electrocardiography are important for this purpose. They can be based on repolarization, including corrected QT (QTc) interval, QT dispersion (QTD), interval from the peak to the end of the T-wave (Tpeak - Tend), (Tpeak - Tend)/QT, T-wave alternans (TWA), and microvolt TWA. Abnormal repolarization properties can increase the risk of triggered activity and re-entrant arrhythmias. Other risk markers are based solely on conduction, such as QRS duration (QRSd), which is a surrogate marker of conduction velocity (CV) and QRS dispersion (QRSD) reflecting CV dispersion. Conduction abnormalities in the form of reduced CV, unidirectional block, together with a functional or a structural obstacle, are conditions required for circus-type or spiral wave re-entry. Conduction and repolarization can be represented by a single parameter, excitation wavelength (lambda = CV * effective refractory period). lambda is an important determinant of arrhythmogenesis in different settings. Novel conduction-repolarization markers incorporating lambda include Lu et al.' index of cardiac electrophysiological balance (iCEB: QT/QRSd), [QRSD* (Tpeak - Tend)/QRSd] and [QRSD * (Tpeak - Tend)/(QRSd * QT)] recently proposed by Tse and Yan. The aim of this review is to provide up to date information on traditional and novel markers and discuss their utility and downfalls for risk stratification. PMID- 27702851 TI - The wearable cardioverter-defibrillator: current technology and evolving indications. AB - The wearable cardioverter-defibrillator has been available for over a decade and now is frequently prescribed for patients deemed at high arrhythmic risk in whom the underlying pathology is potentially reversible or who are awaiting an implantable cardioverter-defibrillator. The use of the wearable cardioverter defibrillator is included in the new 2015 ESC guidelines for the management of ventricular arrhythmias and prevention of sudden cardiac death. The present review provides insight into the current technology and an overview of this approach. PMID- 27702853 TI - Left atrial model reconstruction in atrial fibrillation ablation: reliability of new mapping and complex impedance systems. AB - Aims: The effectiveness of atrial fibrillation (AF) ablation relies on detailed knowledge of the anatomy of the left atrium (LA) and pulmonary veins (PVs). It is common to combine computed tomography/magnetic resonance (CT/MR) with imaging by electroanatomical (EA) mapping systems. The aim of this study was to evaluate the accuracy of LA anatomical reconstruction by 'One Model' and 'VeriSense' tools (Ensite Velocity 3.0, St Jude Medical), compared with CT/MR imaging. Methods and results: Seventy-two patients with AF underwent pre-procedural imaging (97% CT scan, 3% MR imaging) and transcatheter ablation of PVs. Operators were blinded to CT/MR imaging. Electrical Coupling Index (ECI) was used to recognize venous structures when the circular catheter could not. The LA 'One Model' map was obtained without complications; all 124 main left PVs and 144 main right PVs were detected. Nine of 9 intermediate right PVs and 30 of 30 early branches were detected, whereas 1 of the 27 early branches on the right inferior PVs was missed. Comparison between LA intervein distances measured on the roof (RO) and the posterior wall (PW) showed a high correspondence between the EA model and CT/MR imaging (RO CT/MR imaging vs. EA: 32 +/- 7 vs. 32 +/- 7 mm; PW CT/MR imaging vs. EA: 36 +/- 6 vs. 36 +/- 7 mm). The EA model yielded slightly larger PV ostia diameters, owing to the distortion caused by catheter pressure. Conclusions: Recent 3D mapping tools allow outstanding anatomical rendering and are key in complex ablation procedure set-up. This study shows that 3D anatomical reconstruction of LA, PVs, and their variable branches is not only safe and fast but also accurate and reliable. PMID- 27702852 TI - Antiadrenergic autoimmunity in postural tachycardia syndrome. AB - Aims: Postural tachycardia syndrome (POTS), a common and debilitating cardiovascular disorder, is characterized by an exaggerated heart rate increase during orthostasis and a wide spectrum of adrenergic-related symptoms. To determine the aetiology of POTS, we examined a possible pathophysiological role for autoantibodies against alpha1-adrenergic (alpha1AR) and beta1/2-adrenergic receptors (beta1/2AR). Methods and results: Immunoglobulin G (IgG) derived from 17 POTS patients, 7 with recurrent vasovagal syncope (VVS), and 11 normal controls was analysed for its ability to modulate activity and ligand responsiveness of alpha1AR and beta1/2AR in transfected cells and to alter contractility of isolated rat cremaster arterioles in vitro. Immunoglobulin G activation of alpha1AR and beta1/2AR was significantly higher in POTS compared with VVS and controls in cell-based assays. Eight, 11, and 12 of the 17 POTS patients possessed autoantibodies that activated alpha1AR, beta1AR and beta2AR, respectively. Pharmacological blockade suppressed IgG-induced activation of alpha1AR and beta1/2AR. Eight of 17 POTS IgG decreased the alpha1AR responsiveness to phenylephrine and 13 of 17 POTS IgG increased the beta1AR responsiveness to isoproterenol irrespective of their ability to directly activate their receptors. Postural tachycardia syndrome IgG contracted rat cremaster arterioles, which was reversed by alpha1AR blockade. The upright heart rate correlated with IgG-mediated beta1AR and alpha1AR activity but not with beta2AR activity. Conclusion: These data confirm a strong relationship between adrenergic autoantibodies and POTS. They support the concept that allosteric mediated shifts in the alpha1AR and beta1AR responsiveness are important in the pathophysiology of postural tachycardia. PMID- 27702854 TI - Incidence of silent cerebral infarctions after catheter ablation of atrial fibrillation utilizing the second-generation cryoballoon. AB - Aims: Pulmonary vein (PV) isolation (PVI) utilizing a cryoballoon (CB) has become one of the standard therapeutic options for atrial fibrillation (AF). However, it connotes a potential risk of cerebral ischaemic events (CIEs). This study aimed to clarify the prevalence of CIEs after PVI using second-generation CBs assessed by magnetic resonance imaging (MRI) of the brain. Methods and results: This prospective observational study consisted of 160 patients that underwent PVI with second-generation CBs for drug-refractory AF. Irrigated radiofrequency (RF) ablation for 'touch-up' procedures was utilized when conduction gaps between the left atrium (LA) and PVs were found after the CB application. Radiofrequency linear ablation was added in select patients. Cerebral MRI and neurological examinations were performed on the day following the ablation procedure. The MRI depicted micro-cerebral infarctions in 43 patients (26.9%, 1.49 lesions per case). All patients were free from symptomatic focal neurological deficits. Touch up ablation was required for the PVI establishment in 35 patients (21.9%). Linear ablation was performed in 59 patients (36.9%). Additional RF ablation within the LA was an independent risk of CIEs in the uni- and multivariate analyses. When the analyses were limited to patients who had undergone only CB ablation, CIEs were found in 12 of 66 patients (18.2%). Conclusion: Pulmonary vein isolation utilizing second-generation CBs carries a negligible risk of symptomatic CIEs; however, it includes a comparable risk of asymptomatic CIEs as in the previous similar reports using the first-generation CB. Radiofrequency applications in addition to the CB within the LA were the only predictor of this adverse effect. PMID- 27702855 TI - Simultaneous display of multiple three-dimensional electrophysiological datasets (dot mapping). AB - Aims: Complex ablation procedures are supported by accurate representation of an increasing variety of electrophysiological and imaging data within electroanatomic mapping systems (EMS). This study aims to develop a novel method for representing multiple complementary datasets on a single cardiac chamber model. Validation of the system and its application to both atrial and ventricular arrhythmias is examined. Methods and results: Dot mapping was conceived to display multiple datasets by utilizing quantitative surface shading to represent one dataset and finely spaced dots to represent others. Dot positions are randomized within triangular (surface meshes) or tetrahedral (volumetric meshes) simplices making the approach directly transferrable to contemporary EMS. Test data representing uniform electrical activation (n = 10) and focal scarring (n = 10) were used to test dot mapping data perception accuracy. User experience of dot mapping with atrial and ventricular clinical data is evaluated. Dot mapping ensured constant screen dot density for regions of uniform dataset values, regardless of user manipulation of the cardiac chamber. Perception accuracy of dot mapping was equivalent to colour mapping for both propagation direction (1.5 +/- 1.8 vs. 4.8 +/- 5.3 degrees , P = 0.24) and focal source localization (1.1 +/- 0.7 vs. 1.4 +/- 0.5 mm, P = 0.88). User acceptance testing revealed equivalent diagnostic accuracy and display fidelity when compared with colour mapping. Conclusion: Dot mapping provides the unique ability to display multiple datasets from multiple sources on a single cardiac chamber model. The visual combination of multiple datasets may facilitate interpretation of complex electrophysiological and imaging data. PMID- 27702856 TI - Atrial arrhythmia after transcatheter closure of secundum atrial septal defects in patients >=40 years of age. AB - Aim: Data on arrhythmia outcome following device closure of atrial septal defect (ASD) are lacking. This study provides medium-term follow-up data on atrial arrhythmias in patients who were >=40 years of age at the time of transcatheter ASD closure. Methods and results: It is a retrospective review. Mean age of the 159 patients was 57 years. Median follow-up was 3.6 years (range 6 months-10.9 years). Patients were classified, according to arrhythmia status prior to ASD closure, into Group I, no history of atrial arrhythmia (n = 119, mean age 55.5 years); Group II, paroxysmal atrial arrhythmia (n = 18, mean age 55.7 years); and Group III, persistent atrial fibrillation (n = 22, mean age 65.7 years). Group III patients were significantly older, had larger left atrial size, and had higher mean pulmonary arterial pressure than Group I and II patients (P < 0.001). Prior to closure, radiofrequency ablation was carried out in 12/18 (66%) of Group II and 3/22 (14%) of Group III. After device closure, 7 patients (6%) of Group I developed new atrial fibrillation. Fifty per cent (9/18) of Group II but only 9% (2/22) of Group III were in sinus rhythm on follow-up. Conclusion: Device closure alone in patients with persistent atrial arrhythmia is not likely to restore sinus rhythm in the medium term. New atrial arrhythmia occurred in 6% of patients who were in sinus rhythm prior to device closure. At least 50% of the patients with paroxysmal atrial arrhythmia continue to have significant atrial arrhythmia following device closure, and the role of ablation prior to closure in patients with a history of arrhythmia requires refinement. PMID- 27702859 TI - Antiarrhythmic effect of vernakalant in an experimental model of Long-QT syndrome. AB - Aims: The antiarrhythmic drug vernakalant exerts antiarrhythmic effects in atrial fibrillation. Recent experimental data suggest interactions with the late sodium current and antiarrhythmic effects in ventricular arrhythmias. We aimed at investigating whether treatment with vernakalant reduces polymorphic ventricular tachycardia (VT) in an experimental model of Long-QT-syndrome (LQTS). Methods and results: Twenty-nine isolated rabbit hearts were assigned to two groups and treated with erythromycin (300 uM, n = 15) or veratridine (0.5 uM, n = 14) after obtaining baseline data. Thereafter, vernakalant (10 uM) was additionally infused. Infusion of erythromycin or veratridine significantly increased action potential duration (APD90) and QT interval. Erythromycin and veratridine also significantly augmented spatial dispersion of repolarization (erythromycin: +43 ms; veratridine: +55 ms, P < 0.01, respectively) and temporal dispersion of repolarization. After lowering extracellular [K+] in bradycardic hearts, 11 of 15 erythromycin-treated hearts and 4 of 14 veratridine-treated hearts showed early afterdepolarizations and subsequent polymorphic VT. Additional treatment with vernakalant resulted in a significant reduction of spatial dispersion of spatial dispersion in both groups (erythromycin: -32 ms; veratridine: -35 ms, P < 0.05 each) and a stabilization of temporal dispersion. After additional treatment with vernakalant, only 5 of 15 erythromycin-treated hearts (P = 0.07) and 1 of 14 veratridine-treated hearts (P = 0.32) presented polymorphic VT. Conclusion: Vernakalant has antiarrhythmic effects in this experimental model of acquired LQTS. A reduction of spatial dispersion of repolarization and a stabilization of temporal dispersion in hearts showing polymorphic VT represent the major underlying electrophysiological mechanisms. PMID- 27702858 TI - Reduction of falls and fractures after permanent pacemaker implantation in elderly patients with sinus node dysfunction. AB - Aims: Elderly patients with sinus node dysfunction (SND) are at increased risk of falls with possible injuries. However, the incidence of these adverse events and its reduction after permanent pacemaker (PPM) implantation are not known. Methods and results: Eighty-seven patients (mean [SD] age 75.4 [8.3] years, 51% women) with SND and an indication for cardiac pacing were included and were examined by a standardized interview targeting fall history. The incidence and total number of falls, falls with injury, falls requiring treatment, and falls resulting in a fracture were assessed for the time period of 12 months before (retrospectively) and after PPM implantation (prospectively). Furthermore, symptoms such as syncope, dizziness, and dyspnea were evaluated before and after PPM implantation. The implantation of a PPM was associated with a reduced proportion of patients experiencing at least one fall by 71% (from 53 to 15%, P < 0.001) and a reduction of the absolute number of falls by 90% (from 127 to 13, P < 0.001) during the 12 months before vs. after PPM implant. Falls with injury (28 vs. 10%, P = 0.005), falls requiring medical attention (31 vs. 8%, P < 0.001), and falls leading to fracture (8 vs. 0%, P = 0.013) were similarly reduced. Notably, fewer patients had syncope (4 vs. 45%, P < 0.001) and dizziness after PPM implantation (12 vs. 45%, P < 0.001). Conclusion: Falls, fall-related injuries, and fall-related fractures are frequent in SND patients. Permanent pacemaker implantation is associated with a significantly reduced risk of these adverse events, although no causal relationship could be established due to the study design. PMID- 27702860 TI - Frequent atrial extrasystolic beats predict atrial fibrillation in patients with congenital heart defects. AB - Aims: Atrial fibrillation (AF) is increasingly observed in patients with congenital heart defects (CHDs) who survive nowadays into adulthood. Yet, predictors of AF are scarce in this high-risk population. This study therefore examined the predictive ability of atrial extrasystole (AES) for development of AF in CHD patients. Methods and results: Adult CHD patients who had a 24 h Holter registration were followed to determine who developed AF. A total of 573 patients (49% male, mean age 35 +/- 12 years) were included; they had a simple/complete repaired CHD (n = 279), complex repaired CHD (n = 251), or univentricular heart (UVH, n = 43). Ageing (P < 0.0001), female gender (P = 0.028), UVH (P = 0.0010), and left atrial dilatation (P = 0.0025) were associated with the number of AES. During a median follow-up of 51.6 months (interquartile range 22.8-85.7), 29 patients (5%) developed de novo AF. An one-point increase in the number of logtotal-AES was associated with a two-fold higher risk of AF development (hazard ratio 1.95; 95% confidence interval 1.21-3.13; P = 0.016). C-statistic for left atrial dilatation, complexity, and age had a good discriminative ability for the incidence of AF with a C-statistic of 84.5%. The addition of the total number of AES/24 h to this model increased C-statistic to 88.4%. Conclusion: Atrial extrasystole occur relatively frequent in adult CHD patients compared with patients with other cardiac diseases. This is the first study that showed an association between an increased AES frequency and a higher risk of AF development in CHD patients. PMID- 27702863 TI - The slope of the initial temperature drop predicts acute pulmonary vein isolation using the second-generation cryoballoon. AB - Aims: There is no objective, early indicator of occlusion quality, and efficacy of cryoballoon pulmonary vein isolation. As previous experience suggests that the initial cooling rate correlates with these parameters, we investigated the slope of the initial temperature drop as an objective measure. Methods and results: A systematic evaluation of 523 cryoapplications in 105 patients using a serial ROC AUC analysis was performed. We found the slope of a linear regression of the temperature-time function to be a good predictor (PPV 0.9, specificity 0.72, sensitivity 0.71, and ROC-AUC 0.75) of acute isolation. It also correlated with nadir temperatures (P< 0.001, adjusted R2= 0.43), predicted very low nadir temperatures, and varied according to visual occlusion grades (ANOVA P< 0.001). Conclusions: About 25 s after freeze initiation, the temperature-time slope predicts important key characteristics of a cryoablation, such as nadir temperature. The slope is the only reported predictor to actually precede acute isolation and thus to support decisions about pull-down manoeuvres or aborting a cryoablation early on. It is also predictive of very low nadir temperatures and phrenic nerve palsy and thus may add to patient safety. PMID- 27702861 TI - The economic impact of battery longevity in implantable cardioverter defibrillators for cardiac resynchronization therapy: the hospital and healthcare system perspectives. AB - Aims: Patients receiving cardiac resynchronization therapy defibrillators (CRT Ds) are likely to undergo one or more device replacements, mainly for battery depletion. We assessed the economic impact of battery depletion on the overall cost of CRT-D treatment from the perspectives of the healthcare system and the hospital. We also compared devices of different generations and from different manufacturers in terms of therapy cost. Methods and results: We analysed data on 1792 CRT-Ds implanted in 1399 patients in 9 Italian centres. We calculated the replacement probability and the total therapy cost over 6 years, stratified by device generation and manufacturer. Public tariffs from diagnosis-related groups were used together with device prices and hospitalization costs. Generators were from 3 manufacturers: Boston Scientific (667, 37%), Medtronic (973, 54%), and St Jude Medical (152, 9%). The replacement probability at 6 years was 83 and 68% for earlier- and recent-generation devices, respectively. The need for replacement increased total therapy costs by more than 50% over the initial implantation cost for hospitals and by more than 30% for healthcare system. The improved longevity of recent-generation CRT-Ds reduced the therapy cost by ~6% in both perspectives. Among recent-generation CRT-Ds, the replacement probability of devices from different manufacturers ranged from 12 to 70%. Consequently, the maximum difference in therapy cost between manufacturers was 40% for hospitals and 19% for the healthcare system. Conclusions: Differences in CRT-D longevity strongly affect the overall therapy cost. While the use of recent-generation devices has reduced the cost, significant differences exist among currently available systems. PMID- 27702864 TI - Cryoballoon vs. radiofrequency ablation for paroxysmal atrial fibrillation: an updated meta-analysis of randomized and observational studies. AB - Aims: Radiofrequency (RF) ablation represents a standard of care for pulmonary vein isolation in patients with drug-refractory paroxysmal atrial fibrillation (AF). In this setting, cryoballoon (CB) ablation has emerged as alternative therapy. However, the efficacy and safety of CB vs. RF ablation in patients with paroxysmal AF remain a matter of debate. Methods and results: We searched electronic scientific databases for studies of CB vs. RF ablation in patients with paroxysmal AF. Aggregate data were pooled to perform a meta-analysis. The primary efficacy and safety outcomes were the recurrence of any atrial arrhythmia and procedure-related complications, respectively. A total of 6473 participants from 10 studies (CB, n = 2232 vs. RF, n = 4241) were studied. After a median follow-up of 16 months, the risk of any atrial arrhythmia recurrence (risk ratio, RR 95% confidence interval [95% CI] = 1.01 [0.90-1.14], P = 0.83) and procedure related complications (RR [95% CI] = 0.92 [0.66-1.28], P = 0.61) were comparable between CB vs. RF ablation. Cryoballoon ablation led to a higher risk of persistent phrenic nerve palsy (RR [95% CI] = 13.60 [3.87-47.81], P < 0.01) and a lower risk of cardiac tamponade (RR [95% CI] = 0.48 [0.25-0.89], P = 0.02) compared with RF ablation. There was a trend of statistically significant interaction between the type of CB and the duration of ablation (P for interaction = 0.09). Conclusion: In patients with paroxysmal AF, ablation therapy with CB is associated with efficacy and safety comparable to that of RF. Second generation CB catheters seem to reduce procedure duration. Further studies are warranted to disclose the impact of second-generation CB catheters compared with RF for ablation of paroxysmal AF. PMID- 27702865 TI - Atrial fibrillation detection using a novel three-vector cardiac implantable monitor: the atrial fibrillation detect study. AB - Aims: Continuous rhythm monitoring is valuable for adequate atrial fibrillation (AF) management in the clinical setting. Subcutaneous leadless implantable cardiac monitors (ICMs) yield an improved AF detection, overcoming the intrinsic limitations of the currently available external recording systems, thus resulting in a more accurate patient treatment. The study purpose was to assess the detection performance of a novel three-vector ICM device equipped with a dedicated AF algorithm. Methods and results: Sixty-six patients (86.4% males; mean age 60.4 +/- 9.4 years) at risk to present AF episodes, having undergone the novel ICM implant (BioMonitor, Biotronik SE&Co. KG, Berlin, Germany), were enrolled. External 48-h ECG Holter was performed 4 weeks after the device implantation. The automatic ICM AF classification was compared with the manual Holter arrhythmia recordings. Of the overall study population, 63/66 (95.5%) had analysable Holter data, 39/63 (62%) showed at least one true AF episode. All these patients had at least one AF episode stored in the ICM. On Holter monitoring, 24/63 (38%) patients did not show AF episodes, in 16 of them (16/24, 67%), the ICM confirmed the absence of AF. The AF detection sensitivity and positive predictive value for episodes' analysis were 95.4 and 76.3%, respectively. Conclusion: Continuous monitoring using this novel device, equipped with a dedicated detection algorithm, yields an accurate and reliable detection of AF episodes. The ICM is a promising tool for tailoring individual AF patient management. Further long-term prospective studies are necessary to confirm these encouraging results. PMID- 27702866 TI - Safety and efficacy of applying a low-dose radiation fluoroscopy protocol in device implantations. AB - Aims: For cardiac implantable electronic device (CIED) implantations, visualization of lead placement is necessary and fluoroscopy remains by far the most commonly used technique. With simple changes in the X-ray system settings, total radiation dose can be reduced significantly. The purpose of this study was to assess the safety and efficacy of various CIED implantations performed after implementation of a new dose reduction protocol (DRP). Methods and results: We conducted a retrospective chart review of 584 patients undergoing CIED implantation or revision in our hospital. Of these patients, 280 (48%) underwent the implantation prior to and 304 (52%) after the DRP introduction. The DRP included various changes for optimized image processing and exposure system settings to enable dose reduction, as well as a reduced frame rates (4 FPS for fluoroscopy and 7.5 FPS for cinematographic images). Of the 584 patients, 53 (9.1%) had a one-chamber pacemaker, 232 (39.7%) a two-chamber pacemaker, 133 (22.8%) a one-chamber ICD, 35 (6.0%) a two-chamber ICD, 82 (14.0%) a CRT (de novo) implantation, and 49 (8.3%) had an upgrade to a CRT device. DRP was associated with a 64% reduction of the dose-area product (1372 +/- 2659 vs. 3792 +/- 5025 cGcm2, P < 0.001), while fluoroscopy duration (13 +/- 15 vs. 13 +/- 15 min) and procedural duration (93 +/- 52 vs. 92 +/- 52 min.) did not significantly increase. Complication rates did not differ significantly between the two groups. Conclusion: The DRP proved to effectively reduce radiation dose for all types of CIED implantations. Fluoroscopy time, total procedure time, and the number of complications did not increase after introducing the DRP. PMID- 27702867 TI - Patterns of physical activity and survival following cardiac resynchronization therapy implantation: the ALTITUDE activity study. AB - Aims: Cardiac resynchronization therapy with implantable defibrillator backup (CRT-D) improves outcomes, but predictors and markers of response remain limited. Physical activity information collected by CRT devices may provide insights to CRT response and the relationship between activity changes and survival. Methods and results: Patients entered into the LATITUDE remote monitoring system from 2008 to 2012 after receipt of a new CRT-D were eligible. Mean daily activity was calculated from LATITUDE uploads at baseline (first 3-10 days following implant) and 6 months (180-210 days). Pairwise differences for baseline-6-month activity were calculated, and survival according to quintiles of 6-month activity change was assessed. Cox regression was used to examine the adjusted association between survival and baseline-6-month activity change. A total of 26 509 patients were followed for a median of 2.3 years (mean age 70.2 +/- 11.0 years, 70.7% male). Mean baseline activity was 66.2 +/- 47.7 min/day, with mean paired increase at 6 months of 37.1 +/- 48.2 min/day [95% CI (confidence interval), 36.5-37.6, P < 0.0001], though 15.5% of patients did not improve or worsened at 6 months. Survival at 3 years was significantly higher in the largest baseline-6-month activity change quintile vs. the lowest quintile (88.9% vs. 62.1%, log-rank P value < 0.001). Adjusted for age and gender, higher 6-month activity change was associated with a lower risk of death (adjusted hazard ratios 0.65 per 30 min increase in activity, 95% CI, 0.63-0.67). Conclusions: Change in physical activity between baseline and 6 months following CRT implantation is strongly associated with survival. PMID- 27702870 TI - Initial clinical results with the ThermoCool(r) SmartTouch(r) Surround Flow catheter. AB - Aim: The Biosense Webster ThermoCool(r) SmartTouch(r) Surround Flow (STSF) catheter is a recently developed ablation catheter incorporating Surround Flow (SF) technology to ensure efficient cooling and force sensing to quantify tissue contact. In our unit, it superseded the ThermoCool(r) SF catheter from the time of its introduction in May 2015. Methods and results: Procedure-related data were collected prospectively for the first 100 ablation procedures performed in our department using the STSF catheter. From a database of 654 procedures performed in our unit using the SF catheter, we selected one to match each STSF procedure, matching for procedure type, operator experience, patient age, and gender. The groups were well matched for patient age, gender, and procedure type. Procedure duration was similar in both groups (mean 225.5 vs. 221.4 min, IQR 106.5 vs. 91.5, P = 0.55), but fluoroscopy duration was shorter in the STSF group (mean 25.8 vs. 30.0, IQR 19.6 vs. 18.5, P = 0.03). No complication occurred in the STSF group. Complications occurred in two cases in the SF group (one pericardial effusion requiring drainage and one need for permanent pacing). Complete procedural success was achieved in 98 cases in the STSF group and 94 cases in the SF group (P = 0.15). The composite endpoint of procedure failure or acute complication was less common in the STSF group (2 vs. 8, P = 0.05). Conclusion: The STSF catheter is safe and effective in treating a range of arrhythmias. Compared with the SF catheter, it shows a trend towards improved safety-efficacy balance. PMID- 27702869 TI - Electrophysiological features and catheter ablation of symptomatic frequent premature atrial contractions. AB - Aims: Frequent premature atrial contractions (PACs) are associated with increased risk of atrial fibrillation (AF), stroke, and death. This study aimed to explore the electrophysiological features of PACs with and without inducing AF and to evaluate the effectiveness of catheter ablation for PACs. Methods and results: Thirty-five consecutive patients with symptomatic, frequent, and drug-refractory PACs in the absence of AF (group A) and 35 patients with PACs-induced AF (group B) were enrolled. Coupling intervals (CoIs) of PACs were compared. Premature atrial contractions were mapped by the point-by-point and/or circular mapping technique. Focal ablation or pulmonary vein/superior vena cava isolation was applied as appropriate. A total of 35 ectopic foci were identified in group A. The majority of them were at pulmonary vein (PV) (n = 7), crista terminalis (n = 6), and para-Hisian area (n = 6). In group B, ectopic foci were in left-sided PVs in 21 patients, in right-sided PVs in 13 patients, and in SVC in 1 patient. There was significant difference in CoIs of PACs triggering AF and those from PVs and non-PV areas but without causing AF (362.8 +/- 23.0 ms vs. 470.6 +/- 60.1 ms vs. 515.6 +/- 77.2 ms, P< 0.001). Premature atrial contractions were abolished in 32 of 35 patients from group A and in all patients from group B. At the end of follow-up, 29 patients in group A and 28 patients in group B were free of recurrence (off antiarrhythmic drugs) after the initial ablation (P =0.97). Conclusions: Frequent PACs in the absence of AF were characterized as having their predilection sites and longer CoIs than those inducing AF. Catheter ablation was effective to eliminate symptomatic, frequent, and drug-refractory PACs. PMID- 27702871 TI - Impact of concomitant atrial fibrillation on the prognosis of Takotsubo cardiomyopathy. AB - Aims: Previous studies revealed that patients with Takotsubo cardiomyopathy (TTC) have a higher mortality rate than the general population. Supraventricular tachycardia is a well-known complication of TTC. This study was performed to determine the short- and long-term prognostic impact of atrial fibrillation associated with TTC patients. Methods and results: Our institutional database constituted a collective of 114 patients diagnosed with TTC from 2003 to 2015. The patients were divided into two groups according to the presence (n = 21, 18.4%) or absence (n = 93, 81.5%) of atrial fibrillation. The endpoint was a composite of in-hospital events (thromboembolic events and life-threatening arrhythmias), all-cause mortality, rehospitalization due to heart failure, stroke, and the recurrence of TTC. The in-hospital mortality, 30-day mortality, and long-term mortality were significantly higher in the atrial fibrillation group. Kaplan-Meier analysis indicated a significantly lower event-free survival rate over a mean follow-up of 3 years in the atrial fibrillation group than that in the non-atrial fibrillation group (log-rank, P < 0.01). In a multivariate cox regression analysis, atrial fibrillation (hazard ratio, HR 2.3, 95% confidence interval, CI: 1.1-4.9, P < 0.05) and EF <= 35% (HR 2.0, 95% CI: 1.1-3.8, P < 0.05) were the only independent predictors of a primary endpoint. Conclusion: Rates of in-hospital events and short- as well as long-term mortality were significantly higher in TTC patients suffering from atrial fibrillation compared with patients without atrial fibrillation. PMID- 27702872 TI - Study on the influence of oxidative stress on the fibrillization of fibrinogen. AB - Human fibrinogen is an important coagulation factor as well as an independent predictor of coronary heart disease and stroke. Analysis of dysfibrinogens may provide useful information and help us to understand the molecular defects in fibrin polymerization. In the present study, we investigated the influence of oxidative stress of fibrinogen induced by H2O2 on the polymerization state of fibrin. UV absorbance spectroscopy, circular dichroism, zeta-potential, dynamic light scattering and steady shear viscosity were all employed to study the influence of oxidative stress on the molecular structure, the surface charges, and the size and shape of fibrinogen molecules. The fibrin morphology obtained was imaged and investigated using atomic force microscopy. The results demonstrated that the cross-linking, branching and height distribution of formed fibrin will be influenced by the oxidative stress of fibrinogen. This study presents new insights into the aggregation behaviour of fibrinogen and will be helpful to understand the formation mechanism of thrombosis under oxidative stress.

PMID- 27702878 TI - Functional assessment of cerebral artery stenosis: A pilot study based on computational fluid dynamics. AB - The fractional pressure ratio is introduced to quantitatively assess the hemodynamic significance of severe intracranial stenosis. A computational fluid dynamics-based method is proposed to non-invasively compute the FPRCFD and compared against fractional pressure ratio measured by an invasive technique. Eleven patients with severe intracranial stenosis considered for endovascular intervention were recruited and an invasive procedure was performed to measure the distal and the aortic pressure ( Pd and Pa). The fractional pressure ratio was calculated as [Formula: see text]. The computed tomography angiography was used to reconstruct three-dimensional (3D) arteries for each patient. Cerebral hemodynamics was then computed for the arteries using a mathematical model governed by Navier-Stokes equations and with the outflow conditions imposed by a model of distal resistance and compliance. The non-invasive [Formula: see text], [Formula: see text], and FPRCFD were then obtained from the computational fluid dynamics calculation using a 16-core parallel computer. The invasive and non invasive parameters were tested by statistical analysis. For this group of patients, the computational fluid dynamics method achieved comparable results with the invasive measurements. The fractional pressure ratio and FPRCFD are very close and highly correlated, but not linearly proportional, with the percentage of stenosis. The proposed computational fluid dynamics method can potentially be useful in assessing the functional alteration of cerebral stenosis. PMID- 27702879 TI - Pulsatility and high shear stress deteriorate barrier phenotype in brain microvascular endothelium. AB - Microvascular endothelial cells at the blood-brain barrier exhibit a protective phenotype, which is highly induced by biochemical and biomechanical stimuli. Amongst them, shear stress enhances junctional tightness and limits transport at capillary-like levels. Abnormal flow patterns can reduce functional features of macrovascular endothelium. We now examine if this is true in brain microvascular endothelial cells. We suggest in this paper a complex response of endothelial cells to aberrant forces under different flow domains. Human brain microvascular endothelial cells were exposed to physiological or abnormal flow patterns. Physiologic shear (10-20 dyn/cm2) upregulates expression of tight junction markers Zona Occludens 1 (1.7-fold) and Claudin-5 (more than 2-fold). High shear stress (40 dyn/cm2) and/or pulsatility decreased their expression to basal levels and altered junctional morphology. We exposed cells to pathological shear stress patterns followed by capillary-like conditions. Results showed reversible recovery on the expression of tight junction markers. Flow protection of barrier phenotype commensurate with junctional signaling pathways decrease (Src, 0.25 fold, ERK, 0.77-fold) when compared to static conditions. This decrease was lost under high shear and pulsatile flow. In conclusion, abnormal shear stress inherent to systemic vascular disease leads to barrier impairment, which could be reverted by hemodynamic interventions. PMID- 27702880 TI - Imaging of brain oxygenation with magnetic resonance imaging: A validation with positron emission tomography in the healthy and tumoural brain. AB - The partial pressure in oxygen remains challenging to map in the brain. Two main strategies exist to obtain surrogate measures of tissue oxygenation: the tissue saturation studied by magnetic resonance imaging (StO2-MRI) and the identification of hypoxia by a positron emission tomography (PET) biomarker with 3-[18F]fluoro-1-(2-nitro-1-imidazolyl)-2-propanol ([18F]-FMISO) as the leading radiopharmaceutical. Nonetheless, a formal validation of StO2-MRI against FMISO PET has not been performed. The objective of our studies was to compare the two approaches in (a) the normal rat brain when the rats were submitted to hypoxemia; (b) animals implanted with four tumour types differentiated by their oxygenation. Rats were submitted to normoxic and hypoxemic conditions. For the brain tumour experiments, U87-MG, U251-MG, 9L and C6 glioma cells were orthotopically inoculated in rats. For both experiments, StO2-MRI and [18F]-FMISO PET were performed sequentially. Under hypoxemia conditions, StO2-MRI revealed a decrease in oxygen saturation in the brain. Nonetheless, [18F]-FMISO PET, pimonidazole immunohistochemistry and molecular biology were insensitive to hypoxia. Within the context of tumours, StO2-MRI was able to detect hypoxia in the hypoxic models, mimicking [18F]-FMISO PET with high sensitivity/specificity. Altogether, our data clearly support that, in brain pathologies, StO2-MRI could be a robust and specific imaging biomarker to assess hypoxia. PMID- 27702881 TI - Minimally invasive beat-by-beat monitoring of cardiac power in normal hearts and during acute ventricular dysfunction. AB - Cardiac power, the product of aortic flow and blood pressure, appears to be a fundamental cardiovascular parameter. The simplified version named cardiac power output (CPO), calculated as the product of cardiac output (CO) in L/min and mean arterial pressure (MAP) in mmHg divided by 451, has shown great ability to predict outcome in a broad spectrum of cardiac disease. Beat-by-beat evaluation of cardiac power (PWR) therefore appears to be a possibly valuable addition when monitoring circulatory unstable patients, providing parameters of overall cardiovascular function. We have developed a minimally invasive system for cardiac power measurement, and aimed in this study to compare this system to an invasive method (ttPWR). Seven male anesthetized farm pigs were included. A laptop with in-house software gathered audio from Doppler signals of aortic flow and blood pressure from the patient monitor to continuously calculate and display a minimally invasive cardiac power trace (uPWR). The time integral per cardiac cycle (uPWR-integral) represents cardiac work, and was compared to the invasive counterpart (ttPWR-integral). Signals were obtained at baseline, during mechanically manipulated preload and afterload, before and after induced global ischemic left ventricular dysfunction. We found that the uPWR-integral overestimated compared to the ttPWR-integral by about 10% (P < 0.001) in both normal hearts and during ventricular dysfunction. Bland-Altman limits of agreement were at +0.060 and -0.054 J, without increasing spread over the range. In conclusion we find that the minimally invasive system follows its invasive counterpart, and is ready for clinical research of cardiac power parameters. PMID- 27702882 TI - Ischemia/reperfusion-induced alterations of enzymatic and signaling functions of the rat cardiac Na+/K+-ATPase: protection by ouabain preconditioning. AB - Cardiac glycosides (CG) are traditionally known as positive cardiac inotropes that inhibit Na+/K+-ATPase-dependent ion transport. CG also trigger-specific signaling pathways through the cardiac Na+/K+-ATPase, with beneficial effects in ischemia/reperfusion (I/R) injury (e.g., ouabain preconditioning, known as OPC) and hypertrophy. Our current understanding of hypersensitivity to CG and subsequent toxicity in the ischemic heart is mostly based on specific I/R-induced alterations of the Na+/K+-ATPase enzymatic function and has remained incomplete. The primary goal of this study was to investigate and compare the impact of I/R on Na+/K+-ATPase enzymatic and signaling functions. Second, we assessed the impact of OPC on both functions. Langendorff-perfused rat hearts were exposed to 30 min of ischemia and 30 min of reperfusion. At the inotropic concentration of 50 MUmol/L, ouabain increased ERK and Akt phosphorylation in control hearts. In I/R hearts, this concentration did not induced positive inotropy and failed to induce Akt or ERK phosphorylation. The inotropic response to dobutamine as well as insulin signaling persisted, suggesting specific alterations of Na+/K+-ATPase. Indeed, Na+/K+-ATPase protein expression was intact, but the enzyme activity was decreased by 60% and the enzymatic function of the isoform with high affinity for ouabain was abolished following I/R. Strikingly, OPC prevented all I/R-induced alterations of the receptor. Further studies are needed to reveal the respective roles of I/R-induced modulations of Na+/K+-ATPase enzymatic and signaling functions in cardiomyocyte death. PMID- 27702883 TI - Internal carotid artery blood flow in healthy awake subjects is reduced by simulated hypovolemia and noninvasive mechanical ventilation. AB - Intact cerebral blood flow (CBF) is essential for cerebral metabolism and function, whereas hypoperfusion in relation to hypovolemia and hypocapnia can lead to severe cerebral damage. This study was designed to assess internal carotid artery blood flow (ICA-BF) during simulated hypovolemia and noninvasive positive pressure ventilation (PPV) in young healthy humans. Beat-by-beat blood velocity (ICA and aorta) were measured by Doppler ultrasound during normovolemia and simulated hypovolemia (lower body negative pressure), with or without PPV in 15 awake subjects. Heart rate, plethysmographic finger arterial pressure, respiratory frequency, and end-tidal CO2 (ETCO2) were also recorded. Cardiac index (CI) and ICA-BF were calculated beat-by-beat. Medians and 95% confidence intervals and Wilcoxon signed rank test for paired samples were used to test the difference between conditions. Effects on ICA-BF were modeled by linear mixed effects regression analysis. During spontaneous breathing, ICA-BF was reduced from normovolemia (247, 202-284 mL/min) to hypovolemia (218, 194-271 mL/min). During combined PPV and hypovolemia, ICA-BF decreased by 15% (200, 152-231 mL/min, P = 0.001). Regression analysis attributed this fall to concurrent reductions in CI (beta: 43.2, SE: 17.1, P = 0.013) and ETCO2 (beta: 32.8, SE: 9.3, P = 0.001). Mean arterial pressure was maintained and did not contribute to ICA-BF variance. In healthy awake subjects, ICA-BF was significantly reduced during simulated hypovolemia combined with noninvasive PPV Reductions in CI and ETCO2 had additive effects on ICA-BF reduction. In hypovolemic patients, even low pressure noninvasive ventilation may cause clinically relevant reductions in CBF, despite maintained arterial blood pressure.

AB - Pathological cardiac hypertrophy is an independent risk factor of heart failure. However, we still lack effective methods to reverse cardiac hypertrophy. DUSP12 is a member of the dual specific phosphatase (DUSP) family, which is characterized by its DUSP activity to dephosphorylate both tyrosine and serine/threonine residues on one substrate. Some DUSPs have been identified as being involved in the regulation of cardiac hypertrophy. However, the role of DUSP12 during pathological cardiac hypertrophy is still unclear. In the present study, we observed a significant decrease in DUSP12 expression in hypertrophic hearts and cardiomyocytes. Using a genetic loss-of-function murine model, we demonstrated that DUSP12 deficiency apparently aggravated pressure overload induced cardiac hypertrophy and fibrosis as well as impaired cardiac function, whereas cardiac-specific overexpression of DUPS12 was capable of reversing this hypertrophic and fibrotic phenotype and improving contractile function. Furthermore, we demonstrated that JNK1/2 activity but neither ERK1/2 nor p38 activity was increased in the DUSP12 deficient group and decreased in the DUSP12 overexpression group both in vitro and in vivo under hypertrophic stress conditions. Pharmacological inhibition of JNK1/2 activity (SP600125) is capable of reversing the hypertrophic phenotype in DUSP12 knockout (KO) mice. DUSP12 protects against pathological cardiac hypertrophy and related pathologies. This regulatory role of DUSP12 is primarily through c-Jun N-terminal kinase (JNK) inhibition. DUSP12 could be a promising therapeutic target of pathological cardiac hypertrophy. DUSP12 is down-regulated in hypertrophic hearts. An absence of DUSP12 aggravated cardiac hypertrophy, whereas cardiomyocyte-specific DUSP12 overexpression can alleviate this hypertrophic phenotype with improved cardiac function. Further study demonstrated that DUSP12 inhibited JNK activity to attenuate pathological cardiac hypertrophy. PMID- 27702884 TI - Retino-cortical stimulus frequency-dependent gamma coupling: evidence and functional implications of oscillatory potentials. AB - Long-range gamma band EEG oscillations mediate information transmission between distant brain regions. Gamma band-based coupling may not be restricted to cortex to-cortex communication but may include extracortical parts of the visual system. The retinogram and visual event-related evoked potentials exhibit time-locked, forward propagating oscillations that are candidates of gamma oscillatory coupling between the retina and the visual cortex. In this study, we tested if this gamma coupling is present as indicated by the coherence of gamma-range (70 200 Hz) oscillatory potentials (OPs) recorded simultaneously from the retina and the primary visual cortex in freely moving, adult rats. We found significant retino-cortical OP coherence in a wide range of stimulus duration (0.01-1000 msec), stimulus intensity (800-5000 mcd/mm2), interstimulus interval (10-400 msec), and stimulus frequency (0.25-25 Hz). However, at low stimulus frequencies, the OPs were time-locked, flickering light at 25 Hz entrained continuous OP coherence (steady-state response, SSR). Our results suggest that the retina and the visual cortex exhibit oscillatory coupling at high-gamma frequency with precise time locking and synchronization of information transfer from the retina to the visual cortex, similar to cortico-cortical gamma coupling. The temporal fusion of retino-cortical gamma coherence at stimulus rates of theater movies may explain the mechanism of the visual illusion of continuity. How visual perception depends on early transformations of ascending sensory information is incompletely understood. By simultaneous measurement of flash-evoked potentials in the retina and the visual cortex in awake, freely moving rats, we demonstrate for the first time that time-locked gamma oscillatory potentials exhibit stable retino-cortical synchrony across a wide range of stimulus parameters and that the temporal continuity of coherence changes with stimulus frequency according to the expected change in the visual illusion of continuity. PMID- 27702886 TI - "So Much of This Story Could Be Me": Men's Use of Support in Online Infertility Discussion Boards. AB - Past research has suggested that social support can reduce the negative psychological consequences associated with infertility. Online discussion boards (ODBs) appear to be a novel and valuable venue for men with fertility problems to acquire support from similar others. Research has not employed a social support framework to classify the types of support men are offered and receive. Using template, content, and thematic analysis, this study sought to identify what types of social support men seek and receive on online infertility discussion boards while exploring how men having fertility problems use appraisal support to assist other men. One hundred and ninety-nine unique users were identified on two online infertility discussion boards. Four types of social support (appraisal, emotional, informational, and instrumental) were evident on ODBs, with appraisal support (36%) being used most often to support other men. Within appraisal support, five themes were identified that showed how men communicate this type of support to assist other men: "At the end of the day, we're all emotionally exhausted"; "So much of this could be me, infertility happens more than you think"; "I've also felt like the worst husband in the world"; "It's just something that nobody ever talks about so it's really shocking to hear"; "I say this as a man, you're typing my thoughts exactly." These findings confirm how ODBs can be used as a potential medium to expand one's social network and acquire support from people who have had a similar experience. PMID- 27702887 TI - Don't Change Much. AB - Few studies have assessed differences in the prevalence of and economic burden attributable to tobacco smoking, excess weight, physical inactivity, and alcohol use by gender. This article examines these gender differences in Canadians between the ages of 30 and 64 years. It also estimates the potential cost avoidance if the prevalence of the four risk factors (RFs) were reduced modestly in males. Data on the prevalence of the RFs and the relative risk of disease associated with each of the RFs were combined to calculate population attributable fractions. A prevalence-based cost-of-illness approach was used to estimate the economic burden associated with the four RFs. Middle-aged Canadian males are more likely to smoke tobacco (26.4% vs. 20.2%), consume hazardous or harmful levels of alcohol (14.6% vs. 8.2%), and have excess weight (65.6% vs. 47.1%) than middle-aged Canadian females, resulting in an annual economic burden that is 27% higher in males than females. No significant differences were observed in the proportion of males who are physically inactive (48.4% vs. 49.4%). Modelling only a 1% annual relative reduction each year through to 2036 would result in a cumulative cost avoidance between 2013 and 2036 of $50.7 billion. The differences in RF prevalence between middle-aged males and females have an important effect on the population's economic burden. A modest annual reduction in the four RFs in males can significantly affect population health and the economy over time. PMID- 27702888 TI - Deep sequencing of 10,000 human genomes. AB - We report on the sequencing of 10,545 human genomes at 30*-40* coverage with an emphasis on quality metrics and novel variant and sequence discovery. We find that 84% of an individual human genome can be sequenced confidently. This high confidence region includes 91.5% of exon sequence and 95.2% of known pathogenic variant positions. We present the distribution of over 150 million single nucleotide variants in the coding and noncoding genome. Each newly sequenced genome contributes an average of 8,579 novel variants. In addition, each genome carries on average 0.7 Mb of sequence that is not found in the main build of the hg38 reference genome. The density of this catalog of variation allowed us to construct high-resolution profiles that define genomic sites that are highly intolerant of genetic variation. These results indicate that the data generated by deep genome sequencing is of the quality necessary for clinical use. PMID- 27702889 TI - Black carbon solar absorption suppresses turbulence in the atmospheric boundary layer. AB - The introduction of cloud condensation nuclei and radiative heating by sunlight absorbing aerosols can modify the thickness and coverage of low clouds, yielding significant radiative forcing of climate. The magnitude and sign of changes in cloud coverage and depth in response to changing aerosols are impacted by turbulent dynamics of the cloudy atmosphere, but integrated measurements of aerosol solar absorption and turbulent fluxes have not been reported thus far. Here we report such integrated measurements made from unmanned aerial vehicles (UAVs) during the CARDEX (Cloud Aerosol Radiative Forcing and Dynamics Experiment) investigation conducted over the northern Indian Ocean. The UAV and surface data reveal a reduction in turbulent kinetic energy in the surface mixed layer at the base of the atmosphere concurrent with an increase in absorbing black carbon aerosols. Polluted conditions coincide with a warmer and shallower surface mixed layer because of aerosol radiative heating and reduced turbulence. The polluted surface mixed layer was also observed to be more humid with higher relative humidity. Greater humidity enhances cloud development, as evidenced by polluted clouds that penetrate higher above the top of the surface mixed layer. Reduced entrainment of dry air into the surface layer from above the inversion capping the surface mixed layer, due to weaker turbulence, may contribute to higher relative humidity in the surface layer during polluted conditions. Measurements of turbulence are important for studies of aerosol effects on clouds. Moreover, reduced turbulence can exacerbate both the human health impacts of high concentrations of fine particles and conditions favorable for low visibility fog events. PMID- 27702892 TI - Predictability and hierarchy in Drosophila behavior. AB - Even the simplest of animals exhibit behavioral sequences with complex temporal dynamics. Prominent among the proposed organizing principles for these dynamics has been the idea of a hierarchy, wherein the movements an animal makes can be understood as a set of nested subclusters. Although this type of organization holds potential advantages in terms of motion control and neural circuitry, measurements demonstrating this for an animal's entire behavioral repertoire have been limited in scope and temporal complexity. Here, we use a recently developed unsupervised technique to discover and track the occurrence of all stereotyped behaviors performed by fruit flies moving in a shallow arena. Calculating the optimally predictive representation of the fly's future behaviors, we show that fly behavior exhibits multiple time scales and is organized into a hierarchical structure that is indicative of its underlying behavioral programs and its changing internal states.

PMID- 27702890 TI - Hypoxia-activated cytotoxic agent tirapazamine enhances hepatic artery ligation induced killing of liver tumor in HBx transgenic mice. AB - Transarterial chemoembolization (TACE) is the main treatment for intermediate stage hepatocellular carcinoma (HCC) with Barcelona Clinic Liver Cancer classification because of its exclusive arterial blood supply. Although TACE achieves substantial necrosis of the tumor, complete tumor necrosis is uncommon, and the residual tumor generally rapidly recurs. We combined tirapazamine (TPZ), a hypoxia-activated cytotoxic agent, with hepatic artery ligation (HAL), which recapitulates transarterial embolization in mouse models, to enhance the efficacy of TACE. The effectiveness of this combination treatment was examined in HCC that spontaneously developed in hepatitis B virus X protein (HBx) transgenic mice. We proved that the tumor blood flow in this model was exclusively supplied by the hepatic artery, in contrast to conventional orthotopic HCC xenografts that receive both arterial and venous blood supplies. At levels below the threshold oxygen levels created by HAL, TPZ was activated and killed the hypoxic cells, but spared the normoxic cells. This combination treatment clearly limited the toxicity of TPZ to HCC, which caused the rapid and near-complete necrosis of HCC. In conclusion, the combination of TPZ and HAL showed a synergistic tumor killing activity that was specific for HCC in HBx transgenic mice. This preclinical study forms the basis for the ongoing clinical program for the TPZ-TACE regimen in HCC treatment. PMID- 27702891 TI - Label-free imaging of the native, living cellular nanoarchitecture using partial wave spectroscopic microscopy. AB - The organization of chromatin is a regulator of molecular processes including transcription, replication, and DNA repair. The structures within chromatin that regulate these processes span from the nucleosomal (10-nm) to the chromosomal (>200-nm) levels, with little known about the dynamics of chromatin structure between these scales due to a lack of quantitative imaging technique in live cells. Previous work using partial-wave spectroscopic (PWS) microscopy, a quantitative imaging technique with sensitivity to macromolecular organization between 20 and 200 nm, has shown that transformation of chromatin at these length scales is a fundamental event during carcinogenesis. As the dynamics of chromatin likely play a critical regulatory role in cellular function, it is critical to develop live-cell imaging techniques that can probe the real-time temporal behavior of the chromatin nanoarchitecture. Therefore, we developed a live-cell PWS technique that allows high-throughput, label-free study of the causal relationship between nanoscale organization and molecular function in real time. In this work, we use live-cell PWS to study the change in chromatin structure due to DNA damage and expand on the link between metabolic function and the structure of higher-order chromatin. In particular, we studied the temporal changes to chromatin during UV light exposure, show that live-cell DNA-binding dyes induce damage to chromatin within seconds, and demonstrate a direct link between higher order chromatin structure and mitochondrial membrane potential. Because biological function is tightly paired with structure, live-cell PWS is a powerful tool to study the nanoscale structure-function relationship in live cells.

PMID- 27702895 TI - Sustained antigen availability during germinal center initiation enhances antibody responses to vaccination. AB - Natural infections expose the immune system to escalating antigen and inflammation over days to weeks, whereas nonlive vaccines are single bolus events. We explored whether the immune system responds optimally to antigen kinetics most similar to replicating infections, rather than a bolus dose. Using HIV antigens, we found that administering a given total dose of antigen and adjuvant over 1-2 wk through repeated injections or osmotic pumps enhanced humoral responses, with exponentially increasing (exp-inc) dosing profiles eliciting >10-fold increases in antibody production relative to bolus vaccination post prime. Computational modeling of the germinal center response suggested that antigen availability as higher-affinity antibodies evolve enhances antigen capture in lymph nodes. Consistent with these predictions, we found that exp-inc dosing led to prolonged antigen retention in lymph nodes and increased Tfh cell and germinal center B-cell numbers. Thus, regulating the antigen and adjuvant kinetics may enable increased vaccine potency. PMID- 27702896 TI - Mutational landscape of EGFR-, MYC-, and Kras-driven genetically engineered mouse models of lung adenocarcinoma. AB - Genetically engineered mouse models (GEMMs) of cancer are increasingly being used to assess putative driver mutations identified by large-scale sequencing of human cancer genomes. To accurately interpret experiments that introduce additional mutations, an understanding of the somatic genetic profile and evolution of GEMM tumors is necessary. Here, we performed whole-exome sequencing of tumors from three GEMMs of lung adenocarcinoma driven by mutant epidermal growth factor receptor (EGFR), mutant Kirsten rat sarcoma viral oncogene homolog (Kras), or overexpression of MYC proto-oncogene. Tumors from EGFR- and Kras-driven models exhibited, respectively, 0.02 and 0.07 nonsynonymous mutations per megabase, a dramatically lower average mutational frequency than observed in human lung adenocarcinomas. Tumors from models driven by strong cancer drivers (mutant EGFR and Kras) harbored few mutations in known cancer genes, whereas tumors driven by MYC, a weaker initiating oncogene in the murine lung, acquired recurrent clonal oncogenic Kras mutations. In addition, although EGFR- and Kras-driven models both exhibited recurrent whole-chromosome DNA copy number alterations, the specific chromosomes altered by gain or loss were different in each model. These data demonstrate that GEMM tumors exhibit relatively simple somatic genotypes compared with human cancers of a similar type, making these autochthonous model systems useful for additive engineering approaches to assess the potential of novel mutations on tumorigenesis, cancer progression, and drug sensitivity. PMID- 27702897 TI - Real-time analysis of RAG complex activity in V(D)J recombination. AB - Single-molecule FRET (smFRET) and single-molecule colocalization (smCL) assays have allowed us to observe the recombination-activating gene (RAG) complex reaction mechanism in real time. Our smFRET data have revealed distinct bending modes at recombination signal sequence (RSS)-conserved regions before nicking and synapsis. We show that high mobility group box 1 (HMGB1) acts as a cofactor in stabilizing conformational changes at the 12RSS heptamer and increasing RAG1/2 binding affinity for 23RSS. Using smCL analysis, we have quantitatively measured RAG1/2 dwell time on 12RSS, 23RSS, and non-RSS DNA, confirming a strict RSS molecular specificity that was enhanced in the presence of a partner RSS in solution. Our studies also provide single-molecule determination of rate constants that were previously only possible by indirect methods, allowing us to conclude that RAG binding, bending, and synapsis precede catalysis. Our real-time analysis offers insight into the requirements for RSS-RSS pairing, architecture of the synaptic complex, and dynamics of the paired RSS substrates. We show that the synaptic complex is extremely stable and that heptamer regions of the 12RSS and 23RSS substrates in the synaptic complex are closely associated in a stable conformational state, whereas nonamer regions are perpendicular. Our data provide an enhanced and comprehensive mechanistic description of the structural dynamics and associated enzyme kinetics of variable, diversity, and joining [V(D)J] recombination. PMID- 27702898 TI - Decay of an active GPCR: Conformational dynamics govern agonist rebinding and persistence of an active, yet empty, receptor state. AB - Here, we describe two insights into the role of receptor conformational dynamics during agonist release (all-trans retinal, ATR) from the visual G protein-coupled receptor (GPCR) rhodopsin. First, we show that, after light activation, ATR can continually release and rebind to any receptor remaining in an active-like conformation. As with other GPCRs, we observe that this equilibrium can be shifted by either promoting the active-like population or increasing the agonist concentration. Second, we find that during decay of the signaling state an active like, yet empty, receptor conformation can transiently persist after retinal release, before the receptor ultimately collapses into an inactive conformation. The latter conclusion is based on time-resolved, site-directed fluorescence labeling experiments that show a small, but reproducible, lag between the retinal leaving the protein and return of transmembrane helix 6 (TM6) to the inactive conformation, as determined from tryptophan-induced quenching studies. Accelerating Schiff base hydrolysis and subsequent ATR dissociation, either by addition of hydroxylamine or introduction of mutations, further increased the time lag between ATR release and TM6 movement. These observations show that rhodopsin can bind its agonist in equilibrium like a traditional GPCR, provide evidence that an active GPCR conformation can persist even after agonist release, and raise the possibility of targeting this key photoreceptor protein by traditional pharmaceutical-based treatments. PMID- 27702900 TI - Architecture of a minimal signaling pathway explains the T-cell response to a 1 million-fold variation in antigen affinity and dose. AB - T cells must respond differently to antigens of varying affinity presented at different doses. Previous attempts to map peptide MHC (pMHC) affinity onto T-cell responses have produced inconsistent patterns of responses, preventing formulations of canonical models of T-cell signaling. Here, a systematic analysis of T-cell responses to 1 million-fold variations in both pMHC affinity and dose produced bell-shaped dose-response curves and different optimal pMHC affinities at different pMHC doses. Using sequential model rejection/identification algorithms, we identified a unique, minimal model of cellular signaling incorporating kinetic proofreading with limited signaling coupled to an incoherent feed-forward loop (KPL-IFF) that reproduces these observations. We show that the KPL-IFF model correctly predicts the T-cell response to antigen copresentation. Our work offers a general approach for studying cellular signaling that does not require full details of biochemical pathways. PMID- 27702902 TI - Isotopic overprinting of nitrification on denitrification as a ubiquitous and unifying feature of environmental nitrogen cycling. AB - Natural abundance nitrogen and oxygen isotopes of nitrate (delta15NNO3 and delta18ONO3) provide an important tool for evaluating sources and transformations of natural and contaminant nitrate (NO3-) in the environment. Nevertheless, conventional interpretations of NO3- isotope distributions appear at odds with patterns emerging from studies of nitrifying and denitrifying bacterial cultures. To resolve this conundrum, we present results from a numerical model of NO3- isotope dynamics, demonstrating that deviations in delta18ONO3 vs. delta15NNO3 from a trajectory of 1 expected for denitrification are explained by isotopic over-printing from coincident NO3- production by nitrification and/or anammox. The analysis highlights two driving parameters: (i) the delta18O of ambient water and (ii) the relative flux of NO3- production under net denitrifying conditions, whether catalyzed aerobically or anaerobically. In agreement with existing analyses, dual isotopic trajectories >1, characteristic of marine denitrifying systems, arise predominantly under elevated rates of NO2- reoxidation relative to NO3- reduction (>50%) and in association with the elevated delta18O of seawater. This result specifically implicates aerobic nitrification as the dominant NO3- producing term in marine denitrifying systems, as stoichiometric constraints indicate anammox-based NO3- production cannot account for trajectories >1. In contrast, trajectories <1 comprise the majority of model solutions, with those representative of aquifer conditions requiring lower NO2- reoxidation fluxes (<15%) and the influence of the lower delta18O of freshwater. Accordingly, we suggest that widely observed delta18ONO3 vs. delta15NNO3 trends in freshwater systems (<1) must result from concurrent NO3- production by anammox in anoxic aquifers, a process that has been largely overlooked. PMID- 27702901 TI - Allelic barley MLA immune receptors recognize sequence-unrelated avirulence effectors of the powdery mildew pathogen. AB - Disease-resistance genes encoding intracellular nucleotide-binding domain and leucine-rich repeat proteins (NLRs) are key components of the plant innate immune system and typically detect the presence of isolate-specific avirulence (AVR) effectors from pathogens. NLR genes define the fastest-evolving gene family of flowering plants and are often arranged in gene clusters containing multiple paralogs, contributing to copy number and allele-specific NLR variation within a host species. Barley mildew resistance locus a (Mla) has been subject to extensive functional diversification, resulting in allelic resistance specificities each recognizing a cognate, but largely unidentified, AVRa gene of the powdery mildew fungus, Blumeria graminis f. sp. hordei (Bgh). We applied a transcriptome-wide association study among 17 Bgh isolates containing different AVRa genes and identified AVRa1 and AVRa13, encoding candidate-secreted effectors recognized by Mla1 and Mla13 alleles, respectively. Transient expression of the effector genes in barley leaves or protoplasts was sufficient to trigger Mla1 or Mla13 allele-specific cell death, a hallmark of NLR receptor-mediated immunity. AVRa1 and AVRa13 are phylogenetically unrelated, demonstrating that certain allelic MLA receptors evolved to recognize sequence-unrelated effectors. They are ancient effectors because corresponding loci are present in wheat powdery mildew. AVRA1 recognition by barley MLA1 is retained in transgenic Arabidopsis, indicating that AVRA1 directly binds MLA1 or that its recognition involves an evolutionarily conserved host target of AVRA1 Furthermore, analysis of transcriptome-wide sequence variation among the Bgh isolates provides evidence for Bgh population structure that is partially linked to geographic isolation. PMID- 27702903 TI - Nonlinear two-dimensional terahertz photon echo and rotational spectroscopy in the gas phase. AB - Ultrafast 2D spectroscopy uses correlated multiple light-matter interactions for retrieving dynamic features that may otherwise be hidden under the linear spectrum; its extension to the terahertz regime of the electromagnetic spectrum, where a rich variety of material degrees of freedom reside, remains an experimental challenge. We report a demonstration of ultrafast 2D terahertz spectroscopy of gas-phase molecular rotors at room temperature. Using time delayed terahertz pulse pairs, we observe photon echoes and other nonlinear signals resulting from molecular dipole orientation induced by multiple terahertz field-dipole interactions. The nonlinear time domain orientation signals are mapped into the frequency domain in 2D rotational spectra that reveal J-state resolved nonlinear rotational dynamics. The approach enables direct observation of correlated rotational transitions and may reveal rotational coupling and relaxation pathways in the ground electronic and vibrational state. PMID- 27702904 TI - Theory of prokaryotic genome evolution. AB - Bacteria and archaea typically possess small genomes that are tightly packed with protein-coding genes. The compactness of prokaryotic genomes is commonly perceived as evidence of adaptive genome streamlining caused by strong purifying selection in large microbial populations. In such populations, even the small cost incurred by nonfunctional DNA because of extra energy and time expenditure is thought to be sufficient for this extra genetic material to be eliminated by selection. However, contrary to the predictions of this model, there exists a consistent, positive correlation between the strength of selection at the protein sequence level, measured as the ratio of nonsynonymous to synonymous substitution rates, and microbial genome size. Here, by fitting the genome size distributions in multiple groups of prokaryotes to predictions of mathematical models of population evolution, we show that only models in which acquisition of additional genes is, on average, slightly beneficial yield a good fit to genomic data. These results suggest that the number of genes in prokaryotic genomes reflects the equilibrium between the benefit of additional genes that diminishes as the genome grows and deletion bias (i.e., the rate of deletion of genetic material being slightly greater than the rate of acquisition). Thus, new genes acquired by microbial genomes, on average, appear to be adaptive. The tight spacing of protein-coding genes likely results from a combination of the deletion bias and purifying selection that efficiently eliminates nonfunctional, noncoding sequences. PMID- 27702905 TI - How seabirds plunge-dive without injuries. AB - In nature, several seabirds (e.g., gannets and boobies) dive into water at up to 24 m/s as a hunting mechanism; furthermore, gannets and boobies have a slender neck, which is potentially the weakest part of the body under compression during high-speed impact. In this work, we investigate the stability of the bird's neck during plunge-diving by understanding the interaction between the fluid forces acting on the head and the flexibility of the neck. First, we use a salvaged bird to identify plunge-diving phases. Anatomical features of the skull and neck were acquired to quantify the effect of beak geometry and neck musculature on the stability during a plunge-dive. Second, physical experiments using an elastic beam as a model for the neck attached to a skull-like cone revealed the limits for the stability of the neck during the bird's dive as a function of impact velocity and geometric factors. We find that the neck length, neck muscles, and diving speed of the bird predominantly reduce the likelihood of injury during the plunge-dive. Finally, we use our results to discuss maximum diving speeds for humans to avoid injury.

PMID- 27702906 TI - Ataluren stimulates ribosomal selection of near-cognate tRNAs to promote nonsense suppression. AB - A premature termination codon (PTC) in the ORF of an mRNA generally leads to production of a truncated polypeptide, accelerated degradation of the mRNA, and depression of overall mRNA expression. Accordingly, nonsense mutations cause some of the most severe forms of inherited disorders. The small-molecule drug ataluren promotes therapeutic nonsense suppression and has been thought to mediate the insertion of near-cognate tRNAs at PTCs. However, direct evidence for this activity has been lacking. Here, we expressed multiple nonsense mutation reporters in human cells and yeast and identified the amino acids inserted when a PTC occupies the ribosomal A site in control, ataluren-treated, and aminoglycoside-treated cells. We find that ataluren's likely target is the ribosome and that it produces full-length protein by promoting insertion of near cognate tRNAs at the site of the nonsense codon without apparent effects on transcription, mRNA processing, mRNA stability, or protein stability. The resulting readthrough proteins retain function and contain amino acid replacements similar to those derived from endogenous readthrough, namely Gln, Lys, or Tyr at UAA or UAG PTCs and Trp, Arg, or Cys at UGA PTCs. These insertion biases arise primarily from mRNA:tRNA mispairing at codon positions 1 and 3 and reflect, in part, the preferred use of certain nonstandard base pairs, e.g., U-G. Ataluren's retention of similar specificity of near-cognate tRNA insertion as occurs endogenously has important implications for its general use in therapeutic nonsense suppression. PMID- 27702899 TI - Bayesian model reveals latent atrophy factors with dissociable cognitive trajectories in Alzheimer's disease. AB - We used a data-driven Bayesian model to automatically identify distinct latent factors of overlapping atrophy patterns from voxelwise structural MRIs of late onset Alzheimer's disease (AD) dementia patients. Our approach estimated the extent to which multiple distinct atrophy patterns were expressed within each participant rather than assuming that each participant expressed a single atrophy factor. The model revealed a temporal atrophy factor (medial temporal cortex, hippocampus, and amygdala), a subcortical atrophy factor (striatum, thalamus, and cerebellum), and a cortical atrophy factor (frontal, parietal, lateral temporal, and lateral occipital cortices). To explore the influence of each factor in early AD, atrophy factor compositions were inferred in beta-amyloid-positive (Abeta+) mild cognitively impaired (MCI) and cognitively normal (CN) participants. All three factors were associated with memory decline across the entire clinical spectrum, whereas the cortical factor was associated with executive function decline in Abeta+ MCI participants and AD dementia patients. Direct comparison between factors revealed that the temporal factor showed the strongest association with memory, whereas the cortical factor showed the strongest association with executive function. The subcortical factor was associated with the slowest decline for both memory and executive function compared with temporal and cortical factors. These results suggest that distinct patterns of atrophy influence decline across different cognitive domains. Quantification of this heterogeneity may enable the computation of individual-level predictions relevant for disease monitoring and customized therapies. Factor compositions of participants and code used in this article are publicly available for future research.

Its dermatologic manifestations include hair and nail changes and glossitis. Cases of generalized hyperpigmentation associated with vitamin B12 deficiency have rarely been reported. Localized hyperpigmentation is less frequently described, affecting palms, soles, and flexural areas. We report a rare case of reversible melasma-like cutaneous hyperpigmentation associated with pernicious anemia and discuss the possible mechanisms of this association. PMID- 27702909 TI - Transcriptome analysis of trigeminal ganglia following masseter muscle inflammation in rats. AB - BACKGROUND: Chronic pain in masticatory muscles is a major medical problem. Although mechanisms underlying persistent pain in masticatory muscles are not fully understood, sensitization of nociceptive primary afferents following muscle inflammation or injury contributes to muscle hyperalgesia. It is well known that craniofacial muscle injury or inflammation induces regulation of multiple genes in trigeminal ganglia, which is associated with muscle hyperalgesia. However, overall transcriptional profiles within trigeminal ganglia following masseter inflammation have not yet been determined. In the present study, we performed RNA sequencing assay in rat trigeminal ganglia to identify transcriptome profiles of genes relevant to hyperalgesia following inflammation of the rat masseter muscle. RESULTS: Masseter inflammation differentially regulated >3500 genes in trigeminal ganglia. Predominant biological pathways were predicted to be related with activation of resident non-neuronal cells within trigeminal ganglia or recruitment of immune cells. To focus our analysis on the genes more relevant to nociceptors, we selected genes implicated in pain mechanisms, genes enriched in small- to medium-sized sensory neurons, and genes enriched in TRPV1-lineage nociceptors. Among the 2320 candidate genes, 622 genes showed differential expression following masseter inflammation. When the analysis was limited to these candidate genes, pathways related with G protein-coupled signaling and synaptic plasticity were predicted to be enriched. Inspection of individual gene expression changes confirmed the transcriptional changes of multiple nociceptor genes associated with masseter hyperalgesia (e.g., Trpv1, Trpa1, P2rx3, Tac1, and Bdnf) and also suggested a number of novel probable contributors (e.g., Piezo2, Tmem100, and Hdac9). CONCLUSION: These findings should further advance our understanding of peripheral mechanisms involved in persistent craniofacial muscle pain conditions and provide a rational basis for identifying novel genes or sets of genes that can be potentially targeted for treating such conditions.

AB - This study examined psychosocial factors influencing smoking intention in Korean male middle school students. We used a descriptive cross-sectional design, based on the biopsychosocial model, to analyze data from 309 male adolescents aged 14 16 years in middle school. Of the psychological factors examined, stress and risk taking tendency were significantly associated with smoking intention. Of the social factors examined, social normative beliefs, close friends' and siblings' smoking, and low socioeconomic status were significant factors in smoking intention. The explanatory power of these variables in the predictive model was 23.1%. In conclusion, the unique psychological and social characteristics of adolescents should be reflected in interventions for smoking prevention. PMID- 27702912 TI - Frontal Hypoactivation During a Working Memory Task in Children With 22q11 Deletion Syndrome. AB - Impairments in executive function, such as working memory, are almost universal in children with chromosome 22q11.2 deletion syndrome. Delineating the neural underpinnings of these functions would enhance understanding of these impairments. In this study, children and adolescents with 22q11 deletion syndrome were compared with healthy control participants in a functional magnetic resonance imaging (MRI) study of working memory. When the 2-back condition was contrasted with the 1-back and 0-back conditions, the participants with 22q11 deletion syndrome showed lower activation in several brain areas involved in working memory-notably dorsolateral prefrontal cortex, anterior cingulate, and precuneus. This hypoactivation may be due to reduced gray matter volumes or white matter connectivity in the frontal and parietal regions, differences that have previously been documented in children with 22q11 deletion syndrome. Understanding differences in brain function will provide a foundation for future interventions to address the wide range of neurodevelopmental deficits observed in 22q11 deletion syndrome.

AB - This investigation was conducted to study the effects of tanshinone IIA (TIIA) on pulmonary arterial hypertension (PAH) in broilers. Two-hundred newly hatched Arbor Acre commercial broilers were randomly divided into 3 groups. All groups, with the exception of the control group (tap water), were given NaCl water (0.3%) starting on the d 15, and broilers in the protected group were fed a diet supplemented with TIIA (2.5 g/kg) starting on the d 15. On d 28, 35, 42, and 49, the ratio of the right ventricular weight to the total ventricular weight (RV: TV) and the values of other biochemical indicators for each group chickens were determined. The concentrations of interleukin-6 (IL-6), interleukin-1beta (IL 1beta), nuclear factor kappa (NF-kappaB), and P38 (a mitogen-activated protein kinase) were measured using enzyme-linked immune sorbent assays (ELISA). The results showed that the proportion of chickens in the diseased group with an RV:TV ratio in the range of 0.250 to 0.299 (10%) was significantly higher (25 to 30%) compared to that of the other groups (P < 0.05), and the proportion in all chickens was 28%. In addition, the IL-6, IL-1beta, NF-kappaB, and P38 protein concentrations were higher in the diseased group, whereas there were no differences between the control group and the protected group. Moreover, the measurements of body weight, liver function, kidney function and electrolytes showed significant differences between the diseased group and the other groups. These findings suggest that tanshinone IIA may protect broilers from PAH, which is an important piece of information for the poultry industry.

AB - The aim of this study was to determine the antimicrobial resistance of E. faecalis and E. faecium strains isolated from poultry and to carry out genotypic characterization thereof with the ADSRRS-fingerprinting method (amplification of DNA fragments surrounding rare restriction sites) and analysis of the genetic relatedness between the isolates with different resistance and virulence determinants. Samples were collected from 70 4-week-old chickens and tested for Enterococcus. Minimum inhibitory concentrations of 11 antimicrobials were determined using the broth microdilution method. Detection of antibiotic resistance and virulence genes was performed using PCR, and molecular analysis was carried out using the ADSRRS-fingerprinting method. The highest percentage of strains was resistant to tetracycline (60.5%) and erythromycin (54.4%), and a large number exhibited high-level resistance to both kanamycin (42.1%) and streptomycin (34.2%). Among 8 genes encoding AME, the tested strains showed mainly the presence of [aph(3?)-IIIa], [ant(6)-Ia], [aac(6?)-Ie-aph(2??)-Ia], and [ant(9)-Ia] genes. Phenotypic resistance to erythromycin was encoded in 98.4% strains by the ermB gene. Genotypic resistance to tetracycline in E. faecium was associated with the presence of tetM and tetL (respectively, in 95.5 and 57.7% of the isolates); in contrast, E. faecalis strains were characterized mainly by the presence of tetO (83.3%). The virulence profile was homogenous for all E. faecium strains and included only efaAfm and ccf genes. All E. faecalis strains exhibited efaAfs, gelE, and genes encoding sex pheromones. The strains tested exhibited 34 genotypic profiles. Comparative analysis of phenotypic and genotypic resistance and virulence profiles and confrontation thereof with the genotypes of the strains tested showed that strains assigned to a particular genotype have an identical phenotypic resistance profile and a panel of resistance and virulence genes. The results of this study confirm that poultry can be a reservoir of resistant E. faecium and E. faecalis strains with multiple combinations of resistance and virulence genes, whose specific panel determines not only phenotypic characteristics but also has a strong correlation with the genotypic profiles of the strains. PMID- 27702916 TI - Evaluation of the efficacy of chitosan nanoparticles loaded PhiKAZ14 bacteriophage in the biological control of colibacillosis in chickens. AB - Disease inflicted by avian pathogenic Escherichia coli (APEC) causes economic losses and burden to the poultry industry worldwide. In this study, the efficacy of chitosan nanoparticles loaded PhiKAZ14 (C-PhiKAZ14 NPs) as an oral biological therapy for Colibacillosis was evaluated. C-PhiKAZ14 NPs containing 107 PFU/ml of PhiKAZ14 (Myoviridae; T4-like coliphage) bacteriophage were used to treat experimentally APEC-infected COBB 500 broiler chicks. C-PhiKAZ14 NPs and PhiKAZ14 bacteriophage were administered orally in a single dose. The clinical symptoms, mortality, and pathology in the infected birds were recorded and compared with those of control birds that did not receive C-PhiKAZ14 NPs or naked PhiKAZ14 bacteriophage. The results showed that C-PhiKAZ14 NP intervention decreased mortality from 58.33 to 16.7% with an increase in the protection rate from 42.00 to 83.33%. The bacterial colonization of the intestines of infected birds was significantly higher in the untreated control than in the C-PhiKAZ14 NP-treated group (2.30*109 +/- 0.02 and 0.79*103 +/- 0.10 CFU/mL, respectively) (P <= 0.05). Similarly, a significant difference in the fecal shedding of Escherichia coli was observed on d 7 post challenge between the untreated control and the C-PhiKAZ14 NP-treated group (2.35*109 +/- 0.05 and 1.58*103 +/- 0.06 CFU/mL, respectively) (P <= 0.05). Similar trends were observed from d 14 until d 21 when the experiment was terminated. Treatment with C-PhiKAZ14 NPs improved the body weights of the infected chicks. A difference in body weight on d 7 post challenge was observed between the untreated control and the C-PhiKAZ14 NP-treated group (140 +/- 20 g and 160 +/- 20 g, respectively). The increase was significant (P <= 0.05) on d 21 between the 2 groups (240 +/- 30 g and 600 +/- 80 g, respectively). Consequently, the clinical signs and symptoms were ameliorated upon treatment with C-PhiKAZ14 NPs compared with infected untreated birds. In all, based on the results, it can be concluded that the encapsulation of bacteriophage could enhance bacteriophage therapy and is a valuable approach for controlling APEC infections in poultry. PMID- 27702917 TI - Colonization of internal organs by Salmonella serovars Heidelberg and Typhimurium in experimentally infected laying hens housed in enriched colony cages at different stocking densities. AB - Contaminated eggs produced by infected commercial laying flocks are often implicated as sources of human infections with Salmonella Enteritidis, but Salmonella serovars Heidelberg and Typhimurium have also been associated with egg transmitted illness. Contamination of the edible contents of eggs is a consequence of the colonization of reproductive tissues in systemically infected hens. In recent years, the animal welfare implications of diverse poultry housing and management systems have been vigorously debated, but the food safety significance of laying hen housing remains uncertain. The present study evaluated the effects of 2 different bird stocking densities on the invasion of internal organs by Salmonella serovars Heidelberg and Typhimurium in groups of experimentally infected laying hens housed in colony cages enriched with perching and nesting areas. Laying hens were distributed at 2 different stocking densities (648 and 973 cm2/bird) into colony cages and (along with a group housed in conventional cages at 648 cm2/bird) orally inoculated with doses of 107 cfu of 2 strain cocktails of either Salmonella Heidelberg or Salmonella Typhimurium. At 5 to 6 d post-inoculation, hens were euthanized and samples of internal organs (cecum, liver, spleen, ovary, and oviduct) were removed for bacteriologic culturing. The overall frequency of Salmonella isolation from ceca after inoculation with strains of serovar Heidelberg (83.3%) was significantly (P < 0.001) greater than the corresponding value for strains of serovar Typhimurium (53.8%), whereas Salmonella was recovered significantly more often from both livers (85.2% vs. 53.7%; P < 0.0001) and spleens (78.7% vs. 56.5%; P = 0.0008) after inoculation with strains of serovar Typhimurium than strains of serovar Heidelberg. However, there were no significant differences (P > 0.05) between stocking densities or cage systems in the frequencies of isolation of either Salmonella serovar from any of the five sampled tissues. These results contrast with prior studies, which reported increased susceptibility to internal organ invasion by Salmonella Enteritidis among hens in conventional cages at higher stocking densities. PMID- 27702918 TI - Effects of low-protein diets on growth performance and carcass yields of growing French meat quails (France coturnix coturnix). AB - A dose-response experiment with 5 analyzed dietary crude protein (CP) levels (17.61, 19.73, 21.58, 23.24, and 25.32%) was conducted to investigate the effects of low-protein diets on growth performance and carcass yields of French meat quails from 15 to 42 d of age. All diets were formulated to contain a similar dietary energy level and amino acid profile. A total of 400 fifteen-day-old French quails were divided into 5 experimental treatments and each treatment contained 4 replicate pens of 20 birds (10?+10?). At 42 d of age, weight gain, feed intake, CP intake, feed/gain, and the yields of breast part with bone, leg part with bone, and liver of quails from each pen were measured. The results showed significant effects of the low-CP diets on CP intake, weight gain, feed intake, and feed/gain at different experiment periods except for the sixth wk of age (P < 0.05). In addition, as dietary CP decreased from 25.32 to 17.61%, feed intake and feed/gain were increased linearly (P < 0.05), whereas CP intake showed the opposite trend and decreased gradually. On the other hand, the carcass yields of quail were not influenced by reducing dietary CP at 42 day of age (P > 0.05). Based on broken-line regression, 23.0%, 22.5%, and 20.4% were the minimum dietary CP to keep weight gain similar to the quails fed with 25.32% CP diets during the third, fourth, and fifth wk of age, respectively. In summary, with crystalline amino acid supplementation based on a similar amino acid profile, it was possible to formulate the low-protein diets containing about 22.0% CP for growing meat quails without adverse effects on growth and carcass yields of meat quails. PMID- 27702919 TI - Effect of climatic elements on Campylobacter colonization in broiler flocks reared in southern Japan from 2008 to 2012. AB - To demonstrate the effect of climatic elements on Campylobacter colonization in broiler chickens reared in Japan, the correlation between Campylobacter isolated from chickens (191 of 236 flocks, 80.9%) between 2008 and 2012 and climatic elements was analyzed by logistic regression. We divided the rearing process into 13 terms of 5 d each (total: 65 d). Terms were numbered backwards, wherein a 0 term lag was considered as the sampling day plus 4 d before sampling; 1-term lag was the 5-d term before the 0-term lag, and so on, until the 12-term lag. We obtained climatic data tracing back from the 0-term to the 12-term lags. For evaluation in each season, we divided chickens reared during periods of rising temperature (spring, summer) and decreasing temperature (autumn, winter). Air temperature showed a positive correlation with Campylobacter colonization from the 0- to 12-term lags in chickens reared during the period of rising temperature (odds ratio [OR], 1.069 to 1.104), and from the 0- to 4- and 6-term lags (OR, 1.079 to 1.105) in chickens reared during the period of decreasing temperature. The strong positive effect of air temperature on Campylobacter colonization, particularly during the period of rising temperature, may be associated with the effect on the Campylobacter environmental sources and/or vectors. A positive correlation was observed between Campylobacter colonization and humidity when chicken houses were empty and new chicks were introduced (from the 9- to 12-term lags) during the period of decreasing temperature (OR, 1.076 to 1.141). Thus, high humidity would be an important factor causing carry-over of Campylobacter infection during the period of decreasing temperature. We also found that solar radiation increased Campylobacter colonization during the period of decreasing temperature, from the 2- to 8-term lags, except for the 4- and 5-term lags, in Japan. The results of this study demonstrate the effects of air temperature, humidity, and solar radiation on Campylobacter colonization in broiler chickens, and are potentially important for developing strategies to reduce the risk of Campylobacter contamination in broiler chickens. PMID- 27702920 TI - Effects of betaine on biological functions in meat-type ducks exposed to heat stress. AB - Heat stress in hot seasons is a major problem in poultry production, particularly in humid areas. The aim of this study was to determine the pharmacodynamics of betaine on the blood and cecal short chain fatty acid profile in meat-type ducks exposed to heat stress. Three-hundred-sixty meat-type ducks (Anas platyrhynchos domesticus) were randomly allocated into 4 treatments: C (heat stress control without betaine), T1 (700 ppm betaine), T2 (1,000 ppm betaine), and T3 (1,300 ppm betaine). Each treatment had 6 replicated pens with 15 meat-type ducks per pen. The study was conducted for 42 days. Our findings revealed that the betaine group had higher body weight gain compared to the control group under heat stress (P < 0.05). Betaine supplementation resulted in more significant improvement in hematological indicators such as RBCs and platelet counts than the heat stress control group (P < 0.05). Under the heat-wave environment, supplementation of betaine manifested a significant decrease in blood pH (P < 0.05) but not in electrolytes (Na+, K+ and Cl-) and gas concentration. The concentration of short chain fatty acids (SCFA) in the cecum was higher than the control under heat stress conditions. The total SCFA, acetic acid, and propionic acid production was higher in the betaine supplemented groups compared to the heat stress control group (P < 0.05). Results showed that betaine supplementation has beneficial effects in meat-type ducks under heat stress on short chain fatty acid levels, blood biochemical parameters, and body weight. PMID- 27702921 TI - Estimation of the maximum safe level of feed ingredients by spline or broken-line nonlinear regression models. AB - The use of non-linear regression models in the analysis of biological data has led to advances in poultry nutrition. Spline or broken-line nonlinear regression models are commonly used to estimate nutritional requirements. One particular application of broken-line models is estimating the maximum safe level (MSL) of feed ingredients beyond which the ingredients become toxic, resulting in reduced performance. The objectives of this study were to evaluate the effectiveness of broken-line models (broken-line linear or BLL; and broken-line quadratic or BLQ) in estimating the MSL; to identify the most efficient design of feeding trials by finding the optimal number of ingredient levels and replications; and to re estimate the MSL of various test ingredients reported in the nutrition literature for comparison purposes. The Maximum Ingredient level Optimization Workbook (MIOW) was developed to simulate a series of experiments and estimate the MSL and the corresponding descriptive statistics (SD, SE, CI, and R2). The results showed that the broken-line models provided good estimates of the MSL (small SE and high R2) with the BLL model producing higher MSL values as compared to the BLQ model. Increasing the number of experimental replications or ingredient levels (independently of each other) reduced the SE of the MSL with diminishing returns. The SE of the MSL was reduced with increasing the size (total pens) of the simulated experiments by increasing either the number of replications or levels or both. The evaluation of MSLs reported in the existing literature revealed that the multiple range procedure used to determine the MSL in several reports can both overestimate and underestimate the MSL compared to the results obtained by the broken-line models. The results suggest that the broken-line linear models can be used in lieu of the multiple range test to estimate the MSL of feed ingredients along with the corresponding descriptive statistics, such as the SE of the MSL. PMID- 27702922 TI - Broiler chickens dead on arrival: associated risk factors and welfare indicators. AB - The pre-slaughter phase of the production process has potentially important animal welfare implications, including mortality (recorded as "Dead on Arrivals"; DOA: ). To reduce DOA%, specific risk factors need to be identified. DOA% can also be used as a first and quick screening of pre-slaughter broiler welfare under commercial conditions. The aim of the present study was to identify risk factors for DOA% in commercial broiler flocks and to find associations between DOA% and animal-based indicators of broiler welfare during the pre-slaughter phase. Eighty-one transported flocks to five slaughter plants were assessed. Farmers provided information on the flock and observers gathered data on pre slaughter factors. DOA% was recorded by slaughter plant personnel. The association between risk factors and DOA% was tested using linear mixed models, with slaughter plant as the random effect. Mean (+/- SE) DOA% was 0.30 +/- 0.05% and median was 0.19% (range 0.04 to 3.34%). Two risk factors for DOA% were identified, both related to flock health status during the production phase. Higher DOA% was found when farmers did not check chick quality upon arrival (P = 0.011), although one extreme DOA% caused this significant effect. In addition, on farm mortality during production (including selective culling) was negatively associated with DOA% (P = 0.011), potentially due to the selective culling on farm. Further research is needed on the impact of on-farm health status on welfare during the pre-slaughter phase, as the current study provided some evidence that on-farm factors are linked to mortality during the pre-slaughter phase. No specific characteristics of the pre-slaughter phase could be identified as risk factor for increased mortality. DOA% was positively associated with five welfare indicators, including indicators of thermal stress, which indicates the potential to use DOA% as a quick, cost-efficient screening tool for those welfare aspects. PMID- 27702923 TI - Impact of the separate pre-slaughter stages on broiler chicken welfare. AB - Before broilers are slaughtered, several parties are involved in catching, loading, transportation and lairage. During these pre-slaughter activities, broilers are exposed to a variety of stressors. A detailed understanding of how broiler welfare is impaired during each stage could help the responsible parties to make targeted improvements. The aim of this study was to identify welfare problems occurring during the consecutive stages of commercial broiler transportation and to identify risk factors associated with the identified welfare problems. Commercial Belgian transports (n = 81) were assessed in spring (n = 14), summer (n = 33), autumn (n = 10), and winter (n = 24), and potential risk factors were recorded by the observer. Animal-based welfare indicators were scored before the start of the pre-slaughter phase as well as after the catching, transport and lairage, and slaughter stages to assess the impact of each stage. The most frequently observed welfare impairments were vent and thigh lesions, panting, wing fractures, and bruising on wings and breasts. Our results show that the impact of the pre-slaughter phase on broiler welfare is multifaceted. The overall pre-slaughter phase resulted in a mean weight decrease of 5.3%, a prevalence of 1.4% in leg bruising, and 3.7% in breast or wing bruising. Wing fractures occurred mainly during the catching stage: Prevalence increased from 0.1% to 1.9% (P = 0.003). A welfare comparison before and after transportation and lairage revealed that plumage had become more soiled (P = 0.003), body temperature decreased by 0.7 degrees C (P < 0.001), huddling prevalence increased by 0.5% (P = 0.008), prevalence of birds with splayed legs increased by 0.08% (P = 0.008), prevalence of supine birds decreased by 0.05% (P = 0.003), and 0.1% fewer birds with wings stuck in the crates (P = 0.010) were observed. Risk factor analyses revealed that carefully choosing the catching crew, minimizing thermal stress, reducing duration of transportation, and worker training are promising actions that may improve broiler welfare during the pre-slaughter phase. PMID- 27702924 TI - Effect of acute heat stress and slaughter processing on poultry meat quality and postmortem carbohydrate metabolism. AB - This study investigated the effects of acute heat stress and slaughter processing on poultry meat quality and carbohydrate metabolism. Broilers (200) were randomly divided into 2 groups receiving heat stress (HS; 36 degrees C for one h), compared to a non-stressed control (C). At slaughter, each group was further divided into 2 groups for slaughter processing (L = laboratory; F = commercial factory). L group breasts were removed immediately after bleeding without carcass scalding or defeathering, and stored at 4 degrees C. F group broilers were scalded (60 degrees C, 45 s) after bleeding and defeathering. Then the breasts were removed and cooled in ice water until the core temperature was <=4 degrees C. Rates of Pectoralis core temperature and pH decline were changed by slaughter processing, but only HS affected ultimate pH in group L. HS muscles had higher L* values (P < 0.05) than controls at 24 h postmortem. Laboratory processing "hot deboning" increased drip loss, which resulted in a lower cooked loss (P < 0.05). Postmortem glycolysis was affected only by HS. The speed of lactic acid accumulation and glycogen degradation was faster in the HS group than controls at 5 min postmortem. During storage the glycolysis rates were not different (P > 0.05). Sarcoplasmic protein solubility was higher in F processed birds (P < 0.05). HS decreased the solubility of myofibrillar and total protein in the L slaughtered birds. Thus, HS caused a higher frequency of accelerated muscle glycolysis than controls. Factory processing (chilling) could not completely eliminate the effects of accelerated glycolysis caused by pre-slaughter HS. PMID- 27702925 TI - Distribution of Campylobacter jejuni multilocus sequence types isolated from chickens in Poland. AB - Poultry is recognized as the most important source of food-related transmission of Campylobacter jejuni to humans and campylobacteriosis is the most commonly reported zoonotic bacterial disease in the European Union. It has been documented that C. jejuni is genetically diverse and analyses of bacterial isolates usually show a large strain variety. Therefore, molecular typing of strains represents an important tool to study the genetic diversity of isolates and to trace individual strains that cause human infections. The aim of the study was characterization of genetic population structure and antimicrobial resistance (AMR) of C. jejuni isolated from Polish chickens. C. jejuni from chicken ceca and the corresponding carcasses (72 and 61 strains, respectively), originating from 128 flocks in Poland during February 2011 and May 2013, were used in the study. The isolates were tested for their population structure and genetic diversity using a multilocus sequence typing (MLST) scheme with connection to their antimicrobial resistance. The molecular analysis of 133 C. jejuni generated 39 different sequence types (ST); 3 of them were defined for the first time. Additionally, 16 STs were represented by single isolates. The most common STs observed were 6411 (16.5% isolates) and 257 (15.0% strains). The first mentioned ST was resistant to 3 different classes of antibiotics, i.e., quinolones, tetracyclines, and aminoglycosides. Overall, 125 (94.4%) of C. jejuni isolates demonstrated antimicrobial resistance and the most frequent AMR profile observed was ciprofloxacin, nalidixic acid, tetracycline (47.4% strains). Likewise, the clonal complexes CC 257 and CC 353 were defined as the predominant molecular groups covering altogether 37 C. jejuni strains. No associations between CCs and the origin of the samples as well as the place of isolation were found. This study highlights that the C. jejuni population from chickens in Poland was diverse and showed a weak clonal structure.

AB - In 1976 an infant boy initially presented with a choroidal vein of Galen malformation (cVOGM). Craniotomy and clipping of the anterior cerebral artery and posterior choroidal arteries was performed, which was reported in the literature 40 years ago. The patient remained asymptomatic until age 42 when he re-presented with an isolated intraventricular hemorrhage. Angiography demonstrated cVOGM with venous sinus occlusive disease leading to venous hypertension and subsequent intraventricular hemorrhage. The angiogram also demonstrated a 'pseudo-nidus' composed of multiple arterial-to-arterial anastomoses that had developed as a result of the original surgical treatment. We embolized a portion of the lesion to reduce the venous hypertension. The patient has been asymptomatic for more than 2 years. To our knowledge, this is the first reported case of a symptomatic neonatal VOGM treated with open surgery that required embolization as an adult for a delayed hemorrhagic presentation.

AB - Optic neuritis (ON) is an acquired disorder of the optic nerve due to inflammation, demyelination or degeneration. We report a child who presented with acute onset bilateral visual loss who, following a diagnosis of ON, was treated and had excellent visual recovery. Paediatric ON is considered to be different clinical entity to adult ON. Although in children ON is usually parainfectious or postinfectious, it can be the first presenting feature of multiple sclerosis or neuromyelitis optica spectrum disease. In this paper, we discuss the literature on treatment of ON and prediction of risk of recurrence. PMID- 27702929 TI - Aortic valve replacement for Libman-Sacks endocarditis. AB - A 24-year-old man with systemic lupus erythematosus and antiphospholipid syndrome complicated by lupus nephritis presented with acute limb ischaemia secondary to an embolus. Following embolectomy, the patient underwent a transthoracic echocardiogram which revealed a large vegetation on all three cusps of the aortic valve. The patient was taken for an urgent aortic valve replacement with a mechanical valve. Cultures of one cusp remained sterile. Histopathological examination of the remaining two cusps revealed sterile fibrin-rich thrombotic vegetations characteristic of non-bacterial thrombotic endocarditis. PMID- 27702930 TI - Triple threat in pregnancy. AB - A woman aged 22 years with a history of lupus presented in the 18th week of pregnancy with hypertensive emergency and flash pulmonary oedema. Bedside echocardiogram revealed severe left ventricular (LV) dysfunction with an ejection fraction (EF) of 25% and pericardial effusion. Laboratories revealed hypocomplementemia, proteinuria, elevated C reactive protein and anti-DS-DNA, raising concern for a lupus flare. Cardiac MRI showed an acute intramyocardial oedematous process, consistent with lupus carditis, and further worsening of LVEF to 13%. Shared-decision-making with the patient included discussion of maternal risks of continuation of pregnancy in the setting of worsening heart function and the fetal risks of definitive treatment with cyclophosphamide for a lupus flare and the patient decided to proceed with medical termination of pregnancy. Treatment with immunosuppressants, including cyclophosphamide, and steroids, was then initiated. 2 months after discharge, cardiac MRI showed marked improvement in LVEF to 50% and the patient remains clinically free of heart failure.

AB - We describe 2 paediatric patients who developed large orbital conjunctival epithelium-lined inclusion cysts postsurgery. Case 1 underwent Ahmed glaucoma valve implant surgery 8 months ago and case 2 underwent strabismus surgery 7 years ago. Both cases had either symptomatic strabismus or a mass causing some degree of proptosis or incomitance due to lesions in the intraorbital space. Following total excision of the cysts all associated symptoms were resolved. Conjunctival cysts following ocular surgery can develop anywhere in the anterior segment; however, large orbital cysts following anterior segment surgery are quite rare. We think that implantation cysts should be considered in the differential diagnosis of patients that have signs of orbital mass with a history of previous anterior segment surgery. Complete excision of the cysts results in resolution of all associated signs and symptoms. PMID- 27702933 TI - Erdheim-Chester disease: 25-year history with early CNS involvement.

The case is a timely reminder of the presenting features of the condition, given the emergence of potential new treatment options. PMID- 27702934 TI - Efficacy of extracorporeal ultrafiltration in patients with diuretic-resistant heart failure. AB - Renal congestion contributes to the cardiorenal syndrome. There are some heart failure cases that are refractory to diuretic therapy. If the dose of diuretics is titrated, it leads to irreversible renal dysfunction. Early administration of tolvaptan is effective in treating fluid retention and congestion. However, in case of tolvaptan resistance, starting extracorporeal ultrafiltration (ECUM) at an early stage should be considered. Tolvaptan has been proven efficient, and we believe it should be incorporated with the classical method, ECUM. Herein, we present a case of successful application of ECUM to a heart failure patient refractory to any diuretics and tolvaptan.

AB - Mesothelioma is an uncommon malignant neoplasm and a localised form of the pleura is especially very rare. Diagnosis of localised malignant pleural mesothelioma (LMPM) is very challenging. Histopathological verification is the gold standard, and studies such as CT, positron emission tomography (PET) and thoracoscopy are very valuable tools in assisting diagnosis. We report a case of histopathologically proven LMPM, which was discovered as a well circumscribed solitary subpleural nodule on PET-CT after presentation with cranial metastasis. This case shows that LMPM can present with uncommon radiological and clinical appearances, and imaging tools such as PET-CT have a very important role in diagnosis.

AB - A consecutive group of 250 patients underwent medico-legal assessment at a mean of 24 (+/-13) months following upper limb injuries. Each had completed questionnaires to assess function (Quick-DASH) and cold intolerance (CIQ36) before clinical assessment following which their whole limb impairment percentage was calculated. The mean(+/-SD) whole limb impairment, QDASH and CIQ36 scores were 9(+/-14)%, 43(+/-24) and 17(+/-10), respectively. There was a significant correlation between whole limb impairment and QDASH, although some patients reported surprisingly high disability levels despite minimal or no objective functional impairment. Whilst useful qualitative information can be obtained from questionnaires, the correlation between subjective and objective scores is weak albeit statistically significant. Individual patients can show marked discrepancies between objective and subjective functional scores. The results of questionnaires in individual medico-legal patients should be treated with caution. PMID- 27702938 TI - Illicit Fentanyl-Related Fatalities in Florida: Toxicological Findings. AB - Fentanyl induces pharmacological effects and abuse liability comparable to other prescription opioids and heroin. A surge in fentanyl-related fatalities has been periodically reported throughout the USA. The University of Florida Forensic Toxicology Laboratory observed a significant increase in fentanyl-related deaths starting in mid-2014. The present report evaluated toxicological findings, demographics of the decedents and circumstances of death in the postmortem cases that were submitted to the laboratory for toxicological analysis from July 2014 to January 2015 and that were tested for fentanyl in biological specimens. The cases originated from 6 of the 24 Florida Medical Examiner Districts, with the majority from District 12 (Desoto, Manatee and Sarasota counties). The specimens were analyzed for fentanyl by gas chromatography-mass spectrometry; the limit of detection (LOD) was 0.62 ng/mL and the limit of quantification (LOQ) was 2.5 ng/mL. During the 7-month period, the laboratory tested 143 postmortem cases for fentanyl and 50% had quantifiable fentanyl in postmortem blood. Fentanyl concentrations ranged from 2.5 to 68 ng/mL (n = 66; median: 9.8 ng/mL); six cases were positive for fentanyl >LOD but 99% identity on the amino acid level), the promoter regions are significantly different. By expression in Arabidopsis as a heterologous system, we show that the allele from the wild Chinese grapevine can confer accumulation of stilbenes and resistance against the powdery mildew Golovinomyces cichoracearum, whereas the allele from the vinifera cultivar cannot. To dissect the upstream signalling driving the activation of this promoter, we used a dual-luciferase reporter system in a grapevine cell culture. We show elevated responsiveness of the promoter from the wild grape to salicylic acid (SA) and to the pathogen-associated molecular pattern (PAMP) flg22, equal induction of both alleles by jasmonic acid (JA), and a lack of response to the cell death-inducing elicitor Harpin. This elevated SA response of the VpSTS promoter depends on calcium influx, oxidative burst by RboH, mitogen-activated protein kinase (MAPK) signalling, and JA synthesis. We integrate the data in the context of a model where the resistance of V. pseudoreticulata is linked to a more efficient recruitment of SA signalling for phytoalexin synthesis. PMID- 27702995 TI - A rhamnose-deficient lipopolysaccharide mutant of Rhizobium sp. IRBG74 is defective in root colonization and beneficial interactions with its flooding tolerant hosts Sesbania cannabina and wetland rice. AB - Rhizobium sp. IRBG74 develops a classical nitrogen-fixing symbiosis with the aquatic legume Sesbania cannabina (Retz.). It also promotes the growth of wetland rice (Oryza sativa L.), but little is known about the rhizobial determinants important for these interactions. In this study, we analyzed the colonization of S. cannabina and rice using a strain of Rhizobium sp. IRBG74 dually marked with beta-glucuronidase and the green fluorescent protein. This bacterium colonized S. cannabina by crack entry and through root hair infection under flooded and non flooded conditions, respectively. Rhizobium sp. IRBG74 colonized the surfaces of wetland rice roots, but also entered them at the base of lateral roots. It became endophytically established within intercellular spaces in the rice cortex, and intracellularly within epidermal and hypodermal cells. A mutant of Rhizobium sp. IRBG74 altered in the synthesis of the rhamnose-containing O-antigen exhibited significant defects, not only in nodulation and symbiotic nitrogen fixation with S. cannabina, but also in rice colonization and plant growth promotion. Supplementation with purified lipopolysaccharides from the wild-type strain, but not from the mutant, restored the beneficial colonization of rice roots, but not fully effective nodulation of S. cannabina Commonalities and differences in the rhizobial colonization of the roots of wetland legume and rice hosts are discussed. PMID- 27702994 TI - The build-up of osmotic stress responses within the growing root apex using kinematics and RNA-sequencing. AB - Molecular regulation of growth must include spatial and temporal coupling of cell production and cell expansion. The underlying mechanisms, especially under environmental challenge, remain obscure. Spatial patterns of cell processes make the root apex well suited to deciphering stress signaling pathways, and to investigating both processes. Kinematics and RNA-sequencing were used to analyze the immediate growth response of hydroponically grown Populus nigra cuttings submitted to osmotic stress. About 7400 genes and unannotated transcriptionally active regions were differentially expressed between the division and elongation zones. Following the onset of stress, growth decreased sharply, probably due to mechanical effects, before recovering partially. Stress impaired cell expansion over the apex, progressively shortened the elongation zone, and reduced the cell production rate. Changes in gene expression revealed that growth reduction was mediated by a shift in hormone homeostasis. Osmotic stress rapidly elicited auxin, ethylene, and abscisic acid. When growth restabilized, transcriptome remodeling became complex and zone specific, with the deployment of hormone signaling cascades, transcriptional regulators, and stress-responsive genes. Most transcriptional regulations fit growth reduction, but stress also promoted expression of some growth effectors, including aquaporins and expansins Together, osmotic stress interfered with growth by activating regulatory proteins rather than by repressing the machinery of expansive growth. PMID- 27702996 TI - Effects of reduced carbonic anhydrase activity on CO2 assimilation rates in Setaria viridis: a transgenic analysis. AB - In C4 species, the major beta-carbonic anhydrase (beta-CA) localized in the mesophyll cytosol catalyses the hydration of CO2 to HCO3-, which phosphoenolpyruvate carboxylase uses in the first step of C4 photosynthesis. To address the role of CA in C4 photosynthesis, we generated transgenic Setaria viridis depleted in beta-CA. Independent lines were identified with as little as 13% of wild-type CA. No photosynthetic defect was observed in the transformed lines at ambient CO2 partial pressure (pCO2). At low pCO2, a strong correlation between CO2 assimilation rates and CA hydration rates was observed. C18O16O isotope discrimination was used to estimate the mesophyll conductance to CO2 diffusion from the intercellular air space to the mesophyll cytosol (gm) in control plants, which allowed us to calculate CA activities in the mesophyll cytosol (Cm). This revealed a strong relationship between the initial slope of the response of the CO2 assimilation rate to cytosolic pCO2 (ACm) and cytosolic CA activity. However, the relationship between the initial slope of the response of CO2 assimilation to intercellular pCO2 (ACi) and cytosolic CA activity was curvilinear. This indicated that in S. viridis, mesophyll conductance may be a contributing limiting factor alongside CA activity to CO2 assimilation rates at low pCO2. PMID- 27702997 TI - Dynamic changes of small RNAs in rice spikelet development reveal specialized reproductive phasiRNA pathways. AB - Dissection of the genetic pathways and mechanisms by which anther development occurs in grasses is crucial for both a basic understanding of plant development and for examining traits of agronomic importance such as male sterility. In rice, MULTIPLE SPOROCYTES1 (MSP1), a leucine-rich-repeat receptor kinase, plays an important role in anther development by limiting the number of sporocytes. OsTDL1a (a TPD1-like gene in rice) encodes a small protein that acts as a cofactor of MSP1 in the same regulatory pathway. In this study, we analyzed small RNA and mRNA changes in different stages of spikelets from wild-type rice, and from msp1 and ostdl1a mutants. Analysis of the small RNA data identified miRNAs demonstrating differential abundances. miR2275 was depleted in the two rice mutants; this miRNA is specifically enriched in anthers and functions to trigger the production of 24-nt phased secondary siRNAs (phasiRNAs) from PHAS loci. We observed that the 24-nt phasiRNAs as well as their precursor PHAS mRNAs were also depleted in the two mutants. An analysis of co-expression identified three Argonaute-encoding genes (OsAGO1d, OsAGO2b, and OsAGO18) that accumulate transcripts coordinately with phasiRNAs, suggesting a functional relationship. By mRNA in situ analysis, we demonstrated a strong correlation between the spatiotemporal pattern of these OsAGO transcripts and phasiRNA accumulations. PMID- 27702998 TI - Identification of Neutrophil Exocytosis Inhibitors (Nexinhibs), Small Molecule Inhibitors of Neutrophil Exocytosis and Inflammation: DRUGGABILITY OF THE SMALL GTPase Rab27a. AB - Neutrophils constitute the first line of cellular defense in response to bacterial and fungal infections and rely on granular proteins to kill microorganisms, but uncontrolled secretion of neutrophil cargos is injurious to the host and should be closely regulated. Thus, increased plasma levels of neutrophil secretory proteins, including myeloperoxidase and elastase, are associated with tissue damage and are hallmarks of systemic inflammation. Here, we describe a novel high-throughput screening approach to identify small molecule inhibitors of the interaction between the small GTPase Rab27a and its effector JFC1, two central regulators of neutrophil exocytosis. Using this assay, we have identified small molecule inhibitors of Rab27a-JFC1 binding that were also active in cell-based neutrophil-specific exocytosis assays, demonstrating the druggability of Rab GTPases and their effectors. These compounds, named Nexinhibs (neutrophil exocytosis inhibitors), inhibit exocytosis of azurophilic granules in human neutrophils without affecting other important innate immune responses, including phagocytosis and neutrophil extracellular trap production. Furthermore, the compounds are reversible and potent inhibitors of the extracellular production of superoxide anion by preventing the up-regulation of the granule membrane-associated subunit of the NADPH oxidase at the plasma membrane. Nexinhibs also inhibit the up-regulation of activation signature molecules, including the adhesion molecules CD11b and CD66b. Importantly, by using a mouse model of endotoxin-induced systemic inflammation, we show that these inhibitors have significant activity in vivo manifested by decreased plasma levels of neutrophil secretory proteins and significantly decreased tissue infiltration by inflammatory neutrophils. Altogether, our data present the first neutrophil exocytosis-specific inhibitor with in vivo anti-inflammatory activity, supporting its potential use as an inhibitor of systemic inflammation. PMID- 27702999 TI - Ohgata, the Single Drosophila Ortholog of Human Cereblon, Regulates Insulin Signaling-dependent Organismic Growth. AB - Cereblon (CRBN) is a substrate receptor of the E3 ubiquitin ligase complex that is highly conserved in animals and plants. CRBN proteins have been implicated in various biological processes such as development, metabolism, learning, and memory formation, and their impairment has been linked to autosomal recessive non syndromic intellectual disability and cancer. Furthermore, human CRBN was identified as the primary target of thalidomide teratogenicity. Data on functional analysis of CRBN family members in vivo, however, are still scarce. Here we identify Ohgata (OHGT), the Drosophila ortholog of CRBN, as a regulator of insulin signaling-mediated growth. Using ohgt mutants that we generated by targeted mutagenesis, we show that its loss results in increased body weight and organ size without changes of the body proportions. We demonstrate that ohgt knockdown in the fat body, an organ analogous to mammalian liver and adipose tissue, phenocopies the growth phenotypes. We further show that overgrowth is due to an elevation of insulin signaling in ohgt mutants and to the down-regulation of inhibitory cofactors of circulating Drosophila insulin-like peptides (DILPs), named acid-labile subunit and imaginal morphogenesis protein-late 2. The two inhibitory proteins were previously shown to be components of a heterotrimeric complex with growth-promoting DILP2 and DILP5. Our study reveals OHGT as a novel regulator of insulin-dependent organismic growth in Drosophila. PMID- 27703000 TI - Palmitoylation of Desmoglein 2 Is a Regulator of Assembly Dynamics and Protein Turnover. AB - Desmosomes are prominent adhesive junctions present between many epithelial cells as well as cardiomyocytes. The mechanisms controlling desmosome assembly and remodeling in epithelial and cardiac tissue are poorly understood. We recently identified protein palmitoylation as a mechanism regulating desmosome dynamics. In this study, we have focused on the palmitoylation of the desmosomal cadherin desmoglein-2 (Dsg2) and characterized the role that palmitoylation of Dsg2 plays in its localization and stability in cultured cells. We identified two cysteine residues in the juxtamembrane (intracellular anchor) domain of Dsg2 that, when mutated, eliminate its palmitoylation. These cysteine residues are conserved in all four desmoglein family members. Although mutant Dsg2 localizes to endogenous desmosomes, there is a significant delay in its incorporation into junctions, and the mutant is also present in a cytoplasmic pool. Triton X-100 solubility assays demonstrate that mutant Dsg2 is more soluble than wild-type protein. Interestingly, trafficking of the mutant Dsg2 to the cell surface was delayed, and a pool of the non-palmitoylated Dsg2 co-localized with lysosomal markers. Taken together, these data suggest that palmitoylation of Dsg2 regulates protein transport to the plasma membrane. Modulation of the palmitoylation status of desmosomal cadherins can affect desmosome dynamics. PMID- 27703001 TI - Different DNA End Configurations Dictate Which NHEJ Components Are Most Important for Joining Efficiency. AB - The nonhomologous DNA end-joining (NHEJ) pathway is a key mechanism for repairing dsDNA breaks that occur often in eukaryotic cells. In the simplest model, these breaks are first recognized by Ku, which then interacts with other NHEJ proteins to improve their affinity at DNA ends. These include DNA-PKcs and Artemis for trimming the DNA ends; DNA polymerase MU and lambda to add nucleotides; and the DNA ligase IV complex to ligate the ends with the additional factors, XRCC4 (X ray repair cross-complementing protein 4), XLF (XRCC4-like factor/Cernunos), and PAXX (paralog of XRCC4 and XLF). In vivo studies have demonstrated the degrees of importance of these NHEJ proteins in the mechanism of repair of dsDNA breaks, but interpretations can be confounded by other cellular processes. In vitro studies with NHEJ proteins have been performed to evaluate the nucleolytic resection, polymerization, and ligation steps, but a complete system has been elusive. Here we have developed a NHEJ reconstitution system that includes the nuclease, polymerase, and ligase components to evaluate relative NHEJ efficiency and analyze ligated junctional sequences for various types of DNA ends, including blunt, 5' overhangs, and 3' overhangs. We find that different dsDNA end structures have differential dependence on these enzymatic components. The dependence of some end joining on only Ku and XRCC4.DNA ligase IV allows us to formulate a physical model that incorporates nuclease and polymerase components as needed. PMID- 27703002 TI - Activation of Wnt Signaling in Cortical Neurons Enhances Glucose Utilization through Glycolysis. AB - The Wnt signaling pathway is critical for a number of functions in the central nervous system, including regulation of the synaptic cleft structure and neuroprotection against injury. Deregulation of Wnt signaling has been associated with several brain pathologies, including Alzheimer's disease. In recent years, it has been suggested that the Wnt pathway might act as a central integrator of metabolic signals from peripheral organs to the brain, which would represent a new role for Wnt signaling in cell metabolism. Energy metabolism is critical for normal neuronal function, which mainly depends on glucose utilization. Brain energy metabolism is important in almost all neurological disorders, to which a decrease in the capacity of the brain to utilize glucose has been linked. However, little is known about the relationship between Wnt signaling and neuronal glucose metabolism in the cellular context. In the present study, we found that acute treatment with the Wnt3a ligand induced a large increase in glucose uptake, without changes in the expression or localization of glucose transporter type 3. In addition, we observed that Wnt3a treatment increased the activation of the metabolic sensor Akt. Moreover, we observed an increase in the activity of hexokinase and in the glycolytic rate, and both processes were dependent on activation of the Akt pathway. Furthermore, we did not observe changes in the activity of glucose-6-phosphate dehydrogenase or in the pentose phosphate pathway. The effect of Wnt3a was independent of both the transcription of Wnt target genes and synaptic effects of Wnt3a. Together, our results suggest that Wnt signaling stimulates glucose utilization in cortical neurons through glycolysis to satisfy the high energy demand of these cells. PMID- 27703003 TI - SUMO Modification Reverses Inhibitory Effects of Smad Nuclear Interacting Protein 1 in TGF-beta Responses. AB - SNIP1 (Smad nuclear interacting protein 1) is a transcription repressor for the TGF-beta and NF-kappaB signaling pathways through disrupting the recruitment of co-activator p300. However, it is unclear how the functions of SNIP1 in the TGF beta signaling pathway are controlled. Our present studies show that SNIP1 is covalently modified by small ubiquitin-like modifier (SUMO) in vitro and in vivo at three lysine sites: Lys5, Lys30, and Lys108, with Lys30 being the major SUMO modification site. SUMOylation of SNIP1 is enhanced by SUMO E3 ligase PIAS proteins and inhibited by SUMO proteases SENP1/2. Furthermore, we find that SUMOylation of SNIP1 attenuates its inhibitory effect in TGF-beta signaling because the SUMO-conjugated form of SNIP1 exhibits impaired ability to disrupt the formation of Smad complex and the interaction between p300 and Smads. Subsequently, SUMOylation of SNIP1 leads to the loss of SNIP1-mediated inhibition on expression of the TGF-beta target genes PAI-1 and MMP2 and eventually enhances TGF-beta-regulated cell migration and invasion. PMID- 27703004 TI - Quantitative Proteomics of the SMAD (Suppressor of Mothers against Decapentaplegic) Transcription Factor Family Identifies Importin 5 as a Bone Morphogenic Protein Receptor SMAD-specific Importin. AB - Gene-specific transcription factors (GSTFs) control gene transcription by DNA binding and specific protein complex recruitment, which regulates promoter accessibility for transcription initiation by RNA polymerase II. Mutations in the GSTFs Suppressor of Mothers Against Decapentaplegic 2 (SMAD2) and SMAD4 are frequently associated with colon and rectal carcinomas. These proteins play an important role in bone morphogenic protein (BMP) and transforming growth factor beta (TGF-beta) signaling pathways controlling cell fate and proliferation. To study the protein interactome of the SMAD protein family we generated a quantitative proteomics pipeline that allows for inducible expression of GFP tagged SMAD proteins followed by affinity purification and quantitative mass spectrometry analysis. Data are available via ProteomeXchange with identifier PXD004529. The nuclear importin IPO5 was identified as a novel interacting protein of SMAD1. Overexpression of IPO5 in various cell lines specifically increases nuclear localization of BMP receptor-activated SMADs (R-SMADs) confirming a functional relationship between IPO5 and BMP but not TGF-beta R SMADs. Finally, we provide evidence that variation in length of the lysine stretch of the nuclear localization sequence is a determinant for importin specificity. PMID- 27703005 TI - The R838S Mutation in Retinal Guanylyl Cyclase 1 (RetGC1) Alters Calcium Sensitivity of cGMP Synthesis in the Retina and Causes Blindness in Transgenic Mice. AB - Substitutions of Arg838 in the dimerization domain of a human retinal membrane guanylyl cyclase 1 (RetGC1) linked to autosomal dominant cone-rod degeneration type 6 (CORD6) change RetGC1 regulation in vitro by Ca2+ In addition, we find that R838S substitution makes RetGC1 less sensitive to inhibition by retinal degeneration-3 protein (RD3). We selectively expressed human R838S RetGC1 in mouse rods and documented the decline in rod vision and rod survival. To verify that changes in rods were specifically caused by the CORD6 mutation, we used for comparison cones, which in the same mice did not express R838S RetGC1 from the transgenic construct. The R838S RetGC1 expression in rod outer segments reduced inhibition of cGMP production in the transgenic mouse retinas at the free calcium concentrations typical for dark-adapted rods. The transgenic mice demonstrated early-onset and rapidly progressed with age decline in visual responses from the targeted rods, in contrast to the longer lasting preservation of function in the non-targeted cones. The decline in rod function in the retina resulted from a progressive degeneration of rods between 1 and 6 months of age, with the severity and pace of the degeneration consistent with the extent to which the Ca2+ sensitivity of the retinal cGMP production was affected. Our study presents a new experimental model for exploring cellular mechanisms of the CORD6-related photoreceptor death. This mouse model provides the first direct biochemical and physiological in vivo evidence for the Arg838 substitutions in RetGC1 being the culprit behind the pathogenesis of the CORD6 congenital blindness. PMID- 27703007 TI - Ozone-derived Oxysterols Affect Liver X Receptor (LXR) Signaling: A POTENTIAL ROLE FOR LIPID-PROTEIN ADDUCTS. AB - When inhaled, ozone (O3) interacts with cholesterols of airway epithelial cell membranes or the lung-lining fluid, generating chemically reactive oxysterols. The mechanism by which O3-derived oxysterols affect molecular function is unknown. Our data show that in vitro exposure of human bronchial epithelial cells to O3 results in the formation of oxysterols, epoxycholesterol-alpha and -beta and secosterol A and B (Seco A and Seco B), in cell lysates and apical washes. Similarly, bronchoalveolar lavage fluid obtained from human volunteers exposed to O3 contained elevated levels of these oxysterol species. As expected, O3-derived oxysterols have a pro-inflammatory effect and increase NF-kappaB activity. Interestingly, expression of the cholesterol efflux pump ATP-binding cassette transporter 1 (ABCA1), which is regulated by activation of the liver X receptor (LXR), was suppressed in epithelial cells exposed to O3 Additionally, exposure of LXR knock-out mice to O3 enhanced pro-inflammatory cytokine production in the lung, suggesting LXR inhibits O3-induced inflammation. Using alkynyl surrogates of O3-derived oxysterols, our data demonstrate adduction of LXR with Seco A. Similarly, supplementation of epithelial cells with alkynyl-tagged cholesterol followed by O3 exposure causes observable lipid-LXR adduct formation. Experiments using Seco A and the LXR agonist T0901317 (T09) showed reduced expression of ABCA1 as compared with stimulation with T0901317 alone, indicating that Seco A LXR protein adduct formation inhibits LXR activation by traditional agonists. Overall, these data demonstrate that O3-derived oxysterols have pro-inflammatory functions and form lipid-protein adducts with LXR, thus leading to suppressed cholesterol regulatory gene expression and providing a biochemical mechanism mediating O3-derived formation of oxidized lipids in the airways and subsequent adverse health effects. PMID- 27703006 TI - Bipartite Role of Heat Shock Protein 90 (Hsp90) Keeps CRAF Kinase Poised for Activation. AB - CRAF kinase maintains cell viability, growth, and proliferation by participating in the MAPK pathway. Unlike BRAF, CRAF requires continuous chaperoning by Hsp90 to retain MAPK signaling. However, the reason behind the continuous association of Hsp90 with CRAF is still elusive. In this study, we have identified the bipartite role of Hsp90 in chaperoning CRAF kinase. Hsp90 facilitates Ser-621 phosphorylation of CRAF and prevents the kinase from degradation. Co-chaperone Cdc37 assists in this phosphorylation event. However, after folding, the stability of the kinase becomes insensitive to Hsp90 inhibition, although the physical association between Hsp90 and CRAF remains intact. We observed that overexpression of Hsp90 stimulates MAPK signaling by activating CRAF. The interaction between Hsp90 and CRAF is substantially increased under an elevated level of cellular Hsp90 and in the presence of either active Ras (RasV12) or EGF. Surprisingly, enhanced binding of Hsp90 to CRAF occurs prior to the Ras-CRAF association and facilitates actin recruitment to CRAF for efficient Ras-CRAF interaction, which is independent of the ATPase activity of Hsp90. However, monomeric CRAF (CRAFR401H) shows abrogated interaction with both Hsp90 and actin, thereby affecting Hsp90-dependent CRAF activation. This finding suggests that stringent assemblage of Hsp90 keeps CRAF kinase equipped for participating in the MAPK pathway. Thus, the role of Hsp90 in CRAF maturation and activation acts as a limiting factor to maintain the function of a strong client like CRAF kinase. PMID- 27703008 TI - The Role of Folate Transport in Antifolate Drug Action in Trypanosoma brucei. AB - The aim of this study was to identify and characterize mechanisms of resistance to antifolate drugs in African trypanosomes. Genome-wide RNAi library screens were undertaken in bloodstream form Trypanosoma brucei exposed to the antifolates methotrexate and raltitrexed. In conjunction with drug susceptibility and folate transport studies, RNAi knockdown was used to validate the functions of the putative folate transporters. The transport kinetics of folate and methotrexate were further characterized in whole cells. RNA interference target sequencing experiments identified a tandem array of genes encoding a folate transporter family, TbFT1-3, as major contributors to antifolate drug uptake. RNAi knockdown of TbFT1-3 substantially reduced folate transport into trypanosomes and reduced the parasite's susceptibly to the classical antifolates methotrexate and raltitrexed. In contrast, knockdown of TbFT1-3 increased susceptibly to the non classical antifolates pyrimethamine and nolatrexed. Both folate and methotrexate transport were inhibited by classical antifolates but not by non-classical antifolates or biopterin. Thus, TbFT1-3 mediates the uptake of folate and classical antifolates in trypanosomes, and TbFT1-3 loss-of-function is a mechanism of antifolate drug resistance. PMID- 27703009 TI - Epithelial Cholesterol Deficiency Attenuates Human Antigen R-linked Pro inflammatory Stimulation via an SREBP2-linked Circuit. AB - Patients with chronic intestinal ulcerative diseases, such as inflammatory bowel disease, tend to exhibit abnormal lipid profiles, which may affect the gut epithelial integrity. We hypothesized that epithelial cholesterol depletion may trigger inflammation-checking machinery via cholesterol sentinel signaling molecules whose disruption in patients may aggravate inflammation and disease progression. In the present study, sterol regulatory element-binding protein 2 (SREBP2) as the cholesterol sentinel was assessed for its involvement in the epithelial inflammatory responses in cholesterol-depleted enterocytes. Patients and experimental animals with intestinal ulcerative injuries showed suppression in epithelial SREBP2. Moreover, SREBP2-deficient enterocytes showed enhanced pro inflammatory signals in response to inflammatory insults, indicating regulatory roles of SREBP2 in gut epithelial inflammation. However, epithelial cholesterol depletion transiently induced pro-inflammatory chemokine expression regardless of the well known pro-inflammatory nuclear factor-kappaB signals. In contrast, cholesterol depletion also exerts regulatory actions to maintain epithelial homeostasis against excessive inflammation via SREBP2-associated signals in a negative feedback loop. Mechanistically, SREBP2 and its induced target EGR-1 were positively involved in induction of peroxisome proliferator-activated receptor gamma (PPARgamma), a representative anti-inflammatory transcription factor. As a crucial target of the SREBP2-EGR-1-PPARgamma-associated signaling pathways, the mRNA stabilizer, human antigen R (HuR) was retained in nuclei, leading to reduced stability of pro-inflammatory chemokine transcripts. This mechanistic investigation provides clinical insights into protective roles of the epithelial cholesterol deficiency against excessive inflammatory responses via the SREBP2 HuR circuit, although the deficiency triggers transient pro-inflammatory signals. PMID- 27703010 TI - Hepatic ZIP14-mediated Zinc Transport Contributes to Endosomal Insulin Receptor Trafficking and Glucose Metabolism. AB - Zinc influences signaling pathways through controlled targeted zinc transport. Zinc transporter Zip14 KO mice display a phenotype that includes impaired intestinal barrier function with low grade chronic inflammation, hyperinsulinemia, and increased body fat, which are signatures of diet-induced diabetes (type 2 diabetes) and obesity in humans. Hyperglycemia in type 2 diabetes and obesity is caused by insulin resistance. Insulin resistance results in inhibition of glucose uptake by liver and other peripheral tissues, principally adipose and muscle and with concurrently higher hepatic glucose production. Therefore, modulation of hepatic glucose metabolism is an important target for antidiabetic treatment approaches. We demonstrate that during glucose uptake, cell surface abundance of zinc transporter ZIP14 and mediated zinc transport increases. Zinc is distributed to multiple sites in hepatocytes through sequential translocation of ZIP14 from plasma membrane to early and late endosomes. Endosomes from Zip14 KO mice were zinc-deficient because activities of the zinc-dependent insulin-degrading proteases insulin-degrading enzyme and cathepsin D were impaired; hence insulin receptor activity increased. Transient increases in cytosolic zinc levels are concurrent with glucose uptake and suppression of glycogen synthesis. In contrast, Zip14 KO mice exhibited greater hepatic glycogen synthesis and impaired gluconeogenesis and glycolysis related to low cytosolic zinc levels. We can conclude that ZIP14-mediated zinc transport contributes to regulation of endosomal insulin receptor activity and glucose homeostasis in hepatocytes. Therefore, modulation of ZIP14 transport activity presents a new target for management of diabetes and other glucose-related disorders. PMID- 27703011 TI - A Role for Ceramides, but Not Sphingomyelins, as Antagonists of Insulin Signaling and Mitochondrial Metabolism in C2C12 Myotubes. AB - The accumulation of sphingolipids in obesity leads to impairments in insulin sensitivity and mitochondrial metabolism, but the precise species driving these defects is unclear. We have modeled these obesity-induced effects in cultured C2C12 myotubes, using BSA-conjugated palmitate to increase synthesis of endogenous sphingolipids and to inhibit insulin signaling and oxidative phosphorylation. Palmitate (a) induced the accumulation of sphingomyelin (SM) precursors such as sphinganine, dihydroceramide, and ceramide; (b) inhibited insulin stimulation of a central modulator of anabolic metabolism, Akt/PKB; (c) inhibited insulin-stimulated glycogen synthesis; and (d) decreased oxygen consumption and ATP synthesis. Under these conditions, palmitate failed to alter levels of SMs, which are the most abundant sphingolipids, suggesting that they are not the primary intermediates accounting for the deleterious palmitate effects. Treating cells with a pharmacological inhibitor of SM synthase or using CRISPR to knock out the Sms2 gene recapitulated the palmitate effects by inducing the accumulation of SM precursors and impairing insulin signaling and mitochondrial metabolism. To profile the sphingolipids that accumulate in obesity, we performed lipidomics on quadriceps muscles from obese mice with impaired glucose tolerance. Like the cultured myotubes, these tissues accumulated ceramides but not SMs. Collectively, these data suggest that SM precursors such as ceramides, rather than SMs, are likely nutritional antagonists of metabolic function in skeletal muscle. PMID- 27703012 TI - Role of Glycosyltransferases Modifying Type B Flagellin of Emerging Hypervirulent Clostridium difficile Lineages and Their Impact on Motility and Biofilm Formation. AB - Clostridium difficile is the principal cause of nosocomial infectious diarrhea worldwide. The pathogen modifies its flagellin with either a type A or type B O linked glycosylation system, which has a contributory role in pathogenesis. We study the functional role of glycosyltransferases modifying type B flagellin in the 023 and 027 hypervirulent C. difficile lineages by mutagenesis of five putative glycosyltransferases and biosynthetic genes. We reveal their roles in the biosynthesis of the flagellin glycan chain and demonstrate that flagellar post-translational modification affects motility and adhesion-related bacterial properties of these strains. We show that the glycosyltransferases 1 and 2 (GT1 and GT2) are responsible for the sequential addition of a GlcNAc and two rhamnoses, respectively, and that GT3 is associated with the incorporation of a novel sulfonated peptidyl-amido sugar moiety whose structure is reported in our accompanying paper (Bouche, L., Panico, M., Hitchen, P., Binet, D., Sastre, F., Faulds-Pain, A., Valiente, E., Vinogradov, E., Aubry, A., Fulton, K., Twine, S., Logan, S.

Whereas type B modification is not required for flagellar assembly, some mutations that result in truncation or abolition of the glycan reduce bacterial motility and promote autoaggregation and biofilm formation. The complete lack of flagellin modification also significantly reduces adhesion of C. difficile to Caco-2 intestinal epithelial cells but does not affect activation of human TLR5. Our study advances our understanding of the genes involved in flagellar glycosylation and their biological roles in emerging hypervirulent C. difficile strains.

AB - Pyoverdines are high affinity siderophores produced by a broad range of pseudomonads to enhance growth under iron deficiency. They are especially relevant for pathogenic and mutualistic strains that inhabit iron-limited environments. Pyoverdines are generated from non-ribosomally synthesized highly modified peptides. They all contain an aromatic chromophore that is formed in the periplasm by intramolecular cyclization steps. Although the cytoplasmic peptide synthesis and side-chain modifications are well characterized, the periplasmic maturation steps are far from understood. Out of five periplasmic enzymes, PvdM, PvdN, PvdO, PvdP, and PvdQ, functions have been attributed only to PvdP and PvdQ. The other three enzymes are also regarded as essential for siderophore biosynthesis. The structure of PvdN has been solved recently, but no function could be assigned. Here we present the first in-frame deletion of the PvdN encoding gene. Unexpectedly, PvdN turned out to be required for a specific modification of pyoverdine, whereas the overall amount of fluorescent pyoverdines was not altered by the mutation. The mutant strain grew normally under iron limiting conditions. Mass spectrometry identified the PvdN-dependent modification as a transformation of the N-terminal glutamic acid to a succinamide. We postulate a pathway for this transformation catalyzed by the enzyme PvdN, which is most likely functional in the case of all pyoverdines.

AB - In the mammalian endoplasmic reticulum, oxidoreductin-1alpha (Ero1alpha) generates protein disulfide bonds and transfers them specifically to canonical protein-disulfide isomerase (PDI) to sustain oxidative protein folding. This oxidative process is coupled to the reduction of O2 to H2O2 on the bound flavin adenine dinucleotide cofactor. Because excessive thiol oxidation and H2O2 generation cause cell death, Ero1alpha activity must be properly regulated. In addition to the four catalytic cysteines (Cys94, Cys99, Cys104, and Cys131) that are located in the flexible active site region, the Cys208-Cys241 pair located at the base of another flexible loop is necessary for Ero1alpha regulation, although the mechanistic basis is not fully understood. The present study revealed that the Cys208-Cys241 disulfide was reduced by PDI and other PDI family members during PDI oxidation. Differential scanning calorimetry and small angle X-ray scattering showed that mutation of Cys208 and Cys241 did not grossly affect the thermal stability or overall shape of Ero1alpha, suggesting that redox regulation of this cysteine pair serves a functional role. Moreover, the flexible loop flanked by Cys208 and Cys241 provides a platform for functional interaction with PDI, which in turn enhances the oxidative activity of Ero1alpha through reduction of the Cys208-Cys241 disulfide. We propose a mechanism of dual Ero1alpha regulation by dynamic redox interactions between PDI and the two Ero1alpha flexible loops that harbor the regulatory cysteines.

AB - Human NSun6 is an RNA methyltransferase that catalyzes the transfer of the methyl group from S-adenosyl-l-methionine (SAM) to C72 of tRNAThr and tRNACys In the current study, we used mass spectrometry to demonstrate that human NSun6 indeed introduces 5-methylcytosine (m5C) into tRNA, as expected. To further reveal the tRNA recognition mechanism of human NSun6, we measured the methylation activity of human NSun6 and its kinetic parameters for different tRNA substrates and their mutants. We showed that human NSun6 requires a well folded, full-length tRNA as its substrate. In the acceptor region, the CCA terminus, the target site C72, the discriminator base U73, and the second and third base pairs (2:71 and 3:70) of the acceptor stem are all important RNA recognition elements for human NSun6. In addition, two specific base pairs (11:24 and 12:23) in the D-stem of the tRNA substrate are involved in interacting with human NSun6. Together, our findings suggest that human NSun6 relies on a delicate network for RNA recognition, which involves both the primary sequence and tertiary structure of tRNA substrates.

GPM is caused by a fungal invasion into the mucosal lining of the guttural pouches and, frequently, the associated neurovascular structures. Although several species of fungi have been associated with this disease, Aspergillus spp. appear to be the most common isolated from the guttural pouches. However, it remains unclear which are the predisposing factors leading to the development of the infection. The objectives of the present study were to experimentally reproduce an infection by Aspergillus fumigatus and to follow the natural evolution of the mycosis. Eight guttural pouches from four horses were experimentally infected by endoscopy-guided intrapouch inoculation of A. fumigatus culture. Horses were monitored for clinical signs and development of fungal plaques through endoscopic examination. Mycotic lesions were observed in all the horses and a spontaneous regression was observed within 15-28 days. No development of clinical signs was noticed. In conclusion, we were able to induce the development of mycotic lesions and to observe a natural regression of these lesions without clinical signs. PMID- 27703016 TI - Posaconazole plasma concentrations in pediatric patients receiving antifungal prophylaxis during neutropenia. AB - Invasive fungal infections are one of the major complications in pediatric patients during prolonged neutropenia after chemotherapy. Evaluation of the efficacy and safety of the triazole posaconazole in these patients is missing. This multicenter survey analyzed trough concentrations of 33 pediatric patients with a median age of 8 years during 108 neutropenic episodes who received prophylactic posaconazole oral suspension. A total of 172 posaconazole trough levels were determined to median 438 ng/ml (range 111-2011 ng/ml; mean 468 +/- 244 ng/ml). Age and gender had no influence on posaconazole plasma levels. Posaconazole was not discontinued due to adverse events in any of the patients. Only hepatic parameters significantly increased beyond the upper normal limit to median values of ALT of 87 U/l (P < .0001), and AST of 67 U/l (P < .0001). One patient with a median posaconazole trough concentration of 306 ng/ml experienced an invasive fungal infection. In conclusion, posaconazole was effective, safe and feasible in 33 pediatric patients with neutropenia >=5 days after chemotherapy. Median posaconazole plasma concentrations were approximately 1.6-fold lower than the recommended plasma level of 700 ng/ml. Larger patient cohorts are needed to evaluate these findings. PMID- 27703019 TI - Chemical and physical strategies in onychomycosis topical treatment: A review. AB - Onychomycosis is a fungal infection of the fingernails or toenails caused by dermatophytes, nondermatophytes, moulds, and yeasts. This condition affects around 10-30% people worldwide, negatively influencing patients' quality of life, with severe outcomes in some cases. Since the nail unit acts as a barrier to exogenous substances, its physiological features hampers drug penetration, turning the onychomycosis treatment a challenge. Currently, there are several oral and topical therapies available; nevertheless, cure rates are still low and relapse rates achieves 10-53%. Also, serious side effects may be developed due to long-term treatment. In light of these facts, researchers have focused on improving topical treatments, either by modifying the vehicle or by using some physical technique to improve drug delivery trough the nail plate, hence increasing therapy effectiveness. Therefore, the aim of this paper is to explain these novel alternative approaches. First, the challenges for drug ungual penetration are presented. Then, the chemical and physical strategies developed for overcoming the barriers for drug penetration are discussed. We hope that the information gathered may be useful for the development of safer and more effective treatments for onychomycosis. PMID- 27703017 TI - Hospitalized burden and outcomes of coccidioidomycosis: A nationwide analysis, 2005-2012. AB - The incidence of coccidioidomycosis (CM) infection has increased over the last 20 years. We investigated recent trends of CM-associated hospitalization in the United States. patients with CM-associated hospitalization were identified from the Nationwide Inpatient Sample, 2005-2012. The outcomes of interest were the trend of annual hospitalization, in-hospital mortality, and independent risk factors for mortality. A total of 30,870 hospitalizations with CM (29,584 of adults; 1,286 of children) were identified. Over the 8-year study period, the number of hospitalizations for CM fluctuated but increased overall with successively higher peaks in 2009 and 2011. The annual median length of stay (LOS) shortened from 6 to 7 days in 2005-2010 to 4 days in 2011 and 5 days in 2012. The inflation-adjusted hospital charges were highest in 2006 then trended down by 21% in 2012. The in-hospital mortality declined from the highest level in 2005 (5.2%) to a low in 2010 (1.1%), then increased modestly in 2011 (1.9%) and 2012 (1.5%). Hospitalizations were identified in 46 states, with nearly half in Arizona (49.1%), followed by California (36.8%), Texas (3.3%), and Nevada (1.6%). Logistic regression analysis in adults revealed that in-hospital mortality was associated with age groups 61-70 years and >70 years (OR = 3.3 and 3.5, respectively. Ref: 18-30 years) and Charlson Index >=1 (OR = 2.0-8.3). In children, males had lower risk for mortality than females (OR = 0.2). This study shows that CM-associated hospitalizations occur widely throughout the United States with an increasing admission trend; however, patient outcomes have improved and the cost of hospitalization has decreased. PMID- 27703020 TI - Gut yeast communities in Larus michahellis from various breeding colonies. AB - Yellow-legged gulls have been reported to carry antibiotic-resistant Enterobacteriaceae; however, the gut mycobiota of these birds has not yet been described. In this study, we analyzed the gut yeast communities in five yellow legged gull breeding colonies along the Mediterranean littoral in southern France. Gull fecal samples were inoculated onto four types of culture media, including one supplemented with itraconazole. Yeast species richness, abundance, and diversity were estimated, and factorial analysis was used to highlight correspondences between breeding colonies. Yeast grew in 113 of 177 cultures, and 17 distinct yeast species were identified. The most frequent species were Candida krusei (53.5%), Galactomyces geotrichum (44.1%), C. glabrata (40.9%), C. albicans (20.5%), and Saccharomyces cerevisiae (18.1%). Gut yeast community structure in the gulls at both Pierre-Blanche Lagoon (PB) and Frioul Archipelago (F) were characterized by greater species richness and diversity than in those at the two cities of La Grande-Motte (GM) and Palavas-les-Flots (PF) as well as Riou Archipelago (R). Gulls in these latter three sites probably share a similar type of anthropogenic diet. Notably, the proportion of anthropic yeast species, including C. albicans and C. glabrata, in the gull mycobiota increased with gull colony synanthropy. Antifungal resistance was found in each of the five most frequent yeast species. We found that the gut yeast communities of these yellow legged gulls include antifungal-resistant human pathogens. Further studies should assess the public health impact of these common synanthropic seabirds, which represent a reservoir and disseminator of drug-resistant human pathogenic yeast into the environment. PMID- 27703021 TI - Aspergillus antibody detection: diagnostic strategy and technical considerations from the Societe Francaise de Mycologie Medicale (French Society for Medical Mycology) expert committee. AB - Until now, there has been no consensus on the best method for the detection of anti-Aspergillus antibodies, a key diagnostic tool for chronic aspergilloses. To better appreciate the usage of and confidence in these techniques, the Societe Francaise de Mycologie Medicale (French Society for Medical Mycology; SFMM) performed a two-step survey of French experts. First, we administered an initial survey to French labs performing Aspergillus serology to depict usage of the different techniques available for Aspergillus serology. Second, an opinion poll was conducted of 40 experts via an online questionnaire. Each item was rated from 1 to 9 according to the level of agreement. The initial survey revealed that enzyme-linked immunosorbent assay (ELISA) (81%) and immunoelectrophoresis (IEP) (67%) were the most commonly used techniques for screening and confirmation, respectively. The distinction between screening and confirmation techniques was confirmed by the experts (median = 7) with a 44.2% variation coefficient. Only ELISA for screening and IEP and Western blot (WB) for confirmation were clearly considered valuable methods (median >=8 with variation coefficients less than 30%). The use of a confirmation technique was recommended in the case of a positive result in a compatible clinical context (cystic fibrosis, for example) or during the patient's follow-up. In the case of discordant results between the screening and confirmation techniques, the experts recommended greater confidence in the results obtained with the confirmation technique. All experts emphasized the need to standardize Aspergillus serology techniques and to better define the place of each of them in the diagnosis of aspergillosis. PMID- 27703022 TI - Epidemiological features of invasive mold infections among solid organ transplant recipients: PATH Alliance(r) registry analysis. AB - Epidemiological characteristics of 333 proven and probable invasive mould infections (IMIs) among solid organ transplant recipients (SOTRs) identified between 2004 and 2008 from the Prospective Antifungal Therapy Alliance (PATH) registry are presented. Liver transplant recipients (LTRs) had the lowest median time to IMIs (109 days; interquartile range [IQR] 24-611 days), the highest rate of disseminated disease (n/N = 18/33; 55%), and highest mortality (n/N = 21/33; 64%). Lung transplant recipients had highest median time to IMIs (486 days; IQR 117-1358 days) and lowest mortality (n/N = 31/184; 17%). Complete or partial response at week 12 in patients with invasive aspergillosis (IA) was 67% (n/N = 189/281), and 41% (n/N = 9/22) in mucormycosis patients. In the composite outcome of death or no response to therapy, LTRs had the worst outcome. Higher suspicion of mold infection and institution of appropriate antifungal prophylactic strategies are warranted, especially in high risk LTRs. PMID- 27703023 TI - Dosing and therapeutic drug monitoring of voriconazole in bottlenose dolphins (Tursiops truncatus). AB - Bottlenose dolphins (Tursiops truncatus) can suffer from fungal infections, which can be treated with voriconazole. In common practice, the voriconazole doses are extrapolated from human doses by adjusting for body weight only, because no dose regimen is available yet. Therefore, the aim of this study was to define a dose regimen for voriconazole in bottlenose dolphins. Dolphins treated with voriconazole between November 2005 and September 2015 at the Dolfinarium Harderwijk, the Netherlands, and TDM was performed were included. Voriconazole plasma concentrations were analyzed with a HPLC-UV method. A population pharmacokinetic model was developed using Mw/Pharm in which the elimination rate constant (ke) and apparent total distribution volume (Vd) was calculated. The loading dose was calculated using the central Vd (Vdc). The maintenance dose was simulated in Mw/Pharm using ke and total Vd.Eleven dolphins were included. Ke was estimated to be 0.0026 +/- 0.0007 hour-1 (mean +/- SD), Vd 5.3 +/- 3.2 l/kg (mean +/- SD), and Vdc ranged between 1.8 and 2.8 l/kg (mean 2.2 l/kg). In order to obtain a median top plasma concentration of 5 mg/l, the loading dose was calculated to be 10 mg/kg (range 9.0-14.2 mg/kg) divided in three administrations (3.3 mg/kg every 24 hours). The maintenance dose was calculated to be 4 mg/kg once a week (range 1.7-6.0 mg/kg); 17% of the dolphins did not reach the therapeutic window of 1-5 mg/l without TDM. A TDM-guided dosing algorithm was developed in order to obtain therapeutic plasma concentrations in this population. PMID- 27703024 TI - Plasma Triglycerides and HDL-C Levels Predict the Development of Diabetic Kidney Disease in Subjects With Type 2 Diabetes: The AMD Annals Initiative. AB - OBJECTIVE: Despite the achievement of blood glucose, blood pressure, and LDL cholesterol (LDL-C) targets, the risk for diabetic kidney disease (DKD) remains high among patients with type 2 diabetes. This observational retrospective study investigated whether diabetic dyslipidemia-that is, high triglyceride (TG) and/or low HDL cholesterol (HDL-C) levels-contributes to this high residual risk for DKD. RESEARCH DESIGN AND METHODS: Among a total of 47,177 patients attending Italian diabetes centers, 15,362 patients with a baseline estimated glomerular filtration rate (eGFR) >=60 mL/min/1.73 m2, normoalbuminuria, and LDL-C <=130 mg/dL completing a 4-year follow-up were analyzed. The primary outcome was the incidence of DKD, defined as either low eGFR (<60 mL/min/1.73 m2) or an eGFR reduction >30% and/or albuminuria. RESULTS: Overall, 12.8% developed low eGFR, 7.6% an eGFR reduction >30%, 23.2% albuminuria, and 4% albuminuria and either eGFR <60 mL/min/1.73 m2 or an eGFR reduction >30%. TG >=150 mg/dL increased the risk of low eGFR by 26%, of an eGFR reduction >30% by 29%, of albuminuria by 19%, and of developing one abnormality by 35%. HDL-C <40 mg/dL in men and <50 mg/dL in women were associated with a 27% higher risk of low eGFR and a 28% risk of an eGFR reduction >30%, with a 24% higher risk of developing albuminuria and a 44% risk of developing one abnormality. These associations remained significant when TG and HDL-C concentrations were examined as continuous variables and were only attenuated by multivariate adjustment for numerous confounders. CONCLUSIONS: In a large population of outpatients with diabetes, low HDL-C and high TG levels were independent risk factors for the development of DKD over 4 years. PMID- 27703025 TI - An Unbiased Lipidomics Approach Identifies Early Second Trimester Lipids Predictive of Maternal Glycemic Traits and Gestational Diabetes Mellitus. AB - OBJECTIVE: To investigate the relationship between early second trimester serum lipidomic variation and maternal glycemic traits at 28 weeks and to identify predictive lipid biomarkers for gestational diabetes mellitus (GDM). RESEARCH DESIGN AND METHODS: Prospective study of 817 pregnant women (discovery cohort, n = 200; validation cohort, n = 617) who provided an early second trimester serum sample and underwent an oral glucose tolerance test (OGTT) at 28 weeks. In the discovery cohort, lipids were measured using direct infusion mass spectrometry and correlated with OGTT results. Variable importance in projection (VIP) scores were used to identify candidate lipid biomarkers. Candidate biomarkers were measured in the validation cohort using liquid chromatography-mass spectrometry and tested for associations with OGTT results and GDM status. RESULTS: Early second trimester lipidomic variation was associated with 1-h postload glucose levels but not with fasting plasma glucose levels. Of the 13 lipid species identified by VIP scores, 10 had nominally significant associations with postload glucose levels. In the validation cohort, 5 of these 10 lipids had significant associations with postload glucose levels that were independent of maternal age and BMI, i.e., TG(51.1), TG(48:1), PC(32:1), PCae(40:3), and PCae(40:4). All except the last were also associated with maternal GDM status. Together, these four lipid biomarkers had moderate ability to predict GDM (area under curve [AUC] = 0.71 +/- 0.04, P = 4.85 * 10-7) and improved the prediction of GDM by age and BMI alone from AUC 0.69 to AUC 0.74. CONCLUSIONS: Specific early second trimester lipid biomarkers can predict maternal GDM status independent of maternal age and BMI, potentially enhancing risk factor-based screening.

PMID- 27703026 TI - Exposure to Gestational Diabetes Mellitus: Impact on the Development of Early Onset Type 2 Diabetes in Canadian First Nations and Non-First Nations Offspring. AB - OBJECTIVE: Type 2 diabetes is increasing in children worldwide, with Canadian First Nations (FN) children disproportionally affected. The prevalence of gestational diabetes mellitus (GDM) also is increasing. The objective of this study was to evaluate the impact of GDM exposure in utero and FN status on the subsequent risk of type 2 diabetes in offspring in the first 30 years of life. RESEARCH DESIGN AND METHODS: In this population-based historical prospective cohort study, we used administrative databases linked to a clinical database to explore the independent association and interaction between GDM and FN status on the subsequent development of type 2 diabetes in offspring. RESULTS: Among 321,008 births with a median follow-up of 15.1 years, both maternal GDM and FN status were independently associated with subsequent risk of type 2 diabetes in offspring in the first 30 years of life (hazard ratio 3.03 [95% CI 2.44-3.76; P < 0.0001] vs. 4.86 [95% CI 4.08-5.79; P < 0.0001], respectively). No interaction between GDM and FN status on type 2 diabetes risk was observed. FN status had a stronger impact on the development of type 2 diabetes in offspring than GDM. CONCLUSIONS: GDM is an important modifiable risk factor for type 2 diabetes, and its prevention may reduce the prevalence of subsequent type 2 diabetes in offspring. This study adds unique and rigorous evidence to the global public health debate about the impact of GDM on the long-term health of offspring.

AB - Patients with a mesenchymal subtype of ovarian cancer face a poor prognosis with limited treatment options to halt metastatic progression. In this issue of Science Signaling, Antony et al found that the kinase AXL drives the mesenchymal gene signature and motility of ovarian tumor cells. AXL inhibitors may thus slow tumor progression in this subset of patients. PMID- 27703028 TI - APOE Genotypes Associate With Cognitive Performance but Not Cerebral Structure: Diabetes Heart Study MIND. AB - OBJECTIVE: Dementia is a debilitating illness with a disproportionate burden in patients with type 2 diabetes (T2D). Among the contributors, genetic variation at the apolipoprotein E locus (APOE) is posited to convey a strong effect. This study compared and contrasted the association of APOE with cognitive performance and cerebral structure in the setting of T2D. RESEARCH DESIGN AND METHODS: European Americans from the Diabetes Heart Study (DHS) MIND (n = 754) and African Americans from the African American (AA)-DHS MIND (n = 517) were examined. The cognitive battery assessed executive function, memory, and global cognition, and brain MRI was performed. RESULTS: In European Americans and African Americans, the APOE E4 risk haplotype group was associated with poorer performance on the modified Mini-Mental Status Examination (P < 0.017), a measure of global cognition. In contrast to the literature, the APOE E2 haplotype group, which was overrepresented in these participants with T2D, was associated with poorer Rey Auditory Verbal Learning Test performance (P < 0.032). Nominal associations between APOE haplotype groups and MRI-determined cerebral structure were observed. CONCLUSIONS: Compared with APOE E3 carriers, E2 and E4 carriers performed worse in the cognitive domains of memory and global cognition. Identification of genetic contributors remains critical to understanding new pathways to prevent and treat dementia in the setting of T2D. PMID- 27703031 TI - Quantitative phosphoproteomic analysis identifies the critical role of JNK1 in neuroinflammation induced by Japanese encephalitis virus. AB - Japanese encephalitis virus (JEV) is the leading cause of epidemic encephalitis worldwide. The pathogenesis of JEV is linked to a robust inflammatory response in the central nervous system (CNS). Glial cells are the resident immune cells in the CNS and represent critical effectors of CNS inflammation. To obtain a global overview of signaling events in glial cells during JEV infection, we conducted phosphoproteomics profiling of a JEV-infected glial cell line. We identified 1816 phosphopeptides, corresponding to 1264 proteins, that exhibited a change in phosphorylation status upon JEV infection. Bioinformatics analysis revealed that these proteins were predominantly related to transcription regulation, signal transduction, the cell cycle, and the cytoskeleton. Kinase substrate motif revealed that substrates for c-Jun N-terminal kinase 1 (JNK1) were the most overrepresented, along with evidence of increased AKT1 and protein kinase A (PKA) signaling. Pharmacological inhibition of JNK, AKT, or PKA reduced the inflammatory response of cultured glial cells infected with JEV, as did knockdown of JNK1 or its target JUN. JEV genomic RNA was sufficient to activate JNK1 signaling in cultured glial cells. Of potential clinical relevance, we showed that inhibition of JNK signaling significantly attenuated the production of inflammatory cytokines in the brain and reduced lethality in JEV-infected mice, thereby suggesting that JNK signaling is a potential therapeutic target for the management of Japanese encephalitis. PMID- 27703030 TI - The GAS6-AXL signaling network is a mesenchymal (Mes) molecular subtype-specific therapeutic target for ovarian cancer. AB - Ovarian cancer is a complex disease with heterogeneity among the gene expression molecular subtypes (GEMS) between patients. Patients with tumors of a mesenchymal ("Mes") subtype have a poorer prognosis than patients with tumors of an epithelial ("Epi") subtype. We evaluated GEMS of ovarian cancer patients for molecular signaling profiles and assessed how the differences in these profiles could be leveraged to improve patient clinical outcome. Kinome enrichment analysis identified AXL as a particularly abundant kinase in Mes-subtype tumor tissue and cell lines. In Mes cells, upon activation by its ligand GAS6, AXL coclustered with and transactivated the receptor tyrosine kinases (RTKs) cMET, EGFR, and HER2, producing sustained extracellular signal-regulated kinase (ERK) activation. In Epi-A cells, AXL was less abundant and induced a transient activation of ERK without evidence of RTK transactivation. AXL-RTK crosstalk also stimulated sustained activation of the transcription factor FRA1, which correlated with the induction of the epithelial-mesenchymal transition (EMT) associated transcription factor SLUG and stimulation of motility exclusively in Mes-subtype cells. The AXL inhibitor R428 attenuated RTK and ERK activation and reduced cell motility in Mes cells in culture and reduced tumor growth in a chick chorioallantoic membrane model. A higher concentration of R428 was needed to inhibit ERK activation and cell motility in Epi-A cells. Silencing AXL in Mes subtype cells reversed the mesenchymal phenotype in culture and abolished tumor formation in an orthotopic xenograft mouse model. Thus, AXL-targeted therapy may improve clinical outcome for patients with Mes-subtype ovarian cancer. PMID- 27703032 TI - Superresolution imaging of the cytoplasmic phosphatase PTPN22 links integrin mediated T cell adhesion with autoimmunity. AB - Integrins are heterodimeric transmembrane proteins that play a fundamental role in the migration of leukocytes to sites of infection or injury. We found that protein tyrosine phosphatase nonreceptor type 22 (PTPN22) inhibits signaling by the integrin lymphocyte function-associated antigen-1 (LFA-1) in effector T cells. PTPN22 colocalized with its substrates at the leading edge of cells migrating on surfaces coated with the LFA-1 ligand intercellular adhesion molecule-1 (ICAM-1). Knockout or knockdown of PTPN22 or expression of the autoimmune disease-associated PTPN22-R620W variant resulted in the enhanced phosphorylation of signaling molecules downstream of integrins. Superresolution imaging revealed that PTPN22-R620 (wild-type PTPN22) was present as large clusters in unstimulated T cells and that these disaggregated upon stimulation of LFA-1, enabling increased association of PTPN22 with its binding partners at the leading edge. The failure of PTPN22-R620W molecules to be retained at the leading edge led to increased LFA-1 clustering and integrin-mediated cell adhesion. Our data define a previously uncharacterized mechanism for fine-tuning integrin signaling in T cells, as well as a paradigm of autoimmunity in humans in which disease susceptibility is underpinned by inherited phosphatase mutations that perturb integrin function. PMID- 27703033 TI - Video-Only Cardiopulmonary Resuscitation Education for High-Risk Families Before Hospital Discharge: A Multicenter Pragmatic Trial. AB - BACKGROUND: Cardiopulmonary resuscitation (CPR) training rates in the United States are low, highlighting the need to develop CPR educational approaches that are simpler, with broader dissemination potential. The minimum training required to ensure long-term skill retention remains poorly characterized. We compared CPR skill retention among laypersons randomized to training with video-only (VO; no manikin) with those trained with a video self-instruction kit (VSI; with manikin). We hypothesized that VO training would be noninferior to the VSI approach with respect to chest compression (CC) rate. METHODS AND RESULTS: We performed a prospective, cluster randomized trial of CPR education for family members of patients with high-risk cardiac conditions on hospital cardiac units, using a multicenter pragmatic design. Eight hospitals were randomized to offer either VO or VSI training before discharge using volunteer trainers. CPR skills were assessed 6 months post training. Mean CC rate among those trained with VO compared with those trained with VSI was assessed with a noninferiority margin set at 8 CC per min; as a secondary outcome, mean differences in CC depth were assessed. From February 2012 to May 2015, 1464 subjects were enrolled and 522 subjects completed a skills assessment. The mean CC rates were 87.7 (VO) CC per min and 89.3 (VSI) CC per min; we concluded noninferiority for VO based on a mean difference of -1.6 (90% confidence interval, -5.2 to 2.1). The mean CC depth was 40.2 mm (VO) and 45.8 mm (VSI) with a mean difference of -5.6 (95% confidence interval, -7.6 to -3.7). Results were similar after multivariate regression adjustment. CONCLUSIONS: In this large, prospective trial of CPR skill retention, VO training yielded a noninferior difference in CC rate compared with VSI training. CC depth was greater in the VSI group. These findings suggest a potential trade-off in efforts for broad dissemination of basic CPR skills; VO training might allow for greater scalability and dissemination, but with a potential reduction in CC depth.

PMID- 27703034 TI - Clinical Impact of Subsequent Depression in Patients With a New Diagnosis of Stable Angina: A Population-Based Study. AB - BACKGROUND: Depression is prevalent among patients with myocardial infarction and is associated with a worse prognosis. However, little is known about its importance in patients with chronic stable angina. We conducted a retrospective population-based cohort study to determine the occurrence and predictors of developing depression in patients with a new diagnosis of chronic stable angina. In addition, we sought to understand its impact on subsequent clinical outcomes. METHODS AND RESULTS: Our cohort included patients in Ontario, Canada, with stable angina based on obstructive coronary artery disease found on angiogram. Depression was ascertained by physician billing codes and hospital admissions diagnostic codes. We first developed multivariable Cox proportional hazards models to determine predictors of developing depression. Clinical outcomes of interest included all-cause mortality, admission for myocardial infarction, and subsequent revascularization. Using hierarchical multivariable Cox proportional hazards models with occurrence of depression as a time-varying variable to control for potential immortal time bias, we evaluated the impact of depression on clinical outcomes. Our cohort consisted of 22 917 patients. The occurrence of depression after diagnosis of stable chronic angina was 18.8% over a mean follow up of 1084 days. Predictors of depression included remote history of depression, female sex, and more symptomatic angina based on Canadian Cardiovascular Society class. Patients who developed depression had a higher risk of death (hazard ratio 1.83, 95% confidence interval 1.62-2.07) and admission for myocardial infarction (hazard ratio 1.36, 95% confidence interval 1.10-1.67) compared with nondepressed patients. CONCLUSIONS: Depression is common in patients with chronic stable angina and is associated with increased morbidity and mortality.

PMID- 27703035 TI - CD4+ T Cells Coexpressing CD134 (OX40) Harbor Significantly Increased Levels of Human Herpesvirus 6B DNA Following Umbilical Cord Blood Transplantation. AB - Human herpesvirus 6B (HHV-6B) commonly reactivates after umbilical cord blood transplantation (UCBT) and is associated with delayed engraftment, fever, rash, and central nervous system dysfunction. Recently, CD134 (OX40) has been implicated as a potential viral entry receptor. We evaluated CD4+CD134+/neg-lo and CD8+CD134+/neg-lo cells at day 28 after UCBT in 20 subjects with previously documented HHV-6 reactivation and persistent viremia. Analysis of CD4+CD134+ cells as compared to CD4+CD134neg-lo cells showed 0.308 versus 0.129 copies of HHV-6B/cell (P = .0002). CD8+CD134+/neg-lo cells contained little to no HHV-6B copies. Following UCBT, CD4+CD134+ cells harbor significantly increased levels of HHV-6B, suggesting that CD134 (OX40) may facilitate viral entry.

AB - Coxiella burnetii is a gram-negative bacterium that causes acute and chronic Q fever. Because of the severe adverse effect of whole-cell vaccination, identification of immunodominant antigens of C. burnetii has become a major focus of Q fever vaccine development. We hypothesized that secreted C. burnetii type IV secretion system (T4SS) effectors may represent a major class of CD8+ T-cell antigens, owing to their cytosolic localization. Twenty-nine peptides were identified that elicited robust CD8+ T-cell interferon gamma (IFN-gamma) recall responses from mice infected with C. burnetii. Interestingly, 22 of 29 epitopes were derived from 17 T4SS-related proteins, none of which were identified as immunodominant antigens by using previous antibody-guided approaches. These epitopes were expressed in an attenuated Listeria monocytogenes vaccine strain. Immunization with recombinant L. monocytogenes vaccines induced a robust CD8+ T cell response and conferred measurable protection against C. burnetii infection in mice. These data suggested that T4SS effectors represent an important class of C. burnetii antigens that can induce CD8+ T-cell responses. We also showed that attenuated L. monocytogenes vaccine vectors are an efficient antigen-delivery platform that can be used to induce robust protective CD8+ T-cell immune responses against C. burnetii infection. PMID- 27703038 TI - Induction of an Immune-Protective T-Cell Repertoire With Diverse Genetic Coverage by a Novel Viral-Vectored Tuberculosis Vaccine in Humans. AB - BACKGROUND: Whether a candidate tuberculosis vaccine induces clinically relevant protective T-cell repertoires in humans will not be known until the completion of costly efficacy clinical trials. METHODS: We have developed an integrated immunologic approach to investigate the clinical relevance of T cells induced by a novel tuberculosis vaccine in a phase 1 trial. This approach consists of screening for likely dominant T-cell epitopes, establishing antigen-specific memory T-cell lines for identifying CD8+ and CD4+ T-cell epitopes, determining the ability of vaccine-induced T cells to inhibit mycobacterial growth in infected cells, and examining the genetic diversity of HLA recognition and the clinical relevance of identified T-cell epitopes. RESULTS: A single-dose immunization in BCG-primed adults with an adenovirus-based tuberculosis vaccine elicits a repertoire of memory T cells capable of recognizing multiple Ag85A epitopes. These T cells are polyfunctional and cytotoxic and can inhibit mycobacterial growth in infected target cells. Some identified T-cell epitopes are promiscuous and recognizable by the common HLA alleles. These epitopes are clinically relevant to the epitopes identified in people with latent Mycobacterium tuberculosis infection and treated patients with tuberculosis. CONCLUSIONS: These data support further clinical development of this candidate vaccine. Our approach helps fill the gap in clinical tuberculosis vaccine development.

AB - Increases in inflammation, coagulation, and CD8+ T-cell numbers are associated with an elevated cardiovascular disease (CVD) risk in human immunodeficiency virus (HIV)-infected antiretroviral therapy (ART) recipients. Circulating memory CD8+ T cells that express the vascular endothelium-homing receptor CX3CR1 (fractalkine receptor) are enriched in HIV-infected ART recipients. Thrombin activated receptor (PAR-1) expression is increased in HIV-infected ART recipients and is particularly elevated on CX3CR1+ CD8+ T cells, suggesting that these cells could interact with coagulation elements. Indeed, thrombin directly enhanced T cell receptor-mediated interferon gamma production by purified CD8+ T cells but was attenuated by thrombin-induced release of transforming growth factor beta by platelets. We have therefore identified a population of circulating memory CD8+ T cells in HIV infection that may home to endothelium, can be activated by clot forming elements, and are susceptible to platelet-mediated regulation. Complex interactions between inflammatory elements and coagulation at endothelial surfaces may play an important role in CVD risk in HIV-infected ART recipients.

AB - Duck hepatitis A virus (DHAV) (Picornaviridae) causes an infectious disease in ducks which results in severe losses in duck industry. However, the proper antiviral supportive drugs for this disease have not been discovered. Polysaccharide is the main ingredient of Astragalus that has been demonstrated to directly and indirectly inhibit RNA of viruses replication. In this study, the antiviral activities of Astragalus polysaccharide (APS) and its derivatives against DHAV were evaluated and compared. APS was modified via the sodium trimetaphosphate and sodium tripolyphosphate (STMP-STPP) method and chlorosulfonic acid-pyridine method to obtain its phosphate (pAPS) and sulfate (sAPS), respectively. The infrared structures of APS, pAPS, and sAPS were analyzed with the potassium bromide disc method. Additionally, the antiviral activities were evaluated with the MTT ((4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2 H-tetrazolium bromide) method in vitro and the artificial inoculation method in vivo. The clinical therapy effects were evaluated by mortality rate, liver function-related biochemical indicators, and visual changes in pathological anatomy. The anti-DHAV proliferation effects of APS, pAPS, and sAPS on the viral multiplication process in cell and blood were observed with the reverse transcription-polymerase chain reaction method. The results revealed that pAPS inhibited DHAV proliferation more efficiently in the entire process of viral multiplication than APS and sAPS. Moreover, only pAPS significantly improved the survival rate to 33.5% and reduced the DHAV particle titer in the blood as well as liver lesions in clinical trials. The results indicated that pAPS exhibited greater anti-DHAV activity than APS and sAPS both in vitro and in vivo. PMID- 27703040 TI - The Salivary Protein Repertoire of the Polyphagous Spider Mite Tetranychus urticae: A Quest for Effectors. AB - The two-spotted spider mite Tetranychus urticae is an extremely polyphagous crop pest. Alongside an unparalleled detoxification potential for plant secondary metabolites, it has recently been shown that spider mites can attenuate or even suppress plant defenses. Salivary constituents, notably effectors, have been proposed to play an important role in manipulating plant defenses and might determine the outcome of plant-mite interactions. Here, the proteomic composition of saliva from T. urticae lines adapted to various host plants-bean, maize, soy, and tomato-was analyzed using a custom-developed feeding assay coupled with nano LC tandem mass spectrometry. About 90 putative T. urticae salivary proteins were identified. Many are of unknown function, and in numerous cases belonging to multimembered gene families. RNAseq expression analysis revealed that many genes coding for these salivary proteins were highly expressed in the proterosoma, the mite body region that includes the salivary glands. A subset of genes encoding putative salivary proteins was selected for whole-mount in situ hybridization, and were found to be expressed in the anterior and dorsal podocephalic glands. Strikingly, host plant dependent expression was evident for putative salivary proteins, and was further studied in detail by micro-array based genome-wide expression profiling. This meta-analysis revealed for the first time the salivary protein repertoire of a phytophagous chelicerate. The availability of this salivary proteome will assist in unraveling the molecular interface between phytophagous mites and their host plants, and may ultimately facilitate the development of mite-resistant crops. Furthermore, the technique used in this study is a time- and resource-efficient method to examine the salivary protein composition of other small arthropods for which saliva or salivary glands cannot be isolated easily. PMID- 27703044 TI - Older men with severe disc degeneration have more incident vertebral fractures the prospective MINOS cohort study. AB - OBJECTIVE: Data on the relationship between disc degeneration (DD) and fragility fractures in men are limited. The aim of this study was to prospectively analyse the risk of vertebral and non-vertebral fractures in men with thoracolumbar DD according to the severity of its radiological signs: disc space narrowing (DSN), osteophytes and endplate sclerosis. METHODS: Men >50 years of age (n = 765) had lateral spine radiographs and DXA and were monitored prospectively. We analysed the risk of incident vertebral (7.5 years) and non-vertebral fractures (10 years) in men according to the severity of DD. RESULTS: After adjustment for age and weight, BMD increased with increasing total DSN score, endplate sclerosis and osteophytosis. Over 7.5 years, 28 incident vertebral fractures occurred in 27 men. After adjustment for age, BMI, spine BMD, prior fractures and abdominal aortic calcifications, the vertebral fracture risk was 3-fold higher in the upper DSN quartile vs men without DSN. After adjustment for the same confounders, vertebral fracture risk was also nearly 3-fold higher in the upper DSN quartile vs the three lower quartiles combined. Over 10 years, 61 men sustained non vertebral fragility fractures. After adjustment for age, BMI, hip BMD, abdominal aortic calcifications and prior falls and fractures, the non-vertebral fracture risk decreased with increasing DSN score. The risk of non-vertebral fracture was half as high in men above the median total DSN score vs men below the median. CONCLUSION: In older men, severe DD is associated with higher BMD. Multilevel severe DSN is associated with higher vertebral fracture risk and lower non vertebral fracture risk. PMID- 27703043 TI - Low-anxiety rats are more sensitive to amphetamine in comparison to high-anxiety rats. AB - This study utilised the two injection protocol of sensitisation (TIPS) and the conditioned place preference test to validate and extend previous findings on the effects of amphetamine on positive reinforcement-related 50 kHz ultrasonic vocalisation (USV) in rats. We also examined changes in the expression of c-Fos and the NMDA receptor 2B (GluN2B) subunit, markers of neuronal activity and plasticity, in brain regions of rats in response to TIPS. We used low anxiety responsive (LR) and high anxiety-responsive (HR) rats, which are known to exhibit different fear-conditioned response strengths, different susceptibilities to amphetamine in the TIPS procedure and different amphetamine-dependent 50 kHz USV responses. The LR rats, compared to the HR rats, not only vocalised much more intensely but also spent significantly more time in the amphetamine-paired compartment. After the second dose of amphetamine, the LR rats exhibited more c Fos and GluN2B activation in layers II and III of the M1/M2 motor cortex area and prefrontal cortex (PRE, PRL, IL) and also presented with more GluN2B activation in the basal amygdala. These data reveal that HR and LR rats exhibit different levels of reactivity in the cortical-limbic pathway, which controls reward related motivational processes. These findings contribute to the general hypothesis that heterogeneity in emotional processes is one of the causes of sensitisation to amphetamine and drug addiction. PMID- 27703049 TI - Detection of Genomic DNA Damage from Radiated Nasopharyngeal Carcinoma Cells Using Surface-Enhanced Raman Spectroscopy (SERS). AB - Structural changes and chemical modifications in DNA during interactions with X ray radiation are still not clear within 48 h of incubation. We investigate genomic DNA from the radiated CNE2 cell line within 48 h of incubation using surface-enhanced Raman spectroscopy (SERS). Multivariate methods including principal component analysis (PCA) and random forest are proposed to explore the statistical significance before and after radiation. Our results show that intensities of several bands change after radiation, which indicates backbone damage and base-unstacking. Biological effects from DNA damage repairing process may be simultaneously stimulated and different from incubation time. Under doses of 10 Gy (with 24 and 48 h of incubation) and 20 Gy (with 48 h of incubation), the relative contents of C against T and A against G deviate obviously from the control level. Statistical results strengthen significantly the idea that modification in DNA bases is associated with the disruption of base-stacking in the DNA duplex. Our findings provide vital information for radiation-induced the DNA damage at the molecular level, which may provide insight into the effect and mechanism of anticarcinogens in tumor therapy.

Qualitative and quantitative investigation through this analytical technique can help elucidate the origin and evolution of meteoritic compounds as well as parent body processes without damaging or altering the investigated samples. PMID- 27703042 TI - The ICCAM platform study: An experimental medicine platform for evaluating new drugs for relapse prevention in addiction. Part B: fMRI description. AB - OBJECTIVES: We aimed to set up a robust multi-centre clinical fMRI and neuropsychological platform to investigate the neuropharmacology of brain processes relevant to addiction - reward, impulsivity and emotional reactivity. Here we provide an overview of the fMRI battery, carried out across three centres, characterizing neuronal response to the tasks, along with exploring inter-centre differences in healthy participants. EXPERIMENTAL DESIGN: Three fMRI tasks were used: monetary incentive delay to probe reward sensitivity, go/no-go to probe impulsivity and an evocative images task to probe emotional reactivity. A coordinate-based activation likelihood estimation (ALE) meta-analysis was carried out for the reward and impulsivity tasks to help establish region of interest (ROI) placement. A group of healthy participants was recruited from across three centres (total n=43) to investigate inter-centre differences. Principle observations: The pattern of response observed for each of the three tasks was consistent with previous studies using similar paradigms. At the whole brain level, significant differences were not observed between centres for any task. CONCLUSIONS: In developing this platform we successfully integrated neuroimaging data from three centres, adapted validated tasks and applied whole brain and ROI approaches to explore and demonstrate their consistency across centres. PMID- 27703051 TI - Application of SLICC classification criteria in undifferentiated connective tissue disease and evolution in systemic lupus erythematosus: analysis of a large monocentric cohort with a long-term follow-up. AB - Objectives The objectives of this study were to analyse the performance of the Systemic Lupus International Collaborating Clinics (SLICC) 2012 classification criteria for systemic lupus erythematosus (SLE) in a large cohort of undifferentiated connective tissue disease (UCTD) population at onset of the disease and during a long-term follow-up of 15 years (1999-2013) and to evaluate the transition from UCTD to SLE, according to American College of Rheumatology (ACR) 1997 and SLICC 2012 classification criteria. Methods A cohort of patients who met the classification criteria proposed by Mosca et al. for UCTD, were analysed. The SLICC 2012 classification criteria for SLE were retrospectively applied to each patient at the time of the diagnosis (T0) and also periodically re-applied and compared to ACR 1997 criteria at three different time points in the follow-up. Results 329 patients were enrolled. According to inclusion criteria at T0 no patient met the SLE/ACR criteria, whilst, retrospectively applying the SLE/SLICC criteria, 44 patients already satisfied this set of criteria for SLE. During the follow-up 23 new patients reached the SLE/SLICC criteria and 14 patients met the ACR criteria with a stable rate of progression to SLE over time. Acute or subacute skin rash, antiphospholipid antibody (aPL) positivity and serositis were the variables correlated to the evolution to SLE. Conclusions In our UCTD population, the application of SLICC classification criteria for SLE at disease onset allowed identification of a proportion of otherwise missed SLE cases; during follow-up, and compared with ACR criteria, SLICC criteria expanded the number of patients classifiable as SLE otherwise classified as UCTD. PMID- 27703052 TI - Disseminated cytomegalovirus infection complicating active treatment of systemic lupus erythematosus: an emerging problem. AB - Patients with systemic lupus erythematosus (SLE) often require immunosuppression to induce remission of active disease exacerbations. Over the past two decades, treatment modalities for this condition have emerged leading to improved morbidity from disease related outcomes. However, as a result, infection risks and patterns have changed, leading to higher rates of opportunistic infections among this population. We report four cases of cytomegalovirus (CMV) in patients with SLE who received immunosuppressive therapy, including pulse steroids, antimetabolites such as mycophenolate mofetil, and alkylating agents such as cyclophosphamide. We propose that given the rise in prevalence of CMV, there is a need for appropriate screening for this opportunistic pathogen and studies to determine the risks and benefits of prophylactic or preemptive treatment for this virus. PMID- 27703054 TI - Estimating shifts in diversification rates based on higher-level phylogenies. AB - Macroevolutionary studies recently shifted from only reconstructing the past state, i.e. the species phylogeny, to also infer the past speciation and extinction dynamics that gave rise to the phylogeny. Methods for estimating diversification dynamics are sensitive towards incomplete species sampling. We introduce a method to estimate time-dependent diversification rates from phylogenies where clades of a particular age are represented by only one sampled species. A popular example of this type of data is phylogenies on the genus- or family-level, i.e. phylogenies where one species per genus or family is included. We conduct a simulation study to validate our method in a maximum-likelihood framework. Further, this method has already been introduced into the Bayesian package MrBayes, which led to new insights into the evolution of Hymenoptera. PMID- 27703053 TI - Gestational weight gain in women with systemic lupus erythematosus. AB - Objective The objective of this study was to estimate the proportion of pregnant women with systemic lupus erythematosus meeting Institute of Medicine guidelines for gestational weight gain and determine correlates of adherence to guidelines. Methods Singleton, live births in the Hopkins Lupus Pregnancy Cohort 1987-2015 were included. Pre-pregnancy weight was the weight recorded 12 months prior to pregnancy/first trimester. Final weight was the last weight recorded in the third trimester. Adherence to Institute of Medicine guidelines (inadequate, adequate, or excessive) was based on pre-pregnancy body mass index. Fisher's exact test and analysis of variance determined factors associated with not meeting guidelines. Stepwise selection estimated predictors of gestational weight gain. Results Of the 211 pregnancies, 34%, 24% and 42% had inadequate, adequate and excessive gestational weight gain, respectively. In exploratory analyses, differences in Institute of Medicine adherence were observed by pre-pregnancy body mass index, race, elevated creatinine during pregnancy and pre-pregnancy blood pressure. Odds of inadequate and excessive gestational weight gain increased 12% with each 1 kg/m2 increase in pre-pregnancy body mass index. Lower maternal education was associated with increased odds of inadequate and excessive gestational weight gain. Conclusions As in the general population, most women with systemic lupus erythematosus did not meet Institute of Medicine guidelines. Our results identified predictors of gestational weight gain to aid in targeted interventions to improve guideline adherence in this population. PMID- 27703055 TI - Long-distance autumn migration across the Sahara by painted lady butterflies: exploiting resource pulses in the tropical savannah. AB - The painted lady, Vanessa cardui, is a migratory butterfly that performs an annual multi-generational migration between Europe and North Africa. Its seasonal appearance south of the Sahara in autumn is well known and has led to the suggestion that it results from extremely long migratory flights by European butterflies to seasonally exploit the Sahel and the tropical savannah. However, this possibility has remained unproven. Here, we analyse the isotopic composition of butterflies from seven European and seven African countries to provide new support for this hypothesis. Each individual was assigned a geographical natal origin, based on its wing stable hydrogen isotope (delta2Hw) value and a predicted delta2Hw basemap for Europe and northern Africa. Natal assignments of autumn migrants collected south of the Sahara confirmed long-distance movements (of 4000 km or more) starting in Europe. Samples from Maghreb revealed a mixed origin of migrants, with most individuals with a European origin, but others having originated in the Sahel. Therefore, autumn movements are not only directed to northwestern Africa, but also include southward and northward flights across the Sahara. Through this remarkable behaviour, the productive but highly seasonal region south of the Sahara is incorporated into the migratory circuit of V. cardui. PMID- 27703056 TI - Yawn duration predicts brain weight and cortical neuron number in mammals. AB - Research indicates that the motor action pattern of yawning functions to promote cortical arousal and state change through enhanced intracranial circulation and brain cooling. Because the magnitude of this response likely corresponds to the degree of neurophysiological change, we hypothesized that interspecies variation in yawn duration would correlate with underlying neurological differences. Using openly accessible data, we show that both the mean and variance in yawn duration are robust predictors of mammalian brain weight and cortical neuron number (rho values > 0.9). Consistent with these effects, primates tend to have longer and more variable yawn durations compared with other mammals. Although yawning has long been considered a stereotyped action pattern, these findings reveal substantial variation in this response and highlight the importance of measuring yawn duration in future research. PMID- 27703057 TI - Increase in disaster-related deaths: risks and social impacts of evacuation. AB - In Fukushima Prefecture, disaster-related death is a social problem for individuals who were forced to leave their hometowns as a result of the Great East Japan Earthquake and the accident at Fukushima Daiichi nuclear power plant. Disaster-related death is caused by stress, exhaustion, and worsening of pre existing illnesses due to evacuation. The number of disaster-related deaths has reached almost 2000, and continues to rise. Prolonged uncertainty and deteriorating living conditions suggest no end to such deaths, although response measures have been taken to improve the situation. It is said that insufficient response measures were taken, in particular, during the transitional period between the emergency phase and the reconstruction phase. There is a need to apply the lessons learned in planning for evacuation after a nuclear hazard, considering radiological protection as well as risks associated with evacuation. PMID- 27703059 TI - Health Policy Initiatives for African American Women Veterans. AB - America's military has experienced great changes in the demographic makeup of its veterans over the past few decades. In fact, the fastest growing group in the U.S. military is women. This demographic trend has also brought new challenges in dealing with gender issues, something that the Veterans Health Administration (VHA) has only recently begun to acknowledge. The VHA has responded in several ways to gender issues in health care and health outcomes. And, although the VHA is dealing with multiple gender matters, this article will focus on initiatives to combat cardiovascular disease (CVD) in women veterans. It will also highlight the significance of CVD, both to women veterans in general and to African American women veterans specifically. The article concludes with a discussion of VHA activities and strategies to improve the cardiovascular health of African American women veterans. PMID- 27703058 TI - Distribution of ESBLs, AmpC beta-lactamases and carbapenemases among Enterobacteriaceae isolates causing intra-abdominal and urinary tract infections in the Asia-Pacific region during 2008-14: results from the Study for Monitoring Antimicrobial Resistance Trends (SMART). AB - OBJECTIVES: To investigate the antimicrobial resistance and assess the molecular characteristics of beta-lactamases (ESBLs, AmpC beta-lactamases and carbapenemases) among Enterobacteriaceae isolates that caused intra-abdominal infections (IAIs) in patients hospitalized in the Asia-Pacific region during 2008 14. METHODS: Multiplex PCR was used to detect the specific types of beta lactamase in 2893 isolates with MICs of ertapenem >0.5 mg/L. In-hospital acquisition times for most isolates were also delineated. RESULTS: Among 2728 (94.3%) isolates proven with beta-lactamase production, the rates of non susceptibility to imipenem were low (average = 7.9%) among IAI Enterobacteriaceae isolates from all Asia-Pacific countries except Vietnam (17.7%) and the Philippines (10.2%). A stepwise and significant increase in annual rates of carbapenemase production among these isolates was noted. CTX-M-15 and CTX-M-14 were the dominant ESBL variants in most IAI Enterobacteriaceae species. The most abundant AmpC beta-lactamase variants were blaCMY-2 among isolates of Escherichia coli and blaDHA-1 among isolates of Klebsiella pneumoniae. In addition, the IAI Enterobacteriaceae isolates harbouring a blaCMY-2 or blaDHA-1 allele were associated with high community-acquired rates (38.0% and 42.6%, respectively). AmpC ACT and MIR variants were mostly detected in Enterobacter species. The blaNDM-1,4,5,7-harbouring isolates of E. coli, K. pneumoniae and Enterobacter cloacae were most commonly identified among IAI isolates from Vietnam and the Philippines. Also of note, blaOXA-48-harbouring IAI Enterobacteriaceae isolates were detected exclusively in Vietnam. CONCLUSIONS: The high resistance burden in Vietnam and the Philippines warrants aggressive control policies to combat the worsening trend in antimicrobial resistance among Enterobacteriaceae species causing IAIs. PMID- 27703061 TI - Olfactory Training Using Heavy and Light Weight Molecule Odors. AB - Background Repeated short-term exposure to odors is known to improve olfaction in patients with acquired olfactory dysfunction. The aim was to find out whether differences in molecular weight of odors used for olfactory training influences olfaction. We hypothesized a greater improvement following training with light weight molecule (LWM) odors. Methods A prospective study was performed in patients with posttraumatic (PTOL) and postviral olfactory loss (PVOL). Olfactory training was performed over a period of 5 months. One group ( n = 48) used four odors containing heavy weight molecules (HWM; >150 g/mol) and another ( n = 48) containing LWM (<150 g/mol). Olfaction was tested before and after the training using the Sniffin' Sticks test. Results Olfactory training was associated with olfactory improvement, with the improvement in PVOL patients being three times greater than that seen in the PTOL group. Compared with LWM training, HWM training was associated with a significantly greater improvement in Phenyl Ethyl Alcohol (PEA) threshold scores in PVOL patients; however, no such improvement could be shown for other subtests or in PTOL patients. Conclusion Overall, training was associated with olfactory improvement. With the exception of threshold scores in PVOL, there were no significant differences between LWM and HWM groups. PMID- 27703062 TI - Multivariate Associations Among Health-Related Fitness, Physical Activity, and TGMD-3 Test Items in Disadvantaged Children From Low-Income Families. AB - Motor skills are needed for physical development and may be linked to health related fitness and physical activity levels. No studies have examined the relationships among these constructs in large samples of disadvantaged children from low-income families using the Test for Gross Motor Development-3rd Edition (TGMD-3). The purpose of this study was to examine the multivariate associations among health-related fitness, physical activity, and motor skills assessed using the TGMD-3. Participants included 1460 school-aged children (730 boys, 730 girls; M age = 8.4 years, SD = 1.8 years) recruited from the K to sixth grades from three low-income schools. Health-related fitness was assessed using the FITNESSGRAM battery, physical activity was assessed using accelerometers and pedometers, and motor skills were assessed using the TGMD-3. Canonical correlations revealed statistically significant correlations between the Ball Skills and health-related fitness variates (Rc = 0.43, Rc2 = 17%, p < 0.001). Significant canonical coefficients in the Ball Skills variate included two-handed striking, dribbling, and catching, and significant canonical coefficients in the health-related fitness variate included body mass index and the progressive aerobic cardiovascular endurance run ( p < 0.01). Locomotor skills did not significantly correlate with health-related fitness or physical activity. Ball skills are related to health-related fitness in disadvantaged children from low income families. PMID- 27703060 TI - Quantitative assessment of parent vessel and distal intracranial hemodynamics following pipeline flow diversion. AB - Background Pipeline embolization devices (PEDs) are commonly used for endovascular treatment of cerebral aneurysms but can be associated with delayed ipsilateral intraparenchymal hemorrhage. Although intra-aneurysmal hemodynamic changes have been studied, parent vessel and intracranial hemodynamics after PED use are unknown. We examine the impact of flow diversion on parent artery and distal intracranial hemodynamics. Method Patients with internal carotid cerebral aneurysms treated with PED who had flow volume rate, flow velocities, pulsatility index, resistance index, Lindegaard ratio, and wall shear stress (WSS) obtained after treatment using quantitative magnetic resonance angiography were reviewed. Means were compared between ipsilateral and contralateral internal carotid artery (ICA) and middle cerebral artery (MCA) using paired t tests. Results A total of 18 patients were included. Mean flow volume rate was lower in the ipsilateral versus contralateral ICA ( p = 0.04) but tended to be higher in the ipsilateral versus contralateral MCA ( p = 0.08). Lindegaard ratio was higher ipsilateral to the PED in diastole ( p = 0.05). Although there was no significant difference in flow velocities, pulsatility or resistance indices, and WSS, the two cases in our cohort with hemorrhagic complications did display significant changes in MCA flows and MCA WSS. Conclusion PED placement appears to alter the elasticity of the stented ICA segment, with lower flows in the ipsilateral versus contralateral ICA. Conversely, MCA flows and MCA WSS are higher in the ipsilateral MCA among patients with hemorrhage after PED placement, suggesting the role of disrupted distal hemodynamics in delayed ipsilateral intraparenchymal hemorrhage. PMID- 27703063 TI - Speed of Reaction and Fighting Effectiveness in Elite Greco-Roman Wrestlers. AB - The purpose of the study was to determine the changes in simple reaction time and to define correlations between simple reaction time and technical and tactical actions performed by elite Greco-Roman wrestlers during a match. Twenty Greco Roman wrestlers (M age = 19.5 years, SD = 1.8) from the Wrestling Sports Centre in Radom participated in the study. Simple reaction time (including reaction time and movement time) before a match and after the first, the second, and the third round was analyzed. The wrestlers' reaction time and movement time changed in the course of performance. Wrestlers with higher sports achievements demonstrated a smaller decrement in simple reaction time and performed more technical and tactical actions during a match. The strongest correlations were observed between both reaction time and movement time and the number of technical and tactical actions performed during the last round. Quick reaction was a significant factor in determining the match outcome, which is revealed at submaximal intensity of the effort during a match. PMID- 27703064 TI - Physical and Functional Impairment During and After Hospitalization in Subjects With Severe COPD Exacerbation. AB - BACKGROUND: COPD exacerbations are frequent events that have a negative impact on the lives of patients. The aims of this study were to analyze physical and functional impairment during hospital stay in subjects hospitalized due to COPD exacerbation and to assess the physical and functional impact of hospitalization at a 1-month follow-up in patients with severe COPD. METHODS: This was a prospective observational study on a sample of 52 subjects hospitalized due to COPD exacerbation. The assessments were performed at baseline, discharge, and 1 month follow-up. The outcome measures were dyspnea, muscle strength, functional capacity, and postural steadiness. RESULTS: Quadriceps strength [1.036 (P = .043) kg mean difference] and the one-leg stance test [1.04 (P = .02) and 0.73 (P = .032) s mean difference right and left leg] showed significant impairment during hospitalization. Dyspnea perception improved significantly (P = .004) during hospitalization. Additionally, strength in the upper and lower limbs [4.04 (P = .002) and 1.23 (P = .038) kg mean difference], functional capacity [3.0 number of steps mean difference (P = .032)], and the one-leg stance test [2.12 (P = .006) and 0.53 (P = .047) s mean difference right and left leg] showed significant impairment 1-month follow-up. CONCLUSIONS: Hospitalization due to COPD exacerbation leads to physical and functional impairment in patients; impairment is greater at 1-month follow-up. It would be interesting to conduct physical therapy interventions to prevent the impairment. PMID- 27703065 TI - The prevalence of fatigue after stroke: A systematic review and meta-analysis. AB - BACKGROUND: Fatigue is a common and debilitating symptom after stroke. The last decade has seen rapid expansion of the research literature on post-stroke fatigue, but prevalence remains unclear. AIMS: To estimate post-stroke fatigue prevalence and to identify the contributing factors to fatigue, by conducting a systematic review and meta-analysis. SUMMARY OF REVIEW: We included all studies of adult stroke survivors that used a recognized assessment scale for fatigue (search date September 2014). Two reviewers independently reviewed all full texts for inclusion. Data were extracted by one reviewer and independently cross checked by a second. Risk of bias was evaluated using a critical appraisal tool. From an overall yield of 921 studies, 101 full text papers were screened, and 49 of these met inclusion criteria. The most widely used measure of fatigue was the Fatigue Severity Scale (n = 24 studies). Prevalence estimates at a cut-off score of > or >= 4 were available for 22 of these 24 studies (total n = 3491), and ranged from 25 to 85%. In random effects meta-analysis, the pooled prevalence estimate was 50% (95% CI 43-57%), with substantial heterogeneity (I2 = 94%). Neither depression status nor time point post-stroke explained the heterogeneity between studies. In post-hoc analysis, fatigue prevalence was found to be lower in the four Asian studies (35%; 95% CI 20-50; I2 = 96%). CONCLUSIONS: Our results confirm that fatigue is a widespread issue for stroke survivors, although it may be less prevalent in Asia. Further research is needed to explain the wide variability in prevalence estimates between studies.

AB - Atrial fibrillation is the world's most common sustained cardiac arrhythmia and is associated with a significantly increased risk of stroke. The global burden of atrial fibrillation is rising, commensurate with the ageing population. Well controlled vitamin K antagonist-based anticoagulation has been shown to reduce the risk of stroke secondary to atrial fibrillation by two-thirds. However, patients with atrial fibrillation have frequently been denied anticoagulation because of a variety of perceived risks related to bleeding, falls, chronological age, and poor compliance. Even when vitamin K antagonists are used, maximum benefit and safety are only delivered when high quality control of therapy (TTR > 70%) is achieved, which has proven remarkably difficult in many health-care systems and amongst many patient groups. The non-vitamin K antagonist oral anticoagulants (NOACs) offer solutions to many of the challenges of achieving widespread, safe, and effective anticoagulation for stroke prophylaxis in atrial fibrillation, yet their uptake into routine clinical practice remains variable. The evidence supporting their more widespread use to overcome the challenges of stroke prophylaxis for atrial fibrillation is reviewed in this article. PMID- 27703067 TI - Fibrin gel versus papain gel in the healing of chronic venous ulcers: A double blind randomized controlled trial. AB - Objectives Compare the efficacy and safety of fibrin gel to 8% papain gel for wound dressing of venous ulcers. Method Patients with chronic venous ulcers were randomly assigned to one in three groups: Group 1-fibrin gel; Group 2-8% papain gel; Group 3-carbopol gel (control). Patients were seen every 15 days during 2 months, verifying reduction of the ulcer area, local infection, exudation, and epithelization. All serious or nonserious adverse events were recorded. Results Fifty-five patients (total of 63 ulcers) were randomly distributed in three groups (G1 = 21; G2 = 19; G3 = 23). No patient was excluded or discontinued treatment throughout the study. The areas of the ulcers were similarly reduced in all groups (14.3%, 21.1%, and 30.4% in groups 1, 2, and 3, respectively), and all had significant reduction in exudation and contamination. Conclusion The data demonstrate that neither fibrin gel nor papain gel were able to improve the process of ulcer-healing, as compared to control. PMID- 27703068 TI - Hospital incidence and annual rates of hospitalization for venous thromboembolic disease in France and the USA. AB - Objective The study was designed to describe the hospital incidences and annual hospitalization rates for venous thromboembolic disease by age and sex in France and the United States on the closest possible methodological bases. Methods French statistics are from the PMSI MCO (Programme de medicalisation des systeme d'information de medecine, chirurgie et obstetrique (French national hospital discharge register)) national database. These are compiled for each calendar year by collating resume de sortie anonymise (RSA, anonymous discharge summary) files forwarded and validated by health establishments with admissions in medicine, surgery, obstetrics, and odontology. They are compared to the data issued from the US National Hospital Discharge Survey which is equivalent to the PMSI in France and uses the International Classification of Diseases-9 for encoding the data. These data were published in the Morbidity, Mortality Weekly Report of the Centre for Disease Control. Results In the US, 547,996 hospital stays involve venous thromboembolic diseases, 348,558 deep venous thrombosis (DVT), and 277,549 pulmonary embolism (PE). Of these 78,511, or 14%, include a diagnosis of both DVT and PE. The hospital incidence of venous thromboembolic disease is 1.4%, DVT 0.9%, and PE 0.7%. In France, of the 26,658,228 annual hospital stays, 273,931 include venous thromboembolic disease, 179,286 DVT, and 139,345 PE while 44,700, i.e. 16.3%, include both DVT and PE. The hospital incidence of venous thromboembolic disease is thus 1.0%, DVT 0.6%, and PE 0.5%. The overall annual hospitalization rates for venous thromboembolic disease, DVT, and PE are respectively 274, 179, and 139 per 100,000 inhabitants in France and 239, 146, and 121 per 100,000 inhabitants in the US. Conclusion Venous thromboembolic diseases occur in France and the US in 1% of all hospital stays and are responsible for an annual hospitalization rate that exceeds 200 per 100,000. The scale of these annual incidences should prompt us to question the quality of prevention put in place and/or its efficacy. PMID- 27703069 TI - Secondhand Smoke Exposure 7 Years After an Indoor Smoke-Free Law. AB - PURPOSE: To examine locations of secondhand smoke (SHS) exposure among nonsmokers, 7 years after a statewide smoke-free policy. DESIGN: Data collected via statewide, random digit dial telephone survey. Response rates were 64.7% for landline and 73.5% for cell phone. SETTING: Minnesota, 2014. PARTICIPANTS: Representative sample of 7887 nonsmoking adults. MEASURES: Self-reported locations of SHS exposure and opinions on smoke-free restrictions. ANALYSIS: Descriptive statistics and logistic regression. RESULTS: A total of 35.5% of nonsmokers reported SHS exposure in the past 7 days. The greatest proportion of exposure occurred in community settings (31.7%) followed by cars (6.9%) and in the home (3.2%). Young adults were more likely to be exposed in a home or car than older adults. Nonsmokers living with a smoker were 39.6 (20.6-75.8) times more likely to be exposed to SHS in their home and 5.3 (4.1-6.8) times more likely to be exposed in a car, compared to those who did not live with a smoker. CONCLUSION: SHS exposure continues after comprehensive smoke-free policies restricted it from public places. Disparities in exposure rates exist for those who live with a smoker, are young, and have low incomes. Findings suggest the need for additional policies that will have the greatest public health benefit. PMID- 27703070 TI - Cap0037, a Novel Global Regulator of Clostridium acetobutylicum Metabolism. AB - : An operon comprising two genes, CA_P0037 and CA_P0036, that encode proteins of unknown function that were previously shown to be highly expressed in acidogenic cells and repressed in solventogenic and alcohologenic cells is located on the pSOL1 megaplasmid of Clostridium acetobutylicum upstream of adhE2 A CA_P0037::int (189/190s) mutant in which an intron was inserted at position 189/190 in the sense strand of CA_P0037 was successfully generated by the Targetron technique. The resultant mutant showed significantly different metabolic flux patterns in acidogenic (producing mainly lactate, butyrate, and butanol) and alcohologenic (producing mainly butyrate, acetate, and lactate) chemostat cultures but not in solventogenic or batch cultures. Transcriptomic investigation of the CA_P0037::int (189/190s) mutant showed that inactivation of CA_P0037 significantly affected the expression of more than 258 genes under acidogenic conditions. Surprisingly, genes belonging to the Fur regulon, involved in iron transport (CA_C1029-CA_C1032), or coding for the main flavodoxin (CA_C0587) were the most significantly expressed genes under all conditions, whereas fur (coding for the ferric uptake regulator) gene expression remained unchanged. Furthermore, most of the genes of the Rex regulon, such as the adhE2 and ldhA genes, and of the PerR regulon, such as rbr3A-rbr3B and dfx, were overexpressed in the mutant. In addition, the whole CA_P0037-CA_P0036 operon was highly expressed under all conditions in the CA_P0037::int (189/190s) mutant, suggesting a self-regulated expression mechanism. Cap0037 was shown to bind to the CA_P0037-CA_P0036 operon, sol operon, and adc promoters, and the binding sites were determined by DNA footprinting. Finally, a putative Cap0037 regulon was generated using a bioinformatic approach. IMPORTANCE: Clostridium acetobutylicum is well-known for its ability to produce solvents, especially n-butanol. Understanding the regulatory network of C. acetobutylicum will be crucial for further engineering to obtain a strain capable of producing n-butanol at high yield and selectivity. This study has discovered that the Cap0037 protein is a novel regulator of C. acetobutylicum that drastically affects metabolism under both acidogenic and alcohologenic fermentation conditions. This is pioneering work for further determining the regulatory mechanism of Cap0037 in C. acetobutylicum and studying the role of proteins homologous to Cap0037 in other members of the phylum Firmicutes. PMID- 27703071 TI - Next-Generation High-Throughput Functional Annotation of Microbial Genomes. AB - Host infection by microbial pathogens cues global changes in microbial and host cell biology that facilitate microbial replication and disease. The complete maps of thousands of bacterial and viral genomes have recently been defined; however, the rate at which physiological or biochemical functions have been assigned to genes has greatly lagged. The National Institute of Allergy and Infectious Diseases (NIAID) addressed this gap by creating functional genomics centers dedicated to developing high-throughput approaches to assign gene function. These centers require broad-based and collaborative research programs to generate and integrate diverse data to achieve a comprehensive understanding of microbial pathogenesis. High-throughput functional genomics can lead to new therapeutics and better understanding of the next generation of emerging pathogens by rapidly defining new general mechanisms by which organisms cause disease and replicate in host tissues and by facilitating the rate at which functional data reach the scientific community. PMID- 27703073 TI - Mycobacteriophages as Incubators for Intein Dissemination and Evolution. AB - : Inteins are self-splicing protein elements that are mobile at the DNA level and are sporadically distributed across microbial genomes. Inteins appear to be horizontally transferred, and it has been speculated that phages may play a role in intein distribution. Our attention turns to mycobacteriophages, which infect mycobacteria, where both phage and host harbor inteins. Using bioinformatics, mycobacteriophage genomes were mined for inteins. This study reveals that these mobile elements are present across multiple mycobacteriophage clusters and are pervasive in certain genes, like the large terminase subunit TerL and a RecB-like nuclease, with the majority of intein-containing genes being phage specific. Strikingly, despite this phage specificity, inteins localize to functional motifs shared with bacteria, such that intein-containing genes have similar roles, like hydrolase activity and nucleic acid binding, indicating a global commonality among intein-hosting proteins. Additionally, there are multiple insertion points within active centers, implying independent invasion events, with regulatory implications. Several phage inteins were shown to be splicing competent and to encode functional homing endonucleases, important for mobility. Further, bioinformatic analysis supports the potential for phages as facilitators of intein movement among mycobacteria and related genera. Analysis of catalytic intein residues finds the highly conserved penultimate histidine inconsistently maintained among mycobacteriophages. Biochemical characterization of a noncanonical phage intein shows that this residue influences precursor accumulation, suggesting that splicing has been tuned in phages to modulate generation of important proteins. Together, this work expands our understanding of phage-based intein dissemination and evolution and implies that phages provide a context for evolution of splicing-based regulation. IMPORTANCE: Inteins are mobile protein splicing elements found in critical genes across all domains of life. Mycobacterial inteins are of particular interest because of their occurrence in pathogenic species, such as Mycobacterium tuberculosis and Mycobacterium leprae, which harbor inteins in important proteins. We have discovered a similarity in activities of intein-containing proteins among mycobacteriophages and their intein-rich actinobacterial hosts, with implications for both posttranslational regulation by inteins and phages participating in horizontal intein transfer. Our demonstration of multiple insertion points within active centers of phage proteins implies independent invasion events, indicating the importance of intein maintenance at specific functional sites. The variable conservation of a catalytic splicing residue, leading to profoundly altered splicing rates, points to the regulatory potential of inteins and to mycobacteriophages playing a role in intein evolution. Collectively, these results suggest inteins as posttranslational regulators and mycobacteriophages as both vehicles for intein distribution and incubators for intein evolution. PMID- 27703072 TI - LasR Variant Cystic Fibrosis Isolates Reveal an Adaptable Quorum-Sensing Hierarchy in Pseudomonas aeruginosa. AB - : Chronic Pseudomonas aeruginosa infections cause significant morbidity in patients with cystic fibrosis (CF). Over years to decades, P. aeruginosa adapts genetically as it establishes chronic lung infections. Nonsynonymous mutations in lasR, the quorum-sensing (QS) master regulator, are common in CF. In laboratory strains of P. aeruginosa, LasR activates transcription of dozens of genes, including that for another QS regulator, RhlR. Despite the frequency with which lasR coding variants have been reported to occur in P. aeruginosa CF isolates, little is known about their consequences for QS. We sequenced lasR from 2,583 P. aeruginosa CF isolates. The lasR sequences of 580 isolates (22%) coded for polypeptides that differed from the conserved LasR polypeptides of well-studied laboratory strains. This collection included 173 unique lasR coding variants, 116 of which were either missense or nonsense mutations. We studied 31 of these variants. About one-sixth of the variant LasR proteins were functional, including 3 with nonsense mutations, and in some LasR-null isolates, genes that are LasR dependent in laboratory strains were nonetheless expressed. Furthermore, about half of the LasR-null isolates retained RhlR activity. Therefore, in some CF isolates the QS hierarchy is altered such that RhlR quorum sensing is independent of LasR regulation. Our analysis challenges the view that QS-silent P. aeruginosa is selected during the course of a chronic CF lung infection. Rather, some lasR sequence variants retain functionality, and many employ an alternate QS strategy involving RhlR. IMPORTANCE: Chronic Pseudomonas aeruginosa infections, such as those in patients with the genetic disease cystic fibrosis, are notable in that mutants with defects in the quorum-sensing transcription factor LasR frequently arise. In laboratory strains of P. aeruginosa, quorum sensing activates transcription of dozens of genes, many of which encode virulence factors, such as secreted proteases and hydrogen cyanide synthases. In well-studied laboratory strains, LasR-null mutants have a quorum-sensing-deficient phenotype. Therefore, the presence of LasR variants in chronic infections has been interpreted to indicate that quorum-sensing-regulated products are not important for those infections. We report that some P. aeruginosa LasR variant clinical isolates are not LasR-null mutants, and others have uncoupled a second quorum-sensing system, the RhlR system, from LasR regulation. In these uncoupled isolates, RhlR independently activates at least some quorum-sensing-dependent genes. Our findings suggest that quorum sensing plays a role in chronic P. aeruginosa infections, despite the emergence of LasR coding variants. PMID- 27703074 TI - Phosphorylation of Golgi Peripheral Membrane Protein Grasp65 Is an Integral Step in the Formation of the Human Cytomegalovirus Cytoplasmic Assembly Compartment. AB - : Human cytomegalovirus (HCMV) is the largest member of the Herpesviridae and represents a significant cause of disease. During virus replication, HCMV alters cellular functions to facilitate its replication, including significant reorganization of the secretory and endocytic pathways of the infected cell. A defining morphologic change of the infected cell is the formation of a membranous structure in the cytoplasm that is designated the virion assembly compartment (AC), which consists of virion structural proteins surrounded by cellular membranes. The loss of normal Golgi compartment morphology and its relocalization from a juxtanuclear ribbonlike structure to a series of concentric rings on the periphery of the AC represents a readily recognized reorganization of cellular membranes in the HCMV-infected cell. Although trafficking of viral proteins to this compartment is required for the assembly of infectious virions, the functional significance of the reorganization of intracellular membranes like the Golgi membranes into the AC in the assembly of infectious virus remains understudied. In this study, we determined that Golgi membrane ribbon fragmentation increased during the early cytoplasmic phase of virion assembly and that Golgi membrane fragmentation in infected cells was dependent on the phosphorylation of an integral cis-Golgi protein, Grasp65. Inhibition of Golgi membrane fragmentation and of its reorganization into the AC resulted in decreased production of infectious particles and alteration of the incorporation of an essential protein into the envelope of the mature virion. These results demonstrated the complexity of the virus-host cell interactions required for efficient assembly of this large DNA virus. IMPORTANCE: The human cytomegalovirus (HCMV)-induced reorganization of intracellular membranes that is required for the formation of the viral assembly compartment (AC) has been an area of study over the last 20 years. The significance of this virus-induced structure has been evinced by the results of several studies which showed that relocalization of viral proteins to the AC was required for efficient assembly of infectious virus. In this study, we have identified a mechanism for the fragmentation of the Golgi ribbon in the infected cell en route to AC morphogenesis. Identification of this fundamental process during HCMV replication allowed us to propose that the functional role of Golgi membrane reorganization during HCMV infection was the concentration of viral structural proteins and subviral structures into a single intracellular compartment in order to facilitate efficient protein-protein interactions and the virion protein trafficking required for the assembly of this large and structurally complex virus. PMID- 27703075 TI - Collapse of Insect Gut Symbiosis under Simulated Climate Change. AB - : Global warming impacts diverse organisms not only directly but also indirectly via other organisms with which they interact. Recently, the possibility that elevated temperatures resulting from global warming may substantially affect biodiversity through disrupting mutualistic/parasitic associations has been highlighted. Here we report an experimental demonstration that global warming can affect a pest insect via suppression of its obligate bacterial symbiont. The southern green stinkbug Nezara viridula depends on a specific gut bacterium for its normal growth and survival. When the insects were reared inside or outside a simulated warming incubator wherein temperature was controlled at 2.5 degrees C higher than outside, the insects reared in the incubator exhibited severe fitness defects (i.e., retarded growth, reduced size, yellowish body color, etc.) and significant reduction of symbiont population, particularly in the midsummer season, whereas the insects reared outside did not. Rearing at 30 degrees C or 32.5 degrees C resulted in similar defective phenotypes of the insects, whereas no adult insects emerged at 35 degrees C. Notably, experimental symbiont suppression by an antibiotic treatment also induced similar defective phenotypes of the insects, indicating that the host's defective phenotypes are attributable not to the heat stress itself but to the suppression of the symbiont population induced by elevated temperature. These results strongly suggest that high temperature in the midsummer season negatively affects the insects not directly but indirectly via the heat-vulnerable obligate bacterial symbiont, which highlights the practical relevance of mutualism collapse in this warming world. IMPORTANCE: Climate change is among the biggest environmental issues in the contemporary world, and its impact on the biodiversity and ecosystem is not only of scientific interest but also of practical concern for the general public. On the basis of our laboratory data obtained under strictly controlled environmental conditions and our simulated warming data obtained in seminatural settings (elevated 2.5 degrees C above the normal temperature), we demonstrate here that Nezara viridula, the notorious stinkbug pest, suffers serious fitness defects in the summer season under the simulated warming conditions, wherein high temperature acts on the insect not directly but indirectly via suppression of its obligate gut bacterium. Our finding highlights that heat-susceptible symbionts can be the "Achilles' heel" of symbiont-dependent organisms under climate change conditions. PMID- 27703077 TI - The Appraisal of Self-Care Agency Scale-Revised (ASAS-R): Reliability and Validity Among Older Chinese People. AB - The study aimed to test the reliability and validity of the Chinese version of the Appraisal of Self-Care Agency Scale-Revised (ASAS-R-CHI). A cross-sectional design was used to conduct this study, and the sample consisted of 1,219 older people, collected by a demographic questionnaire, ASAS-R-CHI and the Exercise of Self-Care Agency (ESCA) scale. The Cronbach's alpha (alpha) of ASAS-R-CHI was .79, the test-retest correlation was 0.95, and the item-to-total correlations ranged from r = .41 to r = .74. Exploratory factor analysis (EFA) resulted in three factors that explained 65.31% of the total variance; all 15 items had strong factor loadings ranging from 0.54 to 0.91. Confirmatory factor analysis (CFA) indicated the three-factor solution of ASAS-R-CHI had a good fit (x2,chi square/degree of freedom [CMIN/DF] = 2.61, goodness of fitness index [GFI] = 0.93, adjusted goodness of fit index [AGFI] = 0.92,, comparative fit index [CFI = 0.92], Tucker Lewis index [TLI] = 0.91, root mean square error of approximation [RMSEA] = 0.04, root mean residual [RMR] = 0.02, P-value for test of close fit [PCLOSE] = 0.68). ASAS-R-CHI is a short, reliable, and valid instrument for measuring self-care agency among Chinese older adults. PMID- 27703076 TI - Broadly Neutralizing Hemagglutinin Stalk-Specific Antibodies Induce Potent Phagocytosis of Immune Complexes by Neutrophils in an Fc-Dependent Manner. AB - : Broadly neutralizing antibodies that recognize the conserved hemagglutinin (HA) stalk have emerged as exciting new biotherapeutic tools to combat seasonal and pandemic influenza viruses. Our general understanding of the mechanisms by which stalk-specific antibodies achieve protection is rapidly evolving. It has recently been demonstrated that broadly neutralizing HA stalk-specific IgG antibodies require Fc-Fcgamma receptor (FcgammaR) interactions for optimal protection in vivo Here we examine the neutrophil effector functions induced by stalk-specific antibodies. As the most abundant subset of blood leukocytes, neutrophils represent a critical innate effector cell population and serve an instrumental role in orchestrating downstream adaptive responses to influenza virus infection. Yet, the interplay of HA stalk-specific IgG, Fc-FcgammaR engagement, and neutrophils has remained largely uncharacterized. Using an in vitro assay to detect the production of reactive oxygen species (ROS), we show that human and mouse monoclonal HA stalk-specific IgG antibodies are able to induce the production of ROS by neutrophils, while HA head-specific antibodies do not. Furthermore, our results indicate that the production of ROS is dependent on Fc receptor (FcR) engagement and phagocytosis. We went on to assess the ability of monoclonal HA stalk-specific IgA antibodies to induce ROS. Consistent with our findings for monoclonal IgGs, only HA stalk-specific IgA antibodies elicited ROS production by neutrophils. This induction is dependent on the engagement of FcalphaR1. Taken together, our findings describe a novel FcR-dependent effector function induced by HA stalk-specific IgG and IgA antibodies, and importantly, our studies shed light on the mechanisms by which HA stalk-specific antibodies achieve protection. IMPORTANCE: The present study provides evidence that broadly neutralizing HA stalk-specific antibodies induce downstream Fc-mediated neutrophil effector functions. In addition to their ability to neutralize, this class of antibodies has been shown to rely on Fc-Fc receptor interactions for optimal protection in vivo Curiously, neutralizing antibodies that bind the HA head domain do not require such interactions. Our findings build on these previous observations and provide a more complete picture of the relationship between stalk-specific antibodies and cells of the innate immune compartment. Furthermore, our data suggest that the ability of HA stalk-specific antibodies to mediate Fc-Fc receptor engagement is epitope dependent. Overall, this work will inform the rational design of improved influenza virus vaccines and therapeutics. PMID- 27703078 TI - The Influence of Social Structure on Cancer Pain and Quality of Life. AB - The aim of this study was to investigate whether social structure is associated with cancer pain and quality of life using the Social Structure and Personality Research Framework. This study was a secondary analysis of data from 480 cancer patients. The measurements included socioeconomic variables, self-reported cancer pain using the McGill Pain Questionnaire-Short Form (MPQ-SF), and quality of life measured using the Functional Assessment of Cancer Therapy Scale (FACT-G). The data were analyzed using moderated multiple regression. Cancer pain and quality of life differed significantly with income. The associations between income and pain and quality of life were significant only for the high education group (>= partial college), and these associations were greater for Caucasians than for their counterparts ( p < .05). When developing interventions, nurses should consider the influence of socioeconomic variables on pain and quality of life while considering possible moderating factors such as education. PMID- 27703079 TI - Formation and psychometric evaluation of a health-related quality of life instrument for children living with HIV in India. AB - In-depth interviews and focus group discussions were conducted to inform the development of an instrument to measure the health-related quality of life of children living with HIV. The QOL-CHAI instrument consists of four generic core scales of the "Pediatric Quality of Life Inventory" and two HIV-targeted scales "symptoms" and "discrimination." A piloting exercise involving groups of children living with HIV and HIV-negative children born to HIV-infected parents provided evidence for the acceptable psychometric properties and usability of the instrument. It is expected that the QOL-CHAI can serve well as a brief, standardized, and culturally appropriate instrument for assessing health-related quality of life of Indian children living with HIV. PMID- 27703080 TI - A Perspective on the Kinetics of Covalent and Irreversible Inhibition. AB - The clinical and commercial success of covalent drugs has prompted a renewed and more deliberate pursuit of covalent and irreversible mechanisms within drug discovery. A covalent mechanism can produce potent inhibition in a biochemical, cellular, or in vivo setting. In many cases, teams choose to focus on the consequences of the covalent event, defined by an IC50 value. In a biochemical assay, the IC50 may simply reflect the target protein concentration in the assay. What has received less attention is the importance of the rate of covalent modification, defined by kinact/KI. The kinact/KI is a rate constant describing the efficiency of covalent bond formation resulting from the potency (KI) of the first reversible binding event and the maximum potential rate (kinact) of inactivation. In this perspective, it is proposed that the kinact/KI should be employed as a critical parameter to identify covalent inhibitors, interpret structure-activity relationships (SARs), translate activity from biochemical assays to the cell, and more accurately define selectivity. It is also proposed that a physiologically relevant kinact/KI and an (unbound) AUC generated from a pharmacokinetic profile reflecting direct exposure of the inhibitor to the target protein are two critical determinants of in vivo covalent occupancy. A simple equation is presented to define this relationship and improve the interpretation of covalent and irreversible kinetics. PMID- 27703081 TI - Development of Cell-Defined Lentivirus-Based Microarray for Mammalian Cells. AB - Although reverse transfection cell microarray (RTCM) is a powerful tool for mammalian cell studies, the technique is not appropriate for cells that are difficult to transfect. The lentivirus-infected cell microarray (LICM) technique was designed to improve overall efficiency. However, LICM presents new challenges because individual lentiviral particles can spread through the cell population, leading to cross-contamination. Therefore, we designed a cell-defined lentivirus microarray (CDLM) technique using cell-friendly biomaterials that are controlled by cell attachment timing. We selected poly-l-lysine (PLL) with Matrigel as the best combination of biomaterials for cell-defined culture. We used 2 uL PLL to determine by titration the optimum concentration required (0.04% stock, 0.005% final concentration). We also determined the optimum concentration of 10 uL of lentivirus particles for maximum reverse infection efficiency (1 * 108 infectious units [IFU]/mL stock, 62.5% final concentration) and established the best combination of components for the lentivirus mixture (10 uL of lentivirus particles and 2 uL each of siGLO Red dye, Matrigel, and 0.04% PLL). Finally, we validated both the effect of reverse infection in various cell lines and lentivirus spot activity in CDLM by storage period. This method provides an effective lentivirus-infected cell microarray for large-scale gene function studies. PMID- 27703082 TI - Fluorescent Parkin Cell-Based Assay Development for the Screening of Drugs against Parkinson Disease. AB - Parkinson disease (PD) is a prevalent neurodegenerative disease characterized by selective degeneration of dopaminergic neurons in the substantia nigra, causing tremor and motor impairment. Parkin protein, whose mutants are the cause of Parkinson disease type 2 (PARK2), has been mechanistically linked to the regulation of apoptosis and the turnover of damaged mitochondria. Several studies have implicated aberrant mitochondria as a key contributor to the development of PD. In the attempt to discover new drugs, high-content cell-based assays are becoming more important to mimic the nature of biological processes and their diversifications in diseases and will be essential for lead identification and the optimization of therapeutic candidates. We have developed a novel fluorescence cell-based assay for high-content screening to find compounds that can promote the mitochondrial localization of Parkin without severe mitochondrial damage induction. In this work, this model was used to screen a library of 1280 compounds. After the screening campaign, the positive compounds were chosen for further testing, based on the strength of the initial response and lack of cytotoxicity. These results indicated that this Parkin cell-based assay is a robust (Z' > 0.5) and valid strategy to test potential candidates for preclinical studies.

PMID- 27703085 TI - White Matter Microstructure Improves Stroke Risk Prediction in the General Population. AB - BACKGROUND AND PURPOSE: The presence of subclinical vascular brain disease, including white matter lesions and lacunar infarcts, substantially increases the risk of clinical stroke. White matter microstructural integrity is considered an earlier, potentially better, marker of the total burden of vascular brain disease. Its association with risk of stroke, a focal event, remains unknown. METHODS: From the population-based Rotterdam Study, 4259 stroke-free participants (mean age: 63.6 years, 55.6% women) underwent brain magnetic resonance imaging, including diffusion magnetic resonance imaging, between 2006 and 2011. All participants were followed up for incident stroke until 2013. Cox proportional hazards models were used to associate markers of the microstructure of normal appearing white matter with risk of stroke, adjusting for age, sex, white matter lesion volume, lacunar infarcts, and additionally for cardiovascular risk factors. Finally, we assessed the predictive value of white matter microstructural integrity for stroke beyond the Framingham Stroke Risk Profile. RESULTS: During 18 476 person-years of follow-up, 58 people experienced a stroke. Both lower fractional anisotropy and higher MD increased risk of stroke, independent of age, sex, cardiovascular risk factors, white matter lesion volume, and lacunar infarcts (hazard ratio per SD increase in: fractional anisotropy: 0.75 [95% confidence interval, 0.57-0.98] and MD: 1.50 [95% confidence interval, 1.08-2.09]). MD improved stroke prediction beyond the Framingham Stroke Risk Profile (continuous net reclassification improvement: 0.52 [95% confidence interval, 0.24-0.81]). CONCLUSIONS: Future stroke is predicted not only by prevalent vascular lesions but also by subtle alterations in the microstructure of normal-appearing white matter. Inclusion of this effect in risk prediction models produces a significant advantage in stroke prediction compared with the existing Framingham Stroke Risk Profile. PMID- 27703086 TI - Emerging Risk Factors for Recurrent Vascular Events in Patients With Embolic Stroke of Undetermined Source. AB - BACKGROUND AND PURPOSE: Underlying embolic causes diagnosed by transesophageal echocardiography could be implicated in mechanisms of embolic stroke of undetermined source. We aimed to explore factors, including underlying embolic causes, related to recurrent vascular events in embolic stroke of undetermined source. METHODS: Patients who fulfilled the diagnostic criteria for embolic stroke of undetermined source and whose potential embolic sources were examined by transesophageal echocardiography were included. Recurrent vascular events, including ischemic stroke, cardiovascular and peripheral artery diseases, and vascular death, were retrospectively analyzed. Cox proportional hazards regression analysis was used to explore factors, including clinical characteristics, embolic causes on transesophageal echocardiography, and the Calcification in the Aortic Arch, Age, Multiple Infarction score (CAM), based on the degree of aortic arch calcification on chest radiograph (0-3 points), age (>=70 years; 1 point), and multiple infarctions on magnetic resonance imaging (multiple infarcts in 1, 2, or >=3 territories of large intracranial arteries, 1, 2, or 3 points) associated with recurrent vascular events. RESULTS: A total of 177 patients (age, 64.1+/-14.2 years; 127 men) were enrolled. Thirty-one patients had recurrent vascular events (follow-up, 3.5+/-2.7 years; annualized rate, 5.0% per person-year). Among embolic causes on transesophageal echocardiography, incidence of recurrent vascular events was high in patients with large aortic arch plaques (7.5% per person-year). Diabetes mellitus (hazard ratio, 2.56; 95% confidence interval, 1.23-5.32; P=0.012) and CAM score grade (hazard ratio, 2.29; 95% confidence interval, 1.11-4.72; P=0.026) predicted recurrent vascular events. CONCLUSIONS: History of diabetes mellitus and the CAM score could be novel risk factors for recurrent vascular events in embolic stroke of undetermined source. PMID- 27703087 TI - Cerebral Small Vessel Disease Burden Is Increased in Systemic Lupus Erythematosus. AB - BACKGROUND AND PURPOSE: Systemic lupus erythematosus (SLE) increases stroke risk, but the mechanism is uncertain. This study aimed to determine the association between SLE and features on neuroimaging of cerebral small vessel disease (SVD), a risk factor for stroke. METHODS: Consecutive patients attending a clinic for SLE were recruited. All patients underwent brain magnetic resonance imaging; had blood samples taken for markers of inflammation, endothelial dysfunction, cholesterol, and autoantibodies; and underwent cognitive and psychiatric testing. The data were compared with sex- and age-matched healthy controls and patients with minor stroke. Features of SVD were measured, a total SVD score calculated, and associations sought with vascular risk factors, cognition, SLE activity, and disease duration. RESULTS: Fifty-one SLE patients (age: 48.8 years; SD: 14.3 years) had a greater total SVD score compared with healthy controls (1 versus 0; P<0.0001) and stroke patients (1 versus 0; P=0.02). There were higher perivascular spaces and deep white matter hyperintensity scores and more superficial brain atrophy in SLE patients versus healthy controls. Despite fewer vascular risk factors than similarly aged stroke patients, SLE patients had similar or more of some SVD features. The total SVD score was not associated with SLE activity, cognition, disease duration, or any blood measure. CONCLUSIONS: In this data set, SLE patients had a high burden of SVD features on magnetic resonance imaging, particularly perivascular spaces. A larger longitudinal study is warranted to determine the causes of SVD features in SLE and clinical implications. PMID- 27703088 TI - Rheumatic Mitral Valve Disease Is Associated With Worse Outcomes in Stroke: A Thailand National Database Study. AB - BACKGROUND AND PURPOSE: Rheumatic valvular heart disease is associated with the increased risk of cerebrovascular events, although there are limited data on the prognosis of patients with rheumatic mitral valve disease (RMVD) after stroke. METHODS: We examined the association between RMVD and both serious and common cardiovascular and noncardiovascular (respiratory and infective) complications in a cohort of hospitalized stroke patients based in Thailand. Factors associated with in-hospital mortality were also explored. Data were obtained from a National Insurance Database. All hospitalized strokes between October 1, 2004, and January 31, 2013, were included in the current study. Characteristics and outcomes were compared for RMVD and non-RMVD patients. Logistic regression, propensity score matching, and multivariate models were used to assess study outcomes. RESULTS: In total, 594 681 patients (mean [SD] age=64 [14.5] years) with a diagnosis of stroke (ischemic=306 154; hemorrhagic=195 392; undetermined=93 135) were included in this study, of whom 5461 had RMVD. Results from primary analyses showed that after ischemic stroke, and controlling for potential confounding covariates, RMVD was associated (P<0.001) with increased odds for cardiac arrest (odds ratio [95% confidence interval]=2.13 [1.68-2.70]), shock (2.13 [1.64-2.77]), arrhythmias (1.70 [1.21-2.39]), respiratory failure (2.09 [1.87-2.33]), pneumonia (2.00 [1.81 2.20]), and sepsis (1.39 [1.19-1.63]). In hemorrhagic stroke patients, RMVD was associated with increased odds (fully adjusted model) for respiratory failure (1.26 [1.01-1.57]), and in patients with undetermined stroke, RMVD was associated with increased odds (fully adjusted analyses) for shock (3.00 [1.46-6.14]), respiratory failure (2.70 [1.91-3.79]), and pneumonia (2.42 [1.88-3.11]). CONCLUSIONS: RMVD is associated with the development of cardiac arrest, shock, arrhythmias, respiratory failure, pneumonia, and sepsis after acute stroke. PMID- 27703089 TI - Development and Validation of an Automatic Segmentation Algorithm for Quantification of Intracerebral Hemorrhage. AB - BACKGROUND AND PURPOSE: ABC/2 is still widely accepted for volume estimations in spontaneous intracerebral hemorrhage (ICH) despite known limitations, which potentially accounts for controversial outcome-study results. The aim of this study was to establish and validate an automatic segmentation algorithm, allowing for quick and accurate quantification of ICH. METHODS: A segmentation algorithm implementing first- and second-order statistics, texture, and threshold features was trained on manual segmentations with a random-forest methodology. Quantitative data of the algorithm, manual segmentations, and ABC/2 were evaluated for agreement in a study sample (n=28) and validated in an independent sample not used for algorithm training (n=30). RESULTS: ABC/2 volumes were significantly larger compared with either manual or algorithm values, whereas no significant differences were found between the latter (P<0.0001; Friedman+Dunn's multiple comparison). Algorithm agreement with the manual reference was strong (concordance correlation coefficient 0.95 [lower 95% confidence interval 0.91]) and superior to ABC/2 (concordance correlation coefficient 0.77 [95% confidence interval 0.64]). Validation confirmed agreement in an independent sample (algorithm concordance correlation coefficient 0.99 [95% confidence interval 0.98], ABC/2 concordance correlation coefficient 0.82 [95% confidence interval 0.72]). The algorithm was closer to respective manual segmentations than ABC/2 in 52/58 cases (89.7%). CONCLUSIONS: An automatic segmentation algorithm for volumetric analysis of spontaneous ICH was developed and validated in this study. Algorithm measurements showed strong agreement with manual segmentations, whereas ABC/2 exhibited its limitations, yielding inaccurate overestimations of ICH volume. The refined, yet time-efficient, quantification of ICH by the algorithm may facilitate evaluation of clot volume as an outcome predictor and trigger for surgical interventions in the clinical setting.

PMID- 27703092 TI - Survival Outcomes for Combined Modality Therapy for Sinonasal Undifferentiated Carcinoma. AB - Objective Sinonasal undifferentiated carcinoma is a rare and aggressive malignancy of the nasal cavity and paranasal sinuses. Multi-institutional studies examining outcomes of combined modality treatment versus other treatment modalities have not been performed. The objective of our study was to present outcomes for multimodality therapy through use of the National Cancer Database. Study Design Retrospective cohort study. Setting National Cancer Database. Methods A total of 435 cases of SNUC diagnosed between 2004 and 2012 were identified. Kaplan-Meier analyses were performed to find 5-year cumulative survival rates. Multivariate Cox regression evaluated overall survival based on treatment when adjusting for other prognostic factors (age, primary site, sex, race, comorbidity, insurance, and TNM stage). Within the surgery + chemoradiotherapy group, survival analysis was also performed to compare outcomes for induction and adjuvant chemotherapy. Results The cumulative 5-year survival rate was 41.5%, and 36.1% of patients received surgery with chemoradiotherapy. In multivariate analysis, surgery + chemoradiotherapy was associated with significantly improved overall survival versus surgery + radiotherapy and radiotherapy but not significantly different from chemoradiotherapy. Within the surgery + chemoradiotherapy group, induction and adjuvant chemotherapy groups did not have associated differences in survival. Conclusion Combined modality therapy (chemoradiotherapy or surgery + chemoradiotherapy) is associated with improved survival outcomes versus other treatment modalities in patients with sinonasal undifferentiated carcinoma. PMID- 27703093 TI - Prevalence and Surgical Implications of Dural Enhancement at the Porus Acusticus in Vestibular Schwannomas. AB - OBJECTIVE: Demonstrate the association of radiographic dural enhancement with increased tumor adherence at the porus acusticus, which may influence completeness of resection and facial nerve outcome. STUDY DESIGN: Case series with chart review. SETTING: Academic referral center. SUBJECTS AND METHODS: A total of 205 consecutive patients with histopathologically confirmed vestibular schwannoma (VS) were evaluated. Patients with tumors exhibiting dural enhancement on postgadolinium T1-weighted magnetic resonance imaging were identified and compared with matched controls. Completeness of resection, intraoperative details, and facial nerve outcomes were analyzed. RESULTS: Excluding strictly intracanalicular tumors (n = 32, 16%) and those with NF2 (n = 10, 4.9%), the presence of dural enhancement was radiographically confirmed in 16 (9.8%) cases. Paired analysis did not reveal significant baseline differences between cases and controls. Subtotal resection was performed in 5 (31%) of the 16 patients with tumors exhibiting dural enhancement, in contrast to 1 (3%) of the matched controls (P = .01). Four (25%) demonstrated increased tumor adherence at the porus acusticus intraoperatively, compared with 1 control (3%, P = .04). Long term facial nerve function was similar between cases and controls (81% vs 84% House-Brackmann I-II function, P = 1.00). CONCLUSION: Dural enhancement is present in approximately 10% of extracanalicular VS. Dural enhancement at the porus acusticus may represent hypervascularity, dural reaction, or infiltration, and portends increased tumor adherence and greater likelihood of subtotal resection to preserve facial nerve function. To our knowledge, this is the first series that reports the prevalence of this phenomenon in VS and the potential surgical implications. Recognition preoperatively may be valuable toward patient counseling. PMID- 27703094 TI - Racial and Ethnic Disparities in Nasopharyngeal Cancer Survival in the United States. AB - Objective To determine whether patient race and ethnicity affect nasopharyngeal cancer survival. Study Design Retrospective database analysis. Setting National Cancer Institute's SEER database (Surveillance, Epidemiology, and End Results), 1988-2010. Subjects and Methods Nasopharyngeal carcinoma cases were extracted according to site codes and histology recode-broad groupings. The cohort of 5427 patients was used to calculate disease-specific survival in regard to race and ethnicity. Extracted data were further analyzed through direct comparisons and multivariable Cox regression models controlling for patient, tumor, and treatment characteristics. Results Unadjusted survival curves for all nasopharyngeal carcinomas considered together showed a statistically significant better disease specific survival for the African American race ( P = .02) and Asian ethnicity ( P = .01) relative to Caucasian patients. The survival advantage for both these groups was eliminated after controlling for the age and sex of the patients. Conclusion African American and Asian patients with nasopharyngeal cancer have better disease-specific survival as compared with Caucasian patients, while Hispanic ethnicity has no effect relative to Caucasians. This disparity is accounted for by diagnosis at an older age in Caucasian patients but remains poorly explained in regard to Hispanic patients. PMID- 27703095 TI - Screening for the metabolic syndrome in subjects with migraine. AB - Background Metabolic syndrome (MetS) and migraine are known to be associated. This study assessed the risk of MetS and its clinical characteristics in migraine with aura (MA) and without aura (MO) based on a large-scale cross-sectional survey. Methods The study material consisted of 751 participants in the Nutrition, Environment and CardioVascular Health (NESCaV) survey. Diagnosis of migraine was based on the ef-ID migraine questionnaire and MetS was defined according to the Revised-Adult Treatment Panel III criteria. Sociodemographic and risk factors were also recorded. Weighted logistic regression was used to assess the risk of MetS. Results After adjusting for stratification (gender, age, district) and other factors (smoking status, sedentary lifestyle, family history of stroke, myocardial infarction and hypertension), MA subjects were at higher risk of MetS (OR 3.45; 95% CI: 1.63-7.29) while MO individuals were not, when compared to non-migraineurs. When considering MetS components, MA was positively associated with low HDL-cholesterol (OR 2.26; 95% CI: 1.08-4.74), hyperglycemia (OR 2.77; 95% CI: 1.30-5.88) and abdominal obesity (OR 2.03; 95% CI: 1.07-3.86). Conclusion Migraineurs with aura are at higher risk of MetS, suggesting that these subjects, already more exposed to stroke, may benefit from a systematic screening for the metabolic syndrome. PMID- 27703096 TI - Wuling Capsule for Major Depressive Disorder: A Meta-analysis of Randomised Controlled Trials. AB - INTRODUCTION: In China, Wuling capsule, a traditional Chinese medicine consisting of Wuling mycelia of Xylaria nigripes (Kl.) Sacc (a rare type of fungus), is used to treat major depressive disorders. A meta-analysis of randomised controlled trials was performed to compare the efficacy and safety of Wuling capsule alone with Wuling capsule-antidepressant combination in the treatment of major depressive disorders. METHODS: Two assessors independently selected studies, extracted data, and conducted quality assessment and data synthesis. Standard mean difference, risk ratio (RR) +/- 95% confidence interval (CI), the number needed to treat, and the number needed to harm were analysed. RESULTS: A total of 12 randomised controlled trials (880 patients; mean age +/- standard deviation, 39.7 +/- 12.5 years; male patients, 41%) were identified, including 4 trials with Wuling capsule alone (n = 340) and 8 with Wuling capsule-antidepressant (sertraline, mianserin, mirtazapine, and paroxetine) combination (n = 540). The mean length of trial was 5.7 +/- 1.3 weeks. Meta-analysis of symptomatic improvement at last-observation endpoint and study-defined response and remission revealed no significant differences between the Wuling capsule alone and antidepressant monotherapy. The Wuling capsule-antidepressant cotreatment was superior to antidepressant monotherapy in symptomatic improvement at last observation endpoint (standard mean difference: -0.46, p = 0.001) as well as study-defined response (68.4% vs. 56.0%, RR = 1.23; p = 0.03) and remission (46.5% vs. 34.5%, RR = 1.35; p = 0.05). Wuling capsule was associated with fewer adverse drug reactions than antidepressant monotherapy. CONCLUSIONS: Adjunctive Wuling capsule may augment the effects of antidepressants and may be associated with fewer adverse drug reactions. More large-scale and rigorously designed randomised controlled trials with large sample size are warranted to clarify the effectiveness of Wuling capsule for major depressive disorders. PMID- 27703097 TI - Socio-demographic and Clinical Characteristics of Patients who Attempt Suicide: A Hospital-based Study from Eastern India. AB - INTRODUCTION: Suicide has become an important public health concern with a high number of deaths and increasing number of attempted suicides every year. There are multiple factors that underlie a suicide attempt. Although mental illness and severe stress have long been known to be associated with suicide, socio demographic and clinical characteristics of those attempting suicide can also provide indications of suicidal intent. The present study aimed to explore the socio-demographic and clinical characteristics of patients in Kolkata, India who attempted suicide. METHODS: Consecutive patients (n = 100) with failed suicide attempt who were referred to the psychiatry department of 2 multispecialty hospitals in Kolkata were included in the study. Their socio-demographic details and clinical characteristics were recorded. Suicidal intent and depressive symptoms were assessed and psychosocial risk factors were identified following detailed clinical interview. RESULTS: Suicide attempt was more frequent among younger female patients. Reaction to stress was the most common risk factor. The majority of attempts were impulsive in nature rather than planned. CONCLUSION: Young adults under stress are more vulnerable. Early identification of such individuals and psychosocial support to prevent suicidal ideation is vital. PMID- 27703098 TI - Cognitive Dysfunction and Associated Behaviour Problems in Postpartum Women: A Study from North India. AB - OBJECTIVES: During and after childbirth women undergo tremendous psychological and biological changes. These biological changes, along with the stress of assuming the new role of mother, make postpartum women vulnerable to various psychiatric disorders including cognitive dysfunction, depression, and anxiety. Such problems are under-reported as they are difficult to identify, especially by caregivers who are more focused on the newborn. The present study aimed to evaluate the prevalence of behaviour problems and cognitive dysfunction during the postpartum period. METHODS: A cross-sectional study was carried out at the Department of Obstetrics and Gynaecology, Jawahar Lal Nehru Medical College, Ajmer, India. The study sample included 200 consecutive women who came for their first follow-up after childbirth, and 100 healthy and non-pregnant women who served as controls. Cognitive function was assessed using the Standard Mini Mental State Examination Scale (SMMSE), Brief Cognitive Rating Scale (BCRS), and Trail Making Test Part B (TMT-B). 21-Item Depression Anxiety and Stress Scale was administered to assess depressive and anxiety symptoms. RESULTS: Postpartum women scored poorly on SMMSE, BCRS, and TMT-B compared with non-pregnant women (p < 0.001), whereas subscores of depression, anxiety, and stress were significantly higher (p < 0.001). CONCLUSIONS: Women had significantly more cognitive deficits during the postpartum period than their non-pregnant counterparts. The former also had a higher prevalence of depression, anxiety, and stress. PMID- 27703099 TI - Antiepileptic-induced Psychosis as a Possible Predictor of Post-temporal Lobectomy Alternative Psychosis. AB - We present a patient with topiramate-induced psychosis who developed alternative psychosis following temporal lobectomy. The number of surgical candidates for temporal lobectomy is increasing as is the frequency of psychiatric co morbidities. Preoperative planning should take account of these psychiatric co morbidities. In particular, precautions should be taken when antiepileptic drug induced psychosis occurs, as this could predict the occurrence of alternative psychosis following lobectomy.

AB - Midbrain dopamine neurons are activated by reward and sensory cue that predicts reward. Their responses resemble reward prediction error that indicates the discrepancy between obtained and expected reward values, which has been thought to play an important role as a teaching signal in reinforcement learning. Indeed, pharmacological blockade of dopamine transmission interferes with reinforcement learning. Recent studies reported, however, that not all dopamine neurons transmit the reward-related signal. They found that a subset of dopamine neurons transmits signals related to non-rewarding, salient experiences such as aversive stimulations and cognitively demanding events. How these signals contribute to animal behavior is not yet well understood. This article reviews recent findings on dopamine signals related to rewarding and non-rewarding experiences, and discusses their contributions to reinforcement learning. PMID- 27703102 TI - [Drug Dependence and Toxicity of Law-Evading Drugs: Their Mechanisms Explored from Basic Research]. AB - The number of law-evading chemical substances that pose serious health risks to humans is increasing worldwide, including Japan and the Western world, and their abuse is becoming a serious social problem. Analysis of the chemical substances in these herbal products revealed the presence of synthetic cannabinoids. This review summarizes the pharmacological actions and dangers of chemical substances contained in law-evading herbal products by focusing on synthetic cannabinoids as a group of chemical substances contained in these products. We established a psychic-dependence liability and cytotoxicity screening system for synthetic cannabinoids by using animals and cell cultures. In a place-conditioning study, the synthetic cannabinoids produced a significant conditioned-place preference. The rewarding effects of synthetic cannabinoids were completely suppressed by a cannabinoid CB1 receptor antagonist. Administration of synthetic cannabinoids to primary striatal culture caused cell death in a dose-dependent manner. Our findings show that the CB1 receptor might be involved in the expression of synthetic cannabinoid-induced rewarding effect. These behavioral data indicate that synthetic cannabinoids have a psychic-dependence liability. Furthermore, our data from primary striatal culture indicate that synthetic cannabinoids have strong neurotoxicity. These behavioral and neurochemical data indicate that synthetic cannabinoids might have strong adverse effects and a psychic-dependence liability. PMID- 27703103 TI - [The Concept and Treatment of Internet Addiction]. AB - The Internet now plays a very important role in our lives. However, for some people, Internet use can lead to a state that appears to meet the DSM definition for a mental disorder. In this review, we briefly discuss definition, symptoms, risk factors, prevalence, comorbidities, and personality traits of people who are susceptible to becoming addicts. In the second section of the article, various types of Internet addiction are discussed, focusing mainly on Internet Gaming Disorder and social networking survices (SNS) addiction. Regarding Internet Gaming Disorder, we discuss various types of the newly emerged Massive Multiplayer Online Games (MMO), as well as theories about why people become addicted to them. We do the same for the SNS Addiction for sites like Facebook and LINE; again, different types, as well as theories about why some people become addicts to such sites are discussed. Finally, preventive measures are introduced, focusing on a number of commonly used treatment methods, perticulary cognitive behavioral therapy and family therapy. PMID- 27703104 TI - [Ethical, Legal, and Social Issues (ELSI) in Gambling Disorder and Its Treatment]. AB - Recently, the Ministry of Health, Labor and Welfare estimated the prevalence rate of gambling disorder to be 4.8 percent of the population. This rate is outstandingly higher than other countries with prevalence rates between 0.25 and 2.0 percent. It is also estimated that no fewer than 5 million Japanese suffer from the disease. In the last two years, 100 new patients visited the author's clinic. On an average, they started gambling at the age of 19.7 years, and incurring debt at the age of 25.8 years. They first visited the clinic at an average age of 38.2 years, and the average amount they had spent on gambling up to that point was 13 million yen. Twenty percent of them had taken some legal measures to reduce their burden from debts before seeking treatment. Sixty percent of pathological gamblers exclusively played pachinko and slot machine games. Patients who did not play on such machines accounted for no less than 2 percent of cases. This is not surprising, considering the fact that Japan has nearly 4.6 million pachinko and slot machines, which account for two thirds of the total electric gaming machines in the world. Japanese legislation does not regard pachinko and slot machines as gambling, but merely as gaming. Therefore, pachinko companies have no restrictions as such to promote their market. They can advertise freely in newspapers and TV commercials. Pachinko halls are filled with lighting, sounds, and visual effects to stimulate and excite gamblers. The harmful effects of gambling disorder include depression, loss of employment and friends, marital discord, fraud, embezzlement, theft in the family, and theft from non-family members. The most helpful therapy involves attending self-help group sessions at least once a week. One of the best-known self-help groups is Gamblers Anonymous (GA); there are 162 GA groups in Japan. The author believes there should be one GA group for every city across the nation. Unfortunately, psychiatrists, who should be taking the lead in providing diagnosis and treatment, are showing little interest in gambling problems. Unless all psychiatrists develop the ability to deal with the disease effectively, there is little hope for patients and families to see a light at the end of the tunnel. It is also time for the administration to implement necessary measures instead of averting its eyes from the harsh reality and promoting publicly managed gambling. Considering the miserable situation, the administration should not lift its ban on the casino industry. PMID- 27703105 TI - [The Concept and Treatment of Kleptomania]. AB - Research on kleptomania has lagged behind that of other mental disorders, and very few clinicians specialize in treating such patients. Futhermore, the descriptive outline of kleptomania in the DSM-5 is vague. In 2008, we started a registration system for patients suffering from habitual theft, which has recorded 1430 cases since its inauguration. In this report, we explain the concept of kleptomania and describe our clinical experience in the treatment of patients suffering from this mental disorder. The most frequent complication of kleptomania was found to be eating disorder (especially bulimia). Although many factors contribute to the close relationship between these two mental disorders, the theory of "saving money on food expenses" as the motive for thefts committed by eating disorder patients, oversimplifies a complicated matter, and is inadequate as an explanation of the mechanism of this relationship. Medical treatment for kleptomania presently comprises counseling (individual psychotherapy), cognitive behavioral therapy, family therapy, group psychotherapy, psychodrama, and self-help groups, among others. In our addiction treatment approach, we have developed and implemented a program wherein recovered (recovering) patients share their personal experiences with newcomers and beginners, as well as their family members. We strongly encourage patients with kleptomania to participate in self-help groups. PMID- 27703106 TI - [Recovery from Sexual Addiction].

PMID- 27703107 TI - [The Prion-like Mechanism in Neurodegenerative Diseases-Current Studies and Future Prospects]. AB - Intracellular abnormal protein deposits, such as tau, alpha-synuclein and TDP-43, are the hallmark of many neurodegenerative diseases, and the distributions of these pathological proteins are closely correlated with disease symptoms and progression. A growing body of evidence strongly suggests that these abnormal proteins have prion-like properties: they convert normal proteins into abnormal forms, self-propagate through neuronal networks, and then spread in the brain. This prion-like propagation of abnormal proteins may account for the diversity, selective degeneration and disease progression seen in neurodegenerative diseases, although the molecular mechanism remains uncertain the molecular details of this mechanism. This review describes recent studies on prion-like properties of abnormal proteins in vitro, in cells and in animal experimental models. PMID- 27703108 TI - [The Function of REM Sleep: Implications from Transgenic Mouse Models]. AB - Our sleep is composed of rapid eye movement (REM) sleep and non-REM (NREM) sleep. REM sleep is the major source of dreams, whereas synchronous cortical oscillations, called slow waves, are observed during NREM sleep. Both stages are unique to certain vertebrate species, and therefore, REM and NREM sleep are thought to be involved in higher-order brain functions. While several studies have revealed the importance of NREM sleep in growth hormone secretion, memory consolidation and brain metabolite clearance, the functions of REM sleep are currently almost totally unknown. REM sleep functions cannot be easily indicated from classical REM sleep deprivation experiments, where animals are forced to wake up whenever they enter REM sleep, because such experiments produce extreme stress due to the stimuli and because REM sleep is under strong homeostatic regulation. To overcome these issues, we developed a novel transgenic mouse model in which REM sleep can be manipulated. Using these mice, we found that REM sleep enhances slow wave activity during the subsequent NREM sleep. Slow wave activity is known to contribute to memory consolidation and synaptic plasticity. Thus, REM sleep might be involved in higher-order brain functions through its role in enhancing slow wave activity. PMID- 27703109 TI - [Clinical Implications and Appropriate Use of Amyloid Imaging with florbetapir (18F) in Diagnosis of Patients with Alzheimer Disease]. AB - florbetapir (18F) is a radiolabeled compound that can be used to visualize amyloid-beta (Abeta) plaques in the brains of patients with cognitive dysfunction, who are suspected of having Alzheimer disease (AD). Knowing the status of Abeta accumulation in the brain is beneficial to selecting therapeutic strategies or to planning of laboratory examinations, hence amyloid PET imaging is expected to be utilized more often in a clinical setting. Based on the results of a clinical study of florbetapir (18F), this review discusses the usefulness and clinical significance of amyloid PET imaging, and its appropriate use in Japan.

PMID- 27703110 TI - [Isolated Severe Dysphagia Associated with Medial Medullary Infarction: A Case Report and Review of the Literature]. AB - A 59-year-old man developed a sudden onset of vertigo and nausea, and after a few hours, he could not swallow at all. On admission, neurological examination revealed severe dysphagia associated with other transient and mild neurological deficits, including left facial paresis, and hypesthesia in the right side of his body. MRI with diffusion weighted imaging showed a hyperintense signal lesion at the left rostral medial region of the medulla, prompting the diagnosis of an acute medial medullary infarction. His facial paresis and hypesthesia disappeared within 2 weeks. Despite lacking motor paralysis in the tongue, soft palate, and pharyngeal muscle, the patient had severe and prolonged dysphagia. It is speculated that the lesion in this patient is located at the central pattern generator (CPG), which is thought to be the human swallowing center.

PMID- 27703114 TI - Sex and Gender Differences in Gastroesophageal Reflux Disease. AB - It is important to understand sex and gender-related differences in gastroesophageal reflux disease (GERD) because gender-related biologic factors might lead to better prevention and therapy. Non-erosive reflux disease (NERD) affects more women than men. GERD symptoms are more frequent in patients with NERD than in those with reflux esophagitis. However, men suffer pathologic diseases such as reflux esophagitis, Barrett's esophagus (BE), and esophageal adenocarcinoma (EAC) more frequently than women. The prevalence of reflux esophagitis is significantly increased with age in women, especially after their 50s. The mean age of EAC incidence in women is higher than in men, suggesting a role of estrogen in delaying the onset of BE and EAC. In a chronic rat reflux esophagitis model, nitric oxide was found to be an aggravating factor of esophageal injury in a male-predominant way. In addition, the expression of esophageal occludin, a tight junction protein that plays an important role in the esophageal defense mechanism, was up-regulated in women. This explains the male predominance of reflux esophagitis and delayed incidence of BE or EAC in women. Moreover, the symptoms such as heartburn, regurgitation, and extra-esophageal symptoms have been more frequently reported by women than by men, suggesting that sex and gender play a role in symptom perception. Differential sensitivity with augmented symptoms in women might have diagnostic and therapeutic influence. Furthermore, recent studies have suggested that hormone replacement therapy has a protective effect against esophageal cancer. However, an anti-inflammatory role of estrogen remains compelling, which means further study is necessary in this area. PMID- 27703116 TI - A new high-pressure strontium germanate, SrGe2O5. AB - The Sr-Ge-O system has an earth-scientific importance as a potentially good low pressure analog of the Ca-Si-O system, one of the major components in the constituent minerals of the Earth's crust and mantle. However, it is one of the germanate systems that has not yet been fully examined in the phase relations and structural properties. The recent findings that the SrGeO3 high-pressure perovskite phase is the first Ge-based transparent electronic conductor make the Sr-Ge-O system interesting in the field of materials science. In the present study, we have revealed the existence of a new high-pressure strontium germanate, SrGe2O5. Single crystals of this compound crystallized as a co-existent phase with SrGeO3 perovskite single crystals in the sample recovered in the compression experiment of SrGeO3 pseudowollastonite conducted at 6 GPa and 1223 K. The crystal structure consists of germanium-oxygen framework layers stacked along [001], with Sr atoms located at the 12-coordinated cuboctahedral site; the layers are formed by the corner linkages between GeO6 octahedra and between GeO6 octahedra and GeO4 tetrahedra. The present SrGe2O5 is thus isostructural with the high-pressure phases of SrSi2O5 and BaGe2O5. Comparison of these three compounds leads to the conclusion that the structural responses of the GeO6 and GeO4 polyhedra to cation substitution at the Sr site are much less than that of the SrO12 cuboctahedron to cation substitution at the Ge sites. Such a difference in the structural response is closely related to the bonding nature.

AB - A fixed hydrogen-bonding motif with a high probability of occurring when appropriate functional groups are involved is described as a 'supramolecular hydrogen-bonding synthon'. The identification of these synthons may enable the prediction of accurate crystal structures. The rare chiral hydrogen-bonding motif R53(10) was observed previously in a cocrystal of 2,4,6-trichlorophenol, 2,4 dichlorophenol and dicyclohexylamine. In the title solvated salt, 2C4H12N+.C6H3Cl2O-.(C6H3Cl2O-.C6H4Cl2O).2C4H8O, five components, namely two tert butylammonium cations, one 2,4-dichlorophenol molecule, one 2,4-dichlorophenolate anion and one 2,6-dichlorophenolate anion, are bound by N-H...O and O-H...O hydrogen bonds to form a hydrogen-bonded ring, with the graph-set motif R53(10), which is further associated with two pendant tetrahydrofuran molecules by N-H...O hydrogen bonds. The hydrogen-bonded ring has internal symmetry, with a twofold axis running through the centre of the 2,6-dichlorophenolate anion, and is isostructural with a previous and related structure formed from 2,4 dichlorophenol, dicyclohexylamine and 2,4,6-trichlorophenol. In the title crystal, helical columns are built by the alignment and twisting of the chiral hydrogen-bonded rings, along and across the c axis, and successive pairs of rings are associated with each other through C-H...pi interactions. Neighbouring helical columns are inversely related and, therefore, no chirality is sustained, in contrast to the previous case. PMID- 27703118 TI - Two new two-dimensional coordination polymers based on isophthalate and a flexible N-donor ligand containing benzimidazole and pyridine rings: synthesis, crystal structures and a solid-state UV-Vis study. AB - In coordination chemistry and crystal engineering, many factors influence the construction of coordination polymers and the final frameworks depend greatly on the organic ligands used. N-Donor ligands with diverse coordination modes and conformations have been employed to assemble metal-organic frameworks. Carboxylic acid ligands can deprotonate completely or partially when bonding to metal ions and can also act as donors or acceptors of hydrogen bonds and are thus good candidates for the construction of supramolecular architectures. Two new transition metal complexes, namely poly[diaqua(MU4-1,4-bis{[1-(pyridin-3 ylmethyl)-1H-benz[d]imidazol-2-yl]methoxy}benzene)bis(MU2 isophthalato)dicobalt(II)], [Co(C8H4O4)(C34H28N6O2)0.5(H2O)]n, (1), and poly[diaqua(MU4-1,4-bis{[1-(pyridin-3-ylmethyl)-1H-benz[d]imidazol-2 yl]methoxy}benzene)bis(MU2-isophthalato)dicadmium(II)], [Cd(C8H4O4)(C34H28N6O2)0.5(H2O)]n, have been constructed using a symmetric N donor ligand and a carboxylate ligand under hydrothermal conditions. X-ray crystallographic studies reveal that complexes (1) and (2) are isostructural, both of them exhibiting three-dimensional supramolecular architectures built by hydrogen bonds in which the coordinated water molecules serve as donors, while the O atoms of the carboxylate groups act as acceptors. Furthermore, (1) and (2) have been characterized by elemental, IR spectroscopic, powder X-ray diffraction (PXRD) and thermogravimetric analyses. The UV-Vis absorption spectrum of complex (1) has also been investigated. PMID- 27703119 TI - The tropolone-isobutylamine complex: a hydrogen-bonded troponoid without dominant pi-pi interactions. AB - Tropolone long has served as a model system for unraveling the ubiquitous phenomena of proton transfer and hydrogen bonding. This molecule, which juxtaposes ketonic, hydroxylic, and aromatic functionalities in a framework of minimal complexity, also has provided a versatile platform for investigating the synergism among competing intermolecular forces, including those generated by hydrogen bonding and aryl coupling. Small members of the troponoid family typically produce crystals that are stabilized strongly by pervasive pi-pi, C H...pi, or ion-pi interactions. The organic salt (TrOH.iBA) formed by a facile proton-transfer reaction between tropolone (TrOH) and isobutylamine (iBA), namely isobutylammonium 7-oxocyclohepta-1,3,5-trien-1-olate, C4H12N+.C7H5O2-, has been investigated by X-ray crystallography, with complementary quantum-chemical and statistical-database analyses serving to elucidate the nature of attendant intermolecular interactions and their synergistic effects upon lattice-packing phenomena. The crystal structure deduced from low-temperature diffraction measurements displays extensive hydrogen-bonding networks, yet shows little evidence of the aryl forces (viz. pi-pi, C-H...pi, and ion-pi interactions) that typically dominate this class of compounds. Density functional calculations performed with and without the imposition of periodic boundary conditions (the latter entailing isolated subunits) documented the specificity and directionality of noncovalent interactions occurring between the proton-donating and proton accepting sites of TrOH and iBA, as well as the absence of aromatic coupling mediated by the seven-membered ring of TrOH. A statistical comparison of the structural parameters extracted for key hydrogen-bond linkages to those reported for 44 previously known crystals that support similar binding motifs revealed TrOH.iBA to possess the shortest donor-acceptor distances of any troponoid-based complex, combined with unambiguous signatures of enhanced proton-delocalization processes that putatively stabilize the corresponding crystalline lattice and facilitate its surprisingly rapid formation under ambient conditions.

AB - The study of ternary systems is interesting because it introduces the concept of molecular preference/competition into the system where one molecule may be displaced because the association between the other two is significantly stronger. Current definitions of a tertiary system indicate that solvent molecules are excluded from the molecule count of the system and some of the latest definitions state that any molecule that is not a solid in the parent form at room temperature should also be excluded from the molecule count. In the structure of the quinoline adduct hydrate of tryptaminium 3,5-dinitrobenzoate, 3C10H13N2+.3C7H3N2O6-.2C9H7N.2H2O, the asymmetric unit comprises multiple cation and anion species which are conformationally similar among each type set. In the crystal, a one-dimensional hydrogen-bonded supramolecular structure is generated through extensive intra- and inter-unit aminium N-H...O and N-H...N, and water O H...O hydrogen bonds. Within the central-core hydrogen-bonding associations, conjoined cyclic R44(10), R53(10) and R44(12) motifs are generated. The unit is expanded into a one-dimensional column-like polymer extending along [010]. Present also in the crystal packing of the structure are a total of 19 pi-pi interactions involving both cation, anion and quinoline species [ring-centroid separation range = 3.395 (3)-3.797 (3) A], as well as a number of weak C-H...O hydrogen-bonding associations. The presence of the two water molecules in the crystal structure is considered to be the principal causative factor in the low symmetry of the asymmetric unit. PMID- 27703121 TI - The antitumour drug 7-ethyl-10-hydroxycamptothecin monohydrate and its solid state hydrolysis mechanism on heating. AB - 7-Ethyl-10-hydroxycamptothecin [systematic name: (4S)-4,11-diethyl-4,9-dihydroxy 1H-pyrano[3',4':6,7]indolizino[1,2-b]quinoline-3,14(4H,12H)-dione, SN-38] is an antitumour drug which exerts activity through the inhibition of topoisomerase I. The crystal structure of SN-38 as the monohydrate, C22H20N2O5.H2O, reveals that it is a monoclinic crystal, with one SN-38 molecule and one water molecule in the asymmetric unit. When the crystal is heated to 473 K, approximately 30% of SN-38 is hydrolyzed at its lactone ring, resulting in the formation of the inactive carboxylate form. The molecular arrangement around the water molecule and the lactone ring of SN-38 in the crystal structure suggests that SN-38 is hydrolyzed by the water molecule at (x, y, z) nucleophilically attacking the carbonyl C atom of the lactone ring at (x - 1, y, z - 1). Hydrogen bonding around the water molecules and the lactone ring appears to promote this hydrolysis reaction: two carbonyl O atoms, which are hydrogen bonded as hydrogen-bond acceptors to the water molecule at (x, y, z), might enhance the nucleophilicity of this water molecule, while the water molecule at (-x, y + 1/2, -z), which is hydrogen bonded as a hydrogen-bond donor to the carbonyl O atom at (x - 1, y, z - 1), might enhance the electrophilicity of the carbonyl C atom.

AB - Weak interactions between organic molecules are important in solid-state structures where the sum of the weaker interactions support the overall three dimensional crystal structure. The sp-C-H...N hydrogen-bonding interaction is strong enough to promote the deliberate cocrystallization of a series of diynes with a series of dipyridines. It is also possible that a similar series of cocrystals could be formed between molecules containing a terminal alkyne and molecules which contain carbonyl O atoms as the potential hydrogen-bond acceptor. I now report the crystal structure of two cocrystals that support this hypothesis. The 1:1 cocrystal of 1,4-diethynylbenzene with 1,3-diacetylbenzene, C10H6.C10H10O2, (1), and the 1:1 cocrystal of 1,4-diethynylbenzene with benzene 1,4-dicarbaldehyde, C10H6.C8H6O2, (2), are presented. In both cocrystals, a strong nonconventional ethynyl-carbonyl sp-C-H...O hydrogen bond is observed between the components. In cocrystal (1), the C-H...O hydrogen-bond angle is 171.8 (16) degrees and the H...O and C...O hydrogen-bond distances are 2.200 (19) and 3.139 (2) A, respectively. In cocrystal (2), the C-H...O hydrogen-bond angle is 172.5 (16) degrees and the H...O and C...O hydrogen-bond distances are 2.25 (2) and 3.203 (2) A, respectively.

AB - Acetic anhydride (ethanoic anhydride), (CH3CO)2O, is a widely used acetylation reagent in organic synthesis. The crystal and molecular structure, as determined by single-crystal X-ray analysis at 100 K, is reported for the first time. A crystal of the title compound (m.p. 200 K) suitable for X-ray diffraction was grown from the melt at low temperature. The title compound crystallizes in the orthorhombic space group Pbcn, with Z = 4. In the crystal, the molecule adopts an exact C2-symmetric conformation about a crystallographic twofold axis. The molecules are densely packed. Two of the methyl H atoms form short intermolecular contacts to a neighbouring carbonyl O atom, which can be viewed as weak hydrogen bonds.

AB - Crystallization experiments with the dinuclear chelate ring complex di-MU chlorido-bis[(eta2-2-allyl-4-methoxy-5-{[(propan-2-yloxy)carbonyl]methoxy}phenyl kappaC1)platinum(II)], [Pt2(C15H19O4)2Cl2], containing a derivative of the natural compound eugenol as ligand, have been performed. Using five different sets of crystallization conditions resulted in four different complexes which can be further used as starting compounds for the synthesis of Pt complexes with promising anticancer activities. In the case of vapour diffusion with the binary chloroform-diethyl ether or methylene chloride-diethyl ether systems, no change of the molecular structure was observed. Using evaporation from acetonitrile (at room temperature), dimethylformamide (DMF, at 313 K) or dimethyl sulfoxide (DMSO, at 313 K), however, resulted in the displacement of a chloride ligand by the solvent, giving, respectively, the mononuclear complexes (acetonitrile kappaN)(eta2-2-allyl-4-methoxy-5-{[(propan-2-yloxy)carbonyl]methoxy}phenyl kappaC1)chloridoplatinum(II) monohydrate, [Pt(C15H19O4)Cl(CH3CN)].H2O, (eta2-2 allyl-4-methoxy-5-{[(propan-2-yloxy)carbonyl]methoxy}phenyl kappaC1)chlorido(dimethylformamide-kappaO)platinum(II), [Pt(C15H19O4)Cl(C2H7NO)], and (eta2-2-allyl-4-methoxy-5-{[(propan-2-yloxy)carbonyl]methoxy}phenyl kappaC1)chlorido(dimethyl sulfoxide-kappaS)platinum(II), determined as the analogue {eta2-2-allyl-4-methoxy-5-[(ethoxycarbonyl)methoxy]phenyl kappaC1}chlorido(dimethyl sulfoxide-kappaS)platinum(II), [Pt(C14H17O4)Cl(C2H6OS)]. The crystal structures confirm that acetonitrile interacts with the PtII atom via its N atom, while for DMSO, the S atom is the coordinating atom. For the replacement, the longest of the two Pt-Cl bonds is cleaved, leading to a cis position of the solvent ligand with respect to the allyl group. The crystal packing of the complexes is characterized by dimer formation via C-H...O and C-H...pi interactions, but no pi-pi interactions are observed despite the presence of the aromatic ring. PMID- 27703126 TI - Treatment outcomes after adjuvant radiotherapy following surgery for patients with stage I endometrial cancer. AB - PURPOSE: The purpose of this study is to evaluate the treatment outcomes of adjuvant radiotherapy using vaginal brachytherapy (VB) with a lower dose per fraction and/or external beam radiotherapy (EBRT) following surgery for patients with stage I endometrial carcinoma. MATERIALS AND METHODS: The subjects were 43 patients with the International Federation of Gynecology and Obstetrics (FIGO) stage I endometrial cancer who underwent adjuvant radiotherapy following surgery between March 2000 and April 2014. Of these, 25 received postoperative VB alone, while 18 received postoperative EBRT to the whole pelvis; 3 of these were treated with EBRT plus VB. The median EBRT dose was 50.0 Gy (45.0-50.4 Gy) and the VB dose was 24 Gy in 6 fractions. Tumor dose was prescribed at a depth of 5 mm from the cylinder surface and delivered twice per week. RESULTS: The median follow-up period for all patients was 57 months (range, 9 to 188 months). Five-year disease free survival (DFS) and overall survival (OS) for all patients were 92.5% and 95.3%, respectively. Adjuvant radiotherapy was performed according to risk factors and stage IB, grade 3 and lymphovascular invasion were observed more frequently in the EBRT group. Five-year DFS for EBRT and VB alone were 88.1% and 96.0%, respectively (p = 0.42), and 5-year OS for EBRT and VB alone were 94.4% and 96%, respectively (p = 0.38). There was no locoregional recurrence in any patient. Two patients who received EBRT and 1 patient who received VB alone developed distant metastatic disease. Two patients who received EBRT had severe complications, one each of grade 3 gastrointestinal complication and pelvic bone insufficiency fracture. CONCLUSION: Adjuvant radiotherapy achieved high DFS and OS with acceptable toxicity in stage I endometrial cancer. VB (with a lower dose per fraction) may be a viable option for selected patients with early-stage endometrial cancer following surgery. PMID- 27703127 TI - Age-period-cohort analysis of hepatitis A incidence rates in Korea from 2002 to 2012. AB - OBJECTIVES: This study aimed to evaluate the epidemiology of hepatitis A in Korea from 2002 to 2012 using age-period-cohort analyses. METHODS: We used claims data from the Korean National Health Insurance Corporation for the entire population. Census data from 2010 were used as the standard population. The incidence of hepatitis A was assumed to have a Poisson distribution, and the models and effects were evaluated using the intrinsic estimator method, the likelihood ratio, and the Akaike information criterion. RESULTS: The incidence of hepatitis A gradually increased until 2007 (from 17.55 to 35.72 per 100,000 population) and peaked in 2009 (177.47 per 100,000 population). The highest incidence was observed among 27-29-year-old individuals when we omitted data from 2005 to 2007. From 2005 to 2007, the peak incidence was observed among 24-26-year-old individuals, followed by 27-29-year-olds. The best model fits were observed when the age-period-cohort variables were all considered at the same time for males, females, and the whole population. CONCLUSIONS: The incidence of hepatitis A exhibited significant age-period-cohort effects; its incidence peaked in 2009 and was especially high among Koreans 20-39 years of age. These epidemiological patterns may help predict when high incidence rates of hepatitis A may occur in developing countries during their socioeconomic development. PMID- 27703130 TI - Use of Lysozyme as a Feed Additive on In vitro Rumen Fermentation and Methane Emission. AB - This study was conducted to determine the effect of lysozyme addition on in vitro rumen fermentation and to identify the lysozyme inclusion rate for abating methane (CH4) production. An in vitro ruminal fermentation technique was done using a commercial concentrate to rice straw ratio of 8:2 as substrate. The following treatments were applied wherein lysozyme was added into 1 mg dry matter substrate at different levels of inclusion: Without lysozyme, 2,000, 4,000, and 8,000 U lysozyme. Results revealed that, lysozyme addition had a significant effect on pH after 24 h of incubation, with the highest pH (p<0.01) observed in 8,000 U lysozyme, followed by the 4,000 U, 2,000 U, and without lysozyme. The highest amounts of acetic acid, propionic acid (p<0.01) and total volatile fatty acid (TVFA) (p<0.05) were found in 8,000 U after 24 h of incubation. The CH4 concentration was the lowest in the 8,000 U and the highest in the without lysozyme addition after 24 h of incubation. There was no significant differences in general bacteria, methanogen, or protozoan DNA copy number. So far, addition of lysozyme increased the acetate, propionate, TVFA, and decreased CH4 concentration. These results suggest that lysozyme supplementation may improve in vitro rumen fermentation and reduce CH4 emission. PMID- 27703129 TI - Overview of Brucellosis in Nepal. AB - Brucellosis is an abortifacient zoonotic disease which remains prominent in third world countries like Nepal. Brucellosis possess a public health concern, the incidences of which in livestocks can present substantial economic and health burdens for herders and health professionals. In Nepal, several cases of bovine including human brucellosis have been reported. This paper aims to evaluate the current status of the disease, the mechanism of infection, pathogenesis, zoonotic potential, diagnostic advances, treatment regimens, and the preventive measures that can be adopted in managing human brucellosis in under-developed countries like Nepal. Extensive review of all the available literatures in Nepal. Secondary information from various legitimate sources. There is a higher prevalence of Brucellosis among livestock but relatively lower prevalence among humans in Nepal as reported by many scholars. Lack of awareness, unhealthy food habit, orthodox husbandry practices, lack of surveillance and immunization has been the major factors in maintaining a vicious cycle of the disease maintenance and propagation in human and animals. PMID- 27703131 TI - Effects of age on intestinal phosphate transport and biochemical values of broiler chickens. AB - OBJECTIVE: The objective of this experiment was to characterize the mRNA expression profile of type IIb sodium-inorganic phosphate cotransporter (NaPi IIb) and the biochemical values of serum alkaline phosphatase (AKP), calcium, inorganic phosphorus, tibial ash and minerals of broiler chickens with aging. METHODS: A total of 56 one-day-old Arbor Acres male broiler chickens were used. Broiler chickens were weighed and samples were collected weekly from day 1. RESULTS: The result showed that before the growth inflection point, ash, calcium, and phosphorus content in the tibia of broiler chickens increased with growth (before 3 weeks of age), although there were no significant differences in chicks at different ages in the later period of the experiment and weight gain rate was relatively slow at this stage (4 to 6 weeks). NaPi-IIb gene expression in the small intestine in the early growth stage was higher than that in the later growth stage. Expression of calbindin and the vitamin D receptor protein in the intestinal mucosa increased with age in the duodenum and jejunum. Serum AKP activity first increased and subsequently decreased after peaking at 1 week of age, but there was no significant difference after 3 weeks of age. CONCLUSION: These results show that compared with the early growth stage, the weight-gain rate of broiler chickens in the late growth stage gradually decreased with gradual tibia maturation, along with weaker positive transport of phosphorus in the intestine and reinforced re-absorption of phosphorus in the kidney, which might be the reason that phosphorus requirement in the late growth stage was decreased. PMID- 27703132 TI - Multiple-enzyme supplementation on digestive traits, carcass characteristics, blood lipid parameters and growth performance of broilers fed a wheat-based diet. AB - OBJECTIVE: A trial was conducted from 11 to 42 d post-hatch to investigate the effectiveness of the supplementation of a multiple-enzyme preparation (Natuzyme Plus) in a wheat-based diet on digesta viscosity, pH and microbial population, villus morphology, feed passage time, nutrient retention, carcass characteristics, blood lipid parameters and growth performance of broiler chickens. METHODS: Three hundreds 10-d-old male Ross 308 chicks were allocated to three diets with five replicates of 20 birds per replicate. Dietary treatments were i) a wheat-based diet (W), ii) W+Natuzyme Plus (WN; 500 mg/kg of the diet), and iii) a corn-based diet (C). RESULTS: Birds fed on the C diet had higher average daily gain (ADG, p<0.01), villus height (VH, p<0.01), total tract apparent retention (TTAR) of nitrogen (NT, p<0.01) and ether extract (EE, p<0.01), nitrogen-corrected apparent metabolizable energy (AMEn, p<0.05), relative weight (RW, % of body weight) of carcass (p<0.05), blood concentration of triglyceride (TG, on d 40 [p<0.01]), total cholesterol (TC, on d 22 [p<0.05]) and low density lipoprotein (LDL, on d 22 [p<0.01] and 40 [p<0.05]), and also lower feed conversion ratio (FCR, p<0.01), digesta viscosity (p<0.01), count of coliforms (p<0.01) and Escherichia coli (p<0.01) and epithelium thickness (ET, p<0.05) than those fed on the W diet. ADG, FCR, VH, ET, TTAR of NT and EE, RW of carcass, blood concentration of TG (on d 40), TC (on d 22) and LDL (on d 22 and 40) values of the WN diet did not show a significant (p>0.05) difference compared to those of the C diet. Compared to those of the W diet, the WN diet showed the higher count of Lactobacilli and lower count of coliforms (p<0.01) and digesta viscosity (p<0.01). CONCLUSION: In general, the results of this study showed that Natuzyme Plus supplementation in a wheat-based diet can be appropriate to achieve a comparable growth performance in broiler chickens to those given the C diet probably through improving digesta viscosity, VH, ET, TTAR of NT and EE, AMEn, count of Lactobacilli and coliforms. PMID- 27703133 TI - Silage preparation and fermentation quality of natural grasses treated with lactic acid bacteria and cellulase in meadow steppe and typical steppe. AB - OBJECTIVE: In order to improve fermentation quality of natural grasses, their silage preparation and fermentation quality in meadow steppe (MS) and typical steppe (TS) were studied. METHODS: The small-scale silages and round bale silages of mixed natural grasses in both steppes were prepared using the commercial lactic acid bacteria (LAB) inoculants Chikuso-1 (CH, Lactobacillus plantarum) and cellulase enzyme (AC, Acremonium cellulase) as additives. RESULTS: MS and TS contained 33 and 9 species of natural grasses, respectively. Stipa baicalensis in MS and Stipa grandi in TS were the dominant grasses with the highest dry matter (DM) yield. The crude protein (CP), neutral detergent fiber and water-soluble carbohydrate of the mixed natural grasses in both steppes were 8.02% to 9.03%, 66.75% to 69.47%, and 2.02% to 2.20% on a DM basis, respectively. All silages treated with LAB and cellulase were well preserved with lower pH, butyric acid and ammonia-N content, and higher lactic acid and CP content than those of control in four kinds of silages. Compared with CH- or AC-treated silages, the CH+ AC-treated silages had higher lactic acid content. CONCLUSION: The results confirmed that combination with LAB and cellulase may result in beneficial effects by improving the natural grass silage fermentation in both grasslands. PMID- 27703134 TI - Intracerebral and Intravenous Transplantation Represents a Favorable Approach for Application of Human Umbilical Cord Mesenchymal Stromal Cells in Intracerebral Hemorrhage Rats. AB - BACKGROUND Intracerebral hemorrhage (ICH) is one severe subtype of stroke, with a very complex pathology. Stem cell-based therapy holds promising potential in the treatment of neurological disorders. Human umbilical cord-derived mesenchymal stem cells (UC-MSCs) have a therapeutic effect in recovery from brain damage following ICH. The aim of this study was to identify an effective and convenient way of using UC-MSCs in the ICH rat model. MATERIAL AND METHODS CM-DiI-labeled human UC-MSCs were transplanted intracerebrally or intravenously into collagenase VII-induced ICH rat models. Neurological function was evaluated before ICH and at 0, 7, 14, 21, and 28 days after treatment. ICH rats were sacrificed to evaluate the injury volume. Neurogenesis and angiogenesis and vascular areas were investigated using microtubule-associated protein 2 (MAP2), glial fibrillary acidic protein (GFAP), and 4',6-diamidino-2-phenylindole (DAPI) immunohistochemistry at two weeks after transplantation. RESULTS The intracerebral and intravenous administration of UC-MSCs both resulted in significant improvement in neurological function and decrease in injury volume of ICH rats. Transplanted UC-MSCs were chemotactic in vivo and showed a predominant distribution around the ICH region. In addition, UC-MSCs could integrate into the cerebral vasculature in both groups. CONCLUSIONS Both intracerebral and intravenous administration of UC-MSCs could have a favorable effect on recovery of neurological function in ICH rats, although the fundamental mechanisms may be different between the two groups. Our data suggest that intravenous implantation of UC-MSCs could serve as a favorable approach for cell-based therapy in central nervous system (CNS) diseases according to clinical needs. PMID- 27703136 TI - Enhancing stability and efficiency of perovskite solar cells with crosslinkable silane-functionalized and doped fullerene. AB - The instability of hybrid perovskite materials due to water and moisture arises as one major challenge to be addressed before any practical application of the demonstrated high efficiency perovskite solar cells. Here we report a facile strategy that can simultaneously enhance the stability and efficiency of p-i-n planar heterojunction-structure perovskite devices. Crosslinkable silane molecules with hydrophobic functional groups are bonded onto fullerene to make the fullerene layer highly water-resistant. Methylammonium iodide is introduced in the fullerene layer for n-doping via anion-induced electron transfer, resulting in dramatically increased conductivity over 100-fold. With crosslinkable silane-functionalized and doped fullerene electron transport layer, the perovskite devices deliver an efficiency of 19.5% with a high fill factor of 80.6%. A crosslinked silane-modified fullerene layer also enhances the water and moisture stability of the non-sealed perovskite devices by retaining nearly 90% of their original efficiencies after 30 days' exposure in an ambient environment.

Typhi), the causative agent of typhoid fever, exhibits limited DNA sequence variation, which complicates efforts to rationally discriminate individual isolates. Here we utilize data from whole-genome sequences (WGS) of nearly 2,000 isolates sourced from over 60 countries to generate a robust genotyping scheme that is phylogenetically informative and compatible with a range of assays. These data show that, with the exception of the rapidly disseminating H58 subclade (now designated genotype 4.3.1), the global S. Typhi population is highly structured and includes dozens of subclades that display geographical restriction. The genotyping approach presented here can be used to interrogate local S. Typhi populations and help identify recent introductions of S. Typhi into new or previously endemic locations, providing information on their likely geographical source. This approach can be used to classify clinical isolates and provides a universal framework for further experimental investigations.

AB - Experimental band structure analyses of single-walled carbon nanotubes have not yet been reported, to the best of our knowledge, except for a limited number of reports using scanning tunnelling spectroscopy. Here we demonstrate the experimental determination of the excitonic band structures of single-chirality single-walled carbon nanotubes using their circular dichroism spectra. In this analysis, we use gel column chromatography combining overloading selective adsorption with stepwise elution to separate 12 different single-chirality enantiomers. Our samples show higher circular dichroism intensities than the highest values reported in previous works, indicating their high enantiomeric purity. Excitonic band structure analysis is performed by assigning all observed Eii and Eij optical transitions in the circular dichroism spectra. The results reproduce the asymmetric structures of the valence and conduction bands predicted by density functional theory. Finally, we demonstrate that an extended empirical formula can estimate Eij optical transition energies for any (n,m) species.

AB - The bacterial pathway for fatty acid biosynthesis, FASII, is a target for development of new anti-staphylococcal drugs. This strategy is based on previous reports indicating that self-synthesized fatty acids appear to be indispensable for Staphylococcus aureus growth and virulence, although other bacteria can use exogenous fatty acids to compensate FASII inhibition. Here we report that staphylococci can become resistant to the FASII-targeted inhibitor triclosan via high frequency mutations in fabD, one of the FASII genes. The fabD mutants can be conditional for FASII and not require exogenous fatty acids for normal growth, and can use diverse fatty acid combinations (including host fatty acids) when FASII is blocked. These mutants show cross-resistance to inhibitors of other FASII enzymes and are infectious in mice. Clinical isolates bearing fabD polymorphisms also bypass FASII inhibition. We propose that fatty acid-rich environments within the host, in the presence of FASII inhibitors, might favour the emergence of staphylococcal strains displaying resistance to multiple FASII inhibitors.

AB - Weyl points, as monopoles of Berry curvature in momentum space, have captured much attention recently in various branches of physics. Realizing topological materials that exhibit such nodal points is challenging and indeed, Weyl points have been found experimentally in transition metal arsenide and phosphide and gyroid photonic crystal whose structure is complex. If realizing even the simplest type of single Weyl nodes with a topological charge of 1 is difficult, then making a real crystal carrying higher topological charges may seem more challenging. Here we design, and fabricate using planar fabrication technology, a photonic crystal possessing single Weyl points (including type-II nodes) and multiple Weyl points with topological charges of 2 and 3. We characterize this photonic crystal and find nontrivial 2D bulk band gaps for a fixed kz and the associated surface modes. The robustness of these surface states against kz preserving scattering is experimentally observed for the first time. PMID- 27703141 TI - Pre-eruptive magmatic processes re-timed using a non-isothermal approach to magma chamber dynamics. AB - Constraining the timescales of pre-eruptive magmatic processes in active volcanic systems is paramount to understand magma chamber dynamics and the triggers for volcanic eruptions. Temporal information of magmatic processes is locked within the chemical zoning profiles of crystals but can be accessed by means of elemental diffusion chronometry. Mineral compositional zoning testifies to the occurrence of substantial temperature differences within magma chambers, which often bias the estimated timescales in the case of multi-stage zoned minerals. Here we propose a new Non-Isothermal Diffusion Incremental Step model to take into account the non-isothermal nature of pre-eruptive processes, deconstructing the main core-rim diffusion profiles of multi-zoned crystals into different isothermal steps. The Non-Isothermal Diffusion Incremental Step model represents a significant improvement in the reconstruction of crystal lifetime histories. Unravelling stepwise timescales at contrasting temperatures provides a novel approach to constraining pre-eruptive magmatic processes and greatly increases our understanding of magma chamber dynamics. PMID- 27703143 TI - Observation of pendular butterfly Rydberg molecules. AB - Engineering molecules with a tunable bond length and defined quantum states lies at the heart of quantum chemistry. The unconventional binding mechanism of Rydberg molecules makes them a promising candidate to implement such tunable molecules. A very peculiar type of Rydberg molecules are the so-called butterfly molecules, which are bound by a shape resonance in the electron-perturber scattering. Here we report the observation of these exotic molecules and employ their exceptional properties to engineer their bond length, vibrational state, angular momentum and orientation in a small electric field. Combining the variable bond length with their giant dipole moment of several hundred Debye, we observe counter-intuitive molecules which locate the average electron position beyond the internuclear distance. PMID- 27703142 TI - Prokineticin-2 upregulation during neuronal injury mediates a compensatory protective response against dopaminergic neuronal degeneration. AB - Prokineticin-2 (PK2), a recently discovered secreted protein, regulates important physiological functions including olfactory biogenesis and circadian rhythms in the CNS. Interestingly, although PK2 expression is low in the nigral system, its receptors are constitutively expressed on nigrostriatal neurons. Herein, we demonstrate that PK2 expression is highly induced in nigral dopaminergic neurons during early stages of degeneration in multiple models of Parkinson's disease (PD), including PK2 reporter mice and MitoPark mice. Functional studies demonstrate that PK2 promotes mitochondrial biogenesis and activates ERK and Akt survival signalling pathways, thereby driving neuroprotection. Importantly, PK2 overexpression is protective whereas PK2 receptor antagonism exacerbates dopaminergic degeneration in experimental PD. Furthermore, PK2 expression increased in surviving nigral dopaminergic neurons from PD brains, indicating that PK2 upregulation is clinically relevant to human PD. Collectively, our results identify a paradigm for compensatory neuroprotective PK2 signalling in nigral dopaminergic neurons that could have important therapeutic implications for PD. PMID- 27703144 TI - Bmi1 marks distinct castration-resistant luminal progenitor cells competent for prostate regeneration and tumour initiation. AB - Identification of defined cell populations with stem/progenitor properties is key for understanding prostate development and tumorigenesis. Here we show that the polycomb repressor protein Bmi1 marks a population of castration-resistant luminal epithelial cells enriched in the mouse proximal prostate. We employ lineage tracing to show that these castration-resistant Bmi1-expressing cells (or CARBs) are capable of tissue regeneration and self-renewal. Notably, CARBs are distinct from the previously described luminal castration-resistant Nkx3.1 expressing cells (CARNs). CARBs can serve as a prostate cancer cell-of-origin upon Pten deletion, yielding luminal prostate tumours. Clonal analysis using the R26R-confetti allele indicates preferential tumour initiation from CARBs localized to the proximal prostate. These studies identify Bmi1 as a marker for a distinct population of castration-resistant luminal epithelial cells enriched in the proximal prostate that can serve as a cell of origin for prostate cancer. PMID- 27703145 TI - Biobank attributes associated with higher patient participation: a randomized study. AB - The objectives of the study were to assess patients' intent to participate in a hospital-based biobank and to explore the factors associated with higher participation. A 23-item questionnaire was developed to survey a random sample of patients in a Swiss university hospital. Two vignettes describing hypothetical biobanks were incorporated in the survey and patients were asked whether they would agree to participate. Three factors were randomly manipulated in each vignette using a factorial design: cancer-oriented research vs general consent, one vs several reviews of the patient's chart, and genetic vs blood protein analyses (first vignette); blood sample vs oral swabbing, local vs international project, and a follow-up visit vs no visit (second vignette). Of the 1140 respondents, 73.6 and 69.6%, respectively, agreed to participate in the biobank. Biospecimen collection via oral swabbing, single chart review, and no follow-up were associated with higher participation. Participation was also higher among younger patients, Europeans, patients who had a positive opinion on research, and blood/organ donors. Biobanking was supported by a majority of patients, especially if biospecimens were collected through non-invasive techniques or if data collection was done once. The scope of consent, the scale of the project, or the tests performed on biospecimens did not influence participation. PMID- 27703146 TI - Improving the in silico assessment of pathogenicity for compensated variants. AB - Understanding the functional sequelae of amino-acid replacements is of fundamental importance in medical genetics. Perhaps, the most intuitive way to assess the potential pathogenicity of a given human missense variant is by measuring the degree of evolutionary conservation of the substituted amino-acid residue, a feature that generally serves as a good proxy metric for the functional/structural importance of that residue. However, the presence of putatively compensated variants as the wild-type alleles in orthologous proteins of other mammalian species not only challenges this classical view of amino-acid essentiality but also precludes the accurate evaluation of the functional impact of this type of missense variant using currently available bioinformatic prediction tools. Compensated variants constitute at least 4% of all known missense variants causing human-inherited disease and hence represent an important potential source of error in that they are likely to be disproportionately misclassified as benign variants. The consequent under reporting of compensated variants is exacerbated in the context of next generation sequencing where their inappropriate exclusion constitutes an unfortunate natural consequence of the filtering and prioritization of the very large number of variants generated. Here we demonstrate the reduced performance of currently available pathogenicity prediction tools when applied to compensated variants and propose an alternative machine-learning approach to assess likely pathogenicity for this particular type of variant. PMID- 27703147 TI - Variants in SKP1, PROB1, and IL17B genes at keratoconus 5q31.1-q35.3 susceptibility locus identified by whole-exome sequencing. AB - Keratoconus (KTCN) is a protrusion and thinning of the cornea, resulting in impairment of visual function. The extreme genetic heterogeneity makes it difficult to discover factors unambiguously influencing the KTCN phenotype. In this study, we used whole-exome sequencing (WES) and Sanger sequencing to reduce the number of candidate genes at the 5q31.1-q35.3 locus and to prioritize other potentially relevant variants in an Ecuadorian family with KTCN. We applied WES in two affected KTCN individuals from the Ecuadorian family that showed a suggestive linkage between the KTCN phenotype and the 5q31.1-q35.3 locus. Putative variants identified by WES were further evaluated in this family using Sanger sequencing. Exome capture discovered a total of 173 rare (minor allele frequency <0.001 in control population) nonsynonymous variants in both affected individuals. Among them, 16 SNVs were selected for further evaluation. Segregation analysis revealed that variants c.475T>G in SKP1, c.671G>A in PROB1, and c.527G>A in IL17B in the 5q31.1-q35.3 linkage region, and c.850G>A in HKDC1 in the 10q22 locus completely segregated with the phenotype in the studied KTCN family. We demonstrate that a combination of various techniques significantly narrowed the studied genomic region and reduced the list of the putative exonic variants. Moreover, since this locus overlapped two other chromosomal regions previously recognized in distinct KTCN studies, our findings suggest that this 5q31.1-q35.3 locus might be linked with KTCN. PMID- 27703148 TI - The origin of efficient triplet state population in sulfur-substituted nucleobases. AB - Elucidating the photophysical mechanisms in sulfur-substituted nucleobases (thiobases) is essential for designing prospective drugs for photo- and chemotherapeutic applications. Although it has long been established that the phototherapeutic activity of thiobases is intimately linked to efficient intersystem crossing into reactive triplet states, the molecular factors underlying this efficiency are poorly understood. Herein we combine femtosecond transient absorption experiments with quantum chemistry and nonadiabatic dynamics simulations to investigate 2-thiocytosine as a necessary step to unravel the electronic and structural elements that lead to ultrafast and near-unity triplet state population in thiobases in general. We show that different parts of the potential energy surfaces are stabilized to different extents via thionation, quenching the intrinsic photostability of canonical DNA and RNA nucleobases. These findings satisfactorily explain why thiobases exhibit the fastest intersystem crossing lifetimes measured to date among bio-organic molecules and have near-unity triplet yields, whereas the triplet yields of canonical nucleobases are nearly zero. PMID- 27703149 TI - Variation in urinary spot sample, 24 h samples, and longer-term average urinary concentrations of short-lived environmental chemicals: implications for exposure assessment and reverse dosimetry. AB - Population biomonitoring data sets such as the Canadian Health Measures Survey (CHMS) and the United States National Health and Nutrition Examination Survey (NHANES) collect and analyze spot urine samples for analysis for biomarkers of exposure to non-persistent chemicals. Estimation of population intakes using such data sets in a risk-assessment context requires consideration of intra- and inter individual variability to understand the relationship between variation in the biomarker concentrations and variation in the underlying daily and longer-term intakes. Two intensive data sets with a total of 16 individuals with collection and measurement of serial urine voids over multiple days were used to examine these relationships using methyl paraben, triclosan, bisphenol A (BPA), monoethyl phthalate (MEP), and mono-2-ethylhexyl hydroxyl phthalate (MEHHP) as example compounds. Composited 24 h voids were constructed mathematically from the individual collected voids, and concentrations for each 24 h period and average multiday concentrations were calculated for each individual in the data sets. Geometric mean and 95th percentiles were compared to assess the relationship between distributions in spot sample concentrations and the 24 h and multiday collection averages. In these data sets, spot sample concentrations at the 95th percentile were similar to or slightly higher than the 95th percentile of the distribution of all 24 h composite void concentrations, but tended to overestimate the maximum of the multiday concentration averages for most analytes (usually by less than a factor of 2). These observations can assist in the interpretation of population distributions of spot samples for frequently detected analytes with relatively short elimination half-lives. PMID- 27703151 TI - Repeating microearthquake sequences interact predominantly through postseismic slip. AB - Studying small repeating earthquakes enables better understanding of fault physics and characterization of fault friction properties. Some of the nearby repeating sequences appear to interact, such as the 'San Francisco' and 'Los Angeles' repeaters on the creeping section of the San Andreas Fault. It is typically assumed that such interactions are induced by static stress changes due to coseismic slip. Here we present a study of the interaction of repeating earthquakes in the framework of rate-and-state fault models using state-of-the art simulation methods that reproduce both realistic seismic events and long-term earthquake sequences. Our simulations enable comparison among several types of stress transfer that occur between the repeating events. Our major finding is that postseismic creep dominates the interaction, with earthquake triggering occurring at distances much larger than typically assumed. Our results open a possibility of using interaction of repeating sequences to constrain friction properties of creeping segments. PMID- 27703150 TI - Genomic and oncogenic preference of HBV integration in hepatocellular carcinoma. AB - Hepatitis B virus (HBV) can integrate into the human genome, contributing to genomic instability and hepatocarcinogenesis. Here by conducting high-throughput viral integration detection and RNA sequencing, we identify 4,225 HBV integration events in tumour and adjacent non-tumour samples from 426 patients with HCC. We show that HBV is prone to integrate into rare fragile sites and functional genomic regions including CpG islands. We observe a distinct pattern in the preferential sites of HBV integration between tumour and non-tumour tissues. HBV insertional sites are significantly enriched in the proximity of telomeres in tumours. Recurrent HBV target genes are identified with few that overlap. The overall HBV integration frequency is much higher in tumour genomes of males than in females, with a significant enrichment of integration into chromosome 17. Furthermore, a cirrhosis-dependent HBV integration pattern is observed, affecting distinct targeted genes. Our data suggest that HBV integration has a high potential to drive oncogenic transformation. PMID- 27703152 TI - Thermopile detector of light ellipticity. AB - Polarimetric imaging is widely used in applications from material analysis to biomedical diagnostics, vision and astronomy. The degree of circular polarization, or light ellipticity, is associated with the S3 Stokes parameter which is defined as the difference in the intensities of the left- and right circularly polarized components of light. Traditional way of determining this parameter relies on using several external optical elements, such as polarizers and wave plates, along with conventional photodetectors, and performing at least two measurements to distinguish left- and right-circularly polarized light components. Here we theoretically propose and experimentally demonstrate a thermopile photodetector element that provides bipolar voltage output directly proportional to the S3 Stokes parameter of the incident light. PMID- 27703154 TI - Local adaptation (mostly) remains local: reassessing environmental associations of climate-related candidate SNPs in Arabidopsis halleri. AB - Numerous landscape genomic studies have identified single-nucleotide polymorphisms (SNPs) and genes potentially involved in local adaptation. Rarely, it has been explicitly evaluated whether these environmental associations also hold true beyond the populations studied. We tested whether putatively adaptive SNPs in Arabidopsis halleri (Brassicaceae), characterized in a previous study investigating local adaptation to a highly heterogeneous environment, show the same environmental associations in an independent, geographically enlarged set of 18 populations. We analysed new SNP data of 444 plants with the same methodology (partial Mantel tests, PMTs) as in the original study and additionally with a latent factor mixed model (LFMM) approach. Of the 74 candidate SNPs, 41% (PMTs) and 51% (LFMM) were associated with environmental factors in the independent data set. However, only 5% (PMTs) and 15% (LFMM) of the associations showed the same environment-allele relationships as in the original study. In total, we found 11 genes (31%) containing the same association in the original and independent data set. These can be considered prime candidate genes for environmental adaptation at a broader geographical scale. Our results suggest that selection pressures in highly heterogeneous alpine environments vary locally and signatures of selection are likely to be population-specific. Thus, genotype-by-environment interactions underlying adaptation are more heterogeneous and complex than is often assumed, which might represent a problem when testing for adaptation at specific loci. PMID- 27703153 TI - Heritable symbionts in a world of varying temperature. AB - Heritable microbes represent an important component of the biology, ecology and evolution of many plants, animals and fungi, acting as both parasites and partners. In this review, we examine how heritable symbiont-host interactions may alter host thermal tolerance, and how the dynamics of these interactions may more generally be altered by thermal environment. Obligate symbionts, those required by their host, are considered to represent a thermally sensitive weak point for their host, associated with accumulation of deleterious mutations. As such, these symbionts may represent an important determinant of host thermal envelope and spatial distribution. We then examine the varied relationship between thermal environment and the frequency of facultative symbionts that provide ecologically contingent benefits or act as parasites. We note that some facultative symbionts directly alter host thermotolerance. We outline how thermal environment will alter the benefits/costs of infection more widely, and additionally modulate vertical transmission efficiency. Multiple patterns are observed, with symbionts being cold sensitive in some species and heat sensitive in others, with varying and non-coincident thresholds at which phenotype and transmission are ablated. Nevertheless, it is clear that studies aiming to predict ecological and evolutionary dynamics of symbiont-host interactions need to examine the interaction across a range of thermal environments. Finally, we discuss the importance of thermal sensitivity in predicting the success/failure of symbionts to spread into novel species following natural/engineered introduction. PMID- 27703155 TI - Persistence of long-distance, insect-mediated pollen movement for a tropical canopy tree species in remnant forest patches in an urban landscape. AB - As deforestation and urbanization continue at rapid rates in tropical regions, urban forest patches are essential repositories of biodiversity. However, almost nothing is known about gene flow of forest-dependent tree species in urban landscapes. In this study, we investigated gene flow in the insect-pollinated, wind-dispersed tropical tree Koompassia malaccensis in and among three remnant forest patches in the urbanized landscape of Singapore. We genotyped the vast majority of adults (N=179) and a large number of recruits (N=2103) with 8 highly polymorphic microsatellite markers. Spatial genetic structure of the recruit and adult cohorts was significant, showing routine gene dispersal distances of ~100 400 m. Parentage analysis showed that 97% of recruits were within 100 m of their mother tree, and a high frequency of relatively short-distance pollen dispersal (median ~143-187 m). Despite routine seed and pollen dispersal distances of within a few hundred meters, interpatch gene flow occurred between all patches and was dominated by pollen movement: parentage analysis showed 76 pollen versus 2 seed interpatch dispersal events, and the seedling neighborhood model estimated ~1-6% seed immigration and ~21-46% pollen immigration rates, depending on patch. In addition, the smallest patch (containing five adult K. malaccensis trees) was entirely surrounded by >2.5 km of 'impervious' substrate, yet had the highest proportional pollen and seed immigration estimates of any patch. Hence, contrary to our hypothesis, insect-mediated gene flow persisted across an urban landscape, and several of our results also parallel key findings from insect-pollinated canopy trees sampled in mixed agricultural-forest landscapes. PMID- 27703157 TI - Animal diversity and ecosystem functioning in dynamic food webs. AB - Species diversity is changing globally and locally, but the complexity of ecological communities hampers a general understanding of the consequences of animal species loss on ecosystem functioning. High animal diversity increases complementarity of herbivores but also increases feeding rates within the consumer guild. Depending on the balance of these counteracting mechanisms, species-rich animal communities may put plants under top-down control or may release them from grazing pressure. Using a dynamic food-web model with body-mass constraints, we simulate ecosystem functions of 20,000 communities of varying animal diversity. We show that diverse animal communities accumulate more biomass and are more exploitative on plants, despite their higher rates of intra-guild predation. However, they do not reduce plant biomass because the communities are composed of larger, and thus energetically more efficient, plant and animal species. This plasticity of community body-size structure reconciles the debate on the consequences of animal species loss for primary productivity. PMID- 27703158 TI - Three structurally-related impurities in norvancomycin drug substance. AB - Norvancomycin (NVCM) is widely used in China to treat bacterial infections of Gram-positive cocci and bacilli, especially infections of methicillin-resistant Staphylococcus aureus and methicillin-resistant Staphylococcus epidermidis. This study is a chemical investigation of the drug substance of NVCM, and led to the identification, by 1D, 2D NMR spectra and HRESIMS, of three as yet undescribed impurities, one D-O-E ring expanded NVCM analog (1) and two derivatives of NVCM lacking sugars (2, 3). PMID- 27703159 TI - Synthesis and structure-activity relationships of novel lincomycin derivatives part 3: discovery of the 4-(pyrimidin-5-yl)phenyl group in synthesis of 7(S) thiolincomycin analogs. AB - Novel lincomycin derivatives possessing an aryl phenyl group or a heteroaryl phenyl group at the C-7 position via sulfur atom were synthesized by Pd-catalyzed cross-coupling reactions of 7(S)-7-deoxy-7-thiolincomycin (5) with various aryl halides. This reaction is the most useful method to synthesize a variety of 7(S) 7-deoxy-7-thiolincomycin derivatives. On the basis of analysis of structure activity relationships of these novel lincomycin derivatives, we found that (a) the location of basicity in the C-7 side chain was an important factor to enhance antibacterial activities, and (b) compounds 22, 36, 42, 43 and 44 had potent antibacterial activities against a variety of Streptococcus pneumoniae with erm gene, which cause severe respiratory infections, even compared with our C-7 modified lincomycin analogs (1-4) reported previously. Furthermore, 7(S) configuration was found to be necessary for enhancing antibacterial activities from comparison of configurations at the 7-position of 36 (S-configuration) and 41 (R-configuration). PMID- 27703156 TI - Genome-wide compendium and functional assessment of in vivo heart enhancers. AB - Whole-genome sequencing is identifying growing numbers of non-coding variants in human disease studies, but the lack of accurate functional annotations prevents their interpretation. We describe the genome-wide landscape of distant-acting enhancers active in the developing and adult human heart, an organ whose impairment is a predominant cause of mortality and morbidity. Using integrative analysis of >35 epigenomic data sets from mouse and human pre- and postnatal hearts we created a comprehensive reference of >80,000 putative human heart enhancers. To illustrate the importance of enhancers in the regulation of genes involved in heart disease, we deleted the mouse orthologs of two human enhancers near cardiac myosin genes. In both cases, we observe in vivo expression changes and cardiac phenotypes consistent with human heart disease. Our study provides a comprehensive catalogue of human heart enhancers for use in clinical whole-genome sequencing studies and highlights the importance of enhancers for cardiac function. PMID- 27703162 TI - New national data show alarming increase in obesity and noncommunicable chronic diseases in China. PMID- 27703160 TI - Elucidation of the biosynthesis of carnosic acid and its reconstitution in yeast. AB - Rosemary extracts containing the phenolic diterpenes carnosic acid and its derivative carnosol are approved food additives used in an increasingly wide range of products to enhance shelf-life, thanks to their high anti-oxidant activity. We describe here the elucidation of the complete biosynthetic pathway of carnosic acid and its reconstitution in yeast cells. Cytochrome P450 oxygenases (CYP76AH22-24) from Rosmarinus officinalis and Salvia fruticosa already characterized as ferruginol synthases are also able to produce 11 hydroxyferruginol. Modelling-based mutagenesis of three amino acids in the related ferruginol synthase (CYP76AH1) from S. miltiorrhiza is sufficient to convert it to a 11-hydroxyferruginol synthase (HFS). The three sequential C20 oxidations for the conversion of 11-hydroxyferruginol to carnosic acid are catalysed by the related CYP76AK6-8. The availability of the genes for the biosynthesis of carnosic acid opens opportunities for the metabolic engineering of phenolic diterpenes, a class of compounds with potent anti-oxidant, anti inflammatory and anti-tumour activities. PMID- 27703161 TI - Intake of vitamin B before onset of Parkinson's disease and atypical parkinsonism and olfactory function at the time of diagnosis. AB - BACKGROUND/OBJECTIVES: To investigate whether vitamin-B density in the diet 2-8 years before diagnosis is associated with olfactory function at the time of diagnosis. SUBJECTS/METHODS: This prospective nested case-control study included patients with Parkinson's disease (PD), multiple system atrophy and progressive supranuclear paralysis identified between 2004 and 2009 in the county of Vasterbotten in northern Sweden. The case database (NYPUM study; Newly Diagnosed Parkinson in Umea; n=147) was cross-linked to the Northern Sweden Health and Disease Study (NSHDS). Identified patients (n=96) and controls (n=375) were matched for sex, age, year of health survey, sub-cohort and geographical area. Dietary intake was assessed by a food frequency questionnaire, and the brief smell identification test (B-SIT) was used to measure olfactory function at the time of diagnosis. RESULTS: There was no difference in vitamin-B or any other macro- or micro-nutrient densities, energy intake or body mass index (kg/m2; BMI) between patients and controls at baseline at the time of the healthcare survey. A lower thiamin and folate density, amount per 1 megajoule, was reported in patients who scored below median on B-SIT (<7) when compared with that in patients who scored ?7 at the time of diagnosis. After adjusting for age, sex and BMI using linear and logistic regressions, an even stronger association was found between thiamin density and olfactory function. CONCLUSIONS: A low thiamin and folate density in the reported diet, 2-8 years before PD diagnosis, was significantly associated with olfactory dysfunction at the time of PD diagnosis. PMID- 27703163 TI - Accuracy of non-paralytic anthropometric data for nutritional screening in older patients with stroke and hemiplegia. AB - BACKGROUND/OBJECTIVES: Although malnutrition commonly affects stroke patients, there are no validated screening tools. We verified the usefulness of non paralytic anthropometric measurements for the nutritional screening of stroke. SUBJECTS/METHODS: A cross-sectional study was conducted in consecutive stroke patients with hemiplegia aged ?65 years, with Mini Nutritional Assessment Short Form score ?11. Diagnostic malnutrition criteria from the European Society for Clinical Nutrition and Metabolism were the reference standards: body mass index (BMI) <18.5 kg/m2 or weight loss >10%+BMI <22 or 20 kg/m2. Non-paralytic anthropometric measurements (calf circumference (CC), arm circumference (AC), triceps skinfold (TSF) and arm muscle circumference (AMC)) and serum albumin concentration (Alb) at admission were the index tests. Cutoffs were determined by receiver operation curve and Youden index, and accuracy by area under the curve (AUC) and kappa value. Functional independence measures at discharge and discharge destination were collected. RESULTS: We included 488 patients (224 men and 264 women) with a mean age of 78.8 years and mean BMI of 22.0 and 21.1 kg/m2, respectively. Eighty-one men and 124 women had malnutrition. The AUC for CC, AC, TSF, AMC and Alb was 0.859, 0.825, 0.764, 0.745 and 0.670 for men, and 0.881, 0.843, 0.796, 0.742 and 0.658 for women, respectively. In both sexes, CC had the highest kappa (0.533, 0.608; both P<0.001) with cutoff values ?31 and ?30 cm. Patients with lower CC showed significantly worse functional outcomes and lower proportion of return to home (P<0.001). CONCLUSIONS: Non-paralytic CC indicated malnutrition with sufficient accuracy and good correlation with functional capacity; it may be a useful nutritional screening tool for stroke. PMID- 27703164 TI - Analogue modulation of back-propagating action potentials enables dendritic hybrid signalling. AB - We report that back-propagating action potentials (bAPs) are not simply digital feedback signals in dendrites but also carry analogue information about the overall state of neurons. Analogue information about the somatic membrane potential within a physiological range (from -78 to -64 mV) is retained by bAPs of dentate gyrus granule cells as different repolarization speeds in proximal dendrites and as different peak amplitudes in distal regions. These location dependent waveform changes are reflected by local calcium influx, leading to proximal enhancement and distal attenuation during somatic hyperpolarization. The functional link between these retention and readout mechanisms of the analogue content of bAPs critically depends on high-voltage-activated, inactivating calcium channels. The hybrid bAP and calcium mechanisms report the phase of physiological somatic voltage fluctuations and modulate long-term synaptic plasticity in distal dendrites. Thus, bAPs are hybrid signals that relay somatic analogue information, which is detected by the dendrites in a location-dependent manner. PMID- 27703165 TI - Boosted output performance of triboelectric nanogenerator via electric double layer effect. AB - For existing triboelectric nanogenerators (TENGs), it is important to explore unique methods to further enhance the output power under realistic environments to speed up their commercialization. We report here a practical TENG composed of three layers, in which the key layer, an electric double layer, is inserted between a top layer, made of Al/polydimethylsiloxane, and a bottom layer, made of Al. The efficient charge separation in the middle layer, based on Volta's electrophorus, results from sequential contact configuration of the TENG and direct electrical connection of the middle layer to the earth. A sustainable and enhanced output performance of 1.22 mA and 46.8 mW cm-2 under low frequency of 3 Hz is produced, giving over 16-fold enhancement in output power and corresponding to energy conversion efficiency of 22.4%. Finally, a portable power-supplying system, which provides enough d.c. power for charging a smart watch or phone battery, is also successfully developed. PMID- 27703166 TI - Structure sensitivity of Cu and CuZn catalysts relevant to industrial methanol synthesis. AB - For decades it has been debated whether the conversion of synthesis gas to methanol over copper catalysts is sensitive or insensitive to the structure of the copper surface. Here we have systematically investigated the effect of the copper particle size in the range where changes in surface structure occur, that is, below 10 nm, for catalysts with and without zinc promotor at industrially relevant conditions for methanol synthesis. Regardless of the presence or absence of a zinc promotor in the form of zinc oxide or zinc silicate, the surface specific activity decreases significantly for copper particles smaller than 8 nm, thus revealing structure sensitivity. In view of recent theoretical studies we propose that the methanol synthesis reaction takes place at copper surface sites with a unique configuration of atoms such as step-edge sites, which smaller particles cannot accommodate.

AB - DNA double-strand breaks (DSBs) leading to loss of nucleotides in the transcribed region can be lethal. Classical non-homologous end-joining (C-NHEJ) is the dominant pathway for DSB repair (DSBR) in adult mammalian cells. Here we report that during such DSBR, mammalian C-NHEJ proteins form a multiprotein complex with RNA polymerase II and preferentially associate with the transcribed genes after DSB induction. Depletion of C-NHEJ factors significantly abrogates DSBR in transcribed but not in non-transcribed genes. We hypothesized that nascent RNA can serve as a template for restoring the missing sequences, thus allowing error free DSBR. We indeed found pre-mRNA in the C-NHEJ complex. Finally, when a DSB containing plasmid with several nucleotides deleted within the E. coli lacZ gene was allowed time to repair in lacZ-expressing mammalian cells, a functional lacZ plasmid could be recovered from control but not C-NHEJ factor-depleted cells, providing important mechanistic insights into C-NHEJ-mediated error-free DSBR of the transcribed genome.

AB - The sign and magnitude of permafrost carbon (C)-climate feedback are highly uncertain due to the limited understanding of the decomposability of thawing permafrost and relevant mechanistic controls over C release. Here, by combining aerobic incubation with biomarker analysis and a three-pool model, we reveal that C quality (represented by a higher amount of fast cycling C but a lower amount of recalcitrant C compounds) and normalized CO2-C release in permafrost deposits were similar or even higher than those in the active layer, demonstrating a high vulnerability of C in Tibetan upland permafrost. We also illustrate that C quality exerts the most control over CO2-C release from the active layer, whereas soil microbial abundance is more directly associated with CO2-C release after permafrost thaw. Taken together, our findings highlight the importance of incorporating microbial properties into Earth System Models when predicting permafrost C dynamics under a changing environment. PMID- 27703169 TI - A key process controlling the wet removal of aerosols: new observational evidence. AB - The lifetime and spatial distributions of accumulation-mode aerosols in a size range of approximately 0.05-1 MUm, and thus their global and regional climate impacts, are primarily constrained by their removal via cloud and precipitation (wet removal). However, the microphysical process that predominantly controls the removal efficiency remains unidentified because of observational difficulties. Here, we demonstrate that the activation of aerosols to cloud droplets (nucleation scavenging) predominantly controls the wet removal efficiency of accumulation-mode aerosols, using water-insoluble black carbon as an observable particle tracer during the removal process. From simultaneous ground-based observations of black carbon in air (prior to removal) and in rainwater (after removal) in Tokyo, Japan, we found that the wet removal efficiency depends strongly on particle size, and the size dependence can be explained quantitatively by the observed size-dependent cloud-nucleating ability. Furthermore, our observational method provides an estimate of the effective supersaturation of water vapour in precipitating cloud clusters, a key parameter controlling nucleation scavenging. These novel data firmly indicate the importance of quantitative numerical simulations of the nucleation scavenging process to improve the model's ability to predict the atmospheric aerosol burden and the resultant climate forcings, and enable a new validation of such simulations. PMID- 27703170 TI - A cytosolic carbonic anhydrase molecular switch occurs in the gills of metamorphic sea lamprey. AB - Carbonic anhydrase plays a key role in CO2 transport, acid-base and ion regulation and metabolic processes in vertebrates. While several carbonic anhydrase isoforms have been identified in numerous vertebrate species, basal lineages such as the cyclostomes have remained largely unexamined. Here we investigate the repertoire of cytoplasmic carbonic anhydrases in the sea lamprey (Petromyzon marinus), that has a complex life history marked by a dramatic metamorphosis from a benthic filter-feeding ammocoete larvae into a parasitic juvenile which migrates from freshwater to seawater. We have identified a novel carbonic anhydrase gene (ca19) beyond the single carbonic anhydrase gene (ca18) that was known previously. Phylogenetic analysis and synteny studies suggest that both carbonic anhydrase genes form one or two independent gene lineages and are most likely duplicates retained uniquely in cyclostomes. Quantitative PCR of ca19 and ca18 and protein expression in gill across metamorphosis show that the ca19 levels are highest in ammocoetes and decrease during metamorphosis while ca18 shows the opposite pattern with the highest levels in post-metamorphic juveniles. We propose that a unique molecular switch occurs during lamprey metamorphosis resulting in distinct gill carbonic anhydrases reflecting the contrasting life modes and habitats of these life-history stages. PMID- 27703171 TI - Metabolomic Analysis of Mouse Embryonic Fibroblast Cells in Response to Autophagy Induced by Acute Starvation. AB - Autophagy-related protein 7 (Atg7) is essential in the formation of the autophagophore and is indispensable for autophagy induction. Autophagy will exist in lower level or even be blocked in cells without Atg7. Even though the possible signaling pathways of Atg7 have been proposed, the metabolomic responses under acute starvation in cells with and without Atg7 have not been elucidated. This study therefore was designed and aimed to reveal the metabolomics of Atg7 dependent autophagy through metabolomic analysis of Atg7-/- mouse embryonic fibroblast cells (MEFs) and wild-type MEFs along with the starvation time. 30 significantly altered metabolites were identified in response to nutrient stress, which were mainly associated with amino acid, energy, carbohydrate, and lipid metabolism. For the wild-type MEFs, the induction of autophagy protected cell survival with some up-regulated lipids during the first two hours' starvation, while the subsequent apoptosis resulted in the decrease of cell viability after four hours' starvation. For the Atg7-/- MEFs, apoptosis perhaps led to the deactivation of tricarboxylic acid (TCA) cycle due to the lack of autophagy, which resulted in the immediate drop of cellular viability under starvation. These results contributed to the metabolomic study and provided new insights into the mechanism associated with Atg7-dependent autophagy. PMID- 27703172 TI - A Tetravalent Sub-unit Dengue Vaccine Formulated with Ionizable Cationic Lipid Nanoparticle induces Significant Immune Responses in Rodents and Non-Human Primates. AB - Dengue virus has emerged as an important arboviral infection worldwide. As a complex pathogen, with four distinct serotypes, the development of a successful Dengue virus vaccine has proven to be challenging. Here, we describe a novel Dengue vaccine candidate that contains truncated, recombinant, Dengue virus envelope protein from all four Dengue virus serotypes (DEN-80E) formulated with ionizable cationic lipid nanoparticles (LNPs). Immunization studies in mice, Guinea pigs, and in Rhesus macaques, revealed that LNPs induced high titers of Dengue virus neutralizing antibodies, with or without co-administration or encapsulation of a Toll-Like Receptor 9 agonist. Importantly, LNPs were also able to boost DEN-80E specific CD4+ and CD8+ T cell responses. Cytokine and chemokine profiling revealed that LNPs induced strong chemokine responses without significant induction of inflammatory cytokines. In addition to being highly efficacious, the vaccine formulation proved to be well-tolerated, demonstrating no elevation in any of the safety parameters evaluated. Notably, reduction in cationic lipid content of the nanoparticle dramatically reduced the LNP's ability to boost DEN-80E specific immune responses, highlighting the crucial role for the charge of the LNP. Overall, our novel studies, across multiple species, reveal a promising tetravalent Dengue virus sub-unit vaccine candidate. PMID- 27703174 TI - Light-Controlled ZrO2 Surface Hydrophilicity. AB - In recent years many works are aimed at finding a method of controllable switching between hydrophilicity and hydrophobicity of a surface. The hydrophilic surface state is generally determined by its energy. Change in the surface energy can be realized in several different ways. Here we report the ability to control the surface wettability of zirconium dioxide nano-coatings by changing the composition of actinic light. Such unique photoinduced hydrophilic behavior of ZrO2 surface is ascribed to the formation of different active surface states under photoexcitation in intrinsic and extrinsic ZrO2 absorption regions. The sequential effect of different actinic lights on the surface hydrophilicity of zirconia is found to be repeatable and reversibly switchable from a highly hydrophilic state to a more hydrophobic state. The observed light-controllable reversible and reproducible switching of hydrophilicity opens new possible ways for the application of ZrO2 based materials. PMID- 27703173 TI - Risk of prenatal depression and stress treatment: alteration on serotonin system of offspring through exposure to Fluoxetine. AB - Fluoxetine is widely used to treat depression, including depression in pregnant and postpartum women. Studies suggest that fluoxetine may have adverse effects on offspring, presumably through its action on various serotonin receptors (HTRs). However, definitive evidence and the underlying mechanisms are largely unavailable. As initial steps towards establishing a human cellular and animal model, we analyzed the expression patterns of several HTRs through the differentiation of human induced pluripotent stem (hiPS) cells into neuronal cells, and analyzed expression pattern in zebrafish embryos. Treatment of zebrafish embryos with fluoxetine significantly blocked the expression of multiple HTRs. Furthermore, fluoxetine gave rise to a change in neuropsychology. Embryos treated with fluoxetine continued to exhibit abnormal behavior upto 12 days post fertilization due to changes in HTRs. These findings support a possible long-term risk of serotonin pathway alteration, possibly resulting from the "placental drug transfer". PMID- 27703176 TI - Large Absorption Enhancement in Ultrathin Solar Cells Patterned by Metallic Nanocavity Arrays. AB - A new type of light trapping structure utilizing ring-shaped metallic nanocavity arrays is proposed for the absorption enhancement in ultrathin solar cells with few photonic waveguide modes. Dozens of times of broadband absorption enhancement in the spectral range of 700 to 1100 nm is demonstrated in an ultrathin Si3N4/c Si/Ag prototype solar cell by means of finite-difference time-domain (FDTD) simulation, and this dramatic absorption enhancement can be attributed to the excitation of plasmonic cavity modes in these nanocavity arrays. The cavity modes optimally compensate for the lack of resonances in the longer wavelength range for ultrathin solar cells, and eventually a maximum Jsc enhancement factor of 2.15 is achieved under AM 1.5G solar illumination. This study opens a new perspective for light management in thin film solar cells and other optoelectronic devices. PMID- 27703175 TI - Paracrine Effects of Adipose-Derived Stem Cells on Matrix Stiffness-Induced Cardiac Myofibroblast Differentiation via Angiotensin II Type 1 Receptor and Smad7. AB - Human mesenchymal stem cells (hMSCs) hold great promise in cardiac fibrosis therapy, due to their potential ability of inhibiting cardiac myofibroblast differentiation (a hallmark of cardiac fibrosis). However, the mechanism involved in their effects remains elusive. To explore this, it is necessary to develop an in vitro cardiac fibrosis model that incorporates pore size and native tissue mimicking matrix stiffness, which may regulate cardiac myofibroblast differentiation. In the present study, collagen coated polyacrylamide hydrogel substrates were fabricated, in which the pore size was adjusted without altering the matrix stiffness. Stiffness is shown to regulate cardiac myofibroblast differentiation independently of pore size. Substrate at a stiffness of 30 kPa, which mimics the stiffness of native fibrotic cardiac tissue, was found to induce cardiac myofibroblast differentiation to create in vitro cardiac fibrosis model. Conditioned medium of hMSCs was applied to the model to determine its role and inhibitory mechanism on cardiac myofibroblast differentiation. It was found that hMSCs secrete hepatocyte growth factor (HGF) to inhibit cardiac myofibroblast differentiation via downregulation of angiotensin II type 1 receptor (AT1R) and upregulation of Smad7. These findings would aid in establishment of the therapeutic use of hMSCs in cardiac fibrosis therapy in future. PMID- 27703177 TI - Necrostatin-1 treatment inhibits osteocyte necroptosis and trabecular deterioration in ovariectomized rats. AB - Estrogen (E2) deficiency has been associated with accelerated osteocyte apoptosis. Our previous study showed necroptosis accelerated the loss of osteocytes in E2 deficiency-induced osteoporosis in rats in addition to apoptosis, but the mechanism involved remains. Necroptosis is a caspase independent form of programmed cell death. In the necroptosis pathway, receptor interaction proteins 1 and 3 (RIP1/3) play vital roles. Necrostatin-1 (Nec-1) has been confirmed to be a specific inhibitor of necroptosis. However, the effect of Nec-1 on postmenopausal osteoporosis remains ambiguous. The aim of this study was to investigate the effect of Nec-1 on osteocytes in ovariectomized (OVX) rats. We found that an increased number of necroptotic osteocytes was related to the production of tumor necrosis factor-alpha (TNF-alpha) in OVX rats. Treatment with Nec-1 significantly decreased RIP1 and RIP3 expression in OVX rats and inhibited osteocyte necroptosis induced by TNF-alpha in vitro. Both E2 and Nec-1 treatment markedly ameliorated trabecular bone deterioration. Nec-1 also significantly elevated the levels of bone formation markers and decreased bone resorption markers. These data suggest that the role of Nec-1 on alleviating bone loss might be associated with Nec-1 restraining TNF-alpha-induced osteocyte necroptosis in rats with E2 deficiency-induced osteoporosis. This process may represent a novel therapeutic strategy for the treatment of postmenopausal osteoporosis. PMID- 27703178 TI - Rapid genomic changes in allopolyploids of Carassius auratus red var. (?) * Megalobrama amblycephala (?). AB - To better understand genomic changes in the early generations after polyploidisation, we examined the chromosomal consequences of genomic merger in allotetraploid hybrids (4 nF1) (AABB, 4n = 148) of Carassius auratus red var. (RCC) (AA, 2n = 100) (?) * Megalobrama amblycephala (BSB) (BB, 2n = 48) (?). Complete loss of the paternal 5S rDNA sequence and the expected number of maternal chromosomal loci were found in 4 nF1, suggesting directional genomic changes occurred in the first generations after polyploidisation. Recent studies have reported instability of newly established allotetraploid genomes. To assess this in the newly formed 4 nF1 genome, we performed fluorescence in situ hybridisation on an allotetraploid gynogenetic hybrid (4 nG) (AABB, 4n = 148) and an allopentaploid hybrid (5 nH) (AABBB, 5n = 172) from 4 nF1 (?) * BSB (?) with 5S rDNA gene and centromere probes from RCC, the original diploid parent. The expected numbers of maternal chromosomal loci were found in 4 nG, while chromosomal locus deletions and chromosome recombinations were detected in 5 nH. These observations suggest that abnormal meiosis did not lead to obvious genomic changes in the newly established allotetraploid genomes, but hybridisation with the original diploid parent resulted in obvious genomic changes in the newly established allotetraploid genomes, as was found for the maternal genome. PMID- 27703180 TI - Room-temperature near-infrared up-conversion lasing in single-crystal Er-Y chloride silicate nanowires. AB - Near-infrared up-conversion lasing in erbium(Er)-yttrium(Y) chloride silicate nanowires was demonstrated when pumped by 1476 nm laser at room temperature. The emission covers a very wide wavelength range (400-1000 nm). A clear threshold for 985 nm peak was observed at a launched average pump power of approximately 7 mW. Above threshold, the intensity increases linearly when turning up the pump power. The full width at half maximum at 985 nm decreases from 1.25 nm to 0.25 nm when reducing the measurement temperature from 30 K to 7 K, which is the narrowest linewidth of 980 nm micro-lasers to date. Our demonstration presents a possible novel method of utilizing up-conversion mechanism in Er-Y nanowire to achieve tunable near-infrared laser, which breaks new ground in the exploration of nanoscale optoelectronic devices operating at near-infrared wavelength. PMID- 27703179 TI - Mining gut microbiome oligopeptides by functional metaproteome display. AB - Pathogen infections, autoimmune diseases, and chronic inflammatory disorders are associated with systemic antibody responses from the host immune system. Disease specific antibodies can be important serum biomarkers, but the identification of antigens associated with specific immune reactions is challenging, in particular if complex communities of microorganisms are involved in the disease progression. Despite promising new diagnostic opportunities, the discovery of these serological markers becomes more difficult with increasing complexity of microbial communities. In the present work, we used a metagenomic M13 phage display approach to select immunogenic oligopeptides from the gut microbiome of transgenic mice suffering from chronic ileitis. We constructed three individual metaproteome phage display libraries with a library size of approximately 107 clones each. Using serum antibodies, we selected and validated three oligopeptides that induced specific antibody responses in the mouse model. This proof-of-concept study provides the first successful application of functional metaproteome display for the study of protein-protein interactions and the discovery of potential disease biomarkers.

PMID- 27703182 TI - Silver Nanowire-IZO-Conducting Polymer Hybrids for Flexible and Transparent Conductive Electrodes for Organic Light-Emitting Diodes. AB - Solution-processed silver nanowire (AgNW) has been considered as a promising material for next-generation flexible transparent conductive electrodes. However, despite the advantages of AgNWs, some of their intrinsic drawbacks, such as large surface roughness and poor interconnection between wires, limit their practical application in organic light-emitting diodes (OLEDs). Herein, we report a high performance AgNW-based hybrid electrode composed of indium-doped zinc oxide (IZO) and poly (3,4-ethylenediowythiophene):poly(styrenesulfonate) [PEDOT:PSS]. The IZO layer protects the underlying AgNWs from oxidation and corrosion and tightly fuses the wires together and to the substrate. The PEDOT:PSS effectively reduces surface roughness and increases the hybrid films' transmittance. The fabricated electrodes exhibited a low sheet resistance of 5.9 Omegasq-1 with high transmittance of 86% at 550 nm. The optical, electrical, and mechanical properties of the AgNW-based hybrid films were investigated in detail to determine the structure-property relations, and whether optical or electrical properties could be controlled with variation in each layer's thickness to satisfy different requirements for different applications. Flexible OLEDs (f OLEDs) were successfully fabricated on the hybrid electrodes to prove their applicability; their performance was even better than those on commercial indium doped tin oxide (ITO) electrodes. PMID- 27703183 TI - Erratum: Magnetic measurements with atomic-plane resolution. PMID- 27703184 TI - Elastic Scattering Spectroscopy (ESS): an Instrument-Concept for Dynamics of Complex (Bio-) Systems From Elastic Neutron Scattering. AB - A new type of neutron-scattering spectroscopy is presented that is designed specifically to measure dynamics in bio-systems that are difficult to obtain in any other way. The temporal information is largely model-free and is analogous to relaxation processes measured with dielectric spectroscopy, but provides additional spacial and geometric aspects of the underlying dynamics. Numerical simulations of the basic instrument design show the neutron beam can be highly focussed, giving efficiency gains that enable the use of small samples. Although we concentrate on continuous neutron sources, the extension to pulsed neutron sources is proposed, both requiring minimal data-treatment and being broadly analogous with dielectric spectroscopy, they will open the study of dynamics to new areas of biophysics. PMID- 27703185 TI - Epigraph: A Vaccine Design Tool Applied to an HIV Therapeutic Vaccine and a Pan Filovirus Vaccine. AB - Epigraph is an efficient graph-based algorithm for designing vaccine antigens to optimize potential T-cell epitope (PTE) coverage. Epigraph vaccine antigens are functionally similar to Mosaic vaccines, which have demonstrated effectiveness in preliminary HIV non-human primate studies. In contrast to the Mosaic algorithm, Epigraph is substantially faster, and in restricted cases, provides a mathematically optimal solution. Epigraph furthermore has new features that enable enhanced vaccine design flexibility. These features include the ability to exclude rare epitopes from a design, to optimize population coverage based on inexact epitope matches, and to apply the code to both aligned and unaligned input sequences. Epigraph was developed to provide practical design solutions for two outstanding vaccine problems. The first of these is a personalized approach to a therapeutic T-cell HIV vaccine that would provide antigens with an excellent match to an individual's infecting strain, intended to contain or clear a chronic infection. The second is a pan-filovirus vaccine, with the potential to protect against all known viruses in the Filoviradae family, including ebolaviruses. A web-based interface to run the Epigraph tool suite is available (http://www.hiv.lanl.gov/content/sequence/EPIGRAPH/epigraph.html). PMID- 27703187 TI - Polymer Nanodot-Hybridized Alkyl Silicon Oxide Nanostructures for Organic Memory Transistors with Outstanding High-Temperature Operation Stability. AB - Organic memory devices (OMDs) are becoming more important as a core component in flexible electronics era because of their huge potentials for ultrathin, lightweight and flexible plastic memory modules. In particular, transistor-type OMDs (TOMDs) have been gradually spotlighted due to their structural advantages possessing both memory and driving functions in single devices. Although a variety of TOMDs have been developed by introducing various materials, less attention has been paid to the stable operation at high temperatures. Here we demonstrate that the polymer nanodot-embedded alkyl silicon oxide (ASiO) hybrid materials, which are prepared by sol-gel and thermal cross-linking reactions between poly(4-vinylphenol) (PVP) and vinyltriethoxysilane, can deliver low voltage (1~5 V) TOMDs with outstanding operation stability (>4700 cycles) at high temperatures (150 degrees C). The efficient low-voltage memory function is enabled by the embedded PVP nanodots with particular lattice nanostructures, while the high thermal stability is achieved by the cross-linked ASiO network structures. PMID- 27703188 TI - The Impact of Li Grain Size on Coulombic Efficiency in Li Batteries. AB - One of the most promising means to increase the energy density of state-of-the art lithium Li-ion batteries is to replace the graphite anode with a Li metal anode. While the direct use of Li metal may be highly advantageous, at present its practical application is limited by issues related to dendrite growth and low Coulombic efficiency, CE. Here operando electrochemical scanning transmission electron microscopy (STEM) is used to directly image the deposition/stripping of Li at the anode-electrolyte interface in a Li-based battery. A non-aqueous electrolyte containing small amounts of H2O as an additive results in remarkably different deposition/stripping properties as compared to the "dry" electrolyte when operated under identical electrochemical conditions. The electrolyte with the additive deposits more Li during the first cycle, with the grain sizes of the Li deposits being significantly larger and more variable. The stripping of the Li upon discharge is also more complete, i.e., there is a higher cycling CE. This suggests that larger grain sizes are indicative of better performance by leading to more uniform Li deposition and an overall decrease in the formation of Li dendrites and side reactions with electrolyte components, thus potentially paving the way for the direct use of Li metal in battery technologies. PMID- 27703186 TI - Matrix factorization reveals aging-specific co-expression gene modules in the fat and muscle tissues in nonhuman primates. AB - Accurate identification of coherent transcriptional modules (subnetworks) in adipose and muscle tissues is important for revealing the related mechanisms and co-regulated pathways involved in the development of aging-related diseases. Here, we proposed a systematically computational approach, called ICEGM, to Identify the Co-Expression Gene Modules through a novel mathematical framework of Higher-Order Generalized Singular Value Decomposition (HO-GSVD). ICEGM was applied on the adipose, and heart and skeletal muscle tissues in old and young female African green vervet monkeys. The genes associated with the development of inflammation, cardiovascular and skeletal disorder diseases, and cancer were revealed by the ICEGM. Meanwhile, genes in the ICEGM modules were also enriched in the adipocytes, smooth muscle cells, cardiac myocytes, and immune cells. Comprehensive disease annotation and canonical pathway analysis indicated that immune cells, adipocytes, cardiomyocytes, and smooth muscle cells played a synergistic role in cardiac and physical functions in the aged monkeys by regulation of the biological processes associated with metabolism, inflammation, and atherosclerosis. In conclusion, the ICEGM provides an efficiently systematic framework for decoding the co-expression gene modules in multiple tissues. Analysis of genes in the ICEGM module yielded important insights on the cooperative role of multiple tissues in the development of diseases. PMID- 27703190 TI - Association of interleukin 16 gene polymorphisms and plasma IL16 level with osteosarcoma risk. AB - Interleukin (IL) 16 plays a key role in inflammatory diseases as well as in tumorigenesis of osteosarcoma (OS). The aim of this study was to investigate the association of IL16 polymorphisms and plasma IL16 level with OS risk in a Chinese population. We genotyped IL16 rs4778889, rs11556218, and rs4072111 in 358 patients with OS and 402 controls using a polymerase chain reaction-restriction fragment length polymorphism assay. Plasma IL16 level was measured by enzyme linked immunosorbent assay. Rs11556218 was associated with an increased risk of OS in heterozygote comparison (adjusted OR = 1.65, 95% CI, 1.23-2.21, P < 0.001), dominant model (adjusted OR = 1.66, 95% CI, 1.24-2.21, P < 0.001), and allele comparison (adjusted OR = 1.44, 95% CI, 1.14-1.81, P = 0.002). Moreover, rs11556218 TG/GG genotypes were associated with higher levels of IL16 as compared to TT genotype (P = 0.03). However, no significant association of rs4778889 and rs4072111 and OS was found. These findings suggest that rs11556218 TG/GG genotypes may be associated with increased susceptibility to OS, probably by increasing the production of IL16 level. PMID- 27703189 TI - Dissection of brassinosteroid-regulated proteins in rice embryos during germination by quantitative proteomics. AB - Brassinosteroids (BRs), essential plant-specific steroidal hormones, function in a wide spectrum of plant growth and development events, including seed germination. Rice is not only a monocotyledonous model plant but also one of the most important staple food crops of human beings. Rice seed germination is a decisive event for the next-generation of plant growth and successful seed germination is critical for rice yield. However, little is known about the molecular mechanisms on how BR modulates seed germination in rice. In the present study, we used isobaric tags for relative and absolute quantification (iTRAQ) based proteomic approach to study BR-regulated proteome during the early stage of seed germination. The results showed that more than 800 BR-responsive proteins were identified, including 88 reliable target proteins responsive to stimuli of both BR-deficiency and BR-insensitivity. Moreover, 90% of the 88 target proteins shared a similar expression change pattern. Gene ontology and string analysis indicated that ribosomal structural proteins, as well as proteins involved in protein biosynthesis and carbohydrate metabolisms were highly clustered. These findings not only enrich BR-regulated protein database in rice seeds, but also allow us to gain novel insights into the molecular mechanism of BR regulated seed germination. PMID- 27703191 TI - Measuring populations to improve vaccination coverage. AB - In low-income settings, vaccination campaigns supplement routine immunization but often fail to achieve coverage goals due to uncertainty about target population size and distribution. Accurate, updated estimates of target populations are rare but critical; short-term fluctuations can greatly impact population size and susceptibility. We use satellite imagery to quantify population fluctuations and the coverage achieved by a measles outbreak response vaccination campaign in urban Niger and compare campaign estimates to measurements from a post-campaign survey. Vaccine coverage was overestimated because the campaign underestimated resident numbers and seasonal migration further increased the target population. We combine satellite-derived measurements of fluctuations in population distribution with high-resolution measles case reports to develop a dynamic model that illustrates the potential improvement in vaccination campaign coverage if planners account for predictable population fluctuations. Satellite imagery can improve retrospective estimates of vaccination campaign impact and future campaign planning by synchronizing interventions with predictable population fluxes. PMID- 27703192 TI - GDF11 improves tubular regeneration after acute kidney injury in elderly mice. AB - The GDF11 expression pattern and its effect on organ regeneration after acute injury in the elderly population are highly controversial topics. In our study, GDF11/8 expression increased after kidney ischemia-reperfusion injury (IRI), and the relatively lower level of GDF11/8 in the kidneys of aged mice was associated with a loss of proliferative capacity and a decline in renal repair, compared to young mice. In vivo, GDF11 supplementation in aged mice increased vimentin and Pax2 expression in the kidneys as well as the percentage of 5-ethynyl-2' deoxyuridine (EdU)-positive proximal tubular epithelial cells. GDF11 improved the renal repair, recovery of renal function, and survival of elderly mice at 72 h after IRI. Moreover, the addition of recombinant GDF11 to primary renal epithelial cells increased proliferation, migration, and dedifferentiation by upregulating the ERK1/2 pathway in vitro. Our study indicates that GDF11/8 in the kidney decreases with age and that GDF11 can increase tubular cell dedifferentiation and proliferation as well as improve tubular regeneration after acute kidney injury (AKI) in old mice. PMID- 27703193 TI - Genes implicated in thiopurine-induced toxicity: Comparing TPMT enzyme activity with clinical phenotype and exome data in a paediatric IBD cohort. AB - The aim of our study was to assess the utility of next generation sequencing (NGS) for predicting toxicity and clinical response to thiopurine drugs in paediatric patients with inflammatory bowel disease. Exome data for 100 patients were assessed against biochemically measured TPMT enzyme activity, clinical response and adverse effects. The TPMT gene and a panel of 15 other genes implicated in thiopurine toxicity were analysed using a gene based statistical test (SKAT-O test). Nine patients out of 100 (Crohn's disease- 67, ulcerative colitis- 23 and IBDU-10) had known TPMT mutations associated with deficient enzyme activity. A novel and a highly pathogenic TPMT variant not detectable through standard genotyping, was identified through NGS in an individual intolerant to thiopurines. Of the 14 patients intolerant to thiopurines, NGS identified deleterious TPMT variants in 5 individuals whereas the biochemical test identified 8 individuals as intolerant (sensitivity 35.7% and 57.14%; specificity 93.75% and 50% respectively). SKAT-O test identified a significant association between MOCOS gene and TPMT activity (p = 0.0015), not previously reported. Although NGS has the ability to detect rare or novel variants not otherwise identified through standard genotyping, it demonstrates no clear advantage over the biochemical test in predicting toxicity in our modest cohort. PMID- 27703194 TI - Maternal Fructose Exposure Programs Metabolic Syndrome-Associated Bladder Overactivity in Young Adult Offspring. AB - Maternal fructose exposure (MFE) programs the development of metabolic syndrome (MetS) in young adult offspring. Epidemiological data indicate that MetS may increase the risks of overactive bladder (OAB) symptoms. However, it remains unknown whether MFE programs MetS-associated bladder dysfunction in adult offspring. Using Sprague-Dawley rats, we investigated the effects of MFE during pregnancy and lactation on developmental programming of MetS-associated bladder dysfunction. In addition, next generation sequencing technology was used to identify potential transcripts involved in the programmed bladder dysfunction in adult male offspring to MFE. We found that MFE programmed the MetS-associated OAB symptoms (i.e., an increase in micturition frequency and a shortened mean inter contractile interval) in young adult male offspring, alongside significant alterations in bladder transcripts, including Chrm2, Chrm3, P2rx1, Trpv4, and Vipr2 gene expression. At protein level, the expressions of M2-, M3-muscarinic and P2X1 receptor proteins were upregulated in the MFE bladder. Functionally, the carbachol-induced detrusor contractility was reduced in the MFE offspring. These data suggest that alterations in the bladder transcripts and impairment of the bladder cholinergic pathways may underlie the pathophysiology of programmed bladder dysfunction in adult offspring to MFE. PMID- 27703195 TI - Dual-responsive and Multi-functional Plasmonic Hydrogel Valves and Biomimetic Architectures Formed with Hydrogel and Gold Nanocolloids. AB - We present a straightforward approach with high moldability for producing dual responsive and multi-functional plasmonic hydrogel valves and biomimetic architectures that reversibly change volumes and colors in response to temperature and ion variations. Heating of a mixture of hybrid colloids (gold nanoparticles assembled on a hydrogel colloid) and hydrogel colloids rapidly induces (within 30 min) the formation of hydrogel architectures resembling mold shapes (cylinder, fish, butterfly). The biomimetic fish and butterfly display reversible changes in volumes and colors with variations of temperature and ionic conditions in aqueous solutions. The cylindrical plasmonic valves installed in flow tubes rapidly control water flow rate in on-off manner by responding to these stimuli. They also report these changes in terms of their colors. Therefore, the approach presented here might be helpful in developing new class of biomimetic and flow control systems where liquid conditions should be visually notified (e.g., glucose or ion concentration changes). PMID- 27703196 TI - Degradation of Redox-Sensitive Proteins including Peroxiredoxins and DJ-1 is Promoted by Oxidation-induced Conformational Changes and Ubiquitination. AB - Reactive oxygen species (ROS) are key molecules regulating various cellular processes. However, what the cellular targets of ROS are and how their functions are regulated is unclear. This study explored the cellular proteomic changes in response to oxidative stress using H2O2 in dose- and recovery time-dependent ways. We found discernible changes in 76 proteins appearing as 103 spots on 2D PAGE. Of these, Prxs, DJ-1, UCH-L3 and Rla0 are readily oxidized in response to mild H2O2 stress, and then degraded and active proteins are newly synthesized during recovery. In studies designed to understand the degradation process, multiple cellular modifications of redox-sensitive proteins were identified by peptide sequencing with nanoUPLC-ESI-q-TOF tandem mass spectrometry and the oxidative structural changes of Prx2 explored employing hydrogen/deuterium exchange-mass spectrometry (HDX-MS). We found that hydrogen/deuterium exchange rate increased in C-terminal region of oxidized Prx2, suggesting the exposure of this region to solvent under oxidation. We also found that Lys191 residue in this exposed C-terminal region of oxidized Prx2 is polyubiquitinated and the ubiquitinated Prx2 is readily degraded in proteasome and autophagy. These findings suggest that oxidation-induced ubiquitination and degradation can be a quality control mechanism of oxidized redox-sensitive proteins including Prxs and DJ-1.

Consequently it is often useful to understand how an attempt to influence a network will change its structure and consequently achieve other goals. We develop a framework for network modification that allows for arbitrary objective functions, types of modification (e.g. edge weight addition, edge weight removal, node removal, and covariate value change), and recovery mechanisms (i.e. how a network responds to interventions). The framework outlined in this paper helps both to situate the existing work on network interventions but also opens up many new possibilities for intervening in networks. In particular use two case studies to highlight the potential impact of empirically calibrating the objective function and network recovery mechanisms as well as showing how interventions beyond node removal can be optimised. First, we simulate an optimal removal of nodes from the Noordin terrorist network in order to reduce the expected number of attacks (based on empirically predicting the terrorist collaboration network from multiple types of network ties). Second, we simulate optimally strengthening ties within entrepreneurial ecosystems in six developing countries. In both cases we estimate ERGM models to simulate how a network will endogenously evolve after intervention.

AB - We present COMPASS, a COmputational Model to Predict the development of Alzheimer's diSease Spectrum, to model Alzheimer's disease (AD) progression. This was the best-performing method in recent crowdsourcing benchmark study, DREAM Alzheimer's Disease Big Data challenge to predict changes in Mini-Mental State Examination (MMSE) scores over 24-months using standardized data. In the present study, we conducted three additional analyses beyond the DREAM challenge question to improve the clinical contribution of our approach, including: (1) adding pre validated baseline cognitive composite scores of ADNI-MEM and ADNI-EF, (2) identifying subjects with significant declines in MMSE scores, and (3) incorporating SNPs of top 10 genes connected to APOE identified from functional relationship network. For (1) above, we significantly improved predictive accuracy, especially for the Mild Cognitive Impairment (MCI) group. For (2), we achieved an area under ROC of 0.814 in predicting significant MMSE decline: our model has 100% precision at 5% recall, and 91% accuracy at 10% recall. For (3), "genetic only" model has Pearson's correlation of 0.15 to predict progression in the MCI group. Even though addition of this limited genetic model to COMPASS did not improve prediction of progression of MCI group, the predictive ability of SNP information extended beyond well-known APOE allele. PMID- 27703199 TI - l-Ornithine affects peripheral clock gene expression in mice. AB - The peripheral circadian clock is entrained by factors in the external environment such as scheduled feeding, exercise, and mental and physical stresses. In addition, recent studies in mice demonstrated that some food components have the potential to control the peripheral circadian clock during scheduled feeding, although information about these components remains limited. l Ornithine is a type of non-protein amino acid that is present in foods and has been reported to have various physiological functions. In human trials, for example, l-ornithine intake improved a subjective index of sleep quality. Here we demonstrate, using an in vivo monitoring system, that repeated oral administration of l-ornithine at an early inactive period in mice induced a phase advance in the rhythm of PER2 expression. By contrast, l-ornithine administration to mouse embryonic fibroblasts did not affect the expression of PER2, indicating that l-ornithine indirectly alters the phase of PER2. l-Ornithine also increased plasma levels of insulin, glucose and glucagon-like peptide-1 alongside mPer2 expression, suggesting that it exerts its effects probably via insulin secretion. Collectively, these findings demonstrate that l-ornithine affects peripheral clock gene expression and may expand the possibilities of L-ornithine as a health food. PMID- 27703200 TI - Leukotriene B4 receptor type 2 protects against pneumolysin-dependent acute lung injury. AB - Although pneumococcal infection is a serious problem worldwide and has a high mortality rate, the molecular mechanisms underlying the lethality caused by pneumococcus remain elusive. Here, we show that BLT2, a G protein-coupled receptor for leukotriene B4 and 12(S)-hydroxyheptadecatrienoic acid (12-HHT), protects mice from lung injury caused by a pneumococcal toxin, pneumolysin (PLY). Intratracheal injection of PLY caused lethal acute lung injury (ALI) in BLT2 deficient mice, with evident vascular leakage and bronchoconstriction. Large amounts of cysteinyl leukotrienes (cysLTs), classically known as a slow reactive substance of anaphylaxis, were detected in PLY-treated lungs. PLY-dependent vascular leakage, bronchoconstriction, and death were markedly ameliorated by treatment with a CysLT1 receptor antagonist. Upon stimulation by PLY, mast cells produced cysLTs that activated CysLT1 expressed in vascular endothelial cells and bronchial smooth muscle cells, leading to lethal vascular leakage and bronchoconstriction. Treatment of mice with aspirin or loxoprofen inhibited the production of 12-HHT and increased the sensitivity toward PLY, which was also ameliorated by the CysLT1 antagonist. Thus, the present study identifies the molecular mechanism underlying PLY-dependent ALI and suggests the possible use of CysLT1 antagonists as a therapeutic tool to protect against ALI caused by pneumococcal infection. PMID- 27703202 TI - Inflammatory markers and clinical characteristics for predicting persistent positivity of interferon gamma release assay in dialysis population. AB - The interferon-gamma release assay (IGRA) is useful for diagnosing latent tuberculosis infection (LTBI), however the rate of negative conversion is high, especially in dialysis patients. Few studies have focused on predicting persistently positive patients who are at high risk of tuberculosis reactivation. We screened dialysis patients, and used QuantiFERON-TB Gold In-tube (QFT-GIT) to identify LTBI. Of the 157 participants who had initially positive QFT-GIT, 82 had persistently positivity and 75 had negative conversion. The persistently positive group were younger, more were current smokers, and had higher plasma level of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and QFT-GIT responses than the negative conversion group. Multivariate logistic regression for persistent positivity revealed that high plasma sTREM-1 and QFT-GIT response, young age and TB contact history were independent factors. Currently smoking had borderline significance. The area under the receiver operating characteristic curve using the multi-factor model was 0.878, higher than 0.821 by QFT-GIT response of 0.95 IU/ml. In conclusion, dialysis patients with persistent LTBI status may be associated with a young age, high plasma sTREM-1, strong QFT-GIT response, currently smoking, and TB contact history. If resources are limited, these five predictors can be used to prioritize QFT-GIT-positive dialysis patients for LTBI treatment. PMID- 27703203 TI - Unravelling the low-temperature metastable state in perovskite solar cells by noise spectroscopy. AB - The hybrid perovskite methylammonium lead iodide CH3NH3PbI3 recently revealed its potential for the manufacturing of low-cost and efficient photovoltaic cells. However, many questions remain unanswered regarding the physics of the charge carrier conduction. In this respect, it is known that two structural phase transitions, occurring at temperatures near 160 and 310 K, could profoundly change the electronic properties of the photovoltaic material, but, up to now, a clear experimental evidence has not been reported. In order to shed light on this topic, the low-temperature phase transition of perovskite solar cells has been thoroughly investigated by using electric noise spectroscopy. Here it is shown that the dynamics of fluctuations detect the existence of a metastable state in a crossover region between the room-temperature tetragonal and the low-temperature orthorhombic phases of the perovskite compound. Besides the presence of a noise peak at this transition, a saturation of the fluctuation amplitudes is observed induced by the external DC current or, equivalently, by light exposure. This noise saturation effect is independent on temperature, and may represent an important aspect to consider for a detailed explanation of the mechanisms of operation in perovskite solar cells. PMID- 27703201 TI - Rhein reversal of DNA hypermethylation-associated Klotho suppression ameliorates renal fibrosis in mice. AB - Renal fibrosis is the hallmark of chronic kidney diseases (CKD) and its development and progression are significantly affected by epigenetic modifications. Rhein, a plant-derived anthraquinone, displays strong anti fibrosis properties, but its protective mode of action remains incompletely understood. Here we explore the mechanism of Rhein anti-renal fibrosis by investigating its regulation of Klotho, a known renal anti-fibrotic protein whose suppression after renal injury reportedly involves aberrant DNA methylation. We report that Rhein is an impressive up-regulator of Klotho and it markedly reversed Klotho down-regulation in unilateral ureteral occlusion-induced fibrotic kidney. Further examinations revealed that Klotho loss in fibrotic kidney is associated with Klotho promoter hypermethylation due to aberrant methyltransferase 1 and 3a expressions. However, Rhein significantly corrected all these epigenetic alterations and subsequently alleviated pro-fibrotic protein expression and renal fibrosis, whereas Klotho knockdown via RNA interferences largely abrogated the anti-renal fibrotic effects of Rhein, suggesting that Rhein epigenetic reversal of Klotho loss represents a critical mode of action that confers Rhein's anti- renal fibrotic functions. Altogether our studies uncover a novel hypomethylating character of Rhein in preventing Klotho loss and renal fibrosis, and demonstrate the efficacy of Klotho-targeted epigenetic intervention in potential treatment of renal fibrosis-associated kidney diseases. PMID- 27703204 TI - Laser-assisted fabrication of single-layer flexible touch sensor. AB - Single-layer flexible touch sensor that is designed for the indium-tin-oxide (ITO)-free, bendable, durable, multi-sensible, and single layer transparent touch sensor was developed via a low-cost and one-step laser-induced fabrication technology. To this end, an entirely novel approach involving material, device structure, and even fabrication method was adopted. Conventional metal oxides based multilayer touch structure was substituted by the single layer structure composed of integrated silver wire networks of sensors and bezel interconnections. This structure is concurrently fabricated on a glass substitutive plastic film via the laser-induced fabrication method using the low cost organometallic/nanoparticle hybrid complex. In addition, this study addresses practical solutions to heterochromia and interference problem with a color display unit. As a result, a practical touch sensor is successfully demonstrated through resolving the heterochromia and interference problems with color display unit. This study could provide the breakthrough for early realization of wearable device. PMID- 27703205 TI - Effects of Resistance-Associated NS5A Mutations in Hepatitis C Virus on Viral Production and Susceptibility to Antiviral Reagents. AB - Direct-acting antivirals (DAAs) for hepatitis C virus (HCV) have potent anti-HCV effects but may provoke resistance-associated variants (RAVs). In this study, we assessed the characteristics of these RAVs and explored efficacious anti-HCV reagents using recombinant HCV with NS5A from a genotype 1b strain. We replaced the NS5A of JFH1 with that of Con1 (JFH1/5ACon1) and introduced known NS5A inhibitor resistance mutations (L31M, L31V, L31I and Y93H) individually or in combination. Susceptibilities against anti-HCV reagents were also investigated. RAVs with Y93H exhibited high extracellular core antigen levels and infectivity titers. Variants with any single mutation showed mild to moderate resistance against NS5A inhibitors, whereas variants with double mutations at both L31 and Y93 showed severe resistance. The variants with mutations exhibited similar levels of susceptibility to interferon (IFN)-alpha, IFN-lambda1, IFN-lambda3 and Ribavirin. Variants with the Y93H mutation were more sensitive to protease inhibitors compared with JFH1/5ACon1. In conclusion, the in vitro analysis indicated that the Y93H mutation enhanced infectious virus production, suggesting advantages in the propagation of RAVs with this mutation. However, these RAVs were susceptible to protease inhibitors. Thus, a therapeutic regimen that includes these reagents is a promising means to eradicate these RAVs. PMID- 27703206 TI - Two isoforms of TALDO1 generated by alternative translational initiation show differential nucleocytoplasmic distribution to regulate the global metabolic network. AB - Transaldolase 1 (TALDO1) is a rate-limiting enzyme involved in the pentose phosphate pathway, which is traditionally thought to occur in the cytoplasm. In this study, we found that the gene TALDO1 has two translational initiation sites, generating two isoforms that differ by the presence of the first 10 N-terminal amino acids. Notably, the long and short isoforms were differentially localised to the cell nucleus and cytoplasm, respectively. Pull-down and in vitro transport assays showed that the long isoform, unlike the short one, binds to importin alpha and is actively transported into the nucleus in an importin alpha/beta dependent manner, demonstrating that the 10 N-terminal amino acids are essential for its nuclear localisation. Additionally, we found that these two isoforms can form homo- and/or hetero-dimers with different localisation dynamics. A metabolite analysis revealed that the subcellular localisation of TALDO1 is not crucial for its activity in the pentose phosphate pathway. However, the expression of these two isoforms differentially affected the levels of various metabolites, including components of the tricarboxylic acid cycle, nucleotides, and sugars. These results demonstrate that the nucleocytoplasmic distribution of TALDO1, modulated via alternative translational initiation and dimer formation, plays an important role in a wide range of metabolic networks.

PMID- 27703207 TI - Novel population of small tumour-initiating stem cells in the ovaries of women with borderline ovarian cancer. AB - Small stem cells with diameters of up to 5 MUm previously isolated from adult human ovaries indicated pluripotency and germinal lineage, especially primordial germ cells, and developed into primitive oocyte-like cells in vitro. Here, we show that a comparable population of small stem cells can be found in the ovarian tissue of women with borderline ovarian cancer, which, in contrast to small stem cells in "healthy" ovaries, formed spontaneous tumour-like structures and expressed some markers related to pluripotency and germinal lineage. The gene expression profile of these small putative cancer stem cells differed from similar cells sorted from "healthy" ovaries by 132 upregulated and 97 downregulated genes, including some important forkhead box and homeobox genes related to transcription regulation, developmental processes, embryogenesis, and ovarian cancer. These putative cancer stem cells are suggested to be a novel population of ovarian tumour-initiating cells in humans. PMID- 27703209 TI - A novel exopolysaccharide elicitor from endophytic fungus Gilmaniella sp. AL12 on volatile oils accumulation in Atractylodes lancea. AB - Endophytes and plants can establish specific long-term symbiosis through the accumulation of secondary metabolites. Previous studies have shown that the endophytic fungus Gilmaniella sp. AL12 can stimulate Atractylodes lancea to produce volatile oils. The purpose of this report is to investigate key factors involved in the stimulation of A. lancea by AL12 and reveal the mechanism. We identified the active component from AL12 as an extracellular mannan with a polymerization degree of 26-42. Differential membrane proteomics of A. lancea was performed by 2D electrophoresis. The results showed that there were significant differences in the expression of 83 proteins. Based on these results, we conclude that AL12 secreted mannan contributes to the antagonistic balance seen in interactions between AL12 and A. lancea. One portion of the mannan was degraded to mannose for hexokinase activation, promoting photosynthesis and energy metabolism, with a potential metabolic fluxes flowing towards terpenoid biosynthesis. The other portion of the mannan directly enhanced autoimmunity of A. lancea through G protein-mediated signal transduction and the mannan-binding lectin pathway. Volatile oil accumulation was ultimately promoted in subsequent defense reactions. This study provides a new perspective on the regulation of secondary metabolites by endophytic fungal elicitors in medicinal plants. PMID- 27703210 TI - Preparation of cross-linked hen-egg white lysozyme crystals free of cracks. AB - Cross-linked protein crystals (CLPCs) are very useful materials in applications such as biosensors, catalysis, and X-ray crystallography. Hence, preparation of CLPCs is an important research direction. During the preparation of CLPCs, an often encountered problem is that cracks may appear in the crystals, which may finally lead to shattering of the crystals into small pieces and cause problem in practical applications. To avoid cross-link induced cracking, it is necessary to study the cracking phenomenon in the preparation process. In this paper, we present an investigation on how to avoid cracking during preparation of CLPCs. An orthogonal experiment was designed to study the phenomenon of cross-link induced cracking of hen-egg white lysozyme (HEWL) crystals against five parameters (temperature, solution pH, crystal growth time, glutaraldehyde concentration, and cross-linking time). The experimental results showed that, the solution pH and crystal growth time can significantly affect cross-link induced cracking. The possible mechanism was studied, and optimized conditions for obtaining crack-free CLPCs were obtained and experimentally verified. PMID- 27703212 TI - Construction of CuS/Au Heterostructure through a Simple Photoreduction Route for Enhanced Electrochemical Hydrogen Evolution and Photocatalysis. AB - An efficient Hydrogen evolution catalyst has been developed by decorating Au nanoparticle on the surface of CuS nanostructure following a green and environmental friendly approach. CuS nanostructure is synthesized through a simple wet-chemical route. CuS being a visible light photocatalyst is introduced to function as an efficient reducing agent. Photogenerated electron is used to reduce Au(III) on the surface of CuS to prepare CuS/Au heterostructure. The as obtained heterostructure shows excellent performance in electrochemical H2 evolution reaction with promising durability in acidic condition, which could work as an efficient alternative for novel metals. The most efficient CuS-Au heterostructure can generate 10 mA/cm2 current density upon application of 0.179 V vs. RHE. CuS-Au heterostructure can also perform as an efficient photocatalyst for the degradation of organic pollutant. This dual nature of CuS and CuS/Au both in electrocatalysis and photocatalysis has been unveiled in this study. PMID- 27703211 TI - Fractionated radiation exposure amplifies the radioresistant nature of prostate cancer cells. AB - The risk of recurrence following radiation therapy remains high for a significant number of prostate cancer patients. The development of in vitro isogenic models of radioresistance through exposure to fractionated radiation is an increasingly used approach to investigate the mechanisms of radioresistance in cancer cells and help guide improvements in radiotherapy standards. We treated 22Rv1 prostate cancer cells with fractionated 2 Gy radiation to a cumulative total dose of 60 Gy. This process selected for 22Rv1-cells with increased clonogenic survival following subsequent radiation exposure but increased sensitivity to Docetaxel. This RR-22Rv1 cell line was enriched in S-phase cells, less susceptible to DNA damage, radiation-induced apoptosis and acquired enhanced migration potential, when compared to wild type and aged matched control 22Rv1 cells. The selection of radioresistant cancer cells during fractionated radiation therapy may have implications in the development and administration of future targeted therapy in conjunction with radiation therapy. PMID- 27703213 TI - Bone marrow mesenchymal stem cells attenuate 2,5-hexanedione-induced neuronal apoptosis through a NGF/AKT-dependent pathway. AB - Growing evidence suggests that the increased neuronal apoptosis is involved in n hexane-induced neuropathy. We have recently reported that bone marrow-mesenchymal stem cells-derived conditioned medium (BMSC-CM) attenuated 2,5-hexanedione (HD, the active metabolite of n-hexane)-induced apoptosis in PC12 cells. Here, we explored the anti-apoptotic efficacy of BMSC in vivo. HD-treated rats received BMSC by tail vein injection 5 weeks after HD intoxication. We found that in grafted rats, BMSC significantly attenuated HD-induced neuronal apoptosis in the spinal cord, which was associated with elevation of nerve growth factor (NGF). Neutralization of NGF in BMSC-CM blocked the protection against HD-induced apoptosis in VSC4.1 cells, suggesting that NGF is essential for BMSC-afforded anti-apoptosis. Mechanistically, we found that the decreased activation of Akt induced by HD was significantly recovered in the spinal cord by BMSC and in VSC4.1 cells by BMSC-CM in a TrkA-dependent manner, leading to dissociation of Bad/Bcl-xL complex in mitochondria and release of anti-apoptotic Bcl-xL. The importance of Akt was further corroborated by showing the reduced anti-apoptotic potency of BMSC in HD-intoxicated VSC4.1 cells in the presence of Akt inhibitor, MK-2206. Thus, our findings show that BMSC attenuated HD-induced neuronal apoptosis in vivo through a NGF/Akt-dependent manner, providing a novel solution against n-hexane-induced neurotoxicity. PMID- 27703214 TI - Lateralization of gene expression in the honeybee brain during olfactory learning. AB - In the last decade, it has been demonstrated that brain functional asymmetry occurs not only in vertebrates but also in invertebrates. However, the mechanisms underlying functional asymmetry remain unclear. In the present study, we trained honeybees of the same parentage and age, on the proboscis extension reflex (PER) paradigm with only one antenna in use. The comparisons of gene expression between the left and right hemispheres were carried out using high throughput sequencing. Our research revealed that gene expression in the honeybee brain is also asymmetric, with more genes having higher expression in the right hemisphere than the left hemisphere. Our studies show that during olfactory learning, the left hemisphere is more responsible for long term memory and the right hemisphere is more responsible for the learning and short term memory. PMID- 27703215 TI - Forest biomass carbon stocks and variation in Tibet's carbon-dense forests from 2001 to 2050. AB - Tibet's forests, in contrast to China's other forests, are characterized by primary forests, high carbon (C) density and less anthropogenic disturbance, and they function as an important carbon pool in China. Using the biomass C density data from 413 forest inventory sites and a spatial forest age map, we developed an allometric equation for the forest biomass C density and forest age to assess the spatial biomass C stocks and variation in Tibet's forests from 2001 to 2050. The results indicated that the forest biomass C stock would increase from 831.1 Tg C in 2001 to 969.4 Tg C in 2050, with a net C gain of 3.6 Tg C yr-1 between 2001 and 2010 and a decrease of 1.9 Tg C yr-1 between 2040 and 2050. Carbon tends to allocate more in the roots of fir forests and less in the roots of spruce and pine forests with increasing stand age. The increase of the biomass carbon pool does not promote significant augmentation of the soil carbon pool. Our findings suggest that Tibet's mature forests will remain a persistent C sink until 2050. However, afforestation or reforestation, especially with the larger carbon sink potential forest types, such as fir and spruce, should be carried out to maintain the high C sink capacity. PMID- 27703217 TI - Re-evaluation of all-plastic organic dye laser with DFB structure fabricated using photoresists. AB - Organic solid-state lasers (OSSLs) with distributed feedback structures can detect nanoscale materials and therefore offer an attractive sensing platform for biological and medical applications. Here we investigate the lasing characteristics, i.e., the threshold and slope efficiency, as a function of the grating depth in OSSL devices with distributed feedback (DFB) structure fabricated using photoresists. Two types of photoresists were used for the DFB structures: a negative photoresist, SU-8 2002, and a positive photoresist, ma-P 1275. The DFB structure was fabricated using a Lloyd-mirror configuration. The active layer was a rhodamine 6G-doped cellulose acetate waveguide. The threshold for the first order mode (m = 1) was lower than that for the second and third order modes (m = 2, and 3). A low threshold of 27 MUJ cm-2 pulse-1 (58 nJ) was obtained using SU-8 2002, with m = 1. The slope efficiency was evaluated as a function of grating depth for each mode and increased as the grating depth increased. PMID- 27703218 TI - Generation of Scratches and Their Effects on Laser Damage Performance of Silica Glass. AB - Scratches are deleterious to precision optics because they can obscure and modulate incident laser light, which will increase the probability of damage to optical components. We here imitated the generation of brittle and ductile scratches during polishing process and endeavored to find out the possible influence of scratches on laser induced damage. Brittle scratches can be induced by spiking large sized abrasives and small abrasives may only generate ductile scratches. Both surface roughness and transmittivity are degraded due to the appearance of brittle scratches while ductile scratches make little difference to surface roughness and transmittance. However, ductile and brittle scratches greatly increase the density of damage about one order of magnitude relative to unscratched surface. In particular, ductile scratches also play an unignorable role in laser induced damage, which is different from previous knowledge. Furthermore, ZrO2 and Al2O3 polished surfaces appear to perform best in terms of damage density. PMID- 27703216 TI - Neocortical grey matter distribution underlying voluntary, flexible vocalizations in chimpanzees. AB - Vocal learning is a key property of spoken language, which might also be present in nonhuman primate species, such as chimpanzees (Pan troglodytes), to a limited degree. While understanding the origins of vocal learning in the primate brain may help shed light on the evolution of speech and language, little is still known regarding the neurobiological correlates of vocal flexibility in nonhuman primates. The current study used voxel-based morphometry (VBM) to assess whether the cerebral cortex of captive chimpanzees that learned to voluntarily produce sounds to attract the attention of a human experimenter (attention-getting sounds) differs in grey matter distribution compared to chimpanzees that do not exhibit this behavior. It was found that chimpanzees that produce attention getting sounds were characterized by increased grey matter in the ventrolateral prefrontal and dorsal premotor cortices. These findings suggest that the evolution of the capacity to flexibly modulate vocal output may be associated with reorganization of regions for motor control, including orofacial movements, in the primate brain. PMID- 27703220 TI - Nano-volcanic Eruption of Silver. AB - Silver (Ag) is one of the seven metals of antiquity and an important engineering material in the electronic, medical, and chemical industries because of its unique noble and catalytic properties. Ag thin films are extensively used in modern electronics primarily because of their oxidation-resistance. Here we report a novel phenomenon of Ag nano-volcanic eruption that is caused by interactions between Ag and oxygen (O). It involves grain boundary liquation, the ejection of transient Ag-O fluids through grain boundaries, and the decomposition of Ag-O fluids into O2 gas and suspended Ag and Ag2O clusters. Subsequent coating with re-deposited Ag-O and the de-alloying of O yield a conformal amorphous Ag coating. Patterned Ag hillock arrays and direct Ag-to-Ag bonding can be formed by the homogenous crystallization of amorphous coatings. The Ag "nano-volcanic eruption" mechanism is elaborated, shedding light on a new mechanism of hillock formation and new applications of amorphous Ag coatings. PMID- 27703219 TI - Antiangiogenic therapy using endostatin increases the number of ALDH+ lung cancer stem cells by generating intratumor hypoxia. AB - Antiangiogenic therapy is becoming a promising option for cancer treatment. However, many investigations have recently indicated that these therapies may have limited efficacy, and the cancers in most patients eventually develop resistance to these therapies. There is considerable recently acquired evidence for an association of such resistance with cancer stem-like cells (CSLCs). Here, we used xenograft tumor murine models to further suggest that antiangiogenic agents actually increase the invasive and metastatic properties of lung cancer cells. In our experiments with murine lung cancer xenografts, we found that the antiangiogenic agent endostatin increased the population of ALDH+ cells, and did so by generating intratumoral hypoxia in the xenografts. We further showed endostatin to cause an increase in the CSLC population by accelerating the generation of tumor hypoxia and by recruiting TAMs, MDSCs and Treg cells, which are inflammatory and immunosuppressive cells and which can secrete cytokines and growth factors such as IL-6, EGF, and TGF-beta into the tumor microenvironment. All these factors are related with increased CSLC population in tumors. These results imply that improving the clinical efficacy of antiangiogenic treatments will require the concurrent use of CSLC-targeting agents. PMID- 27703221 TI - The Principles of Ligand Specificity on beta-2-adrenergic receptor. AB - G protein-coupled receptors are recognized as one of the largest families of membrane proteins. Despite sharing a characteristic seven-transmembrane topology, G protein-coupled receptors regulate a wide range of cellular signaling pathways in response to various physical and chemical stimuli, and prevail as an important target for drug discovery. Notably, the recent progress in crystallographic methods led to a breakthrough in elucidating the structures of membrane proteins. The structures of beta2-adrenergic receptor bound with a variety of ligands provide atomic details of the binding modes of agonists, antagonists and inverse agonists. In this study, we selected four representative molecules from each functional class of ligands and investigated their impacts on beta2-adrenergic receptor through a total of 12 * 100 ns molecular dynamics simulations. From the obtained trajectories, we generated molecular fingerprints exemplifying propensities of protein-ligand interactions. For each functional class of compounds, we characterized and compared the fluctuation of the protein backbone, the volumes in the intracellular pockets, the water densities in the receptors, the domain interaction networks as well as the movements of transmembrane helices. We discovered that each class of ligands exhibits a distinct mode of interactions with mainly TM5 and TM6, altering the shape and eventually the state of the receptor. Our findings provide insightful prospective into GPCR targeted structure-based drug discoveries. PMID- 27703222 TI - Large linear magnetoresistance in heavily-doped Nb:SrTiO3 epitaxial thin films. AB - Interaction between electrons has long been a focused topic in condensed-matter physics since it has led to the discoveries of astonishing phenomena, for example, high-Tc superconductivity and colossal magnetoresistance (CMR) in strongly-correlated materials. In the study of strongly-correlated perovskite oxides, Nb-doped SrTiO3 (Nb:SrTiO3) has been a workhorse not only as a conducting substrate, but also as a host possessing high carrier mobility. In this work, we report the observations of large linear magnetoresistance (LMR) and the metal-to insulator transition (MIT) induced by magnetic field in heavily-doped Nb:STO (SrNb0.2Ti0.8O3) epitaxial thin films. These phenomena are associated with the interplay between the large classical MR due to high carrier mobility and the electronic localization effect due to strong spin-orbit coupling, implying that heavily Nb-doped Sr(Nb0.2Ti0.8)O3 is promising for the application in spintronic devices. PMID- 27703223 TI - Directional and monochromatic thermal emitter from epsilon-near-zero conditions in semiconductor hyperbolic metamaterials. AB - The development of novel thermal sources that control the emission spectrum and the angular emission pattern is of fundamental importance. In this paper, we investigate the thermal emission properties of semiconductor hyperbolic metamaterials (SHMs). Our structure does not require the use of any periodic corrugation to provide monochromatic and directional emission properties. We show that these properties arise because of epsilon-near-zero conditions in SHMs. The thermal emission is dominated by the epsilon-near-zero effect in the doped quantum wells composing the SHM. Furthermore, different properties are observed for s and p polarizations, following the characteristics of the strong anisotropy of hyperbolic metamaterials. PMID- 27703226 TI - Hybrid boron nitride-natural fiber composites for enhanced thermal conductivity. AB - Thermal conductivity was dramatically increased after adding natural fiber into hexagonal boron nitride (hBN)/epoxy composites. Although natural fiber does not show high-thermal conductivity itself, this study found that the synergy of natural fiber with hBN could significantly improve thermal conductivity, compared with that solely using hBN. A design of mixtures approach using constant fibers with increasing volume fractions of hBN was examined and compared. The thermal conductivity of the composite containing 43.6% hBN, 26.3% kenaf fiber and 30.1% epoxy reached 6.418 W m-1 K-1, which was 72.3% higher than that (3.600 W m-1 K-1) of the 69.0% hBN and 31.0% epoxy composite. Using the scanning electron microscope (SEM) and micro computed tomography (micro-CT), it was observed that the hBN powders were well distributed and ordered on the fiber surfaces enhancing the ceramic filler's interconnection, which may be the reason for the increase in thermal conductivity. Additionally, the results from mechanical and dynamic mechanical tests showed that performances dramatically improved after adding kenaf fibers into the hBN/epoxy composite, potentially benefiting the composite's use as an engineered material.

AB - Gallic acid, a type of phenolic acid, has been shown to have beneficial effects in inflammation, vascular calcification, and metabolic diseases. The present study was aimed at determining the effect and regulatory mechanism of gallic acid in cardiac hypertrophy and fibrosis. Cardiac hypertrophy was induced by isoproterenol (ISP) in mice and primary neonatal cardiomyocytes. Gallic acid pretreatment attenuated concentric cardiac hypertrophy. It downregulated the expression of atrial natriuretic peptide, brain natriuretic peptide, and beta myosin heavy chain in vivo and in vitro. Moreover, it prevented interstitial collagen deposition and expression of fibrosis-associated genes. Upregulation of collagen type I by Smad3 overexpression was observed in cardiac myoblast H9c2 cells but not in cardiac fibroblasts. Gallic acid reduced the DNA binding activity of phosphorylated Smad3 in Smad binding sites of collagen type I promoter in rat cardiac fibroblasts. Furthermore, it decreased the ISP-induced phosphorylation of c-Jun N-terminal kinase (JNK) and extracellular signal regulated kinase (ERK) protein in mice. JNK2 overexpression reduced collagen type I and Smad3 expression as well as GATA4 expression in H9c2 cells and cardiac fibroblasts. Gallic acid might be a novel therapeutic agent for the prevention of cardiac hypertrophy and fibrosis by regulating the JNK2 and Smad3 signaling pathway.

AB - Schizophrenia has been characterized by an impaired mentalizing. It has been suggested that distinguishing implicit from explicit processes is crucial in social cognition, and only the latter might be affected in schizophrenia. Two other questions remain open: (1) Is schizophrenia characterized by an hypo- or hyper attribution of intentions? (2) Is it characterized by a deficit in the attribution of intention or of contingency? To test these three questions, spontaneous mentalizing was tested in 29 individuals with schizophrenia and 29 control subjects using the Frith-Happe animations, while eye movements were recorded. Explicit mentalizing was measured from participants' verbal descriptions and was contrasted with implicit mentalizing measured through eye tracking. As a group, patients made less accurate and less intentional descriptions of the goal-directed and theory of mind animations. No group differences were found in the attribution of contingency. Eye tracking results revealed that patients and controls showed a similar modulation of eye movements in response to the mental states displayed in the Frith-Happe animations. To conclude, in this paradigm, participants with schizophrenia showed a dissociation between explicit and implicit mentalizing, with a decrease in the explicit attribution of intentions, whereas their eye movements suggested a preserved implicit perception of intentions.

AB - Antennae are among the most elaborate sensory organs in adult flies, and they provide rich information for phylogenic studies. The antennae of five out of eight species of Gasterophilus Leach (G. haemorrhoidalis (Linnaeus), G. intestinalis (De Geer), G. nasalis (Linnaeus), G. nigricornis (Loew) and G. pecorum (Fabricius)), were examined using scanning electron microscopy. The general morphology, including distribution, type, size, and ultrastructure of antennal sensilla were presented, and the definition of auriculate sensilla and sensory pits were updated and clarified. Eighteen antennal characters were selected to construct the first species-level phylogeny of this genus. The monophyly of Gasterophilus was supported by the presence of coeloconic sensilla III on the antennal arista. The species-level cladogram showed G. pecorum branching off at the base, and the remaining species forming the topology (G. intestinalis+ (G. haemorrhoidalis+ (G. nasalis+ G. nigricornis))). Our research shows the importance of the antennal ultrastructure as a reliable source for phylogenetic analysis. PMID- 27703230 TI - Erosion protection conferred by whole human saliva, dialysed saliva, and artificial saliva. AB - During dental erosion, tooth minerals are dissolved, leading to a softening of the surface and consequently to irreversible surface loss. Components from human saliva form a pellicle on the tooth surface, providing some protection against erosion. To assess the effect of different components and compositions of saliva on the protective potential of the pellicle against enamel erosion, we prepared four different kinds of saliva: human whole stimulated saliva (HS), artificial saliva containing only ions (AS), human saliva dialysed against artificial saliva, containing salivary proteins and ions (HS/AS), and human saliva dialysed against deionised water, containing only salivary proteins but no ions (HS/DW). Enamel specimens underwent four cycles of immersion in either HS, AS, HS/AS, HS/DW, or a humid chamber (Ctrl), followed by erosion with citric acid. During the cycling process, the surface hardness and the calcium released from the surface of the specimens were measured. The different kinds of saliva provided different levels of protection, HS/DW exhibiting significantly better protection than all the other groups (p < 0.0001). Different components of saliva, therefore, have different effects on the protective properties of the pellicle and the right proportions of these components in saliva are critical for the ability to form a protective pellicle. PMID- 27703231 TI - OAHG: an integrated resource for annotating human genes with multi-level ontologies. AB - OAHG, an integrated resource, aims to establish a comprehensive functional annotation resource for human protein-coding genes (PCGs), miRNAs, and lncRNAs by multi-level ontologies involving Gene Ontology (GO), Disease Ontology (DO), and Human Phenotype Ontology (HPO). Many previous studies have focused on inferring putative properties and biological functions of PCGs and non-coding RNA genes from different perspectives. During the past several decades, a few of databases have been designed to annotate the functions of PCGs, miRNAs, and lncRNAs, respectively. A part of functional descriptions in these databases were mapped to standardize terminologies, such as GO, which could be helpful to do further analysis. Despite these developments, there is no comprehensive resource recording the function of these three important types of genes. The current version of OAHG, release 1.0 (Jun 2016), integrates three ontologies involving GO, DO, and HPO, six gene functional databases and two interaction databases. Currently, OAHG contains 1,434,694 entries involving 16,929 PCGs, 637 miRNAs, 193 lncRNAs, and 24,894 terms of ontologies. During the performance evaluation, OAHG shows the consistencies with existing gene interactions and the structure of ontology. For example, terms with more similar structure could be associated with more associated genes (Pearson correlation gamma2 = 0.2428, p < 2.2e-16). PMID- 27703232 TI - Integrated analysis of microRNA and mRNA expression profiles highlights the complex and dynamic behavior of toosendanin-induced liver injury in mice. AB - Triterpenoid Toosendanin (TSN) exhibits a plenty of pharmacological effects in human and great values in agriculture. However, the hepatotoxicity caused by TSN or Melia-family plants containing TSN used in traditional Chinese medicine has been reported, and the mechanisms of TSN-induced liver injury (TILI) still remain largely unknown. In this study, the dose- and time-dependent effects of TSN on mice liver were investigated by an integrated microRNA-mRNA approach as well as the general toxicological assessments. As the results, the dose- and time dependent liver injury and alterations in global microRNA and mRNA expressions were detected. Particularly, 9-days 80 mg/kg TSN exposure caused most serious liver injury in mice, and the hepatic adaptation to TILI was unexpectedly observed after 21-days 80 mg/kg TSN administration. Based on the pathway analysis of the intersections between predicted targets of differentially expressed microRNAs and differentially expressed mRNAs at three time points, it revealed that TILI may be caused by glutathione depletion, mitochondrial dysfunction and lipid dysmetabolism, ultimately leading to hepatocytes necrosis in liver, while liver regeneration may play an important role in the hepatic adaptation to TILI. Our results demonstrated that the integrated microRNA-mRNA approach could provide new insight into the complex and dynamic behavior of TILI. PMID- 27703234 TI - A comprehensive insight into functional profiles of free-living microbial community responses to a toxic Akashiwo sanguinea bloom. AB - Phytoplankton blooms are a worldwide problem and can greatly affect ecological processes in aquatic systems, but its impacts on the functional potential of microbial communities are limited. In this study, a high-throughput microarray based technology (GeoChip) was used to profile the functional potential of free living microbes from the Xiamen Sea Area in response to a 2011 Akashiwo sanguinea bloom. The bloom altered the overall community functional structure. Genes that were significantly (p < 0.05) increased during the bloom included carbon degradation genes and genes involved in nitrogen (N) and/or phosphorus (P) limitation stress. Such significantly changed genes were well explained by chosen environmental factors (COD, nitrite-N, nitrate-N, dissolved inorganic phosphorus, chlorophyll-a and algal density). Overall results suggested that this bloom might enhance the microbial converting of nitrate to N2 and ammonia nitrogen, decrease P removal from seawater, activate the glyoxylate cycle, and reduce infection activity of bacteriophage. This study presents new information on the relationship of algae to other microbes in aquatic systems, and provides new insights into our understanding of ecological impacts of phytoplankton blooms. PMID- 27703233 TI - Biomimetic carriers mimicking leukocyte plasma membrane to increase tumor vasculature permeability. AB - Recent advances in the field of nanomedicine have demonstrated that biomimicry can further improve targeting properties of current nanotechnologies while simultaneously enable carriers with a biological identity to better interact with the biological environment. Immune cells for example employ membrane proteins to target inflamed vasculature, locally increase vascular permeability, and extravasate across inflamed endothelium. Inspired by the physiology of immune cells, we recently developed a procedure to transfer leukocyte membranes onto nanoporous silicon particles (NPS), yielding Leukolike Vectors (LLV). LLV are composed of a surface coating containing multiple receptors that are critical in the cross-talk with the endothelium, mediating cellular accumulation in the tumor microenvironment while decreasing vascular barrier function. We previously demonstrated that lymphocyte function-associated antigen (LFA-1) transferred onto LLV was able to trigger the clustering of intercellular adhesion molecule 1 (ICAM 1) on endothelial cells. Herein, we provide a more comprehensive analysis of the working mechanism of LLV in vitro in activating this pathway and in vivo in enhancing vascular permeability. Our results suggest the biological activity of the leukocyte membrane can be retained upon transplant onto NPS and is critical in providing the particles with complex biological functions towards tumor vasculature. PMID- 27703235 TI - Two-dimensional symbiotic solitons and vortices in binary condensates with attractive cross-species interaction. AB - We consider a two-dimensional (2D) two-component spinor system with cubic attraction between the components and intra-species self-repulsion, which may be realized in atomic Bose-Einstein condensates, as well as in a quasi-equilibrium condensate of microcavity polaritons. Including a 2D spatially periodic potential, which is necessary for the stabilization of the system against the critical collapse, we use detailed numerical calculations and an analytical variational approximation (VA) to predict the existence and stability of several types of 2D symbiotic solitons in the spinor system. Stability ranges are found for symmetric and asymmetric symbiotic fundamental solitons and vortices, including hidden-vorticity (HV) modes, with opposite vorticities in the two components. The VA produces exceptionally accurate predictions for the fundamental solitons and vortices. The fundamental solitons, both symmetric and asymmetric ones, are completely stable, in either case when they exist as gap solitons or regular ones. The symmetric and asymmetric vortices are stable if the inter-component attraction is stronger than the intra-species repulsion, while the HV modes have their stability region in the opposite case.

PMID- 27703236 TI - Nematodes join the family of chondroitin sulfate-synthesizing organisms: Identification of an active chondroitin sulfotransferase in Caenorhabditis elegans. AB - Proteoglycans are proteins that carry sulfated glycosaminoglycans (GAGs). They help form and maintain morphogen gradients, guiding cell migration and differentiation during animal development. While no sulfated GAGs have been found in marine sponges, chondroitin sulfate (CS) and heparan sulfate (HS) have been identified in Cnidarians, Lophotrocozoans and Ecdysozoans. The general view that nematodes such as Caenorhabditis elegans, which belong to Ecdysozoa, produce HS but only chondroitin without sulfation has therefore been puzzling. We have analyzed GAGs in C. elegans using reversed-phase ion-pairing HPLC, mass spectrometry and immunohistochemistry. Our analyses included wild type C. elegans but also a mutant lacking two HS sulfotransferases (hst-6 hst-2), as we suspected that the altered HS structure could boost CS sulfation. We could indeed detect sulfated CS in both wild type and mutant nematodes. While 4-O-sulfation of galactosamine dominated, we also detected 6-O-sulfated galactosamine residues. Finally, we identified the product of the gene C41C4.1 as a C. elegans CS sulfotransferase and renamed it chst-1 (CarboHydrate SulfoTransferase) based on loss of CS-4-O-sulfation in a C41C4.1 mutant and in vitro sulfotransferase activity of recombinant C41C4.1 protein. We conclude that C. elegans indeed manufactures CS, making this widely used nematode an interesting model for developmental studies involving CS.

AB - Super-resolution fluorescence microscopy revolutionizes cell biology research and provides novel insights on how proteins are organized at the nanoscale and in the cellular context. In order to extract a maximum of information, specialized tools for image analysis are necessary. Here, we introduce the LocAlization Microscopy Analyzer (LAMA), a comprehensive software tool that extracts quantitative information from single-molecule super-resolution imaging data. LAMA allows characterizing cellular structures by their size, shape, intensity, distribution, as well as the degree of colocalization with other structures. LAMA is freely available, platform-independent and designed to provide direct access to individual analysis of super-resolution data. PMID- 27703241 TI - Gene expression: Reading protein acetylation.

AB - The malaria vaccine BK-SE36 is a recombinant protein (SE36) based on the Honduras 1 serine repeat antigen-5 of Plasmodium falciparum, adsorbed to aluminium hydroxide gel. The phase Ib trial in Uganda demonstrated the safety and immunogenicity of BK-SE36. Ancillary analysis in the follow-up study of 6-20 year old volunteers suggest significant differences in time to first episodes of clinical malaria in vaccinees compared to placebo/control group. Here, we aimed to get further insights into the association of anti-SE36 antibody titres and natural P. falciparum infection. Children who received BK-SE36 and whose antibody titres against SE36 increased by >=1.92-fold after vaccination were categorised as responders. Most responders did not have or only had a single episode of natural P. falciparum infection. Notably, responders who did not experience infection had relatively high anti-SE36 antibody titres post-second vaccination compared to those who were infected. The anti-SE36 antibody titres of the responders who experienced malaria were boosted after infection and they had lower risk of reinfection. These findings show that anti-SE36 antibody titres induced by BK-SE36 vaccination offered protection against malaria. The vaccine is now being evaluated in a phase Ib trial in children less than 5 years old. PMID- 27703242 TI - Origins of mass spectrometry-based proteomics. PMID- 27703239 TI - Mechanistic evaluation and transcriptional signature of a glutathione S transferase omega 1 inhibitor. AB - Glutathione S-transferase omega 1 (GSTO1) is an atypical GST isoform that is overexpressed in several cancers and has been implicated in drug resistance. Currently, no small-molecule drug targeting GSTO1 is under clinical development. Here we show that silencing of GSTO1 with siRNA significantly impairs cancer cell viability, validating GSTO1 as a potential new target in oncology. We report on the development and characterization of a series of chloroacetamide-containing potent GSTO1 inhibitors. Co-crystal structures of GSTO1 with our inhibitors demonstrate covalent binding to the active site cysteine. These potent GSTO1 inhibitors suppress cancer cell growth, enhance the cytotoxic effects of cisplatin and inhibit tumour growth in colon cancer models as single agent. Bru seq-based transcription profiling unravelled novel roles for GSTO1 in cholesterol metabolism, oxidative and endoplasmic stress responses, cytoskeleton and cell migration. Our findings demonstrate the therapeutic utility of GSTO1 inhibitors as anticancer agents and identify the novel cellular pathways under GSTO1 regulation in colorectal cancer.

PMID- 27703243 TI - Reverse-topology membrane scission by the ESCRT proteins. AB - The narrow membrane necks formed during viral, exosomal and intra-endosomal budding from membranes, as well as during cytokinesis and related processes, have interiors that are contiguous with the cytosol. Severing these necks involves action from the opposite face of the membrane as occurs during the well characterized formation of coated vesicles. This 'reverse' (or 'inverse') topology membrane scission is carried out by the endosomal sorting complex required for transport (ESCRT) proteins, which form filaments, flat spirals, tubes and conical funnels that are thought to direct membrane remodelling and scission. Their assembly, and their disassembly by the ATPase vacuolar protein sorting-associated 4 (VPS4) have been intensively studied, but the mechanism of scission has been elusive. New insights from cryo-electron microscopy and various types of spectroscopy may finally be close to rectifying this situation. PMID- 27703250 TI - A novel three-axis cylindrical hohlraum designed for inertial confinement fusion ignition. AB - A novel ignition hohlraum for indirect-drive inertial confinement fusion is proposed, which is named three-axis cylindrical hohlraum (TACH). TACH is a kind of 6 laser entrance holes (LEHs) hohlraum, which is orthogonally jointed of three cylindrical hohlraums. Laser beams are injected through every entrance hole with the same incident angle of 55 degrees . A view-factor simulation result shows that the time-varying drive asymmetry of TACH is less than 1.0% in the whole drive pulse period without any supplementary technology. Coupling efficiency of TACH is close to that of 6 LEHs spherical hohlraum with corresponding size. Its plasma-filling time is close to that of typical cylindrical ignition hohlraum. Its laser plasma interaction has as low backscattering as the outer cone of the cylindrical ignition hohlraum. Therefore, TACH combines most advantages of various hohlraums and has little predictable risk, providing an important competitive candidate for ignition hohlraum. PMID- 27703251 TI - Towards Dynamic Contrast Specific Ultrasound Tomography. AB - We report on the first study demonstrating the ability of a recently-developed, contrast-enhanced, ultrasound imaging method, referred to as cumulative phase delay imaging (CPDI), to image and quantify ultrasound contrast agent (UCA) kinetics. Unlike standard ultrasound tomography, which exploits changes in speed of sound and attenuation, CPDI is based on a marker specific to UCAs, thus enabling dynamic contrast-specific ultrasound tomography (DCS-UST). For breast imaging, DCS-UST will lead to a more practical, faster, and less operator dependent imaging procedure compared to standard echo-contrast, while preserving accurate imaging of contrast kinetics. Moreover, a linear relation between CPD values and ultrasound second-harmonic intensity was measured (coefficient of determination = 0.87). DCS-UST can find clinical applications as a diagnostic method for breast cancer localization, adding important features to multi parametric ultrasound tomography of the breast. PMID- 27703252 TI - The functional activity and effective connectivity of pulvinar are modulated by individual differences in threat-related attentional bias. AB - The pulvinar is important in selective attention, particularly to visual stimuli under the focus of attention. However, the pulvinar is assumed to process emotional stimuli even outside the focus of attention, because of its tight connection with the amygdala. We therefore investigated how unattended emotional stimuli affect the pulvinar and its effective connectivity (EC) while considering individual differences in selective attention. fMRI in 41 healthy human subjects revealed that the amygdala, but not the pulvinar, more strongly responded to unattended fearful faces than to unattended neutral faces (UF > UN), although we observed greater EC from the pulvinar to the amygdala. Interestingly, individuals with biased attention toward threat (i.e., attentional bias) showed significantly increased activity (UF > UN) and reduced grey matter volume in the pulvinar. These individuals also exhibited stronger EC from the pulvinar to the attention related frontoparietal network (FPN), whereas individuals with greater attentional control showed more enhanced EC from the pulvinar to the amygdala, but not the FPN (UF > UN). The pulvinar may filter unattended emotional stimuli whose sensitivity depends on individual threat-related attentional bias. The connectivity patterns of the pulvinar may thus be determined based on individual differences in threat-related attentional bias and attentional control. PMID- 27703253 TI - Surface step terrace tuned microstructures and dielectric properties of highly epitaxial CaCu3Ti4O12 thin films on vicinal LaAlO3 substrates. AB - Controllable interfacial strain can manipulate the physical properties of epitaxial films and help understand the physical nature of the correlation between the properties and the atomic microstructures. By using a proper design of vicinal single-crystal substrate, the interface strain in epitaxial thin films can be well controlled by adjusting the miscut angle via a surface-step-terrace matching growth mode. Here, we demonstrate that LaAlO3 (LAO) substrates with various miscut angles of 1.0 degrees , 2.75 degrees , and 5.0 degrees were used to tune the dielectric properties of epitaxial CaCu3Ti4O12 (CCTO) thin films. A model of coexistent compressive and tensile strained domains is proposed to understand the epitaxial nature. Our findings on the self-tuning of the compressive and tensile strained domain ratio along the interface depending on the miscut angle and the stress relaxation mechanism under this growth mode will open a new avenue to achieve CCTO films with high dielectric constant and low dielectric loss, which is critical for the design and integration of advanced heterostructures for high performance capacitance device applications. PMID- 27703254 TI - Fully Controllable Pancharatnam-Berry Metasurface Array with High Conversion Efficiency and Broad Bandwidth. AB - Metasurfaces have powerful abilities to manipulate the properties of electromagnetic waves flexibly, especially the modulation of polarization state for both linearly polarized (LP) and circularly polarized (CP) waves. However, the transmission efficiency of cross-polarization conversion by a single-layer metasurface has a low theoretical upper limit of 25% and the bandwidth is usually narrow, which cannot be resolved by their simple additions. Here, we efficiently manipulate polarization coupling in multilayer metasurface to promote the transmission of cross-polarization by Fabry-Perot resonance, so that a high conversion coefficient of 80-90% of CP wave is achieved within a broad bandwidth in the metasurface with C-shaped scatters by theoretical calculation, numerical simulation and experiments. Further, fully controlling Pancharatnam-Berry phase enables to realize polarized beam splitter, which is demonstrated to produce abnormal transmission with high conversion efficiency and broad bandwidth. PMID- 27703255 TI - Effects of histone acetylation on superoxide dismutase 1 gene expression in the pathogenesis of senile cataract. AB - Histone acetylation plays key roles in gene expression, but its effects on superoxide dismutase 1 (SOD1) expression in senile cataract remains unknown. To address this problem, the study was to investigate the influence of histone acetylation on SOD1 expression and its effects in the pathogenesis of senile cataract. Senile cataract was classified into three types-nuclear cataract (NC), cortical cataract (CC), and posterior subcapsular cataract (SC)-using the Lens Opacities Classification System III. In senile cataracts, SOD1 expression decreased significantly. Both H3 and H4 were deacetylated at -600 bp of the SOD1 promoter of cataract lenses, and hypoacetylated at -1500, -1200, and -900 bp. In hypoacetylated histones, the hypoacetylation pattern differed among the cataracts. In vitro, anacardic acid (AA) significantly reduced H3 and H4 acetylation at the SOD1 promoter, decreased protein expression, and induced cataract formation in rabbits. AA also inhibited HLEC viability and increased cell apoptosis. In contrast, trichostatin A (TSA) was able to efficaciously stop AA's effects on both rabbit lenses and HLECs. Decreased histone acetylation at the SOD1 promoter is associated with declined SOD1 expression in senile cataracts. Histone acetylation plays an essential role in the regulation of SOD1 expression and in the pathogenesis of senile cataracts. PMID- 27703256 TI - Feature Subset Selection for Cancer Classification Using Weight Local Modularity. AB - Microarray is recently becoming an important tool for profiling the global gene expression patterns of tissues. Gene selection is a popular technology for cancer classification that aims to identify a small number of informative genes from thousands of genes that may contribute to the occurrence of cancers to obtain a high predictive accuracy. This technique has been extensively studied in recent years. This study develops a novel feature selection (FS) method for gene subset selection by utilizing the Weight Local Modularity (WLM) in a complex network, called the WLMGS. In the proposed method, the discriminative power of gene subset is evaluated by using the weight local modularity of a weighted sample graph in the gene subset where the intra-class distance is small and the inter-class distance is large. A higher local modularity of the gene subset corresponds to a greater discriminative of the gene subset. With the use of forward search strategy, a more informative gene subset as a group can be selected for the classification process. Computational experiments show that the proposed algorithm can select a small subset of the predictive gene as a group while preserving classification accuracy. PMID- 27703257 TI - Computer keyboard interaction as an indicator of early Parkinson's disease. AB - Parkinson's disease (PD) is a slowly progressing neurodegenerative disease with early manifestation of motor signs. Objective measurements of motor signs are of vital importance for diagnosing, monitoring and developing disease modifying therapies, particularly for the early stages of the disease when putative neuroprotective treatments could stop neurodegeneration. Current medical practice has limited tools to routinely monitor PD motor signs with enough frequency and without undue burden for patients and the healthcare system. In this paper, we present data indicating that the routine interaction with computer keyboards can be used to detect motor signs in the early stages of PD. We explore a solution that measures the key hold times (the time required to press and release a key) during the normal use of a computer without any change in hardware and converts it to a PD motor index. This is achieved by the automatic discovery of patterns in the time series of key hold times using an ensemble regression algorithm. This new approach discriminated early PD groups from controls with an AUC = 0.81 (n = 42/43; mean age = 59.0/60.1; women = 43%/60%;PD/controls). The performance was comparable or better than two other quantitative motor performance tests used clinically: alternating finger tapping (AUC = 0.75) and single key tapping (AUC = 0.61). PMID- 27703258 TI - New low-flux mixed matrix membranes that offer superior removal of protein-bound toxins from human plasma. AB - Hemodialysis is a widely available and well-established treatment for patients with End Stage Renal Disease (ESRD). However, although life-sustaining, patient mortality rates are very high. Several recent studies corroborated the link between dialysis patients' outcomes and elevated levels of protein-bound uremic toxins (PBUT) that are poorly removed by conventional hemodialysis. Therefore, new treatments are needed to improve their removal. Recently, our group showed that the combination of dialysis and adsorption on one membrane, the mixed matrix membrane (MMM), can effectively remove those toxins from human plasma. However, these first MMMs were rather large in diameter and their mass transport characteristics needed improvement before application in the clinical setting. Therefore, in this study we developed a new generation of MMMs that have a smaller diameter and optimized characteristics offering superior ability in removing the PBUT indoxyl sulfate (IS) and p-cresyl sulfate (pCS) in comparison to first generation MMMs (30 and 125% respectively), as well as, a commercial dialysis membrane (more than 100% better removal). PMID- 27703259 TI - Deficiency in Toll-interacting protein (Tollip) skews inflamed yet incompetent innate leukocytes in vivo during DSS-induced septic colitis. AB - Functionally compromised neutrophils contribute to adverse clinical outcomes in patients with severe inflammation and injury such as colitis and sepsis. However, the ontogeny of dysfunctional neutrophil during septic colitis remain poorly understood. We report that the dysfunctional neutrophil may be derived by the suppression of Toll-interacting-protein (Tollip). We observed that Tollip deficient neutrophils had compromised migratory capacity toward bacterial product fMLF due to reduced activity of AKT and reduction of FPR2, reduced potential to generate bacterial-killing neutrophil extra-cellular trap (NET), and compromised bacterial killing activity. On the other hand, Tollip deficient neutrophils had elevated levels of CCR5, responsible for their homing to sterile inflamed tissues. The inflamed and incompetent neutrophil phenotype was also observed in vivo in Tollip deficient mice subjected to DSS-induced colitis. We observed that TUDCA, a compound capable of restoring Tollip cellular function, can potently alleviate the severity of DSS-induced colitis. In humans, we observed significantly reduced Tollip levels in peripheral blood collected from human colitis patients as compared to blood samples from healthy donors. Collectively, our data reveal a novel mechanism in Tollip alteration that underlies the inflamed and incompetent polarization of neutrophils leading to severe outcomes of colitis. PMID- 27703262 TI - 4-Aminopyridine sequesters intracellular Ca2+ which triggers exocytosis in excitable and non-excitable cells. AB - 4-aminopyridine is commonly used to stimulate neurotransmitter release resulting from sustained plasma membrane depolarization and Ca2+-influx from the extracellular space. This paper elucidated unconventional mechanism of 4 aminopyridine-stimulated glutamate release from neurons and non-neuronal cells which proceeds in the absence of external Ca2+. In brain nerve terminals, primary neurons and platelets 4-aminopyridine induced the exocytotic release of glutamate that was independent of external Ca2+ and was triggered by the sequestration of Ca2+ from intracellular stores. The initial level of 4-aminopyridine-stimulated glutamate release from neurons in the absence or presence of external Ca2+ was subequal and the difference was predominantly associated with subsequent tonic release of glutamate in Ca2+-supplemented medium. The increase in [Ca2+]i and the secretion of glutamate stimulated by 4-aminopyridine in Ca2+-free conditions have resulted from Ca2+ efflux from endoplasmic reticulum and were abolished by intracellular free Ca2+ chelator BAPTA. This suggests that Ca2+ sequestration plays a profound role in the 4-aminopyridine-mediated stimulation of excitable and non-excitable cells. 4-Aminopyridine combines the properties of depolarizing agent with the ability to sequester intracellular Ca2+. The study unmasks additional mechanism of action of 4-aminopyridine, an active substance of drugs for treatment of multiple sclerosis and conditions related to reduced Ca2+ efflux from intracellular stores. PMID- 27703260 TI - Dual targeting of ANGPT1 and TGFBR2 genes by miR-204 controls angiogenesis in breast cancer. AB - Deregulated expression of microRNAs has been associated with angiogenesis. Studying the miRNome of locally advanced breast tumors we unsuspectedly found a dramatically repression of miR-204, a small non-coding RNA with no previous involvement in tumor angiogenesis. Downregulation of miR-204 was confirmed in an independent cohort of patients and breast cancer cell lines. Gain-of-function analysis indicates that ectopic expression of miR-204 impairs cell proliferation, anchorage-independent growth, migration, invasion, and the formation of 3D capillary networks in vitro. Likewise, in vivo vascularization and angiogenesis were suppressed by miR-204 in a nu/nu mice model. Genome-wide profiling of MDA-MB 231 cells expressing miR-204 revealed changes in the expression of hundred cancer related genes. Of these, we focused on the study of pro-angiogenic ANGPT1 and TGFbetaR2. Functional analysis using luciferase reporter and rescue assays confirmed that ANGPT1 and TGFbetaR2 are novel effectors downstream of miR-204. Accordingly, an inverse correlation between miR-204 and ANGPT1/TGFbetaR2 expression was found in breast tumors. Knockdown of TGFbetaR2, but not ANGPT1, impairs cell proliferation and migration whereas inhibition of both genes inhibits angiogenesis. Taken altogether, our findings reveal a novel role for miR 204/ANGPT1/TGFbetaR2 axis in tumor angiogenesis. We propose that therapeutic manipulation of miR-204 levels may represent a promising approach in breast cancer. PMID- 27703261 TI - Transcriptome and Metabolite analysis reveal candidate genes of the cardiac glycoside biosynthetic pathway from Calotropis procera. AB - Calotropis procera is a medicinal plant of immense importance due to its pharmaceutical active components, especially cardiac glycosides (CG). As genomic resources for this plant are limited, the genes involved in CG biosynthetic pathway remain largely unknown till date. Our study on stage and tissue specific metabolite accumulation showed that CG's were maximally accumulated in stems of 3 month old seedlings. De novo transcriptome sequencing of same was done using high throughput Illumina HiSeq platform generating 44074 unigenes with average mean length of 1785 base pair. Around 66.6% of unigenes were annotated by using various public databases and 5324 unigenes showed significant match in the KEGG database involved in 133 different pathways of plant metabolism. Further KEGG analysis resulted in identification of 336 unigenes involved in cardenolide biosynthesis. Tissue specific expression analysis of 30 putative transcripts involved in terpenoid, steroid and cardenolide pathways showed a positive correlation between metabolite and transcript accumulation. Wound stress elevated CG levels as well the levels of the putative transcripts involved in its biosynthetic pathways. This result further validated the involvement of identified transcripts in CGs biosynthesis. The identified transcripts will lay a substantial foundation for further research on metabolic engineering and regulation of cardiac glycosides biosynthesis pathway genes.

AB - The flow of ions through membrane channels is precisely regulated by gates. The architecture and function of these elements have been studied extensively, shedding light on the mechanisms underlying gating. Recent investigations have focused on ion occupancy of the channel's selectivity filter and its ability to alter gating, with most studies involving prokaryotic K+ channels. Some studies used large quaternary ammonium blocker molecules to examine the effects of altered ionic flux on gating. However, the absence of blocking events that are visibly distinct from closing events in K+ channels makes unambiguous interpretation of data from single channel recordings difficult. In this study, the large K+ conductance of the RyR2 channel permits direct observation of blocking events as distinct subconductance states and for the first time demonstrates the differential effects of blocker molecules on channel gating. This experimental platform provides valuable insights into mechanisms of blocker induced modulation of ion channel gating.

AB - Males of all species of the parasitic wasp genus Nasonia use (4R,5S)-5-hydroxy-4 decanolide (RS) as component of their sex pheromone while only N. vitripennis (Nv), employs additionally (4R,5R)-5-hydroxy-4-decanolide (RR). Three genes coding for the NAD+-dependent short-chain dehydrogenases/reductases (SDRs) NV10127, NV10128, and NV10129 are linked to the ability of Nv to produce RR. Here we show by assaying recombinant enzymes that SDRs from both Nv and N. giraulti (Ng), the latter a species with only RS in the pheromone, epimerise RS into RR and vice versa with (4R)-5-oxo-4-decanolide as an intermediate. Nv-derived SDR orthologues generally had higher epimerisation rates, which were also influenced by NAD+ availability. Semiquantitative protein analyses of the pheromone glands by tandem mass spectrometry revealed that NV10127 as well as NV10128 and/or NV10129 were more abundant in Nv compared to Ng. We conclude that the interplay of differential expression patterns and SDR epimerisation rates on the ancestral pheromone component RS accounts for the evolution of a novel pheromone phenotype in Nv.

AB - Drug resistance elicited by cancer cells continue to cause huge problems world wide, for example, tens of thousands of patients are suffering from taxol resistant human ovarian cancer. However, its biochemical mechanisms remain unclear. Sphingolipid metabolic dysregulation has been increasingly regarded as one of the drug-resistant mechanisms for various cancers, which in turn provides potential targets for overcoming the resistance. In the current study, a well established LC-MS based sphingolipidomic approach was applied to investigate the sphingolipid metabolism of A2780 and taxol-resistant A2780 (A2780T) human ovarian cancer cell lines. 102 sphingolipids (SPLs) were identified based on accurate mass and characteristic fragment ions, among which 12 species have not been reported previously. 89 were further quantitatively analyzed by using multiple reaction monitoring technique. Multivariate analysis revealed that the levels of 52 sphingolipids significantly altered in A2780T cells comparing to those of A2780 cells. These alterations revealed an overall increase of sphingomyelin levels and significant decrease of ceramides, hexosylceramides and lactosylceramides, which concomitantly indicated a deviated SPL metabolism in A2780T. This is the most comprehensive sphingolipidomic analysis of A2780 and A2780T, which investigated significantly changed sphingolipid profile in taxol resistant cancer cells. The aberrant sphingolipid metabolism in A2780T could be one of the mechanisms of taxol-resistance. PMID- 27703265 TI - The Prognostic Value of PLR in Lung Cancer, a Meta-analysis Based on Results from a Large Consecutive Cohort. AB - Recently, many studies have been conducted to explore prognostic value of platelet to lymphocyte ratio (PLR) for patients with lung cancer, while the results remain controversial. We collected pretreatment, clinicopathological and follow-up data of 1388 lung cancer patients receiving surgery between 2006 and 2011 in our hospital, and reviewed relevant articles from Embase, Pubmed, Web of science databases, then performed a meta-analysis to clarify the relationship between PLR and prognosis of lung cancer patients. Finally, 11 articles with our study were included, results indicated elevated PLR was negatively related to overall survival (HR = 1.33, 95% CI: 1.10-1.62), but not related to progress-free survival (HR = 1.21, 95% CI: 0.97-1.49). Subgroup analysis suggested high PLR was correlated with poor survival in non-small cell lung cancer (HR = 1.43, 95% CI: 1.14-1.78), but not in small cell lung cancer (HR = 1.10, 95% CI: 0.76-1.58). Besides, for patients treated by chemotherapy or radiotherapy (HR = 1.66, 95% CI: 1.15-2.38) and patients in late stage (HR = 1.41, 95% CI: 1.19-1.68), PLR had significantly prognostic value. Additionally, the result was significant for patients when cut-off value of PLR was between 150 and 200 (HR = 1.47, 95% CI: 1.18-1.82). In Conclusion, this meta-analysis revealed that elevated PLR was associated with poor prognosis in lung cancer. PMID- 27703267 TI - Dietary resources shape the adaptive changes of cyanide detoxification function in giant panda (Ailuropoda melanoleuca). AB - The functional adaptive changes in cyanide detoxification in giant panda appear to be response to dietary transition from typical carnivore to herbivorous bear. We tested the absorption of cyanide contained in bamboo/bamboo shoots with a feeding trial in 20 adult giant pandas. We determined total cyanide content in bamboo shoots and giant panda's feces, levels of urinary thiocyanate and tissue rhodanese activity using color reactions with a spectrophotometer. Rhodanese expression in liver and kidney at transcription and translation levels were measured using real-time RT-PCR and immunohistochemistry, respectively. We compared differences of rhodanese activity and gene expressions among giant panda, rabbit (herbivore) and cat (carnivore), and between newborn and adult giant pandas. Bamboo shoots contained 3.2 mg/kg of cyanide and giant pandas absorbed more than 65% of cyanide. However, approximately 80% of absorbed cyanide was metabolized to less toxic thiocyanate that was discharged in urine. Rhodanese expression and activity in liver and kidney of giant panda were significantly higher than in cat, but lower than in rabbit (all P < 0.05). Levels in adult pandas were higher than that in newborn cub. Phylogenetic analysis of both nucleotide and amino acid sequences of the rhodanese gene supported a closer relationship of giant panda with carnivores than with herbivores. PMID- 27703268 TI - Optogenetic activation of septal GABAergic afferents entrains neuronal firing in the medial habenula. AB - The medial habenula (MHb) plays an important role in nicotine-related behaviors such as nicotine aversion and withdrawal. The MHb receives GABAergic input from the medial septum/diagonal band of Broca (MS/DB), yet the synaptic mechanism that regulates MHb activity is unclear. GABA (gamma -aminobutyric acid) is a major inhibitory neurotransmitter activating both GABAA receptors and GABAB receptors. Depending on intracellular chloride concentration, however, GABAA receptors also function in an excitatory manner. In the absence of various synaptic inputs, we found that MHb neurons displayed spontaneous tonic firing at a rate of about ~4.4 Hz. Optogenetic stimulation of MS/DB inputs to the MHb evoked GABAA receptor mediated synaptic currents, which produced stimulus-locked neuronal firing. Subsequent delayed yet lasting activation of GABAB receptors attenuated the intrinsic tonic firing. Consequently, septal GABAergic input alone orchestrates both excitatory GABAA and inhibitory GABAB receptors, thereby entraining the firing of MHb neurons. PMID- 27703269 TI - Rapid detection of abrin in foods with an up-converting phosphor technology-based lateral flow assay. AB - Abrin is a natural plant toxin found in the seeds of Abrus precatorius. It may be used for food poisoning or bioterrorism, seriously endangering public health. In this study, a reliable method for the rapid detection of abrin in foods was developed, based on an up-converting phosphor technology-based lateral flow assay (abrin-UPT-LFA). Nine high-affinity monoclonal antibodies (mAbs) against abrin were prepared, and the optimum mAbs (mAb-6F4 and mAb-10E11) were selected for use in the assay in double-antibody-sandwich mode. The assay was confirmed to be specific for abrin, with a detection sensitivity of 0.1 ng mL-1 for standard abrin solutions. Good linearity was observed for abrin quantitation from 0.1 to 1000 ng mL-1 (r = 0.9983). During the analysis of various abrin-spiked food samples, the assay showed strong sample tolerance and a satisfactory limit of detection for abrin (0.5-10 ng g-1 for solid and powdered samples; 0.30-0.43 ng mL-1 for liquid samples). The analysis of suspected food samples, from sample treatment to result feed-back, could be completed by non-professionals within 20 min. Therefore, the abrin-UPT-LFA is a rapid, sensitive, and reliable method for the on-site detection of abrin in foods. PMID- 27703270 TI - Cold tolerance and silencing of three cold-tolerance genes of overwintering Chinese white pine larvae. AB - The values of physiological indices and the enzymes activities involved in the overwintering stage were studied in D. armandi larvae in each month from October 2014 to March 2015. The sorbitol, trehalose and glycerol values initially tended to increase as the ambient temperature decreased, before declining until the end of the winter. The activities of four enzymes (SOD, CAT, LDH and AchE) decreased, whereas POD, PK and MDH showed opposite trends in activity. Other enzyme activities (those of TPS, SDH and GLK) were low during the overwintering period and later increased and stabilized during spring. In this study, a polymerase chain reaction (PCR) genes of SDH, TPS and GLK was utilized to identify DarmSDH, DarmTPS and DarmGLK in D. armandi. They were found to be abundantly expressed during the overwintering stage by quantitative real-time PCR (qRT-PCR) analyses; by contrast, these three genes showed higher expression levels in December 2014 than in May 2015. The qRT-PCR results demonstrated that the reduction of mRNA expression levels was significant in DarmSDH-, DarmTPS- and DarmGLK-dsRNA-treated D. armandi compared with water-injected and non-injected controls. The mortality responses at low temperature were also increased in the dsRNA-treated D. armandi compared with the controls. PMID- 27703272 TI - Experimental characterization of Raman overlaps between mode-groups. AB - Mode-division multiplexing has the potential to further increase data transmission capacity through optical fibers. In addition, distributed Raman amplification is a promising candidate for multi-mode signal amplification due to its desirable noise properties and the possibility of mode-equalized gain. In this paper, we present an experimental characterization of the intermodal Raman intensity overlaps of a few-mode fiber using backward-pumped Raman amplification. By varying the input pump power and the degree of higher order mode-excitation for the pump and the signal in a 10 km long two-mode fiber, we are able to characterize all intermodal Raman intensity overlaps. Using these results, we perform a Raman amplification measurement and demonstrate a mode-differential gain of only 0.25 dB per 10 dB overall gain. This is, to the best of our knowledge, the lowest mode differential gain achieved for amplification of mode division multiplexed signals in a single fiber. PMID- 27703271 TI - Pioglitazone Ameliorates Smooth Muscle Cell Proliferation in Cuff-Induced Neointimal Formation by Both Adiponectin-Dependent and -Independent Pathways. AB - The aim of this study is to elucidate to what degree adiponectin is involved in TZD-mediated amelioration of neointimal formation. We investigated the effect of 3- or 8-weeks' pioglitazone on cuff-induced neointimal formation in adiponectin deficient (APN-KO) and wild-type (WT) mice. Pioglitazone for 3 weeks reduced neointimal formation in the WT mice with upregulation of the plasma adiponectin levels, but failed to reduce neointimal formation in the APN-KO mice, suggesting that pioglitazone suppressed neointimal formation by adiponectin-dependent mechanisms. Pioglitazone for 3 weeks suppressed vascular smooth muscle cell (VSMC) proliferation and increased AdipoR2 expression in the WT mice. In vitro, globular adiponectin activated AMPK through both AdipoR1 and AdipoR2, resulting in the inhibition of VSMC proliferation. Interestingly, 8-weeks' pioglitazone was reduced neointimal formation in APN-KO mice to degree similar to that seen in the WT mice, suggesting that pioglitazone can also suppress neointimal formation via a mechanism independent of adiponectin. Pioglitazone for 8 weeks completely abrogated the increased VSMC proliferation, along with a reduction of cyclin B1 and cyclin D1 expressions and cardiovascular risk profile in the APN-KO mice. In vitro, pioglitazone suppressed these expressions, leading to inhibition of VSMC proliferation. Pioglitazone suppresses neointimal formation via both adiponectin dependent and adiponectin-independent mechanisms. PMID- 27703273 TI - A Cretaceous origin for fire adaptations in the Cape flora. AB - Fire has had a profound effect on the evolution of worldwide biotas. The Cape Floristic Region is one of the world's most species-rich regions, yet it is highly prone to recurrent fires and fire-adapted species contribute strongly to the overall flora. It is hypothesized that the current fire regimes in the Cape could be as old as 6-8 million years (My), while indirect evidence indicates that the onset of fire could have reached 18 million years ago (Ma). Here, we trace the origin of fire-dependent traits in two monocot families that are significant elements in the fire-prone Cape flora. Our analysis shows that fire-stimulated flowering originated in the Cape Haemodoraceae 81 Ma, while fire-stimulated germination arose in the African Restionaceae at least 70 Ma, implying that wildfires have been a significant force in the evolution of the Cape flora at least 60 My earlier than previous estimates. Our results provide strong evidence for the presence of fire adaptations in the Cape from the Cretaceous, leading to the extraordinary persistence of a fire-adapted flora in this biodiversity hotspot, and giving support to the hypothesis that Cretaceous fire was a global phenomenon that shaped the evolution of terrestrial floras. PMID- 27703275 TI - Seven 365-Million-Year-Old Trilobites Moulting within a Nautiloid Conch. AB - A nautiloid conch containing many disarticulated exoskeletons of Omegops cornelius (Phacopidae, Trilobita) was found in the Upper Devonian Hongguleleng Formation of the northwestern margin of the Junggar Basin, NW China. The similar number of cephala, thoraces and pygidia, unbroken thoraces, explicit exuviae, and lack of other macrofossils in the conch, indicate that at least seven individual trilobites had moulted within the nautiloid living chamber, using the vacant chamber of a dead nautiloid as a communal place for ecdysis. This exuvial strategy manifests cryptic behaviour of trilobites, which may have resulted from the adaptive evolution induced by powerful predation pressure, unstable marine environments, and competition pressure of organisms occupying the same ecological niche in the Devonian period. The unusual presence of several trilobites moulting within a nautiloid conch is possibly associated with social behaviours in face of a serious crisis. New materials in this study open a window for understanding the survival strategy of marine benthic organisms, especially predator-prey interactions and the behavioural ecology of trilobites in the middle Palaeozoic. PMID- 27703276 TI - BDNF Val66Met Polymorphism Influences Visuomotor Associative Learning and the Sensitivity to Action Observation. AB - Motor representations in the human mirror neuron system are tuned to respond to specific observed actions. This ability is widely believed to be influenced by genetic factors, but no study has reported a genetic variant affecting this system so far. One possibility is that genetic variants might interact with visuomotor associative learning to configure the system to respond to novel observed actions. In this perspective, we conducted a candidate gene study on the Brain-derived neurotrophic factor (BDNF) Val66Met polymorphism, a genetic variant linked to motor learning in regions of the mirror neuron system, and tested the effect of this polymorphism on motor facilitation and visuomotor associative learning. In a single-pulse TMS study carried on 16 Met (Val/Met and Met/Met) and 16 Val/Val participants selected from a large pool of healthy volunteers, Met participants showed significantly less muscle-specific corticospinal sensitivity during action observation, as well as reduced visuomotor associative learning, compared to Val homozygotes. These results are the first evidence of a genetic variant tuning sensitivity to action observation and bring to light the importance of considering the intricate relation between genetics and associative learning in order to further understand the origin and function of the human mirror neuron system. PMID- 27703274 TI - Cross-inhibition of pathogenic agents and the host proteins they exploit. AB - The major limitations of pathogen-directed therapies are the emergence of drug resistance and their narrow spectrum of coverage. A recently applied approach directs therapies against host proteins exploited by pathogens in order to circumvent these limitations. However, host-oriented drugs leave the pathogens unaffected and may result in continued pathogen dissemination. In this study we aimed to discover drugs that could simultaneously cross-inhibit pathogenic agents, as well as the host proteins that mediate their lethality. We observed that many pathogenic and host-assisting proteins belong to the same functional class. In doing so we targeted a protease component of anthrax toxin as well as host proteases exploited by this toxin. We identified two approved drugs, ascorbic acid 6-palmitate and salmon sperm protamine, that effectively inhibited anthrax cytotoxic protease and demonstrated that they also block proteolytic activities of host furin, cathepsin B, and caspases that mediate toxin's lethality in cells. We demonstrated that these drugs are broad-spectrum and reduce cellular sensitivity to other bacterial toxins that require the same host proteases. This approach should be generally applicable to the discovery of simultaneous pathogen and host-targeting inhibitors of many additional pathogenic agents. PMID- 27703277 TI - Repeatability of cortisol stress response in the European sea bass (Dicentrarchus labrax) and transcription differences between individuals with divergent responses. AB - Understanding the stress responses of organisms is of importance in the performance and welfare of farmed animals, including fish. Especially fish in aquaculture commonly face stressors, and better knowledge of their responses may assist in proper husbandry and selection of breeding stocks. European sea bass (Dicentrarchus labrax), a species with high cortisol concentrations, is of major importance in this respect. The main objectives of the present study were to assess the repeatability and consistency of cortisol stress response and to identify differences in liver transcription profiles of European sea bass individuals, showing a consistent low (LR) or high (HR) cortisol response. The progeny of six full sib families was used, and sampled for plasma cortisol after an acute stress challenge once per month, for four consecutive months. Results suggest that cortisol responsiveness was a repeatable trait with LR and HR fish showing low or high resting, free and post-stress cortisol concentrations respectively. Finally, the liver transcription profiles of LR and HR fish showed some important differences, indicating differential hepatic regulation between these divergent phenotypes. These transcription differences were related to various metabolic and immunological processes, with 169 transcripts being transcribed exclusively in LR fish and 161 exclusively in HR fish. PMID- 27703278 TI - Ghrelin Exerts Analgesic Effects through Modulation of IL-10 and TGF-beta Levels in a Rat Model of Inflammatory Pain. AB - BACKGROUND: Ghrelin is a peptide with attenuating effect on inflammatory pain. Both anti- and pro-inflammatory mediators have a role in the nociception and development of pain and hyperalgesia. IL-10 and TGF-beta are anti-inflammatory cytokines and inhibit the expression of pro-inflammatory cytokines related to peripheral and central inflammatory pain. In this study, the effects of i.p. injection of ghrelin on the early and the late phases of pain, as well as serum levels of IL-10 and TGF-beta, as anti-inflammatory cytokines, were investigated in formalin-induced pain in male rats. METHODS: Adult male Wistar rats (n=48) were randomly divided into six groups: control, formalin+saline, ghrelin (40, 80, and 160 MUg/kg), and morphine. Ghrelin was administered i.p. 30 min before inducing pain by formalin. Pain induced by intraplantar (i.pl.) injection of 50 ul formalin 5%, and pain behavior was studied for 60 min. Serum IL-10 and TGF beta levels were assessed by ELISA method. RESULTS: The findings of the present study showed that ghrelin with high doses (80 and 160 MUg/kg) significantly reduced pain intensity in both the early and the late phases of pain. The serum levels of cytokines, IL-10, and TGF-beta1 showed a significant elevation with ghrelin at the dose of 160 MUg/kg. CONCLUSION: Ghrelin is effective in reducing the intensity of both the early and the late phases of inflammatory pain. It seems that ghrelin exerts its analgesic effects in part by increasing the serum levels of anti-inflammatory cytokines. PMID- 27703279 TI - An electrically resistive sheet of glial cells for amplifying signals of neuronal extracellular recordings. AB - Electrical signals of neuronal cells can be recorded non-invasively and with a high degree of temporal resolution using multielectrode arrays (MEAs). However, signals that are recorded with these devices are small, usually 0.01%-0.1% of intracellular recordings. Here, we show that the amplitude of neuronal signals recorded with MEA devices can be amplified by covering neuronal networks with an electrically resistive sheet. The resistive sheet used in this study is a monolayer of glial cells, supportive cells in the brain. The glial cells were grown on a collagen-gel film that is permeable to oxygen and other nutrients. The impedance of the glial sheet was measured by electrochemical impedance spectroscopy, and equivalent circuit simulations were performed to theoretically investigate the effect of covering the neurons with such a resistive sheet. Finally, the effect of the resistive glial sheet was confirmed experimentally, showing a 6-fold increase in neuronal signals. This technique feasibly amplifies signals of MEA recordings. PMID- 27703280 TI - In-situ guidance of individual neuronal processes by wet femtosecond-laser processing of self-assembled monolayers. AB - In-situ guidance of neuronal processes (neurites) is demonstrated by applying wet femtosecond-laser processing to an organosilane self-assembled monolayer (SAM) template. By scanning focused laser beam between cell adhesion sites, on which primary neurons adhered and extended their neurites, we succeeded in guiding the neurites along the laser-scanning line. This guidance was accomplished by multiphoton laser ablation of cytophobic SAM layer and subsequent adsorption of cell adhesion molecule, laminin, onto the ablated region. This technique allows us to arbitrarily design neuronal networks in vitro. PMID- 27703281 TI - Identification of Differentially Expressed Kinase and Screening Potential Anticancer Drugs in Papillary Thyroid Carcinoma. AB - Aim. We aim to identify protein kinases involved in the pathophysiology of papillary thyroid carcinoma (PTC) in order to provide potential therapeutic targets for kinase inhibitors and unfold possible molecular mechanisms. Materials and Methods. The gene expression profile of GSE27155 was analyzed to identify differentially expressed genes and mapped onto human protein kinases database. Correlation of kinases with PTC was addressed by systematic literature search, GO and KEGG pathway analysis. Results. The functional enrichment analysis indicated that "mitogen-activated protein kinases pathway" expression was extremely enriched, followed by "neurotrophin signaling pathway," "focal adhesion," and "GnRH signaling pathway." MAPK, SRC, PDGFRa, ErbB, and EGFR were significantly regulated to correct these pathways. Kinases investigated by the literature on carcinoma were considered to be potential novel molecular therapeutic target in PTC and application of corresponding kinase inhibitors could be possible therapeutic tool. Conclusion. SRC, MAPK, and EGFR were the most important differentially expressed kinases in PTC. Combined inhibitors may have high efficacy in PTC treatment by targeting these kinases.

AB - INTRODUCTION: Transfusion is an activity that assures sufficient supply of blood and blood components to treat the sick and injured. In transfusion departments is necessary to timely provide adequate amounts of blood and blood products for various surgical procedures. MATERIAL AND METHODS: To determine the total amount of preoperative requirements (BT/AB and BT/AB/MT) for blood and blood products in surgical departments of General Hospital "Prim. Dr. Abdulah Nakas" in the period from June 1, 2014 - December 31, 2014 and analyze the requirements for blood in relation to surgical procedures, surgical discipline, period, age and gender of patients. To determine the maximum consumption levels surgeries. RESULTS: The total amount of preoperative requirements for blood and blood products in surgical departments amounted to 927. Almost the same number of requests with a slightly higher percentage was in December and October and the lowest in June. The average age of patients was 52.2+/-20.1 years with the youngest patient aged 9 and the oldest at the age of 97 years. Women were more prevalent with 686 or 74% of the time compared to men. The largest number of requests for surgery elective cesarean section 208 (22.5%) with delivery wards, then for surgery or hip replacement 98 (10.6%). Maximum consumption for surgical operations Hysterectomy totalis abdominals 15 doses of blood. CONCLUSION: The largest number of requests were for elective cesarean section 208 (22.5%) with delivery wards, then for surgery or hip replacement with 98 (10.6%). Maximum consumed doses had gynecology surgery at Hysterectomy totalis abdominals 15 doses of blood, then orthopedics surgery at Primary hip prosthesis 11 doses. PMID- 27703283 TI - Inflammatory Cytokines as Risk Factors for Mortality After Acute Cardiac Events. AB - INTRODUCTION: Inflammatory markers have been identified as potential indicators of future adverse outcome after acute cardiac events. AIM: This study aimed to analyze baseline inflammatory cytokines levels in patients with acute heart failure (AHF) and/or acute coronary syndrome (ACS) according to survival. The main objective was to identify risk factors for mortality after an episode of AHF and/or ACS. METHODS: In this prospective longitudinal study 75 patients with the diagnosis of AHF and/or ACS were enrolled. Baseline laboratory and clinical data were retrieved. Serum and urine interleukin-6 (IL-6) and interleukin-18 (IL-18) levels, plasma B-type natriuretic peptide (BNP) and serum cystatin C values were determined. The primary outcome was in-hospital mortality while secondary outcome was six-month mortality. RESULTS: Median serum and urine IL-6 levels, serum and urine IL-18 levels, as well as median concentrations of plasma BNP and serum cystatin C, were significantly increased in deceased in comparison to surviving AHF and/or ACS patients. Univariate Cox regression analysis identified serum IL 6, serum IL-18, urine IL-6, urine IL-18 as well as serum cystatin C and Acute Physiology and Chronic Health Evaluation (APACHE) II score as risk factors for mortality after an episode of AHF and/or ACS. Multivariate Cox regression analysis revealed that only serum IL-6 is the independent risk factor for mortality after acute cardiac events (HR 61.7, 95% CI 2.1-1851.0; p=0.018). CONCLUSION: Present study demonstrated the strong prognostic value of serum IL-6 in predicting mortality of patients with AHF and/or ACS. PMID- 27703285 TI - Studying the Relation of Postprandial Triglyceride with Coronary Artery Disease (CAD). AB - BACKGROUND: Coronary artery disease (CAD) is the most common cause of mortality worldwide and determination of contributing factors is essential. AIM: This study was conducted to study the relation of postprandial triglyceride as a risk of coronary artery disease in patients with proven CAD by angiography, referred to 502 Hospital of Army in 2015. MATERIAL AND METHODS: This observational study conducted as a case-control and contained 80 male participants referred to 502 Hospital of Army. Half of these participants had proven CAD by angiography test and the other ones were healthy as a control group. Fasting serum triglyceride was evaluated in all participants and postprandial TG was checked 4 hours after a standard meal. Obtained data were analyzed by SPSS ver. 13. RESULTS: The results indicated that fasting TG and postprandial TG level were significantly higher in CAD patients (P-value=0.001). It was also shown evaluation of postprandial TG is more sensitive test than fasting TG in case of CAD patients. CONCLUSION: Our obtained results shown, evaluation of high level of postprandial TG is more reliable than fasting TG for patients whom suffer from CAD. PMID- 27703284 TI - Pre-operative Neutrophils/Lymphocyte Ratio in Rectal Cancer Patients with Preoperative Chemoradiotherapy. AB - BACKGROUND: Several studies have reported that an elevation in neutrophils/lymphocyte ratio (NLR) is correlated with poor survival in patients with colorectal cancer, but in rectal cancer (RC), it has been reported only in a few studies. It is necessary to separate colon cancer and rectal cancer to clarify the prognostic significance of NLR, especially in patients who received chemoradiotherapy. METHODS: It is a comparative, observational retrospective study of a cohort of 175 patients. We grouped the patients into two based on their NLR (0-3 vs. > 3) to correlate with disease-specific survival (DSS) and pathologic complete response (pCR). RESULTS: The average NLR was 2.65 + 1.32 (range 0.58-6.89), and 144 (82.3%) patients had an NLR of 0-3. The median follow up was 33.53 months. There were no differences in pCR between the two groups. The 5-year DSS was 78.8%. NLR did not correlate with survival. Mesorectal quality, pT3-4 tumors, lymph node metastasis, lymphovascular invasion, perineural invasion, positive margins and recurrence were statistically significant predictors of increased mortality in univariate analysis. In multivariate analysis, only overall recurrence correlated with poor survival. The analysis of the association of NLR with outcomes with different cut points (2.0, 2.5, 4 and 5) did not show differences in DSS and pCR. CONCLUSION: In our cohort, the NLR did not serve as a prognostic marker in patients with locally advanced rectal cancer and who received chemoradiotherapy and did not correlate with pCR as well. PMID- 27703286 TI - A Comparison Between the Hemodynamic Effects of Cisatracurium and Atracurium in Patient with Low Function of Left Ventricle who are Candidate for Open Heart Surgery. AB - BACKGROUND: The need for muscle relaxants in general anesthesia in different surgeries including cardiac surgeries, and the type of relaxant to be used considering its different hemodynamic effects on patients with heart disease can be of considerable importance. In this study, the hemodynamic effects of two muscle relaxants, Cisatracurium and Atracurium in patients whit low function of left ventricle who are candidate for open heart surgery have been considered. METHOD: This study has been designed as a randomized prospective double-blind clinical trial. The target population included all adult patients with heart disease whose ejection fraction reported by echocardiography or cardiac catheterization was 35% or less before the surgery, and were candidate for open heart surgery in Shahid Rajaei Heart Center. Taking into account the inclusion and exclusion criteria, the patients were randomly placed in two groups of 30 people each. In the induction stage, all the patients received midazolam, etomidate, and one of the considered muscle relaxant, either 0.2 mg/kg of cisatracurium or 0.5mg/kg of Atracurium within one minute. In the maintenance stage of anesthesia, the patients were administered by infusion of midazolam, sufentanil and the same muscle relaxant used in the induction stage. The hemodynamic indexes were recorded and evaluated in different stages of anesthesia and surgery as well as prior to transfer to ICU. RESULTS: In regard with descriptive indexes (age and sex distributions, premedication with cardiac drugs, ejection fraction before surgery, basic disease) there was no statistically significant difference between the groups. CONCLUSIONS: The significant difference of hemodynamic indexes between the two groups of this study, and the need for hemodynamic stability in all stages of surgery for patients with low function of left ventricle who are candidate for open heart surgery, proves that administering Cisatracurium as the muscle relaxant is advantageous and better. PMID- 27703287 TI - A Comparison of Prognostic Value of the Levels of ProBNP and Troponin T in Patients with Acute Coronary Syndrome (ACS). AB - INTRODUCTION: The propeptide of brain natriuretic peptide (ProBNP) is used for the diagnosis of left ventricle dysfunction and heart failure. In patients with an Acute Coronary Syndrome (ACS) it can contribute to both short and long term prognosis of cardiovascular events that could be very important for management and therapy of these patients. AIM: The aim of this study was to evaluate the prognostic value of ProBNP for the clinical course after an acute coronary syndrome, compared with that of cardiac troponine T (cTnT) and the risk stratification of patients with acute coronary syndrome, both during hospitalization and six months later. METHODS: We studied 390 patients (256 men, 134 women, mean age 66.04+12.38) with an acute coronary syndrome who were hospitalized in the Coronary Unit of our cardiology clinic. We studied epidemiological and clinical data and biochemical markers were examined as prognostic factors for clinical course intrahospital and during six months follow up. RESULTS: In the majority of patients, a myocardial infarction without ST elevation was diagnosed (NSTEMI) (193 patients 49.49%) while 167 patients (42.82%) had a myocardial infarction with ST elevation (STEMI) and the remaining 30 patients (7.69%) had unstable angina. Patients had multiple risk factors for coronary heart disease. The levels of ProBNP were significantly elevated in patients with STEMI (p=0.003) and NSTEMI (p=0.002) who died or experienced an adverse event (angina, myocardial infarction, cardiogenic shock, congestive heart failure, arrhythmias) during hospitalization. After six months of follow-up, patients who had an adverse event had higher levels of ProBNP. There was no difference in troponine T levels in patients with STEMI and NSTEMI who had adverse events compared with the others, either during hospitalization or after six months. CONCLUSION: The level of ProBNP is an important predictor of cardiovascular events in patients with acute coronary syndrome. This study showed that it provides better predictive power than the troponine T. PMID- 27703288 TI - Blood Pressure Control in Hypertensive Patients, Cardiovascular Risk Profile and the Prevalence of Masked Uncontrolled Hypertension (MUCH). AB - INTRODUCTION: The term masked hypertension (MH) should be used for untreated individuals who have normal office blood pressure but elevated ambulatory blood pressure. For treated patients, this condition should be termed masked uncontrolled hypertension (MUCH). RESEARCH OBJECTIVES: Masked uncontrolled hypertension (MUCH) has gone unrecognized because few studies have used 24-h ABPM to determine the prevalence of suboptimal BP control in seemingly well-treated patients, and there are few such studies in large cohorts of treated patients attending usual clinical practice. This is important because masked hypertension is associated with a high risk of cardiovascular events. This study was conducted to obtain more information about the association between hypertension and other CV risk factors, about office and ambulatory blood pressure (BP) control as well as on cardiovascular (CV) risk profile in treated hypertensive patients, also to define the prevalence and characteristics of masked uncontrolled hypertension (MUCH) among treated hypertensive patients in routine clinical practice. PATIENTS AND METHODS: In this study 2514 male and female patients were included during a period of 5 years follow up. All patients have ambulatory blood pressure monitoring (ABPM) for at least 24h. We identified patients with treated and controlled BP according to current international guidelines (clinic BP, 140/90mmHg). Cardiovascular risk assessment was based on personal history, clinic BP values, as well as target organ damage evaluation. Masked uncontrolled hypertension (MUCH) was diagnosed in these patients if despite controlled clinic BP, the mean 24-h ABPM average remained elevated (24-h systolic BP >=130mmHg and/or 24-h diastolic BP >=80mmHg). RESULTS: Patients had a mean age of 60.2+10 years, and the majority of them (94.6%) were followed by specialist physicians. Average clinic BP was 150.4+16/89.9+12 mmHg. About 70% of patients displayed a very high-risk profile. Ambulatory blood pressure monitoring (ABPM) was performed in all recruited patients for at least 24h. Despite the combined medical treatment (78% of the patients), clinic control (<140/90 mmHg) was achieved in only 26.2% of patients, the corresponding control rate for ambulatory BP (<130/80 mmHg) being 32.7%. From 2514 patients with treated BP, we identified 803 with treated and controlled office BP control (<140/90 mmHg), of whom 258 patients (32.1%) had MUCH according to 24-h ABPM criteria (mean age 57.2 years, 54.7% men). The prevalence of MUCH was slightly higher in males, patients with borderline clinic and office BP (130-139/80-89 mmHg), and patients at high cardiovascular risk (smokers, diabetes, obesity). Masked uncontrolled hypertension (MUCH) was most often due to poor control of nocturnal BP, with the proportion of patients in whom MUCH was solely attributable to an elevated nocturnal BP almost double that solely attributable to daytime BP elevation (22.3 vs. 10.1%, P 0.001). CONCLUSION: The prevalence of masked suboptimal BP control in patients with treated and well-controlled clinic BP is high. The characteristics of patients with MUCH (male, longer duration of hypertension, obesity, smoking history, and diabetes) indicate that this is a higher-risk group with most to gain from improved BP. PMID- 27703289 TI - Comparison of Manual Refraction Versus Autorefraction in 60 Diabetic Retinopathy Patients. AB - AIM: The purpose of the study was to evaluate the comparison of manual refraction versus autorefraction in diabetic retinopathy patients. MATERIAL AND METHODS: The study was conducted at the Be'sat Army Hospital from 2013-2015. In the present study differences between two common refractometry methods (manual refractometry and Auto refractometry) in diagnosis and follow up of retinopathy in patients affected with diabetes is investigated. RESULTS: Our results showed that there is a significant difference in visual acuity score of patients between manual and auto refractometry. Despite this fact, spherical equivalent scores of two methods of refractometry did not show a significant statistical difference in the patients. CONCLUSION: Although use of manual refraction is comparable with autorefraction in evaluating spherical equivalent scores in diabetic patients affected with retinopathy, but in the case of visual acuity results from these two methods are not comparable. PMID- 27703290 TI - Short-term Outcomes of Induced Membrane Technique in Treatment of Long Bone Defects in Iran. AB - INTRODUCTION: Severe defects in long bones can be caused by several factors such as trauma that lead to open wound and secondary infections after surgery. Induced membrane technique is one of the therapeutic strategies that can be used for these patients. Due to importance of this method and lack of information about this technique in Iran. AIM: this study was performed to investigate technical strengths and weakness of induced membrane technique. MATERIAL AND METHODS: This case series study conducted on 21 patients with bone defects in the femur and tibia and metatarsal bones referred to orthopedic clinic of Rasoul Akram Hospital, Tehran, Iran, for induced membrane surgery in 2012-2015. Demographic and clinical data were obtained using history, clinical examinations and observations for each patient. Union achievement was the main outcome of this study, which was confirmed by radiographic findings and physical examination. Obtained data was analyzed by SPSS ver. 16. RESULTS: All patients were male except one and their mean age was 30.52 years old. Bone defects were in tibia, femur and metatarsus in 9, 9 and 3 patients, respectively. Three patients received soft tissue reconstruction with flap before induced membrane surgery. Age, defects size, cigarette addiction and drug use and delay to start the treatment had no significant effect on union status. In total, 90% of patients had successful surgery. CONCLUSION: using induced membrane technique in patients with defects in their long bone such as tibia, femur and metatarsus would lead to high success for reconstruction. PMID- 27703291 TI - Actual Contribution of Free to Total PSA Ratio in Prostate Diseases Differentiation. AB - OBJECTIVES: To determine significance and sensitivity of the Free to Total prostate specific antigen (PSA) ratio (%fPSA) in diagnosis of prostate cancer and to correlate its sensitivity and specificity with diagnosis. METHODS: Research included 220 patients, who had indication for biopsy (Clinic for Urology, University Clinical Center Sarajevo). RESULTS: Average age of patients was 64.6 +/- 8.1 years. Kruskal Wallis test indicates that there is a significant difference in age in relation to the diagnosis (KW chi2=12.508; p=0.006). The correlation between the %fPSA level and diagnosis is positive and statistically significant (r=0.211; p=0.002) in the sense that cancer patients have the lowest %fPSA. Analysis of the sensitivity at 95% specificity of %fPSA compared to particular diagnosis shows the highest sensitivity for prostate cancer - 20.61% (8.35-31.02) with statistically significant AUC p<0.05. Analysis of %fPSA test in detecting prostate cancer, at cut-off values <= 0.16, shows a sensitivity of 72.3% and specificity of 50.4 (at cut-off values <0.07, sensitivity is 8.4%, and specificity is 97.8%). CONCLUSION: PSA is organ specific but not cancer specific marker, whose total value, as well as the %fPSA serve as a basis, with a digitorectal exam, in the detection of prostate cancer. By increasing the cut-off values sensitivity of %fPSA increases and specificity decreases. %fPSA has a relative importance in the detection of prostate cancer, and should not be used as a guideline, without prior clinical examination.

AB - INTRODUCTION: Genovarum is a common orthopedic problem. Its optimal prompt treatment is an issue of importance. AIM: This study was conducted to determine the radiographic changes in patella bone before and after open wedge high tibial osteotomy. MATERIAL AND METHODS: In this quasi-experimental study, 43 patients were enrolled and underwent open wedge high tibial osteotomy and the radiographic and CT-scan indices including Q-Angle, Congruence Angle, Insall-Salvati index, and TTTG were measured and compared before and after surgery. RESULTS: The result revealed that all indices including Q-Angle, Congruence Angle, Insull-Salvati index, and TTTG were not significantly differed across the study (P > 0.05). There was no difference between DLFA values before and after the operation (P> 0.05), while MPTA values were significantly different before and after operation (p <0.001). CONCLUSIONS: Totally it may be concluded that imaging indices are not differed after open wedge high tibial osteotomy and monitoring for them is not necessary and they would have no prognostic role. PMID- 27703293 TI - Diagnostic Approach to Patients with Atypical Squamous Cells of Undetermined Significance Cytologic Findings on Cervix. AB - BACKGROUND: Atypical squamous cells of undetermined significance (ASCUS) is a term that refers to inflammatory, reactive and reparative processes which are atypical and of higher level and insufficient to be classified as cervical intraepithelial lesions (CIN). AIMS: Examine of frequency of HPV infection in ASCUS lesions and regression, stagnation and progression during six-month period. SUBJECTS AND METHODS: Prospective study was conducted over a period of 3 years. In private gynecological ambulance "Dr Mahira Jahic". Analysis of PAP smears and HPV typization have been done in 50 patients and PAP test has been repeated after six months. X2 test was used for statistical analysis. RESULTS: Analysis of 1784 PAP smears showed normal results in 86,6% (N-1530), and abnormal in 13% (N-254). ASCUS in 7,4% (N-133) and ASC-H in 0,5% (N-9), LSIL in 4,4% (N-80), HSIL in 1,3% (N-24), CIN II in 1,2% (N-20), CIN III in 0,2% (N-4). Progression occurred in 18% (9), persistence in 74% (37) and regression in 8%. Patients with ASC-H lesion 0,5% (N-9), PH results showed 22% (N-2) Carcinoma in situ, 33% (N-3) CIN II, 22% (N-2) CIN I and 22% (N-2) chronic cervicitis. Patients with CIN I in 88% (N-7) were positive on HPV of high risk. Patients with persistent ASCUS result were positive in 51% (N-19). The number of CIN I lesions found in women with ASCUS is bigger and statistically significant (p<0,05) in relation to number of CIN I findings found in regular examinations. CONCLUSION: Monitoring women with ASCUS lesion, especially HPV positive to high risk group is the best way of selection of women who should be treated and monitored in order to prevent cervical cancer. PMID- 27703294 TI - Treatment of Hypertension with Combination of Lisinopril/Hydrochlorothiazide. AB - INTRODUCTION: Paper is written on the basis of data collected in collaboration with family doctors in several cities in Bosnia and Herzegovina. MATERIAL AND METHODS: In this retrospective, randomized study was carried out processing of data collected by special design questionnaire from the field through studies and analyzes carried out in 5 health care institutions in the territory of Bosnia and Herzegovina. The study included 270 patients who underwent three consecutive medical examinations. RESULTS: Total reduction in blood pressure in average was 32.8 mmHg for systolic and 17.1 mmHg for diastolic, which is consistent with previously published results. Lisinopril/Hydrochlorothiazide is therefore a valuable therapy in the field of internal medicine. Study of this medication confirmed its efficacy in the treatment of hypertension. CONCLUSION: Control of high blood pressure in our patients according to data was very low, so it is necessary to intensify measures of prevention and treatment. PMID- 27703295 TI - Pulmonary Hypertension - New Trends of Diagnostic and Therapy. AB - Pulmonary hypertension is a pathophysiological state hemodynamically defined as the increase of the mean pulmonary arterial pressure above 25, or 30 mmHg at rest, measured by catheterization of the right heart. Laboratory findings usually reveals polycythemia, the ECG right ventricle hypertrophy, and x-ray characteristic of diseased branches (echocardiography and biomarkers such as B type natriuretic peptide (BNP) and N-terminal pro-BNP hormones are potentially helpful tools in identifying PH). Echocardiography can be found the increase of the right atrium and ventricle, right ventricular hypertrophy, abnormal contraction of the interventricular septum, left ventricular diastolic dysfunction and decreased left ventricular size, with reduced volumes of systole and end diastole. Doppler confirming tricuspid regurgitation. Pharmacological therapy would represent a use: Calcium Channel Blockers, Prostacyclin Analogues, Endothelin Receptor Antagonists and Phosphodiesterase-5 Inhibitors. Alpha adrenergic antagonists, endothelial receptor subtype A (Bosentan, Tracller) with treatment of the underlying disease or anticongestive therapy, are recommended. In case of inadequate response to treatment with a specific drug, guidelines recommend the combined use of drugs from the basic three groups, using their synergism. PMID- 27703296 TI - Rhabdomyolysis in Critically Ill Surgical Patients. AB - INTRODUCTION: Rhabdomyolysis is a syndrome of injury of skeletal muscles associated with myoglobinuria, muscle weakness, electrolyte imbalance and often, acute kidney injury as severe complication. THE AIM: of this study is to detect the incidence of rhabdomyolysis in critically ill patients in the surgical intensive care unit (ICU), and to raise awareness of this medical condition and its treatment among the clinicians. MATERIAL AND METHODS: A retrospective review of all surgical and trauma patients admitted to surgical ICU of the University Surgical Clinic "Mother Teresa" in Skopje, Macedonia, from January 1st till December 31st 2015 was performed. Patients medical records were screened for available serum creatine kinase (CK) with levels > 200 U/l, presence of myoglobin in the serum in levels > 80 ng/ml, or if they had a clinical diagnosis of rhabdomyolysis by an attending doctor. Descriptive statistical methods were used to analyze the collected data. RESULTS: Out of totally 1084 patients hospitalized in the ICU, 93 were diagnosed with rhabdomyolysis during the course of one year. 82(88%) patients were trauma patients, while 11(12%) were surgical non trauma patients. 7(7.5%) patients diagnosed with rhabdomyolysis developed acute kidney injury (AKI) that required dialysis. Average values of serum myoglobin levels were 230 ng/ml, with highest values of > 5000 ng/ml. Patients who developed AKI had serum myoglobin levels above 2000 ng/ml. Average values of serum CK levels were 400 U/l, with highest value of 21600 U/l. Patients who developed AKI had serum CK levels above 3000 U/l. CONCLUSION: Regular monitoring and early detection of elevated serum CK and myoglobin levels in critically ill surgical and trauma patients is recommended in order to recognize and treat rhabdomyolysis in timely manner and thus prevent development of AKI. PMID- 27703297 TI - Primary Central Nervous System Anaplastic Large T-cell Lymphoma. AB - INTRODUCTION: Primary central nervous system lymphoma (PCNSL) of T-cell origin is an exceptionally rare, highly malignant intracranial neoplasm. Although such a tumor typically presents with a focal mass lesion. CASE REPORT: Past medical history of a 26-year-old male patient with a PCNS lymphoma of T-cell origin was not suggestive of intracranial pathology or any disorder of other organs and organic systems. To achieve a gross total tumor resection, surgery was performed via osteoplastic craniotomy using the left frontal transcortical transventricular approach. Histological and immunohistochemical analyses of the tissue removed described tumor as anaplastic large cell lymphoma of T-cells (T-ALCL). Postoperative and neurological recovery was complete, while control imaging of the brain showed no signs of residual tumor at a six-month follow-up. The patient, who did not appear immunocompromized, was referred to a hematologist and an oncologist where corticosteroids, the particular chemotherapeutic protocol and irradiation therapy were applied. CONCLUSION: Since PCNS lymphoma is a potentially curable brain tumor, we believe that proper selection of the management options, including early radical tumor resection for solitary PCNS lymphoma, may be proposed as a major treatment of such a tumor in selected patients, resulting in a satisfactory outcome. PMID- 27703298 TI - Management of the Patient with Aggressive and Resistant Papillary Thyroid Carcinoma. AB - PURPOSE: Papillary carcinoma is the most frequent type of thyroid cancer and was considered the most benign of all thyroid carcinomas, with a low risk of distant metastases. However, there are some variants of papillary thyroid carcinoma that have affinity to spread in many organs, such as: lymph nodes, lungs and bones. AIM: The aim of this study was presentation of a case with papillary carcinoma of the thyroid gland, very persistent and resistant in treatment with I 131. MATERIAL AND RESULTS: A man 56 years old were diagnosed with papillary carcinoma of thyroid gland. He underwent a surgical removal of the tumor and right lobe of thyroid gland. With histopathology examination, were confirmed follicular variant of papillary carcinoma pT4. Two weeks later he underwent total thyroidectomy and was treated with 100 mCi of J 131. Six months later, the value of thyroglobulin was found elevated above upper measured limits (more than 500 ng/ml). Patient underwent surgical removal of 10 metastatic lymph nodes in the left side of the neck and has been treated with 145 mCi of radioiodine I 131. The examination after 5 months shows elevation of thyroglobulin, more than 20000 ng/ml and focally uptake of J 131 in the left lung. Patient was treated once again with 150 mCi radioiodine J 131. Whole body scintigraphy was registered focal uptake of radioiodine in the middle of the left collarbone. After a month, patient refers the enlargement of the lymph node in the right side of the neck. Currently patient is being treated with kinase inhibitor drug sorafenib and ibandronate. We have identified first positive response in treatment. Enlarged lymph node in the neck was reduced and the patient began feeling better. CONCLUSION: This study suggests that some subtypes of papillary thyroid carcinoma appear to have more aggressive biological course. Subtypes of papillary thyroid carcinoma such as diffuse sclerosing carcinoma, tall cell or columnar cell and insular variants, appears to have more aggressive biological course and need early detection and other kind of treatment. PMID- 27703299 TI - Metastasis of Prostate Adenocarcinoma to the Testis. AB - INTRODUCTION: Prostate carcinoma is the most frequently diagnosed carcinoma in the male population. The most typical places of the metastases are pelvic lymphatic glands, bones and lungs, and very rarely it metastasizes into a testis. The prognostic importance of testicular metastasis of prostate cancer is not yet well-known, due to a very few published cases. According to the known facts, it is certain that a metastasis of the prostate carcinoma into a testis is a sign of an advanced disease. CASE REPORT: This work presents a 48-year-old patient, to whom an adenocarcinoma of the prostate has been proven by the pathohistological finding of transrectal biopsy, performed due to the elevated level of prostate specific antigen (PSA). Nine years after the initial diagnosis, due to a gradual rise of PSA and tumorous enlargement of the left testis, left inguinal orchectomy and right orchectomy were performed. Metastatic dissemination of prostate adenocarcinoma into a testis was determined by a pathohistological analysis of the left testis. CONCLUSION: The metastasis of the prostate carcinoma into a testis, as a rare localization of the metastatic dissemination, after additionally performed orchectomy along with further oncological therapy, can provide a continuation of a good life quality as well as a control of the disease in a longer time period. PMID- 27703300 TI - A Modified Wrapping-internal Shunt Method for Hemostasis in Bentall Procedure. AB - INTRODUCTION: Blindly punching between aorta and right atrium is dangerous. In that case, there is concerned about leakage between the two referred isolate parts. Besides, as the routine imaging techniques (echocardiography or computer tomography) are incompetent to detect this particular anatomic structure preoperatively, the intraoperative inspection appears necessary. Our method is useful for identifying this innate fusion plane. CASE REPORT: The thrombosis surrounding prosthesis was detected in the first ultrasound examination after the operation, which was considered to be an indication of successful hemostasis. As the innate fusion between aorta and right atrium appears no rare, the selective creation of left-to-right internal shunt is a valuable maneuver for controlling bleeding in appropriate cases. PMID- 27703301 TI - P-Selectin Targeted Dexamethasone-Loaded Lipid Nanoemulsions: A Novel Therapy to Reduce Vascular Inflammation. AB - Inflammation is a common process associated with numerous vascular pathologies. We hypothesized that targeting the inflamed endothelium by coupling a peptide with high affinity for P-selectin to the surface of dexamethasone-loaded lipid nanoemulsions will highly increase their specific binding to activated endothelial cells (EC) and reduce the cell activation. We developed and characterized dexamethasone-loaded lipid nanoemulsions directed towards P selectin (PLN-Dex) and monitored their anti-inflammatory effects in vitro using cultured EC (EA.hy926 cells) and in vivo using a mouse model of acute inflammation [lipopolysaccharides (LPS) intravenously administered in C57BL/6 mice]. We found that PLN-Dex bound specifically to the surface of activated EC are efficiently internalized by EC and reduced the expression of proinflammatory genes, thus preventing the monocyte adhesion and transmigration to/through activated EC. Given intravenously in mice with acute inflammation, PLN-Dex accumulated at a significant high level in the lungs (compared to nontargeted nanoemulsions) and significantly reduced mRNA expression level of key proinflammatory cytokines such as IL-1beta, IL-6, and MCP-1. In conclusion, the newly developed nanoformulation, PLN-Dex, is functional in vitro and in vivo, reducing selectively the endothelium activation and the consequent monocyte infiltration and diminishing significantly the lungs' inflammation, in a mouse model of acute inflammation. PMID- 27703302 TI - SOCS1 Mimetic Peptide Suppresses Chronic Intraocular Inflammatory Disease (Uveitis). AB - Uveitis is a potentially sight-threatening disease characterized by repeated cycles of remission and recurrent inflammation. The JAK/STAT pathway regulates the differentiation of pathogenic Th1 and Th17 cells that mediate uveitis. A SOCS1 mimetic peptide (SOCS1-KIR) that inhibits JAK2/STAT1 pathways has recently been shown to suppress experimental autoimmune uveitis (EAU). However, it is not clear whether SOCS1-KIR ameliorated uveitis by targeting JAK/STAT pathways of pathogenic lymphocytes or via inhibition of macrophages and antigen-presenting cells that also enter the retina during EAU. To further investigate mechanisms that mediate SOCS1-KIR effects and evaluate the efficacy of SOCS1-KIR as an investigational drug for chronic uveitis, we induced EAU in rats by adoptive transfer of uveitogenic T-cells and monitored disease progression and severity by slit-lamp microscopy, histology, and optical coherence tomography. Topical administration of SOCS1-KIR ameliorated acute and chronic posterior uveitis by inhibiting Th17 cells and the recruitment of inflammatory cells into retina while promoting expansion of IL-10-producing Tregs. We further show that SOCS1-KIR conferred protection of resident retinal cells that play critical role in vision from cytotoxic effects of inflammatory cytokines by downregulating proapoptotic genes. Thus, SOCS1-KIR suppresses uveitis and confers neuroprotective effects and might be exploited as a noninvasive treatment for chronic uveitis.

PMID- 27703303 TI - Regulation of IL-33 by Oncostatin M in Mouse Lung Epithelial Cells. AB - IL-33 modulates both innate and adaptive immune responses at tissue sites including lung and may play critical roles in inflammatory lung disease. Although IL-33 expression can be altered upon NF-Kappa B activation, here we examine regulation by Oncostatin M, a gp130 cytokine family member, in mouse lung tissue. Responses were assessed in BALB/c mouse lung at day 7 of transient overexpression using endotracheally administered adenovirus encoding OSM (AdOSM) or empty vector (AdDel70). Whole lung extracts showed induction of IL-33 mRNA (>20-fold) and protein (10-fold increase in immunoblots) by AdOSM relative to AdDel70. Immunohistochemistry for IL-33 indicated a marked induction of nuclear staining in alveolar epithelial cells in vivo. Oncostatin M stimulated IL-33 mRNA and IL 33 full length protein in C10 mouse type 2 alveolar epithelial cells in culture in time-dependent and dose-dependent fashion, whereas IL-6, LIF, IL-31, IL-4, or IL-13 did not, and TGFbeta repressed IL-33. IL-33 induction was associated with activation of STAT3, and pharmacological inhibition of STAT3 ameliorated IL-33 levels. These results indicate Oncostatin M as a potent inducer of IL-33 in mouse lung epithelial cells and suggest that an OSM/IL-33 axis may participate in innate immunity and inflammatory conditions in lung. PMID- 27703306 TI - p27KIP1 loss promotes proliferation and phagocytosis but prevents epithelial mesenchymal transition in RPE cells after photoreceptor damage. AB - PURPOSE: p27KIP1 (p27), originally identified as a cell cycle inhibitor, is now known to have multifaceted roles beyond cell cycle regulation. p27 is required for the normal histogenesis of the RPE, but the role of p27 in the mature RPE remains elusive. To define the role of p27 in the maintenance and function of the RPE, we investigated the effects of p27 deletion on the responses of the RPE after photoreceptor damage. METHODS: Photoreceptor damage was induced in wild type (WT) and p27 knockout (KO) mice with N-methyl-N-nitrosourea (MNU) treatment. Damage-induced responses of the RPE were investigated with bromodeoxyuridine (BrdU) incorporation assays, immunofluorescence, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assays at different stages after MNU treatment. Subcellular localization of p27 in the WT RPE was also analyzed in vivo and in vitro. RESULTS: MNU treatment induced photoreceptor-specific degeneration in the WT and KO retinas. BrdU incorporation assays revealed virtually no proliferation of RPE cells in the WT retinas while, in the KO retinas, approximately 16% of the RPE cells incorporated BrdU at day 2 after MNU treatment. The RPE in the KO retinas developed aberrant protrusions into the outer nuclear layer in response to photoreceptor damage and engulfed outer segment debris, as well as TUNEL-positive photoreceptor cells. Increased phosphorylation of myosin light chains and their association with rhodopsin positive phagosomes were observed in the mutant RPE, suggesting possible deregulation of cytoskeletal dynamics. In addition, WT RPE cells exhibited evidence of the epithelial-mesenchymal transition (EMT), including morphological changes, induction of alpha-smooth muscle actin expression, and attenuated expression of tight junction protein ZO-1 while these changes were absent in the KO retinas. In the normal WT retinas, p27 was localized to the nuclei of RPE cells while nuclear and cytoplasmic p27 was detected in RPE cells undergoing EMT, suggesting a role for cytoplasmic p27 in the phenotype changes of RPE cells. CONCLUSIONS: p27 loss promoted proliferation and phagocytic activity of RPE cells while preventing EMT after photoreceptor damage. These findings provide evidence for the role of p27 in the control of RPE responses to retinal damage. PMID- 27703307 TI - Effect of alpha lipoic acid on retinal ganglion cell survival in an optic nerve crush model. AB - PURPOSE: This study was conducted to determine whether alpha lipoic acid (ALA) promotes the survival of retinal ganglion cells (RGCs) in a rat model of optic nerve crush (ONC) injury and to investigate the neuroprotective mechanisms of ALA in the retina in this ONC injury model. METHODS: Adult male Sprague-Dawley rats (180-220 g) were subjected to ONC injury surgery. ALA (63 mg/kg) was injected intravenously 1 day before or after the ONC injury. Animals were euthanized after 10 days, and the number of ganglion cells positive for RNA-binding protein with multiple splicing (Rbpms), which is an RGC marker, were counted on the whole mount retinas. In addition, immunofluorescence and immunoblotting were performed to examine the localization and levels of erythropoietin receptor (EPOR) and neurotrophin-4/5 (NT4/5) in the retinas in all experimental groups. To determine whether the EPO/EPOR signaling pathway was involved in the ALA antioxidant pathway, the rats were subjected to ruxolitinib (INCB018424, 0.25 mg/kg, bid, intraperitoneal, i.p.) treatment after the animals were injected intravenously with ALA 1 day before ONC injury. RESULTS: The average number of Rbpms-positive cells/mm2 in the control group (sham-operated group), the ONC group, the ALA-ONC group, and the ONC-ALA group retinas was 2219+/-28, 418+/-8, 848+/-22, and 613+/ 18/mm2, respectively. The ALA-ONC and ONC-ALA groups showed a statistically significantly increased RGC survival rate compared to the ONC group. There were statistical differences in the RGC survival rates between the ALA-ONC (39%) and ONC-ALA groups (28%; p<0.05). Immunofluorescent labeling showed that EPOR and NT4/5 expression was significant in the retinal ganglion cell layer (GCL). At the same time, western blot analysis revealed that ALA induced upregulation of EPOR protein and NT4/5 protein expression in the retina after ONC injury. However, INCB018424 reversed the protective effects of ALA on the ONC retinas. CONCLUSIONS: ALA has neuroprotective effects on RGCs after ONC injury. Moreover, prophylactic administration of ALA may have a stronger neuroprotective effect against ONC-induced damage. Based on these data, we also conclude that the endogenous EPO/EPOR signaling pathway may contribute to the protective effects of ALA in the retina after ONC injury.

AB - BACKGROUND: Situs inversus totalis (SIT), a rare congenital anomaly, is characterized by a complete mirror image transposition of the thoracic and abdominal viscera. We report the case of a 66-year-old woman with SIT who was diagnosed with gastric antral carcinoma. Curative distal gastrectomy with Billroth-I anastomosis was performed. Description of the case: A 66-year-old woman visited our outpatient department complaining of abdominal pain in the left upper quadrant for about one year. Physical examination revealed that the apex beat was in the right fifth intercostal space, just at the midclavicular line while a soft systolic murmur was audible at the upper right sternal border. The abdominal examination was unremarkable. The preoperative diagnosis was confirmed by gastroscopy and biopsy. Preoperative echocardiogram revealed the presence of dextrocardia and atrial septal defect. Preoperative contrasted computed tomography showed a complete right-left reversal of the thoracic and abdominal organs and thickened wall of gastric antrum without distant metastasis. Laparotomy through a midline incision confirmed the complete mirror-image transposition of the abdominal visceral organs and a 4-cm tumor with serosal involvement at the gastric antrum. Curative distal gastrectomy with D2 lymphadenectomy and Billroth-I anastomosis was performed. The patient had a rapid recovery and was discharged without any complications. The final staging of this case was pT4aN1M0, stage IIIa and she received chemotherapy with the SOX regimen for three cycles. Fifteen months after the operation, the patient is alive without any signs of recurrence. CONCLUSIONS: The incidence of gastric cancer with SIT is very rare. Appropriate diagnostic modalities are very helpful for the diagnosis and preoperative planning. Gastrectomy with D2 lymphadenectomy in patients with SIT can be performed successfully with sufficient preoperative evaluation, comprehensive knowledge of anatomy, and meticulous surgical manipulation. Caution should be given to the possibility of coexisting cardiopulmonary malformations and synchronous cancers. Hippokratia 2015; 19 (4): 360-362. PMID- 27703310 TI - "Bath Salts" intoxication with multiorgan failure and left-sided ischemic colitis: a case report. AB - BACKGROUND: In the recent years, a new group of designer drugs, under the brand name of bath salts has emerged as a new trend. They are mainly b-ketone amphetamine analogs and are derivatives of cathinone, a monoamine alkaloid. They are abused for psychostimulant effects. Their primary ingredient 3,4 methylenedioxypyrovalerone (MDPV), has alerted authorities worldwide due to its severe physiological and behavioral toxicities. Description of Case:We present the case of a 47-year-old man with coma, seizures, multi-organ failure and ischemic colitis after intoxication with bath salts containing MDPV. After supportive care, he had a successful outcome. To our knowledge, this report is the first to describe ischemic colitis after MDPV intoxication. Clinicians need to be especially alert since MDPV is not detected by routine screens, and its overdose can be life-threatening. CONCLUSION: Ischemic colitis should be recognized as a potential complication of bath salts ingestion in order to prevent unnecessary interventions, such as diagnostic laparotomy, which could worsen patient's condition.

AB - PURPOSE: A hallmark of retinal gliosis is the increased detection and modification of the type III intermediate filament (IF) proteins vimentin and glial fibrillary acidic protein (GFAP). Here, we investigated vimentin and GFAP in Muller glia in a mouse model of alkali injury, focusing on the posttranslational modification of citrullination. METHODS: Mice were injured by corneal exposure to 1.0 N NaOH, and eyes were enucleated at different time points following injury. The levels of soluble and cytoskeletal forms of IF proteins and citrullination were measured using western blot analysis. Citrullinated GFAP was identified by immunoprecipitation followed by two-dimensional (2D) isoelectric focusing-polyacrylamide gel electrophoresis (IEF-PAGE) western blotting using a specific antibody that recognizes citrullinated GFAP. Vimentin, GFAP, and citrullinated proteins were localized in the retina by immunohistochemistry (IHC). Drug treatments were investigated in retinal explant cultures of posterior eyecups obtained from mouse eyes that were injured in vivo. RESULTS: Detection of GFAP in injured retinas increased over a period of 1 to 7 days, showing increased levels in both soluble and cytoskeletal forms of this IF protein. The global level of citrullinated proteins was also induced over this period, with low-salt buffer extraction showing the most abundant early changes in citrullination. Using IHC, we found that GFAP filaments assembled at Muller glial end feet, growing in size with time through the inner layers of the retina at 1-3 h postinjury. Interestingly, over this early time period, levels of soluble citrullinated proteins also increased within the retina, as detected by western blotting, coincident with the localization of the citrullinated epitopes on growing GFAP filaments and existing vimentin filaments by 3 h after injury. Taking advantage of the in vivo injury model to promote a robust gliotic response, posterior eyecups from 7-day postinjured eyes were treated in explant cultures with the peptidyl arginine deiminase inhibitor Cl-amidine, which was found to reduce global citrullination. Surprisingly, the detection of injury induced high-molecular-weight GFAP species containing citrullinated epitopes was also reduced by Cl-amidine treatment. Using a low dose of the potent type III IF drug withaferin A (WFA), we showed that Cl-amidine treatment in combination with WFA reduced global protein citrullination further, suggesting that GFAP may be a key component of pathological citrullinated targets. CONCLUSIONS: Our findings illuminate citrullination as a potential novel target for trauma-induced retinal gliosis. We also propose that strategies for combining drugs targeting type III IFs and citrullination may potentiate tissue repair, which is an idea that needs to be validated in vivo. PMID- 27703311 TI - Multi-digit contracture release using medial sural artery perforator flap with syndactylization-desyndactylization method. AB - BACKGROUND: The medial sural artery perforator flap, with a long pedicle, has tremendous potential for applications in a variety of soft tissue defects. It can be used for reconstruction of multi-digit contractures of the palmar region. MATERIALS AND METHODS: We present herein the key features of the management of postburn multi-digit volar contractures, using medial sural artery perforator flaps with the syndactylization and desyndactylization method. We describe the use of the free medial sural artery perforator flap in two patients, to reconstruct complex composite hand defects including the second, third, fourth and fifth digits following thermal burns. RESULTS: Both flaps healed uneventfully. In both patients, the hand contractures released completely and adequate joint motion was achieved after a 3-month period of physiotherapy. CONCLUSIONS: The thin medial sural artery perforator flap permits high accuracy of soft tissue reconstruction of the hand and reduces the morbidity at the donor site. The MSAPF is a useful flap in areas such as the hands, in the case of soft tissue deficiency and tendon exposition. Hippokratia 2015; 19 (4): 366-368. PMID- 27703312 TI - Alphan uncommon coexistence of primary sexual, cough and exercise headaches: the first three cases from Greece. AB - BACKGROUND: The "other primary headaches" encompasses a group of uncommon but distinct headache disorders. The coexistence of their subforms such as primary sexual and exercise headache is not a new phenomenon, but in association with cough headache is rather uncommon. Report of cases: We report three cases with a rare coexistence of primary cough, exercise and associated with sexual activity headache. Indomethacin was effective in all patients. The leading pathophysiological explanation involves a rapid rise in intra-abdominal pressure exertional factors or an inappropriate reaction in the cerebral vasculature. CONCLUSIONS: Further studies are needed to confirm a common pathogenic mechanism in these patients. Tauhe coexistence of these headaches needs to be taken into account in the final classification that is expected to be available in 2016. Hippokratia 2015; 19 (4): 369-371. PMID- 27703313 TI - An unusual case of Streptococcus agalactiae meningitis in a patient with sys temic lupus erythematosus. AB - BACKGROUND: Streptococcus agalactiae (group B Streptococcus) is a major cause of sepsis and meningitis in neonates and an important cause of invasive disease in adults. CASE DESCRIPTION: We describe an unusual case of fatal bacterial meningitis caused by Streptococcus agalactiae in a young man suffering from systemic lupus erythematosus for over 20 years. The young man was transferred intubated in AHEPA University Hospital in a coma; twenty-four hours upon arrival and despite intense invasive treatment, he died from multiple organ failure. CONCLUSION: The risk of serious infections in patients with systemic lupus erythematosus even under treatment with moderate doses of corticosteroids is high. Hippokratia 2015; 19 (4):372-373. PMID- 27703314 TI - A rare case of Guillain-Barre syndrome presenting with abdominal pain. AB - BACKGROUND: Guillain-Barre syndrome (GBS) is a heterogeneous condition that encompasses acute immune-mediated polyneuropathies. GBS is the most frequent cause of acute neuromuscular paralysis worldwide and constitutes one of the most serious emergencies in neurology. Description of case: As it presents extremely rarely with the first symptom being abdominal pain, herein we report the case of a 48-year-old man who presented with acute abdominal pain and diagnosed with GBS. The patient required mechanical ventilation for two weeks and was discharged one month later, after having had a tracheostomy and developed tetraplegia. CONCLUSION: GBS should be included in the differential diagnosis of acute abdominal pain when other medical or surgical causes have been excluded. Hippokratia 2015; 19 (4): 374-375.

AB - PURPOSE: To analyze intraocular lens (IOL) orientation data from an online toric back-calculator (astigmatismfix.com) for determining if differences were apparent by lens type. METHODS: A retrospective review of astigmatismfix.com toric back calculations that included IOL identification and intended orientation axis. RESULTS: Of 12,812 total validated calculation records, 8,229 included intended orientation and lens identification data. Of the latter, 5,674 calculations (69%) involved lenses oriented 5 degrees or more from their intended position. Using estimated toric lens usage data, the percentage of lenses with orientation >=5 degrees from intended was 0.89% overall, but the percentage varied significantly between specific toric lens brands (P<0.05). The percentage of back-calculations related to lenses that were not oriented as intended was also statistically significantly different by lens brand (P<0.05). When IOLs were misoriented, they were significantly more likely to be misoriented in a counterclockwise direction (P<0.05). This was found to be due to a bias toward counterclockwise orientation observed with one specific brand, a bias that was not observed with the other three brands analyzed here. CONCLUSION: The percentage of eyes with lens orientation >=5 degrees from intended in the Toric Results Analyzer data set was <1% of toric IOLs in general, with the relative percentage of Tecnis(r) Toric IOLs significantly higher than AcrySof(r) Toric IOLs. Both of these had higher rates than the Staar(r) Toric and Trulign(r) Toric lenses, with the availability of higher Tecnis and AcrySof cylinder powers a likely contributing factor. The AcrySof Toric IOL appears to be less likely than the Tecnis Toric IOL to cause residual astigmatism as a result of misorientation. The Tecnis Toric IOL appears more likely to be misoriented in a counterclockwise direction; no such bias was observed with the AcrySof Toric, the Trulign(r) Toric, or the Staar Toric IOLs. PMID- 27703324 TI - Preservative-free bimatoprost 0.03%/timolol 0.5% fixed combination in patients with glaucoma in clinical practice. AB - PURPOSE: The aim of this study was to evaluate the efficacy and tolerability of, and compliance to, preservative-free (PF), fixed-combination (FC) bimatoprost 0.03%/timolol 0.5% in patients with primary open-angle glaucoma or ocular hypertension in a clinical practice setting. PATIENTS AND METHODS: This open label study observed patients switched to PF FC bimatoprost 0.03%/timolol 0.5% due to insufficient intraocular pressure (IOP) control on previous therapies. IOP was measured at baseline and at ~12 weeks. Tolerability and continuation of therapy were also assessed. RESULTS: A total of 1,553 patients were included in the study, and the per-protocol population comprised 1,391 patients. There were some minor deviations from protocol: some patients with no prior therapy and some who switched for reasons other than insufficient IOP control were included in the analysis. The mean IOP was reduced by 27.4%, from 22.2 mmHg to 16.1 mmHg. In subgroup analyses, the mean IOP was significantly reduced from baseline, irrespective of whether previous treatment was monotherapy or combination therapy, and preserved or PF therapy. Physicians mostly (88.1%) reported the IOP lowering efficacy of PF FC bimatoprost 0.03%/timolol 0.5% to be as expected or better than expected. Switching to PF FC bimatoprost 0.03%/timolol 0.5% resulted in reductions from baseline in the number of patients reporting ocular symptoms. Adverse events were reported by 6.2% of patients, the most common being eye irritation (1.6%) and eye pruritus (1.0%). Physicians reported treatment compliance as better or unchanged compared with prior treatment in almost all patients (93.9%). Most patients were expected to continue PF FC bimatoprost 0.03%/timolol 0.5% after the end of the study. CONCLUSION: Switching to PF FC bimatoprost 0.03%/timolol 0.5% was associated with significant IOP reductions from baseline over 12 weeks. Adverse events were uncommon, and compliance was high compared with previous therapy. PF FC bimatoprost 0.03%/timolol 0.5% may be a suitable treatment for patients with inadequately controlled IOP or who are sensitive to preservatives. PMID- 27703325 TI - A comparison of pop and chop to divide and conquer in resident cataract surgery. AB - In this randomized prospective study, the cumulative dissipated energy and case time of pop and chop and of traditional four-quadrant divide and conquer in the first 60 cases (in total 120 eyes) of cataract surgery performed by two residents at the Veterans Administration Hospital in Hampton, Virginia, were compared. Overall and individually, the residents had significantly shorter case times and used significantly less cumulative dissipated energy for performing pop and chop than that for divide and conquer technique. There was no difference in complication rates or visual outcomes between these two techniques. The results of this study suggest that pop and chop is a more time- and energy-efficient method of nucleofractis than divide and conquer for novice resident surgeons. PMID- 27703326 TI - Intravitreal ziv-aflibercept for macular edema following retinal vein occlusion. AB - AIM: To report the efficacy of intravitreal ziv-aflibercept injections in eyes with macular edema due to retinal vein occlusions (RVOs). METHODS: Consecutive patients with persistent or recurrent macular edema (central macula thickness >250 MUm) due to RVO were enrolled in this prospective study. Study eyes received intravitreal injections of ziv-aflibercept (1.25 mg/0.05 mL) at baseline. Patients were reassessed monthly for 4 months and given additional injections pro re nata for worsening best-corrected visual acuity (BCVA), intraretinal edema or subretinal fluid seen on spectral domain optical coherence tomography, or central macular thickness (CMT) measurements >250 MUm. The primary endpoint was improvement in mean CMT at 4 months. Secondary endpoints included improvement in mean BCVA, and ocular and systemic safety signals. RESULTS: Nine eyes (five central and four branch RVOs) of nine patients were enrolled. The mean +/- standard deviation CMT decreased from 604+/-199 MUm at baseline to 319+/-115 MUm (P=0.001) at 1 month and to 351+/-205 MUm (P=0.026) at 4 months. The mean BCVA did not improve significantly from baseline (1.00 LogMAR) to the 1-month (0.74 LogMAR; P=0.2) and 4-month (0.71 LogMAR; P=0.13) visits. No safety signals were noted. CONCLUSION: In this small prospective study, intravitreal ziv-aflibercept significantly improved mean CMT in eyes with persistent or recurrent macular edema due to RVOs. Prospective, randomized trials comparing ziv-aflibercept with standard pharmacotherapy are needed to better define efficacy and safety. PMID- 27703328 TI - Effect of low dose of intrathecal pethidine on the incidence and intensity of shivering during cesarean section under spinal anesthesia: a randomized, placebo controlled, double-blind clinical trial. AB - INTRODUCTION: Shivering is among the unpleasant and potentially harmful side effects of spinal anesthesia. The aim of this randomized double-blind clinical trial was to compare the antishivering effect of two different doses of intrathecal pethidine on the incidence and intensity of shivering and other side effects in patients who underwent cesarean section. METHODS: In this study, 150 parturient females scheduled for nonemergent cesarean section were randomly allocated to three groups. Spinal anesthesia was performed with 0.5% hyperbaric bupivacaine (12.5 mg), plus 0.5 mL of 0.9% saline in the standard group (S group), and the same dose of bupivacaine with 5 mg (P5 group) or 10 mg of pethidine (P10 group). Demographic and surgical data, incidence and intensity of shivering (primary outcome), hemodynamic indices, forehead and core temperatures, maximum sensory level, Apgar scores, and adverse events were evaluated by a blinded observer. RESULTS: There were no significant differences between the three study groups regarding the demographic and surgical data, hemodynamic indices, core temperatures, and maximum sensory level (P>0.05). The incidence and intensity of shivering were significantly less in the P5 and P10 groups (P<0.001) when compared with the S group. There were no significant differences between groups for secondary outcomes, except pruritus, which was more common in the P5 and P10 groups when compared with the S group (P=0.01). CONCLUSION: Low dose of intrathecal pethidine is safe, and can decrease the incidence and intensity of shivering during cesarean section, without having major side effects. PMID- 27703327 TI - Eag1 channels as potential early-stage biomarkers of hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is a major cause of cancer death worldwide. HCC is usually asymptomatic at potential curative stages, and it has very poor prognosis if detected later. Thus, the identification of early biomarkers and novel therapies is essential to improve HCC patient survival. Ion channels have been proposed as potential tumor markers and therapeutic targets for several cancers including HCC. Especially, the ether a-go-go-1 (Eag1) voltage-gated potassium channel has been suggested as an early marker for HCC. Eag1 is overexpressed during HCC development from the cirrhotic and the preneoplastic lesions preceding HCC in a rat model. The channel is also overexpressed in human HCC. Astemizole has gained great interest as a potential anticancer drug because it targets several proteins involved in cancer including Eag1. Actually, in vivo studies have shown that astemizole may have clinical utility for HCC prevention and treatment. Here, we will review first some general aspects of HCC including the current biomarkers and therapies, and then we will focus on Eag1 channels as promising tools in the early diagnosis of HCC. PMID- 27703329 TI - Bulgecin A as a beta-lactam enhancer for carbapenem-resistant Pseudomonas aeruginosa and carbapenem-resistant Acinetobacter baumannii clinical isolates containing various resistance mechanisms. AB - Genetic screening of Pseudomonas aeruginosa (PSDA) and Acinetobacter baumannii (ACB) reveals genes that confer increased susceptibility to beta-lactams when disrupted, suggesting novel drug targets. One such target is lytic transglycosylase. Bulgecin A (BlgA) is a natural product of Pseudomonas mesoacidophila and a lytic transglycosolase inhibitor that works synergistically with beta-lactams targeting PBP3 for Enterobacteriaceae. BlgA also weakly inhibits di-Zn2+ metallo-beta-lactamases like L1 of Stenotrophomonas maltophilia. We hypothesized that because of its unique mechanism of action, BlgA could restore susceptibility to carbapenems in carbapenem-resistant PSDA (CR-PSDA) and carbapenem-resistant ACB, as well as ACB resistant to sulbactam. A BlgA containing extract was prepared using a previously published protocol. CR-PSDA clinical isolates demonstrating a variety of carbapenem resistance mechanisms (VIM-2 carbapenemases, efflux mechanisms, and AmpC producer expression) were characterized with agar dilution minimum inhibitory concentration (MIC) testing and polymerase chain reaction. Growth curves using these strains were prepared using meropenem, BlgA extract, and meropenem plus BlgA extract. A concentrated Blg A extract combined with low concentrations of meropenem, was able to inhibit the growth of clinical strains of CR-PSDA for strains that had meropenem MICs >=8 mg/L by agar dilution, and a clinical strain of an OXA-24 producing ACB that had a meropenem MIC >32 mg/L and intermediate ampicillin/sulbactam susceptibility. Similar experiments were conducted on a TEM-1 producing ACB strain resistant to sulbactam. BlgA with ampicillin/sulbactam inhibited the growth of this organism. As in Enterobacteriaceae, BlgA appears to restore the efficacy of meropenem in suppressing the growth of CR-PSDA and carbapenem-resistant ACB strains with a variety of common carbapenem resistance mechanisms. BlgA extract also inhibits VIM-2 beta-lactamase in vitro. BlgA may prove to be an exciting adjunctive compound to extend the life of carbapenems against these vexing pathogens. PMID- 27703330 TI - Comparisons of the pharmacokinetics and tolerability of fixed-dose combinations of amlodipine besylate/losartan and amlodipine camsylate/losartan in healthy subjects: a randomized, open-label, single-dose, two-period, two-sequence crossover study. AB - BACKGROUND: A fixed-dose combination (FDC) of amlodipine and losartan has been used to reduce blood pressure in patients whose hypertension is not sufficiently controlled with either drug alone. The aim of this study was to evaluate the pharmacokinetic (PK) characteristics and tolerability of an FDC of 6.94 mg amlodipine besylate (5 mg as amlodipine)/50 mg losartan potassium compared to an FDC of 5 mg amlodipine camsylate/50 mg losartan potassium in healthy subjects. SUBJECTS AND METHODS: A randomized, open-label, single-dose, two-period, two sequence crossover study was conducted on 46 healthy male subjects. Blood concentrations were measured by liquid chromatography-tandem mass spectrometry. Blood samples were collected up to 144 hours post dose for each period. PK parameters were calculated in each treatment group using a noncompartmental method. The 90% confidence intervals (CIs) of the geometric mean ratios of the two treatments for the maximum plasma concentration (Cmax) and the area under the concentration curve from time zero to the last quantifiable time point (AUC0-t) were estimated. Tolerability assessments were performed for all subjects who received the drug at least once. RESULTS: The PK profiles of the two treatments were similar. For amlodipine, the geometric mean ratios (90% CIs) of amlodipine besylate to amlodipine camsylate for the Cmax and AUC0-t were 0.98 (0.94-1.01) and 0.97 (0.93-1.01), respectively. The corresponding values for losartan were 0.91 (0.81-1.02) and 1.05 (0.98-1.12), respectively. The incidence of adverse events was not significantly different between the two treatments, and both were well tolerated. CONCLUSION: An FDC of 6.94 mg amlodipine besylate (5 mg as amlodipine)/50 mg losartan potassium produced similar results to an FDC of 5 mg amlodipine camsylate/50 mg losartan potassium treatment with respect to the PK parameters of amlodipine and losartan based on Cmax and AUC0-t values. The amlodipine besylate/losartan potassium combination was well tolerated by healthy male subjects. PMID- 27703331 TI - The spice for joint inflammation: anti-inflammatory role of curcumin in treating osteoarthritis. AB - Osteoarthritis is a degenerative disease of the joint affecting aging populations worldwide. It has an underlying inflammatory cause, which contributes to the loss of chondrocytes, leading to diminished cartilage layer at the affected joints. Compounds with anti-inflammatory properties are potential treatment agents for osteoarthritis. Curcumin derived from Curcuma species is an anti-inflammatory compound as such. This review aims to summarize the antiosteoarthritic effects of curcumin derived from clinical and preclinical studies. Many clinical trials have been conducted to determine the effectiveness of curcumin in osteoarthritic patients. Extracts of Curcuma species, curcuminoids and enhanced curcumin, were used in these studies. Patients with osteoarthritis showed improvement in pain, physical function, and quality of life after taking curcumin. They also reported reduced concomitant usage of analgesics and side effects during treatment. In vitro studies demonstrated that curcumin could prevent the apoptosis of chondrocytes, suppress the release of proteoglycans and metal metalloproteases and expression of cyclooxygenase, prostaglandin E-2, and inflammatory cytokines in chondrocytes. These were achieved by blocking the activation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) system in the chondrocytes, by preventing the activation of nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha, phosphorylation, and translocation of the p65 subunit of NF-kappaB complexes into the nucleus. In conclusion, curcumin is a potential candidate for the treatment of osteoarthritis. More well-planned randomized control trials and enhanced curcumin formulation are required to justify the use of curcumin in treating osteoarthritis.

AB - Bioactive mediators, cytokines, and chemokines have an important role in regulating and optimizing the synergistic action of materials, cells, and cellular microenvironments for tissue engineering. RADA self-assembling peptide hydrogels have been proved to have an excellent ability to promote cell proliferation, wound healing, tissue repair, and drug delivery. Here, we report that D-RADA16 and L-RADA16-RGD self-assembling peptides can form stable second structure and hydrogel scaffolds, affording the slow release of growth factor (transforming growth factor cytokine-beta 1 [TGF-beta 1]). In vitro tests demonstrated that the plateau release amount can be obtained till 72 hours. Moreover, L-RADA16, D-RADA16, and L-RADA16-RGD self-assembling peptide hydrogels containing TGF-beta 1 were used for 3D cell culture of bone mesenchymal stem cells of rats for 2 weeks. The results revealed that these three RADA16 peptide hydrogels had a significantly favorable influence on proliferation of bone mesenchymal stem cells and hold some promise in slow and sustained release of growth factor. PMID- 27703333 TI - Satisfaction and associated factors of outpatient psychiatric service consumers in Ethiopia. AB - PURPOSE: The purpose of this study was to assess the level of patient satisfaction and associated factors with psychiatric outpatient services in Ethiopia. PATIENTS AND METHODS: A cross-sectional study was performed from May 2015 to June 2015. A total of 454 participants selected by systematic random sampling were included in this study. Pretested and interviewer-administered questionnaire was used to collect the data. Patient satisfaction was measured using Charleston Psychiatric Outpatient Satisfaction Scale, and other validated tools were used to assess the associated variables. Multivariate logistic regressions with 95% confidence interval (CI) were used to assess the strength, and P-value <0.05 was used to indicate significance of association. RESULTS: A total of 441 respondents were enrolled, with a response rate of 97.1% and magnitude of satisfaction of 61.2%. Being male (adjusted odds ratio [AOR] =0.612, 95% CI: 0.39, 0.94), being widowed (AOR =0.13, 95% CI: 0.05, 0.36), urban residence (AOR =0.49, 95% CI: 0.31, 0.78), diagnosed with schizophrenia (AOR =0.48, 95% CI: 0.28, 0.81), unfavorable attitude (AOR =0.49, 95% CI: 0.28, 0.86), and poor social functioning (AOR =0.52, 95% CI: 0.34, 0.80) were significantly associated with satisfaction. CONCLUSION: More than one-third of psychiatric service consumers were dissatisfied with the service they received. Integrating patients to their own treatment plan and regular service evaluation are important to improve satisfaction. PMID- 27703334 TI - Patients' attitudes to the use of modern technologies in the treatment of diabetes. AB - BACKGROUND: The incidence of diabetes is rising across the world. This global problem significantly affects the economic and social development in the 21st century. If the disease is diagnosed in time, the number of complications as well as the costs of therapy will be lower. Modern technologies permeate all spheres of medicine, and diabetes treatment is no exception. Therefore, the aim of this article is to analyze patients' attitudes to the use of modern technologies in the treatment of diabetes (type 1 diabetes mellitus [T1DM] and type 2 diabetes mellitus [T2DM]). METHODS: A total of 313 respondents from the Czech Republic in the period from June 24, 2015, to July 24, 2015, participated in a questionnaire survey. The target group was diabetics regardless of the type of illness. Collected data were analyzed using descriptive statistical methods, Z-test, and test of independence (Pearson's chi-squared test). RESULTS: Although in other areas mobile applications are used to monitor patients' health condition in ~30% of cases, in the case of diabetes they are used by only 4% of respondents. Approximately 8% of participants use an application, but they do not like it. The rest of the respondents have never used any mobile application. These low figures are due to a lack of knowledge about the availability and possibilities of mobile applications. A positive correlation was proven between technical skills and methods of entering data. Gender and age show only a weak dependency of the method of writing data on their own health condition. Furthermore, the monitored parameters show that patients with T1DM control and know more about their health condition than patients with T2DM, which is reflected, for example, by more frequent blood glucose measurements or larger track of their physical activity. Conversely, the relationship between the associated complications and self-care activities has not been demonstrated. CONCLUSION: Despite the current fast development of modern technologies, these technologies are not frequently used in treating patients. The principal problem lies in patients' low technological knowledge and their higher age, which makes learning new skills, including the use of modern technologies, more difficult. PMID- 27703335 TI - Evaluation of factors associated with psychiatric patient dropout at a university outpatient clinic in Japan. AB - BACKGROUND: Patient dropout from treatment can lead to a deterioration in clinical condition, thereby increasing the need for more intensive therapy that incurs substantial social and economic losses. The aim of this study was to identify factors related to psychiatric patient dropout at a university outpatient clinic in Japan. METHODS: We retrospectively examined the medical charts of new psychiatric patients who were diagnosed with either a mood disorder (International Classification of Diseases, 10th revision, code: F3) or an anxiety disorder (F4) in the outpatient clinic at Kyoto Prefectural University of Medicine Hospital in Kyoto, Japan, between April 2010 and March 2013. The baseline characteristics of the patients (age, sex, Global Assessment of Functioning score, Clinical Global Impression-Severity of Illness score, education, occupation, marital status, duration of treatment, and prior treatment history), treating psychiatrist experience in years, and sex concordance between the patients and their treating psychiatrists were analyzed using Cox regression models. RESULTS: From among 1,626 eligible new patients during the study period, 532 patients were enrolled in the study (F3: n=176; F4: n=356). The dropout rate was 35.7%, which was similar to that of previous studies. Higher educational level, being married, and lower Global Assessment of Functioning scores were associated with a lower dropout rate. Although psychiatrist experience was not significantly associated with patient dropout in the multivariate analysis, patients treated by less experienced psychiatrists had a higher hazard ratio for dropout (1.31; 95% confidence interval: 0.94-1.85). CONCLUSION: In order to reduce the dropout rate, special focus should be placed on patients with the factors identified in this study, and young psychiatrists should undergo further education to foster adherence. PMID- 27703336 TI - Profile of the capsaicin 8% patch for the management of neuropathic pain associated with postherpetic neuralgia: safety, efficacy, and patient acceptability. AB - Capsaicin is a naturally occurring irritant active ingredient found in hot peppers. It is a ligand for transient receptor potential channel vanilloid receptors, which are found in nociceptive nerve terminals in the skin. Initial exposure to topical capsaicin leads to excitation of these receptors, release of vasoactive mediators, erythema, intense burning, pain, and thereafter desensitization of sensory neurons resulting in inhibition of pain transmission. Capsaicin 8% has been licensed for the treatment of postherpetic neuralgia pain in recent years. A single application of high-concentration capsaicin for 60 minutes for postherpetic neuralgia has been robustly evaluated. Capsaicin 8% patches are applied to the most painful areas of healthy skin and allowed to remain for 60 minutes. Treatment can be repeated every 90 days if the pain persists or returns. The patches are usually applied in specialist pain clinics where patients can be pretreated and monitored. Health care staff need to take certain precautions before administering these patches to avoid unintentional contact. Common adverse effects of the capsaicin 8% patch are transient mild-to moderate self-limiting application-site burning, pain, erythema, pruritus, papules, swelling, dryness, and hypertension. To manage local pain from capsaicin application, the skin is pretreated with a local anesthetic such as topical lidocaine or an oral analgesic such as oxycodone for up to 5 days. A transient increase in pain is usually seen within 48 hours of patch application before the pain-relieving effect starts. Systemic absorption is minimal and clinically insignificant. The nature of administration and relatively high cost of capsaicin patches can significantly limit their use to a small number of patients with severe refractory symptoms. This review highlights recent evidence related to the use and effectiveness of the 8% capsaicin patch for Postherpetic Neuralgia and discusses its safety and side-effect profiles. PMID- 27703337 TI - Patient expectations and their satisfaction in the context of public hospitals. AB - BACKGROUND: Patient expectations have been recognized as a factor for patient satisfaction in medical consultations. Although various studies explored the relationship between patient expectations and patient satisfaction in developed countries, there is a lack of research evidence in Ethiopia where the meeting of patient expectations could relate to satisfaction. OBJECTIVE: To assess the relationship between patients' expectations and their satisfaction in the consultation of patients at the outpatient department. STUDY DESIGN: Data were collected regarding preconsultation expectations and postconsultation experiences of adult patients attending nine public hospitals. A systematic random sampling method was used where every fifth patient attending an outpatient department was selected. The patients were interviewed before consultation and after consultation to assess whether their pre-consultation expectations were met and to assess how satisfied they were with the consultation. Cronbach's alpha statistic was used to assess the reliability of the expectation questionnaires, and paired t-test was used to assess any differences between previsit expectations and postvisit experiences. Logistic regression techniques were used to assess variables considered as independent factors for patient satisfaction. RESULTS: A total of 776 patients were interviewed, giving a response rate of 92.3%. About 93.7% mentioned a diagnosis for their condition as a reason for their current hospital visits. There is a significant difference between preconsultation expectation and postconsultation expectation. Postconsultation expectation, perceived health status, and perceived control on health were factors identified as increasing patient satisfaction. In addition, the presence of any disappointments or worries, previous experience in health care, and extent of influence on the consultation had a negative influence on satisfaction. CONCLUSION: Postconsultation expectation impacts patient satisfaction. Health care service providers should emphasize the actual experience of consultation. PMID- 27703338 TI - Development and application of culturally appropriate decision aids for smoking cessation in Korea: a pragmatic clustered randomization crossover trial. AB - INTRODUCTION: In Asian countries, reluctance to seek pharmacological intervention is a major barrier for smoking cessation. Culturally appropriate decision aids are expected to help people in the decision making for the use of smoking cessation medication. OBJECTIVE: The aim of this study was to develop a culturally tailored decision aid for smoking cessation and evaluate its effect on the use of smoking cessation medication. PATIENTS AND METHODS: A 7-minute video on smoking cessation information and options was developed. Physicians were randomized into intervention and control groups. The decision aid was provided to patients in the intervention group, and they watched it, while those in the control group were provided usual medical care for smoking cessation. The primary outcome was the proportion of smokers who were prescribed smoking cessation medication within 1 month after consultation. The secondary outcomes were abstinence rate and use of smoking cessation medication within 6 months. A logistic regression analysis was used to assess the effect of the decision aid on the outcomes. RESULTS: In total, 414 current smokers (intervention group: 195; control group: 219) were enrolled. The mean age of the participants was 48.2 years, and 381 subjects (92%) were males. In total, 11.8% of the participants in the intervention group and 10.5% in the control group were prescribed smoking cessation medications within 1 month. The odds ratio was 1.02 (95% CI: 0.40-2.63) after adjustment for baseline characteristics. Within 6 months, 17.4% of the participants in the intervention group and 15% in the control group were prescribed medication (adjusted odds ratio 1.12, 95% CI: 0.59-2.13). CONCLUSION: The culturally tailored smoking cessation decision aid developed in this study did not show a significant impact on the decision to use smoking cessation medication. Further research to develop more effective and more interactive interventions is expected. PMID- 27703339 TI - Characteristics of and outcomes for elderly patients with acute myocardial infarction: differences between females and males. AB - OBJECTIVES: This study analyzed age-adjusted sex differences among acute myocardial infarction (AMI) patients aged 75 years and above with regard to 7 year mortality (primary end point) and the frequency of angiograms and admission to the coronary care unit (CCU) as well as 1-year mortality (secondary end points). METHODS: A retrospective cohort study comprised 1,414 AMI patients (748 females and 666 males) aged at least 75 years, who were admitted to Sahlgrenska University Hospital in Gothenburg, Sweden, during two periods (2001/2002 and 2007). All comparisons between female and male patients were age adjusted. RESULTS: Females were older and their previous history included fewer AMIs, coronary artery bypass grafting procedures, and renal diseases, but more frequent incidence of hypertension. On the contrary, males had higher age-adjusted 7-year mortality in relation to females (hazard ratio [HR] 1.16 with corresponding 95% confidence interval [95% CI 1.03, 1.31], P=0.02). Admission to the CCU was more frequent among males than females (odds ratio [OR] 1.38 [95% CI 1.11, 1.72], P=0.004). There was a nonsignificant trend toward more coronary angiographies performed among males (OR 1.34 [95% CI 1.00, 1.79], P=0.05), as well as a nonsignificant trend toward higher 1-year mortality (HR 1.18 [95% CI 0.99, 1.39], P=0.06). CONCLUSION: In an AMI population aged 75 years and above, males had higher age-adjusted 7-year mortality and higher rate of admission to the CCU than females. One-year mortality did not differ significantly between the sexes, nor did the frequency of performed coronary angiograms. PMID- 27703341 TI - Cost-effectiveness and budget impact of the fixed-dose dual bronchodilator combination tiotropium-olodaterol for patients with COPD in the Netherlands. AB - PURPOSE: The fixed-dose dual bronchodilator combination (FDC) of tiotropium and olodaterol showed increased effectiveness regarding lung function and health related quality of life in patients with chronic obstructive pulmonary disease (COPD) compared with the use of its mono-components. Yet, while effectiveness and safety have been shown, the health economic implication of this treatment is still unknown. The aim of this study was to assess the cost-utility and budget impact of tiotropium-olodaterol FDC in patients with moderate to very severe COPD in the Netherlands. PATIENTS AND METHODS: A cost-utility study was performed, using an individual-level Markov model. To populate the model, individual patient level data (age, height, sex, COPD duration, baseline forced expiratory volume in 1 second) were obtained from the tiotropium-olodaterol TOnado trial. In the model, forced expiratory volume in 1 second and patient-level data were extrapolated to utility and survival, and treatment with tiotropium-olodaterol FDC was compared with tiotropium. Cost-utility analysis was performed from the Dutch health care payer's perspective using a 15-year time horizon in the base case analysis. The standard Dutch discount rates were applied (costs: 4.0%; effects: 1.5%). Both univariate and probabilistic sensitivity analyses were performed. Budget impact was annually assessed over a 5-year time horizon, taking into account different levels of medication adherence. RESULTS: As a result of cost increases, combined with quality-adjusted life-year (QALY) gains, results showed that tiotropium-olodaterol FDC had an incremental cost-effectiveness ratio of ?7,004/QALY. Without discounting, the incremental cost-effectiveness ratio was ?5,981/QALY. Results were robust in univariate and probabilistic sensitivity analyses. Budget impact was estimated at ?4.3 million over 5 years assuming 100% medication adherence. Scenarios with 40%, 60%, and 80% adherence resulted in lower 5-year incremental cost increases of ?1.7, ?2.6, and ?3.4 million, respectively. CONCLUSION: Tiotropium-olodaterol FDC can be considered a cost effective treatment under current Dutch cost-effectiveness thresholds. PMID- 27703340 TI - A concise review of testosterone and bone health. AB - Osteoporosis is a condition causing significant morbidity and mortality in the elderly population worldwide. Age-related testosterone deficiency is the most important factor of bone loss in elderly men. Androgen can influence bone health by binding to androgen receptors directly or to estrogen receptors (ERs) indirectly via aromatization to estrogen. This review summarized the direct and indirect effects of androgens on bone derived from in vitro, in vivo, and human studies. Cellular studies showed that androgen stimulated the proliferation of preosteoblasts and differentiation of osteoblasts. The converted estrogen suppressed osteoclast formation and resorption activity by blocking the receptor activator of nuclear factor k-B ligand pathway. In animal studies, activation of androgen and ERalpha, but not ERbeta, was shown to be important in acquisition and maintenance of bone mass. Human epidemiological studies demonstrated a significant relationship between estrogen and testosterone in bone mineral density and fracture risk, but the relative significance between the two remained debatable. Human experimental studies showed that estrogen was needed in suppressing bone resorption, but both androgen and estrogen were indispensable for bone formation. As a conclusion, maintaining optimal level of androgen is essential in preventing osteoporosis and its complications in elderly men. PMID- 27703342 TI - Chronic Pseudomonas aeruginosa infection-induced chronic bronchitis and emphysematous changes in CCSP-deficient mice. AB - The club cell secretory protein (CCSP) is a regulator of lung inflammation following acute respiratory infection or lung injury. Recently, the relationship between CCSP and COPD has been reported. Since COPD results from an abnormal inflammatory response, we hypothesized that CCSP could have a protective role against chronic inflammation-induced lung damage. To address this issue, the pathophysiology of chronic lung inflammation induced by Pseudomonas aeruginosa in CCSP-deficient mice was determined. A tube of 5 mm in length was soaked in a fluid containing P. aeruginosa (PAO01 strain) for 1 week and inserted into the trachea of CCSP-deficient mice. One week later, P. aeruginosa was administered into the trachea. Five weeks after insertion of tube, the mice were sacrificed. Bronchoalveolar lavage fluids were collected to determine the bacterial growth, and the lung histology and physiology were also examined. P. aeruginosa was continuously detected in bronchoalveolar lavage fluids during the study. Neutrophils were increased in the bronchoalveolar lavage fluids from the CCSP deficient mice in comparison to wild-type mice. A histological study demonstrated chronic inflammation around bronchus, serious bronchial stenosis, and alveolar enlargement in the CCSP-deficient mice. The lung physiology study demonstrated an increase in the lung compliance of the CCSP-deficient mice. Chronic P. aeruginosa inflammation resulted in chronic bronchitis and emphysematous changes in the CCSP deficient mice. CCSP could play an important role in protecting the host from the chronic inflammation-induced lung damage. PMID- 27703343 TI - Mortality associated with bone fractures in COPD patients. AB - BACKGROUND AND OBJECTIVE: COPD is well known to frequently coexist with osteoporosis. Bone fractures often occur and may affect mortality in COPD patients. However, in-hospital mortality related to bone fractures in COPD patients has been poorly studied. This retrospective study investigated in hospital mortality of COPD patients with bone fractures using a national inpatient database in Japan. METHODS: Data of COPD patients admitted with bone fractures, including hip, vertebra, shoulder, and forearm fractures to 1,165 hospitals in Japan between July 2010 and March 2013, were extracted from the Diagnosis Procedure Combination database. The clinical characteristics and mortalities of the patients were determined. Multivariable logistic regression analysis was also performed to determine the factors associated with in-hospital mortality of COPD patients with hip fractures. RESULTS: Among 5,975 eligible patients, those with hip fractures (n=4,059) were older, had lower body mass index (BMI), and had poorer general condition than those with vertebral (n=1,477), shoulder (n=281), or forearm (n=158) fractures. In-hospital mortality was 7.4%, 5.2%, 3.9%, and 1.3%, respectively. Among the hip fracture group, surgical treatment was significantly associated with lower mortality (adjusted odds ratio, 0.43; 95% confidence interval, 0.32-0.56) after adjustment for patient backgrounds. Higher in-hospital mortality was associated with male sex, lower BMI, lower level of consciousness, and having several comorbidities, including pneumonia, lung cancer, congestive heart failure, chronic liver disease, and chronic renal failure. CONCLUSION: COPD patients with hip fractures had higher mortality than COPD patients with other types of fracture. Surgery for hip fracture was associated with lower mortality than conservative treatment. PMID- 27703344 TI - Effectiveness using higher inhaled corticosteroid dosage in patients with COPD by different blood eosinophilic counts. AB - BACKGROUND: Blood eosinophil counts have been documented as a good biomarker for patients with chronic obstructive pulmonary disease (COPD) using inhaled corticosteroid (ICS) therapy. However, the effectiveness and safety of prescribing high or medium dose of ICS for patients with different eosinophil counts are unknown. METHODS: A post hoc analysis of a previous prospective randomized study was performed for COPD patients using higher dose (HD: Fluticasone 1,000 MUg/day) or medium dose (MD: Fluticasone 500 MUg/day) of ICS combined with Salmeterol (100 MUg/day). Patients were classified into two groups: those with high eosinophil counts (HE >=3%) and those with low eosinophil counts (LE <3%). Lung function was evaluated with forced expiratory volume in 1 second, forced vital capacity, and COPD assessment test. Frequencies of acute exacerbation and pneumonia were also measured. RESULTS: Two hundred and forty eight patients were studied and classified into higher eosinophil (HE) (n=85, 34.3%) and lower eosinophil (LE) groups (n=163, 65.7%). The levels of forced expiratory volume in 1 second were significantly increased in patients of HE group treated with HD therapy, compared with the other groups (HE/HD: 125.9+/ 27.2 mL vs HE/MD: 94.3+/-23.7 mL, vs LE/HD: 70.4+/-20.5 mL, vs LE/MD: 49.8+/-16.7 mL; P<0.05) at the end of the study. Quality of life (COPD assessment test) markedly improved in HE/HD group than in MD/LE group (HE/HD: 9+/-5 vs LE/MD: 16+/ 7, P=0.02). The frequency of acute exacerbation was more decreased in HE/HD group patients, compared with that in LE/MD group (HE/HD: 13.5% vs LE/MD: 28.7%, P<0.01). Pneumonia incidence was similar in the treatment groups (HE/HD: 3.2%, HE/MD: 2.6%, LE/HD: 3.5%, LE/MD 2.8%; P=0.38). CONCLUSION: The study results support using blood eosinophil counts as a biomarker of ICS response and show the benefits of greater improvement of lung function, quality of life, and decreased exacerbation frequency in COPD patients with blood eosinophil counts higher than 3%, especially treated with higher dose of ICS. PMID- 27703345 TI - Impaired training-induced adaptation of blood pressure in COPD patients: implication of the muscle capillary bed. AB - BACKGROUND AND AIMS: Targeting the early mechanisms in exercise-induced arterial hypertension (which precedes resting arterial hypertension in its natural history) may improve cardiovascular morbidity and mortality in COPD patients. Capillary rarefaction, an early event in COPD before vascular remodeling, is a potential mechanism of exercise-induced and resting arterial hypertension. Impaired training-induced capillarization was observed earlier in COPD patients; thus, this study compares the changes in blood pressure (BP) during exercise in COPD patients and matches control subjects (CSs) after a similar exercise training program, in relationship with muscle capillarization. METHODS: Resting and maximal exercise diastolic pressure (DP) and systolic pressure (SP) were recorded during a standardized cardiopulmonary exercise test, and a quadriceps muscle biopsy was performed before and after training. RESULTS: A total of 35 CSs and 49 COPD patients (forced expiratory volume in 1 second =54%+/-22% predicted) completed a 6-week rehabilitation program and improved their symptom-limited maximal oxygen uptake (VO2SL: 25.8+/-6.1 mL/kg per minute vs 27.9 mL/kg per minute and 17.0+/-4.7 mL/kg per minute vs 18.3 mL/kg per minute; both P<0.001). The improvement in muscle capillary-to-fiber (C/F) ratio was significantly greater in CSs vs COPD patients (+11%+/-9% vs +23%+/-21%; P<0.05). Although maximal exercise BP was reduced in CSs (DP: 89+/-10 mmHg vs 85+/-9 mmHg; P<0.001/SP: 204+/-25 mmHg vs 196+/-27 mmHg; P<0.05), it did not change in COPD patients (DP: 94+/-14 mmHg vs 97+/-16 mmHg; P=0.46/SP: 202+/-27 mmHg vs 208+/-24 mmHg; P=0.13). The change in muscle C/F ratio was negatively correlated with maximal exercise SP in CSs and COPD patients (r=-0.41; P=0.02). CONCLUSION: COPD patients showed impaired training-induced BP adaptation related to a change in muscle capillarization, suggesting the possibility of blunted angiogenesis. PMID- 27703346 TI - Inhaled corticosteroid normalizes some but not all airway vascular remodeling in COPD. AB - BACKGROUND: This study assessed the effects of inhaled corticosteroid (ICS) on airway vascular remodeling in chronic obstructive pulmonary disease (COPD). METHODS: Thirty-four subjects with mild-to-moderate COPD were randomly allocated 2:1 to ICS or placebo treatment in a double-blinded clinical trial over 6 months. Available tissue was compared before and after treatment for vessel density, and expression of VEGF, TGF-beta1, and TGF-beta1-related phosphorylated transcription factors p-SMAD 2/3. This clinical trial has been registered and allocated with the Australian New Zealand Clinical Trials Registry (ANZCTR) on 17/10/2012 with reference number ACTRN12612001111864. RESULTS: There were no significant baseline differences between treatment groups. With ICS, vessels and angiogenic factors did not change in hypervascular reticular basement membrane, but in the hypovascular lamina propria (LP), vessels increased and this had a proportionate effect on lung air trapping. There was modest evidence for a reduction in LP vessels staining for VEGF with ICS treatment, but a marked and significant reduction in p-SMAD 2/3 expression. CONCLUSION: Six-month high-dose ICS treatment had little effect on hypervascularity or angiogenic growth factors in the reticular basement membrane in COPD, but normalized hypovascularity in the LP, and this was physiologically relevant, though accompanied by a paradoxical reduction in growth factor expression. PMID- 27703347 TI - Microstructural, spectroscopic, and antibacterial properties of silver-based hybrid nanostructures biosynthesized using extracts of coriander leaves and seeds. AB - Coriander leaves and seeds have been highly appreciated since ancient times, not only due to their pleasant flavors but also due to their inhibitory activity on food degradation and their beneficial properties for health, both ascribed to their strong antioxidant activity. Recently, it has been shown that coriander leaf extracts can mediate the synthesis of metallic nanoparticles through oxidation/reduction reactions. In the present study, extracts of coriander leaves and seeds have been used as reaction media for the wet chemical synthesis of ultrafine silver nanoparticles and nanoparticle clusters, with urchin- and tree like shapes, coated by biomolecules (mainly, proteins and polyphenols). In this greener route of nanostructure preparation, the active biocompounds of coriander simultaneously play the roles of reducing and stabilizing agents. The morphological and microstructural studies of the resulting biosynthesized silver nanostructures revealed that the nanostructures prepared with a small concentration of the precursor Ag salt (AgNO3 =5 mM) exhibit an ultrafine size and a narrow size distribution, whereas particles synthesized with high concentrations of the precursor Ag salt (AgNO3 =0.5 M) are polydisperse and formation of supramolecular structures occurs. Fourier transform infrared and Raman spectroscopy studies indicated that the bioreduction of the Ag- ions takes place through their interactions with free amines, carboxylate ions, and hydroxyl groups. As a consequence of such interactions, residues of proteins and polyphenols cap the biosynthesized Ag nanoparticles providing them a hybrid core/shell structure. In addition, these biosynthesized Ag nanomaterials exhibited size-dependent plasmon extinction bands and enhanced bactericidal activities against both Gram-positive and Gram-negative bacteria, displaying minimal inhibitory Ag concentrations lower than typical values reported in the literature for Ag nanoparticles, probably due to the synergy of the bactericidal activities of the Ag nanoparticle cores and their capping ligands. PMID- 27703348 TI - Stealth, biocompatible monoolein-based lyotropic liquid crystalline nanoparticles for enhanced aloe-emodin delivery to breast cancer cells: in vitro and in vivo studies. AB - Recently, research has progressively highlighted on clues from conventional use of herbal medicines to introduce new anticancer drugs. Aloe-emodin (AE) is a herbal drug with promising anticancer activity. Nevertheless, its clinical utility is handicapped by its low solubility. For the first time, this study aims to the fabrication of surface-functionalized polyethylene glycol liquid crystalline nanoparticles (PEG-LCNPs) of AE to enhance its water solubility and enable its anticancer use. Developed AE-PEG-LCNPs were optimized via particle size and zeta potential measurements. Phase behavior, solid state characteristics, hemocompatibility, and serum stability of LCNPs were assessed. Sterile formulations were developed using various sterilization technologies. Furthermore, the potential of the formulations was investigated using cell culture, pharmacokinetics, biodistribution, and toxicity studies. AE-PEG-LCNPs showed particle size of 190 nm and zeta potential of -49.9, and PEGylation approach reduced the monoolein hemolytic tendency to 3% and increased the serum stability of the nanoparticles. Sterilization of liquid and lyophilized AE-PEG LCNPs via autoclaving and gamma-radiations, respectively, insignificantly affected the physicochemical properties of the nanoparticles. Half maximal inhibitory concentration of AE-PEG-LCNPs was 3.6-fold lower than free AE after 48 hours and their cellular uptake was threefold higher than free AE after 24-hour incubation. AE-PEG-LCNPs presented 5.4-fold increase in t1/2 compared with free AE. Biodistribution and toxicity studies showed reduced AE-PEG-LCNP uptake by reticuloendothelial system organs and good safety profile. PEGylated LCNPs could serve as a promising nanocarrier for efficient delivery of AE to cancerous cells. PMID- 27703350 TI - Viruses as nanomedicine for cancer. AB - Oncolytic virotherapy, a type of nanomedicine in which oncolytic viruses (OVs) are used to selectively infect and lyse cancer cells, is an emerging field in cancer therapy. Some OVs exhibit a specific tropism for cancer cells, whereas others require genetic modification to enhance their binding with and entry into cancer cells. OVs both kill tumor cells and induce the host's immune response against tumor cells. Armed with antitumor cellular molecules, antibodies, and/or in combination with anticancer drugs, OVs can accelerate the lysis of cancer cells. Among the OVs, vaccinia virus has been the focus of preclinical and clinical research because of its many favorable properties. In this review, the basic mechanisms of action of OVs are presented, including their entry, survival, tumor lysis, and immune activation, and the latest research in vaccinia virus based virotherapy and its status as an anticancer nanomedicine in prospective clinical trials are discussed. PMID- 27703349 TI - TiO2 nanotube platforms for smart drug delivery: a review. AB - Titania nanotube (TNT) arrays are recognized as promising materials for localized drug delivery implants because of their excellent properties and facile preparation process. This review highlights the concept of localized drug delivery systems based on TNTs, considering their outstanding biocompatibility in a series of ex vivo and in vivo studies. Considering the safety of TNT implants in the host body, studies of the biocompatibility present significant importance for the clinical application of TNT implants. Toward smart TNT platforms for sustainable drug delivery, several advanced approaches were presented in this review, including controlled release triggered by temperature, light, radiofrequency magnetism, and ultrasonic stimulation. Moreover, TNT implants used in medical therapy have been demonstrated by various examples including dentistry, orthopedic implants, cardiovascular stents, and so on. Finally, a future perspective of TNTs for clinical applications is provided. PMID- 27703351 TI - Treatment of natural mammary gland tumors in canines and felines using gold nanorods-assisted plasmonic photothermal therapy to induce tumor apoptosis. AB - Plasmonic photothermal therapy (PPTT) is a cancer therapy in which gold nanorods are injected at the site of a tumor before near-infrared light is transiently applied to the tumor causing localized cell death. Previously, PPTT studies have been carried out on xenograft mice models. Herein, we report a study showing the feasibility of PPTT as applied to natural tumors in the mammary glands of dogs and cats, which more realistically represent their human equivalents at the molecular level. We optimized a regime of three low PPTT doses at 2-week intervals that ablated tumors mainly via apoptosis in 13 natural mammary gland tumors from seven animals. Histopathology, X-ray, blood profiles, and comprehensive examinations were used for both the diagnosis and the evaluation of tumor statuses before and after treatment. Histopathology results showed an obvious reduction in the cancer grade shortly after the first treatment and a complete regression after the third treatment. Blood tests showed no obvious change in liver and kidney functions. Similarly, X-ray diffraction showed no metastasis after 1 year of treatment. In conclusion, our study suggests the feasibility of applying the gold nanorods-PPTT on natural tumors in dogs and cats without any relapse or toxicity effects after 1 year of treatment. PMID- 27703353 TI - Splitting, impulsivity, and intimate partnerships in young obese women seeking bariatric treatment. AB - BACKGROUND: Splitting represents a defense mechanism that describes fragmentation of conscious experience that may occur in various psychopathological conditions. The purpose of this study was to examine the relationship of splitting with disturbed cognitive and affective functions related to impulsivity and intimate partnerships in a group of obese patients indicated for bariatric treatment and compare the results with other obese patients and patients with bulimia nervosa. METHODS: In this clinical study, we assessed 102 young women. The sample was divided into three subgroups: obese women (N=30), obese women indicated for bariatric treatment (N=48), and patients with bulimia nervosa (N=24). The patients were assessed using Splitting Index and Barratt Impulsivity Scale, and selected information about their intimate partnership was documented for all the participants. RESULTS: The main results of this study indicate significant differences in the relationship of splitting and impulsivity with difficulties in intimate partnerships. These differences discriminate obese patients indicated for bariatric treatment from other obese patients and patients with bulimia nervosa. CONCLUSION: These findings may have significant implications for treatment of the obese patients indicated for bariatric treatment and their presurgery psychological evaluations. PMID- 27703352 TI - Multimodal near-infrared-emitting PluS Silica nanoparticles with fluorescent, photoacoustic, and photothermal capabilities. AB - PURPOSE: The aim of the present study was to develop nanoprobes with theranostic features, including - at the same time - photoacoustic, near-infrared (NIR) optical imaging, and photothermal properties, in a versatile and stable core shell silica-polyethylene glycol (PEG) nanoparticle architecture. MATERIALS AND METHODS: We synthesized core-shell silica-PEG nanoparticles by a one-pot direct micelles approach. Fluorescence emission and photoacoustic and photothermal properties were obtained at the same time by appropriate doping with triethoxysilane-derivatized cyanine 5.5 (Cy5.5) and cyanine 7 (Cy7) dyes. The performances of these nanoprobes were measured in vitro, using nanoparticle suspensions in phosphate-buffered saline and blood, dedicated phantoms, and after incubation with MDA-MB-231 cells. RESULTS: We obtained core-shell silica-PEG nanoparticles endowed with very high colloidal stability in water and in biological environment, with absorption and fluorescence emission in the NIR field. The presence of Cy5.5 and Cy7 dyes made it possible to reach a more reproducible and higher doping regime, producing fluorescence emission at a single excitation wavelength in two different channels, owing to the energy transfer processes within the nanoparticle. The nanoarchitecture and the presence of both Cy5.5 and Cy7 dyes provided a favorable agreement between fluorescence emission and quenching, to achieve optical imaging and photoacoustic and photothermal properties. CONCLUSION: We obtained rationally designed nanoparticles with outstanding stability in biological environment. At appropriate doping regimes, the presence of Cy5.5 and Cy7 dyes allowed us to tune fluorescence emission in the NIR for optical imaging and to exploit quenching processes for photoacoustic and photothermal capabilities. These nanostructures are promising in vivo theranostic tools for the near future. PMID- 27703354 TI - The role of augmentative and alternative communication for children with autism: current status and future trends. AB - BACKGROUND: Augmentative and alternative communication (AAC) interventions are used for children with autism, often as stand-alone communication interventions for those who are minimally verbal. Our aim was to synthesize the evidence for AAC interventions for children (up to 21 years), and then consider the role of AAC within established, comprehensive, evidence-based autism interventions targeting learning across multiple developmental domains. DESIGN: We completed a systematic search of three databases (OVID Medline, PsycINFO, ERIC) as well as forward citation and hand searches to identify systematic reviews of AAC intervention efficacy research including children with autism, published between 2000 and March 2016 in peer-reviewed journals. Data pertaining to the quality indicators of included studies, effect sizes for intervention outcomes, and evidence for effectiveness were extracted for descriptive analysis. RESULTS: The search yielded 17 systematic reviews. Most provided indicators of research quality for included studies, of which only relatively few provided conclusive results. Communication targets tended to be focused on teaching children to make requests. Still, effect size measures for included studies indicated that AAC was effective to highly effective. CONCLUSION: There is growing evidence for the potential benefits of AAC for children with autism, but there is a need for more well-designed studies and broader, targeted outcomes. Furthermore, a lack of evidence for the role of AAC within comprehensive intervention programs may account for a tendency by autism researchers and practitioners to neglect this intervention. Attempts to compare evidence for AAC with other interventions for children with autism, including those in which the use of AAC is delayed or excluded in pursuit of speech-only communication, must take into account the needs of children with the most significant learning needs. These children pose the greatest challenges to achieving large and consistent intervention effects, yet stand to gain the most from AAC interventions. PMID- 27703355 TI - Noradrenaline plays a critical role in the switch to a manic episode and treatment of a depressive episode. AB - Although antidepressants may increase the risk of switching to mania in bipolar disorder (BD), clinicians have been using antidepressants to treat patients with bipolar depression. Appropriate treatments for bipolar depression remain controversial. In BD, antidepressants comprise a double-edged sword in terms of their efficacy in treating depression and the increased risk of switching. This review presents an important table outlining the benefit in terms of depression improvement and the risk of switching in the clinical setting. It also proposes strategies based on the characteristics of antidepressants such as their pharmacology, specifically the equilibrium dissociation constant (KD) of the noradrenaline transporter. This table will be useful for clinicians while considering benefit and risk. Antidepressants augmenting noradrenaline may be effective in bipolar depression. However, it is easily presumed that such antidepressants may also have a risk of switching to mania. Therefore, antidepressants augmenting noradrenaline will be the recommended treatment in combination with an antimanic agent, or they may be used for short-term treatment and early discontinuation. The corresponding medical treatment guidelines probably need to be reevaluated and updated based on biological backgrounds. From previous studies, we understand that the stability of noradrenaline levels is important for BD amelioration, based on the pathophysiology of the disorder. It is hoped that researchers will reevaluate BD by conducting studies involving noradrenaline.

AB - OBJECTIVE: The differential diagnosis of schizophrenia (SZ) versus autism spectrum disorder (ASD) can be clinically challenging because accumulating evidence suggests both clinical and biological overlaps between them. The aim of this study was to compare Rorschach profiles between young adults with SZ and those with ASD. METHODS: We evaluated quantitative tendencies on the Rorschach test among 20 patients diagnosed with SZ and 20 diagnosed with ASD. Both groups were matched for age, sex, and intelligence quotient. RESULTS: We found significant differences in six response variables on the Rorschach comprehensive system. Those with SZ had significantly higher scores on D score, adjusted D score (Adj D), developmental quality code reflecting ordinary response (DQo), and form quality minus (FQ -) than those with ASD. In contrast, those with SZ had significantly lower scores on the active and developmental quality code reflecting synthesized response (DQ+) subscales than those with ASD. CONCLUSION: The present findings reveal that individuals with SZ might have more stress tolerance, stronger perception distortions, and simpler and poorer recognition than those with ASD. We suggest that the Rorschach test might be a useful tool for differentiating between SZ and ASD. PMID- 27703358 TI - miR-370 mimic inhibits replication of Japanese encephalitis virus in glioblastoma cells. AB - Japanese encephalitis (JE) is one of the most severe viral infections of the central nervous system. No effective treatment for JE currently exists, because its pathogenesis remains largely unknown. The present study was designed to screen the potential microRNAs (miRNAs) involved in JE. Glioblastoma cells were collected, after being infected with the Japanese encephalitis virus (JEV). Total miRNAs were extracted and analyzed using an miRNA chip. One of the most severely affected miRNAs was selected, and the role of miR-370 in JEV infection was investigated. Cell viability and apoptosis of the host cells were evaluated. JEV replication was detected via analysis of gene E expression. Real-time polymerase chain reaction was used to determine the levels of endogenous miR-370 and expression of innate immunity-related genes. Following JEV infection, 114 miRNAs were affected, as evidenced by the miRNA chip. Among them, 30 miRNAs were upregulated and 84 were downregulated. The changes observed in five miRNAs were confirmed by real-time polymerase chain reaction. One of the significantly downregulated miRNAs was miR-370. Therefore, miR-370 mimic was transfected into the cells, following which the levels of endogenous miR-370 were significantly elevated. Concurrently, JEV replication was significantly reduced 24 hours after transfection of miR-370 mimic. Functionally, miR-370 mimic mitigated both JEV induced apoptosis and the inhibition of host cell proliferation. Following JEV infection, interferon-beta and nuclear factor-kappa B were upregulated, whereas miR-370 mimic prevented the upregulation of the genes induced by JEV infection. The present study demonstrated that miR-370 expression in host cells is downregulated following JEV infection, which further mediates innate immunity related gene expression. Taken together, miR-370 mimic might be useful to prevent viral replication and infection-induced host cell injury. PMID- 27703356 TI - Nine traditional Chinese herbal formulas for the treatment of depression: an ethnopharmacology, phytochemistry, and pharmacology review. AB - Depression is a major mental disorder, and is currently recognized as the second leading cause of disability worldwide. However, the therapeutic effect of antidepressants remains unsatisfactory. For centuries, Chinese herbal formulas (CHFs) have been widely used in the treatment of depression, achieving better therapeutic effects than placebo and having fewer side effects than conventional antidepressants. Here, we review the ethnopharmacology, phytochemistry, and pharmacology studies of nine common CHFs: "banxia houpo" decoction, "chaihu shugansan", "ganmaidazao" decoction, "kaixinsan", "shuganjieyu" capsules, "sinisan", "wuling" capsules, "xiaoyaosan", and "yueju". Eight clinical trials and seven meta-analyses have supported the theory that CHFs are effective treatments for depression, decreasing Hamilton Depression Scale scores and showing few adverse effects. Evidence from 75 preclinical studies has also elucidated the multitarget and multipathway mechanisms underlying the antidepressant effect of the nine CHFs. Decoctions, capsules, and pills all showed antidepressant effects, ranked in descending order of efficacy. According to traditional Chinese medicine theory, these CHFs have flexible compatibility and mainly act by soothing the liver and relieving depression. This review highlights the effective treatment choices and candidate compounds for patients, practitioners, and researchers in the field of traditional Chinese medicine. In summary, the current evidence supports the efficacy of CHFs in the treatment of depression, but additional large-scale randomized controlled clinical trials and sophisticated pharmacology studies should be performed. PMID- 27703359 TI - Increased frontal electroencephalogram theta amplitude in patients with anorexia nervosa compared to healthy controls. AB - OBJECTIVE: To conduct a blind study of quantitative electroencephalogram-band amplitudes in patients with anorexia nervosa (AN) and healthy controls. METHODS: Twenty-one patients with AN and 24 controls were examined with eyes-closed 16 channel electroencephalogram. Main variables were absolute alpha, theta, and delta amplitudes in frontal, temporal, and posterior regions. RESULTS: There were no significant differences between the AN patients and controls regarding absolute regional band amplitudes in MUV. Borderline significance was found for anterior theta (P=0.051). Significantly increased left and right frontal electrode theta amplitude was found in AN patients (F3, P=0.014; F4, P=0.038) compared to controls. Significant differences were also observed for secondary variables: lower values for relative parietooccipital delta and frontocentral alpha activity among AN patients than among controls. CONCLUSION: We observed slight excess frontal theta and lower relative alpha and delta amplitudes among AN patients than among controls. This pattern is possibly related to a slight frontal lobe dysfunction in AN, or it may reflect increased attention/vigilance or another state-related change in patients with AN compared to healthy controls. PMID- 27703361 TI - Mean platelet volume and red cell distribution width levels in initial evaluation of panic disorder. AB - BACKGROUND: As the relationship between psychological stress and platelet activation has been widely studied in recent years, activated platelets lead to certain biochemical changes, which occur in the brain in patients with mental disorders. However, data relating to the mean platelet volume (MPV) in patients with panic disorder (PD) are both limited and controversial. Herein, we aimed to evaluate, for the first time, the red cell distribution width (RDW) levels combined with MPV levels in patients with PD. PATIENTS AND METHODS: Between January 2012 and June 2015, data of 30 treatment-naive patients (16 females, 14 males; mean age: 37+/-10 years; range: 18-59 years) who were diagnosed with PD and 25 age- and sex-matched healthy volunteers (10 females, 15 males; mean age: 36+/-13 years; range: 18-59 years) (control group) were retrospectively analyzed. The white blood cell count (WBC), MPV, and RDW levels were measured in both groups. RESULTS: The mean WBC, MPV, and RDW levels were 9,173.03+/-2,400.31/mm3, 8.19+/-1.13 fl, and 12.47+/-1.14%, respectively, in the PD group. These values were found to be 7,090.24+/-1,032.61, 6.85+/-0.67, and 11.63+/-0.85, respectively, in the healthy controls. The WBC, MPV, and RDW levels were significantly higher in the patients with PD compared to the healthy controls (P=0.001, P=0.001, and P=0.003, respectively). However, there was no significant difference in the platelet number between the patients with PD and healthy controls (P>0.05). CONCLUSION: Our study results are the first to demonstrate that the RDW levels combined with MPV levels significantly increase among patients with PD. We believe that increased RDW and MPV levels can be used as a novel marker for PD. PMID- 27703360 TI - Delirium as a complication of the surgical intensive care. AB - BACKGROUND: The aim of this study was to examine the impact of somatic illnesses, electrolyte imbalance, red blood cell count, hypotension, and antipsychotic and opioid treatment on the duration of delirium in Central Intensive Care Unit for Surgery. PATIENTS AND METHODS: Patients who were admitted to the Department of Central Intensive Care Unit for Surgery in the University Hospital Olomouc from February 2004 to November 2008 were evaluated using Riker sedation-agitation scale. Their blood pressure, heart rate, respiratory rate, and peripheral blood oxygen saturation were measured continually, and body temperature was monitored once in an hour. The laboratory blood tests including sodium, potassium, chlorides, phosphorus, urea and creatinine, hemoglobin, hematocrit, red and white blood cell count, and C-reactive protein, albumin levels and laboratory markers of renal and liver dysfunction were done every day. All measurements were made at least for ten consecutive days or longer until the delirium resolved. RESULTS: The sample consisted of 140 consecutive delirious patients with a mean age of 68.21+/-12.07 years. Delirium was diagnosed in 140 of 5,642 patients (2.48%) admitted in CICUS in the last 5 years. The median duration of delirium was 48 hours with a range of 12-240 hours. Statistical analysis showed that hyperactive subtype of delirium and treatment with antipsychotics were associated with prolonged delirium duration (hyperactive 76.15+/-40.53 hours, hypoactive 54.46+/ 28.44 hours, mixed 61.22+/-37.86 hours; Kruskal-Wallis test: 8.022; P<0.05). The duration of delirium was significantly correlated also with blood potassium levels (Pearson's r=0.2189, P<0.05), hypotension (hypotension 40.41+/-30.23 hours versus normotension 70.47+/-54.98 hours; Mann-Whitney U=1,512; P<0.05), administration of antipsychotics compared to other drugs (antipsychotics 72.83+/ 40.6, benzodiazepines 42.00+/-20.78, others drugs, mostly piracetam 46.96+/-18.42 hours; Kruskal-Wallis test: 17.39, P<0.0005), and history of alcohol abuse (with a history of abuse 73.63+/-45.20 hours, without a history of abuse 59.54+/-30.61 hours; Mann-Whitney U=1,840; P<0.05). One patient had suffered from complicated postoperative hypostatic pneumonia and died due to respiratory failure (patient with hypoactive subtype). According to the backward stepwise multiple regression, the best significant predictors of duration of the delirium were the hypotension, type of psychopharmacs, type of delirium, the daily dose of opioids, a combination of psychopharmacs, history of alcohol abuse, plasma level of potassium, anemia, hyperpyrexia, and plasma level of albumin, reaching statistical significance (analysis of variance: F=5.205; df=24; P<0.005; adjusted r2=0.637). CONCLUSION: The hyperactive type of delirium, hypotension, usage of antipsychotics, the higher daily dose of opioids, a combination of psychopharmacs, history of alcohol abuse, low blood levels of potassium, anemia, hyperpyrexia, and hypoalbuminemia in the CICUS were associated with longer duration of delirium. PMID- 27703363 TI - Development of psychotic symptoms following ingestion of small quantities of alcohol. AB - Psychotic symptoms can occur in some clinical conditions related to alcohol, such as intoxication, withdrawal, and other alcohol-induced neuropsychiatric disorders. Here, we present a case report of a 24-year-old man, without a known psychiatric history, who developed brief psychotic symptoms following ingestion of small quantities of alcohol repeatedly. To our knowledge, no related previous literature regarding this has been reported. PMID- 27703362 TI - Self-stigma in borderline personality disorder - cross-sectional comparison with schizophrenia spectrum disorder, major depressive disorder, and anxiety disorders. AB - INTRODUCTION: Self-stigma arises from one's acceptance of societal prejudices and is common in psychiatric patients. This investigation compares the self-stigma of a sample of patients with borderline personality disorder (BPD), schizophrenia spectrum disorder (SCH), major depressive disorder (MDD), bipolar affective disorder (BAD), and anxiety disorders (AD) and explores of the self-stigma with the subjective and objective measures of the severity of the disorder and demographic factors. METHODS: The total of 184 inpatients admitted to the psychotherapeutic department diagnosed with BPD, SCH, MDD, BAP, and AD were compared on the internalized stigma of mental illness (ISMI) scale. The ISMI total score was correlated with the subjective and objective evaluation of the disorder severity (clinical global impression), and clinical and demographic factors. RESULTS: The self-stigma levels were statistically significantly different among the diagnostic groups (BPD 71.15+/-14.74; SCH 63.2+/-13.27; MDD 64.09+/-12.2; BAD 62.0+/-14.21; AD 57.62+/-15.85; one-way analysis of variance: F=8.698, df=183; P<0.005). However after applying the Bonferroni's multiple comparison test, the only significant difference was between the BPD patients and the patients with AD (P<0.001). Stepwise regression analysis showed that the strongest factors connected with the higher level of self-stigma were being without partner, the number of hospitalization, and the severity of the disorder. CONCLUSION: The BPD patients suffer from a higher level of self-stigma compared to patients with AD. In practice, it is necessary to address the reduction of self-stigma by using specific treatment strategies, such as cognitive therapy. PMID- 27703364 TI - In vitro and in vivo postmarketing surveillance of valsartan, alone or in combination with amlodipine or hydrochlorothiazide, among Palestinian hypertensive patients. AB - OBJECTIVES: The objectives of this study were to evaluate the general quality of the most prescribed products of valsartan (VL; alone or in combination) and to evaluate their efficacy and safety among Palestinian population through in vivo postmarketing surveillance. PATIENTS AND METHODS: The first part was pharmacopeial quality control assay, including dissolution, disintegration, friability, and weight uniformity for VL. The second part was a 3-month cardiology clinics, observational, postmarketing surveillance pilot study that included 103 hypertensive patients who were prescribed 80 mg or 160 mg of VL as monotherapy or combination therapy. The end points were reduction in blood pressure (BP) and the rate of incidence of adverse effects (AEs) at weeks 4 and 8. RESULTS: According to our quality control tests, all VL products showed high quality standards according to the international guidelines. A reduction in BP was observed at weeks 4 and 8, and no significant difference was observed between the strengths of 80 mg and 160 mg. Higher BP reduction was observed after the use of combination therapy. Moreover, VL was well tolerated; most of the AEs were of mild-to-moderate intensity. In general, the most frequently reported AEs included headache (17.5%), dizziness (11.75%), and weakness (11.7%). No serious AEs or death cases were reported during the study period. CONCLUSION: High quality of VL tablet products was used; hence, the observed efficacy and safety results should be related to patient's factors and not due to any product defects or substandard quality. Moreover, VL is an effective treatment for essential hypertension. PMID- 27703365 TI - Long-term safety of tiotropium delivered by Respimat(r) SoftMistTM Inhaler: patient selection and special considerations. AB - Tiotropium bromide is a long-acting inhaled muscarinic antagonist used in patients with chronic respiratory disease. It has been available since 2002 as a single-dose dry powder formulation via the HandiHaler(r) dry powder inhaler (DPI) device, and since 2007 as the Respimat(r) SoftMistTM Inhaler (SMI). The latter is a novel method of medication delivery that utilizes a multidose aqueous solution to deliver the drug as a fine mist. Potential benefits include more efficient drug deposition throughout the respiratory tract, reduced systemic exposure, and greater ease of use and patient satisfaction compared with the use of HandiHaler DPI. Although tiotropium bromide delivered via the HandiHaler DPI has been clearly shown to improve lung function, dyspnea, and quality of life and to reduce exacerbations in patients with chronic obstructive pulmonary disease (COPD), there is accumulating evidence regarding the use of tiotropium HandiHaler in other respiratory diseases characterized by airflow limitation, such as asthma and cystic fibrosis. Developed more recently, tiotropium delivered via the Respimat SMI appears to have a similar efficacy and safety profile to the HandiHaler DPI, and early data raising the possibility of safety concerns with its use in COPD have been refuted by more recent evidence. The benefits over the HandiHaler DPI, however, remain unclear. This paper will review the evidence for tiotropium delivered via the Respimat SMI inhaler, in particular as an alternative to the HandiHaler DPI, and will focus on the safety profile for each of the chronic lung diseases in which it has been trialed, as well as an approach to appropriate patient selection. PMID- 27703366 TI - Clinical, pathological, and radiological characteristics of solitary ground-glass opacity lung nodules on high-resolution computed tomography. AB - BACKGROUND: Lung nodules are being detected at an increasing rate year by year with high-resolution computed tomography (HRCT) being widely used. Ground-glass opacity nodule is one of the special types of pulmonary nodules that is confirmed to be closely associated with early stage of lung cancer. Very little is known about solitary ground-glass opacity nodules (SGGNs). In this study, we analyzed the clinical, pathological, and radiological characteristics of SGGNs on HRCT. METHODS: A total of 95 resected SGGNs were evaluated with HRCT scan. The clinical, pathological, and radiological characteristics of these cases were analyzed. RESULTS: Eighty-one adenocarcinoma and 14 benign nodules were observed. The nodules included 12 (15%) adenocarcinoma in situ (AIS), 14 (17%) minimally invasive adenocarcinoma (MIA), and 55 (68%) invasive adenocarcinoma (IA). No patients with recurrence till date have been identified. The positive expression rates of anaplastic lymphoma kinase and ROS-1 (proto-oncogene tyrosine-protein kinase ROS) were only 2.5% and 8.6%, respectively. The specificity and accuracy of HRCT of invasive lung adenocarcinoma were 85.2% and 87.4%. The standard uptake values of only two patients determined by 18F-FDG positron emission tomography/computed tomography (PET/CT) were above 2.5. The size, density, shape, and pleural tag of nodules were significant factors that differentiated IA from AIS and MIA. Moreover, the size, shape, margin, pleural tag, vascular cluster, bubble-like sign, and air bronchogram of nodules were significant determinants for mixed ground-glass opacity nodules (all P<0.05). CONCLUSION: We analyzed the clinical, pathological, and radiological characteristics of SGGNs on HRCT and found that the size, density, shape, and pleural tag of SGGNs on HRCT are found to be the determinant factors of IA. In conclusion, detection of anaplastic lymphoma kinase expression and performance of PET/CT scan are not routinely recommended. PMID- 27703368 TI - Postherpetic neuralgia: epidemiology, pathophysiology, and pain management pharmacology. AB - Herpes zoster, also known as shingles, is a distinctive clinical condition caused by the reactivation of latent varicella zoster (chickenpox) virus following an initial infection. Approximately 1 million cases of herpes zoster occur annually in the US, and one in every three people develops herpes zoster during their lifetime. Postherpetic neuralgia is a neuropathic pain syndrome characterized by pain that persists for months to years after resolution of the herpes zoster rash. It stems from damage to peripheral and central neurons that may be a byproduct of the immune/inflammatory response accompanying varicella zoster virus reactivation. Patients with postherpetic neuralgia report decreased quality of life and interference with activities of daily living. Approaches to management of postherpetic neuralgia include preventing herpes zoster through vaccination and/or antiviral treatment, and administering specific medications to treat pain. Current guidelines recommend treatment of postherpetic neuralgia in a hierarchical manner, with calcium channel alpha2-delta ligands (gabapentin and pregabalin), tricyclic antidepressants (amitriptyline, nortriptyline, or desipramine), or topical lidocaine patches as first-line drugs. The safety and tolerability of pharmacologic therapies for pain are important issues to consider as postherpetic neuralgia affects primarily an older population. Patients should be educated on appropriate dosing, titration if applicable, the importance of adherence to treatment for optimal effectiveness, and possible side effects. Health-care professionals play a key role in helping to ameliorate the pain caused by postherpetic neuralgia through early recognition and diligent assessment of the problem; recommending evidence-based treatments; and monitoring treatment adherence, adverse events, responses, and expectations. Nurse practitioners are especially crucial in establishing communication with patients and encouraging the initiation of appropriate pain-relieving treatments. PMID- 27703367 TI - Efficacy and safety of daptomycin for skin and soft tissue infections: a systematic review with trial sequential analysis. AB - BACKGROUND: Skin and soft tissue infections (SSTIs) are significant indications for antibiotic treatment. Daptomycin, a novel antibiotic, has been registered and licensed to be used in the treatment of these infections. However, its efficacy and safety remain controversial. OBJECTIVE: The objective of this study was to conduct a systematic review with trial sequential analysis (TSA) to evaluate the efficacy and safety of daptomycin for the treatment of SSTIs and to analyze whether the available sample size has been large enough and is conclusive. METHODS: PubMed, the Cochrane Library, and EMBASE were searched for published randomized controlled trials (RCTs) that compared daptomycin with other antibiotics in adult patients with SSTIs up to February 2016. RESULTS: This meta analysis included eight randomized controlled trials (n=2,002). There was no difference in either the clinical success rate (intention-to-treat population: relative risk [RR] =1.04, 95% confidence interval [CI] =0.99-1.10, P=0.12; clinically evaluable population: RR =1.00, 95% CI =0.97-1.04, P=0.82) or the microbiological success rate (RR =1.00, 95% CI =0.95-1.06, P=0.92) between the daptomycin and comparator groups for treating SSTIs, which was confirmed by TSA. Compared with vancomycin, daptomycin exhibited no advantage in increasing the clinical success rate (RR =1.03, 95% CI =0.95-1.13, P=0.47), and this was also confirmed by TSA. All-cause mortality, overall treatment-related adverse events, and creatine phosphokinase events were similar between these two groups. CONCLUSION: Daptomycin and comparator drugs are equally efficacious with regard to clinical and microbiological success for patients with SSTIs, and TSA showed that no additional randomized controlled trials are required. Although daptomycin is a good alternative when other antibiotics are contraindicated for patients with SSTIs and it can serve as a first-line treatment for SSTIs, clinicians should be aware of potential adverse events, such as daptomycin-induced acute eosinophilic pneumonia and creatine phosphokinase, when treating patients with daptomycin.

AB - [This retracts the article on p. 1997 in vol. 9, PMID: 27103825.][This retracts the article on p. 841 in vol. 28.]. PMID- 27703369 TI - Multidisciplinary rehabilitation for patients with cerebral palsy: improving long term care. AB - Cerebral palsy (CP) is one of the most frequent causes of child disability in developed countries. Children with CP need lifelong assistance and care. The current prevalence of CP in industrialized countries ranges from 1.5 to 2.5 per 1,000 live births, with one new case every 500 live births. Children with CP have an almost normal life expectancy and mortality is very low. Despite the low mortality rate, 5%-10% of them die during childhood, especially when the severe motor disability is comorbid with epilepsy and severe intellectual disability. Given this life expectancy, children with CP present with a lifelong disability of varying severity and complexity, which requires individualized pathways of care. There are no specific treatments that can remediate the brain damage responsible for the complex clinical-functional dysfunctions typical of CP. There are, however, a number of interventions (eg, neurorehabilitation, functional orthopedic surgery, medication, etc) aimed at limiting the damage secondary to the brain insult and improving these patients' activity level and participation and, therefore, their quality of life. The extreme variability of clinical aspects and the complexity of affected functions determine a multifaceted skill development in children with CP. There is a need to provide them with long-term care, taking into account medical and social aspects as well as rehabilitation, education, and assistance. This long-term care must be suited according to children's developmental stage and their physical, psychological, and social development within their life contexts. This impacts heavily on the national health systems which must set up a network of services for children with CP, and it also impacts heavily on the family as a whole, due to the resulting distress, adjustment efforts, and changes in quality of life. This contribution is a narrative review of the current literature on long-term care for children with CP, aiming at suggesting reflections to improve these children's care. PMID- 27703371 TI - Identifying module biomarkers from gastric cancer by differential correlation network. AB - Gastric cancer (stomach cancer) is a severe disease caused by dysregulation of many functionally correlated genes or pathways instead of the mutation of individual genes. Systematic identification of gastric cancer biomarkers can provide insights into the mechanisms underlying this deadly disease and help in the development of new drugs. In this paper, we present a novel network-based approach to predict module biomarkers of gastric cancer that can effectively distinguish the disease from normal samples. Specifically, by assuming that gastric cancer has mainly resulted from dysfunction of biomolecular networks rather than individual genes in an organism, the genes in the module biomarkers are potentially related to gastric cancer. Finally, we identified a module biomarker with 27 genes, and by comparing the module biomarker with known gastric cancer biomarkers, we found that our module biomarker exhibited a greater ability to diagnose the samples with gastric cancer. PMID- 27703372 TI - Consolidation chemotherapy improves progression-free survival in stage III small cell lung cancer following concurrent chemoradiotherapy: a retrospective study. AB - BACKGROUND: Concurrent chemoradiotherapy (CCRT) is the standard treatment for limited-stage small-cell lung cancer (LD-SCLC). However, the efficacy of consolidation chemotherapy (CCT) in LD-SCLC remains controversial despite several studies that were performed in the early years of CCT use. The aim of this study was to reevaluate the effectiveness and toxicities associated with CCT. METHODS: This retrospective analysis evaluated 177 patients with stage IIIA and IIIB small cell lung cancer (SCLC) who underwent CCRT from January 2001 to December 2013 at Sun Yat-Sen University Cancer Center (SYSUCC). Overall survival (OS) and progression-free survival (PFS) were analyzed using Kaplan-Meier methods. Univariate and multivariate analyses were performed to analyze patient prognosis factors. RESULTS: Among the 177 patients, 72 (41%) received CCT and 105 (59%) did not receive CCT. PFS was significantly better for patients in the CCT group compared to that for patients in the non-CCT group (median PFS: 17.0 vs 12.9 months, respectively, P=0.031), whereas the differences in OS were not statistically significant (median OS: 31.6 vs 24.8 months, respectively, P=0.118). The 3- and 5-year OS rates were 33.3% and 20.8% for patients in the CCT group and 27.6% and 6.7% for patients in the non-CCT group, respectively. Multivariate analysis revealed that having a pretreatment carcinoembryonic antigen level <5 ng/mL (P=0.035), having undergone prophylactic cranial irradiation (P<0.001), and having received CCT (P=0.002) could serve as favorable independent prognostic factors for PFS. Multivariate analysis for OS also showed that having undergone PCI (P<0.001) and having received CCT (P=0.006) were independent significant prognostic factors. CONCLUSION: CCT can improve PFS for patients with stage IIIA and IIIB SCLC following CCRT without significantly increasing treatment-related toxicities. PMID- 27703373 TI - The expressions of NEDD9 and E-cadherin correlate with metastasis and poor prognosis in triple-negative breast cancer patients. AB - BACKGROUND: Neural precursor cell expressed, developmentally downregulated 9 (NEDD9), a member of Crk-associated substrate family, is involved in cancer cell adhesion, migration, invasion, and epithelial-mesenchymal transition. E-cadherin is a key event in the cellular invasion during the epithelial-mesenchymal transition mechanism. The aim of this study was to evaluate the association among NEDD9 expression, E-cadherin expression, and survival in triple-negative breast cancer (TNBC) patients. METHODS: NEDD9 and E-cadherin expressions were analyzed by immunohistochemistry in 106 TNBC patients and 120 non-TNBC patients. And the association of clinicopathological factors with survival was analyzed using Kaplan-Meier analysis and Cox regression in TNBC patients. RESULTS: The results revealed that the rate of increased expression of NEDD9 and reduced expression of E-cadherin was significantly higher in TNBC group than that in non-TNBC group (P<0.001, both). Comparison of features between TNBC and non-TNBC groups showed that histological type (P=0.026) and lymph node metastasis (P=0.001) were significantly different. Correlation analysis showed that positive NEDD9 expression and negative E-cadherin expression were significantly correlated with lymph node metastasis and tumor-node-metastasis stage (P<0.05). In addition, the enhanced NEDD9 expression was significantly associated with a reduced 5-year survival for TNBC patients (overall survival [OS]: P=0.013; disease-free survival [DFS]: P=0.021). Negative E-cadherin expression showed a significantly worse 5 year OS and DFS (OS: P=0.011; DFS: P=0.012). Multivariate analysis showed that lymph node metastasis (OS: P=0.006; DFS: P=0.004), tumor-node-metastasis stage (OS: P=0.012; DFS: P=0.001), NEDD9 (OS: P=0.046; DFS: P=0.022), and E-cadherin (OS: P=0.022; DFS: P=0.025) independently predicted a poor prognosis of OS and DFS. Moreover, patients with NEDD9-positive/E-cadherin-negative expression had a significantly worse outcome than other groups (OS: P=0.004; DFS: P=0.001). CONCLUSION: Our finding demonstrated the potential value of NEDD9 and E-cadherin expression levels as prognostic molecular markers and a target for new therapies for TNBC patients. PMID- 27703374 TI - Pretreatment neutrophil-to-lymphocyte ratio as a survival predictor for small cell lung cancer. AB - BACKGROUND: The inflammatory response indexes, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR), have prognostic value for a variety of cancers. However, their prognostic value for small-cell lung cancer (SCLC) has been rarely reported. In this study, we monitored changes of NLR and PLR along with the clinical outcomes in patients with limited-stage and extensive-stage SCLC who received standard treatments. MATERIALS AND METHODS: We retrospectively reviewed the records of 153 patients who were pathologically diagnosed with SCLC and collected their hematological data at different time points during disease and treatment process. Kaplan-Meier analysis and Cox proportional hazards models were used to determine the prognostic significance of NLR and PLR for overall survival (OS) and progression-free survival (PFS). RESULTS: The median OS and PFS for all patients were 23.3 months and 11.0 months, respectively. After applying cutoffs of 3.2 for NLR and 122.7 for PLR, NLR, but not PLR, showed independent prognostic significance. High-NLR group was associated with shorter median OS (high vs low, 18.0 months vs 31.0 months, P<0.01) and shorter PFS (high vs low, 9.3 months vs 13.0 months, P=0.006). The cumulative 3-year OS rate and 3-year PFS rate of high-NLR group versus low-NLR group were 14.3% versus 37.3% and 8.6% versus 22.9%, respectively. In the multivariate analysis, both disease stage and NLR at diagnosis were independent prognostic factors for OS and PFS. CONCLUSION: The NLR at diagnosis showed significant prognostic value for clinical outcomes in SCLC patients treated with chemoradiotherapy. As an effective biomarker of host immune status, NLR could potentially help monitoring disease progression and adjusting treatment plans. PMID- 27703376 TI - A case report and literature review of primary resistant Hodgkin lymphoma: a response to anti-PD-1 after failure of autologous stem cell transplantation and brentuximab vedotin. AB - Hodgkin lymphoma (HL) is a highly curable hematologic malignancy, and ~70% of cases can be cured with combination chemotherapy with or without radiation. However, patients with primary resistant disease have a cure rate of <30%. For such patients, high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is considered to be the standard treatment. If patients fail to respond to ASCT or relapse soon thereafter, they usually receive another ASCT, allogeneic stem cell transplantation or treatment with novel agents. This case report presents the case of a 54-year-old patient with primary resistant HL who received single-agent treatment, brentuximab vedotin, after ASCT relapse. Despite treatment with brentuximab vedotin, the disease continued to progress. In patients with such highly resistant disease, the treatment options are limited. Depending on the physical condition and the willingness of the patient, pembrolizumab, a programmed cell death protein-1 inhibitor, can be given as salvage therapy. But, out of our expectation, the patient achieved a very good partial response after four cycles of pembrolizumab. No serious adverse events were observed with pembrolizumab treatment. This case provides support for a new and effective strategy for treating primary resistant Hodgkin lymphoma. PMID- 27703375 TI - Prognostic value of decreased microRNA-133a in solid cancers: a meta-analysis. AB - OBJECTIVE: Increasing evidence indicates that the decreased expression of microRNA-133a (miR-133a) may be correlated with poor survival for cancer patients. Thus, we performed this meta-analysis to evaluate the prognostic value of decreased miR-133a in solid cancers. METHODS: Eligible studies were gathered by searching on PubMed, Web of Science, and Embase. Using the STATA 12.0 software, the pooled hazard ratios (HRs) and their corresponding 95% confidence intervals (CIs) for total and subgroup analyses were calculated to investigate the possible correlation between decreased miR-133a and overall survival (OS) of patients with cancer. RESULTS: Ten studies were enrolled in this meta-analysis. The pooled result showed that decreased expression of miR-133a predicted poor OS in solid cancer patients (HR =1.62, 95% CI: 1.16-2.24, P=0.004). Compared with the total pooled HR, further analyses indicated that the subgroups of digestive system neoplasms (HR =1.73, 95% CI: 1.20-2.51, P=0.003), frozen tissue preservation (HR =1.89, 95% CI: 1.41-2.53, P<0.001), and multivariate analysis (HR =2.07, 95% CI: 1.42-3.02, P<0.001) exhibited stronger connection between decreased miR-133a expression and OS outcome. CONCLUSION: This meta-analysis suggested that decreased miR-133a was associated with poor OS in patients with solid cancer. Because of the data in our study are limited, additional studies are required to verify the poor prognosis of decreased miR-133a in solid tumors. PMID- 27703377 TI - Apparent diffusion coefficient values detected by diffusion-weighted imaging in the prognosis of patients with locally advanced esophageal squamous cell carcinoma receiving chemoradiation. AB - PURPOSE: Previous studies have demonstrated that apparent diffusion coefficient (ADC) values measured by magnetic resonance imaging have prognostic value in patients with esophageal squamous cell carcinoma (ESCC). However, the role of ADC needs to be validated in a cohort of Chinese ESCC patients. This study assessed the role of ADC in predicting the outcome of patients with ESCC treated only by chemoradiation in the People's Republic of China. PATIENTS AND METHODS: Seventy three patients with local advanced ESCC were retrospectively analyzed in this study; none of the patients underwent surgery before or after chemoradiation. The ADC values of the primary tumors were determined by magnetic resonance imaging. The ADC values were then correlated with clinicopathological and other radiological parameters. Survival analysis was carried out to determine if ADC had an impact on survival of these patients. RESULTS: The median ADC value of the esophageal cancer tissue was 1.256*10-3 mm2/sec (range: 0.657-2.354*10-3 mm2/sec, interquartile range 0.606*10-3 mm2/sec). No clinicopathological or radiological parameters were associated with the ADC values except the sites of tumor tissues. ADC <1.076*10-3 mm2/sec predicted significantly worse survival in patients with ESCC (12.9 months vs undefined, P=0.0108). CONCLUSION: The ADC value is a potent prognostic factor which can be used to predict the outcome of patients with ESCC treated only by chemoradiation. PMID- 27703378 TI - A clear cell adenocarcinoma of the gallbladder with hepatoid differentiation: case report and review of literature. AB - An 80-year-old male was referred to our department for a gallbladder mass. He denied any history of alcohol consumption or cholecystitis and smoking. Hepatitis B surface antigen test and antihepatitis C antibody test were found to be negative. Serum carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen were elevated (CA19-9 was 59.92 U/mL and carcinoembryonic antigen was 12.64 ng/mL), whereas alpha-fetoprotein was below the normal limit (2.46 ng/mL). Computed tomography scan revealed a solid mass with measurements of 4.6*5.6*7.1 cm, which nearly filled the whole gallbladder space. Radical cholecystectomy, including segments IV B and V of the liver and lymphadenectomy, was performed. The neoplasm in gallbladder was completely resected, and the patient obtained a negative margin. Histological and immunohistochemical profile suggested a clear cell adenocarcinoma of the gallbladder with hepatoid differentiation. After reviewing the literature, we reported that this case is the first identified case of cell adenocarcinoma of the gallbladder with extensive hepatoid differentiation. However, clinical features of clear cell adenocarcinoma with hepatoid differentiation remain unclear due to the extremely rare incidence. There was no indication of adjuvant chemotherapy and no literature has been reported on the application of chemotherapy. This case showed a promising clinical outcome after curative resection, which indicated that surgical treatment could be potentially considered for suitable patients. PMID- 27703379 TI - Anatomic distribution of supraclavicular lymph node in patients with esophageal cancer. AB - PURPOSE: Definitive chemoradiation therapy remains the standard of care for patients with localized esophageal carcinoma who choose nonsurgical management. However, there is no consensus regarding delineation of the nodal clinical target volume (CTVn), especially for lower cervical lymph nodes. This study aimed to map the location of metastatic supraclavicular lymph nodes in thoracic esophageal carcinoma patients with supraclavicular node involvement and generate an atlas to delineate the CTVn for elective nodal radiation of esophageal squamous cell carcinoma. PATIENTS AND METHODS: In this study, the supraclavicular regional lymph node was further divided into four subgroups. The locations of the involved supraclavicular nodes for all patients were then transferred onto a template computed tomography (CT) image. A volume probability map was then generated with nodal volumes, and was displayed on the template CT to provide a visual impression of nodal frequencies and anatomic distribution. RESULTS: We identified 154 supraclavicular nodal metastases based on CT image in 96 patients. Of these, 29.2% were located in group I region, 59.7% in group II region, 10.4% in group III region, and 0.7% in group IV region. CONCLUSION: On the basis of our study, we suggest that the appropriate radiation field of CTVn should include the group I and II regions and the CTVn exterior margin along the lateral side of the internal jugular vein may be suitable. PMID- 27703380 TI - Evaluation of c-Met, HGF, and HER-2 expressions in gastric carcinoma and their association with other clinicopathological factors. AB - BACKGROUND: Met and HER-2 are proto-oncogenes encoding receptor tyrosine kinase c Met and HER-2, respectively. Hepatocyte growth factor (HGF) is a ligand of c-Met. The frequency of c-Met, HGF, and HER-2 expressions in gastric cancer and their association with other clinicopathological factors have not been fully understood. PATIENTS AND METHODS: Patients with stage 1-4 disease were analyzed. Expressions of c-Met, HGF, and HER-2 were examined using immunohistochemistry. RESULTS: A total of 143 patients, 97 males and 46 females, were included. C-Met scores were 3(+) in 31.5%, 2(+) in 27.3%, and 1(+) in 10.5% of the patients. There was no statistically significant difference in age, sex, tumor location, differentiation, Lauren classification, TNM staging, presence of distant metastasis, depth of tumor invasion (T), lymphovascular invasion, and survival between c-Met subgroups. Overall HGF positivity was 20.6%. HER-2 scores were 3(+) in 9.1%, 2(+) in 9.8%, and 1(+) in 16.1% of the patients. HER-2 overexpression was associated with better differentiation, intestinal subtype, and advanced stage. C-Met overexpressions were 84.6% in the HER-2-overexpression-positive group and 56.2% in the HER-2-overexpression-negative group. There were no statistically significant differences in survival between the high c-Met expression-positive and -negative stage 3 and stage 4 patients and between the HGF-positive and -negative groups. The mean survival was 11.6+/-6.3 months in the HER-2-overexpression-positive stage 4 group and 11.9+/-6.8 months in the HER-2 overexpression-negative stage 4 group. There were no statistically significant differences in survival between the two groups. CONCLUSION: c-Met was not associated with any prognostic factors in gastric cancer. HER-2 was associated with better differentiation, intestinal subtype, advanced stage, and c-Met overexpression. PMID- 27703381 TI - An evaluation of the diagnostic efficacy of fine needle aspiration biopsy in patients operated for a thyroid nodular goiter. AB - BACKGROUND: Thyroid cancer (TC) comprises 1% of all carcinomas and is the most common malignancy of the endocrine system. The disease is more common in women, with its peak morbidity observed in 40-50-year-old patients. The main risk factors include radiation, iodine deficiency, hereditary background, and genetic mutations. Among all diagnosed thyroid nodules, 5%-30% will evolve into cancer. The gold-standard procedure in the preoperative evaluation of a nodular goiter, apart from ultrasonography, is fine needle aspiration (FNA) biopsy. The FNA biopsy is favored for its simplicity, safety, and high specificity and sensitivity rates. AIM: The aim of our study was to evaluate the clinical efficacy of FNA based on the patients' register. MATERIALS AND METHODS: In the Department of Surgery at the 4th Military Teaching Hospital in Wroclaw, 2,133 patients underwent thyroid surgery for thyroid goiter between 1996 and 2015. One hundred and eight cases of TC were diagnosed and of these, 66 patients had a preoperative FNA. RESULTS: Fourteen FNA biopsies (21%) revealed cancer, all of which were confirmed in the postoperative histopathology, although six cases of FNA-diagnosed cancer revealed a different histological type postoperatively. Eighteen FNA biopsies (27%) were suspected of being malignant. A disturbingly high rate of "benign" FNA biopsies (32 cases; 48%) revealed TC after surgery. CONCLUSION: It is of great importance that the quality and quantity of FNA biopsies that are performed have been improved, especially due to the wide adoption of the Bethesda cytological evaluation system. FNA biopsy remains an obligatory and valuable diagnostic tool in thyroid nodules, but it is still insufficient as a standard procedure. A preoperative biopsy should always be related to all the available clinical data in order to provide the best treatment option for each patient individually. PMID- 27703384 TI - Economic evaluation of obinutuzumab in combination with chlorambucil in first line treatment of patients with chronic lymphocytic leukemia in Spain. AB - OBJECTIVE: To evaluate the cost-effectiveness of obinutuzumab in combination with chlorambucil (GClb) versus rituximab plus chlorambucil (RClb) in the treatment of adults with previously untreated chronic lymphocytic leukemia (CLL) and with comorbidities that make them unsuitable for full-dose fludarabine-based therapy, from the perspective of the Spanish National Health System. METHODS: A Markov model was developed with three mutually exclusive health states: progression-free survival (with or without treatment), progression, and death. Survival time for the two treatments was modeled based on the results of CLL11 clinical trial and external sources. Each health state was associated with a utility value and direct medical costs. The utilities were obtained from a utility elicitation study conducted in the UK. Costs and general background mortality data were obtained from published Spanish sources. Deterministic and probabilistic analyses were conducted, with a time frame of 20 years. The health outcomes were measured as life years (LYs) gained and quality-adjusted life years (QALYs) gained. Efficiency was measured as the cost per LY or per QALY gained of the most effective regimen. RESULTS: In the deterministic base case analysis, each patient treated with GClb resulted in 0.717 LYs gained and 0.673 QALYs gained versus RClb. The cost per LY and per QALY gained with GClb versus RClb was ?23,314 and ?24,838, respectively. The results proved stable in most of the univariate and probabilistic sensitivity analyses, with a probabilistic cost per QALY gained of ?24,734 (95% confidence interval: ?21,860-28,367). CONCLUSION: Using GClb to treat patients with previously untreated CLL for whom full-dose fludarabine-based therapy is unsuitable allows significant gains in terms of LYs and QALYs versus treatment with RClb. Treatment with GClb versus RClb can be regarded as efficient when considered the willingness to pay thresholds commonly used in Spain. PMID- 27703383 TI - Aspergillus fumigatus in the cystic fibrosis lung: pros and cons of azole therapy. AB - Aspergillus fumigatus is the main fungus cultured in the airways of patients with cystic fibrosis (CF). Allergic bronchopulmonary aspergillosis occurs in ~10% of CF patients and is clearly associated with airway damage and lung function decline. The effects of A. fumigatus colonization in the absence of allergic bronchopulmonary aspergillosis are less well established. Retrospective clinical studies found associations of A. fumigatus-positive cultures with computed tomography scan abnormalities, greater risk of CF exacerbations and hospitalizations, and/or lung function decline. These findings were somewhat variable among studies and provided only circumstantial evidence for a role of A. fumigatus colonization in CF lung disease progression. The availability of a growing number of oral antifungal triazole drugs, together with the results of nonrandomized case series suggesting positive effects of azole therapies, makes it tempting to treat CF patients with these antifungal drugs. However, the only randomized controlled trial that has used itraconazole in CF patients showed no significant benefit. Because triazoles may have significant adverse effects and drug interactions, and because their prolonged use has been associated with the emergence of azole-resistant A. fumigatus isolates, it remains unclear whether or not CF patients benefit from azole therapy. PMID- 27703382 TI - Chronic hypersensitivity pneumonitis. AB - Hypersensitivity pneumonitis (HSP) is a common interstitial lung disease resulting from inhalation of a large variety of antigens by susceptible individuals. The disease is best classified as acute and chronic. Chronic HSP can be fibrosing or not. Fibrotic HSP has a large differential diagnosis and has a worse prognosis. The most common etiologies for HSP are reviewed. Diagnostic criteria are proposed for both chronic forms based on exposure, lung auscultation, lung function tests, HRCT findings, bronchoalveolar lavage, and biopsies. Treatment options are limited, but lung transplantation results in greater survival in comparison to idiopathic pulmonary fibrosis. Randomized trials with new antifibrotic agents are necessary. PMID- 27703385 TI - Patient-level costs of major cardiovascular conditions: a review of the international literature. AB - OBJECTIVE: Robust cost estimates of cardiovascular (CV) events are required for assessing health care interventions aimed at reducing the economic burden of major adverse CV events. This review synthesizes international cost estimates of CV events. METHODS: MEDLINE database was searched electronically for English language studies published during 2007-2012, with cost estimates for CV events of interest - unstable angina, myocardial infarction, heart failure, stroke, and CV revascularization. Included studies provided at least one estimate of patient level direct costs in adults for any identified country. Information on study characteristics and cost estimates were collected. All costs were adjusted for inflation to 2013 values. RESULTS: Across the 114 studies included, the average cost was US $6,466 for unstable angina, $11,664 for acute myocardial infarction, $11,686 for acute heart failure, $11,635 for acute ischemic stroke, $37,611 for coronary artery bypass graft, and $13,501 for percutaneous coronary intervention. The ranges for cost estimates varied widely across countries with US cost estimate being at least twice as high as European Union costs for some conditions. Few studies were found on populations outside the US and European Union. CONCLUSION: This review showed wide variation in the cost of CV events within and across countries, while showcasing the continuing economic burden of CV disease. The variability in costs was primarily attributable to differences in study population, costing methodologies, and reporting differences. Reliable cost estimates for assessing economic value of interventions in CV disease are needed. PMID- 27703386 TI - A hospital cost analysis of a fibrin sealant patch in soft tissue and hepatic surgical bleeding. AB - BACKGROUND: Despite hemostat use, uncontrolled surgical bleeding is prevalent. Drawbacks of current hemostats include limitations with efficacy on first attempt and suboptimal ease-of-use. Evarrest(r) is a novel fibrin sealant patch that has demonstrated high hemostatic efficacy compared with standard of care across bleeding severities. The objective of this study was to conduct a hospital cost analysis of the fibrin sealant patch versus standard of care in soft tissue and hepatic surgical bleeding. METHODS: The analysis quantified the 30-day costs of each comparator from a hospital perspective. Published US unit costs were applied to resource use (ie, initial treatment, retreatment, operating time, hospitalization, transfusion, and ventilator) reported in four trials. A "surgical" analysis included resources clinically related to the hemostatic benefit of the fibrin sealant patch, whereas a "hospital" analysis included all resources reported in the trials. An exploratory subgroup analysis focused solely on coagulopathic patients defined by abnormal blood test results. RESULTS: The surgical analysis predicted cost savings of $54 per patient with the fibrin sealant patch compared with standard of care (net cost impact: -$54 per patient; sensitivity range: -$1,320 to $1,213). The hospital analysis predicted further cost savings with the fibrin sealant patch (net cost impact of -$2,846 per patient; sensitivity range: -$1,483 to -$5,575). Subgroup analyses suggest that the fibrin sealant patch may provide dramatic cost savings in the coagulopathic subgroup of $3,233 (surgical) and $9,287 (hospital) per patient. Results were most sensitive to operating time and product units. CONCLUSION: In soft tissue and hepatic problematic surgical bleeding, the fibrin sealant patch may result in important hospital cost savings. PMID- 27703387 TI - Cost-effectiveness of dipeptidyl peptidase-4 inhibitor monotherapy in elderly type 2 diabetes patients in Thailand. AB - BACKGROUND: The management of type 2 diabetes mellitus (T2DM) in elderly population poses many challenges. Dipeptidyl peptidase-4 (DPP-4) inhibitors show particular promise due to excellent tolerability profiles, low risk of hypoglycemia, and little effect on body weight. This study evaluated, from the health care system's perspective, the long-term cost-effectiveness of DPP-4 inhibitor monotherapy vs metformin and sulfonylurea (SFU) monotherapy in Thai elderly T2DM patients. METHODS: The clinical efficacy was estimated from a systematic review and meta-analysis. Baseline cohort characteristics and cost parameters were obtained from published studies and hospital databases in Thailand. A validated IMS CORE Diabetes Model version 8.5 was used to project clinical and economic outcomes over a lifetime horizon using a 3% annual discount rate. Costs were expressed in 2014 Thai Baht (THB) (US dollar value). Incremental cost-effectiveness ratios were calculated. Base-case assumptions were assessed through several sensitivity analyses. RESULTS: For treating elderly T2DM patients, DPP-4 inhibitors were more expensive and less effective, ie, a dominated strategy, than the metformin monotherapy. Compared with SFU, treatment with DPP-4 inhibitors gained 0.031 more quality-adjusted life years (QALYs) at a total cost incurred over THB113,701 or US$3,449.67, resulting in an incremental cost-effectiveness ratio of THB3.63 million or US$110,133.50 per QALY. At the acceptable Thai ceiling threshold of THB160,000/QALY (US$4,854.37/QALY), DPP-4 inhibitors were not a cost-effective treatment. CONCLUSION: DPP-4 inhibitor monotherapy is not a cost-effective treatment for elderly T2DM patients compared with metformin monotherapy and SFU monotherapy, given current resource constraints in Thailand. PMID- 27703388 TI - Cost-effectiveness analysis of online hemodiafiltration versus high-flux hemodialysis. AB - BACKGROUND: Clinical studies suggest that hemodiafiltration (HDF) may lead to better clinical outcomes than high-flux hemodialysis (HF-HD), but concerns have been raised about the cost-effectiveness of HDF versus HF-HD. Aim of this study was to investigate whether clinical benefits, in terms of longer survival and better health-related quality of life, are worth the possibly higher costs of HDF compared to HF-HD. METHODS: The analysis comprised a simulation based on the combined results of previous published studies, with the following steps: 1) estimation of the survival function of HF-HD patients from a clinical trial and of HDF patients using the risk reduction estimated in a meta-analysis; 2) simulation of the survival of the same sample of patients as if allocated to HF HD or HDF using three-state Markov models; and 3) application of state-specific health-related quality of life coefficients and differential costs derived from the literature. Several Monte Carlo simulations were performed, including simulations for patients with different risk profiles, for example, by age (patients aged 40, 50, and 60 years), sex, and diabetic status. Scatter plots of simulations in the cost-effectiveness plane were produced, incremental cost effectiveness ratios were estimated, and cost-effectiveness acceptability curves were computed. RESULTS: An incremental cost-effectiveness ratio of ?6,982/quality adjusted life years (QALY) was estimated for the baseline cohort of 50-year-old male patients. Given the commonly accepted threshold of ?40,000/QALY, HDF is cost effective. The probabilistic sensitivity analysis showed that HDF is cost effective with a probability of ~81% at a threshold of ?40,000/QALY. It is fundamental to measure the outcome also in terms of quality of life. HDF is more cost-effective for younger patients. CONCLUSION: HDF can be considered cost effective compared to HF-HD. PMID- 27703390 TI - Splenosis involving the gastric fundus, a rare cause of massive upper gastrointestinal bleeding: a case report and review of the literature. AB - Splenosis, the autotransplantation of splenic tissue following splenic trauma, is uncommonly clinically significant. Splenosis is typically diagnosed incidentally on imaging or at laparotomy and has been mistakenly attributed to various malignancies and pathological conditions. On the rare occasion when splenosis plays a causative role in a pathological condition, a diagnostic challenge may ensue that can lead to a delay in both diagnosis and treatment. The following case report describes a patient presenting with a massive upper gastrointestinal bleed resulting from arterial enlargement within the gastric fundus secondary to perigastric splenosis. The cause of the bleeding was initially elusive and this case highlights the importance of a thorough clinical history when faced with a diagnostic challenge. Treatment options, including the successful use of transarterial embolization in this case, are also presented. PMID- 27703389 TI - Ineffective esophageal motility and the vagus: current challenges and future prospects. AB - Ineffective esophageal motility (IEM) is characterized by low to very low amplitude propulsive contractions in the distal esophagus, hence primarily affecting the smooth muscle part of the esophagus. IEM is often found in patients with dysphagia or heartburn and is commonly associated with gastroesophageal reflux disease. IEM is assumed to be associated with ineffective bolus transport; however, this can be verified using impedance measurements or evaluation of a barium coated marshmallow swallow. Furthermore, water swallows may not assess accurately the motor capabilities of the esophagus, since contraction amplitude is strongly determined by the size and consistency of the bolus. The "peristaltic reserve" of the esophagus can be evaluated by multiple rapid swallows that, after a period of diglutative inhibition, normally give a powerful peristaltic contraction suggestive of the integrity of neural orchestration and smooth muscle action. The amplitude of contraction is determined by a balance between intrinsic excitatory cholinergic, inhibitory nitrergic, as well as postinhibition rebound excitatory output to the musculature. This is strongly influenced by vagal efferent motor neurons and this in turn is influenced by vagal afferent neurons that send bolus information to the solitary nucleus where programmed activation of the vagal motor neurons to the smooth muscle esophagus is initiated. Solitary nucleus activity is influenced by sensory activity from a large number of organs and various areas of the brain, including the hypothalamus and the cerebral cortex. This allows interaction between swallowing activities and respiratory and cardiac activities and allows the influence of acute and chronic emotional states on swallowing behavior. Interstitial cells of Cajal are part of the sensory units of vagal afferents, the intramuscular arrays, and they provide pacemaker activity to the musculature that can generate peristalsis in the absence of innervation. This indicates that a low-amplitude esophageal contraction, observed as IEM, can be caused by a multitude of factors, and therefore many pathways can be potentially explored to restore normal esophageal peristalsis. PMID- 27703391 TI - Cigarette smoking adversely affects disease activity and disease-specific quality of life in patients with Crohn's disease at a tertiary referral center. AB - PURPOSE: Smoking has a negative impact on disease activity in Crohn's disease (CD). Smoking may also affect the quality of life, but this has not been evaluated using validated measures over time. We assessed the relationship between smoking and disease-specific quality of life over time in a tertiary referral inflammatory bowel disease cohort. PATIENTS AND METHODS: Retrospective cohort study from July 2004 to July 2009 in patients with CD identified from the University of Maryland, Baltimore, Institutional Review Board-approved University of Maryland School of Medicine Inflammatory Bowel Disease Program database. Smoking status was classified as current, former, and never. Age was categorized as <40 years, 40-59 years, and >=60 years. Index visit disease activity and quality of life was measured with the Harvey-Bradshaw index, and the Short Inflammatory Bowel Disease Questionnaire (SIBDQ). Repeated measures linear regression was used to assess the association between smoking and quality of life over time after adjustment for confounding variables. RESULTS: A total of 608 patients were included, of whom 42% were male; 80% were Caucasian; 22% were current smokers; 24% were former smokers; and 54% were never smokers. Over time, adjusted Harvey-Bradshaw index scores declined in all patients, but current smokers had consistently higher scores. After adjustment for sex, age, and disease duration, never smokers had higher mean SIBDQ scores at index visit compared to former and current smokers (P<0.0001); all increased over time but SIBDQ scores for never smokers remained consistently highest. CONCLUSION: Smoking has a negative impact on disease activity and quality of life in patients with CD. Prospects of improved disease activity and quality of life should be proposed as an additional incentive to encourage smoking cessation in patients with CD. PMID- 27703393 TI - Effectiveness of low-dose intravenous ketamine to attenuate stress response in patients undergoing emergency cesarean section with spinal anesthesia. AB - PURPOSE: Cesarean section is a surgical procedure. Surgical procedures will induce stress responses, which may have negative impact on postoperative recovery. Ketamine plays a role in the homeostatic regulation of inflammatory response in order to attenuate stress response. We tried to determine the effectiveness of low-dose intravenous ketamine to attenuate stress response in patients undergoing emergency cesarean section with spinal anesthesia. PATIENTS AND METHODS: Thirty-six pregnant women undergoing emergency cesarean section with spinal anesthesia were randomly divided into two groups (n=18). Ketamine 0.3 mg/kg (KET group) or NaCl 0.9% (NS group) was administered intravenously before the administration of spinal anesthesia. C-reactive protein (CRP) and neutrophil levels were measured preoperatively and postoperatively. RESULTS: Elevation of CRP stress response was lower in the KET group and significantly different (P<=0.05) from that in the NS group. Neutrophil level was elevated in both the groups and hence not significantly different from each other (P>0.05). Postoperative visual analog scale pain score was not significantly different between the two groups (P>0.05), but there was a statistically significant (P<=0.05) positive and weak correlation between visual analog scale and CRP level postoperatively. CONCLUSION: Low-dose intravenous ketamine effectively attenuates the CRP stress response in patients undergoing emergency cesarean section with spinal anesthesia. PMID- 27703392 TI - The treatment of nonunions with application of BMP-7 increases the expression pattern for angiogenic and inflammable cytokines: a matched pair analysis. AB - The local application of bone morphogenetic protein-7 (BMP-7) in combination with the transplantation of autologous bone graft improves the outcome in nonunion treatment; however, the specific reasons remain unclear. In this study, we sought to determine if the local application of BMP-7 contributes to improved bone regeneration in nonunion therapy by modulation of the angiogenic and inflammable cytokine expression patterns of the early inflammation response. Therefore, we utilized the analysis of serological cytokine expression patterns. As a matched pair analysis, best-fitting patients who were treated with transplantation of autologous bone graft (G1, n=10) were compared with patients who were treated with additional application of BMP-7 (G2, n=10). The changes in the cytokine expression patterns were monitored and correlated to clinical data of bone healing. Significant differences in angiogenesis potential (vascular endothelial growth factor [VEGF] serum levels) could be found in the first days after surgery (P<0.05). Furthermore, the increase and absolute amount of VEGF levels in the BMP 7 group were considerably higher than in the control group during the first 2 weeks after surgery. The expression pattern of inflammable cytokines showed noticeable differences in the time point of significant elevated levels, in particular, inflammable cytokines showed an earlier peak in G2. Furthermore, interleukin-6 was significantly elevated within the first week only, comparing G2 to G1 (P<0.05). Our findings indicate that BMP-7 induces an early and more intense expression of VEGF via a direct and postulated indirect pathway, thereby providing a favorable environment for bone healing. Moreover, application of BMP 7 leads to an earlier expression of known proinflammatory cytokines. The results of this study show that application of BMP-7 leads to costimulatory effect on both angiogenic and inflammable cytokine expression patterns that may serve as a possible stimulus for bone regeneration. PMID- 27703394 TI - Survey of pain specialists regarding conversion of high-dose intravenous to neuraxial opioids. AB - The conversion of high-dose intravenous (IV) opioids to an equianalgesic epidural (EP) or intrathecal (IT) dose is a common clinical dilemma for which there is little evidence to guide practice. Expert opinion varies, though a 100 IV:10:EP:1 IT conversion ratio is commonly cited in the literature, especially for morphine. In this study, the authors surveyed 724 pain specialists to elucidate the ratios that respondents apply to convert high-dose IV morphine, hydromorphone, and fentanyl to both EP and IT routes. Eighty-three respondents completed the survey. Conversion ratios were calculated and entered into graphical scatter plots. The data suggest that there is wide variation in how pain specialists convert high dose IV opioids to EP and IT routes. The 100 IV:10 EP:1 IT ratio was the most common answer of survey respondent, especially for morphine, though also for hydromorphone and fentanyl. Furthermore, more respondents applied a more aggressive conversion strategy for hydromorphone and fentanyl, likely reflecting less spinal selectivity of those opioids compared with morphine. The authors conclude that there is little consensus on this issue and suggest that in the absence of better data, a conservative approach to opioid conversion between IV and neuraxial routes is warranted. PMID- 27703395 TI - Using social media to challenge unwarranted clinical variation in the treatment of chronic noncancer pain: the "Brainman" story. AB - There is a substantial clinical variation in the contemporary treatment of chronic noncancer pain reflecting different explanatory models and treatment emphasis. Hunter Integrated Pain Service and collaborators developed three key messaging videos outlining the foundations of chronic pain treatment, thus challenging unwarranted clinical variation and calling for greater therapeutic consistency. The videos were released on YouTube as a low-cost public health intervention. Each video used an evidenced informed script appropriate for low literacy and a cartoonist to provide matching images. The whole-person approach emphasized the role of the nervous system and active self-management approaches over passively received medical treatments. The first video was launched on YouTube in August 2011 and made freely available through a Creative Commons license. Multisource feedback led to refinement of key messages using a broader advisory group. Two further videos were launched on a dedicated YouTube channel in October 2014 and circulated through varied professional and consumer networks. All videos were widely viewed on YouTube, utilized by diverse health care organizations, and independently translated into multiple languages. They were embedded in multiple health-related websites. The first video "Understanding pain in less than 5 minutes" is known to have been translated into 15 languages by other health care organizations. The subsequent two videos (Brainman stops his opioids, and Brainman chooses) were translated into German and subtitled in French and Japanese. When the organization hosting the first video ceased operation in 2015 due to changes in primary health care funding, the video had received >700,000 views. Each of the three videos continues to receive ~1,500 views per month on YouTube. Release of evidence-informed key messages via YouTube is a simple method of challenging clinical variation and providing education about chronic pain across the health care system and community. PMID- 27703396 TI - Epilepsy during pregnancy: focus on management strategies. AB - In the US, more than one million women with epilepsy are of childbearing age and have over 20,000 babies each year. Patients with epilepsy who become pregnant are at risk of complications, including changes in seizure frequency, maternal morbidity and mortality, and congenital anomalies due to antiepileptic drug exposure. Appropriate management of epilepsy during pregnancy may involve frequent monitoring of antiepileptic drug serum concentrations, potential preconception switching of antiepileptic medications, making dose adjustments, minimizing peak drug concentration with more frequent dosing, and avoiding potentially teratogenic medications. Ideally, preconception planning will be done to minimize risks to both the mother and fetus during pregnancy. It is important to recognize benefits and risks of current and emerging therapies, especially with revised pregnancy labeling in prescription drug product information. This review will outline risks for epilepsy during pregnancy, review various recommendations from leading organizations, and provide an evidence-based approach for managing patients with epilepsy before, during, and after pregnancy. PMID- 27703397 TI - Hyperglycemia in pregnancy: prevalence, impact, and management challenges. AB - Gestational diabetes mellitus (GDM) is one of the most common medical conditions in pregnancy, and the prevalence is growing with increasing rates of women of advanced age becoming pregnant and the increasing prevalence of maternal obesity and inactivity. GDM is associated with an increased risk of maternal and infant short- and long-term ill-health. There is a positive linear association between increasing maternal glucose at oral glucose tolerance testing and risk of important perinatal outcomes, including cesarean section, large for gestational age, and infant adiposity. A "step-up" approach, where diet and lifestyle information is provided followed by pharmacological interventions as required to control and reduce hyperglycemia, is effective at reducing the risk of macrosomia, but treatment of GDM will increase demand on health services. There is limited evidence to suggest which identification strategy is best or what thresholds should be used to diagnose GDM or what the effects of different diagnostic strategies have on short- or long-term maternal and offspring outcomes. Trials of interventions in pregnancy aimed at preventing GDM have not demonstrated a benefit; therefore, trials are needed to evaluate interventions aimed at optimizing the health of all women of childbearing age, outside of pregnancy. A consistent, evidence-based, sustained approach to supporting women to live healthily, including the achievement of a normal body mass index before and after pregnancy, is urgently needed. PMID- 27703399 TI - Acute chest pain after bench press exercise in a healthy young adult. AB - Bench press exercise, which involves repetitive lifting of weights to full arm extension while lying supine on a narrow bench, has been associated with complications ranging in acuity from simple pectoral muscle strain, to aortic and coronary artery dissection. A 39-year-old man, physically fit and previously asymptomatic, presented with acute chest pain following bench press exercise. Diagnostic evaluation led to the discovery of critical multivessel coronary occlusive disease, and subsequently, highly elevated levels of lipoprotein (a). Judicious use of ancillary testing may identify the presence of "high-risk" conditions in a seemingly "low-risk" patient. Emergency department evaluation of the young adult with acute chest pain must take into consideration an extended spectrum of potential etiologies, so as to best guide appropriate management. PMID- 27703400 TI - Body surface area: a predictor of response to red blood cell transfusion. AB - A current focus of transfusion medicine is a judicious strategy in transfusion of blood products. Unfortunately, our ability to predict hemoglobin (Hgb) response to transfusion has been limited. The objective of this study was to determine variability of response to red blood cell transfusion and to predict which patients will have an Hgb rise higher or lower than that predicted by the long standing convention of "one and three". This was a retrospective chart review in a single hospital. Data for 167 consecutive patient encounters were reviewed. The dataset was randomly divided into derivation and validation subsets with no significant differences in characteristics. DeltaHgb was defined as posttransfusion Hgb minus pre-transfusion Hgb per red blood cell unit. We classified all the patients in both the subsets as "high responders" (DeltaHgb >1 g/dL) or as "low responders" (DeltaHgb <=1 g/dL). In univariate analysis, age, sex, body weight, estimated blood volume, and body surface area were significantly associated with response category (P<0.05). Different multivariate regression models were tested using the derivation subset. The probability of being a high responder was best calculated using the logarithmic formula eH / (1 + eH), where H is B0 + (B1 * variable 1) + (B2 * variable 2). Bis are coefficients of the models. On validation, the model H=6.5-(3.3 * body surface area), with the cutoff probability of 0.5, was found to correctly classify patients into high and low responders in 69% of cases (sensitivity 84.6%, specificity 43.8%). This model may equip clinicians to make more appropriate transfusion decisions and serve as a springboard for further research in transfusion medicine.

AB - INTRODUCTION: Job satisfaction is a multidimensional, enduring, important, and much-researched concept in the field of organizational behavior and has been identified as recognition in one's field of work, level of salary, opportunities for promotion, and achievement of personal goals. Job satisfaction directly affects the labor market behavior and economic efficiency by means of the impact on productivity and turnover of staff. The aim of this study was to assess the satisfaction level of pharmacy professionals in Mekelle city. METHODS: This institution-based cross-sectional study was conducted as a survey and only included voluntary participants. Those participants who did not volunteer to participate were excluded from the study. A structured questionnaire was used as a data collection tool; it was developed from different literature in the English language, and then the original tool was translated to the local language for the purpose of understanding. RESULTS: In Mekelle, ~100 pharmacy professionals work in private medicine retail outlets. From those, only 60 volunteered to participate in this study. Significant difference in job satisfaction and job stress were observed between those working full-time and part-time, with P-values of 0.031 and 0.021, respectively. CONCLUSION: From the findings of the current study, it can be concluded that around two-thirds of pharmacy professionals in Mekelle city were satisfied with their professional practice. PMID- 27703398 TI - Cystic fibrosis transmembrane conductance regulator modulators in cystic fibrosis: current perspectives. AB - Mutations of the CFTR gene cause cystic fibrosis (CF), the most common recessive monogenic disease worldwide. These mutations alter the synthesis, processing, function, or half-life of CFTR, the main chloride channel expressed in the apical membrane of epithelial cells in the airway, intestine, pancreas, and reproductive tract. Lung disease is the most critical manifestation of CF. It is characterized by airway obstruction, infection, and inflammation that lead to fatal tissue destruction. In spite of great advances in early and multidisciplinary medical care, and in our understanding of the pathophysiology, CF is still considerably reducing the life expectancy of patients. This review highlights the current development in pharmacological modulators of CFTR, which aim at rescuing the expression and/or function of mutated CFTR. While only Kalydeco(r) and Orkambi(r) are currently available to patients, many other families of CFTR modulators are undergoing preclinical and clinical investigations. Drug repositioning and personalized medicine are particularly detailed in this review as they represent the most promising strategies for restoring CFTR function in CF. PMID- 27703404 TI - Serological evidence of equine influenza virus in horse stables in Kaduna, Nigeria. AB - Equine influenza virus (EIV) is a major cause of acute respiratory diseases in horses in most parts of the world that results in severe economic losses. Information on the epidemiology of EIV in tropical Africa is scanty. An enzyme linked immunosorbent assay (ELISA) was used to detect the presence of influenza A virus nucleoprotein (NP) in 284 horse sera in Kaduna State, Northern Nigeria. The ELISA-positive sera were further examined for hemagglutination inhibition (HI) antibodies to two strains each of H3N8 and H7N3 subtypes of influenza A virus. The results showed that antibodies against influenza A virus nucleoprotein were detected in 60.9% (173 of 284) of horses examined by NP-ELISA. Equine H3 and H7 subtypes were detected in 60% (21 of 35) and 20% (7 of 35) of horse sera respectively across the stables. Adequate quarantine of all imported horses, a national equine influenza surveillance plan and an appropriate EIV control program in Nigeria are recommended to safeguard the large horse population. PMID- 27703403 TI - Epidemiology of racing injuries in Thoroughbred racehorses with special reference to bone fractures: Japanese experience from the 1980s to 2000s. AB - This report describes the descriptive epidemiology of racing fractures that occurred from the 1980s to 2000s on racetracks of the Japan Racing Association (JRA). The incidence of racehorse fractures during flat racing was approximately 1-2%. Fractures occurring during a race are more likely to occur in a forelimb. Fractures mostly occur at the third and fourth corners of oval tracks and on the home stretch. They also occur more frequently at the time of changing the leading limb. Comparison of the incidence of racing fracture between before and after reconstruction of the geometrical configuration of a racetrack revealed that there was an outstanding reduction in the number of serious fractures in the year before and after reconstruction. It was postulated that the improvement in racing time, possibly influenced by reconstructing the geometrical configuration of the racetrack, was connected to the reduction in the number of fractures. Of non biological race- and course-related factors, type of course (dirt or turf), track surface condition, differences between racecourses, and racing distance significantly influence racing time. By using an instrumented shoe, vertical ground reaction forces (VGRFs) on the forelimb during galloping and the relationships between a rough dirt and woodchip track surface and a smooth dirt and woodchip surface were measured. Relating the incidence of racing fractures with track conditions in general showed that track surface has significant effects on the incidence of fracture, with the incidence of fractures increasing as track conditions on dirt worsen and a tendency for the incidence of fractures to decrease as track conditions on turf worsen. It seems probable that track condition in general may affect the incidence of fracture. The incidence of fracture in horses during both racing and training decreased as the years progressed. PMID- 27703406 TI - Autopsy imaging for cardiac tamponade in a Thoroughbred foal. AB - Autopsy imaging (Ai), postmortem imaging before necropsy, is used in human forensic medicine. Ai was performed using computed tomography (CT) for a 1-month old Thoroughbred foal cadaver found in a pasture. CT revealed pericardial effusion, collapse of the aorta, bleeding in the lung lobe, gas in the ventricles and liver parenchyma, and distension of the digestive tract. Rupture in the left auricle was confirmed by necropsy; however, it was not depicted on CT. Therefore, Ai and conventional necropsy are considered to complement each other. The cause of death was determined to be traumatic cardiac tamponade. In conclusion, Ai is an additional option for determining cause of death. PMID- 27703405 TI - Sequence variants of BIEC2-808543 near LCORL are associated with body composition in Thoroughbreds under training. AB - Ligand-dependent nuclear receptor compressor-like (LCORL) encodes a transcription factor, and its polymorphisms are associated with measures of skeletal frame size and adult height in several species. Recently, the single nucleotide polymorphism (SNP) BIEC2-808543 located upstream of LCORL was identified as a genetic diagnostic marker associated with withers height in Thoroughbreds. In this study, 322 Thoroughbreds-in-training were genotyped for BIEC2-808543 to evaluate the association between genotype and body composition traits, including body weight, withers height, the ratio of body weight to withers height, chest circumference, and cannon circumference. Of these, withers height and cannon circumference were significantly associated with LCORL genotypes throughout almost the entire training period in males and females. Animals with a C/T genotype had higher withers height (maximum differences of 1.8 cm and 2.1 cm in males and females, respectively) and cannon circumstance (maximum differences of 0.65 cm and 0.48 cm in males and females, respectively) compared with animals with a T/T genotype. These results suggested that the regulation of LCORL expression influences the skeletal frame size in Thoroughbreds and thus, indirectly affects the body weight. Although LCORL and BIEC2-808543 would be useful for selective breeding in Thoroughbreds, the production of genetically modified animals and gene doping based on genetic information should be prohibited in order to maintain racing integrity. PMID- 27703407 TI - Four cases of equine motor neuron disease in Japan. AB - In this study, fasciculation of the limbs and tongue was observed in four horses kept by a riding club. Neurogenic muscle atrophy was also observed in biopsy of pathological tissues. In addition, in two cases that subjected to autopsy, Bunina like bodies of inclusion in the cell bodies of neurons in the spinal cord ventral horn were confirmed, leading to a diagnosis of equine motor neuron disease (EMND). Serum vitamin E concentrations varied between 0.3 and 0.4ug/ml, which is significantly lower than the levels in normal horses. Although lack of vitamin E is speculated to be a contributory factor for development of EMND, no significant improvement was observed following administration of vitamin E. PMID- 27703408 TI - Reference range of blood biomarkers for oxidative stress in Thoroughbred racehorses (2-5 years old). AB - The oxidant and antioxidant equilibrium is known to play an important role in equine medicine and equine exercise physiology. There are abundant findings in this field; however, not many studies have been conducted for reference ranges of oxidative stress biomarkers in horses. This study was conducted to determine the reference values of reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) using blood samples from 372 (191 males, 181 females) Thoroughbred racehorse aged 2 to 5 (3.43 +/- 1.10 (mean +/- SD)) years old. There were obvious gender differences in oxidative biomarkers, and growth/age-related changes were observed especially in females. Gender and age must be considered when interpreting obtained oxidative stress biomarkers for diagnosis of disease or fitness alterations in Thoroughbred racehorses. PMID- 27703411 TI - Phillip D. Wilson, Jr., MD: A Life Fulfilled. PMID- 27703409 TI - Current Immunotherapies for Sarcoma: Clinical Trials and Rationale. AB - Sarcoma tumors are rare and heterogeneous, yet they possess many characteristics that may facilitate immunotherapeutic responses. Both active strategies including vaccines and passive strategies involving cellular adoptive immunotherapy have been applied clinically. Results of these clinical trials indicate a distinct benefit for select patients. The recent breakthrough of immunologic checkpoint inhibition is being rapidly introduced to a variety of tumor types including sarcoma. It is anticipated that these emerging immunotherapies will exhibit clinical efficacy for a variety of sarcomas. The increasing ability to tailor immunologic therapies to sarcoma patients will undoubtedly generate further enthusiasm and clinical research for this treatment modality. PMID- 27703412 TI - All-Arthroscopic Modified Rotator Interval Slide for Massive Anterosuperior Cuff Tears Using the Subdeltoid Space: Surgical Technique and Early Results. AB - BACKGROUND: Traditional intra-articular arthroscopic repair techniques for massive anterosuperior rotator cuff tears are technically demanding and necessitate sacrifice of the rotator interval to enable visualization. An interval slide allows mobilization through release of the medial aspect of the rotator interval, while leaving the lateral, bridging fibers intact. QUESTIONS/PURPOSES: The purpose of this study was to report a novel, arthroscopic, open-equivalent technique using the subdeltoid space to address these tears along with early clinical results. METHODS: A retrospective review of prospectively collected data identified 11 consecutive arthroscopic massive anterosuperior rotator cuff repairs with a concomitant biceps tenodesis performed by the senior surgeon using a uniform technique. Outcome measures included range of motion, visual analog scale for pain, rotator cuff strength, American Shoulder and Elbow Surgeons (ASES) outcome scale, and Short Form-12 (SF-12). RESULTS: Average length of follow-up was 22.2 months (range 12.5-30.0 months). Visual analog scale (VAS) pain scores, ASES, and SF-12 all demonstrated significant improvement from pre-op to final follow-up from 6.2 to 0.9 (p < 0.05), 27.4 to 82.8 (p < 0.05), and 26.6 to 45.5 (p < 0.05) respectively. Average forward flexion improved from 145 degrees to 160 degrees (p < 0.05). Seven of the nine patients with a positive preoperative belly press had a negative test at final follow-up. Nine of the 10 patients with a positive lift off test demonstrated a negative test on final follow-up. Ninety-one percent reported they were satisfied with their outcome. CONCLUSIONS: The described modified all-arthroscopic subdeltoid approach for anterosuperior cuff repairs enabled an open-equivalent interval slide technique that preserved the bridging lateral fibers of the rotator interval and demonstrated promising early-term clinical results. PMID- 27703410 TI - Fundamental Characteristics of AAA+ Protein Family Structure and Function. AB - Many complex cellular events depend on multiprotein complexes known as molecular machines to efficiently couple the energy derived from adenosine triphosphate hydrolysis to the generation of mechanical force. Members of the AAA+ ATPase superfamily (ATPases Associated with various cellular Activities) are critical components of many molecular machines. AAA+ proteins are defined by conserved modules that precisely position the active site elements of two adjacent subunits to catalyze ATP hydrolysis. In many cases, AAA+ proteins form a ring structure that translocates a polymeric substrate through the central channel using specialized loops that project into the central channel. We discuss the major features of AAA+ protein structure and function with an emphasis on pivotal aspects elucidated with archaeal proteins. PMID- 27703413 TI - The Quality of Open-Access Video-Based Orthopaedic Instructional Content for the Shoulder Physical Exam is Inconsistent. AB - BACKGROUND: The internet has an increasing role in both patient and physician education. While several recent studies critically appraised the quality and accuracy of web-based written information available to patients, no studies have evaluated such parameters for open-access video content designed for provider use. QUESTIONS/PURPOSES: The primary goal of the study was to determine the accuracy of internet-based instructional videos featuring the shoulder physical examination. METHODS: An assessment of quality and accuracy of said video content was performed using the basic shoulder examination as a surrogate for the "best case scenario" due to its widely accepted components that are stable over time. Three search terms ("shoulder," "examination," and "shoulder exam") were entered into the four online video resources most commonly accessed by orthopaedic surgery residents (VuMedi, G9MD, Orthobullets, and YouTube). Videos were captured and independently reviewed by three orthopaedic surgeons. Quality and accuracy were assessed in accordance with previously published standards. RESULTS: Of the 39 video tutorials reviewed, 61% were rated as fair or poor. Specific maneuvers such as the Hawkins test, O'Brien sign, and Neer impingement test were accurately demonstrated in 50, 36, and 27% of videos, respectively. Inter-rater reliability was excellent (mean kappa 0.80, range 0.79-0.81). CONCLUSION: Our results suggest that information presented in open-access video tutorials featuring the physical examination of the shoulder is inconsistent. Trainee exposure to such potentially inaccurate information may have a significant impact on trainee education. PMID- 27703414 TI - Normal Femorotibial Rotational Alignment and Implications for Total Knee Arthroplasty: an MRI Analysis. AB - BACKGROUND: Rotational alignment of prosthetic components in total knee arthroplasty (TKA) is important to successful outcomes. Component malrotation is a known cause of revision and understanding normal rotational alignment may help recreate normal joint kinematics. To date, no large MRI study assessing femorotibial rotational alignment in nonarthritic knees has been undertaken. QUESTIONS/PURPOSES: Is Insall's tibial axis a reliable rotational landmark against common femoral rotational axes in the nonarthritic patient population? METHODS: We reviewed 544 knee MRI scans performed for suspected soft tissue pathology and identified Insall's tibial rotational axis as well as the femoral clinical trans-epicondylar axis (TEAc), femoral surgical trans-epicondylar axis (TEAs), posterior condylar articular axis (PCA), and a modified Eckhoff's cylindrical axis. The perpendiculars of these axes were superimposed on Insall's tibial axis, and the angular differences were measured. RESULTS: Insall's axis was internally rotated to the TEAc by 1.4 degrees , externally rotated to Eckhoff's cylindrical axis by 1.8 degrees , externally rotated to the TEAs by 2.7 degrees , and externally rotated to the PCA by 3.5 degrees . The mean deviation from 0 degrees (optimal alignment for each femoral axis) was significantly greater for the PCA relative to all other femoral axis. CONCLUSION: Insall's axis is a reliable landmark for rotational positioning of the tibial component and may optimize femorotibial kinematics in fixed-bearing TKA. PMID- 27703415 TI - Handheld Navigation Device and Patient-Specific Cutting Guides Result in Similar Coronal Alignment for Primary Total Knee Arthroplasty: a Retrospective Matched Cohort Study. AB - BACKGROUND: Proper alignment of total knee arthroplasty (TKA) is essential for TKA function and may reduce the risk of aseptic failure. Technologies that prevent malalignment may reduce the risk of revision surgery. QUESTIONS/PURPOSES: The purpose of this study was to compare two competing TKA systems that purport improved alignment: patient-specific instrumentation (PSI), and a handheld portable navigation device (NAV). METHODS: After IRB approval, 49 consecutive PSI TKAs (40 patients) were matched based on preoperative characteristics to 49 NAV TKAs (40 patients) performed by a single surgeon. A blinded observer measured alignment on digital radiographs. Operating room records were reviewed for procedure times. Two-tailed paired sample t tests and McNemar's test were used as appropriate. Alpha level was 0.05 for all tests. RESULTS: Preoperative cohort characteristics were not different. Mean postoperative long-leg mechanical alignment was within +/-1 degrees of neutral for both groups, although statistically different (p = 0.026). There were no other significant differences in coronal alignment. PSI exhibited significantly greater posterior tibial slope (4.4 degrees ) compared to NAV (2.7 degrees ) (p = 0.004); PSI resulted in significantly more outliers (>6 degrees ; p = 0.004). Procedure time for unilateral TKAs was lower for PSI (74.4 min) compared to that for NAV (80.6 min; p = 0.023). CONCLUSION: NAV and PSI technologies provided excellent coronal plane alignment. NAV was better for sagittal tibial slope, while PSI procedure times were shorter for unilateral TKA. The impact of these technologies on patient reported outcomes and TKA survivorship is controversial and should be the focus of future research. PMID- 27703416 TI - ACL Damage and Deficiency is Associated with More Severe Preoperative Deformity, Lower Range of Motion at the Time of TKA. AB - BACKGROUND: ACL status varies in the arthritic knee during TKA. QUESTIONS/PURPOSES: The purpose of this study was to examine clinical features and intraoperative findings associated with stages of ACL degeneration. METHODS: Coronal deformity, ROM, intra-articular degenerative patterns, and ligament releases were assessed for 1656 knees during TKA. Common patterns of deformity and severity of degenerative change were assessed as a function of the severity of ACL deficiency. RESULTS: Of the 1656 knees assessed, 27% had a normal ACL, 55% exhibited damage, and 18% exhibited complete absence of the ACL. Increased coronal deformity and lower preoperative ROM was associated with ACL deficiency. Increased chondral and meniscal damage and more extensive osteophyte formation were also found. More extensive ligament releases were required in ACL-deficient knees. CONCLUSIONS: The status of the ACL is predictive of the need for increased surgical deformity correction. A better understanding of ACL status is an important consideration during in choosing TKA as opposed to unicompartmental arthroplasty. The status of the ACL should be considered in planning for implant choice in TKA. PMID- 27703417 TI - Higher Acetabular Anteversion in Direct Anterior Total Hip Arthroplasty: A Retrospective Case-Control Study. AB - BACKGROUND: Surgical approach is known as a risk factor that influences cup malposition while performing total hip arthroplasty (THA). However, no study has been conducted comparing cup positioning between the supine direct anterior (DA) and supine direct lateral (DL) THA approaches. QUESTIONS/PURPOSES: (1) Is there a difference in acetabular cup positioning between supine DA and supine DL THA approaches? (2) Are there differences in complications based on acetabular cup positioning between the two approaches? METHODS: From 2012 to 2014, 186 patients who underwent primary THAs using DA approach were matched with 186 patients using DL approach by body mass index, age, and gender. Cup anteversion and abduction angles were measured from standing anteroposterior pelvis radiographs by two blinded observers. The Lewinnek safe zone was used as the standard for cup positioning. Cup anteversion, abduction angles, and complications were recorded and compared. RESULTS: Cup anteversion was on average 3 degrees higher in the DA approach compared to the DL approach. The abduction angle for the DA approach was equivalent to the DL approach both averaging 46 degrees to 47 degrees . There were more DA hips outside of the safe zone (10%) for anteversion than DL (3%) hips. There were no differences in complications between DA and DL approaches. CONCLUSION: There is a tendency to antevert the acetabular cup when performing THAs using the DA approach, and one must be mindful of this when implanting the acetabular component. PMID- 27703418 TI - Association between Achilles tightness and lower extremity injury in children. AB - BACKGROUND: It is unclear whether isolated gastroc/soleus tightness can increase the risk of lower extremity injury in an otherwise healthy child. QUESTIONS/PURPOSES: (1) Is there a difference in gastroc/soleus tightness, as represented by ankle dorsiflexion with the knee extended, in children presenting with upper versus lower extremity complaints? (2) Is there a difference in gastroc/soleus tightness in children presenting with atraumatic versus traumatic lower extremity complaints? METHODS: We performed a cross-sectional study of 206 consecutive walking age children presenting to a county orthopedic clinic with new upper or lower extremity complaints. Passive ankle dorsiflexion was measured based on the lateral border of the foot versus the anterior lower leg with the knee fully extended and the foot in inversion. RESULTS: Average age was 10.0 +/- 4.5 years. In the 117 patients presenting with upper extremity complaints, ankle dorsiflexion was 15.0 degrees +/- 11.6 degrees . Of the lower extremity patients, 40 presented without trauma, with dorsiflexion of 11.8 degrees +/- 14.5 degrees , while 49 presented with trauma, with dorsiflexion of 6.5 degrees +/- 12.0 degrees . Multiple regression analysis found significantly decreased ankle dorsiflexion with increasing age and in the lower extremity trauma group. Twelve percent of upper extremity patients had 0 degrees or less of dorsiflexion, as compared to 25% of lower extremity nontrauma patients and 41% of lower extremity trauma patients. CONCLUSIONS: Patients presenting with lower extremity trauma had significantly more gastroc/soleus tightness in their well leg than patients presenting with upper extremity complaints. Gastroc/soleus tightness may present a simple target for reducing lower extremity injury rates in children. PMID- 27703419 TI - Spontaneous Fractures of a Modern Modular Uncemented Femoral Stem. AB - BACKGROUND: Femoral stem fracture following total hip arthroplasty is an uncommon event that requires immediate revision surgery. QUESTIONS/PURPOSES: We report on four patients who experienced stem fractures of one design and a review of the US Food and Drug Administration adverse event reports on this design. METHODS: Fracture surfaces of four EMPERIONTM (Smith & Nephew, Memphis, TN) femoral stems were analyzed under optical and scanning electron microscopy. A search of the FDA's Manufacturer and User Facility Device Experience (MAUDE) that reports on all EMPERIONTM adverse events was completed. RESULTS: Fracture surfaces exhibited characteristics consistent with a fatigue fracture mechanism. Sixteen MAUDE reports claimed stem fracture or breakage of EMPERIONTM stems. CONCLUSION: The four cases of EMPERIONTM stem fractures were likely driven by small stem diameter, high offset, and high patient weight. Modular stem-sleeve femoral systems are susceptible to fatigue failure under high stress and should only be used in appropriate patients, whom are not considered obese. PMID- 27703420 TI - Musculoskeletal Involvement in SSc Is Associated with Worse Scores on Short Form 36 and Scleroderma Health Assessment Questionnaire and Lower Tumor Necrosis Factor-alpha Gene Expression in Peripheral Blood Mononuclear Cells. AB - BACKGROUND: Systemic sclerosis (SSc) is characterized by a wide variety of symptoms and disease manifestations including joint pain, gastrointestinal dysfunction, interstitial lung disease, and cardiomyopathy. QUESTIONS/PURPOSES: Using the Scleroderma Health Assessment Questionnaire (SHAQ) and Short Form-36 (SF-36) we explored how patient-reported physical health, mental health, and functional status related to these clinical characteristics and to cytokine levels utilizing the Hospital for Special Surgery Scleroderma Registry. METHODS: In a cross-sectional study of 185 patients meeting the 2013 ACR/EULAR criteria for SSc, we compared disease features and patient-reported outcomes (PROs). Interleukin-6 (IL-6), interleukin-1beta (IL1beta), and tumor necrosis factor alpha (TNFalpha) levels were assessed by luminex and ELISA assays in a subset of 32 patients. The Pearson correlation coefficient, Spearman correlation coefficient, two-sample t test or Wilcoxon rank sum test, ANOVA or Kuskal-Wallis test, and Pearson chi-squared or Fisher's exact test were performed as applicable to detect the association between disease manifestations, PROs, and blood biomarkers. RESULTS: The modified Rodnan skin score (MRSS) was positively correlated with SHAQ scores. Patients who had musculoskeletal involvement scored worse on both the SHAQ and SF-36. Lower levels of TNFalpha expression in PBMCs were also correlated with musculoskeletal involvement. No other significant correlations were found between clinical factors, PROs, and cytokine data. CONCLUSION: Musculoskeletal outcomes are a major determinant of quality of life and function in patients with SSc. These results emphasize the importance of musculoskeletal outcomes in clinical studies of SSc. PMID- 27703421 TI - Treatment of Pre-Collapse Stages of Osteonecrosis of the Femoral Head: a Systematic Review of Randomized Control Trials. AB - BACKGROUND: Treatment for osteonecrosis of the femoral head (ONFH) remains controversial. Current reviews include low-level evidence studies evaluating the treatment of both pre-collapse and collapse stages of the disease. QUESTIONS/PURPOSES: The purpose of the current study is to systematically review the literature evaluating core decompression (CD) with bone marrow mesenchymal cells (BMMCs), CD alone, and bisphosphonate treatment in pre-collapse ONFH by focusing just on randomized clinical trials (RCTs) reporting functional and radiologic outcomes. We aim to determine if the literature provides evidence supporting any single approach. METHODS: Using PubMed and EMBASE databases, we reviewed the clinical evidence of treatments for pre-collapse ONFH following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Twelve RCTs met the inclusion criteria. RESULTS: Results showed that CD with BMMCs has lower risk of femoral head collapse when compared to the CD alone excluding hips lost to follow-up (relative risk (RR) [95% CI]:0.25 [0.11, 0.60]; p = 0.002) and when assumed that hips lost to follow-up experienced collapse (RR [95% CI]: 0.11 [0.03, 0.47]; p = 0.003). Neither CD nor bisphosphonate treatments showed lower risk to femoral head collapse when compared to control treatments (p = 0.46 and 0.31, respectively). CONCLUSION: Current literature shows that there is a lower risk of femoral head collapse in patients with ONFH treated with CD combined with BMMCs when compared to CD alone; however, there is no robust evidence to determine the effect on functional outcomes. More RCTs assessing new combination therapies and using standardized outcome measures are required. PMID- 27703422 TI - Rating a Sports Medicine Surgeon's "Quality" in the Modern Era: an Analysis of Popular Physician Online Rating Websites. AB - BACKGROUND: Consumer-driven healthcare and an increasing emphasis on quality metrics have encouraged patient engagement in the rating of healthcare. As such, online physician rating websites have become mainstream and may play a potential role in future healthcare policy. QUESTIONS/PURPOSES: The purpose of this study was to evaluate online patient ratings for US sports medicine surgeons, determine predictors of positive ratings and analyze for inter-website scoring correlation. METHODS: The American Orthopedic Society for Sports Medicine (AOSSM) member directory was sampled. Surgeon demographic and rating data were searched on three online physicians rating websites: HealthGrades.com (HG), RateMDs.com (RM) and Vitals.com (V). Written rating comments were categorized as relating to the following: surgeon competence, surgeon affability and process of care. Bivariate linear regression, Pearson correlation and multivariable analyses were used to determine factors associated with positive ratings. RESULTS: Two hundred seventy five sports medicine surgeons were included. Two hundred seventy-one (99%) had ratings on at least one of the three websites. Sports surgeons were rated highly across all three websites (mean >4.0/5); however, there was only a low to moderate degree of correlation among websites. On HG, female surgeons and surgeons in academia were more likely to receive higher overall ratings. Across all three websites, increased number of years in practice inversely correlated with ratings; this relationship neared significance for HG and was significant for RM. A surgeon's online presence or geographic location was not associated with higher ratings. In multivariable regression analysis for ratings on HG, female sex was the only significant predictor of higher ratings. Two thousand three hundred forty-one written comments were analyzed: perceived surgeon competence and communication influenced the direction of ratings for the top and bottom tier surgeons. CONCLUSION: There was a low degree of correlation among online websites for surgeon ratings. Female surgeons and those with fewer years in practice appear to have higher ratings on these websites; comment content analysis suggests that high and low ratings are influenced by perceived surgeon competence and affability.

AB - The treatment of displaced proximal humerus fractures is challenging and complex, as its success is predicated on multiple factors. While it is clear that a majority of proximal humerus fractures may be treated nonoperatively, it is less clear which patients benefit from surgical management. The PROFHER trial, a randomized controlled study, used patient-reported outcomes to compare surgical to nonsurgical management of displaced proximal humerus fractures. The purpose of this review is to highlight the strengths and weaknesses of the PROFHER trial and to assess the validity of its conclusion in the context of existing literature. The authors found no difference in the Oxford Shoulder Score (OSS) between the surgical and nonsurgical groups. Additionally, no difference was found between groups in any of the secondary outcomes, which included the Short-Form 12 (SF-12) health survey, surgical and fracture-related complications, additional surgery or therapy, inpatient medical complications, and mortality. They concluded that the recent increase in surgical management of proximal humerus fractures is perhaps unwarranted. While the randomization was successful and the pragmatic design may enable greater generalizability, this study possesses numerous flaws inherent in such an ambitious endeavor, including an inability to identify specific factors which explain the lack of superiority of surgical management. Despite its weaknesses, this study is a valuable datapoint which encourages surgeons to reexamine their surgical indications for this injury.

AB - Kukkonen et al.'s "Treatment of Nontraumatic Rotator Cuff Tears: A Randomized Controlled Trial with Two Years of Clinical and Imaging Follow-up" compared the efficacy of physical therapy, acromioplasty, and rotator cuff repair for the treatment of degenerative supraspinatus tendon tears in patients aged over 55. This review examines the authors' findings and their implications on clinical practice. Kukkonen et al. reported no significant difference in clinical outcome among patients treated operatively versus non-operatively for degenerative rotator cuff tears. The authors concluded that non-operative treatment is an appropriate option for patients aged 55 or older. Rotator cuff treatment outcomes are closely linked to patient age, and while this level I study found no evidence of a benefit of surgical treatment, the age range in the studied demographic was perhaps too wide to draw generalizable conclusions. Furthermore, 2-year follow-up may be inadequate to fully demonstrate the differences in outcomes between these treatment options.

PMID- 27703428 TI - Solitary Langerhans cell histiocytosis of the hard palate: a diagnostic pitfall. AB - Langerhans cell histiocytosis (LCH) is a relatively rare and unique disease characterized by an abnormal proliferation of immature dendritic cells. It is predominantly seen in children with adults showing less than ten times the incidence compared to childhood. The clinical presentation and organ involvement is highly variable. Oral manifestations generally consist of mucosal ulceration associated with lesions of the underlying bone. Lesions limited to the oral mucosa are rare. We present a case of a 45-year-old male who presented with an ulcer on the hard palate showing histopathologic features of LCH. The present case is a reminder of the possibility of occurrence of this unusual entity in the oral cavity. Appropriate use of immunohistochemistry is advocated to avoid diagnostic pitfalls. PMID- 27703429 TI - Amygdalar Auditory Neurons Contribute to Self-Other Distinction during Ultrasonic Social Vocalization in Rats. AB - Although, clinical studies reported hyperactivation of the auditory system and amygdala in patients with auditory hallucinations (hearing others' but not one's own voice, independent of any external stimulus), neural mechanisms of self/other attribution is not well understood. We recorded neuronal responses in the dorsal amygdala including the lateral amygdaloid nucleus to ultrasonic vocalization (USVs) emitted by subjects and conspecifics during free social interaction in 16 adult male rats. The animals emitting the USVs were identified by EMG recordings. One-quarter of the amygdalar neurons (15/60) responded to 50 kHz calls by the subject and/or conspecifics. Among the responsive neurons, most neurons (Type Other neurons; 73%, 11/15) responded only to calls by conspecifics but not subjects. Two Type-Self neurons (13%, 2/15) responded to calls by the subject but not those by conspecifics, although their response selectivity to subjects vs. conspecifics was lower than that of Type-Other neurons. The remaining two neurons (13%) responded to calls by both the subject and conspecifics. Furthermore, population coding of the amygdalar neurons represented distinction of subject vs. conspecific calls. The present results provide the first neurophysiological evidence that the amygdala discriminately represents affective social calls by subject and conspecifics. These findings suggest that the amygdala is an important brain region for self/other attribution. Furthermore, pathological activation of the amygdala, where Type-Other neurons predominate, could induce external misattribution of percepts of vocalization. PMID- 27703430 TI - Early Impairment of Synaptic and Intrinsic Excitability in Mice Expressing ALS/Dementia-Linked Mutant UBQLN2. AB - Frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) are believed to represent the different outcomes of a common pathogenic mechanism. However, while researchers have intensely studied the involvement of motor neurons in the ALS/FTD syndrome, very little is known about the function of hippocampal neurons, although this area is critical for memory and other cognitive functions. We investigated the electrophysiological properties of CA1 pyramidal cells in slices from 1 month-old UBQLN2P497H mice, a recently generated model of ALS/FTD that shows heavy depositions of ubiquilin2-positive aggregates in this brain region. We found that, compared to wild-type mice, cells from UBQLN2P497H mice were hypo-excitable. The amplitude of the glutamatergic currents elicited by afferent fiber stimulation was reduced by ~50%, but no change was detected in paired-pulse plasticity. The maximum firing frequency in response to depolarizing current injection was reduced by ~30%; the fast afterhyperpolarization in response to a range of depolarizations was reduced by almost 10 mV; the maximum slow afterhyperpolarization (sAHP) was also significantly decreased, likely in consequence of the decreased number of spikes. Finally, the action potential (AP) upstroke was blunted and the threshold depolarized compared to controls. Thus, synaptic and intrinsic excitability are both impaired in CA1 pyramidal cells of UBQLN2P497H mice, likely constituting a cellular mechanism for the cognitive impairments. Because these alterations are detectable before the establishment of overt pathology, we hypothesize that they may affect the further course of the disease.

AB - Cistanches Herba (family Orobanchaceae), commonly known as "desert ginseng" or Rou Cong Rong, is a global genus and commonly used for its neuroprotective, immunomodulatory, anti-oxidative, kidney impotence, laxative, anti-inflammatory, hepatoprotective, anti-bacterial, anti-viral, and anti-tumor effects in traditional herbal formulations in North Africa, Arabic, and Asian countries. The major bioactive compound present in this plant is phenylethanoid glycosides. In recent years, there has been great important in scientific investigation of the neuropharmacological effects of the bioactive compounds. The in vitro and in vivo studies suggests these compounds demonstrate neuropharmacological activities against a wide range of complex nervous system diseases which occurs through different mechanisms include improving immunity function and kidney aging, anti lipid peroxidation, scavenging free radical, inducing the activation of caspase-3 and caspase-8. This review aims to summaries the various neuropharmacological effects and mechanisms of Cistanches Herba extracts and related compounds, including its efficacy as a cure for Alzheimer's disease and Parkinson's disease with reference to the published literature. Which provides guidance for further research on the clinical application of Cistanches Herba.

AB - The recent rise in the use of linezolid to treat a variety of resistant pathogens has uncovered many side effects. Some patients develop lactic acidosis, myelosuppression, optic or peripheral neuropathies, and myopathies. We evaluated an elderly patient who presented to the Emergency Room with linezolid toxicity and a novel neurologic complication characterized by bilateral globi pallidi necrosis. Mitochondrial ribosome inhibition was described to be the predisposing factor. The patient belongs to the mitochondrial J1 haplotype known to be associated with side effects of the drug. We recommend based on the molecular profile of the illness pretreatment considerations and complication management.

PMID- 27703435 TI - Ecological Momentary Assessment and Smartphone Application Intervention in Adolescents with Substance Use and Comorbid Severe Psychiatric Disorders: Study Protocol. AB - CONTEXT: Substance use disorders (SUDs) are highly prevalent among inpatient adolescents with psychiatric disorders. In this population, substance use and other psychiatric outcomes can reinforce one another. Despite the need for integrated interventions in youths with dual diagnoses, few specific instruments are available. App-based technologies have shown promising results to help reduce substance use in adolescents, but their applicability in youths with associated severe psychiatric disorders is poorly documented. We aim to evaluate the feasibility of an ecological momentary assessment (EMA) intervention for all substance users, and of a smartphone application for cannabis users (Stop Cannabis), for outpatient treatment after hospital discharge. METHODS AND ANALYSIS: All inpatient adolescents with psychiatric disorders hospitalized between 2016 and 2018 in a university hospital will be systematically screened for SUD and, if positive, will be assessed by an independent specialist addiction team. Participants with confirmed SUDs will be invited and helped to download an EMA app and, if required, the Stop-Cannabis app, the week preceding hospital discharge. Information about the acceptability and use of both apps and the validity of EMA data in comparison to clinical assessments will be assessed after 6 months and 1 year. DISCUSSION: This research has been designed to raise specific issues for consideration regarding the sequence between substance use, contextual factors, and other psychiatric symptoms among adolescents with comorbid severe psychiatric disorders. A better understanding of the mechanisms involved will inform the development of integrated treatment for dual disorders at that age. ETHICS AND DISSEMINATION: The study has already been approved and granted. Dissemination will include presentations at international congresses as well as publications in peer-reviewed journals.

AB - The current study explored the interaction of verbal ability and presentation order on readers' attitude formation when presented with two-sided arguments. Participants read arguments for and against compulsory voting and genetic engineering, and attitudes were assessed before and after reading the passages. Participants' verbal ability was measured, combining vocabulary knowledge and reading comprehension skill. Results suggested that low verbal-ability participants were more persuaded by the most recent set of arguments whereas high verbal-ability participants formed attitudes independent of presentation order. Contrary to previous literature, individual differences in the personality trait need for cognition did not interact with presentation order. The results suggest that verbal ability is an important moderator of the effect of presentation order when formulating opinions from complex prose. PMID- 27703434 TI - A Pilot Study of Mindfulness-Based Exposure Therapy in OEF/OIF Combat Veterans with PTSD: Altered Medial Frontal Cortex and Amygdala Responses in Social Emotional Processing. AB - Combat-related posttraumatic stress disorder (PTSD) is common among returning veterans, and is a serious and debilitating disorder. While highly effective treatments involving trauma exposure exist, difficulties with engagement and early drop may lead to sub-optimal outcomes. Mindfulness training may provide a method for increasing emotional regulation skills that may improve engagement in trauma-focused therapy. Here, we examine potential neural correlates of mindfulness training and in vivo exposure (non-trauma focused) using a novel group therapy [mindfulness-based exposure therapy (MBET)] in Afghanistan (OEF) or Iraq (OIF) combat veterans with PTSD. OEF/OIF combat veterans with PTSD (N = 23) were treated with MBET (N = 14) or a comparison group therapy [Present-centered group therapy (PCGT), N = 9]. PTSD symptoms were assessed at pre- and post therapy with Clinician Administered PTSD scale. Functional neuroimaging (3-T fMRI) before and after therapy examined responses to emotional faces (angry, fearful, and neutral faces). Patients treated with MBET had reduced PTSD symptoms (effect size d = 0.92) but effect was not significantly different from PCGT (d = 0.43). Improvement in PTSD symptoms from pre- to post-treatment in both treatment groups was correlated with increased activity in rostral anterior cingulate cortex, dorsal medial prefrontal cortex (mPFC), and left amygdala. The MBET group showed greater increases in amygdala and fusiform gyrus responses to Angry faces, as well as increased response in left mPFC to Fearful faces. These preliminary findings provide intriguing evidence that MBET group therapy for PTSD may lead to changes in neural processing of social-emotional threat related to symptom reduction.

AB - In the developmental literature, the idea has been proposed that young children do not understand the specificity of non-literal communicative acts. In this article, I focus on young children's ability to produce and understand different forms of humor. I explore the acquisition of the communicative contexts that enable children to engage in humorous interactions before they possess the capacity to analyze them in the terms afforded by a full-fledged theory of mind. I suggest that different forms of humor share several basic features and that we can construct a continuum from simple to sophisticated forms. In particular, I focus on teasing, a form of humor already present in preverbal infants that is also considered a typical feature of irony. I argue that all forms of humor can be regarded as a type of interaction that I propose to call "playing with expectations." PMID- 27703439 TI - The Role of Intuition in the Generation and Evaluation Stages of Creativity. AB - Both intuition and creativity are associated with knowledge creation, yet a clear link between them has not been adequately established. First, the available empirical evidence for an underlying relationship between intuition and creativity is sparse in nature. Further, this evidence is arguable as the concepts are diversely operationalized and the measures adopted are often not validated sufficiently. Combined, these issues make the findings from various studies examining the link between intuition and creativity difficult to replicate. Nevertheless, the role of intuition in creativity should not be neglected as it is often reported to be a core component of the idea generation process, which in conjunction with idea evaluation are crucial phases of creative cognition. We review the prior research findings in respect of idea generation and idea evaluation from the view that intuition can be construed as the gradual accumulation of cues to coherence. Thus, we summarize the literature on what role intuitive processes play in the main stages of the creative problem-solving process and outline a conceptual framework of the interaction between intuition and creativity. Finally, we discuss the main challenges of measuring intuition as well as possible directions for future research. PMID- 27703440 TI - Anodal Stimulation of the Left DLPFC Increases IGT Scores and Decreases Delay Discounting Rate in Healthy Males. AB - Previous correlational imaging studies have implicated the dorsolateral prefrontal cortex (DLPFC) in decision making. Using High-Definition Transcranial Direct Current Stimulation (HD-tDCS), the present study directly investigated the causal role of the DLPFC in performing the Iowa Gambling Task (IGT) and the Inter Temporal Choice (ITC) task. Three experiments were conducted: Experiment 1 (N = 41) to study the left DLPFC, Experiment 2 (N = 49) to study the right DLPFC, and Experiment 3 (N = 20, a subset of those in Experiment 1) to switch the experimental and control conditions. All participants were healthy male college students. For Experiments 1 and 2, participants were randomly assigned to either the HD-tDCS or the sham stimulation condition. For Experiment 3, participants were assigned to the condition they were not in during Experiment 1. Results showed that HD-tDCS over the left DLPFC increased IGT score, decreased the recency parameter in IGT, and lowered delay discounting rate (k) in the ITC task. We discussed the potential roles of impulse control and time perception in mediating the effect of tDCS stimulation of left DLPFC on decision making. Our results have clinical implications for the treatment of disorders involving poor decision-making, such as addictions. PMID- 27703441 TI - Rational Emotive Behavior Therapy (REBT), Irrational and Rational Beliefs, and the Mental Health of Athletes. AB - In this article Rational Emotive Behavior Therapy (REBT) is proposed as a potentially important framework for the understanding and promotion of mental health in athletes. Cognitive-behavioral approaches predominate in the provision of sport psychology, and often form the backbone of psychological skills training for performance enhancement and maintenance. But far from being solely performance-focused, the cognitive-behavioral approach to sport psychology can restore, promote, and maintain mental health. This review article presents REBT (Ellis, 1957), the original cognitive behavioral therapy, as a valuable approach to addressing mental health issues in sport. REBT holds that it is not events that directly cause emotions and behaviors. Rather, it is one's beliefs about the events that lead to emotional and behavioral reactivity. Further, REBT distinguishes between rational and irrational beliefs, and suggests that in response to failure, maltreatment, and misfortune, people can react with either healthy or unhealthy emotional and behavioral responses. The extant research indicates that irrational beliefs lead to unhealthy negative emotions, a range of pathological conditions, and a host of maladaptive behaviors that undermine mental health. Therefore, REBT proposes a process for the reduction of irrational beliefs and the promotion of rational beliefs. The use of REBT in sport is seldom reported in literature, but research is growing. This review article proposes three important areas of investigation that will aid the understanding of irrational beliefs and the application of REBT within sport. These areas are: (1) the influence of irrational beliefs and REBT on the mental health of athletes, (2) the influence of irrational beliefs and REBT on athletic performance, (3) the origins and development of irrational beliefs in athletes. Each area is discussed in turn, offering a critical and progressive review of the literature as well as highlighting research deficits, and recommendations to address each of the three areas of investigation.

AB - INTRODUCTION: Visual impairment, specifically eye movement disorders and vestibular dysfunction may have a negative influence on the functional recovery in post-stroke patients. This type of sensory dysfunction may further be associated with poor functional outcome in patients' post-stroke. METHODS: In phase 1, a cross-sectional survey (n = 100) will be conducted to determine the prevalence of eye movement disorders and vestibular dysfunction in patients who sustained a stroke. A cross-sectional clinical trial (n = 60) will be conducted during phase 2 of the study to determine the effect of the combination of vestibular rehabilitation therapy (VRT) and visual scanning exercises (VSE) (experimental group) integrated with task-specific activities compared with the effect of task-specific activities as an intervention (control group) on patients who present with eye movement impairment and central vestibular dysfunction post stroke. An audiologist will assess (a) visual acuity (static and dynamic), (b) nystagmus, (c) saccadic eye movements, (d) smooth pursuit eye movements, (e) vestibulo-ocular reflex, and (f) saccular, utricular, and vestibular nerve function. An independent physiotherapist will assess (1) cognitive function, (2) residual oculomotor visual performance, (3) visual-perceptual system, (4) functional balance, (5) gait, (6) functional ability, (7) presence of anxiety and/or depression, and (8) level of participation in physical activity. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the Ethics Committee of the Faculty of Health Sciences at the University of Pretoria (UP) (374/2015). The study will be submitted as fulfillment for the PhD degree at UP. Dissemination will include submission to peer-reviewed professional journals and presentation at congresses. Training of rehabilitation team members on the integration of VSE and VRT into task-specific activities in rehabilitation will be done if the outcome of the experimental group's functional performance is clinically and statistically significantly better than the control group on the Barthel Index.

PMID- 27703444 TI - Prevalence of Brain MRI Markers of Hemorrhagic Risk in Patients with Stroke and Atrial Fibrillation. AB - BACKGROUND AND PURPOSE: Cerebral microbleeds (CMBs), cortical superficial siderosis, white matter lesions (WML), and cerebral atrophy may signify greater bleeding risk particularly in patients in whom anticoagulation is to be considered. We investigated their prevalence and associations with stroke type in patients with stroke and atrial fibrillation (AF). MATERIALS AND METHODS: Cross sectional sample, Monash Medical Centre (Melbourne, Australia) between 2010 and 2013, with brain MRI. MRI abnormalities were rated using standardized methods. Logistic regression was used to study associations adjusting for age and sex. RESULTS: There were 170 patients, mean age 78 years (SD 9.8), 154 (90.6%) with ischemic stroke. Prevalence of MRI markers were any microbleed 49%, multiple (>=2) microbleeds 30%, confluent WMLs 18.8%, siderosis 8.9%, severe cerebral atrophy 37.7%. Combinations of the severe manifestations of these markers were much less prevalent (2.9-12.4%). Compared with ischemic stroke, those with hemorrhagic stroke were more likely to have >=10 microbleeds (OR 5.50 95% CI 1.46 20.77, p = 0.012) and siderosis (OR 6.24, 95% CI 1.74-22.40, p = 0.005). Siderosis was associated with multiple microbleeds (OR 8.14, 95% CI 2.38-27.86, p = 0.001). Patients admitted with hemorrhagic stroke and multiple microbleeds were more frequently anticoagulated prior to stroke (6/7, 85.7%) than in those with single (1/2, 50%) or no microbleeds (4/7, 57%). CONCLUSION: Multiple CMBs, severe WML, and severe cerebral atrophy were common individually in hospitalized patients with stroke and AF, but less so in combination. A higher burden of CMBs may be associated with intracerebral hemorrhage in stroke patients with AF. PMID- 27703445 TI - Asking New Questions with Old Data: The Centralized Open-Access Rehabilitation Database for Stroke. AB - BACKGROUND: This paper introduces a tool for streamlining data integration in rehabilitation science, the Centralized Open-Access Rehabilitation database for Stroke (SCOAR), which allows researchers to quickly visualize relationships among variables, efficiently share data, generate hypotheses, and enhance clinical trial design. METHODS: Bibliographic databases were searched according to inclusion criteria leaving 2,892 titles that were further screened to 514 manuscripts to be screened by full text, leaving 215 randomized controlled trials (RCTs) in the database (489 independent groups representing 12,847 patients). Demographic, methodological, and statistical data were extracted by independent coders and entered into SCOAR. RESULTS: Trial data came from 114 locations in 27 different countries and represented patients with a wide range of ages, 62 year [41; 85] [shown as median (range)] and at various stages of recovery following their stroke, 141 days [1; 3372]. There was considerable variation in the dose of therapy that patients received, 20 h [0; 221], over interventions of different durations, 28 days [10; 365]. There was also a lack of common data elements (CDEs) across trials, but this lack of CDEs was most pronounced for baseline assessments of patient impairment and severity of stroke. CONCLUSION: Data integration across hundreds of RCTs allows clinicians and researchers to quickly visualize data from the history of the field and lays the foundation for making SCOAR a living database to which researchers can upload new data as trial results are published. SCOAR is a useful tool for clinicians and researchers that will facilitate data visualization, data sharing, the finding of relevant past studies, and the design of clinical trials by enabling more accurate and comprehensive power analyses. Furthermore, these data speak to the need for CDEs specific to stroke rehabilitation in randomized controlled trials. PROSPERO 2014: CRD42014009010. PMID- 27703446 TI - A Novel Germline Mutation of KEAP1 (R483H) Associated with a Non-Toxic Multinodular Goiter. AB - BACKGROUND: A germline mutation of KEAP1 gene was reported as a novel genetic abnormality associated with familial multinodular goiter. That report was limited, and the pathogenic features were not well established. PATIENT FINDINGS: We report a 47-year-old Japanese woman who presented with hyperthyroidism and a large multinodular goiter. The family history was notable for a paternal history of goiter. Graves' disease was diagnosed based on positive TRAb, but scintiscan imaging showed that the patient's radioiodine uptake was restricted in the non nodular areas, indicating largely cold nodules. A total thyroidectomy was performed. The resected thyroid tissue weighed 209 g, and subsequent pathological findings were benign. The patient had a germline heterozygous KEAP1 mutation, c. 1448 G > A, resulting in an amino acid substitution (p.R483H). A next-generation sequencing analysis covering all known genes associated with multinodular goiter showed no additional germline mutation. The nuclear accumulation of NRF2, a protein associated with KEAP1, was shown at much higher rates in the patient's nodules compared with nodules obtained from four unrelated patients with multinodular goiters. CONCLUSION: A novel germline mutation (R483H) of KEAP1 gene was associated with the development of a non-toxic multinodular goiter. PMID- 27703447 TI - Autophagy Is Associated with Pathogenesis of Haemophilus parasuis. AB - Haemophilus parasuis (H. parasuis) is a common commensal Gram-negative extracellular bacterium in the upper respiratory tract of swine, which can cause Glasser's disease in stress conditions. Research on the pathogenicity of H. parasuis has mainly focused on immune evasion and bacterial virulence factors, while few studies have examined the interactions of H. parasuis and its host. Autophagy is associated with the replication and proliferation of many pathogenic bacteria, but whether it plays a role during infection by H. parasuis is unknown. In this study, an adenovirus construct expressing GFP, RFP, and LC3 was used to infect H. parasuis. Western blotting, laser confocal microscopy, and electron microscopy showed that Hps5 infection induced obvious autophagy in PK-15 cells. In cells infected with strains of H. parasuis differing in invasiveness, the levels of autophagy were positively correlated with the presence of alive bacteria in PK-15 cells. In addition, autophagy inhibited the invasion of Hps5 in PK-15 cells. Autophagy related genes Beclin, Atg5 and Atg7 were silenced with RNA interference, the results showed that autophagy induced by H. parasuis infection is a classical pathway. Our observations demonstrate that H. parasuis can induce autophagy and that the levels of autophagy are associated with the presence of alive bacteria in cells, which opened novel avenues to further our understanding of H. parasuis-host interplay and pathogenesis. PMID- 27703448 TI - Oxygen Tension and Riboflavin Gradients Cooperatively Regulate the Migration of Shewanella oneidensis MR-1 Revealed by a Hydrogel-Based Microfluidic Device. AB - Shewanella oneidensis is a model bacterial strain for studies of bioelectrochemical systems (BESs). It has two extracellular electron transfer pathways: (1) shuttling electrons via an excreted mediator riboflavin; and (2) direct contact between the c-type cytochromes at the cell membrane and the electrode. Despite the extensive use of S. oneidensis in BESs such as microbial fuel cells and biosensors, many basic microbiology questions about S. oneidensis in the context of BES remain unanswered. Here, we present studies of motility and chemotaxis of S. oneidensis under well controlled concentration gradients of two electron acceptors, oxygen and oxidized form of riboflavin (flavin+), using a newly developed microfluidic platform. Experimental results demonstrate that either oxygen or flavin+ is a chemoattractant to S. oneidensis. The chemotactic tendency of S. oneidensis in a flavin+ concentration gradient is significantly enhanced in an anaerobic in contrast to an aerobic condition. Furthermore, either a low oxygen tension or a high flavin+ concentration considerably enhances the speed of S. oneidensis. This work presents a robust microfluidic platform for generating oxygen and/or flavin+ gradients in an aqueous environment, and demonstrates that two important electron acceptors, oxygen and oxidized riboflavin, cooperatively regulate S. oneidensis migration patterns. The microfluidic tools presented as well as the knowledge gained in this work can be used to guide the future design of BESs for efficient electron production. PMID- 27703449 TI - Exploratory Investigation of Bacteroides fragilis Transcriptional Response during In vitro Exposure to Subinhibitory Concentration of Metronidazole. AB - Bacteroides fragilis, member from commensal gut microbiota, is an important pathogen associated to endogenous infections and metronidazole remains a valuable antibiotic for the treatment of these infections, although bacterial resistance is widely reported. Considering the need of a better understanding on the global mechanisms by which B. fragilis survive upon metronidazole exposure, we performed a RNA-seq transcriptomic approach with validation of gene expression results by qPCR. Bacteria strains were selected after in vitro subcultures with subinhibitory concentration (SIC) of the drug. From a wild type B. fragilis ATCC 43859 four derivative strains were selected: first and fourth subcultures under metronidazole exposure and first and fourth subcultures after drug removal. According to global gene expression analysis, 2,146 protein coding genes were identified, of which a total of 1,618 (77%) were assigned to a Gene Ontology term (GO), indicating that most known cellular functions were taken. Among these 2,146 protein coding genes, 377 were shared among all strains, suggesting that they are critical for B. fragilis survival. In order to identify distinct expression patterns, we also performed a K-means clustering analysis set to 15 groups. This analysis allowed us to detect the major activated or repressed genes encoding for enzymes which act in several metabolic pathways involved in metronidazole response such as drug activation, defense mechanisms against superoxide ions, high expression level of multidrug efflux pumps, and DNA repair. The strains collected after metronidazole removal were functionally more similar to those cultured under drug pressure, reinforcing that drug-exposure lead to drastic persistent changes in the B. fragilis gene expression patterns. These results may help to elucidate B. fragilis response during metronidazole exposure, mainly at SIC, contributing with information about bacterial survival strategies under stress conditions in their environment.

The main aims of this study were, to characterize and identify the pathogenic strain using biochemical and molecular methods to demonstrate its pathogenic activity on scallop larvae, to characterize its pathogenic properties and to describe the chronology of this pathology. The pathogenic strain was identified as Vibrio tubiashii based on its phenotypic properties and the sequence analysis of its 16S rRNA and housekeeping genes (ftsZ, gapA, gyrB, mreB, pyrH, recA, rpoA and topA). When triplicate cultures of healthy 10-day-old scallop larvae were challenged with 1 * 105 colony forming units (CFU) mL-1 of the VPAP30 strain, percentages of larval survival of 78.87 +/ 3.33%, 34.32 +/- 4.94%, and 0% were observed at 12, 24, and 36 h, respectively; whereas uninfected larval cultures showed survival rates of 97.4 +/- 1.24% after of 48 h. Clinical symptoms exhibited by the scallop larvae infected with the VPAP30 strain include the accumulation of bacteria around the scallop larvae, velum disruption and necrosis of digestive gland. The 50% lethal dose (LD50) of VPAP30 strain at 24 and 48 h was 1.3 * 104 and 1.2 * 103 CFU mL-1, respectively. The invasive pathogenic activity of the VPAP30 strain was investigated with staining of the bacterial pathogen with 5-DTAF and analyzing bacterial invasion using epifluorescence, and a complete bacterial dissemination inside the larvae at 24 h post-infection was observed. When scallop larvae were inoculated with cell-free extracellular products (ECPs) of VPAP30, the larval survival rate was 59.5 +/- 1.66%, significantly (P < 0.001) lower than the control group (97.4 +/- 1.20%) whereas larvae treated with heat-treated ECPs exhibited a survival rate of 61.6 +/- 1.84% after 48 h of exposure. This is the first report of the isolation of V. tubiashii from the diseased larvae of the scallop A. purpuratus, occurring in a commercial culture in Chile, and it was demonstrated that the VPAP30 strain exhibits high pathogenic activity on scallop larvae, mediated both by bacterial invasion and the production of toxigenic heat-stable compounds. PMID- 27703451 TI - Comparative Transcriptomic Analysis Reveals Novel Insights into the Adaptive Response of Skeletonema costatum to Changing Ambient Phosphorus. AB - Phosphorus (P) is a limiting macronutrient for diatom growth and productivity in the ocean. Much effort has been devoted to the physiological response of marine diatoms to ambient P change, however, the whole-genome molecular mechanisms are poorly understood. Here, we utilized RNA-Seq to compare the global gene expression patterns of a marine diatom Skeletonema costatum grown in inorganic P replete, P-deficient, and inorganic- and organic-P resupplied conditions. In total 34,942 unique genes were assembled and 20.8% of them altered significantly in abundance under different P conditions. Genes encoding key enzymes/proteins involved in P utilization, nucleotide metabolism, photosynthesis, glycolysis, and cell cycle regulation were significantly up-regulated in P-deficient cells. Genes participating in circadian rhythm regulation, such as circadian clock associated 1, were also up-regulated in P-deficient cells. The response of S. costatum to ambient P deficiency shows several similarities to the well-described responses of other marine diatom species, but also has its unique features. S. costatum has evolved the ability to re-program its circadian clock and intracellular biological processes in response to ambient P deficiency. This study provides new insights into the adaptive mechanisms to ambient P deficiency in marine diatoms. PMID- 27703452 TI - Anti-rheumatoid Activity of Secondary Metabolites Produced by Endophytic Chaetomium globosum. AB - The aim of the present study was to investigate the anti-rheumatoid activity of secondary metabolites produced by endophytic mycobiota in Egypt. A total of 27 endophytic fungi were isolated from 10 dominant medicinal plant host species in Wadi Tala, Saint Katherine Protectorate, arid Sinai, Egypt. Of those taxa, seven isolates of Chaetomium globosum (CG1-CG7), being the most frequent taxon, were recovered from seven different host plants and screened for production of active anti-inflammatory metabolites. Isolates were cultivated on half - strength potato dextrose broth for 21 days at 28 degrees C on a rotatory shaker at 180 rpm, and extracted in ethyl acetate and methanol, respectively. The probable inhibitory effects of both extracts against an adjuvant induced arthritis (AIA) rat model were examined and compared with the effects of methotrexate (MTX) as a standard disease-modifying anti-rheumatoid drug. Disease activity and mobility scoring of AIA, histopathology and transmission electron microscopy (TEM) were used to evaluate probable inhibitory roles. A significant reduction (P < 0.05) in the severity of arthritis was observed in both the methanolic extract of CG6 (MCG6) and MTX treatment groups 6 days after treatment commenced. The average arthritis score of the MCG6 treatment group was (10.7 +/- 0.82) compared to (13.8 +/- 0.98) in the positive control group. The mobility score of the MCG6 treatment group (1.50 +/- 0.55) was significantly lower than that of the positive control group (3.33 +/- 0.82). In contrast, the ethyl acetate extract of CG6 (EACG6) treatment group showed no improvements in arthritis and mobility scores in AIA model rats. Histopathology and TEM findings confirmed the observation. Isolate CG6 was subjected to sequencing for confirmation of phenotypic identification. The internal transcribed spacer (ITS) 1-5.8 s - ITS2 rDNA sequences obtained were compared with those deposited in the GenBank Database and registered with accession number KC811080 in the NCBI Database. The present study revealed that the methanol extract of endophytic fungus C. globosum (KC811080) recovered from maidenhair fern has an inhibitory effect on inflammation, histopathology and morphological features of rheumatoid arthritis in an AIA rat model. PMID- 27703453 TI - Evaluation of the Microbial Diversity in Amyotrophic Lateral Sclerosis Using High Throughput Sequencing. AB - More and more evidences indicate that diseases of the central nervous system have been seriously affected by fecal microbes. However, little work is done to explore interaction between amyotrophic lateral sclerosis (ALS) and fecal microbes. In the present study, high-throughput sequencing method was used to compare the intestinal microbial diversity of healthy people and ALS patients. The principal coordinate analysis, Venn and unweighted pair-group method using arithmetic averages (UPGMA) showed an obvious microbial changes between healthy people (group H) and ALS patients (group A), and the average ratios of Bacteroides, Faecalibacterium, Anaerostipes, Prevotella, Escherichia, and Lachnospira at genus level between ALS patients and healthy people were 0.78, 2.18, 3.41, 0.35, 0.79, and 13.07. Furthermore, the decreased Firmicutes/Bacteroidetes ratio at phylum level using LEfSE (LDA > 4.0), together with the significant increased genus Dorea (harmful microorganisms) and significant reduced genus Oscillibacter, Anaerostipes, Lachnospiraceae (beneficial microorganisms) in ALS patients, indicated that the imbalance in intestinal microflora constitution had a strong association with the pathogenesis of ALS. PMID- 27703454 TI - Exome Sequencing Reveals Primary Immunodeficiencies in Children with Community Acquired Pseudomonas aeruginosa Sepsis. AB - One out of three pediatric sepsis deaths in high income countries occur in previously healthy children. Primary immunodeficiencies (PIDs) have been postulated to underlie fulminant sepsis, but this concept remains to be confirmed in clinical practice. Pseudomonas aeruginosa (P. aeruginosa) is a common bacterium mostly associated with health care-related infections in immunocompromised individuals. However, in rare cases, it can cause sepsis in previously healthy children. We used exome sequencing and bioinformatic analysis to systematically search for genetic factors underpinning severe P. aeruginosa infection in the pediatric population. We collected blood samples from 11 previously healthy children, with no family history of immunodeficiency, who presented with severe sepsis due to community-acquired P. aeruginosa bacteremia. Genomic DNA was extracted from blood or tissue samples obtained intravitam or postmortem. We obtained high-coverage exome sequencing data and searched for rare loss-of-function variants. After rigorous filtrations, 12 potentially causal variants were identified. Two out of eight (25%) fatal cases were found to carry novel pathogenic variants in PID genes, including BTK and DNMT3B. This study demonstrates that exome sequencing allows to identify rare, deleterious human genetic variants responsible for fulminant sepsis in apparently healthy children. Diagnosing PIDs in such patients is of high relevance to survivors and affected families. We propose that unusually severe and fatal sepsis cases in previously healthy children should be considered for exome/genome sequencing to search for underlying PIDs. PMID- 27703455 TI - Modulation of Phenotype and Function of Human CD4+CD25+ T Regulatory Lymphocytes Mediated by cAMP-Elevating Agents. AB - We have shown that cholera toxin (CT) and other cyclic AMP (cAMP)-elevating agents induce upregulation of the inhibitory molecule CTLA-4 in human resting CD4+ T lymphocytes, which following the treatment acquired suppressive functions. In this study, we evaluated the effect of cAMP-elevating agents on human CD4+CD25+ T cells, which include the T regulatory cells (Tregs) that play a pivotal role in the maintenance of immunological tolerance. We found that cAMP elevating agents induce upregulation of CTLA-4 in CD4+CD25- and further enhance its expression in CD4+CD25+ T cells. We observed an increase of two isoforms of mRNA coding for the membrane and the soluble CTLA-4 molecules, suggesting that the regulation of CTLA-4 expression by cAMP is at the transcriptional level. In addition, we found that the increase of cAMP in CD4+CD25+ T cells converts the CD4+CD25+Foxp3- T cells in CD4+CD25+Foxp3+ T cells, whereas the increase of cAMP in CD4+CD25- T cells did not upregulate Foxp3 in the absence of activation stimuli. To investigate the function of these cells, we performed an in vitro suppression assay by culturing CD4+CD25+ T cells untreated or pre-treated with CT with anti-CD3 mAbs-stimulated autologous peripheral blood mononuclear cell. We found that CT enhances the inhibitory function of CD4+CD25+ T cells, CD4+, and CD8+ T cell proliferation and IFNgamma production are strongly inhibited by CD4+CD25+ T cells pre-treated with cAMP-elevating agents. Furthermore, we found that CD4+CD25+ T lymphocytes pre-treated with cAMP-elevating agents induce the upregulation of CD80 and CD86 co-stimulatory molecules on immature dendritic cells (DCs) in the absence of antigenic stimulation, however without leading to full DC maturation. These data show that the increase of intracellular cAMP modulates the phenotype and function of human CD4+CD25+ T cells. PMID- 27703458 TI - DRI-Grass: A New Experimental Platform for Addressing Grassland Ecosystem Responses to Future Precipitation Scenarios in South-East Australia. AB - Climate models predict shifts in the amount, frequency and seasonality of rainfall. Given close links between grassland productivity and rainfall, such changes are likely to have profound effects on the functioning of grassland ecosystems and modify species interactions. Here, we introduce a unique, new experimental platform - DRI-Grass (Drought and Root Herbivore Interactions in a Grassland) - that exposes a south-eastern Australian grassland to five rainfall regimes [Ambient (AMB), increased amount (IA, +50%), reduced amount (RA, -50%), reduced frequency (RF, single rainfall event every 21 days, with total amount unchanged) and summer drought (SD, 12-14 weeks without water, December-March)], and contrasting levels of root herbivory. Incorporation of a belowground herbivore (root-feeding scarabs) addition treatment allows novel investigation of ecological responses to the twin stresses of altered rainfall and root herbivory. We quantified effects of permanently installed rain shelters on microclimate by comparison with outside plots, identifying small shelter effects on air temperature (-0.19 degrees C day, +0.26 degrees C night), soil water content (SWC; -8%) and photosynthetically active radiation (PAR; -16%). Shelters were associated with modest increases in net primary productivity (NPP), particularly during the cool season. Rainfall treatments generated substantial differences in SWC, with the exception of IA; the latter is likely due to a combination of higher transpiration rates associated with greater plant biomass in IA and the low water-holding capacity of the well-drained, sandy soil. Growing season NPP was strongly reduced by SD, but did not respond to the other rainfall treatments. Addition of root herbivores did not affect plant biomass and there were no interactions between herbivory and rainfall treatments in the 1st year of study. Root herbivory did, however, induce foliar silicon-based defenses in Cynodon dactylon and Eragrostis curvula. Rapid recovery of NPP following resumption of watering in SD plots indicates high functional resilience at the site, and may reflect adaptation of the vegetation to historically high variability in rainfall, both within- and between years. DRI-Grass provides a unique platform for understanding how ecological interactions will be affected by changing rainfall regimes and, specifically, how belowground herbivory modifies grassland resistance and resilience to climate extremes. PMID- 27703456 TI - Cancers Related to Immunodeficiencies: Update and Perspectives. AB - The life span of patients with primary and secondary immunodeficiency is increasing due to recent improvements in therapeutic strategies. While the incidence of primary immunodeficiencies (PIDs) is 1:10,000 births, that of secondary immunodeficiencies are more common and are associated with posttransplantation immune dysfunction, with immunosuppressive medication for human immunodeficiency virus or with human T-cell lymphotropic virus infection. After infection, malignancy is the most prevalent cause of death in both children and adults with (PIDs). PIDs more often associated with cancer include common variable immunodeficiency (CVID), Wiskott-Aldrich syndrome, ataxia telangiectasia, and severe combined immunodeficiency. This suggests that a protective immune response against both infectious non-self-(pathogens) and malignant self-challenges (cancer) exists. The increased incidence of cancer has been attributed to defective elimination of altered or "transformed" cells and/or defective immunity towards cancer cells. The concept of aberrant immune surveillance occurring in PIDs is supported by evidence in mice and from patients undergoing immunosuppression after transplantation. Here, we discuss the importance of PID defects in the development of malignancies and the current limitations associated with molecular pathogenesis of these diseases and emphasize the need for further knowledge of how specific mutations can modulate the immune system to alter immunosurveillance and thereby play a key role in the etiology of malignancies in PID patients. PMID- 27703457 TI - Nod2: A Critical Regulator of Ileal Microbiota and Crohn's Disease. AB - The human intestinal tract harbors large bacterial community consisting of commensal, symbiotic, and pathogenic strains, which are constantly interacting with the intestinal immune system. This interaction elicits a non-pathological basal level of immune responses and contributes to shaping both the intestinal immune system and bacterial community. Recent studies on human microbiota are revealing the critical role of intestinal bacterial community in the pathogenesis of both systemic and intestinal diseases, including Crohn's disease (CD). NOD2 plays a key role in the regulation of microbiota in the small intestine. NOD2 is highly expressed in ileal Paneth cells that provide critical mechanism for the regulation of ileal microbiota through the secretion of anti-bacterial compounds. Genome mapping of CD patients revealed that loss of function mutations in NOD2 are associated with ileal CD. Genome-wide association studies further demonstrated that NOD2 is one of the most critical genetic factor linked to ileal CD. The bacterial community in the ileum is indeed dysregulated in Nod2-deficient mice. Nod2-deficient ileal epithelia exhibit impaired ability of killing bacteria. Thus, altered interactions between ileal microbiota and mucosal immunity through NOD2 mutations play significant roles in the disease susceptibility and pathogenesis in CD patients, thereby depicting NOD2 as a critical regulator of ileal microbiota and CD. PMID- 27703460 TI - Combining Image Analysis, Genome Wide Association Studies and Different Field Trials to Reveal Stable Genetic Regions Related to Panicle Architecture and the Number of Spikelets per Panicle in Rice. AB - Number of spikelets per panicle (NSP) is a key trait to increase yield potential in rice (O. sativa). The architecture of the rice inflorescence which is mainly determined by the length and number of primary (PBL and PBN) and secondary (SBL and SBN) branches can influence NSP. Although several genes controlling panicle architecture and NSP in rice have been identified, there is little evidence of (i) the genetic control of panicle architecture and NSP in different environments and (ii) the presence of stable genetic associations with panicle architecture across environments. This study combines image phenotyping of 225 accessions belonging to a genetic diversity array of indica rice grown under irrigated field condition in two different environments and Genome Wide Association Studies (GWAS) based on the genotyping of the diversity panel, providing 83,374 SNPs. Accessions sown under direct seeding in one environement had reduced Panicle Length (PL), NSP, PBN, PBL, SBN, and SBL compared to those established under transplanting in the second environment. Across environments, NSP was significantly and positively correlated with PBN, SBN and PBL. However, the length of branches (PBL and SBL) was not significantly correlated with variables related to number of branches (PBN and SBN), suggesting independent genetic control. Twenty- three GWAS sites were detected with P <= 1.0E-04 and 27 GWAS sites with p <= 5.9E-04. We found 17 GWAS sites related to NSP, 10 for PBN and 11 for SBN, 7 for PBL and 11 for SBL. This study revealed new regions related to NSP, but only three associations were related to both branching number (PBN and SBN) and NSP. Two GWAS sites associated with SBL and SBN were stable across contrasting environments and were not related to genes previously reported. The new regions reported in this study can help improving NSP in rice for both direct seeded and transplanted conditions. The integrated approach of high-throughput phenotyping, multi-environment field trials and GWAS has the potential to dissect complex traits, such as NSP, into less complex traits and to match single nucleotide polymorphisms with relevant function under different environments, offering a potential use for molecular breeding. PMID- 27703459 TI - Expansion and Functional Divergence of AP2 Group Genes in Spermatophytes Determined by Molecular Evolution and Arabidopsis Mutant Analysis. AB - The APETALA2 (AP2) genes represent the AP2 group within a large group of DNA binding proteins called AP2/EREBP. The AP2 gene is functional and necessary for flower development, stem cell maintenance, and seed development, whereas the other members of AP2 group redundantly affect flowering time. Here we study the phylogeny of AP2 group genes in spermatophytes. Spermatophyte AP2 group genes can be classified into AP2 and TOE types, six clades, and we found that the AP2 group homologs in gymnosperms belong to the AP2 type, whereas TOE types are absent, which indicates the AP2 type gene are more ancient and TOE type was split out of AP2 type and losing the major function. In Brassicaceae, the expansion of AP2 and TOE type lead to the gene number of AP2 group were up to six. Purifying selection appears to have been the primary driving force of spermatophyte AP2 group evolution, although positive selection occurred in the AP2 clade. The transition from exon to intron of AtAP2 in Arabidopsis mutant leads to the loss of gene function and the same situation was found in AtTOE2. Combining this evolutionary analysis and published research, the results suggest that typical AP2 group genes may first appear in gymnosperms and diverged in angiosperms, following expansion of group members and functional differentiation. In angiosperms, AP2 genes (AP2 clade) inherited key functions from ancestors and other genes of AP2 group lost most function but just remained flowering time controlling in gene formation. In this study, the phylogenies of AP2 group genes in spermatophytes was analyzed, which supported the evidence for the research of gene functional evolution of AP2 group. PMID- 27703461 TI - Genome-Wide Characterization of the MADS-Box Gene Family in Radish (Raphanus sativus L.) and Assessment of Its Roles in Flowering and Floral Organogenesis. AB - The MADS-box gene family is an important transcription factor (TF) family that is involved in various aspects of plant growth and development, especially flowering time and floral organogenesis. Although it has been reported in many plant species, the systematic identification and characterization of MADS-box TF family is still limited in radish (Raphanus sativus L.). In the present study, a comprehensive analysis of MADS-box genes was performed, and a total of 144 MADS box family members were identified from the whole radish genome. Meanwhile, a detailed list of MADS-box genes from other 28 plant species was also investigated. Through the phylogenetic analysis between radish and Arabidopsis thaliana, all the RsMADS genes were classified into two groups including 68 type I (31 Malpha, 12 Mbeta and 25Mgamma) and 76 type II (70 MIKCC and 6 MIKC*). Among them, 41 (28.47%) RsMADS genes were located in nine linkage groups of radish from R1 to R9. Moreover, the homologous MADS-box gene pairs were identified among radish, A. thaliana, Chinese cabbage and rice. Additionally, the expression profiles of RsMADS genes were systematically investigated in different tissues and growth stages. Furthermore, quantitative real-time PCR analysis was employed to validate expression patterns of some crucial RsMADS genes. These results could provide a valuable resource to explore the potential functions of RsMADS genes in radish, and facilitate dissecting MADS-box gene-mediated molecular mechanisms underlying flowering and floral organogenesis in root vegetable crops. PMID- 27703462 TI - The Rice Eukaryotic Translation Initiation Factor 3 Subunit e (OseIF3e) Influences Organ Size and Pollen Maturation. AB - Eukaryotic translation initiation factor 3 (eIF3) is a large protein complex that participates in most translation initiation processes. While eIF3 has been well characterized, less is known about the roles of individual eIF3 subunits, particularly in plants. Here, we identified and characterized OseIF3e in rice (Oryza sativa L.). OseIF3e was constitutively expressed in various tissues, but most strongly in vigorously growing organs. Transgenic OseIF3e-silenced rice plants showed inhibited growth in seedling and vegetative stages. Repression of OseIF3e led to defects in pollen maturation but did not affect pollen mitosis. In rice, eIF3e interacted with eIF3 subunits b, d, e, f, h, and k, and with eIF6, forming homo- and heterodimers to initiate translation. Furthermore, OseIF3e was shown by yeast two-hybrid assay to specifically bind to inhibitors of cyclin dependent kinases 1, 5, and 6. This interaction was mediated by the sequence of amino acid residues at positions 118-138, which included a conserved motif (IGPEQIETLYQFAKF). These results suggested although OseIF3e is not a "functional core" subunit of eIF3, it still plays crucial roles in rice growth and development, in combination with other factors. We proposed a pathway by which OseIF3e influence organ size and pollen maturation in rice, providing an opportunity to optimize plant architecture for crop breeding. PMID- 27703463 TI - Pectins, Endopolygalacturonases, and Bioenergy. AB - The precise disassembly of the extracellular matrix of some plant species used as feedstocks for bioenergy production continues to be a major barrier to reach reasonable cost effective bioethanol production. One solution has been the use of pretreatments, which can be effective, but increase even more the cost of processing and also lead to loss of cell wall materials that could otherwise be used in industry. Although pectins are known to account for a relatively low proportion of walls of grasses, their role in recalcitrance to hydrolysis has been shown to be important. In this mini-review, we examine the importance of pectins for cell wall hydrolysis highlighting the work associated with bioenergy. Here we focus on the importance of endopolygalacturonases (EPGs) discovered to date. The EPGs cataloged by CAZy were screened, revealing that most sequences, as well as the scarce structural work performed with EPGs, are from fungi (mostly Aspergillus niger). The comparisons among the EPG from different microorganisms, suggests that EPGs from bacteria and grasses display higher similarity than each of them with fungi. This compilation strongly suggests that structural and functional studies of EPGs, mainly from plants and bacteria, should be a priority of research regarding the use of pectinases for bioenergy production purposes. PMID- 27703464 TI - Genome-wide Association Study Identifies New Loci for Resistance to Sclerotinia Stem Rot in Brassica napus. AB - Sclerotinia stem rot (SSR) caused by the necrotrophic fungus Sclerotinia sclerotiorum is a major disease in rapeseed (Brassica napus) worldwide. Breeding for SSR resistance in B. napus, as in other crops, relies only on germplasms with quantitative resistance genes. A better understanding of the genetic basis for SSR resistance in B. napus thus holds promise for the genetic improvement of disease resistance. In the present study, a genome-wide association study (GWAS) for SSR resistance in B. napus were performed using an association panel of 448 accessions genotyped with the Brassica 60K Infinium(r) single-nucleotide polymorphism (SNP) array. A total of 26 SNPs corresponding to three loci, DSRC4, DSRC6, and DSRC8 were associated with SSR resistance. Haplotype analysis showed that the three favorable alleles for SSR resistance exhibited cumulative effects. After aligning SSR resistance quantitative trait loci (QTL) identified in the present and previous studies to the B. napus reference genome, one locus (DSRC6) was found to be located within the confidence interval of a QTL identified in previous QTL mapping studies and another two loci (DSRC4 and DSRC8) were considered novel loci for SSR resistance. A total of 39 candidate genes were predicted for the three loci based on the GWAS combining with the differentially expressed genes identified in previous transcriptomics analyses. PMID- 27703465 TI - Using the Disease State Fingerprint Tool for Differential Diagnosis of Frontotemporal Dementia and Alzheimer's Disease. AB - BACKGROUND: Disease State Index (DSI) and its visualization, Disease State Fingerprint (DSF), form a computer-assisted clinical decision making tool that combines patient data and compares them with cases with known outcomes. AIMS: To investigate the ability of the DSI to diagnose frontotemporal dementia (FTD) and Alzheimer's disease (AD). METHODS: The study cohort consisted of 38 patients with FTD, 57 with AD and 22 controls. Autopsy verification of FTD with TDP-43 positive pathology was available for 14 and AD pathology for 12 cases. We utilized data from neuropsychological tests, volumetric magnetic resonance imaging, single photon emission tomography, cerebrospinal fluid biomarkers and the APOE genotype. The DSI classification results were calculated with a combination of leave-one out cross-validation and bootstrapping. A DSF visualization of a FTD patient is presented as an example. RESULTS: The DSI distinguishes controls from FTD (area under the receiver-operator curve, AUC = 0.99) and AD (AUC = 1.00) very well and achieves a good differential diagnosis between AD and FTD (AUC = 0.89). In subsamples of autopsy-confirmed cases (AUC = 0.97) and clinically diagnosed cases (AUC = 0.94), differential diagnosis of AD and FTD performs very well. CONCLUSIONS: DSI is a promising computer-assisted biomarker approach for aiding in the diagnostic process of dementing diseases. Here, DSI separates controls from dementia and differentiates between AD and FTD. PMID- 27703466 TI - Progranulin Levels in Plasma and Cerebrospinal Fluid in Granulin Mutation Carriers. AB - BACKGROUND: Pathogenic mutations in the granulin gene (GRN) are causative in 5 10% of patients with frontotemporal dementia (FTD), mostly leading to reduced progranulin protein (PGRN) levels. Upcoming therapeutic trials focus on enhancing PGRN levels. METHODS: Fluctuations in plasma PGRN (n = 41) and its relationship with cerebrospinal fluid (CSF, n = 32) and specific single nucleotide polymorphisms were investigated in pre- and symptomatic GRN mutation carriers and controls. RESULTS: Plasma PGRN levels were lower in carriers than in controls and showed a mean coefficient of variation of 5.3% in carriers over 1 week. Although plasma PGRN correlated with CSF PGRN in carriers (r = 0.54, p = 0.02), plasma only explained 29% of the variability in CSF PGRN. rs5848, rs646776 and rs1990622 genotypes only partly explained the variability of PGRN levels between subjects. CONCLUSIONS: Plasma PGRN is relatively stable over 1 week and therefore seems suitable for treatment monitoring of PGRN-enhancing agents. Since plasma PGRN only moderately correlated with CSF PGRN, CSF sampling will additionally be needed in therapeutic trials. PMID- 27703467 TI - Modifiable Factors Associated with Cognitive Impairment in 1,143 Japanese Outpatients: The Project in Sado for Total Health (PROST). AB - BACKGROUND/AIMS: Evidence on modifiable factors associated with cognitive impairment in Japanese patients is scarce. This study aimed to determine modifiable factors for cognitive impairment in a Japanese hospital-based population. METHODS: Subjects of this cross-sectional study were 1,143 patients of Sado General Hospital (Niigata, Japan) registered in the Project in Sado for Total Health (PROST) between June 2008 and September 2014. We assessed disease history, body mass index (BMI), leisure time physical activity, walking time, smoking and drinking habits, and consumption of vegetables, fruits, and green tea as predictors, with cognitive impairment defined by the Mini-Mental State Examination (score <24) as an outcome. Multiple logistic regression analysis was performed to calculate odds ratios (ORs) for cognitive impairment. RESULTS: The mean subject age was 68.9 years, and the prevalence of cognitive impairment was 21.5%. Multivariate analysis revealed that age (p < 0.001), low BMI (<21.1; OR 1.39, 95% CI 1.12-1.72), a history of stroke (p = 0.003), a history of myocardial infarction (p = 0.038), low fruit consumption (p for trend = 0.012), and low green tea consumption (p for trend = 0.032) were independently associated with a higher prevalence of cognitive impairment. CONCLUSIONS: Modifiable factors, such as low BMI, low fruit consumption, and low green tea consumption, are associated with cognitive impairment. Longitudinal studies will be needed to confirm these findings. PMID- 27703468 TI - Decreased Physical Activity Associated with Executive Dysfunction Correlates with Cognitive Impairment among Older Adults in the Community: A Retrospective Analysis from the Kurihara Project. AB - BACKGROUND/AIMS: No previous studies have explored the relationship between physical activity (PA) and executive dysfunction. METHODS: We retrospectively evaluated the PA for 590 older participants in the Kurihara Project; 221 participants had a Clinical Dementia Rating (CDR) of 0 (healthy), 295 CDR 0.5 (very mild dementia), and 74 CDR 1+ (dementia). RESULTS: In the complicated task, whether the motor intensity was high (e.g. farming) or low (e.g. shopping), PA exhibited an inverse relationship with the CDR level. By contrast, for simple tasks with high intensity (e.g. walking), no CDR group differences were noted. For PA with low intensity (e.g. cleaning), the CDR 1+ group exhibited decreased levels. CONCLUSION: PA was related to the burden of executive function in patients with mild cognitive impairment; however, in patients with dementia, PA was related to both the burden of executive function and motor intensity. PMID- 27703469 TI - Does Schizophrenia in Offspring Increase the Risk of Developing Alzheimer's Dementia. AB - BACKGROUND/AIMS: Prior studies have consistently found a higher risk of dementia in individuals with schizophrenia, but whether this is due to a common etiology between the disorders remains obscure. We wanted to elucidate this association by investigating whether schizophrenia in offspring increases the risk of Alzheimer's dementia. METHODS: All individuals born between 1930 and 1953 were identified through national registers and followed from their 50th birthday until the date of Alzheimer's dementia, death or end of the study. Regressions were performed to evaluate the association between offspring with schizophrenia and Alzheimer's dementia. RESULTS: Individuals with offspring with schizophrenia did not have an increased risk of Alzheimer's dementia [incidence rate ratio (IRR), 0.97; 95% CI, 0.88-1.07] compared to individuals with offspring without psychiatric contact. This finding remained stable when evaluating early-onset (IRR, 1.10; 95% CI, 0.91-1.31) and late-onset Alzheimer's dementia (IRR, 0.92; 95% CI, 0.88-1.07). Similar findings were made for vascular and unspecified dementia. CONCLUSION: The finding of no familial coaggregation between schizophrenia and Alzheimer's dementia may suggest that no common etiology between the disorders exists. This may indicate that the excess risk of dementia in individuals with schizophrenia is a by-product of the higher rates of somatic comorbidity and adverse health risk factors among these individuals.

AB - BACKGROUND/AIMS: We investigated quantitative/qualitative changes of instrumental activities of daily living (IADL) in people with a Clinical Dementia Rating (CDR) of 0.5. METHODS: IADLs were evaluated in older residents: CDR of 0 (healthy) and CDR 0.5 (questionable/very mild dementia). The subjects with CDR 0.5 were divided into 2 types: the very mild Alzheimer's disease (vmAD) type and the other type including very mild subcortical vascular dementia. IADLs were evaluated quantitatively using the Lawton and the original qualitative IADL scales. RESULTS: CDR 0.5/vmAD type subjects had impairment of only one Lawton item (Shopping) compared to CDR 0 subjects. However, the CDR 0.5/vmAD type group and the CDR 0.5/other type group showed impairment of 3 items in the qualitative assessment (Shopping, Food preparation, and Mode of transportation). CONCLUSION: We suggest using both quantitative/qualitative IADL scales for assessing older adults with very mild dementia. PMID- 27703471 TI - Clinical Recommendations for the Use of Donepezil 23 mg in Moderate-to-Severe Alzheimer's Disease in the Asia-Pacific Region. AB - BACKGROUND: The 'Asia-Pacific Expert Panel (APEX) for donepezil 23 mg' met in November 2015 to review evidence for the recently approved high dose of donepezil and to provide recommendations to help physicians in Asia make informed clinical decisions about using donepezil 23 mg in patients with moderate-to-severe Alzheimer's disease (AD). SUMMARY: In a global phase III study (study 326) in patients with moderate-to-severe AD, donepezil 23 mg/day demonstrated significantly greater cognitive benefits versus donepezil 10 mg/day, with a between-treatment difference in mean change in the Severe Impairment Battery score of 2.2 points (p < 0.001) in the overall population and 3.1 points (p < 0.001) in patients with advanced AD. A subanalysis of study 326 demonstrated that the benefits and risks associated with donepezil 23 mg/day versus donepezil 10 mg/day in Asian patients with moderate-to-severe AD were comparable to those in the global study population. KEY MESSAGE: Donepezil 23 mg is a valuable treatment for patients with AD, particularly those with advanced disease. The APEX emphasized the importance of patient selection (AD severity, tolerability of lower doses of donepezil, and absence of contraindications), a stepwise titration strategy for dose escalation, and appropriate monitoring and counseling of patients and caregivers in the management of patients with AD.

AB - BACKGROUND/AIMS: There is evidence of an association between cognitive function and physical fitness. The aim of this study was to compare physical fitness in patients with cognitive impairment with a group of older people recently discharged from hospital. METHODS: A cross-sectional study with 98 patients recently diagnosed with cognitive impairment and 115 patients recently discharged from hospital. Associations between the study group variable and different components in the Senior fitness test were examined, controlling for demographic factors and comorbidity. RESULTS: The group recently diagnosed with cognitive impairment indicated poorer results on three of six physical fitness components (p < 0.05). CONCLUSION: Older adults with cognitive impairment are in need of individually tailored physical activity programs to increase the level of physical fitness.

To investigate the therapeutic safety, feasibility, and efficacy of endoclips for closing the endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) related duodenal perforation in a retrospective study from a single center. Methods. Patients who developed EUS and ERCP related duodenal perforation between January 2012 and January 2015 were included in the study. All the cases underwent endoscopic closure by endoclips, and the efficacy, feasibility, and safety of this technique were evaluated. Results. During the study period, a total of 17,406 patients were treated by EUS and/or ERCP. EUS and ERCP related duodenal perforation occurred in 9 cases (0.05%): 2 males and 7 females. The mean age was 69 years (range: 59-79 years). The success rate of endoscopic closure by endoclips was 100%. The mean procedure time was 45 +/- 12.5 min. The mean number of endoclips placed for the closure of the duodenal perforation was 7 +/- 3.2. All the patients recovered completely without any severe complications. Conclusion. The endoscopic closure by using endoclips is recommended as the first-line treatment for duodenal perforation associated with EUS and ERCP.

AB - A recent surge in the use of dietary supplements, including herbal remedies, necessitates investigations into their safety profiles. "Dream herb," Calea zacatechichi, has long been used in traditional folk medicine for a variety of purposes and is currently being marketed in the US for medicinal purposes, including diabetes treatment. Despite the inherent vulnerability of the renal system to xenobiotic toxicity, there is a lack of safety studies on the nephrotoxic potential of this herb. Additionally, the high frequency of diabetes associated kidney disease makes safety screening of C. zacatechichi for safety especially important. We exposed human proximal tubule HK-2 cells to increasing doses of this herb alongside known toxicant and protectant control compounds to examine potential toxicity effects of C. zacatechichi relative to control compounds. We evaluated both cellular and mitochondrial functional changes related to toxicity of this dietary supplement and found that even at low doses evidence of cellular toxicity was significant. Moreover, these findings correlated with significantly elevated levels of nephrotoxicity biomarkers, lending further support for the need to further scrutinize the safety of this herbal dietary supplement. PMID- 27703476 TI - Diet-Related Knowledge and Physical Activity in a Large Cohort of Insulin-Treated Type 2 Diabetes Patients: PROGENS ARENA Study. AB - There is no doubt that behavioral intervention is crucial for type 2 diabetes mellitus (T2DM) prevention and management. We aimed to estimate dietary habits and diet-oriented knowledge as well as the level of physical activity in 2500 insulin-treated Polish type 2 diabetes mellitus (T2DM) patients (55.4% women). The mean age of the study participants was 64.9 +/- 9.3 years, mean BMI was 31.4 kg/m2 +/- 4.5, mean diabetes duration was 12.4 +/- 6.9 years, and mean baseline HbA1c was 8.5% +/- 1.2. At the study onset, all the patients completed a questionnaire concerning health-oriented behavior. Results showed a significant lack of diet-related knowledge. For example, only 37.5% recognized that buckwheat contains carbohydrates; the percentage of correct answers in questions about fruit drinks and pasta was 56.4% and 61.2%, respectively. As for the physical activity, only 57.4% of examined T2DM patients declared any form of deliberate physical activity. To conclude, the cohort of poorly controlled insulin-treated T2DM patients studied by us is characterized by insufficient diet-related knowledge and by a very low level of physical activity. Further studies on other populations of insulin-treated T2DM patients are required to confirm these findings.

AB - In the study, type 2 diabetic rat model was established using streptozotocin (STZ) combined with a high-fat diet, and the rats were divided into control and diabetic groups. Diabetic groups were further divided into nonintervening, simvastatin, Didang Decoction (DDD) early-phase intervening, DDD mid-phase intervening, and DDD late-phase intervening groups. The expression level of MLCK was detected using Western Blot analysis, and the levels of cyclic adenosine monophosphate (cAMP), protein kinase C (PKC), and protein kinase A (PKA) were examined using Real Time PCR. Under the electron microscope, the cells in the early-DDD-intervention group and the simvastatin group were significantly more continuous and compact than those in the diabetic group. Compared with the control group, the expression of cAMP-1 and PKA was decreased in all diabetic groups, whereas the expression of MLCK and PKC was increased in early- and mid phase DDD-intervening groups (P < 0.05); compared with the late-phase DDD intervening group, the expression of cAMP-1 and PKA was higher, but the level of MLCK and PKC was lower in early-phase DDD-intervening group (P < 0.05). In conclusion, the early use of DDD improves the permeability of vascular endothelial cells by regulating the MLCK signaling pathway. PMID- 27703473 TI - Gender Differences in Adipocyte Metabolism and Liver Cancer Progression. AB - Liver cancer is the third most common cancer type and the second leading cause of deaths in men. Large population studies have demonstrated remarkable gender disparities in the incidence and the cumulative risk of liver cancer. A number of emerging risk factors regarding metabolic alterations associated with obesity, diabetes and dyslipidemia have been ascribed to the progression of non-alcoholic fatty liver diseases (NAFLD) and ultimately liver cancer. The deregulation of fat metabolism derived from excessive insulin, glucose, and lipid promotes cancer causing inflammatory signaling and oxidative stress, which eventually triggers the uncontrolled hepatocellular proliferation. This review presents the current standing on the gender differences in body fat compositions and their mechanistic linkage with the development of NAFLD-related liver cancer, with an emphasis on genetic, epigenetic and microRNA control. The potential roles of sex hormones in instructing adipocyte metabolic programs may help unravel the mechanisms underlying gender dimorphism in liver cancer and identify the metabolic targets for disease management.

Among the hypothesized contributors are the "low pH streptococci," a designation given to unusually acid proficient strains among the primary plaque colonizers S. oralis, S. mitis, S. gordonii, and S. anginosus. However, accurate assignment of species is difficult among the oral streptococci. Our objective was to develop a streamlined method for identifying strains of S. oralis and S. mitis from plaque samples so that they could be analyzed in a separate study devoted to low pH streptococci and caries. Two independent PCR amplifications of a locus highly conserved among streptococci were used for presumptive species identification. Multilocus sequence analysis (MLSA) was used to measure accuracy. Sensitivity was 100% for selecting S. oralis and S. mitis among the clones sampled. Specificity was good except for the most closely related species that could not be reliably distinguished even by MLSA. The results with S. oralis and S. mitis were used to identify new primer sets that expanded the utility of the approach to other oral streptococcal species. These novel primer sets offer a convenient means of presumptive identification that will have utility in many studies where large scale, in-depth genomic analyses are not practical. PMID- 27703480 TI - Glucose-6-Phosphate Dehydrogenase Deficiency and Sickle Cell Trait among Prospective Blood Donors: A Cross-Sectional Study in Berekum, Ghana. AB - Background. Blood transfusion is a therapeutic procedure usually undertaken in patients with severe anaemia. In Ghana, severe anaemia is mostly due to malaria caused by severe Plasmodium falciparum infection, road traffic accidents, and haemoglobinopathy-induced acute haemolysis. Method. This cross-sectional study evaluated coinheritance of sickle cell haemoglobin variant and G6PD enzymopathy among individuals that donated blood at the Holy Trinity Hospital, Berekum, in the Brong-Ahafo Region, Ghana. Demographic data and other pertinent information were captured using questionnaire. Sickle cell haemoglobin variants were determined using cellulose acetate electrophoresis (pH 8.6). Qualitative G6PD status and quantitative G6PD enzyme activity were determined using methaemoglobin reduction and Trinity Biotech G6PD test kit, respectively. Results. Prevalence of sickle cell trait (SCT) and G6PD enzymopathy coinheritance was 7%. In addition, 19.5% of the donors had 10%-60% of normal G6PD enzyme activity suggesting that these donor units are prone to stressor-induced acute haemolysis when given to recipients. Mild G6PD activity (p = 0.03, OR: 2.410 (CI: 1.049-5.534)), commercial (p = 0.020, OR: 5.609 (CI: 1.309-24.035)), and voluntary (p = 0.034, OR: 2.404 (CI: 1.071-5.397)) donors were significantly associated with SCT. Conclusion. Screening for red cell pathologies must be incorporated into existing protocols for populations with high incidence of haemoglobinopathies to protect high-risk recipients.

Antenatal care (ANC) attendance helps pregnant women to benefit from preventive and curative services. Methods. Determinants for ANC attendance were identified through a cross-sectional survey in the Democratic Republic of Congo. Sociocultural bottlenecks were assessed via focus groups discussion of married men and women. Results. In this survey, 28 of the 500 interviewed pregnant women (5.6%) did not attend ANC services and 82.4% booked over the first trimester. The first visit is positively influenced by the reproductive age (OR: 0.52, 95% CI(0.28-0.95), p < 0.04), the educational level (OR: 0.41,95% CI(0.17-0.97), p < 0.04), the nearby health center (OR: 0.43, 95% CI(0.2-0.92), p < 0.03), and the presence of a male partner (OR: 10.48, 95% CI(2.1-52.23), p < 0.001). The barriers to early booking were (i) the cost of service; (ii) the appearance or individual income; (iii) the geographical inaccessibility or distance to health facilities; (iv) social and religious prohibitions; (v) the stigmatization from other women when conceiving in the late ages or young or while still lactating (parity); (vi) the time for waiting for services. Conclusion. The early ANC attendance is delayed among poor women with little education and living alone. PMID- 27703483 TI - The Association of Pseudohypoparathyroidism Type Ia with Chiari Malformation Type I: A Coincidence or a Common Link? AB - A 19-month-old boy was referred for progressive weight gain. His past medical history included congenital hypothyroidism and developmental delay. Physical examination revealed characteristics of Albright Hereditary Osteodystrophy, macrocephaly, and calcinosis cutis. He had hypocalcemia, hyperphosphatemia, and elevated Parathyroid Hormone levels. Genetic testing revealed a known mutation of GNAS gene, confirming the diagnosis of Pseudohypoparathyroidism Type Ia (PHP-Ia) (c.34C>T (p.G1n12X)). He had a normal brain MRI at three months, but developmental delay prompted a repeat MRI that revealed Chiari Malformation Type I (CM-I) with hydrocephalus requiring neurosurgical intervention. This was followed by improvement in attaining developmental milestones. Recently, he was diagnosed with growth hormone deficiency. This case suggests the potential association of CM-I with PHP-Ia. Larger studies are needed to assess whether CM-I with hydrocephalus are common associations with PHP-Ia and to define potential genetic links between these conditions. We propose a low threshold in performing brain MRI on PHP-1a patients, especially those with persistent developmental delay to rule out CM-I. Early intervention may improve neurodevelopmental outcomes and prevent neurosurgical emergencies. PMID- 27703484 TI - Targeted Strategies to Modulate Stem-Cell-Relevant Pathways. PMID- 27703485 TI - Differential Characterization of Two Kinds of Stem Cells Isolated from Rabbit Nucleus Pulposus and Annulus Fibrosus. AB - Objective. Nucleus pulposus (NP) and annulus fibrosus (AF) are two main components of intervertebral disc (IVD). We aimed to figure out whether NP and AF also contain stem cells and whether these stem cells share common properties with chondrocytes and/or fibroblasts in their phenotypes or whether they are completely different types of cells with different characteristics. Design. The disk cells were isolated from AF and NP tissues of the same lumbar spine of the rabbits. The properties of these disk cells were characterized by their morphology, population doubling time (PDT), stem cell marker expression, and multidifferentiation potential using tissue culture techniques, immunocytochemistry, and RT-PCR. Results. Both disk cells formed colonies in culture and expressed stem cell markers, nucleostemin, Oct-4, SSEA-4, and Stro-1, at early passages. However, after 5 passages, AFSCs became elongated and NPSCs appeared senescent. Conclusion. This study indicated that IVD contains stem cells and the characteristics of AFSCs and NPSCs are intrinsically different. The findings of this study may provide basic scientific data for understanding the properties of IVD cells and the mechanisms of lower back pain.

AB - We retrospectively evaluated if personalized Kampo medicine (PKM) could facilitate CTL responses and clinical benefits induced by personalized peptide vaccination (PPV), in which HLA-matched vaccines were selected and administered based on the preexisting host immunity, for advanced esophageal cancer (aEC) patients. Among 34 aEC patients entered in the clinical study, 23 patients received PKM and PPV without (n = 12) or with chemotherapy (n = 11), while the remaining 11 patients did not receive PKM but received PPV without (n = 6) or with chemotherapy (n = 5), respectively. Incidence of adverse events was significantly lower or higher in PKM and PPV arm (n = 23) or PPV and chemotherapy arm (n = 16) as compared to that of the counter arm (n = 11 or 18), respectively. Postvaccination PBMCs from the patients undergoing PKM and PPV showed significantly higher CTL responses as compared to the counter arm. The median progression-free survival (PFS) or median survival time (MST) of 34 patients was 2.9 or 7.6 months, respectively. The combination therapy in PPV and PKM arm, but not that in PPV and chemotherapy arm, significantly (P = 0.02) prolonged MST. These results could warrant a next step of prospective clinical study of PKM and PPV for aEC patients.

PMID- 27703487 TI - Anti-Inflammatory Effects of Traditional Chinese Medicines against Ischemic Injury in In Vivo Models of Cerebral Ischemia. AB - Inflammation plays a crucial role in the pathophysiology of acute ischemic stroke. In the ischemic cascade, resident microglia are rapidly activated in the brain parenchyma and subsequently trigger inflammatory mediator release, which facilitates leukocyte-endothelial cell interactions in inflammation. Activated leukocytes invade the endothelial cell junctions and destroy the blood-brain barrier integrity, leading to brain edema. Toll-like receptors (TLRs) stimulation in microglia/macrophages through the activation of intercellular signaling pathways secretes various proinflammatory cytokines and enzymes and then aggravates cerebral ischemic injury. The secreted cytokines activate the proinflammatory transcription factors, which subsequently regulate cytokine expression, leading to the amplification of the inflammatory response and exacerbation of the secondary brain injury. Traditional Chinese medicines (TCMs), including TCM-derived active compounds, Chinese herbs, and TCM formulations, exert neuroprotective effects against inflammatory responses by downregulating the following: ischemia-induced microglial activation, microglia/macrophage mediated cytokine production, proinflammatory enzyme production, intercellular adhesion molecule-1, matrix metalloproteinases, TLR expression, and deleterious transcription factor activation. TCMs also aid in upregulating anti-inflammatory cytokine expression and neuroprotective transcription factor activation in the ischemic lesion in the inflammatory cascade during the acute phase of cerebral ischemia. Thus, TCMs exert potent anti-inflammatory properties in ischemic stroke and warrant further investigation. PMID- 27703489 TI - Myricitrin Protects against Doxorubicin-Induced Cardiotoxicity by Counteracting Oxidative Stress and Inhibiting Mitochondrial Apoptosis via ERK/P53 Pathway. AB - Doxorubicin (Dox) is one of the most effective and widely used anthracycline antineoplastic antibiotics. Unfortunately, the use of Dox is limited by its cumulative and dose-dependent cardiac toxicity. Myricitrin, a natural flavonoid which is isolated from the ground bark of Myrica rubra, has recently been found to have a strong antioxidative effect. This study aimed to evaluate the possible protective effect of myricitrin against Dox-induced cardiotoxicity and the underlying mechanisms. An in vivo investigation in SD rats demonstrated that myricitrin significantly reduced the Dox-induced myocardial damage, as indicated by the decreases in the cardiac index, amelioration of heart pathological injuries, and decreases in the serum cardiac enzyme levels. In addition, in vitro studies showed that myricitrin effectively reduced the Dox-induced cell toxicity. Further study showed that myricitrin exerted its function by counteracting oxidative stress and increasing the activities of antioxidant enzymes. Moreover, myricitrin suppressed the myocardial apoptosis induced by Dox, as indicated by decreases in the activation of caspase-3 and the numbers of TUNEL-positive cells, maintenance of the mitochondrial membrane potential, and increase in the Bcl 2/Bax ratio. Further mechanism study revealed that myricitrin-induced suppression of myocardial apoptosis relied on the ERK/p53-mediated mitochondrial apoptosis pathway. PMID- 27703491 TI - Computational Hemodynamic Analysis for the Diagnosis of Atherosclerotic Changes in Intracranial Aneurysms: A Proof-of-Concept Study Using 3 Cases Harboring Atherosclerotic and Nonatherosclerotic Aneurysms Simultaneously. AB - This was a proof-of-concept computational fluid dynamics (CFD) study designed to identify atherosclerotic changes in intracranial aneurysms. We selected 3 patients with multiple unruptured aneurysms including at least one with atherosclerotic changes and investigated whether an image-based CFD study could provide useful information for discriminating the atherosclerotic aneurysms. Patient-specific geometries were constructed from three-dimensional data obtained using rotational angiography. Transient simulations were conducted under patient specific inlet flow rates measured by phase-contrast magnetic resonance velocimetry. In the postanalyses, we calculated time-averaged wall shear stress (WSS), oscillatory shear index, and relative residence time (RRT). The volume of blood flow entering aneurysms through the neck and the mean velocity of blood flow inside aneurysms were examined. We applied the age-of-fluid method to quantitatively assess the residence of blood inside aneurysms. Atherosclerotic changes coincided with regions exposed to disturbed blood flow, as indicated by low WSS and long RRT. Blood entered aneurysms in phase with inlet flow rates. The mean velocities of blood inside atherosclerotic aneurysms were lower than those inside nonatherosclerotic aneurysms. Blood in atherosclerotic aneurysms was older than that in nonatherosclerotic aneurysms, especially near the wall. This proof of-concept study demonstrated that CFD analysis provided detailed information on the exchange and residence of blood that is useful for the diagnosis of atherosclerotic changes in intracranial aneurysms. PMID- 27703492 TI - A Fetal Electrocardiogram Signal Extraction Algorithm Based on Fast One-Unit Independent Component Analysis with Reference. AB - Fetal electrocardiogram (FECG) extraction is very important procedure for fetal health assessment. In this article, we propose a fast one-unit independent component analysis with reference (ICA-R) that is suitable to extract the FECG. Most previous ICA-R algorithms only focused on how to optimize the cost function of the ICA-R and payed little attention to the improvement of cost function. They did not fully take advantage of the prior information about the desired signal to improve the ICA-R. In this paper, we first use the kurtosis information of the desired FECG signal to simplify the non-Gaussian measurement function and then construct a new cost function by directly using a nonquadratic function of the extracted signal to measure its non-Gaussianity. The new cost function does not involve the computation of the difference between the function of the Gaussian random vector and that of the extracted signal, which is time consuming. Centering and whitening are also used to preprocess the observed signal to further reduce the computation complexity. While the proposed method has the same error performance as other improved one-unit ICA-R methods, it actually has lower computation complexity than those other methods. Simulations are performed separately on artificial and real-world electrocardiogram signals. PMID- 27703493 TI - Analysis of Blood Transfusion Data Using Bivariate Zero-Inflated Poisson Model: A Bayesian Approach. AB - Recognizing the factors affecting the number of blood donation and blood deferral has a major impact on blood transfusion. There is a positive correlation between the variables "number of blood donation" and "number of blood deferral": as the number of return for donation increases, so does the number of blood deferral. On the other hand, due to the fact that many donors never return to donate, there is an extra zero frequency for both of the above-mentioned variables. In this study, in order to apply the correlation and to explain the frequency of the excessive zero, the bivariate zero-inflated Poisson regression model was used for joint modeling of the number of blood donation and number of blood deferral. The data was analyzed using the Bayesian approach applying noninformative priors at the presence and absence of covariates. Estimating the parameters of the model, that is, correlation, zero-inflation parameter, and regression coefficients, was done through MCMC simulation. Eventually double-Poisson model, bivariate Poisson model, and bivariate zero-inflated Poisson model were fitted on the data and were compared using the deviance information criteria (DIC). The results showed that the bivariate zero-inflated Poisson regression model fitted the data better than the other models. PMID- 27703494 TI - Alterations of caveolin-1 expression in a mouse model of delayed cerebral vasospasm following subarachnoid hemorrhage. AB - The aim of the present study was to evaluate the expression levels of caveolin-1 in the basilar artery following delayed cerebral vasospasm (DCVS) in a rat model of subarachnoid hemorrhage (SAH), in order to investigate the association between caveolin-1 and DCVS, and its potential as a treatment for DCVS of SAH. A total of 150 Sprague Dawley rats were randomly allocated into blank, saline and SAH groups. The SAH and saline groups were subdivided into days 3, 5, 7 and 14 following the establishment of the model. The murine model of SAH was established by double injection of autologous arterial blood into the cisterna magana and DCVS was detected using Bederson neurological severity scores. Hematoxylin and eosin (HE) staining was used to observe the inner perimeter of the basilar artery pipe and variations in the thickness of the basilar artery wall. Alterations in the levels of caveolin-1 protein in the basilar artery were measured using immunofluorescence and western blot analysis; whereas alterations in the mRNA expression levels of caveolin-1 were detected by reverse transcription quantitative polymerase chain reaction. In the present study, 15 mice succumbed to SAH-induced DCVS in the day 3 (n=3), 5 (n=5) and 7 (n=2) groups. No mortality was observed in the blank control and saline groups during the process of observation in the SAH group, All mice in the SAH groups exhibited Bederson neurological severity scores >=1; whereas no neurological impairment was detected in the blank and normal saline groups, demonstrating the success of the model. HE staining was used to assess vasospasm and the results demonstrated that the inner perimeter of the basal artery pipe decreased at day 3 in the SAH group; whereas values peaked in the day 7 group. The thickness of the basal artery wall significantly increased (P<0.05), as compared with the blank and saline groups, in which no significant alterations in the wall thickness and the inner perimeter of the basal artery pipe were detected. As detected by immunofluorescence and western blot analysis, the expression levels of caveolin-1 protein significantly decreased in the day 7 of SAH group, as compared with the blank and saline groups (P<0.01), in which no significant alterations were detected. Caveolin-1 mRNA expression levels significantly increased at the day 7 in the SAH group, as compared with the blank and the saline groups (P<0.01), as detected by RT-qPCR. Furthermore, significant differences were detected at day 14 in the SAH group, as compared with the blank and the saline groups (P>0.05), in which no significant alterations were detected. Therefore, the results of the present study demonstrated that caveolin-1 protein was downregulated in the basilar artery of a rat modeling SAH, which may be associated with DCVS. This suggested that caveolin 1 may be a potential target for the treatment of DCVS. PMID- 27703495 TI - Identification of hub genes and pathways associated with hepatocellular carcinoma based on network strategy. AB - The objective of this study was to identify hub genes and pathways associated with hepatocellular carcinoma (HCC) by centrality analysis of a co-expression network. A co-expression network based on differentially expressed (DE) genes of HCC was constructed using the Differentially Co-expressed Genes and Links (DCGL) package. Centrality analyses, for centrality of degree, clustering coefficient, closeness, stress and betweenness for the co-expression network were performed to identify hub genes, and the hub genes were combined together to overcome inconsistent results. Enrichment analyses were conducted using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases. Finally, validation of hub genes was conducted utilizing reverse transcription-polymerase chain reaction (RT PCR) analysis. In total, 260 DE genes between normal controls and HCC patients were obtained and a co-expression network with 154 nodes and 326 edges was constructed. From this, 13 hub genes were identified according to degree, clustering coefficient, closeness, stress and betweenness centrality analysis. It was found that reelin (RELN), potassium voltage-gated channel subfamily J member 10 (KCNJ10) and neural cell adhesion molecule 1 (NCAM1) were common hub genes across the five centralities, and the results of RT-PCR analysis for RELN, KCNJ10 and NCAM1 were consistent with the centrality analyses. Pathway enrichment analysis of DE genes showed that cell cycle, metabolism of xenobiotics by cytochrome P450 and p53 signaling pathway were the most significant pathways. This study may contribute to understanding the molecular pathogenesis of HCC and provide potential biomarkers for its early detection and effective therapies. PMID- 27703496 TI - HBD-3 regulation of the immune response and the LPS/TLR4-mediated signaling pathway. AB - The aim of the study was to investigate the mechanisms of human beta-defensin 3 (HBD-3) regulation of the immune response and the lipopolysaccharide/Toll-like receptor-4 (LPS/TLR4)-mediated signaling pathway. A TLR4 extracellular gene fragment was cloned into the pET32a plasmid to determine its expression in Escherichia coli (E. coli) and purification. A dialysis labeling method was used to stain HBD-3 with fluorescein isothiocyanate (FITC). FITC-HBD-3 was used to induce the differentiation of human peripheral blood mononuclear cells (MNC) into immature dendritic cells (imDC) in vitro. Binding reactions were established using FITC-HBD-3 and sTLR4 into cell suspensions. Flow cytometry (FCM) was used to analyze the results. Western blot analysis confirmed the identity of nuclear factor-kappaB (NF-kappaB) and was used to quantify its nuclear translocation. The results showed that, HBD-3 bound to imDC in a Ca2+-dependent manner, and sTLR4 and LPS competitively inhibited the binding. HBD-3 competitively blocked the binding of LPS and imDC by binding to imDC. HBD-3 significantly decreased the translocation of LPS-induced NF-kappaB into the nucleus. In conclusion, HBD-3 can competitively inhibit the binding of LPS and imDC through its binding to TLR4 molecules, which are expressed in imDC, thereby preventing LPS from inducing the maturity of the imDCs. PMID- 27703497 TI - Chronic myelocytic leukemic fundus lesion: A case report. AB - The current study reports a case of a patient with a chronic myelocytic leukemic fundus lesion, initially diagnosed in the Department of Ophthalmology, Rizhao People's Hospital (Rizhao, China). A male, 23-years-of-age, presented with a dark shadow in the front of the right eye, accompanied with blurred vision for 3 days (visual acuity of right eye, 0.4; visual acuity of left eye, 0.6). In addition, the patient had experienced gingival bleeding for 2 years, and recurrent upper respiratory infections for 1 year. A fundus examination revealed mild binocular papillary edema, dilated and tortuous veins, and the retina exhibited large quantities of scattered and dark red bleeding spots. The bleeding spots had white spots in the center, which exhibited typical Roth spots, whilst routine blood examination, abdominal ultrasound, marrow biopsy and other laboratory tests confirmed the diagnosis of chronic myelogenous leukemia. Patients with leukemia typically present with initial symptoms that include fever, fatigue, anemia and hepatosplenomegaly, and a diagnosis as a result of eye-related symptoms is rare, rendering the present case unique. PMID- 27703498 TI - Acute transverse myelitis and subacute thyroiditis associated with dengue viral infection: A case report and literature review. AB - Acute transverse myelitis is a rare manifestation of dengue infection. To the best of our knowledge, only 6 cases of acute transverse myelitis as a manifestation of dengue infection have been reported thus far. The present study described a case of acute transverse myelitis complicated with subacute thyroiditis 6 days after the onset of dengue viral infection. In addition, the available literature was searched to identify similar previous cases. Treatment with intravenous pulse methylprednisolone immunoglobulin plasmapheresis and physiotherapy resulted in partial recovery at 3 months post-infection. In conclusion, the involvement of dengue infection should be considered in patients who develop central nervous system manifestations during or after the recovery period of dengue infection. Furthermore, since methylprednisolone and immunoglobulin are effective during the active phase of the infection, prompt diagnosis and initiation of treatment are crucial. PMID- 27703499 TI - FeNO for detecting lower airway involvement in patients with allergic rhinitis. AB - Allergic rhinitis (AR) is a risk factor for asthma development. The value of fractional exhaled nitric oxide (FeNO) in detecting lower airway involvement in the progress of AR-asthma march has not been evaluated. The aim of the present study was to investigate the value of FeNO in assessing lower airway inflammation and predicting bronchial hyperresponsiveness (BHR) in AR with or without asthma. FeNO and eosinophil count in induced sputum, and a methacholine bronchial provocation test were performed in 93 subjects, including: 45 AR patients (AR group); 20 patients with AR and asthma (AR with asthma group); and 28 normal controls (control group). The AR group was divided into two sub-groups: AR with asymptomatic BHR group and AR without BHR group. Correlation between FeNO and eosinophil count was assessed. Receiver operating characteristic (ROC) curve was applied to evaluate the predictive and diagnostic value of FeNO in detecting BHR. The values of FeNO in the AR and AR with asthma groups were higher [29.5 (22.0) ppb and 61.5 (33.0) ppb] compared with the normal control group (16.0 (10.0) ppb), where the values in brackets indicate the interquartile range of the values. The percentages of eosinophils in induced sputum were 2.43+/-3.56, 7.36+/ 4.98 and 18.58+/-11.26% in the control, AR and AR with asthma groups, respectively. For the diagnosis of BHR, the area under the curve (AUC) was 0.910 (95%CI 0.836, 0.984), with the sensitivity and specificity 0.846 and 0.817 when the cut-off value takes 31.5 ppb. For diagnosis of asthma, the AUC was 0.873 (95%CI 0.753, 0.992) with sensitivity 0.857 and specificity 0.847 when taking the cut-off value to be 38.0 ppb. The value of FeNO was well correlated with eosinophil count in the sputum. The measurement of FeNO is an effective method in detecting lower airway involvement in AR developing to asthma. PMID- 27703500 TI - Childhood type 2 diabetes: Risks and complications. AB - The universal endocrine pathological state affecting young individuals and adults is type 2 diabetes mellitus, which has seen a significant increase in the last 30 years, particularly in children. Genetic and evnironmental factors are the causative agents for this pathological state in children. This rapid and wide spread of the disease can be controlled by enforcing amendments in environmental factors such as diet, physical activities and obesity. In young infants breastfeeding may be a key modulator of the disease. Associated disorders co observed in the patients of type 2 diabetes mellitus include renal failure, heart problems and circulatory dysfunctionalities, such as cardiac failure and vision disability. These associated disorders become more pronounced in young patients when they reach puberty. To overcome the lethal outcomes of the disease, early screening of the disease is crucial. The present review focused on the latest updates in the field, as well as plausible risks and complications of this pathological state. PMID- 27703503 TI - Telemedicine in clinical setting. AB - The telemedicine department of a hospital is an emerging branch in upcoming hospitals and may become an essential component of every hospital. It basically utilizes the information technologies along with telecommunication systems in order to provide clinical care and assistance. Furthermore, the branch of telemedicine offers significant opportunities for the process of developmental freedom from illness, early death, and preventable diseases. It advances development by providing relevant drugs and the necessary care aimed to alleviate patient suffering. It is also beneficial for patients in rural remote areas who usually do not have adequate access to advanced hospitals. Telemedicine in these remote areas allows for timely treatment of emergency cases. Thus, it contributes towards remote emergency critical care in order to save lives in crucial cases. Additionally, the emerging advances have now enabled telemedicine to transfer large amounts of clinical informatics data including images, and test reports to the specifically specialized health professionals in some serious cases. However, as in the case of many emerging technologies, organizing information and understanding the field has significant challenges. The present review article aimed to discuss important aspects of the field with regard to the better management of patients in clinical settings. PMID- 27703501 TI - Hypersplenism: History and current status. AB - Hypersplenism is a common disorder characterized by an enlarged spleen which causes rapid and premature destruction of blood cells. This review summarizes the history of hypersplenism, discuss its classification and pathogenesis, and examines its diagnosis and treatment options. We performed a comprehensive literature search using PubMed, Web of Knowledge and the China National Knowledge Infrastructure (CNKI) database, reviewed hypersplenism-related articles and summarized the major findings. According to its etiological causes, hypersplenism is characterized by splenomegaly and peripheral cytopenias. It can be classified into three categories: i) primary hypersplenism; ii) secondary hypersplenism; and iii) occult hypersplenism. A number of mechanisms causing hypersplenism have been identified, and mainly involve retention in the spleen, phagocytosis, and autoimmunity. Treatment options for hypersplenism include etiological treatment, non-surgical treatment, total splenectomy and liver transplantation. In any case, treatment should be individualized for each patient. PMID- 27703504 TI - Small hepatocyte-like progenitor cells may be a Hedgehog signaling pathway controlled subgroup of liver stem cells. AB - The present study aimed to investigate the expression levels of components of the Hedgehog signaling pathway (HH) during the proliferation of a liver stem cell subgroup, namely small hepatocyte-like progenitor cells (SHPCs). Retrorsine treated Fisher 344 rats underwent a partial hepatectomy (PH) to induce the proliferation of SHPCs, after which reverse transcription-polymerase chain reaction (PCR), quantitative PCR, immunohistochemistry and western blot analysis were performed to analyze the expression of various components of the HH in primary SHPCs at different times points post-PH. A number of components of the HH, including Indian hedgehog (IHH), patched (PTCH), smoothened and glioma associated oncogene (GLI)1, 2 and 3, were continuously expressed and showed dynamic changes in proliferating SHPCs. In addition, the expression levels of IHH, PTCH and GLI1 were significantly different as compared with those of the control group at the same time point, and there were significant differences among the various time points in the experimental group (P<0.01). Furthermore, there was an association between the postoperative day and expression levels of HH components in the retrorsine-treated group. An immunohistochemical analysis demonstrated that PTCH was also expressed at the protein level. In conclusion, the results of the present study suggested that the HH was continuously activated during the proliferation of SHPCs, thus indicating that SHPCs may be a subgroup of stem cells that are regulated by the HH. PMID- 27703502 TI - Obesity and hypertension. AB - The imbalance between energy intake and expenditure is the main cause of excessive overweight and obesity. Technically, obesity is defined as the abnormal accumulation of >=20% of body fat, over the individual's ideal body weight. The latter constitutes the maximal healthful value for an individual that is calculated based chiefly on the height, age, build and degree of muscular development. However, obesity is diagnosed by measuring the weight in relation to the height of an individual, thereby determining or calculating the body mass index. The National Institutes of Health have defined 30 kg/m2 as the limit over which an individual is qualified as obese. Accordingly, the prevalence of obesity in on the increase in children and adults worldwide, despite World Health Organization warnings. The growth of obesity and the scale of associated health issues induce serious consequences for individuals and governmental health systems. Excessive overweight remains among the most neglected public health issues worldwide, while obesity is associated with increasing risks of disability, illness and death. Cardiovascular diseases, the leading cause of mortality worldwide, particularly hypertension and diabetes, are the main illnesses associated with obesity. Nevertheless, the mechanisms underlying obesity-associated hypertension or other associated metabolic diseases remains to be adequately investigated. In the present review, we addressed the association between obesity and cardiovascular disease, particularly the biological mechanisms linking obesity and hypertension. PMID- 27703505 TI - Computational approach for predicting the conserved B-cell epitopes of hemagglutinin H7 subtype influenza virus. AB - An avian-origin influenza H7N9 virus epidemic occurred in China in 2013-2014, in which >422 infected people suffered from pneumonia, respiratory distress syndrome and septic shock. H7N9 viruses belong to the H7 subtype of avian-origin influenza viruses (AIV-H7). Hemagglutinin (HA) is a vital membrane protein of AIV that has an important role in host recognition and infection. The epitopes of HA are significant determinants of the regularity of epidemic and viral mutation and recombination mechanisms. The present study aimed to predict the conserved B-cell epitopes of AIV-H7 HA using a bioinformatics approach, including the three most effective epitope prediction softwares available online: Artificial Neural Network based B-cell Epitope Prediction (ABCpred), B-cell Epitope Prediction (BepiPred) and Linear B-cell Epitope Prediction (LBtope). A total of 24 strains of Euro-Asiatic AIV-H7 that had been associated with a serious poultry pandemic or had infected humans in the past 30 years were selected to identify the conserved regions of HA. Sequences were obtained from the National Center for Biotechnology Information and Global Initiative on Sharing Avian Influenza Data databases. Using a combination of software prediction and sequence comparisons, the conserved epitopes of AIV-H7 were predicted and clarified. A total of five conserved epitopes [amino acids (aa) 37-52, 131-142, 215-234, 465-484 and 487 505] with a suitable length, high antigenicity and minimal variation were predicted and confirmed. Each obtained a score of >0.80 in ABCpred, 60% in LBtope and a level of 0.35 in Bepipred. In addition, a representative amino acid change (glutamine235-to-leucine235) in the HA protein of the 2013 AIV-H7N9 was discovered. The strategy adopted in the present study may have profound implications on the rapid diagnosis and control of infectious disease caused by H7N9 viruses, as well as by other virulent viruses, such as the Ebola virus. PMID- 27703506 TI - A meta-analysis of the effects of beta-adrenergic blockers in chronic heart failure. AB - Adrenergic beta-blockers are drugs that bind to, but do not activate beta adrenergic receptors. Instead they block the actions of beta-adrenergic agonists and are used for the treatment of various diseases such as cardiac arrhythmias, angina pectoris, myocardial infarction, hypertension, headache, migraines, stress, anxiety, prostate cancer, and heart failure. Several meta-analysis studies have shown that beta-blockers improve the heart function and reduce the risks of cardiovascular events, rate of mortality, and sudden death through chronic heart failure (CHF) of patients. The present study identified results from recent meta-analyses of beta-adrenergic blockers and their usefulness in CHF. Databases including Medline/Embase/Cochrane Central Register of Controlled Trials (CENTRAL), and PubMed were searched for the periods May, 1985 to March, 2011 and June, 2013 to August, 2015, and a number of studies identified. Results of those studies showed that use of beta-blockers was associated with decreased sudden cardiac death in patients with heart failure. However, contradictory results have also been reported. The present meta-analysis aimed to determine the efficacy of beta-blockers on mortality and morbidity in patients with heart failure. The results showed that mortality was significantly reduced by beta blocker treatment prior to the surgery of heart failure patients. The results from the meta-analysis studies showed that beta-blocker treatment in heart failure patients correlated with a significant decrease in long-term mortality, even in patients that meet one or more exclusion criteria of the MERIT-HF study. In summary, the findings of the current meta-analysis revealed beneficial effects different beta-blockers have on patients with heart failure or related heart disease. PMID- 27703507 TI - Association between insulin resistance and estrogen in sexual precocity of obese children. AB - The aim of the study was to examine the association between sexual precocity and high-molecular weight (HMW)-adiponectin and investigate the correlation of insulin resistance and estrogen levels in obese children. In total, 60 obese children (30 boys and 30 girls) with sexual precocity were included in group A, 60 obese children (30 boys and 30 girls) without sexual precocity were included in group B, and 60 average weight children (30 boys and 30 girls) were included in group C. The levels of HMW adiponectin, fasting blood glucose, fasting insulin, luteinizing hormone (LH) peak, estradiol and testosterone were measured. The results showed that the HMW-adiponectin level of group A was the lowest and that of group C was the highest. The difference was statistically significant (P<0.05). The homeostasis model assessment of insulin resistance (HOMA-IR) and estradiol levels of group A were significantly higher than those of group B, and group B was higher than that of group C. LH peak and testosterone levels of group A were the lowest while those of group C were the highest. The differences were statistically significant (P<0.05). A subgroup analysis showed that the above results were more significant in girls. The Pearson correlation analysis revealed that the level of HMW-adiponectin was negatively correlated with HOMA-IR and estradiol (P<0.05), and positively correlated with the LH peak (P<0.05). In conclusion, sexual precocity of obese children may be associated with insulin resistance, and the link may be HMW-adiponectin. PMID- 27703508 TI - Diffusion tensor imaging of occult injury of optic radiation following optic neuritis in multiple sclerosis. AB - Multiple sclerosis (MS) is easily detected by routine magnetic resonance imaging (MRI). However, it is not possible to detect early or occult lesions in MS by routine MRI, and this may explain the inconsistency between the severity of the lesions found by MRI and the degree of clinical disability of patients with MS. The present study included 10 patients with relapsing-remitting MS and 10 healthy volunteers. Each patient underwent routine 3.0 T MRI, diffusion tensor imaging (DTI), and diffusion tensor tractography (DTT). Optic nerve and optic radiation were analyzed by DTI and DTT. The fractional anisotropy (FA), mean diffusivity (MD), lambda//, and lambda? values were measured. In the 10 patients with MS, 7 optic nerves were affected, and 13 optic nerves were not affected. Cranial MRI showed that optic nerve thickening and hyperintensity occurred in 2 patients with MS. In the directionally encoded color maps, a hypointensive green signal in the optic nerve was observed in 3 patients with MS. The FA values were significantly lower and the MD, lambda//, and lambda? values were significantly higher in the affected and unaffected optic nerves and optic radiations in patients with MS in comparison with controls (P<0.05). There were no significant differences in these values between the affected and unaffected optic nerves and optic radiation in patients with MS (P>0.05). Diffusion tensor imaging is sensitive in the detection of occult injury of the optic nerve and optic radiation following optic neuritis. Diffusion tensor imaging may be a useful tool for the early diagnosis, treatment and management of MS. PMID- 27703509 TI - Influence of random urine albumin-creatinine ratio of pregnant women with hypertension during the gestation period on perinatal outcome. AB - The aim of the present study was to investigate the influence of the random urine albumin-creatinine ratio (ACR) of pregnant women with hypertension during the gestation period on perinatal outcome. A total of 6,758 pregnant women with pregnancy-induced hypertension and proteinuria were randomly selected between September, 2009 and June, 2015 for the study. Kidney function, blood pressure, history of gravidity and parity, embryo number and the birth weight of the participants was determined. Logistic regression and paired data correlation analyses were carried out with kidney function, blood pressure, history of gravidity and parity, embryo number, birth weight, maternal age, labor presentation and other risk factors as the independent variables and the newborn APGAR score as the dependent variable. The results showed that random urine ACR was increased and negatively correlated with the APGAR score (OR=-0.095, P=0.017). In conclusion, the increased random urine ACR can influence the postpartum outcome. Early intervention of women of childbearing age in early pregnancy or before pregnancy can minimize the adverse complications of infants and mothers such as pregnancy hypertension syndrome, and improve the outcome of the pregnancy. PMID- 27703510 TI - Ginsenoside Rb1 protects the intestinal mucosal barrier following peritoneal air exposure. AB - Ginsenoside Rb1 (GRb1), which is one of the main ingredients derived from Panax ginseng, has been widely used to treat various gastrointestinal disorders. The present study aimed to determine whether GRb1 was able to prevent intestinal mucosal barrier damage in rats following peritoneal air exposure for 3 h. GRb1 (5, 10, and 20 mg/kg) was orally administrated via gavage four times prior to and following surgery. Blood and terminal ileum were sampled 24 h following surgery. Levels of serum D-lactate (D-LA) were detected using an enzyme-linked immunosorbent assay kit. Intestinal permeability was assessed by determining the intestinal clearance of fluorescein isothiocyanate-dextran (FD4). Activity of intestinal myeloperoxidase was measured to assess intestinal inflammation, and intestinal histopathology was assessed by light microscopy. The results showed that GRb1 reduced the level of serum D-LA, intestinal clearance of FD4, and the activity of intestinal myeloperoxidase. Intestinal edema and inflammation were also ameliorated by GRb1, and the Chiu's scores employed for assessing intestinal mucosal damage were also reduced in the GRb1-treated peritoneal air exposure group. In addition, GRb1 induced a significant difference at 10 and 20 mg/kg, indicating a dose-dependent effect. The results of the present study suggest that GRb1 may be able to protect the intestinal mucosal barrier against damage induced by peritoneal air exposure, which may be associated with its anti-inflammatory action. PMID- 27703511 TI - Effect of systemic injection of heterogenous and homogenous opioids on peripheral cellular immune response in rats with bone cancer pain: A comparative study. AB - Exogenous and endogenous opioids have been shown to modulate the immune system. Morphine-induced immunosuppression has been investigated extensively. However, the immune-regulating function of endogenous opioid peptides is unclear. The present study aimed to evaluate the difference in effects on cellular immune function between recombinant rat beta-endorphin (beta-EP; 50 ug/kg) and plant source morphine (10 mg/kg) via intraperitoneal injection treatment in a rat model of bone cancer pain. Walker 256 cells were injected into a tibial cavity injection to establish the bone cancer pain model. The paw withdrawal thresholds and body weights were measured prior to surgery, at 6 days after surgery, and following 1, 3,6 and 8 treatments. The spleen cells were harvested for detection of T cell proliferation, natural killer (NK) cell cytotoxicity, and the relative quantities of T cell subtypes (CD3+, CD4+ and CD8+ cells). Plasma levels of interleukin-2 (IL-2) were also determined. It was found that single or multiple treatments with beta-EP (a homogenous opioid peptide) and morphine (a heterogenous opioid) had good analgesic effects on bone cancer pain, while the analgesia provided by morphine was stronger than that of beta-EP. Treatment with beta-EP 3, 6 and 8 times increased the body weight gain in the rat model of bone cancer pain, while morphine treatment had on effect on it. With regard to immunomodulatory functions, beta-EP treatment increased T cell proliferation and NK cell cytotoxicity, and increased the relative quantities of T cell subtypes, but no effect on T cell secretion. However, morphine treatment decreased T cell proliferation and the levels of T cell subtypes. These data indicate that opioids from different sources have different effects on cellular immune function in vivo. A small dose of homogenous opioid peptide exhibited positive effects (analgesia and immune enhancement) on cancer pain. These results provide experimental evidence supporting the exploitation of human opioids for the treatment of cancer pain. PMID- 27703512 TI - Expression of Toll-like receptor 4 in lungs of immune-suppressed rat with Acinetobacter baumannii infection. AB - Toll-like receptor 4 (TLR4) is involved in the regulation of host responses to Acinetobacter baumannii (A. baumannii). The aim of the present study was to examine the function of TLR4 in lung inflammation in immune-suppressed rats with A. baumannii infection. A total of 72 Sprague-Dawley male rats were randomly divided into the control, A. baumannii infection and immune-suppressed infection groups. The immune-suppressed infection group was treated with 100 mg/kg hydrocortisone by subcutaneous injection every other day for 2 weeks prior to A. baumannii infection. Lung tissue was obtained on the 3rd and 7th day after tracheal inoculation with A. baumannii. The expression of TLR4 in bronchial and alveolar epithelial cells, and alveolar macrophage was examined using immunohistochemistry. The levels of interleukin (IL)-6, tumor necrosis factor (TNF)-alpha in bronchoalveolar lavage fluid were detected using ELISA. The results showed that in the control group, the expression of TLR4 was upregulated in the bronchial and alveolar epithelial, and alveolar macrophages, and the levels of IL-6 and TNF-alpha were increased in the early phase of A. baumannii infection. On the 7th day, no significant difference in the levels of IL-6 and TNF-alpha was observed between the A. baumannii infection and control groups. Conversely, the expression of TLR4 was downregulated in the immune-suppressed group, and the levels of IL-6 and TNF-alpha were reduced on the 3rd day after infection. In the subsequent observation period, the expression of TLR4 was upregulated and the levels of IL-6 and TNF-alpha were increased. In conclusion, the results show a critical role of TLR4 in mediating effective immune response in the lung of rat with A. baumannii infection. PMID- 27703513 TI - Clinical characteristics of drug-induced liver injury and related risk factors. AB - Drug-induced liver injury (DILI) is often undiagnosed or misdiagnosed clinically because of diagnostic difficulties caused by lack of laboratory-specific serological markers. In this study, we comprehensively assessed the clinical characteristics, laboratory indices, hepatotoxic drugs, risk factors and outcomes concerning DILI, and explored the similarities in mechanisms between Chinese and Western drug-induced DILI. Patients with a first diagnosis of DILI and a Roussel Uclaf Causality Assessment Method (RUCAM) score >3 points were enrolled for systematic retrospective study. Their clinical characteristics, clinical classification, risk factors, laboratory indices, hepatotoxic drugs and outcomes were analyzed. Cholestatic patients had the highest alkaline phosphatase (ALP) and prothrombin time activity (PTA) levels (P<0.05). Patients with medication time >=30 days had significantly higher positive rate of autoantibodies than those with medication time <30 days. Odds ratio values for DILI-related factors such as hepatobiliary diseases, immune dysfunction, diabetes, hypertension, chronic alcohol consumption and age >=45 years were 6.552, 6.130, 3.774, 2.801, 2.002 and 1.838, respectively. Pathogeneses of Chinese and Western drug-induced DILI may be substantially the same. DILI accompanied with autoantibody positivity may indicate severe liver injury outcome. Hepatobiliary diseases, diabetes and hypertension are likely to increase drug susceptibility, and more prone to cause liver injury. PMID- 27703514 TI - Association between socioeconomic status and oral health behaviors: The 2008-2010 Korea national health and nutrition examination survey. AB - Socioeconomic status (SES) has been reported to be associated with oral health behavior. Therefore, the present study was conducted to assess the relationship between SES and oral health behaviors in a large sample of the Korean population. Data from the Korea National Health and Nutrition Examination Survey, which was conducted between 2008 and 2010 by the Division of Chronic Disease Surveillance under the Korea Centers for Disease Control and Prevention and the Korean Ministry of Health and Welfare, were used in the present study. Daily tooth brushing frequency and the use of secondary oral products according to demographic variables and anthropometric characteristics of the participants were assessed. Multivariate logistic regression analyses were used to analyze the associations between daily tooth brushing frequency and the use of secondary oral products, and SES, urban/rural residence, body mass index (BMI), alcohol intake and smoking. An association between SES and tooth brushing frequency and the use of secondary oral products was detected after adjustment. Following adjustment for age, gender, BMI, smoking, drinking, exercise, energy intake, fat intake, periodontal treatment needs and education or income, the adjusted odds ratios and 95% confidence intervals (CI) of tooth brushing >=3 per day in the highest income group were 1.264 (95% CI, 1.094-1.460) and 2.686 (95% CI, 2.286-3.155) for highest education level group. The adjusted odds ratios for the use of secondary oral products in the highest income and highest education groups were 1.835 (95% CI, 1.559-2.161) and 5.736 (95% CI, 4.734-6.951), respectively, after adjustment for age, gender, smoking, BMI, exercise, calorie intake, periodontal treatment requirements or income. The present study demonstrated an association between SES and oral health behaviors in a large sample of the Korean population. Within the limits of the present study, income and education were suggested as potential risk indicators for oral health behaviors; therefore, patients with a low SES should be investigated further, in relation to oral health. PMID- 27703515 TI - Screening and identification of microRNA involved in unstable angina using gene chip analysis. AB - Increasing evidence has suggested that microRNA (miRNA) may play a role in the pathogenesis of cardiovascular disease, which has led to a greater understanding of the complex pathophysiological processes underlying unstable angina (UA). The present study aimed to investigate changes in the miRNA expression profiles of patients with UA using gene-chip analysis, in order to further elucidate the pathogenesis of UA. Total RNA was extracted and purified from plasma samples collected from patients with UA and healthy controls. The samples underwent microarray analysis using an Exiqon miRCURY LNATM microRNA Array. Differentially expressed miRNAs were identified by volcano plot filtering, and were validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). In addition, functional annotation of the differentially expressed miRNAs involved gene ontology analyses. Among the 212 miRNAs differentially expressed between the two groups, 82 were upregulated and 130 were downregulated. Notably, the results of the RT-qPCR were consistent with the gene-chip results. The miRNAs identified in the present study may be potential novel biomarkers for the prevention and early diagnosis of UA. Furthermore, the results of the present study suggested that UA occurs as a result of complex and dynamic processes regulated by numerous factors, including multiple miRNAs. PMID- 27703516 TI - Shikonin inhibits inflammation and chondrocyte apoptosis by regulation of the PI3K/Akt signaling pathway in a rat model of osteoarthritis. AB - Shikonin has previously been shown to have antitumor, anti-inflammatory, antiviral and extensive pharmacological effects. The aim of the present study was to explore whether the protective effect of shikonin is mediated via the inhibition of inflammation and chondrocyte apoptosis, and to elucidate the potential molecular mechanisms in a rat model of osteoarthritis. A model of osteoarthritis was established in healthy male Sprague-Dawley rats and 10 mg/kg/day shikonin was administered intraperitoneally for 4 days. It was found that shikonin treatment significantly inhibited inflammatory reactions in the rats with osteoarthritis. Osteoarthritis was found to significantly increase interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha and inducible nitric oxide synthase (iNOS) levels compared with those in the sham group. However, shikonin treatment significantly inhibited the increases in IL-1beta, TNF-alpha and iNOS levels in the rats with osteoarthritis. Furthermore, caspase-3 activity and cyclooxygenase (COX)-2 protein expression were significantly increased and phosphorylated Akt protein expression was greatly suppressed in rats with osteoarthritis when compared with the sham group. Shikonin administration attenuated the changes in caspase-3 activity and COX-2 expression and Akt phosphorylation in rats with osteoarthritis. These results indicate that shikonin inhibits inflammation and chondrocyte apoptosis by regulating the phosphoinositide 3-kinase/Akt signaling pathway in a rat model of osteoarthritis. PMID- 27703517 TI - FOXP3+ associated with the pro-inflammatory regulatory T and T helper 17 effector cells in asthma patients. AB - Asthma is a chronic bronchial inflammation that results to reversible incidence of airway obstruction and shortness of breath. Under normal circumstances, the lung immune system is maintained in a state of controlled inflammation, where balance exists between protective immunity mediated by effector cells and tolerance mediated by cells with regulatory function. Therefore, the inflammation observed in asthma patients may be caused by an imbalance between regulatory T (Treg) cells (CD4-positive with high expression of CD25 surface markers) and forkhead box P3 (FOXP3)-positive pro-inflammatory T helper 17 (Th17) cells. The aim of the present study was to evaluate whether reduced Treg cells and increased Th17 cells could be observed in the peripheral blood samples of asthma patients. As important markers of Treg cells, the expression levels of FOXP3 and interleukin (IL)-17a were analyzed via reverse trancription-quantitative polymerase chain reaction. The results indicated that the levels of cytokines that promote Th17 cells, including IL-6, IL-23 and TGF-beta, were found to increase in the bronchoalveolar lavage fluid sample of asthma patients. However, the IL-10 level in the corresponding sample was much lower compared with that in control individuals. In conclusion, these results suggest that asthma associated with a reduced proportion of Treg and Th17 cells in the blood is characterized by the expression of pro-inflammatory cytokines that may be beneficial for the continuous generation of Th17 cells. PMID- 27703518 TI - Gemstone spectral imaging for measuring adult bone mineral density. AB - The present study aimed to detect the bone Ca2+ content of L3 vertebrae in adults by gemstone spectral computed tomography. In total, 235 patients were selected and divided into age groups of 10 years each. The scanning data were used to detect the water-based and Ca2+-based substance levels on the L3 vertebral cancellous bone images. The results indicated that there were significant differences in vertebral Ca2+-water and water-Ca2+ densities determined by gemstone spectral imaging (GSI) between males and females in subjects aged 50-59 years, 60-69 years, 70-79 years and >=80 years (P<0.05). The ages of male and female participants were negatively correlated with vertebral Ca2+-water density (P<0.01) and water-Ca2+ density (P<0.01). In conclusion, GSI may be used as a novel method of measuring the vertebral adult bone mineral density. PMID- 27703520 TI - Thermal ablation in cancer. AB - Radiofrequency ablation (RFA) and cryoablation are alternative forms of therapy used widely in various pathological states, including treatment of carcinogenesis. The reason is that ablation techniques have ability of modulating the immune system. Furthermore, recent studies have applied this form of therapy on tumor microenvironment and in the systematic circulation. Moreover, RFA and cryoablation result in an inflammatory immune response along with tissue disruption. Evidence has demonstrated that these procedures affect carcinogenesis by causing a significant local inflammatory response leading to an immunogenic gene signature. The present review enlightens the current view of these techniques in cancer. PMID- 27703519 TI - Re-irradiation alternatives for recurrent high-grade glioma. AB - Despite advances in the fields of surgery, chemotherapy and radiotherapy, the prognosis for high-grade glioma (HGG) remains unsatisfactory. The majority of HGG patients experience disease recurrence. To date, no standard treatments have been established for recurrent HGG. Repeat surgery and chemotherapy demonstrate moderate efficacy. As recurrent lesions are usually located within the previously irradiated field, a second course of irradiation was once considered controversial, as it was considered to exhibit unsatisfactory efficacy and radiation-related toxicities. However, an increasing number of studies have indicated that re-irradiation may present an efficacious treatment for recurrent HGG. Re-irradiation may be delivered via conventionally fractionated stereotactic radiotherapy, hypofractionated stereotactic radiation therapy, stereotactic radiosurgery and brachytherapy techniques. In the present review, the current literature regarding re-irradiation treatment for recurrent HGG is summarized with regard to survival outcome and side effects. PMID- 27703521 TI - Caveolin-1 is overexpressed in hypopharyngeal squamous cell carcinoma and correlates with clinical parameters. AB - The present study aimed to identify the role of caveolin-1 (CAV1) in hypopharyngeal squamous cell carcinoma (HSCC) and identify its possible correlation with tumor clinical parameters. Expression of CAV1 was measured using immunohistochemical staining of 66 HSCC samples and 44 samples from morphologically normal tissues adjacent to the carcinomas. Expression of CAV1 in HSCC and paracancerous tissues were 71.2 and 9.5% respectively. Levels of CAV1 expression were significantly associated with tumor differentiation, tumor-node metastasis stage and lymph nodes metastasis (P<0.05). The present study identified that expression of CAV1 in HSCC is significantly higher than in paracancerous tissues, suggesting that this high expression of CAV1 is associated with tumor invasion and metastasis. PMID- 27703522 TI - SREBP-1 is an independent prognostic marker and promotes invasion and migration in breast cancer. AB - Re-programming of lipogenic signaling has been previously demonstrated to result in significant alterations in tumor cell pathology. Sterol regulatory element binding protein 1 (SREBP-1) is a known transcription factor of lipogenic genes. Despite the fact that its functions in proliferation and apoptosis have been elucidated in recent studies, its role in tumor cell migration and invasion, particularly in breast cancer, remains unclear. In present study, the messenger RNA and protein expression levels of SREBP-1 in cancer tissues were observed to be overexpressed compared with those in matched para-cancerous tissues (P<0.01). SREBP-1 level was highly positively correlated with tumor differentiation (P<0.001), tumor-node-metastasis stage (P=0.044) and lymph node metastasis (P<0.001). High expression of SREBP-1 predicted poor prognosis in patients with breast cancer. Additionally, multivariate analysis revealed that SREBP-1 was an independent factor of 5-year overall and disease-specific survival in breast cancer patients (P<0.01). In vitro studies revealed that the suppression of SREBP 1 expression in both MDA-MB-231 and MCF7 cells significantly inhibited cell migration and invasion (P<0.01). The present data indicate that SREBP-1 plays a critical role in breast cancer migration and invasion, and may serve as a prognostic marker of this malignancy. PMID- 27703523 TI - Mean platelet volume provides beneficial diagnostic and prognostic information for patients with resectable gastric cancer. AB - Gastric cancer is the fourth most frequent cancer and the second cause of cancer related mortalities worldwide. Platelets play an important and multifaceted role in cancer progression. Elevated mean platelet volume (MPV) detected in peripheral blood has been identified in various types of cancer. In the present study, we investigated the application value of MPV in early diagnostic and prognostic prediction in patients with resectable gastric cancer. In total, 168 patients with resectable gastric cancer were included and separated into the gastric cancer and healthy control groups according to median pre-operatic MPV value (MPV low, <10.51 or MPV high, >=10.51). The results showed that the pre-operatic MPV level was significantly higher in gastric cancer patients compared with the healthy subjects. Low pre-operatic MPV level correlated with improved clinicopathological features, including decreased depth of invasion, less lymphonodus metastasis and early tumor stage. The Kaplan-Meier plots showed that the patients with higher pre-operatic MPV had decreased overall survival (OS) and disease-free survival (DFS). Surgical tumor resection resulted in a significant decrease in the MPV level. The patients whose MPV level decreased following surgery had an improved OS. Multivariate Cox regression analysis revealed that the depth of invasion, lymphonodus metastasis, American Joint Committee on Cancer (AJCC) stage, and changes in MPV following surgery were prognostic factors affecting OS, and the AJCC stage and pre-operatic MPV were prognostic factors affecting DFS. In conclusion, MPV measurement can provide important diagnostic and prognostic results in patients with resectable gastric cancer. PMID- 27703525 TI - Novel recombinant protein FlaA N/C increases tumor radiosensitivity via NF-kappaB signaling in murine breast cancer cells. AB - The recombinant protein flagellin A (FlaA) N/C, derived from the flagellin protein of Legionella pneumophila, has been shown to increase the expression of cytoprotective cytokines, activate the nuclear factor-kappaB (NF-kappaB) signaling pathway, and increase the survival of mice following total body irradiation. Determi ning whether FlaA N/C has a sensitizing effect on tumor radiation or a direct tumoricidal effect is critical for its application as an effective radiation protection agent. The present study investigated the molecular mechanism underlying the tumor radiosensitivity of FlaA N/C. FlaA N/C was found to increase tumor apoptosis and autophagy, regulate the cell cycle and increase radiosensitivity in 4T1 tumor cells. Furthermore, FlaA N/C was found to promote radiosensitivity by activating NF-kappaB signaling. Finally, the present study analyzed FlaA N/C-enhanced radiosensitivity in animal models, and FlaA N/C was found to significantly prolong the survival period of mice after total body radiation. This indicates that FlaA N/C might be a novel radiation sensitizer in tumor radiation therapy. PMID- 27703524 TI - Methylation pattern of CDH1 promoter and its association with CDH1 gene expression in cytological cervical specimens. AB - Cervical cancer is the fourth leading cause of cancer mortality in females worldwide. Infection with high-risk human papillomavirus (HPV) is essential but insufficient to cause cervical cancer, and the clearance of HPV infection is mediated by the immune system. The deficit of molecules responsible for adhesion may play a role in the development of cervical cancer. E-cadherin is encoded by the cadherin 1 (CDH1) gene, and is involved in cell adhesion by forming adherens junctions. The aim of present study was to investigate the methylation pattern of the CDH1 promoter and to identify the association between CDH1 promoter hypermethylation, CDH1 gene expression and HPV infection in cervical specimens obtained from 93 patients with low-grade squamous intraepithelial lesions (SILs), high-grade SILs or squamous cell carcinomas, and from 47 patients with normal cervical cytology (HPV-negative). The methylation pattern of the CDH1 promoter was investigated by methylation-specific polymerase chain reaction and quantitative pyrosequencing. CDH1 gene expression was measured by relative quantification. CDH1 methylation was significantly higher in both types of lesions and in cervical cancer than in normal samples, and CDH1 gene expression was significantly reduced during SIL progression (P=0.0162). However, the influence of HPV infection or HPV E6 expression on the methylation pattern of the CDH1 gene or its gene expression levels could not be confirmed. The present results support that the methylation of the CDH1 gene is age-related in patients with cervical lesions (P=0.01085), and therefore, older patients could be more susceptible to cancer than younger patients. The important methylation of the CDH1 promoter occurred near the transcription factor binding sites on nucleotides -13 and +103, which are close to the translational start codon. These results suggest that methylation at these sites may be an important event in the transcriptional regulation of E-cadherin, and in patients harboring these methylated cytosines, this event may facilitate HPV-driven carcinogenesis. PMID- 27703526 TI - Ki-67 is overexpressed in human laryngeal carcinoma and contributes to the proliferation of HEp2 cells. AB - Ki-67 is one of the most useful markers to evaluate cell proliferative activity and has been widely used in tumor treatment and research. However, its role in human laryngeal carcinoma remains poorly defined. The aim of the present study was to investigate the expression of Ki-67 in human laryngeal squamous carcinoma and the effect of Ki-67 gene silencing by small interfering (si)RNA on the proliferation of human laryngocarcinoma HEp2 cells. Immunohistochemistry and reverse transcription-quantitative polymerase chain reaction were performed to examine the expression of Ki-67 in human laryngeal squamous carcinoma tissues and adjacent non-cancer tissues from 50 patients with laryngeal squamous carcinoma. RNA interference was used to knock down the expression of Ki-67 in the HEp2 cell line, and the proliferation of the treated cells was observed in vitro. Western blot analysis was used to determine the expression levels of epidermal growth factor receptor (EGFR) and E-cadherin in the treated cells. The expression of Ki 67 in the laryngeal squamous carcinoma tissues was significantly higher than that of the adjacent non-tumor tissues (P=0.028). The high expression of Ki-67 in cancer was significantly correlated with cervical lymph node metastasis and clinical outcomes (all P<0.001). The silencing of Ki-67 resulted in the inhibition of proliferation of the HEp2 human laryngocarcinoma cells (P<0.001). In addition, compared with the control group, the expression levels of EGFR and E cadherin in the Ki-67 siRNA-treated cells were significantly decreased (P<0.001) and increased (P<0.001), respectively. These results suggested that Ki-67 is important in regulating the proliferation of human laryngocarcinoma HEp2 cells and that the mechanism may at least partially be associated with the upregulation of EGFR and the downregulation of E-cadherin. Overall, Ki-67 can be used as an important indicator for judging clinical progress and estimating prognosis in human laryngeal squamous carcinoma. PMID- 27703527 TI - V8 induces apoptosis and the endoplasmic reticulum stress response in human multiple myeloma RPMI 8226 cells via the PERK-eIF2alpha-ATF4 signaling pathway. AB - Multiple myeloma (MM) is a fatal hematological cancer characterized by clonal plasma cell proliferation in the bone marrow. MM has an increasing global incidence and a poor prognosis. There are limited treatment options available for MM, and this is further compounded by the development of drug resistance. The present study demonstrated that 7-{4-[Bis-(2-hydroxyethyl)-amino]-butoxy}-5 hydroxy-8-methoxy-2-phenylchromen-4-one (V8), a novel synthetic flavonoid, induced apoptosis in human MM RPMI 8226 cells in a dose- and time-dependent manner, using cell viability assays and flow cytometry. Subsequently, V8-induced apoptosis in RPMI 8226 cells was revealed to occur via mitochondria-mediated pathways. The activity of caspase-3, -8 and -9, and the mRNA level of B-cell lymphoma 2 (Bcl-2) and B-cell lymphoma-extra large were greatly increased, while the expression of Bcl-2-like protein 4 and BH3 interacting domain death agonist was significantly decreased in RPMI 8226 cells following V8 treatment, as observed using quantitative polymerase chain reaction (qPCR). In addition, western blotting revealed that the release of mitochondrial cytochrome c into the cytosol was promoted by V8. Furthermore, a clear alteration in endoplasmic reticulum (ER) stress was observed in cells treated with V8; upregulation of glucose-regulated protein (GRP) 78, GRP94, C/EBP homologous protein, cleavage of caspase-12, phosphorylated protein kinase RNA-like endoplasmic reticulum kinase (p-PERK), phosphorylated eukaryotic initiation factor 2alpha (p-eIF2alpha) and activating transcription factor 4 (ATF4) was observed with qPCR and western blotting, suggesting that V8-induced apoptosis is involved in the ER stress response. Overall, the present results demonstrated that V8 induced apoptosis in human MM RPMI 8226 cells via the PERK-eIF2alpha-ATF4 ER stress response pathway, which may provide novel directions for exploiting this compound as a potential anti-neoplastic drug for MM therapy. PMID- 27703528 TI - Molecular expression of vascular endothelial growth factor, prokineticin receptor 1 and other biomarkers in infiltrating canalicular carcinoma of the breast. AB - Vascular endothelial growth factor (VEGF) is important in the growth and metastasis of cancer cells. In 2001, another angiogenic factor, endocrine gland derived VEGF (EG-VEGF), was characterized and sequenced. EG-VEGF activity appears to be restricted to endothelial cells derived from endocrine glands. At the molecular level, its expression is regulated by hypoxia and steroid hormones. Although VEGF and EG-VEGF are structurally different, they function in a coordinated fashion. Since the majority of mammary tumors are hormone-dependent, it was hypothesized that EG-VEGF would be expressed in these tumors, and therefore, represent a potential target for anti-angiogenic therapy. The aim of the present study was to assess the expression of VEGF, EG-VEGF and its receptor (prokineticin receptor-1), as well as that of breast cancer resistant protein, estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2, in 50 breast samples of infiltrating canalicular carcinoma (ICC) and their correlation with tumor staging. The samples were analyzed using reverse transcription-quantitative polymerase chain reaction and immunohistochemistry. Both angiogenic growth factors were identified in all samples. However, in 90% of the samples, the expression level of VEGF was significantly higher than that of EG-VEGF (P=0.024). There was no association between the expression of VEGF, EG VEGF or its receptor with tumor stage. In ICC, the predominant angiogenic factor expressed was VEGF. The expression level of either factor was not correlated with the tumor-node-metastasis stage. Although ICC is derived from endothelial cells, EG-VEGF expression was not the predominant angiogenic/growth factor in ICC. PMID- 27703529 TI - Rescuing defective tumor-infiltrating T-cell proliferation in glioblastoma patients. AB - Primary glioblastoma (GBM) is the most prevalent brain cancer, with fast progression and a poor prognosis. Current treatment options are unable to fully manage GBM since it is highly resistant to radiation and chemotherapy, and it cannot be completely removed by surgery. Thus, immunotherapeutic strategies utilizing tumor-infiltrating T cells have been investigated. In the present study, the T-cell response in GBM patients was examined in resected tumor samples and peripheral blood samples by flow cytometry. It was found that tumor infiltrating T cells represented a rare population in all tumor cells, and were more refractory to anti-cluster of differentiation 3 (CD3) stimulation than their peripheral blood counterparts. A number of strategies were then assessed to boost tumor-infiltrating T-cell proliferation, and it was found that pre-incubation with 20 U/ml interleukin (IL)-2, as well as sequestration of IL-10 in culture, improved tumor T-cell proliferation following anti-CD3 stimulation. The stimulation of blood antigen-presenting cells by lipopolysaccharide, however, did not improve tumor T-cell proliferation. Overall, the present results provided a viable strategy for improving tumor-infiltrating CD3+ T-cell responses in GBM patients. PMID- 27703530 TI - Contrary melanoma-associated antigen-A expression at the tumor front and center: A comparative analysis of stage I and IV head and neck squamous cell carcinoma. AB - There is a growing body of evidence indicating that several melanoma-associated antigen-A (MAGE-A) subgroups contribute to the malignancy of head and neck cancer. The present study retrospectively analyzed the expression of all known MAGE-A subgroups in the tumor front and center of 38 head and neck cancer patients (Union for International Cancer Control stage I or IV) by immunohistochemistry. MAGE-A1, -A6, -A8, -A9 and -A11 were expressed at significantly higher levels at the tumor front of stage IV specimens compared with the tumor front of stage I specimens. In stage I cancer, the tumor center and front ratio (C/F ratio) for each subgroup was >1.0. In stage IV cancer, the C/F ratio was <1.0 in 9/11 subgroups. The most significant change in the expression pattern was observed for MAGE-A11. These results indicated that there is a marked alteration and shift to the invasive front of almost all MAGE-A subgroups, but particularly MAGE-A11, during the progression of head and neck squamous cell carcinoma. PMID- 27703532 TI - Overlap of the cancer genome atlas and the immune epitope database. AB - Mutant peptides resulting from cancer drivers or passenger mutations are expected to have the potential to serve as a basis for cancer vaccines. However, a number of parameters regulate vaccine-associated immunogenicity, including the suitability of a peptide for binding to an antigen-presenting molecule or antibody. In order to obtain a basic indication of the prospect of human cancer epitope identification via current database development strategies, an overlap of the mutant Homo sapiens epitopes listed on the Immune Epitope Database (IEDB) and the mutant peptides indicated by The Cancer Genome Atlas (TCGA) somatic mutation database was obtained. No putative TCGA mutant peptides were detected among the 8,890 14-18 amino acid (AA) IEDB peptides available. In total, 3 IEDB mutant epitopes that encompassed a TCGA mutant AA position, but did not overlap the exact position of the TCGA mutant AA, were detected. The results of the present analysis confirm that verification of certain aspects of cancer epitope function can be obtained via the continued and systematic expansion of databases representing human protein epitopes. However, the analysis also indicates that there is relatively limited systematic information available regarding antigen presenting molecule epitopes and cancer-related mutant peptides. PMID- 27703533 TI - Solving medical mysteries: hidden stresses and unexplained symptoms. AB - Medically unexplained symptoms and chronic functional syndromes are common but few healthcare professionals have had formal training about their connection to psychosocial issues. A systematic approach to diagnosis and treatment based on experience with over 7000 of these patients is described. Outcomes improve with assessment for and treatment of current life stresses, the prolonged impact of adversity in childhood and somatic presentations of depression, post-traumatic stress, and anxiety disorders. PMID- 27703531 TI - Lithium chloride has a biphasic effect on prostate cancer stem cells and a proportional effect on midkine levels. AB - Prostate cancer (PCa) is the second most frequent type of cancer in men worldwide and the levels of differentiation growth factor midkine (MK) are increased in PCa. Cancer and/or the treatment process itself may lead to psychiatric disorders. Lithium chloride (LiCl) has anti-manic properties and has been used in cancer therapy; however, it has a queried safety profile. In addition, cancer stem cells are responsible for the heterogeneous phenotype of tumor cells; they are involved in progression, metastasis, recurrence and therapy resistance in various cancer types. The aims of the present study were to investigate the effect of different concentrations of LiCl on PCa stem cells (whether a shift from tumorigenic to non-tumorigenic cells occurs) and to determine if these results can be explained through changes in MK levels. Monolayer and spheroid cultures of human prostate stem cells and non-stem cells were incubated with low (1, 10 uM) and high (100, 500 uM) concentrations of LiCl for 72 h. Cell proliferation, apoptotic indices, MK levels and ultrastructure were evaluated. Cells stimulated with low concentrations showed high proliferation, low apoptotic indices, high MK levels and more healthy ultrastructure. Opposite results were obtained at high concentrations. Furthermore, stem cells were more sensitive to stimulation and more resistant to inhibition than non-stem cells. LiCl exhibited concentration-dependent effects on stem cell and non-stem cell groups. MK levels were not involved in the biphasic effect of LiCl; however, they were proportionally affected. To the best of our knowledge, the present study was the first to show the effect of LiCl on PCa stem cells through MK. PMID- 27703534 TI - Patients' perception of differences in general practitioners' attitudes toward immigrants compared to the general population: Qualicopc Slovenia. AB - INTRODUCTION: Globally, the number of immigrants is rising every year, so that the number of immigrants worldwide is estimated at 200 million. In Slovenia, immigrants comprise 6.5% of the overall population. Immigrants bring along to a foreign country their cultural differences and these differences can affect immigrants' overall health status and lead to chronic health conditions. The aim of this study was to identify patients' perception of general practitioners' (GPs') attitudes toward immigrants in Slovenia. METHODS: This study was based on the Qualicopc questionnaire. We used the questions that targeted patients' experience with the appointment at their GP on the day that the study was carried out. RESULTS: There were no differences in GPs' accessibility based on groups included in our study (p>0.05). Compared to the non-immigrant population, first generation immigrants answered that their GPs were impolite (p=0.018) and that they did not take enough time for them (p=0.038). In addition, they also experienced more difficulties understanding their GP's instructions (p<0.001). Second-generation immigrants experienced more negative behaviour from GPs, and first-generation immigrants had more difficulties understanding GPs' instructions. CONCLUSION: There may be some differences in patients' perception of GPs' attitudes towards immigrants in comparison with the general Slovenian population. However, based on the perception of the immigrants that do benefit from the medical care it is not possible to judge the GPs' attitudes towards immigrants as worse compared to their attitude towards the non-immigrant population. Indeed, there may be other reasons why the patients answered the way they did. PMID- 27703535 TI - Cross-cultural adaptation and validation of the disease specific questionnaire OQLQ in Serbian patients with malocclusions. AB - INTRODUCTION: Dentofacial disorders may potentially significantly affect the quality of life. Objectives of this study were to validate translated and culturally adapted Orthognatic Quality of Life Questionnaire (OQLQ) on a cohort of Serbian patients with malocclusions. METHODS: The questionnaire was validated in 111 consecutive patients with malocclusions, seen between December 2014 and February 2015 at the Clinic of Orthodontics, Faculty of Dental Medicine, University of Belgrade. Clinical validity was assessed comparing the mean scores for the four subscales of the OQLQ and mean PAR pre-treatment score. In order to assess whether the allocation of items in the subscales corresponds to their distribution in the original questionnaire, an exploratory factor analysis (principal component analysis with varimax rotation) was conducted. RESULTS: The results of the internal consistency analysis demonstrated good relationships between the items; Cronbach's alpha coefficients for the four subscales were highly significant (p<0.001) (0.88-0.91). All items were significantly correlated between baseline and the retest (6 weeks after). The correlations between the PAR and all four domains of the OQLQ were all significant (p<0.01). The loading weights obtained in the exploratory factor analysis showed that this model revealed four factors with eigenvalue greater than 1, explaining the 64.0% of the cumulative variance. The majority of the items (86.4%) in the Serbian version of the OQLQ presented the highest loading weight in the subscales assigned by the OQLQ developer. CONCLUSIONS: The psychometric properties of the OQLQ (Serbian version) have exceptional internal consistency and reproducibility as an instrument for evaluation of dental malocclusions. Additionally, this questionnaire may be useful as a supplementary outcome measure in persons with malocclusions. PMID- 27703536 TI - Under-reporting of sexually transmitted infection with chlamydia trachomatis - a revision of surveillance system is required. AB - INTRODUCTION: To consider whether a revision of the national chlamydia surveillance system is needed, the objectives were to estimate the proportion of laboratory confirmed cases at the Institute of Microbiology and Immunology (IMI) not reported to the National Institute of Public Health (NIPH), and to assess the completeness of reporting for individual data items. METHODS: The dataset with information about the cases diagnosed at the IMI during 2007-2010, and the national chlamydia surveillance data at the NIPH, were linked using SOUNDEX code and the date of birth as unique identifier. The proportion of unreported cases was calculated. The proportions of records with missing data for individual variables were estimated for all reported cases during the same period. Chlamydia testing and reported rates for the period 2002-2010 were presented. RESULTS: Of 576 laboratory confirmed chlamydia cases at the IMI during 2007-2010, 201 were reported to the NIPH, corresponding to 65.1% of the overall underreporting (50.4% among dermatovenerologists, 90.1% among gynaecologist and 100% among other specialists). Item response was above 99% for demographic variables and from 69% to 81% for sexual behaviour variables. Higher testing rates corresponded to higher diagnosed rates. CONCLUSIONS: Surveillance data underestimated diagnosed chlamydia infection rates. Mandatory reporting of cases by laboratories with less variables, including unique identifier, gender, date of diagnosis, and reporting physician specialty, together with numbers of tests performed (for estimating testing and positivity rates) would simplify the surveillance system and eliminate underreporting of laboratory confirmed cases, while still providing necessary information for public health policies. PMID- 27703537 TI - Quality of care for patients with diabetes mellitus type 2 in 'model practices' in Slovenia - first results. AB - BACKGROUND: A new organisation at the primary level, called model practices, introduces a 0.5 full-time equivalent nurse practitioner as a regular member of the team. Nurse practitioners are in charge of registers of chronic patients, and implement an active approach into medical care. Selected quality indicators define the quality of management. The majority of studies confirm the effectiveness of the extended team in the quality of care, which is similar or improved when compared to care performed by the physician alone. The aim of the study is to compare the quality of management of patients with diabetes mellitus type 2 before and after the introduction of model practices. METHODS: A cohort retrospective study was based on medical records from three practices. Process quality indicators, such as regularity of HbA1c measurement, blood pressure measurement, foot exam, referral to eye exam, performance of yearly laboratory tests and HbA1c level before and after the introduction of model practices were compared. RESULTS: The final sample consisted of 132 patients, whose diabetes care was exclusively performed at the primary care level. The process of care has significantly improved after the delivery of model practices. The most outstanding is the increase of foot exam and HbA1c testing. We could not prove better glycaemic control (p>0.1). Nevertheless, the proposed benchmark for the suggested quality process and outcome indicators were mostly exceeded in this cohort. CONCLUSION: The introduction of a nurse into the team improves the process quality of care. Benchmarks for quality indicators are obtainable. Better outcomes of care need further confirmation. PMID- 27703538 TI - Knowledge of health principles among professionals in Slovenian kindergartens. AB - OBJECTIVES: Preschool children have significant health issues. From the relevant legislation and regulations, it can be seen that kindergarten teachers (KTs) and kindergarten teacher assistants (KTAs) are expected to be familiarwith the basic hygienic measures and steps for preventing injuries and illnesses, to recognize infectious diseases, and to know how to give the first aid. To gain these skills, a continuous life-long learning is necessary, because the characteristics of diseases are changing. Study design: original research. METHODS: 45 kindergartens in Slovenia were randomly selected and a questionnaire with 17 questions on health themes was sent. An analysis was performed via SPSS 17.0, using descriptive methods and nonparametric chi2 tests. RESULTS: There were 774 participants, of whom 56% were KTs and 44% KTAs. The share of KTs and KTAs who consider their knowledge of health principles to be very good or excellent is 67%. Their estimation of first aid knowledge is lower. They are also well aware of the importance of health knowledge in their work; a total of 87% strongly agree with this. The results also show that they are familiar with hygiene principles. The chi2 test showed there are certain statistically characteristic connections between the age of teachers and their assistants, occupation and work experiences. CONCLUSIONS: Because children are a particularly vulnerable group, teachers can encounter injuries and sudden illnesses at their work. Supplementary education is necessary among skilled workers in educational institutions, including kindergartens. PMID- 27703540 TI - Prevalence of problematic internet use in Slovenia. AB - BACKGROUND: Internet use is an integral part of our everyday activities; however, Internet use may become problematic and harmful in a minority of cases. The majority of reported prevalence rates of problematic Internet use refer to adolescent samples, whereas epidemiological studies on representative adult populations are lacking. This study aimed to reveal the prevalence and characteristics of problematic Internet use in Slovenia. METHODS: Problematic Internet Use Questionnaire (PIUQ) was included in European Health Interview Study (EHIS) on representative Slovenian sample. The frequency of Internet use and problematic Internet use were both assessed. RESULTS: 59.9% of Slovenian adult population uses the Internet daily, and 3.1% are at risk of becoming problematic Internet users, 11% in the age group from 20 to 24 years. Those being at risk for becoming problematic Internet users are younger (mean age 31.3 vs. 48.3 for non problematic users), more likely to be males (3.6% of males, whereas 2.6% of females are affected), students (12.0%), unemployed (6.3%) or unable to work (8.7%), single (6.5%), with high education (4.5%). Regression analysis revealed that the strongest predictor of being at risk for problematic Internet use is age (beta=-0.338, p<0.001); followed by high educational level (beta=0.145; p<0.001) and student status (beta=0.136; p<0.001). CONCLUSION: 3.1% of Slovenian adult population are at risk of becoming problematic Internet users, whereas 3 out of 20 Slovenian adolescents aged from 18 to 19 years are at risk (14.6%). Prevention programs and treatment for those affected are paramount, especially for the young generation. PMID- 27703539 TI - Analysis of expired medications in Serbian households. AB - INTRODUCTION: An ongoing issue of expired medications accumulating in some households is a universal problem around the world. The aim of the study was to investigate the extent and structure of expired medications in Serbian households, and to determine which therapeutic groups generated the most waste. METHODS: This was an observational, cross-sectional study conducted in households in the city of Novi Sad, Serbia. The study had been performed over 8 month period (December 2011 - July 2012) and it consisted of personal insights into the medication inventory in households. RESULTS: Of 1008 families, 383 agreed to participate and complete the questionnaire (38.3% response rate). In almost a half of households (44.4%), expired medications were maintained. The amount of expired medications was 402 items, corresponding to 9.2% of total medications presented in surveyed households. The majority of expired medications (64.7%) was in solid dosage (tablets, capsules, granules, lozenges), following semisolid (ointments, creams, gel, suppositories) and liquid dosage forms (drops, syrups). Expired medications in the households belonged mostly to 3 categories: antimicrobials for systemic use (16.7%), dermatological preparation (15.9%) and medications for alimentary tract and metabolism (14.2%). CONCLUSIONS: This study revealed that there were relatively large quantities of expired medications in Serbian households, with a high prevalence of antibiotics for systemic use, anti inflammatory and antirheumatic products, and medications for alimentary tract and metabolism. PMID- 27703541 TI - Prevalence of violence towards nursing staff in Slovenian nursing homes. AB - INTRODUCTION: The purpose of this research was to identify the prevalence of violence towards nursing staff in Slovenian nursing homes. METHODS: For the purpose of this study, a non-experimental sampling method was employed, using a structured questionnaire as a data collection instrument (n=527). The contents of the questionnaire proved valid and reliable, with a high enough degree of internal consistency (Cronbach Alpha minimum 0.82). RESULTS: The nursing staffs working in nursing homes for senior citizens are at high risk of violence. In the last year, the employees were most often faced with verbal violence (71.7%), physical violence (63.8%) and sexual violence (35.5%). 35.5% of employees suffered injuries at their working place. During aggressive outbursts of nursing home residents, employees particularly experience vulnerability, fear and insecurity. CONCLUSION: There is a need for a comprehensive approach to tackle workplace violence. Some psychiatric health care facilities have already introduced certain measures in this field, and reduction of workplace violence proves that it is possible to reduce aggressive outbursts of patients. After conducting further quantitative research, which would expose detailed characteristics and the background of such violence, it would be sensible to develop similar measures in the field of health care in nursing homes. PMID- 27703543 TI - Health care reforms. AB - In large systems, such as health care, reforms are underway constantly. The article presents a definition of health care reform and factors that influence its success. The factors being discussed range from knowledgeable personnel, the role of involvement of international experts and all stakeholders in the country, the importance of electoral mandate and governmental support, leadership and clear and transparent communication. The goals set need to be clear, and it is helpful to have good data and analytical support in the process. Despite all debates and experiences, it is impossible to clearly define the best approach to tackle health care reform due to a different configuration of governance structure, political will and state of the economy in a country. PMID- 27703542 TI - Primary care for the Roma in Europe: Position paper of the European forum for primary care. AB - Roma populations' low health status and limited access to health services, including primary care, has been documented in many European countries, and warrants specific health policies and practices. A variety of experiences shows how primary care can adjust its practices to reduce the barriers to primary care for Roma populations. At local level, establishing collaboration with Roma organisations helps primary care to improve mutual relations and quality of care. Mediation has proved to be an effective tool. Skills training of primary care practitioners may enhance their individual competences. Research and international sharing of experiences are further tools to improve primary care for the Roma people. PMID- 27703544 TI - Zika: an old virus with a new face. AB - Zika virus is a mosquito-borne flavivirus that represents a public health emergency at the ongoing epidemic. This obscure virus was limited to sporadic cases in Africa and Asia, until the emergence of Zika virus in Brazil in 2015, when it rapidly spread throughout the Americas. Most Zika virus infections are subclinical or characterized by mild febrile illness. However, neurological complications, including Guillain-Barre syndrome in adults, and congenital anomalies, including microcephaly in babies born to infected mothers, raised a grave concern. Currently, there is no specific antiviral treatment or vaccine available for Zika virus infection. Thus, international public health response is primarily focused on preventing infection, particularly in pregnant women, and on providing up-to-date recommendations to reduce the risk of non-vector transmission of Zika virus. PMID- 27703546 TI - The prevalence of and risk factors for healthcare-associated infections in Slovenia: results of the second national survey. AB - INTRODUCTION: In the second Slovenian national healthcare-associated infections (HAIs) prevalence survey, conducted within the European point prevalence survey of HAIs and antimicrobial use in acute-care hospitals, we estimated the prevalence of all types of HAIs and identified risk factors. METHODS: Patients from acute-care hospitals were enrolled into a one-day cross-sectional study in October 2011. Descriptive analyses were performed to describe the characteristics of patients, their exposure to invasive procedures and the prevalence of different types of HAIs. Univariate and multivariate analyses of association of having at least one HAI with possible risk factors were performed to identify risk factors. RESULTS: Among 5628 patients, 3.8% had at least one HAI and additional 2.6% were still being treated for HAIs on the day of the survey; the prevalence of HAIs was 6.4%. The prevalence of urinary tract infections was the highest (1.4%), followed by pneumoniae (1.3%) and surgical site infections (1.2%). In intensive care units (ICUs), the prevalence of patients with at least one HAI was 35.7%. Risk factors for HAIs included central vascular catheter (adjusted odds ratio (aOR) 4.0; 95% confidence intervals (CI): 2.9-5.7), peripheral vascular catheter (aOR 2.0; 95% CI: 1.5-2.6), intubation (aOR 2.3; 95% CI: 1.4-3.5) and rapidly fatal underlying condition (aOR 2.1; 95% CI: 1.4-3.3). CONCLUSIONS: The prevalence of HAIs in Slovenian acute-care hospitals in 2011 was substantial, especially in ICUs. HAIs prevention and control is an important public health priority. National surveillance of HAIs in ICUs should be developed to support evidence-based prevention and control. PMID- 27703545 TI - The role of non-governmental organizations in the mental health area: differences in understanding. AB - INTRODUCTION: The contribution's aim is highlighting the differences in understanding non-governmental organizations' (NGOs) role in the mental health area within the public support network for patients with mental health problems from various viewpoints, in order to achieve progress in supporting patients with mental health problems in local communities. METHODS: Qualitative data gathered as a part of a cross-sectional study of NGOs in the support network for patients with mental health problems in two Slovenian health regions (56 local communities), carried out in 2013 and 2014, were used. Qualitative analysis of interviews, focus groups and answers to an open survey question was performed. RESULTS: There are differences in understanding NGOs' role in the support network for patients with mental health problems, which stem from the roles of stakeholders (local community officials, experts, care providers, and patients) within this system and their experience. DISCUSSION AND CONCLUSION: The actual differences need to be addressed and overcome in order to provide integrated community care. The importance of knowing the current state of NGOs in their life cycle and the socio-chronological context of the local community support network is evident. PMID- 27703547 TI - Sensitivity and specificity of the method used for ascertainment of healthcare associated infections in the second Slovenian national prevalence survey. AB - INTRODUCTION: The second Slovenian national healthcare-associated infections (HAIs) prevalence survey (SNHPS) was conducted in acute-care hospitals in 2011. The objective was to assess the sensitivity and specificity of the method used for the ascertainment of six types of HAIs (bloodstream infections, catheter associated infections, lower respiratory tract infections, pneumoniae, surgical site infections, and urinary tract infections) in the University Medical Centre Ljubljana (UMCL). METHODS: A cross-sectional study was conducted in patients surveyed in the SNHPS in the UMCL using a retrospective medical chart review (RMCR) and European HAIs surveillance definitions. Sensitivity and specificity of the method used in the SNHPS using RMCR as a reference was computed for ascertainment of patients with any of the six selected types of HAIs and for individual types of HAIs. Agreement between the SNHPS and RMCR results was analyzed using Cohen's kappa coefficient. RESULTS: 1474 of 1742 (84.6%) patients surveyed in the SNHPS were included in RMCR. The sensitivity of the SNHPS method for detecting any of six HAIs was 90% (95% confidence interval (CI): 81%-95%) and specificity 99% (95% CI: 98%-99%). The sensitivity by type of HAI ranged from 63% (lower respiratory tract infections) to 92% (bloodstream infections). Specificity was at least 99% for all types of HAIs. Agreement between the two data collection approaches for HAIs overall was very good (kappa=0.83). CONCLUSIONS: The overall sensitivity of SNHPS collection method for ascertaining HAIs overall was high and the specificity was very high. This suggests that the estimated prevalence of HAIs in the SNHPS was credible. PMID- 27703548 TI - A methodological approach to the analysis of egocentric social networks in public health research: a practical example. AB - INTRODUCTION: Research on social networks in public health focuses on how social structures and relationships influence health and health-related behaviour. While the sociocentric approach is used to study complete social networks, the egocentric approach is gaining popularity because of its focus on individuals, groups and communities. METHODS: One of the participants of the healthy lifestyle health education workshop 'I'm moving', included in the study of social support for exercise was randomly selected. The participant was denoted as the ego and members of her/his social network as the alteri. Data were collected by personal interviews using a self-made questionnaire. Numerical methods and computer programmes for the analysis of social networks were used for the demonstration of analysis. RESULTS: The size, composition and structure of the egocentric social network were obtained by a numerical analysis. The analysis of composition included homophily and homogeneity. Moreover, the analysis of the structure included the degree of the egocentric network, the strength of the ego-alter ties and the average strength of ties. Visualisation of the network was performed by three freely available computer programmes, namely: Egonet.QF, E-net and Pajek. The computer programmes were described and compared by their usefulness. CONCLUSION: Both numerical analysis and visualisation have their benefits. The decision what approach to use is depending on the purpose of the social network analysis. While the numerical analysis can be used in large-scale population based studies, visualisation of personal networks can help health professionals at creating, performing and evaluation of preventive programmes, especially if focused on behaviour change. PMID- 27703549 TI - Neck Circumference in Overweight/Obese Subjects who Visited the Binjai Supermall in Indonesia. AB - BACKGROUND: Neck circumference (NC) is a simple screening measure for identifying overweight and obesity, it reflects upper-body fat distribution and central obesity. AIM: To determine whether a single measure of NC might be used to identify overweight/obesity. MATERIAL AND METHODS: An observational, analytical, cross-sectional study was done. The subjects consisted of all consecutive subjects who visited Binjai Supermall (North Sumatera Province, Indonesia) between 23rd and 29th September 2015 and agreed to participate in the study. NC, weight, height, body mass index (BMI), and waist circumference (WC) were measured. Overweight and obesity were defined as BMIs of 23.0-24.9 and >= 25 kg/m2, respectively. RESULTS: In total, 1554 subjects participated. Of these, 1238 (79.7%) were overweight/obese. NC correlated significantly with weight, height, BMI, and WC. Receiver operating characteristic (ROC) analysis showed that for all men and women, the area under the curve of overweight/obesity for NC was 0.83 and 0.79, respectively. The best NC cutoff points for males and females that indicated overweight/obesity were >= 37 cm (sensitivity, 78.3% and specificity, 75.5%) and >= 33.5 cm (sensitivity, 76.6% and specificity, 66.7%), respectively. CONCLUSION: The NC cutoffs that were identified may be useful for screening for overweight/obesity and related co-morbidities. PMID- 27703550 TI - Serum Interleukin-18 and Its Gene Haplotypes Profile as Predictors in Patients with Diabetic Nephropathy. AB - BACKGROUND: Diabetic nephropathy (DN) is known as an acute microvascular complexity as a subsequence progression in diabetes mellitus type 1 and 2. Many evidence pointed that the proinflammatory cytokine Interleukin (IL)-18 might be involved in the pathogenesis of DN. AIM: The current study aimed to evaluate the association of serum IL-18 and its promoter gene polymorphisms with diabetic nephropathy. METHODS: This study included 62 diabetic nephropathy patients (DN group) compared to 52 diabetes mellitus patients (DM group). The two groups were subjected to anthropometry assessment, molecular studies including SNP genotyping by RFLP and finally statistical analysis. RESULTS: The assessment of the serum IL 18 level and the frequencies of its allele and haplotype: -137G/C, -607C/A and 656G/T among the DN and DM subjects revealed that -137G allele has significant variation between DN and DM subjects (about 80.8%, P = 0.05) but, no significant variation in -607 or -656 alleles IL-18 gene promoter. CONCLUSION: These data confirm the impact of high serum IL-18 and the haplotype of the polymorphism located in the promoter region of the IL-18 gene with the DN. PMID- 27703552 TI - Curative Effect of Aqueous Leaf Extract of Crinum Giganteum on NMDA-Receptor Antagonist-Induced Schizophrenic Wistar Rat Model. AB - AIM: This study evaluated the curative potential of Crinum giganteum in the treatment of schizophrenia using an NMDA-receptor antagonist-induced schizophrenic Wistar rat model. METHODS: Twenty-five adult Wistar rats of both sexes of average weights 180 g were divided into two groups: control and schizophrenic rat models. The controls received 0.1 ml of 0. 9% saline, while schizophrenia was induced in models using 25 mg/kg of ketamine hydrochloride (i.p.) for 7 days. On the 8 day models were divided into group's k1, k2, k3 and k4 of 5 rats each. K1 and the controls were sacrificed then, groups k2 and k3 were treated with 5 mg/kg and 10 mg/kg aqueous leaf extract of Crinum giganteum while, k4 (standard) received 25 mg/kg of chlorpromazine orally for 28 days. Amygdala were harvested, processed and stained with Haematoxylin and Eosin (H &E) stain, Neuron-specific enolase (NSE) marker was also used to monitor the curative effect on the amygdala. RESULTS: Degenerative changes and increased NSE immunoreactivity were observed in the untreated models. Extract-treated models showed normal amygdala and negative NSE immunoreactivity while chlorpromazine treated models revealed decreased NSE immunoreactivity. CONCLUSION: Crinum giganteum extracts exhibits better curative effect than the standard antipsychotic agent. PMID- 27703553 TI - Influence of Parental and Some Demographic Characteristics on Overweight/Obesity Status among a Sample of Egyptian Children. AB - BACKGROUND: Overweight/obesity is a multi-factorial problem, which results from rapidly changing social, economic, and physical environments that have led to an energy imbalance. AIM: To identify the association between childhood overweight/obesity and some socio-demographic risk factors, as parental age, body mass index (BMI), education and occupation, family size and residence (urban/rural). SUBJECTS AND METHODS: Cross-sectional study included 154 children of both sexes; aged 5-18 years; with their parents; one of them was working at the National Research Centre and from their relatives and neighbours. Data was collected about the child birth weight, family size, parental ages, education, occupation and place of residence. Anthropometric measurements including weight, height, and body mass index (BMI) of children and their parents were conducted. RESULTS: Obesity was detected among 19.5% of children (BMI > 95th percentile), 75.3% of their mothers and 49.6% of their fathers (BMI > 30 Kg/m^2). While overweight was present in 11.0% of the children (BMI > 85th- <95 percentile), 16.9% of their mothers and 36.5% of their fathers (BMI > 25-29.9 Kg/m^2). Child obesity was more prominent in urban than rural areas (21.3% versus 12.5%) and among housewives (22.8%) than among working mothers (16%, p < 0.016). Child overweight was more common in rural than urban areas (12.5% versus 10.7%) and among children with high father education (20%). Child BMI had significant positive correlations only with the child age, parental ages and BMIs, and family size. In spite of that, parental BMIs had significant positive correlations with each other and with family size, and significant negative correlations with maternal education and occupation and paternal education. CONCLUSION: Childhood obesity and overweight were more prominent in urban than rural areas, among children with non-working housewives mothers and highly educated fathers (college or above). Parental education and occupation had an indirect significant effect on child BMI through their significant effect on parental BMIs. PMID- 27703551 TI - Protective Effects of Vasodilatory Betaeta-Blockers Carvedilol and Nebivolol against Glycerol Model of Rhabdomyolysis-Induced Acute Renal Failure in Rats. AB - BACKGROUND: Rhabdomyolysis (RM)-induced acute renal failure (ARF) accounts for about 10-40% of all cases of ARF. AIM: The present study investigated the possible protective effect of two nitric oxides (NO)-releasing third generation beta-blockers, carvedilol (Carv) and nebivolol (Nebi), against RM-mimicking glycerol (Gly)-induced ARF in rats. MATERIAL AND METHODS: After 24 h dehydration, rats received a single dose of 50% Gly (8 ml/kg, im). They were treated with vehicle, Carv (2.5 mg/kg/day, po) or Nebi (10 mg/kg, po) for 3 successive days starting from an hour prior to Gly injection. Evaluation of blood pressure and locomotor activity was performed during the experiment. 72 h following Gly administration, total protein in the urine, serum levels of creatinine, blood urea nitrogen, sodium and potassium as well as the renal contents of malondialdehyde, reduced glutathione and NO were assessed, together with a histopathological examination of renal tissues. RESULTS: Carv and Nebi attenuated Gly-induced renal dysfunction and histopathological alterations. They decreased the Gly-induced oxidative stress and increased renal NO concentration. Restoration of normal blood pressure and improvement of locomotor activity were also observed. CONCLUSION: The results clearly demonstrate protective effects of Carv and Nebi against renal damage involved in RM-induced ARF and suggest a role of their antioxidant and NO-releasing properties. PMID- 27703554 TI - New Era for Usage of Serum Liver Enzymes as A Promising Horizon for the Prediction of Non-Alcoholic Fatty Liver Disease. AB - BACKGROUND: Liver histology remains the gold standard for assessing non-alcoholic fatty liver disease (NAFLD). Noninvasive serological markers and radiological methods have been developed to evaluate steatosis to avoid biopsy. AIM: To put cutoff value for liver enzymes that could predict non-alcoholic steatohepatitis (NASH). PATIENTS AND METHODS: This study was conducted on 54 patients (with NAFLD diagnosed by the US). Patients were subjected to history, physical, anthropometric measurements, investigations including liver enzymes, abdominal US, and liver biopsy. According to biopsy results, patients were subdivided according to NASH development. Also, biopsy results were correlated to the levels of liver enzymes. RESULTS: Forty-seven patients who were suspected to have NAFLD by sonar were confirmed by biopsy. There was a significant correlation between steatosis degree in biopsy and sonar. Correlation study between steatosis in biopsy and ALT level showed highly significant positive correlation. Correlation study between steatosis in biopsy on one side & AST and GGT on the other side showed significant positive correlation. Cutoff value for detection of NASH using ALT & AST & and GGT were 50.5, 56, 60.5 respectively with sensitivity = 95.5, 90.5, 86.4 % and specificity = 93.8, 100, 87.5%. CONCLUSION: Cut off values of liver enzymes can be combined with abdominal sonar to predict NASH. PMID- 27703555 TI - Dietary Behaviour Pattern and Physical Activity in Overweight and Obese Egyptian Mothers: Relationships with Their Children's Body Mass Index. AB - BACKGROUND: Obesity and related morbidity increase in Egyptian women and their children. A better understanding of dietary and activity patterns is needed to reduce obesity prevalence. AIM: The present study aimed to assess dietary patterns and physical activity in Egyptian overweight and obese mothers and to explore its relationships with their children's body mass index (BMI). SUBJECTS AND METHODS: This descriptive case-control study was conducted at the National Research Center. The study included a sample of 64 overweight and obese mothers and 75 children, compared with apparently healthy non-obese mothers and their children of matched age and social class. Tested questionnaires were used to collect information of the studied subjects. RESULTS: A statistically significantly higher incidence of unemployment, large family size was observed in overweight & obese women compared to controls (P < 0.05). Those women who consumed vegetables more than 3 times a week were less likely to be overweight or obese (P < 0.05). No significant association were detected between mothers' physical activity, dietary behaviour variables and children's BMI except for consuming beverages with added sugar (95%CI = 0.074-0.985, P<0.05). CONCLUSION: Improper dietary patterns, nonworking mothers and big family size are associated with obesity among Egyptian women. Emphasis should be given to increasing physical activity and encourage healthier diets among Egyptian mothers and their children. PMID- 27703556 TI - Serum IL-10, MMP-7, MMP-9 Levels in Helicobacter pylori Infection and Correlation with Degree of Gastritis. AB - AIM: Helicobacter pylori causes gastric mucosal inflammation and immune reaction. However, the increase of IL-10, MMP-7, and MMP-7 levels in the serum is still controversial. The objective of this study was to investigate the serum levels of IL-10, MMP-7 & MMP-9 in gastritis patients with H. pylori infection. MATERIALS AND METHODS: A cross-sectional study was done on seventy gastritis patients that consecutive admitted to endoscopy units. The diagnosis of gastritis was made based on histopathology and diagnosis of H. pylori infection was based on rapid urease test. Serum samples were obtained to determine to circulate IL-10, MMP-7, and MMP-9 level. Univariate and bivariate analysis were done by SPSS version 22. RESULTS: Forthy percentages of the patients were infected with H. pylori. The IL 10 level was significantly higher in H. pylori-infected patients compared to non infected patients. However, there were no differences between serum levels of MMP 7 and MMP-9 in infected and non-infected H. pylori patients. CONCLUSIONS: The immune response to H. pylori promotes systemic inflammation, which was reflected by the increased levels of serum IL-10. However, there were no significant differences in MMP-7 and MMP-9 serum levels between positive and negative infected H. pylori patients. PMID- 27703557 TI - Immunomodulatory Effect of H. Pylori CagA Genotype and Gastric Hormones On Gastric Versus Inflammatory Cells Fas Gene Expression in Iraqi Patients with Gastroduodenal Disorders. AB - AIM: To evaluate the Immunomodulatory effects of CagA expression; pepsinogen I, II & gastrin-17 on PMNs and lymphocytes Fas expression in inflammatory and gastric cells; demographic distribution of Fas molecule in gastric tissue and inflammatory cells. METHODS: Gastroduodenal biopsies were taken from 80 patients for histopathology and H. pylori diagnosis. Serum samples were used for evaluation of pepsinogen I (PGI); (PGII); gastrin-17 (G-17). RESULTS: Significant difference (p < 0.001) in lymphocytes & PMNs Fas expression; epithelial & lamina propria Fas localization among H. pylori associated gastric disorders. No correlation between grade of lymphocytes & PMNs Fas expression in gastric epithelia; lamina propria and types of gastric disorder. Significant difference (p < 0.001) in total gastric Fas expression, epithelial Fas; lamina propria and gastric gland Fas expression according to CagA, PGI; PGII; PGI/PGII; Gastrin-17. Total gastric Fas expression has significant correlation with CagA, PGII levels. Gastric epithelial and gastric lamina propria Fas expression have significant correlation with CagA, PGI; PGII levels. Significant difference (p < 0.001) was found in lymphocytes & PMNs Fas expression; epithelial & lamina propria localization of lymphocytes & PMNs Fas expression according to CagA, PGI; PGII; PGI/PGII; Gastrin-17. Lymphocytes Fas expression have correlation with PGI, PGII, PGI/PGII. PMNs Fas expression have correlation with PGI, PGII. CONCLUSION: Fas gene expression and localization on gastric and inflammatory cells affected directly by H. pylori CagA and indirectly by gastric hormones. This contributes to progression of various gastric disorders according to severity of CagA induced gastric pathology and gastric hormones disturbance throughout the course of infection and disease. PMID- 27703558 TI - Diagnostic Accuracy of Acoustic Radiation Force Impulse (ARFI) in Diagnosis of Liver Fibrosis among Egyptian Patients with Chronic HCV Infection. AB - BACKGROUND: Acoustic radiation force impulse (ARFI) evaluates liver stiffness non invasively and was invented recently. This technique can easily and accurately assess the degree of liver fibrosis in clinical practice. AIM: The aim of this study was to detect the diagnostic performance of ARFI elastography in the staging of fibrosis in some Egyptian patients with chronic HCV infection. PATIENTS AND METHODS: One hundred ninety patients with chronic HCV infection; 142 men and 48 women were enrolled in the study. They underwent liver biopsy examination for liver fibrosis detection. All demographic; clinical and biochemical data were recoded. ARFI examination was done for all subjects to detect liver stiffness measurement in relation to liver fibrosis detected by pathological examination of liver biopsies. RESULTS: Medians of liver stiffness measurement by shear wave velocity showed a significant increase as a grade of liver fibrosis increases (p <= 0.0001, highly significant). Liver stiffness was directly correlated to age, AST; ALT; INR and liver steatosis (p values were: 0.009; 0.0001; 0.013; 0.006 and 0.04 respectively, significant). On the other hand, liver stiffness was inversely correlated to albumin; prothrombin concentration and platelets (p values were: 0.0001; 0.001, and 0.0001, respectively, significant). We found that shear wave velocity can predict F1; F2; F3 and F4 at cut-off values: 1.22; 1.32; 1.44 and 1.8 respectively. CONCLUSION: ARFI is a diagnostic noninvasive promising technique for liver fibrosis diagnosis among Egyptian patients with chronic HCV infection. PMID- 27703559 TI - Risk Factors of End Stage Renal Disease in Peshawar, Pakistan: Odds Ratio Analysis. AB - AIM: The basic aim of this study was to discover the association of End Stage Renal Disease (ESRD) with various risk factors. End Stage Renal Failure is the last stage of the chronic renal failure in which kidneys become completely fail to function. MATERIALS AND METHODS: The data were collected from the patients of renal diseases from three major hospitals in Peshawar, Pakistan. Odds ratio analysis was performed to examine the relationship of ESRD (a binary response variable) with various risk factors: Gender, Diabetic, Hypertension, Glomerulonephritis, Obstructive Nephropathy, Polycystic kidney disease, Myeloma, SLE Nephritis, Heredity, Hepatitis, Excess use of Drugs, heart problem and Anemia. RESULTS: Using odds ratio analysis, the authors found that the ESRD in diabetic patients was 11.04 times more than non-diabetic patients and the ESRD were 7.29 times less in non-hypertensive patients as compared to hypertensive patients. Similarly, glomerulonephritis patients had 3.115 times more risk of having ESRD than non-glomerulonephritis. Other risk factors may also, to some extent, were causes of ESRD but turned out insignificant due to stochastic sample. CONCLUSION: The authors concluded that there is a strong association between ESRD and three risk factors, namely diabetes, hypertension and glomerulonephritis. PMID- 27703560 TI - Patients with Schizophrenia and Social Contacts. AB - BACKGROUND: Patients with schizophrenia have severe problems with personal and social relations which affect their quality of life. AIM: The aim of the paper was to monitor personal and social relations in patients with schizophrenia and to find out the differences regarding socio-demographic characteristics and ambulatory and day hospital treatment. MATERIAL AND METHODS: The investigation included 120 subjects each with diagnosis F20 according to ICD 10 criteria; divided into two groups of 60 patients regarding their actual treatment (the first group received ambulatory care whereas those from the second group had a day hospital treatment). Patients were of different age and gender, receiving regular antipsychotic therapy. They were included in individual and group psychosocial therapeutic procedures during the day hospital treatment. The investigation utilised the following diagnostic instruments: standardised clinical interview and Personal and social performance scale (PSP scale), a non standardized questionnaire of socio-demographic data, family support and existence of mental disorder in other family members. RESULTS: The results have shown better personal and social functioning in patients who had family support, in those who are employed, in those with no mental disorder in other family members and in patients on day hospital treatment against patients receiving ambulatory care. CONCLUSION: Day hospital treatment, family support and social support improve the ability for personal and social contacts of patients with schizophrenia. PMID- 27703561 TI - Ketamine Sedation in Gastrointestinal Endoscopy in Children. AB - BACKGROUND: Moderate sedation for gastrointestinal endoscopy has traditionally been provided by the endoscopist. Controversy has ensued over safe and efficient sedation practice as endoscopy has increased in numbers and complexity. AIM: To evaluate the safety of ketamine sedation given by non-anesthesiologist during gastrointestinal endoscopy in children. METHODS: A prospective study of 100 paediatric patients with gastrointestinal symptoms who were a candidate for upper or lower gastrointestinal endoscopy in paediatric endoscopy unit at Abo El-Reesh Paediatric Hospital, Cairo University. All children were > 2 years old and weighed > 6 kg. The analysis was performed in terms of sedation-related complications. RESULTS: A total 100 paediatric patients including 53 males and 47 females with mean age of 5.04 years were involved in the study. All children were medicated with ketamine with a mean dose of 3.77mg/kg. No complications occurred in 87% of cases. Desaturation occurred in 13% of the cases and was reversible by supplemental nasal oxygen. Desaturation was more frequent during Upper GI Endoscopy and with the intramuscular route (p value=0.049). No apnea, bradycardia, arrest or emergence reactions were recorded. CONCLUSION: Ketamine sedation found to be safe for paediatric gastrointestinal endoscopy in Egyptian children without co-morbidities. Transient Hypoxia (13%) may occur but easily reversed by nasal oxygen therapy. PMID- 27703562 TI - Justification for Rhinoseptoplasty in Children - Our 10 Years Overview. AB - BACKGROUND: Nasal septal surgery and rhinoplasty are controversial in children. Traditionally, an attitude of restraint has been employed by most surgeons till an empirical age of 16 to 18 years. This is to avoid the possible adverse effects that the growth spurts may have on the nose and midface region. AIM: The aim of this paper was to present the results of rhinoplasty in children in order to restore the anatomy and function or to promote normal development and outgrowth of the nose. MATERIAL AND METHODS: Ninety seven children aged 6-14, with severe nose deformities and breathing problems through the nose, were admitted for septo/rhinoplasty at the University Clinic for Ear, Nose and Throat, Faculty of Medicine, Ss Cyril and Methodius University of Skopje, Republic of Macedonia. At our Clinic, they have been observed and photographed (with parent permission) in the period of 10 years (2006-2016). The most frequent cause of these deformities was the nasal trauma in early childhood which was ignored or untreated. All of them rhino/septoplasty were indicated in accordance with the above-mentioned recommendations for rhino/septoplasty in early childhood and in adolescents. RESULTS: In 51 children and adolescents septoplasty were prepared. Mostly there was a group of younger children age from 6-10 (68%) and adolescents (32%). In the other 31 children and adolescents, septorhinoplasty was prepared. Mostly there were children older than 12 years old and adolescents (70%). Only 30% were younger than 12 years, of course with severe nasal breathing problems, nasal septal deformities and deformities of the nasal pyramid. CONCLUSION: The growth centres of the nose have to be avoided if possible; long-term nasal issues will theoretically be minimised. If the surgeon replaces it, the cartilage of the nose becomes straighter but still intact. PMID- 27703563 TI - Automated Versus Manual Blood Pressure Measurement: A Randomized Crossover Trial in the Emergency Department of a Tertiary Care Hospital in Karachi, Pakistan: Are Third World Countries Ready for the Change? AB - BACKGROUND: Hypertension has proven to be a strong liability with 13.5% of all mortality worldwide being attributed to elevated blood pressures in 2001. An accurate blood pressure measurement lies at the crux of an appropriate diagnosis. Despite the mercury sphygmomanometer being the gold standard, the ongoing deliberation as to whether mercury sphygmomanometers should be replaced with the automated oscillometric devices stems from the risk mercury poses to the environment. AIM: This study was performed to check the validity of automated oscillometric blood pressure measurements as compared to the manual blood pressure measurements in Karachi, Pakistan. MATERIAL AND METHODS: Blood pressure was recorded in 200 individuals aged 15 and above using both, an automated oscillometric blood pressure device (Dinamap Procare 100) and a manual mercury sphygmomanometer concomitantly. Two nurses were assigned to each patient and the device, arm for taking the reading and nurses were randomly determined. SPSS version 20 was used for analysis. Mean and standard deviation of the systolic and diastolic measurements from each modality were compared to each other and P values of 0.05 or less were considered to be significant. Validation criteria of British Hypertension Society (BHS) and the US Association for the Advancement of Medical Instrumentation (AAMI) were used. RESULTS: Two hundred patients were included. The mean of the difference of systolic was 8.54 +/- 9.38 while the mean of the difference of diastolic was 4.21 +/- 7.88. Patients were further divided into three groups of different systolic blood pressure <= 120, > 120 to = 150 and > 150, their means were 6.27 +/- 8.39 (p-value 0.175), 8.91 +/- 8.96 (p-value 0.004) and 10.98 +/- 10.49 (p-value 0.001) respectively. In our study 89 patients were previously diagnosed with hypertension; their difference of mean systolic was 9.43 +/- 9.89 (p-value 0.000) and difference of mean diastolic was 4.26 +/- 7.35 (p-value 0.000). CONCLUSIONS: Systolic readings from a previously validated device are not reliable when used in the ER and they show a higher degree of incongruency and inaccuracy when they are used outside validation settings. Also, readings from the right arm tend to be more precise. PMID- 27703564 TI - Role and Importance of Chlamydia Trachomatis in Pregnant Patients. AB - AIM: The aim of this study was to assess the prevalence of chlamydial infection among pregnant women and to determine the role of this infection in the fetus. MATERIAL AND METHODS: In the first phase of this study were reported 58 pregnant women with a positive test for active chlamydial infection by applying immunofluorescence. In the second phase of the study were reported pregnant with premature burst membranes (PBM), postnatal complications associated with chlamydial infection as puerperal endometritis, and newborns are monitored for low birth weight and growth retardation at birth. RESULTS: With a positive test are 58 patients in the first trimester or pregnancy registration in our consultation. After regimen with Sumamed (2 x 500 mg for three days and after 10 days again same scheme for them and their partner) at the beginning of the third trimester, the PCR test was made again. Of these, 5 were positive again, participants are between 20 and 30 years old. With premature rupture of OM are 20 patients. There was no increased incidence of premature births. Infants born to infected mothers have a higher risk of developing respiratory symptoms in the first 60 days of life. 3 of them have low for his age bodyweight. CONCLUSIONS: The scarcity of data on manifestations of chlamydial infection during pregnancy and neonatal outcomes justifies this study. Early diagnosis for registration of pregnancy and timely treatment of chlamydial infection as well as scrutinising the infection during the third trimester of pregnancy can prevent infection of the newborn. Therefore, preventive examinations should be considered as a priority for early detection of asymptomatic chlamydial infection in the conduct of antenatal care. PMID- 27703565 TI - The Impact of the Nasal Trauma in Childhood on the Development of the Nose in Future. AB - AIM: To prevent and to treat nasal trauma in children properly, because it can lead to displacement or depression of the nasal bones or septum. Second, our aim was, for the patient to recognise and create a mature decision for eventual nose changes which will be made with the operative intervention or they are not mature enough and the decisions were made by their parents. MATERIAL AND METHODS: Our retrospective study was made at University Clinic for Ear, Nose and Throat, Faculty of Medicine, Ss Cyril and Methodius University of Skopje in the period of 6 years (2005-2016). Seventy-three patients were admitted with recent or previous nasal trauma or nasal deformity. The first group of 32 were children and adolescents from 6-14 years old who were admitted to our hospital because of recent nasal trauma. The second group of 41 children and adolescents from 6-14 years old were admitted to our hospital because of previous nasal trauma, which was not treated on time, or it was not treated properly. They were admitted to our clinic for surgical intervention septo/rhinoplasty. The second group of patients fills the brief psychological questioner prepared by Clinical psychiatrist from University Clinic of Psychiatry, in Skopje, and their psychological reactions were taken into consideration. RESULTS: Eleven of the children and adolescents who had nasal fracture without dislocation, who have no symptoms, minimal swelling, and no septal deviation or hematoma, were observed with a specific follow-up: 3 days after nasal fracture, then every week in the first month, after 1 month, and after 3 months period. Sixteen of children and adolescents who had a nasal fracture with subluxation of nasal septum were operated with closed reduction (repositio nasi) under general anaesthesia. The others with septal hematomas and subperichondrial abscess were treated as in adults' patients. The second group of 41 children and adolescents from 6-14 years old consisted with with the previous nasal trauma which was not treated on time or it was improperly treated. In 24 (58.54%) of these patients septoplasty was performed and in 17 (41.46%) was performed rhino septoplasty. CONCLUSION: Often, difficult septal deformations in children are followed with deformation of the nasal pyramid (rhino scoliosis, rhino lordosis). In those cases, we cannot solve septal pathology without nasal pyramid intervention in the same time and opposite. Clinical reports have not produced solid evidence for the statement that septal surgery has no negative effect on nasal growth or can serve for correcting abnormal growth. The functional and esthetic problems of the patient, however, mean a continuous stimulus for further clinical and experimental investigations. PMID- 27703566 TI - Early Prognostic Factors for the Progress of Preeclampsia - Our Experience in the Period 2010-2011. AB - AIM: To determine the prognostic value of the low Pregnancy-associated plasma protein A (PAPP-A) levels in the early stages of pregnancy (11-13 weeks GA) independently and in combination with a Doppler test of the uterine arteries during the second half of pregnancy (22-23 weeks GA). MATERIAL AND METHODS: The study covered the period 2010-2011 and included 106 pregnant women, aged 35-40, with a single child pregnancy. The research excluded pregnant women with anomalies of the fetus, smokers and women taking prophylactically low doses of aspirin. RESULTS: Thirty-six pregnant women had PAPP-A level below 0.4 MoM, whereas 20 of them developed preeclampsia and 7 - early preeclampsia. The combination of the low PAPP-A values and the abnormal Doppler test of the uterine arteries is with a considerably better prognostic value in regards to the risk of developing preeclampsia. CONCLUSION: The Doppler test is a non-invasive, quick and easy method for assessment of the uterine-placental blood flow. PMID- 27703567 TI - The Association between Malnutrition and Pressure Ulcers in Elderly in Long-Term Care Facility. AB - BACKGROUND: Malnutrition is common in elderly and is a risk factor for pressure ulcers. AIM: The aim of the present study was to determine the prevalence of malnutrition in geriatric and palliative patients hospitalised in long-term care facility, and to examine the influence of nutritional status on the prevalence of pressure ulcers (PU). MATERIAL AND METHODS: Descriptive, observational and cross sectional study including 2099 patients admitted to the Hospital during a 24 month period (January 2013 to December 2014). We recorded: demographic data, body mass index (BMI), Braden score, laboratory parameters of interest (albumin, total protein, RBC count, haemoglobin and iron levels) and presence or absence of malnutrition and pressure ulcers. RESULTS: The pressure ulcer prevalence was 12.9% (256 out of 2099). Based on the BMI classification, 61.7% of patients had a good nutritional status, 27.4% were undernourished, and 2.1% were considered malnourished. Nutritional status was statistically significantly different between patients with and without PU (p < 0.0001). This study also showed that hypoproteinemia, hypoalbuminemia, low RBC was positively associated with PU prevalence. CONCLUSION: The results highlight the impact of nutritional status on the prevalence of pressure ulcers in hospitalised geriatric and palliative population. It is of paramount importance to correctly evaluate the presence of malnutrition in patients at risk of pressure ulcers. PMID- 27703568 TI - Clinical, Laboratory and Radiographic Features of Patients with Pneumonia and Parapneumonic Effusions. AB - BACKGROUND: Parapneumonic effusions complicating pneumonia are associated with increased morbidity and mortality. AIM: To determine the role of the clinical, laboratory and radiographic features to the differential diagnosis of patients with community- acquired pneumonia (CAP) without effusion, uncomplicated parapneumonic effusion (UCPPE) and complicated parapneumonic effusion (CPPE). MATERIAL AND METHODS: We analysed 148 patients with CAP without effusion, 50 with UCPPE and 44 with CPPE. In three groups of patients, the majority was male patients (58.11%, 58%, 61.36%) consequently. RESULTS: The chronic heart failure was the most common comorbidity in a group with CAP (28; 18.92%) and UCPPE (7; 14%), alcoholism (12;12.77%) in a group with CPPE. Patients with CPPE had significantly longer fever compared to patients with CAP without effusion (p = 0.003). Pleuritic chest pain (86.36%) and dyspnea (88.64%) were the most common symptoms in CPPE, then to group with UCPPE (60%; 52%), and in CAP without effusion (25.68%; 47,97%). Diffuse pulmonary changes were detected more frequently in the group with CAP without effusion compared with the group with CPPE (64.86 % vs. 27.27 %), while the segment lung changes were more common in patients with CPPE (50% vs. 20.27%). Patients with CPPE were significant with higher erythrocytes sedimentation rate (ESR), white blood cells (WBC) and serum C reactive protein (CRP) than it the other two groups (p = 0.00090, p = 0.01, p= 0.000065). CONCLUSION: Proper analysis of clinical, laboratory and radiographic features of patients with CAP and parapneumonic effusion can prevent mismanagement in these patients and will reduce morbidity and mortality. PMID- 27703569 TI - Heart Failure Predictors in a Group of Patients with Myocardial Infarction. AB - AIM: The present study considers of the prevalence of heart failure (HF) in patients suffering from acute myocardial infarction (AMI) in the University Hospital Centre of Tirana (UHCT) "Mother Theresa"; the demographic and clinical characteristics of the sample during hospitalization; and the main predictors of heart failure occurrence inside the group of patients suffering an AMI. MATERIAL AND METHODS: During a period of study from 2013-2015 we studied demographic and clinical data from 587 consecutive patients presenting with AMI; Framingham criteria were adopted for classifying patients with HF upon admission. RESULTS: A Killip class >= 2 was the main diagnostic criterion of HF during hospitalisation. HF was identified in 156 patients (26.6%). The subgroup with HF had significant differences when compared with the other patients with regard to age, sex (male), heart rate upon admission, systolic blood pressure on admission, previous episodes of AMI, glycemia on admission, previous antihypertensive treatment, previous revascularization procedures, peripheral vascular disease, chronic renal disease, ejection fraction (EF), anemia, and atrial fibrillation presence. Independent predictors for HF occurrence in the logistic regression model were EF, previous revascularization, peripheral vascular disease, age, sex, previous AMI, systolic blood pressure upon admission, and anaemia. CONCLUSION: As a conclusion, HF seems to be a common occurrence after AMI, in spite of changes in the epidemiological profile of the acute coronary syndrome. An increase in the incidence is registered as well, parallel to a decrease in the mortality following AMI. Attention must be shown for highly risked subpopulations, aged persons, patients with the previous coronary disease, and concomitant conditions. PMID- 27703570 TI - Two Pregnancies with a Different Outcome in a Patient with Alport Syndrome. AB - BACKGROUND: Alport syndrome is a genetic disease that progresses to chronic kidney failure, with X-linked, autosomal dominant or autosomal recessive type of inheritance. Women are generally carriers of the mutation and have a milder form of the disease. During pregnancy, they have an increased risk of impaired kidney function and preeclampsia. CASE PRESENTATION: A 27-year old woman, gravida 1, para 0, in her 23rd gestational week came to the outpatient unit of the University Clinic of Nephrology for the first time because of slowly progressing proteinuria and Alport syndrome. She was admitted to the gynaecological ward in her 29th gw for proteinuria which increased from 3.8 g/day up to 20 g/day and the serum creatinine increased to 120- 150 micromol/l. She was delivered in the 30th gestational week due to obstetrical indications with a cesarian section and delivered a baby with a birth weight of 880 g. After delivery, proteinuria decreased to 2 g/d within 2 months and an angiotensin-converting enzyme inhibitor (ACEI) was started. Her second pregnancy, after 2 years, had an uneventful course and she delivered a healthy baby weighing 3000 g in the 39th week. Six months after the second delivery, her renal function remained normal and her proteinuria was 2 g/d. CONCLUSIONS: Pre-pregnancy counselling and frequent controls during pregnancy are necessary for women with Alport syndrome, as well as regular monitoring after delivery. Recent reports are more in favour of good pregnancy and nephrological outcomes in women with Alport syndrome when renal disease is not advanced. PMID- 27703571 TI - The Role of Rehabilitation in the Management of Patients with Charcot-Marie-Tooth Disease: Report of Two Cases. AB - BACKGROUND: Charcot-Marie-Tooth (CMT) disease is a hereditary disease with signs of chronic non-progressive motor-sensory neuropathy which is characterised by symmetric muscle atrophy and weakness of the distal portion of lower extremities. AIM: The aim is to present two cases with peroneal muscular atrophy, applied rehabilitation procedures and rehabilitation outcome. MATERIAL AND METHODS: Patient DR, aged 51, and patient KH, aged 78. Both patients had weakness and pronounced atrophy of the distal portion of lower extremities, numbness down the legs, contractures in the ankles and walking difficulties. Evaluation of patients included a clinical examination, Barthel Index, Time Up and Go test, measurement of the ankle range of motion, and a manual muscle test. On admission, the Barthel Index score was 60 in the first case, and 80 in the second. The rehabilitation program included exercise therapy with for lower extremity, occupational therapy, stationary bicycle riding, galvanic current, water exercises, and ankle-foot orthoses for both legs. RESULTS: The therapy applied had no significant changes in the clinical neurological status of the patients, but yet it provided some improvement in ankle contractures, better mobility, and a more stable gait. CONCLUSION: The application of rehabilitation procedures in patients with Charcot Marie-Tooth disease can improve their functional status and walking stability. PMID- 27703572 TI - Cytomegalovirus Infection during Pregnancy and Its Impact on the Intrauterine Fetal Development - Case Report. AB - AIM: The aim of this publication is to present a case of CMV infection during pregnancy, with clinical manifestations of the development of microcephaly and simultaneous dilatation of the 3rd and 4th brain ventricle at 23 weeks gestation. This article discusses the role of ultrasound screening in the second trimester of pregnancy. CASE PRESENTATION: We present the case of a 25-year-old woman with the initials S.K. in her second pregnancy that came to our antenatal Consulting Centre. The first screening for blood count, blood group, biochemistry and serology showed results within the reference range. The patient came for a second comprehensive biochemical screening at 17 - 18 weeks gestation. The results showed the low genetic risk of congenital anomalies. Fetal morphology of the fetus was normal. S.K. came again for consultation at 22 weeks gestation in connection with the admittance of her first 3-year-old child to the hospital because of pneumonia. Serological tests of the child had shown elevated CMV titer - specific IgM. Then we made new serological tests of the patient and the results have shown that the patient was most likely infected by CMV primarily in the first trimester of pregnancy. After consulting about the risk of transmission of CMV to the fetus, the woman chose monthly ultrasound scans and refused amniocentesis. At 36 weeks gestation, in addition to the microcephaly already established, enlargement of the IV brain ventricle at the expense of underdevelopment of the cerebellum was noticed. Also, 2nd to 3rd stage of placenta maturity and low quantity of amniotic fluid was established. A male fetus of weight 2,890 g and height 50 cm was delivered. The fetus was with skin petechiae and hepatosplenomegaly. Neurological examination showed no abnormalities. CONCLUSIONS: In the described case the time interval between infection and ultrasonic manifestations is more than 17 weeks. The long interval between infection and occurrence of ultrasound markers can be a good prediction sign, as it may reflect less aggressive viral infection than present in cases where similar ultrasound findings were obtained shortly after infection of the mother. PMID- 27703573 TI - Enduring Personality Changes after Intense Stressful Event: Case Report. AB - BACKGROUND: World statistical data show that a large number of individuals suffer from posttraumatic stress disorder (PTSD) after exposure to the intense traumatic event. PTSD can have a chronic course with enduring changes in the functioning of the person. CASE PRESENTATION: Here we report two adult individuals of different gender and education who were exposed to the extremely severe stressful event after which difficulties in psychological functioning developed. The first case we present is a 46-year-old man, with completed high education, divorced, father of two children, who lives with his parents, and is retired. Disorders appeared 20 years ago when he was exposed to extremely severe stressful events in war circumstances that included captivity, torture, and loss of fellow soldiers. The second case is a 50-year-old female patient, with a university degree, professor of art, married, and mother of two children of whom the son died six years ago. She suffered from disorders after the sudden injury of her son that ended with his death. CONCLUSION: Posttraumatic stress disorder after the intense stress is a risk of development enduring personality changes with serious individual and social consequences. PMID- 27703574 TI - Aortic Annular Enlargement during Aortic Valve Replacement. AB - In the surgery of aortic valve replacement is always attempted, as much as possible, to implant the larger prosthesis with the mains goals to enhance the potential benefits, to minimise transvalvular gradient, decrease left ventricular size and avoid the phenomenon of patient-prosthesis mismatch. Implantation of an ideal prosthesis often it is not possible, due to a small aortic annulus. A variety of aortic annulus enlargement techniques is reported to avoid patient prosthesis mismatch. We present the case that has submitted four three times open heart surgery. We used Manouguian technique to enlarge aortic anulus with excellent results during the fourth time of surgery.

This institute comprises the rights of the patients with mental health disorders. The aim of this paper is to explain the contemporary mental health legislation in our country the Republic of Macedonia and the problems with the implementation of involuntary hospitalisation. This could be overcome with close cooperation between the judicial and health care system. PMID- 27703576 TI - Characterization and Cytotoxicity Analysis of a Ciprofloxacin Loaded Chitosan/Bioglass Scaffold on Cultured Human Periodontal Ligament Stem Cells: a Preliminary Report. AB - AIM: The aim of this study was to analyze the cytotoxicity of ciprofloxacin (CIP) loaded on chitosan bioactive glass scaffold on human periodontal ligament stem cells (PLSCs) in vitro. MATERIALS AND METHODS: PLSCs obtained from human third molars, cultures treated with medium containing 15 x 15 mm chitosan/bioactive glass scaffolds without/with different concentration 0, 5, 10, and 20 % of CIP. A total of 15 x 10^3 cells were plated in 6 well plates. The attached cells of each group were harvested from the plates after 1, 4 and 8 days of culture to detect the viability of cells. The cell number was determined using a hemocytometer and the trypan blue dye-exclusion assay. Data was analyzed using normality using Shapiro-Wilk test. Comparisons between groups were made using One-way ANOVA complemented by Tukey's test. RESULTS: When comparing the proliferation rate of cells in the four groups, no statistically significant difference was found (P = 0.633). With regards to cell viability, no statistical difference was found between the 0, 5, and 10 % CIP concentrations, while the 20 % CIP concentration demonstrated the least viability with a high statistically significant difference (P = 0.003). CONCLUSION: Twenty percentages CIP demonstrated the least proliferation rate and viability. PMID- 27703577 TI - Midfacial Reconstruction - A Systematic Review. AB - AIM: Different lesions affecting the midfacial regions require surgical reconstruction. The aim of this study was to assess the different methods used in midfacial reconstruction after maxillectomy procedures. The various reported surgical reconstructive techniques focusing on the esthetic and functional outcomes are to be reviewed in this article. MATERIAL AND METHODS: A thorough PUBMED and hand-search of journals of relevance was performed on related terms and yielded 772 titles of which 45 abstracts were selected and obtained as full articles for further evaluation while the rest were excluded by title/abstract. According to the inclusion criteria; 14 of these studies were used to complete this article. RESULTS: In this review we showed that fibular and radial vascularized grafts were the most commonly reported methods in literature with a few other options. Computer aided design and surgical planning has been also reviewed and seems to be a rapidly evolving option for maxillofacial reconstruction. Lack of RCTs (randomized controlled trials) and large scale case series was noticed in this review making the evidence of poor quality. CONCLUSION: Methods of evaluation of reconstruction options mainly qualitative and subjective made the evaluation of the techniques in this review difficult. PMID- 27703578 TI - A Comparative Clinical Study of the Effect of Denture Cleansing on the Surface Roughness and Hardness of Two Denture Base Materials. AB - AIM: This study aimed to verify the influence of oral environment and denture cleansers on the surface roughness and hardness of two different denture base materials. METHODS: A total of sixteen identical removable disc specimens (RDS) were processed. Eight RDS were made from heat-cured acrylic resin (AR) and the other eight were fabricated from thermoplastic injection moulded resin (TR). Surface roughness and hardness of DRS were measured using ultrasonic profilometry and Universal testing machine respectively. Then the four RDS (two AR and two of TR) were fixed to each maxillary denture, after three months RDS were retrieved. Surface roughness and hardness of RDS have measured again. RESULTS: The surface roughness measurements revealed no significant difference (p >0.05) for both disc groups at baseline. However, both groups showed a significant increase in the surface roughness after three months with higher mean value for (TR) group. On the other hand, the (AR) group showed higher hardness mean value than (TR) group at baseline with no significant decrease in the hardness values (p >0.05) following three months follow-up period. CONCLUSIONS: Denture cleansers have an effect on the denture's surface roughness and hardness concurrently with an oral condition which will consequently influence the complete dentures' lifetime and patients' satisfaction. PMID- 27703579 TI - A Comparative Study of Transbuccal and Extraoral Approaches in the Management of Mandibular Angle Fractures: A Systematic Review. AB - AIM: The aim of the present study was to compare the extraoral and transbuccal approaches for the treatment of mandibular angle fractures with regard to postoperative complications. PATIENTS AND METHODS: An electronic search for relevant articles without language and date restrictions was performed in July 2016. Inclusion criteria were studies in humans including randomised controlled trials (RCTs), controlled clinical trials (CCTs), prospective studies (PS), and retrospective studies (RS). In total, 107 patients were included from four studies (transbuccal = 48, extraoral = 59). The follow-up period varied from 3 months to 24 months. RESULTS: In extraoral group the average of unsightly scar, facial nerve weakness, infection, malocclusion, plate removal were found to be 55% (range, 10% -100%), 26.5% (range, 0%-53%), 11.7% (range, 0% - 20%), 22.5% (range, 0% -50%), 6.7% (range, 3.3% - 10%) respectively while these parameters in the transbuccal approach were found to be no obvious unsightly scar, 6.6 % (range, 0%-13.3%), 8.1% (range, 0% - 20%), 4.8% (range, 0% - 12.5%), 0%. The incidence of postoperative trismus and nonunion/malunion were 0% in both groups. CONCLUSION: The results of this study suggest that transbuccal approach shows fewer complications than extraoral approach when used for the treatment of mandibular angle fractures. PMID- 27703580 TI - Managing the Cutaneous Sinus Tract of Dental Origine. AB - BACKGROUND: Draining cutaneous sinus tract in chin area may be caused by chronic periapical dental infections. Misdiagnosis of these lesions usually leads to destructive invasive treatment of the sinus tract that is not correct and curative. CASE REPORT: A 31-year-old male patient referred to us with a chronically draining lesion on his chin. The lesion previously was misdiagnosed by medical doctors and had undergone two times surgery with a focus on the skin lesion and had received antibiotic therapy for a prolonged period of time. After clinical and radiologic examination the dental origin of the lesion was evident and proper endodontic and surgical treatment was performed. Three months later, after the treatment, the lesion showed total healing and reoccurrence occurred. CONCLUSION: The key to successful treatment of cutaneous sinus tract of dental origin must be in appropriate communication between the dentist and the physician in order to achieve correct diagnosis and therapy in such cases. PMID- 27703581 TI - Allostatic Load Assessment for Early Detection of Stress in the Workplace in Egypt. AB - AIM: Workplace stress is hazardous for its harmful impact on employees' health and organizational productivity. The aim of the study is to apply the Allostatic Load Index (ALI) which is a multi-component measure for health risk assessment and early detection of stress among workers in Egypt. METHODS: Sixty-two working adults randomly selected from two different working environments in Egypt were included in the study. Participants completed a self-reported questionnaire for socio-demographic and work variables. Andrews and Withey test for Job Satisfaction was filled and 3 ml blood samples were collected. Markers assessed for Allostatic Load were serum cortisol, c-reactive protein, dehydroepiandrosterone-sulphate, total thyroxine, total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, total cholesterol to high-density lipoprotein ratio, systolic and diastolic blood pressures, waist to hip ratio and body mass index. The risk quartile method was used for calculation of ALI. ALI value of four or more indicates high Allostatic Load. RESULTS: Job satisfaction scale defined about a quarter of the study population (24%) to be dissatisfied with Allostatic Load of 2.4 as the mean value. Population percentage with ALI >=4 reached 12.9% with 100% of them females. A significant association was found between Allostatic Load of primary mediators and age, the presence of chronic diseases, place of work and female gender. CONCLUSION: Female gender and the old age of the Egyptian workforce under study are at higher risk of chronic diseases. Using an alternative way -for example, the cut-point method- instead of the risk quartiles for dichotomization of markers used in ALI calculation could be more precise for early detection of stress among healthy individuals. PMID- 27703582 TI - Analysis of Marketing Strategy for Food Supplements and Over-The-Counter Medicines. AB - Marketing strategy is correlated with the regulations for the corresponding product category. Accordingly, there is a big difference in the marketing strategy of food supplements and over-the-counter medicines. In this paper are presented 2 different marketing strategies of a new small pharmaceutical company in two studies. The findings of studies analysis can be used for developing marketing strategies in the wider sense and other products, for other small to medium sized companies in other countries of interest with similar regulations and help them understand how to position and promote themselves and their products. PMID- 27703583 TI - A Worksite Health Education Workshop as Empowerment Intervention for Health Promotion in the National Research Centre of Egypt. AB - AIM: The study aimed to assess worksite health education workshops as a successful tool for health promotion of employees. MATERIAL AND METHODS: A one day workshop was held for individuals engaged in research activities in the National research Centre of Egypt at the worksite. Its main objective was to highlight the nature, causes, symptoms and management of job stress. Participants were asked to fill a personality assessment sheet, a self-reported questionnaire for job satisfaction. Other questionnaires for assessment of falsification of type and some socio-demographic data were filled by the attendants. A concise survey was introduced at the end of the workshop for feedback collection. RESULTS: Attendants of the workshop were 36 subjects mainly females (94.4%). Mean age was 40.5 years with 63.9% of participants at their postdoctoral studies stage. Participants were at midway in the scale of job satisfaction (3.3) and did not suffer from falsification (0.3). The feedback survey score (11.5) showed great acceptance for the intervention. Special interest in the topic of stress was reported by 35.1% of attendants who found it the best item in the workshop and the interactive manipulation came next as declared by 18.9% of the participants. CONCLUSION: Worksite health education workshops seem to be a successful practice for empowerment in the Egyptian workplace. PMID- 27703585 TI - Etiopathogenesis of Differentiated Thyroid Carcinomas. AB - INTRODUCTION: Thyroid malignomas are a heterogeneous group of neoplasm consisting of most frequent differentiated encountered carcinomas, papillary and follicular thyroid carcinoma, then medullary thyroid carcinoma originating from neuroendocrine calcitonin-producing C-cells and rare forms of thyroid lymphomas arising from intrathyroidal lymphatic tissue, thyroid sarcomas and poorly differentiated anaplastic thyroid carcinoma. There are increasing numbers of epidemiological studies and publications that have suggested increased incidence rate of thyroid carcinomas. We have read, analysed and compare available reviews and original articles investigating different etiological factors in the development of thyroid carcinomas through Google Scholar and PubMed Database. DISCUSSION: Aetiology involved in the development of thyroid carcinomas is multifactorial and includes external influences, as well as constitutional predispositions and genetic etiological factors. The actual effect of environmental and constitutional factors is on promoting genetic and epigenetic alterations which result in cell proliferation and oncogenesis. Until now are identified numerous genetic alterations, assumed to have an important role in oncogenesis, with MAPK and PI3K-AKT as crucial signalling networks regulating growth, proliferation, differentiation and cell survival/apoptosis. CONCLUSION: This new molecular insight could have a crucial impact on diagnosis and also on improving and selecting an appropriate treatment to the patients with thyroid malignancies. PMID- 27703586 TI - Venous Thromboembolism - Current Diagnostic and Treatment Modalities. AB - BACKGROUND: Pulmonary embolism and deep venous thrombosis, known as venous thromboembolism (VTE), are associated with a high proportion of morbidity and mortality. AIM: Aim of this review is to emphasise current diagnostic and therapeutic modalities for VTE. RESULTS: No differences have been noticed in European and American guidelines in diagnostic approach of this disorder. Today there is enough clinical information for the use of heparin (either, unfractionated or low molecular) and vitamin K antagonists in the treatment of acute and chronic phases of VTE. Novel oral anticoagulants seem to have some advantages in the treatment of this disorder. Rivaroxaban has been approved widespread, for use as a single-drug approach of VTE. CONCLUSION: Both guidelines are almost similar and good basis for evidence-based treatment of this disorder. PMID- 27703584 TI - The Role of Levosimendan in Patients with Decreased Left Ventricular Function Undergoing Cardiac Surgery. AB - The postoperative low cardiac output is one of the most important complications following cardiac surgery and is associated with increased morbidity and mortality. The condition requires inotropic support to achieve adequate hemodynamic status and tissue perfusion. While catecholamines are utilised as a standard therapy in cardiac surgery, their use is limited due to increased oxygen consumption. Levosimendan is calcium sensitising inodilatator expressing positive inotropic effect by binding with cardiac troponin C without increasing oxygen demand. Furthermore, the drug opens potassium ATP (KATP) channels in cardiac mitochondria and in the vascular muscle cells, showing cardioprotective and vasodilator properties, respectively. In the past decade, levosimendan demonstrated promising results in treating patients with reduced left ventricular function when administered in peri- or post- operative settings. In addition, pre operative use of levosimendan in patients with severely reduced left ventricular ejection fraction may reduce the requirements for postoperative inotropic support, mechanical support, duration of intensive care unit stay as well as hospital stay and a decrease in post-operative mortality. However, larger studies are needed to clarify clinical advantages of levosimendan versus conventional inotropes. PMID- 27703587 TI - An Updated Mini Review of Vitamin D and Obesity: Adipogenesis and Inflammation State. AB - Vitamin D related research continues to expand and theorise regarding its involvement in obesity, as both hypovitaminosis D and obesity strike in pandemic proportions. Vitamin D plays an important role in immune system through Vitamin D Receptors (VDR), which are transcription factors located abundantly in the body. Due to this characteristic, it is potentially linked to obesity, which is a state of inflammation involving the release of cytokines from adipose tissue, and exerting stress on other organs in a state of positive energy balance. Research trials in the past couple of years and systematic reviews from SCOPUS and MEDLINE will be discussed. The role of Vitamin D throughout the lifespan (from fetal imprinting until older age), and in various other obesity mediated chronic conditions shall be highlighted. Various mechanisms attributed to the inverse relationship of Vitamin D and obesity are discussed with research gaps identified, particularly the role of adipokines, epigenetics, calcium and type of adipose tissue. PMID- 27703588 TI - How to Verify and Manage the Translational Plagiarism? AB - The use of Google translator as a tool for determining translational plagiarism is a big challenge. As noted, plagiarism of the original papers written in Macedonian and translated into other languages can be verified after computerised translation in other languages. Attempts to screen the translational plagiarism should be supported. The use of Google Translate tool might be helpful. Special focus should be on any non-English reference that might be the source of plagiarised material and non-English article that might translate from an original English article, which cannot be detected by simple plagiarism screening tool. It is a hard job for any journal to detect the complex translational plagiarism but the harder job might be how to effectively manage the case. PMID- 27703589 TI - Particle rotational trapping on a floating electrode by rotating induced-charge electroosmosis. AB - We describe a novel rotating trait of induced-charge electroosmotic slip above a planar metal surface, a phenomenon termed "Rotating induced-charge electro osmosis" (ROT-ICEO), in the context of a new microfluidic technology for tunable particle rotation or rotational trap. ROT-ICEO has a dynamic flow stagnation line (FSL) that rotates synchronously with a background circularly polarized electric field. We reveal that the rotating FSL of ROT-ICEO gives rise to a net hydrodynamic torque that is responsible for rotating fluids or particles in the direction of the applied rotating electric field either synchronously or asynchronously, the magnitude of which is adjusted by a balance between rotation of FSL and amplitude of angular-direction flow component oscillating at twice the field frequency. Supported by experimental observation, our physical demonstration with ROT-ICEO proves invaluable for the design of flexible electrokinetic framework in modern microfluidic system. PMID- 27703590 TI - Sheathless electrokinetic particle separation in a bifurcating microchannel. AB - Particle separation has found practical applications in many areas from industry to academia. Current electrokinetic particle separation techniques primarily rely on dielectrophoresis, where the electric field gradients are generated by either active microelectrodes or inert micro-insulators. We develop herein a new type of electrokinetic method to continuously separate particles in a bifurcating microchannel. This sheath-free separation makes use of the inherent wall-induced electrical lift to focus particles towards the centerline of the main-branch and then deflect them to size-dependent flow paths in each side-branch. A theoretical model is also developed to understand such a size-based separation, which simulates the experimental observations with a good agreement. This electric field-driven sheathless separation can potentially be operated in a parallel or cascade mode to increase the particle throughput or resolution.

AB - The ability to drive microcentrifugation for efficient micromixing and particle concentration and separation on a microfluidic platform is critical for a wide range of lab-on-a-chip applications. In this work, we investigate the use of amplitude modulation to enhance the efficiency of the microcentrifugal recirculation flows in surface acoustic wave microfluidic systems, thus concomitantly reducing the power consumption in these devices for a given performance requirement-a crucial step in the development of miniaturized, integrated circuits for true portable functionality. In particular, we show that it is possible to obtain an increase of up to 60% in the acoustic streaming velocity in a microdroplet with kHz order modulation frequencies due to the intensification in Eckart streaming; the streaming velocity is increasing as the modulation index is increased. Additionally, we show that it is possible to exploit this streaming enhancement to effect improvements in the speed of particle concentration by up to 70% and the efficiency of micromixing by 50%, together with a modest decrease in the droplet temperature. PMID- 27703591 TI - Development of an advanced microfluidic micropipette aspiration device for single cell mechanics studies. AB - Various micro-engineered tools or platforms have been developed recently for cell mechanics studies based on acoustic, magnetic, and optical actuations. Compared with other techniques for single cell manipulations, microfluidics has the advantages with simple working principles and device implementations. In this work, we develop a multi-layer microfluidic pipette aspiration device integrated with pneumatically actuated microfluidic control valves. This configuration enables decoupling of cell trapping and aspiration, and hence causes less mechanical perturbation on trapped single cells before aspiration. A high trapping efficiency is achieved by the microfluidic channel design based on fluid resistance model and deterministic microfluidics. Compared to conventional micropipette aspiration, the suction pressure applied on the aspirating cells is highly stable due to the viscous nature of low Reynolds number flow. As a proof of-concept of this novel microfluidic technology, we built a microfluidic pipette aspiration device with 2 * 13 trapping arrays and used this device to measure the stiffness of a human breast cancer cell line, MDA-MB-231, through the observation of cell deformations during aspiration. As a comparison, we studied the effect of Taxol, a FDA-approved anticancer drug on single cancer cell stiffness. We found that cancer cells treated with Taxol were less deformable with a higher Young's modulus. The multi-layer microfluidic pipette aspiration device is a scalable technology for single cell mechanophenotyping studies and drug discovery applications.

AB - As the field of colloidal science continues to expand, tools for rapid and accurate physiochemical characterization of colloidal particles will become increasingly important. Here, we present Particle Scattering Diffusometry (PSD), a method that utilizes dark field microscopy and the principles of particle image velocimetry to measure the diffusivity of particles undergoing Brownian motion. PSD measures the diffusion coefficient of particles as small as 30 nm in diameter and is used to characterize changes in particle size and distribution as a function of small, label-free, surface modifications of particles. We demonstrate the rapid sizing of particles using three orders-of-magnitude less sample volume than current standard techniques and use PSD to quantify particle uniformity. Furthermore, PSD is sensitive enough to detect biomolecular surface modifications of nanometer thickness. With these capabilities, PSD can reliably aid in a wide variety of applications, including colloid sizing, particle corona characterization, protein footprinting, and quantifying biomolecule activity. PMID- 27703594 TI - Capillary flow of blood in a microchannel with differential wetting for blood plasma separation and on-chip glucose detection. AB - We report capillary flow of blood in a microchannel with differential wetting for the separation of a plasma from sample blood and subsequent on-chip detection of glucose present in a plasma. A rectangular polydimethylsiloxane microchannel with hydrophilic walls (on three sides) achieved by using oxygen plasma exposure enables capillary flow of blood introduced at the device inlet through the microchannel. A hydrophobic region (on all four sides) in the microchannel impedes the flow of sample blood, and the accumulated blood cells at the region form a filter to facilitate the separation of a plasma. The modified wetting property of the walls and hence the device performance could be retained for a few weeks by covering the channels with deionised water. The effects of the channel cross-section, exposure time, waiting time, and location and length of the hydrophobic region on the volume of the collected plasma are studied. Using a channel cross-section of 1000 * 400 MUm, an exposure time of 2 min, a waiting time of 10 min, and a hydrophobic region of width 1.0 cm located at 10 mm from the device inlet, 450 nl of plasma was obtained within 15 min. The performance of the device was found to be unaffected (provides 450 nl of plasma in 15 min) even after 15 days. The purification efficiency and plasma recovery of the device were measured and found to be comparable with that obtained using the conventional centrifugation process. Detection of glucose at different concentrations in whole blood of normal and diabetic patients was performed (using 5 MUl of sample blood within 15 min) to demonstrate the compatibility of the device with integrated detection modules.

AB - Integrating a perfusable microvasculature system in vitro is a substantial challenge for "on-chip" tissue models. We have developed an inclusive on-chip platform that is capable of maintaining laminar flow through porous biosynthetic microvessels. The biomimetic microfluidic device is able to deliver and generate a steady perfusion of media containing small-molecule nutrients, drugs, and gases in three-dimensional cell cultures, while replicating flow-induced mechanical stimuli. Here, we characterize the diffusion of small molecules from the perfusate, across the microvessel wall, and into the matrix of a 3D cell culture. PMID- 27703597 TI - A study on usefulness of a set of known risk factors in predicting maternal syphilis infections in three districts of Western Province, Zambia. AB - INTRODUCTION: Despite roll-out of cost-effective point-of-care tests, less than half antenatal attendees in rural western Zambia are screened for syphilis. This study formulated a clinical, risk-based assessment criteria and evaluated its usefulness as a non-biomedical alternative for identifying high-risk prenatal cases. METHODS: We conducted a cross-sectional survey of antenatal clinic attendees in Kaoma, Luampa and Nkeyema districts to collect data on exposure to nine pre-selected syphilis risk factors. These factors were classified into major and minor factors based on their observed pre-study association strengths to maternal syphilis. Clinical disease was defined as exposure to either two major factors, one major with two minor factors or three minor factors. Sensitivity, specificity and predictive values of the clinical protocol were then calculated in comparison to rapid plasmin reagin results. RESULTS: The observed syphilis prevalence was 9.3% (95% CI: 7.4 - 11.6%) and the overall sensitivity of the study criteria was 62.3% with positive predictive value of 72.9%. Sensitivities of individual case-defining categories were even lower; from 17.4% to 33.3%. Results confirmed that abortion history, still birth, multiple sexual partners, previous maternal syphilis infection, partner history of sexually transmitted infection and maternal co-morbid conditions of HIV and genital ulcer disease were significantly associated to maternal syphilis in study population as well. CONCLUSION: The criteria was not as effective as biomedical tests in identifying maternal syphilis. However, it could be a useful adjunct/alternative in antenatal clinics when biomedical tests are either inadequate or unavailable. PMID- 27703598 TI - Cognitive function in Nigerian children with newly diagnosed epilepsy: a preliminary report. AB - INTRODUCTION: Epilepsy has long been associated with cognitive dysfunction and educational underachievement. The purpose of the study was to describe the baseline findings from a larger prospective study. METHODS: New cases of epilepsy aged 6-16 years seen at a paediatric neurology clinic in Ibadan, Nigeria were evaluated for any evidence of cognitive impairment. Intelligence quotient (IQ) of the participants was measured using the Wechsler Intelligence Scale for Children Fourth Edition (WISC-IV). Scores on cognitive subtests and Full Scale IQ (FSIQ) were computed and association between the subsets scores and seizure variables were calculated. RESULTS: 40 children, 24 males and 16 females were studied and their ages ranged from 6 to 16 years with a mean of 10.8 (SD=3.0) years. Global intellectual functioning as measured by the WISC-IV was in the normal range (FSIQ scores <85) for 52.5% (n = 21) of the participants and the remaining participants (47.5%) scored between the borderline and severe category for intellectual disability. The strongest correlation was between 'caregiver's assessment of school performance' and FSIQ, (r = 0.70; p< 0.001). Age at onset of epilepsy and seizure type had no significant association with scores on the WISC-IV composite scores. CONCLUSION: There is a high prevalence of significant cognitive dysfunction in Nigerian children with epilepsy, even in the absence of any known brain insult. All children with epilepsy should have routine IQ assessment following diagnosis, in order to allow for early intervention when indicated, and thus, improved outcomes. PMID- 27703599 TI - Antioxidant-Enhancing Property of the Polar Fraction of Mangosteen Pericarp Extract and Evaluation of Its Safety in Humans. AB - Crude extract from the pericarp of the mangosteen (mangosteen extract [ME]) has exhibited several medicinal properties in both animal models and human cell lines. Interestingly, the cytotoxic activities were always observed in nonpolar fraction of the extract whereas the potent antioxidant was often found in polar fraction. Although it has been demonstrated that the polar fraction of ME exhibited the antioxidant activity, the safety of the polar fraction of ME has never been thoroughly investigated in humans. In this study, we investigated the safety of oral administration of the polar fraction of ME in 11 healthy Thai volunteers. During a 24-week period of the study, only minor and tolerable side effects were reported; no serious side effects were documented. Blood chemistry studies also showed no liver damage or kidney dysfunction in all subjects. We also demonstrated antioxidant property of the polar fraction of ME both in vitro and in vivo. Interestingly, oral administration of the polar fraction of ME enhanced the antioxidant capability of red blood cells and decreased oxidative damage to proteins within red blood cells and whole blood. PMID- 27703600 TI - Cholesterol Retards Senescence in Bone Marrow Mesenchymal Stem Cells by Modulating Autophagy and ROS/p53/p21Cip1/Waf1 Pathway. AB - In the present study, we demonstrated that bone marrow mesenchymal stem cells (BMSCs) of the 3rd passage displayed the senescence-associated phenotypes characterized with increased activity of SA-beta-gal, altered autophagy, and increased G1 cell cycle arrest, ROS production, and expression of p53 and p21Cip1/Waf1 compared with BMSCs of the 1st passage. Cholesterol (CH) reduced the number of SA-beta-gal positive cells in a dose-dependent manner in aging BMSCs induced by H2O2 and the 3rd passage BMSCs. Moreover, CH inhibited the production of ROS and expression of p53 and p21Cip1/Waf1 in both cellular senescence models and decreased the percentage of BMSCs in G1 cell cycle in the 3rd passage BMSCs. CH prevented the increase in SA-beta-gal positive cells induced by RITA (reactivation of p53 and induction of tumor cell apoptosis, a p53 activator) or 3 MA (3-methyladenine, an autophagy inhibitor). Our results indicate that CH not only is a structural component of cell membrane but also functionally contributes to regulating cellular senescence by modulating cell cycle, autophagy, and the ROS/p53/p21Cip1/Waf1 signaling pathway. PMID- 27703601 TI - In vitro evaluation of efficacy of different rotary instrument systems for gutta percha removal during root canal retreatment. AB - BACKGROUND: Complete removal of old filling material during root canal retreatment is fundamental for predictable cleaning and shaping of canal anatomy. Most of the retreatment methods tested in earlier studies have shown inability to achieve complete removal of root canal filling. Therefore the aim of this investigation was to assess the efficacy of three different rotary nickel titanium retreatment systems and Hedstrom files in removing filling material from root canals. MATERIAL AND METHODS: Sixty extracted mandibular premolars were decoronated to leave 15 mm root. Specimen were hand instrumented and obturated using gutta percha and AH plus root canal sealer. After storage period of two weeks, roots were retreated with three (Protaper retreatment files, Mtwo retreatment files, NRT GPR) rotary retreatment instrument systems and Hedstroem files. Subsequently, samples were sectioned longitudinally and examined under stereomicroscope. Digital images were recorded and evaluated using Digital Image Analysing Software. The retreatment time was recorded for each tooth using a stopwatch. The area of canal and the residual filling material was recorded in mm2 and the percentage of remaining filling material on canal walls was calculated. Data was analysed using ANOVA test. RESULTS: Significantly less amount of residual filling material was present in protaper and Mtwo instrumented teeth (p < 0.05) compared to NRT GPR and Hedstrom files group. Protaper instruments also required lesser time during removal of filling material followed by Mtwo instruments, NRT GPR files and Hedstrom files. CONCLUSIONS: None of the instruments were able to remove the filling material completely from root canal. Protaper universal retreatment system and Mtwo retreatment files were more efficient and faster compared to NRT GPR fles and Hedstrom files. Key words:Gutta percha removal, nickel titanium, root canal retreatment, rotary instruments. PMID- 27703603 TI - Effectiveness of Amlexanox and Adcortyl for the treatment of recurrent aphthous ulcers. AB - BACKGROUND: Recurrent aphthous stomatitis (RAS) is a common condition that affects approximately 20% of the general population. The ulcers can interfere with speech and eating and cause significant pain and discomfort. This study aimed to evaluate the efficacy of Amlexanox and Adcortyl in the treatment of aphthous ulcers. MATERIAL AND METHODS: In this randomized double blind clinical trial with sequential patient entry, a total of 40 patients who presented with aphthous ulcers were included. Patients were received Amlexanox or Adcortyl four times daily for 7 days. Patients were evaluated for pain, lesion size, and tingling at one day, three days, five days and seven days follow-ups. The treatment effects were then evaluated using the Wilcoxon-Mann-Whitney (WMW) test. Values of p<0.05 were considered significant. RESULTS: No significant differences in pain score, tingling and lesion size were observed on similar days between Amlexanox and Adcortyl groups. In both groups, reduction in the assessed variables was significant between days 1-3, 3-5, and 5-7 (p < 0.001). CONCLUSIONS: This study indicated that Amlexanox as well as Adcortyl was effective in relieving pain and reducing the lesion size during the treatment of aphthous ulcers. Key words:Recurrent aphthous stomatitis, Amlexanox, Adcortyl, pain relief. PMID- 27703602 TI - Danger zone analysis using cone beam computed tomography after apical enlargement with K3 and K3XF in a manikin model. AB - BACKGROUND: The objective of the study was to evaluate and compare how apical enlargement with K3 and K3XF nickel-titanium (NiTi) rotary instruments reduces the root thickness in the danger zone and affects canal transportation and centering ability in mandibular molar mesial canals in a manikin extracted tooth model. MATERIAL AND METHODS: Seventy-two mesial root canals of first mandibular molars were instrumented. Initial and post-instrumentation Cone Beam Computed Tomography scans were performed after root canal preparation up to size 25, 30, 35 and 40 files. Canal transportation, canal centering and remaining root dentin thickness toward the danger zone were calculated in sections 1, 2 and 3 mm under the furcation level. Data were analyzed using non-parametric Kruskal-Wallis analysis of variance at a significance level of P < 0.05. RESULTS: K3 instruments removed more dentin toward the danger zone compared with K3XF instruments (P< .05) and significant differences in dentin thickness were found when canal enlargement was performed to a #35-40 with both systems (P< 0.05). No significant differences in canal transportation and centering ability were found between systems, except when canal enlargement was performed to a #40 (P = 0,0136). No differences were observed when comparing the number of uses in both systems (P> 0.05). CONCLUSIONS: Under the conditions of this study K3 removed a significant amount of dentin at the furcation level compared with the R-Phase K3XF rotary system in curved root canals. Enlargement to a 35-40/04 file removed significantly more dentin with both systems. Key words:K3, K3XF, R-phase, center ability, canal transportation, dentin thickness, increased apical enlargement, danger zone, dentin thickness. PMID- 27703604 TI - Effect of pre-heating on the mechanical properties of silorane-based and methacrylate-based composites. AB - BACKGROUND: The use of composites in dental restoration has been commonly criticized, due to their underwhelming mechanical properties. This problem may be solved partially by preheating. The present research aims to determine the effect of preheating on the mechanical properties of two different classes of composites. MATERIAL AND METHODS: A Silorane-based (Silorane) and a Methacrylate based (Z250) composite were preheated to different temperatures (25, 37, and 68 degrees C) and afterwards were tested with the appropriate devices for each testing protocol. The material's flexural strength, elastic modulus, and Vickers microhardness were evaluated. Two-way ANOVA, and Tukey's post hoc were used to analyze the data. RESULTS: Microhardness and elastic modulus increased with preheating, while flexural strength values did not increase significantly with preheating. Furthermore the methacrylate-based composite (Z250) showed higher values compared to the Silorane-based composite (Silorane) in all the tested properties. CONCLUSIONS: Preheating Silorane enhances the composite's microhardness and elastic modulus but does not affect its flexural strength. On the other hand, preheating Z250 increases its microhardness but does not change its flexural strength or elastic modulus. In addition, the Z250 composite shows higher microhardness and flexural strength than Silorane, but the elastic modulus values with preheating are similar. Therefore Z250 seems to have better mechanical properties making it the better choice in a clinical situation. Key words:Composite, elastic modulus, flexural strength, microhardness, preheating.

AB - BACKGROUND: This study aimed to determine knowledge, attitude and practice of airborne and droplet isolation precautions among Dental Health Professionals (DHPs) (dental students, interns, practitioners and auxiliaries) during the outbreak of MERS (Middle East Respiratory Syndrome), corona virus infection in Riyadh city, Saudi Arabia. MATERIAL AND METHODS: A cross-sectional survey was conducted among 406 dental health professionals (DHPs) working in selected dental facilities in Riyadh city, Saudi Arabia during the outbreak of MERS (April-June 2013). A structured, close-ended, self-administered questionnaire explored the knowledge, attitude, and practice towards droplet and isolation precautions. Collected data was subjected to descriptive statistics to express demographic information, mean knowledge score, mean attitude score and practice score of DHPs. Inferential statistics (Mann-Whitney U test and Kruskal Wallis tests, p < 0.05) were used to examine differences between study variables. Spearman's rho correlation was used to identify the association between the knowledge-attitude, knowledge-practice, and attitude-practice. RESULTS: A response rate of rate of 90.22% (406 out of 452) was obtained. The mean scores of knowledge, attitude and practice were 10.61 +/- 1.19, 50.54 +/- 7.53 and 8.50 +/- 2.14 respectively. Spearman's correlation test revealed a significant linear positive correlation between knowledge and attitude (r-0.501, P- 0.01), knowledge and practice (r 0.185, P-0.01) and attitude and practice (r-0.351, P- 0.01) of DHPs about airborne isolation precautions. CONCLUSIONS: Dental health professionals considered in the present study showed good knowledge, positive attitude and good practice towards droplet and airborne isolation precautions during outbreak of MERS. Key words:Knowledge, attitude, practice, droplet, airborne, precaution, dental professionals. PMID- 27703607 TI - Assessment of non-carious root surface defects in areas of gingival recession: A descriptive study. AB - BACKGROUND: The purpose of this descriptive study was to observe the distribution of four different classes of non-carious cervical root surface discrepancies in teeth with gingival recession. Additionally to explore the different treatment modalities in the literature for each of these defects. MATERIAL AND METHODS: A total of 150 subjects with at least one labial gingival recession were included in the study. 1400 teeth were evaluated using 2.5 X magnification loupes and UNC 15 probe for the presence of the cemento-enamel junction and step like defects according to Pini-Prato's classification: A-, identifiable CEJ without defect; A+, identifiable CEJ with defect; B-, unidentifiable CEJ without defect, B+, unidentifiable CEJ with defect. Further a comprehensive electronic and hand search of pubmed indexed journals was performed to identify appropriate treatment modalities for these defects and their predictability following restorative/surgical or combination of both. RESULTS: A total of 1400 teeth with exposed root surfaces were examined (793 Maxillary; 607 mandibular). 499 teeth were A-, 405 were A+, 322 were B+ and 174 were B-. The distribution of these defects in different teeth was: 36% premolars, 32% molars, 21% incisors and 11% canines, collectively 68% in the aesthetic zone. CONCLUSIONS: Majority of these lesions are in the maxillary aesthetic zone. Hence the presence of the CEJ and the defect must be taken into account while managing these defects surgically. Key words:Cervical abrasion, gingival recession, magnification loupes, root coverage, step defects. PMID- 27703606 TI - In vitro histological evaluation of the surgical margins made by different laser wavelengths in tongue tissues. AB - BACKGROUND: Lasers have become standard tools for the surgical treatment of oral lesions. The purpose of this study is to determine the surgical margins and histologically evaluate the tissue thermal effects induced by different types of surgical instruments. MATERIAL AND METHODS: Cuts were made in pork tongues' mucosa with different lasers (Er:YAG at 2W with and without air / water spray and at 4W with and without air / water spray; CO2 at 3.5W and 7W in pulsed mode and at 7W in continuous mode; the diode laser at 3.5W and boost 3.5W in pulsed mode; Nd:YAG at 6W, 40Hz and electroscalpel at 5W and conventional scalpel as control. Macroscopic and microscopic morphological changes were evaluated. RESULTS: The results of this study showed that the surgical instruments that caused greater tissue damage extension were: the Nd:YAG laser (670.68MUm), the diode 3.5W and boost PW (626.82MUm), the CO2 7W CW (571.18MUm), the CO2 at 7W PW (485.45MUm), the diode 3.5W PW (456.15MUm), the electroscalpel (409.57MUm) and lastly the CO2 laser 3.5W PW (306.19MUm) and Er:YAG (74.66MUm) laser, regardless of power, mode or air / water spray used. An association between the Tissue Damage Extension and the Degree of Carbonization (r = 0.789; P = 0.01), and an association between the Tissue Damage Extension and Regularity of the Incision were found (r = -, 299; P = 0.01). CONCLUSIONS: The results of this study suggest that lasers can be used in soft tissues biopsies of the oral cavity, enabling a correct histopathological analysis, as long as the biological effects of each laser type are considered. The Er:YAG laser revealed its potential for biopsies of the oral mucosa ensuring a successful histological evaluation and the CO2 laser at 3,5W in pulsed mode presented itself as the best choice for surgeries with hemostasis.

PMID- 27703608 TI - Arch width changes in patients with Class II division 1 malocclusion treated with maxillary first premolar extraction and non-extraction method. AB - BACKGROUND: The aim of this study was to determine arch width changes during maxillary first premolars extraction and non-extraction treatment in patients with Class II division 1 malocclusion. MATERIAL AND METHODS: Dental casts of 91 Class II division 1 patients (36 males and 55 females) were evaluated. The minimum age of the subjects at the beginning of treatment was above 16 years. 48 patients were treated with extraction of the maxillary first premolars and 43 patients were treated without extraction. Pre- and post-treatment maxillary and mandibular inter-canine and inter-molar arch widths were measured. RESULTS: At the end of treatment, maxillary and mandibular inter-canine widths of both groups increased significantly. The maxillary inter-molar width decreased in the extraction group and increased in the non-extraction group. The mandibular inter molar width increased significantly in both groups. No significant differences were observed between males and females. CONCLUSIONS: The results of this study indicated that there was a tendency for an increase in arch width during both the extraction and non-extraction treatment except maxillary inter-molar width in the extraction cases.

AB - BACKGROUND: Evaluate the influence of different hybridization bonding techniques of a self-adhesive resin cement. MATERIAL AND METHODS: 30 human health molars were divided into six groups (n=10). The specimens received three longitudinal sections, allowing insertion of central cuts in PVC matrices. Each group received a different dentin pretreatment according to the manufacturer's recommendations, except the control group (G1), as follows. G2 - a 3-step total-etch adhesive system (OptibondTM FL, Kerr); G3 - a 3-step total-etch adhesive system (AdperTM ScotchbondTM Multi-Purpose, 3M ESPE); G4 - a 2-step total-etch adhesive system (AdperTM Single Bond 2, 3M ESPE); G5 - a single-step self-etching system (Bond Force, Tokuyama); and G6 - universal bonding system (Single Bond Universal, 3M ESPE). Then, cylinders made of self-adhesive resin cement with polypropylene matrix was cemented in all groups (RelyX U200, 3M ESPE). Bond strength was assessed by submitting the specimens to micro-shear test and was characterized according to the fracture pattern observed through optical microscopy. RESULTS: The results were submitted to the Kruskal-Wallis test, which indicated a statistically significant difference between the groups (p=0.04), and Tukey's multiple comparisons, which indicated a statistically significant difference between G1 and G3 (p<0.05). The microscopic analysis revealed a high prevalence of adhesive failures, followed by mixed fractures, and cohesive failures in the dentin. CONCLUSIONS: The use of a previous dentin hybridization protocol is able to increase adhesive bonding resistance of self-adhesive resin cement, especially when used AdperTM ScotchbondTM Multi-Purpose system.

AB - BACKGROUND: Silver has a long history of use in medicine as an antimicrobial and anti-inflammatory agent. Silver nanoparticles (NAg) offer the possibility to control the formation oral biofilms through the use of nanoparticles with biocidal, anti-adhesive, and delivery abilities. This study aims to evaluate the antibacterial effect of resin luting cements with and without NAg, and their influence on color, sorption and solubility. MATERIAL AND METHODS: NAg were incorporated to two dual-cured resin cements (RelyX ARC (RA) color A1 and RelyX U200 (RU) color A2) in two concentrations (0.05% and 0.07%, in weight), obtaining six experimental groups. Disc specimens (1x6mm) were obtained to verify the antibacterial effect against Streptococcus mutans in BHI broth after immersion for 1min, 5min, 1h, 6h, and 24h (n=3), through optical density readings. Specimens were evaluated for color changes after addition of NAg with a spectrophotometer (n=10). Sorption and solubility tests were also performed, considering storage in water or 75% ethanol for 28 days (n=5), according to ISO 4049:2010. Data were subjected to statistical analysis with ANOVA and Tukey (p=0.05). RESULTS: The optical density of the culture broths indicated bacterial growth, with and without NAg. NAg produced significant color change on the resin cements, especially in RA. Solubility values were very low for all groups, while sorption values raised with NAg. The cements with NAg did not show antibacterial activity against S. mutans. They also showed perceptible color change and higher sorption than the materials without NAg. CONCLUSIONS: The resin luting cements with NAg addition did not show antibacterial activity against SS. mutans. They also showed perceptible color change and higher sorption than the materials without NAg. Key words:Silver, resin cements, products with antimicrobial action, solubility, color perception tests. PMID- 27703611 TI - Are different generations of CAD/CAM milling machines capable to produce restorations with similar quality? AB - BACKGROUND: Different CAD/CAM machines' generation may impact the restoration overall quality. The present study evaluated the marginal fit of CAD/CAM restorations manufactured with different generations of CEREC milling unit systems. MATERIAL AND METHODS: Sixteen typodont teeth were divided into two groups (n=8) according to the machine's generation assigned. These are control group (G1): Cerec AC with Bluecam/Cerec 3 milling unit and (G2): Cerec AC with Bluecam/MC XL Premium Package milling unit. Scanning of the preparation were performed and crowns were milled using the Vita Mark II blocks. Blocks were cemented using epoxy glue on the pulpal floor only and finger pressure applied for 1 min. Upon completion of the cementation step, misfits between the restoration and abutment were measured by microphotography and the silicone replica technique using light body silicon material on Mesial (M) and Distal (D) surfaces. RESULTS: Mean and SDs of marginal gaps in micrometers were: G1/M: 94.90 (+/-38.52), G1/D: 88.53 (+/-44.87), G2/M: 85.65 (+/-29.89), G2/D: 95.28 (+/ 28.13). Two-way ANOVA indicated no significant differences among different groups (P>0.05); surface area (P>0.05) and the interaction (P>0.05). Overall, G2 had greater margin gaps than G1, however, without statistical difference (P>0.05). CONCLUSIONS: Difference in milling unit generation did not significantly affect the marginal fit. Marginal gap means were in the range of the clinical acceptance levels for both generations of Cerec milling units, regardless the teeth site area. Key words:CAD/CAM, margin, ceramics. PMID- 27703613 TI - In vitro comparison of passive and continuous ultrasonic irrigation in curved root canals. AB - BACKGROUND: The efficacy of endodontic irrigation procedures can be compromised by the complexity of the root canal system. Delivering irrigants to the apical third of curved canals presents a particular challenge to endodontists. This study compared the effects of two ultrasonic irrigation techniques on the penetration of sodium hypochlorite into the main canal and simulated lateral canals of curved roots in extracted teeth. MATERIAL AND METHODS: Two sets of simulated lateral canals were created at 2, 4, and 6 mm from the working length in 60 single-rooted teeth (6 canals/tooth, n = 360 canals). The teeth were randomly divided into three experimental irrigation groups: group 1 (n = 20), positive pressure irrigation (PPI); group 2 (n = 20), passive ultrasonic irrigation (PUI); and group 3 (n = 20), continuous ultrasonic irrigation (CUI). To assess the irrigation solution penetration, 20% Chinese ink (Sanford Rotring GmbH, Hamburg, Germany) was added to a 5% sodium hypochlorite solution and delivered into the curved root canals. The penetration of contrast solution into the simulated lateral canals was scored by counting the number of lateral canals (0-2) penetrated to at least 50% of the total length. RESULTS: The CUI group showed significantly higher (P < 0.05) irrigant penetration into the lateral canals and into the apical third of the main canals. The PPI group showed significantly lower sodium hypochlorite penetration (P < 0.001) into the main and lateral canals compared with that in the CUI and PUI groups. Significantly higher irrigant penetration was observed in the PUI group than the PPI group. CONCLUSIONS: Using CUI as the final rinse significantly increased the penetration of irrigant solution into the simulated lateral canals and apical third of curved roots.

AB - BACKGROUND: This study explores the pattern of complications occurrence resulting from traumatic dental injuries, the relation of this pattern to the number of years from the time of the injury to its first diagnosis, and other contributing characteristics such as root development and trauma characteristic. MATERIAL AND METHODS: Patients' data treated following dental trauma from 2002 to 2014 were classified and grouped according to age, gender, tooth type, injury type, diagnosis and the time that elapsed between the traumatic event and the diagnosis of complications (TIC). The distribution function of the quantitative parameters was determined with the Kolmogorov-Smirnov test. Fisher exact test was used to test differences between categorical parameters. RESULTS: The review identified 166 patients (114 male and 52 female), with a total of 287 traumatized teeth, and a mean of 1.8 injured teeth per incident. Maxillary teeth were involved significantly more often in traumatic dental injuries. The follow-up period range (TIC) had a mean of 2.99 years. The most frequent complication was pulp necrosis (34.2%). The most frequent complication related to avulsion was ankylotic root resorption (50%) diagnosed after a median TIC of 1.18 years. Open apices at the occurrence of trauma were observed in 52 teeth. Of these, 54.9% experienced pulp necrosis and 9.8% inflammatory root resorption with a median TIC of 1.63 years. Teeth that experienced multiple traumatic events showed significantly more late pulp necrosis compared to teeth that experienced a single traumatic injury (61.9% vs. 25.3%, respectively, p<0.0001). CONCLUSIONS: Follow-up periods should be based on the type of traumatic dental injury and the severity of the potential complications for the tooth. Current recommendations for follow-up after traumatic dental injury should be revised to reflect the need for more frequent and overall prolonged follow-up. Key words:Dental trauma, avulsion, open apex, pulp necrosis, root resorption, follow-up, complications.

AB - BACKGROUND: With introduction of many herbal medicines, dentistry has recently evidenced shift of approach for treating many inflammatory oral diseases by using such modalities. Aloe vera is one such product exhibiting multiple benefits and has gained considerable importance in clinical research recently. AIM: To compare the efficacy of Aloevera and Chlorhexidine mouthwash on Periodontal Health. MATERIAL AND METHODS: Thirty days randomized controlled trial was conducted among 390 dental students. The students were randomized into two intervention groups namely Aloe Vera (AV) chlorhexidine group (CHX) and one control (placebo) group. Plaque index and gingival index was recorded for each participant at baseline, 15 days and 30 days. The findings were than statistically analyzed, ANOVA and Post Hoc test were used. RESULTS: There was significant reduction (p<0.05) in the mean scores of all the parameters with Aloe Vera (AV) and chlorhexidine group. Post hoc test showed significant difference (p<0.000) in mean plaque and gingival index scores of aloe Vera and placebo and chlorhexidine and placebo group. No significant difference (p<0.05) was observed between AloeVera and chlorhexidine group. CONCLUSIONS: Being an herbal product AloeVera has shown equal effectiveness as Chlorhexidine. Hence can be used as an alternative product for curing and preventing gingivitis. Key words:Aloe vera, chlorhexidine, dental plaque, gingivitis.

AB - OBJECTIVES: To determine the diagnostic value of diascopy and other non-invasive clinical aids on recent differential diagnosis algorithms of oral mucosal pigmentations affecting subjects of any age. MATERIAL AND METHODS: Data Sources: this systematic review was conducted by searching PubMed, Scopus, Dentistry & Oral Sciences Source and the Cochrane Library (2000-2015); Study Selection: two reviewers independently selected all types of English articles describing differential diagnosis algorithms of oral pigmentations and checked the references of finally included papers; Data Extraction: one reviewer performed the data extraction and quality assessment based on previously defined fields while the other reviewer checked their validity. RESULTS: Data Synthesis: eight narrative reviews and one single case report met the inclusion criteria. Diascopy was used on six algorithms (66.67%) and X-ray was included once (11.11%; 44.44% with text mentions); these were considered helpful tools in the diagnosis of intravascular and exogenous pigmentations, respectively. Surface rubbing was described once in the text (11.11%). CONCLUSIONS: Diascopy was the most applied method followed by X-ray and surface rubbing. The limited scope of these procedures only makes them useful when a positive result is obtained, turning biopsy into the most recommended technique when diagnosis cannot be established on clinical grounds alone.

In fact, every day more and more surgeons are choosing dental implants for allowing great results in the field of oral rehabilitation. However, these procedures are not exempt from complications. This report presents the case of a 66 years old man underwent implant surgery by a specialized dentist. No problems were reported during implant placement. Despite this, three months later, it was displaced into the sublingual space at the time of uncovering. Against this backdrop, the patient was referred to an expert maxillofacial surgeon. Next day, the implant was removed using an intraoral approach to reach the sublingual space. According with our knowledge, there are no cases reported in the literature that describe this complication. Key words:Dental implant, sublingual space, bone atrophy, complications of oral surgery. PMID- 27703617 TI - Stunted root development: A rare dental complication of Stevens-Johnson syndrome. AB - Stevens-Johnson syndrome (SJS) is a severe cutaneous reaction seen rarely in clinical practice. Most often, it occurs as an adverse reaction to certain drugs. When it affects children at a very young age, arrested tooth root development may also be seen. We present a case of a 13 year old boy who suffered from SJ syndrome at the age of 7 years. Incomplete root development was observed in all teeth, as demonstrated by panaromic radiography. Clinical features of this condition and its management are further discussed. We aim to emphasise on the need for dental practitioners to be aware of the potential dental complications of SJS and enable them to recognise and manage the condition at the earliest so as to avoid any undesirable sequelae. Key words:Adverse drug reaction, amoxycillin, arrested root development, Stevens-Johnson syndrome. PMID- 27703618 TI - Mandibular destructive radiolucent lesion: The first sign of multiple myeloma. AB - The occurrence of a mandibular lesion as the first sign of multiple myeloma (MM) is uncommon. This report describes a case of MM diagnosed because of a mandibular lesion. A 62-year-old woman presented a destructive radiolucent lesion in the right mandibular ramus. The lesion caused rupture of the anterior cortical bone and extended from the retromolar area to the coronoid process. An incisional biopsy was performed. Histopathological examination revealed numerous pleomorphic plasma cells, some with binucleated nuclei. The tumor cells showed kappa light chain restriction. Bone marrow biopsy showed findings of massive infiltration of neoplastic plasma cells, besides lesions in the vertebrae. The diagnosis of MM was established. The patient underwent autologous hematopoietic stem-cell transplantation. Currently, the patient is under regular follow up after 40 months of initial treatment. In conclusion, MM should be considered in the differential diagnosis of destructive mandibular lesions. Key words:Mandible, multiple myeloma, radiolucent lesion. PMID- 27703619 TI - Meningitis and subdural empyema as complication of pterygomandibular space abscess upon tooth extraction. AB - Complication of dental infections might be various and heterogeneous. The most common complications are represented by maxilar celulitis, canine space celulitis, infratemporal space celulitis, temporal celulitis and bacteremia. Among rarest complications we found: sepsis, bacterial endocarditis, mediastinitis, intracranial complications, osteomyelitis, etc. Although dental infections are often considered trivial entities, sometimes they can reach an impressive gravity. In this regard, the present study describes a case of dental infection complicated by meningitis, subdural empiema and cerebral vasculitis. Furthermore, we observed other neurological complications, like thalamic ischemic infarction, during the disease evolution. Noteworthy, these entities were not presented when the patient was admitted to hospital. Therefore, the main aim of this report is to highlight the serious consequences that an infection of dental origin could cause. Key words:Meningitis, subdural empyema, odontogenic infections.

AB - Cowden's Syndrome (CS) is a rare congenital autosomal dominant disorder that affects around 1/200000 patients with an incomplete penetrance and variable expressivity, characterized by alterations in a tumor suppressor gene. A 14-year old Caucasian male patient came to the attention of the authors complaining of palm nodules, gingival bleeding and painful pedunculated lesions on the lips and on the labial side of anterior sextants. After genetic investigation the final diagnosis of a Cowden Syndrome was made. The lesions were surgically removed under general anesthesia and no clinical signs of recurrence were found three months after surgical excision. Considering the severe symptoms of the syndrome and the strong tendency to malignant development of the associated lesions all clinicians should focus their efforts to the early diagnosis and, when possible, multidisciplinary treatment.

PMID- 27703622 TI - A first step toward understanding patient safety. AB - Patient safety has become an important policy agenda in healthcare systems since publication of the 1999 report entitled "To Err Is Human." The paradigm has changed from blaming the individual for the error to identifying the weakness in the system that led to the adverse events. Anesthesia is one of the first healthcare specialties to adopt techniques and lessons from the aviation industry. The widespread use of simulation programs and the application of human factors engineering to clinical practice are the influences of the aviation industry. Despite holding relatively advanced medical technology and comparable safety records, the Korean health industry has little understanding of the systems approach to patient safety. Because implementation of the existing system and program requires time, dedication, and financial support, the Korean healthcare industry is in urgent need of developing patient safety policies and putting them into practice to improve patient safety before it is too late. PMID- 27703623 TI - How to understand and conduct evidence-based medicine. AB - Evidence-based medicine (EBM) is the conscientious, explicit, and judicious use of current best evidence in making decisions regarding the care of individual patients. This concept has gained popularity recently, and its applications have been steadily expanding. Nowadays, the term "evidence-based" is used in numerous situations and conditions, such as evidence-based medicine, evidence-based practice, evidence-based health care, evidence-based social work, evidence-based policy, and evidence-based education. However, many anesthesiologists and their colleagues have not previously been accustomed to utilizing EBM, and they have experienced difficulty in understanding and applying the techniques of EBM to their practice. In this article, the author discusses the brief history, definition, methods, and limitations of EBM. As EBM also involves making use of the best available information to answer questions in clinical practice, the author emphasizes the process of performing evidence-based medicine: generate the clinical question, find the best evidence, perform critical appraisal, apply the evidence, and then evaluate. Levels of evidence and strength of recommendation were also explained. The author expects that this article may be of assistance to readers in understanding, conducting, and evaluating EBM. PMID- 27703624 TI - Dexmedetomidine combined with midazolam vs. dexmedetomidine alone for sedation during spinal anesthesia. AB - BACKGROUND: Dexmedetomidine is a useful sedative agent for spinal anesthesia. However, it has been reported that dexmedetomidine decreases heart rate in a dose dependent manner. In the current study, we compared the administration of a bolus dose of midazolam and bolus loading of dexmedetomidine over 10 min with the goal of identifying an additional method of sedation. METHODS: Ninety patients classified as American Society of Anesthesiologists physical status I-II who were undergoing spinal anesthesia were divided into two groups. In the midazolam and dexmedetomidine combined group (group MD), 10 min after bolus loading of 0.05 mg/kg midazolam, 0.5 ug/kg/h dexmedetomidine was continuously infused. In the dexmedetomidine group (group D), 1 ug/kg dexmedetomidine was infused over 10 min, and then 0.5 ug/kg/h dexmedetomidine was continuously infused. RESULTS: At 10 min, the sedation depth of the two groups was almost equal. In both groups, the bispectral index was within the optimal score range of 55-80 and the Ramsay Sedation Scale score was within the optimal range of 3-5. Satisfaction with sedation for both patient and surgeon did not differ between the two groups. At 10 min, heart rate was significantly lower (P < 0.010) in group D and mean blood pressure was significantly lower (P < 0.010) in group MD. The prevalence of bradycardia, hypotension, and hypoxia did not differ statistically between the two groups (P = 0.714, P = 0.089, P = 0.495, respectively). CONCLUSIONS: Midazolam bolus and dexmedetomidine continuous infusion (the regimen of group MD) may be an additional sedation method for patients who have severe bradycardia. PMID- 27703625 TI - Effective doses of cisatracurium in the adult and the elderly. AB - BACKGROUND: There are few information about the differences of the effective dose (ED) of cisatracurium between the adult and the elderly. We investigated the ED and the onset time of cisatracurium in the adults and the elderly. METHODS: We studied two hundred patients of the adults aged 20 through 64 years and the elderly aged >= 65 years, with American Society of Anesthesiologists physical status I or II. Each 100 patients with 20 patients of each dose group, randomly selected from 30, 40, 50, 60 or 70 ug/kg of cisatracurium, were randomly allocated to the adults and the elderly groups. We recorded the 0.1 Hz single twitch responses of the adductor pollicis and the onset times to maximal blockade. The magnitude of muscle relaxation was recorded by using an acceleromyography. The effect of cisatracurium on single twitch was calculated as percent reduction. After converting each drug dose into logarithm and percent reduction of the muscle reduction into probit, the EDs representing the muscle relaxation effects of 5%, 25%, 50%, 75% and 95% were estimated using the linear regression analysis. RESULTS: No significant differences were found in age, weight, height, or body mass index within or between the groups. The ED50 and ED95 of the adult group were 35.39 and 59.58 ug/kg. The ED50 and ED95 of the elderly group were 34.89 and 55.50 ug/kg, respectively. The onset times were 375.4 +/- 76.9 seconds in the adult group and 369.1 +/- 70.0 seconds in the elderly group. CONCLUSIONS: The ED and the onset time were not significantly different between the adult and the elderly. PMID- 27703626 TI - Impact of hydroxyethyl starch 70/0.5 on acute kidney injury after gastroenterological surgery. AB - BACKGROUND: Previous studies reported a higher mortality risk and a greater need for renal replacement therapy in patients administered hydroxyethyl starch (HES) rather than other fluid resuscitation preparations. In this study, we investigated the association between 6% HES 70/0.5 use and postoperative acute kidney injury (AKI) in gastroenterological surgery patients. METHODS: We conducted retrospective full-cohort and propensity-score-based analyses of patients who underwent gastroenterological surgery between June 2011 and August 2013 in a Japanese university hospital. The study sample comprised 66 AKI and 2,152 non-AKI patients in the full-cohort analysis and 35 AKI and 1,269 non-AKI patients in the propensity-score-based analysis. Propensity scores were calculated using an ordered logistic regression model in which the dependent variable comprised three groups based on HES infusion volumes (0, 1-999, and >= 1,000 ml). The association between HES groups and postoperative AKI incidence was analyzed using multiple logistic regression models. Other candidate independent variables included patient characteristics and intraoperative measures. RESULTS: In the full-cohort analysis, 40 (60.6%) AKI patients were diagnosed as "risk", 15 (22.7%) as "injury," and 11 (16.7%) as "failure". In the propensity-score-based analysis, the corresponding values were 22 (62.9%), 8 (22.9%), and 5 (14.3%). There was no significant association between total infused HES and postoperative AKI incidence in either the full-cohort or the propensity-score-based analysis (P = 0.168 and P = 0.42, respectively). CONCLUSIONS: AKI incidence was not associated with clinical 6% HES 70/0.5 administration in gastroenterological surgery patients treated at a single center. PMID- 27703627 TI - Pretreatmet with 5% lidocaine patch reduces cannula-induced and propofol-induced pain: a randomized, double-blind, placebo-controlled study. AB - BACKGROUND: The purpose of this study was to determine the efficacy of 5% lidocaine patch in reducing propofol-induced pain and cannula-induced pain. METHODS: In a randomized, double-blind study, 126 patients were divided into one of three groups: pretreatment with a 5% lidocaine patch (Lidotop(r)) and premixed 2 ml of normal saline with 1.5 mg/kg of 1% propofol (Group A); pretreatment with a placebo patch and premixed 2 ml of normal saline with 1.5 mg/kg of 1% propofol (Group B); or pretreatment with a placebo patch and premixed 2 ml of 2% lidocaine (40 mg) with 1.5 mg/kg of 1% propofol (Group C) for induction of anesthesia. Pain severity was evaluated on a four-point verbal rating scale during intravenous cannulation, propofol injection, and 24 h after the operation (recall). RESULTS: Eighteen patients (47.4%) in Group A complained of cannula-induced pain compared with 35 (94.6%) in Group B and 36 (94.7%) in Group C (P < 0.001). Group A patients showed significantly lower incidence of propofol-induced pain and recall of propofol-induced pain compared with Group B (P < 0.001 and P = 0.01), whereas there was no difference compared with Group C. CONCLUSIONS: Preoperative transdermal administration of 5% lidocaine patch is an effective and simple method in reducing propofol-induced pain as well as cannula-induced pain. PMID- 27703628 TI - Ultrasound measurement of the vertebral level of Tuffier's line in elderly women. AB - BACKGROUND: It would be imprecise to generalize the vertebral level determined by palpation to patients of all ages. The purpose of this study was to compare the vertebral level passed by Tuffier's line in elderly women with that passed in adult women using ultrasound in the left lateral decubitus flexed position. METHODS: We enrolled 50 female patients over the age of 65 (elderly group) and 50 female patients between ages 20 and 50 (control group) who had been scheduled to undergo spinal anesthesia. Using ultrasound, we marked the L2-5 lumbar spinous processes and intervertebral spaces. The most cephalad part was labeled 1 and the most caudal part was labeled 11. We then identified which line of these vertebral levels Tuffier's line crossed. RESULTS: The median value of the numbers signifying the vertebral level of Tuffier's line was 3 (the L2-3 intervertebral space) in the elderly group, while it was 8 (the lower part of the L4 vertebra) in the control group. The vertebral level of Tuffier's line had statistically significant correlations with age, body mass index, and weight in the elderly group (P < 0.001). CONCLUSIONS: The vertebral level of Tuffier's line determined with ultrasound measurement in the left lateral decubitus flexed position was more cephalad in the elderly women than in those of the control group. Therefore, we should consider that the needle could be inserted at a higher level than expected, and use care in determining the level of needle insertion during spinal anesthesia in elderly women. PMID- 27703629 TI - Comparison of effects of intraoperative nefopam and ketamine infusion on managing postoperative pain after laparoscopic cholecystectomy administered remifentanil. AB - BACKGROUND: Although intraoperative opioids provide more comfortable anesthesia and reduce the use of postoperative analgesics, it may cause opioid induced hyperalgesia (OIH). OIH is an increased pain response to opioids and it may be associated with N-methyl-D-aspartate (NMDA) receptor. This study aimed to determine whether intraoperative nefopam or ketamine, known being related on NMDA receptor, affects postoperative pain and OIH after continuous infusion of intraoperative remifentanil. METHODS: Fifty-four patients undergoing laparoscopic cholecystectomy were randomized into three groups. In the nefopam group (N group), patients received nefopam 0.3 mg/kg at the induction of anesthesia followed by a continuous infusion of 0.065 mg/kg/h. In the ketamine group (K group), patients received ketamine 0.3 mg/kg at the induction of anesthesia followed by a continuous infusion of 3 ug/kg/min. The control group did not received any other agents except for the standard anesthetic regimen. Postoperative pain score, first time and number of demanding rescue analgesia, OIH and degrees of drowsiness/sedation scale were examined. RESULTS: Co administrated nefopam or ketamine significantly reduced the total amount of intraoperative remifentanil and postoperative supplemental morphine. Nefopam group showed superior property over control and ketamine group in the postoperative VAS score and recovery index (alertness and respiratory drive), respectively. Nefopam group showed lower morphine consumption than ketamine group, but not significant. CONCLUSIONS: Both nefopam and ketamine infusion may be useful in managing in postoperative pain control under concomitant infusion of remifentanil. However, nefopam may be preferred to ketamine in terms of sedation. PMID- 27703630 TI - Operation room management in Korea: results of a survey. AB - BACKGROUND: The current state of general hospital operation room (OR) in Korea and how these ORs are being operated remain unclear. Therefore, the aim of this study was to investigate and assess the current state of OR management and surgical scheduling in general hospitals of Korea. METHODS: A total of 92 anesthesiology training hospitals and 2 equivalent hospitals in Korea were targeted for the survey. Anesthesiologists in hospitals received questionnaires for OR, anesthetic managements and surgical scheduling directly or by phone from the beginning of October 2015 to the end of December 2015. RESULTS: Of the 94 hospitals that were targeted, 59 hospitals (62.7%) responded to the survey. Of the 59 hospitals, 40 (67.8%) had 500-1,000 beds, 36 (61.0%) had 11-20 ORs. Most OR arrangements were made by residents and specialists in Anesthesiology Department (90%). Most hospitals (47.4%) in the response set performed total surgeries in the range of 10,000 to 20,000 annually. The proportion of emergency surgeries in the total surgeries was 2.8-55.0%. Methods for predicting expected surgery time were arbitrarily decided by surgeons (61%), anesthesiologist's experience (20%), or by analyzing historical data using software (5%). CONCLUSIONS: This survey study could trigger active operational researches for OR efficiency. It might help hospital policy makers manage OR resources more efficiently. PMID- 27703632 TI - A comparison of strength for two continuous peripheral nerve block catheter dressings. AB - BACKGROUND: Despite the benefits of continuous peripheral nerve blocks, catheter dislodgment remains a major problem, especially in the ambulatory setting. However, catheter dressing techniques to prevent such dislodgment have not been studied rigorously. We designed this simulation study to test the strength of two commercially available catheter dressings. METHODS: Using a cadaver model, we randomly assigned 20 trials to one of two dressing techniques applied to the lateral thigh: 1) clear adhesive dressing alone, or 2) clear adhesive dressing with an anchoring device. Using a digital luggage scale attached to a loop secured by the dressing, the same investigator applied steadily increasing force with a downward trajectory towards the floor until the dressing was removed or otherwise disrupted. RESULTS: The weight, measured (median [10th-90th percentile]) at the time of dressing disruption or removal, was 1.5 kg (1.3-1.8 kg) with no anchoring device versus 4.9 kg (3.7-6.5 kg) when the dressing included an anchoring device (P < 0.001). CONCLUSIONS: Based on this simulation study, using an anchoring device may help prevent perineural catheter dislodgement and therefore premature disruption of continuous nerve block analgesia. PMID- 27703631 TI - Development of the Geop-Pain questionnaire for multidisciplinary assessment of pain sensitivity. AB - BACKGROUND: To assess the multidisciplinary aspects of pain, various self-rating questionnaires have been developed, but there have not been sufficient relevant studies on this topic in South Korea. The aim of this study was to develop a new pain sensitivity-related questionnaire in the Korean language that would be simple and would well reflect Koreans' senses. METHODS: A new pain assessment questionnaire was developed through a pre-survey on "geop", which is the Korean word expressing fear, anxiety, or catastrophizing. We named the new assessment questionnaire the Geop-Pain Questionnaire (GPQ). The GPQ was composed of 15 items divided into three categories and rated on a 5-point scale. As a preliminary study, internal consistency and test-retest reliability analyses were conducted. Subsequently, 109 individuals completed the GPQ along with three pain-related questionnaires translated into Korean (Pain Sensitivity Questionnaire [PSQ], Pain Anxiety Symptoms Scale [PASS], and Pain Catastrophizing Scale [PCS]), and the correlations were analyzed. RESULTS: All items in the GPQ showed appropriate internal consistency, and the test-retest reliability analysis showed no statistically significant differences. The correlations between the GPQ and the existing questionnaires revealed that the GPQ scores had mid-positive correlations with the PSQ scores and strong positive correlations with the PASS and PCS scores. CONCLUSIONS: This study attempted to develop a questionnaire assessing pain sensitivity multidimensionally using the Korean word geop for the first time. The self-rating GPQ showed high correlations with the existing questionnaires and demonstrated potential to be utilized as a pain prediction index in clinical practice. PMID- 27703633 TI - Anaphylactic shock caused by intramuscular injection of midazolam during the perioperative period: a case report. AB - Although anaphylactic shock during the perioperative period is rare, it can be lethal due to severe cardiovascular and respiratory collapse. Midazolam is generally used as premedication for relieving anxiety about the operation, and the danger of anaphylactic shock after intramuscular injection is not widely recognized. We report the first case of anaphylactic shock occurring during the perioperative period after intramuscular injection of midazolam. Since anaphylactic shock after intramuscular injection can be of slow onset, the operation should be delayed if an anaphylactic reaction is suspected, even if the symptoms are limited. In addition, anesthesiologists should be prepared for the occurrence of anaphylaxis at any time in the perioperative period. PMID- 27703634 TI - Cardiac arrest after sugammadex administration in a patient with variant angina: a case report. AB - A 76-year-old man with no notable medical history was scheduled for a robot assisted radical prostatectomy. After the operation, he was given sugammadex. Two minutes later, ventricular premature contraction bigeminy began, followed by cardiac arrest. Cardiac arrest occurred three times and cardiopulmonary resuscitation was done. The patient recovered after the third cardiopulmonary resuscitation and was transferred to the intensive care unit. Coronary angiography was done on postoperative day 1. The patient was diagnosed with variant angina and discharged uneventfully on postoperative day 8. PMID- 27703635 TI - Anesthetic management during surgery for left ventricular aneurysm and false aneurysm occurring in stage: a case report. AB - Left ventricular aneurysm (LVA) and false aneurysm are complications of acute myocardial infarction, trauma, and cardiac surgery. Left ventricular false aneurysm (LVFA) is a particularly catastrophic complication owing to its high propensity for rupture. Surgical resection should be considered for LVFA occurring within three months after myocardial infarction or development of congestive heart failure. In this report, we describe a case of acute heart failure with LVA and LVFA occurring in stage as a complication of myocardial infarction in a 55-year-old man. The patient was also at risk of brain ischemia due to abnormal vessel status and a previous cerebrovascular accident with left sided weakness. Successful perioperative anesthetic management was achieved by focusing on maintaining marginal upper normal blood pressure to ensure cerebral perfusion and to reduce the risk of false aneurysm rupture. PMID- 27703636 TI - Bronchoscopic concerns in Proteus syndrome: a case report. AB - Proteus syndrome (PS) is a rare congenital hamartomatous disorder with multisystem involvement. PS shows highly clinical variability due to overgrowth of the affected areas, and several features can make anesthetic management challenging. Little is known about the airway problem associated with anesthesia in PS patients. An 11-year-old girl with PS was scheduled for ear surgery under general anesthesia. She had features complicating intubation including facial asymmetry and disproportion, abnormal teeth, limitation of neck movement due to torticollis, and thoracolumbar scoliosis. This study reports on a case of deformed airway of a PS patient under fiberoptic bronchoscopy. PMID- 27703637 TI - Intracranial hemorrhage induced uncontrolled seizure in a deceased donor liver transplant patient: a case report. AB - Seizure is the second most common neurologic complication after liver transplantation and may be caused by metabolic abnormalities, electrolyte imbalance, infection, and immunosuppressant toxicity. A 61-year-old male patient underwent liver transplantation due to hepatitis B virus-related liver cirrhosis with portal systemic encephalopathy. The immediate postoperative course of the patient was uncomplicated. However, on postoperative day (POD) 6, weakness developed in both lower extremities. No abnormal findings were detected on a brain computed tomography (CT) scan on POD 8, but a generalized tonic clonic seizure developed which was difficult to control even with multiple antiepileptic drugs. A follow-up brain CT scan on POD 15 showed a 2.7 cm sized acute intracranial hemorrhage (ICH) in the left parietal lobe. The patient's mental status improved after 2 months and he was able to communicate through eye blinking or head shaking. Our case reports an acute ICH that manifested into a refractory seizure in a patient who underwent a liver transplant. PMID- 27703638 TI - Central venous catheter malposition due to dialysis catheter: a case report. AB - A 56-year-old man on maintenance hemodialysis was admitted to the intensive care unit with septic shock and coagulopathy. As there was a dialysis catheter in the right internal jugular vein, the left internal jugular vein was cannulated with a central venous catheter to initiate vasopressor therapy. A chest X-ray showed formation of a catheter loop inside the left brachiocephalic vein, probably due to hindrance by the dialysis catheter. This report describes the hurdles encountered, repeated cannulation attempts, and serial chest X-ray findings required to obtain acceptable placement of the catheter tip. PMID- 27703639 TI - Elaborate study design leads to improved conclusion. PMID- 27703640 TI - Evaluation of the Prevalence Rate and the Prognostic Effect of Human Papilloma Virus Infection in a Group of Patients With Oral Cavity Squamous Cell Carcinoma. AB - BACKGROUND: Squamous cell carcinoma (SCC) is the most common malignancy of the oral cavity. A relationship between the human papilloma virus (HPV) infection and the prognosis of oral cavity SCC (OCSCC) has been discussed before. OBJECTIVES: We investigated the prevalence rate of HPV status in patients with OCSCC, and its effects on clinicopathological characteristics of tumors and patients' prognosis. PATIENTS AND METHODS: Sections of formalin-fixed, paraffin-embedded tissue blocks from 114 histopathologically confirmed OCSCC cases were investigated in this study. Polymerase chain reaction (PCR) was applied to evaluate the HPV status in the samples. RESULTS: Fifteen (13.16%) cases were identified as HPV positive. The detected viral subtypes in this study were the subtypes 6 and 11. The stage and especially lymph node stage was significantly higher in the HPV positive group compared to the HPV negative group (P = 0.04). Disease free survival (DFS) was remarkably lower in the HPV positive group compared to the HPV negative group (13.9 vs. 49.9 months, P = 0.02). Overall survival (OS) was also significantly inferior in the HPV positive group (15.7 vs. 49.6 months, P = 0.01). In the current study, no significant differences were observed between two groups in relation to the variables of age, gender, tumors site, tumor size, tumor grading and also the recurrence rate. CONCLUSIONS: The observed higher mortality rate among the HPV positive group indicates the poorer prognosis of this group in comparison with the HPV negative patients. The incidence rate of HPV infection was low in the studied samples; however, interaction of subtypes 6 and 11 of HPV in poorer prognosis of the patients and a carcinogenic role of HPV in OCSCC cannot be ruled out. PMID- 27703641 TI - Iranian Nurses Perceptions of Cancer Patients Quality of Life. AB - BACKGROUND: Cancer is the third main cause of death in Iran only after cardiovascular diseases and accidents. OBJECTIVES: The main aim of this research study was to identify nurses' understanding of cancer patients' Quality of Life (QoL) in an Iranian context. PATIENTS AND METHODS: This descriptive correlational study was conducted in an educative referral oncology center affiliated to Isfahan University of Medical Sciences, Isfahan, Iran in 2013. 50 pairs of cancer patients and their nurses were conveniently recruited. The sample of nurses were selected based on consensus sampling which included more than 70 percent of eligible nurses in the hospital. Patients and nurses were requested to complete the Farsi version of the world health organization quality of life (WHOQoL-BREF) questionnaire, separately. QoL was measured across four dimensions including physical, psychological, social relationship and environmental. RESULTS: The QoL mean domain scores of patients were 10.06, 11.88, 12.76 and 11.96, respectively. The corresponding scores of nurses were 11.6, 11.23, 12.65 and 12.07. Pearson correlations between patients and nurses scores were 0.42, 0.5, 0.25 and 0.58 which revealed a fair to moderate agreement between nurses' and patients' scores in different domains. Paired samples t-test values indicated that physical QoL mean domain scores of patients were significantly lower than the corresponding drawings of nurses [t (49) = -3.41, P < 0.001]. CONCLUSIONS: The main finding of this QoL study was that nurses generally have a moderate understanding of cancer patients' QoL. Therefore, in order to meet different physio-psycho-social needs of patients, nurses must enhance their understanding of patients' QoL particularly in more subjective and personal domains like social domain using a holistic approach. PMID- 27703642 TI - Immunohistochemistry Study of P53 and C-erbB-2 Expression in Trophoblastic Tissue and Their Predictive Values in Diagnosing Malignant Progression of Simple Molar Pregnancy. AB - BACKGROUND: Finding a tumor marker to predict the aggressive behavior of molar pregnancy in early stages has yet been a topic for studies. OBJECTIVES: In this survey we planned to study patients with molar pregnancy to 1) assess the p53 and c-erbB-2 expression in trophoblastic tissue, 2) to study the relationship between their expression intensity and progression of a molar pregnancy to gestational trophoblastic neoplasia, and 3) to determine a cut off value for the amount of p53 and c-erbB-2 expression which might correlate with aggressive behavior of molar pregnancy. PATIENTS AND METHODS: In a prospective cross sectional study by using a high accuracy technique EnVision Tm system for immunohistochemistry staining of molar pregnancy samples, we evaluated p53 and c-erbB-2 expression in cytotrophoblast and syncytiotrophoblast and the correlation of their expression with progression of molar pregnancy to gestational trophoblastic neoplasia (GTN). Normal prostatic tissue and Breast cancer tissue were used as positive controls. RESULTS: We studied 28 patients with simple molar pregnancy (SMP) and 30 with GTN. Cytotrophobalst had significantly higher expression of p53 and c-erbB-2 and syncytiotrophoblast had greater expression of p53 in GTN group as compared to SMP group. The cut off values for percentage of p53 positive immunostained cytotrophoblast and syncytiotrophoblast were 5.5% and 2.5%. In c-erbB-2 positive membranous stained cytotrophoblast the cut off was 12.5%. CONCLUSIONS: Our data suggests that over expression of p53 and c-erbB-2 is associated with malignant progression of molar pregnancy. We encountered that high expression of p53 and c erbB-2 in trophoblastic cells could predict gestational trophoblastic neoplasia during the early stages. PMID- 27703643 TI - Stevens-Johnson Syndrome Patient Received Combination Chemotherapy Gemcitabine, Cisplatin, and 5-FU for Biliary Tract Cancer. AB - Stevens-Johnson syndrome has been an acute, usually self-limiting disease of the skin and mucous membranes. This case report has presented an evidence of the development Stevens - Johnson syndrome associated with combination chemotherapy administration of 5FU, gemcitabin and cisplatin in a patient with biliary tract cancer. Our case was a 54-year-old woman patient, a case of biliary tract cancer who has developed more severe symptoms of Stevens-Johnson syndrome. Diagnosis has confirmed by skin biopsy of an affected area .The patient has improved with supportive care, and during 25 day occurred recovery. Although Stevens-Johnson syndrome has been a rare toxicity, physicians should pay a special attention to the monitoring of biliary tract cancer patients on combination chemotherapy with 5FU, cisplatin and gemcitabin. PMID- 27703644 TI - Rhabdomyosarcoma of Cervix: A Case Report. AB - INTRODUCTION: Rhabdomyosarcoma has known as a highly malignant soft tissue sarcoma. It has been the most common soft tissue sarcoma in childhood, accounting for about 3 to 4 % of all cases of childhood cancer. Rhabdomyosarcoma was rare in adults, accounting for 3% of all soft-tissue sarcomas. embryonal rhabdomyosarcoma of female genital tract including uterine cervix in an adult was rare. CASE PRESENTATION: This study has reported a 33-year-old woman presented with abnormal vaginal discharge. Gynecologic examination revealed a cervical mass with grape- like feature protruding into vagina with posterior- superior vaginal wall involvement. Biopsy has performed and pathologic examination was consistent with embryonal botryoid type rhabdomyosarcoma. She has undergone the staging work up measurements including thoracic computed tomography (CT) scan, abdominopelvic magnetic resonance imaging (MRI), bone scan and bone marrow examination. In exception of abdominopelvic MRI, with 2 suspicious pelvic lymph nodes in addition of cervical mass, all others were normal. Radical hysterectomy with lymph node debulking and ovarian preservation has performed. Final results have shown embryonal botryoid type rhabdomyosarcoma of cervix. ovaries, endometrium, parametrium, and follopian tubes were unremarkable. Pelvic lymph nodes pathology and intraabdominal fluid cytology were negative for malignancy. Lymphovascular invasion was identified. She has advised for adjuvant chemotherapy. CONCLUSIONS: This case has reminded that embryonal rhabdomyosarcoma could occur in uncommon site and older female. Longer follow up of these cases has required due to lack of survival data for embryonal rhabdomyosarcoma of this site and age group. PMID- 27703645 TI - The Correlation of Plasma 25-Hydroxyvitamin D Deficiency With Risk of Breast Neoplasms: A Systematic Review. AB - CONTEXT: Breast cancer has been considered as one of the most common types of cancer among the women worldwide, and patients with breast neoplasms have been reported with high prevalence of low serum 25-hydroxyvitamin D levels. OBJECTIVES: Our aim was to evaluate the correlation of plasma 25-hydroxyvitamin D deficiency with breast neoplasms risk among women. DATA SOURCES: PubMed database was searched with MeSH (medical subject headings) keywords "vitamin D AND breast neoplasms" which was restricted by original articles written only in English and published from January 1, 2014. STUDY SELECTION: To find the articles that met eligibility criteria, titles and abstracts were examined. DATA EXTRACTION: This systematic review was conducted according to PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement. Critical appraising of evidence was performed, using the study quality assessment tools of national institutes of health, national heart, lung and blood institute (NHLBI). RESULTS: Overall, 76 potential articles were identified and after screening, 13 articles met eligible criteria for inclusion. Definition of low vitamin D levels varied greatly among studies, making comparisons difficult, but most of them have defined deficiency as 25(OH)D < 20 ng/mL. Evidence was mainly of fair quality. CONCLUSIONS: This study has provided evidence that vitamin D deficiency has been very prevalent in patients with breast neoplasms, more than comparable matched control population, and risk of breast cancer has increased with low vitamin D levels, suggesting the need for high quality studies that assessed the health consequences attributable to vitamin D deficiency employing standard definitions. PMID- 27703646 TI - Adenosine Deaminase Activity in Chronic Lymphocytic Leukemia and Healthy Subjects. AB - BACKGROUND: B cell chronic lymphocytic leukemia is one of the most frequent hematologic malignancies in the world. Cellular surface CD markers and serum Beta 2-microglobulin may be used as a prognostic tool in CLL patients. OBJECTIVES: In the present study we introduce serum adenosine deaminase as a diagnostic marker in CLL. MATERIALS AND METHODS: Blood samples were collected from B-CLL and healthy subjects. White blood cell, red blood cell and platelet count and blood Erythrocyte sedimentation rate was recorded and serum Beta-2-microglobulin, Lactate dehydrogenase and total ADA enzyme activity were determined. RESULTS: Serum ADA activity was significantly higher in patients group than that of controls. ADA had a significant and direct correlation with B2M, WBC, LDH and ESR. However, there was not any relation between ADA and the stages of disease. Diagnostic cut-off, sensitivity and specificity of the serum ADA test were 27.97 U/L, 91% and 94%, respectively. CONCLUSIONS: A higher ADA activity in patients group and its correlation with CLL markers were seen in our study. High diagnostic value of serum ADA in our study suggests that it might be considered as a useful screening tool among the other markers in CLL. PMID- 27703647 TI - The Prognostic Value of Age, Sex, and Subsite in Cutaneous Head and Neck Melanoma: A Clinical Review of Recent Literature. AB - CONTEXT: Cutaneous head and neck melanoma is a challenging disease owing to its aggressive nature and often times advanced stage at presentation. Age, sex, and subsite are three prognostic indicators which can be determined prior to treatment or testing, and can allow the practitioner to counsel the patient before initiating therapy. EVIDENCE ACQUISITION: A PubMed search was conducted utilizing various terms relating to the subject matter. Articles over the past 25 years were analyzed and appropriately selected for review. RESULTS: It appears that patients older than 65 have a decreased overall 5 year survival compared to their younger counterparts. Male patients have poorer prognosis compared to female patients as noted by the decreased overall survival, decreased disease specific survival, and shorter time to distant metastasis. Scalp subsite was most uniformly accepted as having the worst prognosis in the head and neck, and may even serve as an independent prognostic indicator. CONCLUSIONS: Advanced age, male sex, and scalp subsite all portend poor prognosis in patients with cutaneous head and neck melanoma. PMID- 27703648 TI - Lactobacilli Differentially Modulate mTOR and Wnt/ beta-Catenin Pathways in Different Cancer Cell Lines. AB - BACKGROUND: Lactobacilli are a group of beneficial bacteria whose anti cancer effects have been evaluated in different cancer cell lines as well as animal models and human subjects. Such anti cancer effects can be exerted via different mechanisms such as modulation of immune response as well as inhibition of pathogens colonization. In addition, lactobacilli have direct cytotoxic effects against cancer cells which may be exerted through modulation of expression cancer related pathways. OBJECTIVES: The aim of this study is to find the mechanism of anti cancer effects of two lactobacilli strains, Lactobacillus. crispatus (LC) and Lactobacillus. rhamnosus (LR). MATERIALS AND METHODS: We analyzed expression of some mTOR and Wnt/ beta-catenin pathways genes in three cancer cell lines (HeLa, MDA-MB-231 and HT-29) following treatment with LC and LR culture supernatants. RESULTS: Of note, the expression of CCND1 as a marker of cell proliferation, survival, and angiogenesis, has been decreased following LR treatment in all cell lines. In addition, the expression of SFRP2, an antagonist of Wnt pathway, has been increased in HT-29 following LR treatment and in HeLa cells following LR and LC treatments. Furthermore, we have demonstrated the downregulation of S6K1 expression, a marker of poor prognosis, following LR treatment in HT-29 and following LR and LC treatments in MDA-MB-231 cell line. CONCLUSIONS: Consequently, lactobacilli can modulate expression of mTOR and Wnt/ beta-catenin pathways genes in cancer cell lines in a strain specific as well as cell type specific manner. PMID- 27703649 TI - CT Simulation to Evaluate of Pelvic Lymph Node Coverage in Conventional Radiotherapy Fields Based on Bone and Vessels Landmarks in Prostate Cancer Patients. AB - BACKGROUND: Radiotherapy is the gold standard for treatment of prostrate cancer as it can cover an adequate area of tissues at risk for metastasis. OBJECTIVES: We evaluated the Pelvic lymph node coverage of conventional radiotherapy fields based on bone and vessels landmarks using computed tomography (CT) simulation in patients with prostate cancer referred to Shohada-e-Tajrish hospital. PATIENTS AND METHODS: In this cross sectional study, 40 patients with prostate cancer at the Stage T1c to T3b were studied. Pelvic lymph nodes were contoured by using pelvic vessels as surrogate markers. The distances were measured at different points of anterior-posterior (AP) and lateral fields and distances > 5 mm or more between the contoured nodes and the field borders. RESULTS: Mean and standard deviation of the aortic bifurcation from the superior border was 4.73 +/- 1.16 cm, the distance of common iliac bifurcation from the superior border was 1.11 +/ 1.25 cm, the mean (SD) distance of right external iliac from the lateral border of AP field was 2.06 +/- 0.48 cm and for left external iliac artery was 1.90 +/- 0.56 cm. The distance of the external iliac artery from the anterior border of the lateral field was 2.30 +/- 0.74 cm. The distance of the external iliac artery from pelvic rim was 0.59 +/- 0.59 cm, distance of bifurcation of iliac from sacroiliac joint was 0.82 +/- 1.01 cm, the size of the pelvic rim was 12.30 +/- 0.64 cm, sacral width was 8.29 +/- 1.01 cm, anterior promontory symphysis distance was 12.02 +/- 0.92 cm and posterior promontory symphysis distance was 10.98 +/- 0.73 cm. CONCLUSIONS: We observed that conventional radiotherapy using CT simulation based on bone and vessels landmarks provided adequate coverage of pelvic lymph nodes in our patients with prostate cancer. PMID- 27703651 TI - Cancer Screening, Effective or Harmful? PMID- 27703650 TI - Genetic Variations in Leptin and Leptin Receptor and Susceptibility to Colorectal Cancer and Obesity. AB - BACKGROUND: Colorectal cancer (CRC) is the second most commonly diagnosed cancer and the fourth leading cause of cancer-related mortality around the world. OBJECTIVES: With regard to the role of obesity in colorectal cancer (CRC) and the role of leptin in obesity, we investigated whether leptin (LEP) and leptin receptor (LEPR) gene variants are associated with CRC risk. PATIENTS AND METHODS: We evaluated LEP (rs7799039) and LEPR (rs1137101) gene variants by using PCR-RFLP method in 261 cases with CRC and 339 controls. RESULTS: No significant difference was found for rs7799039 and rs1137101gene variants between the cases with CRC and controls. However, the LEPR rs1137101 "GG" genotype compared with "AA" genotype and "AA + AG" genotype was associated with increased risks for obesity, and the differences remained significant after adjustment for confounding factors including age, sex, smoking status, and NSAID use (P = 0.015; OR = 2.42, 95%CI = 1.19 - 4.93 and P = 0.016; OR = 2.28, 95%CI = 1.17 - 4.48, respectively). In addition, the LEPR "G" allele compared with the "A" allele was associated with an increased risk for obesity (P = 0.024; OR = 1.44, 95%CI = 1.05 - 1.98). CONCLUSIONS: Consistent with most previous studies, our findings found no association between LEP (rs7799039) and LEPR (rs1137101) gene variants and CRC risk. However, the LEPR rs1137101 "GG" genotype compared with the "AA" genotype and "AA+AG" genotype was associated with a 2.42-fold and a 2.28-fold increased risk for obesity, respectively.

PMID- 27703653 TI - An Intracranial Gliosis Mimicking Neoplasm: A Dilemma. AB - Intracranial gliosis has no typical clinical signals or imaging characteristics. Therefore, it can be easily misdiagnosed as neoplasm. Hereby, we report a unique case of gliosis that grew outward from the surface of the brain. MRI depicted its signal and enhancement pattern similar to the cerebral gray matter. The diagnosis was confirmed by pathology and immunohistochemistry. Although it was difficult to reach a diagnosis, correlating its origin, growing pattern and MR features and knowing that gliosis can present this way may help in differentiating it from other diseases. PMID- 27703654 TI - Diagnostic Accuracy of Dynamic Contrast Enhanced Magnetic Resonance Imaging in Characterizing Lung Masses. AB - BACKGROUND: Imaging plays a critical role not only in the detection, but also in the characterization of lung masses as benign or malignant. OBJECTIVES: To determine the diagnostic accuracy of dynamic magnetic resonance imaging (MRI) in the differential diagnosis of benign and malignant lung masses. PATIENTS AND METHODS: Ninety-four masses were included in this prospective study. Five dynamic series of T1-weighted spoiled gradient echo (FFE) images were obtained, followed by a T1-weighted FFE sequence in the late phase (5th minutes). Contrast enhancement patterns in the early (25th second) and late (5th minute) phase images were evaluated. For the quantitative evaluation, signal intensity (SI) time curves were obtained and the maximum relative enhancement, wash-in rate, and time-to-peak enhancement of masses in both groups were calculated. RESULTS: The early phase contrast enhancement patterns were homogeneous in 78.2% of the benign masses, while heterogeneous in 74.4% of the malignant tumors. On the late phase images, 70.8% of the benign masses showed homogeneous enhancement, while most of the malignant masses showed heterogeneous enhancement (82.4%). During the first pass, the maximum relative enhancement and wash-in rate values of malignant masses were significantly higher than those of the benign masses (P = 0.03 and 0.04, respectively). The cutoff value at 15% yielded a sensitivity of 85.4%, specificity of 61.2%, and positive predictive value of 68.7% for the maximum relative enhancement. CONCLUSION: Contrast enhancement patterns and SI-time curve analysis of MRI are helpful in the differential diagnosis of benign and malignant lung masses. PMID- 27703655 TI - Brain Tissue Classification Based on Diffusion Tensor Imaging: A Comparative Study Between Some Clustering Algorithms and Their Effect on Different Diffusion Tensor Imaging Scalar Indices. AB - BACKGROUND: Brain segmentation from diffusion tensor imaging (DTI) into white matter (WM), gray matter (GM), and cerebrospinal fluid (CSF) with acceptable results is subjected to many factors. OBJECTIVES: The most important issue in brain segmentation from DTI images is the selection of suitable scalar indices that best describe the required tissue in the images. Specifying suitable clustering method and suitable number of clusters of the selected method are other factors which affects the segmentation process significantly. MATERIALS AND METHODS: The segmentation process is evaluated using four different clustering methods with different number of clusters where some DTI scalar indices for 10 human brains are processed. RESULTS: The aim was to produce results with less segmentation error and a lower computational cost while attempting to minimizing boundary overlapping and minimizing the effect of artifacts due to macroscale scanning. CONCLUSION: The volume ratios of the best produced outputs with respect to the total brain size are 16.7% +/- 3.53% for CSF, 35.05% +/- 1.13% for WM, and 48.2% +/- 2.88% for GM. PMID- 27703656 TI - Diagnostic Value of Dual-Source Computerized Tomography Combined with Perfusion Imaging for Peripheral Pulmonary Embolism. AB - BACKGROUND: Pulmonary embolism has become the third most common cardiovascular disease, which can seriously harm human health. OBJECTIVES: To investigate the diagnostic value of dual-source computerized tomography (CT) and perfusion imaging for peripheral pulmonary embolism. PATIENTS AND METHODS: Thirty-two patients with suspected pulmonary embolism underwent dual-source CT exams. To compare the ability of pulmonary embolism detection software (PED) with CT pulmonary angiography (CTPA) in determining the presence, numbers, and locations of pulmonary emboli, the subsequent images were reviewed by two radiologists using both imaging modalities. Also, the diagnostic consistency between PED and CTPA images and dual-energy pulmonary perfusion imaging (DEPI) for segmental pulmonary embolism was compared. RESULTS: CTPA images revealed 50 (7.81%) segmental and 56 (4.38%) sub-segmental pulmonary embolisms, while the PED images showed 68 (10.63%) segmental and 94 (7.34%) sub-segmental pulmonary embolisms. Thus, the detection rate on PED images for peripheral pulmonary embolism was significantly higher than that of the CTPA images (P < 0.05). There was good consistency for diagnosing segmental pulmonary embolism between PED and CTPA and DEPI (kappa = 0.85). The sensitivity and specificity of DEPI images for the diagnosis of pulmonary embolism were 91.7% and 97.5%, respectively. CONCLUSION: PED software of dual-source CT combined with perfusion imaging can significantly improve the detection rate of peripheral pulmonary embolism. PMID- 27703658 TI - Diagnostic Performance on Low Dose Computed Tomography For Acute Appendicitis Among Attending and Resident Radiologists. AB - BACKGROUND: Low-dose computed tomography (LDCT) techniques can reduce exposure to radiation. Several previous studies have shown that radiation dose reduction in LDCT does not decrease the diagnostic performance for appendicitis among attending radiologists. But, the LDCT diagnostic performance for acute appendicitis in radiology residents with variable training levels has not been well discussed. OBJECTIVES: To compare inter-observer and intra-observer differences of diagnostic performance on non-enhanced LDCT (NE-LDCT) and contrast enhanced standard dose CT (CE-SDCT) for acute appendicitis among attending and resident radiologists. PATIENTS AND METHODS: This retrospective study included 101 patients with suspected acute appendicitis who underwent NE-LDCT and CE-SDCT. The CT examinations were interpreted and recorded on a five-point scale independently by three attending radiologists and three residents with 4, 1 and 1 years of training. Diagnostic performance for acute appendicitis of all readers on both examinations was represented by area under receiver operating characteristic (ROC) curves. Inter-observer and intra-observer AUC values were compared using Jackknife FROC software on both modalities. The diagnostic accuracy of each reader on NE-LDCT was compared with body mass index (BMI) subgroups and noise using independent T test. RESULTS: Diagnostic performances for acute appendicitis were not statistically different for attending radiologists at both examinations. Better performance was noted on the CE-SDCT with a borderline significant difference (P = 0.05) for senior radiology resident. No statistical difference of AUC values was observed between attending radiologists and fourth year resident on both examinations. Statistically significant differences of AUC values were observed between attending radiologists and first year residents (P = 0.001 ~ 0.018) on NE-LDCT. Diagnostic accuracies of acute appendicitis on NE-LDCT for each reader were not significantly related to BMI or noise. CONCLUSION: Attending radiologists could diagnose acute appendicitis accurately on NE-LDCT. Performance of senior residents on NE-LDCT is better than junior residents and comparable to attending radiologists. PMID- 27703659 TI - Imaging Features of Breast Dermatofibrosarcoma Protuberans in Various Modalities Including FDG-PET CT. AB - Dermatofibrosarcoma protuberans is an uncommon malignant mesenchymal tumor of the dermis, which most commonly appears on the body and extremities. A preoperative diagnosis of dermatofibrosarcoma protuberans is extremely difficult, because it is a very rare entity and its appearance is often similar to that of benign breast lesion. Here, we presented a case of breast dermatofibrosarcoma protuberans with associated radiological mammography, ultrasound, magnetic resonance imaging and fludeoxyglucose-positron emission tomography computerized tomography (FDG-PET CT) features. To our knowledge, our case is the first report of PET-CT findings of breast dermatofibrosarcoma protuberans. Furthermore, we reviewed characteristic radiologic features of this rare entity, which are helpful for differentiating it from other primary benign breast lesions. PMID- 27703657 TI - Lower Extremity Arterial Calcification as a Predictor of Coronary Atherosclerosis in Patients with Peripheral Arterial Disease. AB - BACKGROUND: Until now, there has been no study on the relationship between the calcification of the lower extremity arteries and significant coronary arterial disease (CAD). OBJECTIVES: To evaluate whether lower extremity calcium scores (LECS) are associated with CAD and whether this can predict multivessel-CAD in patients with peripheral arterial disease (PAD). PATIENTS AND METHODS: We retrospectively enrolled 103 PAD patients without cardiac symptoms or known CAD. All patients underwent cardiac computed tomography (CT) and lower extremity CT within 1 month and were categorized as nonsignificant CAD, single-CAD, or multivessel-CAD. The coronary calcium scores (CCS) were quantitatively measured according to the Agatston method and LECS were semi-quantitatively measured according to the presence of lower extremity calcification in the segment. The extent of CAD was evaluated according to the presence of >= 50% luminal diameter stenosis in the segment of CAD. RESULTS: LECS in multivessel-CAD were significantly higher than those in nonsignificant CAD (10.0 +/- 5.8 versus 4.0 +/ 3.1, P < 0.001). LECS significantly correlated with CCS (r = 0.831, P < 0.001) and the extent of CAD (r = 0.631, P < 0.001). Multivariate regression analysis demonstrated LECS and log-transformed CCS were independent predictors for multivessel-CAD. In receiver operating characteristic curve analysis, the diagnostic performance of LECS was 0.807 (95% confidence interval = 0.724-0.891, P < 0.001) for predicting multivessel-CAD. CONCLUSION: Peripheral arterial calcification is significantly correlated with CAD extent in patients with PAD. Peripheral arterial calcification can be a useful marker for predicting multivessel-CAD. PMID- 27703660 TI - Dual-Source Computed Tomography Evaluation of Children with Congenital Pulmonary Valve Stenosis. AB - BACKGROUND: Despite dual-source computed tomography (DSCT) technology has been performed well on adults or infants with heart disease, specific knowledge about children with congenital pulmonary valve stenosis (PS) remained to be established. OBJECTIVES: This original research aimed to establish a professional approach of DSCT performing technology on children and to assess the image quality performed by DSCT to establish a diagnostic evaluation for children with PS. PATIENTS AND METHODS: Ninety-eight children with congenital PS referred to affiliated hospital of Jining medical college were recruited from October 2013 to March 2015. Participants were divided into four groups according to different ages (0 - 1, 1 - 3, 3 - 7, 7 - 14), or three groups according to different heart rates (< 90, 90 - 110, > 110). Image quality of pulmonary valves was assessed based on a four-point grading scale (1 - 4 points). Those cases achieving a score of >= 3 points were selected for further investigation, which played a critical role in our analysis. Correlation analysis was used to identify the effects of age and heart rate on image quality. Additionally, the results evaluated by DSCT were compared with those evaluated from the operation, further confirming the accuracy of DSCT. RESULTS: Seventy-two cases (73.4%) achieved a score of >= 3 points based on pulmonary valve imaging, which were available for further diagnosis. There was a statistically significant difference (P < 0.05) between the four groups except 0 - 1 group and 1 - 3 group, 3 - 7 group and 7 - 14 group, and the image quality of elder group was higher than younger group. Image score was gradually decreased with increased heart rate (F = 19.05, P < 0.01). Heart rate was negatively correlated with pulmonary valve scores (r = -0.391, P < 0.001), while there was no correlation between age and scores (r = 0.185, P = 0.070). The number, shape, commissure, and opening status of pulmonary valves evaluated by DSCT were the same as the results of operation. CONCLUSION: Heart rate serves a pivotal role in imaging quality of DSCT. DSCT provides a functional evaluation of children with congenital PS and consequently contributes to a theoretical basis for corresponding treatment protocols. PMID- 27703661 TI - Quantitative Evaluation of the Fetal Cerebellar Vermis Using the Median View on Two-Dimensional Ultrasound. AB - BACKGROUND: Evaluation of the cerebellum and vermis is one of the integral parts of the fetal cranial anomaly screening. OBJECTIVES: The aim of this study was to create a nomogram for fetal vermis measurements between 17 and 30 gestational weeks. PATIENTS AND METHODS: This prospective study was conducted on 171 volunteer pregnant women between March 2013 and December 2014. Measurements of the fetal cerebellar vermis diameters in the sagittal plane were performed by two dimensional transabdominal ultrasonography. RESULTS: Optimal median planes were obtained in 117 of the cases. Vermian diameters as a function of gestational age were expressed by regression equations and the correlation coefficients were found to be highly statistically significant (P < 0.001). The normal mean (+/- standard deviation) for each gestational week was also defined. CONCLUSION: This study presents the normal range of the two-dimensional fetal vermian measurements between 17 and 30 gestational weeks. In the absence of a three-dimensional ultrasonography, two-dimensional ultrasonography could also be used confidently with more time and effort. PMID- 27703662 TI - In Vivo Evaluation of the Biomechanical Properties of Optic Nerve and Peripapillary Structures by Ultrasonic Shear Wave Elastography in Glaucoma. AB - BACKGROUND: Primary open-angle glaucoma is a multifactorial serious disease characterized by progressive retinal ganglion cell death and loss of visual field. OBJECTIVES: The purposes of this study were to investigate shear wave elastography (SWE) use in the evaluation of the optic nerve (ON) and peripapillary structures, and to compare the findings between glaucomatous and control eyes. PATIENTS AND METHODS: A case-controlled study, including 21 patients with primary open-angle glaucoma and 21 age-matched control subjects, was carried out. All of the participants had comprehensive ophthalmological exams that included corneal biomechanical measurements with ocular response analyzer. In vivo evaluation of the biomechanical properties of the ON and peripapillary structures were performed with SWE in all participants. The Kolmogorov-Smirnov test was used to analyze the normal distribution of data. Differences of parameters in ophthalmologic data and stiffness values of patients with and without glaucoma were evaluated using the Mann-Whitney U test. RESULTS: There were no statistically significant differences between the glaucoma and control groups in terms of age (P > 0.05) and gender (P > 0.05). Corneal hysteresis was lower in the glaucoma group (P < 0.05). Corneal compensated intraocular pressure and Goldmann correlated intraocular pressure were higher in the glaucoma group (P < 0.0001 for both). The mean stiffness of the ON and peripapillary structures were significantly higher in glaucoma patients for each measured region (P < 0.05). CONCLUSION: The study evaluated the biomechanical properties of the ON and peripapillary structures in vivo with SWE in glaucoma. We observed stiffer ON and peripapillary tissue in glaucomatous eyes, indicating that SWE claims new perspectives in the evaluation of ON and peripapillary structures in glaucoma disease.

PMID- 27703663 TI - How leukocytes trigger opening and sealing of gaps in the endothelial barrier. AB - The entry of leukocytes into tissues requires well-coordinated interactions between the immune cells and endothelial cells which form the inner lining of blood vessels. The molecular basis for recognition, capture, and adhesion of leukocytes to the endothelial apical surface is well studied. This review will focus on recent advances in our understanding of events following the firm interaction of leukocytes with the inner surface of the blood vessel wall. We will discuss how leukocytes initiate the transmigration (diapedesis) process, trigger the opening of gaps in the endothelial barrier, and eventually move through this boundary.

It is increasingly popular due to its digital nature, which provides more accurate quantification and higher sensitivity than traditional real-time PCR. However, clinical adoption has been slowed in part by the lack of software tools available for analyzing ddPCR data. Here, we present ddpcr - a new R package for ddPCR visualization and analysis. In addition, ddpcr includes a web application (powered by the Shiny R package) that allows users to analyze ddPCR data using an interactive graphical interface. PMID- 27703664 TI - Recent advances in T-cell engineering for use in immunotherapy. AB - Adoptive T-cell therapies have shown exceptional promise in the treatment of cancer, especially B-cell malignancies. Two distinct strategies have been used to redirect the activity of ex vivo engineered T cells. In one case, the well-known ability of the T-cell receptor (TCR) to recognize a specific peptide bound to a major histocompatibility complex molecule has been exploited by introducing a TCR against a cancer-associated peptide/human leukocyte antigen complex. In the other strategy, synthetic constructs called chimeric antigen receptors (CARs) that contain antibody variable domains (single-chain fragments variable) and signaling domains have been introduced into T cells. Whereas many reviews have described these two approaches, this review focuses on a few recent advances of significant interest. The early success of CARs has been followed by questions about optimal configurations of these synthetic constructs, especially for efficacy against solid tumors. Among the many features that are important, the dimensions and stoichiometries of CAR/antigen complexes at the synapse have recently begun to be appreciated. In TCR-mediated approaches, recent evidence that mutated peptides (neoantigens) serve as targets for endogenous T-cell responses suggests that these neoantigens may also provide new opportunities for adoptive T-cell therapies with TCRs. PMID- 27703667 TI - Rapid and high throughput molecular identification of diverse mosquito species by high resolution melting analysis. AB - Mosquitoes are a diverse group of invertebrates, with members that are among the most important vectors of diseases. The correct identification of mosquitoes is paramount to the control of the diseases that they transmit. However, morphological techniques depend on the quality of the specimen and often unavailable taxonomic expertise, which may still not be able to distinguish mosquitoes among species complexes (sibling and cryptic species). High resolution melting (HRM) analyses, a closed-tube, post-polymerase chain reaction (PCR) method used to identify variations in nucleic acid sequences, has been used to differentiate species within the Anopheles gambiae and Culex pipiens complexes. We validated the use of PCR-HRM analyses to differentiate species within Anopheles and within each of six genera of culicine mosquitoes, comparing primers targeting cytochrome b ( cyt b), NADH dehydrogenase subunit 1 (ND1), intergenic spacer region (IGS) and cytochrome c oxidase subunit 1 ( COI) gene regions. HRM analyses of amplicons from all the six primer pairs successfully differentiated two or more mosquito species within one or more genera ( Aedes ( Ae. vittatus from Ae. metallicus), Culex ( Cx. tenagius from Cx. antennatus, Cx. neavei from Cx. duttoni, cryptic Cx. pipiens species), Anopheles ( An. gambiae s.s. from An. arabiensis) and Mansonia ( Ma. africana from Ma. uniformis)) based on their HRM profiles. However, PCR-HRM could not distinguish between species within Aedeomyia ( Ad. africana and Ad. furfurea), Mimomyia ( Mi. hispida and Mi. splendens) and Coquillettidia ( Cq. aurites, Cq. chrysosoma, Cq. fuscopennata, Cq. metallica, Cq. microannulatus, Cq. pseudoconopas and Cq. versicolor) genera using any of the primers. The IGS and COI barcode region primers gave the best and most definitive separation of mosquito species among anopheline and culicine mosquito genera, respectively, while the other markers may serve to confirm identifications of closely related sub-species. This approach can be employed for rapid identification of mosquitoes. PMID- 27703668 TI - Protein domain architectures provide a fast, efficient and scalable alternative to sequence-based methods for comparative functional genomics. AB - A functional comparative genome analysis is essential to understand the mechanisms underlying bacterial evolution and adaptation. Detection of functional orthologs using standard global sequence similarity methods faces several problems; the need for defining arbitrary acceptance thresholds for similarity and alignment length, lateral gene acquisition and the high computational cost for finding bi-directional best matches at a large scale. We investigated the use of protein domain architectures for large scale functional comparative analysis as an alternative method. The performance of both approaches was assessed through functional comparison of 446 bacterial genomes sampled at different taxonomic levels. We show that protein domain architectures provide a fast and efficient alternative to methods based on sequence similarity to identify groups of functionally equivalent proteins within and across taxonomic bounderies. As the computational cost scales linearly, and not quadratically with the number of genomes, it is suitable for large scale comparative analysis. Running both methods in parallel pinpoints potential functional adaptations that may add to bacterial fitness. PMID- 27703669 TI - Factors affecting stone free rate of primary percutaneous nephrolithotomy on staghorn calculi: a single center experience of 15 years. AB - Objectives: Percutaneous nephrolithotomy on staghorn calculi is challenging for urologists because it is difficult to remove all of the stones. The purpose of this study was to evaluate the associated factors of stone-free rate after primary percutaneous nephrolithotomy on staghorn calculi in a large series of patients at a single, tertiary referral, endourologic stone center. Methods: We collected data from medical record between January 2000 and December 2015. A total of 345 primary percutaneous nephrolithotomy procedures were performed for patients with staghorn calculi. This study included both and made no distinction between partial and complete staghorn calculi. Stone-free is defined as the absence of residual stones after undergoing percutaneous nephrolithotomy for the first time. Significant factors from univariate analysis that correlated with stone-free rate after primary percutaneous nephrolithotomy of staghorn stone were further analyzed using multivariate regression analysis. Results: The mean patient age was 52.23+/-10.38 years. The stone-free rate of percutaneous nephrolithotomy monotherapy was 62.6%. The mean operating time was 79.55+/-34.46 minutes. The mean length of stay in hospital was 4.29+/-3.00 days. Using the chi square test, history of ipsilateral open renal stone surgery ( p = 0.01), stone burden ( p = < 0.001), and type of anesthesia ( p = 0.04) had a significant impact on the stone-free. From multivariate analysis, the history of ipsilateral open renal stone surgery [OR 0.48; 95% CI 0.28-0.81; p 0.01] and the stone burden [OR 0.28; 95% CI 0.18-0.45; p 0.00] were significant independent risk factors for stone-free. PMID- 27703670 TI - Opportunities and considerations for visualising neuroimaging data on very large displays. AB - Neuroimaging experiments can generate impressive volumes of data and many images of the results. This is particularly true of multi-modal imaging studies that use more than one imaging technique, or when imaging is combined with other assessments. A challenge for these studies is appropriate visualisation of results in order to drive insights and guide accurate interpretations. Next generation visualisation technology therefore has much to offer the neuroimaging community. One example is the Imperial College London Data Observatory; a high resolution (132 megapixel) arrangement of 64 monitors, arranged in a 313 degree arc, with a 6 metre diameter, powered by 32 rendering nodes. This system has the potential for high-resolution, large-scale display of disparate data types in a space designed to promote collaborative discussion by multiple researchers and/or clinicians. Opportunities for the use of the Data Observatory are discussed, with particular reference to applications in Multiple Sclerosis (MS) research and clinical practice. Technical issues and current work designed to optimise the use of the Data Observatory for neuroimaging are also discussed, as well as possible future research that could be enabled by the use of the system in combination with eye-tracking technology. PMID- 27703671 TI - Epidemiology, virulence factors and management of the pneumococcus. AB - Pneumococcal infections continue to cause significant morbidity and mortality in patients throughout the world. This microorganism remains the most common bacterial cause of community-acquired pneumonia and is associated with a considerable burden of disease and health-care costs in both developed and developing countries. Emerging antibiotic resistance has been a concern because of its potential negative impact on the outcome of patients who receive standard antibiotic therapy. However, there have been substantial changes in the epidemiology of this pathogen in recent years, not least of which has been due to the use of pneumococcal conjugate vaccines in children, with subsequent herd protection in unvaccinated adults and children. Furthermore, much recent research has led to a better understanding of the virulence factors of this pathogen and their role in the pathogenesis of severe pneumococcal disease, including the cardiac complications, as well as the potential role of adjunctive therapy in the management of severely ill cases. This review will describe recent advances in our understanding of the epidemiology, virulence factors, and management of pneumococcal community-acquired pneumonia. PMID- 27703672 TI - Ending the HIV/AIDS epidemic in low- and middle-income countries by 2030: is it possible? AB - The international community has committed to ending the epidemics of HIV/AIDS, tuberculosis, malaria, and neglected tropical infections by 2030, and this bold stance deserves universal support. In this paper, we discuss whether this ambitious goal is achievable for HIV/AIDS and what is needed to further accelerate progress. The joint United Nations Program on HIV/AIDS (UNAIDS) 90-90 90 targets and the related strategy are built upon currently available health technologies that can diagnose HIV infection and suppress viral replication in all people with HIV. Nonetheless, there is much work to be done in ensuring equitable access to these HIV services for key populations and those who remain outside the rims of the traditional health services. Identifying a cure and a preventive vaccine would further help accelerate progress in ending the epidemic. Other disease control programmes could learn from the response to the HIV/AIDS epidemic. PMID- 27703674 TI - Correlation between secondary thrombosis in epileptic patients and serum levels of folate and vitamin B12. AB - Epilepsy is a chronic brain dysfunction syndrome and nervous system disease whose pathogenesis remains to be determined. The aim of the present study was to analyze the correlation between secondary thrombosis and the serum levels of folate and vitamin B12 in epileptic patients, as well as to determine whether the supplementation of folate and vitamin B12 was associated with a decreased incidence of thrombosis, and provide the basis for novel clinical treatment. A total of 37 patients, diagnosed as epileptic with secondary thrombosis between April 2012 and April 2014, were included in the treatment group. A total of 37 epileptic patients without secondary thrombosis were included in the control group. The serum levels of homocysteine, folate and vitamin B12 in the two groups and in the epileptic patients with intracranial thrombosis or peripheral thrombosis were compared. According to the Guidance of Epilepsy, the patients in the two groups were administered antiepileptic drugs (AEDs) with the supplementation of folate tablet (0.4 mg/day) and vitamin B12 tablet (100 ug/day). These indicators and the incidence of thrombosis in the two groups were compared after 1 year. The serum levels of homocysteine in the two groups were higher than normal, and the levels in the treatment group were significantly higher than those in the control group. The serum levels of folate and vitamin B12 in the treatment group were significantly higher than those in the control group and the difference was statistically significant (P<0.05). The Pearson correlation analysis revealed that the serum levels of folate and vitamin B12 were not associated with the serum level of homocysteine (P>0.05). The logistic regression analysis revealed that the serum levels of folate and vitamin B12 were independent risk factors for epilepsy with secondary thrombosis [folate: odds ratio (OR)=0.635, P=0.038; vitamin B12: OR=0.418, P=0.042]. The differences in the serum levels of homocysteine, folate and vitamin B12 in the epileptic patients with intracranial thrombosis or peripheral thrombosis were not statistically significant (P>0.05). The serum levels of homocysteine in the two groups, were significantly decreased, while the levels of folate and vitamin B12 were significantly increased. The differences in the serum levels of homocysteine, folate and vitamin B12 in the two groups were not statistically significant (P>0.05). The differences in the incidence of thrombosis in the two groups were not statistically significant (P>0.05). In conclusion, the serum levels of folate and vitamin B12 were independent of serum homocysteine, and were the dependent risk factors for primary epilepsy with secondary thrombosis. The supplementation of folate and vitamin B12 may be beneficial for the prevention of epilepsy with secondary thrombosis, making it valuable in application. PMID- 27703675 TI - Bowel movement frequency, oxidative stress and disease prevention. AB - The significance of diet for disease prevention has long been recognised. Dietary recommendations have therefore been integrated in health promotion messages. Gastrointestinal functioning is essential for the digestion of nutrients. Oxidative stress has been observed in patients with constipation, as well as in those with colorectal cancer, cardiovascular disease and other chronic illnesses associated with constipation. The coexistence of colorectal neoplasia and coronary artery disease has been incriminated for exposure to common risk factors associated with increased oxidative stress. It was recently demonstrated that bowel movement frequency is inversely associated with cardiovascular mortality. The aim of the present study was to review the relevant literature in light of these findings. It was concluded that suboptimal functioning of the large bowel may contribute to oxidative stress and, therefore, to increased mortality. Bowel movement frequency may represent a simple quantifiable indicator of adequate colonic function and it is dependent on diet, exercise and other lifestyle factors, but also on individual characteristics, including colonic microbiota. Future health promotion actions may improve the prevention of a number of diseases by advocating lifestyle personalisation for assuring optimal intestinal functioning. PMID- 27703673 TI - Plasticity of the Leishmania genome leading to gene copy number variations and drug resistance. AB - Leishmania has a plastic genome, and drug pressure can select for gene copy number variation (CNV). CNVs can apply either to whole chromosomes, leading to aneuploidy, or to specific genomic regions. For the latter, the amplification of chromosomal regions occurs at the level of homologous direct or inverted repeated sequences leading to extrachromosomal circular or linear amplified DNAs. This ability of Leishmania to respond to drug pressure by CNVs has led to the development of genomic screens such as Cos-Seq, which has the potential of expediting the discovery of drug targets for novel promising drug candidates. PMID- 27703676 TI - Associations and prognostic significance of p27Kip1, Jab1 and Skp2 in non-Hodgkin lymphoma. AB - Non-Hodgkin lymphoma (NHL) is a primary tumor arising in lymph nodes and lymphoid tissue. The incidence of NHL is increasing at an annual rate of 3%. The human Jun activation domain-binding protein 1/COP9 signalosome subunit 5 (Jab1/CSN5) is a negative regulator of the cell cycle inhibitor p27Kip1 and abnormal expression of Jab1 is correlated with reduced p27 expression and associated with advanced tumor stage and poor prognosis in several human cancers. F-box protein S-phase kinase interacting protein-2 (Skp2), the substrate recognition subunit of the Skp1-Cul1 F-box protein ubiquitin protein ligase complex, is required for the ubiquitination and consequent degradation of p27. The Skp2 protein is overexpressed in several human cancers and is associated with the degree of differentiation and the prognosis. The aim of the present study was to investigate the expression status of p27Kip1, Jab1 and Skp2 by immunohistochemistry, and assess their prognostic significance in patients with NHL. Immunohistochemical analysis revealed an inverse association between Jab1 and p27 in NHL tissue samples. Kaplan-Meier analysis demonstrated that Jab1 overexpression, Skp2 overexpression and low p27 expression were significantly associated with poor prognosis. Among clinicopathological parameters, overexpression of Jab1 was significantly associated with tumor size and International Prognostic Index (IPI), whereas Skp2 expression was significantly associated with metastasis and IPI. These findings suggest that the overexpression of Jab1 or Skp2 plays an important role in the pathogenesis of NHL. Thus, the expression of p27Kip1, Jab1 and Skp2 provided a clinical reference for the treatment of NHL. PMID- 27703677 TI - Significant antitumor response of disseminated glioblastoma to bevacizumab resulting in long-term clinical remission in a patient with encephalocraniocutaneous lipomatosis: A case report. AB - The prognosis of recurrent and disseminated glioblastoma is very poor. Bevacizumab is an effective established therapy for recurrent glioblastoma following treatment with radiotherapy plus temozolomide. However, the efficacy of bevacizumab is limited to prolonging progression-free survival, without significant prolongation of the overall survival. We herein report a case of glioblastoma in a 32-year-old female patient with encephalocraniocutaneous lipomatosis (ECCL) that had disseminated following surgical resection and subsequent treatment with temozolomide and radiation therapy. The disseminated tumors disappeared completely after five courses of bevacizumab therapy. Surprisingly, the patient has remained in clinical remission for >2.5 years after dissemination by continuing this therapy. To the best of our knowledge, this is the first case of long-time clinical remission following glioblastoma dissemination and treatment with bevacizumab. In the present case, bevacizumab exerted an atypically strong antitumor effect against disseminated glioblastoma after multidisciplinary treatments had already been applied. Moreover, this is the first report of ECCL associated with a malignant brain tumor. PMID- 27703678 TI - Mucinous adenocarcinoma of the bladder: A case report and review of the literature. AB - Mucinous adenocarcinoma of the bladder is rare. The most common symptoms are hematuria, suprapubic pain and dysuria. The patient in the present case was a 59 year-old female who presented with a tumor sized ~5.0*3.4 cm, located in the anterior bladder wall, which was pathologically diagnosed as mucinous bladder adenocarcinoma. The stage at presentation was considered to be advanced and inoperable, due to extensive local invasion. For this type of cancer, early diagnosis is crucial. If the cancer is limited to the bladder, the survival rate may exceed 75%. Thus, for patients with confirmed or highly suspicious bladder mucinous adenocarcinoma, radical bladder cancer resection is required. The 5-year survival rate of this type of cancer is 35-55%. In the present case, the cancer of the patient was considered inoperable and 3 months later she succumbed to the disease. PMID- 27703680 TI - Prevalence and distribution pattern of nodal metastases in advanced ovarian cancer. AB - The objective of this study was to examine the relevance of pelvic and para aortic lymph node involvement and the tumour characteristics affecting nodal metastases and survival in primary advanced ovarian cancer. A total of 130 consecutive patients were retrospectively investigated. All the patients received stage-related surgery with pelvic and para-aortic lymphadenectomy. The median follow-up was 53.5 months. The clinicopathological parameters and distribution pattern of nodal metastases were evaluated. Lymph node metastases were detectable in 74.62% of the cases. Overall, both pelvic and para-aortic nodes were affected in 35.9% of the patients, whereas 13.3% had metastases only in the pelvic and 13.3% only in the para-aortic lymph nodes. Histological grade 1/2 and 3, serous and endometrioid histology were independent predictors of nodal metastasis. Serous and endometrioid cancers have shown a predilection for metastasis to the pelvic lymph nodes alone, both to the pelvic and the para-aortic nodes, or the para-aortic nodes alone. Overall survival was significantly positively affected by serous histology with positive nodes (P=0.043). It is crucial to investigate the risk factors and metastatic patterns of such patients in a multicenter analysis to evaluate individual subgroups. Prospective studies are required to investigate the prognostic effect of lymphadenectomy in advanced ovarian cancer and its association with histology and distribution pattern of nodal metastasis. PMID- 27703681 TI - Nuclear conversion theory: molecular hydrogen in non-magnetic insulators. AB - The hydrogen conversion patterns on non-magnetic solids sensitively depend upon the degree of singlet/triplet mixing in the intermediates of the catalytic reaction. Three main 'symmetry-breaking' interactions are brought together. In a typical channel, the electron spin-orbit (SO) couplings introduce some magnetic excitations in the non-magnetic solid ground state. The electron spin is exchanged with a molecular one by the electric molecule-solid electron repulsion, mixing the bonding and antibonding states and affecting the molecule rotation. Finally, the magnetic hyperfine contact transfers the electron spin angular momentum to the nuclei. Two families of channels are considered and a simple criterion based on the SO coupling strength is proposed to select the most efficient one. The denoted 'electronic' conversion path involves an emission of excitons that propagate and disintegrate in the bulk. In the other denoted 'nuclear', the excited electron states are transients of a loop, and the electron system returns to its fundamental ground state. The described model enlarges previous studies by extending the electron basis to charge-transfer states and 'continui' of band states, and focuses on the broadening of the antibonding molecular excited state by the solid conduction band that provides efficient tunnelling paths for the hydrogen conversion. After working out the general conversion algebra, the conversion rates of hydrogen on insulating and semiconductor solids are related to a few molecule-solid parameters (gap width, ionization and affinity potentials) and compared with experimental measures. PMID- 27703679 TI - Prognostic impact of primary tumor SUVmax on preoperative 18F-fluoro-2-deoxy-D glucose positron emission tomography and computed tomography in endometrial cancer and uterine carcinosarcoma. AB - The objective of the present study was to investigate the usefulness of the maximum standardized uptake value (SUVmax) of the primary tumor on preoperative 18F-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography and computed tomography (PET/CT) as a prognostic indicator in patients with endometrial neoplasms. A total of 75 patients with endometrial cancer or uterine carcinosarcoma who underwent surgical treatment were included in the present study. All patients underwent preoperative PET/CT, and the correlation between the SUVmax of the primary tumor and clinical outcomes was analyzed. The SUVmax was significantly higher in patients with stage II/III disease, a histology of grade 3 endometrioid adenocarcinoma and carcinosarcoma, a positive lymph node (LN) status, positive lymph-vascular space involvement (LVSI), and deep (>=1/2) myometrial invasion. Receiver operating characteristic curve analysis revealed that the optimal cut-off values of SUVmax for predicting a positive LN, LVSI and deep myometrial invasion were 7.49, 6.45 and 6.45, respectively. The overall survival (OS) and progression-free survival (PFS) of patients with a high SUVmax were significantly lower compared with those of patients with a low SUVmax using the cut-off value of 7.30. However, no significant difference was observed in the OS or PFS between the high and low SUVmax groups when analyzed in carcinosarcoma patients alone. Finally, multivariate analyses demonstrated that the SUVmax of the primary tumor was an independent prognostic factor for impaired PFS in 55 endometrioid adenocarcinoma patients; however, not in all patients, including those with carcinosarcoma. The present findings demonstrated that the SUVmax of the primary tumor may be a useful biomarker for predicting clinical outcomes of patients with endometrial cancer, although its prognostic impact appears to be limited in patients with uterine carcinosarcoma. PMID- 27703682 TI - A modified predator-prey model for the interaction of police and gangs. AB - A modified predator-prey model with transmissible disease in both the predator and prey species is proposed and analysed, with infected prey being more vulnerable to predation and infected predators hunting at a reduced rate. Here, the predators are the police and the prey the gang members. In this system, we examine whether police control of gangs is possible. The system is analysed with the help of stability analyses and numerical simulations. The system has five steady states-four of which involve no core gang members and one in which all the populations coexist. Thresholds are identified which determine when the predator and prey populations survive and when the disease remains endemic. For parameter values where the spread of disease among the police officers is greater than the death of the police officers, the diseased predator population survives, when it would otherwise become extinct. PMID- 27703683 TI - Silver-catalysed azide-alkyne cycloaddition (AgAAC): assessing the mechanism by density functional theory calculations. AB - 'Click reactions' are the copper catalysed dipolar cycloaddition reaction of azides and alkynes to incorporate nitrogens into a cyclic hydrocarbon scaffold forming a triazole ring. Owing to its efficiency and versatility, this reaction and the products, triazole-containing heterocycles, have immense importance in medicinal chemistry. Copper is the only known catalyst to carry out this reaction, the mechanism of which remains unclear. We report here that the 'click reactions' can also be catalysed by silver halides in non-aqueous medium. It constitutes an alternative to the well-known CuAAC click reaction. The yield of the reaction varies on the type of counter ion present in the silver salt. This reaction exhibits significant features, such as high regioselectivity, mild reaction conditions, easy availability of substrates and reasonably good yields. In this communication, the findings of a new catalyst along with the effect of solvent and counter ions will help to decipher the still obscure mechanism of this important reaction. PMID- 27703684 TI - Patterns and biases in climate change research on amphibians and reptiles: a systematic review. AB - Climate change probably has severe impacts on animal populations, but demonstrating a causal link can be difficult because of potential influences by additional factors. Assessing global impacts of climate change effects may also be hampered by narrow taxonomic and geographical research foci. We review studies on the effects of climate change on populations of amphibians and reptiles to assess climate change effects and potential biases associated with the body of work that has been conducted within the last decade. We use data from 104 studies regarding the effect of climate on 313 species, from 464 species-study combinations. Climate change effects were reported in 65% of studies. Climate change was identified as causing population declines or range restrictions in half of the cases. The probability of identifying an effect of climate change varied among regions, taxa and research methods. Climatic effects were equally prevalent in studies exclusively investigating climate factors (more than 50% of studies) and in studies including additional factors, thus bolstering confidence in the results of studies exclusively examining effects of climate change. Our analyses reveal biases with respect to geography, taxonomy and research question, making global conclusions impossible. Additional research should focus on under represented regions, taxa and questions. Conservation and climate policy should consider the documented harm climate change causes reptiles and amphibians. PMID- 27703685 TI - Fossil clam shells reveal unintended carbon cycling consequences of Colorado River management. AB - Water management that alters riverine ecosystem processes has strongly influenced deltas and the people who depend on them, but a full accounting of the trade-offs is still emerging. Using palaeoecological data, we document a surprising biogeochemical consequence of water management in the Colorado River basin. Complete allocation and consumptive use of the river's flow has altered the downstream estuarine ecosystem, including the abundance and composition of the mollusc community, an important component in estuarine carbon cycling. In particular, population declines in the endemic Colorado delta clam, Mulinia coloradoensis, from 50--125 individuals m-2 in the pre-dam era to three individuals m-2 today, have likely resulted in a reduction, on the order of 5900 15 000 t C yr-1 (4.1-10.6 mol C m-2 yr-1), in the net carbon emissions associated with molluscs. Although this reduction is large within the estuarine system, it is small in comparison with annual global carbon emissions. Nonetheless, this finding highlights the need for further research into the effects of dams, diversions and reservoirs on the biogeochemistry of deltas and estuaries worldwide, underscoring a present need for integrated water and carbon planning. PMID- 27703686 TI - Prevalence rates of health and welfare conditions in broiler chickens change with weather in a temperate climate. AB - Climate change impact assessment and adaptation research in agriculture has focused primarily on crop production, with less known about the potential impacts on livestock. We investigated how the prevalence of health and welfare conditions in broiler (meat) chickens changes with weather (temperature, rainfall, air frost) in a temperate climate. Cases of 16 conditions were recorded at approved slaughterhouses in Great Britain. National prevalence rates and distribution mapping were based on data from more than 2.4 billion individuals, collected between January 2011 and December 2013. Analysis of temporal distribution and associations with national weather were based on monthly data from more than 6.8 billion individuals, collected between January 2003 and December 2013. Ascites, bruising/fractures, hepatitis and abnormal colour/fever were most common, at annual average rates of 29.95, 28.00, 23.76 and 22.29 per 10 000, respectively. Ascites and abnormal colour/fever demonstrated clear annual cycles, with higher rates in winter than in summer. Ascites prevalence correlated strongly with maximum temperature at 0 and -1 month lags. Abnormal colour/fever correlated strongly with temperature at 0 lag. Maximum temperatures of approximately 8 degrees C and approximately 19 degrees C marked the turning points of curve in a U-shaped relationship with mortality during transportation and lairage. Future climate change research on broilers should focus on preslaughter mortality. PMID- 27703687 TI - Social learning solves the problem of narrow-peaked search landscapes: experimental evidence in humans. AB - The extensive use of social learning is considered a major reason for the ecological success of humans. Theoretical considerations, models and experiments have explored the evolutionary basis of social learning, showing the conditions under which learning from others is more adaptive than individual learning. Here we present an extension of a previous experimental set-up, in which individuals go on simulated 'hunts' and their success depends on the features of a 'virtual arrowhead' they design. Individuals can modify their arrowhead either by individual trial and error or by copying others. We study how, in a multimodal adaptive landscape, the smoothness of the peaks influences learning. We compare narrow peaks, in which solutions close to optima do not provide useful feedback to individuals, to wide peaks, where smooth landscapes allow an effective hill climbing individual learning strategy. We show that individual learning is more difficult in narrow-peaked landscapes, but that social learners perform almost equally well in both narrow- and wide-peaked search spaces. There was a weak trend for more copying in the narrow than wide condition, although as in previous experiments social information was generally underutilized. Our results highlight the importance of tasks' design space when studying the adaptiveness of high fidelity social learning. PMID- 27703688 TI - Differential phenotypic and genetic expression of defence compounds in a plant herbivore interaction along elevation. AB - Elevation gradients impose large differences in abiotic and biotic conditions over short distances, in turn, likely driving differences in gene expression more than would genetic variation per se, as natural selection and drift are less likely to fix alleles at such a narrow spatial scale. As elevation increases, the pressure exerted on plants by herbivores and on arthropod herbivores by predators decreases, and organisms spanning the elevation gradient are thus expected to show lower levels of defence at high elevation. The alternative hypothesis, based on the optimal defence theory, is that defence allocation should be higher in low resource habitats such as those at high elevation, due to higher costs associated with tissue replacement. In this study, we analyse variation with elevation in (i) defence compound content in the plant Lotus corniculatus and (ii) gene expression associated with defence against predators in the specific phytophagous moth, Zygaena filipendulae. Both species produce cyanogenic glycosides (CNglcs) such as lotaustralin and linamarin as defence mechanisms, with the moth, in addition, being able to sequester CNglcs from its host plant. Specifically, we tested the assumption that the defence-associated phenotype in plants and the gene expression in the insect herbivore should covary between low- and high elevation environments. We found that L. corniculatus accumulated more CNglcs at high elevation, a result in agreement with the optimal defence theory. By contrast, we found that the levels of expression in the defence genes of Z. filipendulae larvae were not related to the CNglc content of their host plant. Overall, expression levels were not correlated with elevation either, with the exception of the UGT33A1 gene, which showed a marginally significant trend towards higher expression at high elevation when using a simple statistical framework. These results suggest that the defence phenotype of plants against herbivores, and subsequent herbivore sequestration machineries and de novo production, are based on a complex network of interactions. PMID- 27703689 TI - Importance of metabolic rate to the relationship between the number of genes in a functional category and body size in Peto's paradox for cancer. AB - Elucidation of tumour suppression mechanisms is a major challenge in cancer biology. Therefore, Peto's paradox, or low cancer incidence in large animals, has attracted focus. According to the gene-abundance hypothesis, which considers the increase/decrease in cancer-related genes with body size, researchers evaluated the associations between gene abundance and body size. However, previous studies only focused on a few specific gene functions and have ignored the alternative hypothesis (metabolic rate hypothesis): in this hypothesis, the cellular metabolic rate and subsequent oxidative stress decreases with increasing body size. In this study, we have elected to explore the gene-abundance hypothesis taking into account the metabolic rate hypothesis. Thus, we comprehensively investigated the correlation between the number of genes in various functional categories and body size while at the same time correcting for the mass-specific metabolic rate (Bc). A number of gene functions that correlated with body size were initially identified, but they were found to be artefactual due to the decrease in Bc with increasing body size. By contrast, immune system-related genes were found to increase with increasing body size when the correlation included this correction for Bc. These findings support the gene-abundance hypothesis and emphasize the importance of also taking into account the metabolic rate when evaluating gene abundance-body size relationships. This finding may be useful for understanding cancer evolution and tumour suppression mechanisms as well as for determining cancer-related genes and functions. PMID- 27703690 TI - Monocular blur alters the tuning characteristics of stereopsis for spatial frequency and size. AB - Our sense of depth perception is mediated by spatial filters at different scales in the visual brain; low spatial frequency channels provide the basis for coarse stereopsis, whereas high spatial frequency channels provide for fine stereopsis. It is well established that monocular blurring of vision results in decreased stereoacuity. However, previous studies have used tests that are broadband in their spatial frequency content. It is not yet entirely clear how the processing of stereopsis in different spatial frequency channels is altered in response to binocular input imbalance. Here, we applied a new stereoacuity test based on narrow-band Gabor stimuli. By manipulating the carrier spatial frequency, we were able to reveal the spatial frequency tuning of stereopsis, spanning from coarse to fine, under blurred conditions. Our findings show that increasing monocular blur elevates stereoacuity thresholds 'selectively' at high spatial frequencies, gradually shifting the optimum frequency to lower spatial frequencies. Surprisingly, stereopsis for low frequency targets was only mildly affected even with an acuity difference of eight lines on a standard letter chart. Furthermore, we examined the effect of monocular blur on the size tuning function of stereopsis. The clinical implications of these findings are discussed.

The molecular and architectural aspects of the cytoskeleton have been playing a prominent role in our understanding of the origin and evolution of eukaryotes. In this study, we seek to investigate the cytoskeleton architecture and its evolutionary significance in understudied amoeboid lineages belonging to Amoebozoa. These amoebae primarily use cytoplasmic extensions supported by the cytoskeleton to perform important cellular processes such as movement and feeding. Amoeboid structure has important taxonomic significance, but, owing to techniques used, its potential significance in understanding diversity of the group has been seriously compromised, leading to an under-appreciation of its value. Here, we used immunocytochemistry and confocal microscopy to study the architecture of microtubules (MTs) and F-actin in diverse groups of amoebae. Our results demonstrate that all Amoebozoa examined are characterized by a complex cytoskeletal array, unlike what has been previously thought to exist. Our results not only conclusively demonstrate that all amoebozoans possess complex cytoplasmic MTs, but also provide, for the first time, a potential synapomorphy for the molecularly defined Amoebozoa clade. Based on this evidence, the last common ancestor of amoebozoans is hypothesized to have had a complex interwoven MT architecture limited within the granular cell body. We also generate several cytoskeleton characters related to MT and F-actin, which are found to be robust for defining groups in deep and shallow nodes of Amoebozoa. PMID- 27703692 TI - Geochemistry, faunal composition and trophic structure in reducing sediments on the southwest South Georgia margin. AB - Despite a number of studies in areas of focused methane seepage, the extent of transitional sediments of more diffuse methane seepage, and their influence upon biological communities is poorly understood. We investigated an area of reducing sediments with elevated levels of methane on the South Georgia margin around 250 m depth and report data from a series of geochemical and biological analyses. Here, the geochemical signatures were consistent with weak methane seepage and the role of sub-surface methane consumption was clearly very important, preventing gas emissions into bottom waters. As a result, the contribution of methane-derived carbon to the microbial and metazoan food webs was very limited, although sulfur isotopic signatures indicated a wider range of dietary contributions than was apparent from carbon isotope ratios. Macrofaunal assemblages had high dominance and were indicative of reducing sediments, with many taxa common to other similar environments and no seep-endemic fauna, indicating transitional assemblages. Also similar to other cold seep areas, there were samples of authigenic carbonate, but rather than occurring as pavements or sedimentary concretions, these carbonates were restricted to patches on the shells of Axinulus antarcticus (Bivalvia, Thyasiridae), which is suggestive of microbe-metazoan interactions. PMID- 27703694 TI - Emotional arousal when watching drama increases pain threshold and social bonding. AB - Fiction, whether in the form of storytelling or plays, has a particular attraction for us: we repeatedly return to it and are willing to invest money and time in doing so. Why this is so is an evolutionary enigma that has been surprisingly underexplored. We hypothesize that emotionally arousing drama, in particular, triggers the same neurobiological mechanism (the endorphin system, reflected in increased pain thresholds) that underpins anthropoid primate and human social bonding. We show that, compared to subjects who watch an emotionally neutral film, subjects who watch an emotionally arousing film have increased pain thresholds and an increased sense of group bonding. PMID- 27703693 TI - A computational study of cancer hyperthermia based on vascular magnetic nanoconstructs. AB - The application of hyperthermia to cancer treatment is studied using a novel model arising from the fundamental principles of flow, mass and heat transport in biological tissues. The model is defined at the scale of the tumour microenvironment and an advanced computational scheme called the embedded multiscale method is adopted to solve the governing equations. More precisely, this approach involves modelling capillaries as one-dimensional channels carrying flow, and special mathematical operators are used to model their interaction with the surrounding tissue. The proposed computational scheme is used to analyse hyperthermic treatment of cancer based on systemically injected vascular magnetic nanoconstructs carrying super-paramagnetic iron oxide nanoparticles. An alternating magnetic field is used to excite the nanoconstructs and generate localized heat within the tissue. The proposed model is particularly adequate for this application, since it has a unique capability of incorporating microvasculature configurations based on physiological data combined with coupled capillary flow, interstitial filtration and heat transfer. A virtual tumour model is initialized and the spatio-temporal distribution of nanoconstructs in the vascular network is analysed. In particular, for a reference iron oxide concentration, temperature maps of several different hypothesized treatments are generated in the virtual tumour model. The observations of the current study might in future guide the design of more efficient treatments for cancer hyperthermia. PMID- 27703695 TI - US line-ups outperform UK line-ups. AB - In the USA and the UK, many thousands of police suspects are identified by eyewitnesses every year. Unfortunately, many of those suspects are innocent, which becomes evident when they are exonerated by DNA testing, often after having been imprisoned for years. It is, therefore, imperative to use identification procedures that best enable eyewitnesses to discriminate innocent from guilty suspects. Although police investigators in both countries often administer line up procedures, the details of how line-ups are presented are quite different and an important direct comparison has yet to be conducted. We investigated whether these two line-up procedures differ in terms of (i) discriminability (using receiver operating characteristic analysis) and (ii) reliability (using confidence-accuracy characteristic analysis). A total of 2249 participants watched a video of a crime and were later tested using either a six-person simultaneous photo line-up procedure (USA) or a nine-person sequential video line up procedure (UK). US line-up procedure yielded significantly higher discriminability and significantly higher reliability. The results do not pinpoint the reason for the observed difference between the two procedures, but they do suggest that there is much room for improvement with the UK line-up. PMID- 27703696 TI - A novel MC1R allele for black coat colour reveals the Polynesian ancestry and hybridization patterns of Hawaiian feral pigs. AB - Pigs (Sus scrofa) have played an important cultural role in Hawaii since Polynesians first introduced them in approximately AD 1200. Additional varieties of pigs were introduced following Captain Cook's arrival in Hawaii in 1778 and it has been suggested that the current pig population may descend primarily, or even exclusively, from European pigs. Although populations of feral pigs today are an important source of recreational hunting on all of the major islands, they also negatively impact native plants and animals. As a result, understanding the origins of these feral pig populations has significant ramifications for discussions concerning conservation management, identity and cultural continuity on the islands. Here, we analysed a neutral mitochondrial marker and a functional nuclear coat colour marker in 57 feral Hawaiian pigs. Through the identification of a new mutation in the MC1R gene that results in black coloration, we demonstrate that Hawaiian feral pigs are mostly the descendants of those originally introduced during Polynesian settlement, though there is evidence for some admixture. As such, extant Hawaiian pigs represent a unique historical lineage that is not exclusively descended from feral pigs of European origin. PMID- 27703697 TI - Acidification and gamma-aminobutyric acid independently alter kairomone-induced behaviour. AB - Exposure to high pCO2 or low pH alters sensation and behaviour in many marine animals. We show that crab larvae lose their ability to detect and/or process predator kairomones after exposure to low pH over a time scale relevant to diel pH cycles in coastal environments. Previous work suggests that acidification affects sensation and behaviour through altered neural function, specifically the action of gamma-aminobutyric acid (GABA), because a GABA antagonist, gabazine, restores the original behaviour. Here, however, gabazine resulted in a loss of kairomone detection/processing, regardless of pH. Our results also suggest that GABAergic signalling is necessary for kairomone identification in these larvae. Hence, the mechanism for the observed pH effect varies from the original GABA hypothesis. Furthermore, we suggest that this pH effect is adaptive under diel cycling pH. PMID- 27703698 TI - Seabird diving behaviour reveals the functional significance of shelf-sea fronts as foraging hotspots. AB - Oceanic fronts are key habitats for a diverse range of marine predators, yet how they influence fine-scale foraging behaviour is poorly understood. Here, we investigated the dive behaviour of northern gannets Morus bassanus in relation to shelf-sea fronts. We GPS (global positioning system) tracked 53 breeding birds and examined the relationship between 1901 foraging dives (from time-depth recorders) and thermal fronts (identified via Earth Observation composite front mapping) in the Celtic Sea, Northeast Atlantic. We (i) used a habitat-use availability analysis to determine whether gannets preferentially dived at fronts, and (ii) compared dive characteristics in relation to fronts to investigate the functional significance of these oceanographic features. We found that relationships between gannet dive probabilities and fronts varied by frontal metric and sex. While both sexes were more likely to dive in the presence of seasonally persistent fronts, links to more ephemeral features were less clear. Here, males were positively correlated with distance to front and cross-front gradient strength, with the reverse for females. Both sexes performed two dive strategies: shallow V-shaped plunge dives with little or no active swim phase (92% of dives) and deeper U-shaped dives with an active pursuit phase of at least 3 s (8% of dives). When foraging around fronts, gannets were half as likely to engage in U-shaped dives compared with V-shaped dives, independent of sex. Moreover, V-shaped dive durations were significantly shortened around fronts. These behavioural responses support the assertion that fronts are important foraging habitats for marine predators, and suggest a possible mechanistic link between the two in terms of dive behaviour. This research also emphasizes the importance of cross-disciplinary research when attempting to understand marine ecosystems. PMID- 27703699 TI - Temporal regularity increases with repertoire complexity in the Australian pied butcherbird's song. AB - Music maintains a characteristic balance between repetition and novelty. Here, we report a similar balance in singing performances of free-living Australian pied butcherbirds. Their songs include many phrase types. The more phrase types in a bird's repertoire, the more diverse the singing performance can be. However, without sufficient temporal organization, avian listeners may find diverse singing performances difficult to perceive and memorize. We tested for a correlation between the complexity of song repertoire and the temporal regularity of singing performance. We found that different phrase types often share motifs (notes or stereotyped groups of notes). These shared motifs reappeared in strikingly regular temporal intervals across different phrase types, over hundreds of phrases produced without interruption by each bird. We developed a statistical estimate to quantify the degree to which phrase transition structure is optimized for maximizing the regularity of shared motifs. We found that transition probabilities between phrase types tend to maximize regularity in the repetition of shared motifs, but only in birds of high repertoire complexity. Conversely, in birds of low repertoire complexity, shared motifs were produced with less regularity. The strong correlation between repertoire complexity and motif regularity suggests that birds possess a mechanism that regulates the temporal placement of shared motifs in a manner that takes repertoire complexity into account. We discuss alternative musical, mechanistic and ecological explanations to this effect. PMID- 27703700 TI - Enhancing endorsement of scientific inquiry increases support for pro-environment policies. AB - Pro-environment policies require public support and engagement, but in countries such as the USA, public support for pro-environment policies remains low. Increasing public scientific literacy is unlikely to solve this, because increased scientific literacy does not guarantee increased acceptance of critical environmental issues (e.g. that climate change is occurring). We distinguish between scientific literacy (basic scientific knowledge) and endorsement of scientific inquiry (perceiving science as a valuable way of accumulating knowledge), and examine the relationship between people's endorsement of scientific inquiry and their support for pro-environment policy. Analysis of a large, publicly available dataset shows that support for pro-environment policies is more strongly related to endorsement of scientific inquiry than to scientific literacy among adolescents. An experiment demonstrates that a brief intervention can increase support for pro-environment policies via increased endorsement of scientific inquiry among adults. Public education about the merits of scientific inquiry may facilitate increased support for pro-environment policies. PMID- 27703701 TI - Energy-based constitutive modelling of local material properties of canine aortas. AB - This study aims at determining the in vitro anisotropic mechanical behaviour of canine aortic tissue. We specifically focused on spatial variations of these properties along the axis of the vessel. We performed uniaxial stretch tests on canine aortic samples in both circumferential and longitudinal directions, as well as histological examinations to derive the tissue's fibre orientations. We subsequently characterized a constitutive model that incorporates both phenomenological and structural elements to account for macroscopic and microstructural behaviour of the tissue. We showed the two fibre families were oriented at similar angles with respect to the aorta's axis. We also found significant changes in mechanical behaviour of the tissue as a function of axial position from proximal to distal direction: the fibres become more aligned with the aortic axis from 46 degrees to 30 degrees . Also, the linear shear modulus of media decreased as we moved distally along the aortic axis from 139 to 64 kPa. These changes derived from the parameters in the nonlinear constitutive model agreed well with the changes in tissue structure. In addition, we showed that isotropic contribution, carried by elastic lamellae, to the total stress induced in the tissue decreases at higher stretch ratios, whereas anisotropic stress, carried by collagen fibres, increases. The constitutive models can be readily used to design computational models of tissue deformation during physiological loading cycles. The findings of this study extend the understanding of local mechanical properties that could lead to region-specific diagnostics and treatment of arterial diseases. PMID- 27703702 TI - Colour vision and background adaptation in a passerine bird, the zebra finch (Taeniopygia guttata). AB - Today, there is good knowledge of the physiological basis of bird colour vision and how mathematical models can be used to predict visual thresholds. However, we still know only little about how colour vision changes between different viewing conditions. This limits the understanding of how colour signalling is configured in habitats where the light of the illumination and the background may shift dramatically. I examined how colour discrimination in zebra finch (Taeniopygia guttata) is affected by adaptation to different backgrounds. I trained finches in a two-alternative choice task, to choose between red discs displayed on backgrounds with different colours. I found that discrimination thresholds correlate with stimulus contrast to the background. Thresholds are low, and in agreement with model predictions, for a background with a red colour similar to the discs. For the most contrasting green background, thresholds are about five times higher than this. Subsequently, I trained the finches for the detection of single discs on a grey background. Detection thresholds are about 2.5 to 3 times higher than discrimination thresholds. This study demonstrates close similarities in human and bird colour vision, and the quantitative data offer a new possibility to account for shifting viewing conditions in colour vision models. PMID- 27703703 TI - The natural selection of bad science. AB - Poor research design and data analysis encourage false-positive findings. Such poor methods persist despite perennial calls for improvement, suggesting that they result from something more than just misunderstanding. The persistence of poor methods results partly from incentives that favour them, leading to the natural selection of bad science. This dynamic requires no conscious strategizing no deliberate cheating nor loafing-by scientists, only that publication is a principal factor for career advancement. Some normative methods of analysis have almost certainly been selected to further publication instead of discovery. In order to improve the culture of science, a shift must be made away from correcting misunderstandings and towards rewarding understanding. We support this argument with empirical evidence and computational modelling. We first present a 60-year meta-analysis of statistical power in the behavioural sciences and show that power has not improved despite repeated demonstrations of the necessity of increasing power. To demonstrate the logical consequences of structural incentives, we then present a dynamic model of scientific communities in which competing laboratories investigate novel or previously published hypotheses using culturally transmitted research methods. As in the real world, successful labs produce more 'progeny,' such that their methods are more often copied and their students are more likely to start labs of their own. Selection for high output leads to poorer methods and increasingly high false discovery rates. We additionally show that replication slows but does not stop the process of methodological deterioration. Improving the quality of research requires change at the institutional level. PMID- 27703704 TI - Colour thresholds in a coral reef fish. AB - Coral reef fishes are among the most colourful animals in the world. Given the diversity of lifestyles and habitats on the reef, it is probable that in many instances coloration is a compromise between crypsis and communication. However, human observation of this coloration is biased by our primate visual system. Most animals have visual systems that are 'tuned' differently to humans; optimized for different parts of the visible spectrum. To understand reef fish colours, we need to reconstruct the appearance of colourful patterns and backgrounds as they are seen through the eyes of fish. Here, the coral reef associated triggerfish, Rhinecanthus aculeatus, was tested behaviourally to determine the limits of its colour vision. This is the first demonstration of behavioural colour discrimination thresholds in a coral reef species and is a critical step in our understanding of communication and speciation in this vibrant colourful habitat. Fish were trained to discriminate between a reward colour stimulus and series of non-reward colour stimuli and the discrimination thresholds were found to correspond well with predictions based on the receptor noise limited visual model and anatomy of the eye. Colour discrimination abilities of both reef fish and a variety of animals can therefore now be predicted using the parameters described here. PMID- 27703705 TI - Mathematical toy model inspired by the problem of the adaptive origins of the sexual orientation continuum. AB - Same-sex sexual behaviour is ubiquitous in the animal kingdom, but its adaptive origins remain a prominent puzzle. Here, I suggest the possibility that same-sex sexual behaviour arises as a consequence of the competition between an evolutionary drive for a wide diversity in traits, which improves the adaptability of a population, and a drive for sexual dichotomization of traits, which promotes opposite-sex attraction and increases the rate of reproduction. This trade-off is explored via a simple mathematical 'toy model'. The model exhibits a number of interesting features and suggests a simple mathematical form for describing the sexual orientation continuum. PMID- 27703707 TI - Packing and deploying Soft Origami to and from cylindrical volumes with application to automotive airbags. AB - Packing soft-sheet materials of approximately zero bending stiffness using Soft Origami (origami patterns applied to soft-sheet materials) into cylindrical volumes and their deployment via mechanisms or internal pressure (inflation) is of interest in fields including automobile airbags, deployable heart stents, inflatable space habitats, and dirigible and parachute packing. This paper explores twofold patterns, the 'flasher' and the 'inverted-cone fold', for packing soft-sheet materials into cylindrical volumes. Two initial packing methods and mechanisms are examined for each of the flasher and inverted-cone fold patterns. An application to driver's side automobile airbags is performed, and deployment tests are completed to compare the influence of packing method and origami pattern on deployment performance. Following deployment tests, two additional packing methods for the inverted-cone fold pattern are explored and applied to automobile airbags. It is shown that modifying the packing method (using different methods to impose the same base pattern on the soft-sheet material) can lead to different deployment performance. In total, two origami patterns and six packing methods are examined, and the benefits of using Soft Origami patterns and packing methods are discussed. Soft Origami is presented as a viable method for efficiently packing soft-sheet materials into cylindrical volumes. PMID- 27703706 TI - The secret life of ground squirrels: accelerometry reveals sex-dependent plasticity in above-ground activity. AB - The sexes differ in how and when they allocate energy towards reproduction, but how this influences phenotypic plasticity in daily activity patterns is unclear. Here, we use collar-mounted light loggers and triaxial accelerometers to examine factors that affect time spent above ground and overall dynamic body acceleration (ODBA), an index of activity-specific energy expenditure, across the active season of free-living, semi-fossorial arctic ground squirrels (Urocitellus parryii). We found high day-to-day variability in time spent above ground and ODBA with most of the variance explained by environmental conditions known to affect thermal exchange. In both years, females spent more time below ground compared with males during parturition and early lactation; however, this difference was fourfold larger in the second year, possibly, because females were in better body condition. Daily ODBA positively correlated with time spent above ground in both sexes, but females were more active per unit time above ground. Consequently, daily ODBA did not differ between the sexes when females were early in lactation, even though females were above ground three to six fewer hours each day. Further, on top of having the additional burden of milk production, ODBA data indicate females also had fragmented rest patterns and were more active during late lactation. Our results indicate that sex differences in reproductive requirements can have a substantial influence on activity patterns, but the size of this effect may be dependent on capital resources accrued during gestation. PMID- 27703709 TI - Atypical residency of short-beaked common dolphins (Delphinus delphis) to a shallow, urbanized embayment in south-eastern Australia. AB - Short-beaked common dolphins (Delphinus delphis) are typically considered highly mobile, offshore delphinids. This study assessed the residency of a small community of short-beaked common dolphins in the shallow, urbanized Port Phillip Bay, south-eastern Australia. The ability to identify common dolphins by their dorsal fin markings and coloration using photo-identification was also investigated. Systematic and non-systematic boat surveys were undertaken between 2007 and 2014. Results showed that 13 adult common dolphins and their offspring inhabit Port Phillip Bay, of which 10 adults exhibit residency to the bay. The majority of these adults are reproductively active females, suggesting that female philopatry may occur in the community. Systematic surveys conducted between 2012 and 2014 revealed that the dolphins were found in a median water depth of 16 m and median distance of 2.2 km from the coast. The shallow, urbanized habitat of this resident common dolphin community is atypical for this species. As a result, these common dolphins face threats usually associated with inshore bottlenose dolphin communities. We suggest that the Port Phillip Bay common dolphin community is considered and managed separate to those outside the embayment and offshore to ensure the community's long-term viability and residency in the bay. PMID- 27703708 TI - The first iguanian lizard from the Mesozoic of Africa. AB - The fossil record shows that iguanian lizards were widely distributed during the Late Cretaceous. However, the biogeographic history and early evolution of one of its most diverse and peculiar clades (acrodontans) remain poorly known. Here, we present the first Mesozoic acrodontan from Africa, which also represents the oldest iguanian lizard from that continent. The new taxon comes from the Kem Kem Beds in Morocco (Cenomanian, Late Cretaceous) and is based on a partial lower jaw. The new taxon presents a number of features that are found only among acrodontan lizards and shares greatest similarities with uromastycines, specifically. In a combined evidence phylogenetic dataset comprehensive of all major acrodontan lineages using multiple tree inference methods (traditional and implied weighting maximum-parsimony, and Bayesian inference), we found support for the placement of the new species within uromastycines, along with Gueragama sulamericana (Late Cretaceous of Brazil). The new fossil supports the previously hypothesized widespread geographical distribution of acrodontans in Gondwana during the Mesozoic. Additionally, it provides the first fossil evidence of uromastycines in the Cretaceous, and the ancestry of acrodontan iguanians in Africa. PMID- 27703710 TI - A hybrid continuous-discrete method for stochastic reaction-diffusion processes. AB - Stochastic fluctuations in reaction-diffusion processes often have substantial effect on spatial and temporal dynamics of signal transductions in complex biological systems. One popular approach for simulating these processes is to divide the system into small spatial compartments assuming that molecules react only within the same compartment and jump between adjacent compartments driven by the diffusion. While the approach is convenient in terms of its implementation, its computational cost may become prohibitive when diffusive jumps occur significantly more frequently than reactions, as in the case of rapid diffusion. Here, we present a hybrid continuous-discrete method in which diffusion is simulated using continuous approximation while reactions are based on the Gillespie algorithm. Specifically, the diffusive jumps are approximated as continuous Gaussian random vectors with time-dependent means and covariances, allowing use of a large time step, even for rapid diffusion. By considering the correlation among diffusive jumps, the approximation is accurate for the second moment of the diffusion process. In addition, a criterion is obtained for identifying the region in which such diffusion approximation is required to enable adaptive calculations for better accuracy. Applications to a linear diffusion system and two nonlinear systems of morphogens demonstrate the effectiveness and benefits of the new hybrid method. PMID- 27703711 TI - Sustainable self-healing at ultra-low temperatures in structural composites incorporating hollow vessels and heating elements. AB - Self-healing composites are able to restore their properties automatically. Impressive healing efficiencies can be achieved when conditions are favourable. On the other hand, healing might not be possible under adverse circumstances such as very low ambient temperature. Here, we report a structural composite able to maintain its temperature to provide a sustainable self-healing capability-similar to that in the natural world where some animals keep a constant body temperature to allow enzymes to stay active. The composite embeds three-dimensional hollow vessels with the purpose of delivering and releasing healing agents, and a porous conductive element to provide heat internally to defrost and promote healing reactions. A healing efficiency over 100% at around -60 degrees C was obtained. The effects of the sheets on the interlaminar and tensile properties have been investigated experimentally. The proposed technique can be implemented in a majority of extrinsic self-healing composites to enable automatic recovery at ultra-low temperatures. PMID- 27703712 TI - Stretching the truth: length data highlight falsification of Japanese sperm whale catch statistics in the Southern Hemisphere. AB - Falsification of reports on Japanese catches of sperm whales (Physeter macrocephalus) is known to have occurred at both land whaling stations and in North Pacific factory fleets. Here, we conduct an analysis of pelagic sperm whale catches in the Southern Hemisphere: we compare true Soviet length data from the Yuri Dolgorukiy factory fleet during 1960-1975 to data for the same period reported to the International Whaling Commission (IWC) by Japan. Prior to implementation of the International Observer Scheme (IOS) in 1972, the Soviet fleet killed 5536 females, of which only 153 (2.8%) were at or above the minimum legal length of 11.6 m. During the same period, Japan killed 5799 females and reported that 5686 (98.5%) were of legal size, with 88.5% of the entire length distribution reported as being between 11.6 and 12.0 m. This unrealistic distribution, together with the fact that Japanese fleets were supposedly able to catch 37 times the number of legal-sized females as the Soviet fleet, indicates extensive falsification of catch data by Japan. Further evidence of misreporting is that females >11.5 m dropped to 9.1% of the Japanese catch after 1971, when the IOS made cheating much more difficult. That 99.6% of 10 433 males in the pre IOS catch were also reported to be of legal size, indicates that illegal catches were not confined to females. We caution that the Japanese sperm whale data in the IWC Catch Database are unreliable and should not be used in population assessments. The ease with which illegal catches were apparently made underscores the past failures of the IWC to effectively regulate whaling. PMID- 27703713 TI - Offspring sex preferences among patrilineal and matrilineal Mosuo in Southwest China revealed by differences in parity progression. AB - Son preference predominates in China, yet there are patterned exceptions to this rule. In this paper, we test whether lineality (patrilineal versus matrilineal inheritance and descent) is associated with son versus daughter preference among the ethnic Mosuo (Na) of Southwest China. Our results show (i) an increased probability of continued fertility among matrilineal women after having a son compared with a daughter and (ii) an increased probability of continued fertility among patrilineal women after having a daughter compared with a son. These results are consistent with son preference among patrilineal Mosuo and more muted daughter preference among the matrilineal Mosuo. Furthermore, we show (iii) the lowest probability of continued fertility at parity 2 once women have one daughter and one son across both systems, suggesting that preferences for at least one of each sex exist alongside preferences for the lineal sex. The Mosuo are the only known small-scale society in which two kinship systems distinguish sub-groups with many otherwise shared cultural characteristics. We discuss why this, in conjunction with differences in subsistence, may shed light on the evolutionary underpinnings of offspring sex preferences. PMID- 27703714 TI - Transition from one- to two-dimensional development facilitates maintenance of multicellularity. AB - Filamentous organisms represent an example where incomplete separation after cell division underlies the development of multicellular formations. With a view to understanding the evolution of more complex multicellular structures, we explore the transition of multicellular growth from one to two dimensions. We develop a computational model to simulate multicellular development in populations where cells exhibit density-dependent division and death rates. In both the one- and two-dimensional contexts, multicellular formations go through a developmental cycle of growth and subsequent decay. However, the model shows that a transition to a higher dimension increases the size of multicellular formations and facilitates the maintenance of large cell clusters for significantly longer periods of time. We further show that the turnover rate for cell division and death scales with the number of iterations required to reach the stationary multicellular size at equilibrium. Although size and life cycles of multicellular organisms are affected by other environmental and genetic factors, the model presented here evaluates the extent to which the transition of multicellular growth from one to two dimensions contributes to the maintenance of multicellular structures during development. PMID- 27703715 TI - Disclosing the potential impact of placebo controls in antidepressant trials. AB - BACKGROUND: Although placebo-control clinical trials that withhold effective treatments can be permissible, how best to inform participants of the placebo design has received little attention. AIMS: To determine the effect of disclosing quantitative outcome estimates of individual treatment v. entering placebo control randomised control trial (RCT) on willingness to enrol in such an RCT. METHOD: We randomised 278 adult patients at a depression clinic to receive standard disclosure (n = 129) or enhanced (n = 149) quantitative outcome estimates (based on decision analysis) of individual treatment v. RCT, and assessed their willingness to enrol in the RCT. RESULTS: A greater proportion of those in the standard arm preferred enrolling in RCT (41.3% v. 23.8%, P = 0.002). Those in the standard arm preferred RCT more for direct benefit than altruism reasons, whereas the opposite was true in the enhanced arm. CONCLUSIONS: Disclosing the quantitative outcome implications of placebos may select for fewer but more altruistic participants.

AB - SUMMARY: Consecutive admissions of 214 women with borderline personality disorder were investigated for patterns of specific forms of self-harm and reported developmental experiences. Systematic examination of clinical notes found that 75% had previously reported a history of childhood sexual abuse. These women were more likely to self-harm, and in specific ways that may reflect their past experiences. Despite this, treatment within a dialectical behaviour therapy informed therapeutic community leads to relatively greater clinical gains than for those without a reported sexual abuse trauma history. Notably, greater behavioural and self-reported distress and dissociation were not found to predict poor clinical outcome. DECLARATION OF INTEREST: None.

AB - BACKGROUND: The association between childhood adversity and psychosis in adulthood is well established. However, genetic factors might confound or moderate this association. AIMS: Using a catchment-based case-control sample, we explored the main effects of, and interplay between, childhood adversity and family psychiatric history on the onset of psychosis. METHOD: Childhood adversity (parental separation and death, physical and sexual abuse) was assessed retrospectively in 224 individuals with a first presentation of psychosis and 256 community controls from South London, UK. Occurrence of psychotic and affective disorders in first-degree relatives was ascertained with the Family Interview for Genetic Studies (FIGS). RESULTS: Parental history of psychosis did not confound the association between childhood adversity and psychotic disorder. There was no evidence that childhood adversity and familial liability combined synergistically to increase odds of psychosis beyond the effect of each individually. CONCLUSIONS: Our results do not support the hypothesis that family psychiatric history amplifies the effect of childhood adversity on odds of psychosis. DECLARATION OF INTEREST: None.

PMID- 27703717 TI - Unrecognised psychopathology in patients with difficult asthma: major mental and personality disorders. AB - BACKGROUND: Difficult asthma is a severe subgroup of asthma in which the main feature is uncontrollability of symptoms. Psychopathology is suggested to be prominent in patients with difficult asthma and considered important in its treatment; however, the evidence is scarce. AIMS: To describe psychopathology in difficult asthma, both major mental and personality disorders, based on diagnostic interviews. METHOD: This study was conducted in a specialised asthma care centre. A total of 51 patients with difficult asthma were diagnosed at the start of the treatment programme using two structured clinical interviews for both major mental (SCID-I) and personality disorders (SCID-II) according to DSM IV-TR. RESULTS: About 55% of the patients with difficult asthma had a psychiatric disorder of which 89% was undiagnosed and untreated before being interviewed. About 49% had a minimum of one major mental disorder of which the cluster of anxiety disorders was the most common cluster of major mental disorders, followed by somatoform disorders. About 20% were diagnosed with a personality disorder. Of the 10 patients with a personality disorder, 9 had an obsessive-compulsive personality disorder. CONCLUSIONS: This study demonstrates that more than half of patients with difficult asthma had a psychiatric disorder of which 89% was unrecognised. This study highlights the importance of offering patients with difficult asthma a psychiatric diagnostic interview and/or a psychiatric consultation as part of their routine medical examination and provision of appropriate psychiatric treatment. Moreover, it highlights the urgency of further research into the role of psychopathology in the development of difficult asthma. DECLARATION OF INTEREST: None.

AB - BACKGROUND: The Short Obsessive-Compulsive Disorder Screener (SOCS) is recommended by the National Institute for Health and Care Excellence as a suitable and validated screening tool for 11- to 15-year olds. Despite its excellent sensitivity and specificity in detecting obsessive-compulsive disorder (OCD), it has limitations. AIMS: To empirically examine whether the SOCS is suitable for assessing OCD symptoms across a wide age range of children and adolescents and to provide new data about its psychometric properties. METHOD: Participants were 94 patients (9-19 years) with OCD, and 880 healthy controls. RESULTS: The results supported the SOCS' unidimensional factor structure and metric invariance across samples. It showed good reliability in terms of internal consistency and temporal stability. Furthermore, it had significantly high correlations with other OCD measures and an acceptable sensitivity and specificity for detecting OCD. CONCLUSIONS: The SOCS is a brief screening tool suitable for detecting OCD in children and adolescents. DECLARATION OF INTEREST: None.

PMID- 27703720 TI - Antipsychotics for the management of psychosis in Parkinson's disease: systematic review and meta-analysis. AB - BACKGROUND: Antipsychotics can exacerbate motor symptoms in Parkinson's disease psychosis. AIMS: To systematically review the literature on the efficacy and acceptability of antipsychotics for Parkinson's disease psychosis. METHOD: Randomised controlled trials comparing an antipsychotic with placebo were systematically reviewed. RESULTS: The final selection list included nine studies using quetiapine (3), clozapine (2), olanzapine (3) and pimavanserin (1). A narrative synthesis and meta-analyses (where appropriate) were presented for each antipsychotic. Clozapine demonstrated superiority over placebo in reducing psychotic symptoms. Quetiapine and olanzapine did not significantly improve psychotic symptoms. All three antipsychotics may exacerbate motor symptoms. Quetiapine studies were associated with high drop-out rates due to adverse events. Pimavanserin is a novel treatment that warrants further investigation. CONCLUSIONS: Further research is needed. Clozapine and pimavanserin appear to be a promising treatment for Parkinson's disease psychosis. DECLARATION OF INTEREST: None. COPYRIGHT AND USAGE: (c) The Royal College of Psychiatrists 2015.

PMID- 27703722 TI - Improving quality of care among patients hospitalised with schizophrenia: a nationwide initiative. AB - BACKGROUND: The effectiveness of systematic quality improvement initiatives in psychiatric care remains unclear. AIMS: To examine whether quality of care has changed following implementation of a systematic monitoring programme of hospital performance measures. METHOD: In a nationwide population-based cohort study, we identified 14 228 patients admitted to psychiatric departments between 2004 and 2011 from The Danish Schizophrenia Registry. The registry systematically monitors the adherence to guideline recommended processes of care. RESULTS: The overall proportion of all relevant recommended processes of care increased from 64 to 76% between 2004 and 2011. The adherence to individual processes of care increased over time, including assessment of psychopathology using a diagnostic interview (relative risk (RR): 2.01, 95% CI: 1.51-2.68), contact with relatives (RR: 1.44, 95% CI: 1.27-1.62), psychoeducation (RR: 1.33, 95% CI: 1.19-1.48), psychiatric aftercare (RR: 1.06, 95% CI: 1.01-1.11) and suicide risk assessment (RR: 1.31, 95% CI: 1.21-1.42). CONCLUSIONS: Quality of care improved from 2004 to 2011 among patients hospitalised with schizophrenia in Denmark. DECLARATION OF INTEREST: None.

PMID- 27703721 TI - Prevalence and correlates of explosive anger among pregnant and post-partum women in post-conflict Timor-Leste. AB - BACKGROUND: Little is known about explosive anger as a response pattern among pregnant and post-partum women in conflict-affected societies. AIMS: To investigate the prevalence and correlates of explosive anger among this population in Timor-Leste. METHOD: We assessed traumatic events, intimate partner violence, an index of adversity, explosive anger, psychological distress and post traumatic stress disorder among 427 women (257 in the second trimester of pregnancy, 170 who were 3-6 months post-partum) residing in two districts of Timor-Leste (response >99%). RESULTS: Two-fifths (43.6%) had explosive anger. Levels of functional impairment were related to frequency of explosive anger episodes. Explosive anger was associated with age (>35 years), being married, low levels of education, being employed, traumatic event count, ongoing adversity and intimate partner violence. CONCLUSIONS: A combination of social programmes and novel psychological therapies may assist in reducing severe anger among pregnant and post-partum women in conflict-affected countries such as Timor-Leste.

PMID- 27703723 TI - Excess cause-specific mortality in out-patients with personality disorder. AB - SUMMARY: Personality disorders (PDs) are associated with increased overall mortality. In patients hospitalised with a principal diagnosis of PD, this is observed for all clusters and for natural as well as unnatural causes of death. Data from Swedish nationwide registers were used to assess whether this was also true for the majority of patients diagnosed with PDs not severe enough to lead to hospitalisation. There was an increased mortality in all clusters, and for natural as well as unnatural death, also in patients treated as out-patients only, although not to the same extent as in those hospitalised.

PMID- 27703724 TI - Clinical effectiveness of a skills training intervention for caregivers in improving patient and caregiver health following in-patient treatment for severe anorexia nervosa: pragmatic randomised controlled trial. AB - BACKGROUND: Families express a need for information to support people with severe anorexia nervosa. AIMS: To examine the impact of the addition of a skills training intervention for caregivers (Experienced Caregivers Helping Others, ECHO) to standard care. METHOD: Patients over the age of 12 (mean age 26 years, duration 72 months illness) with a primary diagnosis of anorexia nervosa and their caregivers were recruited from 15 in-patient services in the UK. Families were randomised to ECHO (a book, DVDs and five coaching sessions per caregiver) or treatment as usual. Patient (n=178) and caregiver (n=268) outcomes were measured at discharge and 6 and 12 months after discharge. RESULTS: Patients with caregivers in the ECHO group had reduced eating disorder psychopathology (EDE-Q) and improved quality of life (WHO-Quol; both effects small) and reduced in patient bed days (7-12 months post-discharge). Caregivers in the ECHO group had reduced burden (Eating Disorder Symptom Impact Scale, EDSIS), expressed emotion (Family Questionnaire, FQ) and time spent caregiving at 6 months but these effects were diminished at 12 months. CONCLUSIONS: Small but sustained improvements in symptoms and bed use are seen in the intervention group. Moreover, caregivers were less burdened and spent less time providing care. Caregivers had most benefit at 6 months suggesting that booster sessions, perhaps jointly with the patients, may be needed to maintain the effect. Sharing skills and information with caregivers may be an effective way to improve outcomes. This randomised controlled trial (RCT) was registered with Current Controlled Trials ISRCTN06149665.

PMID- 27703725 TI - Treatment of clozapine-associated obesity and diabetes with exenatide (CODEX) in adults with schizophrenia: study protocol for a pilot randomised controlled trial. AB - BACKGROUND: Clozapine causes significant metabolic disturbances including obesity and type 2 diabetes. Recent evidence that reduced glucagon-like-peptide-1 (GLP-1) may contribute to aetiology of clozapine-associated metabolic dysregulation suggests a potential therapeutic role for GLP-1 agonists. METHOD: This open label, pilot randomised controlled trial evaluates the effect of exenatide in clozapine-treated obese adults who have schizophrenia, with or without poorly controlled diabetes. Sixty out-patients will be randomised to once weekly extended release exenatide or treatment as usual for 24 weeks. AIMS: To evaluate the feasibility of larger studies regarding methodology, acceptability, tolerability and estimate efficacy for glycaemic control or weight loss. Secondary outcomes are psychosis severity and metabolic parameters. CONCLUSIONS: This is the first trial investigating GLP-1 agonists for glycaemic control and weight loss in clozapine-treated patients with either diabetes or obesity. Clozapine-associated obesity and diabetes with exenatide (CODEX) will provide proof-of-concept empirical evidence addressing whether this novel treatment is practical and worthy of further investigation.

PMID- 27703727 TI - The role of peri-traumatic stress and disruption distress in predicting post traumatic stress disorder symptoms following exposure to a natural disaster. AB - BACKGROUND: Few studies have examined the contribution of specific disaster related experiences to post-traumatic stress disorder (PTSD) symptoms. AIMS: To examine the roles of peri-traumatic stress and distress due to lingering disaster related disruption in explaining linkages between disaster exposure and PTSD symptoms among a cohort exposed to the 2010-2011 Canterbury (New Zealand) earthquakes. METHOD: Structural equation models were fitted to data obtained from the Christchurch Health and Development Study at age 35 (n=495), 20-24 months following the onset of the disaster. Measures included: earthquake exposure, peri traumatic stress, disruption distress and PTSD symptoms. RESULTS: The associations between earthquake exposure and PTSD symptoms were explained largely by the experience of peri-traumatic stress during the earthquakes (beta=0.189, P<0.0001) and disruption distress following the earthquakes (beta=0.105, P<0.0001). CONCLUSIONS: The results suggest the importance of minimising post event disruption distress following exposure to a natural disaster. DECLARATION OF INTEREST: None.

PMID- 27703726 TI - Childhood IQ and risk of bipolar disorder in adulthood: prospective birth cohort study. AB - BACKGROUND: Intellectual ability may be an endophenotypic marker for bipolar disorder. AIMS: Within a large birth cohort, we aimed to assess whether childhood IQ (including both verbal IQ (VIQ) and performance IQ (PIQ) subscales) was predictive of lifetime features of bipolar disorder assessed in young adulthood. METHOD: We used data from the Avon Longitudinal Study of Parents and Children (ALSPAC), a large UK birth cohort, to test for an association between measures of childhood IQ at age 8 years and lifetime manic features assessed at age 22-23 years using the Hypomania Checklist-32 (HCL-32; n=1881 individuals). An ordinary least squares linear regression model was used, with normal childhood IQ (range 90-109) as the referent group. We adjusted analyses for confounding factors, including gender, ethnicity, handedness, maternal social class at recruitment, maternal age, maternal history of depression and maternal education. RESULTS: There was a positive association between IQ at age 8 years and lifetime manic features at age 22-23 years (Pearson's correlation coefficient 0.159 (95% CI 0.120-0.198), P>0.001). Individuals in the lowest decile of manic features had a mean full-scale IQ (FSIQ) which was almost 10 points lower than those in the highest decile of manic features: mean FSIQ 100.71 (95% CI 98.74-102.6) v. 110.14 (95% CI 107.79-112.50), P>0.001. The association between IQ and manic features was present for FSIQ, VIQ and for PIQ but was strongest for VIQ. CONCLUSIONS: A higher childhood IQ score, and high VIQ in particular, may represent a marker of risk for the later development of bipolar disorder. This finding has implications for understanding of how liability to bipolar disorder may have been selected through generations. It will also inform future genetic studies at the interface of intelligence, creativity and bipolar disorder and is relevant to the developmental trajectory of bipolar disorder. It may also improve approaches to earlier detection and treatment of bipolar disorder in adolescents and young adults. DECLARATION OF INTEREST: None.

PMID- 27703728 TI - Self-harm and suicidal acts: a suitable case for treatment of impulsivity-driven behaviour with repetitive transcranial magnetic stimulation (rTMS). AB - SUMMARY: Suicidal thinking, self-harm and suicidal acts are common, although determining their precise prevalence is complex. Epidemiological work has identified a number of associated demographic and clinical factors, though, with the exception of past acts of self-harm, these are non-specific and weak future predictors. There is a critical need shift focus from managing 'suicidality-by proxy' through general mental health treatments, to better understand the neuropsychology and neurophysiology of such behaviour to guide targeted interventions. The model of the cognitive control of emotion (MCCE) offers such a paradigm, with an underlying pan-diagnostic pathophysiology of a hypoactive prefrontal cortex failing to suitably inhibit an overactive threat-responding limbic system. The result is a phenotype - from any number of causative gene environment interactions - primed to impulsively self-harm. We argue that such neural dysconnectivity is open to potential therapeutic modification from repetitive transcranial magnetic stimulation (rTMS). The current evidence base for this is undoubtedly extremely limited, but the societal and clinical burden self-harm and suicide pose warrants such investigation.

PMID- 27703729 TI - Psychological distress among tsunami refugees from the Great East Japan earthquake. AB - BACKGROUND: The 2011 Great Japan tsunami and nuclear leaks displaced 300 000 people, but there are no large studies of psychological distress suffered by these refugees. AIMS: To provide a first assessment of major factors associated with distress and dysfunctional behaviour following the disasters. METHOD: All refugee families living in Miyagi were sent a questionnaire 10-12 months after the disasters. 21 981 participants (73%) returned questionnaires. Questions assessed psychological distress (Kessler Psychological Distress Scale, K6), dysfunctional behaviours, demographics, event exposure, change in physical activity, household visitors and emotional support. RESULTS: Nine percent scored 13+ on the K6 indicating risk of severe mental illness. Psychological distress was greater among Fukushima refugees. Demographic variables, family loss, illness history and change in physical activity were associated with psychological distress and dysfunctional behaviours. Associations between psychological distress and dysfunction and visitors/supporters depended on relation to supporter. CONCLUSIONS: Practitioners need to recognise existing disease burden, community histories and family roles when intervening following disasters. DECLARATION OF INTEREST: None.

AB - BACKGROUND: Empirical studies of rationality (syllogisms) in patients with schizophrenia have obtained different results. One study found that patients reason more logically if the syllogism is presented through an unusual content. AIMS: To explore syllogism-based rationality in schizophrenia. METHOD: Thirty eight first-admitted patients with schizophrenia and 38 healthy controls solved 29 syllogisms that varied in presentation content (ordinary v. unusual) and validity (valid v. invalid). Statistical tests were made of unadjusted and adjusted group differences in models adjusting for intelligence and neuropsychological test performance. RESULTS: Controls outperformed patients on all syllogism types, but the difference between the two groups was only significant for valid syllogisms presented with unusual content. However, when adjusting for intelligence and neuropsychological test performance, all group differences became non-significant. CONCLUSIONS: When taking intelligence and neuropsychological performance into account, patients with schizophrenia and controls perform similarly on syllogism tests of rationality.

PMID- 27703731 TI - Serotonin transporter polymorphism (5HTTLPR), severe childhood abuse and depressive symptom trajectories in adulthood. AB - BACKGROUND: Cross-sectional studies suggest that the serotonin transporter promoter region polymorphism (5-HTT gene-linked polymorphic region, 5HTTLPR) moderates the relationship between childhood abuse and major depressive disorder. AIMS: To examine whether the 5HTTLPR polymorphism moderates the effect childhood abuse has on 5-year depressive symptom severity trajectories in adulthood. METHOD: At 5-year follow-up, DNA from 333 adult primary care attendees was obtained and genotyped for the 5HTTLPR polymorphism. Linear mixed models were used to test for a genotype * childhood abuse interaction effect on 5-year depressive symptom severity trajectories. RESULTS: After covariate adjustment, homozygous s allele carriers with a history of severe childhood abuse had significantly greater depressive symptom severity at baseline compared with those without a history of severe childhood abuse and this effect persisted throughout the 5-year period of observation. CONCLUSIONS: The 5HTTLPR s/s genotype robustly moderates the effects of severe childhood abuse on depressive symptom severity trajectories in adulthood. DECLARATION OF INTEREST: None.

PMID- 27703734 TI - Changes in diagnosis rates and behavioural traits of autism spectrum disorder over time. AB - BACKGROUND: The increased proportion of UK children diagnosed with autism spectrum disorder (ASD) has been attributed to improved identification, rather than true increase in incidence. AIM: To explore whether the proportion of children with diagnosis of ASD and/or the proportion with associated behavioural traits had increased over a 10-year period. METHOD: A cross-cohort comparison using regression to compare prevalence of diagnosis and behavioural traits over time. Participants were children aged 7 years assessed in 1998/1999 (n=8139) and 2007/2008 (n=13 831). RESULTS: During 1998/1999, 1.09% (95% CI 0.86-1.37) of children were reported as having ASD diagnosis compared with 1.68% (95% CI 1.42 2.00) in 2007/2008: risk ratio (RR)=1.55 (95% CI 1.17-2.06), P=0.003. The proportion of children in the population with behavioural traits associated with ASD was also larger in the later cohort: RR=1.61 (95% CI 1.35-1.92), P<0.001. Increased odds of diagnosis at the later time point was partially accounted for by adjusting for the increased proportion of children with ASD-type traits. CONCLUSIONS: Increased ASD diagnosis may partially reflect increase in rates of behaviour associated with ASD and/or greater parent/teacher recognition of associated behaviours.

PMID- 27703735 TI - Question use in child mental health assessments and the challenges of listening to families. AB - BACKGROUND: The mental health assessment is a fundamental aspect of clinical practice and central to this is the use of questions. AIMS: To investigate the frequency and type of questions utilised within a child mental health assessment. METHOD: The data consisted of 28 naturally occurring assessments from a UK child and adolescent mental health service. Data were analysed using quantitative and qualitative content analysis to determine frequencies and question type. RESULTS: Results indicated a total of 9086 questions in 41 h across the 28 clinical encounters. This equated to a mean of 3.7 questions per minute. Four types of questions were identified; yes-no interrogatives, wh-prefaced questions, declarative questions and tag questions. CONCLUSIONS: The current format of questioning may impede the opportunity for families to fully express their particular concerns and this has implications for service delivery and training.

PMID- 27703736 TI - Ventral striatum dysfunction in children and adolescents with reactive attachment disorder: functional MRI study. AB - BACKGROUND: Child maltreatment is a major risk factor for psychopathology, including reactive attachment disorder (RAD). AIMS: To examine whether neural activity during reward processing was altered in children and adolescents with RAD. METHOD: Sixteen children and adolescents with RAD and 20 typically developing (TD) individuals performed tasks with high and low monetary rewards while undergoing functional magnetic resonance imaging. RESULTS: Significantly reduced activity in the caudate and nucleus accumbens was observed during the high monetary reward condition in the RAD group compared with the TD group (P=0.015, family-wise error-corrected cluster level). Significant negative correlations between bilateral striatal activity and avoidant attachment were observed in the RAD and TD groups. CONCLUSIONS: Striatal neural reward activity in the RAD group was markedly decreased. The present results suggest that dopaminergic dysfunction occurs in the striatum of children and adolescents with RAD, leading towards potential future risks for psychopathology.

PMID- 27703737 TI - Cortical thickness and sulcal depth: insights on development and psychopathology in paediatric epilepsy. AB - BACKGROUND: The relationship between cortical thickness (CThick) and sulcal depth (SDepth) changes across brain regions during development. Epilepsy youth have CThick and SDepth abnormalities and prevalent psychiatric disorders. AIMS: This study compared the CThick-SDepth relationship in children with focal epilepsy with typically developing children (TDC) and the role played by seizure and psychopathology variables. METHOD: A surface-based, computational high-resolution three-dimesional (3D) magnetic resonance image analytic technique compared regional CThick-SDepth relationships in 42 participants with focal epilepsy and 46 TDC (6-16 years) imaged in a 1.5 Tesla scanner. Psychiatric interviews administered to each participant yielded psychiatric diagnoses. Parents provided seizure-related information. RESULTS: The TDC group alone demonstrated a significant negative medial fronto-orbital CThick-SDepth correlation. Focal epilepsy participants with but not without psychiatric diagnoses showed significant positive pre-central and post-central CThick-SDepth associations not found in TDC. Although the history of prolonged seizures was significantly associated with the post-central CThick-SDepth correlation, it was unrelated to the presence/absence of psychiatric diagnoses. CONCLUSIONS: Abnormal CThick SDepth pre-central and post-central associations might be a psychopathology biomarker in paediatric focal epilepsy. DECLARATION INTEREST: None.

PMID- 27703738 TI - An exploration of testosterone levels in patients with bipolar disorder. AB - BACKGROUND: Testosterone influences well-being, mood and cognition and may play a role in the pathophysiology of bipolar disorder. AIM: To examine testosterone levels in patients with bipolar disorder compared with healthy controls. METHOD: We examined baseline total testosterone levels and current depression scores in male and female patients with bipolar disorder and mild to moderate depression and healthy controls. RESULTS: A significant interaction between diagnosis and gender was observed (F(2,97)=9.791, P=0.002). Testosterone levels were significantly lower for male patients with bipolar disorder compared with male controls (P=0.001). Women with bipolar disorder had significantly higher testosterone levels than female controls (P=0.03). CONCLUSIONS: Disturbances in testosterone levels may represent an important neurobiological abnormality in bipolar disorder and may differ by gender. If these findings are confirmed, the use of gender appropriate treatment strategies for the normalisation of testosterone levels in bipolar disorder depression should be further explored.

PMID- 27703739 TI - Alterations in dorsal and ventral posterior cingulate connectivity in APOE epsilon4 carriers at risk of Alzheimer's disease. AB - BACKGROUND: Recent evidence suggests that exercise plays a role in cognition and that the posterior cingulate cortex (PCC) can be divided into dorsal and ventral subregions based on distinct connectivity patterns. AIMS: To examine the effect of physical activity and division of the PCC on brain functional connectivity measures in subjective memory complainers (SMC) carrying the epsilon 4 allele of apolipoprotein E (APOE epsilon4) allele. METHOD: Participants were 22 SMC carrying the APOE epsilon4 allele (epsilon4+; mean age 72.18 years) and 58 SMC non-carriers (epsilon4-; mean age 72.79 years). Connectivity of four dorsal and ventral seeds was examined. Relationships between PCC connectivity and physical activity measures were explored. RESULTS: epsilon4+ individuals showed increased connectivity between the dorsal PCC and dorsolateral prefrontal cortex, and the ventral PCC and supplementary motor area (SMA). Greater levels of physical activity correlated with the magnitude of ventral PCC-SMA connectivity. CONCLUSIONS: The results provide the first evidence that epsilon4+ individuals at increased risk of cognitive decline show distinct alterations in dorsal and ventral PCC functional connectivity.

It is unclear whether treatment in prison can influence criminal behaviour subsequent to release. AIMS: To investigate whether treatment in prison can delay time to reoffending. METHOD: Our sample consisted of 1717 adult prisoners in England and Wales convicted of a serious violent or sexual offence. We used Cox regression to investigate the effects of treatment received in prison on associations between mental illness and time to first reconviction following release. RESULTS: Prisoners with current symptoms of schizophrenia reoffended quicker following release. Nevertheless, treatment with medication significantly delayed time to violence (18% reduction). Treatment for substance dependence delayed violent and non-violent reoffending among prisoners with drug induced psychosis. CONCLUSIONS: Identifying prisoners with psychosis and administering treatment in prison have important protective effects against reoffending. Repeated screening with improved accuracy in identification is necessary to prevent cases being missed. DECLARATION OF INTEREST: None.

PMID- 27703741 TI - Psychiatric intervention and repeated admission to emergency centres due to drug overdose. AB - BACKGROUND: Repeated drug overdose is a major risk factor for suicide. Data are lacking on the effect of psychiatric intervention on preventing repeated drug overdose. AIMS: To investigate whether psychiatric intervention was associated with reduced readmission to emergency centres due to drug overdose. METHOD: Using a Japanese national in-patient database, we identified patients who were first admitted to emergency centres for drug overdose in 2010-2012. We used propensity score matching for patient and hospital factors to compare readmission rates between intervention (patients undergoing psychosocial assessment) and unexposed groups. RESULTS: Of 29 564 eligible patients, 13 035 underwent psychiatric intervention. In the propensity-matched 7938 pairs, 1304 patients were readmitted because of drug overdose. Readmission rate was lower in the intervention than in the unexposed group (7.3% v. 9.1% respectively, P<0.001). CONCLUSIONS: Psychiatric intervention was associated with reduced readmission in patients who had taken a drug overdose. DECLARATION OF INTEREST: None.

AB - SUMMARY: Since the proposition of the social integration theory by Emile Durkheim, macro-sociological changes have been speculated to affect suicide rates. This study investigates the effect of the First World War on Irish suicide rates. We applied an interrupted time series design of 1864-1921 annual Irish suicide rates. The 1864-1913 suicide rates exhibited a slow-rising trend with a sharp decline from the year 1914 onwards. The odds for death by suicide for males during the 1914-1918 period was 0.811 (95% CI 0.768-0.963). Irish rates of suicide were significantly reduced during the First World War, most notably for males. DECLARATION OF INTEREST: None. COPYRIGHT AND USAGE: (c) 2015 The Royal College of Psychiatrists.

PMID- 27703743 TI - Paediatric bipolar disorder: international comparisons of hospital discharge rates 2000-2010. AB - BACKGROUND: Controversy surrounds the diagnosis and prevalence of paediatric bipolar disorder, with estimates varying considerably between countries. AIMS: To determine the international hospital discharge rates for paediatric bipolar disorder compared with all other psychiatric diagnoses. METHOD: We used national data-sets from 2000 to 2010 from England, Australia, New Zealand, the USA and Germany. RESULTS: For those aged under 20 years, the discharge rates for paediatric bipolar disorder per 100 000 population were: USA 95.6, Australia 11.7, New Zealand 6.3, Germany 1.5 and England 0.9. The most marked divergence in discharge rates was in 5- to 9-year-olds: USA 27, New Zealand 0.22, Australia 0.14, Germany 0.03 and England 0.00. CONCLUSIONS: The disparity between US and other discharge rates for paediatric bipolar disorder is markedly greater than the variation for child psychiatric discharge rates overall, and for adult rates of bipolar disorder. This suggests there may be differing diagnostic practices for paediatric bipolar disorder in the USA. DECLARATION OF INTEREST: None. COPYRIGHT AND USAGE: (c) 2015 The Royal College of Psychiatrists.

PMID- 27703746 TI - Psychiatric hospital treatment of children and adolescents in New South Wales, Australia: 12-year trends. AB - BACKGROUND: It is preferable that children and adolescents requiring in-patient care for mental health problems are managed in age-appropriate facilities. To achieve this, nine specialist Child and Adolescent Mental Health Services (CAMHS) in-patient units have been commissioned in New South Wales (NSW) since 2002. AIMS: To examine trends in child and adolescent in-patient admissions since the opening of these CAMHS units. METHOD: Analysis of separation data for under 18 year-olds to CAMHS, adult mental health and paediatric units for the period 2002 to 2013 in NSW, comparing districts with and without specialist CAMHS units. RESULTS: Separations from CAMHS, adult and paediatric units rose with time, but there was no interaction between time and health district type (with/without CAMHS unit). Five of eight health districts experienced increased separations of under 18-year-olds from adult units in the year of opening a CAMHS unit. Separations from related paediatric units increased in three of seven health districts. CONCLUSIONS: Opening CAMHS units may be followed by a temporary increase in separations of young people from adult units, but it does not influence the flow of patients to non-CAMHS facilities in the longer term.

PMID- 27703744 TI - Adjunctive aripiprazole in risperidone-induced hyperprolactinaemia: double-blind, randomised, placebo-controlled trial. AB - BACKGROUND: Hyperprolactinaemia is a troublesome side-effect of treatment with antipsychotics. AIMS: This double-blind, placebo-controlled study aimed at examining the effect of adjunctive treatment with 10 mg aripiprazole on prolactin levels and sexual side-effects in patients with schizophrenia symptomatically maintained on risperidone. METHOD: Thirty patients taking risperidone were enrolled into the trial (CTRI/2012/11/003114). Aripiprazole was administered at a fixed daily dose of 10 mg/day for 8 weeks. Serum prolactin was measured at baseline and at 8 weeks. Hyperprolactinaemia-related problems, psychopathology and side-effects were evaluated every 2 weeks. RESULTS: Prolactin levels decreased by 58% in the aripiprazole group compared with an increase by 22% in the placebo group. Prolactin levels normalised in 46% of patients in the aripiprazole group (number needed to treat, NNT=2). Aripiprazole improved erectile dysfunction in five out of six patients. There were no significant differences in change in psychopathology or side-effects between groups. CONCLUSIONS: Adjunctive aripiprazole reduced prolactin levels in those treated with risperidone, with no effect on psychopathology and extrapyramidal symptoms. This is a potential treatment for hyperprolactinaemia observed during treatment with second-generation antipsychotics. DECLARATION OF INTEREST: None.

PMID- 27703747 TI - Origin and schizophrenia in young refugees and inter-country adoptees from Latin America and East Africa in Sweden: a comparative study. AB - BACKGROUND: Migrants' socioeconomic adversity has been linked to schizophrenia. AIMS: To investigate whether the more favourable socioeconomic situation of adoptees prevents them from the high risk of schizophrenia found in other migrants. METHOD: Register study in a cohort of refugees and inter-country adoptees aged 16-40 years, born in East Africa (n=8389), Latin America (n=11 572) and 1.2 million native Swedes. Cox-regression models estimated hazard ratios (HRs) of schizophrenia in data from psychiatric care. RESULTS: Despite diverse income levels, HRs for schizophrenia were similar for refugees and adoptees, with East Africans having the highest HRs: 5.83 (3.30-10.27) and 5.80 (5.03-6.70), followed by Latin Americans: HRs 3.09 (2.49-3.83) and 2.31 (1.79-2.97), compared with native Swedes. Adjustment for income decreased these risks slightly for refugees, but not for adoptees. CONCLUSIONS: This study suggests that risk factors associated with origin are more important determinants of schizophrenia than socioeconomic adversity in the country of settlement.

PMID- 27703748 TI - Hospital treatment, mortality and healthcare costs in relation to socioeconomic status among people with bipolar affective disorder. AB - BACKGROUND: Evidence regarding the relationships between the socioeconomic status and long-term outcomes of individuals with bipolar affective disorder (BPD) is lacking. AIMS: We aimed to estimate the effects of baseline socioeconomic status on longitudinal outcomes. METHOD: A national cohort of adult participants with newly diagnosed BPD was identified in 2008. The effects of personal and household socioeconomic status were explored on outcomes of hospital treatment, mortality and healthcare costs, over a 3-year follow-up period (2008-2011). RESULTS: A total of 7987 participants were recruited. The relative risks of hospital treatment and mortality were found elevated for the ones from low-income households who also had higher healthcare costs. Low premium levels did not correlate with future healthcare costs. CONCLUSIONS: Socioeconomic deprivation is associated with poorer outcome and higher healthcare costs in BPD patients. Special care should be given to those with lower socioeconomic status to improve outcomes with potential benefits of cost savings in the following years. DECLARATION OF INTEREST: None.

PMID- 27703749 TI - Claims for sickness and disability benefits owing to mental disorders in the UK: trends from 1995 to 2014. AB - BACKGROUND: There is international concern about the levels of sickness and disability benefits, with mental disorders known to account for a large proportion of claims. AIMS: To examine trends in sickness and disability benefits awarded for mental disorders in the UK. METHOD: The researchers analysed UK Government data from 1995 to 2014. RESULTS: Mental disorders have become the most common cause of receiving benefits, with the number of claimants rising by 103% from 1995 to 1.1 million in 2014. Claimants with other conditions fell by 35%. In 2014, 47% of claims were attributed to a mental disorder. The number of long-term claimants (claiming over 5 years) with mental disorders increased by 87% from 2000 to 2011. Two-thirds of mental disorder claimants were classified as having a depressive or anxiety disorder. CONCLUSIONS: Common mental disorders may involve greater morbidity and social costs than usually recognised. Availability of suitable employment, as well as individual support, may be necessary to reduce benefit levels. DECLARATION OF INTEREST: None.

PMID- 27703750 TI - The challenges of implementing ADHD clinical guidelines and research best evidence in routine clinical care settings: Delphi survey and mixed-methods study. AB - BACKGROUND: The landmark US Multimodal Treatment of ADHD (MTA) study established the benefits of individualised medication titration and optimisation strategies to improve short- to medium-term outcomes in attention-deficit hyperactivity disorder (ADHD). This individualised medication management approach was subsequently incorporated into the National Institute for Health and Care Excellence (NICE) ADHD Clinical Guidelines (NICE CG78). However, little is known about clinicians' attitudes towards implementing these medication management strategies for ADHD in routine care. AIMS: To examine National Health Service (NHS) healthcare professionals' consensus on ADHD medication management strategies. METHOD: Using the Delphi method, we examined perceptions on the importance and feasibility of implementing 103 ADHD treatment statements from sources including the UK NICE ADHD guidelines and US medication management algorithms. RESULTS: Certain recommendations for ADHD medication management were judged as important and feasible to implement, including a stepwise titration of stimulant medication. Other recommendations were perceived as important but not feasible to implement in routine practice, such as weekly clinic follow-up with the family during titration and collection of follow-up symptom questionnaires. CONCLUSIONS: Many of the key guideline recommendations for ADHD medication management are viewed by clinicians as important and feasible to implement. However, some recommendations present significant implementation challenges within the context of routine NHS clinical care in England.

PMID- 27703751 TI - The long-term mental health impact of peacekeeping: prevalence and predictors of psychiatric disorder. AB - BACKGROUND: The mental health outcomes of military personnel deployed on peacekeeping missions have been relatively neglected in the military mental health literature. AIMS: To assess the mental health impacts of peacekeeping deployments. METHOD: In total, 1025 Australian peacekeepers were assessed for current and lifetime psychiatric diagnoses, service history and exposure to potentially traumatic events (PTEs). A matched Australian community sample was used as a comparator. Univariate and regression analyses were conducted to explore predictors of psychiatric diagnosis. RESULTS: Peacekeepers had significantly higher 12-month prevalence of post-traumatic stress disorder (16.8%), major depressive episode (7%), generalised anxiety disorder (4.7%), alcohol misuse (12%), alcohol dependence (11.3%) and suicidal ideation (10.7%) when compared with the civilian comparator. The presence of these psychiatric disorders was most strongly and consistently associated with exposure to PTEs. CONCLUSIONS: Veteran peacekeepers had significant levels of psychiatric morbidity. Their needs, alongside those of combat veterans, should be recognised within military mental health initiatives. DECLARATION OF INTEREST: None.

PMID- 27703753 TI - The Problem Behaviour Checklist: short scale to assess challenging behaviours. AB - BACKGROUND: Challenging behaviour, especially in intellectual disability, covers a wide range that is in need of further evaluation. AIMS: To develop a short but comprehensive instrument for all aspects of challenging behaviour. METHOD: In the first part of a two-stage enquiry, a 28-item scale was constructed to examine the components of challenging behaviour. Following a simple factor analysis this was developed further to create a new short scale, the Problem Behaviour Checklist (PBCL). The scale was subsequently used in a randomised controlled trial and tested for interrater reliability. Scores were also compared with a standard scale, the Modified Overt Aggression Scale (MOAS). RESULTS: Seven identified factors - personal violence, violence against property, self-harm, sexually inappropriate, contrary, demanding and disappearing behaviour - were scored on a 5-point scale. A subsequent factor analysis with the second population showed demanding, violent and contrary behaviour to account for most of the variance. Interrater reliability using weighted kappa showed good agreement (0.91; 95% CI 0.83-0.99). Good agreement was also shown with scores on the MOAS and a score of 1 on the PBCL showed high sensitivity (97%) and specificity (85%) for a threshold MOASscore of 4. CONCLUSIONS: The PBCL appears to be a suitable and practical scale for assessing all aspects of challenging behaviour. DECLARATION OF INTEREST: None.

PMID- 27703752 TI - Low birth weight and features of neuroticism and mood disorder in 83 545 participants of the UK Biobank cohort. AB - BACKGROUND: Low birth weight has been inconsistently associated with risk of developing affective disorders, including major depressive disorder (MDD). To date, studies investigating possible associations between birth weight and bipolar disorder (BD), or personality traits known to predispose to affective disorders such as neuroticism, have not been conducted in large cohorts. AIMS: To assess whether very low birth weight (<1500 g) and low birth weight (1500-2490 g) were associated with higher neuroticism scores assessed in middle age, and lifetime history of either MDD or BD. We controlled for possible confounding factors. METHOD: Retrospective cohort study using baseline data on the 83 545 UK Biobank participants with detailed mental health and birth weight data. Main outcomes were prevalent MDD and BD, and neuroticism assessed using the Eysenck Personality Inventory Neuroticism scale - Revised (EPIN-R). RESULTS: Referent to normal birth weight, very low/low birth weight were associated with higher neuroticism scores, increased MDD and BD. The associations between birth weight category and MDD were partially mediated by higher neuroticism. CONCLUSIONS: These findings suggest that intrauterine programming may play a role in lifetime vulnerability to affective disorders. DECLARATION OF INTEREST: None.

AB - BACKGROUND: Symptoms of anxiety and depression are prevalent in older adults. AIMS: To compare clinician-guided and self-guided versions of a transdiagnostic internet-delivered cognitive-behavioural therapy (iCBT) intervention for adults aged 60 years and above. METHOD: Adults (n=433) with symptoms of anxiety and depression were randomly allocated to: (1) clinician-guided treatment (n=153); (2) initial clinician interview followed by self-guided treatment (n=140); or (3) self-guided treatment without interview (n=140). RESULTS: Large reductions (d >=1.00) in symptoms of depression and anxiety were observed across groups, and sustained at follow-up. No differences were observed in clinical outcomes or satisfaction ratings. Age did not affect outcomes. CONCLUSIONS: Carefully developed iCBT interventions may significantly reduce symptoms of anxiety and depression in older adults when delivered in either clinician-guided or self guided formats.

PMID- 27703755 TI - Long-term antipsychotic treatment in schizophrenia: systematic review and network meta-analysis of randomised controlled trials. AB - BACKGROUND: For treatment of patients diagnosed with schizophrenia, comparative long-term effectiveness of antipsychotic drugs to reduce relapses when minimising adverse effects is of clinical interest, hence prompting this review. AIMS: To evaluate the comparative long-term effectiveness of antipsychotic drugs. METHOD: We systematically searched electronic databases for reports of randomised controlled trials (RCTs) of antipsychotic monotherapy aimed at reducing relapse risks in schizophrenia. We conducted network meta-analysis of 18 antipsychotics and placebo. RESULTS: Studies of 10 177 patients in 56 reports were included; treatment duration averaged 48 weeks (range 4-156). Olanzapine was significantly more effective than chlorpromazine (odds ratio (OR) 0.35, 95% CI 0.14-0.88) or haloperidol (OR=0.50, 95% CI 0.30-0.82); and fluphenazine decanoate was more effective than chlorpromazine (OR=0.31, 95% CI 0.11-0.88) in relapse reduction. Fluphenazine decanoate, haloperidol, haloperidol decanoate and trifluoperazine produced more extrapyramidal adverse effects than olanzapine or quetiapine; and olanzapine was associated with more weight gain than other agents. CONCLUSIONS: Except for apparent superiority of olanzapine and fluphenazine decanoate over chlorpromazine, most agents showed intermediate efficacy for relapse prevention and differences among them were minor. Typical antipsychotics yielded adverse neurological effects, and olanzapine was associated with weight gain. The findings may contribute to evidence-based treatment selection for patients with chronic psychotic disorders. DECLARATION OF INTEREST: R.J.B. received grants from the Bruce J.

PMID- 27703756 TI - Online screening and feedback to increase help-seeking for mental health problems: population-based randomised controlled trial. AB - BACKGROUND: Community-based screening for mental health problems may increase service use through feedback to individuals about their severity of symptoms and provision of contacts for appropriate services. AIMS: The effect of symptom feedback on service use was assessed. Secondary outcomes included symptom change and study attrition. METHOD: Using online recruitment, 2773 participants completed a comprehensive survey including screening for depression (n=1366) or social anxiety (n=1407). Across these two versions, approximately half (n=1342) of the participants were then randomly allocated to receive tailored feedback. Participants were reassessed after 3 months (Australian New Zealand Clinical Trials Registry ANZCTR12614000324617). RESULTS: A negative effect of providing social anxiety feedback to individuals was observed, with significant reductions in professional service use. Greater attrition and lower intentions to seek help were also observed after feedback. CONCLUSIONS: Online mental health screening with feedback is not effective for promoting professional service use. Alternative models of online screening require further investigation.

PMID- 27703757 TI - Embodying self-compassion within virtual reality and its effects on patients with depression. AB - BACKGROUND: Self-criticism is a ubiquitous feature of psychopathology and can be combatted by increasing levels of self-compassion. However, some patients are resistant to self-compassion. AIMS: To investigate whether the effects of self identification with virtual bodies within immersive virtual reality could be exploited to increase self-compassion in patients with depression. METHOD: We developed an 8-minute scenario in which 15 patients practised delivering compassion in one virtual body and then experienced receiving it from themselves in another virtual body. RESULTS: In an open trial, three repetitions of this scenario led to significant reductions in depression severity and self-criticism, as well as to a significant increase in self-compassion, from baseline to 4-week follow-up. Four patients showed clinically significant improvement. CONCLUSIONS: The results indicate that interventions using immersive virtual reality may have considerable clinical potential and that further development of these methods preparatory to a controlled trial is now warranted.

PMID- 27703758 TI - Protocol investigating the clinical outcomes and cost-effectiveness of cognitive behavioural therapy delivered remotely for unscheduled care users with health anxiety: randomised controlled trial. AB - BACKGROUND: Health anxiety and medically unexplained symptoms cost the National Health Service (NHS) an estimated L3 billion per year in unnecessary costs with little evidence of patient benefit. Effective treatment is rarely taken up due to issues such as stigma or previous negative experiences with mental health services. An approach to overcome this might be to offer remotely delivered psychological therapy, which can be just as effective as face-to-face therapy and may be more accessible and suitable. AIMS: To investigate the clinical outcomes and cost-effectiveness of remotely delivered cognitive-behavioural therapy (CBT) to people with high health anxiety repeatedly accessing unscheduled care (trial registration: NCT02298036). METHOD: A multicentre randomised controlled trial (RCT) will be undertaken in primary and secondary care providers of unscheduled care across the East Midlands. One hundred and forty-four eligible participants will be equally randomised to receive either remote CBT (6-12 sessions) or treatment as usual (TAU). Two doctoral research studies will investigate the barriers and facilitators to delivering the intervention and the factors contributing to the optimisation of therapeutic outcome. RESULTS: This trial will be the first to test the clinical outcomes and cost-effectiveness of remotely delivered CBT for the treatment of high health anxiety. CONCLUSIONS: The findings will enable an understanding as to how this intervention might fit into a wider care pathway to enhance patient experience of care. DECLARATION OF INTEREST: None.

PMID- 27703759 TI - Auditory verbal hallucinations in first-episode psychosis: a phenomenological investigation. AB - BACKGROUND: In dimensional understanding of psychosis, auditory verbal hallucinations (AVH) are unitary phenomena present on a continuum from non clinical voice hearing to severe mental illness. There is mixed evidence for this approach and a relative absence of research into subjective experience of AVH in early psychosis. AIMS: To conduct primary research into the nature of subjective experience of AVH in first-episode psychosis. METHOD: A phenomenological study using diary and photo-elicitation qualitative techniques investigating the subjective experience of AVH in 25 young people with first-episode psychosis. RESULTS: AVH are characterised by: (a) entity, as though from a living being with complex social interchange; and (b) control, exerting authority with ability to influence. AVH are also received with passivity, often accompanied by sensation in other modalities. CONCLUSIONS: A modern detailed phenomenological investigation, without presupposition, gives results that echo known descriptive psychopathology. However, novel findings also emerge that may be features of AVH in psychosis not currently captured with standardised measures. DECLARATION OF INTEREST: None.

PMID- 27703760 TI - Predicting hospital aggression in secure psychiatric care. AB - BACKGROUND: Risk assessment instruments have become a preferred means for predicting future aggression, claiming to predict long-term aggression risk. AIMS: To investigate the predictive value over 12 months and 4 years of two commonly applied instruments (Historical, Clinical and Risk Management - 20 (HCR 20) and Violence Risk Appraisal Guide (VRAG)). METHOD: Participants were adult male psychiatric patients detained in a high secure hospital. All had a diagnosis of personality disorder. The focus was on aggression in hospital. RESULTS: The actuarial risk assessment (VRAG) was generally performing better than the structured risk assessment (HCR-20), although neither approach performed particularly well overall. Any value in their predictive potential appeared focused on the longer time period under study (4 years) and was specific to certain types of aggression. CONCLUSIONS: The value of these instruments for assessing aggression in hospital among patients with personality disorder in a high secure psychiatric setting is considered.

PMID- 27703761 TI - Is it time to abandon suicide risk assessment? AB - SUMMARY: Suicide risk assessment includes estimating the likelihood of suicide in words such as 'low, medium or high'. A 'high suicide risk' rating can trigger a powerful urge to eliminate risk immediately. But it is far from clear what 'high suicide risk' actually means. In the current state of knowledge, suicide reduction measures should apply to all psychiatric patients, irrespective of an individual patient's perceived risk. For patients presenting with suicidal thoughts, feelings and behaviour, assessment and management should focus on reducing or tolerating emotional pain.

PMID- 27703762 TI - Patient characteristics as a moderator of post-traumatic stress disorder treatment outcome: combining symptom burden and strengths. AB - BACKGROUND: Post-traumatic stress disorder (PTSD) psychotherapy research has failed to identify patient characteristics that consistently predict differential outcome. AIMS: To identify patient characteristics associated with differential outcome via a statistically generated composite moderator among women with childhood abuse-related PTSD in a randomised controlled trial comparing exposure therapy, skills training and their combination. METHOD: Six baseline patient characteristics were combined in a composite moderator of treatment effects for PTSD symptoms across the three treatment conditions through a 6-month follow-up. RESULTS: The optimal moderator was the combined burden of all symptoms and emotion regulation strength. Those with high moderator scores, reflecting high symptom load relative to emotion regulation, did least well in exposure, moderately well in skills and best in the combination. CONCLUSIONS: A clinically meaningful moderator, which combines patient symptom burden and strengths, was identified. Assessment at follow-up may provide a more accurate indicator of variability in outcome than that obtained immediately post-treatment. DECLARATION OF INTEREST: None.

AB - BACKGROUND: Estimates of the effectiveness of neurofeedback as a treatment for attention-deficit hyperactivity disorder (ADHD) are mixed. AIMS: To investigate the long-term additional effects of neurofeedback (NFB) compared with treatment as usual (TAU) for adolescents with ADHD. METHOD: Using a multicentre parallel randomised controlled trial design, 60 adolescents with a DSM-IV-TR diagnosis of ADHD receiving NFB+TAU (n=41) or TAU (n=19) were followed up. Neurofeedback treatment consisted of approximately 37 sessions of theta/sensorimotor rhythm (SMR)-training on the vertex (Cz). Outcome measures included behavioural self reports and neurocognitive measures. Allocation to the conditions was unmasked. RESULTS: At 1-year follow-up, inattention as reported by adolescents was decreased (range etap2=0.23-0.36, P<0.01) and performance on neurocognitive tasks was faster (range etap2=0.20-0.67, P<0.005) irrespective of treatment group. CONCLUSIONS: Overall, NFB+TAU was as effective as TAU. Given the absence of robust additional effects of neurofeedback in the current study, results do not support the use of theta/SMR neurofeedback as a treatment for adolescents with ADHD and comorbid disorders in clinical practice.

PMID- 27703764 TI - Light therapy for non-seasonal depression: systematic review and meta-analysis. AB - BACKGROUND: Light therapy is a known treatment for patients with seasonal affective disorder. However, the efficacy of light therapy in treating patients with non-seasonal depression remains inconclusive. AIMS: To provide the current state of evidence for efficacy of light therapy in non-seasonal depressive disorders. METHOD: Systematic review of randomised controlled trials (RCTs) was conducted by searching MEDLINE, EMBASE, PsycINFO, CINAHL, and CENTRAL from their inception to September 2015. Study selection, data abstraction and risk of bias assessment were independently conducted in duplicate. Meta-analyses were performed to provide a summary statistic for the included RCTs. The reporting of this systematic review follows the PRISMA guidelines. RESULTS: A meta-analysis including 881 participants from 20 RCTs demonstrated a beneficial effect of light therapy in non-seasonal depression (standardised mean difference in depression score -0.41 (95% CI -0.64 to -0.18)). This estimate was associated with significant heterogeneity (I2=60%, P=0.0003) that was not sufficiently explained by subgroup analyses. There was also high risk of bias in the included trials limiting the study interpretation. CONCLUSIONS: The overall quality of evidence is poor due to high risk of bias and inconsistency. However, considering that light therapy has minimal side-effects and our meta-analysis demonstrated that a significant proportion of patients achieved a clinically significant response, light therapy may be effective for patients with non-seasonal depression and can be a helpful additional therapeutic intervention for depression.

PMID- 27703765 TI - Case finding and screening clinical utility of the Patient Health Questionnaire (PHQ-9 and PHQ-2) for depression in primary care: a diagnostic meta-analysis of 40 studies. AB - BACKGROUND: The Patient Health Questionnaire (PHQ) is the most commonly used measure to screen for depression in primary care but there is still lack of clarity about its accuracy and optimal scoring method. AIMS: To determine via meta-analysis the diagnostic accuracy of the PHQ-9-linear, PHQ-9-algorithm and PHQ-2 questions to detect major depressive disorder (MDD) among adults. METHOD: We systematically searched major electronic databases from inception until June 2015. Articles were included that reported the accuracy of PHQ-9 or PHQ-2 questions for diagnosing MDD in primary care defined according to standard classification systems. We carried out a meta-analysis, meta-regression, moderator and sensitivity analysis. RESULTS: Overall, 26 publications reporting on 40 individual studies were included representing 26 902 people (median 502, s.d.=693.7) including 14 760 unique adults of whom 14.3% had MDD. The methodological quality of the included articles was acceptable. The meta-analytic area under the receiver operating characteristic curve of the PHQ-9-linear and the PHQ-2 was significantly higher than the PHQ-9-algorithm, a difference that was maintained in head-to-head meta-analysis of studies. Our best estimates of sensitivity and specificity were 81.3% (95% CI 71.6-89.3) and 85.3% (95% CI 81.0 89.1), 56.8% (95% CI 41.2-71.8) and 93.3% (95% CI 87.5-97.3) and 89.3% (95% CI 81.5-95.1) and 75.9% (95% CI 70.1-81.3) for the PHQ-9-linear, PHQ-9-algorithm and PHQ-2 respectively. For case finding (ruling in a diagnosis), none of the methods were suitable but for screening (ruling out non-cases), all methods were encouraging with good clinical utility, although the cut-off threshold must be carefully chosen. CONCLUSIONS: The PHQ can be used as an initial first step assessment in primary care and the PHQ-2 is adequate for this purpose with good acceptability. However, neither the PHQ-2 nor the PHQ-9 can be used to confirm a clinical diagnosis (case finding). DECLARATION OF INTEREST: None. COPYRIGHT AND USAGE: (c) The Royal College of Psychiatrists 2016.

PMID- 27703766 TI - The effect of second-generation antipsychotics on hippocampal volume in first episode of psychosis: longitudinal study. AB - BACKGROUND: Current neuroscience literature has related treatment with aripiprazole to improved memory performance and subcellular changes in the hippocampus. AIMS: To explore the volumetric changes in hippocampal grey matter in people with a first episode of psychosis (FEP) treated with second-generation antipsychotics. METHOD: Baseline and 1-year follow-up magnetic resonance images were obtained. Hippocampal volumes were estimated by using FreeSurfer and MAGeT Brain. Subgroups included: aripiprazole (n=13), olanzapine (n=12), risperidone/paliperidone (n=24), refused-antipsychotics (n=13) and controls (n=44). RESULTS: Aripiprazole subgroup displayed significant increases in bilateral hippocampal volume compared with all other subgroups (FreeSurfer: all P's<0.012; MAGeT-Brain: all P's<0.040). CONCLUSIONS: Aripiprazole is a first line, second-generation treatment option that may provide an added benefit of pro hippocampal growth. The biological underpinnings of these changes should be the focus of future investigations and may be key towards achieving a better clinical outcome for more individuals.

PMID- 27703767 TI - Mental capacity to consent to treatment in anorexia nervosa: explorative study. AB - BACKGROUND: Mental capacity to consent to treatment in anorexia nervosa is a neglected area in clinical decision-making. AIMS: To examine clinical and neuropsychological parameters associated with diminished mental capacity in anorexia nervosa. METHOD: An explorative study was conducted in 70 adult female patients with severe anorexia nervosa. Mental capacity to consent to treatment was assessed by experienced psychiatrists. Further measurements included the MacCAT-T (to assess mental capacity status), a range of clinical measures (body mass index (BMI) and comorbidity) and neuropsychological tests assessing decision making, central coherence and set-shifting capacity. RESULTS: Diminished mental capacity occurs in a third of patients with severe anorexia nervosa and is associated with a low BMI, less appreciation of illness and treatment, previous treatment for anorexia nervosa, low social functioning and poor set shifting. CONCLUSIONS: Assessment of diminished mental capacity in anorexia nervosa requires careful evaluation of not only BMI, but also the degree of appreciation of illness and treatment, history and the tendency to have a rigid thinking style.

AB - BACKGROUND: Internet cognitive-behavioural therapy (iCBT) for panic disorder of up to 10 lessons is well established. The utility of briefer programmes is unknown. AIMS: To determine the efficacy and effectiveness of a five-lesson iCBT programme for panic disorder. METHOD: Study 1 (efficacy): Randomised controlled trial comparing active iCBT (n=27) and waiting list control participants (n=36) on measures of panic severity and comorbid symptoms. Study 2 (effectiveness): 330 primary care patients completed the iCBT programme under the supervision of primary care practitioners. RESULTS: iCBT was significantly more effective than waiting list control in reducing panic (g=0.97, 95% CI 0.34 to 1.61), distress (g=0.92, 95% CI 0.28 to 1.55), disability (g=0.81, 95% CI 0.19 to 1.44) and depression (g=0.79, 95% CI 0.17 to 1.41), and gains were maintained at 3 months post-treatment (iCBT group). iCBT remained effective in primary care, but lower completion rates were found (56.1% in study 2 v. 63% in study 1). Adherence appeared to be related to therapist contact. CONCLUSIONS: The five-lesson Panic Program has utility for treating panic disorder, which translates to primary care. Adherence may be enhanced with therapist contact. DECLARATION OF INTEREST: None. COPYRIGHT AND USAGE: (c) The Royal College of Psychiatrists 2016.

PMID- 27703769 TI - Testing the social competition hypothesis of depression using a simple economic game. AB - BACKGROUND: Price's social competition hypothesis interprets the depressive state as an unconscious, involuntary losing strategy, which enables individuals to yield and accept defeat in competitive situations. AIMS: We investigated whether patients who suffer from major depressive disorder (MDD) would avoid competition more often than either patients suffering from borderline personality disorder (BPD) or healthy controls. METHOD: In a simple paper-folding task healthy participants and patiens with MDD and BPD were matched with two opponents, one with an unknown diagnosis and one who shared their clinical diagnosis, and they had to choose either a competitive or cooperative payment scheme for task completion. RESULTS: When playing against an unknown opponent, but not the opponent with the same diagnosis, the patients with depression chose the competitive payment scheme statistically less often than healthy controls and patients diagnosed with BPD. CONCLUSION: The competition avoidance against the unknown opponent is consistent with Price's social competition hypothesis.

PMID- 27703770 TI - Maternal vitamin D deficiency and the risk of autism spectrum disorders: population-based study. AB - BACKGROUND: Maternal vitamin D deficiency may increase risk of autism spectrum disorder (ASD), but direct evidence is lacking. AIMS: To clarify the relationship between maternal vitamin D deficiency and offspring risk of ASD with and without intellectual disability. METHOD: Using a register-based total population study (N=509 639), we calculated adjusted odds ratios (aORs) and 95% confidence intervals (CIs) of ASD with and without intellectual disability in relation to lifetime diagnoses of maternal vitamin D deficiency. Although rare, such deficiency was associated with offspring risk of ASD with, but not without, intellectual disability (aORs 2.51, 95% CI 1.22-5.16 and 1.28, 0.68-2.42). Relationships were stronger in non-immigrant children. CONCLUSIONS: If reflecting associations for prenatal hypovitaminosis, these findings imply gestational vitamin D substitution as a means of ASD prevention. DECLARATION OF INTEREST: None.

PMID- 27703771 TI - The use of social environment in a psychosocial clubhouse to facilitate recovery oriented practice. AB - BACKGROUND: Recovery-oriented language has been widely adopted in mental health policy; however, little is known about how recovery practices are implemented within individual services, such as psychosocial clubhouses. AIMS: To explore how recovery practices are implemented in a psychosocial clubhouse. METHOD: Qualitative case study design informed by self-determination theory was utilised. This included 120 h of participant observation, interviews with 12 clubhouse members and 6 staff members. Field notes and interview transcripts were subject to theoretical thematic analysis. RESULTS: Two overarching themes were identified, each comprising three sub-themes. In this paper, the overarching theme of 'social environment' is discussed. It was characterised by the sub themes, 'community and consistency', 'participation and opportunity' and 'respect and autonomy'. CONCLUSIONS: Social environment was used to facilitate recovery oriented practice within the clubhouse. Whether recovery is experienced by clubhouse members in wider society, may well depend on supports and opportunities outside the clubhouse. DECLARATION OF INTERESTS: None.

AB - BACKGROUND: While up to 45% of individuals with intellectual and developmental disabilities (IDD) have a comorbid psychiatric disorder, and antipsychotics are commonly prescribed, gender differences in the safety of antipsychotics have rarely been studied in this population. AIMS: To compare men and women with IDD on medical outcomes after antipsychotic initiation. METHOD: Our population-based study in Ontario, Canada, compared 1457 women and 1951 men with IDD newly initiating antipsychotic medication on risk for diabetes mellitus, hypertension, venous thromboembolism, myocardial infarction, stroke and death, with up to 4 years of follow-up. RESULTS: Women were older and more medically complex at baseline. Women had higher risks for venous thromboembolism (HR 1.72, 95% CI 1.15 2.59) and death (HR 1.46, 95% CI 1.02-2.10) in crude analyses; but only thromboembolism risk was greater for women after covariate adjustment (aHR 1.58, 95% CI 1.05-2.38). CONCLUSIONS: Gender should be considered in decision-making around antipsychotic medications for individuals with IDD. DECLARATION OF INTEREST: None.

PMID- 27703772 TI - The People with Asperger syndrome and anxiety disorders (PAsSA) trial: a pilot multicentre, single-blind randomised trial of group cognitive-behavioural therapy. AB - BACKGROUND: There is a growing interest in using cognitive-behavioural therapy (CBT) with people who have Asperger syndrome and comorbid mental health problems. AIMS: To examine whether modified group CBT for clinically significant anxiety in an Asperger syndrome population is feasible and likely to be efficacious. METHOD: Using a randomised assessor-blind trial, 52 individuals with Asperger syndrome were randomised into a treatment arm or a waiting-list control arm. After 24 weeks, those in the waiting-list control arm received treatment, while those initially randomised to treatment were followed up for 24 weeks. RESULTS: The conversion rate for this trial was high (1.6:1), while attrition was 13%. After 24 weeks, there was no significant difference between those randomised to the treatment arm compared with those randomised to the waiting-list control arm on the primary outcome measure, the Hamilton Rating Scale for Anxiety. CONCLUSIONS: Trials of psychological therapies with this population are feasible. Larger definitive trials are now needed. DECLARATION OF INTEREST: None.

AB - : Late-life depression affects 2-6% of seniors aged 60 years and above. Patients are increasingly embracing non-pharmacological therapies, many of which have not been scientifically evaluated. This study aimed to evaluate a category of meditation, automatic self-transcending meditation (ASTM), in alleviating symptoms of depression when augmenting treatment as usual (NCT02149810). The preliminary results of an ongoing single-blind randomised controlled trial comparing a training programme involving ASTM with a wait-list control indicate that a 12-week ASTM programme may lead to significantly greater reductions in depression and anxiety severity. As such, ASTM may be an effective adjunctive therapy in the treatment of late-life depression.

AIMS: This paper reports the usage data of the first trial of Catch It, a new CBT smartphone app. METHOD: Uptake and usage rates, fidelity of user responses to CBT principles, and impact on reported negative and positive moods were assessed. RESULTS: A relatively modest proportion of people chose to download the app. Once used, the app tended to be used more than once, and 84% of the user-generated content was consistent with the basic concepts of CBT. There were statistically significant reductions in negative mood intensity and increases in positive mood intensity. CONCLUSIONS: Smartphone apps have potential beneficial effects in mental health through the application of basic CBT principles. More research with randomised controlled trial designs should be conducted. DECLARATION OF INTEREST: None. COPYRIGHT AND USAGE: (c) The Royal College of Psychiatrists 2016.

PMID- 27703776 TI - A cross-sectional study of problem gambling and its correlates among college students in South India. AB - BACKGROUND: In the Western world, a significant portion of college students have gambled. College gamblers have one of the highest rates of problem gambling. To date, there have been no studies on gambling participation or the rates of problem gambling in India. AIMS: This study evaluated the prevalence of gambling participation and problem gambling in college students in India. It also evaluated demographic and psychosocial correlates of gambling in that population. METHOD: We surveyed 5784 college students from 58 colleges in the district of Ernakulam, Kerala, India, using cluster random sampling. Students completed questionnaires that addressed gambling, substance use, psychological distress, suicidality and attention-deficit hyperactivity disorder (ADHD). RESULTS: A total of 5580 completed questionnaires were returned, and while only 1090 (19.5%) college students reported having ever gambled, 415 (7.4%) reported problem gambling. Lotteries were the most popular form of gambling. Problem gamblers in comparison with non-gamblers were significantly more likely to be male, have a part-time job, greater academic failures, higher substance use, higher psychological distress scores, higher suicidality and higher ADHD symptom scores. In comparison with non-problem gamblers, problem gamblers were significantly more likely to have greater academic failures, higher psychological distress scores, higher suicidality and higher ADHD symptom scores. CONCLUSIONS: This study, the first to look at the prevalence of gambling in India, found relatively low rates of gambling participation in college students but high rates of problem gambling among those who did gamble. Correlates of gambling were generally similar to those noted in other countries. Since 38% of college students who had gambled had a gambling problem, there is a need for immediate public health measures to raise awareness about gambling, and to prevent and treat problem gambling in this population.

PMID- 27703779 TI - 'He left me a message on Facebook': comparing the risk profiles of self-harming patients who leave paper suicide notes with those who leave messages on new media. AB - BACKGROUND: In cases of non-fatal self-harm, suicide notes are a major risk factor for repeated self-harm and suicide. Suicide notes can now be left on new media services, emails or text messages, as well as on paper. AIMS: In a group of people who had harmed themselves, we aimed to compare new media note-leavers with paper note-leavers and characterise these groups demographically and by risk factors. METHOD: Clinical notes of patients who presented with non-fatal self harm to two London emergency departments were anonymously searched for mentions of new media use. These were categorised and risk factors were compared for those who had left a new media note, a paper note, or no note to establish differences in risk of note-leaving. RESULTS: New media note-leaving was associated with younger age and substance use; both risk factors for repeated self-harm. However, suicidal intent remained highest in paper note-leavers. CONCLUSIONS: Paper note leavers remain at greatest risk, however new media note leaving is still correlated with risk factors related to repeated self-harm and suicide. Clinicians should enquire about new media use during emergency department assessments of self-harm. DECLARATION OF INTEREST: None. COPYRIGHT AND USAGE: (c) The Royal College of Psychiatrists 2016.

PMID- 27703778 TI - Asperger syndrome in childhood - personality dimensions in adult life: temperament, character and outcome trajectories. AB - BACKGROUND: Temperament and character have been shown to be important factors in understanding psychiatric and neurodevelopmental disorder. Adults with autism spectrum disorder (ASD) have repeatedly been shown to have a distinct temperament and character, but this has not been evaluated in relation to psychiatric comorbidity and ASD diagnostic stability. AIMS: To examine temperament and character in males that were diagnosed with ASD in childhood and followed prospectively over almost two decades. METHOD: Temperament and character were assessed in 40 adult males with a childhood diagnosis of ASD. Results were analysed by the stability of ASD diagnosis over time and current psychiatric comorbidity. RESULTS: Three distinct temperament and character profiles emerged from the data. Those no longer meeting criteria for ASD had high reward dependence while those with a stable ASD diagnosis and psychiatric comorbidity showed elevated harm avoidance and low self-directedness and cooperativeness. Finally, those with a stable ASD and no comorbidity showed low novelty seeking and somewhat elevated harm avoidance. CONCLUSIONS: Temperament and character are important factors correlated with long-term diagnostic stability and psychiatric comorbidity in males diagnosed with ASD in childhood.

PMID- 27703780 TI - Mental disorders in new parents before and after birth: a population-based cohort study. AB - BACKGROUND: Mental disorders of women during the postnatal period are a major public health problem. Compared with women's mental disorders, much less attention has been paid to men's mental disorders in the perinatal period. To date, there have been no reports in the literature describing secular changes of both maternal and paternal hospital admissions for mental disorders over the period covering the year before pregnancy (non-parents), during pregnancy (expectant parents) and up to the first year after birth (parents) based on linked parental data. The co-occurrences of couples' hospital admissions for mental disorders have not previously been investigated. AIMS: To describe maternal and paternal hospital admissions for mental disorders before and after birth. To compare the co-occurrences of parents' hospital admissions for mental disorder in the perinatal period. METHOD: This is a cohort study using paired parents' population data from the New South Wales (NSW) Perinatal Data Collection (PDC), Registry of Births, Deaths and Marriages (RBDM) and Admitted Patients Data Collection (APDC). The study included all parents (n=196 669 couples) who gave birth to their first child in NSW between 1 January 2003 and 31 December 2009. RESULTS: The hospital admission rate for women with a principal mental disorder diagnosis in the period between the year before pregnancy and the first year after birth was significantly higher than that for men. Parents' mental disorders influenced each other. If a man was admitted to hospital with a principal mental disorder diagnosis, his wife or partner was more likely to be admitted to hospital with a principal mental disorder diagnosis compared with women whose partner had not had a hospital admission, and vice versa. CONCLUSIONS: Mothers' mental disorders after birth increased more significantly than fathers. However, fathers' mental disorders significantly impacted the co-occurrence of mothers' mental disorders.

PMID- 27703781 TI - Inflammatory response to clozapine in the absence of myocarditis: case report. AB - SUMMARY: A case is presented of a 25-year-old man with treatment-resistant paranoid schizophrenia whose only previous trial of clozapine had been stopped following a suspected clozapine-induced myocarditis. Due to the failure of his psychosis to respond to a number of antipsychotic treatments and augmentation strategies, clozapine was restarted on admission. His rechallenge was marked by intermittent pyrexia, tachycardia and elevated C-reactive protein (CRP), but eosinophilia was absent. Clozapine was started and then stopped twice following extensive investigation and with specialist cardiology consultation. Physical symptoms and CRP elevation resolved shortly after clozapine cessation. We believe this constituted an idiosyncratic systemic inflammatory response to clozapine treatment.

PMID- 27703782 TI - Ketamine: stimulating antidepressant treatment? AB - SUMMARY: The appeal of ketamine - in promptly ameliorating depressive symptoms even in those with non-response - has led to a dramatic increase in its off-label use. Initial promising results await robust corroboration and key questions remain, particularly concerning its long-term administration. It is, therefore, timely to review the opinions of mood disorder experts worldwide pertaining to ketamine's potential as an option for treating depression and provide a synthesis of perspectives - derived from evidence and clinical experience - and to consider strategies for future investigations.

PMID- 27703783 TI - Diagnostic potential of structural neuroimaging for depression from a multi ethnic community sample. AB - BACKGROUND: At present, we do not have any biological tests which can contribute towards a diagnosis of depression. Neuroimaging measures have shown some potential as biomarkers for diagnosis. However, participants have generally been from the same ethnic background while the applicability of a biomarker would require replication in individuals of diverse ethnicities. AIMS: We sought to examine the diagnostic potential of the structural neuroanatomy of depression in a sample of a wide ethnic diversity. METHOD: Structural magnetic resonance imaging (MRI) scans were obtained from 23 patients with major depressive disorder in an acute depressive episode (mean age: 39.8 years) and 20 matched healthy volunteers (mean age: 38.8 years). Participants were of Asian, African and Caucasian ethnicity recruited from the general community. RESULTS: Structural neuroanatomy combining white and grey matter distinguished patients from controls at the highest accuracy of 81% with the most stable pattern being at around 70%. A widespread network encompassing frontal, parietal, occipital and cerebellar regions contributed towards diagnostic classification. CONCLUSIONS: These findings provide an important step in the development of potential neuroimaging based tools for diagnosis as they demonstrate that the identification of depression is feasible within a multi-ethnic group from the community.

PMID- 27703784 TI - Increased anticipatory but decreased consummatory brain responses to food in sisters of anorexia nervosa patients. AB - BACKGROUND: We have previously shown increased anticipatory and consummatory neural responses to rewarding and aversive food stimuli in women recovered from anorexia nervosa (AN). AIMS: To determine whether these differences are trait markers for AN, we examined the neural response in those with a familial history but no personal history of AN. METHOD: Thirty-six volunteers were recruited: 15 who had a sister with anorexia nervosa (family history) and 21 control participants. Using fMRI we examined the neural response during an anticipatory phase (food cues, rewarding and aversive), an effort phase and a consummatory phase (rewarding and aversive tastes). RESULTS: Family history (FH) volunteers showed increased activity in the caudate during the anticipation of both reward and aversive food and in the thalamus and amygdala during anticipation of aversive only. FH had decreased activity in the dorsal anterior cingulate cortex, the pallidum and the superior frontal gyrus during taste consumption. CONCLUSIONS: Increased neural anticipatory but decreased consummatory responses to food might be a biomarker for AN. Interventions that could normalise these differences may help to prevent disorder onset.

PMID- 27703785 TI - Cost-effectiveness of telehealth for patients with depression: evidence from the Healthlines randomised controlled trial. AB - BACKGROUND: Depression is a prevalent long-term condition that is associated with substantial resource use. Telehealth may offer a cost-effective means of supporting the management of people with depression. AIMS: To investigate the cost-effectiveness of a telehealth intervention ('Healthlines') for patients with depression. METHOD: A prospective patient-level economic evaluation conducted alongside a randomised controlled trial. Patients were recruited through primary care, and the intervention was delivered via a telehealth service. Participants with a confirmed diagnosis of depression and PHQ-9 score >=10 were recruited from 43 English general practices. A series of up to 10 scripted, theory-led, telephone encounters with health information advisers supported participants to effect a behaviour change, use online resources, optimise medication and improve adherence. The intervention was delivered alongside usual care and was designed to support rather than duplicate primary care. Cost-effectiveness from a combined health and social care perspective was measured by net monetary benefit at the end of 12 months of follow-up, calculated from incremental cost and incremental quality-adjusted life years (QALYs). Cost-consequence analysis included cost of lost productivity, participant out-of-pocket expenditure and the clinical outcome. RESULTS: A total of 609 participants were randomised - 307 to receive the Healthlines intervention plus usual care and 302 to receive usual care alone. Forty-five per cent of participants had missing quality of life data, 41% had missing cost data and 51% of participants had missing data on either cost or utility, or both. Multiple imputation was used for the base-case analysis. The intervention was associated with incremental mean per-patient National Health Service/personal social services cost of L168 (95% CI L43 to L294) and an incremental QALY gain of 0.001 (95% CI -0.023 to 0.026). The incremental cost effectiveness ratio was L132 630. Net monetary benefit at a cost-effectiveness threshold of L20 000 was -L143 (95% CI -L164 to -L122) and the probability of the intervention being cost-effective at this threshold value was 0.30. Productivity costs were higher in the intervention arm, but out-of-pocket expenses were lower. CONCLUSIONS: The Healthlines service was acceptable to patients as a means of condition management, and response to treatment after 4 months was higher for participants randomised to the intervention. However, the positive average intervention effect size was modest, and incremental costs were high relative to a small incremental QALY gain at 12 months. The intervention is not likely to be cost-effective in its current form. DECLARATION OF INTEREST: None. COPYRIGHT AND USAGE: (c) The Royal College of Psychiatrists 2016.

AB - SUMMARY: Epilepsy is one of the most serious neurological conditions and has an impact not only on the affected individual but also on the family and, indirectly, on the community. A global approach to the individual must take into account cognitive problems, psychiatric comorbidities and all psychosocial complications that often accompany epilepsy. We discuss psychosocial issues in epilepsy with special focus on the relationship between stigma and psychiatric comorbidities. Social barriers to optimal care and health outcomes for people with epilepsy result in huge disparities, and the public health system needs to invest in awareness programmes to increase public knowledge and reduce stigma in order to minimise such disparities.

PMID- 27703787 TI - The association between borderline personality disorder, fibromyalgia and chronic fatigue syndrome: systematic review. AB - BACKGROUND: Overlap of aetiological factors and demographic characteristics with clinical observations of comorbidity has been documented in fibromyalgia syndrome, chronic fatigue syndrome (CFS) and borderline personality disorder (BPD). AIMS: The purpose of this study was to assess the association of BPD with fibromyalgia syndrome and CFS. The authors reviewed literature on the prevalence of BPD in patients with fibromyalgia or CFS and vice versa. METHODS: A search of five databases yielded six eligible studies. A hand search and contact with experts yielded two additional studies. We extracted information pertaining to study setting and design, demographic information, diagnostic criteria and prevalence. RESULTS: We did not identify any studies that specifically assessed the prevalence of fibromyalgia or CFS in patients with BPD. Three studies assessed the prevalence of BPD in fibromyalgia patients and reported prevalence of 1.0, 5.25 and 16.7%. Five studies assessed BPD in CFS patients and reported prevalence of 3.03, 1.8, 2.0, 6.5 and 17%. CONCLUSIONS: More research is required to clarify possible associations between BPD, fibromyalgia and CFS. DECLARATION OF INTEREST: None.

AB - BACKGROUND: Attention-deficit hyperactivity disorder (ADHD) shows clear, albeit heterogeneous, cognitive dysfunctions. However, personality traits are not well understood in adults with ADHD, and it is unclear whether they are predisposing factors or phenotypical facets of the condition. AIMS: To assess whether personality traits of impulsivity, sensation seeking and sensitivity to punishment and reward are predisposing factors for ADHD or aspects of the clinical phenotype. METHOD: Twenty adults with ADHD, 20 unaffected first-degree relatives and 20 controls completed rating scales assessing traits of impulsivity, sensation seeking and sensitivity to punishment/reward. RESULTS: Compared with relatives and controls, individuals with ADHD showed increased impulsive personality traits, were more susceptible to boredom and presented hypersensitivity to reward but normal sensitivity to punishment. CONCLUSIONS: High impulsivity traits, heightened sensitivity to reward and boredom are associated with the phenotype of ADHD, rather than being predisposing factors, as these traits were not shared between ADHD probands and their relatives.

PMID- 27703791 TI - Initiation of pharmacotherapy for post-traumatic stress disorder among veterans from Iraq and Afghanistan: a dimensional, symptom cluster approach. AB - BACKGROUND: The pharmacological treatment of post-traumatic stress disorder (PTSD) is extremely challenging, as no specific agent has been developed exclusively to treat this disorder. Thus, there are growing concerns among the public, providers and consumers associated with its use as the efficacy of some agents is still in question. AIMS: We applied a dimensional and symptom cluster based approach to better understand how the heterogeneous phenotypic presentation of PTSD may relate to the initiation of pharmacotherapy for PTSD initial episode. METHOD: US veterans who served in the conflicts in Iraq and Afghanistan and received an initial PTSD diagnosis at the US Veterans Health Administration between 2008 and 2011 were included in this study. Veterans were followed for 365 days from initial PTSD diagnosis to identify initiation for antidepressants, anxiolytics/sedatives/hypnotics, antipsychotics and prazosin. Multivariable analyses were used to assess the relationship between the severity of unique PTSD symptom clusters and receiving prescriptions from each medication class, as well as the time from diagnosis to first prescription. RESULTS: Increased severity of emotional numbing symptoms was independently associated with the prescription of antidepressants, and they were prescribed after a substantially shorter period of time than other medications. Anxiolytics/sedatives/hypnotics prescription was associated with heightened re-experiencing symptoms and sleep difficulties. Antipsychotics were associated with elevated re-experiencing and numbing symptoms and prazosin with reported nightmares. CONCLUSIONS: Prescribing practices for military-related PTSD appear to follow US VA/DoD clinical guidelines. Results of this study suggest that a novel dimensional and symptom cluster-based approach to classifying the phenotypic presentation of military-related PTSD symptoms may help inform prescribing patterns for PTSD.

PMID- 27703792 TI - Women with bipolar disorder and pregnancy: factors influencing their decision making. AB - BACKGROUND: Women with bipolar disorder are at increased risk of having a severe episode of illness associated with childbirth. AIMS: To explore the factors that influence the decision-making of women with bipolar disorder regarding pregnancy and childbirth. METHOD: Qualitative study with a purposive sample of women with bipolar disorder considering pregnancy, or currently or previously pregnant, supplemented by data from an online forum. Data were analysed using thematic analysis. RESULTS: Twenty-one women with bipolar disorder from an NHS organisation were interviewed, and data were used from 50 women's comments via the online forum of the UK's national bipolar charity. The centrality of motherhood, social and economic contextual factors, stigma and fear were major themes. Within these themes, new findings included women considering an elective Caesarian section in an attempt to avoid the deleterious effects of a long labour and loss of sleep, or trying to avoid the risks of pregnancy altogether by means of adoption or surrogacy. CONCLUSIONS: This study highlights the information needs of women with bipolar disorder, both pre-conception and when childbearing, and the need for improved training for all health professionals working with women with bipolar disorder of childbearing age to reduce stigmatising attitudes and increase knowledge of the evidence base on treatment in the perinatal period.

PMID- 27703793 TI - GADL1 variant and medication adherence in predicting response to lithium maintenance treatment in bipolar I disorder. AB - BACKGROUND: Genetic variants and medication adherence have been identified to be the main factors contributing to lithium treatment response in bipolar disorders. AIMS: To simultaneously examine effects of variant glutamate decarboxylase-like protein 1 (GADL1) and medication adherence on response to lithium maintenance treatment in Han Chinese patients with bipolar I (BPI) disorder. METHOD: Frequencies of manic and depressive episodes between carriers and non-carriers of the effective GADL1 rs17026688 T allele during the cumulative periods of off lithium, poor adherence to lithium treatment and good adherence to lithium treatment were compared in Han Chinese patients with BPI disorder (n=215). RESULTS: GADL1 rs17026688 T carriers had significantly lower frequencies of recurrent affective episodes than non-T carriers during the cumulative period of good adherence, but not during those of poor adherence. CONCLUSIONS: GADL1 rs17026688 and medication adherence jointly predict response to lithium maintenance treatment in Han Chinese BPI patients. DECLARATION OF INTEREST: None.

PMID- 27703794 TI - Internet-delivered treatment for older adults with anxiety and depression: implementation of the Wellbeing Plus Course in routine clinical care and comparison with research trial outcomes. AB - BACKGROUND: The Wellbeing Plus Course is an internet-delivered psychological intervention for older adults with anxiety or depression. AIMS: To compare the effectiveness of the Wellbeing Plus Course in a public health setting (clinic group) with its efficacy in a randomised controlled trial (research group). METHOD: Participants (n=949) were Australian adults aged 60 and above. Primary outcome measures were the Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder scale (GAD-7). RESULTS: Initial symptom severity was higher in the clinic group and course completion was lower. Both groups showed significant symptom reductions at post-treatment and were satisfied with the treatment. Results were maintained at 3-month follow-up. Within-group symptom changes were comparable between settings; there were no between-group differences on primary outcomes or satisfaction. CONCLUSIONS: The Wellbeing Plus Course is as effective and acceptable in routine clinical care, as it is in controlled research trials. DECLARATION OF INTEREST: N.T. and B.F.D developed the Wellbeing Plus Course but derived no financial benefit from it. COPYRIGHT AND USAGE: (c) The Royal College of Psychiatrists 2016.

PMID- 27703795 TI - Heart Attack in the Course of Lithium Overdose. AB - INTRODUCTION: Lithium overdose can be associated with cardiac toxicity, especially in those with underlying heart disease. Toxic levels of serum lithium are associated with cardiotoxic effects ranging from simple ECG disorders to dysrhythmias, cardiomyopathy and even acute myocardial infarction (AMI). This report describes a patient with AMI accompanied by high blood levels of lithium. CASE PRESENTATION: A 62-year-old woman was admitted to the emergency department due to weakness and acute chest pain. Her ECG revealed ST elevation in leads DI, aVL and V5-6, with a ventricular rate of 80 bpm. Blood chemistry and complete blood count were within normal limits. The patient's blood lithium level was measured as 2.3 mmol/L (N: 0.5 - 0.8 mmol/L), and her troponin I level was 0.892 ng/mL (N: 0 - 0.01 ng/mL). Coronary angiography produced normal findings, concurrent with the resolution of electrocardiographic abnormalities following elimination of lithium. The clinical course in the intensive care unit was uneventful and the patient was discharged on the seventh day. CONCLUSIONS: Lithium intoxication should be considered in the differential diagnosis, especially in elderly patients on lithium therapy who are admitted to the emergency department with chest pain. PMID- 27703796 TI - Comparing the Excessive Daytime Sleepiness of Obese and Non-obese Patients. AB - BACKGROUND: Obesity, particularly morbid obesity, has various physical and mental complications. Excessive daytime somnolence (EDS) is a sleep disorder that reduces individuals' performance capability and the accuracy of their short-term memory and causes learning problems. This retrospective study aimed to document the presence of EDS in a sample of obese patients in comparison to patients with a normal weight. OBJECTIVES: This article compares the excessive daytime sleepiness of obese and non-obese patients in the minimally invasive surgery research center in Tehran, Iran. PATIENTS AND METHODS: In this case-control study, we compared excessive daytime sleepiness in 55 obese patients who were candidates for laparoscopic surgery, with a body mass index (BMI) of equal to or greater than 30 kg/ m2, with 55 controls with a normal BMI (19.5 - 24.9 kg/ m2). The process of selecting the control group in our case-control study is matching in group levels, so that the controls are similar to the case group with regard to certain key characteristics, such as age, sex, and race. The sleep assessment was based on the Epworth sleepiness scale (ESS) questionnaire. Analysis of variance (ANOVA) was used to compare the means of quantitative data, such as the ESS score of groups. RESULTS: Sleepiness was not affected by gender in cases or controls. The sleepiness prevalence was 29 (52.7%) in the cases group and 17 (30.9%) in the control group (OR = 2.493 (95% CI 1.144 -5.435)). The mean ESS scores in cases and controls were 7.82 +/- 3.86 and 10.54 +/- 6.15, respectively (P = 0.007). Moreover, the prevalence of sleepiness and the mean ESS scores in class III of obesity differed significantly from the controls (16 (57.1%) vs. 17 (30.9%)) (OR = 2.980 (95% CI 1.162 - 7.645)) and (11.04 +/- 5.93 vs. 7.82 +/- 3.86) (P = 0.013), respectively. CONCLUSIONS: Our findings suggest a strong relationship between EDS and obesity, particularly morbid obesity. Therefore, physicians must be familiar with EDS as a mixed clinical entity indicating careful assessment and specific treatment planning. PMID- 27703797 TI - Participation a Key Factor for Life Recovery After Disaster: A Grounded Theory Study in an Iranian Context. AB - BACKGROUND: Since life recovery after disasters is a subjective and multifaceted construct influenced by different factors, and survivors' main concerns and experiences are not clear, the researchers intended to explore this process. MATERIALS AND METHODS: This study was conducted in 2011 - 2014 based on the grounded theory approach. Participants were selected by purposeful sampling followed by theoretical sampling to achieve conceptual and theoretical saturation. Data were collected through interviews, observation, focus group discussion, and document reviews. Data were analyzed by Strauss and Corbin's (2008) recommended approach. RESULTS: Transcribed data from 26 interviews (managers, health care providers, and receivers), field notes, and other documents were analyzed, and 1,652 open codes were identified. The codes were categorized, using constant comparative analysis, into five main categories including reactive exposure, subsiding emotions, need for comprehensive health recovery, improvement of normalization (new normality achievement), and contextual factors. The process of life recovery after disaster was also explored. CONCLUSIONS: The results clarified a deep perception of participants' experiences after disaster. The path of life recovery after disasters involves participants' striving to achieve a comprehensive health recovery, which starts with the need for all-inclusive health recovery as a main concern; this is the motivator for a responding strategy. This strategy is participatory, and the process is progressive; achievement of a new normality is the final goal, with new development and levels of empowerment. PMID- 27703798 TI - Umbelliprenin is Potentially Toxic Against the HT29, CT26, MCF-7, 4T1, A172, and GL26 Cell Lines, Potentially Harmful Against Bone Marrow-Derived Stem Cells, and Non-Toxic Against Peripheral Blood Mononuclear Cells. AB - BACKGROUND: Resistance to chemotherapy is a growing concern, thus natural anticancer agents are drawing the attention of many scientists and clinicians. One natural anticancer agent, umbelliprenin, is a coumarin produced by many species of Ferula. OBJECTIVES: We aimed to examine the inhibitory effect of umbelliprenin on human and mouse bone marrow-derived stem cells (BMDSCs), peripheral blood mononuclear cells (PBMCs), and different cancer cell lines. MATERIALS AND METHODS: In this in vitro experimental study, the HT29, CT26, MCF 7, 4T1, A172, and GL26 cancer cells and human and mouse BMDSCs and PBMCs were cultured in RPMI-1640 medium supplemented with 10% fetal bovine serum (FBS), incubated at 37 degrees C for 24 hours in a 5% CO2 atmosphere, and then were treated with different concentrations of umbelliprenin dissolved in dimethyl sulfoxide (DMSO) (3, 6, 12, 25, 50, 100, and 200 ug/mL) for 24, 48, and 72 hours at 37 degrees C. Each experiment was performed in triplicate. Finally, the cell survival rate was assessed by MTT assay. The IC50 values were calculated based on the log values using GraphPad Prism version 5 software for windows (La Jolla CA, USA) and were expressed as mean +/- SEM. RESULTS: Umbelliprenin inhibited the cancer cells in a concentration-dependent (P < 0.05) but not time-dependent manner (P > 0.05). The most sensitive and resistant cell lines at the 24-hour incubation time were 4T1 (IC50, 30.9 +/- 3.1 ug/mL) and A172 (IC50, 51.9 +/- 6.7 ug/mL); at the 48-hour incubation time: 4T1 (IC50, 30.6 +/- 2.6 ug/mL) and CT26 (IC50, 53.2 +/- 3.6 ug/mL); and at the 72-hour incubation time: HT29 (IC50, 37.1 +/- 1.4 ug/mL) and 4T1 (IC50, 62.2 +/- 4.8 ug/mL). Both human and mouse BMDSCs showed the highest resistance at the 24-hour incubation time (IC50s, 254.7 +/- 21 and 204.4 +/- 4.5 ug/mL, respectively) and the highest sensitivity at the 72-hour incubation time (IC50s, 120.4 +/- 5 and 159.0 +/- 7.3 ug/mL, respectively). The PBMCs of both human and mouse origin revealed very strong resistance to the studied concentrations of umbelliprenin (IC50s ranging from 713.5 +/- 499.1 to 6651 +/- 3670.7 ug/mL). CONCLUSIONS: Our findings indicate that umbelliprenin exhibits concentration-dependent inhibitory effects on various cell types; it is potentially toxic against the HT29, CT26, MCF-7, 4T1, A172, and GL26 cell lines, potentially harmful against BMDSCs, and non-toxic against PBMCs. Therefore, if our results are approved in the future, umbelliprenin can be an appropriate candidate for developing treatments against different cancers. PMID- 27703799 TI - Psychometric Properties of the Iranian Version of a Postpartum Women's Quality of Life Questionnaire (PQOL): A Methodological Study. AB - BACKGROUND: There are some specific measures for the evaluation of postpartum quality of life, and each have some limitations. OBJECTIVES: This study investigated the validity and reliability of the Persian version of a postpartum women's quality of life (PQOL) questionnaire at the eighth week of postpartum. PATIENTS AND METHODS: This was a methodological research, and subjects were 500 women, ages 18 - 42, eight weeks postpartum, randomly selected from half of the public centers in Tabriz, Iran, who completed questionnaires in a self administered manner. Data was collected during a two-month period during 2014 - 2015. A standard forward - backward translation procedure was used to translate the English version of the PQOL into Persian. Content, construct, discriminant, and criterion validity was assessed. The reliability was evaluated by internal consistency and test-retest reliability. RESULTS: The PQOL showed good content validity; content validity ratio (CVR) ranged from 0.67 to 1.00 and content validity index (CVI) ranged from 0.78 to 1.00. Construct validity evaluation by exploratory factor analysis (EFA) led to extraction of six factors from the data. Due to the lack of theoretical justification for items' relocation in the extracted factors and poor-fitting indices obtained by confirmatory factor analysis (CFA), the exploratory model was eliminated, and the original model was presented and incorporated into the CFA, indicating an acceptable fit for the model (root mean square error of approximation [RMSEA] = 0.038 [0.034; 0.042]; comparative fit index [CFI] = 0.90; normed fit index [NFI] = 0.80; non-normed fit index [NNFI] = 0.90; incremental fit index [IFI] = 0.90). The intergroup differences in total and all dimensions of the PQOL, except for social support, indicated the discrimination ability of the questionnaire. The questionnaire indicated a medium correlation with the short form health survey (SF-12) questionnaire (r >= 0.50). Cronbach's alpha coefficient (0.70 - 0.88) indicated a good internal consistency, and the intraclass correlation coefficients (0.87 - 0.92) showed good test - retest reliability. CONCLUSIONS: The findings of this study confirmed the validity and reliability of the Iranian version of the PQOL questionnaire in Iranian women as a specific measure to evaluate the women's quality of life. PMID- 27703800 TI - Resilience of Patients With Chronic Physical Diseases: A Systematic Review and Meta-Analysis. AB - CONTEXT: Resilience can be seen as an adaption to stress, such as that caused by health problems or disease, that attenuates the negative effects of stress. The present research performed a systematic review and meta-analysis to study resilience scores among adults diagnosed with chronic physical diseases. EVIDENCE ACQUISITION: Electronic databases, including Persian language (scientific information database [SID], IranMedex, Magiran, IranDoc, and Medlib) and English language (Google Scholar, Science Direct, PubMed, Pre-Quest, and Scopus), were searched. Fifteen articles were found using the keywords disease or chronic disease, resilience or resiliency, and illness, either alone or in combination, both in Persian and English languages. Data analysis was carried out through meta analysis (random-effects model), and heterogeneity was investigated by subgroup and meta-regression analyses. The data were analyzed in STAT software (12.0). RESULTS: The mean resilience score of the chronic disease patients (n = 3369) was 74.6 (95% CI: 51.8 - 97.4). In terms of diseases, the mean resilience score of cancer patients was 79.6 (95% CI: 48.3 - 111.1), whereas it was 79.6 for cardiovascular disease patients (95% CI: 45.8 - 113.3) and 64.6 for patients with other diseases (95% CI: 6.6 - 122.7). There was no relationship between the resilience of chronic disease patients and the year of the study (P = 0.711) and the sample size in the studies (P = 0.351). CONCLUSIONS: The mean resilience score of the patients was less than that of healthy individuals. As resilience can be acquired at any stage of life, irrespective of age and disease status, there is a need for training to improve resilience among patients through educational programs. PMID- 27703801 TI - Trans-4 Portal as a New Portal for Accessing the Lunate in Wrist Arthroscopy: a Cadaveric Study. AB - BACKGROUND: Evolving wrist arthroscopy requires creating new portals, and creating portals reciprocally leads to increased indications for arthroscopic wrist procedures. To facilitate access to the lunate bone and fossa for new arthroscopic procedures, a new portal was used. This is a cadaveric study of this portal. OBJECTIVES: In this cadaveric study, we evaluated a portal in wrist arthroscopy for procedures involving the lunate bone and lunate fossa. MATERIALS AND METHODS: Seventeen wrists from 10 fresh cadavers were included in this study. After diagnostic arthroscopy, a portal (Trans-4) was made through the fourth extensor compartment, exactly along the lunate's long axis under direct visualization from the 3-4 portal. Strand retractors were used to protect the extensor tendons and posterior capsule. Lunate bone core decompression and osteoscopy were done through the portal. At the end of the procedure, the position of the decompression hole in the lunate and any possible injury to the extensor tendons, distal radius cartilage, lunate cartilage, and perilunate ligaments were investigated. RESULTS: Lunate bone decompression was performed successfully in all cases using the trans-4 portal. In 15 wrists, the lunate hole was located in the middle third. In the other two wrists, it was located slightly radial in one case and slightly on the ulnar side in the other case. There was no cortical penetration during decompression, and no extensor tendon, superficial nerve branches, or peri-lunate ligament injuries were observed. CONCLUSIONS: The trans-4 portal could be a safe working portal in wrist arthroscopy that enables access to the lunate bone and lunate fossa. PMID- 27703802 TI - Treatment of Distal Radius Fracture Nonunion With Posterior Interosseous Bone Flap. AB - BACKGROUND: Nonunion of distal radius fractures is disabling. Treatment is difficult and the results are not predictable. However, posterior interosseous bone flap (PIBF) has been successful in treating forearm nonunion. OBJECTIVES: To treat distal radius fracture nonunion with PIBF as a new procedure. PATIENTS AND METHODS: This prospective non-randomized cohort study was performed at two hospitals in Tehran between January 2011 and September 2015. PIBFs were applied in nine patients (10 nonunions) with a mean age of 55 years. Union success rate, grip strength, wrist range of motion, and forearm rotation were then evaluated. RESULTS: Although four of the patients had a history of infection, all participants achieved fracture union at a mean time of 3.8 months. Grip strength improved by 12.4 kg. There was also 36 degrees improvement in wrist flexion, 20 degrees improvement in wrist extension, 60 degrees improvement in forearm supination, and 46 degrees improvement in forearm pronation. The range of motion and grip strength improvements were significant. CONCLUSIONS: Pedicled PIBF is a new option for treating distal radius fracture nonunion. The results are predictable in achieving union and good function, and this technique can be successfully used in cases with extensive soft-tissue damage or infection.

AB - The retinal fractal dimension (FD) is a measure of vasculature branching pattern complexity. FD has been considered as a potential biomarker for the detection of several diseases like diabetes and hypertension. However, conflicting findings were found in the reported literature regarding the association between this biomarker and diseases. In this paper, we examine the stability of the FD measurement with respect to (1) different vessel annotations obtained from human observers, (2) automatic segmentation methods, (3) various regions of interest, (4) accuracy of vessel segmentation methods, and (5) different imaging modalities. Our results demonstrate that the relative errors for the measurement of FD are significant and FD varies considerably according to the image quality, modality, and the technique used for measuring it. Automated and semiautomated methods for the measurement of FD are not stable enough, which makes FD a deceptive biomarker in quantitative clinical applications.

PMID- 27703806 TI - Schoolchildren with Learning Difficulties Have Low Iron Status and High Anemia Prevalence. AB - Background. In developing countries there is high prevalence of iron deficiency anemia, which reduces cognitive performance, work performance, and endurance; it also causes learning difficulties and negative impact on development for infant population. Methods. The study concerns a case-control study; data was collected from an appropriate sample consisting of schoolchildren aged 8 years. The sample was divided into two subgroups: those with deficient initial reading skills (DIRS) (case) and those without (control). Blood samples were taken to analyze hemoglobin and serum ferritin levels. These results were then used to compare the two groups with Student's t-test. Association between DIRS and anemia was analyzed using odds ratio (OR). Results. Hemoglobin and serum ferritin levels of schoolchildren with DIRS were statistically lower when compared to those without, hemoglobin p = 0.02 and serum ferritin p = 0.04. DIRS was statistically associated with a risk of anemia with a weighted OR of 1.62. Conclusions. In this study, schoolchildren with DIRS had lower hemoglobin and serum ferritin levels when compared to those without. PMID- 27703805 TI - Role of Gut Microbiota in the Aetiology of Obesity: Proposed Mechanisms and Review of the Literature. AB - The aetiology of obesity has been attributed to several factors (environmental, dietary, lifestyle, host, and genetic factors); however none of these fully explain the increase in the prevalence of obesity worldwide. Gut microbiota located at the interface of host and environment in the gut are a new area of research being explored to explain the excess accumulation of energy in obese individuals and may be a potential target for therapeutic manipulation to reduce host energy storage. Several mechanisms have been suggested to explain the role of gut microbiota in the aetiology of obesity such as short chain fatty acid production, stimulation of hormones, chronic low-grade inflammation, lipoprotein and bile acid metabolism, and increased endocannabinoid receptor system tone. However, evidence from animal and human studies clearly indicates controversies in determining the cause or effect relationship between the gut microbiota and obesity. Metagenomics based studies indicate that functionality rather than the composition of gut microbiota may be important. Further mechanistic studies controlling for environmental and epigenetic factors are therefore required to help unravel obesity pathogenesis. PMID- 27703807 TI - The Development of Intensive Care Unit Acquired Hypernatremia Is Not Explained by Sodium Overload or Water Deficit: A Retrospective Cohort Study on Water Balance and Sodium Handling. AB - Background. ICU acquired hypernatremia (IAH, serum sodium concentration (sNa) >= 143 mmol/L) is mainly considered iatrogenic, induced by sodium overload and water deficit. Main goal of the current paper was to answer the following questions: Can the development of IAH indeed be explained by sodium intake and water balance? Or can it be explained by renal cation excretion? Methods. Two retrospective studies were conducted: a balance study in 97 ICU patients with and without IAH and a survey on renal cation excretion in 115 patients with IAH. Results. Sodium intake within the first 48 hours of ICU admission was 12.5 [9.3 17.5] g in patients without IAH (n = 50) and 15.8 [9-21.9] g in patients with IAH (n = 47), p = 0.13. Fluid balance was 2.3 [1-3.7] L and 2.5 [0.8-4.2] L, respectively, p = 0.77. Urine cation excretion (urine Na + K) was < sNa in 99 out of 115 patients with IAH. Severity of illness was the only independent variable predicting development of IAH and low cation excretion, respectively. Conclusion. IAH is not explained by sodium intake or fluid balance. Patients with IAH are characterized by low urine cation excretion, despite positive fluid balances. The current paradigm does not seem to explain IAH to the full extent and warrants further studies on sodium handling in ICU patients. PMID- 27703809 TI - Hippocampography Guides Consistent Mesial Resections in Neocortical Temporal Lobe Epilepsy. AB - Background. The optimal surgery in lesional neocortical temporal lobe epilepsy is unknown. Hippocampal electrocorticography maximizes seizure freedom by identifying normal-appearing epileptogenic tissue for resection and minimizes neuropsychological deficit by limiting resection to demonstrably epileptogenic tissue. We examined whether standardized hippocampal electrocorticography (hippocampography) guides resection for more consistent hippocampectomy than unguided resection in conventional electrocorticography focused on the lesion. Methods. Retrospective chart reviews any kind of electrocorticography (including hippocampography) as part of combined lesionectomy, anterolateral temporal lobectomy, and hippocampectomy over 8 years . Patients were divided into mesial (i.e., hippocampography) and lateral electrocorticography groups. Primary outcome was deviation from mean hippocampectomy length. Results. Of 26 patients, fourteen underwent hippocampography-guided mesial temporal resection. Hippocampography was associated with 2.6 times more consistent resection. The range of hippocampal resection was 0.7 cm in the mesial group and 1.8 cm in the lateral group (p = 0.01). 86% of mesial group versus 42% of lateral group patients achieved seizure freedom (p = 0.02). Conclusions. By rationally tailoring excision to demonstrably epileptogenic tissue, hippocampography significantly reduces resection variability for more consistent hippocampectomy than unguided resection in conventional electrocorticography. More consistent hippocampal resection may avoid overresection, which poses greater neuropsychological risk, and underresection, which jeopardizes postoperative seizure freedom. PMID- 27703808 TI - Depressive Symptoms among Latino Sexual Minority Men and Latina Transgender Women in a New Settlement State: The Role of Perceived Discrimination. AB - Background. Little is known about the role of discrimination on depression among Latino sexual and gender identity minorities. This manuscript examined the relationship between ethnic/racial discrimination and sexual discrimination on clinically significant depressive symptoms among Latino sexual minority men (i.e., gay and bisexual men and other men who have sex with men) and Latina transgender women. Methods. A community-based participatory research partnership recruited participants (N = 186; 80.6% cisgender men) in North Carolina to a social network-based HIV intervention. Using baseline data, we quantified the amount of perceived discrimination and conducted mixed-effects logistic regression analyses to examine correlates of clinically significant depressive symptoms. Results. A high percentage of participants reported ethnic/racial discrimination (73.7%) and sexual discrimination (53.8%). In the multivariable models, ethnic/racial discrimination, sexual discrimination, masculinity, fatalism, and social support were significantly associated with clinically significant depressive symptoms. Discussion. Improving mental health requires multilevel interventions that address pertinent individual, interpersonal, and system level factors. PMID- 27703810 TI - Relatives to Critically Ill Patients Have No Sense of Coherence: A Quality Improvement Article Using Mixed Methods. AB - Aims and Objective. To investigate the relatives' satisfaction and involvement on a general surgery ward regarding the critically ill patient. Introduction. Relatives to critically ill patients are affected both physically and mentally during the hospitalization of a family member. Research has shown that relatives do not always receive the attention they need from health professionals. There is a lack of studies that focus on relatives' satisfaction and involvement during their family members' hospitalization. Design. A mixed methods design was chosen. Methods. A quantitative study was conducted with 27 relatives to critically ill patients. All participated in a questionnaire and out of the 27 relatives, six participated in qualitative in-depth interviews. Results. The questionnaire revealed that relatives were dissatisfied with care and involvement. For further exploration of the dissatisfaction, a qualitative approach was used and the in depth interviews revealed three themes: lack of continuity and structure, responsibility of coordination, and relatives feeling left on their own with no guiding and support. Conclusion. Health professionals' key role in relation to relatives must be guidance and support. Thereby, relatives can gain a sense of coherence during the hospitalization of a critically ill patient, which can lead to a greater satisfaction and thereby better support for the patient.

PMID- 27703812 TI - Assessment and Predicting Factors of Repeated Brain Computed Tomography in Traumatic Brain Injury Patients for Risk-Stratified Care Management: A 5-Year Retrospective Study. AB - Background and Objective. To determine the value of repeated brain CT in TBI cases for risk-stratified care management (RSCM) and to identify predicting factors which will change the neurosurgical management after repeated brain CTs. Methods. A 5-year retrospective study from January 2009 to August 2013 was conducted. The primary outcome was the value of repeated brain CT in TBI cases. The secondary outcome is to identify predicting factors which will change the neurosurgical management after repeated brain CTs. Results. There were 145 consecutive patients with TBI and repeated brain CT after initial abnormal brain CT. Forty-two percent of all cases (N = 61) revealed the progression of intracranial hemorrhage after repeated brain CT. In all 145 consecutive patients, 67.6% of cases (N = 98) were categorized as mild TBI. For mild head injury, 8.2% of cases (N = 8) had undergone neurosurgical management after repeated brain CT. Only 1 from 74 mild TBI patients with repeated brain CT had neurosurgical intervention. Clopidogrel and midline shift more than 2 mm on initial brain CT were significant predicting factors to indicate the neurosurgical management in mild TBI cases. Conclusion. Routine repeated brain CT for RSCM had no clinical benefit in mild TBI cases. PMID- 27703813 TI - Sex Differences in Severity, Social Functioning, Adherence to Treatment, and Cognition of Adolescents with Schizophrenia. AB - Background. Previous studies have reported sex differences in the clinical presentation and outcome of adult patients with schizophrenia; the aim of present study was to compare the clinical characteristics, social functioning, adherence to treatment, and cognition of adolescents with this diagnosis in a six-month followup. Methods. A total of 87 adolescents with a DSM-IV diagnosis of schizophrenia or schizophreniform disorder were evaluated with the Positive and Negative Symptoms Scale (PANSS), the Matrics Consensus Cognitive Battery (MCCB), Personal and Social Performance Scale (PSP), and the Rating of Medication Influences (ROMI). Results. Both groups showed a similar improvement in all PANSS factors and in the PSP scores during the followup. Males better adhered to treatment. Females displayed better results in the area of social cognition (F = 6.3, df = 2,52, and p = 0.003) and attention/vigilance (F = 8.3, df = 2,51, and p = 0.001). Conclusions. Male and female adolescents showed similar clinical presentation and functioning but a different pattern of cognitive improvement and adherence to treatment. This trial is registered with Clinicaltrials.gov II3/02/0811.?. PMID- 27703814 TI - Cloning, Sequencing, and the Expression of the Elusive Sarcomeric TPM4alpha Isoform in Humans. AB - In mammals, tropomyosin is encoded by four known TPM genes (TPM1, TPM2, TPM3, and TPM4) each of which can generate a number of TPM isoforms via alternative splicing and/or using alternate promoters. In humans, the sarcomeric isoform(s) of each of the TPM genes, except for the TPM4, have been known for a long time. Recently, on the basis of computational analyses of the human genome sequence, the predicted sequence of TPM4alpha has been posted in GenBank. We designed primer-pairs for RT-PCR and showed the expression of the transcripts of TPM4alpha and a novel isoform TPM4delta in human heart and skeletal muscle. qRT-PCR shows that the relative expression of TPM4alpha and TPM4delta is higher in human cardiac muscle. Western blot analyses using CH1 monoclonal antibodies show the absence of the expression of TPM4delta protein (~28 kDa) in human heart muscle. 2D western blot analyses with the same antibody show the expression of at least nine distinct tropomyosin molecules with a mass ~32 kD and above in adult heart. By Mass spectrometry, we determined the amino acid sequences of the extracted proteins from these spots. Spot "G" reveals the putative expression of TPM4alpha along with TPM1alpha protein in human adult heart.

PMID- 27703817 TI - Conservative Treatment of Carpometacarpal Dislocation of the Three Last Fingers. AB - Posterior carpometacarpal (CMC) dislocation is a rare condition. Treatment is usually surgical though no strict consensus can be found upon literature review. If diagnosed early and no associated fractures are found, CMC dislocation could benefit from conservative treatment comprising closed reduction and splint immobilisation. We report the case of a 26-year-old man diagnosed with a posterior dislocation of the third, fourth, and fifth CMC joints after a fall of 1.5 meters, treated by external reduction under procedural sedation and immobilisation with a cast for 6 weeks. Evolution was excellent with no relapse observed during follow-up. Our aim is to increase physician awareness of CMC dislocation so that they seek this injury in the emergency department. Unrecognised CMC dislocation can lead to neurovascular injuries as well as chronic instability and early articular degeneration. PMID- 27703819 TI - A Case of Mycobacterium riyadhense in an Acquired Immune Deficiency Syndrome (AIDS) Patient with a Suspected Paradoxical Response to Antituberculosis Therapy. AB - A 30-year-old male patient with acquired immune deficiency syndrome (AIDS) on highly active antiretroviral therapy (HAART) presented with clinical picture suggestive of pulmonary tuberculosis. He was commenced on antituberculosis therapy (ATT) with signs of improvement. Then he developed cervical lymph node abscess which was drained. Steroid was started for presumed paradoxical response to ATT which results in clinical regression. The culture result revealed Mycobacterium riyadhense. This report addresses the rarity of this bacteria in medical literature. It reviews clinical presentations and medical treatment particularly in the setting of coinfections. PMID- 27703818 TI - Disseminated Cryptococcal Disease in a Patient with Chronic Lymphocytic Leukemia on Ibrutinib. AB - Cryptococcus is a unique environmental fungus that can cause disease most often in immunocompromised individuals with defective cell-mediated immunity. Chronic lymphocytic leukemia (CLL) is not known to be a risk factor for cryptococcal disease although cases have been described mainly in patients treated with agents that suppress cell-mediated immunity. Ibrutinib is a new biologic agent used for treatment of CLL, mantle cell lymphoma, and Waldenstrom's macroglobulinemia. It acts by inhibiting Bruton's tyrosine kinase, a kinase downstream of the B-cell receptor critical for B-cell survival and proliferation. Ibrutinib use has not been associated previously with cryptococcal disease. However, recent evidence suggested that treatments aimed at blocking the function of Bruton's tyrosine kinase could pose a higher risk for cryptococcal infection in a mice model. Here, we report the first case of disseminated cryptococcal disease in a patient with CLL treated with ibrutinib. When evaluating possible infection in CLL patients receiving ibrutinib, cryptococcal disease, which could be life threatening if overlooked, could be considered. PMID- 27703820 TI - Therapeutic Drug Monitoring of Meropenem in Neonate with Necrotizing Enterocolitis: A Challenge. AB - Necrotizing enterocolitis (NEC) continues to be a major cause of neonatal morbidity and mortality. We describe the added value of therapeutic drug monitoring by presenting the case of a preterm infant with severe NEC treated with meropenem. Dosing strategy will achieve adequate patient outcome when treating pathogens with elevated MIC. As safe as meropenem is, there are not enough data for 40 mg/kg, every 8 h infused over 4 h; accordingly, strict monitoring of blood levels is mandatory. Based on our findings, a 4 h prolonged infusion of 40 mg/kg meropenem, every 8 h, will achieve an adequate patient outcome. PMID- 27703821 TI - External Otitis: An Unusual Presentation in Neonates. AB - Acute otitis externa (AOE) is an infection of the external auditory canal, the auricle, and the outer surface of the tympanic membrane. Although AOE is one of the most common otologic conditions encountered in pediatric population, it is known to primarily affect children older than 2 years. We report a case of AOE caused by Staphylococcus aureus in a 23-day-old neonate. A 23-day-old female infant presented to our neonatology clinic with irritability and discharge from the right ear. There were yellow otorrhea, mild erythema, and edema of right external ear canal. There was no sign of otitis media on otoscopy. The results of laboratory tests were insignificant. The discharge culture grew colonies of methicillin-sensitive Staphylococcus aureus. After 48 hours of treatment with intravenous cloxacillin, significant improvement was observed. The present case highlights an unusual presentation of staphylococcal infection in a neonate. This is the first case of methicillin-sensitive Staphylococcus aureus otitis externa in an immunocompetent newborn.

PMID- 27703824 TI - Spontaneous Recurrent Hemarthrosis of the Knee: A Report of Two Cases with a Source of Bleeding Detected during Arthroscopic Surgery of the Knee Joint. AB - We report two cases of the spontaneous recurrent hemarthrosis of the knee. In these cases lateral meniscus was severely torn and a small tubular soft tissue with pulsation was identified on the synovium in the posterolateral corner during arthroscopic surgery of the knee joint. Gentle grasping of this tissue by forceps led to pulsating bleeding, which stopped by electrocoagulation. This soft tissue was considered a source of bleeding, since no recurrence of hemarthrosis was observed for more than four years after surgery. It was highly probable that this soft tissue was the ruptured end of the lateral inferior genicular artery or its branch. This case report strongly supports the theory that the bleeding from the peripheral arteries of the posterior portion of the lateral meniscus is the cause of spontaneous recurrent hemarthrosis of the knee. PMID- 27703825 TI - Solitary Spinal Epidural Metastasis from Gastric Cancer. AB - Solitary epidural space metastasis of a malignant tumor is rare. We encountered a 79-year-old male patient with solitary metastatic epidural tumor who developed paraplegia and dysuria. The patient had undergone total gastrectomy for gastric cancer followed by chemotherapy 8 months priorly. The whole body was examined for suspected metastatic spinal tumor, but no metastases of the spine or important organs were observed, and a solitary mass was present in the thoracic spinal epidural space. The mass was excised for diagnosis and treatment and was histopathologically diagnosed as metastasis from gastric cancer. No solitary metastatic epidural tumor from gastric cancer has been reported in English. Among the Japanese, 3 cases have been reported, in which the outcome was poor in all cases and no definite diagnosis could be made before surgery in any case. Our patient developed concomitant pneumonia after surgery and died shortly after the surgery. When a patient has a past medical history of malignant tumor, the possibility of a solitary metastatic tumor in the epidural space should be considered. PMID- 27703826 TI - Entrapment of Common Peroneal Nerve by Surgical Suture following Distal Biceps Femoris Tendon Repair. AB - We describe entrapment of the common peroneal nerve by a suture after surgical repair of the distal biceps femoris tendon. Complete rupture of the distal biceps femoris tendon of a 16-year-old male athlete was surgically repaired. Postoperative common peroneal nerve palsy was evident, but conservative treatment did not cause any neurological improvement. Reexploration revealed that the common peroneal nerve was entrapped by the surgical suture. Complete removal of the suture and external neurolysis significantly improved the palsy. The common peroneal nerve is prone to damage as a result of its close proximity to the biceps femoris tendon and it should be identified during surgical repair of a ruptured distal biceps femoris tendon.

Anticoagulant therapy was applied to prevent thromboembolism and he is still going on follow-up without any complaint. PMID- 27703827 TI - Chronic Invasive Nongranulomatous Fungal Rhinosinusitis in Immunocompetent Individuals. AB - Chronic invasive nongranulomatous fungal rhinosinusitis is a well-described but uncommon type of fungal rhinosinusitis (FRS). While the prevalence of chronic FRS is 0.11% in healthy individuals, only 1.3% of them are in nongranulomatous invasive nature. The majority of the cases in the literature have been reported from developing countries mostly located in the tropical regions, as typically occurring in the background of diabetes mellitus or corticosteroid treatment. The current paper reports four consecutive cases, who were diagnosed within a short period of six months at a single center of a country located outside the tropical climate zone. None of the patients had a comorbid disease that may cause immune suppression or a history of drug use. The only risk factor that may have a role in development of chronic invasive nongranulomatous FRS was that all of our patients were people working in greenhouse farming. Three cases underwent endoscopic sinus surgery, and one case underwent surgery with both endoscopic and external approaches. Systemic antifungal therapy was initiated in all cases in the postoperative period with voriconazole 200 mg orally twice a day. All patients achieved a complete clinical remission. Chronic invasive nongranulomatous FRS should be kept in mind in the presence of long-standing nonspecific sinonasal symptoms in immunocompetent individuals, particularly with a history of working in greenhouse farming. PMID- 27703829 TI - Development of Tinnitus at a Low Dose of Sertraline: Clinical Course and Proposed Mechanisms. AB - Introduction. Serotonin is involved in filtering of auditory stimuli. Cochlear input is processed through complex interactions between serotonergic, glutamatergic, and GABAergic neurotransmitter systems. Options for treatment of tinnitus include selective serotonin reuptake inhibitors (SSRIs); however in rare instances this symptom may occur as a side effect of this class of medications. Case Presentation. A 50-year-old woman developed bilateral tinnitus after several weeks of being treated with sertraline 50 mg. She had been on a long-standing daily dose of aspirin 325 mg which had been discontinued shortly before starting sertraline. Medical work-up was negative for her symptom. Shortly after discontinuation of the medication, her tinnitus subsided completely. Discussion. Tinnitus is a rare side effect of sertraline and may be related to particular distribution of serotonin receptor subtypes within the auditory system, and serotonergic agents may reinforce or desensitize the activity of different receptors. Also, there may be a priming effect of salicylate agents on the auditory system, predisposing particular patients to be more sensitive to how auditory stimuli are processed.

AB - Eosinophilic polymyositis (EPM) is part of a rare disorder, eosinophilic myopathies (EM), which is a form of polymyositis characterized by the presence of eosinophils in muscle biopsy sections and occasionally blood eosinophilia. Herein, we are presenting an interesting case of eosinophilic polymyositis presenting with muscle pain with no other organ systems involved. PMID- 27703831 TI - Spontaneous Septic Arthritis of Pubic Symphysis in an Elite Athlete. AB - Septic arthritis of the pubic symphysis is a potentially severe disease. Athletes are at risk of this form of spontaneous arthritis, as inflammation of the pubic bone due to muscular stress is relatively common. Oedema due to inflammation might predispose to infection through bacteraemia or local bacterial translocation. Suspicion should be raised when an athlete complains of groin pain and has signs of infection (i.e., fever, elevated white blood cell count, and elevated C-reactive protein). Diagnosis is made by imaging showing signs of inflammation combined with positive (blood) cultures. Broad spectrum antibiotics should be started upon suspicion and adjusted according to cultures. An abscess causing clinical deterioration under antibiotic treatment is an indication for invasive intervention (i.e., surgical or image-guided drainage). This is the first case of spontaneous septic arthritis of the pubic symphysis in an athlete requiring surgical and additional image-guided drainage.

AB - Laparoscopic cholecystectomy for acute cholecystitis and cholelithiasis is one of the most common operations performed in the United States. Inadvertent perforation and spillage of gallbladder contents are not uncommon. The potential impact of subsequent retained gallstones is understated. We present the case of an intraperitoneal gallstone retained from a previous cholecystectomy eroding into the bowel and leading to intraluminal mechanical bowel obstruction requiring operative intervention. This case illustrates the potential risks of retained gallstones and reinforces the need to diligently collect any dropped stones at the time of initial operation.

The diagnosis is difficult and any delay can result in ischemia and necrosis of both organs. We present a case of a 13-year-old girl, previously operated on for anterior diaphragmatic hernia and intrathoracic gastric volvulus, that presented to our service for a subdiaphragmatic gastric volvulus recurrence associated with a wandering spleen. In this report we reviewed the literature, analyzing the clinical presentation, diagnostic assessment, and treatment options of both conditions, in particular in the case associated with diaphragmatic hernia. PMID- 27703835 TI - Strongyloides Hyperinfection Syndrome Combined with Cytomegalovirus Infection. AB - The mortality in Strongyloides hyperinfection syndrome (SHS) is alarmingly high. This is particularly common in bone marrow, renal, and other solid organ transplant (SOT) patients, where figures may reach up to 50-85%. Immunosuppressives, principally corticosteroids, are the primary triggering factor. In general, the clinical features of Strongyloides stercoralis hyperinfection are nonspecific; therefore, a high index of suspicion is required for early diagnosis and starting appropriate therapy. Although recurrent Gram negative sepsis and meningitis have been previously reported, the combination of both cytomegalovirus (CMV) and strongyloidiasis had rarely been associated. We here describe a patient who survived SHS with recurrent Escherichia coli (E. coli) urosepsis and CMV infection.

PMID- 27703840 TI - Continuum beliefs in the stigma process regarding persons with schizophrenia and depression: results of path analyses. AB - BACKGROUND: Individuals with mental illness often experience stigmatization and encounter stereotypes such as being dangerous or unpredictable. To further improve measures against psychiatric stigma, it is of importance to understand its components. In this study, we attend to the step of separation between "us" and "them" in the stigma process as conceptualized by Link and Phelan. In using the belief in continuity of mental illness symptoms as a proxy for separation, we explore its associations with stereotypes, emotional responses and desire for social distance in the stigma process. METHODS: Analyses are based on a representative survey in Germany. Vignettes with symptoms suggestive of schizophrenia (n = 1,338) or depression (n = 1,316) were presented to the respondents, followed by questions on continuum belief, stereotypes, emotional reactions and desire for social distance. To examine the relationship between these items, path models were computed. RESULTS: Respondents who endorsed the continuum belief tended to show greater prosocial reactions (schizophrenia: 0.07; p < 0.001, depression: 0.09; p < 0.001) and less desire for social distance (schizophrenia: -0.13; p < 0.001, depression: -0.14; p < 0.001) toward a person with mental illness. In both cases, agreement with the stereotypes of unpredictability and dangerousness was positively associated with feelings of anger and fear as well as desire for social distance. There were no statistically significant relations between stereotypes and continuum beliefs. DISCUSSION: Assumptions regarding continuum beliefs in the stigma process were only partially confirmed. However, there were associations of continuum beliefs with less stigmatizing attitudes toward persons affected by either schizophrenia or depression. Including information on continuity of symptoms, and thus oppose perceived separation, could prove helpful in future anti-stigma campaigns. PMID- 27703841 TI - Extremely low genetic variability within and among locations of the greenfish holothurian Stichopus chloronotus Brandt, 1835 in Okinawa, Japan. AB - The greenfish sea cucumber Stichopus chloronotus is an economically and ecologically important sea cucumber species throughout its range. This species is widely distributed, inhabiting coral reefs of the Indo-Pacific Ocean. Our study evaluated population genetic structure and levels of genetic diversity in southern Japan. A total of 180 individuals were collected from eight locations from Okinawa and Okinoerabu Islands and sequenced using mitochondrial 16S ribosomal DNA (16S) and nuclear histone H3 (H3) gene. Only three 16S haplotypes were detected (518 bp) with haplotype diversity ranging from 0 to 0.56 and nucleotide diversity from 0 to 0.1%. H3 showed no variation among the studied locations. It is plausible that such results could be due to a shift to asexual reproduction. Additionally, the presence of the species on the east coast of Okinawa could only be detected in one location and all individuals consisted of a single haplotype. Genetic differences between the east and west coasts of Okinawa have been noticed in other coral reef organisms, and attributed to either ecological or biogeographical historical differences between the coasts due to differing levels of isolation during Pleistocene ice ages. Results from the present study should inform management and conservation policies of S. chloronotus in southern Japan. PMID- 27703842 TI - RBioplot: an easy-to-use R pipeline for automated statistical analysis and data visualization in molecular biology and biochemistry. AB - BACKGROUND: Statistical analysis and data visualization are two crucial aspects in molecular biology and biology. For analyses that compare one dependent variable between standard (e.g., control) and one or multiple independent variables, a comprehensive yet highly streamlined solution is valuable. The computer programming language R is a popular platform for researchers to develop tools that are tailored specifically for their research needs. Here we present an R package RBioplot that takes raw input data for automated statistical analysis and plotting, highly compatible with various molecular biology and biochemistry lab techniques, such as, but not limited to, western blotting, PCR, and enzyme activity assays. METHOD: The package is built based on workflows operating on a simple raw data layout, with minimum user input or data manipulation required. The package is distributed through GitHub, which can be easily installed through one single-line R command. A detailed installation guide is available at http://kenstoreylab.com/?page_id=2448. Users can also download demo datasets from the same website. RESULTS AND DISCUSSION: By integrating selected functions from existing statistical and data visualization packages with extensive customization, RBioplot features both statistical analysis and data visualization functionalities. Key properties of RBioplot include: -Fully automated and comprehensive statistical analysis, including normality test, equal variance test, Student's t-test and ANOVA (with post-hoc tests);-Fully automated histogram, heatmap and joint-point curve plotting modules;-Detailed output files for statistical analysis, data manipulation and high quality graphs;-Axis range finding and user customizable tick settings;-High user-customizability.

AB - The alteration of glucose metabolism, through increased uptake of glucose and glutamine addiction, is essential to cancer cell growth and invasion. Increased flux of glucose through the Hexosamine Biosynthetic Pathway (HBP) drives increased cellular O-GlcNAcylation (hyper-O-GlcNAcylation) and contributes to cancer progression by regulating key oncogenes. However, the association between hyper-O-GlcNAcylation and activation of these oncogenes remains poorly characterized. Here, we implement a qualitative modeling framework to analyze the role of the Biological Regulatory Network in HBP activation and its potential effects on key oncogenes. Experimental observations are encoded in a temporal language format and model checking is applied to infer the model parameters and qualitative model construction. Using this model, we discover step-wise genetic alterations that promote cancer development and invasion due to an increase in glycolytic flux, and reveal critical trajectories involved in cancer progression. We compute delay constraints to reveal important associations between the production and degradation rates of proteins. O-linked N-acetylglucosamine transferase (OGT), an enzyme used for addition of O-GlcNAc during O GlcNAcylation, is identified as a key regulator to promote oncogenesis in a feedback mechanism through the stabilization of c-Myc. Silencing of the OGT and c Myc loop decreases glycolytic flux and leads to programmed cell death. Results of network analyses also identify a significant cycle that highlights the role of p53-Mdm2 circuit oscillations in cancer recovery and homeostasis. Together, our findings suggest that the OGT and c-Myc feedback loop is critical in tumor progression, and targeting these mediators may provide a mechanism-based therapeutic approach to regulate hyper-O-GlcNAcylation in human cancer.

AB - Dense Acropora cervicornis aggregations, or patches, have been documented within nearshore habitats in Southeast Florida (SE FL) despite close proximity to numerous anthropogenic stressors and subjection to frequent natural disturbance events. Limited information has been published concerning the distribution and abundance of A. cervicornis outside of these known dense patches. The first goal of this study was to conduct a spatially extensive and inclusive survey (9.78 km2) to determine whether A. cervicornis distribution in the nearshore habitat of SE FL was spatially uniform or clustered. The second goal was to investigate potential relationships between broad-scale seafloor topography and A. cervicornis abundance using high resolution bathymetric data. Acropora cervicornis was distributed throughout the study area, and the Getis-Ord Gi* statistic and Anselin Local Moran's I spatial cluster analysis showed significant clustering along topographic features termed ridge crests. Significant clustering was further supported by the inverse distance weighted surface model. Ordinal logistic regression indicated 1) as distance from a ridge increases, odds of reduced A. cervicornis abundance increases; 2) as topographic elevation increases, odds of increased abundance increases; and 3) as mean depth increases, odds of increased abundance increases. This study provides detailed information on A. cervicornis distribution and abundance at a regional scale and supports modeling its distributions in similar habitats elsewhere throughout the western Atlantic and Caribbean. Acropora cervicornis is frequently observed and in areas an abundant species within the nearshore habitat along the SE FL portion of the Florida Reef Tract (FRT). This study provides a better understanding of local habitat associations thus facilitating appropriate management of the nearshore environment and species conservation. The portion of the FRT between Hillsboro and Port Everglades inlets should be considered for increased management and protection to reduce local stressors. PMID- 27703843 TI - XA21-specific induction of stress-related genes following Xanthomonas infection of detached rice leaves. AB - The rice XA21 receptor kinase confers robust resistance to the bacterial pathogen Xanthomonas oryzaepv. oryzae (Xoo). We developed a detached leaf infection assay to quickly and reliably measure activation of the XA21-mediated immune response using genetic markers. We used RNA sequencing of elf18 treated EFR:XA21:GFP plants to identify candidate genes that could serve as markers for XA21 activation. From this analysis, we identified eight genes that are up-regulated in both in elf18 treated EFR:XA21:GFP rice leaves and Xoo infected XA21 rice leaves. These results provide a rapid and reliable method to assess bacterial rice interactions. PMID- 27703846 TI - Dynamics and stability of directional jumps in the desert locust. AB - Locusts are known for their ability to jump large distances to avoid predation. The jump also serves to launch the adult locust into the air in order to initiate flight. Various aspects of this important behavior have been studied extensively, from muscle physiology and biomechanics, to the energy storage systems involved in powering the jump, and more. Less well understood are the mechanisms participating in control of the jump trajectory. Here we utilise video monitoring and careful analysis of experimental directional jumps by adult desert locusts, together with dynamic computer simulation, in order to understand how the locusts control the direction and elevation of the jump, the residual angular velocities resulting from the jump and the timing of flapping-flight initiation. Our study confirms and expands early findings regarding the instrumental role of the initial body position and orientation. Both real-jump video analysis and simulations based on our expanded dynamical model demonstrate that the initial body coordinates of position (relative to the hind-legs ground-contact points) are dominant in predicting the jumps' azimuth and elevation angles. We also report a strong linear correlation between the jumps' pitch-angular-velocity and flight initiation timing, such that head downwards rotations lead to earlier wing opening. In addition to offering important insights into the bio-mechanical principles of locust jumping and flight initiation, the findings from this study will be used in designing future prototypes of a bio-inspired miniature jumping robot that will be employed in animal behaviour studies and environmental monitoring applications. PMID- 27703847 TI - Genetic diversity of Poa pratensis L. depending on geographical origin and compared with genetic markers. AB - BACKGROUND: Poa pratensis is one of the most common species of meadow grass in Europe. Most cultivars of the species found in Poland were originally derived from its ecotypes. We compared the effectiveness of the RAPD and ISSR methods in assessing the genetic diversity of the selected populations of P. pratensis. We examined whether these methods could be useful for detecting a possible link between the geographical origin of a given population and its assessed genetic variation. METHODS: The molecular markers RAPD and ISSR were used and their efficiency compared using, inter alia, statistical multivariate methods (UPGMA and PCA). RESULTS: The low value of Dice's coefficient (0.369) along with the significantly high percentage of polymorphic products indicates a substantial degree of genetic diversity among the studied populations. Our results found a correlation between the geographical origin of the studied populations and their genetic variations. For ISSR, which proved to be the more effective method in that respect, we selected primers with the greatest differentiating powers correlating to geographical origin. DISCUSSION: The populations evaluated in this study were characterized by a high genetic diversity. This seems to confirm the hypothesis that ecotypes of P. pratensis originating from different regions of Central Europe with different terrain structures and habitat conditions can be a source of great genetic variability. PMID- 27703848 TI - Reproductive ecology and isolation of Psittacanthus calyculatus and P. auriculatus mistletoes (Loranthaceae). AB - BACKGROUND: Relationships between floral biology and pollinator behavior are important to understanding species diversity of hemiparasitic Psittacanthus mistletoes (c. 120 species). We aimed to investigate trait divergence linked to pollinator attraction and reproductive isolation (RI) in two hummingbird pollinated and bird-dispersed Psittacanthus species with range overlap. METHODS: We investigated the phylogenetic relationships, floral biology, pollinator assemblages, seed dispersers and host usage, and the breeding system and female reproductive success of two sympatric populations of P. calyculatus and P. auriculatus, and one allopatric population of P. calyculatus. Flowers in sympatry were also reciprocally pollinated to assess a post-mating component of RI. RESULTS: Hummingbird assemblages differed between calyculatus populations, while allopatric plants of calyculatus opened more but smaller flowers with longer lifespans and produced less nectar than those in sympatry. Bayesian-based phylogenetic analysis indicated monophyly for calyculatus populations (i.e. both populations belong to the same species). In sympatry, calyculatus plants opened more and larger flowers with longer lifespans and produced same nectar volume than those of auriculatus; populations shared pollinators but seed dispersers and host usage differed between species. Nectar standing crops differed between sympatric populations, with lower visitation in calyculatus. Hand pollination experiments indicated a predominant outcrossing breeding system, with fruit set after interspecific pollination two times higher from calyculatus to auriculatus than in the opposite direction. CONCLUSIONS: Given the low genetic differentiation between calyculatus populations, observed trait divergence could have resulted from changes regarding the local communities of pollinators and, therefore, expected divergence for peripheral, allopatric populations. Using RI estimates, there were fewer heterospecific matings than expected by chance in P. calyculatus (RI4A = 0.629) as compared to P. auriculatus (RI4A = 0.20). When considering other factors of ecological isolation that affect co-occurrence, the RI4C values indicate that isolation by hummingbird pollinators was less effective (0.20) than isolation by host tree species and seed dispersers (0.80 and 0.60, respectively), suggesting that host usage is the most important ecological isolation factor between the two species. Accordingly, the absolute and relative cumulative strength values indicated that the host tree species' barrier is currently contributing the most to maintaining these species in sympatry. PMID- 27703845 TI - Identify potential drugs for cardiovascular diseases caused by stress-induced genes in vascular smooth muscle cells. AB - BACKGROUND: Abnormal proliferation of vascular smooth muscle cells (VSMC) is a major cause of cardiovascular diseases (CVDs). Many studies suggest that vascular injury triggers VSMC dedifferentiation, which results in VSMC changes from a contractile to a synthetic phenotype; however, the underlying molecular mechanisms are still unclear. METHODS: In this study, we examined how VSMC responds under mechanical stress by using time-course microarray data. A three phase study was proposed to investigate the stress-induced differentially expressed genes (DEGs) in VSMC. First, DEGs were identified by using the moderated t-statistics test. Second, more DEGs were inferred by using the Gaussian Graphical Model (GGM). Finally, the topological parameters-based method and cluster analysis approach were employed to predict the last batch of DEGs. To identify the potential drugs for vascular diseases involve VSMC proliferation, the drug-gene interaction database, Connectivity Map (cMap) was employed. Success of the predictions were determined using in-vitro data, i.e. MTT and clonogenic assay. RESULTS: Based on the differential expression calculation, at least 23 DEGs were found, and the findings were qualified by previous studies on VSMC. The results of gene set enrichment analysis indicated that the most often found enriched biological processes are cell-cycle-related processes. Furthermore, more stress-induced genes, well supported by literature, were found by applying graph theory to the gene association network (GAN). Finally, we showed that by processing the cMap input queries with a cluster algorithm, we achieved a substantial increase in the number of potential drugs with experimental IC50 measurements. With this novel approach, we have not only successfully identified the DEGs, but also improved the DEGs prediction by performing the topological and cluster analysis. Moreover, the findings are remarkably validated and in line with the literature. Furthermore, the cMap and DrugBank resources were used to identify potential drugs and targeted genes for vascular diseases involve VSMC proliferation. Our findings are supported by in-vitro experimental IC50, binding activity data and clinical trials. CONCLUSION: This study provides a systematic strategy to discover potential drugs and target genes, by which we hope to shed light on the treatments of VSMC proliferation associated diseases. PMID- 27703849 TI - Atlantic salmon (Salmo salar) require increased dietary levels of B-vitamins when fed diets with high inclusion of plant based ingredients. AB - Aiming to re-evaluate current recommendations for nutrient supplementations when Atlantic salmon are fed diets based on plant ingredients, two regression experiments, with parr and post-smolt, were conducted. A control diet was included to evaluate if ingredients supplied sufficient nutrients without any added nutrient package (NP). The nutrient package consisted of vitamins B, C, E, minerals, cholesterol, methionine, taurine and histidine. This paper focus on B vitamins. In parr, growth, health and welfare parameters responded on NP additions, but this was not observed in the seawater stage. During three months of feeding, parr tripled their weight. Parr given diets added the NP above NRC (2011) showed improved protein retention, and reduced liver and viscera indices. Post-smolt fed the same diets during five months showed a doubling of weight, but did not respond to the variation in NP to the same extent as parr. Significant regressions were obtained in body compartments for several of the B-vitamins in the premix. Whole body biotin concentration was unaffected by micronutrient premix level, and mRNA expression of the enzymes dependent of biotin showed only weak increases with increased biotin. Muscle thiamine plateaued at a diet level similar to NRC (2011) recommendation in freshwater, and showed stable values independent on premix addition in seawater. The mRNA expression of the enzyme G6PDH (glucose-6-phosphate dehydrogenase) is sensitive to thiamine availability; results did not indicate any need to add thiamine above levels recommended for fish in general. Niacin showed a steady increase in whole body concentrations as feed niacin increased. Muscle riboflavin peaked at a diet level of 12.4 mg kg-1. Sufficient riboflavin is important to avoid e.g., development of cataract. Cataract was not registered to be any problem, neither in fresh- nor in seawater. Cobalamin (B 12) in muscle and liver was saturated at 0.17 mg kg-1 diet. Muscle pyridoxine showed a dose-dependent level in muscle, and peaked around 10 mg kg -1 diet. White muscle ASAT (asparagine amino transferase) activity steadily increased, with indications of stable values when dietary pyridoxine was around 10-16 mg kg -1 diet. Pantothenic acid increased in gill tissue up to a level of 5.5 mg kg -1 soft gill tissue; at a dietary level of 22 mg kg-1. Improved performance, and coverage of metabolic need for niacin was at a dietary level of 66 mg kg -1, riboflavin 10-12 mg kg-1, pyridoxine 10 mg kg-1 and panthotenic acid 22 mg kg-1. Based on these results, recommended B-vitamin supplementation in plant based diets for Atlantic salmon should be adjusted. PMID- 27703850 TI - Enzymatically crosslinked gelatin hydrogel promotes the proliferation of adipose tissue-derived stromal cells. AB - Gelatin hydrogel crosslinked by microbial transglutaminase (mTG) exhibits excellent performance in cell adhesion, proliferation, and differentiation. We examined the gelation time and gel strength of gelatin/mTG hydrogels in various proportions to investigate their physical properties and tested their degradation performances in vitro. Cell morphology and viability of adipose tissue-derived stromal cells (ADSCs) cultured on the 2D gel surface or in 3D hydrogel encapsulation were evaluated by immunofluorescence staining. Cell proliferation was tested via Alamar Blue assay. To investigate the hydrogel effect on cell differentiation, the cardiac-specific gene expression levelsof Nkx2.5, Myh6, Gja1, and Mef2c in encapsulated ADSCs with or without cardiac induction medium were detected by real-time RT-PCR. Cell release from the encapsulated status and cell migration in a 3D hydrogel model were assessed in vitro. Results show that the gelatin/mTG hydrogels are not cytotoxic and that their mechanical properties are adjustable. Hydrogel degradation is related to gel concentration and the resident cells. Cell growth morphology and proliferative capability in both 2D and 3D cultures were mainly affected by gel concentration. PCR result shows that hydrogel modulus together with induction medium affects the cardiac differentiation of ADSCs. The cell migration experiment and subcutaneous implantation show that the hydrogels are suitable for cell delivery. PMID- 27703852 TI - An early bothremydid (Testudines, Pleurodira) from the Late Cretaceous (Cenomanian) of Utah, North America. AB - BACKGROUND: Bothremydidae is a clade of extinct pleurodiran turtles known from the Cretaceous to Paleogene of Africa, Europe, India, Madagascar, and North and South America. The group is most diverse during the Late Cretaceous to Paleogene of Africa. Little is known, however, about the early evolution of the group. METHODS: We here figure and describe a fossil turtle from early Late Cretaceous deposits exposed at MacFarlane Mine in Cedar Canyon, southwestern Utah, USA. The sediments associated with the new turtle are utilized to infer its stratigraphic provenience and the depositional settings in which it was deposited. The fossil is compared to previously described fossil pleurodires, integrated into a modified phylogenetic analysis of pelomedusoid turtles, and the biogeography of bothremydid turtles is reassessed. In light of the novel phylogenetic hypotheses, six previously established taxon names are converted to phylogenetically defined clade names to aid communication. RESULTS: The new fossil turtle can be inferred with confidence to have originated from a brackish water facies within the late Cenomanian Culver Coal Zone of the Naturita Formation. The fossil can be distinguished from all other previously described pleurodires and is therefore designated as a new taxon, Paiutemys tibert gen. et. sp. nov. Phylogenetic analysis places the new taxon as sister to the European Polysternon provinciale, Foxemys trabanti and Foxemys mechinorum at the base of Bothremydinae. Biogeographic analysis suggests that bothremydids originated as continental turtles in Gondwana, but that bothremydines adapted to near-shore marine conditions and therefore should be seen as having a circum-Atlantic distribution. PMID- 27703851 TI - Evolution history of duplicated smad3 genes in teleost: insights from Japanese flounder, Paralichthys olivaceus. AB - Following the two rounds of whole-genome duplication (WGD) during deuterosome evolution, a third genome duplication occurred in the ray-fined fish lineage and is considered to be responsible for the teleost-specific lineage diversification and regulation mechanisms. As a receptor-regulated SMAD (R-SMAD), the function of SMAD3 was widely studied in mammals. However, limited information of its role or putative paralogs is available in ray-finned fishes. In this study, two SMAD3 paralogs were first identified in the transcriptome and genome of Japanese flounder (Paralichthys olivaceus). We also explored SMAD3 duplication in other selected species. Following identification, genomic structure, phylogenetic reconstruction, and synteny analyses performed by MrBayes and online bioinformatic tools confirmed that smad3a/3b most likely originated from the teleost-specific WGD. Additionally, selection pressure analysis and expression pattern of the two genes performed by PAML and quantitative real-time PCR (qRT PCR) revealed evidence of subfunctionalization of the two SMAD3 paralogs in teleost. Our results indicate that two SMAD3 genes originate from teleost specific WGD, remain transcriptionally active, and may have likely undergone subfunctionalization. This study provides novel insights to the evolution fates of smad3a/3b and draws attentions to future function analysis of SMAD3 gene family. PMID- 27703855 TI - Accuracy of conventional identification methods used for Enterobacteriaceae isolates in three Nigerian hospitals. AB - BACKGROUND: Enterobacteriaceae are ubiquitously present in nature and can be found in the intestinal tract of humans and animals as commensal flora. Multidrug resistant Enterobacteriaceae are increasingly reported and are a threat to public health implicating a need for accurate identification of the isolates to species level. In developing countries, identification of bacteria basically depends on conventional methods: culture and phenotypic methods that hamper the accurate identification of bacteria. In this study, matrix-assisted desorption ionization time of flight mass spectrometry (MALDI-TOF MS) technique was compared to conventional identification techniques. MATERIALS AND METHODS: In total, 147 Enterobacteriaceae isolates were collected from March to May 2015 from three medical microbiology laboratories of hospitals in Edo state, Nigeria, after being tested according to the individual laboratories standard operating procedures. All isolates were stored at -20 degrees C until tested centrally by MALDI-TOF MS. RESULTS: One hundred and forty five (98.6%) isolates had a MALDI Biotyper best score > or =2.0, indicating a secure genus and probable species identification; and 2(1.36%) isolates had a best score <2.0 indicating probable genus identification. Isolates with best scores of > or =2.0 comprised nine genera and 10 species, respectively. A total of 57.2% and 33.1% of isolates identified had agreement between MALDI-TOF MS and conventional techniques for identification at genus and species level, respectively, when analyzing bacteria with MALDI Biotyper best scores > or =2.0. CONCLUSION: The results of our study show that the applied conventional identification techniques for Enterobacteriaceae in the investigated Nigerian hospitals are not very accurate. Use of state-of-the-art identification technologies for microorganisms is necessary to guarantee comparability of bacteriological results. PMID- 27703853 TI - A direct CO2 control system for ocean acidification experiments: testing effects on the coralline red algae Phymatolithon lusitanicum. AB - Most ocean acidification (OA) experimental systems rely on pH as an indirect way to control CO2. However, accurate pH measurements are difficult to obtain and shifts in temperature and/or salinity alter the relationship between pH and pCO2. Here we describe a system in which the target pCO2 is controlled via direct analysis of pCO2 in seawater. This direct type of control accommodates potential temperature and salinity shifts, as the target variable is directly measured instead of being estimated. Water in a header tank is permanently re-circulated through an air-water equilibrator. The equilibrated air is then routed to an infrared gas analyzer (IRGA) that measures pCO2 and conveys this value to a Proportional-Integral-Derivative (PID) controller. The controller commands a solenoid valve that opens and closes the CO2 flush that is bubbled into the header tank. This low-cost control system allows the maintenance of stabilized levels of pCO2 for extended periods of time ensuring accurate experimental conditions. This system was used to study the long term effect of OA on the coralline red algae Phymatolithon lusitanicum. We found that after 11 months of high CO2 exposure, photosynthesis increased with CO2 as opposed to respiration, which was positively affected by temperature. Results showed that this system is adequate to run long-term OA experiments and can be easily adapted to test other relevant variables simultaneously with CO2, such as temperature, irradiance and nutrients. PMID- 27703854 TI - Sex differences in pacing during 'Ultraman Hawaii'. AB - BACKGROUND: To date, little is known for pacing in ultra-endurance athletes competing in a non-stop event and in a multi-stage event, and especially, about pacing in a multi-stage event with different disciplines during the stages. Therefore, the aim of the present study was to examine the effect of age, sex and calendar year on triathlon performance and variation of performance by events (i.e., swimming, cycling 1, cycling 2 and running) in 'Ultraman Hawaii' held between 1983 and 2015. METHODS: Within each sex, participants were grouped in quartiles (i.e., Q1, Q2, Q3 and Q4) with Q1 being the fastest (i.e., lowest overall time) and Q4 the slowest (i.e., highest overall time). To compare performance among events (i.e., swimming, cycling 1, cycling 2 and running), race time in each event was converted in z score and this value was used for further analysis. RESULTS: A between-within subjects ANOVA showed a large sex * event (p = 0.015, eta2 = 0.014) and a medium performance group * event interaction (p = 0.001, eta2 = 0.012). No main effect of event on performance was observed (p = 0.174, eta2 = 0.007). With regard to the sex * event interaction, three female performance groups (i.e., Q2, Q3 and Q4) increased race time from swimming to cycling 1, whereas only one male performance group (Q4) revealed a similar trend. From cycling 1 to cycling 2, the two slower female groups (Q3 and Q4) and the slowest male group (Q4) increased raced time. In women, the fastest group decreased (i.e., improved) race time from swimming to cycling 1 and thereafter, maintained performance, whereas in men, the fastest group decreased race time till cycling 2 and increased it in the running. CONCLUSION: In summary, women pace differently than men during 'Ultraman Hawaii' where the fastest women decreased performance on day 1 and could then maintain on day 2 and 3, whereas the fastest men worsened performance on day 1 and 2 but improved on day 3. PMID- 27703856 TI - Actin-dependence of the chloroplast cold positioning response in the liverwort Marchantia polymorpha L. AB - The subcellular positioning of chloroplasts can be changed by alterations in the environment such as light and temperature. For example, in leaf mesophyll cells, chloroplasts localize along anticlinal cell walls under high-intensity light, and along periclinal cell walls under low-intensity light. These types of positioning responses are involved in photosynthetic optimization. In light-mediated chloroplast positioning responses, chloroplasts move to the appropriate positions in an actin-dependent manner, although some exceptions also depend on microtubule. Even under low-intensity light, at low temperature (e.g., 5 degrees C), chloroplasts localize along anticlinal cell walls; this phenomenon is termed chloroplast cold positioning. In this study, we analyzed whether chloroplast cold positioning is dependent on actin filaments and/or microtubules in the liverwort Marchantia polymorpha L. When liverwort cells were treated with drugs for the de polymerization of actin filaments, chloroplast cold positioning was completely inhibited. In contrast, chloroplast cold positioning was not affected by treatment with a drug for the de-polymerization of microtubules. These observations indicate the actin-dependence of chloroplast cold positioning in M. polymorpha. Actin filaments during the chloroplast cold positioning response were visualized by using fluorescent probes based on fluorescent proteins in living liverwort cells, and thus, their behavior during the chloroplast cold positioning response was documented. PMID- 27703858 TI - Not always a matter of context: direct effects of red on arousal but context dependent moderations on valence. AB - The arousal theory of color proposes that red is associated with arousal. Research on the color-in-context theory, in turn, states that the context in which red is perceived influences its valence-related meaning and behavioral responses to it. This study faces and integrates these theories by examining the influence of red on both arousal and valence perceptions of test-relevant and neutral stimuli, rendering a color 2 (red vs. blue) * context 2 (test vs. neutral) between-subjects design. Participants rated different pictures regarding their arousal and valence component, respectively. In line with the assumptions of both theories, red increased arousal perceptions of stimuli irrespective of their valence but a context * color interaction was found for valence perceptions: for participants viewing test-relevant pictures, red increased their perceptions of negativity compared to neutral pictures. The present study shows that both theories are actually compatible when differentiating the arousal and valence component. PMID- 27703857 TI - The origin of widespread species in a poor dispersing lineage (diving beetle genus Deronectes). AB - In most lineages, most species have restricted geographic ranges, with only few reaching widespread distributions. How these widespread species reached their current ranges is an intriguing biogeographic and evolutionary question, especially in groups known to be poor dispersers. We reconstructed the biogeographic and temporal origin of the widespread species in a lineage with particularly poor dispersal capabilities, the diving beetle genus Deronectes (Dytiscidae). Most of the ca. 60 described species of Deronectes have narrow ranges in the Mediterranean area, with only four species with widespread European distributions. We sequenced four mitochondrial and two nuclear genes of 297 specimens of 109 different populations covering the entire distribution of the four lineages of Deronectes, including widespread species. Using Bayesian probabilities with an a priori evolutionary rate, we performed (1) a global phylogeny/phylogeography to estimate the relationships of the main lineages within each group and root them, and (2) demographic analyses of the best population coalescent model for each species group, including a reconstruction of the geographical history estimated from the distribution of the sampled localities. We also selected 56 specimens to test for the presence of Wolbachia, a maternally transmitted parasite that can alter the patterns of mtDNA variability. All species of the four studied groups originated in the southern Mediterranean peninsulas and were estimated to be of Pleistocene origin. In three of the four widespread species, the central and northern European populations were nested within those in the northern areas of the Anatolian, Balkan and Iberian peninsulas respectively, suggesting a range expansion at the edge of the southern refugia. In the Mediterranean peninsulas the widespread European species were replaced by vicariant taxa of recent origin. The fourth species (D. moestus) was proven to be a composite of unrecognised lineages with more restricted distributions around the Western and Central Mediterranean. The analysis of Wolbachia showed a high prevalence of infection among Deronectes, especially in the D. aubei group, where all sequenced populations were infected with the only exception of the Cantabrian Mountains, the westernmost area of distribution of the lineage. In this group there was a phylogenetic incongruence between the mitochondrial and the nuclear sequence, although no clear pattern links this discordance to the Wolbachia infection. Our results suggest that, in different glacial cycles, populations that happened to be at the edge of the newly deglaciated areas took advantage of the optimal ecological conditions to expand their ranges to central and northern Europe. Once this favourable ecological window ended populations become isolated, resulting in the presence of closely related but distinct species in the Mediterranean peninsulas. PMID- 27703859 TI - Targeted genomic enrichment and sequencing of CyHV-3 from carp tissues confirms low nucleotide diversity and mixed genotype infections. AB - Koi herpesvirus disease (KHVD) is an emerging disease that causes mass mortality in koi and common carp, Cyprinus carpio L. Its causative agent is Cyprinid herpesvirus 3 (CyHV-3), also known as koi herpesvirus (KHV). Although data on the pathogenesis of this deadly virus is relatively abundant in the literature, still little is known about its genomic diversity and about the molecular mechanisms that lead to such a high virulence. In this context, we developed a new strategy for sequencing full-length CyHV-3 genomes directly from infected fish tissues. Total genomic DNA extracted from carp gill tissue was specifically enriched with CyHV-3 sequences through hybridization to a set of nearly 2 million overlapping probes designed to cover the entire genome length, using KHV-J sequence (GenBank accession number AP008984) as reference. Applied to 7 CyHV-3 specimens from Poland and Indonesia, this targeted genomic enrichment enabled recovery of the full genomes with >99.9% reference coverage. The enrichment rate was directly correlated to the estimated number of viral copies contained in the DNA extracts used for library preparation, which varied between ~5000 and ~2*107. The average sequencing depth was >200 for all samples, thus allowing the search for variants with high confidence. Sequence analyses highlighted a significant proportion of intra-specimen sequence heterogeneity, suggesting the presence of mixed infections in all investigated fish. They also showed that inter-specimen genetic diversity at the genome scale was very low (>99.95% of sequence identity). By enabling full genome comparisons directly from infected fish tissues, this new method will be valuable to trace outbreaks rapidly and at a reasonable cost, and in turn to understand the transmission routes of CyHV-3.

AB - Many migratory bird species show high levels of site fidelity to their wintering sites, which confers advantages due to prior knowledge, but may also limit the ability of the individual to move away from degrading sites or to detect alternative foraging opportunities. Winter site fidelity often varies among age groups, but sexual differences have seldom been recorded in birds. We studied a population of individually colour-marked sanderlings wintering in and around the Tejo estuary, a large estuarine wetland on the western coast of Portugal. For 160 individuals, sighted a total of 1,249 times between November 2009 and March 2013, we calculated the probability that they moved among five distinct wintering sites and how this probability is affected by distance between them. To compare site fidelity among age classes and sexes, as well as within the same winter and over multiple winters, we used a Site Fidelity Index (SFI). Birds were sexed using a discriminant function based on biometrics of a large set of molecularly sexed sanderlings (n = 990). The vast majority of birds were observed at one site only, and the probability of the few detected movements between sites was negatively correlated with the distance among each pair of sites. Hardly any movements were recorded over more than 15 km, suggesting small home ranges. SFI values indicated that juveniles were less site-faithful than adults which may reflect the accumulated knowledge and/or dominance of older animals. Among adults, females were significantly less site faithful than males. A sexual difference in winter site fidelity is unusual in shorebirds. SFI values show site-faithfulness is lower when multiple winters were considered, and most birds seem to chose a wintering site early in the season and use that site throughout the winter. Sanderlings show a very limited tendency to explore alternative wintering options, which might have implications for their survival when facing habitat change or loss (e.g., like severe beach erosion as can be the case at one of the study sites). PMID- 27703861 TI - Feeding bovine milks with low or high IgA levels is associated with altered re establishment of murine intestinal microbiota after antibiotic treatment. AB - Antibiotics are a vital and commonly used therapeutic tool, but their use also results in profound changes in the intestinal microbiota that can, in turn, have significant health consequences. Understanding how the microbiota recovers after antibiotic treatment will help to devise strategies for mitigating the adverse effects of antibiotics. Using a mouse model, we have characterized the changes occurring in the intestinal microbiota immediately after five days exposure to ampicillin, and then at three and fourteen days thereafter. During the fourteen day period of antibiotic recovery, groups of mice were fed either water, cows' milk containing high levels of IgA, or cows' milk containing low levels of IgA as their sole source of liquid. Effects on microbiota of feeding milks for 14 days were also assessed in groups of mice that had no ampicillin exposure. Changes in microbiota were measured by high throughput sequencing of the V4 to V6 variable regions of the 16S ribosomal RNA gene. As expected, exposure to ampicillin led to profound changes to the types and abundance of bacteria present, along with a loss of diversity. At 14 days following antibiotic exposure, mice fed water had recovered microbiota compositions similar to that prior to antibiotics. However, feeding High-IgA milk to mice that has been exposed to antibiotics was associated with altered microbiota compositions, including increased relative abundance of Lactobacillus and Barnesiella compared to the start of the study. Mice exposed to antibiotics then fed Low-IgA milk also showed increased Barnesiella at day 14. Mice without antibiotic perturbation, showed no change in their microbiota after 14 days of milk feeding. Overall, these findings add to a knowledge platform for optimizing intestinal function after treatment with antibiotics in the human population. PMID- 27703862 TI - Reef-scale trends in Florida Acropora spp. abundance and the effects of population enhancement. AB - Since the listing of Acropora palmata and A. cervicornis under the US Endangered Species Act in 2006, increasing investments have been made in propagation of listed corals (primarily A. cervicornis, A. palmata to a much lesser extent) in offshore coral nurseries and outplanting cultured fragments to reef habitats. This investment is superimposed over a spatiotemporal patchwork of ongoing disturbances (especially storms, thermal bleaching, and disease) as well as the potential for natural population recovery. In 2014 and 2015, we repeated broad scale (>50 ha), low precision Acropora spp. censuses (i.e., direct observation by snorkelers documented via handheld GPS) originally conducted in appropriate reef habitats during 2005-2007 to evaluate the trajectory of local populations and the effect of population enhancement. Over the decade-long study, A. palmata showed a cumulative proportional decline of 0.4 -0.7x in colony density across all sites, despite very low levels of outplanting at some sites. A. cervicornis showed similar proportional declines at sites without outplanting. In contrast, sites that received A. cervicornis outplants showed a dramatic increase in density (over 13x). Indeed, change in A. cervicornis colony density was significantly positively correlated with cumulative numbers of outplants across sites. This study documents a substantive reef-scale benefit of Acropora spp. population enhancement in the Florida Keys, when performed at adequate levels, against a backdrop of ongoing population decline. PMID- 27703863 TI - Noise pollution has limited effects on nocturnal vigilance in peahens. AB - Natural environments are increasingly exposed to high levels of noise pollution. Noise pollution can alter the behavior of animals but we know little about its effects on antipredator behavior. We therefore investigated the impact of noise pollution on vigilance behavior and roost selection in an avian species, peafowl (Pavo cristatus), that inhabits urban environments. Captive peahens were exposed to noise pollution at night and their vigilance levels and roost selections were monitored. The vigilance levels of peahens were unaffected by exposure to noise pollution within trials. Furthermore, the peahens exhibited no preference for roosting farther or closer to noise pollution. Interestingly, predators often avoided the experimental area during nights with noise pollution, which could explain why vigilance rates were higher overall during control compared to noise trials. The results suggest that peahens' perception of risk is not drastically impacted by noise pollution but longer-term studies will be necessary to assess any chronic effects. PMID- 27703864 TI - Discovery pattern and species number of scale insects (Hemiptera: Coccoidea). AB - Few investigations have been made of the species description trend of scale insects. The present study reports the discovery pattern and taxonomic efforts for this group based on global species and a literature dataset. In addition, three asymptotic models (Logistic, Gompertz, and Extreme Value) based on a discovery curve were used to predict the species number of scale insects. Our results showed that the species description rate has been changing over time, with certain peaks and valleys in the past 250 years. The mean number of species described per year was 30, with the highest number of 195 described species in 1985. The increasing number of authors and the almost constant proportion of species described by 10% most prolific authors since the 1900s suggested that taxonomic effort has been increasing over time. The Gompertz model with lowest AIC value suggested that there are about 10,450 species of scale insects on Earth, nearly 30% of which remain to be described. Our study offers insights into the discovery pattern of scale insect diversity. PMID- 27703865 TI - Bacterial community diversity of the deep-sea octocoral Paramuricea placomus. AB - Compared to tropical corals, much less is known about deep-sea coral biology and ecology. Although the microbial communities of some deep-sea corals have been described, this is the first study to characterize the bacterial community associated with the deep-sea octocoral, Paramuricea placomus. Samples from five colonies of P. placomus were collected from Baltimore Canyon (379-382 m depth) in the Atlantic Ocean off the east coast of the United States of America. DNA was extracted from the coral samples and 16S rRNA gene amplicons were pyrosequenced using V4-V5 primers. Three samples sequenced deeply (>4,000 sequences each) and were further analyzed. The dominant microbial phylum was Proteobacteria, but other major phyla included Firmicutes and Planctomycetes. A conserved community of bacterial taxa held in common across the three P. placomus colonies was identified, comprising 68-90% of the total bacterial community depending on the coral individual. The bacterial community of P. placomus does not appear to include the genus Endozoicomonas, which has been found previously to be the dominant bacterial associate in several temperate and tropical gorgonians. Inferred functionality suggests the possibility of nitrogen cycling by the core bacterial community. PMID- 27703867 TI - Hierarchical multistate models from population data: an application to parity statuses. AB - Hierarchical models are characterized by having N living states connected by N - 1 rates of transfer. Demographic measures for such models can be calculated directly from counts of the number of persons in each state at two nearby points in time. Exploiting the ability of population stocks to determine the flows in hierarchical models expands the range of demographic analysis. The value of such analyses is illustrated by an application to childbearing, where the states of interest reflect the number of children a woman has born. Using Census data on the distribution of women by age and parity, a parity status life table for US Women, 2005-2010, is constructed. That analysis shows that nearly a quarter of American women are likely to remain childless, with a 0-3 child pattern replacing the 2-4 child pattern of the past. PMID- 27703868 TI - Deer herbivory reduces web-building spider abundance by simplifying forest vegetation structure. AB - Indirect ecological effects are a common feature of ecological systems, arising when one species affects interactions among two or more other species. We examined how browsing by white-tailed deer (Odocoileus virginianus) indirectly affected the abundance and composition of a web-building spider guild through their effects on the structure of the ground and shrub layers of northern hardwood forests. We examined paired plots consisting of deer-free and control plots in the Allegheny Plateau region Pennsylvania and Northern Highlands region of Wisconsin. We recorded the abundance of seven types of webs, each corresponding to a family of web-building spiders. We quantified vegetation structure and habitat suitability for the spiders by computing a web scaffold availability index (WSAI) at 0.5 m and 1.0 m above the ground. At Northern Highlands sites, we recorded prey availability. Spider webs were twice as abundant in deer-free plots compared to control plots, while WSAI was 7-12 times greater in deerfree plots. Prey availability was lower in deer-free plots. With the exception of funnel web-builders, all spider web types were significantly more abundant in deer-free plots. Both deer exclusion and the geographic region of plots were significant predictors of spider community structure. In closed canopy forests with high browsing pressure, the low density of tree saplings and shrubs provides few locations for web-building spiders to anchor webs. Recruitment of these spiders may become coupled with forest disturbance events that increase tree and shrub recruitment. By modifying habitat structure, deer appear to indirectly modify arthropod food web interactions. As deer populations have increased in eastern North America over the past several decades, the effects of deer on web-building spiders may be widespread. PMID- 27703866 TI - Hypernasality associated with basal ganglia dysfunction: evidence from Parkinson's disease and Huntington's disease. AB - BACKGROUND: Although increased nasality can originate from basal ganglia dysfunction, data regarding hypernasality in Parkinson's disease (PD) and Huntington's disease (HD) are very sparse. The aim of the current study was to analyze acoustic and perceptual correlates of velopharyngeal seal closure in 37 PD and 37 HD participants in comparison to 37 healthy control speakers. METHODS: Acoustical analysis was based on sustained phonation of the vowel /i/ and perceptual analysis was based on monologue. Perceptual analysis was performed by 10 raters using The Great Ormond Street Speech Assessment '98. Acoustic parameters related to changes in a 1/3-octave band centered on 1 kHz were proposed to reflect nasality level and behavior through utterance. RESULTS: Perceptual analysis showed the occurrence of mild to moderate hypernasality in 65% of PD, 89% of HD and 22% of control speakers. Based on acoustic analyses, 27% of PD, 54% of HD and 19% of control speakers showed an increased occurrence of hypernasality. In addition, 78% of HD patients demonstrated a high occurrence of intermittent hypernasality. Further results indicated relationships between the acoustic parameter representing fluctuation of nasality and perceptual assessment (r = 0.51, p < 0.001) as well as the Unified Huntington Disease Rating Scale chorea composite subscore (r = 0.42, p = 0.01). CONCLUSIONS: In conclusion the acoustic assessment showed that abnormal nasality was not a common feature of PD, whereas patients with HD manifested intermittent hypernasality associated with chorea. PMID- 27703870 TI - Intravitreal bevacizumab role in the treatment of macular edema secondary to retinal vasoproliferative tumor in a patient with neurofibromatosis type 1. AB - Objective: To report a case of neurofibromatosis-1 (NF-1) with retinal vasoproliferative tumor (RVPT) and macular edema and exudation that was successfully treated with intravitreal bevacizumab (IVB). Method: A retrospective case report of patient with neurofibromatosis, retinal vasoproliferative tumor and macular edema who received three monthly intravitreal injections of bevacizumab. Optical coherence tomography (OCT) and fluorescein angiography (FAG) before and three months after treatment were done. Results: Macular edema and exudation of the right eye was effectively resolved with IVB injection and vascularity of RVPT significantly decreased after treatment with IVB. Conclusion: Macular edema and exudation secondary to RVPT in patients with NF-1 could be successfully treated with IVB. PMID- 27703871 TI - Conjunctival lymphangioma in a 4-year-old girl revealed tuberous sclerosis complex. AB - Background: To present a case of conjunctival lymphangioma in a 4-year-old girl with tuberous sclerosis complex. Methods/results: A 4-year-old girl presented with a relapsing cystic lesion of the bulbar conjunctiva in the right eye with string-of-pearl-like dilation of lymphatic vessels and right-sided facial swelling with mild pain. Best-corrected vision was not impaired. Examination of the skin revealed three hypomelanotic macules and a lumbal Shagreen patch. Magnetic resonance imaging (MRI) findings displayed minimal enhancement of buccal fat on the right side. Cranial and orbital MRI showed signal enhancement in the right cortical and subcortical areas. Genetic analysis revealed a heterozygous deletion encompassing exon 1 and 2 of the TSC1 gene (tuberous sclerosis complex 1 gene), confirming the diagnosis of tuberous sclerosis complex. Conclusion: In conjunctival lymphangioma, tuberous sclerosis complex should be considered as the primary disease. PMID- 27703869 TI - The complete chloroplast genome sequence of Gentiana lawrencei var. farreri (Gentianaceae) and comparative analysis with its congeneric species. AB - BACKGROUND: The chloroplast (cp) genome is useful in plant systematics, genetic diversity analysis, molecular identification and divergence dating. The genus Gentiana contains 362 species, but there are only two valuable complete cp genomes. The purpose of this study is to report the characterization of complete cp genome of G. lawrencei var. farreri, which is endemic to the Qinghai-Tibetan Plateau (QTP). METHODS: Using high throughput sequencing technology, we got the complete nucleotide sequence of the G. lawrencei var. farreri cp genome. The comparison analysis including genome difference and gene divergence was performed with its congeneric species G. straminea. The simple sequence repeats (SSRs) and phylogenetics were studied as well. RESULTS: The cp genome of G. lawrencei var. farreri is a circular molecule of 138,750 bp, containing a pair of 24,653 bp inverted repeats which are separated by small and large single-copy regions of 11,365 and 78,082 bp, respectively. The cp genome contains 130 known genes, including 85 protein coding genes (PCGs), eight ribosomal RNA genes and 37 tRNA genes. Comparative analyses indicated that G. lawrencei var. farreri is 10,241 bp shorter than its congeneric species G. straminea. Four large gaps were detected that are responsible for 85% of the total sequence loss. Further detailed analyses revealed that 10 PCGs were included in the four gaps that encode nine NADH dehydrogenase subunits. The cp gene content, order and orientation are similar to those of its congeneric species, but with some variation among the PCGs. Three genes, ndhB, ndhF and clpP, have high nonsynonymous to synonymous values. There are 34 SSRs in the G. lawrencei var. farreri cp genome, of which 25 are mononucleotide repeats: no dinucleotide repeats were detected. Comparison with the G. straminea cp genome indicated that five SSRs have length polymorphisms and 23 SSRs are species-specific. The phylogenetic analysis of 48 PCGs from 12 Gentianales taxa cp genomes clearly identified three clades, which indicated the potential of cp genomes in phylogenetics. DISCUSSION: The "missing" sequence of G. lawrencei var. farreri mainly consistent of ndh genes which could be dispensable under chilling-stressed conditions in the QTP. The complete cp genome sequence of G. lawrencei var. farreri provides intragenic information that will contribute to genetic and phylogenetic research in the Gentianaceae. PMID- 27703872 TI - Management of implant plate exposure of silicone Ahmed glaucoma valve: a review of six cases. AB - Objective: To describe the management options for exposed silicone Ahmed glaucoma valve (AGV) implant. Methods: This was carried out as a retrospective chart review at a tertiary care eye hospital in Southern India. Medical records of six subjects managed for AGV exposure from 2006 to 2013 were reviewed. Results: All six eyes had explantation of the AGV and 3 of them had reimplantation in a different quadrant at a later date and the other 3 eyes were managed medically. All eyes had well controlled IOP at the last follow-up. The possible predisposing factors for exposure were improper conjunctival coverage, higher number of pre shunt surgeries and diabetes mellitus. Reimplantation was a challenge with scarred conjunctiva and the techniques used were conjunctival advancement, conjunctival relaxing incisions and contralateral conjunctival autograft. None had re-exposure but one eye had conjunctival erosion close to the limbus and was managed with scleral patch graft and conjunctival advancement. Conclusions: Implant exposure is a serious vision threatening complication following glaucoma drainage device implantation. Explantation and timely repair can save these eyes from serious sequel. Reimplantation is a good option, however warrants close follow-up for complications like erosion or re-exposure. PMID- 27703873 TI - Vitrectomy for bilateral macular schisis without apparent optic disc anomalies. AB - A 78-year-old man complained of bilateral visual acuity loss. Optical coherence tomography examination showed bilateral macular schisis with fluid accumulation in the external retinal layers without vitreous traction. Fundus examination and fluorescein angiography were normal in both eyes. Both eyes were treated by phacoemulsification, intraocular lens implantation, and vitrectomy without laser, gas exchange, or retinal fenestration. Slow and progressive fluid resorption and improvement in VA were observed in both eyes. Macular schisis similar to the one associated with optic disc anomalies is a possibility in patients without apparent disc anomalies. Vitrectomy without laser, gas, or retinal fenestration may be a good therapeutic option even in patients with a PVD preoperatively. PMID- 27703874 TI - Avoiding Sand in the Desert. PMID- 27703875 TI - What Counts as High-Quality Practitioner Training in Applied Behavior Analysis? AB - Dixon and colleagues (this issue), who support faculty research productivity as one measure of quality for graduate training programs in applied behavior analysis, show that the faculty members of many programs have limited research track records. I provide some context for their findings by discussing some of the many unanswered questions about the role of research training for ABA practitioners. PMID- 27703876 TI - Research Rankings of Behavior Analytic Graduate Training Programs and Their Faculty. AB - We evaluated research productivity of several graduate programs that provide Behavior Analyst Certification Board (BACB)-approved course sequences in behavior analysis. Considering the faculty of BACB training programs as a unit, in only about 50 %, programs have faculty combined to publish ten or more total articles in our field's primary empirical journals. Among individual faculty members, a sizeable number have not published an article in any of the field's top journals. To recognize major scholarly contributors, we provide top 10 lists of training programs and individual faculty members. We conclude by discussing the importance of research in an increasingly practice-driven marketplace.

AB - The costs for delivering services to individuals with autism and other disabilities total more than $137 billion annually and grow exponentially. Given this figure, service-delivery organizations are under pressure to ensure staff are well-prepared to deliver services through the provision of training. Providing effective staff training and performance management is also necessary for the delivery of evidence-based practice and is an ethical obligation for Behavior Analyst Certification Board(r), Inc. (BACB(r)) certificants. The purpose of the present study was to document the various types of staff and supervisory training and performance management procedures offered to BACB(r) certificants and aspirants working in applied settings.

PMID- 27703879 TI - Global Measures of Treatment Integrity May Mask Important Errors in Discrete Trial Training. PMID- 27703880 TI - Latency-Based FA as Baseline for Subsequent Treatment Evaluation. AB - No research has used latency-based functional analysis (FA) outcomes as baseline data from which to evaluate the effectiveness of subsequent function-based treatments. This approach to analysis calls for the continued collection of latency-based measures for all targeted variables throughout all phases of treatment. We tracked client progress during treatment using latency-based, rate based, and percentage-of-opportunity measures of relevant behavior and compared graphical representations of each. Visual inspection of all data indicates that changes in variability level and trend of latency-based measures correspond well with said changes in more traditional measures. PMID- 27703881 TI - Implications of Derived Rule Following of Roulette Gambling for Clinical Practice. AB - Problem gambling is a global concern, and behavior analytic attention has increasingly focused on reasons for why problem gambling occurs and conditions under which it is maintained. However, limited knowledge currently exists on the process to which self-generated rules maintain gambling behaviors. Therefore, the current study assessed six recreational gamblers on a roulette game before and after discrimination training to establish a self-rule to wager on red or black. Following discrimination training, all six participants altered their response allocation among red or black and consistently responded according to the newly derived self-rule. Results maintained during 1-week follow-up sessions across all participants. Implications for clinical application of self-awareness and self generated rule following are discussed. Implications for practice * Demonstration of how stimuli such as color can alter gambling behavior * Procedures to assist clients with changing self-rules about gambling behavior * Using self-generated rule formulation for more contextually appropriate target behaviors * Highlights how self-generated rules can be altered to change clinical target behaviors. PMID- 27703882 TI - Exploring the Clinical Utility of a Stimulus Avoidance Assessment to Enhance a Relaxation Training Model. AB - The current case study explored the clinical utility of a stimulus avoidance assessment during relaxation training with an adult with an autism spectrum disorder. A multiple stimulus without replacement procedure was implemented with aversive events to identify an aversive situation hierarchy. Aversive events were then systematically presented during the analogue phase of relaxation training across low, medium, and highly aversive events. Results support a clinical utility of using stimulus assessments to inform relaxation training, while suggesting further modifications to relaxation training protocols for generalization of skills. PMID- 27703883 TI - Applied Behavior Analysis and the Autism Diagnostic Observation Schedule (ADOS): a Symbiotic Relationship for Advancements in Services for Individuals with Autism Spectrum Disorders (ASDs). AB - The Autism Diagnostic Observation Schedule (ADOS) is a widely used diagnostic tool for the assessment of autism spectrum disorders. We compared interobserver reliability scores for observers using the existing guidelines for administration of the ADOS with those of the same observers using modified guidelines that included operational definitions for each area of observation. The results indicated increased mean interobserver reliability scores from 55.83 % using the existing guidelines to 84 % when using the modified guidelines and enhanced reliability scores for 3 of 3 clients with whom the ADOS was used. The guidelines are the following: integration of a highly effective diagnostic tool with ABA, the inclusion of a diagnostic tool may promote more comprehensive ABA services, more clearly define and identify areas of concern in autism, and impact implementation efficacy and reliability of assessments for individuals with autism. PMID- 27703884 TI - Effects of a Preferred Stimulus and Mother's Attention on Infant Behavior During Tummy Time. AB - "Tummy time" is an activity for infants to develop muscle tone; however, it often evokes crying and non-compliance. The current study investigated two interventions for an infant to a) increase elevated head behavior, and b) decrease negative vocalizations. The study compared the effects of a preferred stimulus with or without maternal attention on infant behaviors during tummy time. The addition of maternal attention produced more positive outcomes:The science of behavior analysis can be used to treat a broad range of socially significant behaviors like infant behavior during tummy time.Preference assessments can be used with infants to identify potentially reinforcing stimuli.The continuous provision of a preferred stimulus during tummy time may help infants to increase positive behaviors and decrease problem behaviors.Parent attention may have an added benefit to a treatment package for typically developing infants. PMID- 27703885 TI - Maintaining Professional Relationships in an Interdisciplinary Setting: Strategies for Navigating Nonbehavioral Treatment Recommendations for Individuals with Autism. AB - Due to an increase in research and clinical application of behavior analysis with individuals with autism spectrum disorder (ASD), one setting a Board Certified Behavior Analyst (BCBA) may work within is an interdisciplinary setting, where multiple disciplines collaborate to improve the outcomes of individuals with ASD. In some cases, nonbehavioral colleagues could recommend nonbehavioral treatments, setting the occasion for the BCBA to offer an alternative treatment to or question the nonbehavioral treatment. However, excessive questioning or critiques of nonbehavioral treatments by the BCBA may unintentionally erode professional relationships between the BCBA and their nonbehavioral colleagues. Because an erosion of professional relationships may occur when a BCBA questions a nonbehavioral treatment, a decision-making model for determining whether or not the proposed nonbehavioral treatment is worth addressing may be useful. The purpose of this paper is to outline such a decision-making model in order to assist the BCBA in assessing nonbehavioral treatments while maintaining an ethical balance between professional relationships and the well-being and safety of the individual with ASD. Such a model could assist the BCBA in becoming familiar with the proposed treatment, understanding the perspective of the nonbehavioral colleague and assessing the negative impacts the treatment could have on the individual with ASD. With this information, the BCBA will be in a better position to decide whether or not addressing the nonbehavioral treatment is worth the possibility of eroding a professional relationship.

PMID- 27703887 TI - School-wide PBIS: An Example of Applied Behavior Analysis Implemented at a Scale of Social Importance. AB - School-wide Positive Behavioral Interventions and Supports (PBIS) is an example of applied behavior analysis implemented at a scale of social importance. In this paper, PBIS is defined and the contributions of behavior analysis in shaping both the content and implementation of PBIS are reviewed. Specific lessons learned from implementation of PBIS over the past 20 years are summarized. PMID- 27703888 TI - Positive Behavioral Interventions and Support as Behavior Analysis in Practice: Why Is This Even Controversial? AB - The inclusion of Positive Behavioral Intervention and Supports as a type of applied behavior analysis has often spurred considerable controversy. This controversy seems related to at least three areas of contention: measurement issues, views on aversive control, and the overall target of treatment. The present paper discusses these three areas in light of Horner and Sugai's target article and the current state of the field of applied behavior analysis. In the end, the authors are left wondering why this is even an ongoing controversy. PMID- 27703889 TI - School-Wide PBIS: Extending the Impact of Applied Behavior Analysis. Why is This Important to Behavior Analysts? AB - Horner and Sugai (2015) recently wrote a manuscript providing an overview of school-wide positive behavioral interventions and supports (PBIS) and why it is an example of applied behavior analysis at the scale of social importance. This paper will describe why school-wide PBIS is important to behavior analysts, how it helps promote applied behavior analysis in schools and other organizations, and how behavior analysts can use this framework to assist them in the promotion and implementation of applied behavior analysis at both at the school and organizational level, as well as, the classroom and individual level. PMID- 27703890 TI - A Critique of Sociocultural Values in PBIS. AB - Horner and Sugai provide lessons learned from their work with disseminating the Positive Behavioral Interventions and Support (PBIS) model. While PBIS represents an empirical school-wide approach for maladaptive student behaviors, the model appears to have limitations regarding sociocultural values and behavioral data collection practices. The current paper provides an overview of three identified areas for improvement and outlines how administrators using PBIS can incorporate acceptance and mindfulness-based intervention procedures to address the discussed limitations. PMID- 27703891 TI - PBIS Is (Not) Behavior Analysis: a Response to Horner and Sugai (2015). AB - I comment on Horner's and Sugai's article regarding the lessons learned from implementing Positive Behavioral Interventions and Support (PBIS)-that is, the things to consider when attempting to extend other works in behavior analysis to the likes of mainstream society. In adopting a critical eye toward the PBIS model, I comment first on the need for dissemination of behavioral principles to a public audience, and then outline the suggestions made by the authors for enhancing acceptance across disciplines. I clarify the definition of PBIS presented by the authors, and summarize the benefits and drawbacks associated with the conceptual argument surrounding the contention that PBIS is a behavior analytic approach to system-wide change, and argue instead for the distinction of elements in the PBIS model and their respective empirical effectiveness. I refer to other works in behavior analysis that are relevant to the current discussion and offer additional considerations for behavior analysts interested in forging ahead with endeavors that aim increase dissemination, particularly those that incorporate a culmination of alternative professional practices. PMID- 27703892 TI - PBIS May Not Qualify as Classical Applied Behavior Analysis. So What? AB - Some disagreement exists over whether Positive Behavior Interventions and Supports (PBIS) embodies the features of Applied Behavior Analysis (ABA) as described in a classic 1968 paper by Baer, Wolf, and Risley. When it comes to disseminating interventions at a societal level, a more compelling issue is whether ABA should become more like PBIS. PMID- 27703893 TI - Positive Behavior Support for Individuals with Behavior Challenges. AB - Individual positive behavior support (PBS) is a process that combines evidence based practices from applied behavior analysis (ABA) and other disciplines to resolve behavioral challenges and improve independence, participation, and overall quality of life of individuals living and learning in complex community environments. Its features include lifestyle enhancement, collaboration with typical caregivers, tracking progress via meaningful measures, comprehensive function-based interventions, striving for contextual fit, and ensuring buy-in and implementation. This article will summarize the features and illustrate with a case example. * Engaging caregivers to take an active role in behavioral intervention * Designing interventions that work effectively within natural routines * Addressing lifestyle changes, as well as more discrete behavior changes * Creating strategies that are durable, reducing dependence on professionals.

PMID- 27703895 TI - Training Graduate Students to Effectively Disseminate Behavior Analysis and to Counter Misrepresentations. AB - Training graduate students to promote behavior analysis and counter misconceptions requires that graduate programs in behavior analysis contain a healthy dose of experimental analysis of behavior so that students understand the experimental foundations of their discipline. Moreover, graduate students should be required to study the theoretical and philosophical foundations of the field because most of the misconceptions of behavior analysis are conceptual and philosophical in nature. Programs should also teach graduate ABA students to think critically about the concepts and principles of behavior analysis in order to prepare them to defend it against misunderstandings and to be more effective practitioners.

AB - This commentary addresses the two basic premises of the argument made by Dixon et al (2015) concerning quality metrics for behavior analytic graduate training programs. Taken together, these premises assert that the practice of behavior analysis will be more effective if practitioners are research savvy and that becoming research savvy is more likely to occur in a circumstance in which research is ongoing. I support both of these assumptions, the former by examining the impact of group circumstances on values, and the latter by considering the repertorial elements likely to be established under conditions of contingency shaping. PMID- 27703900 TI - In Dreams Begin Responsibility: Why and How to Measure the Quality of Graduate Training in Applied Behavior Analysis. AB - Although no one knows just how effective graduate training may be in creating effective practitioners of applied behavior analysis, there are plenty of logical and historical reasons to think that not all practitioners are equally competent. I detail some of those reasons and explain why practitioner effectiveness may be a more pressing worry now than in the past. Because ineffective practitioners harm the profession, rigorous mechanisms are needed for evaluating graduate training programs in terms of the field effectiveness of their practitioners. Accountability of this nature, while difficult to arrange, would make applied behavior analysis nearly unique among professions, would complement existing quality control processes, and would help to protect the positive reputation and vigorous consumer demand that the profession currently enjoys. PMID- 27703902 TI - Metrics of Quality in Graduate Training. AB - This commentary, in response to Dixon et al. (Behavior Analysis in Practice, 8, 7 15, 2015), describes difficulties in defining metrics of quality in graduate training for different audiences (types of applicants). Outcome measures are preferred whenever possible, supplemented by subjective but frequently used opinion surveys. PMID- 27703903 TI - My Heroes Have Always Been Cowboys. PMID- 27703904 TI - Icing on the Cake: The Role of Research in Practitioner Training. AB - Dixon, Reed, Smith, Belisle, and Jackson (Behavior Analysis in Practice 8, 7-15, 2015) evaluated research productivity in BACB training programs. While research productivity may indeed be an important metric for future researchers, we posit that the field consists mainly of practitioners, and as such training should be focused on practice. We provide an alternative perspective on enhancing the quality of education for behavior analysts who will, by and large, go on to be practitioners. PMID- 27703905 TI - Expanding the Scope of Research Productivity Indices: a Commentary on Dixon, Reed, Smith, Belisle, and Jackson (2015). AB - Dixon et al. (Behavior Analysis in Practice, 8:7-15, 2015) outlined methods to evaluate research rankings of behavior analytic graduate training programs and their graduate faculty. Publications across five behavior analytic journals were evaluated and cumulative totals were obtained for each program and its faculty members. Critchfield (Behavior Analysis in Practice, 8:3-6, 2015) noted that these measures indicated that many graduate students in behavior analysis are receiving training by faculty members with limited research productivity. This commentary offers some suggestions and refinements of the procedures used by Dixon et al. that might provide a more sensitive measure of scholarly productivity in our field. The implications of these suggestions are discussed. PMID- 27703907 TI - The Emperor Just Might Be Wearing Pants. AB - This is a commentary in response to Dixon et al.'s (Behavior Analysis and Practice, 8(1), 7-15, 2015) article entitled, "Research rankings of behavior analytic graduate training programs and their faculty" in Behavior Analysis in Practice. The severe restriction of range for the metric used to identify faculty productivity and knowledge of research calls the implications drawn from the data into question. Suggestions on how to broaden the metric are made along with implications for doing so. This is an important topic, and many people will need to contribute to a robust conversation about our graduate training programs given the exponential growth we have faced in recent decades. PMID- 27703906 TI - Are We Looking for Love in All the Wrong Places? Comment on Dixon et al. AB - Dixon and colleagues (Behavior Analysis in Practice 8(1):7-15, 2015) used publication rates of faculty in programs with Behavior Analyst Certification Board (BACB) approved course sequences as a proxy measure for the quality of the program. The paper is important because it begins a conversation about what the characteristics of a quality program should be. Low publication rates for most of these programs and their faculties were a source of concern for Dixon, et al., but from the perspective of measurement validity, this finding is not necessarily bad news. Program quality is a multi-dimensional construct, and for some dimensions, publication rates are likely to be irrelevant. PMID- 27703908 TI - Evaluating the Quality of Behavior Analytic Practitioner Training Programs. AB - Dixon and colleagues (2015) asserted that faculty research productivity is a key indicator of the quality of university programs that train future practitioners of behavior analysis. Based on their analysis of publications in select journals, the authors concluded that many faculty in such programs have published little to no research. Some alternative measures of both faculty research productivity and the quality of practitioner training programs are suggested here.

We will address points raised in the (Behavior Analysis In Practice 8(1):7-15, 2015) article as well as debate the usefulness of proposed standards of objective ranking. PMID- 27703910 TI - Another Perspective on Research as a Measure of High-Quality Practitioner Training: a Response to Dixon, Reed, Smith, Belisle, and Jackson. AB - Dixon et al. (Behavior Analysis in Practice 8:7-15, 2015) argued that the research productivity of behavior analytic graduate programs may be a reasonable criterion to evaluate training program quality. They reviewed the cumulative publications of graduate programs. From this analysis, they generated a top ten list of graduate programs with the greatest number of faculty publications and, because of the number of these publications, inferred that they may be better training programs than those not on the list. We countered that the quality of graduate training programs is evident in the behavior of those who are trained, and thus, our field's interest should focus on determining the degree to which individual program graduates-and not their faculty-have mastered the research process. Thus, we proposed including student authors' work as an alternative to Dixon et al.'s analysis. PMID- 27703912 TI - An Alternative Strategy for Selecting a Graduate Program: Comments on Dixon et al. (2015). AB - While the rankings based upon frequencies of publication, supplied by Dixon et al. (2015), identify individuals and programs worthy of prospective students' attention, I have focused upon other criteria when mentoring students who are deciding where to apply for graduate study. Those criteria concern the student's particular interests, and questions concerning what it is like to work with a given mentor or within a given program. Besides perusals of web sites and queries directed to prospective mentors, students already working with that mentor can provide valuable information. Provision for hands-on training in the application of behavioral principles is essential to a high-quality program, and availability of conceptually oriented courses and of a supportive verbal community are additional considerations, especially if a mentor is not frequently available for informal conversation. As alternatives, the Behavior Analysis Certification Board's credential has the limitations of any multiple-choice examination as an evaluation of hands-on competence, and the accreditation of programs by the Association for Behavior Analysis International omits many mentorships that have trained outstanding behavior analysts via "apprenticeships" within programs that are not primarily behavior analytic.

Several commentaries followed the release of our article, with content that ranged from supporting our endeavors and confirming the dangerous position our field may be in to highlighting the need for further refinement in procedures used to rank the quality of behavior analysis graduate training programs.

AB - While the use of computer-based communication, video recordings, and other "electronic" records is commonplace in clinical service settings and research, management of digital records can become a great burden from both practical and regulatory perspectives. Three types of challenges commonly present themselves: regulatory requirements; storage, transmission, and access; and analysis for clinical and research decision-making. Unfortunately, few practitioners and organizations are well enough informed to set necessary policies and procedures in an effective, comprehensive manner. The three challenges are addressed using a demonstrative example of policies and procedural guidelines from an applied perspective, maintaining the unique emphasis behavior analysts place upon quantitative analysis. Specifically, we provide a brief review of federal requirements relevant to the use of video and electronic records in the USA; non jargon pragmatic solutions to managing and storing video and electronic records; and last, specific methodologies to facilitate extraction of quantitative information in a cost-effective manner.

AB - Pediatric feeding disorders are common among children with developmental disabilities and can have detrimental effects on growth and development. An escape extinction and negative reinforcement-based approach to treating food refusal was examined in a child with cerebral palsy. A changing criterion treatment design was implemented, which allowed the child to exit the treatment area contingent upon the acceptance and ingestion of a pre-determined number of bites. Food acceptance ranged from one to three bites at baseline and exceeded the pre-set criteria for mastery, at 14 bites during the final intervention phase.The study will contribute to the current literature on negative reinforcement procedures used in the treatment of pediatric feeding problems.The study will contribute to increasing the availability of literature pertaining to pediatric feeding problems among children with complex disabilities such as cerebral palsy.The intervention is brief with components to the treatment package which increases utility and ease of implementation.The study demonstrates the applicability of changing criterion design within clinical settings.

A task analysis (TA) and forward chaining were combined with a stimulus fading procedure to allow the subject to be able to participate in van rides when prompted with no displays of aggressive or self-injurious behavior. A follow-up probe completed at 1-year post intervention demonstrated the maintenance of the gains that were made during treatment.

AB - Automatic reinforcement by response-produced auditory stimuli has long been hypothesized to play a role in the vocal development of infants. Clinicians and researchers have translated this idea into stimulus pairing interventions intended to increase novel vocalizations of nonverbal children with autism and other developmental disabilities by conditioning speech sounds as reinforcers. A number of studies have demonstrated positive effects of stimulus pairing procedures, but negative results have also been reported in the literature. This article provides a brief review of the existing literature on stimulus pairing procedures and a discussion of alternative procedures that may serve to establish speech sounds as reinforcers. Directions for future research are discussed and recommendations provided to clinicians.

Videoconferencing programs like SkypeTM represent one avenue for remote supervision. The current study compares the effects of covert observations, in vivo observations, and observations using the SkypeTM program on treatment integrity in three therapists working with children diagnosed with autism. The results show that the level of treatment integrity is comparable in both the in vivo and SkypeTM conditions, both of which are superior to the covert observation condition. PMID- 27703925 TI - Using Graduated Exposure and Differential Reinforcement to Increase Food Repertoire in a Child with Autism. AB - Food selectivity is often seen in children with autism spectrum disorder and can lead to severe nutritional deficiencies. Food selectivity can be specific to food texture, colour, shape, presentation, type, brand or container. Often food selectivity is treated using escape extinction in conjunction with other procedures, which can be challenging to implement for the therapist or caregiver, aversive for the child, and requires adequate supervision from a professional to ensure fidelity of the procedure. A preference assessment, parent interview and food journal determined the child's food repertoire consisted of four different foods in total (pasta, fish crackers, dry cereal and yogurt), and the child was selective by brand, texture, temperature and utensil requirement. A 12-step graduated exposure food hierarchy was constructed, the child was lead through the hierarchy, and parent training was implemented for generalization. After 9 months of treatment, the participant's food repertoire increased from four items to more than 50 items. Additionally, food refusal behaviour decreased to rates of zero during intervention and parents report significant decreases in mealtime behaviour at home. The importance of using an alternative strategy to escape extinction for treating food selectivity in children with autism spectrum disorder will be discussed.

AB - The present study evaluated the effectiveness of five packaged protocols from the Promoting the Emergence of Advanced Knowledge (PEAK) curriculum. The skills targeted in the study included complex verbal operants proposed by Skinner (Verbal behavior. Englewood Cliffs, NJ: Prentice Hall, 1957), an area that is lacking in the current literature. The target skills included autoclitics, metonymical tacts, tacting planet names, and guessing. The results suggest that the PEAK methodology was effective in teaching each of the targeted skills to a mastery criterion, as well as maintenance of those skills at a 2-week follow-up phase. PMID- 27703928 TI - Infected shoulder joint with loose Suture Anchor in the joint after Bankart's Repair- A Case Report. AB - INTRODUCTION: The glenoid labrum is frequently torn in traumatic glenohumeral dislocation; arthroscopic repair is the standard method of treatment. The complications associated with this repair are pulling out of metal suture anchors, chondrolysis and joint infection. The infection of joint after arthroscopy is less than 1%. Staphylococcus is most common organism and rarely followed by Pseudomonas aeruginosa. We report a case of infected shoulder with chondrolysis of the joint and pulled out metal suture anchor lying inside the joint after Bankart's repair. CASE REPORT: A 22-year-old gentleman came to us with complaints of shoulder joint pain & gross restriction of movements for one year, with history of intermittent fever and treatment in nearby hospital. He also gives past history of recurrent dislocation of shoulder with last episode 18 months back, which was diagnosed as Bankart's lesion and arthroscopic Bankart's repair was done 15 months back. He was evaluated at our institute and suspected to have infection of shoulder joint with pulled out metal suture anchor inside the joint. Arthroscopic removal of suture anchor and debridement of shoulder joint was done, Culture was obtained and culture specific antibiotics were given for six weeks, and significant improvement was observed with this line of treatment. At lyear follow up, the patient was able to perform his daily activities with terminal restriction of range of motion. CONCLUSIONS: Shoulder joint infection is rare after Bankart's repair and required a high degree of suspicion. Any foreign materials inside the joint should be taken out & followed with aggressive treatment by debridement, irrigation and culture specific antibiotics. Suppression of joint infection with antibiotics should be avoided specially when there is foreign body inside the joint. PMID- 27703929 TI - Dedifferentiated Chondrosarcoma of Proximal Tibia and Fibula with an Infected Ulcer: A Case Report. AB - INTRODUCTION: Dedifferentiated chondrosarcoma (DDCS) is a rare and malignant form of primary bone tumor refractive to chemotherapy and radiotherapy. It accounts for 1-2% of all primary bone tumors. Surgical resection, limb-salvage surgeries and amputation remain the mainstay of treatment. The prognosis of dedifferentiated chondrosarcoma is poor. CASE REPORT: We report a case of a 51 year-old male having a swelling and an ulcer distal to the left knee later diagnosed with dedifferentiated chondrosarcoma of proximal tibial and fibular metaphysis. Although DDCS is a highly malignant tumor, no metastasis was found and the patient was treated with transfemoral amputation. Post-operative histopathology showed nuclear atypia, binucleated and multinucleated chondrocytes with spindling and neoplastic cells arranged in storiform pattern and giant cells which confirmed the diagnosis of DDCS. CONCLUSION: Early diagnoses and treatment are important while treating these tumors in order to prevent morbidity and mortality. PMID- 27703927 TI - Genome-Wide Anaplasma phagocytophilum AnkA-DNA Interactions Are Enriched in Intergenic Regions and Gene Promoters and Correlate with Infection-Induced Differential Gene Expression. AB - Anaplasma phagocytophilum, an obligate intracellular prokaryote, infects neutrophils, and alters cardinal functions via reprogrammed transcription. Large contiguous regions of neutrophil chromosomes are differentially expressed during infection. Secreted A. phagocytophilum effector AnkA transits into the neutrophil or granulocyte nucleus to complex with DNA in heterochromatin across all chromosomes. AnkA binds to gene promoters to dampen cis-transcription and also has features of matrix attachment region (MAR)-binding proteins that regulate three-dimensional chromatin architecture and coordinate transcriptional programs encoded in topologically-associated chromatin domains. We hypothesize that identification of additional AnkA binding sites will better delineate how A. phagocytophilum infection results in reprogramming of the neutrophil genome. Using AnkA-binding ChIP-seq, we showed that AnkA binds broadly throughout all chromosomes in a reproducible pattern, especially at: (i) intergenic regions predicted to be MARs; (ii) within predicted lamina-associated domains; and (iii) at promoters <= 3000 bp upstream of transcriptional start sites. These findings provide genome-wide support for AnkA as a regulator of cis-gene transcription. Moreover, the dominant mark of AnkA in distal intergenic regions known to be AT enriched, coupled with frequent enrichment in the nuclear lamina, provides strong support for its role as a MAR-binding protein and genome "re-organizer." AnkA must be considered a prime candidate to promote neutrophil reprogramming and subsequent functional changes that belie improved microbial fitness and pathogenicity. PMID- 27703930 TI - Case Report of Two Cases of Patella Subacute Osteomyelitis in Diabetic Women A Rare Entity. AB - INTRODUCTION: Patella osteomyelitis is a rare entity in adults. Most often it is seen in children of five to twelve years of age because of its unique ossification and vascularity. Immuno compromised states like HIV, tuberculosis, intravenous drug abuse and trauma have been predisposing factors for adult patellar osteomyelitis. We report two cases of patellar osteomyelitis in adult diabetic women with uncontrolled glycemic levels and having no previous history of any trauma or systemic infection. CASE REPORT: A 43-year-old diabetic woman presented with complaints of left knee pain and swelling with no history of trauma. On examination, pointed tenderness was present over anterior aspect of patella with patellar grind test positive. Radiography and MRI revealed solitary well circumscribed patellar cyst. Lateral chondral blisters were noted while doing arthroscopy and secretions oozed out on puncturing. Curettage was carried out for the same. Culture and sensitivity revealed no growth and the patient was prescribed antibiotics for 6 weeks. Second case was a 46-year-old diabetic lady with similar presentation. MRI additionally showed abscess in intermuscular plains around knee joint. An aspirated fluid was negative for growth of organisms. Knee arthrotomy and curettage of patellar sinus tracts was done with evacuation of intramuscular abscess. Antibiotics were given for 6 weeks. Both patients had complete relief of symptoms. CONCLUSION: Patella osteomyelitis in adults is very rare. In patients with uncontrolled diabetes, vague anterior knee pain, elevated ESR and CRP, one should keep patellar subacute osteomyelitis as a differential diagnosis which can be further confirmed by X-ray, MRI or bone scan. An appropriate early treatment with antibiotics and surgical intervention can give a satisfactory result. PMID- 27703931 TI - Retrocalcaneal Bursitis due to Rare Calcaneal Osteochondroma in Adult Male : Excision and Outcome. AB - INTRODUCTION: Osteochondroma is the most common benign tumour of the bone and is considered as developmental lesion of the bone. Common site of osteochondroma presentation is around the knee but calcaneal osteochondroma as such is a rare entity. Osteochondromas grow during childhood through adolescence, but usually the growth of osteochondroma ends when the epiphyseal plates close. In an adult, growth of an osteochondroma suggests the diagnosis of a malignant transformation. However, it can also present as pressure symptom in later phase of life. Here, we presented a case of retrocalcaneal bursitis in late phase of life of a male farmer due to late growth of osteochondroma. CASE PRESENTATION: We report a case of calcaneal osteochondroma which is an extremely rare site of occurrence with painful swelling of ankle causing limitation of walking in a 58-year-old male. Surgical excision of tumour followed by a histological confirmation reported negative for any malignant changes. CONCLUSION: There may be chances of osteochondroma being a reason for retrocalcaneal bursitis. It is possible of late detection of benign osteochondromas which show symptomatic growth and pressure effect in skeletally mature patients without malignant transformation. PMID- 27703932 TI - Acromioclavicular Joint Dislocation with Ipsilateral Mid Third Clavicle, Mid Shaft Humerus and Coracoid Process Fracture - A Case Report. AB - INTRODUCTION: The clavicle, humerus and acromioclavicular (AC) joint separately are very commonly involved in traumatic injuries around the shoulder. Acromioclavicular joint dislocation with distal clavicle fracture is a well recognized entity in clinical practice. AC joint dislocation with mid shaft clavicle fracture is uncommon and only few cases have been reported in literature. However, to the best of our knowledge, this is the first case report to describe an acromioclavicular dislocation with ipsilateral mid shaft clavicle, mid shaft humerus and coracoid process fracture. Fractures of the humerus and clavicle along with the acromioclavicular joint dislocation were fixed at the same setting. CASE REPORT: A 65-year-old male met with a high velocity road traffic accident. Plain radiographs showed displaced mid third clavicle fracture with acromioclavicular joint dislocation with mid shaft humerus fracture. Surgical fixation was planned for humerus with interlocking nail, clavicle with locking plate and acromioclavicular joint with reconstruction of coracoclavicular ligaments. Intraoperatively, coracoid process was found to have a comminuted fracture. The operative plan had to be changed on table as coracoclavicular fixation was not possible. So acromioclavicular joint fixation was done using tension band wiring and the coracoclavicular ligament was repaired using a 2-0 ethibond. The comminuted coracoid fracture was managed conservatively. K wires were removed at 6 weeks. Early mobilization was started. CONCLUSION: In acromioclavicular joint injuries, clavicle must be evaluated for any injury. Although it is more commonly associated with distal clavicle fractures, it can be associated with middle third clavicle fractures. As plain radiographs, AP view are most of the times insufficient for viewing integrity of coracoid process, either special views like Stryker notch or CT scan may help in diagnosing such concealed injuries. When associated with fractures of the humerus and clavicle, anatomical restoration of acromioclavicular joint along with anatomical reduction and a rigid fixation of associated fractures is essential. Proper rehabilitation protocol is a must for achieving promising results. In our case, we were able to achieve a stable surgical fixation of both the fractures as well as AC joint, which enabled us to start early joint mobilization and rehabilitation.

AB - INTRODUCTION: Arthroscopic fixation of tibial spine fracture without damage to the growth plate is very important in patients with open physis. The present article describes a simple and effective technique being used for the first time to treat this condition. CASE REPORT: A 16-year-old boy sustained avulsion fractures of tibial spine while playing. He was treated arthroscopically with excellent result. CONCLUSION: Arthroscopic fixation of tibial spine fracture in patients with open physis with two cannulated screws perpendicular to each other is a very simple technique which provides strong construct, and allows early mobilization without risk of damage to the growth plate. PMID- 27703934 TI - A Case of Septic Arthritis of Shoulder Presenting as Stiffness of the Shoulder. AB - INTRODUCTION: Septic arthritis of the shoulder is uncommon in adults. It is a surgical emergency as joint destruction occurs rapidly and can lead to significant morbidity and mortality. Accurate diagnosis can be particularly challenging in patients with underlying liver disease. MRI is a useful adjunct in early detection of atypical causes of shoulder pain. CASE REPORT: A 43 years old male came to our outpatient department with complaints of pain and stiffness of his left shoulder. On examination, his shoulder movements were severely restricted. Further evaluation with MRI revealed septic arthritis of left gleno humeral joint for which emergency arthroscopic debridement was done. CONCLUSION: Septic arthritis of shoulder may not present with classical clinical features. Hence, a through clinical and radiological evaluation will help us prognosticate and treat accordingly thereby preventing complications like septic shock, osteomyelitis.

AB - INTRODUCTION: A Jehovah's Witness belongs to the religious group that does not accept blood transfusion in any form, while a sickle cell disease patient has abnormal haemoglobins that do not last in circulation predisposing one to anaemia and other systemic complications. Performing a major surgery in a Jehovah's Witness who has sickle cell disease is tasking for a surgeon. CASE PRESENTATION: This case reports a 28-year-old African female with sickle cell disease who outrightly refused any form of blood transfusion as being a Jehovah's Witness and having a complex primary hip that required total hip replacement. This work highlighted the complexity and difficulty encountered by virtue of the fact that patient had orthopaedic complications of Sickle Cell Disease and measures taken to prevent sickling crisis. CONCLUSION: It is possible to carry out major surgery in a sickler who has durable power of attorney not to receive blood, but optimum preparation, meticulous and fast surgery and adequate monitoring must be instituted to avert morbidity and mortality seen in this group of patients. PMID- 27703936 TI - Short stature Revealing a Pycnodysostosis: A Case Report. AB - INTRODUCTION: Pycnodysostosis is a rare genetic disease characterized by osteosclerosis and bone fragility. The clinical aspects are varied including short stature, acro-osteolysis of distal phalanges, and dysplasia of the clavicles. Oral and maxillofacial manifestations of this disease are very clear. The head is usually large, a beaked nose, obtuse mandibular angle, and both maxilla and mandible are hypoplastic. Dental abnormalities are common. We report a case with the typical clinical and radiological characteristics of the Pycnodysostosis associated with a conductive hearing loss, an association rarely reported. CASE PRESENTATION: A 12-year-female was admitted in our institute for short stature with a dysmorphic facies for evaluation. The patient reported a history of multiple fractures of the long bones after a trivial fall. On physical examination, she had the following features: short stature, limited mouth opening, short hands and feet with dysplastic nails; frontal and occipital bossing; and hypoplasia of the maxilla and mandible. Examination of the mouth: grooved palate, caries of the teeth, impacted and malposed teeth, persistent deciduous teeth and missing teeth. Laboratory investigations were normal. The radiographic examination showed a generalized increase in the bone density, slight condensation of the skull base and a very open mandibular angle. X-rays showed tapered phalanges with acro-osteolysis of the distal phalanges. A symptomatic treatment was proposed based on fracture prevention, oral hygiene, frequent dental visits and psychiatric support. CONCLUSION: The clinical and radiological features are the bases for the diagnosis of this disease. It is important to make the diagnosis as early as possible in order to plan the treatment and to provide a better life quality to the patients. PMID- 27703937 TI - Mega Prosthetic Replacement of Elbow for Resistant Nonunion of Distal Humerus. AB - INTRODUCTION: Fractures of the distal humerus are a rare entity accounting for approximately 2% of the humeral fractures. Non union of the distal humerus is further rare and poses a major challenge. These fractures usually respond to open reduction and bone grafting but some may fail multiple surgical attempts at union and hence are labelled as "resistant" non union. We report a case of resistant non union of the distal humerus which was managed by total elbow arthroplasty. CASE PRESENTATION: A 49-year-old male presented to the out patient department with history of a compound comminuted fracture of the distal end of the humerus approximately 25 years back. The fracture was treated with multiple debridements and plaster cast application. There was involvement of the radial and the ulnar nerves as well. The patient continued to use the disabled upper limb with severe difficulties in activities of daily living (ADL). The patient finally presented to us for regaining some range of motion and improvement in his ADL. In view of the grossly distorted anatomy, bone loss and chronic nature of the problem, patient was offered total elbow arthroplasty. The Wadsworth extensile posterior approach was used for exposure of the non union site. The fragments were found to be small, osteoporotic and deformed. In view of the distorted anatomy, the elbow was finally salvaged with mega-prosthetic replacement of the elbow. Posterior elbow splint was used for 2 weeks and active as well as passive range of motion was started after that. The post-operative Mayo elbow score improved from 50 to 80 and the patient was able to achieve a range of motion from 10 degrees to 110 degrees. CONCLUSION: Total elbow arthroplasty can be used as a salvage procedure for resistant non union of the elbow with failed multiple failed attempts at union. It can also be used as a definitive procedure for severely distorted non union with massive bone loss with satisfactory functional results. PMID- 27703938 TI - Novel Presentation of Uncommon Wrist Injury: Simultaneous Lunate and Perilunate Fracture Dislocation (scapho-capitate Syndrome) of Both Wrists. AB - INTRODUCTION: Perilunate and lunate dislocations are uncommon high energy injuries and have extensive soft tissue, cartilaginous and bony damage. The most common pattern is trans-scaphoid perilunate fracture dislocation which constitutes approximately 50% of these injuries. Unusual injury pattern like Scaphocapitate syndrome can occur with fracture through scaphoid waist and capitate that rotates the proximal capitate 180 degrees so that its proximal articular surface points distally. With this case report, we would like to present a novel presentation of an uncommon wrist injury. CASE REPORT: We present a case of simultaneous lunate dislocation in one wrist and perilunate fracture dislocation (Scapho- capitate syndrome) in the contralateral wrist which occurred simultaneously in a young male following a two wheeler accident. The injury was missed initially at the primary treating centre. Upon diagnosis, the patient underwent open reduction and internal fixation along with ligament repair. The patient was subsequently followed up for a period of four years and was found to have very good clinical and radiological outcome. CONCLUSION: These injuries occurring simultaneously in contralateral wrists are exceptionally rare and unusual as the mechanisms of injury are different. These are high velocity injuries and are often missed, especially in presence of other major injuries. These high energy injuries need accurate diagnosis, early and aggressive treatment in order to prevent complications. PMID- 27703939 TI - BBilateral Neglected Anterior Shoulder Dislocation with Greater Tuberosity Fractures. AB - INTRODUCTION: Shoulder dislocations are a very common entity in routine orthopaedic practice. Chronic unreduced anterior dislocations of the shoulder are not very common. Neurological and vascular complications may occur as a result of an acute anterior dislocation of the shoulder or after a while in chronic unreduced shoulder dislocation. Open reduction is indicated for most chronic shoulder dislocations. We report a case of neglected bilateral anterior shoulder dislocation with bilateral displaced greater tuberosity fracture. To the best of our knowledge, only a handful cases have been reported in literature with bilateral anterior shoulder dislocation with bilateral fractures. Delayed diagnosis/reporting is a scenario which makes the list even slimmer and management all the more challenging. CASE REPORT: We report a case of a 35-year old male who had bilateral anterior shoulder dislocation and bilateral greater tuberosity fracture post seizure and failed to report it for a period of 30 days. One side was managed conservatively with closed reduction and immobilization and the other side with open reduction. No neurovascular complications pre or post reduction of shoulder were seen. CONCLUSION: Shoulder dislocations should always be suspected post seizures and if found should be treated promptly. Treatment becomes difficult for any shoulder dislocation that goes untreated for considerable period of time.

AB - INTRODUCTION: Chronic osteomyelitis is a disease that requires fastidious treatment to eliminate. However, when eradication is unable to be achieved through exhaustive modalities of antibiotic therapy and multiple debridements, significant resection of the infected bone and soft tissue must be considered, including amputation. Here we report of a salvage procedure for chronic osteomyelitis of the left tibia by employing a rotationplasty to avoid an above knee amputation and instead provide the patient with a below knee amputation. CASE REPORT: A 51-year-old male presented to the emergency department after noticing dehiscence of an operative wound with exposure of an implant in the left lower extremity. Two years prior to presentation, the patient was involved in a motorcycle accident and underwent four surgeries in the Dominican Republic for an open fracture of the left tibia and fibula, including a procedure that involved the placement of an implant in the left proximal tibia. Tissue biopsies from the wound confirmed that the patient had osteomyelitis of the left proximal tibia. After extensive surgical and antibiotic intervention to eradicate the patient's osteomyeltis, it was eventually determined that an amputation would be necessary. In order to avoid an above knee amputation, a salvage procedure was conducted by employing a rotationplasty to provide the patient with a below knee amputation. CONCLUSION: When amputation is deemed necessary, sparing the knee joint is associated with decreased energy expenditures, increased patient satisfaction and overall better postoperative outcomes. As part of a multi-disciplinary team, orthopaedics, plastic surgery, infectious disease, and medical services successfully treated this case of chronic osteomyelitis of the left proximal tibia by employing a rotationplasty to avoid an above knee amputation and achieve a below knee amputation. PMID- 27703941 TI - Schwannoma of the Median Nerve at Mid Forearm Level. AB - INTRODUCTION: Schwannomas are also known as neurilemmoma that usually originate from Schwann cells located in the peripheral nerve sheaths. It usually occurs in the age group of 20 to 70 years. These are the commonest tumors of the peripheral nerves, 5% of which occur in the adults and 19% of the tumors occur in upper extremities. Schwannomas are generally presented as an asymptomatic mass. Discomfort may be the only presenting complaint of the patient. Paresthesia may be elicited on tapping the swelling. Magnetic resonanceimaging, and ultrasound are helpful in the diagnosis. Surgical removal is usually curative. CASE PRESENTATION: A 28-year-old male came to our hospital for a lump located at the volar side of the right mid forearm for 10 years with discomfort and paresthesia in median nerve distribution of hand which appeared in last two years. Total excision was performed for the lesion. Histopathological examination of the mass revealed typical features of schwannoma. At two months follow-up, the patient was symptom free with mild paresthesia in his index and middle fingers. CONCLUSION: Benign tumours involving peripheral nerves of the upper extremity are uncommon. Schwannomas are theoretically removable because they repulse fascicular groups without penetrating them, thus allowing their enucleation while preserving nerve continuity, as reported in our patient. PMID- 27703942 TI - Bilateral Spontaneous Midsubstance Patellar Tendon Rupture after Bilateral Total Knee Arthroplasty. AB - INTRODUCTION: Patellar tendon rupture can occur due to multiple causes ranging from inflammatory pathologies to episodes of trauma. Extensor mechanism rupture is a rare complication of total knee arthroplasty (TKA). In most of these cases, the failure occurs as avulsion of patellar tendon from tibial tuberosity. We report a rare case with bilateral mid-substance patellar tendon rupture one month after bilateral total knee arthroplasty. CASE PRESENTATION: A 69-year-old male was operated for bilateral grade 4 osteoarthritis. On day 30 post-operative, he sustained bilateral patellar tendon rupture while getting up from toilet. He had a history of multiple steroid injections in the knee, which could have affected the tendon. The other etiologies could be inherent weakness of tendon due to diabetes and old age and micro-trauma/stretch associated with sudden correction of previous deformity by TKA. The management in our case was done by primary repair along with augmentation by autologous semitendinosus graft and suture anchor. CONCLUSION: The operating surgeon must be aware of the possibility of patellar tendon rupture following total knee arthroplasty. This will help the surgeon in early recognition and preparedness to handle such complications, should they arise. Surgeons may consider advising caution to both patient and rehabilitation team in cases with old age, chronic diabetes mellitus, and with a history of steroid injections. PMID- 27703943 TI - Slipped Distal Femoral Epiphysis in Congenital Insensitivity to Pain. AB - INTRODUCTION: Congenital insensitivity to pain (CIP) is a rare disorder, and often presents to an orthopaedic surgeon as recurrent fractures, dislocations, pseudoarthrosis, osteomyelitis etc. Here, we report a case of congenital insensitivity to pain presenting with distal femoral physeal separation in a child. CASE REPORT: A 12-year-old girl child came with complaints of limp while walking and swelling in the left knee for past 5 weeks. Mother gave a history that the girl is a known case of congenital insensitivity to pain with clear history of no pain on intramuscular injection since birth. She was born of consanguineous marriage and had no significant trauma, fever, other joint involvement or any features of rheumatism. On local examination, she had no bony tenderness, mild warmth, and moderate knee effusion with restricted range of movement. Plain radiograph showed epiphysiolysis of distal femur with widening of physis. Examination under anaesthesia demonstrated gross movement indicating lower femoral physeal separation. This unstable distal femoral epiphysis was treated under general anaesthesia with closed reduction, percutaneous cross pinning and above knee plaster cast. CONCLUSION: Congenital insensitivity to pain (CIP) is a rare disorder to diagnose. Emphasis is given on early diagnosis of orthopaedic problems and prompt treatment, educating parents and prevention of accidents. Physeal separation without significant trauma must prompt an orthopaedic surgeon to think about congenital insensitivity to pain as a differential diagnosis. PMID- 27703944 TI - Intraosseous Leiomyoma of the Tibia. A Case Report. AB - INTRODUCTION: Leiomyoma is benign smooth-muscle tumor most commonly arising in the uterus, the gastrointestinal tract, and the skin. Leiomyomata are infrequently seen in the extremities and rarely seen in the bone. It is usually presented by a gradually increasing pain with nonspecific radiological findings, and could be a differential diagnosis for wide range of bone tumors. CASE PRESENTATION: We report a case of a 73-year-old Japanese female patient with a painful intraosseous leiomyoma involving the proximal tibia. The patient had undergone tumor excision with wide margin, immediate weight bearing was allowed, pain had been relieved and the patient was satisfied with no recurrence, malignant change, distant metastases or functional impairment. We reviewed all published cases of intraosseous leiomyomata in English literature. CONCLUSION: Diagnosis of Intraosseous leiomyoma of the extremities is difficult due to extreme rarity of the tumor and absence of pathognomonic radiological sign in X ray, CAT, or even MRI. While the exact diagnosis is only achieved by histopathological examination and with immunohistochemistry stains, which can differentiate it from malignancy, especially from the much less rare leiomyosarcoma. Orthopedic oncologists have to include this rare benign tumor in the differential diagnosis of any intraosseous lesion with gradually worsening and long-standing pain, despite of benign imaging characters. Different histological patterns of leiomyoma do exist, however there is no difference in prognosis or treatment options. Treatment standard includes wide excision with autologous bone graft whenever possible. Internal fixation may be necessary if the bone defect is large or there is thinning out of the cortex that may lead to pathological fracture. PMID- 27703945 TI - Arthroscopic Fixation of Tibial Spine Avulsion Fracture in Open Physis. AB - INTRODUCTION: Arthroscopic fixation of tibial spine fracture in patients with open physis without damaging the growth plate is very important. We have described a very simple and effective technique for the first time in this article. CASE REPORT: A 16-year-old boy sustained avulsion fractures of tibial spine while playing. He was treated arthroscopically with excellent results. CONCLUSION: Arthroscopic fixation of tibial spine fracture in patients with open physis with two cannulated screws perpendicular to each other is a very simple technique providing strong construct, and allowing early mobilization without risk of damage to the growth plate. PMID- 27703946 TI - Open Periprosthetic Patellar Fracture after Total Knee Replacement. AB - INTRODUCTION: Periprosthetic patellar fracture after total knee arthroplasty (TKA) is a rare complication. Their management can be very challenging with unpredictable results. Literature analysis showed few articles about this complication, but no publication has described the management of open patella fracture around total knee arthroplasty. CASE PRESENTATION: We report a unique case of an open patellar fracture above a total knee arthroplasty, sustained by a 56-year-old female patient. CONCLUSION: Despite the poor outcome of operative management in patellar periprosthetic fracture, this approach should be considered for acute and post traumatic fractures in young patients with a good remaining bone stock. PMID- 27703947 TI - Erythromycin Seromadesis in Orthopedic Surgery. AB - INTRODUCTION: The presence of postoperative seromadesis is common, corresponding to the presence of serum in the subcutaneous tissue post a surgical event. Erythromycin has been reported as sclerosing, although not in orthopedic surgery. We report a case of erythromycin seromadesis in orthopedic surgery. CASE PRESENTATION: We present a case of a 63-year-old woman having undergone femoral prosthesis surgery and total hip replacement with a subfacial seroma without findings of infection, refractory to standard treatment of compression bandages, massage and cleaning surgery in two oportunities. A literature review was undertaken to obtain the therapeutic alternatives where erythromycin seromadesis is chosen with excellent response. CONCLUSION: Erythromycin sclerotherapy should be considered as an effective and safe option in the treatment of seroma in general surgery and traumatology. More studies are necessary to get a better evidence. We believe that this is the first study of use of erythromycin as sclerotherapy in a traumatology case. PMID- 27703948 TI - Recurrent Patellar Instabilty Culminating in a Vertically Rotated and a Locked Patellar Dislocation - A Rare Entity. AB - INTRODUCTION: Locked vertical patellar dislocations are rare and pose a therapeutic challenge. This case is more unusual, as the patient was a known case of recurrent patellar dislocation and presented with an atraumatic locked and vertically rotated patellar dislocation. This type of presentation has never been reported in literature to the best of our knowledge. CASE PRESENTATION: A 14-year old healthy male child with previous history of recurrent lateral dislocation of patella presented to accident & emergency department with complaints of inability to walk or bear weight on his left lower limb after he spontaneously dislocated his patella while running on uneven ground. Radiographs revealed a laterally displaced and vertically rotated patella along its long axis with the medial patellar edge locked and dipping into the lateral gutter. Open reduction was performed along with lateral patellar retinacular release with medial patellar retinaculum plication, to achieve satisfactory patellar stability and patellofemoral tracking. CONCLUSION: We would recommend that in the settings of patella being vertically dislocated and locked, open reduction would be the management of choice, as these types of dislocations are difficult to relocate by closed reduction. Repeated attempts of closed reduction may cause osteochondral damage. Open reduction not only yields better outcomes but also allows the surgeon to perform patellar realignment procedures in order to prevent further patellar dislocations in cases of prior patellar instability. PMID- 27703949 TI - A Case Report of Curettage and Kryptonite(r) use in Proximal Femur Intraosseous Lipoma. AB - INTRODUCTION: Intraosseous lipomas are the most infrequent primary bone tumor, lesions are mainly asymptomatic and generally diagnosed incidentally, and there is controversy about the management. Here, we present a surgery solution that has not been described previously in literature. CASE PRESENTATION: A 23-year-old female without previous morbid history consults a general physician because of unspecific left hip pain when walking, not related to any previous trauma or any other symptoms. In her study, radiography of the sore hip showed a radiopaque lesion with lithic aspect at the neck of the left femur. CONCLUSION: Intraosseous lipoma, in spite of being a rare condition, can be diagnosed incidentally by its radiologic characteristics. The treatment can be based on observation or surgery in particular cases objectified by clinic and Mirel score. PMID- 27703951 TI - ? PMID- 27703950 TI - Acute Cholecystitis Following Total Knee Replacement: A Case Report and Literature Review. AB - INTRODUCTION: Infection poses a substantial challenge after joint replacement. CASE PRESENTATION: We report a 53-year-old female with multiple co-morbidities, who underwent unilateral total knee arthroplasty. Her postoperative course was complicated by acute cholecystitis necessitating cholecystectomy. CONCLUSION: In patients who require joint replacement surgery, careful and detailed preoperative assessment is important to identify those at risk for this complication in order to provide timely treatment. PMID- 27703952 TI - The Value of Urodynamic Study for Diagnosing the Causes of Lower Urinary Tract Symptoms in Male Patients: A Study From Iran. AB - BACKGROUND: Most disorders of the lower urinary tract are functional, so diagnoses are typically based on urodynamic findings. Treatment is likely to fail if the pathology is not correctly diagnosed. OBJECTIVES: There are various diagnostic tests for lower urinary tract symptoms (LUTS). In this study, we evaluated the value of urodynamic testing to diagnose the causes of lower urinary symptoms in male patients. PATIENTS AND METHODS: Urodynamic tests were performed in 407 patients referred to the urology clinic in Baqiyatallah in 2014 with complaints of LUTS, and the diagnosis was based on the findings of the tests. RESULTS: The mean age of patients in this study was 50.88 years, and most patients were in their third decade (20 - 30 years of age). Urinary frequency (28.8%), enuresis (22.22%), and incontinence (16.12%) were the most common complaints. The most prevalent disorder was bladder sensation disorder. CONCLUSIONS: Patients made various complaints, and several pathologies were diagnosed, which emphasizes the importance of using urodynamic tests for subsequent medical approaches as a non-invasive, accessible, and inexpensive tool. PMID- 27703953 TI - Primary Nocturnal Enuresis: A Review. AB - CONTEXT: Nocturnal enuresis or bedwetting is the most common type of urinary incontinence in children. It has significant psychological effects on both the child and the family. Enuresis nocturna is defined as the inability to hold urine during the night in children who have completed toilet training. It is termed as being "primary" if no continence has ever been achieved or "secondary if it follows at least 6 months of dry nights. The aim of this review was to assemble the pathophysiological background and general information about nocturnal enuresis. EVIDENCE ACQUISITION: This review was performed by evaluating the literature on nocturnal enuresis published between 1970 and 2015, available via PubMed and using the keywords "nocturnal enuresis," "incontinence," "pediatric," "review," and "treatment." RESULTS: Children with nocturnal enuresis produce urine at higher rates during the night, and may have lower bladder capacities. Some children with nocturnal enuresis may also have daytime urgency, frequency, and urinary incontinence. Treatment includes aggressive treatment of accompanying constipation or urinary tract infections, behavioral changes, and medical therapy. Alarm therapy remains the first-line treatment modality for primary nocturnal enuresis. High rates of patient compliance and relapse mean that alternative treatments remain on the agenda. CONCLUSIONS: Nocturnal enuresis is a common problem that has multifaceted effects on both the child and the family. Due to multiple etiologic factors, nocturnal enuresis is still not clearly defined. PMID- 27703954 TI - Multimodal Analgesia With Ketamine or Tramadol in Combination With Intravenous Paracetamol After Renal Surgery. AB - BACKGROUND: Opioids are generally the preferred analgesic agents during the early postoperative period. OBJECTIVES: The present study was designed to assess and compare the multimodal analgesic effects of ketamine and tramadol in combination with intravenous acetaminophen after renal surgery. PATIENTS AND METHODS: This randomized, double-blinded, clinical trial was conducted on 80 consecutive patients undergoing various types of kidney surgeries in Sina hospital in Tehran in 2014 - 2016. After extubation, the patients were randomly assigned to receive intravenous paracetamol (1 gr) plus tramadol (0.7 mg/kg) (PT group) or paracetamol (1 gr) plus ketamine (0.5 mg/kg) (PK group) within ten minutes. Pain severity was assessed by the visual analog scale (VAS), and the level of agitation was assessed by the Ramsey sedation scale (RSS). Morphine consumption was assessed within the first six hours after drug injection, and hemodynamic parameters were assessed at 5, 10, and 20 minutes after infusion, at the time of transfer from recovery to the ward, and also at one and six hours after transfer to the ward. RESULTS: Postoperative pain scores were significantly lower in the PK group than in the PT group during all study time points. The mean dose of morphine needed at recovery in the PK group was lower compared with the PT group (0.47 +/- 0.94 mg versus 1.50 +/- 1.35 mg/P = 0.001). The level of agitation based on the RSS score was significantly lower in the PK group than in the PT group at 10 and 20 minutes after drug administration. The total postoperative complication rate in the PK group was lower than in the PT group (20% versus 53.3%, P = 0.007). In this regard, catheter bladder discomfort was more frequent in the PT group than in the PK group (43.3% versus 3.3%, P < 0.001). CONCLUSIONS: The combination of intravenous paracetamol 1 gr and ketamine 0.5 mg/kg resulted in an overall reduction in pain scores, decreased postoperative analgesic requirements, and lower agitation score compared with intravenous paracetamol 1 gr and tramadol 0.7 mg/kg for patients undergoing renal surgery. PMID- 27703955 TI - A Novel Technique for Post-Prostatectomy Catheter Traction. AB - BACKGROUND: Prostate traction is one way to control post-prostatectomy bleeding. The most popular method involves traction with a catheter fixed to the thigh with adhesive bands. However, this method has its own drawbacks. OBJECTIVES: We aimed to simplify this traction procedure and to overcome its disadvantages. PATIENTS AND METHODS: From 2007 - 2015, a new method was used to control post prostatectomy bleeding in 152 patients. This technique involved inducing pressure on the prostate neck with an indwelling catheter attached to a partially filled urine bag to control bleeding after a prostatectomy. RESULTS: The new method effectively controlled post-prostatectomy bleeding. A few patients required surgical intervention. CONCLUSIONS: Post-prostatectomy catheter traction using a semi-filled urine bag was an acceptable alternative to the standard method to control post-operative bleeding. PMID- 27703956 TI - Burden of Hypertension and Abnormal Glomerular Permeability in Hypertensive School Children. AB - BACKGROUND: Childhood hypertension has been associated with target-organ damage in young adults. It is often asymptomatic in both children and adolescents; when persistent, and long-standing, it could be a significant risk factor for kidney damage and increased glomerular permeability. OBJECTIVES: Burden of hypertension and its impact on glomerular permeability were prospectively determined in randomly recruited primary school children. PATIENTS AND METHODS: Blood pressure (BP) measurement was performed by the auscultation method, and abnormal glomerular permeability was assessed by dipstick testing of urine for persistent proteinuria and/or hematuria for >= three months in hypertensive children. RESULTS: Of 1,335 pupils aged 10.0 +/- 2.4 (6.0 - 14.0) years, 33 (2.5%) were hypertensive. Overall mean systolic/diastolic BP was 125.6 +/- 6.5/81.7 +/- 3.3 (range: 114.0 - 140.0/80.0 - 90.0) mmHg. Nine (27.3%) had combined systolic and diastolic hypertension, 126.7 +/- 5.7/80.0 - 80.0 +/- 0.0 (120.0 - 130.0/80.0 - 80.0) mmHg. Isolated systolic hypertension, 125.4 +/- 6.7 (114.0 - 140.0) mmHg, was present in 14 (42.4%), whereas 10 (30.3%) had isolated diastolic hypertension, 82.0 +/- 3.5 (80.0 - 90.0) mmHg. Mean systolic and diastolic BP were 131.0 +/- 3.3 (130.0 - 140.0) mmHg and 86.5 +/- 4.43 (80.0 - 90.0) mmHg, respectively. According to the dipstick test, none of the hypertensive pupils showed urinalysis evidence of proteinuria and/or hematuria after three months of testing. CONCLUSIONS: Although the burden of hypertension was 2.5%, the dipstick method did not detect any hypertension-related abnormal glomerular permeability in the school children. PMID- 27703957 TI - Primary Renal Primitive Neuroectodermal Tumor/Ewing's Sarcoma Imaging and Pathologic Findings of a Patient with a Nine Year, Eight Month Disease Free Period: Case Report and Review of Literature. AB - INTRODUCTION: Primitive neuroectodermal tumor (PNET)/Ewing's sarcoma (EWS) belongs to a family of neoplasms that are presumed to originate from the neuroectodermal crest. PNET/EWSs are highly aggressive malignancies that usually present in the form of bone or soft tissue masses and usually affect adolescents and young adults. Primary PNET/EWS of the kidney is very rare. CASE PRESENTATION: We present the case of a 32-year-old female patient with primary renal PNET/EWS diagnosed nine years and eight months earlier. The patient presented with acute flank pain in the left lumbar region, hematuria, and episodes of high body temperature of 40 degrees C. Abdominal ultrasound (US) and subsequently performed computed tomography (CT) revealed a large renal mass of heterogenous structure. The kidney tumor had central necrotic hypodense areas and strongly peripherally enhanced solid parts on postcontrast CT images. Immunohistochemistry revealed positivity for CD99 and neuron-specific enolase (NSE). Tumor cells were negative for CD3, CD 20, chromogranin, synaptophysin, vimentin, and neurofilament. Reverse transcription polymerase change reaction (RT-PCR) revealed EWS/FL1 translocation type 2. The patient underwent nephrectomy and polychemotherapy. The follow-up nine years and eight months after the diagnosis showed no evidence of tumor. CONCLUSIONS: PNET/EWS should be included in the differential diagnosis of renal tumors in symptomatic young adults. Patients with localised PNET/EWS treated with a combination of surgery and chemotherapy have an excellent chance of long-term survival, as in the case we have presented. PMID- 27703958 TI - Temporal Patterns of Road Traffic Injuries in Iran. AB - BACKGROUND: Road traffic injuries (RTIs) are the main causes of death and disability in Iran. However, very few studies about the temporal variations of RTIs have been published to date. OBJECTIVES: This study was conducted to investigate the temporal pattern of RTIs in Iran in 2012. MATERIALS AND METHODS: All road traffic accidents (RTAs) reported to traffic police during a one-year period (March 21, 2012 through March 21, 2013) were investigated after obtaining permission from the law enforcement force of the Islamic Republic of Iran. Distributions of RTAs were obtained for season, month, week, and hour scales, and for long holidays (more than one day) and the day prior to long holidays (DPLH). The final analysis was carried out using the Poisson regression model to calculate incidence rate ratios for RTIs. All analyses were conducted using STATA 13.1 and Excel software; statistical significance was set at P < 0.05. RESULTS: A total of 452,192 RTAs were examined. The estimated rate of all accidents was 219 per 10,000 registered vehicles, or 595 per 100,000 people. About 28% of all RTAs, and more than one third of fatal RTAs, occurred during the summer months. The incidence rate for all traffic accidents on DPLH was 1.20, compared to workdays as a reference category, and it was 1.40 for fatal crashes. The rate of fatal road traffic accidents in outer cities was 3.2 times higher than in inner ones. CONCLUSIONS: Our findings reveal that there are temporal variations in traffic accidents, and long holidays significantly influence accident rates. Traffic injuries have different patterns on outer/inner city roads, based on weekday and holiday status. Thus, these findings could be used to create effective initiatives aimed at traffic management. PMID- 27703959 TI - A Systematic Review of Iranian Experiences in Seismo-Nephrology. AB - CONTEXT: Crush syndrome and its potentially life-threatening complications, such as acute kidney injury (AKI), are one of the most important medical problems of disaster victims. However, today, many unanswered questions abound about the potential risk factors of crush syndrome, predictive factors of AKI, proper amount of prophylactic hydration therapy, type of fluid, time of continuing fluid, intravenous versus oral hydration, etc. Therefore, this study was designed to review the findings on Iranian nephrologist experiences in diagnosis and management of traumatic rhabdomyolysis following the last two strong earthquakes of Bam (2003) and Manjil-Rudbar (1990). EVIDENCE ACQUISITION: The study was conducted according to the MOOSE reporting guideline. A literature review was conducted on the nephrologic aspects of earthquakes in Iran. Relevant articles were identified through a comprehensive search of online databases until 2014. The search was limited to articles studying the Iranian population published in English and Persian languages. The validated combination of MeSH terms and key words was used. In addition, a manual search was run among the references of all articles that met the entrance criteria and previous reviews. Only cohort, case control, and cross-sectional studies were enrolled. Two reviewers independently reviewed the eligible studies, and another reviewer contributed in case of a disagreement. Basic information from each study was evaluated from the aspects of purpose and design, year of publication, methodology, main population, and source of data. The quality of the included studies was assessed using methods guide for effectiveness and comparative effectiveness reviews. Two reviewers independently rated each paper as "good", "fair", or "poor". RESULTS: A total of 1256 non duplicate articles were identified, but only 35 potentially relevant papers were screened. Finally, 21 articles were found eligible and studied in details. In addition, one unpublished report was included. In the quality assessment, two articles had poor quality, and thus only 20 were finally included in the systematic review. No publication bias (coefficient = -2.28; 95% Confidence interval: -6.17 - 1.78; P = 0.26) was observed among the included studies. CONCLUSIONS: A few eligible articles on seismo-nephrology were found in Iran, and a limited number of current articles had poor or fair quality. As expected, the chaotic situation after mass disasters and the lack of documentation led to the loss of much important data on the diagnosis and management of victims. Lessons learned from the current researches can be used as a valuable guide for future studies. PMID- 27703960 TI - Effect of Mild Traumatic Brain Injury and Demographic Factors on Psychological Outcome. AB - BACKGROUND: It is well-known that severe brain injury can make people susceptible to psychological symptoms. However, mild traumatic brain injury (MTBI) is still open for discussion. OBJECTIVES: This study aimed to compare psychological symptoms of MTBI patients with those without MTBI considering demographic auxiliary variables. PATIENTS AND METHODS: This prospective cohort study was conducted on 50 MTBI patients and 50 healthy subjects aged 15 - 65 years. Psychological assessment was carried out six months post-injury using a series of self-report measures including the brief symptom inventory (BSI) scale. Other information of the individuals in the two groups was recorded prospectively. Data were analyzed using the chi-square test, t-test, and multiple linear regression tests. RESULTS: There was a significant difference between the MTBI patients and healthy subjects in all subscales and total score of BSI. Our findings showed that obsession-compulsion and anxiety subscales were significantly more common in the MTBI patients than in the healthy subjects. Also, multivariate regression analysis six months post- injury showed that head trauma and substance abuse can have an effect on psychological symptoms. CONCLUSIONS: Mild traumatic brain injuries despite of the normal CT scan and history of substance abuse are closely related to psychological symptoms. Therefore, it is recommended that patients with brain trauma 6 months post-injury and subjects with a history of substance abuse be evaluated for psychological distress to support better rehabilitation.

PMID- 27703962 TI - Role of regorafenib as second-line therapy and landscape of investigational treatment options in advanced hepatocellular carcinoma. AB - Sorafenib is still the only systemic drug approved for the treatment of advanced hepatocellular carcinoma (HCC). In recent years, several investigational agents mainly targeting angiogenesis failed in late-phase clinical development due to either toxicity or lack of benefit. Recently, data of the RESORCE trial, a placebo-controlled Phase III study that evaluated the efficacy and safety of regorafenib in patients with HCC and documented disease progression after systemic first-line treatment with sorafenib, were presented at the ESMO World Congress on Gastrointestinal Cancer, 2016. Regorafenib treatment resulted in a 2.8-month survival benefit compared to placebo (10.6 months vs 7.8 months). Side effects were consistent with the known profile of regorafenib. The approval of regorafenib for this indication is expected in 2017. Further candidate agents in Phase III evaluation for second-line treatment of patients with HCC are the MET inhibitors tivantinib and cabozantinib, the vascular endothelial growth factor receptor-2 antibody ramucirumab, and the programmed death receptor-1 (PD-1) blocking antibody pembrolizumab. Furthermore, results from two first-line trials with either the tyrosine kinase inhibitor lenvatinib or the PD-1 antibody nivolumabin in comparison to sorafenib are awaited in the near future and might further change the treatment sequence of advanced HCC. PMID- 27703963 TI - Does alpha-fetoprotein contribute to the mortality and morbidity of human hepatocellular carcinoma? A commentary. AB - The fifth most common cancer worldwide is hepatocellular carcinoma (HCC), while being the third leading cause of global cancer-related deaths. Although HCC incidence is less frequent in North America, it is a common malignancy in Asia and Africa associated with a high rate of mortality and morbidity due to ineffective therapies against cancer growth, invasion, and metastasis. It is well established that serum alpha-fetoprotein (AFP) is the "gold standard" biomarker for liver cancer; however, less known are the biological activities of AFP regarding carcinogenesis, growth, proliferation, and metastasis. Clinicians are well aware that increasing AFP serum levels parallel disease progression of HCC patients, but many are less knowledgeable in the lethal growth-promoting properties of AFP as an autocrine stimulator of hepatoma cell proliferation. This commentary addresses the mortality and morbidity concerning AFP in the genesis, growth, progression, and spread of HCC and emphasizes the perilous consequences of AFP-supported growth in human liver cancer even after liver resection and transplantation. Thus, AFP is not just a biomarker for HCC but also an ardent promoter of liver cancer growth and progression. PMID- 27703964 TI - Job Maintenance through Supported Employment PLUS: A Randomized Controlled Trial. AB - Sickness absence from work due to experienced distress and mental health issues has continuously increased over the past years in Germany. To investigate how this alarming development can be counteracted, we conducted a randomized controlled trial evaluating a job coaching intervention to maintain the working capacity of members of staff and ultimately prevent sickness absence. Our sample included N = 99 employees who reported mental distress due to work-related problems. The intervention group (n = 58) received between 8 and 12 individual job coaching sessions in which they worked with a professional job coach to reduce their mental distress. The control group (n = 41) received a brochure about mental distress. Data were collected before the start of the study, at the end of the job coaching intervention, and at a 3-month follow-up. These data included the number of sickness absence days as the primary outcome and questionnaire measures to assess burnout indicators, life satisfaction, and work related experiences and behaviors. Compared with the control group, the results indicated no reduction in sickness absence in the intervention group but fewer depressive symptoms, a heightened ability of the participants to distance themselves from work, more experience of work-related success, less depletion of emotional resources, and a greater satisfaction with life when participants had received the job coaching. Thus, although we could not detect a reduction in sickness absence between the groups, job coaching was shown to be a viable intervention technique to benefit employees by contributing to re-establish their mental health. We discuss the implications of the study and outline future research. PMID- 27703965 TI - Occupational Practitioner's Role in the Management of a Crisis: Lessons Learned from the Paris November 2015 Terrorist Attack. AB - In massive catastrophic events, occupational health practitioners are more and more frequently involved in the management of such situations. We aim to describe the multiple aspects of the role that occupational health practitioners might play, by focusing on the recent example of the Paris terrorist attack of November 2015. During and after the Paris attack, occupational practitioners, in collaboration with emergency and security professionals, were involved in psychological care, assembling information, follow-up, return-to-work, and improving in-company safety plans. Based on this experience and other industrial disasters, we distinguish three phases: the critical phase, the post-critical phase, and the anticipation phase. In the critical phase, the occupational practitioner cares for patients before the emergency professionals take charge, initiates the psychological management, and may also play an organizational role for company health aspects. In the post-critical phase, he or she would be involved in monitoring those affected by the events and participate in preventing, to the extent possible, posttraumatic stress disorder, helping victims in the return-to-work process, and improving procedures and organizing drills. In addition to their usual work of primary prevention, occupational practitioners should endeavor to improve preparedness in the anticipation phase, by taking part in contingency planning, training in first aid, and defining immediately applicable protocols. In conclusion, recent events have highlighted the essential role of occupational health services in anticipation of a crisis, management during the crisis, and follow-up. PMID- 27703966 TI - Marked QTc Prolongation and Torsades de pointes in Patients with Chronic Inflammatory Arthritis. AB - Mounting evidence indicates that in chronic inflammatory arthritis (CIA), QTc prolongation is frequent and correlates with systemic inflammatory activation. Notably, basic studies demonstrated that inflammatory cytokines induce profound changes in potassium and calcium channels resulting in a prolonging effect on cardiomyocyte action potential duration, thus on the QT interval on the electrocardiogram. Moreover, it has been demonstrated that in rheumatoid arthritis (RA) patients, the risk of sudden cardiac death is significantly increased when compared to non-RA subjects. Conversely, to date no data are available about torsades de pointes (TdP) prevalence in CIA, and the few cases reported considered CIA only an incidental concomitant disease, not contributing factor to TdP development. We report three patients with active CIA developing marked QTc prolongation, in two cases complicated with TdP degenerating to cardiac arrest. In these patients, a blood sample was obtained within 24 h from TdP/marked QTc prolongation occurrence, and levels of IL-6, TNFalpha, and IL-1 were evaluated. In all three cases, IL-6 was markedly elevated, ~10 to 100 times more than reference values. Moreover, one patient also showed high circulating levels of TNFalpha and IL-1. In conclusion, active CIA may represent a currently overlooked QT-prolonging risk factor, potentially contributing in the presence of other "classical" risk factors to TdP occurrence. In particular, a relevant role may be played by elevated circulating IL-6 levels via direct electrophysiological effects on the heart. This fact should be carefully kept in mind, particularly when recognizable risk factors are already present and/or the addition of QT prolonging drugs is required. PMID- 27703967 TI - Persistent Type I Endoleak after Endovascular Treatment with Chimney Technique. AB - Thoracic endovascular aortic repair (TEVAR) is increasingly used in the treatment of acute type B aortic dissection. Type Ia endoleaks are a common complication of the procedure, but its clinical significance and the best treatment strategy remain poorly defined. We present a case of a type Ia endoleak following TEVAR in the treatment of acute type B aortic dissection. Chimney technique approach was used in an attempt to seal the endoleak. Although technical success was suboptimal, the patient remained clinically stable and event free. Data regarding the natural course and management of type Ia endoleaks following TEVAR for aortic dissection are sparse. Future research is required to establish the clinical and technical determinants of the need to treat these endoleaks and the best treatment strategy. PMID- 27703968 TI - G-1639A but Not C1173T VKORC1 Gene Polymorphism Is Related to Ischemic Stroke and Its Various Risk Factors in Ukrainian Population. AB - Vitamin K epoxide reductase complex subunit 1 (VKORC1) is integral 163-amino acid long transmembrane protein which mediates recycling of vitamin K 2,3-epoxide to vitamin K hydroquinone and it is necessary for activation of vitamin K-dependent proteins (VKDPs). Herein, the association between G-1639A (rs9923231) and C1173T (rs9934438) single-nucleotide polymorphisms (SNPs) of the VKORC1 gene and ischemic stroke (IS) was tested in Ukrainian population. Genotyping was performed in 170 IS patients and 124 control subjects (total 294 DNA samples) using PCR RFLP (polymerase chain reaction with following restriction fragment length polymorphism analysis) method. Our data showed that G-1639A but not C1173T polymorphism was related to IS, regardless of adjustment for age, sex, body mass index, smoking status, and arterial hypertension. The risk for IS in -1639A allele carriers (OR = 2.138, P = 0.015) was higher than in individuals with G/G genotype. Haplotype analysis demonstrated that -1639G/1173T and -1639A/1173C were related to increased risk for IS (OR = 3.813, P = 0.010, and OR = 2.189, P = 0.011, resp.), while -1639G/1173C was a protective factor for IS (OR = 0.548, P < 0.001). Obtained results suggested that -1639A allele can be a possible genetic risk factor for IS in Ukrainian population.

PMID- 27703969 TI - Identification and Characterization of Small Noncoding RNAs in Genome Sequences of the Edible Fungus Pleurotus ostreatus. AB - Noncoding RNAs (ncRNAs) have been identified in many fungi. However, no genome scale identification of ncRNAs has been inventoried for basidiomycetes. In this research, we detected 254 small noncoding RNAs (sncRNAs) in a genome assembly of an isolate (CCEF00389) of Pleurotus ostreatus, which is a widely cultivated edible basidiomycetous fungus worldwide. The identified sncRNAs include snRNAs, snoRNAs, tRNAs, and miRNAs. SnRNA U1 was not found in CCEF00389 genome assembly and some other basidiomycetous genomes by BLASTn. This implies that if snRNA U1 of basidiomycetes exists, it has a sequence that varies significantly from other organisms. By analyzing the distribution of sncRNA loci, we found that snRNAs and most tRNAs (88.6%) were located in pseudo-UTR regions, while miRNAs are commonly found in introns. To analyze the evolutionary conservation of the sncRNAs in P. ostreatus, we aligned all 254 sncRNAs to the genome assemblies of some other Agaricomycotina fungi. The results suggest that most sncRNAs (77.56%) were highly conserved in P. ostreatus, and 20% were conserved in Agaricomycotina fungi. These findings indicate that most sncRNAs of P. ostreatus were not conserved across Agaricomycotina fungi. PMID- 27703971 TI - The Economic Burden of Otitis Media in Korea, 2012: A Nationally Representative Cross-Sectional Study. AB - Background. Otitis media (OM) is a common communicable disease that is associated with a substantial economic burden. However, no Korean studies have evaluated OM related trends after the introduction of the pneumococcal conjugate vaccines. Purpose. This study aimed to estimate the prevalence and economic burden of OM in Korea using nationally representative data. Methods. The burden of OM was estimated nationally representative data such as national health insurance claims data from 2012, based on the prevalence approach and the societal perspective. Results. In 2012, 1,788,303 patients visited medical institutions for treatment of OM, and the prevalence and burden of OM were 3.5% and 497.35 million US dollars, respectively. Patients who were 0-9 years old accounted for 59.7% of the cases and 55.2% of the total cost. Among adults, the total and perpatient costs were highest among 50-59-year-old adults. Direct medical costs and outpatient costs accounted for large proportions of the total cost (86.3% and 88.3%, resp.). Conclusion. The economic burden of OM decreased after the introduction of the pneumococcal conjugate vaccines. However, OM is still associated with a relatively large burden, especially among adults, and interventions are needed to reduce the burden of OM in this population. PMID- 27703973 TI - Assessment of the Utility of the Septal E/(E' * S') Ratio and Tissue Doppler Index in Predicting Left Ventricular Remodeling after Acute Myocardial Infarction. AB - Background. The aim of this study is to show whether the septal E/(E' * S') ratio assessed by tissue Doppler echocardiography can predict left ventricular remodeling after first ST segment elevation myocardial infarction treated successfully with primary percutaneous intervention. Methods. Consecutive patients (n = 111) presenting with acute anterior myocardial infarction for the first time in their life were enrolled. All patients underwent successful primary percutaneous coronary intervention. Standard and tissue Doppler echocardiography were performed in the first 24-36 hours of admission. Echocardiographic examination was repeated after 6 months to reassess left ventricular volumes. Septal E/(E' * S') ratio was assessed by pulsed Doppler echocardiography. Results. Group 1 consisted of 33 patients with left ventricular (LV) remodeling, and Group 2 had 78 patients without LV remodeling. E/(E' * S') was significantly higher in Group 1 (4.1 +/- 1.9 versus 1.65 +/- 1.32, p = 0.001). The optimal cutoff value for E/(E' * S') ratio was 2.34 with 87.0% sensitivity and 82.1% specificity. Conclusion. Septal E/(E' * S') values measured after the acute anterior myocardial infarction can strongly predict LV remodeling in the 6-month follow-up. In the risk assessment, the septal E/(E' * S') can be evaluated together with the conventional echocardiographic techniques. PMID- 27703974 TI - Use of NeuroEyeCoachTM to Improve Eye Movement Efficacy in Patients with Homonymous Visual Field Loss. AB - Visual field deficits are common in patients with damaged retinogeniculostriate pathways. The patient's eye movements are often affected leading to inefficient visual search. Systematic eye movement training also called compensatory therapy is needed to allow patients to develop effective coping strategies. There is a lack of evidence-based, clinical gold-standard registered medical device accessible to patients at home or in clinical settings and NeuroEyeCoach (NEC) is developed to address this need. In three experiments, we report on performance of patients on NEC compared to the data obtained previously on the earlier versions of the search task (n = 32); we assessed whether the self-administered computerised tasks can be used to monitor the progress (n = 24) and compared the findings in a subgroup of patients to a healthy control group. Performance on cancellation tasks, simple visual search, and self-reported responses on activities of daily living was compared, before and after training. Patients performed similarly well on NEC as on previous versions of the therapy; the inbuilt functionality for pre- and postevaluation functions was sensitive to allowing assessment of improvements; and improvements in patients were significantly greater than those in a group of healthy adults. In conclusion, NeuroEyeCoach can be used as an effective rehabilitation tool to develop compensatory strategies in patients with visual field deficits after brain injury.

PMID- 27703976 TI - Blood Pressure Response to Submaximal Exercise Test in Adults. AB - Background. The assessment of blood pressure (BP) response during exercise test is an important diagnostic instrument in cardiovascular system evaluation. The study aim was to determine normal values of BP response to submaximal, multistage exercise test in healthy adults with regard to their age, gender, and workload. Materials and Methods. The study was conducted in randomly selected normotensive subjects (n = 1015), 512 females and 498 males, aged 18-64 years (mean age 42.1 +/- 12.7 years) divided into five age groups. All subjects were clinically healthy with no chronic diseases diagnosed. Exercise stress tests were performed using Monark bicycle ergometer until a minimum of 85% of physical capacity was reached. BP was measured at rest and at peak of each exercise test stage. Results. The relations between BP, age, and workload during exercise test were determined by linear regression analysis and can be illustrated by the equations: systolic BP (mmHg) = 0.346 * load (W) + 135.76 for males and systolic BP (mmHg) = 0.103 * load (W) + 155.72 for females. Conclusions. Systolic BP increases significantly and proportionally to workload increase during exercise test in healthy adults. The relation can be described by linear equation which can be useful in diagnostics of cardiovascular diseases.

AB - The shell of the pearl oyster (Pinctada fucata) mainly comprises aragonite whereas that of the Pacific oyster (Crassostrea gigas) is mainly calcite, thereby suggesting the different mechanisms of shell formation between above two mollusks. Calmodulin (CaM) is an important gene for regulating the uptake, transport, and secretion of calcium during the process of shell formation in pearl oyster. It is interesting to characterize the CaM in oysters, which could facilitate the understanding of the different shell formation mechanisms among mollusks. We cloned the full-length cDNA of Pacific oyster CaM (cgCaM) and found that the cgCaM ORF encoded a peptide of 113 amino acids containing three EF-hand calcium-binding domains, its expression level was highest in the mantle, hinting that the cgCaM gene is probably involved in shell formation of Pacific oyster, and the common ancestor of Gastropoda and Bivalvia may possess at least three CaM genes. We also found that the numbers of some EF hand family members in highly calcified species were higher than those in lowly calcified species and the numbers of these motifs in oyster genome were the highest among the mollusk species with whole genome sequence, further hinting the correlation between CaM and biomineralization. PMID- 27703979 TI - A Meta-Path-Based Prediction Method for Human miRNA-Target Association. AB - MicroRNAs (miRNAs) are short noncoding RNAs that play important roles in regulating gene expressing, and the perturbed miRNAs are often associated with development and tumorigenesis as they have effects on their target mRNA. Predicting potential miRNA-target associations from multiple types of genomic data is a considerable problem in the bioinformatics research. However, most of the existing methods did not fully use the experimentally validated miRNA-mRNA interactions. Here, we developed RMLM and RMLMSe to predict the relationship between miRNAs and their targets. RMLM and RMLMSe are global approaches as they can reconstruct the missing associations for all the miRNA-target simultaneously and RMLMSe demonstrates that the integration of sequence information can improve the performance of RMLM. In RMLM, we use RM measure to evaluate different relatedness between miRNA and its target based on different meta-paths; logistic regression and MLE method are employed to estimate the weight of different meta paths. In RMLMSe, sequence information is utilized to improve the performance of RMLM. Here, we carry on fivefold cross validation and pathway enrichment analysis to prove the performance of our methods. The fivefold experiments show that our methods have higher AUC scores compared with other methods and the integration of sequence information can improve the performance of miRNA-target association prediction.

PMID- 27703980 TI - Advanced Hemodynamic Management in Patients with Septic Shock. AB - In patients with sepsis and septic shock, the hemodynamic management in both early and later phases of these "organ dysfunction syndromes" is a key therapeutic component. It needs, however, to be differentiated between "early goal-directed therapy" (EGDT) as proposed for the first 6 hours of emergency department treatment by Rivers et al. in 2001 and "hemodynamic management" using advanced hemodynamic monitoring in the intensive care unit (ICU). Recent large trials demonstrated that nowadays protocolized EGDT does not seem to be superior to "usual care" in terms of a reduction in mortality in emergency department patients with early identified septic shock who promptly receive antibiotic therapy and fluid resuscitation. "Hemodynamic management" comprises (a) making the diagnosis of septic shock as one differential diagnosis of circulatory shock, (b) assessing the hemodynamic status including the identification of therapeutic conflicts, and (c) guiding therapeutic interventions. We propose two algorithms for hemodynamic management using transpulmonary thermodilution-derived variables aiming to optimize the cardiocirculatory and pulmonary status in adult ICU patients with septic shock. The complexity and heterogeneity of patients with septic shock implies that individualized approaches for hemodynamic management are mandatory. Defining individual hemodynamic target values for patients with septic shock in different phases of the disease must be the focus of future studies. PMID- 27703982 TI - Styloid Process of the Temporal Bone: Morphometric Analysis and Clinical Implications. AB - Objective. To evaluate measures of the styloid process (SP) in Brazilian dry skulls. Methods. This study involves measurements of two points (lateral end posterior views) of 15 dry skulls held by the Morphology Department, Institute of Biological Sciences of Federal University of Minas Gerais. Results. There was a large variability for the length of left and right sides (in lateral and posterior views) of the styloid process. From the lateral view of the left and right styloid, the length of the SP ranged, respectively, from 10.22 mm to 69.73 mm and from 8.30 mm to 63.77 mm. From a posterior view of the left and right sides of the skulls, the values range, respectively, from 15.57 mm to 69.51 mm and from 15.64 mm to 69.44 mm. Conclusion. We believe that this study provides additional information about the frequency of elongated SP among the Brazilian population. PMID- 27703983 TI - Comparing McGRATH(r) MAC, C-MAC(r), and Macintosh Laryngoscopes Operated by Medical Students: A Randomized, Crossover, Manikin Study. AB - We hypothesized that the McGRATH MAC would decrease the time of intubation compared to C-MAC for novices. Thirty-nine medical students who had used the Macintosh blade to intubate a manikin fewer than 3 times were recruited. The participants performed sequential intubations on the manikin in two simulated settings that included a normal airway and a difficult airway (tongue edema). The intubation time, success rate of intubation, Cormack-Lehane grade at laryngoscopy, and difficulty using the device were recorded. Each participant was asked to identify the device that was most useful. The intubation time decreased significantly and by a similar amount to the McGRATH MAC and C-MAC compared to the Macintosh blade (P < 0.001 and P = 0.017, resp.). In the difficult airway, the intubation times were similar among the three devices. The McGRATH MAC and C MAC significantly increased the success rate of intubation, improved the Cormack Lehane grade, and decreased the difficulty score compared to the Macintosh blade in both airway settings. The majority of participants selected the McGRATH MAC as the most useful device. The McGRATH MAC and C-MAC may offer similar benefits for intubation compared to the Macintosh blade in normal and difficult airway situations. PMID- 27703984 TI - Efficacy and Safety of a Permethrin-Fipronil Spot-On Solution (Effitix(r)) in Dogs Naturally Infested by Ticks in Europe. AB - Effitix is a new broad spectrum product based on the combination of fipronil 6.1% and permethrin 54.5% in a solution for spot-on application. It has been shown to be safe and efficacious in dogs in controlling tick, flea, sandfly, and mosquito infestations in laboratory conditions. The aim of this controlled, randomised study was to assess its safety and efficacy against natural tick infestations in field conditions. One hundred eighty-two privately owned dogs were included in France and Germany: 123 dogs were treated on day 0 with the permethrin-fipronil combination (Effitix) and 59 with a permethrin-imidacloprid combination (Advantix(r)). Tick counts were conducted on days 0 (before treatment), 7, 14, 21, and 28. The percentages of efficacy on days 7, 14, 21, and 28 were, respectively, 91.2%, 97%, 98.3%, and 96.7% with Effitix and were 94.8%, 96.9%, 95.7%, and 94.6% with Advantix. Very few adverse events were reported. Most were not serious and/or not related to the treatment with pruritus being the most common. One administration of Effitix was highly effective and safe to treat and control tick infestations for four weeks in field conditions and had a similar efficacy as the permethrin-imidacloprid combination for all visits. PMID- 27703985 TI - Developing a Conceptually Equivalent Type 2 Diabetes Risk Score for Indian Gujaratis in the UK. AB - Aims. To apply and assess the suitability of a model consisting of commonly used cross-cultural translation methods to achieve a conceptually equivalent Gujarati language version of the Leicester self-assessment type 2 diabetes risk score. Methods. Implementation of the model involved multiple stages, including pretesting of the translated risk score by conducting semistructured interviews with a purposive sample of volunteers. Interviews were conducted on an iterative basis to enable findings to inform translation revisions and to elicit volunteers' ability to self-complete and understand the risk score. Results. The pretest stage was an essential component involving recruitment of a diverse sample of 18 Gujarati volunteers, many of whom gave detailed suggestions for improving the instructions for the calculation of the risk score and BMI table. Volunteers found the standard and level of Gujarati accessible and helpful in understanding the concept of risk, although many of the volunteers struggled to calculate their BMI. Conclusions. This is the first time that a multicomponent translation model has been applied to the translation of a type 2 diabetes risk score into another language. This project provides an invaluable opportunity to share learning about the transferability of this model for translation of self completed risk scores in other health conditions. PMID- 27703986 TI - The Yin and Yang of the Opioid Growth Regulatory System: Focus on Diabetes-The Lorenz E. Zimmerman Tribute Lecture. AB - The Opioid Growth Regulatory System consists of opioid growth factor (OGF), [Met5]-enkephalin, and its unique receptor (OGFr). OGF inhibits cell division when bound to OGFr. Conversely, blockade of the interaction of OGF and OGFr, using the potent, long-acting opioid receptor antagonist, naltrexone (NTX), results in increased DNA synthesis and cell division. The authors have demonstrated both in vitro and in vivo that the addition of exogenous OGF or an increase in available OGFr decreases corneal epithelial cell division and wound healing. Conversely, blockade of the OGF-OGFr interaction by NTX or a decrease in the production of the OGFr increases corneal epithelial cell division and facilitates corneal epithelial wound healing. The authors also have demonstrated that depressed corneal and cutaneous wound healing, dry eye, and abnormal corneal sensitivity in type 1 and type 2 diabetes in animals can be reversed by OGF-OGFr blockade by NTX. Thus, the function of the Opioid Growth Regulatory System appears to be disordered in diabetic animals, and its function can be restored with NTX treatment. These studies suggest a fundamental role for the Opioid Growth Regulatory System in the pathobiology of diabetic complications and a need for studies to elucidate this role further. PMID- 27703987 TI - Immunomodulatory Effects of 1,25-Dihydroxyvitamin D3 on Dendritic Cells Promote Induction of T Cell Hyporesponsiveness to Myelin-Derived Antigens. AB - While emerging evidence indicates that dendritic cells (DC) play a central role in the pathogenesis of multiple sclerosis (MS), their modulation with immunoregulatory agents provides prospect as disease-modifying therapy. Our observations reveal that 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) treatment of monocyte-derived DC results in a semimature phenotype and anti-inflammatory cytokine profile as compared to conventional DC, in both healthy controls and MS patients. Importantly, 1,25(OH)2D3-treated DC induce T cell hyporesponsiveness, as demonstrated in an allogeneic mixed leukocyte reaction. Next, following a freeze-thaw cycle, 1,25(OH)2D3-treated immature DC could be recovered with a 78% yield and 75% viability. Cryopreservation did not affect the expression of membrane markers by 1,25(OH)2D3-treated DC nor their capacity to induce T cell hyporesponsiveness. In addition, the T cell hyporesponsiveness induced by 1,25(OH)2D3-treated DC is antigen-specific and robust since T cells retain their capacity to respond to an unrelated antigen and do not reactivate upon rechallenge with fully mature conventional DC, respectively. These observations underline the clinical potential of tolerogenic DC (tolDC) to correct the immunological imbalance in MS. Furthermore, the feasibility to cryopreserve highly potent tolDC will, ultimately, contribute to the large-scale production and the widely applicable use of tolDC. PMID- 27703988 TI - Association Between Gambling and Exposure to Guns Among Cocaine-Using Women. AB - The purpose of this study is to assess the association between gambling severity and exposure to guns among substance-using women recruited in the community. Data for these analyses come from the baseline phase of two community-based HIV prevention interventions conducted among alcohol and drug-using women in St. Louis, MO. Gun exposure was assessed using the Violence Exposure Questionnaire (VEQ), and DSM-IV pathological gambling (PG) symptoms and other psychiatric symptoms were assessed using the Computerized Diagnostic Interview Schedule; The Composite International Diagnostic Interview Substance Abuse Module assessed DSM IV substance dependence, including cocaine dependence and alcohol dependence. Women in the study were predominantly African American (80%), mean age was 35.70 years +/-8.8. Women exposed to guns were significantly more likely than women not exposed to guns to have gambled with all consequences: without meeting PG criteria (21% vs. 15%); to meet 1 to 4 PG criteria (22% vs. 12%), and to report 5 or more PG criteria (10% vs. 5%). These differences were significant at p < 0.0001. Based on the multivariate analysis, women who gambled without PG symptoms (OR = 1.77; 95% CI = 1.10-2.85) were nearly twice more likely to have exposure to guns than women who did not gamble. The risk for gun exposure increased with severity of gambling. Women who gambled and reported one to four PG criteria were twice as likely to have had an exposure to guns (OR 2.04; 95% CI = 1.45-3.06) and this risk increased to nearly threefold among women who met five or more criteria of PG (OR 2.65; 95% CI = 1.32-5.32). In addition, endorsing five or more criteria for major depressive disorder (OR 1.44; 95% CI = 1.00-2.06) and three or more criteria for antisocial personality adult criteria (OR 3.78; 95% CI = 2.03-7.02) were strong predictors for gun exposure among these women. The findings indicate that substance-using women with gambling behavior are at an enhanced risk to have exposure to guns.

Candida albicans transcriptomes at the infection site distinguished treated from untreated cholangitis. After treatment, 1131 C. albicans genes were differentially expressed in biliary fluid. Up-regulated genes were enriched in hyphal growth, cell wall organization, adhesion, oxidation reduction, biofilm, and fatty acid and ergosterol biosynthesis. This is the first study to define Candida global gene expression during deep-seated human infection. Successful treatment of cholangitis induced C. albicans genes involved in fluconazole responses and pathogenesis. PMID- 27703991 TI - Impact of a Telehealth Program That Delivers Remote Consultation and Longitudinal Mentorship to Community HIV Providers. AB - Background. To increase human immunodeficiency virus (HIV) care capacity in our region, we designed a distance mentorship and consultation program based on the Project ECHO (Extension for Community Healthcare Outcomes) model, which uses real time interactive video to regularly connect community providers with a multidisciplinary team of academic specialists. This analysis will (1) describe key components of our program, (2) report types of clinical problems for which providers requested remote consultation over the first 3.5 years of the program, and (3) evaluate changes in participants' self-assessed HIV care confidence and knowledge over the study period. Methods. We prospectively tracked types of clinical problems for which providers sought consultation. At baseline and regular intervals, providers completed self-efficacy assessments. We compared means using paired-samples t test and examined the statistical relationship between each survey item and level of participation using analysis of variance. Results. Providers most frequently sought consultation for changing antiretroviral therapy, evaluating acute symptomatology, and managing mental health issues. Forty-five clinicians completed a baseline and at least 1 repeat assessment. Results demonstrated significant increase (P < .05) in participants' self-reported confidence to provide a number of essential elements of HIV care. Significant increases were also reported in feeling part of an HIV community of practice and feeling professionally connected to academic faculty, which correlated with level of program engagement. Conclusions. Community HIV practitioners frequently sought support on clinical issues for which no strict guidelines exist. Telehealth innovation increased providers' self-efficacy and knowledge while decreasing professional isolation. The ECHO model creates a virtual network for peer-to-peer support and longitudinal mentorship, thus strengthening capacity of the HIV workforce. PMID- 27703992 TI - Deciphering the Effects of Injectable Pre-exposure Prophylaxis for Combination Human Immunodeficiency Virus Prevention. AB - Background. A long-acting injectable formulation of rilpivirine (RPV), under investigation as antiretroviral pre-exposure prophylaxis (PrEP), may facilitate PrEP adherence. In contrast, cross-resistance between RPV and nonnucleoside reverse-transcriptase inhibitors comprising first-line antiretroviral therapy (ART) could promote human immunodeficiency virus (HIV) drug resistance and reduce PrEP's effectiveness. Methods. We use novel mathematical modeling of different RPV PrEP scale-up strategies in KwaZulu-Natal, South Africa, to investigate their effects on HIV prevention and drug resistance, compared with a reference scenario without PrEP. Results. Pre-exposure prophylaxis scale-up modestly increases the proportion of prevalent drug-resistant infections, from 33% to <=37%. The change in the number of prevalent drug-resistant infections depends on the interplay between PrEP factors (coverage, efficacy, delivery reliability, and scale-up strategy) and the level of cross-resistance between PrEP and ART. An optimistic scenario of 70% effective RPV PrEP (90% efficacious and 80% reliable delivery), among women aged 20-29 years, prevents 17% of cumulative infections over 10 years while decreasing prevalent resistance; however, prevention decreases and resistance increases with more conservative assumptions. Uncertainty analysis assuming 40%-70% cross-resistance prevalence predicts an increase in prevalent resistance unless PrEP's effectiveness exceeds 90%. Conclusions. Prioritized scale-up of injectable PrEP among women in KwaZulu-Natal could reduce HIV infections, but suboptimal effectiveness could promote the spread of drug resistance.

Phylogenetic relationships were inferred using a bootstrapped maximum likelihood tree based on core genome sequence polymorphisms. Accessory traits were compared between phylogenetically similar isolates. Results. In the WGS based phylogeny, isolates clustered strictly by household, in clades that were distributed widely across the phylogeny, interspersed between H30R1 and H30Rx comparison genomes. For only 1 household did the core genome phylogeny place epidemiologically unlinked isolates together with household isolates, but even there multiple differences in accessory genome content clearly differentiated these 2 groups. The core genome phylogeny supported within-household strain sharing, fecal-urethral urinary tract infection pathogenesis (with the entire household potentially providing the fecal reservoir), and instances of host specific microevolution. In 1 instance, the household's index strain persisted for 6 years before causing a new infection in a different household member. Conclusions. Within-household sharing of E coli ST131 strains was confirmed extensively at the genome level, as was long-term colonization and repeated infections due to an ST131-H30Rx strain. Future efforts toward surveillance and decolonization may need to address not just the affected patient but also other human and animal household members. PMID- 27703994 TI - Disseminated Mycobacterium chimaera Infection After Cardiothoracic Surgery. AB - Ten case reports of disseminated Mycobacterium chimaera infections associated with cardiovascular surgery were published from Europe. We report 3 cases of disseminated M chimaera infections with histories of aortic graft and/or valvular surgery within the United States. Two of 3 patients demonstrated ocular involvement, a potentially important clinical finding. PMID- 27703995 TI - Clearance of Vancomycin-Resistant Enterococcus Concomitant With Administration of a Microbiota-Based Drug Targeted at Recurrent Clostridium difficile Infection. AB - Background. Vancomycin-resistant Enterococcus (VRE) is a major healthcare associated pathogen and a well known complication among transplant and immunocompromised patients. We report on stool VRE clearance in a post hoc analysis of the Phase 2 PUNCH CD study assessing a microbiota-based drug for recurrent Clostridium difficile infection (CDI). Methods. A total of 34 patients enrolled in the PUNCH CD study received 1 or 2 doses of RBX2660 (microbiota suspension). Patients were requested to voluntarily submit stool samples at baseline and at 7, 30, and 60 days and 6 months after the last administration of RBX2660. Stool samples were tested for VRE using bile esculin azide agar with 6 ug/mL vancomycin and Gram staining. Vancomycin resistance was confirmed by Etest. Results. VRE status (at least 1 test result) was available for 30 patients. All stool samples for 19 patients (63.3%, mean age 61.7 years, 68% female) tested VRE negative. Eleven patients (36.7%, mean age 75.5 years, 64% female) were VRE positive at the first test (baseline or 7-day follow-up). Of these patients, 72.7%, n = 8 converted to negative as of the last available follow-up (30 or 60 days or 6 months). Of the other 3: 1 died (follow-up data not available); 1 patient remained positive at all follow-ups; 1 patient retested positive at 6 months with negative tests during the interim. Conclusions. Although based on a small sample size, this secondary analysis demonstrated the possibility of successfully converting a high percentage of VRE-positive patients to negative in a recurrent CDI population with RBX2660. PMID- 27703996 TI - Host Biomarkers Are Associated With Response to Therapy and Long-Term Mortality in Pediatric Severe Malaria. AB - Background. Host responses to infection are critical determinants of disease severity and clinical outcome. The development of tools to risk stratify children with malaria is needed to identify children most likely to benefit from targeted interventions. Methods. This study investigated the kinetics of candidate biomarkers of mortality associated with endothelial activation and dysfunction (angiopoietin-2 [Ang-2], soluble FMS-like tyrosine kinase-1 [sFlt-1], and soluble intercellular adhesion molecule-1 [sICAM-1]) and inflammation (10 kDa interferon gamma-induced protein [CXCL10/IP-10] and soluble triggering receptor expressed on myeloid cells-1 [sTREM-1]) in the context of a randomized, double-blind, placebo controlled, parallel-arm trial evaluating inhaled nitric oxide versus placebo as adjunctive therapy to parenteral artesunate for severe malaria. One hundred eighty children aged 1-10 years were enrolled at Jinja Regional Referral Hospital in Uganda and followed for up to 6 months. Results. There were no differences between the 2 study arms in the rate of biomarker recovery. Median levels of Ang 2, CXCL10, and sFlt-1 were higher at admission in children who died in-hospital (n = 15 of 180; P < .001, P = .027, and P = .004, respectively). Elevated levels of Ang-2, sTREM-1, CXCL10, and sICAM-1 were associated with prolonged clinical recovery times in survivors. The Ang-2 levels were also associated with postdischarge mortality (P < .0001). No biomarkers were associated with neurodisability. Conclusions. Persistent endothelial activation and dysfunction predict survival in children admitted with severe malaria. PMID- 27703997 TI - Community-Onset Bloodstream and Other Infections, Caused by Carbapenemase Producing Enterobacteriaceae: Epidemiological, Microbiological, and Clinical Features. AB - Background. Because most infections caused by carbapenemase-producing Enterobacteriaceae (CPE) begin during hospitalization, there are limited data about community-onset (CO) infections caused by CPE. Our aim is to describe the frequency of CO infections caused by CPE as well as the clinical features of CO bloodstream infections (CO-BSIs). Methods. This study includes retrospective case series of CO infections caused by CPE in a tertiary hospital from January 2010 to July 2014. Any clinical sample with a positive culture for CPE that had been ordered by primary care doctors or by doctors at the emergency room (ER) were classified as CO. Epidemiological and microbiological features of CO cases were assessed as were clinical features of CO-BSIs. Results. Of 780 clinical samples with CPE, 180 were requested at the ER or by primary care doctors (22.9%), 150 of which were produced by Klebsiella pneumoniae (83.3%). The blaOXA 48 gene was detected in 149 isolates (82.8%) followed by the blaVIM gene, 29 (16.1%). Sixty-one patients (33.9%) had a prior history of CPE infection/colonization. Thirty-four of the 119 (28.6%) patients without prior history of CPE infection/colonization did not fulfill Friedman criteria for healthcare-associated infections (HAIs). Considering previous hospitalization of up to 12 months as a criterion for defining HAI, only 16 (13.4%) cases were identified as community-acquired infections. The most frequent positive sample was urine (133 of 180; 73.9%). Twenty-one (11.7%) patients had a BSI, 9 of them secondary to urinary tract infections (42.9%). Thirty-day crude mortality among patients with BSI was 23.8% (5 of 21). Conclusions. Community-onset infections caused by CPE are an important subgroup of all CPE infections. The urinary tract is the main source. Bloodstream infections accounted for more than 10% of the cases. PMID- 27703998 TI - Favorable Socioeconomic Status and Recreational Polydrug Use Are Linked With Sexual Hepatitis C Virus Transmission Among Human Immunodeficiency Virus-Infected Men Who Have Sex With Men. AB - Background. Sexual transmission of hepatitis C virus (HCV) among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) is an emerging issue. Studies addressing the temporal trends and risk factors associated with incident HCV in HIV-infected MSM in the community-based primary care settings in the United States are scarce. Methods. Using a retrospective cohort study design, HCV incidence, defined as HCV antibody seroconversion, was determined in 1147 HIV-infected men receiving care at Chase Brexton Health Care clinics in Baltimore, Maryland between 2004 and 2014. Multivariate regression analyses were used to identify factors associated with incident HCV. Results. There were 42 incident HCV infections during 5242 person-years (PY) of follow up (incidence rate [IR], 8.01/1000 PY). Thirty-seven (88%) of the incident infections were in MSM, of whom 31 (84%) reported no injection-drug use (IDU). The annual IRs for MSM were 13.1-15.8/1000 PY between 2004 and 2007, decreased to 2.7-6.2/1000 PY between 2008 and 2011, and increased to 10.4/1000 PY and 13.3/1000 PY in 2013 and 2014, respectively. Injection-drug use was strongly associated with incident HCV among all MSM (IR ratio [IRR], 14.15; P = .003); however, among MSM without IDU, entering care between 2010 and 2013 (IRR, 3.32; P = .01), being employed (IRR, 3.14; P = .03), and having a history of ulcerative sexually transmitted infections (IRR, 3.70; P = .009) or of polydrug use (IRR, 5.54; P = .01) independently predicted incident HCV. Conclusions. In this cohort of HIV-infected men, a re-emerging HCV epidemic was observed from 2011 to 2014 among MSM. In addition to IDU, high-risk sexual behaviors, favorable socioeconomic status, and polydrug use fueled this increase in HCV infections. PMID- 27703999 TI - The Niche for Escherichia coli Sequence Type 131 Among Veterans: Urinary Tract Abnormalities and Long-Term Care Facilities. AB - Background. Antimicrobial resistance among Escherichia coli is increasing, driven largely by the global emergence of sequence type 131 (ST131). However, the clinical significance of ST131 status is unknown. Among veterans, we assessed whether ST131 causes more severe, persistent, or recurrence-prone infections than non-ST131 E. coli. Methods. Isolates were assessed by polymerase chain reaction for membership in ST131 and relevant subclones thereof (H30R and H30Rx) and by broth microdilution for susceptibility to 11 antibiotics. Clinical and epidemiological data were systematically abstracted from the medical record. Between-group comparisons were made using t tests and Fisher's exact test. Results. Of the 311 unique E. coli isolates, 61 (19.6%) represented ST131. Of these, most (51 of 61, 83.6%) represented the H30R subclone; only 5 of 51 (9.8%) represented H30Rx. Relative to non-ST131 and non-H30R isolates, neither ST131 nor H30R were associated with more severe disease, worse clinical outcomes, or more robust hosts. Instead, both were more likely to be isolated from patients without manifestations of infection (for ST131, 36.1% vs 21.2% [P = .02]; for H30R, 39% vs 21% [P = .008]) and who had prior healthcare contact or long-term care facility (LTCF) exposure (for ST131, 33% vs 14% [P = .002]; for H30R, 37% vs 14% [P < .001]). Despite a greater likelihood of discordant initial therapy, outcomes did not differ between ST131 and H30R isolates vs other E. coli isolates. Conclusions. Among veterans, ST131 and its H30R subclone were associated with LTCF-exposed hosts but not with worse outcomes. PMID- 27704000 TI - A Randomized Switch From Nevirapine-Based Antiretroviral Therapy to Single Tablet Rilpivirine/Emtricitabine/Tenofovir Disoproxil Fumarate in Virologically Suppressed Human Immunodeficiency Virus-1-Infected Rwandans. AB - Background. Many human immunodeficiency virus (HIV)-infected patients remain on nevirapine-based antiretroviral therapy (ART) despite safety and efficacy concerns. Switching to a rilpivirine-based regimen is an alternative, but there is little experience with rilpivirine in sub-Saharan Africa where induction of rilpivirine metabolism by nevirapine, HIV subtype, and dietary differences could potentially impact efficacy. Methods. We conducted an open-label noninferiority study of virologically suppressed (HIV-1 ribonucleic acid [RNA] < 50 copies/mL) HIV-1-infected Rwandan adults taking nevirapine plus 2 nucleos(t)ide reverse transcriptase inhibitors. One hundred fifty participants were randomized 2:1 to switch to coformulated rilpivirine-emtricitabine-tenofovir disoproxil fumarate (referenced as the Switch Arm) or continue current therapy. The primary efficacy endpoint was HIV-1 RNA < 200 copies/mL at week 24 assessed by the US Food and Drug Administration Snapshot algorithm with a noninferiority margin of 12%. Results. Between April and September 2014, 184 patients were screened, and 150 patients were enrolled; 99 patients switched to rilpivirine-emtricitabine tenofovir, and 51 patients continued their nevirapine-based ART. The mean age was 42 years and 43% of participants were women. At week 24, virologic suppression (HIV-1 RNA level <200 copies/mL) was maintained in 93% and 92% in the Switch Arm versus the continuation arm, respectively. The Switch Arm was noninferior to continued nevirapine-based ART (efficacy difference 0.8%; 95% confidence interval, -7.5% to +12.0%). Both regimens were generally safe and well tolerated, although 2 deaths, neither attributed to study medications, occurred in participants in the Switch Arm. Conclusions. A switch from nevirapine-based ART to rilpivirine-emtricitabine-tenofovir disoproxil fumarate had similar virologic efficacy to continued nevirapine-based ART after 24 weeks with few adverse events. PMID- 27704001 TI - Evaluation of Two Techniques for Viral Load Monitoring Using Dried Blood Spot in Routine Practice in Vietnam (French National Agency for AIDS and Hepatitis Research 12338). AB - Background. Although it is the best method to detect early therapeutic failure, viral load (VL) monitoring is still not widely available in many resource-limited settings because of difficulties in specimen transfer, personnel shortage, and insufficient laboratory infrastructures. Dried blood spot (DBS) use, which was introduced in the latest World Health Organization recommendations, can overcome these difficulties. This evaluation aimed at validating VL measurement in DBS, in a laboratory without previous DBS experience and in routine testing conditions. Methods. Human immunodeficiency virus (HIV)-infected adults were observed in a HIV care site in Hanoi, and each patient provided 2 DBS cards with whole blood spots and 2 plasma samples. Viral load was measured in DBS and in plasma using the COBAS Ampliprep/TaqMan and the Abbott RealTime assays. To correctly identify those with VL >= 1000 copies/mL, sensitivity and specificity were estimated. Results. A total of 198 patients were enrolled. With the Roche technique, 51 plasma VL were >=1000 copies/mL; among these, 28 presented a VL in DBS that was also >=1000 copies/mL (sensitivity, 54.9; 95% confidence interval [CI], 40.3 68.9). On the other hand, all plasma VL < 1000 copies/mL were also <1000 copies/mL in DBS (specificity, 100; 95% CI, 97.5-100). With the Abbott technique, 45 plasma VL were >=1000 copies/mL; among these, 42 VL in DBS were also >=1000 copies/mL (sensitivity, 93.3%; 95% CI, 81.7-98.6); specificity was 94.8 (95% CI, 90.0-97.7). Conclusions. The Abbott RealTime polymerase chain reaction assay provided adequate VL results in DBS, thus allowing DBS use for VL monitoring. PMID- 27704002 TI - Optimal Treatment for Complicated Intra-abdominal Infections in the Era of Antibiotic Resistance: A Systematic Review and Meta-Analysis of the Efficacy and Safety of Combined Therapy With Metronidazole. AB - Background. Carbapenem-resistant Enterobacteriaceae has increased dramatically in the last decade, resulting in infections that are difficult to treat and associated with high mortality rates. To prevent further antibacterial resistance, it is necessary to use carbapenem selectively. A combination of metronidazole with an antimicrobial agent active against aerobes is an alternative effective treatment for patients with complicated intra-abdominal infections (cIAIs). This study aimed to compare efficacy and safety of metronidazole combination therapies and carbapenem and to provide clinical evidence regarding the optimal treatment of cIAI. Methods. A systematic review and a meta-analysis of randomized clinical trials in the treatment of cIAI were conducted. The systematic review with PubMed, Embase, and the Cochrane Database of Systematic Reviews followed the Cochrane Handbook's recommended methodology, and the meta-analysis used a Mantel-Haenszel random-effects model with RevMan, version 5.3. Primary endpoints were clinical success and bacteriological eradication, and secondary endpoints were all-cause mortality and drug-related adverse events. Results. Eight studies comparing metronidazole combination therapies and carbapenem were included in the meta-analysis. No difference was found between combined therapy with metronidazole and carbapenem regarding clinical success (odds ratio [OR] = 1.31; 95% confidence interval [CI], .75 2.31), bacteriological eradication (OR = 1.27; 95% CI, .84-1.91), all-cause mortality (OR = 0.61; 95% CI, .37-1.00), or drug-related adverse events (OR = 0.58; 95% CI, .18-1.88). Sensitivity analyses found similar results. Conclusions. Combined therapy with metronidazole is as effective and safe as carbapenem in treatment of cIAI. Therefore, combined therapy with metronidazole offers an effective alternative to carbapenem with low risk of drug resistance.

The patient presented with fevers, nausea, and abdominal pain and clinically improved after shunt removal. NTM identification was performed by amplicon and whole genome sequencing. PMID- 27704005 TI - Preliminary Evaluation of a Sitafloxacin-Containing Regimen for Relapsed or Refractory Pulmonary Mycobacterium avium Complex Disease. AB - Although sitafloxacin (STFX) is known to have a favorable minimum inhibitory concentration for Mycobacterium avium, few studies have evaluated the clinical efficacy of an STFX-containing regimen for pulmonary M avium complex (MAC) disease. To evaluate the clinical efficacy of STFX-containing regimens for relapsed or refractory pulmonary MAC disease, we retrospectively reviewed 18 patients with pulmonary MAC disease who received STFX for at least 4 weeks for pulmonary MAC disease between January 2008 and February 2016. Of 18 patients, 10 (55.6%) showed improved radiological characteristics and 8 (44.4%) showed negative sputum cultures at 6 months. Regarding the clinical symptoms, improvements were observed in decreasing order in sputum production (77.8%), cough (72.2%), and malaise (55.6%). Common adverse events included nausea or vomiting (38.9%), followed by loose stool or diarrhea (27.8%) and sleepiness (11.1%). Although this study contained a small number of subjects, we describe a STFX-containing regimen that was effective in achieving sputum culture negative conversions and had an acceptable adverse events profile. PMID- 27704006 TI - Shewanella-Related Bacteremia and Fournier's Gangrene: A Case Report. AB - Shewanella algae and Shewanella putrefaciens have been implicated for causing serious infections in humans, including disseminated infection. We report the possible first case of Shewanella-related Fournier's gangrene and bacteremia caused in a 65-year-old Chinese male with nephrotic syndrome. He was successfully managed by surgical debridement and antibiotic therapy. PMID- 27704007 TI - Widespread Rift Valley Fever Emergence in Senegal in 2013-2014. AB - Rift Valley fever (RVF), which caused epizootics and epidemics among human and livestock populations, occurred in Senegal in 2013-2014. A multidisciplinary field investigation was carried out in 3 regions of Senegal. We found 11 confirmed human cases of Rift Valley fever, including severe cases with encephalitis and retinitis, 1 pool of mosquito (Aedes ochraceus), and 52 animals tested positive for the disease. Symptoms such as encephalitis and macular retinitis were the most severe cases reported so far in Senegal. The outbreak was widespread due to animals' movements, leading to the largest RVF outbreak in Senegal in terms of geographic spreading and reaching areas that never reported RVF activity previously. PMID- 27704008 TI - Clinical Impact on Tuberculosis Treatment Outcomes of Discordance Between Molecular and Growth-Based Assays for Rifampin Resistance, California 2003-2013. AB - Background. Data from international settings suggest that isolates of Mycobacterium tuberculosis with rpoB mutations testing phenotypically susceptible to rifampin (RIF) may have clinical significance. We analyzed treatment outcomes of California patients with discordant molecular-phenotypic RIF results. Methods. We included tuberculosis (TB) patients, during 2003-2013, whose specimens tested RIF susceptible phenotypically but had a rpoB mutation determined by pyrosequencing. Demographic data were abstracted from the California TB registry. Phenotypic drug-susceptibility testing, medical history, treatment, and outcomes were abstracted from medical records. Results. Of 3330 isolates tested, 413 specimens had a rpoB mutation (12.4%). Of these, 16 (3.9%) had molecular phenotypic discordant RIF results. Seven mutations were identified: 511Pro, 516Phe, 526Asn, 526Ser (AGC and TCC), 526Cys, and 533Pro. Fourteen (88%) had isoniazid (INH) resistance, 6 of whom were also phenotypically resistant to ethambutol (EMB) and/or pyrazinamide (PZA). Five patients (25%), 1 with 511Pro and 4 with 526Asn, relapsed or failed treatment. The initial regimen for 3 patients was RIF, PZA, and EMB; 1 patient received RIF, PZA, EMB, and a fluoroquinolone (FQN); and 1 patient received RIF, EMB, FQN, and some second-line medications. Upon retreatment with an expanded regimen, 3 (75%) patients completed treatment, 1 patient moved before treatment completion, and 1 patient continues on treatment. The remaining 11 patients had a successful outcome with 9 having received a FQN and/or a rifamycin. Conclusions. Rifampin molecular phenotypic discordance was rare, and most isolates had INH resistance. Patients who did not receive an expanded regimen had poor outcomes. These mutations may have clinical importance, and expanded treatment regimens should be considered. PMID- 27704009 TI - Penicillin Use in Meningococcal Disease Management: Active Bacterial Core Surveillance Sites, 2009. AB - In 2009, in the Active Bacterial Core surveillance sites, penicillin was not commonly used to treat meningococcal disease. This is likely because of inconsistent availability of antimicrobial susceptibility testing and ease of use of third-generation cephalosporins. Consideration of current practices may inform future meningococcal disease management guidelines. PMID- 27704010 TI - Human Immunodeficiency Virus-1 Sequence Changes and Drug Resistance Mutation Among Virologic Failures of Lopinavir/Ritonavir Monotherapy: AIDS Clinical Trials Group Protocol A5230. AB - Background. The mechanism of virologic failure (VF) of lopinavir/ritonavir (LPV/r) monotherapy is not well understood. We assessed sequence changes in human immunodeficiency virus-1 reverse-transcriptase (RT) and protease (PR) regions. Methods. Human immunodeficiency virus-1 pol sequences from 34 participants who failed second-line LPV/r monotherapy were obtained at study entry (SE) and VF. Sequence changes were evaluated using phylogenetic analysis and hamming distance. Results. Human immunodeficiency virus-1 sequence change was higher over drug resistance mutation (DRM) sites (median genetic distance, 2.2%; Q1 to Q3, 2.1% 2.5%) from SE to VF compared with non-DRM sites (median genetic distance, 1.3%; Q1 to Q3, 1.0%-1.4%; P < .0001). Evolution over DRM sites was mainly driven by changes in the RT (median genetic distance, 2.7%; Q1 to Q3, 2.2%-3.2%) compared with PR (median genetic distance, 1.1%; Q1 to Q3, 0.0%-1.1%; P < .0001). Most RT DRMs present at SE were lost at VF. At VF, 19 (56%) and 26 (76%) were susceptible to efavirenz/nevirapine and etravirine (ETV)/rilpivirine (RPV), respectively, compared with 1 (3%) and 12 (35%) at SE. Participants who retained nonnucleoside reverse-transcriptase inhibitor (NNRTI) DRMs and those without evolution of LPV/r DRMs had significantly shorter time to VF. Conclusions. The selection of LPV/r DRMs in participants with longer time to VF suggests better adherence and more selective pressure. Fading NNRTI mutations and an increase in genotypic susceptibility to ETV and RPV could allow for the reuse of NNRTI. Further studies are warranted to understand mechanisms of PR failure. PMID- 27704011 TI - Implementation of an Infectious Disease Fellow-Managed Penicillin Allergy Skin Testing Service. AB - Background. A large percentage of patients presenting to acute care facilities report penicillin allergies that are associated with suboptimal antibiotic therapy. Penicillin skin testing (PST) can clarify allergy histories but is often limited by access to testing. We aimed to implement an infectious diseases (ID) fellow-managed PST program and to assess the need for PST via national survey. Methods. We conducted a prospective observational study of the implementation of an ID fellow-managed penicillin allergy skin testing service. The primary outcome of the study was to assess the feasibility and acceptability of an ID fellow managed PST service and its impact on the optimization of antibiotic selection. In addition, a survey of PST practices was sent out to all ID fellowship program directors in the United States. Results. In the first 11 months of the program, 90 patients were assessed for PST and 76 patients were tested. Of the valid tests, 96% were negative, and 84% with a negative test had antibiotic changes; 63% received a narrower spectrum antibiotic, 80% received more effective therapy, and 61% received more cost-effective therapy. The majority of survey of respondents (n = 50) indicated that overreporting of penicillin allergy is a problem in their practice that affects antibiotic selection but listed inadequate personnel and time as the main barriers to PST. Conclusions. Inpatient PST can be successfully managed by ID fellows, thereby promoting optimal antibiotic use in patients reporting penicillin allergies. This model can increase access to PST at institutions without adequate access to allergists while also providing an important educational experience to ID trainees. PMID- 27704012 TI - Serum Fibrosis Markers for the Diagnosis of Liver Disease Among People With Chronic Hepatitis C in Chennai, India. AB - Background. Access to hepatitis C virus (HCV) treatment is limited in low- and middle-income countries (LMICs). Noninvasive biomarkers, such as fibrosis 4 (FIB 4) and aminotransferase to platelet ratio index (APRI), are low-cost alternatives to staging liver disease and identifying treatment need in people with chronic HCV infection, but their accuracy has not been evaluated in LMICs. Methods. We tested the accuracy of FIB-4 and APRI at validated cutoffs (FIB-4 <1.45, >3.25; APRI <0.5, >1.5) in predicting severe liver stiffness by elastography among 281 persons chronically infected with HCV. Multivariable logistic and Cox regression were used to identify markers of improved prediction and mortality, respectively. Results. Sensitivity and specificity of FIB-4 and APRI for predicting severe stiffness were 62% and 87% and 61% and 83%, respectively. Fibrosis 4 and APRI were less accurate in excluding significant stiffness; however, performance of models significantly improved with gamma-glutamyl transpeptidase (GGT) and body mass index (BMI) (area under receiver operating characteristic curve, 0.81; 95% confidence interval, .76-.87). Severe liver stiffness predicted via FIB-4 >3.25, APRI >1.5, and a modified FIB-4 that included GGT and BMI were significantly associated with increased mortality. Conclusions. Fibrosis 4 and APRI may be useful in identifying individuals with severe stiffness who need treatment and continued monitoring in LMICs. Exclusion of significant stiffness may be improved by including GGT and BMI to FIB-4 models.

PMID- 27704014 TI - Outpatient Antibiotic Prescribing Practices for Uncomplicated Urinary Tract Infection in Women in the United States, 2002-2011. AB - Background. Urinary tract infection (UTI) is one of the most common diagnoses leading to an antibiotic prescription for women seeking ambulatory care. Understanding current national outpatient antibiotic prescribing practices will help ongoing stewardship efforts to optimize antibiotic use; however, information on recent national outpatient antibiotic prescribing trends for UTI is limited. Methods. We analyzed the National Ambulatory Medical Care and National Hospital Ambulatory Medical Care Survey datasets from 2002 to 2011. Outpatient visits of women aged >=18 years with a diagnosis of uncomplicated UTI were included for analysis. We conducted weighted descriptive analyses, examined time trends in antibiotic prescribing, and used multivariable logistic regression to identify patient and provider factors associated with fluoroquinolone prescribing. Results. A total of 7111 visits were identified. Eighty percent of visits resulted in an antibiotic prescription; fluoroquinolones were the most frequently prescribed antibiotics throughout the study period (49% overall). Older patients (adjusted odds ratio [AOR] for adults aged >=70 years = 2.5; 95% confidence interval [CI], 1.6-3.8) and patients treated by internists (AOR = 2.0; 95% CI, 1.1-3.3) were more likely than younger patients and those treated by family practitioners to receive fluoroquinolones. Outpatient visits in the West US Census region were less likely to be associated with fluoroquinolone prescribing (AOR = 0.6; 95% CI, .4-1.0) compared with visits in the Northeast. Conclusions. Fluoroquinolones were the most frequently selected antibiotic treatment for uncomplicated UTI in women during the study period. Outpatient antibiotic stewardship initiatives should include efforts to reduce overuse of fluoroquinolones for uncomplicated UTI. PMID- 27704016 TI - Point-of-Care Viral Load Testing for Sub-Saharan Africa: Informing a Target Product Profile. AB - Point-of-care viral load tests are being developed to monitor patients on antiretroviral therapy (ART) in sub-Saharan Africa. Test design involves trade offs between test attributes, including accuracy, complexity, robustness, and cost. We used a model of the human immunodeficiency virus epidemic and ART program in Zimbabwe and found that the attributes of a viral load testing approach that are most influential for cost effectiveness are avoidance of a high proportion of failed tests or results not received, use of an approach that best facilitates retention on ART, and the ability to facilitate greater use of differentiated care, including through expanding coverage of testing availability. PMID- 27704015 TI - Pediatric Kawasaki Disease and Adult Human Immunodeficiency Virus Kawasaki-Like Syndrome Are Likely the Same Malady. AB - Background. Pediatric Kawasaki disease (KD) and human immunodeficiency virus (HIV)+ adult Kawasaki-like syndrome (KLS) are dramatic vasculitides with similar physical findings. Both syndromes include unusual arterial histopathology with immunoglobulin (Ig)A+ plasma cells, and both impressively respond to pooled Ig therapy. Their distinctive presentations, histopathology, and therapeutic response suggest a common etiology. Because blood is in immediate contact with inflamed arteries, we investigated whether KD and KLS share an inflammatory signature in serum. Methods. A custom multiplex enzyme-linked immunosorbent assay (ELISA) defined the serum cytokine milieu in 2 adults with KLS during acute and convalescent phases, with asymptomatic HIV+ subjects not taking antiretroviral therapy serving as controls. We then prospectively collected serum and plasma samples from children hospitalized with KD, unrelated febrile illnesses, and noninfectious conditions, analyzing them with a custom multiplex ELISA based on the KLS data. Results. Patients with KLS and KD subjects shared an inflammatory signature including acute-phase reactants reflecting tumor necrosis factor (TNF)-alpha biologic activity (soluble TNF receptor I/II) and endothelial/smooth muscle chemokines Ccl1 (Th2), Ccl2 (vascular inflammation), and Cxcl11 (plasma cell recruitment). Ccl1 was specifically elevated in KD versus febrile controls, suggesting a unique relationship between Ccl1 and KD/KLS pathogenesis. Conclusions. This study defines a KD/KLS inflammatory signature mirroring a dysfunctional response likely to a common etiologic agent. The KD/KLS inflammatory signature based on elevated acute-phase reactants and specific endothelial/smooth muscle chemokines was able to identify KD subjects versus febrile controls, and it may serve as a practicable diagnostic test for KD.

AB - Background. We evaluated the prevalence of chronic hepatitis B virus (HBV) infection and liver fibrosis/cirrhosis in human immunodeficiency virus (HIV) infected individuals enrolled in a rural Tanzanian prospective cohort and assessed hepatic fibrosis progression 12-24 months after antiretroviral treatment (ART) initiation. Methods. All ART-naive HIV-infected adults >=15-year-old enrolled in the Kilombero and Ulanga Antiretroviral Cohort who started ART between 2005 and 2015 were included. Pre-ART factors associated with significant liver fibrosis (aspartate aminotransferase-to-platelet ratio index [APRI] >1.5) and cirrhosis (APRI > 2.0) were identified using logistic regression. Results. Of 3097 individuals screened, 227 (7.3%; 95% CI, 6.4-8.2) were hepatitis B surface antigen (HBsAg) positive. Before ART initiation, 9.1% individuals had significant liver fibrosis and 5.3% had cirrhosis. Human immunodeficiency virus/HBV-coinfected individuals were more likely to have an APRI score indicating significant fibrosis (14.2% vs 8.7%, P = .03) and cirrhosis (9.2% vs 4.9%, P = .03) than HBV-uninfected patients. CD4 cell count <200 cell/MUL and alcohol consumption were independently associated with pre-ART APRI score, indicating significant fibrosis and cirrhosis in multivariable analyses. Among individuals with elevated APRI measurements pre- and 12-24 months post-ART initiation, 53 of 57 (93.0%) of HIV-monoinfected and 4 of 5 (80.0%) of HIV/HBV coinfected had a regression to APRI < 1.5. Conclusions. Hepatic fibrosis and cirrhosis were common in our cohort, especially among HIV/HBV-coinfected individuals. The APRI improved in most patients. Pre-ART HBsAg screening and early onset of tenofovir-based ART for HIV/HBV-coinfection should be prioritized in sub-Saharan Africa. PMID- 27704018 TI - Insurance Status and the Risk of Severe Respiratory Syncytial Virus Disease in United States Preterm Infants Born at 32-35 Weeks Gestational Age. AB - Background. Database studies have identified that public health insurance status is associated with an increased risk of severe respiratory syncytial virus (RSV) disease in US infants. However, these studies did not adjust for the presence of other risk factors and did not evaluate the risk in preterm infants. Methods. In this study, we evaluate the independent association between public insurance and severe RSV disease outcomes adjusting for other risk factors. The prospective, observational RSV Respiratory Events among Preterm Infants Outcomes and Risk Tracking (REPORT) study was conducted over 2 consecutive RSV seasons at 188 US clinical sites that enrolled preterm infants born at 32-35 wGA who had not received RSV immunoprophylaxis with palivizumab. Adjusted incidence rates per 100 infant-seasons of the RSV-associated endpoints of outpatient lower respiratory tract infection (LRI), emergency department (ED) visits, RSV hospitalizations (RSVHs), and intensive care unit admissions during peak RSV season (November March) were compared for infants with private and public insurance. Results. Of 1642 evaluable infants enrolled in the REPORT study, 50.1% had private insurance and 49.9% had public health insurance. Adjusted rates of RSV outpatient LRIs were similar; however, rates of ED visits (hazard ratio [HR], 2.04; 95% confidence interval [CI], 1.20-3.45) were higher for subjects with public insurance, with a similar but nonsignificant trend observed for hospitalization (HR, 1.61; 95% CI, .93-2.78). Conclusions. Socioeconomic status, as evaluated by public versus private healthcare insurance, is a significant independent risk factor for ED use in US preterm infants and may contribute to increased RSVHs in this population. PMID- 27704019 TI - Increase in Middle East Respiratory Syndrome-Coronavirus Cases in Saudi Arabia Linked to Hospital Outbreak With Continued Circulation of Recombinant Virus, July 1-August 31, 2015. AB - During July-August 2015, the number of cases of Middle East respiratory syndrome (MERS) reported from Saudi Arabia increased dramatically. We reviewed the 143 confirmed cases from this period and classified each based upon likely transmission source. We found that the surge in cases resulted predominantly (90%) from secondary transmission largely attributable to an outbreak at a single healthcare facility in Riyadh. Genome sequencing of MERS coronavirus from 6 cases demonstrated continued circulation of the recently described recombinant virus. A single unique frameshift deletion in open reading frame 5 was detected in the viral sequence from 1 case. PMID- 27704020 TI - Serum Amyloid P Component and Systemic Fungal Infection: Does It Protect the Host or Is It a Trojan Horse? AB - It is a striking observation that tissue of patients invaded by the deep mycoses often lacks evidence of an inflammatory response. This lack of host response is often attributed to neutropenia secondary to chemotherapy. However, systematic studies do not support this simplistic explanation. However, invasive fungal lesions are characterized by abundant fungal functional amyloid, which in turn is bound by serum amyloid P component (SAP). We postulate that SAP is important in the local immune response in invasive fungal infections. The interaction between fungal functional amyloid, SAP, and the immune response in deep mycoses is discussed. PMID- 27704021 TI - Pulmonary Cryptococcosis in the Immunocompetent Patient-Many Questions, Some Answers. AB - Background. There are no prospective data regarding the management of pulmonary cryptococcosis in the immunocompetent patient. Clinical guidelines recommend oral fluconazole for patients with mild to moderate symptoms and amphotericin B plus flucytosine followed by fluconazole for severe disease. It is unclear whether patients who have histological evidence of Cryptococcus neoformans but negative cultures will even respond to drug treatment. We evaluated and managed a patient whose presentation and course raised important questions regarding the significance of negative cultures, antifungal choices, duration of therapy, and resolution of clinical, serologic, and radiographic findings. Methods. In addition to our experience, to answer these questions we reviewed available case reports and case series regarding immunocompetent patients with pulmonary cryptococcosis for the last 55 years using the following definitions: Definite - Clinical and/or radiographic findings of pulmonary infection and respiratory tract isolation of C. neoformans without other suspected etiologies; Probable - Clinical and radiographic findings of pulmonary infection, histopathologic evidence of C. neoformans, and negative fungal cultures with or without a positive cryptococcal polysaccharide antigen. Results. Pulmonary cryptococcosis resolves in most patients with or without specific antifungal therapy. Clinical, radiographic, and serologic resolution is slow and may take years. Conclusions. Persistently positive antigen titers are most common in untreated patients and may remain strongly positive despite complete or partial resolution of disease. Respiratory fungal cultures are often negative and may indicate nonviable organisms. PMID- 27704022 TI - Outpatient Antibiotic Prescribing Among United States Nurse Practitioners and Physician Assistants. AB - We examined US nurse practitioner (NP) and physician assistant (PA) outpatient antibiotic prescribing. Antibiotics were more frequently prescribed during visits involving NP/PA visits compared with physician-only visits, including overall visits (17% vs 12%, P < .0001) and acute respiratory infection visits (61% vs 54%, P < .001). Antibiotic stewardship interventions should target NPs and PAs. PMID- 27704023 TI - Legionnaires' Disease Outbreak at a Resort in Cozumel, Mexico. AB - Background. A Legionnaires' disease (LD) outbreak at a resort on Cozumel Island in Mexico was investigated by a joint Mexico-United States team in 2010. This is the first reported LD outbreak in Mexico, where LD is not a reportable disease. Methods. Reports of LD among travelers were solicited from US health departments and the European Working Group for Legionella Infections. Records from the resort and Cozumel Island health facilities were searched for possible LD cases. In April 2010, the resort was searched for possible Legionella exposure sources. The temperature and total chlorine of the water at 38 sites in the resort were measured, and samples from those sites were tested for Legionella. Results. Nine travelers became ill with laboratory-confirmed LD within 2 weeks of staying at the resort between May 2008 and April 2010. The resort and its potable water system were the only common exposures. No possible LD cases were identified among resort workers. Legionellae were found to have extensively colonized the resort's potable water system. Legionellae matching a case isolate were found in the resort's potable water system. Conclusions. Medical providers should test for LD when treating community-acquired pneumonia that is severe or affecting patients who traveled in the 2 weeks before the onset of symptoms. When an LD outbreak is detected, the source should be identified and then aggressively remediated. Because LD can occur in tropical and temperate areas, all countries should consider making LD a reportable disease if they have not already done so. PMID- 27704024 TI - Invasive Aspergillosis Associated With Severe Influenza Infections. AB - Background. Invasive aspergillosis may occur in the setting of severe influenza infections due to viral-induced respiratory epithelium disruption and impaired immune effects, but data are limited. Methods. A retrospective study was conducted among severe influenza cases requiring medical intensive care unit (ICU) admission at an academic center during the 2015-2016 season. Data collected included respiratory cultures, medical conditions and immunosuppressants, laboratory and radiographic data, and outcomes. A systematic literature review of published cases in the English language of aspergillosis complicating influenza was conducted. Results. Six (75%) of 8 ICU influenza cases had Aspergillus isolated; 5 were classified as invasive disease. No ICU patient testing negative for influenza infection developed aspergillosis during the study period. Among cases with invasive aspergillosis, influenza infection was type A (H1N1) (n = 2) and influenza B (n = 3). Published and current cases yielded n = 57 (European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group criteria: 37% proven, 25% probable, and 39% possible cases). An increasing number of cases were reported since 2010. Sixty-five percent of cases lacked classic underlying conditions at admission for aspergillosis, 86% had lymphopenia, and 46% died. Conclusions. Aspergillosis may occur in the setting of severe influenza infections even among immunocompetent hosts. Risks may include influenza A (H1N1) or B infections and viral-induced lymphopenia, although further studies are needed. Prompt diagnosis and antifungal therapy are recommended given high mortality rates. PMID- 27704025 TI - Patterns of Healthcare Utilization Among Veterans Infected With Hepatitis C Virus (HCV) and Human Immunodeficiency Virus (HIV) and Coinfected With HIV/HCV: Unique Burdens of Disease. AB - Background. Hepatitis C virus (HCV) infection is a leading cause of cirrhosis and the primary cause of liver transplantation in the United States, and coinfection with human immunodeficiency virus (HIV) increases the risk of comorbidities. However, healthcare utilization (HCU) patterns among HIV/HCV coinfected patients are poorly understood. This study compared the rates of HCU and reasons for hospital admission among HCV-infected, HIV-infected, and HIV/HCV coinfected veterans. Methods. Hepatitis C virus- and HIV-infected and HIV/HCV coinfected veterans in care with the Department of Veterans Affairs (VA) from 1998 to 2009 (n = 335 371, n = 28 179, n = 13 471, respectively) were identified by HIV- and HCV-associated International Classification of Diseases, Ninth Revision codes from the clinical case registry. We assessed rates of HCU using emergency department (ED) visits, outpatient visits, and hospitalization and primary diagnoses associated with hospitalization. Independent risk factors associated with hospitalization were also examined. Results. Rates of outpatient and ED visits increased over the 11-year study period for all groups, with inpatient admission rates remaining stable. The HCU rates were consistently higher for the coinfected than other cohorts. The primary reason for hospital admission for all groups was psychiatric disease/substance use, accounting for 44% of all admissions. Nadir CD4 <350 cells/mm3 was associated with higher rates of hospitalization versus nadir CD4 >500 cells/mm3. Conclusions. As the current population of HCV-infected, HIV-infected, and HIV/HCV-coinfected veterans age, they will continue to place a substantial and increasing demand on the US healthcare system, particularly in their utilization of ED and outpatient services. These data suggest the need for an ongoing investment in mental health and primary care within the VA healthcare system. PMID- 27704026 TI - Changes in Insulin Resistance After Initiation of Raltegravir or Protease Inhibitors With Tenofovir-Emtricitabine: AIDS Clinical Trials Group A5260s. AB - Background. Antiretroviral therapy (ART) can alter glucose metabolism, but little data exist on the association of raltegravir (RAL) with insulin resistance. Methods. A5260s was a substudy of A5257, a prospective open-label randomized trial in which human immunodeficiency virus (HIV)-infected treatment naive participants were randomized to tenofovir-emtricitabine (TDF/FTC) plus atazanavir-ritonavir (ATV/r), darunavir-ritonavir (DRV/r), or RAL over 96 weeks. Baseline and changes in insulin resistance as estimated by the homeostatic model assessment of insulin resistance (HOMA-IR) were assessed. Wilcoxon rank-sum tests were used to assess shifts in the distribution of fold increase from baseline between treatment arms, and Spearman correlation was used to assess associations between HOMA-IR and measures of inflammation and body composition. Results. Three hundred twenty-eight participants were randomized; 90% were male, baseline median age was 36, HIV ribonucleic acid copies were 4.55 log10 copies/mL, and CD4 cell count was 349/mm3. Overall, HOMA-IR increased significantly after 4 weeks (1.9-fold change; 95% confidence interval, 1.73-2.05) then plateaued over the remainder of the study. Changes in HOMA-IR were not different between the arms (P >= .23). Changes in HOMA-IR were associated with changes in body mass index at weeks 48 and 96 (r = 0.12-0.22; P <= .04). There was a trend with increases in HOMA-IR and increases in visceral abdominal fat at week 96 (r = 0.12; P = .06). At 48 and 96 weeks, HOMA-IR correlated with interleukin-6, high-sensitivity C reactive protein, and soluble CD163 (r = 0.16-0.27; P <= .003). Conclusions. Insulin resistance increased rapidly and then plateaued in treatment-naive participants initiating ART with TDF/FTC, and no differences were found with RAL when compared with ATV/r or DRV/r.

PMID- 27704028 TI - CD4 Variability in Malawi: Implications for Use of a CD4 Threshold of 500 Cells/mm3 Versus Universal Eligibility for Antiretroviral Therapy. AB - Background. Given the uncertainty about the ability of a single CD4 count to accurately classify a patient as antiretroviral therapy (ART) eligible, we sought to understand the extent to which CD4 variability results in misclassification at a CD4 threshold of 500 cells/mm3. Methods. We performed a prospective study of CD4 variability in Malawian human immunodeficiency virus-infected, ART-naive, World Health Organization (WHO) stage 1 or 2, nonpregnant adults. CD4 counts were performed daily for 8 days. We fit a Bayesian linear mixed-effects model of log transformed CD4 cell counts to the data. We used Monte Carlo approximations to estimate misclassification rates for different observed values of CD4. The misclassification rate was calculated based on the conditional probability of true CD4 given the geometric mean of observed CD4 measurements. Results. Fifty patients were enrolled from 2 sites. The median age was 33.5 years (interquartile range, 27.5-40.0) and 34 (68%) were female. Misclassification rates were <1% when the observed CD4 counts were <=250 or >=750 cells/mm3. Rates of misclassification were high at observed CD4 counts between 350 and 650 cells/mm3, particularly when a single measurement was used (up to 46.7%). Conclusions. Our data show that ART eligibility based on a single CD4 count results in highest risk of misclassification when observed CD4 counts are in the range of 350-650 cells/mm3. Given the benefits of early ART, countries should weigh the costs and complexity of CD4 testing using a 500 cell/mm3 threshold against the cost savings and public health benefits of universal eligibility. PMID- 27704030 TI - Continued Sensitivity of Plasmodium falciparum to Artemisinin in Guyana, With Absence of Kelch Propeller Domain Mutant Alleles. AB - Because of concerns about possible emergence of artemisinin resistance strains of Plasmodium falciparum in mining areas of the interior of Guyana, a 7-day artesunate trial was conducted from March to December 2014. The day-3 parasite clearance rate, the efficacy of artesunate at day 28, and polymorphism of Kelch 13 (PfK13)-the marker of artemisinin resistance-were assessed. The study confirmed the continued sensitivity of P falciparum to artemisinin. A 7-day course of artesunate was 100% efficacious with only 2% (95% confidence interval, .1%-10.9%) of enrolled subjects positive at day 3. All day-0 parasite samples were wild type. Continued resistance monitoring is nevertheless recommended, given the widespread availability and uncontrolled use of artemisinin drugs in mining areas of Guyana. PMID- 27704029 TI - Risk Factors for Influenza A(H7N9) Disease in China, a Matched Case Control Study, October 2014 to April 2015. AB - Background. Human infections with avian influenza A(H7N9) virus have been associated with exposure to poultry and live poultry markets (LPMs). We conducted a case-control study to identify additional and more specific risk factors. Methods. Cases were laboratory-confirmed A(H7N9) infections in persons in China reported from October 1, 2014 to April 30, 2015. Poultry workers, those with insufficient data, and those refusing participation were excluded. We matched up to 4 controls per case by sex, age, and residential community. Using conditional logistic regression, we examined associations between A(H7N9) infection and potential risk factors. Results. Eighty-five cases and 334 controls were enrolled with similar demographic characteristics. Increased risk of A(H7N9) infection was associated with the following: visiting LPMs (adjusted odds ratio [aOR], 6.3; 95% confidence interval [CI], 2.6-15.3), direct contact with live poultry in LPMs (aOR, 4.1; 95% CI, 1.1-15.6), stopping at a live poultry stall when visiting LPMs (aOR, 2.7; 95% CI, 1.1-6.9), raising backyard poultry at home (aOR, 7.7; 95% CI, 2.0-30.5), direct contact with backyard poultry (aOR, 4.9; 95% CI, 1.1-22.1), and having >=1 chronic disease (aOR, 3.1; 95% CI, 1.5-6.5). Conclusions. Our study identified raising backyard poultry at home as a risk factor for illness with A(H7N9), suggesting the need for enhanced avian influenza surveillance in rural areas. PMID- 27704031 TI - Automatic selection of the active electrode set for image-guided cochlear implant programming. AB - Cochlear implants (CIs) are neural prostheses that restore hearing by stimulating auditory nerve pathways within the cochlea using an implanted electrode array. Research has shown when multiple electrodes stimulate the same nerve pathways, competing stimulation occurs and hearing outcomes decline. Recent clinical studies have indicated that hearing outcomes can be significantly improved by using an image-guided active electrode set selection technique we have designed, in which electrodes that cause competing stimulation are identified and deactivated. In tests done to date, an expert is needed to perform the electrode selection step with the assistance of a method to visualize the spatial relationship between electrodes and neural sites determined using image analysis techniques. We propose to automate the electrode selection step by optimizing a cost function that captures the heuristics used by the expert. Further, we propose an approach to estimate the values of parameters used in the cost function using an existing database of expert electrode selections. We test this method with different electrode array models from three manufacturers. Our automatic approach generates acceptable active electrode sets in 98.3% of the subjects tested. This approach represents a crucial step toward clinical translation of our image-guided CI programming system. PMID- 27704032 TI - Correlation between human detection accuracy and observer model-based image quality metrics in computed tomography. AB - The purpose of this study was to compare computed tomography (CT) low-contrast detectability from human readers with observer model-based surrogates of image quality. A phantom with a range of low-contrast signals (five contrasts, three sizes) was imaged on a state-of-the-art CT scanner (Siemens' force). Images were reconstructed using filtered back projection and advanced modeled iterative reconstruction and were assessed by 11 readers using a two alternative forced choice method. Concurrently, contrast-to-noise ratio (CNR), area-weighted CNR (CNRA), and observer model-based metrics were estimated, including nonprewhitening (NPW) matched filter, NPW with eye filter (NPWE), NPW with internal noise, NPW with an eye filter and internal noise (NPWEi), channelized Hotelling observer (CHO), and CHO with internal noise (CHOi). The correlation coefficients (Pearson and Spearman), linear discriminator error, [Formula: see text], and magnitude of confidence intervals, [Formula: see text], were used to determine correlation, proper characterization of the reconstruction algorithms, and model precision, respectively. Pearson (Spearman) correlation was 0.36 (0.33), 0.83 (0.84), 0.84 (0.86), 0.86 (0.88), 0.86 (0.91), 0.88 (0.90), 0.85 (0.89), and 0.87 (0.84), [Formula: see text] was 0.25, 0.15, 0.2, 0.25, 0.3, 0.25, 0.4, and 0.45, and [Formula: see text] was [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] for CNR, CNRA, NPW, NPWE, NPWi, NPWEi, CHO, and CHOi, respectively.

AB - We explore the InSb-semiconductor lattice dynamics after excitation of high density electron-hole plasma with an ultrashort and intense laser pulse. By using time resolved x-ray diffraction, a sub-mA and sub-ps resolution was achieved. Thus, a strain of 4% was measured in a 3 nm thin surface layer 2 ps after excitation. The lattice strain was observed for the first 5 ps as exponentially decaying, changing rapidly by time and by depth. The observed phenomena can only be understood assuming nonlinear time dependent laser absorption where the absorption depth decreases by a factor of twenty compared to linear absorption. PMID- 27704033 TI - Optical analysis of enamel and dentin caries in relation to mineral density using swept-source optical coherence tomography. AB - The aim of this study was to evaluate the signal intensity and signal attenuation of swept source optical coherence tomography (SS-OCT) for dental caries in relation to the variation of mineral density. SS-OCT observation was performed on the enamel and dentin artificial demineralization and on natural caries. The artificial caries model on enamel and dentin surfaces was created using Streptococcus mutans biofilms incubated in an oral biofilm reactor. The lesions were centrally cross sectioned and SS-OCT scans were obtained in two directions to construct a three-dimensional data set, from the lesion surface (sagittal scan) and parallel to the lesion surface (horizontal scan). The integrated signal up to [Formula: see text] in depth (IS200) and the attenuation coefficient ([Formula: see text]) of the enamel and dentin lesions were calculated from the SS-OCT signal in horizontal scans at five locations of lesion depth. The values were compared with the mineral density obtained from transverse microradiography. Both enamel and dentin demineralization showed significantly higher IS200 and [Formula: see text] than the sound tooth substrate from the sagittal scan. Enamel demineralization showed significantly higher IS200 than sound enamel, even with low levels of demineralization. In demineralized dentin, the [Formula: see text] from the horizontal scan consistently trended downward compared to the sound dentin. PMID- 27704035 TI - Time-of-flight electron energy loss spectroscopy using TM110 deflection cavities. AB - We demonstrate the use of two TM110 resonant cavities to generate ultrashort electron pulses and subsequently measure electron energy losses in a time-of flight type of setup. The method utilizes two synchronized microwave cavities separated by a drift space of 1.45 m. The setup has an energy resolution of 12 +/ 2 eV FWHM at 30 keV, with an upper limit for the temporal resolution of 2.7 +/- 0.4 ps. Both the time and energy resolution are currently limited by the brightness of the tungsten filament electron gun used. Through simulations, it is shown that an energy resolution of 0.95 eV and a temporal resolution of 110 fs can be achieved using an electron gun with a higher brightness. With this, a new method is provided for time-resolved electron spectroscopy without the need for elaborate laser setups or expensive magnetic spectrometers. PMID- 27704036 TI - Treatment of spontaneous EAE by laquinimod reduces Tfh, B cell aggregates, and disease progression. AB - OBJECTIVE: To evaluate the influence of oral laquinimod, a candidate multiple sclerosis (MS) treatment, on induction of T follicular helper cells, development of meningeal B cell aggregates, and clinical disease in a spontaneous B cell dependent MS model. METHODS: Experimental autoimmune encephalomyelitis (EAE) was induced in C57BL/6 mice by immunization with recombinant myelin oligodendrocyte glycoprotein (rMOG) protein. Spontaneous EAE was evaluated in C57BL/6 MOG p35-55 specific T cell receptor transgenic (2D2) * MOG-specific immunoglobulin (Ig)H chain knock-in (IgHMOG-ki [Th]) mice. Laquinimod was administered orally. T cell and B cell populations were examined by flow cytometry and immunohistochemistry. RESULTS: Oral laquinimod treatment (1) reduced CD11c+CD4+ dendritic cells, (2) inhibited expansion of PD-1+CXCR5+BCL6+ T follicular helper and interleukin (IL) 21-producing activated CD4+CD44+ T cells, (3) suppressed B cell CD40 expression, (4) diminished formation of Fas+GL7+ germinal center B cells, and (5) inhibited development of MOG-specific IgG. Laquinimod treatment not only prevented rMOG induced EAE, but also inhibited development of spontaneous EAE and the formation of meningeal B cell aggregates. Disability progression was prevented when laquinimod treatment was initiated after mice developed paralysis. Treatment of spontaneous EAE with laquinimod was also associated with increases in CD4+CD25hiFoxp3+ and CD4+CD25+IL-10+ regulatory T cells. CONCLUSIONS: Our observations that laquinimod modulates myelin antigen-specific B cell immune responses and suppresses both development of meningeal B cell aggregates and disability progression in spontaneous EAE should provide insight regarding the potential application of laquinimod to MS treatment. Results of this investigation demonstrate how the 2D2 * Th spontaneous EAE model can be used successfully for preclinical evaluation of a candidate MS treatment.

PMID- 27704039 TI - A Prospective Observational Cohort Study on Orthopaedic and Anaesthetic Registrars Performing Femoral Nerve Block on Patients with an Acute Hip Fracture. AB - We investigated if a femoral nerve block (FNB) for patients with a proximal femoral fracture (PFF) and administered by an orthopaedic registrar (OR) instead of an anaesthesiology registrar (AR) lowers the lead time to block and reduces the total amount of rescue analgesics during the preoperative phase. 205 patients were included in a prospective observational cohort study. The main outcome variable was rescue analgesics as total intravenous morphine prior to surgery. All results were adjusted for confounding using age, sex, cognitive dysfunction, and ASA classification. The OR group (n = 135) was over 2 hours faster in performing the block compared to the AR group (n = 70) but was nonetheless correlated with an increased amount of rescue analgesics during the study, 2.4 mg morphine (95% CI 0.0-4.9) more compared to the AR group. We found no difference between the groups in the risk of adverse events. We conclude that, for patients with an acute PFF and with morphine consumption as end point, how soon from arrival to hospital the patients receive a FNB is of lesser importance than who is administering it. Based on our results we recommend that emergency hospitals should have routines for anaesthesiologists performing FNB on this frail patient group. PMID- 27704040 TI - Universal microbial diagnostics using random DNA probes. AB - Early identification of pathogens is essential for limiting development of therapy-resistant pathogens and mitigating infectious disease outbreaks. Most bacterial detection schemes use target-specific probes to differentiate pathogen species, creating time and cost inefficiencies in identifying newly discovered organisms. We present a novel universal microbial diagnostics (UMD) platform to screen for microbial organisms in an infectious sample, using a small number of random DNA probes that are agnostic to the target DNA sequences. Our platform leverages the theory of sparse signal recovery (compressive sensing) to identify the composition of a microbial sample that potentially contains novel or mutant species. We validated the UMD platform in vitro using five random probes to recover 11 pathogenic bacteria. We further demonstrated in silico that UMD can be generalized to screen for common human pathogens in different taxonomy levels. UMD's unorthodox sensing approach opens the door to more efficient and universal molecular diagnostics. PMID- 27704042 TI - Not spreading in reverse: The dewetting of a liquid film into a single drop. AB - Wetting and dewetting are both fundamental modes of motion of liquids on solid surfaces. They are critically important for processes in biology, chemistry, and engineering, such as drying, coating, and lubrication. However, recent progress in wetting, which has led to new fields such as superhydrophobicity and liquid marbles, has not been matched by dewetting. A significant problem has been the inability to study the model system of a uniform film dewetting from a nonwetting surface to a single macroscopic droplet-a barrier that does not exist for the reverse wetting process of a droplet spreading into a film. We report the dewetting of a dielectrophoresis-induced film into a single equilibrium droplet. The emergent picture of the full dewetting dynamics is of an initial regime, where a liquid rim recedes at constant speed and constant dynamic contact angle, followed by a relatively short exponential relaxation of a spherical cap shape. This sharply contrasts with the reverse wetting process, where a spreading droplet follows a smooth sequence of spherical cap shapes. Complementary numerical simulations and a hydrodynamic model reveal a local dewetting mechanism driven by the equilibrium contact angle, where contact line slip dominates the dewetting dynamics. Our conclusions can be used to understand a wide variety of processes involving liquid dewetting, such as drop rebound, condensation, and evaporation. In overcoming the barrier to studying single film-to-droplet dewetting, our results provide new approaches to fluid manipulation and uses of dewetting, such as inducing films of prescribed initial shapes and slip controlled liquid retraction.

AB - Chemical contrast has long been sought for label-free visualization of biomolecules and materials in complex living systems. Although infrared spectroscopic imaging has come a long way in this direction, it is thus far only applicable to dried tissues because of the strong infrared absorption by water. It also suffers from low spatial resolution due to long wavelengths and lacks optical sectioning capabilities. We overcome these limitations through sensing vibrational absorption-induced photothermal effect by a visible laser beam. Our mid-infrared photothermal (MIP) approach reached 10 MUM detection sensitivity and submicrometer lateral spatial resolution. This performance has exceeded the diffraction limit of infrared microscopy and allowed label-free three-dimensional chemical imaging of live cells and organisms. Distributions of endogenous lipid and exogenous drug inside single cells were visualized. We further demonstrated in vivo MIP imaging of lipids and proteins in Caenorhabditis elegans. The reported MIP imaging technology promises broad applications from monitoring metabolic activities to high-resolution mapping of drug molecules in living systems, which are beyond the reach of current infrared microscopy.

AB - We describe a cryo-electron microscopy three-dimensional image reconstruction of relaxed myosin II-containing thick filaments from the flight muscle of the giant water bug Lethocerus indicus. The relaxed thick filament structure is a key element of muscle physiology because it facilitates the reextension process following contraction. Conversely, the myosin heads must disrupt their relaxed arrangement to drive contraction. Previous models predicted that Lethocerus myosin was unique in having an intermolecular head-head interaction, as opposed to the intramolecular head-head interaction observed in all other species. In contrast to the predicted model, we find an intramolecular head-head interaction, which is similar to that of other thick filaments but oriented in a distinctly different way. The arrangement of myosin's long alpha-helical coiled-coil rod domain has been hypothesized as either curved layers or helical subfilaments. Our reconstruction is the first report having sufficient resolution to track the rod alpha helices in their native environment at resolutions ~5.5 A, and it shows that the layer arrangement is correct for Lethocerus. Threading separate paths through the forest of myosin coiled coils are four nonmyosin peptides. We suggest that the unusual position of the heads and the rod arrangement separated by nonmyosin peptides are adaptations for mechanical signal transduction whereby applied tension disrupts the myosin heads as a component of stretch activation. PMID- 27704044 TI - Giant facet-dependent spin-orbit torque and spin Hall conductivity in the triangular antiferromagnet IrMn3. AB - There has been considerable interest in spin-orbit torques for the purpose of manipulating the magnetization of ferromagnetic elements for spintronic technologies. Spin-orbit torques are derived from spin currents created from charge currents in materials with significant spin-orbit coupling that propagate into an adjacent ferromagnetic material. A key challenge is to identify materials that exhibit large spin Hall angles, that is, efficient charge-to-spin current conversion. Using spin torque ferromagnetic resonance, we report the observation of a giant spin Hall angle [Formula: see text] of up to ~0.35 in (001)-oriented single-crystalline antiferromagnetic IrMn3 thin films, coupled to ferromagnetic permalloy layers, and a [Formula: see text] that is about three times smaller in (111)-oriented films. For (001)-oriented samples, we show that the magnitude of [Formula: see text] can be significantly changed by manipulating the populations of various antiferromagnetic domains through perpendicular field annealing. We identify two distinct mechanisms that contribute to [Formula: see text]: the first mechanism, which is facet-independent, arises from conventional bulk spin dependent scattering within the IrMn3 layer, and the second intrinsic mechanism is derived from the unconventional antiferromagnetic structure of IrMn3. Using ab initio calculations, we show that the triangular magnetic structure of IrMn3 gives rise to a substantial intrinsic spin Hall conductivity that is much larger for the (001) than for the (111) orientation, consistent with our experimental findings. PMID- 27704045 TI - Satellite tidal magnetic signals constrain oceanic lithosphere-asthenosphere boundary. AB - The tidal flow of electrically conductive oceans through the geomagnetic field results in the generation of secondary magnetic signals, which provide information on the subsurface structure. Data from the new generation of satellites were shown to contain magnetic signals due to tidal flow; however, there are no reports that these signals have been used to infer subsurface structure. We use satellite-detected tidal magnetic fields to image the global electrical structure of the oceanic lithosphere and upper mantle down to a depth of about 250 km. The model derived from more than 12 years of satellite data reveals a ~72-km-thick upper resistive layer followed by a sharp increase in electrical conductivity likely associated with the lithosphere-asthenosphere boundary, which separates colder rigid oceanic plates from the ductile and hotter asthenosphere. PMID- 27704046 TI - Energy gap evolution across the superconductivity dome in single crystals of (Ba1 x K x )Fe2As2. AB - The mechanism of unconventional superconductivity in iron-based superconductors (IBSs) is one of the most intriguing questions in current materials research. Among non-oxide IBSs, (Ba1-x K x )Fe2As2 has been intensively studied because of its high superconducting transition temperature and fascinating evolution of the superconducting gap structure from being fully isotropic at optimal doping (x ~ 0.4) to becoming nodal at x > 0.8. Although this marked evolution was identified in several independent experiments, there are no details of the gap evolution to date because of the lack of high-quality single crystals covering the entire K doping range of the superconducting dome. We conducted a systematic study of the London penetration depth, lambda(T), across the full phase diagram for different concentrations of point-like defects introduced by 2.5-MeV electron irradiation. Fitting the low-temperature variation with the power law, Deltalambda ~ Tn , we find that the exponent n is the highest and the Tc suppression rate with disorder is the smallest at optimal doping, and they evolve with doping being away from optimal, which is consistent with increasing gap anisotropy, including an abrupt change around x ? 0.8, indicating the onset of nodal behavior. Our analysis using a self-consistent t-matrix approach suggests the ubiquitous and robust nature of s+/- pairing in IBSs and argues against a previously suggested transition to a d wave state near x = 1 in this system. PMID- 27704047 TI - Microbial synthesis of highly dispersed PdAu alloy for enhanced electrocatalysis. AB - Biosynthesis based on the reducing capacity of electrochemically active bacteria is frequently used in the reduction of metal ions into nanoparticles as an eco friendly way to recycle metal resources. However, those bionanoparticles cannot be used directly as electrocatalysts because of the poor conductivity of cell substrates. This problem was solved by a hydrothermal reaction, which also contributes to the heteroatom doping and alloying between Pd and Au. With the protection of graphene, the aggregation of nanoparticles was successfully avoided, and the porous structure was maintained, resulting in better electrocatalytic activity and durability than commercial Pd/C under both alkaline (CH3CH2OH, 6.15-fold of mass activity) and acidic (HCOOH, 6.58-fold of mass activity) conditions. The strategy developed in this work opens up a horizon into designing electrocatalysts through fully utilizing the abundant resources in nature. PMID- 27704048 TI - The local spiral structure of the Milky Way. AB - The nature of the spiral structure of the Milky Way has long been debated. Only in the last decade have astronomers been able to accurately measure distances to a substantial number of high-mass star-forming regions, the classic tracers of spiral structure in galaxies. We report distance measurements at radio wavelengths using the Very Long Baseline Array for eight regions of massive star formation near the Local spiral arm of the Milky Way. Combined with previous measurements, these observations reveal that the Local Arm is larger than previously thought, and both its pitch angle and star formation rate are comparable to those of the Galaxy's major spiral arms, such as Sagittarius and Perseus. Toward the constellation Cygnus, sources in the Local Arm extend for a great distance along our line of sight and roughly along the solar orbit. Because of this orientation, these sources cluster both on the sky and in velocity to form the complex and long enigmatic Cygnus X region. We also identify a spur that branches between the Local and Sagittarius spiral arms. PMID- 27704049 TI - Evolution of anatase surface active sites probed by in situ sum-frequency phonon spectroscopy. AB - Surface active sites of crystals often govern their relevant surface chemistry, yet to monitor them in situ in real atmosphere remains a challenge. Using surface specific sum-frequency spectroscopy, we identified the surface phonon mode associated with the active sites of undercoordinated titanium ions and conjoint oxygen vacancies, and used it to monitor them on anatase (TiO2) (101) under ambient conditions. In conjunction with theory, we determined related surface structure around the active sites and tracked the evolution of oxygen vacancies under ultraviolet irradiation. We further found that unlike in vacuum, the surface oxygen vacancies, which dominate the surface reactivity, are strongly regulated by ambient gas molecules, including methanol and water, as well as weakly associated species, such as nitrogen and hydrogen. The result revealed a rich interplay between prevailing ambient species and surface reactivity, which can be omnipresent in environmental and catalytic applications of titanium dioxides. PMID- 27704051 TI - Rescue of the 1947 Zika Virus Prototype Strain with a Cytomegalovirus Promoter Driven cDNA Clone. AB - The recent Zika virus (ZIKV) outbreak has been linked to severe pathogenesis. Here, we report the construction of a plasmid carrying a cytomegalovirus (CMV) promoter-expressed prototype 1947 Uganda MR766 ZIKV cDNA that can initiate infection following direct plasmid DNA transfection of mammalian cells. Incorporation of a synthetic intron in the nonstructural protein 1 (NS1) region of the ZIKV polyprotein reduced viral cDNA-associated toxicity in bacteria. High levels of infectious virus were produced following transfection of the plasmid bearing the wild-type MR766 ZIKV genome, but not one with a disruption to the viral nonstructural protein 5 (NS5) polymerase active site. Multicycle growth curve and plaque assay experiments indicated that the MR766 virus resulting from plasmid transfection exhibited growth characteristics that were more similar to its parental isolate than previously published 2010 Cambodia and 2015 Brazil cDNA rescued ZIKV. This ZIKV infectious clone will be useful for investigating the genetic determinants of ZIKV infection and pathogenesis and should be amenable to construction of diverse infectious clones expressing reporter proteins and representing a range of ZIKV isolates. IMPORTANCE The study of ZIKV, which has become increasingly important with the recent association of this virus with microcephaly and Guillain-Barre syndrome, would benefit from an efficient strategy to genetically manipulate the virus. This work describes a model system to produce infectious virus in cell culture. We created a plasmid carrying the prototype 1947 Uganda MR766 ZIKV genome that both was stable in bacteria and could produce high levels of infectious virus in mammalian cells through direct delivery of this DNA. Furthermore, growth properties of this rescued virus closely resembled those of the viral isolate from which it was derived. This model system will provide a simple and effective means to study how ZIKV genetics impact viral replication and pathogenesis. PMID- 27704052 TI - Different Regulations of ROM2 and LRG1 Expression by Ccr4, Pop2, and Dhh1 in the Saccharomyces cerevisiae Cell Wall Integrity Pathway. AB - Ccr4, a component of the Ccr4-Not cytoplasmic deadenylase complex, is known to be required for the cell wall integrity (CWI) pathway in the budding yeast Saccharomyces cerevisiae. However, it is not fully understood how Ccr4 and other components of the Ccr4-Not complex regulate the CWI pathway. Previously, we showed that Ccr4 functions in the CWI pathway together with Khd1 RNA binding protein. Ccr4 and Khd1 modulate a signal from Rho1 small GTPase in the CWI pathway by regulating the expression of ROM2 mRNA and LRG1 mRNA, encoding a guanine nucleotide exchange factor (GEF) and a GTPase-activating protein (GAP) for Rho1, respectively. Here we examined the possible involvement of the POP2 gene encoding a subunit of the Ccr4-Not complex and the DHH1 gene encoding a DEAD box RNA helicase that associates with the Ccr4-Not complex in the regulation of ROM2 and LRG1 expression. Neither ROM2 mRNA level nor Rom2 function was impaired by pop2Delta or dhh1Delta mutation. The LRG1 mRNA level was increased in pop2Delta and dhh1Delta mutants, as well as the ccr4Delta mutant, and the growth defects caused by pop2Delta and dhh1Delta mutations were suppressed by lrg1Delta mutation. Our results suggest that LRG1 expression is regulated by Ccr4 together with Pop2 and Dhh1 and that ROM2 expression is regulated by Khd1 and Ccr4, but not by Pop2 and Dhh1. Thus, Rho1 activity in the CWI pathway is precisely controlled by modulation of the mRNA levels for Rho1-GEF Rom2 and Rho1-GAP Lrg1. IMPORTANCE We find here that Ccr4, Pop2, and Dhh1 modulate the levels of mRNAs for specific Rho1 regulators, Rom2 and Lrg1. In budding yeast, Rho1 activity is tightly regulated both temporally and spatially. It is anticipated that Ccr4, Pop2, and Dhh1 may contribute to the precise spatiotemporal control of Rho1 activity by regulating expression of its regulators temporally and spatially. Our finding on the roles of the components of the Ccr4-Not complex in yeast would give important information for understanding the roles of the evolutionary conserved Ccr4-Not complex. PMID- 27704050 TI - Genome Diversity, Recombination, and Virulence across the Major Lineages of Paracoccidioides. AB - The Paracoccidioides genus includes two species of thermally dimorphic fungi that cause paracoccidioidomycosis, a neglected health-threatening human systemic mycosis endemic to Latin America. To examine the genome evolution and the diversity of Paracoccidioides spp., we conducted whole-genome sequencing of 31 isolates representing the phylogenetic, geographic, and ecological breadth of the genus. These samples included clinical, environmental and laboratory reference strains of the S1, PS2, PS3, and PS4 lineages of P. brasiliensis and also isolates of Paracoccidioides lutzii species. We completed the first annotated genome assemblies for the PS3 and PS4 lineages and found that gene order was highly conserved across the major lineages, with only a few chromosomal rearrangements. Comparing whole-genome assemblies of the major lineages with single-nucleotide polymorphisms (SNPs) predicted from the remaining 26 isolates, we identified a deep split of the S1 lineage into two clades we named S1a and S1b. We found evidence for greater genetic exchange between the S1b lineage and all other lineages; this may reflect the broad geographic range of S1b, which is often sympatric with the remaining, largely geographically isolated lineages. In addition, we found evidence of positive selection for the GP43 and PGA1 antigen genes and genes coding for other secreted proteins and proteases and lineage specific loss-of-function mutations in cell wall and protease genes; these together may contribute to virulence and host immune response variation among natural isolates of Paracoccidioides spp. These insights into the recent evolutionary events highlight important differences between the lineages that could impact the distribution, pathogenicity, and ecology of Paracoccidioides. IMPORTANCE Characterization of genetic differences between lineages of the dimorphic human-pathogenic fungus Paracoccidioides can identify changes linked to important phenotypes and guide the development of new diagnostics and treatments. In this article, we compared genomes of 31 diverse isolates representing the major lineages of Paracoccidioides spp. and completed the first annotated genome sequences for the PS3 and PS4 lineages. We analyzed the population structure and characterized the genetic diversity among the lineages of Paracoccidioides, including a deep split of S1 into two lineages (S1a and S1b), and differentiated S1b, associated with most clinical cases, as the more highly recombining and diverse lineage. In addition, we found patterns of positive selection in surface proteins and secreted enzymes among the lineages, suggesting diversifying mechanisms of pathogenicity and adaptation across this species complex. These genetic differences suggest associations with the geographic range, pathogenicity, and ecological niches of Paracoccidioides lineages. PMID- 27704053 TI - Divergent Isoprenoid Biosynthesis Pathways in Staphylococcus Species Constitute a Drug Target for Treating Infections in Companion Animals. AB - Staphylococcus species are a leading cause of skin and soft tissue infections in humans and animals, and the antibiotics used to treat these infections are often the same. Methicillin- and multidrug-resistant staphylococcal infections are becoming more common in human and veterinary medicine. From a "One Health" perspective, this overlap in antibiotic use and resistance raises concerns over the potential spread of antibiotic resistance genes. Whole-genome sequencing and comparative genomics analysis revealed that Staphylococcus species use divergent pathways to synthesize isoprenoids. Species frequently associated with skin and soft tissue infections in companion animals, including S. schleiferi and S. pseudintermedius, use the nonmevalonate pathway. In contrast, S. aureus, S. epidermidis, and S. lugdunensis use the mevalonate pathway. The antibiotic fosmidomycin, an inhibitor of the nonmevalonate pathway, was effective in killing canine clinical staphylococcal isolates but had no effect on the growth or survival of S. aureus and S. epidermidis. These data identify an essential metabolic pathway in Staphylococcus that differs among members of this genus and suggest that drugs such as fosmidomycin, which targets enzymes in the nonmevalonate pathway, may be an effective treatment for certain staphylococcal infections. IMPORTANCE Drug-resistant Staphylococcus species are a major concern in human and veterinary medicine. There is a need for new antibiotics that exhibit a selective effect in treating infections in companion and livestock animals and that would not be used to treat human bacterial infections. We have identified fosmidomycin as an antibiotic that selectively targets certain Staphylococcus species that are often encountered in skin infections in cats and dogs. These findings expand our understanding of Staphylococcus evolution and may have direct implications for treating staphylococcal infections in veterinary medicine. PMID- 27704054 TI - Renal Vein Injury During Percutaneous Nephrolithotomy Procedure. AB - Background: Percutaneous nephrostolithotomy is an important approach for removing kidney stones. Puncturing and dilatation are two mandatory steps in percutaneous nephrolithotomy (PCNL). Uncommonly, during dilatation, the dilators can cause direct injury to the main renal vein or to their tributaries. Case Presentation: A 75-year-old female underwent PCNL for partial staghorn stone in the left kidney. During puncturing and dilatation, renal vein tributary was injured, and the nephroscope entered the renal vein and inferior vena cava, which was clearly recognized. Injection of contrast material through the nephroscope confirms the false pathway to the great veins (renal vein and inferior vena cava). Bleeding was controlled intraoperatively by applying Amplatz sheath over the abnormal tract, the procedure was continued and stones were removed. At the end of the procedure, a Foley catheter was used as a nephrostomy tube and its balloon was inflated inside the renal pelvis and pulled back with light pressure to the lower calix, which was the site of injury to the renal vein tributaries, then the nephrostomy tube was closed; by this we effectively controlled the bleeding. The patient remained hemodynamically stable; antegrade pyelography was done on the second postoperative day, there was distally patent ureter with no extravasation, neither contrast leak to renal vein, and was discharged home at third postoperative day. After 2 weeks, the nephrostomy tube was gradually removed in the operative room, without bleeding, on the next day, Double-J stent was removed. Conclusion: Direct injury and false tract to the renal vein tributaries during PCNL can result in massive hemorrhage, and can be treated conservatively in hemodynamically stable patients, using a nephrostomy catheter as a tamponade. PMID- 27704055 TI - Percutaneous Management of Systemic Fungal Infection Presenting As Bilateral Renal Fungal Ball. AB - Background: Zygomycoses are uncommon, frequently fatal diseases caused by fungi of the class Zygomycetes. The majority of human cases are caused by Mucorales (genus-rhizopus, mucor, and absidia) fungi. Renal involvement is uncommon and urine microscopy, pottasium hydroxide mount, and fungal cultures are frequently negative. Case Presentation: A twenty-one-year-old young unmarried lady presented to our emergency department with bilateral flank pain, fever, nausea, and decreased urine output of one-month duration. She was found to have azotemia with sepsis with bilateral hydronephrosis with a left renal pelvic obstructing stone. Even after nephrostomy drainage and broad spectrum antibiotics, her condition worsened. She developed disseminated fungal infection, and timely systemic antifungal followed by bilateral nephroscopic clearance saved the patient. Conclusion: Although renal fungal infections are uncommon, a high index of suspicion and early antifungal and surgical intervention can give favorable outcomes. PMID- 27704056 TI - Endoureteral Management of Renal Graft Ureteral Stenosis by the Use of Long-Term Metal Stent: An Appealing Treatment Option. AB - Background: Ureteral stenosis is part of the common complications of renal graft reported in 3% to 7% of cases. Multiple treatments have been introduced regarding length and position of the stenosis. Metal stents for urologic purpose were created in 1998. Double percutaneous antegrade and transurethral retrograde access to a ureteral stenosis to a long-term metal stent procedure has been rarely described. Case Presentation: Here, we present a case of a ureteral stricture in a double ipsilateral kidney graft with a common ureter. A 67-year old patient presented with obstructive nephritis associated with acute renal failure 6 years after a double renal graft with a uretero-ureteral end-to-side anastomosis. Abdominal CT scan showed double pelvic dilation. The patient underwent double percutaneous nephrostomies and antegrade pyelogram showed both renal pelvic and ureter dilations caused by a severe chronic ureteral stenosis at junction into the bladder. A Double-J ureteric stent was then inserted retrogradely over a guidewire as first-line treatment. Due to recurrent urinary tract infections (UTIs), removal and replacement of Double-J stents were carried out by placing a thermoexpandable metal stent Memokath(r) 051 (Bard, Pnn Medical) through the common ureter by a double antegrade and retrograde approach. Treatment was effective with a good renal function maintained after a 3-year follow-up without UTIs. Conclusion: Double antegrade and retrograde access to a long-term metal stent treatment can be seen as an alternative treatment to either endoscopy or open surgery. Further studies should be continued using larger series. PMID- 27704057 TI - Sulfadiazine-Induced Obstructive Nephropathy Presenting with Upper Urinary Tract Extravasation. AB - Background: Obstructive nephropathy is an uncommon side effect of sulfadiazine, which is used for the treatment of toxoplasmosis. We present a case of acute renal colic and urine extravasation of a patient shortly after she was started on this medication. Case Presentation: A 31-year-old female presented with acute renal colic 2 weeks after starting treatment with sulfadiazine and pyrimethamine for ocular toxoplasmosis. Results: A noncontrast computed tomography revealed left hydronephrosis and fluid located around the kidney and in the left gutter. There were no urinary stones. Administration of intravenous contrast revealed significant urine extravasation at the level of the ureteropelvic junction. Intravenous contrast injection confirmed that the extravasation consisted of urine leakage at the ureteropelvic junction. Her clinical condition improved with the insertion of an internal stent, which was left in place for 4 weeks. A retrograde pyelography performed at the time of the internal stent removal ruled out persistent extravasation and filling defects in the left upper urinary tract. Considering the clinical circumstances and the imaging results, it appears that this is a first reported case of sulfadiazine-induced obstructive uropathy associated with urine extravasation. Conclusion: Although rare, obstructive uropathy related to sulfadiazine medication should be promptly suspected, diagnosed, and treated. Patients should be instructed to substantially increase their liquid intake while on that medication. PMID- 27704058 TI - Arabidopsis thaliana microRNA162 level is posttranscriptionally regulated via splicing and polyadenylation site selection. AB - Arabidopsis microRNA162 (miRNA162) level regulation was studied under abiotic stresses, such as drought and salinity. The TaqMan(r) microRNA assay proved that A. thaliana miRNA162 level was elevated under these stresses, confirming its salt and drought responsiveness. The promoter region analyses of A. thaliana miRNA162a and b genes (MIR162a and MIR162b) identified numerous salinity and drought responsive elements. However, our results indicated that Arabidopsis MIR162a was presumably the main locus responsible for the mature ath-miRNA162 accumulation under the stresses tested, and the MIR162b was generally rather weakly expressed, both in control and under the stress conditions. The MIR162a structure was confirmed to be complex and the pri-miRNA162a hairpin structure was shown to span an alternative exon and an intron. The MIR162a transcription generated a few pri miRNA162a splicing isoforms that could be functional and non-functional. Upon drought and salinity stresses, the regulation of the pri-miRNA162a alternative splicing pattern revealed an increase of a functional pri-miR162a isoform and a preferential distal polyA site selection under the stress conditions. Apart from the potential transcriptional regulation of the miRNA genes (MIRs) expression, the data obtained point to an essential role of posttranscriptional regulation of Arabidopsis microRNA162 level. PMID- 27704059 TI - Inorganic perovskite photocatalysts for solar energy utilization. AB - The development and utilization of solar energy in environmental remediation and water splitting is being intensively studied worldwide. During the past few decades, tremendous efforts have been devoted to developing non-toxic, low-cost, efficient and stable photocatalysts for water splitting and environmental remediation. To date, several hundreds of photocatalysts mainly based on metal oxides, sulfides and (oxy)nitrides with different structures and compositions have been reported. Among them, perovskite oxides and their derivatives (layered perovskite oxides) comprise a large family of semiconductor photocatalysts because of their structural simplicity and flexibility. This review specifically focuses on the general background of perovskite and its related materials, summarizes the recent development of perovskite photocatalysts and their applications in water splitting and environmental remediation, discusses the theoretical modelling and calculation of perovskite photocatalysts and presents the key challenges and perspectives on the research of perovskite photocatalysts. PMID- 27704060 TI - Tuning two-dimensional nanomaterials by intercalation: materials, properties and applications. AB - 2D materials have attracted tremendous attention due to their unique physical and chemical properties since the discovery of graphene. Despite these intrinsic properties, various modification methods have been applied to 2D materials that yield even more exciting results in terms of tunable properties and device performance. Among all modification methods, intercalation of 2D materials has emerged as a particularly powerful tool: it provides the highest possible doping level and is capable of (ir)reversibly changing the phase of the material. Intercalated 2D materials exhibit extraordinary electrical transport as well as optical, thermal, magnetic, and catalytic properties, which are advantageous for optoelectronics, superconductors, thermoelectronics, catalysis and energy storage applications. The recent progress on host 2D materials, various intercalation species, and intercalation methods, as well as tunable properties and potential applications enabled by intercalation, are comprehensively reviewed. PMID- 27704061 TI - Theoretical prediction of coordination environments and stability constants of lanthanum lactate complexes in solution. AB - Using Density Functional Theory calculations in combination with explicit solvent and a continuum solvent model, this work sets out to understand the coordination environment and relevant thermodynamics of La(iii)-lactate complexes. Calculations focus on the coordination modes for the complexes and changes in Gibbs free energy for complexation in solution. These results confirm that the alpha-hydroxyl group should be protonated, or at least hydrogen bonded to a water molecule, upon successive addition of the lactate ligand to the La(iii) center using Bader's Atoms-in Molecules (AIM) approach. In addition, we present a straightforward method for predicting stability constants at the semi quantitative level for La(iii)-lactate complexes in solution. The proposed method could be particularly useful for prediction of lanthanide complex formation in various biochemical, environmental, and nuclear separations processes. PMID- 27704066 TI - The potential beneficial effects of phenolic compounds isolated from A. pilosa Ledeb on insulin-resistant hepatic HepG2 cells. AB - Agrimonia pilosa Ledeb (AP) has already been applied in practice for the treatment of different disorders and is available to access without the provision of a medical prescription. The present study aims at investigating the effect of bioactive compounds isolated from AP on the improvement of insulin resistance, figuring out the mechanism in insulin-responsive cell lines. Five compounds were isolated from AP using column chromatography, including agrimonolide (K1), desmethylagrimonolide (K2), tormentic acid (K3), ursolic acid (K4), and quercetin (K5). Glucose metabolism was evaluated in insulin-resistant HepG2 cells. Ursolic acid had the strongest activity among all isolated compounds with the lowering value of 71.5% (1.24 mM glucose in DMEM) and 71.7% (1.23 mM) when compared to the control. K1 consisting of K2 effectively increased the insulin-mediated glycogen level in hepatocytes. At a concentration level of 20 MUM, K2 significantly elevated the hepatic glucokinase (GK) activity (3.2 U min-1 mg-1 protein), followed by K1 (3.0 U min-1 mg-1 protein). Both of them significantly increased (p < 0.05) the GK activity as compared to the control. On the same lines, K2 and K1 caused a significant reduction of the glucose-6-phosphatase (G6Pase) activity and a significant change in the phosphoenolpyruvate carboxykinase (PEPCK) activity. In summary, bioactive compounds in AP may play an important role in regulating the glucose metabolism in insulin-resistant HepG2 cells and could be developed as a promising natural material for diabetes prevention and treatment. PMID- 27704067 TI - Mid-infrared fibre evanescent wave spectroscopy of serum allows fingerprinting of the hepatic metabolic status in mice. AB - Non-alcoholic fatty liver disease is associated with obesity, diabetes, and metabolic syndrome. The detection of systemic metabolic changes associated with alterations in the liver status during non-alcoholic fatty liver disease could improve patient follow-up. The aim of the present study was to evaluate the potential of mid-infrared fibre evanescent wave spectroscopy as a minimum invasive method for evaluating the liver status during non-alcoholic fatty liver disease. Seventy-five mice were subjected to a control, high-fat or high-fat-high carbohydrate diets. We analysed the serum biochemical parameters and mRNA levels of hepatic genes by quantitative RT-PCR. Steatosis was quantified by image analysis. The mid-infrared spectra were acquired from serum, and then analysed to develop a predictive model of the steatosis level. Animals subjected to enriched diets were obese. Hepatic steatosis was found in all animals. The relationship between the spectroscopy-predicted and observed levels of steatosis, expressed as percentages of the liver biopsy area, was not linear. A transition around 10% steatosis was observed, leading us to consider two distinct predictive models (<10% and >10%) based on two different sets of discriminative spectral variables. The model performance was evaluated using random cross-validation (10%). The hypothesis that additional metabolic changes occur beyond this transition was supported by the fact that it was associated with increased serum ALT levels, and Col1alpha1 chain mRNA levels. Our data suggest that mid-infrared spectroscopy combined with statistical analysis allows identifying serum mid-infrared signatures that reflect the liver status during non-alcoholic fatty liver disease. PMID- 27704068 TI - Recent developments in polydopamine: an emerging soft matter for surface modification and biomedical applications. AB - After more than four billion years of evolution, nature has created a large number of fascinating living organisms, which show numerous peculiar structures and wonderful properties. Nature can provide sources of plentiful inspiration for scientists to create various materials and devices with special functions and uses. Since Messersmith proposed the fabrication of multifunctional coatings through mussel-inspired chemistry, this field has attracted considerable attention for its promising and exiciting applications. Polydopamine (PDA), an emerging soft matter, has been demonstrated to be a crucial component in mussel inspired chemistry. In this review, the recent developments of PDA for mussel inspired surface modification are summarized and discussed. The biomedical applications of PDA-based materials are also highlighted. We believe that this review can provide important and timely information regarding mussel-inspired chemistry and will be of great interest for scientists in the chemistry, materials, biology, medicine and interdisciplinary fields. PMID- 27704070 TI - Sensitive fluorescence detection of mercury(ii) in aqueous solution by the fluorescence quenching effect of MoS2 with DNA functionalized carbon dots. AB - A rapid and sensitive fluorescent sensor based on the MoS2 nanosheet/DNA/carbon dot nanoassembly has been developed towards the detection of mercury(ii) present in environmental samples. Bio-carbon dots (CDs) having strong fluorescence maxima at 451 nm were synthesized via one-step treatment with honey under low temperature carbonization. These CDs were nearly spherical with good size distribution and excellent monodispersity, and the average sizes of CD were around 2-4 nm as evidenced from transmission electron microscopy. The conjugation of DNA strands on the surface of the carbon dots provided an efficient fluorescent probe. The fluorescence of the MoS2 nanosheet/DNA/carbon dot nanoassembly enhanced gradually with the increase in the concentration of Hg2+ ions and the detection limit was found to be 1.02 nM. Furthermore, the fluorescence intensity was found to be linear with the concentration of Hg2+ ions in the range from 0 to 10 nM and their respective coefficient of determination was found to be 0.93676 and 0.98178.

AB - Using microscopy and image analysis, we characterize binding of filamentous viral nanoparticles to a fibrous affinity matrix as models for reporter capture in a lateral flow assay (LFA). M13 bacteriophage (M13) displaying an in vivo biotinylated peptide (AviTag) genetically fused to the M13 tail protein p3 are functionalized with fluorescent labels. We functionalize glass fiber LFA membranes with antibodies to M13, which primarily capture M13 on the major p8 coat proteins, or with avidin, which captures M13 at the biotin-functionalized tail, and compare orientational modes of reporter capture for the side- versus tip-binding recognition interactions. The number of captured M13 is greater for side-binding than for tip-binding, as expected from the number of recognition groups. Whereas two-thirds of side-bound M13 captured by an anti-M13 antibody bind immediately after colliding with the membrane, tip-bound M13 prominently exhibit three additional orientational modes that require M13 to reorient to enable binding. These results are consistent with the idea that the elongated M13 shape couples with the complex flow field in an open and disordered fibrous LFA membrane to enhance capture.

AB - Raman spectroscopy has previously been used to identify eukaryotic and prokaryotic cells. While prokaryotic cells are small in size and can be assessed by a single Raman spectrum, the larger size of eukaryotic cells and their complex organization requires the acquisition of multiple Raman spectra to properly characterize them. A Raman spectrum from a diffraction-limited spot at an arbitrary location within a cell results in spectral variations that affect classification approaches. To probe whole cells with Raman imaging at high spatial resolution is time consuming, because a large number of Raman spectra need to be collected, resulting in low cell throughput and impairing statistical analysis due to low cell numbers. Here we propose a method to overcome the effects of cellular heterogeneity by acquiring integrated Raman spectra covering a large portion of a cell. The acquired spectrum represents the mean macromolecular composition of a cell with an exposure time that is comparable to acquisition of a single Raman spectrum. Data sets were collected from T lymphocyte Jurkat cells, and pancreatic cell lines Capan1 and MiaPaca2. Cell classification by support vector machines was compared for single spectra, spectra of images and integrated Raman spectra of cells. The integrated approach provides better and more stable prediction for individual cells, and in the current implementation, the mean macromolecular information of a cell can be acquired faster than with the acquisition of individual spectra from a comparable region. It is expected that this approach will have a major impact on the implementation of Raman based cell classification. PMID- 27704072 TI - Recent advances in the chemical imaging of human fingermarks (a review). AB - This review highlights the considerable advances in the chemical imaging of human fingermarks that provide more chemical information, including numerous endogenous and exogenous constituents. Despite remarkable development in DNA analysis and recognition, human fingermark analysis remains one of the priority approaches available for obtaining reliable forensic evidence. Additional information about the donor can be obtained from the chemical composition of latent fingermarks in addition to the ridge pattern, such as the age, gender, medical history, and possible drug habits. The analytical approaches reviewed here include spectroscopy, mass spectrometry, immuno-labelling and electrochemical methods. Each method has different capabilities with respect to sensitivity, reproducibility, selectivity, reliability and ultimately applicability, either for use in routine forensic practice or in academic research work. The advantages of spectroscopic techniques, including infrared, Raman and micro-X-ray fluorescence spectroscopy, are the capabilities of a rapid and non-destructive imaging of fingermarks by providing spectral information on chemical composition. In addition, mass spectrometry imaging can provide spatially specific information on fingermark chemical composition. Recently, the use of immuno-labelling in latent fingermark detection has attracted significant attention because it can overcome the sensitivity and selectivity problems experienced with other existing methods. The electrochemical method has also been employed to image latent fingermarks by measuring the electric current changes with the spatial chemical composition from the ridges and valleys at high resolution to provide a third level of detail, which is especially useful for multicoloured background surfaces or for surfaces contaminated with blood or other bodily fluids. PMID- 27704073 TI - Development of a protease-resistant reporter to quantify BCR-ABL activity in intact cells. AB - A peptidase-resistant ABL kinase substrate was developed by identifying protease susceptible bonds on an ABL substrate peptide and replacing flanking amino acids with non-native amino acids. After an iterative design process, the lead, or designed, peptide X-A possesses a six-fold longer life in a cytosolic lysate than that of the starting peptide. The catalytic efficiency (kcat/KM) of purified ABL kinase for the lead peptide (125 s-1 MUM-1) is similar to that of the starting peptide (103 s-1 MUM-1) demonstrating preservation of the peptide's ability to serve as a kinase substrate. When incubated in cytosolic lysates, the lead peptide is slowly degraded into 4 fragments over time. In contrast, when loaded into intact cells, the peptide is metabolized into 5 fragments, with only 2 of the fragments corresponding to those in the lysate. Thus the two environments possess differing peptidase activities, which must be accounted for when designing peptidase-resistant peptides. In both settings, the substrate is phosphorylated by BCR-ABL providing a readout of BCR-ABL activity. A small panel of tyrosine kinase inhibitors verified the substrate's specificity for BCR ABL/ABL kinase activity in both lysates and cells in spite of the multitude of other kinases present. The designed peptide X-A acts as a long-lived BCR-ABL kinase reporter in the leukemic cells possessing the BCR-ABL mutation. PMID- 27704074 TI - Signal amplification of microRNAs with modified strand displacement-based cycling probe technology. AB - Micro ribose nucleic acids (miRNAs) play an important role in biological processes such as cell differentiation, proliferation and apoptosis. Therefore, miRNAs are potentially a powerful marker for monitoring cancer and diagnosis. Here, we present sensitive signal amplification for miRNAs based on modified cycling probe technology with strand displacement amplification. miRNA was captured by the template coupled with beads, and then the first cycle based on SDA was repeatedly extended to the nicking end, which was produced by the extension reaction of miRNA. The products generated by SDA are captured by a molecular beacon (MB), which is designed to initiate the second amplification cycle, with a similar principle to the cycling probe technology (CPT), which is based on repeated digestion of the DNA-RNA hybrid by the RNase H. After one sample enrichment and two steps of signal amplification, 0.1 pM of let-7a can be detected. The miRNA assay exhibits a great dynamic range of over 100 orders of magnitude and high specificity to clearly discriminate a single base difference in miRNA sequences. This isothermal amplification does not require any special temperature control instrument. The assay is also about signal amplification rather than template amplification, therefore minimising contamination issues. In addition, there is no need for the reverse transcription (RT) process. Thus the amplification is suitable for miRNA detection. PMID- 27704075 TI - A DNA array based on clickable lesion-containing hairpin probes for multiplexed detection of base excision repair activities. AB - DNA is under continuous assault by environmental and endogenous reactive oxygen and alkylating species, inducing the formation of mutagenic, toxic and genome destabilizing nucleobase lesions. Due to the implications of such genetic alterations in cell death, aging, inflammation, neurodegenerative diseases and cancer, many efforts have been devoted to developing assays that aim at analyzing DNA repair activities from purified enzymes or cell extracts. The present work deals with the conception and application of a new, miniaturized and parallelized on surface-DNA biosensor to measure base excision repair (BER) activities. Such a bio-analytical tool was built by using the "click chemistry" approach to immobilize, on a glass slide, fluorescent stem-loop DNA probes, which contain a specific nucleobase lesion. The performance of this new high-throughput DNA repair analysis technology was determined by detecting uracil N-glycosylase and AP-endonuclease activities from purified enzymes or in cell extracts. The applications of this device were extended to analyze, in cell extracts, the ability of two inhibitors (Uracil glycosylase inhibitor (Ugi) and methoxyamine (MX)) to block the excision of uracil and the cleavage of AP sites, respectively. Altogether, our results show that this new fluorescent DNA microarray platform provides an easy, rapid and robust method for detecting DNA N-glycosylase and AP endonuclease activities and evaluating the effects of BER inhibitors in a multiplexed fashion. PMID- 27704076 TI - A rapid SERS method for label-free bacteria detection using polyethylenimine modified Au-coated magnetic microspheres and Au@Ag nanoparticles. AB - A rapid, sensitive, and label-free SERS detection method for bacteria pathogens is reported for the first time. The method, which is based on the combination of polyethylenimine (PEI)-modified Au-coated magnetic microspheres (Fe3O4@Au@PEI) and concentrated Au@Ag nanoparticles (NPs), was named the capture-enrichment enhancement (CEE) three-step method. A novel Fe3O4@Au microsphere with monodispersity and strong magnetic responsiveness was synthesized as a magnetic SERS substrate and amino functionalized by PEI self-assembly. The negatively charged bacteria were quickly captured and enriched by the positively charged Fe3O4@Au@PEI microspheres, and the bacteria SERS signal was synergistically enhanced by using Fe3O4@Au@PEI microspheres and Au@Ag NPs in conjunction. The CEE three-step method proved useful in tap water and milk samples, and the total assay time required was only 10 min. Results further demonstrated that the CEE three-step method could be a common approach for detecting a wide range of bacteria, as verified by its detection of the Gram-positive bacterium E. coli and Gram-positive bacterium S. aureus at a detection limit of as low as 103 cells per mL. Therefore, our CEE three-step method offered the significant advantages of short assay time, simple operating procedure, and higher sensitivity than previously reported methods of SERS-based bacteria detection. PMID- 27704077 TI - Comparing surface properties of melanoma cells using time of flight secondary ions mass spectrometry. AB - Various techniques have been already reported to differentiate between normal (non-malignant) and cancerous cells based on their physico-chemical properties. This is relatively simple when studied cancerous cells originate from distant stages of cancer progression. Here, studies on chemical properties of two closely related human melanoma cell lines are presented: WM115 melanoma cells were taken from the vertical growth phase while WM266-4 from the skin metastatic site of the same patient. Their chemical properties were studied by two techniques, namely time-of-flight secondary ion mass spectra (ToF SIMS) and photothermal microspectroscopy (PTMS), used to record mass and photothermal spectra of cells, respectively. In our approach, independently of the spectra type, its full range, i.e. masses and wavenumbers within the range 0-500 kDa and 500-4000 cm-1, underwent a similar methodology for principal component analysis (PCA). PCA outcome shows results groupped depending on the sample type (either WM115 or WM266-4 cells). The results are independent of the method applied to study chemical properties of melanoma cells, indicating that cancer-related changes are large enough to be identified with these techniques and to differentiate between cells originating from vertical growth phase and skin metastatis. PMID- 27704078 TI - Closed bipolar electrode-enabled dual-cell electrochromic detectors for chemical sensing. AB - Bipolar electrodes (BPE) are electrically floating metallic elements placed in electrified fluids that enable the coupling of anodic and cathodic redox reactions at the opposite ends by electron transfer through the electrode. One particularly compelling application allows electron transfer reactions at one end of a closed BPE to be read out optically by inducing a redox-initiated change in the optical response function of a reporter system at the other end. Here, a BPE enabled method for electrochemical sensing based on the electrochromic response of a methyl viologen (MV) reporter is developed, characterized, and rendered in a field-deployable format. BPE-enabled devices based on two thin-layer-cells of ITO and Pt were fabricated to couple an analytical reaction in one cell with an MV reporter reaction, producing a color change in the complementary cell. Using Fe(CN)63/4- as a model analyte, the electrochemically induced color change of MV was determined initially by measuring its absorbance via a CCD camera coupled to a microscope. Then, smartphone-based detection and RGB analysis were employed to further simplify the sensing scheme. Both methods produced a linear relationship between the analyte concentration, the quantity of MV generated, and the colorimetric response, yielding a limit of detection of 1.0 MUM. Similar responses were observed in the detection of dopamine and acetaminophen. Further evolution of the device replaced the potentiostat with batteries to control potential, demonstrating the simplicity and portability of the device. Finally, the physical separation of the reporter and analytical cells renders the device competent to detect analytes in different (e.g. non-aqueous) phases, as demonstrated by using the electrochromic behavior of aqueous MV to detect ferrocene in acetonitrile in the analytical cell. PMID- 27704079 TI - Evaluation of a nitrogen-incorporated tetrahedral amorphous carbon thin film for the detection of tryptophan and tyrosine using flow injection analysis with amperometric detection. AB - We report on the analytical performance of a tetrahedral amorphous carbon (ta C:N) thin-film electrode in flow injection analysis with amperometric detection. Two model redox analytes were used to evaluate the electrode response because of their positive detection potentials and propensity (i.e., reaction products) to adsorb and foul sp2 carbon electrodes: tyrosine and tryptophan. ta-C:N electrodes are attractive for electroanalytical applications because they possesses many of the excellent properties of boron-doped nanocrystalline diamond (BDD) and they can be deposited at or near room temperature. The results show that the ta-C:N electrode exhibits lower background current and noise than glassy carbon (GC). The electrode was stable microstructurally at the positive potentials used for detection, ~1.1 V, of these two amino acids and it exhibited superior analytical detection figures of merit as compared to GC and as good or superior to BDD. The linear dynamic range for both analytes at ta-C:N was from 0.1 to 100 MUmol L-1, the sensitivity was 8-12 mA L mol-1, the short-term response variability was 1 2%, and the minimum detectable concentration was 89.7 +/- 0.9 nM (18.3 MUg L-1 or 0.46 ng) for tryptophan and 120 +/- 11 nM (21.7 MUg L-1 or 0.54 ng) for tyrosine. The analytical detection figures of merit for these amino acids at GC and BDD are also presented for comparison as is characterization data for the chemical composition and microstructure of the ta-C:N film. PMID- 27704080 TI - A compact imaging spectroscopic system for biomolecular detections on plasmonic chips. AB - In this study, we demonstrate a compact imaging spectroscopic system for high throughput detection of biomolecular interactions on plasmonic chips, based on a curved grating as the key element of light diffraction and light focusing. Both the curved grating and the plasmonic chips are fabricated on flexible plastic substrates using a gas-assisted thermal-embossing method. A fiber-coupled broadband light source and a camera are included in the system. Spectral resolution within 1 nm is achieved in sensing environmental index solutions and protein bindings. The detected sensitivities of the plasmonic chip are comparable with a commercial spectrometer. An extra one-dimensional scanning stage enables high-throughput detection of protein binding on a designed plasmonic chip consisting of several nanoslit arrays with different periods. The detected resonance wavelengths match well with the grating equation under an air environment. Wavelength shifts between 1 and 9 nm are detected for antigens of various concentrations binding with antibodies. A simple, mass-productive and cost-effective method has been demonstrated on the imaging spectroscopic system for real-time, label-free, highly sensitive and high-throughput screening of biomolecular interactions. PMID- 27704081 TI - Selective recognition and imaging of bacterial model membranes over mammalian ones by using cationic conjugated polyelectrolytes. AB - The development of new tools for the detection and fluorescence imaging of bacteria is of great interest in clinical diagnosis and food and environmental safety. In this work, we have explored the ability of two cationic fluorene-based conjugated polyelectrolytes, HTMA-PFP and HTMA-PFNT, emitting in the blue and red spectral regions respectively, to selectively label bacterial over mammalian cells. With this end in view, vesicles with lipid compositions mimicking those of bacterial or mammalian membranes were used as model membranes to explore the interaction of the polyelectrolytes with both systems in samples containing either a single type of vesicle or a mixture of both. Changes in the intrinsic fluorescence of HTMA-PFP and HTMA-PFNT were used to quantify the affinity of these polyelectrolytes for the model lipid membranes, while quenching experiments were employed to evaluate their selectivity to each lipid system. In addition, fluorescence microscopy experiments were performed to check the ability of polyelectrolytes to label the vesicles without affecting their integrity. Results showed that both polyelectrolytes rapidly label the model vesicles but they preferentially bind to those mimicking bacterial membranes, HTMA-PFNT being much more selective to this type of membranes than HTMA-PFP. Preliminary experiments with living bacteria and mammalian cells support this conclusion, showing that in samples with both types of cells together, HTMA-PFNT only images the bacterial cells, thus evidencing its potential use for the selective recognition and imaging of bacterial presence. PMID- 27704082 TI - Evaluation of drug-mediated arrhythmic changes in spontaneous beating cardiomyocytes by AFM. AB - Arrhythmia caused by drug-induced cardiotoxicity is among the leading reasons for late-stage drug attrition and is therefore a core subject in safety testing of new compounds. Alternative methods such as surface and interface characterization approaches for assessing the drug-mediated cardiotoxicity should be promoted, in order to reduce, refine and replace the use of laboratory animals. Here, we investigate the possibility of using known human Ether-a-go-go-Related Gene (hERG) channel blockers to induce irregular beating patterns in the mouse and human induced pluripotent stem cell-derived (miPSC and hiPSC) cardiomyocyte (CM) model systems. An AFM-based approach was developed to precisely monitor the beating interval and rate of cardiomyocytes. Verification was implemented using three individual cardiovascular compounds to validate the potential application of this AFM approach as a complementary drug screening tool. Consistent with previous reports, isoproterenol increased the beating rate, with a more pronounced effect in the mouse CMs, nifedipine increased the beating rate in a dose-dependent manner, and sotalol induced arrhythmias with a significant variation in beating interval responses at increasing concentrations. The results of this initial study show that accurate analysis of individual drug-mediated effects can be achieved using our method, comparable to previous reports, and that a well-controlled AFM test of ion channel manipulation on human and murine derived cardiomyocytes can be performed for investigation on multi-compound effects. Preliminary results indicate that the hERG blocker E-4031 can stimulate irregular, arrhythmic beating patterns in the cardiomyocytes from both species, and that immediate subsequent treatment with the hERG enhancer nicorandil can rescue these back to regular beating patterns, similar to those observed when the cells were untreated. This approach has not been extensively reported, and the use of our AFM system provides a platform to further investigate compound-induced ion channel effects in cardiomyocytes for potential application in pre-screening drug development stages. PMID- 27704083 TI - Fiber enhanced Raman spectroscopic analysis as a novel method for diagnosis and monitoring of diseases related to hyperbilirubinemia and hyperbiliverdinemia. AB - Fiber enhanced resonance Raman spectroscopy (FERS) is introduced for chemically selective and ultrasensitive analysis of the biomolecules hematin, hemoglobin, biliverdin, and bilirubin. The abilities for analyzing whole intact, oxygenated erythrocytes are proven, demonstrating the potential for the diagnosis of red blood cell related diseases, such as different types of anemia and hemolytic disorders. The optical fiber enables an efficient light-guiding within a miniaturized sample volume of only a few micro-liters and provides a tremendously improved analytical sensitivity (LODs of 0.5 MUM for bilirubin and 0.13 MUM for biliverdin with proposed improvements down to the pico-molar range). FERS is a less invasive method than the standard ones and could be a new analytical method for monitoring neonatal jaundice, allowing a precise control of the unconjugated serum bilirubin levels, and therefore, providing a better prognosis for newborns. The potential for sensing very low concentrations of the bile pigments may also open up new opportunities for cancer research. The abilities of FERS as a diagnostic tool are explored for the elucidation of jaundice with different etiologies including the rare, not yet well understood diseases manifested in green jaundice. This is demonstrated by quantifying clinically relevant concentrations of bilirubin and biliverdin simultaneously in the micro-molar range: for the case of hyperbilirubinemia due to malignancy, infectious hepatitis, cirrhosis or stenosis of the common bile duct (1 MUM biliverdin together with 50 MUM bilirubin) and for hyperbiliverdinemia (25 MUM biliverdin and 75 MUM bilirubin). FERS has high potential as an ultrasensitive analytical technique for a wide range of biomolecules and in various life-science applications. PMID- 27704085 TI - Optical disc technology-enabled analytical devices: from hardware modification to digitized molecular detection. AB - Beyond their essential applications in portable data storage for the past 30 years, optical discs and corresponding recording/reading technologies have been extensively explored with the ultimate goal of creating novel analytical tools for on-site chemical analysis and point-of-care (POC) medical diagnosis. In particular, the disc media (CD, DVD, and BD) are proven to be inexpensive and versatile substrate materials for the preparation of various biochips and microfluidic systems; conventional computer drives and disc players are widely adapted for biochip signal reading and microscopic imaging. Herein we provide an overview of such optical disc technology-enabled analytical devices, e.g., integrated systems developed from specifically fabricated analog disks, modified optical drives, or adapted software algorithms. PMID- 27704084 TI - Forster resonance energy transfer to impart signal-on and -off capabilities in a single microRNA biosensor. AB - Many studies have found that over- or under-expression of biomolecules called microRNAs (miRNA) regulates several diseases. Biosensors are in need to visually identify the relative expression level of miRNA to determine the direction these miRNA change in cells and tissues. Our established reporter+probe miRNA biosensor design requires that miRNA outcompete and displace the reporter from the probe. Once displaced, the reporter folds into a hairpin structure to force together a pair of Forster Resonance Energy Transfer (FRET) dyes. The donor and acceptor signal changes can be used to indicate the over-/under-expression of miRNA. The bright signal from the donor will indicate miRNA under-expression; the bright acceptor signal will indicate miRNA over-expression. Since close proximity of the dyes to each other and nucleic acids often quench fluorescence, polyethylene glycol spacers were added in-between the dyes and nucleic acids. We compared reporter designs with and without spacers to investigate the effects on the following analytical metrics: (1) extent of signal change, (2) limits of detection and quantitation, and (3) sensitivity. Systematic errors and amount of reporter+probe biosensor formed were evaluated for one of the biosensors. Cy3|Cy5 and 6-carboxyfluorescein (6-FAM)|ATTO 633 dye pairs on reporters containing spacers showed an increase in the acceptor signal change by ~190 and ~484%, respectively, compared to no spacers. Transduction mechanisms that enhance and quench the signal both showed LODs that ranged from 3-17 nanomolar (nM) with 100 nM of the biosensor. PMID- 27704086 TI - Comparison of the specificity and affinity of surface immobilised Affimer binders using the quartz crystal microbalance. AB - To enable multiplexed protein analysis through the use of microarrays, reliable molecules capable of specifically binding to a protein of interest with high affinity are required. Further, this specificity and affinity must be retained upon immobilization to the microarray surface. This study investigates the performance of surface bound Affimer proteins, comparing the affinity and specificity of different binders for closely related immunoglobulin molecules using the quartz crystal microbalance with dissipation monitoring (QCM-D). It is demonstrated that the surface bound Affimer proteins are highly specific, differentiating between their target IgG and other closely related IgG subclasses. The binding affinities of the protein aptamers for their target IgG molecules are determined to be in the nanomolar range, comparable to typical antibody-antigen binding affinities. While measurements herein are done using QCM D, the high specificity and binding affinities of the surface bound Affimer proteins opens applications in a range of microarray biosensors.

PMID- 27704088 TI - Fourier transform infrared spectroscopy on external perturbations inducing secondary structure changes of hemoglobin. AB - The secondary structure of proteins and their conformation are intimately related to their biological functions. In this study, heat-induced changes in the secondary structure and conformation of hemoglobin were investigated via infrared attenuated total reflection (IR-ATR) spectroscopy. The secondary structure changes of hemoglobin were derived from IR-ATR spectra using second derivatives and curve fitting. Thereby, the thermal denaturation temperature ranges and the secondary structure changes with temperature were revealed. More detailed information on the secondary structure and conformation was elucidated via two dimensional infrared correlation spectroscopy. This study deciphers the detailed conformational behavior of hemoglobin molecular changes along with temperature, and creates a general methodological framework for analyzing the heat-induced behavior of biomacromolecules. PMID- 27704089 TI - Microchip in situ electrosynthesis of silver metallic oxide clusters for ultra FAST detection of galactose in galactosemic newborns' urine samples. AB - This work describes for the first time the coupling of microfluidic chips (MC) to electrosynthetized silver metallic oxide clusters (AgMOCs). As an early demonstration of this novel approach, the ultrafast detection of galactose in galactosemic newborns' urine samples is proposed. AgMOCs were in situ electrosynthetized on integrated microchip platinum electrodes using a double pulse technique and characterized in full using scanning electronic microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS) and electrochemical techniques revealing the presence of silver oxides and electrocatalysis towards galactose as a galactosemia biomarker. Galactose detection in galactosemic newborns' urine samples proceeded in less than 30 s, differentiating between ill and healthy urine samples and requiring negligible urine sample consumption. The significance of the newborns' urine samples confirmed the analytical potency of the MC-AgMOCs approach for future implementation of screening for rare disease diagnosis such as galactosemia. PMID- 27704090 TI - Synthesis and characterization of DNA-quantum dot conjugates for the fluorescence ratiometric detection of unlabelled DNA. AB - A quantum dot-based ratiometrically responsive fluorescent sensor for unlabeled single-stranded DNA (ssDNA) is reported. Several technical issues concerning the development of high yield ssDNA-QD conjugation chemistry were addressed. The DNA sensor was synthesized by conjugating methacrylic phosphoramidite-functional oligonucleotides to water-soluble cadmium zinc sulfide core/zinc sulfide shell quantum dots (CdZnS/ZnS QDs). Duplex DNA was formed when the QD-bound ssDNA was incubated with its complement. Next, titration with PicoGreen resulted in FRET energy transfer from the dot to the dsDNA intercalating dye. The resulting ratio of the dye to QD integrated emissions is a calibratable metric for label-free DNA detection with a LOD of 3.8 nmol. PMID- 27704091 TI - Online coupling techniques in ambient mass spectrometry. AB - Since ambient mass spectrometry (AMS) has been proven to have low matrix effects and high salt tolerance, great efforts have been made for online coupling of several analytical techniques with AMS. These analytical techniques include gas chromatography (GC), liquid chromatography (LC), capillary electrophoresis (CE), surface plasmon resonance (SPR), and electrochemistry flow cells. Various ambient ionization sources, represented by desorption electrospray ionization (DESI) and direct analysis in real time (DART), have been utilized as interfaces for the online coupling techniques. Herein, we summarized the advances in these online coupling methods. Close attention has been paid to different interface setups for coupling, as well as limits of detection, tolerance to different matrices, and applications of these new coupling techniques. PMID- 27704092 TI - Towards DNA methylation detection using biosensors. AB - DNA methylation, a stable and heritable covalent modification which mostly occurs in the context of a CpG dinucleotide, has great potential as a biomarker to detect disease, provide prognoses and predict therapeutic responses. It can be detected in a quantitative manner by many different approaches both genome-wide and at specific gene loci, in various biological fluids such as urine, plasma, and serum, which can be obtained without invasive procedures. The current, classical methods are effective in studying DNA methylation patterns, however, for the most part; they have major drawbacks such as expensive instruments, complicated and time consuming protocols as well as relatively low sensitivity, and high false positive rates. To overcome these obstacles, great efforts have been made toward the development of reliable sensor devices to solve these limitations, providing sensitive, fast and cost-effective measurements. The use of biosensors for DNA methylation biomarkers has increased in recent years, because they are portable, simple, rapid, and inexpensive which offers a straightforward way to detect methylated biomarkers. In this review, we give an overview of the conventional techniques for the detection of DNA methylation and then will focus on recent advances in biosensor based methylation detection that eliminate bisulfite conversion and PCR amplification. PMID- 27704093 TI - Smart sensory materials for divalent cations: a dithizone immobilized membrane for optical analysis. AB - An optode for Cu(ii), Cd(ii), Zn(ii) and Hg(ii) sensing has been designed by immobilization of dithizone on a triacetylcellulose membrane (mem-DTZ). The sorption of the metal ions on the mem-DTZ has been thoroughly characterized, in particular sorption kinetics, sorption isotherms and profiles as a function of the pH have been studied. Methods to assess the concentrations of the cations, both individually and in a mixture, in unknown samples, have been developed. In particular, UV-vis spectra and digital information of pictures taken by using a common desktop scanner, of the mem-DTZ sensor after equilibration with different solutions, were acquired and they were correlated with the concentration of the metal ions in solutions. For the single analyte determination, the RGB parameters of the pictures were subjected to Principal Component Analysis (PCA); otherwise the UV-vis spectra of a mixture of two cations were elaborated by Partial Least Squares (PLS) Regression. The membrane responds to the divalent cations by changing colour reversibly. The response time of the mem-DTZ is about 1 h for Cd(ii), Hg(ii) and Zn(ii), but longer for Cu(ii): more than 10 h are required. The linear interval is in the range of about 10-7 to 10-5 M for all metal ions. The limit of detection (LOD) is around 10-6 M for Cu(ii), Cd(ii) and Hg(ii); for Zn(ii) a lower LOD of 10-7 M is obtained. The applicability of mem-DTZ to real samples has been proved by analysis of the four metal cations in a certificate material (Sewage Sludge CC136A), white wine, and drinking water samples.

A Qualitative Contextual Evaluation and Visioning Effort. AB - OBJECTIVES: Electronic health information overload makes it difficult for providers to quickly find and interpret information to support care decisions. The purpose of this study was to better understand how clinicians use information in critical care to support the design of improved presentation of electronic health information. METHODS: We conducted a contextual analysis and visioning project. We used an eye-tracker to record 20 clinicians' information use activities in critical care settings. We played video recordings back to clinicians in retrospective cued interviews and queried: 1) context and goals of information use, 2) impacts of current display design on use, and 3) processes related to information use. We analyzed interview transcripts using grounded theory-based content analysis techniques and identified emerging themes. From these, we conducted a visioning activity with a team of subject matter experts and identified key areas for focus of design and research for future display designs. RESULTS: Analyses revealed four unique critical care information use activities including new patient assessment, known patient status review, specific directed information seeking, and review and prioritization of multiple patients. Emerging themes were primarily related to a need for better representation of dynamic data such as vital signs and laboratory results, usability issues associated with reducing cognitive load and supporting efficient interaction, and processes for managing information. Visions for the future included designs that: 1) provide rapid access to new information, 2) organize by systems or problems as well as by current versus historical patient data, and 3) apply intelligence toward detecting and representing change and urgency. CONCLUSIONS: The results from this study can be used to guide the design of future acute care electronic health information display. Additional research and collaboration is needed to refine and implement intelligent graphical user interfaces to improve clinical information organization and prioritization to support care decisions. PMID- 27704140 TI - RhoA/ROCK signaling regulates TGFbeta-induced epithelial-mesenchymal transition of lens epithelial cells through MRTF-A. AB - Transforming growth factor (TGF)-beta-induced epithelial-mesenchymal transition (EMT) leads to the formation of ocular fibrotic pathologies, such as anterior subcapsular cataract and posterior capsule opacification. Remodeling of the actin cytoskeleton, mediated by the Rho family of GTPases, plays a key role in EMT, however, how actin dynamics affect downstream markers of EMT has not been fully determined. Our previous work suggests that myocardin related transcription factor A (MRTF-A), an actin-binding protein, might be an important mediator of TGFbeta-induced EMT in lens epithelial cells. The aim of the current study was to determine the requirement of RhoA/ROCK signaling in mediating TGFbeta-induced nuclear accumulation of MRTF-A, and ultimate expression of alpha-smooth muscle actin (alphaSMA), a marker of a contractile, myofibroblast phenotype. Using rat lens epithelial explants, we demonstrate that ROCK inhibition using Y-27632 prevents TGFbeta-induced nuclear accumulation of MRTF-A, E-cadherin/beta-catenin complex disassembly, and alphaSMA expression. Using a novel inhibitor specifically targeting MRTF-A signaling, CCG-203971, we further demonstrate the requirement of MRTF-A nuclear localization and activity in the induction of alphaSMA expression. Overall, our findings suggest that TGFbeta-induced cytoskeletal reorganization through RhoA/ROCK/MRTF-A signaling is critical to EMT of lens epithelial cells. PMID- 27704142 TI - HIV-1 infection, microenvironment and endothelial cell dysfunction. AB - HIV-1 promotes a generalized immune activation that involves the main targets of HIV-1 infection but also cells that are not sensitive to viral infection. ECs display major dysfunctions in HIV+ patients during long-standing viral infection that persist even in the current cART era, in which new-generation drugs have reduced dysmetabolic side effects and successfully impeded viral replication. In vivo studies have failed to demonstrate the presence of replicating virus in ECs suggesting that a direct role of the virus is unlikely, and implying that the mechanism accounting for vascular dysfunction may rely on the indirect action of molecules released in the microenvironment by HIV-1-infected cells. This article reviews the current understanding of how HIV-1 infection can contribute to vascular dysfunction. In particular, we discuss the emerging role played by different HIV-1 proteins in driving inflammation and EC dysregulation, and highlight the need to target them for therapeutic benefit. PMID- 27704141 TI - Toward laboratory blood test-comparable photometric assessments for anemia in veterinary hematology. AB - Anemia associated with intestinal parasites and malnutrition is the leading cause of morbidity and mortality in small ruminants worldwide. Qualitative scoring of conjunctival redness has been developed so that farmers can gauge anemia in sheep and goats to identify animals that require treatment. For clinically relevant anemia diagnosis, complete blood count-comparable quantitative methods often rely on complicated and expensive optical instruments, requiring detailed spectral information of hemoglobin. We report experimental and numerical results for simple, yet reliable, noninvasive hemoglobin detection that can be correlated with laboratory-based blood hemoglobin testing for anemia diagnosis. In our pilot animal study using calves, we exploit the third eyelid (i.e., palpebral conjunctiva) as an effective sensing site. To further test spectrometer-free (or spectrometerless) hemoglobin assessments, we implement full spectral reconstruction from RGB data and partial least square regression. The unique combination of RGB-based spectral reconstruction and partial least square regression could potentially offer uncomplicated instrumentation and avoid the use of a spectrometer, which is vital for realizing a compact and inexpensive hematology device for quantitative anemia detection in the farm field. PMID- 27704139 TI - Pigmy MicroRNA: surveillance cops in Therapies kingdom. AB - MicroRNAs (miRNAs) are well preserved in every animal. These pigmy sized non coding RNAs (21-23 nt), scattered in genome, are responsible for micromanaging the versatile gene regulations. Involvement of miRNAs was surveillance cops in all human diseases including cardiovascular defects, tumor formation, reproductive pathways, and neurological and autoimmune disorders. The effective functional role of miRNA can be reduced by chemical entities of antisense oligonucleotides and versatile small molecules that support the views of novel therapy of different human diseases. In this study, we have updated our current understanding for designing and synthesizing miRNA-controlling therapeutic chemicals. We have also proposed various in-vivo delivery strategies and their ongoing challenges to combat the incorporation hurdles in live cells and animals. Lastly, we have demonstrated the current progress of miRNA modulation in the treatment of different human diseases that provides an alternative approach of gene therapy. PMID- 27704143 TI - 48 week outcomes of maraviroc-containing regimens following the genotypic or Trofile assay in HIV-1 failing subjects: the OSCAR Study. AB - This study assessed the 48-week efficacy of an antiretroviral therapy including maraviroc following the assessment of co-receptor tropism by use of Geno2Pheno algorithm or the Trofile phenotypic assay in failing treatment-experienced HIV-1 patients. This was a multicenter, randomized, open-label, non-inferiority trial. Treatment-experienced subjects with HIV-RNA >=500 copies/mL were randomized (1:1) to undergo co-receptor tropism testing by the Geno- 2Pheno algorithm (with a false positive rate >10%) or the Trofile assay before starting a new antiretroviral treatment which included maraviroc. The primary endpoint was the 48 week proportion of patients with treatment success (TS). Intention-to-treat analyses are also reported. One hundred and fifty-five experienced patients were analysed: 77 patients in the Trofile arm and 78 in the Genotype arm. The 48-week proportion of TS was 87% in the Trofile arm and 89% in the Genotype arm (difference: 1.5%, 95%CI: -8.9% to 11.8%) suggesting non-inferiority. In the Trofile arm, 10 patients had treatment failure: 5 viral rebound, 5 discontinuations. In the Genotype arm, 9 patients had treatment failure: 7 viral rebound, 2 lost to follow-up. CD4+ significantly increased from baseline to week 48 in both arms. 48-week treatment success was similar for maraviroc-including therapy prescribed following the Trofile phenotypic assay or Geno2Pheno algorithm. PMID- 27704144 TI - Bacterial agents as a cause of infertility in humans. AB - Infertility is a problem affecting almost 15% of couples. There are many causes for this condition, among which urogenital bacterial infections seem to play an important role. Many studies have explained the mechanisms by which bacteria cause infertility both in men and women. Therefore we undertook this study to evaluate the presence of genito-urinary infections in infertile couples who sought counselling to investigate their condition. Microbiological analysis was performed on semen and vaginal/cervical samples of both partners of each couple. The percentage of individuals affected by a urogenital bacterial infection was between 14 and 20%. More significantly, most of the species isolated both in men and women have been described in the literature as potential causes of infertility. PMID- 27704145 TI - Transcriptional activity of human endogenous retrovirus in Albanian children with autism spectrum disorders. AB - Recent studies suggest that autism spectrum disorders (ASD) result from interactions between genetic and environmental factors, whose possible links could be represented by epigenetic mechanisms. Here, we investigated the transcriptional activity of three human endogenous retrovirus (HERV) families, in peripheral blood mononuclear cells (PBMCs) from Albanian ASD children, by quantitative real-time PCR. We aimed to confirm the different expression profile already found in Italian ASD children, and to highlight any social and family health condition emerging from information gathered through a questionnaire, to be included among environmental risk factors. The presence of increased HERV-H transcriptional activity in all autistic patients could be understood as a constant epigenetic imprinting of the disease, potentially useful for early diagnosis and for the development of effective novel therapeutic strategies. PMID- 27704146 TI - First evidence of HERV-H transcriptional activity reduction after methylphenidate treatment in a young boy with ADHD. AB - Human endogenous retroviruses (HERVs) have been associated with many complex diseases including neuropsychiatric diseases, such as attention deficit hyperactivity disorder (ADHD). In ADHD an over-expression of HERV-H family in peripheral blood mononuclear cells has been documented. It has been hypothesized that HERVs may represent the link between genetic and environmental risk factors, contributing to the clinical onset and/or to the progression of the neurodevelopmental disease. The effect of pharmacological treatment on HERV transcriptional activity in psychiatric disorders has been attracting attention. Using a real-time RT-PCR we investigated the influence of methylphenidate on HERV transcription in peripheral blood mononuclear cells of a young patient with ADHD. In this clinical case we describe for the first time the reduction of HERV-H expression and the significant improvement of ADHD symptoms after 6 months of methylphenidate treatment. PMID- 27704147 TI - Impact of hepatobiliary phase liver MRI versus Contrast-Enhanced Ultrasound after an inconclusive extracellular gadolinium-based contrast-enhanced MRI for the diagnosis of benign hepatocellular tumors. AB - PURPOSE: To compare the added values of hepatobiliary phase (HBP) MRI and contrast-enhanced ultrasound (CEUS) in addition to inconclusive extracellular gadolinium-based contrast-enhanced MRI (CE-MRI) to characterize benign hepatocellular tumors (BHT). METHODS: Eighty-three BHT-46 focal nodular hyperplasia (FNH) and 37 hepatocellular adenomas (HCA)-with inconclusive CE-MRI in 54 patients (43 women and 11 men, mean age 42 years old +/- 14.8) were retrospectively analyzed. All patients underwent both HBP-MRI and CEUS. Two radiologists independently reviewed 2 sets of images, SET-1: CE-MRI and HBP-MRI; SET-2: CE-MRI and CEUS, and classified lesions as "definite FNH," "possible FNH," or "definitely not FNH." Sensitivity (Se) and specificity (Spe) were compared between the two sets; subgroup analyses according to the lesion's size were performed. RESULTS: Regardless of lesion size, the respective Se and Spe of both datasets were not statistically different (95.7 and 100% vs. 76.1 and 94.6% for set-1 and -2 respectively; p = 0.18). For lesions larger than 35 mm, although both sets had similar specificity (100%), sensitivity was higher for SET-1 (100% vs. 40%); p = 0.04. Tumor classifications using SET-1 and SET-2 could have changed patient management in 35/54 (64.8%) and 33/54 (61.1%) of all patients, respectively. CONCLUSIONS: HBP-MRI or CEUS should be performed after an inconclusive CE-MRI. Both can change patient management by avoiding unnecessary biopsy or surveillance. The use of HBP-MRI should be advocated over CEUS in larger (>35 mm) lesions. PMID- 27704148 TI - Fluoroscopy versus sonography for image guidance in peripheral MSK intervention.

PMID- 27704149 TI - Checkpoint inhibitors and radiation treatment in Hodgkin's lymphoma : New study concepts of the German Hodgkin Study Group. AB - BACKGROUND: Patients with classical Hodgkin's lymphoma (cHL) have a good prognosis even in advanced stages. However, combined chemo- and radiotherapy, as the standard of care, is also associated with treatment-related toxicities such as organ damage, secondary neoplasias, infertility, or fatigue and long-term fatigue. Many patients suffer from this burden although their cHL was cured. Therefore, the efficacy of immune checkpoint inhibitors like anti-PD1/PD-L1 antibodies in the treatment of solid cancers and also in HL offers new options. A remarkable and durable response rate with a favorable toxicity profile was observed in heavily pretreated cHL patients. METHODS: Planning to perform prospective randomized clinical trials in the content of radio-immune treatment in patients with Hodgkin's lymphoma (HL), we transferred the results of preliminary clinical studies and basic research in clinical relevant study concepts. RESULTS: Based on these promising early phase trial data, the German Hodgkin Study Group (GHSG) will investigate innovative treatment regimens in upcoming phase II trials. CONCLUSION: The therapeutic efficacy and potential synergies of anti-PD1 antibodies in combination with chemo- or radiotherapy will be investigated in various settings of HL.

PMID- 27704153 TI - In the footsteps of Bonney and Nichols: hysterectomy during surgical repair of pelvic organ prolapse. AB - Based on the available urogynecological literature, the role of hysterectomy in the surgical strategy of pelvic organ prolapse (POP) repair remains controversial. Currently, there are no data to favor either the removal or preservation of the uterus in women with POP. The findings that hysterectomy may contribute to a higher success rate and to the development of urinary incontinence and/or female sexual dysfunction are not supported by evidence. It is not clear why both hysteropexy was sometimes performed in the presence of overt uterine prolapse and/or concomitant vaginal hysterectomy was often included in vaginal prolapse repair in the absence of uterine prolapse. In our opinion, it makes both anatomical and clinical sense to remove the uterus only (and always) when the uterus is one of the pelvic organs directly involved in the prolapse, but to preserve and suspend the uterus otherwise. PMID- 27704154 TI - Age-related alterations in female obturator internus muscle. AB - INTRODUCTION AND HYPOTHESIS: Pelvic floor muscle rehabilitation is a widely utilized, but often challenging therapy for pelvic floor disorders, which are prevalent in older women. Regimens involving the use of appendicular muscles, such as the obturator internus (OI), have been developed for strengthening of the levator ani muscle (LAM). However, changes that lead to potential dysfunction of these alternative targets in older women are not well known. We hypothesized that aging negatively impacts OI architecture, the main determinant of muscle function, and intramuscular extracellular matrix (ECM), paralleling age-related alterations in LAM. METHODS: OI and LAM were procured from three groups of female cadaveric donors (five per group): younger (20 - 40 years), middle-aged (41 - 60 years), and older (>=60 years). Architectural predictors of the excursional (fiber length, L f), force-generating (physiological cross-sectional area, PCSA) and sarcomere length (L s) capacity of the muscles, and ECM collagen content (measure of fibrosis) were determined using validated methods. The data were analyzed using one-way ANOVA and Tukey's post-hoc test with a significance level of 0.05, and linear regression. RESULTS: The mean ages of the donors in the three groups were 31.2 +/- 2.3 years, 47.6 +/- 1.2 years, and 74.6 +/- 4.2 years (P < 0.005). The groups did not differ with respect to parity or body mass index (P > 0.5). OI L f and L s were not affected by aging. Age >60 years was associated with a substantial decrease in OI PCSA and increased collagen content (P < 0.05). Reductions in OI and LAM force-generating capacities with age were highly correlated (r 2 = 0.9). CONCLUSIONS: Our findings of age-related decreases in predicted OI force production and fibrosis suggest that these alterations should be taken into consideration, when designing pelvic floor fitness programs for older women. PMID- 27704155 TI - Visuo-oculomotor skills related to the visual demands of sporting environments. AB - The aim of this study was to assess the visuo-oculomotor skills of gaze orientation in selected sport activities relative to visual demands of the sporting environment. Both temporal and spatial demands of the sporting environment were investigated: The latency and accuracy of horizontal saccades and the gain of the horizontal smooth pursuit of the sporting environment were investigated in 16 fencers, 19 tennis players, 12 gymnasts, 9 swimmers and 18 sedentary participants. For the saccade test, two sequences were tested: In the fixed sequence, participants knew in advance the time interval between each target, as well as the direction and the amplitude of its reappearance; in the Freyss sequence however, the spatial changes of the target (direction and amplitude) were known in advance by participants but the time interval between each target was unknown. For the smooth-pursuit test, participants were instructed to smoothly track a target moving in a predictable sinusoidal, horizontal way without corrective ocular saccades, nor via anticipation or head movements. The results showed no significant differences between specificities of selected sporting activities via the saccade latency (although shorter than in non-athletes), contrary to saccade accuracy and the gain of smooth pursuit. Higher saccade accuracy was observed overall in fencers compared to non-athletes and all other sportsmen with the exception of tennis players. In the smooth pursuit task, only tennis players presented a significantly higher gain compared to non-athletes and gymnasts. These sport-specific characteristics of the visuo oculomotor skills are discussed with regard to the different cognitive skills such as attentional allocation and cue utilization ability as well as with regard to the difference in motor preparation. PMID- 27704156 TI - Oxidative stress and gene expression profiling of cell death pathways in alpha cypermethrin-treated SH-SY5Y cells. AB - In this study, we investigated the induction of oxidative stress and apoptosis in human neuroblastoma cell line SH-SY5Y in response to alpha-cypermethrin (alpha CYPER) exposure. MTT and LDH assays were carried out to assess the alpha-CYPER cytotoxicity. The IC50 value for alpha-CYPER was calculated to be 78.3 +/- 2.98 uM for the MTT assay and 71.5 +/- 3.94 uM for LDH assay. The pyrethroid alpha CYPER (1-100 uM), in a dose-dependent manner, induced a significant increase in lipid peroxides measured as malondialdehyde (MDA) and in the levels of nitric oxide (NO). The neuroprotective role of three antioxidants, melatonin (MEL), Trolox and N-acetylcysteine (NAC) against alpha-CYPER-induced oxidative stress was examined. Compared to other antioxidants, MEL (1 uM) treatment showed the most effective protection against alpha-CYPER-induced lipid peroxidation and NO production. The effects of alpha-CYPER on gene expression profiling of cell death pathway in human neuroblastoma SH-SY5Y cells were also investigated. Of the 84 genes examined (P < 0.001; fold change >1.5), changes in mRNA levels were detected in 39 genes: 36 were up-regulated and 3 were down-regulated. A greater fold change reversion than 3.5-fold was observed on the up-regulated ATP6V1G2, BCL2, CASP9, FAS, GADD45A, SPATA2, SYCP2, ATG7, NFKB1, SNCA, ULK1 and JPH3 genes. The results demonstrated that alpha-CYPER alters the expression of apoptosis-, autophagy- and necrosis genes as well as induces oxidative stress which may lead to DNA damage. The detailed knowledge of the changes in gene expression obtained will provide a basis for further elucidating the molecular mechanisms of the alpha-CYPER-induced toxicity. PMID- 27704157 TI - Different synovial vasculogenic profiles of primary, rapidly destructive and osteonecrosis-induced hip osteoarthritis. An immunohistochemistry study. AB - PURPOSE: To present a hypothesis regarding the pathways of angiogenesis in primary versus secondary hip osteoarthritis (OA). METHODS: In synovial tissue samples provided by 57 consecutive patients who underwent hip arthroplasty, immunohistochemical examinations were performed using the following angiogenesis related antibodies: VEGF-A, COX-2, maspin and the endothelial cells markers CD31 and CD105. The cases were divided into three categories: classic primary hip OA (group A; n = 16), rapidly destructive hip OA (group B; n = 24) and hip OA secondary to avascular osteonecrosis of the femoral head (group C; n = 17). The endothelial area (EA) was digitally quantified for both CD31 and CD105. RESULTS: The large mature vessels with CD105-positive activated endothelium predominated in group C, which also showed the highest CD105 median EA value (7.31 +/- 4.01, compared to 4.76 +/- 3.73 for group A and 6.69 +/- 3.53 for group B). In groups A and B, synovial cell hyperplasia and the predominance of small immature vessels were characteristic. CD105, VEGF-A and COX-2 were focally seen in the synovial membrane, without maspin positivity. CONCLUSIONS: The severity of hip OA can be related to angiogenesis pathways that are not maspin-mediated. In primary hip OA, angiogenesis may be induced by a combined mechanism: hypoxia-related VEGF dependent vasculogenesis and endothelial differentiation of the activated pluripotent cells, which are released from the hyperplastic synovial cells layer. An endothelial mesenchymal transition is assumed to be involved in the fibrotic process. PMID- 27704158 TI - Influence of pre-operative tear size and tendon retraction on repair outcomes for isolated subscapularis tears. AB - PURPOSE: The purpose of this study was to investigate the influence of tendon tear size, in terms of length and retraction, on clinical and anatomic outcomes following repair for isolated subscapularis tears. METHODS: The records of 47 consecutive repairs of isolated subscapularis lesions were studied to correlate pre-operative tear characteristics with clinical and radiographic outcomes. RESULTS: Forty patients had complete radiographic outcomes at 3.2 +/- 1.1 years, of which 36 had complete clinical outcomes at 3.5 +/- 0.9 years. Re-tears were observed in five shoulders (12.5 %). Fatty infiltration increased by one grade in 20 shoulders (50 %), and by two grades in four shoulders (10 %). Pre-operative tear size was associated with the post-operative belly-press test (BPT) (p = 0.042) and fatty infiltration (p = 0.051). Pre-operative tendon retraction was associated with post-operative BPT (p < 0.001) and fatty infiltration (p = 0.023). CONCLUSIONS: Our results do not entirely prove that prognostic factors used for superior and posterior tendon tears apply for the subscapularis. Pre operative tendon retraction is a better predictor of outcomes than tear size. When tear size and tendon retraction are simultaneously severe, re-tears and poor outcomes are more likely. PMID- 27704159 TI - Current state of the art in total knee arthroplasty computer navigation. AB - PURPOSE: Computer-assisted surgery in orthopaedics is passing through the initial adapter phase of technology adoption. It started more than 20 years ago, but the uptake of technology is still not widespread. The purpose of this article is to introduce the reader to the basic technology and familiarize with the terminology used in the computer navigation. METHODS: During this time, the technology has matured and we have the evidence to prove its benefits for patients. Not only does it help placing the prosthetic components in correct orientation, it also helps with other parameters like blood loss and fat embolism reduction. In addition to being a teaching and training tool, it has also opened new areas of research which now question the traditional practices. Since it is not in commonly used, the basic aspects of computer navigation are not very well known. RESULTS: This paper outlines some important definitions and restates the classification of navigation within the spectrum of computer-assisted technologies; it then elaborates on the key principles behind navigation in knee arthroplasty and goes through some of the differences between navigation systems. Finally, it describes in some detail the surgical steps with an image-free knee navigation system. CONCLUSIONS: Computer-assisted navigation is not mainstream yet, but this article should help readers unfamiliar with the technology to understand the basic terms and how it actually works. LEVEL OF EVIDENCE: III. PMID- 27704160 TI - Are stunted young Indonesian children more likely to be overweight, thin, or have high blood pressure in adolescence? AB - OBJECTIVES: To determine whether stunted young children are at greater risk of (1) overweight/obesity or thinness, and (2) high blood pressure (HBP) in adolescence. METHODS: A secondary data analysis using the Indonesian Family Life Survey waves 1 (1993) to 4 (2007). We generated a 14-year follow-up cohort (1993 2007) and two 7-year cohorts (1993-2000 and 2000-2007) of children aged 2.0-4.9 years. Stunting (HAZ < -2), thinness (BMIZ < -2), and overweight/obesity (BMIZ > +1) were determined based upon the WHO Child Growth Standards. HBP (>90th percentile) was interpreted using the 4th Report on the Diagnosis of HBP in Children and Adolescents. RESULTS: 765, 1083, and 1589 children were included in the 14-year cohort, and the two 7-year cohort analyses, respectively. In the 7 year cohorts, early life stunting was inversely associated with overweight/obesity (prevalence ratio 0.32 and 0.38, respectively; P < 0.05), but no significant association was found with the 14-year cohort. There was no significant association between childhood stunting and thinness at adolescence or in the odds/likelihood of having high systolic or diastolic blood pressure. CONCLUSIONS: We found no association between early life stunting and overweight/obesity, thinness and HBP in adolescence.

AB - Antiphospholipid syndrome (APS) is characterized by thromboses and/or pregnancy losses. Laboratory criterion for the diagnosis of APS is the presence of antiphospholipid antibodies (anticardiolipin, anti-beta2-glycoprotein I (abeta2gpI) and lupus anticoagulant). On the one hand, the latest classification criteria for the diagnosis of APS emphasized that thrombotic manifestations of the syndrome should be without any signs of an inflammatory process, while on the other hand, some recent reports have suggested that APS is a "pro-inflammatory state." This article is focused on the importance of TNF-alpha and annexin A2 (anxA2) for patients with vascular (thrombotic) manifestations of the primary APS. The classic antithrombotic and antiplatelet therapy does not protect APS patients from the development of recurrent thrombosis. Therefore, an urgent need for the introduction of new therapeutic approaches in the treatment of APS patients is obvious. This review provides a rationale for the necessity for the use of immunomodulatory medications that could interfere with beta2gpI binding to its receptor(s), such as anxA2, and/or inhibit TNF-alpha activity. PMID- 27704161 TI - Relationship between cigarette smoking and hyperuricemia in middle-aged and elderly population: a cross-sectional study. AB - The aim of the study was to estimate the cross-sectional association between cigarette smoking and the prevalence of hyperuricemia (HU) in the middle-aged and elderly males and females. A total of 3415 males and 2932 females were included in this study. HU was defined as SUA>= 416 mmol/L for males and >=360 mmol/L for females. The smoking status was classified into four categories based on daily smoking habit: (1) 0/day; (2) 1-10/day; (3) 11-20/day; and (4) >20/day. Multivariable logistic regressions were conducted to examine the aforementioned association. The prevalence of HU in the male and female sample was 25.0 and 10.0 %, respectively. In male subjects, the prevalence of HU in smokers (22.8 %) was significantly lower than that in non-smokers (26.5 %) (p = 0.016). Meanwhile, with adjustment for potential confounding factors, the prevalence of HU in smokers was still lower (OR = 0.83, 95 % CI 0.70-0.98, P = 0.033). Furthermore, a significantly inverse association between smoking status and HU was observed in the multivariable model. The multivariable-adjusted OR (95 % CI) for HU in the second, third and fourth category of smoking status was 0.84 (95 % CI 0.66-1.06), 0.90 (95 % CI 0.69-1.18) and 0.76 (95 % CI 0.58-0.99), respectively, compared with that in the first category. A clear trend (P for trend was 0.036) was observed. However, there was no significant association between cigarette smoking and HU in female subjects (P for trend was 0.739). This study indicated an inverse association between cigarette smoking and the prevalence of HU in the middle-aged and elderly male population, independent of some major confounding factors. The findings of this study expect further prospective studies to confirm the causal relationship. PMID- 27704163 TI - Incidental ferumoxytol artifacts in clinical brain MR imaging. AB - INTRODUCTION: Ferumoxytol (Feraheme) is a parenteral therapy approved for treatment of iron deficiency anemia. The product insert for ferumoxytol states that it may affect the diagnostic ability of MRI for up to 3 months. However, the expected effects may not be commonly recognized among clinical neuroradiologists. Our purpose is to describe the artifacts we have seen at our institution during routine clinical practice. METHODS: We reviewed the patients at our institution that had brain MRI performed within 90 days of receiving intravenous ferumoxytol. The imaging was reviewed for specific findings, including diffusion-weighted imaging vascular susceptibility artifact, gradient-echo echo-planar T2*-weighted vascular susceptibility artifact, SWI/SWAN vascular susceptibility artifact, hypointense vascular signal on T2-weighted images, pre-gadolinium contrast vascular enhancement on magnetization-prepared rapid acquisition gradient echo (MPRAGE) imaging, and effects on post-gadolinium contrast T1 imaging. RESULTS: Multiple artifacts were observed in patients having a brain MRI within 3 days of receiving intravenous ferumoxytol. These included susceptibility artifact on DWI, GRE, and SWAN/SWI imaging, pre-gadolinium contrast increased vascular signal on MPRAGE imaging, and decreased expected enhancement on post-gadolinium contrast T1 weighted imaging. CONCLUSION: Ferumoxytol can create imaging artifacts which complicate clinical interpretation when brain MRI is performed within 3 days of administration. Recognition of the constellation of artifacts produced by ferumoxytol is important in order to obviate additional unnecessary examinations and mitigate errors in interpretation. PMID- 27704164 TI - Human multipotent adult progenitor cells enhance islet function and revascularisation when co-transplanted as a composite pellet in a mouse model of diabetes. AB - AIMS/HYPOTHESIS: Hypoxia in the initial days after islet transplantation leads to considerable loss of islet mass and contributes to disappointing outcomes in the clinical setting. The aim of the present study was to investigate whether co transplantation of human non-endothelial bone marrow-derived multipotent adult progenitor cells (MAPCs), which are non-immunogenic and can secrete angiogenic growth factors during the initial days after implantation, could improve islet engraftment and survival. METHODS: Islets (150) were co-transplanted, with or without human MAPCs (2.5 * 105) as separate or composite pellets, under the kidney capsule of syngeneic alloxan-induced diabetic C57BL/6 mice. Blood glucose levels were frequently monitored and IPGTTs were carried out. Grafts and serum were harvested at 2 and 5 weeks after transplantation to assess outcome. RESULTS: Human MAPCs produced high amounts of angiogenic growth factors, including vascular endothelial growth factor, in vitro and in vivo, as demonstrated by the induction of neo-angiogenesis in the chorioallantoic membrane assay. Islet-human MAPC co-transplantation as a composite pellet significantly improved the outcome of islet transplantation as measured by the initial glycaemic control, diabetes reversal rate, glucose tolerance and serum C-peptide concentration compared with the outcome following transplantation of islets alone. Histologically, a higher blood vessel area and density in addition to a higher vessel/islet ratio were detected in recipients of islet-human MAPC composites. CONCLUSIONS/INTERPRETATION: The present data suggest that co-transplantation of mouse pancreatic islets with human MAPCs, which secrete high amounts of angiogenic growth factors, enhance islet graft revascularisation and subsequently improve islet graft function. PMID- 27704165 TI - The TetO rat as a new translational model for type 2 diabetic retinopathy by inducible insulin receptor knockdown. AB - AIMS/HYPOTHESIS: Although the renin-angiotensin system plays an important role in the progression of diabetic retinopathy, its influence therein has not been systematically evaluated. Here we test the suitability of a new translational model of diabetic retinopathy, the TetO rat, for addressing the role of angiotensin-II receptor 1 (AT1) blockade in experimental diabetic retinopathy. METHODS: Diabetes was induced by tetracycline-inducible small hairpin RNA (shRNA) knockdown of the insulin receptor in rats, generating TetO rats. Systemic treatment consisted of an AT1 blocker (ARB) at the onset of diabetes, following which, 4-5 weeks later the retina was analysed in vivo and ex vivo. Retinal function was assessed by Ganzfeld electroretinography (ERG). RESULTS: Retinal vessels in TetO rats showed differences in vessel calibre, together with gliosis. The total number and the proportion of activated mononuclear phagocytes was increased. TetO rats presented with loss of retinal ganglion cells (RGC) and ERG indicated photoreceptor malfunction. Both the inner and outer blood-retina barriers were affected. The ARB treated group showed reduced gliosis and an overall amelioration of retinal function, alongside RGC recovery, whilst no statistically significant differences in vascular and inflammatory features were detected. CONCLUSIONS/INTERPRETATION: The TetO rat represents a promising translational model for the early neurovascular changes associated with type 2 diabetic retinopathy. ARB treatment had an effect on the neuronal component of the retina but not on the vasculature. PMID- 27704166 TI - GAD vaccine reduces insulin loss in recently diagnosed type 1 diabetes: findings from a Bayesian meta-analysis. AB - AIMS/HYPOTHESIS: GAD is a major target of the autoimmune response that occurs in type 1 diabetes mellitus. Randomised controlled clinical trials of a GAD + alum vaccine in human participants have so far given conflicting results. METHODS: In this study, we sought to see whether a clearer answer to the question of whether GAD65 has an effect on C-peptide could be reached by combining individual-level data from the randomised controlled trials using Bayesian meta-analysis to estimate the probability of a positive biological effect (a reduction in C peptide loss compared with placebo approximately 1 year after the GAD vaccine). RESULTS: We estimate that there is a 98% probability that 20 MUg GAD with alum administered twice yields a positive biological effect. The effect is probably a 15-20% reduction in the loss of C-peptide at approximately 1 year after treatment. This translates to an annual expected loss of between -0.250 and 0.235 pmol/ml in treated patients compared with an expected 2 h AUC loss of 0.294 pmol/ml at 1 year for untreated newly diagnosed patients. CONCLUSIONS/INTERPRETATION: The biological effect of this vaccination should be developed further in order to reach clinically desirable reductions in insulin loss in patients recently diagnosed with type 1 diabetes. PMID- 27704167 TI - Efficacy of single-hormone and dual-hormone artificial pancreas during continuous and interval exercise in adult patients with type 1 diabetes: randomised controlled crossover trial. AB - AIMS/HYPOTHESIS: The aim of this study was to assess whether the dual-hormone (insulin and glucagon) artificial pancreas reduces hypoglycaemia compared with the single-hormone (insulin alone) artificial pancreas during two types of exercise. METHODS: An open-label randomised crossover study comparing both systems in 17 adults with type 1 diabetes (age, 37.2 +/- 13.6 years; HbA1c, 8.0 +/- 1.0% [63.9 +/- 10.2 mmol/mol]) during two exercise types on an ergocycle and matched for energy expenditure: continuous (60% [Formula: see text] for 60 min) and interval (2 min alternating periods at 85% and 50% [Formula: see text] for 40 min, with two 10 min periods at 45% [Formula: see text] at the start and end of the session). Blocked randomisation (size of four) with a 1:1:1:1 allocation ratio was computer generated. The artificial pancreas was applied from 15:30 hours until 19:30 hours; exercise was started at 18:00 hours and announced 20 min earlier to the systems. The study was conducted at the Institut de recherches cliniques de Montreal. RESULTS: During single-hormone control compared with dual hormone control, exercise-induced hypoglycaemia (plasma glucose <3.3 mmol/l with symptoms or <3.0 mmol/l regardless of symptoms) was observed in four (23.5%) vs two (11.8%) interventions (p = 0.5) for continuous exercise and in six (40%) vs one (6.25%) intervention (p = 0.07) for interval exercise. For the pooled analysis (single vs dual hormone), the median (interquartile range) percentage time spent at glucose levels below 4.0 mmol/l was 11% (0.0-46.7%) vs 0% (0-0%; p = 0.0001) and at glucose levels between 4.0 and 10.0 mmol/l was 71.4% (53.2-100%) vs 100% (100-100%; p = 0.003). Higher doses of glucagon were needed during continuous (0.126 +/- 0.057 mg) than during interval exercise (0.093 +/- 0.068 mg) (p = 0.03), with no reported side-effects in all interventions. CONCLUSIONS/INTERPRETATION: The dual-hormone artificial pancreas outperformed the single-hormone artificial pancreas in regulating glucose levels during announced exercise in adults with type 1 diabetes.

PMID- 27704168 TI - Adverse drug events in patients with advanced chronic conditions who have a prognosis of limited life expectancy at hospital admission. AB - PURPOSE: Adverse drug events (ADEs) lead to adverse clinical outcomes such as hospitalization. There is little information about the characteristics of ADEs in patients with advanced chronic conditions and have a prognosis of limited life expectancy. This study aimed to evaluate (i) the prevalence of ADEs at the time of admission to hospital, (ii) the causality, severity, and preventability of the ADEs, and (iii) the clinical and pharmacological characteristics associated with the ADEs. METHODS: This is a prospective cross-sectional study (county of Osona, Catalonia, Spain). We included patients who required palliative care as identified by the NECPAL CCOMS-ICO tool who were hospitalized in an acute geriatric unit (AGU). A system of alerts (trigger tool) was used together with a multidisciplinary review for the detection of the ADEs. RESULTS: Over the course of 10 months, 235 patients were recruited. Seventy-six ADEs affecting 24.68 % of the sample were identified, and of these, 23 (30.26 % of the ADEs; 8.51 % of the sample) were directly related to hospitalization. The multivariate logistic regression analysis identified the following risk factors: presence of extreme polypharmacy (>=10 medications) (OR = 3.02; 95 % CI = 1.48-6.19), anticholinergic burden according to the Anticholinergic Drug Scale (ADS) (OR = 2.32; 95 % CI = 1.13-4.78), and treatment complexity according to the Medication Regimen Complexity Index (MRCI) scale (OR = 2.90; 95 % CI = 1.44-5.83). The vast majority (94.45 %) of the ADEs were considered to be preventable. There were no differences in the survival of the patients. CONCLUSIONS: ADEs are common, largely preventable, and implicated in the hospitalization of patients who require palliative care. PMID- 27704169 TI - Hepatic expression of transcription factors affecting developmental regulation of UGT1A1 in the Han Chinese population. AB - PURPOSE: Complete or partial inactivity of UGT1A1, the unique enzyme responsible for bilirubin glucuronidation, is commonly associated with hyperbilirubinemia. We investigated the dynamic expression of UGT1A1, and that of the transcription factors (TFs) involved in its developmental regulation, during human hepatic growth in Han Chinese individuals. METHODS: Eighty-eight prenatal, pediatric, and adult liver samples were obtained from Han Chinese individuals. Quantitative real time polymerase chain reaction was used to evaluate mRNA expression of UGT1A1 and TFs including PXR, CAR, HNF1A, HNF4A, PPARA, etc. UGT1A1 protein levels and metabolic activity were determined by western blotting and high-performance liquid chromatography. Direct sequencing was employed to genotype UGT1A1*6 (211G?A) and UGT1A1*28 (TA6?TA7) polymorphisms. RESULTS: UGT1A1 expression was minimal in prenatal samples, but significantly elevated during pediatric and adult stages. mRNA and protein levels and metabolic activity were prominently increased (120-, 20-, and 10-fold, respectively) in pediatric and adult livers compared to prenatal samples. Furthermore, expression did not differ appreciably between pediatric and adult periods. Dynamic expression of TFs, including PXR, CAR, HNF1A, HNF4A, and PPARA, was consistent with UGT1A1 levels at each developmental stage. A pronounced correlation between expression of these TFs and that of UGT1A1 (P < 0.001) was observed. Moreover, UGT1A1*6 and UGT1A1*28 polymorphisms reduced levels of UGT1A1 by up to 40-60 %. CONCLUSIONS: Hepatic expression of transcription factors is associated with developmental regulation of UGT1A1 in the Han Chinese population. Moreover, UGT1A1 polymorphisms are associated with reduced expression of UGT1A1 mRNA and protein, as well as enzyme activity. PMID- 27704171 TI - Adaptive Capacity in Community Forest Management: A Systematic Review of Studies in East Asia. AB - This study investigated the indicators of adaptive capacity along with disturbances in community forest management systems in the East Asian countries, China, Japan and South Korea. Although these countries have centuries-old traditions of community-based forest management, they have been less researched in light of adaptive capacity for resilient social-ecological systems. Recent social and ecological disturbances bring about new challenges and/or opportunities to the capacity of forest related communities to adapt to rapidly changing conditions. Through a systematic review of the community forestry and related adaptive capacity literature in three East Asian countries, this study addressed the role of diverse knowledge systems, such as traditional and Western scientific knowledge, and civic traditions of self-organization in local communities that characterized adaptive capacity of this region. This study extends our understanding of community-based conservation efforts and traditions of this region, and adds to the understandings gleaned from studies of community forestry in the West and sacred forests in other parts of Asia and Africa. Further research on ways to increase adaptive capacity is needed in a site specific context. PMID- 27704170 TI - Memory and adaptive behavior in population dynamics: anti-predator behavior as a case study. AB - Memory allows organisms to forecast the future on the basis of experience, and thus, in some form, is important for the development of flexible adaptive behavior by animal communities. To model memory, we use the concept of hysteresis, which mathematically is described by the Preisach operator. As a case study, we consider anti-predator adaptation in the classic Lotka-Volterra predator-prey model. Despite its simplicity, the model allows us to naturally incorporate essential features of an adaptive system and memory. Our analysis and simulations show that a system with memory can have a continuum of equilibrium states with non-trivial stability properties. The main factor that determines the actual equilibrium state to which a trajectory converges is the maximal number achieved by the population of predator along this trajectory. PMID- 27704172 TI - Improvement of Postoperative Pain Control Processes and Outcomes in Veterans of a Surgical Intensive Care Unit. AB - BACKGROUND: Postoperative pain remains undertreated in critically ill patients. We hypothesized that the adequacy of pain control in our Surgical Intensive Care Unit (SICU) was above the reported average of 71 % in the literature and that the introduction of the critical care pain observation tool (CPOT) could improve it. We used a Lean Six Sigma methodology to improve our processes and quantify our improvement. PATIENTS AND METHODS: We retrospectively review 713 consecutive veterans admitted to our SICU. Between December 2014 and February 2015, postoperative pain was assessed every 2 h and rated "acceptable," "unacceptable," or "unable to assess". Between March 2015 and October 2015, postoperative pain was assessed with CPOT. Concurrently, we implemented a postoperative pain education program and documented this activity in the electronic medical record. RESULTS: The baseline adequacy of pain control was 78 %, which improved to 99 % after the introduction of CPOT. We concurrently achieved a 100 % median documentation of postoperative pain education in the electronic medical record. The introduction of CPOT improved the process sigma from 2.3 to 3.8. The process of documenting pain education achieved a process sigma of 3.1. CONCLUSIONS: The proportion of veterans with acceptable pain control in our SICU is higher than that reported in the literature and the application of a Six Sigma methodology that involved the introduction of the CPOT has allowed us to improve the perception of pain control and comply with the newest regulatory directives.

PMID- 27704175 TI - Cadmium(II)-based metal-organic nanotubes as solid-phase microextraction coating for ultratrace-level analysis of polychlorinated biphenyls in seawater samples. AB - In this study, stable cadmium(II)-based metal-organic nanotubes (Cd-MONTs) were prepared and used as a coating material for solid-phase microextraction (SPME) of polychlorinated biphenyls (PCBs) from environmental water samples. The as prepared Cd-MONT SPME coating material was characterized by thermal gravimetric analysis, scanning electron microscopy, and X-ray diffraction. The synthesized Cd MONTs exhibited high thermal stability (385 degrees C) and excellent extraction performance toward PCBs. The important conditions were optimized systematically by the response surface method. Under the optimal conditions, the new fiber achieved high enrichment factors (938-3417), low limits of detection (1.80-8.73 pg L-1), and wide linearity (10-5000 pg L-1). The method developed was used in ultratrace-level analysis of PCBs in seawater samples, with satisfactory results for each sample. PMID- 27704174 TI - CFTR pharmacology. AB - CFTR protein is an ion channel regulated by cAMP-dependent phosphorylation and expressed in many types of epithelial cells. CFTR-mediated chloride and bicarbonate secretion play an important role in the respiratory and gastrointestinal systems. Pharmacological modulators of CFTR represent promising drugs for a variety of diseases. In particular, correctors and potentiators may restore the activity of CFTR in cystic fibrosis patients. Potentiators are also potentially useful to improve mucociliary clearance in patients with chronic obstructive pulmonary disease. On the other hand, CFTR inhibitors may be useful to block fluid and electrolyte loss in secretory diarrhea and slow down the progression of polycystic kidney disease. PMID- 27704176 TI - Real-time monitoring of oxidative injury of vascular endothelial cells and protective effect of quercetin using quartz crystal microbalance. AB - The adhesion, spreading, and proliferation of human umbilical vein endothelial cell line (HUVEC-C) cells, on a gold electrode were monitored using quartz crystal microbalance (QCM) measurements. The viscodensity effect caused by the normal action of the cells led to a decrease of the resonant frequency and increase of the motional resistance. The oxidative injury of HUVEC-C cells appeared immediately with the addition of H2O2, exhibiting the decline of cellular spreading area and cell coverage on the electrode surface and resulting in inverted QCM responses. The injured extent of the cells was found to be related to the content of H2O2. It is found that 0.05 mM quercetin added beforehand in the growth medium could remove completely the oxidative action of 1.0 mM H2O2. Quercetin with increased dosage still exerted a partial protective effect on HUVEC-C cells against oxidative injury induced by 2.5 mM H2O2. The microscope observations, electrochemical measurements, and MTT analysis validate the QCM assay results, indicating that quercetin is a valuable flavonoid anti oxidant in the precaution and treatment for the oxidative injury of vascular endothelium.

PMID- 27704178 TI - Study of in-vitro metabolism of selected antibiotic drugs in human liver microsomes by liquid chromatography coupled with tandem mass spectrometry. AB - High performance liquid chromatography coupled with triple-quadrupole mass spectrometry was applied in the determination of in vitro metabolism products of selected antibiotic drugs (cefotaxime, ciprofloxacin, fluconazole, gentamicin, clindamycin, linezolid, and metronidazole). The analytes were separated on a reversed phase C18 column, with acetonitrile and 0.1 % aqueous formic acid as the mobile phase. Tandem mass spectrometry with positive electrospray ionization was used to facilitate the structural characterization of the potential metabolites. Metabolism studies on human liver microsomes were performed via cytochromes P450 (phase I) and via NADPH/UDP-glucuronosyltransferase (phase II) mediated reactions. LC-MS/MS experiments allowed potential metabolite peaks, including sum formulae suggestions, to be identified; high resolution MS/MS experiments led to the identification of various oxidative and reductive modifications of target compounds in phase I biotransformation, and conjugation products with glucuronic acid in phase II reactions. A total of 11 potential metabolites and their proposed structures were characterized during the incubation of human liver microsomes by comparing their retention times and spectral patterns with those of the parent drug. Dehydrogenation and reactions of side chains such as hydroxylation and hydrolysis of ester bonds constituted the major metabolic pathways. Finally, LC-MS/MS spectrometry was revealed to be a suitable analytical tool to procure a feasible analytical base for the envisioned in vivo experiments.

AB - KEY MESSAGE: Using map-based cloning, we delimited the Ms - cd1 gene responsible for the male sterile phenotype in B. oleracea to an approximately 39-kb fragment. Expression analysis suggests that a new predicted gene, a homolog of the Arabidopsis SIED1 gene, is a potential candidate gene. A dominant genic male sterile (DGMS) mutant 79-399-3 in Brassica oleracea (B. oleracea) is controlled by a single gene named Ms-cd1, which was genetically mapped on chromosome C09. The derived DGMS lines of 79-399-3 have been successfully applied in hybrid cabbage breeding and commercial hybrid seed production of several B. oleracea cultivars in China. However, the Ms-cd1 gene responsible for the DGMS has not been identified, and the molecular basis of the DGMS is unclear, which then limits its widespread application in hybrid cabbage seed production. In the present study, a large BC9 population with 12,269 individuals was developed for map-based cloning of the Ms-cd1 gene, and Ms-cd1 was mapped to a 39.4-kb DNA fragment between two InDel markers, InDel14 and InDel24. Four genes were identified in this region, including two annotated genes based on the available B. oleracea annotation database and two new predicted open reading frames (ORFs). Finally, a newly predicted ORF designated Bol357N3 was identified as the candidate of the Ms-cd1 gene. These results will be useful to reveal the molecular mechanism of the DGMS and develop more practical DGMS lines with stable male sterility for hybrid seed production in cabbage. PMID- 27704180 TI - A simple method for isolation and construction of markerless cyanobacterial mutants defective in acyl-acyl carrier protein synthetase. AB - Cyanobacterial mutants defective in acyl-acyl carrier protein synthetase (Aas) secrete free fatty acids (FFAs) into the external medium and hence have been used for the studies aimed at photosynthetic production of biofuels. While the wild type strain of Synechocystis sp. PCC 6803 is highly sensitive to exogenously added linolenic acid, mutants defective in the aas gene are known to be resistant to the externally provided fatty acid. In this study, the wild-type Synechocystis cells were shown to be sensitive to lauric, oleic, and linoleic acids as well, and the resistance to these fatty acids was shown to be enhanced by inactivation of the aas gene. On the basis of these observations, we developed an efficient method to isolate aas-deficient mutants from cultures of Synechocystis cells by counter selection using linoleic acid or linolenic acid as the selective agent. A variety of aas mutations were found in about 70 % of the FFA-resistant mutants thus selected. Various aas mutants were isolated also from Synechococcus sp. PCC 7002, using lauric acid as a selective agent. Selection using FFAs was useful also for construction of markerless aas knockout mutants from Synechocystis sp. PCC 6803 and Synechococcus sp. PCC 7002. Thus, genetic engineering of FFA producing cyanobacterial strains would be greatly facilitated by the use of the FFAs for counter selection. PMID- 27704181 TI - Reduction of ammonia and lactate through the coupling of glutamine synthetase selection and downregulation of lactate dehydrogenase-A in CHO cells. AB - Chinese hamster ovary (CHO) cell cultivation for production of therapeutic proteins is accompanied by production of metabolic wastes, mostly ammonia and lactate. To reduce ammonia production, the glutamine synthetase (GS) system was used to develop therapeutic monoclonal antibody (mAb)-producing CHO cells (SM 0.025). Additionally, the lactate dehydrogenase-A (LDH-A) was downregulated with shRNA to reduce lactate production in SM-0.025. The resulting mAb-producing cell lines (#2, #46, and #52) produced less ammonia than the host cell line during the exponential phase due to GS protein overexpression. LDH-A downregulation in SM 0.025 not only reduced lactate production but also further reduced ammonia production. Among the three LDH-A-downregulated clones, clone #2 had the highest mAb production along with significantly reduced specific lactate and ammonia production rates compared to those in SM-0.025. Waste reduction increased the galactosylation level of N-glycosylation, which improved mAb quality. LDH-A downregulation was also successfully applied to the host cell lines (CHO K1 and GS knockout CHO-K1). However, LDH-A downregulated host cells could not survive the pool-selection process wherein glutamine was excluded and methionine sulfoximine was added to the media. Taken together, LDH-A downregulation in the mAb-producing cell line generated with the GS system successfully reduced both ammonia and lactate levels, improving mAb galactosylation. However, LDH-A downregulation could not be applied to host cell lines because it hampered the selection process of the GS system. PMID- 27704182 TI - Characterization of LnmO as a pathway-specific Crp/Fnr-type positive regulator for leinamycin biosynthesis in Streptomyces atroolivaceus and its application for titer improvement. AB - The cyclic adenosine monophosphate (cAMP) receptor protein/fumarate and nitrate reductase regulatory protein (Crp/Fnr) family of transcriptional regulators are pleiotropic transcriptional regulators that control a broad range of cellular functions. Leinamycin (LNM) is a potent antitumor antibiotic produced by Streptomyces atroolivaceus S-140. We previously cloned and characterized the lnm biosynthetic gene cluster from S. atroolivaceus S-140. We here report inactivation of lnmO in S. atroolivaceus S-140 and overexpression of lnmO in the S. atroolivaceus S-140 wild-type and ?lnmE mutant SB3033 to investigate its role in LNM biosynthesis. Bioinformatics analysis revealed LnmO as the only regulator within the lnm gene cluster, exhibiting high sequence similarity to known Crp/Fnr family regulators. The inactivation of lnmO in S. atroolivaceus S-140 completely abolished LNM production but caused no apparent morphological changes, supporting that LnmO is indispensable and specific to LNM biosynthesis. Overexpression of lnmO in S. atroolivaceus S-140 and SB3033 resulted in three- and fourfold increase in LNM and LNM E1 production, respectively, supporting that LnmO acts as a positive regulator. While all of the Crp/Fnr family regulators studied to date appeared to be pleiotropic, our results support LnmO as the first Crp/Fnr family regulator that is pathway-specific. LnmO joins the growing list of regulators that could be exploited to improve secondary metabolite production in Streptomyces. Engineered strains overproducing LNM and LNM E1 will facilitate further mechanistic studies and clinical evaluation of LNM and LNM E1 as novel anticancer drugs. PMID- 27704183 TI - Autoimmune arthritis deteriorates bone quantity and quality of periarticular bone in a mouse model of rheumatoid arthritis. AB - : This study showed that autoimmune arthritis induces especially severe osteoporosis in the periarticular region adjacent to inflamed joints, suggesting that arthritis increases the fragility fracture risk near inflamed joints, which is frequently observed in patients with RA. INTRODUCTION: Periarticular osteoporosis near inflamed joints is a hallmark of early rheumatoid arthritis (RA). Here we show that rheumatic inflammation deteriorates the bone quality and bone quantity of periarticular bone, thereby decreasing bone strength and toughness in a mouse model of RA. METHODS: Female BALB/c mice and SKG mice, a mutant mouse model of autoimmune arthritis on the BALB/c background, were used. At 12 weeks of age, BALB/c mice underwent either Sham surgery or bilateral ovariectomy (OVX), and SKG mice underwent intraperitoneal injection of mannan to induce arthritis. Eight weeks later, the mice were killed and the femurs and tibias were subjected to micro-computed tomography, Fourier transform infrared (FTIR) spectroscopic imaging, X-ray diffraction, histology, and mechanical testing. RESULTS: SKG mice developed significant trabecular bone loss in both the distal metaphysis of the femur and the lumbar vertebral body, but the extent of the bone loss was more severe in the distal metaphysis. Neither SKG nor OVX mice exhibited changes in the geometry and matrix properties of the diaphysis of the femur, whereas SKG mice, but not OVX mice, did exhibit changes in these properties in the distal metaphysis of the femur. Bone strength and fracture toughness of the distal metaphysis of the tibia adjacent to the inflamed ankle joint were significantly decreased in SKG mice. CONCLUSIONS: Autoimmune arthritis induces periarticular osteoporosis, characterized by deterioration of cortical bone geometry and quality as well as by trabecular bone loss, leading to severe bone fragility in periarticular bone adjacent to inflamed joints. PMID- 27704184 TI - Mini-percutaneous nephrolithotomy for stones in anomalous-kidneys: a prospective study. AB - To evaluate safety and efficacy of minipercutaneous nephrolithotomy (Mini-PNL) in management of stones in different types of renal anomalies. Patients with stones >=2 cm or SWL-resistant stones in anomalous-kidneys treated by Mini-PNL between March 2010 and September 2012 were included prospectively. Mini-PNL was done under regional anesthesia in prone position with fluoroscopic guidance through 18 Fr sheath using semirigid ureteroscope (8.5/11.5 Fr) and pneumatic lithotripter. All patients were followed-up for 2-3 years. Stone-free rate was defined as absence of residual fragments >=2 mm. Student-T, Mann-Whitney, Chi square (chi 2), Fisher-exact, one way ANOVA or Kruskal-Wallis test were used for analysis. Mini-PNL was performed for 59 patients (20 horseshoe, 15 malrotated, 7 polycystic, 13 duplex and 4 ectopic pelvic-kidneys). Mean age was 40.18 +/- 12.75 (14-78) years. Mean stone burden was 31.72 +/- 21.43 (7.85-141.3) mm2. Two tracts were required in 7 (11.9 %) patients. Tubeless Mini-PNL with double-J insertion was performed in all patients except two. Operative time was 50.17 +/- 18.73 (15 105) min. Hemoglobin loss was 0.44 +/- 0.30 (0-1.4) g/dL. Complications were reported in 15 (25.4 %) patients. No pleural injury, sepsis, perinephric collection or renal-pelvis perforation were reported. Stone-free rate was 89.8 % (converted to open-surgery in one patient, second-look PNL in two patients, auxiliary SWL in three patients). Stone-free rate improved to 98.3 % after retreatment and auxiliary SWL. Site of puncture was mostly upper calyceal in horseshoe-kidney (80 %), mid calyceal in polycystic-kidney (85.7 %) and lower calyceal in duplex-kidney (46.2 %). Punctures were also significantly infracostal in horseshoe-kidney (100 %) and supracostal in both duplex (53.8 %) and malrotated-kidneys (66.7 %). Mini-PNL is safe for management of stones in anomalous-kidney with SFR comparable to standard-PNL but with less complications. PMID- 27704185 TI - Emerging Concern from Short-Term Textile Leaching: A Preliminary Ecotoxicological Survey. AB - Textile dyes and their residues gained growing attention worldwide. Textile industry is a strong water consumer potentially releasing xenobiotics from washing and rinsing procedures during finishing processes. On a decentralised basis, also final consumers generate textile waste streams. Thus, a procedure simulating home washing with tap water screened cotton textiles leachates (n = 28) considering physico-chemical (COD, BOD5, and UV absorbance) and ecotoxicological data (Daphnia magna, Pseudokirchneriella subcapitata and Lepidium sativum). Results evidenced that: (i) leachates presented low biodegradability levels; (ii) toxicity in more than half leachates presented slight acute or acute effects; (iii) the remaining leachates presented "no effect" suggesting the use of green dyes/additives, and/or well established finishing processes; (iv) no specific correlations were found between traditional physico-chemical and ecotoxicological data. Further investigations will be necessary to identify textile residues, and their potential interactions with simulated human sweat in order to evidence potential adverse effects on human health. PMID- 27704186 TI - Effect of Pretilachlor on Soil Enzyme Activities in Tropical Rice Soil. AB - Pretilachlor treatments, namely, recommended dose at 600 g a.i. ha-1 (RD), double the recommended dose at 1200 g a.i. ha-1 (2RD), ten times of the recommended dose at 6000 g a.i. ha-1 (10RD) along with control, were used to study the effects of pretilachlor on soil enzymes in tropical rice soil. Pretilachlor, at recommended dose completely dissipated 30 days after herbicide application. Twenty days after herbicide application, the dehydrogenase activity was inhibited up to 27 %, 28 % and 40 % of initial values of RD, 2RD and 10RD treatments, respectively. Increase in fluorescein diacetate hydrolase activity was observed during the first 25 days post herbicide application up to 29 %, 36 % and 10 % of initial values of RD, 2RD and 10RD treatments, respectively. beta-Glucosidase activity in the experiment did not provide a specific trend. In general, urease and acid phosphatase activities were not influenced by pretilachlor application. There were significant differences in alkaline phosphatase activities among the treatments until 25 days after herbicide application. Hence, pretilachlor may cause short term transitory changes in soil enzyme parameters. However, it has negative impact on soil enzymes at very high dose. PMID- 27704187 TI - Long-Term Survey of Cadmium and Lead Contamination in Japanese Black Bears Captured in Iwate Prefecture, Japan. AB - Cadmium and lead were measured in liver and kidney samples of 242 Japanese black bears (Ursus thibetanus japonicus) captured from 1999 to 2014 from two local populations in Japan. The median concentration of cadmium was 0.54 (mean: 0.80) mg/kg-w.w. in liver and 7.7 (mean: 11.8) mg/kg-w.w. in kidney. The median concentration of lead was 0.24 (mean: 0.40) and 0.21 (mean: 0.32) mg/kg-w.w. in liver and kidney, respectively. Bears in the Kita-ou local population had higher concentrations of cadmium and lead than those in the Kitakami Highlands local population. No chronological change was observed in cadmium levels in tissues, but the percentage of bears whose lead levels exceeded 0.5 mg/kg-w.w. has been decreasing in recent years. Countermeasures against lead poisoning in wildlife, which were instituted in 2002, may have contributed to the decrease in lead contamination of the Japanese black bear. PMID- 27704188 TI - Toxicity of CuO Nanoparticles to Structure and Metabolic Activity of Allium cepa Root Tips. AB - Roots of Allium cepa were exposed to six CuO NPs suspensions (0, 5, 10, 20, 40, 80 mg L-1) in this study. Results revealed that with the increase of CuO NPs concentration, the Cu content in roots increased significantly. Compared to control, onion roots treated with CuO NPs (except 5 mg L-1 suspension) grew slowly after 24 h. The surface of the root cap and meristematic zone were obviously damaged. The apical meristem of roots treated by 10 mg L-1 and above concentrations stopped division. The nucleus of meristematic cells deformed, and nucleoli number increased. The plasmolysis occurred, and the cell membrane and nuclear membrane fractured. With the increase of CuO NPs concentration, the MDA content increased, and the root activity decreased. When dealt with 80 mg L-1 CuO NPs for 72 h, onion roots appeared to be corroded. PMID- 27704189 TI - Sublethal Effects of Chlorine-Free Kraft Mill Effluents on Daphnia magna. AB - The implementation of elemental chlorine-free (ECF) bleaching methods has drastically reduced the aquatic toxicity of Kraft mill effluents during the last decade. However, the residual toxicity of Kraft mill effluents is still a potential concern for the environment, even when subjected to secondary wastewater treatment. The aim of this study is characterize potential sublethal effects of ECF Kraft mill effluents using Daphnia magna as model species. D. magna exposed towards increasing concentration of ECF Kraft mill effluent showed a significant, dose-dependent reduction in feeding. Conversely, post-feeding assay, life history, and allometric growth analyses showed stimulatory, rather than inhibitory effects in exposed animals at low concentrations, while high concentrations of ECF Kraft mill effluents reduced their reproductive output. These results suggest a hormetic effect in which moderate concentrations of the effluent had a stimulatory effect with higher concentrations causing inhibition in some variables. PMID- 27704190 TI - Chromium Displacement in Subtropical Soils Fertilized with Hydrolysed Leather: A Laboratory Study. AB - Prolonged use of biosolids with high metal content may result in diffuse pollution across large regions, especially if such ions can move freely through the soil profile and reach underground water sources. The objective of this study was to verify whether Cr added to the soil surface in the form of hydrolysed leather or a soluble salt would migrate over significant distances in four subtropical soils differing in physical, chemical and mineralogical properties. Horizontal and vertical mobility were assessed in Petri dishes and small pots, respectively, using low (12 mg kg-1 soil) and high Cr levels (150 mg kg-1 soil) added to the soil surface. Irrespective of concentration, soluble Cr salts were found to move more easily in soils with low organic matter and clay content. Contrarily, Cr added as hydrolysed leather exhibited negligible mobility and tended to accumulate in the vicinity of application.

PMID- 27704193 TI - Long-term follow-up and role of FDG PET in advanced pancreatic neuroendocrine patients treated with 177Lu-D OTATATE. AB - PURPOSE: Lu-DOTATATE (Lu-PRRT) is a valid therapeutic option in differentiated pancreatic neuroendocrine tumors (P-NETs). FDG PET seems to be an important prognostic factor in P-NETs. We evaluated the efficacy of Lu-PRRT and the role of FDG PET in 60 patients with advanced P-NETs. METHODS: From March 2008 to June 2011, 60 consecutive patients with P-NETs were enrolled in the study. Follow-up lasted until March 2016. Eligible patients were treated with two different total cumulative activities (18.5 or 27.8 GBq in 5 cycles every 6-8 weeks), according to kidney and bone marrow parameters. RESULTS: Twenty-eight patients received a mean full activity (FA) of 25.9 GBq and 32 a mean reduced activity (RA) of 18.5 GBq. The disease control rate (DCR), defined as the sum of CR+PR+SD was 85.7 % in the FA group and 78.1 % in the RA group. Median progression-free survival (mPFS) was 53.4 months in the FA group and 21.7 months in the RA group (P = 0.353). Median overall survival (mOS) was not reached (nr) in FA patients and was 63.8 months in the RA group (P = 0.007). Fifty-five patients underwent an FDG PET scan before Lu-PRRT, 32 (58 %) showing an increased FDG uptake in tumor sites. mPFS was 21.1 months in FDG PET-positive patients and 68.7 months in the FDG PET negative group (P < 0.0002), regardless of the total activity administered. CONCLUSION: Both FA and RA are active in patients undergoing Lu-PRRT. However, an FA of 27.8 GBq of Lu-PRRT prolongs PFS and OS compared to an RA of 18.5 GBq. Our results indicate that FDG PET is an independent prognostic factor in this patient setting. PMID- 27704194 TI - [18F]FDG PET accurately differentiates infected and non-infected non-unions after fracture fixation. AB - PURPOSE: Complete fracture healing is crucial for good patient outcomes. A major complication in the treatment of fractures is non-union. The pathogenesis of non unions is not always clear, although implant-associated infections play a significant role, especially after surgical treatment of open fractures. We aimed to evaluate the value of [18F]FDG PET in suspected infections of non-union fractures. METHODS: We retrospectively evaluated 35 consecutive patients seen between 2000 and 2015 with suspected infection of non-union fractures, treated at a level I trauma center. The patients underwent either [18F]FDG PET/CT (N = 24), [18F]FDG PET (N = 11) plus additional CT (N = 8), or conventional X-ray (N = 3). Imaging findings were correlated with final diagnosis based on intraoperative culture or follow-up. RESULTS: In 13 of 35 patients (37 %), infection was proven by either positive intraoperative tissue culture (N = 12) or positive follow-up (N = 1). [18F]FDG PET revealed 11 true-positive, 19 true-negative, three false positive, and two false-negative results, indicating sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of 85 %, 86 %, 79 %, 90 %, and 86 %, respectively. The SUVmax was 6.4 +/- 2.7 in the clinically infected group and 3.0 +/- 1.7 in the clinically non-infected group (p <0.01). The SUVratio was 5.3 +/- 3.3 in the clinically infected group and 2.6 +/- 1.5 in the clinically non-infected group (p <0.01). CONCLUSION: [18F]FDG PET differentiates infected from non-infected non-unions with high accuracy in patients with suspected infections of non-union fractures, for whom other clinical findings were inconclusive for a local infection. [18F]FDG PET should be considered for therapeutic management of non-unions. PMID- 27704195 TI - Tracheocutaneous Fistula Closure: Comparison of Rhomboid Flap Repair with Z Plasty Repair in a Case Series of 40 Patients. AB - INTRODUCTION: Tracheocutaneous fistula (TCF) is one of the recognized sequelae of a long-term tracheostomy resulting from mucocutaneous overgrowth which prevents closure of the artificial lumen at the site of tracheostomy. Primary closure of TCF has disappointing results and may lead to complications like pneumothorax, pneumomediastinum, cervicofacial subcutaneous emphysema, and depressed scar. OBJECTIVE: To compare TCF repair using fistulectomy followed by rhomboid flap versus fistulectomy followed by Z plasty repair. METHODS: In this prospective study, 40 patients of either sex with persistent TCF were included. All patients were randomly divided into two groups. Group I had 20 patients who underwent TCF repair using a technique in which fistulectomy was done followed by its closure in layers, and finally closing the defect using a rhomboid flap. The remaining 20 were included in group II who underwent TCF repair using a technique in which fistulectomy was done followed by layered closing, and final closure of the defect was done using Z plasty. The follow-up period was 3 months. RESULTS: Out of 40 patients, all but 8 experienced a successful outcome without any complications, and complete aesthetic satisfaction, with improvement in phonation, and no soiling of clothes with mucus or sputum. The 8 unsuccessful patients belonged to group II (Z plasty group). CONCLUSION: Both techniques have been described in the literature and are proven to give good results. Our study emphasizes the fact that in our experience, the rhomboid flap was a better alternative for TCF repair than Z plasty.

PMID- 27704196 TI - Scarless Epicanthoplasty and Concomitant Double Eyelidplasty in Chinese Eyelids. AB - BACKGROUND: The presence of mild or moderate medial epicanthus is typical in Asian patients. Numerous epicanthoplasty techniques have been described previously. However, these methods usually leave obvious scars in the medial canthal area. The aim of this report is to introduce a novel epicanthoplasty technique and a concomitant double eyelidplasty which avoid leaving scars in the medial canthal region. METHODS: From July 2013 to July 2015, 252 patients received epicanthoplasty and concomitant double eyelidplasty with this new technique. The medial epicanthus was corrected through the medial end of the eyelid crease incision. One hundred eighteen of these patients were followed up for 3-24 months (8 months in average). The preoperative and postoperative interepicanthal distances were measured at pre, 3 and 6 months post-operation. The aesthetic results were evaluated with patient visual analog scale (VAS) scores. RESULTS: The average intercanthal distance significantly decreased 3 months after the operation (32.7 +/- 2.3 mm vs 36.5 +/- 2.6 mm, p < 0.05, paired t test). Little retraction was noticed at 6 months after the operation (33.0 +/- 2.4 vs 32.7 +/- 2.3 mm, p < 0.05, paired t test). The mean patient VAS score associated with satisfaction of overall outcome was 4.2 at 6 months after operation (range 2.5-5.0). CONCLUSION: This new method provides an effective way to correct the medial epicanthus without leaving any scar in the medial canthal region. Patients with mild to moderate medial epicanthus are good candidates for this procedure. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

PMID- 27704197 TI - A Simple and Effective Technique of Breast Remodelling After Conserving Surgery for Lower Quadrants Breast Cancer. AB - BACKGROUND: Quadrantectomy is an oncologically safe procedure for the treatment of early-stage breast cancer, but it often results in poor aesthetic outcomes such as breast shape deformity, which is more visible if the tumour is located in the lower pole. We recommend the use of the transverse incision, which retains the oncological advantages of the quadrantectomy while leading to better aesthetical results. METHOD: We evaluated the clinical results of 24 patients with breast cancer who underwent quadrantectomy of the lower breast pole and volume replacement with remodelling through three posterior scorings from January 2012 to January 2014, with cosmetic evaluations performed according to the criteria set by the Japanese Breast Cancer Society. RESULTS: Minimum follow-up after surgery was 2 years, with an average of 28.4 months. Among treated patients, the percentage of complications was extremely low and the degree of satisfaction fairly good. Moreover, the assessment of the medical team matched patient self-assessments. CONCLUSION: Immediate breast reconstruction of a defect performed after a quadrantectomy of the lower breast pole using the "posterior scoring technique" provided better cosmetic results compared to the transposition of residual breast tissue. This technique provides reliable and reproducible results, and it also appears to be rather successful on patients with small moderate breasts in the absence of a certain degree of ptosis, therefore increasing its already considerable appeal.

PMID- 27704198 TI - Diagnostic value of transmural perfusion ratio derived from dynamic CT-based myocardial perfusion imaging for the detection of haemodynamically relevant coronary artery stenosis. AB - OBJECTIVES: To investigate the additional value of transmural perfusion ratio (TPR) in dynamic CT myocardial perfusion imaging for detection of haemodynamically significant coronary artery disease compared with fractional flow reserve (FFR). METHODS: Subjects with suspected or known coronary artery disease were prospectively included and underwent a CT-MPI examination. From the CT-MPI time-point data absolute myocardial blood flow (MBF) values were temporally resolved using a hybrid deconvolution model. An absolute MBF value was measured in the suspected perfusion defect. TPR was defined as the ratio between the subendocardial and subepicardial MBF. TPR and MBF results were compared with invasive FFR using a threshold of 0.80. RESULTS: Forty-three patients and 94 territories were analysed. The area under the receiver operator curve was larger for MBF (0.78) compared with TPR (0.65, P = 0.026). No significant differences were found in diagnostic classification between MBF and TPR with a territory based accuracy of 77 % (67-86 %) for MBF compared with 70 % (60-81 %) for TPR. Combined MBF and TPR classification did not improve the diagnostic classification. CONCLUSIONS: Dynamic CT-MPI-based transmural perfusion ratio predicts haemodynamically significant coronary artery disease. However, diagnostic performance of dynamic CT-MPI-derived TPR is inferior to quantified MBF and has limited incremental value. KEY POINTS: * The transmural perfusion ratio from dynamic CT-MPI predicts functional obstructive coronary artery disease * Performance of the transmural perfusion ratio is inferior to quantified myocardial blood flow * The incremental value of the transmural perfusion ratio is limited. PMID- 27704199 TI - Evaluation of Chondrocalcinosis and Associated Knee Joint Degeneration Using MR Imaging: Data from the Osteoarthritis Initiative. AB - OBJECTIVES: To evaluate the ability of different MRI sequences to detect chondrocalcinosis within knee cartilage and menisci, and to analyze the association with joint degeneration. METHODS: Subjects with radiographic knee chondrocalcinosis (n = 90, age 67.7 +/- 7.3 years, 50 women) were selected from the Osteoarthritis Initiative and matched to controls without radiographic chondrocalcinosis (n = 90). Visualization of calcium-containing crystals (CaC) was compared between 3D T1-weighted gradient-echo (T1GE), 3D dual echo steady state (DESS), 2D intermediate-weighted (IW), and proton density (PD)-weighted fast spin-echo (FSE) sequences obtained with 3T MRI and correlated with a semiquantitative CaC score obtained from radiographs. Structural abnormalities were assessed using Whole-Organ MRI Score (WORMS) and logistic regression models were used to compare cartilage compartments with and without CaC. RESULTS: Correlations between CaC counts of MRI sequences and degree of radiographic calcifications were highest for GE (rT1GE = 0.73, P < 0.001; rDESS = 0.68, P < 0.001) compared to other sequences (P > 0.05). Meniscus WORMS was significantly higher in subjects with chondrocalcinosis compared to controls (P = 0.005). Cartilage defects were significantly more frequent in compartments with CaC than without (patella: P = 0.006; lateral tibia: P < 0.001; lateral femur condyle: P = 0.017). CONCLUSIONS: Gradient-echo sequences were most useful for the detection of chondrocalcinosis and presence of CaC was associated with higher prevalence of cartilage and meniscal damage. KEY POINTS: * Magnetic resonance imaging is useful for assessing burden of calcium-containing crystals (CaC). * Gradient-echo sequences are superior to fast spin echo sequences for CaC imaging. * Presence of CaC is associated with meniscus and cartilage degradation. PMID- 27704200 TI - Prominent cerebral veins on susceptibility-weighted imaging (SWI) in pulmonary embolism. AB - OBJECTIVES: Clinical applications of susceptibility-weighted imaging (SWI) are increasing steadily. The aim of this study is to investigate the appearance of cerebral veins on SWI, which is very sensitive to the deoxyhaemoglobin level in vessels, in pulmonary embolism (PE). METHODS: The cranial SWI images of 19 patients with PE and 22 controls from September 2013 through March 2016 were retrospectively examined for the presence of prominent cerebral veins. MRI findings were correlated with blood oxygen levels. RESULTS: 12 of 19 patients with PE had hypoxemia and SWI images of 11 of these hypoxemic patients depicted prominent cerebral veins in the form of increased number, diameter, and elongation. The mean PaO2 and SaO2 in these patients were 48.5 +/- 9.1 mmHg and 75.2 +/- 8.0 %, respectively. There was a significant correlation between the presence of prominent veins on SWI and hypoxemia (p < 0.05). Of the 7 patients with normal blood oxygen pressure and saturation, 1 also showed an augmented appearance of cerebral veins on SWI. CONCLUSIONS: In the presence of neurological symptoms suggestive of an intracranial pathology in patients with PE, a SWI added to the conventional MRI sequences may predict hypoxemia and exclude other intracranial pathologies. KEY POINTS: * Patients with PE may exhibit nonspecific symptoms suggestive of an intracranial pathology. * A cerebral venous prominence on SWI should raise the suspicion of hypoxia. * SWI-mIP images intensify the appearance of veins and help distinguish other hypointensities. PMID- 27704201 TI - Technical feasibility and tissue reaction after silicone-covered biodegradable magnesium stent insertion in the oesophagus: a primary study in vitro and in vivo. AB - OBJECTIVES: Determine the feasibility of and tissue response to biodegradable magnesium-silicone stent insertion into the oesophagus of rabbits. METHODS: Mechanical compression-recovery and degradation behaviours of the stents were investigated in vitro. Thirty rabbits were randomly divided into a magnesium silicone stent group (n = 15) that received stent insertion into the lower 1/3 of the oesophagus under fluoroscopic guidance and a control group (n = 15). Oesophagography was performed at 1, 2 and 4 weeks. Five rabbits in each group were euthanized at each time point for histological examination. RESULTS: Magnesium-silicone stents showed good flexibility and elasticity, and degraded more slowly than bare stents at pH 4.0 and 7.4. All stent insertions were well tolerated. The oesophageal diameters at 1, 2 and 4 weeks were 9.7 +/- 0.7, 9.6 +/ 0.8 and 9.6 +/- 0.5 mm, respectively (vs. 9.2 +/- 0.8 mm before intervention; P > 0.05). Stent migration occurred in six rabbits (one at 1 week, one at 2 and four at 4). Microscopy demonstrated dilation of the oesophageal wall within 1 week of insertion. Oesophageal injury and collagen deposition following stent insertion were similar to control (P > 0.05). CONCLUSIONS: Oesophageal magnesium silicone stent insertion was feasible and provided reliable support for 2 weeks without causing oesophageal injury or collagen deposition. KEY POINTS: * Mg stent provided apparently adequate radial force and silicone membrane reduced magnesium biodegradation * Stent insertion provided good support for at least 2 weeks before biodegradation * Stenting effectively resulted in oesophageal wall remodelling, without demonstrable injury. PMID- 27704202 TI - Female urethral stricture: a contemporary series. AB - PURPOSE: To report the etiology, presenting symptoms and outcomes of the different treatments performed in female patients with recurrent urethral stricture. MATERIALS AND METHODS: Twenty-six patients with refractory LUTS were diagnosed with a urethral stricture. The symptoms, the treatment performed and the outcomes were prospectively recorded. Sixteen patients were treated with a urethroplasty using a buccal mucosal graft (BMG) in 14 cases (54 %) and a vaginal flap in 2 (8 %). Urethral dilatation, optical urethrotomy and meatoplasty were performed in 8 (31 %), 1 (3.8 %) and 1 (3.8 %) patients, respectively. RESULTS: Strictures were idiopathic in 11 patients (42 %). Previous urethral instrumentation and traumatic vaginal delivery were the commonest causes of urethral stricture (42 and 15 %, respectively). The most frequent symptoms were reduced flow (93 %), detrusor overactivity (50 %) and UTIs (42 %). The stricture was cured in 93 % of patients treated with a BMG urethroplasty and in all the patients in which a vaginal flap urethroplasty was performed. In the same group, the improvement in urethral pain was observed in the 67 and the 88 % of patients were cured from recurrent UTIs. All the patients treated with urethral dilatation needed further dilatations; hence, the cure of the stricture was achieved in none of them. Improvement in urethral pain, UTIs and detrusor activity was not recorded in the latter group. CONCLUSION: Urethroplasty in its various forms has demonstrated in the present series the highest cure rate for the treatment of recurrent urethral stricture. PMID- 27704203 TI - Ileal pouch-anal anastomosis for ulcerative colitis: a Canadian institution's experience. AB - BACKGROUND: We aimed to summarize the outcomes of ulcerative colitis (UC) patients receiving an ileal pouch-anal anastamosis (IPAA) over an 11-year period at a high-volume Canadian inflammatory bowel disease (IBD) center. METHODS: A retrospective chart review was performed for subjects with UC who underwent IPAA between 2002 and 2013. Patient charts were reviewed for demographic data, clinical characteristics, preoperative medical treatment, and surgical outcomes. Univariate and multivariate logistic regression modeling were used to determine significant factors in postoperative outcomes. RESULTS: Seven hundred fifty-eight were included from the IBD database. The median age at the time of surgery was 37.1 (+/-12.1). Mean preoperative disease duration was 8.1 years (+/-8.7). Three hundred sixty-nine patients (48.7 %) had systemic corticosteroids (>15 mg/day) within 30 days prior to surgery. Of these, 286 patients had high dose (>30 mg/day) corticosteroids within 7 days of their first surgery. One hundred nine (14.0 %) IPAA procedures were performed laparoscopically. Pelvic pouches were created in traditional 2 (n = 460) and 3 (n = 285) stages; the remainder (n = 13) was performed in non-traditional staged operations. Early complications, defined as occurring within the same stay in hospital, consisted of pelvic abscess (n = 135, 17.8 %), small bowel obstruction (n = 134, 17.7 %), wound infection (n = 108, 14.3 %), and deep vein thrombosis (n = 33, 4.4 %). The overall pouch leak rate was 92 (12.1 %). There was one death in our study. The median length of stay was 10.3 days (SD6.0). Late complications, defined as occurring after discharge from hospital, consisted of anal stricture (n = 55, 7.3 %), pouch fistula (n = 26, 3.4 %), and functional pouch failure (n = 7, 0.9 %). CONCLUSIONS: IPAA has been found to be a safe and effective method of surgical management of UC patients in a high-volume IBD center. PMID- 27704204 TI - Fixation techniques and stem dimensions in hinged total knee arthroplasty: a finite element study. AB - INTRODUCTION: No evidence-based guidelines are available to determine the appropriate stem length, and whether or not to cement stems in revision total knee arthroplasty (TKA). Therefore, the objective of this study was to compare stresses and relative movement of cemented and uncemented stems of different lengths using a finite element analysis. MATERIALS AND METHODS: A finite element model was created for a synthetic tibia. Two stem lengths (95 and 160 mm) and two types of fixation (cemented or press fit) of a hinged TKA were examined. The average compressive stress distribution in different regions of interest, as well as implant micromotions, was determined and compared during lunge and squat motor tasks. RESULTS: Both long and short stems in revision TKA lead to high stresses, primarily in the region around the stem tip. The presence of cement reduces the stresses in the bone in every region along the stem. Short stem configurations are less affected by the presence of cement than the long stem configuration. Press-fit stems showed higher micromotions compared to cemented stems. CONCLUSIONS: Lowest stresses and micromotion were found for long cemented stems. Cementless stems showed more micromotion and increased stress levels especially at the level of the stem tip, which may explain the clinical phenomenon of stem end pain following revision knee arthroplasty. These findings will help the surgeon with optimal individual implant choice. PMID- 27704205 TI - Complete prevention of radiation-induced dermatitis using topical adrenergic vasoconstrictors. AB - Radiation dermatitis is a commonly occurring, painful, side effect of cancer radiotherapy that causes some patients to withdraw from the radiotherapy course. Our goal was to test and optimize topical application of an adrenergic vasoconstrictor to rat skin in a preclinical test to prevent radiation-induced dermatitis. A radiation dermatitis assay was developed in which 17.2 Gy to a 1.5 * 3.0 cm rectangle on the clipped dorsal back of rats yielded Grade 3 radiation dermatitis over the irradiated area 13 days later. Single, topical applications of each of three adrenergic vasoconstrictors, epinephrine, norepinephrine, or phenylephrine, in various vehicle formulations, doses, and application schedules, were tested to determine their efficacy in preventing radiation dermatitis. Each of the three adrenergic agonists conferred 100 % prevention of radiation dermatitis in linear, dose-dependent manners and their EC50 potencies in preventing radiation dermatitis correlated well with their individual K d association constants for binding to mammalian alpha-adrenergic receptors. Topical vasoconstrictor application as little as 3-12 min before irradiation gave 80-100 % prevention, respectively, of radiation dermatitis. There was a strong correlation between the extent (0-100 %) of skin blanch present in skin immediately before irradiation and prevention of radiation dermatitis scored 13 days after irradiation. The data presented here demonstrate that topical application of adrenergic vasoconstrictors to rat skin before a large, 17.2 Gy, radiation insult confers 100 % protection against radiation dermatitis and support ongoing clinical trials and commercial development of a vasoconstrictor based product to prevent radiotherapy-induced dermatitis.

AB - Multiple sclerosis is a chronic inflammatory disease of the central nervous system characterized by damage to myelin and axons, over time leading to progressive neuronal degeneration and microglial activation. There is still no curative treatment, but during the last 20 years eight different therapies have become available including interferon beta, glatiramer acetate, teriflunomide, dimethyl fumarate, natalizumab, fingolimod, alemtuzumab, mitoxantrone and teriflunomide. Teriflunomide is an immunomodulatory drug that exerts an inhibitory effect on T cell activation in central nervous system of the patients with multiple sclerosis. We determined whether teriflunomide affect the production of interferon-gamma, interleukin-2 and tumor-necrosis-factor-alpha in the QuantiFERON-TB in-Tube-assay. Blood from 24 adults with latent tuberculosis infection was added to one standard set of QuantiFERON tubes and one further set containing teriflunomide. Teriflunomide resulted in a change in QuantiFERON results from positive to negative in four patients with a marked reduction in interferon-gamma. Our data indicated that results from QuantiFERON in patients on teriflunomide therapy should be interpreted with caution. PMID- 27704207 TI - Effects of prebiotics on immune system and cytokine expression. AB - Nowadays, use of prebiotics as feed and food additives has received increasing interest because of the beneficial effects of prebiotics on the health of animals and humans. One of the beneficial effects of prebiotics is stimulation of immune system, which can be direct or indirect through increasing population of beneficial microbes or probiotics, especially lactic acid bacteria and bifidobacteria, in the gut. An important mechanism of action of probiotics and prebiotics, by which they can affect the immune system, is changing the expression of cytokines. The present review tried to summarize the findings of studies that investigated the effects of prebiotics on immune system with focusing on their effects on cytokine expression. Generally, most of reviewed studies indicated beneficial effects for prebiotics in terms of improving immune system, by increasing the expression of anti-inflammatory cytokines, while reducing the expressions of proinflammatory cytokines. However, most of studies mainly considered the indirect effects of prebiotics on the immune system (through changing the composition and population of gut microbiota), and their direct effects still need to be further studied using prebiotics with different degree of polymerization in different hosts. PMID- 27704209 TI - ? PMID- 27704208 TI - Improvement in functional performance with high-speed power training in older adults is optimized in those with the highest training velocity. AB - PURPOSE: To identify whether variability in limb movement velocity during high speed power training (HSPT) may impact physical functioning in older adults. METHODS: 42 older men and women (71.3 +/- 6.6 years) were randomized to lower extremity HSPT (n = 28) or control (CON; n = 14) (Analysis 1) for 12 weeks. A second analysis (Analysis 2) allocated HSPT into high-velocity (n = 14) or low velocity (n = 14) based on a limb movement speed above or below the median average velocity during the 12-week HSPT intervention. Habitual gait speed, maximal gait speed, timed up-and-go, and the short physical performance battery were measured at baseline and 12 weeks. Change scores were compared between HSPT and CON (Analysis 1), and high-velocity, low-velocity, and CON (Analysis 2) using ANCOVA. Statistical significance was accepted at p < 0.05. RESULTS: Analysis 1 There were no group differences in habitual gait speed, maximal gait speed, or timed up-and-go between HSPT and CON (all p > 0.05). Short physical performance battery was greater in HSPT (0.96 +/- 0.19) compared to CON (0.10 +/- 0.26; p = 0.01). Analysis 2 There were no group differences in the change in habitual GS (p = 0.33) among high-velocity, low-velocity and CON. There were significant group differences in the change in maximal GS (p = 0.007), timed up-and-go (p = 0.03), and short physical performance battery (p = 0.03). CONCLUSIONS: There is considerable variation in self-selected maximal limb velocity during HSPT in older adults. In the present cohort, an average limb velocity of 0.88 m/s during HSPT was necessary to ensure optimal improvement in functional performance for older adults, but this threshold will need further investigation. PMID- 27704210 TI - Fat tissues, the brite and the dark sides. AB - Fat tissue is well known for its capacity to store energy and its detrimental role in obesity and metaflammation. However, humans possess different types of fat that have different functions in physiology and metabolic diseases. Apart from white adipose tissue (WAT), the body's main energy storage, there is also brown adipose tissue (BAT) that dissipates energy as a defense against cold and maintains energy balance for the whole body. BAT is present not only in newborns but also in adult humans and its mass correlates with leanness. Moreover, "brown like" adipocytes have been detected in human WAT. These "brown-in-white" (brite) or beige cells can be induced by cold and a broad spectrum of pharmacological substances and, therefore, they are also known as "inducible brown adipocytes." Activation of brown and/or brite adipocytes reduces metabolic diseases, at least in murine models of obesity. Thus, brown/brite adipocytes represent the "brite" side of fat and are potential targets for novel therapeutic approaches for treatment of obesity and obesity-associated diseases. PMID- 27704211 TI - Deep tissue imaging: a review from a preclinical cancer research perspective. AB - This review delves into the rapidly evolving field of deep tissue imaging at cellular resolution, reviewing popular tissue clearing and staining methods in combination with light-sheet fluorescence microscopy (LSFM) including quantification and three-dimensional visualization tools, the field of applications and perspective, particularly with the focus on preclinical cancer research and drug development. The LSFM technique presented here allows an extremely fast optical sectioning for three-dimensional reconstruction of centimeter-sized tissue samples at cellular resolution. However, optical clearing methods are required to receive optical transparent tissue. Application of either tissue autofluorescence, in vivo fluorescence labeling, endogenous fluorescence or ex vivo whole-mount immunolabeling enables three-dimensional in situ visualization of morphological and functional features of unsectioned whole-mount tissue samples. This powerful and innovative imaging technique opens up a new dimension of tissue analysis providing detailed and comprehensive insights into biology. It enables the investigation of normal and pathological tissue features and disease progression and allows precise monitoring of potential therapeutic interventions in intact biological tissue on a cellular level. PMID- 27704212 TI - High mobility group box 1 (HMGB1): dual functions in the cochlear auditory neurons in response to stress? AB - High mobility group box 1 (HMGB1) is a DNA-binding protein that facilitates gene transcription and may act extracellularly as a late mediator of inflammation. The roles of HMGB1 in the pathogenesis of the spiral ganglion neurons (SGNs) of the cochlea are currently unknown. In the present study, we tested the hypothesis that early phenotypical changes in the SGNs of the amikacin-poisoned rat cochlea are mediated by HMGB1. Our results showed that a marked downregulation of HMGB1 had occurred by completion of amikacin treatment, coinciding with acute damage at the dendrite extremities of the SGNs. A few days later, during the recovery of the SGN dendrites, the protein was re-expressed and transiently accumulated within the nuclei of the SGNs. The phosphorylated form of the transcription factor c-Jun (p-c-Jun) was concomitantly detected in the nuclei of the SGNs where it often co-localized with HMGB1, while the anti-apoptotic protein BCL2 was over expressed in the cytoplasm. In animals co-treated with amikacin and the histone deacetylase inhibitor trichostatin A, both HMGB1 and p-c-Jun were exclusively found within the cytoplasm. The initial disappearance of HMGB1 from the affected SGNs may be due to its release into the external medium, where it may have a cytokine-like function. Once re-expressed and translocated into the nucleus, HMGB1 may facilitate the transcriptional activity of p-c-Jun, which in turn may promote repair mechanisms. Our study therefore suggests that HMGB1 can positively influence the survival of SGNs following ototoxic exposure via both its extracellular and intranuclear functions. PMID- 27704214 TI - Management of bone fragments in nonmissile compound depressed skull fractures. AB - BACKGROUND: There is no settled standard of care or even a consensus between neurosurgeons on the replacement of bone fragments in compound depressed skull fractures (CDSF). MATERIALS AND METHODS: This cohort study retrospectively reviewed the patients with nonmissile CDSF who were admitted to our university hospitals from January 2010 to January 2015. Patients who were managed nonoperatively, polytrauma, comatose patients, and CDSF over the air sinuses were excluded from this study. RESULTS: This study includes 87 consecutive patients with nonmissile CDSF who were surgically treated from January 2010 to January 2015. Follow-up varied from 12 to 36 months. All of the 87 patients presented within 1 week after injury; 76 patients (87.35 %) had surgery within the first 72 h of trauma, and these patients had primary bone fragment replacement (after decontamination) with or without miniplates and minimesh. The patients who presented after 72 h of trauma with no wound discharge had their bone fragments autoclaved then replaced. The patients who presented after 72 h of trauma and had pus or serous discharge from the wound had their bone fragments discarded and scheduled for delayed cranioplasty. The long-term infection rate in all patients who had a primary bone fragment replacement in this study is 0 %. CONCLUSIONS: Primary bone fragment replacement (after decontamination) is a safe option in the management of nonmissile CDSF within 72 h of trauma in selected patients. PMID- 27704213 TI - Network analysis of mitonuclear GWAS reveals functional networks and tissue expression profiles of disease-associated genes. AB - While mitochondria have been linked to many human diseases through genetic association and functional studies, the precise role of mitochondria in specific pathologies, such as cardiovascular, neurodegenerative, and metabolic diseases, is often unclear. Here, we take advantage of the catalog of human genome-wide associations, whole-genome tissue expression and expression quantitative trait loci datasets, and annotated mitochondrial proteome databases to examine the role of common genetic variation in mitonuclear genes in human disease. Through pathway-based analysis we identified distinct functional pathways and tissue expression profiles associated with each of the major human diseases. Among our most striking findings, we observe that mitonuclear genes associated with cancer are broadly expressed among human tissues and largely represent one functional process, intrinsic apoptosis, while mitonuclear genes associated with other diseases, such as neurodegenerative and metabolic diseases, show tissue-specific expression profiles and are associated with unique functional pathways. These results provide new insight into human diseases using unbiased genome-wide approaches. PMID- 27704215 TI - Natural occurrence of NS5B inhibitor resistance-associated variants in Brazilian patients infected with HCV or HCV and HIV. AB - Resistance-associated variants (RAVs) represent a challenge to the success of new HCV therapies. The aim of this study was to describe the prevalence of naturally occurring NS5B RAVs in Brazilian direct acting antivirals (DAA)-naive patients infected with HCV genotype 1, or co-infected with HIV. Patient enrollment and sample collection were performed between 2011 and 2013. Using Sanger-based sequencing, 244 sequences were obtained. RAVs detected in HCV-1a sequences were V321A (1.6 %), M414V (1.3 %), A421V (21.4-23.7 %), A421G (1.3 %) and Y448H (1.3 %); and in HCV-1b sequences were L159F (16.1 %), C316N (7.1-16.3 %) and A421V (3.2-6.3 %). Understanding the real RAVs scenario in patients is fundamental to establishing the most effective therapeutic strategy and in minimizing the risks for their selection. PMID- 27704216 TI - Heat-stressed Metarhizium anisopliae: viability (in vitro) and virulence (in vivo) assessments against the tick Rhipicephalus sanguineus. AB - The current study investigated the thermotolerance of Metarhizium anisopliae s.l. conidia from the commercial products Metarril(r) SP Organic and Metarril(r) WP. The efficacy of these M. anisopliae formulations against the tick Rhipicephalus sanguineus s.l. was studied in laboratory under optimum or heat-stress conditions. The products were prepared in water [Tween(r) 80, 0.01 % (v/v)] or pure mineral oil. Conidia from Metarril(r) SP Organic suspended in water presented markedly delayed germination after heating to constant 40 degrees C (for 2, 4, or 6 h) compared to conidia suspended in mineral oil. Metarril(r) SP Organic suspended in oil and exposed to daily cycles of heat-stress (40 degrees C for 4 h and 25 degrees C for 19 h for 5 consecutive days) presented relative germination of conidia ranging from 92.8 to 87.2 % from day 1 to day 5, respectively. Conversely, germination of conidia prepared in water ranged from 79.3 to 39.1 % from day 1 to day 5, respectively. Culturability of Metarril(r) WP decreased from 96 % when conidia were cultured for 30 min prior to heat exposure (40 degrees C for 4 h) to 9 % when conidia were cultured for 8 h. Tick percent control was distinctly higher when engorged females were treated with oil suspensions rather than water suspensions, even when treated ticks were exposed to heat-stress regimen. Oil-based applications protected fungal conidia against heat-stress. Although Metarril(r) is not registered for tick control, it may be useful for controlling R. sanguineus, especially if it is prepared in mineral oil. PMID- 27704217 TI - Henneguya laseeae n. sp. from flathead catfish (Pylodictis olivaris) in the upper Mississippi River. AB - A novel species of Henneguya was isolated from flathead catfish (Pylodictis olivaris) captured in the upper Mississippi River near Lansing (Allamakee County), IA, and La Crosse (La Crosse County), WI. Designated Henneguya laseeae n. sp., this novel species is described using critical morphological features, histology, and 18S ribosomal RNA gene sequence. Ovoid cysts, ranging from 1200 to 1800 MUm in width, tended to be at filament tips or in the distal third, often directly on the filament midline, but occasionally paramedian. Lanceolate-shaped myxospores were consistent with those of the genus Henneguya. The spore body was 16.2 +/- 0.5 MUm (mean +/- standard deviation; range = 15.1-17.0 MUm) in length, 6.0 +/- 0.4 MUm (5.1-6.6 MUm) in width, and 4.7 +/- 0.2 MUm (4.4-4.9 MUm) thick. The two polar capsules at the anterior of the spore body were 5.9 +/- 0.3 MUm (5.3-6.3 MUm) in length and 1.8 +/- 0.1 MUm (1.6-2.1 MUm) in width and contained six to seven turns in the polar filament. The caudal processes tapered to fine points and were 54.3 +/- 2.9 MUm (49.1-61.7 MUm) in length. Total spore length was 70.4 +/- 3.3 MUm (64.5-79.4 MUm). The spores and plasmodium of this species are of similar size and morphology to other species of Henneguya from ictalurid fishes. Additionally, the 18S rRNA gene sequences placed this isolate within a clade populated by Henneguya spp. from North American ictalurids. This is the first reported species of Henneguya from flathead catfish. PMID- 27704218 TI - Direct and indirect parieto-medial temporal pathways for spatial navigation in humans: evidence from resting-state functional connectivity. AB - Anatomical and functional findings in primates suggest the existence of a dedicated parieto-medial temporal pathway for spatial navigation, consisting of both direct and indirect projections from the caudal inferior parietal lobe (cIPL) to the hippocampus and the parahippocampal cortex, with indirect projections relaying through the posterior cingulate and retrosplenial cortex. This neural network is largely unexplored in humans. This study aimed at testing the existence of a parieto-medial temporal pathway for spatial navigation in humans. We explored the cortical connectivity patterns of the parahippocampal place area (PPA), the retrosplenial cortex (RSC), and the hippocampus (HC) using resting-state functional connectivity MRI. Our results demonstrate the existence of connections between the medial temporal lobe structures, i.e., PPA and HC, and the angular gyrus (AG), the human homologue of cIPL, as well as between RSC and AG. These connectivity patterns seem to reflect the direct and the indirect projections found in primates from cIPL to the medial temporal lobe. Such a result deserves feasible considerations to better understand the brain networks underpinning human spatial navigation. PMID- 27704220 TI - A review of the safety of clozapine during pregnancy and lactation. AB - Clozapine is an antipsychotic used in the management of treatment-resistant schizophrenia. However, little is known about clozapine use during pregnancy and lactation, or its impact on the mother, foetus, and infant. This review aims to summarize the available literature on the safety of clozapine use during the perinatal period. EMBASE, PsycINFO, and MEDLINE were searched from their inceptions through June 2016. The review encompasses 21 studies that have examined clozapine use during pregnancy and lactation. The limited available data do not support an increased risk of congenital malformations in foetuses exposed to clozapine during pregnancy, though rates of gestational diabetes are twice as high in pregnant women using clozapine. Clozapine accumulation in foetal serum possibly contributes to increased rates of floppy infant syndrome at delivery, decreased foetal heart rate variability, and seizures in infancy. Clozapine crosses the placenta and also accumulates in breast milk, which may increase the risk of agranulocytosis in infants and may necessitate infant testing. The majority of these data come from case reports and case series, making it unclear if the published risks associated with clozapine are due to mental illness, lifestyle factors, or co-treatment with other psychotropic medications. While the available literature on clozapine use during the perinatal period is very limited, the risks of clozapine use during pregnancy and the postpartum period should be discussed with women and weighed against those associated with other treatments and partially or untreated schizophrenia. PMID- 27704221 TI - Insights into the spontaneity of hydrogen bond formation between formic acid and phthalimide derivatives. AB - We evaluated a group of phthalimide derivatives, which comprise a convenient test set for the study of the multiple factors involved in the energetics of hydrogen bond formation. Accordingly, we carried out quantum chemical calculations on the hydrogen bonded complexes formed between a sample of phthalimide derivatives with formic acid with the intent of identifying the most important electronic and structural factors related to how their strength and spontaneity vary across the series. The geometries of all species considered were fully optimized at DFT B3LYP/6-31++G(d,p), RM1, RM1-DH2, and RM1-D3H4 level, followed by frequency calculations to determine their Gibbs free energies of hydrogen bond formation using Gaussian 2009 and MOPAC 2012. Our results indicate that the phthalimide derivatives that form hydrogen bond complexes most favorably, have in their structures only one C=O group and at least one NH group. On the other hand, the phthalimide derivatives predicted to form hydrogen bonds least favorably, possess in their structures two carbonyl groups, C=O, and no NH group. The ability to donate electrons and simultaneously receive one acidic hydrogen is the most important property related to the spontaneity of hydrogen bond formation. We further chose two cyclic compounds, phthalimide and isoindolin-1-one, in which to study the main changes in molecular, structural and spectroscopic properties as related to the formation of hydrogen bonds. Thus, the greatest ability of the isoindolin-1-one compound in forming hydrogen bonds is evidenced by the larger effect on the structural, vibrational, and chemical shifts properties associated with the O-H group. In summary, the electron-donating ability of the hydrogen bond acceptor emerged as the most important property differentiating the spontaneity of hydrogen bond formation in this group of complexes. PMID- 27704219 TI - Abundant collateralization of temporal lobe projections to the accumbens, bed nucleus of stria terminalis, central amygdala and lateral septum. AB - Behavioral flexibility is subserved in part by outputs from the cerebral cortex to telencephalic subcortical structures. In our earlier evaluation of the organization of the cortical-subcortical output system (Reynolds and Zahm, J Neurosci 25:11757-11767, 2005), retrograde double-labeling was evaluated in the prefrontal cortex following tracer injections into pairs of the following subcortical telencephalic structures: caudate-putamen, core and shell of the accumbens (Acb), bed nucleus of stria terminalis (BST) and central nucleus of the amygdala (CeA). The present study was done to assess patterns of retrograde labeling in the temporal lobe after similar paired tracer injections into most of the same telencephalic structures plus the lateral septum (LS). In contrast to the modest double-labeling observed in the prefrontal cortex in the previous study, up to 60-80 % of neurons in the basal and accessory basal amygdaloid nuclei and amygdalopiriform transition area exhibited double-labeling in the present study. The most abundant double-labeling was generated by paired injections into structures affiliated with the extended amygdala, including the CeA, BST and Acb shell. Injections pairing the Acb core with the BST or CeA produced significantly fewer double-labeled neurons. The ventral subiculum exhibited modest amounts of double-labeling associated with paired injections into the Acb, BST, CeA and LS. The results raise the issue of how an extraordinarily collateralized output from the temporal lobe may contribute to behavioral flexibility. PMID- 27704224 TI - Genomic Selection Using Extreme Phenotypes and Pre-Selection of SNPs in Large Yellow Croaker (Larimichthys crocea). AB - Genomic selection (GS) is an effective method to improve predictive accuracies of genetic values. However, high cost in genotyping will limit the application of this technology in some species. Therefore, it is necessary to find some methods to reduce the genotyping costs in genomic selection. Large yellow croaker is one of the most commercially important marine fish species in southeast China and Eastern Asia. In this study, genotyping-by-sequencing was used to construct the libraries for the NGS sequencing and find 29,748 SNPs in the genome. Two traits, eviscerated weight (EW) and the ratio between eviscerated weight and whole body weight (REW), were chosen to study. Two strategies to reduce the costs were proposed as follows: selecting extreme phenotypes (EP) for genotyping in reference population or pre-selecting SNPs to construct low-density marker panels in candidates. Three methods of pre-selection of SNPs, i.e., pre-selecting SNPs by absolute effects (SE), by single marker analysis (SMA), and by fixed intervals of sequence number (EL), were studied. The results showed that using EP was a feasible method to save the genotyping costs in reference population. Heritability did not seem to have obvious influences on the predictive abilities estimated by EP. Using SMA was the most feasible method to save the genotyping costs in candidates. In addition, the combination of EP and SMA in genomic selection also showed good results, especially for trait of REW. We also described how to apply the new methods in genomic selection and compared the genotyping costs before and after using the new methods. Our study may not only offer a reference for aquatic genomic breeding but also offer a reference for genomic prediction in other species including livestock and plants, etc. PMID- 27704223 TI - Gene Co-Expression Network Analysis Reveals the Correlation Patterns Among Genes in Euryhaline Adaptation of Crassostrea gigas. AB - The Pacific oyster Crassostrea gigas is a dominant aquaculture species in many intertidal zones throughout the Pacific and Atlantic Oceans and can tolerate a wide range of salinity. Studying the gene expression profiles of oyster gills had found differentially expressed genes (DEGs) involved in salinity tolerance. A systematic study of cellular response to salinity stress may provide insights into the mechanism of acquired salinity tolerance. Here, weighted gene co expression network analysis (WGCNA) was carried out using RNA-seq data from gill transcriptome in response to different salinity. A total of 25,463 genes were parsed into 22 gene modules, of which 5 gene modules were identified as salinity related modules. Brown module was the only one significantly correlated with salinity and free amino acids (FAAs) contents, which was associated with cellular metabolism, biosynthesis of amino acids, oxidation reduction, electron transport, nitrogen compound metabolism, and others. The enriched pathways in brown module were mainly about FAAs metabolism. The other four modules were significantly correlated with certain FAAs, and were over-represented in certain salinity. These results indicated that C. gigas triggered different FAAs in different salinity stress. This study represents the first RNA-seq gene network analysis in oysters responding to different salinity stresses. These results provide a systems-level framework to help understand the complexity of cellular process in response to osmotic stress and show the function and regulated genes of different FAAs at the molecular level. PMID- 27704222 TI - Distinct differences in metal ion specificity of RNA and DNA G-quadruplexes. AB - RNA G-quadruplexes, as their well-studied DNA analogs, require the presence of cations to fold and remain stable. This is the first comprehensive study on the interaction of RNA quadruplexes with metal ions. We investigated the formation and stability of two highly conserved and biologically relevant RNA quadruplex forming sequences (24nt-TERRA and 18nt-NRAS) in the presence of several monovalent and divalent metal ions, namely Li+, Na+, K+, Rb+, Cs+, NH4+, Mg2+, Ca2+, Sr2+, and Ba2+. Circular dichroism was used to probe the influence of these metal ions on the folded fraction of the parallel G-quadruplexes, and UV thermal melting experiments allowed to assess the relative stability of the structures in each cationic condition. Our results show that the RNA quadruplexes are more stable than their DNA counterparts under the same buffer conditions. We have observed that the addition of mainly Na+, K+, Rb+, NH4+, as well as Sr2+ and Ba2+ in water, shifts the equilibrium to the folded quadruplex form, whereby the NRAS sequence responds stronger than TERRA. However, only K+ and Sr2+ lead to a significant increase in the stability of the folded structures, which is consistent with their coordination to the O6 atoms from the G-quartet guanosines. Compared to the respective DNA motives, dNRAS and htelo, the RNA sequences are not stabilized by Na+ ions. Finally, the difference in response between NRAS and TERRA, as well as to the corresponding DNA sequences with respect to different metal ions, could potentially be exploited for selective targeting purposes. PMID- 27704225 TI - Updated evidence on endoscopic resection of early gastric cancer from Japan. AB - BACKGROUND: Endoscopic resection for early gastric cancer (EGC) plays a central role in the treatment of EGC in Japan. However, there is still room for improvement, and it is necessary to summarize the recently obtained knowledge from Japan for further improvement. METHODS: We conducted a PubMed search to select relevant articles in the 5 years until September 18, 2016, using the keywords "gastric cancer" and "endoscopic treatment," "endoscopic submucosal dissection," "endoscopic mucosal resection," or "polypectomy" and filtering article types as "clinical study" or "clinical trial." RESULTS: Among the 329 articles selected automatically from the keywords "polypectomy" (1 article), "endoscopic mucosal resection" (29 articles), "endoscopic submucosal dissection" (77 articles), and "endoscopic treatment" (222 articles) in combination with "gastric cancer," 32 relevant articles from Japanese investigators were chosen. Seven articles were categorized into "equipment," 4 into "preparation and sedation," 17 into "complications and their prevention," and 4 into "therapeutic outcomes." Among them, CO2 insufflation, propofol sedation, and how to prevent post-endoscopic submucosal dissection (ESD) ulcer bleeding and achieve post-ESD ulcer healing were intensively investigated. Long-term outcomes of endoscopic mucosal resection and ESD were also reported as favorable outcomes. CONCLUSIONS: Endoscopic resection for EGC is still developing toward an ideal form, pursuing a more reliable, safer, and faster minimally invasive treatment.

PMID- 27704226 TI - Impact of neoadjuvant therapy on eligibility for and frequency of breast conservation in stage II-III HER2-positive breast cancer: surgical results of CALGB 40601 (Alliance). AB - OBJECTIVE: It had been previously shown that patients who receive neoadjuvant systemic therapy (NST) are more likely to undergo breast-conserving therapy (BCT) than those who have primary surgery. However, the frequency with which patients who are not BCT-eligible prior to NST convert to BCT-eligible with treatment is unknown. To document this conversion rate in a subset of patients expected to have a high clinical response rate to NST, we studied surgical assessment and management of patients enrolled on a randomized neoadjuvant trial for stage II III HER2-positive breast cancer (HER2 + BC)(CALGB 40601). METHODS: The treating surgeon assessed BCT candidacy based on clinico-radiographic criteria both before and after NST. Definitive breast surgical management was at surgeon and patient discretion. We sought to determine (1) the conversion rate from BCT-ineligible to BCT-eligible (2) the percentage of BCT-eligible patients who chose breast conservation, and (3) the rate of successful BCT. We also evaluated surgeon determined factors for BCT-ineligibility and the correlation between BCT eligibility and pathologic complete response (pCR). RESULTS: Of 292 patients with pre- and post-NST surgical assessments, 59 % were non-BCT candidates at baseline. Of the 43 % of these patients who converted with NST, 67 % opted for BCT, with an 80 % success rate. NST increased the BCT-eligible rate from 41 to 64 %. Common factors cited for BCT-ineligibility prior to NST including tumor size (56 %) and probable poor cosmetic outcome (26 %) were reduced by 67 and 75 %, respectively, with treatment, while multicentricity, the second most common factor (33 %), fell by only 16 %. Since 23 % of the BCT-eligible patients chose mastectomy, BCT was the final surgical procedure in just 40 % of the patients. Patients considered BCT-eligible both at baseline and after NST had a pCR rate of 55 %, while patients who were BCT-ineligible prior to NST had the same pCR rate (44 %) whether they converted to BCT-eligible or not. CONCLUSIONS: Many patients with HER2 + BC deemed ineligible for BCT at baseline can be converted to BCT-eligible with NST; excluding patients with multicentric disease substantially increases that percentage. In converted patients who opt for BCT, the success rate is similar to that of patients considered BCT-eligible at baseline. Whether a BCT ineligible patient converts to BCT eligibility or not does not appear to affect the likelihood of achieving a pCR. Despite the efficacy of NST in this patient cohort, only 40 % of patients had successful BCT; further research into why BCT eligible patients often opt for mastectomy is needed.

PMID- 27704229 TI - Automatic construction of subject-specific human airway geometry including trifurcations based on a CT-segmented airway skeleton and surface. AB - We propose a method to construct three-dimensional airway geometric models based on airway skeletons, or centerlines (CLs). Given a CT-segmented airway skeleton and surface, the proposed CL-based method automatically constructs subject specific models that contain anatomical information regarding branches, include bifurcations and trifurcations, and extend from the trachea to terminal bronchioles. The resulting model can be anatomically realistic with the assistance of an image-based surface; alternatively a model with an idealized skeleton and/or branch diameters is also possible. This method systematically identifies and classifies trifurcations to successfully construct the models, which also provides the number and type of trifurcations for the analysis of the airways from an anatomical point of view. We applied this method to 16 normal and 16 severe asthmatic subjects using their computed tomography images. The average distance between the surface of the model and the image-based surface was 11 % of the average voxel size of the image. The four most frequent locations of trifurcations were the left upper division bronchus, left lower lobar bronchus, right upper lobar bronchus, and right intermediate bronchus. The proposed method automatically constructed accurate subject-specific three-dimensional airway geometric models that contain anatomical information regarding branches using airway skeleton, diameters, and image-based surface geometry. The proposed method can construct (i) geometry automatically for population-based studies, (ii) trifurcations to retain the original airway topology, (iii) geometry that can be used for automatic generation of computational fluid dynamics meshes, and (iv) geometry based only on a skeleton and diameters for idealized branches.

PMID- 27704230 TI - Smoking cessation and long-term weight gain in the Framingham Heart Study: an application of the parametric g-formula for a continuous outcome. AB - Weight gain after smoking cessation can lessen the health benefits of, and reduce the incentives for, quitting smoking. Randomized clinical trials of smoking cessation have estimated this weight gain only over short periods of follow-up. We provide an estimate of long-term post-cessation weight gain in the Framingham Heart Study, a prospective observational study. We identified 2001 smokers free of diabetes, cancer, and cardiovascular disease in 1952. Using the parametric g formula we estimated mean weight in 1972 if all smokers had quit at baseline versus if all had continued smoking. Our estimates were adjusted for demographic, socio-economic, and clinical factors at baseline and during follow-up. The estimated mean weight (95 % CI) at 20 years if all smokers had quit smoking was 75.2 kg (73.5, 76.6), compared with 70.2 kg (68.7, 71.8) if they had smoked 20 cigarettes/day and 73.4 kg (71.9, 74.6) if they had smoked 5 cigarettes/day (i.e., an estimated mean weight gain of 5.1 kg (3.1, 6.6) and 1.8 kg (0.8, 2.8), respectively). Smokers who were overweight or obese at baseline had a greater post-cessation weight gain on average. Our estimates suggest that smoking cessation can result in increases in body weight over 20 years. While the benefits of smoking cessation outweigh the risks due to post-cessation weight gain, our results highlight the need for long-term weight management interventions in combination with smoking cessation.

AB - Absorption and fluorescence studies on novel Schiff bases (E)-4-(4-(4-nitro benzylideneamino)benzyl)oxazolidin-2-one (NBOA) and (E)-4-(4-(4-chlorobenzylidene amino)benzyl)oxazolidin-2-one (CBOA) were recorded in a series of twelve solvents upon increasing polarity at room temperature. Large Stokes shift indicates bathochromic fluorescence band for both the molecules. The photoluminescence properties of Schiff bases containing electron withdrawing and donating substituents were analyzed. Intramolecular charge transfer behavior can be studied based on the influence of different substituents in Schiff bases. Changes in position and intensity of absorption and fluorescence spectra are responsible for the stabilization of singlet excited-states of Schiff base molecules with different substituents, in polar solvents. This is attributed to the Intramolecular charge transfer (ICT) mechanism. In case of electron donating ( Cl) substituent, ICT contributes largely to positive solvatochromism when compared to electron withdrawing (-NO2) substituent. Ground-state and singlet excited-state dipole moments of NBOA and CBOA were calculated experimentally using solvent polarity function approaches given by Lippert-Mataga, Bakhshiev, Kawskii-Chamma-Viallet and Reichardt. Due to considerable pi- electron density redistribution, singlet excited-state dipole moment was found to be greater than ground-state dipole moment. Ground-state dipole moment value which was determined by quantum chemical method was used to estimate excited-state dipole moment using solvatochromic correlations. Kamlet-Abboud-Taft and Catalan multiple linear regression approaches were used to study non-specific solute-solvent interaction and hydrogen bonding interactions in detail. Optimized geometry and HOMO-LUMO energies of NBOA and CBOA have been determined by DFT and TD-DFT/PCM (B3LYP/6 311G (d, p)). Mulliken charges and molecular electrostatic potential have also been evaluated from DFT calculations. PMID- 27704232 TI - Activating glutamate decarboxylase activity by removing the autoinhibitory domain leads to hyper gamma-aminobutyric acid (GABA) accumulation in tomato fruit. AB - KEY MESSAGE: The C-terminal extension region of SlGAD3 is likely involved in autoinhibition, and removing this domain increases GABA levels in tomato fruits. gamma-Aminobutyric acid (GABA) is a ubiquitous non-protein amino acid with several health-promoting benefits. In many plants including tomato, GABA is synthesized via decarboxylation of glutamate in a reaction catalyzed by glutamate decarboxylase (GAD), which generally contains a C-terminal autoinhibitory domain. We previously generated transgenic tomato plants in which tomato GAD3 (SlGAD3) was expressed using the 35S promoter/NOS terminator expression cassette (35S SlGAD3-NOS), yielding a four- to fivefold increase in GABA levels in red-ripe fruits compared to the control. In this study, to further increase GABA accumulation in tomato fruits, we expressed SlGAD3 with (SlGAD3 OX ) or without (SlGAD3DeltaC OX ) a putative autoinhibitory domain in tomato using the fruit ripening-specific E8 promoter and the Arabidopsis heat shock protein 18.2 (HSP) terminator. Although the GABA levels in SlGAD3 OX fruits were equivalent to those in 35S-SlGAD3-NOS fruits, GABA levels in SlGAD3DeltaC OX fruits increased by 11- to 18-fold compared to control plants, indicating that removing the autoinhibitory domain increases GABA biosynthesis activity. Furthermore, the increased GABA levels were accompanied by a drastic reduction in glutamate and aspartate levels, indicating that enhanced GABA biosynthesis affects amino acid metabolism in ripe-fruits. Moreover, SlGAD3DeltaC OX fruits exhibited an orange ripe phenotype, which was associated with reduced levels of both carotenoid and mRNA transcripts of ethylene-responsive carotenogenic genes, suggesting that over activation of GAD influences ethylene sensitivity. Our strategy utilizing the E8 promoter and HSP terminator expression cassette, together with SlGAD3 C-terminal deletion, would facilitate the production of tomato fruits with increased GABA levels.

AB - Photophysical properties of a multidentate tripodal ligand, 5,5'-(2-(((8 hydroxyquinolin-5-yl) methylamino)methyl)-2-methylpropane-1,3-diyl) bis (azanediyl)bis (methylene)diquinolin-8-ol, (TAME5OX), with La3+ and Er3+ ions have been examined for photonics applications. The change in behavior in electronic spectra of these complexes reveals the use of TAME5OX as a sensitive optical pH based sensor to detect Ln3+ ions whereas indication of strong green fluorescence allows simultaneous sensing within the visible region in competitive medium. The intense fluorescence intermittently gets quenched under acidic and basic conditions due to photoinduced intramolecular electron transfer from the excited 8-hydroxyquinoline (8-HQ) moiety to the metal ion. This renders these compounds the OFF-ON-OFF type of pH-dependent fluorescent sensor. The thermodynamic stability and coordination behaviour of the chelator with the said lanthanide ions have also been probed by potentiometric, UV - visible and fluorescence spectrophotometric method. TAME5OX forms protonated complex [Ln (H4L)]4+ below pH ~4.0 which sequentially deprotonates through one proton process with increase of pH. The stability constants of neutral complexes have been determined to be in the range log beta110 = 32-34 and pLn in the range of 14-20, indicating TAME5OX is a good synthetic lanthanide chelator. Theoretical spectra were also calculated by ZINDO/s methodology at single excitations (CIS) level on PM7 as sparkle energy-minimized geometries.

AB - Common variable immunodeficiency is a rare disorder of immunity associated with a myriad of clinical manifestations including recurrent infections, autoimmunity, and malignancy. Though rare, neurologic complications have been described in a small number of case reports and case series of CVID patients. In this article, we present a patient with CVID who suffered significant neurologic morbidity and categorize the reported range of neurologic complications associated with CVID. Our case highlights the complex nature of neurologic manifestations in CVID patients, and our review of the current database suggests that infection and inflammatory neurologic disorders are the cause of most neurologic presentations. PMID- 27704237 TI - Rise of the Machines: A Critical Review on the Behavioural Effects of Automating Traditional Gambling Games. AB - Automated gambling products are now a common feature on many casino floors. Despite their increasing prevalence, little research has considered the impact of converting games traditionally free from technological enhancements to automated versions. This review seeks to illustrate how automation is likely to change the way people engage and experience traditional games based around five prominent modifications: visual and auditory enhancements; illusions of control; cognitive complexity; expedited play; and social customisation. Otherwise known as the "VICES" framework. The inclusion of rich graphics, event-dependent sound and game play information such as statistics, history, betting options and strategic betting are likely to prolong and entice gambling while encouraging more intense betting. Changes to the social environment due to the asocial nature of automated products is also likely to significantly change the gambling experience. Given the increasing prevalence of these products in the marketplace, it is important to consider the implications of converting traditional products to automated form as technological enhancements have the potential to allow for faster, more intense betting. More research is needed to determine the full impact of automation on player behaviours in order to understand the potential risks associated with technological enhancements to traditional games. PMID- 27704238 TI - MY MOTHER, MY STORY. AB - This piece returns to the writer's memoir essays about her mother's chronic lung disease to examine the relationship between the act of caregiving and the act of writing. In arguing for important differences between the clinical, healing imperatives of narrative medicine and the primacy for the writer of self reflection, personal need and career, the essay demonstrates how writing remains in many ways at odds with the obligations and the hopes of caregiving. At the same time, the essay argues that writing her mother's stories of illness holds the potential for both honor and mutuality-and can, in fact, constitute a form of caregiving. PMID- 27704239 TI - Objective Bayesian Comparison of Constrained Analysis of Variance Models. AB - In the social sciences we are often interested in comparing models specified by parametric equality or inequality constraints. For instance, when examining three group means [Formula: see text] through an analysis of variance (ANOVA), a model may specify that [Formula: see text], while another one may state that [Formula: see text], and finally a third model may instead suggest that all means are unrestricted. This is a challenging problem, because it involves a combination of nonnested models, as well as nested models having the same dimension. We adopt an objective Bayesian approach, requiring no prior specification from the user, and derive the posterior probability of each model under consideration. Our method is based on the intrinsic prior methodology, suitably modified to accommodate equality and inequality constraints. Focussing on normal ANOVA models, a comparative assessment is carried out through simulation studies. We also present an application to real data collected in a psychological experiment. PMID- 27704241 TI - Consistent individual differences in seed disperser quality in a seed-eating fish. AB - Animal-mediated seed dispersal (zoochory) is considered to be an important mechanism regulating biological processes at larger spatial scales. To date, intra-specific variation in seed disperser quality within seed-dispersing animals has not been studied. Here, I employed seed feeding trials to quantify individual differences in disperser quality within the common carp (Cyprinus carpio) using seeds of two aquatic plants: unbranched bur-reed (Sparganium emersum, Sparganiaceae) and arrowhead (Sagittaria sagittifolia, Alismataceae). I found substantial variation among carp individuals in their propensity to ingest seeds and their ability to digest them, resulting in up to 31-fold differences in the probability of seed dispersal. In addition, there were significant differences in the time that seeds are retained in their digestive systems, generating a twofold difference in the maximum distance over which they can potentially disperse seeds. I propose that seed-eating animal species consist of individuals that display continuous variation in disperser quality, with at one end of the continuum individuals that are likely to eat seeds, pass them unharmed through their digestive tract and transport them over large distances to new locations (i.e. high-quality seed dispersers) and at the other end individuals that rarely eat seeds, destroy most of the ones they ingest and transport the few surviving seeds over relatively short distances (low-quality seed dispersers). Although individual differences in seed dispersal quality could be the result of a variety of factors, these results underline the ecological and evolutionary potential of such variation for both plants and animals. PMID- 27704242 TI - Training residents in laparoscopic colorectal surgery: is supervised surgery safe? AB - BACKGROUND: Colorectal resections are increasingly performed laparoscopically, and training in laparoscopic resections in the Netherlands has shifted from a post-residency fellowship to training in residency. The question remains if this supervised surgery affects short-term patient outcome. METHODS: Between January 2010 and July 2014, 523 consecutive patients, who underwent laparoscopic colorectal resection, were selected from a prospective single-center database. All data were obtained from the maintained database and retrospectively analyzed. We compared the short-term outcome of patients who underwent laparoscopic colorectal surgery by a supervised fifth- or sixth-year resident compared to patients who underwent laparoscopic colorectal surgery performed by a dedicated colorectal surgeon. Statistical analysis was performed using the Chi-square test for categorical variables and the t test for continuous variables. RESULTS: Almost 40 % of operations were performed by a resident with an even distribution in type of resection, except for the abdominal-perineal resection (residents vs. surgeon 3.57 vs. 8.26 %, p = 0.04) and the total number of patients who underwent preoperative chemoradiation (resident vs. surgeon 6.66 vs. 20.65 %, p = 0.04). No difference was found in operative time or per-operative blood loss. A higher conversion rate was found when surgery was performed by a supervised resident (residents vs. surgeon 17.34 vs. 9.17 %, p = 0.01), which could be attributed to case selection and one single year. No differences in major complications, oncological outcome and construction of a stoma were found. In the case of minor complications, a significantly increased percentage of bladder retention was found in the surgeon group (residents vs. surgeon 1 vs. 4.6 %, p = 0.03). CONCLUSIONS: In this study, we found that patient safety and short-term outcome are not adversely affected when laparoscopic colorectal surgery is performed by a supervised fifth- or sixth-year resident. PMID- 27704243 TI - Optimizing a living kidney donation program: transition to hand-assisted retroperitoneoscopic living donor nephrectomy and introduction of a passive polarizing three-dimensional display system. AB - BACKGROUND: Optimizing a living kidney donation program is important to guarantee a high grade of acceptance among potential donors. Hand-assisted retroperitoneoscopic donor nephrectomy (HARP) is an alternative to the open anterior approach (AA) technique. Problems associated to the learning curve could hinder a transition. 3D display technique seems to ease minimally invasive surgery. Aim of this study was to evaluate the learning curve during the transition from AA to HARP and the influence of the 3D display system on the established technique. METHODS: Observational study (n = 207) during transition to HARP and introduction of 3D display technique. RESULTS: Operation time (OT), warm ischemia time (WIT) and blood loss (BL) of HARP decreased during transition. Pairwise group comparison for OT showed a significant learning effect for the first 30 out of 50 HARPs without influence on graft function. Between AA and HARP no significant difference in OT (133 +/- 24 vs. 127 +/- 19 min, p = 0.25) but for WIT (23 +/- 28 vs. 126 +/- 40 s, p < 0.005) and BL (328 +/- 207 vs. 54 +/- 35 ml, p < 0.005) was seen. There was neither a significant difference in donors' nor recipients' eGFR. OT (98 +/- 16 vs. 106 +/- 19 min, p = 0.036) and WIT (97 +/- 37 vs. 120 +/- 57 s, p = 0.023) were significantly shorter for the 3D technique compared to 2D. CONCLUSION: A transition to HARP is possible without additional risk for the donor or loss of quality for the recipient. The learning curve for HARP is steep and short. The introduction of 3D display technique after transition facilitates the surgical preparation and could further help to optimize HARP. PMID- 27704244 TI - Laparoscopic surgery in patients with colon cancer: a population-based analysis. AB - BACKGROUND: The long-term outcomes after laparoscopic surgery for colon cancer remain debatable, as randomized trials have reported similar outcomes for open and laparoscopic surgery but population-based data are scarce. Thus, it is unclear whether, outside of clinical trials, laparoscopic surgery that is performed as a standard clinical treatment has detrimental effects on patients' long-term survival. METHODS: This study examined a unified database of 30 German regional cancer registries for patients with colorectal cancer who were diagnosed between 2003 and 2011. Among 216,682 patients with colorectal carcinoma, we identified 37,068 patients with Union for International Cancer Control stage I III colon carcinoma (>12 cm from the anal verge), including 3825 patients (10.38 %) who underwent laparoscopic surgery. Multivariate Cox regression analyses were also used to evaluate factors that influenced the likelihood of a patient undergoing laparoscopic surgery. Kaplan-Meier analysis with the log-rank test was used to analyse differences in short- and long-term survival outcomes after open or laparoscopic surgery. RESULTS: Younger age, lower T-stage, and left-sided surgery were independent predictors of the patient undergoing laparoscopic surgery (all, p < 0001). The 30-day mortality rate was significantly lower for patients who underwent laparoscopic surgery for left-sided tumours (odds ratio [OR] 0.49; 95 % confidence interval [CI] 0.33-0.77). Compared to open surgery, laparoscopic surgery was a significant and independent predictor of prolonged long-term survival for right- and left-sided surgeries (right-side, OR 0.67; 95 % CI 0.56-0.82; left-sided, OR 0.70; 95 % CI 0.62-0.78). CONCLUSION: Our results indicate that laparoscopic surgery provides favourable outcomes even when used outside controlled trials and should be considered as a standard treatment for patients with colon cancer. PMID- 27704245 TI - Pediatric neurofibromatosis type 2: clinical and molecular presentation, management of vestibular schwannomas, and hearing rehabilitation. AB - OBJECTIVE: This study aims to describe the clinical and molecular presentation of pediatric neurofibromatosis type 2 (NF2) and the subsequent management of vestibular schwannomas (VS) and hearing rehabilitation. METHODS: This is a single center retrospective study of neurofibromatosis type 2 diagnosed before the age of 18 years old from 1997. Natural history of vestibular schwannomas and surgical outcomes were evaluated using volumetric MRI, hearing, and facial nerve assessment. Patients included in chemotherapy protocols were excluded. RESULTS: From a database of 80 patients followed up for NF2 on a regular basis, 25 patients were eligible (11 sporadic cases, 14 inherited in five families). The mean age at diagnosis was 11.6 years old. The average clinical follow-up was 6.5 years. NF2 mutation was identified in 81 % of the probands. The average growth rate based on the maximum linear diameter (DGR) was 1.68 mm/year (n = 33, average follow-up 4.22 years) and 545 mm3/year in volumetric assessment (VGR) for VS larger than 1 cm (n = 21, average follow-up 3.4 years). In unoperated ears, hearing was stable in about 50 % of ears. The mean change in dB HL was 9.5 dB/year for pure-tone average and 3.5 for speech-recognition threshold (n = 34, 5.5 years 1-12). Eight children required removal through a translabyrinthine approach (mean follow-up was 4.5 years), six patients were operated on for hearing preservation (mean postoperative follow-up 4.3 years). Six patients were eligible for hearing rehabilitation with cochlear implantation (I), and five received placement of an auditory brainstem implant. CONCLUSION: Early diagnosis and treatment of small growing VS should be carefully discussed considering familial history and possible rehabilitation with a CI. PMID- 27704246 TI - Tadpole-shaped lateralized parietal atretic cephalocele associated with an ipsilateral lacrimal gland fistula and schizencephalic clefts. AB - BACKGROUND: Parietal atretic cephalocele (AC) and its associated intracranial venous anomalies, such as vertical embryonic positioning of the straight sinus (VEP of SS), have, in previous reports, been exclusively restricted to the midline. CLINICAL PRESENTATION: We report a patient with lateralized parietal AC on the right side. The AC was in the shape of a tadpole, with a large head and a long tail, extending to the proximity of the right external canthus, where a lacrimal gland fistula was observed. The superior sagittal sinus and VEP of SS were also displaced to the right side, although the sagittal suture was located at the midline. Schizencephalic clefts in the right posterior cortex were also observed. CONCLUSION: The parietal AC, which was initially located in the midline, could conceivably have been displaced to the right side by other developmental processes. However, the relationship between lateralized AC and associated multiple anomalies on the ipsilateral side is difficult to explain monogenetically. Our case study indicates that AC might have a broader spectrum of clinical symptoms than was once thought to be the case. PMID- 27704247 TI - Childhood acute basilar artery thrombosis successfully treated with mechanical thrombectomy using stent retrievers: case report and review of the literature. AB - INTRODUCTION: Acute basilar artery occlusion (ABAO) is an infrequent but potentially fatal cause of strokes in both adults and children, and it is usually due to vertebral artery dissection (VAD). VAD has been found to be usually a consequence of traumatic vertebral artery injury. ABAO usually presents with symptoms of acute ischemic stroke (AIS) of the posterior circulation or transient ischemic attack (TIA). It may lead to death or long-term disability if not promptly recanalized. Basilar artery recanalization in children can be achieved safely and with excellent clinical outcome using endovascular thrombectomy with the new generation self-expanding and retrievable stents. CLINICAL PRESENTATION: We report the case of a 23-month old baby that came to the emergency room of our hospital for progressive impairment of consciousness associated with widespread stiffness and plaintive cry, appeared after accidental fall from stroller. An emergency brain CT scan was obtained showing multiple infarction lesions in the brainstem and left cerebellum suggestive of acute stroke in posterior circulation territories. An MR scan with angiography and diffusion-weighted sequences confirmed the multiple infarction lesions and demonstrated poor representation of the flow signal at the V3 segment of the left vertebral artery and absent representation of the flow signal at the distal segment of the basilar artery suggestive of acute thrombotic occlusion. The patient was immediately referred to interventional neuroradiology unit, and digital subtraction angiography showed complete basilar artery occlusion and left vertebral artery dissection at extracranial V2-V3 segment. The patient underwent intra-arterial thrombectomy using stent retrievers and occlusion of the V2-V3 segment of the left vertebral artery. The patient survived and long-term outcome was excellent. CONCLUSIONS: To our knowledge, only nine cases of ABAO in children treated with intra-arterial thrombectomy have been previously reported in the literature. In only three cases, the Solitaire stent was applied. Our case is the first case of basilar artery occlusion treated with Solitaire stent, in a child under 24 months. The reports that are available so far indicate that basilar artery recanalization in children can be achieved safely and with excellent clinical outcome using endovascular thrombectomy with the new generation self-expanding and retrievable stents. PMID- 27704248 TI - Effect of postoperative major complications on prognosis after pancreatectomy for pancreatic cancer: a retrospective review. AB - PURPOSE: To investigate the impact of postoperative complications on survival after curative resection for pancreatic cancer. METHODS: We reviewed retrospectively the medical records of 122 patients who underwent curative R0 resection for pancreatic cancer. Major complications included pancreatic fistula and hemorrhage of grade B or C according to the International Study Group of Pancreatic Fistula or Surgery criteria, and other complications of grade >=III according to the Clavien-Dindo classification. RESULTS: Thirty-eight patients (31 %) suffered major postoperative complications and 40 patients (33 %) suffered minor complications only. Univariate survival analysis showed that patients with major complications had a significantly worse prognosis than those without major complications, with regard to recurrence-free survival (RFS) (P < 0.01) and overall survival (OS) (P < 0.01), whereas minor complications did not affect survival. Major complications significantly inhibited or delayed adjuvant chemotherapy. Multivariate survival analysis showed that the absence of postoperative major complications was an independent favorable factor for RFS (hazard ratio 0.48; 95 % confidence interval: 0.28-0.85) and OS (hazard ratio 0.47; 95 % confidence interval 0.27-0.81). CONCLUSIONS: Postoperative major complications after pancreatectomy for pancreatic cancer affect the prognosis. PMID- 27704249 TI - LRP5/canonical Wnt signalling and healing of ischemic myocardium. AB - LRP5 (low-density lipoprotein receptor-related protein 5) activates canonical Wnt signalling. LRP5 plays multiple roles including regulation of lipoprotein and cholesterol homeostasis as well as innate immunity cell function. However, it is not known whether LRP5 has a role in the myocardium. The aim of this study was to investigate LRP5 and Wnt signalling in myocardial remodelling after acute myocardial infarction (MI). Wnt protein levels were determined in a hypercholesterolemic porcine model of MI, in Lrp5 -/- C57Bl6 mice, in cultured cardiomyocytes and in human explanted hearts with previous MI episodes. 21 days post-MI, there was upregulation of LRP5 in the ischemic myocardium of hypercholesterolemic pigs as well as an upregulated expression of proteins of the Wnt pathway. We demonstrate via overexpression and silencing experiments that LRP5 induces Wnt pathway activation in isolated cardiomyocytes. Hypoxia and lipid loading induced the expression of Wnt proteins, whereas this effect is blocked in LRP5-silenced cardiomyocytes. To characterize the function of the LRP5-Wnt axis upregulation in the heart, we induced MI in wild-type and Lrp5 -/- mice. Lrp5 -/- mice had significantly larger infarcts than Wt mice, indicating a protective role of LRP5 in injured myocardium. The LRP5 upregulation in post-MI hearts seen in pigs and mice was also evident in human hearts as dyslipidemic patients with previous episodes of ischemia have higher expression of LRP5 and Wnt-signalling genes than non-ischemic dilated hearts. We demonstrate an upregulation of LRP5 and the Wnt signalling pathway that it is a prosurvival healing response of cardiomyocytes upon injury. PMID- 27704250 TI - Regulatory T Cells in SLE: Biology and Use in Treatment. AB - T regulatory cells (Tregs) represent a phenotypically and functionally heterogeneous group of lymphocytes that exert immunosuppressive activities on effector immune responses. Tregs play a key role in maintaining immune tolerance and homeostasis through diverse mechanisms which involve interactions with components of both the innate and adaptive immune systems. As in many autoimmune diseases, Tregs have been proposed to play a relevant role in the pathogenesis of systemic lupus erythematosus (SLE), an autoimmune disease characterized by a progressive breakdown of tolerance to self-antigens and the presence of concomitant hyperactive immune responses. Here, we review how Tregs dysfunction in SLE has been manipulated experimentally and preclinically in the attempt to restore, at last in part, the immune disturbances in the disease. PMID- 27704251 TI - Trauma-Informed HIV Prevention and Treatment. AB - The high prevalence of trauma and its negative impact on health and health promoting behaviors underscore the need for multi-level interventions to address trauma and its associated sequelae to improve physical and mental well-being in both HIV-infected and HIV-uninfected populations. Growing global awareness of the intersection of trauma and HIV has resulted in development and testing of interventions to address trauma in the context of HIV treatment and HIV prevention in the USA and globally. Despite increasing recognition of the widespread nature of trauma and the importance of trauma to HIV transmission around the globe, several gaps remain. Through a survey of the literature, we identified eight studies (published in the past 5 years) describing interventions to address the effects of trauma on HIV-related outcomes. In particular, this study focused on the levels of intervention, populations the interventions were designed to benefit, and types of trauma addressed in the interventions in the context of both HIV prevention and treatment. Remarkably absent from the HIV prevention, interventions reviewed were interventions designed to address violence experienced by men or transgender individuals, in the USA or globally. Given the pervasive nature of trauma experienced generally, but especially among individuals at heightened risk for HIV, future HIV prevention interventions universally should consider becoming trauma-informed. Widespread acknowledgement of the pervasive impact of gender-based violence on HIV outcomes among women has led to multiple calls for trauma-informed care (TIC) approaches to improve the effectiveness of HIV services for HIV-infected women. TIC approaches may be relevant for and should also be tested among men and all groups with high co occurring epidemics of HIV and trauma (e.g., men who have sex with men (MSM), transgendered populations, injection drug users, sex workers), regardless of type of trauma experience.

AB - Chronic kidney disease (CKD) is associated with an increased risk of cardiovascular mortality, infections, and impaired cognitive function. It is characterized by excessively increased levels of the phosphaturic hormone fibroblast growth factor 23 (FGF23) and a deficiency of its co-receptor Klotho. Despite the important physiological effect of FGF23 in maintaining phosphate homeostasis, there is increasing evidence that higher FGF23 levels are a risk factor for mortality and cardiovascular disease. FGF23 directly induces left ventricular hypertrophy via activation of the FGF receptor 4/calcineurin/nuclear factor of activated T cells signaling pathway. By contrast, the impact of FGF23 on endothelial function and the development of atherosclerosis are poorly understood. The results of recent experimental studies indicate that FGF23 directly impacts on hippocampal neurons and may thereby impair learning and memory function in CKD patients. Finally, it has been shown that FGF23 interferes with the immune system by directly acting on polymorphonuclear leukocytes and macrophages. In this review, we discuss recent data from clinical and experimental studies on the extrarenal effects of FGF23 with respect to the cardiovascular, central nervous, and immune systems.

PMID- 27704256 TI - Achieving remission of proteinuria in childhood CKD. AB - BACKGROUND: A multidrug treatment strategy that targets urinary proteins with an angiotensin-converting enzyme (ACE) inhibitor and angiotensin receptor blocker (ARB) up-titrated to the respective maximum tolerated dose combined with intensified blood pressure (BP) control has been found to prevent renal function loss in adults with proteinuric nephropathies. Herein, we investigated the effects of this treatment protocol in the pediatric patient population. METHODS: From May 2002 to September 2014 we included in this observational, longitudinal, cohort study 20 consecutive children with chronic nephropathies and 24-h proteinuria of >200 mg who had received ramipril and losartan up-titrated to the respective maximum approved and tolerated doses [mean ( standard deviation) dose:2.48 (1.37) mg/m2 and 0.61 (0.46) mg/kg daily, respectively]. The primary efficacy endpoint was a >50 % reduction in 24-h proteinuria to <200 mg (remission). Secondary outcomes included changes in proteinuria, serum albumin, BP, and glomerular filtration rate (GFR). RESULTS: Mean (+/- standard deviation) patient age at inclusion was 13.8 +/- 2.8 years, and the median [interquartile range (IQR)] serum creatinine level and proteinuria were 0.7 (0.6-1.0) mg/dl and 690 (379-1270) mg/24 h or 435 (252-711) mg/m2/24 h, respectively. Proteinuria significantly decreased by month 6 of follow-up, and serum albumin levels increased over a median follow-up period of 78 (IQR 39-105) months. In the nine children who achieved remission, proteinuria reduction persisted throughout the whole follow-up without rebounds. The GFR improved in those children who achieved remission and worsened in those who did not. The mean GFR slopes differed significantly between these two groups (p < 0.05), being positive in those children with remission and negative in those without remission (+0.023 +/- 0.15 vs.-0.014 +/- 0.23 ml/min/1.73 m2/month, respectively), whereas BP control was similar between the two groups. Hyperkalemia was observed in two children. CONCLUSIONS: Combination therapy with maximum approved doses of ACE inhibitors and ARBs is a safe strategy which may achieve proteinuria remission with kidney function stabilization or even improvement in a substantial proportion of children with proteinuric nephropathies.

AB - The role of radial-endobronchial ultrasound (R-EBUS) assisted transbronchial biopsy (TBB) for the diagnosis of peripheral pulmonary lesions is well established. However, no study has addressed its safety and value in hemato oncological patients presenting with non-resolving infiltrates during persistent febrile neutropenia. To assess safety and feasibility of R-EBUS assisted TBB in severe thrombocytopenic and neutropenic patients. Over a period of 18 months, eight patients were assessed with R-EBUS assisted TBB after adequate platelet transfusion. This technique allowed precise localisation and sampling of the pulmonary lesions in seven of eight patients. In the seven patients, R-EBUS assisted TBB enabled treatment optimization. Invasive fungal infection was diagnosed in four patients, idiopathic acute fibrinous and organising pneumonia in three patients, and a granulomatous inflammation of undetermined origin in one patient. Importantly, no complications, such as bleeding, were observed. R-EBUS assisted TBB is a promising and safe procedure for the evaluation of nonresolving pulmonary infiltrates in febrile neutropenic hemato-oncological patients.

AB - OPINION STATEMENT: While the diagnosis of migraine in children is generally straightforward, treatment can seem complex with a number of medication choices, many of which are used "off label." Patients with intermittent migraines can often be managed with ibuprofen or naproxen taken as needed. Unfortunately, by the time that children present to our practice, they have often tried these medications without improvement. Triptans are frequently prescribed to these patients with good success. It is important to make the patient aware of the possible associated serotonergic reactions. If the patient is having more than one headache per week or the headaches are prolonged, prophylactic treatment is indicated. In our practice, the overwhelming majority of these patients will be treated with amitriptyline or topiramate. We generally allow side effect tolerability to guide our choice of medication. Cyproheptadine is often used in younger patients as it comes in a liquid form. There is evidence supporting the use of propranolol, though the potential worsening of underlying asthma symptoms may limit its use, and sodium valproate, which must be used with caution in female patients of childbearing age due to significant teratogenicity risks. Other prophylactic treatments with less robust evidence include the antiepileptic drugs gabapentin, zonisamide, and levetiracetam; calcium channel blockers such as verapamil and amlodipine; and the angiotensin receptor blocking agent candasartin (not available in the USA). Almost all patients in our practice are advised to take magnesium supplementation. Magnesium is a supplement with relatively few adverse effects and good evidence for improvement of migraine symptoms. We evaluate lifestyle issues and comorbidities in all our patients. Ignoring these will make successful treatment near impossible. Good sleep, adequate hydration, appropriate diet, and exercise are vitally important. Finally, most of our patients benefit from a psychology evaluation with cognitive behavioral therapy. Stress management and biofeedback are tremendously helpful in improving quality of life in migraineurs. PMID- 27704259 TI - The Emulsified PFC Oxycyte(r) Improved Oxygen Content and Lung Injury Score in a Swine Model of Oleic Acid Lung Injury (OALI). AB - PURPOSE: Perfluorocarbons (PFCs) can transport 50 times more oxygen than human plasma. Their properties may be advantageous in preservation of tissue viability in oxygen-deprived states, such as in acute lung injury. We hypothesized that an intravenous dose of the PFC emulsion Oxycyte(r) would improve tissue oxygenation and thereby mitigate the effects of acute lung injury. METHODS: Intravenous oleic acid (OA) was used to induce lung injury in anesthetized and instrumented Yorkshire swine assigned to three experimental groups: (1) PFC post-OA received Oxycyte(r) (5 ml/kg) 45 min after oleic acid-induced lung injury (OALI); (2) PFC pre-OA received Oxycyte(r) 45 min before OALI; and (3) Controls which received equivalent dose of normal saline. Animals were observed for 3 h after OALI began, and then euthanized. RESULTS: The median survival times for PFC post-OA, PFC pre OA, and control were 240, 87.5, and 240 min, respectively (p = 0.001). Mean arterial pressure and mean pulmonary arterial pressure were both higher in the PFC post-OA (p < 0.001 for both parameters). Oxygen content was significantly different between PFC post-OA and the control (p = 0.001). Histopathological grading of lung injury indicated that edema and congestion was significantly less severe in the PFC post-OA compared to control (p = 0.001). CONCLUSION: The intravenous PFC Oxycyte(r) improves blood oxygen content and lung histology when used as a treatment after OALI, while Oxycyte(r) used prior to OALI was associated with increased mortality. Further exploration in other injury models is indicated. PMID- 27704260 TI - Axillary web syndrome is not a risk factor for lymphoedema after 10 years of follow-up. AB - OBJECTIVE: The objective of this study was to evaluate the association between axillary web syndrome and the development of lymphoedema after 10 years of follow up. METHODOLOGY: A prospective observational study in a hospital cohort of women diagnosed with breast cancer and treated at a referral centre for cancer. Patients were followed according to the routine of the hospital's physical therapy service. In addition, a review of medical records was conducted for the period between 5 and 10 years of follow-up. Data on patient characteristics, treatment, tumour and postoperative complications were collected. RESULTS: In all, 964 patients were included, mostly <65 years old (75 %) and classified as being overweight (68 %). Disease was diagnosed as being up to stage IIA in 54.9 % of the cases; 65.1% underwent mastectomy and 83.8% had total axillary dissection. As adjuvant treatment, 61 % underwent chemotherapy, 63.5 % radiotherapy and 68 % hormone therapy. Among surgical complications, 62.6 % of patients had seroma, 40.7 % had necrosis, 35.9 % axillary web syndrome and 31.4 % lymphoedema. There was no association between axillary web syndrome and the development of lymphoedema (OR = 0.87, 95 % CI 0.65 to 1.15, p = 0.329). CONCLUSION: The occurrence of axillary web syndrome was not a risk factor for lymphoedema after 10 years of follow-up. PMID- 27704261 TI - Do-not-resuscitate consent signed by patients indicates a more favorable quality of end-of-life care for patients with advanced cancer. AB - PURPOSE: Do-not-resuscitate (DNR) consent is crucial in end-of-life (EOL) care for patients with advanced cancer. However, DNR consents signed by patients (DNR P) and surrogates (DNR-S) reflect differently on patient autonomy and awareness. METHODS: This retrospective study enrolled advanced cancer patients treated at National Taiwan University Hospital, Hsin-Chu Branch between 2012 and 2014. Patients who signed DNR consent at other hospitals were excluded; the remaining patients were subsequently classified into DNR-S and DNR-P groups. RESULTS: We enrolled 1495 patients. The most prevalent primary cancers were hepato-biliary pancreatic (26.9 %), lung (16.3 %), and colorectal (14.0 %) cancers. We classified 965 (64.5 %) and 530 (35.5 %) patients into the DNR-S and DNR-P groups, respectively. Significant differences were observed between both groups regarding gender (p = 0.002), age (p < 0.001), and the Eastern Cooperative Oncology Group performance (p < 0.001) and educational (p < 0.001) status levels. The median survival times after DNR consent signature were 5.0 days (95 % confidence interval [CI] 4.4-5.6 days) and 14.0 days (95 % CI 12.1-15.9 days) in the DNR-S and DNR-P groups, respectively (p < 0.001). The median good death evaluation (GDE) scores were 5.4 (95 % CI 4.9-6.0) and 13.7 (95 % CI 12.7-14.6) in the DNR-S and DNR-P groups, respectively (p < 0.001). Univariate and multivariate analyses revealed that DNR-S was an independent factor for significantly low GDE scores (i.e., poor EOL care quality). CONCLUSION: The DNR concept is emerging; however, the DNR-P percentage remains low (35.6 %) in patients with advanced cancer. DNR-P significantly improves the EOL care quality. PMID- 27704262 TI - Risk factors for same-admission mortality after pathologic fracture secondary to metastatic cancer. AB - PURPOSE: The skeleton is the third most common site of cancer metastases. Approximately 10 % of patients with bone metastases will develop a pathologic fracture, with significant associated morbidity and mortality. The purpose of this study was to identify risk factors for same-admission mortality after pathologic fractures secondary to metastatic cancer. METHODS: The Nationwide Inpatient Sample database was queried from 2002 to 2013 for hospitalized patients with diagnoses of pathologic fracture and a primary cancer at high risk for skeletal metastasis. Univariate and multivariate analyses were performed to determine risk factors associated with same-admission mortality after fracture. RESULTS: A total of 371,163 patients were identified. The spine was the most common site of pathologic fracture (68.0 %) followed by lower extremity (25.0 %) and upper extremity (8.7 %). The following factors were independently associated with increased mortality (p < 0.001): cancer of lung or unspecified location; fracture of upper or lower extremity; male gender; age >=65; non-Medicare insurance; coexisting congestive heart failure, chronic pulmonary disease, renal failure, or liver disease; and postoperative surgical site infection, acute myocardial infarction, pulmonary embolism, or pneumonia. Closed reductions were associated (p < 0.001) with increased mortality while open or percutaneous surgical treatments were protective (p < 0.001) against mortality. CONCLUSIONS: Pathologic fractures are a devastating consequence of metastatic bone disease, contributing significantly to morbidity and mortality. Numerous demographic and medical factors are associated with increased same-admission mortality. This data is useful for counseling patients with skeletal metastatic disease and should be taken into consideration when conducting routine skeletal surveillance in patients with metastatic cancer. PMID- 27704263 TI - Mathematical Model of the Dynamics of Fish, Waterbirds and Tourists in the Djoudj National Park, Senegal. AB - In the present paper, we propose and analyze a harvested predator-prey model that incorporates the dynamics of tourists in the Djoudj National Park of Birds, Senegal. The model describes the impact of migration of waterbirds and seasonal fishing on the global coexistence of species in the site of the Djoudj. By the Mahwin continuation theorem of coincidence degree theory, we investigate the existence of a positive periodic solution. The global asymptotic stability is discussed by constructing a suitable Lyapunov functional. Some computational results are also addressed. PMID- 27704264 TI - Analysis of molecular alterations in laterally spreading tumors of the colorectum. AB - BACKGROUND: Colorectal laterally spreading tumors (LSTs) are classified into LST Gs and LST-NGs, according to macroscopic findings. In the present study, we determined the genetic and epigenetic alterations within colorectal LSTs and protruding adenomas. METHODS: A crypt isolation method was used to isolate DNA from tumors and normal glands of 73 macroscopically verified colorectal LSTs (histologically defined adenomas; 38 LST-Gs and 35 LST-NGs) and 36 protruding adenomas. The DNA was processed using polymerase chain reaction (PCR) microsatellite assays, single-strand conformation polymorphism (SSCP) assays, and pyrosequencing to detect chromosomal allelic imbalance (AI), mutations in APC, KRAS, and TP53, and the methylation of MLH1, MGMT, CDKN2A, HPP1, RASSF2A, SFRP1, DKK1, ZFP64, and SALL4 genes. In addition, methylation status was examined using the following set of markers: MIN1, MINT2, MINT31, MLH1, and CDKN2A (with classification of negative/low and high). Microsatellite instability (MSI) was also examined. RESULTS: 5q AI and methylation of the SFRP1 and SALL4 genes were common molecular events in both LST-Gs and LST-NGs. Neither MSI nor mutations in BRAF ware observed in the LSTs. TP53 mutations were rarely found in LSTs. The frequencies of KRAS and APC mutations and the methylation levels of ZFP64, RASSF2A, and HPP1 genes were significantly higher in LST-Gs than in LST-NGs. Protruding adenomas showed alterations common to LST-Gs. Negative/low methylation status was common among the three types of tumors. CONCLUSION: Combined genetic and epigenetic data suggested that the molecular mechanisms of tumorigenesis were different between LST-Gs and LST-NGs. PMID- 27704265 TI - Biliary carcinogenesis in pancreaticobiliary maljunction. AB - Pancreaticobiliary maljunction (PBM) is a congenital malformation in which the pancreatic and bile ducts join anatomically outside the duodenal wall. Because of the excessive length of the common channel in PBM, sphincter action does not directly affect the pancreaticobiliary junction, which allows pancreatic juice to reflux into the biliary tract. According to the results of a nationwide survey, bile duct and gallbladder cancers were found in 6.9 and 13.4 % of adult patients with congenital biliary dilatation, respectively, and in 3.1 and 37.4 % of those with PBM without biliary dilatation, respectively. Biliary tract cancers develop about 15-20 years earlier in patients with PBM than in individuals without PBM; they sometimes develop as double cancers. Carcinogenesis is strongly associated with stasis of bile intermingled with refluxed pancreatic juice. Epithelial cells in the biliary tract of PBM patients are under constant attack from activated pancreatic enzymes, increased secondary bile acids, or other mutagens. This can result in hyperplastic change with increased cell proliferation activity, and in turn, oncogene and/or tumor suppressor gene mutations in the epithelia, leading to the biliary tract carcinogenesis. The carcinogenesis of biliary tract cancer accompanying PBM is considered to involve a hyperplasia-dysplasia-carcinoma sequence induced by chronic inflammation caused by the reflux of pancreatic juice into the biliary tract, which differs from the adenoma-carcinoma sequence or the de novo carcinogenesis associated with biliary tract cancers in the population without PBM. Patients with a relatively long common channel have a similar, albeit slightly lower, risk for gallbladder cancer compared with PBM patients. PMID- 27704266 TI - Phase 2 study of lenvatinib in patients with advanced hepatocellular carcinoma. AB - BACKGROUND: Lenvatinib is an oral inhibitor of vascular endothelial growth factor receptor 1-3, fibroblast growth factor receptor 1-4, platelet-derived growth factor receptor alpha, RET, and KIT. This phase 2, single-arm, open-label multicenter study evaluated lenvatinib in advanced hepatocellular carcinoma (HCC). METHODS: Patients with histologically/clinically confirmed advanced HCC who did not qualify for surgical resection or local therapies received lenvatinib at a dosage of 12 mg once daily (QD) in 28-day cycles. The primary efficacy endpoint was time to progression (TTP) per modified Response Evaluation Criteria in Solid Tumors v1.1; secondary efficacy endpoints included objective response rate (ORR), disease control rate (DCR), and overall survival (OS). RESULTS: Between July 2010 and June 2011, 46 patients received lenvatinib at sites across Japan and Korea. The median TTP, as determined by independent radiological review, was 7.4 months [95 % confidence interval (CI): 5.5-9.4]. Seventeen patients (37 %) had partial response and 19 patients (41 %) had stable disease (ORR: 37 %; DCR: 78 %). Median OS was 18.7 months (95 % CI: 12.7-25.1). The most common any-grade adverse events (AEs) were hypertension (76 %), palmar-plantar erythrodysesthesia syndrome (65 %), decreased appetite (61 %), and proteinuria (61 %). Dose reductions and discontinuations due to AEs occurred in 34 (74 %) and 10 patients (22 %), respectively. Median body weight was lower in patients with an early (<30 days) dose withdrawal or reduction than in those without. CONCLUSIONS: Lenvatinib 12-mg QD showed clinical activity and acceptable toxicity profiles in patients with advanced HCC, but early dose modification was necessary in patients with lower body weight. Further development of lenvatinib in HCC should consider dose modification by body weight. TRIAL REGISTRATION ID: www.ClinicalTrials.gov NCT00946153. PMID- 27704267 TI - MicroRNA-34c-3p promotes cell proliferation and invasion in hepatocellular carcinoma by regulation of NCKAP1 expression. AB - PURPOSE: Our previous miRNA profiling study indicated that microRNA-34c-3p (miR 34c-3p) was overexpressed and associated with survival in HCC. This study is aimed to confirm its clinical significance and explore the function and underlying mechanism of miR-34c-3p in HCC. METHODS: We first evaluated miR-34c-3p expression and its relationship with prognosis in HCC patients. We then established stable HCC cell lines with miR-34c-3p overexpression and knockdown by the lentiviral packaging systems and performed the functional assays in vitro and in vivo, respectively. We next identified the target of miR-34c-3p by using microRNA target databases and dual-luciferase assay. Finally, the correlation between the expression of miR-34c-3p and the target gene was analyzed by immunohistochemistry and qRT-PCR in HCC tissues and hepatoma xenografts. RESULTS: Overexpressed miR-34c-3p was confirmed in HCC tissues and significantly associated with poor survival of HCC patients. miR-34c-3p expression was also recognized as an independent risk factor for DFS and OS in multivariate analysis. Ectopic expression of miR-34c-3p significantly promotes the proliferation, colony formation, invasion and cell cycle regression of HCC cell lines. Knockdown of miR 34c-3p remarkably blocked hepatoma growth in the xenograft model. miRNA target databases and luciferase reporter assay showed that NCKAP1 was a direct target of miR-34c-3p in HCC cells and the high expression of NCKAP1 in HCC tissues is significantly correlated with low expression of miR-34c-3p and associated with a favorable prognosis of HCC patients. CONCLUSION: The current study demonstrates that miR-34c-3p functions as a tumor promoter by targeting NCKAP1 that is associated with prognosis in HCC. miR-34c-3p and NCKAP1 may be new potential molecular targets for HCC therapy. PMID- 27704269 TI - Linked CD4 T Cell Help: Broadening Immune Attack Against Cancer by Vaccination. AB - In the last decade, immunotherapy with monoclonal antibodies targeting immunological check points has become a breakthrough therapeutic modality for solid cancers. However, only up to 50 % of patients benefit from this powerful approach. For others vaccination might provide a plausible addition or alternative. For induction of effective anticancer immunity CD4+ T cell help is required, which is often difficult to induce to self cancer targets because of tolerogenic mechanisms. Our approach for cancer vaccines has been to incorporate into the vaccine design sequences able to activate foreign T cell help, through genetically linking cancer targets to microbial sequences (King et al. in Nat Med 4(11):1281-1286, 1998; Savelyeva et al. in Nat Biotechnol 19(8):760-764, 2001). This harnesses the non-tolerized CD4 T cell repertoire available in patients to help induction of effective immunity against fused cancer antigens. Multiple immune effector mechanisms including antibody, CD8+ T cells as well as CD4 effector T cells can be activated using this strategy. Delivery via DNA vaccines has already indicated clinical efficacy. The same principle of linked T cell help has now been transferred to other novel vaccine modalities to further potentiate immunity against cancer targets. PMID- 27704268 TI - Chemotherapy response and survival of inflammatory breast cancer by hormone receptor- and HER2-defined molecular subtypes approximation: an analysis from the National Cancer Database. AB - PURPOSE: To study the impact of hormone receptor (HR)- and human epidermal growth factor receptor 2 (HER2)-defined subtypes on survival of inflammatory breast cancer (IBC), and to determine whether sensitivity to neoadjuvant chemotherapy (NAC) varies with subtypes in a large IBC population. METHODS: We analyzed 593 IBCs with known HR/HER2 statuses between 2010 and 2011 from National Cancer Database. We compared pathologic complete response (pCR) rates among four molecular subtypes by Chi-square test. Overall survival (OS) was compared among four subtypes and patients with or without pCR using log-rank test. Multivariate Cox model was performed to identify the impact of molecular subtype and other prognostic factors on OS. RESULTS: Of the 593 patients included, 231 (39.0 %) patients had HR+/HER2- tumors, 98 (16.5 %) had HR+/HER2+ disease, 112 (18.9 %) were HR-/HER2 + patients, and 152 (25.6 %) had triple-negative subtype. The pCR rates differed significantly by subtype (P < 0.001): HR-/HER2+ showed the highest, and HR+/HER2- exhibited the lowest. Multivariate analysis showed that triple-negative and HR+/HER2- IBCs had significantly worse survival compared with HR+/HER2+ or HR-/HER2+ subtype (P < 0.01 for all comparisons). Additional factors associated with worse OS included more comorbidities, lack or incomplete surgical resection, absence of radiotherapy, lack of hormone therapy, and more advanced stage. CONCLUSIONS: IBC is an aggressive heterogeneous disease with distinct molecular subtypes associated with differential outcomes and sensitivities to NAC. Unlike in noninflammatory breast cancer, in IBC HR + disease was not associated with favorable prognosis. Triple-negative and HR+/HER2- subtypes are independent predictors for suboptimal OS in IBC. PMID- 27704270 TI - New Structural Templates for Clinically Validated and Novel Targets in Antimicrobial Drug Research and Development. AB - The development of bacterial resistance against current antibiotic drugs necessitates a continuous renewal of the arsenal of efficacious drugs. This imperative has not been met by the output of antibiotic research and development of the past decades for various reasons, including the declining efforts of large pharma companies in this area. Moreover, the majority of novel antibiotics are chemical derivatives of existing structures that represent mostly step innovations, implying that the available chemical space may be exhausted. This review negates this impression by showcasing recent achievements in lead finding and optimization of antibiotics that have novel or unexplored chemical structures. Not surprisingly, many of the novel structural templates like teixobactins, lysocin, griselimycin, or the albicidin/cystobactamid pair were discovered from natural sources. Additional compounds were obtained from the screening of synthetic libraries and chemical synthesis, including the gyrase inhibiting NTBI's and spiropyrimidinetrione, the tarocin and targocil inhibitors of wall teichoic acid synthesis, or the boronates and diazabicyclo[3.2.1]octane as novel beta-lactamase inhibitors. A motif that is common to most clinically validated antibiotics is that they address hotspots in complex biosynthetic machineries, whose functioning is essential for the bacterial cell. Therefore, an introduction to the biological targets-cell wall synthesis, topoisomerases, the DNA sliding clamp, and membrane-bound electron transport-is given for each of the leads presented here. PMID- 27704271 TI - Synthesis of Antibiotics. AB - The synthesis of beta-lactams, tetracyclines, and erythromycins as three of the major families of antibiotics will be described herein. We will describe why these antibiotics were the ultimate synthetic targets in the past and how modern synthetic organic chemistry has evolved to address these challenges with new, improved strategies and methods. An additional aspect we would like to highlight here is the fact that these first syntheses had to be particularly creative as most of the modern synthetic methods were not available at that time, or were developed in the course of these syntheses. PMID- 27704273 TI - Joint Meeting of the German Association of Endocrine Surgeons (CAEK) and the British Association of Endocrine and Thyroid Surgeons (BAETS). PMID- 27704272 TI - Actinobacteria and Myxobacteria-Two of the Most Important Bacterial Resources for Novel Antibiotics. AB - Bacteria have been by far the most promising resource for antibiotics in the past decades and will in all undoubtedly remain an important resource of innovative bioactive natural products in the future. Actinobacteria have been screened for many years, whereas the Myxobacteria have been underestimated in the past. Even though Actinobacteria belong to the Gram-positive and Myxobacteria to the Gram negative bacteria both groups have a number of similar characters, as they both have huge genomes with in some cases more than 10kB and a high GC content and they both can differentiate and have often cell cycles including the formation of spores. Actinobacteria have been used for the antibiotic research for many years, hence it is often discussed whether this resource has now been exhaustively exploited but most of the screening programs from pharmaceutical companies were basing on the cultivation mainly of members of the genus Streptomyces or Streptomyces like strains (e.g., some Saccharopolyspora, Amycolatopsis or Actinomadura species) by use of standard methods so that many of the so called "neglected" Actinobacteria were overlooked the whole time. The present review gives an overview on the state of the art regarding new bioactive compounds with a focus on the marine habitats. Furthermore, the evaluation of Myxobacteria in our ongoing search for novel anti-infectives is highlighted. PMID- 27704274 TI - Risk-adjusted treatment selection and outcome of patients with acute cholecystitis. AB - PURPOSE: Age and comorbidities increase the surgical risk for patients with acute cholecystitis and impact on the initial treatment selection. The aim of this article is the implementation of objective risk criteria that may be used to select the most appropriate treatment. METHODS: We carried out a prospective cohort study of all patients who were admitted to the hospital with a diagnosis of acute cholecystitis during 2014. They were initially allocated to three different treatment groups according to cholecystitis grade, number of days from clinical onset, and surgical risk scores as follows: immediate surgery by sepsis (EmergS), early surgery (EarlyS), or medical treatment group (MedT). Differences in the outcomes between the treatment groups were evaluated using bivariate and logistic regression analyses. RESULTS: A total of 149 patients were admitted; 44 % were >80 years old and 40 % were American Society of Anesthesiologists (ASA) > II. The mortality rate of the series was 0 % in EarlyS, 17 % in MedT, and 19 % in EmergS. The mortality rate was significantly associated with a higher degree of cholecystitis, age, and worse score values in risk scales and Charlson index. Logistic regression identified that the only independent predictors of death at the time of admission were the degree of cholecystitis (OR 2.87, p = 0.018) and the Portsmouth Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (P-POSSUM) score (OR 1.14, p = 0.001). CONCLUSION: The evaluation for the initial treatment in acute cholecystitis should include a systematic determination of the degree of cholecystitis and a surgical risk assessment. Tokyo guideline recommendations should be reviewed. PMID- 27704275 TI - Dynamic quantitative proteomics characterization of TNF-alpha-induced necroptosis. AB - Emerging evidence suggested that necroptosis has essential functions in many human inflammatory diseases, but the molecular mechanisms of necroptosis remain unclear. Here, we employed SILAC quantitatively dynamic proteomics to compare the protein changes during TNF-alpha-induced necroptosis at different time points in murine fibrosarcoma L929 cells with caspase-8 deficiency, and then performed the systematical analysis on the signaling networks involved in the progress using bioinformatics methods. Our results showed that a total of 329, 421 and 378 differentially expressed proteins were detected at three stages of necroptosis, respectively. Gene ontology and ingenuity pathway analysis (IPA) revealed that the proteins regulated at early stages of necroptosis (2, 6 h) were mainly involved in mitochondria dysfunction, oxidative phosphorylation and Nrf-2 signaling, while the expression levels of the proteins related to ubiquitin, Nrf 2, and NF-kappaB pathways were found to have changes at last stages of necroptosis (6, 18 h). Taken together, we demonstrated for the first time that dysfunction of mitochondria and ubiquitin-proteasome signaling contributed to the initiation and execution of necroptosis. These findings may provide clues for the identification of important regulators in necroptosis and the development of novel therapeutic strategies for the related diseases. PMID- 27704276 TI - Identification of cytotoxic mediators and their putative role in the signaling pathways during docosahexaenoic acid (DHA)-induced apoptosis of cancer cells. AB - Docosahexaenoic acid (DHA), an important w-3 fatty acid exhibits differential behavior in cancer cells of neural origin when compared to that in normal healthy astrocytes. Treatment of C6 glioma and SH-SY5Y cell lines and primary astrocytes, representing the neoplastic cells and normal healthy cells respectively, with 100 uM DHA for 24 h showed significant loss of cell viability in the both the cancer cells as determined by MTT assay, whereas the primary astrocytes cultures were unaffected. Such loss of cell viability was due to apoptosis as confirmed by TUNEL staining and caspase-3 activation in cancer cells. Proteomic approach, employing 2-dimensional gel electrophoresis (2DE), difference gel electrophoresis (DIGE), and MALDI-TOF-TOF analysis identified six proteins which unlike in the astrocytes, were differently altered in the cancer cells upon exposure to DHA, suggesting their putative contribution in causing apoptosis in these cells. Of these, annexin A2, calumenin, pyruvate kinase M2 isoform, 14-3-3zeta were downregulated while aldo keto reductase-1B8 (AKR1B8) and glutathione-S transferase P1 subunit (GSTP1) showed upregulation by DHA in the cancer cells. siRNA-mediated knockdown of AKR1B8 and GSTP1 inhibit DHA-induced apoptosis confirming their role in apoptotic process. Furthermore, western blot analysis identified upregulation of PPARalpha and the MAP kinases, JNK and p38 as well as increased ROS production selectively in the cell lines. Results suggest that DHA selectively induces apoptosis in the neural cell lines by regulating the expression of the above proteins to activate multiple apoptotic pathways which in association with excess ROS and activated MAPKs promote cell death. PMID- 27704277 TI - Branch regeneration induced by sever damage in the brown alga Dictyota dichotoma (dictyotales, phaeophyceae). AB - Tissue wounds are mainly caused by herbivory, which is a serious threat for macro algae, and brown algae are known to regenerate branches or buds in response to wounding. In the present paper, we describe a branch regeneration system, induced by sever damage, in the brown alga Dictyota dichotoma. Segmentations of juvenile thalli induced branch regenerations unless explants possessed apical cells. Apical excisions in distinct positions elucidated that disruption of an apical cell or disconnection of tissue with an apical cell triggered the branch regeneration. Furthermore, spatial positions of regenerated branches seemed to be regulated by the apical region, which was assumed to generate inhibitory effects for lateral branch regeneration. Mechanical incision, which disrupted tissue continuity with the apical region, induced branch regeneration preferentially below the incision. Although we were unable to identify the candidate inhibitory substance, our results suggested that the apical region may have an inhibitory effect on lateral branch regeneration. Additionally, observations of branch regeneration showed that all epidermal cells in D. dichotoma possess the ability to differentiate into apical cells, directly. This may be the first report of algal transdifferentiation during the wound-stress response. PMID- 27704278 TI - Comparison of headspace-oxylipin-volatilomes of some Eastern Himalayan mosses extracted by sample enrichment probe and analysed by gas chromatography-mass spectrometry. AB - Mosses have an inherent adaptability against different biotic and abiotic stresses. Oxylipins, the volatile metabolites derived from polyunsaturated fatty acids (PUFAs), play a key role in the chemical defence strategy of mosses. In the present study, a comparative survey of these compounds, including an investigation into their precursor fatty acids (FAs), was carried out for the first time on the mosses Brachymenium capitulatum (Mitt.) Paris, Hydrogonium consanguineum (Thwaites & Mitt.) Hilp., Barbula hastata Mitt., and Octoblepharum albidum Hedw. collected from the Eastern Himalayan Biodiversity hotspot. Their headspace volatiles were sampled using a high-efficiency sample enrichment probe (SEP) and were characterized by gas chromatography-mass spectrometric analysis. FAs from neutral lipid (NL) and phospholipid (PL) fractions were also evaluated. Analysis of the oxylipin volatilome revealed the generation of diverse metabolites from C5 to C18, dominated by alkanes, alkenes, saturated and unsaturated alcohols, aldehydes, ketones and cyclic compounds, with pronounced structural variations. The C6 and C8 compounds dominated the total volatilome of all the samples. Analyses of FAs from membrane PL and storage NL highlighted the involvement of C18 and C20 PUFAs in oxylipin generation. The volatilome of each moss is characterized by a 'signature oxylipin mixture'. Quantitative differences in the C6 and C8 metabolites indicate their phylogenetic significance. PMID- 27704279 TI - Improvement of the insertion axis for cochlear implantation with a robot-based system. AB - It has previously reported that alignment of the insertion axis along the basal turn of the cochlea was depending on surgeon' experience. In this experimental study, we assessed technological assistances, such as navigation or a robot-based system, to improve the insertion axis during cochlear implantation. A preoperative cone beam CT and a mastoidectomy with a posterior tympanotomy were performed on four temporal bones. The optimal insertion axis was defined as the closest axis to the scala tympani centerline avoiding the facial nerve. A neuronavigation system, a robot assistance prototype, and software allowing a semi-automated alignment of the robot were used to align an insertion tool with an optimal insertion axis. Four procedures were performed and repeated three times in each temporal bone: manual, manual navigation-assisted, robot-based navigation-assisted, and robot-based semi-automated. The angle between the optimal and the insertion tool axis was measured in the four procedures. The error was 8.3 degrees +/- 2.82 degrees for the manual procedure (n = 24), 8.6 degrees +/- 2.83 degrees for the manual navigation-assisted procedure (n = 24), 5.4 degrees +/- 3.91 degrees for the robot-based navigation-assisted procedure (n = 24), and 3.4 degrees +/- 1.56 degrees for the robot-based semi-automated procedure (n = 12). A higher accuracy was observed with the semi-automated robot based technique than manual and manual navigation-assisted (p < 0.01). Combination of a navigation system and a manual insertion does not improve the alignment accuracy due to the lack of friendly user interface. On the contrary, a semi-automated robot-based system reduces both the error and the variability of the alignment with a defined optimal axis.

AB - Evidence of misfolded wild-type superoxide dismutase 1 (SOD1) has been detected in spinal cords of sporadic ALS (sALS) patients, suggesting an etiological relationship to SOD1-associated familial ALS (fALS). Given that there are currently a number of promising therapies under development that target SOD1, it is of critical importance to better understand the role of misfolded SOD1 in sALS. We previously demonstrated the permissiveness of the G85R-SOD1:YFP mouse model for MND induction following injection with tissue homogenates from paralyzed transgenic mice expressing SOD1 mutations. This prompted us to examine whether WT SOD1 can self-propagate misfolding of the G85R-SOD1:YFP protein akin to what has been observed with mutant SOD1. Using the G85R-SOD1:YFP mice, we demonstrate that misfolded conformers of recombinant WT SOD1, produced in vitro, induce MND with a distinct inclusion pathology. Furthermore, the distinct pathology remains upon successive passages in the G85R-SOD1:YFP mice, strongly supporting the notion for conformation-dependent templated propagation and SOD1 strains. To determine the presence of a similar misfolded WT SOD1 conformer in sALS tissue, we screened homogenates from patients diagnosed with sALS, fALS, and non-ALS disease in an organotypic spinal cord slice culture assay. Slice cultures from G85R-SOD1:YFP mice exposed to spinal homogenates from patients diagnosed with ALS caused by the A4V mutation in SOD1 developed robust inclusion pathology, whereas spinal homogenates from more than 30 sALS cases and various controls failed. These findings suggest that mutant SOD1 has prion-like attributes that do not extend to SOD1 in sALS tissues. PMID- 27704283 TI - Rewiring host activities for synthetic circuit production: a translation view. AB - The expression of synthetic circuits in host organisms, or chassis, is a key aspect of synthetic biology. Design adjustments made for maximal production may negatively affect the central metabolism and biosynthetic activities of the chassis host. Here, we review recent attempts to modulate synthetic circuit design for optimal production and present models that precisely capture the trade off between circuit production and chassis growth. We also present emerging concepts for full orthogonalization of synthetic productivity and its decoupling from the endogenous biosynthetic activities of the cell, opening new routes towards robust synthetic circuit expression. PMID- 27704281 TI - Mir-223 regulates the number and function of myeloid-derived suppressor cells in multiple sclerosis and experimental autoimmune encephalomyelitis. AB - Myeloid-derived cells play important modulatory and effector roles in multiple sclerosis (MS) and its animal model, experimental autoimmune encephalomyelitis (EAE). Myeloid-derived suppressor cells (MDSCs) are immature myeloid cells, composed of monocytic (MO) and polymorphonuclear (PMN) fractions, which can suppress T cell activities in EAE. Their role in MS remains poorly characterized. We found decreased numbers of circulating MDSCs, driven by lower frequencies of the MO-MDSCs, and higher MDSC expression of microRNA miR-223 in MS versus healthy subjects. To gain mechanistic insights, we interrogated the EAE model. MiR-223 knock out (miR-223-/-) mice developed less severe EAE with increased MDSC numbers in the spleen and spinal cord compared to littermate controls. MiR-223-/- MO MDSCs suppressed T cell proliferation and cytokine production in vitro and EAE in vivo more than wild-type MO-MDSCs. They also displayed an increased expression of critical mediators of MDSC suppressive function, Arginase-1(Arg1), and the signal transducer and activator of transcription 3 (Stat3), which herein, we demonstrate being an miR-223 target gene. Consistently, MDSCs from MS patients displayed decreased STAT3 and ARG1 expression compared with healthy controls, suggesting that circulating MDSCs in MS are not only reduced in numbers but also less suppressive. These results support a critical role for miR-223 in modulating MDSC biology in EAE and in MS and suggest potential novel therapeutic applications. PMID- 27704284 TI - Thoracic spine morphology of a pseudo-biped animal model (kangaroo) and comparisons with human and quadruped animals. AB - PURPOSE: Based on the structural anatomy, loading condition and range of motion (ROM), no quadruped animal has been shown to accurately mimic the structure and biomechanical function of the human spine. The objective of this study is to quantify the thoracic vertebrae geometry of the kangaroo, and compare with adult human, pig, sheep, and deer. METHODS: The thoracic vertebrae (T1-T12) from whole body CT scans of ten juvenile kangaroos (ages 11-14 months) were digitally reconstructed and geometric dimensions of the vertebral bodies, endplates, pedicles, spinal canal, processes, facets and intervertebral discs were recorded. Similar data available in the literature on the adult human, pig, sheep, and deer were compared to the kangaroo. A non-parametric trend analysis was performed. RESULTS: Thoracic vertebral dimensions of the juvenile kangaroo were found to be generally smaller than those of the adult human and quadruped animals. The most significant (p < 0.001) correlations (Rho) found between the human and kangaroo were in vertebrae and endplate dimensions (0.951 <= Rho <= 0.963), pedicles (0.851 <= Rho <= 0.951), and inter-facet heights (0.891 <= Rho <= 0.967). The deer displayed the least similar trends across vertebral levels. CONCLUSIONS: Similarities in thoracic spine vertebral geometry, particularly of the vertebrae, pedicles and facets may render the kangaroo a more clinically relevant human surrogate for testing spinal implants. The pseudo-biped kangaroo may also be a more suitable model for the human thoracic spine for simulating spine deformities, based on previously published similarities in biomechanical loading, posture and ROM. PMID- 27704282 TI - Climbing fiber-Purkinje cell synaptic pathology in tremor and cerebellar degenerative diseases. AB - Changes in climbing fiber-Purkinje cell (CF-PC) synaptic connections have been found in the essential tremor (ET) cerebellum, and these changes are correlated with tremor severity. Whether these postmortem changes are specific to ET remains to be investigated. We assessed CF-PC synaptic pathology in the postmortem cerebellum across a range of degenerative movement disorders [10 Parkinson's disease (PD) cases, 10 multiple system atrophy (MSA) cases, 10 spinocerebellar ataxia type 1 (SCA1) cases, and 20 ET cases] and 25 controls. We observed differences in terms of CF pathological features across these disorders. Specifically, PD cases and ET cases both had more CFs extending into the parallel fiber (PF) territory, but ET cases had more complex branching and increased length of CFs in the PF territory along with decreased CF synaptic density compared to PD cases. MSA cases and SCA1 cases had the most severely reduced CF synaptic density and a marked paucity of CFs extending into the PF territory. Furthermore, CFs in a subset of MSA cases formed collateral branches parallel to the PC layer, a feature not seen in other diagnostic groups. Using unsupervised cluster analysis, the cases and controls could all be categorized into four clusters based on the CF pathology and features of PC pathology, including counts of PCs and their axonal torpedoes. ET cases and PD cases co-segregated into two clusters, whereas SCA1 cases and MSA cases formed another cluster, separate from the control cluster. Interestingly, the presence of resting tremor seemed to be the clinical feature that separated the cases into the two ET-PD clusters. In conclusion, our study demonstrates that these degenerative movement disorders seem to differ with respect to the pattern of CF synaptic pathology they exhibit. It remains to be determined how these differences contribute to the clinical presentations of these diseases. PMID- 27704285 TI - Cobb-1 versus cobb-to-cobb anterior fusion for adolescent idiopathic scoliosis Lenke 5C curves: a radiological comparative study. AB - PURPOSE: Anterior fusion is a well-established procedure for the treatment of Lenke 5C adolescent idiopathic scoliosis (AIS). This retrospective study aimed to assess preoperative and postoperative radiographic differences between the conventional anterior fusion and anterior short fusions (ASF) in Lenke 5C AIS. METHODS: Radiographic data of 42 consecutive cases of Lenke 5C AIS, which were surgically treated through anterior segmental fusion, were analyzed retrospectively. Patients have been divided into two groups: C group (n = 19) treated by the conventional fusion from the proximal end vertebra to the distal end vertebra of the main curve and C-1 group (n = 23) treated by ASF, sparing the lowest end vertebra of the main curve. Cobb angles of main curve, apical vertebra tilt, C7 coronal tilt, lowest instrumented vertebra angle (LIV angle), LIV adjacent level disc angulation (LIVDA), and the first uninstrumented vertebra angle (FUV angle) were measured on anteroposterior radiographs of the entire spine. LIVDA, FUV wedging, and rotation were measured on stretch films. C7 sagittal tilt, lumbar lordosis, thoracic kyphosis, and proximal kyphosis junction were measured on lateral radiographs of the entire spine. Repeated-measures analysis of variance and fisher test were used for the statistical analysis. RESULTS: The preoperative main curve was 39.9 +/- 9.1 degrees in the C group vs. (versus) 42.8 +/- 11.8 degrees in the C-1 group. At a mean follow-up of 26.2 months (range 10.5-66.3 months), postoperative main curve improved of 75.8 +/- 21.2 % (10.4 +/- 9.2 degrees , p < 0.001) in the C group and of 52.7 +/- 18.7 % (20.1 +/- 8.1 degrees , p < 0.001) in the C-1 group. All parameters improved except the LIVDA, which was slightly impaired, especially in the C-1 group with 5.6 +/- 4.2 degrees vs. 4.4 +/- 2.2 degrees in the C group. On stretch films, FUV rotation was the only parameter to differ; it was graded at 1 +/- 0.7 in the C-1 group vs. 0.6 +/- 0.5 in the C group (p = 0.04). No disk obliquity just under the future instrumentation and equivalent FUV wedging were found in any of the two groups. CONCLUSIONS: The conventional anterior fusion and ASF give equivalent correction in Lenke 5C AIS, but ASF seems to induce adding-on of the disk below the LIV. FUV rotation on stretch films does not seem to be a predictive factor of postoperative radiological outcome.

PMID- 27704288 TI - Letter to the Editor Regarding: Patterns and Impact of Hypoglycemia, Hyperglycemia, and Glucose Variability on Inpatients with Insulin-Treated Cystic Fibrosis-Related Diabetes. PMID- 27704286 TI - Herniectomy versus herniectomy with the DIAM spinal stabilization system in patients with sciatica and concomitant low back pain: results of a prospective randomized controlled multicenter trial. AB - PURPOSE: To investigate the short and medium term efficacy and patient outcomes of DIAM spinal stabilization system on back pain, disability, leg pain and quality of life. METHODS: 165 patients were enrolled; 146 patients with a single level disc herniation (L2 to L5) were randomized: 75 investigational (herniectomy and DIAM) and 71 control (herniectomy alone) treated and followed up for 24 months. RESULTS: Significant improvements overtime (P < 0.001) in both groups but not significantly different between groups for visual analog scale (VAS) back pain at 6 months (investigational -3.97 +/- 2.55 vs control-3.37 +/- 3.15, P = 0.228) and Oswestry Disability Index (ODI) at 12 months (-38.55 +/- 20.10 vs 37.19 +/- 22.61, P = 0.719). For both outcomes, there was no statistically significant difference between the groups, at all postoperative time points. Although the enrolment ended before the intended sample size (308 patients) was reached, the number of patients reaching the VAS back pain minimally clinically important difference (MCID) of >=2.2 at 6 months was higher in the investigational (79.4 % vs control 57.1 %, P = 0.008). These results were sustained throughout 24 months (82.8 vs 64.4 %, P < 0.05). In average, surgical duration (P < 0.001), blood loss (P = 0.029) and skin incision (P < 0.001) in the investigational were 10 min longer, 22.5 ml greater and 2.0 cm wider than control group (median values). Improved tertiary outcomes from BL to 24 mo in both groups (investigational vs control): VAS leg pain (mean decrease -6.41 +/- 2.57 to -6.41 vs -5.61 +/- to -3.30); improved quality of life (SF-36: 20.68 +/- 9.44 vs 16.90 +/- 10.74); pain medication reduction: 56.7 vs 47.9 %; return to work: 45.7 vs 38.0 %. Adverse event rates: 68.5 % investigational and 66.2 % control. CONCLUSIONS: This is the first randomized controlled trial to report equivalent efficacy and safety of herniectomy with or without DIAM spinal stabilizing device. Leg pain, back pain and the level of disability were not significantly different between groups; however, number of patients reaching the MCID for back pain was significantly higher in the investigational group at 6 through 24 months. PMID- 27704289 TI - Preadmission schooling context helps to predict examination performance throughout medical school. AB - This study investigates the effects of socioeconomic status and schooling on the academic attainment of a cohort of students at a single medical school (N = 240). Partial least squares structural equation modelling was used to explore how students' summative assessment scores over 4 years of medical school were affected by: attainment in secondary school examinations (GCSEs and A-levels); the Income Deprivation Affecting Children Index (IDACI) rank associated with students' home postcodes; the performance of students' A-level institutions, measured as the percentage of A-level students achieving 3 A-levels at AAB or higher in two or more facilitating subjects. The effects were consistent across time; the final linear regression model used students' cumulative scores (the basis of the medical school's UK Foundation Programme submission) as the dependent variable. The final model fit was quite poor (R2 = .184, n = 178). IDACI Rank was non-significant and excluded from the final model. Both GCSE (.340, p < .001) and A-level (.204, p < .005) scores were associated with increasing Cumulative Score; School Performance was associated with decreasing Cumulative Score (-.159, p < .05). This study confirmed the predictive validity of prior academic attainment and found the same inverse relationship between schooling and medical course performance as previous studies. The study found no evidence that socioeconomic background affects course performance; however, students admitted to medicine from poorly performing schools achieve higher academic attainment throughout the course than students admitted from better performing schools with the same grades. Schooling could be taken into account for admissions purposes. PMID- 27704290 TI - Do personality traits assessed on medical school admission predict exit performance? A UK-wide longitudinal cohort study. AB - Traditional methods of assessing personality traits in medical school selection have been heavily criticised. To address this at the point of selection, "non cognitive" tests were included in the UK Clinical Aptitude Test, the most widely used aptitude test in UK medical education (UKCAT: http://www.ukcat.ac.uk/ ). We examined the predictive validity of these non-cognitive traits with performance during and on exit from medical school. We sampled all students graduating in 2013 from the 30 UKCAT consortium medical schools. Analysis included: candidate demographics, UKCAT non-cognitive scores, medical school performance data-the Educational Performance Measure (EPM) and national exit situational judgement test (SJT) outcomes. We examined the relationships between these variables and SJT and EPM scores. Multilevel modelling was used to assess the relationships adjusting for confounders. The 3343 students who had taken the UKCAT non cognitive tests and had both EPM and SJT data were entered into the analysis. There were four types of non-cognitive test: (1) libertariancommunitarian, (2) NACE-narcissism, aloofness, confidence and empathy, (3) MEARS-self-esteem, optimism, control, self-discipline, emotional-nondefensiveness (END) and faking, (4) an abridged version of 1 and 2 combined. Multilevel regression showed that, after correcting for demographic factors, END predicted SJT and EPM decile. Aloofness and empathy in NACE were predictive of SJT score. This is the first large-scale study examining the relationship between performance on non-cognitive selection tests and medical school exit assessments. The predictive validity of these tests was limited, and the relationships revealed do not fit neatly with theoretical expectations. This study does not support their use in selection. PMID- 27704291 TI - Dynamic measures of skeletal muscle dialysate and plasma amino acid concentration in response to exercise and nutrient ingestion in healthy adult males. AB - Nutrient stimulation of muscle protein synthesis (MPS) is regulated by the change in extracellular essential amino acid (EAA) concentration. In vivo microdialysis (MD) is a minimally invasive sampling technique, capable of sampling solute in the interstitial space of a target tissue. In a contralateral limb design (REST vs. EX), this study utilised in vivo MD to examine the change in skeletal muscle dialysate amino acid concentration following ingestion of whey protein isolate (WPI) and flavoured water (CON). Four male subjects undertook unilateral, concentric lower limb knee extensor resistance exercise (RE) on two occasions. After RE, an MD catheter (CMA 63) was inserted into m. vastus lateralis of the exercise and resting leg and sampled serially over 7 h. Following a 2.5 h equilibration period subjects consumed either 0.55 g/kg WPI or CON. Peak plasma EAA (2656 +/- 152 uM) preceded the peak in dialysate EAA (2345 +/- 164 uM) by 30 min in response to WPI ingestion; however, the post-prandial elevation in dialysate EAA extended beyond that of the plasma. This resulted in no difference in the dialysate EAA area under the curve (DeltaAUC270) relative to plasma in response to WPI ingestion [220 +/- 29 vs. 206 +/- 7.9 mmol min/L (p = 0.700)]. A bout of unilateral lower limb RE had no effect of the subsequent dialysate amino acid concentration in response to either WPI or CON ingestion. These data represent a novel report describing the time course and magnitude of change in skeletal muscle dialysate concentration of key nutrient regulators of MPS sampled by in vivo MD, in response to nutrient ingestion with and without RE. PMID- 27704292 TI - A population-specific correlation between ADIPOQ rs2241766 and rs 1501299 and colorectal cancer risk: a meta-analysis for debate. AB - AIMS: Many epidemiological studies have investigated the correlation between adiponectin, C1Q and collagen domain containing (ADIPOQ) single nucleotide polymorphisms (SNPs) and risk of colorectal cancer (CRC). Although conflicting results have been reported, there was dispute regarding two SNPs (rs2241766 T/G and rs1501299 G/T). Therefore, we conducted a meta-analysis to systematically assess the associations and try to find the reasons for the dispute. METHODS: We searched PubMed, the Cochrane Library, Elsevier, Wiley Online Library, China National Knowledge Infrastructure, WanFang data and Chongqing VIP to search for all eligible case-control studies published up to January 2015. Effect sizes of odds ratios (OR) and 95 % confidence intervals (95 % CI) were calculated using a fixed- or random-effect model. RESULTS: Ten case-control studies including 4377 cases and 5584 controls were selected. A significant difference was observed in Chinese (OR 0.76; 95 % CI 0.68, 0.85; P < 0.001) and Ashkenazi Jewish populations (OR 0.79; 95 % CI 0.63, 0.99; P = 0.04) for rs2241766 with dominant model (TT vs TG + GG). A significant difference was observed in the Chinese population (OR 1.23; 95 % CI 1.11, 1.37; P < 0.001) for rs1501299 with dominant model (TT vs TG + GG). In addition, intake of red meat showed a synergistic effect between ADIPOQ gene and risk of colorectal cancer (CRC). CONCLUSIONS: ADIPOQ SNPs rs2241766 T/G and rs 1501299 G/T have a population-specific correlation with risk of CRC. However, small sample studies may increase reporting bias, particularly if the total number of studies included in the analysis is small. PMID- 27704293 TI - Sensory Responsiveness in Siblings of Children with Autism Spectrum Disorders. AB - This study examined sensory responsiveness in unaffected siblings of children with autism spectrum disorder (ASD) and associations between sensory responsiveness and social severity. Sensory Profile Caregiver Questionnaires and Social Responsiveness Scales were completed by parents of 185 children between age 4 and 10.95 years. Significant differences were found between participants with ASD and controls, and between participants with ASD and unaffected siblings for all sensory quadrants and domains, but not between controls and unaffected siblings. Social responsiveness scores were significantly correlated with scores from most sensory profile categories. Sensory responsiveness as an endophenotype of ASD is not indicated from these findings; however, studies with larger numbers of unaffected siblings and controls are needed to confirm the null hypothesis. PMID- 27704294 TI - Brief Report: Which Came First? Exploring Crossmodal Temporal Order Judgements and Their Relationship with Sensory Reactivity in Autism and Neurotypicals. AB - Previous studies have indicated that visual-auditory temporal acuity is reduced in children with autism spectrum conditions (ASC) in comparison to neurotypicals. In the present study we investigated temporal acuity for all possible bimodal pairings of visual, tactile and auditory information in adults with ASC (n = 18) and a matched control group (n = 18). No group differences in temporal acuity for crossmodal stimuli were observed, suggesting that this may be typical in adults with ASC. However, visual-tactile temporal acuity and bias towards vision when presented with visual-auditory information were both predictors of self-reported sensory reactivity. This suggests that reduced multisensory temporal acuity and/or attention towards vision may contribute to atypical sensory reactivity. PMID- 27704295 TI - Do CAD/CAM dentures really release less monomer than conventional dentures? AB - OBJECTIVES: Computer-aided design (CAD)/computer-aided manufacturing (CAM) dentures are assumed to have more favourable material properties than conventionally fabricated dentures, among them a lower methacrylate monomer release. The aim of this study was to test this hypothesis. MATERIALS AND METHODS: CAD/CAM dentures were generated from ten different master casts by using four different CAD/CAM systems. Conventional, heat-polymerised dentures served as control group. Denture weight and volume were measured; the density was calculated, and the denture surface area was assessed digitally. The monomer release after 7 days of water storage was measured by high-performance liquid chromatography. RESULTS: Whole You Nexteeth and Wieland Digital Dentures had significantly lower mean volume and weight than conventional dentures. Baltic Denture System and Whole You Nexteeth had a significantly increased density. Baltic Denture System had a significantly smaller surface area. None of the CAD/CAM dentures released significantly less monomer than the control group. CONCLUSIONS: All tested dentures released very low amounts of methacrylate monomer, but not significantly less than conventional dentures. A statistically significant difference might nevertheless exist in comparison to other, less recommendable denture base materials, such as the frequently used autopolymerising resins. CLINICAL RELEVANCE: CAD/CAM denture fabrication has numerous advantages. It enables the fabrication of dentures with lower resin volume and lower denture weight. Both could increase the patient comfort. Dentures with higher density might exhibit more favourable mechanical properties. The hypothesis that CAD/CAM dentures release less monomer than conventional dentures could, however, not be verified. PMID- 27704296 TI - Photodynamic therapy decrease immune-inflammatory mediators levels during periodontal maintenance. AB - Antimicrobial photodynamic therapy (aPDT) was introduced as a promising adjuvant therapy on the periodontal treatment. The aim of this study was to evaluate the effect of aPDT on inflammatory mediator levels in residual periodontal pockets of patients with severe chronic periodontitis under periodontal maintenance, during 12 months follow-up. A randomized controlled trial study was conducted in 28 patients with severe chronic periodontitis. After non-surgical periodontal treatment, patients with at least four teeth with residual pocket probing depth (PPD) >=4 mm were randomly assigned to either aPDT or control group. The aPDT (low power laser: 660 nm, 40 mW, 90 J/cm2, methylene blue 0.01 %) was performed at baseline and 3, 6, and 9 months. Clinical parameters were collected before and 3 and 12 months after the intervention, and gingival crevicular fluid was collected in the same times, including 1 week after the intervention. Immunological evaluation was carried out using the Luminex assay which quantified the expression of ten cytokines: interleukin (IL)-1alpha, IL-1beta, IL-8, IL-1ra, fibroblast growth factor (FGF), vascular endothelial growth factor (VEGF), interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha, IL-4, and IL-10. All clinical variables showed significant improvement for both groups, but there was no statistical difference between groups with no clinical benefits. IL-1alpha, IL 1beta, IL-8, and VEGF showed significant differences (p < 0.05) between groups, whereas IL-1ra mediators, IFN-gamma, and IL-10 demonstrated a statistical difference (p < 0.01) over time in the same group. At any time, FGF, IL-4, and TNF-alpha showed no statistical difference between groups (p > 0.05). aPDT therapy can improve the benefits on inflammation control during the periodontal maintenance. PMID- 27704297 TI - A large survey among European trainees in clinical microbiology and infectious disease on training systems and training adequacy: identifying the gaps and suggesting improvements. AB - The purpose of this investigation was to perform a survey among European clinical microbiology (CM) and infectious disease (ID) trainees on training satisfaction, training tools, and competency assessment. An online, anonymous survey in the English language was carried out between April and July 2015. There were 25 questions: seven in a 5-point Likert scale (1: worst scenario, 5: best scenario) and the remainder as closed multiple-choice questions in five areas (satisfaction, adequacy, system, mentorship, and evaluation of training). Included were 419 respondents (215 CM, 159 ID, and 45 combined CM/ID) from 31 European countries [mean age (standard deviation) 32.4 (5.3) years, 65.9 % women]. Regarding satisfaction on the training scheme, CM and ID scored 3.6 (0.9) and 3.2 (1.0), respectively. These scores varied between countries, ranging from 2.5 (1.0) for Italian ID to 4.3 (0.8) for Danish CM trainees. The majority of respondents considered training in management and health economics inadequate and e-learning and continuing medical education programs insufficient. Many trainees (65.3 % of CM and 62.9 % of ID) would like to have more opportunities to spend a part of their training abroad and expected their mentor to be more involved in helping with future career plans (63.5 % of CM and 53.4 % of ID) and practical skills (53.0 % of CM and 61.2 % of ID). Two-thirds of the respondents across the specialties agreed that a European exam should be developed, but half of them thought it should not be made mandatory. This survey shows high heterogeneity in training conditions in European countries, identifies perceived gaps in training, and suggests areas for improvements. PMID- 27704298 TI - Sequential formation of two branched intermediates during protein splicing of class three inteins. AB - Inteins are the protein equivalent of introns. They are seamlessly removed during post-translational maturation of their host protein (extein). Inteins from extremophiles played a key role in understanding intein-mediated protein splicing. There are currently three classes of inteins defined by catalytic mechanism and sequence signatures. This study demonstrates splicing of three class 3 mini-inteins: Burkholderia vietnamiensis G4 Bvi IcmO intein, Mycobacterium smegmatis MC2 155 Msm DnaB-1 intein and Mycobacterium leprae strain TN Mle DnaB intein. B. vietnamiensis has a broad ecological range and remediates trichloroethene. M. smegmatis is a biofilm forming soil bacteria. Although other intein classes have only a single branched intermediate at the C-terminal splice junction, the class 3 intein reaction pathway includes two branched intermediates. The class 3 specific branched intermediate is formed by an internal cysteine, while the C-terminal branch intermediate is at a serine or threonine in all class 3 inteins except the Bvi IcmO intein, where it is a cysteine. This latter cysteine was unable to compensate for mutation of the class 3-specific internal catalytic cysteine despite the Bvi IcmO intein having an N terminal splice junction naturally tuned for a cysteine nucleophile, demonstrating the mandatory order of branch intermediates in class 3 inteins. PMID- 27704299 TI - Child Abuse and Psychiatric Co-morbidity Among Chinese Adolescents: Emotional Processing as Mediator and PTSD from Past Trauma as Moderator. AB - This study investigated whether child abuse was associated with psychiatric co morbidity in a group of Chinese adolescents, and whether this association would be mediated by emotional processing difficulties and moderated by the severity of PTSD from other traumas in the past. Four hundred seventy-four adolescents participated in the study. They completed the Childhood Trauma Questionnaire Short Form, General Health Questionnaire-28, the Posttraumatic Stress Diagnostic Scale, and Emotional processing scale-25. The results showed that after adjusting for the total number of traumatic events and how long ago the most traumatic event occurred, child abuse was associated with psychiatric co-morbidity. This association was not moderated by the severity of PTSD from past traumas but mediated by emotion processing difficulties. To conclude, adolescents who experience child abuse can develop emotional processing difficulties which in turn impact on psychiatric symptoms. Experience of past trauma does not influence these psychological processes. PMID- 27704300 TI - Forward Genetic Screening Using Behavioral Tests in Zebrafish: A Proof of Concept Analysis of Mutants. AB - The zebrafish enjoys several advantages over other model organisms. It is small, easy to maintain, prolific, and numerous genetic tools are available for it. For example, forward genetic screens have allowed investigators to identify important genes potentially involved in a variety of functions from embryogenesis to cancer. However, despite its sophisticated behavioral repertoire, behavioral methods have rarely been utilized in forward genetic screens. Here, we employ a two-tiered strategy, a proof of concept study, to explore the feasibility of behavioral screens. We generated mutant lines using transposon-based insertional mutagenesis, allowing us to bias mutant selection with target genes expressed within the brain. Furthermore, we employed an efficient and fast behavioral pre selection in which we investigated the locomotory response of 5-day post fertilization old larval fish to hyperosmotic shock. Based on this assay, we selected five lines for our lower throughput secondary adult behavioral screen. The latter screen utilized tests in which computer animated image presentation and video-tracking-based automated quantification of behavior allowed us to compare heterozygous zebrafish with their wild-type siblings on their responses to a variety of stimuli. We found significant mutation induced adult behavioral alterations in 4 out of the 5 lines analyzed, including changes in response to social or fear inducing stimuli, to handling and novelty, or in habituation to novelty. We discuss the pros and cons of behavioral phenotyping and of the use of different forward genetic methods in biomedical research with zebrafish. PMID- 27704302 TI - Longitudinal Relationships between Bullying and Moral Disengagement among Adolescents. AB - Moral disengagement is a series of cognitive processes used to disengage moral standards to achieve absolved guilt and permit immoral conduct and has been found to be an important connection to bullying and aggressive behaviors among adolescents. This study examined the longitudinal relationship between moral disengagement and bullying behavior among a group of adolescents from fifth grade to ninth grade (n = 1180, mean age = 12.2, SD = 1.29, 46.5 % female, 80.2 % Caucasian/White, 7.1 % Black/African American, 5.4 % Latino/Hispanic, 2.4 % Asian American, and 1.7 % other) over three semesters. The objectives were to investigate (a) whether moral disengagement was a precursor to bullying behavior, vice versa, or whether the relationship was reciprocal and (b) whether gender and grade predicted moral disengagement and bullying behavior. The results showed that moral disengagement predicted bullying perpetration 6 months later. Also, older students and males utilized more moral disengagement than younger students and females and younger students and males engaged in greater bullying perpetration. Indirect paths linking gender and grade to bullying via moral disengagement at previous time points were identified and implications for bullying prevention are discussed. The findings underscore the importance of examining moral disengagement when studying bullying and across gender and development.

AB - The objective of this study was to examine correlates of human papillomavirus (HPV) vaccine use according to Advisory Committee on Immunization Practices (ACIP)'s recommendations among US adolescent girls. We used National Immunization Survey of Teens 2013 data. Based on provider-verified (n = 9403) information, 57.3, 39.1 and 19.0 % of adolescent girls, initiated, completed and completed the HPV vaccine according to ACIP's recommendation (by age 12), respectively. Hispanic race/ethnicity, a physician recommendation for HPV vaccine and >=1 influenza vaccine in the past 3 years were all associated with a higher likelihood of compliance with ACIP's recommendation. Girls from a larger family and those whose immunization provider was a STD/school/teen clinic were less likely to receive the vaccine at the recommended age compared to a girl raised in a smaller sized family and received immunization from a hospital facility, respectively. Only one-fifth of 13-17 yo girls receive the HPV vaccine by age 12 as recommended by ACIP. Physician visits and influenza vaccination settings are opportunities to improve vaccine series completion at the recommended age. PMID- 27704301 TI - Genetic and Genomic Response to Selection for Food Consumption in Drosophila melanogaster. AB - Food consumption is an essential component of animal fitness; however, excessive food intake in humans increases risk for many diseases. The roles of neuroendocrine feedback loops, food sensing modalities, and physiological state in regulating food intake are well understood, but not the genetic basis underlying variation in food consumption. Here, we applied ten generations of artificial selection for high and low food consumption in replicate populations of Drosophila melanogaster. The phenotypic response to selection was highly asymmetric, with significant responses only for increased food consumption and minimal correlated responses in body mass and composition. We assessed the molecular correlates of selection responses by DNA and RNA sequencing of the selection lines. The high and low selection lines had variants with significantly divergent allele frequencies within or near 2081 genes and 3526 differentially expressed genes in one or both sexes. A total of 519 genes were both genetically divergent and differentially expressed between the divergent selection lines. We performed functional analyses of the effects of RNAi suppression of gene expression and induced mutations for 27 of these candidate genes that have human orthologs and the strongest statistical support, and confirmed that 25 (93 %) affected the mean and/or variance of food consumption.

PMID- 27704305 TI - Health-related quality of life in patients with serious non-specific symptoms undergoing evaluation for possible cancer and their experience during the process: a mixed methods study. AB - PURPOSE: The purpose of this research was to measure changes in HRQoL during the diagnostic evaluation of patients presenting with non-specific symptoms possibly attributable to cancer, to describe their experiences of HRQoL and to merge these findings with intent to obtain a more comprehensive understanding of their HRQoL experience during this stressful life event. METHODS: A convergent mixed methods (MM) design was used and involved quantitative data about HRQoL measured by the EORTC-QLQ-C30 instrument and qualitative interview data about patients' HRQoL experiences. Participants completed the EORTC-QLQ-C30 questionnaire prior to and after evaluation. The baseline questionnaire informed the purposive sampling for the qualitative interview study, and open-end questions matched to the EORTC-QLQ C30 constructs were used in the semi-structured interviews. RESULTS: A total of 838 patients were enrolled in the quantitative study; 680 (81 %) also completed follow-up. Twenty-one patients participated in interviews. The MM findings are the meta-inferences drawn by looking across the matched quantitative and qualitative findings: physical function, social function, role function, emotional function, cognitive function, social function, symptoms and quality of life. CONCLUSION: The survey results illustrate that HRQoL improved over time and the qualitative findings confirmed and further expanded the survey results. The MM analysis underlines that the HRQoL experience cannot be observed independently from context. Participants adapted to their situation over time, and this may change their perceptions of HRQoL. These findings can be used to enhance evidence based care as clinicians need to be aware of how the context influences the HRQoL experience. PMID- 27704307 TI - Association of the Common Catalase Gene Polymorphism rs1001179 With Glycated Hemoglobin and Plasma Lipids in Hyperlipidemic Patients. AB - Catalase represents perhaps the most effective antioxidant defense in the body under conditions of increased oxidative stress, and rs1001179 (CAT-262C >T) is its most extensively studied gene polymorphism. Using an established PCR-RFLP method for genotyping, we examined the association of rs1001179 with glycated hemoglobin (HbA1c) and plasma lipids using univariate analyses with age, sex, body mass index (BMI), smoking, and alcohol abuse as covariates, in a group of dyslipidemic patients from northern Greece. Our results suggest that the TT genotype is a risk factor for increased HbA1c and plasma triglycerides, and that this association is modulated by the BMI and/or age of the patients. PMID- 27704310 TI - Role of Leptin and SOCS3 in Inhibiting the Type I Interferon Response During Obesity. AB - Obesity provokes an imbalance in the immune system, including an aberrant type I interferon response during some viral infections and after TLR stimulation. SOCS3 overexpression and altered systemic leptin levels could be responsible for the reduced type I interferon production in people with obesity and, eventually, significantly increase the risk of viral infection. The aim of this study was to determine whether SOCS3- and leptin-induced tolerance are responsible for the reduced type I interferon production in people with obesity. SOCS3 overexpression in PBMCs from people with obesity was inhibited with the small interfering RNA (siRNA) assay, and leptin-induced tolerance was evaluated in PBMCs from non-obese volunte?ers and U937 cells treated with TLR ligands. SOCS3, but not SOCS1, gene silencing via siRNA increased the type I interferon response in PBMCs obtained from people with obesity. On the other hand, leptin induced SOCS3 expression and inhibited type I interferons in PBMCs from healthy donors and in U937 monocytes stimulated with TLR ligands. Taken together, these results demonstrate that reduced type I interferon production in obesity is caused by SOCS3 overexpression as well as tolerance induced by leptin. Here, we demonstrate a key role of leptin and SOCS3 in inhibiting the type I interferon response during obesity. PMID- 27704308 TI - Toxicants in folk remedies: implications of elevated blood lead in an American born infant due to imported diaper powder. AB - Though most childhood lead exposure in the USA results from ingestion of lead based paint dust, non-paint sources are increasingly implicated. We present interdisciplinary findings from and policy implications of a case of elevated blood lead (13-18 mcg/dL, reference level <5 mcg/dL) in a 9-month-old infant, linked to a non-commercial Malaysian folk diaper powder. Analyses showed the powder contains 62 % lead by weight (primarily lead oxide) and elevated antimony [1000 parts per million (ppm)], arsenic (55 ppm), bismuth (110 ppm), and thallium (31 ppm). These metals are highly bioaccessible in simulated gastric fluids, but only slightly bioaccessible in simulated lung fluids and simulated urine, suggesting that the primary lead exposure routes were ingestion via hand-mouth transmission and ingestion of inhaled dusts cleared from the respiratory tract. Four weeks after discontinuing use of the powder, the infant's venous blood lead level was 8 mcg/dL. Unregulated, imported folk remedies can be a source of toxicant exposure. Additional research on import policy, product regulation, public health surveillance, and culturally sensitive risk communication is needed to develop efficacious risk reduction strategies in the USA. The more widespread use of contaminated folk remedies in the countries from which they originate is a substantial concern. PMID- 27704311 TI - Transcriptome analysis of the gonads of olive flounder (Paralichthys olivaceus). AB - Olive flounder (Paralichthys olivaceus) is an economically important cultured marine fish in China, Korea, and Japan. Controlling and managing the breeding of olive flounder in captivity is an imperative step toward obtaining a sustainable supply of this fish in aquaculture production systems. Therefore, investigation on the molecular regulatory mechanism of gonadal development and gametogenesis in this species is of great significance in aquaculture. Furthermore, identification of the expression profile of numerous sex-related genes is the first step to primarily understand such molecular regulatory mechanism. Six female and six male gonads obtained from 2-year-old olive flounders were sequenced using Illumina, which produced 6.68 and 6.24 GB data for ovary and testis, respectively. The reads were mapped to the draft genome of olive flounder, and then the reads per kilobase per million (FPKM) for each gene were calculated. The female-/male biased expressed genes were investigated based on the FPKM values. Overall, 3086 female-biased and 5048 male-biased genes were screened out. GO enrichment analysis showed that the GO terms "male meiosis," "gamete generation," "fertilization," "spermatogenesis," and "germ plasma" were enriched in male biased genes. In addition, the GO terms "cell morphogenesis involved in differentiation," "embryonic morphogenesis," "plasma membrane," "steroid hormone receptor activity," and "aromatase activity" were enriched in female-biased genes. Moreover, 373,369 single nucleotide polymorphisms and 32,993 indels were identified in the transcriptome. This work is the largest collection of gonad transcriptome data for olive flounder and provides an extensive resource for future gonadal development and gametogenesis molecular biology studies in this species. PMID- 27704312 TI - Prediction of Antiphospholipid syndrome using Annexin A5 competition assay in patients with SLE. AB - A significantly high correlation between reduced activity of Annexin A5 by the flow cytometric assay (FCA) and the diagnosis of antiphospholipid syndrome (APS) has been reported. The aim of this study was to assess the clinical and laboratory significance of the Annexin A5 competition assay among patients with systemic lupus erythematosus (SLE). The FCA competition assay was performed on blood samples from 57 consecutive SLE patients. The FCA was performed according to a previously validated method. Forty-seven patients (82.5 %) had SLE without APS and ten (17.5 %) had SLE with APS. Twenty-four (42 %) of the patients had mean levels of AnxA5 fluorescence below the mean and standard deviation of the controls and were considered positive. SLE patients with a positive FCA were found to have an increased risk for a hypercoagulable or vascular state (86 % of the patients had cerebrovascular disease, 89 % had Raynaud's phenomenon, and 80 % had deep vein thrombosis). The risk for any hypercoagulable or vascular state was significantly increased (P = 0.012, RR-2.3, 95 % CI 1.4-3.8). A positive FCA assay was found in 90 % of the patients with APS (P < 0.001), with a sensitivity of 90 % and a specificity of 68 % for this diagnosis. The positive and negative predictive values were 0.4 and 0.97, respectively. Correlations were found between positive FCA and positive Anti-Cardiolipin antibody (P < 0.001), and Anti beta2 glycoprotein I levels (P = 0.013). Our findings suggest that the FCA is a practical assay for the detection of clinically relevant APS among patients with SLE. PMID- 27704313 TI - The effect of etanercept on traditional metabolic risk factors for cardiovascular disease in patients with rheumatoid arthritis. AB - Patients with rheumatoid arthritis (RA) are at an increased risk of cardiovascular disease (CVD). Treatment with tumor necrosis factor inhibitors improves both joint symptoms associated with RA and also CVD risk. This exploratory analysis of a phase 4 study evaluated changes in metabolic risk factors in patients with RA treated with etanercept. Metabolic analytes were measured at baseline, week 12, and week 24 in patients enrolled in a randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of etanercept in moderately active RA. Patients received either placebo or etanercept 50 mg every week (QW) for 12 weeks, after which all patients received etanercept 50 mg QW through week 24. Levels of metabolic analytes were assessed in all patients, including patients with diabetes and hyperlipidemia, and described descriptively. A total of 210 patients were randomized, 104 to placebo and 106 to etanercept. There were no significant changes in metabolic risk factors from baseline to week 12 or 24 in all patients. Levels of metabolic analytes were similar in patients with diabetes and hyperlipidemia, with some exceptions; fasting glucose and fasting insulin decreased through week 12, and hemoglobin A1C decreased slightly through week 24 in patients with diabetes. Treatment with etanercept did not adversely affect levels of metabolic risk factors for CVD in patients with RA. PMID- 27704314 TI - Ontogenetic Changes in Azoxyglycoside Levels in the Leaves of Dioon edule Lindl. AB - Plants have multiple strategies, including phytochemicals that protect their vulnerable tissues against pathogens and herbivores. Dioon edule, like all cycads, possess unique azoxy-type compounds, azoxyglycosides (AZGs) as a chemical defense; however, the ontogenetic variability of these compounds in this long lived cycad is unknown. Here, we investigated the effects of plant age, sex, genotype and individual heterozygosity on AZG levels in mature leaves of wild D. edule populations from eastern Mexico. Individuals were divided into three ontogenetic stages: seedlings, juveniles and adults. We established overall leaf quality by quantifying pigments associated with photosynthesis; chlorophylla, chlorophyllb and lutein. Leaf chlorophylla levels were higher in seedlings compared to adult cycads. Plants were genotyped using 11 microsatellite markers and foliar AZG levels were quantified by HPLC. AZG levels do not correlate with plant genotype or the individual's heterozygosity. Genetic analysis identified a distinction between lowland and highland individuals; foliar AZG levels were higher in lowland adult cycads compared to highland individuals. In both populations, the highest AZG levels were found in seedlings compared to adult cycads. These young cycads are highly reliant on their few leaves since seedlings bear one or two leaves for the first years of their life and, thus, are unlikely to recover from defoliation. The results suggest that cycad leaves with a greater nutritive content and a higher value for long-term survival are better protected with higher AZG levels. Female adult cycads have higher AZG levels compared to males, suggesting that the benefits of defense could also be linked to reproductive costs. PMID- 27704315 TI - Lessons from the Far End: Caterpillar FRASS-Induced Defenses in Maize, Rice, Cabbage, and Tomato. AB - Plant defenses to insect herbivores have been studied in response to several insect behaviors on plants such as feeding, crawling, and oviposition. However, we have only scratched the surface about how insect feces induce plant defenses. In this study, we measured frass-induced plant defenses in maize, rice, cabbage, and tomato by chewing herbivores such as European corn borer (ECB), fall armyworm (FAW), cabbage looper (CL), and tomato fruit worm (TFW). We observed that caterpillar frass induced plant defenses are specific to each host-herbivore system, and they may induce herbivore or pathogen defense responses in the host plant depending on the composition of the frass deposited on the plant, the plant organ where it is deposited, and the species of insect. This study adds another layer of complexity in plant-insect interactions where analysis of frass-induced defenses has been neglected even in host-herbivore systems where naturally frass accumulates in enclosed feeding sites over extended periods of time. PMID- 27704316 TI - The Involvment of Hematopoietic-Specific PLC -beta2 in Homing and Engraftment of Hematopoietic Stem/Progenitor Cells. AB - Migration and bone marrow (BM) homing of hematopoietic stem progenitor cells (HSPCs) is regulated by several signaling pathways, and here we provide evidence for the involvement in this process of hematopoietic-specific phospholipase C beta2 (PLC-beta2). This enzyme is involved in release of intracellular calcium and activation of protein kinase C (PKC). Recently we reported that PLC-beta2 promotes mobilization of HSPCs from BM into peripheral blood (PB), and this effect is mediated by the involvement of PLC-beta2 in the release of proteolytic enzymes from granulocytes and its role in disintegration of membrane lipid rafts. Here we report that, besides the role of PLC-beta2 in the release of HSPCs from BM niches, PLC-beta2 regulates the migration of HSPCs in response to chemotactic gradients of BM homing factors, including SDF-1, S1P, C1P, and ATP. Specifically, HSPCs from PLC-beta2-KO mice show impaired homing and engraftment in vivo after transplantation into lethally irradiated mice. This decrease in migration of HSPCs can be explained by impaired calcium release in PLC-beta2-KO mice and a high baseline level of heme oxygenase 1 (HO-1), an enzyme that negatively regulates cell migration. PMID- 27704317 TI - The addition of renal sympathetic denervation to pulmonary vein isolation reduces recurrence of paroxysmal atrial fibrillation in chronic kidney disease patients. AB - BACKGROUND: Atrial fibrillation (AF) frequently complicates chronic kidney disease (CKD). AF treatment is challenging and requires complete pulmonary vein isolation (PVI). Recently, renal sympathetic denervation (RSD) has been reported to reduce AF recurrence when performed alongside PVI. METHODS: A prospective therapeutic study of patients with controlled hypertension and paroxysmal AF was undertaken. Renal function was evaluated using estimated glomerular filtration rate. Outcomes for patients with normal renal function who underwent PVI (n = 101) were compared with those for CKD patients who underwent either PVI alone (n = 96) or PVI + RSD (n = 39). The primary endpoint was recurrence of AF recorded by 24-h Holter monitoring. RESULTS: During the 22.4 +/- 12.1 months following intervention, the incidence of AF recurrence was higher in CKD patients treated with PVI alone (61.5 %) than in CKD patients treated with PVI + RSD (38.5 %; HR 1.86, 95 % CI 1.14-3.03, P = 0.0251) or patients without CKD subjected to PVI (35.6 %; hazard ratio (HR) 2.27, 95 % confidence interval (CI) 1.51-3.42, P < 0.0001). In particular, the addition of RSD to PVI significantly reduced AF recurrence in CKD stage 4, but not stage 2 or 3, patients. Ambulatory blood pressure and mean heart rate were not different between groups or time points. No complications of either procedure were observed. CONCLUSIONS: PVI + RSD is a safe treatment that is superior to PVI alone for treatment of paroxysmal AF in CKD patients. PMID- 27704318 TI - What Differences in Morphologic Features of the Knee Exist Among Patients of Various Races? A Systematic Review. AB - BACKGROUND: Most TKA prostheses are designed based on the anatomy of white patients. Individual studies have identified key anthropometric differences between the knees of the white population and other major ethnic groups, yet there is limited understanding of what these findings may indicate if analyzed collectively. QUESTION/PURPOSE: What are the differences in morphologic features of the distal femur and proximal tibia among and within various ethnicities? METHODS: A systematic review of the PubMed database and a hand-search of article bibliographies identified 235 potentially eligible English-language studies. Studies were excluded if they did not include morphology results or had insufficient data for analysis, were unrelated to the distal femur or proximal tibia, were conducted in pediatric patients or those undergoing unicondylar knee arthroplasty, or bone surface measurements were obtained for trauma products. This left 30 eligible studies (9050 knees). Study quality was assessed and reported as good, fair, or poor according to the NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Morphometric data for the distal femur and proximal tibia were available for four ethnic groups: East Asian (23 studies; 5543 knees), white (11 studies; 3111 knees), Indian (three studies; 283 knees), and black (three studies; 113 knees). Although relatively underrepresented, the knees from the Indian and black studies were maintained for hypothesis-generating purposes and to highlight crucial gaps in the data. The two key dimensions for selecting a suitable implant based on a patient's unique anatomy-AP length and mediolateral (ML) width-were assessed for the femur and tibia, in addition to aspect ratio, calculated by dividing the ML width by the AP length. Study measurement techniques were compared visually when possible to ensure that each pooled study conducted a similar measurement process. Any significant measurement outliers were reviewed for eligibility to determine if the measurement techniques and landmarks used were comparable to the other studies included. RESULTS: White patients had larger femoral AP measurements than East Asians (62 mm, [95% CI, 57-66 mm] vs 59 mm, [95% CI, 54-63 mm]; mean difference, 3 mm; p < 0.001), a smaller femoral aspect ratio than East Asians (1.20, [95% CI, 1.11-1.29] vs 1.25, [95% CI, 1.16-1.34]; mean difference, 0.05; p = 0.001), and a larger tibial aspect ratio than black patients (1.55, [95% CI, 1.40-1.71] vs 1.49, [95% CI, 1.33-1.64]; mean difference, 0.06; p = 0.005). CONCLUSIONS: This analysis uncovered differences of size (AP height and ML width of the femur and tibia) and shape (tibial and femoral aspect ratios) among knees from white, East Asian, and black populations. Future research is needed to understand the clinical implications of these discrepancies and to provide additional data with underrepresented groups. PMID- 27704319 TI - Clinical outcomes of acute kidney injury developing outside the hospital in elderly. AB - PURPOSE: Although various studies have improved our knowledge about the clinical features and outcomes of acute kidney injury developing in the hospital (AKI-DI) in elderly subjects, data about acute kidney injury developing outside the hospital (AKI-DO) in elderly patients (age >= 65 years) are still extremely limited. This study was performed to investigate prevalence, clinical outcomes, hospital cost and related factors of AKI-DO in elderly and very elderly patients. METHODS: We conducted a prospective, observational study in patients (aged >= 65 years) who were admitted to our center between May 01, 2012, and May 01, 2013. Subjects with AKI-DO were divided into two groups as "elderly" (group 1, 65-75 years old) and "very elderly" (group 2, >75 years old). Control group (group 3) consisted of the hospitalized patients aged 65 years and older with normal serum creatinine level. In-hospital outcomes and 6-month outcomes were recorded. Rehospitalization rate within 6 months of discharge was noted. Hospital costs and mortality rates of each group were investigated. Risk factors for AKI-DO were determined. RESULTS: The incidence of AKI-DO that required hospitalization in elderly and very elderly patients was 5.8 % (136/2324) and 11 % (100/905), respectively (p < 0.001), with an overall incidence of 7.3 % (236/3229). Chronic kidney disease (CKD) was developed in 43.4 % of group 1 and 67 % of group 2 within the 6 months of discharge (p < 0.001). Progression to CKD was significantly lower in the control group than in groups 1 and 2 (p < 0.001). Mortality rates for groups 1, 2 and 3 were 23.5 % (n = 32), 31 % (n = 31) and 4.2 % (n = 8), respectively (p < 0.05). Rehospitalization rate within the 6 months of discharge for the groups with AKI-DO was higher than for the control group (p < 0.001). Hospital cost of groups 1 and 2 was significantly higher than that of the control group (p < 0.001). Nonsteroidal anti-inflammatory drugs (NSAIDs) (OR: 6.839, 95 % CI = 4.392-10.648), angiotensin-converting enzyme inhibitors (ACEI) (OR: 7.846, 95 % CI = 5.161-11.928), angiotensin receptor blockers (ARB) (OR: 6.466, 95 % CI = 4.813-8.917), radiocontrast agents (OR: 8.850, 95 % CI = 5.857 13.372), hypertension (OR: 4.244, 95 % CI = 2.729-6.600), diabetes mellitus (OR: 2.303, 95 % CI = 1.411-3.761), heart failure (OR: 3.647, 95 % CI = 2.276-5.844) and presence of infection (OR: 3.149, 95 % CI = 1.696-5.845) were found as the risk factors for AKI-DO in elderly patients (p < 0.001 for all). Patients with AKI-DO had higher 6-month mortality rate (HR 1.721, 95 % CI: 1.451-2.043, p < 0.001). Mortality risk increased 0.519 times at 20th day. CONCLUSIONS: The incidence of AKI-DO requiring hospitalization is higher in very elderly patients than elderly ones, especially in male gender. Use of ACEI, ARB, NSAID and radiocontrast agents is the main risk factors for the development of AKI-DO in the elderly. PMID- 27704320 TI - Association between serum gamma-glutamyltransferase and chronic kidney disease in urban Han Chinese: a prospective cohort study. AB - PURPOSE: Limited numbers of literatures have focused on the association between gamma-glutamyltransferase (GGT) and chronic kidney disease (CKD), and their results were controversial. Therefore, in this study, we set up a large-scale cohort of Chinese population to discover and verify the association between serum GGT and CKD. METHODS: Our cohort study was based on 21,818 patients who visited Health Management Center of Shandong Provincial Hospital, China, to receive routine health check-up during the period of 2005-2010, and we used multivariate Cox regression model to clarify whether elevated serum GGT increased the risk of CKD or not. RESULTS: During the follow-up of 57,891 person-years, 1456 patients developed CKD, giving rise to an incidence density of 25.15 per 1000 person-years (1456/57,891 person-years). After adjusting gender, age, baseline serum creatinine (SCr), body mass index (BMI), serum albumin (ALB), alanine aminotransferase (ALT), hemoglobin, white blood cell count (WBC), triglyceride (TG), total cholesterol (TC), hypertension, cardiovascular disease (CVD), diabetes, smoking and drinking status, the risk for CKD increased with the elevated serum GGT quartiles. The hazard ratio (HR) for CKD was 1.326 (95 % confidence interval (CI), 1.073-1.639) when the top quartile of serum GGT was compared with the bottom one, and the HR of log-transformed serum GGT for CKD was 1.658 (95 % CI, 1.294-2.125). The results were consistent in males but different in females when gender was stratified. CONCLUSION: The result reveals that there is a positive relationship between increasing serum GGT levels and the incidence of CKD which suggests that elevated GGT level could be a potential indicator for risk of CKD. PMID- 27704321 TI - Preoperative [99mTc]MIBI SPECT/CT Interpretation Criteria for Localization of Parathyroid Adenomas-Correlation with Surgical Findings. AB - PURPOSE: Minimally invasive surgery for parathyroid adenomas (PTA) requires precise identification and localization of the diseased gland prior to exploration for optimal surgical planning. The Perrier classification allows for accurate, reproducible, and reliable description of PTA location and communication of clinically significant information to surgeons. The current study compares the Perrier localization of PTA on [99mTc]methoxyisobutylisonitrile ([99mTc]MIBI) single-photon emission computed tomography (SPECT)/X-ray computed tomography (CT) with the results of surgery. PROCEDURES: Eighty-eight patients (60 females), age 13-82 years, with primary hyperparathyroidism underwent [99mTc]MIBI SPECT/CT prior to surgery. Eight patients had parathyroid hyperplasia and underwent excision of 3.5 parathyroid glands, including five patients with a negative [99mTc]MIBI study and three patients with multiple foci of uptake, and were excluded from further analysis. Each PTA was localized to Perrier levels A-G. The surgeon located each PTA found on surgery using the same classification. PTA localization on SPECT/CT and at surgery was compared. RESULTS: Eighty patients with surgically confirmed PTA were analyzed. On [99mTc]MIBI SPECT/CT, 63 patients had a single and one patient had two PTAs for a total of 65 PTAs. At surgery, 85 PTAs were resected in 80 patients, including 75 patients with single and 5 with two PTAs. Twenty PTAs found on surgery were not detected on [99mTc]MIBI. The relatively lower weight of these 20 PTAs is probably the main reason for the false-negative results group. The same Perrier localization was determined on SPECT/CT and surgery in 52/65 PTAs (80 %). In the 13 incongruent cases, the PTAs were localized at different locations but on the same side of the thyroid gland. CONCLUSIONS: [99mTc]MIBI SPECT/CT accurately localized a PTA according to the Perrier classification in 80 % of cases. Reporting SPECT/CT results using anatomy-based PTA localization criteria accepted by surgeons can contribute significantly towards better interspecialty communication and will improve performance of minimally invasive surgical removal of PTAs. PMID- 27704322 TI - An agent-based simulation model of patient choice of health care providers in accountable care organizations. AB - Accountable care organizations (ACO) in the United States show promise in controlling health care costs while preserving patients' choice of providers. Understanding the effects of patient choice is critical in novel payment and delivery models like ACO that depend on continuity of care and accountability. The financial, utilization, and behavioral implications associated with a patient's decision to forego local health care providers for more distant ones to access higher quality care remain unknown. To study this question, we used an agent-based simulation model of a health care market composed of providers able to form ACO serving patients and embedded it in a conditional logit decision model to examine patients capable of choosing their care providers. This simulation focuses on Medicare beneficiaries and their congestive heart failure (CHF) outcomes. We place the patient agents in an ACO delivery system model in which provider agents decide if they remain in an ACO and perform a quality improving CHF disease management intervention. Illustrative results show that allowing patients to choose their providers reduces the yearly payment per CHF patient by $320, reduces mortality rates by 0.12 percentage points and hospitalization rates by 0.44 percentage points, and marginally increases provider participation in ACO. This study demonstrates a model capable of quantifying the effects of patient choice in a theoretical ACO system and provides a potential tool for policymakers to understand implications of patient choice and assess potential policy controls.

AB - According to American College of Emergency Physicians, emergency department (ED) crowding occurs when the identified need for emergency services exceeds available resources for patient care in the ED, hospital, or both. ED crowding is a widely reported problem and several crowding scores are proposed to quantify crowding using hospital and patient data as inputs for assisting healthcare professionals in anticipating imminent crowding problems. Using data from a large academic hospital in North Carolina, we evaluate three crowding scores, namely, EDWIN, NEDOCS, and READI by assessing strengths and weaknesses of each score, particularly their predictive power. We perform these evaluations by first building a discrete-event simulation model of the ED, validating the results of the simulation model against observations at the ED under consideration, and utilizing the model results to investigate each of the three ED crowding scores under normal operating conditions and under two simulated outbreak scenarios in the ED. We conclude that, for this hospital, both EDWIN and NEDOCS prove to be helpful measures of current ED crowdedness, and both scores demonstrate the ability to anticipate impending crowdedness. Utilizing both EDWIN and NEDOCS scores in combination with the threshold values proposed in this work could provide a real-time alert for clinicians to anticipate impending crowding, which could lead to better preparation and eventually better patient care outcomes.

AB - Children with intestinal failure have had improved survival, particularly those with extreme short bowel syndrome, over the last 10-15 y. This has been attributed to better understanding of the pathophysiology of intestinal failure, improvement in line care, recognition of the importance of a team approach as well as the progress of intestinal transplant as a viable option. Parenteral nutrition remains the cornerstone for the continual survival of these patients. This review will cover contemporary approaches to intestinal failure including post surgical approaches, non-transplant surgery, dietetic and medication approaches during the adaptation process, considerations for home parenteral nutrition and latest in intestinal transplantation.

AB - The Familias Unidas intervention is an efficacious family-based preventive intervention for reducing substance use and other health risks among Hispanic youth. A current randomized controlled trial (RCT) is examining this intervention's efficacy when delivered via the Internet (eHealth). eHealth interventions can overcome logistical barriers to participation, yet there is limited information about the feasibility of these interventions, especially among ethnic minorities. This paper examines participation and predictors of participation in the eHealth Familias Unidas intervention in a sample of 113 Hispanic families whose adolescent had behavioral problems. Analyses examined multidimensional ways of characterizing participation, including the following: (1) total intervention participation, (2) initial engagement (participating in at least one of the first three intervention sessions), (3) completing the pre recorded, eHealth parent group sessions, and (4) participating in the live, facilitator-led, eHealth family sessions. Participation in this eHealth intervention was comparable to, and in most cases higher than, previous, face-to face Familias Unidas interventions. High levels of baseline family stress were associated with lower initial engagement and lower family session participation. Greater parental Hispanicism was associated with more participation in eHealth parent group sessions and across the total intervention. Higher levels of baseline effective parenting, in other words less intervention need, were significantly associated with lower levels of total intervention participation and lower levels of family session participation. Implications for preventive interventions delivered via Internet are discussed. PMID- 27704327 TI - Obstructive sleep apnea (OSA) and clinical depression-prevalence in a sleep center. AB - BACKGROUND: This study aimed to determine the prevalence of clinical depression as defined by ICD-10 criteria in all patients with obstructive sleep apnea (OSA) referred to a sleep center. METHODS: Prospective general and sleep evaluations were conducted in 447 consecutive patients referred to our sleep center during the first quarter of 2008. Inclusion criteria were Apnea Hypopnea Index (AHI) > 9, completion of the Beck Depression Inventory (BDI-II) with a score >=14 and World Health Organization WHO-5 Well-Being Index (WHO-5) <= 13. The subsequent psychiatric examination according to ICD-10 criteria was performed by in-house clinical sleep specialists. RESULTS: A total of 447 patients were surveyed, of whom 322 had an AHI > 9. Out of these, 85 met the combined screening criterion BDI II >= 14 and WHO-5 <= 13. Eighty-one patients underwent a psychiatric examination by psychiatric sleep specialists. In 21.5 % of the sample, clinical depression was diagnosed. Other complaints existed in 12 % (n = 10); 7 % (n = 6) of patients had a different psychiatric diagnosis. CONCLUSIONS: The prevalence of clinical depression according to ICD-10 criteria in a selected clinical sample (referred to the sleep center) was 21.5 %. Mood scales tend to overestimate complaints as compared to psychiatric consultation. Interdisciplinary cooperation is recommended for both OSA patients with symptoms of depression and depressed patients with treatment resistance. PMID- 27704328 TI - Impact of gender and sleep position on relationships between anthropometric parameters and obstructive sleep apnea syndrome. AB - OBJECTIVE: Considering the mechanisms by which obesity affects obstructive sleep apnea syndrome (OSAS) and the differences of fat distribution depending on gender, associations between anthropometric parameters, and OSAS may differ depending on gender or sleep position. We analyzed the impact of gender and sleep position on the relationship between fat distribution and development of OSAS. METHODS: One thousand thirty-two consecutive subjects were analyzed. Recorded anthropometric measurements and overnight polysomnographic data of the subjects were reviewed retrospectively. The presence of OSAS was defined by the respiratory disturbance index (RDI) >=5 with documented symptoms of excessive daytime sleepiness. RESULTS: Eight hundred fifty-eight males and 174 females were included. Male subjects had significantly higher body mass index (BMI), larger waist circumference (WC), and lower percent of overall body fat (P < 0.0001, P < 0.0001, and P < 0.0001, respectively). The severity of OSAS was significantly higher in male subjects (RDI 26.9 +/- 22.4 in males vs. 10.2 +/- 13.8 in females, P < 0.0001). In male subjects, BMI, WC, and overall body fat were significantly associated with severity of OSAS and had larger impacts on supine RDI than lateral RDI. Overall body fat was not associated with severity of OSAS in female subjects, and there were no significant differences of the associations between all anthropometric parameters and RDIs depending on sleep position. CONCLUSIONS: Evaluation of the correlation of anthropometric data with severity of OSAS should consider sleep position as well as gender. PMID- 27704329 TI - Impact of Population Recruitment on the HIV Epidemics and the Effectiveness of HIV Prevention Interventions. AB - Mechanistic mathematical models are increasingly used to evaluate the effectiveness of different interventions for HIV prevention and to inform public health decisions. By focusing exclusively on the impact of the interventions, the importance of the demographic processes in these studies is often underestimated. In this paper, we use simple deterministic models to assess the effectiveness of pre-exposure prophylaxis in reducing the HIV transmission and to explore the influence of the recruitment mechanisms on the epidemic and effectiveness projections. We employ three commonly used formulas that correspond to constant, proportional and logistic recruitment and compare the dynamical properties of the resulting models. Our analysis exposes substantial differences in the transient and asymptotic behavior of the models which result in 47 % variation in population size and more than 6 percentage points variation in HIV prevalence over 40 years between models using different recruitment mechanisms. We outline the strong influence of recruitment assumptions on the impact of HIV prevention interventions and conclude that detailed demographic data should be used to inform the integration of recruitment processes in the models before HIV prevention is considered. PMID- 27704330 TI - Day-to-Day Population Movement and the Management of Dengue Epidemics. AB - Dengue is a growing public health problem in tropical and subtropical cities. It is transmitted by mosquitoes, and the main strategy for epidemic prevention and control is insecticide fumigation. Effective management is, however, proving elusive. People's day-to-day movement about the city is believed to be an important factor in the epidemiological dynamics. We use a simple model to examine the fundamental roles of broad demographic and spatial structures in epidemic initiation, growth and control. We show that the key factors are local dilution, characterised by the vector-host ratio, and spatial connectivity, characterised by the extent of habitually variable movement patterns. Epidemic risk in the population is driven by the demographic groups that frequent the areas with the highest vector-host ratio, even if they only spend some of their time there. Synchronisation of epidemic trajectories in different demographic groups is governed by the vector-host ratios to which they are exposed and the strength of connectivity. Strategies for epidemic prevention and management may be made more effective if they take into account the fluctuating landscape of transmission intensity associated with spatial heterogeneity in the vector-host ratio and people's day-to-day movement patterns. PMID- 27704332 TI - A cost-utility analysis of dabigatran, enoxaparin, and usual care for venous thromboprophylaxis after hip or knee replacement surgery in Thailand. AB - To analyze the cost-utility of oral dabigatran etexilate, enoxaparin sodium injection, and no intervention for venous thromboembolism (VTE) prophylaxis after total hip or knee replacement (THR/TKR) surgery among Thai patients. A cost utility analysis using a decision tree model was conducted using societal and healthcare payers' perspectives to simulate relevant costs and health outcomes covering a 3-month time horizon. Costs were adjusted to year 2014. The willingness-to-pay threshold of THB 160,000 (USD 4926) was used. One-way sensitivity and probabilistic sensitivity analyses using a Monte Carlo simulation were performed. Compared with no VTE prophylaxis, dabigatran and enoxaparin after THR and TKR surgery incurred higher costs and increased quality adjusted life years (QALYs). However, their incremental cost-effectiveness ratios were high above the willingness to pay. Compared with enoxaparin, dabigatran for THR/TKR lowered VTE complications but increased bleeding cases; dabigatran was cost saving by reducing the costs [by THB 3809.96 (USD 117.30) for THR] and producing more QALYs gained (by 0.00013 for THR). Dabigatran (vs. enoxaparin) had a 98 % likelihood of being cost effective. Dabigatran is cost-saving compared to enoxaparin for VTE prophylaxis after THR or TKR under the Thai context. However, both medications are not cost-effective compared to no thromboprophylaxis. PMID- 27704331 TI - Admixing of MPTP-Resistant and Susceptible Mice Strains Augments Nigrostriatal Neuronal Correlates to Resist MPTP-Induced Neurodegeneration. AB - Disease genetics in admixed populations like Hispanic-Americans, African Americans, etc. are gaining importance due to high disease burden in them. Furthermore, epidemiological studies conclusively prove ethnicity-based differential prevalence of Parkinson's disease (PD), since the American Caucasians are more susceptible than Asian-Indians and Africans. Contradictorily, Anglo-Indians, an admixture of Europeans and Asian-Indians are five-times less susceptible than Indians. We evaluated the neural basis of this phenomenon using the cytomorphological features of susceptibility to nigrostriatal neurotoxin 1 methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). The nigral dopaminergic neuronal numbers, their size and tyrosine hydroxylase (TH), PitX3 and Nurr1 expression were compared in MPTP-susceptible C57BL/6J mice, MPTP-resistant CD-1 mice and their crossbreds using stereology, morphometry and densitometry. Apoptotic index was evaluated by TUNEL-assay and caspase-3 expression. Striatal volume, TH and glial derived neurotrophic factor (GDNF) expression were studied. The normal CD-1 and crossbreds had significantly more, although smaller, nigral dopaminergic neurons than C57BL/6J, and a larger striatum. The crossbreds had higher TH, Nurr1 and PitX3 levels. MPTP administration caused loss of ~50-60 % nigral dopaminergic neurons in C57BL/6J and ~15 % in CD-1, but none in crossbreds. MPTP-induced cellular shrinkage in C57BL/6J was contrasted by nuclear enlargement without somal alterations in resistant strains. MPTP lowered the striatal TH and GDNF in C57BL/6J. Elevated striatal GDNF in CD-1 and crossbreds could be of compensatory nature and complemented the reduced nigral caspase-3 expression to attenuate and/or block apoptosis. Similar neural correlates of resilience are envisaged in the Anglo-Indian population. Thus, we present the core neuroanatomical features of resilience against PD and evidence for ethnicity based differential prevalence. PMID- 27704333 TI - Risk of intracranial hemorrhage associated with therapeutic anticoagulation for venous thromboembolism in cancer patients: a systematic review and meta-analysis. AB - Intracranial hemorrhage (ICH) in cancer patients can result from tumor bleeding and from antitumor and anticoagulation therapy. The effect of anticoagulation on the incidence of ICH in cancer patients has not been quantified. Our objective was to determine the risk of intracranial hemorrhage associated with anticoagulation therapy for cancer-associated venous thromboembolism (VTE). Systematic review and meta-analysis of studies assessing the safety of anticoagulation therapy in patients with cancer-associated VTE. The primary endpoint of interest was the incidence of ICH and secondary outcomes included all major bleeding, and the time to ICH and major bleeding. After identifying 595 studies, five studies and 2089 patients were included in the analyses. We found that the relative risk (RR) for ICH was 0.494, 95 % CI (0.105-2.331) when low molecular weight heparin (LMWH) with vitamin K antagonist (VKA) anticoagulants were compared. No statistically significant differences in risk were measured. The risk of major bleeding using any type of anticoagulation therapy in patients with cancer-associated VTE was RR 0.853, 95 % CI (0.549, 1.327). After meta analytic review of data published through August 2015, we conclude that therapeutic anticoagulation with LMWH given <=6 months does not increase the risk of ICH in cancer patients compared to VKA. The risk of ICH in cancer patients is also similar to that of non-cancer patients. Available data were insufficient to determine if the ICH risk increase changes when the duration of anticoagulation is >6 months.

AB - Two new furofuran lignans were isolated from the stems of Acanthopanax senticosus, along with seven known compounds. Their structures were all determined by spectroscopic analyses and chemical methods. All the isolates were evaluated for in vitro inhibitory activity against DGAT1 and DGAT2. Compounds 1 and 2 were found to exhibit selective inhibitory activity on DGAT1 with IC50 values 89.5 +/- 1.5 and 57.5 +/- 1.3 uM, respectively. PMID- 27704335 TI - Aristoyunnolin H attenuates extracellular matrix secretion in cardiac fibroblasts by inhibiting calcium influx. AB - Aristoyunnolin H is a novel aristophyllene sesquiterpenoid isolated from the traditional Chinese medicine Aristolochia yunnanensis Franch. The present research was designed to explore the anti-fibrotic effects of aristoyunnolin H in adult rat cardiac fibroblasts (CFs) stimulated with angiotensin II (Ang II). Western blot analysis data showed that aristoyunnolin H reduced the upregulation of fibronectin (FN), connective tissue growth factor and collagen I(Col I) production induced by Ang II in CFs. By studying the dynamic intracellular changes of Ca2+, we further found that while aristoyunnolin H relieved the calcium influx, it has no effect on intracellular calcium store release. Meanwhile, aristoyunnolin H also inhibited the Ang II-stimulated phosphorylation of Ca2+/calmodulin-dependent protein kinase II. In conclusion, aristoyunnolin H may attenuate extracellular matrix secretion in vitro by inhibiting Ang II induced calcium signaling. PMID- 27704336 TI - Cytotoxicity of lipid-soluble ginseng extracts is attenuated by plasma membrane redox enzyme NQO1 through maintaining redox homeostasis and delaying apoptosis in human neuroblastoma cells. AB - Lipid-soluble ginseng extracts (LSGE) is known to inhibit many types of cancer cells through arresting cell cycle and inducing apoptosis. Usually, normal cells are can also be damaged by anti-tumor reagents. The plasma membrane redox system (PMRS) is enhanced to compensate mitochondrial dysfunction and impaired energy metabolism. NADH-quinone oxidoreductase 1 (NQO1), a plasma membrane redox enzyme, is known to be induced by panaxytriol, one of components of lipid-soluble ginseng extracts (LSGE). The objective of this study was determine the mechanisms of NQO1 involved in neuroprotection in response to cytotoxicity induced by LSGE. Exposure of control SH-SY5Y cells to LSGE resulted in dramatic loss of cell viability in a dose-dependent manner. The loss of cell viability was significantly recovered in cells transfected with NQO1. LSGE-induced cell death occurred through apoptosis such as cell shrinkage, chromatin condensation and cleavage of poly (ADP-ribose) polymerase. These apoptotic features were significantly attenuated by overexpression of NQO1. Levels of oxidative/nitrative damage were highly elevated by LSGE in a dose-dependent manner. However, these elevated levels were greatly reduced by overexpression of NQO1. In addition, overexpression of NQO1 attenuated the decrease in mitochondrial complex I activity caused by LSGE. Taken together, these findings suggest that overexpressed NQO1 can protect cells against LSGE induced cytotoxicity through lowering oxidative/nitrative damage and delaying apoptosis, supporting that stimulation of NQO1 activity could be a therapeutic targets in neurodegeration. PMID- 27704337 TI - Modeling the differentiation of A- and C-type baroreceptor firing patterns. AB - The baroreceptor neurons serve as the primary transducers of blood pressure for the autonomic nervous system and are thus critical in enabling the body to respond effectively to changes in blood pressure. These neurons can be separated into two types (A and C) based on the myelination of their axons and their distinct firing patterns elicited in response to specific pressure stimuli. This study has developed a comprehensive model of the afferent baroreceptor discharge built on physiological knowledge of arterial wall mechanics, firing rate responses to controlled pressure stimuli, and ion channel dynamics within the baroreceptor neurons. With this model, we were able to predict firing rates observed in previously published experiments in both A- and C-type neurons. These results were obtained by adjusting model parameters determining the maximal ion channel conductances. The observed variation in the model parameters are hypothesized to correspond to physiological differences between A- and C-type neurons. In agreement with published experimental observations, our simulations suggest that a twofold lower potassium conductance in C-type neurons is responsible for the observed sustained basal firing, where as a tenfold higher mechanosensitive conductance is responsible for the greater firing rate observed in A-type neurons. A better understanding of the difference between the two neuron types can potentially be used to gain more insight about pathophysiology and treatment of diseases related to baroreflex function, e.g. in patients with autonomic failure, a syndrome that is difficult to diagnose in terms of its pathophysiology.

PMID- 27704339 TI - Conversion of Vertical Sleeve Gastrectomy to a Functional Single-Anastomosis Gastric Bypass: Technique and Preliminary Results Using a Non-Adjustable Ring Instead of Stapled Division. AB - BACKGROUND: Recent data show that some patients will have insufficient weight loss or experience weight regain after sleeve gastrectomy. Dilation of the sleeve over time or use of an inadequate technique may contribute to relapse of morbid obesity. Repeat sleeve gastrectomy is the most obvious option but requires stapling of scarred tissue, has a higher risk of leakage, and is prone to re enlargement with time. We herein describe a simple and innovative technique with which to revise vertical sleeve gastrectomy (VSG) into functional single anastomosis gastric bypass (f-SAGB). MATERIALS AND METHODS: Twelve VSGs were converted to f-SAGB by placing a GaBP Ring (Bariatec Corp., Palos Verdes Peninsula, CA, USA) at the base of the "sleeve" and performing the anastomosis above the ring. The length of the biliopancreatic loop was chosen according to the volume of the pouch and the patient's residual eating capability. RESULTS: All procedures were completed by laparoscopy and were uneventful. The average decrease in the body mass index was from 41.0 to 29.5 kg/m2 at the 12-month follow-up. No ring-related complications were reported. CONCLUSION: f-SAGB is a low-risk and effective option with which to revise VSG in patients with inadequate weight loss. Avoiding detachment of the pouch from the antrum assures full reversibility of the procedure and preserves the chance to explore the remnant stomach and biliary tree. PMID- 27704340 TI - Evaluation of individual cognitive remediation therapy (CRT) for the treatment of young people with anorexia nervosa. AB - PURPOSE: Research suggests that there are cognitive inefficiencies underlying Anorexia Nervosa (AN), with CRT showing promise in improving these inefficiencies in adults. This area has yet to be explored in a younger population. The aim of this study was to evaluate the use of CRT for young people. METHODS: A within subjects design was used to compare the performance of children and adolescents with AN on several neuropsychological measures administered before and after a course of CRT. RESULTS: Ninety-two female participants diagnosed with AN aged between 11 and 17 (M = 14.8, SD = 1.6), all receiving treatment at a specialist inpatient unit. The assessment consisted of the Rey-Osterrieth Complex Figure test (ROCFT), the Behaviour Rating Inventory of Executive Function-Self-Report (BRIEF-SR), and the D-KEFS Colour-Word Interference Test (CWT). Repeated-measures t tests were used to analyse the ROCFT and BRIEF-SR data. There was a significant improvement in Central Coherence Index (p < .001), Immediate Recall (p < .001), Shift (p < .001) Cognitive Shift (p = 002), Behavioural shift (p < .001), Emotional Control (p < .001), Working Memory (p = .001), Plan/Organize (p < .001), Monitor (p = .001) BRI (p < .001), MI (p = .001), and GEC (p < .001). On the D-KEFS CWT, a repeated-measure Wilcoxon signed-rank test revealed a significant improvement in Error Rate (p = .019) and a repeated-measures t test revealed a significant improvement in time taken (p < .001). CONCLUSIONS: Results suggest that CRT for children and adolescents with AN could strengthen specific cognitive domains. PMID- 27704341 TI - Shame proneness and eating disorders: a comparison between clinical and non clinical samples. AB - PURPOSE: To explore the relationship between shame proneness, eating disorders outcomes and psychological aspects of patients with eating disorders (ED). METHODS: Sixty-six girls applying for inpatient treatment for ED and 110 female undergraduate students were assessed using the Eating Disorder Inventory-3 and the Shame Proneness Scale of the Test of Self-Conscious Affect. RESULTS: Shame proneness showed significant correlations with several ED components and psychological scales of EDI-3, with some variations across the subgroups. Shame proneness levels were significantly higher in the clinical group than in controls. CONCLUSIONS: Shame proneness can be an important component for the development and the maintenance of ED due to a strong correlation not only with ED symptoms but also with psychological aspects of this disease, in both clinical and non-clinical samples.

The method for obtaining sufficient amount of activated lymphocytes can be recommended for adoptive cell immunotherapy of cancer patients. PMID- 27704342 TI - Sustaining Work Participation Across the Life Course. AB - Introduction Many disability prevention strategies are focused on acute injuries and brief illness episodes, but there will be growing challenges for employers to manage circumstances of recurrent, chronic, or fluctuating symptoms in an aging workforce. The goal of this article is to summarize existing peer-review research in this area, compare this with employer discourse in the grey literature, and recommend future research priorities. Methods The authors participated in a year long sponsored collaboration that ultimately led to an invited 3-day conference, "Improving Research of Employer Practices to Prevent Disability", held October 14 16, 2015, in Hopkinton, Massachusetts, USA. The collaboration included a topical review of the scientific and industry literature, group discussion to identify key areas and challenges, drafting of initial documents, and feedback from peer researchers and a special panel of experts with employer experience. Results Cancer and mental illness were chosen as examples of chronic or recurring conditions that might challenge conventional workplace return-to-work practices. Workplace problems identified in the literature included fatigue, emotional exhaustion, poor supervisor and co-worker support, stigma, discrimination, and difficulties finding appropriate accommodations. Workplace intervention research is generally lacking, but there is preliminary support for improving workplace self-management strategies, collaborative problem-solving, and providing checklists and other tools for job accommodation, ideas echoed in the literature directed toward employers. Research might be improved by following workers from an earlier stage of developing workplace concerns. Conclusions Future research of work disability should focus on earlier identification of at-risk workers with chronic conditions, the use of more innovative and flexible accommodation strategies matched to specific functional losses, stronger integration of the workplace into on-going rehabilitation efforts, and a better understanding of stigma and other social factors at work. PMID- 27704343 TI - New Business Structures Creating Organizational Opportunities and Challenges for Work Disability Prevention. AB - Purpose Flexible work arrangements are growing in order to develop resource efficient production and because of advanced technologies, new societal values, changing demographics, and globalization. The article aims to illustrate the emerging challenges and opportunities for work disability prevention efforts among workers in alternate work arrangements. Methods The authors participated in a year-long collaboration that ultimately led to an invited 3-day conference, "Improving Research of Employer Practices to Prevent Disability," held October 14 16, 2015, in Hopkinton, Massachusetts, USA. The collaboration included a topical review of the literature, group conference calls to identify key areas and challenges, drafting of initial documents, review of industry publications, and a conference presentation that included feedback from peer researchers and a roundtable discussion with experts having direct employer experience. Results Both worker and employer perspectives were considered, and four common alternate work arrangements were identified: (a) temporary and contingent employment; (b) small workplaces; (c) virtual work/telework; and (d) lone workers. There was sparse available research of return-to-work (RTW) and workplace disability management strategies with regard to alternate work patterns. Limited research findings and a review of the grey literature suggested that regulations and guidelines concerning disabled workers are often ambiguous, leading to unsatisfactory protection. At the workplace level, there was a lack of research evidence on how flexible work arrangements could be handled or leveraged to support RTW and prevent disability. Potential negative consequences of this lack of organizational guidance and information are higher costs for employers and insurers and feelings of job insecurity, lack of social support and integration, or work intensification for disabled workers. Conclusions Future studies of RTW and workplace disability prevention strategies should be designed to reflect the multiple work patterns that currently exist across many working populations, and in particular, flexible work arrangements should be explored in more detail as a possible mechanism for preventing disability. Labor laws and policies need to be developed to fit flexible work arrangements.

AB - Transcription activity of NF-kappaB in sensory neurons was analyzed in vitro using classical immunocytochemical methods and transgenic technologies. Activation of NF-kappaB in NIH3T3 cells and in murine sensory neurons after in vitro stimulation with TNF-alpha was demonstrated by the immunocytochemical method; however, the expression of the reporter NF-kappaB/LacZ transgene was detected only after addition of histon deacetylase inhibitor. Hence, formally contradictory conclusions from the results of immunocytochemical analysis and reporter transgene expression were in line with the hypothesis on epigenetic repression of NF-kappaB activity in sensory neurons mediated by histon deacetylases.

AB - Titanium and polypropylene mesh endoprostheses were implanted into the rat abdominal cavity and the populations of cells migrating to their surface were analyzed. On both materials, the cells were presented mainly by macrophages that proliferated, activated, and fused to form multinuclear cells. Contact with the foreign surface triggered superoxide anion generation and myeloperoxidase synthesis by macrophages (these processes were more intense on polypropylene implants than on titanium ones) and stimulated production of nitric oxide by macrophage. It was hypothesized that the effects of free nitrogen and oxygen radicals lead to oxidation and destruction of the polypropylene endoprosthesis surface. PMID- 27704348 TI - Effect of Hyperlipidemia and Plasma Cytokine Levels in Rats after Anterior Abdominal Wall Reconstruction with the Use of Synthetic Endoprostheses. AB - The effect of hyperlipidemia on the systemic production of cytokines was evaluated in the plasma of rats after anterior abdominal wall reconstruction with polypropylene (Esfil) and polytetrafluorethylene (Ecoflon) endoprostheses. The reference group was formed from animals without hyperlipidemia, in which anterior abdominal wall plasty was carried out with the use of the same endoprostheses. Intact rats without hyperlipidemia and intervention served as the control. Hypercytokinemia was detected on days 1-10 after reconstructive surgery on the anterior abdominal wall. Polytetrafluoroethylene alloplasty was associated with higher plasma production of pro- and anti-inflammatory cytokines, which characterized mainly the implant reactogenicity. Hyperlipidemia modified the reactivity of immunocompetent cells to the endoprosthesis. A progressive decrease in the content of proinflammatory cytokines (IL-1beta and TNF-alpha) was observed by day 10 after endoprosthesis implantation, this decrease being more manifest in response to polytetrafluoroethylene. High plasma levels of pro- and antiinflammatory cytokines (IL-1beta, INF-alpha, IFN-gamma, and IL-10) were detected in hyperlipidemic rats on day 1 after polypropylene plasty; by day 10, the plasma level of IFN-gamma increased, which reflected positive activation of Th1 lymphocytes.

AB - Total RNA from the bone marrow of healthy donor rats was injected to experimental rats 6 h, 2 h, or 30 min prior to a single gamma-irradiation in the sublethal dose of 6 Gy. Injection total RNA 30 min prior to the exposure most effectively restored erythropoiesis in experimental animals. In 5 days, reticulocyte count in these animals 30-fold surpassed the control (injection of 0.9% NaCl). In 12 days, the content of new erythroblastic islands in the bone marrow in rats injected with the total RNA 2 h or 30 min prior to irradiation increased significantly and erythropoiesis recovery activation was observed. PMID- 27704350 TI - Magnetic Resonance Imaging of Brain Involvement in Dogs Using Paramagnetic Contrast Enhancement with Mn(II)-DCTA P. AB - Experimental study of a new paramagnetic complex Mn-DCTA is carried out. The complex (0.5 M manganese(II) solution with trans-1,2-diamine cyclohexane N,N,N',N'-tetraacetic acid; Cyclomang) was used for contrast magnetic resonance imaging visualization of CNS involvement in dogs with severe forms of Babesia canis infection. CNS injuries were visualized in all cases, with highly intense contrasting at the expense of Mn-DCTA accumulation at the periphery of the damaged zone. Quantitative evaluation of the paramagnetic accumulation in the focus showed that the amplification index wa s 1.19+/-0.11 for the central areas and 1.47+/-0.17 for the peripheral ones. The pituitary (1.18+/-0.05) and vascular plexuses of the lateral ventricles (1.12+/-0.09) were also contrasted. Injection of the paramagnetic to dogs was not associated with any kinds of pathological or physiological reactions. Mn-DCTA complex allowed contrast visualization of the focal injuries to the CNS and could be regarded as a paramagnetic contrast agent for magnetic resonance imaging of brain injuries in dogs.

AB - We analyzed associations between single nucleotide polymorphisms (SNP) rs13155212 and rs7704267 in the AGGF1 gene (angiogenic factor with G patch and FHA domains 1) and the risk of risk of varicose veins of the legs in ethnic Russians. Frequencies of alleles, genotypes, and haplotypes were estimated in the sample of patients with this disease (474 patients) and in the control group of participants (478 volunteers) without a history of chronic venous disease. None of the studied polymorphisms was associated with the risk of this pathology. The whole AGGF1 gene sequence lies in a single block of high linkage disequilibrium, and both studied polymorphic variants are representative of all other SNP within this region. From these results, a conclusion was made that AGGF1 gene polymorphism does not affect the risk of varicose veins of the legs in ethnic Russians, or its contribution is low and can be revealed only after analysis of larger cohorts.

AB - We synthesized a fluorescence conjugate and modified magnetite-gold nanoparticles carrying prostate specific membrane antigen (PSMA) as the ligand. Analysis of their binding to human prostate cancer cell lines PC-3 (PSMA-) and LNCaP (PSMA+) showed selective interaction of the synthesized conjugate and modified nanoparticles with LNCaP cells. These findings suggest that these nanoparticles can be used in tissue-specific magnetic-resonance imaging. PMID- 27704353 TI - Effect of Potassium Comenate on CNS Functional Status in Rodents Exposed to Combined Hypoxia and Hypercapnia in Comparison with Normally Ventilated Animals. AB - The effects of potassium comenate on functional state of CNS in mice and rats were studied in the open-field and hole-board tests under control conditions and after acute exposure to hypoxia-hypercapnia. The effects of potassium comenate on CNS were also studied in rodents subjected to propofol-induced sleep. Preliminary administration of 4 mg/kg potassium comenate for 3 days attenuated the posthypoxic changes in behavioral reactions (emotional anxiety/reactivity). The pronounced stress-protective effect of potassium comenate was observed both on days 1 and 14 after exposure to hypoxia-hypercapnia. Under normal conditions, potassium comenate moderated behavioral reactions and augmented somniferous effect of propofol. We hypothesized that the antihypoxic effect of potassium comenate is determined by its stress-protective and sedative potencies.

AB - For the development of methods of additional differential diagnostics of gliomas of various grades of malignancy and gliomas and local inflammatory processes in the CNS we studied the intensity of aggregation of peripheral blood cells under the influence of channel blockers ketamine and verapamil. In in vitro experiments, verapamil and ketamine in various dilutions (from 10 to 100,000 times) were added to blood samples and the effects of these dilutions on the intensity of blood aggregation in patients with gliomas of different degree of malignancy, traumatic brain injuries, and other types of neurosurgical pathologies were studied. A correlation was revealed between the decrease in surface charge of blood cells and the type of neurosurgical pathology. The use of functional properties of potential-dependent inotropic NMDA receptors and calcium channels allowed indirect estimation of their activity via parameters of blood cell aggregation induced by channel blockers ketamine and verapamil. PMID- 27704355 TI - Serum Heat Shock Protein 70, as a Potential Biomarker for Small Cell Lung Cancer. AB - The 70 kDa heat shock protein (Hsp70) is a highly conservative molecular chaperone, that has important role in cell integrity. Recently considerable amount of data are accumulating on the potential role of Hsp70 in carcinogenesis and tumor progression. Most papers are focusing on intracellular or membrane bound protein, however very limited data exist on serum Hsp70, that can also induce innate and adaptive immune response. Previously we have published data on the correlation between coloretal cancer progression and serum Hsp70 concentration. The objective of this study was to compare the serum Hsp70 level in patients with small cell lung cancer (SCLC n = 70) and age matched healthy controlls (n = 121) and correlate Hsp70 level with other known serum biomarkers (LDH and NSE) of the disease. We found that the serum level of Hsp70 was significantly higher in SCLC patients compared to control subjects (mean value 6.91 vs 2.47 ng/ml, p = 0.001). The highest Hsp70 concentration was measured in stage IV advanced SCLC (Stage IV versus Stage I-III disease: 9.91 vs 4.38 ng/ml, p = 0.003). The serum Hsp70 level correlated with serum LDH (r = 0.426, p < 0,001) and NSE level (r = 0.455, p < 0,001). We found that high serum Hsp70 level predicted unfavorable survival, risk of death within 1 year was more than 3 times higher in patients with high baseline Hsp70 level (HR:3.509, CI: 1.066-11.562; p = 0.039). Our observations indicate that serum Hsp70 could be a valuable diagnostic and prognostic marker in small cell lung cancer. PMID- 27704356 TI - MicroRNA-27b exerts an oncogenic function by targeting Fbxw7 in human hepatocellular carcinoma. AB - Aberrant expression of microRNAs (miRNAs) plays fundamental effect on the pathogenesis of hepatocellular carcinoma (HCC). MiR-27b was previously found to play important roles in human cancers. However, its expression status, clinical significance, and biological functions in HCC remain largely unclear. The expression status of miR-27b in HCC specimens and cells were determined with qRT PCR. MTT, 5-bromodeoxyuridine (BrdU) proliferation assays, and flow cytometry analysis were carried out to assay proliferation, cell cycle, and apoptosis. A subcutaneous model was used to evaluated the HCC tumor growth in vivo. The putative target gene of miR-27b was disclosed by TargetScan and a luciferase reporter assay. The levels of miR-27b were overexpressed in HCC. Overexpression of miR-27b was correlated with adverse prognostic features and reduced survival rate. Inhibition of miR-27b in SMMC-7721 cells remarkably suppressed proliferative ability and cell-cycle progression while enhanced apoptosis. In contrast, miR-27b overexpression resulted in prominent increased proliferation and process of cell cycle and reduced apoptosis of Hep3B cells. In vivo studies showed that knockdown of miR-27b inhibited the in vivo growth of SMMC-7721 cells in mouse xenograft model. Furthermore, we confirmed that Fbxw7 was directly regulated by miR-27b and mediated the roles of miR-27b in HCC. We suggest that miR-27b serves as an oncogenic miRNA in HCC by modulating proliferation, cell cycle progression, and apoptosis, and its oncogenic effect is mediated by its downstream target gene, Fbxw7. PMID- 27704357 TI - Analysis of expression and prognostic significance of vimentin and the response to temozolomide in glioma patients. AB - Gliomas are the most common primary intracranial malignant tumors in adults. Surgical resection followed by optional radiotherapy and chemotherapy is the current standard therapy for glioma patients. Vimentin, a protein of intermediate filament family, could maintain the cellular integrity and participate in several cell signal pathways to modulate the motility and invasion of cancer cells. The purpose of the present research was to identify the relationship between vimentin expression and clinical characteristics and detect the prognostic and predictive ability of vimentin in patients with glioma. To determine the expression of vimentin in glioma tissues, paraffin-embedded blocks from glioma patients by surgical resection were obtained and evaluated by immunohistochemistry. To further investigate the association of vimentin expression with survival, we employed mRNA expression of vimentin genes from the Chinese Glioma Genome Atlas (CGGA) and the GSE 16011 dataset. Kaplan-Meier analysis and Cox regression model were used to statistical analysis. We detected positive vimentin straining in 84 % of high-grade compared to 47 % in low-grade glioma patients. Additionally, vimentin mRNA expression was correlated with glioma grade in both CGGA and GSE16011 dataset. Patients with low vimentin expression have longer survival than high expression. In multivariate analysis, vimentin was an independent significant prognostic factor for high-grade glioma patients. We also identified that glioblastoma patients with low vimentin expression had a better response to temozolomide therapy. Vimentin expression has a significant association with tumor grade and overall survival of high-grade glioma patients. Low vimentin expression may benefit from temozolomide therapy. PMID- 27704358 TI - A humanized chimeric antibody Hai178 targeted to the beta subunit of F1F0 ATP synthase. AB - Inhibition of tumor vasculature is an effective strategy for cancer therapy. Angiostatin could suppress tumor growth and metastasis by binding and inhibiting F1F0 ATP synthase on the endothelial cell surface. We previously screened a monoclonal antibody (McAb, McAb178-5G10), which specifically bound to ATPase on the surface of cells and showed an angiostatin-like activity. Here, we further generated a panel of CHO-mAb subclone stable expressing a humanized chimeric antibody from hybridoma cell McAb178-5G10 by gene engineer. And then, we successfully expressed the humanized antibody Hai178 at high level in a 5-L wave bioreactor. The vitro results showed that Hai178 retained the specific binding and antitumor activity of murine antibody. Furthermore, Hai178 also had a tumor therapeutic effect in tumor xenografts. These results paved the way for Hai178 as a therapeutic antibody in clinic. PMID- 27704360 TI - E2F-1 promotes DAPK2-induced anti-tumor immunity of gastric cancer cells by targeting miR-34a. AB - Activation of the transcription factor E2F-1 gene is a negative event in dendritic cell (DC) maturation process. Down-regulation of E2F1 causes immaturity of DC thereby stopping antigen production which in turn leads to inhibition of immune responses. E2F-1-free stimulates the NF-kB signaling pathway, leading to activation of monocytes and several other transcription factor genes. In the study, we report that down-regulation of E2F-1 in DCs promote anti-tumor immune response in gastric cancer (GC) cells through a novel mechanism. DCs were isolated from peripheral blood mononuclear cells. E2F-1 small interfering RNA (E2F-1-shRNA) induced down-regulation of E2F-1 mRNA and protein expression in DCs. Furthermore, we identified the E2F-1-shRNA targeted the CD80, CD83, CD86, and MHC II molecules, promoted their expression, and induced T lymphocytes proliferation activity and up-regulation of IFN-I3 production and GC cell killing effect, which significantly correlated with the cytotoxic T lymphocytes activated by E2F-1-shRNA DCs. The higher expression of miR-34a was found which was significantly correlated with the DC enhancing anti-tumor immunity against gastric cancer cell, and miR-34a potently targeted DAPK2 and Sp1, both of which were involved in the deactivation of E2F-1. Moreover, in E2F-1-DC-down-regulation in mice, GC transplantation tumors displayed down-regulation of Sp1, DAPK2, Caspase3, and Caspase7 and progressed to anti-tumor immunity. Collectively, our data uncover an E2F-1-mediated mechanism for the control of DC anti-tumor immunity via miR-34a-dependent down-regulation of E2F-1 expression and suggest its contribution to GC immunotherapy. PMID- 27704359 TI - Transcriptomic characterization of differential gene expression in oral squamous cell carcinoma: a meta-analysis of publicly available microarray data sets. AB - Oral squamous cell carcinoma (OSCC) is a highly prevalent cancer worldwide, and OSCC often goes undiagnosed until advanced disease is present, which contributes to a low survival rate for OSCC patients. The identification of biomarkers for the early detection OSCC and novel therapeutic targets for OSCC treatment is an important research objective. We performed bioinformatics analyses of the gene expression profile of OSCC using microarray data to identify genes that contribute to the development of OSCC. We also predicted the transcription factors involved in the regulation of differential gene expression in OSCC. Our results showed that PI3K, EGFR, STAT1, and CPBP are important contributors to the changes in cellular physiology that occur during the development of OSCC. Therefore, these genes represent potential diagnostic biomarkers and therapeutic targets for OSCC. PMID- 27704362 TI - Isolation and Culture of Adult Intestinal, Gastric, and Liver Organoids for Cre recombinase-Mediated Gene Deletion. AB - The discovery of Lgr5 as a marker of adult stem cells meant that stem cell populations could be purified and studied in isolation. Importantly, when cultured under the appropriate conditions these stem cells form organoids in tissue culture that retain many features of the tissue of origin. The organoid cultures are accessible to genetic and biochemical manipulation, bridging the gap between in vivo mouse models and conventional tissue culture. Here we describe robust protocols to establish organoids from gastrointestinal tissues (stomach, intestine, liver) and Cre-recombinase mediated gene manipulation in vitro. PMID- 27704361 TI - Association of single-nucleotide polymorphisms of high-mobility group box 1 with susceptibility and clinicopathological characteristics of uterine cervical neoplasia in Taiwanese women. AB - To date, no study associated the genetic polymorphisms of high-mobility group box 1 protein (HMGB1) with the development of uterine cervical cancer. We therefore conducted this study to investigate the associations of HMGB1 single-nucleotide polymorphisms (SNPs) with cervical carcinogenesis and clinicopathological characteristics of cancer patients. Five hundred two women, including 112 with invasive cancer, 85 with precancerous lesions of the uterine cervix, and 305 normal controls, were consecutively enrolled into this study. Analysis of HMGB1 SNPs was done by real-time polymerase chain reaction and genotyping. Our results found that the risk of susceptibility to cervical invasive cancer was 1.85 (95 % CI 1.12-3.04; p = 0.016) in women with TC and 1.99 (95 % CI 1.24-3.23; p = 0.005) in women with TC/CC after adjusting for age, using TT as a comparison reference in HMGB1 SNP rs1412125. In rs2249825, the increased risk was also seen for the development of cervical invasive cancer in women with CG [adjusted odds ratio (AOR) 2.04, 95 % CI 1.22-3.40; p = 0.006] or CG/GG (AOR 2.02, 95 % CI 1.22-3.32; p = 0.006) using CC as a comparison reference. An additional integrated in silico analysis confirmed that rs2249825 creates a binding site for v-Myb, which may affect HMGB1 expression. In conclusion, Taiwanese women with TC or TC/CC in HMGB1 SNP rs1412125 as well as CG or CG/GG in rs2249825 were susceptible to the development of cervical invasive cancer. PMID- 27704363 TI - Backbone 1H, 15N, and 13C resonance assignments of the Tom1 VHS domain. AB - Efficient trafficking of ubiquitinated receptors (cargo) to endosomes requires the recruitment of adaptor proteins that exhibit ubiquitin-binding domains for recognition and transport. Tom1 is an adaptor protein that not only associates with ubiquitinated cargo but also represents a phosphoinositide effector during specific bacterial infections. This phosphoinositide-binding property is associated with its N-terminal Vps27, Hrs, STAM (VHS) domain. Despite its biological relevance, there are no resonance assignments of Tom1 VHS available that can fully characterize its molecular interactions. Here, we report the nearly complete 1H, 15N, and 13C backbone resonance assignments of the VHS domain of human Tom1. PMID- 27704364 TI - Peer Review at JGIM.

AB - We assembled a cross-cutting team of experts representing primary care physicians (PCPs), home care physicians, physicians who see patients in skilled nursing facilities (SNF physicians), skilled nursing facility medical directors, human factors engineers, transitional care researchers, geriatricians, internists, family practitioners, and three major organizations: AMDA, SGIM, and AGS. This work was sponsored through a grant from the Association of Subspecialty Physicians (ASP). Members of the team mapped the process of discharging patients from a skilled nursing facility into the community and subsequent care of their outpatient PCP. Four areas of process improvement were identified, building on the prior work of the AMDA Transitions of Care Committee and the experiences of the team members. The team identified issues and developed best practices perceived as feasible for SNF physician and PCP practices to accomplish. The goal of these consensus-based recommended best practices is to provide a safe and high quality transition for patients moving between the care of their SNF physician and PCP. PMID- 27704368 TI - Development and Implementation of a Novel HIV Primary Care Track for Internal Medicine Residents. AB - BACKGROUND: Declining mortality has led to a rising number of persons living with HIV (PLWH) and concerns about a future shortage of HIV practitioners. AIM: To develop an HIV Primary Care Track for internal medicine residents. SETTING: Academic hospital and community health center with a history of caring for PLWH and lesbian, gay, bisexual, and transgender (LGBT) patients. PARTICIPANTS: Internal medicine residents. PROGRAM DESCRIPTION: We enrolled four residents annually in a 3-year track with the goal of having each provide continuity care to at least 20 PLWH. The curriculum included small group learning sessions, outpatient electives, a global health opportunity, and the development of a scholarly project. PROGRAM EVALUATION: All residents successfully accrued 20 or more PLWH as continuity patients. Senior residents passed the American Academy of HIV Medicine certification exam, and 75 % of graduates took positions in primary care involving PLWH. Clinical performance of residents in HIV care quality measures was comparable to those reported in published cohorts. DISCUSSION: We developed and implemented a novel track to train medical residents in the care of PLWH and LGBT patients. Our results suggest that a designated residency track can serve as a model for training the next generation of HIV practitioners. PMID- 27704369 TI - Development of Metabolic Syndrome Associated to Cancer Therapy: Review. AB - Long-term childhood cancer survivors are at great risk of developing late adverse effects after treatment, such as, reduced growth, obesity, decreased fertility, high blood pressure, cardiovascular diseases, impaired glucose, another form of cancer, among others organ dysfunctions, some of them are part of the metabolic syndrome. Metabolic syndrome and cancer connection is still not entirely understood, but there are some notions about it. Metabolic alterations produced during childhood cancer are more likely determined by treatments like radiotherapy, chemotherapy, glucocorticoids therapy, and surgery. Cancer treatment is associated to vascular alterations, hormone deficiencies, changes in insulin sensitivity, lipid metabolism, and inflammatory mediators. Obesity has been considered a crucial component in metabolic syndrome; obesity risk factors during childhood cancer include cranial radiation, female gender, and exposure to glucocorticoids such as dexamethasone. In addition, local radiotherapy or surgery may cause endocrine deficiencies, depends on the directly damage of endocrine organs. Patients who received some types of cancer treatment should be evaluated periodically to early diagnostic metabolic disorders associated to antineoplastic therapy. PMID- 27704371 TI - Esophageal Cancer Surgery for Patients with Concomitant Liver Cirrhosis: A Single Center Matched-Cohort Study. AB - BACKGROUND: Cirrhosis is a risk factor with nonhepatic surgery, but only three series regarding esophagectomy are reported. The Model for End-Stage Liver Disease (MELD) score has shown benefit in risk evaluation, but there is no experience regarding esophagectomy. This study aimed to compare the outcomes of surgery for esophageal cancer between cirrhotic and noncirrhotic patients and to evaluate whether the MELD score has a prognostic value for risk stratification. METHODS: From the authors' esophageal cancer database, they selected all the patients with concomitant cirrhosis who underwent surgery with curative intent and a matched cohort of patients without cirrhosis. The preoperative data included demographics, medical history, blood work, American Society of Anesthesiologists (ASA) score, Child-Turcotte-Pugh (CTP) score, and MELD score. The operative data included type of surgery, radicality, operative time, and blood loss. The postoperative data included hemoderivatives, 90-day morbidity and mortality rates, lab works, and hospital length of stay. The cirrhotic patients were further divided and analyzed according to a MELD score cutoff of 9. RESULTS: Of 3445 esophageal cancer patients, 73 cirrhotic patients underwent surgery. Their 90-day morbidity and mortality rates were higher than those for 146 noncirrhotic patients. The cirrhotic patients also had more respiratory events (p = 0.013) and infections (p = 0.005). The anastomotic complications among the cirrhotic patients were significantly more severe (p = 0.046). No difference in 5 year survival rates was registered. Stratification according to the MELD score showed that patients with a MELD score higher than 9 had a significantly worse postoperative course (5-year survival: p = 0.004). The patients with a MELD score of 9 or lower showed an outcome similar to that of the noncirrhotic patients. CONCLUSIONS: Liver cirrhosis is not an absolute contraindication to esophagectomy. The MELD score can be applicable for esophagectomy risk assessment for cirrhotic patients. PMID- 27704372 TI - Active Surveillance for DCIS: The Importance of Selection Criteria and Monitoring. PMID- 27704370 TI - Clinical Utility of the 12-Gene DCIS Score Assay: Impact on Radiotherapy Recommendations for Patients with Ductal Carcinoma In Situ. AB - OBJECTIVE: The aim of this study was to determine the impact of the results of the 12-gene DCIS Score assay on (i) radiotherapy recommendations for patients with pure ductal carcinoma in situ (DCIS) following breast-conserving surgery (BCS), and (ii) patient decisional conflict and state anxiety. METHODS: Thirteen sites across the US enrolled patients (March 2014-August 2015) with pure DCIS undergoing BCS. Prospectively collected data included clinicopathologic factors, physician estimates of local recurrence risk, DCIS Score results, and pre-/post assay radiotherapy recommendations for each patient made by a surgeon and a radiation oncologist. Patients completed pre-/post-assay decisional conflict scale and state-trait anxiety inventory instruments. RESULTS: The analysis cohort included 127 patients: median age 60 years, 80 % postmenopausal, median size 8 mm (39 % <=5 mm), 70 % grade 1/2, 88 % estrogen receptor-positive, 75 % progesterone receptor-positive, 54 % with comedo necrosis, and 18 % multifocal. Sixty-six percent of patients had low DCIS Score results, 20 % had intermediate DCIS Score results, and 14 % had high DCIS Score results; the median result was 21 (range 0 84). Pre-assay, surgeons and radiation oncologists recommended radiotherapy for 70.9 and 72.4 % of patients, respectively. Post-assay, 26.4 % of overall recommendations changed, including 30.7 and 22.0 % of recommendations by surgeons and radiation oncologists, respectively. Among patients with confirmed completed questionnaires (n = 32), decision conflict (p = 0.004) and state anxiety (p = 0.042) decreased significantly from pre- to post-assay. CONCLUSIONS: Individualized risk estimates from the DCIS Score assay provide valuable information to physicians and patients. Post-assay, in response to DCIS Score results, surgeons changed treatment recommendations more often than radiation oncologists. Further investigation is needed to better understand how such treatment changes may affect clinical outcomes. PMID- 27704373 TI - Simulation of Deformation and Aggregation of Two Red Blood Cells in a Stenosed Microvessel by Dissipative Particle Dynamics. AB - The motion of two red blood cells in a stenosed microvessel was simulated using dissipative particle dynamics. The effects of intercellular interaction, red blood cell deformability and the initial cell orientation on the deformation and aggregation of the RBCs and on the flow resistance were investigated. The red blood cell membrane was treated as a three-dimensional coarse-grained network model and the intercellular interaction was modeled by the Morse potential based on a depletion-mediated assumption. It is shown that the flow resistance increases dramatically when the red blood cells enter into the stenosis and decreases rapidly as RBCs move away from the stenosis. Particularly, for a pair of stiffer red blood cells with the initial inclination angle of 90 degrees , the maximum value of the flow resistance is larger; while a higher flow resistance can also come from a stronger aggregation. For a pair of stiffer red blood cells moving parallel to the main flow, when their positions are closer to the vessel wall at the upstream of the stenosis, the flow resistance increases due to the migration to the vessel center at the stenosis. In addition, for a pair of red blood cells with the initial inclination angle of 0 degrees , the flow resistance from the aggregate formed by a pair of red blood cells with a larger deformation is higher. PMID- 27704374 TI - Biocompatible nano-gallium/hydroxyapatite nanocomposite with antimicrobial activity. AB - Intensive research in the area of medical nanotechnology, especially to cope with the bacterial resistance against conventional antibiotics, has shown strong antimicrobial action of metallic and metal-oxide nanomaterials towards a wide variety of bacteria. However, the important remaining problem is that nanomaterials with highest antibacterial activity generally express also a high level of cytotoxicity for mammalian cells. Here we present gallium nanoparticles as a new solution to this problem. We developed a nanocomposite from bioactive hydroxyapatite nanorods (84 wt %) and antibacterial nanospheres of elemental gallium (16 wt %) with mode diameter of 22 +/- 11 nm. In direct comparison, such nanocomposite with gallium nanoparticles exhibited better antibacterial properties against Pseudomonas aeruginosa and lower in-vitro cytotoxicity for human lung fibroblasts IMR-90 and mouse fibroblasts L929 (efficient antibacterial action and low toxicity from 0.1 to 1 g/L) than the nanocomposite of hydroxyapatite and silver nanoparticles (efficient antibacterial action and low toxicity from 0.2 to 0.25 g/L). This is the first report of a biomaterial composite with gallium nanoparticles. The observed strong antibacterial properties and low cytotoxicity make the investigated material promising for the prevention of implantation-induced infections that are frequently caused by P. aeruginosa. PMID- 27704375 TI - Enhancement of mechanical properties of 3D printed hydroxyapatite by combined low and high molecular weight polycaprolactone sequential infiltration. AB - A new infiltration technique using a combination of low and high molecular weight polycaprolactone (PCL) in sequence was developed as a mean to improve the mechanical properties of three dimensional printed hydroxyapatite (HA). It was observed that using either high (M n~80,000) or low (M n~10,000) molecular weight infiltration could only increase the flexural modulus compared to non-infiltrated HA, but did not affect strength, strain at break and energy at break. In contrast, a combination of low and high molecular infiltration in sequence increased the flexural modulus, strength and energy at break compared to those of non-infiltrated HA or infiltrated by high or low molecular weight PCL alone. This overall enhancement was found to be attributed to the densification of low molecular weight PCL and the reinforcement of high molecular PCL concurrently. The combined low and high molecular weight infiltration in sequence also maintained high osteoblast proliferation and differentiation of the composites at the similar level of the HA. Densification was a dominant mechanism for the change in modulus with porosity and density of the infiltrated HA/PCL composites. However, both densification and the reinforcing performance of the infiltration phase were crucial for strength and toughening enhancement of the composites possibly by the defect healing and stress shielding mechanisms. The sequence of using low molecular weight infiltration and followed by high molecular infiltration was seen to provide the greatest flexural properties and highest cells proliferation and differentiation capabilities. PMID- 27704376 TI - Synthesis of Ag doped calcium phosphate particles and their antibacterial effect as additives in dental glass ionomer cements. AB - Developing dental restorations with enhanced antibacterial properties has been a constant quest for materials scientists. The aim of this study was to synthesize silver doped calcium phosphate particles and use them to improve antibacterial properties of conventional glass ionomer cement. The Ag doped monetite (Ag-DCPA) and hydroxyapatite (Ag-HA) were synthesized by precipitation method and characterized using X-ray diffraction, scanning electron microscope and X-ray fluorescence spectroscopy. The antibacterial properties of the cements aged for 1 day and 7 days were evaluated by direct contact measurement using staphylococcus epidermis Xen 43. Ion concentrations (F- and Ag+) and pH were measured to correlate to the results of the antibacterial study. The compressive strength of the cements was evaluated with a crosshead speed of 1 mm/min. The glass ionomer cements containing silver doped hydroxyapatite or monetite showed improved antibacterial properties. Addition of silver doped hydroxyapatite or monetite did not change the pH and ion release of F-. Concentration of Ag+ was under the detection limit (0.001 mg/L) for all samples. Silver doped hydroxyapatite or monetite had no effect on the compressive strength of glass ionomer cement. PMID- 27704377 TI - Development of a protocol to optimize electric power consumption and life cycle environmental impacts for operation of wastewater treatment plant. AB - In wastewater treatment plants (WWTPs), the portion of operating costs related to electric power consumption is increasing. If the electric power consumption decreased, however, it would be difficult to comply with the effluent water quality requirements. A protocol was proposed to minimize the environmental impacts as well as to optimize the electric power consumption under the conditions needed to meet the effluent water quality standards in this study. This protocol was comprised of six phases of procedure and was tested using operating data from S-WWTP to prove its applicability. The 11 major operating variables were categorized into three groups using principal component analysis and K-mean cluster analysis. Life cycle assessment (LCA) was conducted for each group to deduce the optimal operating conditions for each operating state. Then, employing mathematical modeling, six improvement plans to reduce electric power consumption were deduced. The electric power consumptions for suggested plans were estimated using an artificial neural network. This was followed by a second round of LCA conducted on the plans. As a result, a set of optimized improvement plans were derived for each group that were able to optimize the electric power consumption and life cycle environmental impact, at the same time. Based on these test results, the WWTP operating management protocol presented in this study is deemed able to suggest optimal operating conditions under which power consumption can be optimized with minimal life cycle environmental impact, while allowing the plant to meet water quality requirements. PMID- 27704378 TI - Columnar aerosol characteristics and radiative forcing over the Doon Valley in the Shivalik range of northwestern Himalayas. AB - Spectral aerosol optical depth (AOD) measurements obtained from multi-wavelength radiometer under cloudless conditions over Doon Valley, in the foothills of the western Himalayas, are analysed during the period January 2007 to December 2012. High AOD values of 0.46 +/- 0.08 and 0.52 +/- 0.1 at 500 nm, along with low values of Angstrom exponent (0.49 +/- 0.01 and 0.44 +/- 0.03) during spring (March-May) and summer (June-August), respectively, suggest a flat AOD spectrum indicative of coarse-mode aerosol abundance compared with winter (December February) and autumn (September-November), which are mostly dominated by fine aerosols from urban/industrial emissions and biomass burning. The columnar size distributions (CSD) retrieved from the King's inversion of spectral AOD exhibit bimodal size patterns during spring and autumn, while combinations of the power law and unimodal distributions better simulate the retrieved CSDs during winter and summer. High values of extinction coefficient near the surface (~0.8-1.0 km-1 at 532 nm) and a steep decreasing gradient above are observed via CALIPSO profiles in autumn and winter, while spring and summer exhibit elevated aerosol layers between ~1.5 and 3.5 km due to the presence of dust. The particle depolarisation ratio shows a slight increasing trend with altitude, with higher values in spring and summer indicative of non-spherical particles of dust origin. The aerosol-climate implications are evaluated via the aerosol radiative forcing (ARF), which is estimated via the synergy of OPAC and SBDART models. On the monthly basis, the ARF values range from ~ -30 to -90 W m-2 at the surface, while aerosols cause an overall cooling effect at the top of atmosphere (approx. -5 to 15 W m-2). The atmospheric heating via aerosol absorption results in heating rates of 1.2-1.6 K day-1 during March-June, which may contribute to changes in monsoon circulation over northern India and the Himalayas. PMID- 27704379 TI - Photocatalytic degradation of methylene blue dye by zinc oxide nanoparticles obtained from precipitation and sol-gel methods. AB - Zinc oxide (ZnO) nanoparticles were synthesized by precipitation and sol-gel methods. The aim of this study was to understand how different synthetic methods can affect the photocatalytic activity of ZnO nanoparticles. As-synthesized ZnO nanoparticles were characterized by X-ray diffraction (XRD) and UV-Visible spectroscopic techniques. XRD patterns of ZnO powders synthesized by precipitation and sol-gel methods revealed their hexagonal wurtzite structure with crystallite sizes of 30 and 28 nm, respectively. Their photocatalytic activities were evaluated by photocatalytic degradation of methylene blue, a common water pollutant, under UV radiation. The effects of operational parameters such as photocatalyst load and initial concentration of the dye on photocatalytic degradation of methylene blue were investigated. While the degradation of dye decreased over the studied dye concentration range of 20 to 100 mg/L, an optimum photocatalyst load of 250 mg/L was needed to achieve dye degradation as high as 81 and 92.5 % for ZnO prepared by precipitation and sol-gel methods, respectively. Assuming pseudo first-order reaction kinetics, this corresponded to rate constants of 8.4 * 10-3 and 12.4 * 10-3 min-1, respectively. Hence, sol-gel method is preferred over precipitation method in order to achieve higher photocatalytic activity of ZnO nanostructures. Photocatalytic activity is further augmented by better choice of capping ligand for colloidal stabilization, starch being more effective than polyethylene glycol (PEG).

We recently isolated a consortium, composed of an Arthrobacter sp. strain C1 and an Achromobacter sp. strain C2, that was able to convert iprodione to 3,5 dichloroaniline (3,5-DCA). However, the formation of metabolic intermediates and the role of the strains on iprodione metabolism remain unknown. We examined the degradation of iprodione and its suspected metabolic intermediates, 3,5 dichlorophenyl-carboxamide (metabolite I) and 3,5-dichlorophenylurea-acetate (metabolite II), by strains C1 and C2 and their combination under selective (MSM) and nutrient-rich conditions (LB). Bacterial growth during degradation of the tested compounds was determined by qPCR. Strain C1 rapidly degraded iprodione (DT50 = 2.3 h) and metabolite II (DT50 = 2.9 h) in MSM suggesting utilization of isopropylamine, transiently formed by hydrolysis of iprodione, and glycine liberated during hydrolysis of metabolite II, as C and N sources. In contrast, strain C1 degraded metabolite I only in LB and growth kinetics suggested the involvement of a detoxification process. Strain C2 was able to transform iprodione and its metabolites only in LB. Strain C1 degraded vinclozolin, a structural analog of iprodione, and partially propanil, but not procymidone and phenylureas indicating a structure-dependent specificity related to the substituents of the carboxamide moiety.

AB - Ozone dynamics in two urban background atmospheres over middle Indo-Gangetic Plain (IGP) were studied in two contexts: total columnar and ground-level ozone. In terms of total columnar ozone (TCO), emphases were made to compare satellite based retrieval with ground-based observation and existing trend in decadal and seasonal variation was also identified. Both satellite-retrieved (Aura Ozone Monitoring Instrument-Differential Optical Absorption Spectroscopy (OMI-DOAS)) and ground-based observations (IMD-O3) revealed satisfying agreement with OMI DOAS observation over predicting TCO with a positive bias of 7.24 % under all-sky conditions. Minor variation between daily daytime (r = 0.54; R 2 = 29 %; n = 275) and satellite overpass time-averaged TCO (r = 0.58; R 2 = 34 %; n = 208) was also recognized. A consistent and clear seasonal trend in columnar ozone (2005-2015) was noted with summertime (March-June) maxima (Varanasi, 290.9 +/- 8.8; Lucknow, 295.6 +/- 9.5 DU) and wintertime (December-February) minima (Varanasi, 257.4 +/- 10.1; Lucknow, 258.8 +/- 8.8 DU). Seasonal trend decomposition based on locally weighted regression smoothing technique identified marginally decreasing trend (Varanasi, 0.0084; Lucknow, 0.0096 DU year-1) especially due to reduction in monsoon time minima and summertime maxima. In continuation to TCO, variation in ground-level ozone in terms of seasonality and precursor gases were also analysed from September 2014 to August 2015. Both stations registered similar pattern of variation with Lucknow representing slightly higher annual mean (44.3 +/- 30.6; range, 1.5-309.1 MUg/m3) over Varanasi (38.5 +/- 17.7; range, 4.9-104.2 MUg/m3). Variation in ground-level ozone was further explained in terms water vapour, atmospheric boundary layer height and solar radiation. Ambient water vapour content was found to associate negatively (r = -0.28, n = 284) with ground-level ozone with considerable seasonal variation in Varanasi. Implication of solar radiation on formation of ground-level ozone was overall positive (Varanasi, 0.60; Lucknow, 0.26), while season-specific association was recorded in case of atmospheric boundary layer.

AB - The conventional unhairing process in leather making utilises large amount of lime and sodium sulphide which is hazardous and poses serious waste disposal concerns. Under acidic conditions, sodium sulphide liberates significant quantities of hydrogen sulphide which causes frequent fatal accidents. Further, the conventional unhairing process involves destruction of the hair leading to increased levels of biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS) and total suspended solids (TSS) in the effluent. A safe approach is needed to overcome such environmental and health problems through an eco-benign process. The present study deals with a clean technology in which the keratinous body is detached from the dermis using enzymes produced from Bacillus crolab MTCC 5468 by solid state fermentation (SSF) as an alternative to noxious chemicals. Complete unhairing of skin could be achieved with an enzyme concentration of 1.2 % (w/w). The bio-chemical parameters of the spent liquor of the enzymatic process were environmentally favourable when compared with conventional method. The study indicates that the enzymatic unhairing is a safe process which could be used effectively in leather processing to alleviate pollution and health problems. PMID- 27704383 TI - Dissipation and residue of clothianidin in granules and pesticide fertilizers used in cabbage and soil under field conditions. AB - The single application of 0.5 % clothianidin granules, a novel formulation, was used to control pests in vegetables under a high dose. In this article, residues of clothianidin in cabbage and soil samples under field conditions from Guangzhou, Nanning, and Qianjiang were determined by HPLC. The terminal residues of clothianidin in cabbage were less than the limit of detection (=45 years. Three of four patients with lymph node metastasis also showed soft tissue extension. In conclusion, TGDC carcinomas (TGDCCa) are uncommon, with all classical PTC. For "microcarcinomas" (<=1 cm), conservative management can be used for patients <45 years (i.e., Sistrunk procedure only); for >1 cm tumors, and due to the high incidence of concurrent papillary carcinoma and higher stage at presentation in older patients, completion thyroidectomy is recommended for patients >=45 years. Thus, even though a good prognosis can be expected for PTC developing in TGDCs, staging is advocated to more appropriately match therapeutic interventions. PMID- 27704387 TI - Differences in Patterns of Mortality Between Foreign-Born and Native-Born Workers Due to Fatal Occupational Injury in the USA from 2003 to 2010. AB - This study assesses differences mortality patterns and relative hazard due to fatal occupational injuries between native and immigrant workers in the US. Fatal occupational injury data from 2003 to 2010 were examined using survival analysis based on proportional hazards models controlling for categorical variables of race, gender, occupation, and industry. Workers are stratified based on whether they are native to the US (n = 31952) or born abroad (n = 7096). Foreign-born workers are further stratified into region of birth. Foreign-born workers had an adjusted hazard ratio of 1.148 (95 % CI 1.109:1.189) relative to native workers. Stratifying foreign-born workers into region of origin revealed significantly higher adjusted risk of work fatality relative to native workers for most foreign regions. Of fatally injured workers, foreign-born workers have shorter survival before succumbing to traumatic injury during their time of occupational 'exposure' in the workforce. Native-born workers tend to incur fatal injuries at older ages after longer 'exposure'. PMID- 27704386 TI - Molecular and histologic characteristics of pseudoprogression in diffuse gliomas. AB - During the 6 month period following chemoradiotherapy, gliomas frequently develop new areas of contrast enhancement, which are due to treatment effect rather than tumor progression. We sought to characterize this phenomenon in oligodendrogliomas (OG) and mixed oligoastrocytomas (MOA). We reviewed the imaging findings from 143 patients with a WHO grade II or III OG or MOA for evidence of pseudoprogression (PsP) or early tumor progression. We characterized these cases for 1p/19q codeletions by FISH, IDH1 R132H mutation by immunohistochemistry, and TP53, ATRX, and EGFR mutations by next generation sequencing. We then reviewed the pathologic specimens of the patient cases in which a re-resection was performed. We found that OG and MOA that are 1p/19q intact developed PsP at a higher rate than tumors that are 1p/19q codeleted (27 vs. 8 %). Moreover, IDH1 wild-type (WT) tumors developed PsP at a higher rate than IDH1 R132H cases (27 vs. 11 %). Patients with ATRX or TP53 mutations developed PsP at an intermediate rate of 21 %. Ten patients in our cohort underwent a re-resection for early contrast enhancement; these tumors were predominantly 1p/19q intact (90 %) and had a low rate of IDH1 R132H mutation (50 %). 8 of 10 tumors demonstrated primarily treatment effects, while the remaining 2 of 10 demonstrated recurrent/residual tumor of the same grade. Early contrast enhancement that develops during the first 6 months after chemoradiotherapy is typically due to PsP and occurs primarily in OG and MOA that are 1p/19q intact and IDH WT. PMID- 27704388 TI - Primary Care Screening Methods and Outcomes for Asylum Seekers in New York City. AB - Effective screening in primary care among asylum-seekers in the US is critical as this population grows. This study aimed to evaluate disease prevalence and screening methods in this high-risk group. Two hundred ten new clients from 51 countries, plus Tibet, who were accepted into a program for asylum seekers from 2012 to 2014 were included. Screening rates and outcomes for infectious, non communicable, and mental illnesses were evaluated. Screening rates were highest for PTSD, depression, hepatitis B, and latent tuberculosis. Seventy-one percent of clients screened positive for depression and 55 % for PTSD, followed by latent tuberculosis (41 %), hypertension (10 %), hepatitis B (9.4 %), and HIV (0.8 %). Overall screening rates were high. Point of care testing was more effective than testing that required a repeat visit. A large psychiatric and infectious disease burden was identified. These findings can inform future primary care screening efforts for asylum seekers in the US. PMID- 27704390 TI - Utility Estimates of Disease-Specific Health States in Prostate Cancer from Three Different Perspectives. AB - OBJECTIVE: To develop a statistical model generating utility estimates for prostate cancer specific health states, using preference weights derived from the perspectives of prostate cancer patients, men at risk for prostate cancer, and society. METHODS: Utility estimate values were calculated using standard gamble (SG) methodology. Study participants valued 18 prostate-specific health states with the five attributes: sexual function, urinary function, bowel function, pain, and emotional well-being. Appropriateness of model (linear regression, mixed effects, or generalized estimating equation) to generate prostate cancer utility estimates was determined by paired t-tests to compare observed and predicted values. Mixed-corrected standard SG utility estimates to account for loss aversion were calculated based on prospect theory. RESULTS: 132 study participants assigned values to the health states (n = 40 men at risk for prostate cancer; n = 43 men with prostate cancer; n = 49 general population). In total, 792 valuations were elicited (six health states for each 132 participants). The most appropriate model for the classification system was a mixed effects model; correlations between the mean observed and predicted utility estimates were greater than 0.80 for each perspective. CONCLUSIONS: Developing a health-state classification system with preference weights for three different perspectives demonstrates the relative importance of main effects between populations. The predicted values for men with prostate cancer support the hypothesis that patients experiencing the disease state assign higher utility estimates to health states and there is a difference in valuations made by patients and the general population. PMID- 27704389 TI - The duration of acute kidney injury after cardiac surgery increases the risk of long-term chronic kidney disease. AB - BACKGROUND: Acute kidney injury (Dasta et al., Nephrol Dial Transplant 23(6):1970 1974, 2008) following cardiac surgery is associated with higher perioperative morbidity and mortality, but its impact on long term development of chronic kidney disease (CKD) is uncertain. METHODS: A total of 350 patients submitted to elective cardiac surgery were evaluated for AKI, defined as an increase in serum creatinine (SCr) >= 0.3 mg/dL over baseline value. Univariate and multivariate analysis were used to study pre, intra and postoperative parameters associated with occurrence CKD after 12 months of follow-up. RESULTS: AKI incidence was 41 % (n = 88). The 12-month prevelence of CKD was 9 % (n = 19) in non-AKI patients versus 25 % (n = 54, p < 0.0001) in the AKI group. The factors identified as independent risk factors for long-term CKD development in the multivariate logistic regression model were age >60 years, hospitalization serum creatinine >0.8 mg/dL, peripheral artery disease, hemorrhage and AKI duration > 3 days. CONCLUSION: Patients developing AKI after cardiac surgery presented high prevalence of long-term incident CKD. The duration of AKI was a strong independent risk factor for this late CKD development. Recognition of predictive factors for CKD development following cardiac surgery-associated AKI may help to develop strategies to prevent or halt CKD progression in this population. PMID- 27704391 TI - The Conundrum of Modern Art : Prestige-Driven Coevolutionary Aesthetics Trumps Evolutionary Aesthetics among Art Experts. AB - Two major mechanisms of aesthetic evolution have been suggested. One focuses on naturally selected preferences (Evolutionary Aesthetics), while the other describes a process of evaluative coevolution whereby preferences coevolve with signals. Signaling theory suggests that expertise moderates these mechanisms. In this article we set out to verify this hypothesis in the domain of art and use it to elucidate Western modern art's deviation from naturally selected preferences. We argue that this deviation is consistent with a Coevolutionary Aesthetics mechanism driven by prestige-biased social learning among art experts. In order to test this hypothesis, we conducted two studies in which we assessed the effects on lay and expert appreciation of both the biological relevance of the given artwork's depicted content, viz., facial beauty, and the prestige specific to the artwork's associated context (MoMA). We found that laypeople appreciate artworks based on their depictions of facial beauty, mediated by aesthetic pleasure, which is consistent with previous studies. In contrast, experts appreciate the artworks based on the prestige of the associated context, mediated by admiration for the artist. Moreover, experts appreciate artworks depicting neutral faces to a greater degree than artworks depicting attractive faces. These findings thus corroborate our contention that expertise moderates the Evolutionary and Coevolutionary Aesthetics mechanisms in the art domain. Furthermore, our findings provide initial support for our proposal that prestige driven coevolution with expert evaluations plays a decisive role in modern art's deviation from naturally selected preferences. After discussing the limitations of our research as well as the relation that our results bear on cultural evolution theory, we provide a number of suggestions for further research into the potential functions of expert appreciation that deviates from naturally selected preferences, on the one hand, and expertise as a moderator of these mechanisms in other cultural domains, on the other. PMID- 27704392 TI - Ancestry Testing and the Practice of Genetic Counseling. AB - Ancestry testing is a home DNA test with many dimensions; in some cases, the implications and outcomes of testing cross over into the health sphere. Common reasons for seeking ancestry testing include determining an estimate of customer's ethnic background, identifying genetic relatives, and securing a raw DNA data file that can be used for other purposes. As the ancestry test marketplace continues to grow, and third-party vendors empower the general public to analyze their own genetic material, the role of the genetic counselor is likely to evolve dramatically. Roles of the genetic counselor may include assisting clients with the interpretation of and adaptation to these results, as well as advising the companies involved in this sector on the ethical, legal, and social issues associated with testing. This paper reviews the history, fundamentals, intended uses, and unintended consequences of ancestry genetic testing. It also discusses the types of information in an ancestry testing result, situations that might involve a clinical genetic counselor, and the benefits, limitations, and functions that ancestry genetic testing can play in a clinical genetics setting. PMID- 27704393 TI - Effects of Type 1 Diabetes on Osteoblasts, Osteocytes, and Osteoclasts. AB - PURPOSE OF REVIEW: To describe the effects of type 1 diabetes on bone cells. RECENT FINDINGS: Type 1 diabetes (T1D) is associated with low bone mineral density, increased risk of fractures, and poor fracture healing. Its effects on the skeleton were primarily attributed to impaired bone formation, but recent data suggests that bone remodeling and resorption are also compromised. The hyperglycemic and inflammatory environment associated with T1D impacts osteoblasts, osteocytes, and osteoclasts. The mechanisms involved are complex; insulinopenia, pro-inflammatory cytokine production, and alterations in gene expression are a few of the contributing factors leading to poor osteoblast activity and survival and, therefore, poor bone formation. In addition, the observed sclerostin level increase accompanied by decreased osteocyte number and enhanced osteoclast activity in T1D results in uncoupling of bone remodeling. T1D negatively impacts osteoblasts and osteocytes, whereas its effects on osteoclasts are not well characterized, although the limited studies available indicate increased osteoclast activity, favoring bone resorption. PMID- 27704394 TI - Bone Microarchitecture in Type 1 Diabetes: It Is Complicated. AB - Patients with type 1 diabetes (T1DM) experience a disproportionate number of fractures for their bone mineral density (BMD). Differences in bone microarchitecture from those without the disease are thought to be responsible. However, the literature is inconclusive. New studies of the microarchitecture using three-dimensional imaging have the advantage of providing in vivo estimates of "bone quality," rather than examining areal BMD alone. There are drawbacks in that most studies have been done on those with less than a 30-year duration of T1DM, and the techniques used to measure vary as do the sites assessed. In addition to the rise in these imaging techniques, very recent literature presents evidence of an intimate relationship between skeletal health and vascular complications in T1DM. The following review provides an overview of the available studies of the bone microarchitecture in T1DM with a discussion of the burgeoning field of complications and skeletal health.

AB - Temporomandibular disorders (TMDs) are among the most common maxillofacial complaints and a major cause of orofacial pain. Although current treatments provide short- and long-term relief, alternative tissue engineering solutions are in great demand. Particularly, the development of strategies, providing long-term resolution of TMD to help patients regain normal function, is a high priority. An absolute prerequisite of tissue engineering is to understand normal structure and function. The current knowledge of anatomical, mechanical, and biochemical characteristics of the temporomandibular joint (TMJ) and associated tissues will be discussed, followed by a brief description of current TMD treatments. The main focus is on recent tissue engineering developments for regenerating TMJ tissue components, with or without a scaffold. The expectation for effectively managing TMD is that tissue engineering will produce biomimetic TMJ tissues that recapitulate the normal structure and function of the TMJ. PMID- 27704396 TI - Advanced Glycation End Products, Diabetes, and Bone Strength. AB - Diabetic patients have a higher fracture risk than expected by their bone mineral density (BMD). Poor bone quality is the most suitable and explainable cause for the elevated fracture risk in this population. Advanced glycation end products (AGEs), which are diverse compounds generated via a non-enzymatic reaction between reducing sugars and amine residues, physically affect the properties of the bone material, one of a component of bone quality, through their accumulation in the bone collagen fibers. On the other hand, these compounds biologically act as agonists for these receptors for AGEs (RAGE) and suppress bone metabolism. The concentrations of AGEs and endogenous secretory RAGE, which acts as a "decoy receptor" that inhibits the AGEs-RAGE signaling axis, are associated with fracture risk in a BMD-independent manner. AGEs are closely associated with the pathogenesis of this unique clinical manifestation through physical and biological mechanisms in patients with diabetes mellitus. PMID- 27704398 TI - The RET E616Q Variant is a Gain of Function Mutation Present in a Family with Features of Multiple Endocrine Neoplasia 2A. AB - The REarranged during Transfection (RET) proto-oncogene is a receptor tyrosine kinase involved in growth and differentiation during embryogenesis and maintenance of the urogenital and nervous systems in mammals. Distinct mutations across hotspot RET exons can cause Multiple Endocrine Neoplasia Type 2A (MEN2A) characterised by development of medullary thyroid cancer (MTC), phaeochromocytoma (PCC) and primary hyperparathyroidism (PHPT), with a strong correlation between genotype and phenotype. Here, we report a 42-year-old man presented in the clinic with a unilateral PCC, with subsequent investigations revealing a nodular and cystic thyroid gland. He proceeded to thyroidectomy, which showed bilateral C cell hyperplasia (CCH) without evidence of MTC. His brother had neonatal Hirschsprung disease (HSCR). Genetic testing revealed the presence of a heterozygous variant of unknown significance (VUS) in the cysteine-rich region of exon 10 in the RET gene (c.1846G>C, p.E616Q), in both affected siblings and their unaffected mother. Exon 10 RET mutations are known to be associated with HSCR and MEN2. Variants in the cysteine-rich region of the RET gene, outside of the key cysteine residues, may contribute to the development of MEN2 in a less aggressive manner, with a lower penetrance of MTC. Currently, a VUS in RET cannot be used to inform clinical management and direct future care. Analysis of RETE616Q reveals a gain of function mutant phenotype for this variant, which has not previously been reported, indicating that this VUS should be considered at risk for future clinical management. PMID- 27704400 TI - Certolizumab Pegol: A Review in Inflammatory Autoimmune Diseases. AB - Certolizumab pegol (Cimzia(r)) is a subcutaneously administered polyethylene glycolylated (PEGylated) antigen-binding fragment of a recombinant human monoclonal antibody that selectively neutralizes TNFalpha. The drug is indicated for a variety of inflammatory autoimmune diseases, including Crohn's disease (CD), rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA), based on its benefit in these settings in well designed clinical trials. In these studies, certolizumab pegol (as first- or subsequent-line therapy) reduced the severity of CD when used as an induction or maintenance therapy, and improved the signs/symptoms and slowed the radiographic progression of RA (with or without concomitant methotrexate), PsA and axSpA. Certolizumab pegol is generally well tolerated, with upper respiratory tract infections, rash and urinary tract infections being among the most frequent adverse reactions. Thus, certolizumab pegol is an effective option for the management of these autoimmune diseases. PMID- 27704399 TI - Consensus on the management of advanced radioactive iodine-refractory differentiated thyroid cancer on behalf of the Spanish Society of Endocrinology Thyroid Cancer Working Group (GTSEEN) and Spanish Rare Cancer Working Group (GETHI). AB - Thyroid cancer is the single most prevalent endocrine malignancy; differentiated thyroid cancer (DTC) accounts for more than 90 % of all malignancies and its incidence has been rising steadily. For more patients, surgical treatment, radioactive iodine (RAI) ablation, and thyroid-stimulating hormone (TSH) suppressive therapy achieve an overall survival (OS) rate of 97.7 % at 5 years. Nevertheless, locoregional recurrence occurs in up to 20 % and distant metastases in approximately 10 % at 10 years. Two-thirds of these patients will never be cured with radioactive iodine therapy and will become RAI-refractory, with a 3 year OS rate of less than 50 %. Over the last decade, substantial progress has been made in the management of RAI-refractory DTC. Given the controversy in some areas, the Spanish Task Force for Thyroid Cancer on behalf of Spanish Society of Endocrinology Thyroid Cancer Working Group (GTSEEN) and the Spanish Rare Cancer Working Group (GETHI) have created a national joint task force to reach a consensus addressing the most challenging aspects of management in these patients. In this way, multidisciplinary management should be mandatory and nuclear medicine targeted therapy, novel molecular targeted agents, and combinations are currently changing the natural history of RAI-refractory DTC. PMID- 27704402 TI - The effect of losartan therapy on ventricular function in Marfan patients with haploinsufficient or dominant negative FBN1 mutations. AB - BACKGROUND: Mild biventricular dysfunction is often present in patients with Marfan syndrome. Losartan has been shown to reduce aortic dilatation in patients with Marfan syndrome. This study assesses the effect of losartan on ventricular volume and function in genetically classified subgroups of asymptomatic Marfan patients without significant valvular regurgitation. METHODS: In this predefined substudy of the COMPARE study, Marfan patients were classified based on the effect of their FBN1 mutation on fibrillin-1 protein, categorised as haploinsufficient or dominant negative. Patients were randomised to a daily dose of losartan 100 mg or no additional treatment. Ventricular volumes and function were measured by magnetic resonance imaging at baseline and after 3 years of follow-up. RESULTS: Changes in biventricular dimensions were assessed in 163 Marfan patients (48 % female; mean age 38 +/- 13 years). In patients with a haploinsufficient FBN1 mutation (n = 43), losartan therapy (n = 19) increased both biventricular end diastolic volume (EDV) and stroke volume (SV) when compared with no additional losartan (n = 24): left ventricular EDV: 9 +/- 26 ml vs. -8 +/- 24 ml, p = 0.035 and right ventricular EDV 12 +/- 23 ml vs. -18 +/- 24 ml; p < 0.001 and for left ventricle SV: 6 +/- 16 ml vs. -8 +/- 17 ml; p = 0.009 and right ventricle SV: 8 +/- 16 ml vs. -7 +/- 19 ml; p = 0.009, respectively. No effect was observed in patients with a dominant negative FBN1 mutation (n = 92), or without an FBN1 mutation (n = 28). CONCLUSION: Losartan therapy in haploinsufficient Marfan patients increases biventricular end diastolic volume and stroke volume, furthermore, losartan also appears to ameliorate biventricular filling properties. PMID- 27704403 TI - Grazing and abandonment determine different tree dynamics in wood-pastures. AB - Wood-pastures are threatened biotopes in which trees and livestock grazing maintain high conservation values. However, browsing may threaten tree regeneration, whereas abandonment leads to tree encroachment. We studied the regeneration of trees in a grazed and abandoned boreal wood-pastures. In grazed sites, the density of young spruces (Picea abies) was high, while the density of young birches (Betula spp.) was very low. Sprucification can be prevented only by removing spruces. The number of young birches and pines (Pinus sylvestris) was correlated with the number of junipers (Juniperus communis), probably because thorny junipers protect palatable seedlings from browsing. In abandoned sites, deciduous trees and spruces regenerated abundantly. In the long term, both grazing and abandonment lead to changes in tree species compositions and low diversity wood-pastures. Landscape scale planning and disturbance dynamics are needed for the creation of new wood-pastures and the maintenance of all pasture types within the landscape. PMID- 27704404 TI - Tablet Splitting of Antiepileptic Drugs in Pediatric Epilepsy: Potential Effect on Plasma Drug Concentrations. AB - INTRODUCTION: Tablet splitting is the process of dividing a tablet into portions to obtain a prescribed dose of medication. Very few studies have investigated whether split parts of a tablet deliver the expected amount of drug to patients. OBJECTIVE: Our objectives were to evaluate the split parts of adult-dose tablet formulations for percentage of weight deviation, weight uniformity, weight loss, drug content, and the content uniformity of four antiepileptic drugs (AEDs) prescribed to pediatric patients. We also measured AED plasma concentrations in the children. METHODS: We chose to study first-line AEDs (phenytoin sodium [PHE], sodium valproate [SVA], carbamazepine, and phenobarbitone) as they are routinely prescribed in India. We asked caregivers to perform the same splitting process they follow in their homes on three whole tablets during their routine visit to the outpatient department. After caregivers split the tablets, we studied the weight and content of the split parts. We also used high-performance liquid chromatography to study plasma drug concentrations in children who had received split AEDs for at least 4 months. RESULTS: A total of 168 caregivers participated in the study, and we analyzed 1098 split tablet parts. In total, 539 (49.0 %) split parts were above the specified limit of the 2010 Indian Pharmacopeia (IP) acceptable percentage weight deviation (PHE 169 [48.8 %], SVA 187 [51.9 %], carbamazepine 56 [41.1 %], phenobarbitone 127 [49.6 %]); 456 (41.5 %) split parts were outside the proxy IP specification for drug content (PHE 135 [39.0 %], SVA 140 [38.8 %], carbamazepine 51 [37.5 %], phenobarbitone 130 [50.7 %]), and 253 split parts were outside the acceptable content uniformity range of <85 % and >115 % (PHE 85 [24.5 %], SVA 98 [27.2 %], carbamazepine 14 [10.2 %], phenobarbitone 56 [21.8 %]). In total, 130 (72.2 %) patients had plasma drug concentrations outside the therapeutic range (PHE 36 [72.0 %], SVA 39 [78.0 %], carbamazepine 34 [68.0 %], phenobarbitone 21 [70.0 %]). CONCLUSIONS: Splitting adult-dosage formulations of AEDs results in patients not receiving the optimal dose. Plasma drug concentrations are also not optimal. Pediatric dosage formulations should be preferred to splitting adult-dosage formulations in pediatric epilepsy. PMID- 27704405 TI - The influence of interoceptive awareness on functional connectivity in patients with irritable bowel syndrome. AB - Irritable bowel syndrome (IBS) is characterized by visceral hypersensitivity likely related to altered processing of sensory stimuli along the brain-gut axis. Previous neuroimaging studies demonstrated structural and functional alteration of several brain areas involved in bodily representation, e.g. the insula, in patients with IBS. By means of resting-state functional magnetic resonance imaging (rs-fMRI) we searched for alteration of functional connectivity within the network involved in self-bodily consciousness. We found significant inverse correlation between hypochondriasis assessed through a clinical questionnaire and connectivity between posterior cingulate cortex and left supramarginal gyrus, extending into the adjacent superior temporal gyrus. Moreover, we observed a significant and positive correlation between a clinical questionnaire assessing interoception and connectivity between left anterior ventral insula and two clusters located in supramarginal gyrus bilaterally.Our findings highlight an "abnormal network synchrony" reflecting functional alteration, in the absence of structural and micro-structural changes, which might represent a possible therapeutic target for Irritable Bowel Syndrome. PMID- 27704407 TI - Subthalamic nucleus stimulation effects on single and combined task performance in Parkinson's disease patients: a PET study. AB - Subthalamic nucleus deep brain stimulation (STN-DBS) represents one of the most efficacious treatments for Parkinson's disease, along with L-dopa therapy. The objective of the present work was to identify the cerebral networks associated with hand movement and speech production tasks performed alone and simultaneously, as well as the effects of STN-DBS on these profiles. Clinical, behavioral, and neuroimaging (oxygen 15-labeled water and Positron Emission Tomography) investigations were used to study single and combined performances of unilateral hand movements and speech production in 11 unmedicated individuals with PD, both off and on STN-DBS. Specifically, a flexible factorial design with the tasks (hand movement, speech production, combined task) and the STN-DBS conditions (off, on) as main factors was chosen for brain activation statistical analysis, using a Family-Wise Error corrected p-value at the cluster level of at least 10 contiguous voxels. Increased activation of fronto-parietal and cingulate areas was observed under STN-DBS for hand movement in single and combined tasks, respectively, reflecting a partial restoration of cortico-sub-cortical connections. The lack of results for speech production for both off and on STN DBS could illustrate its relatively poor response to the treatment. STN-DBS tended to restore the additive function capacity that can be achieved when performing the combined task. We confirmed with original neuroimaging data that speech is much less responsive to STN-DBS than any other motor function and we concluded that speech outcomes following STN-DBS can be different from those observed pre-operatively following L-dopa administration. PMID- 27704406 TI - White matter abnormalities are associated with overall cognitive status in blast related mTBI. AB - Blast-related mild traumatic brain injury (mTBI) is a common injury of the Iraq and Afghanistan Wars. Research has suggested that blast-related mTBI is associated with chronic white matter abnormalities, which in turn are associated with impairment in neurocognitive function. However, findings are inconsistent as to which domains of cognition are affected by TBI-related white matter disruption. Recent evidence that white matter abnormalities associated with blast related mTBI are spatially variable raises the possibility that the associated cognitive impairment is also heterogeneous. Thus, the goals of this study were to examine (1) whether mTBI-related white matter abnormalities are associated with overall cognitive status and (2) whether white matter abnormalities provide a mechanism by which mTBI influences cognition. Ninety-six Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OEF) veterans were assigned to one of three groups: no-TBI, mTBI without loss of consciousness (LOC) (mTBI-LOC), and mTBI with LOC (mTBI + LOC). Participants were given a battery of neuropsychological tests that were selected for their sensitivity to mTBI. Results showed that number of white matter abnormalities was associated with the odds of having clinically significant cognitive impairment. A mediation analysis revealed that mTBI + LOC was indirectly associated with cognitive impairment through its effect on white matter integrity. These results suggest that cognitive difficulties in blast-related mTBI can be linked to injury-induced neural changes when taking into account the variability of injury as well as the heterogeneity in cognitive deficits across individuals. PMID- 27704409 TI - Neural mapping of guilt: a quantitative meta-analysis of functional imaging studies. AB - Guilt is a self-conscious emotion associated with the negative appraisal of one's behavior. In recent years, several neuroimaging studies have investigated the neural correlates of guilt, but no meta-analyses have yet identified the most robust activation patterns. A systematic review of literature found 16 functional magnetic resonance imaging studies with whole-brain analyses meeting the inclusion criteria, for a total of 325 participants and 135 foci of activation. A meta-analysis was then conducted using activation likelihood estimation. Additionally, Meta-Analytic Connectivity Modeling (MACM) analysis was conducted to investigate the functional connectivity of significant clusters. The analysis revealed 12 significant clusters of brain activation (voxel-based FDR-corrected p < 0.05) located in the prefrontal, temporal and parietal regions, mainly in the left hemisphere. Only the left dorsal cingulate cluster survived stringent FWE correction (voxel-based p < 0.05). Secondary analyses (voxel-based FDR-corrected p < 0.05) on the 7 studies contrasting guilt with another emotional condition showed an association with clusters in the left precuneus, the anterior cingulate, the left medial frontal gyrus, the right superior frontal gyrus and the left superior temporal gyrus. MACM demonstrated that regions associated with guilt are highly interconnected. Our analysis identified a distributed neural network of left-lateralized regions associated with guilt. While voxel-based FDR corrected results should be considered exploratory, the dorsal cingulate was robustly associated with guilt. We speculate that this network integrates cognitive and emotional processes involved in the experience of guilt, including self-representation, theory of mind, conflict monitoring and moral values. Limitations of our meta-analyses comprise the small sample size and the heterogeneity of included studies, and concerns about naturalistic validity. PMID- 27704408 TI - Altered functional connectivity within and between the default model network and the visual network in primary open-angle glaucoma: a resting-state fMRI study. AB - To explore the alterations of functional connectivity (FC) and connections within and between the subnetworks of the visual network and the default mode network in glaucoma. We applied the independent component analysis to obtain two resting state networks (RSNs), which were the visual network and the default mode network (DMN), from the resting-state fMRI data of 25 primary open-angle glaucoma (POAG) patients and 25 well-matched normal controls. Then FC analysis was performed to obtain the altered FC within the RSNs, whereas the functional network connectivity (FNC) analysis was performed within and between these two RSNs. The abnormalities were correlated with clinical measures in glaucoma to investigate the abnormality-clinical relationship. FC analysis showed that the FC in the occipital pole of the visual network was decreased in POAG patients while no alterations were found in the FC of the DMN in patients. FNC analysis of connections within the RSNs found that two of the three connections within the visual network were decreased while no connection alterations were found within the DMN. FNC analysis of connections between these two RSNs found two increased connections and one decreased connection. The decreased connection between these two RSNs was positively correlated with the visual field mean deviation. These findings shed light on the importance of the reorganization of resting state networks in glaucoma mechanism, which may facilitate the understanding of glaucoma. PMID- 27704411 TI - ?

AB - Assessing functional brain activation patterns in neuropsychiatric disorders such as cocaine dependence (CD) or pathological gambling (PG) under naturalistic stimuli has received rising interest in recent years. In this paper, we propose and apply a novel group-wise sparse representation framework to assess differences in neural responses to naturalistic stimuli across multiple groups of participants (healthy control, cocaine dependence, pathological gambling). Specifically, natural stimulus fMRI (N-fMRI) signals from all three groups of subjects are aggregated into a big data matrix, which is then decomposed into a common signal basis dictionary and associated weight coefficient matrices via an effective online dictionary learning and sparse coding method. The coefficient matrices associated with each common dictionary atom are statistically assessed for each group separately. With the inter-group comparisons based on the group wise correspondence established by the common dictionary, our experimental results demonstrated that the group-wise sparse coding and representation strategy can effectively and specifically detect brain networks/regions affected by different pathological conditions of the brain under naturalistic stimuli.

AB - Wireless body area network (WBANs) is composed of sensors that collect and transmit a person's physiological data to health-care providers in real-time. In order to guarantee security of this data over open networks, a secure data transmission mechanism between WBAN and application provider's servers is of necessity. Modified medical data does not provide a true reflection of an individuals state of health and its subsequent use for diagnosis could lead to an irreversible medical condition. In this paper, we propose a lightweight certificateless signcryption scheme for secure transmission of data between WBAN and servers. Our proposed scheme not only provides confidentiality of data and authentication in a single logical step, it is lightweight and resistant to key escrow attacks. We further provide security proof that our scheme provides indistinguishability against adaptive chosen ciphertext attack and unforgeability against adaptive chosen message attack in random oracle model. Compared with two other Diffie-Hellman based signcryption schemes proposed by Barbosa and Farshim (BF) and another by Yin and Liang (YL), our scheme consumes 46 % and 8 % less energy during signcryption than BF and YL scheme respectively.

AB - In this paper we have proposed an iterative Fuzzy C-Mean (IFCM) method which divides the pixels present in the image into a set of clusters. This set of clusters is then used to segment a focal liver lesion from a liver ultrasound image. Advantage of IFCM methods is that n-clusters FCM method may lead to non uniform distribution of centroids, whereas in IFCM method centroids will always be uniformly distributed. Proposed method is compared with the edge based Active contour Chan-Vese (CV) method, and MAP-MRF method by implementing the methods on MATLAB. Proposed method is also compared with region based active contour region scalable fitting energy (RSFE) method whose MATLAB code is available in author's website. Since no comparison is available on a common database, the performance of three methods and the proposed method have been compared on liver ultrasound (US) images available with us. Proposed method gives the best accuracy of 99.8 % as compared to accuracy of 99.46 %, 95.81 % and 90.08 % given by CV, MAP-MRF and RSFE methods respectively. Computation time taken by the proposed segmentation method for segmentation is 14.25 s as compared to 44.71, 41.27 and 49.02 s taken by CV, MAP-MRF and RSFE methods respectively. PMID- 27704459 TI - Enhancement of Structured Reporting - an Integration Reporting Module with Radiation Dose Collection Supporting. AB - Collection of radiation dose derived from radiological examination is necessary not only for radiation protection, but also for fulfillment of structured reports. However, the material regarding of radiation dose cannot be directly utilized by the Radiological Information System (RIS) since it is generated and only stored in the Picture Archiving and Communication System (PACS). In this paper, an integration reporting module is proposed to facilitate handling of dose information and structured reporting by providing two functionalities. First, a gateway is established to automatically collect the related information from PACS for further analyzing and monitoring the accumulated radiation. Second, the designated structured reporting patterns with corresponding radiation dose measurements can be acquired by radiologists as necessary. In the design, the radiation dose collection gateway and the well-established pattern are collocated to achieve that there is no need to do manual entry for structured reporting, thus increasing productivity and medical quality. PMID- 27704460 TI - Advances in Green Organic Sonochemistry. AB - Over the past 15 years, sustainable chemistry has emerged as a new paradigm in the development of chemistry. In the field of organic synthesis, green chemistry rhymes with relevant choice of starting materials, atom economy, methodologies that minimize the number of chemical steps, appropriate use of benign solvents and reagents, efficient strategies for product isolation and purification and energy minimization. In that context, unconventional methods, and especially ultrasound, can be a fine addition towards achieving these green requirements. Undoubtedly, sonochemistry is considered as being one of the most promising green chemical methods (Cravotto et al. Catal Commun 63: 2-9, 2015). This review is devoted to the most striking results obtained in green organic sonochemistry between 2006 and 2016. Furthermore, among catalytic transformations, oxidation reactions are the most polluting reactions in the chemical industry; thus, we have focused a part of our review on the very promising catalytic activity of ultrasound for oxidative purposes. PMID- 27704462 TI - Genome-wide scan in two groups of HIV-infected patients treated with dendritic cell-based immunotherapy. AB - We performed a retrospective genome-wide association study in HIV-infected individuals who were treated with dendritic cell-based immunotherapy in clinical trials performed by two research groups (Spain and Brazil). We aimed to identify host genetic variants influencing treatment response. The Illumina Human Core Exome 12 v 1.0 Bead Chip with over 250,000 markers was used to analyze genetic factors affecting treatment response. Additionally, we performed a meta-analysis of the results obtained from Spanish and Brazilian patients. We identified a genetic variation (rs7935564 G allele) in TRIM22 gene, which encodes TRIM22 protein acting like a HIV restriction factor, as being associated with good response to dendritic cell-based immunotherapy. We then verified the impact of TRIM22 rs7935564 SNP in susceptibility to HIV infection and disease progression by assessing the influence of biogeographic ancestry in the distribution of allelic and genotype frequencies in three populations from Italy, Brazil and Zambia. TRIM22 rs7935564 genotyping indicated association of G rs7935564 allele with long-term non-progression of HIV disease in Italian patients, thus corroborating our hypothesis that it is involved as a restriction factor in dendritic cell-based immunotherapy response. TRIM22 rs7935564 polymorphism was associated with good response to dendritic cell-based immunotherapy. We hypothesize that in selecting patients for treatment, there is a possible bias related to the natural presence of restriction factors that are genetically determined and could influence final outcome of therapy. PMID- 27704463 TI - 2-Deoxy glucose regulate MMP-9 in a SIRT-1 dependent and NFkB independent mechanism. AB - MMP9 is a member of the family of zinc-containing endopeptidases which degrade various components of the extracellular matrix, thereby regulating matrix remodeling. Since matrix remodeling plays an important role during growth and progression of cancer and considering the fact that, tumor cells switch to aerobic glycolysis as its major energy source, this study was designed to analyze if partial inhibition of glycolysis (the major energy pathway during hypoxia) can be used as a means to control matrix remodeling in terms of MMP9 activity and expression. For this, human epithelial carcinoma cells were treated with glycolytic inhibitor, 2-deoxy glucose (2DG) at sub-lethal concentrations followed by analysis of the expression and activity of MMP2 and MMP9. The experimental findings demonstrate that exposure of cancer cells to glycolytic inhibitor at concentration that does not induce ER stress, downregulates the activity and expression of MMP9 without affecting the expression levels and activity of MMP2. Further mechanistic analysis revealed that the regulation of MMP9 was mediated in a SIRT-1 dependent mechanism and did not alter the NFkB signaling pathway. The overall results presented here, therefore suggest that the use of glycolytic inhibitor, 2DG at concentration that do not affect cell viability or induce ER stress can be an effective strategy to control matrix remodeling. PMID- 27704464 TI - GL-9 peptide regulates gene expression of CD44 cancer marker and pro-inflammatory cytokine TNF-alpha in human lung epithelial adenocarcinoma cell line (A549). AB - In this study, we examined cytotoxic effect of GL-9 peptide on A459 cell line through studying the changes in TNF-alpha and CD44 gene expression and ROS production. Real-time PCR analysis showed that the treated A549 cells highly over expressed TNF-alpha, which was associated with a significant reduction of CD44 gene expression levels (p < 0.05). ROS production rate was measured through the usage of DCFH-DA primer. Results demonstrated that GL-9 peptide could also induce cell death via ROS production. The effect of GL-9 peptide on human erythrocytes and leukocytes was analyzed. GL-9 peptide showed no significant toxic effect on human blood cells. Our results suggested that the GL-9 peptide as a potent natural agent could modulate gene expression of cancer cell markers. PMID- 27704465 TI - Lymphocyte genotoxicity and protective effect of Calyptranthes tricona (Myrtaceae) against H2O2-induced cell death in MCF-7 cells. AB - Calyptranthes tricona is a species (Myrtaceae) native to South Brazil. Plants belonging to this family are folkloric used for analgesia, inflammation, and infectious diseases. However, little is known about the toxic potential of C. tricona. The present study aimed to evaluate the antioxidant activity of C. tricona ethanol and hexane leaf extracts, as well as verify their effect on human lymphocytes and MCF-7 cells. The extracts were subjected to preliminary phytochemical screening, antioxidant activity using DPPH and ORAC methods. Genotoxic and mutagenic effects in cultured human lymphocytes were assessed using the comet assay and the micronucleus assay, respectively. In addition, cell viability by MTT assay and fluorometric analysis of mitochondrial potential and caspases-9 activity were performed in order to verify the possible effects of both extracts on H2O2-induced cell death of MCF-7 cells. Our findings revealed that the phenol content and the antioxidant activity were only present in the ethanol extract. Also, the phytochemical screening presented steroids, triterpenoids, condensed tannins, and flavones as the main compounds. However, both extracts were capable of inducing concentration-dependent DNA damage in human lymphocytes. When treating MCF-7 cells with the extracts, both of them inhibited MCF-7 cell death in response to oxidative stress through a decrease of mitochondrial depolarization and caspases-9 activity. Thus, our results need to be considered in future in vitro and in vivo studies of C. tricona effects. In the meanwhile, we recommend caution in the acute/chronic use of this homemade preparation for medicinal purpose. PMID- 27704466 TI - Anti-arthritogenic and cardioprotective action of hesperidin and daidzein in collagen-induced rheumatoid arthritis. AB - Atherosclerosis has been linked to chronic inflammatory processes. Changes in the levels of lipoproteins, especially low-density lipoprotein or its variants, as well as inflammatory markers are risk factors for the atherosclerosis. In the present study, an experimental model of rheumatoid arthritis was developed by administrating collagen suspension intradermally in the tail region of Wistar albino rats. At the same time, a suspension of hesperidin (50 mg/kg body weight) and daidzein (20 mg/kg body weight) was orally administrated. The compounds were given in the morning and evening for 21 days. Levels of inflammatory markers in the homogenate of knee joints of experimental rats as well as plasma lipoproteins were investigated. The administration of hesperidin and daidzein caused significant (p < 0.001) decrease in articular elastase activity, TNF-alpha, and malondialdehyde levels. Further, arthritis scoring and histological findings supported the anti-inflammatory actions of the test compounds. Interestingly, the test compounds also lowered the plasma low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, and triglyceride but increased the level of high-density lipoprotein cholesterol. The test compounds thus ameliorated the risk factors of atherosclerosis. Furthermore, antioxidant roles of hesperidin as well as daidzein were evident from decrease in free radical load demonstrated as increase in total antioxidant level in plasma of arthritic animals treated with hesperidin and daidzein. In a separate in vitro experiment, enhanced free radical scavenging activity of hesperidin was demonstrated against 2,2-diphenyl-1 picrylhydrazyl and 2,2-azinobis-3-ethylbenzothiazoline-6-sulfonic acid. The anti inflammatory, hypolipidemic, and antioxidant actions of the naturally occurring test compounds, particularly hesperidin, seem to be quite effective against rheumatoid arthritis and atherosclerosis. Thus, their consumption may be helpful in prevention or at least delaying the onset of these diseases in susceptible individuals. PMID- 27704467 TI - Palliative and End-of-Life Care in Myelodysplastic Syndromes. AB - A growing literature demonstrates that MDS is associated with significant impairments in overall quality of life. Given the poor prognosis for many patients with MDS, and the considerable morbidities associated with this disease, there is a critical need to address palliative and end-of-life care needs in this population. However, palliative and end-of-life care issues are under-represented in the MDS literature. In this article, we highlight a growing body of literature that demonstrates unmet palliative and end-of-life care needs in hematologic malignancies, including MDS, and highlight opportunities for further research and quality improvement initiatives to address unmet needs in MDS care. PMID- 27704469 TI - Growth and yield performance of Pleurotus ostreatus (Jacq. Fr.) Kumm (oyster mushroom) on different substrates. AB - Mushroom cultivation is reported as an economically viable bio-technology process for conversion of various lignocellulosic wastes. Given the lack of technology know-how on the cultivation of mushroom, this study was conducted in Wondo Genet College of Forestry and Natural Resource, with the aim to assess the suitability of selected substrates (agricultural and/or forest wastes) for oyster mushroom cultivation. Accordingly, four substrates (cotton seed, paper waste, wheat straw, and sawdust) were tested for their efficacy in oyster mushroom production. Pure culture of oyster mushroom was obtained from Mycology laboratory, Department of Plant Biology and Biodiversity Management, Addis Ababa University. The pure culture was inoculated on potato dextrose agar for spawn preparation. Then, the spawn containing sorghum was inoculated with the fungal culture for the formation of fruiting bodies on the agricultural wastes. The oyster mushroom cultivation was undertaken under aseptic conditions, and the growth and development of mushroom were monitored daily. Results of the study revealed that oyster mushroom can grow on cotton seed, paper waste, sawdust and wheat straw, with varying growth performances. The highest biological and economic yield, as well as the highest percentage of biological efficiency of oyster mushroom was obtained from cotton seed, while the least was from sawdust. The study recommends cotton seed, followed by paper waste as suitable substrates for the cultivation of oyster mushroom. It also suggests that there is a need for further investigation on various aspects of oyster mushroom cultivation in Ethiopia to promote the industry. PMID- 27704470 TI - Recovery of platinum(0) through the reduction of platinum ions by hydrogenase displaying yeast. AB - Biological technologies for recycling rare metals, which are essential for high tech products, have attracted much attention because they could prove to be more environmentally friendly and energy-saving than other methods. We have developed biological recycling technologies by cell surface engineering for the selective recovery of toxic heavy metal ions and rare metal ions from aqueous wastes. In this study, we aimed to construct a unique biological technique to recover rare metals 'in solid' form by reducing rare metal ions, leading to a practical next generation recovery system. Sulfate-reducing bacteria (SRB) can reduce Pt(II) to Pt(0), and hydrogenases of SRB contribute to the reduction. Therefore, we constructed yeasts displaying their hydrogenases on the 'cell membrane', and reduction experiments were performed under anaerobic conditions without any electron donors. As a result, hydrogenase-displaying yeasts produced black precipitates in PtCl42- solution. Based on X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) observations, the constructed yeasts were found to successfully produce the precipitates of Pt(0) through the reduction of Pt(II). Interestingly, the precipitates of Pt(0) were formed as nanoparticles, suitable for industrial usage. PMID- 27704471 TI - Expression, purification and immobilization of tannase from Staphylococcus lugdunensis MTCC 3614. AB - Enzymes find their applications in various industries, due to their error free conversion of substrate into product. Tannase is an enzyme used by various industries for degradation of tannin. Biochemical characterization of a specific enzyme from one organism to other is one of the ways to search for enzymes with better traits for industrial applications. Here, tannase encoding gene from Staphylococcus lugdunensis was cloned and suitability of the enzyme in various conditions was analysed to find its application in various industry. The recombinant protein was expressed with 6* His tag and purified using nickel affinity beads. The enzyme was purified up to homogeneity, with approximate molecular weight of 66 kDa. Purified tannase exhibited specific activity of about 716 U/mg. Optimum enzyme activity was found to be 40 degrees C at pH 7.0. Biochemical characterization revealed; metal ions such as Zn2+, Fe2+, Fe3+ and Mn2+ inhibited tannase activity, and SDS at lower concentration, increased tannase activity. Non polar organic solvents increased the tannase activity and polar solvents inhibited the tannase activity. Tannase immobilization studies show protection of the enzyme under wide range of pH and temperature. Also in this study we report a method for recovery and repeated use of the tannase.

AB - Sezary syndrome (SS) is a rare and aggressive type of cutaneous T cell lymphoma (CTCL) characterized by an intensely pruritic, exfoliative rash, known as erythroderma, with cutaneous and systemic dissemination of clonal CD4+ T cells into the blood and lymph nodes. This review aims to present recent advancements in the biological and clinical aspects of SS. We begin by providing an overview of the diagnostic criteria for SS and reviewing some of its epidemiological and clinical aspects. We then discuss updates in the etiology of this elusive disease and the genetic and molecular landscapes that define it. Finally, we provide a short overview of the current therapeutic strategies for SS as well as recent advances in the prognosis of this disease. A brief set of recommendations is provided regarding future directions in research and therapy. PMID- 27704472 TI - [Revival after Ebola: multidisciplinary assessment at 1 year, prospect and follow up study of surviving patients from Ebola in Guinea (PostEboGui cohort)]. AB - Ebola virus disease (EVD) epidemic that spread in West Africa from the end of 2013 to early 2016 has reached more people than all past epidemics. Beyond care management of acute phase ill patients and measures for the control of the epidemic, the outcome of Ebola survivors became an important question as their number increased and raised new issues. A multidisciplinary prospective cohort of survivors in Guinea has been launched by IRD UMI 233 and Donka National Hospital, Conakry, Guinea, to assess the long-term clinical, psychological, sociological, immunological, and viral outcomes potentially related to EVD. This paper describes PostEboGui Programme, constraints and changes to the initial proposal, participants, first results, and new issues, 1 year after its start, in a descriptive and critical view. We started also to work on ethical aspects in the context of epidemics and of mass interventions with a risk of overinvestigation of patients. PMID- 27704473 TI - Direct Visualization of Neurotransmitters in Rat Brain Slices by Desorption Electrospray Ionization Mass Spectrometry Imaging (DESI - MS). AB - Mass spectrometry imaging (MSI) of neurotransmitters has so far been mainly performed by matrix-assisted laser desorption/ionization (MALDI) where derivatization reagents, deuterated matrix and/or high resolution, or tandem MS have been applied to circumvent problems with interfering ion peaks from matrix and from isobaric species. We herein describe the application of desorption electrospray ionization mass spectrometry imaging (DESI)-MSI in rat brain coronal and sagittal slices for direct spatial monitoring of neurotransmitters and choline with no need of derivatization reagents and/or deuterated materials. The amino acids gamma-aminobutyric (GABA), glutamate, aspartate, serine, as well as acetylcholine, dopamine, and choline were successfully imaged using a commercial DESI source coupled to a hybrid quadrupole-Orbitrap mass spectrometer. The spatial distribution of the analyzed compounds in different brain regions was determined. We conclude that the ambient matrix-free DESI-MSI is suitable for neurotransmitter imaging and could be applied in studies that involve evaluation of imbalances in neurotransmitters levels. Graphical Abstract ?. PMID- 27704474 TI - Separation of cis and trans Isomers of Polyproline by FAIMS Mass Spectrometry. AB - High field asymmetric waveform ion mobility spectrometry (FAIMS) is well established as a tool for separating peptide isomers (sequence inversions and post-translationally modified localization variants). Here, we demonstrate the FAIMS is able to differentiate cis and trans isomers of polyproline. Polyproline assumes an all-cis conformation-the PPI helix-in 1-propanol, and an all-trans conformation-the PPII helix-in aqueous solutions. Differentiation of these conformers may be achieved both through use of a cylindrical FAIMS device and a miniaturized ultrahigh field planar FAIMS device. Graphical Abstract ?. PMID- 27704475 TI - Expression and Enzyme Activity Detection of a Sepiapterin Reductase Gene from Musca domestica Larva. AB - Tetrahydrobiopterin (BH4) is an essential cofactor for aromatic acid hydroxylases and nitric oxide synthase. Sepiapterin reductase (SPR) catalyzes the final steps of BH4 biosynthesis. Studies on SPR from several insects and other organisms have been reported. However, thus far, enzyme activity of SPR in Musca domestica is kept unknown. In this study, 186 differentially expressed genes including SPR gene from Musca domestica (MDSPR) were screened in subtractive cDNA library. The MDSPR gene was cloned, and the recombinant MDSPI16 protein was expressed as a 51 kDa protein in soluble form. The MDSPR exhibited strong activity to the substrate sepiapterin (SP). The values of Vmax and Km of the MDSPR for SP were 6.83 MUM/min and 23.48 MUM, and the optimum temperature and pH of MDSPR were 50 degrees C and 4.0, respectively. This study provides new hypotheses and methods for the production of BH4 using insect-derived SPR. PMID- 27704476 TI - Simultaneous Production of Amyloglucosidase and Exo-Polygalacturonase by Aspergillus niger in a Rotating Drum Reactor. AB - Simultaneous production of amyloglucosidase (AMG) and exo-polygalacturonase (exo PG) was carried out by Aspergillus niger in substrate of defatted rice bran in a rotating drum bioreactor (RDB) and studied by a 31 * 22 factorial experimental design. Variables under study were A. niger strains (A. niger NRRL 3122 and A. niger t0005/007-2), types of inoculum (spore suspension and fermented bran), and types of inducer (starch, pectin, and a mix of both). Solid-state fermentation process (SSF) was conducted at 30 degrees C under 60-vvm aeration for 96 h in a pilot scale. Production of AMG and exo-PG was significantly affected by the fungal strain and the type of inoculum, but inducers did not trigger any significant effect, an evidence of the fact that these enzymes are constitutive. The maximum activity of exo-PG was 84 U gdm-1 whereas the maximum yield of AMG was 886.25 U gdm-1. PMID- 27704477 TI - Physical and Covalent Immobilization of Lipase onto Amine Groups Bearing Thiol Ene Photocured Coatings. AB - In this study, amine groups containing thiol-ene photocurable coating material for lipase immobilization were prepared. Lipase (EC 3.1.1.3) from Candida rugosa was immobilized onto the photocured coatings by physical adsorption and glutaraldehyde-activated covalent bonding methods, respectively. The catalytic efficiency of the immobilized and free enzymes was determined for the hydrolysis of p-nitrophenyl palmitate and also for the synthesis of p-nitrophenyl linoleate. The storage stability and the reusability of the immobilized enzyme and the effect of temperature and pH on the catalytic activities were also investigated. The optimum pH for free lipase and physically immobilized lipase was determined as 7.0, while it was found as 7.5 for the covalent immobilization. After immobilization, the optimum temperature increased from 37 degrees C (free lipase) to 50-55 degrees C. In the end of 15 repeated cycles, covalently bounded enzyme retained 60 and 70 % of its initial activities for hydrolytic and synthetic assays, respectively. While the physically bounded enzyme retained only 56 % of its hydrolytic activity and 67 % of its synthetic activity in the same cycle period. In the case of hydrolysis V max values slightly decreased after immobilization. For synthetic assay, the V max value for the covalently immobilized lipase was found as same as free lipase while it decreased dramatically for the physically immobilized lipase. Physically immobilized enzyme was found to be superior over covalent bonding in terms of enzyme loading capacity and optimum temperature and exhibited comparable re-use values and storage stability. Thus, a fast, easy, and less laborious method for lipase immobilization was developed. PMID- 27704478 TI - Cushing's syndrome and pregnancy outcomes: a systematic review of published cases. AB - Pregnancy in Cushing's syndrome (CS) is extremely rare due to the influence of hypercortisolism on the reproductive axis. Purpose of this study is to investigate whether the etiology of CS in pregnancy determines a different impact on the fetal/newborn and maternal outcomes. We performed a systematic review of cases published in the literature from January 1952 to April 2015 including the words "Cushing AND pregnancy". We included 168 manuscripts containing 220 patients and 263 pregnancies with active CS during pregnancy and with a history of CS but treated and cured hypercortisolism at the time of gestation. Adrenal adenoma was the main cause of active CS during pregnancy (44.1 %). Women with active CS had more gestational diabetes mellitus (36.9 vs. 2.3 %, p = 0.003), gestational hypertension (40.5 vs. 2.3 %, p < 0.001) and preeclampsia (26.3 vs. 2.3 %, p = 0.001) than those with cured disease. The proportion of fetal loss in active CS was higher than in cured CS (23.6 vs. 8.5 %, p = 0.021), as well as global fetal morbidity (33.3 vs. 4.9 %, p < 0.001). The predictors of fetal loss in active CS were etiology of hypercortisolism [Odds Ratio -OR-for pregnancy induced CS 4.7 (95 % Confidence Interval-CI 1.16-18.96), p = 0.03], publication period [OR for "1975-1994" 0.10 (95 % CI 0.03-0.40), p = 0.001] and treatment during gestation (p = 0.037, [OR medical treatment 0.25 (95 % CI 0.06-1.02), p = 0.052], [OR surgical treatment 0.34 (95 % CI 0.11-1.06), p = 0.063]). The period of diagnosis of CS (before, during or after pregnancy) was the only predictor of overall fetal morbimortality [OR for diagnosis during pregnancy 4.66 (95 % CI 1.37-15.83), p = 0.014]. Patients with active CS, especially in pregnancy-induced CS, experienced more problems in pregnancy and had the worst fetal prognosis in comparison to other causes. Diagnosis of CS during pregnancy was also associated with worse overall fetal morbimortality. Both medical treatment and surgery during pregnancy appeared to be protective in avoiding fetal loss.

AB - Despite recent advances in acromegaly treatment by surgery, drugs, and radiotherapy, hormonal control is still not achieved by some patients. The impairment of IGF-1 generation by estrogens in growth hormone deficient patients is well known. Patients on oral estrogens need higher growth hormone doses in order to achieve normal IGF-1 values. In the past, estrogens were one of the first drugs used to treat acromegaly. Nevertheless, due to the high doses used and the obvious side effects in male patients, this strategy was sidelined with the development of more specific drugs, as somatostatin receptor ligands and dopamine agonists. In the last 15 years, the antagonist of growth hormone receptor became available, making possible IGF-1 control of the majority of patients on this particular drug. However, due to its high cost, pegvisomant is still not available in many centers around the world. In this setting, the effect of estrogens and also of selective estrogen receptor modulators on IGF-1 control was reviewed, and proved to be an ancillary tool in the management of acromegaly. This review describes data concerning their efficacy and place in the treatment algorithm of acromegaly. PMID- 27704480 TI - Long-term outcome of multimodal therapy for giant prolactinomas. AB - Giant prolactinomas are rare tumors characterized by their large size, compressive symptoms, and extremely high prolactin secretion. The aim of this study is to describe our experience with a series of 16 giant prolactinomas cases in terms of clinical presentation, therapeutic decisions, and final outcomes. Retrospective analysis of adult patients diagnosed with giant prolactinomas at the endocrine departments of three university tertiary hospitals. We included 16 patients (43.7 % women); mean age at diagnosis: 42.1 +/- 21 years. The most frequent presentation was compressive symptoms. The delay in diagnosis was higher in women (median of 150 months vs. 12 in men; p = 0.09). The mean maximum tumor diameter at diagnosis was 56.9 +/- 15.5 mm, and mean prolactin levels were 10,995.9 +/- 12,157.8 ng/mL. Dopamine agonists were the first-line treatment in 11 patients (mean maximum dose: 3.9 +/- 3.2 mg/week). Surgery was the initial treatment in five patients and the second-line treatment in six. Radiotherapy was used in four cases. All patients but one, are still with dopamine agonists. After a mean follow-up of 9 years, prolactin normalized in 7/16 patients (43.7 %) and 13 patients (81 %) reached prolactin levels lower than twice the upper limit of normal. Mean prolactin level at last visit: 79.5 +/- 143 ng/mL. Tumor volume was decreased by 93.8 +/- 11.3 %, and final maximum tumor diameter was 18.4 +/- 18.8 mm. Three patients are actually tumor free. Giant prolactinomas are characterized by a large tumor volume and extreme prolactin hypersecretion. Multimodal treatment is frequently required to obtain biochemical and tumor control. PMID- 27704481 TI - Heparin-binding protein is important for vascular leak in sepsis. AB - BACKGROUND: Elevated plasma levels of heparin-binding protein (HBP) are associated with risk of organ dysfunction and mortality in sepsis, but little is known about causality and mechanisms of action of HBP. The objective of the present study was to test the hypothesis that HBP is a key mediator of the increased endothelial permeability observed in sepsis and to test potential treatments that inhibit HBP-induced increases in permeability. METHODS: Association between HBP at admission with clinical signs of increased permeability was investigated in 341 patients with septic shock. Mechanisms of action and potential treatment strategies were investigated in cultured human endothelial cells and in mice. RESULTS: Following adjustment for comorbidities and Acute Physiology and Chronic Health Evaluation (APACHE) II, plasma HBP concentrations were weakly associated with fluid overload during the first 4 days of septic shock and the degree of hypoxemia (PaO2/FiO2) as measures of increased systemic and lung permeability, respectively. In mice, intravenous injection of recombinant human HBP induced a lung injury similar to that observed after lipopolysaccharide injection. HBP increased permeability of vascular endothelial cell monolayers in vitro, and enzymatic removal of luminal cell surface glycosaminoglycans (GAGs) using heparinase III and chondroitinase ABC abolished this effect. Similarly, unfractionated heparins and low molecular weight heparins counteracted permeability increased by HBP in vitro. Intracellular, selective inhibition of protein kinase C (PKC) and Rho-kinase pathways reversed HBP mediated permeability effects. CONCLUSIONS: HBP is a potential mediator of sepsis induced acute lung injury through enhanced endothelial permeability. HBP increases permeability through an interaction with luminal GAGs and activation of the PKC and Rho-kinase pathways. Heparins are potential inhibitors of HBP-induced increases in permeability. PMID- 27704482 TI - Molecular Breeding of Rice Restorer Lines and Hybrids for Brown Planthopper (BPH) Resistance Using the Bph14 and Bph15 Genes. AB - BACKGROUND: The development of hybrid rice is a practical approach for increasing rice production. However, the brown planthopper (BPH), Nilaparvata lugens Stal, causes severe yield loss of rice (Oryza sativa L.) and can threaten food security. Therefore, breeding hybrid rice resistant to BPH is the most effective and economical strategy to maintain high and stable production. Fortunately, numerous BPH resistance genes have been identified, and abundant linkage markers are available for molecular marker-assisted selection (MAS) in breeding programs. Hence, we pyramided two BPH resistance genes, Bph14 and Bph15, into a susceptive CMS restorer line Huahui938 and its derived hybrids using MAS to improve the BPH resistance of hybrid rice. RESULTS: Three near-isogenic lines (NILs) with pyramided Bph14 and Bph15 were obtained by molecular marker-assisted backcross (MAB) and phenotypic selection. The genomic components of these NILs were detected using the whole-genome SNP (Single nucleotide polymorphism) array, RICE6K, suggesting that the recurrent parent genome (RPG) recovery of the NILs was 87.88, 87.70 and 86.62 %, respectively. BPH bioassays showed that the improved NILs and their derived hybrids carrying homozygous Bph14 and Bph15 were resistant to BPH. However, the hybrids with heterozygous Bph14 and Bph15 remained susceptible to BPH. The developed NILs showed no significant differences in major agronomic traits and rice qualities compared with the recurrent parent. Moreover, the improved hybrids derived from the NILs exhibited better agronomic performance and rice quality compared with the controls under natural field conditions. CONCLUSIONS: This study demonstrates that it is essential to stack Bph14 and Bph15 into both the maternal and paternal parents for developing BPH-resistant hybrid rice varieties. The SNP array with abundant DNA markers is an efficient tool for analyzing the RPG recovery of progenies and can be used to monitor the donor segments in NILs, thus being extremely important for rice molecular breeding. PMID- 27704483 TI - Slackline Training (Balancing Over Narrow Nylon Ribbons) and Balance Performance: A Meta-Analytical Review. AB - BACKGROUND: Adequate static and dynamic balance performance is an important prerequisite during daily and sporting life. Various traditional and innovative balance training concepts have been suggested to improve postural control or neuromuscular fall risk profiles over recent years. Whether slackline training (balancing over narrow nylon ribbons) serves as an appropriate training strategy to improve static and dynamic balance performance is as yet unclear. OBJECTIVE: The aim was to examine the occurrence and magnitude of effects of slackline training compared with an inactive control condition on static and dynamic balance performance parameters in children, adults and seniors. DATA SOURCES: Five biomedical and psychological databases (CINAHL, EMBASE, ISI Web of Knowledge, PubMed, SPORTDiscus) were screened using the following search terms with Boolean conjunctions: (slacklin* OR slack-lin* OR tight rop* OR tightrop* OR Slackline-based OR line-based OR slackrop* OR slack-rop* OR floppy wir* OR rop* balanc* OR ropedanc* OR rope-danc*) STUDY SELECTION: Randomized and non randomized controlled trials that applied slackline training as an exercise intervention compared with an inactive control condition focusing on static and dynamic balance performance (perturbed and non-perturbed single leg stance) in healthy children, adults and seniors were screened for eligibility. DATA EXTRACTION: Eligibility and study quality [Physiotherapy Evidence Database (PEDro) scale] were independently assessed by two researchers. Standardized mean differences (SMDs) calculated as weighted Hedges' g served as main outcomes in order to compare slackline training versus inactive control on slackline standing as well as dynamic and static balance performance parameters. Statistical analyses were conducted using a random-effects, inverse-variance model. RESULTS: Eight trials (mean PEDro score 6.5 +/- 0.9) with 204 healthy participants were included. Of the included subjects, 35 % were children or adolescents, 39 % were adults and 26 % were seniors. Slackline training varied from 4 to 6 weeks with 16 +/- 7 training sessions on average, ranging from 8 to 28 sessions. Mean overall slackline training covered 380 +/- 128 min. Very large task-specific effects in favor of slackline training compared with the inactive control condition were found for slackline standing time {SMD 4.63 [95 % confidence interval (CI) 3.67 5.59], p < 0.001}. Small and moderate pooled transfer effects were observed for dynamic [SMD 0.52 (95 % CI 0.08-0.96), p = 0.02] and static [SMD 0.30 (95 % CI 0.03 to 0.64), p = 0.07] standing balance performance, respectively. CONCLUSIONS: Slackline training mainly revealed meaningful task-specific training effects in balance performance tasks that are closely related to the training content, such as slackline standing time and dynamic standing balance. Transfer effects to static and dynamic standing balance performance tasks are limited. As a consequence, slackline devices should be embedded into a challenging and multimodal balance training program and not used as the sole form of training. PMID- 27704484 TI - Effect of Plyometric Training on Vertical Jump Performance in Female Athletes: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Plyometric training is an effective method to prevent knee injuries in female athletes; however, the effects of plyometric training on jump performance in female athletes is unclear. OBJECTIVE: The aim of this systematic review and meta-analysis was to determine the effectiveness of plyometric training on vertical jump (VJ) performance of amateur, collegiate and elite female athletes. METHODS: Six electronic databases were searched (PubMed, MEDLINE, ERIC, Google Scholar, SCIndex and ScienceDirect). The included studies were coded for the following criteria: training status, training modality and type of outcome measures. The methodological quality of each study was assessed using the physiotherapy evidence database (PEDro) scale. The effects of plyometric training on VJ performance were based on the following standardised pre-post testing effect size (ES) thresholds: trivial (<0.20), small (0.21-0.60), moderate (0.61-1.20), large (1.21-2.00), very large (2.01-4.00) and extremely large (>4.00). RESULTS: A total of 16 studies met the inclusion criteria. The meta-analysis revealed that plyometric training had a most likely moderate effect on countermovement jump (CMJ) height performance (ES = 1.09; 95 % confidence interval [CI] 0.57-1.61; I 2 = 75.60 %). Plyometric training interventions of less than 10 weeks in duration had a most likely small effect on CMJ height performance (ES = 0.58; 95 % CI 0.25-0.91). In contrast, plyometric training durations greater than 10 weeks had a most likely large effect on CMJ height (ES = 1.87; 95 % CI 0.73-3.01). The effect of plyometric training on concentric-only squat jump (SJ) height was likely small (ES = 0.44; 95 % CI -0.09 to 0.97). Similar effects were observed on SJ height after 6 weeks of plyometric training in amateur (ES = 0.35) and young (ES = 0.49) athletes, respectively. The effect of plyometric training on CMJ height with the arm swing was likely large (ES = 1.31; 95 % CI -0.04 to 2.65). The largest plyometric training effects were observed in drop jump (DJ) height performance (ES = 3.59; 95 % CI -3.04 to 10.23). Most likely extremely large plyometric training effects on DJ height performance (ES = 7.07; 95 % CI 4.71-9.43) were observed following 12 weeks of plyometric training. In contrast, a possibly small positive training effect (ES = 0.30; 95 % CI -0.63 to 1.23) was observed following 6 weeks of plyometric training. CONCLUSION: Plyometric training is an effective form of training to improve VJ performance (e.g. CMJ, SJ and DJ) in female athletes. The benefits of plyometric training on VJ performance are greater for interventions of longer duration (>=10 weeks). PMID- 27704485 TI - Health Care Utilization and Costs Associated with Nausea and Vomiting in Patients Receiving Oral Immediate-Release Opioids for Outpatient Acute Pain Management. AB - INTRODUCTION: Nausea and vomiting (NV) are common side effects of opioid use and limiting factors in pain management. This study sought to quantify the frequency of antiemetic prescribing and the impact of NV on health care resource utilization and costs in outpatients prescribed opioids for acute pain. The perspective was that of a commercial health plan. METHODS: Medical and pharmacy claims from IMS PharMetrics Plus were used to identify patients initiating opioid therapy with a prescription for an oxycodone-, hydrocodone- or codeine-containing immediate-release product for acute use (<=15-day supply) between October 1, 2013 and September 30, 2014. Patients with a medical claim for NV (International Classification of Diseases, Ninth Revision, Clinical Modification codes 787.0x), with or without an antiemetic prescription fill, were compared with patients with no NV claim or antiemetic prescription fill to assess differences in all-cause health care utilization and costs over 1 month. Propensity score matching (PSM) was used to adjust for between-group differences in baseline patient characteristics. RESULTS: The co-prescribing of opioids with antiemetic agents was 10.2%. After PSM (n = 45,790 per group), patients with NV claims had significantly more hospitalizations (11.5% vs 4.2%), emergency department visits (65.0% vs 12.1%), and physician office visits (85.2% vs 64.5%) compared with patients with no NV claims (all P < 0.0001). Mean total health care costs were higher among patients with a NV claim versus those without evidence of the side effect ($6290 vs $2309; P < 0.0001). Among patients with a recent hospitalization, patients with NV claims had higher rates of 30-day rehospitalization than those with no NV claims (24.4% vs 3.0%; P < 0.0001). CONCLUSIONS: Among outpatients prescribed opioids for management of acute pain, co-prescribing with antiemetics was low, and the economic burden associated with NV was high. Efforts to prevent NV in patients receiving opioid therapy may improve patient outcomes and provide cost savings to the health care system. FUNDING: Daiichi Sankyo, Inc. PMID- 27704487 TI - Chemical Composition of Nanoporous Layer Formed by Electrochemical Etching of p Type GaAs. AB - We have performed a detailed characterization study of electrochemically etched p type GaAs in a hydrofluoric acid-based electrolyte. The samples were investigated and characterized through cathodoluminescence (CL), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS). It was found that after electrochemical etching, the porous layer showed a major decrease in the CL intensity and a change in chemical composition and in the crystalline phase. Contrary to previous reports on p-GaAs porosification, which stated that the formed layer is composed of porous GaAs, we report evidence that the porous layer is in fact mainly constituted of porous As2O3. Finally, a qualitative model is proposed to explain the porous As2O3 layer formation on p GaAs substrate. PMID- 27704486 TI - Successful Stepwise Development of Patient Research Partnership: 14 Years' Experience of Actions and Consequences in Outcome Measures in Rheumatology (OMERACT). AB - There is increasing interest in making patient participation an integral component of medical research. However, practical guidance on optimizing this engagement in healthcare is scarce. Since 2002, patient involvement has been one of the key features of the Outcome Measures in Rheumatology (OMERACT) international consensus effort. Based on a review of cumulative data from qualitative studies and internal surveys among OMERACT participants, we explored the potential benefits and challenges of involving patient research partners in conferences and working group activities. We supplemented our review with personal experiences and reflections regarding patient participation in the OMERACT process. We found that between 2002 and 2016, 67 patients have attended OMERACT conferences, of whom 28 had sustained involvement; many other patients contributed to OMERACT working groups. Their participation provided face validity to the OMERACT process and expanded the research agenda. Essential facilitators have been the financial commitment to guarantee sustainable involvement of patients at these conferences, procedures for recruitment, selection and support, and dedicated time allocated in the program for patient issues. Current challenges include the representativeness of the patient panel, risk of pseudo professionalization, and disparity in patients' and researchers' perception of involvement. In conclusion, OMERACT has embedded long-term patient involvement in the consensus-building process on the measurement of core health outcomes. This integrative process continues to evolve iteratively. We believe that the practical points raised here can improve participatory research implementation. PMID- 27704488 TI - Efficiency of an electronic device in controlling tracheal cuff pressure in critically ill patients: a randomized controlled crossover study. AB - BACKGROUND: Despite intermittent control of tracheal cuff pressure (P cuff) using a manual manometer, cuff underinflation (<20 cmH2O) and overinflation (>30 cmH2O) frequently occur in intubated critically ill patients, resulting in increased risk of microaspiration and tracheal ischemic lesions. The primary objective of our study was to determine the efficiency of an electronic device in continuously controlling P cuff. The secondary objective was to determine the impact of this device on the occurrence of microaspiration of gastric or oropharyngeal secretions. METHODS: Eighteen patients requiring mechanical ventilation were included in this prospective randomized controlled crossover study. They randomly received either continuous control of P cuff with Mallinckrodt(r) device for 24 h, followed by discontinuous control with a manual manometer for 24 h, or the reverse sequence. During the 48 h after randomization, P cuff was continuously recorded, and pepsin and alpha amylase were quantitatively measured in tracheal aspirates. P cuff target was 25 cmH2O. RESULTS: Clinical characteristics were similar during the two study periods, as well as mean airway pressure. Percentage of time spent with cuff overinflation or underinflation was significantly lower during continuous control compared with routine care period [median (IQR) 0.8 (0.1, 2) vs 20.9 (3.1, 40.1), p = 0.0009]. No significant difference was found in pepsin [median (IQR) 230 (151, 300) vs 259 (134, 368), p = 0.95] or in alpha amylase level [median (IQR) 1475 (528, 10,333) vs 2400 (1342, 15,391), p = 0.19] between continuous control and routine care periods, respectively. CONCLUSIONS: The electronic device is efficient in controlling P cuff, compared with routine care using a manometer. Further studies are needed to evaluate the impact of this device on intubation-related complications. Trial registration ClinicalTrials.gov Identifier: NCT01965821. PMID- 27704489 TI - Influence of Depression and Hostility on Exercise Tolerance and Improvement in Patients with Coronary Heart Disease. AB - PURPOSE: Although hostility and depression have been linked to higher cardiac risk and poor prognosis of patients with coronary heart disease (CHD), there is a lack of research that studies how they may influence the short-term outcomes among patients participating in cardiac rehabilitation (CR). This study aimed to investigate the influence of hostility and depression on patients' exercise tolerance and improvement trajectory in a CR program over 6 weeks. METHOD: Participants were 142 patients with CHD, with a mean age of 62 years. Latent growth curve modeling was conducted to determine whether hostility and depression predicted patients' baseline exercise tolerance and rates of improvement on treadmill, while controlling for age and severity of illness. In addition, analysis was conducted to examine whether depression mediated the influence of hostility on exercise outcomes. RESULTS: Patients with CHD with higher hostility scores had a lower baseline exercise tolerance and slower rates of improvement over 6 weeks. Depressive symptom severity mediated the influence of hostility on exercise baseline and improvement. Patients with higher hostility were more likely to have more severe depressive symptoms, which in turn were associated with lower baseline exercise tolerance and slower improvement. CONCLUSION: While both hostility and depression predicted the exercise outcomes in CR, depression explained the influence of hostility. The findings underscore the importance of addressing psychosocial issues in treatment of CHD patients and provide support for psychosocial interventions in CR to facilitate patients' recovery.

PMID- 27704490 TI - Enlightening the Cerebellopontine Angle: Intraoperative Indocyanine Green Angiography in Microvascular Decompression for Trigeminal Neuralgia. AB - Background and Study Aims In microvascular decompression of the trigeminal nerve for trigeminal neuralgia (TN), the site of conflict is occasionally difficult to identify. Endoscopy has been described to better evaluate the anatomical conflict in such situations. We hypothesized that indocyanine green (ICG) angiography could allow for better visualization of the compressing artery and its anatomical relation to the nerve. Material and Methods ICG angiography was performed in 17 TN patients undergoing microvascular decompression. We focused on whether ICG angiography is helpful in determining the site of conflict, particularly when not directly visible via the microscope, and whether fluorescence is strong enough to shine through the nerve obliterating the direct view of the compressing vessel. Results In four patients, the site of conflict was immediately apparent after opening the cerebellopontine cistern, and ICG angiography did not provide the neurosurgeon with additional information. In another two patients, imaging quality and fluorescence were too poor. Of the remaining 11 patients with a hidden site of nerve-vessel conflict, ICG angiography was found to be helpful in anticipating the site of compression and the course of the artery in 7 patients, particularly in regard to the so-called shining-through effect through fiber bundles of the thinned nerve. Of all the patients, 88% reported at least improvement or cessation of their symptoms, including all of the patients with a shine-through effect. Conclusion ICG angiography could be a helpful adjunct in decompressing the trigeminal nerve and can guide the surgeon to the nerve-vessel conflict. Intensity of the fluorescence is powerful enough to shine through thinned and splayed trigeminal nerve fiber bundles. PMID- 27704492 TI - Association among Maternal Obesity, Cervical Length, and Preterm Birth. AB - Objective The objective of this study was to determine if mid-trimester cervical length is associated with the inverse relationship between maternal body mass index (BMI) at delivery and spontaneous preterm birth (SPTB). Materials and Methods This was a retrospective cohort of women with a singleton pregnancy without prior SPTB who underwent routine transvaginal cervical length assessment between 18 and 24 weeks. Women were categorized into four BMI groups: (1) 18.5 to 24.9, (2) 25 to 29.9, (3) 30 to 34.9, and (4) >= 35 kg/m2. Univariable and multivariable analyses were conducted to determine whether BMI group was associated with SPTB at < 37, 34, or 32 weeks independent of the cervical length. Results Of the 18,100 women in this analysis, 43.5% had a BMI >= 30. In univariable analysis, increasing BMI group was associated with longer cervical length but not with cervical length < 10th percentile. SPTB at < 37, 35, and 32 weeks was less common among women with higher BMI. In multivariable regression, a higher BMI group was associated with a lower frequency of SPTB at 37 weeks (adjusted odds ratios [aORs] of 0.64, 0.68, and 0.51), at 34 weeks (aORs of 0.53, 0.54, and 0.31) and at 32 weeks (aORs of 0.47, 0.60, and 0.27) for BMI groups 2 to 4, respectively. This association persisted even when cervical length was entered into the model as a covariate. Conclusion Women with a higher BMI group had longer mid-trimester cervical length, and correspondingly reduced SPTB. However, the decreased risk of SPTB was not associated with cervical length. The reason for the potential protective effect from prematurity is unknown and its mechanisms require further investigation. PMID- 27704493 TI - Justin C. McArthur, MBBS, MPH, FAAN, FANA, and Nicoline Schiess, MD, MPH. PMID- 27704494 TI - Pearls and Pitfalls, Part 2. PMID- 27704495 TI - Neuromuscular Diseases. AB - Neuromuscular diseases are a broadly defined group of disorders that all involve injury or dysfunction of peripheral nerves or muscle. The site of injury can be in the cell bodies (i.e., amyotrophic lateral sclerosis [ALS] or sensory ganglionopathies), axons (i.e., axonal peripheral neuropathies or brachial plexopathies), Schwann cells (i.e., chronic inflammatory demyelinating polyradiculoneuropathy), neuromuscular junction (i.e., myasthenia gravis or Lambert-Eaton myasthenic syndrome), muscle (i.e., inflammatory myopathy or muscular dystrophy), or any combination of these sites. Some neuromuscular diseases are also associated with central nervous system disease, such as ALS, but most are restricted to the peripheral nervous system. The multitude of possible sites of injury can make neuromuscular diseases difficult to diagnose. Here the author reviews key features of the clinical presentation that help localize the site of injury and some basic tenets of electromyography. He then shares several pearls in diagnosing and treating patients with specific neuromuscular diseases. PMID- 27704496 TI - Myasthenia Gravis. AB - The basic abnormality in myasthenia gravis (MG) is a reduction in acetylcholine receptors (AChRs) at neuromuscular junctions due to the effects of autoantibodies that are directed against the AChRs in most patients, or against neighboring proteins involved in the clustering of AChRs (MuSK, LRP-4, or agrin). Clinically, MG is characterized by muscle weakness and fatigue, often in typical patterns. The diagnosis may be missed early, and depends on the recognition of clinical manifestations, the measurement of autoantibodies, and/or electrophysiological features. The treatment of MG involves the enhancement of neuromuscular transmission by anticholinesterase drugs (pyridostigmine), and by immunotherapy. Therapy should be designed to improve the clinical features quickly, and keep the symptoms in abeyance over the long term. Rapid improvement can be achieved when necessary by the administration of intravenous immunoglobulin or plasma exchange. Intermediate rates of improvement over months involve the use of adrenal corticosteroids, the calcineurin inhibitors cyclosporine or tacrolimus, and in some patients, the B-cell inhibitor rituximab. For long-term treatment, mycophenolate and azathioprine are the most effective agents. A thymectomy may also have long-term beneficial effects. The majority of MG patients can live normal lives, but most patients require lifelong treatment. The physician's skill in managing the immunotherapeutic agents and avoiding adverse side effects is of paramount importance in the treatment of MG. PMID- 27704497 TI - Acute Visual Loss. AB - Acute visual loss is a frightening experience, a common ophthalmic emergency, and a diagnostic challenge. In this review, the author focusses on the diagnosis of transient monocular blindness and visual loss due to infarction of the retina and/or the optic nerve-the ocular parallel of cerebral stroke. PMID- 27704498 TI - Dizziness. AB - Dizziness and vertigo are among the most common symptoms to bring a patient to a neurologist. Because symptoms are often vague and imprecise, a systematic approach is essential. By categorizing vestibular disorders based on timing, triggers, and duration, as well as through focused oculomotor and vestibular examinations, the vast majority of neuro-otologic diagnoses can be made at the bedside. Here the authors discuss historical and examination pearls for the most common neuro-otologic disorders. PMID- 27704499 TI - Headache. AB - Headache disorders are primarily managed in an outpatient setting; therefore, the authors focus on the primary headache disorders that comprise the bulk of clinical practice. Red flags for secondary headaches that may be more commonly encountered in clinic are briefly discussed. PMID- 27704500 TI - Sleepiness. AB - Sleep medicine can be a particularly rewarding clinical area for neurologists. After all, the driving organ of sleep is the brain. Many of the sleep disorders are primary brain disorders, whereas other sleep disorders (and their medications) influence brain function. But without an organized approach, even the engaged and motivated neurologist can easily become frustrated when dealing with patients whose concerns center on an undesirable degree of sleepiness. Lost in the thicket of information provided during the patient-doctor encounter, many physicians are unable to direct the history toward particular diagnostic hypotheses. So, rather than provide an exhaustive and disorganized set of details about sleep medicine, the author instead shares pearls of sleep medicine in the context of an overall framework, with the goal to foster targeted history-taking for the successful diagnosis of a patient struggling with maintaining wakefulness. The topic of excessive sleepiness will be covered because it is so common and because its mastery is fundamental to approaching most patients with sleep disorders. Common and important pitfalls regarding the topic of sleepiness and how to avoid them-will be discussed. Misdiagnoses and mismanagement are easy to avoid if this entire framework is kept in mind. PMID- 27704501 TI - Low Back Pain and Spondylosis. AB - Low back pain is highly prevalent, affecting a vast majority of the adult population at some point in their lifetime. Thorough history and physical examination is critically important in evaluating these patients and screening for potentially serious conditions. Imaging should be guided by the history and physical examination, particularly when there is concern for serious conditions and/or a focal neurological deficit present. Adequate treatment of patients with low back pain often requires a multidisciplinary approach, involving several medical specialties. Patients with acute axial low back pain typically have a favorable prognosis with resolution over 4 weeks, regardless of treatment. However, patients with chronic low back pain should be transitioned to pain management strategies with multidisciplinary care, in order to maximize function and limit disability. Referral to a spine surgeon is indicated urgently for a severe, progressive neurological deficit, particularly new motor weakness or cauda equina syndrome, and can be done electively for patients with degenerative disorders without a focal deficit. PMID- 27704502 TI - Neuropathic Pain. AB - Diagnosing neuropathic pain and distinguishing it from nociceptive pain can be challenging, but is essential because both forms of pain require different treatment strategies. The diagnosis of neuropathic pain is primarily based on clinical findings. Therefore, a careful, focused history and an examination of the signs characteristic of neuropathic pain are crucial. Imaging techniques and electrophysiological examinations, as well as punch skin biopsy can support the clinical diagnosis. Ideally, treatment should be individualized using a mechanism based approach. However, current treatments are usually dispensed without precision, and calcium-channel-acting modulators (pregabalin, gabapentin), tricyclic antidepressants, and serotonin-noradrenalin reuptake inhibitors (duloxetine, venlafaxine) represent first-line treatment options for neuropathic pain. Although neurostimulation techniques for the treatment of refractory chronic pain have become more important, most evidence of long-term effectiveness and safety is still limited, which strengthens the need for larger randomized controlled trials before final recommendations can be made. PMID- 27704503 TI - Myofascial Trigger Point Pain Syndromes. AB - Myofascial pain syndromes caused by trigger points (TrPs) in muscle are a common cause of local and generalized pain. Trigger points are hyperirritable zones in contracted bands of muscle, thought to be caused by muscle overload or stress. Stress TrPs have characteristic electromyographic features, and can be visualized with ultrasound and magnetic resonance elastography. Trigger point needling or injection can be effective in inactivating TrP, but correcting triggers is also critical. PMID- 27704504 TI - Gait and Balance Assessment. AB - Gait and balance deficits are commonly experienced by individuals with a variety of neurologic disorders. These deficits can be particularly frustrating because they often profoundly impact a person's quality of life. The author applies information about gait and balance based on the neurologic examination and summarizes important relationships among common impairment measures of gait and balance deficits. She also provides an interpretation of these relationships to assist the clinician in how to identify and manage gait and balance deficits. PMID- 27704505 TI - Prof. Daniel H.

AB - Introduction Item analysis is the process of collecting, summarizing and using information from students' responses to assess test items' quality. This study used this approach to evaluate the quality of items and examinations given in the Faculty of Medicine of Tunis (FMT). Methods This study concerned the examinations of 2012-2013 (principal session). It analyzed 3138 items from 66 examinations, of which, 46 were multidisciplinary (187 disciplines). A total of 2515 students took the examinations. "AnItem.xls" file was used for the analysis that focused on difficulty, discrimination and internal consistency. Results Mean difficulty for all examinations was optimum (mean difficulty index: 0.59). Majority of items (89.17%) were either easy or of acceptable difficulty. Mean discrimination for all examinations was moderate (mean item discrimination coefficient: 0.28) with poor discrimination in 23.62% of items. Maximal discrimination occurred with disciplines of difficulty index between 0.4-0.6. " Ideal " items represented 27.02%. Mean internal consistency for all examinations was acceptable (Cronbach's alpha: 0.79). Disciplines with nonacceptable internal consistency (68.45%) contained a maximum of 33 items (each one) and a positive correlation between their alpha and the number of their questions. Distributions were mostly (72.73%) platykurtic and negatively asymmetric (89.39%). First year of studies had the best parameters. Conclusion Our examinations had an acceptable internal consistency, and a good level of difficulty and discrimination. They tended to facility and discriminated basically students of medium level. Item analysis is useful as a guide to item writers to improve the overall quality of questions in the future. PMID- 27704507 TI - Comparison of two oxytocin administration protocols in elective cesarean section: 5 iu versus 10 iu. AB - Background Although Oxytocin is used systematically during caesarean section, no recommendation precise optimal dose for this indication. The bolus administration of 10 IU intravenously after extraction of the newborn, is accompanied by side effects mainly hemodynamic. Objectives To compare two Oxytocin protocols: 05 IU bolus Vs. 10 IU bolus during Cesarean section by studying their respective effectiveness (effects on uterine tone) and adverse effects. Methods A prospective randomized double-blind study including 87 term parturients for undergoing a C-section under loco regional anesthesia. Parturients were randomized into two groups depending on the injected Oxytocine dose : - Group 1 (n = 43): 10 IU + 25 IU IVD in 500 ml of serum / 3h - Group 2 (n = 44): 5 IU IVD + 25 IU in 500 ml serum / 3h. Results The variation of the heart rate and the incidence of low blood pressure were significantly greater for Group 1. No significant differences between the two groups regarding blood loss was noticed per or postoperatively. The type of digestive side effects were more common in the first group. Conclusion Administration of 5 units of Oxytocin during the scheduled C-sections is effective for uterine tone without superimposed bleeding risk, guarantees better hemodynamic stability and less side effects than the 10 units dose. PMID- 27704508 TI - Childhood tuberculosis: A descriptive study in a pneumo-pediatrics department in Tunisia. AB - Objective to assess the different localizations of tuberculosis (TB) in children in a pneumopediatric department in Tunisia and to describe its diagnosis tools since clinical investigations of childhood TB are challenged by the paucibacillary nature of the disease and the difficulties in obtaining specimens. Methods Forty-six cases of TB in children were studied between 2008 and 2013. Clinical history, examination and chest radiography were reported. Several investigations have been conducted to confirm the diagnosis of TB such as: tuberculin skin test (TST), bacteriological and histological investigations. Anti tuberculosis treatment was prescribed according to the national guidelines. Results Cough and deterioration in general condition were the most frequent symptoms (47.8% and 43.7%). The other children presented cervical swelling (19.5%), chest pain (17.4%) and hemoptysis (4.3%). Abnormalities have been found in chest radiography in 35 cases (76%). TST was positive in 73% of cases. Diagnosis of TB was confirmed in 56.6% of cases by Mycobacterium tuberculosis (MT) isolation and/or biopsy. The diagnosis was made on presumptive arguments in 20 cases (43.4%) based on a history of TB contact, suggestive symptoms and a positive TST. A surgical biopsy was necessary for diagnosis in 17 cases (nasopharynx, bone, cervical, mediastinal and mesenteric lymph nodes). Pulmonary TB was diagnosed in 52% of cases. Two children were diagnosed with disseminated TB. A diagnosis delay was noted with an average of 20 days and a contact history was found in 52% of the children. All children were treated according to the national guidelines without major side effects. Healing without sequelae was achieved in 91% of cases. Conclusion Children represent a population at high risk for TB especially after a household contact with a higher frequency of multifocal forms compared to adults. The difficulty of the diagnosis in children may explain partially the diagnosis delay, but efforts must be done to improve prevention and diagnosis in our country. PMID- 27704509 TI - Spectral Domain optical coherence tomography findings in patients with retinitis pigmentosa. AB - Background Maculopathy is a common complication of retinitis pigmentosa (RP), and compromise the visual acuity of RP patients even in the less advanced stages. Aim To report the morphological macular findings detected by spectral domain optical coherence tomography (SD-OCT) and to determine their prevalence in patients with retinitis pigmentosa (RP). Methods SD-OCT scans from 100 patients (196 eyes) affected by RP were reviewed. Results We noted a normal macula appearance in 48.5%, macular edema in 14.5% and macular atrophy in 37%. Mean central macular thickness was 167.79 microns and we did not note any statistically significant correlation between visual acuity and foveal thickness. Visual acuity was statistically better in eyes with a larger number of hyper-reflective layers (p<0.001) and in eyes with photoreceptor inner/outer (IS/OS) segment junction distinct (p<0.001). We have identified three types of tomographic macular edema: a cystoids macular edema in 6.8%, a tractional edema in 8.2% and mixed edema in 1%. We identified two tomographic types of macular atrophy: a central- foveal atrophy in 34 eyes (11.6%) and diffuse atrophy in 38 eyes (12.9%). Epiretinal membrane was present in 24 eyes (8.2%). Conclusions The OCT contributes to the analysis of epidemiological and morphological of different macular involvement in RP. OCT has a prognostic value, which essentially depends on the morphology of the IS/OS line and number of hyper-reflective layers. PMID- 27704510 TI - Nephrocalcinosis in Tunisian children. AB - Background Nephrocalcinosis is rare in children. Its etiologies are multiple. The aim of this study was to analyze the etiology of nephrocalcinosis in Tunisian children. Methods This retrospective study was conducted in the department of pediatrics in Charles Nicolle Hospital during a period of 10 years (2001-2010). Results There were 40 children. The mean age was 3.5 years. The most common signs and symptoms at presentation were growth retardation (42.5%) and hematuria (53.8%). At presentation, renal failure was detected in 70% of patients. The diagnosis of nephrocalcinosis was performed by ultrasonography. The etiology of nephrocalcinosis included primary hyperoxaluria type 1 (65%) and distal renal tubular acidosis (20%). A progression to renal insufficiency was observed in 18 cases. Conclusion Primary oxaluria is the principal cause of nephrocalcinosis; early diagnosis and treatment are mandatory as they help limiting renal function deterioration. PMID- 27704512 TI - What prognosis for Ebstein's anomaly without surgery? Hassan II teaching hospital experience. AB - Background From the first description in 1886, significant progress was made on the treatment of Ebstein disease by mono and bi-ventricular surgery. Aim To highlight the prognosis of Ebstein's anomaly in the pediatric department of Hassan II hospital in Fez. Methods This is a descriptive and retrospective study of 4 years. Results We collected nine patients (seven boys and two girls) with a mean age of 5.3 years. Cyanosis was the main mode of revelation of the disease. In three patients Ebstein's anomaly was part of a malformative syndrome. All patients had only symptomatic medical treatment. Five patients are still alive at a follow up of one to six years. Conclusion Symptomatic medical treatment of Ebstein malformation may improve the prognosis of the disease. PMID- 27704511 TI - Protective effect of Ulva lactuca extract during hepatic cold preservation in rats. AB - Introduction In recent years, many marine resources have drew attention in the research for bio-active compounds to develop new drugs and health foods. (1) Marine algae are now considered as a rich source of antioxidants (2). It is known that seaweeds contain numerous bioactive substances that have the ability to lower cholesterol, reduce blood pressure, promote healthy digestion; and antioxidant activity (3). Natural antioxidants are interesting compounds due to their properties which help prevent oxidative stress (4), among other potentially beneficial actions. For instance, several biological effects have been attributed to flavonoids, such as anti-tumoral, anti-inflammatory, anti-ischemic and anti aggregate plaquetary activities. These activities are believed to be in part related to the antioxidant properties of the compounds, namely in scavenging radical oxygen species (ROS). (5, 6) The cold ischemia constitute a situation of oxidative stress in touch with liberation of oxygenated radicals, these situations incited the researchers to find means for the improvement of the conservation of organs allowing to prolong the durations of the cold ischemia of certain organs (in particular the liver) with conservation of the maximum functional value. However, the constant efforts led by the teams of transplantation to develop transplants, the conservation of organs remains a problem to be resolved. (7) Conservation solution of organ appears as being a stemming to remedy the fatal effects of the ischemia-reperfusion. For our part, we think that seaweeds have not delivered their secrets and yet especially that the marine environment of the Tunisian coast still remains little exploited in spite of the big variety of the fauna and the flora of the coast. We envisage in this work, to study a sort of seaweed collected on the Tunisian quotation in the region of "Chott Meriem" (North West of Tunisia). The purpose of our work is to estimate the capacity of extracts stemming from the green seaweed Ulva lactuca to improve the conservation solution of organs against the hepatic effects of ischemia. PMID- 27704513 TI - Community-acquired pleuropneumonia in children: Bacteriological and therapeutic challenges. AB - Background Community-acquired pleuropneumonia (CPP) is a common complication of pneumonia in children. It is serious given its high morbidity and significant mortality. Aim To study clinical and paraclinical features of CPP in children and to establish a common therapeutic strategy. Methods Our retrospective study included patients who were hospitalized for CPP between 2004 and 2012. All data were collected from patients' medical files. Statistical analysis was made by Epi Info 6. Results One hundred and sixty four patients were registered. The mean age was 32 months (15 days - 14.5 years). The hospital incidence of CPP doubled between 2004 and 2012. The symptomatology was dominated by fever (93.9%), cough (56.7%) and dyspnea (48.1%). The pleural effusion was frequently moderately abundant and loculated. Pleural sample, performed in 53.6% of cases, was the most beneficial bacteriological examination (p=10-6 ). The bacteriological confirmation was attained in 44.5% of cases with the predominance of Staphylococcus aureus (59%) followed by Streptococcus pneumoniae (26%). The S. aureus occurred basically in most young infants (p=0.04) and was responsible for the most severe cases (p=0.01). The CPP management included heterogeneous intravenous antibiotics associated with a pleural drainage in 40% of cases. The quarter of our patients were transferred to an intensive care unit. Six patients died. Conclusion The bacteriological confirmation is difficult. Pleural aspiration is the key tool. S. aureus is the first microorganism followed by S. pneumoniae. A therapeutic strategy is proposed based on large spectrum intravenous antibiotics. The pleural drainage indication is limited. PMID- 27704514 TI - Prevalence of overweight in schools in the rural region of Hazoua (Tozeur). AB - Background Overweight in schools is a worrisome public health problem because they increase medium and long term risks of morbidity and mortality especially with an increased risk of persistence of obesity in adulthood. Aim To estimate the prevalence of overweight among school children and to identify its associated risk factors. Methods this is a descriptive cross-sectional study conducted among school students aged less than 18 years in the area of "Hazoua" (Tozeur). The references of BMI used for overweight and obesity are those of IOTF. The French BMI references are used to establish the prevalence of underweight. Data entry and analysis was performed using SPSS 20. Results Our sample included 445 students. The average BMI was 18.73+/-3.4 kg/m2. The prevalence of Underweight was 9.7%, while overweight and obesity have been reported among 6.7% of students. Overweight was significantly associated to gender and the practice of sport outside school. Conclusion Obesity in schools in the community of Hazoua is now lower than that reported in other studies. In contrast, we detected a problem of underweight, which deserves as much attention. Intervention programs should be established and whose objectives are to improve students' skills in terms of eating behavior and physical activity, these actions require collaboration at all levels. PMID- 27704515 TI - Prevalence and outcomes of thrombocytopenia in a neonatal intensive care unit. AB - Background Thrombocytopenia is a common clinical problem in neonatal intensive care units, affecting about 20 to 35% of all admitted neonates. Even most episodes are mild or moderate, severe episodes could be life-threatening or responsible for sequelae. Objectives The aims of this study were to describe the prevalence, clinical diagnoses, and to determine risk factors for poor prognosis of thrombocytopenia in a neonatal intensive care unit. Methods We carried out a retrospective study in the neonatal intensive care unit of Charles Nicolle Hospital of Tunis, a tertiary neonatal care center, over a four years period (January 2010 to December 2013). All Neonates with at least one episode of confirmed thrombocytopenia were included. Poor prognosis was defined as death or intraventricular hemorrhage >= grade 2 in survivors. Results Of 808 admitted neonates, one hundred (12.4%) had presented at least one episode of confirmed thrombocytopenia, and 12 had presented two episodes of thrombocytopenia. A total of 112 episodes of thrombocytopenia were collected. Thrombocytopenia occurred in the first 3 days of life in 74.1% of cases. Thrombocytopenia was mild in 22.3%, moderate in 36.7% and severe in 41%. Intrauterine growth restriction was the most common cause of early thrombocytopenia. Nosocomial sepsis was the most common cause of late thrombocytopenia. We found that the outcomes of thrombocytopenic neonates depend on, birth weight, gestational age, platelet count, and the underlying cause. Conclusions Thrombocytopenia in neonates can be life threatening, appropriate diagnosis, preventive and therapeutic approach is necessary to prevent death or neurological impairment. PMID- 27704516 TI - Prognostic factors in children with extracranial malignant germ cell tumors: a monocentric pediatric Tunisian study. AB - Background Extracranial Germ cell tumors (GCT) are a rare and a heterogeneous group of pediatric cancers but highly curable. Aim We aimed to review management, outcome and prognostic factors that influence overall survival (OS) in a pediatric Tunisian oncologic unit. Methods We retrospectively evaluated between January 1998 and December 2012, 33 patients affected by extracranial germ cell tumors and treated according to TGM95 protocol established by the SFOPin a pediatric Tunisian oncologic unit. Results Patients had a mean age of 57 months (ranges: 1 day-13 years). There were 19 girls and 14 boys. Primary sites included 12 sacrococcygeal, 11 ovarian, 6 testicular, 3retro peritoneal and 1 mediastinal site. After a mean follow up of 26.1 months (ranges: 0-96 months), OSat 2 years and 5 years were respectively 82% and 75%. Event-free survival were respectively 79% at 2 years and 74% at 5 years. Various prognostic factors have been studied according to Kaplan-Meier. Univariate analyses identified significant factors which influence strongly OS: the stage (p=0.04), the completeness of surgery (p<0.001) and the relapse (p = 0, 0001). A multivariate study showed that only the quality of resection and the clinical stage remained strong significant prognostic factors (p=0,021) for 5-year OS. Conclusion Disease stage, completeness of surgery and relapse have been established as the most powerful prognostic parameter in our analysis. The improvement of survival of patients affected by extracranial germ cell tumors in Tunisia is a real achievement mainly due to the success of salvage treatments. PMID- 27704517 TI - Contribution of verbal autopsy in the study of cancer mortality among reproductive-age women in Tunisia. AB - Background In Tunisia, the information system on medical causes of death is based on the use of standard death certificate model based on international model recommended by the World Organization started in January 2001. However, this system is still burdened with a major death causes of under-registration. Only specific surveys on mortality have FAR generate reliable mortality indicators. Objectives to study the use of verbal autopsy in order to assess cancer mortality among Tunisian women in reproductive age (WRA) . Methods A retrospective national RAMOS survey (Reproductive Age Mortality Study). This survey was conducted in 2010 and included all deaths of women aged 15-49 years which occurred in 2008 and were due to cancer. Data were collected from civil status records and information gathered from families and from health institution's registers. For all deaths of women aged 15-49 years, the detailed circumstances and the sequence of events leading to death were grouped on a folder called "clinical record of verbal autopsy" .Then; all folders were submitted to the independent expert. Results During the study period, 1729 deaths among women of reproductive age (WRA) were the subject of a verbal autopsy against only 708 recorded by the National death information system (NDIS). Cancer is the leading cause of death among WRA .The specific rate of cancer mortality is 17.83 per 100 000 WRA against only 7.91 per 100 000 WRA estimated by the NDIS. Breast cancer is the leading cause with 35% of all cancers and specific death rate of 6.3 per 100,000 WRA against 2.48 per 100,000 WRA recorded by the NDIS. Conclusion Verbal autopsies Verbal autopsy remains an interesting method for measuring cancer mortality in women of a reproductive age especially in countries with a defective national death information system. PMID- 27704518 TI - Primary immunodeficiencies : Report of 33 Pediatric Tunisian cases. AB - Background Primary immunodeficiencies (PID) are a group of heterogeneous and relatively rare diseases. Aim to determine the clinical characteristics, outcome and genetic data of primary immunodeficiencies in pediatrics patients. Methods A retrospective, descriptive and multicentered study, enrolling 33 children presenting a PID in Tunis, during a period of 22 years (1991-2012). Resultats a masculine predominance has been noticed with a sex ratio at 2,3. Consanguinity was found in 71% of family cases. History of early infant deaths was found in 42% of cases. The media age of diagnosis was of 1 year 2 months. The median diagnosis delay was of 11 months and 1/2. Most frenquently observed PID were combined immunodeficiency (36%), mostly severe combined immunodeficiency (SCID) (21%), followed by congenial defects of phagocyte function (33%), mostly chronic granulomatosis disease (21%). Antibody defects were found in 21% of cases. Most frequently observed out comes were lung infections (66%) recurrent oral thrush (57%) and diarrhea (42%). Most important complications were severe infections and bronchiectasis. 30% of patients were dead by the end of the study. A molecular characterization was performed in 33% of patients, and an antenatal diagnosis was performed in 10% of cases. Conclusion The PID are a group of disease with variable expressions and etiologies. Their frequency remains understimated in Tunisia, and their management, difficult and insufficient. We suggest the establishment of systematic genetic consulting visit, the creation of a national registry and developing bone marrow transplantation in children in Tunisia. PMID- 27704519 TI - Exertional heat stroke: about 4 cases. AB - Exertional heat stroke is defined as hyperthermia associated with neurological signs related to intense physical activity performed in a hot environment. This is a medical emergency and life-threatening. In this study, we investigated four cases of exertional heat stroke hospitalized at the military hospital in Tunis (Tunisia) to describe the clinical, therapeutic and preventive characteristics and factors favoring this disease. Four young soldiers, 23 to 44 years older, have developed Exertional heat stroke after Intense and prolonged exercise. Exercises were performed in May and June, in high ambient temperature, high humidity and lack of wind. Three soldiers were in battle dress, a backpack and their weapon. Our four subjects had overweight, were not sufficiently trained and were highly motivated. Insufficient hydration and a diet rich in carbohydrates were noted. Upon hospitalization, patients were febrile and had neurological disorders, neuromuscular disorders, rhabdomyolysis and hemoconcentration. The medical care consisted of a rehydration and oxygen.

PMID- 27704520 TI - The emergent use of Cardiopulmonary bypass and extracorporeal membrane oxygenator in a child with sickle cell disease. AB - The use of Cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenator (ECMO) in patients suffering from Sickle cell disease (SCD) needs specific precautions. Whereas, no consensual protocols have been established to clarify therapeutic management. CASE REPORT A 7-year-old boy was admitted to the hospital for surgery of advanced endocarditis. Major dyspnea, hemodynamic distress and fever were noted on physical examination. Biological tests exploring anaemia revealed Haemoglobin (Hb) S levels of 39.1%. Echocardiography showed important right heart cavities dilation with multiple aortic vegetations. The child was accepted for emergent surgery. Ten minutes after anesthetic induction, serious hemodynamic distress was established. The patient was put on normothermic CPB when he received four packed red-blood-cell. After surgery, he was placed on ECMO support for 2 days than he succumbed. CONCLUSION Urgent cardiac surgery in patients suffering from SCD poses a major therapeutic dilemma. Multiplying case reports and encouraging prospective studies are necessary to define the right place of cardio-pulmonary assistance in treatment protocols for better management.

PMID- 27704523 TI - The effect of bilberries on diabetes-related alterations of interstitial cells of Cajal in the lower oesophageal sphincter in rats. AB - Diabetic gastroenteropathy involves not only the parasympathetic and sympathetic autonomic nerves, but also enteric neurons, smooth muscle cells and interstitial cells of Cajal (ICC). ICC are the cells of mesenchymal origin that occur within and around the muscle layers in the gastrointestinal tract. The objective of the present study was to investigate the alterations of ICC in the lower oesophageal sphincter (LOS) of streptozotocin-nicotinamide non-insulin-dependent diabetes rats. Moreover, we investigated possible ICC in rats with the same type of diabetes, treated with bilberry fruit extract, bearing in mind that its hypoglycemic effect had been already proven. Male Wistar rats (10 weeks old) were used, and diabetes was induced by an intraperitoneal injection of streptozotocin, immediately after intraperitoneal application of nicotinamide. The specimens were exposed to anti-c-kit antibodies to investigate the distribution of ICC, and the smooth muscle cells were immunohistochemically labelled using anti-desmin antibodies. Intramuscular ICC were very abundant in the LOS of rats. They were spindle-shaped, with two long processes connecting them into long linear sequences. In the LOS of diabetic rats, intramuscular ICC were rarely present and linear cell-cell connections between these cells were completely missing. In groups treated with bilberry, the number and distribution of ICC were exactly the same as in the above described rats with induced diabetes. In summary, a decrease of intramuscular ICC, discontinuities and breakdown of contacts between ICC were observed in streptozotocin-nicotinamide induced diabetes rats and in groups treated with bilberry. Bilberry fruit extract was shown to have hypoglycemic activity, but without any protective effects on ICC in the LOS of diabetic rats. PMID- 27704524 TI - Do leprosy and tuberculosis generate a systemic inflammatory shift? Setting the ground for a new dialogue between experimental immunology and bioarchaeology. AB - : It is possible that during long lasting chronic infections such as tuberculosis (TB) and leprosy individuals who generate a stronger immune response will produce a chronic shift in the systemic levels of inflammatory proteins. Consequently, the systemic immunological shift could affect inflammatory responses against other persistent pathogens such as Porphyromonas gingivalis associated with periodontal disease (PD). OBJECTIVE: To determine if in vitro exposure to Mycobacterium tuberculosis or M. leprae lysates impacts subsequent immune responses to P. gingivalis; and to propose a new dialogue between experimental immunology and paleopathology. MATERIAL AND METHODS: We sequentially (2 days protocol) exposed peripheral blood mononuclear cells (PBMCs) from healthy donors to bacterial lysates either from M. tuberculosis, or M. leprae, or P. gingivalis. After collecting all supernatants, we measured the expression of immune proteins TNFalpha and IFNgamma using an enzyme-linked immunosorbent assay. RESULTS: Early exposure (day 1) of PBMCs to M. leprae or M. tuberculosis lysates induces an inflammatory shift detected by the increase of TNFalpha and IFNgamma when the same cells are subsequently (day 2) exposed to oral pathogen P. gingivalis. DISCUSSION: By extrapolating these results, we suggest that chronic infections, such as TB and leprosy, could generate a systemic immunological shift that can affect other inflammatory processes such the one present in PD. We propose that the presence and severity of PD should be explored as a proxy for inflammatory status or competence when reconstructing the health profile in past populations. PMID- 27704525 TI - Declining Amenable Mortality: Time Trend (2000-2013) and Geographic Area Analysis. AB - OBJECTIVE: To update amenable mortality in 32 OECD countries at 2013 (or last available year), to describe the time trends during 2000-2013, and to evaluate the association of these trends with various geographic areas. DATA SOURCES: Secondary data from 32 countries during 2000-2013, gathered from the World Health Organization Mortality Database. STUDY DESIGN: Time trend analysis. DATA COLLECTION: Using Nolte and McKee's list, age-standardized amenable mortality rates (SDRs) were calculated as the annual number of deaths over the population aged 0-74 years per 100,000 inhabitants. We performed a mixed-effects polynomial regression analysis on the annual SDRs to determine whether specific geographic areas were associated with different SDR trajectories over time. PRINCIPAL FINDINGS: The OECD average annual decrease was 3.6/100,000 (p < .001), but slowed over time (coefficient for the quadratic term = 0.11, p < .001). Eastern and Atlantic European countries had the steepest decline (-6.1 and -4.7, respectively), while Latin American countries had the lowest slope (-1.7). The OECD average annual decline during the 14-year period was -0.5 (p < .001) for cancers and -2.5 (p < .001) for cardiovascular diseases, with significant differences among countries. CONCLUSION: Declining trend of amenable SDRs was continuing to 2013 but with steepness change compared with previous periods and with a slowdown. PMID- 27704526 TI - Integrating feeding behavior, ecological data, and DNA barcoding to identify developmental differences in invertebrate foraging strategies in wild white-faced capuchins (Cebus capucinus). AB - OBJECTIVES: Invertebrate foraging strategies in nonhuman primates often require complex extractive foraging or prey detection techniques. As these skills take time to master, juveniles may have reduced foraging efficiency or concentrate their foraging efforts on easier to acquire prey than adults. MATERIALS AND METHODS: We use DNA barcoding, behavioral observations, and ecological data to assess age-based differences in invertebrate prey foraging strategies in a group of white-faced capuchins (Cebus capucinus) in northeastern Costa Rica. Invertebrate availability was monitored using canopy traps and sweep netting. Fecal samples were collected from adult female, adult male, and juvenile white faced capuchins (n = 225). COI mtDNA sequences were compared with known sequences in GenBank and the Barcode of Life Database. RESULTS: Frequencies of Lepidoptera and Hymenoptera consumption were higher in juveniles than in adults. A significantly smaller proportion of juvenile fecal samples contained Gryllidae and Cercopidae sequences, compared with adults (0% and 4.2% vs. 4.6% and 12.5%), and a significantly larger proportion contained Tenthredinidae, Culicidae, and Crambidae (5.6%, 9.7%, and 5.6% vs. 1.3%, 0.7%, and 1.3%). Juveniles spent significantly more time feeding and foraging than adults, and focused their foraging efforts on prey that require different skills to capture or extract. Arthropod availability was not correlated with foraging efficiency, and the rate of consumption of specific orders of invertebrates was not correlated with the availability of those same taxa. DISCUSSION: Our data support the hypothesis that juveniles are concentrating their foraging efforts on different prey than adults, potentially focusing their foraging efforts on more easily acquired types of prey. PMID- 27704527 TI - Cardiovascular risk prevention and all-cause mortality in primary care patients with an abdominal aortic aneurysm. AB - BACKGROUND: Perioperative mortality is low for patients undergoing abdominal aortic aneurysm (AAA) repair, but long-term survival remains poor. Although patients diagnosed with AAA have a significant burden of cardiovascular disease and associated risk factors, there is limited understanding of the contribution of cardiovascular risk management to long-term survival. METHODS: General practice records within The Health Improvement Network (THIN) were examined. Patients with a diagnosis of AAA and at least 1 year of registered medical history were identified from 2000 to 2012. Medical therapies for cardiovascular risk were classified as antiplatelet, statin or antihypertensive agents. Progression to death was investigated using the G-computation formula with time dependent co-variables to account for differences in exposure to cardiovascular risk-modifying treatments and the confounding between exposure, co-morbidities and death. RESULTS: Some 12 485 patients had a recorded diagnosis of AAA. From 2000 to 2012, prescription of medications that modify cardiovascular risk increased: from 26.6 to 76.7 per cent for statins, from 56.5 to 73.9 per cent for antiplatelet agents and from 75.3 to 84.0 per cent for antihypertensive drugs. Adjusted Kaplan-Meier curves demonstrated a better 5-year survival rate in patients receiving statins (68.4 versus 42.2 per cent), antiplatelet agents (63.6 versus 39.7 per cent) or antihypertensive agents (61.5 versus 39.1 per cent), compared with rates in patients not receiving each therapy. CONCLUSION: Appropriate risk factor modification could significantly reduce long-term mortality in patients with AAA. In the UK, up to 30 per cent of patients are not currently receiving these medications. PMID- 27704529 TI - An adaptive Mantel-Haenszel test for sensitivity analysis in observational studies. AB - In a sensitivity analysis in an observational study with a binary outcome, is it better to use all of the data or to focus on subgroups that are expected to experience the largest treatment effects? The answer depends on features of the data that may be difficult to anticipate, a trade-off between unknown effect sizes and known sample sizes. We propose a sensitivity analysis for an adaptive test similar to the Mantel-Haenszel test. The adaptive test performs two highly correlated analyses, one focused analysis using a subgroup, one combined analysis using all of the data, correcting for multiple testing using the joint distribution of the two test statistics. Because the two component tests are highly correlated, this correction for multiple testing is small compared with, for instance, the Bonferroni inequality. The test has the maximum design sensitivity of two component tests. A simulation evaluates the power of a sensitivity analysis using the adaptive test. Two examples are presented. An R package, sensitivity2x2xk, implements the procedure. PMID- 27704528 TI - A joint modeling approach for multivariate survival data with random length. AB - In many biomedical studies that involve correlated data, an outcome is often repeatedly measured for each individual subject along with the number of these measurements, which is also treated as an observed outcome. This type of data has been referred as multivariate random length data by Barnhart and Sampson (1995). A common approach to handling such type of data is to jointly model the multiple measurements and the random length. In previous literature, a key assumption is the multivariate normality for the multiple measurements. Motivated by a reproductive study, we propose a new copula-based joint model which relaxes the normality assumption. Specifically, we adopt the Clayton-Oakes model for multiple measurements with flexible marginal distributions specified as semi-parametric transformation models. The random length is modeled via a generalized linear model. We develop an approximate EM algorithm to derive parameter estimators and standard errors of the estimators are obtained through bootstrapping procedures and the finite-sample performance of the proposed method is investigated using simulation studies. We apply our method to the Mount Sinai Study of Women Office Workers (MSSWOW), where women were prospectively followed for 1 year for studying fertility.

AB - BACKGROUND: In 2011, the Dutch Upper Gastrointestinal Cancer Audit (DUCA) group began nationwide registration of all patients undergoing surgery with the intention of resection for oesophageal or gastric cancer. The aim of this study was to describe the initiation and implementation of this process along with an overview of the results. METHODS: The DUCA is part of the Dutch Institute for Clinical Auditing. The audit provides (surgical) teams with reliable, weekly updated, benchmarked information on process and (case mix-adjusted) outcome measures. To accomplish this, a web-based registration was designed, based on a set of predefined quality measures. RESULTS: Between 2011 and 2014, a total of 2786 patients with oesophageal cancer and 1887 with gastric cancer were registered. Case ascertainment approached 100 per cent for patients registered in 2013. The percentage of patients with oesophageal cancer starting treatment within 5 weeks of diagnosis increased significantly over time from 32.5 per cent in 2011 to 41.0 per cent in 2014 (P < 0.001). The percentage of patients with a minimum of 15 examined lymph nodes in the resected specimen also increased significantly for both oesophageal cancer (from 50.3 per cent in 2011 to 73.0 per cent in 2014; P < 0.001) and gastric cancer (from 47.5 per cent in 2011 to 73.6 per cent in 2014; P < 0.001). Postoperative mortality remained stable (around 4.0 per cent) for patients with oesophageal cancer, and decreased for patients with gastric cancer (from 8.0 per cent in 2011 to 4.0 per cent in 2014; P = 0.031). CONCLUSION: Nationwide implementation of the DUCA has been successful. The results indicate a positive trend for various process and outcome measures. PMID- 27704532 TI - Physical activity and depression: a large cross-sectional, population-based study across 36 low- and middle-income countries. AB - OBJECTIVE: Physical activity (PA) is good for health, yet several small-scale studies have suggested that depression is associated with low PA. A paucity of nationally representative studies investigating this relationship exists, particularly in low- and middle-income countries (LMICs). This study explored the global association of PA with depression and its mediating factors. METHOD: Participants from 36 LMICs from the World Health Survey were included. Multivariable logistic regression analyses were undertaken exploring the relationship between PA and depression. RESULTS: Across 178 867 people (mean +/- SD age = 36.2 +/- 13.5 years; 49.9% male), the prevalence of depression and the prevalence of low PA were 6.6% and 16.8% respectively. The prevalence of low PA was significantly higher among those with depression vs. no depression (26.0% vs. 15.8%, P < 0.0001). In the adjusted model, depression was associated with higher odds for low PA (OR = 1.42; 95% CI = 1.24-1.63). Mediation analyses demonstrated that low PA among people with depression was explained by mobility limitations (40.3%), pain and discomfort (35.8%), disruptions in sleep and energy (25.2%), cognition (19.4%) and vision (10.9%). CONCLUSION: Individuals with depression engage in lower levels of PA in LMICs. Future longitudinal research is warranted to better understand the relationships observed. PMID- 27704531 TI - Greedy outcome weighted tree learning of optimal personalized treatment rules. AB - We propose a subgroup identification approach for inferring optimal and interpretable personalized treatment rules with high-dimensional covariates. Our approach is based on a two-step greedy tree algorithm to pursue signals in a high dimensional space. In the first step, we transform the treatment selection problem into a weighted classification problem that can utilize tree-based methods. In the second step, we adopt a newly proposed tree-based method, known as reinforcement learning trees, to detect features involved in the optimal treatment rules and to construct binary splitting rules. The method is further extended to right censored survival data by using the accelerated failure time model and introducing double weighting to the classification trees. The performance of the proposed method is demonstrated via simulation studies, as well as analyses of the Cancer Cell Line Encyclopedia (CCLE) data and the Tamoxifen breast cancer data. PMID- 27704533 TI - Perimortem caesarean section: Two cases performed in New Zealand hospitals. AB - Perimortem caesarean section is a term many obstetricians are familiar with despite few encountering it first-hand. It is estimated the intervention will be needed every 53 000 maternities. Despite this rarity it is vital clinicians are trained in detecting and intervening where perimortem caesarean is required. In New Zealand eight perimortem caesareans were performed from 2006 to 2013. Here we discuss two perimortem caesarean sections performed in two New Zealand hospitals alongside current guidance and recommendations. PMID- 27704534 TI - The Longitudinal Course of Pain and Analgesic Therapy Following Aneurysmal Subarachnoid Hemorrhage: A Cohort Study. AB - OBJECTIVE: The purpose of this study was to determine the duration, intensity, location, and usual treatment of pain throughout hospitalization following subarachnoid hemorrhage. BACKGROUND: Headache following subarachnoid hemorrhage can be sudden and severe. Little is known about the longitudinal course of headache or its analgesic therapy following the initial diagnosis of subarachnoid hemorrhage. METHODS: A prospectively maintained database of 564 patients diagnosed with cerebral aneurysms collected from 10/2009 to 2/2013 was searched for conscious patients with subarachnoid hemorrhage. Available electronic records were queried for pain scores (0-10/10), location, and analgesic consumption. RESULTS: Forty-six adults with subarachnoid hemorrhage met eligibility criteria for inclusion. Mean [CI 95] daily pain was 3.8 [3.2, 4.4] and maximal daily pain was 5.8 [5.1, 6.6]. Eighty-nine percent of patients reported severe pain of 7 10/10, and 63% of patients reported 10/10 pain at some point during hospitalization. While mean [CI 95] pain declined over the course of hospital stay at a rate of 0.06 [0.04, 0.07] units/day (P < .001), mean [CI 95] maximal daily pain changed at a rate of -0.03 [-0.06, 0.01] units/day, which is not significantly different than zero (P = .15). Pain was located primarily in the head in 76% of subjects but pain in the back, neck, limbs, and eyes was also reported. All patients received oral acetaminophen with increasing daily doses. All but three patients, received opioids, most commonly intravenous fentanyl and oral oxycodone. The mean [95 CI] intravenous morphine equivalent dose of opioids consumed was 15.7 [10.3, 21.1] mg/day and changed at a rate of -0.11 [-0.37, 0.15] mg/day which is not significantly different than zero (P = .40). CONCLUSION: Despite steady consumption of analgesics, the pain reported by conscious patients while recovering from subarachnoid hemorrhage in the hospital is often severe and persists throughout hospitalization. PMID- 27704535 TI - The association between pre-operative variables, including blood pressure, and postoperative kidney function. AB - We used multivariate analyses to assess the association of pre-operative variables with kidney function in 41,523 adults after scheduled surgery in a single large academic hospital. Eight variables were independently associated with a reduction in postoperative estimated glomerular filtration rate: pre operative renal function; age; ASA physical status; cardiac failure; anaemia; cancer; type of surgery; and the lowest quartile of pre-operative mean arterial blood pressure (< 71 mmHg). The estimated glomerular filtration rate fell by a mean (95% CI) of 2.7 (0.04-5.40) ml.min-1 .1.73 m-2 for patients with a pre operative mean arterial pressure < 71 mmHg, p = 0.047. The same variables and male sex were associated with postoperative acute kidney injury. The odds ratio (95% CI) for acute postoperative kidney injury was 1.9 (1.2-2.9) for patients with a pre-operative mean arterial blood pressure < 71 mmHg, p = 0.005. PMID- 27704536 TI - A Neanderthal deciduous human molar with incipient carious infection from the Middle Palaeolithic De Nadale cave, Italy. AB - OBJECTIVES: The aim of the study is the assessment of Nadale 1, a Neanderthal deciduous tooth recently discovered in Northeastern Italy in the De Nadale cave (Middle Palaeolithic). Together with the clear archaeological context of the site, this study brings new insight on Neanderthal behavior and dental morphological variability. MATERIALS AND METHODS: We used microCT data to provide a morphological description and morphometric analysis (diameter measurements and dental tissue volumes) of the Nadale 1 human tooth. Microwear analysis, taphonomical investigation and caries identification were performed using a stereomicroscope and Scanning Electron Microscope. RESULTS: In terms of morphology (i.e., incipient tuberculum molare, marked mesial marginal ridge and well-developed mid-trigonid crest connecting the protoconid and the metaconid, deep anterior fovea) and size, Nadale 1 presents features frequently observed in Neanderthal lower first deciduous molars. Microscope investigations reveal the presence of a small pit which could be correlated to an incipient caries. CONCLUSION: Nadale 1 expands the Italian Middle Palaeolithic fossil record and provides further information on Neanderthal dm1s in terms of dimensional and morphological variability. Furthermore, the presence of an incipient caries brings further data on Neanderthal diet. PMID- 27704537 TI - Systematic review of the prevalence of faecal incontinence. AB - BACKGROUND: Faecal incontinence (FI) is widely recognized as a significant problem in the community. Conjecture exists around the proportion of the population affected. This systematic review evaluated studies reporting the community prevalence of FI in terms of methodology, design and definitions. METHODS: MEDLINE, Embase, CINAHL, the Cochrane Collaboration and National Guideline databases were searched for studies investigating the prevalence of FI in community-based adults published from January 1966 to February 2015. Study data, including methodology, sample size, response rate, definition of FI and prevalence rates, were extracted on to a pro forma and appraised critically. Where possible, FI prevalence estimates were pooled. RESULTS: Thirty studies were analysed from 4840 screened articles. FI prevalence estimates varied from 1.4 to 19.5 per cent. This variation was explained by differences in data collection method and two factors within definitions of FI: type of stool and frequency of FI episodes. When these factors were accounted for, the FI prevalence at a threshold of at least once per month for liquid or solid stool was 8.3-8.4 per cent for face-to-face or telephone interviews, and 11.2-12.4 per cent for postal surveys. The pooled prevalence rate from studies for functional FI (defined by ROME II criteria) was 5.9 (95 per cent c.i. 5.6 to 6.3) per cent. CONCLUSION: When comparable methodologies and definitions are used, studies produce remarkably similar prevalence rates in different community populations. FI remains an unspoken symptom, with lower rates reported in personal interviews compared with anonymous postal questionnaires. PMID- 27704538 TI - Presenting a New, Non-Hormonally Mediated Cyclic Headache in Women: End-Menstrual Migraine. AB - BACKGROUND: This retrospective observational study describes what appears to be a not-uncommon yet not previously typified headache disorder, "end-menstrual migraine" (EMM) named for its proximate occurrence with the terminal days of menstrual bleeding each month. METHODS: Our menstrual migraine (MM) clinic's database was queried for patients with migraine, regular menses, and the locally used diagnostic code of EMM, signifying the patient's assertion that she had migraine at the end of menses as well as calendar data confirming that association. Serum ferritin levels were available for all subjects with EMM. RESULTS: Among the most recently seen 119 women in the clinic, 85 had both regular menses and a diagnosis of migraine, and were thus appropriate for evaluation. In this selected population, 30 women (35.3%) were confirmed to have EMM. Twenty-eight of those 30 patients (93.3%) had ferritin levels that fell below the generally accepted lower desirable limit of 50 ng/mL (mean = 21.9 ng/mL) - half of whom fell below 18 ng/mL, the established minimum levels for women. CONCLUSIONS: EMM is a common complaint in women evaluated for menstrual related migraine (MRM), yet these migraines occur many days after the estrogen withdrawal that precipitates MRM. The authors do not believe that EMM is hormonally mediated, but rather that it is causally related to menstrual blood loss, resulting in a brief relative anemia with consequent migraine. Further study is needed to substantiate this association, search for confounders, and evaluate response to iron therapy. PMID- 27704540 TI - Antenatal pertussis vaccination: Are we implementing best evidence into practice? AB - Maternal immunisation is the most effective strategy to reduce infant morbidity and mortality from pertussis infection, and is now standard of care in many countries, including Australia. However, uptake cannot be guaranteed unless the barriers to implementing programs locally are understood. Education and resources for antenatal care providers, embedding vaccination within antenatal care, and provision of culturally appropriate information for pregnant women are integral to a successful antenatal vaccination program. PMID- 27704539 TI - Poison frog color morphs express assortative mate preferences in allopatry but not sympatry. AB - The concurrent divergence of mating traits and preferences is necessary for the evolution of reproductive isolation via sexual selection, and such coevolution has been demonstrated in diverse lineages. However, the extent to which assortative mate preferences are sufficient to drive reproductive isolation in nature is less clear. Natural contact zones between lineages divergent in traits and preferences provide exceptional opportunities for testing the predicted evolutionary consequences of such divergence. The strawberry poison frog (Oophaga pumilio) displays extreme color polymorphism in and around the young Bocas del Toro archipelago. In a transition zone between red and blue allopatric lineages, we asked whether female preferences diverged along with coloration, and whether any divergent preferences persist in a zone of sympatry. When choosing among red, blue and phenotypically intermediate males, females from monomorphic red and monomorphic blue populations both expressed assortative preferences. However, red, blue, and intermediate females from the contact zone all preferred red males, suggesting that divergent preferences may be insufficient to effect behavioral isolation. Our results highlight the complexity of behavioral isolation, and the need for studies that can reveal the circumstances under which divergent preferences do and do not contribute to speciation. PMID- 27704541 TI - User characteristics, experiences and continuation rates of copper intrauterine device use in a cohort of Australian women. AB - BACKGROUND: Copper intrauterine device (Cu-IUD) use in Australia is low despite being a highly effective, cost effective non-hormonal contraceptive with reported 12-month continuation rates of 85% compared to 59% for oral contraception. AIMS: To describe the characteristics of Cu-IUD users in the Australian context, their experiences of side effects, continuation rates and reasons for discontinuation. METHODS: Between August 2009 and January 2012 we undertook a prospective cohort study of consecutive women presenting for Cu-IUD insertion to three family planning clinics in Queensland and New South Wales. We used survival analysis for continuation rates and univariate and multivariable analyses to characterise users, their experiences up to three years and reasons for discontinuation. RESULTS: Of the 211 enrolled women, a third (36.0%) were aged under 30 and a third were nulliparous (36.5%). Efficacy and lack of hormones were the most frequently cited reasons to choose the method. Four women were lost to follow-up. Overall continuation rates were 79.1% at one year and 61.3% at three years. Early discontinuation was reduced in those with two or more children (adjusted hazards ratio 0.22, 95% CI 0.09-0.50). Heavy menstrual bleeding was the commonest reason for removal in 28 of 59 (47.5%) discontinuations due to complications or side effects. One uterine perforation and one method failure resulting in an ectopic pregnancy occurred. CONCLUSIONS: Cu-IUDs were chosen for their efficacy and lack of hormones by a range of Australian women, including young and nulliparous women. While bleeding-related side effects were relatively common, overall continuation rates were high. Serious complications and failures were rare.

AB - Biologists have taken the concept of organism largely for granted. However, advances in the study of chimerism, symbiosis, bacterial-eukaryote associations, and microbial behavior have prompted a redefinition of organisms as biological entities exhibiting low conflict and high cooperation among their parts. This expanded view identifies organisms in evolutionary time. However, the ecological processes, mechanisms, and traits that drive the formation of organisms remain poorly understood. Recognizing that organismality can be context dependent, we advocate elucidating the ecological contexts under which entities do or do not act as organisms. Here we develop a "contextual organismality" framework and provide examples of entities, such as honey bee colonies, tumors, and bacterial swarms, that can act as organisms under specific life history, resource, or other ecological circumstances. We suggest that context dependence may be a stepping stone to the development of increased organismal unification, as the most integrated biological entities generally show little context dependence. Recognizing that organismality is contextual can identify common patterns and testable hypotheses across different entities. The contextual organismality framework can illuminate timeless as well as pressing issues in biology, including topics as disparate as cancer emergence, genomic conflict, evolution of symbiosis, and the role of the microbiota in impacting host phenotype. PMID- 27704544 TI - Mindfulness training for loneliness among Chinese college students: A pilot randomized controlled trial. AB - Loneliness has been found to predict a wide range of physical and mental health problems. It is suggested that China's One-Child Policy places young Chinese people at a particularly high risk for loneliness. Although loneliness is most prevalent in late adolescence and early adulthood, interventions have primarily targeted children or older adults with limited success. The current study examines a pilot randomized controlled trial of a mindfulness training program among Chinese college students. Participants with elevated loneliness (N = 50, ages 17-25) were randomized into either an 8-week mindfulness training or a control group. Self-reported measures of loneliness and mindfulness were administered at baseline and posttest. The training group also completed a program evaluation form and a 3-month follow-up assessment. Results provided preliminary evidence indicating that the intervention was feasible and effective at reducing loneliness among Chinese college students. Limitations and future directions were discussed. PMID- 27704545 TI - Effect of two doses of urea foliar application on leaves and grape nitrogen composition during two vintages. AB - BACKGROUND: Nitrogen affects grapevine growth and also yeast metabolism, which have a direct influence on fermentation kinetics and the formation of different volatile compounds. Throughout the grapevine cycle, soil nitrogen availability and grape nitrogen composition can vary because of different factors. Nitrogen foliar applications can contribute toward enhancing grapevine nitrogen status and minimize the problem of leaching that traditional nitrogen-soil applications can provoke. The present study aimed to evaluate the influence of urea foliar applications on grapevine nitrogen status and grape amino acid content. Accordingly, two different doses of urea were applied over the leaves of a 'Tempranillo' vineyard. RESULTS: The highest urea doses affected nitrogen content on blade leaf tissues after veraison. Must amino acid profiles were modified by urea application and some of the compounds increased their concentrations. The effect of year on the increase of must total amino acid concentrations was more important than the effect of the doses applied. CONCLUSION: Urea foliar applications can be an interesting tool for decreasing grapevine nitrogen deficiencies. This method of nitrogen implementation in the vineyard could avoid sluggish fermentation problems during winemaking, enhance must nitrogen composition, and contribute to improving wine quality.

AB - Low levels of academic engagement may impede students' acquisition of skills. Intervening on student behavior using group contingencies may be a feasible way to increase academic engagement during group instruction. The current study examined the effect of a randomized dependent group contingency on levels of academic engagement for second-grade participants receiving small-group reading and writing instruction. The results showed that a randomized dependent group contingency increased the academic engagement of primary participants and several of the other participants during small-group instruction. The findings also showed that high levels of academic engagement were maintained when common stimuli were present and the dependent group contingency was withdrawn. PMID- 27704547 TI - Cognitive Orientation to daily Occupational Performance (CO-OP) as group therapy for children living with motor coordination difficulties: An integrated literature review. AB - BACKGROUND/AIM: Children with Developmental Coordination Disorder (DCD) demonstrate limited participation in daily occupations which negatively impacts their physical and psycho-social wellbeing. The CO-OP approach is strongly supported within the literature as an effective treatment for DCD when delivered as a one-on-one therapy. Group interventions have proven to be effective in increasing self-esteem, decreasing feelings of isolation and are a cost effective way of delivering therapy. The purpose of this review was to explore the evidence for the use of the CO-OP approach in a group format for children with motor coordination difficulties. METHODS: Searches of CINAHL, MEDLINE, Scopus, Proquest, PsycINFO, ERIC and OTDBase, were conducted from 2000 through until September 30, 2015. Articles included were in English, peer reviewed articles, followed principals of CO-OP and were delivered through a group therapy approach. All articles were critically reviewed and thematically analysed. RESULTS: 192 studies were retrieved with a final number of six articles included in the review. Six themes were highlighted: achieving a new level of perceived competence; feeling a sense of belonging; children learning how the condition affected them and strategies to overcome these challenges; careful formation of intervention groups; the value of following the CO-OP protocols; and the significance of parental involvement. CONCLUSION: The findings of this review suggest that the CO-OP approach, when administered in a group format, has the potential to benefit children living with motor coordination difficulties in both physical and psycho-social domains. More research is required to confirm these findings and contribute to evidence-based practice. PMID- 27704548 TI - Is job performance independent from career success? A conceptual distinction between competence and agency. AB - Adopting a social approach to social judgment, we conducted five studies to validate a conceptual distinction between agency and competence traits. Studies 1 3 revealed that competence traits (e.g., skillful) are associated with job performance, whereas agentic traits (e.g., ambitious) are associated with career success. Study 4 showed that only agency predicted the amount of money people are likely to earn: the more a given trait was considered as agentic, the more it was associated with high monetary values. Study 5 highlighted the predominance of agency traits over competence traits in the evaluation of an employee applying for a promotion. Nevertheless, participants asserted that competence was the main criterion they used to judge the applicant. Implications of the conceptual distinction between agency and competence for social cognition are discussed. PMID- 27704549 TI - Acute gastroenteritis outbreak associated to norovirus GI.9 in a Portuguese army base. AB - Gastroenteritis is considered a major illness within the military settings being caused by foodborne enteric pathogens that are particularly easily spread in the crowded conditions of military camps. Gastroenteritis outbreaks caused by norovirus usually affect a great number of soldiers due to the low infectious dose, copious viral shedding, and environmental stability. The present study describes the investigation of an outbreak of acute gastroenteritis that occurred in April 2015 in a Portuguese army base, focusing on the study of the epidemiological curve, symptoms experienced by the affected soldiers, and results of food, water, and stool microbiological analysis. From a total of 938 military personnel stationed on the base 46 soldiers developed acute gastroenteritis. Stool analysis of seven cases showed to be positive for norovirus GI.9 that was the probable cause of the outbreak. This report shows that genogroup I norovirus can also cause considerable morbidity in healthy young soldiers, affecting the operational effectiveness on the military forces. J. Med.

PMID- 27704550 TI - Recommended strategies for the oral administration of paediatric medicines with food and drinks in the context of their biopharmaceutical properties: a review. AB - OBJECTIVES: This review focuses on the recommended strategies for the oral administration of paediatric medicines with food in the context of their biopharmaceutical properties. KEY FINDINGS: Acceptability of oral medicines in young patients is more challenging than in adult patients. Mixing oral dosage forms with foods and drinks is sometimes suggested to administer a specific dose and enhance compliance in the paediatric population. In this review, the strategies for the co-administration of paediatric medicines with food and drinks are discussed. Current administration practices as reported by healthcare professionals and parents/carers are compared with the relevant guidelines. Differences in the type of vehicles recommended to be used and actually used in current practice were identified. Correlations of the type of food recommended, the type of formulation and the drug's biopharmaceutical classification system (BCS) class were performed and revealed that recommendations should be made on a case-by-case basis. SUMMARY: The propensity for physiochemical or bioavailability changes that may occur from the co-administration of medicines with food and drinks in the paediatric population should be considered, and harmonisation of the recommended administration strategies is needed. PMID- 27704551 TI - Challenge of paediatric compounding to solid dosage forms sachets and hard capsules - Finnish perspective. AB - OBJECTIVES: The study evaluated the quality of compounded sachets and hard gelatine capsules and their feasibility in paediatric drug administration. METHODS: Commercial tablets were compounded to sachets and capsules in hospital environment, and the uniformity of content and simulated drug dose were determined. KEY FINDINGS: Compounded formulations were successfully obtained for a range of drug substances; dipyridamole, spironolactone, warfarin and sotalol formulations were within acceptable limits for uniformity of content, in most cases. However, some loss of drug was seen. The type and amount of excipients were found to affect uniformity of content; good conformity of capsules was obtained using lactose monohydrate as filler, whereas microcrystalline cellulose was a better choice in sachets. In capsules, content uniformity was obtained for a range of drug doses. If the drug is aimed to be administered through a nasogastric tube, solubility of the drug and excipients should be considered, as they were found to affect the simulated drug dose in administration. CONCLUSIONS: Compounded sachets and capsules fulfilled the quality requirements in most cases. In compounding, the choice of excipients should be considered as they can affect conformity of the dosage form or its usability in practice. Quality assurance of compounded formulations should be taken into consideration in hospital pharmacies. PMID- 27704552 TI - I am Cait, and I am a transgender blood donor. PMID- 27704553 TI - Kelp transcriptomes provide robust support for interfamilial relationships and revision of the little known Arthrothamnaceae (Laminariales). AB - If ever there were "charismatic megaflora" of the sea, the Laminariales (kelp) would undoubtedly meet that designation. From the Northeast Pacific kelp forests to the less diverse, but nonetheless dense, kelp beds ranging from the Arctic to the cold temperate waters of the Southern Hemisphere, kelp provide habitat structure and food for a variety of productive marine systems. Consequently, kelp are well represented in the literature, however, understanding their evolution has proven challenging. We used a 152-gene phylogenomics approach to better resolve the phylogeny of the "derived" kelp families (viz., Agaraceae, Alariaceae, Laminariaceae, and Lessoniaceae). The formerly unresolved Egregia menziesii firmly joined a significantly expanded Arthrothamnaceae including Arthrothamnus, Cymathaere, Ecklonia, Macrocystis, Nereocystis, Pelagophycus, Postelsia, Pseudolessonia, Saccharina, and Streptophyllopsis, which rendered both the Laminariaceae and Lessoniaceae monogeneric. A published eight-gene alignment, the most marker-rich prior to this study, was expanded and analyzed to facilitate inclusion of Aureophycus. Although the topology was unchanged at the family level between the transcriptome data set relative to eight-gene analyses, the superior resolving power of the former was clearly established. PMID- 27704554 TI - Prediction of Clearance in Neonates and Infants (<= 3 Months of Age) for Drugs That Are Glucuronidated: A Comparative Study Between Allometric Scaling and Physiologically Based Pharmacokinetic Modeling. AB - The objective of this study was to evaluate the predictive performances of allometric models and a physiologically based pharmacokinetic model (PBPK) to predict clearance of glucuronidated drugs in neonates (<= 3 months of age). From the literature, clearance values for 9 drugs (glucuronidated) for neonates and adults were obtained. Three allometric models were used to predict clearances of these glucuronidated drugs. A PBPK model was developed using the physicochemical, biopharmaceutical, and metabolic properties together with known pediatric physiology and enzymatic ontogeny. The model was first developed for adult subjects and then verified using external data and then applied to simulations in neonates. The predictive performances of allometric and PBPK models were evaluated by comparing the predicted values of clearance with the observed clearance values in the neonates. For 9 drugs, there were 13 age groups (preterm and term neonates) for which prediction error in mean clearance values within 0.5 to 1.5-fold was observed in 10 and 11 age groups by 2 allometric models and a PBPK model, respectively. The proposed allometric methods can predict mean clearances of glucuronidated drugs in preterm and term neonates (<= 3 months of age) with reasonable accuracy (within 0.5- to 1.5-fold or 50% error) and are of practical value during neonatal drug development. The predicted mean clearance values of glucuronidated drugs in neonates <= 3 months of age by 2 allometric methods were comparable with the PBPK model. PMID- 27704556 TI - Chemistry to conservation: using otoliths to advance recreational and commercial fisheries management. AB - Otolith chemistry is an effective technique for evaluating fish environmental history, but its utility in fisheries management has not been comprehensively examined. Thus, a review of otolith chemistry with emphasis on management applicability is presented. More than 1500 otolith chemistry manuscripts published from 1967 to 2015 are reviewed and descriptive case studies are used to illustrate the utility of otolith chemistry as a fisheries management tool. Otolith chemistry publications span a wide variety of topics (e.g. natal origins, habitat use, movement, stock discrimination and statistical theory) and species in freshwater and marine systems. Despite the broad distribution of manuscripts in a variety of fisheries, environmental and ecological journals, the majority of publications (83%, n = 1264) do not describe implications or applications of otolith chemistry for fisheries management. This information gap is addressed through case studies that illustrate management applications of otolith chemistry. Case studies cover numerous topics (e.g. natal origins, population connectivity, stock enhancement, transgenerational marking, pollution exposure history and invasive species management) in freshwater and marine systems using sport fishes, invasive fishes, endangered fishes and species of commercial and aquaculture importance. Otolith chemistry has diverse implications and applications for fisheries management worldwide. Collaboration among fisheries professionals from academia, government agencies and non-governmental organizations will help bridge the research-management divide and establish otolith chemistry as a fisheries management tool. PMID- 27704557 TI - Storage characteristics of multiple-donor pooled red blood cells compared to single-donor red blood cell units. AB - BACKGROUND: Each unit of blood donated is processed and stored individually resulting in variability in the amount of red blood cells (RBCs) collected, RBC properties, and the 24-hour posttransfusion RBC survivability. As a result, each unit differs in its ability to deliver oxygen and potentially its effects on the recipient. The goal of this study was to investigate the storage of pooled RBCs from multiple donors in comparison to control standard RBC units. STUDY DESIGN AND METHODS: Two units of irradiated, leukoreduced RBCs of same ABO, D, E, C, and K antigen phenotype were collected from each of five donors using apheresis. One unit from each donor was pooled in a 2-L bag and remaining units were used as controls. After being pooled, RBCs were separated in five bags and stored at 4 degrees C along with the controls. Quality indexes were measured on Days 2, 14, and 28 for all the units. RESULTS: Adenosine triphosphate assays for both pooled and controls showed a slight decrease from Day 2 to Day 28 (pooled/control from 5.22/5.24 to 4.35/4.33 umol/g hemoglobin [Hb]). 2,3-Diphosphoglycerate was successfully rejuvenated for all RBC units on Day 28 (pooled 11.46 umol/g Hb; control 11.86 umol/g Hb). The results showed a nonsignificant difference between pooled and control units, with a general trend of lower standard deviation for pooled units when compared to controls. CONCLUSION: Pooled units have reduced unit-to-unit variability. Future exploration of their immunogenicity is required before using pooled units for transfusion.

AB - KEY POINTS: Cold water immersion and active recovery are common post-exercise recovery treatments. A key assumption about the benefits of cold water immersion is that it reduces inflammation in skeletal muscle. However, no data are available from humans to support this notion. We compared the effects of cold water immersion and active recovery on inflammatory and cellular stress responses in skeletal muscle from exercise-trained men 2, 24 and 48 h during recovery after acute resistance exercise. Exercise led to the infiltration of inflammatory cells, with increased mRNA expression of pro-inflammatory cytokines and neurotrophins, and the subcellular translocation of heat shock proteins in muscle. These responses did not differ significantly between cold water immersion and active recovery. Our results suggest that cold water immersion is no more effective than active recovery for minimizing the inflammatory and stress responses in muscle after resistance exercise. ABSTRACT: Cold water immersion and active recovery are common post-exercise recovery treatments. However, little is known about whether these treatments influence inflammation and cellular stress in human skeletal muscle after exercise. We compared the effects of cold water immersion versus active recovery on inflammatory cells, pro-inflammatory cytokines, neurotrophins and heat shock proteins (HSPs) in skeletal muscle after intense resistance exercise. Nine active men performed unilateral lower-body resistance exercise on separate days, at least 1 week apart. On one day, they immersed their lower body in cold water (10 degrees C) for 10 min after exercise. On the other day, they cycled at a low intensity for 10 min after exercise. Muscle biopsies were collected from the exercised leg before, 2, 24 and 48 h after exercise in both trials. Exercise increased intramuscular neutrophil and macrophage counts, MAC1 and CD163 mRNA expression (P < 0.05). Exercise also increased IL1beta, TNF, IL6, CCL2, CCL4, CXCL2, IL8 and LIF mRNA expression (P < 0.05). As evidence of hyperalgesia, the expression of NGF and GDNF mRNA increased after exercise (P < 0.05). The cytosolic protein content of alphaB-crystallin and HSP70 decreased after exercise (P < 0.05). This response was accompanied by increases in the cytoskeletal protein content of alphaB-crystallin and the percentage of type II fibres stained for alphaB-crystallin. Changes in inflammatory cells, cytokines, neurotrophins and HSPs did not differ significantly between the recovery treatments. These findings indicate that cold water immersion is no more effective than active recovery for reducing inflammation or cellular stress in muscle after a bout of resistance exercise. PMID- 27704558 TI - Bone Shaft Revascularization After Marrow Ablation Is Dramatically Accelerated in BSP-/- Mice, Along With Faster Hematopoietic Recolonization. AB - The bone organ integrates the activity of bone tissue, bone marrow, and blood vessels and the factors ensuring this coordination remain ill defined. Bone sialoprotein (BSP) is with osteopontin (OPN) a member of the small integrin binding ligand N-linked glycoprotein (SIBLING) family, involved in bone formation, hematopoiesis and angiogenesis. In rodents, bone marrow ablation induces a rapid formation of medullary bone which peaks by ~8 days (d8) and is blunted in BSP-/- mice. We investigated the coordinate hematopoietic and vascular recolonization of the bone shaft after marrow ablation of 2 month old BSP+/+ and BSP-/- mice. At d3, the ablated area in BSP-/- femurs showed higher vessel density (*4) and vascular volume (*7) than BSP+/+. Vessel numbers in the shaft of ablated BSP+/+ mice reached BSP-/- values only by d8, but with a vascular volume which was twice the value in BSP-/-, reflecting smaller vessel size in ablated mutants. At d6, a much higher number of Lin- (*3) as well as LSK (Lin- IL-7Ralpha Sca-1hi c-Kithi , *2) and hematopoietic stem cells (HSC: Flt3- LSK, *2) were counted in BSP-/- marrow, indicating a faster recolonization. However, the proportion of LSK and HSC within the Lin- was lower in BSP-/- and more differentiated stages were more abundant, as also observed in unablated bone, suggesting that hematopoietic differentiation is favored in the absence of BSP. Interestingly, unablated BSP-/- femur marrow also contains more blood vessels than BSP+/+, and in both intact and ablated shafts expression of VEGF and OPN are higher, and DMP1 lower in the mutants. In conclusion, bone marrow ablation in BSP /- mice is followed by a faster vascular and hematopoietic recolonization, along with lower medullary bone formation. Thus, lack of BSP affects the interplay between hematopoiesis, angiogenesis, and osteogenesis, maybe in part through higher expression of VEGF and the angiogenic SIBLING, OPN. J. Cell.

AB - BACKGROUND: Therapeutic plasma exchange (TPE) can be performed either on a membrane-based system (mTPE) or on a device that separates blood components by centrifugation (cTPE). The number of studies in this field is limited. This randomized study is the first that offers data on the membrane-based Diapact device (B. Braun Medical, Inc.) for TPE procedures and compares it to the centrifuge-based Spectra Optia (Terumo BCT, Inc.). STUDY DESIGN AND METHODS: Twenty-seven patients were enrolled in this randomized prospective head-to-head study comparing the mTPE and cTPE systems. Procedures on both devices were standardized and the plasma removal efficiency (PRE); total procedure time (including setup and priming time); and removal efficiencies of blood cells, immunoglobulin (Ig)G, and fibrinogen for all procedures were analyzed. RESULTS: While both systems removed similar amounts of plasma, it took the cTPE device a mean of 101.5 +/- 24.6 minutes to finalize a procedure that was one-third less than procedures on the mTPE device (157 +/- 26.2 min; p < 0.0001), due to a difference in PRE between the Spectra Optia (83.0% +/- 4.9%) and the Diapact (53.2% +/- 6.6%; p < 0.0001). The difference in removal efficiencies of IgG and blood cells were not significantly different but the Spectra Optia was more efficient in removing the larger fibrinogen protein than the Diapact (72.3% +/- 8.5% vs. 62.9% +/- 16.1%, respectively; p < 0.02). CONCLUSION: This study shows that, although both systems perform adequate and safe TPE procedures, those on the Spectra Optia in comparison to the Diapact are more efficient in terms of plasma removal and significantly shorter. PMID- 27704560 TI - Using complementary approaches to identify trans-domain nuclear gene transfers in the extremophile Galdieria sulphuraria (Rhodophyta). AB - Identification of horizontal gene transfers (HGTs) has primarily relied on phylogenetic tree based methods, which require a rich sampling of sequenced genomes to ensure a reliable inference. Because the success of phylogenetic approaches depends on the breadth and depth of the database, researchers usually apply stringent filters to detect only the most likely gene transfers in the genomes of interest. One such study focused on a highly conservative estimate of trans-domain gene transfers in the extremophile eukaryote, Galdieria sulphuraria (Galdieri) Merola (Rhodophyta), by applying multiple filters in their phylogenetic pipeline. This led to the identification of 75 inter-domain acquisitions from Bacteria or Archaea. Because of the evolutionary, ecological, and potential biotechnological significance of foreign genes in algae, alternative approaches and pipelines complementing phylogenetics are needed for a more comprehensive assessment of HGT. We present here a novel pipeline that uncovered 17 novel foreign genes of prokaryotic origin in G. sulphuraria, results that are supported by multiple lines of evidence including composition-based, comparative data, and phylogenetics. These genes encode a variety of potentially adaptive functions, from metabolite transport to DNA repair. PMID- 27704561 TI - Why Does Disaster Recovery Work Influence Mental Health?: Pathways through Physical Health and Household Income. AB - Disaster recovery work increases risk for mental health problems, yet the mechanisms underlying this association are unclear. We explored links from recovery work to post-traumatic stress (PTS), major depression (MD), and generalized anxiety disorder (GAD) symptoms through physical health symptoms and household income in the aftermath of the Deepwater Horizon oil spill. As part of the NIEHS GuLF STUDY, participants (N = 10,141) reported on cleanup work activities, spill-related physical health symptoms, and household income at baseline, and mental health symptoms an average of 14.69 weeks (SD = 16.79) thereafter. Cleanup work participation was associated with higher physical health symptoms, which in turn were associated with higher PTS, MD, and GAD symptoms. Similar pattern of results were found in models including workers only and investigating the influence of longer work duration and higher work-related oil exposure on mental health symptoms. In addition, longer worker duration and higher work-related oil exposure were associated with higher household income, which in turn was associated with lower MD and GAD symptoms. These findings suggest that physical health symptoms contribute to workers' risk for mental health symptoms, while higher household income, potentially from more extensive work, might mitigate risk. PMID- 27704562 TI - Efavirenz does not meaningfully affect the single dose pharmacokinetics of 1200 mg raltegravir. AB - Raltegravir is a human immunodeficiency virus (HIV)-1 integrase strand transfer inhibitor currently marketed at a dose of 400 mg twice daily (BID). Raltegravir for once daily regimen (QD) at a dose of 1200 mg (2 x 600 mg) is under development and offers a new treatment option for HIV-1 infected treatment-naive subjects. Since raltegravir is eliminated mainly by metabolism via an UDP glucuronosyltransferase (UGT) 1 A1-mediated glucuronidation pathway, co administration of UGT1A1 inducers may alter plasma levels of raltegravir. Efavirenz, an UGT1A1 inducer, was used to assess the impact of altered UGT activity on a 1200 mg QD dose of raltegravir. An open label, randomized, 2-period fixed-sequence Phase 1 study was performed in adult healthy male and female subjects (non-childbearing potential) >= 19 and <=55 years of age, with a body mass index (BMI) >= 18.5 and <=32.0 kg/m2 . Subjects (n = 21) received a single oral dose of 1200 mg raltegravir at bedtime on an empty stomach on Day 1 in Period 1. After a washout period of at least 7 days, subjects received oral doses of 600 mg efavirenz QD at bedtime for 14 consecutive days in Period 2. Subjects received a single oral dose of 1200 mg raltegravir co-administered with 600 mg efavirenz on Day 12 of Period 2. Pharmacokinetic (PK) samples were collected for 72 hours following raltegravir dosing and analyzed using a validated bioanalytical method to quantify raltegravir plasma concentrations. PK parameters were estimated using non-compartmental analysis. Administration of single 1200 mg oral doses of raltegravir alone and co-administered with multiple oral doses of efavirenz were generally well tolerated in healthy subjects. Co-administration with efavirenz yielded geometric mean ratios (GMRs) and their associated 90% confidence intervals (90% CIs) for raltegravir AUC0-infinity, Cmax , and C24 of 0.86 (0.73, 1.01), 0.91 (0.70, 1.17), and 0.94 (0.76, 1.17), respectively. The results show that efavirenz modestly reduced the exposure of raltegravir. The reduction in raltegravir exposure is not considered clinically meaningful. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - Ear is a complex system where appropriate ionic composition is essential for maintaining the tissue homeostasis and hearing function. Ion transporters and channels present in the auditory system plays a crucial role in maintaining proper ionic composition in the ear. The extracellular fluid, called endolymph, found in the cochlea of the mammalian inner ear is particularly unique due to its electrochemical properties. At an endocochlear potential of about +80 mV, signaling initiated by acoustic stimuli at the level of the hair cells is dependent on the unusually high potassium (K+ ) concentration of endolymph. There are ion channels and transporters that exists in the ear to ensure that K+ is continually being cycled into the stria media endolymph. This review is focused on the discussion of the molecular and genetic basis of previously and newly recognized ion channels and transporters that support sensory hair cell excitation based on recent knock-in and knock-out studies of these channels. This article also addresses the molecular and genetic defects and the pathophysiology behind Meniere's disease as well as how the dysregulation of these ion transporters can result in severe defects in hearing or even deafness. Understanding the role of ion channels and transporters in the auditory system will facilitate in designing effective treatment modalities against ear disorders including Meniere's disease and hearing loss.

PMID- 27704563 TI - Induction of peptidylarginine deiminase 2 and 3 by dibutyryl cAMP via cAMP-PKA signaling in human astrocytoma U-251MG cells. AB - Peptidylarginine deiminases (PADs) are posttranslational modification enzymes that citrullinate (deiminate) protein arginine residues in a calcium-dependent manner, yielding citrulline residues. Enzymatic citrullination abolishes positive charges of native protein molecules, inevitably causing significant alterations in their structure and function. Previously, we reported the abnormal accumulation of citrullinated proteins and an increase of PAD2 content in hippocampi of patients with Alzheimer disease. In this study, we investigated PAD expression by using dibutyryl cAMP (dbcAMP) in human astrocytoma U-251MG cells. Under normal culture conditions, PAD2 and PAD3 mRNA expression is detectable with quantitative PCR in U-251MG cells. The addition of dbcAMP in a dose-dependent manner significantly increased this mRNA expression and protein levels. Moreover, PAD enzyme activity also increased significantly and dose-dependently. Furthermore, the expression of PAD2 and PAD3 mRNA was inhibited by the cAMP dependent PKA inhibitor KT5720, suggesting that such expression of dbcAMP-induced PAD2 and PAD3 mRNA is mediated by the cAMP-PKA signaling pathway in U-251MG cells. This is the first report to document the PAD2 and PAD3 mRNA expression induced by dbcAMP and to attribute the induction of these genes to mediation by the cAMP-PKA signaling pathway in U-251MG cells.

AB - BACKGROUND: This literature review investigates what research reports about the contribution that communities of practice (CoPs) can make in the continuing professional development (CPD) of qualified occupational therapists. METHODS: Academic databases (CINAHL, MEDLINE and ERIC) were searched and articles were included based on pre-determined criteria. Five articles were included in the review. RESULTS: The CoPs in the reviewed articles provided opportunities for knowledge sharing, knowledge translation, reflection on action and learning through boundary crossing. The presence of professionals with diverse perspectives was an important ingredient that facilitated CPD. CONCLUSION: Research into the use of CoPs in occupational therapy is sparse. CoPs could provide a CPD forum for occupational therapists whether online or face to face. Practitioners are encouraged to participate in CoPs. Further research into the use of CoPs is recommended.

Fairbairn believed that the psychoanalyst's motivations and theories must ultimately be rooted in a need to resolve personal conflicts. His self analytic and other records, now publicly available, indicate how his struggles with unacceptable sexual feelings and their symptomatic manifestations affected not only his theorizing, especially about sexuality, but also his clinical practice, as well as his personal and family life. Fairbairn's case affords a unique opportunity to document the effects of homophobia in a major psychoanalyst. PMID- 27704567 TI - PSYCHOANALYSIS IN CHINA: AN ESSAY ON THE RECENT LITERATURE IN ENGLISH. AB - Using extensive quotation, the author reviews the introduction and current state of psychoanalysis and psychoanalytic psychotherapy in China from the vantage point of recent publications in English. Psychoanalysis was briefly introduced to China before the Communist era, then forbidden, and has experienced an accelerated reintroduction since the late 1980s. The author briefly summarizes the cultural and historical background of China relevant to the introduction of psychoanalysis, the traumatic history of China, and the deep structure of thought and philosophical differences from Western culture that challenge a simple imposition of psychoanalytic ideas and practice, and some psychological effects of rapid cultural change throughout China. Training programs in China, the general enthusiasm for analysis among the Chinese, and a number of notable contributions by Western and Chinese authors are discussed. Also surveyed are the use of distance technology for training and treatment, the personal experience of Chinese senior and junior colleagues, and ongoing challenges to the continuing growth of psychoanalysis and analytic psychotherapy in China.

AB - This paper describes the shift that appears to be taking place in contemporary psychoanalysis, as reflected among intersubjective approaches, from a monological conception of the self to a dialogical one. The monological self emphasizes the separation between mind, body, and external world, focusing on the representational and descriptive/referential function of language. In contrast, the dialogical self emphasizes practices, the permeable nature of relationships between subjects, and the constitutive function of language. This paper attempts to explain the growing emphasis on the dialogical self, understood from a theoretical, metatheoretical, and technical point of view, using contemporary intersubjective approaches to illustrate this shift.

AB - OBJECTIVES: We evaluated the hypolipidaemic effect of mannan Candida albicans serotype A, relative to atorvastatin, in a mouse model of hyperlipidaemia. METHODS: Mannan serotype A was investigated in vitro and in vivo to determine its effects on macrophage proliferation, nitric oxide (NO) production by cultured macrophages, serum and liver lipids, changes in liver morphology and serum chitotriosidase activity and its expression in the liver. KEY FINDINGS: Mannan serotype A stimulates the macrophage proliferation and NO production in murine peritoneal macrophages in vitro. The activity of serum chitotriosidase (an enzyme released from the activated macrophages) was found to be significantly increased in P-407-induced hyperlipidaemic mice pretreated with low-dose mannan compared with mice administered P-407 only. Mannan treatment in mice was shown to significantly increase the chitotriosidase expression in the liver of both non hyperlipidaemic and P-407-induced hyperlipidaemic mice. Lastly, mice pretreated with mannan before the induction of hyperlipidaemia with P-407 showed a significant reduction in the serum concentration of atherogenic LDL cholesterol, total cholesterol, triglycerides and liver triglycerides. CONCLUSIONS: It is suggested that mannan serotype A, like beta-glucan, may represent another hypolipidaemic agent, which could potentially be used as an adjunctive therapy with conventional antihyperlipidaemic drugs (statins and fibrates) in humans.

AB - Unbiased, deep sequencing of a nasal specimen from an otherwise healthy 13-month old boy hospitalized in intensive care revealed high gene expression and the complete genome of a novel isolate of KI polyomavirus (KIPyV). Further investigation detected minimal gene expression of additional viruses, suggesting that KIPyV was potentially the causal agent. Analysis of the complete genome of isolate NMKI001 revealed it is different from all previously reported genomes and contains two amino acid differences as compared to the closest virus isolate, Stockholm 380 (EF127908).

PMID- 27704586 TI - Hypermethylation of PRDM1/Blimp-1 promoter in extranodal NK/T-cell lymphoma, nasal type: an evidence of predominant role in its downregulation. AB - The loss of PRDM1 expression is common in extranodal NK/T-cell lymphoma, nasal type (EN-NK/T-NT), but the role of promoter methylation in silencing PRDM1 expression remains unclear. Hence, we performed pyrosequencing analysis to evaluate the promoter methylation of PRDM1 gene in vivo and in vitro, to analyze the association between methylation and its expression, and to assess cellular effects of PRDM1 reexpression. The promoter hypermethylation of PRDM1 gene was detected in 11 of 25 EN-NK/T-NT cases (44.0%) and NK92 and NKL cells. The promoter hypermethylation of PRDM1 was significantly correlated with PRDM1 expression in vivo and in vitro, predominantly contributing to the loss of PRDM1 expression compared with genetic deletion and aberrant expression of miR-223 in EN-NK/T-NT. PRDM1 expression was significantly restored by demethylation treatment, which induced cell proliferation suppression, cell cycle arrest, and apoptosis increase. We also found that PRDM1 reexpression could downregulate the expression of Ets-1, T-bet, granzyme B, and c-myc. Our findings demonstrated that the promoter hypermethylation of PRDM1 harbored a predominant role in the downregulation of PRDM1 expression, significantly affecting the biological behavior of tumor cells in EN-NK/T-NT. PMID- 27704587 TI - Postdeployment Suicide Risk Increases Over a 6-month Period: Predictors of Increased Risk among Midwestern Army National Guard Soldiers. AB - National Guard (NG) soldiers returning from deployments in Iraq and Afghanistan were surveyed at 6 and 12 months following their return (N = 970). The overall prevalence of suicide risk at 6 and 12 months following their return was assessed, as were changes in suicide risk among soldiers initially at high or low risk. Factors associated with changes in risk were assessed. The percentage of NG soldiers with high suicide risk increased from 6.8% at 6 months to 9.2% at 12 months (odds ratio = 1.7, p = .02). In the 882 soldiers initially at low risk, 5.9% (52/882) became high risk at 12 months; in the 64 soldiers initially at high risk, 46.9% (30/64) became low risk at 12 months. Initial levels of depressive symptoms were predictive of changing to high risk; this association appeared to be partially explained by soldier reports of increased search in the meaning in life and higher levels of perceived stress. Because suicide risk increases over the first 12 months, continued risk assessments during this time period should be considered. Supporting soldiers to find meaning in their life after deployment and enhancing their capacity to cope with perceived stress may help prevent increases in suicide risk over time. PMID- 27704588 TI - Assessment of Web-based education resources informing patients about stroke prevention in atrial fibrillation. AB - WHAT IS KNOWN AND OBJECTIVE: The importance of 'shared decision-making' is much emphasized in recent clinical guidelines regarding stroke management in atrial fibrillation (AF), more so following the inclusion of non-vitamin K oral anticoagulants (NOACs) among the treatment options. It is important that patients are navigated through balanced and unbiased information about the available treatment options, so as to understand the risk and benefits associated with the therapies, and to enable them to accordingly communicate their concerns and views with their clinicians prior to therapy selection. Given the increasing popularity of the Internet as a source of health information, the specific objectives of this study were to identify what aspects of thromboprophylaxis (antithrombotic treatment options) were most commonly described in these resources, both in terms of content, that is to report the information provided (quantitative) and the underlying themes underpinning this content, and in terms of how this information might guide patient preferences (qualitative). METHOD: Resources for patients were identified via online search engines (Google, Yahoo, Ask, Bing), using the terms 'atrial fibrillation' and 'stroke' combined with patient/consumer information, patient/consumer resources and patient/consumer education. The researchers employed pragmatic (mix-method) approach to analyse the information presented within the resources using manual inductive coding, at two levels of analysis: manifest (reported surface theme or codes that are obvious and are countable) and latent (thematic, interpretative presentation of the content in the data set). RESULTS AND DISCUSSION: In total, 33 resources were reviewed. The 'manifest-level' analysis found that warfarin was the most frequently mentioned thromboprophylactic option among the anticoagulants, being cited in all resources, followed by the NOACs - dabigatran (82.3% of resources), rivaroxaban (73.5%) and apixaban (67.6%). Only one-third of resources discussed the role of stroke risk and/or bleeding risk within the decision-making. At the 'latent level' analysis, three overarching themes emerged: (i) The practical ease of managing NOACs over warfarin; (ii) Unbalanced explanation about stroke risk versus bleeding risk; and (iii) Individualized antithrombotic therapy selection. In general, the benefit of stroke prevention with anticoagulant use was emphasized less compared to the risk of bleeding. Overall, one in four resources had an implied preference for either warfarin or the NOACs. WHAT IS NEW AND CONCLUSION: The implied inclination of some resources towards particular anticoagulant therapies and imbalanced information about the importance of anticoagulation in AF might misinform and confuse patients. Patients' engagement in shared decision-making and adherence to medicines may be undermined by the suboptimal quality of information provided in the resources. Health professionals have an important role to play in referring patients to appropriate resources to enable patient engagement in shared decision-making when selecting treatment. PMID- 27704589 TI - Identifying research priorities with nurses at a tertiary children's hospital in the United Kingdom. AB - AIM: The objective of this study was to undertake a research priority setting exercise with the aim of maximizing efficiency and impact in research activity undertaken by nurses at one children's tertiary healthcare institution by ensuring the clinical staff directly shaped a coherent, transparent and consensus driven nurse-led research agenda. BACKGROUND: In Round 1, the research topics of 147 nurses were elicited using a modified nominal group technique as the consensus method. The number of participants in the 24 separate discussions ranged from 3 to 21, generating lists of between 6 and 23 topics. In Round 2, nurses from the clinical areas ranked topics of importance resulting in a set of four to five priorities. In Round 3, the divisional heads of nursing consulted with staff in all of their clinical areas to each finalize their five divisional priorities. The Nursing Research Working Group discussed and refined the divisions' priorities and voted on the final list to agree the top five research priorities for the organization. RESULTS: A total of 269 research topics were initially generated. Following three rounds of ranking and prioritizing, five priorities were agreed at Divisional level, and from these, the five top organizational priorities were selected. These were (i) understanding and improving all aspects of the patient journey through the hospital system; (ii) play; (iii) staff wellbeing, patient care and productivity; (iv) team work - linking to a more efficient service; and (v) supporting parents/parent pathway. CONCLUSIONS: Divisional priorities have been disseminated widely to clinical teams to inform a patient-specific nurse-led research agenda. Organizational priorities agreed upon have been disseminated through management structures and processes to ensure engagement at all levels. A subgroup of the Nursing Research Working Group has been delegated to take this work forward so that the agreed priorities continue to contribute towards shaping nurse-led research activity, thereby going some way to inform and embed an evidence-based culture of inquiry.

AB - BACKGROUND: Early risk factors for poor child outcomes are well established, and some group parenting programmes have demonstrated good outcomes for children under 3 years of age. This randomized controlled trial evaluated the effectiveness of the Incredible Years(r) Toddler Parenting Programme with parents of 1-year-old and 2-year-old children recruited by staff in disadvantaged Flying Start areas across Wales. METHODS: Eighty-nine families with a child aged between 12 and 36 months at baseline participated in a pragmatic community-based trial of the programme in eight Flying Start areas. Outcomes were measured at baseline, 6 months and 12 months using measures of parental mental health, competence, child behaviour, child development, home environment and blinded-observation of parent child interactions. RESULTS: Significant intervention group improvements were found in parental mental well-being and observed praise at 6 months. Significant improvements for the intervention group at 12 months included child development, home environment and parental depression. CONCLUSION: The study provides preliminary evidence for programme attendance.

AB - Emerging viruses such as Ebola virus (EBOV), Lassa virus (LASV), and avian influenza virus H5N1 (AIV) are global health concerns. Since there is very limited options (either vaccine or specific therapy) approved for humans against these viruses, there is an urgent need to develop prophylactic and therapeutic treatments. Previously we reported a high-throughput screening (HTS) protocol to identify entry inhibitors for three highly pathogenic viruses (EBOV, LASV, and AIV) using a human immunodeficiency virus-based pseudotyping platform which allows us to perform the screening in a BSL-2 facility. In this report, we have adopted this screening protocol to evaluate traditional Chinese Medicines (TCMs) in an effort to discover entry inhibitors against these viruses. Here we show that extracts of the following Chinese medicinal herbs exhibit potent anti-Ebola viral activities: Gardenia jasminoides Ellis, Citrus aurantium L., Viola yedoensis Makino, Prunella vulgaris L., Coix lacryma-jobi L. var. mayuen (Roman.) Stapf, Pinellia ternata (Thunb.) Breit., and Morus alba L. This study represents a proof-of-principle investigation supporting the suitability of this assay for rapid screening TCMs and identifying putative entry inhibitors for these viruses. J. Med.

AB - For dose-response analysis in quantitative microbial risk assessment (QMRA), the exact beta-Poisson model is a two-parameter mechanistic dose-response model with parameters alpha>0 and beta>0, which involves the Kummer confluent hypergeometric function. Evaluation of a hypergeometric function is a computational challenge. Denoting PI(d) as the probability of infection at a given mean dose d, the widely used dose-response model PI(d)=1-(1+dbeta)-alpha is an approximate formula for the exact beta-Poisson model. Notwithstanding the required conditions alpha<>1, issues related to the validity and approximation accuracy of this approximate formula have remained largely ignored in practice, partly because these conditions are too general to provide clear guidance. Consequently, this study proposes a probability measure Pr(0 < r < 1 | alpha, beta) as a validity measure (r is a random variable that follows a gamma distribution; alpha and beta are the maximum likelihood estimates of alpha and beta in the approximate model); and the constraint conditions beta>(22alpha)0.50 for 0.020.99) . This validity measure and rule of thumb were validated by application to all the completed beta-Poisson models (related to 85 data sets) from the QMRA community portal (QMRA Wiki). The results showed that the higher the probability Pr(0 < r < 1 | alpha, beta), the better the approximation. The results further showed that, among the total 85 models examined, 68 models were identified as valid approximate model applications, which all had a near perfect match to the corresponding exact beta-Poisson model dose-response curve. PMID- 27704593 TI - Design of clinical trials involving multiple hypothesis tests with a common control. AB - Randomized clinical trials comparing several treatments to a common control are often reported in the medical literature. For example, multiple experimental treatments may be compared with placebo, or in combination therapy trials, a combination therapy may be compared with each of its constituent monotherapies. Such trials are typically designed using a balanced approach in which equal numbers of individuals are randomized to each arm, however, this can result in an inefficient use of resources. We provide a unified framework and new theoretical results for optimal design of such single-control multiple-comparator studies. We consider variance optimal designs based on D-, A-, and E-optimality criteria, using a general model that allows for heteroscedasticity and a range of effect measures that include both continuous and binary outcomes. We demonstrate the sensitivity of these designs to the type of optimality criterion by showing that the optimal allocation ratios are systematically ordered according to the optimality criterion. Given this sensitivity to the optimality criterion, we argue that power optimality is a more suitable approach when designing clinical trials where testing is the objective. Weighted variance optimal designs are also discussed, which, like power optimal designs, allow the treatment difference to play a major role in determining allocation ratios. We illustrate our methods using two real clinical trial examples taken from the medical literature. Some recommendations on the use of optimal designs in single-control multiple comparator trials are also provided. PMID- 27704594 TI - l-arginine and l-NMMA for assessing cerebral endothelial dysfunction in ischaemic cerebrovascular disease: A systematic review. AB - Endothelial dysfunction (ED), in particular cerebral ED, may be an essential biomarker for ischaemic cerebrovascular disease. However, there is no consensus on methods to best estimate cerebral ED. In this systematic review, we evaluate the use of l-arginine and NG -monomethyl-l-arginine (l-NMMA) for assessment of cerebral ED. A systematic search of PubMed, EMBASE and the Cochrane Library was done. We included studies investigating cerebrovascular response to l-arginine or l-NMMA in human subjects with vascular risk factors or ischaemic cerebrovascular disease. Seven studies (315 subjects) were eligible according to inclusion and exclusion criteria. Studies investigated the effect of age (n=2), type 2 diabetes mellitus (DM) (n=1), cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) (n=1), leukoaraiosis (n=1), and prior ischaemic stroke or transient ischaemic attack (TIA) (n=2) on cerebral ED. Most studies applied transcranial Doppler to quantify cerebral ED. Endothelium dependent vasodilatation (EDV) induced by l-arginine was impaired in elderly and subjects with leukoaraiosis, but enhanced in CADASIL patients. Studies including subjects with prior ischaemic stroke or TIA reported both enhanced and impaired EDV to l-arginine. Responses to l-NMMA deviated between subjects with type 2 DM and the elderly. We found only few studies investigating cerebral endothelial responses to l-arginine and l-NMMA in subjects with vascular risk factors or ischaemic cerebrovascular disease. Inconsistencies in results were most likely due to variations in methods and included subject populations. In order to use cerebral ED as a prognostic marker, further studies are required to evaluate the association to cerebrovascular disease. PMID- 27704596 TI - A vocational rehabilitation intervention for young adults with physical disabilities: participants' perception of beneficial attributes. AB - BACKGROUND: Finding and maintaining employment is a major challenge for young adults with physical disabilities and their work participation rate is lower than that of healthy peers. This paper is about a program that supports work participation amongst young adults with chronic physical disabilities. The study aims to explore their experienced barriers and facilitators for finding and maintaining employment after starting this program, the participant-perceived beneficial attributes of the program and participants' recommendations for additional intervention components. METHODS: Semi-structured interviews (n = 19) were held with former intervention participations. Interviews were recorded and transcribed ad verbatim. Themes were derived using the phenomenological approach. RESULTS: Physical functions and capacities, supervisor's attitude, self-esteem and self-efficacy and openness and assertiveness were experienced barriers and facilitators for finding and maintaining employment. Improvement of self promoting skills and disclosure skills through job interview-training, increased self-esteem or self-efficacy through peer-support, a suitable job through job placement, improvement of work ability through arrangement of adjusted work conditions and change of supervisor's attitude through education provided to the supervisor were perceived as beneficial attributes of the intervention. Respondents recommended to incorporate assertiveness and openness skills training into future intervention programs. CONCLUSIONS: The findings suggest that programs supporting work participation should be designed to provide challenging, real-world experiential opportunities that provide young adults with physical disabilities with new insights, self-efficacy and life skills. Also, such programs should facilitate context centered learning. Former intervention participants, therefore, evaluated job-interview training, sharing learning and social experiences with peers, job placement, arrangement of adjusted work conditions and education as beneficial attributes of the 'At Work' program. In addition, they recommended, to incorporate more training on assertiveness and disclosure. We advise professionals to include these beneficial attributes in similar interventions in other contexts. PMID- 27704595 TI - Cholinergic regulation of fear learning and extinction. AB - Cholinergic activation regulates cognitive function, particularly long-term memory consolidation. This Review presents an overview of the anatomical, neurochemical, and pharmacological evidence supporting the cholinergic regulation of Pavlovian contextual and cue-conditioned fear learning and extinction. Basal forebrain cholinergic neurons provide inputs to neocortical regions and subcortical limbic structures such as the hippocampus and amygdala. Pharmacological manipulations of muscarinic and nicotinic receptors support the role of cholinergic processes in the amygdala, hippocampus, and prefrontal cortex in modulating the learning and extinction of contexts or cues associated with threat. Additional evidence from lesion studies and analysis of in vivo acetylcholine release with microdialysis similarly support a critical role of cholinergic neurotransmission in corticoamygdalar or corticohippocampal circuits during acquisition of fear extinction. Although a few studies have suggested a complex role of cholinergic neurotransmission in the cellular plasticity essential for extinction learning, more work is required to elucidate the exact cholinergic mechanisms and physiological role of muscarinic and nicotinic receptors in these fear circuits. Such studies are important for elucidating the role of cholinergic neurotransmission in disorders such as posttraumatic stress disorder that involve deficits in extinction learning as well as for developing novel therapeutic approaches for such disorders.

AB - The study goal was to determine whether a significant number of high suicide risk individuals would confidentially put their own names onto a list to prevent future gun purchases. An anonymous written survey was administered in an inpatient psychiatric unit and two outpatient psychiatric clinics at an academic medical center. Two hundred forty individuals were approached to fill out the survey, of whom 200 (83.3%) did so. Forty-six percent of participants stated that they would put their own name onto the list. This novel suicide prevention proposal, a Do-Not-Sell List, would appeal to many people at high risk for suicide. PMID- 27704598 TI - Identification of sequence polymorphisms in the displacement loop region of mitochondrial DNA as a risk factor for gastroenteropancreatic neuroendocrine neoplasm. AB - BACKGROUND: Gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) are relatively rare tumors that arise from the diffuse neuroendocrine system, and the biggest advances in molecular biology have helped in understanding these biological diversity of tumors over the past decades. It is important to determine the carcinogenesis of GEP-NEN from the perspective of genetic backgrounds. METHODS: Mitochondrial DNA (mtDNA) of peripheral blood from 66 GEP NEN patients and from 75 healthy controls without history of any cancer were examined for single nucleotide polymorphisms (SNPs) and mutations in the displacement loop (D-loop) region. RESULTS: Single nucleotide polymorphisms were detected in 148 sites within the 982 bp mitochondria D-loop region from blood samples of healthy controls and GEP-NEN patients. SNPs with a rare allele frequency >5% in either controls or GEP-NEN patients were used for cancer risk analysis; a total of 23 SNPs were selected. When individual SNPs of GEP-NEN patients compared with healthy controls were analyzed, a statistically significant increase in the SNP frequency was observed for 73G, 150T, 151T, 492C, 16257A, 16261T, and 16399G in GEP-NEN patients (P<.05). It was also observed that the SNP frequency for 489C and 16519C significantly decreased in GEP-NEN patients compared with controls (P<.05). CONCLUSION: In summary, SNPs in the mutations of the mitochondrial D-loop may be valuable markers for GEP-NEN risk evaluation. Analysis of the genetic polymorphisms in the D-loop may be useful for diagnosis of high-risk individuals. PMID- 27704599 TI - A zero-augmented generalized gamma regression calibration to adjust for covariate measurement error: A case of an episodically consumed dietary intake. AB - Measurement error in exposure variables is a serious impediment in epidemiological studies that relate exposures to health outcomes. In nutritional studies, interest could be in the association between long-term dietary intake and disease occurrence. Long-term intake is usually assessed with food frequency questionnaire (FFQ), which is prone to recall bias. Measurement error in FFQ reported intakes leads to bias in parameter estimate that quantifies the association. To adjust for bias in the association, a calibration study is required to obtain unbiased intake measurements using a short-term instrument such as 24-hour recall (24HR). The 24HR intakes are used as response in regression calibration to adjust for bias in the association. For foods not consumed daily, 24HR-reported intakes are usually characterized by excess zeroes, right skewness, and heteroscedasticity posing serious challenge in regression calibration modeling. We proposed a zero-augmented calibration model to adjust for measurement error in reported intake, while handling excess zeroes, skewness, and heteroscedasticity simultaneously without transforming 24HR intake values. We compared the proposed calibration method with the standard method and with methods that ignore measurement error by estimating long-term intake with 24HR and FFQ-reported intakes. The comparison was done in real and simulated datasets. With the 24HR, the mean increase in mercury level per ounce fish intake was about 0.4; with the FFQ intake, the increase was about 1.2. With both calibration methods, the mean increase was about 2.0. Similar trend was observed in the simulation study. In conclusion, the proposed calibration method performs at least as good as the standard method. PMID- 27704600 TI - Reply to 'Endpoints in strategies to reduce polypharmacy'.

AB - Diet is an important pathway for metal uptake in marine organisms, and assimilation efficiency is one of the most relevant parameters to quantify trophic transfer of metals along aquatic food webs. The most commonly used method to estimate this parameter is pulse-chase feeding using radiolabeled food. This approach is, however, based on several assumptions that are not always tested in an experimental context. The present study aimed to validate the approach by assessing single-feeding and multiple-feeding approaches, using a model species (the turbot Scophthalmus maximus). Using the kinetic data obtained from the single-feeding experiment, the reconstruction of a multi-feeding experiment was tested for consistency with data provided by an actual multi-feeding performed under the same experimental conditions. The results validated the single-feeding approach. Environ Toxicol Chem 2017;36:1227-1234. (c) 2016 SETAC. PMID- 27704603 TI - Novel potential marker for native anteversion of the proximal femur. AB - Identifying native femoral version from proximal femoral landmarks would be of benefit both for preoperative assessment as well as intraoperatively. To identify potential markers for femoral anteversion, an empirical framework was developed for orientation-independent analysis of the proximal femur from pelvic CT to allow for segmentation of the proximal femur into five constituent regions: Femoral head, femoral neck, greater trochanter, lesser trochanter and femoral shaft. The framework is based on the identification of differences in the radius of curvature at anatomic zones of transition between regions of the proximal femur, followed by non-linear geometric shape fitting. The framework is applied to 86 proximal femurs segmented from pelvic CTs, with at least 2 cm of proximal femur remaining below the lesser trochanter, obtained for non-musculoskeletal pathology to investigate potential proximal femoral markers for native femoral version. The analysis of the proximal femur suggests a fixed relationship between the maximal femoral canal diameter 1 cm proximal to the base of the lesser trochanter from the center of the greater trochanter and the femoral neck axis of 4.13 degrees +/- 4.99 degrees . Further full-length femoral studies are needed to confirm the relationship of the maximal canal diameter as a proxy for native femoral anteversion. Published by Wiley Periodicals, Inc.

AB - Implant-associated osteomyelitis (IAO) is a common complication in orthopedic surgery. The aim of this study was to elucidate how deep IAO can go into the peri implanted bone tissue within a week. The study was performed in a porcine model of IAO. A small steel implant and either 104 CFU/kg body weight of Staphylococcus aureus or saline was inserted into the right tibial bone of 12 pigs. The animals were consecutively killed on day 2, 4 and 6 following implantation. Bone tissue around the implant was histologically evaluated. Identification of S. aureus was performed immunohistochemically on tissue section and with scanning electron microscopy and peptide nucleic acid in situ hybridization on implants. The distance of the peri-implanted pathological bone area (PIBA), measured perpendicular to the implant, was significantly larger in infected animals compared to controls (p = 0.0014). The largest differences were seen after 4 and 6 days of inoculation, where PIBA measurements of up to 6 mm were observed. Positive S. aureus bacteria were identified on implants and from 25 MUm to 6 mm into PIBA. This is important knowledge for optimizing outcomes of surgical debridement in osteomyelitis. PMID- 27704605 TI - Granulomatous and lymphocytic hypophysitis - are they immunologically distinct? AB - Hypophysitis includes three histopathologically distinct entities - granulomatous, lymphocytic and xanthomatous forms. Etiopathogenesis and the immunological differences among these is not well characterized. This study aims to explore the immunopathogenesis of granulomatous and lymphocytic forms of hypophysitis. Demographic, clinical, endocrine function and radiological features of 33 histologically confirmed cases of hypophysitis were reviewed. Immunophenotyping of inflammatory component was performed in 13/33 cases. Visual disturbances (46%), headache (36%), polyuria/polydipsia (6%), menstrual disturbance (6%) and galactorrhoea (6%) were the frequent presenting symptoms. Endocrine abnormalities were noted in 11/18 cases evaluated (61%). Hypothyroidism was the most common endocrine abnormality (33.33%) followed by hyperprolactinaemia (22%) and hypocortisolism (16.66%). On neuroimaging, sellar mass with variable contrast enhancement was observed. On histology, granulomatous hypophysitis (GH) was more common (84.84%) than lymphocytic hypophysitis (LH) (15.15%). In GH, the infiltrate had almost equal proportions of CD3+ T cells and CD68+ histiocytes. Cytotoxic T cells (CD8+) predominated [CD4:CD8 < 1]. CD20+ B cell component ranged from <5% to 50%. Fibrosis, necrosis and giant cells accompanied GH. LH in contrast, had CD4+ T-helper cell predominance [CD4: CD8 > 1]. CD68+ histiocytes constituted <20% and CD20+ B cells, 5-40% of the infiltrates. In conclusion, GH revealed cytotoxic T cell and histiocyte rich infiltrate in contrast to CD4+ T-cell predominance in LH suggesting that the two forms have distinct immunological mechanisms in evolution, an autoimmune process in LH and type IV hypersensitivity response in GH. PMID- 27704606 TI - Donor nerve sources in free functional gracilis muscle transfer for elbow flexion in adult brachial plexus injury. AB - BACKGROUND: With complete plexus injuries or late presentation, free functional muscle transfer (FFMT) becomes the primary option of functional restoration. Our purpose is to review cases over a 10-year period of free functioning gracilis muscle transfer after brachial plexus injury to evaluate the effect of different donor nerves used to reinnervate the FFMT on functional outcome. METHODS: A retrospective study from April 2001 to January 2011 of a single surgeon's practice was undertaken. During this time period 22 patients underwent FFMT at Washington University in St Louis, Missouri for elbow flexion. RESULTS: Thirteen patients for whom FFMT was performed for elbow flexion met all of the requirements for inclusion in this study. Average time from injury to first operation was 12.8 months (range 4-60), and average time from injury to FFMT was 29 months (range 8-68). Average follow-up was 31.8 months (range 11-84). The nerve donors utilized included the distal accessory nerve, intercostal with or without rectus abdominis nerves, medial pectoral nerves, thoracodorsal nerve, and flexor carpi ulnaris fascicle of ulnar nerve. Functional recovery of elbow flexion was measured using the MRC grading system which showed 1 M5/5, 5 M4, 4 M3, and 3 M2 outcomes. CONCLUSION: Intraplexal donor motor nerves if available will provide better transferred muscle function because they are higher quality donors closer to the muscle and can be done in one stage without a nerve graft. Otherwise, intercostal, rectus abdominis, or the distal accessory nerve should be used in a staged fashion. (c) 2016 Wiley Periodicals, Inc. Microsurgery 37:377 382, 2017. PMID- 27704608 TI - Direct thrombectomy as a salvage technique in free flap breast reconstruction. AB - BACKGROUND: Breast reconstruction with microvascular free tissue transfer has become a widely used method. Despite a high rate of success, a compromised flap necessitating re-exploration can occur. Here, we introduce direct thrombectomy as a flap salvage technique, and compared the results with conventional thrombectomy. METHODS: A total of 488 patients who underwent breast reconstruction using a free transverse rectus abdominis myocutaneous flap between March 2009 and February 2014 were retrospectively analyzed. Flap salvage was conducted by either conventional thrombectomy using a Fogarty catheter, or direct thrombectomy via either a side branch or additional incisions at the stump of the main pedicle at the distal end of the thrombus. RESULTS: Flap compromise necessitating re-exploration due to extensive pedicle thrombosis was identified in 30 patients (6.1%). Direct thrombectomy was used in 9 patients, and conventional thrombectomy in 21 patients. Direct thrombectomy had a significantly higher success rate of flap salvage than conventional thrombectomy (88.9% vs. 47.6%; P = .049). CONCLUSIONS: In the event of vascular thrombosis after free flap breast reconstruction, direct thrombectomy at the proximal pedicle stump beside the anastomosis opening appears to be an effective and reliable option that minimizes vessel trauma related to conventional catheter use.

AB - Backswimmers (Hemiptera: Heteroptera: Notonectidae) are insect predators in a wide variety of freshwater habitats. These insects are well known through their role as mosquito biocontrol agents, their ability to prey on immature fishes and frogs, and because they are often the first to colonize aquatic habitats. As a consequence, these predators may face intended or unintended insecticide exposures that may lead to death or to impairment of essential behaviors (e.g., swimming and position in the water column). The toxicity of deltamethrin (a type II pyrethroid insecticide stressor) and the swimming activity of the backswimmers Buenoa tarsalis and Martarega bentoi were evaluated. Concentration-mortality and survival bioassays were conducted with the insecticide, which were compared with controls without deltamethrin. Deltamethrin was 26-fold more toxic to B. tarsalis (median lethal concentration [LC50] = 4.0 ng a.i./L) than to M. bentoi (LC50 = 102.5 ng a.i./L). The pattern of occupation of B. tarsalis, but not of M. bentoi, in the water column was also disrupted, and B. tarsalis was forced to stay near the water surface longer with exposure to deltamethrin. Thus, based on the findings, B. tarsalis was less resilient to deltamethrin exposure compared with M. bentoi, and the efficacy of swimming-dependent processes might be negatively affected (e.g., prey catching, partner encounter, and antipredator behaviors) for B. tarsalis under deltamethrin exposure.

PMID- 27704609 TI - The free medial sural artery perforator flap: Versatile option for soft tissue reconstruction in small-to-moderate size defects of the foot and ankle. AB - BACKGROUND: The medial sural artery perforator (MSAP) flap shows advantages for reconstruction in the foot and ankle, where bulk is a liability. We evaluated the versatility of this flap and provide further evidence on its use for covering small-to-moderate size defects by comparing the outcome depending on the region of reconstruction. METHODS: Twenty-two patients with variable defects of 4 * 4 to 18 * 7 cm underwent MSAP flap reconstruction. Final outcomes of all patients were evaluated 12-months postoperatively using the AOFAS ankle-hindfoot, midfoot and hallux scale for clinical-functional evaluation, and the SF-36 health survey for quality-of-life measurement. The scores were compared in three groups according to the anatomic region of MSAP flap reconstruction. RESULTS: The flap size ranged between 6 * 4 and 21 * 9 cm. One venous congestion was salvaged by venous thrombectomy and reanastomosis, and one marginal flap necrosis healed by secondary intention. All flaps survived, and all patients returned to ambulation. Patients with reconstruction of the ankle-hindfoot or hallux showed significantly lower AOFAS ankle-hindfoot (P = 0.021) or hallux scores (P = 0.034), whereas reconstruction of the midfoot led to equal AOFAS midfoot scores (P = 0.265) as compared with patients without reconstruction in the respective region. Comparison of SF-36 physical (P = 0.936) and mental (P = 0.855) scores of all three regions remained insignificant. CONCLUSION: The MSAP flap provides thin soft tissue coverage, enabling good functional recovery after defect reconstruction all around the foot and ankle, with evident advantages in the midfoot. However, the functional outcomes after reconstruction of the ankle hindfoot or hallux region depend on the preexistent functional impairment. PMID- 27704611 TI - Variation in taper surface roughness for a single design effects the wear rate in total hip arthroplasty. AB - Material loss from the head-stem taper junction of total hip arthroplasty (THA) is implicated in adverse reactions to metal debris (ARMD); the mechanisms for this are multi-factorial. We investigated the relationship between the roughness of the "as manufactured" taper surface and the wear rate from this junction. Fifty retrieved Pinnacle metal-on-metal (MOM) bearings paired with a Corail stem were included in the study. Multivariable statistical analysis was performed to determine the influence of taper roughness on material loss rate after controlling for other confounding surgical, implant, and patient factors. The surface roughness of the "as manufactured" head taper surface was associated with the rate of material loss from this surface. Four of eighteen roughness variables taken from ISO 4,287 and ISO 13,565-2 were significant: The Reduced Peak Height (Rpk, the protruding peaks above the core) (p = 0.004), Material Ratio 1 (Mr1, the ratio of the protruding peaks above the core) (p = 0.002), Area of the Peak Region (A1, the area of the Abbott-Curve that contains the peaks from the profile) (p = 0.003) and the Skewness (Rsk, the asymmetry of the height distribution corresponding to the height or depth of surface features) (p = 0.03). We found a large variability in the measured values with a median (range) of 0.50 (0.05-2.98), 11.98 (0.46-39.98), 30.89 (0.15-581.00), and 0.04 (-0.73 0.84), respectively. A 1-unit increase in Rpk was associated with a 73% increase in the taper wear rate. The variability of "as manufactured" surface roughness has a significant effect on taper material loss.

PMID- 27704614 TI - Variation in food availability mediate the impact of density on cannibalism, growth, and survival in larval yellow spotted mountain newts (Neurergus microspilotus): Implications for captive breeding programs. AB - In this study, we examined cannibalistic behavior, growth, metamorphosis, and survival in larval and post-metamorph endangered yellow spotted mountain newts Neurergus microspilotus hatched and reared in a captive breeding facility. We designed a 2 * 2 factorial experiment, crossing two levels of food with two levels of density including high food/high density, high food/low density, low food/high density, and low food/low density. The level of cannibalistic behavior (including the loss of fore and hind limbs, missing toes, tail, gills, body damage, and whole body consumption) changed as the larvae grew, from a low level during the first 4 weeks, peaking from weeks 7 to 12, and then dropped during weeks 14-52. Both food level and density had a significant effect on cannibalism. The highest frequency of cannibalism was recorded for larvae reared in the low food/high density and lowest in high food/low density treatments. Growth, percent of larval metamorphosed, and survival were all highest in the high food/low density and lowest in low food/high density treatment. Food level had a significant effect on growth, metamorphosis, and survival. However, the two levels of density did not influence growth and metamorphosis but showed a significant effect on survival. Similarly, combined effects of food level and density showed significant effects on growth, metamorphosis, and survival over time. Information obtained from current experiment could improve productivity of captive breeding facilities to ensure the release of adequate numbers of individuals for reintroduction programs.

AB - BACKGROUND: Our study was aimed at finding out if Runx2 SNPs (single-nucleotide polymorphisms) are related to susceptibility to and prognosis of ossification of posterior longitudinal ligament (OPLL). METHODS: We selected 80 OPLL patients and another 80 independent patients without OPLL from September 2013 to November 2014. Serum was collected to detect the genotypes of rs1321075, rs12333172, and rs1406846 on Runx2 with direct sequencing analysis. RESULTS: Differences in clinical characteristics, including age, weight, height, sex ratio, as well as smoking and drinking history, between OPLL and control groups appeared to be insignificant (all P-value >.05). The allele of rs1406846 (A) emerged as a key element in raising OPLL risk with the biggest statistical significance (P<.001). Conversely, alleles of rs967588 (T) and rs16873379 (C) were associated with reduced predisposition to OPLL less remarkably (both P=.033). Regarding rs16873379, the case group exhibited a smaller frequency of homozygote CC in comparison with TT genotype than the control group (P=.016). Furthermore, the improvement rate based on calculation of JOA score suggested that genotype AA of rs6908650 was beneficial for OPLL patients' recovery from posterior laminoplasty surgery (P<.05), while genotypes of rs16873379 (CC), rs1406846 (AA), and rs2677108 (CC) significantly restrained this process (P<.05). Besides, rs16873379, rs1406846, and rs2677108 were significantly associated with number of ossification segments (P<.05). CONCLUSIONS: Runx2 SNPs (e.g., rs16873379, rs1406846, and rs2677108) were strongly correlated with onset and treatment efficacy of OPLL, and they might regulate severity of OPLL. PMID- 27704616 TI - Anatomical and functional correlates of persistent pain in Parkinson's disease. AB - BACKGROUND: The pathophysiology of pain in Parkinson's disease (PD) is still poorly understood, although it is conceivable that supraspinal mechanisms may be responsible for pain generation and maintenance. METHODS: We examined brain functional and anatomical changes associated with persistent pain in 40 PD patients, 20 with persistent pain and 20 without pain. We also examined 15 pain free healthy participants of similar age, gender, and cognitive state as a control group. We assessed pain by the King's Parkinson's Pain Scale, the Visual Analogue Scale for pain, and the Leeds Assessment for Neuropathic Symptoms and Sign. All patients underwent structural, diffusion tensor imaging, and resting state functional MRI. We compared clinical characteristics, whole-brain cortical thickness, subcortical volumes, diffusion tensor imaging scalar measures, and functional connectivity by network based statistics. RESULTS: The group with PD and persistent pain showed significant thinning in the bilateral temporal pole, left-medial orbitofrontal cortex, bilateral superior and left-inferior parietal areas, pars orbicularis, and right superior frontal, posterior cingulated, and precentral cortex. There were no significant subcortical volume and white matter differences between PD subgroups. Functional MRI showed a decrease of brain activity in the left frontal inferior orbital in PD patients with persistent pain, with greater activity bilaterally in the cerebellum and in the right inferior temporal areas. Only PD patients with persistent pain showed an accumbens-hippocampus disconnection without white matter and subcortical alterations. CONCLUSIONS: We showed that persistent pain in PD is associated with supraspinal structural and functional changes. We also highlighted the contribution of frontal, prefrontal, and insular areas in nociceptive modulation and accumbens-hippocampus disconnection.

PMID- 27704617 TI - Netazepide, a gastrin/cholecystokinin-2 receptor antagonist, can eradicate gastric neuroendocrine tumours in patients with autoimmune chronic atrophic gastritis. AB - AIMS: Netazepide, a gastrin/cholecystokinin 2 receptor antagonist, once daily for 12 weeks reduced the number of tumours and size of the largest one in 16 patients with autoimmune chronic atrophic gastritis (CAG), achlorhydria, hypergastrinaemia and multiple gastric neuroendocrine tumours (type 1 gastric NETs), and normalized circulating chromogranin A (CgA) produced by enterochromaffin-like cells, the source of the tumours. The aim was to assess whether longer-term netazepide treatment can eradicate type 1 gastric NETs. METHODS: After a mean 14 months off netazepide, 13 of the 16 patients took it for another 52 weeks. Assessments were: gastroscopy; gene-transcript expression in corpus biopsies using quantitative polymerase chain reaction; blood CgA and gastrin concentrations; and safety assessments. RESULTS: While off-treatment, the number of tumours, the size of the largest one, and CgA all increased again. Netazepide for 52 weeks: cleared all tumours in 5 patients; cleared all but one tumour in one patient; reduced the number of tumours and size of the largest one in the other patients; normalized CgA in all patients; and reduced mRNA abundances of CgA and histidine decarboxylase in biopsies. Gastrin did not increase further, confirming that the patients had achlorhydria. Netazepide was safe and well tolerated. CONCLUSIONS: A gastrin/cholecystokinin 2 receptor antagonist is a potential medical and targeted treatment for type 1 gastric NETs, and an alternative to regular gastroscopy or surgery. Treatment should be continuous because the tumours will regrow if it is stopped. Progress can be monitored by CgA in blood or biomarkers in mucosal biopsies. PMID- 27704619 TI - The contribution of policy, law, management, research, and advocacy failings to the recent extinctions of three Australian vertebrate species. AB - Extinctions typically have ecological drivers, such as habitat loss. However, extinction events are also influenced by policy and management settings that may be antithetical to biodiversity conservation, inadequate to prevent extinction, insufficiently resourced, or poorly implemented. Three endemic Australian vertebrate species-the Christmas Island pipistrelle (Pipistrellus murrayi), Bramble Cay melomys (Melomys rubicola), and Christmas Island forest skink (Emoia nativitatis)-became extinct from 2009 to 2014. All 3 extinctions were predictable and probably preventable. We sought to identify the policy, management, research, and other shortcomings that contributed to their extinctions or failed to prevent them. These included a lack within national environmental legislation and policy of explicit commitment to the prevention of avoidable extinctions, lack of explicit accountability, inadequate resources for conservation (particularly for species not considered charismatic or not of high taxonomic distinctiveness), inadequate biosecurity, a slow and inadequate process for listing species as threatened, recovery planning that failed to consider the need for emergency response, inability of researchers to identify major threatening factors, lack of public engagement and involvement in conservation decisions, and limited advocacy. From these 3 cases, we recommend: environmental policy explicitly seeks to prevent extinction of any species and provides a clear chain of accountability and an explicit requirement for public inquiry following any extinction; implementation of a timely and comprehensive process for listing species as threatened and for recovery planning; reservation alone not be assumed sufficient to maintain species; enhancement of biosecurity measures; allocation of sufficient resources to undertake actions necessary to prevent extinction; monitoring be considered a pivotal component of the conservation response; research provides timely identification of factors responsible for decline and of the risk of extinction; effective dissemination of research results; advocacy by an informed public for the recovery of threatened species; and public involvement in governance of the recovery process. These recommendations should be applicable broadly to reduce the likelihood and incidence of extinctions. PMID- 27704620 TI - The impact of vascular endothelial growth factor +405 C/G polymorphism on long term outcome and severity of coronary artery disease. AB - BACKGROUND: The association between genetic variations of vascular endothelial growth factor (VEGF) gene and the risk for atherosclerosis has been hypothesized. We aimed to assess the relationship between rs2010963 (+405 C/G) polymorphism and presence, severity, and outcome of coronary artery disease (CAD) in an Iranian cohort. METHODS: Genotyping of VEGF rs2010963 polymorphism was performed on 520 individuals, comprising 347 patients with documented coronary artery disease based on angiography report and 173 individuals with normal coronary arteries, using the TaqMan real-time PCR method. In final, 484 subjects were followed up over a 5-year period for cardiovascular-related outcomes. RESULTS: C allele of VEGF rs2010963 polymorphism was related to increase risk for CAD and also slightly to 5-year cardiovascular mortality. The 5-year survival in C and G allele subgroups were 92.3% and 94.3% in CAD group and 95.7% and 98.0% in non-CAD group, respectively. CONCLUSIONS: Vascular endothelial growth factor rs2010963 polymorphism may be associated with the presence of CAD and its long-term survival, but not with its severity. To the best of our knowledge, this is the first report of genetic association between rs2010963 SNP and CAD-related death. It can be thus suggested that rs2010963 VEGF gene can be considered as a genetic risk predictor for CAD and its outcomes. PMID- 27704621 TI - High School CPR/AED Training in Washington State. AB - OBJECTIVE: Describe the rates of CPR/AED training in high schools in the state of Washington after passage of legislation mandating CPR/AED training. DESIGN AND SAMPLE: A web-based survey was sent to administrators at 660 public and private high schools in the state of Washington. RESULTS AND CONCLUSIONS: The survey was completed by 148 schools (22%); 64% reported providing CPR training and 54% provided AED training. Reported barriers to implementation included instructor availability, cost, and a lack of equipment. Descriptive statistics were used to describe the sample characteristics and implementation rates. Mandates without resources and support do not ensure implementation of CPR/AED training in high schools. Full public health benefits of a CPR mandate will not be realized until barriers to implementation are identified and eliminated through use of available, accessible public health resources. PMID- 27704622 TI - The human gastrointestinal tract and oral microbiota in inflammatory bowel disease: a state of the science review. AB - Inflammatory bowel disease (IBD) includes a spectrum of diseases from ulcerative colitis (UC) to Crohn's disease (CD). Many studies have addressed the changes in the microbiota of individuals affected by UC and CD. A decrease in biodiversity and depletion of the phyla Bacteroidetes and Firmicutes has been reported, among others. Changes in microbial composition also result in changes in the metabolites generated in the gut from microbial activity that may involve the amount of butyrate and other metabolites such as H2 S being produced. Other factors such as diet, age, or medication need to be taken into consideration when studying dysbiosis associated with IBD. Diverse bacterial species have been associated specifically or non-specifically to IBD, but none of them have been demonstrated to be its ethiological agent. Recent studies also suggest that micro eukaryotic populations may also be altered in IBD patients. Last, but not least, viruses, and specially bacteriophages, can play a role in controlling microbial populations in the gastrointestinal tract. This may affect both bacterial diversity and metabolism, but possible implications for IBD still remain to be solved. Dysbiosis in the oral microbiome associated with IBD remains an emerging field for future research.

AB - Besides conventional flaps, intercostal artery perforator flaps have been reported to cover trunk defects. In this report the use of anterior intercostal artery perforator (AICAP) flap, lateral intercostal artery perforator (LICAP) flap and dorsal intercostal artery perforator (DICAP) flap for thoracic, abdominal, cervical, lumbar and sacral defects with larger dimensions and extended indications beyond the reported literature were reevaluated. Thirty-nine patients underwent surgery between August 2012 and August 2014. The age of the patients ranged between 16 and 79 with a mean of 49 years. The distribution of defects were as follows; 12 thoracic, 8 parascapular, 3 cervical, 8 abdominal, 4 sacral and 4 lumbar. AICAP, LICAP and DICAP flaps were used for reconstruction. Fifty-two ICAP flaps were performed on 39 patients. Flap dimensions ranged between 6 * 9 cm and 14 * 35 cm. Twenty-six patients had single flap coverage and 13 patients had double flap coverage. Forty-six flaps have been transferred as propeller flaps and 6 flaps have been transferred as perforator plus flap. Forty flaps (75%) went through transient venous congestion. In one DICAP flap, 30% of flap was lost. No infection, hematoma or seroma were observed in any patient. Follow-up period ranged between 3 and 32 months with a mean of 9 months. The ICAP flaps provide reliable and versatile options in reconstructive surgery and can be used for challenging defects in trunk. PMID- 27704626 TI - The Me3 NB12 Cl11. Radical: A Strong One-Electron Oxidizing Agent. AB - Strong oxidizing agents often contain fluorine and are not compatible with substrates forming strong element-fluorine bonds. Therefore, there is need for new strong oxidizers. Cyclic voltammetric measurements on the weakly coordinating anion [Me3 NB12 Cl11 ]- in liquid SO2 revealed an oxidation wave at +2.59 V versus Fc0/+ . The oxidation of Na[Me3 NB12 Cl11 ] with AsF5 in liquid sulfur dioxide gives the boron-cluster-based radical Me3 NB12 Cl11. as a dark blue solid in quantitative yield. The radical was characterized by vibrational, NMR, and EPR spectroscopy and by its crystal structure. To explore the potential of the radical Me3 NB12 Cl11. to act as a strong oxidizing agent, it was reacted with different compounds having high ionization energies. Thianthrene (ionization energy 7.8 eV) and hexabromobenzene (8.8 eV) were oxidized to the corresponding cations. The reaction with elemental iodine (9.3 eV) gave the [I5 ]+ cation. These reactive cations are stabilized in the solid state by the weakly coordinating anion [Me3 NB12 Cl11 ]- , which was formed as a reduced product in the oxidation reactions. PMID- 27704627 TI - Up-regulation of microRNA-491-5p suppresses cell proliferation and promotes apoptosis by targeting FOXP4 in human osteosarcoma. AB - BACKGROUND AND OBJECTIVES: MicroRNAs are small non-coding RNAs involved in pathogenesis and progression of human malignancies. MicroRNA-491-5p (miR-491-5p) is down-regulated in many human cancers where it would serve as a tumour suppressor. However, the role played by miR-491-5p in pathogenesis of human osteosarcoma has remained largely unknown. This study has been conducted to examine effects of miR-491-5p on migration and proliferation of cells of the SAOS 2 and MG63 osteosarcoma lines, and mechanisms of those effects. MATERIALS AND METHODS: Levels of miR-491-5p expression in osteosarcoma tissues and in human osteosarcoma cell lines were studied using qualitative real-time polymerase chain reaction (qRT-PCR) methods. Cell viability was detected using the CCK-8 and EdU assays, while the transwell assay was used to evaluate migration and invasion. Apoptosis was analysed uing flow cytometry and the Hoechst 33342 nuclear staining method. A dual-luciferase reporter system was used to confirm the target gene of miR-491-5p. The electrophoretic mobility shift assay (EMSA) with DIG-labelled double-stranded FOXP4 oligonucleotides was used to confirm whether or not miR-491 5p suppressed FOXP4 activation. RESULTS: Cells of osteosarcoma tissues and cell lines had low levels of miR-491-5p expression, but high levels of forkhead-box P4 (FOXP4) expression. Transfection of SAOS-2 and MG63 cells with miR-491-5p mimics inhibited expression of FOXP4 protein, which suppressed cell growth and migration, but induced apoptosis. Dual-luciferase reporter assays confirmed FOXP4 as the target gene for miR-491-5p. Overexpression of miR-491-5p suppressed FOXP4 activity in SAOS-2 and MG63 cells. Knockdown of FOXP4 in SAOS-2 and MG63 cells using an RNAi strategy resulted in reduced levels of cell proliferation and migration, but increased levels of apoptosis. CONCLUSION: Our in vitro studies showed that up-regulation of miR-491-5p suppressed proliferation of the human osteosarcoma cells and induced apoptosis by targeting FOXP4. These findings suggest that miR-491-5p could be further studied as a potential clinical diagnostic or predictive biomarker for human osteosarcoma. PMID- 27704628 TI - Effects of 12-week resistance training during radiotherapy in breast cancer patients. AB - Exercise is considered to be an effective supportive treatment approach in breast cancer (BC) patients. We conducted a randomized controlled trial to assess the efficacy of a 12-week PRT during radiotherapy. Strength performance was assessed by maximal isokinetic peak torque (MIPT) in two different angular velocities (60 degrees /s and 180 degrees /s) and maximal voluntary isometric contraction for shoulder external and internal rotation, as well as for knee extension and flexion were assessed pre- and post-intervention in 146 patients randomized to PRT or a control group. Statistical analyses were based on analysis of covariance models for the individual changes from baseline to week 13. Intention-to-treat analyses showed significant between-group differences favoring the exercise group (EX) for MIPT in knee flexion and shoulder internal and external rotation (P < 0.05). Subgroup analyses showed borderline significant differences with regard to pretreatment history, revealing that pretreated chemotherapy patients tend to benefit more from PRT than patients without chemotherapy (P = 0.06). Strength gain at the operated arm was significantly higher than at the non-operated arm in EX. PRT was efficacious in increasing upper and lower limb strength in BC patients undergoing adjuvant radiotherapy. Patients with restrictions due to breast cancer-related surgery and pretreated with chemotherapy might benefit the most. PMID- 27704629 TI - Fusobacterium necrophorum findings in Denmark from 2010 to 2014 using data from the Danish microbiology database. AB - Fusobacterium necrophorum findings in Denmark and estimation of the incidence of F. necrophorum bacteraemia was described using data from the nationwide Danish microbiology database (MiBa). All microbiological reports on any Fusobacterium species in Denmark were extracted for a period of 5 years from 2010 to 2014 from MiBa and from the local department of clinical microbiology. The overall incidence of F. necrophorum bacteraemia from 2010 to 2014 was 2.8 cases per million/year vs 9.4 in the age group 15-24 years. F. necrophorum was rare in blood cultures from children and middle-aged patients and then raised again. However, 48 of 232 cases of Fusobacterium bacteraemia were not identified to species level, so the incidences of F. necrophorum bacteraemia may be underestimated in our study. F. necrophorum was found in throat swabs in the age group between 13 and 40 years and in otitis media in children below 2 years in those departments which performed anaerobic culture. The incidence of F. necrophorum bacteraemia found was comparable to earlier reported figures for Lemierre's syndrome. Fusobacterium bacteraemia should always be identified to species level. PMID- 27704632 TI - Current and emerging therapies in premature ejaculation: Where we are coming from, where we are going. AB - Premature ejaculation is the most common form of sexual dysfunction among men. The pathophysiology of premature ejaculation appears to be multifactorial, implicating the need for multimodal therapeutic regimens to successfully treat premature ejaculation. Multiple treatment regimens have been shown to be effective in extending the time between penetration and ejaculation. These treatment modalities include everything from behavioral modifications and medications to diet alterations and major surgery. The goal of the present article was to review the commonly used treatment regimens used in the treatment of premature ejaculation, as well as to introduce and discuss the newest treatment routines under study for the treatment of premature ejaculation. PMID- 27704630 TI - Genetic architecture of motives for leisure-time physical activity: a twin study. AB - The aim of this study was to estimate the contribution of genetic and environmental influences on motives for engaging in leisure-time physical activity. The participants were obtained from the FinnTwin16 study. A modified version of the Recreational Exercise Motivation Measure was used to assess the motives for leisure-time physical activity in 2542 twin individuals (mean age of 34.1 years). Linear structural equation modeling was used to investigate the genetic and environmental influences on motive dimensions. The highest heritability estimates were found for the motive dimensions of "enjoyment" [men 33% (95% CI 23-43%), women 53% (95% CI 45-60%)] and "affiliation" [men 39% (95% CI 0.28-0.49%), women 35% (95% CI 0.25-0.43%)]. The lowest heritability estimates were found for others' expectations [men 13% (95% CI 0.04-0.25%), women 15% (95% CI 0.07-0.24%)]. Unique environmental influences explained the remaining variances, which ranged from 47% to 87%. The heritability estimates for summary variables of intrinsic and extrinsic motives were 36% and 32% for men and 40% and 24% for women, respectively. In conclusion, genetic factors contribute to motives for leisure-time physical activity. However, the genetic effects are, at most, moderate, implying the greater relative role of environmental factors. PMID- 27704631 TI - Oral spray wintertime vitamin D3 supplementation has no impact on inflammation in Gaelic footballers. AB - Vitamin D inadequacy [total 25(OH)D <50 nmol/L] is widespread in athletes. The biologically active metabolite, 1,25-dihydroxyvitamin D, may be involved in regulating inflammation although in vitro findings have not been consistently replicated in human intervention trials. This study, conducted at a latitude of 55 degrees N, aimed to assess inflammatory biomarkers in Gaelic footballers before and after a wintertime vitamin D3 intervention. Samples from a 12-week double-blind, randomized, placebo-controlled trial, in which 42 Gaelic footballers received 3000 IU (75 MUg) vitamin D3 daily or placebo via oral spray solutions, were analysed for a range of inflammatory biomarkers. Cytokines (interleukin-8 and tumor necrosis factor-alpha), cathelicidin and high sensitivity C-reactive protein were quantified by multiplex assay, enzyme-linked immunosorbent assay and clinical biochemistry, respectively. White blood cell, lymphocyte, and neutrophil concentrations were determined by full blood profile. Data on total 25-hydroxyvitamin D, measured by LC-MS/MS, were available from the previous study. Vitamin D3 supplementation significantly increased mean total 25 hydroxyvitamin D concentrations from 47 to 84 nmol/L (P = 0.006); yet this had no effect on white blood cell count (P = 0.699), lymphocyte (P = 0.694), neutrophil (P = 0.594), interleukin-8 (P = 0.334), tumor necrosis factor-alpha (P = 0.587), cathelicidin (P = 0.745) or high sensitivity C-reactive protein concentration (P = 0.621) compared to placebo. 12-weeks vitamin D3 supplementation did not impact the immune profile of Gaelic footballers. This is likely because biomarkers were within their respective normal range or at a concentration similar to that of the general population at baseline. Future studies are encouraged to use inflammation as their primary outcome measure and recruit athletes at risk of compromised immunity. PMID- 27704633 TI - Plants as Antileishmanial Agents: Current Scenario. AB - Leishmaniasis is a clinical manifestation caused by the parasites of the genus Leishmania. Plants are reservoirs of bioactive compounds, which are known to be chemically balanced, effective and least injurious as compared with synthetic medicines. The current resistance and the toxic effects of the available drugs have brought the trend to assess the antileishmanial effect of various plant extracts and their purified compound/s, which are summarized in this review. Moreover, it also highlights various traditional remedies used by local healers against leishmaniasis. A systematic cross-sectional study for antileishmanial activity of natural products was carried out using multiple literature databases. The records retrieved since 2000 till year 2016 were analysed and summarized in the form of comprehensive tables and graphs. Natural products are potential source of new and selective agents that can significantly contribute to primary healthcare and probably are promising substitutes of chemicals for the treatment of protozoan diseases like leishmaniasis. Where the researchers prefer to use alcoholic solvents for the extraction of antileishmanial agents from plants, most of the studies are limited to in vitro conditions majorly on using promastigote forms of Leishmania. Thus, there is a need to carry out such activities in vivo and in host macrophages. Further, there is a need of mechanistic studies that can help taking few of the promising pure compounds to clinical level. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27704634 TI - Advancement of the Subjective Vitality Scale: examination of alternative measurement models for Japanese and Singaporeans. AB - The Subjective Vitality Scale (SVS: Ryan & Frederick, 1997) is a 7-item self report instrument to measure one's level of vitality and has been widely used in psychological studies. However, there have been discrepancies in which version of the SVS (7- or 6-item version) employed between as well as within researchers. Moreover, Item 5 seems not be a good indicator of vitality from a content validity perspective. Therefore, the present study aimed to evaluate the validity and reliability of the SVS for Japanese and Singaporeans rigorously by comparing 3 measurement models (5-, 6-, and 7-item models). To this end, the scale was first translated from English to Japanese and then the Japanese and English versions of the scale were administered to Japanese (n = 268) and Singaporean undergraduate students (n = 289), respectively. The factorial and concurrent validity of the three models were examined independently on each of the samples. Furthermore, the covariance stability of the vitality responses was assessed over a 4-week time period for another independent Japanese sample (n = 140). The findings from this study indicated that from methodological and content validity perspectives, the 5-item model is considered most preferable for both language versions of the SVS.

AB - BACKGROUND: Oral cancer is the sixth most common malignancy in the world. Viruses are the causative agents of approximately 10-15% of all cancers worldwide (Cancers, 6, 2014 and 2155). The tumorigenic roles of Epstein-Barr virus in oral cancer are unclear. Literature search results are conflicting and dependent on various factors such as geographical/regional variations, sociocultural lifestyles, dietary habits, chewing/smoking tobacco habit. This study is the first original observation about frequency of Epstein-Barr virus among South Indian tobacco-chewing patients to elucidate its involvement in oral carcinogenesis and to know whether this can be a valuable diagnostic and prognostic indicator. MATERIALS AND METHODS: A total number of 75 tobacco chewer subjects aged between 23 and 76 years with histopathologically confirmed oral potentially malignant disorders (25), oral squamous cell carcinoma (25), and age matched healthy controls (25) formed the study group. Immunohistochemical expression of Epstein-Barr virus latent membrane protein 1 was assessed among cases and healthy controls. RESULTS: Out of the total 75 subjects, six subjects (8%) were positive for Epstein-Barr virus antigen and 69 subjects (92%) negative. The antigen positivity was observed among two cases of moderately differentiated oral squamous cell carcinoma, two cases of leukoplakia, and two healthy controls. CONCLUSION: No significant association between Epstein-Barr virus positivity was observed among oral potentially malignant disorders and oral squamous cell carcinoma among South Indian tobacco-chewing patients. This can be partially explained by the methodology employed, by the patient population analyzed and different habits in various geographical regions. PMID- 27704637 TI - Retrospective analysis of in vivo recovery and clearance during continuous infusion of recombinant factor VIII products: a single-institution study. AB - BACKGROUND: Continuous infusion (CI) of recombinant FVIII (rFVIII) concentrates has been reported as an effective and safe method to achieve haemostasis during major surgeries or severe bleeding events. For more effective and safer CI, better understanding of in vivo recovery (IVR) and clearance (CL) issues is imperative. OBJECTIVE: We investigated the following factors affecting IVR and CL using univariate and multivariate regression analyses during 47 CIs in 34 patients: rFVIII concentrate type, haemophilia severity, blood type, the presence of hepatitis C virus (HCV) or human immunodeficiency virus (HIV), age and body mass index (BMI). RESULTS: The mean IVR was 1.64 +/- 0.49 IU dL-1 per IU kg-1 , and the mean CL during CI was 3.56 +/- 1.57 mL h-1 kg-1 . The univariate and multivariate regression analyses showed that the CL of octocog alfa was significantly lower than that of rurioctocog alfa (P = 0.043 and 0.0034, respectively). There was a significant difference in BMI in the univariate and multivariate regression analyses (P = 0.0403 and 0.0376, respectively). CONCLUSIONS: This study indicated that CL during CI was potentially affected by the type of rFVIII concentrate used and BMI. PMID- 27704638 TI - Control of Bone Anabolism in Response to Mechanical Loading and PTH by Distinct Mechanisms Downstream of the PTH Receptor. AB - Osteocytes integrate the responses of bone to mechanical and hormonal stimuli by poorly understood mechanisms. We report here that mice with conditional deletion of the parathyroid hormone (PTH) receptor 1 (Pth1r) in dentin matrix protein 1 (DMP1)-8kb-expressing cells (cKO) exhibit a modest decrease in bone resorption leading to a mild increase in cancellous bone without changes in cortical bone. However, bone resorption in response to endogenous chronic elevation of PTH in growing or adult cKO mice induced by a low calcium diet remained intact, because the increased bone remodeling and bone loss was indistinguishable from that exhibited by control littermates. In contrast, the bone gain and increased bone formation in cancellous and cortical bone induced by daily injections of PTH and the periosteal bone apposition induced by axial ulna loading were markedly reduced in cKO mice compared to controls. Remarkably, however, wild-type (WT) control littermates and transgenic mice overexpressing SOST injected daily with PTH exhibit similar activation of Wnt/beta-catenin signaling, increased bone formation, and cancellous and cortical bone gain. Taken together, these findings demonstrate that Pth1r in DMP1-8kb-expressing cells is required to maintain basal levels of bone resorption but is dispensable for the catabolic action of chronic PTH elevation; and it is essential for the anabolic actions of daily PTH injections and mechanical loading. However, downregulation of Sost/sclerostin, previously shown to be required for bone anabolism induced by mechanical loading, is not required for PTH-induced bone gain, showing that other mechanisms downstream of the Pth1r in DMP1-8kb-expressing cells are responsible for the hormonal effect.

AB - Length of hospital stay (LOS) is an important indicator of the hospital activity and management of health care. The skewness in the distribution of LOS poses problems in statistical modelling because it fails to adequately follow the usual traditional distribution of positive variables such as the log-normal distribution. We present in this paper a model using the convolution of two distributions, a technique well known in the signal processing community. The specificity of that model is that the variable of interest is considered to be the resulting sum of two random variables with different distributions. One of the variables features the patient-related factors in terms of their need to recover from their admission condition, while the other models the hospital management process such as the discharging process. Two estimation procedures are proposed. One is the classical maximum likelihood, while the other relates to the expectation-maximization algorithm. We present some results obtained by applying this model to a set of real data from a group of hospitals in Victoria (Australia). Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27704640 TI - Vertical augmentation of the posterior atrophic mandible by interpositional grafts in a split-mouth design: a human tomography evaluation pilot study. AB - OBJECTIVE: Using computed tomography, to compare vertical and volumetric bone augmentation after interposition grafting with bovine bone mineral matrix (GEISTLICH BIO-OSS(r) ) or hydroxyapatite/tricalcium phosphate (STRAUMANN(r) BONECERAMIC) for atrophic posterior mandible reconstruction through segmental osteotomy. MATERIAL AND METHODS: Seven patients received interposition grafts in the posterior mandible for implant rehabilitation. The computed tomography cone beam images were analysed with OsiriX Imaging Software 6.5 (Pixmeo Geneva, Switzerland) in the pre-surgical period (T0), at 15 days post-surgery (T1) and at 180 days post-surgery (T2). The tomographic analysis was performed by a single trained and calibrated radiologist. Descriptive statistics and nonparametric methods were used to analyse the data. RESULTS: There was a significant difference in vertical and volume augmentation with both biomaterials using the technique (P < 0.05). There were no significant differences (P > 0.05) in volume change of the graft, bone volume augmentation, or augmentation of the maximum linear vertical distance between the two analysed biomaterials. CONCLUSIONS: The GEISTLICH BIO-OSS(r) and STRAUMANN(r) BONECERAMIC interposition grafts exhibited similar and sufficient dimensional stability and volume gain for short implants in the atrophic posterior mandible.

A new pyridine additive with a long alkyl chain substituted at its o-position does not corrode perovskite. The stability of devices containing this additive is the highest among the investigated cells. PMID- 27704641 TI - Parametrial involvement in women with low-risk, early-stage cervical cancer. AB - This study identified the incidence of parametrial involvement in low risk, early stage cervical cancer patients and evaluated the factors associated with parametrial involvement. All stage IA2-IB1 cervical cancer patients who underwent radical hysterectomy with pelvic lymphadenectomy were retrospectively reviewed. Patients with squamous cell carcinoma or adenocarcinoma grade 1-2, tumour size less than 2 cm, no lymphovascular space invasion (LVSI), negative pelvic nodes and depth of stromal invasion (DSI) less than 10 mm were identified as the low risk group. A total of 243 patients were eligible. Squamous cell carcinomas were the most frequent histological cell type (65%). Most patients (81.5%) had tumour size less than 2 cm. Thirteen patients (5.3%) had parametrial involvement, 77 (31.7%) had DSI more than 10 mm, 121 (49.8%) had more than 50% invasion, 119 (49%) had LVSI and 19 (7.5%) had node metastasis. Ninety-five patients (39.1%) were defined as low risk. None of low-risk group had parametrial involvement. DSI more than 10 mm or more than 50% stromal invasion, presence of LVSI and pelvic node metastasis were significant factors associated with parametrial involvement. Parametrial involvement in low-risk, early-stage cervical cancer is extremely low. Less radical surgery may be an alternative treatment option.

AB - RATIONALE: For unambiguous identification of Chemical Weapons Convention (CWC) related chemicals in environmental samples, the availability of mass spectra, interpretation skills and rapid microsynthesis of suspected chemicals are essential requirements. For the first time, the electron ionization single quadrupole and electrospray ionization tandem mass spectra of a series of O-alkyl N-[bis(dimethylamino)methylidene]-P-methylphosphonamidates (Scheme 1, cpd 4) were studied for CWC verification purposes. METHODS: O-Alkyl N [bis(dimethylamino)methylidene]-P-methylphosphonamidates were prepared through a microsynthetic method and were analyzed using electron ionization and electrospray ionization mass spectrometry with gas and liquid chromatography, respectively, as MS-inlet systems. General EI and ESI fragmentation pathways were proposed and discussed, and collision-induced dissociation studies of the protonated derivatives of these compounds were performed to confirm proposed fragment ion structures by analyzing mass spectra of deuterated analogs. RESULTS: Mass spectrometric studies revealed some interesting fragmentation pathways during the ionization process, such as McLafferty rearrangement, hydrogen rearrangement and a previously unknown intramolecular electrophilic aromatic substitution reaction. CONCLUSIONS: The EI and ESI fragmentation routes of the synthesized compounds 4 were investigated with the aim of detecting and identifying CWC-related chemicals during on-site inspection and/or off-site analysis and toxic chemical destruction monitoring.

AB - The aim of this cross-sectional study was to compare mobility and muscle strength in male former elite endurance and power athletes aged 66-91 years (n = 150; 50 men in both former elite athlete groups and in their control group). Agility, dynamic balance, walking speed, chair stand, self-rated balance confidence (ABC scale), jumping height, and handgrip strength were assessed. Former elite power athletes had better agility performance time than the controls (age- and body mass index, BMI-adjusted mean difference -3.6 s; 95% CI -6.3, -0.8). Adjustment for current leisure time physical activity (LTPA) and prevalence of diseases made this difference non-significant (P = 0.214). The subjects in the power sports group jumped higher than the men in the control group (age- and BMI-adjusted mean differences for vertical squat jump, VSJ 4.4 cm; 95% CI 2.0, 6.8; for countermovement jump, CMJ 4.0 cm; 95% CI 1.7, 6.4). Taking current LTPA and chronic diseases for adjusting process did not improve explorative power of the model. No significant differences between the groups were found in the performances evaluating dynamic balance, walking speed, chair stand, ABC-scale, or handgrip strength. In conclusion, power athletes among the aged former elite sportsmen had greater explosive force production in their lower extremities than the men in the control group. PMID- 27704645 TI - Investigation of the anticoagulant and antithrombotic effects of chlorogenic acid. AB - Thrombosis is a leading cause of morbidity and mortality throughout the world. Thrombolytic agents are important for both the prevention and treatment of thrombosis. Fibrin clot and turbidity assays revealed that it was able to inhibit the formation of fibrin clot. Chlorogenic acid degraded blood clot and inhibited the enzymatic activity of procoagulant proteases, thrombin, activated factor X (FXa), and activated factor XIII (FXIIIa). Chlorogenic acid was found to delay activated partial thromboplastin time, prothrombin time, and thrombin time. PFA 100 assays showed that it prolonged the closure time of citrated whole human blood. It demonstrated the antithrombotic effect in collagen and epinephrine induced acute thromboembolism mice model. These antithrombotic profiles together with its anticoagulant and platelet disaggregation properties, and lack of toxicity to NIH-3T3 and 3T3-L1 cells, make it a potential agent for thrombotic treatment and prevention.

AB - Colorectal cancer (CRC) screening participation remains unacceptably low. This study investigated the emotion of disgust as a potential deterrent to intention to screen for CRC. The study utilised a convenience sample of individuals' 40-70 years of age to complete an online survey. Participants included 30 men and 118 women recruited between December 1, 2013 and March 31, 2014. Data on socio demographics, health status, screening intentions and emotional barriers to bowel screening were collected via an on-line survey. Logistic regression analysis was utilised to investigate predictors of screening intention. Individuals were more likely to report intention to screen if they had prior screening experience, and reported fewer emotional concerns to screening for CRC. Results implicate disgust as a predictor of screening avoidance among participants. Specifically, higher reported faecal disgust was predictive of a 3% decrease in screening intention. This study was the first to empirically position disgust alongside other negative emotional states as an affective barrier to screening for CRC. Trait disgust sensitivity was not a reliable predictor of screening intention. This research suggests that anticipated faecal disgust may contribute to avoidance of screening for CRC.

PMID- 27704649 TI - Predicting lymph node metastasis in patients with papillary thyroid carcinoma by vascular index on power Doppler ultrasound. AB - BACKGROUND: For patients with papillary thyroid carcinoma (PTC), lymph node metastasis is associated with an increased recurrence rate. The purpose of this study was to investigate whether the vascular endothelial growth factor (VEGF), microvessel density (MVD), and vascular index (VI) can predict lymph node metastasis in patients with PTC. METHODS: From January 2011 to October 2011, 202 patients with PTCs underwent preoperative staging ultrasound evaluation. To evaluate vascularity, we measured the VI, VEGF expression, and MVD. RESULTS: The VI was significantly correlated with MVD (p = .009). On multivariate analysis, young age showed a significant correlation with lymph node metastasis (p < .001; p < .001; p < .001). However, the other clinicopathologic features, VEGF, MVD, and VI failed to show any significant correlations with lymph node metastasis. CONCLUSION: Although the VI showed significant correlation with MVD, it was not significantly correlated to lymph node metastasis. (c) 2016 Wiley Periodicals, Inc. Head Neck 39: 334-340, 2017. PMID- 27704650 TI - Core-needle biopsy versus repeat fine-needle aspiration for thyroid nodules initially read as atypia/follicular lesion of undetermined significance. AB - BACKGROUND: The purpose of this study was to evaluate the role of core-needle biopsy (CNB) by comparing the results of CNB and repeat fine-needle aspiration (FNA) for thyroid nodules that are initially read as atypia/follicular lesion of undetermined significance (AUS/FLUS) on FNA. METHODS: Among 2631 initial AUS/FLUS FNA results, 505 consecutive nodules (295 repeat FNAs and 210 CNBs) were retrospectively analyzed. The primary outcome was inconclusive (ie, nondiagnostic or AUS/FLUS). The secondary outcomes included inconclusive results of the subcategory, risk factors for inconclusive results, and diagnostic performance. RESULTS: CNB demonstrated significantly fewer inconclusive results than repeat FNA for the overall nodules (40.9% vs 63%; p < .001). Repeat FNA and group FLUS were significant risk factors for inconclusive results (odds ratio = 1.92; p =.001 and odds ratio = 2.08; p <.001, respectively). All diagnostic performances using CNB were higher than repeat FNAs. CONCLUSION: CNB is more useful than repeat FNAs for reducing inconclusive results and improving the diagnostic performance of thyroid nodules with initial AUS/FLUS FNA results.

PMID- 27704652 TI - Epidemiology, clinical characteristics, laboratory findings and severity of respiratory syncytial virus acute lower respiratory infection in Malaysian children, 2008-2013. AB - AIM: The aim of this study is to describe epidemiology, clinical features, laboratory data and severity of respiratory syncytial virus (RSV) acute lower respiratory infection (ALRI) in Malaysian children and to determine risk factors associated with prolonged hospital stay, paediatric intensive care unit (PICU) admission and mortality. METHODS: Retrospective data on demographics, clinical presentation, outcomes and laboratory findings of 450 children admitted into Tuanku Jaafar Hospital in Seremban, Malaysia from 2008 to 2013 with documented diagnosis of RSV ALRI were collected and analysed. RESULTS: Most admissions were children below 2 years old (85.8%; 386/450). Commonest symptoms were fever (84.2%; 379/450), cough (97.8%; 440/450) and rhinorrhea (83.6%; 376/450). The median age among febrile patients (n = 379) was 9.0 months with interquartile range (IQR) of 4.0-19.0 months whereas the median age among those who were apyrexial (n = 71) was 2 months with IQR of 1-6 months (P-value <0.001). 15.3% (69/450) needed intensive care and 1.6% (7/450) died. Young age, history of prematurity, chronic comorbidity and thrombocytosis were significantly associated with prolonged hospital stay, PICU admission and mortality. CONCLUSIONS: Infants less than 6 months old with RSV ALRI tend to be afebrile at presentation. Younger age, history of prematurity, chronic comorbidity and thrombocytosis are predictors of severe RSV ALRI among Malaysian children. Case fatality rate for Malaysian children below 5 years of age with RSV ALRI in our centre is higher than what is seen in developed countries, suggesting that there is room for improvement. PMID- 27704653 TI - High-dose intravenous steroid regimen for radiation-induced hypoglossal nerve palsy. AB - BACKGROUND: Hypoglossal nerve palsies are infrequent complications of head and neck radiotherapy. Treatments focus on maintaining function and prevention of abnormal airway-related swallowing events. METHODS: A patient with longstanding cranial neuropathies, including bilateral hypoglossal involvement, secondary to chemoradiotherapy for nasopharyngeal carcinoma, experienced repeated episodes of life-threatening complications. Initially, 2 courses of 2 weekly 24-hour intravenous methylprednisolone (IVMP) infusions were administered 2 years apart. We report the results of a third course comprising 5 weekly cycles. RESULTS: Patient-reported outcomes revealed significant improvement in swallowing function, speech, and psychosocial status. Airway invasion during swallowing and pharyngeal retention were assessed videofluoroscopically and evaluated using the Penetration-Aspiration Scale (PAS) and a residue rating scale, respectively. PAS ratings after infusions 2 and 5, improved dramatically from baseline and were maintained at 1-year follow-up. CONCLUSION: High doses of IVMP may improve radiation-induced neuropathies. Further testing in similar patients is needed to prove reproducibility. (c) 2016 Wiley Periodicals, Inc. Head Neck 39: E23-E28, 2017.

AB - OBJECTIVE: To evaluate whether and to which extent skin redness (erythema) affects investigator blinding in transcranial direct current stimulation (tDCS) trials. MATERIAL AND METHODS: Twenty-six volunteers received sham and active tDCS, which was applied with saline-soaked sponges of different thicknesses. High resolution skin images, taken before and 5, 15, and 30 min after stimulation, were randomized and presented to experienced raters who evaluated erythema intensity and judged on the likelihood of stimulation condition (sham vs. active). In addition, semi-automated image processing generated probability heatmaps and surface area coverage of erythema. Adverse events were also collected. RESULTS: Erythema was present, but less intense in sham compared to active groups. Erythema intensity was inversely and directly associated to correct sham and active stimulation group allocation, respectively. Our image analyses found that erythema also occurs after sham and its distribution is homogenous below electrodes. Tingling frequency was higher using thin compared to thick sponges, whereas erythema was more intense under thick sponges. CONCLUSIONS: Optimal investigator blinding is achieved when erythema after tDCS is mild. Erythema distribution under the electrode is patchy, occurs after sham tDCS and varies according to sponge thickness. We discuss methods to address skin erythema-related tDCS unblinding. PMID- 27704656 TI - Long-term liver-related morbidity and mortality related to chronic hepatitis C virus infection in Swedish patients with inherited bleeding disorders. AB - INTRODUCTION: Hepatitis C virus (HCV) infection is common in patients with inherited bleeding disorders treated with clotting factor concentrates prior to the introduction of viral inactivation of these products. The long-term consequences of hepatitis C infection in Swedish patients are not fully understood. AIM: To examine the impact of HCV infection on liver-related morbidity and mortality in Swedish patients with inherited bleeding disorders. METHODS: We retrospectively collected data on 183 patients with inherited bleeding disorders infected with HCV who attended the Coagulation Unit at Karolinska University Hospital, Sweden. Data regarding end-stage liver disease (ESLD), defined as presence of ascites, encephalopathy, variceal bleeding, hepatocellular carcinoma or liver-related death, were collected from the patient records and the national registers. RESULTS: The median follow-up time was 35.9 years (IQR 29.0-41.2). A total of 41% had achieved sustained virological response (SVR) after treatment. In total, 14.2% developed ESLD at the median age of 52.6 years (IQR 46.5-64.7). Nineteen (35.8%) of all deaths were due to liver-related causes. Co-infection with human immunodeficiency virus (HIV), older age at time of infection and severe form of bleeding disorder was associated with higher risk of developing ESLD, while SVR was a strong protective factor. CONCLUSIONS: This study demonstrated that liver-related morbidity and mortality was significant in patients with bleeding disorders and HCV infection in Sweden. Patients with HCV infection should be candidates for treatment with the new highly effective antiviral drugs, since SVR proved to be a strong protective factor.

PMID- 27704657 TI - Spontaneous haemoperitoneum in pregnancy and endometriosis: a case series. AB - OBJECTIVE: To report pregnancy outcomes of SHiP (spontaneous haemoperitoneum in pregnancy) and the association with endometriosis. DESIGN: Retrospective case note review. SETTING: Dutch referral hospitals for endometriosis. SAMPLE: Eleven women presenting with 15 events of SHiP. METHODS: In collaboration with the Dutch Working Group on Endometriosis, unpublished cases of SHiP that occurred in the Netherlands between 2010 and 2015 were retrieved. MAIN OUTCOME MEASURES: Maternal and perinatal mortality and morbidity. RESULTS: SHiP occurred predominantly in the second and third trimester of pregnancy. The earliest and major presenting symptom was an acute onset of abdominal pain, often combined with low haemoglobin levels or signs of fetal distress. Imaging was a diagnostic tool when free peritoneal fluid could be observed. For surgical treatment of the bleeding site, a midline laparotomy was mostly needed, the median estimated amount of blood loss was 2000 mL. No fetomaternal or perinatal mortality was reported, despite a high rate of preterm births (54.5%). In all women, endometriosis was diagnosed at a certain moment in time and therefore was probably involved in the pathogenesis of SHiP. Four women showed recurrence of SHiP. In one of these cases the second event of SHiP occurred in a subsequent pregnancy. CONCLUSION: Pregnancy outcomes of SHiP are improving when compared with previous reports, with absent fetomaternal and perinatal mortality in this recent series. Growing knowledge and adequate multidisciplinary intervention may have contributed to these favourable results. Increasing awareness of this serious complication of pregnancy is advocated, especially in women diagnosed with endometriosis. TWEETABLE ABSTRACT: Growing awareness of SHiP is advocated, especially in women diagnosed with endometriosis. PMID- 27704659 TI - An assessment of the relationship between the World Health Organization HIV drug resistance early warning indicators and HIV drug resistance acquisition. AB - OBJECTIVES: The World Health Organization (WHO)'s HIV drug resistance (HIVDR) early warning indicators (EWIs) measure antiretroviral therapy (ART)-site factors associated with HIVDR prevention, without HIVDR laboratory testing. We assessed the relationship between EWIs and HIVDR acquisition using data from British Columbia, Canada. METHODS: Eligible patients were ART-naive, were >= 19 years old, had initiated ART between 1 January 2000 and 31 December 2012, had >= 15 months of follow-up, and were without transmitted HIVDR. Patients were followed for acquired HIVDR until 31 March 2014, the last contact date, or death. We built logistic regression models to assess the associations and predictive ability of individual indicators and of the EWI Score (the number of indicators for which a patient did not meet the criteria) on HIVDR acquisition (to any class of HIVDR, lamivudine (3TC)/emtricitabine (FTC), nonnucleoside reverse transcriptase inhibitors (NNRTIs), nucleoside reverse transcriptase inhibitors (NRTIs) or protease inhibitors (PIs)]). RESULTS: All explored EWIs were associated with at least one class of HIVDR, with the exception of 'ART prescribing practices'. We observed a dose-response relationship between acquiring HIVDR to any antiretroviral class and an increasing EWI score in our predictive logistic regression model. The area under the curve was 0.848 (excellent discrimination). The adjusted odds ratios for acquiring any class of HIVDR for an EWI score of 1, 2 and >= 3 versus 0 were 2.30 [95% confidence Interval (CI) 1.21-4.38], 3.35 (95% CI: 1.86-6.03) and 7.26 (95% CI: 4.18-12.61), respectively. CONCLUSIONS: Several EWIs were associated with and predictive of HIVDR, supporting the WHO EWIs as a component of the HIVDR prevention method in settings where HIVDR testing is not routinely or widely available. PMID- 27704660 TI - Efficacy of ultrasound-guided fine-needle aspiration performed by surgeons newly trained in thyroid ultrasound. AB - BACKGROUND: There are a growing number of thyroid ultrasound courses to train endocrinologists, pathologists, and surgeons to perform ultrasound-guided fine needle aspiration (FNA). However, there are limited data to support the efficacy of ultrasound-guided FNA performed by nonradiologists. METHODS: We compared the efficacy of ultrasound-guided FNA performed by surgeons newly trained in thyroid ultrasound with that of the same technique performed by 1 experienced radiologist. The ratio of nondiagnostic examinations was used to compare the 2 groups. RESULTS: A total of 197 ultrasound-guided FNAs were performed on 172 women (95.53%) and 8 men (4.47%) over a 12-month period. The efficacy of ultrasound-guided FNA did not differ between groups. A nondiagnostic report was found in 23% and 25.7% of the examinations performed by the radiologist and surgeons, respectively. CONCLUSION: The efficacy of ultrasound-guided FNAs performed by our 2 surgeons was similar to that of our radiologist. (c) 2016 Wiley Periodicals, Inc. Head Neck 39: 439-442, 2017. PMID- 27704662 TI - Cigarette smoking alters sialylation in the Fallopian tube of women, with implications for the pathogenesis of ectopic pregnancy. AB - Sialylation creates a negative charge on the cell surface that can interfere with blastocyst implantation. For example, alpha2,6-sialylation on terminal galactose, catalyzed by the sialyltransferase ST6GAL1, inhibits the binding of galectin-1, a beta-galactoside-binding lectin. We recently reported the potential involvement of galectin-1 and -3 in the pathogenesis of tubal ectopic pregnancy; however, the precise role of galectins and their ligand glycoconjugates remain unclear. Here, we investigated the expression of the genes encoding alpha2,3- and alpha2,6 galactoside sialyltransferases (ST3GAL1-6 and ST6GAL1-2) and the localization of sialic acids in the Fallopian tube of women with or without ectopic implantation. ST6GAL1 expression was higher in the mid-secretory phase than the proliferative phase of non-pregnant women (P < 0.0001), whereas ST6GAL1 (P < 0.0001), ST3GAL3 (P = 0.0029), ST3GAL5 (P = 0.0089), and ST3GAL6 (P = 0.0018) were all lower in Fallopian tubes with ectopic implantations. alpha2,3- and alpha2,6-sialic acids, however, both remained enriched on the surface of Fallopian tube epithelium. Cigarette smoking, a major risk factor for tubal ectopic pregnancy, was associated with reduced mid-secretory-phase expression of ST6GAL1 (P = 0.0298), but elevated expression of ST3GAL5 (P = 0.0006), an enzyme known to be involved in ciliogenesis. Indeed, sialic acid-containing ciliated inclusion cysts, which are associated with abnormal ciliogenesis, were observed within the epithelium at a higher frequency in women who smoked (P = 0.0177), suggesting that abnormal ciliogenesis is associated with smoking. Thus, cigarette smoking alters sialylation in the Fallopian tube epithelium, and is potentially a source of decreased tubal transport and increased receptivity for blastocyst in the human Fallopian tube.

PMID- 27704661 TI - Isolated local recurrence or solitary solid organ metastasis after esophagectomy for cancer is not the end of the road. AB - Recurrent disease after esophagectomy bears an infaust prognosis, especially when multiple recurrences are present. But little is known about survival in patients with limited recurrence (solitary locoregional recurrence or solid organ metastasis). Herein, we report our experience with these subgroups. We analyzed 1754 consecutive patients surgically treated with curative resection for esophageal cancer and cancer of the gastroesophageal junction between 1990 and 2012. Seven subgroups were defined according to the recurrence type (locoregional vs. organ metastasis), the site of recurrence (abdominal, thoracic, cervical for lymph nodes and lung, liver, adrenals and others for organ metastasis) and also the number of lesions (one vs. multiple lymph node stations or organ metastasis) Of these groups; clinical isolated locoregional recurrence (ciLR) was defined as solitary lymph-node recurrence confined to one compartment (cervical, thoracic or abdominal, within or outside surgical dissection-field) at clinical staging. Clinical solitary solid organ metastasis (csSOM) was defined as metastasis in a resectable solid organ, i.e. liver, lung, brain or adrenal. Salvage therapies were grouped in five categories. Kaplan-Meier curves were used to calculate survival. Recurrent disease was observed in 766 patients (43.7%) with overall 5 year survival of 4.5% after diagnosis of recurrence. Fifty-seven patients (7.4%) showed ciLR and 110 (14.4%) csSOM. Median time-to-recurrence was 16.8 months in ciLR and 9.9 months in csSOM (P = 0.0074). Survival is significantly improved compared to supportive therapy when local therapy is possible (P < 0.0001). In 25 (15%) of ciLR or csSOM patients, surgical therapy with or without systemic therapy, yielded a 5-year survival of 49.9% (median 54.8 months) after diagnosis of recurrence. When surgery was impossible or contraindicated, the combination of chemoradiotherapy appeared to be superior to chemotherapy alone (respectively 27.0% vs. 4.6% 5-year survival) or radiotherapy alone (no 5-year survival). Recurrent disease after esophagectomy is a common problem with poor overall survival. However prolonged survival could be obtained in selected patients if the recurrent disease is limited to ciLR or csSOM, if surgery (+/- systemic therapy) can be performed. If not a combination of chemoradiotherapy seems to offer the second best option. Patients presenting with a ciLR or csSOM should be discussed in a dedicated multidisciplinary team meeting as to evaluate and define the place of salvage treatment which in well selected cases could offer a perspective of prolonged survival. PMID- 27704663 TI - Parent-Related Stress of Male and Female Carers of Adolescents with Intellectual Disabilities and Carers of Children within the General Population: A Cross Sectional Comparison. AB - BACKGROUND: Carers of children with intellectual disability show high rates of parent-related stress and are at an increased risk for deleterious physical and mental health. MATERIALS AND METHODS: This study investigated the relationship between demographic and social characteristics and parenting stress, within two different cross-sectional samples of carers: those who care for an adolescent with an intellectual disability and carers from a population based sample. Participants were 1152 carers from the Household Income and Labour Dynamic in Australia study and 284 carers of adolescents with intellectual disabilities from the Ask study. RESULTS AND CONCLUSIONS: The results supported previous research suggesting carers of children with intellectual disabilities experience high parent-related stress. The results also support the buffer model of social support, as high social support was related to lower parent-related stress. Self rated prosperity, financial pressure and relationship status were also related to lower levels of parent-related stress. PMID- 27704664 TI - Content analysis of public opinion on sexual expression and dementia: Implications for nursing home policy development. AB - PURPOSE: We examined public opinion of sexual expression and dementia to inform nursing home policy and practice. DESIGN AND METHODS: A content analysis was conducted on public comments (N=1194) posted in response to a New York Times article about a highly publicized legal case involving a husband engaging in sexual acts with his wife who had dementia, living in a nursing home. Researchers utilized constant comparative analysis to code the comments; reliability analysis showed moderately strong agreement at the subcategory level. Data were also coded to indicate whether the commenter thought the couple should or should not have been allowed to be sexual. RESULTS: One primary theme was identified: conditions necessary for someone to be sexual. Six categories were identified within this theme, with the public commentary considering factors such as marital relationships, intimacy needs and several sexual consent-related issues as key conditions necessary to be sexual in a nursing home setting. Overall, the majority of commenters were in support of sexual expression for an individual with dementia in the described situation. DISCUSSION: This study revealed sexual expression among individuals with dementia is a contentious issue with strong public opinions about how this should be managed in a nursing home setting. These opinions should be considered as policy related to sexual expression in nursing homes is developed. PMID- 27704665 TI - Predictive parameter of tolvaptan effectiveness in cirrhotic ascites. AB - AIMS: The efficacy of the vasopressin V2 receptor antagonist tolvaptan for difficult-to-treat cirrhotic ascites has recently been reported. However, its effect is variable among patients. This study aimed to clarify the predictive factors for obtaining a good response to tolvaptan in patients with difficult-to treat ascites. METHODS: Data were collected from 50 patients with liver cirrhosis having ascites (hepatitis B, n = 1; hepatitis C, n = 22; alcoholism, n = 11; and others, n = 16) after treatment with tolvaptan (3.75-7.5 mg/day) in addition to conventional diuretics. A follow-up assessment was carried out after 7-day tolvaptan treatment for all patients. RESULTS: After an uneventful 7-day tolvaptan treatment, 18 patients (36.0%) lost more than 2 kg of their body weight (responders). Twenty-six patients (52.0%) showed an increase in urine volume (>300 mL) on day 2. Tolvaptan was also effective for patients with pleural effusion, portal vein thrombosis, and hepatocellular carcinoma. Basal blood urea nitrogen (BUN) levels, plasma renin activity, and aldosterone levels were significantly higher in the poor responders (<2 kg weight loss), who were considered to be in the relative vascular underfilling state, than in the responders. Basal BUN was extracted as a predictive factor of responsiveness by multivariate logistic regression analysis. CONCLUSIONS: Tolvaptan is useful and safe for the treatment of cirrhotic ascites. This report showed that BUN will predict the response of tolvaptan even when measured before tolvaptan treatment. PMID- 27704666 TI - Versatility of the facial artery myomucosal island flap in neopharyngeal reconstruction. AB - BACKGROUND: The facial artery myomucosal (FAMM) island flap is a cheek flap, pedicled on the facial artery and suitable for small to medium-sized reconstructions of the oral cavity and neighboring areas. A novel transposition of the flap to the hypopharynx after laryngectomy is presented in this report. METHODS: A 58-year-old man, previously irradiated, was laryngopharyngectomized because of a new supraglottic carcinoma. An unexpected need for a flap was solved by tunneling a FAMM island flap lateral to the mandible. The reach and size of the flap were sufficient to close the defect. RESULTS: Vitality of the flap was ascertained by fiber endoscopy. No donor-site morbidity was seen. Postoperatively, the patient had a minor stomal fistula with spontaneous healing. CONCLUSION: The pedicled FAMM island flap may be considered for smaller reconstructions of the upper hypopharynx. Accessibility, low donor-site morbidity, and recipient tissue similarity count among the advantages. (c) 2016 Wiley Periodicals, Inc. Head Neck 39: E29-E33, 2017. PMID- 27704667 TI - Quality of life following fistulotomy - short term follow-up. AB - AIM: Anal fistula causes pain and discharge of pus and blood. Treatment by fistulotomy has the highest success, but can risk continence; treatment needs to balance cure with continence. This study assessed the impact of fistulotomy on quality of life (QOL) and continence. METHOD: Patients selected for fistulotomy prospectively completed the St Mark's Continence Score (full incontinence = 24) and Short Form-36 questionnaires preoperatively at two institutions with an interest in anal fistula. Patients were reassessed 3 months' postoperatively. RESULTS: There were 52 patients with a median age of 44 (range 19-82) years; 10 were women. Preoperative continence scores were median 0 (range 0-23) and there was no significant difference compared with postoperative scores (median 1, range 0-24). Following fistulotomy QOL was significantly improved in four of eight domains - Bodily Pain (P < 0.001), Vitality (P < 0.01), Social Functioning (P < 0.05) and Mental Health (P < 0.001) - and returned to that of the general population. QOL for patients with intersphincteric fistula improved postfistulotomy, and for those with trans-sphincteric fistula it remained the same. Data were further examined in two groups, with and without deterioration in continence score. Where continence improved postoperatively, QOL improved in three domains; where continence deteriorated QOL improved in two domains (P < 0.05). Patients with postoperative continence scores of < 5 had worse QOL than those scoring 4 or less. CONCLUSION: QOL significantly improved at 3 months' follow-up after fistulotomy where continence was maintained or a small reduction occurred.

AB - High-performance electrical double-layer capacitors (EDLCs) require carbon electrode materials with high specific surface area, short ion-diffusion pathways, and outstanding electrical conductivity. Herein, a general approach combing the molten-salt method and chemical activation to prepare N-doped carbon nanosheets with high surface area (654 m2 g-1 ) and adjustable porous structure is presented. Owing to their structural features, the N-doped carbon nanosheets exhibited superior capacitive performance, demonstrated by a maximum capacitance of 243 F g-1 (area-normalized capacitance up to 37 MUF cm-2 ) at a current density of 0.5 A g-1 in aqueous electrolyte, high rate capability (179 F g-1 at 20 A g-1 ), and excellent cycle stability. This method provides a new route to prepare porous and heteroatom-doped carbon nanosheets for high-performance EDLCs, which could also be extended to other polymer precursors and even waste biomass.

AB - Despite a large body of research evaluating factors associated with the relapse of psychosis in schizophrenia, no studies in Pakistan have been undertaken to date to identify any such factors, including specific cultural factors pertinent to Pakistan. Semistructured interviews and psychometric measures were undertaken with 60 patients diagnosed with schizophrenia (49 male and 11 female) and their caregivers at four psychiatric hospitals in the Peshawar region in Pakistan. Factors significantly associated with psychotic relapse included treatment non adherence, comorbid active psychiatric illnesses, poor social support, and high expressed emotion in living environments (P < 0.05). The attribution of symptoms to social and cultural values (97%) and a poor knowledge of psychosis by family members (88%) was also prevalent. In addition to many well-documented factors associated with psychotic relapse, beliefs in social and cultural myths and values were found to be an important, and perhaps treatable, factor associated with relapse of psychosis in Pakistan. The provision of evidence-based psychotherapeutic interventions, such as behaviour and family therapy and cognitive behaviour therapy for psychosis, could potentially ameliorate the relapse rate of psychosis in Pakistan. PMID- 27704677 TI - Clinical interventions to reduce stillbirths in sub-Saharan Africa: a mathematical model to estimate the potential reduction of stillbirths associated with specific obstetric conditions. AB - OBJECTIVE: Stillbirths are among the most common adverse pregnancy outcomes, with 98% occurring in low-income countries. More than one-third occur in sub-Saharan Africa (SSA). However, the medical conditions causing stillbirths and interventions to reduce stillbirths from these conditions are not well documented. We estimated the reductions in stillbirths possible with combinations of interventions. DESIGN: We developed a computerised model to estimate the impact of various interventions on stillbirths caused by the most common conditions. The model considered the location of obstetric care (home, clinic or hospital) and each intervention's efficacy, penetration and utilisation. Maternal transfers were also considered. SETTING AND POPULATION: Pregnancies in SSA in 2012. METHODS: For each condition, we created a series of scenarios involving different combinations of interventions and modelled their impact on stillbirth rates. MAIN OUTCOME MEASURES: Stillbirths associated with various maternal and fetal conditions and the percentage reduction with various interventions. RESULTS: Eight to ten maternal and fetal conditions were responsible for most stillbirths, but none for more than 15%. The most common conditions causing stillbirths in SSA include obstructed labour and uterine rupture, fetal distress and umbilical cord complications, fetal growth restriction, pre eclampsia/eclampsia, and placental abruption/placenta praevia. Syphilis and malaria contribute smaller numbers. Reducing stillbirths requires appropriate diagnosis and management of each condition, usually including hospital care for monitoring and delivery, often by caesarean section. Maternal syphilis and malaria were the only conditions for which outpatient management alone reduced stillbirth. CONCLUSIONS: Most stillbirths in low-income countries occur at term and during labour and therefore are preventable by appropriate obstetric care. Management focused on the maternal and fetal conditions that cause stillbirths is necessary to achieve stillbirth rates approaching those found in high-income countries. TWEETABLE ABSTRACT: Reducing stillbirth incidence requires appropriate management of each causative condition and often caesarean delivery.

AB - BACKGROUND: The aim of this study was to verify the accuracy of anthropometric equations to estimate the body density (BD) of adults with Down syndrome (DS), and propose new regression equations. MATERIALS AND METHODS: Twenty-one males (30.5 +/- 9.4 years) and 17 females (27.3 +/- 7.7 years) with DS participated in this study. The reference method for BD was air displacement plethysmography (ADP). Also, the BD was estimated by anthropometric equations. The body fat percentage (BF %) was estimated by the Siri equation. RESULTS: For females, the Durnin and Womersley equation showed no difference from the ADP, but a trend of underestimation was observed. For males, all equations were significantly different for the BF % from ADP. The equations developed in this study showed a high correlation and acceptable agreement with BF % from ADP in both genders. CONCLUSION: All equations are not valid for DS adults. The new equations developed here were accurate in estimating the BF %.

AB - OBJECTIVE: To examine the relation between maternal vitamin D status and risk of pre-eclampsia and preterm birth in women at high risk for pre-eclampsia. DESIGN: Analysis of prospectively collected data and blood samples from a trial of prenatal low-dose aspirin. SETTING: Thirteen sites across the USA. POPULATION: Women at high risk for pre-eclampsia. METHODS: We measured 25-hydroxyvitamin D [25(OH)D] concentrations in stored maternal serum samples drawn at 12-26 weeks' gestation (n = 822). We used mixed effects models to examine the association between 25(OH)D and risk of pre-eclampsia and preterm birth, controlling for confounders including prepregnancy BMI and race. MAIN OUTCOME MEASURES: Pre eclampsia and preterm birth. RESULTS: Twelve percent of women were vitamin D deficient [25(OH)D <30 nmol/l]. Women with 25(OH)D <30 versus >=75 nmol/l had a 2.4-fold (95% CI 1.0-5.6) higher risk of early-onset pre-eclampsia (<35 weeks' gestation) after confounder adjustment. Women with 25(OH)D <50 nmol/l had a 1.8 fold (95% CI 1.0-3.2) increased risk of preterm birth at <35 weeks compared with women who had 25(OH)D >=75 nmol/l, which was driven by indicated preterm births at <35 weeks' gestation [25(OH)D <50 versus >=75 nmol/l adjusted RR 2.5 (95% CI 1.1-5.8)]. There was no association between vitamin D status and pre-eclampsia or preterm birth at <37 weeks. CONCLUSION: Maternal vitamin D status in the second trimester was inversely associated with risk of early-onset pre-eclampsia and preterm birth at <35 weeks in women at high risk for pre-eclampsia. TWEETABLE ABSTRACT: Vitamin D is inversely related to risk of pre-eclampsia and preterm birth at <35 weeks in high-risk pregnancies. PMID- 27704680 TI - Risk stratification using Bmi-1 and Snail expression is a useful prognostic tool for patients with upper tract urothelial carcinoma. AB - OBJECTIVES: To investigate the expression levels of E-cadherin, Snail, Twist and Bmi-1 in the human upper tract urothelial carcinoma, and to assess whether these factors could be prognostic markers. METHODS: Immunohistochemistry was carried out to determine the expression of E-cadherin, Snail, Twist and Bmi-1 in upper tract urothelial carcinoma samples from 144 patients that underwent total nephroureterectomy between January 1995 and December 2010. The patient population had a median age of 71 years, and comprised 104 men and 40 women, with a median follow-up period of 40 months. The prognostic value of these markers was assessed by univariate and multivariate analysis. A risk stratification analysis was carried out. RESULTS: Snail and Bmi-1 expression predicted worse overall survival (P = 0.0075 and 0.0035), cancer-specific survival (P = 0.0919 and 0.0085) and recurrence-free survival (P = 0.0360 and 0.0817, respectively) compared with tumors that lacked Snail and Bmi-1 expression. Additionally, clinical parameters, grade, stage and lymphovascular invasion correlated with overall survival, cancer specific survival and recurrence-free survival. Multivariate analysis showed that Bmi-1 expression was among the most significant factors in predicting cancer specific survival (P = 0.0333). The combination of Snail, Bmi-1 and pathological stage was the most useful prognostic biomarker for upper tract urothelial carcinoma. CONCLUSION: Risk stratification by epithelial-mesenchymal transition and cancer stem cell-regulated genes, such as Snail and Bmi-1, might be useful prognostic markers for upper tract urothelial carcinoma.

AB - BACKGROUND: Regarding the current approach, there is no evidence to show which treatment technique is the most accurate and useful in peri-implant defects. PURPOSE: The aim of this study is comparing the effect of porous titanium granule (PTG) with rotary titanium brush and the use of xenograft and collagen membrane in the treatment of intra-bony peri-implant defects. MATERIALS AND METHODS: Twenty-two patients, suffering peri-implantitis defects were included this study. Patients were divided into two groups: The PTG group used rotary titanium brush, PTG, and platelet rich fibrin (PRF) membrane. The XGF group used xenograft bone substitute, collagen membrane, and PRF membrane. Clinical measurements and cone beam computed tomography per region were recorded as baseline and sixth month after surgery. RESULTS: The mean CAL values were improved from 5.29 +/- 1.06 to 3.59 +/- 0.88 mm in PTG group, while in XGF group; these values were improved from 4.77 +/- 1.05 to 3.30 +/- 0.58 mm. Radiographic bone filling values displayed a statistically significant difference between of groups. In PTG groups, these radiological values increased more than the XGF group. CONCLUSIONS: PTG may be more appropriate for peri-implantitis surgery than xenograft due to inert structure and comfortable use of PTG to provide mechanical support for enlarging the surface area of the implant.

AB - BACKGROUND: Opportunities for community members to actively participate in policy development are increasing. Community/citizen's juries (CJs) are a deliberative democratic process aimed to illicit informed community perspectives on difficult topics. But how comprehensive these processes are reported in peer-reviewed literature is unknown. Adequate reporting of methodology enables others to judge process quality, compare outcomes, facilitate critical reflection and potentially repeat a process. We aimed to identify important elements for reporting CJs, to develop an initial checklist and to review published health and health policy CJs to examine reporting standards. DESIGN: Using the literature and expertise from CJ researchers and policy advisors, a list of important CJ reporting items was suggested and further refined. We then reviewed published CJs within the health literature and used the checklist to assess the comprehensiveness of reporting. RESULTS: CJCheck was developed and examined reporting of CJ planning, juror information, procedures and scheduling. We screened 1711 studies and extracted data from 38. No studies fully reported the checklist items. The item most consistently reported was juror numbers (92%, 35/38), while least reported was the availability of expert presentations (5%, 2/38). Recruitment strategies were described in 66% of studies (25/38); however, the frequency and timing of deliberations was inadequately described (29%, 11/38). CONCLUSIONS: Currently CJ publications in health and health policy literature are inadequately reported, hampering their use in policy making. We propose broadening the CJCheck by creating a reporting standards template in collaboration with international CJ researchers, policy advisors and consumer representatives to ensure standardized, systematic and transparent reporting. PMID- 27704687 TI - Diprosopus: Systematic review and report of two cases. AB - BACKGROUND: Diprosopus is a subtype of symmetric conjoined twins with one head, facial duplication and a single trunk. Diprosopus is a very rare congenital anomaly. METHODS: This is a systematic review of published cases and the presentation of two new cases born in Argentina. We estimated the prevalence of conjoined twins and diprosopus using data from the National Network of Congenital Anomalies of Argentina (RENAC). RESULTS: The prevalence of conjoined twins in RENAC was 19 per 1,000,000 births (95% confidence interval, 12-29). Diprosopus prevalence was 2 per 1,000,000 births (95% confidence interval, 0.2-6.8). In the systematic review, we identified 31 diprosopus cases. The facial structures more frequently duplicated were nose and eyes. Most frequent associated anomalies were: anencephaly, duplication of cerebral hemispheres, craniorachischisis, oral clefts, spinal abnormalities, congenital heart defects, diaphragmatic hernia, thoracic and/or abdominal visceral laterality anomalies. One of the RENAC cases and three cases from the literature had another discordant nonmalformed twin. CONCLUSION: The conjoined twins prevalence was similar to other studies. The prevalence of diprosopus was higher. The etiology is still unknown. The presence of visceral laterality anomalies may indicate the link between diprosopus and the alteration or duplication of the primitive node in the perigastrulation period (12-15 days postfertilization). Pregnancies of more than two embryos may be a risk factor for diprosopus. Given the low prevalence of this defect, it would be useful to perform studies involving several surveillance systems and international consortiums. Birth Defects Research (Part A), 2016.

AB - INTRODUCTION: Joint haemorrhage is the principal clinical manifestation of haemophilia frequently leading to advanced arthropathy and arthrofibrosis, resulting in severe disability. The degree and prevalence of arthrofibrosis in hemophilic arthropathy is more severe than in other forms of arthropathy. Expression of connective tissue growth factor (CTGF) has been linked to many fibrotic diseases, but has not been studied in the context of haemophilic arthropathy. AIM: We aim to compare synovial tissues histologically from haemophilia and osteoarthritis patients with advanced arthropathy in order to compare expression of proteins that are possibly aetiologic in the development of arthrofibrosis. METHODS: Human synovial tissues were obtained from 10 haemophilia and 10 osteoarthritis patients undergoing joint surgery and processed for histology and immunohistochemistry. RESULTS: All samples from haemophilia patients had synovitis with hypertrophy and hyperplasia of synovial villi. Histologically, synovial tissues contained hyperplastic villi with increased cellularity and abundant haemosiderin- and ferritin-pigmented macrophage-like cells (HMCs), with a perivascular localization in the sub-surface layer. CTGF staining was observed in the surface layer and sub-surface layer in all haemophilia patients, exclusively co-localizing with HMCs. Quantification showed that the extent of CTGF-positive areas was correlated with the degree of detection of HMCs. CTGF was not observed in any of the samples from osteoarthritis patients. CONCLUSION: Using histological analysis, we showed that CTGF expression is elevated in haemophilia patients with arthrofibrosis and absent in patients with osteoarthritis. Additionally, we found that CTGF is always associated with haemosiderin-pigmented macrophage-like cells, which suggests that CTGF is produced by synovial A cells following the uptake of blood breakdown products. PMID- 27704688 TI - FAK contributes to proteinuria in hypercholesterolaemic rats and modulates podocyte F-actin re-organization via activating p38 in response to ox-LDL. AB - Focal adhesion kinase (FAK) is a non-receptor protein tyrosine kinase that regulates cell adhesion, proliferation and differentiation. In the present study, a rat model of high fat diet-induced hypercholesterolaemia was established to investigate the involvement of FAK in lipid disorder-related kidney diseases. We showed focal fusion of podocyte foot process that occurred at as early as 4 weeks in rats consuming high fat diet, preceding the onset of proteinuria when aberrant phosphorylation of FAK was found. These abnormalities were ameliorated by dietary intervention of TAE226, a reported inhibitor of FAK. FAK is also an adaptor protein initiating cascades of intracellular signals including c-Src, Rho GTPase and mitogen-activated protein kinase (MAPK). P38 MAPK belongs to the latter and is centrally involved in kidney diseases. Our cell culture data revealed oxidized low-density lipoprotein (ox-LDL) triggered hyper-phosphorylation of FAK and p38, ectopic expression of cellular markers (manifested as decreased WT1, podocin and NEPH1, and increased vimentin and mmp9), and re-arrangement of F-actin filaments with enhanced cell motility; these mutations were significantly rectified by FAK shRNA. Notably, pre-treatment of p38 inhibitor did not alter FAK activation, albeit its deletion of p38 hyper-activity and attenuation of cellular abnormalities, demonstrating that p38 acted as a downstream effector of FAK signalling and ox-LDL damaged podocytes in a FAK/p38-dependent manner. This was further identified by animal data that p38 activation was also abrogated by TAE226 treatment in hypercholesterolaemic rats, suggesting that FAK/p38 axis might also be involved in in vivo events. These findings provided a potential early mechanism of hypercholesterolaemia-related podocyte damage and proteinuria. PMID- 27704693 TI - Structural Analysis and Application of n-Alkyl Cyanoacrylate Surgical Adhesives to the Fixation of Meshes for Hernia Repair. AB - The article deals with a comparative analysis of the parameters of the polymerization in physiological conditions of three commercially available alkyl cyanoacrylates, n-butyl cyanoacrylate (GLUBRAN 2), n-hexyl cyanoacrylate (IFABOND), and n-octyl cyanoacrylate (EVOBOND), the cell behavior of the corresponding polymers and the application of these adhesives in the fixation of surgical polypropylene meshes for hernia repair in an animal model of rabbits. The results obtained demonstrate that the curing process depends on the nature of the alkyl residue of the ester group of cyanoacrylate molecules, being the heat of polymerization lower for the octyl derivative in comparison with the hexyl and butyl, and reaching a maximum temperature of 35 degrees C after a time of mixing with physiological fluids of 60-70 s. The cell behavior demonstrates that the three systems do not present toxicity for fibroblasts and low adhesion of cells, which is a positive result for application as tissue adhesives, especially for the fixation of abdominal polypropylene meshes for hernia repair. The animal experimentation indicates the excellent tolerance of the meshes fixed with the cyanoacrylic adhesives, during at least a period of 90 d, and guarantees a good adhesion for the application of hernia repair meshes.

PMID- 27704696 TI - EBUS may arise as an initial time saving procedure in patients who are suspected to have small cell lung cancer. AB - BACKGROUND: Small cell lung cancer (SCLC) commonly presents as hilar/mediastinal masses. In some occasions, conventional flexible bronchoscopy fails and a substantial amount of time is lost until establishing the diagnosis. OBJECTIVE: The aim of the study was to demonstrate the superiority of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) compared to conventional methods in establishing the diagnosis as an initial modality as well as to point out the saved time until the diagnosis. METHODS: We retrospectively reviewed the patients who were diagnosed as SCLC by EBUS-TBNA between April 2010 and January 2016. The demographics of the patients, smoking history were all recorded. We also compared the time between the first computed tomography (1stCT) and first diagnostic procedure (1stDP), 1stDP and final diagnosis (FDx), 1stCT and FDx, and 1stDP and EBUS procedure were also compared. RESULTS: One hundred and thirty-three patients were included in the study. The diagnostic yield of EBUS-TBNA was 98.5%. The mean time between the 1stCT and 1stDP; 1stDP and FDx; 1stCT and FDx; 1stDP and EBUS procedure were 7.0 +/- 9.0; 11.8 +/- 16.1; 18.8 +/- 17.9; and 10.8 +/- 16.0 days, respectively. The time between 1stCT to 1stDP was not significantly different in patients with or without previous diagnostic procedures. However, the time between 1stDP to FDx and 1stCT to FDx were significantly higher in the patients with previous procedures (P < .001). The difference in time between 1stDP to FDx and 1stCT to FDx was also similar in patients with only hilar and/or mediastinal lesions (P = .001, P = .006, respectively). CONCLUSION: EBUS-TBNA may be an initial diagnostic procedure in SCLC. Patients with only hilar/mediastinal masses without any endobronchial lesion could be directed to centers with the capability for performing EBUS-TBNA to have a rapid diagnosis without any time loss. PMID- 27704697 TI - Carboxymethylinulin-Chitosan Nanoparticles for the Delivery of Antineoplastic Mitoxantrone. AB - Mitoxantrone (MTX) is an antineoplastic agent whose use is limited by serious side effects on non-neoplastic cells. The aim of this study was the development of a new drug release system using an ionotropic gelation technique for microencapsulation of MTX in chitosan-carboxymethylinulin nanoparticles (CCInp), followed by evaluation of their cytotoxic effects on neoplastic MDA-MB-231 and non-neoplastic NIH3T3 cell lines. The CCInp were prepared through a new reliable method for easy functionalization of both inulin and chitosan. Both unloaded and drug-loaded nanoparticles were characterized by transmission electron microscopy (TEM) and dynamic light scattering (DLS) and showed a spherical morphology with an average hydrodynamic diameter between 40 and 80 nm. Both nanoparticles were stable and easily degraded by lysozyme. MTX-loaded nanoparticles led to a greater mortality of MDA-MB-231 relative to free drug due to the ability of the nanoparticles to accumulate preferentially in neoplastic cells. The developed drug release system retains the ability to kill MDA-MB-231 cells in vitro, improving the survival of NIH3T3 cells. PMID- 27704695 TI - Weight loss after head and neck cancer: A dynamic relationship with depressive symptoms. AB - BACKGROUND: Weight loss and depressive symptoms are critical head and neck cancer outcomes, yet their relation over the illness course is unclear. METHODS: Associations between self-reported depressive symptoms and objective weight loss across the year after head and neck cancer diagnosis were examined using growth curve modeling techniques (n = 564). RESULTS: A reciprocal covariation pattern emerged-changes in depressive symptoms over time were associated with same-month changes in weight loss (t [1148] = 2.05; p = .041), and changes in weight loss were associated with same-month changes in depressive symptoms (t [556] = 2.43; p = .015). To the extent that depressive symptoms increased, patients lost incrementally more weight than was lost due to the passage of time and vice versa. Results also suggested that pain and eating-related quality of life might explain the reciprocal association between depressive symptoms and weight loss. CONCLUSION: In head and neck cancer, a transactional interplay between depressive symptoms and weight loss unfolds over time. (c) 2016 Wiley Periodicals, Inc. Head Neck 39: 370-379, 2017.

When they work properly, they are able to provide invaluable interpretations of experimental results and ultimately provide novel, experimentally testable predictions. Unfortunately, not all simulation models are created equal, and with inaccurate models it becomes unclear what is a bona fide prediction versus a simulation artifact. RNA models are still in their infancy compared to the many robust protein models that are widely in use, and for that reason the number of RNA force field revisions in recent years has been rapidly increasing. As there is no universally accepted 'best' RNA force field at the current time, RNA simulators must decide which one is most suited to their purposes, cognizant of its essential assumptions and their inherent strengths and weaknesses. Hopefully, armed with a better understanding of what goes inside the simulation 'black box,' RNA biochemists can devise novel experiments and provide crucial thermodynamic and structural data that will guide the development and testing of improved RNA models.

PMID- 27704699 TI - A Surfactant-Encapsulating Polyoxometalate Nanowire Assembly as a New Carrier for Nanoscale Noble-Metal Catalysts. AB - The loading of noble-metal nanoparticles (NMNPs) onto various carriers to obtain stable and highly efficient catalysts is currently an important strategy in the development of noble metal (NM)-based catalytic reactions and their applications. We herein report a nanowire supramolecular assembly constructed from the surfactant-encapsulating polyoxometalates (SEPs) CTAB-PW12 , which can act as new carriers for NMNPs. In this case, the Ag NPs are loaded onto the SEP nanowire assembly with a narrow size distribution from 5 to 20 nm in diameter; the average size is approximately 10 nm. The Ag NPs on the nanowire assemblies are well stabilized and the over agglomeration of Ag NPs is avoided owing to the existence of well-arranged polyoxometalate (POM) units in the SEP assembly and the hydrophobic surfactant on the surface of the nanowire assembly. Furthermore, the loading amount of the Ag NPs can be adjusted by controlling the concentration of the AgNO3 aqueous solution. The resultant Ag/CTAB-PW12 composite materials exhibit high activity and good stability for the catalytic reduction of 4 nitrophenol (4-NP) with NaBH4 in isopropanol/H2 O solution. The NMNPs-loaded SEP nanoassembly may represent a new composite catalyst system for application in NM based catalysis. PMID- 27704700 TI - Study of intra-racial exclusion within Australian Indigenous communities using eco-maps. AB - In Australia, 'indigeneity' is not determined by skin colour, but rather by a person's heritage, acceptance by an indigenous community, and active participation in the affairs of that indigenous community. Some people who identify as indigenous, however, have experienced 'colourism' - that is, experiences of social exclusion because of the colour of their skin - from non Indigenous and also Indigenous Australians. This paper describes research that explored the effect of intra-racial exclusion on the mental health and wellbeing of Indigenous Australians, with a particular focus on skin colour or 'manifest indigeneity'. Framed within a qualitative design, an eco-map was used to guide in depth interviews with 32 participants that gave rise to personal stories that described the distress of experiencing intra-racial colourism. Findings were derived from a thematic analysis that identified four major themes: 'Growing up black', 'Living on black country', 'Looking black', and 'Fitting in black'. These findings are important because they suggest a way forward for mental health nurses to better understand and support the mental health and wellbeing of Indigenous Australians who have experienced social exclusion as a result of colourism.

AB - Cupric oxide (CuO), a narrow-bandgap semiconductor, has a band alignment that makes it an ideal photocathode for the renewable production of solar fuels. However, the photoelectrochemical performance of CuO is limited by its poor conductivity and short electron diffusion lengths. Herein, a three-dimensional (3D) architecture consisting of CuO nanosheets supported onto transparent conducting macroporous antimony-doped tin oxide (mpATO@CuONSs) is designed as an excellent photocathode for promoting the hydrogen evolution reaction (HER). Owing to the 3D structure affording superior light-harvesting characteristics, large contact areas with the electrolyte, and highly conductive pathways for separation and transport of charge carriers, the mpATO@CuONSs photocathode produces an impressively high photocurrent density of -4.6 mA cm-2 at 0 V versus the reversible hydrogen electrode (RHE), which is much higher than that of the CuONSs array onto planar FTO glass (-1.9 mA cm-2 ).

This might have a negative impact upon their ability to understand patients' clinical conditions and nursing practice. We sought information about students' experiences with bioscience. A total of 126 final year nursing students completed a questionnaire. The findings showed that the majority of participants considered bioscience subjects to require more work compared to nursing subjects (65.9%), and that they would like a better understanding of bioscience (73.8%), but understood that bioscience forms the foundation of nursing practice (76.2%). Younger participants without secondary school science rated bioscience harder than nursing subjects and spent more time studying bioscience compared to older participants. Participants without any secondary school science lacked an ability to apply bioscience concepts to patient conditions. These results showed that nursing students, especially those without secondary school science, would benefit from improved bioscience integration with nursing practice. Nursing and bioscience educators should consider greater alignment of bioscience with nursing practice subjects, especially earlier in the curriculum. PMID- 27704703 TI - Umbilical lactate as a measure of acidosis and predictor of neonatal risk: a systematic review. AB - BACKGROUND: Umbilical cord lactate is one approach to measuring acidosis and intrapartum hypoxia, knowledge of which may be helpful for clinicians involved in the care of women and newborns. OBJECTIVE: To synthesise the evidence on accuracy of umbilical cord lactate in measuring acidosis and predicting poor neonatal outcome. SEARCH STRATEGY: Studies published and unpublished between 1990 and 2014 from PubMed/Medline, EMBASE, Cochrane Central Register of Controlled Trials, and clinicaltrials.gov were assessed. SELECTION CRITERIA: Cross-sectional and randomised studies that assessed fetal acidosis (using lactate as the index test) with or without an assessment of neonatal outcome. DATA COLLECTION AND ANALYSIS: Correlations between index and reference test(s) were recorded, as were the raw data to classify the predictive ability of umbilical lactate for neonatal outcomes. Meta-analysis of correlation was performed. We plotted estimates of the studies' observed sensitivities and specificities on Forest plots with 95% confidence intervals (CI). Where possible, we combined data using meta-analysis, applying the hierarchical summary receiver operating characteristics model and a bivariate model. MAIN RESULTS: Twelve studies were included. Umbilical lactate correlated with pH [pooled effect size (ES) -0.650; 95% CI -0.663 to -0.637, P < 0.001], base excess (ES -0.710; 95% CI -0.721 to -0.699, P < 0.001), and Apgar scores at 5 minutes (ES 0.300; 95% 0.193-0.407, P < 0.001). Umbilical lactate had pooled sensitivity and specificity for predicting neonatal neurological outcome including hypoxic ischaemic encephalopathy of 69.7% (95% CI 23.8-94.4%) and 93% (95% CI 86.8-96.3%). AUTHORS' CONCLUSION: Umbilical cord lactate is a clinically applicable, inexpensive and effective way to measure acidosis and is a tool that may be used in the assessment of neonatal outcome. TWEETABLE ABSTRACT: Umbilical cord lactate: a clinically applicable, inexpensive, effective way to measure intrapartum acidosis.

AB - Multiple endocrine neoplasia type 2 (MEN2) is an autosomal-dominant cancer syndrome with major components of medullary thyroid carcinoma, pheochromocytoma, and hyperparathyroidism. MEN2B is the most aggressive and rarest of the MEN2 variants. Pheochromocytoma in MEN2 is virtually always located in the adrenal medulla, but MEN2-associated extra-adrenal pheochromocytomas (paraganglioma) are rare. A 59-year-old man who has been diagnosed with MEN2B consulted our hospital for surgical treatment of a 10-mm left adrenal mass and a 30-mm retroperitoneal mass. He had paroxysmal elevations in blood pressure and in urinary metanephrine and vanillylmandelic acid values. Laparoscopic excision of the left adrenal gland and retroperitoneal mass was performed. We experienced an extremely rare case of composite paraganglioma-ganglioneuroma concomitant with adrenal metastasis of medullary thyroid carcinoma in a patient with MEN2B. PMID- 27704705 TI - The iron-sulfur cluster sensor IscR is a negative regulator of Spi1 type III secretion system in Salmonella enterica. AB - Iron-sulfur (Fe-S)-containing proteins contribute to various biological processes, including redox reactions or regulation of gene expression. Living organisms have evolved by developing distinct biosynthetic pathways to assemble these clusters, including iron sulfur cluster (ISC) and sulfur mobilization (SUF). Salmonella enterica serovar Typhimurium is an intracellular pathogen responsible for a wide range of infections, from gastroenteritis to severe systemic diseases. Salmonella possesses all known prokaryotic systems to assemble Fe-S clusters, including ISC and SUF. Because iron starvation and oxidative stress are detrimental for Fe-S enzyme biogenesis and because such environments are often met by Salmonella during its intracellular life, we investigated the role of the ISC and SUF machineries during the course of the infection. The iscU mutant, which is predicted to have no ISC system functioning, was found to be defective for epithelial cell invasion and for mice infection, whereas the sufBC mutant, which is predicted to have no SUF system functioning, did not present any defect. Moreover, the iscU mutant was highly impaired in the expression of Salmonella pathogenicity island 1 (Spi1) type III secretion system that is essential for the first stage of Salmonella infection. The Fe-S cluster sensor IscR, a transcriptional regulator matured by the ISC machinery, was shown to bind the promoter of hilD, which encodes the master regulator of Spi1. IscR was also demonstrated to repress hilD and subsequently Spi1 gene expression, consistent with the observation that an IscR mutant is hyper-invasive in epithelial cells. Collectively, our findings indicate that the ISC machinery plays a central role in Salmonella virulence through the ability of IscR to down-regulate Spi1 gene expression. At a broader level, this model illustrates an adaptive mechanism used by bacterial pathogens to modulate their infectivity according to iron and oxygen availability.

AB - Transparent and removable aligners represent an effective solution to correct various orthodontic malocclusions through minimally invasive procedures. An aligner-based treatment requires patients to sequentially wear dentition-mating shells obtained by thermoforming polymeric disks on reference dental models. An aligner is shaped introducing a geometrical mismatch with respect to the actual tooth positions to induce a loading system, which moves the target teeth toward the correct positions. The common practice is based on selecting the aligner features (material, thickness, and auxiliary elements) by only considering clinician's subjective assessments. In this article, a computational design and engineering methodology has been developed to reconstruct anatomical tissues, to model parametric aligner shapes, to simulate orthodontic movements, and to enhance the aligner design. The proposed approach integrates computer-aided technologies, from tomographic imaging to optical scanning, from parametric modeling to finite element analyses, within a 3-dimensional digital framework. The anatomical modeling provides anatomies, including teeth (roots and crowns), jaw bones, and periodontal ligaments, which are the references for the down streaming parametric aligner shaping. The biomechanical interactions between anatomical models and aligner geometries are virtually reproduced using a finite element analysis software. The methodology allows numerical simulations of patient-specific conditions and the comparative analyses of different aligner configurations. In this article, the digital framework has been used to study the influence of various auxiliary elements on the loading system delivered to a maxillary and a mandibular central incisor during an orthodontic tipping movement. Numerical simulations have shown a high dependency of the orthodontic tooth movement on the auxiliary element configuration, which should then be accurately selected to maximize the aligner's effectiveness. PMID- 27704707 TI - Evaluation of a new carbon/zirconia-based sorbent for the cleanup of food extracts in multiclass analysis of pesticides and environmental contaminants. AB - A novel carbon/zirconia-based material, SupelTM QuE Verde, was evaluated in a filter-vial dispersive solid-phase extraction cleanup of pork, salmon, kale, and avocado extracts for the residual analysis of 65 pesticides and 52 environmental contaminants (flame retardants, polychlorinated biphenyls, polybrominated diphenyl ethers, and polycyclic aromatic hydrocarbons) using low-pressure gas chromatography with tandem mass spectrometry. An amount of 180 mg sorbent per 0.6 mL extract in filter-vial dispersive solid-phase extraction cleanup was found the optimum in terms of achieving satisfactory removal of co-extractives and recoveries of analytes, especially for structurally planar compounds. For analytes partially retained by Verde, normalization to an internal standard resulted in 62-107% recoveries. Addition of Verde to primary secondary amine and C18 in cleanup resulted in 38% more removal of gas-chromatography-amenable co extractives in avocado, 30% in kale, 39% in salmon, and 50% in pork. The removal efficiency of co-extracted chlorophyll was 93% for kale and 64% for avocado based on ultraviolet-visible absorbance. The developed method was validated at three spiking levels (10, 25, and 100 ng/g), and 70-120% recoveries with <=20% relative standard deviation were achieved for 96 (83%) out of 117 analytes in pork, 79 (69%) in salmon, 71 (62%) in kale, and 75 (65%) in avocado. PMID- 27704708 TI - Method development for separating organic carbonates by ion-moderated high performance liquid chromatography. AB - An ion-moderated partition high-performance liquid chromatography method was developed for the separation and identification of common organic carbonates. The separation of organic carbonates was achieved on an ion exclusion column with an exchangeable hydrogen ion. An isocratic, aqueous mobile phase was used for elution and detection was performed with a refractive index detector. The developed method was validated for specificity, linearity, limits of detection and quantification, precision and accuracy. All calibration curves showed excellent linear regression (R2 > 0.9990) within the testing range. The limits of detection were 3.8-30.8 ppm for the analyzed carbonates. Improvements in the peak resolution of the chromatograms were achieved by decreasing the column temperature. Addition of the organic modifier, acetonitrile, to the eluent was found to have insignificant effects on the peak resolution. The developed method was demonstrated for analyzing organic carbonate components in the electrolyte system of a commercial lithium ion battery. PMID- 27704709 TI - Comparative evaluation of the impact of minimally invasive preparation vs. conventional straight-line preparation on tooth biomechanics: a finite element analysis. AB - Minimally invasive endodontics emphasizes preservation of a maximal amount of healthy tooth tissue. However, whether the tooth structure preserved by minimally invasive endodontics can maintain higher fracture resistance is unclear. This study aimed to compare the biomechanics on teeth after minimally invasive (MI) preparation and straight-line (SL) preparation using finite element analysis. Six finite element analysis models of a mandibular first molar were constructed and divided into two groups (MI and SL). Two loads of 250 N, one vertically stimulating the vertical masticatory force and the other given 45 degrees to the longitudinal axis of the tooth, were applied. Stresses in the teeth were calculated and analyzed. Under both vertical and 45 degrees loads, the greatest stresses were located at the margin of the cavities on the occlusal surfaces. The stress concentration areas of teeth with minimally invasive access cavities were smaller than those of teeth prepared with straight-line opening in coronal and cervical areas. The stress concentration points in the cervical areas increased with the increase of canal taper in the coronal third. Minimally invasive access preparation reduced the stress distribution in crown and cervical regions. A smaller taper cervical enlargement caused lower stress in the cervical region.

AB - INTRODUCTION: Women with inherited bleeding disorders are at increased risk for bleeding complications during pregnancy and the postpartum period, particularly postpartum haemorrhage (PPH). AIM: This retrospective study evaluates pregnancy management through the Inherited Bleeding Disorders Clinic of Southeastern Ontario, the clinical factors associated with pregnancy-related abnormal bleeding and assesses tranexamic acid use in the postpartum treatment of bleeding disorder patients. METHODS: A chart review of 62 pregnancies, from 33 women, evaluated patient characteristics (age, haemostatic factor levels) and delivery conditions (mode of delivery, postpartum treatment) in relation to abnormal postpartum bleeding. RESULTS: This cohort revealed increased risk of immediate PPH with increased age at delivery (mean age: 30.1 years with PPH, 26.5 years without PPH, P < 0.013), and birth by vaginal delivery (P < 0.042). Low von Willebrand factor (VWF) antigen or factor VIII (FVIII) in the third trimester was not associated with an increased risk of PPH; however, low VWF:RCo was associated with increased immediate PPH despite treatment with continuous factor infusion (P < 0.042). Women treated with tranexamic acid postpartum had less severe bleeding in the 6 week postpartum (P < 0.049) with no thrombotic complications. CONCLUSIONS: This study contributes to the growing body of work aimed at optimizing management of bleeding disorder patients through pregnancy and the postpartum period, showing patients are at a higher risk of PPH as they age. Risk factors such as low third trimester VWF:RCo have been identified. Treatment with tranexamic acid in the postpartum period is associated with a reduced incidence of abnormal postpartum bleeding. PMID- 27704715 TI - Higher-order structure of the 30-nm chromatin fiber revealed by cryo-EM. AB - Genomic DNA is hierarchically packaged into chromatin in eukaryotes. As a central level chromatin structure between nucleosomal arrays and higher order organizations, 30 nm chromatin fiber, and its dynamics play a crucial role in regulating DNA accessibility for gene transcription. However, despite extensive efforts over three decades, the higher-order structure of the 30 nm chromatin fiber remains unresolved and controversial. We have recently reconstituted the 30 nm chromatin fibers from 12 nucleosomal arrays in vitro in the presence of linker histone H1, and determined their cryo-EM structures at resolution of 11 A (Song et al., Science 344, 376-380). Here, we briefly reviewed the higher-order structure studies of chromatin fibers, mainly focusing on the insights from the cryo-EM structures we recently solved.

AB - The models used for modeling the airflow in the human airways are either 0 dimensional compartmental or full 3-dimensional (3D) computational fluid dynamics (CFD) models. In the former, airways are treated as compartments, and the computations are performed with several assumptions, thereby generating a low fidelity solution. The CFD method displays extremely high fidelity since the solution is obtained by solving the conservation equations in a physiologically consistent geometry. However, CFD models (1) require millions of degrees of freedom to accurately describe the geometry and to reduce the discretization errors, (2) have convergence problems, and (3) require several days to simulate a few breathing cycles. In this paper, we present a novel, fast-running, and robust quasi-3D wire model for modeling the airflow in the human lung airway. The wire mesh is obtained by contracting the high-fidelity lung airway surface mesh to a system of connected wires, with well-defined radii. The conservation equations are then solved in each wire. These wire meshes have around O(1000) degrees of freedom and hence are 3000 to 25 000 times faster than their CFD counterparts. The 3D spatial nature is also preserved since these wires are contracted out of the actual lung STL surface. The pressure readings between the 2 approaches showed minor difference (maximum error = 15%). In general, this formulation is fast and robust, allows geometric changes, and delivers high-fidelity solutions. Hence, this approach has great potential for more complicated problems including modeling of constricted/diseased lung sections and for calibrating the lung flow resistances through parameter inversion. PMID- 27704717 TI - Extracapsular dissection versus superficial parotidectomy in benign parotid gland tumors: The Vienna Medical School experience. AB - BACKGROUND: The purpose of this study was to evaluate the clinical outcome in patients with benign parotid gland tumors after extracapsular dissection or superficial parotidectomy (SP). METHODS: Eight hundred ninety-four patients with primary pleomorphic adenoma or Warthin's tumor were included from this study. Type and length of surgery, tumor size, resection margins, and complication rates were assessed. RESULTS: Three hundred ninety-five (44.2%) extracapsular dissections and 499 SPs (55.8%) were performed. The rate of positive margins was significantly higher in the extracapsular dissection compared to the SP group (29.4% vs 10.2%; p < .0001). Recurrent disease (extracapsular dissection = 7.2% vs SP = 2.2%; p = .0003) and permanent facial palsy were significantly more frequent after extracapsular dissection than SP (2.2% vs 0.6%; p = .0396). Significant prolonged surgery time was observed after SP (146 vs 94 minutes; p < .0001). CONCLUSION: Because extracapsular dissection led to a significantly higher percentage of permanent facial palsy, recurrent disease, and positive resection margins compared to SP, we recommend SP for treating benign parotid gland tumors.

PMID- 27704719 TI - The Science of Salt: A Regularly Updated Systematic Review of the Implementation of Salt Reduction Interventions (November 2015 to February 2016). AB - The objective of this periodic review was to identify, summarize, and appraise studies relating to the implementation of salt reduction strategies that were retrieved between November 2015 and February 2016. From the established MEDLINE search, 56 studies were identified as relevant to the implementation of salt reduction initiatives. Detailed appraisal was performed on seven studies that evaluated the impact of salt reduction interventions. While study quality varied, all had one or more risks related to bias. There was consistent evidence, from three studies, demonstrating that setting-based structural interventions to improve the nutritional composition of foods were effective in reducing salt but mixed evidence in relation to the effectiveness of behavioral interventions. The development of an evaluation guidance framework that supports scientific rigor and external validity would aid future design and interpretation of studies evaluating salt reduction interventions, particularly for low-resource countries. PMID- 27704718 TI - HYDAMTIQ, a selective PARP-1 inhibitor, improves bleomycin-induced lung fibrosis by dampening the TGF-beta/SMAD signalling pathway. AB - Idiopathic pulmonary fibrosis is a severe disease characterized by excessive myofibroblast proliferation, extracellular matrix and fibrils deposition, remodelling of lung parenchyma and pulmonary insufficiency. Drugs able to reduce disease progression are available, but therapeutic results are unsatisfactory; new and safe treatments are urgently needed. Poly(ADP-ribose) polymerases-1 (PARP 1) is an abundant nuclear enzyme involved in key biological processes: DNA repair, gene expression control, and cell survival or death. In liver and heart, PARP-1 activity facilitates oxidative damage, collagen deposition and fibrosis development. In this study, we investigated the effects of HYDAMTIQ, a potent PARP-1 inhibitor, in a murine model of lung fibrosis. We evaluated the role of PARP on transforming growth factor-beta (TGF-beta) expression and TGF-beta/SMAD signalling pathway in lungs. Mice were intratracheally injected with bleomycin and then treated with either vehicle or different doses of HYDAMTIQ for 21 days. Airway resistance to inflation and lung static compliance, markers of lung stiffness, were assayed. Histochemical and biochemical parameters to evaluate TGF beta/SMAD signalling pathway with alpha-smooth muscle actin (alphaSMA) deposition and the levels of a number of inflammatory markers (tumour necrosis factor-alpha, interleukin-1beta, iNOS and COX-2) were performed. Bleomycin administration increased lung stiffness. It also increased lung PARP activity, TGF-beta levels, pSMAD3 expression, alphaSMA deposition and content of inflammatory markers. HYDAMTIQ attenuated all the above-mentioned physiological, biochemical and histopathological markers. Our findings support the proposal that PARP inhibitors could have a therapeutic potential in reducing the progression of signs and symptoms of the disease by decreasing TGF-beta expression and the TGF-beta/SMAD transduction pathway.

AB - aurora B kinase is highly expressed in several cancer cells and promotes tumorigenesis and progression, and therefore, it is an important target for drug to treat tumors. Quercetin was identified to be an antitumor agent. Herein, we report for the first time that quercetin inhibited aurora B activities by directly binding with aurora B in vitro and in vivo. Ex vivo studies showed that quercetin inhibited aurora B activities in JB6 Cl41 cells and A549 lung cancer cells. Moreover, knockdown of aurora B in A549 cells decreased their sensitivities to quercetin. In vivo study demonstrated that injection of quercetin in A549 tumor-bearing mice effectively suppressed cancer growth. The phosphorylation of histone 3 in tumor tissues was also decreased after quercetin treatment. In short, quercetin can suppress growth of lung cancer cells as an aurora B inhibitor both in vitro and in vivo.

AB - Maintenance of the gut epithelial integrity under stressful environments requires epithelial cells to rapidly elicit changes in gene expression patterns to regulate their survival, adapt to stress, and keep epithelial homeostasis. Disruption of the intestinal epithelial integrity occurs commonly in patients with various critical illnesses, leading to the translocation of luminal toxic substances and bacteria to the blood stream. Recently, noncoding RNAs (ncRNAs) have emerged as a novel class of master regulators of gene expression and are fundamentally involved in many aspects of gut mucosal regeneration, protection, and epithelial barrier function. Here, we highlight the roles of several intestinal epithelial tissue-specific microRNAs, including miR-222, miR-29b, miR 503, and miR-195, and long ncRNAs such as H19 and SPRY4-IT1 in the regulation of cell proliferation, apoptosis, migration, and cell-to-cell interactions and also further analyze the mechanisms through which ncRNAs and their interactions with RNA-binding proteins modulate the stability and translation of target mRNAs.

PMID- 27704723 TI - Drospirenone-containing combined oral contraceptives and the risk of arterial thrombosis: a population-based nested case-control study. AB - OBJECTIVE: To compare the rate of arterial thromboembolism (ATE) of drospirenone containing COCs to that of levonorgestrel-containing COCs. DESIGN: Population based cohort study. SETTING: United Kingdom's Clinical Practice Research Datalink (CPRD), which contains clinical records for >11 million patients. POPULATION: Women aged 16-45 years prescribed a drospirenone- or levonorgestrel-containing COC between May 2002 and June 2012. METHODS: We conducted nested case-control analyses using risk set sampling to randomly select up to 10 controls for each ATE case, matched on age, cohort entry year, CPRD registration year, COC user type (first-time ever, new, switcher, or prevalent users), duration of COC use, duration of progestin-only or implantable contraceptive use, pre-cohort entry duration of drospirenone and levonorgestrel use, and duration of follow up. MAIN OUTCOME MEASURES: We used conditional logistic regression to estimate hazard ratios and 95% confidence intervals (CIs), adjusted for high-dimensional propensity scores. RESULTS: Our cohort included 339 743 women followed over a mean 4.4 years, during which 228 ATE cases occurred: 37 myocardial infarctions, 170 strokes, and 21 other ATEs; overall rate: 1.5 events per 10 000 person-years (PYs). After adjusting for potential confounders, the hazard ratio for ATE with current use of drospirenone-containing COCs versus current use of levonorgestrel containing COCs was 0.89 (95% CI 0.35, 2.28), corresponding to a rate difference of -0.16 events per 10 000 PYs. CONCLUSIONS: The overall rate of ATE in this population is low regardless of which COC was taken. We found little evidence of a difference in the rate of ATE with drospirenone- versus levonorgestrel containing COCs. TWEETABLE ABSTRACT: Little evidence was found of a greater incidence of arterial thrombosis with drospirenone versus levonorgestrel contraceptives. PMID- 27704725 TI - The efficacy of valganciclovir for prevention of infections with cytomegalovirus and Epstein-Barr virus after kidney transplant in children. AB - This study evaluated the efficacy of prophylactic ValGCV in preventing CMV and EBV infections in a single-center pediatric kidney transplant population (2008 2014). Therapy duration was determined according to donor/recipient serostatus. EBV monitoring was performed using monthly plasma PCR for 18 months post transplant and for CMV, monthly for 6 months after prophylaxis cessation. Data were collected on 35 children, median age 10.6 years. There were 15 (42.9%) and 11 (31.4%) recipients seronegative for CMV or EBV, respectively, who received a kidney from a seropositive donor. Prophylaxis was ceased by 6 months in 24 (69%), between seven and 13 months in 10 (29%) children. Fourteen (40%) and eight (23%) children experienced CMV and EBV DNAemia, respectively. Ten of the 14 (71%) episodes of CMV DNAemia occurred in the first 6 months following cessation of prophylaxis. Shorter prophylaxis was associated with increased CMV DNAemia (P = 0.044). There was an inverse correlation between adjusted ValGCV dose and EBV incidence/timing. Neutropenia was more common if ValGCV dosage was >=10% of the dose predicted (by BSA and creatinine clearance). ValGCV prevents CMV and may modify EBV infection risk. Frequent dosing adjustment for BSA and creatinine clearance is required to optimize safety and efficacy. PMID- 27704729 TI - Antibiotic Control Policies in South Korea, 2000-2013. AB - Antibiotic stewardship is a key strategy for limiting antibiotic resistance. Over the last decade the South Korean government has implemented a series of healthcare policies directed to this end, consisting of legislative separation of drug prescribing and dispensing, antibiotic utilization reviews, healthcare quality assessment, and public reporting. As a result, the proportion of antibiotic prescriptions for acute upper respiratory tract infections in primary healthcare facilities decreased from 72.9% in 2002 to 42.7% in 2013. However, no significant decrease in antibiotic resistance occurred over the same period in clinically important bacteria such as Streptococcus pneumoniae. These government driven policies played a pivotal role in improving antibiotic use for outpatients and surgical patients in South Korea. However, to achieve long-lasting successful outcomes, coordinated efforts and communications among the stakeholders, including physicians and medical societies, are needed. PMID- 27704726 TI - Sera of patients with spontaneous tumour regression and elevated anti-CA I autoantibodies change the gene expression of ECM proteins. AB - Spontaneous tumour regression after high-dose therapy and autologous stem cell transplantation is associated with the aplastic anaemia-like syndrome and the presence of polyclonal autoantibodies against carbonic anhydrase I (CA I). When tumour cells were grown in vitro in the presence of patients' sera positive for anti-CA I autoantibodies, their morphological pattern was altered. These changes were accompanied by modifications in the gene expression profile. We observed downregulation of genes of the basal lamina assembly (collagen type IV alpha 4, the laminin subunit gamma 2), the extracellular matrix (collagen type I alpha 1), the cytoskeleton (keratin 14 type I), the collagen triple helix repeat containing 1 and the proto-oncogene WNT7B. On the other hand, the expression of the CA 1 gene was increased in the tumour cells. It was also noticed that the presence of anti-CA I autoantibodies did not impair tumour cell proliferation and cell viability in vitro. These findings were observed only in the presence of patients' sera positive for anti-CA I autoantibodies. PMID- 27704730 TI - Extended-spectrum beta-Lactamase-producing Enterobacteriaceae as a Common Cause of Urinary Tract Infections in Sri Lanka. AB - BACKGROUND: Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL PE) are increasingly reported as pathogens in urinary tract infections (UTIs). However, in Sri Lanka, the clinical and molecular epidemiology of ESBL-PE implicated in UTIs has not been well described. MATERIALS AND METHODS: We conducted prospective, laboratory-based surveillance from October to December 2013 at a tertiary care hospital in southern Sri Lanka and enrolled patients >=1 year of age with clinically relevant UTIs due to ESBL-PE. Isolate identity, antimicrobial drug susceptibility, and ESBL production were determined. Presence of beta-lactamase genes, bla(SHV), bla(TEM), and bla(CTX-M), was identified by polymerase chain reaction. RESULTS: During the study period, Enterobacteriaceae were detected in 184 urine samples, with 74 (40.2%) being ESBL producers. Among 47 patients with ESBL-PE who had medical records available, 38 (80.9%) had clinically significant UTIs. Most UTIs (63.2%) were community acquired and 34.2% were in patients with diabetes. Among 36 cultured ESBL-PE isolates, significant susceptibility (>80%) was only retained to amikacin and the carbapenems. The group 1 bla(CTX-M) gene was present in 90.0% of Escherichia coli isolates and all Klebsiella pneumoniae and Enterobacter cloacae isolates. The bla(SHV) and bla(TEM) genes were more common in K. pneumoniae (75% and 50%) and E. cloacae (50% and 50%) isolates than in E. coli (10% and 20%) isolates, respectively. CONCLUSION: The majority of UTIs caused by ESBL-PE were acquired in the community and due to organisms carrying the group 1 CTX-M beta-lactamase. Further epidemiologic studies of infections due to ESBL-PE are urgently needed to better prevent and treat these infections in South Asia.

AB - The efficacy and safety of a single tablet regimen (STR) of elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) were analyzed in Phase 3 clinical trials in antiretroviral therapy (ART)-naive and ART-experienced Asian subjects infected with human immunodeficiency virus (HIV)-1. Studies GS-US-236-102 and GS-US-236-103 were randomized, double-blind, placebo-controlled, 144-week studies conducted in ART-naive subjects, comparing E/C/F/TDF versus efavirenz (EFV)/F/TDF or ritonavir-boosted atazanavir (ATV+RTV) plus emtricitabine/tenofovir DF (F/TDF), respectively. Studies GS-US-236-115 and GS-US-236-121 were randomized, open-label, 96-week long conducted in ART experienced subjects, who switched to E/C/F/TDF from ritonavir-boosted protease inhibitors (PI+RTV)+F/TDF, or non-nucleoside reverse transcriptase inhibitors (NNRTI)+F/TDF regimens. The E/C/F/TDF appeared to have sustained efficacy and safety and was well tolerated in the small number of ART-naive and ART experienced Asian subjects.

AB - Increased detection of thyroid nodules using high-resolution ultrasonography has resulted in a world-wide increase in the incidence of differentiated thyroid cancer (DTC). Despite the steep increase in its incidence, the age-standardized mortality rate of thyroid cancer has remained stable, which leads toward a trend of more conservative treatment. The latest American Thyroid Association (ATA) guidelines for thyroid nodules and thyroid cancer revised in 2015 suggested that fine needle aspiration biopsy should be performed for thyroid nodules larger than 1 cm and lobectomy might be sufficient for 1 to 4 cm intrathyroidal DTC. In addition, active surveillance instead of immediate surgical treatment was also recommended as a treatment option for papillary thyroid microcarcinoma based on the results of a few observational studies from Japan. The Korean Thyroid Association (KTA) has organized a task force team to develop revised guidelines for thyroid nodules and DTC after an extensive review of articles and intense discussion on whether we should accept the changes in the 2015 ATA guidelines. This paper introduces and discusses the updated major issues and differences in the ATA and the KTA guidelines.

AB - BACKGROUND: Previous studies have reported that glypican-4 (GPC4) regulates insulin signaling by interacting with insulin receptor and through adipocyte differentiation. However, GPC4 has not been studied with regard to its effects on clinical factors in patients with type 2 diabetes mellitus (T2DM). We aimed to identify factors associated with GPC4 level in T2DM. METHODS: Between January 2010 and December 2013, we selected 152 subjects with T2DM and collected serum and plasma into tubes pretreated with aprotinin and dipeptidyl peptidase-4 inhibitor to preserve active gastric inhibitory polypeptide (GIP) and glucagon like peptide 1 (GLP-1). GPC4, active GLP-1, active GIP, and other factors were measured in these plasma samples. We performed a linear regression analysis to identify factors associated with GPC4 level. RESULTS: The subjects had a mean age of 58.1 years, were mildly obese (mean body mass index [BMI], 26.1 kg/m2), had T2DM of long-duration (mean, 101.3 months), glycated hemoglobin 7.5%, low insulin secretion, and low insulin resistance (mean homeostatic model assessment of insulin resistance [HOMA-IR], 1.2). Their mean GPC4 was 2.0+/-0.2 ng/mL. In multivariate analysis, GPC4 was independently associated with age (beta=0.224, P=0.009), and levels of active GLP-1 (beta=0.171, P=0.049) and aspartate aminotransferase (AST; beta=-0.176, P=0.043) after being adjusted for other clinical factors. CONCLUSION: GPC4 was independently associated with age, active GLP-1, and AST in T2DM patients, but was not associated with HOMA-IR and BMI, which are well known factors related to GPC4. Further study is needed to identify the mechanisms of the association between GPC4 and basal active GLP-1 levels.

PMID- 27704742 TI - Response: The Effects of High Fat Diet and Resveratrol on Mitochondrial Activity of Brown Adipocytes (Endocrinol Metab 2016;31:328-35, Cheol Ryong Ku et al.). PMID- 27704744 TI - Influence of low protein diets on gene expression of digestive enzymes and hormone secretion in the gastrointestinal tract of young weaned piglets. AB - To investigate dietary protein level effects on digestive mechanisms, weaned piglets were fed for 45 d with diets containing 20%, 17%, or 14% crude protein (CP) supplemented to meet requirements for essential amino acids. This article describes the influence of dietary protein on gastrointestinal hormones and expression of an array of digestive enzymes in the gastrointestinal tract and pancreas. Results indicated that there were no significant differences in expression of enzymes involved in carbohydrate digestion, except for maltase in the duodenum. In the jejunum, amylase expression in pigs fed 20% CP was much higher than that in pigs fed other diets (P<0.05) and maltase expression in those fed 17% CP was higher than that in other treatments (P<0.05). Although there were no remarkable differences in expression of aminopeptidase in the small intestine or carboxypeptidase in the pancreas (P>0.05), there was a trend towards higher expression of various proteases in pigs fed 17% CP. The duodenal expression of enteropeptidase in diets with 14% and 17% CP was significantly higher than that with 20% CP (P<0.05), but treatment differences did not existed in jejunum (P>0.05). The expression of GPR93 as a nutrient-responsive G protein-coupled receptor in 14% and 17% CP diets was significantly higher than that in 20% CP diet in the small intestine (P<0.05). The expressions of genes for pancreatic enzymes, lipase and elastase, were significantly higher in pigs fed diets with low CP, while similar trends occurred for carboxypeptidase, chymotrypsin and amylase. Conversely, the gastric expressions of pepsinogen A and progastricsin were lower with the 17% CP diet. Differences between treatments were found in the gastric antral contents of cholecystokinin and somatostatin: both increased in pigs fed 17% CP, accompanied by decreased content of motilin, which was also seen in plasma concentrations. These patterns were not reflected in duodenal contents. In general, 17% dietary CP was beneficial to the digestion of nutrient substance in the gastrointestinal tract. PMID- 27704743 TI - Research progress of the role and mechanism of extracellular signal-regulated protein kinase 5 (ERK5) pathway in pathological pain. AB - Extracellular signal-regulated protein kinase 5 (ERK5), also known as big mitogen activated protein kinase 1 (MAPK1), is an important member of ERK family, which is a subfamily of the large MAPK family. ERK5 is expressed in many tissues, including the dorsal root ganglion (DRG) neurons and the spinal cord. In this review, we focus on elaborating ERK5-associated pathway in pathological pain, in which the ERK5/CREB (cyclic adenosine monophosphate (cAMP)-response element binding protein) pathway plays a crucial role in the transduction of pain signal and contributes to pain hypersensitivity. ERK5 activation in the spinal dorsal horn occurs mainly in microglia. The activation of ERK5 can be mediated by N methyl-D-aspartate (NMDA) receptors. We also elaborate the relationship between ERK5 activation and nerve growth factor-tyrosine kinase A (NGF-TrkA), and the connection between ERK5 activation and brain-derived neurotrophic factor (BDNF) in pathological pain in detail. PMID- 27704745 TI - Effects of yeast products on the intestinal morphology, barrier function, cytokine expression, and antioxidant system of weaned piglets. AB - The goal of this study was to evaluate the effects of a mixture of yeast culture, cell wall hydrolysates, and yeast extracts (collectively "yeast products," YP) on the performance, intestinal physiology, and health of weaned piglets. A total of 90 piglets weaned at 21 d of age were blocked by body weight, sex, and litter and randomly assigned to one of three treatments for a 14-d feeding experiment, including (1) a basal diet (control), (2) 1.2 g/kg of YP, and (3) 20 mg/kg of colistin sulfate (CSE). No statistically significant differences were observed in average daily feed intake, average daily weight gain, or gain-to-feed ratio among CSE, YP, and control piglets. Increased prevalence of diarrhea was observed among piglets fed the YP diet, whereas diarrhea was less prevalent among those fed CSE. Duodenal and jejunal villus height and duodenal crypt depth were greater in the control group than they were in the YP or CSE groups. Intraepithelial lymphocytes (IEL) in the duodenal and jejunal villi were enhanced by YP, whereas IEL in the ileal villi were reduced in weaned piglets fed YP. Secretion of jejunal and ileal interleukin-10 (IL-10) was higher and intestinal and serum antioxidant indexes were affected by YP and CSE. In YP- and CSE-supplemented animals, serum D-lactate concentration and diamine oxidase (DAO) activity were both increased, and intestinal mRNA expressions of occludin and ZO-1 were reduced as compared to the control animals. In conclusion, YP supplementation in the diets of weaned piglets appears to increase the incidence of diarrhea and has adverse effects on intestinal morphology and barrier function. PMID- 27704746 TI - A genome-wide analysis of the ASYMMETRIC LEAVES2/LATERAL ORGAN BOUNDARIES (AS2/LOB) gene family in barley (Hordeum vulgare L.). AB - ASYMMETRIC LEAVES2/LATERAL ORGAN BOUNDARIES (AS2/LOB) genes are a family of plant specific transcription factors, which play an important role in the regulation of plant lateral organ development and metabolism. However, a genome-wide analysis of the AS2/LOB gene family is still not available for barley. In the present study, 24 AS2-like (ASL)/LOB domain (LBD) genes were identified based on the barley (Hordeum vulgare L.) genome sequence. A phylogenetic tree of ASL/LBD proteins from barley, Arabidopsis, maize, and rice was constructed. The ASL/LBD genes were classified into two classes, class I and class II, which were divided into five and two subgroups, respectively. Genes homologous in barley and Arabidopsis were analyzed. In addition, the structure and chromosomal locations of the genes were analyzed. Expression profiles indicated that barley HvASL/LBD genes exhibit a variety of expression patterns, suggesting that they are involved in various aspects of physiological and developmental processes. This genome-wide analysis of the barley AS2/LOB gene family contributes to our understanding of the functions of the AS2/LOB gene family. PMID- 27704747 TI - Effects of a controlled-release fertilizer on yield, nutrient uptake, and fertilizer usage efficiency in early ripening rapeseed (Brassica napus L.). AB - BACKGROUND: Nitrogen (N), phosphorous (P), and potassium (K) are critical nutrient elements necessary for crop plant growth and development. However, excessive inputs will lead to inefficient usage and cause excessive nutrient losses in the field environment, and also adversely affect the soil, water and air quality, human health, and biodiversity. METHODS: Field experiments were conducted to study the effects of controlled-release fertilizer (CRF) on seed yield, plant growth, nutrient uptake, and fertilizer usage efficiency for early ripening rapeseed (Xiangzayou 1613) in the red-yellow soil of southern China during 2011-2013. It was grown using a soluble fertilizer (SF) and the same amounts of CRF, such as SF1/CRF1 (3750 kg/hm2), SF2/CRF2 (3000 kg/hm2), SF3/CRF3 (2250 kg/hm2), SF4/CRF4 (1500 kg/hm2), SF5/CRF5 (750 kg/hm2), and also using no fertilizer (CK). RESULTS: CRF gave higher seed yields than SF in both seasons by 14.51%. CRF4 and SF3 in each group achieved maximum seed yield (2066.97 and 1844.50 kg/hm2, respectively), followed by CRF3 (1929.97 kg/hm2) and SF4 (1839.40 kg/hm2). There were no significant differences in seed yield among CK, SF1, and CRF1 (P>0.05). CRF4 had the highest profit (7126.4 CNY/hm2) and showed an increase of 12.37% in seed yield, and it decreased by 11.01% in unit fertilizer rate compared with SF4. The branch number, pod number, and dry matter weight compared with SF increased significantly under the fertilization of CRF (P<0.05). The pod number per plant was the major contributor to seed yield. On the other hand, the N, P, and K uptakes increased at first and then decreased with increasing the fertilizer rate at maturity, and the N, P, and K usage efficiency decreased with increasing the fertilizer rate. The N, P, and K uptakes and usage efficiencies of the CRF were significantly higher than those of SF (P<0.05). The N accumulation and N usage efficiency of CRF increased by an average of 13.66% and 9.74 percentage points, respectively, compared to SF. In conclusion, CRF significantly promoted the growth of rapeseed with using total N as the base fertilizer, by providing sufficient N in the later growth stages, and last by reducing the residual N in the soil and increasing the N accumulation and N usage efficiency. PMID- 27704748 TI - A study revealing the key aroma compounds of steamed bread made by Chinese traditional sourdough. AB - Aroma of Chinese steamed bread (CSB) is one of the important parameters that determines the overall quality attributes and consumer acceptance. However, the aroma profile of CSB still remains poorly understood, mainly because of relying on only a single method for aroma extraction in previous studies. Therefore, the objective of this study was to determine the volatile aroma compounds of five different samples of CSB using three different aroma extraction methods, namely solid-phase microextraction (SPME), simultaneous distillation-extraction (SDE), and purge and trap (P&T). All samples showed a unique aroma profile, which could be attributed to their unique microbial consortia. (E)-2-Nonenal and (E,E)-2,4 decadienal were the most prevalent aromatic compounds revealed by SDE, which have not been reported previously, while ethanol and acetic acid proved to be the most dominant compounds by both SPME and P&T. Our approach of combining three different aroma extraction methods provided better insights into the aroma profile of CSB, which had remained largely unknown in previous studies.

AB - The clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR associated protein 9 (Cas9) system is an adaptive immune defense system that resists the invasion of viruses and plasmids heterologous genetic material in bacteria and archaea. Taking the literature related to gene editing technology of CRISPR/Cas9 from the Web of Science database from 2002 to 2015, we use the software CiteSpaceV to analyze co-cited literature in order to establish the research hotspots and fronts recently in this field by knowledge mapping. PMID- 27704750 TI - Detection of biological thiols based on a colorimetric method. AB - Biological thiols (biothiols), an important kind of functional biomolecules, such as cysteine (Cys) and glutathione (GSH), play vital roles in maintaining the stability of the intracellular environment. In past decades, studies have demonstrated that metabolic disorder of biothiols is related to many serious disease processes and will lead to extreme damage in human and numerous animals. We carried out a series of experiments to detect biothiols in biosamples, including bovine plasma and cell lysates of seven different cell lines based on a simple colorimetric method. In a typical test, the color of the test solution could gradually change from blue to colorless after the addition of biothiols. Based on the color change displayed, experimental results reveal that the percentage of biothiols in the embryonic fibroblast cell line is significantly higher than those in the other six cell lines, which provides the basis for the following biothiols-related study. PMID- 27704752 TI - Direct Observation of Conducting Filaments in Tungsten Oxide Based Transparent Resistive Switching Memory. AB - Transparent nonvolatile memory has great potential in integrated transparent electronics. Here, we present highly transparent resistive switching memory using stoichiometric WO3 film produced by cathodic electrodeposition with indium tin oxide electrodes. The memory device demonstrates good optical transmittance, excellent operative uniformity, low operating voltages (+0.25 V/-0.42 V), and long retention time (>104 s). Conductive atomic force microscopy, ex situ transmission electron microscopy, and X-ray photoelectron spectroscopy experiments directly confirm that the resistive switching effects occur due to the electric field-induced formation and annihilation of the tungsten-rich conductive channel between two electrodes. Information on the physical and chemical nature of conductive filaments offers insightful design strategies for resistive switching memories with excellent performances. Moreover, we demonstrate the promising applicability of the cathodic electrodeposition method for future resistive memory devices. PMID- 27704751 TI - Identification of FECH gene multiple variations in two Chinese patients with erythropoietic protoporphyria and a review. AB - Erythropoietic protoporphyria (EPP), an autosomal dominant disease, is caused by partial deficiency of ferrochelatase (FECH), which catalyzes the terminal step of heme biosynthesis because of loss-of-function mutations in the FECH gene. To date, only a few cases have been described in Asia. In this study, we describe the clinical features of two Chinese patients with EPP, with diagnosis confirmed by the increase of free protoporphyrin in erythrocytes, detection of plasma fluorescence peak at 630-634 nm, and analysis of FECH gene mutations. Using gene scanning, we identified a small deletion in the FECH gene (c.973 delA) in one proband (patient A) and a pathogenic FECH mutation (c.1232 G>T) in the other (patient B) and also observed some nucleotide variations (c.798 C>G, c.921 A>G, IVS1-23 C>T, IVS3+23 A>G, IVS9+35 C>T, and IVS3-48 T>C) in these patients. The family pedigree of patient A was then established by characterization of the genotype of the patient's relatives. We also analyzed the potential perniciousness of the missense mutation with bioinformatic software, Polyphen and Sift. In summary, Chinese EPP patients have similar manifestations to those of Caucasians, and identification of the Chinese FECH gene mutations expands the FECH genotypic spectrum and may contribute to genetic counseling. PMID- 27704753 TI - Screen-Printed Photochromic Textiles through New Inks Based on SiO2@naphthopyran Nanoparticles. AB - Photochromic silica nanoparticles (SiO2@NPT), fabricated through the covalent immobilization of silylated naphthopyrans (NPTs) based on 2H-naphtho[1,2-b]pyran (S1, S2) and 3H-naphtho[2,1-b]pyran (S3, S4) or through the direct adsorption of the parent naphthopyrans (1, 3) onto silica nanoparticles (SiO2 NPs), were successfully incorporated onto cotton fabrics by a screen-printing process. Two aqueous acrylic- (AC-) and polyurethane- (PU-) based inks were used as dispersing media. All textiles exhibited reversible photochromism under UV and solar irradiation, developing fast responses and intense coloration. The fabrics coated with SiO2@S1 and SiO2@S2 showed rapid color changes and high contrasts (DeltaE*ab = 39-52), despite presenting slower bleaching kinetics (2-3 h to fade to the original color), whereas the textiles coated with SiO2@S3 and SiO2@S4 exhibited excellent engagement between coloration and decoloration rates (coloration and fading times of 1 and 2 min, respectively; DeltaE*ab = 27-53). The PU-based fabrics showed excellent results during the washing fastness tests, whereas the AC-based textiles evidenced good results only when a protective transfer film was applied over the printed design. PMID- 27704754 TI - Visible and Near-Infrared Dual-Emission Carbogenic Small Molecular Complex with High RNA Selectivity and Renal Clearance for Nucleolus and Tumor Imaging. AB - Fluorescence imaging requires bioselective, sensitive, nontoxic molecular probes to detect the precise location of lesions for fundamental research and clinical applications. Typical inorganic semiconductor nanomaterials with large sizes (>10 nm) can offer high-quality fluorescence imaging due to their fascinating optical properties but are limited to low selectivity as well as slow clearance pathway. We here report an N- and O-rich carbogenic small molecular complex (SMC, MW < 1000 Da) that exhibits high quantum yield (up to 80%), nucleic acid-binding enhanced excitation-dependent fluorescence (EDF), and a near-infrared (NIR) emission peaked at 850 nm with an ultralarge Stokes shift (~500 nm). SMCs show strong rRNA affinity, and the resulting EDF enhancement allows multicolor visualization of nucleoli in cells for clear statistics. Furthermore, SMCs can be efficiently accumulated in tumor in vivo after injection into tumor-bearing mice. The NIR emission affords high signal/noise ratio imaging for delineating the true extent of tumor. Importantly, about 80% of injected SMCs can be rapidly excreted from the body in 24 h. No appreciable toxicological responses were observed up to 30 days by hematological, biochemical, and pathological examinations. SMCs have great potential as a promising nucleolus- and tumor-specific agent for medical diagnoses and biomedical research. PMID- 27704755 TI - Novel Composite PEM with Long-Range Ionic Nanochannels Induced by Carbon Nanotube/Graphene Oxide Nanoribbon Composites. AB - In the current study, carbon nanotube/graphene oxide nanoribbon (CNT/GONR) composites were obtained via a chemical "unzipping" method. Then novel CNT/GONR Nafion composite proton exchange membranes (PEMs) were prepared via a blending method. The CNT/GONR nanocomposites induce the adjustment of (-SO3-)n ionic clusters in Nafion matrix to construct long-range ionic nanochannels and keep the activity of ionic clusters at the same time. This dramatically promotes the proton transport of the CNT/GONR Nafion composite PEMs at low humidity and high temperature. The proton conductivity of the composite PEM with 0.5 wt % CNT/GONR is as high as 0.18 S.cm-1 at 120 degrees C and 40%RH, nine times of recast Nafion (0.02 S.cm-1) at the same conditions. The 1D/2D nanostructure of CNT/GONR nanocomposite also contributes to restrain the methanol permeability of CNT/GONR Nafion. The composite PEM shows a one-order-of-magnitude decrease (2.84 * 10-09 cm2.s-1) in methanol permeability at 40 degrees C. Therefore, incorporation of this 1D/2D nanocomposite into Nafion PEM is a feasible pathway to conquer the trade-off effect between proton conductivity and methanol resistance. PMID- 27704756 TI - Highly Modified Cellulose Nanocrystals and Formation of Epoxy-CNC Nanocomposites. AB - This work presents an environmentally friendly, iodine-catalysed chemical modification method to generate highly hydrophobic, optically active cellulose nanocrystals (CNC). The high degree of ester substitution (DS=2.18), hydrophobicity, crystalline behaviour and optical activity of the generated acetylated CNC (Ac-CNC) were quantified by TEM, FTIR, solid 13C NMR, contact angle, XRD and POM analyses. Ac-CNC possessing substantial enhancement in thermal stability (16.8%) and forms thin films with interlayer distance of 50-150 nm, presenting cavities suitable for entrapping nano and micro particles. Generated Ac-CNC proved as an effective reinforcing agent in hydrophobic polymer matrices for fabricating high performance nanocomposites. When integrated at a very low weight percentage (0.5%) in an epoxy matrix, Ac-CNC provided for a 73% increase in tensile strength and a 98% increase in modulus, demonstrating its remarkable reinforcing potential and effective stress transfer behaviour. The method of modification and the unique properties of the modified CNC (hydrophobicity, crystallinity, reinforcing ability and optical activity) render them a novel bionanomaterial for a range of multipurpose applications. PMID- 27704757 TI - Antibacterial and Anti-Inflammatory pH-Responsive Tannic Acid-Carboxylated Agarose Composite Hydrogels for Wound Healing. AB - pH-sensitive hydrogels play an important role in controlled drug release applications and have the potential to impact the management of wounds. In this study, we report the fabrication of novel carboxylated agarose/tannic acid hydrogel scaffolds cross-linked with zinc ions for the pH-controlled release of tannic acid. The resulting hydrogels exhibited negligible release of tannic acid at neutral and alkaline pH and sustained release at acidic pH, where they also displayed maximum swelling. The hydrogels also displayed favorable antibacterial and anti-inflammatory properties, and a lack of cytotoxicity toward 3T3 fibroblast cell lines. In simulated wound assays, significantly greater cell migration and proliferation was observed for cells exposed to tannic acid hydrogel extracts. In addition, the tannic acid hydrogels were able to suppress NO production in stimulated human macrophages in a concentration-dependent manner, indicating effective anti-inflammatory activity. Taken together, the cytocompatibility, antibacterial, and anti-inflammatory characteristics of these novel pH-sensitive hydrogels make them promising candidates for wound dressings. PMID- 27704758 TI - Additively Manufactured Macroporous Titanium with Silver-Releasing Micro /Nanoporous Surface for Multipurpose Infection Control and Bone Repair - A Proof of Concept. AB - Restoring large-scale bone defects, where osteogenesis is slow while infections lurk, with biomaterials represents a formidable challenge in orthopedic clinics. Here, we propose a scaffold-based multipurpose anti-infection and bone repairing strategy to meet such restorative needs. To do this, personalized multifunctional titanium meshes were produced through an advanced additive manufacturing process and dual "TiO2-poly(dopamine)/Ag (nano)" post modifications, yielding macroporous constructs with micro-/nanoporous walls and nanosilver bullets immobilized/embedded therein. Ultrahigh loading capacity and durable release of Ag+ were accomplished. The scaffolds were active against planktonic/adherent bacteria (Gram-negative and positive) for up to 12 weeks. Additionally, they not only defended themselves from biofilm colonization but also helped destroy existing biofilms, especially in combination with antibiotics. Further, the osteoblasts/bacteria coculture study displayed that the engineered surfaces aided MG-63 cells to combat bacterial invasion. Meanwhile, the scaffolds elicited generally acceptable biocompatibility (cell adhesion, proliferation, and viability) and hastened osteoblast differentiation and maturation (alkaline phosphatase production, matrix secretion, and calcification), by synergy of micro /nanoscale topological cues and bioactive catecholamine chemistry. Although done ex vivo, these studies reveal that our three-in-one strategy (infection prophylaxis, infection fighting, and bone repair) has great potential to simultaneously prevent/combat infections and bridge defected bone. This work provides new thoughts to the use of enabling technologies to design biomaterials that resolve unmet clinical needs. PMID- 27704759 TI - Thermally Conductive, Electrical Insulating, Optically Transparent Bi-Layer Nanopaper. AB - Cellulose nanofiber (CNF) from abundant and renewable wood is an emerging material with excellent mechanical, chemical, and optical properties. Transparent nanopaper made of CNF (CNF-nanopaper) could potentially replace plastics in electronics due to its excellent optical transparency, mechanical strength, and biodegradability. However, CNF-nanopaper normally has a low thermal conductivity and poor stability in increasing temperatures, which is not suitable for long term stability and reliability in devices. Herein, for the first time, we report a thermally conductive, electrically insulating, and optically transparent nanopaper using a bilayer design where a thin layer of boron nitride (BN) nanosheets were coated on the CNF-nanopaper. An optical transparency (70%) and a thermal conductivity (0.76 W/m/K) were successfully achieved through a solution based process at room temperature. Such an optically transparent, electrically insulating, and thermally conductive bilayer nanopaper can find applications in a range of electronic devices. PMID- 27704760 TI - Crack/Fold Hybrid Structure-Based Fluidic Networks Inspired by the Epidermis of Desert Lizards. AB - A bioinspired fluidic system with cracks and folds was introduced to emulate the structures and functions of desert lizards' integuments, which show marked ability of water management. Because there was a structural analogy between scales and interscalar channels of lizard's skin and cracks and folds of a bilayer elastic material, we can mimic lizard's skin by controlling the stress distribution on patterned elastomers. Our system showed not only capillary-driven water retention within confined fluidic network, but also stretching-driven biaxial water transport. Observed features of our system may enhance understanding of water management in relation to morphogenetic aspects of lizards. PMID- 27704761 TI - Analysis of Zinc Nitride Resistive Indicators under Different Relative Humidity Conditions. AB - Zinc nitride (Zn3N2) is a metastable material in ambient conditions because of its high reactivity with water molecules. In this work we perform a systematic analysis of the oxidation of Zn3N2 layers grown by RF magnetron sputtering at room temperature. The aging and transformation of the layers toward a ZnO film is explored by means of spectroscopic ellipsometry and scanning electron microscopy for conditions with different relative humidity (RH). Accurate depth profiling by means of elastic recoil detection analysis with a time-of-flight telescope demonstrated the substitutional reaction between O and N and the important effect of the RH in this process. Because of this metastability the resistivity of the layers changes several orders of magnitude. Taking advantage of this principle, we develop electronic indicators and characterize the transformation of their electrical properties as a function of the ambient RH, finding a good correlation between the transformation time and the RH level. PMID- 27704762 TI - Applications of Novel Carbon/AlPO4 Hybrid-Coated H2Ti12O25 as a High-Performance Anode for Cylindrical Hybrid Supercapacitors. AB - The hybrid supercapacitor using carbon/AlPO4 hybrid-coated H2Ti12O25/activated carbon is fabricated as a cylindrical cell and investigated against electrochemical performances. The hybrid coating shows that the conductivity for the electron and Li ion is superior and it prevented active material from HF attack. Consequently, carbon/AlPO4 hybrid-coated H2Ti12O25 shows enhanced rate capability and long-term cycle life. Also, the hybrid coating inhibits swelling phenomenon caused by gas generated as decomposition reaction of electrolyte. Therefore, the hybrid supercapacitor using carbon/AlPO4 hybrid-coated H2Ti12O25/activated carbon can be applied to an energy storage system that requires a long-term life. PMID- 27704764 TI - Synthesis and Adsorption Properties of Hierarchically Ordered Nanostructures Derived from Porous CaO Network. AB - Using the porous framework of CaO as templates and reagents, we explored a surfactant-free and economical method for preparing calcium silicate hydrate (CSH) hierarchically ordered nanostructures. Incorporation of SiO2 nanoparticles into the CaO framework, followed by a reaction assisted by hydrothermal treatment, resulted in the formation of CSH with well-defined morphologies. The structural features of CSH were characterized by 3-D hierarchical networks, wherein nanofibers assembled to form nanosheets, and nanosheets assembled to form hierarchically ordered structures. Investigation of the crystal growth mechanism indicated that the key to forming the CSH ordered assembly structure was confining the Ca/Si ratio within a small range. Nonclassic oriented aggregation mechanism was used to describe the crystal growth of nanosheets, while the porous CaO framework served as template/reagents responsible for the formation of hierarchical structures. The resulting CSH adsorbent exhibited better performance in removing Pb(II) compared with other types of random CSH adsorbents. Additionally, the hierarchical structure of CSH provided more pores and active sites as support for other active functional materials such as zerovalent iron (Fe0). As-produced CSH@Fe nanocomposite with self-supported structures displayed high capacities for removal of Pb(II) after five adsorption-desorption cycles, and high capacities for other heavy metal ions (Cu2+, Cd2+, and Cr2O72-) and organic contaminants. PMID- 27704763 TI - Impact of Fullerene Mixing Behavior on the Microstructure, Photophysics, and Device Performance of Polymer/Fullerene Solar Cells. AB - Here, a comprehensive study of the influence of polymer:fullerene mixing behavior on the performance, thin-film microstructure, photophysics, and device physics of polymer solar cells is presented. In particular, blends of the donor polymer PBDTTT-EFT with the acceptor PC71BM that exhibit power conversion efficiencies over 9% are investigated. Through tuning of the fullerene concentration in PBDTTT EFT:PC71BM blends, the impact of fullerene mixing behavior is systematically investigated via a combination of synchrotron-based X-ray scattering and spectroscopy techniques. The impact of fullerene loading on photophysics and device physics is further explored with steady-state photoluminescence measurements, ultrafast transient absorption spectroscopy, and transient photovoltage measurements. In the low fullerene concentration regime (<50 wt %), most fullerene molecules are dispersed in the polymer matrix, resulting in severe geminate and nongeminate recombination due to a lack of pure fullerene aggregates and percolating pathways for charge separation and transport. In the high fullerene concentration regime (>70 wt %), large fullerene domains result in incomplete PC71BM exciton harvesting with the presence of fullerene molecules also disrupting the molecular packing of polymer crystallites. The optimum fullerene concentration of ~60-67 wt % balances the requirements of charge generation and charge collection. These findings demonstrate that controlling the fullerene concentration in the mixed phase and optimizing the balance between pure and mixed phases are critical for maximizing the efficiency of highly mixed polymer/fullerene solar cells.

AB - Chemically exfoliated MoS2 (ce-MoS2) has emerged in recent years as an attractive two-dimensional material for use in relevant technological applications, but fully exploiting its potential and versatility will most probably require the deployment of appropriate chemical modification strategies. Here, we demonstrate that extensive covalent functionalization of ce-MoS2 nanosheets with acetic acid groups (~0.4 groups grafted per MoS2 unit) based on the organoiodide chemistry brings a number of benefits in terms of their processability and functionality. Specifically, the acetic acid-functionalized nanosheets were furnished with long term (>6 months) colloidal stability in aqueous medium at relatively high concentrations, exhibited a markedly improved temporal retention of catalytic activity toward the reduction of nitroarenes, and could be more effectively coupled with silver nanoparticles to form hybrid nanostructures. Furthermore, in vitro cell proliferation tests carried out with murine fibroblasts suggested that the chemical derivatization had a positive effect on the biocompatibility of ce MoS2. A hydrothermal annealing procedure was also implemented to promote the structural conversion of the functionalized nanosheets from the 1T phase that was induced during the chemical exfoliation step to the original 2H phase of the starting bulk material, while retaining at the same time the aqueous colloidal stability afforded by the presence of the acetic acid groups. Overall, by highlighting the benefits of this type of chemical derivatization, the present work should contribute to strengthen the position of ce-MoS2 as a two-dimensional material of significant practical utility.

AB - The supramolecular approach plays a pivotal role in the construction of smart and functional materials due to the reversible nature of noncovalent interactions. In the present work, two compounds, cholesterol-functionalized calix[4]pyrrole (CCP) and perylene bisimide diacid (PDA), were synthesized. Little fluorescence is observed in the ethanol solution of the mixture of CCP and PDA, while the solution turns fluorescent upon introduction of ammonia, which is attributed to the formation of a supramolecular ensemble, PDA/(CCP)2/NH3. The fluorescence emission of the as-formed ensemble is sensitive to the presence of phenol, an electron-rich analyte. Interestingly, the sensing can also be observed in the film state, and the relevant detection limit (DL) is lower than 1 ppb. Moreover, the sensing could also be performed in a visualized manner. Upon the basis of the findings, a sensor device with instant response and good reversibility was developed. Further studies revealed that the as-developed fluorescent ensemble is also sensitive to the presence of TNT, an electron-poor compound. The DL for this sensing is ~80 nM. To our knowledge, this is the first report that a fluorescent sensor could be used for phenol sensing in the vapor state, and for sensing of both electron-rich and electron-poor analytes in solution state. It is believed that the present study presents a distinctive example that demonstrates how smart sensing is realized via combination of the host-guest chemistry of calix[4]pyrrole and the aggregation and disaggregation property of PBI derivatives.

AB - Antigen recognition followed by the activation of cytotoxic T-cells (CTLs) is a key step in adaptive immunity, resulting in clearance of viruses and cancers. The repertoire of peptides that have the ability to bind to the major histocompatibility type-I (MHC-I) is enormous, but the approaches available for studying the diversity of the peptide repertoire on a cell are limited. Here, we explore the use of bioorthogonal chemistry to quantify specific peptide-MHC-I complexes (pMHC-I) on cells. We show that modifying epitope peptides with bioorthogonal groups in surface accessible positions allows wild-type-like MHC-I binding and bioorthogonal ligation using fluorogenic chromophores in combination with a Cu(I)-catalyzed Huisgen cycloaddition reaction. We expect that this approach will make a powerful addition to the antigen presentation toolkit as for the first time it allows quantification of antigenic peptides for which no detection tools exist. PMID- 27704769 TI - Mechanically Tunable, Readily Processable Ion Gels by Self-Assembly of Block Copolymers in Ionic Liquids. AB - Room temperature ionic liquids are of great interest for many advanced applications, due to the combination of attractive physical properties with essentially unlimited tunability of chemical structure. High chemical and thermal stability, favorable ionic conductivity, and complete nonvolatility are just some of the most important physical characteristics that make ionic liquids promising candidates for emerging technologies. Examples include separation membranes, actuators, polymer gel electrolytes, supercapacitors, ion batteries, fuel cell membranes, sensors, printable plastic electronics, and flexible displays. However, in these and other applications, it is essential to solidify the ionic liquid, while retaining the liquid state properties of interest. A broadly applicable solidification strategy relies on gelation by addition of suitable triblock copolymers with the ABA architecture, producing ion gels or ionogels. In this paradigm, the A end blocks are immiscible with the ionic liquid, and consequently self-assemble into micellar cores, while some fraction of the well solvated B midblocks bridge between micelles, forming a percolating network. The chemical structures of the A and B repeat units, the molar mass of the blocks, and the concentration of the copolymer in the ionic liquid are all independently tunable to attain desired property combinations. In particular, the modulus of the resulting ion gel can be readily varied between 100 Pa and 1 MPa, with little sacrifice of the transport properties of the ionic liquid, such as ionic conductivity or gas diffusivity. Suitable A blocks can impart thermoreversible gelation (with solidification either on heating or cooling) or even photoreversible gelation. By virtue of the nonvolatility of ionic liquids, a wide range of processing strategies can be employed directly to prepare ion gels in thin or thick film forms, including solvent casting, spin coating, aerosol jet printing, photopatterning, and transfer printing. For higher modulus ion gels it is even possible to employ a manual "cut and stick" strategy for easy device fabrication. Ion gels prepared from common triblock copolymers, for example, with A = polystyrene and B = poly(ethylene oxide) or poly(methyl methacrylate), in imidazolium based ionic liquids provide exceptional performance in membranes for separating CO2 from N2 or CH4. The same materials also are the best available gate dielectrics for printed plastic electronics, because their high capacitance endows organic transistors with milliamp output currents for sub-1 V applied bias, with switching speeds that can go well beyond 100 kHz, while being amenable to large area roll-to-roll printing. Incorporation of well-designed electroluminescent (e.g., Ru(bpy)3-based) or electrochromic (e.g., viologen based) moieties into ion gels held between transparent electrodes yields flexible color displays operating with sub-1 V dc inputs. PMID- 27704767 TI - Boc3Arg-Linked Ligands Induce Degradation by Localizing Target Proteins to the 20S Proteasome. AB - Targeted protein degradation is a promising strategy for drug design and functional assessment. Several small molecule approaches have been developed that localize target proteins to ubiquitin ligases, inducing ubiquitination and subsequent degradation by the 26S proteasome. We discovered that the degradation of a target protein can also be induced by a recognition ligand linked to tert butyl carbamate (Boc3)-protected arginine (B3A). Here, we show that this process requires the proteasome but does not involve ubiquitination of the target protein. B3A does not perturb the structure of the target protein; instead, a B3A ligand stabilizes its target protein. B3A ligands stimulate activity of purified 20S proteasome, demonstrating that the tag binds directly to the 20S proteasome. Moreover, purified 20S proteasome is sufficient to degrade target proteins in the presence of their respective B3A-linked recognition ligands. These observations suggest a simple model for B3A-mediated degradation wherein the B3A tag localizes target proteins directly to the 20S proteasome. Thus, B3A ligands are the first example of a ubiquitin-free strategy for targeted protein degradation. PMID- 27704770 TI - Spontaneous Uphill Movement and Self-Removal of Condensates on Hierarchical Tower Like Arrays. AB - Fast removal of condensates from surfaces is of great significance due to the enhancing thermal transfer coefficient and continuous condensation. But the losing super-hydrophobicity of lotus leaves questions us what kind of surface morphologies meets the self-removal of condensates? The uphill movement of condensates in textured surfaces is vital to avoiding flood and facilitating self removal. Here, super-hydrophobic micro-tower arrays were designed to explore the spontaneous uphill movement and Wenzel to Cassie transition as well as the self removal of condensates. The tower-like arrays enable spontaneous uphill movement of tiny condensates entrapped in microstructures due to the large upward Laplace pressure which is ~30 times larger than that on cone-like arrays. The sharp tips decrease the adhesion to suspending droplets and promote their fast self-removal. These results are important for designing desirable textured surfaces by enlarging upward Laplace pressure to facilitate condensates self-removal, which are widely applied in self-cleaning, anti-fogging, anti-icing, water harvesting and thermal management systems. PMID- 27704771 TI - Distinguishing between Leucine and Isoleucine by Integrated LC-MS Analysis Using an Orbitrap Fusion Mass Spectrometer. AB - Despite the great success of mass spectrometry (MS) for de novo protein sequencing, Leu and Ile have been generally considered to be indistinguishable by MS because their molecular masses are exactly the same. Positioning of incorrect Leu/Ile residues in variable domains, especially in CDRs (complementarity determining regions) of an antibody, may result in substantial loss of antigen binding affinity and specificity of the antibody. Here, we describe an integrated LC-MS based strategy, encompassing a combination of HCD (high-energy collisional dissociation) multistage mass spectrometric analysis (HCD-MSn) and ETD (electron transfer dissociation)-HCD MS3 analysis using an Orbitrap Fusion mass spectrometer, to reliably identify Leu and Ile residues in proteins and peptides. The merits and limitations of this Leu/Ile discrimination approach are evaluated. Using the new approach, along with proposed decision-making guidelines we unambiguously identified every Leu/Ile residue in peptides containing up to five Leu/Ile residues and molecular masses up to 3000 Da. In addition, we have demonstrated, for the first time, that every Leu/Ile residue in the variable regions of a monoclonal antibody that could not be assigned by antibody germline sequence alignment could be correctly determined using this approach. Our results suggest that, by incorporating this approach into existing de novo antibody sequencing protocols, 100% of antibody amino acid sequences, including identity of Leu and Ile residues, can be accurately obtained solely by means of mass spectrometry. In principle, this integrated, online LC-MS approach for Leu/Ile assignment can be applied to de novo sequencing of any protein or peptide. PMID- 27704773 TI - Controlling the Polarization State of Light with Plasmonic Metal Oxide Metasurface. AB - Conventional plasmonic materials, namely noble metals, hamper the realization of practical plasmonic devices due to their intrinsic limitations, such as lack of capabilities to tune in real-time their optical properties, failure to assimilate with CMOS-standards, and severe degradation at elevated temperatures. Transparent conducting oxides (TCOs) is a promising alternative as plasmonic material throughout the near- and mid-infrared wavelengths. In addition to compatibility with established silicon-based fabrication procedures, TCOs provide great flexibility in the design and optimization of plasmonic devices since their intrinsic optical properties can be tailored and dynamically tuned. In this work, we experimentally demonstrate metal-oxide metasurfaces operating as quarter-wave plates (QWP) over a broad near infrared (NIR) range from 1.75 to 2.50 um. We employ zinc oxide highly doped with gallium (Ga:ZnO) as the plasmonic constituent material of the metasurfaces, and fabricate arrays of orthogonal nanorod pairs. Our Ga:ZnO metasurfaces provide a high degree of circular polarization across a broad range of two distinct optical bands in the NIR. Flexible broadband tunability of the QWP metasurfaces is achieved by the significant shifts of their optical bands, and without any degradation in their performance, after a post annealing process up to 450 degrees C. PMID- 27704772 TI - Zika Virus: Emergence, Phylogenetics, Challenges, and Opportunities. AB - Zika virus (ZIKV) is an emerging arthropod-borne pathogen that has recently gained notoriety due to its rapid and ongoing geographic expansion and its novel association with neurological complications. Reports of ZIKV-associated Guillain Barre syndrome as well as fetal microcephaly place emphasis on the need to develop preventative measures and therapeutics to combat ZIKV infection. Thus, it is imperative that models to study ZIKV replication and pathogenesis and the immune response are developed in conjunction with integrated vector control strategies to mount an efficient response to the pandemic. This paper summarizes the current state of knowledge on ZIKV, including the clinical features, phylogenetic analyses, pathogenesis, and the immune response to infection. Potential challenges in developing diagnostic tools, treatment, and prevention strategies are also discussed. PMID- 27704774 TI - Characterization of Few-Layer 1T' MoTe2 by Polarization-Resolved Second Harmonic Generation and Raman Scattering. AB - We study the crystal symmetry of few-layer 1T' MoTe2 using the polarization dependence of the second harmonic generation (SHG) and Raman scattering. Bulk 1T' MoTe2 is known to be inversion symmetric; however, we find that the inversion symmetry is broken for finite crystals with even numbers of layers, resulting in strong SHG comparable to other transition metal dichalcogenides. Group theory analysis of the polarization dependence of the Raman signals allows for the definitive assignment of all the Raman modes in 1T' MoTe2 and clears up a discrepancy in the literature. The Raman results were also compared with density functional theory simulations and are in excellent agreement in the layer depenent variations of the Raman modes. The experimental measurements also determine the relationship between the crystal axes and the polarization dependence of the SHG and Raman scattering, which now allows the anisotropy of polarized SHG or Raman signal to independently determine the crystal orientation. PMID- 27704776 TI - Controllable Laser Reduction of Graphene Oxide Films for Photoelectronic Applications. AB - This article presents a new simple method of creating light-absorbing carbon material for optical devices such as bolometers. A simple method of laser microstructuring of graphene oxide is used in order to create such material. The absorption values of more than 98% in the visible and more than 90% in the infrared range are achieved. Moreover thermal properties of the films, such as temperature dependence and the thermal response of the samples, are studied. The change in resistance with temperature is 13 Ohm K-1, temperature coefficient of resistance (TCR) is 0.3% K-1, and the sensitivity is 0.17 V W-1 at 300 K. Thermal conductivity is rather high at ~104 W m-1 K-1 at 300 K. The designed bolometer operates at room temperature using incandescent lamp as a light source. This technique suggests a new inexpensive way to create a selective absorption coating and/or active layer for optical devices. Developed GO and rGO films have a large surface area and high conductivity. These properties make carbon coatings a perfect candidate for creating a new type of optoelectronic devices (gas sensors, detectors of biological objects, etc.). PMID- 27704775 TI - Rational Design of Dual Agonist-Antibody Fusions as Long-acting Therapeutic Hormones. AB - Recent studies have suggested that modulation of two or more signaling pathways can achieve substantial weight loss and glycemic stability. We have developed an approach to the generation of bifunctional antibody agonists that activate leptin receptor and GLP-1 receptor. Leptin was fused into the complementarity determining region 3 loop of the light chain alone, or in combination with exendin-4 (EX4) fused at the N-terminus of the heavy chain of Herceptin. The antibody fusions exhibit similar or increased in vitro activities on their cognate receptors, but 50-100-fold longer circulating half-lives in rodents compared to the corresponding native peptides/proteins. The efficacy of the leptin/EX4 dual antibody fusion on weight loss, especially fat mass loss, was enhanced in ob/ob mice and DIO mice compared to the antibody fusion of either EX4 or leptin alone. This work demonstrates the versatility of this combinatorial fusion strategy for generating dual antibody agonists with long half-lives. PMID- 27704777 TI - Nanoscale-Barrier Formation Induced by Low-Dose Electron-Beam Exposure in Ultrathin MoS2 Transistors. AB - Utilizing an innovative combination of scanning-probe and spectroscopic techniques, supported by first-principles calculations, we demonstrate how electron-beam exposure of field-effect transistors, implemented from ultrathin molybdenum disulfide (MoS2), may cause nanoscale structural modifications that in turn significantly modify the electrical operation of these devices. Quite surprisingly, these modifications are induced by even the relatively low electron doses used in conventional electron-beam lithography, which are found to induce compressive strain in the atomically thin MoS2. Likely arising from sulfur vacancy formation in the exposed regions, the strain gives rise to a local widening of the MoS2 bandgap, an idea that is supported both by our experiment and by the results of first-principles calculations. A nanoscale potential barrier develops at the boundary between exposed and unexposed regions and may cause extrinsic variations in the resulting electrical characteristics exhibited by the transistor. The widespread use of electron-beam lithography in nanofabrication implies that the presence of such strain must be carefully considered when seeking to harness the potential of atomically thin transistors. At the same time, this work also promises the possibility of exploiting the strain as a means to achieve "bandstructure engineering" in such devices. PMID- 27704778 TI - Functional Packaging of Lateral Flow Strip Allows Simple Delivery of Multiple Reagents for Multistep Assays. AB - This paper presents a rotary device designed for facile delivery of multiple reagents to a paper strip for multistep assays. Its purpose is to allow users to easily perform multistep assays and achieve sensitive detection. While the test strip remains stationary, rotating the top piece of the device aligns the reagent and absorbent pads to each end of the paper strip and initiates fluid flow. Further incremental rotation makes an adjacent pair of pads to align simultaneously, causing fluid flow of subsequent reagent that was preloaded in the reagent pad. In this work, various porous substrates were tested to observe their effect on overall flow rate of the system and multistep assays were performed to demonstrate its simple use. As a proof of concept, enzyme-linked immunosorbent assay was carried out to detect Escherichia coli O157:H7. PMID- 27704779 TI - Long-Term Stability and Reliability of Black Phosphorus Field-Effect Transistors. AB - Black phosphorus has been recently suggested as a very promising material for the use in 2D field-effect transistors. However, due to its poor stability under ambient conditions, this material has not yet received as much attention as for instance MoS2. We show that the recently demonstrated Al2O3 encapsulation leads to highly stable devices. In particular, we report our long-term study on highly stable black phosphorus field-effect transistors which show stable device characteristics for at least eight months. This high stability allows us to perform a detailed analysis of their reliability with respect to hysteresis as well as the arguably most important reliability issue in Silicon technologies, the bias-temperature instability. We find that the hysteresis in these transistors depends strongly on the sweep rate and temperature. Moreover, the hysteresis dynamics in our devices are reproducible over a long time, which underlines their high reliability. Also, by using detailed physical models for oxide traps developed for Si technologies, we are able to capture the channel electrostatics of the black phosphorus FETs and determine the position of the defect energy band. Finally, we demonstrate that both hysteresis and bias temperature instabilities are due to thermally activated charge trapping/detrapping by oxide traps and can be reduced if the device is covered by Teflon-AF. PMID- 27704780 TI - Nanoparticle-Based Magnetoelectric BaTiO3-CoFe2O4 Thin Film Heterostructures for Voltage Control of Magnetism. AB - Multiferroic composite materials combining ferroelectric and ferromagnetic order at room temperature have great potential for emerging applications such as four state memories, magnetoelectric sensors, and microwave devices. In this paper, we report an effective and facile liquid phase deposition route to create multiferroic composite thin films involving the spin-coating of nanoparticle dispersions of BaTiO3, a well-known ferroelectric, and CoFe2O4, a highly magnetostrictive material. This approach offers great flexibility in terms of accessible film configurations (co-dispersed as well as layered films), thicknesses (from 100 nm to several MUm) and composition (5-50 wt % CoFe2O4 with respect to BaTiO3) to address various potential applications. A detailed structural characterization proves that BaTiO3 and CoFe2O4 remain phase-separated with clear interfaces on the nanoscale after heat treatment, while electrical and magnetic studies indicate the simultaneous presence of both ferroelectric and ferromagnetic order. Furthermore, coupling between these orders within the films is demonstrated with voltage control of the magnetism at ambient temperatures. PMID- 27704781 TI - Microscale Measurement and Visualization of Sulfide delta34S Using Photographic Film Sulfide Capture Coupled with Laser Ablation Multicollector Inductively Coupled Plasma Mass Spectrometry. AB - Measurements of the isotopic composition of sulfate and sulfide have been essential to uncovering the microbial and geochemical processes that drive Earth's sulfur cycle. These processes routinely operate over submillimeter spatial scales in anaerobic environments, necessitating sulfur isotopic measurement techniques that can identify isotopic variability over equivalently small scales. Here we present a new method for small-scale (102 MUm) measurements of delta34S using black and white photographic film sulfide capture coupled with delta34S determination using laser ablation multicollector inductively coupled plasma mass spectrometry. We find that the method enables measurement of delta34S for aqueous sulfide in natural waters at high spatial resolution (<1 mm2) with reasonable accuracy (<0.90/00, 2sigma) and external precision (<0.80/00, 2sigma), and across an environmentally relevant concentration range (0.01-20 mmol L-1). A concentration-dependent correction is required during data analysis to achieve these specifications, which corrects delta34S measurements for mixing with sulfur native to the film material and fractionation due to Ag2S precipitation from aqueous sulfide. We demonstrate the applicability of our technique using an anaerobic incubation of seawater and sediment, mapping two-dimensional delta34Ssulfide at a 535 MUm * 535 MUm spatial scale, with internal precisions of 1.40/00 to 1.50/00. Our method offers the benefits of minimal sample preparation and common availability of sampling material (black and white photographic film), while retaining the necessary precision to identify sulfide delta34S variability and isotopic fractionations at high ambient sulfate and with high spatial resolutions in sulfidic environments. PMID- 27704783 TI - Single-Atom Switches and Single-Atom Gaps Using Stretched Metal Nanowires. AB - Utilizing individual atoms or molecules as functional units in electronic circuits meets the increasing technical demands for the miniaturization of traditional semiconductor devices. To be of technological interest, these functional devices should be high-yield, consume low amounts of energy, and operate at room temperature. In this study, we developed nanodevice called quantized conductance atomic switches (QCAS) that satisfies these requirements. The QCAS operates by applying a feedback-controlled voltage to a nano constriction within a stretched nanowire. We demonstrated that individual metal atoms could be removed from the nano-constriction and that the removed metal atoms could be refilled into the nano-constriction, thus yielding a reversible quantized conductance switch. We determined the key parameters for the QCAS between the 'on' and 'off' states at room temperature under a small operating voltage. By controlling the applied bias voltage, the atoms can be further completely removed from the constriction to break the nanowire, generating single atom nanogaps. These atomic nanogaps are quite stable under a sweeping voltage and can be re-adjusted with sub-angstrom accuracy, thus fulfilling the requirement of both reliability and flexibility for the high-yield fabrication of molecular devices.

AB - Reaction of [Au2Ag2R4(Et2O)2] (R = C6Cl2F3- or C6F5-) with [Pb{HB(pz)3}]Cl in a 1:2 molar ratio led to complexes [AuPb{HB(pz)3}R2] (R = C6Cl2F3- (2) or C6F5- (3)) through transmetalation reactions. The crystal structures of these complexes display unsupported Au(I)...Pb(II) interactions of 3.0954(4) (2) and 3.2778(4) (3) A, together with one (2) or two (3) F...Pb weak contacts. These intermetallic distances are compared to the shortest one found for the previously reported complex [Pb{HB(pz)3}Au(C6Cl5)2] (1) of 3.0494(4) (1) A, showing a clear dependence with the donating properties of the different aurate units. The complexes are emissive in the solid state due to charge transfer transitions associated with the presence of Au(I)...Pb(II) interactions, in which the intermetallic distance plays a crucial role. Density functional theory and time dependent density functional theory calculations support the assignment of the luminescent properties of the complexes. Ab initio Hartree-Fock and MP2 calculations on model systems of complexes 2 and 3 show the presence of strong Au(I)...Pb(II) closed-shell interactions of an ionic plus dispersive nature together with weak F...Pb contacts of a dispersive origin in the case of complexes 2 and 3. PMID- 27704782 TI - Essential but Not Vulnerable: Indazole Sulfonamides Targeting Inosine Monophosphate Dehydrogenase as Potential Leads against Mycobacterium tuberculosis. AB - A potent, noncytotoxic indazole sulfonamide was identified by high-throughput screening of >100,000 synthetic compounds for activity against Mycobacterium tuberculosis (Mtb). This noncytotoxic compound did not directly inhibit cell wall biogenesis but triggered a slow lysis of Mtb cells as measured by release of intracellular green fluorescent protein (GFP). Isolation of resistant mutants followed by whole-genome sequencing showed an unusual gene amplification of a 40 gene region spanning from Rv3371 to Rv3411c and in one case a potential promoter mutation upstream of guaB2 (Rv3411c) encoding inosine monophosphate dehydrogenase (IMPDH). Subsequent biochemical validation confirmed direct inhibition of IMPDH by an uncompetitive mode of inhibition, and growth inhibition could be rescued by supplementation with guanine, a bypass mechanism for the IMPDH pathway. Beads containing immobilized indazole sulfonamides specifically interacted with IMPDH in cell lysates. X-ray crystallography of the IMPDH-IMP-inhibitor complex revealed that the primary interactions of these compounds with IMPDH were direct pi-pi interactions with the IMP substrate. Advanced lead compounds in this series with acceptable pharmacokinetic properties failed to show efficacy in acute or chronic murine models of tuberculosis (TB). Time-kill experiments in vitro suggest that sustained exposure to drug concentrations above the minimum inhibitory concentration (MIC) for 24 h were required for a cidal effect, levels that have been difficult to achieve in vivo. Direct measurement of guanine levels in resected lung tissue from tuberculosis-infected animals and patients revealed 0.5-2 mM concentrations in caseum and normal lung tissue. The high lesional levels of guanine and the slow lytic, growth-rate-dependent effect of IMPDH inhibition pose challenges to developing drugs against this target for use in treating TB.

Transparent and conductive doped metal oxides are widely used in industry due to their excellent optoelectronic properties as well as the mature understanding of their production and handling. However, they are not compatible with future flexible electronics developments where large-scale production will likely involve roll-to-roll manufacturing. Recent studies have shown that carbon nanotubes provide unique chemical, physical, and optoelectronic properties, making them an important alternative to doped metal oxides. This Review provides a comprehensive analysis of carbon nanotube transparent conductive films covering detailed fabrication methods including patterning of the films, chemical doping effects, and hybridization with other materials. There is a focus on optoelectronic properties of the films and potential in applications such as photovoltaics, touch panels, liquid crystal displays, and organic light-emitting diodes in conjunction with a critical analysis of both the merits and shortcomings of carbon nanotube transparent conductive films.

AB - The mechanical properties and biocompatibility of spider silks have made them one of the most sought after and studied natural biomaterials. A biomimetic process has been developed that uses water to solvate purified recombinant spider silk proteins (rSSps) prior to material formation. The absence of harsh organic solvents increases cost effectiveness, safety, and decreases the environmental impact of these materials. This development allows for the investigation of aqueous-based rSSps as coatings and adhesives and their potential applications. In these studies it was determined that fiber-based rSSps in nonfiber formations have the capability to coat and adhere numerous substrates, whether rough, smooth, hydrophobic, or hydrophilic. Further, these materials can be functionalized for a variety of processes. Drug-eluting coatings have been made with the capacity to release a variety of compounds in addition to their inherent ability to prevent blood clotting and biofouling. Additionally, spider silk protein adhesives are strong enough to outperform some conventional glues and still display favorable tissue implantation properties. The physical properties, corresponding capabilities, and potential applications of these nonfibrous materials were characterized in this study. Mechanical properties, ease of manufacturing, biodegradability, biocompatibility, and functionality are the hallmarks of these revolutionary spider silk protein materials.

AB - Corrosion-protective coatings for silicate glass based on the transfer of one or two layers of graphene grown on copper by chemical vapor deposition have been demonstrated. The effectiveness of graphene to act as a glass corrosion inhibitor was evaluated by water immersion testing. After 120 days of immersion in water, bare glass samples had a significant increase in surface roughness and defects, which resulted in a marked reduction in fracture strength. In contrast, the single- and double-layer graphene-coated glasses experienced negligible changes in both fracture strength and surface roughness. The anticorrosion mechanism was also studied.

AB - Fully chlorinated carborate and dodecaborate cages such as [CHB11Cl11]- and [Me3NB12Cl11]- are prominent examples of valuable and chemically rather inert weakly coordinating anions. While both anions can be obtained by chlorination of the precursors [CH12B11]- and [H3NB12H11]- with SO2Cl2 followed by methylation for the synthesis of [Me3NB12Cl11]-, best results were found using photochemical chlorination with SO2Cl2 for [CH12B11]- and thermal chlorination with SO2Cl2 for [H3NB12H11]-. The hexachlorinated anion [n-Pr3NB12H5Cl6]- was formed readily within 30 min by chlorination of [n-Pr3NB12H11]-, but attempts to synthesize isopropyl-substituted ammonio-dodecaborates with a higher chlorination number resulted in the formation of mixtures and partial decomposition. The silver and trityl salts of the anions [CHB11Cl11]-, [Me3NB12Cl11]-, and [n-Pr3NB12H5Cl6]- as well as the contact ion-pair [Et2Al][Me3NB12Cl11] were also prepared, and the compounds [Ag(NCMe)][Me3NB12Cl11], [Et2Al][Me3NB12Cl11], and [Et4N][i Pr3NB12H5Cl6] were also characterized by X-ray crystallography.

PMID- 27704791 TI - Herbivory by an Outbreaking Moth Increases Emissions of Biogenic Volatiles and Leads to Enhanced Secondary Organic Aerosol Formation Capacity. AB - In addition to climate warming, greater herbivore pressure is anticipated to enhance the emissions of climate-relevant biogenic volatile organic compounds (VOCs) from boreal and subarctic forests and promote the formation of secondary aerosols (SOA) in the atmosphere. We evaluated the effects of Epirrita autumnata, an outbreaking geometrid moth, feeding and larval density on herbivore-induced VOC emissions from mountain birch in laboratory experiments and assessed the impact of these emissions on SOA formation via ozonolysis in chamber experiments. The results show that herbivore-induced VOC emissions were strongly dependent on larval density. Compared to controls without larval feeding, clear new particle formation by nucleation in the reaction chamber was observed, and the SOA mass loadings in the insect-infested samples were significantly higher (up to 150 fold). To our knowledge, this study provides the first controlled documentation of SOA formation from direct VOC emission of deciduous trees damaged by known defoliating herbivores and suggests that chewing damage on mountain birch foliage could significantly increase reactive VOC emissions that can importantly contribute to SOA formation in subarctic forests. Additional feeding experiments on related silver birch confirmed the SOA results. Thus, herbivory-driven volatiles are likely to play a major role in future biosphere-vegetation feedbacks such as sun-screening under daily 24 h sunshine in the subarctic.

AB - Increasing concentrations of dissolved silicate progressively retard Fe(II) oxidation kinetics in the circum-neutral pH range 6.0-7.0. As Si:Fe molar ratios increase from 0 to 2, the primary Fe(III) oxidation product transitions from lepidocrocite to a ferrihydrite/silica-ferrihydrite composite. Empirical results, supported by chemical kinetic modeling, indicated that the decreased heterogeneous oxidation rate was not due to differences in absolute Fe(II) sorption between the two solids types or competition for adsorption sites in the presence of silicate. Rather, competitive desorption experiments suggest Fe(II) was associated with more weakly bound, outer-sphere complexes on silica ferrihydrite compared to lepidocrocite. A reduction in extent of inner-sphere Fe(II) complexation on silica-ferrihydrite confers a decreased ability for Fe(II) to undergo surface-induced hydrolysis via electronic configuration alterations, thereby inhibiting the heterogeneous Fe(II) oxidation mechanism. Water samples from a legacy radioactive waste site (Little Forest, Australia) were shown to exhibit a similar pattern of Fe(II) oxidation retardation derived from elevated silicate concentrations. These findings have important implications for contaminant migration at this site as well as a variety of other groundwater/high silicate containing natural and engineered sites that might undergo iron redox fluctuations. PMID- 27704794 TI - Influence of Ligand Architecture in Tuning Reaction Bifurcation Pathways for Chlorite Oxidation by Non-Heme Iron Complexes. AB - Reaction bifurcation processes are often encountered in the oxidation of substrates by enzymes and generally lead to a mixture of products. One particular bifurcation process that is common in biology relates to electron transfer versus oxygen atom transfer by high-valent iron(IV)-oxo complexes, which nature uses for the oxidation of metabolites and drugs. In biomimicry and bioremediation, an important reaction relates to the detoxification of ClOx- in water, which can lead to a mixture of products through bifurcated reactions. Herein we report the first three water-soluble non-heme iron(II) complexes that can generate chlorine dioxide from chlorite at ambient temperature and physiological pH. These complexes are highly active oxygenation oxidants and convert ClO2- into either ClO2 or ClO3- via high-valent iron(IV)-oxo intermediates. We characterize the short-lived iron(IV)-oxo species and establish rate constants for the bifurcation mechanism leading to ClO2 and ClO3- products. We show that the ligand architecture of the metal center plays a dominant role by lowering the reduction potential of the metal center. Our experiments are supported by computational modeling, and a predictive valence bond model highlights the various factors relating to the substrate and oxidant that determine the bifurcation pathway and explains the origins of the product distributions. Our combined kinetic, spectroscopic, and computational studies reveal the key components necessary for the future development of efficient chlorite oxidation catalysts.

AB - A family of DyX4M(12-MCMnIII(N)shi-4) compounds were synthesized and magnetically characterized (X = salicylate, acetate, benzoate, trimethylacetate, M = NaI or KI). The bridging ligands were systematically varied while keeping the remainder of the MC-geometry constant. The type of monovalent cation, necessary for charge balance, was also altered. The dc magnetization and susceptibility of all compounds were similar across the series. Regardless of the identity of the countercation, the Dy(Hsal)4M 12-MC-4 compounds were the only compounds to show frequency-dependent ac magnetic susceptibility, a hallmark of single-molecule magnetism. This indicates that the nature of the bridging ligand in the 12 MCMnIII(N)shi-4 compounds strongly affects the out-of-phase magnetic properties. The SMM behavior appears to correlate with the pKa of the bridging ligand. PMID- 27704796 TI - Whole-Organism Transcriptomic Analysis Provides Mechanistic Insight into the Acute Toxicity of Emamectin Benzoate in Daphnia magna. AB - Emamectin benzoate (EMB) is an antisea lice chemical widely used in the aquaculture that may also unintentionally affect nontarget crustaceans in the environment. Although the adverse effects of this compound are well documented in various species, the full modes of action (MoAs) are still not well characterized. The current study was therefore conducted to characterize the MoAs of EMB and link perturbations of key toxicological pathways to adverse effects in the model freshwater crustacean Daphnia magna. Effects on molting and survival were determined after 48 h exposure to EMB, whereas global transcriptional changes and the ecdysone receptor (EcR) binding potency was determined to characterize the MoA. The results showed that the molting frequency and survival of D. magna decreased in a concentration-dependent manner, and the observed changes could not be attributed to direct interactions with the EcR. Major MoAs such as activation of glutamate-gated chloride channels and gamma-aminobutyric acid signaling, disruption of neuroendocrine regulation of molting, perturbation of energy homeostasis, suppression of DNA repair and induction of programmed cell death were observed by transcriptional analysis and successfully linked to the adverse effects. This study has demonstrated that acute exposure to intermediate and high pM levels of EMB may pose hazards to nontarget crustaceans in the aquatic environment. PMID- 27704797 TI - Phosphorus(V) Porphyrin-Based Molecular Turnstiles. AB - A new cationic molecular turnstile based on a P(V) porphyrin backbone bearing two pyridyl interaction sites, one at the meso position of the porphyrin and the other on the handle connected to the porphyrin through P-O bonds, was designed and synthesized. The dynamic behavior of the turnstile 2, investigated by 1D and 2D 1H NMR techniques, showed that in the absence of an effector, the turnstile is in its open state and undergoes a free rotation of the rotor (the handle) around the stator (the porphyrin backbone). In the presence of an external effector such as Ag+ cation or H+, the turnstile is switched to its closed states 2-Ag+ and 2 H+, respectively. The locking/unlocking process is reversible and may be achieved by precipitation of AgBr upon addition of Et4NBr in the case of the silver-locked turnstile or by addition of Et3N in the case of the proton-locked turnstile. PMID- 27704798 TI - The Mn4Ca-cluster of the photosynthetic oxygen evolving centre: its structure, function and evolution. AB - Photosystem II is the chlorophyll containing enzyme in which the very first chemical energy storing reaction of photosynthesis occurs. It does so by splitting water into molecular oxygen and hydrogen equivalents at a catalytic centre composed of four Mn ions and one Ca2+. All the oxygen in the atmosphere is derived from this reaction and without it the biosphere, as we know it, would not exist. Indeed its appearance about 3 billion years ago gave rise to the "big bang of evolution". Thus understanding the structure and functioning of this metal cluster is a major topic in science and here I discuss it in terms of research over of the last twelve years dating back to when it was first proposed to be a Mn3CaO4 cubane with the fourth Mn attached to cubane by one of its oxo bridging bonds. In so doing a number of novel properties emerge for this metallo-protein with implications for its mechanism and evolutionary origin.

AB - We applied spectroscopy, microscopy, diffraction, and aqueous chemistry methods to investigate the persistence of metals in water and sediments from the Animas River 13 days after the Gold King Mine spill (August 5, 2015). The Upper Animas River watershed, located in San Juan Colorado, is heavily mineralized and impacted by acid mine drainage, with low pH water and elevated metal concentrations in sediments (108.4 +/- 1.8 mg kg-1 Pb, 32.4 +/- 0.5 mg kg-1 Cu, 729.6 +/- 5.7 mg kg-1 Zn, and 51 314.6 +/- 295.4 mg kg-1 Fe). Phosphate and nitrogen species were detected in water and sediment samples from Farmington, New Mexico, an intensive agricultural area downstream from the Animas River, while metal concentrations were low compared to those observed upstream. Solid-phase analyses of sediments suggest that Pb, Cu, and Zn are associated with metal bearing jarosite and other minerals (e.g., clays, Fe-(oxy)hydroxides). The solubility of jarosite at near-neutral pH and biogeochemical processes occurring downstream could affect the stability of metal-bearing minerals in river sediments. This study contributes relevant information about the association of metal mixtures in a heavy mineralized semiarid region, providing a foundation to better understand long-term metal release in a public and agricultural water supply. PMID- 27704801 TI - Complex Microstructure and Magnetism in Polymorphic CaFeSeO. AB - The structural complexity of the antiferromagnetic oxide selenide CaFeSeO is described. The compound contains puckered FeSeO layers composed of FeSe2O2 tetrahedra sharing all their vertexes. Two polymorphs coexist that can be derived from an archetype BaZnSO structure by cooperative tilting of the FeSe2O2 tetrahedra. The polymorphs differ in the relative arrangement of the puckered layers of vertex-linked FeSe2O2 tetrahedra. In a noncentrosymmetric Cmc21 polymorph (a = 3.89684(2) A, b = 13.22054(8) A, c = 5.93625(2) A) the layers are related by the C-centering translation, while in a centrosymmetric Pmcn polymorph, with a similar cell metric (a = 3.89557(6) A, b = 13.2237(6) A, c = 5.9363(3) A), the layers are related by inversion. The compound shows long-range antiferromagnetic order below a Neel temperature of 159(1) K with both polymorphs showing antiferromagnetic coupling via Fe-O-Fe linkages and ferromagnetic coupling via Fe-Se-Fe linkages within the FeSeO layers. The magnetic susceptibility also shows evidence for weak ferromagnetism which is modeled in the refinements of the magnetic structure as arising from an uncompensated spin canting in the noncentrosymmetric polymorph. There is also a spin glass component to the magnetism which likely arises from the disordered regions of the structure evident in the transmission electron microscopy. PMID- 27704802 TI - Molecular Characterization of Brown Carbon in Biomass Burning Aerosol Particles. AB - Emissions from biomass burning are a significant source of brown carbon (BrC) in the atmosphere. In this study, we investigate the molecular composition of freshly emitted biomass burning organic aerosol (BBOA) samples collected during test burns of sawgrass, peat, ponderosa pine, and black spruce. We demonstrate that both the BrC absorption and the chemical composition of light-absorbing compounds depend significantly on the type of biomass fuels. Common BrC chromophores in the selected BBOA samples include nitro-aromatics, polycyclic aromatic hydrocarbon derivatives, and polyphenols spanning a wide range of molecular weights, structures, and light absorption properties. A number of biofuel-specific BrC chromophores are observed, indicating that some of them may be used as source-specific markers of BrC. On average, ~50% of the light absorption in the solvent-extractable fraction of BBOA can be attributed to a limited number of strong BrC chromophores. The absorption coefficients of BBOA are affected by solar photolysis. Specifically, under typical atmospheric conditions, the 300 nm absorbance decays with a half-life of ~16 h. A "molecular corridor" analysis of the BBOA volatility distribution suggests that many BrC compounds in the fresh BBOA have low saturation mass concentration (<1 MUg m-3) and will be retained in the particle phase under atmospherically relevant conditions.

AB - The kinetics of the reaction of Ph3SnH with excess *Cr(CO)3C5Me5 = *Cr, producing HCr and Ph3Sn-Cr, was studied in toluene solution under 2-3 atm CO pressure in the temperature range of 17-43.5 degrees C. It was found to obey the rate equation d[Ph3Sn-Cr]/dt = k[Ph3SnH][*Cr] and exhibit a normal kinetic isotope effect (kH/kD = 1.12 +/- 0.04). Variable-temperature studies yielded DeltaH? = 15.7 +/- 1.5 kcal/mol and DeltaS? = -11 +/- 5 cal/(mol.K) for the reaction. These data are interpreted in terms of a two-step mechanism involving a thermodynamically uphill hydrogen atom transfer (HAT) producing Ph3Sn* and HCr, followed by rapid trapping of Ph3Sn* by excess *Cr to produce Ph3Sn-Cr. Assuming an overbarrier of 2 +/- 1 kcal/mol in the HAT step leads to a derived value of 76.0 +/- 3.0 kcal/mol for the Ph3Sn-H bond dissociation enthalpy (BDE) in toluene solution. The reaction enthalpy of Ph3SnH with excess *Cr was measured by reaction calorimetry in toluene solution, and a value of the Sn-Cr BDE in Ph3Sn Cr of 50.4 +/- 3.5 kcal/mol was derived. Qualitative studies of the reactions of other R3SnH compounds with *Cr are described for R = nBu, tBu, and Cy. The dehydrogenation reaction of 2Ph3SnH -> H2 + Ph3SnSnPh3 was found to be rapid and quantitative in the presence of catalytic amounts of the complex Pd(IPr)(P(p tolyl)3). The thermochemistry of this process was also studied in toluene solution using varying amounts of the Pd(0) catalyst. The value of DeltaH = -15.8 +/- 2.2 kcal/mol yields a value of the Sn-Sn BDE in Ph3SnSnPh3 of 63.8 +/- 3.7 kcal/mol. Computational studies of the Sn-H, Sn-Sn, and Sn-Cr BDEs are in good agreement with experimental data and provide additional insight into factors controlling reactivity in these systems. The structures of Ph3Sn-Cr and Cy3Sn-Cr were determined by X-ray crystallography and are reported. Mechanistic aspects of oxidative addition reactions in this system are discussed.

AB - Specialized pro-resolving lipid mediators are biosynthesized during the resolution phase of acute inflammation from n-3 polyunsaturated fatty acids. Recently, the isolation and identification of the four novel mediators denoted 13 series resolvins, namely, RvT1 (1), RvT2 (2), RvT3 (3) and RvT4 (4), were reported, which showed potent bioactions characteristic for specialized pro resolving lipid mediators. Herein, based on results from LC/MS-MS metabololipidomics and the stereoselective synthesis of 13(R)-hydroxy 7Z,10Z,13R,14E,16Z,19Z docosapentaenoic acid (13R-HDPA, 5), we provide direct evidence that the four novel mediators 1-4 are all biosynthesized from the pivotal intermediate 5. The UV and LC/MS-MS results from synthetic 13R-HDPA (5) matched those from endogenously and biosynthetically produced material obtained from in vivo infectious exudates, endothelial cells, and human recombinant COX-2 enzyme. Stereochemically pure 5 was obtained with the use of a chiral pool starting material that installed the configuration at the C-13 atom as R. Two stereoselective Z-Wittig reactions and two Z-selective reductions of internal alkynes afforded the geometrically pure alkene moieties in 5. Incubation of 5 with isolated human neutrophils gave all four RvTs. The results presented herein provide new knowledge on the biosynthetic pathways and the enzymatic origin of RvTs 1-4.

AB - A highly selective cascade reaction that allows the direct transformation of dienallenes to spirocyclobutenes (spiro[3.4]octenes) as single isomers has been developed. The reaction involves formation of overall four C-C bonds and proceeds via a palladium-catalyzed oxidative transformation with insertion of olefin, olefin, and carbon monoxide. Under slightly different reaction conditions an additional CO insertion takes place to give spiro[4.4]nonenes with formation of overall five C-C bonds. PMID- 27704806 TI - Eutrophication Increases Phytoplankton Methylmercury Concentrations in a Coastal Sea-A Baltic Sea Case Study. AB - Eutrophication is expanding worldwide, but its implication for production and bioaccumulation of neurotoxic monomethylmercury (MeHg) is unknown. We developed a mercury (Hg) biogeochemical model for the Baltic Sea and used it to investigate the impact of eutrophication on phytoplankton MeHg concentrations. For model evaluation, we measured total methylated Hg (MeHgT) in the Baltic Sea and found low concentrations (39 +/- 16 fM) above the halocline and high concentrations in anoxic waters (1249 +/- 369 fM). To close the Baltic Sea MeHgT budget, we inferred an average normoxic water column HgII methylation rate constant of 2 * 10-4 d-1. We used the model to compare Baltic Sea's present-day (2005-2014) eutrophic state to an oligo/mesotrophic scenario. Eutrophication increases primary production and export of organic matter and associated Hg to the sediment effectively removing Hg from the active biogeochemical cycle; this results in a 27% lower present-day water column Hg reservoir. However, increase in organic matter production and remineralization stimulates microbial Hg methylation resulting in a seasonal increase in both water and phytoplankton MeHg reservoirs above the halocline. Previous studies of systems dominated by external MeHg sources or benthic production found eutrophication to decrease MeHg levels in plankton. This Baltic Sea study shows that in systems with MeHg production in the normoxic water column eutrophication can increase phytoplankton MeHg content. PMID- 27704809 TI - Regulation of DNA Strand Displacement Using Allosteric DNA Toehold. AB - Toehold-mediated DNA strand displacement is the fundamental basis for the construction and operation of diverse DNA devices, including circuits, machines, sensors, and reconfigurable structures. Controllable activation and regulation of toeholds are critical to construct devices with multistep, autonomous, and complex behaviors. A handful of unique toehold activation mechanisms, including toehold-exchange, associative toehold, and remote toehold, have been developed and are often combined to achieve desired strand displacement behaviors and functions. Here we report an allosteric DNA toehold (A-toehold) design that allows the flexible regulation of DNA strand displacement by splitting an input strand into an A-toehold and branch migration domain. Because of its simplicity, the A-toehold mechanism can be a useful addition to the current toolbox of DNA strand displacement techniques. We demonstrated that A-toehold enabled a number of interesting functions that were previously shown using more sophisticated DNA strand displacement systems, including 1) continuously tuning the rate of strand displacement, 2) dynamic control of strand displacement reactions, and 3) selective activation of multiple strand displacement reactions. Moreover, by combining A-toehold and toehold-exchange mechanisms, we have successfully constructed a non-covalent DNA catalysis network that resembles an allosteric enzyme.

AB - Fourteen new rearranged 6/6/5/6-fused triterpenoid acids, namely, kadcoccine acids A-N (1-14), were isolated from an EtOAc-soluble extract of the stems of Kadsura coccinea. Their structures were characterized mainly by analyzing 1D and 2D NMR and HRESIMS data and were shown to feature a rare 14(13->12)-abeo lanostane skeleton. Compounds 7 and 8 represented the first examples of a 5 substituted 2(5H)-furanone motif on the C-17 side chain of this skeleton. The absolute configurations of C-23 for compounds 1, 7, and 8 were determined by comparison of their experimental electronic circular dichroism spectra. All the isolates were screened for their in vitro cytotoxicity against six human tumor cell lines (HL-60, SMMC-7721, A-549, MCF-7, SW-480, and HeLa), and compounds 2 and 8 exhibited weak inhibitory effects with IC50 values ranging from 3.11 to 7.77 MUM.

The bissubvilides represent a novel biscembranoid-like skeleton presumed to derive from a cembrane-type diene and a capnosane-type dienophile via a Diels-Alder reaction. These two molecules exerted no cytotoxicity against MG-63 or A549 tumor cells or HuH7 tumor stem cells.

Mechanistic insights guide develop-ment of this linking strategy to favor substrate activation though the intramolecular cooperation of two thiourea sub-units while avoiding nonproductive aggregation. The resulting catalyst platform overcomes many of the practical limitations that have plagued hydrogen-bond donor catalysis and enables use of catalyst loadings as low as 0.05 mol %.

PMID- 27704812 TI - Effective Fully Polarizable QM/MM Approach To Model Vibrational Circular Dichroism Spectra of Systems in Aqueous Solution. AB - We propose a methodology, based on the combination of classical Molecular Dynamics (MD) simulations with a fully polarizable Quantum Mechanical (QM)/Molecular Mechanics (MM)/Polarizable Continuum Model (PCM) Hamiltonian, to calculate Vibrational Circular Dichroism (VCD) spectra of chiral systems in aqueous solution. Polarization effects are included in the MM force field by exploiting an approach based on Fluctuating Charges (FQ). By performing the MD, the description of the solvating environment is enriched by taking into account the dynamical aspects of the solute-solvent interactions. On the other hand, the QM/FQ/PCM calculation of the VCD spectrum ensures an accurate description of the electronic density of the solute and a proper account for the specific interactions in solution. The application of our approach to (R)-methyloxirane and (l)-alanine in aqueous solution gives calculated spectra in remarkable agreement with their experimental counterparts and a substantial improvement with respect to the same spectra calculated with the PCM.

AB - Phytochemical investigation of the roots of the African medicinal plant Tabernaemontana elegans led to the isolation of three new (1-3) and two known (4 and 5) bisindole alkaloids of the vobasinyl-iboga type. The structures of 1-3 were assigned by spectroscopic methods, mainly using 1D and 2D NMR experiments. All of the isolated compounds were evaluated for their cytotoxicity against HCT116 colon and HepG2 liver carcinoma cells by the MTS metabolism assay. Compounds 1-3 and 5 were found to be cytotoxic to HCT116 colon cancer cells, displaying IC50 values in the range 8.4 to >10 MUM. However, the compounds did not display significant cytotoxicity against HepG2 cancer cells. The cytotoxicity of compounds 1-3 and 5 was corroborated using a lactate dehydrogenase assay. Hoechst staining and nuclear morphology assessment and caspase-3/7 activity assays were also performed for investigating the activity of compounds 1-3 and 5 as apoptosis inducers. The induced inhibition of proliferation of HCT116 cells by compounds 1 and 2 was associated with G1 phase arrest, while compounds 3 and 5 induced G2/M cell cycle arrest. These results showed that the new vobasinyl-iboga alkaloids 1-3 and compound 5 are strong inducers of apoptosis and cell cycle arrest in HCT116 colon cancer cells.

AB - The abnormal proliferation and migration of vascular smooth muscle cells (VSMCs) are associated with cardiovascular diseases and related complications. Such deleterious proliferation and migration events are triggered by cytokines and growth factors, and among them, platelet-derived growth factor (PDGF) is recognized as the most potent inducer. Despite the genus Rubia being researched to identify valuable commercial and medicinal virtues, Rubia philippinensis has rarely been investigated. Nine arborinane-type triterpenoids (1-9) were identified from this underutilized plant species. In particular, 4 was identified as the first arborinane derivative carrying a ketocarbonyl motif at C-19. The presence of the cyclopentanone moiety and the associated configurational assignment were determined by utilizing NOE and coupling constant analysis. These compounds were assessed for their inhibitory potential on PDGF-induced proliferation and the migration of VSMCs. Treatment with 5 MUM compound 5 (62.6 +/- 10.7%) and compound 9 (41.1 +/- 4.7%) impeded PDGF-stimulated proliferation without exerting cytotoxicity. Compound 7 exhibited antimigration activity in a dose-dependent manner (38.5 +/- 3.0% at 10 MUM, 57.6 +/- 3.2% at 30 MUM). These results suggest that the arborinane-type triterpenoids may be a pertinent starting point for the development of cardiovascular drugs capable of preventing the intimal accumulation of VSMCs.

AB - The total syntheses of 12-epoxyobtusallene IV, 12-epoxyobtusallene II, obtusallene X, marilzabicycloallene C, and marilzabicycloallene D as halogenated C15-acetogenin 12-membered bicyclic and tricyclic ether bromoallene-containing marine metabolites from Laurencia species are described. Two enantiomerically pure C4-epimeric dioxabicyclo[8.2.1]tridecenes were synthesized by E-selective ring-closing metathesis where their absolute stereochemistry was previously set via catalytic asymmetric homoallylic epoxidation and elaborated via regioselective epoxide-ring opening and diastereoselective bromoetherification. Epimeric face-selective oxidation of their Delta12,13 olefins followed by bromoallene installation allowed access to the oppositely configured 12,13 epoxides of 12-epoxyobtusallene II and 12-epoxyobtusallene IV. Subsequent exploration of their putative biomimetic oxonium ion formation-fragmentations reactions revealed diastereodivergent pathways giving marilzabicycloallene C and obtusallene X, respectively. The original configurations of the substrates evidently control oxonium ion formation and their subsequent preferred mode of fragmentation by nucleophilic attack at C9 or C12. Quantum modeling of this stereoselectivity at the omegaB97X-D/Def2-TZVPPD/SCRF = methanol level revealed that in addition to direction resulting from hydrogen bonding, the dipole moment of the ion-pair transition state is an important factor. Marilzabicycloallene D as a pentahalogenated 12-membered bicyclic ether bromoallene was synthesized by a face-selective chloronium ion initiated oxonium ion formation-fragmentation process followed by subsequent bromoallene installation.

AB - We report a simple strategy for the creation of large-area nanoporous hybrid films of silica, carbon, and gold on polyethylene terephthalate via photothermal processing. This method enables the selective heating of light-absorbing thin films on low-temperature substrates using submillisecond light pulses generated by a xenon flash lamp. The film contains gold nanoparticles as the nano-heaters to convert light energy into heat, a sacrificial block copolymer surfactant to generate mesopores, and cross-linked polyhedral oligomeric silsesquioxane (POSS) as the silica source to form the skeleton of the porous structure. Hierarchical porous structures are achieved in the films after photothermal treatment with uniform mesopores (44~48 nm) on the surface and interconnected macropores (>50 nm) underneath resulting from a foaming effect during release gaseous decomposition products. The loading of gold nanoparticles is up to 43 wt % in the product with less than 2 wt % organic residue. This rapid and large-area synthetic process of porous structures is compatible with roll-to-roll manufacturing for the fabrication of flexible devices.

AB - Five new diterpenes (1-5) and a megastigmane derivative (6) were isolated from the aerial parts of Euphorbia laurifolia, along with several known compounds. Their structures were elucidated by NMR, MS, and ECD and by chemical methods. A chemical proteomics drug affinity responsive target stability (DARTS) approach to investigate the lathyrane diterpene 1, laurifolioside, on its putative cellular target(s) was performed. Clathrin heavy chain 1, a protein mainly involved in selective uptake of proteins, viruses, and other macromolecules at the plasma membrane of cells, was identified as the major interaction partner of compound 1. The modulation of clathrin activity by 1 was studied through microscopy, molecular docking, and molecular dynamics studies, suggesting a new activity of lathyrane diterpenes in the modulation of trafficking pathways. PMID- 27704817 TI - Oxytetracycline Toxicity and its Effect on Phytoremediation by Sedum Plumbizincicola and Medicago Sativa in Metal Contaminated Soil. AB - Excessive use of antibiotics potentially threatens human health, agricultural production and soil phytoremediation. This arouses concern over the potential adverse effects of a commonly used antibiotic, oxytetracycline (OTC), on plants used for soil remediation and possible stimulation of antibiotic resistance genes in soils. A greenhouse experiment was conducted to investigate different rates (0, 1, 5, and 25 mg kg-1) and frequencies (one single high and daily low application) of OTC addition to soil on phytoremediation of a heavy metal contaminated soil by Sedum plumbizincicola and/or Medicago sativa (alfalfa). After 90 days both Cd and Zn were substantially removed by phytoextraction into S. plumbizincicola shoots especially at the high OTC (25 mg kg-1) treatment which also led to inhibition of anti-oxidative enzyme activities in both plant species. Soil microbial activity decreased significantly with the addition of OTC and this was ameliorated by planting alfalfa and S. plumbizincicola together. OTC at < 5 mg kg-1 increased the biomass of both plant species but the frequency of OTC addition had no effect on the rate of metal removal. Alfalfa exhibited greater detoxification ability and effectiveness in soil microbial activity promotion than S. plumbizincicola with intercropping.

AB - An atom-economical Pd-catalyzed approach for the synthesis of benzophenazine derivatives using substituted 2-aryl-3-(aryl/alkylethynyl) quinoxaline in the presence of trifluoroacetic acid at 65 degrees C has been described. The chemistry involves in situ generation of cationic Pd(II) species, which functionalized the aromatic C-H bonds via electrophilic metalation followed by concomitant intramolecular trans-insertion of C-C triple bond to aryl-Pd complex. The results were supported by various control experiments including with electron deficient arenes and deuterium labeling studies. The deuterium labeling studies supports electrophilic palladation of aromatic C-H over activation of C-C triple bond of alkyne. The structure of synthesized compounds was further confirmed by X ray crystallography studies. This catalytic protocol has been efficiently applied for novel synthesis of highly functionalized benzo fused phenazines. PMID- 27704819 TI - Photocatalytic Reduction of Low Concentration of CO2. AB - A novel molecular photocatalytic system with not only high reduction ability of CO2 but also high capture ability of CO2 has been developed using a Ru(II)-Re(I) dinuclear complex as a photocatalyst. By using this photocatalytic system, CO2 of 10% concentration could be selectively converted to CO with almost same photocatalysis to that under a pure CO2 atmosphere (TONCO > 1000, PhiCO > 0.4). Even 0.5% concentration of CO2 was reduced with 60% initial efficiency of CO formation by using the same system compared to that using pure CO2 (TONCO > 200). The Re(I) catalyst unit in the photocatalyst can efficiently capture CO2, which proceeds CO2 insertion to the Re-O bond, and then reduce the captured CO2 by using an electron supplied from the photochemically reduced Ru photosensitizer unit.

AB - Six new heteroaromatic polycyclic azaborine chromophores were designed, synthesized, and investigated as easily tunable high-luminescent organic materials. The impact of the nitrogen-boron-hydroxy (N-BOH) unit in the azaborines was investigated by comparison with their N-carbonyl analogs. Insertion of the N-B(OH)-C unit into heteroaromatic polycyclic compounds resulted in strong visible absorption and sharp fluorescence with efficient quantum yields. The solid-state fluorescence of the heteroaromatic polycyclic compounds displayed a large Stokes shift compared to being in solution. The large Stokes shifts observed offset the self-quench effect in the solid state. PMID- 27704821 TI - Discovery and Development of the Anti-Human Immunodeficiency Virus Drug, Emtricitabine (Emtriva, FTC). AB - The HIV/AIDS epidemic, which was first reported on in 1981, progressed in just 10 years to a disease afflicting 10 million people worldwide including 1 million in the US. In 1987, AZT was approved for treating HIV/AIDS. Unfortunately, its clinical usefullness was severly limited by associated toxicities and the emergence of resistance. Three other drugs that were approved in the early 1990s suffered from similar liabilities. In 1990, the Liotta group at Emory University developed a highly diastereoselective synthesis of racemic 3'-thia-2',3' dideoxycytidine and 3'-thia-2',3'-5-fluorodideoxycytidine and demonstrated that these compounds exhibited excellent anti-HIV activity with no apparent cytotoxicity. Subsequently, the enantiomers of these compounds were separated using enzyme-mediated kinetic resolutions and their (-)-enantiomers (3TC and FTC, respectively) were found to have exceptionally attractive preclinical profiles. In addition to their anti-HIV activity, 3TC and FTC potently inhibit the replication of hepatitis B virus. The development of FTC, which was being carried out by Burroughs Wellcome, had many remarkable starts and stops. For example, passage studies indicated that the compound rapidly selected for a single resistant mutant, M184V, and that this strain was 500-1000-fold less sensitive to FTC than was wild-type virus. Fortunately, it was found that combinations of AZT with either 3TC or FTC were synergistic. The effectiveness of AZT-3TC combination therapy was subsequently demonstrated in four independent clinical trials, and in 1997, the FDA approved Combivir, a fixed dose combination of AZT and 3TC. In phase 1 clinical trials, FTC was well tolerated by all subjects with no adverse events observed. However, the development of FTC was halted by the aquistition of Wellcome PLC by Glaxo PLC in January 1995. In 1996, Triangle Pharmaceuticals licensed FTC from Emory and initiated a series of phase I/II clinical studies that demonstrated the safety and efficacy of the drug. In August 1998, FTC was granted "Fast Track" status, based primarily on its potential for once daily dosing. While the outcomes of two subsequent phase III trials were positive, a third phase III clinical trial involving combinations of 3TC or FTC with stavudine and neviripine had to be terminated due to serious liver-related adverse events. Although analysis of the data suggested that the liver toxicity was due to neviripine, the FDA decided that the study could not be used for drug registration. Ultimately, in January 2003, Gilead Sciences acquired Triangle Pharmaceuticals and completed the development of FTC (emtricitabine), which was approved for once a day, oral administration in July 2003. A year later, Truvada, a once a day, oral, fixed dose combination of emtricitabine and tenofovir disoproxyl fumarate received FDA approval and quickly became the accepted first line therapy when used with a third antiretroviral agent. In July 2006, the FDA approved Atripla, a once a day, oral, fixed dose combination of emtricitabine, tenofovir disoproxyl fumarate, and efavirenz, which represented the culmination of two decades of research that had transformed AIDS from a death sentence to a manageable chronic disease.

AB - A pair of enantiomers and a pair of 2,3-dihydro-1H-indene epimers, rac-indidene A (rac-1), indidenes B and C (2, 3); four new coumarin glucosides (4-7); and four known coumarin glucosides (8-11) were isolated from the bark of Streblus indicus (Bur.)

AB - The mechanism and dynamics for the formation of a hydrogen molecule in the cavity of POSS (polyhedral oligomeric silsesquioxane) compounds have been investigated by ab initio molecular orbital and ab initio molecular dynamics (AIMD) methods. The host molecules are two POSS compounds, T8 ([HSiO1.5]8) (Oh) and T12 ([HSiO1.5]12) (D2d). To investigate the H2 formation reaction, two approaches were considered: trajectories were initiated by inserting a second hydrogen atom into (I) a hydrogen molecule encapsulated-POSS (H + H2@Tn -> (H + H2)@Tn; n = 8, 12), and (II) the hydrogen atom and hydrogen molecule-encapsulated-POSS (H + (H + H2)@Tn -> 2 H2@Tn; n = 8 and 12). A wide variety of reactions were observed depending on the system and the initial conditions, especially in process II. Therefore, for reaction II, an energy decomposition analysis was employed to examine the variation of the distribution of the translational, rotational and vibrational kinetic energies of the guest species along the reaction processes, and to determine the role of each energy component for the H2 formation. This analysis provides important insights into the expected kinetic energy distributions among the products of encapsulation reactions.

AB - Derivatives of geraniol are versatile synthetic intermediates that are useful for synthesizing a variety of terpenoid natural products; however, the results presented herein show that subtle differences in the structures of functionalized geranyl chlorides can significantly impact their abilities to function as effective electrophiles in synthetic reactions. A series of focused kinetics experiments identify specific structure-activity relationships that illustrate the importance not only of steric bulk, but also of electronic effects from distant regions of the molecules that contribute to their overall levels of reactivity. Computational modeling suggests that destabilization of the reactant by filled-filled orbital mixing events in some, but not all, conformations may be a critical contributor to these important electronic effects. PMID- 27704825 TI - Ejection of Metal Particles into Superfluid 4He by Laser Ablation. AB - The dynamics following laser ablation of a metal target immersed in superfluid $^4$He is studied by time-resolved shadowgraph photography. The delayed ejection of hot micrometer-sized particles from the target surface into the liquid was indirectly observed by monitoring the formation and growth of gaseous bubbles around the particles. The experimentally determined particle average velocity distribution appears similar as previously measured in vacuum but exhibits a sharp cutoff at the speed of sound of the liquid. The propagation of the subsonic particles terminates in slightly elongated non-spherical gas bubbles residing near the target whereas faster particles reveal an unusual hydrodynamic response of the liquid. Based on the previously established semi-empirical model developed for macroscopic objects, the ejected transonic particles exhibit supercavitating flow to reduce their hydrodynamic drag. Supersonic particles appear to follow a completely different propagation mechanism as they leave discrete and semi continuous bubble trails in the liquid. The relatively low number density of the observed non-spherical gas bubbles indicates that only large micron-sized particles are visualized in the experiments. Although the unique properties of superfluid helium allow a detailed characterization of these processes, the developed technique can be used to study the hydrodynamic response of any liquid to fast propagating objects on the micrometer-scale.

AB - The adsorption kinetics and equilibrium of amphiphilic dendrimers based on poly(amidoamine) PAMAM modified with dodecyl chain GnQPAMC12(n represents the generation number) with different generation at silica-water interface have been investigated. The effect of molecular shape with different charge characteristics on the adsorption kinetics, adsorption isotherms and the conformation of self assembled layer has been elucidated. For the adsorption kinetics, two steps were observed including the adsorption of individual molecules at the concentrations below cmc and the predominant adsorption of aggregates above cmc. However, the adsorption isotherm, with the generation number as a function, presented exceptional characteristic, in which, a decrease of adsorption mass with different levels occurred in high generation of amphiphilicdendrimers, depending on the balance of hydrophobic interaction and electrostatic repulsion. Atomic force microscopy imaging showed that flatten films with pores (spacing) of various shapes and roughness of 3 ~ 4 nm were formed, of which the pores (spacing) decreased obviously as the generation increases. The addition of electrolyte (NaBr) has great effect on the film morphology formed by G3QPAMC12 dendrimer adsorbed at silica-water interface, showing that the film became closer with smaller pores with increased NaBr concentration.

AB - A benzene ring substituted with 1-3 thiourea containing arms (1-3) were examined by photoelectron spectroscopy and density functional theory computations. Their conjugate bases and chloride, acetate and dihydrogen phosphate anion clusters are reported. The resulting vertical and adiabatic detachment energies span from 3.93 - 5.82 eV (VDE) and 3.65 - 5.10 (ADE) for the deprotonated species and 4.88 - 5.97 eV (VDE) and 4.45 - 5.60 eV (ADE) for the anion complexes. These results reveal the stabilizing effects of multiple hydrogen bonds and anionic host-guest interactions in the gas phase. Previously measured equilibrium binding constants in aqueous dimethyl sulfoxide for all three thioureas are compared to the present results and cooperative binding is uniformly observed in the gas phase but only for one case (i.e., 3 * H2PO4-) in solution.

PMID- 27704827 TI - How Large Should the QM Region Be in QM/MM Calculations? The Case of Catechol O Methyltransferase. AB - Hybrid quantum mechanical-molecular mechanical (QM/MM) simulations are widely used in studies of enzymatic catalysis. Until recently, it has been cost prohibitive to determine the asymptotic limit of key energetic and structural properties with respect to increasingly large QM regions. Leveraging recent advances in electronic structure efficiency and accuracy, we investigate catalytic properties in catechol O-methyltransferase, a prototypical methyltransferase critical to human health. Using QM regions ranging in size from reactants-only (64 atoms) to nearly one-third of the entire protein (940 atoms), we show that properties such as the activation energy approach within chemical accuracy of the large-QM asymptotic limits rather slowly, requiring approximately 500-600 atoms if the QM residues are chosen simply by distance from the substrate. This slow approach to asymptotic limit is due to charge transfer from protein residues to the reacting substrates. Our large QM/MM calculations enable identification of charge separation for fragments in the transition state as a key component of enzymatic methyl transfer rate enhancement. We introduce charge shift analysis that reveals the minimum number of protein residues (approximately 11-16 residues or 200-300 atoms for COMT) needed for quantitative agreement with large-QM simulations. The identified residues are not those that would be typically selected using criteria such as chemical intuition or proximity. These results provide a recipe for a more careful determination of QM region sizes in future QM/MM studies of enzymes.

AB - Highly active catalytic clusters are observed during the reaction mechanism study of the copper cluster Cux (x = 4-15) catalyzed N2O + CO -> N2 + CO2 reaction. It was shown that N2O adsorbs on the copper cluster without an activation barrier and the nitrogen-oxygen bond is broken during the next step. The analysis of the chemical bonding showed that the oxide ion formation is an important driving force of the reaction. Among the different clusters Cu12 was the most active as the nitrogen-oxygen bond is cleaved without an energy barrier, while the nitrogen molecule is eliminated. It was shown that the resulting copper oxide cluster is reduced easily with carbon-monoxide. The elimination of the thus formed carbon dioxide is thermodynamically a highly favored process, even at low temperature. Thus, Cu12 cluster is a potentially highly active catalyst at ambient condition for the N2O + CO -> N2 + CO2 reaction.

AB - Vibronic interactions in the two energetically lowest electronic states (X2Pig A2Piu) of the diacetylene radical cation (C4H2*+) are theoretically examined here. The spectroscopy of these two electronic states of C4H2*+ has been a subject of considerable interest and measured in the laboratory by various groups. Inspired by numerous experimental data, we attempt here a detailed investigation of vibronic interactions within and between the doubly degenerate Pi electronic states and their impact on the vibronic structure of each state. A vibronic coupling model is constructed in a diabatic electronic basis and with the aid of ab initio quantum chemistry calculations. The vibronic structures of the electronic states are calculated by time-independent and time-dependent quantum mechanical methods. The progression of vibrational modes in the vibronic band is identified, assigned, and compared with the literature data. The nonradiative internal conversion dynamics is also examined and discussed. PMID- 27704834 TI - Theoretical Study of the Catalytic Hydrogenation of Alkenes by a Disilaferracyclic Complex: Can the Fe-Si sigma-Bond-Assisted Activation of H-H Bonds Allow Development of a Catalysis of Iron? AB - The mechanisms associated with the hydrogenation of alkenes catalyzed by the iron complex Fe(cis-CO)2{o-(SiMe2)2C6H4}2(H)2 (1) were investigated by DFT calculations. The complex 1 has a structure in which the iron center is bonded to four silicon atoms and two hydrides. Secondary Si...H...Si interactions were also observed. The exchange of a 1,2-bis(dimethylsilyl)benzene ligand with ethylene and hydrogen gives a disilaferracycle bearing eta2-(CH2?CH2) and eta2-H2 ligands. The catalytic cycle initiated from the disilaferracycle involves cleavage of a H H linkage assisted by an Fe-Si bond to form Fe-H and eta1-(H-Si) moieties (step 1), hydrogen migration from the Fe-H group to the eta2-(CH2?CH2) ligand which accomplishes the insertion of ethylene into the Fe-H bond (step 2), and reaction of the resulting beta-agostic ethyl moiety with the eta2-(H-Si) group to form ethane on the iron atom (step 3). The octahedral geometry of 1 as well as the presence of pi-acidic CO ligands and Fe-Si sigma-bonds contributes to all of the catalytic intermediates and the transition states being in the low-spin state. Steps 1 and 3 correspond to the sigma-complex-assisted metathesis (sigma-CAM) mechanisms proposed by Perutz and Sabo-Etienne, suggesting that these mechanisms can assist in the design of iron-based hydrogenation catalysts operating under mild conditions.

AB - The electroreductive coupling of coumarins with benzophenones in the presence of TMSCl gave adducts reacted at the 4-position of coumarins as trimethylsilyl ethers. From 3-methylcoumarin, 3,4-cis-adducts were formed stereoselectively. The de-trimethylsilylation of the adducts with 1 M HCl aq or TBAF in THF at 25 degrees C produced 4-(2-hydroxyphenyl)-5,5-diaryl-gamma-butyrolactones. The gamma butyrolactones were further transformed to 2-(2,2-diaryl-2,3-dihydrobenzofuran-3 yl)acetic acids by treatment with 1 M HCl aq at reflux temperature. The de trimethylsilylation of the adducts with 1 M HCl in MeOH afforded 2-(2,2-diaryl 2,3-dihydrobenzofuran-3-yl)acetic acid methyl esters. The de trimethylsiloxylation of the adducts or dehydration of the gamma-butyrolactones brought about 4-(diarylmethyl)coumarins.

AB - We present high-resolution near-edge X-ray absorption fine structure (NEXAFS) measurements at the P L2/3 edges, F K edge, C K edge, and Se M2/3 edges of the quasi-one-dimensional (1D) conductor and superconductor (TMTSF)2PF6. NEXAFS allows probing the donor and acceptor moieties separately; spectra were recorded between room temperature (RT) and 30 K at normal incidence. Spectra taken around RT were also studied as a function of the angle (theta) between the electric field of the X-ray beam and the 1D conducting direction. In contrast with a previous study of the S L2/3-edges spectra in (TMTTF)2AsF6, the Se M2/3 edges of (TMTSF)2PF6 do not exhibit a well-resolved spectrum. Surprisingly, the C K-edge spectra contain three well-defined peaks exhibiting strong and nontrivial theta and temperature dependence. The nature of these peaks as well as those of the F K edge spectra could be rationalized on the basis of first-principles DFT calculations. Despite the structural similarity, the NEXAFS spectra of (TMTSF)2PF6 and (TMTTF)2AsF6 exhibit important differences. In contrast with the case of (TMTTF)2AsF6, the F K-edge spectra of (TMTSF)2PF6 do not change with temperature despite stronger donor-anion interactions. All these features reveal subtle differences in the electronic structure of the TMTSF and TMTTF families of salts.

AB - Advanced glycation end-products (AGEs) are nonenzymatically glycated proteins, lipids, and nucleic acids. These compounds both originate exogenously and are formed endogenously, and they are associated, along with one of their receptors (RAGE), with a variety of pathologies and neurodegeneration. Some of their deleterious effects include affecting insulin signaling and FOXO-related pathways in both receptor-dependent and -independent manners. A potential ameliorating agent for these effects is insulin, which is being studied in several in vivo and in vitro models; one of these models is C. elegans, whose maintenance, genetic malleability, and well-described longevity-related pathways make it an optimal complementary model for assessing these objectives. In the realm of neuroscience, this model is currently being used only for general assessment of neurodegeneration and shortened lifespan. We suggest that characterization of (a) the effects of AGEs/RAGE on specific neurotransmitter systems, (b) the role of the daf-2/daf-16 pathway in these neurodegenerative processes, and PMID- 27704839 TI - That Little Extra Kick: Non-adiabatic Effects in Acetaldehyde Photodissociation. AB - The effect of non-adiabatic transitions on branching ratios, kinetic and internal energy distribution of fragments, and reaction mechanisms observed in acetadehyde photodissociation is investigated by non-adiabatic molecular dynamics (NAMD) simulations using time-dependent hybrid density functional theory and Tully surface hopping. Homolytic bond breaking is approximately captured by allowing spin symmetry to break. The NAMD simulations reveal that non-adiabatic transitions selectively enhance the kinetic energy of certain internal degrees of freedom within approximately 50 fs. Branching ratios from NAMD and conventional ''hot'' Born-Oppenheimer molecular dynamics (BOMD) are similar and qualitatively agree with experiment. However, as opposed to the BOMD simulations, NAMD captures the high-energy tail of the experimental kinetic energy distribution. The extra "kick'' of the nuclei in the direction of the non-adiabatic coupling vector results from non-adiabatic transitions close to conical intersections. From a mechanistic perspective, the non-adiabatic effects favor asynchronous over synchronous fragmentation and tend to suppress roaming. PMID- 27704838 TI - Analysis of Differential Efficacy and Affinity of GABAA (alpha1/alpha2) Selective Modulators. AB - Selective modulators of the gamma-amino butyric acid (GABAA) family of receptors have the potential to treat a range of disease states related to cognition, pain, and anxiety. While the development of various alpha subunit-selective modulators is currently underway for the treatment of anxiety disorders, a mechanistic understanding of the correlation between their bioactivity and efficacy, based on ligand-target interactions, is currently still lacking. In order to alleviate this situation, in the current study we have analyzed, using ligand- and structure-based methods, a data set of 5440 GABAA modulators. The Spearman correlation (rho) between binding activity and efficacy of compounds was calculated to be 0.008 and 0.31 against the alpha1 and alpha2 subunits of GABA receptor, respectively; in other words, the compounds had little diversity in structure and bioactivity, but they differed significantly in efficacy. Two compounds were selected as a case study for detailed interaction analysis due to the small difference in their structures and affinities (DeltapKi(comp1_alpha1 - comp2_alpha1) = 0.45 log units, DeltapKi(comp1_alpha2 - comp2_alpha2) = 0 log units) as compared to larger relative efficacies (DeltaRE(comp1_alpha1 - comp2_alpha1) = 1.03, DeltaRE(comp1_alpha2 - comp2_alpha2) = 0.21). Docking analysis suggested that His-101 is involved in a characteristic interaction of the alpha1 receptor with both compounds 1 and 2. Residues such as Phe-77, Thr 142, Asn-60, and Arg-144 of the gamma chain of the alpha1gamma2 complex also showed interactions with heterocyclic rings of both compounds 1 and 2, but these interactions were disturbed in the case of alpha2gamma2 complex docking results. Binding pocket stability analysis based on molecular dynamics identified three substitutions in the loop C region of the alpha2 subunit, namely, G200E, I201T, and V202I, causing a reduction in the flexibility of alpha2 compared to alpha1. These amino acids in alpha2, as compared to alpha1, were also observed to decrease the vibrational and dihedral entropy and to increase the hydrogen bond content in alpha2 in the apo state. However, freezing of both alpha1 and alpha2 was observed in the ligand-bound state, with an increased number of internal hydrogen bonds and increased entropy. Therefore, we hypothesize that the amino acid differences in the loop C region of alpha2 are responsible for conformational changes in the protein structure compared to alpha1, as well as for the binding modes of compounds and hence their functional signaling.

AB - The structure, bonding, and other properties of phases in the carbon-hydrogen system over a range of conditions is of considerable importance to a broad range of scientific problems. However, the phase diagram of the C-H system at high pressures and temperatures is still not known. To search for new low energy hydrocarbon structures, we carried out a systematic structure prediction search for the C-H system from 100-300 GPa. We confirmed several previously predicted structures but found additional stoichiometries that adopt more stable structures. In particular, a C2H4 structure is found that has an indirect band gap and phonon calculations confirm it is dynamically stable over a broad pressure range. We also identify more carbon-rich structures that are energetically favorable. The results are important for understanding carbon hydrogen interactions in high-pressure astrophysical environments, the deep carbon cycle in planetary interiors, as well as resolving controversies for recent experiments on hydrogen-containing samples at megabar pressures using diamond anvil cells. PMID- 27704841 TI - Quest for Inexpensive Hydrogen Isotopic Fractionation: Do We Need 2D Quantum Confining in Porous Materials or Are Rough Surfaces Enough? The Case of Ammonia Nanoclusters. AB - We study the adsorption energetics and quantum properties of the molecular hydrogen isotopes H2, D2, and T2 onto the surface of rigid ammonia nanoclusters with quantum simulations and accurate model potential energy surfaces (PES). A highly efficient diffusion Monte Carlo (DMC) algorithm for rigid rotors allowed us to accurately define zero-point adsorption energies for the three isotopes, as well as the degree of translational and rotational delocalization that each affords on the surface. From the data emerges that the quantum adsorption energy (Eads) of T2 can be up to twice the one of H2 at 0 K, suggesting the possibility of exploiting some form of solid ammonia to selectivity separate hydrogen isotopes at low temperatures (?20 K). This is discussed by focusing on the structural motif that may be more effective for the task. The analysis of the contributions to Eads, however, surprisingly indicates that the average kinetic energy (Ekin) and rotation energy (Erotkin) of T2 can also be, respectively, 2 times and 20 times higher than those of H2; this finding markedly deviates from what is predicted for hydrogen molecules inside carbon nanotubes (CNT) or metallic-organic frameworks (MOF), where Ekin and Erotkin is higher for H2 due to the unavoidable effects of confinement and hindrance to its rotational motion. The rationale for these differences is provided by the geometrical distributions for the rigid rotors, which reveal an increasingly stronger coupling between rotational and translational degrees of freedom upon increasing the isotopic mass. This effect has never been observed before on adsorbing surfaces (e.g., graphite) and is induced by a strongly anisotropic and anharmonic bowl-like potential experienced by the rotors.

AB - Rheumatoid arthritis is a progressive, highly debilitating disease where early diagnosis, enabling rapid clinical intervention, would provide obvious benefits to patients, healthcare systems, and society. Novel biomarkers that enable noninvasive early diagnosis of the onset and progression of the disease provide one route to achieving this goal. Here a metabolic profiling method has been applied to investigate disease development in the Tg197 arthritis mouse model. Hind limb extract profiling demonstrated clear differences in metabolic phenotypes between control (wild type) and Tg197 transgenic mice and highlighted raised concentrations of itaconic acid as a potential marker of the disease. These changes in itaconic acid concentrations were moderated or indeed reversed when the Tg197 mice were treated with the anti-hTNF biologic infliximab (10 mg/kg twice weekly for 6 weeks). Further in vitro studies on synovial fibroblasts obtained from healthy wild-type, arthritic Tg197, and infliximab-treated Tg197 transgenic mice confirmed the association of itaconic acid with rheumatoid arthritis and disease-moderating drug effects. Preliminary indications of the potential value of itaconic acid as a translational biomarker were obtained when studies on K4IM human fibroblasts treated with hTNF showed an increase in the concentrations of this metabolite.

AB - Light Harvesting Complex II (LHCII) serves a central role in light harvesting for oxygenic photosynthesis, and is arguably the most important photosynthetic antenna complex. In this work, we present two-dimensional electronic-vibrational (2DEV) spectra of LHCII isolated from spinach, demonstrating the possibility of using this technique to track the transfer of electronic excitation energy between specific pigments within the complex. We assign the spectral bands via comparison with the 2DEV spectra of the isolated chromophores, chlorophyll a and b, and present evidence that excitation energy between the pigments of the complex are observed in these spectra. Finally, we analyze the essential components of the 2DEV spectra using singular value decomposition, which makes it possible to reveal the relaxation pathways within this complex.

AB - We compare the ability of four popular hybrid density functionals (B3LYP, B3PW91, HSE, and PBE0) for predicting band gaps of semiconductors and insulators over a large benchmark set using a consistent methodology. We observe no significant statistical difference in their overall performance although the screened hybrid HSE is more accurate for typical semiconductors. HSE can improve its accuracy for large large band gap materials --without affecting that of semiconductors-- by including a larger portion of Hartree--Fock exchange in its short range. Given that screened hybrids are computationally much less expensive than their global counterparts, we conclude that they are a better option for the black box prediction of band gaps.

AB - The internal structure of hollow AgAu nanorods created by partial galvanic replacement was manipulated reversibly, and its effect on optical properties was mapped with nanometer resolution. Using the electron beam in a scanning transmission electron microscope to create solvated electrons and reactive radicals in an encapsulated solution-filled cavity in the nanorods, Ag ions were reduced nearby the electron beam, reshaping the core of the nanoparticles without affecting the external shape. The changes in plasmon-induced near-field properties were then mapped with electron energy-loss spectroscopy without disturbing the internal structure, and the results are supported by finite difference time-domain calculations. This reversible shape and near-field control in a hollow nanoparticle actuated by an external stimulus introduces possibilities for applications in reprogrammable sensors, responsive materials, and optical memory units. Moreover, the liquid-filled nanorod cavity offers new opportunities for in situ microscopy of chemical reactions. PMID- 27704846 TI - Pore Environment Effects on Catalytic Cyclohexane Oxidation in Expanded Fe2(dobdc) Analogues. AB - Metal-organic frameworks are a new class of heterogeneous catalysts in which molecular-level control over both the immediate and long-range chemical environment surrounding a catalytic center can be readily achieved. Here, the oxidation of cyclohexane to cyclohexanol and cyclohexanone is used as a model reaction to investigate the effect of a hydrophobic pore environment on product selectivity and catalyst stability in a series of iron-based frameworks. Specifically, expanded analogues of Fe2(dobdc) (dobdc4- = 2,5-dioxido-1,4 benzenedicarboxylate) were synthesized and evaluated, including the biphenyl derivative Fe2(dobpdc) (H4dobpdc = 4,4'-dihydroxy-[1,1'-biphenyl]-3,3' dicarboxylic acid), the terphenyl derivative Fe2(dotpdc) (H4dotpdc = 4,4" dihydroxy-[1,1':4',1"-terphenyl]-3,3"-dicarboxylic acid), and three modified terphenyl derivatives in which the central ring is replaced with tetrafluoro-, tetramethyl-, or di-tert-butylaryl groups. Within these five materials, a remarkable 3-fold enhancement of the alcohol:ketone (A:K) ratio and an order of magnitude increase in turnover number are achieved by simply altering the framework pore diameter and installing nonpolar functional groups near the iron site. Mossbauer spectroscopy, kinetic isotope effect, and gas adsorption measurements reveal that variations in the A:K selectivities arise from differences in the cyclohexane adsorption enthalpies of these frameworks, which become more favorable as the number of hydrophobic residues and thus van der Waals interactions increase. PMID- 27704847 TI - Reconfigurable van der Waals Heterostructured Devices with Metal-Insulator Transition. AB - Atomically thin two-dimensional (2D) materials range from semimetallic graphene to insulating hexagonal boron nitride to semiconducting transition-metal dichalcogenides. Recently, metal-insulator-semiconductor field effect transistors built from these 2D elements were studied for flexible and transparent electronics. However, to induce ambipolar characteristics for alternative power efficient circuitry, ion-gel gating is often employed for high capacitive coupling, limiting stable operation at ambient conditions. Here, we report reconfigurable MoTe2 optoelectronic transistors with all 2D components, where the device can be reconfigured by both drain and gate voltages. Eight different configurations for each fixed voltage are spatially resolved by scanning photocurrent microscopy. In addition, metal-insulator transitions are observed in both electron and hole carriers under 2 V due to strong Coulomb interaction in the system. Furthermore, the vertical tunneling photocurrent through multiple van der Waals layers between the gate and source contacts is measured. Our reconfigurable devices offer potential building blocks for system-on-a-chip optoelectronics. PMID- 27704848 TI - Nontargeted LC-MS Metabolomics Approach for Metabolic Profiling of Plasma and Urine from Pigs Fed Branched Chain Amino Acids for Maximum Growth Performance. AB - The metabolic response in plasma and urine of pigs when feeding an optimum level of branched chain amino acids (BCAAs) for best growth performance is unknown. The objective of the current study was to identify the metabolic phenotype associated with the BCAAs intake level that could be linked to the animal growth performance. Three dose-response studies were carried out to collect blood and urine samples from pigs fed increasing levels of Ile, Val, or Leu followed by a nontargeted LC-MS approach to characterize the metabolic profile of biofluids when dietary BCAAs are optimum for animal growth. Results showed that concentrations of plasma hypoxanthine and tyrosine (Tyr) were higher while concentrations of glycocholic acid, tauroursodeoxycholic acid, and taurocholic acid were lower when the dietary Ile was optimum. Plasma 3-methyl-2-oxovaleric acid and creatine were lower when dietary Leu was optimum. The optimum dietary Leu resulted in increased urinary excretion of ascorbic acid and choline and relatively decreased excretion of 2-aminoadipic acid, acetyl-dl-valine, Ile, 2 methylbutyrylglycine, and Tyr. In conclusion, plasma glycocholic acid and taurocholic acid were discriminating metabolites to the optimum dietary Ile. The optimum dietary Leu was associated with reduced plasma creatine and urinary 2 aminoadipic acid and elevated urinary excretion of ascorbic acid and choline. The optimum dietary Val had a less pronounced metabolic response reflected in plasma or urine than other BCAA. PMID- 27704849 TI - Copper Coordination Features of Human Islet Amyloid Polypeptide: The Type 2 Diabetes Peptide. AB - Human islet amyloid polypeptide (hIAPP) is the major component of amyloid deposits found in pancreatic beta-cells of patients with type 2 diabetes (T2D). Copper ions have an inhibitory effect on the amyloid aggregation of hIAPP, and they may play a role in the etiology of T2D. However, deeper knowledge of the structural details of the copper-hIAPP interaction is required to understand the molecular mechanisms involved. Here, we performed a spectroscopic study of Cu(II) binding to hIAPP and several variants, using electron paramagnetic resonance (EPR), nuclear magnetic resonance (NMR), electronic absorption, and circular dichroism (CD) in the UV-vis region in combination with Born-Oppenheimer molecular dynamics (BOMD) and density functional theory geometry optimizations. We find that Cu(II) binds to the imidazole N1 of His18, the deprotonated amides of Ser19 and Ser20, and an oxygen-based ligand provided by Ser20, either via its hydroxyl group or its backbone carbonyl, while Asn22 might also play a role as an axial ligand. Ser20 plays a crucial role in stabilizing Cu(II) coordination toward the C-terminal, providing a potential link between the S20G mutation associated with early onset of T2D, its impact in Cu binding properties, and hIAPP amyloid aggregation. Our study defines the nature of the coordination environment in the Cu(II)-hIAPP complex, revealing that the amino acid residues involved in metal ion binding are also key residues for the formation of beta sheet structures and amyloid fibrils. Cu(II) binding to hIAPP may lead to the coexistence of more than one coordination mode, which in turn could favor different sets of Cu-induced conformational ensembles. Cu-induced hIAPP conformers would display a higher energetic barrier to form amyloid fibrils, hence explaining the inhibitory effect of Cu ions in hIAPP aggregation. Overall, this study provides further structural insights into the bioinorganic chemistry of T2D.

AB - Dearomatization provides numerous possibilities for the development of new transformative modes of aromatic compounds. A conceptually novel metal-free multicomponent domino reaction of the dearomatized products of 2-alkynylanilines is developed. The reaction involves the secondary amine-mediated transimination with alpha-amino nitriles and subsequent aromatization-triggered cascade rearrangement, nucleophilic cyclization, and retro-Strecker reaction. This process provided a new practical method for the rapid synthesis of polyfunctionalized 4-aminoquinolines from readily available starting materials. PMID- 27704850 TI - Electromechanical Properties and Spontaneous Response of the Current in InAsP Nanowires. AB - The electromechanical properties of ternary InAsP nanowires (NWs) were investigated by applying a uniaxial tensile strain in a transmission electron microscope (TEM). The electromechanical properties in our examined InAsP NWs were governed by the piezoresistive effect. We found that the electronic transport of the InAsP NWs is dominated by space-charge-limited transport, with a I infinity V2 relation. Upon increasing the tensile strain, the electrical current in the NWs increases linearly, and the piezoresistance gradually decreases nonlinearly. By analyzing the space-charge-limited I-V curves, we show that the electromechanical response is due to a mobility that increases with strain. Finally, we use dynamical measurements to establish an upper limit on the time scale for the electromechanical response.

AB - Despite their tremendous synthetic and pharmaceutical utility, primary azaaromatic amines remain elusive for access based on a generally applicable C-H functionalization strategy. An oxadiazolone-enabled approach is reported for convenient entry into N-unsubstituted 1-aminoisoquinolines through Co(III) catalyzed redox-neutral, step-, atom-, and purification-economic C-H functionalization with alkynes.

AB - A cross-coupling strategy for the preparation of novel sulfoximines via preformed sulfoximidoyl-containing building blocks has been developed. It allows obtaining a wide range of products in good yields under mild reaction conditions, and it can be applied in late-stage functionalizations, as demonstrated by the synthesis of a sulfoximine-based analogue of a recently reported potent valosine-containing protein inhibitor. PMID- 27704854 TI - Synthesis of the Azepinobisindole Alkaloid Iheyamine A Enabled by a Cross-Mannich Reaction. AB - The total synthesis of the azepinobisindole alkaloid iheyamine A is described. The successful strategy hinged on an intermolecular cross-Mannich reaction between 5-methoxy-3-acetoxyindole and a protected tryptamine to access an unsymmetrical 2,2'-bisindole, which was subsequently converted into iheyamine A via a deep-blue 3-indolone intermediate. VT 1H NMR infers that iheyamine A exists as a mixture of tautomers that undergo intermediate chemical exchange on the NMR time scale. The intermolecular cross-Mannich reaction described herein is a viable alternative to metal-catalyzed cross-coupling strategies commonly employed to access 2,2'-bisindoles. PMID- 27704855 TI - Electrostatically Driven Nanoballoon Actuator. AB - We demonstrate an inflatable nanoballoon actuator based on geometrical transitions between the inflated (cylindrical) and collapsed (flattened) forms of a carbon nanotube. In situ transmission electron microscopy experiments employing a nanoelectromechanical manipulator show that a collapsed carbon nanotube can be reinflated by electrically charging the nanotube, thus realizing an electrostatically driven nanoballoon actuator. We find that the tube actuator can be reliably cycled with only modest control voltages (few volts) with no apparent wear or fatigue. A complementary theoretical analysis identifies critical parameters for nanotube nanoballoon actuation.

Vicinal difluorination and dichlorolation products have also been achieved via this reaction. PMID- 27704857 TI - Precise Perforation and Scalable Production of Si Particles from Low-Grade Sources for High-Performance Lithium Ion Battery Anodes. AB - Alloy anodes, particularly silicon, have been intensively pursued as one of the most promising anode materials for the next generation lithium-ion battery primarily because of high specific capacity (>4000 mAh/g) and elemental abundance. In the past decade, various nanostructures with porosity or void space designs have been demonstrated to be effective to accommodate large volume expansion (~300%) and to provide stable solid electrolyte interphase (SEI) during electrochemical cycling. However, how to produce these building blocks with precise morphology control at large scale and low cost remains a challenge. In addition, most of nanostructured silicon suffers from poor Coulombic efficiency due to a large surface area and Li ion trapping at the surface coating. Here we demonstrate a unique nanoperforation process, combining modified ball milling, annealing, and acid treating, to produce porous Si with precise and continuous porosity control (from 17% to 70%), directly from low cost metallurgical silicon source (99% purity, ~ $1/kg). The produced porous Si coated with graphene by simple ball milling can deliver a reversible specific capacity of 1250 mAh/g over 1000 cycles at the rate of 1C, with Coulombic efficiency of first cycle over 89.5%. The porous networks also provide efficient ion and electron pathways and therefore enable excellent rate performance of 880 mAh/g at the rate of 5C. Being able to produce particles with precise porosity control through scalable processes from low-grade materials, it is expected that this nanoperforation may play a role in the next generation lithium ion battery anodes, as well as many other potential applications such as optoelectronics and thermoelectrics.

AB - A simple and efficient metal-free sulfenylation/cyclization of aryl alkynoates has been developed, obtaining various 3-sulfenylated coumarins in moderate to excellent yields. In the presence of BF3.Et2O, the stable and readily accessible N-sulfanylsuccinimides were employed as electrophiles to induce the 6-endo-dig electrophilic cyclization of alkynoates. The reaction using substrates bearing a methoxy group on the phenoxy ring proceeded in an exclusively distinct pathway via either ipso sulfenylcyclization or sulfenylation of the phenoxy ring depending on the different locations of the methoxy substituent. The resulting 3 sulfenylated coumarins can be readily transformed to 3-sulfinylated or 3 sulfonylated coumarins under different oxidation conditions.

This concise method allows for the rapid formation of a number of benzo[a]carbazoles in high yields, exhibiting good functional group tolerance and scalability.

PMID- 27704861 TI - Probing Residue-Specific Water-Protein Interactions in Oriented Lipid Membranes via Solid-State NMR Spectroscopy. AB - Water plays a central role in membrane protein folding and function. It not only catalyzes lipid membrane self-assembly, but it is also affects the structural integrity and conformational dynamics of membrane proteins. Magic angle spinning (MAS) solid-state NMR is the technique of choice for measuring water accessibility of membrane proteins in a site-specific manner, providing a ruler for membrane protein topology and insertion within lipid bilayers. However, sensitivity and resolution of membrane protein samples for MAS experiments is often dictated by hydration levels, which affect membrane proteins structural dynamics. Oriented sample solid-state NMR (OS-ssNMR) is a complementary technique to determine both structure and topology of membrane proteins in liquid crystalline bilayers. Recent advancements in OS-ssNMR involve the use of oriented bicellar phases that have improved both sensitivity and resolution. Importantly, for bicelles formation and orientation, lipid bilayers must be well organized and hydrated, resulting in the protein's topology being similar to that found in native membranes. Under these conditions, the NMR resonances become relatively narrow, enabling a better separation of 1H-15N dipolar couplings and anisotropic 15N chemical shifts with separated local field (SLF) experiments. Here we report a residue-specific water accessibility experiment for a small membrane protein, sarcolipin, embedded in oriented lipid bicelles as probed by new water-edited SLF experiments (WE-SLF). We show that sarcolipin's residues belonging to the juxtamembrane region are more exposed to the water-lipid interface than the corresponding membrane-embedded residues. The information that can be obtained from the WE-SLF experiments can be interpreted using a simple model based on spin diffusion theory and offers a complete characterization of membrane proteins in realistic membrane bilayer systems. PMID- 27704862 TI - Chloride Selective Macrocyclic Bisurea Derivatives with 2,2'-Binaphthalene Moieties as Spacers. AB - A cyclic bisurea derivative 2a has been successfully prepared from the corresponding diamine and diisocyanate in the presence of tetrabutylammonium chloride as a template. A more soluble cyclic bisurea 2b has also been prepared by introduction of sterically bulky tert-butyl groups. X-ray crystal analyses of [2a.Cl]- and [2b.Cl]- revealed that overall structure was saddle like and the chloride anion was located in the center of the cavity. The bound chloride anion was hydrogen bonded by four N-H of urea groups and weakly hydrogen bonded by four 1-C-H of naphthyl groups, respectively. After removal of the bound chloride anions of [2b.Cl]- with silver nitrate, two different X-ray crystals of free 2b were obtained; one was intermolecular hydrogen bonded shrunken structure and the other was extended structure. Receptor 2b showed large binding ability for Cl-, however, the selectivity for Cl- against basic anions, such as AcO- and F-, has been insufficient. In aqueous MeCN, the association constant of 2b for Cl- was reduced but still large, and the selectivity for hydrophobic Cl- was greatly improved. In this solvent, 2b also selectively recognized alkaline metal chloride salts. Therefore, cyclic bisurea 2b is highly selective and effective Cl- selective receptor. PMID- 27704863 TI - Microwave Photodetection in an Ultraclean Suspended Bilayer Graphene p-n Junction. AB - We explore the potential of bilayer graphene as a cryogenic microwave photodetector by studying the microwave absorption in fully suspended clean bilayer graphene p-n junctions in the frequency range of 1-5 GHz at a temperature of 8 K. We observe a distinct photocurrent signal if the device is gated into the p-n regime, while there is almost no signal for unipolar doping in either the n-n or p-p regimes. Most surprisingly, the photocurrent strongly peaks when one side of the junction is gated to the Dirac point (charge-neutrality point CNP), while the other remains in a highly doped state. This is different to previous results where optical radiation was used. We propose a new mechanism based on the phototermal effect explaining the large signal. It requires contact doping and a distinctly different transport mechanism on both sides: one side of graphene is ballistic and the other diffusive. By engineering partially diffusive and partially ballistic devices, the photocurrent can drastically be enhanced. PMID- 27704864 TI - Scalable Regioselective Synthesis of Rhodamine Dyes.

PMID- 27704865 TI - Effectiveness of Ayurvedic Massage (Sahacharadi Taila) in Patients with Chronic Low Back Pain: A Randomized Controlled Trial. AB - OBJECTIVES: Ayurveda is one of the oldest comprehensive healthcare systems worldwide. Ayurvedic massage and physical therapy are frequently used to treat patients with chronic pain syndromes and disorders of the musculoskeletal system. This study aimed to evaluate the effectiveness of Ayurvedic massage in nonspecific chronic low back pain by means of a randomized clinical trial. DESIGN: Sixty-four patients (mean age, 54.8 years; 49 women and 15 men) with chronic low back pain who scored >40 mm on a 100-mm visual analogue scale (VAS) were randomly assigned to a 2-week massage group with 6 hours of Ayurvedic massage and external treatment (n = 32) or to a 2-week local thermal therapy group (n = 32). The study observation period was 4 weeks, consisting of a 2-week intervention phase followed by a 2-week follow-up phase. OUTCOME MEASURES: Primary outcome measure was the change of mean pain (VAS) from baseline to week 4. Secondary outcomes included pain-related bothersomeness, the Roland Disability Questionnaire, quality of life (Medical Outcomes Study 36-Item Short Form), the Hanover Functional Ability Questionnaire for measuring back pain-related disability, and psychological outcomes. Outcomes were assessed at baseline and after 2 and 4 weeks. RESULTS: Mean back pain (primary outcome) at week 2 was significantly reduced from 53.4 +/- 18.5 to 21.6 +/- 18.2 in the massage group and from 55.3 +/- 12.9 to 41.8 +/- 19.8 in the standard thermal therapy group (mean group difference, -18.7; 95% confidence interval, -28.7 to -8.7; p < 0.001). While beneficial effects on pain-related bothersomeness and psychological well-being were also apparent, the Ayurvedic intervention did not improve function or disability in the short-term observation period. Both programs were safe and well tolerated. CONCLUSIONS: Ayurvedic external treatment is effective for pain-relief in chronic low back pain in the short term. Further studies with longer observation periods are needed to evaluate the long-term effects of the Ayurvedic external treatment approach on function and disability.

Most studied models assumed a single copy per gene. However, in reality, duplicated genes are common, most notably in cancer. In this study, we make a step toward handling duplicated genes by considering a model that allows the atomic operations of cut, join, and whole chromosome duplication. Given two linear genomes, [Formula: see text] with one copy per gene and [Formula: see text] with two copies per gene, we give a linear time algorithm for computing a shortest sequence of operations transforming [Formula: see text] into [Formula: see text] such that all intermediate genomes are linear. We also show that computing an optimal sequence with fewest duplications is NP-hard. PMID- 27704868 TI - Biomarkers and the sample matrix: challenges and opportunities.

AB - Caffeine (CAF) blunts estimated ratings of perceived exertion (RPE) but the effects on RPE production are unclear. This study examined effects of acute caffeine ingestion during treadmill exercise where participants exercised at prescribed RPE 4 and 7. Recreational runners (maximal oxygen consumption = 51.4 +/- 9.8 mL.kg-1.min-1) (n = 16) completed a maximal treadmill test followed by trials where they selected treadmill velocity (VEL) (1% grade) to produce RPE 4 and RPE 7 (10 min each). RPE production trials followed CAF (6 mg.kg-1) or placebo (PLA) (counterbalanced) ingestion. Participants were blinded to treadmill VEL but the Omni RPE scale was in full view. Repeated-measures ANOVA showed a main effect (trial) for VEL (CAF ~5 m.min-1 faster) for RPE 4 (p = 0.07) and RPE 7 (p = 0.03). Mean heart rate and oxygen consumption responses were consistently higher for CAF but failed to reach statistical significance. Individual responses to CAF were labeled positive using a criterion of 13.4 m.min-1 faster for CAF (vs. PLA). Ten of 32 trials (31%) were positive responses. In these, systematic increases were observed for heart rate (~12 beats.min-1) and oxygen consumption (~5.7 mL.kg-1.min-1). Blunted/stable respiratory exchange ratio values at higher VEL for positive responders suggest increased free fatty acid reliance during CAF. In conlusion, mean results show a mild effect of CAF during RPE production. However, individual responses more clearly indicate whether a true effect is possible. Trainers and individuals should consider individual responses to ensure effectively intensity regulation. PMID- 27704870 TI - Commercial biomarker assays: friend and foe. AB - AIM: Commercial kits can provide a convenient solution for measuring circulating biomarkers to support drug development. However, their suitability should be assessed in the disease matrix of interest. METHODOLOGY: Twelve biomarkers were evaluated in samples from patients with rheumatoid arthritis. We used immunoassay kits from five vendors on three multiplexed platforms. Kit suitability was evaluated on the basis of detectability and prespecified performance acceptance criteria. RESULTS: Assays had varying levels of sensitivity and susceptibility to interference by matrix components. Only a few assays in the multiplexed kits were found to be suitable. In general, kits for analytes that passed our assay criteria showed good correlation between vendors. CONCLUSION: The data from this study demonstrate that the majority of assays on multiplexed kits evaluated either lacked sensitivity and/or had poor performance, which diminishes the utility of the multiplexing approach. PMID- 27704871 TI - The Association of Prenatal Tocolysis and Breastfeeding Duration. AB - BACKGROUND: To date there are no clinical studies analyzing potential effects of tocolytics on breastfeeding duration in humans. OBJECTIVES: The purpose of this study was to evaluate the association between beta 2 agonists prescribed for tocolysis during pregnancy and breastfeeding duration. METHODS: We conducted a cross-sectional questionnaire study of 114 mothers and filled in the questionnaire developed to directly address the goals of the study. RESULTS: There was a statistically significant difference between breastfeeding duration of mothers who were on tocolytics during pregnancy versus those who were not prescribed tocolytics (9.5 +/- 5.7 months versus 4.5 +/- 2.1 months) p < 0.001. In addition, hypogalactia was statistically significantly more prevalent in mothers with positive history versus mothers with negative history of tocolytic usage p < 0.001. CONCLUSION: The results of our study indicate that tocolytic treatment in pregnancy is associated with shorter breastfeeding duration and hypogalactia. PMID- 27704872 TI - MR imaging of the temporomandibular joint: comparison between acquisitions at 7.0 T using dielectric pads and 3.0 T. AB - OBJECTIVES: To qualitatively and quantitatively compare MRI of the temporomandibular joint (TMJ) at 7.0 T using high-permittivity dielectric pads and 3.0 T using a clinical high-resolution protocol. METHODS: Institutional review board-approved study with written informed consent. 12 asymptomatic volunteers were imaged at 7.0 and 3.0 T using 32-channel head coils. High permittivity dielectric pads consisting of barium titanate in deuterated suspension were used for imaging at 7.0 T. Imaging protocol consisted of oblique sagittal proton density weighted turbo spin echo sequences. For quantitative analysis, pixelwise signal-to-noise ratio maps of the TMJ were calculated. For qualitative analysis, images were evaluated by two independent readers using 5 point Likert scales. Quantitative and qualitative results were compared using t tests and Wilcoxon signed-rank tests, respectively. RESULTS: TMJ imaging at 7.0 T using high-permittivity dielectric pads was feasible in all volunteers. Quantitative analysis showed similar signal-to-noise ratio for both field strengths (mean +/- SD; 7.0 T, 13.02 +/- 3.92; 3.0 T, 14.02 +/- 3.41; two-sample t-tests, p = 0.188). At 7.0 T, qualitative analysis yielded better visibility of all anatomical subregions of the temporomandibular disc (anterior band, intermediate zone and posterior band) than 3.0 T (Wilcoxon signed-rank tests, p < 0.05, corrected for multiple comparisons). CONCLUSIONS: MRI of the TMJ at 7.0 T using high-permittivity dielectric pads yields superior visibility of the temporomandibular disc compared with 3.0 T.

AB - The purpose of this study was to investigate the therapeutic effects of hyperoside (Hyp) on glomerulosclerosis in diabetic nephropathy and its underlying mechanisms. Blood glucose, kidney mass, and renal function of mice were measured. Renal morphology was observed using hematoxylin and eosin, periodic acid - Schiff's, and Masson's trichrome stain. Fibronectin (FN) and collagen IV (COL IV) in kidney were determined by Western blot and immunohistochemical studies. Matrix metalloproteinases (MMP)-2 and -9 and tissue inhibitors of metalloproteinase (TIMP)-1 in renal tissues were detected on both the mRNA and protein levels. miRNA expression and artificial alterations by miRNA agomir transfection were evaluated to investigate the protective mechanism of Hyp in mesangial cells. Hyp effectively improved renal function and physiologic features of db/db mice. Hyp also ameliorated glomerulosclerosis by suppressing FN, COL IV, and TIMP-1 expressions and promoting MMP-9 and MMP-2 expressions. The change in MMP-9 mRNA expression was inconsistent with that in protein levels in kidney, indicating that there was a post-transcriptional regulation. Further exploration in vitro showed that miR-21 was downregulated by Hyp, increasing expression of its target, MMP-9. These results suggest that Hyp can ameliorate glomerulosclerosis in diabetic nephropathy by downregulating miR-21 to increase expression of its target, MMP-9. PMID- 27704875 TI - Physiology-Invariant Meal Detection for Type 1 Diabetes. AB - BACKGROUND: Fully automated artificial pancreas systems require meal detectors to supplement blood glucose level regulation, where false meal detections can cause unnecessary insulin delivery with potentially fatal consequences, and missed detections may cause the patient to experience extreme hyperglycemia. Most existing meal detectors monitor various measures of glucose rate-of-change to detect meals where varying physiology and meal content complicate balancing detector sensitivity versus specificity. METHODS: We developed a novel meal detector based on a minimal glucose-insulin metabolism model and show that the detector is, by design, invariant to patient-specific physiological parameters in the minimal model. Our physiological parameter-invariant (PAIN) detector achieves a near-constant false alarm rate across all individuals and is evaluated against three other major existing meal detectors on a clinical type 1 diabetes data set. RESULTS: In the clinical evaluation, the PAIN-based detector achieves an 86.9% sensitivity for an average false alarm rate of two alarms per day. In addition, for all false alarm rates, the PAIN-based detector performance is significantly better than three other existing meal detectors. In addition, the evaluation results show that the PAIN-based detector uniquely (as compared with the other meal detectors) has low variance in detection and false alarm rates across all patients, without patient-specific personalization. CONCLUSIONS: The PAIN-based meal detector has demonstrated better detection performance than existing meal detectors, and it has the unique strength of achieving a consistent performance across a population with varying physiology without any individual-level parameter tuning or training. PMID- 27704874 TI - The Effect of Age on the Prevalence of Obesity among US Youth with Autism Spectrum Disorder. AB - BACKGROUND: We sought to assess the association between age and the prevalence of obesity among children with and without autism spectrum disorder (ASD) in the 2011-2012 National Survey of Children's Health. METHODS: Analyses were restricted to 43,777 children, ages 10-17, with valid measures of parent-reported weight, height, and ASD status. Exploratory analyses describe the impact of sex, race/ethnicity, and household income on the relationship between age and obesity in ASD. RESULTS: Although the overall prevalence of obesity among children with ASD was significantly (p < 0.001) higher than among children without ASD (23.1% vs. 14.1%, 95% confidence interval for difference 3.6 to 14.4), child age significantly (p = 0.035) modified this difference. In a multivariable logistic regression analysis, adjusted for sex, race/ethnicity, and household income, the odds of obesity among children with ASD compared with children without ASD increased monotonically from ages 10 to 17 years. This pattern arose due to a consistently high prevalence of obesity among children with ASD and a decline in prevalence with advancing age among children without ASD. These findings were replicated using a propensity score analysis. Exploratory analyses suggested that the age-related change in obesity disparity between children with and without ASD may be further modified by sex, race/ethnicity, and household income. CONCLUSIONS: The patterns of prevalence observed with increasing age among children with and without ASD were unexpected. A better understanding of the etiological and maintenance factors for obesity in youth with ASD is needed to develop interventions tailored to the specific needs of these children.

PMID- 27704876 TI - CD4+Foxp3-IL-10+ Tr1 Cells Promote Relapse of Diffuse Large B Cell Lymphoma by Enhancing the Survival of Malignant B Cells and Suppressing Antitumor T Cell Immunity. AB - Diffuse large B cell lymphoma (DLBCL) is a common B cell malignancy. Complete remission can be achieved in most patients by conventional treatment with rituximab and chemotherapy. However, a subset of remission individuals will develop a relapsed disease for obscure reasons. CD4+Foxp3-IL-10+ cell (Tr1) is a novel cell subtype with the capacity to suppress pro-inflammatory responses, but has not been extensively studied in most tumors. In this study, we investigated the potential role of Tr1 cells in DLBCL. We found that compared to that in healthy controls, the frequency of Tr1 cells was significantly increased in DLBCL patients, even during complete remission. Further study showed that these Tr1 cells were enriched in the CD25low/-Foxp3-CD49b+LAG-3+ fraction and could be developed in vitro from naive CD45RA+ CD4+ T cells. To examine the effect of Tr1 upregulation, we cocultured the enriched in vitro-induced Tr1 cells (iTr1) with autologous primary DLBCL cells and CD3+ T cells and found that iTr1 cells both enhanced the survival of CD20+ DLBCL tumor cells and suppressed the antitumor response of CD3+ T cells through the production of IL-10. Furthermore, the frequency of CD4+Foxp3-IL-10+ Tr1 cells in DLBCL patients during complete remission is directly associated with the risk of relapse. Together, these results suggested that Tr1 cells contributed to tumor cell maintenance and may serve as a prognostic marker and therapeutic target. PMID- 27704880 TI - Message in a bottle.

PMID- 27704894 TI - Associations of IGFBP3 Gene Polymorphism and Gene Expression with the Risk of Osteonecrosis of the Femoral Head in a Han Population in Northern China. AB - The critical roles of IGFBP3 in regulating the osteogenic and adipogenic differentiation of bone marrow mesenchymal stem cells strongly indicate its potential effects on the pathogenesis of osteonecrosis of the femoral head (ONFH). In this study, we investigated the association of IGFBP3 gene polymorphism and its protein expression with the development of ONFH to further explore its molecular pathogenesis. Ligase detection reactions and enzyme-linked immunosorbent assay were used to detect the polymorphisms of rs2453839[C/T] and rs3110697[A/G] and the serum protein expression of IGFBP3 gene in 182 cases and 179 controls, respectively. The serum lipids level was also measured by automatic biochemistry analyzer. The results revealed that the recessive model of rs3110697 and the dominant model of rs2453839 were significantly associated with the increased risk of ONFH (p = 0.048, p = 0.047, respectively). The genotypes of rs2453839 were also significantly related to the clinical stages of ONFH (p = 0.017). More importantly, the serum protein expression of IGFBP3 and insulin-like growth factor 1 (IGF1) in the ONFH group were statistically increased compared with the control group (p = 0.044, p = 0.007). The serum triglyceride and low density lipoprotein cholesterol level in the ONFH group were significantly higher than the control group (p = 0.01, p = 0.005, respectively), but the serum high density lipoprotein cholesterol level of the ONFH group was dramatically lower than the control group (p = 0.0001). Our results showed that both the gene polymorphisms of IGFBP3 and the abnormal protein expression of serum IGFBP3 and IGF1 closely associated with the development of ONFH.

PMID- 27704908 TI - Effect of exercise intensity and mode on acute appetite control in men and women. AB - The aim of this study was to compare the effects of exercise intensity on appetite control: relative energy intake (energy intake minus the energy expenditure of exercise; REI), hunger scores, and appetite-regulating hormones in men and women. Eleven men and 9 women were submitted to 4 experimental sessions: high-intensity intermittent all-out exercise (HIIE-A) for 60 * 8 s interspersed by 12 s of passive recovery; high-intensity intermittent exercise (HIIE) at 100% of maximal load attained in incremental test; steady-state exercise at 60% of maximal load, matched by work done; and a control session. Exercise was performed 1.5 h after a standardized breakfast, and an ad libitum lunch was offered 4 h after breakfast. Blood concentration of insulin, cortisol, acylated ghrelin, peptideYY3-36, glucose, and hunger scores were measured when fasting, and at 1.5, 2, 3.25, and 4 h of experiment. REI was lower in all exercises than in the control, without differences between exercises and sex showing no compensation in energy intake because of any exercise; the hunger scores were lower only in the exercises performed at higher intensity (HIIE and HIIE-A) compared with the control. The area under the curve of acylated ghrelin was lower in the HIIE-A when compared with the control. PeptideYY3-36 was higher in men than women and cortisol higher in women than men independently of the condition. Although high intensity exercises promoted a little more pronounced effects in the direction of suppressing the appetite, no differences were observed in REI, demonstrating that these modifications were not sufficient to affect energy intake. PMID- 27704909 TI - Zika Virus: Pathology From the Pandemic. AB - CONTEXT: -As the number of Zika virus (ZIKV) infections continues to grow, so, too, does the spectrum of recognized clinical disease, in both adult and congenital infections. Defining the tissue pathology associated with the various disease manifestations provides insight into pathogenesis and diagnosis, and potentially future prevention and treatment, of ZIKV infections. OBJECTIVE: -To summarize the syndromes and pathology associated with ZIKV infection, the implications of pathologic findings in the pathogenesis of ZIKV disease, and the use of pathology specimens for diagnosis of ZIKV infection. DATA SOURCES: -The major sources of information for this review were published articles obtained from PubMed and pathologic findings from cases submitted to the Infectious Diseases Pathology Branch at the Centers for Disease Control and Prevention. CONCLUSIONS: -Pathologic findings associated with ZIKV infection are characteristic but not specific. In congenital Zika syndrome, tissue pathology is due to direct viral infection of neural structures, whereas in Guillain-Barre syndrome, pathology is likely due to a postviral, aberrant host-directed immune response. Both fetal and placental pathology specimens are useful for ZIKV diagnosis by molecular and immunohistochemical assays; however, the implications of ZIKV detection in placentas from second- and third-trimester normal live births are unclear, as the potential postnatal effects of late gestational exposure remain to be seen.

PMID- 27704949 TI - Visualizing the Architectures and Interactions of Nuclear Receptors. AB - Nuclear receptors (NRs) are master regulators of broad genetic programs in metazoans. These programs are regulated in part by the small-molecule ligands that bind NRs and modulate their interactions with transcriptional coregulatory factors. X-ray crystallography is now delivering more complete pictures of how the multidomain architectures of NR homo- and heterodimers are physically arranged on their DNA elements and how ligands and coactivator peptides act through these complexes. Complementary studies are also pointing to a variety of novel mechanisms by which NRs access their DNA-response elements within chromatin. Here, we review the new structural advances together with proteomic discoveries that shape our understanding of how NRs form a variety of functional interactions with collaborating factors in chromatin. PMID- 27704948 TI - Bmal1 Is Required for Normal Reproductive Behaviors in Male Mice. AB - Circadian rhythms synchronize physiological processes with the light-dark cycle and are regulated by a hierarchical system initiated in the suprachiasmatic nucleus, a hypothalamic region that receives direct photic input. The suprachiasmatic nucleus then entrains additional oscillators in the periphery. Circadian rhythms are maintained by a molecular transcriptional feedback loop, of which brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 (BMAL1) is a key member. Disruption of circadian rhythms by deletion of the BMAL1 gene (Bmal1 knockout [KO]) induces a variety of disease states, including infertility in males, due to unidentified mechanisms. We find that, despite normal sperm function, Bmal1 KO males fail to mate with receptive females, indicating a behavioral defect. Mating is dependent on pheromone detection, as are several other behaviors. We determined that Bmal1 KO males also fail to display aggression and avoidance of predator scent, despite intact main olfactory function. Moreover, the vomeronasal organ, a specialized pheromone responsive organ, was also functionally intact, as determined by calcium imaging in response to urine pheromone stimulus. However, neural circuit tracing using c FOS activation revealed that, although Bmal1 KO males displayed appropriate activation in the olfactory bulb and accessory olfactory bulb, the bed nucleus of the stria terminalis and the medial preoptic area (areas responsible for integration of copulatory behaviors) failed to activate highly in response to the female scent. This indicates that neural signaling in select behavioral centers is impaired in the absence of BMAL1, likely underlying Bmal1 KO male copulatory defects, demonstrating the importance of the BMAL1 protein in the maintenance of neural circuits that drive pheromone-mediated mating behaviors.

PMID- 27704950 TI - Do Substance P and Neurokinin A Play Important Roles in the Control of LH Secretion in Ewes? AB - There is now general agreement that neurokinin B (NKB) acts via neurokinin-3 receptor (NK3R) to stimulate secretion of GnRH and LH in several species, including rats, mice, sheep, and humans. However, the roles of two other tachykinins, substance P (SP) and neurokinin A, which act primarily via NK1R and NK2R, respectively, are less clear. In rodents, these signaling pathways can stimulate LH release and substitute for NKB signaling; in humans, SP is colocalized with kisspeptin and NKB in the mediobasal hypothalamus. In this study, we examined the possible role of these tachykinins in control of the reproductive axis in sheep. Immunohistochemistry was used to describe the expression of SP and NK1R in the ovine diencephalon and determine whether these proteins are colocalized in kisspeptin or GnRH neurons. SP-containing cell bodies were largely confined to the arcuate nucleus, but NK1R-immunoreactivity was more widespread. However, there was very low coexpression of SP or NK1R in kisspeptin cells and none in GnRH neurons. We next determined the minimal effective dose of these three tachykinins that would stimulate LH secretion when administered into the third ventricle of ovary-intact anestrous sheep. A much lower dose of NKB (0.2 nmol) than of neurokinin A (2 nmol) or SP (10 nmol) consistently stimulated LH secretion. Moreover, the relative potency of these three neuropeptides parallels the relative selectivity of NK3R. Based on these anatomical and pharmacological data, we conclude that NKB-NK3R signaling is the primary pathway for the control of GnRH secretion by tachykinins in ewes.

AB - Codifying a complex treatment intervention into a manual necessarily involves simplifying procedures, possibly resulting in developer and expert adaptations that align with but are not fully consistent with the manualized content. This study evaluated the integrity of an evidence-based treatment to two information sources (i.e., an expert consultant and the treatment manual) within youth community mental health settings. Consultant recommendations were compared with manual-prescribed therapy procedures, which identified instances of agreement between the sources as well as consultant adaptations. To determine clinicians' integrity to each source, clinician-reported therapy procedures were compared with consultant recommendations and manual prescriptions. Participants consisted of 30 clinicians, five consultants, and 78 youths (53% male; M age = 9.73 years, SD = 2.84; 81% Latino). Findings indicated that consultants generally recommended content from the manual but also made frequent adaptations that involved changing the sequence or problem focus of practices and adding additional content. Clinicians followed both information sources in a majority of their sessions when these sources agreed but were more likely to follow only one or neither source when they disagreed. Findings suggest that consultants often make adaptations to the manual and that clinicians are more likely to employ recommendations from the manual and/or consultant when the information sources are in agreement. Although it is as yet unclear whether consultant recommendations are effective when they differ from the prescriptions of the manual, results from this study indicate that information sources that supplement treatment manuals may benefit clinical decision making. PMID- 27704986 TI - Structure-based discovery and binding site analysis of histamine receptor ligands. AB - INTRODUCTION: The application of structure-based drug discovery in histamine receptor projects was previously hampered by the lack of experimental structures. The publication of the first X-ray structure of the histamine H1 receptor has been followed by several successful virtual screens and binding site analysis studies of H1-antihistamines. This structure together with several other recently solved aminergic G-protein coupled receptors (GPCRs) enabled the development of more realistic homology models for H2, H3 and H4 receptors. Areas covered: In this paper, the authors review the development of histamine receptor models and their application in drug discovery. Expert opinion: In the authors' opinion, the application of atomistic histamine receptor models has played a significant role in understanding key ligand-receptor interactions as well as in the discovery of novel chemical starting points. The recently solved H1 receptor structure is a major milestone in structure-based drug discovery; however, our analysis also demonstrates that for building H3 and H4 receptor homology models, other GPCRs may be more suitable as templates. For these receptors, the authors envisage that the development of higher quality homology models will significantly contribute to the discovery and optimization of novel H3 and H4 ligands.

PMID- 27705002 TI - Temperament Distinguishes Persistent/Recurrent from Remitting Anxiety Disorders Across Early Childhood. AB - Up to 20% of preschool-age children meet criteria for anxiety disorders and, for a large subset, anxiety appears to persist throughout early childhood. However, little is known about which factors predict persistence/recurrence of anxiety in young children. Temperament, including behavioral inhibition (BI), negative emotionality (NE), and positive emotionality (PE), predict the onset of anxiety disorders, but to our knowledge no study has examined whether temperament predicts the course of anxiety in young children. From a community sample of 3 year-olds, we identified 89 children (79.8% White, non-Hispanic; 41.6% female) who met criteria for an anxiety disorder and examined whether observed and parent reported BI, NE, and PE at age 3 distinguished children who continued to meet criteria for an anxiety disorder from those who remitted by age 6. Higher levels of BI and lower levels of PE assessed in the laboratory and higher parent reported BI and shyness and lower surgency at age 3 significantly predicted persistence/recurrence of anxiety disorders from age 3 to 6. These data are the first to demonstrate the influence of temperament on the course of anxiety disorders in young children. These findings can enhance assessment and treatment of anxiety by focusing intervention efforts on children who are at risk for persistent or recurring anxiety rather than children who are displaying transient, and possibly developmentally normative, anxiety. PMID- 27705004 TI - CRP/IL-6/IL-10 Single-Nucleotide Polymorphisms Correlate with the Susceptibility and Severity of Community-Acquired Pneumonia. AB - OBJECTIVE: To explore the associations of single-nucleotide polymorphisms (SNPs) of the C-reactive protein (CRP), interleukin 6 (IL-6) and IL-10 genes with susceptibility and severity of community-acquired pneumonia (CAP). MATERIALS AND METHODS: Two hundred seventy-nine CAP patients were selected for the case group and 156 healthy individuals for the control group. Polymerase chain reaction restriction fragment length polymorphism was performed for genotyping of CRP +1059G/C (rs1800947) and +1846C/T (rs1205), IL-6 -597G/A (rs1800797) and -572C/G (rs1800796), and IL-10 -592C/A (rs1800872) and -1082G/A (rs1800896). According to CURB-65 score, the patients were assigned into the severe community-acquired pneumonia (SCAP) and non-SCAP groups. RESULTS: The frequencies of the CRP +1846C/T (rs1205) (CT+TT) genotypes and T allele, the IL-6 -597G/A (rs1800797) (AA+AG) genotypes and A allele, and the IL-10 -592C/A (rs1800872) (CA+AA) genotypes and A allele were higher in the case group than the control group. Furthermore, the frequencies of the CRP +1846C/T (rs1205) (CT+TT) genotypes and T allele, the IL-6 -597G/A (rs1800797) A allele, and the IL-10 -592C/A (rs1800872) (CA+AA) genotypes and A allele were higher in the SCAP group than in the non-SCAP group. CONCLUSION: The CRP +1846C/T (rs1205), IL-6 -597G/A (rs1800797), and IL-10 -592C/A (rs1800872) may be associated with the susceptibility and severity of CAP. PMID- 27705006 TI - Effects of Nintendo WiiTM Training on Occupational Performance, Balance, and Daily Living Activities in Children with Spastic Hemiplegic Cerebral Palsy: A Single-Blind and Randomized Trial. AB - OBJECTIVE: This study aimed at assessing how the addition of Nintendo WiiTM (NW) system to the traditional therapy influences occupational performance, balance, and daily living activities in children with spastic hemiplegic Cerebral Palsy (CP). MATERIALS AND METHODS: The present study is a single-blind and randomized trial involving 24 children aged 6-14 years, classified as level I or II on the Gross Motor Function Classification System. The children were allocated into two groups: an intervention and a control group, and their families participated in the study. The activity performance analysis of the children was undertaken by using the Canadian Occupational Performance Measure (COPM), functional balance was measured with the Pediatric Balance Scale (PBS), and activities of daily living were assessed with Pediatric Evaluation of Disability Inventory (PEDI). Twenty-four children with CP were randomly divided into two groups: intervention (n = 12) and control group (n = 12). All children in both groups continued their traditional physiotherapy program twice a week, 45 minutes per session, whereas the participants in the intervention group, additionally, were trained with NW, two other days of the week for 12 weeks, with each session lasting for 30 minutes. RESULTS: Self-care, mobility, PEDI total, PBS, and performance of COPM scores increased in the NW group after intervention. Self-care, mobility, and total PEDI increased in the control group as well. However, there was no statistically significant difference found between the groups, except for PBS (P < 0.05). CONCLUSIONS: NW contributed to the implementation of occupational performance, daily living activities, and functional balance. We recommend that NW could be used in the rehabilitation program to engage play-based activities with fun. PMID- 27705005 TI - Future therapeutic potential of SAP-1 in inflammatory bowel diseases. PMID- 27705007 TI - The variation in high sensitive cardiac troponin concentration during haemodialysis treatment is not similar to the biological variation observed in stable end stage renal disease patients. AB - BACKGROUND: Cardiovascular mortality is high in end stage renal disease (ESRD). This study aimed to: (1) calculate within-week within- and between-subject biological variation (CVI and CVG) for hs-cTn in ESRD; (2) determine the magnitude of hs-cTn concentration changes during haemodialysis (HD) treatment; and (3) compare the CVI and CVG to the within and between-subject variation of cTn concentration changes during HD treatments (CVDIFF-I and CVDIFF-G). METHODS: Serum samples were collected from 20 patients before and after 10 consecutive HD treatments. cTn were measured using the hs-cTnT (Roche Diagnostics) and the hs cTnI (Abbott Diagnostics). The CVA, CVI, CVG, CVDIFF-I and CVDIFF-G, were estimated using nested ANOVA. RESULTS: The within-week data showed hs-cTnT CVA, CVI and CVG of 1.6, 7.3 and 94.4%. Reference change values (RCV) were estimated to -18.7-23.0%. The Index of individuality (II) was 0.08. Corresponding values for hs-cTnI were 5.3, 13.2 and 142.4%, whilst the RCV was -32.5-48.2% and the II was 0.10. The mean concentration of cTn decreased by -6.4% (hs-cTnT) and -7.6% (hs-cTnI) during HD treatment. The CVDIFF-I and CVDIFF-G was 4.2 and 6.3% for hs cTnT, and 10.7 and 9.4% for hs-cTnI. The RCVDIFF was -18.2-5.4% (hs-cTnT) and 39.0-23.8% (hs-cTnI), respectively, and the IIDIFF-values were 0.7 and 1.3. CONCLUSIONS: The CVI and CVG are similar to earlier findings. Mean hs-cTn concentrations decreased during HD. The within-subject hs-cTn variation during HD is similar to the between-subject variation, i.e. determining a cut-off value for hs-cTn changes during HD may be useful. PMID- 27705008 TI - A systematic review of resonant voice therapy. AB - PURPOSE: The purpose of this study is to systematically review the literature on resonant voice therapy and to evaluate the level of evidence on the effectiveness of using resonant voice therapy in treating dysphonia. METHOD: Refereed journal papers from 1974 to 2014 were retrieved and reviewed by two independent reviewers using the keywords "Humming, Resonance, Resonant Voice, Semi-occluded or closed tube phonation" using available database systems. Quality of evidence was evaluated by using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULT: Thirteen papers met the search criteria. Nine papers were selected by the two reviewers. Two of the papers were randomised-controlled studies and the other seven were observational studies. At least four types of resonant voice therapies were described. They included the Lessac-Madsen Resonant Voice Therapy, Y-Buzz, Resonance Therapy and Humming. The overall level of quality of evidence was graded as "moderate". CONCLUSION: There were limited studies that investigated the effectiveness of resonant voice therapy. Most studies were small-scale uncontrolled observational studies with the inclusion of only small samples or specific populations. There is clearly a need for more large-scale randomised controlled studies with a wider range of populations to provide further evidence on the effectiveness of resonant voice training for different populations. PMID- 27705009 TI - Treatment Precedes Positive Symptoms in North American Adolescent and Young Adult Clinical High Risk Cohort. AB - Early intervention for psychotic disorders, a growing international priority, typically targets help-seeking populations with emerging psychotic ("positive") symptoms. We assessed the nature of and degree to which treatment of individuals at high risk for psychosis preceded or followed the onset of positive symptoms. The North American Prodrome Longitudinal Study-2 collected psychosocial treatment histories for 745 (98%) of 764 high-risk participants (M age = 18.9, 57% male, 57.5% Caucasian, 19.1% Hispanic) recruited from 8 North American communities. Similar to prior findings, 82% of participants reported psychosocial treatment prior to baseline assessment, albeit with significant variability across sites (71%-96%). Participants first received treatment a median of 1.7 years prior to the onset of a recognizable psychosis-risk syndrome. Only one fourth sought initial treatment in the year following syndrome onset. Although mean sample age differed significantly by site, age at initial treatment (M = 14.1, SD = 5.0) did not. High rates of early treatment prior to syndrome onset make sense in light of known developmental precursors to psychotic disorders but are inconsistent with the low rates of treatment retrospectively reported by first-episode psychosis samples. Findings suggest that psychosis risk studies and clinics may need to more actively recruit and engage symptomatic but non-help-seeking individuals and that community clinicians be better trained to recognize both positive and nonspecific indicators of emerging psychosis. Improved treatments for nonspecific symptoms, as well as the characteristic attenuated positive symptoms, are needed. PMID- 27705010 TI - Therapeutic effects of intensive voice treatment (LSVT LOUD(r)) for children with spastic cerebral palsy and dysarthria: A phase I treatment validation study. AB - PURPOSE: The aim of the present study was to validate and extend the evaluation of treatment outcomes following LSVT LOUD(r) in children with dysarthria secondary to cerebral palsy (CP). METHOD: Seven children (5 females, 6-10 years) with spastic quadriplegia and dysarthria received LSVT LOUD. Outcomes included: (a) quantitative and qualitative indices of communication and social functioning representing therapeutic effects and (b) features of the acoustic signal representing physiological effects on the speech mechanism. A matched group of typically developing children served as controls. Testing occurred just prior to (PRE), immediately following (POST), and at 12 weeks post-treatment (FUP). RESULT: Expert listeners preferred voice quality and articulatory precision of children with CP at FUP as compared to PRE. Acoustic data indicated improvements on select measures of vocal functioning at POST with some maintenance at FUP. Single word intelligibility improved immediately POST, but was not maintained at FUP. Parents rated positive changes in characteristics of voice and speech and qualitative changes in communication at both POST and FUP. CONCLUSION: The present study validated some of the previous LSVT LOUD outcomes in children with dysarthria and CP and extended our understanding of therapeutic effects through qualitative data obtained from extensive parent interviews. PMID- 27705011 TI - Interprofessional education in maternity services: Is there evidence to support policy? AB - Against a backdrop of poor maternity and obstetric care, identified in the Morecambe Bay Inquiry, the UK government has recently called for improvements and heralded investment in training. Given the complex mix of professionals working closely together in maternity services addressing the lack of joined up continuing professional development (CPD) is necessary. This led us to ask whether there is evidence of IPE in maternity services. As part of a wider systematic review of IPE, we searched for studies related to CPD in maternity services between May 2005 and June 2014. A total of 206 articles were identified with 24 articles included after initial screening. Further review revealed only eight articles related to maternity care, none of which met the inclusion criteria for the main systematic review. The main reasons for non-inclusion included weak evaluation, a focus on undergraduate IPE, and articles referring to paediatric/neonatal care only. Fewer articles were found than anticipated given the number of different professions working together in maternity services. This gap suggests further investigation is warranted. PMID- 27705012 TI - How patient-controlled sedation is adopted in clinical practice of sedation for endoscopic retrograde cholangiopancreatography? A prospective study of 1196 cases. AB - OBJECTIVE: Patient-controlled sedation (PCS) has been shown to be a valid choice for sedation during endoscopic retrograde cholangiopancreatography (ERCP) in randomized studies. However, large-scale studies are lacking. MATERIAL AND METHODS: A single center, prospective observational study to determine how sedation for ERCP is administered in clinical setting. All 956 patients undergoing 1196 ERCPs in the endoscopy unit of Helsinki University Central Hospital 2012-2013, methods of sedation and adverse events associated with different sedations were recorded. RESULTS: PCS was attempted a total of 685 times (57%), successful use of PCS was achieved with 526 patients (77% of attempts). PCS device was operated by the anesthesiologist or anesthesia nurse 268 times (22%). PCS was more likely chosen for younger (80.6% for < =60 years vs. 63.8% for >60 years, p<.001) patients and by trainee anesthetists. Anesthesiologist administered propofol sedation was used 240 times (20%). The risk of failure of PCS was increased, if systolic arterial pressure was <90 mmHg, dosage of PCS >17 ml, duration of procedure exceeded 23 min. The risk of failure was lower in patients with primary sclerosing cholangitis (PSC) and if sedation was deeper RASS < =-2. Uneventful PCS was associated with less respiratory and cardiovascular depression than other methods. There were no statistically significant differences in safety profiles with all the methods of sedation. CONCLUSIONS: PCS is readily implemented in clinical practice, is suitable for younger and low-risk patients and is associated with less cardiorespiratory adverse effects.

PMID- 27705013 TI - Colorectal Adenomatous Polyposis: Heterogeneity of Susceptibility Gene Mutations and Phenotypes in a Cohort of Italian Patients. AB - AIMS: Colorectal adenomatous polyposis entailing cancer predisposition is caused by constitutional mutations in different genes. APC is associated with the familial adenomatous polyposis (FAP/AFAP) and MUTYH with the MUTYH-associated polyposis (MAP), while POLE and POLD1 mutations cause the polymerase proofreading associated polyposis (PPAP). METHODS: We screened for mutations in patients with multiple adenomas/FAP: 121 patients were analyzed for APC and MUTYH mutations, and 36 patients were also evaluated for POLE and POLD1 gene mutations. RESULTS: We found 20 FAP/AFAP, 15 MAP, and no PPAP subjects: pathogenic mutations proved to be heterogeneous, and included 5 APC and 1 MUTYH novel mutations. The mutation detection rate was significantly different between patients with 5-100 polyps and those with >100 polyps (p = 8.154 * 10-7), with APC mutations being associated with an aggressive phenotype (p = 1.279 * 10-9). Mean age at diagnosis was lower in FAP/AFAP compared to MAP (p = 3.055 * 10-4). Mutation-negative probands showed a mean age at diagnosis that was significantly higher than FAP/AFAP (p = 3.46986 * 10-7) and included 45.3% of patients with <30 polyps and 70.9% of patients with no family history. CONCLUSIONS: This study enlarges the APC and MUTYH mutational spectra, and also evaluated variants of uncertain significance, including the MUTYH p.Gln338His mutation. Moreover this study underscores the phenotypic heterogeneity and genotype-phenotype correlations in a cohort of Italian patients. PMID- 27705016 TI - A&E waits online.

PMID- 27705026 TI - Hydrogels with smart systems for delivery of hydrophobic drugs. AB - INTRODUCTION: Smart hydrogel systems present opportunities to not only provide hydrophobic molecule encapsulation capability but to also respond to specific delivery routes. Areas covered: An overview of the design principles, preparation methods and applications of hydrogel systems for delivery of hydrophobic drugs is given. It begins with a summary of the advantages of hydrogels as delivery vehicles over other approaches, particularly macromolecular nanocarriers, before proceeding to address the design and preparation strategies and chemistry involved, with a particular focus on the introduction of hydrophobic domains into (naturally) hydrophilic hydrogels. Finally, the applications in different delivery routes are discussed. Expert opinion: Modifications to conventional hydrogels can endow them with the capability to carry hydrophobic drugs but other functions as well, such as the improved mechanical stability, which is important for long-term in vivo residence and/or self-healing properties useful for injectable delivery pathways. These modifications harness hydrophobic-hydrophobic forces, physical interactions and inclusion complexes. The lack of in-depth understanding of these interactions, currently limits more delicate and application-oriented designs. Increased efforts are needed in (i) understanding the interplay of gel formation and simultaneous drug loading; (ii) improving hydrogel systems with respect to their biosafety; and (iii) control over release mechanism and profile. PMID- 27705027 TI - Lessons to be learned from serum biomarkers in psoriasis and IBD - the potential role in SpA. AB - INTRODUCTION: Early diagnosis, monitoring of disease activity, prediction of treatment response, and structural outcome remain major challenges in spondyloarthritis (SpA). Biomarkers could play a role in addressing these challenges, but in SpA there is a lack of suitable biomarkers. Areas covered: As SpA is clinically and pathophysiologically closely related to psoriasis and inflammatory bowel disease (IBD), we reviewed in literature, the value of serum biomarkers in these conditions with the aim to find potential candidates for assessing SpA. Expert commentary: Candidates of interest were antimicrobial peptides, including serum human beta defensin-2 (hBD-2) and lipocalin-2 (LCN-2), and class-1 MHC molecule beta2-microglobulin. Since these biomarkers are relevant in psoriasis and/or IBD from a pathophysiological point of view, and may play a role in the pathogenesis of SpA, we recommend further exploration of their value as biomarker in the diagnosis and prognosis of SpA. PMID- 27705028 TI - Type 2 diabetes and metabolic syndrome - adipokine levels and effect of drugs. AB - Type 2 diabetes mellitus (T2DM) is a consequence of complex interactions among multiple genetic variants and environmental risk factors. This complex disorder is also characterized by changes in various adipokines. In this study, our objective was to estimate the levels of adiponectin, leptin, and resistin (ALR) in T2DM patients, besides studying the effect of various drugs on their levels. Study participants included 400 diabetic and 300 normal patients from the Department of Endocrinology and Department of Biochemistry, Govt Medical College Srinagar. Subjects were categorized under various groups, i.e., Group 1 (metformin treated) and Group 2 (glimepiride treated), and cases were also categorized as obese with T2DM (Group A), obese without T2DM (Group B), and T2DM only (Group C). The serum ALR levels were estimated by ELISA (Alere), and biochemical parameters were also evaluated before and after treatment. Adiponectin levels were found to be significantly lower in T2DM cases as compared to controls (12 +/- 5.5 versus 22.5 +/- 7.9 MUg/ml), while leptin and resistin levels were found to be significantly higher than controls (14.3 +/- 7.4 versus 7.36 +/- 3.73 ng/ml) (13.4 +/- 1.56 versus 7.236 +/- 2.129 pg/ml). Taking the effect of drugs into consideration, the effect on adiponectin and resistin levels was found to be highly significant in Group 2 before and after treatment (11 +/- 5 versus 19.2 +/- 4.5 MUg/ml) (13.6 +/- 2.5 versus 7.3 +/- 2.9 pg/ml), while more effect was observed in leptin among Group 1 (metformin)-treated cases (27 +/- 15 ng/ml versus 15 +/- 15 ng/ml). Further the adiponectin levels were found to be significantly lower in Group B, while leptin and resistin levels were found to be significantly higher among obese cases when compared to T2DM cases only. Glimepiride also shows more effect on FBG, HbA1c% levels, while metformin shows more effect on Lipid profile levels. From the study, it can be concluded that ALR levels are affected by use of antidiabetic drugs among which glimepiride shows more effect on adiponectin and resistin levels, while leptin gets affected more by metformin. It can also be proposed that ALR levels are not affected by diabetes only, suggesting that their alterations in T2DM may be due to obesity as we observed more ALR changes in obese cases when compared to T2DM cases, and so there might be an important link between adiposity and insulin resistance. PMID- 27705029 TI - Patient safety competence for final-year health professional students: Perceptions of effectiveness of an interprofessional education course. AB - As final-year medical and nursing students will soon play key roles in frontline patient care, their preparedness for safe, reliable care provision is of special importance. We assessed patient safety competencies of final-year health profession students, and the effect of a 1-day patient safety education programme on these competencies. A cross-sectional survey was conducted with 233 students in three colleges of medicine, nursing, and traditional medicine in Seoul. A before-and-after study followed to evaluate the effectiveness of the curriculum. Patient safety competency was measured using the Health-Professional Education for Patients Safety Survey (H-PEPSS) and an objective patient safety knowledge test. The mean scores were 3.4 and 1.7 out of 5.0, respectively. The communication domain was rated the highest and the teamwork domain was rated the lowest. H-PEPSS scores significantly differed between the students from three colleges. The 1-day patient safety education curriculum significantly improved H PEPSS and knowledge test scores. These results indicated that strengthening patient safety competencies, especially teamwork, of students is required in undergraduate healthcare curricula. A 1-day interprofessional patient safety education programme may be a promising strategy. The findings suggest that interprofessional patient safety education needs to be implemented as a core undergraduate course to improve students' safety competence.

AB - The aim of this study was to obtain baseline information on staff attitudes and perceptions of interprofessional collaboration on a newly formed interprofessional education unit. The Assessment of Interprofessional Team Collaboration Scale (AITCS) was administered to 54 interprofessional team members on a 30-bed medical interprofessional education (IPE) unit. We found that the team members respected each other but felt they needed more organisational support to further develop team skills. Additionally, team members noted that they did not have enough time for team reflection or to make changes to the team processes. The results obtained from this study will help to develop and refine educational strategies to assist the staff working on the IPE unit. PMID- 27705031 TI - A short-term cost-utility analysis of insulin degludec versus insulin glargine U100 in patients with type 1 or type 2 diabetes in Denmark. AB - BACKGROUND AND AIMS: Insulin degludec is an insulin analog with an ultra-long duration of action that exhibits less intra-patient variability in its glucose lowering activity, and reduces nocturnal, overall, and severe hypoglycemia relative to insulin glargine. The aim of the present study was to evaluate the cost-effectiveness of insulin degludec relative to insulin glargine in patients with: type 1 diabetes (T1D), type 2 diabetes receiving basal-only therapy (T2DBOT), and type 2 diabetes receiving basal-bolus therapy (T2DBB) in Denmark. METHODS: A short-term (1 year) cost-utility model was developed to model insulin use, non-severe and severe hypoglycemia, and self-monitoring of blood glucose in patients using insulin degludec and insulin glargine from the perspective of a Danish healthcare payer. Where possible, data were derived from Danish patients with diabetes and meta-analyses of clinical trials comparing insulin degludec with insulin glargine. Using these characteristics, the model estimated costs and quality-adjusted life years (QALYs) gained for the two insulin regimens in each of the three diabetes populations. RESULTS: Insulin degludec dominated insulin glargine (i.e. reduced costs while improving quality-adjusted life expectancy) in patients with T1D and patients with type 2 diabetes using a basal-only insulin regimen. In the T2DBB cohort, insulin degludec was associated with an incremental cost-effectiveness ratio of DKK 221,063 per QALY gained, which would be considered cost-effective at a willingness-to-pay threshold of EUR 30,000 (~DKK 224,000) per QALY gained. Sensitivity analysis showed that results were most affected by changes in hypoglycemia rate ratio assumptions, but were broadly insensitive to changes in individual input parameters. CONCLUSIONS: Insulin degludec reduces incidence of hypoglycemia and improves quality-of-life in patients with diabetes. Over a 1-year time horizon, insulin degludec resulted in cost savings relative to insulin glargine in T1D and T2DBOT cohorts, while being cost-effective in T2DBB.

AB - PURPOSE: This paper examined the production of intonation patterns in children with developmental dysarthria associated with cerebral palsy (CP) prior to and after speech intervention focussing on respiration and phonation. The study further sought to establish whether intonation performance might be related to changes in speech intelligibility. METHOD: Intonation patterns were examined using connected speech samples of 15 older children with moderate to severe developmental dysarthria due to CP (9 females; age range: 11-18). Recordings were made prior to and after speech intervention based on a systems approach. Analyses are focussed on the use of intonation patterns, pitch accentuation and phrasing. RESULT: Group analyses showed a significant increase in the use of rising intonation patterns after intervention. There were also some indications that this increase might have been related to gains in speech intelligibility for some of the children. No changes were observed regarding pitch accentuation and phrasing following intervention. CONCLUSION: The findings highlight that changes can occur in the use of intonation patterns in children with dysarthria and CP following speech systems intervention. It is hypothesised that the emergence of the rising pattern in some of the children's intonational inventories possibly reflected improved breath support and control of laryngeal muscles. PMID- 27705033 TI - Interprofessional education in the Arabic-speaking Middle East: Perspectives of pharmacy academics. AB - The current status of interprofessional education (IPE) in Arabic Middle Eastern countries is largely unexamined and there is a need to assess IPE and collaborative practice in these countries. As faculty attitudes towards IPE are believed to be one of the main factors that affect the successful integration of IPE into the different healthcare curricula, this article aims to explore the attitudes and views of pharmacy academics in Arabic-speaking Middle Eastern countries towards IPE and collaborative practice. The findings from this article are part of a larger study investigating pharmacy's perspectives of IPE and collaborative practice in Qatar and the Middle East. An online survey which included three validated scales was used to gather information from pharmacy academics at 89 pharmacy schools in 14 countries. The response rate was 107 out of 334 (32%) and the majority of the respondents were from Jordan, Qatar, Lebanon, and Saudi Arabia. Statistical analysis was completed descriptively as well as inferentially using a series of independent t-tests. Overall pharmacy academics had positive attitudes towards IPE. The majority of the respondents, 90.8% (n = 99), perceived IPE to be important. Age, likelihood to engage in IPE, and years of IPE experience were the factors that were related to faculty members' attitudes towards IPE. Highly perceived barriers for implementing IPE included cultural challenges for each profession, scheduling common courses, and activities in addition to limited resources. The study findings indicated that pharmacy academics in the Middle East are ready to pursue IPE. These results can serve as impetus for implementing IPE in Middle Eastern countries. PMID- 27705034 TI - The High-Pull Exercise: A Comparison Between a VersaPulley Flywheel Device and the Free Weight. AB - The aim of this study was to examine the kinematics and kinetics (force, velocity, and acceleration) and blood lactate concentration with the VersaPulley (VP) device in comparison with free-weight (FW) exercise at a similar external load. Fifteen rugby players randomly performed 2 training sessions of 6 sets of 6 repetitions with 20 s of recovery between sets of the high-pull exercise with the VP and the FW. The training sessions were separated by 72 h. Barbell displacement (cm), peak velocity (m/s), peak acceleration (m/s2), mean propulsive velocity (m/s), mean propulsive acceleration (m/s2), propulsive phase (%), and mean and maximal force (N) were continuously recorded during each repetition. Blood lactate concentration was measured after each training session (end) and 3 min and 5 min later. Barbell displacement (+4.8%, small ES), peak velocity (+4.5% small ES), mean propulsive acceleration (+8.8%, small ES), and eccentric force (+26.7, large ES) were substantially higher with VP than with FW. Blood lactate concentration was also greater after the VP exercise (end +32.9%, 3 min later +36%, 5 min later +33.8%; large ES). Maximal concentric force was substantially higher with FW than VP during the 6th set (+6.4%, small ES). In the cohort and exercise investigated in the current study, VP training can be considered an efficient training device to induce an accentuated eccentric overload and augmented metabolic demands (ie, blood lactate concentration).

AB - New poly(ester-amide) copolymers modified with polyethers were developed for carboplatin encapsulation. These new copolymers contain hydrophobic blocks made of tyrosine derivative and dimer fatty acid, and poly(ethylene glycol) (PEG) as hydrophilic blocks. Short-term hydrolytic degradation revealed high water absorption, slight increase of pH of simulated body fluid and change of sample shape, which indicated the erosive mechanism of polymers degradation. Poly(ester amide)-PEG copolymers were used for microspheres preparation and carboplatin encapsulation. A double emulsification process was used to produce microspheres with an average diameter of 20-30 MUm. It was found that the amount of drug released was controlled by the molecular mass of PEG used for microspheres preparation. Mathematical models were used to elucidate the release mechanism of the carboplatin from the microspheres. The results demonstrate that poly(ester amide)-PEG copolymers may be used for targeted carboplatin encapsulation and release. PMID- 27705050 TI - The Effect of Backpack Carriage on the Biomechanics of Walking: A Systematic Review and Preliminary Meta-Analysis. AB - The aim of this systematic review was to evaluate the impact of bilaterally symmetrical backpack systems borne on the posterior trunk on walking biomechanics, as backpacks represent the most prevalent method of load carriage in the military and civilian population. A search of electronic databases was performed for studies that only investigated posteriorly-borne backpack carriage during level-grade walking (treadmill and over ground). Methodology of studies was assessed, and both meta-analysis and qualitative synthesis were completed. Fifty-four studies were included in this review. In summary, the available literature showed that backpack carriage in walking was associated with an increased trunk flexion angle, increased hip and ankle range of motion, increased vertical and horizontal ground reaction force, increased cadence, and reduced stride length. Several variations in backpack carriage protocols could explain between-study variations in results, including: walking speed, backpack carriage skill level, the use of a hip belt, and posterior displacement of the load away from the trunk. The findings of this systematic review will inform backpack carriage practices in the area of injury risk assessment and physical performance enhancement. PMID- 27705051 TI - RNA-binding proteins are a major target of silica nanoparticles in cell extracts. AB - Upon contact with biological fluids, nanoparticles (NPs) are readily coated by cellular compounds, particularly proteins, which are determining factors for the localization and toxicity of NPs in the organism. Here, we improved a methodological approach to identify proteins that adsorb on silica NPs with high affinity. Using large-scale proteomics and mixtures of soluble proteins prepared either from yeast cells or from alveolar human cells, we observed that proteins with large unstructured region(s) are more prone to bind on silica NPs. These disordered regions provide flexibility to proteins, a property that promotes their adsorption. The statistical analyses also pointed to a marked overrepresentation of RNA-binding proteins (RBPs) and of translation initiation factors among the adsorbed proteins. We propose that silica surfaces, which are mainly composed of Si-O- and Si-OH groups, mimic ribose-phosphate molecules (rich in -O- and -OH) and trap the proteins able to interact with ribose-phosphate containing molecules. Finally, using an in vitro assay, we showed that the sequestration of translation initiation factors by silica NPs results in an inhibition of the in vitro translational activity. This result demonstrates that characterizing the protein corona of various NPs would be a relevant approach to predict their potential toxicological effects. PMID- 27705053 TI - Electrochemotherapy of mucosal head and neck tumors: a systematic review. AB - BACKGROUND: Electrochemotherapy, the combination of electroporation and chemotherapy, is mainly used in the palliative setting for treatment of cutaneous and subcutaneous metastases; however, new applications are continuously being explored. Patients with head and neck cancer are primarily treated with surgery and/or radio-chemotherapy. In the setting of local recurrence with no further curative treatment options available, electrochemotherapy could be of value. We therefore performed a systematic search of the present literature. MATERIALS AND METHODS: Eligible studies presented data from patients with head and neck cancer treated across the mucosal surface with electrochemotherapy. The search resulted in 11 studies with a total of 72 patients. RESULTS: Overall complete response was reported as good, especially in primary small tumors. Side effects were minor in primary tumors whereas large, recurrent tumors displayed more frequent side effects and some serious adverse events. Design and structure of the studies differed considerably, making general comparisons difficult. CONCLUSION: Few studies concerning electrochemotherapy on mucosal head and neck tumors are available and they are not easily comparable. Overall response to treatment is good; nonetheless, further systematic studies are warranted. PMID- 27705052 TI - RENEB biodosimetry intercomparison analyzing translocations by FISH. AB - PURPOSE: In the framework of RENEB, several biodosimetry exercises were conducted analyzing different endpoints. Among them, the analysis of translocations is considered the most useful method for retrospective biodosimetry due to the relative stability of their frequency with post irradiation time. The aim of this study was to harmonize the accuracy of translocation-based biodosimetry within the RENEB consortium. MATERIALS AND METHODS: An initial telescoring exercise analyzing FISH metaphase images was done to harmonize chromosome aberration descriptions. Then two blind intercomparison exercises (IE) were performed, by sending irradiated blood samples to each partner. Samples were cultured and stained by each partner using their standard protocol and translocation frequency was used to produce dose estimates. RESULTS: The coefficient of variation in the 1st IE (CV = 0.34) was higher than in the 2nd IE (CV = 0.16 and 0.23 in the two samples analyzed), for the genomic frequency of total translocations. Z-score analysis revealed that eight out of 10 and 17 out of 20 dose estimates were satisfactory in the 1st and 2nd IE, respectively. CONCLUSIONS: The results obtained indicate that, despite the problems identified in few partners, which can be corrected, the RENEB consortium is able to carry out retrospective biodosimetry analyzing the frequency of translocations by FISH. PMID- 27705054 TI - Enhancement of radiosensitivity of melanoma cells by pegylated gold nanoparticles under irradiation of megavoltage electrons. AB - PURPOSE: Gold nanoparticles (GNP) have significant potential as radiosensitizer agents due to their distinctive properties. Several studies have shown that the surface modification of nanoparticles with methyl polyethylene glycol (mPEG) can increase their biocompatibility. However, the present study investigated the radiosensitization effects of mPEG-coated GNP (mPEG-GNP) in B16F10 murine melanoma cells under irradiation of 6 MeV Electron beam. MATERIALS AND METHODS: The synthesized GNP were characterized by UV-Visible spectroscopy, dynamic light scattering, transmission electron microscopy, and zeta potential. Enhancement of radiosensitization was evaluated by the clonogenic assay at different radiation doses of megavoltage electron beams. RESULTS: It was observed that mPEG-GNP with a hydrodynamic size of approximately 50 nm are almost spherical and cellular uptake occurred at all concentrations. Both proliferation efficiency and survival fraction decreased with increasing mPEG-GNP concentration. Furthermore, significant GNP sensitization occurred with a maximum dose enhancement factor of 1.22 at a concentration of 30 MUM. CONCLUSIONS: Pegylated-GNP are taken up by B16F10 cancer cells and cause radiosensitization in the presence of 6 MeV electrons. The radiosensitization effects of GNP may probably be due to biological processes. Therefore, the underlying biological mechanisms beyond the physical dose enhancement need to be further clarified. PMID- 27705055 TI - A Comparison of Vertical Stiffness Values Calculated from Different Measures of Center of Mass Displacement in Single-Leg Hopping. AB - This study assessed the agreement between Kvert calculated from 4 different methods of estimating vertical displacement of the center of mass (COM) during single-leg hopping. Healthy participants (N = 38) completed a 10-s single-leg hopping effort on a force plate, with 3D motion of the lower limb, pelvis, and trunk captured. Derived variables were calculated for a total of 753 hop cycles using 4 methods, including: double integration of the vertical ground reaction force, law of falling bodies, a marker cluster on the sacrum, and a segmental analysis method. Bland-Altman plots demonstrated that Kvert calculated using segmental analysis and double integration methods have a relatively small bias (0.93 kN?m-1) and 95% limits of agreement (-1.89 to 3.75 kN?m-1). In contrast, a greater bias was revealed between sacral marker cluster and segmental analysis ( 2.32 kN?m-1), sacral marker cluster and double integration (-3.25 kN?m-1), and the law of falling bodies compared with all methods (17.26-20.52 kN?m-1). These findings suggest the segmental analysis and double integration methods can be used interchangeably for the calculation of Kvert during single-leg hopping. The authors propose the segmental analysis method to be considered the gold standard for the calculation of Kvert during single-leg, on-the-spot hopping. PMID- 27705057 TI - Reliability and Validity of Quantitative Video Analysis of Baseball Pitching Motion. AB - Video recordings are used to quantitatively analyze pitchers' techniques. However, reliability and validity of such analysis is unknown. The purpose of the study was to investigate the reliability and validity of joint and segment angles identified during a pitching motion using video analysis. Thirty high school baseball pitchers participated. The pitching motion was captured using 2 high speed video cameras and a motion capture system. Two raters reviewed the videos to digitize the body segments to calculate 2-dimensional angles. The corresponding 3-dimensional angles were calculated from the motion capture data. Intrarater reliability, interrater reliability, and validity of the 2-dimensional angles were determined. The intrarater and interrater reliability of the 2 dimensional angles were high for most variables. The trunk contralateral flexion at maximum external rotation was the only variable with high validity. Trunk contralateral flexion at ball release, trunk forward flexion at foot contact and ball release, shoulder elevation angle at foot contact, and maximum shoulder external rotation had moderate validity. Two-dimensional angles at the shoulder, elbow, and trunk could be measured with high reliability. However, the angles are not necessarily anatomically correct, and thus use of quantitative video analysis should be limited to angles that can be measured with good validity. PMID- 27705056 TI - In Vivo Kinematics of Healthy and Osteoarthritic Knees During Stepping Using Density-Based Image-Matching Techniques. AB - The purpose of this study was to investigate in vivo kinematics in healthy and osteoarthritic (OA) knees during stepping using image-matching techniques. Six healthy volunteers and 14 patients with a medial OA knee before undergoing total knee arthroplasty performed stepping under periodic anteroposterior radiograph images. We analyzed the three-dimensional kinematic parameters of knee joints using radiograph images and CT-derived digitally reconstructed radiographs. The average extension/flexion angle ranged 6 degrees /53 degrees and 16 degrees /44 degrees in healthy and OA knees, with significant difference in extension (P = .02). The average varus angle was -2 degrees and 6 degrees in healthy and OA knees, with a significant difference (P = .03). OA knees showed 1.7 degrees of significantly larger varus thrust (P = .04) and 4.2 mm of significantly smaller posterior femoral rollback (P = .04) compared with healthy knees. Coronal limb alignment in OA knees significantly correlated with varus thrust (R2 = .36, P = .02) and medial shift of the femur (R2 = .34, P = .03). Both normal and OA knees showed no transverse plane instability, including anteroposterior, mediolateral directions, or axial rotation. In conclusion, OA knees demonstrated different kinematics during stepping from normal knees: less knee extension, larger varus thrust, less posterior translation, and larger medial shift. PMID- 27705058 TI - Estimates of Running Ground Reaction Force Parameters from Motion Analysis. AB - We compared running mechanics parameters determined from ground reaction force (GRF) measurements with estimated forces obtained from double differentiation of kinematic (K) data from motion analysis in a broad spectrum of running speeds (1.94-5.56 m?s-1). Data were collected through a force-instrumented treadmill and compared at different sampling frequencies (900 and 300 Hz for GRF, 300 and 100 Hz for K). Vertical force peak, shape, and impulse were similar between K methods and GRF. Contact time, flight time, and vertical stiffness (kvert) obtained from K showed the same trend as GRF with differences < 5%, whereas leg stiffness (kleg) was not correctly computed by kinematics. The results revealed that the main vertical GRF parameters can be computed by the double differentiation of the body center of mass properly calculated by motion analysis. The present model provides an alternative accessible method for determining temporal and kinetic parameters of running without an instrumented treadmill. PMID- 27705059 TI - Accuracy of a Wearable Sensor for Measures of Head Kinematics and Calculation of Brain Tissue Strain. AB - Wearable kinematic sensors can be used to study head injury biomechanics based on kinematics and, more recently, based on tissue strain metrics using kinematics driven brain models. These sensors require in-situ calibration and there is currently no data conveying wearable ability to estimate tissue strain. We simulated head impact (n = 871) to a 50th percentile Hybrid III (H-III) head wearing a hockey helmet instrumented with wearable GForceTracker (GFT) sensors measuring linear acceleration and angular velocity. A GFT was also fixed within the H-III head to establish a lower boundary on systematic errors. We quantified GFT errors relative to H-III measures based on peak kinematics and cumulative strain damage measure (CSDM). The smallest mean errors were 12% (peak resultant linear acceleration) and 15% (peak resultant angular velocity) for the GFT within the H-III. Errors for GFTs on the helmet were on average 54% (peak resultant linear acceleration) and 21% (peak resultant angular velocity). On average, the GFT inside the helmet overestimated CSDM by 0.15. PMID- 27705060 TI - Effective Propulsion in Swimming: Grasping the Hydrodynamics of Hand and Arm Movements. AB - In this paper, a literature review is presented regarding the hydrodynamic effects of different hand and arm movements during swimming with the aim to identify lacunae in current methods and knowledge, and to distil practical guidelines for coaches and swimmers seeking to increase swimming speed. Experimental and numerical studies are discussed, examining the effects of hand orientation, thumb position, finger spread, sculling movements, and hand accelerations during swimming, as well as unsteady properties of vortices due to changes in hand orientation. Collectively, the findings indicate that swimming speed may be increased by avoiding excessive sculling movements and by spreading the fingers slightly. In addition, it appears that accelerating the hands rather than moving them at constant speed may be beneficial, and that (in front crawl swimming) the thumb should be abducted during entry, catch, and upsweep, and adducted during the pull phase. Further experimental and numerical research is required to confirm these suggestions and to elucidate their hydrodynamic underpinnings and identify optimal propulsion techniques. To this end, it is necessary that the dynamical motion and resulting unsteady effects are accounted for, and that flow visualization techniques, force measurements, and simulations are combined in studying those effects. PMID- 27705061 TI - Errors in Shoulder Joint Position Sense Mainly Come from the Glenohumeral Joint. AB - While synchronous movement of the glenohumeral and scapulothoracic joints has been emphasized in previous kinematics studies, most investigations of shoulder joint position sense have treated the shoulder complex as a single joint. The purposes of this study were to investigate the joint position sense errors of the humerothoracic, glenohumeral, and scapulothoracic joints at different elevation angles and to examine whether the errors of the glenohumeral and scapulothoracic joints contribute to the errors of the humerothoracic joint. Fifty-one subjects with healthy shoulders were recruited. Active joint position sense of the humerothoracic, glenohumeral, and scapulothoracic joints was measured at 50 degrees , 70 degrees , and 90 degrees of humerothoracic elevation in the scapular plane. The results showed that while scapulothoracic joint position sense errors were not affected by target angles, there was an angle effect on humerothoracic and glenohumeral errors, with errors decreasing as the target angles approached 90 degrees of elevation. The results of a multiple regression analysis revealed that glenohumeral errors explained most of the variance of the humerothoracic errors and that scapulothoracic errors had a weaker predictive relationship with humerothoracic errors. Therefore, it may be necessary to test scapular joint position sense separately in addition to the assessment of the overall shoulder joint position sense. PMID- 27705062 TI - Decoupling the Wrist: A Cadaveric Experiment Examining Wrist Kinematics Following Midcarpal Fusion and Scaphoid Excision. AB - At the wrist, kinematic coupling (the relationship between flexion-extension and radial-ulnar deviation) facilitates function. Although the midcarpal joint is critical for kinematic coupling, many surgeries, such as 4-corner fusion (4CF) and scaphoidexcision 4-corner fusion (SE4CF), modify the midcarpal joint. This study examines how 4CF and SE4CF influence kinematic coupling by quantifying wrist axes of rotation. Wrist axes of rotation were quantified in 8 cadaveric specimens using an optimization algorithm, which fit a 2-revolute joint model to experimental data. In each specimen, data measuring the motion of the third metacarpal relative to the radius was collected for 3 conditions (nonimpaired, 4CF, SE4CF). The calculated axes of rotation were compared using spherical statistics. The angle between the axes of rotation was used to assess coupling, as the nonimpaired wrist has skew axes (ie, angle between axes approximately 60 degrees ). Following 4CF and SE4CF, the axes are closer to orthogonal than those of the nonimpaired wrist. The mean angle (+/-95% confidence interval) between the axes was 92.6 degrees +/- 25.2 degrees and 99.8 degrees +/- 22.0 degrees for 4CF and SE4CF, respectively. The axes of rotation defined in this study can be used to define joint models, which will facilitate more accurate computational and experimental studies of these procedures. PMID- 27705063 TI - A Comparison of Body Segment Inertial Parameter Estimation Methods and Joint Moment and Power Calculations During a Drop Vertical Jump in Collegiate Female Soccer Players. AB - Athletic individuals may differ in body segment inertial parameter (BSIP) estimates due to differences in body composition, and this may influence calculation of joint kinetics. The purposes of this study were to (1) compare BSIPs predicted by the method introduced by de Leva1 with DXA-derived BSIPs in collegiate female soccer players, and (2) examine the effects of these BSIP estimation methods on joint moment and power calculations during a drop vertical jump (DVJ). Twenty female NCAA Division I soccer players were recruited. BSIPs of the shank and thigh (mass, COM location, and radius of gyration) were determined using de Leva's method and analysis of whole-body DXA scans. These estimates were used to determine peak knee joint moments and power during the DVJ. Compared with DXA, de Leva's method located the COM more distally in the shank (P = .008) and more proximally in the thigh (P < .001), and the radius of gyration of the thigh to be further from the thigh COM (P < .001). All knee joint moment and power measures were similar between methods. These findings suggest that BSIP estimation may vary between methods, but the impact on joint moment calculations during a dynamic task is negligible. PMID- 27705064 TI - Age-Related Locomotion Characteristics in Association with Balance Function in Young, Middle-Aged, and Older Adults. AB - The purpose of this study was to examine age-related gait characteristics and their associations with balance function in older adults. A total of 51 adult volunteers participated. All subjects underwent locomotion analysis using a 3D motion analysis and 12-channel dynamic electromyography system. Dynamic balance function was assessed by the Berg Balance Scale. Older adults showed a higher level of muscle activation than young adults, and there were significant positive correlations between increased age and activation of the trunk and thigh muscles in the stance and swing phase of the gait cycle. In particular, back extensor muscle activity was mostly correlated with the dynamic balance in older adults. Thus, back extensor muscle activity in walking may provide a clue for higher falling risk in older adults. This study demonstrates that the back extensor muscles play very important roles with potential for rehabilitation training to improve balance and gait in older adults.

AB - OBJECTIVE: To investigate half-marathon runners' frequency of use of recovery strategies, perceptions regarding the most beneficial recovery strategy, and reasons for using recovery strategies. DESIGN: Cross-sectional survey. PARTICIPANTS: 186 participants of the 13.1 mile BUPA Great North Run 2013. METHODS: A questionnaire was developed which required participants to indicate how frequently they used 12 different recovery strategies, identify which recovery strategy they believed to be most beneficial, and rank 6 reasons for using recovery strategies in order of importance. Data were analyzed using a Friedman nonparametric ANOVA and additional nonparametric tests. RESULTS: All participants used recovery strategies. Stretching was the most commonly used recovery strategy (P < .001), whereas the use of nutritional supplements was the most commonly selected most beneficial recovery strategy. More than 50% of respondents indicated that they never used strategies such as kinesio tape (80%), hydrotherapy (78%), or ice baths (71%). A significant difference was observed between reasons for using recovery strategy (chi2 (5) = 292.29, P < .001). Reducing muscle tightness (rank 4.87) and reducing injury (rank 4.35) were the most frequently chosen most important reasons for using recovery strategies. Minor sex and age differences in the responses were identified. CONCLUSION: Recovery strategy usage appears to be widespread among half-marathon runners; however, disparities exist between the frequency of use and perceived effectiveness of different recovery strategies. Further research in this area is needed to facilitate the development of recovery strategy guidelines which are both evidence-based and practically relevant. PMID- 27705066 TI - Home Exercises Versus On-Site Rehabilitation in the Management of Lateral Elbow Tendinopathy: A Critically Appraised Topic. AB - Clinical Scenario: Lateral elbow tendinopathy (LE) is a common musculoskeletal condition that often results in pain and disability. An array of conservative interventions have been shown to improve patient outcomes in outpatient rehabilitation clinics. However, with the rise in health care costs, patients and rehabilitation specialists have opted to reduce the number of in-house visits and focus on home exercise programs (HEPs). As a result, many rehabilitation specialists and patients now depend on HEPs as the primary intervention to treat LE. Focused Clinical Question: For individuals with LE, is there evidence to suggest that HEPs are as effective as traditional on-site rehabilitation for reducing pain and disability? Summary of Search, Best Evidence Appraised, and Key Findings: The literature was searched for studies comparing HEP to on-site rehabilitation in the management of LE. Two clinical controlled trials (CCTs) were included. No studies suggested that HEPs demonstrated equal or improved outcomes in pain or disability. Both studies concluded that on-site rehabilitation services were more effective at reducing pain and disability in the short term. More research is needed to compare the cost effectiveness of both HEP and on-site rehabilitation. Clinical Bottom Line: Based on 2 CCTs, it can be concluded that there is moderate evidence to suggest that patients with LE experience decreased pain and disability scores with on-site rehabilitation compared to a guided HEP in the short term. The authors could not draw a conclusion regarding long-term effects of treatments or cost effectiveness of the 2 approaches. Strength of Recommendation: Based on the Centre for Evidence Based Medicine, there is level B evidence that a HEP only was not as effective as on site rehabilitation services in patients with LE. PMID- 27705067 TI - Walking Up to One Hour Per Week Maintains Mobility as Older Women Age: Findings from an Australian Longitudinal Study. AB - The aim of this study was to identify determinants of walking and whether walking maintained mobility among women as they transition from their mid-70s to their late 80s. We used 12 years of follow-up data (baseline 1999) from the Australian Longitudinal Study on Women's Health (n = 10,322). Fifteen determinants of walking were included in the analysis and three indicators of mobility. Longitudinal data analyses techniques were employed. Thirteen of the 15 determinants were significant predictors of walking. Women in their mid-70s who walked up to 1 hr per week were less likely to experience loss of mobility in very old age, including reduced likelihood of using a mobility aid. Hence, older women who do no walking should be encouraged to walk to maintain their mobility and their independence as they age, particularly women in their 70s and 80s who smoke, are overweight, have arthritis, or who have had a recent fall. PMID- 27705068 TI - Antiobesity Effects of Salvia plebeia R. Br. Extract in High-Fat Diet-Induced Obese Mice. AB - This study was designed to investigate the antiobesity effects of Salvia plebeia R. Br. ethanolic extracts (SPE) in mice fed high-fat diets (HFD). Male C57BL/6J mice were randomly assigned to four groups: normal diet (Chow), high-fat diet (HFD, 45% fat), HFD+SPE 200 (200 mg/kg b.w.), and HFD+SPE 400 (400 mg/kg b.w.). Extracts were administered orally every day for 8 weeks. Increases in body/fat weight and feed efficiency ratio were monitored in all mice. In addition, obesity resulting from feeding HFD to the mice was confirmed by the increase of glucose level, aspartate transaminase, alanine transaminase, triglyceride (TG), high density lipoprotein cholesterol, very low-density lipoprotein-c, leptin, and adiponectin in blood. The SPE-treated mice gained less body and mesenteric/subcutaneous adipose tissues weights and had lower TG, very low density lipoprotein cholesterol, leptin, and glucose level in serum, compared to the HFD group. Moreover, histopathological examinations revealed that the size of adipocytes in liver and adipose tissue was significantly decreased by SPE, compared to the HFD group. The expression of adipogenesis transcription factors (e.g., peroxisome proliferator activated receptor gamma and CCAAT/enhancer binding protein alpha) and lipogenesis-related target genes (adipocyte fatty acid binding protein 2, lipoprotein lipase, fatty acid synthase, and sterol regulatory element-binding transcription factor 1c) in HFD-induced obese mice was decreased by SPE treatment. These results suggest that SPE attenuates the fat accumulation in HFD-induced obese mice by suppressing the expressions of genes related to adipogenesis and lipogenesis activity. Therefore, SPE could be developed as a potential therapy for reduction of body weight and antiobesity intervention. PMID- 27705069 TI - Exercise Test Performance Reveals Evidence of the Cardiorespiratory Fitness Hypothesis. AB - Positive physiologic and cognitive responses to aerobic exercise have resulted in a proposed cardiorespiratory (CR) fitness hypothesis in which fitness gains drive changes leading to cognitive benefit. The purpose of this study was to directly assess the CR fitness hypothesis. Using data from an aerobic exercise trial, we examined individuals who completed cardiopulmonary and cognitive testing at baseline and 26 weeks. Change in cognitive test performance was not related to CR fitness change (r2 = .06, p = .06). However, in the subset of individuals who gave excellent effort during exercise testing, change in cognitive test performance was related to CR fitness change (r2 = .33, p < .01). This was largely due to change in the cognitive domain of attention (r2 = .36, p < .01). The magnitude of change was not explained by duration of exercise. Our findings support further investigation of the CR fitness hypothesis and mechanisms by which physiologic adaptation may drive cognitive change. PMID- 27705070 TI - The Effectiveness of Low-Dye Taping in Reducing Pain Associated With Plantar Fasciitis. AB - Plantar fasciitis is one of the most common musculoskeletal disorders of the foot. Initial treatment of plantar fasciitis is typically conservative and may include heel padding, steroid injections, night splinting, calf stretching, ultrasound, foot orthoses, and taping. However, while custom foot orthoses are a common treatment method for plantar fasciitis, there is often a waiting period of a few weeks for them to be manufactured and delivered. Therefore, taping of the foot is often used as a temporary treatment to alleviate pain during the initial waiting period. Furthermore, taping may also be used as an alternative to foot orthoses for patients who may not tolerate the plantar pressures of an orthotic or for tight-fitting footwear that may not accommodate insoles. Specifically, the low-Dye taping (LDT) technique is one of the most frequently used methods, and recent literature has suggested that it may improve pain outcomes. Therefore, this critically appraised topic was conducted to determine the extent to which current evidence supports the use of LDT to reduce pain in patients with plantar fasciitis. PMID- 27705072 TI - Acute Effects of Posture Shirts on Rounded-Shoulder and Forward-Head Posture in College Students. AB - CONTEXT: Rounded-shoulder and forward-head posture can be contributing factors to shoulder pain. Corrective techniques such as manual therapy and exercise have been shown to improve these altered postures, but there is little evidence that corrective garments such as posture shirts can alter posture. OBJECTIVES: To determine the acute effects of corrective postureshirt use on rounded-shoulder and forward-head posture in asymptomatic college students. DESIGN: Repeated measures intervention study with counterbalanced conditions. SETTING: Research laboratory. PARTICIPANTS: 24 members of the general student body of a university, 18-25 y old, with a forward shoulder angle (FSA) >52 degrees and no history of upper-extremity surgery, scoliosis, active shoulder pain, or shoulder pain in the previous 3 mo that restricted participation for 3 consecutive days. INTERVENTIONS: Photographic posture assessment under a control condition, under a sham or treatment condition (counterbalanced), under another control condition, and treatment or sham. MAIN OUTCOME MEASURES: FSA and forward head angle (FHA) calculated from a lateral photograph. RESULTS: FSA decreased relative to the control condition while participants wore the sham shirt (P = .029) but not the corrective posture shirt (P = 1.00). FHA was unchanged between groups (P = .371). CONCLUSIONS: Application of a corrective posture shirt did not acutely alter FSA or FHA, while application of a sham shirt may decrease FSA at rest.

PMID- 27705074 TI - Effects of the Addition of a Dual Task to a Supervised Physical Exercise Program on Older Adults' Cognitive Performance. AB - The purpose of this study was to investigate the effects of the addition of a dual task to multicomponent training on cognition of active older adults. Eighty physically active older adults were divided into an intervention group (IG) and a control group (CG). Both groups performed multicomponent training over 12 weeks. The IG simultaneously performed exercises and cognitive tasks. The Mini-Mental State Examination, the Montreal Cognitive Assessment, and the Clock Drawing Test were used for cognitive assessments. The Timed Up and Go Test associated with a cognitive task was used for dual-task assessment. Significant interactions were not observed between groups in terms of the cognitive variables or the dual-task performance. An interaction was observed only for Timed Up and Go Test performance, which was better in the CG than in the IG. Active older adults showed no improvement in cognition following the addition of the dual task to the multicomponent training. PMID- 27705075 TI - Electromyography Activation of the Lower-Limb Muscles Adopting a Physioball and Elastic Band to Stabilize the Knee Joint During Multiple Sets With Submaximal Loads. AB - STUDY DESIGN: Crossover design. CONTEXT: Excessive valgus and varus force which affected the knee joint during dynamic tasks has been often associated to lower extremity injuries. Strategies to increase the resistance against these asymmetries (eg, the use of a physioball between the knees or elastic bands around the knees) are often applied in rehabilitation and conditioning programs. OBJECTIVE: The purpose of this study was to investigate the effect of performing leg press (LP) 45 degrees using a physioball and elastic band over multiple sets with submaximal loads on electromyographic (EMG) amplitude and fatigue indices. METHODS: 18 trained females volunteered (age: 24.4 +/- 2.1 y; height: 168.1 +/- 4 cm; body mass: 65.1 +/- 4.4 kg) participated in this study. The 10 repetition maximum (RM) loads were determined for the LP. Then, 3 experimental protocols were followed in a randomized crossover design over 3 nonconsecutive days: control protocol-the participants performed 4 LP sets; physioball between knees-4 LP sets were performed with the physioball between the knees; elastic band-4 LP sets were performed with the elastic band involving the knees. Ten repetitions were performed during each set with 70% of 10-RM loads; EMG spectral indices (CRMS and Cf5) was collected from the biceps femoris (BF), vastus lateralis (VL), vastus medialis obliquus (VMO), and rectus femoris (RF) muscles. RESULTS: Higher levels of CRMS and Cf5 were noted for RF, VL, and VM muscles using the physioball and elastic band when compared with control protocol, respectively. CRMS index of BF muscle was significantly higher using physioball and elastic band protocol versus control condition, respectively. CONCLUSION: Therefore, both physioball and elastic band can be adopted during LP with the goal to reduce excessive varus and valgus forces, respectively, even performing consecutive sets with submaximal loads. Furthermore, this may be an interesting alternative to increasing quadriceps activation and improving the knee joint stabilization. PMID- 27705076 TI - Single-Task and Dual-Task Gait Among Collegiate Athletes of Different Sport Classifications: Implications for Concussion Management. AB - Gait impairments have been documented following sport-related concussion. Whether preexisting gait pattern differences exist among athletes who participate in different sport classifications, however, remains unclear. Dual-task gait examinations probe the simultaneous performance of everyday tasks (ie, walking and thinking), and can quantify gait performance using inertial sensors. The purpose of this study was to compare the single-task and dual-task gait performance of collision/contact and noncontact athletes. A group of collegiate athletes (n = 265) were tested before their season at 3 institutions (mean age= 19.1 +/- 1.1 years). All participants stood still (single-task standing) and walked while simultaneously completing a cognitive test (dual-task gait), and completed walking trials without the cognitive test (single-task gait). Spatial temporal gait parameters were compared between collision/contact and noncontact athletes using MANCOVAs; cognitive task performance was compared using ANCOVAs. No significant single-task or dual-task gait differences were found between collision/contact and noncontact athletes. Noncontact athletes demonstrated higher cognitive task accuracy during single-task standing (P = .001) and dual task gait conditions (P = .02) than collision/contact athletes. These data demonstrate the utility of a dual-task gait assessment outside of a laboratory and suggest that preinjury cognitive task performance during dual-tasks may differ between athletes of different sport classifications. PMID- 27705071 TI - Sarin (GB, O-isopropyl methylphosphonofluoridate) neurotoxicity: critical review. AB - Sarin (GB, O-isopropyl methylphosphonofluoridate) is a potent organophosphorus (OP) nerve agent that inhibits acetylcholinesterase (AChE) irreversibly. The subsequent build-up of acetylcholine (ACh) in the central nervous system (CNS) provokes seizures and, at sufficient doses, centrally-mediated respiratory arrest. Accumulation of ACh at peripheral autonomic synapses leads to peripheral signs of intoxication and overstimulation of the muscarinic and nicotinic receptors, which is described as "cholinergic crisis" (i.e. diarrhea, sweating, salivation, miosis, bronchoconstriction). Exposure to high doses of sarin can result in tremors, seizures, and hypothermia. More seriously, build-up of ACh at neuromuscular junctions also can cause paralysis and ultimately peripherally mediated respiratory arrest which can lead to death via respiratory failure. In addition to its primary action on the cholinergic system, sarin possesses other indirect effects. These involve the activation of several neurotransmitters including gamma-amino-butyric acid (GABA) and the alteration of other signaling systems such as ion channels, cell adhesion molecules, and inflammatory regulators. Sarin exposure is associated with symptoms of organophosphate-induced delayed neurotoxicity (OPIDN) and organophosphate-induced chronic neurotoxicity (OPICN). Moreover, sarin has been involved in toxic and immunotoxic effects as well as organophosphate-induced endocrine disruption (OPIED). The standard treatment for sarin-like nerve agent exposure is post-exposure injection of atropine, a muscarinic receptor antagonist, accompanied by an oxime, an AChE reactivator, and diazepam.

PMID- 27705078 TI - Changes in Thiol-Disulfide Homeostasis of the Body to Surgical Trauma in Laparoscopic Cholecystectomy Patients. AB - OBJECTIVE: We aimed to investigate the short-term effect of laparoscopic surgery on serum thiol-disulfide homeostasis levels as a marker of oxidant stress of surgical trauma in elective laparoscopic cholecystectomy patients. MATERIALS AND METHODS: Venous blood samples were collected, and levels of native thiols, total thiols, and disulfides were determined with a novel automated assay. Total antioxidant capacity (measured as the ferric-reducing ability of plasma) and serum ischemia modified albumin, expressed as absorbance units assayed by the albumin cobalt binding test, were determined. RESULTS: The major findings of the present study were that native thiol (283 +/- 45 versus 241 +/- 61 MUmol/L), total thiol (313 +/- 49 versus 263 +/- 67 MUmol/L), and disulfide (14.9 +/- 4.6 versus 11.0 +/- 6.1 MUmol/L) levels were decreased significantly during operation and although they increased, they did not return to preoperation levels 24 hours after laparoscopic surgery compared to the levels at baseline. Disulfide/native thiol and disulfide/total thiol levels did not change during laparoscopic surgery. CONCLUSIONS: The decrease in plasma level of native and total thiol groups suggests impairment of the antioxidant capacity of plasma; however, the delicate balance between the different redox forms of thiols was maintained during surgery. PMID- 27705079 TI - Gender Differences in Outpatient Utilization: A Pooled Analysis of Data from the Korea Health Panel. AB - BACKGROUND: This study aims to set itself apart from prior research by elucidating gender differences in outpatient service utilization among adults aged 20 years or older, using nationally representative survey data. METHODS: Data from the Korea Health Panel (KHP) collected between 2010 and 2011 were used. In this study, all KHP participants who accessed outpatient service between 2010 and 2011 were included; 13,525 participants used outpatient services in 2010 and 12,991 in 2011. To analyze factors related to outpatient utilization, regression analysis was performed using generalized estimating equations. RESULTS: The use frequency of outpatient service was significantly associated with age, education level, marital status, economic activity, health insurance status, drinking, presence of chronic disease, and self-rated health status in both sexes (p < 0.05). Annual household income significantly affected outpatient utilization only among women. CONCLUSIONS: Unlike males, females with higher household incomes used outpatient services more. This suggests that females are at greater risk of medical inequality based on economic circumstances. PMID- 27705080 TI - Generation of Pax1/PAX1-Specific Monoclonal Antibodies. AB - Pax genes encode an evolutionary conserved group of transcription factors with multiple roles during embryonic development and for cell type specification in normal and malignant tissues of the adult organism. In mice, Pax1 is required for the formation of specific skeletal structures as well as for the development of a fully functional thymus. In humans, the PAX1 locus has been linked to otofaciocervical syndrome, idiopathic scoliosis, and to a higher susceptibility for androgenic alopecia. In addition, the methylation status of PAX1 has recently emerged as a sensitive marker for predictive screening of cervical cancer. To provide a reagent for reproducible detection of Pax1 expression, we have generated rat monoclonal antibodies (MAbs) against the murine Pax1 protein. MAbs of one clone (clone 5A2) specifically detect mouse Pax1 protein in Western blot analyses. Moreover, the anti-Pax1 MAbs cross-react with human PAX1 protein and are applicable in immunohistochemical detection procedures using paraformaldehyde/formalin-fixed tissues embedded in paraffin. The anti-Pax1 MAbs provide a reliable reagent for reproducible Pax1/PAX1 protein expression analyses and, therefore, may help to improve diagnostic protocols in clinical settings involving deregulated expression of Pax1/PAX1. PMID- 27705081 TI - Approach to Recurrent Congenital Diaphragmatic Hernia: Results of an International Survey. AB - PURPOSE: Although recurrence remains one of the most feared complications following congenital diaphragmatic hernia (CDH) repair, there are minimal data on the optimal surgical approach to these complex situations. The purpose of this study was to survey the international pediatric surgery community to ascertain practice patterns for both minimally invasive (MIS) and open approaches for recurrent CDH. MATERIALS AND METHODS: A survey was e-mailed to members of an online community of pediatric surgeons. The questionnaire elicited surgeons' clinical experience, the continent in which they practice, and their surgical approach (laparotomy, thoracotomy, laparoscopy, or thoracoscopy) to five clinical cases, including initial and recurrent Bochdalek hernias. Fisher's exact test and chi-square test were used for statistical analysis. RESULTS: Two-hundred eighty pediatric surgeons responded to the survey. In total, 52.1% of surgeons chose an MIS approach for an initial repair of left CDH with the younger surgeons more likely to use an MIS approach. For the recurrence scenarios, 42.5%-55.5% of these surgeons would attempt an MIS repair after a recurrence. Specifically, thoracoscopy was favored over laparoscopy following both prior laparotomy (30.0% versus 7.5%) and prior right thoracoscopy (26.4% versus 10.0%), less favored following thoracotomy (9.3% versus 18.9%), and relatively similar proportions following prior left thoracoscopy (17.5% versus 16.4%). Laparotomy was the preferred open approach both for initial presentation and all recurrence scenarios. Among surgeons who would treat initial CDH with an open procedure, between 10.4% and 17.9% would switch to an MIS approach, most commonly after prior failed laparotomy. CONCLUSIONS: Approximately half surgeons who approach initial left CDH in an MIS manner would attempt an MIS approach for recurrence. The tendency to approach CDH recurrence from the opposite body cavity as the initial repair clearly impacted the surgical approach. This was particularly pronounced for MIS repairs, whereas for open approach, laparotomy remained, by far, the most popular in all scenarios. PMID- 27705082 TI - Is Single-Port Laparoscopy More Precise and Faster with the Robot? AB - BACKGROUND: Single-port laparoscopy is a step forward toward nearly scar less surgery. Concern has been raised that single-incision laparoscopic surgery (SILS) is technically more challenging because of the lack of triangulation and the clashing of instruments. Robotic single-incision laparoscopic surgery (RSILS) in chopstick setting might overcome these problems. This study evaluated the outcome in time and errors of two tasks of the Fundamentals of Laparoscopic Surgery on a dry platform, in two settings: SILS versus RSILS. METHODS: Nine experienced laparoscopic surgeons performed two tasks: peg transfer and a suturing task, on a standard box trainer. All participants practiced each task three times in both settings: SILS and a RSILS setting. The assessment scores (time and errors) were recorded. RESULTS: For the first task of peg transfer, RSILS was significantly better in time (124 versus 230 seconds, P = .0004) and errors (0.80 errors versus 2.60 errors, P = .024) at the first run, compared to the SILS setting. At the third and final run, RSILS still proved to be significantly better in errors (0.10 errors versus 0.80 errors, P = .025) compared to the SILS group. RSILS was faster in the third run, but not significant (116 versus 157 seconds, P = .08). For the second task, a suturing task, only 3 participants of the SILS group were able to perform this task within the set time frame of 600 seconds. There was no significant difference in time in the three runs between SILS and RSILS for the 3 participants that fulfilled both tasks within the 600 seconds. CONCLUSIONS: This study shows that robotic single-port surgery seems easier, faster, and more precise to perform basis tasks of the Fundamentals of laparoscopic surgery. For the more complex task of suturing, only the single-port robotic setting enabled all participants to fulfill this task, within the set time frame. PMID- 27705083 TI - Comparing High Definition Live Interactive and Store-and-Forward Consultations to In-Person Examinations. AB - BACKGROUND: There is little teledermatology research directly comparing remote methods, even less research with two in-person dermatologist agreement providing a baseline for comparing remote methods, and no research using high definition video as a live interactive method. OBJECTIVE: To compare in-person consultations with store-and-forward and live interactive methods, the latter having two levels of image quality. METHODS: A controlled study was conducted where patients were examined in-person, by high definition video, and by store-and-forward methods. The order patients experienced methods and residents assigned methods rotated, although an attending always saw patients in-person. The type of high definition video employed, lower resolution compressed or higher resolution uncompressed, was alternated between clinics. Primary and differential diagnoses, biopsy recommendations, and diagnostic and biopsy confidence ratings were recorded. RESULTS: Concordance and confidence were significantly better for in-person versus remote methods and biopsy recommendations were lower. Store-and-forward and higher resolution uncompressed video results were similar and better than those for lower resolution compressed video. LIMITATIONS: Dermatology residents took store-and-forward photos and their quality was likely superior to those normally taken in practice. There were variations in expertise between the attending and second and third year residents. CONCLUSION: The superiority of in person consultations suggests the tendencies to order more biopsies or still see patients in-person are often justified in teledermatology and that high resolution uncompressed video can close the resolution gap between store-and forward and live interactive methods. PMID- 27705084 TI - Levosimendan for the Prevention of Acute Organ Dysfunction in Sepsis. AB - BACKGROUND: Levosimendan is a calcium-sensitizing drug with inotropic and other properties that may improve outcomes in patients with sepsis. METHODS: We conducted a double-blind, randomized clinical trial to investigate whether levosimendan reduces the severity of organ dysfunction in adults with sepsis. Patients were randomly assigned to receive a blinded infusion of levosimendan (at a dose of 0.05 to 0.2 MUg per kilogram of body weight per minute) for 24 hours or placebo in addition to standard care. The primary outcome was the mean daily Sequential Organ Failure Assessment (SOFA) score in the intensive care unit up to day 28 (scores for each of five systems range from 0 to 4, with higher scores indicating more severe dysfunction; maximum score, 20). Secondary outcomes included 28-day mortality, time to weaning from mechanical ventilation, and adverse events. RESULTS: The trial recruited 516 patients; 259 were assigned to receive levosimendan and 257 to receive placebo. There was no significant difference in the mean (+/-SD) SOFA score between the levosimendan group and the placebo group (6.68+/-3.96 vs. 6.06+/-3.89; mean difference, 0.61; 95% confidence interval [CI], -0.07 to 1.29; P=0.053). Mortality at 28 days was 34.5% in the levosimendan group and 30.9% in the placebo group (absolute difference, 3.6 percentage points; 95% CI, -4.5 to 11.7; P=0.43). Among patients requiring ventilation at baseline, those in the levosimendan group were less likely than those in the placebo group to be successfully weaned from mechanical ventilation over the period of 28 days (hazard ratio, 0.77; 95% CI, 0.60 to 0.97; P=0.03). More patients in the levosimendan group than in the placebo group had supraventricular tachyarrhythmia (3.1% vs. 0.4%; absolute difference, 2.7 percentage points; 95% CI, 0.1 to 5.3; P=0.04). CONCLUSIONS: The addition of levosimendan to standard treatment in adults with sepsis was not associated with less severe organ dysfunction or lower mortality. Levosimendan was associated with a lower likelihood of successful weaning from mechanical ventilation and a higher risk of supraventricular tachyarrhythmia.

PMID- 27705085 TI - The Onset of Intra-Abdominal Adhesions During Closed-Abdomen Hyperthermic Intraperitoneal Chemotherapy. AB - INTRODUCTION: Hyperthermic intraperitoneal chemotherapy (HIPEC) is delivered after cytoreductive surgery (CRS) in selected patients with peritoneal carcinomatosis. The closed-abdomen technique, preferred by many centers, prevents heat loss and drug spillage, but does not warrant homogeneous distribution of the perfusion fluid (PF). The hypothesized formation of intra-abdominal adhesions during the closed-abdomen perfusion period has never been described. MATERIALS AND METHODS: From March 2014 to April 2016, 10 consecutive patients with peritoneal carcinomatosis, selected for CRS, underwent the Laparoscopy-Enhanced HIPEC technique to explore the abdominal cavity during the perfusion. The aim of the study was to investigate the incidence and the extent of intra-abdominal adhesions that are formed after CRS during the perfusion period of closed-abdomen HIPEC. RESULTS: During the perfusion, adhesions developed in 70% of the patients. Adhesions developed mainly in the period between the closure of the abdomen and the subsequent filling of the abdomen with the PF. After their first division, during the following perfusion period, adhesions between the bowel and the abdominal wall reformed in 3 patients (30%). CONCLUSIONS: Intra-abdominal adhesions are frequently formed during closed-abdomen HIPEC and can hamper the adequate circulation of the PF. The Laparoscopy-Enhanced technique enables the early detection and the division of any intra-abdominal adhesions. PMID- 27705086 TI - Transdiagnostic group CBT for anxiety disorders: the unified protocol in mental health services. AB - Comorbidity among the anxiety disorders is common and may negatively impact treatment outcome. Potentially, transdiagnostic cognitive-behavioral treatments (CBT) deal more effectively with comorbidity than standard CBT. The present study tested the effectiveness of The Unified Protocol (UP) applied to Mental Health Services. Pre-post-treatment effects were examined for psychiatric outpatients with anxiety disorders receiving UP treatment in groups. Forty-seven patients (mean-age = 34.1 (SD = 9.92), 77% females) with a principal diagnosis of anxiety were included. We found significant and clinically meaningful changes in the primary outcomes Clinical Global Impression Severity Scale (CGI-S; d = 1.36), Hamilton Anxiety Scale (HARS; d = .71), and WHO-5 Well-being Index (WHO-5; d = .54). Also, comorbid depressive symptoms and levels of positive and negative affect changed significantly after treatment. Patients with high levels of comorbidity profited as much as patients with less comorbidity; however, these patients had higher scores after treatment due to higher symptom burden at onset. Patients with comorbid depression profited more from treatment than patients without comorbid depression. The treatment effects found in the present study correspond to treatment effects of other TCBT studies, other UP group studies, and effectiveness studies on standard CBT for outpatients. The results indicate that the UP can be successfully applied to a MHS group setting, demonstrating positive effects on anxiety and depressive symptoms for even highly comorbid cases. PMID- 27705087 TI - Measurement of neurodevelopmental changes in children treated with radiation for brain tumors: what is a true 'baseline?' AB - OBJECTIVE: To review the various ways in which baseline neuropsychological functioning is measured in the extant literature on pediatric brain tumors, describe the pros and cons of each approach, and increase the awareness of researchers as to the implications of each. METHOD: We reviewed the literature from 1993 to 2013, and classified studies by baseline approach and explicitness of selection of approach. RESULTS: There are multiple approaches to operationalizing baseline levels of ability and to assess change from baseline. Each approach has strengths and weaknesses, and selection may depend on the question under investigation. Approaches to baseline estimation varied widely with a trend over time toward reliance on statistical modeling. Researchers were often insufficiently explicit about the reasons for adopting a particular approach. The common use of standardized scores requires caution as they obscure critical inferential limitations about change and magnitude of change. Some viable approaches were infrequently used, such as actuarial prediction formulas. Multiple simultaneous methods akin to theory testing and formal methods of construct validation could enhance scientific yield since all approaches are fallible. CONCLUSIONS: Estimating baseline neuropsychological functioning is very challenging, particularly when it concerns children in the preschool years. Nevertheless, it is a crucial methodological decision with important implications for the interpretation of research findings that needs to be dealt with explicitly. PMID- 27705088 TI - Thoracoscopic Lobectomy in Infants and Children Utilizing a 5 mm Stapling Device. AB - PURPOSE: Thoracoscopic lobectomy for congenital cystic lung disease has become an accepted and in many institutions the preferred technique. However, the technical challenges are many. Previous endoscopic staplers (12 mm) used commonly in adults are too large for use in infants This study evaluates the safety and efficacy of using a 5 mm stapling device to seal and divide major pulmonary structures. METHODS: From July 2014 to March 2016, 26 patients of age 6 weeks to 13 months underwent thoracoscopic lobectomy for CPAM or sequestration. Weights ranged from 3.2 to 11.4 kg. There were 7 upper lobectomies, 2 middle, and 17 lower lobectomies. In each case, the 5 mm stapler (Justright Surgical; Louisville, Colorado) was the primary device for vessel and bronchial sealing and division. It is 4.8 mm in diameter with an anvil length of 25 mm and lays down four rows of staples and divides between them. A 3 mm sealing device was used for dissection and to take smaller segmental vessels as necessary. Stump lines were evaluated for bleeding or air leak in all cases. RESULTS: All procedures were accomplished successfully thoracoscopically. The stapler was used on the main lobar artery cases and vein in 24 cases, a large systemic sequestration vessel in 5 cases, and the bronchus in all 26. The stapler was also used to complete the minor fissure in 1 case and the major fissure in 1 case. A total of 96 staple loads were fired. Operative times ranged from 35 to 135 minutes. There was no significant bleeding of any vascular stump. In 1 case, the edge of the bronchial stump had to be reinforced, this was thought to be secondary to too much tissue being enclosed in the jaws. There were no postoperative complications. CONCLUSION: The use of a 5 mm stapling device appears to be safe and effective in thoracoscopic lobectomy in infants. It allows for safe management of major pulmonary vessels and bronchi in the confined chest of an infant through a single 5 mm port. PMID- 27705089 TI - Drug Initiation of Female Detainees in a Compulsory Drug Treatment Institution in China. AB - This study explored drug initiation among 46 Chinese women in a compulsory drug treatment institution. The study adopted a mixed method with a strong emphasis on qualitative techniques to capture the perspectives of women in long-term treatment regarding their drug initiation experiences. A complementary analysis of quantitative data was used to help interpret, refine, deepen, and extend qualitative findings. Participants were divided into two groups according to their main drug of choice: 27 used methamphetamines and 19 used heroin (11 of them used methamphetamines occasionally). Four main themes were identified in the analysis of participants' drug initiation narratives: (1) involvement in high risk social networks; (2) lack of family love and support; (3) relationship problems; and (4) male partner influence. Findings indicate that the younger generation preferred starting their drug career with methamphetamines rather than heroin, due to the changes in the drug market and broader changes related to globalization. A lack of family love and support had a strong effect on the initiation of methamphetamine but not heroin users; however, male intimate partners and relationship issues showed strong influence on heroin initiation. Having high-risk social networks was a common narrative in the drug use initiation of Chinese women across methamphetamine and heroin groups.

AB - Confabulation may be present in Alzheimer's disease (AD), but usually it is not a primary feature of either its typical or atypical variants. In this report, we describe the case of an AD patient who showed an unusual and enduring neuropsychiatric phenotype characterized by early and prominent spontaneous confabulation. Surprisingly, such atypical AD presentation bears a striking resemblance to presbyophrenia, a subtype of dementia which was described at the beginning of the twentieth century and then sank into oblivion. In discussion, we speculate on the "return" of presbyophrenia as an unrecognized neuropsychiatric variant of AD and its possible neuroanatomical substrates. PMID- 27705091 TI - Guillain-Barre Syndrome Associated with Zika Virus Infection in Colombia. AB - BACKGROUND: Zika virus (ZIKV) infection has been linked to the Guillain-Barre syndrome. From November 2015 through March 2016, clusters of cases of the Guillain-Barre syndrome were observed during the outbreak of ZIKV infection in Colombia. We characterized the clinical features of cases of Guillain-Barre syndrome in the context of this ZIKV infection outbreak and investigated their relationship with ZIKV infection. METHODS: A total of 68 patients with the Guillain-Barre syndrome at six Colombian hospitals were evaluated clinically, and virologic studies were completed for 42 of the patients. We performed reverse transcriptase-polymerase-chain-reaction (RT-PCR) assays for ZIKV in blood, cerebrospinal fluid, and urine, as well as antiflavivirus antibody assays. RESULTS: A total of 66 patients (97%) had symptoms compatible with ZIKV infection before the onset of the Guillain-Barre syndrome. The median period between the onset of symptoms of ZIKV infection and symptoms of the Guillain-Barre syndrome was 7 days (interquartile range, 3 to 10). Among the 68 patients with the Guillain-Barre syndrome, 50% were found to have bilateral facial paralysis on examination. Among 46 patients in whom nerve-conduction studies and electromyography were performed, the results in 36 patients (78%) were consistent with the acute inflammatory demyelinating polyneuropathy subtype of the Guillain Barre syndrome. Among the 42 patients who had samples tested for ZIKV by RT-PCR, the results were positive in 17 patients (40%). Most of the positive RT-PCR results were in urine samples (in 16 of the 17 patients with positive RT-PCR results), although 3 samples of cerebrospinal fluid were also positive. In 18 of 42 patients (43%) with the Guillain-Barre syndrome who underwent laboratory testing, the presence of ZIKV infection was supported by clinical and immunologic findings. In 20 of these 42 patients (48%), the Guillain-Barre syndrome had a parainfectious onset. All patients tested were negative for dengue virus infection as assessed by RT-PCR. CONCLUSIONS: The evidence of ZIKV infection documented by RT-PCR among patients with the Guillain-Barre syndrome during the outbreak of ZIKV infection in Colombia lends support to the role of the infection in the development of the Guillain-Barre syndrome.

AB - This study determined the relationship between self-reported and objective measurements of physical activity with adiposity markers in a random sample of community-dwelling older adults. The sample included 439 individuals over 65 years (age 71.1 +/- 7.8; 54.2% women). Regular physical activity information was collected using self-reported (questionnaire, 7-day-PAR) and objective measurements (accelerometer ActiGraph GT3X) over 7 days. Anthropometric parameters included body mass index, body fat percentage, and waist circumference. The number of patients considered active was 28% according to the results of 7-day PAR, and 69% according to objective measures of accelerometry. With every daily increase of 10 min of sedentary activity, the BMI, body fat percentage, and waist circumference values increased by 0.04 units, 0.14%, and 0.14 cm, respectively. According to the accelerometry data, being active was a protective factor for presenting obesity criteria (OR = 0.34, CI 95% 0.19-0.59). Objective but non self-reported physical activity was associated with adiposity markers in older adults. PMID- 27705092 TI - An fMRI study on the comparison of different types of false belief reasoning: False belief-based emotion and behavior attribution. AB - False belief (FB) reasoning is a key Theory of Mind (ToM) competence. By 4 years of age, children understand that a person's behavior can be based on a FB about reality. Children cannot understand that a person's emotion can also be based on a FB before the age of six. In order to generate hypothesis on basic processes distinguishing these two types of belief reasoning, the present functional magnetic resonance imaging study in adults directly compares functional activity associated with these two FB tasks. Both tasks were associated with activity in the ToM network including the medial prefrontal cortex and the left temporo parietal junction. Differential activity was observed in the anterior dorsolateral prefrontal cortex for FB-based emotion relative to behavior attribution. Contrary to FB behavior attribution, FB-based emotion attribution requires the processing of two different mental states: a belief and an emotion and their relation to each other. The activity pattern may reflect the differential demands on cognitive processes associated with the two different belief-based attribution processes. These results shed new light on the still ongoing debate about the nature of the developmental lag between the two FB tasks. PMID- 27705094 TI - Population Health Measurement at Centers for Medicare & Medicaid Services: Bridging the Gap Between Public Health and Clinical Quality. AB - As Medicare and Medicaid increasingly shift to alternative payment models focused on population-based payments, there is an urgent need to develop measures of population health that can drive health improvement. In response, an assessment and design project established a framework for developing population health measures from a payer perspective, conducted environmental scans of existing measures and available data infrastructure, and conducted a gap analysis informing measure development and infrastructure needs. The work, summarized here, makes recommendations for creating a set of core measures, demonstrates some of the key challenges in applying a traditional quality measure development framework to population health, and complements recent efforts by the National Academy of Medicine and others with a focus on a payer perspective. PMID- 27705095 TI - Telerehabilitation in Stroke Recovery: A Survey on Access and Willingness to Use Low-Cost Consumer Technologies. AB - : Background/Introduction: Early telerehabilitation trials with stroke survivors have shown promising results, but there remains a lack of knowledge of what areas of rehabilitation people with stroke are interested and willing to receive using technology. The purpose of this study was to describe the access to low-cost consumer technologies and willingness to use them to receive rehabilitation services among stroke survivors. MATERIALS AND METHODS: Participants were included in this survey study if they had a stroke, lived in the community, were 19 years of age or older, and able to understand English. Participants completed a study-specific telerehabilitation survey via phone call, mail, in-person, or online. Descriptive statistics were used to characterize the sample and survey responses. RESULTS: One hundred two survey responses were returned, representing a 79.1% response rate. The mean age of this urban (67.3%) and rural (32.7%) sample was 67.6 years. The technologies most commonly owned were as follows: televisions (91%), landline telephones (88.0%), and computers (79.0%). A large proportion of the sample reported an interest to receive assessments (58.4%), training and exercise programs (64.0%), and education (61.4%) via telerehabilitation, however, many were not interested to receive telerehabilitation (~39%) and believed that the quality of care would be less than in-person rehabilitation (71.0%). CONCLUSIONS: The use of consumer technologies for the delivery of rehabilitation services is both feasible and desirable by stroke survivors. Telerehabilitation services at present should augment and not replace in-person rehabilitation. However, in cases where in person rehabilitation is neither accessible nor possible, telerehabilitation could serve as an acceptable alternative and is a key area for future research. PMID- 27705096 TI - The Occurrence of Trichinella spp. in Red Foxes (Vulpes vulpes) in Different Regions of Poland: Current Data. AB - Trichinellosis is one of the most widespread parasitic zoonoses. Trichinella Owen, 1835 nematodes are found in pigs, horses, and humans in the domestic cycle, and in many carnivores and omnivores in the sylvatic cycle, such as wild boars, red foxes, raccoon dogs, and wolves. Carnivores are known to be involved in the circulation of Trichinella nematodes and they act as a reservoir in the sylvatic environment. The aim of this study was to determine the occurrence of Trichinella spp. infection in red foxes in Poland. Samples were collected from 2010 to 2015 in different regions of the country and then tested for Trichinella nematodes using HCl-pepsin digestion. Trichinella larvae were found in 10.02% of examined samples (145/1447). The larvae were identified as T. spiralis (11.03%), T. britovi (71.72%), and T. pseudospiralis (0.69%). No mixed infection was observed. The prevalence of infection varied between years and different voivodeships of the country. Our findings confirm that red foxes are involved in the maintenance of Trichinella spp. in the sylvatic cycle in Poland. PMID- 27705097 TI - A Comparative Study on the Transareola Single-Site Versus Three-Port Endoscopic Thyroidectomy. AB - OBJECTIVE: To explore the feasibility, safety, and advantages of transareola single-site endoscopic thyroidectomy. METHODS: From January 2014 to December 2015, 40 patients were randomly divided into an observation group who received single-site endoscopic thyroidectomy by the areola approach and a control group who underwent three-port endoscopic thyroidectomy by the areola approach with 20 patients in each group. The feasibility and safety of the operation and postoperative clinical outcomes were compared between these two groups. RESULTS: There was no significant difference in operation time, intraoperative blood loss, and hospitalization time (P > .05) between the two groups. The subcutaneous dissection area in the observation group (130 [120-130] cm2) was significantly smaller than that in the control group (180 [170-190] cm2) (P < .01). In addition, there is much less postoperative drainage in the observation group (70 [50-80] mL) than in the control group (80 [60-100] mL) (P = .036). Furthermore, 24-hour postoperative pain score in the observation group (4.0 [3.0-5.5]) was significantly lower compared with that in the control group (5.0 [4.0-7.0]) (P = .047). Moreover, patients in the observation group present with significantly higher 7-day postoperative cosmetic satisfaction scores (9.0 [8.0-9.0]) than those in the control group (7.0 [7.0-8.0]) (P < .001). CONCLUSION: Transareola single-site endoscopic thyroidectomy exhibits superior advantages in clinical outcomes such as causing less pain and achieving better cosmetic satisfaction, compared with three-port endoscopic thyroidectomy.

PMID- 27705102 TI - Toxoplasmatinae Parasites in Bats from Bahia State, Brazil. AB - Toxoplasma gondii and Neospora caninum are widespread cyst-forming coccidian parasites of the subfamily Toxoplasmatinae that infect a wide range of wild and domestic animals. Whereas T. gondii is a zoonotic disease, N. caninum is restricted to nonhuman animals. Some chiropteran species can be infected by T. gondii and present fatal toxoplasmosis. In most cases, T. gondii -infected bats are believed to remain asymptomatic and to act as an infection source to other animals. It is not known whether N. caninum can infect bats. We determined infection rates of T. gondii and N. caninum in free-living bats in the state of Bahia, Brazil. Brain samples from 97 bats of seven species, captured in 2008-15, were analyzed by PCRs for T. gondii and N. caninum . Two of the 97 samples were positive for T. gondii DNA. None of the samples were positive for N. caninum DNA, suggesting that the bats were not susceptible to N. caninum infection or that its prevalence was very low. PMID- 27705101 TI - Chemical Restraint of Free-ranging South American Coatis ( Nasua nasua ) with a Combination of Tiletamine and Zolazepam. AB - We describe the use of a combination of tiletamine and zolazepam (Zoletil(r)) for chemical restraint of South American coatis ( Nasua nasua ) under field conditions. We immobilized 53 coatis from a free-ranging population at Iguacu National Park, Brazil, with Zoletil. Males and females (1.0-8.7 kg) of different age groups participated in the study. Four dosage (milligram per kilogram body weight) groups were created based on quartiles as follows: 1) 4.76-6.68 mg/kg (n=13), 2) 6.83-7.71 mg/kg (n=13), 3) 7.72-8.68 mg/kg (n=18), and 4) 8.98-11.57 mg/kg (n=9). Variables analyzed were sex, age, body weight, dosage, induction time, handling time (HT: time elapsed between the onset of immobilization and first signs of recovery), time from injection to first stand-up posture after anesthesia, heart and respiratory rates, and body temperature. Mean (+/-SD) induction time was 2.9 (+/-1.4) min and was positively correlated with age. In dosage groups 1-4, mean HTs were 40.3 (+/-24.0), 64.5 (+/-19.1), 54.8 (+/-15.0), and 60.3 (+/-12.0), respectively. Handling time had a positive linear relationship with age and body weight, but the relationship between HT and dosage was nonlinear. Group 1 had a shorter HT compared to the other groups combined. Time from injection to first stand-up was 105.0 (+/-33.5) min. Zoletil was quick acting and safe for immobilization of coatis in the wild. PMID- 27705103 TI - RETROSPECTIVE ANALYSIS OF THE EPIDEMIOLOGIC LITERATURE, 1990-2015, ON WILDLIFE ASSOCIATED DISEASES FROM THE REPUBLIC OF KOREA. AB - To assess the status of research on wildlife diseases in the Republic of Korea (ROK) and to identify trends, knowledge gaps, and directions for future research, we reviewed epidemiologic publications on wildlife-associated diseases in the ROK. We identified a relatively small but rapidly increasing body of literature. The majority of publications were focused on public or livestock health and relatively few addressed wildlife health. Most studies that focused on human and livestock health were cross-sectional whereas wildlife health studies were mostly case reports. Fifteen diseases notifiable to the World Organisation for Animal Health were identified and 21 diseases were identified as notifiable to either the Korea Ministry of Health and Welfare or the Korea Ministry of Agriculture, Food and Rural Affairs. Two diseases were reported as occurring as epidemics; highly pathogenic avian influenza (HPAI) and virulent Newcastle disease. Six diseases or disease agents were described in the literature as emerging including HPAI, rabies, Babesia microti , avian coronaviruses, scrub typhus, and severe fever thrombocytopenia syndrome virus. The diseases for which there were the largest number of publications were HPAI and rabies. The majority of wildlife associated zoonotic disease publications focused on food-borne parasitic infections or rodent-associated diseases. Several publications focused on the potential of wildlife as reservoirs of livestock diseases; in particular, Korean water deer ( Hydropotes inermis argyropus ) and wild boar ( Sus scrofa ). In contrast, there were few publications on diseases of concern for wildlife populations or research to understand the impacts of these diseases for wildlife management. Increased focus on prospective studies would enhance understanding of disease dynamics in wildlife populations. For the high-consequence diseases that impact multiple sectors, a One Health approach, with coordination among the public health, agricultural, and environmental sectors, would be important. This type of review can provide useful information for countries or regions planning or implementing national wildlife health programs. PMID- 27705104 TI - A Serosurvey of Greater Sage-Grouse ( Centrocercus urophasianus ) in Nevada, USA. AB - To better understand the potential avian diseases in Greater Sage-grouse ( Centrocercus urophasianus ) in the Great Basin in Nevada, US, we collected 31 blood samples March-April 2014 and tested for antibodies to eight viruses and two bacteria. Specifically, sera were tested for antibodies to avian leukosis virus type A, B, and J (ALV-A, ALV-B, and ALV-J, respectively), infectious bursal disease virus, infectious bronchitis virus, reticuloendothelial virus, avian influenza virus (AIV), West Nile virus, Pasteurella multocida (PM), and Salmonella enterica serovar Pullorum. Serum antibodies against ALV-A and -B (1/31, 3%), ALV-J (5/31, 16%), PM (1/31, 3%), and AIV (2/31, 6%) were detected by enzyme-linked immunosorbent assay (ELISA). While ELISA tests used have only been validated in domestic poultry, the serologic data should be used as a potential indicator of the range of bacterial and viral infectious agents that can infect the Greater Sage-grouse. PMID- 27705181 TI - Birth at 22 gestational weeks: case report of cognitive resilience. AB - OBJECTIVE: Children delivered at the edge of viability are at greatest risk of medical and neuropsychological disability, their adverse outcomes overshadowing extremely preterm survivors with more optimal outcomes. We aimed to describe an exceptionally early-born extremely preterm (EEEP) preschooler whose neurobiological, familial, and socioeconomic factors likely influenced her unexpected cognitive resilience. METHOD: Baby G was a 3-years 10-months-old, English-speaking, Caucasian, singleton girl born weighing 435 g at 225/7 weeks' gestation to well-educated married parents. Neonatal complications of extremely premature birth included sepsis, severe respiratory distress syndrome, patent ductus arteriosus requiring ligation, necrotizing enterocolitis not requiring surgical intervention, and retinopathy of prematurity. Intellectual and neuropsychological testing was administered. RESULTS: Baby G performed age appropriately in nearly all domains and did not exhibit intellectual deficits. Her general conceptual ability was above average for both her chronological and adjusted ages. She had below average performance on tests of motor function, working memory, and delayed recall of spatial locations. Standardized parental behavioral questionnaires indicated no concern in emotional or attentional functioning except in relation to mental shifting capacity and signs of anxiety. CONCLUSION: Report of persistent adverse neurodevelopmental/neuropsychological disabilities following EEEP birth is a counterpoint to the more optimal outcomes in some vulnerable EEEP survivors. This case emphasizes that decisions about aggressive resuscitation and prognostication for infants born EEEP may be enhanced by consideration of individual variability, and of pertinent medical, socioeconomic, and sociodemographic variables that may be more predictive of neuropsychological outcomes than birth weight and gestational age.

AB - OBJECTIVE: Characterization of academic functioning in children with autism spectrum disorder (ASD), particularly predictors of achievement, may have important implications for intervention. The current study aimed to characterize achievement profiles, confirm associations between academic ability and concurrent intellectual and social skills, and explore preschool predictors of school-age academic achievement in a sample of children with ASD. METHOD: Children with ASD (n = 26) were evaluated at the approximate ages of two, four, and ten. Multiple regression was used to predict school-age academic achievement in reading and mathematics from both concurrent (i.e. school-age) and preschool variables. RESULTS: Children with ASD demonstrated a weakness in reading comprehension relative to word reading. There was a smaller difference between mathematics skills; math reasoning was lower than numerical operations, but this did not quite reach trend level significance. Concurrent IQ and social skills were associated with school-age academic achievement across domains. Preschool verbal abilities significantly predicted school-age reading comprehension, above and beyond concurrent IQ, and early motor functioning predicted later math skills. CONCLUSIONS: Specific developmental features of early ASD predict specific aspects of school-age achievement. Early intervention targeting language and motor skills may improve later achievement in this population. PMID- 27705184 TI - ? PMID- 27705186 TI - ? PMID- 27705185 TI - ? PMID- 27705187 TI - ?

PMID- 27705249 TI - Life Expectancy after Myocardial Infarction, According to Hospital Performance. AB - BACKGROUND: Thirty-day risk-standardized mortality rates after acute myocardial infarction are commonly used to evaluate and compare hospital performance. However, it is not known whether differences among hospitals in the early survival of patients with acute myocardial infarction are associated with differences in long-term survival. METHODS: We analyzed data from the Cooperative Cardiovascular Project, a study of Medicare beneficiaries who were hospitalized for acute myocardial infarction between 1994 and 1996 and who had 17 years of follow-up. We grouped hospitals into five strata that were based on case-mix severity. Within each case-mix stratum, we compared life expectancy among patients admitted to high-performing hospitals with life expectancy among patients admitted to low-performing hospitals. Hospital performance was defined by quintiles of 30-day risk-standardized mortality rates. Cox proportional hazards models were used to calculate life expectancy. RESULTS: The study sample included 119,735 patients with acute myocardial infarction who were admitted to 1824 hospitals. Within each case-mix stratum, survival curves of the patients admitted to hospitals in each risk-standardized mortality rate quintile separated within the first 30 days and then remained parallel over 17 years of follow-up. Estimated life expectancy declined as hospital risk-standardized mortality rate quintile increased. On average, patients treated at high-performing hospitals lived between 0.74 and 1.14 years longer, depending on hospital case mix, than patients treated at low-performing hospitals. When 30-day survivors were examined separately, there was no significant difference in unadjusted or adjusted life expectancy across hospital risk-standardized mortality rate quintiles. CONCLUSIONS: In this study, patients admitted to high-performing hospitals after acute myocardial infarction had longer life expectancies than patients treated in low-performing hospitals. This survival benefit occurred in the first 30 days and persisted over the long term.

AB - BACKGROUND: Although measles was eliminated in the United States in 2000, importations of the virus continue to cause outbreaks. We describe the epidemiologic features of an outbreak of measles that originated from two unvaccinated Amish men in whom measles was incubating at the time of their return to the United States from the Philippines and explore the effect of public health responses on limiting the spread of measles. METHODS: We performed descriptive analyses of data on demographic characteristics, clinical and laboratory evaluations, and vaccination coverage. RESULTS: From March 24, 2014, through July 23, 2014, a total of 383 outbreak-related cases of measles were reported in nine counties in Ohio. The median age of case patients was 15 years (range, <1 to 53); a total of 178 of the case patients (46%) were female, and 340 (89%) were unvaccinated. Transmission took place primarily within households (68% of cases). The virus strain was genotype D9, which was circulating in the Philippines at the time of the reporting period. Measles-mumps-rubella (MMR) vaccination coverage with at least a single dose was estimated to be 14% in affected Amish households and more than 88% in the general (non-Amish) Ohio community. Containment efforts included isolation of case patients, quarantine of susceptible persons, and administration of the MMR vaccine to more than 10,000 persons. The spread of measles was limited almost exclusively to the Amish community (accounting for 99% of case patients) and affected only approximately 1% of the estimated 32,630 Amish persons in the settlement. CONCLUSIONS: The key epidemiologic features of a measles outbreak in the Amish community in Ohio were transmission primarily within households, the small proportion of Amish people affected, and the large number of people in the Amish community who sought vaccination. As a result of targeted containment efforts, and high baseline coverage in the general community, there was limited spread beyond the Amish community.

AB - This work sought to document how Indonesian trans* FtM persons experienced discrimination across the interlinked domains of social networks, religious and educational institutions, employment and the workplace, and health care institutions. Objectives were (1) to map the discrimination experienced by trans* FtM individuals in Indonesia, and (2) to establish the specific priorities of the Indonesian trans* FtM community. In-depth interviews, focus groups, and participant observation was used involving 14 respondents. Findings revealed that respondents experienced othering through rejection, misidentification, harassment, "correction," and bureaucratic discrimination across the five preestablished domains. Health care and a lack of information emerged as areas of particular concern for respondents. This work calls for health care that is sensitive to the needs of trans* FtM people coupled with high-quality information to alleviate the cycles through which discrimination is sustained. PMID- 27705534 TI - Can Motor Proficiency in Preschool Age Affect Physical Activity in Adolescence? AB - BACKGROUND: This study investigated if motor proficiency (MP) in preschool age associate with physical activity (PA) in adolescence. METHODS: In 2004, the Bruininks-Oseretsky Test of Motor Proficiency-Short Form (BOTMP-SF) (7) was administered to 413 children, aged 4-6 years, who were classified to MP groups according to their BOTMP-SF total score (TS). In 2014, the PA of 106 former participants (47 boys, 59 girls) was measured with Omron pedometers. MP [three (high; above average; average)] * gender (two) ANOVA and Bonferroni tests were computed on average of steps/week. RESULTS: A significant interaction between the two factors was revealed (F = 15.27, p < .001, eta2=.153), indicating that MP influenced male and female PA differently. Only in average MP group, males presented higher PA than females, whereas there were no differences between the two genders in the higher MP groups. Moreover, the only significant difference in PA among male groups was that between high and above average MP groups, while in females there were significant differences among all groups. CONCLUSION: High MP at preschool age positively associated with the PA in adolescence, especially in females. Emphasis on the development of proficient young movers might be beneficial for lifelong PA. PMID- 27705533 TI - Personality and Defense Styles: Clinical Specificities and Predictive Factors of Alcohol Use Disorder in Women. AB - This study investigated personality traits and defense styles in order to determine clinical specificities and predictive factors of alcohol use disorders (AUDs) in women. A female sample, composed of AUD outpatients (n = 48) and a control group (n = 50), completed a sociodemographic self-report and questionnaires assessing personality traits (BFI), defense mechanisms and defense styles (DSQ-40). Comparative and correlational analyses, as well as univariate and multivariate logistic regressions, were performed. AUD women presented with higher neuroticism and lower extraversion and conscientiousness. They used less mature and more neurotic and immature defense styles than the control group. Concerning personality traits, high neuroticism and lower conscientiousness were predictive of AUD, as well as low mature, high neurotic, and immature defense styles. Including personality traits and defense styles in a logistic model, high neuroticism was the only AUD predictive factor. AUD women presented clinical specificities and predictive factors in personality traits and defense styles that must be taken into account in AUD studies. Implications for specific treatment for women are discussed. PMID- 27705535 TI - Validity of Skinfold Equations, Against Dual-Energy X-Ray Absorptiometry, in Predicting Body Composition in Adolescent Pentathletes. AB - PURPOSE: Body composition of adolescent athletes is often evaluated scientifically and in sports by using reference equations developed from nonathlete adolescent populations. The aim of this study was to analyze the validity of predictive equations based on skinfold measurements, as compared with dual-energy X-ray absorptiometry (DXA), to estimate body fat in adolescent modern pentathlon athletes. METHODS: 51 athletes, 27 male (mean age = 15.1 years; standard deviation, SD = 1.5 years) and 24 female (mean age = 14.2 years; SD = 2.5 years), were assessed using DXA, anthropometric parameters, sports practice anamnesis, and pubertal stages. Agreement between methods was tested with boxplots of mean comparisons using Student's t test (p < .05), and Bland-Altman plots. RESULTS: The body density equations of Durnin & Rahaman (1967) and Durnin & Womersley (1974) showed better agreement with DXA than the other predictive equations, for both females (difference between means=-2.03; 2SD = 8.44) and males (difference between means = 0.98; 2SD = 7.30). There were no mean differences between these equations and the reference method (DXA; p > .05), but they did display high variability (2SD). CONCLUSION: The high variability among results indicated imprecision. Predictive skinfold equations developed for nonathlete adolescents do not offer good validity for modern adolescent pentathlon athletes, and should be avoided. PMID- 27705267 TI - Daratumumab, Lenalidomide, and Dexamethasone for Multiple Myeloma. AB - BACKGROUND: Daratumumab showed promising efficacy alone and with lenalidomide and dexamethasone in a phase 1-2 study involving patients with relapsed or refractory multiple myeloma. METHODS: In this phase 3 trial, we randomly assigned 569 patients with multiple myeloma who had received one or more previous lines of therapy to receive lenalidomide and dexamethasone either alone (control group) or in combination with daratumumab (daratumumab group). The primary end point was progression-free survival. RESULTS: At a median follow-up of 13.5 months in a protocol-specified interim analysis, 169 events of disease progression or death were observed (in 53 of 286 patients [18.5%] in the daratumumab group vs. 116 of 283 [41.0%] in the control group; hazard ratio, 0.37; 95% confidence interval [CI], 0.27 to 0.52; P<0.001 by stratified log-rank test). The Kaplan-Meier rate of progression-free survival at 12 months was 83.2% (95% CI, 78.3 to 87.2) in the daratumumab group, as compared with 60.1% (95% CI, 54.0 to 65.7) in the control group. A significantly higher rate of overall response was observed in the daratumumab group than in the control group (92.9% vs. 76.4%, P<0.001), as was a higher rate of complete response or better (43.1% vs. 19.2%, P<0.001). In the daratumumab group, 22.4% of the patients had results below the threshold for minimal residual disease (1 tumor cell per 105 white cells), as compared with 4.6% of those in the control group (P<0.001); results below the threshold for minimal residual disease were associated with improved outcomes. The most common adverse events of grade 3 or 4 during treatment were neutropenia (in 51.9% of the patients in the daratumumab group vs. 37.0% of those in the control group), thrombocytopenia (in 12.7% vs. 13.5%), and anemia (in 12.4% vs. 19.6%). Daratumumab-associated infusion-related reactions occurred in 47.7% of the patients and were mostly of grade 1 or 2. CONCLUSIONS: The addition of daratumumab to lenalidomide and dexamethasone significantly lengthened progression-free survival among patients with relapsed or refractory multiple myeloma. Daratumumab was associated with infusion-related reactions and a higher rate of neutropenia than the control therapy.

AB - PURPOSE: To analyze how physical fitness (PF) improves in elite junior tennis players related to age, maturity, and performance level. METHODS: Elite junior tennis players (n = 113 boys, n = 83 girls) divided by performance level were monitored longitudinally from U14 to U16. Maturity, upper and lower-body power, speed, and agility were measured during subsequent competitive seasons. Improvement was analyzed per sex using multilevel analysis. RESULTS: PF components for boys and girls improved over age (U14-U16) (ES .53-.97). In boys, the more mature boys outscored the less mature boys in upper and lower-body power from U14-U16. In girls, high-ranked girls outscored lower-ranked girls on lower body power, speed, and agility (U14-U16) (p < .05). CONCLUSION: Boys and girls improved on all PF components during U14-U16. In boys, power was related to maturity. In girls, lower-body power, speed, and agility were related to tennis performance. This has important implications for talent development. PMID- 27705538 TI - The Adolescent Athlete: A Developmental Approach to Injury Risk. AB - With the advent of long-term athlete development programs and early sport specialization, the training of elite athletes now spans the period of adolescence. Adolescence represents a period of physical, psychosocial and cognitive development, but also a time of physical and psychological vulnerability. Changes in skeletal and physiological attributes coincide with an increased risk of sport related injury. A window of vulnerability is shaped by the properties of the musculoskeletal system, the influence of pubertal hormones and the lag time between physical and cognitive development. This article aims to challenge the assumption of adolescence as a time of increased vigor alone, by highlighting the presence of specific vulnerabilities, and proposing that the hormonal, musculoskeletal, and neurocognitive changes of adolescence may represent intrinsic risk factors for sport related injury. PMID- 27705539 TI - Distribution and Diversity of Bartonella washoensis Strains in Ground Squirrels from California and Their Potential Link to Human Cases. AB - We investigated the prevalence of Bartonella washoensis in California ground squirrels (Otospermophilus beecheyi) and their fleas from parks and campgrounds located in seven counties of California. Ninety-seven of 140 (69.3%) ground squirrels were culture positive and the infection prevalence by location ranged from 25% to 100%. In fleas, 60 of 194 (30.9%) Oropsylla montana were found to harbor Bartonella spp. when screened using citrate synthase (gltA) specific primers, whereas Bartonella DNA was not found in two other flea species, Hoplopsyllus anomalus (n = 86) and Echidnophaga gallinacea (n = 6). The prevalence of B. washoensis in O. montana by location ranged from 0% to 58.8%. A majority of the gltA sequences (92.0%) recovered from ground squirrels and fleas were closely related (similarity 99.4-100%) to one of two previously described strains isolated from human patients, B. washoensis NVH1 (myocarditis case in Nevada) and B. washoensis 08S-0475 (meningitis case in California). The results from this study support the supposition that O. beecheyi and the flea, O. montana, serve as a vertebrate reservoir and a vector, respectively, of zoonotic B. washoensis in California. PMID- 27705536 TI - Physiological Adaptations following Resistance Training in Youth Athletes-A Narrative Review. AB - PURPOSE: To understand the mechanisms for the effects of resistance training on functional parameters, and to assess the injury risk of the involved tissues, it is necessary to examine the underlying morphological and structural changes of the respective tissues. METHODS: The presented information on physiological adaptations have been deduced from cross-sectional studies comparing youth athletes with controls and children with adults as well as from longitudinal studies examining the effects of resistance training in untrained children and adolescents and in youth athletes. RESULTS: The evidence indicates, that training induced changes in motor performance rely partly on enhanced neuromuscular control, and partly on morphological adaptation of muscles and tendons, such as changes in muscle, muscle fiber and tendon cross-sectional area, muscle composition, and tendon material properties, with the bone also adapting by increasing bone mineral content and cortical area. CONCLUSION: Although the training induced adaptations of the investigated tissues follows similar principles in children as in adults, the magnitude of the adaptive response appears to be more subtle. As studies investigating physiological adaptation in youth athletes are sparse, more research in this area is warranted to elucidate the specific physiological stimulus-response relationship necessary for effective training programs and injury prevention. PMID- 27705540 TI - Periparturient characteristics of mares and their foals on a New Zealand Thoroughbred stud farm. AB - AIMS: To describe selected periparturient variables in a sample of Thoroughbred mares and their foals on a commercial stud farm in New Zealand. METHODS: Data were collected for 969 foaling records, from 592 mares, by foaling attendants from one Thoroughbred stud farm in the Waikato region of New Zealand for the breeding seasons 2008-2013, inclusive, and collated retrospectively. The associations between mare- and foal-level variables and gestation length, time of birth (expressed as the number of hours after midday), fetal membrane retention time, time for the foal to stand and suckle after birth, and foal mortality were quantified using linear and logistic regression models. RESULTS: Mean gestation length for mares in this study was 350 (min 296, max 429) days, and was shorter for filly foals (348 (min 296, max 429) days) compared with colt foals (350 (min 310, max 404) days) (p=0.001). Overall, 517/968 (53%) foalings occurred between 19:00 and 01:00 and 212/968 (22%) foalings occurred during daylight. Overall, 815/855 (95%) expelled their fetal membranes within 4 hours of parturition. The mean interval from birth to standing and to suckling was shorter (p<0.001) for filly foals than colts by 13 (95% CI=9-17) and 17 (95% CI=8-26) minutes, respectively. Dystocia was reported for 81/968 (8.4%) foalings with relative fetal oversize being the most common cause (36/81 (44%) cases). Perinatal foal death was recorded for 26/966 (2.7%) foalings. The odds of foal mortality decreased with increasing length of gestation (p=0.027), and were greater for colt than filly foals (p=0.042) and when dystocia was reported (p<0.001). CONCLUSIONS: Gestation length was influenced by the sex of the foal, as was the time taken for the foal to stand and suckle after birth. One fifth of mares foaled during daylight hours. The majority of mares in this study population expelled their fetal membranes within 4 hours of foaling. CLINICAL RELEVANCE: Accurate measures for periparturient behaviour can be important in the management of mares and newborn foals. Clinically relevant differences appear to exist between mares and foals in New Zealand and those in the Northern Hemisphere for some key parameters, likely as a result of differences in management and environment. The results of this study suggest that mares should be considered to have retained their membranes if not passed within 4 hours of parturition. PMID- 27705541 TI - Perceived Cross-Orientation Infidelity: Heterosexual Perceptions of Same-Sex Cheating in Exclusive Relationships. AB - For individuals in exclusive romantic relationships, the dynamics of sexual experimentation are nuanced. Extradyadic behavior outside of a relationship may be perceived as cheating or infidelity, with much of those perceptions driven by the biological sex of the perceiver. This study significantly reframes seminal research on perceptions of cheating with third-party friends by Kruger et al. (2013), to further nuance an evolutionary threat-based model. In doing so, this furthers our understanding of the associated perceptions of individuals in heterosexual relationships when confronted by partners' cheating with their same sex cross-orientation friends. Results indicate that perceptions of same-sex infidelity vary widely depending on the nature of the behaviors, with decreasing attribution given to sexual and erotic behaviors, close relational behaviors, and casual social interaction behaviors, respectively. Implications are discussed for a variety of sexual communities, as well as the impact of gender and relational status on perceptions of infidelity.

AB - Despite predictions of decline in mesothelioma following the ban of asbestos in most industrial countries, the incidence is still increasing globally, particularly in women. Because occupational exposure to asbestos is the main cause of mesothelioma, it occurs four- to eightfold more frequently in men than women, at a median age of 74 years. When mesothelioma is due to an environmental exposure, the M:F sex ratio is 1:1 and the median age at diagnosis is ~60 years. Studying environmental risk of mesothelioma is challenging because of the long latency period and small numbers, and because this type of exposure is involuntary and unknown. Individual-based methods cannot be used, and new approaches need to be found. To better understand the most recent trends of mesothelioma in the United States, all mesothelioma deaths reported to the Centers for Disease Control and Prevention (CDC) during 1999-2010 were analyzed. Among all mesothelioma deaths in the United States, the 1920s birth cohort significantly predominated, and the proportion of younger cohorts constantly decreased with time, suggesting a decline in occupational exposure in these cohorts. The M:F mesothelioma sex ratio fell with time, suggesting an increased proportion of environmental cases. Environmental exposures occur in specific geographic areas. At the large scale of a state, mesotheliomas related to environmental exposure are diluted among occupational cases. The spatial analysis at a smaller scale, such as county, enables detection of areas with higher proportions of female and young mesothelioma cases, thus indicating possible environmental exposure, where geological and environmental investigations need to be carried out. PMID- 27705544 TI - Malignant mesothelioma in Australia 2015: Current incidence and asbestos exposure trends. AB - Australia is known to have had the highest per-capita asbestos consumption level of any nation, reaching a peak in the 1970s. Although crocidolite was effectively banned in the late 1960s, and amosite use ceased in the mid 1980s, a complete asbestos ban was not implemented until 2003. This resulted in an epidemic of asbestos-related disease, which has only now reached its peak. Between 1982 and 2011, 13,036 individuals were newly diagnosed with malignant mesothelioma, with 690 diagnosed in 2011. A further 778 cases were identified between 1945 and 1981 from retrospective searches and the first 2 years of the Australian Mesothelioma Program. The age-standardized malignant mesothelioma incidence rate has leveled off in the last 10 years (2.8 per 100,000 in 2011). There has been a marked increase over time in the age-specific incidence rates for individuals aged 75 years or older. Data from the current Australian Mesothelioma Registry on asbestos exposure history in Australia is available for 449 subjects diagnosed between July 1, 2010, and April 1, 2015. This asbestos exposure history data show that 60% (n = 268) of cases had probable or possible occupational asbestos exposure, with trade-based jobs being the most frequent sources of occupational asbestos exposure. In addition, out of the 449 cases, 377 were recorded as having probable or possible nonoccupational asbestos exposure. Continuous vigilance toward changes over time in the settings in which people are exposed to asbestos and in the descriptive epidemiology of malignant mesothelioma is recommended to enable a comprehensive understanding of the current and future impact of asbestos related diseases in Australia. PMID- 27705546 TI - Five years update on relationships between malignant pleural mesothelioma and exposure to asbestos and other elongated mineral particles. AB - Despite the reduction of global asbestos consumption and production due to the ban or restriction of asbestos uses in more than 50 countries since the 1970s, malignant mesothelioma remains a disease of concern. Asbestos is still used, imported, and exported in several countries, and the number of mesothelioma deaths may be expected to increase in the next decades in these countries. Asbestos exposure is the main risk factor for malignant pleural mesothelioma, but other types of exposures are linked to the occurrence of this type of cancer. Although recent treatments improve the quality of life of patients with mesothelioma, malignant pleural mesothelioma remains an aggressive disease. Recent treatments have not resulted in appreciable improvement in survival, and thus development of more efficient therapies is urgently needed. The development of novel therapeutic strategies is dependent on our level of knowledge of the physiopathological and molecular changes that mesothelial cells acquired during the neoplastic process. During the past 5 years, new findings have been published on the etiology, epidemiology, molecular changes, and innovative treatments of malignant pleural mesothelioma. This review aims to update the findings of recent investigations on etiology, epidemiology, and molecular changes with a focus on (1) attributable risk of asbestos exposure in men and women and (2) coexposure to other minerals and other elongated mineral particles or high aspect ratio nanoparticles. Recent data obtained on genomic and gene alterations, pathways deregulations, and predisposing factors are summarized. PMID- 27705547 TI - Pathology analysis for mesothelioma study in the United Kingdom: Current practice and historical development. AB - Following up on the largest case-control study of malignant mesothelioma yet performed, investigators at the London School of Hygiene and Tropical Medicine assessed 1732 male and 670 female cases as of May 2013. Epidemiological findings of a subset of these were published previously, excluding patients who died or who refused to be interviewed. Pathology reports were collected for subjects, including those both eligible and ineligible for epidemiology study based on vital status. The current investigation examined 860 cases having pathology reports available. Sixty-one cases were diagnosed using cytology only, often with equivocal diagnoses, while 799 reported at least a biopsy of the tumor. Of these, 748 had pathology sufficiently detailed for evaluation. These reports were examined for basis of diagnosis, differences between study cases and ineligible cases, pathology characteristics, and immunohistochemical and other tests used. The most prominent subtype was epithelioid (64% of study cases but only 49% of ineligible cases). Biphasic subtype was present in 10% of study cases and 16% of those ineligible. Sarcomatoid subtype was present in 7% of study cases and 19% of ineligible cases, most of whom died. Twelve percent of study cases displayed no specified subtype, versus 7% of ineligible cases. Of recorded immunohistochemical stains specific for mesothelial cell origin, calretinin (95%) and CK 5/6 or CK5 alone (84%) were by far the most common. Calretinin and CK 5/6 or CK 5 alone were also most sensitive and positive in 92% of cases presenting with surgical pathology report. Ninety percent of cases had at least one immunohistochemical marker for possible lung carcinoma applied, with BER-Ep4 and TTF-1 the most frequent at 68% and CEA at 58%. TTF-1 and CEA were positive in 1% or less of cases. Patterns of use and positive and negative results for each of these as well as other immunohistochemical stains are presented and discussed, along with a brief historical description of their development and use. Possible effects of the pathologic analysis on the results of previously published and future epidemiological studies are discussed. PMID- 27705549 TI - Mesothelioma from asbestos exposures: Epidemiologic patterns and impact in the United States. AB - Mesothelioma, a rare tumor, is highly correlated with asbestos exposure. Mesothelioma, similar to all asbestos-related diseases, is dose/intensity dependent to some degree, and studies showed the risk of mesothelioma rises with cumulative exposures. Multiple processes occur in an individual before mesothelioma occurs. The impact of mesothelioma in the United States has been continuous over the last half century, claiming between 2,000 and 3,000 lives each year. Mesothelioma is a preventable tumor that is more frequently reported as associated with asbestos exposure among men than women. However, the rate of asbestos-associated mesothelioma is on the rise among women due to better investigation into their histories of asbestos exposure. It is of interest that investigators detected asbestos-associated cases of mesothelioma in women from nonoccupational sources-that is, bystander, incidental, or take-home exposures. It is postulated that asbestos-associated mesotheliomas, in both men and women, are likely underreported. However, with the implementation of the most recent ICD 10 coding system, the correlation of mesothelioma with asbestos exposure is expected to rise to approximately 80% in the United States. This study examined the demographic and etiological nature of asbestos-related mesothelioma. PMID- 27705548 TI - Quantitative structure-mesothelioma potency model optimization for complex mixtures of elongated particles in rat pleura: A retrospective study. AB - Cancer potencies of mineral and synthetic elongated particle mixtures, including asbestos fibers, are influenced by changes in fiber dose composition, bioavailability, and biodurability in combination with relevant cytotoxic dose response relationships. An extensive rat intrapleural dose characterization data set with a wide variety of elongated particles physicochemical properties facilitated statistical analyses of pleural mesothelioma response data combined from several studies for evaluation of alternative dose-response models. Utilizing logistic regression of individual elongated particle dimensional variations within each test sample, four major findings emerged: (1) Mild acid leaching provides superior prediction of tumor incidence compared to samples that were not leached; (2) sum of the elongated particle surface areas from mildly acid-leached samples provides the optimum holistic dose-response model; (3) progressive removal of dose associated with very short and/or thin elongated particles significantly degrades the resultant particle count and surface area dose-based predictive model fits; and (4) alternative biologically plausible model adjustments provide evidence for reduced potency of elongated particles with aspect ratios less than 8 and lengths greater than 80 um. Regardless of these adjustments, the optimum predictive models strongly incorporate potency attributable to abundant short elongated particles in proportion to their surface area. Transmission electron microscopy analyses of low-temperature-ashed pleural membrane and lung tissues 5.5 mo post intrapleural exposures do not support hypotheses that short elongated particles that reach the pleural space are rapidly eliminated. Low-aspect-ratio elongated particles were still abundant in pleural membrane tissues but may have reduced potencies due to aggregation tendencies and therefore lower potential for intracellular presence. PMID- 27705550 TI - Tyler asbestos workers: A mortality update in a cohort exposed to amosite. AB - The Tyler asbestos plant produced pipe insulation from 1954 to 1972 and exclusively used amosite asbestos. There were 1130 former workers of this plant during the period of operation. A death certificate mortality analysis was published regarding this plant in 1998 for the period through 1993. This study represents an update of the mortality analysis with additional certificates collected for deaths occurring through 2011.Searches of the National Death Index database were conducted in 2004 and again in 2013. At the time of the latter search, only deaths occurring through 2011 were available. In total, 265 distinct additional death certificates were secured and added to 304 available from the original study. After the new certificates were coded (ICD-9), data were analyzed using the Centers for Disease Control and Prevention Life Table Analysis System (LTAS) and standard mortality ratios (SMR) generated with 95% confidence limits (CL). LTAS constructs cause-specific mortality rates by age, gender, race, and person-time at risk, and compares observed rates with a referent population in order to derive SMR. A significant excess number of deaths due to nonmalignant respiratory disease (asbestosis) and from select malignant neoplasms were identified. There were in total 23 mesothelioma deaths (4% of deaths), with 16 pleural and 7 peritoneal. The SMR for malignant neoplasms of the trachea, bronchus, and lung was 244 (with 95% CL 196, 300), suggesting that exposed workers from this cohort were nearly 2.5-fold (244 %) more likely to die from this cause as the general referent population. The analysis also showed that exposures of short duration (<6 mo) produced significantly elevated SMR for all respiratory cancers, lung cancer, and pleural mesothelioma. There was a significant difference in median duration of exposure for mesothelioma types, confirming association of peritoneal mesothelioma with longer duration of exposure. Deaths due to intestinal cancer (predominantly colon; not including rectum) were also found in excess. The mortality experience of the Tyler cohort continues to be followed with great interest, given the exclusivity of exposure to amosite. Data confirm the inherent pathogenicity of this fiber type for nonmalignant disease as well as select cancers, particularly relevant given the importance of this amphibole's use in the United States.

AB - BACKGROUND: Advent of minimally-invasive esophagectomy necessitated the incorporation of stapled anastomotic techniques especially for intrathoracic anastomosis. We present our approach to the Ivor Lewis esophagectomy highlighting a simple modification in the anastomotic technique and review our experience with anastomotic outcomes. METHODS: With IRB approval, patients who underwent Ivor Lewis esophagectomy with circular-stapled end-to-end anastomosis (EEA) were identified, divided into three equal sequential cohorts (A, B, and C), and compared for perioperative outcome. Cohorts were divided in a chronological order to have equal number of patients in each group. RESULTS: Seventy-five patients underwent Ivor Lewis esophagectomy with circular stapled (EEA-25/28) anastomosis. Group A had longer median postoperative hospital stay and median postoperative ICU stay compared to Groups B and C. Ten patients (13%) had anastomotic leak-one patient required redo-anastomosis and other patients were managed with endoscopic interventions. There was significant decrease in rate of anastomotic leak with experience (8 versus 1 versus 1, P = .004). There were two perioperative deaths, one each in Groups A and C, including one death due to anastomotic leak (Group A). CONCLUSION: Use of simple modifications to stapled EEA, as described here, has led to decrease in anastomotic leaks following Ivor Lewis esophagectomy. PMID- 27705545 TI - Investigating palygorskite's role in the development of mesothelioma in southern Nevada: Insights into fiber-induced carcinogenicity. AB - Similar to asbestos fibers, nonregulated mineral fibers can cause malignant mesothelioma (MM). Recently, increased proportions of women and young individuals with MM were identified in southern Nevada, suggesting that environmental exposure to carcinogenic fibers was causing the development of MM. Palygorskite, a fibrous silicate mineral with a history of possible carcinogenicity, is abundant in southern Nevada. In this study, our aim was to determine whether palygorskite was contributing to the development of MM in southern Nevada. While palygorskite, in vitro, displayed some cytotoxicity toward primary human mesothelial (HM) cells and reduced their viability, the effects were roughly half of those observed when using similar amounts of crocidolite asbestos. No Balb/c (0/19) or MexTAg (0/18) mice injected with palygorskite developed MM, while 3/16 Balb/c and 13/14 MexTAg mice injected with crocidolite did. Lack of MM development was associated with a decreased acute inflammatory response, as injection of palygorskite resulted in lower percentages of macrophages (p = .006) and neutrophils (p = .02) in the peritoneal cavity 3 d after exposure compared to injection of crocidolite. Additionally, compared to mice injected with crocidolite, palygorskite-injected mice had lower percentages of M2 (tumor promoting) macrophages (p = .008) in their peritoneal cavities when exposed to fiber for several weeks. Our study indicates that palygorskite found in the environment in southern Nevada does not cause MM in mice, seemingly because palygorskite, in vivo, fails to elicit inflammation that is associated with MM development. Therefore, palygorskite is not a likely contributor to the MM cases observed in southern Nevada. PMID- 27705725 TI - Prostate, Breast and Ovarian Cancer Genetic Risk Assessment: Connecting the Dots.

AB - Six carbapenem-resistant isolates of Acinetobacter baumannii were recovered from untreated and treated municipal wastewater of the capital city of Zagreb, Croatia. Molecular identification of environmental isolates of A. baumannii was performed by amplification, sequencing, and phylogenetic analyses of rpoB gene. The presence of blaOXA genes encoding OXA-type carbapenemases (OXA-51-like, OXA 23, and OXA-40-like) was confirmed by multiplex PCR and sequencing. Phylogenetic analyses corroborated the affiliation of detected blaOXA genes to three different clusters and showed association of environmental OXAs with those described from clinical isolates. This result suggests that isolates recovered from municipal wastewater are most probably of clinical origin. Furthermore, the presence of OXA 40-like (OXA-72) in an environmental A. baumannii isolate is reported for the first time. Persistence of A. baumannii harboring the clinically important OXAs in the wastewater treatment process poses a potentially significant source for horizontal gene transfer and implications for wider spread of antibiotic resistance genes. PMID- 27705664 TI - Genetic Mapping of Stem Rust Resistance to Puccinia graminis f. sp. tritici Race TRTTF in the Canadian Wheat Cultivar Harvest. AB - Stem rust, caused by Puccinia graminis f. sp. tritici, is a destructive disease of wheat that can be controlled by deploying effective stem rust resistance (Sr) genes. Highly virulent races of P. graminis f. sp. tritici in Africa have been detected and characterized. These include race TRTTF and the Ug99 group of races such as TTKSK. Several Canadian and U.S. spring wheat cultivars, including the widely grown Canadian cultivar 'Harvest', are resistant to TRTTF. However, the genetic basis of resistance to TRTTF in Canadian and U.S. spring wheat cultivars is unknown. The objectives of this study were to determine the number of Sr genes involved in TRTTF resistance in Harvest, genetically map the resistance with DNA markers, and use markers to assess the distribution of that resistance in a panel of Canadian cultivars. A doubled haploid (DH) population was produced from the cross LMPG-6S/Harvest. The DH population was tested with race TRTTF at the seedling stage. Of 92 DH progeny evaluated, 46 were resistant and 46 were susceptible which perfectly fit a 1:1 ratio indicating a single Sr gene was responsible for conferring resistance to TRTTF in Harvest. Mapping with single nucleotide polymorphism (SNP) and simple sequence repeat (SSR) markers placed the resistance gene distally on the chromosome 6AS genetic map, which corresponded to the location reported for Sr8. SSR marker gwm459 and 30 cosegregating SNP markers showed the closest linkage, mapping 2.2 cM proximal to the Sr gene. Gene Sr8a confers resistance to TRTTF and may account for the resistance in Harvest. Testing a panel of Canadian wheat cultivars with four SNP markers closely linked to resistance to TRTTF suggested that the resistance present in Harvest is present in many Canadian cultivars. Two of these SNP markers were also predictive of TRTTF resistance in a panel of 241 spring wheat lines from the United States, Canada, and Mexico. PMID- 27705727 TI - Robotic versus laparoscopic radical nephrectomy: comparative analysis and cost considerations. AB - INTRODUCTION: Robotic-assisted laparoscopic radical nephrectomy (RRN) is an increasing utilized alternative to laparoscopic radical nephrectomy (LRN); however, there is a little data on comparative effectiveness and cost of these procedures. We analyzed perioperative outcomes and hospital charge difference among patients undergoing laparoscopic radical nephrectomy (LRN) and robotic radical nephrectomy (RRN). MATERIALS AND METHODS: Our institutional renal mass registry was queried for patients who underwent either LRN or RRN from 2010 to 2014. Demographic, perioperative outcomes and hospital charge data were compared between surgical approaches. RESULTS: Overall, 319 minimally invasive radical nephrectomies were performed during the study period. Of these, 243 were LRN and 76 were RRN. Patient demographic and tumor characteristics were similar between groups. Among operative characteristics, operative time (136 min versus 139 min, p = 0.531), intraoperative complications (2.8% versus 2.0%, p = 0.650), and length of stay (2 days versus 2 days, p = 0.745) were similar for LRN and RRN, respectively. Estimated blood loss (50 mL versus 100 mL, p = 0.041) and rate of conversion to an alternative surgical approach (1.0% versus 11.1%, p < 0.001) were higher in RRN. RRN cases were also more likely to include lymph node dissection (12.6% versus 24.2%, p = 0.031). Total charges trended higher for RRN but did not meet traditional levels of significance ($14,913 versus $16,265, p = 0.171). CONCLUSIONS: RRN appears to be a clinically equivalent alternative to LRN with similar perioperative outcomes, albeit at greater hospital charges.

We sought to evaluate incidence of ureteral calculi on NCT in patients with FP, and to determine if clinical variables are associated with higher detection rates. MATERIALS AND METHODS: Retrospective review identified 613 patients undergoing NCT for FP. Patient clinical data, NCT findings, and intervention were analyzed. Focus was placed on variables commonly associated with urolithiasis (Vstone), comprising hematuria, nausea/vomiting, and prior stone history. Statistical analysis was performed to identify risk of ureteral stones based on number and type of Vstone. RESULTS: No stone disease was identified on NCT in 175 patients (28.5%). NCT demonstrated 214 (35%), 72 (12%), and 152 (25%) patients with stones located in the kidney, ureter, or both, respectively. Only 33 (5%) patients had FP as their sole Vstone, with ureteral calculi identified in 6% of this cohort. The rate of ureteral calculi increased with more Vstone. Patients having all four Vstone were found to have the highest rate of ureteral stones (59%). Statistical analysis demonstrated a statistically significantly increased relative risk of stone formation given three or four Vstone when compared with FP alone. CONCLUSIONS: Whereas isolated FP is associated with a lower rate of ureteral calculus detection, a significant increased relative risk of ureteral calculus is seen in patients with additional clinical variables associated with stone disease. Accordingly, it may be possible to improve detection rates of ureteral stones through the use of additional clinical variables to guide NCT selection.

AB - INTRODUCTION: To evaluate erectile function recovery following robotic-assisted radical prostatectomy (RARP) according to preoperative sexual health inventory for men (SHIM) score stratification. MATERIALS AND METHODS: We prospectively collected data on 250 consecutive patients who underwent RARP by a single surgeon between October 2006 and October 2012. Thirty-six patients were excluded because of lack of preoperative SHIM score. All patients had a minimum follow up of 2 years. Patients were divided into four groups according to their preoperative SHIM score: group 1 with normal potency (SHIM 22-25), group 2 with mild ED (SHIM 17-21), group 3 with mild-moderate ED (SHIM 12-16) and group 4 with moderate severe ED (SHIM 1-11). Patients were followed at 3, 6, 9, 12, 18, 24 months intervals and twice yearly thereafter. SHIM questionnaire and erection hardness scale (EHS) score were collected at each visit. Potency was defined as successful penetration during intercourse (EHS score 3-4) with or without phosphodiesterase type 5-inhibitor (PDE5-I). RESULTS: After exclusion, 214 patients were evaluated. The number of patients in group 1, 2, 3 and 4 were 95, 59, 26 and 34, respectively. At 3, 6, 9, 12, 18, 24 months, SHIM scores and potency rates were statistically different between groups 1 versus 2 versus 3 versus 4 (p < 0.01, at each time point). Patients in each group 1, 2 and 3 showed a statistically significant improvement in potency rates and SHIM scores at consecutive follow up visits up to 24 months (p < 0.01, for each potency group). Potency rates at 24 months for groups 1 to 4 were 83.3%, 54.5%, 50.0%, and 20.7%, respectively (p < 0.001). CONCLUSION: For proper patient counseling and better prediction of erectile function recovery after RARP, it is important to stratify patients according to preoperative SHIM scores. Setting realistic expectations may increase patient satisfaction. PMID- 27705729 TI - Urinalysis findings are not predictive of positive urine culture in patients with indwelling stents. AB - INTRODUCTION: Indwelling stents produce symptoms and urinalysis findings mimicking urinary tract infection (UTI). In this study, we investigated the correlation of urinalysis findings with urine culture in patients with indwelling ureteral stents. MATERIALS AND METHODS: All patients with ureteral stents who underwent stent removal in urology clinic from July 2013 to January 2015 and had urine culture available immediately prior to stent removal were included in this study. Urine culture results as well as age, gender, duration of indwelling stent, and reason for stent placement were collected. RESULTS: A total of 122 patients were included in this study. The two most common reasons for ureteral stent placement included urolithiasis (65.6%) and renal transplant (22.1%). Red blood cell (RBC), leukocytes and nitrite were positive in 92.9%, 70.2% and 17.9% of urine samples respectively. Only 17 patients (13.9%) had positive urine culture. Although renal transplant patients had significantly longer duration of stent retention, no statistically significant difference was noted in rate of positive urine culture compared to urolithiasis patients (p = 1.0). Among patients with positive urine culture, 62.5% had resistant bacteria to common antibiotic treatments and two patients had yeast in urine culture (12.5%). The duration of stent retention did not correlate with bacterial resistance. Multivariate analysis failed to show significant correlation of gender, reason for stent, stent duration, RBC and nitrite with positive urine culture. CONCLUSIONS: Positive findings on urinalysis in patients with indwelling ureteral stent have poor correlation to positive urine culture and therefore the use of urine culture to diagnose UTI is warranted. PMID- 27705731 TI - Poor split renal function and age in adult patients with ureteropelvic junction obstruction do not impact functional outcomes of pyeloplasty. AB - INTRODUCTION: To examine if poor preoperative split renal function (SRF) and age influence pyeloplasty outcomes in adults with ureteropelvic junction obstruction (UPJO). MATERIALS AND METHODS: We retrospectively reviewed our pyeloplasty experience in adults with UPJO from 2004 to 2014. Patients with solitary kidneys or missing renal scans were excluded. Renal scans were performed at 6 weeks, 8 months, and 20-24 months postoperatively. Demographics, operative approaches, and pre and postoperative SRF and diuretic half-times (T1/2) were obtained. Patients were stratified by preoperative SRF (<= or > 25%) and age. Cox regression analyses were performed to explore predictors for stability or improvement of SRF. RESULTS: A total of 139 patients met the study criteria: 15 and 124 with preoperative SRF <= 25% and > 25%, respectively. Median follow up was 11 months, 12.9% of patients experienced worsening, 67.6% stability, and 19.4% improvement in SRF at last follow up. Median change in SRF was similar between groups; however, patients with lower preoperative SRF more frequently experienced improvement or worsening of SRF (p = 0.045). Failure rates (need for additional surgery) were comparable (p = 1.000). No significant differences were observed in SRF dynamicity when stratified by age (p = 0.120). On univariate Cox analysis, older age was predictive of stability or improvement in SRF across the entire cohort (HR 1.013, p = 0.016), while preoperative SRF was not (HR 1.007, p = 0.429). CONCLUSIONS: Poor SRF (<= 25%) and age were not associated with worse outcomes after pyeloplasty for UPJO. Our results suggest that older adults with UPJO and patients with poor ipsilateral SRF should not be excluded from pyeloplasty. PMID- 27705732 TI - Infectious complications associated with the use of temporary prostatic urethral stents in patients with benign prostatic hyperplasia. AB - INTRODUCTION: To examine the infectious outcomes after the insertion of the temporary prostatic urethral stent (TPUS) in benign prostatic hyperplasia (BPH) patients. MATERIAL AND METHODS: Between November 2007 and September 2012, ninety TPUS were used in 33 patients with BPH at our institution. All patients had negative urine cultures prior to the first stent insertion. TPUS were sent for cultures at time of removal or exchange. Stents were removed at the time of definite surgical intervention, at 4-6 weeks, or when patients elected another course of treatment. Colonization was defined as asymptomatic positive stent culture. Infection was defined as symptomatic positive stent culture requiring treatment. Infection and colonization rates are reported. Logistic regression was used to examine the predictors of infection at any point. Predictors examined were age, body mass index, history of prostate cancer, diabetes mellitus, hyperlipidemia, coronary artery disease, neurologic disorder, erectile dysfunction and the sequence of stent placement. RESULTS: The majority of the subjects, 72% (24/33) had 1-2 stents, 9.0% (3/33) had 3-4 stents, 6.0% (2/33) had 5-6 stents, and 12% (4/33) of patients had more than 6 stents. From the 69 available culture results, the symptomatic infection rate was 16% (11/69) (95% CI: 8.2%-26.7%). The colonization rate was 58% (40/69) (95% CI: 45.5%-69.7%). None of the predictors examined were identified as a predictor of infection. There was no colonization detected when stents were removed in the first 20 days. CONCLUSION: Infection rates with TPUS in BPH patients are acceptable and early removal may prevent colonization. PMID- 27705610 TI - Supplements, nutrition, and alternative therapies for the treatment of traumatic brain injury. AB - Studies using traditional treatment strategies for mild traumatic brain injury (TBI) have produced limited clinical success. Interest in treatment for mild TBI is at an all time high due to its association with the development of chronic traumatic encephalopathy and other neurodegenerative diseases, yet therapeutic options remain limited. Traditional pharmaceutical interventions have failed to transition to the clinic for the treatment of mild TBI. As such, many pre clinical studies are now implementing non-pharmaceutical therapies for TBI. These studies have demonstrated promise, particularly those that modulate secondary injury cascades activated after injury. Because no TBI therapy has been discovered for mild injury, researchers now look to pharmaceutical supplementation in an attempt to foster success in human clinical trials. Non traditional therapies, such as acupuncture and even music therapy are being considered to combat the neuropsychiatric symptoms of TBI. In this review, we highlight alternative approaches that have been studied in clinical and pre clinical studies of TBI, and other related forms of neural injury. The purpose of this review is to stimulate further investigation into novel and innovative approaches that can be used to treat the mechanisms and symptoms of mild TBI. PMID- 27705733 TI - A standardized surgical technique for removal of the Interstim tined lead. AB - INTRODUCTION: Explantation of the Interstim sacral neuromodulation (SNM) device is occasionally necessary. Removing the tined lead can put strain on the lead, resulting in a possible break and retained fragments. The Food and Drug Administration (FDA) released a notification regarding health consequences related to retained lead fragments. We describe a novel and safe surgical technique for removing the Interstim device and permanent lead. MATERIALS AND METHODS: We searched the Manufacturer and User Facility Device Experience (MAUDE) database for complications related to tined lead removal and searched the database of a single surgeon at our institution. Our standardized technique for tined lead removal is as follows. An incision is made over the previous lead insertion site and the lead is isolated and externalized. The fibrous encapsulation is dissected off the lead to expose the tines and ensure the lead is free from adhesions. The lead is removed by wrapping it around a curved hemostat and turning it under tension. If the lead breaks, the incision is extended and dissection is carried down to the sacral body to remove all fragments. RESULTS: Twenty-eight patients had their tined lead removed between 2009 and 2015 after being in place a median of 2.00 years (IQR 1.32-3.32 years). One lead broke (3.6%) during removal over the 6 years using our standardized approach. CONCLUSION: Permanent tined leads can break on removal and retained fragments can pose significant health consequences. Our technique standardizes the approach for removal and is safe and effective in our series. PMID- 27705734 TI - Wire in the hole: a case series of eroded intrapubic wire sutures causing genitourinary complications in the bladder exstrophy complex. AB - Bladder exstrophy and cloacal exstrophy are rare congenital defects of the genitourinary tract that require complex surgical reconstruction. Malrotation of the bony pelvis causes a characteristic diastasis of the pubic symphysis, which is surgically reduced at the time of initial bladder closure. For a successful primary closure without tension such that the bladder can be placed deep within the pelvis, pelvic osteotomy is often used. However, alternative techniques have been utilized to bring the pubic rami into apposition. The authors present four bladder/cloacal exstrophy patients in which an intrapubic wire was used for pubic apposition, resulting in significant genitourinary complications. PMID- 27705740 TI - To cut or not to cut... that remains the question. PMID- 27705737 TI - Early pregnancy likely caused by an intravesical intrauterine device. AB - A 42-year-old female with remote history of intrauterine device (IUD) placement presented with gross hematuria, urinary urgency, and dyspareunia. Cystoscopy showed an encrusted, free-floating intravesical foreign body consistent with a heavily calcified IUD. It was removed endoscopically using holmium laser cystolitholapaxy. The patient remained symptom free postoperatively. While most intravesical IUDs are thought to be the result of migration after several months, this patient became pregnant within 4 weeks after initial insertion. Therefore this may represent a case either of early intravesical migration or of accidental IUD placement into the bladder at the time of initial insertion. PMID- 27705736 TI - MLL translocation in two castration-resistant prostate cancer patients. AB - The mixed-lineage leukemia (MLL) protein acts as a histone methyltransferase regulating multiple genetic elements. Rearrangements of the MLL gene result in expression of MLL-fusion proteins that occur in some acute leukemias and are associated with poor prognosis. The MLL protein complex has been shown to interact with the androgen receptor via the MLL-menin subunit, thus promoting gene activation. The presence of MLL translocation has not been previously reported in patients with castrate resistant prostate cancer (CRPC). We describe two cases of metastatic CRPC with a translocation in the MLL gene detected by a specific fluorescent in situ hybridization (FISH) assay. Both patients had an aggressive course and succumbed to the illness. PMID- 27705735 TI - Pyelocystostomy for treatment of recurrent nephrolithiasis and ureteropelvic junction obstruction in a pelvic kidney. AB - Patients with pelvic kidneys are at an increased risk of developing ureteropelvic junction obstruction (UPJO) and nephrolithiasis with limited endourologic options. A 54-year-old man with a left pelvic kidney, recurrent nephrolithiasis, and 12 previous ureteroscopies presented with left UPJO and lower pole calyceal stones. After two failed ureteroscopic attempts, an open pyelolithotomy and pyelocystostomy were performed. After 30 months, he continues to be asymptomatic without recurrence of nephrolithiasis. This constitutes the fifth such reported case. Therefore, pyelocystotomy is a good option for patients with pelvic kidneys, UPJO and recurrent nephrolithiasis refractory to endourologic procedures. PMID- 27705738 TI - How I do it: Same day discharge for transurethral resection of prostate using Olympus PlasmaButton and PlasmaLoop. AB - Benign prostatic hyperplasia (BPH) is one of the most common conditions affecting older men. Transurethral resection of the prostate (TURP) has widely been considered the gold standard in surgical treatment for BPH. However, this procedure remains largely an inpatient procedure. Inpatient admission ultimately adds to healthcare cost and patient morbidity. In this article, we present an alternative methodology to treat BPH using combination Olympus PlasmaButton and Olympus PlasmaLoop therapy. Preliminary results from our experience suggest improved hemostasis with adequate resection, allowing a majority of our patients to be discharged the same day of the procedure. We describe our novel technique as a safe and effective way to possibly treat BPH in an outpatient setting. PMID- 27705739 TI - Canadian Pediatrics Society position statement on newborn circumcision: a risk benefit analysis revisited. AB - INTRODUCTION: The Canadian Pediatrics Society (CPS) recently released a position statement on early infant (newborn) male circumcision (EIMC). It concluded that since benefits do not exceed risks, circumcision should only be performed on boys in high-risk populations or circumstances. This contradicts recommendations by the American Academy of Pediatrics and the Centers for Disease Control and Prevention (CDC) whose policies each support more widespread implementation of EIMC. Here we review the CPS statement, particularly its risk-benefit analysis, to determine the basis for this disparity. MATERIALS AND METHODS: We performed a risk-benefit analysis based on relevant literature retrieved from PubMed reporting frequency of each condition, giving emphasis to data from meta-analyses and randomized controlled trials. RESULTS: Although the CPS recognized some of the benefits of EIMC, its inclusion of weak studies of adverse events led to these being over-estimated, greatly exceeding the figure of < 0.5% found in a recent large, technically robust, CDC study. The CPS under-estimated benefits by omitting balanitis, balanoposthitis, prostate cancer, some sexually transmitted infections and candidiasis, and failing to consider lifetime prevalence of urinary tract infections in uncircumcised males. In contrast, our more inclusive risk-benefit analysis found benefits exceed risks by approximately 100 to 1 and that lack of EIMC contributes to adverse medical conditions, some potentially fatal, in approximately half of uncircumcised males. CONCLUSIONS: The 2015 CPS position statement on EIMC is at odds with the evidence. The CPS conclusions stem from errors in its risk-benefit analysis. In light of our findings we recommend the CPS issue a revised statement. PMID- 27705741 TI - Abstracts of the Mid-Atlantic Section of the American Urological Association Annual Meeting. October 6 - 9, 2016 Hot Springs, VA. PMID- 27705742 TI - Autocorrelation structure at rest predicts value correlates of single neurons during reward-guided choice. AB - Correlates of value are routinely observed in the prefrontal cortex (PFC) during reward-guided decision making. In previous work (Hunt et al., 2015), we argued that PFC correlates of chosen value are a consequence of varying rates of a dynamical evidence accumulation process. Yet within PFC, there is substantial variability in chosen value correlates across individual neurons. Here we show that this variability is explained by neurons having different temporal receptive fields of integration, indexed by examining neuronal spike rate autocorrelation structure whilst at rest. We find that neurons with protracted resting temporal receptive fields exhibit stronger chosen value correlates during choice. Within orbitofrontal cortex, these neurons also sustain coding of chosen value from choice through the delivery of reward, providing a potential neural mechanism for maintaining predictions and updating stored values during learning. These findings reveal that within PFC, variability in temporal specialisation across neurons predicts involvement in specific decision-making computations. PMID- 27705743 TI - C. elegans GLP-1/Notch activates transcription in a probability gradient across the germline stem cell pool. AB - C. elegans Notch signaling maintains a pool of germline stem cells within their single-celled mesenchymal niche. Here we investigate the Notch transcriptional response in germline stem cells using single-molecule fluorescence in situ hybridization coupled with automated, high-throughput quantitation. This approach allows us to distinguish Notch-dependent nascent transcripts in the nucleus from mature mRNAs in the cytoplasm. We find that Notch-dependent active transcription sites occur in a probabilistic fashion and, unexpectedly, do so in a steep gradient across the stem cell pool. Yet these graded nuclear sites create a nearly uniform field of mRNAs that extends beyond the region of transcriptional activation. Therefore, active transcription sites provide a precise view of where the Notch-dependent transcriptional complex is productively engaged. Our findings offer a new window into the Notch transcriptional response and demonstrate the importance of assaying nascent transcripts at active transcription sites as a readout for canonical signaling. PMID- 27705748 TI - Cornus mas L. (cornelian cherry), an important European and Asian traditional food and medicine: Ethnomedicine, phytochemistry and pharmacology for its commercial utilization in drug industry. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Cornus mas L. (cornelian cherry) fruits have been used for centuries as traditional cuisine and folk medicine in various countries of Europe and Asia. In folk medicines, the fruits and other parts of the plant have been used for prevention and treatment of a wide range of diseases such as diabetes, diarrhea, gastrointestinal disorders, fevers, rheumatic pain, skin and urinary tract infections, kidney and liver diseases, sunstroke, among others. This review provides a systematic and constructive overview of ethnomedicinal uses, chemical constituents and pharmacological activities of this plant as well as future research need for its commercial utilization as nutraceutical food supplement and medicine. MATERIALS AND METHODS: This review is based on available literature on ethnomedicinal uses, phytochemical, pharmacological, toxicity and clinical studies on Cornus mas L. (cornelian cherry) fruits and other organs that was collected from electronic (SciFinder, PubMed, Science Direct and ACS among others) and library searches of books and journals. RESULTS: Versatile ethnomedicinal uses of the plant in different European and Asian countries have been reported. Phytochemical investigations on different parts of this plant have resulted in the identification of 101 compounds, among which anthocyanins, flavonoids and iridoids are the predominant groups. The crude extracts of fruits and other parts of the plant and their pure isolates exhibit a broad spectrum of pharmacological activities such as anti-microbial, anti-diabetic, anti atherosclerotic, cyto-, hepato-, neuro- and renalprotective, antiplatelet and antiglaucomic activities. Anthocyanins, flavonoids, iridoids and vitamin C are the major bioactive constituents of the fruits. Fruits are non-toxic and safe food on acute toxicity studies in rat and human models. Clinical trials in diabetic type2 and hyperlipidemic patients showed significant trends of amelioration in sugar level, insulin secretion in diabetic patients and amelioration of lipid profile, apolipoprotein status and vascular inflammation in hyperlipidemic patients. CONCLUSION: Based on our review, Cornus mas L. (cornelian cherry) fruits and leaves can be used mainly in the treatment of diabetes, obesity, atherosclerosis, skin diseases, gastrointestinal and rheumatic problems. Some indications from ethnomedicines have been validated by pharmacological activities of the fruits and its extracts/pure isolates. The reported data reveal that the fruits are a potential source for treatment of diabetes, obesity, hyperlipidemia and gastrointestinal disorders. Unfortunately, the pharmacological studies in these areas are still insufficient to substantiate these preventive effects in confirmatory trials on the mass-scale clinical settings. Future studies on mechanisms of action, bioavailability, pharmacokinetics and adverse effects of the extracts and their bioactive constituents as well as their effective doses and long term toxic effects in humans are needed for commercial applications of these extracts/isolates in modern medicines. The available literature showed that most of the activities of the extracts are due to their constituents, anthocyanins, flavonoids and other phenolics, iridoids and vitamins for their antioxidant and other properties. PMID- 27705747 TI - Vascular action of bisphosphonates: In vitro effect of alendronate on the regulation of cellular events involved in vessel pathogenesis. AB - In this work we investigate whether, despite the procalcific action of alendronate on bone, the drug would be able to regulate in vitro the main cellular events that take part in atherosclerotic lesion generation. Using endothelial cell cultures we showed that Alendronate (1-50MUM) acutely enhances nitric oxide production (10-30min). This stimulatory action of the bisphosphonate involves the participation of MAPK signaling transduction pathway. Under inflammatory stress, the drug reduces monocytes and platelets interactions with endothelial cells induced by lipopolysaccharide. Indeed the bisphophonate exhibits a significant inhibition of endothelial dependent platelet aggregation. The molecular mechanism of alendronate (ALN) on leukocyte adhesion depends on the regulation of the expression of cell adhesion related genes (VCAM-1; ICAM-1); meanwhile the antiplatelet activity is associated with the effect of the drug on nitric oxide production. On vascular smooth muscle cells, the drug exhibits ability to decrease osteogenic transdifferentiation and extracellular matrix mineralization. When vascular smooth muscle cells were cultured in osteogenic medium for 21days, they exhibited an upregulation of calcification markers (RUNX2 and TNAP), high alkaline phosphatase activity and a great amount of mineralization nodules. ALN treatment significantly down-regulates mRNA levels of osteoblasts markers; diminishes alkaline phosphatase activity and reduces the extracellular calcium deposition. The effect of ALN on vascular cells differs from its own bone action. On calvarial osteoblasts ALN induces cell proliferation, enhances alkaline phosphatase activity, and increases mineralization, but does not affect nitric oxide synthesis. Our results support the hypothesis that ALN is an active drug at vascular level that regulates key processes involved in vascular pathogenesis through a direct action on vessel cells. PMID- 27705749 TI - High GDF-15 Serum Levels Independently Correlate with Poorer Overall Survival of Patients with Tumor-Free Stage III and Unresectable Stage IV Melanoma. AB - Biomarkers are strongly needed for diagnostic surveillance of patients with metastatic melanoma. On the basis of its known association with tumor metastasis and its ability to induce cancer cachexia, we investigated serum levels of growth and differentiation factor 15 (sGDF-15) as a marker for overall survival (OS). sGDF-15 was retrospectively measured by ELISA in 761 samples obtained at distinct time points during routine clinical care of patients with stage III/IV melanoma. In the entire cohort, sGDF-15 >= 1.5 ng/ml was strongly associated with reduced OS after assessment. Subsequent analyses were performed separately for tumor-free stage III, tumor-free stage IV, and unresectable stage IV patients. For patients with unresectable distant metastasis (n = 206), sGDF-15 was independently associated with OS when considered together with the M-category and superior to serum level of lactate dehydrogenase. Analysis in tumor-free stage III patients during routine surveillance (n = 468) revealed sGDF-15 to be associated with OS and an independent factor when considered together with S100B and the pattern of locoregional metastasis. Only in tumor-free stage IV patients (n = 87) sGDF-15 was not associated with OS. sGDF-15 should thus be further validated as a marker for early detection of recurrence in stage III patients and as a prognostic or predictive marker particularly in the context newly available treatments in unresectable stage IV patients. PMID- 27705750 TI - A physiological characterization of the Cafeteria diet model of metabolic syndrome in the rat. AB - Many promising findings from pre-clinical research have failed to translate to the clinic due to their inability to incorporate human disease co-morbidity. A variety of rodent diets and feeding durations are currently used in models of human metabolic syndrome, obesity and diabetes. One model, the Cafeteria (CAF) diet, makes use of grocery store-purchased food items that more closely approximate the human ultra-processed diet than commercial high-fat or high-sugar rodent diets. The present study describes the development of metabolic syndrome in rats fed a CAF diet as well as the recovery of metabolic syndrome following a healthy "lifestyle" change. In addition, we explored the effects of CAF diet on spatial learning and memory and on neuroinflammation. Three-week old male Sprague Dawley rats were fed a CAF diet for three months that consisted of 16 highly palatable human food items along with standard chow and a 12% sucrose solution to mimic soda consumption. Thereafter, a sub-group of CAF diet rats was switched to a chow diet (SWT) for one month. Both CAF and SWT groups were compared to control rats maintained on a standard chow diet (SD). Prior to the diet switch, CAF and SWT animals developed features akin to metabolic syndrome. Both groups of rats displayed significant abdominal obesity with increased visceral adiposity, hyperinsulinemia, glucose intolerance and dyslipidemia with elevated serum triglyceride levels and reduced HDL cholesterol. Switching to a chow diet for one month completely reversed these features in SWT animals. Although acquisition of the Barnes maze was not affected by the CAF diet, these animals exhibited greater hippocampal neuroinflammation compared to both SD and SWT rats as assessed by Iba1 staining. These results demonstrate that the CAF diet is very effective in creating metabolic syndrome with hippocampal inflammation in rats over a relatively short time span. This model may be of great heuristic importance in determining potential reversibility of metabolic and cerebrovascular pathologies across the lifespan and as a co-morbid factor in other disease models such as stroke. PMID- 27705745 TI - RYBP stimulates PRC1 to shape chromatin-based communication between Polycomb repressive complexes. AB - Polycomb group (PcG) proteins function as chromatin-based transcriptional repressors that are essential for normal gene regulation during development. However, how these systems function to achieve transcriptional regulation remains very poorly understood. Here, we discover that the histone H2AK119 E3 ubiquitin ligase activity of Polycomb repressive complex 1 (PRC1) is defined by the composition of its catalytic subunits and is highly regulated by RYBP/YAF2 dependent stimulation. In mouse embryonic stem cells, RYBP plays a central role in shaping H2AK119 mono-ubiquitylation at PcG targets and underpins an activity based communication between PRC1 and Polycomb repressive complex 2 (PRC2) which is required for normal histone H3 lysine 27 trimethylation (H3K27me3). Without normal histone modification-dependent communication between PRC1 and PRC2, repressive Polycomb chromatin domains can erode, rendering target genes susceptible to inappropriate gene expression signals. This suggests that activity based communication and histone modification-dependent thresholds create a localized form of epigenetic memory required for normal PcG chromatin domain function in gene regulation. PMID- 27705746 TI - A multi-protein receptor-ligand complex underlies combinatorial dendrite guidance choices in C. elegans. AB - Ligand receptor interactions instruct axon guidance during development. How dendrites are guided to specific targets is less understood. The C. elegans PVD sensory neuron innervates muscle-skin interface with its elaborate dendritic branches. Here, we found that LECT-2, the ortholog of leukocyte cell-derived chemotaxin-2 (LECT2), is secreted from the muscles and required for muscle innervation by PVD. Mosaic analyses showed that LECT-2 acted locally to guide the growth of terminal branches. Ectopic expression of LECT-2 from seam cells is sufficient to redirect the PVD dendrites onto seam cells. LECT-2 functions in a multi-protein receptor-ligand complex that also contains two transmembrane ligands on the skin, SAX-7/L1CAM and MNR-1, and the neuronal transmembrane receptor DMA-1. LECT-2 greatly enhances the binding between SAX-7, MNR-1 and DMA 1. The activation of DMA-1 strictly requires all three ligands, which establishes a combinatorial code to precisely target and pattern dendritic arbors. PMID- 27705744 TI - Cholesterol activates the G-protein coupled receptor Smoothened to promote Hedgehog signaling. AB - Cholesterol is necessary for the function of many G-protein coupled receptors (GPCRs). We find that cholesterol is not just necessary but also sufficient to activate signaling by the Hedgehog (Hh) pathway, a prominent cell-cell communication system in development. Cholesterol influences Hh signaling by directly activating Smoothened (SMO), an orphan GPCR that transmits the Hh signal across the membrane in all animals. Unlike many GPCRs, which are regulated by cholesterol through their heptahelical transmembrane domains, SMO is activated by cholesterol through its extracellular cysteine-rich domain (CRD). Residues shown to mediate cholesterol binding to the CRD in a recent structural analysis also dictate SMO activation, both in response to cholesterol and to native Hh ligands. Our results show that cholesterol can initiate signaling from the cell surface by engaging the extracellular domain of a GPCR and suggest that SMO activity may be regulated by local changes in cholesterol abundance or accessibility. PMID- 27705751 TI - Before and after - Nutritional transformation of dysmorphism in a case of Costello syndrome. AB - Costello syndrome is a type of RASopathy mapped to HRAS gene in chromosome 11, characterized by prenatal overgrowth, postnatal failure to thrive, classic facial gestalt and multisystem involvement including cardiomyopathy and intellectual disability. We present a 7 months old child with severe failure to thrive whose "subtle" facial dysmorphism at the time eluded clinical recognition of the syndrome. It was only with optimization of his nutritional status that dysmorphic features became more apparent, which affirmed the molecular diagnosis of Costello syndrome from exome sequencing. The case illustrated how drastic failure to thrive can be in Costello syndrome, and how nutritional status can transform dysmorphic features in a child. It also highlights the importance of serial dysmorphic evaluation in difficult cases.

AB - Mammals of the Neotropics are characterized by a marked annual cycle of activity, which is accompanied by several physiological changes at the levels of the whole organism, organs and tissues. The physiological characterization of these cycles is important, as it gives insight on the mechanisms by which animals adjust adaptively to seasonality. Here we studied the seasonal changes in blood biochemical parameters in the relict South American marsupial Dromiciops gliroides ("monito del monte" or "little mountain monkey"), under semi-natural conditions. We manipulated thermal conditions in order to characterize the effects of temperature and season on a battery of biochemical parameters, body mass and adiposity. Our results indicate that monitos experience an annual cycle in body mass and adiposity (measured as leptin levels), reaching a maximum in winter and a minimum in summer. Blood biochemistry confirms that the nutritional condition of animals is reduced in summer instead of winter (as generally reported). This was coincident with a reduction of several biochemical parameters in summer, such as betahydroxybutyrate, cholesterol, total protein concentration and globulins. Monitos seem to initiate winter preparation during autumn and reach maximum body reserves in winter. Hibernation lasts until spring, at which time they use fat reserves and become reproductively active. Sexual maturation during summer would be the strongest energetic bottleneck, which explains the reductions in body mass and other parameters in this season. Overall, this study suggests that monitos anticipate the cold season by a complex interaction of photoperiodic and thermal cues.

AB - Phytochemical investigation on the whole plant of Chloranthus japonicus (Chloranthaceae) led to the isolation and identification of three new lindenane type sesquiterpenoid dimers, chlorajaponilides F-H (1-3), along with seven known ones (4-10). Their chemical structures were established by extensive spectral evidence. Compounds 1 and 2 are both dimeric sesquiterpenoids featuring a rare hydroperoxy group at C-5. All compounds were tested for their activities on wild type HIV-1 replication and compounds 1, 2, 5, and 9 were effective with EC50 values from 3.08 to 17.16MUM. All these four compounds showed the same inhibitory effects on the two NNRTI-resistant HIV strains as on wild-type HIV-1 with EC50 change folds from 0.61 to 1.6MUM. Furthermore, compounds 1, 5, and 9 exhibited inhibitory activities on HCV replication with the similar potency as their activities on HIV-1. Our finding may provide a clue to address the problem of HIV 1 and HCV co-infection. PMID- 27705756 TI - Epicardial fat is associated with severity of subclinical coronary atherosclerosis in familial hypercholesterolemia. AB - BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a common genetic disorder characterized by elevated blood cholesterol, increased prevalence of subclinical atherosclerosis and high risk of premature coronary heart disease. However, this risk is not explained solely by elevated LDL-cholesterol concentrations, and other factors may influence atherosclerosis development. There is evidence that increased adiposity may predispose to atherosclerosis in FH. Epicardial fat has been associated with subclinical coronary atherosclerosis in the general population. This study evaluated the association of epicardial fat (EFV) volume with the presence and extent of subclinical coronary atherosclerosis detected by computed tomography angiography in FH patients. METHODS: Ninety-seven FH subjects (35% male, mean age 45 +/- 13 years, LDL-C 281 +/- 56 mg/dL, 67% with proven molecular defects) underwent computed tomography angiography and coronary artery calcium (CAC) scoring. EFV was measured in non-contrast images using a semi-automated method. Segment-stenosis score (SSS) and segment-involvement score (SIS) were calculated. Multivariate Poisson regression was utilized to assess an independent association of EFV with coronary atherosclerotic burden. RESULTS: EFV was positively associated with age, body mass index, waist circumference, blood glucose, the presence of the metabolic syndrome components, but not with LDL-C. After adjusting for confounders and abdominal circumference, an independent association (shown as beta coefficients and 95% confidence intervals) of EVF with CAC scores [beta = 0.263 (0.234; 0.292), p=0.000], SIS [beta = 0.304 (0.141; 0.465) p=0.000] and SSS [beta = 0.296 (0.121; 0.471), p=0.001] was found. CONCLUSIONS: In FH, EFV was independently associated with coronary atherosclerotic presence and severity. PMID- 27705754 TI - The effect of l-thymidine, acyclic thymine and 8-bromoguanine on the stability of model G-quadruplex structures. AB - BACKGROUND: Guanine-rich oligonucleotides are capable of forming tetrahelical structures known as G-quadruplexes with interesting biological properties. We have investigated the effects of site-specific substitution in the loops and in the tetrads model G-quadruplexes using thymine glycol nucleic acid (GNA) units, l thymidine and 8-Br-2'-deoxyguanosine. METHODS: Modified oligonucleotides were chemically synthesized and spectroscopic techniques were used to determine the relative stability of the modified G-quadruplex. The double 8-BrdG-modified quadruplexes were further characterized by Nuclear Magnetic Resonance. Binding to thrombin of selected quadruplex was analyzed by gel electrophoresis retention assay. RESULTS: The most interesting results were found with a 8-bromoG substitution that had the larger stabilization of the quadruplex. NMR studies indicate a tight relationship between the loops and the tetrads to accommodate 8 bromoG modifications within the TBA. CONCLUSIONS: The substitutions of loop positions with GNA T affect the TBA stability except for single modification in T7 position. Single l-thymidine substitutions produced destabilization of TBA. Larger changes on quadruplex stability are observed with the use of 8-bromoG finding a single substitution with the highest thermal stabilization found in thrombin binding aptamers modified at the guanine residues and having good affinity for thrombin. Double 8-BrdG modification in anti positions of different tetrads produce a conformational flip from syn to anti conformation of 8-Br-dG to favor loop-tetrad interaction and preserve the overall TBA stability. GENERAL SIGNIFICANCE: Modified guanine-rich oligonucleotides are valuable tools for the search for G-quadruplex structures with higher thermal stability and may provide compounds with interesting protein-nucleic acid binding properties.

AB - Topological constraints, such as those associated with DNA supercoiling, play an integral role in genomic regulation and organization in living systems. However, physical understanding of the principles that underlie DNA organization at biologically relevant length scales remains a formidable challenge. We develop a coarse-grained simulation approach for predicting equilibrium conformations of supercoiled DNA. Our methodology enables the study of supercoiled DNA molecules at greater length scales and supercoiling densities than previously explored by simulation. With this approach, we study the conformational transitions that arise due to supercoiling across the full range of supercoiling densities that are commonly explored by living systems. Simulations of ring DNA molecules with lengths at the scale of topological domains in the Escherichia coli chromosome (~10 kilobases) reveal large-scale conformational transitions elicited by supercoiling. The conformational transitions result in three supercoiling conformational regimes that are governed by a competition among chiral coils, extended plectonemes, and branched hyper-supercoils. These results capture the nonmonotonic relationship of size versus degree of supercoiling observed in experimental sedimentation studies of supercoiled DNA, and our results provide a physical explanation of the conformational transitions underlying this behavior. The length scales and supercoiling regimes investigated here coincide with those relevant to transcription-coupled remodeling of supercoiled topological domains, and we discuss possible implications of these findings in terms of the interplay between transcription and topology in bacterial chromosome organization.

AB - Bulky cations are used to develop nucleic-acid-based technologies for medical and technological applications in which nucleic acids function under nonaqueous conditions. In this study, the thermal stability of RNA structures was measured in the presence of various bulky cations in aqueous mixtures with organic solvents or polymer additives. The stability of oligonucleotide, transfer RNA, and polynucleotide structures was decreased in the presence of salts of tetrabutylammonium and tetrapentylammonium ions, and the stability and salt concentration dependences were dependent on cation sizes. The degree to which stability was dependent on salt concentration was correlated with reciprocals of the dielectric constants of mixed solutions, regardless of interactions between the cosolutes and RNA. Our results show that organic solvents affect the strength of electrostatic interactions between RNA and cations. Analysis of ion binding to RNA indicated greater enhancement of cation binding to RNA single strands than to duplexes in media with low dielectric constants. Furthermore, background bulky ions changed the dependence of RNA duplex stability on the concentration of metal ion salts. These unique properties of large tetraalkylammonium ions are useful for controlling the stability of RNA structures and its sensitivity to metal ion salts. PMID- 27705752 TI - SOX2, OCT3/4 and NANOG expression and cellular plasticity in rare human somatic cells requires CD73. AB - Endogenous Plastic Somatic (ePS) cells isolated from adult human tissues exhibit extensive lineage plasticity in vitro and in vivo. Here we visualize these rare ePS cells in a latent state, i.e. lacking SOX2, OCT3/4 and NANOG (SON) expression, in non-diseased breast specimens through immunohistochemical analysis of previously identified ePS-specific biomarkers (CD73+, EpCAM+ and CD90-). We also report a novel mechanism by which these latent ePS cells acquire SON expression and plasticity in vitro. Four extracellular factors are necessary for the acquisition of SON expression and lineage plasticity in ePS cells: adenosine (which is produced by the 5' ecto-nucleotidase CD73 and activates in turn the PKA dependent IL6/STAT3 pathway through the adenosine receptor ADORA2b), IL6, FGF2 and ACTIVIN A. Blocking any pathway component renders ePS cells incapable of SON expression and lineage plasticity. Notably, hESCs do not use adenosine or IL6 nor they express CD73 or ADORA2b and inhibition of adenosine signaling does not ablate their plasticity. Therefore, the data presented here delineate novel circuitry and physiological signals for accessing SON expression in rare, undifferentiated human cells. PMID- 27705761 TI - Single-Molecule Analysis beyond Dwell Times: Demonstration and Assessment in and out of Equilibrium. AB - We present a simple and robust technique for extracting kinetic rate models and thermodynamic quantities from single-molecule time traces. Single-molecule analysis of complex kinetic sequences (SMACKS) is a maximum-likelihood approach that resolves all statistically relevant rates and also their uncertainties. This is achieved by optimizing one global kinetic model based on the complete data set while allowing for experimental variations between individual trajectories. In contrast to dwell-time analysis, which is the current standard method, SMACKS includes every experimental data point, not only dwell times. As a result, it works as well for long trajectories as for an equivalent set of short ones. In addition, the previous systematic overestimation of fast over slow rates is solved. We demonstrate the power of SMACKS on the kinetics of the multidomain protein Hsp90 measured by single-molecule Forster resonance energy transfer. Experiments in and out of equilibrium are analyzed and compared to simulations, shedding new light on the role of Hsp90's ATPase function. SMACKS resolves accurate rate models even if states cause indistinguishable signals. Thereby, it pushes the boundaries of single-molecule kinetics beyond those of current methods. PMID- 27705760 TI - Imaging the Nonlinear Susceptibility Tensor of Collagen by Nonlinear Optical Stokes Ellipsometry. AB - Nonlinear optical Stokes ellipsometric (NOSE) microscopy was demonstrated for the analysis of collagen-rich biological tissues. NOSE is based on polarization dependent second harmonic generation imaging. NOSE was used to access the molecular-level distribution of collagen fibril orientation relative to the local fiber axis at every position within the field of view. Fibril tilt-angle distribution was investigated by combining the NOSE measurements with ab initio calculations of the predicted molecular nonlinear optical response of a single collagen triple helix. The results were compared with results obtained previously by scanning electron microscopy, nuclear magnetic resonance imaging, and electron tomography. These results were enabled by first measuring the laboratory-frame Jones nonlinear susceptibility tensor, then extending to the local-frame tensor through pixel-by-pixel corrections based on local orientation. PMID- 27705762 TI - Urea-Dependent Adenylate Kinase Activation following Redistribution of Structural States. AB - Proteins are often functionally dependent on conformational changes that allow them to sample structural states that are sparsely populated in the absence of a substrate or binding partner. The distribution of such structural microstates is governed by their relative stability, and the kinetics of their interconversion is governed by the magnitude of associated activation barriers. Here, we have explored the interplay among structure, stability, and function of a selected enzyme, adenylate kinase (Adk), by monitoring changes in its enzymatic activity in response to additions of urea. For this purpose we used a 31P NMR assay that was found useful for heterogeneous sample compositions such as presence of urea. It was found that Adk is activated at low urea concentrations whereas higher urea concentrations unfolds and thereby deactivates the enzyme. From a quantitative analysis of chemical shifts, it was found that urea redistributes preexisting structural microstates, stabilizing a substrate-bound open state at the expense of a substrate-bound closed state. Adk is rate-limited by slow opening of substrate binding domains and the urea-dependent redistribution of structural states is consistent with a model where the increased activity results from an increased rate-constant for domain opening. In addition, we also detected a strong correlation between the catalytic free energy and free energy of substrate (ATP) binding, which is also consistent with the catalytic model for Adk. From a general perspective, it appears that urea can be used to modulate conformational equilibria of folded proteins toward more expanded states for cases where a sizeable difference in solvent-accessible surface area exists between the states involved. This effect complements the action of osmolytes, such as trimethylamine N-oxide, that favor more compact protein states. PMID- 27705763 TI - A Novel Voltage Sensor in the Orthosteric Binding Site of the M2 Muscarinic Receptor. AB - G protein-coupled receptors (GPCRs) mediate many signal transduction processes in the body. The discovery that these receptors are voltage-sensitive has changed our understanding of their behavior. The M2 muscarinic acetylcholine receptor (M2R) was found to exhibit depolarization-induced charge movement-associated currents, implying that this prototypical GPCR possesses a voltage sensor. However, the typical domain that serves as a voltage sensor in voltage-gated channels is not present in GPCRs, making the search for the voltage sensor in the latter challenging. Here, we examine the M2R and describe a voltage sensor that is comprised of tyrosine residues. This voltage sensor is crucial for the voltage dependence of agonist binding to the receptor. The tyrosine-based voltage sensor discovered here constitutes a noncanonical by which membrane proteins may sense voltage. PMID- 27705765 TI - Semiclosed Conformations of the Ligand-Binding Domains of NMDA Receptors during Stationary Gating. AB - NMDA receptors are tetrameric ligand-gated ion channels. In the continuous presence of saturating agonists, NMDA receptors undergo stationary gating, in which the channel stochastically switches between an open state that permits ion conductance and a closed state that prevents permeation. The ligand-binding domains (LBDs) of the four subunits are expected to have closed clefts in the channel-open state. On the other hand, there is little knowledge about the conformational status of the LBDs in the channel-closed state during stationary gating. To probe the latter conformational status, Kussius and Popescu engineered interlobe disulfide cross-links in NMDA receptors and found that the cross linking produced stationary gating kinetics that differed only subtly from that produced by agonist binding. These authors assumed that the cross-linking immobilized the LBDs in cleft-closed conformations, and consequently concluded that throughout stationary gating, agonist-bound LBDs also stayed predominantly in cleft-closed conformations and made only infrequent excursions to cleft-open conformations. Here, by calculating the conformational free energies of cross linked and agonist-bound LBDs, we assess whether cross-linking actually traps the LBDs in cleft-closed conformations and delineate semiclosed conformations of agonist-bound LBDs that may potentially be thermodynamically and kinetically important during stationary gating. Our free-energy results show that the cross linked LBDs are not locked in the fully closed form; rather, they sample semiclosed conformations almost as readily as the agonist-bound LBDs. Several lines of reasoning suggest that LBDs are semiclosed in the channel-closed state during stationary gating. Our free-energy simulations suggest possible structural details of such semiclosed LBD conformations, including intra- and intermolecular interactions that serve as alternatives to those in the cleft-closed conformations. PMID- 27705764 TI - Role of the Native Outer-Membrane Environment on the Transporter BtuB. AB - BtuB is a TonB-dependent transporter that permits the high-affinity binding and transport of cobalamin (CBL), or vitamin B12, across the asymmetric outer membrane (OM) of Gram-negative bacteria. It has been shown that Ca2+ binding is necessary for high-affinity binding of CBL to BtuB, and earlier simulations suggested that calcium ions serve to stabilize key substrate-binding extracellular loops. However, those simulations did not account for the lipopolysaccharides in the OM. To illuminate the roles of both Ca2+ and lipopolysaccharides in protein functionality, we performed simulations of apo and Ca2+-loaded BtuB in symmetric and asymmetric bilayers. The simulations reveal that the oligosaccharides of LPS stabilize the extracellular loops to some degree, apparently obviating the need for Ca2+. However, it is shown that Ca2+ ions stabilize a key substrate-binding loop to an even greater degree, as well as reposition specific CBL-binding residues, bringing them closer to the organization found in the CBL-bound structure. These results indicate the importance of including realistic membrane models when simulating outer-membrane proteins. PMID- 27705766 TI - Investigation of LRRC8-Mediated Volume-Regulated Anion Currents in Xenopus Oocytes. AB - Volume-regulated anion channels (VRACs) play an important role in controlling cell volume by opening upon cell swelling. Recent work has shown that heteromers of LRRC8A with other LRRC8 members (B, C, D, and E) form the VRAC. Here, we used Xenopus oocytes as a simple system to study LRRC8 proteins. We discovered that adding fluorescent proteins to the C-terminus resulted in constitutive anion channel activity. Using these constructs, we reproduced previous findings indicating that LRRC8 heteromers mediate anion and osmolyte flux with subunit dependent kinetics and selectivity. Additionally, we found that LRRC8 heteromers mediate glutamate and ATP flux and that the inhibitor carbenoxolone acts from the extracellular side, binding to probably more than one site. Our results also suggest that the stoichiometry of LRRC8 heteromers is variable, with a number of subunits >=6, and that the heteromer composition depends on the relative expression of different subunits. The system described here enables easy structure-function analysis of LRRC8 proteins. PMID- 27705767 TI - Binding of Vinculin to Lipid Membranes in Its Inhibited and Activated States. AB - Phosphoinositols are an important class of phospholipids that are involved in a myriad of cellular processes, from cell signaling to motility and adhesion. Vinculin (Vn) is a major adaptor protein that regulates focal adhesions in conjunction with PIP2 in lipid membranes and other cytoskeletal components. The binding and unbinding transitions of Vn at the membrane interface are an important link to understanding the coordination of cell signaling and motility. Using different biophysical tools, including atomic force microscopy combined with confocal fluorescence microscopy and Fourier transform infrared spectroscopy, we studied the nanoscopic interactions of activated and autoinhibited states of Vn with lipid membranes. We hypothesize that a weak interaction occurs between Vn and lipid membranes, which leads to binding of autoinhibited Vn to supported lipid bilayers, and to unbinding in freestanding lipid vesicles. Likely driving forces may include tethering of the C-terminus to the lipid membrane, as well as hydrophobic helix-membrane interactions. Conversely, activated Vn binds strongly to membranes through specific interactions with clusters of PIP2 embedded in lipid membranes. Activated Vn harbored on PIP2 clusters may form small oligomeric interaction platforms for further interaction partners, which is necessary for the proper function of focal adhesion points. PMID- 27705768 TI - Modulating Vesicle Adhesion by Electric Fields. AB - We introduce an experimental setup for modulating adhesion of giant unilamellar vesicles to a planar substrate. Adhesion is induced by the application of an external potential to a transparent indium tin oxide-coated electrode (the substrate), which enables single-vesicle studies. We demonstrate tunable and reversible adhesion of negatively charged vesicles. The adhesion energy at different potentials is calculated from the vesicle shape assessed with confocal microscopy. Two approaches for these estimates are employed: one based on the whole contour of the vesicle and a second based on the contact curvature of the membrane in the vicinity of the substrate. Both approaches agree well with each other and show that the adhering vesicles are in the weak adhesion regime for the range of explored external potentials. Using fluorescence quenching assays, we detect that, in the adhering membrane segment, only the outer bilayer leaflet of the vesicle is depleted of negatively charged fluorescent lipids, while the inner leaflet remains unaffected. We show that depletion of negatively charged lipids is consistent Poisson-Boltzmann theory, taking into account charge regulation from lipid mobility. Finally, we also show that lipid diffusion is not significantly affected in the adhering membrane segment. We believe that the approaches introduced here for modulating and assessing vesicle adhesion have many potential applications in the field of single-vesicle studies and research on membrane adhesion. PMID- 27705770 TI - A Tensegrity Model of Cell Reorientation on Cyclically Stretched Substrates. AB - Deciphering the mechanisms underlying the high sensitivity of cells to mechanical microenvironments is crucial for understanding many physiological and pathological processes, e.g., stem cell differentiation and cancer cell metastasis. Here, a cytoskeletal tensegrity model is proposed to study the reorientation of polarized cells on a substrate under biaxial cyclic deformation. The model consists of four bars, representing the longitudinal stress fibers and lateral actin network, and eight strings, denoting the microfilaments. It is found that the lateral bars in the tensegrity, which have been neglected in most of the existing models, can play a vital role in regulating the cellular orientation. The steady orientation of cells can be quantitatively determined by the geometric dimensions and elastic properties of the tensegrity elements, as well as the frequency and biaxial ratio of the cyclic stretches. It is shown that this tensegrity model can reproduce all available experimental observations. For example, the dynamics of cell reorientation is captured by an exponential scaling law with a characteristic time that is independent of the loading frequency at high frequencies and scales inversely with the square of the strain amplitude. This study suggests that tensegrity type models may be further developed to understand cellular responses to mechanical microenvironments and provide guidance for engineering delicate cellular mechanosensing systems. PMID- 27705771 TI - Direct Tracking of Particles and Quantification of Margination in Blood Flow. AB - Margination refers to the migration of particles toward blood vessel walls during blood flow. Understanding the mechanisms that lead to margination will aid in tailoring the attributes of drug-carrying particles for effective drug delivery. Most previous studies evaluated the margination propensity of these particles via an adhesion mechanism, i.e., by measuring the number of particles that adhered to the channel wall. Although particle adhesion and margination are related, adhesion also depends on other factors. In this study, we quantified the margination propensity of particles of varying diameters (0.53, 0.84, and 2.11 MUm) and apparent wall shear rates (30, 61, and 121 s-1) by directly tracking fluorescent particles flowing through a microfluidic channel. The margination parameter, M, is defined as the total number of particles found within the cell free layers normalized by the total number of particles that passed through the channel. In this study, an M-value of 0.2 indicated no margination, which was observed for all particle sizes in water. In the case of blood, larger particles were found to have higher M-values and thus marginated more effectively than smaller particles. The corresponding M-values at the device outlet were 0.203, 0.223, and 0.285 for 0.53-, 0.84-, and 2.11-MUm particles, respectively. At the inlet, the M-values for all particle sizes in blood were <0.2, suggesting that non-fully-developed flow and constriction may lead to demargination. For particle velocities transverse to the flow direction (vy), all particle sizes showed a larger standard deviation of vy as well as a higher effective diffusivity when the particles were suspended in blood relative to water. These higher values are attributed to collisions between the blood cells and particles, further supporting recent simulation results. In terms of flow rates, for a given particle size, the higher the flow rate, the higher the M-value. PMID- 27705772 TI - Scattering of Cell Clusters in Confinement. AB - Epithelial-to-mesenchymal transition (EMT) enables scattering of cell clusters and disseminates motile cells to distant locations in vivo during embryonic development and cancer metastasis. Both stiffness and topography of the extracellular matrix (ECM) have been shown to influence EMT. In this work, we examine how the integrity of epithelial cell clusters is regulated by subcellular forces, protrusions, and adhesions for varying ECM inputs, such as stiffness, topography, and dimensionality. Our model simulates multicell networks of defined sizes and shapes in ECMs of varied stiffness and geometry. The integrity of cell clusters is dictated by cell-cell junctions, which depend on subcellular forces and adhesion dynamics within each cell of the cluster. Our simulations demonstrate an enhanced dissociation of cell-cell junctions in stiffer and more confined three-dimensional (3D) environments, consistent with experimental findings. In narrow channels, the cell edges parallel to the axis of channels lose their cell-cell junctions more readily than those oriented in the perpendicular direction. The inhibition of protrusive activity and cell polarity disables confinement-dependent cell scattering. Here, cell adhesion and spreading along channel walls is found to be essential for scattering. The model also predicts that two-dimensional (2D) confinement of clusters restricts cell spreading and simultaneously blunts the confinement-sensitive cell scattering. This new, to our knowledge, multiscale model integrates molecular adhesion dynamics, subcellular forces, cellular deformation, and macroscale mechanical properties of the ECM to predict the state of cell clusters of defined shapes and sizes. The predictions made by our model not only match experimental findings from a number of experimental setups, but also provide a new conceptual framework for understanding mechanosensitive cell scattering and EMT. PMID- 27705769 TI - Myosin-Induced Gliding Patterns at Varied [MgATP] Unveil a Dynamic Actin Filament. AB - Actin filaments have key roles in cell motility but are generally claimed to be passive interaction partners in actin-myosin-based motion generation. Here, we present evidence against this static view based on an altered myosin-induced actin filament gliding pattern in an in vitro motility assay at varied [MgATP]. The statistics that characterize the degree of meandering of the actin filament paths suggest that for [MgATP] >= 0.25 mM, the flexural rigidity of heavy meromyosin (HMM)-propelled actin filaments is similar (without phalloidin) or slightly lower (with phalloidin) than that of HMM-free filaments observed in solution without surface tethering. When [MgATP] was reduced to <=0.1 mM, the actin filament paths in the in vitro motility assay became appreciably more winding in both the presence and absence of phalloidin. This effect of lowered [MgATP] was qualitatively different from that seen when HMM was mixed with ATP insensitive, N-ethylmaleimide-treated HMM (NEM-HMM; 25-30%). In particular, the addition of NEM-HMM increased a non-Gaussian tail in the path curvature distribution as well as the number of events in which different parts of an actin filament followed different paths. These effects were the opposite of those observed with reduced [MgATP]. Theoretical modeling suggests a 30-40% lowered flexural rigidity of the actin filaments at [MgATP] <= 0.1 mM and local bending of the filament front upon each myosin head attachment. Overall, the results fit with appreciable structural changes in the actin filament during actomyosin-based motion generation, and modulation of the actin filament mechanical properties by the dominating chemomechanical actomyosin state. PMID- 27705775 TI - Measuring the Viscosity of the Escherichia coli Plasma Membrane Using Molecular Rotors. AB - The viscosity is a highly important parameter within the cell membrane, affecting the diffusion of small molecules and, hence, controlling the rates of intracellular reactions. There is significant interest in the direct, quantitative assessment of membrane viscosity. Here we report the use of fluorescence lifetime imaging microscopy of the molecular rotor BODIPY C10 in the membranes of live Escherichia coli bacteria to permit direct quantification of the viscosity. Using this approach, we investigated the viscosity in live E. coli cells, spheroplasts, and liposomes made from E. coli membrane extracts. For live cells and spheroplasts, the viscosity was measured at both room temperature (23 degrees C) and the E. coli growth temperature (37 degrees C), while the membrane extract liposomes were studied over a range of measurement temperatures (5-40 degrees C). At 37 degrees C, we recorded a membrane viscosity in live E. coli cells of 950 cP, which is considerably higher than that previously observed in other live cell membranes (e.g., eukaryotic cells, membranes of Bacillus vegetative cells). Interestingly, this indicates that E. coli cells exhibit a high degree of lipid ordering within their liquid-phase plasma membranes. PMID- 27705777 TI - Unified Theory for Polarization Analysis in Second Harmonic and Sum Frequency Microscopy. AB - A unified theoretical framework for the recovery of second-order nonlinear susceptibility tensors and sample orientations from polarization-dependent second harmonic generation and sum frequency generation microscopy was developed. Jones formalism was extended to nonlinear optics and was used to bridge the experimental observables and the local-frame tensor elements. Four commonly used experimental architectures were explicitly explored, including polarization rotation with no postsample optics, polarization-in polarization-out measurement, and polarization modulation with and without postsample optics. Polarization dependent second harmonic generation measurement was performed on Z-cut quartz and the local-frame tensor elements were calculated. The recovered tensor elements agree with the expected values dictated by symmetry. PMID- 27705778 TI - Positive Quantitative Relationship between EMT and Contact-Initiated Sliding on Fiber-like Tracks. AB - Epithelial-mesenchymal transition (EMT) is a complex process by which cells acquire invasive properties that enable escape from the primary tumor. Complete EMT, however, is not required for metastasis: circulating tumor cells exhibit hybrid epithelial-mesenchymal states, and genetic perturbations promoting partial EMT induce metastasis in vivo. An open question is whether and to what extent intermediate stages of EMT promote invasiveness. Here, we investigate this question, building on recent observation of a new invasive property. Migrating cancer cell lines and cells transduced with prometastatic genes slide around other cells on spatially confined, fiberlike micropatterns. We show here that low dosage/short-duration exposure to transforming growth factor beta (TGFbeta) induces partial EMT and enables sliding on narrower (26 MUm) micropatterns than untreated counterparts (41 MUm). High-dosage/long-duration exposure induces more complete EMT, including disrupted cell-cell contacts and reduced E-cadherin expression, and promotes sliding on the narrowest (15 MUm) micropatterns. These results identify a direct and quantitative relationship between EMT and cell sliding and show that EMT-associated invasive sliding is progressive, with cells that undergo partial EMT exhibiting intermediate sliding behavior and cells that transition more completely through EMT displaying maximal sliding. Our findings suggest a model in which fiber maturation and EMT work synergistically to promote invasiveness during cancer progression. PMID- 27705774 TI - Mechanism of Axonal Contractility in Embryonic Drosophila Motor Neurons In Vivo. AB - Several in vitro and limited in vivo experiments have shown that neurons maintain a rest tension along their axons intrinsically. They grow in response to stretch but contract in response to loss of tension. This contraction eventually leads to the restoration of the rest tension in axons. However, the mechanism by which axons maintain tension in vivo remains elusive. The objective of this work is to elucidate the key cytoskeletal components responsible for generating tension in axons. Toward this goal, in vivo experiments were conducted on single axons of embryonic Drosophila motor neurons in the presence of various drugs. Each axon was slackened mechanically by bringing the neuromuscular junction toward the central nervous system multiple times. In the absence of any drug, axons shortened and restored the straight configuration within 2-4 min of slackening. The total shortening was ~40% of the original length. The recovery rate in each cycle, but not the recovery magnitude, was dependent on the axon's prior contraction history. For example, the contraction time of a previously slackened axon may be twice its first-time contraction. This recovery was significantly hampered with the depletion of ATP, inhibition of myosin motors, and disruption of actin filaments. The disruption of microtubules did not affect the recovery magnitude, but, on the contrary, led to an enhanced recovery rate compared to control cases. These results suggest that the actomyosin machinery is the major active element in axonal contraction, whereas microtubules contribute as resistive/dissipative elements. PMID- 27705779 TI - Shape Selection of Surface-Bound Helical Filaments: Biopolymers on Curved Membranes. AB - Motivated to understand the behavior of biological filaments interacting with membranes of various types, we employ a theoretical model for the shape and thermodynamics of intrinsically helical filaments bound to curved membranes. We show that filament-surface interactions lead to a host of nonuniform shape equilibria, in which filaments progressively unwind from their native twist with increasing surface interaction and surface curvature, ultimately adopting uniform contact curved shapes. The latter effect is due to nonlinear coupling between elastic twist and bending of filaments on anisotropically curved surfaces such as the cylindrical surfaces considered here. Via a combination of numerical solutions and asymptotic analysis of shape equilibria, we show that filament conformations are critically sensitive to the surface curvature in both the strong- and weak-binding limits. These results suggest that local structure of membrane-bound chiral filaments is generically sensitive to the curvature radius of the surface to which it is bound, even when that radius is much larger than the filament's intrinsic pitch. Typical values of elastic parameters and interaction energies for several prokaryotic and eukaryotic filaments indicate that biopolymers are inherently very sensitive to the coupling between twist, interactions, and geometry and that this could be exploited for regulation of a variety of processes such as the targeted exertion of forces, signaling, and self assembly in response to geometric cues including the local mean and Gaussian curvatures.

AB - Cadherin is a cell-surface transmembrane receptor that mediates calcium-dependent cell-cell adhesion and is a major component of adhesive junctions. The formation of intercellular adhesive junctions is initiated by trans binding between cadherins on adjacent cells, which is followed by the clustering of cadherins via the formation of cis interactions between cadherins on the same cell membranes. Moreover, classical cadherins have multiple glycosylation sites along their extracellular regions. It was found that aberrant glycosylation affects the adhesive function of cadherins and correlates with metastatic phenotypes of several cancers. However, a mechanistic understanding of cadherin clustering during cell adhesion and the role of glycosylation in this process is still lacking. Here, we designed a kinetic model that includes multistep reaction pathways for cadherin clustering. We further applied a diffusion-reaction algorithm to numerically simulate the clustering process using a recently developed coarse-grained model. Using experimentally measured rates of trans binding between soluble E-cadherin extracellular domains, we conducted simulations of cadherin-mediated cell-cell binding kinetics, and the results are quantitatively comparable to experimental data from micropipette experiments. In addition, we show that incorporating cadherin clustering via cis interactions further increases intercellular binding. Interestingly, a two-phase kinetic profile was derived under the assumption that glycosylation regulates the kinetic rates of cis interactions. This two-phase profile is qualitatively consistent with experimental results from micropipette measurements. Therefore, our computational studies provide new, to our knowledge, insights into the molecular mechanism of cadherin-based cell adhesion.

PMID- 27705776 TI - A Chemomechanical Model for Nuclear Morphology and Stresses during Cell Transendothelial Migration. AB - It is now evident that the cell nucleus undergoes dramatic shape changes during important cellular processes such as cell transmigration through extracellular matrix and endothelium. Recent experimental data suggest that during cell transmigration the deformability of the nucleus could be a limiting factor, and the morphological and structural alterations that the nucleus encounters can perturb genomic organization that in turn influences cellular behavior. Despite its importance, a biophysical model that connects the experimentally observed nuclear morphological changes to the underlying biophysical factors during transmigration through small constrictions is still lacking. Here, we developed a universal chemomechanical model that describes nuclear strains and shapes and predicts thresholds for the rupture of the nuclear envelope and for nuclear plastic deformation during transmigration through small constrictions. The model includes actin contraction and cytosolic back pressure that squeeze the nucleus through constrictions and overcome the mechanical resistance from deformation of the nucleus and the constrictions. The nucleus is treated as an elastic shell encompassing a poroelastic material representing the nuclear envelope and inner nucleoplasm, respectively. Tuning the chemomechanical parameters of different components such as cell contractility and nuclear and matrix stiffnesses, our model predicts the lower bounds of constriction size for successful transmigration. Furthermore, treating the chromatin as a plastic material, our model faithfully reproduced the experimentally observed irreversible nuclear deformations after transmigration in lamin-A/C-deficient cells, whereas the wild type cells show much less plastic deformation. Along with making testable predictions, which are in accord with our experiments and existing literature, our work provides a realistic framework to assess the biophysical modulators of nuclear deformation during cell transmigration. PMID- 27705782 TI - Stargazin Modulation of AMPA Receptors. AB - Fast excitatory synaptic signaling in the mammalian brain is mediated by AMPA type ionotropic glutamate receptors. In neurons, AMPA receptors co-assemble with auxiliary proteins, such as stargazin, which can markedly alter receptor trafficking and gating. Here, we used luminescence resonance energy transfer measurements to map distances between the full-length, functional AMPA receptor and stargazin expressed in HEK293 cells and to determine the ensemble structural changes in the receptor due to stargazin. In addition, we used single-molecule fluorescence resonance energy transfer to study the structural and conformational distribution of the receptor and how this distribution is affected by stargazin. Our nanopositioning data place stargazin below the AMPA receptor ligand-binding domain, where it is well poised to act as a scaffold to facilitate the long-range conformational selection observations seen in single-molecule experiments. These data support a model of stargazin acting to stabilize or select conformational states that favor activation. PMID- 27705783 TI - A Switch in Thermal Preference in Drosophila Larvae Depends on Multiple Rhodopsins. AB - Drosophila third-instar larvae exhibit changes in their behavioral responses to gravity and food as they transition from feeding to wandering stages. Using a thermal gradient encompassing the comfortable range (18 degrees C to 28 degrees C), we found that third-instar larvae exhibit a dramatic shift in thermal preference. Early third-instar larvae prefer 24 degrees C, which switches to increasingly stronger biases for 18 degrees C-19 degrees C in mid- and late-third instar larvae. Mutations eliminating either of two rhodopsins, Rh5 and Rh6, wiped out these age-dependent changes in thermal preference. In larvae, Rh5 and Rh6 are thought to function exclusively in the light-sensing Bolwig organ. However, the Bolwig organ was dispensable for the thermal preference. Rather, Rh5 and Rh6 were required in trpA1-expressing neurons in the brain, ventral nerve cord, and body wall. Because Rh1 contributes to thermal selection in the comfortable range during the early to mid-third-instar stage, fine thermal discrimination depends on multiple rhodopsins. PMID- 27705784 TI - Hierarchical Size Scaling during Multicellular Growth and Development. AB - Multicellular organisms must regulate their growth across the diverse length scales of biological organization, but how this growth is controlled from organelle to body, while coordinating interdependent functions at each scale, remains poorly understood. We utilized the C. elegans worm intestine as a model system to identify distinct allometric scaling laws, revealing that the growth of individual structures is differentially regulated during development. We show that the volume of the nucleolus, a subcellular organelle, is directly proportional (isometric) to cell size during larval development. In contrast to findings in a variety of other systems, the size of the nucleus grows more slowly and is hypoallometric to the cell. We further demonstrate that the relative size of the nucleolus, the site of ribosome biogenesis, is predictive of the growth rate of the entire worm. These results highlight the importance of subcellular size for organism-level function in multicellular organisms. PMID- 27705781 TI - Loss of Dendritic Complexity Precedes Neurodegeneration in a Mouse Model with Disrupted Mitochondrial Distribution in Mature Dendrites. AB - Correct mitochondrial distribution is critical for satisfying local energy demands and calcium buffering requirements and supporting key cellular processes. The mitochondrially targeted proteins Miro1 and Miro2 are important components of the mitochondrial transport machinery, but their specific roles in neuronal development, maintenance, and survival remain poorly understood. Using mouse knockout strategies, we demonstrate that Miro1, as opposed to Miro2, is the primary regulator of mitochondrial transport in both axons and dendrites. Miro1 deletion leads to depletion of mitochondria from distal dendrites but not axons, accompanied by a marked reduction in dendritic complexity. Disrupting postnatal mitochondrial distribution in vivo by deleting Miro1 in mature neurons causes a progressive loss of distal dendrites and compromises neuronal survival. Thus, the local availability of mitochondrial mass is critical for generating and sustaining dendritic arbors, and disruption of mitochondrial distribution in mature neurons is associated with neurodegeneration. PMID- 27705786 TI - Acetylation Is Crucial for p53-Mediated Ferroptosis and Tumor Suppression. AB - Although previous studies indicate that loss of p53-mediated cell cycle arrest, apoptosis, and senescence does not completely abrogate its tumor suppression function, it is unclear how the remaining activities of p53 are regulated. Here, we have identified an acetylation site at lysine K98 in mouse p53 (or K101 for human p53). Whereas the loss of K98 acetylation (p53K98R) alone has very modest effects on p53-mediated transactivation, simultaneous mutations at all four acetylation sites (p534KR: K98R+ 3KR[K117R+K161R+K162R]) completely abolish its ability to regulate metabolic targets, such as TIGAR and SLC7A11. Notably, in contrast to p533KR, p534KR is severely defective in suppressing tumor growth in mouse xenograft models. Moreover, p534KR is still capable of inducing the p53 Mdm2 feedback loop, but p53-dependent ferroptotic responses are markedly abrogated. Together, these data indicate the critical role of p53 acetylation in ferroptotic responses and its remaining tumor suppression activity. PMID- 27705792 TI - Deciphering the Innate Lymphoid Cell Transcriptional Program. AB - Innate lymphoid cells (ILCs) are enriched at mucosal surfaces, where they provide immune surveillance. All ILC subsets develop from a common progenitor that gives rise to pre-committed progenitors for each of the ILC lineages. Currently, the temporal control of gene expression that guides the emergence of these progenitors is poorly understood. We used global transcriptional mapping to analyze gene expression in different ILC progenitors. We identified PD-1 to be specifically expressed in PLZF+ ILCp and revealed that the timing and order of expression of the transcription factors NFIL3, ID2, and TCF-1 was critical. Importantly, induction of ILC lineage commitment required only transient expression of NFIL3 prior to ID2 and TCF-1 expression. These findings highlight the importance of the temporal program that permits commitment of progenitors to the ILC lineage, and they expand our understanding of the core transcriptional program by identifying potential regulators of ILC development. PMID- 27705787 TI - Non-canonical PI3K-Cdc42-Pak-Mek-Erk Signaling Promotes Immune-Complex-Induced Apoptosis in Human Neutrophils. AB - Neutrophils are peripheral blood leukocytes that represent the first line of immune cell defense against bacterial and fungal infections but are also crucial players in the generation of the inflammatory response. Many neutrophil cell surface receptors regulate important cellular processes via activation of agonist activated PI3Ks. We show here that activation of human neutrophils with insoluble immune complexes drives a previously uncharacterized, PI3K-dependent, non canonical, pro-apoptotic signaling pathway, FcgammaR-PI3Kbeta/delta-Cdc42-Pak-Mek Erk. This is a rare demonstration of Ras/Raf-independent activation of Erk and of PI3K-mediated activation of Cdc42. In addition, comparative analysis of immune complex- and fMLF-induced signaling uncovers key differences in pathways used by human and murine neutrophils. The non-canonical pathway we identify in this study may be important for the resolution of inflammation in chronic inflammatory diseases that rely on immune-complex-driven neutrophil activation. PMID- 27705793 TI - A Thymic Epithelial Stem Cell Pool Persists throughout Ontogeny and Is Modulated by TGF-beta. AB - Adult tissue-specific stem cells (SCs) mediate tissue homeostasis and regeneration and can give rise to all lineages in the corresponding tissue, similar to the early progenitors that generate organs in the first place. However, the developmental origins of adult SCs are largely unknown. We recently identified thymosphere-forming stem cells (TSFCs) in the adult mouse thymus, which display genuine stemness features and can generate the two major thymic epithelial cell lineages. Here, we show that embryonic TSFCs possess stemness features but differ from adult TSFCs in surface marker profile. Our findings support the model of a continuous thymic SC lineage that is maintained throughout ontogeny. TGF-beta signaling differentially affects embryonic versus adult thymosphere formation, suggesting that thymic epithelial SC potency depends on both developmental stage and environmental signals. Collectively, our findings suggest that embryonic TSFCs contribute to an adult SC pool and that TSFC plasticity is controlled by TGF-beta signaling. PMID- 27705791 TI - Association of a Network of Interferon-Stimulated Genes with a Locus Encoding a Negative Regulator of Non-conventional IKK Kinases and IFNB1. AB - Functional genomic analysis of gene expression in mice allowed us to identify a quantitative trait locus (QTL) linked in trans to the expression of 190 gene transcripts and in cis to the expression of only two genes, one of which was Ypel5. Most of the trans-expression QTL genes were interferon-stimulated genes (ISGs), and their expression in mouse macrophage cell lines was stimulated in an IFNB1-dependent manner by Ypel5 silencing. In human HEK293T cells, YPEL5 silencing enhanced the induction of IFNB1 by pattern recognition receptors and phosphorylation of TBK1/IKBKE kinases, whereas co-immunoprecipitation experiments revealed that YPEL5 interacted physically with IKBKE. We thus found that the Ypel5 gene (contained in a locus linked to a network of ISGs in mice) is a negative regulator of IFNB1 production and innate immune responses that interacts functionally and physically with TBK1/IKBKE kinases. PMID- 27705788 TI - Self-Antigen-Driven Thymic B Cell Class Switching Promotes T Cell Central Tolerance. AB - B cells are unique antigen-presenting cells because their antigen presentation machinery is closely tied to the B cell receptor. Autoreactive thymic B cells can efficiently present cognate self-antigens to mediate CD4+ T cell-negative selection. However, the nature of thymocyte-thymic B cell interaction and how this interaction affects the selection of thymic B cell repertoire and, in turn, the T cell repertoire are not well understood. Here we demonstrate that a large percentage of thymic B cells have undergone class switching intrathymically. Thymic B cell class switching requires cognate interaction with specific T cells. Class-switched thymic B cells have a distinct repertoire compared with unswitched thymic B cells or splenic B cells. Particularly, autoreactive B cell specificities preferentially expand in the thymus by undergoing class switching, and these enriched, class-switched autoreactive thymic B cells play an important role in CD4 T cell tolerance. PMID- 27705785 TI - DIGIT Is a Conserved Long Noncoding RNA that Regulates GSC Expression to Control Definitive Endoderm Differentiation of Embryonic Stem Cells. AB - Long noncoding RNAs (lncRNAs) exhibit diverse functions, including regulation of development. Here, we combine genome-wide mapping of SMAD3 occupancy with expression analysis to identify lncRNAs induced by activin signaling during endoderm differentiation of human embryonic stem cells (hESCs). We find that DIGIT is divergent to Goosecoid (GSC) and expressed during endoderm differentiation. Deletion of the SMAD3-occupied enhancer proximal to DIGIT inhibits DIGIT and GSC expression and definitive endoderm differentiation. Disruption of the gene encoding DIGIT and depletion of the DIGIT transcript reveal that DIGIT is required for definitive endoderm differentiation. In addition, we identify the mouse ortholog of DIGIT and show that it is expressed during development and promotes definitive endoderm differentiation of mouse ESCs. DIGIT regulates GSC in trans, and activation of endogenous GSC expression is sufficient to rescue definitive endoderm differentiation in DIGIT-deficient hESCs. Our study defines DIGIT as a conserved noncoding developmental regulator of definitive endoderm. PMID- 27705798 TI - MyoD Regulates Skeletal Muscle Oxidative Metabolism Cooperatively with Alternative NF-kappaB. AB - MyoD is a key regulator of skeletal myogenesis that directs contractile protein synthesis, but whether this transcription factor also regulates skeletal muscle metabolism has not been explored. In a genome-wide ChIP-seq analysis of skeletal muscle cells, we unexpectedly observed that MyoD directly binds to numerous metabolic genes, including those associated with mitochondrial biogenesis, fatty acid oxidation, and the electron transport chain. Results in cultured cells and adult skeletal muscle confirmed that MyoD regulates oxidative metabolism through multiple transcriptional targets, including PGC-1beta, a master regulator of mitochondrial biogenesis. We find that PGC-1beta expression is cooperatively regulated by MyoD and the alternative NF-kappaB signaling pathway. Bioinformatics evidence suggests that this cooperativity between MyoD and NF-kappaB extends to other metabolic genes as well. Together, these data identify MyoD as a regulator of the metabolic capacity of mature skeletal muscle to ensure that sufficient energy is available to support muscle contraction. PMID- 27705795 TI - MyT1 Counteracts the Neural Progenitor Program to Promote Vertebrate Neurogenesis. AB - The generation of neurons from neural stem cells requires large-scale changes in gene expression that are controlled to a large extent by proneural transcription factors, such as Ascl1. While recent studies have characterized the differentiation genes activated by proneural factors, less is known on the mechanisms that suppress progenitor cell identity. Here, we show that Ascl1 induces the transcription factor MyT1 while promoting neuronal differentiation. We combined functional studies of MyT1 during neurogenesis with the characterization of its transcriptional program. MyT1 binding is associated with repression of gene transcription in neural progenitor cells. It promotes neuronal differentiation by counteracting the inhibitory activity of Notch signaling at multiple levels, targeting the Notch1 receptor and many of its downstream targets. These include regulators of the neural progenitor program, such as Hes1, Sox2, Id3, and Olig1. Thus, Ascl1 suppresses Notch signaling cell-autonomously via MyT1, coupling neuronal differentiation with repression of the progenitor fate. PMID- 27705789 TI - Type I Interferons Regulate Immune Responses in Humans with Blood-Stage Plasmodium falciparum Infection. AB - The development of immunoregulatory networks is important to prevent disease. However, these same networks allow pathogens to persist and reduce vaccine efficacy. Here, we identify type I interferons (IFNs) as important regulators in developing anti-parasitic immunity in healthy volunteers infected for the first time with Plasmodium falciparum. Type I IFNs suppressed innate immune cell function and parasitic-specific CD4+ T cell IFNgamma production, and they promoted the development of parasitic-specific IL-10-producing Th1 (Tr1) cells. Type I IFN-dependent, parasite-specific IL-10 production was also observed in P. falciparum malaria patients in the field following chemoprophylaxis. Parasite induced IL-10 suppressed inflammatory cytokine production, and IL-10 levels after drug treatment were positively associated with parasite burdens before anti parasitic drug administration. These findings have important implications for understanding the development of host immune responses following blood-stage P. falciparum infection, and they identify type I IFNs and related signaling pathways as potential targets for therapies or vaccine efficacy improvement. PMID- 27705794 TI - Developmental Vitamin D Availability Impacts Hematopoietic Stem Cell Production. AB - Vitamin D insufficiency is a worldwide epidemic affecting billions of individuals, including pregnant women and children. Despite its high incidence, the impact of active vitamin D3 (1,25(OH)D3) on embryonic development beyond osteo-regulation remains largely undefined. Here, we demonstrate that 1,25(OH)D3 availability modulates zebrafish hematopoietic stem and progenitor cell (HSPC) production. Loss of Cyp27b1-mediated biosynthesis or vitamin D receptor (VDR) function by gene knockdown resulted in significantly reduced runx1 expression and Flk1+cMyb+ HSPC numbers. Selective modulation in vivo and in vitro in zebrafish indicated that vitamin D3 acts directly on HSPCs, independent of calcium regulation, to increase proliferation. Notably, ex vivo treatment of human HSPCs with 1,25(OH)D3 also enhanced hematopoietic colony numbers, illustrating conservation across species. Finally, gene expression and epistasis analysis indicated that CXCL8(IL-8) was a functional target of vitamin D3-mediated HSPC regulation. Together, these findings highlight the relevance of developmental 1,25(OH)D3 availability for definitive hematopoiesis and suggest potential therapeutic utility in HSPC expansion. PMID- 27705797 TI - S6K1 Is Required for Increasing Skeletal Muscle Force during Hypertrophy. AB - Loss of skeletal muscle mass and force aggravates age-related sarcopenia and numerous pathologies, such as cancer and diabetes. The AKT-mTORC1 pathway plays a major role in stimulating adult muscle growth; however, the functional role of its downstream mediators in vivo is unknown. Here, we show that simultaneous inhibition of mTOR signaling to both S6K1 and 4E-BP1 is sufficient to reduce AKT induced muscle growth and render it insensitive to the mTORC1-inhibitor rapamycin. Surprisingly, lack of mTOR signaling to 4E-BP1 only, or deletion of S6K1 alone, is not sufficient to reduce muscle hypertrophy or alter its sensitivity to rapamycin. However, we report that, while not required for muscle growth, S6K1 is essential for maintaining muscle structure and force production. Hypertrophy in the absence of S6K1 is characterized by compromised ribosome biogenesis and the formation of p62-positive protein aggregates. These findings identify S6K1 as a crucial player for maintaining muscle function during hypertrophy. PMID- 27705796 TI - VEGF-A/Notch-Induced Podosomes Proteolyse Basement Membrane Collagen-IV during Retinal Sprouting Angiogenesis. AB - During angiogenic sprouting, endothelial tip cells emerge from existing vessels in a process that requires vascular basement membrane degradation. Here, we show that F-actin/cortactin/P-Src-based matrix-degrading microdomains called podosomes contribute to this step. In vitro, VEGF-A/Notch signaling regulates the formation of functional podosomes in endothelial cells. Using a retinal neovascularization model, we demonstrate that tip cells assemble podosomes during physiological angiogenesis in vivo. In the retina, podosomes are also part of an interconnected network that surrounds large microvessels and impinges on the underlying basement membrane. Consistently, collagen-IV is scarce in podosome areas. Moreover, Notch inhibition exacerbates podosome formation and collagen-IV loss. We propose that the localized proteolytic action of podosomes on basement membrane collagen-IV facilitates endothelial cell sprouting and anastomosis within the developing vasculature. The identification of podosomes as key components of the sprouting machinery provides another opportunity to target angiogenesis therapeutically. PMID- 27705800 TI - PAXX Is an Accessory c-NHEJ Factor that Associates with Ku70 and Has Overlapping Functions with XLF. AB - In mammalian cells, classical non-homologous end joining (c-NHEJ) is critical for DNA double-strand break repair induced by ionizing radiation and during V(D)J recombination in developing B and T lymphocytes. Recently, PAXX was identified as a c-NHEJ core component. We report here that PAXX-deficient cells exhibit a cellular phenotype uncharacteristic of a deficiency in c-NHEJ core components. PAXX-deficient cells display normal sensitivity to radiomimetic drugs, are proficient in transient V(D)J recombination assays, and do not shift toward higher micro-homology usage in plasmid repair assays. Although PAXX-deficient cells lack c-NHEJ phenotypes, PAXX forms a stable ternary complex with Ku bound to DNA. Formation of this complex involves an interaction with Ku70 and requires a bare DNA extension for stability. Moreover, the relatively weak Ku-dependent stimulation of LIG4/XRCC4 activity by PAXX is unmasked by XLF ablation. Thus, PAXX plays an accessory role during c-NHEJ that is largely overlapped by XLF's function. PMID- 27705799 TI - Nat1 Deficiency Is Associated with Mitochondrial Dysfunction and Exercise Intolerance in Mice. AB - We recently identified human N-acetyltransferase 2 (NAT2) as an insulin resistance (IR) gene. Here, we examine the cellular mechanism linking NAT2 to IR and find that Nat1 (mouse ortholog of NAT2) is co-regulated with key mitochondrial genes. RNAi-mediated silencing of Nat1 led to mitochondrial dysfunction characterized by increased intracellular reactive oxygen species and mitochondrial fragmentation as well as decreased mitochondrial membrane potential, biogenesis, mass, cellular respiration, and ATP generation. These effects were consistent in 3T3-L1 adipocytes, C2C12 myoblasts, and in tissues from Nat1-deficient mice, including white adipose tissue, heart, and skeletal muscle. Nat1-deficient mice had changes in plasma metabolites and lipids consistent with a decreased ability to utilize fats for energy and a decrease in basal metabolic rate and exercise capacity without altered thermogenesis. Collectively, our results suggest that Nat1 deficiency results in mitochondrial dysfunction, which may constitute a mechanistic link between this gene and IR. PMID- 27705790 TI - HIV Triggers a cGAS-Dependent, Vpu- and Vpr-Regulated Type I Interferon Response in CD4+ T Cells. AB - Several pattern-recognition receptors sense HIV-1 replication products and induce type I interferon (IFN-I) production under specific experimental conditions. However, it is thought that viral sensing and IFN induction are virtually absent in the main target cells of HIV-1 in vivo. Here, we show that activated CD4+ T cells sense HIV-1 infection through the cytosolic DNA sensor cGAS and mount a bioactive IFN-I response. Efficient induction of IFN-I by HIV-1 infection requires proviral integration and is regulated by newly expressed viral accessory proteins: Vpr potentiates, while Vpu suppresses cGAS-dependent IFN-I induction. Furthermore, Vpr also amplifies innate sensing of HIV-1 infection in Vpx-treated dendritic cells. Our results identify cGAS as mediator of an IFN-I response to HIV-1 infection in CD4+ T cells and demonstrate that this response is modulated by the viral accessory proteins Vpr and Vpu. Thus, viral innate immune evasion is incomplete in the main target cells of HIV-1. PMID- 27705801 TI - Robust Replication Control Is Generated by Temporal Gaps between Licensing and Firing Phases and Depends on Degradation of Firing Factor Sld2. AB - Temporal separation of DNA replication initiation into licensing and firing phases ensures the precise duplication of the genome during each cell cycle. Cyclin-dependent kinase (CDK) is known to generate this separation by activating firing factors and at the same time inhibiting licensing factors but may not be sufficient to ensure robust separation at transitions between both phases. Here, we show that a temporal gap separates the inactivation of firing factors from the re-activation of licensing factors during mitosis in budding yeast. We find that gap size critically depends on phosphorylation-dependent degradation of the firing factor Sld2 mediated by CDK, DDK, Mck1, and Cdc5 kinases and the ubiquitin ligases Dma1/2. Stable mutants of Sld2 minimize the gap and cause increased genome instability in an origin-dependent manner when combined with deregulation of other replication regulators or checkpoint mechanisms. Robust separation of licensing and firing phases therefore appears indispensable to safeguard genome stability.

PMID- 27705809 TI - The effect of lead contamination on bioturbation by Lumbriculus variegatus in a freshwater microcosm. AB - The present study investigated the effect of lead (Pb) on bioturbation by the oligochaete worm Lumbriculus variegatus, using freshwater microcosms. The experiment used lead at "0", 140, 700, and 3500 MUg/g in sediment, and used two different laboratory populations of L. variegatus. A molecular genetic analysis and bioassays were conducted to determine if the two populations differed genetically and whether they differed in Pb-sensitivity. The bioturbation of L. variegatus was estimated using luminophores placed at the sediment-water interface at the beginning of the experiment. After the 14 d experiment the luminophore profiles in sediment were used to estimate the biodiffusion and bioadvection coefficients, using the diffusion-advection model. The results showed that the biodiffusion and bioadvection coefficients were generally negatively related to the Pb concentrations in the sediment. Lead at 700 and 3500 MUg/g reduced both coefficients, while Pb at 140 MUg/g did not. Luminophore profiles in the "0" and 140 MUg/g treatments were indicative of a non-local transport, while a diffusive transport was observed at the higher Pb levels. The two laboratory populations of L. variegatus used in the experiment differed in their sensitivity to Pb when mortality was used as the endpoint, but they did not differ in sediment bioturbation or the Pb-sensitivity of this process. Moreover, the genetic analysis did not detect any genetic differences between the populations. This study demonstrated that elevated levels of Pb can impact ecosystem functioning by decreasing the bioturbation activity of benthic organisms such as L. variegatus. PMID- 27705803 TI - A High-Density Map for Navigating the Human Polycomb Complexome. AB - Polycomb group (PcG) proteins are major determinants of gene silencing and epigenetic memory in higher eukaryotes. Here, we systematically mapped the human PcG complexome using a robust affinity purification mass spectrometry approach. Our high-density protein interaction network uncovered a diverse range of PcG complexes. Moreover, our analysis identified PcG interactors linking them to the PcG system, thus providing insight into the molecular function of PcG complexes and mechanisms of recruitment to target genes. We identified two human PRC2 complexes and two PR-DUB deubiquitination complexes, which contain the O-linked N acetylglucosamine transferase OGT1 and several transcription factors. Finally, genome-wide profiling of PR-DUB components indicated that the human PR-DUB and PRC1 complexes bind distinct sets of target genes, suggesting differential impact on cellular processes in mammals. PMID- 27705808 TI - Oxidative stress intensity-related effects of cadmium (Cd) and paraquat (PQ) on UV-damaged-DNA binding and excision repair activities in zebrafish (Danio rerio) embryos. AB - Our earlier studies showed the inhibitory effects of cadmium (Cd) and paraquat (PQ) on the gene expression of DNA mismatch recognition proteins in zebrafish (Danio rerio) embryos. This study explored the effects of Cd and PQ on nucleotide excision repair (NER) capacity in zebrafish embryos. Exposure of embryos at 1 h post fertilization (hpf) to 3-5 MUM Cd or 30-100 MUM PQ for 9 h induced a 2-3 fold increase of oxidative stress, while a 6.5-fold increase of oxidative stress was induced by 200 MUM PQ. Real-time RT-PCR detected a down-regulated xeroderma pigmentosum C (XPC) and an up-regulated UV-DDB2 gene expression in mildly stressed embryos, whereas 8-oxoguanine DNA glycosylase (OGG1) gene expression increased with PQ exposure levels. NER of UV-damaged DNA was enhanced in weakly oxidant-stressed embryos as shown by a transcription-based DNA repair assay, yet repair activities of both UV and cisplatin-damaged DNA were inhibited in embryos exposed to 200 MUM PQ. Band shift assay showed a suppression of cyclobutane pyrimidine dimer (CPD) binding activity in all stressed embryos. In contrast, (6 4) photoproduct (6-4PP) recognition activity was weakly stimulated except in embryos exposed to 200 MUM PQ, revealing a link of NER capacity to 6-4PP binding. Our results showed that Cd and PQ imposed similar inducing effects on UV-DDB2 gene expression, NER of UV-damaged DNA and 6-4PP binding activity in zebrafish embryo under low levels of oxidative stress and NER capacity could be inhibited if the intensity of oxidative stress increased to a critical level. PMID- 27705807 TI - A passive sampling method for assessing the occurrence and risk of organophosphate flame retardants in aquatic environments. AB - A modified polar organic chemical integrative sampler (m-POCIS) was used to determine the occurrence of and risk posed by organophosphate flame retardants (OPFRs) in the Yangtze River in Nanjing. Laboratory calibrations were performed to determine sampling rates (Rs) in different situations. Rs values increased with the flow rate, but the effect of dissolved organic matter (DOM) on Rs was relatively small. The validation of Rs in the m-POCIS for 15 days at the Yangtze River in 2015 showed that the Rs values for most of the test compounds are considerably larger than those obtained in the laboratory. The aqueous concentrations of OPFRs were estimated by using Rs values obtained in the field. OPFRs were widely distributed in the Yangtze River, with total concentrations as determined by the m-POCIS ranging from 44.95 ng/L to 118.38 ng/L. These suggest their widespread use and persistence in the river. This study also provided a protocol for the assessment of risk posed by OPFRs. It showed that tripentyl phosphate (TPeP) could pose medium risk to daphnia in the Yangtze River. PMID- 27705810 TI - Organic complexation of copper in throughfall and open field bulk deposition: Influence of the tree canopy of Mediterranean forest ecosystems. AB - The complexing capacity for Cu ions (LT) and the apparent stability constant values (logKapp) were measured in throughfall (TF) and open field bulk deposition (BD), at two Mediterranean forest ecosystems of western Greece. LT was measured for the first time in the TF of natural forests. Concentrations of LT were three to-four-fold higher in TF (mean +/- st.dev: 2014 +/- 769 nM for Varetada and 1565 +/- 595 nM for Karpenissi) compared to those in BD (531 +/- 517 nM and 468 +/- 321 nM, respectively). In all TF and BD samples, LT concentrations were significantly higher than the corresponding total Cu concentrations, indicating that Cu was fully complexed. The LT/TOC ratios in TF were found comparable between the two study sites (235 +/- 149 nM mg-1 C for Varetada and 256 +/- 233 nM mg-1 C for Karpenissi) and with those of BD (226 +/- 257 and 163 +/- 163 nM mg 1 C, respectively). The determined mean logKapp values were almost identical in TF (6.8 +/- 0.7 at Varetada; 6.8 +/- 0.6 at Karpenissi) and BD (6.5 +/- 0.6 at Varetada; 6.8 +/- 0.3 at Karpenissi), pointing to the fact that regardless of the enrichment of TF in ligands (LT(TF) > LT(BD)) the type of binding sites remain the same. The logKapp values which were obtained herewith are similar to those obtained for humic-like substances (HULIS), indicating them as the most widespread type of ligands in BD and TF.

AB - Type IVa pili (T4aP) function as bacterial virulence factors. T4aP pass through the outer membranes of Gram-negative bacteria via homo-oligomeric secretins. We present a 7.4 A cryoelectron microscopy structure of the Pseudomonas aeruginosa PilQ secretin. Peripheral and internal features show that the secretin is composed of 14 subunits with C7 symmetry. The channel is a ribbed cylinder with central peripheral spokes and a central gate closed on the periplasmic side. The structure suggests that during pilus extrusion, the central gate is displaced to the interior walls and that no additional conformational changes are required, as the internal diameter can accommodate the pilus. The N1 domain was resolved, while the N0 and the N-terminal beta-domains proposed to bind peptidoglycan were absent in class average images and the final 3D map, indicating a high flexibility. These data provide the highest-resolution structure to date of a T4aP secretin. PMID- 27705804 TI - Insights into the Pathogenesis of Anaplastic Large-Cell Lymphoma through Genome wide DNA Methylation Profiling. AB - Aberrant DNA methylation patterns in malignant cells allow insight into tumor evolution and development and can be used for disease classification. Here, we describe the genome-wide DNA methylation signatures of NPM-ALK-positive (ALK+) and NPM-ALK-negative (ALK-) anaplastic large-cell lymphoma (ALCL). We find that ALK+ and ALK- ALCL share common DNA methylation changes for genes involved in T cell differentiation and immune response, including TCR and CTLA-4, without an ALK-specific impact on tumor DNA methylation in gene promoters. Furthermore, we uncover a close relationship between global ALCL DNA methylation patterns and those in distinct thymic developmental stages and observe tumor-specific DNA hypomethylation in regulatory regions that are enriched for conserved transcription factor binding motifs such as AP1. Our results indicate similarity between ALCL tumor cells and thymic T cell subsets and a direct relationship between ALCL oncogenic signaling and DNA methylation through transcription factor induction and occupancy. PMID- 27705805 TI - Transcriptional Profiling Reveals a Common Metabolic Program in High-Risk Human Neuroblastoma and Mouse Neuroblastoma Sphere-Forming Cells. AB - High-risk neuroblastoma remains one of the deadliest childhood cancers. Identification of metabolic pathways that drive or maintain high-risk neuroblastoma may open new avenues of therapeutic interventions. Here, we report the isolation and propagation of neuroblastoma sphere-forming cells with self renewal and differentiation potential from tumors of the TH-MYCN mouse, an animal model of high-risk neuroblastoma with MYCN amplification. Transcriptional profiling reveals that mouse neuroblastoma sphere-forming cells acquire a metabolic program characterized by transcriptional activation of the cholesterol and serine-glycine synthesis pathways, primarily as a result of increased expression of sterol regulatory element binding factors and Atf4, respectively. This metabolic reprogramming is recapitulated in high-risk human neuroblastomas and is prognostic for poor clinical outcome. Genetic and pharmacological inhibition of the metabolic program markedly decreases the growth and tumorigenicity of both mouse neuroblastoma sphere-forming cells and human neuroblastoma cell lines. These findings suggest a therapeutic strategy for targeting the metabolic program of high-risk neuroblastoma. PMID- 27705816 TI - Beyond the survival and death of the deltamethrin-threatened pollen beetle Meligethes aeneus: An in-depth proteomic study employing a transcriptome database. AB - : Insecticide resistance is an increasingly global problem that hampers pest control. We sought the mechanism responsible for survival following pyrethroid treatment and the factors connected to paralysis/death of the pollen beetle Meligethes aeneus through a proteome-level analysis using nanoLC coupled with Orbitrap FusionTM TribridTM mass spectrometry. A tolerant field population of beetles was treated with deltamethrin, and the ensuing proteome changes were observed in the survivors (resistant), dead (paralyzed) and control-treated beetles. The protein database consisted of the translated transcriptome, and the resulting changes were manually annotated via BLASTP. We identified a number of high-abundance changes in which there were several dominant proteins, e.g., the electron carrier cytochrome b5, ribosomal proteins 60S RPL28, 40S RPS23 and RPS26, eIF4E-transporter, anoxia up-regulated protein, 2 isoforms of vitellogenin and pathogenesis-related protein 5. Deltamethrin detoxification was influenced by different cytochromes P450, which were likely boosted by increased cytochrome b5, but glutathione-S-transferase epsilon and UDP-glucuronosyltransferases also contributed. Moreover, we observed changes in proteins related to RNA interference, RNA binding and epigenetic modifications. The high changes in ribosomal proteins and associated factors suggest specific control of translation. Overall, we showed modulation of expression processes by epigenetic markers, alternative splicing and translation. Future functional studies will benefit. BIOLOGICAL SIGNIFICANCE: Insects develop pesticide resistance, which has become one of the key issues in plant protection. This growing resistance increases the demand for pesticide applications and the development of new substances. Knowledge in the field regarding the resistance mechanism and its responses to pesticide treatment provides us the opportunity to propose a solution for this issue. Although the pollen beetle Meligethes aeneus was effectively controlled with pyrethroids for many years, there have been reports of increasing resistance. We show protein changes including production of isoforms in response to deltamethrin at the protein level. These results illustrate the insect's survival state as a resistant beetle and in its paralyzed state (evaluated as dead) relative to resistant individuals. PMID- 27705818 TI - Treatment of groundwater containing Mn(II), Fe(II), As(III) and Sb(III) by bioaugmented quartz-sand filters. AB - High concentrations of iron (Fe(II)) and manganese (Mn(II)) often occur simultaneously in groundwater. Previously, we demonstrated that Fe(II) and Mn(II) could be oxidized to biogenic Fe-Mn oxides (BFMO) via aeration and microbial oxidation, and the formed BFMO could further oxidize and adsorb other pollutants (e.g., arsenic (As(III)) and antimony (Sb(III))). To apply this finding to groundwater remediation, we established four quartz-sand columns for treating groundwater containing Fe(II), Mn(II), As(III), and Sb(III). A Mn-oxidizing bacterium (Pseudomonas sp. QJX-1) was inoculated into two parallel bioaugmented columns. Long-term treatment (120 d) showed that bioaugmentation accelerated the formation of Fe-Mn oxides, resulting in an increase in As and Sb removal. The bioaugmented columns also exhibited higher overall treatment effect and anti shock load capacity than that of the non-bioaugmented columns. To clarify the causal relationship between the microbial community and treatment effect, we compared the biomass of active bacteria (reverse-transcribed real-time PCR), bacterial community composition (Miseq 16S rRNA sequencing) and community function (metagenomic sequencing) between the bioaugmented and non-bioaugmented columns. Results indicated that the QJX1 strain grew steadily and attached onto the filter material surface in the bioaugmented columns. In general, the inoculated strain did not significantly alter the composition of the indigenous bacterial community, but did improve the relative abundances of xenobiotic metabolism genes and Mn oxidation gene. Thus, bioaugmentation intensified microbial degradation/utilization for the direct removal of pollutants and increased the formation of Fe-Mn oxides for the indirect removal of pollutants. Our study provides an alternative method for the treatment of groundwater containing high Fe(II), Mn(II) and As/Sb. PMID- 27705802 TI - Cytosolic Accumulation of L-Proline Disrupts GABA-Ergic Transmission through GAD Blockade. AB - Proline dehydrogenase (PRODH), which degrades L-proline, resides within the schizophrenia-linked 22q11.2 deletion suggesting a role in disease. Supporting this, elevated L-proline levels have been shown to increase risk for psychotic disorders. Despite the strength of data linking PRODH and L-proline to neuropsychiatric diseases, targets of disease-relevant concentrations of L proline have not been convincingly described. Here, we show that Prodh-deficient mice with elevated CNS L-proline display specific deficits in high-frequency GABA ergic transmission and gamma-band oscillations. We find that L-proline is a GABA mimetic and can act at multiple GABA-ergic targets. However, at disease-relevant concentrations, GABA-mimesis is limited to competitive blockade of glutamate decarboxylase leading to reduced GABA production. Significantly, deficits in GABA ergic transmission are reversed by enhancing net GABA production with the clinically relevant compound vigabatrin. These findings indicate that accumulation of a neuroactive metabolite can lead to molecular and synaptic dysfunction and help to understand mechanisms underlying neuropsychiatric disease.

PMID- 27705817 TI - Peptidomics of the zebrafish Danio rerio: In search for neuropeptides. AB - : (Neuro)peptides are small messenger molecules that are derived from larger, inactive precursor proteins by the highly controlled action of processing enzymes. These biologically active peptides can be found in all metazoan species where they orchestrate a wide variety of physiological processes. Obviously, detailed knowledge on the actual peptide sequences, including the potential existence of truncated versions or presence of post-translation modifications, is of high importance when studying their function. A peptidomics approach therefore aims to identify and characterize the endogenously present peptide complement of a defined tissue or organism using liquid chromatography and mass spectrometry. While the zebrafish Danio rerio is considered as an important aquatic model for medical research, neuroscience, development and ecotoxicology, very little is known about their peptidergic signaling cascades. We therefore set out to biochemically characterize endogenously present (neuro)peptides from the zebrafish brain. This peptidomics setup yielded >60 different peptides in addition to various truncated versions. SIGNIFICANCE: Though the zebrafish is a well-established model organism to study vertebrate biology and gene functions in either a medical or (eco)toxicological context, very little knowledge about neuropeptidergic signaling cascades is available. We therefore set out to characterize endogenously present peptides from the zebrafish brain using a peptidomics setup yielding a total number of 105 peptide identifications. To our knowledge, it is the first attempt to biochemically isolate and characterize neuropeptides from a fish species in a high-throughput manner. This archive of identified endogenous peptides is likely to aid further functional elucidation of defined neuropeptidergic signaling systems (e.g. characterization of cognate G protein coupled receptors). Furthermore, our methodology allows studying the changes in peptide expression in response to changes in the organism or the environment using differential peptidomics. PMID- 27705819 TI - Revisiting the association between childhood trauma and psychosis in bipolar disorder: A quasi-dimensional path-analysis. AB - BACKGROUND: Childhood trauma has been associated with a more severe clinical expression of bipolar disorder (BD). However, the results that specifically associated traumatic events and psychotic features in BD have been inconsistent, possibly due to the low resolution of the phenotypes being used. METHODS: 270 normothymic patients with BD completed the Childhood Trauma Questionnaire (CTQ) and the Peters Delusion Inventory (PDI) that assessed 21 delusional beliefs. Patients were characterized for the lifetime presence of psychotic features during episodes and cannabis misuse in accordance with DSM-IV. We performed a series of path analyses to investigate the links from three types of childhood abuse (physical, sexual and emotional) directly to delusional beliefs and psychotic features, and indirectly through cannabis misuse. RESULTS: A first path analysis showed no link between any of the childhood abuse types and psychotic features when only a categorical definition of psychosis was used. When incorporating the quasi-dimensional measure of delusional beliefs in a second path analysis, we found that emotional and physical abuse and cannabis misuse were each directly associated with PDI score. PDI score and psychotic features were strongly correlated. Childhood abuse did not operate through cannabis misuse to increase delusional beliefs. Including type of BD in the model did not alter the results. CONCLUSION: Emotional and physical abuse, but also cannabis misuse, increased delusional beliefs in patients with BD. Using a quasi-dimensional measure of psychotic symptoms in BD provided higher resolution of the psychosis phenotype and helped reconcile ambiguous findings from previous studies.

AB - Lucrecia city, known to harbor a high cancer rate, is located in a semiarid region characterized by the presence of mineral reservoirs, facing a high exposure to metal and natural radioactivity. The present study aimed to assess the environmental scenario at a semiarid region located in Northeastern Brazil. Metal concentration, alpha and beta radiation, and cyanobacteria content in tap water along with indoor radon and gamma emitters (U, K and Th) concentrations were measured. In addition, mutagenic and nuclear instability effects were assessed using buccal micronucleus cytome assay. The study included five samplings corresponding to a period between 2007 and 2009. Drinking water from Lucrecia city presented levels of Mn, Ni and Cr along with cyanobacteria in concentrations one to four times higher than regulatory guidelines considered. Furthermore, high levels of all the tested radionuclides were found. A high percentage of the houses included in this study presented indoor radon concentrations over 100 Bq m-3. The mean annual effective dose from Lucrecia houses was six times higher than observed in a control region. The levels of exposure in most of the Lucrecia houses were classified as middle to high. A significant mutagenic effect, represented as an increase of micronuclei (MN) frequency and nuclear abnormalities as nuclear buds (NB), binucleated cells (BN), and pyknotic cells (PYC) were found. The results obtained highlight the role of high background radioactivity on the observed mutagenic effect and could help to explain the exacerbated cancer rate reported in this locality. PMID- 27705821 TI - Corrigendum to "Influence of Histidine-198 of the D1 subunit on the properties of the primary electron donor, P680, of photosystem II in Thermosynechococcus elongatus". AB - Two mutants, D1-H198Q and D1-H198A, have been previously constructed in Thermosynechococcus elongatus with the aim at modifying the redox potential of the P680*+/P680 couple by changing the axial ligand of PD1, one the two chlorophylls of the Photosystem II primary electron donor [Sugiura et al., Biochim. Biophys. Acta 1777 (2008) 331-342]. However, after the publication of this work it was pointed out to us by Dr. Eberhard Schlodder (Technische Universitat Berlin) that in both mutants the pheophytin band shift which is observed upon the reduction of QA was centered at 544nm instead of 547nm, clearly showing that the D1 protein corresponded to PsbA1 whereas the mutants were supposedly constructed in the psbA3 gene so that the conclusions in our previous paper were wrong. O2 evolving mutants have been therefore reconstructed and their analyze shows that they are now correct mutants which are suitable for further studies. Indeed, the D1-H198Q mutation downshifted by ~3nm the P680*+/P680 difference absorption spectrum in the Soret region and increased the redox potential of the P680*+/P680 couple and the D1-H198A mutation decreased the redox potential of the P680*+/P680 couple all these effects being comparable to those which were observed in Synechocystis sp. PCC 6803 [Diner et al., Biochemistry 40 (2001) 9265-9281 and Merry et al. Biochemistry 37 (1998) 17,439-17,447]. We apologize for having presented wrong data and wrong conclusions in our earlier publication. PMID- 27705822 TI - Geochemical investigation of the galvanic effects during oxidation of pyrite and base-metals sulfides. AB - Predicting the water quality at mine sites is of significant importance for developing mines with respect for the environment. Acid mine drainage (AMD) occurs when sulfides are in contact with oxygen and water, and several parameters and mechanisms influence final drainage quality. Galvanic interactions influence the reactivity of sulfide minerals, which act as semi-conductors. These galvanic interactions have been insufficiently studied in the context of AMD generation. In this study, the influence of pyrite on the reactivity of sphalerite and chalcopyrite was investigated. Five blends, comprised of free grains of quartz/pyrite, quartz/chalcopyrite, quartz/sphalerite, quartz/pyrite/chalcopyrite, and quartz/pyrite/sphalerite, were subjected to geochemical testing. Five weathering cells were monitored over a 200-day period during which they were leached twice weekly. Leachates were analyzed for pH, Eh, electrical conductivity, and sulfate and metal concentrations. The results of these analyses showed that galvanic interactions occurred between free sulfide grains. Pyrite was galvanically protected over the full testing period in the quartz/pyrite/chalcopyrite blend, and partially protected in the quartz/pyrite/sphalerite blend. Moreover, the release of Cu from chalcopyrite and Zn, Mn, and Cd from sphalerite was accelerated in the presence of pyrite. This work provides a better understanding of the influence of pyrite on chalcopyrite and sphalerite reactivity by highlighting the galvanic effects. In the future, to improve the reliability of AMD prediction tests, galvanic interactions should be considered in both the prediction of the acid generation potential and the estimation of metal and metalloid release rates. PMID- 27705823 TI - Nontargeted detection and identification of (aromatic) amines in environmental samples based on diagnostic derivatization and LC-high resolution mass spectrometry. AB - The presence of aromatic amines in the environment has been in the focus of research, as many of these compounds are known or suspected mutagens and carcinogens. To facilitate the detection of aromatic amines in complex environmental samples by LC-high resolution mass spectrometry, an on-line-post column and a pre-column derivatization method to label (in an ideal case) all aromatic amines was evaluated by applying different derivatization reagents. 4 Fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F) was found to be the most promising labeling reagent due to its high reactivity with both primary and secondary amines and its low signal in positive mode electrospray ionization (ESI+). Post column on-line derivatization did not result in sufficient signal intensities of derivatives. With pre-column derivatization most of the selected aromatic amines resulted in a derivative that shows common fragments of diagnostic value. The selectivity of NBD-F was studied in depth with a data set of 220 compounds with different functional groups showing that also aliphatic amines and some thiols yield a derivative. The developed method was successfully applied to wastewater effluent samples and several derivatives were confirmed by diagnostic neutral losses. PMID- 27705824 TI - Use of a chemometric tool to establish the regional background and assess trace metal enrichment at Baixada Santista - southeastern Brazil. AB - The trace metals in sediments consist of two components, anthropogenic and lithogenic or natural, which can cause misinterpretations for what actually exists in sediments. Normally, to investigate trace metal background levels, indices are applied in order to normalize the values and reduce natural variability, but it is well known that using the average shale or crust content is not the best choice and vertical sediment profiles are not always available. The purpose of this study is to use a prediction interval to assess metal enrichment without a reference level and to assess a regional background level using the same tool. The levels of eight elements were submitted to a partial digestion technique and analyzed by ICP-OES. The enrichment factor results suggested that using background values from the prediction interval and using values from vertical sediment profiles yield statistically similar results. Furthermore, the background equations present more realistic data than other methods because they consider the mud content of the samples. Thus, a prediction interval can be a useful tool to establish a regional background and assess trace metal enrichment. PMID- 27705825 TI - Application of mixed effects models for characterizing contaminated sites. AB - In a typical data collection process for the purpose of characterizing contaminated sites, boreholes are usually drilled in different locations based on a sampling plan; and consequently, multiple samples are collected from each borehole. As a result, it is quite plausible that a certain degree of dependency or similarity exists among observations nested within a borehole. However, when classical regression models are employed, such dependencies are often ignored, resulting in biased estimates. In site characterization studies, further complication arises due to the presence of left-censored observations, those falling below the detection limit of measuring instruments. To overcome the above issues, this paper employs a mixed effects model that allows accounting for the within-borehole data dependency while accommodating left-censored concentrations. The benefits of the adopted methodology are explored by analyzing concentration data obtained from characterization study of a brownfield site located in Montreal, Canada. This paper illustrates that the estimated within-borehole correlation can be used to determine the optimal number of boreholes as well as the sample size to be collected from each borehole. Such correlation is underestimated when censored values are not accommodated in the model but substituted with a constant prior to data analysis. In addition, the adopted methodology provides an accurate insight into the vertical extent of contamination that can result in different compliance decisions when compared with classical approach. PMID- 27705826 TI - Micro-distribution of arsenic species in tissues of hyperaccumulator Pteris vittata L. AB - Arsenic (As) contamination and its harmful consequences have gained increasing attention in research. Phytoextraction, which uses the As hyperaccumulator Pteris vittata L., is a well-established technology adopted in many countries. However, the hyperaccumulation mechanisms of this plant remain controversial. This study investigated the species and the micro-distribution of As species in three P. vittata L. ecotypes after exposure to arsenite (AsIII) and arsenate (AsV) for 7d. Arsenic-accumulating abilities and preferences to As species varied among different ecotypes. The reduction of AsV into AsIII, oxidation of AsIII into AsV, and chelation of AsIII with thiols were all observed in P. vittata. The reduction of As mainly occurred in the rhizoid, whereas oxidation and chelation mainly occurred in the aboveground parts. Correlation analyses showed that the As concentration in pinna was significantly correlated with the AsV percentage in paraxial and abaxial epidermis (positive), AsIII-GSH percentage in paraxial epidermis (positive), and AsIII percentage in paraxial and abaxial epidermis (negative). Results indicated that oxidation and chelation reactions contributed to the accumulation of As in P. vittata. PMID- 27705827 TI - Analysis of emerging contaminants in water and solid samples using high resolution mass spectrometry with a Q Exactive orbital ion trap and estrogenic activity with YES-assay. AB - Trace emerging contaminants (ECs) occur in both waste and surface waters that are rich in particulates that have been found to sorb several organic contaminants. An analytical method based on off-line solid-phase extraction (SPE) followed by liquid chromatography-mass spectrometry (LC-MS) analysis was developed for the detection and quantification of 31 ECs from surface water, wastewater, suspended particulate matter (SPM) as well as sediments. Lyophilized sediments and air dried SPM were subjected to ultrasonic extraction. Water samples and extracts were then concentrated and cleaned-up by off-line SPE. Quantification was realized using a Q Exactive mass spectrometer in both full scan (FS) and MS2 modes. These two modes were optimized and compared to determine which one was the most suitable for each matrix studied. Yeast estrogen screen assay (YES-assay) adapted from the direct measurement of estrogenic activity without sample extraction was tested on filtered wastewater samples. An endocrine disrupting effect was detected in all effluent samples analyzed with estradiol equivalent concentrations ranging from 4.4 to 720 ng eq E2 L-1 for the WWTP-1 and 6.5-42 ng eq E2 L-1 for the WWTP-2. The analytical methods were also applied on six samples of surface water, the corresponding SPM, the sediments and thirty-nine effluent samples from two wastewater treatment plants (WWTPs) sampled over a period of five months (February to June 2014). PMID- 27705829 TI - Effects of organic acids of different molecular size on phosphate removal by HZO 201 nanocomposite. AB - Various organic acids in wastewater effluent could significantly influence the performance of phosphate adsorbent. This study focused on the effects of organic acids of different-molecular-size on phosphate adsorption by a novel nanocomposite HZO-201. Three organic acids (gallic acid (GA), tannic acid (TA) and humic acid (HA)) with distinct molecular size (HA > TA > GA) were chosen for this purpose. Both isotherm and kinetic tests of phosphate adsorption were conducted in the single-phosphate and binary system, and a series of microscopic techniques (i.e., XPS, FT-IR and SEM-EDX) and N2 adsorption-desorption test were employed to explore the underlying mechanism. It was found that GA could greatly weaken phosphate adsorption capability of HZO-201 by directly competing for ammonium group on the nanocomposite, TA exhibited significant inhibition on phosphate adsorption rate mainly through pore constriction/blockage, while HA posed negligible impact on phosphate adsorption because of the size exclusion effect. It was also observed that although GA, TA and HA showed substantial influence on bulky HZO due to complexation, their impact on the nano-HZO loaded inside HZO-201 was little. The covalently bounded ammonium group and the networking pore structure of HZO-201 may play important roles in it. PMID- 27705828 TI - Occupational exposure to PCDDs, PCDFs, and DL-PCBs in metallurgical plants of the Brescia (Lombardy Region, northern Italy) area. AB - The concentration values of polychlorodibenzodioxins (PCDDs), polychlorodibenzofurans (PCDFs), and dioxin-like polychlorobiphenyls (DL-PCBs) in blood serum samples (pools) of metallurgical workers in the area of the city of Brescia (northern Italy) were statistically processed. As to workers' exposure characteristics, pools were divided into 34 professionally exposed (PE) and 11 non-professionally exposed (NPE). A further subdivision of PE pools was according to workplaces in which ferrous (N = 24) and non-ferrous (N = 10) materials were handled. To evaluate the aforesaid differences we applied the age-adjusted Generalized Linear Models. We identified significant (P <= 0.05) exposure models of the classification groups. The first subdivision was confirmed by the concentrations of 1,2,3,4,6,7,8-H7CDF, DL-PCB 105, and DL-PCB 189; the second was confirmed by the concentrations of PCDF TEQ97, PCDD + PCDF + DL-PCB (TEQTOT) TEQ97, 2,3,4,7,8-P5CDF, 1,2,3,6,7,8-H6CDD, 1,2,3,4,6,7,8-H7CDD, and PCB 189. Based on the literature, all mentioned congeners have been found in stack gas and fly ash samples of metallurgical plants: therefore, these indicators indicate the exposure to such work environments. Specifically, the concentrations measured in the workers' blood serum appear to depend on the type of material processed during work. PMID- 27705831 TI - Predicting acute contact toxicity of pesticides in honeybees (Apis mellifera) through a k-nearest neighbor model. AB - Ecological risk assessment of plant protection products (PPPs) requires an understanding of both the toxicity and the extent of exposure to assess risks for a range of taxa of ecological importance including target and non-target species. Non-target species such as honey bees (Apis mellifera), solitary bees and bumble bees are of utmost importance because of their vital ecological services as pollinators of wild plants and crops. To improve risk assessment of PPPs in bee species, computational models predicting the acute and chronic toxicity of a range of PPPs and contaminants can play a major role in providing structural and physico-chemical properties for the prioritisation of compounds of concern and future risk assessments. Over the last three decades, scientific advisory bodies and the research community have developed toxicological databases and quantitative structure-activity relationship (QSAR) models that are proving invaluable to predict toxicity using historical data and reduce animal testing. This paper describes the development and validation of a k-Nearest Neighbor (k NN) model using in-house software for the prediction of acute contact toxicity of pesticides on honey bees. Acute contact toxicity data were collected from different sources for 256 pesticides, which were divided into training and test sets. The k-NN models were validated with good prediction, with an accuracy of 70% for all compounds and of 65% for highly toxic compounds, suggesting that they might reliably predict the toxicity of structurally diverse pesticides and could be used to screen and prioritise new pesticides. PMID- 27705830 TI - Non-target analysis of household dust and laundry dryer lint using comprehensive two-dimensional liquid chromatography coupled with time-of-flight mass spectrometry. AB - Household dust and laundry dryer lint are important indoor environmental matrices that may have notable health effects on humans due to chronic exposure. However, due to the sample complexity the studies conducted on these sample matrices until now were almost exclusively on the basis of target analysis. In this study, comprehensive two-dimensional liquid chromatography coupled with time-of-flight mass spectrometry (LC * LC-ToF MS) was applied, to enable non-target analysis of household dust as well as laundry dryer lint for the first time. The higher peak capacity and good orthogonality of LC * LC, together with reduced ion suppression in the MS enabled rapid identification of environmental contaminants in these complex sample matrices. A number of environmental contaminants were tentatively identified based on their accurate masses and isotopic patterns, including plasticizers, flame retardants, pesticides, drug metabolites, etc. The identity of seven compounds: tris(2-butoxyethyl) phosphate, tris(2-chloropropyl) phosphate, n-benzyl butyl phthalate, dibutyl phthalate, tributyl phosphate, triethyl phosphate and N, N-diethyl-meta-toluamide was confirmed using two dimensional retention alignment and their concentrations in the samples were semi quantitatively determined. PMID- 27705832 TI - Physiological and biochemical effects of nickel on rainbow trout (Oncorhynchus mykiss) tissues: Assessment of nuclear factor kappa B activation, oxidative stress and histopathological changes. AB - We investigated changes in nuclear factor kappa B (NFkB) activity, antioxidant responses and histopathological effects in the liver, gill and kidney tissues of rainbow trout exposed to nickel chloride (Ni). Two different concentrations (1 mg/L and 2 mg/L) were administrated to fish for 21 days. Tissues were taken from all fish for NFkB activity, histopathological examination and determination of superoxide dismutase (SOD), catalase (CAT) enzyme activity and of lipid peroxidation (LPO), and glutathione (GSH) levels. The findings of this study indicated that Ni exposure led to a significant increase in LPO indicating peroxidative damage and antioxidant enzymes SOD and CAT activity in tissues (p < 0.05), but 2 mg/Ni concentration caused a significant decrease in CAT activity in kidney tissues (p < 0.05). One of mechanism in the antioxidant defense system seems to be GSH, which increased in gill and kidney tissues of fish exposed to Ni (p < 0.05). NFkB immunopositivity was detected in all tissues. Ni exposure caused lamellar thickening, cellular infiltration in gill tissues, hydropic degeneration of hepatocytes in liver tissues, hyalinous accumulation within the glomeruli and tubular degeneration in kidney tissues. Our results suggested that Ni toxicity may disturb the biochemical and physiological functions of fish by causing changes in NFkB activity and oxidative and histopathological damage in the tissues of rainbow trout. This study can provide useful information for understanding of Ni-induced toxicity.

AB - Oreochromis niloticus has been exposed to diclofenac (DCF), a nonsteroidal anti inflammatory drug prevalent in the aquatic environment, for 80 days post-hatch (dph). Concentrations ranged from environmentally relevant (0.1 MUg L-1 and 1 MUg L-1 DCF) up to 100-fold thereof. Population relevant endpoints (hatching, survival, growth) as well as gill histopathology were analyzed. On this level of examination only gills exhibited mild to moderate alterations. On the contrary, biomarkers associated with reproduction were affected due to DCF exposure, indicating the potential to affect sexual differentiation and gametogenesis by acting as an estrogenic endocrine disrupting compound (EDC) in tilapia. Vitellogenin (VTG) gene expression was significantly induced at 1 MUg L-1 DCF. In order to find an explanation, gene expression patterns of key enzymes of the biotransformation phases I, II, and III have been analyzed. It seems very likely that the detoxification metabolism is induced in a dose dependent manner at higher concentrations of DCF leading to the expression pattern of VTG mRNA. Our results suggest that DCF at environmentally relevant concentrations adversely affects O. niloticus gill histopathology and pituitary gene expression, and has the potential to act as an estrogenic EDC. The sensitivity of various endpoints, however, differs and therefore these endpoints should be linked. PMID- 27705834 TI - 1,3-Dinitrobenzene reductive degradation by alkaline ascorbic acid - Reaction mechanisms, degradation pathways and reagent optimization. AB - Nitro-aromatic compounds (NACs) such as 1,3-dinitrobenzene (1,3-DNB) contain the nitrogroup (-NO2), in which the N with a +III oxidation state accepts electrons. Water soluble ascorbic acid (AsA) at elevated pH produces electron transfer and governs the electron-donating pathway. The influence of the NaOH/AsA molar ratio on the degradation of 1,3-DNB was investigated. Using 0.21-2 M NaOH and 20-100 mM AsA, nearly complete 1,3-DNB removals (90-100%) were achieved within 0.5 h. On the basis of intermediates identified using GC/MS, the reduction pathways of 1,3 DNB can be categorized into step-by-step electron transfer, and condensation routes. A higher NaOH/AsA molar ratio would result in relatively higher AsA decomposition, promote the condensation route into the formation of azo- and azoxy-compounds, and ultimately reduce 1,3-DNB to 1,3-phenylenediamine. Contaminated soil flushing using 500 mM NaOH/100 mM AsA revealed that 1,3-DNB was completely degraded within 2 h. Based on these test results, the alkaline AsA treatment method is a potential remediation process for NACs contaminated soils.

AB - The Japanese cedar pollen allergen (Cry j1) and the mountain cedar pollen allergen (Jun a1) are glycosylated with plant complex type N-glycans bearing Lewis a epitope(s) (Galbeta1-3[Fucalpha1-4]GlcNAc-). The biological significance of Lewis a type plant N-glycans and their effects on the human immune system remain to be elucidated. Since a substantial amount of such plant specific N glycans are required to evaluate immunological activity, we have searched for good plant-glycan sources to characterize Lewis a epitope-containing plant N glycans. In this study, we have found that three water plants, Elodea nuttallii, Egeria densa, and Ceratophyllum demersum, produce glycoproteins bearing Lewis a units. Structural analysis of the N-glycans revealed that almost all glycoproteins expressed in these three water plants predominantly carry plant complex type N-glycans including the Lewis a type, suggesting that these water plants are good sources for preparation of Lewis a type plant N-glycans in substantial amounts. PMID- 27705836 TI - The risk factors for gestational diabetes mellitus: A retrospective study. AB - OBJECTIVE: To investigate the risk factors for developing GDM among Taiwanese pregnant women. DESIGN: A retrospective cohort and case-control study. SETTING: At a medical centre in Southern Taiwan. PARTICIPANTS: The hospitalised pregnant women who were diagnosed with either GDM or normal glucose tolerance (NGT) between 1997 and 2011. The glucose tolerance test results were interpreted according to criteria established by the National Diabetes Data Group for GDM. Participants were divided into either a GDM group (case group) or a normal glucose tolerance (NGT) group (control group) in order to determine the risk factors for GDM. MEASUREMENTS: With a retrospective chart review, data regarding demographics, a family history of diabetes, history of gestation, and physiological index for pre- and postpregnancy periods were collected. chi2 tests and independent t tests were used to examine the correlations between demographic characteristics and GDM. Stepwise multivariate logistic regression was used to determine the factors associated with GDM. FINDINGS: The results of the comparison between the GDM group (n=106) and the NGT group (n=406) showed that the risk factors for GDM were maternal age, education, a family history of diabetes, and prepregnancy body mass index (BMI). KEY CONCLUSION AND IMPLICATION FOR PRACTICE: Older age, lower levels of education, a family history of diabetes, and higher prepregnancy BMI were significant risk factors for GDM. In addition to performing risk factor assessment, health care providers should proactively promote the importance of GDM screening to pregnant women at their first antenatal visit. PMID- 27705837 TI - Perspectives on enhancing international practical training of students in health and social care study programs - A qualitative descriptive case study. AB - BACKGROUND: Internationalization of practical training in health and social care study programs is an important aspect of higher education. However, field mentors' and classroom teachers' competence in guiding culturally diverse students varies widely in European countries, and the majority does not have enough training in guiding foreign students. OBJECTIVES: This study aimed to examine which factors enhance the efficacy of international practical placement experiences in health and social care study programs. DESIGN: A qualitative descriptive case study design was used. SETTINGS: The study was conducted at six higher education institutions-two in Finland and one in Croatia, Estonia, the Netherlands and Slovenia. PARTICIPANTS: A convenience sample of 14 mentors, 15 teachers and 14 students with international experiences from six higher education institutions which are part of the Bologna Process was recruited. METHODS: The data were collected from six focus groups using a semi-structured questionnaire based on a literature review. Each higher education institution conducted one group interview that was tape-recorded, transcribed and analysed for themes. RESULTS: Participants made several recommendations for enhancing the practical placement experience of students, teachers, and mentors. Most recommendations dealt with practical supervision of students. Three major themes noted were: 'Attitudes towards internationalization of practical placements', 'Factors impacting the international placement experience', and 'Pedagogical methods used and structural support available for internationalization.' CONCLUSIONS: The study highlights the need for strengthening the multicultural knowledge and skills of mentors and teachers. The findings provide practical guidelines for improving the international placement experience across health and social care fields. PMID- 27705838 TI - Luteinizing hormone-follicle stimulating hormone ratio as biological predictor of post-partum depression. AB - BACKGROUND: Post-partum depression (PPD) is the common adverse outcome of child bearing which affects the wellbeing of both mother and newborn and has long-term effects. Hence, reliable potential biological tests for early detection of PPD are essential. Follicle stimulating hormone (FSH) and luteinizing hormone (LH) were associated with depressive disorders and the present study estimated the levels of serum FSH, LH in postpartum depression and explored them as predictive biomarkers in the development of PPD. METHODS: In this nested case control study done at a tertiary care hospital in South India, 450 postpartum women were screened at 6th week post-delivery for PPD. Socio-demographic and clinical data were recorded and depressive symptoms were assessed using Edinburgh Postnatal Depression Scale (EPDS). Out of 450 subjects screened, 100 women with depressive symptoms were categorized as cases and 100 controls were selected from the remaining subjects matching for age and BMI with cases. Serum levels of FSH and LH were measured using direct competitive immunoassay by chemiluminescene technology. RESULTS: Serum LH/FSH ratio was found to be significantly (p=0.02) low in PPD women when compared to normal postpartum subjects. We also found a significant negative correlation between LH/FSH ratio and EPDS scores. Based on the receiver operating characteristic curve, the optimal cut-off value for serum of LH/FSH levels in predicting postpartum depression was estimated to be 0.22mlU/mL with an AUC of 0.598 (95%CI, 0.291-0.859). CONCLUSION: Our study demonstrated that low LH/FSH ratio after delivery was associated with increased risk for the development of PPD. Low LH/FSH ratio at six-week post delivery can be used as a robust biochemical predictor of post-partum depression. PMID- 27705839 TI - 30-year nationwide trends in incidence of atrial fibrillation in Denmark and associated 5-year risk of heart failure, stroke, and death. AB - BACKGROUND: Long-term nationwide trends in atrial fibrillation (AF) incidence and 5-year outcomes are rare. METHODS: We conducted a population-based cohort study using the Danish National Patient Registry covering all Danish hospitals. We computed standardized incidence rates during 1983-2012. We used Cox regression to estimate hazard ratios (HRs) of heart failure, stroke, and death within 5years, comparing 5-year calendar periods with the earliest period (1983-1987) as reference. RESULTS: We identified 312,420 patients with first-time hospital diagnosed AF. The incidence rate per 100,000person-years increased from 98 in 1983 to 307 in 2012. The mean annual increase during the 30-year study period was 4%, with a 6% increase annually until 2000 and a 1.4% increase annually thereafter. The incidence trends were most pronounced among men and persons above 70years. Among high-risk subgroups, AF incidence was consistently highest in patients with valvular heart disease or heart failure. The rate of heart failure following AF declined by 50% over the entire study period (HR: 0.49, 95% confidence interval (CI): 0.48-0.51) and the mortality rate declined by 40% (HR: 0.62, 95% CI: 0.61-0.63). Within the last two decades, the rate for ischemic stroke declined by 20% (HR 0.81, 95% CI: 0.78-0.84), but increased almost as much for haemorrhagic stroke (HR: 1.14, 95% CI: 1.01-1.29). CONCLUSIONS: The long-term risk of heart failure, ischemic stroke, and death following onset of AF has decreased remarkably over the last three decades. Still, the threefold increased incidence of hospital-diagnosed AF during the same period is a major public health concern. PMID- 27705840 TI - What do patients value about spinal manipulation and home exercise for back related leg pain? A qualitative study within a controlled clinical trial. AB - BACKGROUND: Patient perceptions may influence the effectiveness and utilization of healthcare interventions, particularly for complex health conditions such as sciatica or back-related leg pain (BRLP). OBJECTIVES: To explore BRLP patients' perceptions of spinal manipulative therapy (SMT) and home exercise with advice (HEA). DESIGN: Qualitative study in a controlled clinical trial. METHOD: Semi structured interviews conducted after 12 weeks of treatment asked participants about satisfaction with care and whether treatment was worthwhile. An interdisciplinary research team conducted content analysis using qualitative data analysis software to identify and summarize themes. RESULTS: Of 192 trial participants, 174 (91%) completed interviews (66% female, age 57.0 +/- 11.5 years). Participants identified interactions with providers and staff, perceived treatment effects, and information as key contributors to both their satisfaction and the worthwhile nature of treatment. HEA was liked for its convenience and ability to foster an exercise habit. SMT was liked for specific aspects of the modality (e.g. manipulation, stretching) and provider competency. Most participants reported no dislikes for SMT or HEA, but some noted the dose/time commitment for SMT and discipline of HEA as least liked aspects of the interventions. CONCLUSIONS: The quality of patient-provider interactions, perceived treatment effects, and information sharing influenced BRLP patients' satisfaction with care. Qualitative research describing patients' preferences can facilitate translation of study findings into practice and allow clinicians to tailor treatments to facilitate compliance and satisfaction with care. PMID- 27705841 TI - Human dihydrofolate reductase influences the sensitivity of the malaria parasite Plasmodium falciparum to ketotifen - A cautionary tale in screening transgenic parasites. AB - Ketotifen has recently been reported to inhibit the growth of both asexual and sexual malaria parasites. A parasite transporter, PfgABCG2, has been implicated in its mechanism of action. Human dihydrofolate reductase (hDHFR) is the most commonly used selectable marker to create transgenic Plasmodium falciparum cell lines. Growth assays using transgenic P. falciparum parasites with different selectable markers revealed that the presence of hDHFR rather than the absence of PfgABCG2 is responsible for a shift in the parasite's sensitivity to ketotifen. Employing a range of in vitro assays and liquid chromatography-mass spectrometry we show that ketotifen influences hDHFR activity, but it is not metabolised by the enzyme. Our data also highlights potential pitfalls when functionally characterising transgenic parasites. PMID- 27705842 TI - Beverage-specific patterns of 5+ alcoholic drink consumption by young adults in the U.S. AB - Young adult binge drinking prevalence has been widely researched. However, beverage-specific binge drinking rates for beer, liquor, wine, and wine coolers have not yet been documented for this age group. This study examines consumption of specific beverages (i.e., 5+ drinks in a row in the past two weeks) by young adults aged 19/20. Data from the national Monitoring the Future study were collected one or two years after high school from 2004 to 2014 (n=2004). Logistic regression was used to examine associations between beverage-specific 5+ drinking and gender, race/ethnicity, parent education, college status, and cohort year. Overall 5+ drinking in the past two weeks was reported by 31.4% of young adults. Beverage-specific 5+ drinking was most common with liquor (22.6%) and beer (22.4%), followed by wine (4.5%) and wine coolers (3.0%). Men were more likely than women to engage in 5+ drinking with beer and liquor; women were more likely than men to do so with wine and wine coolers. Beverage-specific patterns differed by college attendance. Compared to four-year college students, two-year college/votech students were less likely to have 5+ drinks of liquor or wine, and more likely to have 5+ wine coolers; those not in college were less likely to have 5+ drinks of liquor and more likely to have 5+ wine coolers. Differences in beverage-specific 5+ drinking by gender and college enrollment suggest that intervention efforts should focus on the beverages that are most commonly consumed at high levels within specific early young adult populations. PMID- 27705843 TI - Alcohol detoxification completion, acceptance of referral to substance abuse treatment, and entry into substance abuse treatment among Alaska Native people. AB - BACKGROUND: Little is known about factors associated with detoxification treatment completion and the transition to substance abuse treatment following detoxification among Alaska Native people. This study examined 3 critical points on the substance abuse continuum of care (alcohol detoxification completion, acceptance of referral to substance abuse treatment, entry into substance abuse treatment following detoxification). METHODS: The retrospective cohort included 383 adult Alaska Native patients admitted to a tribally owned and managed inpatient detoxification unit. Three multiple logistic regression models estimated the adjusted associations of each outcome separately with demographic/psychosocial characteristics, clinical characteristics, use related behaviors, and health care utilization. RESULTS: Seventy-five percent completed detoxification treatment. Higher global assessment functioning scores, longer lengths of stay, and older ages of first alcohol use were associated with completing detoxification. A secondary drug diagnosis was associated with not completing detoxification. Thirty-six percent accepted a referral to substance abuse treatment following detoxification. Men, those with legal problems, and those with a longer length of stay were more likely to accept a referral to substance abuse treatment. Fifty-eight percent had a confirmed entry into a substance abuse treatment program at discharge. Length of stay was the only variable associated with substance abuse treatment entry. CONCLUSIONS: Services like motivational interviewing, counseling, development of therapeutic alliance, monetary incentives, and contingency management are effective in linking patients to services after detoxification. These should be considered, along with the factors associated with each point on the continuum of care when linking patients to follow-up services. PMID- 27705844 TI - Abdominal and pelvic manifestations of Rosai-Dorfman disease: a review of four cases. AB - Rosai-Dorfman disease is a rare disorder of unknown etiology caused by the proliferation of histiocytes within lymph nodes, predominantly in the cervical chain. Extranodal sites may be involved as well, with involvement of nearly every organ system described in the literature. Abdominal and pelvic manifestations of Rosai-Dorfman disease are extremely rare. We present four cases of abdominal and pelvic involvement by Rosai-Dorfman disease, specifically within the biliary tract, pancreas, spleen, and presacral space. Of note, a presacral mass was present in three of the four patients, and although not previously reported in Rosai-Dorfman disease, may suggest the diagnosis in the proper clinical scenario. PMID- 27705845 TI - Inactivation efficiency and mechanism of UV-TiO2 photocatalysis against murine norovirus using a solidified agar matrix. AB - Human norovirus (HuNoV) is the primary cause of viral gastroenteritis worldwide. Fresh blueberries are among high risk foods associated with norovirus related outbreaks. Therefore, it is important to assess intervention strategies to reduce the risk of foodborne illness. The disinfection efficiency of decontamination methods is difficult to evaluate for fruits and vegetables due to an inconsistent degree of contamination and irregular surface characteristics. The inactivation efficiency and mechanism of murine norovirus 1 (MNV-1, a surrogate for HuNoV) was studied on an experimentally prepared solidified agar matrix (SAM) to simulate blueberries using different wavelengths (A, B, C) of UV light both with and without TiO2 photocatalysis (TP). MNV-1 was inoculated on exterior and interior of SAM and inactivation efficiencies of different treatments were investigated using a number of assays. Initial inoculum levels of MNV-1 on the SAM surface and interior were 5.2logPFU/mL. UVC with TiO2 (UVC-TP) achieved the highest level of viral reduction for both externally inoculated and internalized MNV-1. Externally inoculated MNV-1 was reduced to non-detectable levels after UVC-TP treatment for 5min while there was still a 0.9 log viral titer after UVC alone. For internalized MNV-1, 3.2 log and 2.7 log reductions were obtained with UVC-TP and UVC alone treatments for 10min, respectively. The Weibull model was applied to describe the inactivation behavior of MNV-1, and the model showed a good fit to the data. An excellent correlation between the steady-state concentration of OH radicals ([OH]ss) and viral inactivation was quantified using a para chlorobenzoic acid (pCBA) probe compound, suggesting that OH radicals produced in the UV-TP reaction were the major species for MNV-1 inactivation. Transmission electron microscopy images showed that the structure of viral particles was completely disrupted with UVC-TP and UVC alone. SDS-PAGE analysis showed that the major capsid protein VP1 was degraded after UVC-TP and UVC alone. Real-time RT qPCR analysis showed that UVC-TP and UVC alone caused a reduction in the level of viral genomic RNA. Propidium monoazide (PMA) pretreatment RT-qPCR analysis showed that UVC-TP caused damage to the viral capsid protein in addition to viral genomic RNA. UVC both with and without TiO2 was more effective for MNV-1 inactivation than UVB and UVA. Thus, UVC-TP disinfection aimed to reduce levels of food-borne viruses can inactivate viruses present on the surface and internalized in the interior of blueberries. PMID- 27705846 TI - Investigation of the interaction between berberine and nucleosomes in solution: Spectroscopic and equilibrium dialysis approach. AB - Berberine is a natural plant alkaloid with high pharmacological potential. Although its interaction with free DNA has been the subject of several reports, to date there is no work concerning the effect of berberine on nucleoprotein structure of DNA, the nucleosomes. The present study focuses on the binding affinity of berberine to nucleosomes and histone H1 employing various spectroscopic techniques, fluorescence, circular dichroism, thermal denaturation as well as equilibrium dialysis. The results showed that the binding of berberine to nucleosomes is positive cooperative with Ka=5.57*103M-1. Berberine quenched with the chromophores of protein moiety of nucleosomes and reduced fluorescence emission intensity at 335nm with Ksv value of 0.135. Binding of berberine to nucleosomes decreased the absorbance at 210 and 260nm, produced hypochromicity in thermal denaturation profiles and its affinity to nucleoprotein structure of nucleosomes was much higher than to free DNA. Berberine also exhibited high affinity to histone H1 in solution and the binding was positive cooperative with. Ka=3.61*103M-1. Moreover berberine decreased fluorescence emission intensity of H1 by quenching with tyrosine residue in its globular core domain. The circular dichroism profiles demonstrated that the binding of drug induced secondary structural changes in both DNA stacking and histone H1. It is concluded that berberine is genotoxic drug, interacts with nucleosomes and in this process histone H1 is involved to exert its anticancer activity. PMID- 27705847 TI - Tuning the physical properties of organic sensitizers by replacing triphenylamine with new donors for dye sensitized solar cells - a theoretical approach. AB - New donor molecules with low ionization potential have been theoretically designed by replacing the benzene moieties in triphenylamine (TPA) with thiophene as well as furan. The designed new donors also exhibited planar structure, making an angle of 120 degrees around the nitrogen atom that results in resonance effects through pi-bonds of aryl rings. New sensitizers have been theoretically studied using DFT and TD-DFT by adopting these designed donors. UV-Vis absorption spectra, light harvesting ability (LHE) and electron injection ability (DeltaGinject) of the designed sensitizers have been calculated by taking L0 as reference. Orbital overlapping between donor and acceptor facilitates intra molecular charge transfer, thereby increasing the interfacial electron injection from the sensitizer to the semiconductor nanoparticles. Our theoretical results demonstrate that sensitizers DTPA-AA and DFPA-AA have broader absorption and lower DeltaGinject respectively compare to L0, this opens a new way for designing sensitizers for dye sensitized solar cells (DSSCs). All the dyes designed were found to be good light harvesters. PMID- 27705848 TI - Slow-electron velocity-map imaging study of aniline via resonance-enhanced two photon ionization method. AB - Slow electron velocity-map imaging (SEVI) of aniline has been investigated via two-color resonant-enhanced two-photo (1+1') ionization (2C-R2PI) method. A number of vibrational frequencies in the first excited state of neutral (S1) and 2B1 ground electronic state of cation (D0) have been accurately determined. In addition, photoelectron angular distributions (PADs) in the two-step transitions are presented and reveal a near threshold shape resonance in the ionization of aniline. The SEVI spectra taken via various S1 intermediate states provide the detailed vibrational structures of D0 state and directly deduce the accurate adiabatic ionization potential (IP) of 62,271+/-6cm-1. Ab initio calculations excellently reproduce the experimental IP value (Theo. 62,242cm-1). For most vibrational modes, good agreement between theoretical and experimental frequencies in the S0 and D0 states of aniline is obtained to aid us to clearly assign vibrational modes. Especially, the vibrational frequencies calculated at the CASSCF level are much better consistent with experimental data than that obtained using the TDDFT and CIS methods.

AB - The science of the microbiome is arguably one of the hottest topics in medicine, and rightfully so. A deeper understanding of the ecology of the flora in our bodies is providing revolutionary insight beyond the simple form and function of our major parts. This new frontier is dauntingly complex, and most studies focus on details, failing to place these microbial ecosystems within the larger context of evolutionary time and environment. PMID- 27705850 TI - Fate and mass balance of contaminants of emerging concern during wastewater treatment determined using the fractionated approach. AB - Contaminants of emerging concern (CECs) are often poorly removed from wastewater using conventional treatment technologies and there is limited understanding of their fate during treatment. Inappropriate sampling strategies lead to inaccuracies in estimating removals of CECs. In this study, we used the "fractionated approach" that accounts for the residence time distribution (RTD) in treatment units to investigate the fate of 26 target CECs in a municipal wastewater treatment plant (WWTP) that includes primary, secondary and tertiary treatment steps. Prior hydraulic calibration of each treatment unit was performed. Wastewater and sludge samples were collected at different locations along the treatment train and the concentrations of target CECs were measured by liquid chromatography mass spectrometry. The most substantial aqueous removal occurred during activated sludge treatment (up to 99%). Removals were <50% in the primary clarifier and tertiary rotating biological contactors (RBCs) and up to 70% by sand filtration. Mass balance calculations demonstrated that (bio)degradation accounted for up to 50% of the removal in the primary clarifier and 100% in activated sludge. Removal by sorption to primary and secondary sludge was minimal for most CECs. Analysis of the selected metabolites demonstrated that negative removals obtained could be explained by transformations between the parent compound and their metabolites. This study contributes to the growing literature by applying the fractionated approach to calculate removal of different types of CECs across each wastewater treatment step. An additional level of understanding of the fate of CECs was provided by mass balance calculations in primary and secondary treatments. PMID- 27705854 TI - Accurate Lungs Segmentation on CT Chest Images by Adaptive Appearance-Guided Shape Modeling. AB - To accurately segment pathological and healthy lungs for reliable computer-aided disease diagnostics, a stack of chest CT scans is modeled as a sample of a spatially inhomogeneous joint 3D Markov-Gibbs random field (MGRF) of voxel-wise lung and chest CT image signals (intensities). The proposed learnable MGRF integrates two visual appearance sub-models with an adaptive lung shape submodel. The first-order appearance submodel accounts for both the original CT image and its Gaussian scale space (GSS) filtered version to specify local and global signal properties, respectively. Each empirical marginal probability distribution of signals is closely approximated with a linear combination of discrete Gaussians (LCDG), containing two positive dominant and multiple sign-alternate subordinate DGs. The approximation is separated into two LCDGs to describe individually the lungs and their background, i.e., all other chest tissues. The second-order appearance submodel quantifies conditional pairwise intensity dependencies in the nearest voxel 26-neighborhood in both the original and GSS filtered images. The shape submodel is built for a set of training data and is adapted during segmentation using both the lung and chest appearances. The accuracy of the proposed segmentation framework is quantitatively assessed using two public databases (ISBI VESSEL12 challenge and MICCAI LOLA11 challenge) and our own database with, respectively, 20, 55, and 30 CT images of various lung pathologies acquired with different scanners and protocols. Quantitative assessment of our framework in terms of Dice similarity coefficients, 95 percentile bidirectional Hausdorff distances, and percentage volume differences confirms the high accuracy of our model on both our database (98.4+/-1.0%, 2.2+/ 1.0 mm, 0.42+/-0.10%) and the VESSEL12 database (99.0+/-0.5%, 2.1+/-1.6 mm, 0.39+/-0.20%), respectively. Similarly, the accuracy of our approach is further verified via a blind evaluation by the organizers of the LOLA11 competition, where an average overlap of 98.0% with the expert's segmentation is yielded on all 55 subjects with our framework being ranked first among all the state-of-the art techniques compared. PMID- 27705856 TI - Combining Simulated and Experimental Data to Simulate Ultrasonic Array Data From Defects in Materials With High Structural Noise. AB - Ultrasonic nondestructive testing inspections using phased arrays are performed on a wide range of components and materials. All real inspections suffer, to varying extents, from coherent noise, including image artifacts and speckle caused by complex geometries and grain scatter, respectively. By its nature, this noise is not reduced by averaging; however, it degrades the signal-to-noise ratio of defects and ultimately limits their detectability. When evaluating the effectiveness of an inspection, a large pool of data from samples containing a range of different defects are important to estimate the probability of detection of defects and to help characterize them. For a given inspection, coherent noise is easy to measure experimentally but hard to model realistically. Conversely, the ultrasonic response of defects can be simulated relatively easily. This paper proposes a novel method of simulating realistic array data by combining noise free simulations of defect responses with coherent noise taken from experimental data. This removes the need for costly physical samples with known defects to be made and allows for large data sets to be created easily. PMID- 27705855 TI - Nonlinear Imaging of Microbubble Contrast Agent Using the Volterra Filter: In Vivo Results. AB - A nonlinear filtering approach to imaging the dynamics of microbubble ultrasound contrast agents (UCAs) in microvessels is presented. The approach is based on the adaptive third-order Volterra filter (TVF), which separates the linear, quadratic, and cubic components from beamformed pulse-echo ultrasound data. The TVF captures polynomial nonlinearities utilizing the full spectral components of the echo data and not from prespecified bands, e.g., second or third harmonics. This allows for imaging using broadband pulse transmission to preserve the axial resolution and the SNR. In this paper, we present the results from imaging the UCA activity in a 200- [Formula: see text] cellulose tube embedded in a tissue mimicking phantom using a linear array diagnostic probe. The contrast enhancement was quantified by computing the contrast-to-tissue ratio (CTR) for the different imaging components, i.e., B-mode, pulse inversion (PI), and the TVF components. The temporal mean and standard deviation of the CTR values were computed for all frames in a given data set. Quadratic and cubic images, referred to as QB-mode and CB-mode, produced higher mean CTR values than B-mode, which showed improved sensitivity. Compared with PI, they produced similar or higher mean CTR values with greater spatial specificity. We also report in vivo results from imaging UCA activity in an implanted LNCaP tumor with heterogeneous perfusion. The temporal means and standard deviations of the echogenicity were evaluated in small regions with different perfusion levels in the presence and absence of UCA. The in vivo measurements behaved consistently with the corresponding calculations obtained under microflow conditions in vitro. Specifically, the nonlinear VF components produced larger increases in the temporal mean and standard deviation values compared with B-mode in regions with low to relatively high perfusion. These results showed that polynomial filters such as the TVF can provide an important tool for imaging UCA activity in regions with heterogeneous perfusion as is the case in some tumors and ischemic tissues. PMID- 27705857 TI - A Comparison of the Performance of Different Multiline Transmit Setups for Fast Volumetric Cardiac Ultrasound. AB - It was previously demonstrated in 2-D echocardiography that a proper multiline transmit (MLT) implementation can be used to increase frame rate while preserving image quality. Initial findings for extending MLT to 3-D showed that it might address the low spatiotemporal resolution of current volumetric ultrasound systems. However, to date, it remains unclear how much transmit/receive parallelization would be possible using a 3-D MLT system. Therefore, the aim of this paper was to contrast different MLT setups for 3-D imaging by computer simulation in order to determine an optimal tradeoff between the amount of parallelization of an MLT system and the corresponding signal-to-noise ratio of the resulting images. Hereto, the image quality of several MLT setups was estimated by quantifying their crosstalk energy level. The results showed that for the tested setups, 4MLT broad beams and 9MLT narrow beams with Tukey ( alpha = 0.5 ) apodization in transmit and receive give the highest frame rate gain while maintaining an acceptable interbeam interference level. Moreover, although 16MLT narrow beams with Tukey/Tukey ( alpha = 0.5 ) apodization did show more pronounced interbeam interference, its gain in frame rate might outweigh its predicted loss in image quality. As such both 9MLT and 16MLT narrow beams were tested experimentally. For both systems, four receive lines were reconstructed from each transmit beam. The contrast-to-noise ratio of these imaging strategies was quantified and compared with the image quality obtained with line-by-line scanning. Despite some expected loss in image quality, the resulting images of the parallelized systems were very competitive to the benchmark, while speeding up the acquisition process by a factor of 36 and 64, respectively. PMID- 27705859 TI - Web Video Event Recognition by Semantic Analysis From Ubiquitous Documents. AB - In recent years, the task of event recognition from videos has attracted increasing interest in multimedia area. While most of the existing research was mainly focused on exploring visual cues to handle relatively small-granular events, it is difficult to directly analyze video content without any prior knowledge. Therefore, synthesizing both the visual and semantic analysis is a natural way for video event understanding. In this paper, we study the problem of Web video event recognition, where Web videos often describe large-granular events and carry limited textual information. Key challenges include how to accurately represent event semantics from incomplete textual information and how to effectively explore the correlation between visual and textual cues for video event understanding. We propose a novel framework to perform complex event recognition from Web videos. In order to compensate the insufficient expressive power of visual cues, we construct an event knowledge base by deeply mining semantic information from ubiquitous Web documents. This event knowledge base is capable of describing each event with comprehensive semantics. By utilizing this base, the textual cues for a video can be significantly enriched. Furthermore, we introduce a two-view adaptive regression model, which explores the intrinsic correlation between the visual and textual cues of the videos to learn reliable classifiers. Extensive experiments on two real-world video data sets show the effectiveness of our proposed framework and prove that the event knowledge base indeed helps improve the performance of Web video event recognition.

AB - Directly using brain signals rather than limbs to steer a vehicle may not only help disabled people to control an assistive vehicle, but also provide a complementary means of control for a wider driving community. In this paper, to simulate and predict driver performance in steering a vehicle with brain signals, we propose a driver brain-controlled steering model by combining an extended queuing network-based driver model with a brain-computer interface (BCI) performance model. Experimental results suggest that the proposed driver brain controlled steering model has performance close to that of real drivers with good performance in brain-controlled driving. The brain-controlled steering model has potential values in helping develop a brain-controlled assistive vehicle. Furthermore, this study provides some insights into the simulation and prediction of the performance of using BCI systems to control other external devices (e.g., mobile robots).

AB - Solution-processed bovine serum albumin conjugated with ZnO nanosphere (BCZ) have been synthesized for ultra-low level mercury ion detection. Simple drop casting technique was adopted to fabricate such a mercury ion (Hg2+) detection scheme. Morphological and optical characterization of the BCZ was performed by Transmission Electron Microscopy (TEM), UV-Vis and Fluorescence spectroscopic technique prior to device fabrication. The working principle of the BCZ device for Hg2+ detection depends upon the variation of conductance with various concentration of Hg2+. An extensive study was carried out to investigate the effect of Hg2+ upon transport properties of BCZ. The ultra-low level of Hg2+ sensing was performed using this electrical detection technique. More importantly, this proposed BCZ based detection technique is found to be simple, inexpensive and very fast in responding (response time ~ 2.5 s) to heavy metal ion with a limit of detection (LOD) 0.03 fg/ml (S/ [Formula: see text]3). PMID- 27705864 TI - Delay-Dependent Global Exponential Stability for Delayed Recurrent Neural Networks. AB - This paper deals with the global exponential stability for delayed recurrent neural networks (DRNNs). By constructing an augmented Lyapunov-Krasovskii functional and adopting the reciprocally convex combination approach and Wirtinger-based integral inequality, delay-dependent global exponential stability criteria are derived in terms of linear matrix inequalities. Meanwhile, a general and effective method on global exponential stability analysis for DRNNs is given through a lemma, where the exponential convergence rate can be estimated. With this lemma, some global asymptotic stability criteria of DRNNs acquired in previous studies can be generalized to global exponential stability ones. Finally, a frequently utilized numerical example is carried out to illustrate the effectiveness and merits of the proposed theoretical results. PMID- 27705863 TI - An Integrated Approach to Characterize the Behavior of a Human Fingertip in Contact with a Silica Window. AB - Understanding the mechanisms of human tactual perception represents a challenging task in haptics and humanoid robotics. A classic approach to tackle this issue is to accurately and exhaustively characterize the mechanical behavior of human fingertip. The output of this characterization can then be exploited to drive the design of numerical models, which can be used to investigate in depth the mechanisms of human sensing. In this work, we present a novel integrated measurement technique and experimental set up for in vivo characterization of the deformation of the human fingertip at contact, in terms of contact area, force, deformation, and pressure distribution. The device presented here compresses the participant's fingertip against a flat surface, while the aforementioned measurements are acquired and experimental parameters such as velocity, finger orientation, and displacement (indentation) controlled. Experimental outcomes are then compared and integrated with the output of a 3D finite element (FE) model of the human fingertip, built upon existing validated models. The agreement between numerical and experimental data represents a validation for our approach. PMID- 27705868 TI - The Twist Tensor Nuclear Norm for Video Completion. AB - In this paper, we propose a new low-rank tensor model based on the circulant algebra, namely, twist tensor nuclear norm (t-TNN). The twist tensor denotes a three-way tensor representation to laterally store 2-D data slices in order. On one hand, t-TNN convexly relaxes the tensor multirank of the twist tensor in the Fourier domain, which allows an efficient computation using fast Fourier transform. On the other, t-TNN is equal to the nuclear norm of block circulant matricization of the twist tensor in the original domain, which extends the traditional matrix nuclear norm in a block circulant way. We test the t-TNN model on a video completion application that aims to fill missing values and the experiment results validate its effectiveness, especially when dealing with video recorded by a nonstationary panning camera. The block circulant matricization of the twist tensor can be transformed into a circulant block representation with nuclear norm invariance. This representation, after transformation, exploits the horizontal translation relationship between the frames in a video, and endows the t-TNN model with a more powerful ability to reconstruct panning videos than the existing state-of-the-art low-rank models. PMID- 27705872 TI - Multisensor-Based Periodic Estimation in Sensor Networks With Transmission Constraint and Periodic Mixed Storage. AB - In this paper, we consider a periodic estimation problem in sensor networks with a shared communication channel. The transmission constraint is inevitable in a single-channel-based sensor network if the sensors are heterogeneous or deployed far away from each other. A novel stochastic competitive transmission strategy is presented to deal with the transmission constraint, such that the sensors communicate with the fusion center (FC) in a strict asynchronous manner. A periodic mixed storage strategy combing the zero-input and the hold-input mechanisms is presented to describe periodic updating of the stored information in the sensors' buffers. A recursive Kalman filtering algorithm is derived for the FC to periodically generate estimates of state variables describing an object by using a linear continuous-time stochastic model. Two simulation examples are presented to show the effectiveness of the proposed results. PMID- 27705873 TI - Spectral Contextual Classification of Hyperspectral Imagery With Probabilistic Relaxation Labeling. AB - In this paper, a spectral-spatial classification framework based on probabilistic relaxation labeling using compatibility coefficients is proposed for hyperspectral images. It is a two-stage classifier that uses maximum a posteriori (MAP) estimation to maximize posterior probabilities of classification map obtained in first stage to incorporate spatial information for better classification accuracy. Two different forms of compatibility coefficients based on correlation and mutual information are used for MAP estimation. The initial probability estimates are obtained from probabilistic support vector machine (SVM) classifier. The combination of SVM with MAP estimation is investigated and compared with benchmark Markov random field and extended morphological profile based approaches and some other recent methods. The experimental results are presented for three airborne hyperspectral images. The results reveal that incorporation of contextual information with both forms of compatibility coefficients statistically significantly improved SVM results. The compatibility coefficients based on correlation produced the best results among the relaxation methods outperforming many existing methods. PMID- 27705875 TI - Robust Learning Control Design for Quantum Unitary Transformations. AB - Robust control design for quantum unitary transformations has been recognized as a fundamental and challenging task in the development of quantum information processing due to unavoidable decoherence or operational errors in the experimental implementation of quantum operations. In this paper, we extend the systematic methodology of sampling-based learning control (SLC) approach with a gradient flow algorithm for the design of robust quantum unitary transformations. The SLC approach first uses a "training" process to find an optimal control strategy robust against certain ranges of uncertainties. Then a number of randomly selected samples are tested and the performance is evaluated according to their average fidelity. The approach is applied to three typical examples of robust quantum transformation problems including robust quantum transformations in a three-level quantum system, in a superconducting quantum circuit, and in a spin chain system. Numerical results demonstrate the effectiveness of the SLC approach and show its potential applications in various implementation of quantum unitary transformations. PMID- 27705876 TI - A Neurodynamic Model to Solve Nonlinear Pseudo-Monotone Projection Equation and Its Applications. AB - In this paper, a neurodynamic model is given to solve nonlinear pseudo-monotone projection equation. Under pseudo-monotonicity condition and Lipschitz continuous condition, the projection neurodynamic model is proved to be stable in the sense of Lyapunov, globally convergent, globally asymptotically stable, and globally exponentially stable. Also, we show that, our new neurodynamic model is effective to solve the nonconvex optimization problems. Moreover, since monotonicity is a special case of pseudo-monotonicity and also since a co-coercive mapping is Lipschitz continuous and monotone, and a strongly pseudo-monotone mapping is pseudo-monotone, the neurodynamic model can be applied to solve a broader classes of constrained optimization problems related to variational inequalities, pseudo convex optimization problem, linear and nonlinear complementarity problems, and linear and convex quadratic programming problems. Finally, several illustrative examples are stated to demonstrate the effectiveness and efficiency of our new neurodynamic model. PMID- 27705877 TI - Single-Image Distance Measurement by a Smart Mobile Device. AB - Existing distance measurement methods either require multiple images and special photographing poses or only measure the height with a special view configuration. We propose a novel image-based method that can measure various types of distance from single image captured by a smart mobile device. The embedded accelerometer is used to determine the view orientation of the device. Consequently, pixels can be back-projected to the ground, thanks to the efficient calibration method using two known distances. Then the distance in pixel is transformed to a real distance in centimeter with a linear model parameterized by the magnification ratio. Various types of distance specified in the image can be computed accordingly. Experimental results demonstrate the effectiveness of the proposed method. PMID- 27705878 TI - Cardiac calcified amorphous tumors: CT and MRI findings. AB - PURPOSE: We aimed to evaluate computed tomography (CT) and magnetic resonance imaging (MRI) findings of cardiac calcified amorphous tumors (CATs). METHODS: CT and MRI findings of cardiac CATs in 12 patients were included. We retrospectively examined patient demographics, location, size, shape configuration, imaging features, calcification distribution of tumors, and accompanying medical problems. RESULTS: There was a female predominance (75%), with a mean age at presentation of 65 years. Patients were mostly asymptomatic on presentation (58.3%). The left ventricle of the heart was mostly involved (91%). CT findings of CATs were classified as partial calcification with a hypodense mass in four patients or a diffuse calcified form in eight. Calcification was predominant with large foci appearance as in partially calcified masses. On T1- and T2-weighted magnetic resonance images, CATs appeared hypointense and showed no contrast enhancement. CONCLUSION: The shape and configuration of cardiac CATs are variable with a narrow spectrum of CT and MRI findings, but large foci in a partially calcified mass or diffuse calcification of a mass on CT is very important in the diagnosis of cardiac CATs. Masses show a low signal intensity on T1- and T2 weighted images with no contrast enhancement on MRI. PMID- 27705879 TI - Local tumor progression patterns after radiofrequency ablation of colorectal cancer liver metastases. AB - PURPOSE: We aimed to evaluate patterns of local tumor progression (LTP) after radiofrequency ablation (RF ablation) of colorectal cancer liver metastases (CRCLM) and to highlight the percentage of LTP not attributable to lesion size or RF ablation procedure-related factors (heat sink or insufficient ablation margin). METHODS: CRCLM treated by RF ablation at a single tertiary care center from 2004-2012, with a minimum of six months of postprocedure follow-up, were included in this retrospective study. LTP morphology was classified as focal nodular (<90 degrees of ablation margin), circumferential (>270 degrees ), or crescentic (90 degrees -270 degrees ). Initial metastasis size, minimum ablation margin size, morphology of LTP, presence of a heat sink, and time to progression were recorded independently by two radiologists. RESULTS: Thirty-two of 127 RF ablation treated metastases (25%) with a mean size of 23 mm (standard deviation 12 mm) exhibited LTP. Fifteen of 32 LTPs (47%) were classified as focal nodular, with seven having no procedure-related factor to explain recurrence. Ten of 32 LTPs (31%) were circumferential, with four having no procedure-related factor to explain recurrence. Seven of 32 LTPs (22%) were crescentic, with two having no procedure-related factor to explain recurrence. Of the 13 lesions without any obvious procedure-related reason for LTP, six (46%) were <3 cm in size. CONCLUSION: Although LTP in RF ablation treated CRCLM can often be explained by procedure-related factors or size of the lesion, in this study up to six (5%) of the CRCLM we treated showed LTP without any reasonable cause. PMID- 27705881 TI - Decomposition analysis of the waste generation and management in 30 European countries. AB - An often suggested method for waste prevention is substitution of currently-used materials with materials which are less bulky, contain less hazardous components or are easier to recycle. For policy makers it is important to have tools available that provide information on the impact of this substitution on the changes in total amounts of waste generated and managed. The purpose of this paper is to see how much changes in the mix of 15 waste streams generated in eight economic sectors from 30 European countries have influenced the amounts of waste generated and managed in the period 2004-2012. In order to determine these impacts, two variations of the logarithmic mean Divisia index (LMDI) analysis model were developed and applied. The results show that the changes in the mix of waste streams in most cases did not have a considerable influence on the changes in the amounts of generated waste. In the analyses of waste sent for landfill, incineration without energy recovery, incineration with energy recovery and recovery other than energy recovery, the results also show that the changes in the mix of waste streams in most cases did not have the expected/desired influence on the changes in the amounts of managed waste. This paper provides an example on the possibilities of applying the LMDI analysis as a tool for quantifying the potential of effects which implemented or planned measures could have on the changes in waste management systems. PMID- 27705880 TI - Radiologic findings of screen-detected cancers in an organized population-based screening mammography program in Turkey. AB - PURPOSE: Bahcesehir Breast Cancer Screening Program is a population based organized screening program in Turkey, where asymptomatic women aged 40-69 years are screened biannually. In this prospective study, we aimed to determine the mammographic findings of screen-detected cancers and discuss the efficacy of breast cancer screening in a developing country. METHODS: A total of 6912 women were screened in three rounds. The radiologic findings were grouped as mass, focal asymmetry, calcification, and architectural distortion. Masses were classified according to shape, border, and density. Calcifications were grouped according to morphology and distribution. Cancers were grouped according to the clinical stage. RESULTS: Seventy cancers were detected with an incidence of 4.8/1000. Two cancers were detected in other centers and three were not visualized mammographically. Mammographic presentations of the remaining 65 cancers were mass (47.7%, n=31), calcification (30.8%, n=20), focal asymmetry (16.9%, n=11), architectural distortion (3.1%, n=2), and skin thickening (1.5%, n=1). The numbers of stage 0, 1, 2, 3, and 4 cancers were 13 (20.0%), 34 (52.3%), 14 (21.5%), 3 (4.6%), and 1 (1.5%), respectively. The numbers of interval and missed cancers were 5 (7.4%) and 7 (10.3%), respectively. CONCLUSION: A high incidence of early breast cancer has been detected. The incidence of missed and interval cancers did not show major differences from western screening trials. We believe that this study will pioneer implementation of efficient population-based mammographic screenings in developing countries. PMID- 27705882 TI - The influence of residents' behaviour on waste electrical and electronic equipment collection effectiveness. AB - Government agencies have implemented regulations to reduce the volume of waste electrical and electronic equipment to protect the environment and encourage recycling. The effectiveness of systems through which waste electrical and electronic equipment is collected and recycled depends on (a) the development and operation of new programmes to process this material and (b) on information dissemination programmes aimed at manufacturers, retail sellers, and the consuming public. This study analyses these two elements. The main focus is to better understand household residents' behaviour in regards to the proper methods of handling waste electrical and electronic equipment and possible storage of the obsolete equipment that brings disturbances with collection of the waste equipment. The study explores these issues depending on size of municipality and the household residents' knowledge about legal methods of post-consumer management of waste electrical and electronic equipment in Poland, where the collection rate of that type of waste is about 40% of the total mass of waste electrical and electronic equipment appearing in the market.The research was informed by various sources of information, including non-government organisations, Inspectorate of Environmental Protection and Central Statistics Office in Poland, questionnaires, and interviews with the household residents. The questionnaires were distributed to daytime and vocational students from different universities and the customers of an electronic equipment superstore. The results show that a resident's behaviour in regards to the handling of obsolete waste electrical and electronic equipment can significantly reduce the collection rate, especially when the waste is discarded improperly - mixed with municipal waste or sold in scrapyards. It is possible to identify points that are necessary to be improved to achieve a higher collection rate. PMID- 27705883 TI - Effective plots to assess bias and precision in method comparison studies. AB - Bland and Altman's limits of agreement have traditionally been used in clinical research to assess the agreement between different methods of measurement for quantitative variables. However, when the variances of the measurement errors of the two methods are different, Bland and Altman's plot may be misleading; there are settings where the regression line shows an upward or a downward trend but there is no bias or a zero slope and there is a bias. Therefore, the goal of this paper is to clearly illustrate why and when does a bias arise, particularly when heteroscedastic measurement errors are expected, and propose two new plots, the "bias plot" and the "precision plot," to help the investigator visually and clinically appraise the performance of the new method. These plots do not have the above-mentioned defect and still are easy to interpret, in the spirit of Bland and Altman's limits of agreement. To achieve this goal, we rely on the modeling framework recently developed by Nawarathna and Choudhary, which allows the measurement errors to be heteroscedastic and depend on the underlying latent trait. Their estimation procedure, however, is complex and rather daunting to implement. We have, therefore, developed a new estimation procedure, which is much simpler to implement and, yet, performs very well, as illustrated by our simulations. The methodology requires several measurements with the reference standard and possibly only one with the new method for each individual. PMID- 27705885 TI - The preanalytical stability of glucagon as measured by liquid chromatography tandem mass spectrometry and two commercially available immunoassays. AB - Background One of the main challenges in the measurement of glucagon is the premise that it is unstable in human plasma. Traditionally, protease inhibitors have been used to prevent its degradation; however, their use is controversial. Here, we investigated the optimal method of sample collection for glucagon, with measurement by liquid chromatography tandem mass spectrometry (LC-MS/MS) and two commercially available immunoassays. Methods Blood from healthy fasting volunteers (n = 10) was processed under a variety of preanalytical conditions including collection in EDTA vs. lithium heparin tubes and the addition of aprotinin and/or a dipeptidyl-peptidase IV (DPPIV) inhibitor. Additionally, the effect of freeze thaw was assessed. Plasma glucagon concentrations were measured by LC-MS/MS and two commercially available immunoassays (HTRF(r) sandwich immunoassay, Cisbio and Milliplex MAP Human Metabolic Hormone Panel, Merck Millipore). Results A systematic bias of Milliplex > LC-MS/MS > HTRF was noted and plasma glucagon concentrations were significantly different between methods (Milliplex vs. LC-MS/MS P < 0.01; Milliplex vs. HTRF P < 0.0001; LC-MS/MS vs. HTRF P < 0.001). The addition of aprotinin, DPPIV inhibitor or a combination of aprotinin and DPPIV inhibitor had no effect on plasma glucagon concentrations when compared to 'non-stabilized' samples or each other. Whether samples were taken in EDTA tubes or lithium heparin tubes made no difference to plasma glucagon concentrations. These findings were consistent for all three methods. Plasma glucagon concentrations were not significantly different after two freeze thaw cycles (performed on samples in EDTA tubes containing aprotinin and DPPIV inhibitor). Conclusions This study demonstrates that glucagon is stable in both EDTA and lithium heparin tubes when stored at -80C. Furthermore, the addition of aprotinin and DPPIV inhibitors is unnecessary. PMID- 27705884 TI - Unified approach for extrapolation and bridging of adult information in early phase dose-finding paediatric studies. AB - The number of trials conducted and the number of patients per trial are typically small in paediatric clinical studies. This is due to ethical constraints and the complexity of the medical process for treating children. While incorporating prior knowledge from adults may be extremely valuable, this must be done carefully. In this paper, we propose a unified method for designing and analysing dose-finding trials in paediatrics, while bridging information from adults. The dose-range is calculated under three extrapolation options, linear, allometry and maturation adjustment, using adult pharmacokinetic data. To do this, it is assumed that target exposures are the same in both populations. The working model and prior distribution parameters of the dose-toxicity and dose-efficacy relationships are obtained using early-phase adult toxicity and efficacy data at several dose levels. Priors are integrated into the dose-finding process through Bayesian model selection or adaptive priors. This calibrates the model to adjust for misspecification, if the adult and pediatric data are very different. We performed a simulation study which indicates that incorporating prior adult information in this way may improve dose selection in children. PMID- 27705886 TI - Alcohol consumption reduces HbA1c and glycated albumin concentrations but not 1,5 anhydroglucitol. AB - Background The effect of alcohol consumption on glycaemic control indicators is not well known. In this study, we studied the effect of alcohol consumption on the plasma glucose and glycaemic control indicators in non-diabetic men. Methods The study enrolled 300 non-diabetic men who received a complete medical checkup (age: 52.8 +/- 6.5 years, body mass index: 24.4 +/- 2.8 kg/m2). The subjects were divided into four groups by the amount of alcohol consumed, and the plasma glucose, HbA1c, glycated albumin (GA) and 1,5-anhydroglucitol (1,5-AG) concentrations of the groups were compared. Results As the level of alcohol consumption increased, significantly high concentrations of fasting plasma glucose (FPG) were observed, and the oral glucose tolerance test 2-h plasma glucose concentrations tended to rise. While no significant effect of alcohol consumption on HbA1c, 1,5-AG, and the 1,5-AG/FPG ratio was observed, the HbA1c/FPG ratio, GA and the GA/FPG ratio exhibited significantly low values as the level of alcohol consumption increased. In stepwise multivariate regression analysis, alcohol consumption was a significant negative independent variable for HbA1c and GA, but not for 1,5-AG. Conclusions As the level of alcohol consumption increased, the plasma glucose concentrations rose, but the HbA1c and GA concentrations were lower compared with the plasma glucose concentrations. These findings suggest that alcohol consumption may reduce HbA1c and GA concentrations, but not 1,5-AG. PMID- 27705887 TI - Chitotriosidase enzyme activity: is this a possible chronic inflammation marker in children with common variable immunodeficiency and early atherosclerosis? AB - Background Common variable immunodeficiency is a rare clinically symptomatic primary immunodeficiency disorder which manifests a wide variability of symptoms, complications. Atherosclerosis in common variable immunodeficiency patients has not been investigated yet contrary to other severe clinical complications. We aimed to investigate the chitotriosidase enzyme's role as an inflammation and atherosclerosis marker in paediatric common variable immunodeficiency patients. Methods Common variable immunodeficiency patients (n = 24) and healthy controls (n = 23) evaluated for chitotriosidase activity with other inflammation markers (hsCRP, myeloperoxidase, serum amyloid A, ferritin), lipid profile and echocardiographic findings (carotid artery intima media thickness - cIMT, brachial artery flow-mediated vazodilatation - FMD%). Results In patients, the mean chitotriosidase activity (8.98 +/- 6.28) was significantly higher than the controls (5.17 +/- 3.42) ( P = 0.014). Chitotriosidase showed positive relation with hs-CRP ( P = 0.011) and SAA ( P = 0.011) but had no relation with ferritin ( P = 0.155), HDL ( P = 0.152) or LDL-cholesterol ( P = 0.380). Mean cIMT increased in patients compared with the controls ( P < 0.001) but did not show any relation with chitotriosidase ( P = 0.546). FMD% decreased in patients ( P < 0.001) also showing no relation with chitotriosidase ( P = 0.298). Ventricular myocardial performance indexes had no significant difference, but RVEF% decreased in patients ( P = 0.043). Conclusions High chitotriosidase activity in common variable immunodeficiency patients demonstrated in vivo the presence of activated macrophages indicating ongoing inflammation. Echocardiographic diastolic functional deficiency, increased cIMT and decreased FMD% may be accepted as early atherosclerotic findings, but none of them showed relationship with chitotriosidase activities. PMID- 27705889 TI - Impact of Proximal Cap Ambiguity on Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention: Insights From a Multicenter US Registry. AB - OBJECTIVES: We sought to determine the impact of proximal cap ambiguity on procedural techniques and outcomes for coronary chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: We examined the clinical and angiographic characteristics and outcomes of 1021 CTO-PCIs performed between 2012 and 2015 at 11 United States centers. RESULTS: Proximal cap ambiguity was present in 31% of target lesions and was associated with increased clinical and angiographic complexity (prior coronary artery bypass graft surgery: 43% vs 33%; P=.01; moderate/severe calcification 66% vs 51%; P<.001) and lower technical success (85% vs 93%; P<.001) and procedural success (84% vs 91%; P=.01), but similar incidence of major adverse cardiac events (3.2% vs 2.9%; P=.77). A retrograde approach was more commonly utilized among cases with proximal cap ambiguity (68% vs 33%; P<.001), and was more likely to be the initial (39% vs 13%; P<.001) and successful approach (42% vs 20%; P<.001). Proximal cap ambiguity was associated with increased use of intravascular ultrasound (49% vs 36%; P=.01) and contrast (281 mL vs 250 mL; P<.001), higher air kerma radiation dose (4.0 Gy vs 3.0 Gy; P<.001), and longer procedure time (161 min vs 119 min; P<.001). CONCLUSIONS: Proximal cap ambiguity is present in one-third of CTO-PCI target lesions and is associated with lower success rates, higher utilization of the retrograde approach, and lower procedural efficiency, but no significant difference in the incidence of major adverse cardiac events. PMID- 27705890 TI - Influence of Human Immunodeficiency Virus Seropositive Status on the In-Hospital Management and Outcomes of Patients Presenting With Acute Myocardial Infarction. AB - OBJECTIVES: Human immunodeficiency virus (HIV) seropositive individuals are predisposed to acute myocardial infarction (AMI). We sought to evaluate management strategies and outcomes of AMI in patients with HIV in the contemporary era. METHODS: We analyzed data from the National Inpatient Sample from 2002 to 2011 for patients admitted with AMI with or without HIV. Propensity score matching was used to identify HIV seropositive AMI patients with similar characteristics who were managed invasively (cardiac catheterization, percutaneous coronary intervention [PCI], or coronary artery bypass graft surgery [CABG]) or conservatively. The primary outcome was in-hospital all-cause mortality. RESULTS: Among 1,363,570 patients admitted with AMI, 3788 (0.28%) were HIV seropositive. The frequency of HIV diagnosis among AMI patients increased over time (0.20% in 2002 to 0.35% in 2011; P for trend <.001). Patients with HIV had lower odds of invasive management (adjusted odds ratio [OR], 0.59; 95% confidence interval [CI], 0.55-0.65) and were less likely to undergo CABG (OR, 0.66; 95% CI, 0.57-0.76) or receive drug-eluting stents (OR, 0.83; 95% CI, 0.76 0.92) than HIV-seronegative patients. Patients with HIV had higher in-hospital mortality (adjusted OR, 1.36; 95% CI, 1.13-1.64) than those without HIV. In a propensity-matched cohort of 1608 patients with HIV treated for AMI with invasive vs conservative management, invasive management was associated with lower in hospital mortality (3.0% vs 8.2%; P<.001; OR, 0.34; 95% CI, 0.21-0.56). CONCLUSIONS: Disparities exist in management of AMI by HIV status. HIV seropositive patients were less likely to receive invasive management, CABG, and drug-eluting stents, and had higher in-hospital mortality vs patients without HIV. PMID- 27705888 TI - Randomized trial of switching from prescribed non-selective non-steroidal anti inflammatory drugs to prescribed celecoxib: the Standard care vs. Celecoxib Outcome Trial (SCOT). AB - Background: Selective cyclooxygenase-2 inhibitors and conventional non-selective non-steroidal anti-inflammatory drugs (nsNSAIDs) have been associated with adverse cardiovascular (CV) effects. We compared the CV safety of switching to celecoxib vs. continuing nsNSAID therapy in a European setting. Method: Patients aged 60 years and over with osteoarthritis or rheumatoid arthritis, free from established CV disease and taking chronic prescribed nsNSAIDs, were randomized to switch to celecoxib or to continue their previous nsNSAID. The primary endpoint was hospitalization for non-fatal myocardial infarction or other biomarker positive acute coronary syndrome, non-fatal stroke or CV death analysed using a Cox model with a pre-specified non-inferiority limit of 1.4 for the hazard ratio (HR). Results: In total, 7297 participants were randomized. During a median 3 year follow-up, fewer subjects than expected developed an on-treatment (OT) primary CV event and the rate was similar for celecoxib, 0.95 per 100 patient years, and nsNSAIDs, 0.86 per 100 patient-years (HR = 1.12, 95% confidence interval, 0.81-1.55; P = 0.50). Comparable intention-to-treat (ITT) rates were 1.14 per 100 patient-years with celecoxib and 1.10 per 100 patient-years with nsNSAIDs (HR = 1.04; 95% confidence interval, 0.81-1.33; P = 0.75). Pre-specified non-inferiority was achieved in the ITT analysis. The upper bound of the 95% confidence limit for the absolute increase in OT risk associated with celecoxib treatment was two primary events per 1000 patient-years exposure. There were only 15 adjudicated secondary upper gastrointestinal complication endpoints (0.078/100 patient-years on celecoxib vs. 0.053 on nsNSAIDs OT, 0.078 vs. 0.053 ITT). More gastrointestinal serious adverse reactions and haematological adverse reactions were reported on nsNSAIDs than celecoxib, but more patients withdrew from celecoxib than nsNSAIDs (50.9% patients vs. 30.2%; P < 0.0001). Interpretation: In subjects 60 years and over, free from CV disease and taking prescribed chronic nsNSAIDs, CV events were infrequent and similar on celecoxib and nsNSAIDs. There was no advantage of a strategy of switching prescribed nsNSAIDs to prescribed celecoxib. This study excluded an increased risk of the primary endpoint of more than two events per 1000 patient-years associated with switching to prescribed celecoxib.

PMID- 27705891 TI - Comparison of Percutaneous Closure Versus Surgical Femoral Cutdown for Decannulation of Large-Sized Arterial and Venous Access Sites in Adults After Successful Weaning of Veno-Arterial Extracorporeal Membrane Oxygenation. AB - OBJECTIVE: Surgical femoral cutdown for decannulation after veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is considered standard practice. However, access-site complications with this technique are not rare. The objective of this study is to evaluate feasibility, safety, and efficacy of a complete percutaneous decannulation procedure after VA-ECMO compared with the conventional surgical cutdown approach. METHODS: In 35 patients who were successfully weaned from VA-ECMO support, femoral artery and vein access sites were closed using a completely percutaneous approach in 15 patients, whereas 20 patients had conventional surgical cutdown for access-site closure. Data concerning all 35 patients were collected retrospectively and analyzed regarding immediate vascular closure success, associated complications, and clinical outcomes. RESULTS: Technical deployment success of the percutaneous vascular closure devices was achieved in all patients. Immediate success of closure was achieved more frequently in the surgical group (29% vs 100%; P<.05). Severe wound complications requiring surgery occurred only in the surgical group (0% vs 35%; P=NS). Surgical cutdown was associated with a significantly greater need for transfusion of packed red blood cells (1.6 +/- 1.4 vs 2.2 +/- 1.2; P<.05). Mean hospital stay was shorter in the percutaneous group (32 +/- 18 days vs 36 +/- 12 days; P=NS). One patient in the surgical group complained about sustained paresthesia after discharge. CONCLUSIONS: Complete percutaneous closure of the femoral access site after VA-ECMO is feasible, effective, and safe when compared with conventional surgical closure and performed by experienced operators. PMID- 27705892 TI - Sapien 3 Transcatheter Aortic Valve Implantation With Moderate or Without Predilation. AB - OBJECTIVES: Aortic valve preparation with balloon aortic valvuloplasty (BAV) has been previously considered mandatory during transcatheter aortic valve implantation (TAVI) procedures. BAV-inherent risks including stroke, conduction abnormalities, and reduced device profile size established the rationale for safe valve deployment without the need for aggressive valve preparation. We investigate the feasibility and safety of performing Sapien 3 (S3; Edwards Lifesciences) balloon-expandable TAVI with moderate or without predilation (PD). METHODS: We examined consecutive patients with severe aortic stenosis who underwent S3-TAVI at our institution. Overall, 119 patients underwent TAVI without PD and 126 with moderate PD (mean valvuloplasty balloon diameter, 15.3 +/ 2.1 mm). TAVI endpoints and adverse events were considered according to the Valve Academic Research Consortium (VARC)-2 definitions. RESULTS: Device success for the entire cohort was 98.8%. PD rates were similar between groups. Total fluoroscopy time and amount of contrast used were lower in the no PD group (13 min vs 16.2 min [P<.001] and 71.3 mL vs 81 mL [P=.03], respectively). All-cause mortality up to 30 days was 0% (0/119) in the no PD group vs 1.6% (2/126) in the moderate PD group (P=.49). VARC-2 defined complication rates at 30 days including cerebrovascular accident were similar between groups. Overall, there was no significant difference in survival rate between both groups (hazard ratio, 3.6; 95% confidence interval, 0.80-16.2; P=.09). CONCLUSIONS: Balloon-expandable TAVI using the S3 device with moderate or without balloon PD is feasible and safe. Omission of PD in appropriate cases was associated with reduced fluoroscopy time and total contrast used without affecting procedural success.

AB - DNA vaccines have great potential as preventive or therapeutic vaccines against viral, bacterial, or parasitic diseases as well as cancer, and may also be used as gene therapy products. Although many human and veterinary DNA vaccines have been investigated in laboratory trials, only four of these have been approved for commercial use. In this paper an overview of the regulatory requirements for the development of DNA vaccines is given. The regulatory process in EU and USA is described. A discussion concerning the relevance of national regulations on gene technology is included. In addition the main safety concerns associated with DNA vaccines, relating to unwanted side effects in the vaccinated mammal or fish, are presented. Finally, the need for greater openness regarding the assessment information is discussed. PMID- 27705899 TI - Health Advocacy Project: Evaluating the Benefits of Service Learning to Nursing Students and Low Income Individuals Involved in a Community-Based Mental Health Promotion Project. AB - Poverty, along with other factors such as unemployment, work and life stressors, interpersonal violence, and lack of access to high quality health and/or social services all play a role in determining who develops a mental illness and for whom those symptoms persist or worsen. Senior nursing student preparing to enter the field and working in a service learning capacity may be able to influence early recovery and symptom abatement among those most vulnerable to mental illness. A consortium of community stakeholders and researchers collaboratively designed a 10-week mental health promotion project called the Health Advocacy Project (HAP). The project combines case management and system navigation support delivered by trained and highly supervised nursing students to individuals experiencing major depressive disorder (MDD) and/or post-traumatic stress disorder (PTSD). In this article, we present the findings of a qualitative fidelity evaluation that examines the effectiveness of nursing students in delivering the health advocacy intervention at the level and with the intensity originally intended. The findings demonstrate how the services of senior nursing students may be optimized to benefit our healthcare system and populations most at risk for developing MDD and PTSD. PMID- 27705900 TI - Structural diversity in echinocandin biosynthesis: the impact of oxidation steps and approaches toward an evolutionary explanation. AB - Echinocandins are an important group of cyclic non-ribosomal peptides with strong antifungal activity produced by filamentous fungi from Aspergillaceae and Leotiomycetes. Their structure is characterized by numerous hydroxylated non proteinogenic amino acids. Biosynthetic clusters discovered in the last years contain up to six oxygenases, all of which are involved in amino acid modifications. Especially, variations in the oxidation pattern induced by these enzymes account for a remarkable structural diversity among the echinocandins. This review provides an overview of the current knowledge of echinocandin biosynthesis with a special focus on diversity-inducing oxidation steps. The emergence of metabolic diversity is further discussed on the basis of a comprehensive overview of the structurally characterized echinocandins, their producer strains and biosynthetic clusters. For the pneumocandins, echinocandins produced by Glarea lozoyensis, the formation of metabolic diversity in a single organism is analyzed. It is compared to two common models for the evolution of secondary metabolism: the 'target-based' approach and the 'diversity-based' model. Whereas the early phase of pneumocandin biosynthesis supports the target based model, the diversity-inducing late steps and most oxidation reactions best fit the diversity-based approach. Moreover, two types of diversity-inducing steps can be distinguished. Although incomplete hydroxylation is a common phenomenon in echinocandin production and secondary metabolite biosynthesis in general, the incorporation of diverse hydroxyprolines at position 6 is apparently a unique feature of pneumocandin biosynthesis, which stands in stark contrast to the strict selectivity found in echinocandin biosynthesis by Aspergillaceae. The example of echinocandin biosynthesis shows that the existing models for the evolution of secondary metabolism can be well applied to parts of the pathway; however, thus far, there is no comprehensive theory that could explain the entire biosynthesis.

AB - Previously, we reported that height is an indicator of the capacity of vascular repair in elderly men, especially hypertensive men. On the other hand, hemoglobin could act as a possible biochemical index of hypertension-induced vascular damage. However, no studies have clarified the correlation between height and hematopoietic activity. We conducted a cross-sectional study of 249 men aged 65 69 undergoing a general health check-up. Reticulocyte was used to evaluate hematopoietic activity. Because hemoglobin concentration should influence hematopoietic activity, analyses stratified by hemoglobin level were performed. Independent of known cardiovascular risk factors and other hematological parameters (white blood cell count), a significant positive correlation was seen between height and reticulocytes for total subjects and subjects with a high hemoglobin concentration (>=14.5 g/dL), but not in subjects with a low hemoglobin concentration (<14.5 g/dL). The standardized parameter estimates (beta) were beta=0.18, p=0.003 for total subjects, beta=0.28, p=0.001 for subjects with a high hemoglobin concentration, and beta=0.03, p=0.717 for subjects with low hemoglobin. Independently, height is significantly positively correlated with reticulocyte in elderly Japanese men, particularly in men with a high hemoglobin concentration. These results indicate that subjects with a short stature might have lower hematopoietic capacity than those with a high stature.

PMID- 27705904 TI - A cross-sectional study of male and female C57BL/6Nia mice suggests lifespan and healthspan are not necessarily correlated. AB - Lifespan provides a discrete metric that is intuitively appealing and the assumption has been that healthspan is extended concomitant with lifespan. Medicine has been more successful at extending life than preserving health during aging. Interventions that extend lifespan in model organisms do not always result in a corresponding increase in healthspan, suggesting that lifespan and healthspan may be uncoupled. To understand how interventions that extend life affect healthspan, we need measures that distinguish between young and old animals. Here we measured age-related changes in healthspan in male and female C57BL/6JNia mice assessed at 4 distinct ages (4 months, 20 months, 28 months and 32 months). Correlations between health parameters and age varied. Some parameters show consistent patterns with age across studies and in both sexes, others changed in one sex only and others showed no significant differences in mice of different ages. Few correlations existed among health assays, suggesting that physiological function in domains we assessed change independently in aging mice. With one exception, health parameters were not significantly associated with an increased probability of premature death. Our results show the need for more robust measures of murine health and suggest a potential disconnect between health and lifespan in mice. PMID- 27705905 TI - Adipocytes cause leukemia cell resistance to daunorubicin via oxidative stress response. AB - Adipocytes promote cancer progression and impair treatment, and have been shown to protect acute lymphoblastic leukemia (ALL) cells from chemotherapies. Here we investigate whether this protection is mediated by changes in oxidative stress. Co-culture experiments showed that adipocytes protect ALL cells from oxidative stress induced by drugs or irradiation. We demonstrated that ALL cells induce intracellular ROS and an oxidative stress response in adipocytes. This adipocyte oxidative stress response leads to the secretion of soluble factors which protect ALL cells from daunorubicin (DNR). Collectively, our investigation shows that ALL cells elicit an oxidative stress response in adipocytes, leading to adipocyte protection of ALL cells against DNR. PMID- 27705907 TI - The precision relationships between eight GWAS-identified genetic variants and breast cancer in a Chinese population. AB - Some of the new breast cancer susceptibility loci discovered in recent Genome wide association studies (GWASs) have not been confirmed in Chinese populations. To determine whether eight novel Single-Nucleotide Polymorphisms (SNPs) have associations with breast cancer risk in women from southeast China, we conducted a case-control study of 1,156 breast cancer patients and 1,256 healthy controls. We first validated that the SNPs rs12922061, rs2290203, and rs2981578 were associated with overall breast cancer risk in southeast Chinese women, with the per-allele OR of 1.209 (95%CI: 1.064-1.372), 1.176 (95%CI: 1.048-1.320), and 0.852 (95%CI: 0.759-0.956), respectively. Rs12922061 and rs2290203 even passed the threshold for Bonferroni correction (P value: 0.00625). In stratified analysis, we found another three SNPs were significantly associated within different subgroups. However, after Bonferroni correction (P value: 0.000446), there were no statistically significant was observed. In gene-environment interaction analysis, we observed gene-environment interactions played a potential role of in the risk of breast cancer. These findings provide new insight into the associations between the genetic susceptibility and fine classifications of breast cancer. Based on these results, we encourage further large series studies and functional research to confirm these finding. PMID- 27705906 TI - Cyr61-positive cancer stem-like cells enhances distal metastases of pancreatic cancer. AB - Efficient inhibition of tumor metastasis after resection of primary tumors is critical for cancer therapy. We have recently shown that Cyr61 promotes growth of pancreatic ductal adenocarcinoma (PDAC) through PI3k/Akt signaling-enhanced nuclear exclusion of p27. Here, we report that administration of adeno-associated viral vectors carrying a short-hairpin interfering RNA (shRNA) for Cyr61 via pancreatic duct significantly decreased the distal tumor metastases after resection of primary pancreatic tumor in mice. Moreover, Cyr61 depletion in PDAC cells significantly inhibited the tumor sphere formation in vitro, significantly decreased the growth of the subcutaneously transplanted tumor, and significantly decreased the incidence of tumor formation after serial adoptive transplantation into NOD/SCID mice. Finally, higher Cyr61 levels were detected in the PDAC specimens from the patients with distal tumor metastasis, compared to PDAC without metastasis at diagnosis. Together, our study suggests that suppression of Cyr61 in cancer stem cell-like cells in PDAC may inhibit tumor cell metastasis after resection of the primary tumor. PMID- 27705908 TI - An inhibitor of cholesterol absorption displays anti-myeloma activity by targeting the JAK2-STAT3 signaling pathway. AB - The activated JAK2-STAT3 signaling pathway is a high risk factor for multiple myeloma (MM), a fatal malignancy of plasma cells. In the present study, SC09, a potential inhibitor of cholesterol absorption, was identified in a STAT3-targeted drug screen. SC09 suppressed the activation of STAT3 in a time-course and concentration-dependent manner but did not affect its family members STAT1 and STAT5. SC09 inhibited STAT3 transcriptional activity and downregulated the expression of STAT3-regulated genes. Further studies showed that SC09 selectively inhibited JAK2 activation but not other kinases including c-Src, ERK, p38 and mTOR that are all associated with STAT3 activation. Moreover, SC09 obviously induced MM cell death in vitro and delayed MM tumor growth in vivo. SC09-induced MM cell death was dependent on the endogenous STAT3 status, and this effect could be attenuated by enforced expression of STAT3. All the results collectively indicated that SC09 blocks the JAK2-STAT3 signaling thus displaying anti-MM activity. Given its well tolerance and anti-MM potency, SC09 is credited for further investigation as a promising drug for MM treatment. PMID- 27705909 TI - PARP1 inhibitor olaparib (Lynparza) exerts synthetic lethal effect against ligase 4-deficient melanomas. AB - Cancer including melanoma may be ''addicted" to double strand break (DSB) repair and targeting this process could sensitize them to the lethal effect of DNA damage. PARP1 exerts an important impact on DSB repair as it binds to both single and double- strand breaks. PARP1 inhibitors might be highly effective drugs triggering synthetic lethality in patients whose tumors have germline or somatic defects in DNA repair genes. We hypothesized that PARP1-dependent synthetic lethality could be induced in melanoma cells displaying downregulation of DSB repair genes. We observed that PARP1 inhibitor olaparib sensitized melanomas with reduced expression of DNA ligase 4 (LIG4) to an alkylatimg agent dacarbazine (DTIC) treatment in vitro, while normal melanocytes remained intact. PARP1 inhibition caused accumulation of DSBs, which was associated with apoptosis in LIG4 deficient melanoma cells. Our hypothesis that olaparib is synthetic lethal with LIG4 deficiency in melanoma cells was supported by selective anti-tumor effects of olaparib used either alone or in combination with dacarbazine (DTIC) in LIG4 deficient, but not LIG4 proficient cells. In addition, olaparib combined with DTIC inhibited the growth of LIG4 deficient human melanoma xenografts. This work for the first time demonstrates the effectiveness of a combination of PARP1 inhibitor olaparib and alkylating agent DTIC for treating LIG4 deficient melanomas. In addition, analysis of the TCGA and transcriptome microarray databases revealed numerous individual melanoma samples potentially displaying specific defects in DSB repair pathways, which may predispose them to synthetic lethality triggered by PARP1 inhibitor combined with a cytotoxic drug. PMID- 27705910 TI - Indoleamine 2,3-dioxygenase regulates anti-tumor immunity in lung cancer by metabolic reprogramming of immune cells in the tumor microenvironment. AB - Indoleamine 2,3-dioxygenase (IDO) has been implicated in immune evasion by tumors. Upregulation of this tryptophan (Trp)-catabolizing enzyme, in tumor cells and myeloid-derived suppressor cells (MDSCs) within the tumor microenvironment (TME), leads to Trp depletion that impairs cytotoxic T cell responses and survival; however, exact mechanisms remain incompletely understood. We previously reported that a combination therapy of gemcitabine and a superoxide dismutase mimetic promotes anti-tumor immunity in a mouse model of lung cancer by inhibiting MDSCs, enhancing polyfunctional response of CD8+ memory T cells, and extending survival. Here, we show that combination therapy targets IDO signaling, specifically in MDSCs, tumor cells, and CD8+ T cells infiltrating the TME. Deficiency of IDO caused significant reduction in tumor burden, tumor infiltrating MDSCs, GM-CSF, MDSC survival and infiltration of programmed death receptor-1 (PD-1)-expressing CD8+ T cells compared to controls. IDO-/- MDSCs downregulated nutrient-sensing AMP-activated protein kinase (AMPK) activity, but IDO-/- CD8+ T cells showed AMPK activation associated with enhanced effector function. Our studies provide proof-of-concept for the efficacy of this combination therapy in inhibiting IDO and T cell exhaustion in a syngeneic model of lung cancer and provide mechanistic insights for IDO-dependent metabolic reprogramming of MDSCs that reduces T cell exhaustion and regulates anti-tumor immunity. PMID- 27705911 TI - Targeting SALL4 by entinostat in lung cancer. AB - The overall survival of lung cancer patients remains dismal despite the availability of targeted therapies. Oncofetal protein SALL4 is a novel cancer target. We herein report that SALL4 was aberrantly expressed in a subset of lung cancer patients with poor survival. SALL4 silencing by RNA interference or SALL4 peptide inhibitor treatment led to impaired lung cancer cell growth. Expression profiling of SALL4-knockdown cells demonstrated that both the EGFR and IGF1R signaling pathways were affected. Connectivity Map analysis revealed the HDAC inhibitor entinostat as a potential drug in treating SALL4-expressing cancers, and this was confirmed in 17 lung cancer cell lines. In summary, we report for the first time that entinostat can target SALL4-positive lung cancer. This lays the foundation for future clinical studies evaluating the therapeutic efficacy of entinostat in SALL4-positive lung cancer patients. PMID- 27705912 TI - TACC3 overexpression in cholangiocarcinoma correlates with poor prognosis and is a potential anti-cancer molecular drug target for HDAC inhibitors. AB - Histone deacetylases (HDACs) have been implicated in multiple malignant tumors, and HDAC inhibitors (HDACIs) exert anti-cancer effects. However, the expression of HDACs and the anti-tumor mechanism of HDACIs in cholangiocarcinoma (CCA) have not yet been elucidated. In this study, we found that expression of HDACs 2, 3, and 8 were up-regulated in CCA tissues and those patients with high expression of HDAC2 and/or HDAC3 had a worse prognosis. In CCA cells, two HDACIs, trichostatin (TSA) and vorinostat (SAHA), suppressed proliferation and induced apoptosis and G2/M cycle arrest. Microarray analysis revealed that TACC3 mRNA was down regulated in CCA cells treated with TSA. TACC3 was highly expressed in CCA tissues and predicted a poor prognosis in CCA patients. TACC3 knockdown induced G2/M cycle arrest and suppressed the invasion, metastasis, and proliferation of CCA cells, both in vitro and in vivo. TACC3 overexpression reversed the effects of its knockdown. These findings suggest TACC3 may be a useful prognostic biomarker for CCA and is a potential therapeutic target for HDACIs. PMID- 27705913 TI - Epithelioid peritoneal mesothelioma: a hybrid phenotype within a mesenchymal epithelial/epithelial-mesenchymal transition framework. AB - The aim of this study was to reconsider the biological characteristics of epithelioid malignant peritoneal mesothelioma (E-MpM) in the light of new concepts about epithelial mesenchymal transition and mesenchymal epithelial reverse transition (EMT/MErT) and the role of epigenetic reprogramming in this context. To this end we profiled surgical specimens and derived cells cultures by a number of complementary approaches i.e. immunohistochemistry, immunofluorescence, in situ hybridization, biochemistry, pluripotent stem cell arrays, treatments with cytokines, growth factors and specific inhibitors.The analyses of the surgical specimens showed that i) EZH2 is expressed throughout the spectrum of MpM, ii) that E-MpM (including the high-grade undifferentiated form) are characterised by c-MYC and miRNA 17-5p expression, and iii) that progression to sarcomatoid MpM is dictated by EMT regulators. They also showed that E-MpM expressed c-MET and are enriched in E- and P-cadherins- and VEGFR2 expressing CSCs, thus strongly supporting a role for MErT reprogramming in endowing E-MpM tumour cells with stemness and plasticity, and hence with a drug resistant phenotype. The cell culture-based experiments confirmed the stemness traits and plasticity of E-MpM, and support the view that EZH2 is a druggable target in this tumor. PMID- 27705914 TI - Extrachromosomal HPV-16 LCR transcriptional activation by HDACi opposed by cellular differentiation and DNA integration. AB - Histone deacetylase inhibitors (HDACi) have been shown to render HPV-carrying cells susceptible to intrinsic and extrinsic apoptotic signals. As such, these epigenetic drugs have entered clinical trials in the effort to treat cervical cancer. Here, we studied the effect of common HDACi, with an emphasis on Trichostatin A (TSA), on the transcriptional activity of the HPV-16 Long Control Region (LCR) in order to better understand the impact of these agents in the context of the HPV life cycle and infection. HDACi strongly induced transcription of the firefly luciferase reporter gene under the control of the HPV-16 LCR in a variety of cell lines. In the HaCaT keratinocyte cell line undergoing differentiation induced by TSA, we observed a reduction in LCR-controlled transcription. Three major AP-1 binding sites in the HPV-16 LCR are involved in the regulation by TSA. However, whatever the status of differentiation of the HaCaT cells, TSA induced integration of extra-chromosomal transfected DNA into the cellular genome. Although these data suggest caution using HDACi in the treatment of HR HPV infection, further in vivo studies are necessary to better assess the risk. PMID- 27705915 TI - LKB1 is a DNA damage response protein that regulates cellular sensitivity to PARP inhibitors. AB - Liver kinase B1 (LKB1) functions as a tumor suppressor encoded by STK11, a gene that mutated in Peutz-Jeghers syndrome and in sporadic cancers. Previous studies showed that LKB1 participates in IR- and ROS-induced DNA damage response (DDR). However, the impact of LKB1 mutations on targeted cancer therapy remains unknown. Herein, we demonstrated that LKB1 formed DNA damage-induced nuclear foci and co localized with ataxia telangiectasia mutated kinase (ATM), gamma-H2AX, and breast cancer susceptibility 1 (BRCA1). ATM mediated LKB1 phosphorylation at Thr 363 following the exposure of cells to ionizing radiation (IR). LKB1 interacted with BRCA1, a downstream effector in DDR that is recruited to sites of DNA damage and functions directly in homologous recombination (HR) DNA repair. LKB1 deficient cells exhibited delayed DNA repair due to insufficient HR. Notably, LKB1 deficiency sensitized cells to poly (ADP-ribose) polymerase (PARP) inhibitors. Thus, we have demonstrated a novel function of LKB1 in DNA damage response. Cancer cells lacking LKB1 are more susceptible to DNA damage-based therapy and, in particular, to drugs that further impair DNA repair, such as PARP inhibitors. PMID- 27705916 TI - Asporin enhances colorectal cancer metastasis through activating the EGFR/src/cortactin signaling pathway. AB - Asporin has been implicated as an oncogene in various types of human cancers; however, the roles of asporin in the development and progression of colorectal cancer (CRC) have not yet been determined. With clinical samples, we found that asporin was highly expressed in CRC tissues compared to adjacent normal tissues and the asporin expression levels were significantly associated with lymph node metastasis status and TNM stage of the patients. Through knockdown of asporin in CRC cell lines RKO and SW620 or overexpression of asporin in cell lines HT-29 and LoVo, we found that asporin could enhance wound healing, migration and invasion abilities of the CRC cells. Further more, with the human umbilical vein endothelial cells (HUVECs) tube formation assays and the xenograft model, we found that asporin promoted the tumor growth through stimulating the VEGF signaling pathway. The portal vein injection models suggested that asporin overexpression stimulated the liver metastasis of HT29 cell line, while asporin knockdown inhibited the liver metastasis of RKO cell line. In addition, asporin was found to augment the phosphorylation of EGFR/src/cortactin signaling pathway, which might be contributed to the biological functions of asporin in CRC metastasis. These results suggested that asporin promoted the tumor growth and metastasis of CRC, and it could be a potential therapeutic target for CRC patients in future. PMID- 27705917 TI - Reciprocal regulation of the cholinic phenotype and epithelial-mesenchymal transition in glioblastoma cells. AB - Glioblastoma (GBM) is the most malignant brain tumor with very limited therapeutic options. Standard multimodal treatments, including surgical resection and combined radio-chemotherapy do not target the most aggressive subtype of glioma cells, brain tumor stem cells (BTSCs). BTSCs are thought to be responsible for tumor initiation, progression, and relapse. Furthermore, they have been associated with the expression of mesenchymal features as a result of epithelial mesenchymal transition (EMT) thereby inducing tumor dissemination and chemo resistance. Using high resolution proton nuclear magnetic resonance spectroscopy (1H NMR) on GBM cell cultures we provide evidence that the expression of well known EMT activators of the ZEB, TWIST and SNAI families and EMT target genes N cadherin and VIMENTIN is associated with aberrant choline metabolism. The cholinic phenotype is characterized by high intracellular levels of phosphocholine and total choline derivatives and was associated with malignancy in various cancers. Both genetic and pharmacological inhibition of the cardinal choline metabolism regulator choline kinase alpha (CHKalpha) significantly reduces the cell viability, invasiveness, clonogenicity, and expression of EMT associated genes in GBM cells. Moreover, in some cell lines synergetic cytotoxic effects were observed when combining the standard of care chemotherapeutic temozolomide with the CHKalpha inhibitor V-11-0711. Taken together, specific inhibition of the enzymatic activity of CHKalpha is a powerful strategy to suppress EMT which opens the possibility to target chemo-resistant BTSCs through impairing their mesenchymal transdifferentiation. Moreover, the newly identified EMT-oncometabolic network may be helpful to monitor the invasive properties of glioblastomas and the success of anti-EMT therapy. PMID- 27705919 TI - Exploring timing activation of functional pathway based on differential co expression analysis in preimplantation embryogenesis. AB - Recent genome-wide omics studies have confirmed the early embryogenesis strictly dependent on the rigorous spatiotemporal activation and multilevel regulation. However, the full effect of functional pathway was not considered. To obtain complete understanding of the gene activation during early development, we performed systematic comparisons based on differential co-expression analysis for bovine preimplantation embryo development (PED). The results confirmed that the functional pathways actively transcribes as early as the 2-cell and 4-cell waves, which Basal transcription factor, Endocytosis and Spliceosome pathway can represent first signs of embryonic activity. Endocytosis act as one of master activators for uncovering a series of successive waves of maternal pioneer signal regulator with the help of Spliceosome complex. Furthermore, the results showed that pattern recognition receptors began to perform its essential function at 4 cell stage, which might be needed to coordinate the later major activation. And finally, our work presented a probable dynamic landscape of key functional pathways for embryogenesis. A clearer understanding of early embryo development will be helpful for Assisted Reproductive Technology (ART) and Regenerative Medicine (RM). PMID- 27705918 TI - MicroRNA-382-5p aggravates breast cancer progression by regulating the RERG/Ras/ERK signaling axis. AB - Aberrant activation of the Ras/ERK pathway mediates breast cancer initiation and aggressiveness. Therefore, it is important to identify miRNAs that modulate the Ras/ERK pathway during breast carcinogenesis and progression. The Ras GTPase superfamily member RERG (Ras-related and estrogen-regulated growth inhibitor) acts as a tumor suppressor to reduce breast cancer cell proliferation and tumor formation and has been suggested to have a regulatory role in the Ras/ERK pathway. In this study, we found that RERG exerted its tumor suppressor role by attenuating the activation of Ras/ERK signaling effectors. Furthermore, we found that miR-382-5p directly targets and represses RERG to attenuate the inhibitory effects of RERG on the oncogenic Ras/ERK pathway. Thereby, miR-382-5p promoted breast cancer cell viability, clonogenicity, survival, migration, invasion and in vivo tumorigenesis/metastasis. In clinical interpretation, miR-382-5p expression was negatively correlated with RERG expression, and it also significantly functioned as an independent oncomiR for the higher incidence and poorer prognosis of breast cancer. This novel connection highlights new diagnostic and prognostic roles for miR-382-5p and RERG in breast cancer. PMID- 27705920 TI - Integrative analysis of protein-coding and non-coding RNAs identifies clinically relevant subtypes of clear cell renal cell carcinoma. AB - Protein-coding genes and non-coding RNAs cooperate mutually in cells. Integrative analysis of protein-coding and non-coding RNAs may facilitate characterizing tumor heterogeneity. We introduced integrated consensus clustering (ICC) method to integrate mRNA, miRNA and lncRNA expression profiles of 431 primary clear cell renal cell carcinomas (ccRCCs). We identified one RCC subgroup easily misdiagnosed as ccRCC in clinic and four robust ccRCC subtypes associated with distinct clinicopathologic and molecular features. In subtype R1, AMPK signaling pathway is significantly upregulated, which may improve the oncologic-metabolic shift and partially account for its best prognosis. Subtype R2 has more chromosomal abnormities, higher expression of cell cycle genes and less expression of genes in various metabolism pathways, which may explain its more aggressive characteristic and the worst prognosis. Moreover, much more miRNAs and lncRNAs are significantly upregulated in R2 and R4 respectively, suggesting more important roles of miRNAs in R2 and lncRNAs in R4. Triple-color co-expression network analysis identified 28 differentially expressed modules, indicating the importance of cooperative regulation of mRNAs, miRNAs and lncRNAs in ccRCC. This study establishes an integrated transcriptomic classification which may contribute to understanding the heterogeneity and implicating the treatment of ccRCC. PMID- 27705921 TI - miRNAs in acute myeloid leukemia. AB - MicroRNAs (miRNAs) are small, non-coding RNAs found throughout the eukaryotes that control the expression of a number of genes involved in commitment and differentiation of hematopoietic stem cells and tumorigenesis. Widespread dysregulation of miRNAs have been found in hematological malignancies, including human acute myeloid leukemia (AML). A comprehensive understanding of the role of miRNAs within the complex regulatory networks that are disrupted in malignant AML cells is a prerequisite for the development of therapeutic strategies employing miRNA modulators. Herein, we review the roles of emerging miRNAs and the miRNAs regulatory networks in AML pathogenesis, prognosis, and miRNA-directed therapies. PMID- 27705922 TI - Umbilical cord-derived mesenchymal stem cells reversed the suppressive deficiency of T regulatory cells from peripheral blood of patients with multiple sclerosis in a co-culture - a preliminary study. AB - The immunoregulatory function of T regulatory cells (Tregs) is impaired in multiple sclerosis (MS). Recent studies have shown that umbilical cord-derived mesenchymal stem cells (UC-MSCs) exert regulatory effect on the functions of immune cells. Thus, we investigated whether UC-MSCs could improve the impaired function of Tregs from MS patients. Co-cultures of UC-MSCs with PBMCs of MS patients were performed for 3 days. Flow cytometry was used to determine the frequency of Tregs. A cell proliferation assay was used to evaluate the suppressive capacity of Tregs. ELISA was conducted for cytokine analysis in the co-cultures. Our results showed that UC-MSCs significantly increased the frequency of CD4+CD25+CD127low/- Tregs in resting CD4+ T cells (p<0.01) from MS, accompanied by the significantly augmented production of cytokine prostaglandin E2, transforming growth factor (-beta1, and interleukin-10, along with a reduced interferon-gamma production in these co-cultures (p<0.05 - 0.01). More importantly, UC-MSC-primed Tregs of MS patients significantly inhibited the proliferation of PHA-stimulated autologous and allogeneic CD4+CD25- T effector cells (Teffs) from MS patients and healthy individuals compared to non-UC-MSC primed (naive) Tregs from the same MS patients (p<0.01). Furthermore, no remarkable differences in suppressing the proliferation of PHA-stimulated CD4+CD25- Teffs was observed in UC-MSC-primed Tregs from MS patients and naive Tregs from healthy subjects. The impaired suppressive function of Tregs from MS can be completely reversed in a co-culture by UC-MSC modulation. This report is the first to demonstrate that functional defects of Tregs in MS can be repaired in vitro using a simple UC-MSC priming approach. PMID- 27705924 TI - A mixed analysis comparing nine minimally invasive surgeries for unresectable hepatocellular carcinoma patients. AB - Hepatocellular carcinoma (HCC) is usually managed by the transcatheter arterial chemoembolization (TACE). However, this technique has been challenged since severe complications have been observed in clinical practices. As a result, clinicians have started to seek other minimally invasive surgeries with equivalent efficacy. The corresponding surgeries were assessed by the five outcomes: complete response (CR), partial response (PR), stable disease (SD), progression disease (PD) and objective response rate (ORR). Direct meta-analysis and network meta-analysis were performed and the results were represented by odds ratios (OR), 95% confidence and credential intervals. Furthermore, the value of surface under the cumulative ranking curve (SUCRA)was calculated to provide corresponding rankings.Seventeen studies were incorporated into the network meta analysis which indicated that TACE + external-beam radiation therapy (EBRT) and drug-eluting beads (DEB) were better than TACE at controllingPD. TACE + EBRT demonstrated their advantages compared to TARE-90Y.However, network meta-analysis comparison showed no significant difference between the corresponding eight treatments with respect to CR, PR, SD and ORR. Moreover, the SUCRA suggested that TACE+EBRT were better than other treatments at treating unresectableHCC.Based on the present results of this network meta-analysis, TACE + EBRT was more effective than the other seven minimally invasive surgeries and therefore it is considered as the optimal treatment for HCC. PMID- 27705923 TI - Mucins and associated O-glycans based immunoprofile for stratification of colorectal polyps: clinical implication for improved colon surveillance. AB - Sessile serrated adenoma/polyps (SSA/P) are premalignant lesions of colorectal cancer that are difficult to distinguish histologically from hyperplastic polyps (HP) of minimal to no malignant potential. Specific markers for differentiating SSA/P from HP can aid clinicians for optimizing colon surveillance intervals. The present study investigates the potential of mucins and associated O-glycans to distinguish SSA/P from HP. Expression of colonic mucins (MUC1, MUC4, MUC17, MUC2, and MUC5AC) and O-glycans [Sialyl LewisA (CA19-9) and Tn/Sialyl-Tn on MUC1] were analyzed in HP (n=33), SSA/P (n=39), and tubular adenoma (TA) (n=36) samples by immunohistochemistry. A significantly reduced expression of MUC4 (p=0.0066), elevated expression of MUC17 (p=0.0002), and MUC5AC (p<0.0001) was observed in SSA/P cases in comparison to HP cases. Interestingly, significantly higher number of SSA/P cases (p<0.0001) exhibited MUC5AC expression in the goblet cells as well as filled the crypt lumen compared to only goblet cells in majority of the HP cases. Improved diagnostic potential was revealed by multivariate logistic regression analysis where combinatorial panel of MUC5AC/MUC17 discriminated SSA/P from HP (SN/SP=85/82%). Finally, the decision tree model based marker panel (CA19 9/MUC17/MUC5AC) predicted HP, SSA/P and TA with SN/SP of 58%/95%, 79%/90% and 97%/83%, respectively. Overall, the mucin and associated O-glycan based panel defined in the present study could aid in discriminating SSA/P from HP to devise better colon surveillance strategies. PMID- 27705925 TI - Mutational load of the mitochondrial genome predicts pathological features and biochemical recurrence in prostate cancer. AB - Prostate cancer management is complicated by extreme disease heterogeneity, which is further limited by availability of prognostic biomarkers. Recognition of prostate cancer as a genetic disease has prompted a focus on the nuclear genome for biomarker discovery, with little attention given to the mitochondrial genome. While it is evident that mitochondrial DNA (mtDNA) mutations are acquired during prostate tumorigenesis, no study has evaluated the prognostic value of mtDNA variation. Here we used next-generation sequencing to interrogate the mitochondrial genomes from prostate tissue biopsies and matched blood of 115 men having undergone a radical prostatectomy for which there was a mean of 107 months clinical follow-up. We identified 74 unique prostate cancer specific somatic mtDNA variants in 50 patients, providing significant expansion to the growing catalog of prostate cancer mtDNA mutations. While no single variant or variant cluster showed recurrence across multiple patients, we observe a significant positive correlation between the total burden of acquired mtDNA variation and elevated Gleason Score at diagnosis and biochemical relapse. We add to accumulating evidence that total acquired genomic burden, rather than specific mtDNA mutations, has diagnostic value. This is the first study to demonstrate the prognostic potential of mtDNA mutational burden in prostate cancer. PMID- 27705926 TI - Caveolin-1 controls mitochondrial function through regulation of m-AAA mitochondrial protease. AB - Mitochondrial proteases ensure mitochondrial integrity and function after oxidative stress by providing mitochondrial protein quality control. However, the molecular mechanisms that regulate this basic biological function in eukaryotic cells remain largely unknown. Caveolin-1 is a scaffolding protein involved in signal transduction. We find that AFG3L2, a m-AAA type of mitochondrial protease, is a novel caveolin-1-interacting protein in vitro. We show that oxidative stress promotes the translocation of both caveolin-1 and AFG3L2 to mitochondria, enhances the interaction of caveolin-1 with AFG3L2 in mitochondria and stimulates mitochondrial protease activity in wild-type fibroblasts. Localization of AFG3L2 to mitochondria after oxidative stress is inhibited in fibroblasts lacking caveolin-1, which results in impaired mitochondrial protein quality control, an oxidative phosphorylation to aerobic glycolysis switch and reduced ATP production. Mechanistically, we demonstrate that a lack of caveolin-1 does not alter either mitochondrial number or morphology but leads to the cytoplasmic and proteasome-dependent degradation of complexes I, III, IV and V upon oxidant stimulation. Restoration of mitochondrial respiratory chain complexes in caveolin 1 null fibroblasts reverts the enhanced glycolysis observed in these cells. Expression of a mutant form of AFG3L2, which has reduced affinity for caveolin-1, fails to localize to mitochondria and promotes degradation of complex IV after oxidative stress. Thus, caveolin-1 maintains mitochondrial integrity and function when cells are challenged with free radicals by promoting the mitochondrial localization of m-AAA protease and its quality control functions. PMID- 27705927 TI - Heparan sulfate hexasaccharide selectively inhibits cancer stem cells self renewal by activating p38 MAP kinase. AB - Heparan sulfate (HS) plays a role in the majority of essential hallmarks of cancer, yet its ability to modulate self-renewal, especially of cancer stem cells (CSCs), remains unknown. We have discovered that a non-anticoagulant HS hexasaccharide (HS06) sequence, but not other shorter or longer sequences, selectively inhibited CSC self-renewal and induced apoptosis in colorectal, pancreatic, and breast CSCs suggesting a very general phenomenon. HS06 inhibition of CSCs relied upon early and sustained activation of p38alpha/beta mitogen activated protein kinase (MAPK) but not other MAPKs family members i.e. ERK and JNK. In contrast, polymeric HS induced exactly opposite changes in MAPK activation and failed to inhibit CSCs. In fact, TCF4 signaling, a critical regulator of CSC self-renewal, was inhibited by HS06 in a p38 activation dependent fashion. In conclusion, HS06 selectively inhibits CSCs self-renewal by causing isoform specific activation of p38MAPK to inhibit TCF4 signaling. These observations on chain length-induced specificity carry major mechanistic implications with regard to HS in cancer biology, while also presenting a novel paradigm for developing novel anti-CSC hexasaccharides that prevent cancer relapse.Heparan sulfate (HS) of specific length, i.e., hexasaccharide (HS06), but not longer or shorter sequences, selectively inhibit cancer stem cells (CSCs) through isoform specific activation of p38 mitogen-activated protein kinase. These findings will have major implication for developing chemical probes to decipher complex signaling events that govern cancer stem cells. Additionally, there are direct implications for designing glycosaminoglycan based cancer therapies to selectively target CSCs that escape killing by traditional chemotherapy threatening cancer relapse. PMID- 27705928 TI - Unraveling the expression of the oncogene YAP1, a Wnt/beta-catenin target, in adrenocortical tumors and its association with poor outcome in pediatric patients. AB - BACKGROUND: Overexpression of the oncogene yes-associated-protein-1 (YAP1) is associated with increased cell proliferation in human cancers. YAP1 is a potential target of the Wnt/beta-catenin pathway, which plays an important role in adrenocortical tumors (ACT). The role of YAP1 in adrenocortical tumorigenesis has not been assessed. AIMS: To evaluate YAP1 expression in normal adrenals and pediatric ACT and its association with disease outcome. To investigate the interaction between YAP1 and the Wnt/beta-catenin pathway in adrenocortical cells. RESULTS: Strong YAP1 staining was present in fetal adrenals and pediatric ACT but weak in postnatal adrenals. In pediatric ACT, YAP1 mRNA overexpression was associated with death, recurrent/metastatic disease and lower overall survival. The inhibition of the Wnt/beta-catenin pathway increased YAP1 mRNA expression. siYAP1 increased CTNNB1/beta-catenin expression and nuclear staining regardless of DLV2, moreover, it decreased cell growth and impaired cell migration. MATERIALS AND METHODS: We assessed in 42 pediatric ACT samples the YAP1 protein expression by immunohistochemistry and mRNA expression by RT-qPCR and analyzed their association with outcome. As controls, we resort 32 fetal and postnatal normal adrenals for IHC and 10 normal adrenal cortices for RT-qPCR. The interaction between YAP1 and the Wnt/beta-catenin pathway was assessed in NCI H295 adrenocortical cells by inhibiting the TCF/beta-catenin complex and by knocking down YAP1. CONCLUSION: YAP1 overexpression is a marker of poor prognosis for pediatric patients with ACT. In adrenocortical cells, there is a close crosstalk between YAP1 and Wnt/beta-catenin. These data open the possibility of future molecular therapies targeting Hippo/YAP1 signaling to treat advanced ACT. PMID- 27705930 TI - Pyroptosis is involved in the pathogenesis of human hepatocellular carcinoma. AB - Pyroptosis is a caspase-1 dependent programmed cell death, which is involved in the pathologic process of several kinds of cancers. Loss of caspase-1 gene expression has been observed in prostate and gastric cancers. However, the role of pyroptosis in human hepatocellular carcinoma (HCC) remains largely unknown. The aim of this study was to investigate the involvement of pyroptosis in the pathogenesis of HCC. Our study showed that pyroptosis was inhibited in HCC tissues and cells. Administration of berberine inhibited the viability, migration and invasion capacity of HepG2 cells through the induction of pyroptosis both in vitro and in vivo, which was attenuated by caspase-1 inhibitor Ac-YVAD-CMK. Conclusively, pyroptosis is involved in the pathogenesis of HCC, and may be a new neoplastic target for the treatment of HCC. PMID- 27705929 TI - A 5-day cytoreductive chemotherapy followed by haplo-identical hsct (FA5-BUCY) as a tumor-ablative regimen improved the survival of patients with advanced hematological malignancies. AB - Haplo-HSCT has been used when HLA-matched siblings are not available. Conditioning regimens aim to reduce tumor burden prior to HSCT and provide sufficient immunoablation. We report the outcome of haplo-HSCT in 63 consecutive patients from 2/2013 to 12/2015 (19 females/44 males) with high-risk or relapsed/refractory hematological malignancies (n=29-AML; 8-sAML; 19-ALL; 5 advanced-MDS; 2-CML-BC). Median age was 20 years (range: 1.1-49). Twenty-one patients achieved remission prior to transplant, while 42 did not. Patients received FA5-BUCY, i.e., 5-day salvage chemotherapy (Fludarabine/Ara-C) and conditioning (Busulfan/Cyclophosphamide). GvHD prophylaxis included ATG, CsA, MMF and short-term MTX. All patients received stem cells from bone marrow and peripheral blood, and achieved successful engraftment, except two who died before. With a median follow-up of 269 days (120-1081), 42/63 patients are still alive and disease-free. Two-year OS and RFS were similar in patients not in remission and in those in complete remission (61.3% vs 56.3%, p=0.88; 58.3% vs 56.3%, p=0.991). Non-relapse mortality and relapse incidence were 22.2% and 11.1%, respectively. Severe acute-GvHD occurred in 4/63 patients. Transplant related mortality was low at day+100 (17.5%) and for the entire study period (20.6%). Unexpectedly, few patients experienced mild-to-moderate toxicity, and main causes of death were infection and GvHD. BM blast counts, age, and donor recipient gender-pairs did not affect the outcome. Less chemotherapy cycles prior to HSCT might result in more favorable outcome. Thus, haplo-HSCT with FA5-BUCY appears promising for advanced disease, especially when TBI and amsacrine, used for FLAMSA, are not available and in pediatric patients for whom TBI is not recommended. PMID- 27705931 TI - miR128-1 inhibits the growth of glioblastoma multiforme and glioma stem-like cells via targeting BMI1 and E2F3. AB - MicroRNA128-1 (miR128-1), as a brain-specific miRNA, is downregulated in glioblastoma multiforme (GBM) and closely associated with the progression of GBM. However, the underlying molecular mechanism of the downregulation and its role in the regulation of tumorigenesis and anticancer drug resistance in GBM remains largely unknown. In the current study,we found that miR128-1 was downregulated in GBM and glioma stem-like cells (GSCs). Intriguingly, treatment with the DNA methylation inhibitors 5-Aza-CdR (Aza) and 4-phenylbutyric acid (PBA) resulted in miR128-1 upregulation in both GBM cells and GSCs. Either forced expression of miR128-1 or Aza/PBA treatment inhibited tumor cell proliferation, migration and invasion in vitro. Moreover, overexpression of miR128-1 inhibited the growth of transplant tumor in vivo. BMI1 and E2F3 were found to be direct targets of miR128 1 and downregulated by miR128-1 in vitro and in vivo. Our results revealed a mechanism of methylation that controls miR128-1 expression in GBM cells and GSCs and indicate miR128-1 could function as a tumor suppressor in GBM by negatively regulating tumor cell proliferation, invasion and self-renewal through direct targeting BMI1 and E2F3. Our findings suggest that DNA methylation inhibitors are potential agents for GBM treatment by upregulating miR-128-1. PMID- 27705932 TI - KRAS mutations in blood circulating cell-free DNA: a pancreatic cancer case control. AB - The utility of KRAS mutations in plasma circulating cell-free DNA (cfDNA) samples as non-invasive biomarkers for the detection of pancreatic cancer has never been evaluated in a large case-control series. We applied a KRAS amplicon-based deep sequencing strategy combined with analytical pipeline specifically designed for the detection of low-abundance mutations to screen plasma samples of 437 pancreatic cancer cases, 141 chronic pancreatitis subjects, and 394 healthy controls. We detected mutations in 21.1% (N=92) of cases, of whom 82 (89.1%) carried at least one mutation at hotspot codons 12, 13 or 61, with mutant allelic fractions from 0.08% to 79%. Advanced stages were associated with an increased proportion of detection, with KRAS cfDNA mutations detected in 10.3%, 17,5% and 33.3% of cases with local, regional and systemic stages, respectively. We also detected KRAS cfDNA mutations in 3.7% (N=14) of healthy controls and in 4.3% (N=6) of subjects with chronic pancreatitis, but at significantly lower allelic fractions than in cases. Combining cfDNA KRAS mutations and CA19-9 plasma levels on a limited set of case-control samples did not improve the overall performance of the biomarkers as compared to CA19-9 alone. Whether the limited sensitivity and specificity observed in our series of KRAS mutations in plasma cfDNA as biomarkers for pancreatic cancer detection are attributable to methodological limitations or to the biology of cfDNA should be further assessed in large case control series. PMID- 27705933 TI - Definition and characterization of novel HLA-*A02-restricted CD8+ T cell epitopes derived from JCV polyomavirus with clinical relevance. AB - Human JC and BK polyomaviruses (JCV/BKV) can establish a latent infection without any clinical symptoms in healthy individuals. In immunocompromised hosts infection or reactivation of JCV and BKV can cause lethal progressive multifocal leukoencephalopathy (PML) and hemorrhagic cystitis, respectively. Vaccination with JCV/BKV derived antigen epitope peptides or adoptive transfer of virus specific T cells would constitute an elegant approach to clear virus-infected cells. Furthermore, donor leukocyte infusion (DLI) is another therapeutic approach which could be helpful for patients with JCV/BKV infections.So far, only few immunodominant T cell epitopes of JCV and BKV have been described and therefore is a fervent need for the definition of novel epitopes. In this study, we identified novel T cell epitopes by screening libraries of overlapping peptides derived from the major capsid protein VP1 of JCV. Virus like particles (VLPs) were used to confirm naturally processing. Two human leucocyte antigen (HLA)-A*02-restricted epitopes were characterized by fine mapping with overlapping peptides and nonamer peptide sequences were identified. Cytokine release profile of the epitope-specific T cells was analyzed by enzyme-linked immunospot (ELISPOT) assays and by flow cytometry. We demonstrated that T cell responses were of polyfunctional nature with the potential of epitope-specific killing and cross-reactivity between JCV and BKV. These novel epitopes might constitute a new potential tool to design effective diagnostic and therapeutic approaches against both polyomaviruses. PMID- 27705934 TI - Notch1 promotes vasculogenic mimicry in hepatocellular carcinoma by inducing EMT signaling. AB - Hypervascularity is one of the main characteristics of hepatocellular carcinoma (HCC). However, the mechanisms of angiogenesis in HCC remain controversial. In this study, we investigate the role of Notch1 in angiogenesis of HCC. We found that Notch1 expression was correlated with formation of vasculogenic mimicry (VM) and expression of biomarkers of epithelial-to-mesenchymal transition (EMT) in the tumor specimens. Two HCC cell lines, HepG2 and MHCC97-H, with low and high Notch1 expression, respectively, were used to study the mechanism of VM formation both in vitro and in vivo. It was found that MHCC97-H cells, but not HepG2 cells form VM when they grow on matrigel in vitro. HepG2 cells gained the power of forming VM when they were overexpressed with Notch1, while knockdown Notch1 expression in MHCC97-H cells led to the loss of VM forming ability of the cells. Similar results were found in in vivo study. High expression of Notch1 in HepG2 promoted xenograft growth in nude mice, with abundant VM formation in the tumor samples. Moreover, we observed Notch1 was associated with the EMT and malignant behavior of hepatocellular carcinoma by analyzing clinical specimens, models for in vitro and in vivo experiments. HepG2 presented EMT phenomenon when induced by TGF beta1, accompanied by Notch1 activation while MHCC97-H with knockdown of Notch1 lost the responsiveness to TGF-beta1 induction. Our results suggest that Notch1 promotes HCC progression through activating EMT pathway and forming VM. Our results will guide targeting Notch1 in new drug development. PMID- 27705935 TI - Circulating microRNA124-3p, microRNA9-3p and microRNA196b-5p may be potential signatures for differential diagnosis of thyroid nodules. AB - It is important to develop an effective auxiliary approach to distinguish papillary thyroid carcinoma (PTC) from benign nodules because a considerable proportion cannot be identified by fine-needle aspiration cytology at present, resulting in unnecessary thyroidectomy. Circulating miRNAs are potential biomarkers for differential diagnosis of tumors. We aimed to investigate the dysregulation of circulating miRNAs in PTC and evaluate the diagnostic value for differentiation of PTC from benign nodules. We first assessed the expression of miRNAs in patients with PTC, patients with benign nodules and healthy controls using a miRCURY LNA Array (n = 3 for each group). Expression of circulating miR 124-3p, miR-9-3p and miR-5691 was significantly up-regulated, while miR-4701 and miR-196b-5p were down-regulated in PTC patients. The dysregulation of miR-124-3p, miR-9-3p, miR-4701 and miR-196b-5p was further validated by qRT-PCR in fifty participants from each group. The expression of circulating miR-124-3p and miR-9 3p was significantly up-regulated in PTC patients. Both miR-124-3p and miR-9-3p could distinguish PTC from benign nodules with high sensitivity and specificity. There were no significant differences in the expression of circulating miR-4701 and miR-196b-5p between PTC patients and healthy controls. Nevertheless, patients with benign nodules showed a higher level of miR-196b-5p compared with that of PTC patients and healthy controls. ROC analysis indicated that miR-196b-5p had a good diagnostic value for differentiation of benign nodules from PTC. Our study suggested that miR-124-3p, miR-9-3p and miR-196b-5p may be potential signatures for differential diagnosis of thyroid nodules in eastern coastal areas of China. PMID- 27705936 TI - Meta-analysis of gene expression and integrin-associated signaling pathways in papillary renal cell carcinoma subtypes. AB - Papillary renal cell carcinoma (PRCC) is the second most common renal cell carcinoma (RCC) that can be further subdivided into type 1 (PRCC1) and type 2 (PRCC2) RCCs based on histological and genetic features. PRCC2 is often more aggressive than PRCC1. While integrin-associated protein complexes mediate tumorigenesis and metastases in many types of cancers it is not known whether integrin-mediated signaling impacts PRCC and differs between PRCC1 and PRCC2. In this study, we combined the analysis of five PRCC gene expression datasets derived from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) by using integrative bioinformatics pipelines. We found 1475 differentially expressed genes among which 37 genes were associated with integrin pathways. In comparison with PRCC1, PRCC2 cases showed upregulated expression of alpha5 integrin (ITGA5) whereas the expression of alpha6- (ITGA6) and beta8-integrins (ITGB8) was downregulated. Because PRCC2 occurs more frequently in men, the meta analysis was extended to explore the gender effects. This analysis revealed 8 genes but none of them was related to integrin pathways suggesting that other mechanisms than integrin-mediated signaling underlie the observed gender differences in the pathogenicity of PRCC2. PMID- 27705937 TI - Metformin potentiates anti-tumor effect of resveratrol on pancreatic cancer by down-regulation of VEGF-B signaling pathway. AB - Our previous study showed that resveratrol (RSV) exhibited not only anti-tumor effect, but also had potential tumor promotion effect on pancreatic cancer (Paca) cells through up-regulation of VEGF-B. We determined whether metformin (MET) could potentiate the anti-tumor effect of RSV on PaCa in this study. Combination of RSV (100 MUmol/l) and MET (20 mmol/l) significantly inhibited tumor growth and increased apoptosis of human PaCa in comparison with RSV or MET alone treatment in PaCa cell lines (Miapaca-2, Panc-1 and Capan-2). Combination of RSV (60 mg/kg, gavage) and MET (250 mg/kg, i.p.) significantly inhibited tumor growth in PaCa bearing nude mice (subcutaneous injection of 5 * 106 Miapaca-2 cells) in comparison with RSV or MET alone treatment on day 40. Combination treatment significantly decreased VEGF-B expression and inhibited activity of GSK-3beta when compared to the RSV alone treatment. Up-regulated expressions of Bax, cleaved caspase-3 and down-regulated expression of Bcl-2 were observed in RSV+ MET group in comparison with RSV group either in vitro or in vivo. Inhibition of VEGF-B by VEGF-B small interfering RNA (siRNA) mimicked the effects of MET on PaCa cells. These results suggested that MET, a potential pharmacological inhibitor of VEGF-B signaling pathway, potentiated the anti-tumor effect of RSV on PaCa, and combination of MET and RSV would be a promising modality for clinical PaCa therapy. PMID- 27705938 TI - Inhibition of autophagy inhibits the conversion of cardiac fibroblasts to cardiac myofibroblasts. AB - The incidence of heart failure with concomitant cardiac fibrosis is very high in developed countries. Fibroblast activation in heart is causal to cardiac fibrosis as they convert to hypersynthetic cardiac myofibroblasts. There is no known treatment for cardiac fibrosis. Myofibroblasts contribute to the inappropriate remodeling of the myocardial interstitium, which leads to reduced cardiac function and ultimately heart failure. Elevated levels of autophagy have been linked to stress-induced ventricular remodeling and other cardiac diseases. Previously, we had shown that TGF-beta1 treatment of human atrial fibroblasts both induced autophagy and enhanced the fibrogenic response supporting a linkage between the myofibroblast phenotype and autophagy. We now demonstrate that with in vitro culture of primary rat cardiac fibroblasts, inhibition of autophagy represses fibroblast to myofibroblast phenoconversion. Culturing unpassaged cardiac fibroblasts for 72 hours on plastic tissue culture plates is associated with elevated alpha-smooth muscle actin (alpha-SMA) expression. This activation parallels increased microtubule-associated protein 1A/1B-light chain 3 (LC-3beta II) protein expression. Inhibition of autophagy with bafilomycin-A1 (Baf-A1) and chloroquine (CQ) in cardiac fibroblasts significantly reduces alpha-SMA and extracellular domain A fibronectin (ED-A FN) protein vs untreated controls. Myofibroblast cell migration and contractility were significantly reduced following inhibition of autophagy. These data support the possibility of a causal link between cardiac fibroblast-to-myofibroblast phenoconversion and autophagy. PMID- 27705939 TI - The andean anticancer herbal product BIRM causes destabilization of androgen receptor and induces caspase-8 mediated-apoptosis in prostate cancer. AB - BIRM is an anticancer herbal formulation from Ecuador. Previous study established its antitumor and antimetastatic activity against prostate cancer models. The activity of BIRM against human prostate cancer (PCa) cells was investigated to uncover its mechanism of antitumor activity. In androgen receptor (AR)-expressing PCa cells BIRM was 2.5-fold (250%) more cytotoxic in presence of androgen (DHT) compared to cells grown in the absence of DHT. In AR-positive cells (LAPC-4 and LNCaP) BIRM caused a dose and time-dependent down-regulation of AR and increased apoptosis. Exposing cells to BIRM did not affect the synthesis of AR and AR promoter activity but increased degradation of AR via proteasome-pathway. BIRM caused destabilization of HSP90-AR association in LAPC-4 cells. It induced apoptosis in PCa cells by activation of caspase-8 via death receptor and FADD mediated pathways. A synthetic inhibitor of Caspase-8 cleavage (IETD-CHO) aborted BIRM-induced apoptosis. The effect of BIRM on AKT-mediated survival pathway in both AR+ and AR- negative (PC-3 and DU145) showed decreased levels of p-AKTser 473 in all PCa cell lines. BIRM dosed by oral gavage in mice bearing PC-3ML tumors showed selective efficacy on tumor growth; before tumors are established but limited efficacy when treated on existing tumors. Moreover, BIRM inhibited the LNCaP tumor generated by orthotropic implantation into dorsal prostate of nude mice. Partial purification of BIRM by liquid-liquid extraction and further fractionation by HPLC showed 4-fold increased specific activity on PCa cells. These results demonstrate a mechanistic basis of anti-tumor activity of the herbal extract BIRM. PMID- 27705940 TI - Combined targeting of SET and tyrosine kinases provides an effective therapeutic approach in human T-cell acute lymphoblastic leukemia. AB - Recent evidence suggests that inhibition of protein phosphatase 2A (PP2A) tumor suppressor activity via the SET oncoprotein contributes to the pathogenesis of various cancers. Here we demonstrate that both SET and c-MYC expression are frequently elevated in T-ALL cell lines and primary samples compared to healthy T cells. Treatment of T-ALL cells with the SET antagonist OP449 restored the activity of PP2A and reduced SET interaction with the PP2A catalytic subunit, resulting in a decrease in cell viability and c-MYC expression in a dose dependent manner. Since a tight balance between phosphatases and kinases is required for the growth of both normal and malignant cells, we sought to identify a kinase inhibitor that would synergize with SET antagonism. We tested various T ALL cell lines against a small-molecule inhibitor screen of 66 compounds targeting two-thirds of the tyrosine kinome and found that combined treatment of T-ALL cells with dovitinib, an orally active multi-targeted small-molecule receptor tyrosine kinase inhibitor, and OP449 synergistically reduced the viability of all tested T-ALL cell lines. Mechanistically, combined treatment with OP449 and dovitinib decreased total and phospho c-MYC levels and reduced ERK1/2, AKT, and p70S6 kinase activity in both NOTCH-dependent and independent T ALL cell lines. Overall, these results suggest that combined targeting of tyrosine kinases and activation of serine/threonine phosphatases may offer novel therapeutic strategies for the treatment of T-ALL. PMID- 27705941 TI - MicroRNA-22 negatively regulates poly(I:C)-triggered type I interferon and inflammatory cytokine production via targeting mitochondrial antiviral signaling protein (MAVS). AB - MicroRNAs (miRNAs) are small non-coding RNAs that play important roles in regulating the host immune response. Here we found that miR-22 is induced in glial cells upon stimulation with poly(I:C). Overexpression of miR-22 in the cultured cells resulted in decreased activity of interferon regulatory factor-3 and nuclear factor-kappa B, which in turn led to reduced expression of interferon beta and inflammatory cytokines, including tumor necrosis factor-alpha, interleukin-1beta, interleukin-6, and chemokine (C-C motif) ligand 5, upon stimulation with poly(I:C), whereas knockdown of miR-22 had the opposite effect. We used a combination of bioinformatics and experimental techniques to demonstrate that mitochondrial antiviral signaling protein (MAVS), which positively regulates type I interferon production, is a novel target of miR-22. Overexpression of miR-22 decreased the activity of a luciferase reporter containing the MAVS 3'-untranslated region and led to decreased MAVS mRNA and protein levels. In contrast, ectopic expression of miR-22 inhibitor led to elevated MAVS expression. Collectively, our results demonstrate that miR-22 negatively regulates poly(I:C)-induced production of type I interferon and inflammatory cytokines via targeting MAVS. PMID- 27705942 TI - RND3 promotes Snail 1 protein degradation and inhibits glioblastoma cell migration and invasion. AB - Activation of Snail1 signaling promotes the migration and invasion of multiple tumors, including glioblastoma multiforme (GBM). However, the molecular mechanism that augments Snail1 signaling during GBM cell migration and invasion remains largely unknown. Identification of the factors that regulate Snail1 signaling is critical to block tumor cell migration and invasion. By screening human GBM specimens, we found that the expression levels of small GTPase RND3 positively correlated with the expression levels of E-cadherin and claudin, the glioblastoma migration biomarkers negatively regulated by Snail1. Downregulation of E-cadherin and claudin has been associated with the migration and invasion of GBM cells. We demonstrated that RND3 functioned as an endogenous inhibitor of the Snail directed transcriptional regulation. RND3 physically interacted with Snail1 protein, enhanced Snail1 ubiquitination, and facilitated the protein degradation. Forced expression of RND3 inhibited Snail1 activity, which in turn blocked glioblastoma cell migration and invasion in vitro in cell culture and in vivo in GBM xenograft mice. In contrast, downregulation of RND3 augmented Snail1 activity, and subsequently decreased E-cadherin expression, eventually promoted glioblastoma cell migration and invasion. The pro-migration induced by RND3 downregulation was attenuated by Snail1 knockdown. The findings partially explain why Snail1 activity is augmented in GBM, and defines a new function of RND3 in GBM cell migration and invasion.

AB - Male factor infertility affects one-sixth of couples worldwide, and non obstructive azoospermia (NOA) is one of the most severe forms. In recent years there has been increasing evidence to implicate the participation of X chromosome in the process of spermatogenesis. To uncover the roles of X-linked multi-copy genes in spermatogenesis, we performed systematic analysis of X-linked gene copy number variations (CNVs) and Y chromosome haplogrouping in 447 idiopathic NOA patients and 485 healthy controls. Interestingly, the frequency of individuals with abnormal level copy of Variable charge, X-linked (VCX) was significantly different between cases and controls after multiple test correction (p = 5.10 * 10-5). To discriminate the effect of gain/loss copies in these genes, we analyzed the frequency of X-linked multi-copy genes in subjects among subdivided groups. Our results demonstrated that individuals with increased copy numbers of Nuclear RNA export factor 2 (NXF2) (p = 9.21 * 10-8) and VCX (p = 1.97 * 10-4) conferred the risk of NOA. In vitro analysis demonstrated that increasing copy number of VCX could upregulate the gene expression and regulate cell proliferation and apoptosis. Our study establishes a robust association between the VCX CNVs and NOA risk. PMID- 27705944 TI - Analysis of angiogenesis related factors in glioblastoma, peritumoral tissue and their derived cancer stem cells. AB - The formation of new blood vessels represents a crucial event under both physiological and pathological circumstances. In this study, we evaluated by immunohistochemistry, and/or Western blotting and/or quantitative real time-PCR the expression of HIF1alpha, HIF2alpha, VEGF, VEGFR1 and VEGFR2 in surgical glioblastoma multiforme (GBM) and peritumoral tissue samples obtained from 50 patients as well as in cancer stem cells (CSCs) isolated from GBM (GCSCs) and peritumoral tissue (PCSCs) of 5 patients. We also investigated the contribution of both GCSCs and PCSCs on the behavior of endothelial cells (ECs) in vitro. Immunohistochemistry demonstrated the expression of angiogenesis markers in both GBM and peritumoral tissue. In addition, in vitro tube formation assay indicated that both GCSCs and PCSCs stimulate EC proliferation as well as tube-like vessel formation. An increased migration aptitude was mainly observed when ECs were cultured in the presence of GCSCs rather than in the presence of PCSCs. These findings suggest that relevant neoangiogenetic events may occur in GBM. In particular, VEGF/VEGFR co-expression in PCSCs leads to hypothesize the involvement of an autocrine signaling. Moreover, our results suggest that both GCSCs and PCSCs own the skill of activating the "angiogenic switch" and the capability of modulating EC behavior, indicating that both cell types are either responsive to angiogenic stimuli or able to trigger angiogenic response. Together with our previous findings, this study adds a further piece to the challenging puzzle of the characterization of peritumoral tissue and of the definition of its real role in GBM pathophysiology. PMID- 27705945 TI - Interaction between susceptibility loci in cGAS-STING pathway, MHC gene and HPV infection on the risk of cervical precancerous lesions in Chinese population. AB - Human papillomavirus (HPV) infection is a definite risk factor for cervical cancer. Nevertheless, only some infected individuals actually develop cervical cancer. The cGAS-STING pathway in innate immunity plays an important role in protecting against HPV infection. Chen et al. described that the rs2516448 SNP in the MHC locus may affect susceptibility to cervical cancer, a finding that we attempted to replicate in a Chinese population. To investigate the effects of cGAS, STING and MHC polymorphisms on susceptibility to cervical precancerous lesions, 9 SNPs were analyzed in 164 cervical precancerous lesion cases and 428 controls. Gene-gene and gene-environment interactions were also evaluated. We found a significantly decreased risk of cervical precancerous lesions for the GG genotype of rs311678 in the cGAS gene (ORadjusted = 0.40, 95% CI: 0.16-0.98). Moreover, MDR analysis identified a significant three-locus interaction model, involving HPV infection, age at menarche and rs311678 in cGAS. Additionally, a significant antagonistic interaction between HPV infection and rs311678 was found on an additive scale. In conclusion, our results indicate that the rs311678 polymorphism in the cGAS gene confers genetic susceptibility to cervical precancerous lesions. Moreover, the three-way gene-environment interactions further demonstrate that the rs311678 polymorphism in cGAS can significantly decrease the risk of HPV infection and the elder at menarche. PMID- 27705946 TI - Necessity of organized low-dose computed tomography screening for lung cancer: From epidemiologic comparisons between China and the Western nations. AB - OBJECTIVES: To compare the proportion of stage I lung cancer and population mortality in China to those in U.S. and Europe where lung cancer screening by low dose computed tomography (LDCT) has been already well practiced. METHODS: The proportions of stage I lung cancer in LDCT screening population in U.S. and Europe were retrieved from NLST and NELSON trials. The general proportion of stage I lung cancer in China was retrieved from a rapid meta-analysis, based on a literature search in the China National Knowledge Infrastructure database. The lung cancer mortality and prevalence of China, U.S. and Europe was retrieved from Globocan 2012 fact sheet. Mortality-to-prevalence ratio (MPR) was applied to compare the population survival outcome of lung cancer. RESULTS: The estimated proportion of stage I lung cancer in China is merely 20.8% among hospital-based cross-sectional population, with relative ratios (RRs) being 2.40 (95% CI 2.18 2.65) and 2.98 (95% CI 2.62-3.38) compared by LDCT-screening population in U.S. and Europe trials, respectively. MPR of lung cancer is as high as 58.9% in China, with RRs being 0.46 (95% CI 0.31-0.67) and 0.58 (95% CI 0.39-0.85) compared by U.S. and Europe, respectively. CONCLUSIONS: By the epidemiological inference, the LDCT mass screening might be associated with increasing stage I lung cancer and therefore improving population survival outcome. How to translate the experiences of lung cancer screening by LDCT from developed counties to China in a cost effective manner needs to be further investigated. PMID- 27705947 TI - MiRNA203 suppresses the expression of protumorigenic STAT1 in glioblastoma to inhibit tumorigenesis. AB - MicroRNAs (miRNAs) play critical roles in regulating cancer cell proliferation, migration, survival and sensitivity to chemotherapy. The potential application of using miRNAs for cancer prognosis holds great promise but miRNAs with predictive value remain to be identified and underlying mechanisms of how they promote or suppress tumorigenesis are not completely understood. Here, we show a strong correlation between miR203 expression and brain cancer patient survival. Low miR203 expression is found in subsets of brain cancer patients, especially glioblastoma. Ectopic miR203 expression in glioblastoma cell lines inhibited cell proliferation and migration, increased sensitivity to apoptosis induced by interferon or temozolomide in vitro, and inhibited tumorigenesis in vivo. We further show that STAT1 is a direct functional target of miR203, and miR203 level is negatively correlated with STAT1 expression in brain cancer patients. Knockdown of STAT1 expression mimicked the effect of overexpression of miR203 in glioblastoma cell lines, and inhibited cell proliferation and migration, increased sensitivity to apoptosis induced by IFN or temozolomide in vitro, and inhibited glioblastoma tumorigenesis in vivo. High STAT1 expression significantly correlated with poor survival in brain cancer patients. Mechanistically, we found that enforced miR203 expression in glioblastoma suppressed STAT1 expression directly, as well as that of a number of STAT1 regulated genes. Taken together, our data suggest that miR203 acts as a tumor suppressor in glioblastoma by suppressing the pro-tumorigenic action of STAT1. MiR203 may serve as a predictive biomarker and potential therapeutic target in subsets of cancer patients with low miR203 expression. PMID- 27705948 TI - Survival prediction in patients undergoing radionuclide therapy based on intratumoral somatostatin-receptor heterogeneity. AB - The NETTER-1 trial demonstrated significantly improved progression-free survival (PFS) for peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors (NET) emphasizing the high demand for response prediction in appropriate candidates. In this multicenter study, we aimed to elucidate the prognostic value of tumor heterogeneity as assessed by somatostatin receptor (SSTR)-PET/CT. 141 patients with SSTR-expressing tumors were analyzed obtaining SSTR-PET/CT before PRRT (1-6 cycles, 177Lu somatostatin analog). Using the Interview Fusion Workstation (Mediso), a total of 872 metastases were manually segmented. Conventional PET parameters as well as textural features representing intratumoral heterogeneity were computed. The prognostic ability for PFS and overall survival (OS) were examined. After performing Cox regression, independent parameters were determined by ROC analysis to obtain cut-off values to be used for Kaplan-Meier analysis. Within follow-up (median, 43.1 months), 75 patients showed disease progression (median, 22.2 m) and 54 patients died (median, 27.6 m). Cox analysis identified 8 statistically independent heterogeneity parameters for time-to-progression and time-to-death. Among them, the textural feature Entropy predicted both PFS and OS. Conventional PET parameters failed in response prediction. Imaging-based heterogeneity assessment provides prognostic information in PRRT candidates and outperformed conventional PET parameters. Its implementation in clinical practice can pave the way for individualized patient management. PMID- 27705949 TI - Age-related decline in cardiac autonomic function is not attenuated with increased physical activity. AB - Age and physical inactivity are important risk factors for cardiovascular mortality. Heart rate response to exercise (HRRE) and heart rate recovery (HRR), measures of cardiac autonomic function, are strong predictors of mortality. The present study defined the effect of age and physical activity on HRRE and HRR. Healthy women (N=72) grouped according to age (young, 20-30 years; middle, 40-50 years; and older, 65-81 years) and daily physical activity (low active <7500, high active >12,500 steps/day) performed a maximal cardiopulmonary exercise test. The HRRE was defined as an increase in heart rate from rest to 1, 3 and 5 minutes of exercise and at 1/3 of total exercise time, and HRR as the difference in heart rate between peak exercise and 1, 2, and 3 minutes later. Age was associated with a significant decline in HRRE at 1 min and 1/3 of exercise time (r=-0.27, p=0.04, and r=-0.39, p=0.02) and HRR at 2 min and 3 min (r=-0.35, p=0.01, and r=-0.31, p=0.02). There was no significant difference in HRRE and HRR between high and low active middle-age and older women (p>0.05). Increased level of habitual physical activity level appears to have a limited effect on age-related decline in cardiac autonomic function in women. PMID- 27705951 TI - Electrical and thermal transport properties of the electron-doped cuprate Sm2-x Ce x CuO4-y system. AB - Electrical and thermal transport measurements were performed on thin films of the electron-doped superconductor Sm2-x Ce x CuO4-y (x = 0.13 - 0.19) in order to study the evolving nature of the charge carriers from the under-doped to over doped regime. A temperature versus cerium content (T - x) phase diagram has been constructed from the electrical transport measurements, yielding a superconducting region similar to that found for other electron-doped superconductors. Thermopower measurements show a dramatic change from the underdoped region (x < 0.15) to the overdoped region (x > 0.15). Application of the Fisher-Fisher-Huse (FFH) vortex glass scaling model to the magnetoresistance data was found to be insufficient to describe the data in the region of the vortex-solid to vortex-liquid transition. It was found instead that the modified vortex glass scaling model of Rydh, Rapp, and Anderson provided a good description of the data, indicating the importance of the applied field on the pinning landscape. A magnetic field versus temperature (H - T) phase diagram has also been constructed for the films with [Formula: see text], displaying the evolution of the vortex glass melting lines H g (T) across the superconducting regime. PMID- 27705950 TI - Evolution of renal function in African patients initiating second-line antiretroviral treatment: findings from the ANRS 12169 2LADY trial. AB - BACKGROUND: To investigate change in renal function in African patients initiating second-line antiretroviral therapy (ART) including ritonavir-boosted protease inhibitor (PI/r) with or without tenofovir disoproxil fumarate (TDF). METHODS: HIV-1-positive adults, failing standard first-line ART were randomized to either TDF/emtricitabine (FTC)+LPV/r, abacavir + didanosine +LPV/r or TDF/FTC+ darunavir (DRV)/r and followed for 18 months. Patients with an estimated glomerular filtration rate (eGFR) >=60 ml/min/1.73 m2 at baseline were included in this analysis. RESULTS: Data from 438 out of 454 randomized patients were analysed. Median age was 38 years and 72% were women. Initiation of PI/r-based second-line regimen induced a marked eGFR decline of -10.5 ml/min/1.73 m2 at week 4 in all treatment groups with a greater decrease in TDF/FTC+LPV/r arm (-15.1 ml/min/1.73 m2). At month 18, mean eGFR in the non-TDF containing regimen recovered its baseline level and was significantly greater than eGFR 18-month levels in the TDF-containing regimens that experienced only partial recovery (difference: -10.7; CI -16.8, -4.6; P=0.001 in TDF/FTC+LPV/r and -6.4; CI -12.5, 0.3; P=0.04 in TDF/FTC+DRV/r). At 18 months, prevalence of stage 3 chronic kidney disease was low (<3%) and not associated with treatment. One treatment discontinuation and five TDF dosage reductions for renal toxicities were reported in TDF-containing arms. CONCLUSIONS: Overall, these results suggest a reasonable renal tolerance of a regimen associating TDF/FTC+PI/r in African patients with eGFR>60 ml/ml/1.73 m2 at baseline. They also support the recommendation of reassessing renal function 1 month after initiation of treatment including ritonavir to account for the ritonavir-related artefactual decrease of eGFR and determine the new reference baseline value. PMID- 27705953 TI - The Coulomb-interaction-induced breaking of the Aufbau principle for the hole charging of InGaAs/GaAs quantum dots. AB - The so called 'incomplete hole shell filling' phenomenon, that is the breaking of the Aufbau principle was reported by Reuter et al (Phys. Rev. Lett. 94 026808) in the hole charging spectra of a quantum dot when the results were interpreted in the context of the s/p/d shell system-typical for electrons. We report an example of an inter-particle-interaction induced Aufbau principle violation even if it is applied to the one-particle Kohn-Luttinger eigenstates. We present a [Formula: see text]/configuration-interaction study that concerns multiple holes confined in an InGaAs/GaAs self-assembled cylindrical quantum dot. The eigenenergies and eigenvectors of up to six hole ground states were obtained-along with the corresponding one-hole orbital occupations-and discussed in the context of the Aufbau principle. PMID- 27705952 TI - Fast detection of covert visuospatial attention using hybrid N2pc and SSVEP features. AB - OBJECTIVE: Detecting the shift of covert visuospatial attention (CVSA) is vital for gaze-independent brain-computer interfaces (BCIs), which might be the only communication approach for severely disabled patients who cannot move their eyes. Although previous studies had demonstrated that it is feasible to use CVSA related electroencephalography (EEG) features to control a BCI system, the communication speed remains very low. This study aims to improve the speed and accuracy of CVSA detection by fusing EEG features of N2pc and steady-state visual evoked potential (SSVEP). APPROACH: A new paradigm was designed to code the left and right CVSA with the N2pc and SSVEP features, which were then decoded by a classification strategy based on canonical correlation analysis. Eleven subjects were recruited to perform an offline experiment in this study. Temporal waves, amplitudes, and topographies for brain responses related to N2pc and SSVEP were analyzed. The classification accuracy derived from the hybrid EEG features (SSVEP and N2pc) was compared with those using the single EEG features (SSVEP or N2pc). MAIN RESULTS: The N2pc could be significantly enhanced under certain conditions of SSVEP modulations. The hybrid EEG features achieved significantly higher accuracy than the single features. It obtained an average accuracy of 72.9% by using a data length of 400 ms after the attention shift. Moreover, the average accuracy reached ~80% (peak values above 90%) when using 2 s long data. SIGNIFICANCE: The results indicate that the combination of N2pc and SSVEP is effective for fast detection of CVSA. The proposed method could be a promising approach for implementing a gaze-independent BCI. PMID- 27705954 TI - Raman spectroscopy of K x Co2-y Se2 single crystals near the ferromagnet paramagnet transition. AB - Polarized Raman scattering spectra of the K x Co2-y Se2 single crystals reveal the presence of two phonon modes, assigned as of the A 1g and B 1g symmetry. The absence of additional modes excludes the possibility of vacancy ordering, unlike in K x Fe2-y Se2. The ferromagnetic (FM) phase transition at [Formula: see text] K leaves a clear fingerprint on the temperature dependence of the Raman mode energy and linewidth. For [Formula: see text] the temperature dependence looks conventional, driven by the thermal expansion and anharmonicity. The Raman modes are rather broad due to the electron-phonon coupling increased by the disorder and spin fluctuation effects. In the FM phase the phonon frequency of both modes increases, while an opposite trend is seen in their linewidth: the A 1g mode narrows in the FM phase, whereas the B 1g mode broadens. We argue that the large asymmetry and anomalous frequency shift of the B 1g mode is due to the coupling of spin fluctuations and vibration. Our density functional theory (DFT) calculations for the phonon frequencies agree rather well with the Raman measurements, with some discrepancy being expected since the DFT calculations neglect the spin fluctuations. PMID- 27705955 TI - Changing head model extent affects finite element predictions of transcranial direct current stimulation distributions. AB - OBJECTIVE: In this study, we determined efficient head model sizes relative to predicted current densities in transcranial direct current stimulation (tDCS). APPROACH: Efficiency measures were defined based on a finite element (FE) simulations performed using nine human head models derived from a single MRI data set, having extents varying from 60%-100% of the original axial range. Eleven tissue types, including anisotropic white matter, and three electrode montages (T7-T8, F3-right supraorbital, Cz-Oz) were used in the models. MAIN RESULTS: Reducing head volume extent from 100% to 60%, that is, varying the model's axial range from between the apex and C3 vertebra to one encompassing only apex to the superior cerebellum, was found to decrease the total modeling time by up to half. Differences between current density predictions in each model were quantified by using a relative difference measure (RDM). Our simulation results showed that [Formula: see text] was the least affected (a maximum of 10% error) for head volumes modeled from the apex to the base of the skull (60%-75% volume). SIGNIFICANCE: This finding suggested that the bone could act as a bioelectricity boundary and thus performing FE simulations of tDCS on the human head with models extending beyond the inferior skull may not be necessary in most cases to obtain reasonable precision in current density results. PMID- 27705956 TI - Using the detectability index to predict P300 speller performance. AB - OBJECTIVE: The P300 speller is a popular brain-computer interface (BCI) system that has been investigated as a potential communication alternative for individuals with severe neuromuscular limitations. To achieve acceptable accuracy levels for communication, the system requires repeated data measurements in a given signal condition to enhance the signal-to-noise ratio of elicited brain responses. These elicited brain responses, which are used as control signals, are embedded in noisy electroencephalography (EEG) data. The discriminability between target and non-target EEG responses defines a user's performance with the system. A previous P300 speller model has been proposed to estimate system accuracy given a certain amount of data collection. However, the approach was limited to a static stopping algorithm, i.e. averaging over a fixed number of measurements, and the row-column paradigm. A generalized method that is also applicable to dynamic stopping (DS) algorithms and other stimulus paradigms is desirable. APPROACH: We developed a new probabilistic model-based approach to predicting BCI performance, where performance functions can be derived analytically or via Monte Carlo methods. Within this framework, we introduce a new model for the P300 speller with the Bayesian DS algorithm, by simplifying a multi-hypothesis to a binary hypothesis problem using the likelihood ratio test. Under a normality assumption, the performance functions for the Bayesian algorithm can be parameterized with the detectability index, a measure which quantifies the discriminability between target and non-target EEG responses. MAIN RESULTS: Simulations with synthetic and empirical data provided initial verification of the proposed method of estimating performance with Bayesian DS using the detectability index. Analysis of results from previous online studies validated the proposed method. SIGNIFICANCE: The proposed method could serve as a useful tool to initially assess BCI performance without extensive online testing, in order to estimate the amount of data required to achieve a desired accuracy level. PMID- 27705957 TI - Interface mixing and its impact on exchange coupling in exchange biased systems. AB - Exchange bias and interlayer exchange coupling are interface driven phenomena. Since an ideal interface is very challenging to achieve, a clear understanding of the chemical and magnetic natures of interfaces is pivotal to identify their influence on the magnetism. We have chosen Ni80Fe20/CoO(t CoO)/Co trilayers as a model system, and identified non-stoichiometric Ni-ferrite and Co-ferrite at the surface and interface, respectively. These ferrites, being ferrimagnets typically, should influence the exchange coupling. However, in our trilayers the interface ferrites were found not to be ferro- or ferri-magnetic; thus having no observable influence on the exchange coupling. Our analysis also revealed that (i) interlayer exchange coupling was present between Ni80Fe20 and Co even though the interlayer thickness was significantly larger than expected for this phenomenon to happen, and (ii) the majority of the CoO layer (except some portion near the interface) did not contribute to the observed exchange bias. We also identified that the interlayer exchange coupling and the exchange bias properties were not interdependent. PMID- 27705959 TI - Neural mechanisms underlying catastrophic failure in human-machine interaction during aerial navigation. AB - OBJECTIVE: We investigated the neural correlates of workload buildup in a fine visuomotor task called the boundary avoidance task (BAT). The BAT has been known to induce naturally occurring failures of human-machine coupling in high performance aircraft that can potentially lead to a crash-these failures are termed pilot induced oscillations (PIOs). APPROACH: We recorded EEG and pupillometry data from human subjects engaged in a flight BAT simulated within a virtual 3D environment. MAIN RESULTS: We find that workload buildup in a BAT can be successfully decoded from oscillatory features in the electroencephalogram (EEG). Information in delta, theta, alpha, beta, and gamma spectral bands of the EEG all contribute to successful decoding, however gamma band activity with a lateralized somatosensory topography has the highest contribution, while theta band activity with a fronto-central topography has the most robust contribution in terms of real-world usability. We show that the output of the spectral decoder can be used to predict PIO susceptibility. We also find that workload buildup in the task induces pupil dilation, the magnitude of which is significantly correlated with the magnitude of the decoded EEG signals. These results suggest that PIOs may result from the dysregulation of cortical networks such as the locus coeruleus (LC)-anterior cingulate cortex (ACC) circuit. SIGNIFICANCE: Our findings may generalize to similar control failures in other cases of tight man machine coupling where gains and latencies in the control system must be inferred and compensated for by the human operators. A closed-loop intervention using neurophysiological decoding of workload buildup that targets the LC-ACC circuit may positively impact operator performance in such situations. PMID- 27705960 TI - Biorthogonal projected energies of a Gutzwiller similarity transformed Hamiltonian. AB - We present a method incorporating biorthogonal orbital-optimization, symmetry projection, and double-occupancy screening with a non-unitary similarity transformation generated by the Gutzwiller factor [Formula: see text], and apply it to the Hubbard model. Energies are calculated with mean-field computational scaling with high-quality results comparable to coupled cluster singles and doubles. This builds on previous work performing similarity transformations with more general, two-body Jastrow-style correlators. The theory is tested on 2D lattices ranging from small systems into the thermodynamic limit and is compared to available reference data. PMID- 27705958 TI - Chronic in vivo stability assessment of carbon fiber microelectrode arrays. AB - OBJECTIVE: Individual carbon fiber microelectrodes can record unit activity in both acute and semi-chronic (~1 month) implants. Additionally, new methods have been developed to insert a 16 channel array of carbon fiber microelectrodes. Before assessing the in vivo long-term viability of these arrays, accelerated soak tests were carried out to determine the most stable site coating material. Next, a multi-animal, multi-month, chronic implantation study was carried out with carbon fiber microelectrode arrays and silicon electrodes. APPROACH: Carbon fibers were first functionalized with one of two different formulations of PEDOT and subjected to accelerated aging in a heated water bath. After determining the best PEDOT formula to use, carbon fiber arrays were chronically implanted in rat motor cortex. Some rodents were also implanted with a single silicon electrode, while others received both. At the end of the study a subset of animals were perfused and the brain tissue sliced. Tissue sections were stained for astrocytes, microglia, and neurons. The local reactive responses were assessed using qualitative and quantitative methods. MAIN RESULTS: Electrophysiology recordings showed the carbon fibers detecting unit activity for at least 3 months with average amplitudes of ~200 MUV. Histology analysis showed the carbon fiber arrays with a minimal to non-existent glial scarring response with no adverse effects on neuronal density. Silicon electrodes showed large glial scarring that impacted neuronal counts. SIGNIFICANCE: This study has validated the use of carbon fiber microelectrode arrays as a chronic neural recording technology. These electrodes have demonstrated the ability to detect single units with high amplitude over 3 months, and show the potential to record for even longer periods. In addition, the minimal reactive response should hold stable indefinitely, as any response by the immune system may reach a steady state after 12 weeks. PMID- 27705962 TI - Asymptotic behavior of impurity-induced bound states in low-dimensional topological superconductors. AB - We study theoretically the asymptotic behavior of the Shiba bound states associated with magnetic impurities embedded in both 2D and 1D anomalous superconductors. We calculate analytically the spatial dependence of the local density of states together with the spin polarization associated with the Shiba bound states. We show that the latter quantity exhibits drastic differences between s-wave and different types of p-wave superconductors. Such properties, which could be measured using spin-polarized STM, offer therefore a way to discriminate between singlet and triplet pairing in low-dimensional superconductors, as well as a way to estimate the amplitude of the triplet pairing in these systems. PMID- 27705961 TI - Muscle-tendon units localization and activation level analysis based on high density surface EMG array and NMF algorithm. AB - OBJECTIVE: Some skeletal muscles can be subdivided into smaller segments called muscle-tendon units (MTUs). The purpose of this paper is to propose a framework to locate the active region of the corresponding MTUs within a single skeletal muscle and to analyze the activation level varieties of different MTUs during a dynamic motion task. APPROACH: Biceps brachii and gastrocnemius were selected as targeted muscles and three dynamic motion tasks were designed and studied. Eight healthy male subjects participated in the data collection experiments, and 128 channel surface electromyographic (sEMG) signals were collected with a high density sEMG electrode grid (a grid consists of 8 rows and 16 columns). Then the sEMG envelopes matrix was factorized into a matrix of weighting vectors and a matrix of time-varying coefficients by nonnegative matrix factorization algorithm. MAIN RESULTS: The experimental results demonstrated that the weightings vectors, which represent invariant pattern of muscle activity across all channels, could be used to estimate the location of MTUs and the time-varying coefficients could be used to depict the variation of MTUs activation level during dynamic motion task. SIGNIFICANCE: The proposed method provides one way to analyze in-depth the functional state of MTUs during dynamic tasks and thus can be employed on multiple noteworthy sEMG-based applications such as muscle force estimation, muscle fatigue research and the control of myoelectric prostheses. PMID- 27705963 TI - Identifying auditory attention with ear-EEG: cEEGrid versus high-density cap-EEG comparison. AB - OBJECTIVE: This study presents a direct comparison of a classical EEG cap setup with a new around-the-ear electrode array (cEEGrid) to gain a better understanding of the potential of ear-centered EEG. APPROACH: Concurrent EEG was recorded from a classical scalp EEG cap and two cEEGrids that were placed around the left and the right ear. Twenty participants performed a spatial auditory attention task in which three sound streams were presented simultaneously. The sound streams were three seconds long and differed in the direction of origin (front, left, right) and the number of beats (3, 4, 5 respectively), as well as the timbre and pitch. The participants had to attend to either the left or the right sound stream. MAIN RESULTS: We found clear attention modulated ERP effects reflecting the attended sound stream for both electrode setups, which agreed in morphology and effect size. A single-trial template matching classification showed that the direction of attention could be decoded significantly above chance (50%) for at least 16 out of 20 participants for both systems. The comparably high classification results of the single trial analysis underline the quality of the signal recorded with the cEEGrids. SIGNIFICANCE: These findings are further evidence for the feasibility of around the-ear EEG recordings and demonstrate that well described ERPs can be measured. We conclude that concealed behind-the-ear EEG recordings can be an alternative to classical cap EEG acquisition for auditory attention monitoring. PMID- 27705964 TI - Interaction with the MAPT H1H1 Genotype Increases Dementia Risk in APOE epsilon4 Carriers in a Population of Southern India. AB - BACKGROUND: This study delineates the role of the interaction of apolipoprotein E (APOE) and MAPT alleles in contributing to disease risks of dementia in a southern Indian population. METHODS: A sample of 419 patients comprising Alzheimer's disease (AD; n = 156), mild cognitive impairment (MCI; n = 87), frontotemporal dementia (FTD; n = 127), vascular dementia (VD; n = 37), and dementia with Lewy bodies (DLB; n = 12) was analysed in comparison with a control group (n = 138). APOE genotyping and MAPT haplotyping were performed on all study subjects. RESULTS: Multivariate logistic regression analysis showed that variability on the APOE locus influenced the relative risk of dementia in the study population. The APOE epsilon4 allele increased the disease risk most significantly for AD (OR = 3.468, p < 0.0001) and MCI (OR = 2.901, p < 0.0001). The APOE epsilon2 allele remained protective for AD (OR = 0.205, p < 0.05). For FTD, VD, and DLB, the APOE epsilon4 allele was ineffectual in modulating disease risk. The MAPT H1 haplotype was not an overrepresented marker of neurodegenerative diseases. The H1H1 genotype had an additive effect in contributing to either disease risk in combination with the APOE epsilon4 allele or protection in combination with the APOE epsilon2 or epsilon3 allele. CONCLUSIONS: This study is a reappraisal of the strong association of APOE variability with AD in southern India when compared to other dementia groups, while the transcriptional differences between MAPT haplotypes have a limited role in Indian dementia patients. PMID- 27705965 TI - High Prognostic Value of Mini-Laparoscopy for Advanced Liver Disease-Related Complications in Patients with HCV Infection. AB - BACKGROUND/AIM: The assessment of advanced chronic liver disease (ACLD) is a prerequisite for therapy and surveillance in patients with chronic hepatitis C infection. Mini-laparoscopy-assisted liver biopsies facilitate both histological and macroscopical evaluation of liver fibrosis. This study is aimed at investigating the prognostic significance of the laparoscopic assessment for the cumulative incidence of ACLD-related events. PATIENTS AND METHODS: We performed a single center, retrospective analysis of 94 patients with either macroscopically or/and microscopically assessed advanced fibrosis/cirrhosis caused by chronic hepatitis C infection. The patients' data, the respective laboratory results, and follow-up period were evaluated in the outpatient clinic. RESULTS: The group with both macro- and microscopic diagnosed ACLD showed a significantly higher number of decompensating events (n = 7) compared with the other 2 groups (n = 0 in the group with only histological and n = 1 in the group with only laparoscopic diagnosis of advanced liver disease). The results were not affected by the successful treatment of the hepatitis C virus. In the Cox-regression analysis, the spleen size (>120 mm) was significantly associated with the incidence of ACLD related events. CONCLUSIONS: Assessment of ACLD in chronic hepatitis C by mini laparoscopy-assisted liver biopsies may facilitate the selection of patients with a poor prognosis, irrespective of achieving a sustained virological response following treatment. Follow-up of these patients should be intensified to treat decompensation early. PMID- 27705967 TI - Evaluating the Utility of a 'N-of-1' Precision Cancer Medicine Strategy: The Case for 'Time-to-Subsequent-Disease Progression'. AB - It is increasingly recognized that cancer is a highly heterogeneous group of illnesses even within a particular organ site (e.g., breast, lung, colon, etc.). This observation presents a serious challenge to the traditional concept of phase 3 randomized trials designed to define therapeutic efficacy of a novel treatment strategy. For while 10% of the patients with a common malignancy (e.g., non-small cell lung cancer) may be sufficient to consider such an effort, enrolling a sufficient number of patients into a clinical trial in a timely manner to define clinical utility would be extremely difficult if the population in question represented only 1% of this population, and essentially impossible if one wished to explore the benefits of treatment in a rarer neoplasm (e.g. ovarian cancer). Therefore, in the new era of precision cancer medicine, alternative research designs are imperative. One option would be to compare the time-to-disease progression of an individual cancer patient following treatment with a novel therapeutic to the time-to-disease progression for that specific patient on her/his immediately preceding treatment. The rationale for this strategy and early experience with this innovative approach to evaluating the efficacy of anticancer therapy is highlighted in this report. PMID- 27705966 TI - Prolonged Treatment of Peanut-Allergic Mice with Bortezomib Significantly Reduces Serum Anti-Peanut IgE but Does Not Affect Allergic Symptoms. AB - BACKGROUND: Anti-peanut immunoglobulin E (anti-Pn IgE) can persist throughout life, suggesting that this condition could be maintained by long-lived antibody secreting cells (ASCs). To determine the role of long-lived ASCs, peanut-allergic mice underwent prolonged treatment with the proteasome inhibitor, bortezomib (Bz). METHODS: Intravenous Bz was given twice weekly for 21 weeks to peanut allergic mice. During treatment, serum anti-Pn IgE was measured, and the mice were rechallenged at the end of treatment. Cell populations were measured, and Pn specific IgG, total IgG, and total IgE ASCs were enumerated in the bone marrow (BM) and spleen (SPL). RESULTS: Prolonged treatment with Bz significantly reduced serum anti-Pn IgE and IgG1 but did not affect symptoms following challenge with Pn, even in mice with undetectable serum anti-Pn IgE. Numbers of CD138+ cells were significantly reduced in the BM but were unaffected in the SPL. Unexpectedly, Bz did not affect numbers of Pn-specific IgG, total IgG, or total IgE ASCs in either the BM or SPL. CONCLUSIONS: Cells that maintain long-lived serum anti-Pn IgE are sensitive to Bz. However, prolonged depletion of serum Pn specific IgE does not result in a decrease of symptoms following challenge with Pn.

AB - Dental caries levels have declined in children since the 1970s in many countries. Most of the postulated main reasons for the decline are speculative and have not been rigorously evaluated. The objective of this study was to assess the relationship between some social factors and the decline in dental caries in Brazilian 12-year-old children from 1996 to 2010. Secondary analysis of national data was performed in 27 Brazilian state capitals. A panel data regression model with fixed effects and multiple linear regression were used to verify the relationship between the explanatory and the dependent variables and also the time-trend effect. The results showed that the DMFT (decayed, missing, and filled teeth) decreased by about 3% per year, and the percentage of caries-free children increased by 4.5% per year. For DMFT and percentage caries free, the results for the panel data regression showed a significant association for the Human Development Index (HDI) in the adjusted model (p = 0.010). When the overall changes over time were compared, the Gini index had a significant association with the overall change in DMFT in the final model of the multiple regression analysis (p = 0.033). Our results indicate that the maintenance of good levels of human development, which includes better education, income, and longevity, are important factors relating to improving levels of oral health in 12-year-old Brazilian children. However, to accelerate this process in cities with the worst caries situation, income inequality should be tackled. PMID- 27705969 TI - Non-Invasive Haemodynamic Monitoring in Pregnancy: A Comparative Study Using Ultrasound and Bioreactance. AB - BACKGROUND: Due to the importance of cardiovascular dysfunction and advances in the development and use of non-invasive cardiac output (CO) monitoring devices, there is a growing interest in their use in the obstetric population. The aim of this study was to compare two commercially available, non-invasive CO monitors in the assessment of heart rate (HR), stroke volume (SV), CO, cardiac index (CI) and total peripheral resistance (TPR) in an obstetric population. METHODS: This was a prospective, comparative study including two groups. A normotensive group, which consisted of uncomplicated healthy pregnancies, and a hypertensive group, which consisted of those complicated by hypertensive disorders of pregnancy. Non invasive cardiovascular assessments were performed using two methodologies. USCOM(r) is an operator-dependent Doppler ultrasound device which obtains velocity time integrals of transaortic blood flow at the left ventricular outflow tract, while NICOM(r) provides an operator-independent haemodynamic profile by assessing thoracic voltage changes (bioreactance) which reflect pulsatile blood flow in the thorax. Correlation coefficients were derived, and Bland-Altman analysis was performed to derive the mean percentage difference (MPD) between the devices. RESULTS: 598 women were recruited for this study. In the normotensive group, 524 paired results were analysed, while 74 paired results were analysed in the hypertensive group. In the normotensive group, we found excellent correlation between USCOM(r) and NICOM(r) for HR (r = 0.885, p < 0.05), and moderate correlations for SV (r = 0.445, p < 0.05), CO (r = 0.529, p < 0.05), CI (r = 0.385, p < 0.05) and TPR (r = 0.524, p < 0.05). In the hypertensive group, we obtained similar correlations (HR: r = 0.877, p < 0.05; SV: r = 0.575, p < 0.05; CO: r = 0.601, p < 0.05; TPR: r = 0.589, p < 0.05). Bland-Altman analysis found that the agreement between both methodologies improved as gestation advances, with an MPD of 34% for CO estimation in the third trimester of uncomplicated pregnancies, and 39% in pregnancies complicated by hypertensive disorders. CONCLUSION: Our findings suggest that the two methodologies perform similarly in both uncomplicated pregnancies and in pregnancies complicated by hypertensive disorders. The study findings do not preclude the use of USCOM(r) and NICOM(r) devices in pregnancy, but indicate that these platforms cannot be used interchangeably. Our findings demonstrate an improvement in MPD as gestation advances and, therefore, questions the validity of previous longitudinal studies investigating maternal haemodynamics using these methodologies. Our work also highlights the need to construct reference ranges for each device and for validation of each methodology against a reference method before their use in research or clinical practice. PMID- 27705970 TI - Successful in utero Percutaneous Fetoscopic Release of a Wrapped Pleuro-Amniotic Shunt around the Fetal Arm: Case Report and Review of the Literature. AB - BACKGROUND AND OBJECTIVES: Fetal pleural effusions are either primary or secondary to chromosomal or structural fetal abnormalities. In both cases, thoraco-amniotic shunts may be indicated to prevent life-threatening consequences. In this report, we describe a rare complication of shunts and successful in utero management of this complication. We also summarize the prior reports of shunt wrapping around fetal limbs and successful prenatal release of the shunts. DATA SOURCE: Search including PubMed, MEDLINE and EMBASE databases from inception till November 2015 was conducted for cases with shunt entrapment around fetal limbs with or without prenatal management. RESULTS: Four cases including our case have been reported in the literature with wrapping of shunts around fetal limbs. Three of these cases were successfully managed prenatally using different interventional and anesthetic techniques. CONCLUSIONS: Prenatal shunts could be rarely complicated by wrapping of the shunt around fetal limbs with possible serious vascular and neurological consequences. Different techniques have been described for prenatal management of this condition. We describe a less invasive approach that could be done under local anesthesia in suitable cases. PMID- 27705971 TI - Low Density Lipoprotein Cholesterol and the Outcome of Acute Ischemic Stroke: Results of a Large Hospital-Based Study. AB - Studies show inconsistent associations between low-density lipoprotein cholesterol (LDL-C) and stroke outcome. We assessed these associations among patients with first-ever acute ischemic stroke (AIS) in China. Patients with first-ever AIS were categorized into 3 groups: normal LDL, marginally elevated LDL and high LDL - according to the LDL-C values on admission. The outcome measures that were investigated in each group included mortality, dependence and recurrence of vascular events. Patients with high LDL-C had higher mortality rates than did those with normal LDL-C at both 12 and 36 months, but this difference disappeared after adjustment for covariates. There was no difference between groups in mortality at 3 months and dependency or recurrence at 3, 12 or 36 months. LDL-C level was associated with long-term mortality after stroke, but was not an independent prognostic factor. PMID- 27705972 TI - Third-Line Chemotherapy with Irinotecan plus 5-Fluorouracil in Caucasian Metastatic Gastric Cancer Patients. AB - PURPOSE: The aim of this study was to evaluate the activity of the combination of 5-fluorouracil/folinic acid and irinotecan (FOLFIRI) as third-line chemotherapy (CT) in metastatic gastric cancer (mGC) patients pretreated with platinum derivatives, fluoropyrimidines, and taxanes. METHODS: We prospectively collected data of mGC patients treated with third-line FOLFIRI at our institution from 2009 to 2014. Eligible patients should be treated with a fluoropyrimidine-platinum first-line CT and a subsequent taxane-based second-line CT. FOLFIRI consisted of irinotecan 180 mg/m2 and leucovorin 200 mg/m2, followed by 5-fluorouracil 2,800 mg/m2 (administered as 48-hour i.v. continuous infusion from day 1 to 3), with cycles repeated every 2 weeks. Response rate (RR) was evaluated according to RECIST version 1.0, while progression-free (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method. RESULTS: A total of 33 patients were included. The majority (97%) had good performance status (0-1 according to ECOG), while median PFS after first-line and second-line CT was 5.2 and 4.4 months, respectively. Two patients experienced an objective response (RR: 6%), while 14 patients achieved disease stabilization (disease control rate: 42%). Median PFS and OS from the start of third-line CT were 3.3 and 7.5 months, respectively. Hematological and nonhematological grade 3-4 toxicities were uncommon and included neutropenia (6.1%), diarrhea (9.1%), vomiting (3%), and asthenia (3%). Febrile neutropenia was not reported. CONCLUSIONS: Third-line CT with FOLFIRI may be an option in heavily pretreated mGC patients with preserved performance status and organ function. This regimen has a favorable safety profile, and signs of activity have been observed after standard first- and second-line CT. PMID- 27705973 TI - Utility of Three-Dimensional Ultrasonography to Assess the Position of Essure Tubal Occlusion Device and Its Complications. AB - BACKGROUND: To determine the utility of three-dimensional (3D) sonography to control the position of hysteroscopic sterilizing device compared to hysterosalpingography (HSG). METHODS: A prospective observational study was carried out on 139 patients who underwent hysteroscopic tubal occlusion method between February 2012 and May 2013. Patients underwent 3D ultrasound scan to control device positioning, and they also underwent HSG as an additional control method. Comparison between both methods was carried out. RESULTS: In all, 17 (12.2%) devices were inserted due to a hydrosalpinx and 122 (87.8%) due to sterilization purposes. In 124 (89.2%) cases, sonography correlated completely to HSG findings. Sonography-positive predictive value was 89.5% to detect correct device positioning. Just 4 (2.8%) patients did not present complete tubal occlusion 3 months after device insertion; one of them presented device expulsion, 2 of them presented previous hydrosalpinx (tubal occlusion was confirmed after 6 months), and the last case rejected to undergo further controls but device seem to be effective. CONCLUSIONS: 3D sonography seems to be effective for the control of sterilization device positioning, but it also detects insertion complications and device migration. Further studies would be required to assess our findings and the role of sonography in case of hydrosalpinx. PMID- 27705974 TI - Myeloperoxidase Anti-Neutrophil Cytoplasmic Antibody-Positive Interstitial Pneumonia Associated with Granulomatosis with Polyangiitis Diagnosed by Surgical Lung Biopsy. AB - Granulomatosis with polyangiitis (GPA) is a rare systemic vasculitis that often involves the lung. However, interstitial pneumonia (IP) is rarely seen in GPA patients. We herein report 3 cases of IP associated with GPA diagnosed by surgical lung biopsy. High-resolution CT showed uniform subpleural reticular opacity with traction bronchiectasis. Biopsies from all 3 patients revealed neutrophilic capillaritis, microabscesses with giant cells, and coexisting histological findings of usual IP pattern or fibrosing nonspecific IP pattern. All 3 patients had elevated levels of serum myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA), but not proteinase 3-ANCA. We diagnosed GPA and treated with corticosteroid and cyclophosphamide. Follow-up CT showed improvement of the lesions in all patients. Surgical lung biopsy specimens which revealed GPA enabled us to conduct the most suitable therapy. This report indicates the importance of surgical lung biopsy for differentiating idiopathic IPs from GPA associated IP and suggests a relationship between MPO-ANCA and IP in GPA. PMID- 27705975 TI - Frequency and Determinants of Adherence to Oral Anticoagulants in Stroke Patients with Atrial Fibrillation in Clinical Practice. AB - BACKGROUND: Vitamin K antagonists (VKAs) and non-VKA oral anticoagulants (NOACs) are beneficial in patients with stroke and atrial fibrillation (AF). However, little is known about frequency and determinants of adherence to NOACs/VKAs in clinical practice. METHODS: This is a single-center explorative study from the Novel Oral Anticoagulants in Stroke Patients (NOACISP)-LONGTERM registry. We included consecutive AF-stroke patients treated with NOACs/VKAs and followed up for 3-24 months. Adherence was assessed at follow-up using structured interviews and quantified as the proportion of prescribed doses taken (PDT). Outcome measures were (i) full adherence, (ii) >=95% adherence and (iii) >=80% adherence (i.e., PDT 100/>=95/>=80%). To explore determinants of full adherence, we compared characteristics of fully and non-fully adherent patients. RESULTS: A total of 218 of 251 (86.9%) patients (48% female, mean age 77.9 +/- 9.1 years, 78% NOACs; 22% VKAs) were eligible for analysis with a median follow-up of 12 months: fully adherent were 78.4% patients (NOACs 77.1%, VKAs 83.3%, p = 0.35), >=95% adherent were 95.4% and >=80% adherent were 97.2%. Fully adherent patients took more pills daily (median (interquartile range) 7 (5-10) vs. 6 (4-8), p = 0.039), had more often previous antithrombotic treatment (70.8 vs. 53.2%, p = 0.023), caregiver-assisted medication administration (54.2 vs. 19.1%, p < 0.001) and functional dependency (32.8 vs. 15%, p = 0.011) than non-fully adherent patients. CONCLUSIONS: Full adherence was frequent. Patients naive to antithrombotics, taking few pills, which they self-administer, were at the highest risk of non-adherence and may benefit most from adherence-enhancing interventions.

PMID- 27705977 TI - The Prognostic Value of Red Blood Cell Distribution Width in Patients on Maintenance Hemodialysis. AB - AIMS: To examine the association between red blood cell distribution width (RDW) and mortality in hemodialysis (HD) patients. METHODS: Three hundred fifty six patients on HD for >3 months were enrolled and followed for 2 years. Patients were divided into 2 groups according to the median RDW value. Patient survival and risk factors for mortality were investigated. RESULTS: The 2-year survival rate was significantly lower in the high-RDW group (>14.9%; log-rank = 10.00, p = 0.0016). RDW (hazard ratio (HR) 1.34, 95% CI 1.04-1.71, p = 0.021), hemoglobin (HR 0.98, 95% CI 0.96-1.00, p = 0.023) and albumin (HR 0.90, 95% CI 0.82-0.99, p = 0.026) were independent predictors of mortality. Receiver operating characteristic curves of RDW to predict 2-year mortality had an area under the curve of 0.6487 (95% CI 0.5714-0.7260). CONCLUSIONS: Abnormal RDW was common in HD patients and significantly related with poor outcomes in these patients. PMID- 27705978 TI - Correlation or Limits of Agreement? Applying the Bland-Altman Approach to the Comparison of Cognitive Screening Instruments. AB - BACKGROUND/AIMS: Calculation of correlation coefficients is often undertaken as a way of comparing different cognitive screening instruments (CSIs). However, test scores may correlate but not agree, and high correlation may mask lack of agreement between scores. The aim of this study was to use the methodology of Bland and Altman to calculate limits of agreement between the scores of selected CSIs and contrast the findings with Pearson's product moment correlation coefficients between the test scores of the same instruments. METHODS: Datasets from three pragmatic diagnostic accuracy studies which examined the Mini-Mental State Examination (MMSE) vs. the Montreal Cognitive Assessment (MoCA), the MMSE vs. the Mini-Addenbrooke's Cognitive Examination (M-ACE), and the M-ACE vs. the MoCA were analysed to calculate correlation coefficients and limits of agreement between test scores. RESULTS: Although test scores were highly correlated (all >0.8), calculated limits of agreement were broad (all >10 points), and in one case, MMSE vs. M-ACE, was >15 points. CONCLUSION: Correlation is not agreement. Highly correlated test scores may conceal broad limits of agreement, consistent with the different emphases of different tests with respect to the cognitive domains examined. Routine incorporation of limits of agreement into diagnostic accuracy studies which compare different tests merits consideration, to enable clinicians to judge whether or not their agreement is close. PMID- 27705980 TI - ST-Segment Elevation Myocardial Infarction in Dialysis and Renal Transplant Patients. How Does It Compare to That in the General Population? PMID- 27705979 TI - Functional Expression of an Osmosensitive Cation Channel, Transient Receptor Potential Vanilloid 4, in Rat Vestibular Ganglia. AB - Transient receptor potential vanilloid (TRPV) 4 is a nonselective cation channel expressed in sensory neurons such as those in the dorsal root and trigeminal ganglia, kidney, and inner ear. TRPV4 is activated by mechanical stress, heat, low osmotic pressure, low pH, and phorbol derivatives such as 4alpha-phorbol 12,13-didecanoate (4alpha-PDD). We investigated the expression of TRPV4 in rat vestibular ganglion (VG) neurons. The TRPV4 gene was successfully amplified from VG neuron mRNA using reverse-transcription polymerase chain reaction. Furthermore, immunoblotting showed positive expression of TRPV4 protein in VG neurons. Immunohistochemistry indicated that TRPV4 was localized predominantly on the plasma membrane of VG neurons. Calcium (Ca2+) imaging of VG neurons showed that 4alpha-PDD and/or hypotonic stimuli caused an increase in intracellular Ca2+ concentration ([Ca2+]i) that was almost completely inhibited by ruthenium red, a selective antagonist of TRPV channels. Interestingly, a [Ca2+]i increase was evoked by both hypotonic stimuli and 4alpha-PDD in approximately 38% of VG neurons. These data indicate that TRPV4 is functionally expressed in VG neurons as an ion channel and that TRPV4 likely participates in VG neurons for vestibular neurotransmission as an osmoreceptor and/or mechanoreceptor. PMID- 27705981 TI - National Impact of Maintenance Dialysis or Renal Transplantation on Outcomes Following ST Elevation Myocardial Infarction. AB - BACKGROUND: Though cardiovascular disease is an important cause of mortality in patients with end-stage renal disease, epidemiology of ST-elevation myocardial infarction (STEMI) is less well described in this population. METHODS: This study included STEMI hospitalizations in patients aged >=20 using Nationwide Inpatient Sample Database from 2006 to 2010. Primary outcomes were incidence and trends of STEMI hospitalizations based on renal function status. We also looked at utilization of revascularization procedures, all-cause-hospital mortality and predictors of mortality. RESULTS: Of the estimated 882,447 STEMI hospitalizations, 11,383 were on maintenance dialysis and 1,076 had renal transplants. The incidence of STEMI was over 7 times in patients on maintenance dialysis and 1.73 times in renal transplant recipients compared to the general population. This incidence has however declined in those on maintenance dialysis (p for trend <0.001) to a greater extent than the general population and patients with renal transplant. Utilization of revascularization procedures was lowest in patients on maintenance dialysis (51.6 vs. 73.3% in renal transplant recipients and 77.0% in general population; p < 0.001) and mortality was highest (21.6 vs. 10.9 vs. 6.8%; p < 0.001). Being on maintenance dialysis or having a renal transplant were both independent predictors of mortality in patients hospitalized with STEMI. There was a differential effect of cardiac catheterization on odds of mortality with lesser impact in patients on maintenance dialysis. CONCLUSIONS: STEMI hospitalizations are more common in patients on maintenance dialysis and with renal transplants. The utilization of revascularizations procedures remains low and mortality high in these patients. PMID- 27705982 TI - The Impact of Team-Based Learning (TBL) on Physician Assistant Students' Academic Performance in Gross Anatomy. AB - PURPOSE: Changes in medical education have prevented students from conducting full cadaveric dissections in gross anatomy. The efficacy of alternative educational methods is being explored to augment traditional dissection. METHODS: Team-based learning was integrated into the 2014 gross anatomy laboratory for physician assistants (PA) and nurse anesthetists. Deidentified data from the 2013 and 2014 courses were used to assess with t-tests the effect of this addition on student academic performance. RESULTS: Students in the 2014 course who experienced team-based learning performed significantly better on 75% of written and laboratory practical examinations (P < .05). Those mean examination increases correlated with a positive shift in final grades. A greater benefit was noted for PA students than for nurse anesthetist students. CONCLUSIONS: Team-based learning is an effective supplement to cadaveric dissection. Student short-term knowledge outcomes improve with the combination of dissection and team-based learning in the gross anatomy laboratory. PMID- 27705984 TI - Pediatric Acute Respiratory Distress Syndrome: Has Assessing Risk of Mortality Become Simpler? PMID- 27705983 TI - Outcome Comparison in Children Undergoing Extracorporeal Life Support Initiated at a Local Hospital by a Mobile Cardiorespiratory Assistance Unit or at a Referral Center. AB - PURPOSE: To compare characteristics and outcome in children undergoing extracorporeal life support initiated in an extracorporeal life support center or at the patient's bedside in a local hospital, by means of a mobile cardiorespiratory assistance unit. METHODS: A retrospective study in a single PICU during 6 years. Extracorporeal life support was started either in our center (control group) or in the local hospital (mobile cardiorespiratory assistance unit group). The data collected were demographics, markers of patient's preextracorporeal life support condition, and outcome. RESULTS: One hundred twenty-six children underwent extracorporeal life support, 105 in the control group and 21 in the mobile cardiorespiratory assistance unit group. There was no difference between groups in terms of age, weight, or Pediatric Risk of Mortality II score. There was a significant difference in organ failure etiology between groups, with more respiratory cases in the mobile cardiorespiratory assistance unit group (76.2%) and more cardiac surgery cases in the control group (60%; p < 0.001). The duration of extracorporeal life support was longer in the mobile cardiorespiratory assistance unit group than in the control group (10 [1-36] vs 5 [0-33] d; p = 0.003). PICU length of stay and mortality (60% vs 47.6%; p = 0.294) were not significantly different between the two groups. To allow comparison of a more homogenous population, a subgroup analysis was performed including only respiratory failure patients from the two groups (R-control group [n = 22] and R mobile cardiorespiratory assistance unit group [n = 16]). PICU length of stay was 17 (3-64) days in the R-control group and 23 (1-45) days in the R-mobile cardiorespiratory assistance unit group (p = 0.564), and PICU mortality rate was 54.5% in the R-control group and 43.8% in the R-mobile cardiorespiratory assistance unit group (p = 0.511). There was no difference between the R-groups for age, weight, Pediatric Risk of Mortality II score, and markers of kidney or liver dysfunction, and lactate blood levels. CONCLUSION: Extracorporeal life support can be safely initiated at children's bedside in the local hospital and then transported to the specialized referral center. Our results support the validity of an interregional organization of mobile cardiorespiratory assistance unit teams.

AB - PURPOSE: To report the prevalence and risk factors of stress urinary incontinence (SUI) and the prevalence of intrinsic sphincter deficiency in women with multiple sclerosis (MS). METHODS: We conducted a retrospective study. Female patients with MS, followed for lower urinary tract symptoms (LUTS) during a 15-year period were included. Demographic data, MS history, expanded disability status scale (EDSS) score at the urodynamic visit, obstetrical past, birth weight, LUTS, and urodynamic findings were collected. SUI was defined as incontinence during cough, or any effort. A maximum urethral closure pressure less than 30 cm H2O defined intrinsic sphincter deficiency. RESULTS: We included 363 women with a mean age of 46.7+/-10.8 years and a mean disease duration of 12.9+/-8.7 years. The incidence of relapsing remitting MS, a secondary progressive form, and a primary progressive form was 60.6%, 32.8%, and 6.6%, respectively. The prevalence of SUI was 31.4%. The prevalence of intrinsic sphincter deficiency was 1.4% and 0.8% of these patients had a SUI (P=0.300). In a multivariate analysis, women with a SUI had significantly higher birth weight (P=0.030), a pelvic organ prolapse (P=0.021), urgent urinary incontinence (P=0.006), a lower EDSS score (P=0.019), and a weaker containing effort (P<0.001). CONCLUSIONS: The prevalence of SUI in women with MS was 31.4%. This symptom could affect the quality of life of women with MS. PMID- 27706006 TI - Percutaneous Nerve Evaluation Test Versus Staged Test Trials for Sacral Neuromodulation: Sensitivity, Specificity, and Predictive Values of Each Technique. AB - PURPOSE: InterStim device is an U.S. Food and Drug Administration approved minimal invasive therapy for sacral neuromodulation for lower urinary tract dysfunction. Before InterStim implantation, a trial with the appropriate screening tests is required to determine patient therapy eligibility. There are two different techniques for patient screening: percutaneous nerve evaluation (PNE) test and staged test. Few studies have reported success and failure rates for each technique. However, test sensitivity and predictive values of either test have not been studied. The aim of our study was to determine the sensitivity and specificity of each test and to establish a decision algorithm for the most appropriate testing method to be used as a screening test. METHODS: This cross sectional study was conducted from August 2009 to February 2012 and included patients with lower urinary tract dysfunction who participated in the stimulation test trial. Patients underwent PNE as the first stimulation test, while those who encountered technical difficulty during PNE or electrode migration underwent staged testing. RESULTS: A total of 213 patients, including 172 female and 41 male subjects, underwent PNE. The patients' diagnoses included refractory overactive bladder (47.9%), nonobstructive urinary retention (29.6%), and frequency urgency syndrome (22.1%). A total of 202 patients were screened with PNE and 10 patients with staged testing. Overall sensitivity of PNE was 87.3%, and it was 90% for staged test. PNE specificity was 98.5% as compared to 92.9% for staged test. Positive and negative predictive values for PNE were 99% and 82.1% and for staged test were 90% and 92.9%, respectively. CONCLUSIONS: PNE test has high specificity and positive predictive value. We recommend PNE, a simple office-based, less expensive procedure as the first option for screening. PMID- 27706007 TI - Association Between Overactive Bladder and Polyneuropathy in Diabetic Patients. AB - PURPOSE: Diabetes mellitus (DM) is a chronic metabolic disorder that often leads to complications. We aimed to correlate two complications of DM, polyneuropathy and hyperactive bladder syndrome, using noninvasive measures, such as screening tests. METHODS: We included 80 female and 40 male type 2 diabetic patients in this prospective study. Diabetic polyneuropathy evaluations were conducted using the Douleur Neuropathique 4 Questions (DN4), and overactive bladder (OAB) evaluations were performed using the Overactive Bladder Questionnaire (OAB-V8). The patients were also evaluated for retinopathy and nephropathy. The diabetic male and female patients with or without OAB were chosen and compared for microvascular complications (polyneuropathy, retinopathy, and nephropathy). RESULTS: There were no significant correlations between OAB and retinopathy as well as between OAB and nephropathy among diabetic patients (female patients, P>0.05; male patients, P>0.05 ). However, the patients with OAB were significantly more likely to develop polyneuropathy (female patients, P<0.05; male patients, P<0.05). CONCLUSIONS: In diabetic patients, OAB and diabetic peripheral neuropathy are significantly correlated. These correlations were demonstrated using short, understandable, valid, and reliable disease-specific tests without invasive measures. Using these screening tests, both neurologists and urologists can easily diagnose these complications. PMID- 27706008 TI - Melatonin's Effect on the Efficacy of Desmopressin in the Treatment of Enuresis. AB - PURPOSE: This study aims to evaluate and compare the efficacy of exogenous melatonin associated with desmopressin (dDAVP) and dietary recommendations. METHODS: A total of 189 patients were enrolled from the Service of Pediatrics, Campus Bio-Medico University Hospital of Rome, from January 2013 to June 2015. Of the 189 original patients, 153 children, aged between 5 and 14 years (mean age, 8.7 years) were included in the study. After clinical evaluation and a 3-month period of observation without treatment, children were assigned to receive treatment in one of 3 groups: group 1, dDAVP at a dose of 120 mcg a day (Minirin); group 2, dDAVP at a dose of 120 mcg and dietary recommendations; or group 3, dDAVP at a dose of 120 mcg, dietary recommendations, and melatonin at a dose of 1 mg a day (Melamil plus). Each patient was treated for 3 months. RESULTS: After the 3 months of therapy, a desiderable response was achieved in 30 of 51 patients (58.82%) treated with dDAVP, 35 of 53 patients (66.04%) treated with dDAVP and dietary recommendations, and 35 of 49 patients (71.43%) treated with dDAVP, dietary recommendations, and melatonin. CONCLUSIONS: Although not statistically significant, the results show that the association between dDAVP treatment with dietary recommendations and melatonin could be considered a safe and effective treatment of NE. Considering that the statistically insignificant results might be due to the small sample size, the study will be continued to increase the number of subjects. PMID- 27706009 TI - Social, Economic, and Medical Factors Associated With Solifenacin Therapy Compliance Among Workers Who Suffer From Lower Urinary Tract Symptoms. AB - PURPOSE: The prevalence of hyperactive-type lower urinary tract symptoms is 45.2%, with shares of overactive bladder (OAB) and urge incontinence (UI) symptoms of 10.7% and 8.2%, respectively. We investigated the possible impact of a wide range of social, economic, and medical factors on compliance with solifenacin treatment in the working population. METHODS: Social, economic, and medical factors as well as the Overactive Bladder questionnaire - the OAB-q Short Form (OAB-q SF), bladder diaries, and uroflowmetry of 1,038 people who were administered solifenacin for a year were gathered from employer documentation. RESULTS: Among the subjects, 32% maintained their compliance with solifenacin treatment throughout the year. Only 65% of the patients had compliance exceeding 80%, and 17% of patients had compliance of >=50%, yet less than 80% were still taking solifenacin 12 months after the beginning of this experiment. Working people whose compliance level was, at least, 80% had reliably higher (P<=0.01) average age, annual salary, and treatment efficacy, and a greater treatment satisfaction level, as well as a lack of satisfaction with other antimuscarinic treatments and higher rate of urge UI diagnosis. The same cohort also featured a lower level (P<=0.01) of caffeine abuse and lower share of salary spent purchasing solifenacin. CONCLUSIONS: This study has shown that compliance with solifenacin treatment is associated with a number of significant medical, social, and economic factors. The medical factors included the type of urination disorder, severity of incontinence symptoms, presence of side effects, treatment efficacy and patients' satisfaction with it, and experience using other antimuscarinic treatments. Among the social and economic factors, those with the strongest correlation to compliance were patient age, employment in medicine and education, annual income level, percentage of solifenacin purchase expenditures, and caffeine abuse. Factors with a weaker, but still significant, association were gender, employment in the transportation industry, and monthly income level. PMID- 27706011 TI - Diagnostic Tool for Assessing Overactive Bladder Symptoms: Could the International Prostate Symptom Storage Subscore Replace the Overactive Bladder Symptom Score? AB - PURPOSE: The goal of this study was to compare the International Prostate Symptom Storage Subscore (IPSS-s) and the overactive bladder symptom score (OABSS) as tools for assessing the symptoms of overactive bladder (OAB). METHODS: A cross sectional study was conducted of a sample of 1,341 patients aged 50 years and older with lower urinary tract complaints who had undergone a medical examination at one of several centers. For each patient, we reviewed the International Prostate Symptom Score and the OABSS. The patients were divided into 2 groups according to their IPSS-s result (group 1, score >=6; group 2, score<6) and into another 2 groups according to their OABSS diagnosis (group 3, OAB patients; group 4, non-OAB patients). We determined whether the OABSS varied to a statistically significant extent between groups 1 and 2. Furthermore, we evaluated the correlation of IPSS-s severity with the OABSS results in group 3, and the OAB diagnosis rate was compared between groups 1 and 2. RESULTS: In groups 1 and 2, the OABSS results were not found to vary to a statistically significant extent (P=0.326). In group 3, no significant correlation was found between IPSS-s severity and the OABSS results (P=0.385). In the prevalence analysis, no statistically significant difference was found among the groups, and the receiver operating characteristic curve showed an area under the curve of 0.474. CONCLUSIONS: The results of this cross-sectional analysis suggest that the IPSS-s and the OABSS are not significantly correlated. Although both scores are used to measure OAB symptoms, the simultaneous use of IPSS-s and OABSS is not warranted. PMID- 27706010 TI - Foreign Bodies in the Urinary Bladder and Their Management: A Single-Centre Experience From North India. AB - PURPOSE: This study was performed to characterise the nature, clinical presentation, mode of insertion, and management of intravesical foreign bodies in patients treated at our hospital. METHODS: Between January 2008 and December 2014, 49 patients were treated for intravesical foreign bodies at King George Medical University, Lucknow. All records of these patients were retrospectively analysed to characterise the nature of the foreign body, each patient's clinical presentation, the mode of insertion, and how the case was managed. RESULTS: A total of 49 foreign bodies were retrieved from patients' urinary bladders during the study period. The patients ranged in age from 11 to 68 years. Thirty-three patients presented with complaints of haematuria (67.3%), 29 complained of frequency of urination and dysuria (59.1%), and 5 patients reported pelvic pain (10.2%). The circumstances of insertion were iatrogenic in 20 cases (40.8%), self insertion in 17 cases (34.6%), sexual abuse in 4 cases (8.1%), migration from another organ in 4 cases (8.1%), and assault in 4 cases (8.1%). Of the foreign bodies, 33 (67.3%) were retrieved by cystoscopy, while transurethral cystolitholapaxy was required in 10 patients (20.4%), percutaneous suprapubic cystolitholapaxy was performed in 4 patients (8.1%), and holmium laser lithotripsy was performed in 2 patients (4.08%). CONCLUSIONS: Foreign bodies should always be included in the differential diagnosis when evaluating a patient who presents with chronic lower urinary tract symptoms. A large percentage of foreign bodies can be retrieved using endoscopic techniques. Open surgical removal may be performed in cases where endoscopic techniques are unsuitable or have failed. PMID- 27706012 TI - Sacral Neuromodulation in Patients With a Cardiac Pacemaker. AB - The objective of this study was to describe our experience using sacral neuromodulation to treat urinary urgency, frequency, urge incontinence, and chronic urinary retention in patients with cardiac pacemakers. With the increasingly widespread use of InterStim for bladder function restoration, we are seeing more complex patients with multiple comorbidities, including cardiac conditions. Herein, we report 3 cases of individuals with cardiac pacemakers who underwent InterStim implantation to treat urinary conditions. This study is a case series of 3 patients with cardiac pacemakers who underwent sacral neuromodulation to treat refractory voiding dysfunction. The initial patient screening for InterStim therapy involved percutaneous nerve evaluation (PNE), in which a temporary untined lead wire was placed through the S3 foramen. Patients who did not respond to PNE proceeded to a staged implant. All patients in this study had a greater than 50% improvement of their urinary symptoms during the initial trial and underwent placement of the InterStim implantable pulse generator (IPG). Postoperative programming was done under electrocardiogram monitoring by a cardiologist. No interference was observed between the Inter- Stim IPG and the cardiac pacemaker. In this group of patients, sacral neuromodulation in the presence of a cardiac pacemaker appears to have been safe. PMID- 27706014 TI - Typical Value Ranges and Typical Signal Patterns in the Initial Cough in Patients With Neurogenic Bladder: Quality Control in Urodynamic Studies. AB - PURPOSE: The goal of this study was to establish typical value ranges (TVRs) and to analyze typical signal patterns (TSPs) of the initial cough (cough before bladder filling) for quality control in urodynamic studies. METHODS: A total of 539 urodynamic traces from patients with neurogenic bladder obtained over the course of a year were retrospectively reviewed. The TVRs for cough amplitude in measurements of the intravesical pressure (Pves), abdominal pressure (Pabd), and detrusor pressure (Pdet) during the initial cough were established. We used the 95% range as a reference range for all parameters. Cough spikes in Pdet were described and classified, and the reasons for different patterns of cough spikes were established. The quality of all the cystometry traces was checked, and we also present remedial actions for inappropriate cough spikes. RESULTS: The cough amplitudes in the measurements of Pves and Pabd were similar, with 95% of measurements falling within the following ranges: 4-62 cm H2O and 3-70 cm H2O, respectively, in supine position and 9-95 cm H2O and 8-98 cm H2O, respectively, in sitting position. For Pdet, the cough amplitude ranged from -38 to 25 cm H2O in supine position and from -44 to 41 cm H2O in sitting position. The cough spikes for Pdet were classified as follows: type I, Pdet pressure exhibited a minimal change (<5 cm H2O) during the cough; type II, a monophasic spike (>5 cm H2O) was observed for Pdet; and type III, biphasic spikes were observed for Pdet. Type I coughs were found to have more high-quality traces (P<0.01). CONCLUSIONS: TVRs for the initial cough test among neurogenic patients were established in order to provide guidelines for quantitative quality control. The TSPs for the initial cough signal were described, and the presence of a high-quality cough signal may be recommended as a component of quality control in urodynamic measurements. PMID- 27706013 TI - The Early Histological Effects of Intravesical Instillation of Platelet-Rich Plasma in Cystitis Models. AB - PURPOSE: To evaluate the early histological effects of the intravesical instillation of platelet-rich plasma (PRP) in rabbit models of interstitial and hemorrhagic cystitis. METHODS: Thirty-six rabbits were classified into 6 groups: saline (S), S+PRP, hydrochloric acid (HCl), HCl+PRP, cyclophosphamide (CyP), and CyP+PRP. At 48 hours after induction, PRP was prepared and intravesically administered to the S+PRP, HCl+PRP, and CyP+PRP groups. Bladder sections were stained with toluidine blue for mast cell counting and with hematoxylin and eosin for histopathology and mitotic index determination. The proliferation index was determined by proliferating cell nuclear antigen (PCNA) immunolabeling. The nonparametric Mann-Whitney U-test was used for statistical analysis. RESULTS: No abnormalities were observed in the S group, whereas increased interstitial edema and increased average mitotic and proliferation indices were observed in the S+PRP group (P=0.023, P=0.004, and P=0.009, respectively). Intense epithelial loss, hemorrhage, and leukocyte infiltration were detected in the HCl and HCl+PRP groups, whereas a significantly increased average mitotic index was observed in the HCl+PRP group (P=0.002). When compared with its CyP counterpart, a significant reduction in hemorrhage and an increase in leukocyte infiltration and mitotic index were observed in the CyP+PRP group (P=0.006, P=0.038, and P=0.002, respectively). In addition, PCNA staining revealed a significantly increased proliferation index in the HCl+PRP and CyP+PRP groups (P=0.032 and P=0.015, respectively). CONCLUSIONS: The intravesical instillation of PRP increased the mitotic index in the saline and cyclophosphamide groups while decreasing macroscopic bleeding. PMID- 27706015 TI - Translation and Linguistic Validation of the Korean Version of the "Benefit, Satisfaction, and Willingness to Continue" Questionnaire for Patients With Overactive Bladder. AB - PURPOSE: The goal of this study was to develop a Korean version of the Benefit, Satisfaction, and Willingness to Continue (BSW) questionnaire from the original version, with subsequent linguistic validation by Korean patients with overactive bladder who undergo active treatment by a physician. METHODS: Translation and linguistic validation were performed in January 2013. The validation process included permission for translation, forward translation, reconciliation, backward translation, cognitive debriefing, and proofreading. RESULTS: During the forward translation process, the terms or phrases of 'benefit,' 'willingness,' "have you had any benefit?," "taking all things into account" were adjusted to be more appropriate expressions in the Korean language than those used in the original version. During the backward translation process, no changes were made in terms of the sematic equivalence. In the cognitive debriefing session, 5 patients were asked to fill in the answers within 5 minutes; most reported that the translated questions were clear and easy to understand. One patient felt the questions were a little bit difficult to understand; however, the panel decided not to change the expressions because the overall level of comprehension was high and the translated terms were accurate enough to convey the meaning of the original version of the BSW. CONCLUSIONS: The present study showed a successful linguistic validation of the BSW questionnaire. Further studies are needed to assess of the psychometric properties of the BSW. PMID- 27706016 TI - Abnormal Sensory Protein Expression and Urothelial Dysfunction in Ketamine Related Cystitis in Humans. AB - PURPOSE: The aim of this study was to analyze patterns of sensory protein expression and urothelial dysfunction in ketamine-related cystitis (KC) in humans. METHODS: Biopsies of bladder mucosa were performed in 29 KC patients during cystoscopy. Then specimens were analyzed for tryptase, zonula occludens-1 (ZO-1), E-cadherin, and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) with immunofluorescence staining and quantification. In addition, 10 healthy control bladder specimens were analyzed and compared with the KC specimens. Another 16 whole bladder specimens obtained from partial cystectomy were also analyzed for the muscarinic receptors M2 and M3, endothelial nitric oxide synthase (eNOS), inducible nitric oxide synthase (iNOS), beta-3 adrenergic receptors (beta3-ARs), and the P2X3 receptor by western blotting. In addition, 3 normal control bladder specimens were analyzed and compared with the KC specimens. RESULTS: The KC bladder mucosa revealed significantly less expression of ZO-1 and E-cadherin, and greater expression of TUNEL and tryptase activity than the control samples. The expression of M3 and beta3-AR in the KC specimens was significantly greater than in the controls. The expression of iNOS, eNOS, M2, and P2X3 was not significantly different between the KC and control specimens. CONCLUSIONS: The bladder tissue of KC patients revealed significant urothelial dysfunction, which was associated with mast-cell mediated inflammation, increased urothelial cell apoptosis, and increased expression of the M3 and beta3-AR. PMID- 27706017 TI - Application of Virtual, Augmented, and Mixed Reality to Urology. AB - Recent developments in virtual, augmented, and mixed reality have introduced a considerable number of new devices into the consumer market. This momentum is also affecting the medical and health care sector. Although many of the theoretical and practical foundations of virtual reality (VR) were already researched and experienced in the 1980s, the vastly improved features of displays, sensors, interactivity, and computing power currently available in devices offer a new field of applications to the medical sector and also to urology in particular. The purpose of this review article is to review the extent to which VR technology has already influenced certain aspects of medicine, the applications that are currently in use in urology, and the future development trends that could be expected. PMID- 27706018 TI - Controls of Nuclear Factor-Kappa B Signaling Activity by 5'-AMP-Activated Protein Kinase Activation With Examples in Human Bladder Cancer Cells. AB - Generally, both lipopolysaccharide (LPS)- and hypoxia-induced nuclear factor kappa B (NF-kappaB) effects are alleviated through differential posttranslational modification of NF-kappaB phosphorylation after pretreatment with 5'-AMP activated protein kinase (AMPK) activators such as 5'-aminoimidazole-4 carboxamide ribonucleotide (AICAR) or the hypoglycemic agent metformin. We found that AICAR or metformin acts as a regulator of LPS/NF-kappaB-or hypoxia/NF-kappaB mediated cyclooxygenase induction by an AMPK-dependent mechanism with interactions between p65-NF-kappaB phosphorylation and acetylation, including in a human bladder cancer cell line (T24). In summary, we highlighted the regulatory interactions of AMPK activity on NF-kappaB induction, particularly in posttranslational phosphorylation and acetylation of NF-kappaB under inflammatory conditions or hypoxia environment. PMID- 27706019 TI - Antidermatophytic Action of Resorcinol Derivatives: Ultrastructural Evidence of the Activity of Phenylethyl Resorcinol against Microsporum gypseum. AB - In this work, we evaluated the antidermatophytic activities of three resorcinol derivatives that have a history of use in dermo-cosmetic applications to discover molecules with multiple dermatological activities (i.e., multi-target drugs), thereby reducing the cost and time necessary for new drug development. The antidermatophytic activities of the three skin lighteners were evaluated relative to the known antifungal drug fluconazole on nine dermatophytes responsible for the most common dermatomycoses: Microsporum gypseum, Microsporum canis, Trichophyton violaceum, Arthroderma cajetani, Trichophyton mentagrophytes, Epidermophyton floccosum, Nannizzia gypsea, Trichophyton rubrum and Trichophyton tonsurans. Among the three tested resorcinols, only two showed promising properties, with the ability to inhibit the growth of all tested dermatophytes; additionally, the IC50 values of these two resorcinols against the nine dermatophytes confirmed their good antifungal activity, particularly for phenylethyl resorcinol against M. gypseum. Ultrastructural alterations exhibited by the fungus were observed using scanning electron microscopy and transmission electron microscopy and reflected a dose-dependent response to treatment with the activation of defence and self-preservation strategies. PMID- 27706020 TI - Berry Fruit Consumption and Metabolic Syndrome. AB - Metabolic Syndrome is a cluster of risk factors which often includes central obesity, dyslipidemia, insulin resistance, glucose intolerance, hypertension, endothelial dysfunction, as well as a pro-inflammatory, pro-oxidant, and pro thrombotic environment. This leads to a dramatically increased risk of developing type II diabetes mellitus and cardiovascular disease, which is the leading cause of death both in the United States and worldwide. Increasing evidence suggests that berry fruit consumption has a significant potential in the prevention and treatment of most risk factors associated with Metabolic Syndrome and its cardiovascular complications in the human population. This is likely due to the presence of polyphenols with known antioxidant and anti-inflammatory effects, such as anthocyanins and/or phenolic acids. The present review summarizes the findings of recent dietary interventions with berry fruits on human subjects with or at risk of Metabolic Syndrome. It also discusses the potential role of berries as part of a dietary strategy which could greatly reduce the need for pharmacotherapy, associated with potentially deleterious side effects and constituting a considerable financial burden.

PMID- 27706023 TI - How Doth the Little Crocodilian: Analyzing the Influence of Environmental Viscosity on Feeding Performance of Juvenile Alligator mississippiensis. AB - Wetland habitats are used as nursery sites for hatchling and juvenile alligators (Alligator mississippiensis), where they utilize prey from aquatic and terrestrial settings. However, little is known about how viscosity of the medium influences feeding performance. We hypothesized that timing and linear excursion feeding kinematic variables would be different for individuals feeding on prey above the water compared with the same individuals feeding underwater. Individuals were fed immobile fish prey and feeding events were recorded using a high speed video camera. Feeding performance was summarized by analyzing three feeding kinematic variables (maximum gape, maximum gape velocity, duration of feeding bout) and success of strike. Results of a series of paired t-tests indicated no significant difference in kinematic variables between feeding events above water compared with underwater. Similarity in feeding performance could indicate that prey-capture is not altered by environmental viscosity or that feeding behavior can mitigate its influence. Behavioral differences were observed during feeding events with alligators approaching underwater prey having their mouths partially opened versus fully closed when feeding above water. This behavior could be an indication of a strategy used to overcome water viscosity. PMID- 27706022 TI - The Cluster Variation Method: A Primer for Neuroscientists. AB - Effective Brain-Computer Interfaces (BCIs) require that the time-varying activation patterns of 2-D neural ensembles be modelled. The cluster variation method (CVM) offers a means for the characterization of 2-D local pattern distributions. This paper provides neuroscientists and BCI researchers with a CVM tutorial that will help them to understand how the CVM statistical thermodynamics formulation can model 2-D pattern distributions expressing structural and functional dynamics in the brain. The premise is that local-in-time free energy minimization works alongside neural connectivity adaptation, supporting the development and stabilization of consistent stimulus-specific responsive activation patterns. The equilibrium distribution of local patterns, or configuration variables, is defined in terms of a single interaction enthalpy parameter (h) for the case of an equiprobable distribution of bistate (neural/neural ensemble) units. Thus, either one enthalpy parameter (or two, for the case of non-equiprobable distribution) yields equilibrium configuration variable values. Modeling 2-D neural activation distribution patterns with the representational layer of a computational engine, we can thus correlate variational free energy minimization with specific configuration variable distributions. The CVM triplet configuration variables also map well to the notion of a M = 3 functional motif. This paper addresses the special case of an equiprobable unit distribution, for which an analytic solution can be found. PMID- 27706024 TI - Modified Aloe Polysaccharide Restores Chronic Stress-Induced Immunosuppression in Mice. AB - Chronic stress generally experienced in our daily lives; is known to augment disease vulnerability by suppressing the host immune system. In the present study; the effect of modified Aloe polysaccharide (MAP) on chronic stress-induced immunosuppression was studied; this Aloe compound was characterized in our earlier study. Mice were orally administered with MAP for 24 days and exposed to electric foot shock (EFS; duration; 3 min; interval; 10 s; intensity; 2 mA) for 17 days. The stress-related immunosuppression and restorative effect of MAP were then analyzed by measuring various immunological parameters. MAP treatment alleviated lymphoid atrophy and body weight loss. The numbers of lymphocyte subsets were significantly normalized in MAP-treated mice. Oral administration of MAP also restored the proliferative activities of lymphocytes; ovalbumin (OVA) specific T cell proliferation; antibody production; and the cell killing activity of cytotoxic T lymphocytes. In summary; oral administration of MAP ameliorated chronic EFS stress-induced immunosuppression. PMID- 27706025 TI - The Role of PET/CT Molecular Imaging in the Diagnosis of Recurrence and Surveillance of Patients Treated for Non-Small Cell Lung Cancer. AB - Non-small cell lung cancer (NSCLC) is the leading cause of cancer mortality worldwide and its prognosis remains poor. Molecular imaging with 18F-FDG PET/CT can metabolically characterize the nature of lesions as benign or malignant, allowing a better staging at the diagnosis of this kind of patient. This advantage can also be applied in the re-staging due to the suspicion of recurrent disease. Many patients have a recurrence of the disease, including surgically treated patients. In the current context, with new personalized oncological treatments, the surveillance for recurrence and its accurate diagnosis are crucial to improve their survival. In this paper, we revise the current knowledge about the clinical and molecular factors related to the recurrent disease. In the context of new, promising, available personalized treatments, the role of molecular imaging with PET/CT and 18F-FDG and non-18F-FDG radiotracers in the follow-up of NSCLC-treated patients is especially attractive and interesting. PMID- 27706026 TI - Dexmedetomidine-Induced Contraction Involves CPI-17 Phosphorylation in Isolated Rat Aortas. AB - Dexmedetomidine, a highly selective alpha-2 adrenoceptor agonist, produces vasoconstriction, which leads to transiently increased blood pressure. The goal of this study was to investigate specific protein kinases and the associated cellular signal pathways responsible for the increased calcium sensitization induced by dexmedetomidine in isolated rat aortas, with a particular focus on phosphorylation-dependent inhibitory protein of myosin phosphatase (CPI-17). The effect of Y-27632 and chelerythrine on the dexmedetomidine-induced intracellular calcium concentration ([Ca2+]i) and tension were assessed using fura-2-loaded aortic strips. The effects of rauwolscine, Y-27632, chelerythrine, and ML-7 hydrochloride on the dexmedetomidine-induced phosphorylation of CPI-17 or of the 20-kDa regulatory light chain of myosin (MLC20) were investigated in rat aortic vascular smooth muscle cells. The effects of rauwolscine, Y-27632, and chelerythrine on the membrane translocation of Rho-kinase and protein kinase C (PKC) phosphorylation induced by dexmedetomidine were assessed. Y-27632 and chelerythrine each reduced the slopes of the [Ca2+]i-tension curves of dexmedetomidine-induced contraction, and Y-27632 more strongly reduced these slopes than did chelerythrine. Rauwolscine, Y-27632, chelerythrine, and ML-7 hydrochloride attenuated the dexmedetomidine-induced phosphorylation of CPI-17 and MLC20. Taken together, these results suggest that dexmedetomidine-induced contraction involves calcium sensitization, which appears to be mediated by CPI 17 phosphorylation via Rho-kinase or PKC. PMID- 27706027 TI - The Role of Family in a Dietary Risk Reduction Intervention for Cardiovascular Disease. AB - Diet is an essential strategy for the prevention of primary and secondary cardiovascular disease (CVD) events. The objectives were to examine: how families at increased risk of CVD perceived personal risk, their motivations to make dietary changes, their understanding of diet, and the influence of other family members. Individuals (>18 years) who completed an Australian family-based CVD risk reduction program were invited to a semi-structured telephone interview. Responses were recorded, transcribed verbatim and analysed using a systematic deductive approach with coding derived from key concepts developed as part of the interview structure. Seventeen participants from eight families were interviewed (aged 18-70 years, 47% male, five with CVD diagnosis). Key themes indicated both intrinsic and extrinsic motivations to improve heart health, variations in risk perception, recognition of the role diet plays in heart health, and the extent of family influences on eating patterns. Discrepancies between perceived and actual CVD risk perception impacted on perceived "need" to modify current dietary patterns towards heart health recommendations. Therefore, strategies not reliant on risk perception are needed to engage those with low risk perception. This could involve identifying and accessing the family "ringleader" to influence involvement and capitalising on personal accountability to other family members. PMID- 27706029 TI - Analysis of Aggregation Delay for Multisource Sensor Data with On-Off Traffic Pattern in Wireless Body Area Networks. AB - Data aggregation plays an important role to improve the transmission efficiency in wireless body area networks (WBANs); however, it inherently induces additional aggregation delay. Therefore, the effect of packet aggregation on WBAN applications, which are vulnerable to delay, must be analyzed rigorously. In this paper, we analyze the packet aggregation delay for multisource sensor data with an on-off traffic pattern in WBANs. Considering two operational parameters of the aggregation threshold and aggregation timer, we calculate the probability that a packet aggregation occurs during a unit time and then derive the average aggregation delay in closed-form. The analysis results show that the aggregation delay increases as the aggregation timer or aggregation threshold increases, but is bounded below a certain level according to the number of active sensors and their on-off traffic attribute. This implies that the data aggregation technique can maximize the transmission efficiency while satisfying a given delay requirement in the WBAN system. PMID- 27706028 TI - Lycopene, Lutein and Zeaxanthin May Reduce Faecal Blood, Mucus and Pus but not Abdominal Pain in Individuals with Ulcerative Colitis. AB - BACKGROUND: The main symptom of ulcerative colitis is diarrhoea, which is often accompanied by painful tenesmus and faecal blood and mucus. It sometimes co occurs with abdominal pain, fever, feeling of fatigue, loss of appetite and weight loss. Some dietary factors have been indicated as important in the treatment of ulcerative colitis. The aim of the study was to analyse the association between retinoid intake (total vitamin A, retinol, beta-carotene, alpha-carotene, beta-cryptoxanthin, lycopene, lutein and zeaxanthin) and ulcerative colitis symptoms (abdominal pain, faecal blood, faecal mucus, faecal pus) in individuals with ulcerative colitis in remission. METHODS: Assessment of diet was based on self-reported data from each patient's dietary records taken over a period of three typical, random days (2 weekdays and 1 day of the weekend). RESULTS: A total of 56 individuals with ulcerative colitis in remission (19 males and 37 females) were recruited for the study. One in every four individuals with ulcerative colitis in remission was characterised as having inadequate vitamin A intake. Higher lycopene, lutein and zeaxanthin intakes in individuals with ulcerative colitis in remission were associated with lower faecal blood, mucus and pus but not with lower incidence of abdominal pain. Higher carotene intake in individuals with ulcerative colitis in remission may contribute to higher incidence of faecal mucus. CONCLUSIONS: Optimising intake of specific retinoids may enhance disease control in individuals with ulcerative colitis. Prospective studies, including patient reported and objective outcomes, are required to confirm this. PMID- 27706030 TI - Metabolomics and Cheminformatics Analysis of Antifungal Function of Plant Metabolites. AB - Fusarium head blight (FHB), primarily caused by Fusarium graminearum, is a devastating disease of wheat. Partial resistance to FHB of several wheat cultivars includes specific metabolic responses to inoculation. Previously published studies have determined major metabolic changes induced by pathogens in resistant and susceptible plants. Functionality of the majority of these metabolites in resistance remains unknown. In this work we have made a compilation of all metabolites determined as selectively accumulated following FHB inoculation in resistant plants. Characteristics, as well as possible functions and targets of these metabolites, are investigated using cheminformatics approaches with focus on the likelihood of these metabolites acting as drug-like molecules against fungal pathogens. Results of computational analyses of binding properties of several representative metabolites to homology models of fungal proteins are presented. Theoretical analysis highlights the possibility for strong inhibitory activity of several metabolites against some major proteins in Fusarium graminearum, such as carbonic anhydrases and cytochrome P450s. Activity of several of these compounds has been experimentally confirmed in fungal growth inhibition assays. Analysis of anti-fungal properties of plant metabolites can lead to the development of more resistant wheat varieties while showing novel application of cheminformatics approaches in the analysis of plant/pathogen interactions.

AB - Strongyloidiasis is an underestimated disease caused by the soil-transmitted parasite of the genus Strongyloides. It is prevalent in socioeconomically disadvantaged communities and it is estimated that global infection could be as high as 370 million people. This paper explores current methods of strongyloidiasis treatment, which rely on administration of anthelminthic drugs. However these drugs cannot prevent reinfection and drug resistance has already been observed in veterinary models. This highlights the need for a combined approach for controlling Strongyloides that includes both clinical treatment and environmental control methods. Currently, nematicides are widely used to control plant parasites. The review suggests that due to the species' similarity and similar modes of action, these nematicides could also be used to control animal and human parasitic nematodes in the environment.

AB - In this work we directly synthesized molybdenum disulfide (MoS2) nanosheets on carbon nanotube film (MoS2@CNT) via a two-step chemical vapor deposition method (CVD). By etching the obtained MoS2@CNT into 10% wt HNO3, the morphology of MoS2 decorated on CNT bundles was modulated, resulting in more catalytic active MoS2 edges being exposed for significantly enhanced electrochemical performance. Our results revealed that an 8 h acid etching sample exhibited the best performance for the oxygen evolution reaction, i.e., the current density reached 10 mA/cm2 under 375 mV over-potential, and the tafel slope was as low as 94 mV/dec. The enhanced behavior was mainly originated from the more catalytic sites in MoS2 induced by the acid etching treatment and the higher conductivity from the supporting CNT films. Our study provides a new route to produce two-dimensional layers on CNT films with tunable morphology, and thus may open a window for exploring its promising applications in the fields of catalytic-, electronic-, and electrochemical-related fields. PMID- 27706034 TI - Neurodegenerative Diseases: Might Citrus Flavonoids Play a Protective Role? AB - Neurodegenerative diseases (ND) result from the gradual and progressive degeneration of the structure and function of the central nervous system or the peripheral nervous system or both. They are characterized by deterioration of neurons and/or myelin sheath, disruption of sensory information transmission and loss of movement control. There is no effective treatment for ND, and the drugs currently marketed are symptom-oriented, albeit with several side effects. Within the past decades, several natural remedies have gained attention as potential neuroprotective drugs. Moreover, an increasing number of studies have suggested that dietary intake of vegetables and fruits can prevent or delay the onset of ND. These properties are mainly due to the presence of polyphenols, an important group of phytochemicals that are abundantly present in fruits, vegetables, cereals and beverages. The main class of polyphenols is flavonoids, abundant in Citrus fruits. Our review is an overview on the scientific literature concerning the neuroprotective effects of the Citrus flavonoids in the prevention or treatment of ND. This review may be used as scientific basis for the development of nutraceuticals, food supplements or complementary and alternative drugs to maintain and improve the neurophysiological status. PMID- 27706032 TI - Plasma Carotenoids, Tocopherols, and Retinol in the Age-Stratified (35-74 Years) General Population: A Cross-Sectional Study in Six European Countries. AB - Blood micronutrient status may change with age. We analyzed plasma carotenoids, alpha-/gamma-tocopherol, and retinol and their associations with age, demographic characteristics, and dietary habits (assessed by a short food frequency questionnaire) in a cross-sectional study of 2118 women and men (age-stratified from 35 to 74 years) of the general population from six European countries. Higher age was associated with lower lycopene and alpha-/beta-carotene and higher beta-cryptoxanthin, lutein, zeaxanthin, alpha-/gamma-tocopherol, and retinol levels. Significant correlations with age were observed for lycopene (r = 0.248), alpha-tocopherol (r = 0.208), alpha-carotene (r = -0.112), and beta cryptoxanthin (r = 0.125; all p < 0.001). Age was inversely associated with lycopene (-6.5% per five-year age increase) and this association remained in the multiple regression model with the significant predictors (covariables) being country, season, cholesterol, gender, smoking status, body mass index (BMI (kg/m2)), and dietary habits. The positive association of alpha-tocopherol with age remained when all covariates including cholesterol and use of vitamin supplements were included (1.7% vs. 2.4% per five-year age increase). The association of higher beta-cryptoxanthin with higher age was no longer statistically significant after adjustment for fruit consumption, whereas the inverse association of alpha-carotene with age remained in the fully adjusted multivariable model (-4.8% vs. -3.8% per five-year age increase). We conclude from our study that age is an independent predictor of plasma lycopene, alpha tocopherol, and alpha-carotene. PMID- 27706036 TI - Synthesis of a 1-Aryl-2,2-chlorosilyl(phospha)silene Coordinated by an N Heterocyclic Carbene. AB - Phosphasilenes, P=Si doubly bonded compounds, have received considerable attention due to their unique physical and chemical properties. We report on the synthesis and structure of a chlorophosphasilene coordinated by an N-heterocyclic carbene (NHC), which has the potential of functionalization at the Si-Cl moiety. Treatment of a silylphosphine, ArPH-SiCl2RSi (Ar = bulky aryl group, RSi = Si(SiMe3)3) with two equivalents of Im-Me4 (1,3,4,5-tetramethylimidazol-2 ylidene) afforded the corresponding NHC-coordinated phosphasilene, ArP=SiClRSi(Im Me4) as a stable compound. Bonding properties of the P=Si bond coordinated to an NHC will be discussed on the basis of theoretical calculations. PMID- 27706035 TI - Re-188 Enhances the Inhibitory Effect of Bevacizumab in Non-Small-Cell Lung Cancer. AB - The malignant behaviors of solid tumors such as growth, infiltration and metastasis are mainly nourished by tumor neovascularization. Thus, anti angiogenic therapy is key to controlling tumor progression. Bevacizumab, a humanized anti-vascular endothelial growth factor (VEGF) antibody, plus chemotherapy or biological therapy can prolong survival for cancer patients, but treatment-related mortality is a concern. To improve inhibitory effect and decrease side-effects on non-small-cell lung cancer (NSCLC), we used Re-188, which is a beta emitting radionuclide, directly labeled with bevacizumab for radioimmunotherapy in a human A549 tumor model. Cytotoxic assay data showed that, after 188ReO4- or 188Re-bevacizumab at different concentration for 4 and 24 h, a time- and radioactivity does-dependent reduction in cell viability occurred. Also, an apoptosis assay conformed great apoptosis in the 188Re-bevacizumab group compared with controls and other treatment groups. In vivo, tumor volumes in the 188Re-bevacizumab (11.1 MBq/mice) group were not reduced but growth was delayed compared with other groups. Thus, 188Re-bevacizumab enhanced the therapeutic effect of bevacizumab, suggesting a potential therapeutic strategy for NSCLC treatment. PMID- 27706037 TI - Quantitative and Qualitative Analysis of Flavonoids and Phenolic Acids in Snow Chrysanthemum (Coreopsis tinctoria Nutt.) by HPLC-DAD and UPLC-ESI-QTOF-MS. AB - A simple, accurate and reliable high performance liquid chromatography coupled with photodiode array detection (HPLC-DAD) method was developed and then successfully applied for simultaneous quantitative analysis of eight compounds, including chlorogenic acid (1), (R/S)-flavanomarein (2), butin-7-O-beta-d glucopyranoside (3), isookanin (4), taxifolin (5), 5,7,3',5' tetrahydroxyflavanone-7-O-beta-d-glucopyranoside (6), marein (7) and okanin (8), in 23 batches of snow chrysanthemum of different seed provenance and from various habitats. The results showed total contents of the eight compounds in the samples with seed provenance from Keliyang (Xinjiang, China), are higher than in samples from the other five provenances by 52.47%, 15.53%, 19.78%, 21.17% and 5.06%, respectively, which demonstrated that provenance has a great influence on the constituents in snow chrysanthemum. Meanwhile, an ultra performance liquid chromatography coupled with electrospray ionization and quadrupole time-of-flight mass spectrometry (UPLC-ESI-QTOF-MS) was also employed to rapidly separate and identify flavonoids and phenolic acids in snow chrysanthemum from Keliyang. As a result, a total of 30 constituents, including 26 flavonoids and four phenolic acids, were identified or tentatively identified based on the exact mass information, the fragmentation characteristics, and retention times of eight reference standards. This work may provide an efficient approach to comprehensively evaluate the quality of snow chrysanthemum. PMID- 27706039 TI - A Missile-Borne Angular Velocity Sensor Based on Triaxial Electromagnetic Induction Coils. AB - Aiming to solve the problem of the limited measuring range for angular motion parameters of high-speed rotating projectiles in the field of guidance and control, a self-adaptive measurement method for angular motion parameters based on the electromagnetic induction principle is proposed. First, a framework with type bent "I-shape" is used to design triaxial coils in a mutually orthogonal way. Under the condition of high rotational speed of a projectile, the induction signal of the projectile moving across a geomagnetic field is acquired by using coils. Second, the frequency of the pulse signal is adjusted self-adaptively. Angular velocity and angular displacement are calculated in the form of periodic pulse counting and pulse accumulation, respectively. Finally, on the basis of that principle prototype of the sensor is researched and developed, performance of measuring angular motion parameters are tested on the sensor by semi-physical and physical simulation experiments, respectively. Experimental results demonstrate that the sensor has a wide measuring range of angular velocity from 1 rps to 100 rps with a measurement error of less than 0.3%, and the angular displacement measurement error is lower than 0.2 degrees . The proposed method satisfies measurement requirements for high-speed rotating projectiles with an extremely high dynamic range of rotational speed and high precision, and has definite value to engineering applications in the fields of attitude determination and geomagnetic navigation. PMID- 27706038 TI - Dimerization of the Vacuolar Receptors AtRMR1 and -2 from Arabidopsis thaliana Contributes to Their Localization in the trans-Golgi Network. AB - In Arabidopsis thaliana, different types of vacuolar receptors were discovered. The AtVSR (Vacuolar Sorting Receptor) receptors are well known to be involved in the traffic to lytic vacuole (LV), while few evidences demonstrate the involvement of the receptors from AtRMR family (Receptor Membrane RING-H2) in the traffic to the protein storage vacuole (PSV). In this study we focused on the localization of two members of AtRMR family, AtRMR1 and -2, and on the possible interaction between these two receptors in the plant secretory pathway. Our experiments with agroinfiltrated Nicotiana benthamiana leaves demonstrated that AtRMR1 was localized in the endoplasmic reticulum (ER), while AtRMR2 was targeted to the trans-Golgi network (TGN) due to the presence of a cytosolic 23-amino acid sequence linker. The fusion of this linker to an equivalent position in AtRMR1 targeted this receptor to the TGN, instead of the ER. By using a Bimolecular Fluorescent Complementation (BiFC) technique and experiments of co-localization, we demonstrated that AtRMR2 can make homodimers, and can also interact with AtRMR1 forming heterodimers that locate to the TGN. Such interaction studies strongly suggest that the transmembrane domain and the few amino acids surrounding it, including the sequence linker, are essential for dimerization. These results suggest a new model of AtRMR trafficking and dimerization in the plant secretory pathway. PMID- 27706040 TI - Angiotensin-I Converting Enzyme (ACE) Inhibitory and Anti-Hypertensive Effect of Protein Hydrolysate from Actinopyga lecanora (Sea Cucumber) in Rats. AB - Food protein hydrolysates are known to exhibit angiotensin converting enzyme (ACE) inhibitory properties and can be used as a novel functional food for prevention of hypertension. This study evaluated the ACE inhibitory potentials of Actinopyga lecanora proteolysate (ALP) in vivo. The pre-fed rats with ALP at various doses (200, 400, 800 mg/kg body weight) exhibited a significant (p <= 0.05) suppression effect after inducing hypertension. To determine the optimum effective dose that will produce maximal reduction in blood pressure, ALP at three doses was fed to the rats after inducing hypertension. The results showed that the 800 mg/kg body weight dose significantly reduced blood pressure without noticeable negative physiological effect. In addition, there were no observable changes in the rats' heart rate after oral administration of the ALP. It was concluded that Actinopyga lecanora proteolysate could potentially be used for the development of functional foods and nutraceuticals for prevention and treatment of hypertension. PMID- 27706042 TI - Data-Gathering Scheme Using AUVs in Large-Scale Underwater Sensor Networks: A Multihop Approach. AB - In this paper, we propose a data-gathering scheme for hierarchical underwater sensor networks, where multiple Autonomous Underwater Vehicles (AUVs) are deployed over large-scale coverage areas. The deployed AUVs constitute an intermittently connected multihop network through inter-AUV synchronization (in this paper, synchronization means an interconnection between nodes for communication) for forwarding data to the designated sink. In such a scenario, the performance of the multihop communication depends upon the synchronization among the vehicles. The mobility parameters of the vehicles vary continuously because of the constantly changing underwater currents. The variations in the AUV mobility parameters reduce the inter-AUV synchronization frequency contributing to delays in the multihop communication. The proposed scheme improves the AUV synchronization frequency by permitting neighboring AUVs to share their status information via a pre-selected node called an agent-node at the static layer of the network. We evaluate the proposed scheme in terms of the AUV synchronization frequency, vertical delay (node->AUV), horizontal delay (AUV->AUV), end-to-end delay, and the packet loss ratio. Simulation results show that the proposed scheme significantly reduces the aforementioned delays without the synchronization time-out process employed in conventional works. PMID- 27706041 TI - Controlling Properties and Cytotoxicity of Chitosan Nanocapsules by Chemical Grafting. AB - The tunability of the properties of chitosan-based carriers opens new ways for the application of drugs with low water-stability or high adverse effects. In this work, the combination of a nanoemulsion with a chitosan hydrogel coating and the following poly (ethylene glycol) (PEG) grafting is proven to be a promising strategy to obtain a flexible and versatile nanocarrier with an improved stability. Thanks to chitosan amino groups, a new easy and reproducible method to obtain nanocapsule grafting with PEG has been developed in this work, allowing a very good control and tunability of the properties of nanocapsule surface. Two different PEG densities of coverage are studied and the nanocapsule systems obtained are characterized at all steps of the optimization in terms of diameter, Z potential and surface charge (amino group analysis). Results obtained are compatible with a conformation of PEG molecules laying adsorbed on nanoparticle surface after covalent linking through their amino terminal moiety. An improvement in nanocapsule stability in physiological medium is observed with the highest PEG coverage density obtained. Cytotoxicity tests also demonstrate that grafting with PEG is an effective strategy to modulate the cytotoxicity of developed nanocapsules. Such results indicate the suitability of chitosan as protective coating for future studies oriented toward drug delivery. PMID- 27706043 TI - Compensation of Verdet Constant Temperature Dependence by Crystal Core Temperature Measurement. AB - Compensation of the temperature dependence of the Verdet constant in a polarimetric extrinsic Faraday sensor is of major importance for applying the magneto-optical effect to AC current measurements and magnetic field sensing. This paper presents a method for compensating the temperature effect on the Faraday rotation in a Bi12GeO20 crystal by sensing its optical activity effect on the polarization of a light beam. The method measures the temperature of the same volume of crystal that effects the beam polarization in a magnetic field or current sensing process. This eliminates the effect of temperature difference found in other indirect temperature compensation methods, thus allowing more accurate temperature compensation for the temperature dependence of the Verdet constant. The method does not require additional changes to an existing Delta/Sigma configuration and is thus applicable for improving the performance of existing sensing devices. PMID- 27706044 TI - Detection and Characterization of Circulating Tumor Associated Cells in Metastatic Breast Cancer. AB - The availability of blood-based diagnostic testing using a non-invasive technique holds promise for real-time monitoring of disease progression and treatment selection. Circulating tumor cells (CTCs) have been used as a prognostic biomarker for the metastatic breast cancer (MBC). The molecular characterization of CTCs is fundamental to the phenotypic identification of malignant cells and description of the relevant genetic alterations that may change according to disease progression and therapy resistance. However, the molecular characterization of CTCs remains a challenge because of the rarity and heterogeneity of CTCs and technological difficulties in the enrichment, isolation and molecular characterization of CTCs. In this pilot study, we evaluated circulating tumor associated cells in one blood draw by size exclusion technology and cytological analysis. Among 30 prospectively enrolled MBC patients, CTCs, circulating tumor cell clusters (CTC clusters), CTCs of epithelial-mesenchymal transition (EMT) and cancer associated macrophage-like cells (CAMLs) were detected and analyzed. For molecular characterization of CTCs, size-exclusion method for CTC enrichment was tested in combination with DEPArrayTM technology, which allows the recovery of single CTCs or pools of CTCs as a pure CTC sample for mutation analysis. Genomic mutations of TP53 and ESR1 were analyzed by targeted sequencing on isolated 7 CTCs from a patient with MBC. The results of genomic analysis showed heterozygous TP53 R248W mutation from one single CTC and pools of three CTCs, and homozygous TP53 R248W mutation from one single CTC and pools of two CTCs. Wild-type ESR1 was detected in the same isolated CTCs. The results of this study reveal that size-exclusion method can be used to enrich and identify circulating tumor associated cells, and enriched CTCs were characterized for genetic alterations in MBC patients, respectively. PMID- 27706045 TI - Disease Activity and Conversion into Multiple Sclerosis after Optic Neuritis Is Treated with Erythropoietin. AB - Changes in cerebral lesion load by magnetic resonance imaging (MRI) in patients from a double-blind, placebo-controlled, phase II study on erythropoietin in clinically isolated optic neuritis (ClinicalTrials.gov, NCT00355095) were analyzed. Therefore, patients with acute optic neuritis were assigned to receive either 33,000 IU of recombinant human erythropoietin (IV) daily for three days, or a placebo, as an add-on to methylprednisolone. Of 35 patients, we investigated changes in cerebral lesion load in MRIs obtained at baseline and at weeks 4, 8, and 16. In 5 of the 35 patients, we found conversion into multiple sclerosis (MS) based on MRI progression only. These five patients had received the placebo. Another five patients showed MRI progression together with relapses. Three of these patients had received erythropoietin, and two the placebo. Yet, analyzing the change in absolute numbers of periventricular, juxtacortical, and infratentorial lesions including gadolinium-enhancing lesions, there were no significant differences between the groups. Although effective in terms of retinal nerve fiber layer protection, erythropoietin treatment of acute isolated optic neuritis did not influence further evolution of MRI lesions in the brain when comparing absolute numbers. However, early conversion from clinically isolated syndrome to MS assessed by MRI activity seemed to occur more frequently in the placebo-treated group. PMID- 27706046 TI - Internet-Supported Physical Exercise Training for Persons with Multiple Sclerosis A Randomised, Controlled Study. AB - Physical exercise is effective in improving functional outcomes in persons with multiple sclerosis (pwMS). We evaluated the feasibility and effectiveness of internet-based exercise training (e-training) for pwMS on health-related quality of life (HrQoL). Secondary outcomes were muscle strength, aerobic capacity, lung function, physical activity, and fatigue. This is a randomised, controlled trial with a wait-list control group. Data were collected at baseline, after three and six months, and analysed using a hybrid linear model. One-hundred twenty-six pwMS participated in the home-based aerobic (1*/week) and strength training (2*/week) intervention that was supervised and documented via an internet-platform. The intervention group received e-training for six months, and the control group received e-training after a three months waiting period. Significant differences between the groups were only observed for muscle strength (knee flexion (effect size ES = 0.3, p = 0.003), knee extension (ES = 0.24, p = 0.015)), peak expiratory flow (ES = 0.2, p = 0.039), and sports activity (ES = 0.33, p = 0.001) after three months. E-training had no effect on HrQoL but did on muscle strength, lung function, and physical activity. It is a promising and feasible approach to facilitate large-scale, yet individual, training support. PMID- 27706048 TI - Assessment of Data Fusion Algorithms for Earth Observation Change Detection Processes. AB - In this work a parametric multi-sensor Bayesian data fusion approach and a Support Vector Machine (SVM) are used for a Change Detection problem. For this purpose two sets of SPOT5-PAN images have been used, which are in turn used for Change Detection Indices (CDIs) calculation. For minimizing radiometric differences, a methodology based on zonal "invariant features" is suggested. The choice of one or the other CDI for a change detection process is a subjective task as each CDI is probably more or less sensitive to certain types of changes. Likewise, this idea might be employed to create and improve a "change map", which can be accomplished by means of the CDI's informational content. For this purpose, information metrics such as the Shannon Entropy and "Specific Information" have been used to weight the changes and no-changes categories contained in a certain CDI and thus introduced in the Bayesian information fusion algorithm. Furthermore, the parameters of the probability density functions (pdf's) that best fit the involved categories have also been estimated. Conversely, these considerations are not necessary for mapping procedures based on the discriminant functions of a SVM. This work has confirmed the capabilities of probabilistic information fusion procedure under these circumstances. PMID- 27706047 TI - Implications of Hypoxia in Breast Cancer Metastasis to Bone. AB - Most solid tumors contain regions of hypoxia in which increased cell proliferation promotes increased oxygen consumption and the condition is further exacerbated as cancer cells become localized far from a functional blood vessel, further decreasing the oxygen supply. An important mechanism that promotes cell adaptation to hypoxic conditions is the expression of hypoxia-inducible factors (HIFs). Hypoxia-inducible factors transcriptionally regulate many genes involved in the invasion and metastasis of breast cancer cells. Patients, whose primary tumor biopsies show high HIF expression levels, have a greater risk of metastasis. The current review will highlight the potential role of hypoxia in breast cancer metastasis to the bone by considering the regulation of many steps in the metastatic process that include invasion, migration, margination and extravasation, as well as homing signals and regulation of the bone microenvironment. PMID- 27706051 TI - Optimization of Sample Points for Monitoring Arable Land Quality by Simulated Annealing while Considering Spatial Variations. AB - With China's rapid economic development, the reduction in arable land has emerged as one of the most prominent problems in the nation. The long-term dynamic monitoring of arable land quality is important for protecting arable land resources. An efficient practice is to select optimal sample points while obtaining accurate predictions. To this end, the selection of effective points from a dense set of soil sample points is an urgent problem. In this study, data were collected from Donghai County, Jiangsu Province, China. The number and layout of soil sample points are optimized by considering the spatial variations in soil properties and by using an improved simulated annealing (SA) algorithm. The conclusions are as follows: (1) Optimization results in the retention of more sample points in the moderate- and high-variation partitions of the study area; (2) The number of optimal sample points obtained with the improved SA algorithm is markedly reduced, while the accuracy of the predicted soil properties is improved by approximately 5% compared with the raw data; (3) With regard to the monitoring of arable land quality, a dense distribution of sample points is needed to monitor the granularity. PMID- 27706050 TI - Universal Stress Proteins as New Targets for Environmental and Therapeutic Interventions of Schistosomiasis. AB - In spite of various control measures and eradication methods that have been in progress, schistosomiasis still prevails as one of the most prevalent debilitating parasitic diseases, typically affecting the poor and the underprivileged that are predominantly concentrated in sub-Saharan Africa. The parasitic schistosome blood fluke responsible for causing the disease completes its complex developmental cycle in two hosts: humans and freshwater snails, where they physically undergo gross modifications to endure the different conditions associated with each host. Just like any other organism, the worm possesses mechanisms that help them respond to environmental insults. It has been hypothesized that a special class of proteins known as Universal Stress Proteins (USPs) are up-regulated during sudden environmental changes, thus assisting the worm to tolerate the unfavourable conditions associated with its developmental cycle. The position of praziquantel as the drug of choice against all schistosome infections has been deemed vulnerable due to mounting concerns over drug pressure and so the need for alternative treatment is now a matter of urgency. Therefore, this review seeks to explore the associations and possible roles of USPs in schistosomiasis as well as the functioning of these proteins in the schistosomulae stage in order to develop new therapeutic interventions against this disease. PMID- 27706049 TI - Structural and Functional Elucidation of Peptide Ts11 Shows Evidence of a Novel Subfamily of Scorpion Venom Toxins. AB - To date, several families of peptide toxins specifically interacting with ion channels in scorpion venom have been described. One of these families comprise peptide toxins (called KTxs), known to modulate potassium channels. Thus far, 202 KTxs have been reported, belonging to several subfamilies of KTxs (called alpha, beta, gamma, kappa, delta, and lambda-KTxs). Here we report on a previously described orphan toxin from Tityus serrulatus venom, named Ts11. We carried out an in-depth structure-function analysis combining 3D structure elucidation of Ts11 and electrophysiological characterization of the toxin. The Ts11 structure is highlighted by an Inhibitor Cystine Knot (ICK) type scaffold, completely devoid of the classical secondary structure elements (alpha-helix and/or beta strand). This has, to the best of our knowledge, never been described before for scorpion toxins and therefore represents a novel, 6th type of structural fold for these scorpion peptides. On the basis of their preferred interaction with voltage gated K channels, as compared to all the other targets tested, it can be postulated that Ts11 is the first member of a new subfamily, designated as epsilon-KTx. PMID- 27706053 TI - Molecular Electron Density Theory: A Modern View of Reactivity in Organic Chemistry. AB - A new theory for the study of the reactivity in Organic Chemistry, named Molecular Electron Density Theory (MEDT), is proposed herein. MEDT is based on the idea that while the electron density distribution at the ground state is responsible for physical and chemical molecular properties, as proposed by the Density Functional Theory (DFT), the capability for changes in electron density is responsible for molecular reactivity. Within MEDT, the reactivity in Organic Chemistry is studied through a rigorous quantum chemical analysis of the changes of the electron density as well as the energies associated with these changes along the reaction path in order to understand experimental outcomes. Studies performed using MEDT allow establishing a modern rationalisation and to gain insight into molecular mechanisms and reactivity in Organic Chemistry. PMID- 27706052 TI - Investigation of Self-Assembly Processes for Chitosan-Based Coagulant-Flocculant Systems: A Mini-Review. AB - The presence of contaminants in wastewater poses significant challenges to water treatment processes and environmental remediation. The use of coagulation flocculation represents a facile and efficient way of removing charged particles from water. The formation of stable colloidal flocs is necessary for floc aggregation and, hence, their subsequent removal. Aggregation occurs when these flocs form extended networks through the self-assembly of polyelectrolytes, such as the amine-based polysaccharide (chitosan), which form polymer "bridges" in a floc network. The aim of this overview is to evaluate how the self-assembly process of chitosan and its derivatives is influenced by factors related to the morphology of chitosan (flocculant) and the role of the solution conditions in the flocculation properties of chitosan and its modified forms. Chitosan has been used alone or in conjunction with a salt, such as aluminum sulphate, as an aid for the removal of various waterborne contaminants. Modified chitosan relates to grafted anionic or cationic groups onto the C-6 hydroxyl group or the amine group at C-2 on the glucosamine monomer of chitosan. By varying the parameters, such as molecular weight and the degree of deacetylation of chitosan, pH, reaction and settling time, dosage and temperature, self-assembly can be further investigated. This mini-review places an emphasis on the molecular-level details of the flocculation and the self-assembly processes for the marine-based biopolymer, chitosan. PMID- 27706054 TI - Real-Time Estimation of Satellite-Derived PM2.5 Based on a Semi-Physical Geographically Weighted Regression Model. AB - The real-time estimation of ambient particulate matter with diameter no greater than 2.5 MUm (PM2.5) is currently quite limited in China. A semi-physical geographically weighted regression (GWR) model was adopted to estimate PM2.5 mass concentrations at national scale using the Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Aerosol Optical Depth product fused by the Dark Target (DT) and Deep Blue (DB) algorithms, combined with meteorological parameters. The fitting results could explain over 80% of the variability in the corresponding PM2.5 mass concentrations, and the estimation tends to overestimate when measurement is low and tends to underestimate when measurement is high. Based on World Health Organization standards, results indicate that most regions in China suffered severe PM2.5 pollution during winter. Seasonal average mass concentrations of PM2.5 predicted by the model indicate that residential regions, namely Jing-Jin-Ji Region and Central China, were faced with challenge from fine particles. Moreover, estimation deviation caused primarily by the spatially uneven distribution of monitoring sites and the changes of elevation in a relatively small region has been discussed. In summary, real-time PM2.5 was estimated effectively by the satellite-based semi-physical GWR model, and the results could provide reasonable references for assessing health impacts and offer guidance on air quality management in China. PMID- 27706055 TI - A Set of 20 New SSR Markers Developed and Evaluated in Mandevilla Lindl. AB - Mandevilla is an ornamental crop with a bright future worldwide because of its high commercial acceptance and added value. However, as with most ornamental species, there are few molecular tools to support cultivar breeding and innovation. In this work, we report the development and analysis of 20 new Simple Sequence Repeat (SSR) markers in Mandevilla. Microsatellites were isolated from two enriched small-insert genomic libraries of Mandevilla * amabilis. The diversity parameters estimated after their amplification in a group of 11 commercial genotypes illustrate the effect of two opposite drifts: the high relatedness of cultivars belonging to the same commercial group and the high divergence of other cultivars, especially M. * amabilis. Based on their different band patterns, six genotypes were uniquely distinguished, and two groups of sport mutations remained undistinguishable. The amplification of the SSRs in three wild species suggested the existence of unexploited diversity available to be introgressed into the commercial pool. This is the first report of available microsatellites in Mandevilla. The development process has provided some clues concerning the genome structure of the species, and the SSRs obtained will help to create new products and to protect existing and upcoming plant innovations. PMID- 27706056 TI - Non-Obese Diabetes and Its Associated Factors in an Underdeveloped Area of South China, Guangxi. AB - BACKGROUND: Little research has been conducted on the prevalence of diabetes mellitus in underdeveloped areas in China, especially stratified into obesity and non-obese diabetes. The aim of the present study was to investigate the prevalence and associated factors of non-obese diabetes in an underdeveloped area in South China, Guangxi. METHODS: Data derived from the Chinese Health and Nutrition Survey 2010-2012 involved a sample of 3874 adults from Guangxi. Questionnaires and oral glucose-tolerance tests were conducted, and fasting and 2 h glucose levels and serum lipids were measured. Logistic regression analysis was performed to assess associated factors for non-obese diabetes. RESULTS: 68.2% and 62.2% of instances of newly detected diabetes were those of non-obese diabetes based on BMI (NODB) and based on WC (NODW), respectively. The male sex, an age older than 50 years, lower education, hypertension, and hypertriglyceridemia were significantly associated with a higher risk of both NODB and NODW, while some associated factors for NODB were found different from those associated with NODW, and an interaction effect was found to increase the risk of NODW. CONCLUSIONS: Our study indicated that non-obese diabetes was highly prevalent in an underdeveloped area of South China. Non-obese diabetes should be considered for increased public attention in these areas. PMID- 27706057 TI - Firefighters' Physical Activity across Multiple Shifts of Planned Burn Work. AB - Little is currently known about the physical activity patterns of workers in physically demanding populations. The aims of this study were to (a) quantify firefighters' physical activity and sedentary time within (2-h periods) and across planned burn shifts; and (b) examine whether firefighters' activity levels during one shift or 2-h period was associated with their activity levels in the following shift or 2-h period. Thirty-four salaried firefighters (26 men, 8 women) wore an Actical accelerometer for 28 consecutive days. Time spent sedentary (SED) and in light- (LPA), moderate- (MPA) and vigorous-intensity physical activity (VPA) were derived using validated cut-points. Multilevel analyses (shift, participant) were conducted using generalised linear latent and mixed models. Firefighters spent the majority of a planned burn shift (average length 10.4 h) or 2-h period engaged in LPA (69% and 70%, respectively). No significant associations were observed between SED and physical activity levels between consecutive planned burned shifts or 2-h periods. The physical activity that a firefighter engaged in during one shift (or 2-h period) did not subsequently affect their physical activity levels in the subsequent shift (or 2 h period). Further research is needed to establish how workers in physically demanding populations are able to sustain their activity levels over long periods of time.

AB - An investigation on the effect of substituent at the 2-position of mono substituted quinoxalines in the synthesis of di-substituted quinoxaline derivatives via nucleophilic substitution reactions, is reported. Di-substituted quinoxalines bearing aryl-alky, aryl-aryl, aryl-heteroaryl, aryl-alkynyl, and amino-alkyl substituents were prepared in moderate to good yields. 2 Monosubstituted quinoxalines bearing a phenyl and butyl substituent reacted readily with alkyl-, aryl-, heteroaryl- and alkynyl- nucluephiles, giving di substituted quinoxalines. 2-Monosubstituted quinoxalines bearing an amine and alkynyl substituent only reacted with alkyl nucleophiles. Oxidative rearomatization to give 2,3-disubstituted quinoxaline products occurred in atmospheric O2. PMID- 27706059 TI - Real-Time Detection of a Self-Replicating RNA Enzyme. AB - A system was developed to detect the self-replication of an RNA enzyme in real time. The enzyme is an RNA ligase that undergoes exponential amplification at a constant temperature and can be made to operate in a ligand-dependent manner. The real-time system is based on a fluorimetric readout that directly couples the ligation event to an increase in florescence signal that can be monitored using standard instrumentation. The real-time system can also operate entirely with l RNA, which is not susceptible to degradation by ribonucleases that are present in biological samples. The system is analogous to real-time PCR, but with the potential to detect small molecules, proteins, and other targets that can be recognized by a suitable aptamer. The ligand-dependent self-replication of RNA has potential applications in molecular diagnostics and biosensing that benefit from the rapid, precise, and real-time detection of various target molecules.

AB - We have overcome the synthetic difficulty of 9,9',9'',9''',9'''',9''''' ((phenylsilanetriyl)tris(benzene-5,3,1-triyl))hexakis(9H-carbazole) (SimCP3) an advanced homologue of previously known SimCP2 as a solution-processed, high triplet gap energy host material for a blue phosphorescence dopant. A series of organic light-emitting diodes based on blue phosphorescence dopant iridium (III) bis(4,6-difluorophenylpyridinato)picolate, FIrpic, were fabricated and tested to demonstrate the validity of solution-processed SimCP3 in the device fabrication. PMID- 27706061 TI - Factors Influencing Health Knowledge and Behaviors among the Elderly in Rural China. AB - OBJECTIVES: Health knowledge and behaviors are the key elements that ensure high quality of health for the elderly. This study explored and determined the conditions and factors of health knowledge and behaviors that affect the elderly in rural China. METHODS: A cross-sectional research approach and random stratified sampling method were used in 12 towns and 48 villages in the Chongqing Municipality, Henan, and Zhejiang Provinces in China from June to September 2013. The collected data included: (1) socio-demographic characteristics of 1593 elderly people; (2) accuracy rate on health knowledge of the elderly, which was analyzed and compared among the three sample areas by using Chi-square test; and (3) mean scores on the health behaviors of the elderly, which were analyzed and compared by using analysis of variance (ANOVA). The multiple-linear regression method was used to analyze the factors affecting the health knowledge and behaviors of the elderly. RESULTS: Significant differences were observed among the nine items in the health knowledge questionnaire (p = 0.000 < 0.001). The average accuracy rate of the nine items was 57.43%. Significant differences were observed among the eleven items on the health behaviors of the elderly in the sample rural areas (p = 0.000 < 0.001). Age, economic level, degree of education, distance from home to medical institutions and disposable personal income (DPI) can affect the scores of the health knowledge and behaviors of the elderly (p = 0.000 < 0.001). CONCLUSIONS: Lack of health knowledge and poor health behaviors are common among the elderly in the sample areas of rural China. This deficiency poses a serious threat on the promotion of health conditions and the improvement of the level of health quality among the elderly. Different types of access to sources of health knowledge should be used to increase health knowledge scores of the elderly. Various potential intervening measures should also be adopted to improve their health behaviors of elderly people.

Investigations have identified that the problem in public rental housing estates was caused by the problematic solders used in the plumbing, and recommendations on enhancing the quality control system and strengthening the relevant water quality standards have been proposed. The cause for the same problem happening in other premises where soldering has not been adopted for water pipe connections is left unidentified. Considering the unidentified cause and the recommendations made, this study aims to identify the gaps in practice followed in Hong Kong for safeguarding the water quality of new installations. A holistic review of governing ordinances and regulations, products and materials used and the testing and commissioning requirements adopted in Hong Kong and elsewhere in the world were conducted. Based on international practices and parametric analysis, it was found that there are gaps in practices followed in Hong Kong, which are directly and indirectly leading to the lead-in-water crisis. Recommendations for improvement in the quality control system, and the water quality standards including the allowable lead content and leaching limit for products and materials and the testing and commissioning requirements on plumbing installations have been made. The review and the identified gaps would become useful reference for countries in strengthening their relevant water quality standards. PMID- 27706063 TI - A Potential Mechanism for the Anti-Apoptotic Property of Koumine Involving Mitochondrial Pathway in LPS-Mediated RAW 264.7 Macrophages. AB - Koumine is a kind of alkaloid extracted from Gelsemium elegans (G. elegans). Benth, which has shown promise as an anti-tumor, anxiolytic, and analgesic agent. In our present study, the effect of koumine on lipopolysaccharide (LPS)-mediated RAW 264.7 cell apoptosis was evaluated. MTT assays showed that koumine obviously increased cell viability in LPS-mediated RAW 264.7 macrophages. Preincubation with koumine ameliorated LPS-medicated apoptosis by decreasing reactive oxygen species (ROS) production, which resulted in a significant decrease in the levels of nitric oxide (NO) and inducible nitric oxide synthase (iNOS). In addition, koumine-pretreated RAW 264.7 macrophages exhibited reduction of LPS-induced levels of TNF-alpha, IL-1beta, and IL-6 mRNA. Furthermore, pretreatment with koumine suppressed LPS-mediated p53 activation, loss of mitochondrial membrane potential, caspase-3 activation, decrease of Bcl-2 expression, and elevation of Bax and caspase-3 expressions, suggesting that koumine might act directly on RAW 264.7 cells to inhibit LPS-induced apoptosis. It seems as though the mechanism that koumine possesses is the anti-apoptotic effect mediated by suppressing production of ROS, activation of p53, and mitochondrial apoptotic pathways in RAW 264 cells. Koumine could potentially serve as a protective effect against LPS induced apoptosis. PMID- 27706064 TI - Assessment of Atmospheric Algorithms to Retrieve Vegetation in Natural Protected Areas Using Multispectral High Resolution Imagery. AB - The precise mapping of vegetation covers in semi-arid areas is a complex task as this type of environment consists of sparse vegetation mainly composed of small shrubs. The launch of high resolution satellites, with additional spectral bands and the ability to alter the viewing angle, offers a useful technology to focus on this objective. In this context, atmospheric correction is a fundamental step in the pre-processing of such remote sensing imagery and, consequently, different algorithms have been developed for this purpose over the years. They are commonly categorized as imaged-based methods as well as in more advanced physical models based on the radiative transfer theory. Despite the relevance of this topic, a few comparative studies covering several methods have been carried out using high resolution data or which are specifically applied to vegetation covers. In this work, the performance of five representative atmospheric correction algorithms (DOS, QUAC, FLAASH, ATCOR and 6S) has been assessed, using high resolution Worldview-2 imagery and field spectroradiometer data collected simultaneously, with the goal of identifying the most appropriate techniques. The study also included a detailed analysis of the parameterization influence on the final results of the correction, the aerosol model and its optical thickness being important parameters to be properly adjusted. The effects of corrections were studied in vegetation and soil sites belonging to different protected semi-arid ecosystems (high mountain and coastal areas). In summary, the superior performance of model-based algorithms, 6S in particular, has been demonstrated, achieving reflectance estimations very close to the in-situ measurements (RMSE of between 2% and 3%). Finally, an example of the importance of the atmospheric correction in the vegetation estimation in these natural areas is presented, allowing the robust mapping of species and the analysis of multitemporal variations related to the human activity and climate change. PMID- 27706065 TI - Construction and Characterization of a Cellulolytic Consortium Enriched from the Hindgut of Holotrichia parallela Larvae. AB - Degradation of rice straw by cooperative microbial activities is at present the most attractive alternative to fuels and provides a basis for biomass conversion. The use of microbial consortia in the biodegradation of lignocelluloses could reduce problems such as incomplete synergistic enzymes, end-product inhibition, and so on. In this study, a cellulolytic microbial consortium was enriched from the hindgut of Holotrichia parallela larvae via continuous subcultivation (20 subcultures in total) under static conditions. The degradation ratio for rice straw was about 83.1% after three days of cultivation, indicating its strong cellulolytic activity. The diversity analysis results showed that the bacterial diversity and richness decreased during the consortium enrichment process, and the consortium enrichment process could lead to a significant enrichment of phyla Proteobacteria and Spirochaetes, classes Clostridia, Epsilonproteobacteria, and Betaproteobacteria, and genera Arcobacter, Treponema, Comamonas, and Clostridium. Some of these are well known as typical cellulolytic and hemicellulolytic microorganisms. Our results revealed that the microbial consortium identified herein is a potential candidate for use in the degradation of waste lignocellulosic biomass and further highlights the hindgut of the larvae as a reservoir of extensive and specific cellulolytic and hemicellulolytic microbes. PMID- 27706067 TI - Amplitude Dispersion Compensation for Damage Detection Using Ultrasonic Guided Waves. AB - Besides the phase and group velocities, the amplitude of guided wave mode is also frequency dependent. This amplitude dispersion also influences the performance of guided wave methods in nondestructive evaluation (NDE) and structural health monitoring (SHM). In this paper, the effects of amplitude dispersion to the spectrum and waveform of a propagating wave-packet are investigated. It is shown that the amplitude dispersion results in distortion in the spectrum of guided wave response, and thus influences the waveform of the wave-packet. To remove these effects, an amplitude dispersion compensation method is established on the basis of Vold-Kalman filter and Taylor series expansion. The performance of that method is then investigated by experimental examples. The results show that with the application of the amplitude dispersion compensation, the time reversibility could be preserved, which ensures the applicability of the time reversal method for damage detection. Besides, through amplitude dispersion compensation, the testing resolution of guided waves could be improved, so that the structural features located in the close proximity may be separately identified. PMID- 27706068 TI - Community Theories of Change: Linking Environmental Justice to Sustainability through Stakeholder Perceptions in Milwaukee, (WI, USA). AB - Environmental justice and sustainability are compatible lenses, yet action toward equity is often missing from urban sustainability initiatives. This study aims to assess the cohesion of these frameworks in practice. To do this, we parse individuals' theories of change, or how they identify and propose to resolve environmental injustices in the pursuit of sustainability. We posit that these theories of change are comprised of three main components: (1) perceived environmental benefits and burdens; (2) the causal pathways of environmental and social injustice; and (3) visions for positive change. Drawing from 35 stakeholder interviews in Milwaukee (WI, USA) we examine individual and institutional perspectives on environmental and social change and their links to the production of injustice. Our findings reveal that participants do not distinguish between environmental and social injustices. Instead, both social and environmental factors are implicated in injustice. Furthermore, we identify two mental maps for how social and economic change reproduce injustice. These findings suggest the need to reorient how urban injustice is considered and make efforts to acknowledge how a diversity of operational theories of change could either be divisive or could bring environmental justice and sustainability initiatives together. PMID- 27706069 TI - Spatial Distribution Balance Analysis of Hospitals in Wuhan. AB - The spatial distribution pattern of hospitals in Wuhan indicates a core in the central urban areas and a sparse distribution in the suburbs, particularly at the center of suburbs. This study aims to improve the gravity and Huff models to analyze healthcare accessibility and resources. Results indicate that healthcare accessibility in central urban areas is better than in the suburbs, where it increasingly worsens for the suburbs. A shortage of healthcare resources is observed in large-scale and high-class hospitals in central urban areas, whereas the resources of some hospitals in the suburbs are redundant. This study proposes the multi-criteria evaluation (MCE) analysis model for the location assessment in constructing new hospitals, which can effectively ameliorate healthcare accessibility in suburban areas. This study presents implications for the planning of urban healthcare facilities. PMID- 27706066 TI - Effects of Short-Term Exposure to Particulate Air Pollutants on the Inflammatory Response and Respiratory Symptoms: A Panel Study in Schoolchildren from Rural Areas of Japan. AB - The relationship between particulate air pollutants and respiratory symptoms in children has not been consistent among studies, potentially owing to differences in the inflammatory response to different particulate air pollutants. This study aimed to investigate the effect of particulate air pollutants on respiratory symptoms and the inflammatory response in schoolchildren. Three hundred-and-sixty children were included in the study. The children recorded daily respiratory symptom scores for October 2015. In addition, the daily amount of interleukin (IL)-6, IL-8, and tumor necrosis factor (TNF)-alpha production was assessed in THP1 cells stimulated with suspended particulate matter (SPM), which was collected every day during the study period. Generalized estimating equation logistic regression analyses were used to estimate the associations among respiratory symptoms and the daily levels of SPM, IL-6, IL-8, and TNF-alpha. Daily SPM levels were not associated with respiratory symptoms or the daily IL-6, IL-8, and TNF-alpha levels. Conversely, there was a significant association between respiratory symptoms and the daily IL-6, IL-8, and TNF-alpha levels. These results suggested that the effects of particulate air pollutants on respiratory symptoms in schoolchildren might depend more on the pro-inflammatory response to them than on their mass concentration. PMID- 27706070 TI - RT-qPCR Analysis of 15 Genes Encoding Putative Surface Proteins Involved in Adherence of Listeria monocytogenes. AB - L. monocytogenes adherence to food-associated abiotic surfaces and the development of biofilms as one of the underlying reasons for the contamination of ready-to-eat products is well known. The over-expression of internalins that improves adherence has been noted in cells growing as attached cells or at elevated incubation temperatures. However, the role of other internalin independent surface proteins as adhesins has been uncharacterized to date. Using two strains each of weakly- and strongly-adherent L. monocytogenes as platforms for temperature-dependent adherence assays and targeted mRNA analyses, these observations (i.e., sessile- and/or temperature-dependent gene expression) were further investigated. Microplate fluorescence assays of both surface-adherent strains exhibited significant (P < 0.05) adherence at higher incubation temperature (42 degrees C). Of the 15 genes selected for RT-qPCR, at least ten gene transcripts recovered from cells (weakly-adherent strain CW35, strongly adherent strain 99-38) subject to various growth conditions were over expressed [planktonic/30 degrees C (10), sessile/30 degrees C (12), planktonic/42 degrees C (10)] compared to their internal control (16SrRNA transcripts). Of four genes overexpressed in all three conditions tested, three and one were implicated as virulence factors and unknown function, respectively. PCR analysis of six unexpressed genes revealed that CW35 possessed an altered genome. The results suggest the presence of other internalin-independent adhesins (induced by growth temperature and/or substratum) and that a group of suspect protein members are worthy of further analysis for their potential role as surface adhesins. Analysis of the molecular basis of adherence properties of isolates of L. monocytogenes from food-associated facilities may help identify sanitation regimens to prevent cell attachment and biofilm formation on abiotic surfaces that could play a role in reducing foodborne illness resulting from Listeria biofilms. PMID- 27706071 TI - QUEST: Eliminating Online Supervised Learning for Efficient Classification Algorithms. AB - In this work, we introduce QUEST (QUantile Estimation after Supervised Training), an adaptive classification algorithm for Wireless Sensor Networks (WSNs) that eliminates the necessity for online supervised learning. Online processing is important for many sensor network applications. Transmitting raw sensor data puts high demands on the battery, reducing network life time. By merely transmitting partial results or classifications based on the sampled data, the amount of traffic on the network can be significantly reduced. Such classifications can be made by learning based algorithms using sampled data. An important issue, however, is the training phase of these learning based algorithms. Training a deployed sensor network requires a lot of communication and an impractical amount of human involvement. QUEST is a hybrid algorithm that combines supervised learning in a controlled environment with unsupervised learning on the location of deployment. Using the SITEX02 dataset, we demonstrate that the presented solution works with a performance penalty of less than 10% in 90% of the tests. Under some circumstances, it even outperforms a network of classifiers completely trained with supervised learning. As a result, the need for on-site supervised learning and communication for training is completely eliminated by our solution. PMID- 27706072 TI - Local Geographic Variation of Public Services Inequality: Does the Neighborhood Scale Matter? AB - This study aims to explore the effect of the neighborhood scale when estimating public services inequality based on the aggregation of social, environmental, and health-related indicators. Inequality analyses were carried out at three neighborhood scales: the original census blocks and two aggregated neighborhood units generated by the spatial "k"luster analysis by the tree edge removal (SKATER) algorithm and the self-organizing map (SOM) algorithm. Then, we combined a set of health-related public services indicators with the geographically weighted principal components analyses (GWPCA) and the principal components analyses (PCA) to measure the public services inequality across all multi-scale neighborhood units. Finally, a statistical test was applied to evaluate the scale effects in inequality measurements by combining all available field survey data. We chose Quito as the case study area. All of the aggregated neighborhood units performed better than the original census blocks in terms of the social indicators extracted from a field survey. The SKATER and SOM algorithms can help to define the neighborhoods in inequality analyses. Moreover, GWPCA performs better than PCA in multivariate spatial inequality estimation. Understanding the scale effects is essential to sustain a social neighborhood organization, which, in turn, positively affects social determinants of public health and public quality of life. PMID- 27706073 TI - Prevalence of Metabolic Syndrome among Korean Adolescents According to the National Cholesterol Education Program, Adult Treatment Panel III and International Diabetes Federation. AB - In both adults and children, metabolic syndrome (MetS) has been attributed to risk factors for type 2 diabetes and cardiovascular disease such as insulin resistance, abdominal obesity, hypertension, and dyslipidemia. This descriptive study aimed to compare the prevalence of MetS and diagnostic components according to the National Cholesterol Education Program, Adult Treatment Panel III (NCEP ATP III) and International Diabetes Federation (IDF) in 2330 Korean adolescents (10-18 years), using data from the 2010-2012 Korea National Health and Nutrition Examination Survey-V. The NCEP-ATP III and IDF were used to diagnose MetS and yielded prevalence rates of 5.7% and 2.1%, respectively, with no sex-related differences. The most frequent MetS diagnostic components according to the NCEP ATP III and IDF criteria were high triglyceride levels (21.2%) and low high density lipoprotein cholesterol levels (13.6%), respectively; approximately 50.1% and 33.1% of adolescents had at least one MetS diagnostic component according to the respective criteria. Both overweight/obese male and female adolescents exhibited significantly increased prevalence rates of MetS and related diagnostic components, compared to normal-weight adolescents. In conclusion, the prevalence rates of MetS and diagnostic components differ according to the NCEP-ATP III and IDF criteria. Henceforth, efforts are needed to establish diagnostic criteria for Korean adolescents. PMID- 27706075 TI - Urinary Sodium and Potassium Excretion and Carotid Atherosclerosis in Chinese Men and Women. AB - Limited studies have examined the association between sodium (Na) and potassium (K) levels and the risk of atherosclerosis. This study examined whether higher Na and Na/K levels and low K levels were independent risk factors for atherosclerosis. This community-based cross-sectional study included 3290 subjects (1067 men and 2223 women) 40 to 75 years of age in Guangzhou, China, between 2011 and 2013. Urinary excretion of Na and K were measured from the first morning void, and creatinine-adjusted values were used. The intima-media thickness (IMT) of the carotid common artery and the carotid bifurcation was measured with high-resolution B-mode ultrasonography. Dietary K and Na intake and other covariates were obtained by face-to-face interviews. A significant positive association was seen between urinary Na excretion and carotid atherosclerosis after adjustment for age, sex, and other lifestyle covariates. The odds ratios (OR) and 95% confidence interval (CI) of the highest (vs. lowest) quartile of urinary Na were 1.32 (1.04-1.66) for carotid plaques, 1.48 (1.18-1.87) for increased common carotid artery IMT, and 1.55 (1.23-1.96) for increased carotid bifurcation IMT (all p-trend < 0.01). A similar positive association was observed between urinary Na/K levels and carotid plaque and increased IMT, and between dietary Na intake and increased bifurcation IMT. Regarding potassium data, we only found a significantly lower presence of carotid plaque (OR 0.72, 95% CI 0.57 0.91) for quartile 2 (vs. 1) of urinary K. Our findings suggest that higher levels of urinary excretion Na and Na/K are significantly associated with greater presence of carotid atherosclerosis in Chinese adults. PMID- 27706074 TI - Antiproliferative and Antiangiogenic Effects of Punica granatum Juice (PGJ) in Multiple Myeloma (MM). AB - Multiple myeloma (MM) is a clonal B-cell malignancy characterized by an accumulation of clonal plasma cells (PC) in the bone marrow (BM) leading to bone destruction and BM failure. Despite recent advances in pharmacological therapy, MM remains a largely incurable pathology. Therefore, novel effective and less toxic agents are urgently necessary. In the last few years, pomegranate has been studied for its potential therapeutic properties including treatment and prevention of cancer. Pomegranate juice (PGJ) contains a number of potential active compounds including organic acids, vitamins, sugars, and phenolic components that are all responsible of the pro-apoptotic effects observed in tumor cell line. The aim of present investigation is to assess the antiproliferative and antiangiogenic potential of the PGJ in human multiple myeloma cell lines. Our data demonstrate the anti-proliferative potential of PGJ in MM cells; its ability to induce G0/G1 cell cycle block and its anti-angiogenic effects. Interestingly, sequential combination of bortezomib/PGJ improved the cytotoxic effect of the proteosome inhibitor. We investigated the effect of PGJ on angiogenesis and cell migration/invasion. Interestingly, we observed an inhibitory effect on the tube formation, microvessel outgrowth aorting ring and decreased cell migration and invasion as showed by wound-healing and transwell assays, respectively. Analysis of angiogenic genes expression in endothelial cells confirmed the anti-angiogenic properties of pomegranate. Therefore, PGJ administration could represent a good tool in order to identify novel therapeutic strategies for MM treatment, exploiting its anti-proliferative and anti angiogenic effects. Finally, the present research supports the evidence that PGJ could play a key role of a future therapeutic approach for treatment of MM in order to optimize the pharmacological effect of bortezomib, especially as adjuvant after treatment.

AB - With the aim of developing multiple input and multiple output (MIMO) coupling systems with a redundant parallel adjustment mechanism on the deployable antenna panel, a structural control integrated design methodology is proposed in this paper. Firstly, the modal information from the finite element model of the structure of the antenna panel is extracted, and then the mathematical model is established with the Hamilton principle; Secondly, the discrete Linear Quadratic Regulator (LQR) controller is added to the model in order to control the actuators and adjust the shape of the panel. Finally, the engineering practicality of the modeling and control method based on finite element analysis simulation is verified. PMID- 27706077 TI - Assessing Walking Strategies Using Insole Pressure Sensors for Stroke Survivors. AB - Insole pressure sensors capture the different forces exercised over the different parts of the sole when performing tasks standing up such as walking. Using data analysis and machine learning techniques, common patterns and strategies from different users to achieve different tasks can be automatically extracted. In this paper, we present the results obtained for the automatic detection of different strategies used by stroke survivors when walking as integrated into an Information Communication Technology (ICT) enhanced Personalised Self-Management Rehabilitation System (PSMrS) for stroke rehabilitation. Fourteen stroke survivors and 10 healthy controls have participated in the experiment by walking six times a distance from chair to chair of approximately 10 m long. The Rivermead Mobility Index was used to assess the functional ability of each individual in the stroke survivor group. Several walking strategies are studied based on data gathered from insole pressure sensors and patterns found in stroke survivor patients are compared with average patterns found in healthy control users. A mechanism to automatically estimate a mobility index based on the similarity of the pressure patterns to a stereotyped stride is also used. Both data gathered from stroke survivors and healthy controls are used to evaluate the proposed mechanisms. The output of trained algorithms is applied to the PSMrS system to provide feedback on gait quality enabling stroke survivors to self manage their rehabilitation. PMID- 27706079 TI - A Power-Optimized Cooperative MAC Protocol for Lifetime Extension in Wireless Sensor Networks. AB - In wireless sensor networks, in order to satisfy the requirement of long working time of energy-limited nodes, we need to design an energy-efficient and lifetime extended medium access control (MAC) protocol. In this paper, a node cooperation mechanism that one or multiple nodes with higher channel gain and sufficient residual energy help a sender relay its data packets to its recipient is employed to achieve this objective. We first propose a transmission power optimization algorithm to prolong network lifetime by optimizing the transmission powers of the sender and its cooperative nodes to maximize their minimum residual energy after their data packet transmissions. Based on it, we propose a corresponding power-optimized cooperative MAC protocol. A cooperative node contention mechanism is designed to ensure that the sender can effectively select a group of cooperative nodes with the lowest energy consumption and the best channel quality for cooperative transmissions, thus further improving the energy efficiency. Simulation results show that compared to typical MAC protocol with direct transmissions and energy-efficient cooperative MAC protocol, the proposed cooperative MAC protocol can efficiently improve the energy efficiency and extend the network lifetime. PMID- 27706078 TI - Strategies for Extending Metabolomics Studies with Stable Isotope Labelling and Fluxomics. AB - This is a perspective from the peer session on stable isotope labelling and fluxomics at the Australian & New Zealand Metabolomics Conference (ANZMET) held from 30 March to 1 April 2016 at La Trobe University, Melbourne, Australia. This report summarizes the key points raised in the peer session which focused on the advantages of using stable isotopes in modern metabolomics and the challenges in conducting flux analyses. The session highlighted the utility of stable isotope labelling in generating reference standards for metabolite identification, absolute quantification, and in the measurement of the dynamic activity of metabolic pathways. The advantages and disadvantages of different approaches of fluxomics analyses including flux balance analysis, metabolic flux analysis and kinetic flux profiling were also discussed along with the use of stable isotope labelling in in vivo dynamic metabolomics. A number of crucial technical considerations for designing experiments and analyzing data with stable isotope labelling were discussed which included replication, instrumentation, methods of labelling, tracer dilution and data analysis. This report reflects the current viewpoint on the use of stable isotope labelling in metabolomics experiments, identifying it as a great tool with the potential to improve biological interpretation of metabolomics data in a number of ways. PMID- 27706080 TI - Identification, Molecular Cloning of IL-1beta and Its Expression Profile during Nocardia seriolae Infection in Largemouth Bass, Micropterus salmoides. AB - In the present study, IL-1beta cDNA was identified and analyzed from largemouth bass (Micropterus salmoides). Full length IL-1beta mRNA was obtained using Rapid Amplification of cDNA Ends (RACE), which contains 78 bp 3'-UTR, a 455 bp 5'-UTR, and an open reading frame (ORF) of 702 bp coding for 233 amino acid residues. The molecular weight and theoretical isoelectric point of largemouth bass IL-1beta protein was predicted to be 26.7 kDa and 6.08 respectively. A largemouth bass IL 1beta phylogenetic analysis showed a close relation to the IL-1betas of striped trumpeter (Latris lineata), Chinese perch (Siniperca chuatsi), and Japanese sea bass (Lateolabrax japonicus). Peptidoglycan upregulated IL-1beta in the spleen and head kidney, while lipopolysaccharide upregulated detectable levels of IL 1beta in the spleen only. Largemouth bass, challenged with Nocardia seriolae (1.0 * 106 cfu/mL), showed a significant increase in IL-1beta at 3 and 5 days post infection (dpi) in the spleen, while in the head kidney significant expression was found at 2 and 3 dpi, peaking at 3 dpi. Furthermore, tumor necrosis factor alpha (TNF-alpha) showed significantly higher expression in the spleen at 3 and 5 dpi, and in the head kidney at 1 and 3 dpi, with expression decreasing at 5 dpi in both tissues. PMID- 27706081 TI - Golgi-Related Proteins GOLPH2 (GP73/GOLM1) and GOLPH3 (GOPP1/MIDAS) in Cutaneous Melanoma: Patterns of Expression and Prognostic Significance. AB - GOLPH2 and GOLPH3 are Golgi-related proteins associated with aggressiveness and progression of a number of cancers. Their prognostic significance in melanoma has not yet been analyzed. We performed immunohistochemical analysis for GOLPH2 and GOLPH3 in 20 normal skin, 30 benign nevi and 100 primary melanoma tissue samples and evaluated their expression in three compartments: cancer cells, tumor associated macrophages (TAMs) and cancer-associated fibroblasts (CAFs). High levels of both proteins in melanoma cells were associated with characteristics of aggressive disease, and shorter disease-free survival (DFS) and cancer-specific overall survival (CSOS). On the contrary, increased numbers of GOLPH2-positive and GOLPH3-positive TAMs were observed in thinner, non-ulcerated tumors, with brisk lymphocytic reaction and absent lymphangioinvasion. Distant metastases were not observed among patients with high numbers of GOLPH2-positive TAMs. Increased expression of either protein in TAMs was related to prolonged CSOS and DFS. Similarly, GOLPH3-expressing CAFs were more frequent in thin melanomas with low mitotic rate, without ulceration and lymphangioinvasion. Moreover, increased GOLPH3-positive CAFs correlated with the absence of regional or distant metastases, and with longer CSOS and DFS. GOLPH2 expression was not observed in CAFs. Our results suggest that GOLPH2 and GOLPH3 play a role in melanoma progression and are potential targets for molecular-based therapies.

In this study, an ultrasound-assisted extraction (UAE) technique together with GRAS (generally recognized as safe) solvents (ethanol and water) was used to maximize the extraction of antioxidants from Thelephora ganbajun. Five extraction parameters (ethanol concentration, solvent to solid ratio, extraction time, temperature and ultrasound power) were investigated by single-factor experiments, and then a central composite rotatable design was employed to study interaction of three key extraction parameters. The optimum conditions were as follows: 57.38% ethanol, 70.15 mL/g solvent to solid ratio, 10.58 min extraction time, 40 degrees C extraction temperature and 500 W ultrasound power. Under the optimum conditions, the antioxidant activity obtained was 346.98 +/- 12.19 umol Trolox/g DW, in accordance with the predicted value of 344.67 umol Trolox/g DW. Comparison of UAE with conventional maceration and Soxhlet extraction, the UAE method showed stronger extract efficiency in a shorter extraction time. These results showed that UAE was an effective technique to extract antioxidants from Thelephora ganbajun. Furthermore, the extracts obtained under the optimized conditions exhibited antiproliferative activities toward human lung (A549), breast (MCF-7), liver (HepG2) and colon (HT-29) cancer cells, especially for liver and lung cancer cells. In addition, rutin, 2 hydrocinnamic acid and epicatechin were identified in the extract, which might contribute to antioxidant and antiproliferative activities.

AB - The objective of this study was to determine the efficiency of rye and barley starch hydrolysis in mashing processes using cereal malts as a source of amylolytic enzymes and starch, and to establish the volatile profile of the obtained agricultural distillates. In addition, the effects of the pretreatment method of unmalted cereal grains on the physicochemical composition of the prepared mashes, fermentation results, and the composition of the obtained distillates were investigated. The raw materials used were unmalted rye and barley grains, as well as the corresponding malts. All experiments were first performed on a semi-technical scale, and then verified under industrial conditions in a Polish distillery. The fermentable sugars present in sweet mashes mostly consisted of maltose, followed by glucose and maltotriose. Pressure thermal treatment of unmalted cereals, and especially rye grains, resulted in higher ethanol content in mashes in comparison with samples subjected to pressureless liberation of starch. All agricultural distillates originating from mashes containing rye and barley grains and the corresponding malts were characterized by low concentrations of undesirable compounds, such as acetaldehyde and methanol. The distillates obtained under industrial conditions contained lower concentrations of higher alcohols (apart from 1-propanol) than those obtained on a semi-technical scale. PMID- 27706084 TI - Anti-Inflammatory Activity of Natural Products. AB - This article presents highlights of the published literature regarding the anti inflammatory activities of natural products. Many review articles were published in this regard, however, most of them have presented this important issue from a regional, limited perspective. This paper summarizes the vast range of review and research articles that have reported on the anti-inflammatory effects of extracts and/or pure compounds derived from natural products. Moreover, this review pinpoints some interesting traditionally used medicinal plants that were not investigated yet. PMID- 27706085 TI - Design and Construction of a Bilateral Haptic System for the Remote Assessment of the Stiffness and Range of Motion of the Hand. AB - The use of haptic devices in the rehabilitation of impaired limbs has become rather popular, given the proven effectiveness in promoting recovery. In a standard framework, such devices are used in rehabilitation centers, where patients interact with virtual tasks, presented on a screen. To track their sessions, kinematic/dynamic parameters or performance scores are recorded. However, as Internet access is now available at almost every home and in order to reduce the hospitalization time of the patient, the idea of doing rehabilitation at home is gaining wide consent. Medical care programs can be synchronized with the home rehabilitation device; patient data can be sent to the central server that could redirect to the therapist laptop (tele-healthcare). The controversial issue is that the recorded data do not actually represent the clinical conditions of the patients according to the medical assessment scales, forcing them to frequently undergo clinical tests at the hospital. To respond to this demand, we propose the use of a bilateral master/slave haptic system that could allow the clinician, who interacts with the master, to assess remotely and in real time the clinical conditions of the patient that uses the home rehabilitation device as the slave. In this paper, we describe a proof of concept to highlight the main issues of such an application, limited to one degree of freedom, and to the measure of the stiffness and range of motion of the hand. PMID- 27706086 TI - Towards Real-Time Detection of Gait Events on Different Terrains Using Time Frequency Analysis and Peak Heuristics Algorithm. AB - Real-time detection of gait events can be applied as a reliable input to control drop foot correction devices and lower-limb prostheses. Among the different sensors used to acquire the signals associated with walking for gait event detection, the accelerometer is considered as a preferable sensor due to its convenience of use, small size, low cost, reliability, and low power consumption. Based on the acceleration signals, different algorithms have been proposed to detect toe off (TO) and heel strike (HS) gait events in previous studies. While these algorithms could achieve a relatively reasonable performance in gait event detection, they suffer from limitations such as poor real-time performance and are less reliable in the cases of up stair and down stair terrains. In this study, a new algorithm is proposed to detect the gait events on three walking terrains in real-time based on the analysis of acceleration jerk signals with a time-frequency method to obtain gait parameters, and then the determination of the peaks of jerk signals using peak heuristics. The performance of the newly proposed algorithm was evaluated with eight healthy subjects when they were walking on level ground, up stairs, and down stairs. Our experimental results showed that the mean F1 scores of the proposed algorithm were above 0.98 for HS event detection and 0.95 for TO event detection on the three terrains. This indicates that the current algorithm would be robust and accurate for gait event detection on different terrains. Findings from the current study suggest that the proposed method may be a preferable option in some applications such as drop foot correction devices and leg prostheses.

AB - In the congestive heart failure (CHF) setting, chronic hyponatremia is very common. The present review aims at addressing topics relevant to the pathophysiology of hyponatremia in the course of CHF as well as its optimal treatment, including the main advantages and the limitations resulting from the use of the available dietary and pharmacological measures approved for the treatment of this electrolytic trouble. A narrative review is carried out in order to represent the main modalities of therapy for chronic hyponatremia that frequently complicates CHF. The limits of usual therapies implemented for CHF related chronic hyponatremia are outlined, while an original analysis of the main advancements achieved with the use of vasopressin receptor antagonists (VRAs) is also executed. The European regulatory restrictions that currently limit the use of VRAs in the management of CHF are substantially caused by financial concerns, i.e., the high costs of VRA therapy. A thoughtful reworking of current restrictions would be warranted in order to enable VRAs to be usefully associated to loop diuretics for decongestive treatment of CHF patients with hyponatremia. PMID- 27706087 TI - Characterization of Airborne Particles Collected from Car Engine Air Filters Using SEM and EDX Techniques. AB - Particulate matter accumulated on car engine air-filters (CAFs) was examined in order to investigate the potential use of these devices as efficient samplers for collecting street level air that people are exposed to. The morphology, microstructure, and chemical composition of a variety of particles were studied using scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX). The particulate matter accumulated by the CAFs was studied in two categories; the first was of removed particles by friction, and the second consisted of particles retained on the filters. Larger particles with a diameter of 74-10 um were observed in the first category. In the second one, the detected particles had a diameter between 16 and 0.7 um. These particles exhibited different morphologies and composition, indicating mostly a soil origin. The elemental composition revealed the presence of three groups: mineral (clay and asphalt), metallic (mainly Fe), and biological particles (vegetal and animal debris). The palynological analysis showed the presence of pollen grains associated with urban plants. These results suggest that CAFs capture a mixture of atmospheric particles, which can be analyzed in order to monitor urban air. Thus, the continuous availability of large numbers of filters and the retroactivity associated to the car routes suggest that these CAFs are very useful for studying the high traffic zones within a city. PMID- 27706089 TI - Susceptibility to Heat-Related Fluid and Electrolyte Imbalance Emergency Department Visits in Atlanta, Georgia, USA. AB - Identification of populations susceptible to heat effects is critical for targeted prevention and more accurate risk assessment. Fluid and electrolyte imbalance (FEI) may provide an objective indicator of heat morbidity. Data on daily ambient temperature and FEI emergency department (ED) visits were collected in Atlanta, Georgia, USA during 1993-2012. Associations of warm-season same-day temperatures and FEI ED visits were estimated using Poisson generalized linear models. Analyses explored associations between FEI ED visits and various temperature metrics (maximum, minimum, average, and diurnal change in ambient temperature, apparent temperature, and heat index) modeled using linear, quadratic, and cubic terms to allow for non-linear associations. Effect modification by potential determinants of heat susceptibility (sex; race; comorbid congestive heart failure, kidney disease, and diabetes; and neighborhood poverty and education levels) was assessed via stratification. Higher warm-season ambient temperature was significantly associated with FEI ED visits, regardless of temperature metric used. Stratified analyses suggested heat-related risks for all populations, but particularly for males. This work highlights the utility of FEI as an indicator of heat morbidity, the health threat posed by warm-season temperatures, and the importance of considering susceptible populations in heat health research. PMID- 27706090 TI - Interactions of beta-Conglycinin (7S) with Different Phenolic Acids-Impact on Structural Characteristics and Proteolytic Degradation of Proteins. AB - p-Coumalic acid (PCA), caffeic acid (CA), gallic acid (GA) and chlorogenic acid (CGA) are the major phenolic acids that co-exist with soy protein components in foodstuffs. Surprisingly, there are only a handful of reports that describe their interaction with beta-Conglycinin (7S), a major soy protein. In this report, we investigated the interaction between phenolic acids and soy protein 7S and observed an interaction between each of these phenolic acids and soy protein 7S, which was carried out by binding. Further analysis revealed that the binding activity of the phenolic acids was structure dependent. Here, the binding affinity of CA and GA towards 7S was found to be stronger than that of PCA, because CA and GA have one more hydroxyl group. Interestingly, the binding of phenolic acids with soy protein 7S did not affect protein digestion by pepsin and trypsin. These findings aid our understanding of the relationship between different phenolic acids and proteins in complex food systems. PMID- 27706092 TI - Black-White Disparities in Criminal Justice Referrals to Drug Treatment: Addressing Treatment Need or Expanding the Diagnostic Net? AB - Slightly more than half of admissions to U.S. publicly-funded treatment for marijuana use are referred by the criminal justice system; this pattern has remained for at least 20 years. Nationally, Blacks comprise nearly a third of treatment admissions for marijuana use. This article explores the interplay between race and criminal justice referrals to treatment for marijuana use. Using data from the (U.S.) 2011 Treatment Episode Data Set, we examine the relationship between race and diagnosis of cannabis use disorder (dependence versus abuse) among referrals to community-based treatment in North Carolina. We compare Black/White differences in cannabis diagnoses across four referral sources: the criminal justice system, healthcare providers, self, and other sources. Race was significantly related to type of diagnosis across all four referral sources, however, the nature of the relationship was distinctly different among criminal justice referrals with Whites being more likely than Blacks to be diagnosed with cannabis dependence. Moreover, the marijuana use profiles of criminal justice referrals differed substantially from individuals referred by other sources. The findings suggest that diagnoses of cannabis abuse (rather than dependence) may have worked to widen the diagnostic net by "capturing" individuals under control of the criminal justice system who manifested few problems with marijuana use, other than their involvement in the criminal justice system. The potential for a net-widening effect appeared to be most pronounced for Blacks. PMID- 27706091 TI - Modulation of Compartmentalised Cyclic Nucleotide Signalling via Local Inhibition of Phosphodiesterase Activity. AB - Cyclic nucleotide phosphodiesterases (PDEs) are the only enzymes that degrade the cyclic nucleotides cAMP and cGMP, and play a key role in modulating the amplitude and duration of the signal delivered by these two key intracellular second messengers. Defects in cyclic nucleotide signalling are known to be involved in several pathologies. As a consequence, PDEs have long been recognized as potential drug targets, and they have been the focus of intense research for the development of therapeutic agents. A number of PDE inhibitors are currently available for the treatment of disease, including obstructive pulmonary disease, erectile dysfunction, and heart failure. However, the performance of these drugs is not always satisfactory, due to a lack of PDE-isoform specificity and their consequent adverse side effects. Recent advances in our understanding of compartmentalised cyclic nucleotide signalling and the role of PDEs in local regulation of cAMP and cGMP signals offers the opportunity for the development of novel strategies for therapeutic intervention that may overcome the current limitation of conventional PDE inhibitors. PMID- 27706093 TI - Natural and Synthetic Coumarins with Effects on Inflammation. AB - In this review, we will present the different aspects of coumarins and derivatives, from natural origins or synthetically prepared, and their action on inflammation. Coumarins and also furo- and pyranocoumarins are found in many different plants. These compounds are very often investigated for antioxidant properties. Other biological properties are also possible and anti-inflammation activity is one of these. As coumarins are also available quite easily via synthesis, natural ones can be prepared this way but derivatives with special substituents are also feasible. A review on the same topic appeared in 2004 and our contribution will take into account everything published since then. PMID- 27706094 TI - 3D Printed Dry EEG Electrodes. AB - Electroencephalography (EEG) is a procedure that records brain activity in a non invasive manner. The cost and size of EEG devices has decreased in recent years, facilitating a growing interest in wearable EEG that can be used out-of-the-lab for a wide range of applications, from epilepsy diagnosis, to stroke rehabilitation, to Brain-Computer Interfaces (BCI). A major obstacle for these emerging applications is the wet electrodes, which are used as part of the EEG setup. These electrodes are attached to the human scalp using a conductive gel, which can be uncomfortable to the subject, causes skin irritation, and some gels have poor long-term stability. A solution to this problem is to use dry electrodes, which do not require conductive gel, but tend to have a higher noise floor. This paper presents a novel methodology for the design and manufacture of such dry electrodes. We manufacture the electrodes using low cost desktop 3D printers and off-the-shelf components for the first time. This allows quick and inexpensive electrode manufacturing and opens the possibility of creating electrodes that are customized for each individual user. Our 3D printed electrodes are compared against standard wet electrodes, and the performance of the proposed electrodes is suitable for BCI applications, despite the presence of additional noise. PMID- 27706096 TI - Transformation of Tertiary Benzyl Alcohols into the Vicinal Halo-Substituted Derivatives Using N-Halosuccinimides. AB - The efficiency of direct conversion of tertiary alcohols bearing a beta-hydrogen atom to vicinal halohydrins-chlorohydrins and bromohydrins-under green reaction conditions was tested preliminarily on model tertiary benzyl alcohols. Tertiary alcohols were successfully directly halogenated to vicinal halohydrins with N halosuccinimide in aqueous media. The efficiency of the reaction in water was significantly improved in the presence of sodium dodecyl sulphate as the surfactant. PMID- 27706095 TI - Soluble Fiber with High Water-Binding Capacity, Swelling Capacity, and Fermentability Reduces Food Intake by Promoting Satiety Rather Than Satiation in Rats. AB - To understand whether soluble fiber (SF) with high water-binding capacity (WBC), swelling capacity (SC) and fermentability reduces food intake and whether it does so by promoting satiety or satiation or both, we investigated the effects of different SFs with these properties on the food intake in rats. Thirty-two male Sprague-Dawley rats were randomized to four equal groups and fed the control diet or diet containing 2% konjac flour (KF), pregelatinized waxy maize starch (PWMS) plus guar gum (PG), and PWMS starch plus xanthan gum (PX) for three weeks, with the measured values of SF, WBC, and SC in the four diets following the order of PG > KF > PX > control. Food intake, body weight, meal pattern, behavioral satiety sequence, and short-chain fatty acids (SCFAs) in cecal content were evaluated. KF and PG groups reduced the food intake, mainly due to the decreased feeding behavior and increased satiety, as indicated by decreased meal numbers and increased inter-meal intervals. Additionally, KF and PG groups increased concentrations of acetate acid, propionate acid, and SCFAs in the cecal contents. Our results indicate that SF with high WBC, SC, and fermentability reduces food intake-probably by promoting a feeling of satiety in rats to decrease their feeding behavior. PMID- 27706097 TI - Anti-Inflammatory Effects of Aspalathus linearis and Cyclopia spp. Extracts in a UVB/Keratinocyte (HaCaT) Model Utilising Interleukin-1alpha Accumulation as Biomarker. AB - Ultraviolet B (UVB) radiation is one of the major predisposing risk factors of skin cancer. The anticancer and photoprotective effects of unoxidized rooibos (Aspalathus linearis) and honeybush (Cyclopia) herbal teas, containing high levels of dihydrochalones and xanthones, respectively, have been demonstrated in skin cancer models in vivo. In the current study, the anti-inflammatory effects of methanol and aqueous extracts of these herbal teas were investigated in a UVB/HaCaT keratinocyte model with intracellular interleukin-1alpha (icIL-1alpha) accumulation as a biomarker. Extracts of green tea (Camellia sinensis) served as benchmark. Both extracts of green tea and rooibos, as well as the aqueous extract of C. intermedia, enhanced UVB-induced inhibition of cell viability, proliferation and induction of apoptosis, facilitating the removal of icIL 1alpha. The underlying mechanisms may involve mitochondrial dysfunction exhibiting pro-oxidant responses via polyphenol-iron interactions. The methanol extracts of honeybush, however, protected against UVB-induced reduction of cell growth parameters, presumably via antioxidant mechanisms that prevented the removal of highly inflamed icIL-1alpha-containing keratinocytes via apoptosis. The dual antioxidant and/or pro-oxidant role of the polyphenolic herbal tea constituents should be considered in developing preventive strategies against UVB induced skin carcinogenesis. The indirect removal of UVB damaged keratinocytes by herbal tea extracts via apoptosis may find application in the prevention of photo induced inflammation. PMID- 27706098 TI - Effect of Raw Material, Pressing and Glycosidase on the Volatile Compound Composition of Wine Made From Goji Berries. AB - This study investigated the effect of raw material, pressing, and glycosidase on the aromatic profile of goji berry wine. The free-run and the pressed juice of dried and fresh goji berries were used for wine production, whereas glycosidase was applied to wine after fermentation. Dried goji berry fermented wine exhibited much stronger fruity, floral, caramel, and herbaceous odors due to higher levels of esters, beta-ionone and methionol. However, fresh berry fermented wine possessed stronger chemical notes due to higher levels of 4-ethylphenol. Pressing treatment reduced the fruity and caramel odors in these fermented wines, and fresh berry free-run juice fermented wine exhibited the least floral aroma. Glycosidase addition did not alter the aromatic composition of wines. The principal component analysis indicated that goji raw material played a primary role in differentiating the aromatic profiles of the wines due to the difference on the content of 20 esters, nine benzenes, eight aldehydes/ketones, three acids, two alcohols and six other volatiles. The content differences on isopentyl alcohol, styrene, benzyl alcohol, 1-octanol, (E)-5-decen-1-ol, 1-hexanol, and beta-cyclocitral resulted in the segregation of the wines with and without the pressing treatment, especially for fresh berry fermented wine. PMID- 27706099 TI - Conditional Entropy and Location Error in Indoor Localization Using Probabilistic Wi-Fi Fingerprinting. AB - Localization systems are increasingly valuable, but their location estimates are only useful when the uncertainty of the estimate is known. This uncertainty is currently calculated as the location error given a ground truth, which is then used as a static measure in sometimes very different environments. In contrast, we propose the use of the conditional entropy of a posterior probability distribution as a complementary measure of uncertainty. This measure has the advantage of being dynamic, i.e., it can be calculated during localization based on individual sensor measurements, does not require a ground truth, and can be applied to discrete localization algorithms. Furthermore, for every consistent location estimation algorithm, both the location error and the conditional entropy measures must be related, i.e., a low entropy should always correspond with a small location error, while a high entropy can correspond with either a small or large location error. We validate this relationship experimentally by calculating both measures of uncertainty in three publicly available datasets using probabilistic Wi-Fi fingerprinting with eight different implementations of the sensor model. We show that the discrepancy between these measures, i.e., many location estimates having a high location error while simultaneously having a low conditional entropy, is largest for the least realistic implementations of the probabilistic sensor model. Based on the results presented in this paper, we conclude that conditional entropy, being dynamic, complementary to location error, and applicable to both continuous and discrete localization, provides an important extra means of characterizing a localization method. PMID- 27706101 TI - Methodological Comparison between a Novel Automatic Sampling System for Gas Chromatography versus Photoacoustic Spectroscopy for Measuring Greenhouse Gas Emissions under Field Conditions. AB - Trace gases such as nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) are climate-related gases, and their emissions from agricultural livestock barns are not negligible. Conventional measurement systems in the field (Fourier transform infrared spectroscopy (FTIR); photoacoustic system (PAS)) are not sufficiently sensitive to N2O. Laser-based measurement systems are highly accurate, but they are very expensive to purchase and maintain. One cost effective alternative is gas chromatography (GC) with electron capture detection (ECD), but this is not suitable for field applications due to radiation. Measuring samples collected automatically under field conditions in the laboratory at a subsequent time presents many challenges. This study presents a sampling designed to promote laboratory analysis of N2O concentrations sampled under field conditions. Analyses were carried out using PAS in the field (online system) and GC in the laboratory (offline system). Both measurement systems showed a good correlation for CH4 and CO2 concentrations. Measured N2O concentrations were near the detection limit for PAS. GC achieved more reliable results for N2O in very low concentration ranges. PMID- 27706100 TI - Plant Resistance Inducers against Pathogens in Solanaceae Species-From Molecular Mechanisms to Field Application. AB - This review provides a current summary of plant resistance inducers (PRIs) that have been successfully used in the Solanaceae plant family to protect against pathogens by activating the plant's own defence. Solanaceous species include many important crops such as potato and tomato. We also present findings regarding the molecular processes after application of PRIs, even if the number of such studies still remains limited in this plant family. In general, there is a lack of patterns regarding the efficiency of induced resistance (IR) both between and within solanaceous species. In many cases, a hypersensitivity-like reaction needs to form in order for the PRI to be efficient. "-Omics" studies have already given insight in the complexity of responses, and can explain some of the differences seen in efficacy of PRIs between and within species as well as towards different pathogens. Finally, examples of field applications of PRIs for solanaceous crops are presented and discussed. We predict that PRIs will play a role in future plant protection strategies in Solanaceae crops if they are combined with other means of disease control in different spatial and temporal combinations. PMID- 27706102 TI - The Redox Status of Cancer Cells Supports Mechanisms behind the Warburg Effect. AB - To better understand the energetic status of proliferating cells, we have measured the intracellular pH (pHi) and concentrations of key metabolites, such as adenosine triphosphate (ATP), nicotinamide adenine dinucleotide (NAD), and nicotinamide adenine dinucleotide phosphate (NADP) in normal and cancer cells, extracted from fresh human colon tissues. Cells were sorted by elutriation and segregated in different phases of the cell cycle (G0/G1/S/G2/M) in order to study their redox (NAD, NADP) and bioenergetic (ATP, pHi) status. Our results show that the average ATP concentration over the cell cycle is higher and the pHi is globally more acidic in normal proliferating cells. The NAD+/NADH and NADP+/NADPH redox ratios are, respectively, five times and ten times higher in cancer cells compared to the normal cell population. These energetic differences in normal and cancer cells may explain the well-described mechanisms behind the Warburg effect. Oscillations in ATP concentration, pHi, NAD+/NADH, and NADP+/NADPH ratios over one cell cycle are reported and the hypothesis addressed. We also investigated the mitochondrial membrane potential (MMP) of human and mice normal and cancer cell lines. A drastic decrease of the MMP is reported in cancer cell lines compared to their normal counterparts. Altogether, these results strongly support the high throughput aerobic glycolysis, or Warburg effect, observed in cancer cells. PMID- 27706103 TI - In Vitro Metabolic Studies of REV-ERB Agonists SR9009 and SR9011. AB - SR9009 and SR9011 are attractive as performance-enhancing substances due to their REV-ERB agonist effects and thus circadian rhythm modulation activity. Although no pharmaceutical preparations are available yet, illicit use of SR9009 and SR9011 for doping purposes can be anticipated, especially since SR9009 is marketed in illicit products. Therefore, the aim was to identify potential diagnostic metabolites via in vitro metabolic studies to ensure effective (doping) control. The presence of SR9009 could be demonstrated in a black market product purchased over the Internet. Via human liver microsomal metabolic assays, eight metabolites were detected for SR9009 and fourteen metabolites for SR9011 by liquid chromatography-high resolution mass spectrometry (LC-HRMS). Structure elucidation was performed for all metabolites by LC-HRMS product ion scans in both positive and negative ionization mode. Retrospective data analysis was applied to 1511 doping control samples previously analyzed by a full-scan LC-HRMS screening method to verify the presence of SR9009, SR9011 and their metabolites. So far, the presence of neither the parent compound nor the metabolites could be detected in routine urine samples. However, to further discourage use of these potentially harmful compounds, incorporation of SR9009 and SR9011 into screening methods is highly recommended. PMID- 27706104 TI - Quasi-3D Modeling and Efficient Simulation of Laminar Flows in Microfluidic Devices. AB - A quasi-3D model has been developed to simulate the flow in planar microfluidic systems with low Reynolds numbers. The model was developed by decomposing the flow profile along the height of a microfluidic system into a Fourier series. It was validated against the analytical solution for flow in a straight rectangular channel and the full 3D numerical COMSOL Navier-Stokes solver for flow in a T channel. Comparable accuracy to the full 3D numerical solution was achieved by using only three Fourier terms with a significant decrease in computation time. The quasi-3D model was used to model flows in a micro-flow cytometer chip on a desktop computer and good agreement between the simulation and the experimental results was found. PMID- 27706105 TI - Biological Control of Mosquito Vectors: Past, Present, and Future. AB - Mosquitoes represent the major arthropod vectors of human disease worldwide transmitting malaria, lymphatic filariasis, and arboviruses such as dengue virus and Zika virus. Unfortunately, no treatment (in the form of vaccines or drugs) is available for most of these diseases andvectorcontrolisstillthemainformofprevention. Thelimitationsoftraditionalinsecticide-based strategies, particularly the development of insecticide resistance, have resulted in significant efforts to develop alternative eco-friendly methods. Biocontrol strategies aim to be sustainable and target a range of different mosquito species to reduce the current reliance on insecticide-based mosquito control. In thisreview, weoutline non-insecticide basedstrategiesthat havebeenimplemented orare currently being tested. We also highlight the use of mosquito behavioural knowledge that can be exploited for control strategies. PMID- 27706106 TI - Genome-Wide Identification, Characterization and Expression Analysis of the Solute Carrier 6 Gene Family in Silkworm (Bombyx mori). AB - The solute carrier 6 (SLC6) gene family, initially known as the neurotransmitter transporters, plays vital roles in the regulation of neurotransmitter signaling, nutrient absorption and motor behavior. In this study, a total of 16 candidate genes were identified as SLC6 family gene homologs in the silkworm (Bombyx mori) genome. Spatio-temporal expression patterns of silkworm SLC6 gene transcripts indicated that these genes were highly and specifically expressed in midgut, brain and gonads; moreover, these genes were expressed primarily at the feeding stage or adult stage. Levels of expression for most midgut-specific and midgut enriched gene transcripts were down-regulated after starvation but up-regulated after re-feeding. In addition, we observed that expression levels of these genes except for BmSLC6-15 and BmGT1 were markedly up-regulated by a juvenile hormone analog. Moreover, brain-enriched genes showed differential expression patterns during wandering and mating processes, suggesting that these genes may be involved in modulating wandering and mating behaviors. Our results improve our understanding of the expression patterns and potential physiological functions of the SLC6 gene family, and provide valuable information for the comprehensive functional analysis of the SLC6 gene family. PMID- 27706108 TI - OprD Repression upon Metal Treatment Requires the RNA Chaperone Hfq in Pseudomonas aeruginosa. AB - The metal-specific CzcRS two-component system in Pseudomonas aeruginosa is involved in the repression of the OprD porin, causing in turn carbapenem antibiotic resistance in the presence of high zinc concentration. It has also been shown that CzcR is able to directly regulate the expression of multiple genes including virulence factors. CzcR is therefore an important regulator connecting (i) metal response, (ii) pathogenicity and (iii) antibiotic resistance in P. aeruginosa. Recent data have suggested that other regulators could negatively control oprD expression in the presence of zinc. Here we show that the RNA chaperone Hfq is a key factor acting independently of CzcR for the repression of oprD upon Zn treatment. Additionally, we found that an Hfq-dependent mechanism is necessary for the localization of CzcR to the oprD promoter, mediating oprD transcriptional repression. Furthermore, in the presence of Cu, CopR, the transcriptional regulator of the CopRS two-component system also requires Hfq for oprD repression. Altogether, these results suggest important roles for this RNA chaperone in the context of environment-sensing and antibiotic resistance in P. aeruginosa. PMID- 27706107 TI - The SaeRS Two-Component System of Staphylococcus aureus. AB - In the Gram-positive pathogenic bacterium Staphylococcus aureus, the SaeRS twocomponent system (TCS) plays a major role in controlling the production of over 20 virulence factors including hemolysins, leukocidins, superantigens, surface proteins, and proteases. The SaeRS TCS is composed of the sensor histidine kinase SaeS, response regulator SaeR, and two auxiliary proteins SaeP and SaeQ. Since its discovery in 1994, the sae locus has been studied extensively, and its contributions to staphylococcal virulence and pathogenesis have been well documented and understood; however, the molecular mechanism by which the SaeRS TCS receives and processes cognate signals is not. In this article, therefore, we review the literature focusing on the signaling mechanism and its interaction with other global regulators. PMID- 27706109 TI - 2-(2-Phenylethyl)chromone Derivatives of Agarwood Originating from Gyrinops salicifolia. AB - Three new2-(2-phenylethyl)chromone derivatives (1-3) and a new2-(2 phenylethenyl)chromone derivative (4), together with two known 2-(2 phenylethyl)chromone derivatives (5-6), were isolated from agarwood originating from Gyrinops salicifolia Ridl. The structures of compounds 1-4 were elucidated by comprehensive spectroscopic techniques (UV, IR, 1D and 2D-NMR) and MS analysis, as well as by comparison with the literature. Compounds 1, 2, and 5 showed moderate cytotoxicity against human tumor K562, BEL-7402, and SGC-7901 cell lines with IC50 values of 5.76 to 20.1 uM. PMID- 27706112 TI - Oxygenized low density lipoprotein down-regulates the TRPV4 protein expression of macrophage through activation of peroxisome proliferator-activated receptor gamma. AB - BACKGROUND: TRPV4, a non-selective cation channel, is involved in lipometabolism and atherosclerosis. However, whether TRPV4 participates in oxygenized low density lipoprotein (oxLDL)-induced foam cell formation remains unknown. The present study investigates the effect of oxLDL on the expression of TRPV4 in macrophages and its underlying mechanisms. METHODS: The expression of TRPV4 in RAW264.7 and phorbol-12-myristate-13-acetate (PMA) induced U937, THP-1 cells was detected by immunofluorescence, and western blot was used to detect the TRPV4 expression before and after PMA induction. Each cell line was divided into three groups, including control group, native low-density lipoprotein (nLDL) (100 MUg/mL) group and oxLDL (100MUg/mL) group; the expression of TRPV4 in each group was measured using immunohistochemistry and western blot. TRPV4 protein expression was detected by western blot after RAW 264.7 cells were treated with 0, 0.01 MUM, 0.1 MUM and 1 MUM T0070907 or preincubated with 0.1 MUM T0070709 for 1 h before incubation with oxLDL for 24 h. RESULTS: In all macrophage cell lines, TRPV4 was widely expressed. PMA increased TRPV4 expression in U937 and THP-1 cells. There was no significant difference in TRPV4 expression in the nLDL group compared to that in the control group; however a significant reduction in TRPV4 expression was detected in the oxLDL group compared to that in the control and nLDL groups using measurements obtained from both immunohistochemistry and western blot. The PPARgamma inhibitor T0070907 enhanced the basal expression of TRPV4 and protected RAW264.7 cells from oxLDL-induced TRPV4 down-regulation. CONCLUSIONS: This study revealed that TRPV4 was widely expressed in macrophages and that oxLDL could induce the down-regulation of TRPV4 expression through its actions on PPARgamma. This study may serve as an important first step for further investigation into the roles of TRPV4 in macrophage-derived foam cell formation in atherosclerosis.

AB - Multinucleate cell angiohistiocytoma (MCA) represent an uncommon benign fibrohistiocytic vascular lesion that sometimes may go undiagnosed because of its clinical and hystopathological similarities with benign fibrous histiocytoma and other soft-tissue neoplasms especially when localized on oral cavity or semi mucosa. We report the case of a solitary multinucleate cell angiohistiocytoma on the lower lip of a 46-year old woman suggesting that this rare lesion should be considered in the differential diagnosis of the oral soft-tissue neoplasms. PMID- 27706111 TI - Downregulation of Enhancer of Zeste Homolog 2 (EZH2) is essential for the Induction of Autophagy and Apoptosis in Colorectal Cancer Cells. AB - Increasing evidence indicates that elevated expression of enhancer of zeste homolog 2 gene (EZH2) in many human malignant tumors acts a significant role in the oncogenic process. However, the underlying molecular mechanism is still unclarified. It is evident that apoptosis and autophagy of tumor cells is crucial for the tumorigenesis and progression of cancer, however, the exact role of EZH2 plays in apoptosis and autophagy has not been fully elucidated in colorectal cancer (CRC). Our previous study found that the expression level of EZH2 was higher in CRC tumor tissues than in the paired normal tissues using immunohistochemical analysis. We also recently found that the autophagy-related gene-related protein Ambra1 plays an important role in the autophagy pathway in CRC cells. In this study, mRNA and protein expression of EZH2 in four CRC cell lines were tested at first and RKO and HCT116 cells showed the highest levels among them. Here we transfected with EZH2-shRNA, or added DZNep (an EZH2 inhibitor) to RKO and HCT116 cells in order to detect the effect of EZH2 on autophagy via determining the change of the protein expression of LC3 and Ambra1. The outcome indicated an obvious decrease of autophagy level in cells transfected with EZH2-shRNA or DZNep. We also found the apoptotic rate of cells was elevated significantly after downregulation of EZH2. In addition, compared to control group, CRC cells transfected with EZH2-shRNA or added DZNep revealed a significantly increased G1 cell cycle rate and an obvious decrease in the G2 cell cycle rate. Further analysis showed that knockdown of EZH2 induced cell-cycle arrest in CRC cells. Meanwhile, downregulation of EZH2 in CRC cells induces autophagy and apoptosis. Taken together, our results suggest that EZH2 plays a critical role in autophagy and apoptosis in the progression of CRC, which potentially facilitates the development of an ideal strategy for combating colorectal cancer. PMID- 27706114 TI - Antibodies against antigens related to scleroderma in a cohort of patients with morphea. AB - BACKGROUND: Morphea is a rare fibrosing skin disorder. Antinuclear antibodies (ANA), anti-histone and rheumatoid factor are detected in high rate of morphea cases. Scleroderma-related antibodies are usually absent. METHODS: Twenty-one adult patients affected by morphea were examined at the time of enrollment and after 6 months with the assessment of clinical outcome measures of disease severity and damage. Healthy subjects were considered as normal controls while patients affected by systemic sclerosis and other connective tissue diseases (CTD) were considered as pathological controls. Serum samples from all the patients and controls were analyzed for the detection of ANA, anti-nucleosome antibodies, anti-dsDNA and anti-extractable nuclear antigen. Scleroderma-related autoantibodies were searched using a line-blot test. RESULTS: We enrolled 21 patients affected by morphea. ANA were found in 12 patients (57%). Anti-DNA and anti-nucleosome antibodies were negative in all cases. Systemic sclerosis specific antibodies were found in 11 morphea patients (52.4%) and one healthy control (6.25%). In patients affected by systemic sclerosis (100%) and different CTD (%), scleroderma-related autoantibodies were more frequently detected than in morphea (52.4%). In morphea, anti-TRIM21/Ro52 antibodies were found in 4 patients (36.4%) and resulted to be the most frequently detected antibodies also in two groups of SSC and CTD. CONCLUSIONS: The high prevalence of ANA and the identification of some antagonists of systemic sclerosis-related autoantibodies, confirm the idea of a significant activation of autoimmune system in morphea.

AB - During the past ten years, several new hepatitis E viruses (HEVs) have been identified in various animal species. In parallel, the number of reports of autochthonous hepatitis E in Western countries has increased as well, raising the question of what role these possible animal reservoirs play in human infections. The aim of this review is to present the recent discoveries of animal HEVs and their classification within the Hepeviridae family, their zoonotic and species barrier crossing potential, and possible use as models to study hepatitis E pathogenesis. Lastly, this review describes the transmission pathways identified from animal sources. PMID- 27706115 TI - Childhood psoriasis: a survey among pediatricians in Italy. AB - BACKGROUND: Psoriasis is one of the most common inflammatory skin diseases. There seem to be an increasing interest in childhood psoriasis in recent years. METHODS: We conducted a survey among pediatricians in Italy. 50 pediatricians from different areas in Italy (north, center and south) were invited to participate, 37 were responding and active in data collection. Doctors were asked to review their databases and to fill a form providing a series of information about all patients diagnosed with psoriasis attending their ambulatory. RESULTS: The total number of patients referring to the responding doctors was 28086. Of these, 66 were diagnosed with psoriasis. Mean age was 5.7, (6.3 in males and 5.1 in females). The majority of patients presented plaque psoriasis (N.=44; 66.7%), followed by inverse (N.=9; 13.6%), and guttate psoriasis (N.=7; 10.6%). The main site of presentation was the trunk (51.5%), followed by scalp (15.2%) and napkin area (12.1%). Fifteen patients presented nail psoriasis (22.7%). In the majority of cases no family history was reported (83.3%), first degree relatives presented psoriatic lesions in only 7 cases (10.6%). The comorbidity most frequently reported was overweight (N.=16, 25.4%), followed by atopic dermatitis (N.=12; 18.2%). Differences in the main pattern of presentation were found between male and female patients, in particular, a plaque type psoriasis was more frequent in males (79.4% vs. 53.1%; P=0.048). Female patients presented psoriasis of the napkin area more frequently than males (21.9% vs. 2.9%, P=0.025). CONCLUSIONS: Peculiar pattern of presentation can be detected in childhood psoriasis. Further studies are needed to validate these findings. PMID- 27706116 TI - Efficacy of the prophylactic administration of tramadol against postoperative shivering: a meta-analysis of randomized controlled trials. AB - INTRODUCTION: Postoperative shivering (POS) is a common complication that occurs after regional and general anesthesia. Thus far, numerous studies have reported on the effectiveness of tramadol in preventing or treating POS. Here, we performed a meta-analysis to assess the efficacy of tramadol in the prevention of POS. EVIDENCE ACQUISTION: We systematically searched PubMed, Embase and the Cochrane Library to identify studies of the efficacy of tramadol in the prevention of POS. The results are expressed as relative ratios (RRs) and the corresponding 95% confidence intervals (CIs). EVIDENCE SYNTHESIS: Seventeen studies with a total of 1438 patients were included. Seven hundred seventy-seven of these patients received tramadol, and 661 received placebo. Compared with placebo, the patients who received tramadol exhibited a significant reduction in the incidence of POS based on subgroup analyses according to anesthesia (RR: 0.27; 95% CI: 0.19-0.37; P<0.00001), different doses of tramadol (RR: 0.26; 95% CI: 0.19-0.35; P<0.00001), the rescue drug used (RR: 0.19; 95% CI: 0.10-0.35; P<0.00001) and the number of patients who experienced severe POS (RR: 0.17; 95% CI: 0.12-0.23; P<0.00001). Moreover, the administration of tramadol did not increase the risks of postoperative nausea and vomiting (PONV), hemodynamic turbulence, respiratory depression or deep sedation. CONCLUSIONS: This meta analysis revealed that prophylactic tramadol effectively prevents POS and reduces rescue medication use without significant adverse effects. PMID- 27706117 TI - The effect of routine availability of sugammadex on postoperative respiratory complications: a historical cohort study. AB - BACKGROUND: Postoperative residual curarisationf is a preventable cause of postoperative morbidity. Although sugammadex has been shown to reduce the risk of residual curarisation, it has not yet been shown if this directly translates to a reduction in morbidity. We aimed to demonstrate whether the introduction of unrestricted sugammadex for routine reversal changed the incidence of post operative respiratory diagnoses and the rate of airway and respiratory complications in the post-operative care unit. METHODS: A historical cohort study of 1257 patients who underwent general surgical or ear, nose and throat (ENT) procedures before and after the introduction of unrestricted availability of sugammadex. Patient records were used to identify the incidence of postoperative in-hospital respiratory diagnoses and of airway complications in PACU, the pattern of muscle relaxant use and the relative costs associated with the routine availability of sugammadex. RESULTS: Unrestricted sugammadex availability was associated with a significant reduction in the rate of a postoperative in hospital respiratory diagnosis; Odds Ratio (OR) = 0.20 (95%CI 0.05-0.72, p=0.01). Furthermore, the use of sugammadex itself was also associated with a reduction in inhospital respiratory diagnoses; OR = 0.26 (95%CI 0.08-0.94, p=0.04). Unrestricted sugammadex was also associated with a decrease in the need for manual airway support in the recovery room (3.2% vs 1.1%, p=0.02) and a decrease in patients being transferred intubated to ICU (5.5% vs 1.3%, p<0.001). CONCLUSION: Unrestricted sugammadex availability is associated with a reduction in post-operative respiratory complications. A well-designed, prospective randomised trial is needed to provide further validation of the data. PMID- 27706118 TI - Cervical facet joint syndrome: a possible cause of chronic cervicobrachial pain. PMID- 27706119 TI - Serum motilin levels and motilin gene polymorphisms in children with functional constipation. AB - BACKGROUND: Functional constipation is an important clinical problem among chidden all over the world. Its main cause is not completely understood. Motilin is a gastrointestinal hormone that increases intestinal motility. In this study, we aimed to investigate the serum motilin levels and its relationship with stool consistency and motilin gene polymorphisms in constipated children. METHODS: In this study we investigated 91 constipated patients (mean age 6.84 +/- 3.55 years) and 100 healthy controls (mean age 7.78 +/- 4.25 years). Serum motilin levels were assessed by sandwich enzyme-linked immunosorbent assay. rs2281820 (c.44 C>T) and rs2281818 (c.66 C>T) mutations were evaluated for motilin gene polymorphisms. RESULTS: Serum motilin levels were significantly lower in constipated children than healthy controls (6.20 +/- 7.86 pg/mL vs. 11.54 +/- 17.89 pg/mL, respectively, p=0.008). Serum motilin levels were significantly correlated with Bristol stool scale rate (r = 0.193, p= 0.011) in whole study group, but in the constipation group there was no significant correlation (r= - 0.072, p= 0.528). There were no differences in terms of presence or distribution of the polymorphisms of rs2281820 (c.44 C>T) and rs2281818 (c.66 C>T) in both groups. There was not a significant difference between different polymorphism groups regarding serum motilin concentrations in whole study group and also in both of the study groups. CONCLUSION: This study indicated for the first time that serum motilin levels decreased in constipated children. Further studies are needed to clarify whether motilin or motilin gene polymorphisms has a role in pathogenesis of functional constipation. PMID- 27706121 TI - Reaction to the sensory integration therapy in children with postural stability deficits. AB - BACKGROUND: The goal was to examine the influence of sensory integration therapy (SIT) on one leg standing in children with deficits of the postural stability. METHODS: 28 children 4 - 6 year old that could not stand on one leg for more than 20 seconds were randomly divided into control "C" and experimental "E" groups. Group "C" participated in standard classes in the kindergarten. Group "E" participated in sensory integration therapy (SIT) for 2 weeks, 5 times a week (additionally to the standard classes). RESULTS: Results of the experiment show that the skill of standing on one leg has significantly improved (p<0.01) in the group that underwent additional therapy. The change in time of standing on the right leg with eyes open in the E group was statistically and significantly higher than the changes observed in the same time in group C (F = 22.5, p = 0.001' eta2 = 0.44). Similarly, significant changes in time of standing on the right leg with eyes closed were observed in group E. The foregoing changes were bigger in group E than in group C (F = 16. 1 , p = 0.004, eta2 = 0.36). The analysis post hoc revealed that while there were no significant differences between the two groups on the pretest (p>0.05), there were significant differences between groups in right leg standing test with eyes open or closed on posttest. (p<0.05). Similar results were observed during on the one, left leg standing. The time of one leg standing with both eyes open and closed improved more significantly in group E than in group C (F = 20.4, p = 0.001, eta2 = 0.42 respectively for the test with eyes open and F = 7.4, p = 0.010, eta2 = 0.21 for the test with eyes closed). The analysis post hoc revealed that while there were no significant differences between the two groups on the pretest (p>0.05), there were significant differences between groups in left leg standing test with eyes open or closed on posttest. (p<0.05). CONCLUSIONS: Research conducted show that there is a positive influence of SIT on children with low level of postural stability. Its significant improvement in children with low levels of postural stability is important not only for the current functioning of those children but for their future - by protecting them from falling down and from injuries. PMID- 27706120 TI - Effect of liposomes, vitamins A and E nasal spray in reducing the healing time after septoplasty with concurrent turbinate surgery in adolescents. AB - BACKGROUND: This study evaluates endoscopic and quality of life (QoL) outcomes in two groups, composed by both allergic (A) and non-allergic (N-A) adolescents undergoing septoplasty with concurrent turbinate surgery by radiofrequency treated after surgery with nasal spray containing liposomes and vitamins A and E. METHODS: This double-blind randomized study was carried out on 40 patients (22 males, 18 females, mean age 15.5+/-1.0 years) undergoing septoplasty and volumetric tissue reduction of inferior turbinates by radiofrequency for post traumatic deformities and severe nasal obstruction. We enrolled 20 subjects with positive skin prick tests and 20 with negative skin prick tests (SPT) to aeroallergens. All subjects underwent the Visual Analogue Scale (VAS) questionnaire and the nasal endoscopy score by Lund and Kennedy (LK) at baseline before surgery (T0) and 15 days (T15) and 21 days (T21) after treatment. After surgery, the nose was not packed and the day after surgery all subjects were randomized into two groups, experimental arm group I (GI) and control arm group II (GII) and given the treatment, nasal spray containing liposomes composed of phospholipids, fatty acids, and vitamin A and E for group I and saline solution (sodium chloride 0.9%) for group II. RESULTS: After therapy, the VAS and LK scores were better (P<0.05) in the investigational than in the control arm in both sub-groups (A and N-A). CONCLUSIONS: Our findings suggested that liposomal, vitamins A and E nasal spray improves the QoL in the early postoperative period, both in A and N-A sub-groups. PMID- 27706122 TI - A systematic review of the association between allergic asthma and autism. AB - INTRODUCTION: Autism Spectrum Disorder represents a burdensome condition in early childhood, with a number of risk factors proposed to explain its pathogenesis, most of which without a reliable scientific basis. Allergic asthma is likely to be one of the possible comorbilities of autism. EVIDENCE ACQUISITION: In this paper, the relationship between autism and allergic asthma was analyzed through a systematic literature review, conducted according to the PRISMA Guidelines. The review was performed on PubMed and Science Direct database and covered the period January 1, 2004-July 9, 2016. The search was limited to articles published in peer-reviewed journals. The obtained results were sorted by relevance and the most significant case-control, epidemiological and nationwide-based works associating autism and allergic asthma in humans were selected. EVIDENCE SYNTHESIS: A slight correlation between these conditions has been found in more than a half studies selected, suggesting a possible association between the two diseases. Small sample sizes of some works and some methodological limitations rise uncertainty about this link. CONCLUSIONS: Autism Spectrum Disorder and asthma could be associated conditions, as evidenced by the higher prevalence of asthma in autistic children with respect to typically developed controls, with also a verisimilar biological basis. Despite that, future studies are required to provide more reliable data, also by employing animal models, to better clarify this, still unsure, relationship. Methods for study selection and inclusion criteria were specified in advance and documented in PROSPERO protocol #CRD42014012851. PMID- 27706123 TI - Non-invasive ultrasound measurements in male patients with LUTS and benign prostatic obstruction: implication for diagnosis and treatment. AB - BACKGROUND: To evaluate the role of the ultrasound assessments of the bladder/detrusor wall thickness (BWT/DWT) and the ultrasound estimated bladder weight (UEBW) in lower urinary tract symptoms diagnosis and treatment. EVIDENCE ACQUISITION: A systematic literature search from January 1995 until February 2016 was performed on PubMed using the following terms: "bladder weight", "bladder wall thickness", "detrusor wall thickness", "LUTS", "bladder outlet obstruction" (BOO), "benign prostatic obstruction". Additional references were obtained from the reference list of full-text manuscripts. Abstracts presented at the annual congresses of the European Association of Urology, American Urology Association and the International Continence Society were also included. EVIDENCE SYNTHESIS: BWT and DWT are accurate predictors of BOO. Despite several differences in the technique assessment, population characteristics and study design, the BWT/DWT accuracy for BOO was close to 90%. Furthermore, the ultrasound evaluation of bladder/detrusor thickness correlates positively with symptoms score and the main clinical parameters in BPH patients. Lastly, BWT and DWT have proved to be optimal predictor of response to medical/surgical treatment of lower urinary tract symptoms/benign prostatic obstruction (LUTS/BPO). However, the lack of standardization among the available studies marks these methods promising but still experimental and further studies are needed to clarify the standard methodology. CONCLUSIONS: The ultrasound evaluation of bladder/detrusor thickness appears to be simple, highly accurate and non-invasive technique to predict BOO and to evaluate the clinical outcomes after medical/surgical treatments for LUTS/BPH. The implementation of these techniques and their standardization will probably better define their role in the diagnostic algorithms of patients with LUTS and possibly reduce the number of unnecessary pressure flow-studies. PMID- 27706124 TI - Comparison of GreenLight laser and transurethral resection of the prostate baseline characteristics and outcomes: lessons learned from the Clinical Research Office of the Endourological Society GreenLight Laser Study. AB - BACKGROUND: To compare baseline characteristics and outcomes of patients undergoing GreenLight laser vaporization (GL) or transurethral resection of the prostate (TURP) in a real life setting. METHODS: In this prospective observational cohort, the Clinical Research Office of the Endourological Society (CROES) collected data of consecutive GL or TURP treated patients. Treatment involved one of three GL laser powers (80 W, 120 W or 180 W) based on availability in each participating centre, or TURP. Data on baseline characteristics as well as functional measures were collected at three time points: 6-12 weeks, 6, and 12months after surgery. Functional measures included urinary flow parameters, perceived prostate function (IPSS), perceived erectile function (IIEF-5) and complications. RESULTS: Seven hundred thirteen patients underwent GL, and 234 patients underwent TURP. Overall, patients treated with GL show higher BMI, IIEF and medication use, together with lower urinary function (voided volume, incontinence, urinary retention) at baseline. After the procedure, despite higher antibiotic and antimuscarinic use and shorter hospital stay, readmission rates, PVR, PSA were higher, but Qmax, and IIEF were lower in the GL group. The rate of post-operative complications was 10.3% and 5.2% for the TURP and GL group, respectively (P=0.006). CONCLUSIONS: We were unable to categorically state which procedure is superior. This observational study confirms that treatment decision for either TURP or GL is not based on patient characteristics. PMID- 27706125 TI - The impact of nocturnal polyuria in older people with nocturnal LUTS. AB - BACKGROUND: Bladder dysfunctions often express the presence of lower urinary tract symptoms (LUTS) and are common in older people. The aim of this study was to analyze the micturition, incontinence and residual in older subjects, evaluating the role of nocturnal polyuria. METHODS: Eighty-six patients aged 65 or older with invalidating LUTS were hospitalized for 24 hours. The maximum bladder capacity, mean micturition volume, post voiding residual and incontinence volume were recorded and analyzed day-time and night-time. Three groups were defined, i.e. nocturia, nocturnal incontinence and nocturnal polyuria (NP), and patients with or without NP were analyzed. RESULTS: With a majority of female patients 85% and a mean age of 74.3+/-5.96 years, a high incidence of nocturia (76%) was observed. NP was associated with nocturia in 56 patients (86%). In the three groups, the maximum bladder capacity and mean micturition volume were statistically higher during the night. Patients with nocturia or nocturnal incontinence associated to NP presented with a higher nocturnal maximum bladder capacity and mean micturition volume. A higher nocturnal post-void residual (PVR) was observed in patients with Nocturnal Incontinence associated with NP (P=0.03). Patients without NP presented significantly higher diurnal results. CONCLUSIONS: Nocturnal LUTS in older people is the result of a high nocturnal urine production related to NP with a higher nocturnal bladder capacity. The analyses of micturition, incontinence and PVR, and the accurate evaluation of the presence or absence of NP seems to be the key point for a better therapeutic choice in patients suffering by Nocturnal LUTS. PMID- 27706127 TI - Regulatory T cells decrease invariant natural killer T cell-mediated pregnancy loss in mice. AB - Pregnancy loss is the commonest complication of pregnancy. The causes of pregnancy loss are poorly understood. It has been reported that stimulation of invariant natural killer T (iNKT) cells using alpha-galactosylceramide (alphaGC) induces pregnancy loss in mice. Here we investigated the mechanisms, especially the role of regulatory T (Treg) cells, in iNKT cell-mediated pregnancy loss. We found that injection of alphaGC rapidly induced fetal resorption, activated decidual iNKT cells, decreased the percentage of decidual Treg cells and their interleukin (IL)-10 and transforming growth factor (TGF)-beta production, and upregulated the levels of interferon (IFN)-gamma, tumor necrosis factor-alpha, IL 4, and IL-10 in serum. Adoptive transfer of iNKT cells from wild-type (WT) and IL 4-/- mice but not IFN-gamma-/- mice into alphaGC-treated iNKT cell-deficient Jalpha18-/- mice restored alphaGC-induced pregnancy loss. Adoptive transfer of Treg cells downregulated alpha-GC-induced pregnancy loss in WT mice. Finally, co culture with alphaGC-stimulated decidual iNKT cells decreased the production of IL-10 and TGF-beta in decidual Treg cells and inhibited their suppressive activity. These findings suggest that activation of iNKT cells induces pregnancy loss in mice in an IFN-gamma-dependent manner. In addition, inhibition of the function of decidual Treg cells has an important role in iNKT cell-mediated pregnancy loss. PMID- 27706126 TI - RORgammat, a multitask nuclear receptor at mucosal surfaces. AB - RORgammat is a nuclear hormone receptor that has followed an exponential success carrier. Its modest origins as an orphan receptor cloned from human pancreas blossomed within 15 years into a critical regulator of anti-microbial immunity and a major target in the fight against inflammatory pathologies. Here, I review its role as a transcription factor required for the generation of type 3 lymphoid cells, which induce the development of lymphoid tissues, provide resistance of epithelial stem cells to injury, maintain homeostasis with the symbiotic microbiota, orchestrate defense against extracellular microbes, and regulate allergic responses. RORgammat is also an intriguing molecule that is regulated by the circadian rhythm and includes cholesterol metabolites as ligands. RORgammat therefore links anti-microbial immunity with circadian rhythms and steroids, the logic of which remains to be understood. PMID- 27706128 TI - Age-related spontaneous lacrimal keratoconjunctivitis is accompanied by dysfunctional T regulatory cells. AB - In both humans and animal models, the development of Sjogren syndrome (SS) and non-SS keratoconjunctivitis sicca (KCS) increases with age. Here, we investigated the ocular surface and lacrimal gland (LG) phenotype of NOD.B10.H2b mice at 7-14, 45-50, and 96-100 weeks. Aged mice develop increased corneal permeability, CD4+ T cell infiltration, and conjunctival goblet cell loss. Aged mice have LG atrophy with increased lymphocyte infiltration and inflammatory cytokine levels. An increase in the frequency of CD4+Foxp3+ T regulatory cells (Tregs) was observed with age in the cervical lymph node (CLN), spleen, and LG. These CD4+CD25+ cells lose suppressive ability, while maintaining expression of Foxp3 (forkhead box P3) and producing interleukin-17 (IL-17) and interferon-gamma (IFN-gamma). An increase of Foxp3+IL-17+ or Foxp3+IFN-gamma+ cells was observed in the LG and LG draining CLN. In adoptive transfer experiments, recipients of either purified Tregs or purified T effector cells from aged donors developed lacrimal keratoconjunctivitis, whereas recipients of young Tregs or young T effector cells failed to develop disease. Overall, these results suggest inflammatory cytokine producing CD4+Foxp3+ cells participate in the pathogenesis of age-related ocular surface disease. PMID- 27706131 TI - Where are the data? PMID- 27706130 TI - Evolution of surfactant therapy for respiratory distress syndrome: past, present, and future. AB - Respiratory distress syndrome (RDS) due to surfactant deficiency is the most common cause of respiratory failure in preterm infants. Tremendous progress has been made since the original description that surfactant deficiency is the major cause of RDS. Surfactant therapy has been extensively studied in preterm infants and has been shown to significantly decrease air leaks and neonatal and infant mortality. Synthetic and animal-derived surfactants from bovine as well as porcine origin have been evaluated in randomized controlled trials. Animal derived surfactants generally result in faster weaning of respiratory support, shorter duration of invasive ventilation, and decreased mortality when compared to first- or second-generation of synthetic surfactants, but some of the second generation synthetic surfactants are at least not inferior to the animal-derived surfactants. Using a higher initial dose of porcine derived surfactant may provide better outcomes when compared with using lower doses of bovine surfactants, likely, due to compositional difference and/or the dose. Third generation synthetic surfactant containing peptide analogs of surfactant protein B and C are currently being studied. Less invasive intra-tracheal surfactant administration techniques in spontaneously breathing neonate receiving noninvasive ventilator support are also being evaluated. In the present era, prophylactic surfactant is not recommended as it may increase the risk of lung injury or death. In the future, surfactants may be used as vector to deliver steroids, or used in combination with molecules, such as, recombinant Club Cell Protein-10 (rhCC-10) to improve pulmonary outcomes. Also, noninvasive surfactant administration techniques, such as aerosolization or atomization of surfactant may play a greater role in the future. PMID- 27706129 TI - Pediatric sickle cell disease: past successes and future challenges. AB - Once a fatal disease of childhood, more than 95% of patients born today with sickle cell disease (SCD) in developed countries are expected to survive into adulthood, largely because of improvements in supportive and preventive care (newborn screening, penicillin prophylaxis, transcranial Doppler (TCD) screening). Hydroxyurea (HU) therapy, the only oral medication currently available to prevent SCD complications, has become more widespread over the past 20 y. The NHLBI recommends that HU be offered to all patients with HbSS beginning at 9 mo of age, and the recently published Abnormal TCD with Transfusions Changing to HU (TWiTCH) trial has shown HU as an acceptable alternative to transfusion therapy for patients at high risk of stroke. While hematopoietic stem cell transplant (HSCT) is a curative option for SCD, less than 25% of patients have a suitable donor. Alternative stem cell sources from unrelated donors and haplo-identical donors are currently under investigation as are gene therapy trials. This review will focus on early efforts to elucidate SCD pathophysiology as well as supportive and preventive care improvements. Findings from recent multi-center studies (Silent Infarct Transfusion (SIT) Trial and TWiTCH) will be summarized. Finally, HSCT trials and gene therapy will be reviewed.

PMID- 27706134 TI - De novo assembly and phasing of a Korean human genome. AB - Advances in genome assembly and phasing provide an opportunity to investigate the diploid architecture of the human genome and reveal the full range of structural variation across population groups. Here we report the de novo assembly and haplotype phasing of the Korean individual AK1 (ref. 1) using single-molecule real-time sequencing, next-generation mapping, microfluidics-based linked reads, and bacterial artificial chromosome (BAC) sequencing approaches. Single-molecule sequencing coupled with next-generation mapping generated a highly contiguous assembly, with a contig N50 size of 17.9 Mb and a scaffold N50 size of 44.8 Mb, resolving 8 chromosomal arms into single scaffolds. The de novo assembly, along with local assemblies and spanning long reads, closes 105 and extends into 72 out of 190 euchromatic gaps in the reference genome, adding 1.03 Mb of previously intractable sequence. High concordance between the assembly and paired-end sequences from 62,758 BAC clones provides strong support for the robustness of the assembly. We identify 18,210 structural variants by direct comparison of the assembly with the human reference, identifying thousands of breakpoints that, to our knowledge, have not been reported before. Many of the insertions are reflected in the transcriptome and are shared across the Asian population. We performed haplotype phasing of the assembly with short reads, long reads and linked reads from whole-genome sequencing and with short reads from 31,719 BAC clones, thereby achieving phased blocks with an N50 size of 11.6 Mb. Haplotigs assembled from single-molecule real-time reads assigned to haplotypes on phased blocks covered 89% of genes. The haplotigs accurately characterized the hypervariable major histocompatability complex region as well as demonstrating allele configuration in clinically relevant genes such as CYP2D6. This work presents the most contiguous diploid human genome assembly so far, with extensive investigation of unreported and Asian-specific structural variants, and high quality haplotyping of clinically relevant alleles for precision medicine. PMID- 27706136 TI - Evidence for a limit to human lifespan. AB - Driven by technological progress, human life expectancy has increased greatly since the nineteenth century. Demographic evidence has revealed an ongoing reduction in old-age mortality and a rise of the maximum age at death, which may gradually extend human longevity. Together with observations that lifespan in various animal species is flexible and can be increased by genetic or pharmaceutical intervention, these results have led to suggestions that longevity may not be subject to strict, species-specific genetic constraints. Here, by analysing global demographic data, we show that improvements in survival with age tend to decline after age 100, and that the age at death of the world's oldest person has not increased since the 1990s. Our results strongly suggest that the maximum lifespan of humans is fixed and subject to natural constraints. PMID- 27706137 TI - Evolution of Hoxa11 regulation in vertebrates is linked to the pentadactyl state. AB - The fin-to-limb transition represents one of the major vertebrate morphological innovations associated with the transition from aquatic to terrestrial life and is an attractive model for gaining insights into the mechanisms of morphological diversity between species. One of the characteristic features of limbs is the presence of digits at their extremities. Although most tetrapods have limbs with five digits (pentadactyl limbs), palaeontological data indicate that digits emerged in lobed fins of early tetrapods, which were polydactylous. How the transition to pentadactyl limbs occurred remains unclear. Here we show that the mutually exclusive expression of the mouse genes Hoxa11 and Hoxa13, which were previously proposed to be involved in the origin of the tetrapod limb, is required for the pentadactyl state. We further demonstrate that the exclusion of Hoxa11 from the Hoxa13 domain relies on an enhancer that drives antisense transcription at the Hoxa11 locus after activation by HOXA13 and HOXD13. Finally, we show that the enhancer that drives antisense transcription of the mouse Hoxa11 gene is absent in zebrafish, which, together with the largely overlapping expression of hoxa11 and hoxa13 genes reported in fish, suggests that this enhancer emerged in the course of the fin-to-limb transition. On the basis of the polydactyly that we observed after expression of Hoxa11 in distal limbs, we propose that the evolution of Hoxa11 regulation contributed to the transition from polydactyl limbs in stem-group tetrapods to pentadactyl limbs in extant tetrapods. PMID- 27706135 TI - The epichaperome is an integrated chaperome network that facilitates tumour survival. AB - Transient, multi-protein complexes are important facilitators of cellular functions. This includes the chaperome, an abundant protein family comprising chaperones, co-chaperones, adaptors, and folding enzymes-dynamic complexes of which regulate cellular homeostasis together with the protein degradation machinery. Numerous studies have addressed the role of chaperome members in isolation, yet little is known about their relationships regarding how they interact and function together in malignancy. As function is probably highly dependent on endogenous conditions found in native tumours, chaperomes have resisted investigation, mainly due to the limitations of methods needed to disrupt or engineer the cellular environment to facilitate analysis. Such limitations have led to a bottleneck in our understanding of chaperome-related disease biology and in the development of chaperome-targeted cancer treatment. Here we examined the chaperome complexes in a large set of tumour specimens. The methods used maintained the endogenous native state of tumours and we exploited this to investigate the molecular characteristics and composition of the chaperome in cancer, the molecular factors that drive chaperome networks to crosstalk in tumours, the distinguishing factors of the chaperome in tumours sensitive to pharmacologic inhibition, and the characteristics of tumours that may benefit from chaperome therapy. We find that under conditions of stress, such as malignant transformation fuelled by MYC, the chaperome becomes biochemically 'rewired' to form a network of stable, survival-facilitating, high-molecular weight complexes. The chaperones heat shock protein 90 (HSP90) and heat shock cognate protein 70 (HSC70) are nucleating sites for these physically and functionally integrated complexes. The results indicate that these tightly integrated chaperome units, here termed the epichaperome, can function as a network to enhance cellular survival, irrespective of tissue of origin or genetic background. The epichaperome, present in over half of all cancers tested, has implications for diagnostics and also provides potential vulnerability as a target for drug intervention.

PMID- 27706140 TI - Formation of new chromatin domains determines pathogenicity of genomic duplications. AB - Chromosome conformation capture methods have identified subchromosomal structures of higher-order chromatin interactions called topologically associated domains (TADs) that are separated from each other by boundary regions. By subdividing the genome into discrete regulatory units, TADs restrict the contacts that enhancers establish with their target genes. However, the mechanisms that underlie partitioning of the genome into TADs remain poorly understood. Here we show by chromosome conformation capture (capture Hi-C and 4C-seq methods) that genomic duplications in patient cells and genetically modified mice can result in the formation of new chromatin domains (neo-TADs) and that this process determines their molecular pathology. Duplications of non-coding DNA within the mouse Sox9 TAD (intra-TAD) that cause female to male sex reversal in humans, showed increased contact of the duplicated regions within the TAD, but no change in the overall TAD structure. In contrast, overlapping duplications that extended over the next boundary into the neighbouring TAD (inter-TAD), resulted in the formation of a new chromatin domain (neo-TAD) that was isolated from the rest of the genome. As a consequence of this insulation, inter-TAD duplications had no phenotypic effect. However, incorporation of the next flanking gene, Kcnj2, in the neo-TAD resulted in ectopic contacts of Kcnj2 with the duplicated part of the Sox9 regulatory region, consecutive misexpression of Kcnj2, and a limb malformation phenotype. Our findings provide evidence that TADs are genomic regulatory units with a high degree of internal stability that can be sculptured by structural genomic variations. This process is important for the interpretation of copy number variations, as these variations are routinely detected in diagnostic tests for genetic disease and cancer. This finding also has relevance in an evolutionary setting because copy-number differences are thought to have a crucial role in the evolution of genome complexity. PMID- 27706142 TI - Metal-organic frameworks as selectivity regulators for hydrogenation reactions. AB - Owing to the limited availability of natural sources, the widespread demand of the flavouring, perfume and pharmaceutical industries for unsaturated alcohols is met by producing them from alpha,beta-unsaturated aldehydes, through the selective hydrogenation of the carbon-oxygen group (in preference to the carbon carbon group). However, developing effective catalysts for this transformation is challenging, because hydrogenation of the carbon-carbon group is thermodynamically favoured. This difficulty is particularly relevant for one major category of heterogeneous catalyst: metal nanoparticles supported on metal oxides. These systems are generally incapable of significantly enhancing the selectivity towards thermodynamically unfavoured reactions, because only the edges of nanoparticles that are in direct contact with the metal-oxide support possess selective catalytic properties; most of the exposed nanoparticle surfaces do not. This has inspired the use of metal-organic frameworks (MOFs) to encapsulate metal nanoparticles within their layers or inside their channels, to influence the activity of the entire nanoparticle surface while maintaining efficient reactant and product transport owing to the porous nature of the material. Here we show that MOFs can also serve as effective selectivity regulators for the hydrogenation of alpha,beta-unsaturated aldehydes. Sandwiching platinum nanoparticles between an inner core and an outer shell composed of an MOF with metal nodes of Fe3+, Cr3+ or both (known as MIL-101; refs 19, 20, 21) results in stable catalysts that convert a range of alpha,beta-unsaturated aldehydes with high efficiency and with significantly enhanced selectivity towards unsaturated alcohols. Calculations reveal that preferential interaction of MOF metal sites with the carbon-oxygen rather than the carbon-carbon group renders hydrogenation of the former by the embedded platinum nanoparticles a thermodynamically favoured reaction. We anticipate that our basic design strategy will allow the development of other selective heterogeneous catalysts for important yet challenging transformations.

PMID- 27706145 TI - Quantum dynamics of simultaneously measured non-commuting observables. AB - In quantum mechanics, measurements cause wavefunction collapse that yields precise outcomes, whereas for non-commuting observables such as position and momentum Heisenberg's uncertainty principle limits the intrinsic precision of a state. Although theoretical work has demonstrated that it should be possible to perform simultaneous non-commuting measurements and has revealed the limits on measurement outcomes, only recently has the dynamics of the quantum state been discussed. To realize this unexplored regime, we simultaneously apply two continuous quantum non-demolition probes of non-commuting observables to a superconducting qubit. We implement multiple readout channels by coupling the qubit to multiple modes of a cavity. To control the measurement observables, we implement a 'single quadrature' measurement by driving the qubit and applying cavity sidebands with a relative phase that sets the observable. Here, we use this approach to show that the uncertainty principle governs the dynamics of the wavefunction by enforcing a lower bound on the measurement-induced disturbance. Consequently, as we transition from measuring identical to measuring non commuting observables, the dynamics make a smooth transition from standard wavefunction collapse to localized persistent diffusion and then to isotropic persistent diffusion. Although the evolution of the state differs markedly from that of a conventional measurement, information about both non-commuting observables is extracted by keeping track of the time ordering of the measurement record, enabling quantum state tomography without alternating measurements. Our work creates novel capabilities for quantum control, including rapid state purification, adaptive measurement, measurement-based state steering and continuous quantum error correction. As physical systems often interact continuously with their environment via non-commuting degrees of freedom, our work offers a way to study how notions of contemporary quantum foundations arise in such settings. PMID- 27706146 TI - Characterisation of Reproduction-Associated Genes and Peptides in the Pest Land Snail, Theba pisana. AB - Increased understanding of the molecular components involved in reproduction may assist in understanding the evolutionary adaptations used by animals, including hermaphrodites, to produce offspring and retain a continuation of their lineage. In this study, we focus on the Mediterranean snail, Theba pisana, a hermaphroditic land snail that has become a highly invasive pest species within agricultural areas throughout the world. Our analysis of T. pisana CNS tissue has revealed gene transcripts encoding molluscan reproduction-associated proteins including APGWamide, gonadotropin-releasing hormone (GnRH) and an egg-laying hormone (ELH). ELH isoform 1 (ELH1) is known to be a potent reproductive peptide hormone involved in ovulation and egg-laying in some aquatic molluscs. Two other non-CNS ELH isoforms were also present in T. pisana (Tpi-ELH2 and Tpi-ELH3) within the snail dart sac and mucous glands. Bioactivity of a synthetic ELH1 on sexually mature T. pisana was confirmed through bioassay, with snails showing ELH1-induced egg-laying behaviours, including soil burrowing and oviposition. In summary, this study presents a detailed molecular analysis of reproductive neuropeptide genes in a land snail and provides a foundation for understanding ELH function. PMID- 27706147 TI - Spatiotemporal Dynamics and Fitness Analysis of Global Oil Market: Based on Complex Network. AB - We study the overall topological structure properties of global oil trade network, such as degree, strength, cumulative distribution, information entropy and weight clustering. The structural evolution of the network is investigated as well. We find the global oil import and export networks do not show typical scale free distribution, but display disassortative property. Furthermore, based on the monthly data of oil import values during 2005.01-2014.12, by applying random matrix theory, we investigate the complex spatiotemporal dynamic from the country level and fitness evolution of the global oil market from a demand-side analysis. Abundant information about global oil market can be obtained from deviating eigenvalues. The result shows that the oil market has experienced five different periods, which is consistent with the evolution of country clusters. Moreover, we find the changing trend of fitness function agrees with that of gross domestic product (GDP), and suggest that the fitness evolution of oil market can be predicted by forecasting GDP values. To conclude, some suggestions are provided according to the results. PMID- 27706148 TI - Calcium Stimulates Self-Assembly of Protein Kinase C alpha In Vitro. AB - Protein kinase C alpha (PKCalpha) is a nodal regulator in several intracellular signaling networks. PKCalpha is composed of modular domains that interact with each other to dynamically regulate spatial-temporal function. We find that PKCalpha specifically, rapidly and reversibly self-assembles in the presence of calcium in vitro. This phenomenon is dependent on, and can be modulated by an intramolecular interaction between the C1a and C2 protein domains of PKCalpha. Next, we monitor self-assembly of PKC-mCitrine fusion proteins using time resolved and steady-state homoFRET. HomoFRET between full-length PKCalpha molecules is observed when in solution with both calcium and liposomes containing either diacylglycerol (DAG) or phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2). Surprisingly, the C2 domain is sufficient to cluster on liposomes containing PI(4,5)P2, indicating the C1a domain is not required for self-assembly in this context. We conclude that three distinct clustered states of PKCalpha can be formed depending on what combination of cofactors are bound, but Ca2+ is minimally required and sufficient for clustering. PMID- 27706149 TI - Influenza Pandemics and Tuberculosis Mortality in 1889 and 1918: Analysis of Historical Data from Switzerland. AB - BACKGROUND: Tuberculosis (TB) mortality declined in the northern hemisphere over the last 200 years, but peaked during the Russian (1889) and the Spanish (1918) influenza pandemics. We studied the impact of these two pandemics on TB mortality. METHODS: We retrieved historic data from mortality registers for the city of Bern and countrywide for Switzerland. We used Poisson regression models to quantify the excess pulmonary TB (PTB) mortality attributable to influenza. RESULTS: Yearly PTB mortality rates increased during both influenza pandemics. Monthly influenza and PTB mortality rates peaked during winter and early spring. In Bern, for an increase of 100 influenza deaths (per 100,000 population) monthly PTB mortality rates increased by a factor of 1.5 (95%Cl 1.4-1.6, p<0.001) during the Russian, and 3.6 (95%Cl 0.7-18.0, p = 0.13) during the Spanish pandemic. Nationally, the factor was 2.0 (95%Cl 1.8-2.2, p<0.001) and 1.5 (95%Cl 1.1-1.9, p = 0.004), respectively. We did not observe any excess cancer or extrapulmonary TB mortality (as a negative control) during the influenza pandemics. CONCLUSIONS: We demonstrate excess PTB mortality during historic influenza pandemics in Switzerland, which supports a role for influenza vaccination in PTB patients in high TB incidence countries. PMID- 27706150 TI - Immediate Blood Draw for CD4+ Cell Count Is Associated with Linkage to Care in Durban, South Africa: Findings from Pathways to Engagement in HIV Care. AB - BACKGROUND: Timely linkage to care by newly-diagnosed HIV+ individuals remains a significant challenge to achieving UNAIDS 90-90-90 goals. Current World Health Organization (WHO) guidelines recommend initiating anti-retroviral treatment (ART) regardless of CD4+ count, with priority given to those with CD4+ <350 cells/MUl. We evaluated the impact of not having a day-of-diagnosis CD4+ count blood draw, as recommended by South African guidelines, on time to linkage, using data from a prospective cohort study. METHODS: Individuals (N = 2773) were interviewed prior to HIV counseling and testing at three public sector primary care clinics in the greater Durban area; 785 were newly-diagnosed and eligible for the cohort study; 459 (58.5%) joined and were followed for eight months with three structured assessments. Linkage to care, defined as returning to clinic for CD4+ count results, and day-of-diagnosis blood draw were self-reported. RESULTS: Overall, 72.5% did not have a day-of-diagnosis CD4+ count blood draw, and 19.2% of these never returned. Compared with a day-of-diagnosis blood draw, the adjusted hazard ratio of linkage (AHRlinkage) associated with not having day-of diagnosis blood draw was 0.66 (95%CI: 0.51, 0.85). By 4 months, 54.8% of those without day-of-diagnosis blood draw vs. 75.2% with one were linked to care (chi squared p = 0.004). Of those who deferred blood draw, 48.3% cited clinic-related and 51.7% cited personal reasons. AHRlinkage was 0.60 (95%CI: 0.44, 0.82) for clinic-related and 0.53 (95%CI: 0.38, 0.75) for personal reasons relative to having day-of-diagnosis blood draw. CONCLUSIONS: Newly-diagnosed HIV+ individuals who did not undergo CD4+ count blood draw on the day they were diagnosed regardless of the reason for deferring-had delayed linkage to care relative to those with same-day blood draw. To enhance prompt linkage to care even when test and treat protocols are implemented, all diagnostic testing required before ART initiation should be performed on the same day as HIV testing/diagnosis. This may require modifying clinic procedures to enable overnight blood storage if same-day draws cannot be performed, and providing additional counseling to encourage newly diagnosed individuals to complete day-of-diagnosis testing. Tracking HIV+ individuals via clinic registries should commence immediately from diagnosis to reduce these early losses to care. PMID- 27706151 TI - Mechanism of Rifampicin Inactivation in Nocardia farcinica. AB - A novel mechanism of rifampicin (Rif) resistance has recently been reported in Nocardia farcinica. This new mechanism involves the activity of rifampicin monooxygenase (RifMO), a flavin-dependent monooxygenase that catalyzes the hydroxylation of Rif, which is the first step in the degradation pathway. Recombinant RifMO was overexpressed and purified for biochemical analysis. Kinetic characterization revealed that Rif binding is necessary for effective FAD reduction. RifMO exhibits only a 3-fold coenzyme preference for NADPH over NADH. RifMO catalyzes the incorporation of a single oxygen atom forming an unstable intermediate that eventually is converted to 2'-N-hydroxy-4-oxo-Rif. Stable C4a hydroperoxyflavin was not detected by rapid kinetics methods, which is consistent with only 30% of the activated oxygen leading to product formation. These findings represent the first reported detailed biochemical characterization of a flavin-monooxygenase involved in antibiotic resistance. PMID- 27706153 TI - Critical Decline of the Eastern Caribbean Sperm Whale Population. AB - Sperm whale (Physeter macrocephalus) populations were expected to rebuild following the end of commercial whaling. We document the decline of the population in the eastern Caribbean by tracing demographic changes of well studied social units. We address hypotheses that, over a ten-year period of dedicated effort (2005-2015), unit size, numbers of calves and/or calving rates have each declined. Across 16 units, the number of adults decreased in 12 units, increased in two, and showed no change in two. The number of adults per unit decreased at -0.195 individuals/yr (95% CI: -0.080 to -0.310; P = 0.001). The number of calves also declined, but the decline was not significant. This negative trend of -4.5% per year in unit size started in about 2010, with numbers being fairly stable until then. There are several natural and anthropogenic threats, but no well-substantiated cause for the decline. PMID- 27706152 TI - The Transcriptional Signature of Active Tuberculosis Reflects Symptom Status in Extra-Pulmonary and Pulmonary Tuberculosis. AB - BACKGROUND: Mycobacterium tuberculosis infection is a leading cause of infectious death worldwide. Gene-expression microarray studies profiling the blood transcriptional response of tuberculosis (TB) patients have been undertaken in order to better understand the host immune response as well as to identify potential biomarkers of disease. To date most of these studies have focused on pulmonary TB patients with gene-expression profiles of extra-pulmonary TB patients yet to be compared to those of patients with pulmonary TB or sarcoidosis. METHODS: A novel cohort of patients with extra-pulmonary TB and sarcoidosis was recruited and the transcriptional response of these patients compared to those with pulmonary TB using a variety of transcriptomic approaches including testing a previously defined 380 gene meta-signature of active TB. RESULTS: The 380 meta-signature broadly differentiated active TB from healthy controls in this new dataset consisting of pulmonary and extra-pulmonary TB. The top 15 genes from this meta-signature had a lower sensitivity for differentiating extra-pulmonary TB from healthy controls as compared to pulmonary TB. We found the blood transcriptional responses in pulmonary and extra-pulmonary TB to be heterogeneous and to reflect the extent of symptoms of disease. CONCLUSIONS: The transcriptional signature in extra-pulmonary TB demonstrated heterogeneity of gene expression reflective of symptom status, while the signature of pulmonary TB was distinct, based on a higher proportion of symptomatic individuals. These findings are of importance for the rational design and implementation of mRNA based TB diagnostics. PMID- 27706154 TI - Volunteer Conservation Action Data Reveals Large-Scale and Long-Term Negative Population Trends of a Widespread Amphibian, the Common Toad (Bufo bufo). AB - Rare and threatened species are the most frequent focus of conservation science and action. With the ongoing shift from single-species conservation towards the preservation of ecosystem services, there is a greater need to understand abundance trends of common species because declines in common species can disproportionately impact ecosystems function. We used volunteer-collected data in two European countries, the United Kingdom (UK) and Switzerland, since the 1970s to assess national and regional trends for one of Europe's most abundant amphibian species, the common toad (Bufo bufo). Millions of toads were moved by volunteers across roads during this period in an effort to protect them from road traffic. For Switzerland, we additionally estimated trends for the common frog (Rana temporaria), a similarly widespread and common amphibian species. We used state-space models to account for variability in detection and effort and included only populations with at least 5 years of data; 153 populations for the UK and 141 for Switzerland. Common toads declined continuously in each decade in both countries since the 1980s. Given the declines, this common species almost qualifies for International Union for the Conservation of Nature (IUCN) red listing over this period despite volunteer conservation efforts. Reasons for the declines and wider impacts remain unknown. By contrast, common frog populations were stable or increasing in Switzerland, although there was evidence of declines after 2003. "Toads on Roads" schemes are vital citizen conservation action projects, and the data from such projects can be used for large scale trend estimations of widespread amphibians. We highlight the need for increased research into the status of common amphibian species in addition to conservation efforts focusing on rare and threatened species. PMID- 27706155 TI - AlignerBoost: A Generalized Software Toolkit for Boosting Next-Gen Sequencing Mapping Accuracy Using a Bayesian-Based Mapping Quality Framework. AB - Accurate mapping of next-generation sequencing (NGS) reads to reference genomes is crucial for almost all NGS applications and downstream analyses. Various repetitive elements in human and other higher eukaryotic genomes contribute in large part to ambiguously (non-uniquely) mapped reads. Most available NGS aligners attempt to address this by either removing all non-uniquely mapping reads, or reporting one random or "best" hit based on simple heuristics. Accurate estimation of the mapping quality of NGS reads is therefore critical albeit completely lacking at present. Here we developed a generalized software toolkit "AlignerBoost", which utilizes a Bayesian-based framework to accurately estimate mapping quality of ambiguously mapped NGS reads. We tested AlignerBoost with both simulated and real DNA-seq and RNA-seq datasets at various thresholds. In most cases, but especially for reads falling within repetitive regions, AlignerBoost dramatically increases the mapping precision of modern NGS aligners without significantly compromising the sensitivity even without mapping quality filters. When using higher mapping quality cutoffs, AlignerBoost achieves a much lower false mapping rate while exhibiting comparable or higher sensitivity compared to the aligner default modes, therefore significantly boosting the detection power of NGS aligners even using extreme thresholds. AlignerBoost is also SNP-aware, and higher quality alignments can be achieved if provided with known SNPs. AlignerBoost's algorithm is computationally efficient, and can process one million alignments within 30 seconds on a typical desktop computer. AlignerBoost is implemented as a uniform Java application and is freely available at https://github.com/Grice-Lab/AlignerBoost. PMID- 27706156 TI - Validation of a Rapid Rabies Diagnostic Tool for Field Surveillance in Developing Countries. AB - BACKGROUND: One root cause of the neglect of rabies is the lack of adequate diagnostic tests in the context of low income countries. A rapid, performance friendly and low cost method to detect rabies virus (RABV) in brain samples will contribute positively to surveillance and consequently to accurate data reporting, which is presently missing in the majority of rabies endemic countries. METHODOLOGY/PRINCIPAL FINDINGS: We evaluated a rapid immunodiagnostic test (RIDT) in comparison with the standard fluorescent antibody test (FAT) and confirmed the detection of the viral RNA by real time reverse transcription polymerase chain reaction (RT-qPCR). Our analysis is a multicentre approach to validate the performance of the RIDT in both a field laboratory (N'Djamena, Chad) and an international reference laboratory (Institut Pasteur, Paris, France). In the field laboratory, 48 samples from dogs were tested and in the reference laboratory setting, a total of 73 samples was tested, representing a wide diversity of RABV in terms of animal species tested (13 different species), geographical origin of isolates with special emphasis on Africa, and different phylogenetic clades. Under reference laboratory conditions, specificity was 93.3% and sensitivity was 95.3% compared to the gold standard FAT test. Under field laboratory conditions, the RIDT yielded a higher reliability than the FAT test particularly on fresh and decomposed samples. Viral RNA was later extracted directly from the test filter paper and further used successfully for sequencing and genotyping. CONCLUSION/SIGNIFICANCE: The RIDT shows excellent performance qualities both in regard to user friendliness and reliability of the result. In addition, the test cassettes can be used as a vehicle to ship viral RNA to reference laboratories for further laboratory confirmation of the diagnosis and for epidemiological investigations using nucleotide sequencing. The potential for satisfactory use in remote locations is therefore very high to improve the global knowledge of rabies epidemiology. However, we suggest some changes to the protocol, as well as careful further validation, before promotion and wider use. PMID- 27706157 TI - Differential Infectivities among Different Japanese Encephalitis Virus Genotypes in Culex quinquefasciatus Mosquitoes. AB - During the last 20 years, the epidemiology of Japanese encephalitis virus (JEV) has changed significantly in its endemic regions due to the gradual displacement of the previously dominant genotype III (GIII) with clade b of GI (GI-b). Whilst there is only limited genetic difference distinguishing the two GI clades (GI-a and GI-b), GI-b has shown a significantly wider and more rapid dispersal pattern in several regions in Asia than the GI-a clade, which remains restricted in its geographic distribution since its emergence. Although previously published molecular epidemiological evidence has shown distinct phylodynamic patterns, characterization of the two GI clades has only been limited to in vitro studies. In this study, Culex quinquefasciatus, a known competent JEV mosquito vector species, was orally challenged with three JEV strains each representing GI-a, GI b, and GIII, respectively. Infection and dissemination were determined based on the detection of infectious viruses in homogenized mosquitoes. Detection of JEV RNA in mosquito saliva at 14 days post infection indicated that Cx. quinquefasciatus can be a competent vector species for both GI and GIII strains. Significantly higher infection rates in mosquitoes exposed to the GI-b and GIII strains than the GI-a strain suggest infectivity in arthropod vectors may lead to the selective advantage of previously and currently dominant genotypes. It could thus play a role in enzootic transmission cycles for the maintenance of JEV if this virus were ever to be introduced into North America. PMID- 27706158 TI - Colorimetric Detection of Plasmodium vivax in Urine Using MSP10 Oligonucleotides and Gold Nanoparticles. AB - Plasmodium vivax is the most prevalent cause of human malaria in the world and can lead to severe disease with high potential for relapse. Its genetic and geographic diversities make it challenging to control. P. vivax is understudied and to achieve control of malaria in endemic areas, a rapid, accurate, and simple diagnostic tool is necessary. In this pilot study, we found that a colorimetric system using AuNPs and MSP10 DNA detection in urine can provide fast, easy, and inexpensive identification of P. vivax. The test exhibited promising sensitivity (84%), high specificity (97%), and only mild cross-reactivity with P. falciparum (21%). It is simple to use, with a visible color change that negates the need for a spectrometer, making it suitable for use in austere conditions. Using urine eliminates the need for finger-prick, increasing both the safety profile and patient acceptance of this model. PMID- 27706160 TI - Sexual Dysfunction in Type 2 Diabetes at Diagnosis: Progression over Time and Drug and Non-Drug Correlated Factors. AB - AIMS: To present the longitudinal data of the SUBITO-DE study, a prospective survey involving male patients with new or recently diagnosed type 2 diabetes mellitus (T2DM) (<24 months). MATERIALS AND METHODS: Sexual function was assessed in male patients with T2DM at baseline (phase 1) and after a mean follow-up of 18 months (phase 2). Standard metabolic parameters and sexual and depressive symptoms were evaluated. RESULTS: Six of the 499 enrolled patients died of different causes during phase 1. Of the 493 surviving men invited to participate in phase 2, 450 (mean age 59.0+/-9.0 years) (90.2%) accepted and 43 (8.2%) were lost to follow-up. As compared to baseline, the proportion of the men who reported improvement in erectile dysfunction (ED) at follow-up was nearly double that of the men who reported worsening of ED (22.6% vs. 12.8%). The increase in frequency of sexual activity the men reported at follow-up assessment indicates that many never treated before baseline were taking an ED drug during the study period (106 subjects). Phosphodiesterase type 5 inhibitors (PDE5i) were the ED drugs most commonly taken at both baseline and follow-up. An overall improvement over baseline values was observed in metabolic targets for T2DM and depressive symptoms. Conversely, no change in lifestyle behaviors was recorded during the study. CONCLUSIONS: Sexual dysfunction is a major concern in men with T2DM. The SUBITO-DE study demonstrates that, when combined with adequate counseling and tailored PDE5i therapy, an integrated approach to achieving metabolic targets in men with T2DM can improve sexual function as well as depressive symptoms. PMID- 27706159 TI - Molecular Detection of Tick-Borne Pathogens in Humans with Tick Bites and Erythema Migrans, in the Netherlands. AB - BACKGROUND: Tick-borne diseases are the most prevalent vector-borne diseases in Europe. Knowledge on the incidence and clinical presentation of other tick-borne diseases than Lyme borreliosis and tick-borne encephalitis is minimal, despite the high human exposure to these pathogens through tick bites. Using molecular detection techniques, the frequency of tick-borne infections after exposure through tick bites was estimated. METHODS: Ticks, blood samples and questionnaires on health status were collected from patients that visited their general practitioner with a tick bite or erythema migrans in 2007 and 2008. The presence of several tick-borne pathogens in 314 ticks and 626 blood samples of this cohort were analyzed using PCR-based methods. Using multivariate logistic regression, associations were explored between pathogens detected in blood and self-reported symptoms at enrolment and during a three-month follow-up period. RESULTS: Half of the ticks removed from humans tested positive for Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum, Candidatus Neoehrlichia mikurensis, Rickettsia helvetica, Rickettsia monacensis, Borrelia miyamotoi and several Babesia species. Among 92 Borrelia burgdorferi s. l. positive ticks, 33% carried another pathogen from a different genus. In blood of sixteen out of 626 persons with tick bites or erythema migrans, DNA was detected from Candidatus Neoehrlichia mikurensis (n = 7), Anaplasma phagocytophilum (n = 5), Babesia divergens (n = 3), Borrelia miyamotoi (n = 1) and Borrelia burgdorferi s. l. (n = 1). None of these sixteen individuals reported any overt symptoms that would indicate a corresponding illness during the three-month follow-up period. No associations were found between the presence of pathogen DNA in blood and; self reported symptoms, with pathogen DNA in the corresponding ticks (n = 8), reported tick attachment duration, tick engorgement, or antibiotic treatment at enrolment. CONCLUSIONS: Based on molecular detection techniques, the probability of infection with a tick-borne pathogen other than Lyme spirochetes after a tick bite is roughly 2.4%, in the Netherlands. Similarly, among patients with erythema migrans, the probability of a co-infection with another tick-borne pathogen is approximately 2.7%. How often these infections cause disease symptoms or to what extend co-infections affect the course of Lyme borreliosis needs further investigations.

AB - BACKGROUND: The outbreak of Zika virus (ZIKV) in the Americas has transformed a previously obscure mosquito-transmitted arbovirus of the Flaviviridae family into a major public health concern. Little is currently known about the evolution and biology of ZIKV and the factors that contribute to the associated pathogenesis. Determining genomic sequences of clinical viral isolates and characterization of elements within these are an important prerequisite to advance our understanding of viral replicative processes and virus-host interactions. METHODOLOGY/PRINCIPAL FINDINGS: We obtained a ZIKV isolate from a patient who presented with classical ZIKV-associated symptoms, and used high throughput sequencing and other molecular biology approaches to determine its full genome sequence, including non-coding regions. Genome regions were characterized and compared to the sequences of other isolates where available. Furthermore, we identified a subgenomic flavivirus RNA (sfRNA) in ZIKV-infected cells that has antagonist activity against RIG-I induced type I interferon induction, with a lesser effect on MDA-5 mediated action. CONCLUSIONS/SIGNIFICANCE: The full-length genome sequence including non-coding regions of a South American ZIKV isolate from a patient with classical symptoms will support efforts to develop genetic tools for this virus. Detection of sfRNA that counteracts interferon responses is likely to be important for further understanding of pathogenesis and virus-host interactions. PMID- 27706162 TI - Controlling Neglected Tropical Diseases (NTDs) in Haiti: Implementation Strategies and Evidence of Their Success. AB - Lymphatic filariasis (LF) and soil-transmitted helminths (STH) have been targeted since 2000 in Haiti, with a strong mass drug administration (MDA) program led by the Ministry of Public Health and Population and its collaborating international partners. By 2012, Haiti's neglected tropical disease (NTD) program had reached full national scale, and with such consistently good epidemiological coverage that it is now able to stop treatment for LF throughout almost all of the country. Essential to this success have been in the detail of how MDAs were implemented. These key programmatic elements included ensuring strong community awareness through an evidence-based, multi-channel communication and education campaign facilitated by voluntary drug distributors; strengthening community trust of the drug distributors by ensuring that respected community members were recruited and received appropriate training, supervision, identification, and motivation; enforcing a "directly observed treatment" strategy; providing easy access to treatment though numerous distribution posts and a strong drug supply chain; and ensuring quality data collection that was used to guide and inform MDA strategies. The evidence that these strategies were effective lies in both the high treatment coverage obtained- 100% geographical coverage reached in 2012, with almost all districts consistently achieving well above the epidemiological coverage targets of 65% for LF and 75% for STH-and the significant reduction in burden of infection- 45 communes having reached the target threshold for stopping treatment for LF. By taking advantage of sustained international financial and technical support, especially during the past eight years, Haiti's very successful MDA campaign resulted in steady progress toward LF elimination and development of a strong foundation for ongoing STH control. These efforts, as described, have not only helped establish the global portfolio of "best practices" for NTD control but also are poised to help solve two of the most important future NTD challenges-how to maintain control of STH infections after the community-based LF "treatment platform" ceases and how to ensure appropriate morbidity management for patients currently suffering from lymphatic filarial disease. PMID- 27706163 TI - A Motor-Gradient and Clustering Model of the Centripetal Motility of MTOCs in Meiosis I of Mouse Oocytes. AB - Asters nucleated by Microtubule (MT) organizing centers (MTOCs) converge on chromosomes during spindle assembly in mouse oocytes undergoing meiosis I. Time lapse imaging suggests that this centripetal motion is driven by a biased 'search and-capture' mechanism. Here, we develop a model of a random walk in a drift field to test the nature of the bias and the spatio-temporal dynamics of the search process. The model is used to optimize the spatial field of drift in simulations, by comparison to experimental motility statistics. In a second step, this optimized gradient is used to determine the location of immobilized dynein motors and MT polymerization parameters, since these are hypothesized to generate the gradient of forces needed to move MTOCs. We compare these scenarios to self organized mechanisms by which asters have been hypothesized to find the cell center- MT pushing at the cell-boundary and clustering motor complexes. By minimizing the error between simulation outputs and experiments, we find a model of "pulling" by a gradient of dynein motors alone can drive the centripetal motility. Interestingly, models of passive MT based "pushing" at the cortex, clustering by cross-linking motors and MT-dynamic instability gradients alone, by themselves do not result in the observed motility. The model predicts the sensitivity of the results to motor density and stall force, but not MTs per aster. A hybrid model combining a chromatin-centered immobilized dynein gradient, diffusible minus-end directed clustering motors and pushing at the cell cortex, is required to comprehensively explain the available data. The model makes experimentally testable predictions of a spatial bias and self-organized mechanisms by which MT asters can find the center of a large cell. PMID- 27706164 TI - Large Variations in HIV-1 Viral Load Explained by Shifting-Mosaic Metapopulation Dynamics. AB - The viral population of HIV-1, like many pathogens that cause systemic infection, is structured and differentiated within the body. The dynamics of cellular immune trafficking through the blood and within compartments of the body has also received wide attention. Despite these advances, mathematical models, which are widely used to interpret and predict viral and immune dynamics in infection, typically treat the infected host as a well-mixed homogeneous environment. Here, we present mathematical, analytical, and computational results that demonstrate that consideration of the spatial structure of the viral population within the host radically alters predictions of previous models. We study the dynamics of virus replication and cytotoxic T lymphocytes (CTLs) within a metapopulation of spatially segregated patches, representing T cell areas connected by circulating blood and lymph. The dynamics of the system depend critically on the interaction between CTLs and infected cells at the within-patch level. We show that for a wide range of parameters, the system admits an unexpected outcome called the shifting-mosaic steady state. In this state, the whole body's viral population is stable over time, but the equilibrium results from an underlying, highly dynamic process of local infection and clearance within T-cell centers. Notably, and in contrast to previous models, this new model can explain the large differences in set-point viral load (SPVL) observed between patients and their distribution, as well as the relatively low proportion of cells infected at any one time, and alters the predicted determinants of viral load variation. PMID- 27706165 TI - Leprosy Drug Resistance Surveillance in Colombia: The Experience of a Sentinel Country. AB - An active search for Mycobacterium leprae drug resistance was carried out, 243 multibacillary patients from endemic regions of Colombia were included from 2004 to 2013 in a surveillance program. This program was a World Health Organization initiative for drug resistance surveillance in leprosy, where Colombia is a sentinel country. M. leprae DNA from slit skin smear and/or skin biopsy samples was amplified and sequenced to identify mutations in the drug resistance determining region (DRDR) in rpoB, folP1, gyrA, and gyrB, the genes responsible for rifampicin, dapsone and ofloxacin drug-resistance, respectively. Three isolates exhibited mutations in the DRDR rpoB gene (Asp441Tyr, Ser456Leu, Ser458Met), two in the DRDR folP1 gene (Thr53Ala, Pro55Leu), and one isolate exhibited mutations in both DRDR rpoB (Ser456Met) and DRDR folP1 (Pro55Leu), suggesting multidrug resistance. One isolate had a double mutation in folP1 (Thr53Ala and Thr88Pro). Also, we detected mutations outside of DRDR that required in vivo evaluation of their association or not with drug resistance: rpoB Arg505Trp, folP1 Asp91His, Arg94Trp, and Thr88Pro, and gyrA Ala107Leu. Seventy percent of M. leprae mutations were related to drug resistance and were isolated from relapsed patients; the likelihood of relapse was significantly associated with the presence of confirmed resistance mutations (OR range 20.1 88.7, p < 0.05). Five of these relapsed patients received dapsone monotherapy as a primary treatment. In summary, the current study calls attention to M. leprae resistance in Colombia, especially the significant association between confirmed resistance mutations and relapse in leprosy patients. A high frequency of DRDR mutations for rifampicin was seen in a region where dapsone monotherapy was used extensively. PMID- 27706166 TI - Metastable Features of Economic Networks and Responses to Exogenous Shocks. AB - It is well known that a network structure plays an important role in addressing a collective behavior. In this paper we study a network of firms and corporations for addressing metastable features in an Ising based model. In our model we observe that if in a recession the government imposes a demand shock to stimulate the network, metastable features shape its response. Actually we find that there exists a minimum bound where any demand shock with a size below it is unable to trigger the market out of recession. We then investigate the impact of network characteristics on this minimum bound. We surprisingly observe that in a Watts Strogatz network, although the minimum bound depends on the average of the degrees, when translated into the language of economics, such a bound is independent of the average degrees. This bound is about 0.44DeltaGDP, where DeltaGDP is the gap of GDP between recession and expansion. We examine our suggestions for the cases of the United States and the European Union in the recent recession, and compare them with the imposed stimulations. While the stimulation in the US has been above our threshold, in the EU it has been far below our threshold. Beside providing a minimum bound for a successful stimulation, our study on the metastable features suggests that in the time of crisis there is a "golden time passage" in which the minimum bound for successful stimulation can be much lower. Hence, our study strongly suggests stimulations to arise within this time passage. PMID- 27706167 TI - Quantifying Heterogeneity in Host-Vector Contact: Tsetse (Glossina swynnertoni and G. pallidipes) Host Choice in Serengeti National Park, Tanzania. AB - BACKGROUND: Identifying hosts of blood-feeding insect vectors is crucial in understanding their role in disease transmission. Rhodesian human African trypanosomiasis (rHAT), also known as acute sleeping sickness is caused by Trypanosoma brucei rhodesiense and transmitted by tsetse flies. The disease is commonly associated with wilderness areas of east and southern Africa. Such areas hold a diverse range of species which form communities of hosts for disease maintenance. The relative importance of different wildlife hosts remains unclear. This study quantified tsetse feeding preferences in a wilderness area of great host species richness, Serengeti National Park, Tanzania, assessing tsetse feeding and host density contemporaneously. METHODS: Glossina swynnertoni and G. pallidipes were collected from six study sites. Bloodmeal sources were identified through matching Cytochrome B sequences amplified from bloodmeals from recently fed flies to published sequences. Densities of large mammal species in each site were quantified, and feeding indices calculated to assess the relative selection or avoidance of each host species by tsetse. RESULTS: The host species most commonly identified in G. swynnertoni bloodmeals, warthog (94/220), buffalo (48/220) and giraffe (46/220), were found at relatively low densities (3-11/km2) and fed on up to 15 times more frequently than expected by their relative density. Wildebeest, zebra, impala and Thomson's gazelle, found at the highest densities, were never identified in bloodmeals. Commonly identified hosts for G. pallidipes were buffalo (26/46), giraffe (9/46) and elephant (5/46). CONCLUSIONS: This study is the first to quantify tsetse host range by molecular analysis of tsetse diet with simultaneous assessment of host density in a wilderness area. Although G. swynnertoni and G. pallidipes can feed on a range of species, they are highly selective. Many host species are rarely fed on, despite being present in areas where tsetse are abundant. These feeding patterns, along with the ability of key host species to maintain and transmit T. b. rhodesiense, drive the epidemiology of rHAT in wilderness areas. PMID- 27706168 TI - Unveiling the Hidden Bat Diversity of a Neotropical Montane Forest. AB - Mountain environments, characterized by high levels of endemism, are at risk of experiencing significant biodiversity loss due to current trends in global warming. While many acknowledge their importance and vulnerability, these ecosystems still remain poorly studied, particularly for taxa that are difficult to sample such as bats. Aiming to estimate the amount of cryptic diversity among bats of a Neotropical montane cloud forest in Talamanca Range-south-east Central America-, we performed a 15-night sampling campaign, which resulted in 90 captured bats belonging to 8 species. We sequenced their mitochondrial cytochrome c oxidase subunit I (COI) and screened their inter- and intraspecific genetic variation. Phylogenetic relations with conspecifics and closely related species from other geographic regions were established using Maximum Likelihood and Bayesian inference methods, as well as median-joining haplotype networks. Mitochondrial lineages highly divergent from hitherto characterized populations (> 9% COI dissimilarity) were found in Myotis oxyotus and Hylonycteris underwoodi. Sturnira burtonlimi and M. keaysi also showed distinct mitochondrial structure with sibling species and/or populations. These results suggest that mountains in the region hold a high degree of endemicity potential that has previously been ignored in bats. They also warn of the high extinction risk montane bats may be facing due to climatic change, particularly in isolated mountain systems like Talamanca Range. PMID- 27706169 TI - Magnitude of Birth Defects in Central and Northwest Ethiopia from 2010-2014: A Descriptive Retrospective Study. AB - BACKGROUND: Birth defects are defined as structural and functional defects that develop during the organogenesis period and present at birth or detected later in life. They are one of the leading causes of infant and child mortality, morbidity, and long term disability. The magnitude of birth defects varies from country to country and from race/ethnicity to race/ethnicity, and about 40-60% of their causes are unknown. The known causes of birth defects are genetic and environmental factors which may be prevented. For various reasons, there is lack of data and research on birth defects in Ethiopia. OBJECTIVE: The major objective of this study is to estimate the magnitude of birth defects in Ethiopia. SUBJECT AND METHODS: A hospital based, retrospective, cross sectional, descriptive study was conducted. The subjects were babies/children aged 0-17years who visited selected hospitals between 2010 and 2014. Fourteen hospitals (8 in Addis Ababa, 6 in Amhara Region) were selected purposively based on case load. A data retrieving form was developed to extract relevant information from record books. RESULTS: In the hospitals mentioned, 319,776 various medical records of children aged 0 17years were found. Of these, 6,076 (1.9% with 95% CI: 1.85%-1.95%) children were diagnosed as having birth defects. The majority (58.5%) of the children were male and 41.5% female. A slightly more than half (51.1%) of the children were urban dwellers, while 48.9% were from rural areas. Among the participants of the study the proportion of birth defects ranged as follows: orofacial (34.2%), neural tube (30.8%), upper and lower limb (12.8%), cardiovascular system (10.3%), digestive system and abdominal wall (4.8%), unspecified congenital malformations (2.5%), Down syndrome (2%), genitourinary system (2%), head, face, and neck defects (0.4%), and others (0.3%). The trend of birth defects increased linearly over time [Extended Mantel-Haenszel chi square for linear trend = 356.7 (P<0.0001)]. About 275 (4.5%) of the cases had multiple (associated) birth defects and 5,801 (95.5%) isolated (single) birth defects. Out of the total birth defects, 6,018 (99%) were major and 58 (1%) minor. CONCLUSION: The magnitude of birth defects increased from 2010-2014. Orofacial and neural tube defects contributed about two thirds of the birth defects. There is an urgent need for registry and surveillance system strategies for intervention and control of birth defects in Ethiopia. PMID- 27706170 TI - Retrospective Analysis of Serotype Switching of Vibrio cholerae O1 in a Cholera Endemic Region Shows It Is a Non-random Process. AB - Genomic data generated from clinical Vibrio cholerae O1 isolates collected over a five year period in an area of Kolkata, India with seasonal cholera outbreaks allowed a detailed genetic analysis of serotype switching that occurred from Ogawa to Inaba and back to Ogawa. The change from Ogawa to Inaba resulted from mutational disruption of the methyltransferase encoded by the wbeT gene. Re emergence of the Ogawa serotype was found to result either from expansion of an already existing Ogawa clade or reversion of the mutation in an Inaba clade. Our data suggests that such transitions are not random events but rather driven by as yet unidentified selection mechanisms based on differences in the structure of the O1 antigen or in the serotype-determining wbeT gene. PMID- 27706171 TI - The Eco-epidemiology of Pacific Coast Tick Fever in California. AB - Rickettsia philipii (type strain "Rickettsia 364D"), the etiologic agent of Pacific Coast tick fever (PCTF), is transmitted to people by the Pacific Coast tick, Dermacentor occidentalis. Following the first confirmed human case of PCTF in 2008, 13 additional human cases have been reported in California, more than half of which were pediatric cases. The most common features of PCTF are the presence of at least one necrotic lesion known as an eschar (100%), fever (85%), and headache (79%); four case-patients required hospitalization and four had multiple eschars. Findings presented here implicate the nymphal or larval stages of D. occidentalis as the primary vectors of R. philipii to people. Peak transmission risk from ticks to people occurs in late summer. Rickettsia philipii DNA was detected in D. occidentalis ticks from 15 of 37 California counties. Similarly, non-pathogenic Rickettsia rhipicephali DNA was detected in D. occidentalis in 29 of 38 counties with an average prevalence of 12.0% in adult ticks. In total, 5,601 ticks tested from 2009 through 2015 yielded an overall R. philipii infection prevalence of 2.1% in adults, 0.9% in nymphs and a minimum infection prevalence of 0.4% in larval pools. Although most human cases of PCTF have been reported from northern California, acarological surveillance suggests that R. philipii may occur throughout the distribution range of D. occidentalis. PMID- 27706172 TI - An Easy Phylogenetically Informative Method to Trace the Globally Invasive Potamopyrgus Mud Snail from River's eDNA. AB - Potamopyrgus antipodarum (New Zealand mud snail) is a prosobranch mollusk native to New Zealand with a wide invasive distribution range. Its non-indigenous populations are reported from Australia, Asia, Europe and North America. Being an extremely tolerant species, Potamopyrgus is capable to survive in a great range of salinity and temperature conditions, which explains its high invasiveness and successful spread outside the native range. Here we report the first finding of Potamopyrgus antipodarum in a basin of the Cantabrian corridor in North Iberia (Bay of Biscay, Spain). Two haplotypes already described in Europe were found in different sectors of River Nora (Nalon basin), suggesting the secondary introductions from earlier established invasive populations. To enhance the surveillance of the species and tracking its further spread in the region, we developed a specific set of primers for the genus Potamopyrgus that amplify a fragment of 16S rDNA. The sequences obtained from PCR on DNA extracted from tissue and water samples (environmental DNA, eDNA) were identical in each location, suggesting clonal reproduction of the introduced individuals. Multiple introduction events from different source populations were inferred from our sequence data. The eDNA tool developed here can serve for tracing New Zealand mud snail populations outside its native range, and for inventorying mud snail population assemblages in the native settings if high throughput sequencing methodologies are employed. PMID- 27706173 TI - A Complete Fossil-Calibrated Phylogeny of Seed Plant Families as a Tool for Comparative Analyses: Testing the 'Time for Speciation' Hypothesis. AB - Explaining the uneven distribution of species richness across the branches of the tree of life has been a major challenge for evolutionary biologists. Advances in phylogenetic reconstruction, allowing the generation of large, well-sampled, phylogenetic trees have provided an opportunity to contrast competing hypotheses. Here, we present a new time-calibrated phylogeny of seed plant families using Bayesian methods and 26 fossil calibrations. While there are various published phylogenetic trees for plants which have a greater density of species sampling, we are still a long way from generating a complete phylogeny for all ~300,000+ plants. Our phylogeny samples all seed plant families and is a useful tool for comparative analyses. We use this new phylogenetic hypothesis to contrast two alternative explanations for differences in species richness among higher taxa: time for speciation versus ecological limits. We calculated net diversification rate for each clade in the phylogeny and assessed the relationship between clade age and species richness. We then fit models of speciation and extinction to individual branches in the tree to identify major rate-shifts. Our data suggest that the majority of lineages are diversifying very slowly while a few lineages, distributed throughout the tree, are diversifying rapidly. Diversification is unrelated to clade age, no matter the age range of the clades being examined, contrary to both the assumption of an unbounded lineage increase through time, and the paradigm of fixed ecological limits. These findings are consistent with the idea that ecology plays a role in diversification, but rather than imposing a fixed limit, it may have variable effects on per lineage diversification rates through time. PMID- 27706174 TI - The Performance of the Vaginal Discharge Syndromic Management in Treating Vaginal and Cervical Infection: A Systematic Review and Meta-Analysis. AB - BACKGROUND: This review aimed to synthesize and analyze the diagnostic accuracy and the likelihood of providing correct treatment of the syndromic approach Vaginal Discharge Flowchart in managing cervical infections caused by Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT), and vaginal infections caused by Trichomonas vaginalis (TV) and Bacterial vaginosis (BV) and Candida albicans. This review will inform updating the WHO 2003 guidelines on Vaginal Discharge syndromic case management. METHODS: A systematic review was conducted on published studies from 01-01-2000 to 30-03-2015 in multiple databases. Studies evaluating the diagnostic accuracy and validation of the WHO Vaginal Discharge Flowchart were included. Validation parameters including sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) and the 95% confidence intervals for the different types of the flowchart were taken as outcomes, re-calculated, and analysed using a fixed model meta-analysis for data pooling. The level of agreement between the index and reference test were determined by the Cohen's Kappa co-efficiency test. Each individual study was assessed on quality using the QUADAS-2 tool. FINDINGS: The search yielded 2,845 studies of which 16 met the eligibility criteria for final analysis. The diagnostic performance to identify cervical infections was low and resulted in a high proportion of over and missed treatment. The four flowcharts had a sensitivity between 27.37% in history and risk assessment and 90.13% with microscopy, with the inverse in specificity rates. The treatment performances between the flowcharts were inconsistent. The same applies to the use of vaginal discharge flowchart for treating vaginal infections. For vaginal infections the vaginal discharge flowchart had a good performance in flowchart 3 with 91.68% of sensitivity; 99.97% specificity; 99.93% PPV and 0.02% who missed their treatment and 8.32% of women who were over treated by the vaginal discharge flowchart. CONCLUSION: The vaginal discharge flowchart should focus on management of vaginal infection. It could be used as an intermediate approach for cervical infections for sex workers until a point of care test is available in resource poor settings. PMID- 27706175 TI - The Production of a Stable Infliximab Powder: The Evaluation of Spray and Freeze Drying for Production. AB - In prospect of developing an oral dosage form of Infliximab, for treatment of Crohn's disease and rheumatoid arthritis, freeze-drying (vial vs Lyoguard trays) and spray-drying were investigated as production method for stable powders. Dextran and inulin were used in combination with sucrose as stabilizing excipients. The drying processes did not affect Infliximab in these formulations, i.e. both the physical integrity and biological activity (TNF binding) were retained. Accelerated stability studies (1 month at 60 degrees C) showed that the TNF binding ability of Infliximab was conserved in the freeze-dried formulations, whereas the liquid counterpart lost all TNF binding. After thermal treatment, the dried formulations showed some chemical modification of the IgG in the dextran sucrose formulation, probably due to Maillard reaction products. This study indicates that, with the appropriate formulation, both spray-drying and freeze drying may be useful for (bulk) powder production of Infliximab. PMID- 27706176 TI - Sensitivity of Seven Diverse Species to Blue and Green Light: Interactions with Photon Flux. AB - Despite decades of research, the effects of spectral quality on plant growth, and development are not well understood. Much of our current understanding comes from studies with daily integrated light levels that are less than 10% of summer sunlight thus making it difficult to characterize interactions between light quality and quantity. Several studies have reported that growth is increased under fluorescent lamps compared to mixtures of wavelengths from LEDs. Conclusions regarding the effect of green light fraction range from detrimental to beneficial. Here we report the effects of eight blue and green light fractions at two photosynthetic photon fluxes (PPF; 200 and 500 MUmol m-2 s-1; with a daily light integral of 11.5 and 29 mol m-2 d-1) on growth (dry mass), leaf expansion, stem and petiole elongation, and whole-plant net assimilation of seven diverse plant species. The treatments included cool, neutral, and warm white LEDs, and combinations of blue, green and/or red LEDs. At the higher PPF (500), increasing blue light in increments from 11 to 28% reduced growth in tomato, cucumber, and pepper by 22, 26, and 14% respectively, but there was no statistically significant effect on radish, soybean, lettuce or wheat. At the lower PPF (200), increasing blue light reduced growth only in tomato (41%). The effects of blue light on growth were mediated by changes in leaf area and radiation capture, with minimal effects on whole-plant net-assimilation. In contrast to the significant effects of blue light, increasing green light in increments from 0 to 30% had a relatively small effect on growth, leaf area and net assimilation at either low or high PPF. Surprisingly, growth of three of the seven species was not reduced by a treatment with 93% green light compared to the broad spectrum treatments. Collectively, these results are consistent with a shade avoidance response associated with either low blue or high green light fractions. PMID- 27706177 TI - Real-Time Shear Wave versus Transient Elastography for Predicting Fibrosis: Applicability, and Impact of Inflammation and Steatosis. A Non-Invasive Comparison. AB - BACKGROUND AND AIMS: Real-time shear wave elastography (2D-SWE) is a two dimensional transient elastography and a competitor as a biomarker of liver fibrosis in comparison with the standard reference transient elastography by M probe (TE-M). The aims were to compare several criteria of applicability, and to assess inflammation and steatosis impact on elasticity values, two unmet needs. METHODS: We took FibroTest as the fibrosis reference and ActiTest and SteatoTest as quantitative estimates of inflammation and steatosis. After standardization of estimates, analyses used curve fitting, quantitative Lin concordance coefficient [LCC], and multivariate logistic regression. RESULTS: A total of 2,251 consecutive patients were included. We validated the predetermined 0.2 kPa cut off as a too low minimal elasticity value identifying not-reliable 2D-SWE results (LCC with FibroTest = 0.0281[-0.119;0.175]. Other criteria, elasticity CV, body mass index and depth of measures were not sufficiently discriminant. The applicability of 2D-SWE (95%CI) 89.6%(88.2-90.8), was significantly higher than that of TE, 85.6%(84.0-87.0; P<0.0001). In patients with non-advanced fibrosis (METAVIR F0F1F2), elasticity values estimated by 2D-SWE was less impacted by inflammation and steatosis than elasticity value estimated by TE-M: LCC (95%CI) 0.039 (0.021;0.058) vs 0.090 (0.068;0.112;P<0.01) and 0.105 (0.068;0.141) vs 0.192 (0.153;0.230; P<0.01) respectively. The three analyses methods gave similar results. CONCLUSIONS: Elasticity results including very low minimal signal in the region of interest should be considered not reliable. 2D-SWE had a higher applicability than TE, the reference elastography, with less impact of inflammation and steatosis especially in patients with non-advanced fibrosis, as presumed by blood tests. TRIAL REGISTRATION: ClinicalTrials.gov NCT01927133. PMID- 27706178 TI - Habitat Discontinuities Separate Genetically Divergent Populations of a Rocky Shore Marine Fish. AB - Habitat fragmentation has been suggested to be responsible for major genetic differentiations in a range of marine organisms. In this study, we combined genetic data and environmental information to unravel the relative role of geography and habitat heterogeneity on patterns of genetic population structure of corkwing wrasse (Symphodus melops), a rocky shore species at the northern limit of its distribution range in Scandinavia. Our results revealed a major genetic break separating populations inhabiting the western and southern coasts of Norway. This genetic break coincides with the longest stretch of sand in the whole study area, suggesting habitat fragmentation as a major driver of genetic differentiation of this obligate rocky shore benthic fish in Scandinavia. The complex fjords systems extending along the western coast of Norway appeared responsible for further regional genetic structuring. Our findings indicate that habitat discontinuities may lead to significant genetic fragmentation over short geographical distances, even for marine species with a pelagic larval phase, as for this rocky shore fish. PMID- 27706179 TI - Noninvasive Imaging of Human Atrial Activation during Atrial Flutter and Normal Rhythm from Body Surface Potential Maps. AB - BACKGROUND: Knowledge of atrial electrophysiological properties is crucial for clinical intervention of atrial arrhythmias and the investigation of the underlying mechanism. This study aims to evaluate the feasibility of a novel noninvasive cardiac electrical imaging technique in imaging bi-atrial activation sequences from body surface potential maps (BSPMs). METHODS: The study includes 7 subjects, with 3 atrial flutter patients, and 4 healthy subjects with normal atrial activations. The subject-specific heart-torso geometries were obtained from MRI/CT images. The equivalent current densities were reconstructed from 208 channel BSPMs by solving the inverse problem using individual heart-torso geometry models. The activation times were estimated from the time instant corresponding to the highest peak in the time course of the equivalent current densities. To evaluate the performance, a total of 32 cycles of atrial flutter were analyzed. The imaged activation maps obtained from single beats were compared with the average maps and the activation maps measured from CARTO, by using correlation coefficient (CC) and relative error (RE). RESULTS: The cardiac electrical imaging technique is capable of imaging both focal and reentrant activations. The imaged activation maps for normal atrial activations are consistent with findings from isolated human hearts. Activation maps for isthmus dependent counterclockwise reentry were reconstructed on three patients with typical atrial flutter. The method was capable of imaging macro counterclockwise reentrant loop in the right atrium and showed inter-atria electrical conduction through coronary sinus. The imaged activation sequences obtained from single beats showed good correlation with both the average activation maps (CC = 0.91+/ 0.03, RE = 0.29+/-0.05) and the clinical endocardial findings using CARTO (CC = 0.70+/-0.04, RE = 0.42+/-0.05). CONCLUSIONS: The noninvasive cardiac electrical imaging technique is able to reconstruct complex atrial reentrant activations and focal activation patterns in good consistency with clinical electrophysiological mapping. It offers the potential to assist in radio-frequency ablation of atrial arrhythmia and help defining the underlying arrhythmic mechanism.

AB - Increasing trade between countries and gains in income have given consumers around the world access to a richer and more diverse set of commercial plant products (i.e., foods and fibers produced by farmers). According to the economic theory of comparative advantage, countries open to trade will be able to consume more-in terms of volume and diversity-if they concentrate production on commodities that they can most cost-effectively produce, while importing goods that are expensive to produce, relative to other countries. Here, we perform a global analysis of traded commercial plant products and find little evidence that increasing globalization has incentivized agricultural specialization. Instead, a country's plant production and consumption patterns are still largely determined by local evolutionary legacies of plant diversification. Because tropical countries harbor a greater diversity of lineages across the tree of life than temperate countries, tropical countries produce and consume a greater diversity of plant products than do temperate countries. In contrast, the richer and more economically advanced temperate countries have the capacity to produce and consume more plant species than the generally poorer tropical countries, yet this collection of plant species is drawn from fewer branches on the tree of life. Why have countries not increasingly specialized in plant production despite the theoretical financial incentive to do so? Potential explanations include the persistence of domestic agricultural subsidies that distort production decisions, cultural preferences for diverse local food production, and that diverse food production protects rural households in developing countries from food price shocks. Less specialized production patterns will make crop systems more resilient to zonal climatic and social perturbations, but this may come at the expense of global crop production efficiency, an important step in making the transition to a hotter and more crowded world.

AB - Our objective is to study the relationship between the regulatory proteins Bcl 2/Bax and mitochondria-mediated apoptosis during the differentiation of adipose derived stromal cells (ADSCs) into neurons. Immunocytochemistry and western blotting showed that the cells weakly expressed neuron-specific enolase (NSE) in the non-induced group and expressed NSE more strongly in the groups induced for 1 h, 3 h, 5 h and 8 h. NSE expression peaked at 5 h (P < 0.05), although there was no significant difference between 5 and 8 h (P > 0.05). Bcl-2 expression gradually decreased over time in the non-induced group (P < 0.05). However, Bax, caspase-9, Cyt-c and caspase-3 expression gradually increased and peaked at 8 h (P < 0.05). Transmission electron microscopy revealed karyopyknosis, chromatin edge setting, mitochondria swelling and cavitation in cells at 5 h, and the mitochondrial membrane potential decreased over time, as demonstrated by laser scanning confocal microscopy. After a 5 h induction, cells differentiated into typical neurons and expressed Bcl-2, which inhibited apoptosis. Bax showed a strong apoptosis-promoting capacity, leading to changes in the mitochondrial membrane potential and structure, and then triggered the caspase-independent apoptotic response through the mitochondrial pathway. At the same time, Cyt-c was directly or indirectly released from the mitochondria to the cytoplasm to trigger the caspase-dependent apoptotic response through the mitochondrial pathway. Therefore, Bcl-2/Bax play an important role in regulating caspase-dependent and caspase-independent apoptosis mediated by the mitochondrial pathway during the differentiation of ADSCs into neurons.

AB - Subtropical reefs provide an important habitat for flora and fauna, and proper monitoring is required for conservation. Monitoring these exposed and submerged reefs is challenging and available resources are limited. Citizen science is increasing in momentum, as an applied research tool and in the variety of monitoring approaches adopted. This paper aims to demonstrate an ecological assessment and mapping approach that incorporates both top-down (volunteer marine scientists) and bottom-up (divers/community) engagement aspects of citizen science, applied at a subtropical reef at Point Lookout, Southeast Queensland, Australia. Marine scientists trained fifty citizen scientists in survey techniques that included mapping of habitat features, recording of substrate, fish and invertebrate composition, and quantifying impacts (e.g., occurrence of substrate damage, presence of litter). In 2014 these volunteers conducted four seasonal surveys along semi-permanent transects, at five sites, across three reefs. The project presented is a model on how citizen science can be conducted in a marine environment through collaboration of volunteer researchers, non researchers and local marine authorities. Significant differences in coral and algal cover were observed among the three sites, while fluctuations in algal cover were also observed seasonally. Differences in fish assemblages were apparent among sites and seasons, with subtropical fish groups observed more commonly in colder seasons. The least physical damage occurred in the most exposed sites (Flat Rock) within the highly protected marine park zones. The broad range of data collected through this top-down/bottom-up approach to citizen science exemplifies the projects' value and application for identifying ecosystem trends or patterns. The results of the project support natural resource and marine park management, providing a valuable contribution to existing scientific knowledge and the conservation of local reefs.

AB - Rapid detection of tumor-associated DNA such as Human Papillomavirus (HPV) has important clinical value for the early screening of tumors. By attaching oligonucleotides or cDNA onto the chip surface, DNA chip technology provides a rapid method to analyze gene expression. However, challenges remain regarding increasing probe density and improving detection time. To address these challenges, we proposed a DNA chip that was self-assembled from single stranded DNA in combination with high probe density and a rapid detection method. Over 200 probes could be attached to the surface of this 100-nm diameter DNA chip. For detection, the chips were adsorbed onto a mica surface and then incubated for ten minutes with HPV-DNA; the results were directly observable using atomic force microscopy (AFM). This bottom-up fabricated DNA nano chip combined with high probe density and direct AFM detection at the single molecule level will likely have numerous potential clinical applications for gene screening and the early diagnosis of cancer.

AB - The aim of this study was to assess whether the case volume of surgeons and hospitals affects the rates of postoperative complications and survival after liver transplantation. This population-based retrospective cohort study included 2938 recipients of liver transplantation performed between 1998 and 2012, enrolled from the Taiwan National Health Insurance Research Database. They were divided into two groups, according to the cumulative case volume of their operating surgeons and the case volume of their hospitals. The duration of intensive care unit stay and post-transplantation hospitalization, postoperative complications, and mortality were analyzed. The results showed that, in the low and high case volume surgeons groups, respectively, acute renal failure occurred at the rate of 14.11% and 5.86% (p<0.0001), and the overall mortality rates were 19.61% and 12.44% (p<0.0001). In the low and high case volume hospital groups, respectively, acute renal failure occurred in 11% and 7.11% of the recipients (p = 0.0004), and the overall mortality was 18.44% and 12.86% (p<0.0001). These findings suggest that liver transplantation recipients operated on higher case volume surgeons or in higher case volume hospitals have a lower rate of acute renal failure and mortality.

AB - Creativity is a complex, multi-faceted concept encompassing a variety of related aspects, abilities, properties and behaviours. If we wish to study creativity scientifically, then a tractable and well-articulated model of creativity is required. Such a model would be of great value to researchers investigating the nature of creativity and in particular, those concerned with the evaluation of creative practice. This paper describes a unique approach to developing a suitable model of how creative behaviour emerges that is based on the words people use to describe the concept. Using techniques from the field of statistical natural language processing, we identify a collection of fourteen key components of creativity through an analysis of a corpus of academic papers on the topic. Words are identified which appear significantly often in connection with discussions of the concept. Using a measure of lexical similarity to help cluster these words, a number of distinct themes emerge, which collectively contribute to a comprehensive and multi-perspective model of creativity. The components provide an ontology of creativity: a set of building blocks which can be used to model creative practice in a variety of domains. The components have been employed in two case studies to evaluate the creativity of computational systems and have proven useful in articulating achievements of this work and directions for further research. PMID- 27706186 TI - Drivers of Bird Species Richness within Moist High-Altitude Grasslands in Eastern South Africa. AB - Moist high-altitude grasslands in South Africa are renowned for high avifaunal diversity and are priority areas for conservation. Conservation management of these areas conflicts with management for other uses, such as intensive livestock agriculture, which requires annual burning and leads to heavy grazing. Recently the area has become target for water storage schemes and renewable electricity energy projects. There is therefore an urgent need to investigate environmental factors and habitat factors that affect bird species richness in order to optimise management of those areas set aside for conservation. A particularly good opportunity to study these issues arose at Ingula in the eastern South African high-altitude grasslands. An area that had been subject to intense grazing was bought by the national power utility that constructed a pumped storage scheme on part of the land and set aside the rest for bird conservation. Since the new management took over in 2005 the area has been mostly annually burned with relatively little grazing. The new management seeks scientific advice on how to maintain avian species richness of the study area. We collected bird occurrence and vegetation data along random transects between 2006 and 2010 to monitor the impact of the new management, and to study the effect of the habitat changes on bird species richness. To achieve these, we convert bird transect data to presence only data to investigate how bird species richness were related to key transect vegetation attributes under this new grassland management. First we used generalised linear mixed models, to examine changes in vegetation grass height and cover and between burned and unburned habitats. Secondly, we examined how total bird species richness varied across seasons and years. And finally we investigated which habitat vegetation attributes were correlated with species richness of a group of grassland depended bird species only. Transects that were burned showed a larger decrease in vegetation cover compared to transects that were not burned. Grass height increased over time. Bird species richness was highest in summer compared to other seasons and increased over time. Overall bird species richness increased over the three summer surveys but species richness of birds that prefer heavily grazed habitat showed little change over the three years. Changes in bird species richness were best explained by the model with grass height for combined species richness of grassland depended birds but also for birds that prefer heavy grazing when treated alone. On one hand birds that prefer moderate grazing were best explained by a null model. However, overall bird species richness was better positively correlated to grass height than grass cover or dead grass. We conclude that frequent burning alone with relatively reduced grazing led to higher but less dense grass, which benefited some species and disadvantaged others. We suggest that management of this grassland use combination of fire and grazing and leave some areas unburned to accommodates birds of various habitat needs.

AB - In the past decades ancient DNA research has brought numerous insights to archaeological research where traditional approaches were limited. The determination of sex in human skeletal remains is often challenging for physical anthropologists when dealing with incomplete, juvenile or pathological specimens. Molecular approaches allow sexing on the basis of sex-specific markers or by calculating the ratio of DNA derived from different chromosomes. Here we propose a novel approach that relies on the ratio of X chromosome-derived shotgun sequencing data to the autosomal coverage, thus establishing the probability of an XX or XY karyotype. Applying this approach to the individuals of the Upper Paleolithic triple burial of Dolni Vestonice reveals that all three skeletons, including the individual DV 15, whose sex has long been debated due to a pathological condition, were male. PMID- 27706189 TI - LudusScope: Accessible Interactive Smartphone Microscopy for Life-Science Education. AB - For centuries, observational microscopy has greatly facilitated biology education, but we still cannot easily and playfully interact with the microscopic world we see. We therefore developed the LudusScope, an accessible, interactive do-it-yourself smartphone microscopy platform that promotes exploratory stimulation and observation of microscopic organisms, in a design that combines the educational modalities of build, play, and inquire. The LudusScope's touchscreen and joystick allow the selection and stimulation of phototactic microorganisms such as Euglena gracilis with light. Organismal behavior is tracked and displayed in real time, enabling open and structured game play as well as scientific inquiry via quantitative experimentation. Furthermore, we used the Scratch programming language to incorporate biophysical modeling. This platform is designed as an accessible, low-cost educational kit for easy construction and expansion. User testing with both teachers and students demonstrates the educational potential of the LudusScope, and we anticipate additional synergy with the maker movement. Transforming observational microscopy into an interactive experience will make microbiology more tangible to society, and effectively support the interdisciplinary learning required by the Next Generation Science Standards.

AB - In this study, assessment of the safety of transgenic rice T1C-1 expressing Cry1C was carried out by: (1) studying horizontal gene transfer (HGT) in Sprague Dawley rats fed transgenic rice for 90 d; (2) examining the effect of Cry1C protein in vitro on digestibility and allergenicity; and (3) studying the changes of intestinal microbiota in rats fed with transgenic rice T1C-1 in acute and subchronic toxicity tests. Sprague Dawley rats were fed a diet containing either 60% GM Bacillus thuringiensis (Bt) rice T1C-1 expressing Cry1C protein, the parental rice Minghui 63, or a basic diet for 90 d. The GM Bt rice T1C-1 showed no evidence of HGT between rats and transgenic rice. Sequence searching of the Cry1C protein showed no homology with known allergens or toxins. Cry1C protein was rapidly degraded in vitro with simulated gastric and intestinal fluids. The expressed Cry1C protein did not induce high levels of specific IgG and IgE antibodies in rats. The intestinal microbiota of rats fed T1C-1 was also analyzed in acute and subchronic toxicity tests by DGGE. Cluster analysis of DGGE profiles revealed significant individual differences in the rats' intestinal microbiota. PMID- 27706191 TI - Two New Cynodonts (Therapsida) from the Middle-Early Late Triassic of Brazil and Comments on South American Probainognathians. AB - We describe two new cynodonts from the early Late Triassic of southern Brazil. One taxon, Bonacynodon schultzi gen. et sp. nov., comes from the lower Carnian Dinodontosaurus AZ, being correlated with the faunal association at the upper half of the lower member of the Chanares Formation (Ischigualasto-Villa Union Basin, Argentina). Phylogenetically, Bonacynodon is a closer relative to Probainognathus jenseni than to any other probainognathian, bearing conspicuous canines with a denticulate distal margin. The other new taxon is Santacruzgnathus abdalai gen. et sp. nov. from the Carnian Santacruzodon AZ. Although based exclusively on a partial lower jaw, it represents a probainognathian close to Prozostrodon from the Hyperodapedon AZ and to Brasilodon, Brasilitherium and Botucaraitherium from the Riograndia AZ. The two new cynodonts and the phylogenetic hypothesis presented herein indicate the degree to which our knowledge on probainognathian cynodonts is incomplete and also the relevance of the South American fossil record for understanding their evolutionary significance. The taxonomic diversity and abundance of probainognathians from Brazil and Argentina will form the basis of deep and complex studies to address the evolutionary transformations of cynodonts leading to mammals. PMID- 27706190 TI - Influence of Different Levels of Lipoic Acid Synthase Gene Expression on Diabetic Nephropathy. AB - Oxidative stress is implicated in the pathogenesis of diabetic nephropathy (DN) but outcomes of many clinical trials are controversial. To define the role of antioxidants in kidney protection during the development of diabetic nephropathy, we have generated a novel genetic antioxidant mouse model with over- or under expression of lipoic acid synthase gene (Lias). These models have been mated with Ins2Akita/+ mice, a type I diabetic mouse model. We compare the major pathologic changes and oxidative stress status in two new strains of the mice with controls. Our results show that Ins2Akita/+ mice with under-expressed Lias gene, exhibit higher oxidative stress and more severe DN features (albuminuria, glomerular basement membrane thickening and mesangial matrix expansion). In contrast, Ins2Akita/+ mice with highly-expressed Lias gene display lower oxidative stress and less DN pathologic changes. Our study demonstrates that strengthening endogenous antioxidant capacity could be an effective strategy for prevention and treatment of DN. PMID- 27706192 TI - Population-Area Relationship for Medieval European Cities. AB - Medieval European urbanization presents a line of continuity between earlier cities and modern European urban systems. Yet, many of the spatial, political and economic features of medieval European cities were particular to the Middle Ages, and subsequently changed over the Early Modern Period and Industrial Revolution. There is a long tradition of demographic studies estimating the population sizes of medieval European cities, and comparative analyses of these data have shed much light on the long-term evolution of urban systems. However, the next step-to systematically relate the population size of these cities to their spatial and socioeconomic characteristics-has seldom been taken. This raises a series of interesting questions, as both modern and ancient cities have been observed to obey area-population relationships predicted by settlement scaling theory. To address these questions, we analyze a new dataset for the settled area and population of 173 European cities from the early fourteenth century to determine the relationship between population and settled area. To interpret this data, we develop two related models that lead to differing predictions regarding the quantitative form of the population-area relationship, depending on the level of social mixing present in these cities. Our empirical estimates of model parameters show a strong densification of cities with city population size, consistent with patterns in contemporary cities. Although social life in medieval Europe was orchestrated by hierarchical institutions (e.g., guilds, church, municipal organizations), our results show no statistically significant influence of these institutions on agglomeration effects. The similarities between the empirical patterns of settlement relating area to population observed here support the hypothesis that cities throughout history share common principles of organization that self-consistently relate their socioeconomic networks to structured urban spaces. PMID- 27706193 TI - Outstanding Symptoms of Poststroke Depression during the Acute Phase of Stroke. AB - Poststroke depression (PSD) is a critical complication which might lead to unfavorable outcomes. However, most cases of PSD in the acute phase, during the 2 or 3 weeks following a stroke, are neglected because of the variable comorbid conditions. In this study, aimed at revealing the outstanding symptoms of PSD during the acute phase, consecutive patients with intracranial hemorrhage (ICH) or brain infarction (BI) were asked to fill out a depression questionnaire (Quick Inventory of Depressive Symptomatology Self-Report: QIDS-SR) at 1 week and 1 month following stroke onset. Patients with disturbed consciousness or aphasia were excluded from this study. Forty-nine ICH patients and 222 BI patients completed the QIDS-SR at 1 week and 27 of ICH and 62 of BI at 1 month. The PSD rate was 67% and 46% at 1 week in ICH and BI, respectively. Although sleep disturbance was the most frequent symptom of PSD, psychomotor agitation and appetite disturbance were the most distinguishing symptoms in ICH at 1 week and fatigue at 1 month. On the other hand, most of the depressive symptoms addressed in QIDS-SR were observed in PSD of BI patients both at 1 week and 1 month. In conclusion, while sleep disturbance was a frequent but non-specific symptom, appetite disturbance and fatigue might be critical symptoms to suggest PSD during the acute phase of stroke. PMID- 27706194 TI - Work-Related Factors Considered by Sickness-Absent Employees When Estimating Timeframes for Returning to Work. AB - INTRODUCTION: Work-related factors have been found to be influential in shaping a number of return-to-work outcomes including return-to-work expectations. Based on the idea that work-related factors have the potential for modification through workplace-based initiatives, this study involved a detailed examination of work related factors referenced by workers as being taken into consideration when estimating timeframes for returning to work. METHODS: Focus groups were conducted with 30 employees, currently off work (<= 3 months) due to a musculoskeletal condition. During the focus groups, participants wrote and spoke about the factors that they considered when forming their expectations for returning to work. Data were subjected to thematic content analysis. RESULTS: Discussions revealed that participants' considerations tended to differ depending on whether or not they had a job to return to. Those with jobs (n = 23) referenced specific influences such as working relationships, accommodations, physical and practical limitations, as well as concerns about their ability to do their job. Those without a job to return to (n = 7) talked about the ways they would go about finding work, and how long they thought this would take. Both groups mentioned the influence of wanting to find the "right" job, retraining and being limited due to the need for income. CONCLUSION: Findings indicate that employees reference numerous work-related factors when estimating their timeframes for returning to work, and that many of these have been previously identified as relating to other return-to-work outcomes. Findings suggest the potential to improve return-to-work expectation through addressing work-related influences, and helping people work through the tasks they need to complete in order to move forward in the return-to-work process. PMID- 27706195 TI - A Possible Link between Gastric Mucosal Atrophy and Gastric Cancer after Helicobacter pylori Eradication. AB - BACKGROUND: The effect of H. pylori eradication in gastric cancer prevention can be attributed to the improvement of atrophic gastritis, which is a known risk of gastric cancer. However, gastric cancer has also been diagnosed after long-term H. pylori eradication. This study aimed to clarify the association between gastric atrophy and gastric cancer after H. pylori eradication, including its clinicopathological features. METHODS: A total of 55 consecutive patients with 64 early gastric cancers (EGCs) diagnosed after H. pylori eradication were enrolled. The degree of endoscopic atrophy and the histological degrees of mononuclear cell infiltration, atrophy, and metaplasia in the corpus and adjacent mucosa of the EGCs were determined and scored. RESULTS: The majority of EGCs (63/64) were located within the endoscopically assessed atrophic mucosa or along the atrophic border. The adjacent mucosa of the EGCs presented significantly higher degrees of all histological parameters than in the corpus (mononuclear cell infiltration, 0.86+/-0.09 vs. 0.51+/-0.11, P = 0.016; atrophy, 1.77+/-0.13 vs. 0.65+/-0.14, P<0.0001; metaplasia, 1.68+/-0.13 vs. 0.48+/-0.1, P<0.0001). The degree of endoscopic atrophy improved in the patients with longer post-H. pylori eradication periods; however, this trend was not observed for the histological parameters, and high degrees of atrophy and metaplasia were observed in the adjacent mucosa of the EGCs compared with the corpus during all periods (all P<0.05). The histological degrees of atrophy and metaplasia in the adjacent mucosa were particularly higher in the patients who underwent eradication due to gastric ulcers. CONCLUSIONS: Severe gastric atrophy remained in the adjacent mucosa of the EGCs after H. pylori eradication, which may be linked to gastric carcinogenesis. PMID- 27706197 TI - Communally Nesting Migratory Birds Create Ecological Hot-Spots in Tropical Australia. AB - Large numbers of metallic starlings (Aplonis metallica) migrate annually from New Guinea to the rainforests of tropical Australia, where they nest communally in single emergent trees (up to 1,000 birds). These aggregations create dense and species-rich faunal "hot-spots", attracting a diverse assemblage of local consumers that utilise this seasonal resource. The starlings nested primarily in poison-dart trees (Antiaris toxicaria) near the rainforest-woodland boundary. Surveys underneath these colonies revealed that bird-derived nutrients massively increased densities of soil invertebrates and mammals (primarily wild pigs) beneath trees, year-round. Flying invertebrates, nocturnal birds, reptiles, and amphibians congregated beneath the trees when starlings were nesting (the wet season). Diurnal birds (primarily cockatoos and bush turkeys) aggregated beneath the trees during the dry-season to utilise residual nutrients when the starlings were not nesting. The abundance of several taxa was considerably higher (to > 1000-fold) under colony trees than under nearby trees. The system strikingly resembles utilisation of bird nesting colonies by predators in other parts of the world but this spectacular system has never been described, emphasizing the continuing need for detailed natural-history studies in tropical Australia. PMID- 27706196 TI - Reliability of a Novel High Intensity One Leg Dynamic Exercise Protocol to Measure Muscle Endurance. AB - We recently developed a high intensity one leg dynamic exercise (OLDE) protocol to measure muscle endurance and investigate the central and peripheral mechanisms of muscle fatigue. The aims of the present study were to establish the reliability of this novel protocol and describe the isokinetic muscle fatigue induced by high intensity OLDE and its recovery. Eight subjects performed the OLDE protocol (time to exhaustion test of the right leg at 85% of peak power output) three times over a week period. Isokinetic maximal voluntary contraction torque at 60 (MVC60), 100 (MVC100) and 140 (MVC140) deg/s was measured pre exercise, shortly after exhaustion (13 +/- 4 s), 20 s (P20) and 40 s (P40) post exercise. Electromyographic (EMG) signal was analyzed via the root mean square (RMS) for all three superficial knee extensors. Mean time to exhaustion was 5.96 +/- 1.40 min, coefficient of variation was 8.42 +/- 6.24%, typical error of measurement was 0.30 min and intraclass correlation was 0.795. MVC torque decreased shortly after exhaustion for all angular velocities (all P < 0.001). MVC60 and MVC100 recovered between P20 (P < 0.05) and exhaustion and then plateaued. MVC140 recovered only at P40 (P < 0.05). High intensity OLDE did not alter maximal EMG RMS of the three superficial knee extensors during MVC. The results of this study demonstrate that this novel high intensity OLDE protocol could be reliably used to measure muscle endurance, and that muscle fatigue induced by high intensity OLDE should be examined within ~ 30 s following exhaustion. PMID- 27706198 TI - The Asian Correction Can Be Quantitatively Forecasted Using a Statistical Model of Fusion-Fission Processes. AB - The Global Financial Crisis of 2007-2008 wiped out US$37 trillions across global financial markets, this value is equivalent to the combined GDPs of the United States and the European Union in 2014. The defining moment of this crisis was the failure of Lehman Brothers, which precipitated the October 2008 crash and the Asian Correction (March 2009). Had the Federal Reserve seen these crashes coming, they might have bailed out Lehman Brothers, and prevented the crashes altogether. In this paper, we show that some of these market crashes (like the Asian Correction) can be predicted, if we assume that a large number of adaptive traders employing competing trading strategies. As the number of adherents for some strategies grow, others decline in the constantly changing strategy space. When a strategy group grows into a giant component, trader actions become increasingly correlated and this is reflected in the stock price. The fragmentation of this giant component will leads to a market crash. In this paper, we also derived the mean-field market crash forecast equation based on a model of fusions and fissions in the trading strategy space. By fitting the continuous returns of 20 stocks traded in Singapore Exchange to the market crash forecast equation, we obtain crash predictions ranging from end October 2008 to mid-February 2009, with early warning four to six months prior to the crashes. PMID- 27706199 TI - An Outcome-Weighted Network Model for Characterizing Collaboration. AB - Shared patient encounters form the basis of collaborative relationships, which are crucial to the success of complex and interdisciplinary teamwork in healthcare. Quantifying the strength of these relationships using shared risk adjusted patient outcomes provides insight into interactions that occur between healthcare providers. We developed the Shared Positive Outcome Ratio (SPOR), a novel parameter that quantifies the concentration of positive outcomes between a pair of healthcare providers over a set of shared patient encounters. We constructed a collaboration network using hospital emergency department patient data from electronic health records (EHRs) over a three-year period. Based on an outcome indicating patient satisfaction, we used this network to assess pairwise collaboration and evaluate the SPOR. By comparing this network of 574 providers and 5,615 relationships to a set of networks based on randomized outcomes, we identified 295 (5.2%) pairwise collaborations having significantly higher patient satisfaction rates. Our results show extreme high- and low-scoring relationships over a set of shared patient encounters and quantify high variability in collaboration between providers. We identified 29 top performers in terms of patient satisfaction. Providers in the high-scoring group had both a greater average number of associated encounters and a higher percentage of total encounters with positive outcomes than those in the low-scoring group, implying that more experienced individuals may be able to collaborate more successfully. Our study shows that a healthcare collaboration network can be structurally evaluated to characterize the collaborative interactions that occur between healthcare providers in a hospital setting. PMID- 27706200 TI - Early Warning Signals of Social Transformation: A Case Study from the US Southwest. AB - Recent research in ecology suggests that generic indicators, referred to as early warning signals (EWS), may occur before significant transformations, both critical and non-critical, in complex systems. Up to this point, research on EWS has largely focused on simple models and controlled experiments in ecology and climate science. When humans are considered in these arenas they are invariably seen as external sources of disturbance or management. In this article we explore ways to include societal components of socio-ecological systems directly in EWS analysis. Given the growing archaeological literature on 'collapses,' or transformations, in social systems, we investigate whether any early warning signals are apparent in the archaeological records of the build-up to two contemporaneous cases of social transformation in the prehistoric US Southwest, Mesa Verde and Zuni. The social transformations in these two cases differ in scope and severity, thus allowing us to explore the contexts under which warning signals may (or may not) emerge. In both cases our results show increasing variance in settlement size before the transformation, but increasing variance in social institutions only before the critical transformation in Mesa Verde. In the Zuni case, social institutions appear to have managed the process of significant social change. We conclude that variance is of broad relevance in anticipating social change, and the capacity of social institutions to mitigate transformation is critical to consider in EWS research on socio-ecological systems. PMID- 27706201 TI - Cell Blebbing in Confined Microfluidic Environments. AB - Migrating cells can extend their leading edge by forming myosin-driven blebs and F-actin-driven pseudopods. When coerced to migrate in resistive environments, Dictyostelium cells switch from using predominately pseudopods to blebs. Bleb formation has been shown to be chemotactic and can be influenced by the direction of the chemotactic gradient. In this study, we determine the blebbing responses of developed cells of Dictyostelium discoideum to cAMP gradients of varying steepness produced in microfluidic channels with different confining heights, ranging between 1.7 MUm and 3.8 MUm. We show that microfluidic confinement height, gradient steepness, buffer osmolarity and Myosin II activity are important factors in determining whether cells migrate with blebs or with pseudopods. Dictyostelium cells were observed migrating within the confines of microfluidic gradient channels. When the cAMP gradient steepness is increased from 0.7 nM/MUm to 20 nM/MUm, cells switch from moving with a mixture of blebs and pseudopods to moving only using blebs when chemotaxing in channels with confinement heights less than 2.4 MUm. Furthermore, the size of the blebs increases with gradient steepness and correlates with increases in myosin-II localization at the cell cortex. Reduction of intracellular pressure by high osmolarity buffer or inhibition of myosin-II by blebbistatin leads to a decrease in bleb formation and bleb size. Together, our data reveal that the protrusion type formed by migrating cells can be influenced by the channel height and the steepness of the cAMP gradient, and suggests that a combination of confinement induced myosin-II localization and cAMP-regulated cortical contraction leads to increased intracellular fluid pressure and bleb formation. PMID- 27706202 TI - PubMedPortable: A Framework for Supporting the Development of Text Mining Applications. AB - Information extraction from biomedical literature is continuously growing in scope and importance. Many tools exist that perform named entity recognition, e.g. of proteins, chemical compounds, and diseases. Furthermore, several approaches deal with the extraction of relations between identified entities. The BioCreative community supports these developments with yearly open challenges, which led to a standardised XML text annotation format called BioC. PubMed provides access to the largest open biomedical literature repository, but there is no unified way of connecting its data to natural language processing tools. Therefore, an appropriate data environment is needed as a basis to combine different software solutions and to develop customised text mining applications. PubMedPortable builds a relational database and a full text index on PubMed citations. It can be applied either to the complete PubMed data set or an arbitrary subset of downloaded PubMed XML files. The software provides the infrastructure to combine stand-alone applications by exporting different data formats, e.g. BioC. The presented workflows show how to use PubMedPortable to retrieve, store, and analyse a disease-specific data set. The provided use cases are well documented in the PubMedPortable wiki. The open-source software library is small, easy to use, and scalable to the user's system requirements. It is freely available for Linux on the web at https://github.com/KerstenDoering/PubMedPortable and for other operating systems as a virtual container. The approach was tested extensively and applied successfully in several projects. PMID- 27706203 TI - Longitudinal Lung Function Decrease in Subjects with Spontaneous Healed Pulmonary Tuberculosis. AB - OBJECTIVE: We compared the longitudinal course of post-bronchodilator Forced Expiratory Volume in 1 second (pFEV1) over a 10-year period in subjects with spontaneous healed pulmonary tuberculosis (SHPTB) with that in normal subjects. METHODS: We prospectively investigated 339 subjects with SHPTB and 3211 normal subjects. pFEV1 values measured biannually over 10 years were analyzed using mixed effects model. RESULTS: At baseline, there were no differences in gender, smoking amount, and mean height, except mean age (50.0 +/- 8.1 VS. 48.1 +/- 7.3, P< 0.001) between the SHPTB and normal group. 52% of the 339 participants with SHPTB and 56% of the 3211 normal participants participated till the end of study. According to the final model, the SHPTB group showed significantly larger decrease in the average pFEV1 over the time than the normal group (P< 0.001) adjusted for gender, age, height, smoking pack years, and time effects. Especially, the interaction effect between time and group was statistically significant (P = 0.036). CONCLUSION: The average lung function in terms of pFEV1 decreases faster in subjects with SHPTB than in normal individuals over time.

AB - ATP induces pain via activation of purinergic receptors in nociceptive sensory nerves. ATP signaling is terminated by ATP hydrolysis mediated by cell surface localized ecto-nucleotidases. Using enzymatic histochemical staining, we show that ecto-ATPase activity is present in mouse trigeminal nerves. Using immunofluorescence staining, we found that ecto-NTPDase3 is expressed in trigeminal nociceptive neurons and their projections to the brainstem. In addition, ecto-ATPase activity and ecto-NTPDase3 are also detected in the nociceptive outermost layer of the trigeminal subnucleus caudalis. Furthermore, we demonstrate that incubation with anti-NTPDase3 serum reduces extracellular ATP degradation in the nociceptive lamina of both the trigeminal subnucleus caudalis and the spinal cord dorsal horn. These results are consistent with neuronal NTPDase3 activity modulating pain signal transduction and transmission by affecting extracellular ATP hydrolysis within the trigeminal nociceptive pathway. Thus, disruption of trigeminal neuronal NTPDase3 expression and localization to presynaptic terminals during chronic inflammation, local constriction and injury may contribute to the pathogenesis of orofacial neuropathic pain. PMID- 27706205 TI - Action of SNAIL1 in Cardiac Myofibroblasts Is Important for Cardiac Fibrosis following Hypoxic Injury. AB - Hypoxic injury to the heart results in cardiac fibrosis that leads to cardiac dysfunction and heart failure. SNAIL1 is a zinc finger transcription factor implicated in fibrosis following organ injury and cancer. To determine if the action of SNAIL1 contributed to cardiac fibrosis following hypoxic injury, we used an endogenous SNAIL1 bioluminescence reporter mice, and SNAIL1 knockout mouse models. Here we report that SNAIL1 expression is upregulated in the infarcted heart, especially in the myofibroblasts. Utilizing primary cardiac fibroblasts in ex vivo cultures we find that pro-fibrotic factors and collagen I increase SNAIL1 protein level. SNAIL1 is required in cardiac fibroblasts for the adoption of myofibroblast fate, collagen I expression and expression of fibrosis related genes. Taken together this data suggests that SNAIL1 expression is induced in the cardiac fibroblasts after hypoxic injury and contributes to myofibroblast phenotype and a fibrotic scar formation. Resultant collagen deposition in the scar can maintain elevated SNAIL1 expression in the myofibroblasts and help propagate fibrosis. PMID- 27706206 TI - Incidences and Risk Factors of Organ Manifestations in the Early Course of Systemic Sclerosis: A Longitudinal EUSTAR Study. AB - OBJECTIVE: Systemic sclerosis (SSc) is a rare and clinically heterogeneous autoimmune disorder characterised by fibrosis and microvascular obliteration of the skin and internal organs. Organ involvement mostly manifests after a variable period of the onset of Raynaud's phenomenon (RP). We aimed to map the incidence and predictors of pulmonary, cardiac, gastrointestinal (GI) and renal involvement in the early course of SSc. METHODS: In the EUSTAR cohort, patients with early SSc were identified as those who had a visit within the first year after RP onset. Incident SSc organ manifestations and their risk factors were assessed using Kaplan-Meier methods and Cox regression analysis. RESULTS: Of the 695 SSc patients who had a baseline visit within 1 year after RP onset, the incident non RP manifestations (in order of frequency) were: skin sclerosis (75%) GI symptoms (71%), impaired diffusing capacity for monoxide<80% predicted (65%), DU (34%), cardiac involvement (32%), FVC<80% predicted (31%), increased PAPsys>40mmHg (14%), and renal crisis (3%). In the heart, incidence rates were highest for diastolic dysfunction, followed by conduction blocks and pericardial effusion. While the main baseline risk factor for a short timespan to develop FVC impairment was diffuse skin involvement, for PAPsys>40mmHg it was higher patient age. The main risk factors for incident cardiac manifestations were anti topoisomerase autoantibody positivity and older age. Male sex, anti-RNA polymerase-III positivity, and older age were risk factors associated with incident renal crisis. CONCLUSION: In SSc patients presenting early after RP onset, approximately half of all incident organ manifestations occur within 2 years and have a simultaneous rather than a sequential onset. These findings have implications for the design of new diagnostic and therapeutic strategies aimed to 'widen' the still very narrow 'window of opportunity'. They may also enable physicians to counsel and manage patients presenting early in the course of SSc more accurately. PMID- 27706207 TI - Adiponectin Fractions Influence the Development of Posttransplant Diabetes Mellitus and Cardiovascular Disease in Japanese Renal Transplant Recipients. AB - BACKGROUND: A few studies have investigated the role of adiponectin fraction for cardiovascular disease (CVD) in RTx recipients. SUBJECTS AND METHODS: We studied 57 adult subjects (39 males, 18 females; 10 cadaveric donors) with at least three years of allograft survival (median 251 months). We examined clinical backgrounds such as treated drugs, blood pressure (BP, mmHg), body mass index (BMI), and blood chemistry including cholesterol (total, LDL-C, HDL-C), glucose, glycated hemoglobin (HbA1c), and serum high and low-molecular-weight (HMW/LMW) ADPN fractions with regard to the associations of the visceral and subcutaneous fat areas on CT scan. We also analyzed the associations of CVD and post-transplant diabetes (PTDM) with ADPN fractions and the fat areas. RESULTS: The visceral fat area was inversely correlated with serum HMW and LMW ADPN levels and HMW ADPN ratio (r = -0.400, p = 0.002 and r = -0.296, p = 0.025 and r = -0.444, p<0.001, respectively). Furthermore, the visceral fat area was positively with the LMW ADPN ratio (r = 0.467, p<0.001), but no significant correlation was noted between the subcutaneous fat area and the ADPN ratio. On multiple regression analysis, eGFR and the visceral fat area were significant reducing factors of HMW ADPN levels, and the alteration of eGFR was identified as an increasing factor of HMW ADPN levels. Patients with CVD had larger visceral fat area (p = 0.004), lower HMW ADPN ratio (p = 0.022) and higher LMW ADPN ratio (p = 0.049). In addition, the higher HMW ADPN ratio and statin treatment were identified as reducing factors of the development of CVD, but the LDL-C level was an aggravating factor. Moreover, the higher LMW ADPN ratio and the visceral fat area were aggravating factors of PTDM. CONCLUSION: Even in Japanese renal transplant recipients, visceral fat area and ADPN fractions were significant factors for the development of both CVD and PTDM. PMID- 27706208 TI - Influence of the Infrapatellar Fat Pad Resection during Total Knee Arthroplasty: A Systematic Review and Meta-Analysis. AB - BACKGROUND: To enhance surgical exposure, resection of the infrapatellar fat pad (IPFP) is usually a routine procedure in total knee arthroplasty (TKA). However, there is conflicting evidence regarding whether IPFP resection during TKA impairs clinical outcome. We performed a systematic review and meta-analysis to clarify the influence of IPFP resection on primary TKA. METHODS: Embase, PubMed, and the Cochrane Library were systematically searched up to August 2016 to identify relevant studies. All clinical studies comparing IPFP resection (IPFP-R) and IPFP preservation (IPFP-P) in patients undergoing primary TKA were obtained. The meta analysis was performed with Revman 5.3 and STATA 12.0 software. The weighted mean was estimated by using random effects (RE) models with 95% CIs, heterogeneity was assessed using the H statistic and the inconsistency index (I2). RESULTS: Seven studies involving 2,734 patients (3,258 knees) were included. IPFP resection trended to increase the incidence of postoperative anterior knee pain within 2 months postoperatively, compared with patients in whom the IPFP was preserved (odds ratio [OR]s 2.12[0.95, 4.73], p = 0.07). An increased incidence of anterior knee pain was observed in the IPFP resection group > 12 months postoperatively, but the difference was not significant (OR, 3.69 [0.81, 16.82], p = 0.07). In addition, a trend towards more shortening of the patellar tendon was also observed in the IPFP-R group. No significant results were found regarding postoperative knee function. CONCLUSION: These results suggest that preserving the IPFP may be superior to IPFP resection in patients undergoing primary TKA, due to the relatively lower rate of anterior knee pain after short-term follow up. PMID- 27706209 TI - Adipose-Derived Stem Cells Respond to Increased Osmolarities. AB - Cell therapies present a feasible option for the treatment of degenerated cartilaginous and intervertebral disc (IVD) tissues. Microenvironments of these tissues are specific and often differ from the microenvironment of cells that, could be potentially used for therapy, e.g. human adipose-derived stem cells (hASC). To ensure safe and efficient implantation of hASC, it is important to evaluate how microenvironmental conditions at the site of implantation affect the implanted cells. This study has demonstrated that cartilaginous tissue-specific osmolarities ranging from 400-600 mOsm/L affected hASC in a dose- and time dependent fashion in comparison to 300 mOsm/L. Increased osmolarities resulted in transient (nuclear DNA and actin reorganisation) and non-transient, long-term morphological changes (vesicle formation, increase in cell area, and culture morphology), as well as reduced proliferation in monolayer cultures. Increased osmolarities diminished acid proteoglycan production and compactness of chondrogenically induced pellet cultures, indicating decreased chondrogenic potential. Viability of hASC was strongly dependent on the type of culture, with hASC in monolayer culture being more tolerant to increased osmolarity compared to hASC in suspension, alginate-agarose hydrogel, and pellet cultures, thus emphasizing the importance of choosing relevant in vitro conditions according to the specifics of clinical application. PMID- 27706210 TI - Molecular Typing of Legionella pneumophila Isolates in the Province of Quebec from 2005 to 2015. AB - Legionella is found in natural and man-made aquatic environments, such as cooling towers and hot water plumbing infrastructures. Legionella pneumophila serogroup 1 (Lp1) is the most common etiological agent causing waterborne disease in the United States and Canada. This study reports the molecular characterization of Lp strains during a 10 year period. We conducted sequence-based typing (SBT) analysis on a large set of Lp isolates (n = 284) to investigate the province of Quebec sequence types (STs) distribution in order to identify dominant clusters. From 2005 to 2015, 181 clinical Lp isolates were typed by SBT (141 sporadic cases and 40 outbreak related cases). From the same period of time, 103 environmental isolates were also typed. Amongst the 108 sporadic cases of Lp1 typed, ST-62 was the most frequent (16.6%), followed by ST-213 (10.2%), ST-1 (8.3%) and ST-37 (8.3%). Amongst other serogroups (SG), ST-1327 (SG5) (27.3%) and ST-378 (SG10) (12.2%) were the most frequent. From the environmental isolates, ST-1 represent the more frequent SBT type (26.5%). Unweighted pair group method with arithmetic mean (UPGMA) dendrogram from the 108 sporadic cases of SG1 contains 4 major clusters (A to D) of related STs. Cluster B contains the majority of the strains (n = 61) and the three most frequent STs in our database (ST-62, ST-213 and ST 1). During the study period, we observed an important increase in the incidence rate in Quebec. All the community associated outbreaks, potentially or confirmed to be associated with a cooling tower were caused by Lp1 strains, by opposition to hospital associated outbreaks that were caused by serogroups of Lp other than SG1. The recent major Quebec City outbreak caused by ST-62, and the fact that this genotype is the most common in the province supports whole genome sequencing characterization of this particular sequence type in order to understand its evolution and associated virulence factors. PMID- 27706211 TI - Altered Immune Cytokine Expression Associated with KoRV B Infection and Season in Captive Koalas. AB - Koala (Phascolarctos cinereus) populations are increasingly vulnerable and one of the main threats is chlamydial infection. Koala retrovirus (KoRV) has been proposed as an underlying cause of the koala's susceptibility to infection with Chlamydia and high rates of lymphoid neoplasia; however, the regionally ubiquitous, endogenous nature of this virus suggests that KoRV A infection is not sufficient for immune suppression to occur. A recently discovered exogenous variant of KoRV, KoRV B, has several structural elements that cause increased pathogenicity in related retroviruses and was associated with lymphoid neoplasia in one study. The present study assesses whether KoRV B infection is associated with alterations in immune function. Cytokine gene expression by mitogen stimulated lymphocytes of KoRV B positive (n = 5-6) and negative (n = 6-7) captive koalas was evaluated by qPCR four times (April 2014-February 2015) to control for seasonal variation. Key immune genes in the Th1 pathway (IFNgamma, TNFalpha), Th2 pathway (IL 10, IL4, IL6) and Th17 pathway (IL17A), along with CD4:CD8 ratio, were assessed. KoRV B positive koalas showed significantly increased up-regulation of IL17A and IL10 in three out of four sampling periods and IFNgamma, IL6, IL4 and TNFalpha in two out of four. IL17A is an immune marker for chlamydial pathogenesis in the koala; increased expression of IL17A in KoRV B positive koalas, and concurrent immune dysregulation, may explain the differences in susceptibility to chlamydial infection and severity of disease seen between individuals and populations. There was also marked seasonal variation in up regulation for most of the cytokines and the CD4:CD8 ratio. The up-regulation in both Th1 and Th2 cytokines mirrors changes associated with immune dysregulation in humans and felids as a result of retroviral infections. This is the first report of altered immune expression in koalas infected by an exogenous variant of KoRV and also the first report of seasonal variation in cytokine up-regulation and CD4:CD8 ratio in marsupials. PMID- 27706213 TI - SeqKit: A Cross-Platform and Ultrafast Toolkit for FASTA/Q File Manipulation. AB - FASTA and FASTQ are basic and ubiquitous formats for storing nucleotide and protein sequences. Common manipulations of FASTA/Q file include converting, searching, filtering, deduplication, splitting, shuffling, and sampling. Existing tools only implement some of these manipulations, and not particularly efficiently, and some are only available for certain operating systems. Furthermore, the complicated installation process of required packages and running environments can render these programs less user friendly. This paper describes a cross-platform ultrafast comprehensive toolkit for FASTA/Q processing. SeqKit provides executable binary files for all major operating systems, including Windows, Linux, and Mac OSX, and can be directly used without any dependencies or pre-configurations. SeqKit demonstrates competitive performance in execution time and memory usage compared to similar tools. The efficiency and usability of SeqKit enable researchers to rapidly accomplish common FASTA/Q file manipulations. SeqKit is open source and available on Github at https://github.com/shenwei356/seqkit. PMID- 27706212 TI - The yapA Encodes bZIP Transcription Factor Involved in Stress Tolerance in Pathogenic Fungus Talaromyces marneffei. AB - Talaromyces marneffei, formerly Penicillium marneffei, is a thermally dimorphic fungus. It causes a fatal disseminated disease in patients infected with the human immunodeficiency virus (HIV). Studies on the stress defense mechanism of T. marneffei can lead to a better understanding of the pathogenicity and the progression of the disease due to this fungus. The basic leucine-zipper (bZip) transcription factor gene in Saccharomyces cerevisiae, named yap1 (yeast activating protein-1), is known as a crucial central regulator of stress responses including those caused by oxidative agents, cadmium, and drugs. An ortholog of yap1, designated yapA, was identified in T. marneffei. We found that the yapA gene was involved in growth and fungal cell development. The yapA deletion mutant exhibited delays in the rate of growth, germination, and conidiation. Surprisingly, the yapA gene was also involved in the pigmentation of T. marneffei. Moreover, the mutant was sensitive to oxidative stressors such as H2O2 and menadione, similar to S. cerevisiae yap1 mutant, as well as the nitrosative stressor NaNO2. In addition, the yapA mutant demonstrated significantly decreased survival in human macrophage THP-1 compared to wild-type and complemented strains. This study reveals the role of yapA in fungal growth, cell development, stress response, and potential virulence in T. marneffei. PMID- 27706214 TI - Regulation of the Flavonoid Biosynthesis Pathway Genes in Purple and Black Grains of Hordeum vulgare. AB - Barley grain at maturity can have yellow, purple, blue, and black pigmentations which are suggested to play a protective role under stress conditions. The first three types of the colors are caused by phenolic compounds flavonoids; the last one is caused by phytomelanins, oxidized and polymerized phenolic compounds. Although the genetic basis of the flavonoid biosynthesis pathway in barley has been thoroughly studied, there is no data yet on its regulation in purple and black barley grains. In the current study, genetic model of Hordeum vulgare 'Bowman' near-isogenic lines (NILs) was used to investigate the regulation of the flavonoid biosynthesis in white, purple, and black barley grains. Microsatellite genotyping revealed donor segments in the purple- and black-grained lines on chromosomes 2H (in region of the Ant2 gene determining purple color of grains) and 1H (in region of the Blp gene determining black lemma and pericarp), respectively. The isolated dominant Ant2 allele of the purple-grained line has high level of sequence similarity with the recessive Bowman's ant2 in coding region, whereas an insertion of 179 bp was detected in promoter region of ant2. This structural divergence between Ant2 and ant2 alleles may underlie their different expression in grain pericarp: Bowman's Ant2 is not transcribed, whereas it was up-regulated in the purple-grained line with coordinately co-expressed flavonoid biosynthesis structural genes (Chs, Chi, F3h, F3'h, Dfr, Ans). This led to total anthocyain content increase in purple-grained line identified by ultra performance liquid chromatography (HPLC). Collectively, these results proved the regulatory function of the Ant2 gene in anthocyanin biosynthesis in barley grain pericarp. In the black-grained line, the specific transcriptional regulation of the flavonoid biosynthesis pathway genes was not detected, suggesting that flavonoid pigments are not involved in development of black lemma and pericarp trait. PMID- 27706215 TI - Alterations of Myelin Content in Parkinson's Disease: A Cross-Sectional Neuroimaging Study. AB - Alterations to myelin may be a core pathological feature of neurodegenerative diseases. Although white matter microstructural differences have been described in Parkinson's disease (PD), it is unknown whether such differences include alterations of the brain's myelin content. Thus, the objective of the current study is to measure and compare brain myelin content between PD patients and age matched controls. In this cross-sectional study, 63 participants from the Longitudinal MRI in Parkinson's Disease study underwent brain MRI, Unified Parkinson's Disease Rating Scale (UPDRS) scoring, and cognitive asessments. Subjects were imaged with the mcDEPSOT (multi-component driven equilibrium single pulse observation of T1 and T2), a multicomponent relaxometry technique that quantifies longitudinal and transverse relaxation rates (R1 and R2, respectively) and the myelin water fraction (VFM), a surrogate for myelin content. A voxel-wise approach was used to compare R1, R2, and VFM measures between PD and control groups, and to evaluate relationships with age as well as disease duration, UPDRS scores, and daily levodopa equivalent dose. PD subjects had higher VFM than controls in frontal and temporal white matter and bilateral thalamus. Greater age was strongly associated with lower VFM in both groups, while an age-by-group interaction suggested a slower rate of VFM decline in the left putamen with aging in PD. Within the PD group, measures of disease severity, including UPDRS, daily levodopa equivalent dose, and disease duration, were observed to be related with myelin content in diffuse brain regions. The age-by-group interaction suggests that either PD or dopaminergic therapies allay observed age-related myelin changes. The relationships between VFM and disease severity measures suggests that VFM may provide a surrogate marker for microstructural changes related to Parkinson's disease. PMID- 27706217 TI - Application of 2,4-Dinitrophenylhydrazine (DNPH) in High-Throughput Screening for Microorganism Mutants Accumulating 9alpha-Hydroxyandrost-4-ene-3,17-dione (9alpha OH-AD). AB - To develop a quick method for the preliminarily screening of mutant strains that can accumulate 9alpha-hydroxyandrost-4-ene-3,17-dione (9alpha-OH-AD), a high throughput screening method was presented by applying the principle that 2,4 dinitrophenylhydrazine (DNPH) can react with ketones to produce precipitation. The optimal color assay conditions were the substrate androst-4-ene-3,17-dione (AD) concentration at 2.0 g/L, the ratio of AD to DNPH solution at 1:4, and the sulfuric acid and ethanol solution percentages in DNPH solution at 2% and 35%, respectively. This method was used to preliminarily screen the mutants of Rhodococcus rhodochrous DSM43269, from which the three ones obtained could produce more 9alpha-OH-AD. This DNPH color assay method not only broadens screening methods and increases screening efficiency in microbial mutation breeding but also establishes a good foundation for obtaining strains for industrial application. PMID- 27706216 TI - Clinical and Economic Impact of a Digital, Remotely-Delivered Intensive Behavioral Counseling Program on Medicare Beneficiaries at Risk for Diabetes and Cardiovascular Disease. AB - BACKGROUND: Type 2 diabetes and cardiovascular disease impose substantial clinical and economic burdens for seniors (age 65 and above) and the Medicare program. Intensive Behavioral Counseling (IBC) interventions like the National Diabetes Prevention Program (NDPP), have demonstrated effectiveness in reducing excess body weight and lowering or delaying morbidity onset. This paper estimated the potential health implications and medical savings of a digital version of IBC modeled after the NDPP. METHODS AND FINDINGS: Participants in this digital IBC intervention, the Omada program, include 1,121 overweight or obese seniors with additional risk factors for diabetes or heart disease. Weight changes were objectively measured via participant use of a networked weight scale. Participants averaged 6.8% reduction in body weight within 26 weeks, and 89% of participants completed 9 or more of the 16 core phase lessons. We used a Markov based microsimulation model to simulate the impact of weight loss on future health states and medical expenditures over 10 years. Cumulative per capita medical expenditure savings over 3, 5 and 10 years ranged from $1,720 to 1,770 (3 years), $3,840 to $4,240 (5 years) and $11,550 to $14,200 (10 years). The range reflects assumptions of weight re-gain similar to that seen in the DPP clinical trial (lower bound) or minimal weight re-gain aligned with age-adjusted national averages (upper bound). The estimated net economic benefit after IBC costs is $10,250 to $12,840 cumulative over 10 years. Simulation outcomes suggest reduced incidence of diabetes by 27-41% for participants with prediabetes, and stroke by approximately 15% over 5 years. CONCLUSIONS: A digital, remotely-delivered IBC program can help seniors at risk for diabetes and cardiovascular disease achieve significant weight loss, reduces risk for diabetes and cardiovascular disease, and achieve meaningful medical cost savings. These findings affirm recommendations for IBC coverage by the U.S. Preventive Services Task Force. PMID- 27706218 TI - Mapping Long-Term Functional Changes in Cerebral Blood Flow by Arterial Spin Labeling. AB - Although arterial spin labeling (ASL) is appealing for mapping long-term changes in functional activity, inter-sessional variations in basal blood flow, arterial transit times (ATTs), and alignment errors, can result in significant false activation when comparing images from separate sessions. By taking steps to reduce these sources of noise, this study assessed the ability of ASL to detect functional CBF changes between sessions. ASL data were collected in three sessions to image ATT, resting CBF and CBF changes associated with motor activation (7 participants). Activation maps were generated using rest and task images acquired in the same session and from sessions separated by up to a month. Good agreement was found when comparing between-session activation maps to within session activation maps with only a 16% decrease in precision (within-session: 90 +/- 7%) and a 13% decrease in the Dice similarity (within-session: 0.75 +/- 0.07) coefficient after a month. In addition, voxel-wise reproducibility (within session: 4.7 +/- 4.5%) and reliability (within-session: 0.89 +/- 0.20) of resting grey-matter CBF decreased by less than 18% for the between-session analysis relative to within-session values. ATT variability between sessions (5.0 +/- 2.7%) was roughly half the between-subject variability, indicating that its effects on longitudinal CBF were minimal. These results demonstrate that conducting voxel-wise analysis on CBF images acquired on different days is feasible with only modest loss in precision, highlighting the potential of ASL for longitudinal studies. PMID- 27706219 TI - Identification of Unanticipated and Novel N-Acyl L-Homoserine Lactones (AHLs) Using a Sensitive Non-Targeted LC-MS/MS Method. AB - N-acyl L-homoserine lactones (AHLs) constitute a predominant class of quorum sensing signaling molecules used by Gram-negative bacteria. Here, we report a sensitive and non-targeted HPLC-MS/MS method based on parallel reaction monitoring (PRM) to identify and quantitate known, unanticipated, and novel AHLs in microbial samples. Using a hybrid quadrupole-high resolution mass analyzer, this method integrates MS scans and all-ion fragmentation MS/MS scans to allow simultaneous detection of AHL parent-ion masses and generation of full mass spectra at high resolution and high mass accuracy in a single chromatographic run. We applied this method to screen for AHL production in a variety of Gram negative bacteria (i.e. B. cepacia, E. tarda, E. carotovora, E. herbicola, P. stewartii, P. aeruginosa, P. aureofaciens, and R. sphaeroides) and discovered that nearly all of them produce a larger set of AHLs than previously reported. Furthermore, we identified production of an uncommon AHL (i.e. 3-oxo-C7-HL) in E. carotovora and P. stewartii, whose production has only been previously observed within the genera Serratia and Yersinia. Finally, we used our method to quantitate AHL degradation in B. cepacia, E. carotovora, E. herbicola, P. stewartii, P. aeruginosa, P. aureofaciens, the non-AHL producer E. coli, and the Gram-positive bacterium B. subtilis. We found that AHL degradation ability varies widely across these microbes, of which B. subtilis and E. carotovora are the best degraders, and observed that there is a general trend for AHLs containing long acyl chains (>=10 carbons) to be degraded at faster rates than AHLs with short acyl chains (<=6 carbons). PMID- 27706220 TI - Anthropometric Study of Three-Dimensional Facial Morphology in Malay Adults. AB - OBJECTIVES: To establish the three-dimensional (3D) facial soft tissue morphology of adult Malaysian subjects of the Malay ethnic group; and to determine the morphological differences between the genders, using a non-invasive stereo photogrammetry 3D camera. MATERIAL AND METHODS: One hundred and nine subjects participated in this research, 54 Malay men and 55 Malay women, aged 20-30 years old with healthy BMI and with no adverse skeletal deviation. Twenty-three facial landmarks were identified on 3D facial images captured using a VECTRA M5-360 Head System (Canfield Scientific Inc, USA). Two angular, 3 ratio and 17 linear measurements were identified using Canfield Mirror imaging software. Intra- and inter-examiner reliability tests were carried out using 10 randomly selected images, analyzed using the intra-class correlation coefficient (ICC). Multivariate analysis of variance (MANOVA) was carried out to investigate morphologic differences between genders. RESULTS: ICC scores were generally good for both intra-examiner (range 0.827-0.987) and inter-examiner reliability (range 0.700-0.983) tests. Generally, all facial measurements were larger in men than women, except the facial profile angle which was larger in women. Clinically significant gender dimorphisms existed in biocular width, nose height, nasal bridge length, face height and lower face height values (mean difference > 3mm). Clinical significance was set at 3mm. CONCLUSION: Facial soft tissue morphological values can be gathered efficiently and measured effectively from images captured by a non-invasive stereo-photogrammetry 3D camera. Adult men in Malaysia when compared to women had a wider distance between the eyes, a longer and more prominent nose and a longer face. PMID- 27706221 TI - Modeled Dietary Impact of Pizza Reformulations in US Children and Adolescents. AB - BACKGROUND AND OBJECTIVE: Approximately 20% of US children and adolescents consume pizza on any given day; and pizza intake is associated with higher intakes of energy, sodium, and saturated fat. The reformulation of pizza products has yet to be evaluated as a viable option to improve diets of the US youth. This study modeled the effect on nutrient intakes of two potential pizza reformulation strategies based on the standards established by the Nestle Nutritional Profiling System (NNPS). METHODS: Dietary intakes were retrieved from the first 24hr-recall of the National Health and Nutrition Examination Survey (NHANES) 2011-12, for 2655 participants aged 4-19 years. The composition of pizzas in the NHANES food database (n = 69) were compared against the NNPS standards for energy, total fat, saturated fat, sodium, added sugars, and protein. In a reformulation scenario, the nutrient content of pizzas was adjusted to the NNPS standards if these were not met. In a substitution scenario, pizzas that did not meet the standards were replaced by the closest pizza, based on nutrient content, that met all of the NNPS standards. RESULTS: Pizzas consistent with all the NNPS standards (29% of all pizzas) were significantly lower in energy, saturated fat and sodium than pizzas that were not. Among pizza consumers, modeled intakes in the reformulation and substitution scenarios were lower in energy (-14 and -45kcal, respectively), saturated fat (-1.2 and -2.7g), and sodium (-143 and -153mg) compared to baseline. CONCLUSIONS: Potential industry wide reformulation of a single food category or intra-category food substitutions may positively impact dietary intakes of US children and adolescents. Further promotion and support of these complimentary strategies may facilitate the adoption and implementation of reformulation standards. PMID- 27706222 TI - Association of Overweight with Food Portion Size among Adults of Sao Paulo - Brazil. AB - BACKGROUND: Although studies show that portion size affects energy intake, few have demonstrated a link between portion size and weight status, especially in free-living populations. The objective of the present study was to assess the relationship between food portion sizes and overweight in a representative population of adults of Sao Paulo, Brazil. METHODS: Cross-sectional population based study with 1005 adults from Sao Paulo, Brazil. Dietary data were obtained from two 24-hour recalls. Reported foods were classified into groups and energy contribution, prevalence of consumers and portion sizes were calculated. Individuals were classified according to BMI in with and without overweight. Logistic regression models were used to evaluate the association between food portion sizes and being overweight. RESULTS: The most consumed food groups were: beans, breads/rolls, coffee/tea, milk, rice, and sugar. Rice, red meat, breads/rolls, and white meat were the groups with the highest percentage of contribution to total energy intake. Butter/margarine, toasts/biscuits, sugar, and cakes were the groups with the highest energy density. After adjustment for confounding variables, overweight was associated with larger portions of pizza (OR = 1.052; p = 0.048), red meat (OR = 1.025; p = 0.043), rice (OR = 1.033; p<0.001), salted snacks (OR = 1.078; p = 0.022), and soft drinks (OR = 1.016; p = 0.007). CONCLUSIONS: Larger portions of few food groups with different energy densities were associated with being overweight, suggesting that overweight may be related to the consumption of larger portion sizes of a series of food groups, not a food group alone. Additionally, we highlight the importance of considering underreporting as a confounding factor in these associations. PMID- 27706223 TI - Comparative Proteomics Reveals Strain-Specific beta-TrCP Degradation via Rotavirus NSP1 Hijacking a Host Cullin-3-Rbx1 Complex. AB - Rotaviruses (RVs) are the leading cause of severe gastroenteritis in young children, accounting for half a million deaths annually worldwide. RV encodes non structural protein 1 (NSP1), a well-characterized interferon (IFN) antagonist, which facilitates virus replication by mediating the degradation of host antiviral factors including IRF3 and beta-TrCP. Here, we utilized six human and animal RV NSP1s as baits and performed tandem-affinity purification coupled with high-resolution mass spectrometry to comprehensively characterize NSP1-host protein interaction network. Multiple Cullin-RING ubiquitin ligase (CRL) complexes were identified. Importantly, inhibition of cullin-3 (Cul3) or RING-box protein 1 (Rbx1), by siRNA silencing or chemical perturbation, significantly impairs strain-specific NSP1-mediated beta-TrCP degradation. Mechanistically, we demonstrate that NSP1 localizes to the Golgi with the host Cul3-Rbx1 CRL complex, which targets beta-TrCP and NSP1 for co-destruction at the proteasome. Our study uncovers a novel mechanism that RV employs to promote beta-TrCP turnover and provides molecular insights into virus-mediated innate immunity inhibition.

AB - BACKGROUND: Multiple novel oral anticoagulants and left atrial appendage closure devices (WATCHMAN) have been tested against dose-adjusted vitamin K antagonists in randomized controlled trials for stroke prophylaxis in non-valvular atrial fibrillation. No direct comparisons of these strategies are available from randomized controlled trials. We conducted the current analyses by combining efficacy and safety characteristics of all FDA approved stroke prophylaxis treatment strategies for patients with non-valvular atrial fibrillation. MATERIALS AND METHODS: We searched SCOPUS from 1945 till October 2015 for randomized controlled trials comparing these strategies and reporting efficacy and safety outcomes. Six randomized controlled trials were identified and included in the final analyses and review. We followed PRISMA guidelines for network meta-analyses while reporting the current analyses. We collected data on ischemic stroke, major bleeding, and the composite primary safety endpoint as defined by various randomized controlled trials. Network meta-analyses were conducted using consistency and inconsistency models for efficacy and safety outcomes. Surface under the cumulative ranking curve were then utilized to cluster rank these treatments for safety and efficacy. RESULTS: Six randomized controlled trials with 59,627 patients comparing six treatment strategies were eligible for the analyses. All prophylaxis strategies had comparable rates of ischemic stroke. Apixaban was associated with the least number of primary safety endpoint events as compared with all other treatments. In the cluster analyses assessing safety and efficacy, apixaban, edoxaban and dabigatran ranked best followed by vitamin K antagonists and rivaroxaban, whereas the WATCHMAN left atrial appendage closure device ranked last. CONCLUSIONS: Dose-adjusted vitamin K antagonists, novel oral anticoagulants, and the WATCHMAN left atrial appendage closure devices are equally efficacious for ischemic stroke prevention but these treatments have different safety profiles. More randomized controlled trials are needed to directly compare these strategies. PMID- 27706225 TI - Examination of the Position Accuracy of Implant Abutments Reproduced by Intra Oral Optical Impression. AB - An impression technique called optical impression using intraoral scanner has attracted attention in digital dentistry. This study aimed to evaluate the accuracy of the optical impression, comparing a virtual model reproduced by an intraoral scanner to a working cast made by conventional silicone impression technique. Two implants were placed on a master model. Working casts made of plaster were fabricated from the master model by silicone impression. The distance between the ball abutments and the angulation between the healing abutments of 5 mm and 7 mm height at master model were measured using Computer Numerical Control Coordinate Measuring Machine (CNCCMM) as control. Working casts were then measured using CNCCMM, and virtual models via stereo lithography data of master model were measured by a three-dimensional analyzing software. The distance between ball abutments of the master model was 9634.9 +/- 1.2 MUm. The mean values of trueness of the Lava COS and working casts were 64.5 MUm and 22.5 MUm, respectively, greater than that of control. The mean of precision values of the Lava COS and working casts were 15.6 MUm and 13.5 MUm, respectively. In the case of a 5-mm-height healing abutment, mean angulation error of the Lava COS was greater than that of the working cast, resulting in significant differences in trueness and precision. However, in the case of a 7-mm-height abutment, mean angulation errors of the Lava COS and the working cast were not significantly different in trueness and precision. Therefore, distance errors of the optical impression were slightly greater than those of conventional impression. Moreover, the trueness and precision of angulation error could be improved in the optical impression using longer healing abutments. In the near future, the development of information technology could enable improvement in the accuracy of the optical impression with intraoral scanners. PMID- 27706228 TI - Examination of Surface Deposits on Oldbury Reactor Core Graphite to Determine the Concentration and Distribution of 14C. AB - Pile Grade A graphite was used as a moderator and reflector material in the first generation of UK Magnox nuclear power reactors. As all of these reactors are now shut down there is a need to examine the concentration and distribution of long lived radioisotopes, such as 14C, to aid in understanding their behaviour in a geological disposal facility. A selection of irradiated graphite samples from Oldbury reactor one were examined where it was observed that Raman spectroscopy can distinguish between underlying graphite and a surface deposit found on exposed channel wall surfaces. The concentration of 14C in this deposit was examined by sequentially oxidising the graphite samples in air at low temperatures (450 degrees C and 600 degrees C) to remove the deposit and then the underlying graphite. The gases produced were captured in a series of bubbler solutions that were analysed using liquid scintillation counting. It was observed that the surface deposit was relatively enriched with 14C, with samples originating lower in the reactor exhibiting a higher concentration of 14C. Oxidation at 600 degrees C showed that the remaining graphite material consisted of two fractions of 14C, a surface associated fraction and a graphite lattice associated fraction. The results presented correlate well with previous studies on irradiated graphite that suggest there are up to three fractions of 14C; a readily releasable fraction (corresponding to that removed by oxidation at 450 degrees C in this study), a slowly releasable fraction (removed early at 600 degrees C in this study), and an unreleasable fraction (removed later at 600 degrees C in this study). PMID- 27706226 TI - Fourth-Generation Progestins Inhibit 3beta-Hydroxysteroid Dehydrogenase Type 2 and Modulate the Biosynthesis of Endogenous Steroids. AB - Progestins used in contraception and hormone replacement therapy are synthetic compounds designed to mimic the actions of the natural hormone progesterone and are classed into four consecutive generations. The biological actions of progestins are primarily determined by their interactions with steroid receptors, and factors such as metabolism, pharmacokinetics, bioavailability and the regulation of endogenous steroid hormone biosynthesis are often overlooked. Although some studies have investigated the effects of select progestins on a few steroidogenic enzymes, studies comparing the effects of progestins from different generations are lacking. This study therefore explored the putative modulatory effects of progestins on de novo steroid synthesis in the adrenal by comparing the effects of select progestins from the respective generations, on endogenous steroid hormone production by the H295R human adrenocortical carcinoma cell line. Ultra-performance liquid chromatography/tandem mass spectrometry analysis showed that the fourth-generation progestins, nestorone (NES), nomegestrol acetate (NoMAC) and drospirenone (DRSP), unlike the progestins selected from the first three generations, modulate the biosynthesis of several endogenous steroids. Subsequent assays performed in COS-1 cells expressing human 3betaHSD2, suggest that these progestins modulate the biosynthesis of steroid hormones by inhibiting the activity of 3betaHSD2. The Ki values determined for the inhibition of human 3betaHSD2 by NES (9.5 +/- 0.96 nM), NoMAC (29 +/- 7.1 nM) and DRSP (232 +/- 38 nM) were within the reported concentration ranges for the contraceptive use of these progestins in vivo. Taken together, our results suggest that newer, fourth generation progestins may exert both positive and negative physiological effects via the modulation of endogenous steroid hormone biosynthesis. PMID- 27706227 TI - Thermal Preference Ranges Correlate with Stable Signals of Universal Stress Markers in Lake Baikal Endemic and Holarctic Amphipods. AB - Temperature is the most pervasive abiotic environmental factor for aquatic organisms. Fluctuations in temperature range lead to changes in metabolic performance. Here, we aimed to identify whether surpassing the thermal preference zones is correlated with shifts in universal cellular stress markers of protein integrity, responses to oxidative stress and lactate content, as indicators of anaerobic metabolism. Exposure of the Lake Baikal endemic amphipod species Eulimnogammarus verrucosus (Gerstfeldt, 1858), Ommatogammarus flavus (Dybowski, 1874) and of the Holarctic amphipod Gammarus lacustris Sars 1863 (Amphipoda, Crustacea) to increasing temperatures resulted in elevated heat shock protein 70 (Hsp70) and lactate content, elevated antioxidant enzyme activities (i.e., catalase and peroxidase), and reduced lactate dehydrogenase and glutathione S transferase activities. Thus, the zone of stability (absence of any significant changes) of the studied molecular and biochemical markers correlated with the behaviorally preferred temperatures. We conclude that the thermal behavioral responses of the studied amphipods are directly related to metabolic processes at the cellular level. Thus, the determined thermal ranges may possibly correspond to the thermal optima. This relationship between species-specific behavioral reactions and stress response metabolism may have significant ecological consequences that result in a thermal zone-specific distribution (i.e., depths, feed spectrum, etc.) of species. As a consequence, by separating species with different temperature preferences, interspecific competition is reduced, which, in turn, increases a species' Darwinian fitness in its environment. PMID- 27706229 TI - Management-Related Traffic as a Stressor Eliciting Parental Care in a Roadside Nesting Bird: The European Bee-Eater Merops apiaster. AB - Traffic is often acknowledged as a threat to biodiversity, but its effects have been mostly studied on roads subjected to high traffic intensity. The impact of lower traffic intensity such as those affecting protected areas is generally neglected, but conservation-oriented activities entailing motorized traffic could paradoxically transform suitable habitats into ecological traps. Here we questioned whether roadside-nesting bee-eaters Merops apiaster perceived low traffic intensity as a stressor eliciting risk-avoidance behaviors (alarm calls and flock flushes) and reducing parental care. Comparisons were established within Donana National Park (Spain), between birds exposed to either negligible traffic (ca. 0-10 vehicles per day) or low traffic intensity (ca. 10-90 vehicles per day) associated to management and research activities. The frequencies of alarm calls and flock flushes were greater in areas of higher traffic intensity, which resulted in direct mortality at moderate vehicle speeds (<= 40 km/h). Parental feeding rates paralleled changes in traffic intensity, but contrary to our predictions. Indeed, feeding rates were highest in traffic-exposed nests, during working days and traffic rush-hours. Traffic-avoidance responses were systematic and likely involved costs (energy expenditure and mortality), but vehicle transit positively influenced the reproductive performance of bee-eaters through an increase of nestling feeding rates. Because the expected outcome of traffic on individual performance can be opposed when responses are monitored during mating (i.e. negative effect by increase of alarm calls and flock flushes) or nestling-feeding period (i.e. at least short-term positive effect by increase of nestling feeding rates), caution should be taken before inferring fitness consequences only from isolated behaviors or specific life history stages. PMID- 27706230 TI - Using Survival Analysis to Identify Risk Factors for Treatment Interruption among New and Retreatment Tuberculosis Patients in Kenya. AB - Despite high tuberculosis (TB) treatment success rate, treatment adherence is one of the major obstacles to tuberculosis control in Kenya. Our objective was to identify patient-related factors that were associated with time to TB treatment interruption and the geographic distribution of the risk of treatment interruption by county. Data of new and retreatment patients registered in TIBU, a Kenyan national case-based electronic data recording system, between 2013 and 2014 was obtained. Kaplan-Meier curves and log rank tests were used to assess the adherence patterns. Mixed-effects Cox proportional hazards modeling was used for multivariate analysis. Records from 90,170 patients were included in the study. The cumulative incidence of treatment interruption was 4.5% for new patients, and 8.5% for retreatment patients. The risk of treatment interruption was highest during the intensive phase of treatment. Having previously been lost to follow-up was the greatest independent risk factor for treatment interruption (HR: 4.79 [3.99, 5.75]), followed by being HIV-positive not on ART (HR: 1.96 [1.70, 2.26]) and TB relapse (HR: 1.70 [1.44, 2.00]). Male and underweight patients had high risks of treatment interruption (HR: 1.46 [1.35, 1.58]; 1.11 [1.03, 1.20], respectively). High rates of treatment interruption were observed in counties in the central part of Kenya while counties in the northeast had the lowest risk of treatment interruption. A better understanding of treatment interruption risk factors is necessary to improve adherence to treatment. Interventions should focus on patients during the intensive phase, patients who have previously been lost to follow-up, and promotion of integrated TB and HIV services among public and private facilities. PMID- 27706231 TI - Protective Effects of Acetylation on the Pathological Reactions of the Lens Crystallins with Homocysteine Thiolactone. AB - Various post-translational lens crystallins modifications result in structural and functional insults, contributing to the development of lens opacity and cataract disorders. Lens crystallins are potential targets of homocysteinylation, particularly under hyperhomocysteinemia which has been indicated in various eye diseases. Since both homocysteinylation and acetylation primarily occur on protein free amino groups, we applied different spectroscopic methods and gel mobility shift analysis to examine the possible preventive role of acetylation against homocysteinylation. Lens crystallins were extensively acetylated in the presence of acetic anhydride and then subjected to homocysteinylation in the presence of homocysteine thiolactone (HCTL). Extensive acetylation of the lens crystallins results in partial structural alteration and enhancement of their stability, as well as improvement of alpha-crystallin chaperone-like activity. In addition, acetylation partially prevents HCTL-induced structural alteration and aggregation of lens crystallins. Also, acetylation protects against HCTL-induced loss of alpha-crystallin chaperone activity. Additionally, subsequent acetylation and homocysteinylation cause significant proteolytic degradation of crystallins. Therefore, further experimentation is required in order to judge effectively the preventative role of acetylation on the structural and functional insults induced by homocysteinylation of lens crystallins. PMID- 27706232 TI - Cadmium-109 Radioisotope Adsorption onto Polypyrrole Coated Sawdust of Dryobalanops aromatic: Kinetics and Adsorption Isotherms Modelling. AB - A radiotracer study was conducted to investigate the removal characteristics of cadmium (109Cd) from aqueous solution by polypyrrole/ sawdust composite. Several factors such as solution pH, sorbent dosage, initial concentration, contact time, temperature and interfering metal ions were found to have influence on the adsorption process. The kinetics of adsorption was relatively fast, reaching equilibrium within 3 hours. A lowering of the solution pH reduced the removal efficiency from 99.3 to ~ 46.7% and an ambient temperature of 25 degrees C was found to be optimum for maximum adsorption. The presence of sodium and potassium ions inhibited 109Cd removal from its aqueous solution. The experimental data for 109Cd adsorption showed a very good agreement with the Langmuir isotherm and a pseudo-first order kinetic model. The surface condition of the adsorbent before and after cadmium loading was investigated using BET, FESEM and FTIR. Considering the low cost of the precursor's materials and the toxicity of 109Cd radioactive metal, polypyrrole synthesized on the sawdust of Dryobalanops aromatic could be used as an efficient adsorbent for the removal of 109Cd radioisotope from radionuclide-containing effluents. PMID- 27706233 TI - Dysregulation of Autophagy Contributes to Anal Carcinogenesis. AB - INTRODUCTION: Autophagy is an intracellular catabolic process that removes and recycles unnecessary/dysfunctional cellular components, contributing to cellular health and survival. Autophagy is a highly regulated cellular process that responds to several intracellular signals, many of which are deregulated by human papillomavirus (HPV) infection through the expression of HPV-encoded oncoproteins. This adaptive inhibitory response helps prevent viral clearance. A strong correlation remains between HPV infection and the development of squamous cell carcinoma (SCC) of the anus, particularly in HIV positive and other immunosuppressed patients. We hypothesize that autophagy is inhibited by HPV encoded oncoproteins thereby promoting anal carcinogenesis (Fig 1). MATERIALS AND METHODS: HPV16 transgenic mice (K14E6/E7) and non-transgenic mice (FVB/N), both of which do not spontaneously develop anal tumors, were treated topically with the chemical carcinogen, 7,12-Dimethylbenz[a]anthracene (DMBA), to induce anal cancer. The anuses at different time points of treatment (5, 10, 15 and 20 weeks) were analyzed using immunofluorescence (IF) for two key autophagy marker proteins (LC3beta and p62) in addition to histological grading. The anuses from the K14E6/E7 mice were also analyzed for visual evidence of autophagic activity by electron microscopy (EM). To see if there was a correlation to humans, archival anal specimens were assessed histologically for grade of dysplasia and then analyzed for LC3beta and p62 protein content. To more directly examine the effect of autophagic inhibition on anal carcinogenesis, nontransgenic mice that do not develop anal cancer with DMBA treatment were treated with a known pharmacologic inhibitor of autophagy, chloroquine, and examined for tumor development and analyzed by IF for autophagic proteins. RESULTS: Histologically, we observed the progression of normal anoderm to invasive SCC with DMBA treatment in K14E6/E7 mice but not in nontransgenic, syngeneic FVB/N background control mice. With the development of low-grade dysplasia in the K14E6/E7 mice, there was an increase in both punctate LC3beta and p62 expression while EM revealed increased autophagosomes without evidence of autophagolysosomes. These observations are consistent with autophagy being inhibited at a later stage in the autophagic process. In contrast, in high-grade dysplasia and SCC in the DMBA-treated K14E6/E7 mice, there were decreased levels of p62 with a continued increase in punctate LC3beta expression by IF, while autophagolysosomes were seen on EM, consistent with the process of autophagy proceeded to completion. Similar findings, including histological grade dependent changes in LC3beta and p62 expression, were noted with human samples upon analysis of IF. Finally, with pharmacologic inhibition of autophagy in DMBA-treated, nontrangenic FVB/N mice, there was a significant increase in anal cancer development similar to that observed in DMBA- treated K14E6/E7 mice. CONCLUSION: Autophagic dysregulation is noted early on in HPV-associated anal carcinogenesis (low-grade dysplasia), with normalization of the autophagic process arising in late stages of HPV-associated anal carcinogenesis (high-grade dysplasia and invasive carcinoma).

AB - We present a novel algorithm for optimizing the order in which Chinese characters are learned, one that incorporates the benefits of learning them in order of usage frequency and in order of their hierarchal structural relationships. We show that our work outperforms previously published orders and algorithms. Our algorithm is applicable to any scheduling task where nodes have intrinsic differences in importance and must be visited in topological order. PMID- 27706237 TI - Inducible Expression of the De-Novo Designed Antimicrobial Peptide SP1-1 in Tomato Confers Resistance to Xanthomonas campestris pv. vesicatoria. AB - Antimicrobial peptides (AMPs) are small peptides with less than 50 amino acids and are part of the innate immune response in almost all organisms, including bacteria, vertebrates, invertebrates and plants. AMPs are active against a broad spectrum of pathogens. The inducible expression of AMPs in plants is a promising approach to combat plant pathogens with minimal negative side effects, such as phytotoxicity or infertility. In this study, inducible expression of the de-novo designed AMP SP1-1 in Micro Tom tomato protected tomato fruits against bacterial spot disease caused by Xanthomonas campestris pv. vesicatoria. The peptide SP1-1 was targeted to the apoplast which is the primary infection site for plant pathogens, by fusing SP1-1 peptide to the signal peptide RsAFP1 of radish (Raphanus sativus). The pathogen inducibility of the expression was enabled by using an optimized inducible 4XW2/4XS promoter. As a result, the tomato fruits of independently generated SP1-1 transgenic lines were significantly more resistant to X. campestris pv. vesicatoria than WT tomato fruits. In transgenic lines, bacterial infection was reduced up to 65% in comparison to the infection of WT plants. Our study demonstrates that the combination of the 4XW2/4XS cis-element from parsley with the synthetic antimicrobial peptide SP1-1 is a good alternative to protect tomato fruits against infections with X. campestris pv. vesicatoria. PMID- 27706236 TI - RNA-Seq of Borrelia burgdorferi in Multiple Phases of Growth Reveals Insights into the Dynamics of Gene Expression, Transcriptome Architecture, and Noncoding RNAs. AB - Borrelia burgdorferi, the agent of Lyme disease, differentially expresses numerous genes and proteins as it cycles between mammalian hosts and tick vectors. Insights on regulatory mechanisms have been provided by earlier studies that examined B. burgdorferi gene expression patterns during cultivation. However, prior studies examined bacteria at only a single time point of cultivation, providing only a snapshot of what is likely a dynamic transcriptional program driving B. burgdorferi adaptations to changes during culture growth phases. To address that concern, we performed RNA sequencing (RNA Seq) analysis of B. burgdorferi cultures at early-exponential, mid-exponential, and early-stationary phases of growth. We found that expression of nearly 18% of annotated B. burgdorferi genes changed significantly during culture maturation. Moreover, genome-wide mapping of the B. burgdorferi transcriptome in different growth phases enabled insight on transcript boundaries, operon structures, and identified numerous putative non-coding RNAs. These RNA-Seq data are discussed and presented as a resource for the community of researchers seeking to better understand B. burgdorferi biology and pathogenesis. PMID- 27706235 TI - Age Effects on Cognitive and Physiological Parameters in Familial Caregivers of Alzheimer's Disease Patients. AB - OBJECTIVES: Older familial caregivers of Alzheimer's disease patients are subjected to stress-related cognitive and psychophysiological dysfunctions that may affect their quality of life and ability to provide care. Younger caregivers have never been properly evaluated. We hypothesized that they would show qualitatively similar cognitive and psychophysiological alterations to those of older caregivers. METHOD: The cognitive measures of 17 young (31-58 years) and 18 old (63-84 years) caregivers and of 17 young (37-57 years) and 18 old (62-84 years) non-caregiver controls were evaluated together with their salivary cortisol and dehydroepiandrosterone (DHEA) levels, as measured by radioimmunoassays and ELISA assays of brain-derived neurotrophic factor (BDNF) in serum. RESULTS: Although younger caregivers had milder impairments in memory and executive functions than older caregivers, their performances fell to the same or lower levels as those of the healthy older controls. Decreases in DHEA and BDNF levels were correlated with the cognitive dysfunctions observed in the older and younger caregivers, respectively. Cortisol at 10PM increased in both caregiver groups. DISCUSSION: Younger caregivers were prone to cognitive impairments similar to older caregivers, although the degree and the neuropsychological correlates of the cognitive dysfunctions were somewhat different between the two groups. This work has implications for caregiver and care-recipient health and for research on the neurobiology of stress-related cognitive dysfunctions. PMID- 27706238 TI - Involvement of the NLRC4-Inflammasome in Diabetic Nephropathy. AB - Diabetic nephropathy (DN) is the leading cause of end-stage kidney disease worldwide but current treatments remain suboptimal. The role of inflammation in DN has only recently been recognized. It has been shown that the NLRP3 inflammasome contributes to DN development by inducing interleukin (IL)-1beta processing and secretion. In an effort to understand other IL-1beta activating mechanism during DN development, we examined the role of the NLRC4-inflammasome in DN and found that NLRC4 is a parallel mechanism, in addition to the NLRP3 inflammasome, to induce pro-IL-1beta processing and activation. We found that the expression of NLRC4 is elevated in DN kidneys. NLRC4-deficiency results in diminished DN disease progression, as manifested by a decrease in blood glucose and albumin excretion, as well as preserved renal histology. We further found that DN kidneys have increased F4/80+ macrophages, increased IL-1beta production, and other signaling pathways related to kidney pathology such as activation of NF kappaB and MAP kinase pathways, all of which were rescued by NLRC4-deficiency. This study demonstrates NLRC4-driven IL-1beta production as critical for the progression of DN, which underscores the importance to target this pathway to alleviate this devastating disease. PMID- 27706239 TI - Spatial and Temporal Resolution of Global Protein Synthesis during HSV Infection Using Bioorthogonal Precursors and Click Chemistry. AB - We used pulse-labeling with the methionine analogue homopropargylglycine (HPG) to investigate spatiotemporal aspects of protein synthesis during herpes simplex virus (HSV) infection. In vivo incorporation of HPG enables subsequent selective coupling of fluorochrome-capture reagents to newly synthesised proteins. We demonstrate that HPG labeling had no effect on cell viability, on accumulation of test early or late viral proteins, or on overall virus yields. HPG pulse-labeling followed by SDS-PAGE analysis confirmed incorporation into newly synthesised proteins, while parallel processing by in situ cycloaddition revealed new insight into spatiotemporal aspects of protein localisation during infection. A striking feature was the rapid accumulation of newly synthesised proteins not only in a general nuclear pattern but additionally in newly forming sub-compartments represented by small discrete foci. These newly synthesised protein domains (NPDs) were similar in size and morphology to PML domains but were more numerous, and whereas PML domains were progressively disrupted, NPDs were progressively induced and persisted. Immediate-early proteins ICP4 and ICP0 were excluded from NPDs, but using an ICP0 mutant defective in PML disruption, we show a clear spatial relationship between NPDs and PML domains with NPDs frequently forming immediately adjacent and co-joining persisting PML domains. Further analysis of location of the chaperone Hsc70 demonstrated that while NPDs formed early in infection without overt Hsc70 recruitment, later in infection Hsc70 showed pronounced recruitment frequently in a coat-like fashion around NPDs. Moreover, while ICP4 and ICP0 were excluded from NPDs, ICP22 showed selective recruitment. Our data indicate that NPDs represent early recruitment of host and viral de novo translated protein to distinct structural entities which are precursors to the previously described VICE domains involved in protein quality control in the nucleus, and reveal new features from which we propose spatially linked platforms of newly synthesised protein processing after nuclear import. PMID- 27706240 TI - Retrospective Attention Interacts with Stimulus Strength to Shape Working Memory Performance. AB - Orienting attention retrospectively to selective contents in working memory (WM) influences performance. A separate line of research has shown that stimulus strength shapes perceptual representations. There is little research on how stimulus strength during encoding shapes WM performance, and how effects of retrospective orienting might vary with changes in stimulus strength. We explore these questions in three experiments using a continuous-recall WM task. In Experiment 1 we show that benefits of cueing spatial attention retrospectively during WM maintenance (retrocueing) varies according to stimulus contrast during encoding. Retrocueing effects emerge for supraliminal but not sub-threshold stimuli. However, once stimuli are supraliminal, performance is no longer influenced by stimulus contrast. In Experiments 2 and 3 we used a mixture-model approach to examine how different sources of error in WM are affected by contrast and retrocueing. For high-contrast stimuli (Experiment 2), retrocues increased the precision of successfully remembered items. For low-contrast stimuli (Experiment 3), retrocues decreased the probability of mistaking a target with distracters. These results suggest that the processes by which retrospective attentional orienting shape WM performance are dependent on the quality of WM representations, which in turn depends on stimulus strength during encoding. PMID- 27706241 TI - Intensity Thresholds on Raw Acceleration Data: Euclidean Norm Minus One (ENMO) and Mean Amplitude Deviation (MAD) Approaches. AB - OBJECTIVES: (1) To develop and internally-validate Euclidean Norm Minus One (ENMO) and Mean Amplitude Deviation (MAD) thresholds for separating sedentary behaviours from common light-intensity physical activities using raw acceleration data collected from both hip- and wrist-worn tri-axial accelerometers; and (2) to compare and evaluate the performances between the ENMO and MAD metrics. METHODS: Thirty-three adults [mean age (standard deviation (SD)) = 27.4 (5.9) years; mean BMI (SD) = 23.9 (3.7) kg/m2; 20 females (60.6%)] wore four accelerometers; an ActiGraph GT3X+ and a GENEActiv on the right hip; and an ActiGraph GT3X+ and a GENEActiv on the non-dominant wrist. Under laboratory-conditions, participants performed 16 different activities (11 sedentary behaviours and 5 light-intensity physical activities) for 5 minutes each. ENMO and MAD were computed from the raw acceleration data, and logistic regression and receiver-operating-characteristic (ROC) analyses were implemented to derive thresholds for activity discrimination. Areas under ROC curves (AUROC) were calculated to summarise performances and thresholds were assessed via executing leave-one-out-cross-validations. RESULTS: For both hip and wrist monitor placements, in comparison to the ActiGraph GT3X+ monitors, the ENMO and MAD values derived from the GENEActiv devices were observed to be slightly higher, particularly for the lower-intensity activities. Monitor-specific hip and wrist ENMO and MAD thresholds showed excellent ability for separating sedentary behaviours from motion-based light-intensity physical activities (in general, AUROCs >0.95), with validation indicating robustness. However, poor classification was experienced when attempting to isolate standing still from sedentary behaviours (in general, AUROCs <0.65). The ENMO and MAD metrics tended to perform similarly across activities and accelerometer brands. CONCLUSIONS: Researchers can utilise these robust monitor-specific hip and wrist ENMO and MAD thresholds, in order to accurately separate sedentary behaviours from common motion-based light-intensity physical activities. However, caution should be taken if isolating sedentary behaviours from standing is of particular interest. PMID- 27706242 TI - The Significance of Serum HER2 Levels at Diagnosis on Intrinsic Subtype-Specific Outcome of Operable Breast Cancer Patients. AB - PURPOSE: This study evaluated the association of serum HER2 (sHER2) levels at diagnosis with clinicopathologic parameters and disease free survival (DFS) in operable breast cancer patients according to intrinsic subtype. METHODS: The sHER2 levels were measured using a chemiluminescence immunoassay. The HER2 status in all tumor tissues was determined by immunohistochemistry, and confirmed in equivocal cases by fluorescence in situ. RESULTS: There were 436 consecutive stage I-III breast cancer patients with sHER2 result at diagnosis between Nov 2004 and Dec 2011. High sHER2 levels (>= 15 ng/ml) were reported in 52 patients (11.9%) and HER2 overexpression in tumor tissue was observed in 111 patients (25.5%). High sHER2 levels were associated significantly with advanced stage (P < 0.001), mastectomy (P = 0.012), neoadjuvant chemotherapy (P < 0.001), anti-HER2 therapy (P < 0.001) and hormone therapy (P = 0.022). The patients with high sHER2 levels had a worse DFS (P < 0.001). In multivariate analysis, high sHER2 levels were associated significantly with worse DFS (HR = 2.25, 95% CI 1.27-3.99, P = 0.005). High sHER2 levels were associated with worse DFS in the HR+/HER2-, HR+/HER2+ and HR-/HER2+ subtypes (P = 0.043, 0.003 and 0.041, respectively). CONCLUSIONS: These results show that the sHER2 level at diagnosis is a useful prognostic factor in patients with operable breast cancer, especially in the HR+/HER2-, HR+/HER2+ and HR-/HER2+ subtypes. PMID- 27706243 TI - Prognostic Significance of Modified Advanced Lung Cancer Inflammation Index (ALI) in Patients with Small Cell Lung Cancer_ Comparison with Original ALI. AB - BACKGROUND: Advanced lung cancer inflammation index (ALI, body mass index [BMI] x serum albumin/neutrophil-lymphocyte ratio [NLR]) has been shown to predict overall survival (OS) in small cell lung cancer (SCLC). CT enables skeletal muscle to be quantified, whereas BMI cannot accurately reflect body composition. The purpose was to evaluate prognostic value of modified ALI (mALI) using CT determined L3 muscle index (L3MI, muscle area at L3/height2) beyond original ALI. METHODS: L3MIs were calculated using the CT images of 186 consecutive patients with SCLC taken at diagnosis, and mALI was defined as L3MI x serum albumin/NLR. Using chi-squared test determined maximum cut-offs for low ALI and low mALI, the prognostic values of low ALI and low mALI were tested using Kaplan-Meier method and Cox proportional hazards analysis. Finally, deviance statistics was used to test whether the goodness of fit of the prognostic model is improved by adding mALI as an extra variable. RESULTS: Patients with low ALI (cut-off, 31.1, n = 94) had shorter OS than patients with high ALI (median, 6.8 months vs. 15.8 months; p < 0.001), and patients with low mALI (cut-off 67.7, n = 94) had shorter OS than patients with high mALI (median, 6.8 months vs. 16.5 months; p < 0.001). There was no significant difference in estimates of median survival time between low ALI and low mALI (z = 0.000, p = 1.000) and between high ALI and high mALI (z = 0.330, p = 0.740). Multivariable analysis showed that low ALI was an independent prognostic factor for shorter OS (HR, 1.67, p = 0.004), along with advanced age (HR, 1.49, p = 0.045), extensive disease (HR, 2.27, p < 0.001), supportive care only (HR, 7.86, p < 0.001), and elevated LDH (HR, 1.45, p = 0.037). Furthermore, goodness of fit of this prognostic model was not significantly increased by adding mALI as an extra variable (LR difference = 2.220, p = 0.136). CONCLUSION: The present study confirms mALI using CT-determined L3MI has no additional prognostic value beyond original ALI using BMI. ALI is a simple and useful prognostic indicator in SCLC.

AB - BACKGROUND AND AIMS: Large indels are commonly identified in patients but are not detectable by routine Sanger sequencing and panel sequencing. We specially designed a multi-gene panel that could simultaneously test known large indels in addition to ordinary variants, and reported the diagnostic yield in patients with intrahepatic cholestasis. METHODS: The panel contains 61 genes associated with cholestasis and 25 known recurrent large indels. The amplicon library was sequenced on Ion PGM system. Sequencing data were analyzed using a routine data analysis protocol and an internal program encoded for large indels test simultaneously. The validation phase was performed using 54 patients with known genetic diagnosis, including 5 with large insertions. At implement phase, 141 patients with intrahepatic cholestasis were evaluated. RESULTS: At validation phase, 99.6% of the variations identified by Sanger sequencing could be detected by panel sequencing. Following the routine protocol, 99.8% of false positives could be filtered and 98.8% of retained variations were true positives. Large insertions in the 5 patients with known genetic diagnosis could be correctly detected using the internal program. At implementation phase, 96.9% of the retained variations, following the routine protocol, were confirmed to be true. Twenty-nine patients received a potential genetic diagnosis when panel sequencing data were analyzed using the routine protocol. Two additional patients, who were found to harbor large insertions in SLC25A13, obtained a potential genetic diagnosis when sequencing data were further analyzed using the internal program. A total of 31 (22.0%) patients obtained a potential genetic diagnosis. Nine different genetic disorders were diagnosed, and citrin deficiency was the commonest. CONCLUSION: Specially designed multi-gene panel can correctly detect large indels simultaneously. By using it, we assigned a potential genetic diagnosis to 22.0% of patients with intrahepatic cholestasis. PMID- 27706245 TI - Characteristics of Retractions from Korean Medical Journals in the KoreaMed Database: A Bibliometric Analysis. AB - BACKGROUND: Flawed or misleading articles may be retracted because of either honest scientific errors or scientific misconduct. This study explored the characteristics of retractions in medical journals published in Korea through the KoreaMed database. METHODS: We retrieved retraction articles indexed in the KoreaMed database from January 1990 to January 2016. Three authors each reviewed the details of the retractions including the reason for retraction, adherence to retraction guidelines, and appropriateness of retraction. Points of disagreement were reconciled by discussion among the three. RESULTS: Out of 217,839 articles in KoreaMed published from 1990 to January 2016, the publication type of 111 articles was retraction (0.051%). Of the 111 articles (addressing the retraction of 114 papers), 58.8% were issued by the authors, 17.5% were jointly issued (author, editor, and publisher), 15.8% came from editors, and 4.4% were dispatched by institutions; in 5.3% of the instances, the issuer was unstated. The reasons for retraction included duplicate publication (57.0%), plagiarism (8.8%), scientific error (4.4%), author dispute (3.5%), and other (5.3%); the reasons were unstated or unclear in 20.2%. The degree of adherence to COPE's retraction guidelines varied (79.8%-100%), and some retractions were inappropriate by COPE standards. These were categorized as follows: retraction of the first published article in the case of duplicate publication (69.2%), authorship dispute (15.4%), errata (7.7%), and other (7.7%). CONCLUSION: The major reason for retraction in Korean medical journals is duplicate publication. Some retractions resulted from overreaction by the editors. Therefore, editors of Korean medical journals should take careful note of the COPE retraction guidelines and should undergo training on appropriate retraction practices. PMID- 27706246 TI - Extracellular Histone Released from Leukemic Cells Increases Their Adhesion to Endothelium and Protects them from Spontaneous and Chemotherapy-Induced Leukemic Cell Death. AB - INTRODUCTION: When leukocytes are stimulated by reactive oxygen species (ROS), they release nuclear contents into the extracellular milieu, called by extracellular traps (ET). The nuclear contents are mainly composed of the histone DNA complex and neutrophil elastase. This study investigated whether leukemic cells could release ET and the released histone could induce endothelial activation, eventually resulting in leukemic progression. METHODS: The circulating ET were measured in 80 patients with hematologic diseases and 40 healthy controls. ET formation and ROS levels were investigated during leukemic cell proliferation in vitro. Histone-induced endothelial adhesion molecules expression and cell survival were measured by flow cytometry. RESULTS: Acute leukemia patients had high levels of ET, which correlated with peripheral blast count. Leukemic cells produced high ROS levels and released extracellular histone, which was significantly blocked by antioxidants. Histone significantly induced 3 endothelial adhesion molecules expression, and promoted leukemic cell adhesion to endothelial cells, which was inhibited by histone inhibitors (heparin, polysialic acid, and activated protein C), neutralizing antibodies against these adhesion molecules, and a Toll like receptor(TLR)9 antagonist. When leukemic cells were co-cultured with endothelial cells, adherent leukemic cells showed better survival than the non-adherent ones, demonstrating that histone treated endothelial cells protected leukemic cells from both spontaneous and chemotherapy-induced death. CONCLUSION: Our data demonstrate for the first time that extracellular histone can be released from leukemic cells through a ROS dependent mechanism. The released histone promotes leukemic cell adhesion by inducting the surface expression of endothelial adhesion molecules and eventually protects leukemic cells from cell death. PMID- 27706248 TI - Democratizing Neurorehabilitation: How Accessible are Low-Cost Mobile-Gaming Technologies for Self-Rehabilitation of Arm Disability in Stroke? AB - Motor-training software on tablets or smartphones (Apps) offer a low-cost, widely available solution to supplement arm physiotherapy after stroke. We assessed the proportions of hemiplegic stroke patients who, with their plegic hand, could meaningfully engage with mobile-gaming devices using a range of standard control methods, as well as by using a novel wireless grip-controller, adapted for neurodisability. We screened all newly-diagnosed hemiplegic stroke patients presenting to a stroke centre over 6 months. Subjects were compared on their ability to control a tablet or smartphone cursor using: finger-swipe, tap, joystick, screen-tilt, and an adapted handgrip. Cursor control was graded as: no movement (0); less than full-range movement (1); full-range movement (2); directed movement (3). In total, we screened 345 patients, of which 87 satisfied recruitment criteria and completed testing. The commonest reason for exclusion was cognitive impairment. Using conventional controls, the proportion of patients able to direct cursor movement was 38-48%; and to move it full-range was 55-67% (controller comparison: p>0.1). By comparison, handgrip enabled directed control in 75%, and full-range movement in 93% (controller comparison: p<0.001). This difference between controllers was most apparent amongst severely-disabled subjects, with 0% achieving directed or full-range control with conventional controls, compared to 58% and 83% achieving these two levels of movement, respectively, with handgrip. In conclusion, hand, or arm, training Apps played on conventional mobile devices are likely to be accessible only to mildly-disabled stroke patients. Technological adaptations such as grip-control can enable more severely affected subjects to engage with self-training software. PMID- 27706247 TI - Nasopharyngeal Pneumococcal Carriage among Healthy Children in Cyprus Post Widespread Simultaneous Implementation of PCV10 and PCV13 Vaccines. AB - The objective of the study was to describe the incidence of pneumococcal nasopharyngeal carriage, serotype distribution and antibiotic resistance profile of pneumococcal nasopharyngeal isolates in healthy children aged 6 to 36 months following the implementation of conjugate vaccines. A nasopharyngeal swab was collected from 1105 healthy children following a stratified random sampling between September 2013 and April 2014. Demographics, vaccination status and data on possible risk factors were recorded. Isolates were serotyped and tested for antibiotic susceptibility. The nasopharyngeal carriage rate was 25.3%. Among 1105 children enrolled, 393 had received PCV13 and 685 PCV10. The prevailing isolated serotypes were: 23A (14.3%), 15A (8.9%), 6C (8.6%), 23B (7.5%), 19A (5.4%) and 15B (5%). The proportion of non-vaccine serotypes, PCV10 serotypes, PCV13 additional serotypes (3, 6A, 19A) was 76.8%, 2.1% and 10.4% respectively. Although children, who were fully or partially vaccinated with PCV13, were 63% less likely to be colonized with additional PCV13 serotypes compared to those vaccinated with PCV10, the difference is not significant (95%Cl = 0.14-1.02, p = 0.053). The highest antibiotic non-susceptible rates were found for erythromycin (28.2%) and penicillin (27.9%). The overall multidrug resistance rate was 13.2%, with serotypes 24F (4/6), 15A (14/25) and 19A (6/15) being the main contributors. Carriage rate was similar between children vaccinated with PCV10 or PCV13. The high incidence of 15A serotype which is also multidrug resistant should be underlined. Ongoing surveillance is needed to monitor the dynamics on nasopharyngeal carriage. PMID- 27706249 TI - Carbon Costs of Constitutive and Expressed Resistance to a Non-Native Pathogen in Limber Pine. AB - Increasing the frequency of resistance to the non-native fungus Cronartium ribicola (causative agent of white pine blister rust, WPBR) in limber pine populations is a primary management objective to sustain high-elevation forest communities. However, it is not known to what extent genetic disease resistance is costly to plant growth or carbon economy. In this study, we measured growth and leaf-level physiology in (1) seedling families from seed trees that have previously been inferred to carry or not carry Cr4, the dominant R gene allele conferring complete, gene-for-gene resistance to WPBR in limber pine, and (2) populations that were and were not infected with C. ribicola. We found that, in the absence of C. ribicola exposure, there was no significant difference in carbon relations between families born from seed trees that harbor the resistance allele compared to those that lack it, either to plant growth and phenology or leaf-level photosynthetic traits. However, post-infection with C. ribicola, growth was significantly reduced in inoculation survivors expressing complete resistance compared to uninoculated seedlings. Furthermore, inoculation survivors exhibited significant increases in a suite of traits including photosynthetic rate, respiration rate, leaf N, and stomatal conductance and a decrease in photosynthetic water-use efficiency. The lack of constitutive carbon costs associated with Cr4 resistance in non-stressed limber pine is consistent with a previous report that the R gene allele is not under selection in the absence of C. ribicola and suggests that host resistance may not bear a constitutive cost in pathosystems that have not coevolved. However, under challenge by C. ribicola, complete resistance to WPBR in limber pine has a significant cost to plant growth, though enhanced carbon acquisition post-infection may offset this somewhat. These costs and effects on performance further complicate predictions of this species' response in warmer future climates in the presence of WPBR. PMID- 27706250 TI - A New Giant Titanosauria (Dinosauria: Sauropoda) from the Late Cretaceous Bauru Group, Brazil. AB - Titanosaurian dinosaurs include some of the largest land-living animals that ever existed, and most were discovered in Cretaceous deposits of Argentina. Here we describe the first Brazilian gigantic titanosaur, Austroposeidon magnificus gen. et sp. nov., from the Late Cretaceous Presidente Prudente Formation (Bauru Group, Parana Basin), Sao Paulo State, southeast Brazil. The size of this animal is estimated around 25 meters. It consists of a partial vertebral column composed by the last two cervical and the first dorsal vertebrae, all fairly complete and incomplete portions of at least one sacral and seven dorsal elements. The new species displays four autapomorphies: robust and tall centropostzygapophyseal laminae (cpol) in the last cervical vertebrae; last cervical vertebra bearing the posterior centrodiapophyseal lamina (pcdl) bifurcated; first dorsal vertebra with the anterior and posterior centrodiapophyseal laminae (acdl/pcdl) curved ventrolaterally, and the diapophysis reaching the dorsal margin of the centrum; posterior dorsal vertebra bearing forked spinoprezygapophyseal laminae (sprl). The phylogenetic analysis presented here reveals that Austroposeidon magnificus is the sister group of the Lognkosauria. CT scans reveal some new osteological internal features in the cervical vertebrae such as the intercalation of dense growth rings with camellae, reported for the first time in sauropods. The new taxon further shows that giant titanosaurs were also present in Brazil during the Late Cretaceous and provides new information about the evolution and internal osteological structures in the vertebrae of the Titanosauria clade. PMID- 27706251 TI - Risk Factors for Non-Adherence to cART in Immigrants with HIV Living in the Netherlands: Results from the ROtterdam ADherence (ROAD) Project. AB - In the Netherlands, immigrant people living with HIV (PLWH) have poorer psychological and treatment outcomes than Dutch PLWH. This cross-sectional field study examined risk factors for non-adherence to combination Antiretroviral Therapy (cART) among immigrant PLWH. First and second generation immigrant PLWH attending outpatient clinics at two HIV-treatment centers in Rotterdam were selected for this study. Socio-demographic and clinical characteristics for all eligible participants were collected from an existing database. Trained interviewers subsequently completed questionnaires together with consenting participants (n = 352) to gather additional data on socio-demographic characteristics, psychosocial variables, and self-reported adherence to cART. Univariable and multivariable logistic regression analyses were conducted among 301 participants who had used cART >=6 months prior to inclusion. Independent risk factors for self-reported non-adherence were (I) not having attended formal education or only primary school (OR = 3.25; 95% CI: 1.28-8.26, versus University), (II) experiencing low levels of social support (OR = 2.56; 95% CI: 1.37-4.82), and (III) reporting low treatment adherence self-efficacy (OR = 2.99; 95% CI: 1.59-5.64). Additionally, HIV-RNA >50 copies/ml and internalized HIV related stigma were marginally associated (P<0.10) with non-adherence (OR = 2.53; 95% CI: 0.91-7.06 and OR = 1.82; 95% CI: 0.97-3.43). The findings that low educational attainment, lack of social support, and low treatment adherence self efficacy are associated with non-adherence point to the need for tailored supportive interventions. Establishing contact with peer immigrant PLWH who serve as role models might be a successful intervention for this specific population. PMID- 27706252 TI - Predictors of HIV Testing among Youth in Sub-Saharan Africa: A Cross-Sectional Study. AB - INTRODUCTION: In spite of a high prevalence of HIV infection among adolescents and young adults in sub-Saharan Africa, uptake of HIV testing and counseling among youth in the region remains sub-optimal. The objective of this study was to assess factors that influence uptake of HIV testing and counseling among youth aged 15-24 years in sub-Saharan Africa. METHODS: This study used the Demographic and Health Survey (DHS) data from countries that represent four geographic regions of sub-Saharan Africa: Congo (Brazzaville), representing central Africa (DHS 2011-2012); Mozambique, representing southern Africa (DHS 2011); Nigeria, representing western Africa (DHS 2013); and Uganda, representing eastern Africa (DHS 2011). Analyses were restricted to 23,367 male and female respondents aged 15-24 years with complete data on the variables of interest. Chi-square tests and logistic regression models were used to assess predictors of HIV testing. Statistical significance was set at p< 0.01. RESULTS: The analysis revealed that a majority of the respondents were female (78.1%) and aged 20-24-years (60.7%). Only a limited proportion of respondents (36.5%) had ever tested for HIV and even fewer (25.7%) demonstrated comprehensive knowledge of HIV/AIDS. There was a significant association between HIV testing and respondents' gender, age, age at sexual debut, and comprehensive knowledge of HIV in the pooled sample. Older youth (adjusted OR (aOR) = 2.19; 99% CI = 1.99-2.40) and those with comprehensive knowledge of HIV (aOR = 1.98; 1.76-2.22) had significantly higher odds of ever being tested for HIV than younger respondents and those with limited HIV/AIDS knowledge respectively. Furthermore, men had lower odds of HIV testing than women (aOR = 0.32; 0.28-0.37). CONCLUSIONS: Reaching youth in sub-Saharan Africa for HIV testing continues to be a challenge. Public health programs that seek to increase HIV counseling and testing among youth should pay particular attention to efforts that target high-risk subpopulations of youth. The results further suggest that these initiatives would be strengthened by including strategies to increase HIV comprehensive knowledge. PMID- 27706253 TI - Morphological Characteristics of Electrophysiologically Characterized Layer Vb Pyramidal Cells in Rat Barrel Cortex. AB - Layer Vb pyramidal cells are the major output neurons of the neocortex and transmit the outcome of cortical columnar signal processing to distant target areas. At the same time they contribute to local tactile information processing by emitting recurrent axonal collaterals into the columnar microcircuitry. It is, however, not known how exactly the two types of pyramidal cells, called slender tufted and thick-tufted, contribute to the local circuitry. Here, we investigated in the rat barrel cortex the detailed quantitative morphology of biocytin-filled layer Vb pyramidal cells in vitro, which were characterized for their intrinsic electrophysiology with special emphasis on their action potential firing pattern. Since we stained the same slices for cytochrome oxidase, we could also perform layer- and column-related analyses. Our results suggest that in layer Vb the unambiguous action potential firing patterns "regular spiking (RS)" and "repetitive burst spiking (RB)" (previously called intrinsically burst spiking) correlate well with a distinct morphology. RS pyramidal cells are somatodendritically of the slender-tufted type and possess numerous local intralaminar and intracolumnar axonal collaterals, mostly reaching layer I. By contrast, their transcolumnar projections are less well developed. The RB pyramidal cells are somatodendritically of the thick-tufted type and show only relatively sparse local axonal collaterals, which are preferentially emitted as long horizontal or oblique infragranular collaterals. However, contrary to many previous slice studies, a substantial number of these neurons also showed axonal collaterals reaching layer I. Thus, electrophysiologically defined pyramidal cells of layer Vb show an input and output pattern which suggests RS cells to be more "locally segregating" signal processors whereas RB cells seem to act more on a "global integrative" scale. PMID- 27706254 TI - Novel Hydrophobin Fusion Tags for Plant-Produced Fusion Proteins. AB - Hydrophobin fusion technology has been applied in the expression of several recombinant proteins in plants. Until now, the technology has relied exclusively on the Trichoderma reesei hydrophobin HFBI. We screened eight novel hydrophobin tags, T. reesei HFBII, HFBIII, HFBIV, HFBV, HFBVI and Fusarium verticillioides derived HYD3, HYD4 and HYD5, for production of fusion proteins in plants and purification by two-phase separation. To study the properties of the hydrophobins, we used N-terminal and C-terminal GFP as a fusion partner. Transient expression of the hydrophobin fusions in Nicotiana benthamiana revealed large variability in accumulation levels, which was also reflected in formation of protein bodies. In two-phase separations, only HFBII and HFBIV were able to concentrate GFP into the surfactant phase from a plant extract. The separation efficiency of both tags was comparable to HFBI. When the accumulation was tested side by side, HFBII-GFP gave a better yield than HFBI-GFP, while the yield of HFBIV-GFP remained lower. Thus we present here two alternatives for HFBI as functional fusion tags for plant-based protein production and first step purification. PMID- 27706255 TI - The Effect of Albumin on MRP2 and BCRP in the Vesicular Transport Assay. AB - The ABC transporters multidrug resistance associated protein 2 (MRP2) and breast cancer resistance protein (BCRP) are of interest in drug development, since they affect the pharmacokinetics of several drugs. Membrane vesicle transport assays are widely used to study interactions with these proteins. Since albumin has been found to affect the kinetics of metabolic enzymes in similar membrane preparations, we investigated whether albumin affects the kinetic parameters of efflux transport. We found that albumin increased the Vmax of 5(6)-carboxy-2',7' dichlorofluorescein (CDCF) and estradiol-17-beta-D-glucuronide uptake into MRP2 vesicles in the presence of 0.1% bovine serum albumin (BSA) by 2 and 1.5-fold, respectively, while BSA increased Lucifer yellow uptake by 30% in BCRP vesicles. Km values increased slightly, but the change was not statistically significant. The effect of BSA on substrate uptake was dependent on the vesicle amount, while increasing BSA concentration did not significantly improve substrate uptake. These results indicate a minor effect of albumin on MRP2 and BCRP, but it should be considered if albumin is added to transporter assays for example as a solubilizer, since the effect may be substrate or transporter specific. PMID- 27706256 TI - Time Series Analysis of Hemorrhagic Fever with Renal Syndrome: A Case Study in Jiaonan County, China. AB - Exact prediction of Hemorrhagic fever with renal syndrome (HFRS) epidemics must improve to establish effective preventive measures in China. A Seasonal Autoregressive Integrated Moving Average (SARIMA) model was applied to establish a highly predictive model of HFRS. Meteorological factors were considered external variables through a cross correlation analysis. Then, these factors were included in the SARIMA model to determine if they could improve the predictive ability of HFRS epidemics in the region. The optimal univariate SARIMA model was identified as (0,0,2)(1,1,1)12. The R2 of the prediction of HFRS cases from January 2014 to December 2014 was 0.857, and the Root mean square error (RMSE) was 2.708. However, the inclusion of meteorological variables as external regressors did not significantly improve the SARIMA model. This result is likely because seasonal variations in meteorological variables were included in the seasonal characteristics of the HFRS itself. PMID- 27706257 TI - The Relationship between Mating System and Genetic Diversity in Diploid Sexual Populations of Cyrtomium falcatum in Japan. AB - The impact of variation in mating system on genetic diversity is a well-debated topic in evolutionary biology. The diploid sexual race of Cyrtomium falcatum (Japanese holly fern) shows mating system variation, i.e., it displays two different types of sexual expression (gametangia formation) in gametophytes: mixed (M) type and separate (S) type. We examined whether there is variation in the selfing rate among populations of this species, and evaluated the relationship between mating system, genetic diversity and effective population size using microsatellites. In this study, we developed eight new microsatellite markers and evaluated genetic diversity and structure of seven populations (four M-type and three S-type). Past effective population sizes (Ne) were inferred using Approximate Bayesian computation (ABC). The values of fixation index (FIS), allelic richness (AR) and gene diversity (h) differed significantly between the M type (FIS: 0.626, AR: 1.999, h: 0.152) and the S-type (FIS: 0.208, AR: 2.718, h: 0.367) populations (when admixed individuals were removed from two populations). Although evidence of past bottleneck events was detected in all populations by ABC, the current Ne of the M-type populations was about a third of that of the S type populations. These results suggest that the M-type populations have experienced more frequent bottlenecks, which could be related to their higher colonization ability via gametophytic selfing. Although high population differentiation among populations was detected (FST = 0.581, F'ST = 0.739), there was no clear genetic differentiation between the M- and S-types. Instead, significant isolation by distance was detected among all populations. These results suggest that mating system variation in this species is generated by the selection for single spore colonization during local extinction and recolonization events and there is no genetic structure due to mating system. PMID- 27706258 TI - HAG (Homoharringtonine, Cytarabine, G-CSF) Regimen for the Treatment of Acute Myeloid Leukemia and Myelodysplastic Syndrome: A Meta-Analysis with 2,314 Participants. AB - BACKGROUND: In China, the combination of homoharringtonine, cytarabine, and G-CSF (HAG) has been extensively applied for treatment of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). METHODS: We performed a meta-analysis of 2,314 patients (AML, n = 1754; MDS, n = 560) to determine the overall safety and efficacy of this regimen. RESULTS: The complete response (CR) rate of AML patients (53%) was significantly higher than that of MDS/transformed-AML patients (45%; P = 0.007). The CR rate of patients with newly diagnosed AML (62%) was significantly higher than in patients with relapsed/refractory AML (50%; P = 0.001). There were no significant difference in CR rates between elderly AML patients (54%) and all AML patients (P = 0.721). When compared with non-HAG regimens for AML/MDS induction therapy, the CR rate of patients treated with HAG was significantly higher than in treated with intensive chemotherapy (P = 0.000). No significant differences in CR rates were observed between patients treated with HAG and those treated with CAG (cytarabine, aclarubicin, G-CSF) regimens (P = 0.073). HAG regimen was well tolerated, with early death (ED) in 2%, grade IV myelosurrpression in 52% and infection in 50%. Reports of ED and rates of myelosuppression were reduced as compared with intensive chemotherapy (P = 0.000 and P = 0.000, respectively). CONCLUSION: The HAG regimen is an effective and safe regimen for the treatment of AML and MDS, and appears to be more effective and better tolerated than intensive chemotherapy. Future randomized controlled trials and further meta-analyses are strongly needed to confirm its efficacy and safety, especially in comparison with intensive chemotherapy. PMID- 27706259 TI - Augmented Growth Hormone Secretion and Stat3 Phosphorylation in an Aryl Hydrocarbon Receptor Interacting Protein (AIP)-Disrupted Somatotroph Cell Line. AB - Aryl hydrocarbon receptor interacting protein (AIP) is thought to be a tumor suppressor gene, as indicated by a mutational analysis of pituitary somatotroph adenomas. However, the physiological significance of AIP inactivation in somatotroph cells remains unclear. Using CRISPR/Cas9, we identified a GH3 cell clone (termed GH3-FTY) in which Aip was genetically disrupted, and subsequently investigated its character with respect to growth hormone (Gh) synthesis and proliferation. Compared with GH3, GH3-FTY cells showed remarkably increased Gh production and a slight increase in cell proliferation. Gh-induced Stat3 phosphorylation is known to be a mechanism of Gh oversecretion in GH3. Interestingly, phosphorylated-Stat3 expression in GH3-FTY cells was increased more compared with GH3 cells, suggesting a stronger drive for this mechanism in GH3-FTY. The phenotypes of GH3-FTY concerning Gh overproduction, cell proliferation, and increased Stat3 phosphorylation were significantly reversed by the exogenous expression of Aip. GH3-FTY cells were less sensitive to somatostatin than GH3 cells in the suppression of cell proliferation, which might be associated with the reduced expression of somatostatin receptor type 2. GH3 FTY xenografts in BALB/c nude mice (GH3-FTY mice) formed more mitotic somatotroph tumors than GH3 xenografts (GH3 mice), as also evidenced by increased Ki67 scores. GH3-FTY mice were also much larger and had significantly higher plasma Gh levels than GH3 mice. Furthermore, GH3-FTY mice showed relative insulin resistance compared with GH3 mice. In conclusion, we established a somatotroph cell line, GH3-FTY, which possessed prominent Gh secretion and mitotic features associated with the disruption of Aip. PMID- 27706260 TI - Comparison of Two Different Modes of Active Recovery on Muscles Performance after Fatiguing Exercise in Mountain Canoeist and Football Players. AB - BACKGROUND: The aim of this study is to assess if the application of different methods of active recovery (working the same or different muscle groups from those which were active during fatiguing exercise) results in significant differences in muscle performance and if the efficiency of the active recovery method is dependent upon the specific sport activity (training loads). DESIGN: A parallel group non-blinded trial with repeated measurements. METHODS: Thirteen mountain canoeists and twelve football players participated in this study. Measurements of the bioelectrical activity, torque, work and power of the vastus lateralis oblique, vastus medialis oblique, and rectus femoris muscles were performed during isokinetic tests at a velocity of 90 degrees /s. RESULTS: Active legs recovery in both groups was effective in reducing fatigue from evaluated muscles, where a significant decrease in fatigue index was observed. The muscles peak torque, work and power parameters did not change significantly after both modes of active recovery, but in both groups significant decrease was seen after passive recovery. CONCLUSIONS: We suggest that 20 minutes of post-exercise active recovery involving the same muscles that were active during the fatiguing exercise is more effective in fatigue recovery than active exercise using the muscles that were not involved in the exercise. Active arm exercises were less effective in both groups which indicates a lack of a relationship between the different training regimens and the part of the body which is principally used during training. PMID- 27706262 TI - The 300 Most-Cited Articles in Implant Dentistry. AB - PURPOSE: The purpose of this study was to review and evaluate the characteristics of the 300 most-cited articles that have been published in the most important implant dentistry journals. MATERIALS AND METHODS: A search and selection of the most-cited articles up to October 2014 was conducted for implant journals with the highest impact factors, according to the ISI Web of Science. The 300-most cited articles were evaluated according to the most commonly studied topics and methodological designs used. The most-cited journals and the number of articles cited by year were calculated. Descriptive statistics were used to summarize the results. RESULTS: The most-cited topics consisted of implant success/survival and guided bone regeneration, and the most-cited methodological designs were case series and cohort studies. The most frequently referenced journal was The International Journal of Oral and Maxillofacial Implants, with 47% of the citations, and the period with the most citations was 1996 to 2000. CONCLUSION: Longitudinal studies of success and survival have had great scientific impact on the practice of implant dentistry. Awareness of the most-cited articles in implant dentistry will contribute to scientific advances, as it serves to identify the most researched areas, the most frequently used study designs, and areas that require further research. PMID- 27706261 TI - Homogeneous Inflammatory Gene Profiles Induced in Human Dermal Fibroblasts in Response to the Three Main Species of Borrelia burgdorferi sensu lato. AB - In Lyme borreliosis, the skin is the key site for bacterial inoculation by the infected tick and for cutaneous manifestations. We previously showed that different strains of Borrelia burgdorferi sensu stricto isolated from tick and from different clinical stages of the Lyme borreliosis (erythema migrans, and acrodermatitis chronica atrophicans) elicited a very similar transcriptional response in normal human dermal fibroblasts. In this study, using whole transcriptome microarray chips, we aimed to compare the transcriptional response of normal human dermal fibroblasts stimulated by 3 Borrelia burgdorferi sensu lato strains belonging to 3 main pathogenic species (B. afzelii, B. garinii and B. burgdorferi sensu stricto) in order to determine whether "species-related" inflammatory pathways could be identified. The three Borrelia strains tested exhibited similar transcriptional profiles, and no species-specific fingerprint of transcriptional changes in fibroblasts was observed. Conversely, a common core of chemokines/cytokines (CCL2, CXCL1, CXCL2, CXCL6, CXCL10, IL-6, IL-8) and interferon-related genes was stimulated by all the 3 strains. Dermal fibroblasts appear to play a key role in the cutaneous infection with Borrelia, inducing a homogeneous inflammatory response, whichever Borrelia species was involved. PMID- 27706264 TI - Three-Dimensional Accuracy of Digital Implant Impressions: Effects of Different Scanners and Implant Level. AB - PURPOSE: To compare the three-dimensional (3D) accuracy of conventional direct implant impressions with digital implant impressions from three intraoral scanners, as well as different implant levels-bone level (BL) and tissue level (TL). MATERIALS AND METHODS: Two-implant master models were used to simulate a threeunit implant-supported fixed dental prosthesis. Conventional test models were made with direct impression copings and polyether impressions. Scan bodies were hand-tightened onto master models and scanned with the three scanners. This was done for the TL and BL test groups, for a total of eight test groups (n = 5 each). A coordinate measuring machine measured linear distortions (dx, dy, dz), global linear distortion (dR), angular distortions (dthetay, dthetax), and absolute angular distortions (Absdthetay, Absdthetax) between the master models, test models, and .stl files of the digital scans. RESULTS: The mean dR ranged from 35 to 66 MUm; mean dthetay angular distortions ranged from -0.186 to 0.315 degrees; and mean dthetax angular distortions ranged from -0.206 to 0.164 degrees. Two-way analysis of variance showed that the impression type had a significant effect on dx, dz, and Absdthetay, and the implant level had a significant effect on dx and Absdthetax (P < .05). Among the BL groups, the mean dR of the conventional group was lower than and significantly different from the digital test groups (P = .010), while among the TL groups, there was no statistically significant difference (P = .572). CONCLUSION: The 3D accuracy of implant impressions varied according to the impression technique and implant level. For BL test groups, the conventional impression group had significantly lower distortion than the digital impression groups. Among the digital test groups, the TR system had comparable mean linear and absolute angular distortions to the other two systems but exhibited the smallest standard deviations. PMID- 27706263 TI - Gene-Activated Titanium Surfaces Promote In Vitro Osteogenesis. AB - PURPOSE: Commercially pure titanium (CpTi) and its alloys possess favorable mechanical and biologic properties for use as implants in orthopedics and dentistry. However, failures in osseointegration still exist and are common in select individuals with risk factors such as smoking. Therefore, in this study, a proposal was made to enhance the potential for osseointegration of CpTi discs by coating their surfaces with nanoplexes comprising polyethylenimine (PEI) and plasmid DNA (pDNA) encoding bone morphogenetic protein-2 (pBMP-2). MATERIALS AND METHODS: The nanoplexes were characterized for size and surface charge with a range of N/P ratios (the molar ratio of amine groups of PEI to phosphate groups in pDNA backbone). CpTi discs were surface characterized for morphology and composition before and after nanoplex coating using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), and X-ray powder diffraction (XRD). The cytotoxicity and transfection ability of CpTi discs coated with nanoplexes of varying N/P ratios in human bone marrow-derived mesenchymal stem cells (BMSCs) was measured via MTS assays and flow cytometry, respectively. RESULTS: The CpTi discs coated with nanoplexes prepared at an N/P ratio of 10 (N/P-10) were considered optimal, resulting in 75% cell viability and 14% transfection efficiency. Enzyme-linked immunosorbent assay results demonstrated a significant enhancement in BMP-2 protein secretion by BMSCs 7 days posttreatment with PEI/pBMP-2 nanoplexes (N/P-10) compared to the controls, and real-time PCR data demonstrated that the BMSCs treated with PEI/pBMP-2 nanoplex coated CpTi discs resulted in an enhancement of Runx-2, alkaline phosphatase, and osteocalcin gene expressions on day 7 posttreatment. In addition, these BMSCs demonstrated enhanced calcium deposition on day 30 posttreatment as determined by qualitative (alizarin red staining) and quantitative (atomic absorption spectroscopy) assays. CONCLUSION: It can be concluded that PEI/pBMP-2 nanoplex (N/P-10)-coated CpTi discs have the potential to induce osteogenesis and enhance osseointegration. PMID- 27706265 TI - Precision Fit of Screw-Retained Implant-Supported Fixed Dental Prostheses Fabricated by CAD/CAM, Copy-Milling, and Conventional Methods. AB - PURPOSE: The aim of this study was to evaluate the effectiveness of fabrication methods (computer-aided design/computer-aided manufacture [CAD/CAM], copy milling, and conventional casting) in the fit accuracy of three-unit, screw retained fixed dental prostheses. MATERIALS AND METHODS: Sixteen three-unit implant-supported screw-retained frameworks were fabricated to fit an in vitro model. Eight frameworks were fabricated using the CAD/CAM system, four in zirconia and four in cobalt-chromium. Four zirconia frameworks were fabricated using the copy-milled system, and four were cast in cobalt-chromium using conventional casting with premachined abutments. The vertical and horizontal misfit at the implant-framework interface was measured using scanning electron microscopy at *250. The results for vertical misfit were analyzed using Kruskal Wallis and Mann-Whitney tests. The horizontal misfits were categorized as underextended, equally extended, or overextended. Statistical analysis established differences between groups according to the chi-square test (alpha = .05). RESULTS: The mean vertical misfit was 5.9 +/- 3.6 MUm for CAD/CAM fabricated zirconia, 1.2 +/- 2.2 MUm for CAD/CAM-fabricated cobalt-chromium frameworks, 7.6 +/- 9.2 MUm for copy-milling-fabricated zirconia frameworks, and 11.8 (9.8) MUm for conventionally fabricated frameworks. The Mann-Whitney test revealed significant differences between all but the zirconia-fabricated frameworks. A significant association was observed between the horizontal misfits and the fabrication method. The percentage of horizontal misfits that were underextended and overextended was higher in milled zirconia (83.3%), CAD/CAM cobaltchromium (66.7%), cast cobalt-chromium (58.3%), and CAD/CAM zirconia (33.3%) frameworks. CONCLUSION: CAD/CAM-fabricated frameworks exhibit better vertical misfit and low variability compared with copy-milled and conventionally fabricated frameworks. The percentage of interfaces equally extended was higher when CAD/CAM and zirconia were used. PMID- 27706266 TI - Intermittent Parathyroid Hormone Improves Bone Formation Around Titanium Implants in Osteoporotic Rat Maxillae. AB - PURPOSE: Parathyroid hormone (PTH) plays an important role in the treatment of osteoporosis due to its anabolic effect. In this study, PTH was administered intermittently to rats with ovariectomy-induced osteoporosis, titanium implants were placed into the rat maxillae, and the response of surrounding bone was evaluated. MATERIALS AND METHODS: A total of 30 female 8-week-old Sprague-Dawley rats were either ovariectomized to induce osteoporosis or sham operated. After 8 weeks, the upper right first molar was extracted and after a 4-week healing period an implant was placed. The animals were then divided into three groups: the PTH group (n = 10), which had been ovariectomized and received postimplant PTH; the OVX group (n = 10), which had been ovariectomized but did not receive postimplant PTH; and the control group (n = 10), which had been sham operated only (n = 10). Following implant placement, the rats in the PTH group received intermittent doses (three times a week) of PTH (30 MUg/kg) subcutaneously in the dorsum. All the rats were sacrificed 4 weeks after implantation and specimens of the peri-implant maxillary bone were harvested, including the implant. Samples were evaluated by histomorphometric analysis and three-dimensional microcomputed tomography. RESULTS: Histomorphometric results showed that the mean bone area per tissue area (BA/TA) was 54.16% +/- 2.2% in the PTH group and 45.24% +/- 6.3% in the OVX group. The percentage of bone-to-implant contact (BIC) was 45.58% +/- 9.4% in the PTH group and 32.00% +/- 10.9% in the OVX group. Mean BA/TA and mean BIC values in the PTH group were higher than those in the OVX group; however, the differences were not statistically significant (P > .05). Microstructural data also showed differences between the groups. Bone volume was greater and trabecular bone was thicker in the PTH group than in the OVX group and more trabeculae were found in the PTH group. Bone mineral density was also higher in the PTH group. However, statistical analysis failed to show a significant difference between these two groups in any parameters other than trabecular thickness (P = .023). CONCLUSION: Despite the limitations of this study, intermittent PTH administration in humans may be helpful in accelerating new bone formation around implants. PTH treatment could improve clinical outcomes when dental implants are placed in jaws with low-quality bone. PMID- 27706267 TI - Changes in Lip Profile of Edentulous Patients After Placement of Maxillary Implant-Supported Fixed Prosthesis: Is a Wax Try-in a Reliable Diagnostic Tool? AB - PURPOSE: A diagnostic wax try-in has been recommended to correctly design the future prosthesis for edentulous maxillae and to predict its effect on the supporting oral tissues. The objectives of this study were to analyze (1) the reliability of this diagnostic tool in planning fixed implant-supported prostheses and (2) the amount of prosthetic compensation required. MATERIALS AND METHODS: Nine female patients participated in this prospective study (mean age, 53.6 years). After anamnesis, clinical examination, and preoperative analysis, the patients underwent preoperative prosthetic preparation, and the wax try-in was fabricated. To evaluate the efficiency of the diagnostic wax try-in, three profile cephalograms were taken of each patient: (1) with the initial conventional prosthesis, (2) with the wax try-in, and (3) with the implant supported prosthesis. Two analyses were carried out for the assessment of lip support: the nasolabial angle and Steiner's S-line. To analyze the amount of prosthetic compensation, two measurements-vertical and horizontal distances- were obtained for each wax try-in and final prosthesis. RESULTS: For the Steiner's S line, the results of the statistical tests indicated no significant difference between the initial and final prosthesis for the upper (P = .237) and lower lips (P = .237), and between the wax try-in and final prosthesis for the upper (P = .463) and lower lips (P = .463). Regarding the nasolabial angle, the results of the statistical tests indicated no significant difference between the initial and final prosthesis (P = .594), and between the wax try-in and final prosthesis (P = .800). Regarding prosthetic compensation, the results of the statistical test indicated no significant difference between the vertical (P = .753) and horizontal evaluations (P = .855) carried out for the wax try-in and those for the final prosthesis. CONCLUSION: On the basis of the data collected, it was concluded that the methods of replacing muco-supported prostheses with implant supported fixed prostheses were efficient at maintaining the original lip design. The wax try-in was capable of predicting the future lip design and the prosthetic compensation of the final prosthesis. More studies are required to consolidate these data.

AB - As of 2015, 98% of U.S. states require preparticipation exams (PPE) before participating in scholastic sports. Despite widespread availability of a PPE monograph endorsed by six medical societies, a lack of uniformity exists regarding implementation of the PPE among Rhode Island health care providers (HCPs). Consequently, significant variability exists regarding how comprehensive a history and physical exam screening is conducted for adolescent athletes looking for sports participation clearance. The purpose of this document is to: 1) establish a uniform screening process in Rhode Island for the PPE utilizing a peer-reviewed history and physical exam; 2) familiarize HCPs with the 2010 PPE monograph, with emphasis on the cardiovascular and musculoskeletal (MSK) systems; 3) encourage HCPs to treat the PPE as a separate entity from the annual wellness visit; 4) engage HCPs and sports medicine providers in Rhode Island to improve the quality and process of evaluating adolescent athletes for sports participation.

AB - Meniscal injury is a common cause for presentation to the emergency department or primary care physician's office. Meniscal injuries can be the result of a forceful, twisting event in a young athlete's knee or it can insidiously present in the older patient. Many patients with meniscal pathology appropriately undergo conservative management with a primary care physician while some may need referral to an orthopedist for operative intervention. Arthroscopic surgery to address the menisci is the most frequently performed procedure on the knee and one of the most regularly performed surgeries in orthopedic surgery.1 The purpose of this paper is to help elucidate the diagnosis and management of meniscal pathology resulting in knee pain.

It is increasingly recognized in athletes as a source of groin pain and is often associated with other pathology. A comprehensive approach to the physical exam and a strong understanding of hip and pelvic anatomy are critical in making the appropriate diagnosis. Various management options are available. We review the basic anatomy, patholophysiology, diagnostic approach and treatment of athletic pubalgia as well as discuss associated conditions such as femoroacetabular impingement.

AB - OBJECTIVES: To investigate the effect of different crystal- loid solutions on clinical outcomes in critically-ill patients with acute pancreatitis (AP). METHODS: We conducted a retrospective study of patients with AP admitted to the ICU using the Multiparameter Intelligent Monitoring in Intensive Care III (MIMIC III) database. We investigated the effect of fluid type; lactated ringer's (LR) vs. isotonic saline (IS) on hospital mortality rates, and ICU length of stay (LOS). RESULTS: Hospital mortality of the 198 included patients was 12%. For fluid type, 32.9% were resuscitated with LR vs. 67.1% with IS. Hospital mortality was lower in the LR group (5.8%) vs. 14.9% for IS group, odds ratio of 3.10 [P=0.041]. This effect was still observed after adjusting for confounders. However, ICU LOS was longer in LR compared to IS group; 6.2+/-6.9 vs. 4.2+/-4.49 days respectively [P= 0.020]. CONCLUSION: The type of fluid used for resuscitation in AP may affect the outcome. LR may have survival benefit over IS in critically-ill patients with AP. [Full article available at http://rimed.org/rimedicaljournal-2016-10.asp]. PMID- 27706279 TI - A Five-Year Evolution of a Student-led Elective on Health Disparities at The Alpert Medical School. AB - BACKGROUND AND OBJECTIVE: Medical students are often unprepared for social challenges in caring for safety net patients. We aim to evaluate and chronicle the evolution of a pre-clinical elective alongside medical disparities curriculum. DESIGN AND METHODS: Medical students designed the course to supplement clinical training on care of vulnerable patients. From 2011-2015, there have been 80 first-year medical student participants, five cohorts of second-year course leaders, and two supporting faculty advisors for this 10-12 session evening elective. RESULTS: Students (n=67) rated the course extremely highly (ranging from 4.4-4.6 on a five-point Likert scale). Medical students reported having significantly more knowledge of underserved populations after taking the course (difference=0.72, SE=0.16, P <0.001). Career interests and attitudes toward health disparities remained strong after taking the course. CONCLUSIONS: This student-created elective equipped participants with improved knowledge in caring for underserved patients and contributed to the incorporation of health disparities in medical curriculum.

AB - "The goal of community health teams is to develop and implement care models that integrate clinical and community health promotion and preventive services for patients." -Association of State and Territorial Health Officials (ASTHO)1 Eleven community health teams (CHTs) operate in various geographies within Rhode Island. Physicians and payers refer their highest-risk patients to CHTs that serve as community extenders. Community health workers and others work to link referred individuals to primary care and work to address the other determinants affecting their health, such as safe housing. Since much of health is driven by factors outside of the healthcare setting, CHTs compliment the work of physicians within the office environment. Transforming practices and addressing both the physical and behavioral needs of patients simultaneously is key to CHT success. This article attempts to quantify the expanding need for CHTs within Rhode Island and describes ways in which CHTs as a practice transformation resource may be leveraged by providers.

AB - Since the first diacylglycerol acyltransferase (DGAT) gene was characterized in plants, a number of studies have focused on understanding the role of DGAT activity in plant triacylglycerol (TAG) biosynthesis. DGAT enzyme is essential in controlling TAGs synthesis and is encoded by different genes. DGAT1 and DGAT2 are the two major types of DGATs and have been well characterized in many plants. On the other hand, the DGAT3 and WS/DGAT have received less attention. In this study, we present the first general view of the presence of putative DGAT3 and WS/DGAT in several plant species and report on the diversity and evolution of these genes and its relationships with the two main DGAT genes (DGAT1 and DGAT2). According to our analyses DGAT1, DGAT2, DGAT3 and WS/DGAT are very divergent genes and may have distinct origin in plants. They also present divergent expression patterns in different organs and tissues. The maintenance of several types of genes encoding DGAT enzymes in plants demonstrates the importance of DGAT activity for TAG biosynthesis. Evolutionary history studies of DGATs coupled with their expression patterns help us to decipher their functional role in plants, helping to drive future biotechnological studies. PMID- 27706371 TI - The effects of old and recent migration waves in the distribution of HBB*S globin gene haplotypes. AB - Sickle cell hemoglobin is the result of a mutation at the sixth amino acid position of the beta (beta) globin chain. The HBB*S gene is in linkage disequilibrium with five main haplotypes in the beta-globin-like gene cluster named according to their ethnic and geographic origins: Bantu (CAR), Benin (BEN), Senegal (SEN), Cameroon (CAM) and Arabian-Indian (ARAB). These haplotypes demonstrated that the sickle cell mutation arose independently at least five times in human history. The distribution of betaS haplotypes among Brazilian populations showed a predominance of the CAR haplotype. American populations were clustered in two groups defined by CAR or BEN haplotype frequencies. This scenario is compatible with historical records about the slave trade in the Americas. When all world populations where the sickle cell gene occurs were analyzed, three clusters were disclosed based on CAR, BEN or ARAB haplotype predominance. These patterns may change in the next decades due to recent migrations waves. Since these haplotypes show different clinical characteristics, these recent migrations events raise the necessity to develop optimized public health programs for sickle cell disease screening and management. PMID- 27706372 TI - Cessation of dangerousness status: an analysis of 224 reports from the Instituto de Pericias Heitor Carrilho, Rio de Janeiro, Brazil. AB - Objectives:: To evaluate factors related to dangerousness cessation at the end of involuntary commitment based on an analysis of expert reports. In light of the current legal requirement of dangerousness cessation as a pre-requisite for prison or internment release of individuals subjected to the safety measure, we sought elements to reflect on the practice of expert examiners in charge of making this decision. Methods:: The authors revised 224 expert psychiatric dangerousness cessation reports released 2011 through 2014 and collected data for a statistical analysis. Results:: The following variables were associated with positive risk cessation assessments: no inadequate behavior (according to the assistant professionals), no productive psychotic symptoms, no negative symptoms, presence of insight, presence of a support network, and no psychoactive substance abuse. The following variables were associated with negative dangerousness cessation decisions: early onset of malfunction, lack of insight, negative attitudes, active signs of major mental illness, presence of impulsiveness, poor response to treatment, presence of plans lacking feasibility, exposure to destabilizing factors, lack of personal support, and presence of stress. Conclusions:: In this study we were able to identify factors associated with dangerousness in a sample of expert reports. The knowledge of factors linked to a higher risk of recidivism in illegal activities or violent behavior is crucial for decision-making regarding the release of offenders after their legally established period of involuntary commitment. PMID- 27706373 TI - Victimization, perception of insecurity, and changes in daily routines in Mexico. AB - OBJECTIVE: To analyze the relationships between victimization, perception of insecurity, and changes in routines. METHODS: The 8,170 subjects of both sexes (49.9% women and 50.1% men) aged between 12 and 60 years, selected from a proportional stratified sampling, participated in this study. The measuring instrument was an adaptation of the National Survey on Victimization and Perception of Public Security. Chi-square tests were performed. RESULTS: The results show significant differences on victimization and sex regarding perception of insecurity, restrictions on everyday activities, and protection measures. 13.1% of those interviewed claimed to have been victims of a crime in the past 12 months. 52.7% of women considered their municipality as unsafe or very unsafe. In the case of men, this percentage was 58.2%. Female victims reported significant restrictions in everyday activities when compared to non victims. In relation to men, the percentage of victims with a high restriction of activities was higher in male victims than non-victims. In the group of victimized women, the segment of women who opted for increased measures of protection against crime was larger than expected, while those of non-victims who took less protective measures was lower than expected. These same results were observed in the group of men. CONCLUSIONS: The experience of victimization implies a greater perception of insecurity. However, the climate of insecurity is widespread in a large number of citizens. Gender differences in a high-crime environment show the importance of investigating in depth the roles of both genders in the perception of insecurity and changes in routines. OBJETIVO: Analizar las relaciones existentes entre victimizacion, percepcion de inseguridad y cambios en las rutinas. METODOS: Participaron en este estudio 8,170 sujetos de ambos sexos (49.9% mujeres y 50.1% hombres) de entre 12 y 60 anos, seleccionados a partir de un muestro estratificado proporcional. El instrumento de medida fue una adaptacion de la Encuesta Nacional de Victimizacion y Seguridad Publica. Se realizaron pruebas Chi-cuadrado. RESULTADOS: Los resultados evidencian diferencias significativas en cuanto a victimizacion y sexo con respecto a percepcion de inseguridad, restricciones de actividades cotidianas y medidas de proteccion. Un 13.1% de las personas entrevistadas afirmaron haber sido victimas de un delito en los ultimos doce meses. El 52.7% de las mujeres consideraron su municipio como inseguro o muy inseguro. En el caso de los hombres, este porcentaje fue de 58.2%. Las mujeres victimas senalaron restricciones en la vida cotidiana significativas en comparacion con las no victimas. Con relacion a los hombres, el porcentaje de victimas con un alta restriccion de actividades fue mayor en los hombres victimas que en los hombres no victimas. En el grupo de mujeres victimizadas, el segmento de mujeres que optaron por mayores medidas de proteccion frente a la delincuencia fue mayor de lo esperado, mientras que las mujeres no victimas que asumieron menores medidas de proteccion fue menor de lo esperado. Estos mismos resultados se observaron en el grupo de los hombres. CONCLUSIONES: La experiencia de victimizacion lleva implicita una mayor percepcion de inseguridad. Sin embargo, el clima de inseguridad se encuentra diseminado en gran cantidad de la ciudadanos. Las diferencias de genero en un clima de alta criminalidad muestran la importancia de investigar a profundidad los roles de ambos sexos en la percepcion de inseguridad y los cambios en las rutinas. PMID- 27706374 TI - Portuguese version of the EUROPEP questionnaire: contributions to the psychometric validation. AB - OBJECTIVE: To assess the construct validity and reliability of the Portuguese version of the European Task Force on Patient Evaluation of General Practice Care questionnaire. METHODS: We applied the Portuguese version of the European Task Force on Patient Evaluation of General Practice Care to 392 users of 20 Family Health Units from the North of Portugal. The validity of the construct was evaluated by exploratory factor analysis, with the Principal Axis Factoring method, by orthogonal rotation (varimax procedure), by the Kaiser normalization criteria (eigenvalue >= 1). The factorability of the data matrix was verified by the Kaiser-Meyer-Olkin and Bartlett's sphericity test. We estimated the reliability by the indicator of internal consistency Cronbach's alpha. To analyze the correlations between satisfaction and loyalty, we used the Pearson correlations. The predictor effect of satisfaction on loyalty was analyzed by simple linear regression. RESULTS: Satisfaction presented five robust and well individualized dimensions - medical care, nursing care, clinical secretariat services, accessibility, and organization of services - with alpha values between 0.86 and 0.97, good levels of internal consistency. The loyalty showed alpha value of 0.72, considered a reasonable internal consistency. The satisfaction was predictive of loyalty. CONCLUSIONS: The Portuguese European Task Force on Patient Evaluation of General Practice Care questionnaire is a robust and reliable instrument to measure the satisfaction and loyalty of users of the Family Health Units. OBJETIVO: Avaliar a validade de construto e fiabilidade da versao portuguesa do questionario European Task Force on Patient Evaluation of General Practice Care. METODOS: Foi aplicada a versao portuguesa do European Task Force on Patient Evaluation of General Practice Care a 392 utentes de 20 Unidades de Saude Familiar do norte de Portugal. A validade do construto foi avaliada por analise fatorial exploratoria, metodo Factoracao de Eixo Principal, por meio da rotacao ortogonal (procedimento varimax), pelo criterio de normalizacao de Kaiser (valor proprio >= 1). A fatoriabilidade da matriz dos dados foi verificada por meio do Kaiser-Meyer-Olkin e do teste de esfericidade de Bartlett. A fiabilidade foi estimada pelo indicador de consistencia interna alfa de Cronbach. Para analisar as correlacoes entre a satisfacao e a lealdade, utilizou-se as correlacoes de Pearson.

RESULTADOS: A satisfacao apresentou cinco dimensoes robustas e bem individualizadas - cuidados medicos, cuidados de enfermagem, servicos de secretariado clinico, acessibilidade e organizacao dos servicos - com valores de alfa entre 0,86 e 0,97, bons niveis de consistencia interna. A lealdade apresentou valor de alfa de 0,72, considerada consistencia interna razoavel. A satisfacao foi preditora da lealdade. CONCLUSOES: O questionario European Task Force on Patient Evaluation of General Practice Care portugues e um instrumento robusto e fiavel para medir a satisfacao e lealdade dos utentes das Unidades de Saude Familiar. PMID- 27706375 TI - Mortality and potential years of life lost by road traffic injuries in Brazil, 2013. AB - OBJECTIVE: To estimate the potential years of life lost by road traffic injuries three years after the beginning of the Decade of Action for Traffic Safety. METHODS: We analyzed the data of the Sistema de Informacoes sobre Mortalidade (SIM - Mortality Information System) related to road traffic injuries, in 2013. We estimated the crude and standardized mortality rates for Brazil and geographic regions. We calculated, for the Country, the proportional mortality according to age groups, education level, race/skin color, and type or quality of the victim while user of the public highway. We estimated the potential years of life lost according to sex. RESULTS: The mortality rate in 2013 was of 21.0 deaths per 100,000 inhabitants for the Country. The Midwest region presented the highest rate (29.9 deaths per 100,000 inhabitants). Most of the deaths by road traffic injuries took place with males (34.9 deaths per 100,000 males). More than half of the people who have died because of road traffic injuries were of black race/skin color, young adults (24.2%), individuals with low schooling (24.0%), and motorcyclists (28.5%). The mortality rate in the triennium 2011-2013 decreased 4.1%, but increased among motorcyclists. Across the Country, more than a million of potential years of life were lost, in 2013, because of road traffic injuries, especially in the age group of 20 to 29 years. CONCLUSIONS: The impact of the high mortality rate is of over a million of potential years of life lost by road traffic injuries, especially among adults in productive age (early mortality), in only one year, representing extreme social cost arising from a cause of death that could be prevented. Despite the reduction of mortality by road traffic injuries from 2011 to 2013, the mortality rates increased among motorcyclists. OBJETIVO: Estimar os anos potenciais de vida perdidos por acidente de transporte terrestre apos tres anos do inicio da Decada de Acao pela Seguranca no Transito. METODOS: Foram analisados os dados do Sistema de Informacoes sobre Mortalidade correspondentes aos acidentes de transporte terrestre, em 2013. Foram calculadas as taxas de mortalidade bruta e padronizada para o Brasil e regioes geograficas. Foi calculada, para o Pais, a mortalidade proporcional segundo faixas etarias, escolaridade, raca/cor da pele e tipo ou qualidade da vitima enquanto usuaria da via publica. Foram estimados os anos potenciais de vida perdidos segundo sexo. RESULTADOS: A taxa de mortalidade, em 2013, foi de 21,0 obitos por 100 mil habitantes para o Pais. A regiao Centro-Oeste apresentou a taxa mais elevada (29,9 obitos por 100 mil habitantes). A maioria dos obitos por acidentes de transporte terrestre foi observada no sexo masculino (34,9 obitos por 100 mil homens). Mais da metade das pessoas que faleceram em decorrencia de acidentes de transporte terrestre eram da raca/cor da pele negra, adultos jovens (24,2%), individuos com baixa escolaridade (24,0%) e motociclistas (28,5%). A taxa de mortalidade, no trienio 2011 a 2013, apresentou reducao de 4,1%, mas aumentou entre os motociclistas. Em todo o Pais, mais de um milhao de anos potenciais de vida foram perdidos, em 2013, devido aos acidentes de transporte terrestre, especialmente na faixa etaria de 20 a 29 anos. CONCLUSOES: O impacto da alta taxa de mortalidade e de mais de um milhao de anos potenciais de vida perdidos por acidentes de transporte terrestre, principalmente entre adultos em idade produtiva (mortalidade precoce), em apenas um ano, representando extremo custo social decorrente de uma causa de obito que poderia ser prevenida. Apesar da reducao da mortalidade por acidentes de transporte terrestre de 2011 a 2013, as taxas de mortalidade aumentaram entre os motociclistas. PMID- 27706376 TI - On triatomines, cockroaches and haemolymphagy under laboratory conditions: new discoveries. AB - For a long time, haematophagy was considered an obligate condition for triatomines (Hemiptera: Reduviidae) to complete their life cycle. Today, the ability to use haemolymphagy is suggested to represent an important survival strategy for some species, especially those in genus Belminus. As Eratyrus mucronatus and Triatoma boliviana are found with cockroaches in the Blaberinae subfamily in Bolivia, their developmental cycle from egg to adult under a "cockroach diet" was studied. The results suggested that having only cockroach haemolymph as a food source compromised development cycle completion in both species. Compared to a "mouse diet", the cockroach diet increased: (i) the mortality at each nymphal instar; (ii) the number of feedings needed to molt; (iii) the volume of the maximum food intake; and (iv) the time needed to molt. In conclusion, haemolymph could effectively support survival in the field in both species. Nevertheless, under laboratory conditions, the use of haemolymphagy as a survival strategy in the first developmental stages of these species was not supported, as their mortality was very high. Finally, when Triatoma infestans, Rhodnius stali and Panstrongylus rufotuberculatus species were reared on a cockroach diet under similar conditions, all died rather than feeding on cockroaches. These results are discussed in the context of the ecology of each species. PMID- 27706377 TI - Molecular detection of flaviviruses and alphaviruses in mosquitoes (Diptera: Culicidae) from coastal ecosystems in the Colombian Caribbean. AB - Arboviruses belonging to the genera Flavivirus and Alphavirus were detected in mosquitoes in a rural area of San Bernardo del Viento (Cordoba, Colombia). A total of 22,180 mosquitoes were collected, sorted into 2,102 pools, and tested by generic/nested reverse transcription-polymerase chain reaction. Venezuelan equine encephalitis virus, dengue virus, West Nile virus, St. Louis encephalitis virus, yellow fever virus, and Culex flavivirus were detected and identified by sequencing. The detection of arboviral pathogens in this zone represents possible circulation and indicates a human health risk, demonstrating the importance of virological surveillance activities. PMID- 27706378 TI - The involvement of endothelial mediators in leprosy. AB - Leprosy is a chronic infectious disease that requires better understanding since it continues to be a significant health problem in many parts of the world. Leprosy reactions are acute inflammatory episodes regarded as the central etiology of nerve damage in the disease. The activation of endothelium is a relevant phenomenon to be investigated in leprosy reactions. The present study evaluated the expression of endothelial factors in skin lesions and serum samples of leprosy patients. Immunohistochemical analysis of skin samples and serum measurements of VCAM-1, VEGF, tissue factor and thrombomodulin were performed in 77 leprosy patients and 12 controls. We observed significant increase of VCAM-1 circulating levels in non-reactional leprosy (p = 0.0009). The immunostaining of VEGF and tissue factor was higher in endothelium of non-reactional leprosy (p = 0.02 for both) than healthy controls. Patients with type 1 reaction presented increased thrombomodulin serum levels, compared with non-reactional leprosy (p = 0.02). In type 2 reaction, no significant modifications were observed for the endothelial factors investigated. The anti-inflammatory and antimicrobial activities of the endotfhelial factors may play key-roles in the pathogenesis of leprosy and should be enrolled in studies focusing on alternative targets to improve the management of leprosy and its reactions. PMID- 27706379 TI - Distribution and association between environmental and clinical isolates of Cryptococcus neoformans in Bogota-Colombia, 2012-2015. AB - The propagules of the fungal species Cryptococcus neoformans and C. gattii, whose varieties are distributed world wide, are the primary cause of cryptococcosis, a life threatening disease. The study of environmental and clinical isolates of Cryptococcosis is an important contribution to the epidemiology and ecology of the fungus. The aim of this work was to determine the presence of C. neoformans and C. gattii in the environment in Bogota, Colombia's capital city and to establish the relation between clinical and environmental isolates in the period 2012-2015. From a total of 4.116 environmental samples collected between October 2012 - March 2014, 35 were positive for C. neoformans var. grubii. From 55 cryptococcosis cases reported in Bogota during 2012-2015, 49 isolates were recovered. From those, 94% were identified as C. neoformans var. grubii molecular type VNI; 4% as VNII and 1,2% as C. neoformans var neoformans VNIV. The 84 detected clinical and environmental isolates studied had a similarity between 49 100% according with molecular typing. The correlation between environmental and clinical samples confirms the hypothesis that patients acquire the disease from environmental exposure to the fungal propagules. PMID- 27706380 TI - Symbiont modulates expression of specific gene categories in Angomonas deanei. AB - Trypanosomatids are parasites that cause disease in humans, animals, and plants. Most are non-pathogenic and some harbor a symbiotic bacterium. Endosymbiosis is part of the evolutionary process of vital cell functions such as respiration and photosynthesis. Angomonas deanei is an example of a symbiont-containing trypanosomatid. In this paper, we sought to investigate how symbionts influence host cells by characterising and comparing the transcriptomes of the symbiont containing A. deanei (wild type) and the symbiont-free aposymbiotic strains. The comparison revealed that the presence of the symbiont modulates several differentially expressed genes. Empirical analysis of differential gene expression showed that 216 of the 7625 modulated genes were significantly changed. Finally, gene set enrichment analysis revealed that the largest categories of genes that downregulated in the absence of the symbiont were those involved in oxidation-reduction process, ATP hydrolysis coupled proton transport and glycolysis. In contrast, among the upregulated gene categories were those involved in proteolysis, microtubule-based movement, and cellular metabolic process. Our results provide valuable information for dissecting the mechanism of endosymbiosis in A. deanei. PMID- 27706381 TI - Culture media profoundly affect Candida albicans and Candida tropicalis growth, adhesion and biofilm development. AB - As there are sparse data on the impact of growth media on the phenomenon of biofilm development for Candida we evaluated the efficacy of three culture media on growth, adhesion and biofilm formation of two pathogenic yeasts, Candida albicans and Candida tropicalis. The planktonic phase yeast growth, either as monocultures or mixed cultures, in sabouraud dextrose broth (SDB), yeast nitrogen base (YNB), and RPMI 1640 was compared, and adhesion as well as biofilm formation were monitored using MTT and crystal violet (CV) assays and scanning electron microscopy. Planktonic cells of C. albicans, C. tropicalis and their 1:1 co culture showed maximal growth in SDB. C. albicans/C. tropicalis adhesion was significantly facilitated in RPMI 1640 although the YNB elicited the maximum growth for C. tropicalis. Similarly, the biofilm growth was uniformly higher for both species in RPMI 1640, and C. tropicalis was the slower biofilm former in all three media. Scanning electron microscopy images tended to confirm the results of MTT and CV assay. Taken together, our data indicate that researchers should pay heed to the choice of laboratory culture media when comparing relative planktonic/biofilm growth of Candida. There is also a need for standardisation of biofilm development media so as to facilitate cross comparisons between laboratories. PMID- 27706382 TI - First detection of natural infection of Aedes aegypti with Zika virus in Brazil and throughout South America. AB - Zika virus (ZIKV) has caused a major epidemic in Brazil and several other American countries. ZIKV is an arbovirus whose natural vectors during epidemics have been poorly determined. In this study, 1,683 mosquitoes collected in the vicinity of ZIKV suspected cases in Rio de Janeiro, Brazil, from June 2015 to May 2016 were screened for natural infection by using molecular methods. Three pools of Aedes aegypti were found with the ZIKV genome, one of which had only one male. This finding supports the occurrence of vertical and/or venereal transmission of ZIKV in Ae. aegypti in nature. None of the examined Ae. albopictus and Culex quinquefasciatus was positive. This is the first report of natural infection by ZIKV in mosquitoes in Brazil and other South American countries. So far, Ae. aegypti is the only confirmed vector of ZIKV during the ongoing Pan-American epidemics. PMID- 27706383 TI - Impact of functional determinants on 5.5-year mortality in Amazon riparian elderly. AB - Objective To ascertain whether modifiable physical performance-based measurements predicted 5.5-year mortality in a riparian elderly cohort in the Amazon rainforest region. Methods A longitudinal study evaluating the impact of functional determinants on 5.5-year mortality in a riparian elderly cohort from Maues City in the state of Amazonas, Brazil, was performed. The study was a follow-up of a previous observational investigation that evaluated various fitness tests in 630 Amazonian riparian elderly (291 males and 339 females) aged 72.3 +/- 8.0 (60-99) years old. The cohort was selected for its adverse environmental conditions, which increased the risk of falls yet required maintenance of good physical condition for carrying out relatively rigorous daily activities, and restricted access to specialized health services. Official death records were obtained from the Maues Municipal Health Department. Results A total of 80 study participants (12.7%) died over the 5.5-year study period. Kaplan Meier regression analysis showed significant association between Timed Up and Go (TUG) test scores >= 14 seconds and mortality risk, independent of sex, age, and other health variables. Conclusions The study results suggest that the TUG test can be used as an indicator for initiating therapeutic and preventive actions, including conducting exercises or physical activities adapted to the health and functional conditions of the elderly, by identifying elderly people with a higher relative risk of mortality. PMID- 27706384 TI - [The debate on regulating biotechnology drugs: Colombia in the international context]. AB - In September 2014, Colombia issued standards for the evaluation of biological drugs within the framework of the marketing authorization process. The Colombian approach explicitly includes a fast track for evaluating competing biologicals, which caused great national and international controversy. This article explains the context that justifies the need for this fast-track approach, critically analyzes comparability as a paradigm for the evaluation of biogenerics, and shows that Colombia's position is not isolated and is based on global regulatory trends. PMID- 27706385 TI - Innovative in vitro methodologies for establishing therapeutic equivalence. AB - To improve the quality of pharmaceutical products in their markets, several Latin American countries have begun to require that new generic products demonstrate bioequivalence against innovator or reference products. However, given the number of products involved, it is not feasible to rely on clinical studies to comply with this requirement. Instead, it makes sense to adopt or develop strategies that are appropriate to the characteristics of the region. To streamline drug development and accelerate patients' access to quality drug products, 15 years ago the United States Food and Drug Administration (FDA) decided to grant exemptions from clinical bioequivalence studies (i.e., biowaivers) for certain types of drug products based on the Biopharmaceutics Classification System (BCS). Biowaivers can significantly reduce development time and cost and can also prevent unnecessary human exposure to potentially dangerous drugs while providing a robust, consistent standard for therapeutic equivalence of generic drug products. In addition, the limited success of translating in vitro dissolution data into in vivo performance can be enhanced using innovative tools such as the in vitro dissolution and absorption systems (IDAS). By integrating in vitro dissolution and permeability tests, these systems can provide useful insights for formulation development. A thorough assessment of the potential of in vitro techniques, along with formalization of their use through regulatory science initiatives when appropriate, may lead to cost-effective tools to help address some of the quality and regulatory challenges faced in the Latin American and Caribbean region. PMID- 27706386 TI - [Retrospective eco-epidemiology as a tool for the surveillance of leishmaniasis in Misiones, Argentina, 1920-2014]. AB - A retrospective analytical method is presented, based on theoretical eco epidemiology, applied on a subnational spatial scale. This method was used here to describe scenarios for the transmission of leishmaniasis in the Argentine province of Misiones- bordering Brazil and Paraguay-and formed the basis for recommendations for surveillance and control appropriate to the subnational scale. An exhaustive search of the literature on leishmaniasis in the province was carried out. Three scenarios for the transmission of cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) were found, corresponding to three periods: from 1920 to 1997, during which the transmission of CL distributed over time and space was confirmed; 1998 to 2005, during which there were focal outbreaks of CL; and 2006 to 2014, during which outbreaks were also reported and the geographical dispersion of VL was documented. To describe the risk scenarios and the anthropic processes that produce them, the results were summarized and integrated into the social, historical, and bio-ecological context of each period. Surveillance and control recommendations are based on the territory studied. They include establishing active surveillance to monitor possible rising trends in parasitic and vector circulation, conducting studies of any focal outbreak in order to confirm indigenous transmission and severity. Also, it should be a legal requirement for persons responsible for projects that alter the environment to adopt additional control measures, such as studies assessing transmission risk, risk mitigation, early detection, and timely case management. PMID- 27706387 TI - Oxacillin disk diffusion testing for the prediction of penicillin resistance in Streptococcus pneumoniae. AB - Objective To 1) describe the correlation between the zones of inhibition in 1-ug oxacillin disk diffusion (ODD) tests and penicillin and ceftriaxone minimum inhibitory concentrations (MICs) of meningeal and non-meningeal strains of Streptococcus pneumoniae and 2) evaluate the usefulness of the ODD test as a predictor of susceptibility to penicillin in S. pneumoniae and as a quick and cost-effective method easily implemented in a routine clinical laboratory setting. Methods S. pneumoniae isolates from healthy nasopharyngeal carriers less than 2 years old, obtained in a multicentric cross-sectional study conducted in various Peruvian hospitals and health centers from 2007 to 2009, were analyzed. Using Clinical and Laboratory Standards Institute (CLSI) breakpoints, the correlation between the zones of inhibition of the ODD test and the MICs of penicillin and ceftriaxone was determined. Results Of the 571 S. pneumoniae isolates, 314 (55%) showed resistance to penicillin (MIC >= 0.12 ug/mL) and 124 (21.7%) showed resistance to ceftriaxone (MIC >= 1 ug/mL). Comparison of the ODD test zones of inhibition and the penicillin MICs, using the CLSI meningeal breakpoints, showed good correlation (Cohen's kappa coefficient = 0.8239). Conclusions There was good correlation between ODD zones of inhibition and penicillin meningeal breakpoints but weak correlation between the ODD results and non-meningeal breakpoints for both penicillin and ceftriaxone. Therefore, the ODD test appears to be a useful tool for predicting penicillin resistance in cases of meningeal strains of S. pneumoniae, particularly in low- and middle- income countries, where MIC determination is not routinely available. PMID- 27706388 TI - [Emergence of CMY-2-type plasmid-mediated AmpC beta-lactamase in Shigella sonnei and Salmonella spp. in Costa Rica, 2003-2015]. AB - Plasmid-mediated AmpC are enzymes belonging to the group of beta-lactamases and encoded by bla AmpC genes. Of these enzymes, those known as type CMY-2 are the most frequently reported worldwide. Detection of enterobacteria that produce CMY 2-type plasmid-mediated AmpC is clinically important since the use of beta-lactam antibiotics can result in treatment failure. It is also important from a public health standpoint owing to the capacity for conjugative plasmid transfer to other enterobacteria, both within the community and in nosocomial environments. Thus, bacteria of this kind are considered to have clear epidemic potential. To investigate the circulation of this resistance mechanism among Salmonella and Shigella isolates in Costa Rica, from January 2003 to May 2015 we carried out a retrospective review of the data contained in the laboratory surveillance databases of the National Reference Bacteriology Center (CNRB) of the Costa Rican Nutrition and Health Research Institute (Inciensa). Over this period, 4363 Shigella isolates and 1785 Salmonella isolates were examined. Among them, 15 Shigella sonnei isolates and nine Salmonella isolates (four from human clinical specimens and five of avian origin) displayed a phenotype suspected of carrying plasmid-mediated AmpC. Polymerase chain reaction confirmed that all these isolates belong to type CMY-2. In light of these results, we recommend that the microbiology laboratories in the national network continue to conduct surveillance and confirm any suspicious isolates using phenotypic and molecular methods. This is particularly relevant when dealing with bacterial isolates from extraintestinal infections so as to prevent treatment failure. PMID- 27706389 TI - Agriculture, food, and nutrition interventions that facilitate sustainable food production and impact health: an overview of systematic reviews. AB - Objectives To identify the agriculture, food, and nutrition security interventions that facilitate sustainable food production and have a positive impact on health. Methods Systematic review methods were used to synthesize evidence from multiple systematic reviews and economic evaluations through a comprehensive search of 17 databases and 10 websites. The search employed a pre defined protocol with clear inclusion criteria. Both grey and peer-reviewed literature published in English, Spanish, and Portuguese between 1 January 1997 and November 2013 were included. To classify as "sustainable," interventions needed to aim to positively impact at least two dimensions of the integrated framework for sustainable development and include measures of health impact. Results Fifteen systematic reviews and seven economic evaluations met the inclusion criteria. All interventions had some impact on health or on risk factors for health outcomes, except those related to genetically modified foods. Impact on health inequalities was rarely measured. All interventions with economic evaluations were very cost-effective, had cost savings, or net benefits. In addition to impacting health (inclusive social development), all interventions had the potential to impact on inclusive economic development, and some, on environmental sustainability, though these effects were rarely assessed. Conclusions What is needed now is careful implementation of interventions with expected positive health impacts but with concurrent, rigorous evaluation. Possible impact on health inequalities needs to be considered and measured by future primary studies and systematic reviews, as does impact of interventions on all dimensions of sustainable development. PMID- 27706390 TI - [An assessment of fiscal space for public health in Peru]. AB - Objective To assess the fiscal space for public health in Peru so as to attain the goal of raising health spending to 6% of gross domestic product, as agreed upon by member countries of the Pan American Health Organization in 2014. Methods The main sources of fiscal space were identified by means of a thorough literature review. Technical feasibility was determined from statistics and national and international surveys and by reviewing various documents and official reports. Political feasibility was ascertained by studying policy guidelines. Results The sources showing the greatest technical and political feasibility are economic growth, a broadening of the personal income tax base, and an increase in tobacco-specific taxes. Decreasing informality in the job market and increasing contributory coverage are considered to be less politically feasible, but there is ample technical space for these measures. Conclusions There is enough fiscal space to allow for an increase in public health spending. Nevertheless, the 6% target will be reached only if the timeline is extended, tax revenues are increased, and informality in the job market is reduced. PMID- 27706391 TI - [Kidney disease in Colombia: Priority for risk management]. AB - Objective To describe the demographic and clinical manifestations of patients with chronic kidney disease (CKD), arterial hypertension, and/or diabetes mellitus, and to determine the association between the presence of these pathologies and the development of CKD. Methods Analytic and cross-sectional study. The information, with a cutoff date of 30 June 2013, comes from the integrated database of CKD and patients with hypertension and diabetes, which the Colombian payer entities provided to the national fund for high-cost diseases (Cuenta de Alto Costo). A descriptive analysis was conducted and the prevalence of CKD and stage 5 CKD was determined. Crude odds ratios (OR) were used to determine the association between CKD and age, sex, and diabetes. Results 2,599,419 records were analyzed, of which 40% corresponded to people with CKD. Overall, 74.9% of the population had hypertension and 6.4% had diabetes. The prevalence of CKD was 2.81%, with 94.3% of patients in stages 1 to 3. In patients with diabetes, the risk of presenting CKD is 1.03 (confidence interval of 95% [CI95%] 1.016-1.043). Among persons over 60 years of age, the risk of CKD is 2.15 (CI95% 2.140-2.167). Conclusions 33.4% of patients with hypertension or diabetes have not been studied to determine the presence or absence of CKD. It is a priority to implement strategies for secondary and primary prevention in order to prevent the progression of CKD and reduce the prevalence of risk factors such as hypertension and diabetes.

AB - Objective To describe the sanitary status of Brazilian blood establishments (BE) assessed by the national health surveillance system in 2013. Method In the present descriptive study, the sanitary profile of BE was assessed using the Blood Establishment Potential Risk Assessment Method (Metodo de Avaliacao de Risco Potencial de Servicos de Hemoterapia, MARPSH), developed by the National Sanitary Surveillance Agency (Anvisa). The MARPSH involves the evaluation of 471 structure and process items to produce an assessment of potential risk associated with critical control points in the blood cycle (vein-to-vein). Based on this assessment, BE are classified into five risk categories: low, medium-low, medium, medium-high, and high. The results were analyzed regarding the type of service (considering all levels, from coordinating centers to collection units), type of financing (public/private) and geographic region. Results Of the existing BE, 1 212 (60%) were assessed in 2013. Of these, 81% met >= 70% of the sanitary requirements (satisfactory status, corresponding to medium, medium-low, and low risk categories). Transfusion agencies (hospital units with the role of storing, running compatibility tests between donors and recipients, and transfusing blood components) and public establishments had the highest number of non-conformity structure and process items. Conclusion The use of the MARPSH facilitated the assessment of BE in Brazil and revealed objective opportunities for improvement. These gaps should be addressed by regulating authorities, especially in public services.

AB - Bacanga River Basin faces environmental problems related to urbanization and discharge of untreated domestic sewage, which compromise its ecosystem health. Due to the small number of studies that assessed its water quality, the present study aimed to assess the current status of this ecosystem based on the aquatic life protection index. Samples were carried out every two months, in a total of six events, in six sites along the basin, where the water samples were collected to assess physicochemical parameters and calculate the trophic state index and the index of minimum parameters for the protection of aquatic communities. The data were also compared with values determined by the resolution National Environment Council - CONAMA 357/05. Our results reveal significant changes in the water quality of Bacanga River Basin. An increase in nutrients and chlorophyll-a concentration led it to eutrophication. The surfactant values were high and put in danger the aquatic biota. Dissolved oxygen rates were below the values allowed by the resolution in most sites sampled. The current water quality is terrible for the protection of aquatic life in 61.92% of the sites sampled. PMID- 27706394 TI - Variation of age and total length in Sotalia guianensis (Van Beneden, 1864) (Cetacea, Delphinidae), on the coast of Espirito Santo state, Brazil. AB - Variations of age and total length of Sotalia guianensis from the state of Espirito Santo, Brazil, were evaluated. Specimens were found stranded. Age and total length of 44 Guiana dolphins were assessed based on tooth analysis. Age varied between 0.5 year and 33 years (mean = 8.23 years). Most specimens were between zero and 6 years old (47%). Total length varied from 119 cm to 198 cm, with mean of 172.52 cm. Asymptotic length was reached at 185 cm and approximately 5-6 years of age. Mean total length and age were higher than in other regions of the distribution range of the species. Nevertheless, more studies have to be carried out to evaluate the morphological variations in S. guianensis populations in the study area and Brazil. PMID- 27706395 TI - In vitro susceptibility of nematophagous fungi to antiparasitic drugs: interactions and implications for biological control. AB - The fast anthelmintic resistance development has shown a limited efficiency in the control of animal's endoparasitosis and has promoted research using alternative control methods. The use of chemicals in animal anthelmintic treatment, in association with nematophagous fungi used for biological control, is a strategy that has proven to be effective in reducing the nematode population density in farm animals. This study aims to verify the in vitro susceptibility of the nematophagous fungi Arthrobotrys oligospora, Duddingtonia flagrans and Paecilomyces lilacinus against the antiparasitic drugs albendazole, thiabendazole, ivermectin, levamisole and closantel by using the Minimum Inhibitory Concentration (MIC). MICs ranged between 4.0 and 0.031 ug/mL for albendazole, thiabendazole and ivermectin, between 0.937 and 0.117 ug/mL for levamisole, and between 0.625 and 0.034 ug/mL for closantel. The results showed that all antiparasitic drugs had an in vitro inhibitory effect on nematophagous fungi, which could compromise their action as agents of biological control. D. flagrans was the most susceptible species to all drugs. PMID- 27706396 TI - Wound-Healing potential of Sebastiania hispida (Mart.) Pax (Euphorbiaceae) ointment compared to low power laser in rats. AB - Impaired wound healing represents a serious complication in some pathologies and the use of plant extracts has proved to improve tissue repair. The objectives of this study were to evaluate the healing potential of the ointment of Sebastiana hispida compared with Aluminum-Gallium Indium-Phosphide Laser (InGaAlP) in surgically induced wounds in rats and to perform the phytochemical analysis. The phytochemical analysis was performed in the classic way and also by HPLC. A controlled study was developed with 80 rats (200-250 g) in which a linear excision was performed in the dorsal region after shaving, measuring 2 cm * 1 cm (epidermis and dermis) exposing the muscle fascia. The rats were randomly divided into four groups of twenty animals each. The experimental groups (n = 5) were G1 (Saline); G2 (crude methanol plant extract 2% + Carbopol Gel 98%); G3 (crude methanol plant extract 2% + lanolin/vaseline) and G4 (laser). The incision healing processes were monitored during 3, 7, 14 and until 21 days after excision. The histologic parameters evaluated were Collagen fiber types, microscopic examination and neovascularization. There was a significant increase in the deposition of collagen fibers, as evidenced by a better organized epithelial tissue, keratinized and showing greater proliferation of new blood vessels in the inflammatory phase in the group treated with both the extract and laser. The results were correlated to the phenolic derivatives found after qualitative and quantitative analysis. These compounds were considered responsible for the healing process. The topical treatment with S. hispida leaves, in the two different formulations, was more effective than the application of the laser (Ingan ALP) 660 nm in the model used. PMID- 27706397 TI - Vegetative propagation of Plukenetia polyadenia by cuttings: effects of leaf area and indole-3-butyric acid concentration. AB - The seeds of Plukenetia polyadenia have high levels of unsaturated fatty acids and are used as medicine and food for native people in the Peruvian and Brazilian Amazon. The objective of this study was to develop a method for vegetative propagation of Plukenetia polyadenia by rooting of cuttings. The experiment was laid out in a randomized complete block design with 12 treatments and 3 replications of 8 cuttings, in a 3 * 4 factorial arrangement. The factors were: 3 levels of leaf area (25, 50 and 75%) and 3 indole-3-butyric acid - IBA concentrations (9.84, 19.68 and 29.52mM) and a control without IBA. Data were submitted to analysis of variance and means were compared by Tukey test at 5% probability. Our results show that the use of cuttings with 50% of leaf area and treatment with 29.52mM of IBA induced high percentages of rooting (93%) and the best root formation. Vegetative propagation of Plukenetia polyadenia by cuttings will be used as a tool to conserve and propagate germplasm in breeding programs. PMID- 27706398 TI - Sharing regulatory data as tools for strengthening health systems in the Region of the Americas. AB - Regulatory transparency is an imperative characteristic of a reliable National Regulatory Authority. In the region of the Americas, the process of building an open government is still fragile and fragmented across various Health Regulatory Agencies (HRAs) and Regional Reference Authorities (RRAs). This study assessed the transparency status of RRAs, focusing on various medicine life-cycle documents (the Medicine Dossier, Clinical Trial Report, and Inspection Report) as tools for strengthening health systems. Based on a narrative (nonsystematic) review of RRA regulatory transparency, transparency status was classified as one of two types: public disclosure of information (intra-agency data) and data- and work-sharing (inter-agency data). The risks/benefits of public disclosure of medicine-related information were assessed, taking into account 1) the involvement and roles of multiple stakeholders (health care professionals, regulators, industry, community, and academics) and 2) the protection of commercial and personal confidential data. Inter-agency data- and work-sharing was evaluated in the context of harmonization and cooperation projects that focus on regulatory convergence. Technical and practical steps for establishing an openness directive for the pharmaceutical regulatory environment are proposed to improve and strengthen health systems in the Americas. Addressing these challenges requires leadership from entities such as the Pan American Health Organization to steer and support collaborative regional alliances that advance the development and establishment of a trustworthy regulatory environment and a sustainable public health system in the Americas, using international successful initiatives as reference and taking into account the domestic characteristics and experiences of each individual country. PMID- 27706399 TI - [Proposed model for managing drugs used for unregistered indications in Colombia]. AB - The use of drugs for unregistered indications, known as "off-label" use, is a practice that creates problems of rational use and access when other options are not available. Health systems should address this situation, particularly in connection with decisions concerning coverage, while trying to minimize health risks and clearly define the roles and responsibilities of the parties involved. Colombia's Ministry of Health and Social Protection (MinSalud), together with the National University of Colombia and national experts, developed a proposal for a model for managing drugs being used for unregistered indications (off-label) and their potential reimbursement with public resources, taking into account international practices and country characteristics. The management model is non punitive and is geared toward promoting the rational use of these drugs so that barriers to access are reduced whenever their use is supported by solid scientific evidence. The model addresses patient safeguards in the bioethical domain and the roles and responsibilities of the prescriber and government entities. PMID- 27706400 TI - [Regulation of medical devices in the Region of the Americas]. AB - Objective To describe and analyze the current status of and the challenges involved in the regulation of medical devices in the Region of the Americas and to present the results of the regional mapping exercise, progress toward the development of advanced assessment indicators, and the achievements of the Regional Working Group. Methods Creating a regional profile on the regulation of medical devices in the Americas is a priority for the Working Group. To this end a tool composed of 45 questions organized into six sections was developed and distributed among 15 countries for self-assessment (the participation rate was 100%). Based on the data received, nine basic indicators were established and an agreement was reached to develop advanced indicators for measuring the extent to which regulatory programs for medical devices were being implemented. Results Of the 15 countries, 93% have an agency in charge of regulating medical devices. An analysis of individual country performance shows wide variability, with some countries meeting all indicators and others meeting as few as 11%. The mapping also made it possible to generate information on collaborative partnerships, training, and regulation. Conclusions The results show significant heterogeneity at the regional level. Implementation of advanced indicators will help to identify areas of opportunity and strengths for the development of the regulatory profile. Although progress has been made toward strengthening regulatory programs for medical devices, remaining gaps need to be bridged through strategies and initiatives to be led by the Working Group.

AB - Objective To review, organize, and share the experience of the regulatory authorities of countries involved in a project headed by the Bolivarian Alliance for the Peoples of Americas (ALBA) for the establishment of a regulatory center (ALBAMED) and a single registry to facilitate access to essential medicines while ensuring quality, safety, and effectiveness, as well as to demonstrate how the construction of this forum for regional cooperation has benefited these authorities and their respective regulatory systems. Methods A descriptive, longitudinal, and retrospective study of ALBAMED's activities between 2009 and 2014 using published and archived materials. The level of agreement was determined by means of surveys; and joint development of standards, knowledge transfer, and the identification of best practices were assessed. Results The regulatory authorities of Bolivia, Cuba, Ecuador, Nicaragua, and Venezuela participated in the project. Twenty-five comparative assessments of the status of regulation in nine key areas were carried out. Six coordination meetings and four specialized workshops were held. More than 130 provisions and procedures were approved, having been developed specifically for the ALBAMED Regulatory Center or adopted from guidelines issued by the World Health Organization and the Pan American Health Organization. Conclusions The mapping exercise for a regulatory center and supranational registry for ALBA countries has enhanced the performance of participating authorities and strengthened drug regulatory systems through the development and selection of the standards to be applied, knowledge transfer, and the promotion of best practices. PMID- 27706402 TI - [Sanitary regulation as part of health policy in Brazil: gaps and challenges]. AB - Objective To outline and discuss the main challenges for sanitary regulation contained in the federal-level Brazilian health policy. Methods For the present qualitative study, based on the analysis of public policies, information was collected from documents and interviews. Document analysis provided a historical overview of the insertion of sanitary regulation into the Brazilian health policy between 1999 and 2009 (first decade of existence of the national health surveillance agency, Anvisa). In addition, 13 interviews were carried out with actors selected for their historical, technical, or academic role in the field. Content analysis was used to define themes emerging from the materials analyzed with a focus on the "content" category, which refers to strategic and operational guidelines of policy programs, projects, initiatives, and normative framework. Results Content analysis revealed five themes that reflect the challenges to sanitary regulation in Brazil: 1) objects under regulation treated as isolated cases; 2) a Brazilian-specific model of sanitary regulation that is different from other international models; 3) ignorance regarding the role of sanitary surveillance in health care; 4) absence of an information system; and 5) absence of performance indicators and assessment tools. Conclusions Sanitary surveillance must have a mission that is disentangled from inspection tasks to become an effective instrument of health protection. For that, an information system that brings the National Sanitary Surveillance System together toward major objectives is essential. The adoption of tools for assessment of action is also required, with the establishment of adequate indicators. PMID- 27706403 TI - Establishing a regulatory value chain model: An innovative approach to strengthening medicines regulatory systems in resource-constrained settings. AB - Medicines Regulatory Authorities (MRAs) are an essential part of national health systems and are charged with protecting and promoting public health through regulation of medicines. However, MRAs in resource-constrained settings often struggle to provide effective oversight of market entry and use of health commodities. This paper proposes a regulatory value chain model (RVCM) that policymakers and regulators can use as a conceptual framework to guide investments aimed at strengthening regulatory systems. The RVCM incorporates nine core functions of MRAs into five modules: (i) clear guidelines and requirements; (ii) control of clinical trials; (iii) market authorization of medical products; (iv) pre-market quality control; and (v) post-market activities. Application of the RVCM allows national stakeholders to identify and prioritize investments according to where they can add the most value to the regulatory process. Depending on the economy, capacity, and needs of a country, some functions can be elevated to a regional or supranational level, while others can be maintained at the national level. In contrast to a "one size fits all" approach to regulation in which each country manages the full regulatory process at the national level, the RVCM encourages leveraging the expertise and capabilities of other MRAs where shared processes strengthen regulation. This value chain approach provides a framework for policymakers to maximize investment impact while striving to reach the goal of safe, affordable, and rapidly accessible medicines for all. PMID- 27706404 TI - Regionalization as an approach to regulatory systems strengthening: a case study in CARICOM member states. AB - Improving basic capacities for regulation of medicines and health technologies through regulatory systems strengthening is particularly challenging in resource constrained settings. "Regionalization"-an approach in which countries with common histories, cultural values, languages, and economic conditions work together to establish more efficient systems-may be one answer. This report describes the Caribbean Regulatory System (CRS), a regionalization initiative being implemented in the mostly small countries of the Caribbean Community and Common Market (CARICOM). This initiative is an innovative effort to strengthen regulatory systems in the Caribbean, where capacity is limited compared to other subregions of the Americas. The initiative's concept and design includes a number of features and steps intended to enhance sustainability in resource-constrained contexts. The latter include 1) leveraging existing platforms for centralized cooperation, governance, and infrastructure; 2) strengthening regulatory capacities with the largest potential public health impact; 3) incorporating policies that promote reliance on reference authorities; 4) changing the system to encourage industry to market their products in CARICOM (e.g., using a centralized portal of entry to reduce regulatory burdens); and 5) building human resource capacity. If implemented properly, the CRS will be self-sustaining through user fees. The experience and lessons learned thus far in implementing this initiative, described in this report, can serve as a case study for the development of similar regulatory strengthening initiatives in resource constrained environments.

PMID- 27706406 TI - [Strengthening health regulation in the Americas: regulatory authorities of regional reference]. AB - Health technology regulation and quality assurance are critical to the development of national pharmaceutical policies, and implementing these actions is the responsibility of national regulatory authorities, whose level of development and maturity affect the quality, safety, and effectiveness of the products made available to the public. On the initiative of the regulatory authorities themselves, together with the Pan American Health Organization, the Region of the Americas promotes the strengthening of health regulation through an evaluation and certification process that allows for the designation of regulatory authorities of regional reference for drugs and biological products. Over the period from its implementation to the present, six authorities have been certified and one is in the process of obtaining certification. These authorities work jointly and promote dialogue and regulatory convergence, information-sharing to facilitate regulatory decision making, and regional cooperation to support the establishment of other authorities in the Region--actions having direct impact on access to effective and quality-assured health technologies. Their combined efforts have led to the recognition of this process of evaluation and certification by the World Health Organization (WHO). Among the actions resulting from the International Consultation on Regulatory Systems Strengthening, WHO recommended taking a close look at this model to assess its potential scale-up at the global level.

AB - Objective To describe the benefits obtained through South-South and triangular cooperation as a potential tool for strengthening medicine quality control in official medicines control laboratories (OMCLs) of the Region of the Americas. Methods Descriptive study of the project for strengthening drug quality control in OMCLs of the Caribbean community (CARICOM). Results Staff members of Argentina's National Administration for Drugs, Food, and Medical Technology (ANMAT) provided training to professionals from Guyana, Jamaica, Suriname, and Trinidad and Tobago. The project was funded by the Argentine Fund for South-South and Triangular Cooperation (FO.AR) and coordinated by the Pan American Health Organization (PAHO). Documents on good laboratory practice (GLP) developed by the World Health Organization (WHO) and the Pan American Network for Drug Regulatory Harmonization (PANDRH) were reviewed, and the area of physical and chemical controls was strengthened, primarily for drugs to treat tuberculosis, malaria, and HIV/AIDS, all of which are strategically important to those countries. Conclusion This type of collaboration makes it possible to share experiences, optimize resources, harmonize procedures and regulations, and strengthen human resource capacities. In addition, it is a valuable tool for reducing asymmetries in various areas among the different countries of our Region.

PMID- 27706409 TI - Regulatory convergence and harmonization: barriers to effective use and adoption of common standards. AB - Objective To evaluate 1) the level of use and adoption of eight Technical Documents (TDs) published by the Pan American Network for Drug Regulatory Harmonization (PANDRH) member states and 2) identify the hurdles that can prevent countries from successfully adopting a common standard. Methods An in-depth analysis of the incorporation of PANDRH Technical Document No. 1 ("TDNo1") recommendations in member states' national requirements was carried out. Results The results illustrate the role of PANDRH in promoting convergence/harmonization among its members. Conclusions The study results show that the rate of use of TDs varied greatly by product/area and country. Timing, TD content, and product/area, and, more importantly, national capacities, are critical determinants of the level of TD guideline adoption. While PANDRH TDs have proven instrumental for the harmonization/convergence of member states' national requirements, as shown by the level of convergence across a majority of the national requirements issued for vaccine licensing, several countries had yet to incorporate common standards due, in large part, to weak national regulatory capacities. Therefore, harmonization/convergence initiatives should include the strengthening of national regulatory capacities as part of their core strategy, which will, in turn, allow for the incorporation and deployment of common standards in all participating countries. PMID- 27706410 TI - [Strengthening the Pan American Network of Official Medicines Control Laboratories]. AB - Objective Official Medicines Control Laboratories (OMCLs) play a critical role in quality assurance. The objective of this work is to describe the actions taken by the Pan American Health Organization (PAHO) to strengthen OMCLs in the Region of the Americas. Methods A descriptive study was conducted by the External Quality Control Program (EQCP) to assess the diagnostic and overall performance of OMCLs; human resource training; measures adopted by the Pan American Network for Drug Regulatory Harmonization (PANDRH) to facilitate prequalification of OMCLs by the World Health Organization (WHO) as reference laboratories for United Nations agencies; and the technical documents developed by the Working Group on Good Laboratory Practice (WGGLP) and their level of implementation. Results The Pan American Network of OMCLs, established in 2005, is currently composed of 28 OMCLs in 23 countries. The EQCP assessed the performance of OMCLs in ten stages; 784 professionals, 313 of them from OMCLs, received training in good laboratory practice (GLP). Guidelines for external evaluation and self-evaluation were developed. Six OMCLs attained WHO prequalification and nine became regional reference laboratories. Conclusions The initiatives undertaken made it possible to strengthen the activity of the OMCLs and to train human resources. Furthermore, they provided tools for continuous improvement through external evaluation and self-evaluation. PMID- 27706411 TI - Fifty years of the European medicines regulatory network: reflections for strengthening intra-regional cooperation in the Region of the Americas. AB - This report considers how the experience of the European regulatory system might be applied to help strengthen the regulatory systems for medicines in the Region of the Americas. The work of the European Medicines Agencies (EMA) is carried out through its scientific committees, composed of members from European Economic Area countries. A robust legal framework allows EMA to coordinate resources from Member States' competent authorities, including, for example, assisting candidate countries as they prepare to join the European Union (EU). Capacity-building programs help countries adjust their regulatory systems ahead of full participation in the European medicines regulatory network. These programs facilitate adoption of common technical requirements, identify areas where action might be needed to ensure the smooth transposition of EU pharmaceutical law into national legislation, and prepare candidate countries for participation in EMA committees and the European regulatory network. The methodology of these programs could be of potential interest to the Pan American Health Organization (PAHO), the Regional Office of the World Health Organization for the Americas. Given resolutions adopted by the World Health Assembly and the PAHO Directing Council, there is a strong indication that the countries of the Region of the Americas wish to assemble a system that uses the existing regulatory capacity of some countries to strengthen local regulatory capacities in others. PMID- 27706412 TI - [Regulatory Program for Medical Devices in Cuba: experiences and current challenges]. AB - Regulatory control of medical devices in Cuba is conducted through a system based on the Regulatory Program for Medical Devices as a way to ensure the safety, efficacy, and effectiveness of these technologies, which are in use by the National Health System. This program was launched in 1992, when the Regulations for State Evaluation and Registration of Medical Devices were approved. Its successive stages and the merging of regulatory activities for drugs and medical equipment have meant progress toward stronger, more transparent strategies and greater control of industry and the National Health System. Throughout its course the Cuban program has met with challenges and difficulties that it has addressed by drawing on its own experiences. During the new period, the greatest challenges revolve around ensuring that regulatory systems incorporate scientific evaluation, risk levels, maximum rigor through the use of technical standards, and the implementation of international recommendations, together with the application of the ISO 13485 certification scheme, enhanced market monitoring, and classification of medical devices in accordance with their relevance to the country's national health policies. From the regional standpoint, the greatest challenge lies in working toward regulatory convergence. The Collaborating Centre for the Regulation of Health Technologies will support the proposed regulatory strategy and established regional priorities, in particular in connection with the implementation of actions involving medical devices. PMID- 27706413 TI - [Convergence of healthcare regulation in the Americas: history, development, and new challenges]. AB - The present article describes the changing relationship among healthcare regulatory authorities in various international settings, with special emphasis on the Americas. As other sectors, healthcare also faces the need to regulate international practices, while at the same time taking into consideration the specific realities of each country. Regulatory convergence - a movement towards technical alignment to enable the adoption of local regulatory mechanisms that take into account internationally recognized standards and principles to promote a single sanitary goal - has emerged as a means to address this challenge. Organizations that already use this tool, such as the International Conference of Drug Regulatory Authorities (ICDRA), Pan American Network for Drug Regulatory Harmonization (PANDRH), International Generic Drug Regulators Programme (IGDRP), and the International Medical Device Regulators Forum (IMDRF), among others, are currently working to gather knowledge, data, and specialists from different countries to build an international technical and scientific standard that can be used for decision-making by local regulators. This would ensure convergence of national regulations despite the need to adapt international standards to local needs, structure, and capacities. The most recent resolutions issued by the World Health Organization recognize the need to bring regulatory systems closer to the reality of national healthcare systems, and underscore the advantages of using existing local guidelines as input for cooperation with regulatory authorities.

PMID- 27706415 TI - Congenital myasthenic syndromes and myasthenia gravis are challenging diagnoses in neurological practice. PMID- 27706416 TI - Olfactory alterations in patients with multiple sclerosis. AB - Objective: To assess olfactory function using the Connecticut test and verify correlations between olfactory alteration, disease duration and the Expanded Disability Status Scale (EDSS). Methods: One hundred MS patients and 100 healthy control patients responded to a questionnaire. Those with olfactory alteration underwent a facial CT to exclude other causes. Results: Thirty-two percent of patients showed alterations, compared with 3% in the healthy control group. Patients having EDSS above 4, showed a 5.2-times increased risk of dysfunction. Patients over 38 years of age have a 2.2-times increased risk over younger patients. Conclusions: Because MS patients are likely to experience olfactory alterations, this study is a useful tool in follow-up care, although more studies are necessary to evaluate the correlations in MS evolution. PMID- 27706417 TI - Sleep disorder investigation might be considered to be mandatory in attention deficit/hyperactivity disorder guideline. AB - Objective: To determine the prevalence of obstructive sleep apnea (OSA) in children with attention deficit/hyperactive disorder (ADHD) and compare amplitude and latency of the P300 potential among children with and without OSA. Method: Sixty-one children with ADHD underwent oddball auditory attention tests for detection of P300 (ERPs) followed by an all-night polysomnography. The children were divided in two groups, those with and without OSA. Results: Significant decreased amplitude of the P300 potential was observed in children with OSA when compared with children without OSA. Conclusion: The study showed that sleep fragmentation as a result of OSA can exacerbate the attention disorder that characterizes ADHD, and highlights the importance of assessing the presence of OSA in the differential diagnosis of children with attention deficits.

PMID- 27706418 TI - Association between clinical condition and F-waves changes in the acute phase of stroke. AB - Objective: To relate F-waves with clinical and laboratory exams in the acute phase of stroke. Methods: Inclusion criteria for this cross-sectional study were: hemiplegia, absence of previous cranial trauma, myopathy, diabetes, alcoholism or other known causes of peripheral neuropathy, and normal sensory and motor conduction. The National Institutes of Health Stroke Scale (NIHSS) score, glycemia, glucosilate hemoglobin, and CPK were obtained at admission by routine blood exams. After hospital admission, the F-wave latencies and persistence were obtained from the deep peroneal nerve using symmetrical techniques. Results: Evaluation of 20 individuals - mean age 66 years, 50% male and 85% Caucasian - showed association of F-wave persistence with glycemia (r = 0.71; p < 0.001) and NIHSS categorized (NIHSS 1-7 = 65.0 x NIHSS 9-23 = 100; p = 0.004). Multivariate analysis found only association of F-wave persistence with glycemia beta = 0.59 (0.44-0.74); p < 0.001. Conclusion: The increase in the persistence of F-waves are associated with hyperglycemia in the acute phase of stroke. PMID- 27706420 TI - Analysis of the albumin level, neutrophil-lymphocyte ratio, and platelet lymphocyte ratio in Guillain-Barre syndrome. AB - The purpose of this study was to investigate the prognostic value of the pretreatment and post-treatment albumin level, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) in subtypes of Guillain-Barre syndrome (GBS). A retrospective analysis of 62 patients with GBS treated between 2011 and 2015 in Dicle University Hospital, Turkey, was carried out. The pretreatment and post treatment albumin, NLR, and PLR were documented, together with acute inflammatory demyelinating polyradiculoneuropathy (AIDP), acute motor axonal neuropathy, motor sensory axonal neuropathy, and Hughes' scores. Post-treatment albumin levels in GBS were significantly reduced, and albumin level was negatively correlated with the Hughes scores. Elevated pretreatment NLRs and PLRs were significantly associated with AIDP. There were no correlations between the Hughes scores, NLR, and PLR. The results point to a negative correlation between albumin levels and GBS disability and suggest that the NLR and PLR may be promising blood biomarkers of AIDP. PMID- 27706421 TI - Effects of crocin on brain oxidative damage and aversive memory in a 6-OHDA model of Parkinson's disease. AB - The purpose of the present study was to investigate the effect of crocin on brain oxidative damage and memory deficits in a 6-hydroxydopamine (6-OHDA) model of Parkinson's disease. Male Wistar rats were subjected to unilateral injection of 6 OHDA (16 ug) into the medial forebrain bundle and treated with crocin (30 and 60 mg/kg) for six weeks. The rats were tested for memory performance at six weeks after 6-OHDA infusion, and then were killed for the estimation of biochemical parameters. The increase in thiobarbituric acid reactive substances (TBARS) and nitrite levels in the hippocampus were observed in the 6-OHDA lesioned rats, which was accompanied by memory deficits in a passive avoidance test at the end of week 6. Moreover, treatment with crocin decreased TBARS and nitrite levels in the hippocampus, and improved aversive memory. The present study conclusively demonstrated that crocin acts as an antioxidant and anti-inflammatory agent in the hippocampus of parkinsonian rats and could improve aversive memory through its properties.

We performed a systematic literature review to evaluate the indications for anterior and posterior approaches in the management of CFD. Anterior approaches can restore cervical lordosis, and cause less postoperative pain and less wound problems. Posterior approaches are useful for direct reduction of locked facet joints and provide stronger fixation from a biomechanical point of view. Combined approaches can be used in more complex cases. Although both anterior and posterior approaches can be used interchangeably, there are some patients who may benefit from one of them over the other, as discussed in this review. Surgeons who treat cervical spine trauma should be able to perform both procedures as well as combined approaches to adequately manage CFD and improve patients' final outcomes. PMID- 27706423 TI - Aged Lewis rats exposed to low and moderate doses of rotenone are a good model for studying the process of protein aggregation and its effects upon central nervous system cell physiology. AB - Cell physiology is impaired before protein aggregation and this may be more relevant than inclusions themselves for neurodegeneration. The present study aimed to characterize an animal model to enable the analysis of the cell biology before and after protein aggregation. Ten-month-old Lewis rats were exposed either to 1 or 2 mg/kg/day of rotenone, delivered subcutaneously through mini pumps, for one month. Hyperphosphorylated TAU, alpha-synuclein, amyloid-beta peptide and protein carbonylation (indicative of oxidative stress) were evaluated in the hippocampus, substantia nigra and locus coeruleus through immunohistochemistry or western blot. It was found that 2 mg/kg/day rotenone increased amyloid-beta peptide, hyperphosphorylation of TAU and alpha-synuclein. Rotenone at 1mg/kg/day did not alter protein levels. Protein carbonylation remained unchanged. This study demonstrated that aged Lewis rats exposed to a low dose of rotenone is a useful model to study cellular processes before protein aggregation, while the higher dose makes a good model to study the effects of protein inclusions. PMID- 27706425 TI - Clinical and genetic basis of congenital myasthenic syndromes. AB - Neuromuscular junction disorders represent a wide group of neurological diseases characterized by weakness, fatigability and variable degrees of appendicular, ocular and bulbar musculature involvement. Its main group of disorders includes autoimmune conditions, such as autoimmune acquired myasthenia gravis and Lambert Eaton syndrome. However, an important group of diseases include congenital myasthenic syndromes with a genetic and sometimes hereditary basis that resemble and mimick many of the classic myasthenia neurological manifestations, but also have different presentations, which makes them a complex clinical, therapeutic and diagnostic challenge for most clinicians. We conducted a wide review of congenital myasthenic syndromes in their clinical, genetic and therapeutic aspects. PMID- 27706426 TI - Abnormal eye movements in three types of chorea. AB - Chorea is an abnormal movement characterized by a continuous flow of random muscle contractions. This phenomenon has several causes, such as infectious and degenerative processes. Chorea results from basal ganglia dysfunction. As the control of the eye movements is related to the basal ganglia, it is expected, therefore, that is altered in diseases related to chorea. Sydenham's chorea, Huntington's disease and neuroacanthocytosis are described in this review as basal ganglia illnesses that can present with abnormal eye movements. Ocular changes resulting from dysfunction of the basal ganglia are apparent in saccade tasks, slow pursuit, setting a target and anti-saccade tasks. The purpose of this article is to review the main characteristics of eye motion in these three forms of chorea. PMID- 27706427 TI - Pain characterization in Duchenne muscular dystrophy. AB - Objective: To investigate the relationship between DMD and pain. Methods: We conducted a systematic review in Medline/PubMed and BVS (virtual library in health) databases. We searched for articles that showed the terms "Muscular Dystrophy, Duchenne" and "Pain" in all fields. All studies included boys diagnosed with DMD and the occurrence/amount of pain on this population. Results: Initially, there were 175 studies. 167 articles were excluded for not meeting the inclusion criteria. The remaining eight eligible studies, involving pain assessment in DMD, were analyzed. Conclusion: Pain is a frequent problem in this population and this symptom is potentially tractable. Studies conclude that pain can directly influence the quality of life of this population. PMID- 27706428 TI - Kraepelin's description of chronic mania: a clinical picture that meets the behavioral variant frontotemporal dementia phenotype. AB - Chronic mania is an under-investigated condition and few reports have associated this disorder with an organic background. The present work examines Kraepelin's reliable description of chronic mania from a current behavioral neurology viewpoint. Kraepelin had described a cluster of symptoms that are now recognized as core manifestations of the behavioral variant frontotemporal dementia (bvFTD) clinical phenotype. We also carried out additional reviews of original manuscripts from Kraepelin's peers, in order to find any case reports that might fulfill the current diagnostic proposal for bvFTD. Even though we failed to find an ideal case, we found some scholars who seemed to agree that chronic mania should be considered a special form of dementia. The present work highlights, through historical data, the possible overlapping features between primary psychiatric disorders and neuropsychiatric symptoms secondary to neurodegenerative conditions. PMID- 27706429 TI - A multi-country, cross-sectional observational study of retinopathy of prematurity in Latin America and the Caribbean. AB - Objective To consolidate available information from the Latin American and Caribbean (LAC) region on 1) national incidence of retinopathy of prematurity (ROP) and 2) national-level government inputs on ROP (existing national policies, guidelines, programs, and financing for ROP prevention, detection, and treatment, including ROP screening) in 2014. Methods In March and April 2015, a multi country online survey was distributed to 56 medical and public health experts working on ROP in LAC countries. Respondents were instructed to provide quantitative and qualitative information representative of the national situation in 2014 for ROP incidence and national-level government inputs (existing national policies, guidelines, programs, and financing for ROP prevention, detection, and treatment, including ROP screening) in their country. Results The survey was completed in full by a total of 11 experts from 10 LAC countries (Argentina, Brazil, Colombia, Costa Rica, Cuba, Dominican Republic, El Salvador, Mexico, Nicaragua, and Panama). According to the survey results, six countries had a national policy that includes ROP prevention, detection, and treatment, with screening and treatment covered by national/federal funding. Eight countries had national guidelines for ROP. Four countries had legislation mandating eye examination of preterm infants. Most countries had Level 3 and 4 neonatal intensive care units with ROP programs in public sector health care facilities. Five countries had a data collection or monitoring system to track the number of newborn babies screened for ROP within hospital settings. On average, countries with three or four of the above-mentioned ROP elements screened 95% of eligible newborns in 2014, while those with only one or two of the ROP elements screened 35% of eligible newborns. Conclusions National government buy-in and involvement in ROP screening and treatment legislation is related to a higher proportion of eligible premature newborns being screened and treated for ROP. Further research should include more countries and assess national-level engagement with ROP, including ROP screening and treatment. PMID- 27706430 TI - ? PMID- 27706431 TI - Interventions that facilitate sustainable development by preventing toxic exposure to chemicals: an overview of systematic reviews. AB - Objective To identify interventions that 1) facilitate sustainable development by preventing toxic exposure to chemicals, including pesticides, and 2) have a positive impact on health. Methods This overview utilized systematic review methods to synthesize evidence from multiple systematic reviews and economic evaluations. A comprehensive search was conducted based on a predefined protocol, including clear inclusion criteria. To be classified as "sustainable" interventions needed to aim (explicitly or implicitly) to 1) have a positive impact on at least two key dimensions of the United Nations integrated framework for sustainable development and 2) include measures of health impact. Results Thirteen systematic reviews and two economic evaluations met the inclusion criteria. The interventions that were most likely to have a positive impact on health included 1) legislation to ban Endosulfan pesticide to prevent fatal poisonings; 2) testing of drinking water for contamination with arsenic, and dissemination of the results to households; and 3) implementation of organic farming / diet to reduce exposure to pesticides. However, the cost-effectiveness of these three interventions and their impact(s) on health inequalities is not known. Strict enforcement of interventions to reduce lead in houses with children was cost-beneficial. Education and dust control interventions performed by cleaning professionals to reduce blood lead levels in children were ineffective. Conclusions What is needed now is careful implementation of the interventions whose impacts are likely to be positive. Ineffective interventions need to be replaced with more effective and cost-effective interventions. Finally, more and better-quality research on the prevention of toxic exposure to chemicals is needed to better support policy development. PMID- 27706432 TI - [A fine line between legal and illegal oral drug repackaging]. AB - In 2009, with the implementation of the National Hospital Pharmacy Model, Mexico began regulating single-dose drugs. The repackaging of oral drugs is fundamental and critical and should be standardized by Mexican health legislation to enable quality drugs to be dispensed. Data is required on stability, compatibility, drug interactions, containers, and repackaging methods, in order to establish a new expiration date. The literature on health regulations applicable to repackaging was analyzed, revealing major conceptual imprecisions since there is no legislation in Mexico that regulates repackaging; rather, everything is carried out according to pharmacists' recommendations and criteria. The conclusion is that the regulations need to be rewritten to establish minimum single-dose oral drug criteria for dispensing hospitals-regulations that cover infrastructure, equipment, and professionals complying with good practices in oral drug repackaging. A proposal is offered to implement an official Mexican standard that regulates single-dose repackaging and unifies concepts, criteria, and means of verification, while the pharmaceutical industry would be responsible for the technology and resources for single-dose drug packaging designed for the health sector. PMID- 27706433 TI - [Overview of regulatory aspects guiding tablet scoring]. AB - Tablet scoring is a controversial but common practice used to adjust doses, facilitate drug intake, or lower the cost of drug treatment, especially in children and the elderly. The risks of tablet scoring are mainly related to inaccuracies in the resulting dose and stability problems. The aim of this article is to provide an overview of worldwide guidelines regarding tablet scoring. We found that regulatory health agencies in Mercosur countries as well as other South American countries do not have published standards addressing tablet splitting. Among the surveyed health agencies, the Food and Drug Administration (FDA) in the United States is the only one to present standards, ranging from splitting instructions to regulation of the manufacturing process. The concept of functional scoring implemented by the FDA has introduced some level of guarantee as to the ability of tablets to be split. In conclusion, technical and scientific bases are still insufficient to guide health rules on this subject, making the decision on scoring, in certain situations, random and highly risky to public health. The need for more detailed regulation is vital to ensure the safety of tablet medications. PMID- 27706434 TI - [Strategy for determining a baseline in areas of vector interruption for Chagas disease]. AB - Objectives Present a strategy to determine the baseline in endemic areas in the process of vector interruption for Chagas disease (CHD). Methods A social and environmental questionnaire and an entomological survey evaluated the physical conditions of dwellings, the inhabitants' knowledge of CHD, the entomological triatomine indicators and the statistical relationship among these variables. Results Colonization and natural infection with Trypanosoma cruzi exist in Rhodnius prolixus, the principal vector of CHD in Colombia. Colonization was related to palm-thatched houses constructed with adobe or wattle and daub. The Panstrongylus geniculatus vector was found to be colonizing. Almost 50% of the surveyed population associated the term CHD with human disease and 37%, with triatomines. Conclusions R. prolixus can be considered to be the principal vector of T. cruzi in domestic environments and the process of interruption is feasible within the prioritized municipality. New studies are needed to verify the existence of wild populations of R. prolixus that could affect future stages of the process and demonstrate whether P. geniculatus is a factor in the transmission of T. cruzi. These scenarios can be made viable by including the inhabitants throughout the process, since they have been highly sensitive in vector detection inside their houses. The study design presented here can be adapted to other endemic areas of the Region of the Americas. PMID- 27706435 TI - [Validation of a questionnaire to evaluate administrative causes of low reporting of adverse drug reactions]. AB - Objective Design and validate a survey to determine the administrative causes that can influence low reporting of adverse drug reactions. Methods The questionnaire design was based on a review of the literature and on brainstorming. The variables considered to influence reporting were professional workload and the professional perception of drug surveillance control activities. To validate the hypothesis, 60 professionals were surveyed in a convenience sample. Reliability was calculated using Cronbach's alfa and the Kuder-Richardson coefficient. Content validity was measured using the Kendall coefficient, and criterion validity, through concordance with the established criterion. Results The survey-type questionnaire was composed of 15 questions divided into two parts: general information and administrative causes of low adverse drug reactions reporting. Cronbach's alfa was 0.87, the Kuder-Richardson coefficient was 0.9033, and overall validity was 1.51, resulting from 70% concordance and a rank correlation coefficient of 0.81. Conclusions The reliability of the validated survey was acceptable to high and validity was acceptable. PMID- 27706436 TI - Health care factors associated with survival among women with breast cancer on hormone therapy in Rio de Janeiro, Brazil, 2004 - 2010. AB - Objectives To better understand the role that health care plays in breast cancer survival by investigating the effects that hormone therapy adherence and other select health care variables, adjusted for clinical and sociodemographic factors, had among a population of women in Rio de Janeiro, Brazil. Methods This was a longitudinal study based on secondary data of 5 861 women treated with hormone therapy (tamoxifen or aromatase inhibitors) at the National Cancer Institute of Brazil (INCA), from 1 January 2004 - 29 October 2010. Four different sources of data were integrated for analysis: INCA Pharmacy Sector Dispensation System; Hospital-based Cancer Registry; Integrated Hospital System and INCA Absolute System; and Mortality Information System. Analyses explored the effects of adherence to hormone therapy, disease care aspects, and sociodemographic, behavioral, and clinical variables, on the time of survival, using Kaplan-Meier and Cox proportional hazards models. Results The general survival rate was 94% in the first year after initiation of hormone therapy, and 71% in the fifth year. The Cox model indicated a higher hazard of death among women smokers, with more hospitalizations, more exams, and, among those who used, who used only aromatase inhibitors, as hormone therapy modality. The hazard was lower among women with a partner (stable relationship), a high school or college education a family history of cancer, and those who were treated by a mastologist, oncologist, and/or psychotherapist, who underwent surgery, and who adhered to hormone therapy. Conclusions The study indicated more vulnerable sub-groups and the aspects of care that provide best results, bringing new knowledge to improve assistance to this group of women. PMID- 27706437 TI - [Availability of indicators for monitoring the achievement of "Universal Health" in Latin America and the Caribbean]. AB - Objective The objective of this study was to identify the availability of health indicators for validly measuring advances in the attainment of "universal health" in Latin America and the Caribbean (LAC). Methods A systematic search was undertaken for scientific evidence and available technical and scientific documents on assessing health system performance and advances in universal health in the following phases: phase 1, mapping of indicators; phase 2, classification of indicators; and phase 3, mapping the availability of selected indicators in LAC. Results Sixty-three (63) national sources of information and eight international sources were identified. A total of 749 indicators were selected from the different databases and studies evaluated, 619 of which were related to the attainment of universal health and 130 to the burden of disease. The following indicators were identified: financial protection, 42 (6%); coverage of service delivery, 415 (55.4%); population coverage, 6 (0.8%); health determinants, 101 (14%); assessment of inequalities in health, 55 (7.3%); and estimation of burden of disease, 130 (17.3%). Finally, the availability of 141 indicators was mapped for each LAC country. Conclusions The results of this study will help establish a framework for measuring the achievements, obstacles, and rate of progress toward universal health in LAC. PMID- 27706438 TI - [Social impact of literacy in the household: analysis of the association with smoking in illiterate co-residents in Brazil]. AB - Objective To investigate the social impact of literacy on the smoking behavior of illiterate individuals who share the household with literate individuals. Method This cross-sectional study employed data from the 2008 Brazilian National Household Survey (Pesquisa Nacional por Amostra de Domicilios, PNAD). Smokers were defined as individuals reporting use of any tobacco product daily or less than daily. The literacy profiles of residents were identified. Poisson regressions adjusted for skin color, age, and maximum level of literacy in the household were performed. Four groups were analyzed: men living in rural areas, men living in urban areas, women living in rural areas, and women living in urban areas. Results For urban men, the presence of literate women only in the household was a protection factor against smoking (prevalence ratio, PR: 0.77; 95%CI: 0.71-0.82) vs. households in which all the males were illiterate. The same protective effect was found for rural men (PR: 0.79; 95%CI: 0.73-0.85). In turn, the presence of literate men only living in the same household with illiterate men did not provide protection against smoking in any case (PR: 0.93; 95%CI: 0.83 1.03 for the urban subsample; and PR: 0.99; 95%CI: 0.88-1.11 for the rural subsample). Illiterate women benefited from the presence of both literate men (PR: 0.77; 95%CI: 0.71-0.84 for the urban sample; and PR: 0.78; 95%CI: 0.69-0.89 for the rural subsample) and literate women (PR: 0.81; 95%CI: 0.72-0.92 for the urban subsample; and PR: 0.75; IC95%: 0.60-0.93 for the rural subsample). Conclusions Literate women seem to have positively affected illiterate co residents of both sexes. This result is in agreement with reports showing broad advantages of female schooling. PMID- 27706440 TI - Epistemological world awareness of healthcare faculty. AB - Objective: To understand how epistemological world awareness is expressed in the educational practices of healthcare professors. Methods: A qualitative, descriptive, exploratory, and analytical study. Data were collected through open end interviews and non-participant observation from May to December 2013, with 10 professors from a public university in southern Brazil. The adopted theoretical framework was the composition of Paulo Freire and Lee Shulman. Data were analysed according to the operative proposal of Minayo. Results: The emerging category was Epistemological world awareness of healthcare professors. Conclusions: For professors to understand and reflect on the core knowledge categories required for their practice, they must have an epistemological world awareness that allows them to perceive themselves as unfinished in relation to the world and able to transform their practice. PMID- 27706439 TI - Swimming training attenuates oxidative damage and increases enzymatic but not non enzymatic antioxidant defenses in the rat brain. AB - Although it is well known that physical training ameliorates brain oxidative function after injuries by enhancing the levels of neurotrophic factors and oxidative status, there is little evidence addressing the influence of exercise training itself on brain oxidative damage and data is conflicting. This study investigated the effect of well-established swimming training protocol on lipid peroxidation and components of antioxidant system in the rat brain. Male Wistar rats were randomized into trained (5 days/week, 8 weeks, 30 min; n=8) and non trained (n=7) groups. Forty-eight hours after the last session of exercise, animals were euthanized and the brain was collected for oxidative stress analysis. Swimming training decreased thiobarbituric acid reactive substances (TBARS) levels (P<0.05) and increased the activity of the antioxidant enzyme superoxide dismutase (SOD) (P<0.05) with no effect on brain non-enzymatic total antioxidant capacity, estimated by FRAP (ferric-reducing antioxidant power) assay (P>0.05). Moreover, the swimming training promoted metabolic adaptations, such as increased maximal workload capacity (P<0.05) and maintenance of body weight. In this context, the reduced TBARS content and increased SOD antioxidant activity induced by 8 weeks of swimming training are key factors in promoting brain resistance. In conclusion, swimming training attenuated oxidative damage and increased enzymatic antioxidant but not non-enzymatic status in the rat brain. PMID- 27706441 TI - Assessing nursing diagnoses and interventions in labour and high-risk pregnancies. AB - Objective: To evaluate the use of nursing diagnoses and interventions proposed for women in labour and high-risk pregnancies. Method: This is a descriptive, retrospective study with documentary analysis of 1000 medical records and a checklist conducted from July to September 2014, at a maternity hospital in Paraiba, Brazil. It consisted of analysing descriptive measures and comparing the relationship between nursing diagnoses and interventions using NANDA - International and the Nursing Interventions Classification. Results: The most common diagnoses in labour were acute pain (62%), fatigue (24.7%), and anxiety (22%). For high-risk pregnant women they were impaired sleep and rest (100%), risk of infection (81.8%), and anxiety (77.2%). The interventions were hand washing (80.8%) and identify and accommodate patient in the bed (78%). Conclusion: The diagnoses express needs during parturition and the psychobiological changes in high-risk pregnancy. The interventions are disconnected from the diagnoses and should therefore be reviewed and altered. PMID- 27706442 TI - Women waste pickers: living conditions, work, and health. AB - Objective: To know the elements of work, health, and living conditions of women who pick recyclable waste and are members of a waste cooperative in a town of the state of Rio Grande do Sul, Brazil. Method: This is a qualitative, exploratory and descriptive study with seven subjects. Data were collected through participative observation, semi structured interview, and a focus group from July to August of 2013. The data were subjected to content analysis. Results: The following thematic categories emerged: Women's work, informality and precariousness; Experiences of job satisfaction; and Working conditions and health: experiences with accidents, illness and health services. Conclusion: It was concluded that the women who collect recyclable material are exposed to precarious work conditions and potential health risks, such as work overload, accidents, illness, and social insecurity, and that nurses are responsible for promoting actions that ensure the health and inclusion of these workers. PMID- 27706443 TI - Social determinants of health and quality of life of caregivers of children with cancer. AB - Objective: to associate the social determinants of health and quality of life of caregivers of children with cancer. Methods: a cross-sectional study conducted in a paediatric cancer centre in Fortaleza, Brazil, with 176 participants in November and December 2013. Data were collected using a questionnaire with social determinants of health, and quality of life was assessed using the World Health Organization Quality of Life-Bref. The determinants were correlated with the averages of the quality of life domains using analysis of variance (ANOVA). Results: there was a statistically significant association between the domains of social relations and education (p = 0.01792) and between the psychosocial domain and the gender of the caregiver (p = 0.01901). The male caregivers that were highly educated, younger, married, stay-at-home dads from the interior had a better quality of life. Conclusion: the study sheds light on the influence of social determinants of health in the quality of life of caregivers of children with cancer. PMID- 27706444 TI - Model of transpersonal caring in nursing home care according to Favero and Lacerda: case report. AB - Objective: The aim of this paper is to report the experiences of applying a model of transpersonal caring in nursing home care according to Favero and Lacerda to adult patients after hematopoietic stem cell transplantation. Method: This is a case report on the application of this model to an outpatient monitored by a bone marrow transplant service. In addition to the initial outpatient contact, the patient received home care visits in October 2014. Data were recorded in the field diary and analysed according to the Care Model and Clinical Caritas Process. Results: The provided care served as support to meet basic human needs, and strengthen the belief system. It also promoted the necessary emotional care to cope with the treatment and professional maturity in the caring relationship. Conclusion: The experience description revealed that the model can support the application of the Theory of Human Caring in home care and the use of care models in practice, professional training, and research development. PMID- 27706445 TI - Defense strategies in the nursing work environment of long-stay institutions for the elderly. AB - Objective: To describe the defense strategies used by nurses working in long-stay institutions for the elderly when faced with work environment distress. Methodology: Descriptive, exploratory and qualitative research performed through interviews held with 27 nurses at long-stay institutions for the elderly between April and September 2013. Data analysis was performed through content analysis and the theory known as work psychodynamics. Results: The strategies used were: considering death as something natural, understanding death of those in critical condition as the end to a sufferable condition, understanding the patient's resistance as a symptom of disease and senility, limit the reach of work problems in their personal life, and restrict the affective involvement with patients. Conclusion: The nursing professionals indicated the development of individual defense strategies - grouped as protection, adaptation and exploitation measures in order to deal with situations that generate distress in their work environment. PMID- 27706446 TI - Infantile autism: impact of diagnosis and repercussions in family relationships. AB - Objective: To analyse the context in which the diagnosis of autism is revealed and the impact of this revelation on family relationships. Methods: This is a qualitative study with 10 families of autistic children assisted at the Psychosocial Care Centre for Children and Youths in a municipality of Paraiba. Data were collected between July and August 2013 through semi-structured interviews and interpreted using thematic content analysis. Results: The identified Main Unit of Analysis and the respective categories were: the impact of disclosing the diagnosis of autism to the family; characteristics of diagnosis disclosure: the place, time, and the dialogic relationship between the professional and the family; changes in family relationships and the mother's burden when caring for the autistic child. Conclusions: The health professionals who report autism should better prepare the family to cope with the difficulties of this syndrome and autonomously care for the autistic child.

AB - Background: Helicobacter pylori has a worldwide distribution and is associated with the pathogenesis of various diseases of the digestive system. Treatment to eradicate this microorganism involves the use of a combination of antimicrobials, such as amoxicillin, metronidazole, clarithromycin, and levofloxacin, combined with proton pump inhibitors. Although the current therapy is effective, a high rate of treatment failure has been observed, mainly because of the acquisition of point mutations, one of the major resistance mechanisms developed by H. pylori. This phenomenon is related to frequent and/or inappropriate use of antibiotics. Conclusion: This review reported an overview of the resistance to the main drugs used in the treatment of H. pylori, confirming the hypothesis that antibacterial resistance is a highly local phenomenon and genetic characteristics of a given population can influence which therapy is the most appropriate. PMID- 27706450 TI - IS THE IMMUNOCROMATOGRAPHIC FECAL ANTIGEN TEST EFFECTIVE FOR PRIMARY DIAGNOSIS OF HELICOBACTER PYLORI INFECTION IN DYSPEPTIC PATIENTS? AB - Background: The diagnosis of H. pylori infection can be performed by non-invasive and invasive methods.The identification through a fecal antigen test is a non invasive, simple, and relatively inexpensive test. Objective: To determine the diagnostic performance of fecal antigen test in the identification of H. pylori infection. Methods: H. pylori antigens were identified in the stools of dyspeptic patients undergoing upper gastrointestinal endoscopy. For the identification of H. pylori antigen, we use ImmunoCard STAT! HpSA with immunochromatography technique. Histopathology plus urease test were the gold standard. Results: We studied 163 patients, 51% male, mean age of 56.7+/- 8.5years. H. pylori infection was present in 49%. Fecal test presented: sensitivity 67.5% (CI95% 60.6-72.9); specificity 85.5% (CI95% 78.9-90.7); positive predictive value 81.8% (CI95% 73.4 88.4) and negative predictive value 73,2% (CI95% 67.5-77.6); Positive likelihood ratio was 4.7 (CI95% 2.9-7.9) and Negative Likelihood Ratio 0.4 (CI95% 0.3-0.5). The prevalence odds ratio for a positive test was 12.3 (CI95% 5.7-26.3).The index kappa between FAT and histology/urease test was 0.53 (CI95% 0.39-0.64). Conclusion: Immunochromatographic FAT is less expensive than the other methods and readily accepted by the patients but its diagnostic performance does not recommend its use in the primary diagnosis, when the patient may have an active infection. PMID- 27706452 TI - EARLY AND LATE ASSESSMENT OF ESOPHAGOCARDIOPLASTY IN THE SURGICAL TREATMENT OF ADVANCED RECURRENT MEGAESOPHAGUS. AB - Background: Since Chagas disease has esophageal manifestations with different degrees of involvement, the best surgical option is controversial, especially for patients with advanced chagasic megaesophagus and recurrent symptoms after previous treatment. Objective: To assess the early and late outcomes of esophagocardioplasty in a series of patients with advanced recurrent chagasic megaesophagus. Methods: This descriptive study included 19 older patients with recurrent megaesophagus grade III/IV and positive immunofluorescence for Chagas disease. They had undergone cardiomyotomy with anterior fundoplication a mean of 16.5 years ago. Serra-Doria esophagocardioplasty was selected to treat the recurrence. The patients were followed to assess postoperative and late complications and the incidence of symptom recurrence. Results: In early assessment, five (26.3%) patients presented clinical complications. One (5.2%) patient had a gastrointestinal fistula secondary to esophagogastric anastomotic leak, which responded well to conservative treatment. In the one-year follow-up, 18 (94.7%) patients could swallow normally and had no vomiting. Three years after surgery, 10 (62.5%) of 16 patients could swallow normally, and 3 (19.3%) patients complained of vomiting. Five years after surgery, only 5 (38.4%) of 13 patients could swallow normally and 7 (53.8%) had vomiting. Conclusion: Serra-Doria esophagocardioplasty for the treatment of advanced recurrent megaesophagus had mild postoperative complications and good success rate in the short-term follow up. In the long-term follow-up, it proved to be a poor surgery choice because of the high incidence of symptom recurrence, compromising quality of life. This procedure should be indicated only for patients with advanced recurrent megaesophagus without clinical conditions to undergo esophageal resection. PMID- 27706451 TI - ORAL ADMINISTRATION OF EXOGENOUS LACTASE IN TABLETS FOR PATIENTS DIAGNOSED WITH LACTOSE INTOLERANCE DUE TO PRIMARY HYPOLACTASIA. AB - Background: Primary hypolactasia is a common condition where a reduced lactase activity in the intestinal mucosa is present. The presence of abdominal symptoms due to poor absorption of lactose, which are present in some cases, is a characteristic of lactose intolerance. Objective: Evaluate the efficacy of a product containing exogenous lactase in tablet form compared to a reference product with proven effectiveness in patients with lactose intolerance. Methods: Multicentre, randomized, parallel group, single-blind, comparative non inferiority study. One hundred twenty-nine (129) adult lactose intolerance patients with hydrogen breath test results consistent with a diagnosis of hypolactasia were randomly assigned to receive the experimental product (Perlatte(r) - Eurofarma Laboratorios S.A.) or the reference product (Lactaid(r) McNeilNutritionals, USA) orally (one tablet, three times per day) for 42 consecutive days. Results: Data from 128 patients who actually received the studied treatments were analysed (66 were treated with the experimental product and 62 with the reference product). The two groups presented with similar baseline clinical and demographic data. Mean exhaled hydrogen concentration tested at 90 minutes after the last treatment (Day 42) was significantly lower in the experimental product treated group (17+/-18 ppm versus 34+/-47 ppm) in the per protocol population. The difference between the means of the two groups was 17 ppm (95% confidence interval [95% CI]: -31.03; -3.17). The upper limit of the 95% CI did not exceed the a priori non-inferiority limit (7.5 ppm). Secondary efficacy analyses confirmed that the treatments were similar (per protocol and intention to treat population). The tolerability was excellent in both groups, and there were no reports of serious adverse events related to the study treatment. Conclusion: The experimental product was non-inferior to the reference product, indicating that it was an effective replacement therapy for endogenous lactase in lactose intolerance patients. PMID- 27706453 TI - IS DIGITAL RECTAL EXAM RELIABLE IN GRADING ANAL SPHINCTER DEFECTS? AB - Background: Anal sphincter tone is routinely assessed by digital rectal examination in patients with fecal incontinence, although its accuracy in detecting sphincter defects or separating competent from incompetent muscles has not been established. Objective: In this setting, we aimed to evaluate the accuracy of digital rectal examination in grading anal defects in order to separate small from extensive cases as depicted on 3D endoanal ultrasound, using a scoring sphincter defect and correlate anal tone to anal pressures. Methods: Women with fecal incontinence were divided into two groups: small or extensive defects according to the ultrasound scoring system. Sensitivity, specificity, positive and negative predictive values of digital rectal examination in grading global and external sphincter defects were calculated. Anal tone at digital rectal examination was compared to resting and incremental pressures. Results: A cohort of 76 consecutive incontinent women were enrolled. The median Wexner score was 9. Sixty-eight showed sphincter defects on 3D endoanal ultrasound. Anal tone at digital rectal examination was considered abnormal in 62 cases. Abnormal digital rectal examination showed a sensitivity of 90%, specificity of 27.78% in distinguishing small from extensive defects of both sphincters. Five out of eight women with no sphincter defects had only abnormal squeeze tone at digital rectal examination. Abnormal squeeze tone at digital rectal examination had a sensitivity of 65.31% in distinguishing small from extensive external anal sphincter defects. Digital rectal examination sensitivity increased linearly from small to extensive external anal sphincter defects (P=0.001). Women with abnormal resting tone had lower resting pressures than women with normal tone at digital rectal examination (P=0.0001). Women with abnormal squeeze tone had lower incremental pressures than women with normal tone at digital rectal examination (P=0.017). Conclusion: Digital rectal examination had good sensitivity and poor specificity in discerning small from severe global anal sphincter defects. Moreover, digital rectal examination had fair sensitivity and poor specificity in grading external anal sphincter defects, and its best accuracy was on complete external anal sphincter lesions. Anal resting and squeeze tone were correlated to anal pressures. PMID- 27706454 TI - FREQUENCY OF THE MDR1 GENE POLYMORPHISM RS1045642 (C3435T) IN HCV-HIV CO-INFECTED PATIENTS. AB - Background: Due to the high prevalence of co-infection by hepatitis C virus (HCV) and human immunodeficiency virus (HIV) and the severity of these infections, the understanding of the biological mechanisms involved in these processes, including viral behavior and host genetic profile, is of great importance for patient treatment and for public health policies.Some single nucleotide polymorphisms (SNPs) in the human genome, such as the SNP rs1045642 (C3435T) in the MDR1 gene, have been reported to be associated to the sustained virological response (SVR) to HCV treatment in HCV-HIV co-infected patients. Objective: The present study analyzes the MDR1 gene C3435T polymorphism in HCV-HIV co-infected patients. Methods: A total of 99 HCV-HIV patients were included in the study. The DNA was extracted from blood samples, and the SNP rs1045642 was assessed by Real Time PCR (qPCR). Risk factors for acquiring the virus and the SVR after HCV treatment with pegylated interferon-alpha and ribavirin were also analyzed. Results: Among the patients, 54 (54.5%) were male and 45 (45.5%) were female. The average age was 46.1+/-9.8 years. The SVR after HCV treatment was 40%. The frequencies of MDR1 genotypes CC, CT and TT were 28.3%, 47.5% and 24.2%, respectively. Allele frequencies were 52% for the C allele and 48% for the T allele. No association was found for SNP rs1045642 (C3435T) regarding response to treatment (P=0.308). Conclusion: - In this study, the C3435T polymorphism in the MDR1 gene appears not to be associated with SVR in HCV-HIV co-infected individuals. PMID- 27706455 TI - FOOD CONSUMPTION OF CIRRHOTIC PATIENTS, COMPARISON WITH THE NUTRITIONAL STATUS AND DISEASE STAGING. AB - Background: Patients with liver disease often present protein-energy malnutrition. The assessment of food intake is very important in the investigation regarding the "health-disease" process. Objective: To assess dietary intake of cirrhotic patients through food record during 3 days, correlating it with the nutritional status of the patient and the stage of the disease. Methods: Cirrhotic outpatients from the Santa Casa de Misericordia Hospital, RS, Brazil, were assessed. Nutritional assessment was performed by anthropometry; non-dominating handgrip strength; adductor pollicis muscle thickness; phase angle by bioelectrical impedance analysis; and Subjective Global Assessment. For analysis of food consumption we used the food records of 3 days using scales for weighing of all foods. Results: We evaluated 25 (68%) patients, in which there was a prevalence of cirrhosis by hepatitis C virus. The upper arm circumference, handgrip strength and phase angle by bioelectrical impedance analysis diagnosed 56% of malnourished. Phase angle by bioelectrical impedance analysis and upper arm circumference were associated with Child-Pugh score (P<0.05). The average consumption of calories, carbohydrates, proteins and lipids were within the recommended. However, sodium was above the recommendations, 106+/ 57.2 mEq, and was inversely associated with Child-Pugh score (rs=-0.410; P=0.042). Conclusion: Food intake did not have a significant difference between the Child-Pugh scores and nutritional status. In addition, food intake did not vary neither according to the stage of the disease, nor to the nutritional assessment, by the phase angle by bioelectrical impedance analysis. PMID- 27706456 TI - EVALUATION OF PRIMARY PROPHYLAXIS WITH PROPRANOLOL AND ELASTIC BAND LIGATION IN VARICEAL BLEEDING IN CIRRHOTIC CHILDREN AND ADOLESCENTS. AB - Background: The efficacy of nonselective beta-blocker and endoscopic procedures, such as endoscopic variceal ligation, as primary prophylaxis of variceal hemorrhage in cirrhotic adults was demonstrated by numerous controlled trials, but in pediatric population, few are the number of studies. Objective: The objective of this study is to evaluate the primary prophylaxis with beta-blocker in cirrhotic children and adolescents with portal hypertension. Methods: This is a cohort study encompassing 26 cirrhotic patients. beta-blocker prophylaxis was performed with propranolol. When contraindicated the use of beta-blocker, or if side effects presents, the patients were referred to endoscopic therapy with band ligation. Patients were evaluated by endoscopy, and those who had varicose veins of medium and large caliber or reddish spots, regardless of the caliber of varices, received primary prophylaxis. Results: Of the 26 patients evaluated, 9 (34.6%) had contraindications to the use of propranolol and were referred for endoscopic prophylaxis. Six (35.3%) of the 17 patients who received beta-blocker (propranolol), had bled after a median follow-up time of 1.9 years. beta-blockage dosage varied from 1 mg/kg/day to 3.1 mg/kg/day and seven (41.2%) patients had the propranolol suspended due to fail of the beta-blockage or adverse effects, such as drowsiness, bronchospasm and hypotension. Patients who received endoscopic prophylaxis (elastic bandage) had no bleeding during the follow-up period. Conclusion: All of the patients that had upper gastroinstestinal bleeding in this study were under propranolol prophylaxis. The use of propranolol showed a high number of contraindications and side effects, requiring referral to endoscopic prophylaxis. The endoscopic prophylaxis was effective in reducing episodes of bleeding. PMID- 27706457 TI - ALLERGIC PROCTOCOLITIS IN INFANTS: analysis of the evolution of the nutritional status. AB - Background: Allergic proctocolitis is a disease that affects infants in the first months. The change in feed is the primary factor for clinical improvement and maintenance of the nutritional status of the infant. Objective: Study the anthropometric evolution of infants with allergic proctocolitis at diagnosis and 1 to 6 months after nutritional intervention. Methods: A retrospective cohort of infants with allergic proctocolitis diagnosis followed at the Pediatric Gastroenterology Institute of Sao Paulo (IGASTROPED), Brazil. The database with clinical, therapeutic and anthropometric data was obtained from medical records of outpatient infants. The therapeutic intervention was characterized by 1) exclusive breastfeeding with maternal exclusion diet of the six allergens (EBF MED) or 2) no breastfeeding and use of hypoallergenic formulas. Results: Of the 44 infants diagnosed with allergic proctocolitis, 23 were female. The median age of the infants was 3.5 months at the time of admission and 6 months after the intervention. The main clinical complaint was hematochezia with or without other symptoms of allergic proctocolitis. No difference was shown in the infants anthropometric evaluation between the two diets. Conclusion: The duration of the allergic proctocolitis did not induce worsening of the infants nutritional status. Importantly, both nutritional interventions were able to keep the infants within the growth channel and resulted in the total clinical symptoms remission. Considering the fundamental mother-child link promoted by breastfeeding, the present data highlights the beneficial role of EBF-MED on the nutritional status of infants diagnosed with allergic proctocolitis in addition to the lower cost that breastfeeding brings compared the use of hypoallergenic formulas. PMID- 27706458 TI - PREVALENCE OF GENETIC SUSCEPTIBILITY FOR CELIAC DISEASE IN BLOOD DONORS IN SAO PAULO, BRAZIL. AB - Background: Celiac disease is a permanent intolerance induced by gluten, which is expressed by T-cell mediated enteropathy, and has a high prevalence in the general population. There is evidence of a strong genetic predisposition to celiac disease. Objective: To determine the prevalence of genetic markers HLA-DQ2 and HLA-DQ8 in blood donors from Sao Paulo and measure human recombinant tissue transglutaminase antibody IgA class in HLA-DQ2 and HLA-DQ8 positive donors. Methods: A total of 404 blood donors from Sao Paulo city and Jundiai were included in the study and signed the informed consent form. Information regarding diarrhea, constipation and abdominal pain in the last 3 months was collected. Determination of HLADQ2 and HLADQ8 alleles was performed in all participants and human recombinant tissue transglutaminase antibody class IgA was measured only in blood donors who presentedDQ2 and/or DQ8. Results: HLADQ2 and/or HLADQ8 were positive in 49% (198/404) of subjects. Positive samples were associated with alleles DR3, DR4, DR7, DR11 and DR12. The most frequent genotype was DR4-DQ8, which was present in 13.6% of samples, followed by genotypes DR3-DQ2 and DR7-DQ2 with DQB1*02 in heterozygous, which were present in 10.4% and 8.7%, respectively. Eleven out of 198 positive donors (5%) were positive to human tissue transglutaminase test. Conclusion: We observed a high prevalence of genetic markers for celiac disease, HLA-DQ2 and HLA-DQ8, in blood donors from Sao Paulo, similar to prevalence described in Europe. These findings show that the prevalence of celiac disease should not be rare in our country, but underdiagnosed. PMID- 27706459 TI - LONG-TERM POSTOPERATIVE ENDOSCOPIC FINDINGS AFTER GASTRIC BYPASS PROCEDURE: a co occurrence analysis. AB - Background: A multitude of endoscopic findings post-gastric bypass procedures have been previously reported in the literature, but to our knowledge, no present rules exist that could guide clinicians regarding which findings should be actively sought, once an initial finding is identified. Objective: To identify co occurrence patterns among endoscopic findings of patients having undergone past gastric bypass procedure. Methods: Our registry involves all consecutive patients undergoing an upper endoscopic evaluation after a gastric bypass procedure. We collected information on the presence of the endoscopic findings in post-gastric bypass surgery patients. Co-occurrence evaluation involved the use of intersection, cluster and item factor analyses. Results: A total of 396 endoscopic evaluations were made on 339 patients. Most patients were female (81.1%), with an average BMI of 31.88+/-6.7 at the time of endoscopy. Esophagitis was the most common isolated finding (35.3%). Endoscopic findings clustered around two groups, (1) the ring-related complications involving ring displacement, ring slips and gastric pouch, while (2) stenosis-related findings involved dilation and stenosis (P<0.01). Conclusion: While most endoscopic findings after gastric bypass endoscopic procedures are isolated, ring and stenosis-related clusters should be used as a set of rules by clinicians, as it might enhance their probability of finding co-occurring conditions. PMID- 27706461 TI - Erratum. AB - [This corrects the article doi: 10.1590/S0004-28032016000300001]. PMID- 27706460 TI - ALTERATION OF TASTE BUDS IN EXPERIMENTAL CIRRHOSIS. Is there correlation with human hypogeusia? AB - Background: The inherent complications of cirrhosis include protein-calorie malnutrition and micronutrient deficiencies.Changes in taste are detrimental to the nutritional status, and the mechanism to explain these changes is not well documented in the cirrhotic patients. Objective: To evaluate the taste buds of cirrhotic rats. Methods: Fourteen male Wistar rats were evaluated. After 16 weeks, the liver was removed to histologically diagnose cirrhosis, and blood was collected to perform liver integrity tests. The tongue was removed for histological examination and immunohistochemistry using antibodies against protein gene product PGP 9.5 and the sweet taste receptors T1R2 and T1R3. Morphological changes were determined by scanning electron microscopy. Serum zinc levels were measured. Results: The cirrhotic animals, but not the control animals, exhibited zinc deficiency. In both groups, there was positive immunoreactivity for type II and III cells and T1R2 receptors. The cirrhotic animals had no immunoreactivity for T1R3 receptors. Scanning electron microscopy analysis of the cirrhotic group revealed a uniform tapering of the gustatory papillae. Conclusion: In conclusion the experimental cirrhosis model mimicked the biochemical and histological parameters of human cirrhosis, therefore enabling a study of the gustatory papillae and taste buds. PMID- 27706462 TI - Effectiveness of prophylactic non-invasive ventilation on respiratory function in the postoperative phase of pediatric cardiac surgery: a randomized controlled trial. AB - Objective: To evaluate the effectiveness of prophylactic, non-invasive ventilation (NIV) on respiratory function in seven- to 16-year-old children in the post-operative phase of cardiac surgery. Method: A randomized, controlled trial with 50 children who had undergone cardiac surgery with median sternotomy. After extubation, patients were randomly assigned to one of two groups: control group (n=26), which received instructions regarding posture, early ambulation, and cough stimulation, and CPAP group (continuous positive airway pressure; n=24), which received the same instructions as the control group and CPAP=10 cmH20 twice daily for 30 minutes from the 1st to the 5th post-operative day (POD). As a primary outcome, lung function was evaluated before and on the 1st, 3rd, and 5th PODs with measures of respiratory rate (RR), tidal volume (TV), slow vital capacity (SVC), inspiratory capacity (IC), minute volume (MV), peak expiratory flow (PEF), and maximal inspiratory pressure (MIP). As secondary outcomes, the time of hospitalization and intensive care were recorded. A mixed, linear regression model and z-test were used to analyze respiratory function, considering p<0.05. Results: All variables, except RR and MV, showed a significant drop on the 1st POD, with gradual recovery; however, only MIP had returned to pre-operative values on the 5th POD in both groups. The RR showed a significant increase on the 1st POD, with a gradual reduction but without returning to baseline. In the intergroup analysis, significant improvement (p=0.04) was observed only in PEF in the CPAP group on the 1st DPO. The length of hospitalization and intensive care showed no significant differences. Conclusion: NIV was safe and well accepted in this group of patients, and the protocol used was effective in improving PEF on the 1st DPO in the CPAP group.

PMID- 27706464 TI - Effect of Postextubation High-Flow Nasal Cannula vs Noninvasive Ventilation on Reintubation and Postextubation Respiratory Failure in High-Risk Patients: A Randomized Clinical Trial. AB - Importance: High-flow conditioned oxygen therapy delivered through nasal cannulae and noninvasive mechanical ventilation (NIV) may reduce the need for reintubation. Among the advantages of high-flow oxygen therapy are comfort, availability, lower costs, and additional physiopathological mechanisms. Objective: To test if high-flow conditioned oxygen therapy is noninferior to NIV for preventing postextubation respiratory failure and reintubation in patients at high risk of reintubation. Design, Setting, and Participants: Multicenter randomized clinical trial in 3 intensive care units in Spain (September 2012 October 2014) including critically ill patients ready for planned extubation with at least 1 of the following high-risk factors for reintubation: older than 65 years; Acute Physiology and Chronic Health Evaluation II score higher than 12 points on extubation day; body mass index higher than 30; inadequate secretions management; difficult or prolonged weaning; more than 1 comorbidity; heart failure as primary indication for mechanical ventilation; moderate to severe chronic obstructive pulmonary disease; airway patency problems; or prolonged mechanical ventilation. Interventions: Patients were randomized to undergo either high-flow conditioned oxygen therapy or NIV for 24 hours after extubation. Main Outcomes and Measures: Primary outcomes were reintubation and postextubation respiratory failure within 72 hours. Noninferiority margin was 10 percentage points. Secondary outcomes included respiratory infection, sepsis, and multiple organ failure, length of stay and mortality; adverse events; and time to reintubation. Results: Of 604 patients (mean age, 65 [SD, 16] years; 388 [64%] men), 314 received NIV and 290 high-flow oxygen. Sixty-six patients (22.8%) in the high-flow group vs 60 (19.1%) in the NIV group were reintubation (absolute difference, -3.7%; 95% CI, -9.1% to infinity); 78 patients (26.9%) in the high flow group vs 125 (39.8%) in the NIV group experienced postextubation respiratory failure (risk difference, 12.9%; 95% CI, 6.6% to infinity) [corrected]. Median time to reintubation did not significantly differ: 26.5 hours (IQR, 14-39 hours) in the high-flow group vs 21.5 hours (IQR, 10-47 hours) in the NIV group (absolute difference, -5 hours; 95% CI, -34 to 24 hours). Median postrandomization ICU length of stay was lower in the high-flow group, 3 days (IQR, 2-7) vs 4 days (IQR, 2-9; P=.048). Other secondary outcomes were similar in the 2 groups. Adverse effects requiring withdrawal of the therapy were observed in none of patients in the high-flow group vs 42.9% patients in the NIV group (P < .001). Conclusions and Relevance: Among high-risk adults who have undergone extubation, high-flow conditioned oxygen therapy was not inferior to NIV for preventing reintubation and postextubation respiratory failure. High-flow conditioned oxygen therapy may offer advantages for these patients. Trial Registration: clinicaltrials.gov Identifier: NCT01191489. PMID- 27706465 TI - Same-Day Discharge After Percutaneous Coronary Intervention-Reply. PMID- 27706466 TI - Effect of Conservative vs Conventional Oxygen Therapy on Mortality Among Patients in an Intensive Care Unit: The Oxygen-ICU Randomized Clinical Trial. AB - Importance: Despite suggestions of potential harm from unnecessary oxygen therapy, critically ill patients spend substantial periods in a hyperoxemic state. A strategy of controlled arterial oxygenation is thus rational but has not been validated in clinical practice. Objective: To assess whether a conservative protocol for oxygen supplementation could improve outcomes in patients admitted to intensive care units (ICUs). Design, Setting, and Patients: Oxygen-ICU was a single-center, open-label, randomized clinical trial conducted from March 2010 to October 2012 that included all adults admitted with an expected length of stay of 72 hours or longer to the medical-surgical ICU of Modena University Hospital, Italy. The originally planned sample size was 660 patients, but the study was stopped early due to difficulties in enrollment after inclusion of 480 patients. Interventions: Patients were randomly assigned to receive oxygen therapy to maintain Pao2 between 70 and 100 mm Hg or arterial oxyhemoglobin saturation (Spo2) between 94% and 98% (conservative group) or, according to standard ICU practice, to allow Pao2 values up to 150 mm Hg or Spo2 values between 97% and 100% (conventional control group). Main Outcomes and Measures: The primary outcome was ICU mortality. Secondary outcomes included occurrence of new organ failure and infection 48 hours or more after ICU admission. Results: A total of 434 patients (median age, 64 years; 188 [43.3%] women) received conventional (n = 218) or conservative (n = 216) oxygen therapy and were included in the modified intent-to-treat analysis. Daily time-weighted Pao2 averages during the ICU stay were significantly higher (P < .001) in the conventional group (median Pao2, 102 mm Hg [interquartile range, 88-116]) vs the conservative group (median Pao2, 87 mm Hg [interquartile range, 79-97]). Twenty-five patients in the conservative oxygen therapy group (11.6%) and 44 in the conventional oxygen therapy group (20.2%) died during their ICU stay (absolute risk reduction [ARR], 0.086 [95% CI, 0.017-0.150]; relative risk [RR], 0.57 [95% CI, 0.37-0.90]; P = .01). Occurrences were lower in the conservative oxygen therapy group for new shock episode (ARR, 0.068 [95% CI, 0.020-0.120]; RR, 0.35 [95% CI, 0.16-0.75]; P = .006) or liver failure (ARR, 0.046 [95% CI, 0.008-0.088]; RR, 0.29 [95% CI, 0.10-0.82]; P = .02) and new bloodstream infection (ARR, 0.05 [95% CI, 0.00-0.09]; RR, 0.50 [95% CI, 0.25-0.998; P = .049). Conclusions and Relevance: Among critically ill patients with an ICU length of stay of 72 hours or longer, a conservative protocol for oxygen therapy vs conventional therapy resulted in lower ICU mortality. These preliminary findings were based on unplanned early termination of the trial, and a larger multicenter trial is needed to evaluate the potential benefit of this approach.

PMID- 27706467 TI - Cardiovascular Biomarker Score and Clinical Outcomes in Patients With Atrial Fibrillation: A Subanalysis of the ENGAGE AF-TIMI 48 Randomized Clinical Trial. AB - Importance: Treatment decisions in atrial fibrillation (AF) are based on clinical assessment of risk. The CHA2DS2-VASc (cardiac failure or dysfunction, hypertension, age 65-74 [1 point] or >=75 years [2 points], diabetes mellitus, and stroke, transient ischemic attack or thromboembolism [2 points]-vascular disease, and sex category [female]) risk score is pragmatic and widely used but has only moderate discrimination. Objective: To develop and test a cardiovascular biomarker score for indication of risk in patients with AF. Design, Setting, and Participants: The ENGAGE AF-TIMI 48 trial was a randomized, double-blind, double dummy clinical trial comparing 2 once-daily edoxaban dose regimens with warfarin in 21 105 patients with AF at moderate to high risk of stroke. This prespecified subanalysis was performed in 4880 patients enrolled at randomization in the biomarker substudy. Cardiac troponin I, N-terminal pro-B-type natriuretic peptide, and d-dimer levels were measured at baseline. A multimarker risk score was developed to determine the probability of stroke, systemic embolic events, or death by assigning tiered points for higher concentrations of the biomarkers. Main Outcomes and Measures: Risk score and clinical outcomes based on cardiac troponin I, N-terminal pro-B-type natriuretic peptide, and d-dimer levels at baseline. Results: Of the 5002 patients enrolled in the biomarker substudy of the ENGAGE AF-TIMI 48 trial, 4880 patients (97.6%) had all 3 biomarkers available at randomization (1820 [37.3%] were women; median [interquartile range] age, 71 [64 77] years). After adjustment for the CHA2DS2-VASc score, each biomarker was associated with a 2.8-fold to 4.2-fold gradient of risk comparing the highest vs lowest concentrations across groups of increasing concentrations (P < .001 for trend for each). The multimarker risk score identified a more than 15-fold gradient of risk after adjustment for CHA2DS2-VASc score. When added to the CHA2DS2-VASc score, the biomarker score significantly enhanced prognostic accuracy by improving the C statistic from 0.586 (95% CI, 0.565-0.607) to 0.708 (95% CI, 0.688-0.728) (P < .001) and reclassification with a net reclassification improvement of 59.4% (P < .001). Conclusions and Relevance: A prototype multimarker risk score significantly enhanced risk assessment for stroke, systemic embolic events, or death compared with traditional clinical risk stratification. Incorporation of biomarkers into clinical decision making to define therapeutic management in AF warrants consideration. Trial Registration: clinicaltrials.gov Identifier: NCT00781391.

PMID- 27706469 TI - Oxygen in the ICU: Too Much of a Good Thing? PMID- 27706470 TI - Comparison of Approaches for Heart Failure Case Identification From Electronic Health Record Data. AB - Importance: Accurate, real-time case identification is needed to target interventions to improve quality and outcomes for hospitalized patients with heart failure. Problem lists may be useful for case identification but are often inaccurate or incomplete. Machine-learning approaches may improve accuracy of identification but can be limited by complexity of implementation. Objective: To develop algorithms that use readily available clinical data to identify patients with heart failure while in the hospital. Design, Setting, and Participants: We performed a retrospective study of hospitalizations at an academic medical center. Hospitalizations for patients 18 years or older who were admitted after January 1, 2013, and discharged before February 28, 2015, were included. From a random 75% sample of hospitalizations, we developed 5 algorithms for heart failure identification using electronic health record data: (1) heart failure on problem list; (2) presence of at least 1 of 3 characteristics: heart failure on problem list, inpatient loop diuretic, or brain natriuretic peptide level of 500 pg/mL or higher; (3) logistic regression of 30 clinically relevant structured data elements; (4) machine-learning approach using unstructured notes; and (5) machine-learning approach using structured and unstructured data. Main Outcomes and Measures: Heart failure diagnosis based on discharge diagnosis and physician review of sampled medical records. Results: A total of 47 119 hospitalizations were included in this study (mean [SD] age, 60.9 [18.15] years; 23 952 female [50.8%], 5258 black/African American [11.2%], and 3667 Hispanic/Latino [7.8%] patients). Of these hospitalizations, 6549 (13.9%) had a discharge diagnosis of heart failure. Inclusion of heart failure on the problem list (algorithm 1) had a sensitivity of 0.40 and a positive predictive value (PPV) of 0.96 for heart failure identification. Algorithm 2 improved sensitivity to 0.77 at the expense of a PPV of 0.64. Algorithms 3, 4, and 5 had areas under the receiver operating characteristic curves of 0.953, 0.969, and 0.974, respectively. With a PPV of 0.9, these algorithms had associated sensitivities of 0.68, 0.77, and 0.83, respectively. Conclusions and Relevance: The problem list is insufficient for real-time identification of hospitalized patients with heart failure. The high predictive accuracy of machine learning using free text demonstrates that support of such analytics in future electronic health record systems can improve cohort identification.

AB - Importance: Treating surgical complications presents a major challenge for hospitals striving to deliver high-quality care while reducing costs. Costs associated with rescuing patients from perioperative complications are poorly characterized. Objective: To evaluate differences across hospitals in the costs of care for patients surviving perioperative complications after major inpatient surgery. Design, Setting, and Participants: Retrospective cohort study using claims data from the Medicare Provider Analysis and Review files. We compared payments for patients who died vs patients who survived after perioperative complications occurred. Hospitals were stratified using average payments for patients who survived following complications, and payment components were analyzed across hospitals. Administrative claims database of surgical patients was analyzed at hospitals treating Medicare patients nationwide. This study included Medicare patients aged 65 to 100 years who underwent abdominal aortic aneurysm repair (n = 69 207), colectomy for cancer (n = 107 647), pulmonary resection (n = 91 758), and total hip replacement (n = 307 399) between 2009 and 2012. Data analysis took place between November 2015 and March 2016. Exposures: Clinical outcome of surgery (eg, no complication, complication and death, or complication and survival) and the individual hospital where a patient received an operation. Main Outcomes and Measures: Risk-adjusted, price-standardized Medicare payments for an episode of surgery. Risk-adjusted perioperative outcomes were also assessed. Results: The mean age for Medicare beneficiaries in this study ranged from 74.1 years (pulmonary resection) to 78.2 years (colectomy). The proportion of male patients ranged from 37% (total hip replacement) to 77% (abdominal aortic aneurysm repair), and most patients were white. Among patients who experienced complications, those who were rescued had higher price standardized Medicare payments than did those who died for all 4 operations. Assessing variation across hospitals, payments for patients who were rescued at the highest cost-of-rescue hospitals were 2- to 3-fold higher than at the lowest cost-of-rescue hospitals for abdominal aortic aneurysm repair ($60 456 vs $23 261; P < .001), colectomy ($56 787 vs $22 853; P < .001), pulmonary resection ($63 117 vs $21 325; P < .001), and total hip replacement ($41 354 vs $19 028; P < .001). Compared with lowest cost-of-rescue hospitals, highest cost-of-rescue hospitals had higher risk-adjusted rates of serious complications with similar rates of failure to rescue and overall 30-day mortality. Conclusions and Relevance: After 4 selected inpatient operations, substantial variation was observed across hospitals regarding Medicare episode payments for patients rescued from perioperative complications. Notably, higher Medicare payments were not associated with improved clinical performance. These findings highlight the potential for hospitals to target efficient treatment of perioperative complications in cost-reduction efforts. PMID- 27706474 TI - Omitted Reference.

AB - Importance: Perinatal complications may increase the risk of obsessive-compulsive disorder (OCD). Previous reports were based on small, retrospective, specialist clinic-based studies that were unable to rigorously control for unmeasured environmental and genetic confounding. Objective: To prospectively investigate a wide range of potential perinatal risk factors for OCD, controlling for unmeasured factors shared between siblings in the analyses. Design, Setting, and Participants: This population-based birth cohort study included all 2 421 284 children from singleton births in Sweden from January 1, 1973, to December 31, 1996, who were followed up through December 31, 2013. From the 1 403 651 families in the cohort, differentially exposed siblings from the 743 885 families with siblings were evaluated; of these, 11 592 families included clusters of full siblings that were discordant for OCD. Analysis of the data was conducted from January, 26, 2015, to September, 5, 2016. Exposures: Perinatal data were collected from the Swedish Medical Birth Register and included maternal smoking during pregnancy, labor presentation, obstetric delivery, gestational age (for preterm birth), birth weight, birth weight in relation to gestational age, 5 minute Apgar score, and head circumference. Main Outcomes and Measures: Previously validated OCD codes (International Statistical Classification of Diseases and Health Related Problems, Tenth Revision, code F42) in the Swedish National Patient Register. Results: Of 2 421 284 individuals included in the cohort, 17 305 persons were diagnosed with OCD. Of these, 7111 were men (41.1%). The mean (SD) age of individuals at first diagnosis of OCD was 23.4 (6.5) years. An increased risk for OCD remained after controlling for shared familial confounders and measured covariates (including sex, year of birth, maternal and paternal age at birth, and parity), for smoking 10 or more cigarettes per day during pregnancy (hazard ratio [HR], 1.27; 95% CI, 1.02-1.58), breech presentation (HR, 1.35; 95% CI, 1.06-1.71), delivery by cesarean section (HR, 1.17; 95% CI, 1.01-1.34), preterm birth (HR, 1.24; 95% CI, 1.07-1.43), birth weight 1501 to 2500 g (HR, 1.30; 95% CI, 1.05-1.62) and 2501 to 3500 g (HR, 1.08; 95% CI, 1.01-1.16), being large for gestational age (HR, 1.23; 95% CI, 1.05 1.45), and Apgar distress scores at 5 minutes (HR, 1.50; 95% CI, 1.07-2.09). Gestational age and birth weight followed inverse dose-response associations, whereby an increasingly higher risk for OCD was noted in children with a shorter gestational age and lower birth weight. We also observed a dose-response association between the number of perinatal events and increased OCD risk, with HRs ranging from 1.11 (95% CI, 1.07-1.15) for 1 event to 1.51 (95% CI, 1.18-1.94) for 5 or more events. Conclusions and Relevance: A range of perinatal risk factors is associated with a higher risk for OCD independent of shared familial confounders, suggesting that perinatal risk factors may be in the causal pathway to OCD.

Little is known about the characteristics of industry payments to dermatologists. Objective: To analyze the nature and extent of industry payments to dermatologists. Design, Setting, and Participants: This was a retrospective review using the publicly available Centers for Medicare and Medicaid Services (CMS) Sunshine Act Open Payment database. Data were downloaded from the publically available CMS website under General Payment and Research Payment data sets. All payments to dermatologists from companies making products reimbursed by a government-run health program were reviewed. Main Outcomes and Measures: Mean, median, and range of payments made, including quantity and total sum of payments, per clinician. Total payments and number of transactions per category of payment, geographic region, and payment source were also assessed. Results: A total of 8333 dermatologists received 208 613 payments totaling more than $34 million. The median total payment per dermatologist was $298 with an interquartile range of $99 to $844. The top 10% of dermatologists (n = 833) received more than $31.2 million, 90% of the total payments. The top 1% each (n = 83) received at least $93 622 and accounted for 44% of total payments. While 83% of payment entries were for food and beverage, they accounted for only 13% of total amount of payments. Speaker fees (31.7%), consulting fees (21.6%), and research payments (16.5%) comprised 69.8% of total payment amount. The top 15 companies were all pharmaceutical manufacturers and paid dermatologists $28.7 million, representing 81% of total disbursement. Conclusions and Relevance: Dermatologists received substantial payments from the pharmaceutical industry. The nature and amount of payments varied widely. The impact of the data on patient care, physicians practice patterns, and patient perception of physicians is unclear.

PMID- 27706479 TI - Evaluation of Patients With Hepatocellular Carcinomas That Do Not Produce alpha Fetoprotein. AB - Importance: Serum alpha-fetoprotein (AFP) is a biomarker for hepatocellular carcinomas (HCCs) associated with a more aggressive tumor phenotype and inferior outcomes after a liver transplant (LT). Data on the outcomes for patients with HCCs that do not produce AFP are limited. Objective: To compare characteristics and outcomes among LT recipients with radiographically apparent HCC lesions with AFP-producing tumors or with tumors that do not produce AFP (hereafter referred to as non-AFP-producing tumors), and to identify factors influencing recurrence in LT recipients with non-AFP-producing tumors. Design, Setting, and Participants: Retrospective analysis at a university transplant center of 665 adults with HCC who underwent an LT during the period from 1989 to 2013. Of the 665 LT recipients, 457 (68.7%) had AFP-producing tumors, and 208 (31.3%) had non AFP-producing tumors (the maximum AFP level before an LT was <=10 ng/mL). Dates of study analysis were from August 2015 to June 2016. Intervention: Liver transplant. Main Outcomes and Measures: Recurrence-free survival and recurrence rates. Results: Patients with non-AFP-producing tumors had radiographic tumor characteristics similar to those of patients with AFP-producing tumors, but, pathologically, they had fewer lesions (25% vs 35% with >2 lesions; P = .03), smaller cumulative tumor diameters (4.2 vs 5.0 cm; P = .02), fewer microvascular (17% vs 22%) and macrovascular (2% vs 9%) invasions (P < .001), and fewer poorly differentiated tumors (15% vs 28%; P < .001). Patients with non-AFP-producing tumors also had significantly superior recurrence-free survival at 1, 3, and 5 years (88%, 74%, and 67% vs 76%, 59%, and 51%, respectively; P = .002) and lower 5-year recurrence rates (8.8% vs 22%; P < .001) than patients with AFP-producing tumors. When stratified by radiologic Milan criteria, 5-year survival was better, and recurrence lowest, among patients with non-AFP-producing tumors within the Milan criteria (71% survival and 6% recurrence), and survival was worse, and recurrence highest, for patients with AFP-producing tumors outside the Milan criteria (40% survival and 42% recurrence; P < .001). Significant predictors of recurrence among patients with non-AFP-producing tumors include radiologic (>2 tumors [HR, 4.98; 95% CI, 1.72-14.4; P = .003]; cumulative diameter [1.70 per log SD; 1.12-2.59; P < .001]; outside the Milan criteria [10.0; 3.7-33.3; P < .001) and pathologic factors (>2 tumors [4.39; 1.32-14.6; P = .02]; cumulative diameter [2.32 per log SD; 1.43-3.77; P = .001]; microvascular [3.07; 1.02-9.24; P = .05] and macrovascular invasion [8.75; 2.15-35.6; P = .002]). Conclusions and Relevance: Nearly one-third of patients with radiographically apparent HCC have non-AFP-producing tumors that have more favorable pathologic characteristics, lower posttransplant recurrence, and superior survival compared with patients with AFP-producing tumors. Posttransplant HCC recurrence for patients with non AFP-producing tumors is predicted by important radiologic and pathologic factors, and is negligible for patients within the Milan criteria. Stratifying patients by AFP status in addition to radiological criteria may improve the selection process for and the prioritization of transplant candidates.

AB - Importance: Sustainable, capacity-building educational collaborations are essential to address the global burden of surgical disease. Objective: To assess an international, competency-based training paradigm for hernia surgery in underserved countries. Design, Setting, and Participants: In this prospective, observational study performed from November 1, 2013, through October 31, 2015, at 16 hospitals in Brazil, Ecuador, Haiti, Paraguay, and the Dominican Republic, surgeons completed initial training programs in hernia repair, underwent interval proficiency assessments, and were appointed regional trainers. Competency-based evaluations of technical proficiency were performed using the Operative Performance Rating Scale (OPRS). Maintenance of proficiency was evaluated by video assessments 6 months after training. Certified trainees received incentives to document independent surgical outcomes after training. Main Outcomes and Measures: An OPRS score of 3.0 (scale of 1 [poor] to 5 [excellent]) indicated proficiency. Secondary outcomes included initial vs final scores by country, scores among surgeons trained by the regional trainers (second-order trainees), interval scores 6 months after training, and postoperative complications. Results: A total of 20 surgeon trainers, 81 local surgeons, and 364 patients (343 adult, 21 pediatric) participated in the study (mean [SD] age, 47.5 [16.3] years; age range, 16-83 years). All 81 surgeons successfully completed the program, and all 364 patients received successful operations. Mean (SD) OPRS scores improved from 4.06 (0.87) before the initial training program to 4.52 (0.57) after training (P < .001). No significant variation was found by country in final scores. On trainee certification, 20 became regional trainers. The mean (SD) OPRS score among 53 second-order trainees was 4.34 (0.68). After 6-month intervals, the mean (SD) OPRS score among participating surgeons was 4.34 (0.55). The overall operative complication rate during training series was 1.1%. Conclusions and Relevance: Competency-based training helps address the global burden of surgical disease. The OPRS establishes an international standard of technical assessment. Additional studies of long-term surgeon trainer proficiency, community-specific quality initiatives, and expansion to other operations are warranted.

AB - Importance: Although frequently used in treating intensive care unit (ICU) patients with sepsis, empirical antifungal therapy, initiated for suspected fungal infection, has not been shown to improve outcome. Objective: To determine whether empirical micafungin reduces invasive fungal infection (IFI)-free survival at day 28. Design, Setting, and Participants: Multicenter double-blind placebo-controlled study of 260 nonneutropenic, nontransplanted, critically ill patients with ICU-acquired sepsis, multiple Candida colonization, multiple organ failure, exposed to broad-spectrum antibacterial agents, and enrolled between July 2012 and February 2015 in 19 French ICUs. Interventions: Empirical treatment with micafungin (100 mg, once daily, for 14 days) (n = 131) vs placebo (n = 129). Main Outcomes and Measures: The primary end point was survival without proven IFI 28 days after randomization. Key secondary end points included new proven fungal infections, survival at day 28 and day 90, organ failure, serum (1-3)-beta-D glucan level evolution, and incidence of ventilator-associated bacterial pneumonia. Results: Among 260 patients (mean age 63 years; 91 [35%] women), 251 (128, micafungin group; 123, placebo group) were included in the modified intent to-treat analysis. Median values were 8 for Sequential Organ Failure Assessment (SOFA) score, 3 for number of Candida-colonized sites, and 99 pg/mL for level of (1-3)-beta-D-glucan. On day 28, there were 82 (68%) patients in the micafungin group vs 79 (60.2%) in the placebo group who were alive and IFI free (hazard ratio [HR], 1.35 [95% CI, 0.87-2.08]). Results were similar among patients with a (1-3)-beta-D-glucan level of greater than 80 pg/mL (n = 175; HR, 1.41 [95% CI, 0.85-2.33]). Day-28 IFI-free survival in patients with a high SOFA score (>8) was not significantly different when compared between the micafungin vs placebo groups (HR, 1.69 [95% CI, 0.96-2.94]). Use of empirical micafungin decreased the rate of new invasive fungal infection in 4 of 128 patients (3%) in the micafungin group vs placebo (15/123 patients [12%]) (P = .008). Conclusions and Relevance: Among nonneutropenic critically ill patients with ICU-acquired sepsis, Candida species colonization at multiple sites, and multiple organ failure, empirical treatment with micafungin, compared with placebo, did not increase fungal infection-free survival at day 28.

AB - OBJECTIVES: We analyzed the work ability index (WAI) and its first item (work ability score, WAS) - and subsequent four-year changes thereof - as predictors of disability pension (DP). METHODS: We linked survey responses of 5251 Finnish municipal employees, aged 44-58 years, to pension and death register data until 2009. Job content (physical, mental, or mixed) was based on observation. Baseline (1981) WAI was divided into poor (<27), moderate (28-36), and good/excellent (>37) and WAS into poor (0-5), moderate (6-7), and good/excellent (8-10). Four year changes in these scores were classified as strong decline (=18.5-24.9 kg/m2; referent, OR 1.00). The odds of reporting PI were similar in underweight and class I obese women. Women were found to have greater odds than men of reporting PI in four of the five nondesirable BMI categories (P < 0.05). CONCLUSIONS: The within- and between-sex differences in the odds of reporting PI vary significantly by BMI category. Future research needs to include the underweight BMI category when investigating PI and sedentary time because of the potential clinical relevance.

PMID- 27706499 TI - Hormonal Contraceptives for Endometrial Cancer Prevention in Obese and High-Risk Women in Virginia. AB - OBJECTIVES: Endometrial cancer remains the fourth most common malignancy among US women, and hormonal contraceptives drastically reduce this risk. The study objectives were to assess the prescribing patterns, counseling practices, and knowledge of family physicians and obstetrician/gynecologists (OB/GYNs) regarding hormonal contraceptives, obesity, and cancer prevention. METHODS: A 25-question survey was mailed to 4600 OB/GYNs and family practitioners licensed in Virginia to assess self-reported hormonal contraceptive prescription practices, patient evaluation and counseling, and gynecologic oncology knowledge. chi2 and t tests were used to assess for differences across groups. P < 0.05 was deemed significant. RESULTS: In total, 392 (9%) surveys were returned, with 256 (6%) being complete for analysis. The mean physician age was 53.6 years, 50.2% were men, and 92.6% of physicians prescribed hormonal contraception. Most physicians recognized decreased endometrial cancer risk associated with oral contraceptive pills (73.0%) and increased risk with obesity (95.3%), but only 36.7% consistently counseled patients on obesity-associated cancer risk. Compared with family physicians, OB/GYNs were more likely to cite endometrial cancer prevention as an indication for hormonal contraceptives (53.3% vs 10.9%, P < 0.0001); more often counseled patients on obesity-related cancer risk (P = 0.003); and were more likely to correctly identify Lynch syndrome (69.4% vs 22.5%, P < 0.0001), diabetes mellitus (85.2% vs 38.8%, P < 0.0001), and hypertension (41.7% vs 10.1%, P < 0.0001) as risk factors for endometrial cancer. Endometrial or ovarian cancer prevention factored into <2% of total hormonal contraception prescriptions; however, OB/GYN physicians were more likely to prescribe for those indications than family physicians (P = 0.005 and P < 0.001, respectively). CONCLUSIONS: Family physicians and OB/GYNs could improve their knowledge of endometrial cancer risk factors and the use of hormonal contraception for chemoprevention. This represents a significant opportunity for both specialties to optimize primary endometrial cancer prevention in their increasingly obese and at-risk female patients. PMID- 27706500 TI - Pharmacogenomics Can Enhance Prescribing of Psychiatric Medications. AB - Many psychiatric patients experience pharmaceutical intolerances, and some of them do not derive optimal efficacy from their pharmacotherapies. Clinical problems such as these may result in prolonged dysfunction, adverse consequences, and repeated changes in medication treatment regimens. Pharmacogenomics is a laboratory method that aids individualized medication selection by predicting drug efficacy and adverse effect profiles. It is a technique that involves the testing of patients' genetic makeup to improve medicinal response and tolerance. Pharmacogenomics aims to clarify pharmacokinetics and pharmacodynamics in addition to focusing on hepatic cytochrome enzyme metabolism. Ultimately, it facilitates optimal selection and adjustment of medications to enhance clinical outcomes. Pharmacogenomics is most useful in cases in which routinely prescribed pharmacotherapies are either suboptimally effective or have unacceptable adverse effects. Once there has been a failure of a therapeutic drug treatment, rather than "blindly" selecting an alternative medicine, pharmacogenomic test results can provide guidance for the selection of the most appropriate drug and its dose. The intent is to yield a greater likelihood of patient success in following a therapeutic intervention. PMID- 27706502 TI - Diabetes Mellitus and the Skin: Recognition and Management of Cutaneous Manifestations. AB - Diabetes mellitus (DM) is a heterogeneous condition characterized by hyperglycemia as a consequence of defects in insulin secretion and variable degrees of insulin resistance. DM is the most common endocrine disorder in the United States, affecting 9.3% of the population (29.1 million people) in 2014. Skin disorders are present in 79.2% of patients with DM, and cutaneous disease may appear as the first sign of DM or develop at any time in the course of the disease. Given the increasing incidence and prevalence of DM in the United States, primary care physicians should be aware of the associated cutaneous manifestations. This clinical review provides a brief guide to primary care physicians for recognizing and managing skin conditions that they may encounter when caring for patients with DM. PMID- 27706501 TI - Frequency of Adverse Events Before, During, and After Hospital Admission. AB - OBJECTIVES: Adverse events (AEs) are unintended physical injuries resulting from or contributed to by medical or surgical care. We determined the frequency and type of AEs before, during, and after hospital admission. METHODS: We conducted a cohort study of 296 adult hospital patients. We used the standardized Institute for Healthcare Improvement Global Trigger Tool for Measuring Adverse Events to review the medical records of the hospital patients for occurrence, timing relative to hospital admission, severity, and preventability of AEs. We also identified the primary physiologic system affected by the AE. RESULTS: Among 296 patients, we identified 338 AEs. AEs occurred with similar frequency before (n = 148; 43.8%) and during hospital admission (n = 162; 47.9%). Fewer AEs occurred after discharge (n = 28; 8.3%). Half of all AEs (n = 169; 50.0%) were severe, whereas 47.9% (n = 162) were preventable. CONCLUSIONS: AEs occur with similar frequency before and during hospitalization and may contribute more to hospital admissions than previously recognized. These findings suggest that efforts to improve patient safety should include outpatient settings in addition to the more commonly targeted acute care settings.

AB - Allergies to various antibiotics are reported by a substantial proportion of patients. As a result, clinical decision support programming generates frequent warnings when prescribing within electronic medical records. For a variety of reasons, the majority of these warnings may be inappropriate. Our improved understanding of the underlying physiology of allergic processes reveals that the majority of cross-reacting antibiotic allergies are implausible. Appropriate history taking and workup can invalidate many more warnings. Electronic medical records ideally should permit documentation that would facilitate more accurate entry and eliminate similar future warnings.

AB - OBJECTIVE: The purpose of this study was to correlate the significance of bone marrow hemophagocytosis and analyze outcome data in patients with suspected hemophagocytic lymphohistiocytosis (HLH) at a tertiary care hospital during the course of 5 years. METHODS: The pathology database of State University of New York Upstate Medical University, Syracuse, was searched for the terms "hemophagocytosis," "hemophagocytic syndrome," and "hemophagocytic lymphohistiocytosis" encompassing the period January 2009-December 2014. Bone marrow aspirate and biopsy specimens, along with ancillary laboratory studies, clinical course, and outcome data, were reviewed for each case. RESULTS: Of the 23 patients included in our study, HLH was diagnosed in 14 (60.8%). Bone marrow hemophagocytosis (HPC) was seen in a higher proportion of patients (78.5%) who were diagnosed as having HLH; however, 55.5% of the patients who were not diagnosed as having HLH also showed evidence of bone marrow HPC. Patients with malignancy-associated HLH had a markedly worse outcome compared with patients with nonmalignancy-associated HLH. CONCLUSIONS: Although bone marrow HPC is fairly sensitive, it is not specific to establish a diagnosis of HLH. A high index of clinical suspicion together with early diagnosis and treatment is imperative to improve outcomes in patients suspected of having HLH.

PMID- 27706507 TI - Intravenous Thrombolysis Attenuates Neurologic Deterioration After Ischemic Stroke. AB - INTRODUCTION: Although intravenous tissue plasminogen activator (IV tPA) is associated with neurologic deterioration (ND) caused by hemorrhage, whether it attenuates deterioration as a result of other etiologies including progressive stroke remains unexplored. The objective of this study was to determine whether IV tPA is associated with a reduced risk of ND caused by progressive stroke. METHODS: A retrospective investigation of consecutively admitted patients with acute ischemic stroke (July 2008-June 2014) within 4.5 hours of symptom onset was conducted at a tertiary care center. Patients treated with IV tPA were compared with those who were not. The primary outcome was ND resulting from progressive infarction (a two-point increase in the National Institutes of Health Stroke Scale score during a 24-hour period). RESULTS: A total of 699 registry patients (median age 65 years, interquartile range 55-76, 48.4% women, 70.4% nonwhite) were included in the study, and 58.1% received IV tPA. In crude regression, IV tPA did not reduce the odds of ND caused by progressive infarction; however, IV tPA-treated patients were at a 55% lower odds of ND from any cause (odds ratio 0.45, 95% confidence interval 0.32-0.61, P < 0.001). After adjusting for covariates, IV tPA use remained strongly associated with a 39% lower odds of ND from any cause (odds ratio 0.61, 95% confidence interval 0.48-0.79, P < 0.001). CONCLUSIONS: Although IV tPA did not correlate with a reduced odds of progressive infarction, it was significantly associated with a lower odds of ND by any mechanism. PMID- 27706509 TI - Atrioventricular Accessory Pathways: Mechanisms, Electrocardiograms, and Associated Arrhythmias. AB - An atrioventricular accessory pathway (AP) may be manifest or concealed. When manifest, it leads to preexcitation on the baseline electrocardiogram, which is called the Wolff-Parkinson-White pattern. The degree of preexcitation varies according to the relative conduction speed of the atrioventricular node versus the AP, the AP location, and the AP refractory period. This explains that even a manifest AP may lead to only intermittent preexcitation. The AP conducts faster than the atrioventricular node but has a longer refractory period, which allows the initiation of a reentrant arrhythmia called atrioventricular reciprocating tachycardia. In addition to re-entry, a manifest AP may allow the fast antegrade conduction of an atrial tachyarrhythmia, leading to a small risk of sudden death; the latter depends on the AP refractory period (ie, the number of atrial waves it can conduct back to back) rather than the AP conduction speed. This can be assessed invasively and noninvasively and allows risk stratification of asymptomatic individuals. PMID- 27706510 TI - Unattended Sleep Studies in a VA Population: Initial Evaluation by Chart Review Versus Clinic Visit by a Midlevel Provider. AB - OBJECTIVES: Obstructive sleep apnea (OSA) is a prevalent disorder that is associated with multiple medical consequences. Although in-laboratory polysomnography is the gold standard for the diagnosis of OSA, portable monitors have been developed and studied to help increase efficiency and ease of diagnosis. We aimed to assess the adequacy of a midlevel provider specializing in sleep medicine to risk-stratify patients for OSA based on a chart review versus a comprehensive clinic evaluation before scheduling an unattended sleep study. METHODS: This study was an observational, nonrandomized, retrospective data collection by chart review of patients accrued prospectively who underwent an unattended sleep study at the Sleep Health Center at the Memphis Veterans Affairs Medical Center during the first 13 months of the program (May 1, 2011-May 31, 2012). A total of 205 patients were included in the data analysis. RESULTS: Analysis showed no statistically significant differences between chart review and clinic visit groups (P = 0.54) in terms of OSA diagnosis. Although not statistically significant, the analysis shows a trend toward higher mean age (50.3 vs 47.4 years; P = 0.10) and lower mean body mass index (34.4 vs 36.0; P = 0.08) in individuals who were evaluated during a comprehensive clinic visit. A statistically significant difference is seen in terms of the pretest clinical probability of OSA being moderate or high in 62.2% of patients in the clinic visit group and 95.7% in the chart review group, with a chi2P <= 0.0001. CONCLUSIONS: In the Veterans Health Administration's system, the assessment of pretest probability may be determined by a midlevel provider using chart review with equal efficacy to a comprehensive face-to-face evaluation in terms of OSA diagnosis via unattended sleep studies.

AB - Introduction The rapid response team (RRT) is a multidisciplinary team who evaluates hospitalized patients for concerns of nonemergent clinical deterioration. RRT evaluations are mandatory for children whose Pediatric Early Warning System (PEWS) score (assessment of child's behavior, cardiovascular and respiratory status) is >=4. We aimed to determine if there were differences in characteristics of RRT calls between children who were admitted primarily to either medical or surgical services. We hypothesized that RRT activations would be called for less severely ill children with lower PEWS score on surgical services compared with children admitted to a medical service. Materials and Methods We performed a retrospective review of all children with RRT activations between January 2008 and April 2015 at a tertiary care pediatric hospital. We evaluated the characteristics of RRT calls and made comparisons between RRT calls made for children admitted primarily to medical or surgical services. Results A total of 2,991 RRT activations were called, and 324 (11%) involved surgical patients. Surgical patients were older than medical patients (median: 7 vs. 4 years; p < 0.001). RRT evaluations were called for lower PEWS score in surgical patients compared with medical (median: 3 vs. 4, p < 0.001). Surgical patients were more likely to remain on the inpatient ward following the RRT (51 vs. 39%, p < 0.001) and were less likely to require an advanced airway than medical patients (0.9 vs. 2.1%; p = 0.412). RRT evaluations did not differ between day and night shifts (52% day vs. 48% night; p = 0.17). All surgical patients and all but one medical patient survived the event; surgical patients were more likely to survive to hospital discharge (97 vs. 91%, p < 0.001) Conclusions RRT activations are rare events among pediatric surgical patients. When compared with medical patients, RRT evaluation is requested for surgical patients with a lower PEWS score and these children are less likely to require transfer to a higher level of care, suggesting that pediatric surgery team, families, and nursing staff may not be as comfortable with clinical deterioration.

We aim to assess the agreement of three scores intending to predict the need for surgery and/or mortality in our patient cohort, and analyze agreement between the different scores. Methods This study is a retrospective analysis of patients with NEC Bell's stage II and III, managed in a single institution (1991-2011). Three existing scores (Metabolic Derangement Acuity score, NEC score, Detroit score) were calculated individually for each patient. The agreement between predicted outcome by scores and real outcome was evaluated with kappa statistic. Results Of 57 children, 46% presented with NEC stage II, 54% with stage III, 46% were treated with surgery, 54% conservatively, and survival was 58%. The kappa indexes for "need for surgery" were 0.41, 0.13, and 0.12 and kappa indexes for "mortality" were 0.27, 0.04, and 0.1 for the Metabolic Derangement Acuity score, the NEC score, and the Detroit score, respectively. Conclusion In our cohort, the agreement between the predicted outcomes by scores and the real need for surgery and/or mortality was poor. There was a lack of clinical usefulness of the tested scores. We must continue to better identify parameters to help guide the management of these patients.

AB - Background and study aim Leakage of the surgical suture is the main complication of laparoscopic sleeve gastrectomy (LSG) and is amenable to endoscopic therapy. The aim of this study was to evaluate the efficacy of a specifically designed self-expandable metal stent (SEMS) to seal the leakage. Patients and methods Over a 2-year period, patients referred for the treatment of post-LSG fistulas underwent placement of a fully covered esophagogastric SEMS with a specific design. Results A total of 10 patients were treated after a mean time of 50.9 days from the diagnosis of post-LSG leakage. A total of 11 SEMSs were placed. After stent removal, the leakage was seen to have healed in eight patients. Two patients who were treated with an SEMS with different mesh design, experienced stent migration, which required alternative endoscopic treatment such as the insertion of double-pigtail stents. After a mean follow-up period of 13.4 months, all patients were asymptomatic. Conclusions: Placement of a specifically designed SEMS for the treatment of post-LSG fistulas seems a promising first-line therapy according to this small series.

AB - Background and study aim: Endoscopic submucosal dissection (ESD) is currently the reference method to achieve an en bloc resection for large lesions; however, the technique is difficult and risky, with a long learning curve. In order to reduce the morbidity, training courses that use animal models are recommended. Recently, self-learning software has been developed to assist students in their training. The aim of this study was to evaluate the impact of this tool on the ESD learning curve. Methods: A prospective, randomized, comparative study enrolled 39 students who were experienced in interventional endoscopy. Each student was randomized to one of two groups and performed 30 ESDs of 30 mm standardized lesions in a bovine colon model. The software group used the self-learning software whereas the control group only observed an ESD procedure video. The primary outcome was the rate of successful ESD procedures, defined as complete en bloc resection without any perforation and performed in less than 75 minutes. Results: A total of 39 students performed 1170 ESDs. Success was achieved in 404 (70.9 %) in the software group and 367 (61.2 %) in the control group (P = 0.03). Among the successful procedures, there were no significant differences between the software and control groups in terms of perforation rate (22 [4.0 %] vs. 29 [5.1 %], respectively; P = 0.27) and mean (SD) procedure duration (34.1 [13.4] vs. 32.3 [14.0] minutes, respectively; P = 0.52). For the 30th procedure, the rate of complete resection was superior in the software group (84.2 %) compared with the control group (50.0 %; P = 0.01). Conclusion: ESD self-learning software was effective in improving the quality of resection compared with a standard teaching method using procedure videos. This result suggests the benefit of incorporating such software into teaching programs. PMID- 27706527 TI - Two-Stage Indicators to Assess Learning Curves for Minimally Invasive Ivor Lewis Esophagectomy. AB - BACKGROUND: Minimally invasive esophagectomy (MIE) Ivor Lewis has been increasingly performed over the last two decades. To guide the implementation of this technically demanding procedure, a comprehensive assessment of MIE-Ivor Lewis learning curves should include both the general competence to accomplish the procedure and the ability to generate oncological benefits. These objectives are believed to be associated with different phases of the learning curve. METHODS: A retrospective review of the first 109 patients who underwent MIE-Ivor Lewis by a single qualified surgeon was conducted. Relevant variables were collected and assessed by regression analysis to identify suitable indicators for patient stratification and learning curve assessment. Thereafter, the differential analysis was performed among groups to validate the learning curve model. RESULTS: Two variables, intrathoracic gastroesophageal anastomosis time and bilateral recurrent laryngeal nerve (RLN) lymphadenectomy number, which plateaued, respectively, after the 26th and 88th cases, were selected as meaningful indicators to identify different competence levels. Therefore, 109 patients were chronologically subcategorized into three groups (the first 26 MIEs as the early group, the next 62 cases as the middle group, and 21 most recent cases as the late group). Perioperative data were compared between groups with positive results to indicate a three-phase model for a learning curve for MIE Ivor Lewis. CONCLUSIONS: An MIE-Ivor Lewis learning curve should include three discrete phases that indicate, successively, unskilled operation (general competence to accomplish, less proficiency), surgical proficiency, and oncological efficacy. Intrathoracic anastomosis time and bilateral RLN lymphadenectomy were identified as suitable indicators delineate the different stages of an MIE-Ivor Lewis learning curve.

PMID- 27706529 TI - Antifungal Long-Chain Alkenyl Sulphates Isolated from Culture Broths of the Fungus Chaetopsina sp. AB - During a high-throughput screening program focused on the discovery and characterization of new antifungal compounds, a total of 8320 extracts from Fundacion MEDINA's collection were screened against a panel of 6 fungal parasitic strains, namely Candida glabrata, Candida krusei, Candida parapsilosis, Candida tropicalis, Candida albicans, and Aspergillus fumigatus. A total of 127 extracts displayed antifungal properties and, after LC/MS dereplication, 10 were selected for further fractionation. Bioassay-guided fractionation from a 1-L fermentation of one of these extracts, belonging to the fungus Chaetopsina sp., led to the isolation of linoleyl sulphate (1), linolenyl sulphate (2), and oleyl sulphate (3) as the compounds responsible for the antifungal activity. These molecules were previously described as synthetic products with the ability to produce the allosteric inhibition of soybean lipoxygenase and human lipoxygenase.

AB - Herpes simplex virus infections persist throughout the lifetime of the host and affect more than 80 % of the humans worldwide. The intensive use of available therapeutic drugs has led to undesirable effects, such as drug-resistant strains, prompting the search for new antiherpetic agents. Although diverse bioactivities have been identified in Schinus terebinthifolia, its antiviral activity has not attracted much attention. The present study evaluated the antiherpetic effects of a crude hydroethanolic extract from the stem bark of S. terebinthifolia against Herpes simplex virus type 1 in vitro and in vivo as well as its genotoxicity in bone marrow in mammals and established the chemical composition of the crude hydroethanolic extract based on liquid chromatography-diode array detector-mass spectrometry and MS/MS. The crude hydroethanolic extract inhibited all of the tested Herpes simplex virus type 1 strains in vitro and was effective in the attachment and penetration stages, and showed virucidal activity, which was confirmed by transmission electron microscopy. The micronucleus test showed that the crude hydroethanolic extract had no genotoxic effect at the concentrations tested. The crude hydroethanolic extract afforded protection against lesions that were caused by Herpes simplex virus type 1 in vivo. Liquid chromatography-diode array detector-mass spectrometry and MS/MS identified 25 substances, which are condensed tannins mainly produced by a B-type linkage and prodelphinidin and procyanidin units. PMID- 27706531 TI - Direct Oral Anticoagulants and Women. AB - Direct oral anticoagulants (DOACs) provide an effective, safe, and convenient therapeutic alternative to warfarin and other vitamin K antagonists (VKAs), and are now established for a wide range of indications. The use of DOACs in women merits special consideration due to two main situations: first, in relation to fertility, pregnancy, and lactation in women of reproductive age; second, because of their bleeding risk, leading to abnormal uterine and/or other genital tract bleeding. This review focuses on these two clinical situations, including approaches to management in the context of available information. PMID- 27706532 TI - Optimal Anticoagulation for Pregnant Women with Mechanical Heart Valves. AB - The prothrombotic state of pregnancy increases the risk of thromboembolic complications and death in women with mechanical heart valves (MHVs). Although it is accepted that these women must be on therapeutic anticoagulation throughout pregnancy, competing maternal and fetal risks, as well as the lack of high quality data from prospective studies, make the choice of the optimal method of anticoagulation challenging. Vitamin K antagonists (VKAs) are associated with fewer maternal complications, but conversely also the lowest live birth rates as well as warfarin-related embryopathy and fetopathy. Low-molecular-weight heparin (LMWH) does not cross the placenta and is associated with fewer fetal risks but more maternal complications. Sequential treatment involving VKAs in the second and third trimesters and either low-molecular-weight or unfractionated heparin in the first trimester, although appealing is still associated with maternal complications, especially around the time of bridging. As absolute equipoise of maternal versus fetal wellbeing is unlikely, patient preferences should be considered in decision making. A multidisciplinary team including hematologists, cardiologists, obstetric physicians, and high-risk obstetricians with expertise in the management of pregnant women with cardiac disease is required to optimize outcomes. Prospective studies are needed to determine the anticoagulant regimen for women with MHVs that provides optimal and acceptable maternal and fetal outcomes.

AB - Neonates form a unique cohort with distinct features associated with the hemostatic system compared with older children and adults. The development of the human hemostatic system begins around 10 weeks in utero and continues to evolve during childhood. This dynamic period termed developmental hemostasis should be taken into consideration when diagnosing a neonate with disorders of bleeding or thrombosis. PMID- 27706534 TI - Topical Tranexamic Acid in Total Knee Arthroplasty Patients with Increased Thromboembolic Risk. AB - The purpose of this study was to evaluate the efficacy and safety profiles of topical tranexamic acid (TXA) in patients undergoing elective total knee arthroplasty (TKA) with comorbid conditions precluding them from intravenous (IV) TXA use. A total of 104 patients were divided into two groups: 47 in the normal risk group and 57 in the high-risk group, with the latter representing those with one or more risk factors for venous thromboembolism (VTE). Demographics were similar between groups, and there were no differences with regard to postoperative changes in hemoglobin (- 3.42 g/dL +/- 1.07 and - 3.68 g/dL +/- 1.07, p = 0.214), total drain output (630.2 mL +/- 331.6 and 566.9 mL +/- 343.9, p = 0.344), postoperative transfusion rate (2.1 and 3.5%, p = 0.675), or total number of complications 3 (6.5%) and 5 (8.8%) for the normal- and high-risk groups, respectively (p = 0.671). Topical TXA exhibited a similar safety and efficacy profile in reducing postoperative blood loss in a group of patients at increased thromboembolic risk, without a significant increase in complications or thromboembolic events. Topical TXA appears to represent a safe and efficacious alternative to IV TXA in patients at high risk for VTE undergoing TKA. PMID- 27706536 TI - [Historical Development of the Wool and Colour Plate Tests for Screening for Colour Vision Deficiencies in German Speaking Countries]. AB - Colour vision is a complex visual function that can be affected by congenital and/or acquired disorders. The frequency of congenital colour vision deficiencies has been investigated in rail and navy staff since the 1870s. Various test methods have been developed. Wool tests, flor contrast tests and colour plate tests have been used. A published colour plate test, based on Stilling's pseudo isochromatic plates in combination with a flor contrast test, has been a common screening method for colour vision testing in German-speaking countries. This test is intended to detect congenital and acquired colour vision deficiencies in a simple and safe manner. More modern options, such as Internet and tablet PC have technical limitations, but will increasingly be used for screening for colour vision deficiencies. PMID- 27706535 TI - [Finite Element Modelling of the Eye for the Investigation of Accommodation]. AB - Background: Accommodation research increasingly uses engineering methods. This article presents the use of the finite element method in accommodation research. Material and Methods: Geometry, material data and boundary conditions are prerequisites for the application of the finite element method. Published data on geometry and materials are reviewed. It is shown how boundary conditions are important and how they influence the results. Results: Two dimensional and three dimensional models of the anterior chamber of the eye are presented. With simple two dimensional models, it is shown that realistic results for the accommodation amplitude can always be achieved. More complex three dimensional models of the accommodation mechanism - including the ciliary muscle - require further investigations of the material data and of the morphology of the ciliary muscle, if they are to achieve realistic results for accommodation. Discussion and Conclusion: The efficiency and the limitations of the finite element method are especially clear for accommodation. Application of the method requires extensive preparation, including acquisition of geometric and material data and experimental validation. However, a validated model can be used as a basis for parametric studies, by systematically varying material data and geometric dimensions. This allows systematic investigation of how essential input parameters influence the results. PMID- 27706537 TI - Colorectal anastomotic dehiscence: an endoscopic modified-stent solution.

AB - High levels of mental disorders, especially PTSD, are commonly known among groups of people forced to leave their homeland as a consequence of war-related experiences (e. g. armed conflict, torture or persecution). Depending on the cultural background the perceptions of illnesses vary, different symptom presentation and thereupon different coping strategies respectively expectations towards health care services exist. To minimize the danger of misdiagnosis by different experts working with refugees in the host countries, a culture sensitive diagnostic approach is needed from the beginning. This article describes important aspects of culture-sensitive diagnostics by means of 2 commented case reports. Special focus is set on the aspect of linguistic and in a broader sense cultural comprehension between therapist, client and if necessary language mediator. PMID- 27706545 TI - Rescue therapy of a refractory rectal variceal bleeding in a cirrhotic patient by Linton-Nachlas tube and TIPS implantation in combination with variceal embolization. AB - Background Transjugular intrahepatic portosystemic shunt (TIPS) is considered the gold standard for treatment of gastrointestinal variceal bleeding refractory to endoscopic therapy in patients with portal hypertension. Clinically relevant hemorrhage from rectal varices is less frequent than from other sources, and the therapeutic role of TIPS is still ambiguous. Case report A 57-year-old female patient was referred to us in December 2015 with severe signs of decompensated alcohol-induced liver cirrhosis. During hospitalization, she presented with recurrent hematochezia from rectal varices following electrosurgical snare removal of a rectal adenoma. Endoscopic treatment with hemoclips, epinephrine and fibrin glue injections, and thermocoagulation failed to permanently stop the bleeding. Recurrent hemorrhage led to a further deterioration of liver function and clinical status of the patient. After a total of 3 endoscopic treatment attempts, hemostasis was achieved by transanal placement of a Linton-Nachlas balloon tube. Additionally, TIPS implantation with embolization of the rectal varices was performed successfully 24 hours after tube insertion, resulting in reduction of the portosystemic pressure gradient from 24 to 12 mmHg. Subsequently, the patient recovered clinically, hemopressin and catecholamine treatment was discontinued, and liver function test as well as serum hemoglobin levels improved. No further blood transfusions were required. Conclusion In this patient, rescue therapy with balloon compression and TIPS implantation in combination with variceal embolization in a cirrhotic patient with refractory rectal variceal bleeding was effective. To our knowledge, it is the first description of this specific therapeutic approach. PMID- 27706546 TI - A liver nodule in a patient transplanted for primary sclerosing cholangitis: an interdisciplinary diagnostic approach. AB - We report the case of a 53-year-old female patient who was transplanted with the liver of a 71-year-old male donor for advanced primary sclerosing cholangitis (PSC) and who additionally was diagnosed with a histologically non-classifiable colitis shortly before transplantation. Upon follow-up abdominal ultrasound 4 months after transplantation, a liver lesion measuring 16 * 23 mm was detected in the transplanted liver. This lesion had not been noticed immediately after transplantation and showed a pattern suspicious for malignancy in contrast enhanced ultrasound. In line, a biopsy revealed the presence of a metastasis of an adenocarcinoma of colorectal origin, suggesting that a colitis- and PSC associated colorectal cancer of the recipient might have been overseen upon the initial diagnostic workup. Despite two negative follow-up colonoscopies, this hypothesis was further supported by a strong positive signal in projection to the cecum in a subsequently performed PET/CT-scan. However, surgical resection of the right colon that was performed simultaneously with the atypical resection of the liver metastasis only revealed an inflamed diverticulum but no malignancy in the resected colon segment. Moreover, cytogenetic and molecular genetic testing on the resected specimens clearly attributed the metastasis to the male donor. On the one hand, this case underlines the necessity of endoscopic surveillance of patients with PSC and/or inflammatory bowel disease as well as the challenges in diagnosis of colitis-associated cancer. On the other hand, it shows that the acceptance of organs from elderly donors in times of organ shortage might be linked to an increased risk of donor transmitted malignancies. PMID- 27706547 TI - [Percutaneous paraumbilical embolization of bleeding rectal varices due to portal hypertension]. AB - Introduction Portal hypertension may lead to severe esophageal or rectal variceal bleeding. Case report We present a case of a 67-year-old patient presenting with recurrent rectal variceal bleeding who was non-responsive to endoscopic treatment. We are reporting on an interventional therapeutic approach found in interdisciplinary consensus. Discussion Endoscopy, surgery or TIPS (transjugular intrahepatic portosystemic shunt) can be performed in patients with gastrointestinal bleeding due to portal hypertension in liver cirrhosis. In cases not suitable for these treatment options, or in cases where these failed to stop the bleeding, radiological percutaneous paraumbilical coil embolization of the portal vein collateral feeding the bleeding could be performed. In our case, as well as in published cases with embolization of jejunal or esophageal hemorrhage, complete stopping of the bleeding could be achieved without further treatment or re-bleeding. PMID- 27706548 TI - Continued Sex-Differences in the Rate and Severity of Knee Injuries among Collegiate Soccer Players: The NCAA Injury Surveillance System, 2004-2009. AB - We extend previous analyses and examined sex-differences in the rate and severity of knee injuries among collegiate soccer players between 2004 and 2009. Data from the National Collegiate Athletic Association Injury Surveillance System (NCAA ISS) were used to calculate injury incidence density (ID) per 1 000 athletic exposures (AE). Multivariable regression modeling then tested the relation between sex and knee injury incidence and severity among all injured soccer players, while controlling for contact, setting, and division level, as well as for the interactions among these variables. The rate of knee injuries was 1.19 per 1 000 AEs in women and 0.91 per 1 000 AEs in men (RR=1.31, 95% Wald CI=[1.16, 1.47]). In the multivariable modeling, women continued to experience significantly higher odds of knee injury compared with men (aOR=1.44, 95% CI=[1.27,1.63]). Also, the adjusted odds of a knee injury that resulted in surgery remained higher in women compared with men (aOR=1.61 (1.00, 2.58), as well as the amount of time lost from participation (beta=0.129; p=0.05). Given the prominence of soccer play in the United States, continued efforts to evaluate and improve knee injury prevention practices and policies may be especially important for female players. PMID- 27706549 TI - A Multivariate Assessment of Clinical Contributions to the Severity of Perceived Dysfunction Measured by the Cumberland Ankle Instability Tool. AB - Chronic ankle instability is a common pathological consequence of ankle sprains. However, screening tools which assess self-reported dysfunction offer little insight into clinical factors which may be useful to improve deficits. The purpose of this study was to identify factors that contribute most to self reported dysfunction. 93 individuals completed the Cumberland Ankle Instability Tool (CAIT), active range of motion, dynamic postural stability assessments, and an arthrometer inversion stress test to assess lateral ankle laxity and stiffness. Backwards selection linear-regression was used to identify the most parsimonious multifactorial model of the predictor variables' ability to predict questionnaire score. Ankle sprain history, dorsiflexion in knee flexion, medial lateral dynamic postural stability, and inversion laxity talar tilt had the highest relationships with the CAIT. When combined in the backwards-regression model index, these predictors explained approximately 57% of the variability (r=0.76, R2=0.57, F=27.49, p<0.001) of the CAIT. Previous history, laxity, range of motion restrictions and balance together contributed to account for almost 60% of the variability in the CAIT. Clinical measures may have prognostic value assessing the severity of chronic ankle instability and allow clinicians to focus on specific deficiencies during rehabilitation programs. PMID- 27706550 TI - Precooling does not Enhance the Effect on Performance of Midcooling with Ice Slush/Menthol. AB - This study investigated whether the combination of internal precooling (PC) and internal midcooling (MC cooling during exercise) would enhance performance more than MC alone. 9 trained males completed two 30-km cycling trials in a hot and humid environment (WBGT: 29+/-0.7 degrees C, 80+/-0.02% relative humidity). For 30 min before exercise, the subjects sat quietly and drank water at 23 degrees C (MC) or 3 degrees C (PC+MC). During the MC and PC+MC time trials, they drank an ice-slush/menthol beverage (i. e., 0.025% menthol). Trial time, gastrointestinal temperature (Tco ), heart rate (HR), rating of perceived exertion (RPE), thermal sensation (TS), and thermal comfort (TC) were assessed. Trial time was not significantly different (P>0.05) between MC and PC+MC (3 737+/-552 s and 3 815+/ 455 s). Before exercise, Tco was lower with precooling (37.0+/-0.3 degrees C; P<0.02). During exercise, no between-trial differences were noted for Tco, HR, RPE, TC or TS, but RPE was significantly lower with PC+MC in the latter stages (P<0.05). (1) Cold beverage intake before exercise did not improve the subsequent exercise performance with ice-slush/menthol beverage intake, and (2) despite no improvement in performance, RPE declined in the latter stages of exercise in the condition of PC+MC, suggesting that this combination might be beneficial for longer exercise. PMID- 27706551 TI - Traditional Periodization versus Optimum Training Load Applied to Soccer Players: Effects on Neuromuscular Abilities. AB - It is unknown whether traditional periodization of strength-power training involving accumulation, transformation and realization blocks is superior to other simpler and more practical training schemes. The purpose of this study was thus to investigate changes in strength/power/speed characteristics of elite soccer players in response to either classic strength-power periodization (TSP) or optimum power load (OPL). 23 professional soccer players were randomly assigned to TSP or OPL for 6 weeks in-season regular training (3 times per week). TSP involved half squats or jump squats, depending on the respective training block, while OPL involved only jump squats at the optimum power load. Results revealed that both groups presented similar significant (P<0.05) improvements in squat one repetition maximum, squat and countermovement jump heights and change of direction speed. In addition, although both groups reported significant increases in sprinting speed (P<0.05); delta change scores demonstrated a superior effect of OPL to improve 10- and 20-m speed. Similarly, OPL presented greater delta change in mean propulsive power in the jump squat. Therefore, training continuously at the optimum power zone resulted in superior performance improvements compared to training under classic strength-power periodization.

PMID- 27706553 TI - Association between aldehyde dehydrogenase 2 (ALDH2) Glu504Lys polymorphism and susceptibility to colorectal cancer: a meta-analysis. AB - Numerous studies have evaluated the association between Glu504Lys polymorphism in the aldehyde dehydrogenase 2 (ALDH2) gene and colorectal cancer (CRC) risk. However, the specific association remains controversial. To assess the relationship between the ALDH2 Glu504Lys polymorphism and CRC, we conducted a comprehensive meta-analysis of five case-control studies comprising 1664 patients with CRC and 2777 controls. The results of this meta-analysis showed that the ALDH2 Glu504Lys polymorphism was associated with a significantly reduced risk of CRC [Lys/Lys vs Glu/Glu: odds ratio (OR) = 0.95, 95% confidence interval (CI) = 0.58-1.54; Glu/Lys vs Glu/Glu: OR = 0.85, 95%CI = 0.75-0.97; dominant model: OR = 0.86, 95%CI = 0.76-0.98; recessive model: OR = 1.00, 95%CI = 0.62-1.61]. No significant heterogeneity or publication bias was observed in our meta-analysis. Based on the statistical data, our meta-analysis indicates that the ALDH2 Glu504Lys polymorphism is associated with reduced risk of developing CRC. PMID- 27706554 TI - Upregulation of ICAM-1 and IL-1beta protein expression promotes lung injury in chronic obstructive pulmonary disease. AB - Chronic obstructive pulmonary disease (COPD) is a devastating lung disorder characterized by sustained airway flow restriction that is not fully reversible. The precise pathogenic mechanisms are unknown, but it is clear that cigarette smoking and chronic inflammatory stimulation are the major causes of COPD. Lung inflammation associated with COPD involves multiple cytokines, aggregation, and activation of neutrophils in the airway and lung tissue, and release of proteases and oxygen free radicals. In this study, a rat model of COPD was established by daily cigarette smoke exposure plus endotoxin treatment (the experimental group). Respiratory curves were recorded by the BL-420 biological signal collecting and processing system. Furthermore, the contents of inflammatory mediators, intercellular adhesion molecular (ICAM)-1 and interleukin (IL)-1beta, in bronchoalveolar lavage fluid (BALF) were determined by enzyme linked immunosorbent assay for experimental, smoke-exposed only (control), and untreated (blank) rat groups. Protein expression levels of ICAM-1 and IL-1beta in the lung tissue were also compared among groups by the immunohistochemical streptavidin peroxidase method. The COPD model rats exhibited severe dyspnea and lung inflammation as evidenced by significantly prolonged expiratory duration, higher respiratory rate, elevated ICAM-1 and IL-1beta in BALF, and higher ICAM-1 and IL 1beta protein expression in lung tissue compared to control and blank group rats. Chronic cigarette smoke exposure plus endotoxin is a feasible and reliable model of COPD that recapitulates many clinical signs and pathogenic responses. ICAM-1 and IL-1beta upregulation are possible early contributors to COPD-associated inflammatory lung injury. PMID- 27706555 TI - Expression and clinical significance of the obesity-related gene TNFAIP9 in obese children. AB - To investigate the expression of tumor necrosis factor-alpha inducible protein 9 (TNFAIP9) gene in obese children and its clinical significance, 36 simple obese children and 17 non-obese children were recruited as research subjects. The adipose tissue was obtained by abdominal operation. The expression of TNFAIP9 was detected using real-time fluorescence quantitative polymerase chain reaction and western blot. The relationship between the expression of TNFAIP9 and blood lipid, blood glucose, and obesity indexes was analyzed. The levels of TNFAIP9 mRNA and protein in obese children were significantly lower than those in the control group (P < 0.05). The waist circumference (wc), body mass, body mass index (BMI), fat, total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), insulin resistance index (HOMA-IR), and endothelin (ET) in obese children were significantly higher than those in the control group. The level of high-density lipoprotein cholesterol (HDL-C) was significantly lower than that in the control group (P < 0.05). The level of TNFAIP9 protein was negatively correlated with the wc, body mass, BMI, fat, TC, TG, LDL-C, HOMA-IR, and ET (P < 0.05) and was positively correlated with the level of HDL-C (P < 0.05). In conclusion, the expression of TNFAIP9 significantly decreased in the adipose tissue of obese children, and its levels are closely related to blood lipid level, insulin resistance, and obesity. PMID- 27706556 TI - Developmental expression of LTbetaR and differential expression in Escherichia coli F18 resistant/sensitive piglets. AB - We analyzed LTbetaR mRNA expression in piglets from birth to weaning and compared the differential expression between Escherichia coli F18-resistant and sensitive populations to determine whether this gene could be used as a genetic marker for E. coli F18 resistance. Sutai piglets of different age groups (8, 18, 30, and 35 days; N = 4 each) and piglets demonstrating resistance/sensitivity to E. coli F18 were used. LTbetaR expression levels were determined by real-time PCR. The LTbetaR expression levels in the lymph node, duodenum, and jejunum were significantly higher in 8-day-old piglets than in the other age groups (P < 0.01), and the expression levels were significantly higher in the lungs of 8-day old piglets than in 35-day-old piglets (P < 0.01) and 30 day-old piglets (P < 0.05). In liver tissue, the expression level was significantly higher in the 35 day-old piglets than in other age groups (P < 0.01). In the stomach tissue, the expression level was significantly higher in 35-day-old piglets than in 18-day old piglets (P < 0.05). LTbetaR expression in the lymph nodes was significantly higher in the resistant group than in the sensitive group (P < 0.01), but there was no significant difference in the other tissues (P > 0.05). These results indicate that 8 days after birth is a crucial stage in the formation of mesentery lymph nodes and immune barriers in pigs, and increased expression of LTbetaR may be beneficial for developing resistance to E. coli F18.

Its seeds are rich in calories and proteins, and possess great potential for commercialization. Little is known about the genetic variability in the germplasm of most Lecythis species. Here, 11 inter-simple sequence repeat primers were used to estimate the genetic variability among 17 accessions, and to determine the levels of genetic variation and the standards of population structure in sapucaia. The accessions were obtained from the active germplasm bank (AGB) of Embrapa Meio-Norte, Teresina, PI, Brazil, and corresponded to four occurrence areas. Ninety-six loci were analyzed among the studied individuals. High variation was found at the species level, where the percentage of polymorphic bands was 94.79%, Nei's genetic diversity (h) was 0.3110, and Shannon's index (I) was 0.4732. In the analyzed populations, the percentage polymorphism ranged from 20.83 to 94.79%, Nei's genetic diversity ranged from 0.0863 to 0.2969, and Shannon's index ranged from 0.1260 to 0.4457. Significant genetic differentiation was detected among the populations (PhiST = 10.66%); however, the greatest genetic differentiation was found within the populations (89.34%), between which there was an intermediate level of gene flow (Nm = 1.10). Accessions BGS 2 and BGS 4 were the most divergent, whereas accessions BGS 14 and BGS 15 were the most similar. Therefore, sapucaia analyzed from the AGB present an elevated level of genetic diversity and may have potential use in genetic breeding programs.

AB - Tobacco is an economically important crop, and its potassium content can greatly affect the quality of tobacco leaves. However, the molecular mechanism involved in potassium starvation in tobacco has not been elucidated to date. In this study, Illumina (Solexa) sequencing technology was used to analyze the transcriptome of tobacco seedlings under low-potassium stress for 6, 12, and 24 h. After analysis, 107,824 assembled unigenes were categorized into 57 GO functional groups, and 31,379 unigenes (29.08%) were clustered into 25 COG categories. A total of 9945 genes were classified into 233 KEGG pathways, and 15,209 SSRs were found among the 107,824 unigenes. Between the two samples, 1034 genes were differentially expressed. Twelve randomly selected gene expression levels were analyzed by quantitative RT-PCR, and the results were highly consistent with those obtained by Solexa sequencing. Our results provide a comprehensive analysis of the gene-regulatory network of tobacco seedlings under low-potassium stress.

This study assessed the antibiotic susceptibility profile, the presence of the genetic marker blaOXA-23, and the clonal relationship among 34 nosocomial isolates of Acinetobacter spp obtained at a hospital in southeastern Brazil. Antibiotic sensitivity analysis was performed by the standard disc-diffusion method. All isolates were found to be extensively resistant to several drugs, but sensitive to polymyxin B. A polymerase chain reaction (PCR) assay was used to detect the blaOXA-23 gene, which is associated with carbapenem resistance. The genetic profile and the clonal relationship among isolates were analyzed via enterobacterial repetitive intergenic consensus (ERIC) PCR. The Acinetobacter spp were divided into four groups with 22 distinct genetic subgroups. ERIC-PCR analysis revealed the genetic diversity among isolates, which, despite having a heterogeneous profile, displayed 100% clonality among 56% (19/34) of them.

AB - In Brazil, canine hepatozoonosis is a tick-borne subclinical hemoparasitosis caused by a protozoa Hepatozoon canis and is highly prevalent in dogs in rural areas. An epizootiological study was conducted to investigate the prevalence of H. canis in the canine population of Itubera, Bahia, and to analyze any associated risk factors. Blood samples were collected from 380 dogs and determined the presence of the protozoan by performing capillary blood smear and polymerase chain reaction (PCR). Epizootiological data were collected by asking dog owners to answer a structured questionnaire. H. canis gamonts were not detected in the blood smears. However, PCR detected H. canis in 163/380 (42.9%) dogs examined. Physical examination and anamnesis indicated 105 (64.4%) positive asymptomatic dogs. Hematological alterations were observed in 115 (70.5%) infected dogs. No clinical, hematological, or epizootiological variable was found to be significantly associated to the infection. In conclusion, the high prevalence of H. canis infection in local dogs may be because of the peri-urban features of this municipality. Moreover, to the best of our knowledge, this study the first study to report H. canis infection in the State of Bahia.

AB - Piglet diarrhea is one of the primary factors that affects the benefits of the swine industry. Recent studies have shown that exon 2 of the swine leukocyte antigen-DQA gene is associated with piglet resistance to diarrhea; however, the contributions of additional exon coding regions of this gene remain unclear. Here, we detected and sequenced variants in the exon 3 region and examined their associations with diarrhea infection in 425 suckling piglets using the polymerase chain reaction-single-strand conformational polymorphism and sequencing analysis. The results revealed that exon 3 of the swine leukocyte antigen-DQA gene is highly polymorphic and pivotal to both diarrhea susceptibility and resistance in piglets. We identified 14 genotypes (AA, AB, BB, BC, CC, EE, EF, BE, BF, CF, DD, DH, GG, and GF) and eight alleles (A-H) that were generated by 14 nucleotide variants, eight of which were novel, and three nucleotide deletions. Statistical analyses revealed that the genotypes AB and EF were associated with resistance to diarrheal disease (P < 0.05), and the genotype DD may contribute to diarrhea susceptibility but was unique to Large White pigs (P > 0.05). These results elucidate the genetic and immunological background to piglet diarrhea, and provide useful information for resistance breeding programs. PMID- 27706562 TI - Prevalence of mutations in LEP, LEPR, and MC4R genes in individuals with severe obesity. AB - Obesity is a major public health concern; despite evidence of high heritability, the genetic causes of obesity remain unclear. In this study, we assessed the presence of mutations in three genes involved in the hypothalamic leptin melanocortin regulation pathway (leptin, LEP; leptin receptor, LEPR; and melanocortin-4 receptor, MC4R), which is important for energy homeostasis in the body, in a group of patients with severe obesity. For this study, we selected 77 patients who had undergone bariatric surgery and had a pre-operative body mass index (BMI) >35 kg/m2, early onset and a family history of being overweight. Candidate genes were screened by direct sequence analysis to search for rare genetic variations. The common LEP -2548 G/A polymorphism was also evaluated for its influence on the BMI (in obesity patients) and for obesity risk, using a case control study involving 117 healthy individuals. Two different non-synonymous alterations in MC4R were found in two patients: the p.(Thr112Met), previously described in the literature as a probable gene involved in the obesity phenotype, and the novel p.(Tyr302Asp) variant, predicted to be pathogenic by in silico evaluations and family segregation studies. The LEP -2548 G/A polymorphism was not associated with the BMI or obesity risk. In conclusion, we have reported a novel mutation in MC4R in a family of Italian patients with severe obesity. Screening for MC4R could be important for directing the carriers of mutations towards therapy including partial agonists of the MC4R that could normalize their appetite and inhibit compulsive eating. Next-generation sequencing could be used to clarify the genetic basis of obesity in the future. PMID- 27706563 TI - Characterization of the complete mitochondrial genome of Portunus pelagicus with implications for phylogenomics. AB - This study determined the mitochondrial genome structure of the blue swimming crab (Portunus pelagicus), and elucidated its phylogenetic relationships among the species within the order Decapoda. The complete mitochondrial genome was 16,155 bp long, and contained 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 DNA control region. The gene order of the genome was the same as that found within the family Portunidae. Twenty-three genes were on the heavy strand and 14 were on the light strand. Almost all of the protein coding genes were initiated by an ATG codon, except for three genes (ATP6, ND1, and ND3) that started with a rare ATT codon. Of the 13 protein-coding genes, 10 ended with complete TAA or TAG stop codons and three ended with an incomplete T codon. Thirteen non-coding regions were identified that ranged from 1 to 30 bp in length. Nine overlaps were found, which ranged 1 to 7 bp in length. Phylogenetic analyses based on 12 concatenated protein-coding genes revealed that P. pelagicus formed a monophyletic group with Portunus trituberculatus, which were in a larger group with Callinectes sapidus, while the genera Charybdis and Thalamita formed another group. These two groups clustered together and grouped with the genus Scylla. The phylogenetic analysis supported the inclusion of Charybdis in subfamily Portuninae of the family Portunidae, and revealed a close relationship between Charybdis and Thalamita. We suggest that Thalamita should also be classified into the subfamily Portuninae. The results can be used in the study of phylogenetic, population genetic and conservation genetics of P. pelagicus. PMID- 27706564 TI - Inclusion of cytoplasmic lineage effect and direct-maternal genetic covariance for genetic evaluation of growth traits in Nellore cattle. AB - We evaluated the impact of cytoplasmic lineage effects (Lc) for growth traits on genetic evaluation, including the genetic covariance between direct and maternal effects (sigmaam). Pedigree data from 496,190 Nellore animals and observations on birth weight (BW, N = 243,391), weaning weight (WW, N = 431,681), and post weaning weight gain adjusted to 345 days (PWG, N = 172,131) were analyzed. Four univariate models were used to obtain estimates of (co)variance components using the restricted maximum likelihood method in the BLUPF90 program. Model 1 included Lc and sigmaam. Model 2 included Lc and sigmaam was set to zero. Model 3 did not include Lc. Model 4 did not include Lc and sigmaam was set to zero. These models considered the effects of the Lc as random. Phenotypic variance obtained through cytoplasmic lineage effects was determined for all traits, ranging from 0.07 to 0.15, 0.15 to 0.03, and 0.05 to 0.03% for BW, WW, and PWG, respectively, for models 1 and 2. Correlations between direct and maternal genetic components were positive for WW and negative for BW and PWG. No differences were observed for genetic parameter estimates or animal ranking with the inclusion of sigmaam. For BW, the likelihood ratio suggested that model 1 best fits the data, while model 4 was the most appropriate for WW and PWG. Thus, these models are recommended for genetic evaluations. Despite the low magnitude of cytoplasmic lineages, this effect could predict breeding value and improve the selection of animals for BW in this Nellore population. PMID- 27706565 TI - Mixed models for selection of Jatropha progenies with high adaptability and yield stability in Brazilian regions. AB - The aim of this study was to estimate genetic parameters via mixed models and simultaneously to select Jatropha progenies grown in three regions of Brazil that meet high adaptability and stability. From a previous phenotypic selection, three progeny tests were installed in 2008 in the municipalities of Planaltina-DF (Midwest), Nova Porteirinha-MG (Southeast), and Pelotas-RS (South). We evaluated 18 families of half-sib in a randomized block design with three replications. Genetic parameters were estimated using restricted maximum likelihood/best linear unbiased prediction. Selection was based on the harmonic mean of the relative performance of genetic values method in three strategies considering: 1) performance in each environment (with interaction effect); 2) performance in each environment (with interaction effect); and 3) simultaneous selection for grain yield, stability and adaptability. Accuracy obtained (91%) reveals excellent experimental quality and consequently safety and credibility in the selection of superior progenies for grain yield. The gain with the selection of the best five progenies was more than 20%, regardless of the selection strategy. Thus, based on the three selection strategies used in this study, the progenies 4, 11, and 3 (selected in all environments and the mean environment and by adaptability and phenotypic stability methods) are the most suitable for growing in the three regions evaluated. PMID- 27706566 TI - Estimation of genetic parameters and genetic changes for growth characteristics of Santa Ines sheep. AB - Studying genetic parameters and genetic changes in Santa Ines sheep is important, because it is the commonest breed in Brazil. This study obtained genetic data from 37,735 pedigree records of lambs over 12 years (2003-2014) from 33 flocks in 10 Brazilian States; 11,851 records of performance were available. (Co)variance components, genetic parameters and breeding values estimates were obtained by derivative-free restricted maximum likelihood in a univariate analysis that included maternal additive genetic and maternal permanent environmental effects. Birth weight, weaning weight, weight at 180 days of age, weight at 270 days of age, average daily weight gain in the following states: from birth to weaning, from weaning to 6 months, from 6 months to 9 months, and from weaning to 9 months; presence of hair in fur and leg muscularity were assessed. (Co)variance component values increased in the weight traits with age. A significant maternal effect was found in the pre-weaned stage that decreased in the post-weaned stage. High values were estimated for the maternal permanent environmental effect, possibly because of the extensive grassland that was available. High total heritability values were estimated for all of the traits evaluated. Significant, positive correlations were found between direct and maternal additive genetic traits with a gradual decrease as the lambs gained independence from their mothers. The genetic trends observed were irregular and incremental. Significant genetic variance suggests that direct selection for pre-weaning traits results in indirect selection of maternal abilities, and individual selection of any post weaning trait results in rapid genetic improvement. PMID- 27706567 TI - Cinnamon effectively inhibits the activity of leukemia stem cells. AB - Cinnamon is the main component of Sanyangxuedai, which is one of the effective traditional Chinese medicines for treating malignancies. Leukemia is a prevalent malignant disease that Sanyangxuedai has been used to treat. Although successful in several studies, there is a lack of solid evidence as to why Sanyangxuedai has an effect on leukemia, and little is known about the underlying mechanisms. In this study, the active ingredients of cinnamon were isolated, purified, and identified. The transwell transport pool formed with the Caco-2 cell model was used to filter the active ingredients of cinnamon by simulating the gastrointestinal barrier in vitro. Moreover, the cell morphology, cell cycle status, apoptosis status, and antigenic variation of the cell surface antigens were observed and measured in K562 cells after treatment with the active ingredients of cinnamon. Our results showed that 50-75 MUM was a safe concentration of cinnamon extract for treatment of K562 cells for 72 h. The cinnamon extract caused growth inhibition of K562 cells. Cinnamon extract seemed to arrest the cells at the G1 stage and increased the apoptosis rate significantly. Interestingly, cinnamon extract treatment upregulated the expression of erythroid and myeloid differentiation antigens and downregulated that of the megakaryocytic differentiation antigens in a dose-dependent manner. Our findings indicate that cinnamon extract from Sanyangxuedai may be effective for treating leukemia. PMID- 27706568 TI - Comparison of methods to preserve Rheum palmatum (Polygonaceae) for efficient DNA extraction and PCR amplification. AB - In this study, we compared the quality of DNA extracted using the modified CTAB method, from Rheum palmatum leaves preserved using fourteen different methods, including ones used commonly in other species: under ultra-cold (-80 degrees C) temperatures, after drying with an absorbent paper, desiccating using a silica gel, drying at 60 degrees C, in 70% ethanol, absolute ethanol, 70% ethanol supplemented with 50 mM EDTA, SDS-DNA extracting solution, nuclear separation buffer, improved NaCl-CTAB solution, TE-buffer, I-solution, or II-solution. DNA extracted from fresh leaves was used as the control. The quality of extracted DNA was evaluated based on the success of PCR amplification of the ITS2 region and a microsatellite marker. DNA was not extracted from samples preserved in the nuclear separation buffer and II-solution. The purities of DNA extracted from leaves preserved in ultra-cold temperatures, 70% ethanol, and 70% ethanol with 50 mM EDTA, and after desiccating using a silica gel and drying were higher, and comparable to the purity of DNA extracted from fresh leaves, than those of leaves preserved using other methods. In the present study, combined with the PCR amplifications, the preservation using ultra-cold temperatures, silica gel desiccation, or drying, and PCR amplification of the extracted DNA can be used for further molecular studies in R. palmatum. PMID- 27706569 TI - Development and characterization of microsatellite loci in Excentrodendron hsienmu (Chun & How) H.T. Chang& R.H. Miau. AB - Microsatellite markers were isolated using dual-suppression-PCR for the endangered species Excentrodendron hsienmu (Tiliaceae) to evaluate the genetic diversity and population structure of this species. A total of 11 polymorphic microsatellite loci were characterized in E. hsienmu. The number of alleles per locus ranged from 2 to 9, with an average of 5.27. The expected heterozygosity value ranged from 0.053 to 0.780, with an average of 0.568 and the observed heterozygosity value ranged from 0 to 0.595, with an average of 0.268. The polymorphic information content value ranged from 0.051 to 0.740, with an average of 0.521. These newly designed markers will be of great potential significance and profound influence in future research related to the genetic diversity, population structure, and patterns of gene flow of this species, which will contribute to the implementation of conservation and management strategies for this species. PMID- 27706570 TI - Role of IL-8 gene polymorphisms in glioma development in a Chinese population. AB - This case-control study aimed to investigate the role of -251 T>A (rs4073) and 781 C>T (rs2227306) polymorphisms in the interleukin-8 (IL-8) gene in the development of glioma in a Chinese population. One hundred and twenty-seven glioma patients and 284 healthy control subjects were recruited to this study between February 2013 and December 2014. The IL-8 -251 T>A (rs4073) and -781 C>T (rs2227306) polymorphisms were genotyped by polymerase chain reaction coupled with restriction fragment length polymorphism. The patients and control subjects were comparable by gender (X2 = 1.24, P = 0.27), tobacco smoking status (X2 = 0.80, P = 0.37), alcohol consumption status (X2 = 0.97, P = 0.32), and family history of cancer (X2 = 1.54, P = 0.22). The age of glioma patients was statistically lower than that of control subjects (t = 2.87, P = 0.002). The chi square test revealed the lack of any statistically significant differences in the genotype distributions of IL-8 rs4073 (X2 = 0.89, P = 0.64) and rs2227306 (X2 = 2.58, P = 0.28) between the glioma patients and control subjects. Unconditional logistic regression analysis revealed that the IL-8 rs4073 and rs2227306 gene polymorphisms did not contribute to the development of glioma. In conclusion, we determined that there is a lack of evidence suggesting a significant association between the IL-8 rs4073 and rs2227306 gene polymorphisms and the development of glioma in a Chinese population. PMID- 27706571 TI - Effects of Shenkangling intervention on the MAPK pathway in rats with doxorubicin induced nephropathy. AB - Shenkangling plays a role of Yishenhuoxue effect for the treatment of children with nephrotic syndrome. The aim of this study was to investigate the effects of Shenkangling intervention on the mitogen-activated protein kinase (MAPK) pathway in rats with Adriamycin-induced nephropathy (AN) and its underlying mechanism of action. Nephrosis was induced in healthy Sprague-Dawley rats by doxorubicin and the rats were untreated or treated with prednisone, simvastatin, Shenkangling, or a combination thereof. Using real-time PCR, the mRNA expression levels of Chemokine (C-X-C motif) ligand 16 (CXCL16), A Disintegrin and metalloproteinase domain-containing protein 10 (ADAM10), and ADAM17 in the renal tissues of these rats were found to be decreased by the various treatments compared to those in the untreated doxorubicin-induced nephrosis rats. To quantify the activation of the MAPK pathway, western blotting was used to detect the phosphorylation levels of MAPK pathway-associated proteins (p38, ERK1/2, SAPK/JNK) and nuclear factor (NF)-kappaB p65, which were reduced by the various treatments compared to those in the untreated doxorubicin-induced rats. Serum levels of transforming growth factor (TGF)-beta1, tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, and IL-6, quantified by ELISA, were decreased by the various treatments compared to the levels in the untreated doxorubicin-induced nephrosis rats. The rats treated with prednisone, simvastatin, and Shenkangling showed the best outcome. The Chinese medicine Shenkangling that is known for nourishing the kidney and promoting blood circulation reduced urinary protein levels, increased serum albumin levels, and reduced cholesterol levels by reducing the release of CXCL16, ADAM10, ADAM17, TGF-beta1, TNF-alpha, IL-1beta, IL- 6, and other inflammatory mediators and inhibiting the activation of the MAPK signaling pathway, thereby effectively improving the state of nephropathy in AN rats. These results indicate that Shenkangling can be used clinically to treat nephropathy. PMID- 27706572 TI - Detection of QTLs controlling fast kernel dehydration in maize (Zea mays L.). AB - In order to understand the effect of grain moisture of inbred lines at the silking and physiological maturity stages on kernel dehydration rate, 59 maize inbred lines from six subgroups were selected. Grain moisture was measured and QTLs associated with kernel dehydration were mapped. A rapid dehydration evaluation and association analysis revealed eight inbred lines with faster dehydration rate, including Yuanwu 02, K36, Zhonger/O2, Lo1125, Han 49, Qi 319, Hua 160, and PH4CV. A single sequence repeat analysis using 85 pairs detected five QTLs with phenotypic variation contribution >=10% in the permanent F2 generation populations Zheng 58 x S1776 and Chang 7-2 x K1131, which had LOD threshold values >= 3 in both 2013 and 2014. The chromosome region of qFkdr7b had not previously been reported and is preliminarily identified as a new major QTL. A false positive field verification of grain dehydration rate of 53 inbred lines indicated that the screening result of the rapid dehydration inbred lines by specific amplification with marker Phi114 was most similar to the field assessment result, followed by markers Phi127 and Phi029. The rapid dehydration lines selected based on primer Phi114 amplification were also similar to the field dehydration rate and can thus be used for molecular marker-assisted selection. A significant effort is needed to improve stress resistance and shorten the growth period via fast kernel dehydration in intermediate materials of the inbred lines K36, Zhonger/ O2, Lo1125, Han 49, Hua 160, and PH4CV, and further using the selected lines for new combinations. PMID- 27706573 TI - Isolation and characterization of polymorphic microsatellite markers in the endangered species Bretschneidera sinensis Hemsl. AB - Bretschneidera sinensis is an endangered species that is mainly distributed in South China. As a tertiary relict and the single species in the Bretschneideraceae family, it has a high conservation value. To investigate the influence of human disturbance on its mating system, 63 new microsatellites were developed using restriction-site-associated DNA sequencing and their polymorphisms were tested on 30 samples from one population. Among the 63 microsatellites, the number of alleles per locus ranged from 2 to 16. The observed and expected heterozygosities ranged from 0.133 to 0.967 and from 0.127 to 0.912, respectively. These microsatellites may be used for studying the mating system of B. sinensis as well as the within-population hereditary structure. PMID- 27706574 TI - Polymorphisms in ADAMTS4 and ADAMTS5 are not linked to susceptibility to knee osteoarthritis in the Turkish population. AB - Considering the functions of aggrecanase-1 (ADAMTS4) and -2 (ADAMTS5), which are thought to be the two major enzymes responsible for the destruction of aggrecans in arthritic diseases, we investigated whether important polymorphisms in the ADAMTS4 and ADAMTS5 genes affect osteoarthritis (OA) susceptibility. Our study took place in Mugla, Turkey. Ninety-five cases were recruited following OA diagnosis (72 women and 23 men), and 80 individuals without any symptoms or radiographic signs of OA (56 women and 24 men) were chosen as healthy controls. After obtaining DNA from patients and control subjects, ADAMTS4 and ADAMTS5 genotypes were determined using the ABI Prism StepOnePlus Real-Time system. In addition, we categorized patients based on OA grade. There were no significant differences in the genotype distributions of the four polymorphisms between the groups (P > 0.05). Moreover, ADAMTS4 and ADAMTS5 allele frequencies did not differ between OA and control participants (P > 0.05). These findings suggest that the ADAMTS4 (rs4233367 and rs11807350) and ADAMTS5 (rs226794 and rs2830585) variants examined may not contribute to susceptibility to knee OA in the Turkish population. Other gene polymorphisms should be assessed in order to explain variations in OA susceptibility. PMID- 27706576 TI - DNA barcoding and phylogenetic relationships of Ardeidae (Aves: Ciconiiformes). AB - The avian family Ardeidae comprises long-legged freshwater and coastal birds. There has been considerable disagreement concerning the intrafamilial relationships of Ardeidae. Mitochondrial cytochrome c oxidase subunit I (COI) was used as a marker for the identification and phylogenetic analysis of avian species. In the present study, we analyzed the COI barcodes of 32 species from 17 genera belonging to the family Ardeidae. Each bird species possessed a barcode distinct from that of other bird species except for Egretta thula and E. garzetta, which shared one barcoding sequence. Kimura two-parameter distances were calculated between barcodes. The average genetic distance between species was 34-fold higher than the average genetic distance within species. Neighbor joining and maximum likelihood methods were used to construct phylogenetic trees. Most species could be discriminated by their distinct clades in the phylogenetic tree. Both methods of phylogenetic reconstruction suggested that Zebrilus, Tigrisoma, and Cochlearius were an offshoot of the primitive herons. COI gene analysis suggested that the other herons could be divided into two clades: Botaurinae and Ardeinae. Our results support the Great Egret and Intermediate Egret being in separate genera, Casmerodius and Mesophoyx, respectively. PMID- 27706575 TI - Expression and validation of PvPGIP genes for resistance to white mold (Sclerotinia sclerotiorum) in common beans (Phaseolus vulgaris L.). AB - The interaction between polygalacturonase-inhibiting proteins (PGIPs), produced by plants, and endopolygalacturonases (PGs), produced by fungi, limits the destructive potential of PGs and can trigger plant defense responses. This study aimed to i) investigate variation in the expression of different common bean (Phaseolus vulgaris L.) genotypes and its relationship with resistance to white mold (Sclerotinia sclerotiorum); ii) determine the expression levels of PvPGIP genes at different time points after inoculation with white mold; and iii) investigate differences in PvPGIP gene expression between two white mold isolates with different levels of aggressiveness. Four bean lines were analyzed, including two lines from a recurrent selection for white mold (50/5 and 84/6), one resistant line that was not adapted to Brazilian conditions (Cornell 605), and one susceptible line (Corujinha). Gene expression was investigated at 0, 1, 2, 3, and 5 days after inoculation. The isolate UFLA 03 caused no significant difference in the relative expression of any gene examined, and was inefficient in discriminating among the genotypes. For the isolate UFLA 116, all of the genes were differentially expressed, as they were associated with resistance to white mold, and the expressions increased until the third day after inoculation. The 50/5 line was not significantly different from the Corujinha line for all of the genes analyzed. However, this line had a resistance level that was similar to that of Cornell 605, according to the straw test. Therefore, the incorporation of PvPGIP genes can increase the resistance of lines derived from recurrent selection.

AB - Bioactive oils extracted from sea buckthorn (Hippophae rhamnoides) berries contain highly nutritional and medicinal compounds; however, the oil contents of sea buckthorn berries are very low. Thirteen inter-simple sequence repeat (ISSR) primers were used to identify markers associated with oil content of dry pulp in 51 cultivars and lines, which clustered into three major groups based on 137 polymorphic markers. Dry pulp oil contents in 45 cultivars and lines in Group I ranged from 6.6 to 33.1%; these accessions belonged to H. rhamnoides ssp mongolica and its hybrids with H. rhamnoides ssp sinensis. Three lines (H. rhamnoides ssp mongolica) in Group II had high dry pulp oil contents (33.7 to 37.5%), whereas three lines of hybrids in Group III had low dry pulp oil contents (10.9 to 17.5%). The dry pulp oil content of H. rhamnoides ssp mongolica (27.2 +/ 0.9%) was higher than that of hybrids (12.0 +/- 1.2%) (P < 0.01). Four ISSR markers (881340, 8251000, 817380, and 8071100) had positive association with high dry pulp oil content (P < 0.01) using stepwise multiple regression analysis. The use of these ISSR markers is a potential strategy to select genotypes with high dry pulp oil content and suitable parental combinations for improvement of sea buckthorn berries. PMID- 27706579 TI - Spermatogenesis in Nesotriatoma bruneri (Usinger 1944) (Hemiptera, Triatominae). AB - The Nesotriatoma genus consists of the species N. flavida N. bruneri and N. obscura, forming the Flavida complex. Variation in the size and morphological differences intraspecific of N. flavida led to the description of N. bruneri. Two years later, the same author proposed the synonymization of N. bruneri with N. flavida. Only in 1981 the specific status N. bruneri was recovered by means of morphological analysis of the genitalia. However, recently by genetic analysis, it was suggested that N. bruneri and N. flavida should be again synonymized. As Chagas disease has no cure, the main way to minimize the incidence of this disease is by vector control. Thus, grouping biological data from these hematophagous insects can assist in the development of vector control programs and mainly assist in taxonomic issues of synonymization. Thus, this paper describes spermatogenesis of N. bruneri. Three adult N. bruneri males were cytogenetically analyzed. The meiotic behavior observed for N. bruneri was very similar to that observed for the triatomine species with 23 chromosomes: during prophase, chromatin compaction was observed, the chromocenter composition was characterized (X1, X2 and Y), and the species karyotype was confirmed as 2n = 23 (20A + X1X2Y), as it was observed for N. flavida. Moreover, it was possible to observe anaphase and telophase. Thus, this study describes reproductive aspects of N. bruneri in order to contribute to the biological knowledge of these insects of epidemiological importance. Furthermore, this corroborates the synonymization of N. bruneri with N. flavida.

AB - Determining correlations between certain traits of economic importance constitutes an essential component of selective activities. In this study, our aim was to provide effective indicators for breeding programs of Lateolabrax maculatus, an important aquaculture species in China. We analyzed correlations between 20 morphometric traits and body weight, using correlation and path analyses. The results indicated that the correlations among all 21 traits were highly significant, with the highest correlation coefficient identified between total length and body weight. The path analysis indicated that total length (X1), body width (X5), distance from first dorsal fin origin to anal fin origin (X10), snout length (X16), eye diameter (X17), eye cross (X18), and slanting distance from snout tip to first dorsal fin origin (X19) significantly affected body weight (Y) directly. The following multiple-regression equation was obtained using stepwise multiple-regression analysis: Y = -472.108 + 1.065X1 + 7.728X5 + 1.973X10 - 7.024X16 - 4.400X17 - 3.338X18 + 2.138X19, with an adjusted multiple correlation coefficient of 0.947. Body width had the largest determinant coefficient, as well as the highest positive direct correlation with body weight. At the same time, high indirect effects with six other morphometric traits on L. maculatus body weight, through body width, were identified. Hence, body width could be a key factor that efficiently indicates significant effects on body weight in L. maculatus.

AB - In this study, we determined the complete nucleotide sequence of the mitochondrial (mt) DNA of the paddy frog Fejervarya multistriata. mtDNA is 17,750 bp long and contains 13 protein-coding regions, 2 ribosomal RNA, non-coding genes, and 23 tRNA because of the presence of an extra copy of tRNA-Met. The gene arrangements among two related species of Fejervarya were compared, and the combined mtDNA data were subjected to a phylogenetic analysis. Interestingly, we observed a unique translocation of the tRNA-Leu gene, similar to that reported in previous studies on two Fejervarya species. Phylogenetic analyses supported the classification into two evolutionary clades, Ranidae and Dicroglossidae, as well as placement of Hylarana guentheri in the genus Babina. Our results suggested that Fejervarya limnocharis and Fejervarya multistriata may be conspecific, because of its low pairwise genetic distance. However, these results must be further validated with additional analyses. PMID- 27706581 TI - The common CARD14 gene missense polymorphism rs11652075 (c.C2458T/p.Arg820Trp) is associated with psoriasis: a meta-analysis. AB - Recent genetic evidence suggests a robust association of the CARD14 single nucleotide polymorphism rs11652075 (c.C2458T/p.Arg820Trp) and other rare mutations in this gene with psoriasis. To assess whether combined data support the relationship between CARD14 rs11652075 and susceptibility to this disease, we conducted a meta-analysis. PubMed (MEDLINE), EMBASE, Web of Science, and the Cochrane Library were searched for relevant papers published in English. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random effect models. Heterogeneity between studies was assessed using the Cochran's Q and I2 statistics. A total of five published studies, including 32,807 psoriasis patients and 45,458 controls, met our inclusion criteria and were included in the meta-analysis. The pooled OR of the association between the minor allele of this polymorphism and psoriasis was 0.877 (95%CI = 0.834-0.922; P < 0.001). In a stratified analysis, pooled ORs relating to European and Asian ancestry were 0.883 (95%CI = 0.822-0.948) and 0.872 (95%CI = 0.812-0.936), respectively. Those calculated for studies with case sample sizes above and below 1000 were 0.912 (95%CI = 0.870- 0.956) and 0.824 (95%CI = 0.734-0.924), respectively. No publication bias was present, and the exclusion of any single dataset did not substantially alter the corresponding pooled ORs. Due to the limited data available regarding clinical classification of cases and genotypes, subgroup stratification by clinical type was not performed. Our results demonstrate a significant association between the CARD14 rs11652075 polymorphism and psoriasis. PMID- 27706582 TI - Association between the -174 G/C polymorphism of the interleukin-6 gene and myocardial infarction risk: a meta-analysis. AB - Numerous studies have evaluated the association between the -174 G/C polymorphism in the interleukin-6 gene (IL6) and myocardial infarction (MI) risk. However, the results from the published studies are inconclusive. The aim of this meta analysis was to determine whether the IL6 -174 G/C polymorphism is associated with MI risk. A meta-analysis based on nine case-control studies was performed to address this issue. No significant associations between IL6 -174 G/C polymorphism and MI risk were observed in any of the genetic models (CC vs GG: OR = 1.18, 95%CI = 0.92-1.52; CG vs GG: OR = 1.09, 95%CI = 0.93-1.27; dominant model: OR = 1.11, 95%CI = 0.94-1.31; recessive model: OR = 1.10, 95%CI = 0.91-1.33). Furthermore, the subgroup analysis by ethnicity did not reveal a significant association between the IL6 -174 G/C polymorphism and susceptibility to MI in Caucasians. In conclusion, the results indicate that the IL6 -174 G/C polymorphism does not contribute to MI risk. PMID- 27706583 TI - Association between expression of DNA mismatch repair genes and clinical features and prognosis of patients with radical resection of colon cancer. AB - The aim of this study was to investigate the clinical significance of the expression of DNA mismatch repair (MMR) genes in patients subjected to radical surgical removal of colon cancer, as well as their correlation with disease prognosis. Ninety stage II and III colon cancer patients who received laparoscopic radical resection of colon cancer at our hospital were recruited in this study. The expression of hMLH1, hMSH2, hMSH6, and hPMS2 in the resected tumor tissues was examined by SP immunohistochemistry, in order to analyze the relationship between defective DNA MMR (dMMR) and the clinico-pathological features and prognosis of colon cancer. Patients were followed up over a period of 5-35 months, and the Kaplan-Meier survival curve was plotted. dMMR was confirmed in 27 subjects (30.0%), among whom recurrence with metastasis and death was reported in 5 (18.5%) and 2 (7.4%) patients, respectively. The remaining 63 subjects displayed proficient DNA MMR (pMMR); among these, 19 (30.2%) and 7 (11.1%) recurrences with metastasis and death were reported, respectively. dMMR showed no significant correlation with gender, age, or therapeutic modality (P > 0.05), but was significantly correlated with the degree of differentiation, tumor location, number of resected lymph nodes, presence of ileus, and TNM stage (P < 0.05). The prognosis of patients with dMMR was better than that of patients with pMMR. dMMR serves as a biomarker for the prognosis of stage II/III colon cancers. PMID- 27706584 TI - In silico comparative analysis of tylenchid nematode pectate lyases. AB - Phytoparasitic nematodes can infect a wide range of crop plants, and cause billions of dollars of agricultural losses each year. These parasites represent the largest source of biotic stress experienced by plants. The order Tylenchida comprises the most important parasitic nematodes, particularly the root-knot and cyst nematodes. These parasitic organisms obtain nutrients to support their development through complex interactions with their hosts. Plant-parasitic nematodes secrete a mixture of cell-wall degrading enzymes to facilitate migration through the plant root. Enzymes are secreted that degrade the principal cell-wall components, cellulose, hemi-cellulose, or pectin. Pectate lyases are important parasitism factors in plant-parasitic nematodes. These enzymes degrade polygalacturonic acid, which is a fundamental constituent of pectin of host cell walls. Thus, pectate lyases permit the penetration and colonization of plant host cells by parasites. Here, we analyzed 22 pectate lyase protein sequences from tylenchid nematode species. Our results revealed great variation in the isoelectric points of pectate lyases, and groups of acidic and alkaline proteins that may have distinct enzymatic activities were identified. Phylogenetic analysis also revealed the presence of two main groups of pectate lyases with distinct chemical properties. Seven conserved motifs were identified, but only five were present in all sequences. Results of the molecular docking analysis revealed differences in the predicted interaction sites in the pectate lyases from the two groups. These results may provide a theoretical basis for future studies of host plant resistance to nematode infection. PMID- 27706585 TI - Effect of domestication on microorganism diversity and anaerobic digestion of food waste. AB - To accomplish the rapid start-up and stable operation of biogas digesters, an efficient inoculum is required. To obtain such an inoculum for food waste anaerobic digestion, we domesticated dairy manure anaerobic digestion residue by adding food waste every day. After 36 days, the pH and biogas yield stabilized signifying the completion of domestication. During domestication, the microbial communities in the inocula were investigated by constructing 16S rDNA clone libraries. We evaluated the effect of the domesticated inoculum by testing batch food waste anaerobic digestion with a non-domesticated inoculum as a control. The pH and methane yield of the digestion systems were determined as measurement indices. Domestication changed the composition and proportion of bacteria and archaea in the inocula. Of the bacteria, Clostridia (49.3%), Bacteroidales (19.5%), and Anaerolinaceae (8.1%) species were dominant in the seed sludge; Anaerolinaceae (49.0%), Clostridia (28.4%), and Bacteroidales (9.1%), in domestication sludge. Methanosaeta was the dominant genus in both of the seed (94.3%) and domestication (74.3%) sludge. However, the diversity of methanogenic archaea was higher in the domestication than in seed sludge. Methanoculleus, which was absent from the seed sludge, appeared in the domestication sludge (21.7%). When the domesticated inoculum was used, the digestion system worked stably (organic loading rate: 20 gVS/L; methane yield: 292.2 +/- 9.8 mL/gVS; VS = volatile solids), whereas the digestion system inoculated with seed sludge failed to generate biogas. The results indicate that inoculum domestication ensures efficient and stable anaerobic digestion by enriching the methanogenic strains. PMID- 27706586 TI - Mixed models identify physic nut genotypes adapted to environments with different phosphorus availability. AB - The aim of this study was to screen physic nut (Jatropha curcas) genotypes that differ in their phosphorous (P) use, using mixed models. The experiment was conducted in a greenhouse located in the experimental area of the Centro de Ciencias Agrarias of the Universidade Federal do Espirito Santo, in Alegre, ES, Brazil. The experiment was arranged in a randomized block design, using a 10 x 3 factorial scheme, including ten physic nut genotypes and two environments that differed in their levels of soil P availability (10 and 60 mg/dm3), each with four replications. After 100 days of cultivation, we evaluated the plant height, stem diameter, root volume, root dry matter, aerial part dry matter, total dry matter, as well as the efficiency of absorption, and use. The parameters were estimated for combined selection while considering the studied parameters: stability and adaptability for both environments were obtained using the harmonic mean of the relative performance of the predicted genotypic values. High genotype by environment interactions were observed for most physic nut traits, indicating considerable influences of P availability on the phenotypic value. The genotype Paraiso simultaneously presented high adaptability and stability for aerial part dry matter, total dry matter, and P translocation efficiency. The genotype CNPAE C2 showed a positive response to P fertilization by increasing both the total and aerial part dry matter. PMID- 27706587 TI - Usefulness of the HMRPGV method for simultaneous selection of upland cotton genotypes with greater fiber length and high yield stability. AB - The harmonic mean of the relative performance of genotypic predicted value (HMRPGV) method has been used to measure the genotypic stability and adaptability of various crops. However, its use in cotton is still restricted. This study aimed to use mixed models to select cotton genotypes that simultaneously result in longer fiber length, higher fiber yield, and phenotypic stability in both of these traits. Eight trials with 16 cotton genotypes were conducted in the 2008/2009 harvest in Mato Grosso State. The experimental design was randomized complete blocks with four replicates of each of the 16 genotypes. In each trial, we evaluated fiber yield and fiber length. The genetic parameters were estimated using the restricted maximum likelihood/best linear unbiased predictor method. Joint selection considering, simultaneously, fiber length, fiber yield, stability, and adaptability is possible with the HMRPGV method. Our results suggested that genotypes CNPA MT 04 2080 and BRS CEDRO may be grown in environments similar to those tested here and may be predicted to result in greater fiber length, fiber yield, adaptability, and phenotypic stability. These genotypes may constitute a promising population base in breeding programs aimed at increasing these trait values. PMID- 27706588 TI - Assessment of genetic relationship among Rhododendron cultivars using amplified fragment length polymorphism and inter-simple sequence repeat markers. AB - Genetic relationships of 17 Rhododendron cultivars, China, were assessed using inter-simple sequence repeat (ISSR) and amplified fragment length polymorphism (AFLP) markers. A total of 133 bands were obtained using nine selected ISSR primers, 129 (96.99%) of which were polymorphic; 267 bands were amplified by four AFLP primer pairs, 251 (94.01%) of which exhibited polymorphism. Based on these polymorphic products, a cluster analysis revealed similarities between the results of the ISSR and AFLP. All of the cultivars were clustered into two major branches; one branch contained the same four cultivars, and the other cultivars were separated into different groups in the other branch. The cluster results showed that the genetic relationships of the 17 cultivars were partly related to their morphological characteristics, particularly the flowering phase. Therefore, the results of this study support the classification of Rhododendron cultivars according to flowering phase. In addition, the cluster results can be used to select suitable parents for breeding. PMID- 27706589 TI - Heterogeneous evolution of Ty3-gypsy retroelements among bamboo species. AB - Ty3-gypsy long-terminal repeat retroelements are ubiquitously found in many plant genomes. This study reports the occurrence of heterogeneous Ty3-gypsy retroelements in four representative bamboo species: Phyllostachys heterocycla (Carr.) Mitford cv. pubescens, P. heterocycla (Carr.) Mitford cv. heterocycla, Dendrocalamopsis oldhami, and Pleioblastus fortunei. Using degenerate oligonucleotide primers corresponding to the conserved domains of reverse transcriptase (rt) genes of Ty3-gypsy retroelements, 165 distinct sequences were amplified from genomic DNA. The length of the nucleotide sequences varied from 366 to 438 bp. The sequences demonstrated a high heterogeneity, with homology ranging from 52.2 to 99.8%. A phylogenetic tree was constructed, including Arabidopsis thaliana and Oryza sativa. Bamboo Ty3-gypsy sequences formed three distinct retroelement clusters (gypsy I-III). Further analysis indicated that there were not only nearly identical Ty3-gypsy retroelements found in distantly related species, but also highly diverse Ty3-gypsy retroelements observed in closely related species. The results of this study provide genetic and evolutionary information about the bamboo genome that could contribute to further studies of repetitive elements in bamboo as well as in other species. PMID- 27706590 TI - Development of two novel specific SCAR markers by cloning improved RAPD fragments from the medicinal mushroom Ganoderma lucidium (Leysser: Fr) Karst. AB - Development of sequence-characterized amplified region (SCAR) markers from random amplified polymorphic DNA (RAPD) fragments is a valuable molecular approach for the genetic identification of different species. By using SCAR markers, molecular analysis is reduced to a simple polymerase chain reaction (PCR) analysis using primers designed from the amplicon sequence of RAPD. In this study, the DNA fragments from an improved RAPD amplification of Ganoderma species were cloned into a pGM-T vector; positive clones were identified by PCR amplification and enzymatic digestion, and finally, DNA fragments were sequenced using the Sanger sequencing method for developing the SCAR markers. Two SCAR markers, named LZ4-1 with 534 nucleotides, and LZ5-2 with 337 nucleotides were identified, which are specific to Ganoderma lucidium (Leysser: Fr) Karst species. BLAST of these two nucleotide sequences in the GenBank database showed no identity to other species. We deposited these sequences into the GenBank database (LZ4-1 accession No. KM391933, LZ5-2 accession No. KM391934). PCR assays confirmed them as novel molecular markers for G. lucidium (Leysser: Fr) Karst, which might be used for genetic authentication of adulterant samples. Thus, our study developed two specific SCAR markers for identifying and distinguishing the medicinal mushroom G. lucidium (Leysser: Fr) Karst from other Ganoderma species. PMID- 27706591 TI - Polymorphisms of eNOS, catalase, and myeloperoxidase genes in prostate cancer in Turkish men: preliminary results. AB - Prostate cancer (PCa) is the most common type of neoplasm in European males. Genetic and epigenetic factors contribute to PCa development and progression. In this study, we aimed to assess the relationship between PCa and polymorphisms in the genes encoding endothelial nitric oxide synthase (eNOS), catalase (CAT), and myeloperoxidase (MPO). In total, 193 patients were included in the study. Patients were divided into three groups: PCa (78), benign prostate hyperplasia (40), and control males (75). The parameters assessed included body mass index (BMI), smoking habits, presence of prostatism, prostate-specific antigen (PSA) levels, Gleason scores of prostate specimens, as well as polymorphisms in eNOS G894T, CAT- 262T, and MPO G-463T genes. BMI and smoking status of controls and patient groups showed no significant difference. CAT-262T gene polymorphism was found to be homozygous in 35.4% of PCa patients, which was 4.02-fold that in the controls (P = 0.006). There was no statistically significant difference in eNOS G894T and MPO G-463T gene polymorphisms between any of the groups. In conclusion, we found catalase levels to be associated with PCa diagnosis and PSA value. We did not find any significant differences between groups for other polymorphisms, but we believe that further studies with a large sample size may be needed before drawing definite conclusions. PMID- 27706592 TI - Balanced reciprocal translocation at amniocentesis: cytogenetic detection and implications for genetic counseling. AB - Balanced translocation is a common structural chromosomal rearrangement in humans. Carriers can be phenotypically normal but have an increased risk of pregnancy loss, fetal death, and the transmission of chromosomal abnormalities to their offspring. Existing prenatal screening technologies and diagnostic procedures fail to detect balanced translocation, so genetic counseling for carriers remains a challenge. Here, we report the characteristics of chromosomal reciprocal translocation in 3807 amniocentesis cases. Of the 16 detected cases of fetal reciprocal translocation, 8 cases (50%) showed positive biochemical marker screening; 3 cases (18.75%) were the parental carriers of a chromosomal abnormality; 2 (12.5%) were of advanced maternal age, 2 (12.5%) had a previous history of children with genetic disorders, and 1 case (6.25%) was associated with positive soft markers in obstetric ultrasound. Chromosomes 5 and 19 were the most commonly involved chromosomes in balanced translocations. Of the 13 cases with fetal balanced translocations, 8 (61.5%) were inherited from a paternal chromosome, 3 (23.1%) from a maternal chromosome, and 2 (15.4%) cases were de novo. The incidence of balanced translocation at amniocentesis was 0.42%. Male carriers of reciprocal chromosome translocation appear to have a higher chance of becoming a parent of a child born by normal childbirth than female carriers. PMID- 27706593 TI - Number of repetitions for evaluating technological traits in cotton genotypes. AB - With the changes in spinning technology, technological cotton traits, such as fiber length, fiber uniformity, fiber strength, fineness, fiber maturity, percentage of fibers, and short fiber index, are of great importance for selecting cotton genotypes. However, for accurate discrimination of genotypes, it is important that these traits are evaluated with the best possible accuracy. The aim of this study was to determine the number of measurements (repetitions) needed to accurately assess technological traits of cotton genotypes. Seven experiments were conducted in four Brazilian States (Ceara, Rio Grande do Norte, Goias, and Mato Grosso do Sul). We used nine brown and two white colored fiber lines in a randomized block design with four replications. After verifying the assumptions of residual normality and homogeneity of variances, analysis of variance was performed to estimate the repeatability coefficient and calculating the number of repetitions. Trials with four replications were found to be sufficient to identify superior cotton genotypes for all measured traits except short fiber index with a selective accuracy >90% and at least 81% accuracy in predicting their actual value. These results allow more accurate and reliable results in future researches with evaluating technological traits in cotton genotypes. PMID- 27706594 TI - Genetic and epigenetic diversity and structure of Phragmites australis from local habitats of the Songnen Prairie using amplified fragment length polymorphism markers. AB - The genetic and epigenetic diversity and structure of naturally occurring Phragmites australis populations occupying two different habitats on a small spatial scale in the Songnen Prairie in northeastern China were investigated by assessing amplified fragment length polymorphisms (AFLPs) and methylation sensitive amplified polymorphisms (MSAPs) through fluorescent capillary detection. The two groups of P. australis were located in a seasonal waterlogged low-lying and alkalized meadow with a pH of 8-8.5 and in an alkaline patch without accumulated rainwater and with a pH greater than 10. These groups showed high levels of genetic diversity at the habitat level based on the percentage of polymorphic bands (90.32, 82.56%), Nei's gene diversity index (0.262, 0.248), and the Shannon diversity index (0.407, 0.383). Although little is known about the between-habitat genetic differentiation of P. australis on a small spatial scale, our results implied significant genetic differentiation between habitats. Extensive epigenetic diversity within habitats, along with clear differentiation, was found. Specifically, the former habitat (Habitat 1, designated H1) harbored higher levels of genetic and epigenetic diversity than the latter (Habitat 2, designated H2), and population-level diversity was also high. This study represents one of few attempts to predict habitat-based genetic differentiation of reeds on a small scale. These assessments of genetic and epigenetic variation are integral aspects of molecular ecological studies on P. australis. Possible causes for within- and between-habitat genetic and epigenetic variations are discussed. PMID- 27706595 TI - Genetic diversity in natural populations of mangaba in Sergipe, the largest producer State in Brazil. AB - Mangaba (Hancornia speciosa Gomes) is found in areas of coastal tablelands in the Brazilian Northeast and Cerrado regions. This species has been subjected to habitat fragmentation that is mainly due to human activity, and requires conservation strategies. The aim of this study was to analyze the structure and inter- and intrapopulation genetic diversity of natural populations of H. speciosa Gomes using inter-simple sequence repeat (ISSR) molecular markers. A total of 155 individuals were sampled in 10 natural populations (ITA, PAC, IND, EST, BC, PIR, JAP, BG, NEO, and SANT) in the State of Sergipe, Brazil. Fifteen primers were used to generate 162 fragments with 100% polymorphism. Genetic analysis showed that the variability between populations (77%) was higher than within populations (23%). It was possible to identify five different groups by the unweighted pair group method with arithmetic mean and principal coordinate analysis, and only one individual (E10) remained isolated. Using ISSR markers it was possible to obtain a molecular profile of the populations evaluated, showing that these markers were effective and exhibited sufficient polymorphism to estimate the genetic variability of natural populations of H. speciosa Gomes. PMID- 27706596 TI - Detecting the potential cancer association or metastasis by multi-omics data analysis. AB - Comprehensive multi-omics data analyses have become an important means for understanding cancer incidence and progression largely driven by the availability of high-throughput sequencing technologies for genomes, proteomes, and transcriptomes. However, how tumor cells from the site of origin of the cancer begin to grow in other sites of the body is very poorly understood. In order to examine potential connections between different cancers and to gain an insight into the metastatic process, we conducted a multi-omics data analysis using data deposited in The Cancer Genome Atlas database. By combining somatic mutation data along with DNA methylation level and gene expression level data, we applied a Bayesian network analysis to detect the potential association among four distinct cancer types namely, Head and neck squamous cell carcinoma (Hnsc), Lung adenocarcinoma (Luad), Lung squamous cell carcinoma (Lusc), and Skin cutaneous melanoma (Skcm). Further validation based on the 'identification of somatic signatures' and the 'association rules analysis' confirmed these associations. Previous investigations have suggested that common risk factors and molecular abnormalities in cell-cycle regulation and signal transduction predominate among these cancers. This evidence indicates that our study provides a rational analysis and hopefully will help shed light on the links between different cancers and metastasis as a whole. PMID- 27706597 TI - Epigenetic mechanism of maternal post-traumatic stress disorder in delayed rat offspring development: dysregulation of methylation and gene expression. AB - Maternal post-traumatic stress disorder (PTSD) increases the risk of adverse neurodevelopmental outcomes in the child. Epigenetic alternations may play an essential role in the negative effects of PTSD. This study was aimed to investigate the possible epigenetic alterations of maternal PTSD, which underpins the developmental and behavioral impact. 24 pregnant Sprague-Dawley (SD) rats were randomly grouped into PTSD and control groups. Open-field tests (OFTs), elevated pull maze (EPM) assays, gene expression profile chip tests, and methylated DNA immunoprecipitation sequencing (MeDIP-Seq) were performed on the offsprings 30 days after birth. The results showed that PTSD offsprings had lower body weights and OFT scores than control offsprings. Enzyme-linked immunosorbent assays showed that serotonin receptor (5-HT) and dopamine levels were significantly lower in PTSD offsprings than in control offsprings. In contrast, corticosterone levels were higher in the PTSD group than in the control group. In a comparison of the PTSD group versus the control group, 4,160 significantly differentially methylated loci containing 30,657 CpGs were identified; 2,487 genes, including 13 dysmethylated genes, were validated by gene expression profiling, showing a negative correlation between methylation and gene expression (R = -0.617, P = 0.043). In conclusion, maternal PTSD could delay the physical and behavioral development of offsprings, and the underlying mechanism could contribute to changes in neurotransmitters and gene expression, owing to dysregulation of whole-genome methylation. These findings could support further clinical research on appropriate interventions for maternal PTSD to prevent methylation dysregulation and developmental retardation. PMID- 27706598 TI - Defective eyelid leading edge cell migration in C57BL/6-corneal opacity mice with an "eye open at birth" phenotype. AB - Development of the eyelid requires coordination of the cellular processes involved in proliferation, cell size alteration, migration, and cell death. C57BL/6J-corneal opacity (B6-Co) mice are mutant mice generated by the administration of N-ethyl-N-nitrosourea (100 mg/kg). They exhibit the eyelids open at birth phenotype, abnormal round cell shape from tightened F-actin bundles in leading edge keratinocytes at E16.5, and gradual corneal opacity with neovessels. The tip of the leading edge in B6-Co mice did not move forward, and demonstrated a sharp peak shape without obvious directionality. Analysis of the biological characteristics of B6-Co mice demonstrated that abnormal migration of keratinocytes could affect eyelid development, but proliferation and apoptosis in B6-Co mice had no effect. Mutant gene mapping and sequence analysis demonstrated that in B6-Co mice, adenosine was inserted into the untranslated regions, between 3030 and 3031, in the mRNA 3'-terminal of Fgf10. In addition, guanine 7112 was substituted by adenine in the Mtap1B mRNA, and an A2333T mutation was identified in Mtap1B. Quantitative real-time polymerase chain reaction analysis showed that expression of the Hbegf gene was significantly down-regulated in the eyelids of B6- Co mice at E16.5, compared to B6 mice. However, the expression of Rock1, Map3k1, and Jnk1 genes did not show any significant changes. Abnormal keratinocyte migration and down-regulated expression of the Hbegf gene might be associated with impaired eyelid development in B6-Co mice. PMID- 27706599 TI - MicroRNA-338-3p inhibits glucocorticoid-induced osteoclast formation through RANKL targeting. AB - The differentiation deficiencies of osteoclast precursors (pre-OCs) may contribute to osteoporosis. Research on osteoporosis has recently focused on microRNAs (miRNAs) that play crucial roles in pre-OC differentiation. In the current study, we aimed to analyze the expression and function of the glucocorticoid (GC)-associated miRNA-338-3p (miR-338-3p) in osteoclast formation. We found that dexamethasone induced osteoclast differentiation and inhibited miR 338-3p expression. Overexpression of an miR-338-3p mimic in osteoclast precursor cells attenuated GC-induced osteoclast formation and bone resorption, whereas inhibition of miR-338-3p reversed these effects. The expression of the nuclear factor kappaB ligand RANKL, a potential target gene of miR-338-3p, was inversely correlated with miR-338-3p expression in pre-OCs. Furthermore, we demonstrated that RANKL was directly regulated by miR-338-3p and re-introduction of RANKL reversed the inhibitory effects of miR-338-3p on osteoclast formation and bone resorption. Taken together, these findings demonstrate that miR-338-3p may play a significant role in GC-induced osteoclast differentiation and function by targeting RANKL in osteoclasts. PMID- 27706601 TI - Pheno-morphological variation, genetic diversity and population structure of Tunisian Echinus Medic (Medicago ciliaris L.). AB - Medicago ciliaris L., considered as a valuable genetic resource, is a good candidate for the improvement of marginal or degraded lands with low fertility or high salinity. In this study, the pheno-morphological and genetic diversity were investigated in 14 Tunisian populations of M. ciliaris for the first time. Fourteen morphological traits showed significant differentiation between populations and high levels of diversity. Two amplified fragment length polymorphism primer combinations (E-AGC/M-CAA; E-AAG/M-CTG) were analyzed using an automated capillary electrophoresis system. A total of 528 loci were generated, of which 54% were polymorphic. Allelic polymorphism ranged from 0.02 to 0.5. Significant variation between populations was found for gene diversity, mean number of alleles per locus and Shannon index for which mean values were 0.17, 0.26, and 1.57, respectively. Analysis of molecular variance revealed a high rate of genetic variation within populations. Principal component analysis and genotypic clustering discriminated M. ciliaris populations according to their geographical origin. M. ciliaris clustered into three main groups. The first group was associated with high inland and cold areas, the second was defined by low areas with mild winters while the third described low coastal areas. Similarity of morphological and molecular results indicated that either markers could be used for the study of genetic diversity in this species. PMID- 27706600 TI - Analysis of the prevalence of polymorphisms in the glutathione S transferase gene (GST) in cataract patients from Goiania. AB - The aim of this study was to determine the prevalence of polymorphisms in the glutathione S-transferase genes GSTM1 and GSTT1 in patients with lens opacity (cataract). Peripheral blood samples were obtained from male and female patients (N = 23) with cataract. The GSTM1 and GSTT1 polymorphic regions were amplified by polymerase chain reaction, and the amplification products were electrophoresed on a 2% agarose gel. The obtained bands were by staining with ethidium bromide. The results were compared by a chi-square test using the BioEstat software (v.5.0). The frequencies of the GSTM1- and GSTT1-null genotypes were higher than those of the GSTM1- and GSTT1-present genotypes. The frequency of GSTT1-null genotypes was approximately 1.7 times higher than that of GSTM1, which was a statistically significant difference (P = 0.0019). Although a consensus remains to be reached on the correlation between genetic polymorphisms in GSTs and cataract susceptibility, the observations from most scientific studies are similar to those reported in this study. Thus, we conclude that the absence of these genes, particularly GSTT1, is correlated with the development of lens opacity.

AB - The anti-malarial drug, artemisinin, is quite expensive as a result of its slow content in Artemisia annua. Recent investigations have suggested that genetic engineering of A. annua is a promising approach to improve the yield of artemisinin. In this study, the transgenic A. annua strain GYR, which has high artemisinin content, was evaluated in an environmental release trial. First, GYR plants were compared with the wild-type variety NON-GYR, with regard to phenotypic characters (plant height, crown width, stem diameter, germination rate, leaf dry weight, 1000-seed weight, leave shape). Second, stress resistance in the two varieties (salt, drought, herbicide, and cold resistance) was evaluated under different experimental conditions. Finally, gene flow was estimated. The results indicated that there were significant differences in several agronomic traits (plant height, stem diameter, and leave dry weight) between the transgenic GYR and NON-GYR plants. Salt stress in transgenic and control plants was similar, except under high NaCl concentrations (1.6%, w/w). Leaf water, proline, and MDA content (increased significantly) were significantly different. Transgenic A. annua GYR plants did not grow better than NON-GYR plants with respect to drought and herbicide resistance. The two varieties maintained vitality through the winter. Third, gene flow was studied in an environmental risk trial for transgenic GYR. The maximum gene flow frequency was 2.5%, while the maximum gene flow distance was 24.4 m; gene flow was not detected at 29.2 m at any direction. Our findings may provide an opportunity for risk assessment in future commercialization of transgenic A. annua varieties. PMID- 27706603 TI - White mold resistance-associated quantitative trait loci in the Jalo x Small White common bean population. AB - We aimed to identify simple sequence repeat (SSR) markers linked to quantitative trait loci (QTLs) associated with white mold resistance in a segregating population derived from a cross between common bean cultivars Jalo and Small White, in the Southern State of Minas Gerais. Parents were crossed to obtain the F2 generation of 190 plants. From these, F2:3 and F2:4 progenies were obtained for phenotypic evaluation. DNA was extracted from F2 plants and parents for genotyping with SSR primers. For phenotypic assessment by the straw test, we used 190 F2:3 progenies and six lines in a triple-lattice design of 14 x 14 m. Nine trials were conducted for phenotyping by the oxalic acid method to evaluate 177 F2:4 progenies, in addition to the two parents and two common treatments represented by the Jalo and Corujinha lines. The experimental design for the oxalic acid method was completely randomized with three replicates. Adjusted means of evaluations related to F2:3 and F2:4 were used to identify QTLs by using the moving away method from the marker under Bayesian analysis. The markers GATS91, BM197, and X60000 stood out with high heritability and with effects on disease reduction by the straw test; therefore, these markers are promising for selection. The markers BM183, BM189, and SSR-IAC143 were associated with the QTLs identified by oxalic acid, providing greater effects in white mold resistance with high heritability. Based on the oxalic acid and straw test methods, the most prominent marker was PVBR189. PMID- 27706604 TI - Biplot analysis of strawberry genotypes recommended for the State of Espirito Santo. AB - Most strawberry genotypes grown commercially in Brazil originate from breeding programs in the United States, and are therefore not adapted to the various soil and climatic conditions found in Brazil. Thus, quantifying the magnitude of genotype x environment (GE) interactions serves as a primary means for increasing average Brazilian strawberry yields, and helps provide specific recommendations for farmers on which genotypes meet high yield and phenotypic stability thresholds. The aim of this study was to use AMMI (additive main effects and multiplicative interaction) and GGE biplot (genotype main effects + genotype x environment interaction) analyses to identify high-yield, stable strawberry genotypes grown at three locations in Espirito Santo for two agricultural years. We evaluated seven strawberry genotypes (Dover, Camino Real, Ventana, Camarosa, Seascape, Diamante, and Aromas) at three locations (Domingos Martins, Iuna, and Muniz Freire) in agricultural years 2006 and 2007, totaling six study environments. Joint analysis of variance was calculated using yield data (t/ha), and AMMI and GGE biplot analysis was conducted following the detection of a significant genotypes x agricultural years x locations (G x A x L) interaction. During the two agricultural years, evaluated locations were allocated to different regions on biplot graphics using both methods, indicating distinctions among them. Based on the results obtained from the two methods used in this study to investigate the G x A x L interaction, we recommend growing the Camarosa genotype for production at the three locations assessed due to the high frequency of favorable alleles, which were expressed in all localities evaluated regardless of the agricultural year. PMID- 27706605 TI - In silico characterization of 1,2-diacylglycerol cholinephosphotransferase and lysophospha-tidylcholine acyltransferase genes in Glycine max L. Merrill. AB - The enzymes 1,2-diacylglycerol cholinephosphotrans-ferase (CPT) and lysophosphatidylcholine acyltransferase (LPCAT) are important in lipid metabolism in soybean seeds. Thus, understand-ing the genes that encode these enzymes may enable their modification and aid the improvement of soybean oil quality. In soybean, the genes encoding these enzymes have not been completely described; there-fore, this study aimed to identify, characterize, and analyze the in silico expression of these genes in soybean. We identified two gene models encoding CPT and two gene models encoding LPCAT, one of which presented an alternative transcript. The sequences were positioned on the physical map of soybean and the promoter regions were analyzed. Cis-elements responsible for seed-specific expression and responses to biotic and abiotic stresses were identified. Virtual expression analysis of the gene models for CPT and LPCAT indicated that these genes are expressed under different stress conditions, in somatic embryos during differentiation, in immature seeds, root tissues, and calli. Putative ami-no acid sequences revealed the presence of transmembrane domains, and analysis of the cellular localization of these enzymes revealed they are located in the endoplasmic reticulum. PMID- 27706606 TI - Detecting multiple DNA human profile from a mosquito blood meal. AB - Criminal traces commonly found at crime scenes may present mixtures from two or more individuals. The scene of the crime is important for the collection of various types of traces in order to find the perpetrator of the crime. Thus, we propose that hematophagous mosquitoes found at crime scenes can be used to perform genetic testing of human blood and aid in suspect investigation. The aim of the study was to obtain a single Aedes aegypti mosquito profile from a human DNA mixture containing genetic materials of four individuals. We also determined the effect of blood acquisition time by setting time intervals of 24, 48, and 72 h after the blood meal. STR loci and amelogenin were analyzed, and the results showed that human DNA profiles could be obtained from hematophagous mosquitos at 24 h following the blood meal. It is possible that hematophagous mosquitoes can be used as biological remains at the scene of the crime, and can be used to detect human DNA profiles of up to four individuals. PMID- 27706607 TI - Effects of sodium lactate Ringer's injection on transfection of human protein kinase C-alpha antisense oligonucleotide in A549 lung cancer cells. AB - In the present study, we evaluated the effects of four solutions [Dulbecco's modified Eagle's medium (DMEM), sodium lactate Ringer's injection (SLRI), phosphate-buffered saline (PBS), and NaCl] on the transfection of the human protein kinase C-a antisense oligonucleotide (PKC-a ASO) aprinocarsen in human lung carcinoma A549 cells. Specifically, SLRI, DMEM, PBS, or NaCl were used as the growth solutions for A549 cells, and OPTI-MEM was used as the PKC-a ASO diluent for transfection. Additionally, SLRI, DMEM, PBS, or NaCl were used as both the growth solutions and diluents for transfection. The cell viability and transfection efficiency were determined. The results demonstrated that when SLRI was used as either the growth solution or both the growth solution and diluent for aprinocarsen transfection in A549 cells, the effects were close to the best effects observed with DMEM as the growth solution and OPTI-MEM as the diluent, which supported the transfection of aprinocarsen into the cells. Moreover, SLRI resulted in higher transfection efficiency than those of PBS and NaCl. In in vitro experiments, aprinocarsen effectively induced apoptosis in A549 cells. In conclusion, SLRI may replace PBS or NaCl in clinical trials as a transfection solution readily accepted by the human body. To our knowledge, this is the first report demonstrating the use of SLRI as a transfection solution in lung-cancer cell lines. PMID- 27706608 TI - Temporal and spatial expression of Smads and their correlation with YAP1 expression in sheep. AB - The temporal and spatial patterns of Smad and Yes-associated protein 1 (YAP1) expression were investigated in skeletal muscle (gastrocnemius muscle and extensor digitorum longus) at different growth stages (2 days old, 2 and 6 months old) in Hu sheep. Smads were differentially expressed in sheep skeletal muscle, with high expression in the gastrocnemius muscle and lower expression in the extensor digitorum longus. Expression of Smad2, Smad3, and Smad4 at the 2-day-old stage was significantly higher than at other stages (P < 0.05). The expression of Smad7 in 2-day-old sheep was lower than in 6-month-old sheep, with the lowest levels at 2 months. Smad expression was higher in males than in females at the 2 day-old stage, and expression in 2- and 6-month-old males was lower than that in 2-day-old females. Smad3 expression was higher in the 2-day- and 2-month-old males than in the females. There was a positive correlation (P < 0.01) between YAP1 and Smad2 expression in gastrocnemius muscle at the 2-month-old stage. YAP1 and Smad4/7 expression were positively correlated (P < 0.01) in extensor digitorum longus at the 2-day-old stage. YAP1 expression was negatively correlated with Smad7 in the extensor digitorum longus at 6 months. A significant difference between Smad2 and Smad3 (P < 0.01) expression in muscle was observed, consistent with Smad3 and Smad4 expression, indicating that these inhibit transforming growth factor-beta signaling in the same way. There was a positive correlation (P < 0.01) between YAP1 and MSTN expression, suggesting that YAP1 participates in muscle growth in sheep. PMID- 27706609 TI - Correlation of the TCF7L2 (rs7903146) polymorphism with an enhanced risk of type 2 diabetes mellitus: a meta-analysis. AB - Increasing evidence has demonstrated that a transcription factor 7-like 2 (TCF7L2) polymorphism (rs7903146) is significantly associated with type 2 diabetes mellitus (T2DM); however, limited sample size and variance of ethnicity in the studies investigating this association have led to conflicting reports regarding its role. Therefore, a comprehensive meta-analysis was conducted to quantitatively assess the association between the TCF7L2 polymorphism (rs7903146) and T2DM including published case-control studies in global populations. We searched the PubMed, EMbase, CNKI, and Wanfang databases for publications that studied correlation between TCF7L2 polymorphism (rs7903146) and risk of T2DM. Thirty-six studies from 30 eligible papers were identified. After data extraction and reference quality assessment, summary odds ratio and 95% confidence intervals (95%CI) of the TCF7L2 (rs7903146) polymorphism were calculated and combined using the fixed-effect model. Hardy-Weinberg equilibrium was evaluated to determine selection bias of the control subjects. Heterogeneity among studies was examined using the Q-test and the I2 test. Publication bias in studies was assessed using Begg's plots and the Egger test. The results showed that the rs7903146 T allele of the TCF7L2 gene was positively correlated with an enhanced risk of T2DM in the allelic, heterozygote, homozygote, dominant, and recessive models, with odds ratios of 1.35 (T vs C, 95%CI = 1.31-1.39), 1.32 (CT vs CC, 95%CI = 1.27-1.38), 1.74 (TT vs CC, 95%CI = 1.63-1.87), 1.40 (TT+CT vs CC, 95%CI = 1.35-1.46), and 1.59 (TT vs CT+CC, 95%CI = 1.49-1.69), respectively. No obvious publication bias was observed using the Egger linear test. PMID- 27706610 TI - Improved protocol for extracting genomic DNA from frozen formalin-fixed tissue resulting in high-quality whole mtDNA. AB - Formalin fixation and paraffin embedding is widely used for convenient and long term storage of tumor tissue and precious sources to perform genetic studies. However, DNA fragmentation is one of the major flaws of genomic DNA isolation from formalin fixation tissues, which limits its further usage. Here, we present an improved method for isolating high-quality genomic DNA from formalin fixation tissue. We obtained high-quality genomic DNA of more than 20 kb from samples frozen for more than 2 years. Furthermore, to verify DNA quality, the whole mitochondrial DNA (mtDNA) genomes from the normal and tumor tissue of the same patient were successfully amplified with two overlapping PCR fragments comprising more than 8379 bp in length for each fragment. In addition, the whole genomes were sequenced with a 48-well based primer panel in order to avoid potential sequencing errors from artificial recombination, which was further confirmed with an mtDNA phylogenetic strategy. Our improved DNA extraction method from formalin fixation tissue and sequencing strategy for entire mtDNA genomes will generate unambiguous sequence analysis results for clinical samples. PMID- 27706611 TI - Association of IL-1alpha gene polymorphism with susceptibility to type 1 diabetes in Chinese children. AB - The interleukin-1alpha (IL-1alpha) gene appears to play a role in the pathogenesis of type 1 diabetes (T1D). Therefore, the aim of this study was to investigate the contribution of the IL-1 rs1800587 gene polymorphism to susceptibility to T1D in Chinese children. This case-control study included 332 Chinese children with T1D and 332 healthy controls. Identification of genetic variants of rs1800587 in the IL-1alpha gene was performed by polymerase chain reaction amplification. The IL-1alpha rs1800587 polymorphism demonstrated a significant association with T1D risk. The allelic frequency significantly differed between the T1D and control groups [odds ratio (OR) = 0.7; 95% confidence interval (CI) = 0.52-0.86; P = 0.002]. Furthermore, significant differences were observed in the dominant model (CC/CT + TT; OR = 0.6; 95%CI = 0.46-0.85; P = 0.003). In T1D patients, the prevalence of hypertension in T allele carriers was 4.2-fold higher than that in C allele carriers, (95%CI = 2.67 6.58; P < 0.001). In conclusion, the present study found evidence of a significant association between the rs1800587 polymorphism in the IL-1alpha gene and T1D. PMID- 27706612 TI - Activation of Src tyrosine kinase in esophageal carcinoma cells in different regulatory environments and corresponding occurrence mechanism. AB - This study aims at observing the expression of activated Src tyrosine kinase in esophageal squamous cell carcinoma (ESCC), and exploring the relationship of Src tyrosine kinase with the occurrence and progression of ESCC. Immunohistochemistry, immunofluorescence, and immunoblotting are employed to investigate the expression of Src tyrosine kinase in the ESCC tissue. Cellular immunofluorescence is used to measure the expression of activated Src tyrosine kinase in TE1 and TE9 cell lines of human ESCC tissues and EPC1-htert and EPC2 htert cell lines of esophageal epithelial cells. Src tyrosine kinase is overexpressed in ESCC tissue and underexpressed in normal esophageal mucosa. Furthermore, it is overexpressed in the TE1 and TE9 cell lines of human ESCC tissue and underexpressed in the EPC1-htert and EPC2-htert cell lines of esophageal epithelial cells. Src tyrosine kinase shows a higher expression in human ESCC tissue than in normal esophageal mucosa. The difference is statistically significant (P < 0.05). The activation of Src tyrosine kinase plays an important role in the occurrence and development of ESCC. PMID- 27706613 TI - Dynamic QTL analysis of seed reserve utilization in sh2 sweet corn germination stages. AB - In this study, dynamic quantitative trait loci (QTL) were mapped in a recombinant inbred line (F2:4) population derived from a BF3109 x Q267 cross. This was done during the unconditional (4, 7, and 10 days) and conditional (0 to 4, 4 to 7, and 7 to 10 days) germination stages in sh2 sweet corn. The values of seedling dry weight, weight of mobilized seed reserve (WMSR), seed reserve depletion percentage (SRDP), seed reserve utilization efficiency (SRUE), and their heritability differed across the investigated stages. The heritabilities of these traits were lower at 7D/4D and 10D/7D compared with those at the 4- (4D/0D), 7- and 10-day (D) developmental stages. WMSR and SRDP were significantly negatively correlated with SRUE at the early stage. The unconditional QTL mapping can explain the accumulation of genetic effects of seed reserve utilization from the starting time, whereas the conditional QTL mapping can reveal genetic expression in the time intervals. Fifteen and fourteen additive QTLs were identified by the unconditional and conditional mapping, respectively. The number of additive QTLs and their effect values varied among the different stages. More additive QTLs were found at the later stage (7 to 10 days), based on the conditional mapping results. The identification of QTL mapping based on a combination of time dependent measurements is important for a better understanding of the genetic bases of seed reserve utilization. It is also important for the improvement of relevant variety traits for subsequent sweet corn-breeding studies using marker assisted selection. PMID- 27706614 TI - Characterization of gene methylation in human papillomavirus associated-head and neck squamous cell carcinoma. AB - Head and neck squamous cell carcinoma (HNSCC) has become one of the most common forms of cancer worldwide. Hypermethylation-induced silencing of tumor-associated gene has been proposed as an important cofactor in cancer pathology. This paper aimed to characterize the gene methylation patterns in human papillomavirus (HPV) associated-HNSCC. TIMP3 and APC methylation status in neoplastic (N = 92) and non neoplastic tissues (N = 92) of HNSCC as well as their association with HPV infection were investigated via methylation-specific PCR assays. Results indicated that methylation level of TIMP3 was markedly higher in HPV-positive tumors as compared with HPV-negative tumors. Both TIMP3 and APC methylation were associated with lymph node metastasis and higher clinical stage of tumors. Patients with methylation at TIMP3 or APC had worse prognoses as compared to those without these alterations. This is the first study that shows a possible linkage between HPV infection and APC methylation. Methylation patterns of tumor related genes may contribute to different disease prognosis in HNSCC according to the HPV infection status. PMID- 27706615 TI - HLA-G genetic variants and hepatocellular carcinoma: a meta-analysis. AB - Human leukocyte antigen (HLA)-G is a key tolerogenic molecule mainly expressed in the placenta and is crucial for implantation of the embryo and immunological tolerance of the fetus during pregnancy. However, under pathological conditions, such as cancer or viral infections, HLA-G can be expressed in other tissues. The gene coding for HLA-G (HLA-G, chromosome 6p21.3) presents numerous polymorphisms, some of them influencing its expression. One of the most studied, is the 14 bp ins/del (rs371194629) situated at the 3'-UTR of the gene. The insertion is thought to stabilize HLA-G mRNA. Different studies have analyzed the role of rs371194629 in hepatic injury, with either hepatotropic virus infection (i.e., HBV or HCV) or hepatocellular carcinoma (also induced by viral infection). Results from these studies are heterogeneous, differing with ethnicity and population age, and the role of rs371194629 is unclear. For these reasons, we decided to perform a meta-analysis of these results, concluding that the 14-bp ins/del polymorphism does not significantly contribute to hepatic injury. PMID- 27706616 TI - Investigation of the role of XRCC1 genetic polymorphisms in the development of gliomas in a Chinese population. AB - We conducted a study in a Chinese Han population to investigate the role of XRCC1 gene polymorphisms (Arg399Gln and Arg194Trp) with a risk of susceptibility to gliomas. Samples from 115 patients with gliomas and 228 control subjects were consecutively collected between March 2012 and December 2014. Genotype analysis of XRCC1 Arg399Gln and Arg194Trp was performed using polymerase chain reaction restriction fragment length polymorphism assay. All the analyses were performed using the SPSS 17.0 software package. We observed that the XRCC1 Arg399Gln and Arg194Trp genotype frequencies conformed to the Hardy-Weinberg equilibrium. We observed that the Trp/Trp genotype of XRCC1 Arg194Trp was associated with an increased risk of glioma when compared to the wild-type genotype (odds ratio (OR) = 2.14, 95% confidence interval (CI) = 1.14-3.86, P = 0.03). In the dominant model, we found that the Arg/Trp + Trp/Trp genotype of XRCC1 Arg194Trp could significantly elevate the susceptibility of developing glioma (OR = 1.79, 95%CI = 1.07-0.94). However, we observed that the XRCC1 Arg399Gln genetic polymorphism did not influence the risk of glioma. In summary, we suggest that the XRCC1 Arg194Trp genetic polymorphism could be a predictive biomarker for the susceptibility to glioma in a Chinese population. PMID- 27706618 TI - Identification of key biomarkers involved in osteosarcoma using altered modules. AB - The aim of this study was to screen for key biomarkers of osteosarcoma (OS) by tracking altered modules. Protein-protein interaction (PPI) networks of OS and normal groups were constructed and re-weighted using the Pearson correlation coefficient (PCC), respectively. The condition-specific modules were explored from OS and normal PPI networks using a clique-merging algorithm. Altered modules were identified by a maximum weight bipartite-matching method. The important biological pathways in OS were identified by a pathway-enrichment analysis using genes from disrupted modules. The most important genes in these pathways were selected as key biomarkers. Finally, the mRNA and protein expressions of hub genes in OS bone tissues were analyzed using reverse transcription-polymerase chain reaction and western blotting, respectively. We identified 703 and 2270 modules in normal and disease networks, respectively; 150 altered modules were identified from among these and explored. We identified 10 important pathways based on gene pairs with altered PCC > 1 in the disrupted modules (P < 0.01), and PCNA, ATP6V1C2, ATP6V1G3, FEN1, CDC7, and RPA3 (expressed in these pathways) were selected as key genes of OS. We observed that these genes (and the proteins they encoded) were differentially expressed between normal and OS samples (P < 0.01) (excluding ATP6V1C2, whose protein expression did not differ significantly). Therefore, we identified 5 gene signatures that may be potential biomarkers for the detection and effective therapy of OS. PMID- 27706617 TI - Correlation of VCAM-1 expression in serum, cord blood, and placental tissue with gestational hypertension associated with fetal growth restriction in women from Xingtai Hebei, China. AB - The aim of this study was to investigate the expression of vascular adhesion molecule (VCAM)-1 in the maternal serum, cord blood, and placental tissue of pregnant women from Xingtai, Hebei, with gestational hypertension (GH) combined with fetal growth restriction (FGR). A total of 108 patients with GH combined with FGR (GH-FGR), 60 patients with GH alone (GH), and 50 healthy pregnant women (control) were recruited to this study. VCAM- 1 expression was detected in the maternal serum and cord blood by enzyme-linked immunosorbent assay, and in the placental tissue by immunohistochemistry. VCAM-1 expression was significantly higher in the maternal serum of patients with GH-FGR (164.38 +/- 60.35) and GH alone (103.85 +/- 54.47) than in the serum of the control population (46.70 +/- 21.79; P < 0.05). On the other hand, VCAM-1 expression in the cord blood of GH FGR (163.19 +/- 69.46), GH (149.82 +/- 58.20), and control (128.89 +/- 43.59) subjects was not significantly different (P > 0.05). Moreover, the VCAM-1 expression rates were significantly higher and lower in the vascular endothelial and trophoblastic cells of the placenta of patients with GH-FGR (74.71 and 56.1%) and GH (72.98 and 55.36%), respectively, compared to those in the control subjects (46.48 and 95.11%). Therefore, we concluded that VCAM- 1 plays an important role in the development and generation of GH. Additionally, the low VCAM-1 expression in the trophoblastic cell could be correlated to the pathogenesis and progression of GH. PMID- 27706619 TI - Assessing the association between EFEMP1 rs3791679 polymorphism and risk of glioma in a Chinese Han population. AB - In this study, we assessed the association between the EFEMP1 rs3791679 polymorphism and glioma risk in a Chinese Han population. A total of 94 glioma patients and 206 healthy controls who conformed to the inclusion and exclusion criteria were recruited from Baogang Hospital between March 2012 and October 2014. The EFEMP1 rs3791679 gene polymorphism was assessed using a polymerase chain reaction-restriction fragment length polymorphism assay and the results were statistically analyzed using SPSS Statistics 17.0. The results of unconditional logistic regression analysis revealed that the GG genotype of EFEMP1 rs3791679 was positively correlated with increased susceptibility to glioma (adjusted OR = 2.09, 95%CI = 1.21-7.81). Moreover, the GG genotype of EFEMP1 rs3791679 was correlated with higher risk of glioma compared to the AA+GA genotype (OR = 2.60, 95%CI = 1.08-6.28) in the regressive model. In conclusion, we report that the EFEMP1 rs3791679 polymorphism influences glioma susceptibility in the Chinese Han population. PMID- 27706620 TI - New chromosomal evidence for the origin of Triatoma infestans populations from Brazil. AB - In this study, the karyometry of different Triatoma infestans populations from different states of Brazil was analyzed and compared with those of a population from Cochabamba. No significant differences were found between the population from Cochabamba and those from Brazil. These results are consistent with the origin of the T. infestans populations of Brazil by a founder effect from Cochabamba. Moreover, these findings also confirm that a founder effect occurred during the dispersal of T. infestans populations in different Brazilian states. PMID- 27706622 TI - Investigation on ERCC5 genetic polymorphisms and the development of gastric cancer in a Chinese population. AB - Our study aimed to investigate the role of 2 ERCC5 promoter SNPs (rs2094258 and rs751402) in the development of gastric cancer in the Chinese population. The present hospital-based case-control study consisted of 155 patients with gastric cancer and 246 healthy controls recruited between March 2012 and December 2014. Genotyping for the rs2094258 and rs751402 polymorphic sites was carried out using polymerase chain reaction-restriction fragment length polymorphism. Statistical analyses were conducted using the SPASS version 16.0 software (SPSS, Inc., Chicago, IL, USA). As determined by the chi-square test, there was a significant difference in the genotype distributions of rs751402 between patients and controls (X2 = 6.74, P = 0.03). By unconditional logistic regression analysis, we observed that the TT genotype in rs751402 was significantly associated with increased risk to gastric cancer as compared with the CC genotype, and the adjusted OR (95%CI) was 2.17 (1.15-4.09). Moreover, subjects carrying the T allele in rs751402 had elevated risk of developing gastric cancer when compared with those carrying the C allele, with an adjusted OR value (95%CI) of 1.47 (1.09 1.99). In conclusion, we suggest that the ERCC5 rs751402 gene polymorphism may influence the susceptibility to gastric cancer in the Chinese population. PMID- 27706621 TI - Low levels of serum miR-99a is a predictor of poor prognosis in breast cancer. AB - MicroRNA (miRNA) deregulation has been previously linked to the initiation and development of breast cancer. Although miR-99a is aberrantly expressed in many types of cancers, including breast cancer, the serum miR-99a expression level in breast cancer and its clinical significance remains unknown. Blood samples were obtained from 72 patients with breast cancer and 40 healthy volunteers, and subjected to real-time polymerase chain reaction to evaluate the level of expression of serum miR-99a in the study participants. Furthermore, we investigated the association between serum miR-99a and the clinical outcome of breast cancer. Serum miR-99a expression was significantly downregulated in patients with breast cancer, compared to that in healthy controls (P < 0.01). Moreover, the serum miR-99a was correlated with various clinical parameters of breast cancer, including lymph node metastasis (P = 0.0194), distant metastasis (P = 0.0037), Ki67 intensity (P = 0.0164), TNM stage (P = 0.0096), and histological grade (P = 0.0051) of cancer. Additionally, breast cancer patients displaying lower miR-99a levels showed poorer overall survival rates (P = 0.0411). The serum miR-99a level was also found to be an independent risk factor for breast cancer (hazard ratio = 3.176, 95% confidence interval = 1.543-7.360, P = 0.023). Our data indicated that serum miR-99a expression was downregulated in breast cancer patients; moreover, this downregulation was associated with poor prognosis, suggesting that serum miR-99a could function as a tumor suppressor in breast cancer. PMID- 27706623 TI - Development and significance of SCAR marker QG12-5 for Canarium album (Lour.) Raeusch by molecular cloning from improved RAPD amplification. AB - Sequence-characterized amplified region (SCAR) is a valuable molecular marker for the genetic identification of any species. This marker is mainly derived from molecular cloning of random amplified polymorphic DNA (RAPD). We have previously reported the use of an improved RAPD technique for the genetic characterization of different samples of Canarium album (Lour.) Raeusch (C. album). In this study, DNA fragments were amplified using improved RAPD amplified from different samples of C. album. The amplified DNA fragment was excised, purified from an agarose gel and cloned into a pGM-T vector; subsequently, a positive clone, called QG12-5 was identified by PCR amplification and enzymatic digestion and sequenced by Sanger di-deoxy sequencing method. This clone was revealed consisting of 510 nucleotides of C. album. The SCAR marker QG12-5 was developed using specifically designed PCR primers and optimized PCR conditions. This SCAR marker expressed seven continuous "TATG" [(TATG)n] tandem repeats, which was found to characterize C. album. Subsequently, this novel SCAR marker was deposited in GenBank with accession No. KT359568. Therefore, we successfully developed a C. album-specific SCAR marker for the identification and authentication of different C. album species in this study.

It is characterized by the presence of endometrial-like tissues outside of the uterus. Some definitions claim that the functional ectopic tissue is sensitive to the action of hormones. Severity of endometriosis is defined according to a system proposed by the American Society for Reproductive Medicine, which is based on laparoscopic findings. A large number of genetic polymorphisms has been reported for CYP1A1, the gene that is responsible for enzymes involved in stage I detoxification of xenobiotics; this gene is located at 15q22-24, and encodes an isoenzyme that catalyzes the oxidation of polycyclic aromatic hydrocarbons present in phenolic compounds and epoxides. The aim of this study was to analyze the frequency of the MspI polymorphism and its relation to endometriosis. We obtained peripheral blood samples from 52 women with endometriosis (confirmed by laparoscopy) as well as 42 women without endometriosis (control group). In the case group, the women were between 25 and 35 years of age; the age range was between 25 and 57 years old in the control group. Molecular analysis was performed by polymerase chain reaction. We found a significant association (P = 0.039) between the polymorphic allele m1 and endometriosis (32.70%). In conclusion, this study showed that the m1 polymorphism is associated with endometriosis, and that W1/m1 and m1/m1 polymorphisms are more frequently observed in patients with infertility and severe endometriosis.

AB - We investigate the relationship between IL-18 -607C/A and -137G/C genetic polymorphisms and development of acute pancreatitis in a Chinese population. A total of 153 patients were consecutively recruited from the First Affiliated Hospital of Chongqing Medical University between January 2013 and November 2014. Genotyping of IL-18 -607C/A and -137G/C variants was performed using the polymerase chain reaction-restriction fragment length polymorphism method. We observed a significant difference between acute pancreatitis patients and control subjects with respect to age (t = 2.15, P = 0.02), gender (chi-square = 3.95, P = 0.04), body mass index (t = 5.85, P < 0.001), and alcohol consumption (chi-square = 9.74, P = 0.002). Using chi-square tests, we found that the genotype distributions of IL-18 -607C/A (chi-square = 0.81, P = 0.67) and -137G/C (chi square = 1.16, P = 0.56) polymorphisms did not differ between the acute pancreatitis and control groups. Genotype frequencies of these variants were consistent with Hardy-Weinberg equilibrium in both patient and control groups. In addition, logistic regression analysis failed to identify a significant association between these polymorphisms and acute pancreatitis risk. Our study firstly examined their association in a Chinese population, and we suggest that the IL-18 -607C/A and -137G/ C polymorphisms do not influence susceptibility to acute pancreatitis in the Chinese population studied in the present study. PMID- 27706626 TI - Growth hormone polymorphisms and growth traits in Chinese Tibetan sheep Ovis aries. AB - Growth hormone (GH) plays an important role in promoting growth, protein and muscle accretion, and fat catabolism, suggesting that GH is a potential candidate gene affecting growth traits in vertebrates. In this paper, polymorphisms in GH were investigated in 632 Chinese Tibetan sheep, by using DNA sequencing. Three single nucleotide polymorphisms were identified, including two mutations (g.616G>A and g.624G>A) in intron 2 and one synonymous mutation (g.498G>C) in exon 2. Association analyses showed that both g.498G>C and g.616G>A were significantly associated with several growth traits (at P < 0.01 or P < 0.05) in three investigated breeds. Our results demonstrate that GH variation may be used as a molecular marker for growth traits in Chinese Tibetan sheep. PMID- 27706627 TI - Development of polymorphic microsatellite loci in Odontobutis obscura using Illumina paired-end sequencing and the test of cross-species amplification. AB - Odontobutis obscura is a bottom-dwelling freshwater fish native to East Asia. Its range encompasses southwest China, western Japan, and Geoje Island in South Korea. Despite its widespread range in China and Japan, only a small and spatially isolated population is found in South Korea. We developed a total of 23 novel and polymorphic microsatellite loci of O. obscura using Illumina paired-end shotgun sequencing and characterized them using 80 Japanese and Korean samples. An extensive genetic polymorphism was detected at these 23 loci, with the observed number of alleles at a locus ranging from 2 to 15 and expected and observed heterozygosities ranging from 0 to 0.656 and 0 to 0.547, respectively. Korean O. obscura exhibited a much lower level of genetic variability than the Japanese population did, probably as a result of long-term isolation combined with historical bottlenecks. The Japanese and Korean populations showed a high level of genetic differentiation with FST = 0.700 and RST = 0.913. Many of our primer sets were successfully transferable to congeneric O. interrupta and O. platycephala, which exhibited even greater polymorphism than Korean O. obscura. In conclusion, our study showed that these 23 microsatellite markers are useful for understanding the conservation biology and population genetic structure of O. obscura and other congeneric species. PMID- 27706628 TI - Association between TNF-alpha rs1800629 polymorphism and the risk of myocardial infarction: A meta-analysis. AB - The tumor necrosis factor-alpha (TNF-alpha) G-308A polymorphism has been suggested to be a susceptibility factor for myocardial infarction (MI). However, differing results from various studies have led to controversial conclusions. Hence, we performed a meta-analysis to evaluate the association between TNF-alpha G-308A polymorphism and MI. Reported studies published before March 30, 2015 were included and analyzed from the PubMed and Embase databases. Study selection and data extraction were carried out independently by two authors. The odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the association between the selected variables using the Comprehensive Meta-Analysis v2.2 software. In total, 12 publications with 13 case-control studies consisting of 6037 cases and 7262 controls were included in our meta-analysis. The overall results showed that there was no significant association between TNF-alpha G-308A polymorphism and MI risk [A vs G: OR = 1.18, 95%CI = 0.94-1.48; AA vs GG: OR = 1.23, 95%CI = 0.74-2.05; GA vs GG: OR = 1.22, 95%CI = 0.98-1.51; (GA+AA) vs G: OR = 1.21, 95%CI = 0.96-1.54; AA vs (GG+GA): OR = 1.16, 95%CI = 0.72-1.88]. However, when subgroup analysis was performed according to the stages of MI, results indicated that there was a significant association between TNF-alpha G-308A polymorphism and the risk of acute MI. Other subgroup analyses revealed no significant associations. Current evidence suggests that TNF-alpha G-308A polymorphism may be associated with increased risk for acute MI. PMID- 27706629 TI - Trans-translation ensures timely initiation of DNA replication and DnaA synthesis in Escherichia coli. AB - The trans-translation pathway, mediated by the transfer messenger RNA (tmRNA; encoded by the ssrA gene) and the SmpB protein (tmRNA-binding protein expressed in Salmonella enterica), which is conserved in bacteria, is required for various cellular processes. A previous study has shown that trans-translation is required to ensure timely (non-delayed) dnaA transcription and consequent initiation of DNA replication in Caulobacter crescentus. In this study, we observed that initiation of chromosome replication was delayed in Escherichia coli lacking the smpB and/or ssrA genes (DssrA, DsmpB, or DsmpBDssrA mutants). We observed that the growth rate of the mutant cells was much slower than that of its wild-type counterpart. However, the delayed initiation of replication and slower growth in the DssrA or DsmpB mutants were reversed by ectopic expression of tmRNA or SmpB. A synchronized DsmpBDssrA cell culture containing the dnaC2 mutant allele showed delayed protein (total and DnaA) accumulation per cell; DnaA accumulation was also delayed in the DsmpB. These results indicated that absence of trans translation leads to a delay in initiation of DNA replication, synthesis of total protein (including DnaA), and a decrease in E. coli growth rate. In summary, we propose that the trans-translation pathway is required to ensure timely initiation of replication, protein synthesis, and subsequent cell cycle progression. PMID- 27706630 TI - Simulating the selfing and migration of Luehea divaricata populations in the Pampa biome to investigate the conservation potential of their genetic resources. AB - Computer simulations are an important tool for developing conservation strategies for forest species. This study used simulations to investigate the genetic, ecological, and reproductive patterns that contribute to the genetic structure of the tree Luehea divaricata Mart. & Zucc. in five forest fragments in the Brazilian Pampa biome. Using the EASYPOP model, we determined the selfing and migration rates that would match the corresponding genetic structure of microsatellite marker data (based on observed and expected heterozygosity parameters). The simulated reproductive mode was mixed, with a high rate of outcrossing (rate = 0.7). This was consistent with a selfing-incompatible system in this species, which reduced, but did not prevent, selfing. The simulated migration rate was 0.02, which implied that the forest fragments were isolated by distance, and that the inbreeding coefficients were high. Based on Nei's gene diversity analysis, 94% of the genetic variability was distributed within the forest fragments, and only 6% of the genetic diversity was caused by differences between them. Furthermore, the minimum viable population and minimum viable area genetic conservation parameters (which determine conservation potential in the short and long term) suggested that only the Inhatinhum forest fragment had the short-term potential to maintain its genetic diversity. However, in the long term, none of the forest fragments proved to be sustainable, indicating that the populations will require intervention to prevent a decline in genetic variability. The creation of ecological corridors could be a useful solution to connect forest fragments and enhance gene flow between them. PMID- 27706631 TI - Effect of UBE3C polymorphisms on intramuscular fat content and fatty acid composition in Duroc pigs. AB - Ubiquitin protein ligase E3C (UBE3C) is involved in the ubiquitin-proteasome pathway, and several ubiquitin protein ligases are important for fat deposition and lipid metabolism. The objective of this study was to analyze the association between a single nucleotide polymorphism (SNP) of the UBE3C gene with intramuscular fat (IMF) content and fatty acid (FA) composition in Duroc pigs. Four SNP markers (g.1586399A>G, g.1591358G>A, g.1600132G>C, and g.1600166G>A) of porcine UBE3C were genotyped using the polymerase chain reaction-restriction fragment length polymorphism method, and their associations with IMF content and FA composition were investigated in a commercial Duroc pig population. Two SNP markers (g.1586399A>G and g.1591358G>A) were segregated among the pigs. No UBE3C polymorphisms at g.1600132G>C or g.1600166G>A were observed. The UBE3C g.1586399A>G SNP was significantly associated with IMF content, while the UBE3C g.1591358G>A SNP was associated with palmitic, stearic, eicosenoic, and eicosadienoic acid levels, and saturated FA levels. These results suggest that polymorphisms in porcine UBE3C are correlated with IMF content and FA composition, and confirm the importance of porcine UBE3C as a candidate gene for fat deposition in pigs. PMID- 27706632 TI - High levels of glucose promote the activation of hepatic stellate cells via the p38-mitogen-activated protein kinase signal pathway. AB - The relationship between the p38-mitogen-activated protein kinase (p38-MAPK) signal pathway and high glucose-induced hepatic stellate cell (HSC) activation was investigated in this study. Sixty human HSC samples were randomly selected and used in the control (cultured normally), high-glucose (cultured in the presence of high glucose), and blocking (cultured under high-glucose conditions in the presence of the p38-MAPK inhibitor, SB203580) groups. The cells were incubated for 120 h and subsequently analyzed for morphological changes by inverted microscopy and for a-smooth muscle actin (a-SMA) expression (to determine the degree of HSC activation) by the method of streptavidin-biotin complex and western blot. Phospho-p38-MAPK protein expression was analyzed by western blotting. a-SMA and phospho-p38-MAPK expression was significantly upregulated in HSCs cultured under high-glucose conditions, compared to the HSCs cultured normally (P < 0.01). On the other hand, phospho-p38-MAPK and a-SMA protein levels were significantly lower in the blocking group compared to the high-glucose group (P < 0.01). Based on these results, we concluded that high glucose levels induce HSC activation mediated by phospho-p38-MAPK. Therefore, blocking the p38-MAPK signal pathway could inhibit this effect. PMID- 27706633 TI - Correlative study between the JAK2V617F mutation and thrombosis in patients with myeloproliferative neoplasm. AB - In this study, we investigated the correlation between the JAK2V617F mutation and thrombosis in patients with myeloproliferative neoplasm (MPN) using real-time fluorescence quantitative PCR. The incidence of thrombus was monitored and blood and coagulation were routinely assayed in patients with MPN. The JAK2V617F mutation was found in 8/68 individuals in the control group (11.8%); it was expressed in 44/68 patients with MPN (64.7%), suggesting that the rate of this mutation was significantly higher in patients with MPN than that in the control group. Twenty-six MPN patients (38.2%) showed symptoms of thrombosis; MPN patients with thrombosis showed a significantly higher rate of the JAK2V617F mutation, were of a greater age, and had higher blood pressure than MPN patients without thrombosis. In addition, the white blood cells (WBC) (21.98 +/- 1.95) and platelets (364.68 +/- 97.72) were significantly higher in patients, expressing the mutated gene, with polycythemia vera than in the patients without the mutation. The WBC (32.89 +/- 4.25) and hemoglobin (161.92 +/- 16.19) were significantly increased in the essential thrombocythemia patients with gene mutation compared with the patients without mutation. MPN patients showed higher blood clotting ability than the control subjects; moreover, MPN patients with the JAK2V617F mutation showed higher blood clotting ability than those without the mutation. The findings of this study indicate that the JAK2V617F mutation is correlated with the incidence of thrombosis, and analysis of this mutation has important clinical significance in the diagnosis and treatment of MPN. PMID- 27706634 TI - Kallikrein 12 downregulation reduces AGS gastric cancer cell proliferation and migration. AB - Abnormal expression of the kallikrein (KLK) family of serine proteases closely correlates with onset, progression, and prognosis of endocrine gland-related malignant tumors. The aim of this study was to evaluate how downregulation of KLK12 influenced cell cycle and proliferation of the AGS gastric cancer cell line. KLK12 was detected by western blot in GES-1 normal gastric epithelial and AGS cells. AGS cells were transfected with KLK12 siRNA, a negative control siRNA, or subjected to a mock transfection, following which, we assessed mRNA and protein levels, cell proliferation, cell migration, and cell cycle progression. We found that KLK12 levels were significantly higher in AGS cells than in GES-1 cells. Transfection of AGS cells with KLK12 siRNA led to downregulation of KLK12 mRNA and protein expression, reduced cell proliferation (0.47 +/- 0.03 vs 0.92 +/ 0.04, P < 0.01), and lower cell counts (3.92 +/- 0.25 x 105 vs 5.47 +/- 0.50 x 105, P < 0.01) with respect to the negative control. We observed that KLK12 siRNA increased the number of AGS cells in G0/G1 and reduced those in S phase. Furthermore, downregulation of KLK12 in AGS cells decreased their ability to penetrate the membrane in a migration assay (P < 0.05). In conclusion, KLK12 siRNA inhibited the proliferation and migration of AGS gastric cancer cells and caused their arrest in the G0/G1 phase of the cell cycle. PMID- 27706635 TI - miR-146a and miR-196a2 polymorphisms in ovarian cancer risk. AB - We investigated the relationship between miR-146a and miR-196a2 genetic polymorphisms and development of ovarian cancer in a Chinese population. A total of 134 patients and 227 control subjects were involved in our study between January 2012 and October 2014 from China-Japan Union Hospital of Jilin University. Genotyping of miR-146a and miR-196a2 was accomplished by polymerase chain reaction coupled with restriction fragment length polymorphism analysis. Unconditional multiple-logistic regression analysis indicated that the GG genotype of miR-146a was associated with an increased risk of ovarian cancer when compared to the CC genotype, and the adjusted OR (95%CI) was 3.73 (1.79-7.80). Moreover, the CG+GG genotype of miR-146a was associated with an increased risk of ovarian cancer compared with the CC genotype (OR = 1.68, 95%CI = 1.06-2.66), and the GG genotype had a higher risk of ovarian cancer than the CC+CG genotype (OR = 3.02, 95%CI = 1.55-5.98). In conclusion, our study suggests that the miR-146a polymorphism is associated with increased risk of ovarian cancer and could be used as a biomarker for ovarian cancer susceptibility. PMID- 27706636 TI - DNA barcoding reveals high levels of genetic diversity in the fishes of the Itapecuru Basin in Maranhao, Brazil. AB - DNA barcoding is a useful complementary tool for use in traditional taxonomic studies due to its ability to detect cryptic species, and may be particularly efficient in the identification of fish species. The fish fauna of the Itapecuru River represents an important fishery resource in the Brazilian State of Maranhao, although it is currently suffering increasing degradation as a result of anthropogenic impacts. Therefore, DNA barcoding was used in the present study to identify fish species and establish a database of the rich freshwater fish fauna of Maranhao. A total of 440 specimens were analyzed, corresponding to 64 species belonging to 59 genera, 31 families, and 10 orders. Overall, 92.19% of these species could be identified by DNA barcoding, and were characterized by low levels (average 0.80%) of intra-specific divergence. However, five species (Anableps anableps, Gymnotus carapo, Sciades couma, Pseudauchenipterus nodosus, and Leporinus piau) presented values of mean genetic divergence above 3%, indicating the existence of cryptic diversity in these fishes. The DNA barcoding approach permitted the analysis of a large number of specimens and facilitated the discrimination and identification of closely related fish species in the Itapecuru Basin. PMID- 27706637 TI - MicroRNA variants and colorectal cancer risk: a meta-analysis. AB - Colorectal cancer (CRC) is a multi-factorial disease, and genetic background may contribute to its etiology. Single nucleotide polymorphisms (SNPs) in microRNAs (miRNAs) may be used as specific markers of predisposition for CRC diagnosis and prevention. In this review, we summarize and discuss recent publications evaluating the roles of miRNA SNPs in CRC. A meta-analysis was also carried out to assess the association between the five most frequently studied miRNA SNPs and CRC risk. No relationship was established between this disease and the three SNPs rs11614913, rs2910164, and rs3746444 in miR-196a-2, miR-146a, and miR-499, respectively. However, polymorphisms of miR-149 (rs2292832; CT vs TT: odds ratio [OR] = 0.816, 95% confidence interval [CI] = 0.691-0.963; CC+CT vs TT: OR = 0.834, 95%CI = 0.715-0.972) and pre-miR-27a (rs895819; GG vs AA: OR = 1.534, 95%CI = 1.148-2.049; GG+AG vs AA: OR = 1.324, 95%CI = 1.066-1.645) were found to be associated with CRC in our analysis. In conclusion, the SNPs rs2292832 in miR 149 and rs895819 in pre-miR-27a were associated with CRC susceptibility, whereas rs11614913, rs2910164, and rs3746444 in miR-196a-2, miR-146a, and miR-499, respectively, were not. Further studies should be carried out to validate these findings. PMID- 27706638 TI - Population genetic structure and its implication in the conservation of Schizopygopsis pylzovi in Yellow River as inferred from mitochondrial DNA sequence analysis. AB - To assess the genetic diversity, structure, and population dynamics of Schizopygopsis pylzovi, we examined the changes in mitochondrial DNA sequences (the mtDNA control region and the Cyt b gene; 1835 bp) in 304 individuals from nine populations. The samples were segregated into 112 haplotypes, with high haplotype diversity and low nucleotide diversity. The haplotype diversity was highest in the Minhe (HS) range of Huangshui River and lowest in the Weiyuan (WY) range of Weihe River. Analysis of molecular variance showed that 69.64% of the total genetic variance was contributed by within-the-group variation and 30.36% was contributed by among-the-group variation. Pairwise FST revealed significant divergence between the populations. The FST between the MT and WY was highest, and that between the YZ and YJ was lowest. The neighbor-joining phylogenetic tree demonstrated that all geographic populations were not monophyletic, but overlapped each other, indicating that the duration of geographical isolation was not long enough or the populations had not yet reached significant genetic isolation or differentiation at the monophyletic level. Tajima's D and Fu's Fs were negative and statistically significant, indicating that S. pylzovi had experienced certain population expansion events, which is consistent with the hypothesis that the headwater area of the Yellow River was dramatically affected by the geological and climatic upheaval during the Quaternary ice age. Our analysis indicated that the management units corresponding to the WY population should be managed and conserved first. In situ conservation is first recommended to protect the original habitat from further destruction. PMID- 27706639 TI - Molecular characterization and upregulation of cytosolic manganese superoxide dismutase by imidazole derivative KK-42 in Macrobrachium nipponense. AB - Imidazole derivative KK-42 is a well-known regulator of insect growth. KK-42 pretreatment has been shown to promote the survival of Macrobrachium nipponense infected with Aeromonas hydrophila, possibly via activation of superoxide dismutase (SOD). In this study, the cytMnSOD gene was cloned from the hepatopancreas of M. nipponense using the rapid amplification of cDNA ends technique. The full-length cDNA of cytMnSOD was 1233 bp long, and the open reading frame was 858 bp long, encoding a 286-aa protein with a 60-aa leader sequence. The calculated molecular mass of the translated cytMnSOD protein was 31.33 kDa, with an estimated isoelectric point of 5.62. cytMnSOD contained two N glycosylation sites, four conserved amino acids responsible for binding manganese, and a manganese SOD domain (DVWEHAYY). Real-time RT-PCR analysis showed that cytMnSOD was expressed in all tissues examined with the highest expression observed in the hepatopancreas. Levels of the cytMnSOD transcript in the hepatopancreas were highest in stage C of the molting cycle. Real-time PCR analysis revealed that cytMnSOD expression increased significantly 3, 6, and 12 h after KK-42 treatment, with simultaneous increases in SOD activity from 6 to 12 h. Our results demonstrate that cytMnSOD expression and SOD activity may be induced by KK-42, which may represent one of the molecular mechanisms through which KK-42 promotes increased survival of prawns infected with A. hydrophila. PMID- 27706640 TI - Characterization and evolution of the mitochondrial DNA control region in Ranidae and their phylogenetic relationship. AB - The control region is considered to be one of the most variable parts of animal mitochondrial DNA (mtDNA). We compared the mtDNA control region from 37 species representing 14 genera and 4 subfamilies of Ranidae, to analyze the evolution of the control region and to determine their phylogenetic relationship. All the Ranidae species had a single control region, except four species that had two repeat regions. The control region spanned the region between the Cyt b and tRNAleu genes in most of the Ranidae species. The length of the control region sequences ranged from 1186 bp (Limnonectes bannaensis) to 6746 bp (Rana kunyuensis). The average genetic distances among the species varied from 1.94% (between R. chosenica and R. plancyi) to 113.25% (between Amolops ricketti and Euphlyctis hexadactylus). The alignment of three conserved sequence blocks was identified. However, conserved sequence boxes F to A were not found in Ranidae. A maximum likelihood method was used to reconstruct the phylogenetic relationship based on a general time reversible + gamma distribution model. The amount of A+T was higher than G+C across the whole control region. The phylogenetic tree grouped members of the respective subfamilies into separate clades, with the exception of Raninae. Our analysis supported that some genera, including Rana and Amolops, may be polyphyletic. Control region sequence is an effective molecular mark for Ranidae phylogenetic inference. PMID- 27706641 TI - Genetic diversity and population structure of Fenneropenaeus penicillatus determined by mitochondrial DNA analyses. AB - Fenneropenaeus penicillatus is a widely distributed economically and ecologically important shrimp species, which is endangered in China. Sequence analysis of 16s rRNA and control region (CR) fragments from mitochondrial DNA was conducted to obtain information on genetic diversity and population structure. Individuals from 12 wild F. penicillatus populations located along the southeast coast of China were used. Polymerase chain reaction (PCR) fragments of the CR gene revealed high genetic diversity among the 12 populations; however, PCR fragments of the 16s rRNA gene revealed very low genetic diversity in the Hainan (HN) and Ningde (ND) populations and high genetic diversity in the DS, BH, PT, XM, and SZ populations. Data obtained from the CR and 16s rRNA genes suggested that high genetic differentiation exists among the 12 populations, which is mainly due to the high genetic differentiation between HN and all other 11 populations. These results may be useful for further sustainable management and utilization of this species. PMID- 27706642 TI - Snail-induced epithelial-mesenchymal transition in gastric carcinoma cells and generation of cancer stem cell characteristics. AB - Biological changes in Snail-overexpressed SGC7901 cells were studied by establishing a pEGFP-C1-Snail carrier. The significance of Snail in epithelial mesenchymal transition (EMT) as well as the invasion and metastatic capacity of gastric cancer cells was also discussed; moreover, we attempted to verify the probable cancer stem cell characteristics of Snail-overexpressed cells. A pEGFP C1-Snail eukaryotic expression plasmid was constructed and pEGFP-C1(-) and pEGFP C1-Snail plasmids were extracted and transfected into SGC7901 cells using Lipofectamine 2000. Stably expressed SGC7901-N [control group containing pEGFP C1(-)] and SGC7901-S (test group containing pEGFP-C1-Snail) cells were screened using a G418 resistance medium. Snail, E-cadherin, b-catenin, vimentin, and fibronectin gene and protein expressions were detected by real-time quantitative PCR, western blot, and immunofluorescence. Cell invasion and metastasis were tested by scratch test, invasion assay, and an adhesion experiment. The positive rate of aldehyde dehydrogenase-1 (ALDH-1) expression was analyzed by flow cytometry. The results indicated the occurrence of EMT, accompanied by morphological changes in the cells and a weakening of the cell adhesion capacity. We also observed a decrease in the expression of epithelial markers E-cadherin and b-catenin and an increase in mesenchymal (Snail and vimentin) marker expression. Moreover, the cells showed increased invasiveness and metastatic capacity, and decreased proliferative ability. Moreover, the Snail-treated SGC7901 cells moved towards the scratch and produced fewer clones compared to the control cells. Owing to its capacity for self-renewal, SGC7901-S cells produced new clones and expressed ALDH-1. Therefore, we concluded that Snail overexpression induced EMT and endowed cells with tumor stem cell characteristics. PMID- 27706643 TI - Development of SNP-based dCAPS markers for identifying male sterile gene tms5 in two-line hybrid rice. AB - Molecular markers can increase both the efficiency and speed of breeding programs. Functional markers that detect the functional mutations causing phenotypic changes offer a precise method for genetic identification. In this study, we used newly derived cleaved amplified polymorphic sequence markers to detect the functional mutations of tms5, which is a male sterile gene that is widely used in rice production in China. In addition, restriction cutting sites were designed to specifically digest amplicons of tms5 but not wild type (TMS5), in order to avoid the risk of false positive results. By optimizing the condition of the polymerase chain reaction amplifications and restriction enzyme digestions, the newly designed markers could accurately distinguish between tms5 and TMS5. These markers can be applied in marker-assisted selection for breeding novel thermo-sensitive genic male sterile (TGMS) lines, as well as to rapidly identify the TGMS hybrid seed purity. PMID- 27706644 TI - Detection of Jaagsiekte sheep retrovirus in the peripheral blood during the pre clinical period of ovine pulmonary adenomatosis. AB - The envelope protein (Env) of the Jaagsiekte sheep retrovirus (JSRV) is known to be a unique oncoprotein responsible for inducing ovine pulmonary adenocarcinoma (OPA). The objective of this study was to prepare a specific monoclonal antibody (mAb) against the JSRV Env protein using bioinformatic analysis. According to the structure and epitope prediction results of JSRV Env, the JSRV-Env572-615 antigen was prepared via peptide synthesis (amino acid sequence 572-615, denoted as JSRV Env572-615). BALB/c mice were immunized to prepare the anti-JSRV-Env572-615 mAb. Spleen cells were fused with SP2/0 myeloma cells after being screened by indirect ELISA and cloned by limiting dilution. The specificity of mAb was evaluated by western blot analysis and immunohistochemistry assays. Western blot results showed that the JSRV Env protein was able to bind to mAb with high specificity. Immunohistochemistry assays demonstrated that the mAb was able to recognize JSRV Env in adenomatous hyperplasia of the lung. Furthermore, JSRV was detected in peripheral blood leukocytes during the pre-clinical period of OPA in 2 of the 25 sheep using this newly synthesized mAb. Therefore, this mAb may be a useful tool for the detection of JSRV in sheep. PMID- 27706645 TI - Twisting of the spermatic cord: ischemia and reperfusion, toxicogenetic evaluation, and the effects of phosphatidylcholine in pre-clinical trials. AB - Phosphatidylcholine is the main phospholipid present in cell membranes and in lipoproteins, and can interfere with various biological processes. This lipid also has antioxidant activity, and protects against damage caused by free radicals under conditions of ischemia/reperfusion. Therefore, the present study was designed to evaluate toxicogenetic damage caused by twisting of the spermatic cord in ischemia/reperfusion, and whether phosphatidylcholine plays a role in conditions of ischemia/reperfusion in preclinical trials. The results indicate that spermatic cord torsion does not cause genotoxic damage or mutagenesis. A dose of 300 mg/kg of phosphatidylcholine is toxic and is thus not recommended. However, a dose of 150 mg/kg does not promote toxicogenetic damage, and though it does not statistically prevent tissue damage occurring from lack of oxygenation and nutrition of testicular cells, it has a tendency to reduce this damage. Therefore, this research suggests that further studies should be conducted to clarify this tendency and to provide a better explanation of the possible therapeutic effects of phosphatidylcholine in cytoprotection of germ cells affected by ischemia/reperfusion.

AB - Ferritin is a conserved iron-binding protein involved in host defense and cellular iron metabolism in most organisms. We investigated the expression profiles of two ferritin genes (designated HsFer-1 and HsFer-2) in the hemocytes, gonad, and hepatopancreas of Hyriopsis schlegelii, when challenged with bacteria and metal ions. HsFer gene transcription increased 1.8-7.7- and 1.9-6.1-fold in these tissues after stimulation with Staphylococcus aureus and Vibrio anguillarum, respectively. In addition, following exposure to Fe3+, expression of HsFer-1 and HsFer-2 was elevated by 1.5-6.1- and 3.6-10.1-fold, respectively. Levels of HsFer-1 and -2 mRNA also increased significantly after treatment with Cu2+ and Pb2+ at certain concentrations. Moreover, recombinant HsFer-1 and -2 were able to inhibit the growth of two strains of bacteria, and the former efficiently chelated Fe3+. From these results, we conclude that HsFer-1 and -2 may be involved in iron metabolism and immune defense by inhibiting the growth of bacteria. PMID- 27706647 TI - Molecular cloning and expression pattern of oriental river prawn (Macrobrachium nipponense) nitric oxide synthase. AB - Nitric oxide synthase (NOS) produces nitric oxide (NO) by catalyzing the conversion of l-arginine to l-citrulline, with the concomitant oxidation of nicotinamide adenine dinucleotide phosphate. Recently, various studies have verified the importance of NOS invertebrates and invertebrates. However, the NOS gene family in the oriental river prawn Macrobrachium nipponense is poorly understood. In this study, we cloned the full-length NOS complementary DNA from M. nipponense (MnNOS) and characterized its expression pattern in different tissues and at different developmental stages. Real-time quantitative polymerase chain reaction (RT-qPCR) showed the MnNOS gene to be expressed in all investigated tissues, with the highest levels observed in the androgenic gland (P < 0.05). Our results revealed that the MnNOS gene may play a key role in M. nipponense male sexual differentiation. Moreover, RT-qPCR revealed that MnNOS mRNA expression was significantly increased in post-larvae 10 days after metamorphosis (P < 0.05). The expression of this gene in various tissues indicates that it may perform versatile biological functions in M. nipponense. PMID- 27706648 TI - Allele- and parent-of-origin-specific effects on expression of the KCNJ11 gene: A candidate for meat tenderness in cattle. AB - In contrast to the Mendelian inheritance model, parental alleles can contribute unequally to gene expression, which may result in phenotypic variance among individuals and bias in the predicted additive effect of molecular markers associated with production traits. Given the need to understand the effects of allelic variation and parent-of-origin effects on the expression of genes with a commercial interest in cattle, we analyzed the expression of KCNJ11 (potassium inwardly rectifying channel, subfamily J, member 11), which was previously described as a functional candidate gene for meat tenderness. Allele-specific and parent-of-origin-dependent expression of this gene were assessed in bovine muscle using the rs379610823 single nucleotide polymorphism as a reference. Biallelic expression was observed; however, the T allele was expressed at significantly higher levels than the C allele. Furthermore, increased expression of KCNJ11 was found in animals harboring the maternal T allele. This study is the first to describe the differential allelic expression of bovine KCNJ11. Our findings are important for understanding the mechanisms that underlie the pattern of KCNJ11 expression and its potential impact on the phenotypic variation of meat tenderness in Nelore beef cattle. This reinforces the need for further investigation of allelic- and parent-of-origin expression deviation in genetic markers eligible for the selection of target traits. PMID- 27706649 TI - Effect of 1,25-(OH)2D3 and lipopolysaccharide on mononuclear cell inflammation in type 2 diabetes mellitus and diabetic nephropathy uremia. AB - The prevention and treatment of type-2 diabetes mellitus (T2DM) and diabetic nephropathy (DN), which are disorders with high incidence rates, is of primary importance. In this study, we analyzed the effect of 1,25-(OH)2D3 and lipopolysaccharide (LPS) in combination with interleukin (IL)-15 on the inflammatory immune response and expression of vitamin D receptor (VDR) in mononuclear cells of T2DM and DN uremia (DNU) patients. The human acute monocytic leukemia cell line THP-1 was treated with peripheral blood serum isolated from 30 healthy controls and T2DM and DNU patients each, cultured in the presence or absence of 1,25-(OH)2D3, and subsequently treated with LPS and IL-15. The VDR mRNA and protein expression in THP-1 cells was detected by real-time polymerase chain reaction and western blot (and immunofluorescence assay), respectively, and IL-6 and IL-10 concentrations in the culture supernatant were detected by enzyme linked immunosorbent assay. LPS treatment induced a significant decrease in VDR mRNA expression in T2DM and DNU serum-treated THP-1 cells compared to the control cells (P < 0.05). The VDR protein expression in DNU serum-treated THP-1 cells was also significantly down-regulated (P < 0.05). LPS treatment induced IL-6 secretion in serum-treated THP-1 cells (P < 0.05), while 1,25-(OH)2D3 treatment inhibited IL-6 secretion to some extent. These findings suggested that LPS down regulates the expression of VDR in mononuclear cells of T2DM and DNU patients and induces an imbalance in the pro-inflammatory and anti-inflammatory cytokine response, while 1,25-(OH)2D3 partially reversed the effect of LPS and protected patients with T2DM and DNU. PMID- 27706650 TI - Association between -1082G/A, -819C/T, and -592C/A genetic polymorphisms in IL-10 and risk of type 2 diabetes mellitus in a Chinese population. AB - Type 2 diabetes mellitus is the most common form of endocrine disease in humans; genetic factors are known to contribute to the development of this disease. In this case-control study, we investigated the relationship between the -1082G/A, 819C/T, and -592C/A polymorphisms in interleukin 10 (IL-10) and the pathogenesis of type 2 diabetes mellitus in a Chinese population. Patients with type 2 diabetes mellitus (N = 228) and control subjects (N = 240) were recruited from the Department of Endocrinology at the People's Hospital of Linyi City, between September 2013 and April 2015. The IL-10 -1082G/A, -819C/T, and -592C/A polymorphisms were genotyped by polymerase chain reaction-restriction fragment length polymorphism. Multivariate logistic regression analyses revealed that patients carrying the AA genotype of IL-10 -592C/A were at a higher risk of developing type 2 diabetes mellitus compared to those carrying the CC genotype [adjusted odds ratio (OR) = 1.74; 95% confidence interval (CI) = 1.03-2.95]. In addition, individuals carrying the A allele of IL-10 -592C/A showed a 1.34-fold higher risk of developing type 2 diabetes mellitus compared to those carrying the C allele (adjusted OR = 1.34; 95%CI = 1.03- 1.75). There was no significant correlation between the IL-10 -1082G/ A and -819C/T polymorphisms and risk of type 2 diabetes mellitus. In conclusion, this study shows that the -1082G/A polymorphism of IL-10 contributes to the onset of type 2 diabetes mellitus, and may be considered a biomarker for early screening of type 2 diabetes mellitus in the Chinese population studied here. PMID- 27706651 TI - Promoter methylation and histone modifications affect the expression of the exogenous DsRed gene in transgenic goats. AB - Transgene silencing, which is common in transgenic plants and animals, limits the generation and application of genetically modified organisms, and is associated with the exogenous gene copy number, the methylation status of its promoters, and histone modification abnormalities. Here, we analyzed the expression of the exogenous gene DsRed and the methylation status of its cytomegalovirus (CMV) promoter in six healthy transgenic cashmere goats and transgenic nuclear donor cells. The CMV promoter exhibited high methylation levels (74.4-88.2%) in four of the goats, a moderate methylation level (58.7%) in one, and a low methylation level (21.2%) in one, while the methylation level of the transgenic nuclear donor cells was comparatively low (14.3%). DsRed expression was negatively correlated with promoter methylation status. Transgenic cashmere goats carried one to three copies of the CMV promoter fragment and one to six copies of the DsRed fragment, but copy number showed no obvious correlation with DsRed expression. After treatment with the methylation inhibitor 5-azacytidine, DsRed expression in transgenic goat cells significantly increased and CMV promoter methylation significantly decreased; this indicated an inverse correlation between promoter methylation status and DsRed expression. After treatment with the histone deacetylase inhibitor trichostatin A, DsRed expression increased, indicating that an abnormal histone modification in transgenic goats is also involved in exogenous gene silencing. These findings indicate the potential of trichostatin A and 5-azacytidine to rescue the biological activity of silenced exogenous transgenes in adult-derived transgenic cells under culture conditions. PMID- 27706652 TI - Identification of low potassium stress-responsive proteins in tobacco (Nicotiana tabacum) seedling roots using an iTRAQ-based analysis. AB - Potassium is one of the three main mineral nutrients, and is vital for leaf growth and the quality of tobacco (Nicotiana tabacum) plants. In recent years, the isobaric tags for relative and absolute quantitation (iTRAQ) method has been one of the most popular techniques for quantitative proteomic analysis. In this study, we used iTRAQ to compare protein abundances in the roots of control and low potassium-treated tobacco seedlings, and found that 108 proteins were differentially expressed between the two treatments. Of these, 34 were upregulated and 74 were downregulated, and 39 (36%) were in the chloroplasts. Kyoto Encyclopedia of Genes and Genomes pathway enrichment results suggested that metabolic pathways were the dominant pathways (10 upregulated and 14 downregulated proteins). Ten proteins involved in the pyruvate metabolism pathway increased their expression levels, and 17 upregulated proteins were enriched in the ribosomes category. To evaluate correlations between protein and gene transcript abundances, the expression patterns of 12 randomly chosen genes were examined. A quantitative real-time polymerase chain reaction revealed that the 12 genes were induced after low potassium treatment for 3, 6, 12, and 24 h. Our results demonstrate that low potassium levels affect protein profiles in tobacco roots. PMID- 27706653 TI - Diallel analysis to choose parents for black bean (Phaseolus vulgaris L.) breeding. AB - In this study, conducted in two different seasons, we aimed to choose parents to obtain promising segregating populations for the extraction of black bean (Phaseolus vulgaris L.) lines that are superior in terms of disease resistance, plant architecture, and grain yield. Twelve parents were arranged in two groups to compose a partial diallel in a 5 x 7 scheme. Group 1 was composed of parents with black grains and erect plant architecture, while group 2 was composed of parents that had carioca grains and were resistant to the main fungal diseases that occur in the common bean. The following traits were evaluated: severity of angular leaf spot (ALS), plant architecture (PAG), and grain yield (YIELD). The data were analyzed according to a partial diallel model using parents and F1 hybrids. In the genetic control of ALS and PAG, additive effects were predominant, while for YIELD, additive effects were predominant in one season and dominance effects were in another season, because it is a more complex trait than ALS and PAG. For YIELD, we observed an interaction between general combining ability and specific combining ability between seasons. The genes that control ALS, PAG, and YIELD were in eight of the 12 parents evaluated in the diallel. The cultivar 'BRS Estilo' is suitable to use as a parent in common bean breeding in terms of ALS, PAG and YIELD. Recurrent selection is the most recommended option for simultaneously breeding for PAG, YIELD, and resistance to angular leaf spot in bean culture. PMID- 27706655 TI - Transcriptome analysis of potential simple sequence repeat markers in Ammopiptanthus mongolicus. AB - Ammopiptanthus mongolicus, an evergreen broadleaf legume shrub, can survive under conditions of high and low temperature, extreme salinity, and drought. This attribute makes it an ideal model for studying mechanisms of stress tolerance in plants. However, simple sequence repeat (SSR) resources for this species are insufficient in public databases. In this study, a total of 44,959 unigenes identified from the A. mongolicus transcriptome were used for SSR analysis by MIcroSAtellite (MISA). A total of 13,859 SSRs were found to be distributed within 10,409 unigenes, with an average length of 15 bp and an average density of one SSR per 4.4 kb. There were 222 different motif types in the A. mongolicus transcriptome, and mononucleotide repeats represented the main type, accounting for 44.2% of all SSRs. The (A/T)n repeat was the most frequent motif, accounting for 42.37% of all SSRs. We also performed Gene Ontology functional analysis, Kyoto Encyclopedia of Genes and Genomes database pathway analysis, and eggNOG analysis, and identified 6157, 2301, and 9845 unigenes containing SSRs in these three databases, respectively. The functional categorization of A. mongolicus unigenes containing SSRs revealed that these unigenes represent many transcribed genes with different functions. These data provide sequence information that may be used to improve molecular-assisted markers for the study A. mongolicus genetic diversity. PMID- 27706654 TI - Characterization of the complete mitochondrial genome and phylogenetic relationships of the three-spot swimming crab (Portunus sanguinolentus). AB - In this study, we determined the whole mitochondrial genome profile of the three spot swimming crab (Portunus sanguinolentus) and elucidated phylogenetic relationships between representative species in the order Decapoda. The mitochondrial genome was 16,024 bp in length and consisted of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a putative control region. Of the 37 genes, 23 were encoded by the heavy strand while 14 were encoded by the light strand. Four types of start codons were identified; ATG initiated nine genes, ATT initiated two genes, and ATC and GTG each started one gene. Nine protein-coding genes ended with a complete TAA or TAG stop codon, and four genes ended with an incomplete T or TA codon. Fourteen non-coding regions were found, which ranged from 1 to 34 bp in length. Nine overlaps were observed, with lengths between 1 and 7 bp. Phylogenetic analysis suggested that P. sanguinolentus is genetically closest to P. trituberculatus and P. pelagicus. Charybdis feriata, C. japonica, and Thalamita crenata formed a single cluster, and were close to the genera Callinectes and Portunus. Therefore, the genera Charybdis and Thalamita should be classified into the subfamily Portuninae. PMID- 27706656 TI - Evaluation of serum HGF and CK18 levels in patients with esophageal cancer. AB - Cytokeratins are thought to play a role in apoptosis. Cytokeratin 18 (CK18) is involved in the formation of intracellular cytoskeleton, and has been considered a promising apoptosis marker in gastrointestinal carcinomas. Growth factors, including hepatocyte growth factor (HGF), may provide a microenvironment for malignant cells. In this study, we aimed to compare serum HGF and CK18 levels between esophageal squamous cell carcinoma patients and healthy controls. The study included 41 adult patients (20 male, 21 female) diagnosed with esophageal squamous cell carcinoma, with a mean age of 63.54 +/- 10.88 years (range, 41-82 years). We also recruited 39 age and gender-matched healthy control subjects. Venous blood samples were taken; serum HGF and CK18 concentrations were determined via ELISA. Results indicated that serum HGF levels were higher in patients (1.37 +/- 0.63 ng/mL) as compared to the healthy subjects (0.41 +/- 0.29 ng/mL). Similarly, serum CK18 levels were higher in the patient group (2.53 +/- 1.33 ng/mL) than in the control group (0.34 +/- 0.23 ng/mL) (P < 0.001). In addition, serum HGF and CK18 levels were positively correlated with metastasis stage, tumor stage, and disease stage of esophageal squamous cell carcinoma. To our knowledge, this is the first study to evaluate serum HGF and CK18 levels in patients with esophageal squamous cell carcinoma. The results suggest that serum CK18 and HGF levels may be used as prognostic and disease monitoring biomarkers of esophageal squamous cell carcinoma. PMID- 27706657 TI - Genetic and correlation analysis of oleoresin chemical components in slash pine. AB - This is the first comprehensive study of the genetic analysis of the majority of oleoresin components of slash pine (Pinus elliottii). Pine oleoresin, the resin secreted from the pine tree, is a raw material widely used in industrial products. The objective of this study was to explore the genetic variation and correlation between the major oleoresin components of 50 open pollinated families of slash pine. The individual narrow-sense heritability of the 23 oleoresin components and genetic correlations between them were estimated using the residual maximum likelihood in the flexible mixed modeling program, ASReml-R. A high heritability of 0.424 was observed for beta-pinene. Moderate levels of heritability were estimated for beta-phellandrene, methyl abietate, estragole, 15 hydroxy-dehydroabietic acid, and isopimaric acid methyl ester at 0.303, 0.294, 0.27, 0.258, and 0.2, respectively. The heritabilities for pimaric acid methyl ester, abieta-8, 13-diene-18-oic acid methyl ester, sandaracopimaric acid, methyl ester, and camphene were relatively low and ranged from 0.11 to 0.17. Many negative genetic correlations were observed as unfavorable while the corresponding phenotypic correlations presented no significant relationships or positive phenotypic correlations. However, the heritabilities and genetic correlations showed that single or multiple component selections and improvement, directly or indirectly, were effective. We postulate that genetic parameters estimated in this study will work as a reference in breeding programs of oleoresin components, especially in slash pine. PMID- 27706659 TI - Molecular cloning, overexpression, purification, and sequence analysis of the giant panda (Ailuropoda melanoleuca) ferritin light polypeptide. AB - The complementary DNA (cDNA) of the giant panda (Ailuropoda melanoleuca) ferritin light polypeptide (FTL) gene was successfully cloned using reverse transcription polymerase chain reaction technology. We constructed a recombinant expression vector containing FTL cDNA and overexpressed it in Escherichia coli using pET28a plasmids. The expressed protein was then purified by nickel chelate affinity chromatography. The cloned cDNA fragment was 580 bp long and contained an open reading frame of 525 bp. The deduced protein sequence was composed of 175 amino acids and had an estimated molecular weight of 19.90 kDa, with an isoelectric point of 5.53. Topology prediction revealed one N-glycosylation site, two casein kinase II phosphorylation sites, one N-myristoylation site, two protein kinase C phosphorylation sites, and one cell attachment sequence. Alignment indicated that the nucleotide and deduced amino acid sequences are highly conserved across several mammals, including Homo sapiens, Cavia porcellus, Equus caballus, and Felis catus, among others. The FTL gene was readily expressed in E. coli, which gave rise to the accumulation of a polypeptide of the expected size (25.50 kDa, including an N-terminal polyhistidine tag). PMID- 27706658 TI - Study on quality standards for Chimonanthus nitens. AB - Chimonanthus nitens Oliv. is a commonly used traditional Chinese medicine. Terpenoids, flavonoids, and coumarins are usually considered its main bioactive ingredients. Thus, qualitative and quantitative analyses of these compounds are crucial in quality control studies of Chimonanthus nitens. In this study, five compounds were identified by double-development thin layer chromatography (TLC) and the content of four compounds was determined by high performance liquid chromatography; the detection wavelength was set to 344 nm and the column temperature was 40 degrees C. All calibration curves showed good linear regression (R2 > 0.9995). The average recoveries ranged from 97.06 to 104.44%. The RSD was below 4.2%. Four compounds remained stable over 24 h and the relative standard deviation (RSD) of the precision of their measurement was less than 1.5%. The developed method was reproducible, sensitive, and simple, and could be used for quality control of Chimonanthus nitens. PMID- 27706660 TI - Preliminary study on total protein extraction methods from Enterococcus faecalis biofilm. AB - Enterococcus faecalis is the major pathogen of post-endodontic disease and refractory periapical periodontitis, and recent research on this species has focused on its pathogenicity. E. faecalis most often causes disease in the form of a biofilm, and total protein expression shows a strong association with its virulence. Therefore, the purpose of our study was to explore different methods of extracting the total proteins of the E. faecalis (ATCC 33186 standard strain) biofilm. The total proteins in the biofilm were extracted using an ultrasonication method with varied parameters, including duration, amplitude setting, period, and duty cycle. After the optimal conditions of ultrasonication were determined based on the protein profile from sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis, the total protein content in the biofilm was detected using the bicinchoninic acid assay, Bradford Coomassie brilliant blue assay, and Lowry assay, and the results were compared and analyzed. The parameters for the optimal conditions of ultrasonication were as follows: a processing duration of 2 min, amplitude setting of 20%, and ultrasonication period of 4 s at a 50% duty cycle. The total protein content was 2299.1 mg/dish when measured by the bicinchoninic assay, 3793.8 mg/dish when measured by the Bradford Coomassie brilliant blue assay, and 1858.0 mg/dish when measured by the Lowry assay. These results demonstrate that the Bradford Coomassie brilliant blue assay is a simple and feasible method for use in detecting the total protein content in a bacterial biofilm. PMID- 27706661 TI - Locally linear embedding and neighborhood rough set-based gene selection for gene expression data classification. AB - Cancer subtype recognition and feature selection are important problems in the diagnosis and treatment of tumors. Here, we propose a novel gene selection approach applied to gene expression data classification. First, two classical feature reduction methods including locally linear embedding (LLE) and rough set (RS) are summarized. The advantages and disadvantages of these algorithms were analyzed and an optimized model for tumor gene selection was developed based on LLE and neighborhood RS (NRS). Bhattacharyya distance was introduced to delete irrelevant genes, pair-wise redundant analysis was performed to remove strongly correlated genes, and the wavelet soft threshold was determined to eliminate noise in the gene datasets. Next, prior optimized search processing was carried out. A new approach combining dimension reduction of LLE and feature reduction of NRS (LLE-NRS) was developed for selecting gene subsets, and then an open source software Weka was applied to distinguish different tumor types and verify the cross-validation classification accuracy of our proposed method. The experimental results demonstrated that the classification performance of the proposed LLE-NRS for selecting gene subset outperforms those of other related models in terms of accuracy, and our proposed approach is feasible and effective in the field of high-dimensional tumor classification. PMID- 27706662 TI - Dynamics of morphological evolution in experimental Escherichia coli populations. AB - Here, we applied a two-stage clonal expansion model of morphological (cell-size) evolution to a long-term evolution experiment with Escherichia coli. Using this model, we derived the incidence function of the appearance of cell-size stability, the waiting time until this morphological stability, and the conditional and unconditional probabilities of morphological stability. After assessing the parameter values, we verified that the calculated waiting time was consistent with the experimental results, demonstrating the effectiveness of the two-stage model. According to the relative contributions of parameters to the incidence function and the waiting time, cell-size evolution is largely determined by the promotion rate, i.e., the clonal expansion rate of selectively advantageous organisms. This rate plays a prominent role in the evolution of cell size in experimental populations, whereas all other evolutionary forces were found to be less influential. PMID- 27706663 TI - Building the SeqChromMM Markov property atlas of the human genome by analyzing the 200-bp units of the 15 different chromatin regions of ENCODE. AB - We analyzed the publicly available ChromHMM BED files of the ENCODE project and tested the Markov properties of the different chromatin states in the human genome. Nucleotide frequency profiles of regional chromatin segmentations were analyzed, and Markov chains were built to detect Markov properties in the chromatin states of different ChromHMM regions. By estimating the transition probabilities of 200-base pair nucleotide sequences of the human genome, we constructed a nucleotide-sequence-based Markovian chromatin map called SeqChromMM. PMID- 27706664 TI - Nanofibers promote HepG2 aggregate formation and cellular function. AB - Formation of hepatocyte spheroids is a necessary strategy for increasing liver specific function in vitro. In this study, HepG2 cells showed good viability when grown on a polylactic acid-chitosan (PLA-CS) nanofiber and aggregated to form multicellular spheroids on the PLA-CS nanofibers with a diameter of approximately 100-200 mm in 5 days of culture, whereas no such aggregation was observed in cells cultured on 24-well plates. Hepatocyte spheroids formed on the PLA-CS nanofibers displayed excellent hepatic-related protein expression, such as albumin and urea, compared to HepG2 cells cultured on the 24-well plates. These results indicated that formation of the hepatocyte spheroids in nanofibers can increase and maintain hepatocyte functions for a longer time, supporting a new strategy for bioartificial liver development. PMID- 27706665 TI - Roles of ERalpha and ERbeta in estrogen-induced DDP chemoresistance in non-small cell lung cancer. AB - The role of estrogen in inducing chemoresistance is not yet fully understood. The objective of this study was to observe the relationship between estrogen levels and cellular response to chemotherapeutic drugs in non-small cell lung cancer (NSCLC) and to reveal the potential mechanisms involved. Cell viability was analyzed after pre-treating NSCLC cells with different levels of estrogen (E2), followed by treatment with an anti-tumor drug for 48 h. The roles of various estrogen receptors (ERs) were examined in vitro by blocking the activity of each ER individually. The ER pathway was further confirmed in NSCLC tissues. It was found that 10-1000 nM E2 resulted in a decreased cellular response to DDP in H1650 cells compared to the use of cisplatin alone (P < 0.05). However, this result was not demonstrated in H1299 cells, which lack p53. Both ERa and ERb were associated with E2-induced cisplatin chemoresistance, though they had opposite functions. p53 expression did not correlate with the expression of ERa or ERb individually. However, a statistically significant correlation between p53 expression and ERa to ERb mRNA ratio was observed (P < 0.001, R = -0.676). These findings suggest that E2-induced DDP chemoresistance depends on the balance between ERa and ERb expression and the p53 pathway. PMID- 27706666 TI - Anti-nociceptive effects of Paecilomyces hepiali via multiple pathways in mouse models. AB - Paecilomyces hepiali (PH), a well-known medicinal fungus, has various pharmacological efficacies. In our study, the antinociceptive effects of PH and underlying mechanisms were evaluated using various mouse models. An acetic acid induced writhing test, hot plate test, and formalin test were employed to evaluate the antinociceptive activities of PH. The levels of neuronal nitric oxide synthase (nNOS) in the hypothalamus and monoamine neurotransmitters in the serum and hypothalamus of experimental mice were examined. Additionally, hot plate tests using mice pretreated with various antagonists were used to determine the mechanisms of PH-mediated antinociception. The PH-enhanced latency period of mice in the hot plate test was significantly blocked by pretreatment with atropine and glibenclamide. PH shortened the phase I and phase II reaction times of formalin-treated mice. Strongly reduced writhing and stretching induced by acetic acid were observed in PH-treated mice, indicating that PH mainly exerts antinociceptive activity on neurogenic pain. After thermal pain stimulation for 30 s, compared to control mice, 7-day PH-treated mice had lower nNOS and dopamine levels, and increased levels of serotonin in both the serum and hypothalamus. Collectively, our data showed that PH mediated antinociceptive activities via multiple pathways, including monoamines, nNOS/ATP-sensitive K+ channels, and M type acetylcholine receptors. PMID- 27706667 TI - Expression and distribution of SP and its NK1 receptor in the brain-gut axis in neonatal maternally separated rat model with visceral hypersensitivity. AB - Neurokinin-1 receptor (NK1R) is a high affinity Substance P (SP) receptor and plays a key role in visceral hypersensitivity in irritable bowel syndrome (IBS). Early life stress is a significant risk factor in IBS. The aim of the present study was to investigate the influence of neonatal maternal separation on the expression and distribution of SP and its receptor along the brain-gut axis in a neonatal maternally separated rat model with visceral hypersensitivity. Male neonatal Sprague-Dawley rats, 2-21-day old, were randomly distributed into maternal separation groups of 3 h daily maternal separation (MS) or non-handling (NH). These rats underwent colorectal balloon distention (CRD) upon reaching adulthood. Immunofluorescence was used to examine the distal colon, lumbosacral spinal cord, and the brainstem to semi-quantitatively determine SP and NK1R expression before and after CRD. The following features were assessed: percentage SP-positive area in colonic muscle layer, the number of NK1R-positive myenteric plexus, SP-positive area and NK1-positivity score in the dorsal horn and the brainstem. Neither of these was altered in the MS and NH groups before or after CRD. These results suggest that the SP system might play little role in the development of visceral hyperalgesia in the neonatal maternal separation rat model. PMID- 27706669 TI - Gene regulatory network identification from the yeast cell cycle based on a neuro fuzzy system. AB - Many studies exist for reconstructing gene regulatory networks (GRNs). In this paper, we propose a method based on an advanced neuro-fuzzy system, for gene regulatory network reconstruction from microarray time-series data. This approach uses a neural network with a weighted fuzzy function to model the relationships between genes. Fuzzy rules, which determine the regulators of genes, are very simplified through this method. Additionally, a regulator selection procedure is proposed, which extracts the exact dynamic relationship between genes, using the information obtained from the weighted fuzzy function. Time-series related features are extracted from the original data to employ the characteristics of temporal data that are useful for accurate GRN reconstruction. The microarray dataset of the yeast cell cycle was used for our study. We measured the mean squared prediction error for the efficiency of the proposed approach and evaluated the accuracy in terms of precision, sensitivity, and F-score. The proposed method outperformed the other existing approaches.

AB - To determine the cytotoxic effect of lymphocytes activated by melanoma-associated antigen 3 (MAGE-3)-sensitized dendritic cells (DCs) on BIU-87 tumor cells, and to evaluate the possibility of MAGE-3-peptide-pulsed DCs as a vaccine in bladder cancer immunotherapy, the proliferation of T cells and the activity of cytotoxic T lymphocytes (CTLs) were examined by the MTT method. CTLs were induced by MAGE-3 sensitized DCs, or by ovalbumin (OVA) peptide and non-sensitized DCs as controls, respectively. The results indicated that MAGE-3-sensitized DCs have the ability to promote the proliferation of T cells as well as the cytotoxic activity of CTLs on bladder cancer cells in comparison with OVA peptide and non-sensitized DCs. In other words, DCs sensitized by the MAGE-3 antigen peptide could obviously upregulate the proliferation of T cells, which resulted in the growth inhibition of bladder cancer BIU-87 cells. In addition, MAGE-3-sensitized DCs played an important role in inhibiting the growth of human BIU-87 tumor xenografts in nude mice. PMID- 27706670 TI - Using Markov chains of nucleotide sequences as a possible precursor to predict functional roles of human genome: a case study on inactive chromatin regions. AB - Recent advances in computational epigenetics have provided new opportunities to evaluate n-gram probabilistic language models. In this paper, we describe a systematic genome-wide approach for predicting functional roles in inactive chromatin regions by using a sequence-based Markovian chromatin map of the human genome. We demonstrate that Markov chains of sequences can be used as a precursor to predict functional roles in heterochromatin regions and provide an example comparing two publicly available chromatin annotations of large-scale epigenomics projects: ENCODE project consortium and Roadmap Epigenomics consortium.

AB - Silica (SiO2) nanoparticles are being progressively applied in various applications, including cosmetics, food technology, and medical diagnostics. Although crystalline SiO2 is a known carcinogen, the carcinogenicity of SiO2 nanoparticles remains unclear. Here, we assessed the cytotoxic effects and DNA injury induced by exposure to various dosages of SiO2 nanoparticles at 0-2400 mg/mL (0-3200 mg/mL microscale SiO2 as positive control) for 24 h using RAW264.7 cells, followed by methyl tetrazolium (MTT) assay. Cells were also treated by 31.25, 125, and 500 mg/mL SiO2 nanoparticles (500 mg/mL microscale SiO2 as positive control) for 24 h and examined by single cell gel electrophoresis assay (SCEG) and flow cytometry. Outstanding dose-related decline in cell viability was observed with enhancing dosages of SiO2 nanoparticles by MTT assay. The inhibitory concentration 50% of SiO2 nanoparticles and microscale SiO2 was 16690 and 5080 mg/mL, respectively. The comet rate (comet%), length of tail, the percentage in DNA tail (TDNA%) and olive tail moment (OTM) induced by SiO2 nanoparticles were significantly increased in comparison with control and microscale SiO2 at 500 mg/mL. 500 mg/mL SiO2 nanoparticles and microscale SiO2 caused a significant increase in apoptosis rate, decreased proliferation index and increased cell proportions in G0/G1 phases by contrast to the negative control (P < 0.05). This indicates that SiO2 nanoparticles are more cytotoxic than microscale SiO2 particles; they induce DNA injury, increase apoptosis, and decrease the proliferation index in RAW264.7 cells. DNA injury and apoptosis may be involved in reducing cell proliferation. PMID- 27706672 TI - Evaluation of four protein extraction methods for proteomic analysis of mango peel. AB - The peel of mango (Mangifera indica L.) is a special plant tissue that contains many compounds that interfere with protein extraction. A successful separation with Two-dimensional electrophoresis (2-DE) is the key step for proteomic analysis. To evaluate the efficiencies of mango peel protein extraction for 2-DE, four extraction methods were tested: 1) 2-D clean-up kit, 2) trichloroacetic acid/acetone precipitation, 3) phenol extraction, 4) phenol with methanol/ammonium acetate precipitation. The results showed that the phenol with methanol/ammonium acetate precipitation produced the best quality protein extraction and separation. Proteins were separated in 30-70 and >70 kDa ranges better than with the other methods. Acidic proteins had better resolution with fewer horizontal and vertical streaks. Sixteen proteins were identified by maxtrix-assisted laser desorption/ ionisation time-of-flight tandem mass spectrometry (MALDI-TOF/ TOF-MS/MS). The result demonstrated that each of these four methods can be used to prepare mango peel proteins. The phenol with methanol/ ammonium acetate precipitation was the best choice for proteomic analysis of mango peel. PMID- 27706673 TI - Novel single nucleotide polymorphisms in the 5' regulatory region of the duck SCD1 gene and their associations with serum biochemical levels and fatty acid composition. AB - Stearoyl-coenzyme A desaturase 1 (SCD1) is the key limiting enzyme in the synthesis of monounsaturated fatty acids, and plays a crucial role in the regulation of oleic acid. In this study, 165 ten-week-old Cherry Valley ducks were used to investigate single nucleotide polymorphisms (SNPs) in the 5' regulatory region of the SCD1 gene, and their associations with duck serum biochemical levels and fatty acid composition. Two novel SNPs, g.936516 C > G and g.936551 T > C, were found by polymerase chain reaction-single-strand conformation polymorphism analysis and DNA sequencing methods, exhibiting six genotypes (AA, BB, CC, AB, AC, and BC). The frequency of the dominant genotype BB and allele B was 0.321 and 0.403, respectively. The polymorphism information content value was 0.617, indicating high polymorphism. The chi-square test indicated that the genotype distribution deviated markedly from Hardy-Weinberg equilibrium (P < 0.01). The linkage of the two mutant sites in the duck SCD1 gene had significant effects on the serum albumin, total protein, globulin, triglyceride, total cholesterol, and cholinesterase levels, as well as on 16 kinds of fatty acids except for C14:1 and C20:0 (P < 0.05). These results indicated that the C allele might have a positive effect on polyunsaturated fatty acids with potential health benefits. Therefore, the SCD1-gene-specific SNPs in the 5' regulatory region may be a useful marker for serum lipid, serum protein, and fatty acid composition in future marker-assisted selection for duck breeding. PMID- 27706674 TI - Immunological impression cytology of the conjunctival epithelium in patients with thyroid orbitopathy-related dry eye. AB - Thyroid orbitopathy (TO) is an autoimmune disease that is complicated by ocular surface disorders, leading to discomfort. Dry eye is very prevalent in patients with TO. Recent studies on the pathogenesis of dry eye have focused on the inflammatory process, and some supporting evidence has been discovered. Because TO is a disorder of autoimmune origin, we assumed that the association between TO and dry eye is related to inflammation. Inflammation of the ocular surface in TO related dry eye has not been well studied. In this study, we assessed cellular inflammation of the ocular surface and the cytokine profiles in patients with TO related dry eye. Conjunctival impression cytology (CIC) was assessed with an immunofluorescent assay. TO-related dry eye was diagnosed by using the Schirmer test, tear break-up time, thyroid function, and clinical signs. CIC was combined with immunological staining of interleukin-1a (IL-1a), IL-1b, and IL- 6. The immunological impression cytology (IC) grade was compared to the clinical activity score of TO. All TO patients with dry eye were positive for IL-1a, IL 1b, and IL-6. However, the normal controls were also positive for IL-1a. A trend was observed between the clinical inflammatory score and immunological IC grade. This study was the first to delineate the immunological IC of TO-related dry eye. Our study aimed to investigate the pathogenesis of dry eye in TO. Our findings suggest that the conjunctival cytokines IL-1a, IL-1b, and IL-6 may play a role. The results of this study will be useful for future studies of additional inflammatory cytokines, and the levels of these cytokines could be used as an outcome to assess the efficacy of treatment, such as anti-cytokine or immunosuppression therapy, in patients with TO-related dry eye or other ocular surface inflammatory disorders. PMID- 27706675 TI - Letter to the Editor "Drosha, DGCR8, and Dicer mRNAs are downregulated in human cells infected with dengue virus 4" - Genet. Mol. Res. 15 (2): gmr.15027891 - Drosha, Dicer, and TRBP mRNA are downregulated in Vero cells with the 3'UTR of Dengue virus. AB - Dear Editor, A recent paper (Casseb et al., 2016) published in the journal Genetics and Molecular Research described the interesting concept that dengue virus (DENV)-4 infection, in the human cell line A-549, leads to the downregulation of expression of key components of microRNA (miRNA) biogenesis, such as Drosha, Dicer, and DGCR8. For this, the authors performed a time course infection of A-549 cells for 5 days. The highest viral load was observed at 3 days post-infection, which corresponded with the maximum downregulation of expression of Drosha, Dicer, and DGCR8, assayed by quantitative PCR (RT-qPCR). These results supported the recent notion of a complex interaction between DENV and the host miRNA machinery and of the host miRNA response to this particular infection. Extensive evidence has shown that DENV can take advantage of host miRNAs for its own replication (Zhu et al., 2014) and that host miRNAs can inhibit DENV replication (Wu et al., 2013). PMID- 27706676 TI - Effect of compound Maqin decoction on TGF-beta1/Smad proteins and IL-10 and IL-17 content in lung tissue of asthmatic rats. AB - In this research, compound Maqin decoction (CMD) has been shown to positively affect in airway inflammation of asthma models. We evaluated the effects of CMD on the expression of transforming growth factor (TGF)-beta1/Smad proteins, interleukin (IL)-17, and IL-10 in lung tissue of asthmatic rats. Asthma was induced in a rat model using ovalbumin. After a 4-week treatment with CMD, rats were killed to evaluate the expression of TGF-beta1 and Smad proteins in lung tissue. IL-10 and IL-17 levels in lung tissue homogenates were determined by ELISA. The expression of TGF-beta1 and Smad3 protein increased, whereas expression of Smad7 protein decreased upon high-dose or low-dose treatment with CMD or by intervention with dexamethasone, compared to the control. There was a significant difference between treatment with a high dose CMD and the control treatment, but no significant difference was found between high-dose CMD treatment and dexamethasone intervention. The expression of TGF-beta1 and Smad7 protein increased, whereas the expression of Smad3 protein decreased in the model group compared to other groups. In the CMD high-dose group, low-dose group, and dexamethasone intervention group, the IL-17 concentrations in lung tissue homogenates were decreased, while IL-10 levels were increased. Again, there was a significant difference between CMD high-dose and control treatment, but not between CMD high-dose treatment and dexamethasone intervention. Thus, positive effects of CMD against asthmatic airway remodeling may be due to its regulatory effect on TGF-beta1, Smad3, and Smad7 protein levels and on cytokines such as IL 10 and IL-17. PMID- 27706677 TI - Effect of miR-29c and miR-129-5p on epithelial-mesenchymal transition in experimental biliary atresia mouse models. AB - Biliary atresia (BA) is a destructive bile duct disease occurring in newborn children within a few weeks after birth. In this study, the effect of miR-29c and miR-129-5p on epithelial-mesenchymal transition (EMT) in experimental BA was explored by constructing BA mouse models via Rhesus rotavirus vaccine infection. miR-29c and miR-129-5p expression was analyzed by real-time quantitative polymerase chain reaction. EMT was established by induction with transforming growth factor (TGF)-beta1. miR-29c and miR-129-5p were overexpressed and inhibited, respectively, by Lipofectamine transfection. EMT-related protein (formin-like 2, FMNL2; E-cadherin; vimentin; and cytokeratin-19, CK-19) expression was analyzed by western blot and immunofluorescent assay. The results indicated that miR-29c and miR-129-5p were downregulated and upregulated in BA mice. TGF-beta1 induction caused a time-dependent decrease and increase in miR 29c and miR-129-5p, respectively. Additionally, TGF-beta1 induced an increase in FMNL2 and vimentin expression and a decrease in E-cadherin and CK-19 expression (P < 0.05). Overexpression or suppression of miRNA-29c or miR-129-5p, respectively, induced the inhibition of FMNL2 and vimentin, and promotion of E cadherin and CK-19 expression, in the test groups compared to the non intervention group (P < 0.05). However, the FMNL2, vimentin, E-cadherin, and CK- 19 expression did not differ between the control and non-intervention groups (P > 0.05). Thus, miR-29c upregulation or miR-129-5p downregulation effectively prevented EMT in BA by regulating the expression of EMT pathway-related proteins. Therefore, miR-29c and miR-129-5p could be utilized as therapeutic targets for BA in the future. PMID- 27706678 TI - Tim-3 facilitates osteosarcoma proliferation and metastasis through the NF-kappaB pathway and epithelial-mesenchymal transition. AB - The aim of this study was to investigate the expression of T-cell immunoglobulin mucin domain molecule-3 (Tim-3) in osteosarcoma tissues, and analyze its effect on cell proliferation and metastasis in an osteosarcoma cell line. Tim-3 mRNA and protein expression in osteosarcoma tissue was detected by reverse transcriptase polymerase chain reaction and immunohistochemistry, respectively. Additionally, the cell viability, apoptosis rate, and invasive ability of the osteosarcoma cell line MG-63 were tested using the methyl thiazolyl tetrazolium assay, Annexin V propidium iodide flow cytometry, and a Transwell assay, respectively, following Tim-3 interference using small interfering RNA (siRNA). We also analyzed the expression of Snail, E-cadherin, vimentin, and nuclear factor (NF)-kB in the cells by western blot. We observed that Tim-3 mRNA and protein was significantly overexpressed in osteosarcoma tissues, compared to the adjacent normal tissue (P < 0.01). Moreover, MG-63 cells transfected with the Tim-3 siRNA presented lower cell viability, a greater number of apoptotic cells, and decreased invasive ability (P < 0.01), compared to control cells. Additionally, we observed a decrease in Snail and vimentin expression, an increase in the E-cadherin level, and an increase in NF-kB p65 phosphorylation (P < 0.01) in Tim-3 siRNA transfected MG-63 cells. Based on these results, we concluded that Tim-3 is highly expressed in osteosarcoma tissue. Moreover, we speculated that interfering in Tim-3 expression could significantly suppress osteosarcoma cell (MG-63) proliferation and metastasis via the NF-kB/Snail signaling pathway and epithelial mesenchymal transition. PMID- 27706679 TI - Association of single-nucleotide polymorphisms, rs2235371 and rs2013162, in the IRF6 gene with non-syndromic cleft palate in northeast China. AB - The aim of this study was to determine the association between two SNPs (rs2235371 and rs2013162) in the interferon regulatory factor 6 (IRF6) gene and non-syndromic cleft palate (NSCP) in northeast China. We genotyped these two SNPs in 104 NSCP cases, as well as in 178 parents and 300 controls. Case-control and case-parent analyses were performed using chi2 tests and family-based association tests (FBAT). Results indicated that there were significant differences in both genotypic and allelic distributions between patients and controls at rs2235371 and rs2013162 in the IRF6 gene. Case-parent analysis revealed over-transmission of the C allele in rs2235371 and the A allele in rs2013162. Lastly, FBAT showed over-transmission of the CA haplotype. This study demonstrated that the two SNPs, rs2235371 and rs2013162, are strongly associated with NSCP in the northeast Chinese population. PMID- 27706680 TI - Association between TXNRD1 polymorphisms and anti-tuberculosis drug-induced hepatotoxicity in a prospective study. AB - Anti-tuberculosis drug-induced hepatotoxicity (ATDH) is a serious adverse reaction to anti-tuberculosis (TB) treatment. Thioredoxin reductase 1 (TXNRD1), encoded by the TXNRD1 gene, is an important enzyme involved in oxidant challenge. TXNRD1 plays a key role in regulating cell growth and transformation, and protects cells against oxidative damage. We investigated the association between TXNRD1 polymorphisms and ATDH susceptibility. In this prospective study, 280 newly diagnosed TB patients were followed-up for 3 months after beginning anti-TB therapy. Tag single-nucleotide polymorphisms (tag-SNPs) of TXNRD1 were selected using Haploview 4.2 based on the HapMap database of the Chinese Han in Beijing (CHB) panel. Genotyping was performed using the MassARRAY platform. Of the 280 patients enrolled in this study, 33 were lost to follow-up, 24 had ATDH, and 223 were free from ATDH. After adjusting for sex, age, smoking status, and body mass index, there were no significant differences in the allele and genotype frequency distributions of TXNRD1 SNPs between the ATDH and non-ATDH groups (all P > 0.05). The haplotype analysis showed that haplotype TCAGCC was associated with an increased risk of ATDH susceptibility [P = 0.024, OR (95%CI) = 6.273 (1.023 38.485)]. Further stratified analyses showed that the haplotype TCAGCC was associated with ATDH susceptibility in female subjects [P = 0.036, OR (95%CI) = 5.711 (0.917-35.560)] and non-smokers [P = 0.029, OR (95%CI) = 6.008 (0.971 37.158)]. Our results suggest that TXNRD1 variants may favor ATDH susceptibility in females and non-smokers. Further studies are required to verify this association. PMID- 27706681 TI - Reversal of cisplatin resistance in non-small cell lung cancer stem cells by Taxus chinensis var. AB - Drug resistance in cells is a major impedance to successful treatment of lung cancer. Taxus chinensis var. inhibits the growth of tumor cells and promotes the synthesis of interleukins 1 and 2 and tumor necrosis factor, enhancing immune function. In this study, T. chinensis var.-induced cell death was analyzed in lung cancer cells (H460) enriched for stem cell growth in a defined serum-free medium. Taxus-treated stem cells were also analyzed for Rhodamine 123 (Rh-123) expression by flow cytometry, and used as a standard functional indicator of MDR. The molecular basis of T. chinensis var.-mediated drug resistance was established by real-time PCR analysis of ABCC1, ABCB1, and lung resistance-related protein (LRP) mRNA, and western blot analysis of MRP1, MDR1, and LRP. Our results revealed that stem cells treated with higher doses of T. chinensis var. showed significantly lower growth inhibition rates than did H460 cells (P < 0.05). The growth of stem and H460 cells treated with a combination of T. chinensis var. and cisplatin was also significantly inhibited (P < 0.05). Rh-123 was significantly accumulated in the intracellular region and showed delayed efflux in stem cells treated with T. chinensis var. (P < 0.05), compared to those treated with verapamil. T. chinensis var.-treated stem cells showed significant downregulation of the ABCC1, ABCB1, and LRP mRNA and MRP1, MDR1, and LRP (P < 0.05) compared to H460 cells. Thus, T. chinensis var.-mediated downregulation of MRP1, MDR1, and LRP might contribute to the reversal of drug resistance in non-small cell lung cancer stem cells. PMID- 27706682 TI - Effects of ginsenoside Rg1 on the senescence of vascular smooth muscle cells. AB - The development of age-related cardiovascular disease is associated with the senescence of vascular cells. This study aimed to investigate the effect of ginsenoside Rg1 on vascular smooth muscle cell (VSMC) senescence. Primary VSMCs were cultured and divided into control, D-galactose (D-gal), Rg1-L, and Rg1-H groups, which were cultured without and with D-gal, and with low- and high concentrations of Rg1, respectively. D-gal-induced cellular senescence was identified by b-galactosidase staining, and ultrastructural changes within the cells were observed. The expression of p16, p21, and p53 in the four groups of VSMCs was determined by western blotting, and the cell cycle was investigated by flow cytometry. Compared with the control group, there was an obvious change in the ultrastructure of VSMCs in the D-gal group, and the proportion of b galactosidase-positive cells was significantly increased (P < 0.05). In addition, p16, p21, and p53 expression was significantly increased (P < 0.05) and the cell cycle was arrested in the G0/G1 phase. Compared with the D-gal group, the percentage of positive cells was significantly reduced (P < 0.05) in the Rg1 groups, the expression of p16, p21, and p53 was significantly reduced (P < 0.05), and the number of cells in the G0/G1 phase decreased (P < 0.05). Ginsenoside Rg1 can inhibit VSMC senescence, and the mechanisms may be related to its partial inhibition of the p16INK4a/Rb and p53-p21Cip1/Waf1 signaling pathways during the cell cycle. PMID- 27706683 TI - Association of polymorphisms in growth hormone and leptin candidate genes with live weight traits of Brahman cattle. AB - Polymorphisms in candidate genes can produce significant and favorable changes in the phenotype, and therefore are useful for the identification of the best combination of favorable variants for marker-assisted selection. In the present study, an assessment to evaluate the effect of 11 single nucleotide polymorphisms (SNPs) in candidate genes on live weight traits of registered Brahman cattle was performed. Data from purebred bulls were used in this assessment. The dataset included birth (BW), weaning (WW), and yearling (YW) weights. A panel of 11 SNP markers, selected by their formerly reported or apparent direct and indirect association with live weight traits, was included in an assessment previously confirming their minimum allele frequency (<0.05). Live weights were adjusted BW (aBW), WW (aWW), and YW (aYW) using a generalized linear model, which included the fixed effects of herd and season of birth and the random effect of the sire and year of birth. An SNP in a growth hormone gene (GH4.1) was significantly related to aWW (P = 0.035) with an estimate substitution effect of 3.97 kg (P = 0.0210). In addition, a leptin SNP (LEPg.978) was significantly associated with aYW (P = 0.003) with an estimate substitution effect of 9.57 kg (P = 0.0007). The results suggest that markers GH4.1 and LEPg.978 can be considered as candidate loci for assisted genetic improvement programs in Mexican Brahman cattle. PMID- 27706685 TI - Polymorphic microsatellite markers for the endangered fish, the slender shiner Pseudopungtungia tenuicorpa and cross-species amplification across five related species. AB - The slender shiner Pseudopungtungia tenuicorpa (Cypriniformes; Cyprinidae; Gobioninae) is an endangered freshwater fish species endemic to Korea. The current strategies for its conservation involve the study of population genetic characters and identification of management units. These strategies require suitable molecular markers to study genetic diversity and genetic structure. Here, we developed nine polymorphic microsatellite markers for P. tenuicorpa for the first time by applying an enrichment method from a size-selected genomic library. The developed microsatellite markers produced a total of 101 alleles (average 11.2). The observed and expected heterozygosities averaged 0.805 and 0.835, respectively. Among the nine identified markers, five markers showed successful amplification across five related Korean Gobioninae species. Thus, the microsatellite markers developed in this study will be useful to establish conservation strategies for both P. tenuicorpa and other related species. PMID- 27706684 TI - Effects of DNA methyltransferase inhibitor RG108 on methylation in buffalo adult fibroblasts and subsequent embryonic development following somatic cell nuclear transfer. AB - Buffalo are characteristic livestock of the Guangxi Zhuang Autonomous Region of China, but their low reproductive capacity necessitates the use of somatic cell nuclear transfer (SCNT). We investigated the effects of RG108 on DNA methylation in buffalo adult fibroblasts, and on subsequent SCNT embryo development. RG108 treatment (0, 5, 10, 20, and 100 mM) had no effect on cell morphology, viability, or karyotype (2n = 48), and cell growth followed a typical "S" curve. Immunohistochemistry showed that relative DNA methylation gradually decreased as RG108 concentration increased, and was significantly lower in the 20 and 100 mM groups compared to the 0, 5, and 10 mM treatments (0.94 +/- 0.03 and 0.92 +/- 0.05 vs 1.0 +/- 0.02, 0.98 +/- 0.05, and 0.98 +/- 0.09, respectively; P < 0.05). Quantitative polymerase chain reaction revealed that DNMT1 gene expression of fibroblasts administered 10, 20, and 100 mM RG108 was significantly lower than those in the 0 and 5 mM groups (0.2 +/- 0.05, 0.18 +/- 0.07, and 0.3 +/- 0.09 vs 1.0 +/- 0.12 and 1.4 +/- 0.12, respectively; P < 0.05). Treatment with 20 mM RG108 resulted in the lowest expression levels. Fibroblasts incubated with 20 mM RG108 for 72 h were used as donor cells to generate SCNT embryos. A greater number of such embryos developed into blastocysts compared to the non-treated group (28.9 +/- 3.9 vs 15.3 +/- 3.4%; P < 0.05). RG108 treatment can modify DNA methylation in buffalo adult fibroblasts and promote development of subsequent SCNT embryos. PMID- 27706686 TI - Identification and characterization of SREBF2 expression and its association with chicken carcass traits. AB - The sterol regulatory element-binding transcription factor 2 gene (SREBF2) plays an important role in regulating lipid homeostasis. To reveal the genetic factors that underlie carcass fat deposition in chickens, we cloned the coding DNA sequence of chicken SREBF2, investigated SREBF2 mRNA expression levels in various tissues, detected single nucleotide polymorphisms (SNPs) in the exon regions of the gene, and conducted association analyses between single markers/haplotypes and carcass traits. The entire 2859-bp cDNA sequence of chicken SREBF2 that encoded 952 amino acids was obtained and characterized. SREBF2 mRNA was highly expressed in the uropygial gland, followed by the liver, breast muscle, and leg muscle. Ten SNPs were detected, and four (g.49363077T>A, g.49357503C>T, g.49355533G>A, and g.49354641G>A) were novel. When analyzing the associations between the single mutations and carcass traits, significant differences were found in three SNPs and g.49357915G>A was highly significantly associated with most carcass traits, except for abdominal fat weight and sebum thickness. In addition, haplotype combinations that were constructed using the SREBF2 SNPs were associated with breast muscle weight. Chickens with the combined genotype H21H21 had the highest live weight, carcass weight, eviscerated weight, and semi eviscerated weight values. To the best of our knowledge, this is the first study conducted on chicken SREBF2 polymorphisms, which are predictive of the genetics that underlie the economic performance of chickens. PMID- 27706687 TI - Antimutagenicity and antigenotoxicity of Aloe arborescens Miller and Aloe barbadensis Miller in Aspergillus nidulans and Wistar rats. AB - Medicinal plants such as Aloe arborescens Miller and Aloe barbadensis Miller are used by the general population to treat various diseases. Therefore, the aim of this study was to evaluate the antimutagenicity of these two species using a methG1 system in Aspergillus nidulans and the comet assay in rats. The animals were treated with the plants at concentrations of 360 and 720 mg/kg body weight (1 and 2, respectively) by gavage for 14 days, followed by the administration of etoposide on treatment day 8. Blood samples were prepared for analysis of DNA damage. For the test in A. nidulans, the biA1methG1 lineage conidia were treated for 4 h with both plant species at concentrations of 4 and 8% (w/v). Then, they were washed and plated on a selective medium for frequency analysis of survival and mutation. The results of the comet assay showed that both plants were antigenotoxic compared to etoposide, which was not a typical response of methG1 systems, where only the highest concentration of plant extracts usually exhibit beneficial effects. This study demonstrates the potential antigenotoxicity and antimutagenicity of the Aloe plants tested and, therefore, supports their use as a form of preventive therapy and for health maintenance by the population. PMID- 27706688 TI - Role of ABCB1 C1236T, G2677T, and C3435T genetic polymorphisms in the development of acute leukemia in a Chinese population. AB - We carried out a case-control study to examine the relationship between the ATP binding cassette subfamily B member 1 (ABCB1) gene polymorphisms C1236T, G2677T, and C3435T and risk of acute leukemia in a Chinese population. Between May 2013 and April 2015, we recruited 164 acute leukemia patients and 285 healthy controls, and determined polymorphism genotypes by polymerase chain reaction restriction fragment length polymorphism. Using unconditional logistic regression analysis, we observed that in comparison to the wild-type sequence, the TT genotype [odds ratio (OR) = 2.15, 95% confidence interval (CI) = 1.12-4.10; P = 0.01] and the T allele (OR = 1.39, 95%CI = 1.05-1.86; P = 0.02) of ABCB1 G2677T were associated with acute leukemia susceptibility. The TT genotype (OR = 2.03, 95%CI = 1.11- 3.69; P = 0.01) and the T allele (OR = 1.39, 95%CI = 1.05-1.85; P = 0.02) of the C3435T polymorphism also increased acute leukemia risk compared to the wild-type form. However, no significant relationship was established between the ABCB1 C1236T variant and this disease. Our results suggest that the ABCB1 G2677T and C3435T sequence variations may affect susceptibility to acute leukemia. PMID- 27706689 TI - Comparative analysis of soybean genotype resistance to Heterodera glycines and Meloidogyne species via resistance gene analogs. AB - Nematodes are important pests of soybean throughout the world and cause high yield losses. As a control strategy, the identification of resistance genes is an important aim of breeding studies. Plants possess resistance genes (R), which are responsible for the recognition of pathogens and activation of the defense system. R genes and resistance gene analogs (RGAs) possess conserved domains, from which nucleotide-binding site is the most common. Using degenerate primers originating from these domains, it is possible to identify and isolate sequences of R and RGA genes. In this study, soybean genotypes resistant to the nematodes Heterodera glycines, Meloidogyne incognita, M. javanica, and M. enterolobii were compared by the use of RGAs and simple sequence repeat (SSR) markers. Forty-six soybean genotypes were studied, including plant introductions (PIs), commercial crops, and source of resistance genotypes. Thirteen combinations of RGA primers and different SSRs linked to QTLs were used to confirm resistance to soybean cyst nematodes (SCN). Fragments associated with resistance to the studied nematodes were amplified in the source of resistance and PI genotypes. RGA markers were efficient at distinguishing groups of genotypes that were resistant and susceptible to Meloidogyne spp and SCN. Combinations of specific primers were identified through their ability to amplify nucleotide sequences from possible resistance candidate genes. SSR markers contributed to the analysis of SCN race specificity, showing that the QTLs identified by these markers are distinct from those identified by RGA markers. PMID- 27706690 TI - Effects of intra-articular injection of mesenchymal stem cells associated with platelet-rich plasma in a rabbit model of osteoarthritis. AB - The current study aims to evaluate the macroscopic and histological effects of autologous mesenchymal stem cells (MSC) and platelet-rich plasma on knee articular cartilage regeneration in an experimental model of osteoarthritis. Twenty-four rabbits were randomly divided into four groups: control group, platelet-rich plasma group, autologous MSC undifferentiated group, and autologous MSC differentiated into chondrocyte group. Collagenase solution was used to induce osteoarthritis, and treatments were applied to each group at 6 weeks following osteoarthritis induction. After 60 days of therapy, the animals were euthanized and the articular surfaces were subjected to macroscopic and histological evaluations. The adipogenic, chondrogenic, and osteogenic differentiation potentials of MSCs were evaluated. Macroscopic and histological examinations revealed improved tissue repair in the MSC-treated groups. However, no difference was found between MSC-differentiated and undifferentiated chondrocytes. We found that MSCs derived from adipose tissue and platelet-rich plasma were associated with beneficial effects in articular cartilage regeneration during experimental osteoarthritis. PMID- 27706692 TI - Association of ectomycorrhizal fungi with Picea crassifolia (Pinaceae, Piceoidae) from high-altitude stands in Mount Helan Nature Reserve, China. AB - We investigated the diversity of ectomycorrhiza associated with the endemic Picea crassifolia in Mount Helan National Nature Reserve in Inner Mongolia, China. Toward this objective, we conducted morphological and molecular identification of ectomycorrhizae in soil cubes taken from pure P. crassifolia stands. Eleven types of ectomycorrhizal (ECM) organisms were separated, briefly described, and identified. Nine morphotypes belonged to the phylum Basidiomycotina [Amphinema byssoides, Cortinarius sp (cf. limonius), Cortinarius vernus, Inocybe cf. nitidiscula, Inocybe sp 1, Sebacina incrustans, Sebacina sp, Suillus luteus, and Piceirhiza tuberculata x Picea crassifolia (comb. Nov.)], and two morphotypes to the phylum Ascomycotina (Cenococcum geophilum and Helvella sp). The diversity of ECM organisms in P. crassifolia was lower than that reported by other studies on spruce or pine forests, or on sporocarp diversity in the high-mountain forests of China. Most of the fungi in the rhizosphere did not correspond to species previously recorded as sporocarps above ground. Here, several new ectomycorrhiza morphotypes are proposed and described. We also confirmed the ectomycorrhizal status of the genus Sebacina (order Sebacinales). PMID- 27706691 TI - Discovery of differentially expressed genes in cashmere goat (Capra hircus) hair follicles by RNA sequencing. AB - The mammalian hair follicle (HF) is a unique, highly regenerative organ with a distinct developmental cycle. Cashmere goat (Capra hircus) HFs can be divided into two categories based on structure and development time: primary and secondary follicles. To identify differentially expressed genes (DEGs) in the primary and secondary HFs of cashmere goats, the RNA sequencing of six individuals from Arbas, Inner Mongolia, was performed. A total of 617 DEGs were identified; 297 were upregulated while 320 were downregulated. Gene ontology analysis revealed that the main functions of the upregulated genes were electron transport, respiratory electron transport, mitochondrial electron transport, and gene expression. The downregulated genes were mainly involved in cell autophagy, protein complexes, neutrophil aggregation, and bacterial fungal defense reactions. According to the Kyoto Encyclopedia of Genes and Genomes database, these genes are mainly involved in the metabolism of cysteine and methionine, RNA polymerization, and the MAPK signaling pathway, and were enriched in primary follicles. A microRNA-target network revealed that secondary follicles are involved in several important biological processes, such as the synthesis of keratin-associated proteins and enzymes involved in amino acid biosynthesis. In summary, these findings will increase our understanding of the complex molecular mechanisms of HF development and cycling, and provide a basis for the further study of the genes and functions of HF development. PMID- 27706693 TI - Role of ADH2 and ALDH2 gene polymorphisms in the development of Parkinson's disease in a Chinese population. AB - In this study, we investigated the role of ADH2 Arg47His and ALDH2 Glu487Lys genetic polymorphisms in the development of Parkinson's disease in a Chinese population. Between January 2013 and May 2014, 115 patients with Parkinson's disease and 214 healthy controls were recruited in our study. Genotyping of ADH2 Arg47His and ALDH2 Glu487Lys polymorphisms was performed by the polymerase chain reaction-restriction fragment length polymorphism method. In the dominant model, the GA + AA genotype of ALDH2 Glu487Lys was found to be significantly associated with elevated risk of Parkinson's disease when compared with the GG genotype [odds ratio = 1.71, 95% confidence interval (CI) = 1.02-2.84]. In the recessive model, the AA genotype of ALDH2 Glu487Lys showed a 4.87-fold increase (95%CI = 1.54-18.03) in the risk of Parkinson's disease when compared to the GG and GA genotypes. However, no significant association was found between the ADH2 Arg47His polymorphism and risk of Parkinson's disease in the co-dominant, dominant, or recessive models. In conclusion, our study suggests that the ALDH2 polymorphism could influence the development of Parkinson's disease in the Chinese population studied here. PMID- 27706694 TI - Effect of organic matter enrichment on the fungal community in limestone cave sediments. AB - Caves are considered major touristic attractions. The management plans of many such caves include limiting the number of visitors; however, the human impact on microbial communities within caves is rarely considered. Therefore, the aim of this study was to evaluate the impact of human-transferred organic matter on the fungal microcosms growing on cave sediments. Samples were collected from a Brazilian limestone cave and cultured with 0.25 or 0.5% 1:1 (w/w) beef and yeast extract (simulating organic matter) under laboratory conditions. The contaminated fungal community was then evaluated at days 0, 30, 180, and 365 after inoculation by polymerase chain reaction denaturing gradient gel electrophoresis. We observed changes in the fungal communities with time, as well as the concentration of added organic matter, compared to the control fungal communities. Additionally, the contaminated microcosms showed a greater number of operational taxonomic units compared to the controls. These findings suggest that tourist activity could cause fungal outbreaks of possible human pathogens, demonstrating the importance of fungal monitoring in these caves. PMID- 27706695 TI - Effect of polychlorinated biphenyls on oxidation stress in the liver of juvenile GIFT, Oreochromis niloticus. AB - The present study clearly showed that chronic exposure to polychlorinated biphenyls (PCBs) at environmentally relevant concentrations can damage juvenile tilapia livers by modulating antioxidant enzyme activities and gene transcription, which affects toxic bioaccumulation and histological congestion. The results suggest that PCBs caused a decrease in the activity of some hepatic antioxidative and biotransformation enzymes (SOD, CAT, GST, T-GSH, and MDA) in tilapia at 7 days, as well as transcriptional changes (sod, cat, and gst). Except for some antioxidant parameters (T-GSH, GSH/GSSG, T-AOC, and MDA), significant declines and increases occurred at 14 and 21 days, respectively. Most of the antioxidant enzymatic signatures and genotoxicity significantly increased at 14 and 21 days. This study presented evidence that PCBs could result in hepatic toxicity through oxidative stress in the early growth stages of tilapia, and we speculated that oxidative stress plays an important role in embryonic developmental toxicity induced by PCBs. PMID- 27706696 TI - Genetic diversity in cassava landraces grown on farms in Alta Floresta-MT, Brazil. AB - Brazil is considered one of the domestication centers of cassava (Manihot esculenta), containing a large part of the biological diversity and traditional knowledge of the species. The aim of the present study was to evaluate the genetic diversity of cassava landraces grown by farmers in the north of Mato Grosso State, Brazil, using inter simple sequence repeat (ISSR) molecular markers. The study was carried out in the municipality of Alta Floresta, MT, on farms located in two rural areas. Seventeen cassava landraces were selected. The DNA was extracted and polymerase chain reaction amplifications were performed using 15 ISSR primers. Genetic similarity estimates were calculated using Jaccard's index and the generated matrix was used for clustering the genotypes by using UPGMA and Tocher's methods. The 15 ISSR primers amplified 120 fragments, revealing 61.67% polymorphism. The polymorphism information content ranged from 0.04 to 0.61, averaging 0.39. The most similar genotypes were AF5 and AF8, whereas the least similar were AF1 and AF16. The UPGMA clustering method formed five groups. Group I included twelve landraces, Group II contained two, and the other groups contained one landrace each. Tocher's method resulted in six groups: 12 landraces clustered in one group, and the other groups each contained one landrace. The ISSR markers proved efficient in revealing genetic diversity among the cassava landraces. The landraces grown by farmers in the two rural areas of Alta Floresta have a great variability and, thus, can be exploited in programs for breeding and preservation of the species. PMID- 27706697 TI - Effect of polychlorinated biphenyls on osmoregulatory response and apoptosis in GIFT tilapia, Oreochromis niloticus. AB - In the present study, GIFT tilapia Oreochromis niloticus were exposed to polychlorinated biphenyls (PCBs) for 7, 14, and 21 days. Over the duration of the exposure, genotoxicity and the activity of Na+/K+-ATPase (NKA) and Ca+/Mg+-ATPase (CMA) were measured in the gill, kidney, and intestine, to evaluate changes in osmoregulatory response in O. niloticus. Our results showed significant decreases in organic NKA (except in gill tissues after 0.5 mg/L PCB-exposure) and CMA activity. The results of the genotoxicity assay showed significant increases in atp1a1a, nkcc2 (only in gill tissue), and fxyd7 (except after 21 days of 5 mg/L PCB exposure). We found significant increases in caspase proteins in the liver in the 5-mg/L PCB exposure group, and the transcripts showed dose-dependent increases between treatment groups over the exposure duration. This study presents evidence that chronic exposure to PCB could result in organic osmoregulatory response and hepatic apoptosis in GIFT tilapia. PMID- 27706698 TI - Genetic potential of common bean progenies obtained by different breeding methods evaluated in various environments. AB - Grain yield is strongly influenced by the environment, has polygenic and complex inheritance, and is a key trait in the selection and recommendation of cultivars. Breeding programs should efficiently explore the genetic variability resulting from crosses by selecting the most appropriate method for breeding in segregating populations. The goal of this study was to evaluate and compare the genetic potential of common bean progenies of carioca grain for grain yield, obtained by different breeding methods and evaluated in different environments. Progenies originating from crosses between lines and CNFC 7812 and CNFC 7829 were replanted up to the F7 generation using three breeding methods in segregating populations: population (bulk), bulk within F2 progenies, and single-seed descent (SSD). Fifteen F8 progenies per method, two controls (BRS Estilo and Perola), and the parents were evaluated in a 7 x 7 simple lattice design, with plots of two 4-m rows. The tests were conducted in 10 environments in four States of Brazil and in three growing seasons in 2009 and 2010. Genetic parameters including genetic variance, heritability, variance of interaction, and expected selection gain were estimated. Genetic variability among progenies and the effect of progeny environment interactions were determined for the three methods. The breeding methods differed significantly due to the effects of sampling procedures on the progenies and due to natural selection, which mainly affected the bulk method. The SSD and bulk methods provided populations with better estimates of genetic parameters and more stable progenies that were less affected by interaction with the environment. PMID- 27706699 TI - Increased miR-155-5p expression in dermal mesenchymal stem cells of psoriatic patients: comparing the microRNA expression profile by microarray. AB - Mesenchymal stem cells (MSCs) have pleiotropic immuno-modulatory effects and pro angiogenic ability, leading to the presumption that MSCs may be involved in the pathogenesis of many inflammatory or autoimmune disorders, including psoriasis. In a previous study, we reported the specific gene expression profile of dermal MSCs from psoriasis. Inflammation- and angiogenesis-related genes, such as lipopolysaccharide-induced tumor necrosis factor-alpha transcription factor (LITAF), dual-specificity protein phosphatase 1 (DUSP1), vascular endothelial growth factor alpha (VEGFalpha), and insulin-like growth factor-binding protein-5 (IGFBP5), are abnormally expressed in psoriatic dermal MSCs. As a key regulator of gene expression, miRNA are involved in a wide variety of biological processes; in fact, several miRNAs have been implicated in the development and progression of inflammatory or autoimmune disorders. In this study, we compared the miRNA expression profiles of dermal MSCs from patients with psoriasis to those in MSCs from normal individuals by microarray, and found that the pro-inflammatory miRNA miR-155 was significantly overexpressed in psoriatic MSCs (2.44 fold, P < 0.001). Additionally, the expression of miR-155 target gene TAB2 (8.47 +/- 1.55 vs 6.38 +/- 2.10, P < 0.01,) and the downstream gene iNOS (5.26 +/- 2.58 vs 3.73 +/- 1.89, P < 0.05) was found to be inhibited in psoriatic dermal MSCs by real-time PCR. Therefore, we speculated that the elevation in miR-155 levels may be an indicator of, or a key regulatory pathway in, the pathogenesis of psoriasis, resulting in functionally impaired dermal MSCs. PMID- 27706700 TI - Bioinformatic and expression analysis of the OMT gene family in Pyrus bretschneideri cv. Dangshan Su. AB - With high nutritional value in its fruits, Dangshan Su pear has been widely cultivated in China. The stone cell content in fruits is a key factor affecting fruit quality in pear, and the formation of stone cells has been associated with lignin biosynthesis. O-Methyltransferase (OMT) is a key enzyme involved in lignin metabolism within the phenylpropanoid pathway. Here, we screened 26 OMT genes from the Pyrus bretschneideri cv. Dangshan Su genome using the DNATOOLs software. To characterize the OMT gene family in pear, gene structure, chromosomal localization, and conserved motifs of PbOMTs were analyzed. PbOMTs were divided into two categories, type I (designated PbCCOMTs) and type II (designated PbCOMTs), indicating the differentiation of function during evolution. Based on the analysis of multiple sequence alignment, cis-element prediction, and phylogenetic relationships, two candidate genes, PbCCOMT1 and PbCCOMT3, were selected for the analysis of temporal and spatial gene expression in pear. The promoter regions of both PbCCOMT1 and PbCCOMT3 contain regulatory motifs for lignin synthesis. Moreover, the two genes show high similarity and close phylogenetic relationships with CCOMTs in other species. Expression analysis showed that transcript levels of two PbCCOMTs were positively associated with the contents of both stone cells and lignin during the development of pear fruit. These results suggest that PbCCOMT1 and PbCCOMT3 are closely associated with lignin biosynthesis. These findings will help clarify the function of PbOMTs in lignin metabolism and to elucidate the mechanisms underlying stone cell formation in pear. PMID- 27706701 TI - Analysis of FKBP10, SERPINH1, and SERPINF1 genes in patients with osteogenesis imperfecta. AB - Osteogenesis imperfecta (OI) is a heterogeneous disorder that causes fragility, deformity, and fractures in bones. A large number of genes that are associated with the disease have been identified in the last decade; this makes the genetic diagnosis of OI more difficult. To improve our knowledge of the genetic mutation profile in OI we used single-stranded conformation polymorphism screening and automated sequencing to investigate the SERPINH1, FKBP10, and SERPINF1 genes, which are related to recessive OI, in 23 unrelated Brazilian patients. Nine rare changes and four common polymorphisms were detected. Most changes were benign genetic variants. In general, changes in the SERPINH1 and SERPINF1 genes were synonymous polymorphisms or missense changes located in non-coding regions. A pathogenic change was found in the FKBP10 gene. The characterization of mutations related to OI in distinct populations can improve our knowledge of the genetic aspects of OI and help us develop molecular strategies for the diagnosis of the disease. PMID- 27706702 TI - Mixed inheritance in the genetic control of ramulosis (Colletotrichum gossypii var. cephalosporioides) resistance in cotton. AB - Ramulosis is one of the most aggressive diseases in cotton, and understanding the genetic control of its resistance is imperative for selecting superior cotton genotypes in breeding programs. This study analyzed the inheritance pattern of this resistance using chi-square goodness-of-fit tests to determine the phenotypic proportions of the F2 generation, and a mixed inheritance approach to jointly model major gene and polygenes effects. F1, F2, Rc1, and Rc2 generations were obtained by crossing resistant (BRS Facual, CNPA 2984, or CNPA 2043) and susceptible (Delta Opal, CNPA 999, or CNPA 2161) genotypes, and were assessed under field conditions with artificial inoculation of the pathogen (Colletotrichum gossypii var. cephalosporioides). Genetic control of the trait varied among the crossings. For Delta Opal x BRS Facual and CNPA 2161 x BRS Facual, phenotypic segregations in the F2 generation did not differ from the expected proportions for the hypothesis of duplicate genes (15:1). For Delta Opal x CNPA 2043, the segregation did not differ from the expected proportions for dominant recessive epistasis (13:3). The hypothesis of genetic control by one major gene was supported only for the Delta Opal x CNPA 2043 crossing. Three other crossings showed evidence of polygenes in the inheritance of the trait. In conclusion, major genes and polygenes are likely involved in the genetic control of ramulosis resistance in cotton. PMID- 27706703 TI - Analysis of allelic variants of rdxA associated with metronidazole resistance in Helicobacter pylori: detection of common genotypes in rdxA by multiplex allele specific polymerase chain reaction. AB - Resistance to metronidazole (Mtz) in Helicobacter pylori is a major problem worldwide, especially in developing countries. Alterations in Mtz nitroreductase enzymes, such as oxygen-insensitive NADPH nitroreductase (RdxA) and NADPH flavin oxidoreductase (FrxA), are the major contributing factors for this resistance. In this study, rdxA and frxA were amplified, sequenced, and analyzed in 34 Mtz resistant H. pylori isolates (MIC >= 8 MUg/mL) using multiple allele-specific polymerase chain reaction (MAS-PCR); this method was developed to target the most common genotypes of rdxA in H. pylori. In this study, the rdxA and frxA genes in Mtz-resistant H. pylori strains displayed a large number of point mutations. The rdxA and frxA genes of Mtz-resistant clinical isolates showed a higher percentage of missense mutations (97.1 and 78.6%, respectively) compared to 26695 reference strains; additionally, missense mutations were more common than frameshift (20.6 and 32.1%) and nonsense mutations (8.8 and 10.7%, respectively) in these genes. The most common missense mutations in rdxA were D 59 N (94.1%), T 31 E (88.2%), and R 131 K (85.3%). The most common missense mutations in frxA were F 72 S (57.1%), G 73 S (57.1%), and C 193 S (53.6%). The developed MAS primers, specific to position 175 and 392 of rdxA, successfully amplified the common alleles and distinguished the variants. MAS-PCR could be a useful tool for epidemiological studies of H. pylori, associated with Mtz resistance. rdxA variants must be screened in order to ensure the effectiveness of Mtz-based H. pylori therapies in developing countries. PMID- 27706704 TI - Chemical and genetic diversity of high-seed-yield sorghum (Sorghum bicolor M.) germplasms. AB - This study evaluated the chemical and genetic diversity of high-seed-yield sorghum germplasms from Korea, the United States, and South Africa. We identified significant differences in the chemical contents of whole plants at the heading stage in all cultivars, including differences in crude protein, fat, fiber, ash, neutral detergent fiber, acid detergent fiber, mineral, and fatty acid contents. Our results suggest that Banwoldang is the most appropriate cultivar for roughage because of its high protein yield. We identified significant differences in the tannin, flavonoid, amylose, mineral, crude fat, fatty acid, and 3 deoxyanthocyanin contents in the whole grain from all cultivars, but not in the mineral or crude fat contents. Tannin levels were generally low. IS645 contained the highest levels of flavonoids and linolenic acid compounds, and Moktak had the highest amylose and deoxyanthocyanidin content in the grain. To assess genetic diversity, we used 10 simple sequence repeat (SSR) primer sets to identify 38 alleles with 3-8 alleles per locus. Based on phylogenetic analysis of the SSR markers, the sorghum cultivars were divided into three major groups. Comparison of clusters based on chemical compositions with those based on SSRs showed that the groups formed by the three native Korean cultivars clustered similarly in molecular dendrograms. Association analysis was conducted for the 10 SSR marker; 48 chemical and growth traits were present for two marker traits (seed color and whole plant fatty acid content) with significant marker-trait associations. These markers could be used to select sorghum cultivars for breeding programs. PMID- 27706705 TI - Methylation differences and expression profiles of the caprine DIO3 gene. AB - DIO3 gene encoding type 3 iodothyronine deiodinase is an imprinted gene, located in the DLK1-DIO3 (delta-like 1 homolog-type 3 iodothyronine deiodinase) imprinted domain, and is potentially involved in degrading excessive amounts of thyroid hormone to protect embryogenesis. However, the underlying regulatory mechanism of the imprinted DIO3 gene expression during fetal and neonatal development in goats has not been elucidated. In this study, we explored the DNA methylation patterns of the caprine DIO3 intragenic CpG island and quantified gene expression level in six tissues from Chinese Nanjiang Yellow 3-day old kids. The expression of the DIO3 gene was determined using quantitative reverse transcription-polymerase chain reactions (qRT-PCRs), while the identification of methylation patterns was determined using bisulfite-sequencing PCRs. Modest, and non-significant (P > 0.05), methylation patterns were noted for the DIO3 CpG island methylation in the brain, heart, liver, kidney, lung, and longissimus dorsi tissues (ranging from 26.48 to 34.92%). The expression level of the DIO3 mRNA was significantly higher (P < 0.05) in the liver tissue than in the other five tissues. Pearson's correlation analysis revealed that there was no significant relationship between methylation and gene expression (P > 0.05), which indicated that the expression of the caprine DIO3 gene was likely modified by other regulatory elements. This study identified DNA methylation and expression patterns of the DIO3 gene in goats and provided insights into further regulatory mechanisms of expression and imprinting in the DLK1-DIO3 domain. PMID- 27706706 TI - Genetic diversity analysis of Varronia curassavica Jacq. accessions using ISSR markers. AB - Varronia curassavica Jacq. is a medicinal and aromatic plant from Brazil with significant economic importance. Studies on genetic diversity in active germplasm banks (AGB) are essential for conservation and breeding programs. The aim of this study was to analyze the genetic diversity of V. curassavica accessions of the AGB of Medicinal and Aromatic Plants of the Federal University of Sergipe (UFS), using inter-simple sequence repeat molecular markers. Twenty-four primers were tested, and 14 were polymorphic and informative, resulting in 149 bands with 97.98% polymorphism. The UPGMA dendrogram divided the accessions into Clusters I and II. Jaccard similarity coefficients for pair-wise comparisons of accessions ranged between 0.24 and 0.78. The pairs of accessions VCUR-001/VCUR-503, VCUR 001/VCUR-504, and VCUR-104/VCUR-501 showed relatively low similarity (0.24), and the pair of accessions VCUR-402/VCUR- 403 showed medium similarity (0.78). Twenty eight accessions were divided into three distinct clusters, according to the STRUCTURE analysis. The genetic diversity of V. curassavica in the AGB of UFS is low to medium, and it requires expansion. Accession VCUR-802 is the most suitable for selection in breeding program of this species, since it clearly represents all of the diversity present in the AGB. PMID- 27706707 TI - Diagnosis and epidemiology of canine leishmaniasis in southeastern Bahia, Brazil. AB - Leishmaniasis is a disease caused by protozoa of the genus Leishmania. Two distinct forms are recognized: visceral leishmaniasis (VL) and cutaneous leishmaniasis (CL). In the Americas, the causative agent of VL is L. infantum chagasi, whereas L. braziliensis is principally responsible for CL. Domestic dogs constitute the main source of VL in urban environments, and have also been implicated in CL epidemiology. We carried out molecular and serological surveys to detect Leishmania infection in dogs from the municipality of Itubera in Bahia, Brazil. Furthermore, we identified risk factors associated with illness in dogs from this locality. Blood samples were collected from 399 dogs and tested using an indirect immunofluorescence assay (IFA) and polymerase chain reaction (PCR) to detect Leishmania spp antibodies and L. infantum chagasi and L. braziliensis DNA, respectively. Dogs were clinically evaluated and tissue samples from those exhibiting skin lesions were examined for parasites. In addition, the dog owners completed an epidemiological questionnaire to identify factors associated with infection. Skin lesions consistent with CL were found on 37 (9.3%) of the evaluated animals, but parasitological examination was negative for all samples. The IFA returned positive results for 60 (15%) dogs. PCR identified DNA from L. braziliensis in 86 (21.6%) animals, where as all samples proved negative for L. infantum chagasi. The 134 dogs (33.6%) testing positive using IFA and/ or PCR were considered infected, and of these, only 13 demonstrated skin lesions. Animals from rural areas were 3.39-times more likely to be infected compared to those in urban environments. PMID- 27706708 TI - Characterization of a novel Cry8Ea3-binding V-ATPase Subunit A in Holotrichia parallela. AB - Several receptor proteins of Cry toxin have been previously identified, including cadherin-like, aminopeptidase N, and alkaline phosphatase. In the present work, a novel binding protein, V-ATPase subunit A (HpVAA), was identified in Holotricia parallela larvae and characterized. We performed reverse transcription-polymerase chain reaction and rapid amplification of cDNA ends technology to obtain the cDNA of the full-length hpvaa. Sequencing analysis showed that the open reading frame of hpvaa (GenBank accession No. KU497557) is 1845 bp long, encoding 614 amino acid residues. The predicted molecular weight and isoelectric point of HpVAA were 67.85 kDa and 4.9, respectively. The HpVAA protein, which includes two putative conserved domains, ATP-synt_ab_N and ATP-synt_ab_C, and a Walker A (GAFGCGKT) motif and a Walker B (SMMAD) motif, possesses the same structural characteristics as V-ATPase subunit A from other insects. The protein was successfully expressed in Escherichia coli, and a ligand blot assay showed binding of the protein with Cry8Ea3 toxin. Transcriptional analysis of hpvaa in different tissues of H. parallela larvae was performed by qRT-PCR, which showed that the relative expression of hpvaa in the Malpighian tubules is higher than that in other tissues. PMID- 27706709 TI - Growth factor progranulin blocks tumor necrosis factor-alpha-mediated inhibition of osteoblast differentiation. AB - Tumor necrosis factor-alpha (TNF-alpha) stimulates osteoclast differentiation and suppresses osteoblast differentiation, leading to bone loss and decreased bone mass in local inflammation areas in patients with rheumatoid arthritis. The growth factor progranulin (PGRN) is expressed in various types of cells and play crucial roles in the pathogenesis of atherosclerosis and arthritis by blocking TNF-alpha. Here, we investigated the role of PGRN in blocking TNF-alpha-mediated inhibition of osteoblast differentiation and the regulatory mechanism. C2C12 stem cell was induced by bone morphogenetic protein-2 (BMP-2) for osteoblast differentiation. A significant increase in ALP activity (P < 0.001), as well as the expression of ColI, Ocn, and Bsp in the induced cells (P < 0.01 and P < 0.001) were observed; the marker gene expression and ALP activity were inhibited by TNF-alpha (P < 0.01 and P < 0.001). PGRN significantly blocks the TNF-alpha mediated inhibition of osteoblast differentiation, evidenced by the ALP activity (P < 0.05 and P < 0.01), Alizarin red staining, the expression of ColI, Ocn, and Bsp (P < 0.05 and P < 0.01) and the osteoblast key transcription factor gene Runx2 (P < 0.01), Osx (P < 0.05), and ATF4 (P < 0.05). Mechanical study indicated that PGRN significantly blocks the TNF-alpha-mediated stimulation of NF-kB signaling (P < 0.01 and P < 0.001). PGRN exerts a protective effect on osteoblast differentiation in an inflammatory environment. Thus, we concluded that the treatment of osteoblasts with PGRN could be used in the future to prevent or treat rheumatoid arthritis-associated bone loss. PMID- 27706710 TI - Investigating the association between XRCC1 gene polymorphisms and susceptibility to gastric cancer. AB - We carried out a hospital-based case-control study to investigate the role of XRCC1 gene Arg399Gln, Arg280His, and Arg194Trp polymorphisms in susceptibility to gastric cancer. A total of 214 gastric cancer patients and 247 control subjects were recruited between March 2013 and March 2015, and polymorphism genotype frequencies were determined by polymerase chain reaction-restriction fragment length polymorphism. Using the chi-square test, we detected statistically significant differences in age (chi-square = 22.25, P < 0.001), gender (chi square = 6.74, P = 0.01), and family history of cancer (chi-square = 4.73, P = 0.03) between the case and control groups. Logistic regression analysis revealed that the XRCC1 Arg194Trp TT genotype conferred increased susceptibility to gastric cancer compared to the CC genotype [odds ratio (OR) = 2.38, 95% confidence interval (CI) = 1.28-4.49]. Moreover, individuals carrying the T allele of this variant were found to be at moderately increased risk of this disease (OR = 1.56, 95%CI = 1.16-2.09). However, the XRCC1 Arg399Gln and Arg280His polymorphisms were shown to have no influence on the development of gastric cancer. In conclusion, we suggest that the XRCC1 gene Arg194Trp polymorphism is associated with gastric cancer susceptibility in the Chinese population. PMID- 27706711 TI - Comparative analysis of short tandem repeat data obtained by automated and gel electrophoresis techniques. AB - Short tandem repeats (STRs) are commonly used as genetic markers. The detection and analysis of STRs can be used to gather information on polymorphisms of interest to forensic geneticists. Denaturing polyacrylamide gel electrophoresis (PAGE) is an affordable method for the detection of minor sequence changes in DNA, while capillary electrophoresis (CE) is the gold standard for genotyping analysis. This appears to be the first study to directly compare data obtained using the two electrophoretic techniques. We analyzed genomic DNA from 209 individuals to compare genotyping results from seven Combined DNA Index System (CODIS) STR markers obtained by both techniques. The automated electrophoresis was carried out using a MegaBACETM 1000 DNA analysis system. Full concordance was found in 1297 of 1308 STR allele calls. Kappa and McNemar-Bowker tests indicated that there were no statistically significant differences between the results from the two methods. There was no statistically significant difference in precision between denaturing PAGE followed by silver nitrate staining, despite a longer protocol, compared with CE when applied to population studies. STR allele frequency data from non-automated genotyping techniques seem to be just as reliable as from automated genotyping methods. PMID- 27706712 TI - Contributions of polymorphisms in miR146a, miR196a, and miR499 to the development of hepatocellular carcinoma. AB - Hepatocellular carcinoma is one of the most common malignant tumors worldwide; it is estimated that there were 782,000 new cases in 2012. MicroRNAs (miRNAs) play an important role in carcinogenesis by regulating oncogenes and tumor suppressors. We investigated the role of miR-146a, miR-196a2, and miR-499 polymorphisms in the risk of hepatocellular carcinoma in a Chinese population. Hepatocellular carcinoma patients (175) and healthy controls (302) were recruited between April 2013 and March 2015. Genotype analysis of miR-146a, miR-196a2, and miR-499 polymorphisms was carried out by polymerase chain reaction-restriction fragment length polymorphism. There was a significant difference between the genotype distribution of miR-196a2 in hepatocellular carcinoma patients and controls (X2 = 17.23, P < 0.001). CG and GG miR-146a genotypes significantly elevated the risk of hepatocellular carcinoma compared with the CC genotype, with adjusted ORs (95%CI) of 3.05 (1.07-8.70) and 4.96 (1.64-14.97), respectively. In the recessive model, the CG + GG genotype had a 3.75-fold risk of hepatocellular carcinoma compared with the CC genotype, with an adjusted OR (95%CI) of 3.75 (1.39-10.11). However, no significant association was observed between miR-196a2 and miR-499 variants and risk of hepatocellular carcinoma in the co-dominant, dominant, and recessive models. The miR-146a polymorphism is a G to C substitution that causes a mismatch in the stem-loop of miRNA, which influences how the expression and transcriptional regulation of miRNA affects its target genes. Our study revealed that the GG and CG genotypes of miR-146a increased the risk of hepatocellular carcinoma in the Chinese population.

AB - Arachis pintoi and A. repens are legumes with a high forage value that are used to feed ruminants in consortium systems. Not only do they increase the persistence and quality of pastures, they are also used for ornamental and green cover. The objective of this study was to analyze microsatellite markers in order to access the genetic diversity of 65 forage peanut germplasm accessions in the section Caulorrhizae of the genus Arachis in the Jequitinhonha, Sao Francisco and Parana River valleys of Brazil. Fifty-seven accessions of A. pintoi and eight of A. repens were analyzed using 17 microsatellites, and the observed heterozygosity (HO), expected heterozygosity (HE), number of alleles per locus, discriminatory power, and polymorphism information content were all estimated. Ten loci (58.8%) were polymorphic, and 125 alleles were found in total. The HE ranged from 0.30 to 0.94, and HO values ranged from 0.03 to 0.88. By using Bayesian analysis, the accessions were genetically differentiated into three gene pools. Neither the unweighted pair group method with arithmetic mean nor a neighbor-joining analysis clustered samples into species, origin, or collection area. These results reveal a very weak genetic structure that does not form defined clusters, and that there is a high degree of similarity between the two species. PMID- 27706714 TI - Correlation between serum level of chemokine (C-C motif) ligand 18 and poor prognosis in breast cancer. AB - In this study, we investigated the correlation between serum chemokine (C-C motif) ligand 18 (CCL-18) and the prognosis as well as clinical characteristics of breast cancer. Blood samples from 207 breast cancer patients, 126 individuals with benign breast tumors, and 93 healthy women were collected. Serum CCL-18 expression was detected by enzyme-linked immunosorbent assay. Mann-Whitney's U tests were carried out to analyze the relationship between serum CCL-18 and clinicopathological variables. The Kaplan-Meier method was used to evaluate the overall survival (OS), whereas differences between groups were analyzed by log rank tests. The COX proportional hazard regression model was used to determine the association between clinicopathological characteristics and survival. We found that serum CCL-18 was significantly higher in breast cancer patients (290.06 +/- 89.52 pg/mL) as compared to that in individuals with benign tumors (170.14 +/- 26.57 pg/mL) or healthy women (119.36 +/- 38.77 pg/mL) (P < 0.05). Serum CCL-18 was correlated with clinical cancer stages (P = 0.007), and was associated with advanced cancer stage (P < 0.05). The 5-year OS rate of breast cancer patients with high serum CCL- 18 was 35.9% (HR = 3.908, 95%CI = 2.546 12.090, P < 0.05), which was significantly lower as compared to that for patients with low serum CCL-18 (85.5%). Based on our results, we conclude that CCL-18 is a prognostic biomarker in patients with advanced breast cancer in Chinese patients. PMID- 27706715 TI - Effects of MMP-1 and MMP-3 gene polymorphisms on gene expression and protein level in lumbar disc herniation. AB - The aim of this study was to identify the possible correlation between polymorphisms in matrix metalloproteinase (MMP)-1 and MMP-3 and their corresponding protein levels in disc tissues obtained from patients with lumbar disc herniation (LDH) using biochemical and immunohistochemical analyses. Blood and disc samples were obtained from 100 patients with LDH who underwent a lumbar microdiscectomy. Based on the radiological degeneration, the patients were diagnosed with grade 2, 3, or 4 LDH. MMP-1 -1607 1G/2G and MMP-3 -1171 5A/6A were analyzed by real-time polymerase chain reaction. The expressions of MMP-1 and MMP 3 were detected by biochemical and immunohistochemical analyses. We found no association between the MMP-1 polymorphism and disc degeneration and MMP-1 expression. However, patients expressing the 6A/6A and 5A/6A alleles of MMP-3 11715A/6A showed higher MMP-3 expression, compared to those expressing the 5A/5A genotype. Additionally, the radiological degeneration grades were correlated with the histological degeneration scoring. Protein levels and immunopositive cell rates of MMP-1 and MMP-3 were associated with disc degeneration grades. Moreover, the MMP-1 and MMP-3 expression and the histological and radiological scores were positively correlated and the MMP-3 -11715A/6A polymorphism was associated with MMP-3 expression in herniated disc tissues. This study is the first to investigate polymorphisms in MMP-1 and MMP-3, as well as their corresponding protein expressions. We also quantified an association between the radiological degeneration grades and MMP-1 and MMP- 3 expression. Further genomic studies on MMPs could focus on the utilization of MMP-1 and MMP-3 as markers for the prevention and treatment of this disease. PMID- 27706716 TI - Expression patterns of two heat-shock cognate 70 genes during immune responses and larval development of the Chinese mitten crab Eriocheir sinensis. AB - Two heat-shock protein (HSP) 70 family transcripts, heat-shock protein 70 cognate 5 and heat-shock protein 70 cognate 3 (designated as EsHSC70-5 and EsHSC70-3, respectively), were isolated from the Chinese mitten crab Eriocheir sinensis and their expression profiles were evaluated for their responsiveness to larval development and immune challenge in adult crabs. The HSPs exhibited 45-89% identity with other heat-shock proteins, and they shared similar structural features. EsHSC70 mRNA expression was detected not only during infection but also during the developmental larval stages. The EsHSC70s were enriched, and their expression fluctuated during early development. EsHSC70 mRNA expression was significantly induced by Vibrio parahaemolyticus challenge in all of the tissues studied (P < 0.05). Expression of EsHSC70 mRNA in the hepatopancreas and at the early zoeal stages was particularly pronounced, and the two EsHSC70s exhibited differential expression patterns both chronologically and spatially. The EsHSC70 5 mRNA level was significantly downregulated in the intestine and gills compared to that in controls at nearly all time points, and was expressed at a lower level after the bacterial challenge, indicating that EsHSC70-5 and EsHSC70-3 respond to immune challenges. The stage-specific enrichment of EsHSC70 transcripts in crabs suggests that these stress proteins play an essential role during brachyurization events. PMID- 27706717 TI - HPV genotyping and p16 expression in Xingu Indigenous Park, Brazil. AB - The association between high-risk human papillomavirus (HPV) genotypes and p16 expression in indigenous women from the Xingu Indigenous Park, Brazil, was unknown. This study evaluated p16 expression in women with a histological diagnosis of cervical intraepithelial neoplasia (CIN) 3 or higher and correlated this expression with HPV genotypes to determine possible discrepancies in the expression of this marker. We evaluated 37 previously collected samples with different HPV genotypes and high-grade lesions diagnosed based on cytology, histology, and colposcopy. Immunohistochemical analysis was performed using paraffin-embedded tissue sections and the CINtec(r) Histology Kit. p16 protein expression was investigated by immunostaining with an anti-p16 antibody. HPV genotyping was performed by reverse hybridization. The age of the study population ranged from 22-75 years (43.81 +/- 15.89 years) and parity ranged from 1-11 (5.92 +/- 2.58). Thirteen different HPV genotypes were found using the INNO LiPA kit. Single and multiple infections by HPV were found with prevalence of single infections (P = 0.029). Comparison between HPV genotype and simple or multiple infections was highly significant; it was observed more HPV 52 followed by HPV 16 in single infections (P < 0.001). p16 expression was predominantly diffuse, which was observed in 91.7% of lesions, whereas 8.3% were focal (P < 0.001). HPV 52, HPV 16 and 31 were the most prevalent HPV types in high-grade CIN in these indigenous women. Diffuse p16 expression in high-grade CIN was not influenced by the viral genotype; however, more studies are necessary to further our understanding of this restricted group. PMID- 27706718 TI - Changes in methylation of genomic DNA from chicken immune organs in response to H5N1 influenza virus infection. AB - DNA methylation is an important epigenetic modification in eukaryotes, which plays a significant role in regulating gene expression. When the host is invaded by the influenza virus, gene expression is regulated via changes in DNA methylation levels or patterns, leading to the activation or suppression of relevant signaling pathways or networks, triggering a series of immune responses against viral invasion. Here, we investigated the changes in genomic DNA methylation in the immune organs of chicken infected with H5N1 influenza virus. Genome-wide DNA methylation levels in the spleen, thymus, and bursa of Fabricius of specific pathogen-free (SPF) chicken infected with the Guangdong (G-H5N1) and Anhui (A-H5N1) H5N1 strains, and water (control) were analyzed by fluorescence labeled methylation-sensitive amplified polymorphism (F-MSAP). The results indicated that total DNA methylation levels did not differ between spleen genomic DNA in chicken treated with different viral strains and the control (P > 0.05). However, the total DNA methylation levels were significantly upregulated in the thymus (P < 0.01) and bursa (P < 0.05) of chicken in the A-H5N1 group compared to those in the G-H5N1 and control groups. These results provide a basis for the screening of avian influenza-resistance genes or methylation markers, analyzing the epigenetic regulation mechanisms of avian influenza, and performing selective breeding for disease resistance. PMID- 27706719 TI - Interleukin-6 -572G/C polymorphism and prostate cancer susceptibility. AB - Strong evidence suggests that cancer-associated inflammation promotes tumor growth and progression, and interleukin-6 (IL6) is an important modulator of inflammation. However, the roles of IL6 and mutations of its corresponding gene in prostate cancer have not been clearly documented. We retrieved data from the Oncomine database concerning IL6 expression in prostate cancer and its role in prostate-specific antigen (PSA) recurrence. We also performed a case-control study of the IL6 -572G/C polymorphism (rs1800796) in 236 sporadic prostate cancer patients and 256 healthy controls from a southern Han Chinese population. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated to assess the association between rs1800796 and prostate cancer susceptibility. A dual luciferase reporter assay was used to test the transcriptional activity of the IL6 promoter G and C alleles. IL6 was overexpressed in prostate cancer tissues compared to normal tissues, especially in those with higher Gleason scores. Moreover, elevated IL6 expression was associated with high PSA recurrence rate in Oncomine data. Our case-control study demonstrated that compared with the -572C allele, the -572G allele conferred a borderline increased risk of prostate cancer (OR = 1.31, 95%CI = 0.99-1.74, P = 0.061). This was more pronounced in the subgroup of individuals having never smoked (OR = 1.85, 95%CI = 1.07-3.22). Moreover, the G allele showed increased activity relative to the C allele in the dual-luciferase reporter assay. Our results suggest that the -572G/C polymorphism may be associated with IL6 expression, which in turn plays a role in prostate cancer development. PMID- 27706720 TI - Phylogenetic analysis of the Mongolian gerbil (Meriones unguiculatus) from China based on mitochondrial genome. AB - Meriones unguiculatus (Gerbillinae, Rodentia) is widely used as an animal model of human disease. Here, we provide the first report of the complete mitochondrial genome sequence of M. unguiculatus (GenBank accession Nos. KF425526 and NC_023263). The sequence contained the conserved vertebrate pattern of 13 protein coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and 1 major noncoding region. We identified one extended termination-associated sequence and one conserved sequence block in the non-coding region. The putative origin of replication for the light strand (OL) was 35 bp long. The OL stem and adjacent sequences were highly conserved, but the loop region differed from those of other rodent species. Base composition and codon usage of the 13 protein-coding genes in M. unguiculatus were compared with those of 23 rodent species with previously sequenced mitochondrial genomes. An A+T content of 63.0% was present in M. unguiculatus; this is similar to the Murinae average (62.4 +/- 0.8%) and falls between the average for Mus musculus (63.1 +/- 0.1%) and Rattus sp (61.7 +/- 0.4%). The AT and GC skew values of M. unguiculatus were 0.035 and -0.28, respectively, similar to those of Cricetinae species (0.057 +/- 0.05 and -0.31 +/ 0.05). The codon families exhibited similar abundance in all 24 species. Analysis of phylogenetic relationships with 23 other rodent species using neighbor-joining and maximum likelihood protocols and the 12 protein-coding regions on the H strand showed that M. unguiculatus should be classified as genus Meriones, sub-family Gerbillinae, family Muridae. PMID- 27706721 TI - Correlation between polymorphisms in the estrogen receptor alpha gene and coronary heart disease: A meta-analysis. AB - The aim of this study was to conduct a systematic evaluation the correlation between polymorphisms in the estrogen receptor alpha gene (ESRalpha) and coronary heart disease susceptibility. Case-control studies until August 2015 analyzing the correlation between the ESRalpha PvuII T/C polymorphism and coronary heart disease were obtained from various electronic databases (CBM, CNKI, Wanfang Data, VIP, and MEDLINE, Cochrane Library, Embase, Springer, and Ovid. The data obtained from these studies were evaluated and valid data was extracted. A meta-analysis was performed using RevMan 5.0. Eleven cases, comprising 1742 patients with coronary heart disease and 2012 controls, that conformed to the inclusion criteria set in this study were extracted. The results of our meta-analysis indicated that the C and T alleles, the TC+CC and TT genotypes, and the CC and TT+TC genotypes did not differ significantly. The results of this meta-analysis confirmed that there was no correlation between polymorphisms in ESRalpha and coronary heart disease susceptibility in the Chinese population. PMID- 27706722 TI - Bone morphogenetic protein 9 facilitates osteocarcinoma cell apoptosis and inhibits in vivo tumor growth. AB - Osteosarcoma (OS) causes millions of death worldwide and, since there is no effective therapy, it is necessary to identify the molecular mechanism of OS, which can direct the development of new therapies. This study investigated the role of bone morphogenetic protein 9 (BMP9), a member of the transforming growth factor (TGF)-beta family, in OS development. This study first examined BMP9 expression in tissue from OS patients and normal subjects. The OS cell line (MG63) and tumor cells from OS patients were then transfected with BMP9 and cell proliferation and apoptosis were assessed. Western blot and reverse transcription polymerase chain reaction were used to study the expression of cancer-related genes [B cell lymphoma (Bcl)-2, cleaved Caspase-3, Caspase-9, and poly ADP-ribose polymerase]. To confirm the in vivo impact of BMP9, mice were transplanted with OS tumor cells and then treated with BMP9 carried in attenuated Salmonella enterica serovar Typhimurium. Our study found that the OS tumor tissue had a lower expression of BMP9 compared to normal tissue. Transfection of BMP9 in OS and MG63 cells inhibited cell growth and promoted apoptosis. In vitro studies showed a decrease in Bcl-2 gene expression and an increase in Cyto-c, Caspase-3, and Caspase-9 expression. In vivo studies indicated that consistent treatment with BMP9 in OS mice results in inhibition of tumor growth. This study shows that BMP9 inhibition is associated with OS development and that enhanced expression of BMP9 may be a potential treatment method for OS. PMID- 27706723 TI - Association between functional polymorphisms in the nitric oxide synthase 3 gene and pediatric acute respiratory distress syndrome. AB - Nitric oxide mediates multiple physiological functions, including neurotransmission, immune regulation, angiogenesis, antiplatelet activity, and surfactant maturation or secretion. Mice deficient in the nitric oxide synthase 3 (NOS3) gene displayed defective lung vascular development and fatal respiratory distress. Polymorphisms in NOS3 have been reported to be associated with respiratory distress syndrome (RDS). The role of NOS3 polymorphisms as a risk factor for pediatric acute respiratory distress syndrome (PARDS) was evaluated by analyzing the possible functional single nucleotide polymorphisms (SNPs) in the regulatory and coding regions of NOS3. Samples from 216 PARDS patients and 225 healthy control subjects were genotyped at 4 SNP loci (rs11771443 and rs3918188 in the promoter region, rs1799983 in exon 7, and rs7830 at the intron24-exon23 boundary). Statistically significant differences were observed in the allelic or genotypic frequencies of the rs1799983 and rs11771443 polymorphisms in NOS3. The T and G alleles of rs1799983 and rs11771443 were associated with a significantly higher risk of PARDS compared to the C allele (P = 0.030) and the T allele (P = 0.004), respectively. Strong linkage disequilibrium was observed in one block (D' > 0.9). Subjects with PARDS displayed significantly fewer T-C haplotypes (P = 0.013) in block 1 (rs1799983-rs11771443). These findings indicate that NOS3 polymorphisms play a definitive role in PARDS, and therefore may be useful for future genetic or neurobiological studies on RDS. PMID- 27706725 TI - Effect of pregnane X receptor polymorphisms on tacrolimus blood concentrations and the resulting adverse reactions in kidney transplantation recipients. AB - We investigated the effect of pregnane X receptor (PXR) polymorphisms on tacrolimus (FK506) blood trough concentrations and the associated adverse reactions in kidney transplantation recipients (KTRs). Polymerase chain reaction (PCR)-restriction fragment length polymorphism was used to detect the genotypes of single nucleotide polymorphism loci in 336 KTRs. The PXR six-base deletion mutation was classified using specific allele PCR, and the FK506 blood trough concentration in the KTRs was measured by chemiluminescent microparticle immunoassay. There were significant differences in adverse reactions resulting from FK506 in age, weight, body mass index (BMI) and treatment course (P < 0.05). Logistical regression revealed that the FK506 treatment course and BMI were risk factors for hyperlipidemia, and the risk of hyperlipidemia increased 27.534 times when the BMI was less than 18.5. Moreover, age was also a risk factor leading to hyperglycemia. FK506 blood trough concentration and C0/D value had an impact on adverse reactions induced by hyperglycemia. The KTRs' PXR rs3842689, rs6785049, and rs1523127 mutation frequencies were 26.07, 11.79, and 16.07%, respectively. There was no statistically significant difference in the mutation frequency of each locus between the control group and the adverse reaction groups. Therefore, rs3842689, 7635G>A (rs6785049), and 24381C>A (rs1523127) PXR polymorphisms have no obvious impact on FK506; furthermore, the PXR rs3842689 wild-type homozygous WW genotype is a risk factor of FK506 and results in gastrointestinal reactions. PMID- 27706724 TI - Clinical study of the correlation between complement factor H polymorphism and age-related macular degeneration. AB - This study aimed to investigate the correlation between age-related macular degeneration (AMD) of the liver-kidney yin-deficiency type and complement factor H (CFH) polymorphism, and to determine whether the C allele of the T1277C (Y402H) variant is a risk factor for this condition. We performed a case-control investigation of 60 patients with liver-kidney yin-deficiency AMD and 60 normal control subjects. Peripheral blood was collected from each participant for DNA extraction. Following amplification by polymerase chain reaction, the DNA samples were sequenced, and polymorphism of the CFH gene was examined. Data were analyzed with the chi-square test, with P < 0.05 signifying statistical significance. The frequency of the C allele was significantly higher in the wet than in the dry AMD group (P = 0.044). In addition, the TC and CC genotypes were markedly more common in the former than in the control group (P = 0.013), and there was a significant difference in the distribution of the T and C alleles between wet AMD patients and control subjects (P < 0.05). Based on this, we conclude that liver-kidney yin deficiency AMD is associated with the C allele and TC and CC genotypes of the CFH Y402H polymorphism. Among patients with this condition, CFH genotypes were normally distributed. The principal CFH genotypes that induce liver-kidney yin deficiency AMD are the mutant homozygote CC and heterozygote TC forms. Moreover, C allele carriers are at higher risk of developing this disease. PMID- 27706726 TI - Isolation and characterization of microsatellite loci in Sisyrinchium (Iridaceae) and cross amplification in other genera. AB - Recent phylogenetic studies on Sisyrinchium strongly suggest that species classified in section Hydastylus and section Viperella belong to a single group of plants in recent adaptive radiation (Clade IV). These species neither present clear morphological differentiation among them nor show clear identification using DNA barcode markers. Thus, the main goal of this study was to develop a set of polymorphic microsatellite markers compatible for representative species of both sections to ensure variability that could be revealed by SSR markers. Therefore, microsatellite primers were isolated and characterized for Sisyrinchium palmifolium and S. marchioides. In addition, transferability of the developed primers was tested in Iridoideae, primarily in closely related species of Sisyrinchium. Sixteen microsatellite loci were developed from enriched genomic libraries, of which ten were polymorphic. GST values indicated higher differentiation among subpopulations of S. palmifolium than those from S. marchioides. Major transferability was obtained using primers isolated from S. marchioides. All primers exhibited higher rates of cross-amplification for species belonging to Clade IV of Sisyrinchium, as well as to the genera Calydorea and Herbertia. These developed microsatellite markers can be used as an efficient tool for characterization of genetic variability in species belonging to Iridoideae, as well as for studies on population dynamics, genetic structure, and mating system in other Sisyrinchium species. PMID- 27706727 TI - A glimpse of the endophytic bacterial diversity in roots of blackberry plants (Rubus fruticosus). AB - The aim of this study was to explore the diversity of culturable bacterial communities residing in blackberry plants (Rubus fruticosus). Bacterial endophytes were isolated from plant roots, and their 16S rDNA sequences were amplified and sequenced. Our results show that the roots of R. fruticosus exhibit low colony forming units of bacterial endophytes per gram of fresh tissue (6 x 102 +/- 0.5 x 102). We identified 41 endophytic bacterial species in R. fruticosus by BLAST homology search and a subsequent phylogenetic analysis, belonging to the classes Actinobacteria, Bacilli, Alfaproteobacteria, Betaproteobacteria, and Gammaproteobacteria. Predominantly, genera belonging the Proteobacteria (Burkholderia, 29.4%; Herbaspirillum, 10.7%; Pseudomonas, 4.9%; and Dyella, 3.9%), Firmicutes (Bacillus, 42.1%), and Actinobacteria (two isolates showing high identity with the Streptomyces genus, 1.9%) divisions were identified. Fifty percent of the bacterial endophytes produced the phytohormone indole-acetic acid (IAA), eleven of which exhibited higher IAA production (>5.8 mg/mL) compared to the plant growth-promoting strain, Pseudomonas fluorescens UM270. Additionally, the endophytic isolates exhibited protease activity (22%), produced siderophores (26.4%), and demonstrated antagonistic action (>50% inhibition of mycelial growth) against the grey mold phytopathogen Botrytis cinerea (3.9%). These results suggested that field-grown R. fruticosus plants contain bacterial endophytes within their tissues with the potential to promote plant growth and display antagonism towards plant pathogens. PMID- 27706728 TI - Associations of serotonin receptor gene HTR3A, HTR3B, and HTR3A haplotypes with bipolar disorder in Chinese patients. AB - Single nucleotide polymorphisms (SNPs) in HTR3A and HTR3B have been reported to be associated with bipolar disorder in European and Japanese populations. We explored the roles of 21 tag SNPs in HTR3A and HTR3B in susceptibility to bipolar disorder in a Chinese cohort. Twenty-one Tag SNPs were genotyped in a study consisting of 130 patients with bipolar disorder, who visited Shandong Mental Health Center between June 2013 and May 2014, and 109 healthy individuals as controls. All of the tag SNPs were genotyped using Sequenom MassArray matrix assisted laser desorption/ionization time of flight spectrometry. Plink 1.07, Haploview 4.2, and SPSS 20.0 were used for the analysis of the genotypes and the associations of the haplotypes with bipolar disorder. Association analyses of tag SNPs detected significant associations with the A allele in HTR3A rs1176719 (P = 0.030) and the C allele in HTR3A rs1176713 (P = 0.048). Haplotype-based association analyses indicated a statistically significant (P = 0.035) five-SNP haplotype (rs1062613:C, rs11604247:C, rs1176722:G, rs2276302:A, rs1176719:G) of linkage disequilibrium in block 3. Analysis of our small Chinese sample revealed a significant association of HTR3A with bipolar disorder, but yielded no evidence of an association between HTR3B and bipolar disorder. Furthermore, evidence for an association was found for a haplotype of HTR3A. Studies with larger Chinese samples are needed to verify our findings. PMID- 27706729 TI - Combining abilities for agronomic traits and marker-assisted selection for Potato virus X and Potato virus Y resistance. AB - Disease-resistant potato cultivars with good tuber appearance and desirable agronomic traits are essential for meeting the demands of producers and the market. Attaining these cultivars is the focus of potato breeding programs whose aim is to benefit the productive chain. The purpose of this study was to estimate combining abilities and evaluate potato clones based on tuber appearance, yield, and resistance to the PVY and PVX viruses. Crosses between four commercial cultivars of potato with good tuber appearance were performed, using eight clones with proven resistance to PVY and PVX from the breeding program of UFLA. The clones obtained were evaluated for agronomic traits, tuber appearance, and the presence of both Ryadg and Rx1 alleles, which confer extreme resistance to the PVY and PVX viruses, respectively. The independent culling level method was used to select genotypes of commercial interest, as well as to estimate the combining abilities of the parents. We identified clones carrying the Ryadg and Rx1 alleles with agronomic traits suitable for the fresh market and for processing. The BRS Ana cultivar and CMA-399 and CMA-385 clones showed positive effects on general combining ability (GCA) for tuber yield, while the Monalisa cultivar showed positive effects on GCA for general tuber appearance. PMID- 27706730 TI - Cytogenetic evaluation of cataract patients occupationally exposed to ionizing radiation in northeast China. AB - Long-term radiation exposure is hazardous to health; late-onset effects of exposure to ionizing radiation (IR) pose risks to the lens, and are associated with other non-cancerous diseases. Individuals occupationally exposed to low-dose IR are prone to developing eye cataracts. Cytogenetic evaluations suggest that IR is associated with chromosomal aberrations in occupationally exposed individuals. However, data regarding the association between chromosomal aberrations in cataract patients and occupational exposure to IR is scarce. Therefore, we aimed to report the characteristics of chromosomal aberrations in cataract patients from a Chinese population, occupationally exposed to IR. We found that the average age and frequency of numerical chromosomal aberrations were significantly lower in the exposed patients as compared with that in the non-exposed patients. In addition, the frequencies of dicentric and acentric chromosomes were significantly higher in the exposed patients as compared with those in the non exposed patients. Therefore, chronic occupational exposure to IR affects cataract development in the Chinese population. The age of cataract patients exposed to IR was significantly lower than the age of cataract onset in normal individuals. Based on this study, we suggest that there is an urgent need for improved radiation safety and eye protection in individuals exposed to IR in the work place. PMID- 27706731 TI - Association of CD4 SNPs with fat percentage of Holstein cattle. AB - Cluster of differentiation 4 gene (CD4) is well known for its role in immunity, but its effects on production traits remain to be elucidated. The present study was designed to explore single nucleotide polymorphisms (SNPs) in the exons, flanking introns, and promoter of CD4, as well as to analyze their effects on milk production traits (percentage of protein, fat, and lactose; mastitis indicator traits somatic cell count; and somatic cell score). A total of 10 SNPs, including eight in the exon and two in the intron regions, were identified using pooled DNA sequencing. These SNPs were screened in a population of 258 Chinese Holstein using the SNaPshot technique. We analyzed the effects of SNPs, parity, herd, year, and season of calving on the production and mastitis indicator traits. Our analysis revealed two haplotypes and strong linkage disequilibrium (D' > 0.97) among all SNPs. All 10 SNPs were significantly associated with fat percentage (P < 0.01). Cows homozygous for the wild-type genotypes had higher fat percentages than those with the other genotypes. The dominant and additive effects were also significant for fat percentage (P < 0.05). These results suggest that CD4 plays a role in production traits as well as in immune function. The identified SNPs could be used as genetic markers for selection of dairy cows with improved fat percentage. We propose further studies of these SNPs in a larger population as well as further investigations of the function of this gene.

AB - The effects of muscle-specific miRNAs in the repair of exercise-induced muscle injury were investigated by examining the changes in their expression and that of the target genes in rat skeletal muscle. Two-month-old agile male rats were randomly divided into exercise and static control groups, the former subdivided into 0-h, 6-h, 12-h, 1-day, 2-day, 3-day, 1-week, and 2-week groups based on time after exercise. Left gastrocnemii of rats were hematoxylin-eosin stained whereas the right gastrocnemii were used for expression analysis of muscle-specific miRNAs (miR-1 and miR-206) and their target genes, Cx43 and HDAC. Cellular swelling and increased cell volume and intercellular spaces were observed histologically in the 0-h group. Unlike the control group, cells continued to swell whereas intercellular spaces decreased slightly, in the 6-h, 12-h, 1-day, and 2-day groups. Cell swelling was most serious in the 3-day group. In the 1 week group, inflammatory cell infiltration decreased and in the 2-week group, repair was almost complete. The differences in miR-1 expression between the groups were neither obvious nor significant. miR-206 expression increased; however, it differed significantly from that in group C only in the 1-week group. Cx43 and HDAC4 mRNA expression first decreased and then increased compared to that in the control group; differences in HDAC4 mRNA expression were significant in the 1-week group. Compared to the control group, the differences in Cx43 protein levels were significant in the 0-h and 3-day groups. Thus, miR-206 and Cx43 are involved in the repair of exercise-induced muscle injury. PMID- 27706733 TI - Selection index using the graphical area applied to sugarcane breeding. AB - This study aimed to develop a multivariate selection index based on the graphical area of a polygon formed by standardized values, also known as radar chart. This methodology may be used to assist selection of superior genotypes in sugarcane breeding programs. Seven technological traits in 37 sugarcane genotypes were evaluated. An area index (AI) was constructed and the resulting polygon areas were used to rank genotypes under selection. In this study, we propose the use of restricted maximum likelihood to estimate genetic parameters and mixed model equations to predict genotypic and breeding values. The area of each polygon was calculated for phenotypic, genotypic, and estimated breeding values. Thereby, the genotypes with larger area can be selected based on a detailed a posteriori evaluation of the radar charts. The proposed AI can be adjusted based on the breeders' specific interests, it is perfectly useful in other crops, and may also be applied to studies on genotype-environment interactions. Moreover, AI is a powerful tool that can evaluate trait stability of genotypes based on slight differences in the area formed by each genotype. Hence, this method is easy to apply and shows great potential for use in sugarcane breeding programs as well as in other breeding programs. PMID- 27706734 TI - Association between miR-137 polymorphism and risk of schizophrenia: a meta analysis. AB - miR-137, a brain-enriched microRNA, is involved in the control of neuronal proliferation, differentiation, and dendritic arborization, all of which are important for proper neurogenesis and relevant to schizophrenia. miR-137 is also known to regulate many genes implicated in schizophrenia risk. Although reports have associated the miR-137 polymorphism rs1625579 with this disease, their results have been inconsistent. The aim of this meta-analysis was to evaluate the relationship between rs1625579 and schizophrenia. Data were obtained from an electronic database, and pooled odds ratios (ORs) with 95% confidence intervals (95%CI) were used to test the association using the RevMan 5.3 software. Twelve case-control studies comprising 11,583 cases and 14,315 controls were included. An estimated lambda value of 0.46 was recorded, suggesting that a codominant model of inheritance was most likely. A statistically significant association was established under allelic (T vs G: OR = 1.15, 95%CI = 1.10-1.21, P < 0.001) and homogeneous codominant models (TT vs GG: OR = 1.32, 95%CI = 1.13-1.54, P < 0.001), but no such relationship was detected using the heterogeneous codominant model (GT vs GG: OR = 1.14, 95%CI = 0.97-1.34, P = 0.11). This meta-analysis demonstrates that the rs1625579 miR-137 genetic variant significantly increases schizophrenia risk. PMID- 27706735 TI - Development of a transposon-based marker system for mutation breeding in sorghum (Sorghum bicolor L.). AB - Under certain circumstances, transposable elements (TE) can create or reverse mutations and alter the genome size of a cell. Sorghum (Sorghum bicolor L.) is promising for plant transposon tagging due to its small genome size and its low content of repetitive DNA. We developed a marker system based on targeted region amplification polymorphisms (TE-TRAP) that uses the terminal inverted repeats (TIRs) of transposons. A total of 3816 class 2 transposons belonging to the PIF/Harbinger family were identified from the whole sorghum genome that produced five primers, including eight types of TIRs. To define the applicability and utilization of TE-TRAP, we used 21 individuals that had been bred after ?-ray irradiation. In total, 31 TE-TRAP, 16 TD, and 21 AFLP primer combinations generated 1133, 223, and 555 amplicons, respectively. The percent polymorphic marker was 62.8, 51.1, and 59.3% for the TE-TRAP, TD, and AFLP markers, respectively. Phylogenetic and principal component analyses revealed that TE-TRAP divided the 21 individuals into three groups. Analysis of molecular variance suggested that TE-TRAP had a higher level of genetic diversity than the other two marker systems. After verifying the efficiency of TE-TRAP, 189 sorghum individuals were used to investigate the associations between the markers and the ?-ray doses. Two significant associations were found among the polymorphic markers. This TE-based method provides a useful marker resource for mutation breeding research. PMID- 27706736 TI - Morphological and molecular characterization of Cladosporium cladosporioides species complex causing pecan tree leaf spot. AB - The objective of this study was to characterize species of the Cladosporium cladosporioides complex isolated from pecan trees (Carya illinoinensis) with symptoms of leaf spot, based on morphological and molecular approaches. Morphological attributes were assessed using monosporic cultures on potato dextrose agar medium, which were examined for mycelial growth, sporulation, color, and conidia and ramoconidia size. Molecular characterization comprised isolation of DNA and subsequent amplification of the translation elongation factor 1alpha (TEF-1alpha) region. Three species of the C. cladosporioides complex were identified: C. cladosporioides, Cladosporium pseudocladosporioides, and Cladosporium subuliforme. Sporulation was the most important characteristic differentiating species of this genus. However, morphological features must be considered together with molecular analysis, as certain characters are indistinguishable between species. TEF-1alphacan be effectively used to identify and group isolates belonging to the C. cladosporioides complex. The present study provides an important example of a methodology to ascertain similarity between isolates of this complex causing leaf spot in pecan trees, which should facilitate future pathogenicity studies. PMID- 27706737 TI - Association between the CDH1-472delA and -160C>A polymorphisms and diffuse and intestinal gastric cancer in a Mexican population. AB - Gastric cancer (GC), the third leading cause of cancer-related deaths in Mexico and worldwide, can be classified into diffuse (DGC) or intestinal (IGC) types based on its histological characteristics. DGC is characterized by reduced expression of the cell adhesion protein E-cadherin, which is encoded by CDH1. The -472delA (rs5030625) and -160C>A (rs16260) polymorphisms in CDH1 induce a decrease in gene transcription; in fact, these mutated alleles have been associated with GC in some populations, with conflicting results. The aim of this study was to determine the association between the CDH1 -472delA and -160C>A polymorphisms and DGC and IGC in Mexican patients. The study was conducted in 24, 23, 48, and 93 individuals with DGC and IGC, without GC (control), and belonging to the general Mexican population (GMP), respectively. The genotypes were obtained by polymerase chain reaction - restriction fragment length polymorphism and the obtained data analyzed using Arlequin 3.1. The frequencies of the mutated allele (A) of -472delA were 0.326, 0.318, 0.284, and 0.296 in the DGC, IGC, control, and GMP groups, respectively, and those of the -160C>A polymorphism were 0.174, 0.318, 0.313, and 0.280, respectively. The genotype and allele frequencies of the two polymorphisms did not differ significantly (P > 0.05) among DGC, IGC, and control subjects. Therefore, we concluded that the CDH1 -472delA and -160C>A polymorphisms are not associated with DGC or IGC in patients from western Mexico. PMID- 27706738 TI - Molecular cloning and functional characterization of cyclin E and CDK2 from Penaeus monodon. AB - Reduced reproductive performance of the black tiger shrimp (Penaeus monodon) has caused economic losses and hampered the fishing industry. Detailed investigation of the molecular mechanism by which the cell cycle is regulated in this organism is needed to understand the development and maturation of ovaries and oocytes, with a view to improving reproductive capacity. Cell cycle progression is mainly determined by cyclin-dependent kinase (CDK) and cyclin complexes, the cyclin E/CDK2 complex playing a key role in G1/S transition. However, knowledge of the interplay between cyclin E and CDK2 in invertebrates remains limited. In this study, full-length P. monodon cyclin E (Pmcyclin E) and CDK2 (PmCDK2) sequences were cloned. The open reading frame of Pmcyclin E was 1263 bp in length and encoded a 47.9-kDa protein, while that of PmCDK2 was 921 bp, encoding a protein of 34.9 kDa. Recombinant cyclin E and CDK2 proteins were expressed in Escherichia coli and purified by Ni-chelating affinity chromatography. In addition, a pull down assay was performed to identify any interaction between Pmcyclin E and PmCDK2. This research provides a basis for the study of the functional mechanisms of the cyclin E/CDK2 complex in shrimp, further enriching our knowledge of invertebrate cell cycle regulation. PMID- 27706739 TI - Polymorphisms in the DGAT1 gene in buffaloes (Bubalus bubalis) in the Amazon. AB - Water buffaloes (Bubalus bubalis) are quite well adapted to climatic conditions in the Amazon, and in this biome, they are noted for the considerable amount of meat and milk they produce and how hard they are able to work. Because of a lack of research dedicated to improving the rearing of buffaloes in the Amazon, the objective of this study was to genetically characterize the Murrah and Mediterranean breeds, as well as a mixed-breed population, based on polymorphisms in the diacylglycerol O-acyltransferase 1 gene (DGAT1), and associate the genotypes with milk production. By using the polymerase chain reaction-single strand conformation polymorphism technique, the alleles A (0.79), B (0.20), and D (0.01) were found in the Murrah breed. In the Mediterranean and mixed-breed buffaloes, we found alleles A (0.69) and (0.77) and B (0.31) and (0.23), respectively. The Murrah breed had the genotypes AA (0.63), AB (0.29), BB (0.05), and AD (0.03), and the Mediterranean and mixed-breed buffaloes had the genotypes AA (0.44) and (0.61), AB (0.50) and (0.31), and BB (0.06) and (0.08), respectively. For the Murrah, Mediterranean, and mixed-breed buffaloes, respectively, the expected heterozygosity values were 0.34, 0.43, and 0.35, the inbreeding coefficients were 0.78, -0.15, and 0.17, and the Hardy-Weinberg probabilities were 0.70, 0.67, and 0.52. The genotypes evaluated did not have an effect on milk production; however, the single nucleotide polymorphisms can be used in studies on genetic variability. PMID- 27706740 TI - An improved DNA marker technique for genetic characterization using RAMP-PCR with high-GC primers. AB - Random amplified polymorphic DNA (RAPD) is a widely used molecular marker technique. As traditional RAPD has poor reproducibility and productivity, we previously developed an improved RAPD method (termed RAMP-PCR), which increased the reproducibility, number of bands, and efficiency of studies on polymorphism. To further develop the efficiency of this method, we used high-GC content primers for improved RAMP-PCR with DNA samples from Lonicera japonica. Comparison of amplification profiles obtained by standard RAPD primers with those obtained by regular PCR and RAMP-PCR, and high-GC primers with regular PCR and RAMP-PCR showed that the average number of bands and polymorphisms per primer gradually and significantly increased (from 6.4 to 15.0 and from 4.6 to 10.2, respectively). Cluster dendrograms showed similar results, indicating that this new method is consistent and reproducible. A total of 22 samples from different species, including plants, animals, and humans, were used for RAMP-PCR with high GC primers. Multiple bands were successfully amplified from all samples, demonstrating that this method is a reliable technique with consistent results and may be of general interest in studies on different genera and species. We developed highly effective DNA markers, which can provide a more effective and potentially valuable approach than traditional RAPD for the genetic identification of various organisms, particularly of medicinal plants. PMID- 27706741 TI - Identification and characterization of genes related to cellulolytic activity in basidiomycetes. AB - Enzymes produced by basidiomycetes that are involved in the cellulose degradation process, and their respective codifying genes, must be identified to facilitate the development of novel biotechnological strategies and applications in the agro industry. The objective of this study was to identify prospective cellulase producing genes and characterize their cellulolytic activity, in order to elucidate the potential biotechnological applications (with respect to vegetal residues) of basidiomycetes. The basidiomycete strains Lentinula edodes U8-1, Lentinus crinitus U9-1, and Schizophyllum commune U6-7 were analyzed in this study. The cellulolytic activities of these fungi were evaluated based on the halo formation in carboxymethyl cellulose culture medium after dyeing with Congo red. The presence of cellulase-codifying genes (cel7A, cel6B, cel3A, and egl) in these fungal strains was also evaluated. L. edodes and S. commune presented the highest cellulolytic halo to mycelial growth radius ratio, followed by L. crinitus. Four genes were amplified in the L. edodes strain, whereas three and one genes were isolated from L. crinitus and S. commune, respectively. The cel6B gene (L. edodes) presented the conserved domain glyco_hydro_6 and characterized as cellobiohydrolase gene. The results of this study contribute to the existing knowledge on cellulases in basidiomycetes, and serve as a basis for future studies on the expression of these genes and the characterization of the catalytic activity of these enzymes. This allows for better utilization of these fungi in degrading vegetal fibers from agro-industrial residues and in other biotechnological applications. PMID- 27706742 TI - Characterization and gene cloning of the rice (Oryza sativa L.) dwarf and narrow leaf mutant dnl3. AB - The dwarf and narrow-leaf rice (Oryza sativa L.) mutant dnl3 was isolated from the Japonica cultivar Zhonghua 11 (wild-type). dnl3 exhibited pleiotropic developmental defects. The narrow-leaf phenotype resulted from a marked reduction in the number of vascular bundles, while the dwarf stature was caused by the formation of foreshortened internodes and a reduced number of parenchyma cells. The suggestion that cell division is impaired in the mutant was consistent with the transcriptional behavior of various genes associated with cell division. The mutant was less responsive to exogenously supplied gibberellic acid than the wild type, and profiling the transcription of genes involved in gibberellin synthesis and response revealed that a lesion in the mutant affected gibberellin signal transduction. The dnl3 phenotype was inherited as a single-dominant gene, mapping within a 19.1-kb region of chromosome 12, which was found to harbor three open reading frames. Resequencing the open reading frames revealed that the mutant carried an allele at one of the three genes that differed from the wild-type sequence by 2-bp deletions; this gene encoded a cellulose synthase-like D4 (CSLD4) protein. Therefore, OsCSLD4 is a candidate gene for DNL3. DNL3 was expressed in all of the rice organs tested at the heading stage, particularly in the leaves, roots, and culms. These results suggest that DNL3 plays important roles in rice leaf morphogenesis and vegetative development. PMID- 27706743 TI - Analysis of pecan cultivars Mahan and Western in East China. AB - Pecan (Carya illinoensis) has been introduced to East China for over one hundred years, but its planting is still only occurring at a small scale. The key limiting factor is its low yield. To enhance the yield pecan in East China, two pecan cultivars, Mahan and Western, were examined. Twenty traits describing phasic development, yield, nut quality, and cultural practice were investigated. We found that pecan cultivar Mahan gives a higher yield and nut quality than cultivar Western. We recommend interplanting of cultivar Pawnee to act as a pollinator tree. Appropriate cultivation practices that can be implemented to enhance fruit yield of cultivars Mahan and Western include soil-applied paclobutrazol (PBZ) at certain concentrations, pinching, and supplementary pollination. For example, the addition of 1.25 g/m2 of PBZ inhibits pecan branch growth and stimulates short bearing branches, which promotes fruit yield. We found that soil-applied PBZ reached optimal performance 82 days after application. A pinching length of 40 cm resulted in a fruit yield increase. In addition, grafting and transplantation may promote male flowering, but delays female flowering. These cultural practices may provide insights that can be used to improve pecan cultivation in East China. PMID- 27706744 TI - Novel mutations in the FUCA1 gene that cause fucosidosis. AB - Fucosidosis is a rare lysosomal storage disorder inherited in an autosomal recessive manner. Its estimated frequency is below 1 in 200,000 live births. Its clinical phenotypes include progressive neurological and mental deterioration, coarse facial features, growth retardation, visceromegaly, angiokeratomas, and seizures. The disease is caused by mutations in the FUCA1 gene that lead to deficiency of a-L-fucosidase. Here, we describe the clinical and molecular features of a Thai boy with fucosidosis. Whole exome sequencing and array-based comparative genomic hybridization analysis revealed that the patient was compound heterozygous for a single base-pair deletion (c.670delC; p.P224LfsX2) inherited from his father, and a 3281-base-pair deletion covering exon 3 inherited from his mother. Neither mutation has been reported before so the FUCA1 mutational spectrum is herein expanded. PMID- 27706745 TI - Influence of CYP2C19 on Helicobacter pylori eradication in Brazilian patients with functional dyspepsia. AB - The aim of this study was to examine the effect of polymorphisms in the cytochrome P450 (CYP) 2C19 gene (CYP2C19) on the Helicobacter pylori eradication rate in Brazilian patients with functional dyspepsia. Adults diagnosed with functional dyspepsia based on the ROME III criteria and infected with H. pylori were recruited to this study. The patients were subjected to gastrointestinal endoscopy and the H. pylori status was defined when both urease test and histopathology results were negative or positive. The patients were treated with proton pump inhibitor-based triple therapy (omeprazole, amoxicillin, and clarithromycin). CYP2C19*2 and CYP2C19*3 were genotyped by polymerase chain reaction-restriction fragment length polymorphism. One hundred and forty-eight patients (81.8% women) with a mean (+/- SD) age of 46.1 (12.2) years were included in this study. Based on the CYP2C19 genotypes, the patients were classified as homozygous extensive metabolizer (HomEM; 67.6%), heterozygous extensive metabolizer (HetEM; 26.3%), or poor metabolizer (PM; 6.1%). The H. pylori eradication rates in patients with HomEM, HetEM, and PM were 85.0, 89.7, and 100.0% (P = 0.376), respectively. The included study population comprised a high frequency of patients carrying the HomEM genotype. Although the genotypes of CYP2C19 variants were not statistically significant, the results of this study suggest a possible effect of the PM genotype on the efficacy of H. pylori eradication. PMID- 27706746 TI - Microsporogenesis analysis validates the use of artificially tetraploidized Brachiaria ruziziensis in breeding programs. AB - The genus Brachiaria contains species that have great economic importance in the Brazilian agricultural sector, as they enable cattle ranching on acid and poor soils with species that are resistant to spittlebugs and form crop-livestock forest integration systems. The genus mainly consists of tetraploid (2n = 4x = 36) and apomictic species such as B. decumbens and B. brizantha. Sexuality is found in diploid species (2n = 2x = 18) such as B. ruziziensis. Interspecific hybridization between species of interest is possible by the artificial tetraploidization of B. ruziziensis and the subsequent hybridization with genotypes of B. brizantha and B. decumbens. Therefore, tetraploidized plants have to have normal meiosis or low rates of irregularities, as well as produce viable pollen grains. The objective of this study was to compare meiosis and pollen grain viability and morphology in artificially tetraploidized B. ruziziensis with that of descendants generated from crossing and selfing. The frequency of meiotic abnormalities ranged from 4.43 to 11%, and pollen viability ranged from 61 to 85%. Abnormalities were detected from prophase I to the tetrad stage with a variable frequency between the genotypes. The meiotic behavior of the artificially tetraploidized plants was little affected, and the pollen viability of the genotypes was high. Regarding pollen grain ultrastructure, there were no variations or morphological changes in the different genotypes. The genotypes have meiotic stability and high pollen viability, and can be incorporated into Brachiaria breeding programs. PMID- 27706747 TI - Physiological analysis and transcriptome comparison of two muskmelon (Cucumis melo L.) cultivars in response to salt stress. AB - Melon (Cucumis melo L.) is an important vegetable crop that ranks second in salt tolerance among the Cucurbitaceae. Previous studies on the two muskmelon cultivars 'Bing XueCui' (BXC) and 'Yu Lu' (YL) revealed that they had different characteristics under salt stress, but the molecular basis underlying their different physiological responses is unclear. Here, we combined a physiological study with a genome-wide transcriptome analysis to understand the molecular basis of genetic variation that responds to salt stress in the melon. BXC performed better under salt stress than YL in terms of biomass and photosynthetic characteristics, because it exhibited less reduction in transpiration rate, net photosynthesis rate, and stomatal conductance under 150-mM NaCl stress than YL. A transcriptome comparison of the leaves of the cultivars revealed that 1171 genes responded to salt stress in BXC while 1487 genes were identified as salt-stress responsive in YL. A real-time polymerase chain reaction analysis of 12 of the responsive genes revealed that there was a strong, positive correlation with RNA sequencing data. The genes were involved in several pathways, including photosynthesis, the biosynthesis of secondary metabolites, metabolism, and plant hormone signal transduction, and their expression levels differed between the two cultivars in response to salt stress. This study provides a molecular perspective of two melon cultivars in response to salt stress, and its results could be used to investigate the complex molecular mechanisms underlying salt tolerance in the melon. PMID- 27706748 TI - Classification and phylogenetic analysis of Chinese hawthorn assessed by plant and pollen morphology. AB - The Chinese hawthorn (Crataegus pinnatifida Bge. var. major N.E.Br.) is uniquely originated in northern China. The ecological and horticultural importance of Chinese hawthorn is considerable and some varieties are valued for their fruit or medicine extracts. Its taxonomy and phylogeny remain poorly understood. Apart from general plant morphological traits, pollen is an important trait for the classification of plants and their evolutionary origin. However, few studies have investigated the pollen of Chinese hawthorn. Here, an analysis of plant and pollen morphological characteristics was conducted in 57 cultivars from the Shenyang region. Thirty plant morphological characters and nine pollen grain characters were investigated. The plant morphological analysis revealed that the coefficient of variation for 13 traits was >20%, which indicates a high degree of variability. We also found that the pollen grains varied greatly in size, shape (from prolate to perprolate), and exine pattern (striate-perforate predominantly). The number of apertures was typically three. Based on these findings, we suggest that pollen morphology associated with plant morphological traits can be used for classification and phylogenetic analysis of Chinese hawthorn cultivars. In sum, our results provide new insights and constitute a scientific basis for future studies on the classification and evolution of Chinese hawthorn. PMID- 27706750 TI - Single base substitution causing the fragrant phenotype and development of a type specific marker in aromatic coconut (Cocos nucifera). AB - The fragrance gene, betaine aldehyde dehydrogenase 2 (Badh2), has been well studied in many plant species. The objectives of this study were to clone Badh2 and compare the sequences between aromatic and non-aromatic coconuts. The complete coding region was cloned from cDNA of both aromatic and non-aromatic coconuts. The nucleotide sequences were highly homologous to Badh2 genes of other plants. Badh2 consisted of a 1512-bp open reading frame encoding 503 amino acids. A single nucleotide difference between aromatic and non-aromatic coconuts resulted in the conversion of alanine (non-aromatic) to proline (aromatic) at position 442, which was the substrate binding site of BADH2. The ring side chain of proline could destabilize the structure leading to a non-functional enzyme. Badh2 genomic DNA was cloned from exon 1 to 4, and from exon 5 to 15 from the two coconut types, except for intron 4 that was very long. The intron sequences of the two coconut groups were highly homologous. No differences in Badh2 expression were found among the tissues of aromatic coconut or between aromatic and non aromatic coconuts. The amino acid sequences of BADH2 from coconut and other plants were compared and the genetic relationship was analyzed using MEGA 7.0. The phylogenetic tree reconstructed by the Bayesian information criterion consisted of two distinct groups of monocots and dicots. Among the monocots, coconut (Cocos nucifera) and oil palm (Elaeis guineensis) were the most closely related species. A marker for coconut differentiation was developed from one-base substitution site and could be successfully used. PMID- 27706749 TI - Case Report Identification of a novel SLC45A2 mutation in albinism by targeted next-generation sequencing. AB - Albinism is a diverse group of hypopigmentary disorders caused by multiple genetic defects. The genetic diagnosis of patients affected with albinism by Sanger sequencing is often complex, expensive, and time-consuming. In this study, we performed targeted next-generation sequencing to screen for 16 genes in a patient with albinism, and identified 21 genetic variants, including 19 known single nucleotide polymorphisms, one novel missense mutation (c.1456 G>A), and one disease-causing mutation (c.478 G>C). The novel mutation was not observed in 100 controls, and was predicted to be a damaging mutation by SIFT and Polyphen. Thus, we identified a novel mutation in SLC45A2 in a Chinese family, expanding the mutational spectrum of albinism. Our results also demonstrate that targeted next-generation sequencing is an effective genetic test for albinism. PMID- 27706751 TI - Association between peptidyl arginine deiminase 4 (PADI4)-104C/T polymorphism and rheumatoid arthritis: a meta-analysis in the Chinese population. AB - The correlation between the -104C/T polymorphism in the peptidyl arginine deiminase 4 (PADI4) gene and rheumatoid arthritis (RA) risk has been analyzed in several studies. However, the results are inconclusive and remain to be confirmed in several ethnic groups. The effect of the PADI4-104C/T polymorphism on RA risk in the Chinese population was evaluated in a meta-analysis. Studies with dates of publication up to July 2015 conforming to the inclusion criteria were retrieved from PubMed and Chinese databases. The associations were assessed with pooled odds ratios (ORs) and 95% confidence intervals (CIs). Ten studies, including 2119 RA cases and 1962 controls, that conformed to the study criteria were included in this analysis. The overall analysis indicated a significant association between the PADI4-104C/T polymorphism and RA risk in the Chinese population (T vs C: OR = 1.45, 95%CI = 1.18-1.78; TT vs CC: OR = 1.49, 95%CI = 1.24-1.80; TT vs CC+CT: OR = 1.28, 95%CI = 1.08-1.51; TT+CT vs CC: OR = 1.75, 95%CI = 1.30-2.37). Analysis of data stratified by the geographic area and source of controls revealed that the PADI4-104C/T polymorphism was significantly associated with RA risk in a North Chinese population. In conclusion, the results of this meta-analysis indicated that the PADI4-104C/T variants could influence the risk of RA in the Chinese population; further studies in other ethnic groups are required to draw definite conclusions. PMID- 27706753 TI - Identification of SNPs in growth-related genes in Colombian creole cattle. AB - Colombian creole cattle have important adaptation traits related to heat tolerance and reproductive and productive efficiency. Romosinuano (ROMO) and Blanco Orejinegro (BON) are the most common breeds used by Colombian cattle breeders. Growth traits are of prime importance in these animals, which are mainly raised for beef production. Genes encoding growth hormone, growth hormone receptor, homeobox protein, insulin growth factor binding protein 3, leptin, and myostatin have been associated with physiological growth pathways in cattle and other species. We therefore aimed to identify single nucleotide polymorphisms (SNPs) within these genes in ROMO, BON, and Zebu cattle. DNA regions of these genes were sequenced in 386 animals; 47 new SNPs were found, of which 14 were located in the exonic regions, thereby changing the protein sequence. An association of SNPs with weaning weight (WW), daily weight gain at weaning (DWG), and weight at 16 months (W16M) traits was deduced. The genetic analysis revealed several SNPs related to these traits. The SNP GhRE06.2 had a significant association with WW and the SNP Lep03.4 was highly associated with DWG and W16M. Other polymorphisms were significantly associated with WW and DWG, although they did not surpass the Bonferroni significance threshold. The new mutations identified may indicate important points of genetic control in the DNA that could be responsible for changes in the expression of the analyzed traits. These SNPs might be used in future breeding programs to improve the productive performance of cattle in beef farms. PMID- 27706752 TI - Biometric analysis of arabica coffee grown in low potassium nutrient solution under greenhouse conditions. AB - Genetic parameters and associations between morpho-agronomic traits and nutritional efficiencies of arabica coffee cultivars were estimated to identify promising traits to assist in the selection of coffee genotypes efficient in potassium use, under limiting conditions of this nutrient. The experiment was conducted in a greenhouse with 20 arabica coffee cultivars grown in nutrient solution with a low potassium level (1.5 mM), using a randomized block design with three replicates. The traits evaluated were plant height, number of leaves, number of nodes, internode length, stem diameter, leaf area, rooting efficiency, potassium absorption efficiency, potassium translocation efficiency, biomass production efficiency, and potassium use efficiency. Genetic variability among coffee cultivars for all the evaluated traits was found. The phenotypic variance for all traits showed a higher contribution of genetic variance compared to environmental variance. Plant height, internode length, stem diameter, leaf area, biomass production efficiency, and potassium use efficiency had a genotypic determination coefficient (H2) above 80% and variation index greater than one. Leaf area and stem diameter had significant and positive genetic correlations with rooting, biomass production, and potassium use efficiencies. Stem diameter has great potential for use in breeding programs with a goal of indirect selection of cultivars that have greater potassium use efficiency in environments with restrictions of this nutrient. PMID- 27706754 TI - Development of the first polymorphic microsatellite markers for the Roman snail Helix pomatia L., 1758 (Helicidae) and cross-species amplification within the genus Helix. AB - The terrestrial snail Helix pomatia (Gastropoda: Stylommatophora: Helicidae) is one of the largest gastropod species in Europe. This species is strictly protected in some European Union countries; however, at the same time, it is also farmed and commercialized for human consumption. Here, we describe 11 microsatellite markers that are very useful in population genetic studies for assessing the status of both wild and farmed populations of this species of community interest. The microsatellites were isolated using 454 pyrosequencing technologies and 11 primer pairs were selected and used for genotyping an H. pomatia population and also checked for cross-species amplification on H. lucorum and H. lutescens specimens. The number of alleles per locus ranged from 3 to 13 and observed heterozygosity was between 0.458 and 0.917. Seven of these loci were polymorphic in H. lucorum, and four in H. lutescens. This set of nuclear markers provides a powerful tool for population genetic studies of this species of community interest, and also for closely related species. The described microsatellite markers should also facilitate the identification of populations of conservation concern. PMID- 27706755 TI - RNA applications for endophytic research. AB - Endophytic microorganisms, mainly bacteria and fungi, have intrinsic relationships with the host plants, involving complex chemical and genetic communication networks. The relationship among these organisms involves the development of regulatory mechanisms of gene expression that control their development and response to different interactions. Although RNA molecules are already being used in studies of microorganism diversity and taxonomy, for example, using comparisons of rRNA regions, they may also be useful tools in the exploration of gene regulation and modeling of other molecules, such as the analysis of microRNA and small interfering RNAs. Transcriptional profile analyses are capable of providing robust information on biosynthetic pathways, genes involved in the interaction and differential production of metabolites by endophytes, using RNA-seq approaches. In-depth studies of RNA types and their functions in endophytes may provide valuable information that can be used for biotechnological manipulation of microorganisms to produce metabolites, bioremediation, biological control of pathogens, and decrease plant diseases, among other economically important applications. Our study highlights the present state of knowledge of studies involving endophytes, RNA molecules, and future perspectives. PMID- 27706756 TI - Molecular phylogeny of the Bactrian camel based on mitochondrial Cytochrome b gene sequences. AB - The Bactrian camel is an important domesticated animal providing milk, meat, and other products in desert countries. In this study, 111 individuals representing 11 domestic Bactrian camel breeds from China, Mongolia, Russia, and one wild Bactrian camel group from Mongolia were selected for the preparation of mitochondrial DNA. The 1140-bp fragments of the cytochrome b gene (Cytb) were amplified by polymerase chain reaction and sequenced directly. Sequences of the 92 domestic and 19 wild Bactrian camel samples were analyzed with DNASTAR, and a phylogenic tree was constructed using MEGA. The analysis revealed sixteen haplotypes among the samples that were divided into two haplogroups: a domestic haplogroup (H1-H13, H15, and H16) and a wild haplogroup (H14). Haplotype diversity values were from 0.356 in the HosZogdort, to 0.889 in the Sunit Bactrian camel breed. The Sunit breed displayed the highest nucleotide diversity value (0.00115), and the HosZogdort breed had the lowest value (0.00031). All domestic Bactrian camels formed a single monophyletic lineage that is the sister group to wild Bactrian camels, a finding consistent with a single domestication event and independent maternal inheritance since domestication. In addition, the most common mitochondrial haplotypes (H1, H3, and H4) were shared between Chinese, Mongolian, and Russian domestic Bactrian camels, which indicated that there was no distinguishing geographic structure among the domestic breeds from these three regions. These findings provide important insights into patterns of relatedness among Bactrian camels from the Chinese, Mongolian, and Russian regions. PMID- 27706758 TI - JNK pathway and relative transcriptional factor were involved in ginsenoside Rh2 mediated G1 growth arrest and apoptosis in human lung adenocarcinoma A549 cells. AB - Ginsenoside Rh2 has been shown to have an anti-tumor effect on a wide range of cancers. A previous study has shown that ginsenoside Rh2 can inhibit the proliferation of the human lung adenocarcinoma A549 cell line in a dose-dependent manner by activating caspase-8/3 activity to promote apoptosis. However, the association of the JNK signaling pathways and transcription factors with ginsenoside Rh2 in the suppression of non-small cell lung cancer has not yet been reported. In this study, we found that ginsenoside Rh2 can activate the JNK/MAPKs signaling pathway and increase the phosphorylation and transcriptional activity of the transcription factors AP-1 and ATF2. Ginsenoside Rh2 also reduced the expression of transcription factors E2F1 and c-Myc. Furthermore, ginsenoside Rh2 affected the expression levels of cyclin D1 and the CDK4 protein, which are key regulatory factors of the G1/S cyclin-dependent kinase. The anti-proliferative and induced apoptotic effects of ginsenoside Rh2 on A549 cell provide evidence to support the application of traditional Chinese medicine to lung cancer treatment. PMID- 27706757 TI - Cardiac damage and dysfunction in diabetic cardiomyopathy are ameliorated by Grx1. AB - Glutaredoxin 1 (Grx1) has been found to be an important endogenous antioxidant enzyme closely related to the pathogenesis of diabetes and cardiovascular diseases caused by oxidative stress. In this study, the functional changes of the Grx1 redox system in blood of hyperglycemic patients were examined. Furthermore, using a rat model of streptozotocin (STZ)- and high-fat-diet-induced type 2 diabetes, we explored the correlation between functional changes of the Grx1 redox system in the left ventricular tissue and blood of the diabetic rats. Moreover, we studied the protective effect of Grx1 against cardiac toxicity caused by the high-glucose-induced expression of cardiac matrix metalloproteinases (MMPs) in primary cultured cardiac fibroblasts. Finally, we investigated the protective effects and signaling regulatory mechanism of Grx1 against diabetic cardiomyopathy (DCM) in terms of oxidative stress and NF-kB mediated fibrosis-associated signaling pathways. In the serum of hyperglycemic patients, Grx1 levels were elevated, total/protein thiol or sulfhydryl (Total SH/P-SH) levels were decreased, glutathione was downregulated, and oxidized glutathione was upregulated. In addition, in the left ventricular myocardium and blood of the diabetic rats, Grx1 levels were significantly increased and glutathione reductase and P-SH levels were decreased. Moreover, endogenous Grx1 was highly expressed in cardiac fibroblasts during high-glucose treatment, and exogenous Grx1 can prevent DCM by controlling oxidative damage and MMP expression. These findings are suggestive of changes in the Grx1 redox system, and Grx1-regulated protein oxidative modifications may serve as molecular markers for diabetes caused by high-glucose-induced oxidative stress. PMID- 27706759 TI - In vitro inhibition of invasion and metastasis in colon cancer cells by TanIIA. AB - The purpose of this study was to investigate the effect of the traditional Chinese medicine TanIIA on the viability, invasion, and metastasis of SW480 cells. SW480 cells were treated with TanIIA for 24 h, and MTT assays were performed to determine the effect of TanIIA on cell viability. Transwell transmembrane experiments were applied to test the effect of 1.0 mg/mL TanIIA on SW480 cell invasion and metastasis abilities. Western blotting was performed to determine the expression of the tumor cell metastasis proteins E-cadherin, vimentin, and MMP-9. The cell growth inhibition rates were 0%, 26 +/- 4.3%, 43.47 +/- 4.0%, 63.0 +/- 5.5%, and 76.8 +/- 7.8% for treatment with 0, 0.5, 1.0, 2.0, and 5.0 mg/L TanIIA, respectively. The differences in the cell viability inhibitory rates among all groups were statistically significant (P < 0.05). The Transwell assay results indicated that SW620 cell invasion and metastasis abilities were strongly inhibited by 1.0 mg/mL TanII. The western blotting results showed that the expression of E-cadherin was significantly increased and that the expression levels of vimentin and MMP-9 were significantly decreased after treatment with 1.0 mg/mL TanII for 24 h (P < 0.05). Tan II can effectively inhibit the biological activity of colon cancer in vitro and prevent the invasion of colon cancer cells. PMID- 27706760 TI - Inbreeding depression in single, three way and double-cross hybrids of maize. AB - Currently, one of the acclaimed alternatives for increasing maize yield is accomplished through utilization of heterosis in hybrid cultivars. However, upon performing crosses between related pairs, there are losses due to inbreeding depression. Thus, the aim of this study was to estimate inbreeding depression and the contribution of loci in heterozygosity in different types of maize hybrids. Eight treatments were evaluated, considering the F1 and S0 generations of four commercial hybrids. A randomized block experimental design was used, with three replications, and plots consisting of two three-meter long rows at a spacing of 0.50 m. The traits evaluated were plant height, first ear height and husked ear weight. For ear weight trait, there was a significant difference, where the treatments could be classified into three distinct groups. In this case, the single-cross hybrids AG7088 and 30F90Y exhibited greater depression through inbreeding due to the greater contribution of loci in heterozygosity and consequent predominance of deviations due to dominance. PMID- 27706762 TI - Genomic characterization and phylogenetic analysis of Chinese sacbrood virus isolated from Loess Plateau, China. AB - The complete genomic RNA of the Chinese sacbrood virus (CSBV) strain, which infects the honeybees in the Loess plateau, was sequenced and analyzed. The CSBV SX strain contains 8705 nucleotides, which includes a single large open reading frame (99-8681 nucleotides) encoding 2860 amino acids. A novel efficient identification method was used to investigate the samples infected by CSBV. The putative amino acid sequence alignment analysis showed that, except for some normal well characterized domains such as RNA helicase, RNA protease, and RNA dependent RNA polymerase domains, a calicivirus coat protein domain was identified at amino acids 493-564. Phylogenetic analysis indicated that CSBV-SX was closely related to CSBV-BJ, and this result was supported by nucleotide multiple sequence alignment and protein multiple sequence alignment analysis results. These differences in the CSBV-SX strain may be related to virus adaptation to the xerothermic, low relative humidity, and strong ultraviolet radiation conditions in the Loess Plateau. PMID- 27706761 TI - Correlation of acetabular chondrocyte apoptosis with caspase-3 and Bcl-2 expression in developmental dislocations of the hip. AB - This study aimed to determine whether abnormal apoptosis is present in acetabular cartilage in early developmental dislocations of the hip (DDH), and if so, whether it is correlated with the expression of caspase-3 and Bcl-2. DDH was induced in 24 4-week-old New Zealand white rabbits. Acetabular cartilage specimens from the experimental and control groups were stained with hematoxylin and eosin (H&E). Animals from the experimental group developed acetabular dysplasia. Apoptotic chondrocytes were observed by ultrastructural electron microscopy and H&E. TUNEL assays revealed significantly greater acetabular chondrocyte apoptosis in the treated samples as compared to the control. Significantly higher caspase-3 expression and lower Bcl-2 expression were also measured in the DDH group compared with the control. We conclude that excessive apoptosis does occur in acetabular cartilage with DDH, and is positively correlated with high caspase-3 expression as well as low Bcl-2 expression. PMID- 27706763 TI - Role of GSTM1, GSTT1, and GSTP1 IIe105Val gene polymorphisms in the response to chemotherapy and overall survival of advanced non-small cell lung cancer. AB - We evaluated the association between GSTM1, GSTT1, and GSTP1 IIe105Val gene polymorphisms and treatment outcomes of advanced non-small cell lung carcinoma. Between January 2010 and December 2012, a total of 244 patients with non-small cell lung carcinoma were recruited from Yiwu Central Hospital. The GSTM1, GSTT1, and GSTP1 IIe105Val gene polymorphisms were analyzed by polymerase chain reaction restriction fragment length polymorphism and the results were statistically analyzed. Conditional regression analysis, showed that individuals carrying the null GSTM1 were associated with an increased risk of response to chemotherapy when compared to the present GSTM1 (odds ratio = 1.88, 95% confidence interval (CI) = 1.01-3.47). Moreover, the GG genotype of GSTP1 IIe105Val was associated with a better response to chemotherapy compared to the AA genotype (odds ratio = 2.77, 95%CI = 1.14-6.64). The null GSTM1 genotype was associated with a lower risk of death from all causes when compared with the present GSTM1 genotype (hazard ratio = 2.16, 95%CI = 1.10-4.38). Moreover, the GG genotype of GSTP1 IIe105Val was correlated with a reduced risk of death from all causes compared with the AA genotype (hazard ratio = 2.94, 95%CI = 1.11-8.68). In conclusion, we found that the null GSTM1 and the GG genotype of GSTP1 IIe105Val were correlated with a good response to chemotherapy and improved overall survival of advanced non-small cell lung carcinoma patients. PMID- 27706764 TI - Genetic diversity of Lippia sidoides Cham. and L. gracilis Schauer germplasm. AB - The conservation of plants in germplasm banks ensures the characterization and availability of these resources for future generations. The present study used DNA markers to obtain genetic information about germplasm collections of Lippia sidoides and L. gracilis, which are maintained in an Active Germplasm Bank (AGB). Genetic variability of samples in the AGB was assessed using 12 combinations of amplified fragment length polymorphism (AFLP) primers (EcoRI/MseI). Twenty simple sequence repeat primers designed for L. alba were tested to determine their transferability in L. sidoides and L. gracilis. The AFLP markers generated 789 markers. The assessed loci exhibited a moderate Shannon diversity index (I = 0.42) in both species, suggesting that the conserved accessions possess an intermediate level of genetic diversity. Twelve microsatellite loci amplified satisfactorily, and nine loci were polymorphic in each species. A total of 23, 22, and 36 alleles, with an average of 2.5, 2.4, and 3.27 alleles per locus were identified for L. sidoides and L. gracilis accessions in the AGB, and Lippia sp sampled plants, respectively. Analyses of genetic structure permitted the identification of three different groups using both sets of markers, of which two were representative of L. sidoides. The information generated in this study may help to create, expand, and maintain collections of these species and may assist in genetic-breeding programs. PMID- 27706766 TI - Transformation of the CmACS-7 gene into melon (Cucumis melo L.) using the pollen tube pathway. AB - The aim of the present study was to develop a transformation system that may be useful for introducing agronomically and biotechnologically relevant traits into melon. The production of transplanted melon with maternal inheritance of the transgene could solve problems related to outcrossing between genetically modified crops and conventional crops or their wild relatives. By analyzing the main influencing factors systematically, the pollination time was ascertained and the pollen-tube pathway genetic transformation system was optimized. A screening system for resistant seeds from the T1 generation was established. The transformed seedlings were grown under standard field conditions and selected using a polymerase chain reaction-based analysis. The resistant plants were detected at a rate of 5%. These results indicate that enhanced production hastens the initiation of bisexual flowers, development of mature bisexual flowers, and fruit set in melon. We have established a melon transformation system based on the pollen-tube method. PMID- 27706765 TI - Role of IL-10 and TNF-alpha during Mycobacterium tuberculosis infection in murine alveolar macrophages. AB - Mycobacterium tuberculosis (Mtb) is known to be responsible for tuberculosis (TB), but the pathogenesis of this disease and the host defense mechanisms involved are, for the most part, poorly understood. In this study, we divided 30 male C57BL/6 mice into control and infection groups, and following injection with physiological saline or Mtb, respectively, euthanized five mice from each group on days 1, 3, and 7. TNF-alpha and IL-10 levels were measured by enzyme-linked immunosorbent assay and flow cytometry, with the latter also being performed to assess apoptosis rates. Protein expression of STAT3 and its phosphorylated form (p-STAT3) was analyzed by western blotting. After Mtb infection, TNF-alpha and IL 10 levels, alveolar macrophage apoptosis, and STAT3 and p-STAT3 expression increased significantly on days 1, 3, and 7 (P < 0.05), with maximum values on day 3. Furthermore, the Pearson correlation test showed that production of the cytokines TNF-alpha and IL-10 correlated strongly with expression of STAT3 and p STAT3 proteins (P < 0.05). Taken together, our results suggest that the STAT3 signaling pathway might play a key role in the regulation of cell proliferation and alveolar macrophage apoptosis in response to Mtb. This provides a theoretical mechanism behind TB pathogenesis and host defense against Mtb, and contributes towards development of an effective treatment. PMID- 27706767 TI - Bioinformatic analyses of GRAS genes in Betula kirghisorum based on transcriptome data. AB - The transcriptomes of salt-stressed and unstressed Betula kirghisorum plants were analyzed using high throughput sequencing technology. A total of 52,239,804 and 51,772,998 clean reads were obtained from the two libraries, respectively, and de novo assembled into 60,545 all-unigenes. A total of 39,997 unigenes were annotated using public databases. Overall, 7206 genes were differentially expressed in unigenes and were involved in 127 pathways. Thirteen transcription factor families were identified in B. kirghisorum, including GRAS proteins, which are plant-specific transcription factors. By using bioinformatic methods to predict and analyze physicochemical properties, structural data were obtained on the 19 potential GRAS proteins. The results revealed that these proteins are hydrophilic, with significant differences in their length and molecular weight. The main secondary structures were alpha helices and random coils. BkGRAS proteins possess typical GRAS domains: LHR I; VHIID motif; LHR II; PFYRE motif; and SAW motif. In the majority of BkGRAS proteins, AGG, AGA, UCU, GCU, GGG, CCA, GUU, GUG, AUU, GAU, and AAG codons were used preferentially. Aside from the BkGRAS17 gene (relative synonymous codon usage (RSCU) = 1.20), usage of the UUA codon by other BkGRAS genes was low (RSCU < 1.0). The effective number of codons showed that BkGRAS genes have low codon bias. Subcellular localization analysis that predicted these proteins are found in the nucleus, cytoplasm, or chloroplast. BkGRAS proteins were divided into six subfamilies: SCR, LISCL, SCL3, DELLA, HAM, and PAT1. These results provide important information for the further functional study of GRAS genes in B. kirghisorum. PMID- 27706768 TI - Effects of sacral nerve stimulation with acupuncture on gut transit time and c kit expression in colon of rats with slow transit constipation. AB - Sacral nerve stimulation (SNS) is an alternative surgical approach to alleviate fecal incontinence and constipation. This study aimed to explore the effects and underlying mechanisms of SNS with acupuncture on gut transit time and colon c-kit protein expression in rats with slow transit constipation (STC). Fifty Sprague Dawley rats were randomly divided into five groups: blank control, SNS, Mosapride, sham SNS, and STC model control group. The STC model was established by subcutaneous injection of morphine. Each group was treated over a 15-day period. Gut transit time was measured 1 day before the treatment started and after 5, 10, and 15 days of treatment. After the 15-day treatment, animals were sacrificed and colonic tissues were collected for analysis of c-kit protein expression, using western blot analysis. We found significant differences in gut transit time in the SNS group compared with the Mosapride group after 5 (P = 0.001) and 10 (P = 0.004) days of treatment. After 15 days of treatment, there were no differences in gut transit time among the SNS, Mosapride, and blank control groups. However, significant differences were observed when comparing the SNS and Mosapride groups with the STC model and sham SNS groups. A decreased c kit protein expression was observed in the STC model control, sham SNS, and Mosapride groups, compared with the SNS group (P = 0.001). Our data indicate that SNS can decrease gut transit time and increase the expression of c-kit protein in rats with STC to improve colon transit function. PMID- 27706769 TI - Characterization of RsMYB28 and RsMYB29 transcription factor genes in radish (Raphanus sativus L.). AB - Glucosinolates (GSLs) are important secondary metabolites in Brassicaceae plants. Previous studies have mainly focused on GSL contents, types, and biosynthesis related genes, but the molecular characterization patterns of GSL biosynthesis related transcription factors remain largely unexplored in radish (Raphanus sativus L.). To isolate transcription factor genes regulating the GSL biosynthesis, genomic DNA and cDNA sequences of RsMYB28 and RsMYB29 genes were isolated in radish. Two R2R3-MYB domains were identified in the deduced amino acid sequences. Subcellular localization and yeast-one hybrid assays indicated that both the RsMYB28 and RsMYB29 genes were located in the nucleus and possessed transactivation activity. Reverse transcription quantitative analysis showed that the RsMYB28 and RsMYB29 genes were expressed in seeds, leaves, stems, and roots at the seedling, taproot thickening, and mature stages. Both genes were highly expressed during the seedling and taproot thickening stages. The expression level of RsMYB28 was found to be up-regulated following wounding, glucose, and abscisic acid treatments, whereas RsMYB29 was up-regulated following wounding and methyl jasmonate treatments. These results provide insights into the biological function and characterization of the RsMYB28 and RsMYB29 genes, and facilitate further dissection of the molecular regulatory mechanism underlying the GSL biosynthesis in radish. PMID- 27706770 TI - Activation of p38-mitogen-activated protein kinase contributes to ischemia reperfusion in rat brain. AB - Inflammation plays an important role in cerebral ischemia reperfusion, which can cause severe damage to the brain and may lead to cerebral hemorrhage transformation. p38-mitogen-activated protein kinase (p38mapk) has been implicated in the etiology of a number of diseases because it is a cause of inflammation, but comparatively little research has been carried out into its role in the etiology of ischemia reperfusion. We investigated the expression of p38mapk in cerebral ischemia reperfusion to gain a better understanding of its potential role in hemorrhagic transformation (HT). One hundred rats were randomly divided into three groups: an ischemia reperfusion group, an ischemia group, and a sham-operated group. We carried out neurological deficit assessments, infarct volume measurements, histopathological examinations, and immunohistochemistry analyses. p38mapk was overexpressed in the ischemia reperfusion group, which exhibited severe tissue damage and greater edema than the other two groups. These results suggest that p38mapk plays an important role in cerebral ischemia reperfusion, and may be one of the causes of HT. PMID- 27706771 TI - Detection of aneuploidies in spontaneous abortions by quantitative fluorescent PCR with short tandem repeat markers: a retrospective study. AB - Approximately 10-15% of all pregnancies end in spontaneous abortions. Many factors can lead to embryonic loss; however, it has been well established that over 50% of all miscarriages result from chromosomal abnormalities, primarily aneuploidies (>96%). Identifying the cause of miscarriage can significantly reduce the psychological stress in women, and enable better genetic counseling for a future pregnancy. Quantitative fluorescent polymerase chain reaction (QF PCR) has been previously used in the study of chromosomal abnormalities. In this retrospective study, the frequency of aneuploidy in samples of 130 miscarriages undergone by patients (age average: 34.1 +/- 4.6 years) at our institution was determined by QF-PCR using short tandem repeat markers. The gender of the miscarriage cases was determined by amplifying the amelogenin locus (70 males and 60 females). Seventy-one of these cases (54.6%) presented aneuploidies such as trisomy, monosomy, triploidy, and double trisomy. Trisomy 22 was the most common aneuploidy (present in 14 cases), followed by trisomy 15, trisomy 16, and monosomy X. We also observed monosomy at chromosomes X and 21 and a case with multiple aneuploidies at chromosomes 16 and 22. The most common aneuploidies associated with miscarriages were detected by QF-PCR; therefore, we concluded that QF-PCR is a rapid and reliable method for the detection of aneuploidy, and can be used as an accessory to the widely used karyotype analysis. PMID- 27706772 TI - In silico identification and characterization of the WRKY gene superfamily in pepper (Capsicum annuum L.). AB - The WRKY family is one of the most important transcription factor families in plants, involved in the regulation of a broad range of biological roles. The recent releases of whole-genome sequences of pepper (Capsicum annuum L.) allow us to perform a genome-wide identification and characterization of the WRKY family. In this study, 61 CaWRKY proteins were identified in the pepper genome. Based on protein structural and phylogenetic analyses, these proteins were classified into four main groups (I, II, III, and NG), and Group II was further divided into five subgroups (IIa to IIe). Chromosome mapping analysis indicated that CaWRKY genes are distributed across all 12 chromosomes, although the location of four CaWRKYs (CaWRKY58-CaWRKY61) could not be identified. Two pairs of CaWRKYs located on chromosome 01 appear to be tandem duplications. Furthermore, the phylogenetic tree showed a close evolutionary relationship of WRKYs in three species from Solanaceae. In conclusion, this comprehensive analysis of CaWRKYs will provide rich resources for further functional studies in pepper. PMID- 27706773 TI - Relationship between genetic polymorphisms of methylenetetrahydrofolate reductase and breast cancer chemotherapy response. AB - Activity of methylenetetrahydrofolate reductase (MTHFR), an enzyme involved in folate metabolism, is influenced by mutations in the corresponding gene, contributing to a decrease in 5,10-MTHF. Due to such polymorphisms, individuals differ in MTHFR enzyme activity and plasma folate levels. We investigated the relationship between two common MTHFR polymorphisms (C677T and A1298C) and breast cancer (BC) chemotherapy response. From February 2013 to January 2016, 148 advanced BC patients at the Center Hospital of Cangzhou were enrolled and treated with six different chemotherapy regimens. Subjects were genotyped using polymerase chain reaction-restriction fragment length polymorphism. Forty-one (27.7%), 70 (47.3%), and 37 (25.0%) patients carried the C/C, C/T, and T/T C677T genotypes, respectively; 101 (68.2%), 42 (28.4%), and 5 (3.4%) had the A/A, A/C, and C/C genotypes of A1298C, respectively. Total chemotherapy efficacy was 66.9% (99/148), with 7 (4.7%), 92 (62.2%), 36 (24.3%), and 13 (8.8%) cases showing complete response, partial response, no change, and progressive disease, respectively. Chemotherapy regimens did not differ in effectiveness (P > 0.05). Efficacy rates associated with C677T C/C, C/T, and T/T genotypes were 58.5, 58.6, and 91.9%, respectively, with T/T carriers exhibiting significantly better responses than the C/C (P < 0.05) and C/T groups (P < 0.05). Effectiveness among A1298C A/A, A/C, and C/C carriers was 70.6, 64.3, and 0.0%, respectively, but no difference was established between these genotypes in this regard (P > 0.05). The MTHFR C677T genotype may be associated with BC chemotherapy response, and could be of great value in guiding individualized treatment for this disease. PMID- 27706774 TI - Effect of miRNA-203 on cervical cancer cells and its underlying mechanism. AB - miRNA-203 is involved in the development and progression of various types of cancer. However, its role in cervical cancer remains unclear. The aim of this study was to investigate the effect of miRNA-203 on the proliferation and migration of HeLa cervical cancer cells, as well as survivin expression in these cells. A miRNA-203 primer probe was designed according to a sequence obtained from NCBI. The expression of miRNA-203 in cervical epithelial cells and cervical cancer cells was detected by quantitative reverse transcriptase-polymerase chain reaction. The miRNA-203 expression pattern was compared between these two cell lines. The cervical cancer cells were transfected with miRNA-203 mimic or inhibitor to determine their effects on proliferation and migration. The expression of the miRNA-203 target protein (survivin) was analyzed by western blot. Cervical cancer cells showed reduced miRNA-203 expression compared to cervical epithelial cells. Transfection of miRNA-203 mimic upregulated the expression of miRNA-203, suppressed cell proliferation and migration, and downregulated survivin expression (P < 0.05). However, downregulation of miRNA 203 expression did not affect proliferation, migration, and survivin expression in cervical cancer cells (P > 0.05). In conclusion, upregulation of miRNA-203 in cervical cancer cells inhibits the proliferative and migratory capacities of these cells by downregulating the expression of survivin. PMID- 27706775 TI - Association of ADH1B Arg47His and ALDH2 Glu487Lys polymorphisms with risk of colorectal cancer and their interaction with environmental factors in a Chinese population. AB - Human colorectal cancer (CRC) is a major worldwide health concern, and its development has been shown to be associated with alcohol intake. We carried out a study to investigate the effect of the ADH1B Arg47His and ALDH2 Glu487Lys genetic polymorphisms and their interaction with alcohol consumption on development of CRC. Between March 2013 and May 2015, a total of 274 CRC patients and 358 healthy controls were recruited. Genotyping of sequence variations was performed using the polymerase chain reaction-restriction fragment length polymorphism method. Under a co-dominant model, individuals with the ADH1B Arg47His AA genotype showed increased CRC risk compared to those carrying the GG genotype, with an adjusted odds ratio (and 95% confidence interval) of 3.37 (2.00-5.70). Moreover, under dominant and recessive models, ADH1B Arg47His variant genotypes were associated with greater susceptibility to CRC when compared with the wild-type sequence. Both polymorphisms examined were positively associated with alcohol consumption in a Spearman correlation analysis of CRC risk. In conclusion, our study suggests that the ADH1B Arg47His polymorphism, but not the ALDH2 Glu487Lys variation, may influence development of CRC in the Chinese population. PMID- 27706776 TI - Development, characterization, and annotation of potential simple sequence repeats by transcriptome sequencing in pears (Pyrus pyrifolia Nakai). AB - Simple sequence repeats (SSRs), one of the most powerful molecular markers, can be used for DNA fingerprinting, variety identification, genetic mapping, and marker-assisted selection. Using the pear's (Pyrus pyrifolia Nakai) 75,764 unigenes (55,676,271 bp) obtained by deep transcriptome sequencing, a total of 10,622 novel SSRs were identified in 9154 unigenes, accounting for 14.02% of all unigenes. The average length and distribution of these SSRs was about 16 bp and 5.24 kb, respectively. Dinucleotide repeat motifs were the main type, with a frequency of 55.87%, followed by trinucleotides (24.45%). There were 159 kinds of repeat motifs existing in the pear transcriptome. AG/CT was the most frequent motif, accounting for 49.64%. All 9154 SSR-containing unigenes were functionally annotated using Nr (NCBI non-redundant protein database), Nt (NCBI non-redundant nucleotide database), and the Swiss-Prot database, and were classified further by Gene Ontology and Clusters of Orthologous Groups. In addition, a total of 4300 primer pairs were designed from all SSR loci obtained. Of these, 40 primers were randomly selected for PCR amplification and polyacrylamide gel (PAGE) analysis. Among the 40 primer pairs, 31 were successfully separated via PAGE. These findings also confirm that mining SSRs using next-generating sequencing technologies is a fast, effective, and reliable approach. PMID- 27706777 TI - Novel and highly informative Capsicum SSR markers and their cross-species transferability. AB - This study was undertaken primarily to develop new simple sequence repeat (SSR) markers for Capsicum. As part of this project aimed at broadening the use of molecular tools in Capsicum breeding, two genomic libraries enriched for AG/TC repeat sequences were constructed for Capsicum annuum. A total of 475 DNA clones were sequenced from both libraries and 144 SSR markers were tested on cultivated and wild species of Capsicum. Forty-five SSR markers were randomly selected to genotype a panel of 48 accessions of the Capsicum germplasm bank. The number of alleles per locus ranged from 2 to 11, with an average of 6 alleles. The polymorphism information content was on average 0.60, ranging from 0.20 to 0.83. The cross-species transferability to seven cultivated and wild Capsicum species was tested with a set of 91 SSR markers. We found that a high proportion of the loci produced amplicons in all species tested. C. frutescens had the highest number of transferable markers, whereas the wild species had the lowest. Our results indicate that the new markers can be readily used in genetic analyses of Capsicum.

AB - Pseudomonas aeruginosa is one of the most important causes of nosocomial infection and it has increasing resistance to many antimicrobial agents. beta lactamase production is the most frequent mechanism for beta-lactam resistance in P. aeruginosa. We evaluated the prevalence of beta-lactamase genes in P. aeruginosa for classes A, C, and D by polymerase chain reaction, and investigated clonal diversity by pulsed-field gel electrophoresis (PFGE). We used the disk diffusion method to test 118 non-duplicate clinical isolates of P. aeruginosa for antimicrobial susceptibility. We identified 51 isolates (43.22%) as multidrug resistant P. aeruginosa, approximately 44.91% of which were resistant to ceftazidime. beta-lactamase genes were found in 80 isolates of P. aeruginosa (67.80%). The genes that encode VEB-1, AmpC, and OXA-10 were detected in 9 (7.62%), 75 (63.56%), and 18 (15.25%) of these isolates, respectively. The genes that encode PER-1, CTX-M, TEM-1 and derivatives, and SHV-1 were not found in any of the P. aeruginosa isolates. We identified 29 different pulsotypes by PFGE. Two predominant pulsotypes were found. In pulsotype 1, OXA- 10, which was co-produced with the AmpC gene, was predominant. Moreover, VEB-1-producing strains were found to be scattered in many pulsotypes, and AmpC-producing strains showed high pulsotype diversity. The prevalence of beta-lactamase genes in P. aeruginosa was represented by the genetic heterogeneity of OXA-10, AmpC, and VEB-1. The predominant clone of P. aeruginosa clinical isolates was OXA-10. This raises concern about oxacillinases among P. aeruginosa clinical isolates. PMID- 27706779 TI - Clinical significance of combined liver function and high-sensitivity C-reactive protein measurement in children with hand-foot-mouth disease. AB - Hand-foot-mouth disease (HFMD) is a common pediatric disease responsible for the development of rashes or herpes on the hand, foot, and mouth. Severe complications of HFMD include myocarditis, pulmonary edema, aseptic meningoencephalitis, and even death. Therefore, early diagnosis of HFMD is of particular importance. In this study, we determined the clinical value of the combined detection of liver function and high-sensitivity C-reactive protein (hs CRP) expression in children with HFMD. Three hundred children with HFMD were recruited to this study between July 2013 and July 2015 and divided into the mild and severe HFMD groups (N = 150 per group). The liver function [aspartate aminotransferase (AST), alanine transaminase (ALT), and alkaline phosphatase (ALP) levels] and hs-CRP expression were evaluated using standardized tests, and the clinical value of combined detection of these indices (in parallel and serially) was determined. Patients in the severe HFMD group showed significantly higher levels of ALT, AST, ALP, and hs-CRP compared to those in the mild HFMD group (P < 0.05). The hs-CRP and liver function tests had low specificity and sensitivity, respectively. However, parallel combined detection improved the sensitivity and negative predicted value of these indices, whereas serial combined detection improved the specificity and positive predicted value. In conclusion, hs-CRP and liver function play a major role in the diagnosis of HFMD (and identifying its severity), and serial combined detection of these indices enhances the positive predicted value, and could be employed to diagnose severe HFMD at an earlier stage. PMID- 27706781 TI - Direct sequencing of mutations in the copper-transporting P-type adenosine triphosphate (ATP7B) gene for diagnosis and pathogenesis of Wilson's disease. AB - Copper-transporting P-type adenosine triphosphatase (ATP7B) has been identified as the pathogenic gene in hepatolenticular degeneration, or Wilson's disease (WD). The aim of this study was to explore the correlation between genetic mutations and the clinical profile of WD, and to discuss the value of mutation examination in its diagnosis for providing a scientific basis for the development of a method to examine genetic mutations. Sixty-eight Chinese Han patients with WD and 20 controls were included in this study. The ATP7B gene in DNA extracted from patient blood samples was amplified by PCR and sequenced. These sequences were compared against corresponding gene sequences obtained from healthy controls to statistically analyze the genetic mutations. Five of the nineteen mutations in ATP7B were newly detected mutations; moreover, 8 of these mutations were polymorphic (2 were newly identified). The Arg778Leu and Pro992Leu mutations in exons 8 and 13 were detected at the highest mutation frequencies of 25.74 and 16.91%, respectively. The frequencies of all other mutations were below 5%. However, the clinical manifestations of WD did not differ significantly in patients with the Arg778Leu and Pro992Leu mutations. Therefore, these mutations were considered as hotspot mutations in Chinese WD patients. However, we observed no significant correlation between these genetic types and the clinical symptoms of WD. The correlation between the mutation genotype and disease phenotype remains to be elucidated. In conclusion, the highly sensitive and specific direct DNA sequencing method can be used to screen for the causative genes of WD. PMID- 27706780 TI - Clinical value of detection of immune index and inflammatory reaction changes in patients with autoimmune disease. AB - Previous studies have shown a close correlation between the generation of B cell autoantibodies and imbalances in T lymphocyte subpopulations and the occurrence of disease. In this study, we have analyzed the effects of abnormal expression of CD4+CD25+-regulatory T cells, T lymphocyte subpopulations, immunoglobulins, complement factors, inflammatory factors, and adhesion molecules in the peripheral blood on the occurrence and development of autoimmune disease. Eighty patients with autoimmune disease were randomly (equally) divided into active stage and stable-stage disease groups (according to pre-defined criteria). Fifty healthy people were recruited to the control group. The above-mentioned indices were detected by flow cytometry, immunity transmission turbidity, and enzyme linked immunosorbent assay. We observed an obvious decrease in the CD4+CD25+- regulatory T cell, CD4+ cell, CD4+/CD8+ cell, NK cell, C3, and C4 expression in all three groups; however, this decrease was statistically significant in the active-stage group (P < 0.05). Alternately, we observed a significant increase in the expression of CD8+ cells, immunoglobulin (Ig) A, IgG, IgM, tumor necrosis factor-alpha, interleukin (IL)-10, IL-17, interferon-g, intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and E-selectin expression in the active-stage group (P < 0.05). Therefore, inflammatory reactions and immune dysfunction occurs during the active-stage of autoimmune disease, and detection of the immune indices and inflammatory and adhesion factors could help evaluate the immune stage in these patients, providing an experimental basis for the determination of disease progression and clinical treatment. PMID- 27706782 TI - Selection of inbred maize (Zea mays L.) progenies by topcrosses conducted in contrasting environments. AB - The aim of this study was to identify inbred progenies of S0:1 maize (Zea mays L.) plants that were efficient at a low level of technology and responsive at a high level of technology through the use of topcrosses. Two contrasting environments were created using two levels of base fertilization and topdressing, so that the levels of nitrogen, phosphorus, and potassium were applied four times higher in one environment than in the other. We used S0:1 progenies derived from commercial hybrids in topcrosses with two testers (an elite line from the flint heterotic group and an elite line from the dent heterotic group). The progenies and three controls were evaluated in an augmented block design in Nossa Senhora das Dores, SE, Brazil in the 2010 crop season. The average grain yield in the high-technological level was 21.44% greater than that in the low-technological level. There were no changes in progeny behavior in the two technological levels for grain yield. The testers did not differ in the average grain yield of the progenies at the two technological levels. Therefore, it is possible to select progenies derived from commercial hybrids that have an efficient response to fertilization. PMID- 27706783 TI - Short Communication Quick method for identifying horse (Equus caballus) and donkey (Equus asinus) hybrids. AB - The domestication of the Equus genus 5000-6000 years ago has influenced the history of human civilization. As soon as horse and donkey species had been domesticated, they were crossbred, producing humanity's first documented attempt at animal genome manipulation. Since then, the mule (male donkey x female horse) and the reciprocal cross (the hinny, male horse x female donkey) have been the most common equine hybrids in the world. Due to their hybrid vigor, mules and hinnies have been intensively used for carrying loads and people and for tilling the land. Despite their importance, visual distinction of mules and hinnies is difficult due to high phenotypic resemblance. However, the distinction between these two hybrids is of pivotal importance for equid breeders and ranchers. In this study, an easy, low-cost, effective, and fast multiplex-polymerase chain reaction method was developed to distinguish the maternal origin of mules and hinnies, targeting the hyper-variable mitochondrial DNA D-loop region. This methodology can help breeders, ranchers, animal science professionals, and researchers manage their equine herds with more confidence and precision. PMID- 27706784 TI - Cloning and characterization of ChiMYB in Chrysanthemum indicum with an emphasis on salinity stress tolerance. AB - v-myb avianmyeloblastosis viral oncogene homolog (MYB) transcription factors are key regulators of stress responsive gene expression in plants. In this study, the MYB gene, ChiMYB (GenBank accession No. KT948997), was isolated from Chrysanthemum indicum, and was functionally characterized with an emphasis on salinity stress tolerance. The full ChiMYB cDNA sequence (948 bp) encoded a typical R2R3 MYB transcription factor that contained 315 amino acid residues and two MYB domains. The temporal expression pattern of ChiMYB was noted in C. indicum, and the highest level was detected in the roots, followed by leaves and stems. ChiMYB expression was induced by NaCl treatments, and transient expression of the fusion of ChiMYB and green fluorescent protein (GFP) indicated that the protein was targeted to the nuclei of onion epidermal cells. Arabidopsis plants overexpressing ChiMYB displayed improved tolerance to drought and salt stress. When under salt stress conditions, transgenic Arabidopsis plants had higher survival rates than non-transgenic wild-type plants. Chlorophyll content, intercellular CO2 concentration, photosynthetic rate, and stomatal conductance were higher in the transgenic Arabidopsis plants than in non-transgenic control plants. Further investigation revealed that ChiMYB was able to regulate the expression of RD29A, RAB18, COR15, ABI1, and ABA genes, which are involved in salt stress signaling pathways. Our findings demonstrated that ChiMYB is essential for plant responses to salt stress, and it may have great potential for the improvement of salt tolerance in crops. PMID- 27706785 TI - Enhancement of pectinase production by ultraviolet irradiation and diethyl sulfate mutagenesis of a Fusarium oxysporum isolate. AB - Fusarium oxysporum strain BM-201 was treated with ultraviolet (UV) radiation to obtain a high pectinase-producing strain. Mutant UV-10-41 was obtained and then treated by diethyl sulfate. Next, the mutant UV-diethyl sulfate-43 derived from UV-10-41 was selected as high pectinase-producing strain. Mutant UV-diethyl sulfate-43 was incubated on slant for 10 generations, demonstrating that the pectinase-producing genes were stable. Pectinase activity reached 391.2 U/mL, which is 73.6% higher than that of the original strain. PMID- 27706786 TI - Prominent contribution of Th1, Th17, and Tregs to the host response during M. neoaurum infection. AB - Nontuberculous mycobacteria are ubiquitous in outside environment and animals. As for nontuberculous mycobacteria infection, there is only limited information in humans regarding infection and the subsequent immune response, especially for Mycobacterium neoaurum. Here, haematoxylin-eosin and Ziehl-Neelsen staining were used to observe pathological changes and detect acid-fast bacilli in organ samples in mouse model. Flow cytometry and quantitative real-time polymerase chain reaction were performed to analyze the contribution of Th1, Th17 and Tregs to the host immune response. M. neoaurum caused chronic infection in mice, resulting in infiltrates with large aggregates of inflammatory cells, especially macrophages, in lung tissues. Our results indicated that 72% of CD4+ T cells appeared in the early days of infection, which was followed by a decrease to 47% by day 32, and then a rise to 76% by day 56. Moreover, we found higher frequency of IFN-g-producing CD4+ T cells and elevated mRNA expression of the transcription factor T-bet in the lungs; however, we observed lower mRNA expression of the transcription factor RORgt and lower frequency of IL-17-producing CD4+ T cells. A transient relative decrease in the number of Treg cells was observed in the lungs; however, the number of Tregs did not change significantly between the first and last day following infection. Thus, M. neoaurum causes chronic infection in C57BL/6 mice, with Th1, Th17, and Tregs playing a prominent role in the host response. The present study may lay the basis for further studies on the mechanisms underlying infection with nontuberculous mycobacteria. PMID- 27706787 TI - Effects of Varroa destructor on temperature and humidity conditions and expression of energy metabolism genes in infested honeybee colonies. AB - Varroa destructor mites pose an increasing global threat to the apicultural industry and agricultural ecology; however, the issue of whether certain environmental factors reflect the level of mite infection is far from resolved. Here, a wireless sensor network (WSN) system was used to examine how V. destructor, which has vital impacts on honeybee (Apis mellifera) health and survival, affects the temperature and humidity of honeybee hives in a field experiment. This approach may facilitate early identification of V. destructor in hives, and thus enable timely remedial action. Using quantitative PCR, we also evaluated the expression of two genes, adipokinetic hormone (AKH) and adipokinetic hormone receptor (AKHR).The results showed that temperature in highly infested broods was higher than that in broods with low infestation. Moreover, mite infection in honeybee colonies was positively correlated with temperature but negatively correlated with humidity (P < 0.05). Similar to previous observations, quantitative analysis suggested that the expression levels of AKH and AKHR from honeybees with low infection were significantly higher than those from bees with high infection (P < 0.01). These results showed that the expression levels of these genes in colonies with high mite infestation were closely associated with changes in hive temperature and humidity. This study demonstrates that Varroa infection not only causes changes in temperature inside honeybee colonies, but also affects the expression of honeybee energy metabolism genes. PMID- 27706788 TI - Synthesis and structure-activity relationship of oleanolic mono- or di-glycosides against Magnaporthe oryzae. AB - Saponins are naturally-occurring units with broad diversity and are usually recognized as phytoanticipins. In order to develop new saponin chemical entities with high activity against Magnaporthe oryzae, we selected oleanolic acid (OA), which has wide natural distribution and rich content in plants. We used the ability of OA to act as an aglycone for glycosylation to obtain information on the structure-activity relationship (SAR) for rational molecular pesticide design. Oleanolic mono- or di-glycosides were synthesized at either the C3 hydroxy and/or C28-carboxyl position, using trichloroacetimidate or glycosyl bromide donors, respectively. Structures were confirmed by [1H]-,[13C]-NMR. Furthermore, the activity of the synthesized glycosides against M. oryzae was assessed in vitro, based on the mycelium growth rate. The twenty five oleanolic mono- or di-glycosides comprised fourteen saponins with 3-monosaccharide residue 1a-1n, six saponins with 28-monosaccharide residue 2a-2f, and five saponins with 3, 28-monosaccharide residue 3a-3e; all showed different activities against M. oryzae according to their different structures. We concluded that the optimal oleanolic mono- and di-glycoside structure for activity against M. oryzae is a C3 connection of a hexose such as mannose, galactose, or glucose, in combination with a C28 connection to a small group such as allyl or a C3 connection to a pentose accompanied by a larger group such as another pentose or heptenyl at C28. PMID- 27706789 TI - Aquaporin 4 inhibition decreased synthesis of cytokines by acetazolamide in the hippocampus of rats with pentrazol-induced chronic epilepsy. AB - Epilepsy refers to a clinical syndrome generated by spontaneous seizures in the central nervous system. Epilepsy triggers a complex pathological process including inflammatory response and aquaporin 4 (AQP4) increase. It has been reported that AQP4 helps to enhance the immunological function of the central nervous system in pathological conditions, but the relationship between AQP4 and inflammatory cytokines is poorly understood in chronic epilepsy processes. As an inhibitor of sulfonamide carbonic anhydrase (CA), acetazolamide (AZA) may inhibit water infiltration through AQP4. In this context, pentylenetetrazole (PTZ) is used to induce the chronic epilepsy model in rats to study the chronic epilepsy effects of AQP4 inhibition on proinflammatory cytokine expression in the hippocampus and proinflammatory cytokine quantification analysis of the plasma. Based on the assumption that AQP4 regulates proinflammatory cytokine expression, this article aims to demonstrate this effect in chronic epilepsy of rats. Rats were divided into four groups and were treated with different drugs: saline (Control), acetazolamide (AZA), pentylenetetrazole (PTZ), and pentylenetetrazole plus acetazolamide (PTZ+AZA). The data showed that seizures increased proinflammatory cytokine expression and that AZA significantly inhibited AQP4 expression. Overall, the results suggested that AQP4 inhibition could weaken excitotoxicity in epileptogenesis by reducing proinflammatory cytokines in the hippocampus. The findings provide a new insight into the involvement of cerebral edema insult and proinflammatory cytokines in the process of chronic epilepsy. PMID- 27706790 TI - Prediction of protein subcellular multisite localization using a new feature extraction method. AB - A basic problem of proteomics is identifying the subcellular locations of a protein. One factor making the problem more complicated is that some proteins may simultaneously exist in two or more than two subcellular locations. To improve multisite prediction quality, it is necessary to use effective feature extraction methods. Here, we developed a new feature extraction method based on the pK value and frequencies of amino acids to represent a protein as a real values vector. Using this novel feature extraction method, the multi-label k-nearest neighbors (ML-KNN) algorithm and setting different weights into different attributes' ML KNN, known as wML-KNN, were employed to predict multiplex protein subcellular locations. The best overall accuracy rate on dataset S1 from the predictor of Virus-mPLoc was 59.92 and 86.04% on dataset S2 from Gpos-mPLoc, respectively. PMID- 27706791 TI - Short Communication Microsatellite loci in the tetraploid spined loach, Cobitis biwae, and cross-species amplification in four related species. AB - Fifteen microsatellite loci were identified in the tetraploid spined loach, Cobitis biwae (Teleostei: Cobitidae). Among these, 14 were polymorphic (5-31 alleles) and showed moderate to high cross-species amplification transferability in four related species, Cobitis matsubarai, Cobitis taenia, Misgurnus anguillicaudatus, and Misgurnus fossilis. The loci, described herein, will be useful for population genetics, phylogeny, parentage analysis, and detection of hybridization among Cobitis species.

AB - Maize (Zea mays L.) is one of the most important food crops throughout the world, and provides oil and proteins to humans and livestock. Kernel oil and protein content in maize are two complex quantitative traits. In order to identify quantitative trait loci (QTL) controlling oil and protein concentration in maize kernels, and to evaluate their genetic effects, QTL analysis was conducted on an F3:4 population derived from a cross between an inbred line with a low oil and protein concentration (Zheng58) and an inbred line with a higher oil and protein concentration (B73). A total of 189 polymorphic simple sequence repeat markers were used to construct a linkage map. Eleven QTLs for kernel oil concentration were detected on nine chromosomes, except for chromosome 9. A single QTL explained 4.6 to 11.1% of the phenotypic variance. Ten QTLs for kernel protein concentration were also detected on nine chromosomes, except for chromosome 9. A single QTL explained 4.2 to 11.4% of the phenotypic variance. Interestingly, novel QTLs for oil concentration (qOIL08-01 and qOIL10-01) and QTLs for protein concentration (qPRO01-01 and qPRO05-01) were specific to the population studied, which could explain 7.1 to 11.1% of the phenotypic variance. These results will provide better understanding of the genetic basis of oil and protein concentrations in maize. The markers closely linked with the QTLs will facilitate breeding of maize varieties with high oil and protein concentrations through molecular marker-assisted selection.

AB - The beet armyworm, Spodoptera exigua (Lepidoptera: Noctuidae), is an economically important pest that causes major losses in some main crop-producing areas of China. To control this pest effectively, it is necessary to investigate its population genetic diversity and genetic structure around the Bohai Gulf area of China. In this study, we used two mitochondrial genes, COI (578 bp) and Cytb (724 bp), to investigate its genetic diversity. We obtained 622 COI sequences and 462 Cytb sequences from 23 populations, and 28 and 73 haplotypes, respectively, were identified. Low to moderate levels of genetic diversity (COI: Hd = 0.267 +/- 0.023, Pi = 0.00082 +/- 0.00010; Cytb: Hd = 0.689 +/- 0.018, Pi = 0.00255 +/- 0.00029) for the total populations were observed. Phylogenetic and median-joining network analyses indicated no distinct geographical distribution pattern among the haplotypes. Overall, this study revealed that there was significant differentiation among the populations (COI: FST = 0.158, P < 0.001; Cytb: FST = 0.148, P < 0.001). FST values for Shenyang, Baoding, and Funing were significantly different to those for most of the other populations. Finally, unimodal mismatch distribution analysis, combined with negative neutrality test results, showed a recent population expansion of the beet armyworm around the Bohai Gulf area of China.

AB - Currently approved treatments for schizophrenia only minimally affect the cognitive features of the illness that are the most closely related to disability. Hence, there is now considerable effort to repurpose drugs for schizophrenia, and to seek agents that can improve cognition by targeting receptor systems other than the dopaminergic system. The results of these studies have been mixed thus far; however, this continues to be a high-priority area of schizophrenia research and an important unmet need. PMID- 27706798 TI - Evidence of NI-0101 pharmacological activity, an anti-TLR4 antibody, in a randomized phase I dose escalation study in healthy volunteers receiving LPS. AB - Toll-like receptor-4 (TLR4) pathways are major contributors to pathological inflammatory responses induced by tissue damage. NI-0101 is the first monoclonal antibody (mAb) blocking TLR4 signaling. This activity is independent of the ligand type and concentration, therefore, potentially blocking any TLR4 ligands. A phase I single ascending dose study was conducted in 73 healthy volunteers to evaluate NI-0101 tolerability, preliminary safety, pharmacokinetics (PKs), and pharmacodynamics (PDs), in absence and in presence of a systemic challenge with lipopolysaccharide (LPS), a TLR4 ligand. NI-0101 was well tolerated without safety concern. The PK profile was characterized by a half-life of ~10 days at high concentrations and by a rapid elimination at low concentrations due to expected target-mediated drug disposition. NI-0101 prevented cytokine release following ex vivo and in vivo LPS administration and prevented the C-reactive protein (CRP) increase and the occurrence of flu-like symptoms expected following the in vivo administration of LPS. PMID- 27706799 TI - Survival model construction guided by fit and predictive strength. AB - Survival model construction can be guided by goodness-of-fit techniques as well as measures of predictive strength. Here, we aim to bring together these distinct techniques within the context of a single framework. The goal is how to best characterize and code the effects of the variables, in particular time dependencies, when taken either singly or in combination with other related covariates. Simple graphical techniques can provide an immediate visual indication as to the goodness-of-fit but, in cases of departure from model assumptions, will point in the direction of a more involved and richer alternative model. These techniques appear to be intuitive. This intuition is backed up by formal theorems that underlie the process of building richer models from simpler ones. Measures of predictive strength are used in conjunction with these goodness-of-fit techniques and, again, formal theorems show that these measures can be used to help identify models closest to the unknown non proportional hazards mechanism that we can suppose generates the observations. Illustrations from studies in breast cancer show how these tools can be of help in guiding the practical problem of efficient model construction for survival data. PMID- 27706800 TI - Development and validation of algorithms for the detection of statin myopathy signals from electronic medical records. AB - The purpose of this study was to develop and validate sensitive algorithms to detect hospitalized statin-induced myopathy (SIM) cases from electronic medical records (EMRs). We developed four algorithms on a training set of 31,211 patient records from a large tertiary hospital. We determined the performance of these algorithms against manually curated records. The best algorithm used a combination of elevated creatine kinase (>4* the upper limit of normal (ULN)), discharge summary, diagnosis, and absence of statin in discharge medications. This algorithm achieved a positive predictive value of 52-71% and a sensitivity of 72-78% on two validation sets of >30,000 records each. Using this algorithm, the incidence of SIM was estimated at 0.18%. This algorithm captured three times more rhabdomyolysis cases than spontaneous reports (95% vs. 30% of manually curated gold standard cases). Our results show the potential power of utilizing data and text mining of EMRs to enhance pharmacovigilance activities. PMID- 27706801 TI - Collision-induced thermochemistry of reactions of dissociation of glycyl homopeptides-An experimental and theoretical analysis. AB - The research draws on experimental and theoretical data about energetics and kinetics of mass spectrometric (MS) reactions of glycyl homopenta- (G5) and glycyl homohexapeptides (G6). It shows the great applicability of the methods of quantum chemistry to predict MS profile of peptides using energetics of collision induced dissociation (CID) fragment species. Mass spectrometry is among irreplaceable methods, providing unambiguous qualitative, quantitative and structural information about analytes, applicable to many scientific areas like environmental chemistry; food chemistry; medicinal chemistry; and more. Our study could be considered of substantial interdisciplinary significance, where MS proteomics is widely used. The experimental design involves electrospray ionization (ESI) and CID MS/MS. Theoretical design is based on ab initio and density functional theory (DFT) methods. Experimental MS and theoretical free Gibbs energies as well as rate constants of fragment reactions are compared. The thermodynamic encompasses gas-phase and polar continuum analysis, including polar protic and aprotic solvents within temperature T = 10-500 K; dielectric constant epsilon = 0-78, pH, and ionic strengths MU = 0.001-1.0 mol dm-1 . There are computed and discussed 39 protonated forms of peptides at amide N- and -(NHC)=O centers; corresponding fragment ions studying their thermodynamic stability depending on experimental conditions. A correlation analysis between molecular conformations of parent ions and fragment species; their proton accepting ability and internal energy distribution is carried out. Data about ionization potentials (IPs) and electron affinities (EAs) are discussed, as well. PMID- 27706802 TI - Invasive Management for Elderly Adults with Acute Coronary Syndrome: Where Are We Now?

AB - BACKGROUND: The incidence of asymptomatic, sporadic, small non-functioning pancreatic neuroendocrine neoplasms (NF-PNENs) has increased in recent decades. Conservative treatment has been advocated for these tumours. The aim of this study was systematically to evaluate the literature on active surveillance and to compare this with surgical management for asymptomatic sporadic small NF-PNENs. METHODS: PubMed, Embase and the Cochrane Library were searched systematically for studies that compared the active surveillance of asymptomatic, sporadic, small NF PNENs with surgical management. PRISMA guidelines for systematic reviews were followed. RESULTS: After screening 3915 records, five retrospective studies with a total of 540 patients were included. Of these, 327 patients (60.6 per cent) underwent active surveillance and 213 (39.4 per cent) had surgery. There was wide variation in the tumour diameter threshold considered as inclusion criterion (2 cm to any size). The median length of follow-up ranged from 28 to 45 months. Measurable tumour growth was observed in 0-51.0 per cent of patients. Overall, 46 patients (14.1 per cent) underwent pancreatic resection after initial conservative treatment. In most patients the reason was an increase in tumour size (19 of 46). There were no disease-related deaths in the active surveillance group in any of the studies. CONCLUSION: This systematic review suggests that active surveillance of patients affected by sporadic, small, asymptomatic NF PNENs may be a good alternative to surgical treatment. PMID- 27706804 TI - Bisphosphonates for steroid-induced osteoporosis. AB - BACKGROUND: This is an update of a Cochrane Review first published in 1999. Corticosteroids are widely used in inflammatory conditions as an immunosuppressive agent. Bone loss is a serious side effect of this therapy. Several studies have examined the use of bisphosphonates in the prevention and treatment of glucocorticosteroid-induced osteoporosis (GIOP) and have reported varying magnitudes of effect. OBJECTIVES: To assess the benefits and harms of bisphosphonates for the prevention and treatment of GIOP in adults. SEARCH METHODS: We searched CENTRAL, MEDLINE and Embase up to April 2016 and International Pharmaceutical Abstracts (IPA) via OVID up to January 2012 for relevant articles and conference proceedings with no language restrictions. We searched two clinical trial registries for ongoing and recently completed studies (ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal). We also reviewed reference lists of relevant review articles. SELECTION CRITERIA: We included randomised controlled trials (RCTs) satisfying the following criteria: 1) prevention or treatment of GIOP; 2) adults taking a mean steroid dose of 5.0 mg/day or more; 3) active treatment including bisphosphonates of any type alone or in combination with calcium or vitamin D; 4) comparator treatment including a control of calcium or vitamin D, or both, alone or with placebo; and 4) reporting relevant outcomes. We excluded trials that included people with transplant associated steroid use. DATA COLLECTION AND ANALYSIS: At least two review authors independently selected trials for inclusion, extracted data, performed 'risk of bias' assessment and evaluated the certainty of evidence using the GRADE approach. Major outcomes of interest were the incidence of vertebral and nonvertebral fractures after 12 to 24 months; the change in bone mineral density (BMD) at the lumbar spine and femoral neck after 12 months; serious adverse events; withdrawals due to adverse events; and quality of life. We used standard Cochrane methodological procedures. MAIN RESULTS: We included a total of 27 RCTs with 3075 participants in the review. Pooled analysis for incident vertebral fractures included 12 trials (1343 participants) with high-certainty evidence and low risk of bias. In this analysis 46/597 (or 77 per 1000) people experienced new vertebral fractures in the control group compared with 31/746 (or 44 per 1000; range 27 to 70) in the bisphosphonate group; relative improvement of 43% (9% to 65% better) with bisphosphonates; absolute increased benefit of 2% fewer people sustaining fractures with bisphosphonates (5% fewer to 1% more); number needed to treat for an additional beneficial outcome (NNTB) was 31 (20 to 145) meaning that approximately 31 people would need to be treated with bisphosphonates to prevent new vertebral fractures in one person.Pooled analysis for incident nonvertebral fractures included nine trials with 1245 participants with low-certainty evidence (downgraded for imprecision and serious risk of bias as a patient-reported outcome). In this analysis 30/546 (or 55 per 1000) people experienced new nonvertebral fracture in the control group compared with 29/699 (or 42 per 1000; range 25 to 69) in the bisphosphonate group; relative improvement of 21% with bisphosphonates (33% worse to 53% better); absolute increased benefit of 1% fewer people with fractures with bisphosphonates (4% fewer to 1% more).Pooled analysis on BMD change at the lumbar spine after 12 months included 23 trials with 2042 patients. Eighteen trials with 1665 participants were included in the pooled analysis on BMD at the femoral neck after 12 months. Evidence for both outcomes was moderate-certainty (downgraded for indirectness as a surrogate marker for osteoporosis) with low risk of bias. Overall, the bisphosphonate groups reported stabilisation or increase in BMD, while the control groups showed decreased BMD over the study period. At the lumbar spine, there was an absolute increase in BMD of 3.5% with bisphosphonates (2.90% to 4.10% higher) with a relative improvement of 1.10% with bisphosphonates (0.91% to 1.29%); NNTB 3 (2 to 3). At the femoral neck, the absolute difference in BMD was 2.06% higher in the bisphosphonate group compared to the control group (1.45% to 2.68% higher) with a relative improvement of 1.29% (0.91% to 1.69%); NNTB 5 (4 to 7).Pooled analysis on serious adverse events included 15 trials (1703 participants) with low-certainty evidence (downgraded for imprecision and risk of bias). In this analysis 131/811 (or 162 per 1000) people experienced serious adverse events in the control group compared to 136/892 (or 147 per 1000; range 120 to 181) in the bisphosphonate group; absolute increased harm of 0% more serious adverse events (2% fewer to 2% more); a relative per cent change with 9% improvement (12% worse to 26% better).Pooled analysis for withdrawals due to adverse events included 15 trials (1790 patients) with low-certainty evidence (downgraded for imprecision and risk of bias). In this analysis 63/866 (or 73 per 1000) people withdrew in the control group compared to 76/924 (or 77 per 1000; range 56 to 107) in the bisphosphonate group; an absolute increased harm of 1% more withdrawals with bisphosphonates (95% CI 1% fewer to 3% more); a relative per cent change 6% worse (95% CI 47% worse to 23% better).Quality of life was not assessed in any of the trials. AUTHORS' CONCLUSIONS: There was high-certainty evidence that bisphosphonates are beneficial in reducing the risk of vertebral fractures with data extending to 24 months of use. There was low-certainty evidence that bisphosphonates may make little or no difference in preventing nonvertebral fractures. There was moderate certainty evidence that bisphosphonates are beneficial in preventing and treating corticosteroid-induced bone loss at both the lumbar spine and femoral neck. Regarding harm, there was low-certainty evidence that bisphosphonates may make little or no difference in the occurrence of serious adverse events or withdrawals due to adverse events. We are cautious in interpreting these data as markers for harm and tolerability due to the potential for bias.Overall, our review supports the use of bisphosphonates to reduce the risk of vertebral fractures and the prevention and treatment of steroid-induced bone loss. PMID- 27706805 TI - Bowel function and quality of life after local excision or total mesorectal excision following chemoradiotherapy for rectal cancer. AB - BACKGROUND: Local excision for rectal cancer is expected to offer a better functional outcome than conventional surgery. The aim of the present study was to compare quality of life and bowel function in patients with rectal cancer who underwent either local excision or conventional surgery after chemoradiotherapy. METHODS: This was a retrospective multicentre study. Patients who underwent local excision were compared with those who had mesorectal excision. Quality of life and bowel function were investigated using validated questionnaires (European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, EORTC QLQ-CR29 and Memorial Sloan-Kettering Cancer Center Bowel Function Instrument) at a median follow-up of 49 (range 13-95) months. Further analysis was undertaken of data from patients who underwent local excision alone compared with those requiring subsequent radical surgery. Statistical significance was set at P < 0.010. RESULTS: The mean constipation score was significantly better in the local excision group than in the mesorectal excision group (3.8 (95 per cent c.i. 0.3 to 7.2) versus 19.8 (12.1 to 27.4); P < 0.001). Compared with patients who underwent mesorectal excision, those who had local excision had less sensation of incomplete emptying (mean score 3.7 (3.4 to 4.0) versus 2.8 (2.5 to 3.1); P < 0.001) and second bowel movements within 15 min (mean score 3.6 (3.3 to 3.9) versus 3.0 (2.7 to 3.3); P = 0.006). Patients who underwent local excision alone scored better than those who had mesorectal excision, particularly for bowel function, who, in turn, scored better than patients requiring subsequent radical surgery following local excision. CONCLUSION: Patients who underwent local excision had a better quality of life and bowel function than those who underwent mesorectal excision. PMID- 27706806 TI - The Mind Bending Quest for Cognitive Enhancers. AB - Adequate cognitive functioning is essential for daily activities. When there is an insult to the brain, cognitive abilities can suffer, which, in turn, produce substantial medical and functional impairment. Advances in neurobiology, circuit neuroscience, and clinical assessment technology are converging in a manner that holds promise for the development of new pharmacological agents for cognitive enhancement in neuropsychiatric disease. PMID- 27706807 TI - Intermediate monocytes are increased in enthesitis-related arthritis, a category of juvenile idiopathic arthritis. AB - Microarray of peripheral blood (PB) and synovial fluid mononuclear cells (PBMC, SFMC) of patients with juvenile idiopathic arthritis-enthesitis-related arthritis (JIA-ERA) has shown the involvement of monocytes. On the basis of CD14 and CD16 expression, monocytes are classified as classical, intermediate and non classical. In response to Toll-like receptor (TLR) stimulation, intermediate monocytes produce proinflammatory cytokines and play a role in inflammatory diseases. Therefore, we have studied the microarray profile of monocytes, the frequency of their subsets and cytokine production. Monocyte-specific microarray analysis was performed in six healthy controls' PBMC and six patients' PBMC and SFMC using Illumina chips WG12. Monocyte subsets were assessed in 46 patients with JIA-ERA and 17 healthy controls and 17 disease controls by flow cytometry. Interleukin (IL)-23 and tumour necrosis factor (TNF) levels were measured in culture supernatants of eight controls and seven patients' PBMC/SFMC with/without lipopolysaccharide (LPS) stimulation. Cytokine-producing intermediate monocytes were assessed by flow cytometry. Genes related to antigen presentation, cytokine signalling and TLR pathway were regulated differentially in PB and synovial monocytes of patients with JIA-ERA. Key genes of intermediate monocytes, such as CLEC10A and MARCO, were expressed three- to fourfold more in JIA-ERA. In PB, the frequency of intermediate monocytes was significantly higher in JIA-ERA (4.90% +/ 3.5) compared to controls (1.8% +/- 1.06; P < 0.001). Patients' synovial cells also had more intermediate monocytes compared to PB (11.25% +/- 11.32, 5.9% +/- 4.8; P = 0.004). Intermediate monocytes are the major producers of IL-23. Thus, intermediate monocytes may play an important role in JIA-ERA, possibly by producing cytokines, and contribute to joint inflammation. PMID- 27706809 TI - Analytical Characterization of Polyphenols from Tara and Caesalpinia decapetala as Stabilizers of O/W Emulsions. AB - The extracts (0.5% [w/w]) from Caesalpinia spinosa or tara (CS) and Caesalpinia decapetala (CD) leaves were evaluated for their ability to inhibit lipid oxidation using oil-in-water (O/W) emulsions as the model system. Liquid chromatography (LC) combined with mass spectrometry (MS), using a hybrid quadrupole time-of-flight (QTOF) mass spectrometer, was employed for (1) the identification of potential antioxidant species in the extracts and (2) to follow their evolution through aging of the emulsions. CS extracts, containing esters and conjugated forms of gallic acid (GA), turned out to be more effective than CD, rich in flavonoid species, in stabilizing the O/W emulsions. After 3 wk at 33 degrees C, peroxide values of emulsions stabilized with CS and CD extracts were 6.7 and 18.2 meq hydroperoxides/kg, respectively. Responses measured for the oligomers and esterified forms of GA in CS containing emulsions decreased with time; however, the response for the free form of GA kept increasing. PMID- 27706810 TI - Antitumor effects of 4-methylumbelliferone, a hyaluronan synthesis inhibitor, on malignant peripheral nerve sheath tumor. AB - Hyaluronan (HA) has been shown to play important roles in the growth, invasion and metastasis of malignant tumors. Our previous study showing that high HA expression in malignant peripheral nerve sheath tumors (MPNST) is predictive of poor patient prognosis, prompted us to speculate that inhibition of HA synthesis in MPNST might suppress the tumorigenicity. The aim of our study was to investigate the antitumor effects of 4-methylumbelliferone (MU), an HA synthesis inhibitor, on human MPNST cells and tissues. The effects of MU on HA accumulation and tumorigenicity in MPNST cells were analyzed in the presence or absence of MU in an in vitro as well as in vivo xenograft model using human MPNST cell lines, sNF96.2 (primary recurrent) and sNF02.2 (metastatic). MU significantly inhibited cell proliferation, migration and invasion in both MPNST cell lines. HA binding protein (HABP) staining, particle exclusion assay and quantification of HA revealed that MU significantly decreased HA accumulation in the cytoplasms and pericellular matrices in both MPNST cell lines. The expression levels of HA synthase2 (HAS2) and HA synthase3 (HAS3) mRNA were downregulated after treatment with MU. MU induced apoptosis of sNF96.2 cells, but not sNF02.2 cells. MU administration significantly inhibited the tumor growth of sNF96.2 cells in the mouse xenograft model. To the best of our knowledge, our study demonstrates for the first time the antitumor effects of MU on human MPNST mediated by inhibition of HA synthesis. Our results suggest that MU may be a promising agent with novel antitumor mechanisms for MPNST. PMID- 27706808 TI - Understanding the regulation of pattern recognition receptors in inflammatory diseases - a 'Nod' in the right direction. AB - Nucleotide-binding oligomerization domain (NOD) -like receptors (NLRs) are a family of 23 receptors known as pattern recognition receptors; they are expressed in many cell types and play a key role in the innate immune response. The NLRs are activated by pathogen-associated molecular patterns, which include structurally conserved molecules present on the surfaces of bacteria. The activation of these NLRs by pathogens results in the downstream activation of signalling kinases and transcription factors, culminating in the transcription of genes coding for pro-inflammatory factors. Expression of NLR is altered in many cellular, physiological and disease states. There is a lack of understanding of the mechanisms by which NLR expression is regulated, particularly in chronic inflammatory states. Genetic polymorphisms and protein interactions are included in such mechanisms. This review seeks to examine the current knowledge regarding the regulation of this family of receptors and their signalling pathways as well as how their expression changes in disease states with particular focus on NOD1 and NOD2 in inflammatory bowel diseases among others. PMID- 27706812 TI - Multimodel Validity Assessment of Groundwater Flow Simulation Models Using Area Metric Approach. AB - We demonstrate the application of the Area Metric developed by Ferson et al. (2008) for multimodel validity assessment. The Area Metric quantified the degree of models' replicative validity: the degree of agreement between the observed data and the corresponding simulated outputs represented as their empirical cumulative distribution functions (ECDFs). This approach was used to rank multiple representations of a case study groundwater flow model of a landfill by their Area Metric scores. A multimodel approach allows to account for uncertainties that may either be epistemic (from lack of knowledge) or aleatory (from variability inherent in the system). The Area Metric approach enables explicit incorporation of model uncertainties, epistemic as well as aleatory, into validation assessment. The proposed approach informs understanding of the collected data and that of the model domain. It avoids model overfitting to a particular system state, and in fact is a blind assessment of the models' validity: models are not adjusted, or updated, to achieve a better numerical fit. This approach assesses the degree of models' validity, in place of the typical binary model validation/invalidation process. Collectively, this increases confidence in the model's representativeness that, in turn, reduces risk to model users. PMID- 27706811 TI - Oncogenic targets Mmp7, S100a9, Nppb and Aldh1a3 from transcriptome profiling of FAP and Pirc adenomas are downregulated in response to tumor suppression by Clotam. AB - Intervention strategies in familial adenomatous polyposis (FAP) patients and other high-risk colorectal cancer (CRC) populations have highlighted a critical need for endoscopy combined with safe and effective preventive agents. We performed transcriptome profiling of colorectal adenomas from FAP patients and the polyposis in rat colon (Pirc) preclinical model, and prioritized molecular targets for prevention studies in vivo. At clinically relevant doses in the Pirc model, the drug Clotam (tolfenamic acid, TA) was highly effective at suppressing tumorigenesis both in the colon and in the small intestine, when administered alone or in combination with Sulindac. Cell proliferation in the colonic crypts was reduced significantly by TA, coincident with increased cleaved caspase-3 and decreased Survivin, beta-catenin, cyclin D1 and matrix metalloproteinase 7. From the list of differentially expressed genes prioritized by transcriptome profiling, Mmp7, S100a9, Nppb and Aldh1a3 were defined as key oncogene candidates downregulated in colon tumors after TA treatment. Monthly colonoscopies revealed the rapid onset of tumor suppression by TA in the Pirc model, and the temporal changes in Mmp7, S100a9, Nppb and Aldh1a3, highlighting their value as potential early biomarkers for prevention in the clinical setting. We conclude that TA, an "old drug" repurposed from migraine, offers an exciting new therapeutic avenue in FAP and other high-risk CRC patient populations. PMID- 27706813 TI - Optimization of Vacuum Impregnation with Calcium Lactate of Minimally Processed Melon and Shelf-Life Study in Real Storage Conditions. AB - Vacuum impregnation (VI) is a processing operation that permits the impregnation of fruit and vegetable porous tissues with a fast and more homogeneous penetration of active compounds compared to the classical diffusion processes. The objective of this research was to investigate the impact on VI treatment with the addition of calcium lactate on qualitative parameters of minimally processed melon during storage. For this aim, this work was divided in 2 parts. Initially, the optimization of process parameters was carried out in order to choose the optimal VI conditions for improving texture characteristics of minimally processed melon that were then used to impregnate melons for a shelf-life study in real storage conditions. On the basis of a 23 factorial design, the effect of Calcium lactate (CaLac) concentration between 0% and 5% and of minimum pressure (P) between 20 and 60 MPa were evaluated on color and texture. Processing parameters corresponding to 5% CaLac concentration and 60 MPa of minimum pressure were chosen for the storage study, during which the modifications of main qualitative parameters were evaluated. Despite of the high variability of the raw material, results showed that VI allowed a better maintenance of texture during storage. Nevertheless, other quality traits were negatively affected by the application of vacuum. Impregnated products showed a darker and more translucent appearance on the account of the alteration of the structural properties. Moreover microbial shelf-life was reduced to 4 d compared to the 7 obtained for control and dipped samples. PMID- 27706814 TI - Consumer Acceptance of a Polyphenolic Coffee Beverage. AB - The objective of this study was to determine if Chardonnay grape seed pomace (GSP), a waste stream of wine production, could be used as a functional ingredient in brewed coffee. Two consumer panels were conducted to assess the acceptance of coffee at coffee replacement (w/w) values of 0% (control), 6.25%, 12.50%, 18.75%, or 25% GSP. The 1st consumer panel (n = 80) assessed the coffee samples served "black." The 2nd panel (n = 67) assessed the coffee samples with adjustment (that is, sweeteners, milk, and cream) options available. Consumer sensory evaluation involved evaluating the 5 treatments individually for acceptance of appearance, aroma, taste/flavor, and overall acceptance using a 9 point hedonic scale. A check-all-that-apply questionnaire surveyed the sensory attributes describing aroma, appearance, and taste/flavor of the samples. Oxygen radical absorbance capacity was used to measure the effects of antioxidant levels in GSP coffee samples. Results showed that GSP could be added at 6.25% replacement without significantly affecting the overall consumer acceptance of coffee compared to the control (0% GSP). Above 6.25% GSP supplementation, the coffee beverage was described as more tan, milky, watery/dilute, and mild, and was generally less accepted by the consumers. GSP also increased the antioxidant capacity of the coffee compared to the control (0% GSP), with no significant differences among replacement values. Therefore, 6.25% GSP replacement is recommended for creating coffee beverages acceptable to consumers. Further in vivo investigation may substantiate the free-radical scavenging capacity of GSP coffee and its potential health benefits. PMID- 27706815 TI - Influence of the Isolation Method on the Technofunctional Properties of Protein Isolates from Lupinus angustifolius L. AB - The technofunctional properties of 2 protein isolates from Lupinus angustifolius L. Vitabor isolated by different procedures were investigated. The lupin protein isolate prepared by aqueous alkaline extraction with subsequent isoelectric precipitation (ILP) showed a significantly higher degree of protein denaturation and lower denaturation temperatures than the one obtained by aqueous salt-induced extraction followed by dilutive precipitation (MLP) as determined by differential scanning calorimetry. Rheological investigations revealed higher firmness and a viscoelastic solid-like behavior of ILP, in contrast to MLP that showed viscoelastic, liquid-like properties. Protein solubility of MLP was higher compared to ILP and solubility minima were slightly different for both lupin protein isolates. The protein isolates exhibited different technofunctional properties with ILP showing higher water binding capacity, lower oil binding capacity and lower emulsifying capacity than MLP. This reflects the different putative application of both lupin protein isolates as food ingredients, for example for ILP as a moisture enhancer and for MLP as a "natural" emulsifier in mixed food systems. PMID- 27706816 TI - Prediagnosis body mass index and waist-hip circumference ratio in association with colorectal cancer survival. AB - The association of obesity on survival among patients with colorectal cancer (CRC) has not been well characterized. We investigated the association of prediagnostic body mass index (BMI)/waist-hip ratio (WHR) and total/cause specific mortality in CRC patients. Our study included 1,452 patients who participated in two large cohort studies and were diagnosed with CRC during follow-up period. Participants were measured for anthropometrics and interviewed to collect relevant information at baseline, prior to any cancer diagnosis. Data on site-specific cancer incidence and cause-specific mortality were obtained via in-person surveys and annual record linkage with cancer and vital statistics registries. Cox proportional hazard models were used to evaluate the associations of BMI and WHR with survival. A total of 547 participants died during the follow up period, including 499 who died of CRC. Relative to normal BMI (18.5 to <25.0 kg/m2 ), obesity (BMI >= 30 kg/m2 ) was associated with increased mortality resulting from all causes [hazard ratio (HR) = 1.5, 95% confidence interval (CI): 1.1-2.1] and CRC (HR = 1.5, 95% CI: 1.1-2.1). Elevated risk of death was also found among underweight patients (BMI < 18.5 kg/m2 ), although not all risk estimates were statistically significant. Overweight BMI (25.0 to <30.0 kg/m2 ) was not associated with risk of death among CRC patients, nor was WHR. In conclusion, prediagnostic BMI was associated with survival among CRC patients following a U-shape pattern; obesity was associated with high mortality after CRC diagnosis. These findings provide support for maintaining healthy weight to improve the survival of CRC patients. PMID- 27706817 TI - Fluorescence Imaging of Posterior Spiracles from Second and Third Instars of Forensically Important Chrysomya rufifacies (Diptera: Calliphoridae). AB - Entomological protocols for aging blowfly (Diptera: Calliphoridae) larvae to estimate the time of colonization (TOC) are commonly used to assist in death investigations. While the methodologies for analyzing fly larvae differ, most rely on light microscopy, genetic analysis, or, more rarely, electron microscopy. This pilot study sought to improve resolution of larval stage in the forensically important blowfly Chrysomya rufifacies using high-content fluorescence microscopy and biochemical measures of developmental marker proteins. We established fixation and mounting protocols, defined a set of measurable morphometric criteria and captured developmental transitions of 2nd instar to 3rd instar using both fluorescence microscopy and anti-ecdysone receptor Western blot analysis. The data show that these instars can be distinguished on the basis of robust, nonbleaching, autofluorescence of larval posterior spiracles. High-content imaging techniques using confocal microscopy, combined with morphometric and biochemical techniques, may therefore aid forensic entomologists in estimating TOC.

PMID- 27706818 TI - Efficient pole-search algorithm for dynamic polarizability: Toward alternative excited-state calculation for large systems. AB - This study presents an efficient algorithm to search for the poles of dynamic polarizability to obtain excited states of large systems with nonlocal excitation nature. The present algorithm adopts a homogeneous search with a constant frequency interval and a bisection search to achieve high accuracy. Furthermore, the subtraction process of the information about the detected poles from the total dynamic polarizability is used to extract the undetected pole contributions. Numerical assessments confirmed the accuracy and efficiency of the present algorithm in obtaining the excitation energies and oscillator strengths of all dipole-allowed excited states. A combination of the present pole-search algorithm and divide-and-conquer-based dynamic polarizability calculations was found to be promising to treat nonlocal excitations of large systems.

AB - One in 12 people worldwide suffers from diabetes and more than 90% of affected adult individuals are diagnosed with type 2 diabetes mellitus (T2DM). Obesity adds to the personal risk to develop T2DM, and both metabolic diseases are rampantly increasing worldwide. Over recent years, primary cilia have moved into the focus of basic and clinical research, after several human diseases have been identified as ciliopathies (i.e., they are linked to ciliary dysfunction). A subset of ciliopathies presents with obesity and diabetes, either as core symptoms or major complications. Several studies have shown a role for ciliary signaling in the satiety signaling centers of the hypothalamus and in other metabolically active tissues, such as pancreatic islets. Here, we discuss recent advances and perspectives in ciliary metabolic research. PMID- 27706821 TI - Higher bioavailability of iron from whole wheat bread compared with iron fortified white breads in caco-2 cell model: an experimental study. AB - BACKGROUND: Bread, as the staple food of Iranians, with average per capita consumption of 300 g d-1 , could potentially be a good vehicle for many fortificants, including iron. In this study, iron bioavailability from flat breads (three fortified and one whole wheat unfortified) was investigated using in vitro simulation of gastrointestinal digestion and absorption in a caco-2 cell model. RESULTS: Despite having a lower ferritin/protein ratio in comparison with fortified breads, whole wheat bread showed higher iron bioavailability than the other three types of bread. Assuming iron bioavailability from the ferrous sulfate supplement used as standard was about 10%, the estimated bioavailability of iron from the test breads was calculated as 5.0-8.0%. Whole wheat bread (~8%), as compared with the fortified breads (~5-6.5%), had higher iron bioavailability. CONCLUSION: Iron from unfortified whole wheat bread is more bioavailable than from three types of iron-fortified breads. (c) 2016 Society of Chemical Industry. PMID- 27706822 TI - Efficiency and apical extrusion of debris: a comparative ex vivo study of four retreatment techniques in severely curved root canals. AB - AIM: To compare the amount of apically extruded debris and of remaining filling material during the removal of root canal filling material using three rotary NiTi retreatment instruments or Hedstrom files. METHODOLOGY: Ninety-six severely curved human molars of both jaws were selected. The root canals were prepared to size X2 (tip size 25, .06 taper) using the ProTaper Next system (Dentsply Sirona, Ballaigues, Switzerland), filled with gutta-percha and AH Plus sealer (Dentsply De Trey, Konstanz, Germany) and then randomly divided into four experimental groups (n = 24 each) with two subgroups of maxillary and mandibular teeth each. An experimental model was used as a phantom head to simulate the upper and lower jaws. The root filling materials were removed with one of the following files using a crown-down preparation technique: I. Hedstrom files (H-files) (VDW, Munich, Germany), II. R-Endo (Micro-Mega, Besancon, France), III. Reciproc (VDW) and IV. ProTaper Universal Retreatment system (PTU-R) (Dentsply Maillefer). Apically extruded material was collected in vials, which were weighed with a microbalance (10-5 g) before and after the retreatment. The area of residual filling material in the coronal, middle and apical root level was assessed using digital analysis. These data were analysed statistically using ANOVA and the Kruskal-Wallis test. RESULTS: Reciproc was associated with significantly less extruded debris than the H-files (P = 0.009). No significant differences were detected amongst the four retreatment techniques concerning residual filling material (P = 0.082). The amount of extruded debris and areas of remaining filling material were not correlated (P = 0.901). Location of teeth in the maxilla or mandible had no impact on the amount of extruded debris within each instrument group (P = 0.609). However, when teeth were evaluated in general irrespective of the instruments, significantly more debris was extruded in the mandibular location (P < 0.001). CONCLUSIONS: All retreatment systems were associated with apical extrusion of debris, but H-files extruded significantly more material than Reciproc. Remnants of filling material were observed in all samples with no significant differences between the four techniques. PMID- 27706823 TI - Paper-based 1-MCP treatment suppresses cell wall metabolism and delays softening of Huanghua pears during storage. AB - BACKGROUND: Huanghua pear will lose its firmness quickly during postharvest storage at ambient temperature, and hence has limited storage and marketing potential. In this study, Huanghua pears treated with paper containing 0 (control) or 0.9 MUL L-1 1-methylcyclopropene (1-MCP) for 12 h, and then stored at (25 +/- 1) degrees C for 30 days, were investigated for the effect on fruit firmness, cell wall composition and activities of cell wall-degrading enzymes. RESULTS: Huanghua pears without 1-MCP treatment softened rapidly during room temperature storage and cell wall composition analyses showed an increase in water-soluble pectin (WSP) and decreases in cell wall materials (CWM) and cell wall components such as Na2 CO3 -soluble pectin (NSP), cellulose and hemicellulose. In contrast, the 1-MCP-treated fruits maintained higher firmness than the control; also, the treatment prevented the formation of WSP and reduced the degradation of CWM and cell wall components including NSP, cellulose and hemicellulose. 1-MCP treatment also significantly lowered the activities of cell wall-degrading enzymes such as pectinesterase, polygalacturonase, beta galactosidase and cellulase during storage. CONCLUSION: 1-MCP treatment can slow down the softening of Huanghua pears through reducing cell wall-degrading enzyme activities and hence maintain the integrity of the cell wall structure.

AB - The spatial structure of the vertical component of the electric field emitted by base stations in the Brussels region (Belgium) is measured, and studied using the variogram. A relationship between the variogram shape and base station antenna density in each measurement area is found; the variogram range and sill level are shown to depend on cellular base stations' antenna density, following exponential laws.

AB - Tendon injuries are common and present a clinical challenge because they often respond poorly to treatment and require prolonged rehabilitation. Current treatments often do not completely repair or regenerate the injured or diseased tendon to its native composition, structure, and mechanical properties. Stem cell based therapies have brought new hope for tissue repair and regeneration, including that for tendon rupture and tendinopathy. Despite tremendous effort and progress, the success of stem cell-based studies on tendon repair and regeneration has mainly been limited to preclinical studies with few clinical applications. In this concise review, we discuss basic understanding and translational challenges of using mesenchymal stem cells (MSCs) for tendon repair and regeneration, with a focus on (1) tendon stem/progenitor cells (TSPCs) and therapeutic approaches using TSPCs and other MSCs, (2) regulation of fate determination in MSCs for tendon-lineage differentiation, (3) pretreatment and condition of stem/progenitor cells for transplantation, and (4) a treatment approach that involves stimulating endogenous stem cells to enhance tendon healing. The review concludes with discussion on future directions. PMID- 27706826 TI - Long-Term Outcome and Complications Following Prophylactic Laparoscopic-Assisted Gastropexy in Dogs. AB - OBJECTIVE: To characterize the short- and long-term outcome (>12 months), complications, and owner satisfaction following prophylactic laparoscopic assisted gastropexy (LAG) in dogs. STUDY DESIGN: Retrospective study. ANIMALS: Client-owned dogs (n = 49). METHODS: Dogs that underwent prophylactic LAG at 2 veterinary academic hospitals were studied. Surgical time, anesthesia time, concurrent intra- and extra-abdominal procedures, and intraoperative and postoperative complications were recorded following review of medical records. Veterinarian and/or owner follow-up was obtained to determine outcome and satisfaction with LAG. RESULTS: Five of 49 dogs (10%) experienced complications related to abdominal access during LAG. Four percent (2/49) of dogs experienced an intraoperative complication. Follow-up information was available for 89% of dogs (44/49). Four dogs died of causes unrelated to LAG or gastric dilatation volvulus (GDV) in the follow-up period. Two dogs experienced major postoperative complications requiring additional veterinary intervention. Thirty percent (13 dogs) experienced a minor postoperative self-limiting wound-related complication. Median follow-up time was 698 days (range, 411-1825). No dogs experienced GDV. One hundred percent of dog owners were satisfied with LAG, would repeat the procedure in a future pet, and would recommend the procedure to a friend or family member. CONCLUSION: LAG was an effective procedure for prevention of GDV and was associated with high client satisfaction in this cohort of dogs. A moderate rate of postoperative wound complications occurred that were minor and self-limiting in nature. PMID- 27706828 TI - Pupil old/new effects reflect stimulus encoding and decoding in short-term memory. AB - We conducted five pupil old/new experiments to examine whether pupil old/new effects can be linked to familiarity and/or recollection processes of recognition memory. In Experiments 1-3, we elicited robust pupil old/new effects for legal words and pseudowords (Experiment 1), positive and negative words (Experiment 2), and low-frequency and high-frequency words (Experiment 3). Importantly, unlike for old/new effects in ERPs, we failed to find any effects of long-term memory representations on pupil old/new effects. In Experiment 4, using the words and pseudowords from Experiment 1, participants made lexical decisions instead of old/new decisions. Pupil old/new effects were restricted to legal words. Additionally requiring participants to make speeded responses (Experiment 5) led to a complete absence of old/new effects. Taken together, these data suggest that pupil old/new effects do not map onto familiarity and recollection processes of recognition memory. They rather seem to reflect strength of memory traces in short-term memory, with little influence of long-term memory representations. Crucially, weakening the memory trace through manipulations in the experimental task significantly reduces pupil/old new effects. PMID- 27706827 TI - Early Adolescent Trajectories of Impulsiveness and Sensation Seeking in Children of Fathers with Histories of Alcohol and Other Substance Use Disorders. AB - BACKGROUND: Problem substance use often begins in adolescence. This vulnerability likely stems, at least partially, from relatively rapid increases in sensation seeking occurring in early to mid-adolescence and more gradual improvements in impulse control occurring through later adolescence. Better understanding how these processes develop in high-risk youth may lead to enhanced substance use disorder treatment and prevention strategies. METHODS: We characterized trajectories of self-reported impulsivity and sensation seeking in 305 FH+ youths who at minimum had a father with a history of alcohol or other drug use disorders and 81 youths with no family histories of substance use disorders (FH-). Assessments started at ages 10 to 12 and continued at 6-month intervals for up to 42 months. In addition, a subset of 58 FH+ youths who began alcohol or other drug use before age 15 (FH+ Users) were compared to 58 FH+ propensity-matched adolescents who did not initiate substance use before age 15 (FH+ Non-Users). RESULTS: Compared to FH- youths at preadolescence, FH+ youths reported higher general impulsivity and higher impulsivity related to poor planning and attention. Over time, there were no differential effects of FH status on changes in impulsivity or sensation seeking across adolescence. FH+ Users had smaller decreases in general impulsivity and impulsivity related to restlessness and fidgeting across adolescence than FH+ Non-Users. FH+ Users also had greater increases in sensation seeking across adolescence than FH+ Non-Users. CONCLUSIONS: Increased impulsivity in FH+ youths may make them less able to regulate sensation seeking drives that peak in adolescence, which may contribute to their high risk for developing substance use disorders. Additionally, FH+ adolescents who initiate early use may be at increased risk in part due to increased impulsivity coupled with greater increases in sensation seeking. PMID- 27706829 TI - Lateral gene transfer, bacterial genome evolution, and the Anthropocene. AB - Lateral gene transfer (LGT) has significantly influenced bacterial evolution since the origins of life. It helped bacteria generate flexible, mosaic genomes and enables individual cells to rapidly acquire adaptive phenotypes. In turn, this allowed bacteria to mount strong defenses against human attempts to control their growth. The widespread dissemination of genes conferring resistance to antimicrobial agents has precipitated a crisis for modern medicine. Our actions can promote increased rates of LGT and also provide selective forces to fix such events in bacterial populations. For instance, the use of selective agents induces the bacterial SOS response, which stimulates LGT. We create hotspots for lateral transfer, such as wastewater systems, hospitals, and animal production facilities. Conduits of gene transfer between humans and animals ensure rapid dissemination of recent transfer events, as does modern transport and globalization. As resistance to antibacterial compounds becomes universal, there is likely to be increasing selection pressure for phenotypes with adverse consequences for human welfare, such as enhanced virulence, pathogenicity, and transmission. Improved understanding of the ecology of LGT could help us devise strategies to control this fundamental evolutionary process. PMID- 27706830 TI - Innovative ways of studying the effect of migration on obesity and diabetes beyond the common designs: lessons from the RODAM study. AB - Type 2 diabetes and obesity are major global public health problems, with migrant populations in high-income countries being particularly affected. Type 2 diabetes and obesity are also major threats in low- and middle-income countries, from which most migrant populations originate. Transitioning of societies and the resulting changes in lifestyles are thought to be major driving forces, but the key specific factors within this broad category still need to be determined. Migrant studies provide a unique opportunity to understand the potential underlying causes of these conditions, but current research is mainly geared toward analyzing the differences between migrants and the host populations in the countries of settlement. For better understanding, there is a need to extend migrant health research across national boundaries. This review discusses innovative ways of studying the effect of migration on type 2 diabetes and obesity beyond the common designs and the relevance of extending migrant health studies across national boundaries in the current era of increasing global migration. Specifically, we describe the burden and different methods for conducting migrant studies. We use the Research on Obesity and Diabetes among African Migrants (RODAM) study as a case study, discussing the methods, some results, and lessons learned, including challenges and an essential recipe for success that may guide future migrant health research. PMID- 27706831 TI - Evaluation of browning ratio in an image analysis of apple slices at different stages of instant controlled pressure drop-assisted hot-air drying (AD-DIC). AB - BACKGROUND: Computer vision-based image analysis systems are widely used in food processing to evaluate quality changes. They are able to objectively measure the surface colour of various products since, providing some obvious advantages with their objectivity and quantitative capabilities. In this study, a computer vision based image analysis system was used to investigate the colour changes of apple slices dried by instant controlled pressure drop-assisted hot air drying (AD DIC). RESULTS: The CIE L* value and polyphenol oxidase activity in apple slices decreased during the entire drying process, whereas other colour indexes, including CIE a*, b*, DeltaE and C* values, increased. The browning ratio calculated by image analysis increased during the drying process, and a sharp increment was observed for the DIC process. The change in 5-hydroxymethylfurfural (5-HMF) and fluorescent compounds (FIC) showed the same trend with browning ratio due to Maillard reaction. Moreover, the concentrations of 5-HMF and FIC both had a good quadratic correlation (R2 > 0.998) with the browning ratio. CONCLUSION: Browning ratio was a reliable indicator of 5-HMF and FIC changes in apple slices during drying. The image analysis system could be used to monitor colour changes, 5-HMF and FIC in dehydrated apple slices during the AD-DIC process. (c) 2016 Society of Chemical Industry. PMID- 27706832 TI - Evolutionary potential of upper thermal tolerance: biogeographic patterns and expectations under climate change. AB - How will organisms respond to climate change? The rapid changes in global climate are expected to impose strong directional selection on fitness-related traits. A major open question then is the potential for adaptive evolutionary change under these shifting climates. At the most basic level, evolutionary change requires the presence of heritable variation and natural selection. Because organismal tolerances of high temperature place an upper bound on responding to temperature change, there has been a surge of research effort on the evolutionary potential of upper thermal tolerance traits. Here, I review the available evidence on heritable variation in upper thermal tolerance traits, adopting a biogeographic perspective to understand how heritability of tolerance varies across space. Specifically, I use meta-analytical models to explore the relationship between upper thermal tolerance heritability and environmental variability in temperature. I also explore how variation in the methods used to obtain these thermal tolerance heritabilities influences the estimation of heritable variation in tolerance. I conclude by discussing the implications of a positive relationship between thermal tolerance heritability and environmental variability in temperature and how this might influence responses to future changes in climate. PMID- 27706833 TI - Pancreatic adenocarcinoma up-regulated factor has oncogenic functions in oral squamous cell carcinoma. AB - AIMS: Pancreatic adenocarcinoma up-regulated factor (PAUF) is a novel secretory protein which promotes tumour progression, metastasis and poor prognosis in pancreatic, cervical and colorectal carcinoma. It is also associated with gemcitabine resistance in pancreatic cancer cells. However, the expression and function of PAUF in oral squamous cell carcinoma (OSCC) remain unknown. METHODS AND RESULTS: We performed an immunohistochemical analysis of PAUF in 222 clinicopathologically characterized cases of OSCC. We also investigated the growth, invasion, apoptosis induction and cisplatin resistance of OSCC cells under PAUF knockdown treatment. PAUF was localized in normal salivary glands. In OSCC, immunostaining for PAUF was found in 52 of 222 patients (23.4%), and correlated with nodal metastasis (P < 0.0001) and poor prognosis (P < 0.0001). Multivariate analysis using the Cox proportional hazards model identified that PAUF expression was an independent predictor of disease-free survival in OSCC (P < 0.0001). The down-regulation of PAUF in OSCC cells suppressed cell growth and invasion and induced apoptosis and cisplatin sensitivity. CONCLUSIONS: Our results suggest that PAUF has tumour-promoting functions in OSCC. It may thus be a useful diagnostic and therapeutic marker for OSCC. PMID- 27706834 TI - Do contextual factors have a role in periodontal disease? AB - AIM: To explore the association between contextual factors and periodontal disease. METHODS: We pooled individual-level data from 20,204 35-44-year-olds and 9,666 65-74-year- olds, who participated in the 3rd National Oral Health Survey in China (2005), with province-level data from different sources. The association of provincial macroeconomic factors [Gross Domestic Product (GDP) per capita and Gini coefficient], health resources (public health expenditure, dentist-to population ratio and dental-therapist-to-population ratio), demographic composition (proportion of rural population and minority ethnic groups) and tobacco industry (tobacco crops, cigarette production and proportion of smokers) with the numbers of teeth with periodontal pocket depth (PPD) >= 4 mm and loss of attachment (LOA) >= 4 mm were assessed in multilevel models, controlling for individual-level demographic, socioeconomic and behavioural factors. RESULTS: Only the proportion of smokers at province level was associated with the number of teeth with PPD >= 4 mm and only among senior adults. However, public health expenditure, dentist-to-population ratio and the proportion of minority ethnic groups were associated with the number of teeth with LOA >= 4 mm in both age groups. GDP per capita was also associated with the number of teeth with LOA >= 4 mm only among 35-44-year-olds. CONCLUSION: Contextual factors may contribute to periodontal disease and help explain geographical inequalities among Chinese adults. PMID- 27706835 TI - Using pedagogical approaches to influence evidence-based practice integration - processes and recommendations: findings from a grounded theory study. AB - AIMS: The study aimed to explore the processes undertaken by nurse academics when integrating evidence-based practice (EBP) into their teaching and learning practices. This article focuses on pedagogical approaches employed by academics to influence evidence-based practice integration into undergraduate programs across Australian universities. BACKGROUND: Nursing academics are challenged to incorporate a variety of teaching and learning strategies to teach evidence-based practice and determine their effectiveness. However, literature suggests that there are limited studies available focusing on pedagogical approaches in evidence-based practice education. DESIGN: A constructivist grounded theory methodology, informed by Charmaz was used for this study. METHODS: Data were collected during 2014 from 23 nurse academics across Australian universities through semi-structured interviews. Additionally, nine were observed during teaching of undergraduate students. Twenty subject outlines were also analysed following Charmaz's approach of data analysis. FINDINGS: 'Influencing EBP integration' describes the pedagogical approaches employed by academics to incorporate EBP knowledge and skills into undergraduate curricula. With the use of various teaching and learning strategies, academics attempted to contextualize EBP by engaging students with activities aiming to link evidence to practice and with the EBP process. Although, some strategies appeared to be engaging, others were traditional and seemed to be disengaging for students due to the challenges experienced by participants that impeded the use of the most effective teaching methods. CONCLUSION: Study findings offer valuable insights into the teaching practices and identify some key challenges that require the adoption of appropriate strategies to ensure future nurses are well prepared in the paradigm of evidence-based practice. PMID- 27706837 TI - Propranolol enhances bone healing and implant osseointegration in rats tibiae. AB - BACKGROUND: Propranolol, a non-selective beta-blocker widely used to treat cardiovascular conditions, favours bone accrual. Accordingly, we hypothesized that propranolol could be useful for improving bone healing and osseointegration. This in vivo study was designed to investigate the effect of propranolol on bone healing and osseointegration in rats' tibiae. METHODS: On 24 Sprague-Dawley rats, a unicortical defect was created in the right tibial metaphysis of each rat and a custom-made titanium implant was placed in the left tibia. Animals were then assigned into two groups (n = 12, each group) and treated daily with either propranolol (5 mg/kg: subcutaneous) or saline, for 2 weeks. Then, after killing, the volume of the cortical defects (mm3) and the percentages of newly formed bone in the defects, were assessed with microcomputed tomography; bone-implant contact percentage and peri-implant bone volume/tissue volume were assessed by histomorphometry. RESULT: Propranolol-treated rats presented smaller cortical defects (1.56 +/- 0.28 mm3 versus 2.04 +/- 0.29 mm3 , p < 0.001) with more bone volume/tissue volume (60.6 +/- 7.9% versus 41.1 +/- 10.2%, p < 0.001) compared to saline-treated rats. Propranolol also enhanced osseointegration as propranolol treated rats presented higher bone-implant-contact (65.0 +/- 13.1% versus 42.5 +/ 8.8%, p < 0.001) and peri-implant bone volume/Tissue volume (73.8 +/- 10.1% versus 56.9 +/- 5.7%, p = 0.007) than saline-treated rats. CONCLUSION: Propranolol enhanced bone healing and implant osseointegration. PMID- 27706836 TI - Identifying nonalcoholic fatty liver disease patients with active fibrosis by measuring extracellular matrix remodeling rates in tissue and blood. AB - : Excess collagen synthesis (fibrogenesis) in the liver plays a causal role in the progression of nonalcoholic fatty liver disease (NAFLD). Methods are needed to identify patients with more rapidly progressing disease and to demonstrate early response to treatment. We describe here a novel method to quantify hepatic fibrogenesis flux rates both directly in liver tissue and noninvasively in blood. Twenty-one patients with suspected NAFLD ingested heavy water (2 H2 O, 50-mL aliquots) two to three times daily for 3-5 weeks prior to a clinically indicated liver biopsy. Liver collagen fractional synthesis rate (FSR) and plasma lumican FSR were measured based on 2 H labeling using tandem mass spectrometry. Patients were classified by histology for fibrosis stage (F0-F4) and as having nonalcoholic fatty liver or nonalcoholic steatohepatitis (NASH). Magnetic resonance elastography measurements of liver stiffness were also performed. Hepatic collagen FSR in NAFLD increased with advancing disease stage (e.g., higher in NASH than nonalcoholic fatty liver, positive correlation with fibrosis score and liver stiffness) and correlated with hemoglobin A1C. In addition, plasma lumican FSR demonstrated a significant correlation with hepatic collagen FSR. CONCLUSION: Using a well-characterized cohort of patients with biopsy-proven NAFLD, this study demonstrates that hepatic scar in NASH is actively remodeled even in advanced fibrosis, a disease that is generally regarded as static and slowly progressive. Moreover, hepatic collagen FSR correlates with established risks for fibrotic disease progression in NASH, and plasma lumican FSR correlates with hepatic collagen FSR, suggesting applications as direct or surrogate markers, respectively, of hepatic fibrogenesis in humans.

AB - Sleep-related complaints are widely prevalent in those with alcohol dependence (AD). AD is associated not only with insomnia, but also with multiple sleep related disorders as a growing body of literature has demonstrated. This article will review the various aspects of insomnia associated with AD. In addition, the association of AD with other sleep-related disorders will be briefly reviewed. The association of AD with insomnia is bidirectional in nature. The etiopathogenesis of insomnia has demonstrated multiple associations and is an active focus of research. Treatment with cognitive behavioral therapy for insomnia is showing promise as an optimal intervention. In addition, AD may be associated with circadian abnormalities, short sleep duration, obstructive sleep apnea, and sleep-related movement disorder. The burgeoning knowledge on insomnia associated with moderate-to-severe alcohol use disorder has expanded our understanding of its underlying neurobiology, clinical features, and treatment options. PMID- 27706839 TI - Influence of type D personality on job stress and job satisfaction in clinical nurses: the mediating effects of compassion fatigue, burnout, and compassion satisfaction. AB - AIMS: To test a hypothetical path model evaluating the influence of type D personality on job stress and job satisfaction and to identify the mediating effects of compassion fatigue, burnout, and compassion satisfaction among clinical nurses in South Korea. BACKGROUND: Personalities susceptible to stress, compassion fatigue, and burnout in clinical nurses have negative effects on the job stress and job satisfaction. DESIGN: A correlational, cross-sectional design was used. METHODS: A convenience sample of 875 clinical nurses was recruited between December 2014 - February 2015. The structured questionnaires included the Type D personality scale-14, Professional Quality of Life, job stress, job satisfaction, and general characteristics. To test the hypothetical path model, we performed a path analysis by using the AMOS 18.0 program. FINDINGS: Based on the path model, type D personality was significantly associated with compassion fatigue, burnout, and compassion satisfaction in our study subjects. Type D personality was significantly associated with job stress and job satisfaction via the effect of burnout, compassion satisfaction, and job stress. CONCLUSION: Since type D personality is associated with job stress and job satisfaction, identifying personalities vulnerable to stress would help to address job stress and to enhance job satisfaction when nurses have a high level of compassion fatigue and burnout and a low level of compassion satisfaction. The development of interventions that can reduce negative affect and social inhibition of nurses with type D personality and investigation of methods to decrease their compassion fatigue and burnout and to increase compassion satisfaction should be encouraged. PMID- 27706840 TI - Models of partnership within family-centred care in the acute paediatric setting: a discussion paper. AB - AIMS: A discussion of partnership in the context of family-centred care in the acute paediatric setting, through a critical analysis of partnership models. BACKGROUND: Paediatric healthcare practitioners understand the importance of family-centred care, but struggle with how to translate the core tenets into action and are confused by several rival terms. Partnering relationships are included in definitions of family-centred care, yet less is known about strategies to fully engage or support parents in these partnerships. A rigorous examination of concepts embedded in family-centred care such as partnership may provide a better understanding of how to implement the broader concept and support exemplary care in today's clinical practice environment. DESIGN: Discussion paper. DATA SOURCES: Electronic search (January 2000 - December 2014) performed on CINAHL, Medline, EMBASE, Sociological Abstracts and PsychINFO using keywords partnership, family-centred care and conceptual framework. Eligible references were drawn from the databases, reference lists and expert sources. Eight models met inclusion criteria and had currency and relevance to the acute paediatric setting. IMPLICATIONS FOR NURSING: Nurses should continue exploring partnership in various paediatric contexts given the wide-ranging definitions, lack of operational indicators and need for stronger relational statements in current models. An examination of key strategies, barriers and facilitators of partnership is recommended. CONCLUSION: One partnership model had both high overall maturity and best fit with family-centred care principles. All models originate from Western and developed countries, indicating that future partnership models should be more geographically, culturally and economically diverse. PMID- 27706841 TI - Periodontal pocketing and gingival bleeding in relation to Nordic diet - results from a population-based survey. AB - AIM: To examine whether a Nordic diet measured by the Baltic Sea Diet Score (BSDS) and the Recommended Finnish Diet Score (RFDS) is associated with periodontal condition. MATERIAL AND METHODS: The study population consisted of non-smoking, non-diabetic and non-rheumatoid individuals in the Health 2000 Survey in Finland. Analyses were made in two age groups (30-49 years (n = 1210) and 50-79 years (n = 977)) and subsequently in two oral hygiene groups (good oral hygiene and poor oral hygiene). The number of sextants with gingival bleeding and the number of teeth with deepened periodontal pockets were used as outcome variables. Dietary data were collected by a validated food frequency questionnaire. RESULTS: Both the BSDS and the RFDS were weakly, although statistically significantly associated with less gingival bleeding in the younger age group (p = 0.019, p < 0.001). In the older age group, the RFDS or the BSDS associated inversely, although inconsistently, with gingival bleeding. RFDS and BSDS associated with both gingival bleeding and deepened periodontal pockets among those with poor oral hygiene. CONCLUSIONS: The results suggest that the Nordic diet in some cases has a favourable effect on periodontal health. These findings warrant further studies on the role of diet in periodontal diseases. PMID- 27706842 TI - Hierarchical Analysis of Self-Assembled PEGylated Hexaphenylalanine Photoluminescent Nanostructures. AB - Despite the growing literature about diphenylalanine-based peptide materials, it still remains a challenge to delineate the theoretical insight into peptide nanostructure formation and the structural features that could permit materials with enhanced properties to be engineered. Herein, we report the synthesis of a novel peptide building block composed of six phenylalanine residues and eight PEG units, PEG8 -F6. This aromatic peptide self-assembles in water in stable and well ordered nanostructures with optoelectronic properties. A variety of techniques, such as fluorescence, FTIR, CD, DLS, SEM, SAXS, and WAXS allowed us to correlate the photoluminescence properties of the self-assembled nanostructures with the structural organization of the peptide building block at the micro- and nanoscale. Finally, a model of hexaphenylalanine in aqueous solution by molecular dynamics simulations is presented to suggest structural and energetic factors controlling the formation of nanostructures. PMID- 27706843 TI - Organometallic Derivatization of the Nematocidal Drug Monepantel Leads to Promising Antiparasitic Drug Candidates. AB - The discovery of novel drugs against animal parasites is in high demand due to drug-resistance problems encountered around the world. Herein, the synthesis and characterization of 27 organic and organometallic derivatives of the recently launched nematocidal drug monepantel (Zolvix(r) ) are described. The compounds were isolated as racemates and were characterized by 1 H, 13 C, and 19 F NMR spectroscopy, mass spectrometry, and IR spectroscopy, and their purity was verified by microanalysis. The molecular structures of nine compounds were confirmed by X-ray crystallography. The anthelmintic activity of the newly designed analogues was evaluated in vitro against the economically important parasites Haemonchus contortus and Trichostrongylus colubriformis. Moderate nematocidal activity was observed for nine of the 27 compounds. Three compounds were confirmed as potentiators of a known monepantel target, the ACR-23 ion channel. Production of reactive oxygen species may confer secondary activity to the organometallic analogues. Two compounds, namely, an organic precursor (3 a) and a cymantrene analogue (9 a), showed activities against microfilariae of Dirofilaria immitis in the low microgram per milliliter range. PMID- 27706844 TI - Does Topology Dictate the Incidence of the Twist-Bend Phase? Insights Gained from Novel Unsymmetrical Bimesogens. AB - We prepared a significant number of unsymmetrical liquid-crystalline dimers that exhibit the twist-bend nematic phase; a state of matter that exhibits spontaneous breaking of mirror symmetry and, for some materials, a microsecond electrooptic response. A number of novel unsymmetrical bimesogens were synthesized and in comparing their thermal behaviour to previous literature examples, we have uncovered an unexpected relationship between the thermal stability of the nematic and NTB phases. This relationship demonstrates that molecular shape dictates the incidence of this fascinating phase of matter and leads us to speculate as to the existence of "twist-bend nematic phases" on length scales beyond those of the molecule.

PMID- 27706846 TI - Predictive significance of the European LeukemiaNet classification of genetic aberrations in patients with acute myeloid leukaemia undergoing allogeneic stem cell transplantation. AB - OBJECTIVES: The purpose of this study was to evaluate the predictive capacity of the European LeukemiaNet (ELN) classification of genetic risk in patients with acute myeloid leukaemia (AML) undergoing allogeneic stem cell transplantation (alloSCT). METHODS: We retrospectively analysed 274 patients transplanted at our centre between 2004 and 2014. RESULTS: The ELN grouping is comparable to the Southwest Oncology Group/Eastern Cooperative Oncology Group (SWOG/ECOG) stratification in predicting the outcome after alloSCT [overall P = 0.0064 for disease-free survival (DFS), overall P = 0.003 for relapse]. Patients with an intermediate-1 profile have a significantly elevated 5-yr relapse incidence as compared to favourable risk patients, that is 40% vs. 15%, [hazard ratio (HR) 2.58, P = 0.048]. An intermediate-1 risk profile is an independent predictor for relapse as determined by multivariate Cox regression analysis (HR 3.05, P = 0.023). In intermediate-1 patients, the presence of an FLT3 internal tandem duplication (FLT3-ITD) is associated with a significantly increased relapse incidence (P = 0.0323), and a lower DFS (P = 0.0465). FLT3-ITD is an independent predictor for overall survival, DFS and relapse incidence in the intermediate-1 subgroup. CONCLUSIONS: The ELN stratification of genetic risk predicts the outcome of patients with AML undergoing alloSCT. Patients with an intermediate-1 profile have a high risk for treatment failure due to relapse, which prompts the development of alternative treatment strategies. PMID- 27706847 TI - Structurally diverse dehydroshikimate dehydratase variants participate in microbial quinate catabolism. AB - Quinate and shikimate can be degraded by a number of microbes. Dehydroshikimate dehydratases (DSDs) play a central role in this process, catalyzing the conversion of 3-dehydroshikimate to protocatechuate, a common intermediate of aromatic degradation pathways. DSDs have applications in metabolic engineering for the production of valuable protocatechuate-derived molecules. Although a number of Gram-negative bacteria are known to catabolize quinate and shikimate, only limited information exists on the quinate/shikimate catabolic enzymes found in these organisms. Here, we have functionally and structurally characterized a putative DSD designated QuiC1, which is present in some pseudomonads. The QuiC1 protein is not related by sequence with previously identified DSDs from the Gram negative genus, Acinetobacter, but instead shows limited sequence identity in its N-terminal half with fungal DSDs. Analysis of a Pseudomonas aeruginosa quiC1 gene knock-out demonstrates that it is important for growth on either quinate or shikimate. The structure of a QuiC1 enzyme from P. putida reveals that the protein is a fusion of two distinct modules: an N-terminal sugar phosphate isomerase-like domain associated with DSD activity and a novel C-terminal hydroxyphenylpyruvate dioxygenase-like domain. The results of this study highlight the considerable diversity of enzymes that participate in quinate/shikimate catabolism in different microbes. PMID- 27706848 TI - Melatonin attenuates postmyocardial infarction injury via increasing Tom70 expression. AB - Mitochondrial dysfunction leads to reactive oxygen species (ROS) overload, exacerbating injury in myocardial infarction (MI). As a receptor for translocases in the outer mitochondrial membrane (Tom) complex, Tom70 has an unknown function in MI, including melatonin-induced protection against MI injury. We delivered specific small interfering RNAs against Tom70 or lentivirus vectors carrying Tom70a sequences into the left ventricles of mice or to cultured neonatal murine ventricular myocytes (NMVMs). At 48 h post-transfection, the left anterior descending coronary arteries of mice were permanently ligated, while the NMVMs underwent continuous hypoxia. At 24 h after ischemia/hypoxia, oxidative stress was assessed by dihydroethidium and lucigenin-enhanced luminescence, mitochondrial damage by transmission electron microscopy and ATP content, and cell apoptosis by terminal deoxynucleotidyl transferase dUTP nick-end labeling and caspase-3 assay. At 4 weeks after ischemia, cardiac function and fibrosis were evaluated in mice by echocardiography and Masson's trichrome staining, respectively. Ischemic/hypoxic insult reduced Tom70 expression in cardiomyocytes. Tom70 downregulation aggravated post-MI injury, with increased mitochondrial fragmentation and ROS overload. In contrast, Tom70 upregulation alleviated post MI injury, with improved mitochondrial integrity and decreased ROS production. PGC-1alpha/Tom70 expression in ischemic myocardium was increased with melatonin alone, but not when combined with luzindole. Melatonin attenuated post-MI injury in control but not in Tom70-deficient mice. N-acetylcysteine (NAC) reversed the adverse effects of Tom70 deficiency in mitochondria and cardiomyocytes, but at a much higher concentration than melatonin. Our findings showed that Tom70 is essential for melatonin-induced protection against post-MI injury, by breaking the cycle of mitochondrial impairment and ROS generation. PMID- 27706849 TI - Assignment of oxime and hydrazone configuration using 1 H-15 N and 13 C-15 N coupling measurements at natural abundance. AB - Measurement of 1 H-15 N and 13 C-15 N coupling constants at natural abundance is demonstrated to be a reliable and generic method to determine the configuration of oximes, hydrazines, and related systems. Data on 1 H-15 N and 13 C-15 N coupling constants on a variety of systems obtained at natural abundance confirm the geometric dependence of the measured 1 H-15 N and 13 C-15 N coupling constants. In addition, we summarize a simple "decision-tree" for determining configuration based on practical considerations of sample quantity, solubility, and complexity.

AB - Three tetrapheynlethylene derivatives (N,N-di(4-methoxyphenyl)aminophenyl substituted tetraphenylethylene; TPE-4DPA) with different methoxy positions (pp-, pm-, and po-) have been synthesized and characterized. The methoxy groups can control the oxidation potential of the materials, and the electronic properties of the derivatives were affected by the position of the methoxy substituents. These compounds were synthesized in a facile and cost-effective way, and were applied as hole-transport materials in perovskite solar cells. The corresponding cell performances were compared with respect to their structure modifications, and it was found that the derivative with m-OMe substituents showed the highest power conversion efficiency (PCE) of 15.4 %, with a Jsc value of 20.04 mA cm-2 , a Voc value of 1.07 V, and a fill factor (FF) value of 0.72, which is higher than the p-OMe and o-OMe substituents. Moreover, the PCE of pm-TPE-4DPA is comparable with that of the state-of-the-art 2,2',7,7'-tetrakis(N,N'-di-p methoxyphenylamine)-9,9'-spirobifluorene under identical conditions.

AB - A series of neutral long-lived purely organic radicals based on the stable [4-(N carbazolyl)-2,6-dichlorophenyl]bis(2,4,6-trichlorophenyl)methyl radical adduct (Cbz-TTM) is reported herein. All compounds exhibit ambipolar charge-transport properties under ambient conditions owing to their radical character. High electron and hole mobilities up to 10-2 and 10-3 cm2 V-1 s-1 , respectively, were achieved. Xerographic single-layered photoreceptors were fabricated from the radicals studied herein, exhibiting good xerographic photosensitivity across the visible spectrum. PMID- 27706852 TI - Cancer metastasis: Mechanisms of inhibition by melatonin. AB - Melatonin is a naturally occurring molecule secreted by the pineal gland and known as a gatekeeper of circadian clocks. Mounting evidence indicates that melatonin, employing multiple and interrelated mechanisms, exhibits a variety of oncostatic properties in a myriad of tumors during different stages of their progression. Tumor metastasis, which commonly occurs at the late stage, is responsible for the majority of cancer deaths; metastases lead to the development of secondary tumors distant from a primary site. In reference to melatonin, the vast majority of investigations have focused on tumor development and progression at the primary site. Recently, however, interest has shifted toward the role of melatonin on tumor metastases. In this review, we highlight current advances in understanding the molecular mechanisms by which melatonin counteracts tumor metastases, including experimental and clinical observations; emphasis is placed on the impact of both cancer and non-neoplastic cells within the tumor microenvironment. Due to the broad range of melatonin's actions, the mechanisms underlying its ability to interfere with metastases are numerous. These include modulation of cell-cell and cell-matrix interaction, extracellular matrix remodeling by matrix metalloproteinases, cytoskeleton reorganization, epithelial mesenchymal transition, and angiogenesis. The evidence discussed herein will serve as a solid foundation for urging basic and clinical studies on the use of melatonin to understand and control metastatic diseases. PMID- 27706853 TI - Cross-sectional study showed psychosocial variables, gender and family involvement played an important role in an adolescent weight management programme. AB - AIM: This study aimed to investigate the psychosocial gains perceived by overweight adolescents attending a 12-week weight management programme and to analyse gender-specific differences. METHODS: A quantitative cross-sectional study was conducted with a sample of 70 overweight adolescents aged between 12 and 18 (52.9% girls), evaluated at baseline and at week 12 using anthropometric measurements and self-reported questionnaires. We analysed gender-specific differences related to body self-esteem, social life, relationships with their family, physical comfort, health responsibility, perceived benefits of the intervention, self-efficacy and adherence. We further investigated whether the variables at week 12 would predict changes in their body mass index. RESULTS: While weight had a greater impact on the body self-esteem of girls, both at baseline and week 12, boys reported higher self-efficacy and adherence as well as a greater perception of the benefits of the intervention at week 12. The body mass index change was positively associated with body self-esteem, relationships within the family and self-efficacy and adherence. CONCLUSION: Gender specifics and the role of psychosocial variables must be taken into account during weight management programmes for adolescents, and it is important to include the family throughout the entire process. PMID- 27706854 TI - Two different mechanosensitive calcium responses in Muller glial cells of the guinea pig retina: Differential dependence on purinergic receptor signaling. AB - Tractional forces or mechanical stimulation are known to induce calcium responses in retinal glial cells. The aim of the study was to determine the characteristics of calcium responses in Muller glial cells of the avascular guinea pig retina induced by focal mechanical stimulation. Freshly isolated retinal wholemounts were loaded with Mitotracker Deep Red (to fill Muller cells) and the calcium sensitive dye Fluo-4/AM. The inner retinal surface was mechanically stimulated with a micropipette tip for 10 ms. Stimulation induced two different cytosolic calcium responses in Muller cells with different kinetics in dependence on the distance from the stimulation site. Muller cells near the stimulation site displayed an immediate and long-lasting calcium response with high amplitude. This response was mediated by calcium influx from the extracellular space likely triggered by activation of ATP-insensitive P2 receptors. More distant Muller cells displayed, with a delay of 2.4 s, transient calcium responses which propagated laterally in a wave-like fashion. Propagating calcium waves were induced by a calcium-independent release of ATP from Muller cells near the stimulation site, and were mediated by a release of calcium from internal stores triggered by ATP, acting in part at P2Y1 receptors. The data suggest that mechanically stimulated Muller cells of the guinea pig retina release ATP which induces a propagating calcium wave in surrounding Muller cells. Propagating calcium waves may be implicated in the spatial regulation of the neuronal activity and homeostatic glial functions, and may transmit gliosis-inducing signals across the retina. Mechanical stimulation of guinea pig Muller cells induces two calcium responses: an immediate response around the stimulation site and propagating calcium waves. Both responses are differentially mediated by activation of purinergic receptors. GLIA 2016 GLIA 2017;65:62-74.

AB - OBJECTIVE: To explore the potential value of third-trimester combined screening for the prediction of adverse perinatal outcome (APO) in the general population and among small-for-gestational-age (SGA) fetuses. METHODS: This was a nested case-control study within a prospective cohort of 1590 singleton gestations undergoing third-trimester evaluation (32 + 0 to 36 + 6 weeks' gestation). Maternal baseline characteristics, mean arterial blood pressure, fetoplacental ultrasound and circulating biochemical markers (placental growth factor (PlGF), lipocalin-2, unconjugated estriol and inhibin A) were assessed in all women who subsequently had an APO (n = 148) and in a control group without perinatal complications (n = 902). APO was defined as the occurrence of stillbirth, umbilical artery cord blood pH < 7.15, 5-min Apgar score < 7 or emergency operative delivery for fetal distress. Logistic regression models were developed for the prediction of APO in the general population and among SGA cases (defined as customized birth weight < 10th centile). RESULTS: The prevalence of APO was 9.3% in the general population and 27.4% among SGA cases. In the general population, a combined screening model including a-priori risk (maternal characteristics), estimated fetal weight (EFW) centile, umbilical artery pulsatility index (UA-PI), estriol and PlGF achieved a detection rate for APO of 26% (area under receiver-operating characteristics curve (AUC), 0.59 (95% CI, 0.54-0.65)), at a 10% false-positive rate (FPR). Among SGA cases, a model including a-priori risk, EFW centile, UA-PI, cerebroplacental ratio, estriol and PlGF predicted 62% of APO (AUC, 0.86 (95% CI, 0.80-0.92)) at a FPR of 10%. CONCLUSIONS: The use of fetal ultrasound and maternal biochemical markers at 32 36 weeks provides a poor prediction of APO in the general population. Although it remains limited, the performance of the screening model is improved when applied to fetuses with suboptimal fetal growth. Copyright (c) 2016 ISUOG. Published by John Wiley & Sons Ltd. PMID- 27706857 TI - Blood cells serve as a source of factor-inducing rapid ischemic tolerance in brain. AB - Ischemic tolerance (IT) has gained attention as an attractive strategy for improving stroke outcome. Recently, it was shown that signal responsible for rapid IT induction (tolerance induction factor - TIF) is transmitted via circulating blood. In this study, we have hypothesized about the role of the blood cell compartment in TIF production. We used hind-limb ischemia to generate TIF as a rapid preconditioning against transient middle cerebral artery occlusion (MCAO). The essential properties of protein synthesis inhibitors actinomycin D and cycloheximide were utilized to obtain the following results: (i) TIF is proteinaceous. Hind-limb ischemia mediates gene expression followed by translation, resulting in the production of TIF. Blocking of each of these two steps in protein synthesis resulted in rapid infarct evolution (281.5 +/- 23.37 and 330.4 +/- 71.8 mm3 , respectively). (ii) Tourniquet-treated muscle is not a source of TIF. Actinomicine D injected into rat prior to tolerance induction significantly suppressed RNA synthesis in blood cells and muscle tissue. Cross circulation of those rats (donors) with control animals (recipients) did not mediate significant infarct reduction (272.9 +/- 12.45 mm3 ), even when hind-limb ischemia was performed before MCAO in the recipient (223.2 +/- 37.51 mm3 ). (iii) Blood cells serve as a source of TIF. Preischemic transfusion of plasma-free, protein-synthesis-inactive blood cells, which were obtained from tolerant animals did not reduce infarct volume in recipients (131 +/- 16.1 mm3 ) in a range comparable with their protein-synthesis-active counterparts (17.2 +/- 12 mm3 ). We can conclude that blood cells are associated with the induction of rapid IT via production of a bioactive proteinaceous substance. PMID- 27706858 TI - Complications of intrauterine intravascular blood transfusion: lessons learned after 1678 procedures. AB - OBJECTIVE: Maternal alloimmunization to fetal red-blood-cell antigens is a major cause of fetal anemia, which can lead to hydrops and perinatal death if untreated. The cornerstone of management during pregnancy is intrauterine intravascular blood transfusion (IUT). Although this procedure is considered relatively safe, complications continue to occur. The aim of this study was to evaluate rates of procedure-related complications and perinatal loss following IUT, and their change over time, in order to identify factors leading to improved outcome. METHODS: This was a retrospective analysis of all IUTs for red-cell alloimmunization performed at the national referral center for fetal therapy in The Netherlands, from 1988 to 2015. Differences in complication rates and their associations with alterations in transfusion technique after 2001 were assessed. RESULTS: Between 1988 and 2015, 1678 IUTs were performed in 589 fetuses. For IUTs performed in 2001 and onwards, there was significant improvement in survival (88.6% vs 97.0%, P < 0.001) and a decline in procedure-related complications per fetus (9.8% vs 3.3%, P = 0.001) and per procedure (3.4% vs 1.2%, P = 0.003) compared with those performed before 2001. Procedure-related perinatal loss declined from 4.7% to 1.8% per fetus (P = 0.053). Beneficial changes in transfusion technique were routine use of fetal paralysis, increased use of intrahepatic transfusion and avoidance of arterial puncture. CONCLUSIONS: IUT has become an increasingly safe procedure in recent years when performed by experienced hands. The chosen technique should be fine-tuned according to the patient's individual situation. The declining complication rates are most likely related to center volume: this rare procedure is best performed in experienced fetal therapy centers. (c) 2016 Authors.

PMID- 27706859 TI - Diffusion-weighted magnetic resonance imaging of the fetal brain in intrauterine growth restriction. AB - OBJECTIVE: Diffusion-weighted magnetic resonance imaging (DWI) is a sensitive method for assessing brain maturation and detecting brain lesions, providing apparent diffusion coefficient (ADC) values as a measure of water diffusion. Abnormal ADC values are seen in ischemic brain lesions, such as those associated with acute or chronic hypoxia. The aim of this study was to assess whether ADC values in the fetal brain were different in fetuses with severe intrauterine growth restriction (IUGR) compared with normal controls. METHODS: Brain magnetic resonance imaging (MRI) with single-shot axial DWI (b = 0 and b = 700 s/mm2 ) was performed in 30 fetuses with severe IUGR (estimated fetal weight < 3rd centile with absent or reversed umbilical artery Doppler flow) and in 24 normal controls of similar gestational age. Brain morphology and biometry were analyzed. ADC values were measured in frontal and occipital white matter, centrum semiovale, thalami, cerebellar hemisphere and pons. Frontal-occipital and frontal-cerebellar ADC ratios were calculated, and values were compared between IUGR fetuses and controls. RESULTS: There was no difference in gestational age at MRI between IUGR and control fetuses (IUGR, 30.2 +/- 1.6 weeks vs controls, 30.7 +/- 1.4 weeks). Fetal brain morphology and signals were normal in all fetuses. Brain dimensions (supratentorial +/- infratentorial) were decreased (Z-score, < -2) in 20 (66.7%) IUGR fetuses. Compared with controls, IUGR fetuses had significantly lower ADC values in frontal white matter (1.97 +/- 0.23 vs 2.17 +/- 0.22 * 10-3 mm2 /s; P < 0.0001), thalami (1.04 +/- 0.15 vs 1.13 +/- 0.10 *10-3 mm2 /s; P = 0.0002), centrum semiovale (1.86 +/- 0.22 vs 1.97 +/- 0.23 *10-3 mm2 /s; P = 0.01) and pons (0.85 +/- 0.19 vs 0.94 +/- 0.12 *10-3 mm2 /s; P = 0.043). IUGR fetuses had a lower frontal-occipital ADC ratio than did normal fetuses (1.00 +/- 0.11 vs 1.08 +/- 0.05; P = 0.003). CONCLUSIONS: ADC values in IUGR fetuses were significantly lower than in normal controls in the frontal white matter, thalami, centrum semiovale and pons, suggesting abnormal maturation in these regions. However, the prognostic value of these ADC changes is still unknown. Copyright (c) 2016 ISUOG. Published by John Wiley & Sons Ltd. PMID- 27706860 TI - Visuomotor signals for reaching movements in the rostro-dorsal sector of the monkey thalamic reticular nucleus. AB - The thalamic reticular nucleus (TRN) collects inputs from the cerebral cortex and thalamus and, in turn, sends inhibitory outputs to the thalamic relay nuclei. This unique connectivity suggests that the TRN plays a pivotal role in regulating information flow through the thalamus. Here, we analyzed the roles of TRN neurons in visually guided reaching movements. We first used retrograde transneuronal labeling with rabies virus, and showed that the rostro-dorsal sector of the TRN (TRNrd) projected disynaptically to the ventral premotor cortex (PMv). In other experiments, we recorded neurons from the TRNrd or PMv while monkeys performed a visuomotor task. We found that neurons in the TRNrd and PMv showed visual-, set-, and movement-related activity modulation. These results indicate that the TRNrd, as well as the PMv, is involved in the reception of visual signals and in the preparation and execution of reaching movements. The fraction of neurons that were non-selective for the location of visual signals or the direction of reaching movements was greater in the TRNrd than in the PMv. Furthermore, the fraction of neurons whose activity increased from the baseline was greater in the TRNrd than in the PMv. The timing of activity modulation of visual-related and movement-related neurons was similar in TRNrd and PMv neurons. Overall, our data suggest that TRNrd neurons provide motor thalamic nuclei with inhibitory inputs that are predominantly devoid of spatial selectivity, and that these signals modulate how these nuclei engage in both sensory processing and motor output during visually guided reaching behavior.

AB - Treatment of nonaromatic N-fused [24]pentaphyrin with trichloromethylsilane in the presence of a base afforded doubly N-fused [24]pentaphyrin and its silicon complex. Addition of fluoride ion to the silicon complex led to the formation of its fluorosilicate as an unprecedented monoanionic six-coordinated SiIV complex of porphyrinoid. Treatment of the fluorosilicate with acid led to the recovery of the silicon complex. The doubly N-fused pentaphyrin, the silicon complex, and the fluorosilicate were all characterized as distinct Mobius aromatic molecules by spectroscopic measurements and X-ray crystallographic analyses. Importantly, the second N-fusion reaction, Si-incorporation and fluoride addition to the Si-atom enhanced the aromaticity of doubly N-fused [24]pentaphyrins in this order. Tamao Fleming oxidation of the silicon complex gave beta-keto doubly N-fused pentaphyrin and triply fused [24]pentaphyrin, which were nonaromatic and Huckel anti-aromatic, respectively.

AB - RATIONALE: Nicotine and cotinine are, respectively, alkaloids produced mainly by the Solanaceae plant family, especially tobacco, and its most important human metabolite. These compounds are frequently found as contaminants in wastewater or landfill samples and they could be used to evaluate pollution by tobacco use. The aim of this study is to improve the knowledge about possible transformation pathways of nicotine and cotinine. This would help the identification of degradants by using HPLC coupled with a high resolving power mass analyzer (LTQ Orbitrap). In addition, we evaluated toxicity on bioluminescent photobacteria to indicate possible relationships between the formation of transformation products and their toxic effects. METHODS: The transformation of nicotine and cotinine and the formation of intermediate products were evaluated adopting titanium dioxide as photocatalyst. The structural identification of photocatalytic transformation products of these two alkaloids was based on LC/multistage MS experiments. High resolution MS allowed the elemental composition of these products to be hypothesized. The evolution of toxicity as a function of the irradiation time was also studied using a bioluminescent photobacterium (Vibrio fischeri) test. RESULTS: Several products were formed and characterized using HPLC/HRMSn . The main photocatalytic pathways involving nicotine and cotinine appear to be hydroxylation, demethylation and oxidation. Nine degradants were formed from nicotine, including cotinine. Seven degradants were generated from cotinine. There is no transformation product in common between the two studied molecules. CONCLUSIONS: The study of photocatalytic degradation allowed us to partially simulate human metabolism and the environmental transformation of the bioactive alkaloid nicotine. We searched for some of the identified transformation products in river water and landfill percolate by solid-phase extraction and HPLC/HRMS and eventually their presence was confirmed. These new findings could be of interest in further metabolism and environmental pollution studies. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27706864 TI - Maternal cardiac function at 35-37 weeks' gestation: relationship with birth weight. AB - OBJECTIVE: To evaluate the relationship between maternal cardiovascular parameters and neonatal birth weight and examine the potential value of these parameters in improving the prediction of small-for-gestational-age (SGA) and large-for-gestational-age (LGA) neonates provided by maternal characteristics and medical history. METHODS: In 2835 singleton pregnancies maternal characteristics and medical history were recorded and maternal cardiovascular parameters were measured. The observed measurements of cardiovascular parameters were expressed as multiples of the normal median (MoM) values after adjustment for those characteristics found to provide a substantial contribution to their measurement. Regression analysis was used to determine the significance of association between the normalized values of the cardiovascular parameters with birth-weight Z-score. Multivariable logistic regression analysis was then used to determine if the maternal factors, fetal biometry and maternal cardiovascular parameters had a significant contribution to predicting SGA and LGA neonates. The performance of screening was determined by the area under receiver-operating characteristics curves (AUC). RESULTS: In the study population there were significant positive associations between maternal cardiac output and heart rate with neonatal birth weight Z-score, and significant negative associations between total peripheral resistance and mean arterial pressure (MAP) with neonatal birth-weight Z-score. In pregnancies delivering SGA neonates (n = 249 (8.8%)), cardiac output and heart rate were lower and total peripheral resistance and MAP were higher, whereas in pregnancies delivering LGA neonates (n = 292 (10.3%)) cardiac output and heart rate were higher and total peripheral resistance and MAP were lower. The performance of screening for delivery of SGA neonates achieved by maternal characteristics and fetal biometry was not improved by the measurement of maternal cardiovascular parameters. There was a small but significant improvement in the performance of screening for delivery of LGA neonates by maternal factors and fetal biometry with the addition of maternal heart rate (comparison of AUC, P = 0.0095). CONCLUSIONS: There are significant associations between maternal cardiac output, heart rate, total peripheral resistance and MAP and neonatal birth-weight Z-score; such findings reflect the close relationship between maternal cardiac function and fetal demands. However, assessment of these parameters at 35-37 weeks' gestation is unlikely to improve substantially the performance of screening for SGA or LGA neonates provided by a combination of maternal factors and fetal biometry.

AB - PURPOSE: To describe the occlusal pressure redistribution in dental arches following placement of single posterior implant-supported restorations in occlusion with natural dentitions. MATERIALS AND METHODS: Fifteen patients who presented for successfully osseointegrated single posterior implant restorations participated in the study. Cement-retained, all-ceramic implant crowns were fabricated and delivered after adjustment for interproximal contacts, fit, and uniform occlusal contacts. Occlusal pressure distribution was recorded with a digital sensor that reported contact point forces as a percentage of total pressure applied to the sensor. Measurements were taken before and after restoration for comparison. The distribution of relative occlusal stress was analyzed for statistical significance by location. RESULTS: The results indicated that placement of posterior implant-supported restorations increased the bite pressure in the sextants containing the restorations by an average of 4.18% (p = 0.019) of the maximum value registered (maximum bite pressure). The contralateral occlusal load was found to decrease by 2.9% (p = 0.047) of the maximum value registered; however, there was no significant difference among or between the tooth positions. CONCLUSION: Single posterior implant-supported restorations significantly increased the percentage (%) of total occlusal pressure in the containing sextant and decreased percentage of total occlusal pressure in the contralateral sextant. When analyzing restorations by exact position, more posterior implant restorations decreased the occlusal pressure applied in anterior dentitions. PMID- 27706866 TI - Genetic basis for variation in salinity tolerance between stickleback ecotypes. AB - Adaptation to different salinities can drive and maintain divergence between populations of aquatic organisms. Anadromous and stream ecotypes of threespine stickleback (Gasterosteus aculeatus) are an excellent model to explore the genetic mechanisms underlying osmoregulation divergence. Using a parapatric pair of anadromous and stream stickleback ecotypes, we employed an integrated genomic approach to identify candidate genes important for adaptation to different salinity environments. Quantitative trait loci (QTL) mapping of plasma sodium concentrations under a seawater challenge experiment identified a significant QTL on chromosome 16. To identify candidate genes within this QTL, we first conducted RNA-seq and microarray analysis on gill tissue to find ecotypic differences in gene expression that were associated with plasma Na+ levels. This resulted in the identification of ten candidate genes. Quantitative PCR analysis on gill tissue of additional Japanese stickleback populations revealed that the majority of the candidate genes showed parallel divergence in expression levels. Second, we conducted whole-genome sequencing and found five genes that are predicted to have functionally important amino acid substitutions. Finally, we conducted genome scan analysis and found that eight of these candidate genes were located in genomic islands of high differentiation, suggesting that they may be under divergent selection. The candidate genes included those involved in ATP synthesis and hormonal signalling, whose expression or amino acid changes may underlie the variation in salinity tolerance. Further functional molecular analysis of these genes will reveal the causative genetic and genomic changes underlying divergent adaptation. PMID- 27706867 TI - Prevalence and risk factors associated with hardcore smoking among rural daily male smokers. AB - BACKGROUND AND OBJECTIVES: The existence of smokers who are resistant to smoking cessation interventions has attracted considerable interest in recent years. Given the paucity of data on that topic in rural China, we aimed to assess the prevalence and risk factors of hardcore smoking in rural China. METHODS: A cross sectional study was conducted in 14 villages in Shandong, China. A total of 1,287 male daily smokers were face-to-face interviewed. A multiple logistic regression model was used to explore the associations of demographics, environment, knowledge and attitudes about smoking, and smoking behavior characteristics with hardcore smoking among daily male smokers. A general dominance analysis model was used to access the relative contribution of the determinants that were identified in the multiple logistic regression. RESULTS: Hardcore smokers constituted 32.9% (n = 423) of daily male smokers. Five determinants for hardcore smoking were identified in the multiple logistic regression. Dominance analysis showed higher level of smoking intensity was the most important determinant of hardcore smoking, followed by being a farmer, starting to smoke daily under the age of 20, younger age, having fewer smokers around. DISCUSSION AND CONCLUSIONS: This study suggests that hardcore smokers account for a substantial proportion of daily male smokers and are distinct from other groups of daily smokers. SCIENTIFIC SIGNIFICANCE: Specifically tailored tobacco-control efforts should be made to address the issues incurred by hardcore smokers. (Am J Addict 2016;25:628-633). PMID- 27706868 TI - Synaptic pathology in the cerebellar dentate nucleus in chronic multiple sclerosis. AB - In multiple sclerosis, cerebellar symptoms are associated with clinical impairment and an increased likelihood of progressive course. Cortical atrophy and synaptic dysfunction play a prominent role in cerebellar pathology and although the dentate nucleus is a predilection site for lesion development, structural synaptic changes in this region remain largely unexplored. Moreover, the mechanisms leading to synaptic dysfunction have not yet been investigated at an ultrastructural level in multiple sclerosis. Here, we report on synaptic changes of dentate nuclei in post-mortem cerebella of 16 multiple sclerosis patients and eight controls at the histological level as well as an electron microscopy evaluation of afferent synapses of the cerebellar dentate and pontine nuclei of one multiple sclerosis patient and one control. We found a significant reduction of afferent dentate synapses in multiple sclerosis, irrespective of the presence of demyelination, and a close relationship between glial processes and dentate synapses. Ultrastructurally, we show autophagosomes containing degradation products of synaptic vesicles within dendrites, residual bodies within intact-appearing axons and free postsynaptic densities opposed to astrocytic appendages. Our study demonstrates loss of dentate afferent synapses and provides, for the first time, ultrastructural evidence pointing towards neuron-autonomous and neuroglia-mediated mechanisms of synaptic degradation in chronic multiple sclerosis. PMID- 27706869 TI - Myocardial infarction, patient decision delay and help-seeking behaviour: a thematic analysis. AB - AIMS AND OBJECTIVES: To explore patient decision delay, the symptom experience and factors that motivated the patient experiencing myocardial infarction to go to the emergency department. BACKGROUND: Reperfusion for myocardial infarction is more effective if performed as soon as possible after the onset of symptoms. Multiple studies show that prehospital delay is long and can average several hours. DESIGN: A qualitative descriptive design using semi-structured interviews. METHODS: All consecutive myocardial infarction patients who between July 2013 January 2014 at a single-centre metropolitan tertiary hospital in Western Australia were included. Patient responses to an open-ended question were recorded and transcribed verbatim. Data were analysed using Braun & Clarke (Qual Res Psychol, 3, 2006, 77-101) thematic analysis method. RESULTS: Of the 367 eligible, 255 provided consent. Three themes emerged from the qualitative analyses: (1) onset and response to symptoms, and this included three subthemes: context of the event, diversity of symptom interpretation and response to symptoms; (2) help-seeking behaviour, and this included the patient seeking help from various lay and professional sources; and (3) help-seeking outcomes, which include calling the emergency ambulance, going to emergency department, seeing a general practitioner, seeing a general practitioner who advised them to go home. CONCLUSION: The context of the event, their symptomatology and the layperson who was the first point of contact influenced the decision for the patient to go to the emergency department. Many patients used private transport or contacted their general practitioner. New knowledge from this study emphasises the importance of the layperson understanding the appropriate response is to seek prompt care through immediate emergency transport by ambulance to emergency department. RELEVANCE TO CLINICAL PRACTICE: This study highlights the need to educate both the patient and the wider public, not only to seek prompt care but to also to call the emergency ambulance to arrange transport to the emergency department. PMID- 27706870 TI - Mass spectrometric monitoring of oxidation of aliphatic C6-C8 hydrocarbons and ethanol in low pressure oxygen and air plasmas. AB - Experimental and theoretical studies on the oxidation of saturated hydrocarbons (n-hexane, cyclohexane, n-heptane, n-octane and isooctane) and ethanol in 28 Torr O2 or air plasma generated by a hollow cathode discharge ion source were made. Ions corresponding to [M + 15]+ and [M + 13]+ in addition to [M - H]+ and [M - 3H]+ were detected as major ions where M is the sample molecule. The ions [M + 15]+ and [M + 13]+ were assigned as oxidation products, [M - H + O]+ and [M - 3H + O]+ , respectively. By the tandem mass spectrometry analysis of [M - H + O]+ and [M - 3H + O]+ , H2 O, olefins (and/or cycloalkanes) and oxygen-containing compounds were eliminated from these ions. Ozone as one of the terminal products in the O2 plasma was postulated as the oxidizing reagent. As an example, the reactions of C6 H14+* with O2 and of C6 H13+ (CH3 CH2 CH+ CH2 CH2 CH3 ) with ozone were examined by density functional theory calculations. Nucleophilic interaction of ozone with C6 H13+ leads to the formation of protonated ketone, CH3 CH2 C(=OH+ )CH2 CH2 CH3 . In air plasma, [M - H + O]+ became predominant over carbocations, [M - H]+ and [M - 3H]+ . For ethanol, the protonated acetic acid CH3 C(OH)2+ (m/z 61.03) was formed as the oxidation product. The peaks at m/z 75.04 and 75.08 are assigned as protonated ethyl formate and protonated diethyl ether, respectively, and that at m/z 89.06 as protonated ethyl acetate.

AB - AIMS AND OBJECTIVES: To explore the issues and challenges of care transitions in the preoperative environment. BACKGROUND: Ineffective transitions play a role in a majority of serious medical errors. There is a paucity of research related to the preoperative arena and the multiple inherent transitions in care that occur there. DESIGN: Qualitative descriptive design was used. METHODS: Semistructured interviews were conducted in a 975-bed academic medical centre. RESULTS: A total of 30 providers and 10 preoperative patients participated. Themes that arose were as follows: (1) need for clarity of purpose of preoperative care, (2) care coordination, (3) interprofessional boundaries of care and (4) inadequate time and resources. CONCLUSION: Effective transitions in the preoperative environment require that providers bridge scope of practice barriers to promote good teamwork. Preoperative care that is a product of well-informed providers and patients can improve the entire perioperative care process and potentially influence postoperative patient outcomes. RELEVANCE TO CLINICAL PRACTICE: Nurses are well positioned to bridge the gaps within transitions of care and accordingly affect health outcomes.

PMID- 27706874 TI - Confronting one's vulnerability - patients with chest pain participating in a high-intensity exercise programme. AB - AIMS AND OBJECTIVES: To explain the transitional process that individuals with unexplained chest pain undergo while participating in an exercise training programme over time. BACKGROUND: Angina-like chest pain in patients with no obstructive coronary artery disease is a growing problem. Functional limitations, restricted daily activities and reduced quality of life are reported. In addition, physical activity is avoided in this population. DESIGN: The study follows a qualitative classic grounded theory (Glaser ). METHODS: Three times a week for 12 weeks, twelve patients with no obstructive coronary artery disease participated in a high-intensity aerobic exercise training programme supervised by physiotherapists and nurses. The data collection was based on diaries and interviews about the experience and analysed according to the principles of classic grounded theory. RESULTS: The core category was identified as 'confronting one's vulnerability' and included three subcategories: 'balancing existential uncertainty', 'transforming bodily perceptions' and 'becoming a more capable person'. CONCLUSION: The transition was described as a process of becoming more capable. Health professionals should be aware of the significance of high-intensity exercise training for people with unexplained chest pain and of the underlying dimension of vulnerability. RELEVANCE TO CLINICAL PRACTICE: Understanding the transition process that people with unexplained chest pain undergo while participating in a high-intensity exercise training programme promotes a person-centred approach. Taking this substantive theory into consideration will improve the prerequisites for establishing person-centred care. PMID- 27706875 TI - Patient perspectives on answering questions about sexual orientation and gender identity: an integrative review. AB - AIMS AND OBJECTIVES: To examine patients' perceptions of being asked about their sexual orientation and gender identity in the healthcare setting. BACKGROUND: Health disparities exist in the lesbian, gay, bisexual and transgender population, but further research is needed to better understand these disparities. To address this issue, experts recommend the routine collection of sexual orientation and gender identity data in health care. Nurses on the front line of patient care play a key role in the collection of these data. However, to enable nurses to conduct such assessments it is important to understand the perspective of the patients on being asked about their sexual orientation and gender identity in a healthcare setting. DESIGN: An integrative review was conducted using the methodology proposed by Whittemore and Knafl (Journal of Advanced Nursing, 2005, 52, 546). METHODS: Six electronic databases were searched, and two reviewers independently reviewed papers for inclusion. Papers were included if they were empirical studies, peer-reviewed papers or reports, assessing patient perspectives on discussing sexual orientation and gender identity in the healthcare setting. RESULTS: Twenty-one relevant studies that met the inclusion criteria were identified. A majority of the studies indicated patients' willingness to respond to, and a perceived importance of, questions about sexual orientation and gender identity. However, fears of homophobia and negative consequences hindered willingness to disclose this information. CONCLUSIONS: This review indicates that in most cases patients are willing to answer routine questions about their sexual orientation in the healthcare setting and perceive them as important questions to ask. RELEVANCE TO CLINICAL PRACTICE: The findings of this review have implications for nurses looking to incorporate questions about sexual orientation into their routine patient assessment. The findings indicate that care providers need to be mindful of heteronormative assumptions and take steps to ensure they are knowledgeable about lesbian, gay, bisexual and transgender health. PMID- 27706876 TI - What is the existing evidence supporting the efficacy of compression bandage systems containing both elastic and inelastic components (mixed-component systems)? A systematic review. AB - AIMS AND OBJECTIVES: To analyse current evidence on the efficacy of bandage systems containing both elastic and inelastic components (mixed-component systems). BACKGROUND: International consensus on the efficacy of types of compression systems is difficult to achieve; however, mixed-component systems are being promoted as combining the best properties of both elastic and inelastic bandage systems and increasingly being used to treat venous leg ulcers in practice. DESIGN: A systematic literature review. METHODS: Search terms such as venous leg ulcer, varicose ulcer, leg ulcer, compression, bandage, elastic, inelastic, short stretch, healing rate, interface pressure, mixed component, two layer, four-layer and multi-layer were used in database and hand searches in several combinations. Limits were set for years 2005-March 2015 and English language publications. RESULTS: A total of 475 studies were identified at initial search, and following elimination from abstract and title, this was reduced to 7. A further study was identified on Google Scholar, bringing the final number of studies fitting inclusion criteria to 8. The following subgroups relating to outcomes of efficacy were identified: ulcer healing, maintenance of interface pressure, slippage, ease of application and patient quality of life. CONCLUSIONS: Mixed-component systems were found to have comparable ulcer healing rates to alternative compression systems and be easy to apply; have similar abilities to maintain pressure as four-layer bandages and better abilities than short-stretch bandages; have less slippage than alternative systems; and to be significantly associated with several favourable quality of life outcomes. Clinician skill in bandage application was an uncontrolled variable in all eight papers included in the review, which may limit reliability of findings. RELEVANCE TO CLINICAL PRACTICE: This review synthesises existing evidence on the efficacy of mixed component systems and encourages clinicians to regard them as an effective alternative to purely elastic or inelastic compression systems. Additionally, it highlights the importance of clinician skill in bandage application as a crucial determinant of effective compression.

AB - BACKGROUND: Auditory hypersensitivity is one of the major complications in autism spectrum disorder. The aim of this study was to investigate whether the auditory brain center is affected in autism model rats. METHODS: Autism model rats were prepared by prenatal exposure to thalidomide on embryonic day 9 and 10 in pregnant rats. The superior olivary complex (SOC), a complex of auditory nuclei, was immunostained with anti-calbindin d28k antibody at postnatal day 50. RESULTS: In autism model rats, SOC immunoreactivity was markedly decreased. Strength of immunostaining of SOC auditory fibers was also weak in autism model rats. Surprisingly, the size of the medial nucleus of trapezoid body, a nucleus exerting inhibitory function in SOC, was significantly decreased in autism model rats. CONCLUSIONS: Auditory hypersensitivity may be, in part, due to impairment of inhibitory processing by the auditory brain center. PMID- 27706878 TI - Medication communication between nurses and doctors for paediatric acute care: An ethnographic study. AB - AIMS AND OBJECTIVES: To examine how communication between nurses and doctors occurred for managing medications in inpatient paediatric settings. BACKGROUND: Communication between health professionals influences medication incidents' occurrence and safe care. DESIGN: An ethnographic study was undertaken. METHODS: Semi-structured interviews, observations and focus groups were conducted in three clinical areas of an Australian tertiary paediatric hospital. Data were transcribed verbatim and thematically analysed using the Medication Communication Model. RESULTS: The actual communication act revealed health professionals' commitment to effective medication management and the influence of professional identities on medication communication. Nurses and doctors were dedicated to providing safe, effective medication therapy for children, within their scope of practice and perceived role responsibilities. Most nurses and junior doctors used tentative language in their communication while senior doctors tended to use direct language. Irrespective of language style, nurses actively engaged with doctors to promote patients' needs. Yet, the medical hierarchical structure, staffing and attendant expectations influenced communication for medication management, causing frustration among nurses and doctors. Doctors' lack of verbal communication of documented changes to medication orders particularly troubled nurses. Nurses persisted in their efforts to acquire appropriate orders for safe medication administration to paediatric patients. CONCLUSIONS: Collaborative practice between nurses and doctors involved complex, symbiotic relationships. Their dedication to providing safe medication therapy to paediatric patients facilitated effective medication management. At times, shortcomings in interdisciplinary communication impacted on potential and actual medication incidents. RELEVANCE TO CLINICAL PRACTICE: Understanding of the complexities affecting medication communication between nurses and doctors helps to ensure interprofessional respect for each other's roles and inherent demands. Interdisciplinary education delivered in healthcare organisations would facilitate greater clarity in communication related to medications. Encouraging the use of concise, clear words in communication would help to promote improved understanding between parties, and accuracy and efficacy of medication management. PMID- 27706880 TI - Genetic-Algorithm-Based Optimization of a Peptidic Scaffold for Sequestration and Hydration of CO2. AB - Biomimicry is a strategy that makes practical use of evolution to find efficient and sustainable ways to produce chemical compounds or engineer products. Exploring the natural machinery of enzymes for the production of desired compounds is a highly profitable investment, but the design of efficient biomimetic systems remains a considerable challenge. An ideal biomimetic system self-assembles in solution, binds a desired range of substrates and catalyzes reactions with turnover rates similar to the native system. To this end, tailoring catalytic functionality in engineered peptides generally requires site directed mutagenesis or the insertion of additional amino acids, which entails an intensive search across chemical and sequence space. Here we discuss a novel strategy for the computational design of biomimetic compounds and processes that consists of a) characterization of the wild-type and biomimetic systems; b) identification of key descriptors for optimization; c) an efficient search through sequence and chemical space to tailor the catalytic capabilities of the biomimetic system. Through this proof-of-principle study, we are able to decisively understand and identify whether a given scaffold is useful, appropriate and tailorable for a given, desired task. PMID- 27706879 TI - Acute kidney injury post-major orthopaedic surgery: A single-Centre case-control study. AB - AIM: To identify risk factors for acute kidney injury following major orthopaedic surgery. METHODS: We included all patients undergoing major orthopaedic surgery at University Hospital Geelong between 2008 and 2014 in the study. Out of 2188 surgeries audited, we identified cases of acute kidney injury using the RIFLE criteria and matched those to controls 2:1 for age, sex, procedure and chronic kidney disease stage. We reviewed their records for risk factors of postoperative acute kidney injury, including medications such as gentamicin, diuretics, non steroidal anti-inflammatory drugs and angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use. We reviewed the patients' history of cardiovascular disease, chronic liver disease, hypertension and diabetes mellitus along with presence of sepsis and obesity. Associations of hypothetical risk factors were estimated using conditional logistic regression. RESULTS: We identified 164 cases of AKI in an elderly cohort (median age = 73 years). Controlling for baseline comorbidities, both diuretic and angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use were found to be associated with a twofold risk of acute kidney injury (diuretic - OR 2.06 95% CI:1.30-3.26, P < 0.005, angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use OR 2.09 95% CI:1.31-3.32, P < 0.005). A dose-effect model accounting for perioperative nonsteroidal anti-inflammatory drug administration demonstrated a linear relationship between the number of times these drugs were given and postoperative acute kidney injury risk (OR 1.35 95% CI:1.05-1.73, P = 0.02). CONCLUSIONS: We identified perioperative diuretics, non-steroidal anti inflammatory drugs and angiotensin-converting enzyme inhibitor or angiotensin receptor blocker to be significantly associated with postoperative AKI. Further prospective studies are required to confirm this. PMID- 27706881 TI - Efficient and non-toxic gene delivery by anionic lipoplexes based on polyprenyl ammonium salts and their effects on cell physiology. AB - BACKGROUND: One of the major challenges limiting the development of gene therapy is an absence of efficient and safe gene carriers. Among the nonviral gene delivery methods, lipofection is considered as one of the most promising. In the present study, a set of cationic polyprenyl derivatives [trimethylpolyprenylammonium iodides (PTAI)] with different lengths of polyprenyl chains (from 7, 8 and 11 to 15 isoprene units) was suggested as a component of efficient DNA vehicles. METHODS: Optimization studies were conducted for PTAI in combination with co-lipid dioleoylphosphatidylethanolamine on DU145 human prostate cancer cells using: size and zeta potential measurements, confocal microscopy, the fluorescein diacetate/ethidium bromide test, cell counting, time lapse monitoring of cell movement, gap junctional intercellular coupling analysis, antimicrobial activity assay and a red blood cell hemolysis test. RESULTS: The results obtained show that the lipofecting activity of PTAI allows effective transfection of plasmid DNA complexed in negatively-charged lipoplexes of 200-500 nm size into cells without significant side effects on cell physiology (viability, proliferation, morphology, migration and gap junctional intercellular coupling). Moreover, PTAI-based vehicles exhibit a potent bactericidal activity against Staphylococcus aureus and Escherichia coli. The developed anionic lipoplexes are safe towards human red blood cell membranes, which are not disrupted in their presence. CONCLUSIONS: The developed carriers constitute a group of promising lipofecting agents of a new type that can be utilized as effective lipofecting agents in vitro and they are also an encouraging basis for in vivo applications. PMID- 27706882 TI - Fecal retention in childhood: Evaluation on ultrasonography. AB - BACKGROUND: To assess the usefulness of rectal diameter measurement on ultrasonography as a diagnostic tool for fecal retention in children. METHODS: One hundred children (median age, 5.0 years), consisting of 80 with functional constipation and 20 without constipation, participated in the study. All patients underwent physical examination that included digital rectal examination. Forty five children underwent ultrasonography in three differential planes: transection above the symphysis; under the ischial spine; and at the bladder neck. The measurement of the rectal diameter at the transection above the symphysis could most easily detect fecal retention and had the closest correlations with retention among the three planes. RESULTS: Rectal diameter was wider at all measuring points (35.2 vs 20.9 mm above the symphysis, P < 0.0001; 35.7 vs 24.0 mm under the ischial spine, P < 0.0001; and 19.4 vs 8.7 mm at the bladder neck, P < 0.0001) in children with fecal retention than in those with no fecal retention. With regard to presence of constipation, children with fecal retention had a wider rectal diameter above the symphysis than those with no fecal retention (children with functional constipation, 35.3 vs 20.0 mm, P < 0.0001; children without constipation: 32.6 vs 14.6 mm, P = 0.0026). The cut-off for the rectal diameter measured above the symphysis to identify fecal retention was 27 mm, with high sensitivity and specificity (95.5% and 94.1%, respectively). CONCLUSION: Ultrasound rectal diameter measurement can be used to detect fecal retention in children. PMID- 27706884 TI - Optimisation of combi-lipases from Aspergillus niger for the synergistic and efficient hydrolysis of soybean oil. AB - The enzymatic properties of four lipases (A, B, C and D) from different strains of Aspergillus niger, were investigated, and a 3-factor mixture design and triangular surface analysis were performed to screen the optimal combi-lipase by observing synergistic effects. Lipases B and D differed in optimal pH, temperature and substrate specificity. A combi-lipase with 31.2% lipase B and 68.8% lipase D (w/w, equal to units of 30.36% and 69.64%) exhibited optimal hydrolytic activity on soybean oil, which exceeded the sum of the combined activities of individual lipases (P < 0.05). Free fatty acid from the hydrolyzed soybean oil indicated that the synergistic effect of the combi-lipase resulted from the different fatty acid specificities of the two lipases. Overall, combi lipase afforded an effective route for the application of lipase enzymes to animal feeds. PMID- 27706883 TI - Genome-wide sequence data suggest the possibility of pollinator sharing by host shift in dioecious figs (Moraceae, Ficus). AB - The obligate mutualism of figs and fig-pollinating wasps has been one of the classic models used for testing theories of co-evolution and cospeciation due to the high species-specificity of these relationships. To investigate the species specificity between figs and fig pollinators and to further understand the speciation process in obligate mutualisms, we examined the genetic differentiation and phylogenetic relationships of four closely related fig pollinating wasp species (Blastophaga nipponica, Blastophaga taiwanensis, Blastophaga tannoensis and Blastophaga yeni) in Japan and Taiwan using genome wide sequence data, including mitochondrial DNA sequences. In addition, population structure was analysed for the fig wasps and their host species using microsatellite data. The results suggest that the three Taiwanese fig wasp species are a single panmictic population that pollinates three dioecious fig species, which are sympatrically distributed, have large differences in morphology and ecology and are also genetically differentiated. Our results illustrate the first case of pollinator sharing by host shift in the subgenus Ficus. On the other hand, there are strict genetic codivergences between allopatric populations of the two host-pollinator pairs. The possible processes that produce these pollinator-sharing events are discussed based on the level and pattern of genetic differentiation in these figs and fig wasps. PMID- 27706885 TI - Patterns of the co-use of alcohol, marijuana, and emerging tobacco products in a national sample of young adults. AB - BACKGROUND: Emerging tobacco product use is on the rise in young adults and has been linked to alcohol and marijuana use. Little is known about which patterns of alcohol, marijuana, and emerging tobacco product co-use are most popular in this age group. OBJECTIVES: This study examined the prevalence of a broad spectrum of marijuana, alcohol, and tobacco co-use patterns across a variety of tobacco products in a national sample of young adults. METHODS: Data were analyzed from a sub-set of 18-24 year olds (unweighted n = 3,940) from five waves of the Truth Initiative Young Adult Cohort, a national sample of 18-34 year olds. A user generated statistical program in R was used to assess all possible patterns of past 30-day use of alcohol, marijuana, cigarettes, cigars, e-cigarettes, little cigars/cigarillos, hookah, and other tobacco (pipe, chew, dip, snus, dissolvables). RESULTS: No past 30-day use of any substance emerged as the most popular pattern across all years (42%), followed by exclusive past 30-day alcohol use (31%), and past 30-day alcohol use with cigarettes (5%) or marijuana (4%). The popularity of exclusive marijuana use increased over time, but only 1% reported exclusive marijuana use without the combination of either alcohol or a tobacco product. E-cigarette use only emerged in combination with alcohol and was the least popular pattern of co-use relative to other patterns. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Patterns stress the importance of alcohol among young people. Successful substance use prevention should focus on alcohol's co-use with a variety of substances of abuse, rather than focus on a single behavior. (Am J Addict 2016;25:634-640). PMID- 27706886 TI - Study of Predatory Open Access Nursing Journals. AB - PURPOSE: The purpose of this study was to identify predatory journals in nursing, describe their characteristics and editorial standards, and document experiences of authors, peer reviewers, and editors affiliated with these journals. DESIGN: Using two sources that list predatory journals, the research team created a list of nursing journals. In Phase One, the team collected data on characteristics of predatory nursing journals such as types of articles published, article processing charge, and peer review process. In Phase Two, the team surveyed a sample of authors, reviewers, and editors to learn more about their experiences with their affiliated journals. METHODS: Data from the review of predatory nursing journals were analyzed using descriptive statistics. Written comments were summarized and categorized. FINDINGS: There were 140 predatory nursing journals from 75 publishers. Most journals were new, having been inaugurated in the past 1 to 2 years. One important finding was that many journals only published one or two volumes and then either ceased publishing or published fewer issues and articles after the first volume. Journal content varied widely, and some journals published content from dentistry and medicine, as well as nursing. Qualitative findings from the surveys confirmed previously published anecdotal evidence, including authors selecting journals based on spam emails and inability to halt publication of a manuscript, despite authors' requests to do so. CONCLUSIONS: Predatory journals exist in nursing and bring with them many of the "red flags" that have been noted in the literature, including lack of transparency about editorial processes and misleading information promoted on websites. The number of journals is high enough to warrant concern in the discipline about erosion of our scholarly literature. CLINICAL RELEVANCE: Nurses rely on the published literature to provide evidence for high-quality, safe care that promotes optimal patient outcomes. Research published in journals that do not adhere to the highest standards of publishing excellence have the potential to compromise nursing scholarship and is an area of concern. PMID- 27706887 TI - Increased mitochondrial fusion in a autosomal recessive CMT2A family with mitochondrial GTPase mitofusin 2 mutations. AB - Charcot-Marie-Tooth type 2A disease (CMT2A) is an inherited peripheral neuropathy mainly caused by mutations in the MFN2 gene coding for the mitochondrial fusion protein mitofusin 2. Although the disease is mainly inherited in a dominant fashion, few cases of early-onset autosomal recessive CMT2A (AR-CMT2A) have been reported in recent years. In this study, we characterized the structure of the mitochondrial network in cultured primary fibroblasts obtained from AR-CMT2A family members. The patient-derived cells showed an increase of the mitochondrial fusion with large connected networks and an increase of the mitochondrial volume. Interestingly, fibroblasts derived from the two asymptomatic parents showed similar changes to a lesser extent. These results support the hypothesis that AR CMT2A-related MFN2 mutations acts through a semi-dominant negative mechanism and suggest that other biological parameters might show mild alterations in asymptomatic heterozygote AR-CMT2A patients. Such alterations could be useful biomarkers helping to distinguish MFN2 mutations from variants, a growing challenge with the advent of next generation sequencing into routine clinical practice. PMID- 27706889 TI - Design, Synthesis, and Application of an Optimized Monofluorinated Aliphatic Label for Peptide Studies by Solid-State 19 F NMR Spectroscopy. AB - A conformationally restricted monofluorinated alpha-amino acid, (3 fluorobicyclo[1.1.1]pentyl)glycine (F-Bpg), was designed as a label for the structural analysis of membrane-bound peptides by solid-state 19 F NMR spectroscopy. The compound was synthesized and validated as a 19 F label for replacing natural aliphatic alpha-amino acids. Calculations suggested that F-Bpg is similar to Leu/Ile in terms of size and lipophilicity. The 19 F NMR label was incorporated into the membrane-active antimicrobial peptide PGLa and provided information on the structure of the peptide in a lipid bilayer. PMID- 27706888 TI - On the interpretation of electron microscopic maps of biological macromolecules. AB - The images of flash-frozen biological macromolecules produced by cryo-electron microscopy (EM) can be used to generate accurate, three-dimensional, electric potential maps for these molecules that resemble X-ray-derived electron density maps. However, unlike electron density maps, electric potential maps can include negative features that might for example represent the negatively charged, backbone phosphate groups of nucleic acids or protein carboxylate side chains, which can complicate their interpretation. This study examines the images of groups that include charged atoms that appear in recently-published, high resolution EM potential maps of the ribosome and beta-galactosidase. Comparisons of simulated maps of these same groups with their experimental counterparts highlight the impact that charge has on the appearance of electric potential maps.

AB - The food industry is often described as having more power and influence in nutrition policymaking than nutrition professionals, scientists and other practitioners working for the public interest; yet authors often allude to this point as an assumed truth, rather than an evidence-based fact. This paper applies social network analysis techniques to provide a concise evidence-based demonstration of the food industry's capacity to influence nutrition policymaking networks in Australia. Network analysis using four rounds of data collection was undertaken, and the capacity of individual actors and occupational categories to influence policy decision makers were analysed. Network graphs were developed using cluster analysis to identify the structure of clusters and the path distance of actors from decision makers. The assumed advantage for the 'food industry' was present both strategically in overall network position and with respect to the number of direct access points to 'decision makers', whereas 'nutrition professionals' were densely clustered together with limited links to key 'decision makers'. The results demonstrate that the food industry holds the strategic high ground in advocating their interests to policymakers in the contexts studied. Nutrition professionals may be hampered by their reliance on strong ties with other nutrition professionals as well as limited direct links to 'decision makers'. PMID- 27706892 TI - Oxygen delivery using neonatal self-inflating bags without reservoirs. AB - BACKGROUND: Guidelines recommend avoiding excessive oxygen during neonatal resuscitation. Recent studies have suggested that oxygen titration can be achieved using a self-inflating bag, but data on the effectiveness of resuscitators used in neonatal ventilation are scarce, The aim of this study was therefore to determine the amount of oxygen delivered using several brands of neonatal self-inflating resuscitation bags without reservoirs under different conditions with regard to oxygen flow rate, ventilation rate (VR), peak inspiratory pressure (PIP) range, and test lung compliance. METHODS: Oxygen concentration was measured under a variety of conditions. Combinations of oxygen flow rate (10, 5.0, 3.0 and 1.0 L/min), VR (40, 60 inflations/min), PIP range (20 25 cmH2 O, 35-40 cmH2 O), and test lung compliance (0.6, 1.0, 3.0, and 5.0 mL/cmH2 O) were examined using six kinds of self-inflating bag. RESULTS: Delivered oxygen concentration varied widely (30.1-96.7%) and had a significant positive correlation with gas flow rate in all of the bags. Delivered oxygen concentration was also negatively correlated with PIP in all of the bags and with VR in some of them. Test lung compliance did not affect delivered oxygen concentration. CONCLUSION: The use of neonatal resuscitation self-inflating bags without reservoirs resulted in different delivered oxygen concentrations depending on gas flow rate, VR, PIP, and manufacturer, but not on lung compliance. This suggests that targeted oxygen concentrations could be delivered, even in lungs with decreased compliance, during resuscitation. PMID- 27706893 TI - How Factor Analysis Results May Change Due to Country Context. AB - PURPOSE: To present how factor analysis results of a Practice Environment Scale of the Nursing Work Index (PES-NWI) translation changed due to country context. DESIGN: Validity and reliability analysis of a cross-culturally adapted, Polish translation of the PES-NWI came from a cross-sectional, national survey that included 2,605 registered nurses working in surgical (50.4%) and medical (49.6%) units of 30 Polish hospitals. METHODS: Exploratory factor analysis (EFA) using the principal component analysis (PCA) method with varimax rotation and confirmatory factor analysis (CFA) was used to examine factor structure of the instrument in the Polish context. Zero-order and partial Pearson correlation coefficients were used to establish the range of variance shared by the dimensions of the Polish version. The Cronbach's alpha coefficient determined internal consistency reliability. The internal consistency of the scale was also tested based on Kline's criterion. FINDINGS: The PCA conducted in the sample of Polish nurses extracted six factors, explaining together 56% of the total variance. The varimax rotation, however, restricted results to five factors, explaining 52.7% of the total variance and generating a factor structure closer to that based on previous studies. The CFA model, based on a PCA solution with five nonorthogonal factors, fitted data better than the theoretically driven model. CONCLUSIONS: Dimensions of the PES-NWI nurses' work environments remain conceptually consistent in Poland, but load differently. Health system or nursing profession factors related to the country context are potential explanations for these differences. CLINICAL RELEVANCE: When using a translation of the Practice Environment Scale of the Nursing Work Index-Revised to examine the influences of work environment quality on nursing and patient outcomes, it is important to consider contextual differences when using results to inform policy. PMID- 27706894 TI - cGAS-cGAMP-STING: The three musketeers of cytosolic DNA sensing and signaling. AB - Innate immunity is the first line of host defense against invading pathogens. The detection of aberrant nucleic acids which represent some conserved PAMPs triggers robust type I IFN-mediated innate immune responses. Host- or pathogen-derived cytosolic DNA binds and activates the DNA sensor cGAS, which synthesizes the second messenger 2'3'-cGAMP and triggers STING-dependent downstream signaling. Here, we highlight recent progress in cGAS-cGAMP-STING, the Three Musketeers of cytosolic DNA sensing and signaling, and their essential roles in infection, autoimmune diseases, and cancer. We also focus on the regulation of these critical signal components by variant host/pathogen proteins and update our understanding of this indispensable pathway to provide new insights for drug discovery.

AB - During orthotopic liver transplantation (OLT), clamping of the portal vein induces splanchnic venous congestion and accumulation of noxious compounds. These adverse effects could increase ischemia/reperfusion injury and subsequently the risk of graft dysfunction, especially for grafts harvested from extended criteria donors (ECDs). Temporary portocaval shunt (TPCS) could prevent these complications. Between 2002 and 2013, all OLTs performed in our center were retrospectively analyzed and a propensity score matching analysis was used to compare the effect of TPCS in 686 patients (343 in each group). Patients in the TPCS group required fewer intraoperative transfusions (median number of packed red blood cells-5 versus 6; P = 0.02; median number of fresh frozen plasma-5 versus 6; P = 0.02); had improvement of postoperative biological parameters (prothrombin time, Factor V, international normalized ratio, alkaline phosphatase, and gamma-glutamyltransferase levels); and showed significant reduction of biliary complications (4.7% versus 10.2%; P = 0.006). Survival analysis revealed that TPCS improved 3-month graft survival (94.2% versus 88.6%; P = 0.01) as well as longterm survival of elderly (ie, age > 70 years) donor grafts (P = 0.02). In conclusion, the use of TPCS should be recommended especially when considering an ECD graft. Liver Transplantation 23 174-183 2017 AASLD. PMID- 27706897 TI - Reply. PMID- 27706896 TI - The soluble mannose receptor is released from the liver in cirrhotic patients, but is not associated with bacterial translocation. AB - BACKGROUND & AIMS: Intestinal bacterial translocation is involved in activation of liver macrophages in cirrhotic patients. Macrophages play a key role in liver inflammation and are involved in the pathogenesis of cirrhosis and complications. Bacterial translocation may be determined by presence of bacterial DNA and macrophage activation, by the soluble mannose receptor. We hypothesize that the soluble mannose receptor is released from hepatic macrophages in cirrhosis and associated with bacterial DNA, portal pressure and complications. METHODS: We investigated 28 cirrhotic patients set for transjugular intrahepatic portosystemic shunt insertion as a result of refractory ascites (n=17), acute (n=3), or recurrent variceal bleeding (n=8). We analysed plasma from the portal and hepatic veins for bacterial DNA and soluble mannose receptor with qPCR and ELISA. RESULTS: The median soluble mannose receptor level was elevated in the hepatic vein compared with the portal vein (0.57(interquartile range 0.31) vs 0.55(0.40) mg/L, P=.005). The soluble mannose receptor levels were similar in bacterial DNA-positive and -negative patients. The soluble mannose receptor level in the portal and hepatic veins correlated with the portal pressure prior to transjugular intrahepatic portosystemic shunt insertion (r=.52, P<.008, both) and the levels correlated with Child-Pugh score (r=.63 and r=.56, P<.004, both). We observed higher soluble mannose receptor levels in patients with acute variceal bleeding compared to other indications (P<.05). CONCLUSION: This study showed hepatic soluble mannose receptor excretion with a higher level in the hepatic than the portal vein, though with no associations to bacterial DNA. We observed associations between soluble mannose receptor levels and portal pressure and higher levels in patients with acute variceal bleeding indicating the soluble mannose receptor as a marker of complications of cirrhosis, but not bacterial translocation. PMID- 27706898 TI - Do environmental pollutants increase obesity risk in humans? AB - OBJECTIVES: Obesity has become a global epidemic and threat to public health. A good understanding of the causes can help attenuate the risk and spread. Environmental pollutants may have contributed to the rising global obesity rates. Some research reported associations between chemical pollutants and obesity, but findings are mixed. This study systematically examined associations between chemical pollutants and obesity in human subjects. METHODS: Systematic review of relevant studies published between 1 January 1995 and 1 June 2016 by searching PubMed and MEDLINE(r). RESULTS: Thirty-five cross-sectional (n = 17) and cohort studies (n = 18) were identified that reported on associations between pollutants and obesity measures. Of them, 16 studies (45.71%) reported a positive association; none reported a sole inverse association; three (8.57%) reported a null association only; six (17.14%) reported both a positive and null association; seven (20.00%) reported a positive and inverse association; and three studies (8.57%) reported all associations (positive, inverse and null). Most studies examined the association between multiple different pollutants, different levels of concentration and in subsamples, which results in mixed results. Thirty-three studies reported at least one positive association between obesity and chemicals, such as polychlorinated biphenyls, biphenyl A, dichlorodiphenyltrichloroethane, dichlorodiphenyldichloroethylene and more. Certain chemicals, such as biphenyl A, were more likely to have high ORs ranging from 1.0 to 3.0, whereas highly chlorinated polychlorinated biphenyls were more likely to have negative ORs. Effects of chemicals on the endocrine system and obesity might vary by substance, exposure level, measure of adiposity and subject characteristics (e.g. sex and age). CONCLUSIONS: Accumulated evidences show positive associations between pollutants and obesity in humans. Future large, long-term, follow-up studies are needed to assess impact of chemical pollutants on obesity risk and related mechanisms.

AB - Gambogic acid (GA) exhibits a broad spectrum of anticancer activity and low chemotoxicity to normal tissues. However, poor aqueous solubility and sensitivity to hydrolysis make its pharmaceutical applications a challenge. Linear and branched Arg-based poly(ester urea urethane)s (Arg-PEUUs), folate (FA)-conjugated Arg PEUUs (FA-Arg-PEUUs), and their self-assembled nanoparticles (NPs) were designed, synthesized, and studied as the potential GA carriers for cancer treatment. The average diameters of linear or branched Arg-PEUU/FA-Arg-PEUU NPs were 98-267 nm. FA-Arg-PEUU NPs adhered onto and were internalized into HeLa and A549 cells, and showed no cytotoxicity. The GA loading efficiency in the NP carriers ranged from 40 to 98%, depending on the feed weight ratio of GA to Arg PEUU and the Arg-PEUU polymer structure (i.e., linear vs. branched). The GA at 2 ug/mL concentration delivered by the FA-Arg-PEUU NP carriers had higher cytotoxicity and induced a higher apoptosis percentage against folate receptor (FR)-overexpressed HeLa or HCT116 than Arg-PEUU NPs. When compared to the free GA treatment, the GA loaded in the FA-Arg-PEUU NP carriers also led to significant loss of the mitochondrial membrane potential in a higher percentage of the cancer cell population and more DNA fragmentation. The GA loaded in FA-Arg-PEUU NP carriers at as low as 0.6 ug/mL GA concentration led to lower MMP-2 and MMP-9 activity of cancer cells compared to free GA, suggesting that GA-loaded Arg-PEUU NPs may have greater potential to reduce cancer cell invasion and metastasis than free GA.

PMID- 27706901 TI - Targeting a Targeted Drug: An Approach Toward Hypoxia-Activatable Tyrosine Kinase Inhibitor Prodrugs. AB - Tyrosine kinase inhibitors (TKIs), which have revolutionized cancer therapy over the past 15 years, are limited in their clinical application due to serious side effects. Therefore, we converted two approved TKIs (sunitinib and erlotinib) into 2-nitroimidazole-based hypoxia-activatable prodrugs. Kinetics studies showed very different stabilities over 24 h; however, fast reductive activation via E. coli nitroreductase could be confirmed for both panels. The anticancer activity and signaling inhibition of the compounds against various human cancer cell lines were evaluated in cell culture. These data, together with molecular docking simulations, revealed distinct differences in the impact of structural modifications on drug binding to the enzymes: whereas the catalytic pocket of the epidermal growth factor receptor (EGFR) accepted all new erlotinib derivatives, the vascular endothelial growth factor receptor (VEGFR)-inhibitory potential in the case of the sunitinib prodrugs was dramatically diminished by derivatization. In line, hypoxia dependency of ERK signaling inhibition was observed with the sunitinib prodrugs, while oxygen levels had no impact on the activity of the erlotinib derivatives. Overall, proof of principle could be shown for this concept, and the results obtained are an important basis for the future development of tyrosine kinase inhibitor prodrugs.

AB - Cell nanoencapsulation, generating cell-in-shell structures ("artificial spores"), provides a chemical toolbox for controlling the cellular behaviors and functional characteristics of individual cells. Among the shell materials studied so far, naturally occurring polyphenolic compounds, including polydopamine and tannic acid, have intensively been employed in cell-surface engineering, because their material-independent coating property eliminates an extra priming step for inducing subsequent shell formation. Albeit successful in generating cell-in shell structures, the coating of polyphenolic compounds generally requires alkaline conditions and/or high salt conditions, which are not compatible with certain cell types. In this work, we demonstrate that the nanocoating of individual cells with a plant-derived phenolic compound, pyrogallol (1,2,3 trihydroxybenzene), occurs at mildly alkaline pH of 7.8 in an isotonic buffer. Three different cell types (anucleate, microbial, and mammalian cells) are coated with pyrogallol without noticeable decrease in cell viability. The protocol developed in this work could be applied to other polyphenolic compounds, and, considering the many polyphenols identified as a coating material, provides an advanced chemical tool in cell-surface engineering.

AB - The aerobic oxidative annulation of chalcones, pyridines/isoquinoline and ethyl chloroacetate to indolizines was achieved by cascade reaction. Various functional groups on chalcones were tolerated. And different pyridines derivatives could also be suitable substrates. Ethyl chloroacetate is an essential component in participating of the oxidative annulation process. Overall, this protocol is very practical and efficient by using molecular oxygen as oxidant with high selectivity for the annulation product.

PMID- 27706903 TI - Combination of tauroursodeoxycholic acid and N-acetylcysteine exceeds standard treatment for acetaminophen intoxication. AB - BACKGROUND & AIMS: Acetaminophen overdose in mice is characterized by hepatocyte endoplasmic reticulum stress, which activates the unfolded protein response, and centrilobular hepatocyte death. We aimed at investigating the therapeutic potential of tauroursodeoxycholic acid, a hydrophilic bile acid known to have anti-apoptotic and endoplasmic reticulum stress-reducing capacities, in experimental acute liver injury induced by acetaminophen overdose. METHODS: Mice were injected with 300 mg/kg acetaminophen, 2 hours prior to receiving tauroursodeoxycholic acid, N-acetylcysteine or a combination therapy, and were euthanized 24 hours later. Liver damage was assessed by serum transaminases, liver histology, terminal deoxynucleotidyl transferase dUTP nick end labelling staining, expression profiling of inflammatory, oxidative stress, unfolded protein response, apoptotic and pyroptotic markers. RESULTS: Acetaminophen overdose resulted in a significant increase in serum transaminases, hepatocyte cell death, unfolded protein response activation, oxidative stress, NLRP3 inflammasome activation, caspase 1 and pro-inflammatory cytokine expressions. Standard of care, N-acetylcysteine and, to a lesser extent, tauroursodeoxycholic treatment were associated with significantly lower transaminase levels, hepatocyte death, unfolded protein response activation, oxidative stress markers, caspase 1 expression and NLRP3 levels. Importantly, the combination of N acetylcysteine and tauroursodeoxycholic acid improved serum transaminase levels, reduced histopathological liver damage, UPR-activated CHOP, oxidative stress, caspase 1 expression, NLRP3 levels, IL-1beta levels and the expression of pro inflammatory cytokines and this to a greater extend than N-acetylcysteine alone. CONCLUSIONS: These findings indicate that a combination strategy of N acetylcysteine and tauroursodeoxycholic acid surpasses the standard of care in acetaminophen-induced liver injury in mice and might represent an attractive therapeutic opportunity for acetaminophen-intoxicated patients. PMID- 27706906 TI - Valproic acid selectively increases vascular endothelial tissue-type plasminogen activator production and reduces thrombus formation in the mouse. AB - : Essentials Stimulating endogenous fibrinolysis could be a novel antithrombotic strategy. The effect of valproic acid on endothelial tissue plasminogen activator in mice was investigated. Valproic acid increased tissue plasminogen activator expression in vascular endothelium. Valproic acid reduced fibrin deposition and thrombus formation after vascular injury. SUMMARY: Background The endogenous fibrinolytic system has rarely been considered as a target to prevent thrombotic disease. Tissue-type plasminogen activator (t-PA) production is potently increased by histone deacetylase (HDAC) inhibitors in endothelial cells in vitro, but whether this translates into increased vascular t-PA production and an enhanced fibrinolytic capacity in vivo is unknown. Objectives To determine whether the HDAC inhibitor valproic acid (VPA) stimulates production of t-PA in the vasculature of mice, and whether VPA pretreatment affects fibrin deposition and clot formation after mechanical vessel injury. Methods Mice were injected with VPA twice daily for up to 5 days. t-PA mRNA, and antigen expression in the mouse aorta and the circulating levels of t-PA were determined. Fibrin and thrombus dynamics after mechanical vessel injury were monitored with intravital confocal microscopy. Potential effects of VPA on platelets and coagulation were investigated. Results and Conclusions We found that VPA treatment increased vascular t-PA production in vivo and, importantly, that VPA administration was associated with reduced fibrin accumulation and smaller thrombi in response to vascular injury, but still was not associated with an increased risk of bleeding. Furthermore, we observed that higher concentrations of VPA were required to stimulate t-PA production in the brain than in the vasculature. Thus, this study shows that VPA can be dosed to selectively manipulate the fibrinolytic system in the vascular compartment and reduce thrombus formation in vivo. PMID- 27706907 TI - Staphylococcus aureus and Escherichia coli dual-species biofilms on nanohydroxyapatite loaded with CHX or ZnO nanoparticles. AB - Implant-associated infections are caused by surface-adhering microorganisms persisting as biofilms, resistant to host defense and antimicrobial agents. Given the limited efficacy of traditional antibiotics, novel strategies may rely on the prevention of such infections through the design of new biomaterials. In this work, two antimicrobial agents applied to nanohydroxyapatite materials-namely, chlorhexidine digluconate (CHX) and zinc oxide (ZnO) nanoparticles-were compared concerning their ability to avoid single- or dual-species biofilms of Staphylococcus aureus and Escherichia coli. The resulting biofilms were quantified by the enumeration of colony-forming units and examined by confocal microscopy using both Live/Dead staining and bacterial-specific fluorescent in situ hybridization. The sessile population arrangement was also observed by scanning electron microscopy. Both biomaterials showed to be effective in impairing bacterial adhesion and proliferation for either single- or dual-species biofilms. Furthermore, a competitive interaction was observed for dual-species biofilms wherein E. coli exhibited higher proliferative capacity than S. aureus, an inverse behavior from the one observed in single-species biofilms. Therefore, either nanoHA-CHX or nanoHA-ZnO surfaces appear as promising alternatives to antibiotics for the prevention of devices-related infections avoiding the critical risk of antibiotic-resistant strains emergence.

PMID- 27706909 TI - Repair of caudal septal deviation: the fishing line technique. AB - BACKGROUND: Repair of caudal septal deviation using currently described methods is challenging technically. The aim of this work is to describe a novel and simple technique for the treatment of caudal septal deviations that protects the nasal tip, by fixating of cartilage to the columella. METHODS: All patients with caudal septal deviation operated on between June 2008 to November 2013 in 2 major medical centers were operated using the "fishing line technique." Patient satisfaction was recorded by a standard questionnaire (16-item Sino-Nasal Outcome Test [SNOT-16]), before and after surgery. The fishing line technique was performed in 63 patients with a severe caudal septal deviation of which 14 also had rhinoplasty. A mucoperichondrial flap was elevated on either side of the damaged septal cartilage. The cartilage was excised and remodeled into a straight sheet, and then repositioned between the mucoperichondrial flaps, and fixed to the septal columella. RESULTS: Mean age of the study group was 36 years. Follow up ranged from 24 to 70 months. At the last follow-up, the septum was straight in all cases, with no deviation from the nostrils to the choana. Good airway was found in 53 patients. Eight patients had partial turbinate hypertrophy with an impaired airway, and 2 had severe turbinate hypertrophy. SNOT-16 mean score improved from 27 to 10 (p < 0.001). All patients were satisfied with the aesthetic outcome. CONCLUSION: The fishing-line technique for severe caudal septum deviations is easy to perform and yields satisfactory anatomic and aesthetic results.

The daughters had 15 and 18 supernumerary teeth, respectively. The mother had normal dentition. Mutation analysis of TRPS1 showed a novel heterozygous c.3809_3811delACTinsCATGTTGTG mutation in all. This mutation is predicted to cause amino acid changes in the Ikaros-like zinc finger domain near the C-terminal end of TRPS1, which is important for repressive protein function. The results of our study and the comprehensive review of the literature show that pathways of forming supernumerary teeth appear to involve APC and RUNX2, the genes responsible for familial adenomatous polyposis syndrome and cleidocranial dysplasia, respectively. The final pathway resulting in supernumerary teeth seems to involve Wnt, a morphogen active during many stages of development. (c) 2016 Wiley Periodicals, Inc.

AB - With its ease of availability during adolescence, sweetened ethanol ('alcopops') is consumed within many contexts. We asked here whether genetically based differences in social motivation are associated with how the adolescent social environment impacts voluntary ethanol intake. Mice with previously described differences in sociability (BALB/cJ, C57BL/6J, FVB/NJ and MSM/MsJ strains) were weaned into isolation or same-sex pairs (postnatal day, PD, 21), and then given continuous access to two fluids on PDs 34-45: one containing water and the other containing an ascending series of saccharin-sweetened ethanol (3-6-10%). Prior to the introduction of ethanol (PDs 30-33), increased water and food intake was detected in some of the isolation-reared groups, and controls indicated that isolated mice also consumed more 'saccharin-only' solution. Voluntary drinking of 'ethanol-only' was also higher in a subset of the isolated groups on PDs 46-49. However, sweetened ethanol intake was increased in all isolated strain * sex combinations irrespective of genotype. Surprisingly, blood ethanol concentration (BEC) was not different between these isolate and socially housed groups 4 h into the dark phase. Using lickometer-based measures of intake in FVB mice, we identified that a predominance of increased drinking during isolation transpired outside of the typical circadian consumption peak, occurring ~8.5 h into the dark phase, with an associated difference in BEC. These findings collectively indicate that isolate housing leads to increased consumption of rewarding substances in adolescent mice independent of their genotype, and that for ethanol this may be because of when individuals drink during the circadian cycle. PMID- 27706913 TI - Longitudinal retention of anatomical knowledge in second-year medical students. AB - The Radboud University Medical Center has a problem-based, learner-oriented, horizontally, and vertically integrated medical curriculum. Anatomists and clinicians have noticed students' decreasing anatomical knowledge and the disability to apply knowledge in diagnostic reasoning and problem solving. In a longitudinal cohort, the retention of anatomical knowledge gained during the first year of medical school among second-year medical students was assessed. In May 2011, 346 medical students applied for the second-year gastro-intestinal (GI) tract course. The students were asked to participate in a reexamination of a selection of anatomical questions of an examination from October 2009. The examination consisted of a clinical anatomy case scenario and two computed tomography (CT) images of thorax and abdomen in an extended matching format. A total of 165 students were included for analysis. In 2011, students scored significantly lower for the anatomy examination compared to 2009 with a decline in overall examination score of 14.7% (+/-11.7%). Decrease in knowledge was higher in the radiological questions, compared to the clinical anatomy cases 17.5% (+/-13.6%) vs. 7.9% (+/-10.0%), respectively, d = 5.17. In both years, male students scored slightly better compared to female students, and decline of knowledge seems somewhat lower in male students (13.1% (+/-11.1%) vs. 15.5% (+/ 12.0%), respectively), d = -0.21. Anatomical knowledge in the problem-oriented horizontal and vertical integrated medical curriculum, declined by approximately 15% 1.5 year after the initial anatomy course. The loss of knowledge in the present study is relative small compared to previous studies. Anat Sci Educ 10: 242-248. (c) 2016 American Association of Anatomists.

AB - AIM: To review the effects of mindfulness-based interventions on Registered Nurses and nursing students. BACKGROUND: Work-related stress among nurses is estimated to be the biggest occupational health problem after musculoskeletal disorders. DESIGN: A mixed-method systematic review incorporating quantitative and qualitative data was conducted. DATA SOURCES: Studies on the effects of mindfulness-based interventions for nurses and nursing students published between 1980 and 2014 were identified through a systematic search in electronic databases: Medline, Embase, PsycINFO, Cochrane Library and Cinahl. REVIEW METHODS: Data analysis was conducted based on the framework of Thomas and Harden (2004). RESULTS: A total of 32 studies, including 17 controlled designs, 11 pre post designs and four qualitative designs were reviewed. Meta-analysis suggests that mindfulness-based interventions may be effective in significantly reducing state anxiety and depression at posttreatment and state anxiety and trait anxiety at follow-up. Qualitative studies and uncontrolled studies shed light on benefits overlooked in RCTs, including improvements in the well-being of individuals (e.g. inner state of calmness, awareness and enthusiasm) and improved performance at work (better communication with colleagues and patients, higher sensitivity to patients' experiences, clearer analysis of complex situations and emotional regulation in stressful contexts). CONCLUSIONS: Mindfulness appeared to improve nurses' mental health significantly. It could be used in worksite health promotion programmes. Only a few studies have explored the impact of mindfulness on nurses' professional behaviours and their relationships with patients and colleagues. Future research should further explore the long-term impacts of mindfulness on performance and well-being at work using sound methodological designs. PMID- 27706914 TI - Ferroelectric BiFeO3 as an Oxide Dye in Highly Tunable Mesoporous All-Oxide Photovoltaic Heterojunctions. AB - As potential photovoltaic materials, transition-metal oxides such as BiFeO3 (BFO) are capable of absorbing a substantial portion of solar light and incorporating ferroic orders into solar cells with enhanced performance. But the photovoltaic application of BFO has been hindered by low energy-conversion efficiency due to poor carrier transport and collection. In this work, a new approach of utilizing BFO as a light-absorbing sensitizer is developed to interface with charge transporting TiO2 nanoparticles. This mesoporous all-oxide architecture, similar to that of dye-sensitized solar cells, can effectively facilitate the extraction of photocarriers. Under the standard AM1.5 (100 mW cm-2 ) irradiation, the optimized cell shows an open-circuit voltage of 0.67 V, which can be enhanced to 1.0 V by tailoring the bias history. A fill factor of 55% is achieved, which is much higher than those in previous reports on BFO-based photovoltaic devices. The results provide here a new viable approach toward developing highly tunable and stable photovoltaic devices based on ferroelectric transition-metal oxides. PMID- 27706915 TI - Genome-wide transcriptome analysis of Aspergillus fumigatus exposed to osmotic stress reveals regulators of osmotic and cell wall stresses that are SakAHOG1 and MpkC dependent. AB - Invasive aspergillosis is predominantly caused by Aspergillus fumigatus, and adaptations to stresses experienced within the human host are a prerequisite for the survival and virulence strategies of the pathogen. The central signal transduction pathway operating during hyperosmotic stress is the high osmolarity glycerol mitogen-activated protein kinase cascade. A. fumigatus MpkC and SakA, orthologues of the Saccharomyces cerevisiae Hog1p, constitute the primary regulator of the hyperosmotic stress response. We compared A. fumigatus wild-type transcriptional response to osmotic stress with the DeltampkC, DeltasakA, and DeltampkC DeltasakA strains. Our results strongly indicate that MpkC and SakA have independent and collaborative functions during the transcriptional response to transient osmotic stress. We have identified and characterized null mutants for four A. fumigatus basic leucine zipper proteins transcription factors. The atfA and atfB have comparable expression levels with the wild-type in DeltampkC but are repressed in DeltasakA and DeltampkC DeltasakA post-osmotic stress. The atfC and atfD have reduced expression levels in all mutants post-osmotic stress. The atfA-D null mutants displayed several phenotypes related to osmotic, oxidative, and cell wall stresses. The DeltaatfA and DeltaatfB were shown to be avirulent and to have attenuated virulence, respectively, in both Galleria mellonella and a neutropenic murine model of invasive pulmonary aspergillosis. PMID- 27706917 TI - Enhancing the osteoblastic differentiation through nanoscale surface modifications. AB - Human mesenchymal stem cells (MSCs) showed larger differentiation into osteoblasts on nanoscale amorphous titanium oxide (TiO2 ) coatings in comparison to polycrystalline TiO2 coatings or native oxide layers. In this article, we showed that the subtle alterations in the surface properties due to a different atomic ordering of titanium oxide layers could substantially modify the osteoblastic differentiation of MSCs. Amorphous (a) and polycrystalline (c) TiO2 coatings were deposited on smooth (PT) and microstructured sandblasted/acid etched (SLA) Ti substrates using a magnetron sputtering system. The surface roughness, water contact angle, structure, and composition were measured using confocal microscopy, drop sessile drop, X-ray diffraction, and X-ray photoelectron spectroscopy, respectively. The ~70-nm-thick coatings presented a well-passivated and uniform TiO2 (Ti4+ ) surface composition, while the substrates (native oxide layer) showed the presence of Ti atoms in lower valence states. The polycrystalline TiO2 -coated surfaces (cPT and cSLA) showed the same cell attachment as the uncoated metallic surfaces (PT and SLA), and in both cases, it was lower on the rough than on the smooth surfaces. However, attachment and differentiation were significantly increased on the amorphous TiO2 -coated surfaces (aPT and aSLA). The amorphous coated Ti surfaces presented the highest expression of integrins and production of osteogenic proteins in comparison to the uncoated and crystalline-coated Ti surfaces.

AB - The common marmoset (Callithrix jacchus) is a small New World monkey that has gained significant recent interest in neuroscience research, not only because of its compatibility with gene editing techniques, but also due to its tremendous versatility as an experimental animal model. Neuroimaging modalities, including anatomical (MRI) and functional magnetic resonance imaging (fMRI), complemented by two-photon laser scanning microscopy and electrophysiology, have been at the forefront of unraveling the anatomical and functional organization of the marmoset brain. High-resolution anatomical MRI of the marmoset brain can be obtained with remarkable cytoarchitectonic detail. Functional MRI of the marmoset brain has been used to study various sensory systems, including somatosensory, auditory, and visual pathways, while resting-state fMRI studies have unraveled functional brain networks that bear great correspondence to those previously described in humans. Two-photon laser scanning microscopy of the marmoset brain has enabled the simultaneous recording of neuronal activity from thousands of neurons with single cell spatial resolution. In this article, we aim to review the main results obtained by our group and by our colleagues in applying neuroimaging techniques to study the marmoset brain. (c) 2016 Wiley Periodicals, Inc.

AB - Callithrix jacchus are small-bodied Neotropical primates popularly known as common marmosets. They are endemic to Northeast Brazil and occur in contrasting environments such as the humid Atlantic Forest and the dry scrub forest of the Caatinga. Common marmosets live in social groups, usually containing only one breeding pair. These primates have a parental care system in which individuals help by providing assistance to the infants even when they are not related to them. Free-ranging groups use relatively small home ranges (0.5-5 hectares) and have an omnivorous diet. Because of the shape of their teeth, they actively gouge tree bark to extract and consume exudates. When foraging for live prey, they adjust their strategy according to the type of prey. The successful use of appropriate hunting strategies depends not only on age but also on prey type and seems to be mediated by learning and experience. Indeed, common marmosets have shown unexpected cognitive abilities, such as true imitation. All these aspects seem to have contributed to the ecological success of this species. Callithrix jacchus has been widely studied, especially in captivity; even so, a number of questions remain to be answered about its biology, ecology, and behavior, both in captivity and the wild. A richer understanding of marmosets' natural behavior and ecology can have a significant impact on shaping ongoing and future neuroscience research. (c) 2016 Wiley Periodicals, Inc.

AB - It is important to study the neural connectivities and functions in primates. For this purpose, it is critical to be able to transfer genes to certain neurons in the primate brain so that we can image the neuronal signals and analyze the function of the transferred gene. Toward this end, our team has been developing gene transfer systems using viral vectors. In this review, we summarize our current achievements as follows. 1) We compared the features of gene transfer using five different AAV serotypes in combination with three different promoters, namely, CMV, mouse CaMKII (CaMKII), and human synapsin 1 (hSyn1), in the marmoset cortex with those in the mouse and macaque cortices. 2) We used target-specific double-infection techniques in combination with TET-ON and TET-OFF using lentiviral retrograde vectors for enhanced visualization of neural connections. 3) We used an AAV-mediated gene transfer method to study the transcriptional control for amplifying fluorescent signals using the TET/TRE system in the primate neocortex. We also established systems for shRNA mediated gene targeting in a neocortical region where a gene is significantly expressed and for expressing the gene using the CMV promoter for an unexpressed neocortical area in the primate cortex using AAV vectors to understand the regulation of downstream genes. Our findings have demonstrated the feasibility of using viral vector mediated gene transfer systems for the study of primate cortical circuits using the marmoset as an animal model.

PMID- 27706920 TI - Oncostatin m impairs brown adipose tissue thermogenic function and the browning of subcutaneous white adipose tissue. AB - OBJECTIVE: Since oncostatin m (OSM) is elevated in adipose tissue in conditions of obesity and type 2 diabetes in mice and humans, the aim of this study was to determine whether this cytokine plays a crucial role in the impairment of brown adipose tissue (BAT) activity and browning capacity that has been observed in people with obesity. METHODS: C57BL/6J mice rendered obese by high-fat diet, their lean controls, and C57BL/6J mice fed a standard diet and implanted subcutaneously with a mini pump through a surgical procedure to deliver OSM or placebo were used. Preadipocytes or fully differentiated brown adipocytes were treated with OSM or vehicle with or without norepinephrine before harvesting. RNA was extracted and processed for qPCR analysis. Media from mature adipocytes was also collected to measure glycerol levels. RESULTS: Studies demonstrated that OSM gene expression was increased in BAT of mice fed a high-fat diet. In addition, exogenous OSM impaired BAT activity and the browning capacity of white adipose tissue in vitro and in vivo. CONCLUSIONS: Overall, the results reveal a negative role for OSM on BAT and on the browning of white adipose tissue. Therefore, further studies are necessary to demonstrate whether OSM inhibition is a potential treatment for metabolic disorders. PMID- 27706921 TI - Mass spectrometric characterisation of darbepoetin alfa biosimilars with C terminal arginine residues. AB - Human erythropoietin (EPO) and recombinant human EPO (rEPO) are approximately 30 kDa glycosylated proteins comprising 165 amino acids. Darbepoetin alfa (NESP) is a glycosylated protein encompassing five changes in the amino acid sequence of human EPO, which contains two extra sugar chains. NESP is under patent protection in the USA until May 2024 and in Europe until July 2016, which suggests that the number of NESP biosimilars might substantially increase. The detailed characterisation of biosimilar products are required to ensure the identity and purity of the biosimilar products in terms of safety and efficacy for patients. In this study, a mass spectrometric characterisation of NESP biosimilar products is demonstrated. The study comprises a time-of-flight mass spectrometry characterisation for the asialo-NESPs after sialidase digestion and primary structure characterisation using bottom-up analysis after endoproteinase Glu-C digestion of the core protein. The study revealed that there was a wide range of glycoforms spaced by 365 Da intervals, namely, HexHexNAc units, which indicated that NESP biosimilars likely contained more N-acetyllactosamine units in their molecules. The bottom-up analysis also showed that the NESP biosimilars, as well as a rEPO biosimilar, contain not only the des-arginine product but also the C terminal arginine product comprising 166 amino acids, whereas the innovator products contain des-arginine EPO comprising only 165 amino acids. The C-terminal arginine EPO would be used as a potential marker for doping with EPO bisimilaras. These findings also point to a need for the investigation of immunogenicity and comparability for the biosimilar products. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - The oral pathogen Aggregatibacter actinomycetemcomitans uses pga gene locus for the production of an exopolysaccharide made up of a linear homopolymer of beta 1,6-N-acetyl-d-glucosamine (PGA). An enzyme encoded by the pgaB of the pga operon in A. actinomycetemcomitans is a de-N-acetylase, which is used to alter the PGA. The full length enzyme (AaPgaB) and the N-terminal catalytic domain (residues 25 290, AaPgaBN) from A. actinomycetemcomitans were cloned, expressed and purified. The enzymatic activities of the AaPgaB enzymes were determined using 7 acetoxycoumarin-3-carboxylic acid as the substrate. The AaPgaB enzymes displayed significantly lower de-N-acetylase activity compared with the activity of the deacetylase PdaA from Bacillus subtilis, a member of the CE4 family of enzymes. To delineate the differences in the activity and the active site architecture, the structure of AaPgaBN was determined. The AaPgaBN structure has two metal ions in the active site instead of one found in other CE4 enzymes. Based on the crystal structure comparisons among the various CE4 enzymes, two residues, Q51 and R271, were identified in AaPgaB, which could potentially affect the enzyme activity. Of the two mutants generated, Q51E and R271K, the variant Q51E showed enhanced activity compared with AaPgaB, validating the requirement that an activating aspartate residue in the active site is essential for higher activity. In summary, our study provides the first structural evidence for a di-nuclear metal site at the active site of a member of the CE4 family of enzymes, evidence that AaPgaBN is catalytically active and that mutant Q51E exhibits higher de-N acetylase activity.

AB - OBJECTIVE: To determine the influence of glycolytic inhibition on the adipocyte inflammatory response. METHODS: To determine the effect of 2-deoxyglucose (2-DOG) on the inflammatory response, mature 3T3-L1 adipocytes were co-treated with 2-DOG and LPS or TNF. To determine the effect of endoplasmic reticulum stress on TNF induced induction of chemokines, adipocytes were pretreated with thapsigargin or salubrinal. Chemokine mRNA levels were determined using quantitative real-time PCR, and secretion of CCL2 was determined by Western blot. RESULTS: 2-DOG treatment reduced the ability of LPS and TNF to induce CCL2 mRNA levels and reduced secreted CCL2 protein levels in a dose-dependent manner. A similar pattern of mRNA regulation was observed for other chemokines. The attenuation of TNF-induced CCL2 mRNA levels occurred regardless of whether glucose or pyruvate was present in the media, suggesting that mechanisms other than glycolysis might mediate the observed effects. Treatment with the endoplasmic reticulum stressor thapsigargin and the endoplasmic reticulum signaling activator salubrinal reduced chemokine mRNA levels similarly to 2-DOG. CONCLUSIONS: Collectively, our data indicate that 2-DOG suppresses inflammatory chemokine induction in adipocytes. The effects of 2-DOG do not seem to be linked to glycolysis but correlate with endoplasmic reticulum stress activation. PMID- 27706924 TI - The corticospinal tract: Evolution, development, and human disorders. AB - The corticospinal tract (CST) plays a major role in cortical control of spinal cord activity. In particular, it is the principal motor pathway for voluntary movements. Here, we discuss: (i) the anatomic evolution and development of the CST across mammalian species, focusing on its role in motor functions; (ii) the molecular mechanisms regulating corticospinal tract formation and guidance during mouse development; and (iii) human disorders associated with abnormal CST development. A comparison of CST anatomy and development across mammalian species first highlights important similarities. In particular, most CST axons cross the anatomical midline at the junction between the brainstem and spinal cord, forming the pyramidal decussation. Reorganization of the pattern of CST projections to the spinal cord during evolution led to improved motor skills. Studies of the molecular mechanisms involved in CST formation and guidance in mice have identified several factors that act synergistically to ensure proper formation of the CST at each step of development. Human CST developmental disorders can result in a reduction of the CST, or in guidance defects associated with abnormal CST anatomy. These latter disorders result in altered midline crossing at the pyramidal decussation or in the spinal cord, but spare the rest of the CST. Careful appraisal of clinical manifestations associated with CST malformations highlights the critical role of the CST in the lateralization of motor control. (c) 2016 Wiley Periodicals, Inc.

AB - Learning in anatomy can be both spatially and visually complex. Pedagogical investigations have begun exploration as to how spatial ability may mitigate learning. Emerging hypotheses suggests individuals with higher spatial reasoning may attend to images differently than those who are lacking. To elucidate attentional patterns associated with different spatial ability, eye movements were measured in individuals completing a timed electronic mental rotation test (EMRT). The EMRT was based on the line drawings of Shepherd and Metzler. Individuals deduced whether image pairs were rotations (same) or mirror images (different). It was hypothesized that individuals with high spatial ability (HSA) would demonstrate shorter average fixation durations during problem solving and attend to different features of the EMRT than low spatial ability (LSA) counterparts. Moreover, question response accuracy would be associated with fewer fixations and shorter average response times, regardless of spatial reasoning ability. Average fixation duration in the HSA group was shorter than LSA (F(1,8) = 7.99; P = 0.022). Importantly, HSA and LSA individuals looked to different regions of the EMRT images (Fisher Exact Test: 12.47; P = 0.018); attending to the same locations only 34% of the time. Correctly answered questions were characterized by fewer fixations per question (F(1, 8) = 18.12; P = 0.003) and shorter average response times (F(1, 8) = 23.89; P = 0.001). The results indicate that spatial ability may influence visual attention to salient areas of images and this may be key to problem solving processes for low spatial individuals.

AB - The UGT2B17 gene deletion polymorphism is known to correlate to urinary concentration of testosterone-glucuronide and hence this genotype exerts a large impact on the testosterone/epitestosterone (T/E) ratio, a biomarker for testosterone doping. The objective of this study was to assess if DNA isolated from athletes' urine samples (n = 713) obtained in routine doping controls could be targeted for genotyping analysis for future integration in the athlete's passport. A control population (n = 21) including both urine and blood DNA was used for genotyping concordance test. Another aim was to study a large group (n = 596) of authentic elite athletes in respect of urinary steroid profile in relation to genetic variation. First we found that the genotype results when using urine-derived DNA did not correlate sufficiently with the genotype obtained from whole blood DNA. Secondly we found males with one or two UGT2B17 alleles had higher T/E (mean 1.63 +/- 0.93) than females (mean 1.28 +/- 1.08), p?0.001. Unexpectedly, we found that several male del/del athletes in power sports had a T/E ?1. If men in power sport exert a different urinary steroid profile needs to be further investigated. The other polymorphisms investigated in the CYP17A1, UGT2B7 and UGT2B15 genes did not show any associations with testosterone and epitestosterone concentrations. Our results show that genotyping using urine samples according to our method is not useful in an anti-doping setting. Instead, it is of importance for the anti-doping test programs to include baseline values in the ABP to minimize any putative impact of genotype. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - The design, synthesis, and in vitro biological studies of a biotin-carbazole dicyanovinyl-chlorambucil conjugate (Bio-CBZ-DCV-CBL; 6) are reported. This conjugate (6) is a multifunctional single-molecule appliance composed of a thiol sensor DCV functionality, a CBZ-derived phototrigger as well as fluorescent reporter, and CBL as the anticancer drug, and Bio as the cancer-targeting ligand. In conjugate 6, the DCV bond undergoes a thiol-ene click reaction at pH<7 with intracellular thiols, thereby shutting down internal charge transfer between the donor CBZ and acceptor DCV units, resulting in a change of the fluorescence color from green to blue, and thereby, sensing the tumor microenvironment. Subsequent photoirradiation results in release of the anticancer drug CBL in a controlled manner. PMID- 27706925 TI - Minocycline causes widespread cell death and increases microglial labeling in the neonatal mouse brain. AB - Minocycline, an antibiotic of the tetracycline family, inhibits microglia in many paradigms and is among the most commonly used tools for examining the role of microglia in physiological processes. Microglia may play an active role in triggering developmental neuronal cell death, although findings have been contradictory. To determine whether microglia influence developmental cell death, we treated perinatal mice with minocycline (45 mg/kg) and quantified effects on dying cells and microglial labeling using immunohistochemistry for activated caspase-3 (AC3) and ionized calcium-binding adapter molecule 1 (Iba1), respectively. Contrary to our expectations, minocycline treatment from embryonic day 18 to postnatal day (P)1 caused a > tenfold increase in cell death 8 h after the last injection in all brain regions examined, including the primary sensory cortex, septum, hippocampus and hypothalamus. Iba1 labeling was also increased in most regions. Similar effects, although of smaller magnitude, were seen when treatment was delayed to P3-P5. Minocycline treatment from P3 to P5 also decreased overall cell number in the septum at weaning, suggesting lasting effects of the neonatal exposure. When administered at lower doses (4.5 or 22.5 mg/kg), or at the same dose 1 week later (P10-P12), minocycline no longer increased microglial markers or cell death. Taken together, the most commonly used microglial "inhibitor" increases cell death and Iba1 labeling in the neonatal mouse brain. Minocycline is used clinically in infant and pediatric populations; caution is warrented when using minocycline in developing animals, or extrapolating the effects of this drug across ages.

PMID- 27706929 TI - Diagnostic accuracy and cost-effectiveness of different strategies to triage women with adnexal masses: a prospective study. AB - OBJECTIVE: Transvaginal sonography (TVS) and serum biomarkers are used widely in clinical practice to triage women with adnexal masses, but the effectiveness of current biomarkers is weak. The aim of this study was to determine the best method of diagnosing patients with adnexal masses, in terms of diagnostic accuracy and economic costs, among four triage strategies: (1) the International Ovarian Tumor Analysis group's simple rules (SR) for interpretation of TVS with subjective assessment (SA) by an experienced ultrasound operator when TVS results are inconclusive (referred to hereafter as SR +/- SA), (2) SR +/- SA and cancer antigen 125 (CA 125), (3) SR +/- SA and human epididymis protein 4 (HE4) and (4) SR +/- SA and the risk of malignancy algorithm (ROMA). Our main hypothesis was that the addition of the biomarkers to SR +/- SA could improve triaging of these patients in terms of diagnostic accuracy (i.e. malignant vs benign). As secondary analyses, we estimated the cost effectiveness of the four strategies and the diagnostic accuracy of SR +/- SA at the study hospitals. METHODS: Between February 2013 and January 2015, 447 consecutive patients who were scheduled for surgery for an adnexal mass at the S. Anna and Mauriziano Hospitals in Turin were enrolled in this multicenter prospective cohort study. Preoperative TVS was performed and preoperative CA 125 and HE4 levels were measured. Pathology reports were used to assess the diagnostic accuracy of the four triage strategies and the cost of each strategy was calculated. RESULTS: A total of 391 patients were included in the analysis: 57% (n = 221) were premenopausal and 43% (n = 170) were postmenopausal. The overall prevalence of malignancy was 21%. SR were conclusive in 89% of patients and thus did not require SA; the overall performance of SR +/- SA showed a sensitivity of 82%, specificity of 92% and positive and negative predictive values and positive and negative likelihood ratios of 74%, 95%, 10.5 and 0.19, respectively. In premenopausal women, mean cost among the four triage strategies varied from ?36.41 for SR +/- SA to ?70.12 for SR +/- SA + ROMA. The addition of biomarkers to SR +/- SA showed no diagnostic advantage compared with SR +/- SA alone and was more costly. Among postmenopausal women, mean cost among the four triage strategies varied from ?39.52 for SR +/- SA to ?73.23 for SR +/- SA + ROMA. Among these women, SR +/- SA + CA 125 and SR +/- SA + ROMA had a higher sensitivity (both 92% (95% CI, 85-99%)) than SR +/- SA (81% (95% CI, 71 91%)), but SR +/- SA had a higher specificity (84% (95% CI, 77-91%)). SR +/- SA + CA 125 and SR +/- SA + ROMA improved diagnostic accuracy, each diagnosing a third more malignant adnexal masses. In postmenopausal women, compared with SR +/- SA alone, SR +/- SA + CA 125 showed a net reclassification improvement (NRI) of 28.8% at an extra cost of ?13.00, while the extra cost for SR +/- SA + ROMA was ?33.71, with a comparable gain, in terms of NRI, as that of SR +/- SA + CA 125. CONCLUSIONS: In our study sample, SR +/- SA seems to be the best strategy to triage women with adnexal masses for surgical management. Among postmenopausal women, SR +/- SA + CA 125 increased the NRI at a reasonable extra cost. Our data do not justify the use of HE4 and ROMA in the initial triage of women with adnexal masses.

AB - OBJECTIVES: Bisphosphonates are widely used to treat bone diseases such as osteoporosis. However, they may cause osteonecrosis of the jaw. Here, we investigated whether in vivo exposure to bisphosphonates has a different effect on long bone and jaw osteoclasts, and on the turnover of these different bones. MATERIALS AND METHODS: Zoledronic acid (0.5 mg kg-1 weekly) was administered intraperitoneally to 3-month-old female mice for up to 6 months. The effects on the number of osteoclasts, bone mineralization and bone formation were measured in the long bones and in the jaw. RESULTS: Long-term treatment with zoledronic acid reduced the number of jaw bone marrow cells, without affecting the number of long bone marrow cells. Zoledronic acid treatment did not affect the number of osteoclasts in vivo. Yet, the bisphosphonate increased bone volume and mineral density of both long bone and jaw. Interestingly, 6 months of treatment suppressed bone formation in the long bones without affecting the jaw. Unexpectedly, we showed that bisphosphonates can cause molar root resorption, mediated by active osteoclasts. CONCLUSIONS: Our findings provide more insight into bone-site-specific effects of bisphosphonates and into the aetiology of osteonecrosis of the jaw. We demonstrated that bisphosphonates can stimulate osteoclast activity at the molar roots. PMID- 27706931 TI - Synthetic, Optical and Theoretical Study of Alternating Ethylenedioxythiophene Pyridine Oligomers: Evolution from Planar Conjugated to Helicoidal Structure towards a Chiral Configuration. AB - A series of alternating 3,4-ethylenedioxythiophene-alkynylpyridine oligomers (DA)n with increased solubility are synthesized and their photophysical properties and nonlinear optical properties are investigated. Their quadratic polarizabilities are determined from hyper-Rayleigh scattering experiments to obtain information on their conformations in solution. These chromophores, based on the alternation of electron-rich (D) and electron-deficient (A) moieties, exhibit optical properties that arise from the combination of dipolar and helicoidal features in the (DA)n homologue series where n=1-4. The transition from dipolar conjugated planar structures (n=1, 2) to helicoidal structures (n=3, 4) is clearly evidenced by results from symmetry-sensitive second-order nonlinear optical experiments. This suggests an approach towards highly efficient chiral chromophores for second-order nonlinear optics. Interestingly, this structural evolution also has significant impact on the photophysical properties: both absorption and fluorescence emission show bathochromic and hyperchromic shifts with increasing number of repeating units in the dipolar planar derivatives (n=1 2) but show saturation effects in the helicoidal structures (n=2-4). In addition, the helicoidal structures show sizeable two-photon absorption at 700-750 nm (40 100 GM) for compounds lacking either electron-donating or electron-withdrawing substituents.

AB - Benthic accumulations of filamentous, mat-forming bacteria occur throughout the oceans where bisulfide mingles with oxygen or nitrate, providing key but poorly quantified linkages between elemental cycles of carbon, nitrogen and sulfur. Here we used the autonomous underwater vehicle Sentry to conduct a contiguous, 12.5 km photoimaging survey of sea-floor colonies of filamentous bacteria between 80 and 579 m water depth, spanning the continental shelf to the deep suboxic waters of the Santa Barbara Basin (SBB). The survey provided >31 000 images and revealed contiguous, white-colored bacterial colonization coating > ~80% of the ocean floor and spanning over 1.6 km, between 487 and 523 m water depth. Based on their localization within the stratified waters of the SBB we hypothesize a dynamic and annular biogeochemical zonation by which the bacteria capitalize on periodic flushing events to accumulate and utilize nitrate. Oceanographic time series data bracket the imaging survey and indicate rapid and contemporaneous nitrate loss, while autonomous capture of microbial communities from the benthic boundary layer concurrent with imaging provides possible identities for the responsible bacteria. Based on these observations we explore the ecological context of such mats and their possible importance in the nitrogen cycle of the SBB.

AB - We report the successful fabrication of photoresponsive Janus particles (JPs) composed of an epoxy-based azo polymer and poly(methyl methacrylate) (PMMA). Two representative azo polymers, of which one polymer (BP-AZ-CN) has cyano groups as electron-withdrawing substituents on the azobenzene moieties and the other polymer (BP-AZ-CA) has carboxyl groups as the electron-withdrawing substituents, were adopted for the investigation. The nanoscaled JPs, with a narrow size distribution and different azo polymer/PMMA ratios, were fabricated through self assembly in solution and as dispersions. Upon irradiation with linearly polarized light (lambda=488 nm), two types of photoresponsive behavior were observed for JPs in the solid state. For JPs composed of BP-AZ-CN and PMMA, the light irradiation caused the azo-polymer component to be stretched along the light polarization direction. Conversely, for JPs composed of BP-AZ-CA and PMMA, the azo-polymer component became separated from PMMA component under the same irradiation conditions. These observations are valuable for a deeper understanding of the nature of self-assembly and photoinduced mass-transport at the nanometer scale. PMID- 27706935 TI - London Hybrid Exposure Model: Improving Human Exposure Estimates to NO2 and PM2.5 in an Urban Setting. AB - Here we describe the development of the London Hybrid Exposure Model (LHEM), which calculates exposure of the Greater London population to outdoor air pollution sources, in-buildings, in-vehicles, and outdoors, using survey data of when and where people spend their time. For comparison and to estimate exposure misclassification we compared Londoners LHEM exposure with exposure at the residential address, a commonly used exposure metric in epidemiological research. In 2011, the mean annual LHEM exposure to outdoor sources was estimated to be 37% lower for PM2.5 and 63% lower for NO2 than at the residential address. These decreased estimates reflect the effects of reduced exposure indoors, the amount of time spent indoors (~95%), and the mode and duration of travel in London. We find that an individual's exposure to PM2.5 and NO2 outside their residential address is highly correlated (Pearson's R of 0.9). In contrast, LHEM exposure estimates for PM2.5 and NO2 suggest that the degree of correlation is influenced by their exposure in different transport modes. Further development of the LHEM has the potential to increase the understanding of exposure error and bias in time-series and cohort studies and thus better distinguish the independent effects of NO2 and PM2.5.

AB - The transport length ltr and the mean free path le are determined for bulk and surface states in a Bi2Se3 nanoribbon by quantum transport and transconductance measurements. We show that the anisotropic scattering of spin-helical Dirac fermions results in a strong enhancement of ltr (~ 200 nm) and of the related mobility MUtr (~ 4000 cm2 V-1 s-1), which confirms theoretical predictions.1 Despite strong disorder, the long-range nature of the scattering potential gives a large ratio ltr/le ~ 8, likely limited by bulk/surface coupling. This suggests that the spin-flip length lsf ~ ltr could reach the micron size in materials with a reduced bulk doping and paves the way for building functionalized spintronic and ballistic electronic devices out of disordered 3D topological insulators.

AB - The simultaneous realization of high efficiency, stable spectra, high color rendering index (CRI), and low-efficiency roll-off in a fluorescent white organic light-emitting diode (WOLED) still remains a big challenge. Here, we demonstrate high-performance conventional fluorescent-dopant-based WOLEDs by strategic management of singlet and triplet excitons within an efficient emissive zone. This design consists of two separated red/green sub-EMLs with ultralow doping concentration and a sandwiched sub-EML doped with red and green fluorescent dyes at a relatively high concentration, which can harness all electrogenerated excitons and reduce the energy loss to the utmost extent. Accordingly, the resulting WOLED realizes an external quantum efficiency (EQE) of 18.2% with a maximum power efficiency of 44.6 lm W-1. At the practical luminance of 1000 cd m 2 for the lighting source, the EQE still remains as high as 16.2% with a CRI of 82 and stable color spectra. A comprehensive understanding of the device working mechanism is performed to guide design of efficient and stable fluorescent WOLEDs.

AB - A new multi-analyte immunoassay was designed to screen furaltadone metabolite 5 morpholinomethyl-3-amino-2-oxazolidone (AMOZ), malachite green (MG), and leucomalachite green (LMG) in aquatic products using a bispecific monoclonal antibody (BsMAb). Gradient drug mutagenesis methods were separately used to prepare an anti-3-nitrobenzaldehyde-derivatized AMOZ (3-NPAMOZ) hybridoma cell line that was hypoxanthine-guanine-phosphoribosyltransferase (HGRPT) deficient and an anti-LMG hybridoma cell line that was thymidine kinase (TK) deficient. BsMAb recognizing 3-NPAMOZ and LMG was generated using hybrid-hybridomas of HGRPT and TK deficient cell lines. For AMOZ and LMG, respectively, the BsMAb-based indirect competitive ELSIA (ic-ELISA) values of 1.7 ng/mL and 45.3 ng/mL and detection limits of 0.2 ng/mL and 4.8 ng/mL. To establish the ic-ELISA, 3-NPAMOZ derivatized from AMOZ with 3-nitrobenzaldehyde and LMG reduced from MG by potassium borohydride was recognized by BsMAb. Recoveries of AMOZ, MG, and LMG in aquatic products were satisfactory and correlated with HPLC analysis. Thus, the multi-analyte ic-ELISA is suitable for rapid quantification of AMOZ, MG and LMG in aquatic products. PMID- 27706932 TI - Do specific NMDA receptor subunits act as gateways for addictive behaviors? AB - Addiction to alcohol and drugs is a major social and economic problem, and there is considerable interest in understanding the molecular mechanisms that promote addictive drives. A number of proteins have been identified that contribute to expression of addictive behaviors. NMDA receptors (NMDARs), a subclass of ionotropic glutamate receptors, have been of particular interest because their physiological properties make them an attractive candidate for gating induction of synaptic plasticity, a molecular change thought to mediate learning and memory. NMDARs are generally inactive at the hyperpolarized resting potentials of many neurons. However, given sufficient depolarization, NMDARs are activated and exhibit long-lasting currents with significant calcium permeability. Also, in addition to stimulating neurons by direct depolarization, NMDARs and their calcium signaling can allow strong and/or synchronized inputs to produce long term changes in other molecules (such as AMPA-type glutamate receptors) which can last from days to years, binding internal and external stimuli in a long-term memory trace. Such memories could allow salient drug-related stimuli to exert strong control over future behaviors and thus promote addictive drives. Finally, NMDARs may themselves undergo plasticity, which can alter subsequent neuronal stimulation and/or the ability to induce plasticity. This review will address recent and past findings suggesting that NMDAR activity promotes drug- and alcohol-related behaviors, with a particular focus on GluN2B subunits as possible central regulators of many addictive behaviors, as well as newer studies examining the importance of non-canonical NMDAR subunits and endogenous NMDAR cofactors. PMID- 27706940 TI - Direct Observation of Electron-Phonon Coupling and Slow Vibrational Relaxation in Organic-Inorganic Hybrid Perovskites. AB - Quantum and dielectric confinement effects in 2D hybrid perovskites create excitons with a binding energy exceeding 150 meV. We exploit the large exciton binding energy to study exciton and carrier dynamics as well as electron-phonon coupling in hybrid perovskites using absorption and photoluminescence (PL) spectroscopies. At temperatures below 75 K, we resolve splitting of the excitonic absorption and PL into multiple regularly-spaced resonances every 40-46 meV, consistent with electron-phonon coupling to phonons located on the organic cation. We also resolve resonances with a 14 meV spacing, in accord with coupling to phonons with mixed organic and inorganic character, and these assignments are supported by density-functional theory calculations. Hot exciton PL and time resolved PL measurements show that vibrational relaxation occurs on a picosecond timescale competitive with that for PL. At temperatures above 75 K, excitonic absorption and PL exhibit homogeneous broadening. While absorption remains homogeneous, PL becomes inhomogeneous below 75K, which we speculate is caused by the formation and subsequent dynamics of a polaronic exciton.

AB - The stereospecific reductive cross-electrophile coupling reaction of 2-vinyl-4 halotetrahydropyrans for vinylcyclopropane synthesis is reported. The nickel catalyzed reaction occurs with both alkyl fluorides and alkyl chlorides. To the best of our knowledge, this is the first reported cross-electrophile coupling reaction of an alkyl fluoride. Ring contraction proceeds with high stereospecificity, providing selective synthesis of either diastereomer of di- and trisubstituted cyclopropanes. The utility of this methodology is demonstrated by several synthetic applications including the synthesis of the natural product dictyopterene A. 2-Vinyl-4-fluorotetrahydrofurans also undergo stereospecific ring contractions, providing access to synthetically useful hydroxymethyl cyclopropanes.

During PH, the pulmonary artery undergoes remodelling, which is caused by pulmonary vascular smooth muscle cell proliferation. CyclinD1 regulates cell proliferation. This study investigated the role of cyclinD1 in the development of PH in broilers, and which bioactivators and signalling pathway are involved in the pathological process. The PH group contained 3-4-week-old broilers with clinical PH, and the healthy group broilers from the same flock without PH. Histopathology indicated pulmonary arterial walls were thicker in the PH group compared with the healthy group. Target gene expressions of macrophage migration inhibitory factor (MIF), extracellular signal-regulated kinase (ERK), and cyclinD1 detected by quantitative real-time PCR were upregulated in the PH group compared with the healthy group. Immunohistochemistry showed MIF, phosphorylated ERK (p-ERK) and cyclinD1 were present on pulmonary vascular walls; MIF was present in the cytoplasm of arterial endothelial cells and smooth muscle cells; p ERK and cyclinD1 were present in smooth muscle cell cytoplasm. Western blotting demonstrated that MIF, p-ERKand cyclinD1 levels were significantly higher (P < 0.01) in the PH group compared with the healthy group. In summary, increased MIF in PH broiler pulmonary arteries upregulated cyclinD1 via the ERK signalling pathway to induce pulmonary vascular smooth muscle cell proliferation, causing pulmonary artery remodelling and hypertension. PMID- 27706944 TI - Phytochemical Inhibition of Multidrug Resistance Protein-1 as a Therapeutic Strategy for Hemangioendothelioma. AB - AIMS: Hemangiomas are endothelial cell tumors and the most common soft tissue tumors in infants. They frequently cause deformity and can cause death. Current pharmacologic therapies have high-risk side-effect profiles, which limit the number of children who receive treatment. The objectives of this work were to identify the mechanisms through which standardized berry extracts can inhibit endothelial cell tumor growth and test these findings in vivo. RESULTS: EOMA cells are a validated model that generates endothelial cell tumors when injected subcutaneously into syngeneic (129P/3) mice. EOMA cells treated with a blend of powdered natural berry extracts (NBE) significantly inhibited activity of multidrug resistance protein-1 (MRP-1) compared to vehicle controls. This resulted in nuclear accumulation of oxidized glutathione (GSSG) and apoptotic EOMA cell death. When NBE-treated EOMA cells were injected into mice, they generated smaller tumors and had a higher incidence of apoptotic cell death compared to vehicle-treated EOMA cells as demonstrated by immunocytochemistry. Kaplan-Meier survival curves for tumor-bearing mice showed that NBE treatment significantly prolonged survival compared to vehicle-treated controls. INNOVATION: These are the first reported results to show that berry extracts can inhibit MRP-1 function that causes apoptotic tumor cell death by accumulation of GSSG in the nucleus of EOMA cells where NADPH oxidase is hyperactive and causes pathological angiogenesis. CONCLUSIONS: These findings indicate that berry extract inhibition of MRP-1 merits consideration and further investigation as a therapeutic intervention and may have application for other cancers with elevated MRP-1 activity.

AB - OBJECTIVE: A clinical evaluation of the intrafraction and interfraction setup accuracy of a novel thermoplastic mould immobilization device and patient position in early-stage lung cancer being treated with stereotactic radiotherapy at the Beatson West of Scotland Cancer Centre, Glasgow, UK. METHODS: 35 patients were immobilized in a novel, arms-down position, with a four-point KlarityTM (Klarity Medical Products, Ohio, US) clear thermoplastic mould fixed to a SinMed (CIVCO Medical solutions, lowa, US) head and neck board. A knee support was also used for patient comfort and support. Pre- and post-treatment kilovoltage cone beam CT (CBCT) images were fused with the planning CT scan to determine intra- and interfraction motion. A total of 175 CBCT scans were analysed in the longitudinal, vertical and lateral directions. RESULTS: The mean intrafraction errors were 0.05 +/- 0.77 mm (lateral), 0.44 +/- 1.2 mm (superior-inferior) and 1.44 +/- 1.35 mm (anteroposterior), respectively. Mean composite three dimensional displacement vector was 2.14 +/- 1.2 mm. Interfraction errors were 0.66 +/- 2.35 mm (lateral), -0.13 +/- 3.11 mm (superior-inferior) and 0.00 +/- 2.94 mm (anteroposterior), with three-dimensional vector 4.08 +/- 2.73 mm. CONCLUSION: Setup accuracy for lung image-guided stereotactic ablative radiotherapy using a unique immobilization device, where patients have arms by their sides, has been shown to be safe and favourably comparable to other published setup data where more complex and cumbersome devices were utilised. There was no arm toxicity reported and low arm doses. Advances in knowledge: We report on the accuracy of a novel patient immobilization device. PMID- 27706947 TI - Simultaneous integrated boost (SIB) of the parametrium and cervix in radiotherapy for uterine cervical carcinoma: a dosimetric study using a new alternative approach. AB - OBJECTIVE: To compare the dose distributions of intensity-modulated radiotherapy (IMRT) and volumetric-modulated arc therapy (VMAT) using the simultaneous integrated boost (SIB) technique with that of the traditional midline block (MB) technique for boosting the parametrium in patients with cervical cancer. METHODS: Treatment plans using VMAT or IMRT with the SIB technique (VMAT-SIB and IMRT-SIB) and IMRT followed by the MB technique (IMRT-MB) were generated for each of the 10 patients with cervical cancer. For the SIB plans, 45-Gy and 50-Gy dose levels in 25 equal fractions were set for the pelvis planning target volume 45 (PTV45) and the parametrial boost volume (PTV50), respectively. For the IMRT-MB plans, the parametrium was sequentially boosted with the MB technique (5.4 Gy in three fractions) after pelvic IMRT (PTV45). RESULTS: Volume receiving 100% of the prescribed dose or more coverage of the PTV50 was significantly better for VMAT SIB and IMRT-SIB than that for IMRT-MB (99.08 and 99.31% compared with 91.79%, respectively; p < 0.05). VMAT-SIB and IMRT-SIB both generated significantly greater doses to the organs at risk (OARs) except for the volume receiving 50 Gy or more doses, which were significantly lower for the bladder and bowel. Comparable results were achieved with VMAT-SIB and IMRT-SIB. CONCLUSION: The VMAT SIB and IMRT-SIB techniques are promising in terms of dose distributions and tumour coverage, although these approaches might result in slightly higher doses of radiation to the OARs. Advances in knowledge: This is the first study to examine the feasibility of the SIB technique using IMRT or VMAT to boost the parametrium. The techniques dosimetrically produced better target coverage but resulted in slightly higher doses to the OARs. PMID- 27706948 TI - Which Should be Preferred for Moderate-Size Kidney Stones? Ultramini Percutaneous Nephrolithotomy or Retrograde Intrarenal Surgery? AB - PURPOSE: Comparison of effectiveness and safety of ultramini percutaneous nephrolithotomy (UMPNL) and retrograde intrarenal surgery (RIRS) in treatment of moderate-sized renal stones. MATERIAL AND METHODS: The patients scheduled for surgery attributable to renal stones with the greatest diameter of 10 to 25 mm were prospectively analyzed. Patients were randomized into groups with tossing a coin method. The patients who had UMPNL and RIRS were defined as Group I and Group II, respectively. The groups were compared for demograhic data, stone characteristics, operative and postoperative data, stone-free status, and the complications. Student's t-test and Pearson's Chi square tests were used for statistical analysis. p < 0.05 was considered as statistically significant. RESULTS: There were 30 patients in Group I, and 43 patients in Group II. The groups were similar for age, gender, side of the stone, and surface area characteristics of the stone (p = 0.194, p = 0.470, p = 0.990, and p = 0.487, respectively). Stone-free rate was 80% (n = 24) in UMPNL, and 74.4% (n = 32) in RIRS (p = 0.579). Modified Clavien Classification Grade 1 to 2 and 3A to 3B complications were similar in two groups (p = 0.959 and p = 0.192, respectively). Comparison of stone-free rates was 93.3% in UMPNL, and 42.9% in RIRS groups for lower pole stones (p = 0.009). Groups I and II were significantly different for visual analog scale scores for postoperative pain (4.73 +/- 1.25 vs 2.30 +/- 1.12), hospital stay (2.46 +/- 3.02 vs 1.37 +/- 1.48 days), and time to return to normal daily life (11.26 +/- 5.55 vs 6.65 +/- 4.30 days) (p < 0.001, p < 0.001, and p < 0.001, respectively). CONCLUSION: Both UMPNL and RIRS procedures are effective and safe methods in treatment of middle-sized renal stones. However, UMPNL is more effective than RIRS in treatment of lower pole stones. RIRS is more advantageous when loss from work is taken into consideration. PMID- 27706949 TI - Age-related racial disparities in prostate cancer patients: A systematic review. AB - OBJECTIVE: Prostate cancer mortality rates have decreased over recent decades, but racial disparities in prostate cancer survival still present as a serious challenge. These disparities may be impacted by age; in fact, African-American men younger than age 65 have prostate cancer mortality rates nearly three times greater than that of White men. Therefore, a systematic literature review was conducted in Medline and EMBASE databases focusing on articles comparing survival and mortality rates for prostate cancer patients across age and race. DESIGN: Articles included were based on the following criteria: (1) included African American and White prostate cancer patients residing in the US; (2) measured racial disparities across distinct age categories with at least one category below and one above age 65; and (3) addressed racial disparities in terms of overall survival or mortality. RESULTS: Twenty eight articles compared survival and mortality disparities between African-American and White prostate cancer patients across different age categories. Of the 28 articles, 19 articles (68%) showed disparities decreased with age, 8 articles (29%) showed disparities constant with age, and 1 article (3%) showed disparities increased with age. CONCLUSIONS: More often the survival and mortality gap between African-American and White prostate cancer patients decreases with age. Additional studies are needed to elucidate other factors that may influence racial disparities in prostate cancer patients. These results provide insight into the racial disparities in prostate cancer and suggest more resources should be directed towards decreasing the disparity gap in younger prostate cancer patients. PMID- 27706950 TI - Deep inspiration breath-hold radiotherapy for lung cancer: impact on image quality and registration uncertainty in cone beam CT image guidance. AB - OBJECTIVE: We investigated the impact of deep inspiration breath-hold (DIBH) and tumour baseline shifts on image quality and registration uncertainty in image guided DIBH radiotherapy (RT) for locally advanced lung cancer. METHODS: Patients treated with daily cone beam CT (CBCT)-guided free-breathing (FB) RT had an additional CBCT in DIBH at three fractions. These CBCT scans were offline rigidly registered (on tumour) to FB and DIBH CT scans acquired at planning. All registrations were repeated to evaluate the intraobserver uncertainty. CBCT scans were scored on degree of streak artefacts and visualization of tumour and anatomical structures. We examined the impact of tumour baseline shift between consecutive DIBHs on CBCT image quality. RESULTS: CBCT scans from 15 patients were analysed. Intraobserver image registration uncertainty was approximately 2 mm in both FB and DIBH, except for the craniocaudal direction in FB, where it was >3 mm. On the 31st fraction, the intraobserver uncertainty increased compared with the second fraction. This increase was more pronounced in FB. Image quality scores improved in DIBH compared with FB for all parameters in all patients. Simulated tumour baseline shifts <=2 mm did not affect the CBCT image quality considerably. CONCLUSION: DIBH CBCT improved image quality and reduced registration uncertainty in the craniocaudal direction in image-guided RT of locally advanced lung cancer. Baseline shifts <=2 mm in DIBH during CBCT acquisition did not affect image quality. Advances in knowledge: DIBH RT has dosimetric advantages over FB; this work demonstrates an additional benefit of DIBH in terms of registration accuracy because of improved image quality. PMID- 27706951 TI - Inhibition of pancreatic lipase and amylase by extracts of different spices and plants. AB - The aim of this study is to search new anti-obesity and anti-diabetic agents from plant and spices crude extracts as alternative to synthetic drugs. The inhibitory effect of 72 extracts was evaluated, in vitro, on lipase and amylase activities. Aqueous extracts of cinnamon and black tea exhibited an appreciable inhibitory effect on pancreatic amylase with IC50 values of 18 and 87 MUg, respectively. Aqueous extracts of cinnamon and mint showed strong inhibitory effects against pancreatic lipase with IC50 of 45 and 62 MUg, respectively. The presence of bile salts and colipase or an excess of interface failed to restore the lipase activity. Therefore, the inhibition of pancreatic lipase, by extracts of spices and plants, belongs to an irreversible inhibition. Crude extract of cinnamon showed the strongest anti-lipase and anti-amylase activities which offer a prospective therapeutic approach for the management of diabetes and obesity.

PMID- 27706953 TI - Foam cell formation by particulate matter (PM) exposure: a review. AB - Increasing evidence suggests that exposure of particulate matter (PM) from traffic vehicles, e.g., diesel exhaust particles (DEP), was associated with adverse vascular effects, e.g., acceleration of atherosclerotic plaque progression. By analogy, engineered nanoparticles (NPs) could also induce similar effects. The formation of lipid laden foam cells, derived predominately from macrophages and vascular smooth muscle cells (VSMC), is closely associated with the development of atherosclerosis and adverse vascular effects. We reviewed current studies about particle exposure-induced lipid laden foam cell formation. In vivo studies using animal models have shown that exposure of air pollution by PM promoted lipid accumulation in alveolar macrophages or foam cells in plaques, which was likely associated with pulmonary inflammation or systemic oxidative stress, but not blood lipid profile. In support of these findings, in vitro studies showed that direct exposure of cultured macrophages to DEP or NP exposure, with or without further exposure to external lipids, promoted intracellular lipid accumulation. The mechanisms remained unknown. Although a number studies found increased reactive oxygen species (ROS) or an adaptive response to oxidative stress, the exact role of oxidative stress in mediating particle-induced foam cell formation requires future research. There is currently lack of reports concerning VSMC as a source for foam cells induced by particle exposure. In the future, it is necessary to explore the role of foam cell formation in particle exposure-induced atherosclerosis development. In addition, the formation of VSMC derived foam cells by particle exposure may also need extensive studies. PMID- 27706954 TI - Sexual functioning and quality of life of Hong Kong Chinese women with infertility problem. AB - Infertility is estimated to affect 10-15% of couples in industrialized countries and many of them are under tremendous stress. Stress can lead to poor quality of life and sexual dysfunction in general, but little is known about their prevalence in infertile women. We, therefore, conducted this cross-sectional survey in two primary care subfertility clinics between August 2012 and April 2013. A total of 159 women completed two validated Chinese questionnaires: Female Sexual Function Index and core Fertility Quality of Life. The overall Female Sexual Function Index score (mean +/- SD) of the whole group was 24.99 +/- 4.22. Using the urban Chinese cut-off, the prevalence of female sexual dysfunction, low desire, arousal disorder, lubrication disorder, orgasmic disorder and sexual pain were 32.5%, 15.7%, 19.3%, 22.3%, 33.1% and 15.1%. The core Fertility Quality of Life score of the whole group was 59.76 +/- 13.59 and the subgroup of infertile women with sexual dysfunction (n = 50) had significantly lower mean core Fertility Quality of Life score than those without sexual dysfunction (n = 109) (55.03 versus 61.88) (p = 0.005). Among the subscales, the relational score had the strongest correlation with sexual dysfunction. Infertile women with sexual dysfunction had significantly worse quality of life especially in the relational aspect. PMID- 27706957 TI - ?

PMID- 27706955 TI - Salt and obesity: a systematic review and meta-analysis of observational studies. AB - BACKGROUND: Existing research has investigated the association between sodium intake and obesity. We aim to conduct a systematic review and meta-analysis of reported evidence regarding the association between sodium intake and obesity. METHODS: Multiple electronic databases (PubMed, Scopus, and Google Scholar) were searched for observational studies published until August 2016. A systematic literature review identified 11 cohort and 21 cross-sectional studies. RESULT: Among the 32 studies identified in the systematic literature search, only 18 cross-sectional reports had sufficient data to be included in the meta-analysis. Higher sodium consumption was associated with greater BMI (weighed mean difference (WMD) = 1.24 kg/m2, 95%CI: 0.80, 1.67; I2 = 98.4%; p < .0001), and higher sodium intake was associated with 4.75 cm (95%CI: 3.25, 6.25; 90.8%; p <.0001) greater waist circumference (WC). CONCLUSION: The present meta-analysis suggests that sodium consumption was associated with greater BMI and WC. PMID- 27706956 TI - A comparative assessment of the acute inhalation toxicity of vanadium compounds. AB - Vanadium compounds have become important in industrial processes, resulting in workplace exposure potential and are present in ambient air as a result of fossil fuel combustion. A series of acute nose-only inhalation toxicity studies was conducted in both rats and mice in order to obtain comparative data on the acute toxicity potential of compounds used commercially. V2O3, V2O4, and V2O5, which have different oxidation states (+3, +4, +5, respectively), were delivered as micronized powders; the highly water-soluble and hygroscopic VOSO4 (+4) could not be micronized and was instead delivered as a liquid aerosol from an aqueous solution. V2O5 was the most acutely toxic micronized powder in both species. Despite its lower overall percentage vanadium content, a liquid aerosol of VOSO4 was more toxic than the V2O5 particles in mice, but not in rats. These data suggest that an interaction of characteristics, i.e., bioavailability, solubility and oxidation state, as well as species sensitivity, likely affect the toxicity potential of vanadium compounds. Based on clinical observations and gross necropsy findings, the lung appeared to be the target organ for all compounds. The level of hazard posed will depend on the specific chemical form of the vanadium. Future work to define the inhalation toxicity potential of vanadium compounds of various oxidation states after repeated exposures will be important in understanding how the physico-chemical and biological characteristics of specific vanadium compounds interact to affect toxicity potential and the potential risks posed to human health.

AB - Propofol lipid emulsion (PLE) is a nanosized sedative, and it is used with a combination of salted antalgic prodrug, fentanyl citrate (FC). To illustrate the synergistic effect of mixing, we compared the sedation/analgesia resulting from simultaneous and sequential administration in surgically induced abortion (No. ChiCTR-IPC-15006153). Simultaneous group showed lower bispectral index, blood pressure, and heart rate, when cannula was inserted into the uterus. It also showed less frequency of hypertension, sinus tachycardia, movement, pain at the injection site, and additional FC. Therefore, premixing of PLE and FC enhanced the sedation and analgesia; stabilized the hemodynamics; lessened the incidence of movement and injection pain; and reduced the requirement of drugs. PMID- 27707002 TI - A new formulation of slight compressibility for arterial tissue and its Finite Element implementation. AB - In order to avoid the numerical difficulties in locally enforcing the incompressibility constraint using the displacement formulation of the Finite Element Method, slight compressibility is typically assumed when simulating the mechanical response of arterial tissue. The current standard method of accounting for slight compressibility of hyperelastic soft tissue assumes an additive decomposition of the strain-energy function into a volumetric and a deviatoric part. This has been shown, however, to be inconsistent with the linear theory and results in cubes retaining their cuboid shape under hydrostatic tension and compression, which seems at variance with the reinforcement of arterial tissue with two families of collagen fibres. A remedy for these defects is proposed here, a solution which generalises the current standard model of slight compressibility to include two additional terms, one of which is quadratic in the [Formula: see text] invariants and the other quadratic in [Formula: see text]. Experimental data are used to motivate typical values for the associated material constants of these additional terms. Some simulations are performed to allow contrasts and comparisons to be made between the current standard model of slight compressibility and its generalisation proposed here.

PMID- 27707004 TI - N-tuple topological/geometric cutoffs for 3D N-linear algebraic molecular codifications: variability, linear independence and QSAR analysis. AB - Novel N-tuple topological/geometric cutoffs to consider specific inter-atomic relations in the QuBiLS-MIDAS framework are introduced in this manuscript. These molecular cutoffs permit the taking into account of relations between more than two atoms by using (dis-)similarity multi-metrics and the concepts related with topological and Euclidean-geometric distances. To this end, the kth two-, three- and four-tuple topological and geometric neighbourhood quotient (NQ) total (or local-fragment) spatial-(dis)similarity matrices are defined, to represent 3D information corresponding to the relations between two, three and four atoms of the molecular structures that satisfy certain cutoff criteria. First, an analysis of a diverse chemical space for the most common values of topological/Euclidean geometric distances, bond/dihedral angles, triangle/quadrilateral perimeters, triangle area and volume was performed in order to determine the intervals to take into account in the cutoff procedures. A variability analysis based on Shannon's entropy reveals that better distribution patterns are attained with the descriptors based on the cutoffs proposed (QuBiLS-MIDAS NQ-MDs) with regard to the results obtained when all inter-atomic relations are considered (QuBiLS-MIDAS KA-MDs - 'Keep All'). A principal component analysis shows that the novel molecular cutoffs codify chemical information captured by the respective QuBiLS MIDAS KA-MDs, as well as information not captured by the latter. Lastly, a QSAR study to obtain deeper knowledge of the contribution of the proposed methods was carried out, using four molecular datasets (steroids (STER), angiotensin converting enzyme (ACE), thermolysin inhibitors (THER) and thrombin inhibitors (THR)) widely used as benchmarks in the evaluation of several methodologies. One to four variable QSAR models based on multiple linear regression were developed for each compound dataset following the original division into training and test sets. The results obtained reveal that the novel cutoff procedures yield superior performances relative to those of the QuBiLS-MIDAS KA-MDs in the prediction of the biological activities considered. From the results achieved, it can be suggested that the proposed N-tuple topological/geometric cutoffs constitute a relevant criteria for generating MDs codifying particular atomic relations, ultimately useful in enhancing the modelling capacity of the QuBiLS-MIDAS 3D-MDs.

Orlistat is an FDA-approved antiobesity drug which is a potent inhibitor of intestinal lipases. OBJECTIVE: In the current study, orlistat was evaluated for its genotoxic potential in human lymphocyte cells in vitro and was compared with that of another antiobesity drug sibutramine, presently withdrawn from market due its undesirable health effects. Caffeine intake may be an additional burden in people using anorectic drugs, therefore, further work is needed to be carried out to evaluate the possible effects of caffeine on orlistat-induced DNA damage. MATERIALS AND METHODS: Human lymphocytes were exposed to orlistat (250, 500 and 1000 MUg/ml), sibutramine (250, 500 and 1000 MUg/ml) and caffeine (25, 50, 75, 100, 125 and 150 MUg/ml) to assess their genotoxicity by comet assay in vitro. In addition, lymphocytes were co-incubated with caffeine (50, 75 and 100 MUg/ml) and a single concentration of orlistat (250 MUg/ml). RESULTS: Orlistat and sibutramine were genotoxic at all concentrations tested, sibutramine being more genotoxic. Caffeine was found to be genotoxic at concentrations 125 MUg/ml and above. Co-treatment of orlistat with non-genotoxic concentrations (50, 75 and 100 MUg/ml) of caffeine lead to a decrease in DNA damage. DISCUSSION AND CONCLUSION: Orlistat can induce DNA damage in human lymphocytes in vitro and caffeine was found to reduce orlistat-induced genotoxicity. PMID- 27707006 TI - Background and episodic breathlessness in advanced cancer patients followed at home. AB - BACKGROUND: The aim of this study was to assess the phenomenon of episodic breathlessness in advanced cancer patients followed by palliative care services at home. METHODS: A consecutive sample of patients with advanced cancer, admitted to home care for a period of six months, was surveyed. The presence of background breathlessness and episodic breathlessness, their intensity, and drugs used for their treatment were collected. Factors inducing episodic breathlessness, and its influence on daily activities were investigated. RESULTS: Three hundred forty seven advanced cancer patients admitted to home palliative care were surveyed. The prevalence of breathlessness was 35.3%. The mean intensity of breathlessness was 3.8 (SD 1.96), out of a maximum score of 10 for worst imaginable. Sixty patients (49.2%) were receiving drugs for background breathlessness. In the multivariate analysis the risk of breathlessness increased with cardiovascular disease, chronic obstructive pulmonary disease, and lung cancer while it decreased in patients with a better performance status. The prevalence of episodic breathlessness in patients with background breathlessness was 79.5% and its mean intensity was 7.1 (SD 1.5, range 2-10). The mean duration of episodic breathlessness was 28.6 minutes (SD 47.1, range 1-300 minutes). Forty-three patients (44.3%) were receiving one or more drugs as needed. The majority of episodic breathlessness events were triggered by activity. Episodic breathlessness was interfering with daily activities in 65 patients (67%). Episodic breathlessness wasn't associated with any variable taken into consideration. CONCLUSION: This study showed that episodic breathlessness frequently occurs in advanced cancer patients admitted to home care, is severe in intensity, is triggered in most cases by activity, and is characterized by a short duration which requires rapid measures.

AB - The aim of this study was to evaluate phenolics profile and antioxidant activity of Stachys lavandulifolia. Total phenolics (TP), total flavonoids (TF), DPPH* assay (IC50), ferric ion reducing antioxidant power (FRAP) and total antioxidant capacity (TAC) of the methanolic extract were measured. The content of TP, TF, IC50, FRAP and TAC, were obtained as 16.59 gallic acid equiv./g dry matter (DM), 4.48 mg quercetin equiv./g DM, 2.07 (MUg/mL), 0.014 (absorbance/mg phenolic) and 14.61 (mg BHT equiv./g DM), respectively. The results showed that S. lavandulifolia, compared to other species of Stachys, had moderate TP content with desirable antioxidant activity. Subsequently, 59 various phenolic compounds were identified and confirmed in the methanolic extract of S. lavandulifolia using high mass accuracy by MS2 experiments. The compounds consisted of 6 hydroxybenzoic acids and hydroxybenzoic aldehydes, 9 hydroxycinnamic acids, 1 coumarin, 32 flavonoids, 3 lignans, 2 stilbenes, 3 tannins and 3 other phenolics.

AB - Multiple disorders once jointly conceived as "nervous diseases" became segregated by the distinct institutional traditions forged in neurology and psychiatry. As a result, each field specialized in the study and treatment of a subset of such conditions. Here we propose new avenues for interdisciplinary interaction through a triangulation of both fields with social neuroscience. To this end, we review evidence from five relevant domains (facial emotion recognition, empathy, theory of mind, moral cognition, and social context assessment), highlighting their common disturbances across neurological and psychiatric conditions and discussing their multiple pathophysiological mechanisms. Our proposal is anchored in multidimensional evidence, including behavioral, neurocognitive, and genetic findings. From a clinical perspective, this work paves the way for dimensional and transdiagnostic approaches, new pharmacological treatments, and educational innovations rooted in a combined neuropsychiatric training. Research-wise, it fosters new models of the social brain and a novel platform to explore the interplay of cognitive and social functions. Finally, we identify new challenges for this synergistic framework. PMID- 27707009 TI - An inverse problem in estimating the laser irradiance and thermal damage in laser irradiated biological tissue with a dual-phase-lag model. AB - The aim of this study is to solve an inverse heat conduction problem to estimate the unknown time-dependent laser irradiance and thermal damage in laser irradiated biological tissue from the temperature measurements taken within the tissue. The dual-phase-lag model is considered in the formulation of heat conduction equation. The inverse algorithm used in the study is based on the conjugate gradient method and the discrepancy principle. The effect of measurement errors and measurement locations on the estimation accuracy is also investigated. Two different examples of laser irradiance are discussed. Results show that the unknown laser irradiance and thermal damage can be predicted precisely by using the present approach for the test cases considered in this study.

PMID- 27707011 TI - A Multi-locus Approach to Characterization of Major Quantitative Trait Loci Influencing Hb F Regulation in Chinese beta-thalassemia Carriers. AB - Genetic association studies showed that Hb F is under the influence of major quantitative trait loci (QTL) in beta-thalassemia (beta-thal) carriers. Single nucleotide polymorphisms (SNPs) at three major QTLs, BCL11A, HBS1L-MYB intergenic region and XmnI-HBG2 were individually validated in univariate models. However, their relative effect sizes on Hb F regulation are unknown. We genotyped 99 Chinese beta-thal carriers for the three major QTLs and performed genetic association studies using three different statistical models, including mass univariate analysis, multivariate linear regression and partial least square regression structural equation modeling (PLS-SEM). Performances of the three models were compared and effect sizes of the three QTLs in a multivariate model were assessed. Traditional mass univariate analysis and multivariate linear regression showed limited statistical power in our small cohort and the latter was constrained by multicollinearity. Partial least structural equation modeling showed significant positive associations of each QTL (p <0.05) with Hb F regulation, together explained 34.4% of variance. The HBS1L-MYB intergenic region polymorphism (HMIP) demonstrated the highest effect on Hb F prediction with effect size f2 0.294. PLS-SEM offered a statistically powerful multivariate model for multi-locus genetic association studies. We reproduced findings of previous studies with a much smaller cohort and demonstrated HMIP as the strongest regulator of Hb F in Chinese beta-thal carriers. PMID- 27707012 TI - Working memory function is linked to trauma exposure, independently of post traumatic stress disorder symptoms. AB - INTRODUCTION: The purpose of the study was to examine how working memory (WM) may be related to exposure to potentially traumatic events and symptoms of post traumatic stress disorder (PTSD). METHOD: In four studies, we measured WM function using adaptations of the running span and the reading span tasks. We compared the performance of women reporting experiences of sexual abuse to control participants (total n = 144 controls and 84 victims). We measured severity of the sexual abuse experiences as well as exposure to general life stress. RESULTS: In all studies, trauma-exposed participants showed significantly lower WM function compared to control participants. In addition to traditional null hypothesis testing, we used a mini-meta analysis to estimate the combined estimated effect size of this difference, which was in the moderate range (d = 0.43 with 0.15-0.70 95% confidence interval). Regression equations showed that PTSD symptoms did not mediate the relationship between trauma exposure and WM function. CONCLUSIONS: Our results show that trauma exposure per se can be associated with important cognitive correlates even in individuals who do not develop psychopathological reactions.

AB - PURPOSE: To clarify whether initial base excision repair processes at clustered DNA damage sites comprising multiple base lesions affect subsequent excision processes via the formation of additional strand breaks by glycosylase and apurinic/apyrimidinic (AP) endonuclease base excision enzymes. MATERIALS AND METHODS: Plasmid DNA (pUC18) as a model DNA molecule was exposed to high-linear energy-transfer (LET) ionizing radiation (He2+ or C6+ ions) or low-LET ionizing radiation (X-rays) under various conditions to produce varied radical-scavenging effects. pUC18 was then treated sequentially or simultaneously with two bacterial base excision enzymes (glycosylases), namely, endonuclease III and formamidopyrimidine-DNA glycosylase, which convert pyrimidine (or abasic [AP] site) and purine (or AP site) lesions to single-strand breaks (SSB), respectively. Yields of additional SSB or double-strand breaks (DSB) as digestion products were examined after changing the order of enzymatic treatment. RESULTS: There were few differences among the enzymatic treatments, indicating that treatment order did not affect the final yields of additional SSB or DSB formed by glycosylase activity. This suggests that of the total damage, the fraction of clustered damage sites with a persistent base lesion dependent on the order of glycosylase treatment was insignificant if present. CONCLUSION: Base lesion clusters induced by high- or low-LET radiation appear three or more base pairs apart, and are promptly converted to a DSB by glycosylase, regardless of the order of enzymatic treatment.

AB - Though there are many albumin-based drug delivery systems (ABDDS) in the market, it is not known whether ABDDS can be applied across all chemical classes. In this study, we applied ABDDS to a poorly water-soluble drug betulinic acid (BA) to improve its aqueous solubility. Monomeric albumin-bound BA (ABBns) nanoparticles can be fabricated in the range of 10-20 nm. BA self-assembled with HSA at 0.1:1 to 2:1 molar ratio within 0.5 h in phosphate buffer pH 7.4 and 8.4. Approximately, 85-90% BA could be loaded onto HSA in the presence of Tween 20 (T20) and sodium cholate (NaC). The release of BA from ABBns was linear over 5 days. In conclusion, for poorly water-soluble acidic drugs, a suitable solubiliser can release the drug from HSA binding site, depending on the aggregation number and affinity of the solubiliser for the HSA binding site.

AB - Studies employing Cecropia glaziovii Snethl leaves have shown great potential in regard to their antiviral activity, mainly related to the phenolic compounds present in this species. The main goal of this work is to combine the therapeutic potential of this species with new technological strategies targeted at the development of an herbal nanoparticulate system for the preparation of a phytotherapeutic formulation. Poly (lactic-co-glycolic acid) nanoparticles containing the enriched flavonoid fraction of Cecropia glaziovii Snethl were developed through a study for the choice of preparation technique, amount of drug and surfactants used. These nanostructured systems were characterized by particle size, polydispersity, zeta potential, encapsulation efficiency and drug-loading capacity. A stability study of the formulations was conducted at room temperature over a period of 60 days. The optimal formulation that best fit the characteristics of the encapsulated material was determined. Sorbitan monooleate and the poloxamer 188 resulted in better colloidal stability, added to the organic and aqueous phases, respectively. These findings suggest that in the field of nanoparticles stability, it is important to evaluate the composition of the nanoparticulate system. This work highlights the importance of the optimization process, searching for a good formulation with suitable structural stabilization.

The aim of this study is to demonstrate the effects of cilostazol on TRAM flap viability in a rat TRAM model. METHODS: Twenty-four Wistar rats were used. They were divided into four groups. Rats in Group 1 were applied TRAM flap. In Group 2, cilostazol 30 mg/kg was administered to rats via oral gavage 3 hours before the flap surgery. After the flap surgery, cilostazol 30 mg/kg was administered via oral gavage twice a day for 7 days. In Group 3 before the flap surgery, cilostazol 30 mg/kg was administered via oral gavage twice a day for 7 days, and treatment continued for 7 more days after the flap surgery. In Group 4 before the flap surgery, cilostazol 30 mg/kg was administered via oral gavage twice a day for 7 days and treatment was discontinued after the flap surgery. RESULT: The mean necrosis rate in Group 1 was 41.69%, in Group 2 it was 27.0%, in Group 3 it was 6.66%, and in Group 4 it was 11.2%. The necrosis rate in Group 1 was found to be statistically significantly higher than other groups (p < .01), the necrosis rate in Group 2 was found to be statistically significant higher than Groups 3 and 4 (p < .01), and the necrosis rate in Group 4 was found to be statistically significant higher than Group 3 (p < .01). CONCLUSION: Cilostazol treatment seemed to increase the viability of TRAM flap, especially when administered as adjuvant therapy. PMID- 27707080 TI - National service framework a GNP response.

PMID- 27707082 TI - Activities of daily living and transition to community living for adults with intellectual disabilities. AB - BACKGROUND: As adults with intellectual disability (ID) in Ireland move to the community from residential settings, the changed environment is intended to increase opportunities for occupational engagement, autonomy and social relationships. It is important to consider how increased resources and opportunities available within the community can be optimized to promote engagement and quality of life. AIMS: This paper investigates if and how ADL and IADL performance of people ageing with ID is related to place of residence. METHODS: ADL and IADL performance of adults with ID in Ireland across different living situations was analyzed using descriptive and bivariate analysis of data collected from the Intellectual Disability Supplement to the Irish Longitudinal Study on Ageing (IDS TILDA). RESULTS: Greater ability to perform ADL and IADL was noted in those living in independent or community group home settings when compared to traditional residential settings. Place of residence was strongly related to ADL and IADL performance. CONCLUSION AND SIGNIFICANCE: Given that people with ID will likely require physical and social supports to complete ADL and IADL when transitioning to community living from residential settings, an occupational justice perspective can inform occupational therapists working with people with ID, facilitating successful transitions to community living. PMID- 27707083 TI - Potentiality of syringetin for preferential radiosensitization to cancer cells. AB - PURPOSE: To examine the enhancing effects of syringetin on the radiosensitivity of normal and cancer cells, and the related mechanism. MATERIALS AND METHODS: We used normal human lung and mouse fibroblasts as well as human lung and mouse cancer cells derived from the above normal fibroblasts. Cell radiosensitivity was measured using a colony formation assay. Apoptosis was analyzed with DAPI staining and Western blots. DNA lesions were analyzed with gammaH2AX immunofluorescent staining. RESULTS: The colony formation assay showed that syringetin enhanced radiosensitivity more effectively in cancer cells (H1299 and C3H/MCA clone 15) compared with normal cells (HFL-III and C3H/10T1/2). The radiosensitizing effect of syringetin was observed in mutated p53 and wild-type p53-transfected H1299 cells regardless of p53 status. Apoptosis was more frequently observed in X-ray-irradiated H1299 cells combined with syringetin compared with X-ray-only-treated cells. Enhanced apoptosis by syringetin was not observed in HFL-III cells. Western blot analysis showed that X-ray-induced Caspase-3 activation was enhanced by syringetin in H1299 cells. The number of X ray-induced DNA double-strand breaks (DSB) measured by quantitative analysis of gammaH2AX foci was the same for H1299 cells treated with X-rays with or without syringetin. CONCLUSIONS: This study supports the hypothesis that syringetin enhances radiosensitivity more effectively in cancer cells than in normal cells through enhancement of the Caspase-3-mediated apoptosis pathway. Syringetin could be useful in the development of novel efficacious radiosensitizers. PMID- 27707086 TI - A betrayal of trust?

AB - Sleep disturbances commonly occur after traumatic brain injury (TBI) and may predispose patients to epileptic seizures. We hypothesized that unprovoked seizure occurrence post-TBI depends on the sleep-wake cycle, and that the electrographic characteristics of a given sleep stage provide biomarkers for post traumatic epilepsy (PTE). We show, in a rat lateral fluid percussion model, that 92% of spontaneous generalized seizures occur during the transition from stage III to rapid eye movement sleep. Moreover, a reduction in spindle duration and dominant frequency during the transition stage present as specific and sensitive noninvasive biomarkers for experimentally induced PTE with generalized electrographic seizures.

PMID- 27707099 TI - Medication adherence as a learning process: insights from cognitive psychology. AB - Non-adherence to medications is one of the largest contributors to sub-optimal health outcomes. Many theories of adherence include a 'value-expectancy' component in which a patient decides to take a medication partly based on expectations about whether it is effective, necessary, and tolerable. We propose reconceptualising this common theme as a kind of 'causal learning' - the patient learns whether a medication is effective, necessary, and tolerable, from experience with the medication. We apply cognitive psychology theories of how people learn cause-effect relations to elaborate this causal-learning challenge. First, expectations and impressions about a medication and beliefs about how a medication works, such as delay of onset, can shape a patient's perceived experience with the medication. Second, beliefs about medications propagate both 'top-down' and 'bottom-up', from experiences with specific medications to general beliefs about medications and vice versa. Third, non-adherence can interfere with learning about a medication, because beliefs, adherence, and experience with a medication are connected in a cyclic learning problem. We propose that by conceptualising non-adherence as a causal-learning process, clinicians can more effectively address a patient's misconceptions and biases, helping the patient develop more accurate impressions of the medication.

PMID- 27707107 TI - ? AB - Attention is increasingly being paid to the issue of violence and aggression against clinical staff. This study carried out in England employed an anonymous semistructured questionnaire sent to all nursing, therapy and psychology staff in a unit providing services for older people and people who had suffered a head injury. The definition of violence was an open one, asking respondents about incidents 'in which violence or aggression was a feature and in which you were a victim'. The response rate to the questionnaire was 34 per cent. Fiftyone per cent of the staff had experienced an incident of violence or aggression in the previous year. Two respondents reported patient violence or aggression which they felt had been provoked by staff. Of those who reported consequences from the incident, psychological effects were the most common. Even though the trust in which the study was carried out had a staff support department, two thirds of the sample said they were unaware of its existence. The authors conclude by suggesting that a national survey of staff support initiatives may be worthwhile.

PMID- 27707109 TI - Efficacy of Particulate Amniotic Membrane and Umbilical Cord Tissues in Attenuating Cartilage Destruction in an Osteoarthritis Model. AB - Osteoarthritis (OA) is a progressive degenerative joint disease, and to date, no disease-modifying OA drug exists. Amniotic membrane and umbilical cord products have been used clinically in several diseases due to their anti-inflammatory and antiscarring properties. In the present study, we sought to evaluate whether a particulate amniotic membrane and umbilical cord (AM/UC) matrix could aid in attenuating disease progression. Lewis rats underwent medial meniscus transection (MMT) to induce OA. Two weeks after surgery, animals received intra-articular injections (50 MUL) of either 50 or 100 MUg/MUL particulate AM/UC or saline control and were subsequently euthanized 1 or 4 weeks later. Cartilage degeneration was assessed using both histological scoring methods and equilibrium partitioning of an ionic contrast agent-microcomputed tomography (EPIC-MUCT). EPIC-MUCT analysis demonstrated that overall cartilage destruction was attenuated, with a significant increase in both cartilage thickness and volume as well as a significant decrease in total lesion area in animals injected with either dose of particulate AM/UC at 1 week, but only a high dose at 4 weeks postinjection. Osteoarthritis Research Society International (OARSI) histology scores of tibial sections corroborated EPIC-MUCT results. Overall joint destruction was attenuated in animals injected with either dose of AM/UC tissue compared with saline-injected control animals at 1 week postinjection. Only high dose AM/UC-injected animals continued to show less overall joint destruction by 4 weeks postinjection. Intra-articular injection of particulate AM/UC tissue attenuates cartilage degradation in a rat MMT model of OA, suggesting that it may be able to slow joint destruction in patients with OA.

AB - Purpose The Edmonton Zone, one of five Zones in Alberta Health Services (the health system in the province of Alberta, Canada), established a quality management framework (QMF) as a means to improve the delivery of high quality health care in the spring of 2014. The purpose of this research study was to understand the factors that facilitated or hindered the implementation of a quality improvement (QI) initiative for hand hygiene led by a newly formed frontline unit quality council (UQC), a part of the QMF, based out of the pediatric intensive care unit (PICU) at the Stollery Children's Hospital in the Edmonton Zone. This research will provide an understanding of the newly established QMF in the Edmonton Zone and the factors needed to foster the ongoing development of frontline UQC that do improvement work as part of their daily routine. Design/methodology/approach Using a qualitative case study research design data were collected using semi-structured open-ended interviews with six key stakeholders (one registered nurse, one physician, one patient case manager, medical director for QI, clinical QI consultant and director of clinical QI) involved in UQC at the PICU. Findings Individual, unit and organizational level factors were identified as influencing the function of the UQC. Leadership and work culture were the key facilitating factors to success and lack of QI training and personnel/dedicated time were perceived barriers to completing the QI initiative. Originality/value The findings from this research illustrate that frontline UQC are able to impact positive sustained change early in their establishment as part of a larger QMF. It is important, however, for the system to foster ongoing development of capacity and capability of these frontline UQC to ensure sustained success of the larger systems change. PMID- 27707148 TI - A randomised study of leadership interventions for healthcare managers. AB - Purpose The purpose of this paper was to assess two different leader development interventions by comparing their effects on leadership behaviour and evaluating their combined impact after two years, from the viewpoints of both the participating managers and external raters. Design/methodology/approach The study was a longitudinal randomised controlled trial with a cross-over design. Health care managers ( n = 177) were first randomised to either of two 10-month interventions and a year later were switched to the other intervention. Leadership behaviour was rated at pre-test and 12 and 24 months by participating managers and their superiors, colleagues and subordinates using a 360-degree instrument. Analysis of variance and multilevel regression analysis was performed. Findings No difference in effect on leadership behaviour was found between the two interventions. The evaluation of the combined effect of the interventions on leadership behaviour showed inconsistent (i.e. both increased and decreased) ratings by the various rater sources. Practical implications This study provides some evidence that participation in leadership development programmes can improve managers' leadership behaviours, but the results also highlight the interpretive challenges connected with using a 360-degree instrument to evaluate such development. Originality/value The longitudinal randomised controlled design and the large sample comprising both managers and external raters make this study unusually rigorous in the field of leadership development evaluations. PMID- 27707149 TI - The implementation of problem-based learning in health service management training programs. AB - Purpose Strengthening management capacity within the health care sector could have a significant impact on population health. However, many training programs in this area are still delivered using a classic lecture-based approach. The purpose of this paper is to evaluate and better understand the feasibility of using a problem-based learning (PBL) approach in health services management training programs. Design/methodology/approach A PBL teaching approach (based on the Maastricht University model) was tested with second-year postgraduate students from the Master in Public Health Management program at the Lithuanian University of Health Sciences. Students' opinions about PBL were investigated using a questionnaire with eight open-ended questions. Thematic content analysis was chosen to reflect the search for patterns across the data. Findings Respondents stated that the main advantage of PBL was that it was a more interesting and effective way of learning: "It is easier to remember, when you study by yourself and discuss with all peers". In addition, it was mentioned that PBL initiated a rapid exchange of ideas and sharing of personal experience. Students stressed that PBL was a good tool for developing other skills as well, such as "public speaking, communication, logic thinking". All students recommended delivering all other courses in the health services management program using PBL methodologies. Originality/value Findings from our study suggest that PBL may be an effective approach to teaching health services management. Potential problems in implementation are noted. PMID- 27707150 TI - The need for leadership training in long-term care settings. AB - Purpose Globally, in 1980, approximately 5.8 per cent of the world population was 65 years old and older. By 2050, this number will more than triple to 16 per cent. From a leadership perspective, there is at least one challenge (among many others challenges) to consider. This paper (viewpoint) aims to provide support for the growing need for academically prepared managers. Design/methodology/approach This paper is a viewpoint which presents several characteristics of the long-term care (LTC) field that support the need for academically trained leaders. Findings LTC leaders in all countries must be sufficiently versed in numerous management areas to provide leadership when called on by those assigned to their care. Given local area variations in population needs present across all countries, it may be unwise to advocate for national, countrywide standardization of requirements. Yet, older adults accessing LTC services should expect a minimum level of knowledge from all of their providers - not just those who provide direct, hands-on care. However, similar to those who provide direct care, leaders should receive competency-based education with specific attention to effective communication skills, team-based approaches to care delivery, information technologies and population health. Originality/value Although much of the extant literature focuses on the delivery of care to older persons, there is a dearth of literature addressing the role of LTC leaders in light of global aging. Establishing a minimum level of academic training and increasing transparency focused on the positive experiences of elders residing in LTC facilities should help dispel the notion that placement in an LTC facility reflects filial failure. PMID- 27707151 TI - Addressing current and future challenges for the NHS: the role of good leadership. AB - Purpose This paper aims to describe and analyse some of the ways in which good leadership can enable those working within the National Health Service (NHS) to weather the changes and difficulties likely to arise in the coming years, and takes the format of an essay written by the prize-winner of the Faculty of Medical Leadership and Management's Student Prize. The Faculty of Medical Leadership and Management ran its inaugural Student Prize in 2015-2016, which aimed at medical students with an interest in medical leadership. In running the Prize, the Faculty hoped to foster an enthusiasm for and understanding of the importance of leadership in medicine. Design/methodology/approach The Faculty asked entrants to discuss the role of good leadership in addressing the current and future challenges faced by the NHS, making reference to the Leadership and Management Standards for Medical Professionals published by the Faculty in 2015. These standards were intended to help guide current and future leaders and were grouped into three categories, namely, self, team and corporate responsibility. Findings This paper highlights the political nature of health care in the UK and the increasing impetus on medical professionals to navigate debates on austerity measures and health-care costs, particularly given the projected deficit in NHS funding. It stresses the importance of building organisational cultures prizing transparency to prevent future breaches in standards of care and the value of patient-centred approaches in improving satisfaction for both patients and staff. Identification of opportunities for collaboration and partnership is emphasised as crucial to assuage the burden that lack of appropriate social care places on clinical services. Originality/value This paper offers a novel perspective - that of a medical student - on the complex issues faced by the NHS over the coming years and utilises a well-regarded set of standards in conceptualising the role that health professionals have to play in leading the NHS.

AB - Purpose This paper aims to contribute to the debate concerning total quality management (TQM)-Lean strategy in public healthcare by analyzing the deployment path for implementation, the possible benefits that can be achieved and the encountered pitfalls. Design/methodology/approach Three case studies are drawn from three large Italian hospitals with more than 500 beds each and structured with many departments. The hospitals are located in Tuscany, Italy. These three hospitals have embraced TQM and Lean, starting from strategic objectives and their deployment. At the same time, they have also implemented many TQM-Lean tools. The case studies are based on interviews held with four managers in each of these three public hospitals. Findings Results from the interviews show that there is a specific deployment path for TQM-Lean implementation. The hospitals have also achieved benefits linked to patient satisfaction and improved organizational performances. Problems related to organizational and cultural issues, such as senior managers' commitment, staff management, manufacturing culture and tools adaptation, could affect the benefits. Research limitations/implications The research has been carried out in just three Italian public hospitals. Hence, similar investigations could be managed in other countries. Researchers could also use a larger sample and investigate these issues by means of quantitative inquiry. Practical implications Practitioners could try to apply the deployment path revealed by these case studies in other public and private hospitals. Originality/value The results of this research show that there is a specific, new deployment path for implementing TQM-Lean strategy in some public hospitals. PMID- 27707156 TI - Nurse nurse.

Participants completed the Delis-Kaplan Executive Function System. Individuals with TLE performed worse than the DEP group on many tests of executive functions. Among the TLE participants, those with depression demonstrated poorer executive functioning. These findings support the notion that depression may further contribute to executive difficulties in individuals with TLE. Depression treatment in this population could lead to improvements in cognition. PMID- 27707195 TI - Effect of High-Frequency Transcranial Magnetic Stimulation on Craving in Substance Use Disorder: A Meta-Analysis. AB - Repetitive transcranial magnetic stimulation (rTMS), a noninvasive, neuromodulatory tool, has been used to reduce craving in different substance use disorders. There are some studies that have reported conflicting and inconclusive results; therefore, this meta-analysis was conducted to evaluate the effect of high-frequency rTMS on craving in substance use disorder and to investigate the reasons behind the inconsistency across the studies. The authors searched clinical trials from MEDLINE, Cochrane databases, and International Clinical Trials Registry Platform. The PRISMA guidelines, as well as recommended meta analysis practices, were followed in the selection process, analysis, and reporting of the findings. The effect estimate used was the standardized mean difference (Hedge's g), and heterogeneity across the considered studies was explored using subgroup analyses. The quality assessment was done using the Cochrane risk of bias tool, and sensitivity analysis was performed to check the influences on effect size by statistical models. After screening and assessment of eligibility, finally 10 studies were included for meta-analysis, which includes six studies on alcohol and four studies on nicotine use disorder. The random-model analysis revealed a pooled effect size of 0.75 (95% CI=0.29 to 1.21, p=0.001), whereas the fixed-model analysis showed a large effect size of 0.87 (95% CI=0.63 to 1.12, p<0.00001). Subgroup analysis for alcohol use disorder showed an effect size of -0.06 (95% CI=-0.89 to 0.77, p=0.88). In the case of nicotine use disorder, random-model analysis revealed an effect size of 1.00 (95% CI=0.48 to 1.55, p=0.0001), whereas fixed-model analysis also showed a large effect size of 0.96 (95% CI=0.71 to 1.22). The present meta-analysis identified a beneficial effect of high-frequency rTMS on craving associated with nicotine use disorder but not alcohol use disorder.

AB - This literature review considers different ideas about ageing. It explores how growing older is conceptualised, including polarised views that see old age either as inevitable decline with efforts made to identify ways of coping, or as an enemy to be fought, with submission to its effects viewed as defeat and failure. Reviewing an extensive and diverse range of literature, it suggests that a new concept of older age may be needed and highlights areas for further research. PMID- 27707233 TI - Events. AB - Our roundup of what's on. PMID- 27707234 TI - Competition watchdog will examine care homes sector. AB - The Office of Fair Trading (OFT) is to investigate the care homes sector and examine ways in which older people make choices about a care home and how these affect competition in the market. The move follows a 'super-complaint' by the Consumers' Association which highlighted concerns about the care home sector in England. But groups representing care homes have said the OFT inquiry will not go far enough because it will not investigate fees paid by local authorities. PMID- 27707235 TI - Use of physical restraints with cognitively impaired nursing home residents. AB - The issue of whether restraints should be used in nursing home settings in order to reduce the number of injuries resulting from falls remains controversial on a world-wide basis. In this Dutch study, the care of 265 residents was examined. It was found that restraints were used with 49 per cent of residents, the most frequently encountered being bed rails, belts, and 'geriatric' chairs with a table attached. The most common reason given by nursing staff for the use of restraints was the prevention of falls, followed by a need to control restlessness, and to allow the safe use of medical devices. A novel aspect of this study was that four members of staff volunteered to experience the use of restraints for themselves during a 24- hour period. They reported a complete absence of privacy and freedom of movement, together with physical discomfort. The authors conclude that there is a need to review the use of such restraints in all their aspects. PMID- 27707236 TI - Older patients with chronic heart failure within Swedish community health care: a record review of nursing assessments and interventions. AB - Nursing records can provide a valuable source of information for the researcher. In this study, community nursing records for two periods of two years were reviewed retrospectively in order to locate and analyse statements relating to the monitoring of patients with chronic heart failure. The older people being studied were drawn from nursing homes, specialist housing for older people, and those living in their own homes. The total number of records included in the sample was 161, and appropriate instruments were used to collect the data in a systematic manner. However, the records were found to be largely ordered in a chronological sequence, and written in a narrative form, but without a shared format or structure. Drug administration was the most commonly recorded nursing intervention, while only 12 per cent of records indicated that patients were being weighed, and 3 per cent recorded health promotion activities.

The main issue being experienced by the participants was unresolved grief following the death of a partner. By the end of the 12-week process, six of the seven group members were reporting an improvement which was sufficient to enable them to be discharged from treatment. PMID- 27707238 TI - Factors associated with variations in older people's use of community-based continence services. AB - The fact that a service is available provides no guarantee that those who would benefit from it will actually use it, and that is especially the case for those with stigmatising conditions such as urinary incontinence. This study involved a cross-sectional postal survey of patients aged over 65 who were registered with four general practices in a socially deprived urban area (n=1,376). The overall response rate was 66 per cent. The proportion of the sample reporting urinary leakage was 39 per cent, although only 15 per cent had accessed relevant services. The authors suggest that contacts with the primary care team should be used to explore the issue of urinary incontinence through the use of a validated assessment instrument.

PMID- 27707245 TI - RENEB - Running the European Network of biological dosimetry and physical retrospective dosimetry. AB - PURPOSE: A European network was initiated in 2012 by 23 partners from 16 European countries with the aim to significantly increase individualized dose reconstruction in case of large-scale radiological emergency scenarios. RESULTS: The network was built on three complementary pillars: (1) an operational basis with seven biological and physical dosimetric assays in ready-to-use mode, (2) a basis for education, training and quality assurance, and (3) a basis for further network development regarding new techniques and members. Techniques for individual dose estimation based on biological samples and/or inert personalized devices as mobile phones or smart phones were optimized to support rapid categorization of many potential victims according to the received dose to the blood or personal devices. Communication and cross-border collaboration were also standardized. To assure long-term sustainability of the network, cooperation with national and international emergency preparedness organizations was initiated and links to radiation protection and research platforms have been developed. A legal framework, based on a Memorandum of Understanding, was established and signed by 27 organizations by the end of 2015. CONCLUSIONS: RENEB is a European Network of biological and physical-retrospective dosimetry, with the capacity and capability to perform large-scale rapid individualized dose estimation. Specialized to handle large numbers of samples, RENEB is able to contribute to radiological emergency preparedness and wider large-scale research projects.

It is north American in origin and, while it will be invaluable for teachers of statistics to nurses and other healthcare professionals, it is probably not suitable for many preor post-registration students in health in the UK. The material is quite advanced and, while well illustrated, exemplified and with numerous examples for students, it takes a fairly mathematical approach in places. Nevertheless, the book has much to commend it, including a CD-ROM package containing tutorials, a statistical package, solutions based on the exercises in the text and case studies. PMID- 27707295 TI - Social research Sotirios Sarantakos Social research Palgrave Macmillan 500 L19.99 1403943206 1403943206 [Formula: see text]. AB - I found Sarantakos's book to be a clear and straightforward guide to social research methods. The book is aimed at undergraduate level, and I am sure will appeal to students from a range of disciplines. The structure of the book reflects the different stages of the research process and as such it is easy to locate all the required sections. It introduces qualitative and quantitative approaches in a balanced way and includes sufficient detail of the philosophical roots of each of these research traditions. It was good to find simple and easy to follow accounts of the complex underpinning of a number of research approach that are popular in nursing research. Included are topics such as interpretivism, symbolic interactionism and phenomenology as well the more usually found hallmarks of positivistic-type research. While feminism and feministic research in nursing is an important subject area I did wonder if the amount of attention they received were perhaps a little unbalanced when related to the other subject areas covered. There are, however, useful sections on data collection and analysis. I found, for example, the section on grounded theory approaches to data analysis particularly good. PMID- 27707296 TI - Making the most of opportunities.. AB - When asked to contribute to the Making My Mark series, my immediate response was to agree. Once I had done so, I began to wonder what sort of mark I have actually made. For inspiration, I looked back at previous papers in the series, to establish where, in the grand scheme of things, my contribution to nursing and healthcare research might lie. I found papers written by both highly experienced and internationally known researchers and by those just starting out on a research career. My position lies somewhere between these two, and if I can borrow a term coined by a research collaborator, Dr Jeremy Segrott, University of Wales Swansea School of Health Care, I would describe myself as a 'midiphyte' (someone with postgraduate training and hands-on research experience, but who has yet to become a totally independent and self-supporting researcher). To borrow a term from another colleague, I also see myself as something of a 'butterfly'; someone who is still defining a clear research niche and who has engaged with a number of different projects as the need or opportunity has arisen. PMID- 27707297 TI - Qualitative methods for health research J Judith Green Qualitative methods for health research and Nicki Thorogood Sage 280 L19.99 076194771X [Formula: see text]. AB - When I first looked at this book I wondered if there was room for yet another title on qualitative research in health. Indeed, the authors point out that there are already many excellent introductory textbooks available on this topic. However they have identified similar gaps in the literature as I have in working particularly with postgraduate students and neophyte researchers. In my view, their book has largely been successful in filling the gaps. PMID- 27707298 TI - Research can be challenging, but it is always rewarding. AB - Research can be a scary business. For new researchers it may appear as a minefield to be entered as a necessity and negotiated with caution. For those of us who have some experience of research, there is the knowledge that each project brings with it a different set of challenges to be completed in what appears to be an ever-changing landscape. So, irrespective of whether you are a highly experienced nurse researcher, a novice or (like many of us) somewhere in between, the process of conducting research brings new opportunities and challenges. This constantly evolving landscape governs and influences many aspects of the research process from formulation of initial ideas, through ethical considerations, data collection, analysis and completion. To a great extent, success is dependent on a mixture of luck, judgement and determination. PMID- 27707299 TI - Ethical footprints: finding a way through the research process. AB - In common with other facets of modern life in the 21st century, the nursing research context is dynamic and constantly changing. It is not only the neophyte researcher who is required to keep abreast of current legislative regulations and frameworks that guide the conduct of research. More experienced researchers also require knowledge and understanding of contemporary research ethics and governance frameworks in order to conduct research and guide students. In designing, operationalising, reporting and disseminating research we ought to aspire to leave 'ethical footprints'. By this I mean that those researchers who follow in our research journey may tread in our foot- prints with the knowledge that the conduct of our research has been ethical.

AB - When this book landed on my desk I wasn't sure of its value. However, within a few days I had already found it extremely useful. The book will be a valuable resource for researchers at all stages of their careers. It acts as a starting point for those seeking information about a vast array of research-related topics. For example, if you want to know something about triangulation, a section that provides a definition is followed by a list of references and a few lines describing the content and usefulness of each reference. Should you be looking for information about a specific approach, an extensive list of references is provided about a broad range of methodologies. PMID- 27707301 TI - Triangulation as a method for contemporary nursing research. AB - The complex nature of phenomena investigated by nurses demands the use of a multifaceted approach to develop nursing knowledge. Triangulation offers a rigorous methodological framework by which to achieve this aim. The authors describe the historical and philosophical underpinnings of triangulation and outline considerations in relation to applying it in contemporary nursing research.

PMID- 27707303 TI - Patient confidentiality, clinical data and NHS research - a researcher's guide. AB - More stringent research governance in the NHS has led to an increased focus on the importance of patient confidentiality. But relatively low levels of knowledge of the Data Protection Act and common law duty of confidentiality among some researchers and research managers cause difficulties in getting research projects off the ground. The authors outline the main issues surrounding research, data protection and patient confidentiality, and provide guidance for researchers, clinicians and managers on how to conduct research appropriately.

AB - It is noticeable that the attention of clinical researchers worldwide is increasingly being focused upon the effects of heart failure, which in the past may not have had the attention given to other conditions. Despite a range of innovative treatments, morbidity and mortality rates in heart failure remain high. In this American study, the psychometric properties of three quality of life scales were compared. These were the Chronic Heart Failure Questionnaire (CHFQ), the Minnesota Living with Heart Failure Questionnaire (LHFQ), and the General Health Survey Short-form12 (SF-12). A convenience sample of 211 patients with heart failure completed baseline questionnaires via telephone interviews. Follow-up interviews were conducted at four, eight and 26 weeks. A total of 165 patients (78 per cent) completed the study, while 11 patients (5 per cent) died during the course of the research project. Overall, the results indicated that patients had a lowto-moderate health-related quality of life. PMID- 27707317 TI - An exploration of the contribution of the community nurse to rehabilitation. AB - In all the recent discussion of the need to improve the co-ordination and delivery of rehabilitation services for older people, community nurses often feel, with some justice, that their potential contribution has been overlooked. So this paper is timely in its focus on an area of nursing practice that is ripe for development. The researchers used a grounded theory approach to the analysis of data generated by focus group discussions and individual interviews with district nurses. The results indicated that community nurses described their practice as 'holistic' in combining both health and social aspects. They were involved in making assessments, referrals, teaching and educating, and providing technical care. Despite this major contribution, many of the nurses felt that their role in rehabilitation was not clearly defined or accorded sufficient recognition by other service providers.

In this thought-provoking paper, 32 subjects with mild to moderate dementia were recruited from attenders at two day hospitals. Subjects and their carers completed range of assessment tools, and then took part in semi-structured interviews. Themes identified in the interviews included frustration, distress and anger, discontent, unconcern, a normalizing response, worry and anxiety, defensiveness, explicit denial, and priority given to other problems. The researchers conclude that insight is a complex, multi-dimensional and value-laden concept. PMID- 27707333 TI - Home owners' fury over CRB checks.

AB - There is increasing recognition that for many older people, a fall causing a hip fracture can start a process of increasing dependency and reduced quality of life. However, this is not an inevitable outcome and researchers are keen to identify factors which may influence prognosis. In this American study, data were obtained from 23 women (age range 65 - 95 years) who had sustained a hip fracture within the previous four years. A range of instruments were completed by a research nurse, including measures of independence in activities of daily living, and osteoporosis risk. Eighteen of the women were able to obtain maximum scores for independence in living activities after the fracture was treated. The results provided the positive message that older women who were living independently before their fall can expect a high level of recovery from this traumatic event.

AB - This small-scale study set out to test the hypothesis that there was an association between skin surface temperature and perceived pain in osteoarthritis. If such an association could be demonstrated in cognitively intact older people, the authors argued that it could form a useful aid to assessment for those who were cognitively impaired. Unfortunately, no such significant relationship was found. The authors suggest that environmental influences may outweigh the effects of inflammation of the knee joint in influencing skin temperature. They conclude by suggesting that the study should be repeated with a larger sample who had radiographic evidence to establish the extent of their osteoarthritis. PMID- 27707339 TI - Website watch.

PMID- 27707353 TI - Glutathione-dependent micelles based on carboxymethyl chitosan for delivery of doxorubicin. AB - Novel glutathione (GSH)-dependent micelles based on carboxymethyl chitosan (CMCS) were developed for triggered intracellular release of doxorubicin (DOX). DOX-33' Dithiobis (N-hydroxysuccinimidyl propionate)-CMCS (DOX-DSP-CMCS) prodrugs were synthesized. DOX was attached to the amino group on CMCS via disulfide bonds and drug-loaded micelles were formed by self-assembly. The micelles formed core-shell structure with CMCS and DOX as the shell and core, respectively, in aqueous media. The structure of the prodrugs was confirmed by IR and proton nuclear magnetic resonance (1H NMR) spectroscopy. The drug-loading capacity determined by UV spectrophotometry was 4.96% and the critical micelle concentration of polymer prodrugs determined by pyrene fluorescence was 0.089 mg/mL. Micelles were spherical and the mean size of the nanoparticles was 174 nm, with a narrow polydispersity index of 0.106. Moreover, in vitro drug release experiments showed that the micelles were highly GSH-sensitive owing to the reductively degradable disulfide bonds. Cell counting kit (CCK-8) assays revealed that DOX-DSP-CMCS micelles exhibited effective cytotoxicity against HeLa cells. Moreover, confocal laser scanning microscopy (CLSM) demonstrated that DOX-DSP-CMCS micelles could efficiently deliver and release DOX in the cancer cells. In conclusion, the DOX DSP-CMCS nanosystem is a promising drug delivery vehicle for cancer therapy. PMID- 27707354 TI - Cognitive screening in Multiple Sclerosis: the Five-Point Test as a substitute for the PASAT in measuring executive function. AB - OBJECTIVE: The Paced Auditory Serial Addition Test (PASAT) is frequently employed to measure executive functions in patients with Multiple Sclerosis (MS). In the past, the PASAT has often been criticized because of its stressful and demanding requirements. Continuous utilization might also reduce its validity. The Five Point Test (FPT) by Regard, Strauss, and Knapp ((1982) Children's production on verbal and non-verbal fluency tasks. Perceptual and Motor Skills, 55, 839-844.) is a short test of figural fluency which might serve as a substitute. METHOD: 116 patients diagnosed with MS were tested with a short version of the Brief Repeatable Battery (BRB) by Rao and the Cognitive Function Study Group of the National Multiple Sclerosis Society including the PASAT, as well as the FPT. A factor analysis was computed and the frequency of cognitive impairment was calculated for both the original short version of the BRB and the alternative version (involving the FPT). RESULTS: In the factor analysis, PASAT and FPT loaded highest on the same factor (two factors were extracted). The estimation of the frequency of cognitive impairment showed that replacing the PASAT with the FPT did not considerably alter the proportion of patients identified as cognitively impaired. CONCLUSIONS: The FPT proved to be a viable alternative to the PASAT in this study. It may be recommended as a possible replacement in neuropsychological screening of MS-patients with the advantage of avoiding the indicated limitations of the PASAT.

PMID- 27707355 TI - Validation and application of a liquid chromatography-tandem mass spectrometry based method for the assessment of the co-occurrence of mycotoxins in maize silages from dairy farms in NW Spain. AB - The first objective of this study was the validation of an efficient multi analyte method for the simultaneous detection and quantification of mycotoxins in maize silage, by reverse-phase liquid chromatography coupled with electrospray ionisation triple quadrupole mass spectrometry (LC-HESI-MS/MS). A simple liquid/solid extraction was performed either with clean-up on Mycospin 400 columns or without any clean-up. Almost all the target mycotoxins showed highly suppressed signals in the presence of a matrix, emphasising the need to quantitate mycotoxins by means of matrix-matched calibrations. An alternative validation method based on ISO 11843 and on a single factor balanced design was implemented. The achieved average recoveries from spiked samples at three levels ranged from 60% to 122% with relative standard deviations (rsd) below 11%. Limits of Detection (LODs) and Limits of Quantification (LOQs) were between 0.02-17.1 ug kg-1 and 0.06-57 ug kg-1. The calculated repeatability and within-lab reproducibility ranged from 5.2 to 23.2% and from 7.2 to 23.9%, respectively. Finally, the decision limit and detection capacity, CCalpha and CCbeta, were calculated for all mycotoxins having regulated/recommended contents in feed. The validated method was applied to 148 samples collected over two years in 19 dairy farms from Galicia (NW Spain). Of the analysed samples, 62% contained at least one mycotoxin. Zearalenone (ZEA), deoxynivalenol (DON), fumonisins B1 and B2, roquefortine C, alpha-zearalenol, beta-zearalenol, enniatins B and B1, andrastin A, marcfortine A, verruculogen and mycophenolic acid were quantified, the highest average detection frequency being for enniatin B (51%). DON, mycophenolic acid and ZEA plus metabolites (alpha-zearalenol, beta-zearalenol) were the most abundant mycotoxins.

PMID- 27707365 TI - A survey on the potential relationships between TMD, possible sleep bruxism, unilateral chewing, and occlusal factors in Turkish university students. AB - OBJECTIVE: To evaluate whether there is a relationship between possible sleep bruxism (PSB), temporomandibular disorders (TMD), unilateral chewing (UC), and occlusal factors in university students recruited from Cumhuriyet University in Turkey. METHODS: For this cross-sectional survey, 519 (223 males, mean age 21.57 +/- 2.3 years, 296 females, mean age 21.02 +/- 2 years) university students who admitted to the Department of Oral and Maxillofacial Radiology of the Faculty of Dentistry, Cumhuriyet University for dental care between 2012 and 2014 were selected randomly. Students were asked to complete a questionnaire form including questions about TMD, PSB and UC. Presence and direction of malocclusion were recorded during clinical examination. Chi-square test was used for statistical analysis. RESULTS: It was found that 96.6% of the students with PSB had TMD (p < 0.05). The prevalence of severe TMD was high among students with PSB. There was a significant association between UC, PSB and TMD (p < 0.05). No statistically significant association was found between occlusal factors and PSB and TMD (p > 0.05). CONCLUSION: Sleep bruxism, which heavily depends on self-report, is significantly associated with TMD. Unilateral chewing seems to be a common factor for development of SB and TMD. However, further studies are needed to corroborate this finding. Additionally, this study supports the hypothesis that occlusal factors are not related to self-reported sleep bruxism. PMID- 27707369 TI - A multi-stage approach to the coding of data from open-ended questions. AB - One of the criticisms of qualitative research is that the processes and procedures of data analysis tire often not made explicit ( 1 ). This criticism is particularly pertinent to the analysis of open-ended questions. This paper outlines an approach to analysing open-ended questions using content analysis, making explicit the processes and procedures involved. The paper will also describe how the challenge of ensuring rigour and maintaining the diversity and subtlety of responses, which can easily be lost when attempting to quantify qualitative data, can be overcome. PMID- 27707370 TI - Writing and submitting abstracts for conference presentation. AB - Over the last 25 years it has frequently been said or written that nursing must be a research-based profession and there is now considerable pressure on staff in the NHS to achieve research-based practice. But this means that nurses must first know about relevant research findings. Hunt's comment ( 1 ) that nurses do not know about research findings has been quoted frequently, much nursing research is not published ( 2 ), and at least one study indicated that in the 1990s only a minority of nurses read journals regularly ( 3 ). It is possible that even those who do read nursing journals may not read research articles, judging by the journals cited by respondents in the study and their negative comments about reading research. PMID- 27707372 TI - The process and importance of systematic reviews. AB - The current emphasis within the NHS on clinical effectiveness involves the need to ensure that practice is based on knowledge derived from research rather than on strongly held tradition or personal experience. However, busy practitioners find it increasingly difficult to keep abreast of all available research. This is hardly surprising when one considers that there are over 20,000 biomedical journals which contain over two million articles each year ( 1 ). These articles vary greatly in quality and often are not well indexed. Practitioners involved in patient care rarely have the time, resources and skills to gather together and critically appraise relevant research in an effort to inform their practice. However, one way of pulling together unmanageable amounts of research is through a systematic review ( 2 ): 'A systematic- review is the process of systematically locating, appraising and synthesising evidence from scientific studies in order to obtain a reliable overview.' PMID- 27707373 TI - Using meta-analysis to summarise evidence within systematic reviews. AB - Systematic review and meta-analysis are two methods, used to summarise scientific evidence in order to inform further research and policy, that are being used with increasing frequency. It is important, therefore, that nurses and other health professionals understand how a systematic review and meta-analysis are carried out, and something of the relationship between the two methods. Systematic review, also known as overview, and meta-analysis can provide concise information for providers, purchasers and patients. However, it is helpful to appreciate when it may, or may not, be appropriate to perform them, as they are often a justification for wide ranging claims made about effectiveness of healthcare interventions. PMID- 27707374 TI - Editorial. AB - Developing an evidence or research-based culture in nursing is a complex issue. Hicks, in her paper 'Nurse researcher: a study of a contradiction in terms? '( 1 ), suggested: 'The qualities attributed to a good nurse are dissonant with those attributed to a good researcher and, in this way, the mutual incompatibility of each role's requirements may serve as an obstacle to the development of research with nursing.' In other words, good nurses do not make good researchers or vice versa. PMID- 27707375 TI - Dissemination and implementation: the wider picture. AB - The current trend towards the adoption of evidence or knowledge- based practice in nursing provides the opportunity to reassess what has historically been referred to as the 'theory-practice gap'. I believe that the current way in which research findings are disseminated is the most important contributing factor to this gap. This paper will examine some of the issues and, where available, the evidence related to the dissemination of research findings in nursing. This paper addresses three components of dissemination. PMID- 27707376 TI - Publishing original research: principles and practice. AB - Experience has taught me that there is definitely a knack to getting your written research published, although, in this the era of 'evidence- based practice', empirical research to substantiate this claim is sadly lacking. Just as there are good practitioners, good teachers and good researchers, there are good writers. However, it is not always the good writers, and definitely not always the good researchers, who manage to ensure their work is published. It is the experienced or canny writers whose work proliferates, those who can turn their hand to many subjects, or mould any set of information into something that is worthy of publication. PMID- 27707377 TI - Is nursing research detrimental to nursing education and practice? AB - This paper expresses some personal concerns regarding the relationship between nursing education and research, and between nursing practice and research. My aim is to challenge, and to encourage in-depth consideration of, the implications of terms such as 'research-based practice', and more particularly, the concept that 'nursing should be a research-based profession'.

AB - It is reported in the Penguin Book of Interviews ( 1 ) that Marlon Brando recalled an interview with Truman Capote as follows: 'The little bastard spent half the night telling me all his problems, I figured the least I could do was tell him a few of mine.' In sharing experiences with his interviewee, Capote had managed to extract information he would otherwise not have gained. PMID- 27707384 TI - Editorial. AB - Brink and Wood have recently defined the inescapable logic of interviewing in nursing research. 'When your objective is to find out what people believe or think', they write, 'the easiest and most effective method is to ask questions directly of the person' ( 1 ). PMID- 27707385 TI - Personal experience of conducting unstructured interviews. AB - I am at present conducting a PhD study into the effects supernumerary status and mentorship on student nurses. The purpose of this article is to share some of my experiences, and suggest some pointers for planning and conducting unstructured interviews. PMID- 27707386 TI - Analysing data using a wordprocessor. AB - The analysis of data obtained from semi-structured and unstructured interviews is an essential part of many qualitative research studies. While a number of research texts offer suggestions as to how such text may be content analysed, few are explicit on this issue ( 1 , 2 ). The aim of this article is to offer a detailed account of one way of content analysing interview transcripts using a wordprocessor. PMID- 27707387 TI - The Strategy for Research in Nursing in England: Initial impactIn May 1993, the Department of Health published The Report of the Taskforce on the Strategy for Research in Nursing, Midwifery and Health Visiting ( 1 ). The Taskforce had been appointed to consider the scope and objectives of research in England and the interfaces with other areas of health services research. Susan Read reports on its progress. AB - Researchers have often been criticised for their lack of responsibility for disseminating or implementing their findings ( 2 - 4 ). People speak of volumes of research gathering dust on forgotten shelves, and research reports being incomprehensible to the ordinary reader. Researchers too have sometimes criticised sponsoring bodies for taking no notice of their recommendations. PMID- 27707389 TI - The structured interview. AB - Structured interviewing is about uniformity, and is inextricably bound with the use of interview schedules. Some guidance on constructing schedules is therefore included in this article. PMID- 27707390 TI - Unstructured and semi-structured interviewing. AB - At first glance, the idea of collecting data through some kind of interviewing can seem an attractively easy one; it is just talking to people, asking questions and recording the answers. The would-be researcher quickly discovers, however, that interviewing can be a complex and daunting undertaking. PMID- 27707388 TI - Analysing data using grounded theory. AB - Grounded theory is a systematic research approach for the collection and analysis of qualitative data. The aim of the grounded theory approach is to generate an explanatory theory from the data being analysed, rather than trying to 'fit' the data into an existing theoretical framework ( 1 , 2 ). PMID- 27707391 TI - Nursing education and the Research Assessment Exercises. AB - Prior to 1989, the funding of British universities was the responsibility of the University Grants Committee (UGC). The UGC's traditional role was to represent the universities to government, and to act as a buffer between the two, the aim being to enable the universities to be independent of central (political) control ( 1 ). PMID- 27707392 TI - Analysing data: alternative methods. AB - It is widely appreciated that research is a practical as well as an intellectual activity. The essence of communicating the research process effectively to others depends largely upon the researcher's ability to convey clearly not only intellectual rigour, but also the stages through which information was collected and interpreted. PMID- 27707394 TI - Varieties of research interviews. AB - Interviewing can claim to be the most widely used method of research. It is therefore no surprise that interviewing takes many forms. The types of interview are usually differentiated by their degree of structure. Structured interviews In 'structured' (or 'standardised') interviews, the wording of questions and their sequence is the same from one interview to another. The piece of paper the interviewer holds is called the 'interview schedule'. PMID- 27707396 TI - Neurological Trauma and Family Functioning.

However, it is an extremely toxic substance to humans upon exposure with severe and detrimental effects that range from visual loss to death. Spinal cord involvement in methanol intoxication is a rare occurrence. FINDINGS: In this article, we are reporting a case of methanol intoxication with extensive spinal cord involvement possibly due to necrosis. A literature review yielded only two cases of spinal cord involvement due to methanol intoxication. Our article is the first to discuss the spinal cord involvement specifically including interesting neuroimaging features. CONCLUSION/CLINICAL RELEVANCE: We recommend performing MRI of the cervicothoracic spine in every methanol intoxication case to exclude both asymptomatic and symptomatic cases of spinal cord involvement.

PMID- 27707403 TI - Leading and co-ordinating a multi-nurse researcher project. AB - Leading and co-ordinating a research project is a complex undertaking involving management of people, processes, budget and material resources. The task is even more complex when there are nine nurse researchers collecting and analysing data in the midst of their practice. In this paper, Theresa Mitchell and Steve Jones describe the experiences of the project lead and co-ordinator responsible for planning and managing such a project in the Oncology Centre in Gloucestershire, UK. Using examples from the project, the authors share some of the potential problems encountered during research activities, and propose strategies and remedies to address them.

However, this publication is worth a closer look. PMID- 27707408 TI - Making the most of time. AB - Undertaking an MPhil or PhD requires the student to develop many different skills, including the all important skill of time management ( Crofts 2002 ). At first glance, the prospect of spending three years (or the part-time equivalent) studying a single topic of interest might seem like an inordinate amount of time; you might even consider it as something of a luxury. However, you are probably familiar with the saying tempus fugit; 'time flies'. In other words, the time which has been set aside for your MPhil or PhD will soon pass. It is important from an early stage that you get to grips with the 'time issue'; that you learn to manage your time effectively. PMID- 27707409 TI - Discourse analysis and social constructionism. AB - Discourse analysis (DA) is underpinned by a social constructionist orientation to knowledge. Social constructionism rests on the philosophical assumptions that multiple versions of the world are legitimate; that texts are open to multiple readings; and that language is non-representational. As social constructionism is relativistic, the status of 'evidence' generated by DA is questionable from more traditional research perspectives. On a common-sense level, people obviously construct meaning in relation to their lives. Thus, DA can help us to examine constructions of meaning in relation to nursing care. Equally, the discourse analyst constructs one possible meaning in relation to a phenomenon that may compete with other versions. Multiplicity does not necessarily entail anarchy, and competing versions prevent authoritarianism and loss of freedom. However, judgements have to be made about competing versions, for example, by assessing the level of 'facticity', or referring to the ethics embedded in the cultural context. In this paper, Bob White discusses DA as a form of qualitative research that offers promise for nursing research. Subsequent papers will examine the methodology and methods of DA and its application to nursing research. PMID- 27707411 TI - Networking works. AB - The importance of networking in bridging the theory-practice gap cannot be underestimated. Developing links with colleagues within your field can offer many opportunities to disseminate good practice and share ideas for the improvement of health care. There are many potential networking opportunities, for example, the RCN is hosting its annual international nursing conference in Belfast, Northern Ireland, UK, from March 8-11 2005. For further information, see: www.man.ac.uk/rcn/research2005/. PMID- 27707410 TI - Application of discourse analysis to nursing inquiry. AB - Discourse analysis (DA) has frequently been misapplied within nursing research, demonstrating a lack of understanding among some nurse researchers of theoretical/ methodological approaches within DA. To date, there are few specific nursing examples illustrating the application of DA, which presents a further obstacle for the new researcher. In this paper, Jim Campbell and Sheila Arnold outline a specific nursing example of DA research and describe the process of applying DA to nursing research via the personal experiences of the authors. Two different ways of 'coming to' a DA approach, will be described, one using a structured framework and the other a personal narrative. PMID- 27707412 TI - Discourse analysis. AB - First, a suggested definition of discourse: at its most general, discourse can be understood as any system of signs, whether spoken, written, or otherwise. I say 'otherwise', because it is possible to 'read' town planning or architecture, for example, as systems that reflect and enact political values and practices. Some use the term a little more specifically; so, for example a phrase such as 'medical discourse' implies an organised and more or less self-conscious system of concepts and language practice which reflects and is supported by an institutional base. Some while ago, Ian Parker set out certain characteristics of discourse and, importantly, questioned any notion of a simple distinction between discourse and 'reality' - something that can be comprehended outside of discourse.

AB - This book emerges at a critical time in developing research to aid understanding of the health needs of minority ethnic groups. The development of key initiatives in the health of minority ethnic groups is hampered by the lack of information about the ways in which issues of 'race', ethnicity and experiences impact on individuals and communities. Researchers working in nursing and health care have begun to research ethnicity and 'race' within a more politicised context which seeks to expose the impact of inequality within a 'race' and ethnicities based framework. PMID- 27707414 TI - Theoretical and methodological approaches in discourse analysis. AB - Discourse analysis (DA) embodies two main approaches: Foucauldian DA and radical social constructionist DA. Both are underpinned by social constructionism to a lesser or greater extent. Social constructionism has contested areas in relation to power, embodiment, and materialism, although Foucauldian DA does focus on the issue of power. Embodiment and materialism may be especially relevant for researchers of nursing where the physical body is prominent. However, the contested nature of social constructionism allows a fusion of theoretical and methodological approaches tailored to a specific research interest. In this paper, Chris Stevenson suggests a frame- work for working out and declaring the DA approach to be taken in relation to a research area, as well as to aid anticipating methodological critique. Method, validity, reliability and scholarship are discussed from within a discourse analytic frame of reference. PMID- 27707415 TI - The evidence for nursing interventions in the Cochrane Database of Systematic Reviews. AB - In this paper, Patriek Mistiaen, Else Poot, Sophie Hickox, and Cordula Wagner describe how they conducted a search of the Cochrane Database of Systematic Reviews in order to explore the evidence for nursing interventions. They identify the number of studies, the number of participants, and the conclusions of systematic reviews concerning nursing interventions. They conclude that the Cochrane Database of Systematic Reviews is a valuable source of evidence about nursing interventions, and can be used as a means of developing a research agenda in the case of inconclusive reviews. PMID- 27707416 TI - Upper trapezius fatigue in carpet weaving: the impact of a repetitive task cycle. AB - INTRODUCTION: Shoulder disorders are one of the most prevalent musculoskeletal disorders among carpet weavers. The most important cause of these disorders is muscle fatigue. The aim of the present study is to investigate the effect of carpet weaving characteristics on upper trapezius (UTr) muscle fatigue during a task cycle. METHOD: In this cross-sectional study, 9 women and 3 men participated. During an 80-min cycle of carpet weaving, a times-series model was applied to assess electromyography amplitude and frequency changes. RESULT: According to the joint analysis of electromyogram spectrum and amplitude method, the participants experienced 0% force decrease, 0.9% recovery, 18% force increase and 72% fatigue in the left UTr. Furthermore, the rates of force decrease, recovery, force increase and fatigue in the right UTr were 18%, 18%, 18% and 45%, respectively. Fatigue in the right and the left UTr was reported to be the dominant state during one carpet weaving task cycle. CONCLUSION: Task cycle appears to have a significant impact on UTr fatigue in participants, and UTr fatigue can be considered a serious risk factor in shoulder musculoskeletal disorders. Hence, further studies should focus on better workstations and work rest periods during various subtasks. PMID- 27707417 TI - [Universal Dutch guideline on 'Venous disease']. AB - - The Dutch guideline on 'Venous disease' comprises four parts: two revised guidelines ('Varicose veins' and 'Venous leg ulcer') and two new guidelines ('Deep venous disease' and 'Compression therapy').- These guidelines were drawn up by a working party made up of representatives from the Dutch Association of Surgeons, the Dutch Society of Vascular Surgery and the Dutch Society of Dermatology and Venereology.- We will discuss the most important parts of the guideline here. PMID- 27707418 TI - The role of chemokines and their receptors during protist parasite infections. AB - Protists are a diverse collection of eukaryotic organisms that account for a significant global infection burden. Often, the immune responses mounted against these parasites cause excessive inflammation and therefore pathology in the host. Elucidating the mechanisms of both protective and harmful immune responses is complex, and often relies of the use of animal models. In any immune response, leucocyte trafficking to the site of infection, or inflammation, is paramount, and this involves the production of chemokines, small chemotactic cytokines of approximately 8-10 kDa in size, which bind to specific chemokine receptors to induce leucocyte movement. Herein, the scientific literature investigating the role of chemokines in the propagation of immune responses against key protist infections will be reviewed, focussing on Plasmodium species, Toxoplasma gondii, Leishmania species and Cryptosporidium species. Interestingly, many studies find that chemokines can in fact, promote parasite survival in the host, by drawing in leucocytes for spread and further replication. Recent developments in drug targeting against chemokine receptors highlights the need for further understanding of the role played by these proteins and their receptors in many different diseases. PMID- 27707419 TI - Molecular characterization and detection of variants of Taenia multiceps in sheep in Turkey. AB - Taenia multiceps is a cestode (family Taeniidae) that in its adult stage lives in the small intestine of dogs and other canids. The metacestode, known as Coenurus cerebralis, is usually found in the central nervous system including brain and spinal card in sheep and other ruminants. The presence of cysts typically leads to neurological symptoms that in the majority of cases result in the death of the animal. Coenurosis could cause high losses in sheep farms because the disease commonly affects young animals. A total of 20 C. cerebralis isolates collected from naturally infected sheep in Mardin province of Turkey were characterized through the polymerase chain reaction and sequencing of a fragment of cytochrome c oxidase subunit 1 (CO1) gene. The results showed that the CO1 gene sequences were highly conserved in C. cerebralis isolates. Phylogenetic analysis based on partial CO1 gene sequences revealed that C. cerebralis isolates were composed of three different variants. PMID- 27707420 TI - Molecular characterization of 5S ribosomal RNA genes and transcripts in the protozoan parasite Leishmania major. AB - Eukaryotic 5S rRNA, synthesized by RNA polymerase III (Pol III), is an essential component of the large ribosomal subunit. Most organisms contain hundreds of 5S rRNA genes organized into tandem arrays. However, the genome of the protozoan parasite Leishmania major contains only 11 copies of the 5S rRNA gene, which are interspersed and associated with other Pol III-transcribed genes. Here we report that, in general, the number and order of the 5S rRNA genes is conserved between different species of Leishmania. While in most organisms 5S rRNA genes are normally associated with the nucleolus, combined fluorescent in situ hybridization and indirect immunofluorescence experiments showed that 5S rRNA genes are mainly located at the nuclear periphery in L. major. Similarly, the tandemly repeated 5S rRNA genes in Trypanosoma cruzi are dispersed throughout the nucleus. In contrast, 5S rRNA transcripts in L. major were localized within the nucleolus, and scattered throughout the cytoplasm, where mature ribosomes are located. Unlike other rRNA species, stable antisense RNA complementary to 5S rRNA is not detected in L. major. PMID- 27707421 TI - Narrow band imaging versus autofluorescence imaging for head and neck squamous cell carcinoma detection: a prospective study. AB - OBJECTIVES: This study aimed to compare the diagnostic effectiveness of narrow band imaging and autofluorescence imaging for malignant laryngopharyngeal tumours. METHODS: Between May 2010 and October 2010, 50 consecutive patients with suspected laryngopharyngeal tumour underwent endoscopic laryngopharynx examination. The morphological characteristics of laryngopharyngeal lesions were analysed using high performance endoscopic systems equipped with narrow band imaging and autofluorescence imaging modes. The diagnostic effectiveness of white light image, narrow band imaging and autofluorescence imaging endoscopy for benign and malignant laryngopharyngeal lesions was evaluated. RESULTS: Under narrow band imaging endoscopy, the superficial microvessels of squamous cell carcinomas appeared as dark brown spots or twisted cords. Under autofluorescence imaging endoscopy, malignant lesions appeared as bright purple. The sensitivity of malignant lesion diagnosis was not significantly different between narrow band imaging and autofluorescence imaging modes, but was better than for white light image endoscopy (chi2 = 12.676, p = 0.002). The diagnostic specificity was significantly better in narrow band imaging mode than in both autofluorescence imaging and white light imaging mode (chi2 = 8.333, p = 0.016). CONCLUSION: Narrow band imaging endoscopy is the best option for the diagnosis and differential diagnosis of laryngopharyngeal tumours. PMID- 27707422 TI - Current demand of paediatric otolaryngology input for children with Down's syndrome in a tertiary referral centre. AB - OBJECTIVE: This study aimed to evaluate the activity of paediatric otolaryngology services required for children with Down's syndrome in a tertiary referral centre. METHODS: A review of the paediatric otolaryngology input for children with Down's syndrome was performed; data were obtained from the coding department for a two-year period and compared with other surgical specialties. RESULTS: Between June 2011 and May 2013, 106 otolaryngology procedures were performed on children with Down's syndrome. This compared to 87 cardiac and 81 general paediatrics cases. The most common pathologies in children with Down's syndrome were obstructive sleep apnoea, otitis media, hearing loss and cardiac disease. The most common otolaryngology procedures performed were adenoidectomy, tonsillectomy, grommet insertion and bone-anchored hearing aid implant surgery. CONCLUSION: ENT manifestations of Down's syndrome are common. Greater provisions need to be made to streamline the otolaryngology services for children and improve transition of care to adult services. PMID- 27707423 TI - Impact of Ultraviolet Germicidal Irradiation for No-Touch Terminal Room Disinfection on Clostridium difficile Infection Incidence Among Hematology Oncology Patients. AB - OBJECTIVE To evaluate the impact of no-touch terminal room no-touch disinfection using ultraviolet wavelength C germicidal irradiation (UVGI) on C. difficile infection (CDI) rates on inpatient units with persistently high rates of CDI despite infection control measures. DESIGN Interrupted time-series analysis with a comparison arm. SETTING 3 adult hematology-oncology units in a large, tertiary care hospital. METHODS We conducted a 12-month prospective valuation of UVGI. Rooms of patients with CDI or on contact precautions were targeted for UVGI upon discharge using an electronic patient flow system. Incidence rates of healthcare onset CDI were compared for the baseline period (January 2013-December 2013) and intervention period (February 2014-January 2015) on study units and non-study units using a mixed-effects Poisson regression model with random effects for unit and time in months. RESULTS During a 52-week intervention period, UVGI was deployed for 542 of 2,569 of all patient discharges (21.1%) on the 3 study units. The CDI rate declined 25% on study units and increased 16% on non-study units during the intervention compared to the baseline period. We detected a significant association between UVGI and decrease in CDI incidence (incidence rate ratio [IRR], 0.49; 95% confidence interval [CI], 0.26-0.94; P=.03) on the study units but not on the non-study units. The impact of UVGI use on average room-cleaning time and turnaround time was negligible compared to the baseline period. CONCLUSIONS Targeted deployment of UVGI to rooms of high-risk patients at discharge resulted in a substantial reduction of CDI incidence without adversely impacting room turnaround.

AB - OBJECTIVE: To systematically search for studies reporting outcomes for adenoidectomy alone as a treatment for paediatric obstructive sleep apnoea and use the data to perform a meta-analysis. METHODS: Nine databases, including PubMed and Medline, were systematically searched through to 1 April 2016. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was followed. RESULTS: A total of 1032 articles were screened and 126 full texts were reviewed. Three paediatric studies (47 patients) reported outcomes. Overall, apnoea-hypopnoea index values decreased from 18.1 +/- 16.8 to 3.1 +/- 5.5 events per hour (28 patients). Random-effects modelling demonstrated a mean difference of -14.43 events per hour (I2 = 23 per cent (low inconsistency)). The apnoea hypopnoea index standardised mean difference was -1.14 (large magnitude of effect). The largest reduction in apnoea-hypopnoea index was observed in children aged less than 12 months (reduction of 56.6-94.9 per cent). Lowest oxygen saturation values improved from 80.0 +/- 9.5 to 85.5 +/- 6.0 per cent (13 children). CONCLUSION: Adenoidectomy alone has improved obstructive sleep apnoea in children, especially in those aged less than 12 months; however, given the low number of studies, isolated adenoidectomy remains an area for additional research. PMID- 27707425 TI - Can curcumin modulate allergic rhinitis in rats? AB - OBJECTIVES: This study aimed to explore the effects of curcumin on experimental allergic rhinitis in rats. METHODS: Twenty-eight male Wistar albino rats were randomly divided into four groups: a control group; a group in which allergic rhinitis was induced and no treatment given; a group in which allergic rhinitis was induced followed by treatment with azelastine hydrochloride on days 21-28; and a group in which allergic rhinitis was induced followed by treatment with curcumin on days 21-28. Allergy symptoms and histopathological features of the nasal mucosa were examined. RESULTS: The sneezing and nasal congestion scores were higher in the azelastine and curcumin treatment groups than in the control group. Histopathological examination showed focal goblet cell metaplasia on the epithelial surface in the azelastine group. In the curcumin group, there was a decrease in goblet cell metaplasia in the epithelium, decreased inflammatory cell infiltration and vascular proliferation in the lamina propria. CONCLUSION: Curcumin is an effective treatment for experimentally induced allergic rhinitis in rats. PMID- 27707426 TI - Summer time predation on the obligatory off-host stage of an invasive ectoparasite. AB - Predation can regulate populations and strongly affect invasion success of novel prey. The deer ked (Lipoptena cervi; Linnaeus 1758) is an invasive ectoparasite of cervids that spends a long period of its life cycle outside the host. Prior to this study, virtually nothing was known about natural summer time predation on the deer ked. We aimed to evaluate the magnitude of summer time predation on L. cervi pupae in different habitats and to identify potential predators. We conducted a set of field experiments, where we exposed L. cervi pupae to various ground-dwelling vertebrate and invertebrate predators. The loss of pupae was monitored for different predator guilds. Three habitats of the moose, the main host species, were studied: (1) moist heath forest; (2) dry, logged heath forest; and (3) moist meadow. The results indicate notable summer time predation on L. cervi pupae, and the pupal predation varied within and between habitats, being lowest in the meadow habitat. We found a positive correlation between pupal loss and abundance of the common lizard (Zootoca vivipara), harvestmen (Opiliones), ground spiders (Gnaphosidae) and Formicinae-ants. We conclude that summer time predation during the pupal phase can have a notable local importance for the L. cervi abundance. PMID- 27707427 TI - Verrucosispora sonchi sp. nov., a novel endophytic actinobacterium isolated from the leaves of common sowthistle (Sonchus oleraceus L.). AB - A novel actinobacterium, designated strain NEAU-QY3T, was isolated from the leaves of Sonchus oleraceus L. and examined using a polyphasic taxonomic approach. The organism formed single spores with smooth surface on substrate mycelia. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that the strain had a close association with the genus Verrucosispora and shared the highest sequence similarity with Verrucosispora qiuiae RtIII47T (99.17 %), an association that was supported by a bootstrap value of 94 % in the neighbour joining tree and also recovered with the maximum-likelihood algorithm. The strain also showed high 16S rRNA gene sequence similarities to Xiangella phaseoli NEAU J5T (98.78 %), Jishengella endophytica 202201T (98.51 %), Micromonospora eburnea LK2-10T (98.28 %), Verrucosispora lutea YIM 013T (98.23 %) and Salinispora pacifica CNR-114T (98.23 %). Furthermore, phylogenetic analysis based on the gyrB gene sequences supported the conclusion that strain NEAU-QY3T should be assigned to the genus Verrucosispora. However, the DNA-DNA hybridization relatedness values between strain NEAU-QY3T and V. qiuiae RtIII47T and V. lutea YIM 013T were below 70 %. With reference to phenotypic characteristics, phylogenetic data and DNA-DNA hybridization results, strain NEAU-QY3T was readily distinguished from its most closely related strains and classified as a new species, for which the name Verrucosispora sonchi sp. nov. is proposed. The type strain is NEAU-QY3T (=CGMCC 4.7312T=DSM 101530T). PMID- 27707428 TI - Metabolite profiling of Phycomyces blakesleeanus carotene mutants reveals global changes across intermediary metabolism. AB - The filamentous fungus Phycomyces blakesleeanus provides a renewable biosource of industrial high-value compounds such as carotenes, other isoprenoids (ubiquinone and sterols), organic acids and fatty acids. Several Phycomyces mutants involved in the formation of beta-carotene are available. For example, the carA mutants have a leaky mutation in the phytoene synthase and produce significantly lower amounts of carotenes, while the carB and carR mutants produce phytoene and lycopene, respectively, due to a null mutation in the genes encoding the phytoene dehydrogenase and lycopene cyclase, respectively. The carS mutants are mutated in the gene encoding the oxygenase responsible for the conversion of beta-carotene into apocarotenoids and, as a result, beta-carotene accumulates. In order to ascertain further the biochemical changes arising in these potential industrial strains, a metabolite profiling workflow was implemented for Phycomyces. GC-MS and ultra-performance liquid chromatography-photodiode array platforms enabled the identification of over 100 metabolites in 11 carA, carB, carR and carS mutant strains and their wild-type comparator. All mutant strains possessed decreased TCA cycle intermediates, galactose, alanine and ribitol, while dodecanol and valine showed a general increase. As predicted, other terpenoid levels were affected in the carB, carR and carS mutants but not in the carA mutants. The global changes across intermediary metabolism of the mutants suggest that complex metabolic networks exist between intermediary and secondary metabolism or that other mutations beyond the carotene pathway may exist in these mutants. These data show the utility of the methodology in metabolically phenotyping Phycomyces strains with potential industrial exploitation. PMID- 27707429 TI - Three novel species of coccoid green algae within the Watanabea clade (Trebouxiophyceae, Chlorophyta). AB - Coccoid green algae are extremely diverse despite their simple coccoid phenotype, a phenotype that may be the result of convergent evolution. In this study, we used a polyphasic approach combining molecular phylogenetic analyses, morphology and ultrastructure to investigate isolated coccoid strains from China, and our results reveal three new lineages of Trebouxiophyceae: the novel genus and species Mysteriochloris nanningensis gen. et sp. nov., and the two novel species Phyllosiphon coccidium sp. nov. and Desertella yichangensis sp. nov. (Trebouxiophyceae, Chlorophyta). We provide a detailed characterization of the novel microalgae which they are autosporic coccoid unicells and have parietal chloroplasts. In phylogenies based on 18S rDNA sequences and the chloroplast ribulose-bisphosphate carboxylase gene (rbcL), these three algae are nested within the Watanabea clade and are different from any known algae. M. nanningensis FACHB-1787 is not really close to any known algae within the Watanabea clade. Phyllosiphoncoccidium FACHB-2212 is within the Phyllosiphon lineages. D. yichangensis FACHB-1793 is closely related to Desertella californica and described as a representative of a novel species of the genus Desertella. PMID- 27707430 TI - Luteimonas padinae sp. nov., an epiphytic bacterium isolated from an intertidal macroalga. AB - A Gram-stain-negative, rod-shaped bacterium, forming yellow colonies and designated CDR SL 15T, was isolated from the surface of Padina sp., a brown macroalga, which grows in the Western coastal regions of the state of Goa, India. The 16S rRNA gene sequence phylogeny placed the strain in the genus Luteimonas and it showed closest sequence similarity to Luteimonas terricola BZ92rT (97.6 %) and <97.0 % to other species of the genus Luteimonas. Chemotaxonomic features, such as having iso-C15 : 0 and summed feature 9 (C16 : 0 10-methyl/iso-C17 : 1omega9c) as the major fatty acids and Q-8 as the only ubiquinone further supported its placement within this genus. There were some critical differences in phenotypic properties between Luteimonas padinae sp. nov. CDR SL 15T and L. terricola DSM 22344T i.e. temperature range for growth and salinity range and optimum for growth (L. terricola is a psychrotolerant bacterium with a lower optimum temperature for growth), acid production and assimilation of substrates, enzyme activities and resistance to certain antibiotics. The DNA-DNA relatedness value of the novel strain with its closest phylogenetic relative was only 40 %, below the 70 % threshold value recommended for species delineation. All these characteristics are consistent with strain CDR SL 15T representing a novel species of the genus Luteimonas, for which the name Luteimonas padinae sp. nov. is proposed. The type strain is CDR SL 15T (=DSM 101536T=KCTC 52403T). PMID- 27707431 TI - Algoriphagus litorisediminis sp. nov., isolated from a tidal flat. AB - A Gram-stain-negative, non-flagellated, non-gliding, aerobic and rod-shaped bacterium, designated strain OITF-19T, was isolated from a tidal flat in Oido, an island of South Korea, and subjected to a polyphasic taxonomic study. Strain OITF 19T grew optimally at 30 degrees C, at pH 7.0-8.0 and in the presence of 2.0 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain OITF-19T belonged to the genus Algoriphagus, clustering with the type strain of Algoriphagus namhaensis, with which it shared 96.5 % sequence similarity. Strain OITF-19T exhibited the highest 16S rRNA gene sequence similarity to Algoriphagus chungangensis CAU 1002T (97.0 %) and of 92.0 96.8 % to the type strains of other Algoriphagus species. Strain OITF-19T contained MK-7 as the predominant menaquinone and summed feature 3 (C16 : 1omega7c and/or C16 : 1omega6c), iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids detected in strain OITF-19T were phosphatidylcholine, phosphatidylethanolamine and three unidentified lipids. The DNA G+C content of strain OITF-19T was 38.3 mol%. Mean DNA-DNA relatedness between strain OITF-19T and the type strain of A. chungangensis was 26 %. Differential phenotypic properties, together with its phylogenetic and genetic distinctiveness, revealed that strain OITF-19T is separated from recognized species of the genus Algoriphagus. On the basis of the data presented, strain OITF-19T is considered to represent a novel species of the genus Algoriphagus, for which the name Algoriphagus litorisediminis sp. nov. is proposed. The type strain is OITF-19T (=KCTC 52456T=NBRC 112418T). PMID- 27707432 TI - Redefining homonyms under Rule 51b (4) of the International Code of Nomenclature of Prokaryotes.

PMID- 27707433 TI - Nakamurella silvestris sp. nov., an actinobacterium isolated from alpine forest soil. AB - A Gram-stain-positive, non-motile, catalase-positive and cytochrome c oxidase negative bacterium, designated strain S20-107T, was isolated from alpine forest soil. Growth occurred at 0-30 degrees C, at pH 6-9 and in the presence of 0-3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S20-107T was related to the genus Nakamurella and had the highest 16S rRNA gene sequence similarity with Nakamurella flavida DS-52T (96.1 %). Strain S20 107T showed <96.1% 16S rRNA gene sequence similarities to all other recognized members of the genus Nakamurella. The cell-wall peptidoglycan contained meso diaminopimelic acid. The major whole-cell sugars were glucose, galactose, mannose, arabinose, ribose and rhamnose. The strain contained MK-8(H4) as the predominant menaquinone and diphosphatidylglycerol, phosphatidylethanolamine and an unidentified aminophospholipid as the major polar lipids. The major cellular fatty acids were anteiso-C15 : 0, C16 : 0, summed feature 3 (C16 : 1omega6c and/or C16 : 1omega7c and/or iso-C15 : 0 2-OH) and iso-C16 : 0. The genomic DNA G+C content was 70.5 mol%. Combined data of phylogenetic, phenotypic and chemotaxonomic analyses demonstrated that strain S20-107T represents a novel species of the genus Nakamurella, for which the name Nakamurella silvestris sp. nov. is proposed. The type strain is S20-107T (=DSM 102309T=LMG 29427T). PMID- 27707434 TI - Identification and taxonomic characterization of Bordetella pseudohinzii sp. nov. isolated from laboratory-raised mice. AB - Bordetella hinzii is known to cause respiratory disease in poultry and has been associated with a variety of infections in immunocompromised humans. In addition, there are several reports of B. hinzii infections in laboratory-raised mice. Here we sequenced and analysed the complete genome sequences of multiple B. hinzii like isolates, obtained from vendor-supplied C57BL/6 mice in animal research facilities on different continents, and we determined their taxonomic relationship to other Bordetella species. The whole-genome based and 16S rRNA gene based phylogenies each identified two separate clades in B. hinzii, one was composed of strains isolated from poultry, humans and a rabbit whereas the other clade was restricted to isolates from mice. Distinctly different estimated DNA DNA hybridization values, average nucleotide identity scores, gene content, metabolic profiles and host specificity all provide compelling evidence for delineation of the two species, B. hinzii - from poultry, humans and rabbit - and Bordetella pseudohinzii sp. nov. type strain 8-296-03T (=NRRL B-59942T=NCTC 13808T) that infect mice. PMID- 27707435 TI - Progression of Polysomnographic Abnormalities in Mucolipidosis II (I-Cell Disease). AB - ABSTRACT: Mucolipidosis II (Inclusion cell or I-cell disease) is an autosomal recessive lysosomal storage disorder clinically comparable to the mucopolysaccharidoses (MPS), characterized by progressive respiratory and neurologic deterioration. Sleep problems, especially obstructive sleep apnea (OSA) and disrupted sleep architecture, are observed in other lysosomal storage diseases but have not been described in mucolipidosis II. We report the progression of polysomnographic abnormalities in a child with mucolipidosis II, demonstrated by worsening sleep-related hypoventilation, OSA, and sleep state fragmentation despite advancing PAP therapy. Background slowing and reduction in spindle activity on limited EEG may reflect progressive CNS disease affecting thalamic neurons. PMID- 27707436 TI - Treatment of OSA with CPAP Is Associated with Improvement in PTSD Symptoms among Veterans. AB - STUDY OBJECTIVES: Posttraumatic stress disorder (PTSD) is common among veterans of the military, with sleep disturbance as a hallmark manifestation. A growing body of research has suggested a link between obstructive sleep apnea and PTSD, potentially due to obstructive sleep apnea (OSA) related sleep disruption, or via other mechanisms. We examined the hypothesis that treatment of OSA with positive airway pressure would reduce PTSD symptoms over 6 months. METHODS: A prospective study of Veterans with confirmed PTSD and new diagnosis of OSA not yet using PAP therapy were recruited from a Veteran's Affairs sleep medicine clinic. All subjects were instructed to use PAP each night. Assessments were performed at 3 and 6 months. The primary outcome was a reduction in PTSD symptoms at 6 months. RESULTS: Fifty-nine subjects were enrolled; 32 remained in the study at 6 months. A significant reduction in PTSD symptoms, measured by PCL-S score was observed over the course of the study (60.6 +/- 2.7 versus 52.3 +/- 3.2 points; p < 0.001). Improvement was also seen in measures of sleepiness, sleep quality, and daytime functioning, as well as depression and quality of life. Percentage of nights in which PAP was used, but not mean hours used per night, was predictive of improvement. CONCLUSIONS: Treatment of OSA with PAP therapy is associated with improvement in PTSD symptoms, although the mechanism is unclear. Nonetheless, PAP should be considered an important component of PTSD treatment for those with concurrent OSA. Improving PAP compliance is a challenge in this patient population warranting further investigation. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02019914. COMMENTARY: A commentary on this article appears in this issue on page 5. PMID- 27707437 TI - Association between Sleep Duration and Self-Reported Health Status: Findings from the Bhutan's Gross National Happiness Study. AB - STUDY OBJECTIVES: Short and long sleep durations have been found to be associated with chronic conditions like diabetes mellitus, hypertension and cardiovascular disease. However, most studies were conducted in developed countries and the results were inconsistent. The aim of this study is to investigate the association between sleep duration and self-reported health status in a developing country setting. METHODS: We conducted secondary data analysis of the 2010 Gross National Happiness study of Bhutan, which was a nationwide cross sectional study with representative samples from rural and urban areas. The study included 6476 participants aged 15-98 y. The main outcome variable of interest was self-reported health status. Sleep duration was categorized as <= 6 h, 7 h, 8 h, 9 h, 10 h, and >= 11 h. Multiple logistic regressions were conducted to investigate the association between sleep duration and self-reported health status. RESULTS: The mean sleep duration was 8.5 (+/- 1.65) h. Only 9% of the respondents slept for 7 h; 6% were short sleepers (<= 6 h) and 84% were long sleepers (21%, 8 h; 28%, 9 h; 22%, 10 h; 13%, >= 11 h). We found that both short (<= 6 h) and long sleep duration (>= 11 h) were independently associated with poor self-reported health status. CONCLUSIONS: This study found that people with shorter and longer sleep durations were more likely to report poorer health status. PMID- 27707438 TI - Validation of a Wireless, Self-Application, Ambulatory Electroencephalographic Sleep Monitoring Device in Healthy Volunteers. AB - STUDY OBJECTIVES: To evaluate the validity of an ambulatory electroencephalographic (EEG) monitor for the estimation of sleep continuity and architecture in healthy adults. METHODS: Healthy, good sleeping participants (n = 14) were fit with both an ambulatory EEG monitor (Sleep Profiler) and a full polysomnography (PSG) montage. EEG recordings were gathered from both devices on the same night, during which sleep was permitted uninterrupted for eight hours. The study was set in an inpatient clinical research suite. PSG and Sleep Profiler records were scored by a neurologist board certified in sleep medicine, blinded to record identification. Agreement between the scored PSG record, the physician scored Sleep Profiler record, and the Sleep Profiler record scored by an automatic algorithm was evaluated for each sleep stage, with the PSG record serving as the reference. RESULTS: Results indicated strong percent agreement across stages. Kappa was strongest for Stage N3 and REM. Specificity was high for all stages; sensitivity was low for Wake and Stage N1, and high for Stage N2, Stage N3, and REM. Agreement indices improved for the manually scored Sleep Profiler record relative to the autoscore record. CONCLUSIONS: Overall, the Sleep Profiler yields an EEG record with comparable sleep architecture estimates to PSG. Future studies should evaluate agreement between devices with a clinical sample that has greater periods of wake in order to better understand utility of this device for estimating sleep continuity indices, such as sleep onset latency and wake after sleep onset. PMID- 27707439 TI - Factors Associated with Changes in Invasive and Noninvasive Positive Airway Pressure Therapy Settings during Pediatric Polysomnograms. AB - STUDY OBJECTIVES: Our aim was to identify clinical predictors associated with changes in settings for pediatric invasive and noninvasive positive airway pressure therapy, which could help inform the allocation of limited polysomnogram (PSG) resources. METHODS: A retrospective review was conducted in children who underwent one or more PSGs for technology titration. Children were included if they were using continuous positive airway pressure (CPAP) therapy, bilevel positive airway pressure (BPAP) therapy, or invasive positive pressure ventilation (IPPV) the night of the PSG. The primary outcome measure for the study were predictors of change in settings during IPPV, CPAP, and BPAP titration studies. RESULTS: During the study period, 274 children using CPAP, BPAP, or IPPV underwent one or more titration PSGs. The mean (standard deviation [SD]) age of the children at the time of the first titration PSG was 10.52 (5.11) y. Fifty percent (n = 136) of the study participants were male. Most patients underwent BPAP titration studies (n = 166), followed by CPAP (n = 83) and then IPPV (n = 25). A total of 623 technology titration PSGs were completed. Reason for respiratory technology, type of respiratory technology, and time between ventilation initiation and the PSG were significant predictors of a change in settings in the multivariable regression model. CONCLUSIONS: Children were more likely to have a change in their technology settings during a PSG if there was a shorter period of time from the original technology initiation, if they were using BPAP (as compared to CPAP or IPPV) and/or if they had a primary central nervous system or musculoskeletal diagnosis. PMID- 27707440 TI - Vitamin D Improves Selected Metabolic Parameters but Not Neuropsychological or Quality of Life Indices in OSA: A Pilot Study. AB - STUDY OBJECTIVES: Our group and others have reported a high rate of vitamin D deficiency in obstructive sleep apnea (OSA), where vitamin D levels (25(OH) D) correlate negatively with OSA severity and some of its associated metabolic alterations. Data regarding vitamin D supplementation in OSA are lacking. We wanted to evaluate the effect of vitamin D3 supplementation on OSA symptoms and metabolic parameters. METHODS: We conducted a pilot, double-blind, randomized, placebo-controlled trial of daily supplementation with 4,000 IU vitamin D3 (D3) or placebo (PL). We studied 19 Caucasian adults (14 male, mean age 55 y, mean body mass index [BMI] 30.4 kg/m2) with OSA. Fifteen patients were stable on continuous positive airways pressure (CPAP) therapy, whereas four were CPAP naive. Assessments were completed at baseline and after 15 weeks of supplementation. Outcomes included sleepiness (Epworth Sleepiness Scale), quality of life (Sleep Apnea Quality of Life Inventory), fatigue (fatigue severity scale) and neuropsychological function (trail making test and Connor's Continuous Performance Test II). In addition, we assessed biochemical indices of vitamin D status (25(OH)D, calcium), inflammation (high sensitivity C-reactive protein, and lipoprotein-associated phospholipase A2), lipids (total cholesterol [low-density and high-density lipoprotein]) and glycemic indices (fasting glucose, oral glucose tolerance test). RESULTS: There was no change in BMI, medication, or CPAP usage. Although there was no change in neuropsychological or quality of life indices, we observed a significant increase in 25(OH)D (p = 0.00001) and significant decreases in both low-density lipoprotein (p = 0.04) and lipoprotein associated phospholipase A2 (p = 0.037) as well as trends toward decreased fasting glucose (p = 0.09) and increased high-density lipoprotein (p = 0.07) in the D3 group compared to PL. CONCLUSIONS: Vitamin D3 supplementation increased vitamin D levels and decreased metabolic markers compared to placebo. Larger trials are required. PMID- 27707441 TI - Effect of Manual Editing of Total Recording Time: Implications for Home Sleep Apnea Testing. AB - STUDY OBJECTIVES: Type 3 home sleep apnea tests may underestimate the apnea hypopnea index (AHI) due to overestimation of total sleep time (TST). We aimed to evaluate the effect of manual editing of the total recording time (TRT) on the TST and AHI. METHODS: Thirty 15-channel in-home polysomnography studies (AHI 0 to 30 events/h) scored using American Academy of Sleep Medicine criteria were rescored by two blinded polysomnologists after data from electroencephalogram, electrooculogram, and electromyogram were masked. In method 1, periods of probable wakefulness and artifact were manually edited and removed from analysis. Method 2 identified TST as the TRT without manual editing. Paired t-tests were used to compare the TST and AHI between these methods. Sensitivity and specificity of each method were calculated for gold standard AHI cutoffs of >= 5 and >= 15 events/h. RESULTS: TST (mean [standard deviation, SD]) by polysomnography, method 1, and method 2 was 366.0 (70.1), 447.1 (59.0), and 542 (61.9) min, respectively. The corresponding AHI was 12.5 (8.2), 10.8 (7.0), and 9.1 (6.1) events/h, respectively. Compared to polysomnography, both alternative methods overestimated the TST (method 1: mean difference [SD] 81.1 [56.1] min, method 2: 176.0 [89.7] min; both p < 0.001) and underestimated the AHI (method 1: mean difference [SD] -1.6 [3.3], method 2: -3.3 [3.9]; both p < 0.001). The sensitivity was 100% and 70.0% for method 1, and 91.3% and 40.0% for method 2 for identifying sleep-disordered breathing using AHI cutoffs of >= 5 and >= 15 events/h, respectively. CONCLUSIONS: Manual editing of TRT reduces the overestimation of TST and improves the sensitivity for identifying studies with sleep-disordered breathing. COMMENTARY: A commentary on this article appears in this issue on page 9. PMID- 27707442 TI - Nasal Dilator Strip is an Effective Placebo Intervention for Severe Obstructive Sleep Apnea. AB - STUDY OBJECTIVES: The aim of this study was to evaluate the effects of nasal dilator strip (NDS) as a placebo intervention compared with continuous positive airway pressure (CPAP) treatment in patients with severe obstructive sleep apnea (OSA). METHODS: Patients were treated with both NDS and nasal CPAP. The sequence was randomized and interposed by 15 days of washout. Polysomnography was performed at baseline and on the first night of intervention with NDS and CPAP (titration). The Epworth Sleepiness Scale (ESS), Functional Outcomes of Sleep Questionnaire (FOSQ), and Beck Depression Inventory (BDI) were completed at baseline and at the end of both interventions. A questionnaire on the comfort and satisfaction (0 = no to 10 = total) was completed at the end of each intervention. RESULTS: Twenty-six patients with OSA were evaluated (19 male; age 46.3 +/- 9.3 y; body mass index 33.2 +/- 5.1 kg/m2; ESS 15.8 +/- 4.1; apnea hypopnea index 60.7 +/- 25.2). Adherence was high in both NDS (98%) and CPAP interventions (94%; 5.8 +/- 1.7 h/night). In contrast to the baseline values, NDS intervention had no significant effect on all polysomnographic parameters, but NDS improved somnolence (ESS 13.0 +/- 5.4, p = 0.001) and depressive symptoms (BDI 7.7 +/- 6.9, p = 0.005). Reported satisfaction was significantly higher for CPAP than for NDS (sleep quality 9.2 +/- 0.8 vs. 6.1 +/- 2.1; wake up at morning: 8.6 +/- 1.2 vs. 6.0 +/- 2.2; daily activities: 8.9 +/- 1.4 vs. 5.8 +/- 1.5; quality of life: 8.3 +/- 2.1 vs. 3.8 +/- 3.5, p < 0.001), but similar low levels of difficulty for both interventions were observed (1.3 +/- 2.2 vs. 0.3 +/- 1.3, p = 0.098). CONCLUSIONS: Our data indicate that NDS is an attractive placebo intervention for randomized controlled trials evaluating the effects of CPAP in sleepy patients with OSA. PMID- 27707444 TI - An Unexpected Polysomnogram Finding. PMID- 27707443 TI - Growing Up with Type 1 Narcolepsy: Its Anthropometric and Endocrine Features. AB - STUDY OBJECTIVES: To evaluate the effect of type 1 narcolepsy (NT1) on anthropometric and endocrine features in childhood/adolescence, focusing on patterns and correlates of weight, pubertal development, and growth in treated and untreated patients. METHODS: We collected anthropometric (height, weight, body mass index (BMI) z-scores), pubertal, metabolic, and endocrine data from 72 NT1 patients at diagnosis and all available premorbid anthropometric parameters of patients from their pediatric files (n = 30). New measurements at 1-y reassessment in patients undergoing different treatments were compared with baseline data. RESULTS: We detected a high prevalence of overweight (29.2%), obesity (25%), metabolic syndrome (18.8%), and precocious puberty (16.1%), but no signs of linear growth alterations at diagnosis. According to anthropometric records, weight gain started soon after NT1 onset. At 1-y follow-up reassessment, sodium oxybate treatment was associated with a significant BMI z-score reduction (-1.29 +/- 0.30, p < 0.0005) after adjusting for baseline age, sex, sleepiness, and BMI. CONCLUSIONS: NT1 onset in children/adolescents is associated with rapid weight gain up to overweight/obesity and precocious puberty without affecting growth. In our study, sodium oxybate treatment resulted in a significant weight reduction in NT1 overweight/obese patients at 1-y follow-up.

PMID- 27707449 TI - Ventilatory Cycle Measurements and Loop Gain in Central Apnea in Mining Drivers Exposed to Intermittent Altitude. AB - STUDY OBJECTIVES: By measuring the apnea length, ventilatory phase, respiratory cycle length, and loop gain, we can further characterize the central apneas of high altitude (CAHA). METHODS: Sixty-three drivers of all-terrain vehicles, working in a Peruvian mine located at 2,020 meters above sea level (MASL), were evaluated. A respiratory polygraph was performed in the first night they slept at high altitude. None of the subjects were exposed to oxygen during the test or acetazolamide in the preceding days of the test. RESULTS: Sixty-three respiratory polygraphs were performed, and 59 were considered for analysis. Forty-six (78%) were normal, 6 (10%) had OSA, and 7 (12%) had CAHA. Key data from subjects include: residing altitude: 341 +/- 828 MASL, Lake Louise scoring: 0.4 +/- 0.8, Epworth score: 3.4 +/- 2.7, apneahypopnea index: 35.7 +/- 19.3, CA index: 13.4 +/ 14.2, CA length: 14.4 +/- 3.6 sec, ventilatory length: 13.5 +/- 2.9 sec, cycle length: 26.5 +/- 4.0 sec, ventilatory length/CA length ratio 0.9 +/- 0.3 and circulatory delay 13.3 +/- 2.9 sec. Duty ratio media [ventilatory duration/cycle duration] was 0.522 +/- 0 0.128 [0.308-0.700] and loop gain was calculated from the duty ratio utilizing this formula: LG = 2pi / [(2piDR-sin(2piDR)]. All subjects have a high loop gain media 2.415 +/- 1.761 [1.175-6.260]. Multiple correlations were established with loop gain values, but the only significant correlation detected was between central apnea index and loop gain. CONCLUSIONS: Twelve percent of the studied population had CAHA. Measurements of respiratory cycle in workers with CAHA are more similar to idiopathic central apneas rather than Hunter-Cheyne-Stokes respiration. Also, there was a high degree of correlation between severity of central apnea and the degree of loop gain. The abnormal breathing patterns in those subjects could affect the sleep quality and potentially increase the risk for work accidents. PMID- 27707448 TI - Reliability of Actigraphy and Subjective Sleep Measurements in Adults: The Design of Sleep Assessments. AB - STUDY OBJECTIVES: The aim of the study was to investigate how many nights of measurement are needed for a reliable measure of sleep in a working population including adult women and men. METHODS: In all, 54 individuals participated in the study. Sleep was assessed for 7 consecutive nights using actigraphy as an objective measure, and the Karolinska sleep diary for a subjective measure of quality. Using intra-class correlation and the Spearman-Brown formula, calculations of how many nights of measurements were required for a reliable measure were performed. Differences in reliability according to whether or not weekend measurements were included were investigated. Further, the correlation between objectively (actigraphy) measured sleep and subjectively measured sleep quality was studied over the different days of the week. RESULTS/CONCLUSIONS: The results concerning actigraphy sleep measures suggest that data from at least 2 nights are to be recommended when assessing sleep percent and at least 5 nights when assessing sleep efficiency. For actigraphy-measured total sleep time, more than 7 nights are needed. At least 6 nights of measurements are required for a reliable measure of self-reported sleep. Fewer nights (days) are required if measurements include only week nights. Overall, there was a low correlation between the investigated actigraphy sleep parameters and subjective sleep quality, suggesting that the two methods of measurement capture different dimensions of sleep. PMID- 27707447 TI - Consensus Statement of the American Academy of Sleep Medicine on the Recommended Amount of Sleep for Healthy Children: Methodology and Discussion. AB - ABSTRACT: Members of the American Academy of Sleep Medicine developed consensus recommendations for the amount of sleep needed to promote optimal health in children and adolescents using a modified RAND Appropriateness Method. After review of 864 published articles, the following sleep durations are recommended: Infants 4 months to 12 months should sleep 12 to 16 hours per 24 hours (including naps) on a regular basis to promote optimal health. Children 1 to 2 years of age should sleep 11 to 14 hours per 24 hours (including naps) on a regular basis to promote optimal health. Children 3 to 5 years of age should sleep 10 to 13 hours per 24 hours (including naps) on a regular basis to promote optimal health. Children 6 to 12 years of age should sleep 9 to 12 hours per 24 hours on a regular basis to promote optimal health. Teenagers 13 to 18 years of age should sleep 8 to 10 hours per 24 hours on a regular basis to promote optimal health. Sleeping the number of recommended hours on a regular basis is associated with better health outcomes including: improved attention, behavior, learning, memory, emotional regulation, quality of life, and mental and physical health. Regularly sleeping fewer than the number of recommended hours is associated with attention, behavior, and learning problems. Insufficient sleep also increases the risk of accidents, injuries, hypertension, obesity, diabetes, and depression. Insufficient sleep in teenagers is associated with increased risk of self-harm, suicidal thoughts, and suicide attempts. COMMENTARY: A commentary on this article apears in this issue on page 1439. PMID- 27707451 TI - They need to be recognized as a person in everyday life: Teachers' and helpers' experiences of teacher-student relationships in upper secondary school. AB - The aim of this study was to explore how teachers and helpers experience that teacher-student relationship (TSR) is developed and promoted in upper secondary school.We also explored their experiences of qualities of TSR with students with mental health problems or at risk of dropping out. The study used a qualitative and participative approach; key stakeholders were included as co-researchers. Focus group interviews were held with 27 teachers and helpers. A thematic analysis was conducted. The participants' descriptions of important experiential dimensions of TSR were clustered around four themes: (1) to be recognized as a person with strengths and challenges in everyday life, (2) collaborative relationships between students and teachers, (3) flexible boundaries in the relationship between teachers and students and (4) organization of classes and procedures set the stage for TSR. Collaborative, emotional and contextual qualities were found important to the development of TSR in upper secondary school. Experiences of negative qualities of TSR can contribute to push students out of school. Teachers and helpers experience that TSR may have the potential to play a role in promoting mental health in students' everyday life. PMID- 27707450 TI - Effects of Yoga and Aerobic Exercise on Actigraphic Sleep Parameters in Menopausal Women with Hot Flashes. AB - STUDY OBJECTIVES: To determine effects of yoga and aerobic exercise compared with usual activity on objective assessments of sleep in midlife women. METHODS: Secondary analyses of a randomized controlled trial in the Menopause Strategies: Finding Lasting Answers for Symptoms and Health (MsFLASH) network conducted among 186 late transition and postmenopausal women aged 40-62 y with hot flashes. Women were randomized to 12 w of yoga, supervised aerobic exercise, or usual activity. The mean and coefficient of variation (CV) of change in actigraph sleep measures from each intervention group were compared to the usual activity group using linear regression models. RESULTS: Baseline values of the primary sleep measures for the entire sample were mean total sleep time (TST) = 407.5 +/- 56.7 min; mean wake after sleep onset (WASO) = 54.6 +/- 21.8 min; mean CV for WASO = 37.7 +/- 18.7 and mean CV for number of long awakenings > 5 min = 81.5 +/- 46.9. Changes in the actigraphic sleep outcomes from baseline to weeks 11-12 were small, and none differed between groups. In an exploratory analysis, women with baseline Pittsburgh Sleep Quality Index higher than 8 had significantly reduced TST-CV following yoga compared with usual activity. CONCLUSIONS: This study adds to the currently scant literature on objective sleep outcomes from yoga and aerobic exercise interventions for this population. Although small effects on self reported sleep quality were previously reported, the interventions had no statistically significant effects on actigraph measures, except for potentially improved sleep stability with yoga in women with poor self-reported sleep quality. PMID- 27707452 TI - Female genital mutilation: a systematic review of research on its economic and social impacts across four decades. AB - BACKGROUND: Global efforts to end female genital mutilation (FGM) have intensified in recent decades because of the rising awareness that such a practice is an act of extreme violence against women and girls. Articles on FGM have been published highlighting the combined efforts of international and non governmental organizations, governments, as well as religious and civil society groups to end the practice. However, the consequences of this research are not well known, and it seems that the socioeconomic aspects of the practice are underreported. OBJECTIVE: This review aims to characterize over a 40-year period the scientific output on the consequences of FGM in African countries, the most affected region known for the high prevalence of FGM, and review data on the socioeconomic consequences of the practice. DESIGN: A systematic review of literature was done, looking at the following databases: PubMed, Embase, CINAHL, BDSP, Web of Science, PsycINFO, FRANCIS, Sociological Abstracts, WHOLIS, RERO, and SAPHIR. The analysis was limited to articles concerning the African continent, published in English and French, from January 1, 1972, to December 31, 2011. RESULTS: One hundred ninety-eight articles were reviewed. More than half of the articles were published during the last decade of the study period. The majority of papers were published in biomedical journals (64.1%). Most studies looked at Africa as a region (33.3%). Nigeria was the single country most investigated (19.2%), followed by Egypt (10.6%). Most first authors were affiliated to non-African countries (60.6%): among them 21.2% were US-based, 4% were from African institutions, and 16.2% from Nigeria.The medical and psychological consequences (51.5%) and the prevalence and ethics of the practice (34.4%) were the most frequently investigated topics. The socioeconomic consequences were addressed in a minority of the papers (14.1%): they were classified into direct economic consequences (2.5%), school attendance (1%), marriageability (2%), sexual and marital consequences (3.5%), fertility (2.5%), domestic violence (1%), and discrimination (1.5%). CONCLUSIONS: The publication of articles on the consequences of FGM is increasing, but there is little research on the socioeconomic consequences of the practice. More scientific data focusing on this dimension is necessary to strengthen prevention, advocacy, and intervention campaigns.

AB - BACKGROUND: Low-density lipoprotein (LDL) oxidation is a risk factor for atherosclerosis. Lycopene and tomato-based products have been described as potent inhibitors of LDL oxidation. OBJECTIVES: To evaluate the effect of a 2-week supplementation with a carotenoid-rich tomato extract (CRTE) standardized for a 1:1 ratio of lycopene and phytosterols, on post-prandial LDL oxidation after a high-fat meal. DESIGN: In a randomized, double-blind, parallel-groups, placebo controlled study, 146 healthy normal weight individuals were randomly assigned to a daily dose of CRTE standardized for tomato phytonutrients or placebo during 2 weeks. Oxidized LDL (OxLDL), glucose, insulin, and triglyceride (TG) responses were measured for 8 h after ingestion of a high-fat meal before and at the end of intervention. RESULTS: Plasma lycopene, phytofluene, and phytoene were increased throughout the study period in the CRTE group compared to placebo. CRTE ingestion significantly improved changes in OxLDL response to high-fat meal compared to placebo after 2 weeks (p<0.0001). Changes observed in glucose, insulin, and TG responses were not statistically significant after 2 weeks of supplementation, although together they may suggest a trend of favorable effect on metabolic outcomes after a high-fat meal. CONCLUSIONS: Two-week supplementation with CRTE increased carotenoids levels in plasma and improved oxidized LDL response to a high-fat meal in healthy normal weight individuals. PMID- 27707454 TI - Yellow fever vaccine-associated neurotropic disease (YEL-AND) - A case report. AB - Yellow fever (YF) is a mosquito-borne viral hemorrhagic fever, which is a serious and potentially fatal disease with no specific antiviral treatment that can be effectively prevented by an attenuated vaccine (YEL). Despite the long history of safe and efficacious YF vaccination, sporadic case reports of serious adverse events (SAEs) have been reported, including yellow fever vaccine-associated neurotropic disease (YEL-AND). YEL-AND usually appears within one month of YF vaccination, manifesting as meningoencephalitis, Guillain-Barre syndrome (GBS) or acute disseminated encephalomyelitis (ADEM). We report a case of YEL-AND with meningitis presentation in a 39-year-old Caucasian man without evidence of significant risk factors, which was confirmed by the presence of the YF virus and specific immunoglobulin G (IgG) antibodies in the cerebrospinal fluid (CSF). In conclusion, we should stress the importance of balancing the risk of SAEs associated with the vaccine and the benefits of YF vaccination for each patient individually.

AB - The high prevalence of smoking in people with serious mental illness contributes substantially to the disproportionately high morbidity and premature mortality in this population. There is an urgent need to help people with serious mental illness to quit smoking. We discuss competing explanations for the high prevalence of smoking in people with serious mental illness and the effectiveness of available smoking cessation interventions. We propose trials of harm reduction options, such as nicotine replacement therapy and electronic cigarettes (e cigarettes), as long-term substitutes for cigarettes in smokers with serious mental illness who are unable to quit smoking. We also propose that smoke-free psychiatric units provide smoking cessation support on patient admission to the hospital and after discharge.

AB - Squids are active and opportunistic predators that feed on a wide range of prey. Their active movements in the water column and their voracity promote a high consumption of food. In the pelagic environment off Ecuador, marine pollution is characterized by plastic debris with a mainland origin, including plastics trash of fishing gears. The objective of this work was to describe the presence of plastic remains in the stomach contents of Dosidicus gigas caught off the coast of Ecuador. Results demonstrated that 12% of the stomachs contained plastic remains. These plastics were identified as multifilament of polyethylene lines and polyvinyl chloride remains. Findings of this work could be related to an increase in the discharge of solid materials in the water column, increasing the probability to be ingested by the jumbo squid. PMID- 27707468 TI - Does Sudden Unexplained Nocturnal Death Syndrome Remain the Autopsy-Negative Disorder: A Gross, Microscopic, and Molecular Autopsy Investigation in Southern China. AB - OBJECTIVE: To look for previously unrecognized cardiac structural abnormalities and address the genetic cause for sudden unexplained nocturnal death syndrome (SUNDS). METHODS: Data for 148 SUNDS victims and 444 controls (matched 1:3 on sex, race, and age of death within 1 year) were collected from Sun Yat-sen University from January 1, 1998, to December 31, 2014, to search morphological changes. An additional 17 patients with Brugada syndrome (BrS) collected from January 1, 2006, to December 31, 2014, served as a comparative disease cohort. Target-captured next-generation sequencing for 80 genes associated with arrhythmia/cardiomyopathy was performed in 44 SUNDS victims and 17 patients with BrS to characterize the molecular spectrum. RESULTS: The SUNDS victims had slight but statistically significant increased heart weight and valve circumference compared with controls. Twelve of 44 SUNDS victims (SCN5A, SCN1B, CACNB2, CACNA1C, AKAP9, KCNQ1, KCNH2, KCNJ5, GATA4, NUP155, ABCC9) and 6 of 17 patients with BrS (SCN5A, CACNA1C; P>.05) carried rare variants in primary arrhythmia susceptibility genes. Only 2 of 44 SUNDS cases compared with 5 of 17 patients with BrS hosted a rare variant in the most common BrS-causing gene, SCN5A (P=.01). Using the strict American College of Medical Genetics guideline-based definition, it was found that only 2 of 44 (KCNQ1) SUNDS and 3 of 17 (SCN5A) patients with BrS hosted a "(likely) pathogenic" variant. Fourteen of 44 SUNDS cases with cardiomyopathy-related variants had a subtle but significantly decreased circumference of cardiac valves, and tended to die on average 5 to 6 years younger compared with the remaining 30 cases (P=.02). CONCLUSION: We present the first comprehensive autopsy evidence that SUNDS victims may have concealed cardiac morphological changes. SUNDS and BrS may result from different molecular pathological underpinnings. The distinct association between cardiomyopathy-related rare variants and SUNDS warrants further investigation. PMID- 27707470 TI - Sustainability and the Spanish port system. Analysis of the relationship between economic and environmental indicators. AB - Research into the methodological development of alternative systems of sustainability measures is recent. In understanding sustainable development in a multi-dimensional sense, one of the most significant advances was the construction of Synthetic Indexes, applicable to different spatial spheres or to organisations, businesses, institutions, etc. The Spanish port system of general interest comprises 46 ports integrated in 28 Port Authorities, which in 2014 moved 482,000,000t of goods and more than 28 million passengers. This gives an idea of its importance for the Spanish economy. Using a derivation of the procedure used to calculate the Port Sustainability Synthetic Index, in this research the analysis of the relationship that exists between the findings obtained for the economic and environmental dimensions is used. This enables the existence of links between ports and economic and environmental indicators for a sample of 16 Port Authorities of Spain to be verified. PMID- 27707471 TI - Concentration and congener pattern of polychlorinated biphenyls in blubber and liver of Hubbs' beaked whale (Mesoplodon carlhubbsi), using a sulfoxide and an Ag ION solid phase extraction cartridge as a simplified cleanup technique for biological samples. AB - We performed the first known study of polychlorinated biphenyls (PCBs) concentrations and patterns in the blubber and liver of a Hubbs' beaked whale. Samples were pretreated with SupelcleanTM sulfoxide and Discovery(r) Ag-ION solid phase extraction cartridges to remove whale oil. PCB concentrations in the blubber and liver were 13,000 and 7300ng/g lipid, respectively. Highly poisonous congeners such as dioxin-like (DL) PCBs tended to accumulate in the liver. The toxic equivalents (TEQ) of DL-PCBs in the liver (740pg-TEQ/g lipid) were higher than those in the blubber (74pg-TEQ/g lipid). The blubber and liver samples showed that hexachlorinated biphenyls were dominant among homologues, and PCB-153 was dominant among congeners. Several congeners accumulated disproportionately in the blubber and the liver (PCB-28, 52, 74, 99, and 118), while others did not persist (PCB-31, 70, and 110). This indicates that PCBs are metabolized differently according to their specific composition. PMID- 27707472 TI - The impact of wastewater treatment effluent on microbial biomasses and diversities in coastal sediment microcosms of Hangzhou Bay. AB - Disposal of wastewater treatment plant (WWTP) effluent into sea, a typical anthropogenic disturbance, may influence many environmental factors and change the coastal microbial community structure. In this study, by setting up coastal sediment microcosms perturbed by WWTP effluent, the changes of microbial community structure under different degree of disturbances were investigated. Quantitative PCR (qPCR) and terminal restriction fragment length polymorphism (T RFLP) were used to analyzed the biomass and biodiversity. High throughput sequencing analysis was used to identify the classification of the microorganisms. Our study suggested that low ratio of WWTP effluent may stimulate dominant species, which increase the biomass but decrease the biodiversity; while high ratio of WWTP effluent may depress all species, which decrease the biomass but increase the biodiversity. In other words, the impact was dose-dependent. The changes of microbial community structure may provide a metric for water environmental assessment and pollution control.

PMID- 27707496 TI - Early, goal-directed mobilisation in the surgical intensive care unit: a randomised controlled trial. AB - BACKGROUND: Immobilisation predicts adverse outcomes in patients in the surgical intensive care unit (SICU). Attempts to mobilise critically ill patients early after surgery are frequently restricted, but we tested whether early mobilisation leads to improved mobility, decreased SICU length of stay, and increased functional independence of patients at hospital discharge. METHODS: We did a multicentre, international, parallel-group, assessor-blinded, randomised controlled trial in SICUs of five university hospitals in Austria (n=1), Germany (n=1), and the USA (n=3). Eligible patients (aged 18 years or older, who had been mechanically ventilated for <48 h, and were expected to require mechanical ventilation for >=24 h) were randomly assigned (1:1) by use of a stratified block randomisation via restricted web platform to standard of care (control) or early, goal-directed mobilisation using an inter-professional approach of closed-loop communication and the SICU optimal mobilisation score (SOMS) algorithm (intervention), which describes patients' mobilisation capacity on a numerical rating scale ranging from 0 (no mobilisation) to 4 (ambulation). We had three main outcomes hierarchically tested in a prespecified order: the mean SOMS level patients achieved during their SICU stay (primary outcome), and patient's length of stay on SICU and the mini-modified functional independence measure score (mmFIM) at hospital discharge (both secondary outcomes). This trial is registered with ClinicalTrials.gov (NCT01363102). FINDINGS: Between July 1, 2011, and Nov 4, 2015, we randomly assigned 200 patients to receive standard treatment (control; n=96) or intervention (n=104). Intention-to-treat analysis showed that the intervention improved the mobilisation level (mean achieved SOMS 2.2 [SD 1.0] in intervention group vs 1.5 [0.8] in control group, p<0.0001), decreased SICU length of stay (mean 7 days [SD 5-12] in intervention group vs 10 days [6-15] in control group, p=0.0054), and improved functional mobility at hospital discharge (mmFIM score 8 [4-8] in intervention group vs 5 [2-8] in control group, p=0.0002). More adverse events were reported in the intervention group (25 cases [2.8%]) than in the control group (ten cases [0.8%]); no serious adverse events were observed. Before hospital discharge 25 patients died (17 [16%] in the intervention group, eight [8%] in the control group). 3 months after hospital discharge 36 patients died (21 [22%] in the intervention group, 15 [17%] in the control group). INTERPRETATION: Early, goal-directed mobilisation improved patient mobilisation throughout SICU admission, shortened patient length of stay in the SICU, and improved patients' functional mobility at hospital discharge.

AB - BACKGROUND: Primary angle-closure glaucoma is a leading cause of irreversible blindness worldwide. In early-stage disease, intraocular pressure is raised without visual loss. Because the crystalline lens has a major mechanistic role, lens extraction might be a useful initial treatment. METHODS: From Jan 8, 2009, to Dec 28, 2011, we enrolled patients from 30 hospital eye services in five countries. Randomisation was done by a web-based application. Patients were assigned to undergo clear-lens extraction or receive standard care with laser peripheral iridotomy and topical medical treatment. Eligible patients were aged 50 years or older, did not have cataracts, and had newly diagnosed primary angle closure with intraocular pressure 30 mm Hg or greater or primary angle-closure glaucoma. The co-primary endpoints were patient-reported health status, intraocular pressure, and incremental cost-effectiveness ratio per quality adjusted life-year gained 36 months after treatment. Analysis was by intention to treat. This study is registered, number ISRCTN44464607. FINDINGS: Of 419 participants enrolled, 155 had primary angle closure and 263 primary angle closure glaucoma. 208 were assigned to clear-lens extraction and 211 to standard care, of whom 351 (84%) had complete data on health status and 366 (87%) on intraocular pressure. The mean health status score (0.87 [SD 0.12]), assessed with the European Quality of Life-5 Dimensions questionnaire, was 0.052 higher (95% CI 0.015-0.088, p=0.005) and mean intraocular pressure (16.6 [SD 3.5] mm Hg) 1.18 mm Hg lower (95% CI -1.99 to -0.38, p=0.004) after clear-lens extraction than after standard care. The incremental cost-effectiveness ratio was L14 284 for initial lens extraction versus standard care. Irreversible loss of vision occurred in one participant who underwent clear-lens extraction and three who received standard care. No patients had serious adverse events. INTERPRETATION: Clear-lens extraction showed greater efficacy and was more cost-effective than laser peripheral iridotomy, and should be considered as an option for first-line treatment.

AB - Major burns provoke a profound stress response, which is unrivalled in terms of its magnitude and duration. Evidence suggests that the pathophysiological stress response to severe burn trauma persists for several years after injury. Thus, there is a pressing need for novel strategies that mitigate this response and restore normal metabolic function in patients with burns. This is the first in a Series of three papers about the care of people with burns. In this paper, we review the current knowledge of the stress response to burn trauma, with a focus on hypermetabolism, muscle wasting, and stress-induced diabetes. We highlight recent developments and important knowledge gaps that need to be pursued to develop novel therapeutic strategies to improve outcomes in burn survivors. PMID- 27707501 TI - The race to become the next UN Secretary-General. PMID- 27707499 TI - Hypertrophic scarring: the greatest unmet challenge after burn injury. AB - Improvements in acute burn care have enabled patients to survive massive burns that would have once been fatal. Now up to 70% of patients develop hypertrophic scars after burns. The functional and psychosocial sequelae remain a major rehabilitative challenge, decreasing quality of life and delaying reintegration into society. Approaches to optimise healing potential of burn wounds use targeted wound care and surgery to minimise the development of hypertrophic scarring. Such approaches often fail, and modulation of the established scar is continued although the optimal indication, timing, and combination of therapies have yet to be established. The need for novel treatments is paramount, and future efforts to improve outcomes and quality of life should include optimisation of wound healing to attenuate or prevent hypertrophic scarring, well designed trials to confirm treatment efficacy, and further elucidation of molecular mechanisms to allow development of new preventive and therapeutic strategies. PMID- 27707502 TI - Leucite and cooling rate effect on porcelain-zirconia mechanical behavior. AB - OBJECTIVE: This study investigated the influence of the cooling protocol on the mechanical behavior of Y-TZP veneered with porcelain with different compositions. The tested hypotheses were: (1) Y-TZP infrastructures veneered with porcelain containing leucite in its composition presents higher flexural strength (sigma) and reliability (m), and (2) slow cooling protocol results in greater sigma and m. METHODS: A total of 120 bilayer porcelain-Y-TZP bar-shaped specimens were prepared with the dimensions of 1.8mm (0.8mm Y-TZP+/-1.0mm porcelain)*4.0mm*16.0mm. Specimens were divided into four groups (n=30) according to the porcelain composition (containing or not leucite) and cooling protocol. Fast cooling was performed by opening the furnace chamber at sintering temperature. For the slow cooling, the chamber was maintained closed until it reached the room temperature. Specimens were tested in three-point bending with the porcelain surface under tension using a universal testing machine, in 37 degrees C water, at 0.5mm/min crosshead speed. Data were analyzed by two-way ANOVA, Tukey post-hoc test (alpha=0.05) and Weibull. RESULTS: Y-TZP veneered with porcelains with different microstructural composition presented similar sigma and m values (p=0.718). The cooling protocol had no influence on the sigma and m values of the experimental groups (p=0.718). Cracking represented 95% of failures, whereas the initial flaw propagated from the porcelain surface towards the interface. SIGNIFICANCE: Y-TZP veneered with porcelain containing or not leucite present similar mechanical behavior and, at 1-mm thickness, is not sensitive to the cooling protocol. PMID- 27707503 TI - Reducing the effect of polymerization shrinkage of temporary fixed dental prostheses by using different materials and fabrication techniques. AB - OBJECTIVE: The aim of this laboratory study was to evaluate the horizontal and vertical effects of the polymerization shrinkage of three-unit temporary fixed dental prostheses (FDPs) on the position of the prepared teeth. In addition, the reduction of these effects by using different fabrication techniques was evaluated. METHODS: A total of 192 temporary FDPs were fabricated using one methacrylate (MA) and two dimethacrylate (DMA) materials. Each material group (n=64) was divided into two groups according to the fabrication methods (M1: curing on the prepared teeth, M2: curing in a silicone mold). Each fabrication group was divided into four subgroups (n=8) according to the relining method used (B: no relining, S: spacer foil 300MUm, DG: grinding-out with 500MUm cutting depth, and FG: free grinding). The experimental apparatus consisted of two abutment teeth lowered at right angles into a silicone mold. One prepared tooth was embedded in silicone to simulate the periodontium and permit slight horizontal tooth movement. The dimensional changes were recorded with an optical microscope. The test images were superimposed and measured using image analysis software. RESULTS: The statistical analysis showed that there were significantly higher horizontal changes for the MA than the DMA resins in M1, while there was none in M2. Regarding the vertical changes, there were significant differences between the baseline group and all relining and fabrication groups in all materials. SIGNIFICANCE: Relining of directly fabricated temporary FDPs significantly reduces the effect of polymerization shrinkage and thus secures the position of the prepared teeth. PMID- 27707500 TI - Pathophysiology, research challenges, and clinical management of smoke inhalation injury. AB - Smoke inhalation injury is a serious medical problem that increases morbidity and mortality after severe burns. However, relatively little attention has been paid to this devastating condition, and the bulk of research is limited to preclinical basic science studies. Moreover, no worldwide consensus criteria exist for its diagnosis, severity grading, and prognosis. Therapeutic approaches are highly variable depending on the country and burn centre or hospital. In this Series paper, we discuss understanding of the pathophysiology of smoke inhalation injury, the best evidence-based treatments, and challenges and future directions in diagnostics and management.

AB - BACKGROUND AND PURPOSE: The aim of this study is to derive "dose painting by numbers" prescriptions from retrospectively observed recurrence volumes in a patient group treated with conventional radiotherapy for head and neck squamous cell carcinoma. MATERIALS AND METHODS: The spatial relation between retrospectively observed recurrence volumes and pre-treatment standardized uptake values (SUV) from fluorodeoxyglucose positron emission tomography (FDG-PET) imaging was determined. Based on this information we derived SUV driven dose response functions and used these to optimize ideal dose redistributions under the constraint of equal average dose to the tumor volumes as for a conventional treatment. The response functions were also implemented into a treatment planning system for realistic dose optimization. RESULTS: The calculated tumor control probabilities (TCP) increased between 0.1-14.6% by the ideal dose redistributions for all included patients, where patients with larger and more heterogeneous tumors got greater increases than smaller and more homogeneous tumors. CONCLUSIONS: Dose painting prescriptions can be derived from retrospectively observed recurrence volumes spatial relation to pre-treatment FDG-PET image data. The ideal dose redistributions could significantly increase the TCP for patients with large tumor volumes and large spread in SUV from FDG-PET. The results yield a basis for prospective studies to determine the clinical value for dose painting of head and neck squamous cell carcinomas. PMID- 27707506 TI - Fast interaction between AMPA and NMDA receptors by intracellular calcium. AB - Suppression of NMDA receptor (NMDAR)-mediated currents by intracellular Ca2+ has been described as a negative feedback loop in NMDAR modulation. In the time scale of tenths of milliseconds the depth of the suppression does not depend on the Ca2+ source. It may be caused by Ca2+ influx through voltage-gated calcium channels, NMDAR channels or release from intracellular stores. However, NMDARs are often co-expressed in synapses with Ca2+-permeable AMPA receptors (AMPARs). Due to significant differences in activation kinetics between these two types of glutamate receptors (GluRs), Ca2+ entry through AMPARs precedes full activation of NMDARs, and therefore, might have an impact on the amplitude of NMDAR-mediated currents. The study of Ca2+-mediated crosstalk between AMPAR and NMDAR in native synapses is challenging due to high NMDAR Ca2+ permeability. Therefore, recombinant Ca2+-permeable AMPAR and Ca2+-impermeable NMDAR mutant channels were co-expressed in HEK 293 cells to examine their interaction. An AMPAR-mediated increase in intracellular Ca2+ concentration ([Ca2+]i) reversibly reduced the size of NMDAR-mediated whole-cell currents. The time course of the NMDAR channel inactivation and recovery from inactivation followed the time course of the [Ca2+]i transient. When brief (1ms) pulses of glutamate were applied to outside out patches, the degree of NMDAR inactivation increased with the increase in charge carried by the currents through co-activated AMPARs. However, AMPAR mediated NMDAR inactivation was abolished in the presence of intracellular fast Ca2+ buffer BAPTA or in Ca2+-free extracellular solution. We conclude that Ca2+ entering through AMPARs inactivates co-localized NMDARs in the time range of excitatory postsynaptic currents. PMID- 27707507 TI - Rift Valley fever trasmission dynamics described by compartmental models. AB - Rift Valley fever (RVF) is one of the most important zoonotic Transboundary Animal Diseases able to cross international borders and cause devastating effect on animal health and food security. Climate changes and the presence of competent vectors in the most of the current RVF-free temperate countries strongly support the inclusion of RVF virus (RVFV) among the most significant emerging viral threats for public and animal health. The transmission of RVFV is driven by complex eco-climatic factors making the epidemiology of RVF infection difficult to study and to understand. Mathematical, statistical and spatial models are often used to explain the mechanisms underlying these biological processes, providing new and effective tools to plan measures for public health protection. In this paper we performed a systematic literature review on RVF published papers with the aim of identifying and describing the most recent papers developing compartmental models for the study of RVFV transmission dynamics. PMID- 27707508 TI - Tracing the use of evaluations in legislative processes in Swiss cantonal parliaments. AB - Several studies have challenged the notion that members of parliament use information from evaluations to make policies. However, it is also argued that the function of evaluations in an inherently political context such as parliament is to provide arguments and justifications rather than simply supply information for policymaking. This paper provides a fine-grained account of the use of evaluations by members of parliament in the context of political conflict. Previous research has highlighted the importance of this factor, but the findings are controversial. Here, four case studies of policy processes in two Swiss cantonal parliaments illustrate that political conflict is highly context specific. Documentary analysis and interviews show that the members of parliament used evaluations to inform themselves as well as to gain political support in the moderately contested case. This both supports and challenges previous research. Comparing the cases reveals that the administration's use of evaluations strongly influences their use in the non-professional cantonal parliaments. However, Switzerland's semi-direct democracy and its conflict-resolving mechanisms shape and limit this role, particularly if political conflict is high. PMID- 27707509 TI - Comparative Pharmacokinetic Analysis of Thiamine and Its Phosphorylated Metabolites Administered as Multivitamin Preparations. AB - PURPOSE: Fursultiamine and benfotiamine are lipophilic thiamine derivatives used as oral sources of thiamine. Although there are many publications on the pharmacokinetic (PK) properties of thiamine-containing products, no direct comparisons between these agents . We aimed to compare the PK profiles of these lipophilic thiamine derivatives and to compare the extent of the increase in bioavailability to that of naive thiamine. METHODS: Two randomized, single-dose, 2-way crossover, full PK studies were conducted in healthy Korean male subjects (n = 24 per group). Among the test compounds, fursultiamine was compared with benfotiamine (reference A in study A) and thiamine nitrate (reference B in study B). All formulations were multivitamin preparations containing the test or reference formulation as the major thiamine source. In study A, the plasma and hemolysate concentrations of thiamine and its metabolites were measured, while only the plasma thiamine concentration was assayed in study B. FINDINGS: The systemic thiamine exposure of the test compound was slightly greater than that of reference A, based on the geometric mean ratio (%) of the AUClast value for plasma (116.6%) and hemolysate (137.5%). The thiamine diphosphate (TDP) distribution between plasma and hemolysate showed clear differences according to the formulations, in that more TDP was present in the hemolysate when thiamine was given as the test formulation. The AUClast value of plasma thiamine showed a >300% increase when thiamine was given as the test formulation in study B. The summed total exposure to thiamine (thiamine + TDP in both plasma and hemolysate) observed as a point estimate after the administration of fursultiamine was slightly greater than that with benfotiamine; however, the 90% CI was within the conventional bioequivalence range. IMPLICATIONS: These findings support clear benefits of lipophilic thiamine derivatives in the absorption of thiamine in healthy volunteers.

The time to placement was measured from advancement of the pulmonary artery catheter in the superior vena cava (20 cm) to a final location at the junction of the right pulmonary artery and main pulmonary artery. All 20 pulmonary artery catheters were placed successfully using transesophageal echocardiography guidance and the median time to placement was 43 seconds. In 9 of the 20 patients (45%), the catheter was placed successfully on the first attempt without any adjustments. However, in 9 others (45%), the catheter required manipulation under transesophageal echocardiography vision. In 3 patients (15%), the pulmonary artery catheter was observed to be coiled in the right atrium and in 1 instance (5%) manipulation of the catheter in the right ventricle was required to enter the outflow tract. CONCLUSIONS: Transesophageal echocardiography is a viable adjunctive method to conventional pressure waveform placement of pulmonary artery catheters in potentially difficult patients. PMID- 27707513 TI - B-1 cell decreases susceptibility to encephalitozoonosis in mice. AB - Encephalitozoon cuniculi is an opportunist intracellular pathogen of mammals. The adaptive immune response is essential to eliminate E. cuniculi, but evidence is mounting that the response initiated by the innate immune response may ultimately define whether or not the parasite can survive. B-1 cells may act as antigen presenting cells or differentiate into phagocytes, playing different roles in many infection models. However, the role of these cells in the dynamics of Encephalitozoon sp. infections is still unknown. To investigate the role of B-1 cells in E. cuniculi infection, BALB/c and BALB/c XID (B-1 cells deficient) mice were infected with E. cuniculi spores. Cytometric analyses of peritoneal cells showed that B-1 cells and macrophages increased significantly in infected BALB/c mice compared to uninfected controls. Despite the increase in the number of CD4+ and CD8+ lymphocytes in XID mice, these animals were more susceptible to infection as evidenced histologically with more prominent inflammatory lesions and parasite burden. Pro-inflammatory cytokines increased in both infected BALB/c and BALB/c XID mice. To confirm B-1 cells role in encephalitozoonosis, we adoptively transferred B-1 cells to BALB/c XID mice and this group showed few symptoms and microscopic lesions, associated with an increased in cytokines. Together, these results suggest that B-1 cells may increase the resistance of BALB/c mice to encephalitozoonosis, evidencing for the first time the important role of B-1 lymphocytes in the control of microsporidia infection. PMID- 27707514 TI - Non-redundant role of the chemokine receptor CX3CR1 in the anti-inflammatory function of gut macrophages. AB - Mucosal immunity at the intestinal level is constantly challenged by the presence of external food and microbial antigens and must be kept under strict control to avoid the rise of aberrant inflammation. Among cells of the innate immunity, macrophages expressing the chemokine receptor CX3CR1 are strategically located near the gut epithelial barrier. These cells contribute to the maintenance of homeostasis by producing the anti-inflammatory cytokine IL-10; however, their role in the control of full blown inflammation and tissue injury is controversial. In this study we investigated mice proficient or deficient for the expression of the CX3CR1 receptor in a model of dextran sulphate sodium (DSS) induced acute colitis. We found that KO mice (CX3CR1GFP/GFP) had a more severe disease compared to WT mice (CX3CR1GFP/+), both in terms of histological examination of colonic tissues and leukocyte infiltration, with an expansion of macrophages and CD4-Th17 lymphocytes. The expression of several inflammatory mediators (IL-1beta, IL-6, IFNgamma, iNOS) was also significantly upregulated in KO mice, despite higher IL-10 production. Overall, our study demonstrates that macrophages expressing a functional CX3CR1 receptor have an important and non redundant role in controlling the abnormal intestinal inflammation that may lead to tissue damage.

AB - PURPOSE: Lesbian, gay, bisexual, and transgender (LGBT) adolescents are at greater risk for mental health problems than their heterosexual peers, in part due to victimization. Social support, particularly from families, has been identified as an important promotive factor. However, little is known about how LGBT youth experience multiple forms of support or how early support predicts mental health across adolescence and into young adulthood. METHODS: In an analytic sample of 232 LGBT youth aged 16-20 years at baseline across 5.5 years, we compared developmental trajectories of psychological distress between three empirically derived social support cluster types at baseline: those who reported uniformly low support, those who reported uniformly high support, and those who reported nonfamily support (i.e., high peer and significant other but low family support). RESULTS: Longitudinal multilevel modeling, controlling for age, victimization, and social support at each wave, indicated key differences between cluster types. Youth in the low and nonfamily support clusters reported greater distress across all time points relative to youth in the high support cluster; however, they also showed a sharper decline in distress. Youth in the nonfamily cluster gained family support across adolescence, such that they resembled youth in the high support cluster by early adulthood. CONCLUSIONS: Findings underscore the importance of family support for LGBT youth. Youth who lack family support, but who have other forms of support, report a decrease in psychological distress and an increase in family support across adolescence. Youth who are low in all forms of support continue to exhibit high distress.

AB - PURPOSE: Use of other tobacco products (smokeless tobacco, hookah, cigarillo, and e-cigarettes) is increasing, particularly among young adults, and there are few regulations on marketing for these products. We examined the associations between tobacco marketing receptivity and other tobacco product (OTP) use among young adult bar patrons (aged 18-26 years). METHODS: Time-location sampling was used to collect cross-sectional surveys from 7,540 young adult bar patrons from January 2012 through March of 2014. Multivariable logistic regression analyses in 2015 examined if tobacco marketing receptivity was associated (1) with current (past 30 day) OTP use controlling for demographic factors and (2) with dual/poly use among current cigarette smokers (n = 3,045), controlling for demographics and nicotine dependence. RESULTS: Among the entire sample of young adult bar patrons (Meanage = 23.7, standard deviation = 1.8; 48.1% female), marketing receptivity was consistently associated with current use of all OTP including smokeless tobacco (adjusted odds ratio [AOR]= 2.56, 95% confidence interval [CI] 2.08-3.16, p < .001), hookah (AOR = 1.97, 95% CI 1.58-2.43, p < .001), cigarillos (AOR = 3.00, 95% CI 2.21-4.08, p < .001), electronic cigarettes (AOR = 2.43, 95% CI 1.93 3.04, p < .001), and multiple tobacco products (AOR = 2.93, 95% CI 2.45-3.51, p < .001). Among current smokers, marketing receptivity was significantly associated with use of smokeless tobacco (AOR = 1.63, 95% CI 1.22-2.18, p < .01), cigarillos (AOR = 1.81, 95% CI 1.22-2.70, p < .01), and multiple tobacco products (AOR = 1.58, 95% CI 1.27-1.97, p < .001). CONCLUSIONS: OTP use is common among young adult bar patrons, and it is associated with tobacco marketing receptivity. Efforts to limit tobacco marketing should address OTP in addition to cigarettes.

PMID- 27707518 TI - [Care costs and activity in the last three months of life of cancer patients who died in the Basque Country (Spain)]. AB - OBJECTIVE: To analyse the use of health resources and its budget in the last months of life of the population who died from malignant neoplasm in the Basque Autonomous Country (Spain). METHOD: Retrospective observational study of a population with a diagnosis of malignancy deceased in the Basque Country (2010 and 2011). DATA SOURCE: MDS and Mortality Register. VARIABLES: gender, age, place of death, tumour location, clinical activity data and costs in the last three months of life. We performed a descriptive analysis of clinical activity and costs, and lineal multivariate regressions to obtain the adjusted mean costs by gender, age and place of death. RESULTS: 9,333 deaths from malignancy were identified in 2010 and 2011. 65.4% were men, 61.5% aged 70 or over, mean age 72.9 years, 71.1% died in hospital. People who died in the hospital had an average cost of about double that of the people who died at home (?14,794 and ?7,491, respectively; p <0.001) and 31.3% higher than in the nursing home (?11,269; p <0.001). CONCLUSIONS: Greater interventions at the end of life at the community level are necessary, strengthening the care capacity of primary health care, both from training and support from expert teams in order to change the current care profile to a more outpatient care that allows a lower consumption of resources and greater care at home. PMID- 27707520 TI - Molecular characterization of methoprene-tolerant gene (Met) in the swimming crab Portunus trituberculatus: Its putative role in methyl farnesoate-mediated vitellogenin transcriptional activation. AB - Methoprene-tolerant (Met) belongs to the basic helix-loop-helix (bHLH)-Per-Arnt Sim (PAS) family of nuclear transcriptional regulators, and is the leading candidate receptor for the insect Juvenile hormone (JH) and the crustacean methyl farnesoate (MF). In the present study, a full-length cDNA of Met was cloned from the swimming crab, Portunus trituberculatus (PtMet). The PtMet amino acid sequence was found to contain domains characteristic of the bHLH-PAS family proteins and to have several conserved amino acid residues specifically responsible for JH or MF binding. In addition to its extensive tissue expression, PtMet mRNA is highly expressed in the female hepatopancreas, the primary site of vitellogenin (Vg) synthesis in P. trituberculatus. PtMet expression was significantly increased in the early-vitellogenic stage of ovarian development, which indicated that likely involvement in vitellogenesis regulation. In vitro, MF induced up-regulation of PtMet and PtVg expression in the hepatopancreas, but not in the ovary. In vivo, MF induced PtMet and PtVg expression in the hepatopancreas,and only PtMet expression was induced in the ovary. Taken together, these results suggest that Met can potentially serve as a MF receptor in crustaceans. In addition, the binding of Met to MF might transcriptionally regulate Vg synthesis in the hepatopancreas. PMID- 27707521 TI - Use of heterospermic inseminations and paternity testing to evaluate the relative contributions of common sperm traits and seminal plasma proteins in boar fertility. AB - The objective of this study was to evaluate relationships between common semen quality estimates including sperm motility, sperm morphology, spontaneous capacitation status and seminal plasma proteins and boar fertility using heterospermic inseminations and subsequent paternity testing. All boars (n=12) used in the study had excellent semen quality (>=70% normal sperm) that resulted in average farrowing rates and litter sizes of 88.9+/-0.7% and 11.7+/-0.1 pigs, respectively. Their ejaculates were combined to make heterospermic insemination doses in such a way that each boar was tested against all of his contemporaries. The proportion of piglets sired by each individual was used to separate boars into three fertility groups: High (71.6+/-4.8%; n=3); Medium (51.6+/-3.8%; n=6); and Low (25.2%+/-5.3%; n=3). Ejaculates from High fertility boars had more motile sperm with normal acrosomes that moved faster in a straight-line and were more likely to undergo an acrosome reaction (p<=0.05) compared with their counterparts in the Low fertility group. Ejaculates from High fertility boars contained the greatest concentrations of three seminal plasma proteins (25.9kD/5.9pI; 55.1kD/4.8pI; and 70.1kD/5.2pI; p<=0.05), whereas concentrations of a 19.1kD/6.8pI were highest in semen from Low fertility boars (p<=0.05). Multiple regression analyses indicated that concentrations of the 25.9kD/5.9pI seminal plasma protein explained 66% of the variation observed in the proportion of pigs sired within a litter among boars (p<=0.00001). These results demonstrate that heterospermic inseminations and subsequent paternity testing is an effective technique for defining relationships between common semen quality tests and fertility, especially in situations where reproductive performance of all the boars is high. Motility, normal acrosome morphology, average linear velocity of motile sperm, and the proportion of sperm capable of an acrosome reaction were all positively associated with boar fertility. However, concentrations of a 25.9kD/5.9pI seminal plasma protein were the best single semen characteristic for ranking boars in terms of their fertility.

PMID- 27707524 TI - Secondary depression in transdiagnostic group cognitive behavioral therapy among individuals diagnosed with anxiety disorders. AB - Anxiety and depression co-occur at high rates, and their comorbidity typically creates a more severe clinical presentation then either alone. The effect of comorbid depression appears to vary across anxiety and related disorders. Transdiagnostic treatments present a promising option to improve comorbid conditions by targeting shared factors (e.g., information processing biases). The purpose of this study was to examine the reciprocal effects of secondary depression in transdiagnostic group cognitive behavioral therapy for anxiety (TGCBT). 120 individuals diagnosed with a primary anxiety disorder, 42 of whom had a depressive diagnosis, were enrolled in 12 weeks of TGCBT. Depressed individuals were compared to those without a depressive diagnosis on both clinician-rated and self-reported anxiety and depression following TGCBT. Although depressed individuals scored higher on most indices of anxiety at pre treatment, both groups improved similarly with some evidence of greater improvement among those with comorbid depression. All individuals improved in self-reported depressive symptoms and comorbid depression improved to subclinical levels. These results posit TGCBT as an effective, efficient option for treating patients with anxiety and comorbid depression. PMID- 27707525 TI - Association of Pre-hospital ECG Administration With Clinical Outcomes in ST Segment Myocardial Infarction: A Systematic Review and Meta-analysis. AB - BACKGROUND: Delays in reperfusion for patients with myocardial ischemia leads to increased morbidity and mortality. The objective of this review was to identify, evaluate, and critically appraise the evidence on whether pre-hospital electrocardiography (ECG) reduces patient mortality and improves post-ST-segment myocardial infarction patient-oriented outcomes. METHODS: We searched PubMed/MEDLINE, EMBASE, and Cochrane Library (1990-2015) for controlled clinical studies. We also searched conference proceedings, trial registries, and reference lists of narrative and systematic reviews. Two reviewers independently identified and extracted data from studies that compared pre-hospital ECG with standard of care in patients with suspected myocardial infarction who underwent primary percutaneous coronary intervention. Internal validity was assessed using the Newcastle-Ottawa scale. RESULTS: We screened 21,197 citations and included 63 unique studies (plus 22 companion publications). Most studies were of moderate quality. Pre-hospital ECG was associated with significantly fewer deaths (relative risk, 0.68; 95% confidence interval [CI], 0.63-0.74; 45 studies; 71,315 patients; I2, 0%), reduced time to reperfusion (mean difference, -35.32 minutes; 95% CI, -44.02 to -26.61; 26 studies; 27,524 patients; I2, 97%), shorter hospital stays (mean difference, -0.63 days; 95% CI, -1.05 to -0.20; 10 studies; 39,275 patients; I2, 39%), and more patients had first medical contact to device time < 90 minutes than standard of care (relative risk, 1.77; 95% CI, 1.52-2.07; 11 studies; 20,991patients; I2, 93%). CONCLUSIONS: Use of pre-hospital ECG is associated with decreased mortality and overall better patient outcomes. PMID- 27707522 TI - Erythrocytes as Carriers for Drug Delivery in Blood Transfusion and Beyond. AB - Red blood cells (RBCs) are innate carriers that can also be engineered to improve the pharmacokinetics and pharmacodynamics of many drugs, particularly biotherapeutics. Successful loading of drugs, both internally and on the external surface of RBCs, has been demonstrated for many drugs including anti inflammatory, antimicrobial, and antithrombotic agents. Methods for internal loading of drugs within RBCs are now entering clinical use. Although internal loading can result in membrane disruption that may compromise biocompatibility, surface loading using either affinity or chemical ligands offers a diverse set of approaches for the production of RBC drug carriers. A wide range of surface determinants is potentially available for this approach, although there remains a need to characterize the effects of coupling agents to these surface proteins. Somewhat surprisingly, recent data also suggest that red cell-mediated delivery may confer tolerogenic immune effects. Questions remaining before widespread application of these technologies include determining the optimal loading protocol, source of RBCs, and production logistics, as well as addressing regulatory hurdles. Red blood cell drug carriers, after many decades of progress, are now poised to enter the clinic and broaden the potential application of RBCs in blood transfusion. PMID- 27707526 TI - Identifying and Managing Premature Ventricular Contraction-Induced Cardiomyopathy: What, Why, and How? AB - Premature ventricular contraction (PVC)-induced cardiomyopathy is increasingly being recognized as a reversible cause of left ventricular (LV) systolic dysfunction (LVSD). The diagnosis of PVC-induced cardiomyopathy is considered in subjects with high PVC burdens (> 10,000 per 24 hours) after excluding other known causes of LVSD. PVC suppression is the mainstay of the management of PVC induced cardiomyopathy, in addition to proven evidence-based medical therapy recommended for subjects with LVSD. Management strategies for PVC-induced cardiomyopathy include medical therapy and/or catheter ablation, with an increasing role for catheter ablation as a first-line therapy in view of the potential for permanent suppression of PVCs. Recovery of LVSD is typically a gradual process over months after effective suppression of PVCs. Last, asymptomatic patients with high PVC burdens and preserved LV systolic function appear to be at low risk over the intermediate term for developing LVSD. However, it is prudent to monitor LV function periodically because of the potential for deterioration of LV function observed during long-term follow-up in some subjects. PMID- 27707527 TI - Chemical agents for the sedation of agitated patients in the ED: a systematic review. AB - OBJECTIVE: Chemical agents commonly used to sedate agitated patients in the emergency department include benzodiazepines, antipsychotics, or a combination of the 2 classes. Our objective was to determine if a class or combination therapy is (1) more effective, as measured by the proportion sedated at 15-20 minutes and the need for repeat sedation, and (2) safer, as measured by the proportion of reported adverse events. METHODS: Systematic literature review and meta-analysis of studies comparing 2 or more chemical agents for sedation of agitated patients in the emergency department were carried out in PubMed, PsycINFO, Embase, and the Cochrane database. Meta-analyses for pairwise comparisons of drug class (benzodiazepine, antipsychotic, or combination) were carried out for each outcome: proportion sedated, need for repeat sedation, and adverse events. RESULTS: Seven studies with 1135 patients were included. At 15-20 minutes, the proportion of patients sedated was greater with combination therapy than benzodiazepines alone (risk ratio [RR] = 1.31, P < .0001). Antipsychotics and combination agents required significantly less repeat sedations than benzodiazepines alone (RR = 0.49, P < .0001 and RR = 0.64, P = .002). There was significant heterogeneity in adverse event data, with respiratory system adverse events (desaturation, and need for airway and ventilatory support) being the most commonly reported. Benzodiazepines were associated with a higher incidence of adverse events than antipsychotics or combination therapy. CONCLUSION: Combination therapy sedated a greater proportion of patients at 15-20 minutes than benzodiazepines alone. Antipsychotics and combination therapy were more effective, requiring less repeat doses for sedation than benzodiazepines. The risk of any adverse event was higher with benzodiazepines. PMID- 27707528 TI - Idarucizumab, a specific reversal agent for dabigatran: mode of action, pharmacokinetics and pharmacodynamics, and safety and efficacy in phase 1 subjects. AB - The direct oral anticoagulants (DOACs) provide a number of clinical advantages over vitamin K antagonists for the treatment of thromboembolism, including improved efficacy and safety, as well as no need for regular monitoring of anticoagulant effect. However, as with all anticoagulants, bleeding complications may occur, and anticoagulant reversal may be required in specific clinical situations, such as in patients experiencing spontaneous or traumatic bleeds, or in anticoagulated patients requiring emergency surgery or other invasive procedures. Therefore, several reversal agents for the DOACs are in development. This includes the specific reversal agent idarucizumab, which has been approved by the U.S. Food and Drug Administration and the European Medicines Agency for use in patients treated with dabigatran when urgent reversal of its anticoagulant effects is needed. Idarucizumab is a humanized monoclonal antibody fragment that binds with high affinity to free and thrombin-bound dabigatran, resulting in an almost irreversibly bound idarucizumab-dabigatran complex and thereby neutralizing dabigatran's anticoagulant activity. The reversal of the anticoagulant effects of dabigatran by idarucizumab has been demonstrated in animal bleeding models, in healthy volunteers with a range of ages and renal function, and in anticoagulated patients. In the phase 1 trials, at doses of 2 g or greater, idarucizumab resulted in immediate and complete reversal of the dabigatran anticoagulant effects and was well tolerated. In the absence of dabigatran, idarucizumab showed no effect on coagulation parameters or thrombin formation. These findings provide initial evidence that idarucizumab could provide a safe and effective means of reversing anticoagulant activity in patients treated with dabigatran in need of emergency surgery or in emergency bleeding situations. PMID- 27707529 TI - Antineuronal Nuclear Autoantibody Type 1/Anti-Hu-Associated Opsoclonus Myoclonus and Epilepsia Partialis Continua: Case Report and Literature Review. AB - BACKGROUND: Opsoclonus-myoclonus syndrome is a rare clinical condition that has been associated with neuroblastoma. There are few reported examples of ANNA 1/anti-Hu antibodies in children with neuroblastoma and opsoclonus-myoclonus, all in children aged less than three years of age. METHODS: We describe the new onset of focal seizures without alteration of consciousness and opsoclonus-myoclonus in an 11-year-old girl with ANNA-1/anti-Hu positivity and a paraspinal ganglioneuroblastoma. A systematic review of the literature of children with ANNA 1/anti-Hu positivity and malignancy was also performed. RESULTS: Fourteen patients were identified, eight of whom had opsoclonus-myoclonus. Although epilepsia partialis continua has been described in association with several neuronal autoantibodies, association with ANNA-1/anti-Hu has not been reported. CONCLUSIONS: We describe epilepsia partialis continua in a child with ANNA-1/anti Hu antibodies and neuroblastoma. Testing for antineuronal antibodies should be considered in children presenting with either opsoclonus-myoclonus or epilepsia partialis continua. PMID- 27707530 TI - Effect of patient age on treatment response in a study of the acute exacerbation of psychosis in schizophrenia. AB - Younger patients with schizophrenia have most likely experienced fewer adverse consequences of the illness than older patients who may have experienced a lifetime of treatment as well as socio-economic problems as a consequence of the illness. There is limited information regarding differential efficacy of long acting injectable (LAI) antipsychotic medications across the age span in patients with schizophrenia. We conducted a post hoc age and gender analysis of treatment response to aripiprazole lauroxil (AL; ARISTADA(r); Alkermes, Inc.), in a 12 week, double-blind, placebo-controlled, multinational, Phase 3 study evaluating two doses of AL (441mg and 882mg) versus placebo in adult patients experiencing an acute exacerbation of schizophrenia within the previous 2months. We examined change in the total Positive and Negative Syndrome Scale (PANSS) scores from baseline using analysis of covariance and categorical treatment response (defined as >=30% total PANSS score improvement from baseline) in the following age groups: <30, 30-39, 40-49, and 50-69years old. Age and gender did not moderate the treatment response in this study. Both AL 441mg and AL 882mg showed an early and significant improvement of the mean total PANSS scores and categorical treatment responses compared to placebo in all four age groups, including younger patients regardless of gender that was sustained over the 85-day treatment period. PMID- 27707531 TI - Suicidal behaviors in children and adolescents with psychotic disorders. AB - Suicide is the leading cause of premature death in individuals with psychotic disorders. Risk for onset of suicidal behaviors tends to begin in adolescence, remaining high into young adulthood. The present study aims to evaluate the interplay of early onset psychosis and suicide risk by examining suicidal behaviors (ideation, planning, and attempts) in children and adolescents with psychotic disorders (PD) compared to typically developing peers (TD). Twenty five youths were recruited and were diagnostically evaluated for psychosis. We found that the PD children exhibited significantly higher levels of suicidal behaviors than TD children, even when parsed into individual at-risk behaviors. PMID- 27707532 TI - [Perspective of intensive care nursing staff on the limitation of life support treatment]. AB - OBJECTIVE: To determine the perspective of intensive care nursing staff on the limitation of life support treatment (LLST) in the Intensive Care Units. METHOD: An exploratory qualitative study was carried out by applying the theory of Strauss and Corbin as the analysis tool. Constructivist paradigm. POPULATION: Nursing staff from three Intensive Care Units of Hospital Universitari de Bellvitge. Convenience sampling to reach theoretical saturation of data. Data collection through semi-structured interview recorded prior to informed consent. Rigor and quality criteria (reliability, credibility, transferability), and authenticity criteria: reflexivity. Demographic data was analysed using Excel. RESULTS: A total of 28 interviews were conducted. The mean age of the nurses was 35.6 years, with a mean seniority of 11.46 years of working in ICU. A minority of nurses (21.46%) had received basic training in bioethics. The large majority (85.7%) believe that LLST is not a common practice due to therapeutic cruelty and poor management with it. There is a correlation with the technical concepts; but among the main ethical problems is the decision to apply LLST. Nurses recognise that the decision on applying LLST depends on medical consensus with relatives, and they believe that their opinion is not considered. Their objective is trying to avoid suffering, and assist in providing a dignified death and support to relatives. CONCLUSIONS: There is still a paternalistic pattern between the doctor and patient relationship, where the doctor makes the decision and then agrees with the relatives to apply LLST. Organ failure and poor prognosis are the most important criteria for applying LLST. It is necessary to develop a guide for applying LLST, emphasising the involvement of nurses, patients, and their relatives.

PMID- 27707535 TI - Network analysis of the Quick Inventory of Depressive Symptomatology: Reanalysis of the STAR*D clinical trial. AB - Network analysis is yet to be used to examine patient-reported symptom severity and change during citalopram treatment for major depressive disorder. We aimed to identify: (I) network systems; (II) central symptoms; and (III) network differences, in patient-reported depression for baseline, endpoint and change scores. STAR*D data during citalopram treatment were reanalyzed to examine depression based on the Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR). Network analyses were computed from the QIDS-SR item-level severity scores at baseline and endpoint, and from estimated change scores based on mixed models, adjusted for confounding by dose and baseline severity. Centrality indices for each symptom were computed. Networks were contrasted for connectivity with permutation tests. Network analyses grouped symptoms consistently as: Sleep disturbances, cognitive and physical avolition, Affect and Appetite. Symptom centrality was highest for Energy at baseline, Mood at endpoint, and Mood and Concentration on change scores. Generally, permutation tests showed that the networks all significantly (p<.05) differed. Results demonstrated: (I) a replicable network group of the symptoms of depression that modestly mapped onto well-known mechanisms for depression; (II) symptoms with high centrality that may be future treatment targets (e.g., mood); and (III) that the form of the networks differed across treatment time-points, thereby contributing centrality as a possible mechanism to the initial severity debate. These findings highlight the utility of focusing on symptoms rather than total scores to understand how treatment unfolds, and tentative mechanisms.

AB - OBJECTIVES: To examine test-retest reliability of the SCAT3 for two consecutive seasons using a large sample of professional male ice hockey players, and to make recommendations for interpreting change on the test. DESIGN: A cross-sectional descriptive study. METHODS: Preseason baseline testing was administered in the beginning of the seasons 2013-2014 and 2014-2015 to 179 professional male hockey players in rink side settings. RESULTS: The test-retest reliabilities of the SCAT3 components were uniformly low. However, the majority of athletes remained grossly within their own individual performance range when two pre-season SCAT3 baseline scores were compared to published normative reference values. Being tested by the same person or a different person did not influence the results. It was uncommon for the Symptom score to worsen by >=3 points, the Symptom Severity score to worsen by >=5 points, SAC total score to worsen by >=3 points, M-BESS total error points to increase by >=3, or the time to complete Tandem Gait to increase by >=4s; each occurred in less than 10% of the sample. CONCLUSIONS: The SCAT3 has low test-retest reliability. Change scores should be interpreted with caution, and more research is needed to determine the clinical usefulness of the SCAT3 for diagnosing concussion and monitoring recovery. Careful examination of the natural distributions of difference scores provides clinicians with useful information on how to interpret change on the test. PMID- 27707537 TI - Exercise in patients with hypertrophic cardiomyopathy: A review of current evidence, national guideline recommendations and a proposal for a new direction to fitness. AB - Hypertrophic cardiomyopathy is a common genetic disorder with a prevalence of 1:500 in the general population. Amongst a varied spectrum of clinical presentations, the most feared complication of this cardiac disorder is sudden cardiac death. Although only a minority of patients with hypertrophic cardiomyopathy who suffer sudden cardiac death or resuscitated cardiac arrest do so during exercise, strenuous physical activity is regarded as an important trigger for these tragic outcomes. Furthermore, during exercise, patients with hypertrophic cardiomyopathy may develop augmentation of left ventricular outflow tract obstruction, myocardial ischemia, diastolic dysfunction and/or inappropriate vasodilation in non-exercising vascular beds. This in turn may lead to exertional dyspnea, chest pain or syncope. Accordingly, patients with hypertrophic cardiomyopathy are disqualified from competitive sports and in many cases are recommended to avoid strenuous physical activity of any kind. Nevertheless, avoidance of physical activity comes with a price. The positive effects of regular exercise have been extensively reported to convey a wide range of benefits including reduced cardiovascular events, weight reduction and improved wellbeing. Therefore, finding the right exercise level that will offer some of the benefits of physical activity without increasing the risk of sudden cardiac death is of utmost importance. In this review, we discuss the current evidence for and against exercise in this patient population and review national guideline recommendations. We also propose alternative fitness strategies including a novel fitness program implemented by our hypertrophic cardiomyopathy center which may be of particular usefulness for hypertrophic cardiomyopathy patients.

PMID- 27707539 TI - Therapeutic benefit observed with the CFTR potentiator, ivacaftor, in a CF patient homozygous for the W1282X CFTR nonsense mutation. AB - Premature termination codons (PTCs) in cystic fibrosis transmembrane conductance regulator (CFTR) gene result in nonfunctional CFTR protein and are the proximate cause of ~11% of CF causing alleles. Aminoglycosides and other novel agents are known to induce translational readthrough of PTCs, a potential therapeutic approach. Among PTCs, W1282X CFTR is unique, as it is a C-terminal CFTR mutation that can exhibit partial activity, even in the truncated state. The potentiator ivacaftor (VX-770) is approved for treating CF patients with G551D and other gating mutations. Based on previous studies demonstrating the beneficial effect of ivacaftor for PTC mutations following readthrough in vitro, we hypothesized that ivacaftor may enhance CFTR activity in CF patients expressing W1282X CFTR, and could be further enhanced by readthrough. Ivacaftor significantly increased CFTR activity in W1282X-expressing cells compared to R1162X CFTR cells, and was further enhanced by readthrough with the aminoglycoside G418. Primary nasal epithelial cells from a W1282X homozygous patient showed improved CFTR function in the presence of ivacaftor. Upon ivacaftor administration to the same patient, there was significant improvement in pulmonary exacerbation frequency, BMI, and insulin requirement, whereas FEV1 remained stable over 3years. These studies suggest that ivacaftor may have moderate clinical benefit in patients with preserved expression of the W1282X CFTR mutation by stimulating residual activity of the truncated protein, suggesting the need for further studies including the addition of efficacious readthrough agents. PMID- 27707540 TI - Evidence to inform the future for maternal and newborn health. AB - Despite the impressive progress gains for maternal and child health during the Millennium Development Goals era, over 5.6 million women and babies died in 2015 due to complications during pregnancy, birth and in the first month of life. In order to achieve the new mortality targets set out in the Sustainable Development Goals, there needs to be intentional efforts to maintain and accelerate action to end preventable maternal and newborn deaths and stillbirths. This paper outlines what progress is required to meet these new 2030 targets based on patterns of progress in the recent past; where the burden is the greatest; when to focus attention along the continuum of care; and what causes of death require concerted efforts. Priority actions include intentional and intensified political attention and investment in maternal-newborn health with particular focus on improving quality and experience of care around the time of birth with implementation at scale of integrated maternal-newborn health interventions across the continuum of care with commensurate investment targeted at the most vulnerable populations. Looking forward, improved data for decision making and accountability will be required. The health and survival of babies and their mothers are inextricably linked, and calls for coordinated efforts and innovation before and during pregnancy, in childbirth, and postnatally, in order to end preventable maternal, neonatal deaths and stillbirths.

AB - XRCC1 is a scaffold protein that provides for interaction of DNA polymerase, DNA ligase and damaged DNA. Genotyping was done for the five non-synonymous and synonymous variants of XRCC1 i.e. XRCC1, Arg194Trp, Pro206Pro, Arg280His, Arg399Gln, Gln632Gln. Logistic regression analysis was used to analyze the association of XRCC1 with lung cancer, followed by data mining analysis which included both Multi-dimensionality reduction (MDR) and Classification and Regression tree (CART) analysis so as to find possible interaction between SNPs on XRCC1 gene. Statistical analysis revealed XRCC1 Gln632Gln (OR=2.67, p=<0.001) depicted an overall high risk towards lung cancer. Histological subdivision revealed carriers of mutant genotype in case of XRCC1 Arg399Gln imposed a protective effect towards SQCC subtype. Likewise, mutant genotype in XRCC1 Pro206Pro implied a protective effect for SCLC subtype (OR=0.29, p=0.0017) on the contrary XRCC1 Gln632Gln showed a high risk in SQCC diseased group (OR=4.16, p=<0.0001). Combination of XRCC1 Gln632Gln with other SNPs revealed XRCC1 Gln632Gln with Arg194Trp (OR=2.10, p=0.03) and Pro206Pro (OR=5.6, p<0.0004) increased an overall risk towards lung cancer. Haplotype analysis illustrated haplotype block 11 (CGAGG) carrying minor allele for XRCC1 206 was associated with the highest risk towards lung cancer on the contrary block 4 (CAGAG) carrying mutant allele for XRCC1 399 significantly decreased the risk. Multi dimensionality reduction (MDR) results showed the three factor model comprising XRCC1 206, 632, 280 as the best model (CVC=10, prediction error=0.34). Further Classification and Regression tree (CART) analysis revealed terminal node 1 carrying mutant of XRCC1 632 and wild type of XRCC1 280 represented the highest risk group. Our results demonstrated high order interaction between SNPs of XRCC1 gene. This study depicted a positive association of XRCC1 Gln632Gln towards lung cancer, however XRCC1 Arg399Gln, Arg194Trp showed an overall no effect or protective effect. PMID- 27707542 TI - The Pol30-K196 residue plays a critical role in budding yeast DNA postreplication repair through interaction with Rad18. AB - PCNA plays critical roles in DNA replication and various DNA repair pathways including DNA damage tolerance (DDT). In budding yeast Saccharomyces cerevisiae, DDT (aka DNA postreplication repair, PRR) is achieved by sequential ubiquitination of PCNA encoded by POL30. Our previous studies revealed that two Arabidopsis PCNA genes were able to complement the essential function of POL30 in budding yeast, but failed to rescue the PRR activity. Here we hypothesize that a certain amino acid variation(s) is responsible for the difference, and identified K196 as a critical residue for the PRR activity. It was found that the pol30 K196V mutation abolishes Rad18 interaction and PRR activity, whereas nearby amino acid substitutions can partially restore Rad18 interaction and PRR activity. Together with the Pol30-Ub fusion data, we believe that we have identified a putative Rad18-binding pocket in Pol30 that is required for PCNA monoubiquitination and PRR. PMID- 27707543 TI - Effect of pH on ethanol-type acidogenic fermentation of fruit and vegetable waste. AB - The aim of this study was to investigate the possibility and optimal controlling strategy for ethanol-type acidogenic fermentation of fruit and vegetable waste by mixed microbial cultures. Four continuous stirred tank reactors (CSTR) were operated at various pHs (4.0, 5.0, 5.5, and 6.0) with an organic loading rate of 13gVS/(Ld) and hydraulic retention time of 3d. Butyrate-type fermentation was observed at pH 5.0, 5.5, and 6.0. Conversely, at pH 4.0, ethanol-type fermentation was observed with a high mass concentration and proportion (of total fermentative products) of ethanol, which were 6.7g/L and 88.8%, respectively. However, the total concentration of ethanol-type fermentative products substantially decreased from days 22-25. The optimal pH of ethanol-type fermentative microorganisms was investigated by using batch experiments with pH controlled at 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, and 7.0 and results showed that the maximum ethanol concentration and relatively highest acidogenic rate were found at pH of 5.5. The pH in the long term CSTR was changed from 4.0 to 5.5 to improve ethanol-type fermentation and results showed that ethanol-type fermentation was improved temporarily, however, was followed by the reappearance of butyrate-type fermentation. In addition, ethanol-type fermentation recovered once more when pH was reverted to 4.0. Therefore, the results of this study suggest that a process of dynamic, sequenced pH control with the order pH 4.0, 5.5 and 4.0 might be a feasible controlling strategy for continuous and stable ethanol-type fermentation. PMID- 27707544 TI - Mealtime Structure and Responsive Feeding Practices Are Associated With Less Food Fussiness and More Food Enjoyment in Children. AB - OBJECTIVE: To identify associations between structure-related and non-responsive feeding practices and children's eating behaviors. DESIGN: Cross-sectional online survey design. PARTICIPANTS: Parents (n = 413) of 1- to 10-year-old children. MAIN OUTCOME MEASURES: Parental feeding practices and child eating behaviors were measured via the validated Feeding Practices and Structure and Children's Eating Behaviour questionnaires. ANALYSIS: Associations between parental feeding practices and children's eating behaviors were tested using hierarchical multivariable linear regression models, adjusted for covariates. RESULTS: Feeding practices accounted for 28% and 21% of the variance in food fussiness and enjoyment of food, respectively (P < .001). For all other eating behaviors the amount of variance explained by feeding practices was < 10% (P < .001). Key findings were that more structure and less non-responsive practices were associated with lower food fussiness and higher enjoyment of food. CONCLUSIONS AND IMPLICATIONS: Overall, the findings suggested that mealtime structure and responsive feeding are associated with more desirable eating behaviors. Contrary to predictions, there was no evidence to indicate that these practices are associated with better self-regulation of energy intake. Longitudinal research and intervention studies are needed to confirm the importance of these feeding practices for children's eating behaviors and weight outcomes. PMID- 27707545 TI - Surgical embryo collection but not nonsurgical embryo transfer compromises postintervention prolificacy in sows. AB - Recent advances in nonsurgical deep uterine (NsDU) embryo transfer (ET) technology allow the noninvasive transfer of porcine embryos into recipients, overcoming the most important impediment for commercial ET in this species. Although many factors in the porcine ET-field have been recently evaluated, many others remain to be explored. We investigated here the future reproductive performance of donors and recipients after artificial insemination subsequent to the default surgical embryo recovery approach and to the NsDU-ET procedure, respectively. Although surgical embryo collection did not influence subsequent farrowing rates (90.5%), litter size decreased severely (8.9 +/- 0.8 piglets) compared to presurgery (10.8 +/- 0.3 piglets) and control group (10.7 +/- 0.3 piglets). In contrast, NsDU-ETs did neither affect fertility nor prolificacy of recipients in the cycle subsequent to ET, regardless of whether they were pregnant after NsDU-ET or not. These results indicate that while the surgical embryo collection procedure compromises the reproductive future of donor sows, the NsDU-ET approach does not affect the reproductive potential of the recipients after reintroduction to the breeding stock of the farm. Further research is thus needed to improve surgical embryo collection. PMID- 27707547 TI - Continuous contact with females in estrus throughout the year enhances testicular activity and improves seminal traits of male goats. AB - The "female effect" consists in the stimulation of males' reproductive activity by different signals emitted by females. This stimulation leads to endocrine and behavioral changes that may modify the seasonal pattern of male ruminants. The aims of this experiment were (1) to describe the local reproductive seasonal pattern of Gabon bucks and (2) to determine if continuous chemical, auditory, and visual contact with does in estrus enhances bucks' testicular activity and improves seminal traits throughout the year and modify their seasonal pattern. We used 16 adult Gabon bucks assigned to two experimental groups: nine bucks remained continuously isolated from females (isolated bucks, group IB) and seven bucks were in continuous chemical, auditory, and visual contact through a fence line with does in estrus (stimulated bucks, group SB). During 13 months, scrotal circumference and testosterone concentration were measured weekly and testicular echogenicity was measured every 2 weeks. Also, sperm motility mass and percentage of abnormal spermatozoa were determined, and sperm concentration and total number of motile spermatozoa were calculated every 2 weeks. Testicular echogenicity was greater in IB than that in SB bucks (P < 0.0001), but there were no differences in scrotal circumference. Overall, testosterone concentration was greater in IB than that in SB bucks (P = 0.04), but from late winter to mid-summer, when testosterone concentration presented basal concentrations, SB bucks had greater values than IB bucks (P = 0.004). Sperm concentration (P = 0.05) and sperm mass motility (P = 0.01) were greater in SB than that in IB bucks, and the total number of progressive motile spermatozoa tended to be greater in SB than in that IB bucks (P = 0.1). The percentage of abnormal spermatozoa was lower in SB than in IB bucks in several time points (P < 0.0001). Testicular and seminal traits were better from the end of the spring until mid-autumn. We concluded that does in estrus stimulated bucks' testicular activity, including better seminal quality and a greater increase of testicular fluid content than bucks isolated from females. However, the general seasonal pattern was not modified by stimulation with does in estrus. PMID- 27707546 TI - Split-time artificial insemination in beef cattle: II. Comparing pregnancy rates among nonestrous heifers based on administration of GnRH at AI. AB - This experiment was designed to evaluate split-time artificial insemination (AI) in beef heifers following administration of the 14-day controlled internal drug release (CIDR)-prostaglandin F2alpha (PG) protocol and to compare pregnancy rates among nonestrous heifers based on administration of GnRH at AI. Estrus was synchronized for 1138 heifers across six locations. Heifers received a CIDR insert (1.38 g progesterone) on Day 0 with removal on Day 14. Estrus detection aids (Estrotect) were applied at PG (25 mg), 16 days after CIDR removal on Day 30. Heifers were assigned to balanced treatments based on reproductive tract score and weight, and treatments were represented within each location. Split time AI was performed at 66 and 90 hours after PG, and estrus was recorded at these times. Heifers in both treatments that exhibited estrus by 66 hours were inseminated and did not receive GnRH, whereas AI was delayed 24 hours until 90 hours after PG for heifers that failed to exhibit estrus by 66 hours. For heifers in treatment 1 that were inseminated at 90 hours, GnRH (100 MUg) was administered concurrent with AI at 90 hours. Heifers in treatment 2 that were inseminated at 90 hours did not receive GnRH. Estrous response did not differ between treatments at 66 hours after PG (treatment 1 = 70%; treatment 2 = 71%; P = 0.58) or during the 24-hour delay period (treatment 1 = 59%; treatment 2 = 52%; P = 0.21). There was no effect of treatment on pregnancy rates resulting from AI for heifers inseminated at 66 hours (treatment 1 = 58%; treatment 2 = 62%; P = 0.86) or 90 hours (treatment 1 = 44%; treatment 2 = 39%; P = 0.47) after PG; and there was no difference between treatments when considering total AI pregnancy rate (treatment 1 = 54%; treatment 2 = 56%; P = 0.60). Ovulation was confirmed via ultrasonography for a subset of heifers that failed to exhibit estrus prior to 90 hours after PG. For heifers that failed to exhibit estrus by 90 hours, success of ovulation did not differ between treatments (treatment 1 = 52%; treatment 2 = 50%; P = 0.64) nor did AI pregnancy rate (treatment 1 = 24%; treatment 2 = 15%; P = 0.97). In summary, when split-time AI was used in conjunction with the 14-day CIDR-PG protocol in heifers, comparable pregnancy rates were achieved without administering GnRH. PMID- 27707549 TI - Twelve-Month Outcomes of Ranibizumab vs. Aflibercept for Neovascular Age-Related Macular Degeneration: Data from an Observational Study. AB - PURPOSE: To directly compare visual acuity (VA) outcomes with ranibizumab vs. aflibercept for eyes with neovascular age-related macular degeneration (nAMD) treated in routine clinical practice. DESIGN: Database observational study. PARTICIPANTS: Treatment-naive eyes with nAMD tracked by the Fight Retinal Blindness outcome registry that commenced anti-vascular endothelial growth factor therapy with ranibizumab or aflibercept between December 1, 2013, and January 31, 2015. Eyes were matched at baseline for VA, age, and choroidal neovascular membrane (CNV) size. METHODS: Locally weighted scatterplot smoothing curves were used to display VA results. Eyes that switched or discontinued treatment were included with their last observation carried forward. MAIN OUTCOME MEASURES: Change in mean VA (number of letters read on a logarithm of the minimum angle of resolution chart); number of injections and visits; proportion of eyes with inactive CNV over 12 months. RESULTS: We identified 394 eyes (197 treated with ranibizumab and 197 with aflibercept) from 372 patients who received treatment from 34 practitioners. Baseline parameters were well matched. The mean (standard deviation [SD]) VA of ranibizumab-treated eyes increased from 58.6 (20.3) letters at baseline to 62.3 (23.9) (+3.7 [95% confidence interval {CI} 1.4-6.1]) letters (P = 0.001), compared with 58.9 (19.2) letters at baseline to 63.1 (21.5) (+4.26 [95% CI 2.0-6.5]) letters (P < 0.001) for eyes receiving aflibercept. The difference in change in crude VA of 0.6 letters between the 2 groups was not statistically significant (P = 0.76), nor was the difference in adjusted mean VA of the 2 groups (P = 0.26). In completers, the mean (SD) numbers of injections (8.1 [2.1] vs. 8.0 [2.3]; P = 0.27) and visits (9.6 [3.0] vs. 9.5 [3.1]; P = 0.15) did not differ between the 2 groups. The adjusted proportion of eyes in which the CNV lesion was graded as inactive during the study was similar between the eyes receiving ranibizumab and aflibercept (74% vs. 77%, respectively; P = 0.63). CONCLUSIONS: Visual acuity outcomes at 12 months did not differ between ranibizumab and aflibercept used for nAMD in this large observational study, nor was a difference in treatment frequency found. PMID- 27707548 TI - Glaucoma Risk Alleles in the Ocular Hypertension Treatment Study. AB - PURPOSE: Primary open-angle glaucoma (POAG) is a major cause of blindness and visual disability. Several genetic risk factors for POAG and optic nerve features have been identified. We measured the relative risk for glaucoma that these factors contribute to participants in the Ocular Hypertension Treatment Study (OHTS). DESIGN: Comparative series. PARTICIPANTS: One thousand fifty-seven of 1636 participants (65%) of the OHTS were enrolled in this genetics ancillary study. METHODS: Samples of DNA were available from 1057 OHTS participants. Of these, 209 developed POAG (cases) and 848 did not develop glaucoma (controls) between 1994 and 2009. The frequencies of 13 risk alleles previously associated with POAG or with optic disc features in other cohorts were compared between POAG cases and controls in the OHTS cohort using analyses of variance. The 2 largest subgroups, non-Hispanic whites (n = 752; 70.7%) and blacks (n = 249, 23.7%), also were analyzed separately. The probability of glaucoma developing over the course of the OHTS was compared between participants stratified for transmembrane and coiled-coil domains 1 (TMCO1) risk alleles using Kaplan-Meier and Cox proportional hazards analyses. MAIN OUTCOME MEASURES: Association of POAG with known genetic factors. RESULTS: No association was detected between the known POAG risk alleles when the OHTS cohort was examined as a whole. However, in the subgroup of non-Hispanic whites, allele frequencies at the TMCO1 locus were statistically different between cases and controls (P = 0.00028). By 13 years, non-Hispanic white participants with TMCO1 risk alleles had a 12% higher cumulative frequency of glaucoma developing than participants with no TMCO1 risk alleles. Moreover, the Cox proportional hazard analysis demonstrated that TMCO1 alleles increased relative risk comparable with that of some previously analyzed clinical measures (i.e., intraocular pressure). CONCLUSIONS: The size of the OHTS cohort and its composition of 2 large racial subgroups may limit its power to detect some glaucoma risk factors. However, TMCO1 genotype was found to increase the risk of glaucoma developing among non-Hispanic whites, the largest racial subgroup in the OHTS cohort, at a magnitude similar to clinical predictors of disease that long have been associated with glaucoma. PMID- 27707550 TI - Twenty-four-Month Outcomes of the Ranibizumab for Edema of the Macula in Diabetes - Protocol 3 with High Dose (READ-3) Study. AB - PURPOSE: To compare 2.0 mg ranibizumab (RBZ) injections with 0.5 mg RBZ for eyes with center-involved diabetic macular edema (DME). DESIGN: Randomized, controlled, double-masked (to the dose), interventional, multicenter clinical trial. PARTICIPANTS: A total of 152 patients (152 eyes) with DME. METHODS: Eligible eyes were randomized in a 1:1 ratio to 0.5 mg (n = 77) or 2.0 mg (n = 75) RBZ. Study eyes received 6 monthly mandatory injections followed by as-needed injections until month 24. MAIN OUTCOME MEASURES: The primary efficacy end point of the study was mean change in best-corrected visual acuity (BCVA) and central foveal thickness (CFT) at month 6. Secondary outcomes included the mean change in BCVA and CFT at month 24, and incidence and severity of systemic and ocular adverse events through month 24. RESULTS: A total of 152 eyes were randomized in the study. At month 24, the mean improvement from baseline BCVA was +11.06 letters in the 0.5 mg RBZ group (n = 59) and +6.78 letters in the 2.0 mg RBZ group (n = 54) (P = 0.02). The mean numbers of RBZ injections through month 24 were 18.4 and 17.3 in the 0.5 mg and 2.0 mg RBZ groups, respectively (P = 0.08). The mean change in CFT was -192.53 MUm in the 0.5 mg RBZ group and -170.64 MUm in the 2.0 mg RBZ group (P = 0.41). By month 24, 3 deaths had occurred in the 0.5 mg RBZ group and 3 deaths had occurred in the 2.0 mg RBZ group; 5 of these 6 deaths occurred secondary to cardiovascular causes, and 1 death occurred as the result of severe pneumonia. All 5 patients with a cardiovascular cause of death had a history of coronary heart disease. CONCLUSIONS: At month 24, there were significant visual and anatomic improvements in both groups, with subjects in the 0.5 mg RBZ group gaining more vision. Visual and anatomic gains achieved at month 6 were largely maintained through month 24. No new safety events were identified. In this study population, 2.0 mg RBZ does not appear to provide additional benefit over 0.5 mg RBZ. PMID- 27707551 TI - The awareness to metabolic syndrome among hospital health providers. AB - BACKGROUND: Metabolic syndrome (MetS) was shown to be related to a variety of diseases. High level of vigilance for the diagnosis of MetS is expected among health providers. We evaluated the level of awareness to MetS among physician and nurses working in a central hospital. METHODS AND RESULTS: A specially designed anonymous questionnaire was used, including both open and multiple choice questions set to evaluate the participant's awareness to MetS. The study included 126 participants, 71% physicians and 29% nurses. Mean age was 36.2+/-3.8 years. Among physicians, 68.5% were residents and 45.5% were internists. 98% of the participants stated that they were familiar with the term MetS and that they treat MetS patients regularly. Most participants knew the correct number of criteria included in MetS definition and the number of criteria needed for MetS diagnosis (84% and 90%, respectively). However, only 12% were able to discriminate correctly all MetS cases from non-MetS ones. Physicians performed better than nurses (15.6% and 3.1%, respectively, P=0.003). Neither, field of practice nor seniority was found to have a significant influence on the results. The frequency of recommendation for MetS risk factor modulation in the discharge files was also analyzed. Such recommendations were scarcely given, with cardiology department being the exception (80% of discharge files from cardiology department compared with less than 20% in other departments). CONCLUSION: Though hospital workers showed high level of awareness to the existence of MetS, they failed to differentiate correctly MetS cases from non-MetS ones. PMID- 27707552 TI - Comparative Effectiveness of 12 Treatment Strategies for Preventing Contrast Induced Acute Kidney Injury: A Systematic Review and Bayesian Network Meta analysis. AB - BACKGROUND: To simultaneously evaluate the relative efficacy of multiple pharmacologic strategies for preventing contrast-induced acute kidney injury (AKI). STUDY DESIGN: Systematic review containing a Bayesian network meta analysis of randomized controlled trials. SETTING & POPULATION: Participants undergoing diagnostic and/or interventional procedures with contrast media. SELECTION CRITERIA FOR STUDIES: Randomized controlled trials comparing the active drug treatments with each other or with hydration alone. INTERVENTION: Any of the following drugs in combination with hydration: N-acetylcysteine (NAC), theophylline (aminophylline), fenoldopam, iloprost, alprostadil, prostaglandin E1, statins, statins plus NAC, bicarbonate sodium, bicarbonate sodium plus NAC, ascorbic acid (vitamin C), tocopherol (vitamin E), alpha-lipoic acid, atrial natriuretic peptide, B-type natriuretic peptide, and carperitide. OUTCOMES: The occurrence of contrast-induced AKI. RESULTS: The trial network included 150 trials with 31,631 participants and 4,182 contrast-induced AKI events assessing 12 different interventions. Compared to hydration, ORs (95% credible intervals) for contrast-induced AKI were 0.31 (0.14-0.60) for high-dose statin plus NAC, 0.37 (0.19-0.64) for high-dose statin alone, 0.37 (0.17-0.72) for prostaglandins, 0.48 (0.26-0.82) for theophylline, 0.62 (0.40-0.88) for bicarbonate sodium plus NAC, 0.67 (0.54-0.81) for NAC alone, 0.64 (0.41-0.95) for vitamins and analogues, 0.70 (0.29-1.37) for natriuretic peptides, 0.69 (0.31-1.37) for fenoldopam, 0.78 (0.59-1.01) for bicarbonate sodium, and 0.98 (0.41-2.07) for low-dose statin. High-dose statin plus NAC or high-dose statin alone were likely to be ranked the best or the second best for preventing contrast-induced AKI. The overall results were not materially changed in metaregressions or subgroup and sensitivity analyses. LIMITATIONS: Patient-level data were unavailable; unable to include some treatment agents; low event rates; imbalanced distribution of participants among treatment strategies. CONCLUSIONS: High-dose statins plus hydration with or without NAC might be the preferred treatment strategy to prevent contrast-induced AKI in patients undergoing diagnostic and/or interventional procedures requiring contrast media.

PMID- 27707554 TI - The construction and validity analysis of AQHI based on mortality risk: A case study in Guangzhou, China. AB - The current air quality indices have been criticized for not capturing combined health effects of multiple air pollutants. We proposed an Air Quality Health Index (AQHI) based on the air pollution-mortality associations for communicating health risks of air pollution. Time-series studies were conducted to estimate the associations between air pollutants including sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), suspended particulate matter smaller than 2.5 MUm in aerodynamic diameter (PM2.5) and mortality in Guangzhou from 2012 to 2015. The sum of excess mortality risk was calculated to construct the AQHI, which was then adjusted to an arbitrary scale. We then assessed the validity of AQHI. An interquartile increase (IQR) of AQHI was associated with 3.61% [95% confidence interval (95% CI), 2.85%-4.37%], 3.73% (95%CI, 2.18%-5.27%) and 4.19% (95%CI, 2.87%-5.52%) increase of mortality, respiratory and cardiovascular hospital admissions, respectively. Compared with the currently used Air Quality Index (AQI), AQHI had higher effects on mortality and morbidity. Our study suggests that AQHI might comprehensively capture the combined effects of air pollution, which make it be a more valid communication tool of air pollution-related health risk. PMID- 27707553 TI - Preeclampsia and ESRD: The Role of Shared Risk Factors. AB - BACKGROUND: Several registry-based studies, using diagnostic codes, have suggested that preeclampsia is a risk factor for end-stage renal disease (ESRD). However, because the 2 diseases share risk factors, the true nature of their association remains uncertain. Our goals were to conduct a population-based study to determine the magnitude of the association between preeclampsia and ESRD and evaluate the role of shared risk factors. STUDY DESIGN: Population-based nested case-control study. SETTING & PARTICIPANTS: The US Renal Data System was used to identify women with ESRD from a cohort of 34,581 women who gave birth in 1976 to 2010 in Olmsted County, MN. 44 cases of ESRD were identified and each one was matched to 2 controls based on year of birth (+/-1 year), age at first pregnancy (+/-2 years), and parity (+/-1 or >=4). PREDICTOR: Preeclamptic pregnancy, confirmed by medical record review. OUTCOME: ESRD. MEASUREMENTS: Prepregnancy serum creatinine and urine protein measurements were recorded. Comorbid conditions existing prior to pregnancy were abstracted from medical records and included kidney disease, obesity, diabetes, and hypertension. RESULTS: There was evidence of kidney disease prior to the first pregnancy in 9 of 44 (21%) cases and 1 of 88 (<1%) controls. Per chart review, 8 of 44 (18%) cases versus 4 of 88 (5%) controls had preeclamptic pregnancies (unadjusted OR, 4.0; 95% CI, 1.21 13.28). Results were similar after independent adjustment for race, education, diabetes, and hypertension prior to pregnancy. However, the association was attenuated and no longer significant after adjustment for obesity (OR, 3.25; 95% CI, 0.93-11.37). LIMITATIONS: The limited number of ESRD cases and missing data for prepregnancy kidney function. CONCLUSIONS: Our findings confirm that there is a sizable association between preeclampsia and ESRD; however, obesity is a previously unexplored confounder. Pre-existing kidney disease was common, but not consistently coded or diagnosed. PMID- 27707557 TI - Where the thread of home births never broke - An interview with Susanne Houd. AB - BACKGROUND: The option of a planned home birth defies medical and social normativity across countries. In Denmark, despite the dramatic decline in the home birth rates between 1960 and 1980, the right to choose the place of birth was preserved. Little has been produced documenting this process. AIM: To present and discuss Susanne Houd's reflection on the history and social dynamics of home birth in Denmark, based in an in-depth interview. METHODS: This paper is part of wider Short Term Scientific Mission (STSM), in which this interview was framed as oral history. The whole interview transcript is presented, keeping the highest level of detail. FINDINGS: In Susanne Houd's testimony, four factors were highlighted as contributing to the decline in the rate of home births from the 1960s to the 1970s: new maternity hospitals; the development of obstetrics as a research-based discipline; the compliance of midwives; and a shift in women's preference, favouring hospital birth. The development of the Danish home birth models was described by Susanne Houd in regard to the processes associated with the medicalisation of childbirth, the role of consumers, and the changing professional dynamics of midwifery. CONCLUSION: An untold history of home birth in Denmark was documented in this testimony. The Danish childbirth hospitalisation process was presented as the result of a complex interaction of factors. Susanne Houd's reflections reveal how the concerted action of consumers and midwives, framed as a system-challenging praxis, was the cornerstone for the sustainability of home birth models in Denmark. PMID- 27707558 TI - A comparison of language use in pro- and anti-vaccination comments in response to a high profile Facebook post. AB - BACKGROUND: Vaccinations are important for controlling the spread of disease, yet an increasing number of people are distrustful of vaccines, and choose not to (fully) vaccinate themselves and their children. One proposed contributor to this distrust is anti-vaccination misinformation available on the internet, where people search for and discuss health information. The language people use in these discussions can provide insights into views about vaccination. METHODS: Following a prominent Facebook post about childhood vaccination, language used by participants in a comment thread was analysed using LIWC (Linguistic Inquiry and Word Count). Percentage of words used across a number of categories was compared between pro-vaccination, anti-vaccination, and unrelated (control) comments. RESULTS: Both pro- and anti-vaccination comments used more risk-related and causation words, as well as fewer positive emotion words compared to control comments. Anti-vaccine comments were typified by greater analytical thinking, lower authenticity, more body and health references, and a higher percentage of work-related word use in comparison to pro-vaccine comments, plus more money references than control comments. In contrast, pro-vaccination comments were more authentic, somewhat more tentative, and evidenced higher anxiety words, as well as more references to family and social processes when compared to anti vaccination comments. CONCLUSION: Although the anti-vaccination stance is not scientifically-based, comments showed evidence of greater analytical thinking, and more references to health and the body. In contrast, pro-vaccination comments demonstrated greater comparative anxiety, with a particular focus on family and social processes. These results may be indicative of the relative salience of these issues and emotions in differing understandings of the benefits and risks of vaccination. Text-based analysis is a potentially useful and ecologically valid tool for assessing perceptions of health issues, and may provide unique information about particular concerns or arguments expressed on social media that could inform future interventions. PMID- 27707559 TI - Treatment of Chlamydia-associated ocular disease via a recombinant protein based vaccine in the koala (Phascolarctos cinereus). AB - Koalas (Phascolarctos cinereus) are affected by debilitating chlamydial disease that can lead to blindness, infertility, and death. The causative agent is the intracellular bacterium Chlamydia pecorum. While antibiotics can be used to treat koala chlamydial infection, they are often ineffective or cause severe dysbiosis to the animal's unique gut flora. Recent work has progressed on the development of a protective vaccine for Chlamydia in the koala. This study demonstrates that the use of a vaccine can have a positive effect in koalas already with clinical signs of ocular disease, suggesting a possible therapeutic effect and an alternative to antibiotic therapy. PMID- 27707560 TI - Application of a real time Polymerase Chain Reaction (PCR) assay for the early diagnosis of human leptospirosis in Sri Lanka. AB - Leptospirosis has a major impact on health in Sri Lanka but is probably grossly under-recognized due to difficulties in clinical diagnosis and lack of diagnostic laboratory services. The objective of this study was to establish and evaluate a SYBR Green-based real-time Polymerase Chain Reaction (rt-PCR) assay for early, rapid and definitive laboratory diagnosis of leptospirosis in Sri Lanka. The rt PCR assay was established and analytical specificity and sensitivity were determined using reference DNA samples. Evaluation of the assay for diagnosis of clinical samples was performed using two panels of serum samples obtained from 111 clinically suspected adult patients. Patients were confirmed as leptospirosis (n = 65) and non-leptospirosis (n = 30) by the Patoc - MAT. Other 16 samples gave ambiguous results. The analytical sensitivity of the rt-PCR was approximately 60 genome copies and no cross-reactivity was observed with saprophytic Leptospira spp. and other pathogenic microorganisms. Based on confirmation with Patoc-MAT on paired samples this corresponds to a diagnostic sensitivity and specificity of 67.7% (44/65) and 90.0% (27/30), respectively. This study showed that rt-PCR has the potential to facilitate rapid and definitive diagnosis of leptospirosis during early phase of infection in Sri Lanka.

AB - INTRODUCTION AND OBJECTIVES: The present article reports the characteristics and results of heart transplants in Spain since this therapeutic modality was first used in May 1984. METHODS: We describe the main features of recipients, donors, surgical procedures, and results of all heart transplants performed in Spain until December 31, 2015. RESULTS: A total of 299 cardiac transplants were performed in 2015, with the whole series comprising 7588 procedures. The main transplant features in 2015 were similar to those observed in recent years. A remarkably high percentage of transplants were performed under emergency conditions and there was widespread use of circulatory assist devices, particularly continuous-flow left ventricular assist devices prior to transplant (16% of all transplants). Survival has significantly improved in the last decade compared with previous time periods. CONCLUSIONS: During the last few years, between 250 and 300 heart transplants have consistently been performed each year in Spain. Despite a more complex clinical context, survival has increased in recent years. PMID- 27707563 TI - "Subclinical" Leaflet Thrombosis in Transcatheter Aortic Valve Implantation: A Latent Risk? PMID- 27707564 TI - A Systematic Review and Meta-Analysis Examining the Differences Between Nonsurgical Management and Percutaneous Fixation of Minimally and Nondisplaced Scaphoid Fractures. AB - PURPOSE: The optimal management of undisplaced scaphoid fractures remains controversial. A systematic review was conducted to assess the outcomes of acute, undisplaced scaphoid fractures managed with cast immobilization versus percutaneous or miniopen screw fixation in terms of time to return to work (RTW), time to union, and morbidity. METHODS: PubMed MEDLINE, Ovid MEDLINE, EMBASE, SCOPUS, and Cochrane electronic databases were searched over the period 1974 to 2015. Key words included "scaphoid fracture," "navicular fracture," "hand," "immobilization," "cast," "conservative," "percutaneous," "screw fixation," "mini open," and "minimally invasive." A 2-step review process was done by 2 independent reviewers (H.A. and J.K.) using the following criteria: (1) acute undisplaced scaphoid fracture, (2) English language, (3) RTW duration objectively reported, (5) age older than 15 years, and (5) studies with more than 10 patients. Patient demographics, duration of immobilization, time to RTW, time to union, and complications were extracted. The methodological quality of each study included was assessed independently. Meta-analysis was performed for comparative trials. RESULTS: Ten studies met the inclusion criteria: 6 comparative studies and 4 case series. Patients were divided into 2 groups: cast immobilization (group 1) and percutaneous fixation (group 2). Average time to RTW was 77 days for group 1 versus 46 days for group 2. Average time to radiographic union was 79 days for group 1 versus 44 days for group 2. There was no significant difference in complication rate between the groups (7% in group 1 vs 14% in group 2). CONCLUSIONS: Percutaneous fixation of acute undisplaced scaphoid fractures has union rates comparable with those of nonsurgical cast immobilization but with faster RTW and time to union without a significant difference in complication rate. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II. PMID- 27707565 TI - Relationship Between Ulnar Variance, Cortical Bone Density, and Load to Failure in the Distal Radius at the Typical Site of Fracture Initiation. AB - PURPOSE: Increased ulnar variance has been shown to lead to diminished load borne by the distal radius. The purpose of this study was to determine the correlations among ulnar variance, bone mineral density, and load to failure at the distal radius. METHODS: Posteroanterior radiographs and computed tomographic scans were taken of 12 cadaveric forearms in neutral rotation. Ulnar variance was measured for each wrist by the method of perpendiculars. Measurements of cortical, trabecular, and combined bone density were made at the distal radius. We performed linear regression analysis and correlation analysis to determine the relationship between bone densities and ulnar variance measurements. Next, we loaded the 12 cadaveric radii to failure under axial compression. Linear regression analysis and correlation analysis were then performed to determine the relationship between load to failure and both ulnar variance and cortical density. RESULTS: Increased ulnar variance was significantly correlated with decreased cortical bone density at the distal radius and both were correlated with decreased load to failure. We found no correlation between ulnar variance and trabecular density or combined trabecular and cortical bone density at the distal radius. CONCLUSIONS: Our study found that increased ulnar variance and decreased cortical bone mineral density correlates with decreased load to failure under axial compression. CLINICAL RELEVANCE: Ulnar variance is linked to both bone quality and load to failure at the distal radius. PMID- 27707566 TI - Simultaneous control of glycemic, blood pressure, and lipid significantly reduce the risk of renal progression in diabetes patients. AB - BACKGROUND AND AIM: Hyperglycemic, hypertension, and lipid abnormalities are risk factors for diabetic kidney disease However, no study has discussed the association of the simultaneous control of glycemic, blood pressure, and lipids with renal function among diabetes patients. Thus, this study examined the interactive effects of the intensive control of all 3 conditions on the progression of renal function. MATERIALS AND METHODS: The study population was derived from eight hospitals in Taiwan from October 2008 to April 2015. Demographic characteristics were collected using structured questionnaires. Clinical variables were obtained from medical chart review. The renal progression was defined as a decline in the eGFR by more than 25% according to the baseline eGFR. RESULTS: Total of 1602 diabetes patients were included in the study analysis, the mean age was 63.03+/-10.98years, 55.56% were men. Compared to the simultaneous control of glycemic, blood pressure and lipid group, the poor control of all three diseases had the highest risk of renal progression, with an adjusted OR of 2.21 (95% CI, 1.26-3.86). Even if the patients with an intensive control of lipid, the result showed that the poor control of both glycemic and hypertension was associated with the increased risk of renal progression than the reference group. CONCLUSION: This study demonstrated that the simultaneous poor control of glycemic, blood pressure, and lipid had the highest risk of renal progression. Thus, patients with type 2 diabetes should not only control glycemic but also manage their blood pressure and lipid.

PMID- 27707570 TI - Stream invertebrate community structure at Canadian oil sands development is linked to concentration of bitumen-derived contaminants. AB - In Canada, the Athabasca oil sands deposits are a source of bitumen-derived contaminants, reaching the aquatic environment via various natural and anthropogenic pathways. The ecological effects of these contaminants are under debate. To quantify the effects of bitumen-derived contaminants we monitored the aquatic exposure of polycyclic aromatic hydrocarbons (PAHs), metals, and naphthenic acids as well as the invertebrate community in the Athabasca River and its tributaries. PAH concentrations over 3 consecutive years were related to discharge and were highest in the year with high autumn rainfall. In the year with the highest PAH concentrations, these were linked with adverse effects on the aquatic invertebrate communities. We observed relative effects of the composition and concentration of contaminants on the invertebrate fauna. This is reflected by the composition and abundance of invertebrate species via the use of the species' traits "physiological sensitivity" and "generation time". Applying the SPEAR approach we observed alterations of community structure in terms of an increased physiological sensitivity and a decrease of generation time for the average species. These effects were apparent at concentrations 100 times below the acute sensitivity of the standard test organism Daphnia magna. To rapidly identify oil sands related effects in the field we designed a biological indicator system, SPEARoil, applicable for future routine monitoring.

PMID- 27707571 TI - Train-induced field vibration measurements of ground and over-track buildings. AB - Transit-oriented development, such as metro depot and over-track building complexes, has expanded rapidly over the last 5years in China. Over-track building construction has the advantage of comprehensive utilization of land resources, ease of commuting to work, and provide funds for subway construction. But the high frequency of subway operations into and out of the depots can generate excessive vibrations that transmit into the over track buildings, radiate noise within the buildings, hamper the operation of vibration sensitive equipment, and adversely affect the living quality of the building occupants. Field measurements of vibration during subway operations were conducted at Shenzhen, China, a city of 10.62 million people in southern China. Considering the metro depot train testing line and throat area train lines were the main vibration sources, vibration data were captured in five measurement setups. The train-induced vibrations were obtained and compared with limitation of FTA criteria. The structure-radiated noise was calculated using measured vibration levels. The vertical vibration energy directly passed through the columns on both sides of track into the platform, amplifying vibration on the platform by up to 6dB greater than ground levels at testing line area. Vibration amplification around the natural frequency in the vertical direction of over-track building made the peak values of indoor floor vibration about 16dB greater than outdoor platform vibration. We recommend to carefully examining design of new over-track buildings within 40m on the platform over the throat area to avoid excessive vertical vibrations and noise. For both buildings, the measured vertical vibrations were less than the FTA limit. However, it is demonstrated that the traffic-induced high-frequency noise has the potential to annoy occupants on the upper floors. PMID- 27707572 TI - Accumulation of mineral oil saturated hydrocarbons (MOSH) in female Fischer 344 rats: Comparison with human data and consequences for risk assessment. AB - Female Fischer 344 rats were orally exposed to a mixture of mineral oil saturated hydrocarbons (MOSH) of broad molecular mass range at doses of 40, 400 and 4000mg/kg feed. Amounts and compositions of the MOSH were analyzed in liver, spleen, adipose tissue and the carcass after exposure during 30, 60, 90 and 120d as well as after 90d exposure followed by 30d depuration. At 40mg/kg in the feed, after 30d of exposure, 10.9% of the ingested MOSH were recovered from the animal body; after 90d plus 30d depuration it was 3.9%. In liver and spleen, the maximum retention in terms of molecular mass (simulated distillation) was at n-C29; in adipose tissue and carcass it was at n-C15/16. The differentiation between MOSH below and above n-C25 (Class I versus Class II and III oils), used for present regulation, is not supported by the present data on accumulation; structural characteristics seem more pertinent than molecular mass. Concentrations in the tissues increased far less than proportionally with the dose, rendering linear extrapolation to low doses questionable. No steady state was reached after 120d. In fact, comparing with the concentrations in human tissues at the estimated exposure, extrapolation from animal experiments seems to grossly underestimate human internal exposure. Comprehensive two-dimensional gas chromatography (GCxGC) was used to characterize the MOSH residues in the tissues with the aim of identifying the most strongly accumulated types. In the liver and spleen, the highly branched hydrocarbons dominated, whereas in the adipose tissue it was the n-alkanes and species with main n-alkyl moieties. Strong MOSH accumulation is not of concern per se, but the safety at the high concentrations in human tissues needs to be re-evaluated, possibly taking into account also end points other than granuloma formation. PMID- 27707573 TI - Reducing production of taste and odor by deep-living cyanobacteria in drinking water reservoirs by regulation of water level. AB - Abatement and control of algae, producing toxins and creating taste & odor (T&O) in drinking water sources, is a major challenge for water supply. In this study we proposed a strategy based on water level regulation for the control of odor producing cyanobacteria in source water. Miyun Reservoir, the main surface water source for Beijing, has been suffering from 2-methylisoborneol (2-MIB) induced T&O problems caused by deep-living Planktothrix sp. since 2002. The biomass of deep-living Planktothrix in Miyun Reservoir was found to be mainly governed by the water depth above its sediment habitat. An algorithm for water level regulation aiming to minimize the risk for T&O in different types of reservoirs is proposed. The study demonstrates that risk for T&O can be minimized by increasing the water level in Miyun Reservoir. The high-risk area can be reduced by about 2.91% (0.61% to 5.76%) of surface area for each meter increase in the water level, when the water level is lower than 145m. More specifically, the water level needs to be raised to higher than 147.7ma.s.l. from 131.0m in order to obtain an acceptable risk level (ARL) of 10%. This management strategy to abate T&O problems is simpler and cheaper to implement compared to traditional physical, chemical and biological techniques. Moreover, it has no apparent negative impact on water quality and aquatic organisms. PMID- 27707574 TI - Edge effects on N2O, NO and CH4 fluxes in two temperate forests. AB - Forest ecosystems may act as sinks or sources of nitrogen (N) and carbon (C) compounds, such as the climate relevant trace gases nitrous oxide (N2O), nitric oxide (NO) and methane (CH4). Forest edges, which catch more atmospheric deposition, have become important features in European landscapes and elsewhere. Here, we implemented a fully automated measuring system, comprising static and dynamic measuring chambers determining N2O, NO and CH4 fluxes along an edge-to interior transect in an oak (Q. robur) and a pine (P. nigra) forest in northern Belgium. Each forest was monitored during a 2-week measurement campaign with continuous measurements every 2h. NO emissions were 9-fold higher than N2O emissions. The fluxes of NO and CH4 differed between forest edge and interior, but not for N2O. This edge effect was more pronounced in the oak than in the pine forest. In the oak forest, edges emitted less NO (on average 60%) and took up more CH4 (on average 177%). This suggests that landscape structure can play a role in the atmospheric budgets of these climate relevant trace gases. Soil moisture variation between forest edge and interior was a key variable explaining the magnitude of NO and CH4 fluxes in our measurement campaign. To better understand the environmental impact of N and C trace gas fluxes from forest edges, additional and long-term measurements in other forest edges are required. PMID- 27707575 TI - First observations of saturopeaking: Characteristics and implications. AB - During the monitoring of total dissolved gas (TDG) saturation in the Vetlefjordelva River in western Norway in 2014-2015, characteristic waves of supersaturated water were discovered. These waves were significantly correlated with hydropower operation, which was run by hydropeaking (R2=0.82, p<0.001). The TDG saturation varied between 99% and 108%, with a median of 105%. The term "saturopeaking" is introduced for these waves, defined as the artificial, rapid, periodic and frequent fluctuation of gas saturation caused by hydropeaking. Hydropeaking is recognized as hydropower operation that rapidly fluctuates according to the electricity market demand. Though the observed TDG saturation levels were moderate and not likely to cause acute effects on biota, we expect that the observed saturopeaking may have significant ecological impacts in general, especially in cases with TDG saturation levels >110^% which is considered as potentially lethal for fish in rivers. PMID- 27707576 TI - Vulnerability of groundwater resources to nitrate pollution: A simple and effective procedure for delimiting Nitrate Vulnerable Zones. AB - This research was undertaken to further our understanding of the factors involved in nonpoint-source nitrate pollution of groundwater. The shortcomings of some of the most commonly used methods for assessing groundwater vulnerability have been analysed and a new procedure that incorporates key improvements has been proposed. The new approach (LU-IV procedure) allows us to assess and map groundwater vulnerability to nitrate pollution and to accurately delimit the Nitrate Vulnerable Zones. The LU-IV procedure proved more accurate than the most widely used methods to assess groundwater vulnerability (DRASTIC, GOD), when compared with nitrate distribution in the groundwater of 46 aquifers included in the study (using the drainage basin as the unit of analysis). The proposed procedure stands out by meeting the following requirements: (1) it uses readily available parameters that provide enough data to feed the model, (2) it excludes redundant parameters, (3) it avoids the need to assign insufficiently contrasted weights to parameters, (4) it assess the whole catchment area that potentially drains N-polluted waters into the receptor aquifer, (5) it can be implemented within a GIS, and (6) it provides a multi-scale representation. As the LU-IV procedure has been demonstrated to be a reliable tool for delimiting NVZ, it could be particularly interesting to use it in countries where certain types of environmental data are either not available or have only limited availability. Based on this study (and according to the LU-IV procedure), it was concluded that an area of at least 1728km2 should be considered as NVZ. This sharply contrasts with the current 328km2 officially designated in the study area by the Spain's regional administrations. These results highlight the need to redefine the current NVZ designation, which is essential for an appropriate implementation of action programmes designed to restore water quality in line with Directive 91/676/EEC.

PMID- 27707580 TI - Gastric greater curvature plication combined with Nissen fundoplication in the treatment of gastroesophageal reflux disease and obesity. AB - BACKGROUND AND AIM: Established anti-reflux procedures such as fundoplications are less efficient in obese patients. The aim of this study was to investigate clinical effectiveness of the fundoplication combined with gastric greater curvature plication in the treatment of gastroesophageal reflux disease (GERD) in obese patients. MATERIALS AND METHODS: During the period from June 2010 to September 2014, patients operated for GERD with BMI from 30 to 39.9kg/m2 were included into the prospective study. Laparoscopic Nissen fundoplication (LNF, n=58) was performed until February 2013 and later laparoscopic Nissen fundoplication was combined with gastric greater curvature plication (LNFGP, n=56). The groups were compared according to the control of GERD and weight loss. RESULTS: In LNF group there were significantly more males, patients had lower BMI and longer duration of GERD symptoms. Duration of surgery was significantly longer in LNFGP group, 96.5 (17.3)min vs. 59.8 (16.1)min (P<0.0001). Postoperative morbidity was similar, 3.6% and 3.4% in LNFGP and LNF groups, respectively (P=0.9539). The average percentage of excess BMI loss after 12 months was 45.3 (5.8) in LNFGP group as compared to 18.4 (4.6) in LNF group (P<0.0001). Significantly more patients experienced remission or improvement of type 2 diabetes mellitus (P=0.03) and hypercholesterolemia (P=0.0001) in LNFGP group. No significant differences between the groups in postoperative DeMeester score, GERD-HRQL mean score, overall satisfaction and healing of esophagitis were observed. CONCLUSIONS: LNFGP took significantly longer time to perform, but resulted in significantly higher weight reduction and remission/improvement of comorbidities. Both procedures produced similar anti-reflux effect. PMID- 27707581 TI - Comparative Outcome Analysis of Arthroscopic-Assisted Versus Open Reduction and Fixation of Trans-scaphoid Perilunate Fracture Dislocations. AB - PURPOSE: To compare union rates and clinical and radiological outcomes of arthroscopic-assisted reduction and fixation with those of open reduction and fixation in patients with trans-scaphoid perilunate fracture dislocations. METHODS: This retrospective study included consecutive patients with trans scaphoid PLFDs who underwent arthroscopic-assisted reduction and fixation (group A) or open reduction and fixation (group O), and who were followed up for a minimum of 2 years between May 2005 and March 2013. We excluded initially missed patients. Each different surgeon who was on call had performed each experienced operation. These clinical outcomes were assessed: range of motion, grip strength, Mayo wrist score, and Disabilities of Arm, Shoulder, and Hand (DASH) score. For radiologic outcomes, the scapholunate angle, radiolunate angle, and lunotriquetral distance were measured. RESULTS: The total number of included patient was 20 (11 in group A and 9 in group O). Scaphoid union occurred in all patients except 1 individual (11 of 11 in group A, and 8 of 9 in group O). At the last follow-up, the mean flexion-extension arc was significantly greater in group A (125.0 degrees ) than in group O (105.6 degrees ) (P = .028). The mean grip strength was 81.1% that of the contralateral side in group A and 80.9% in group O (P = .594). The mean Mayo wrist score was 85.5 in group A and 79.4 in group O (P = .026), and the mean DASH score was 10.6 in group A and 20.8 in group O (P = .001); however, only the DASH score showed a minimum clinically important difference. The mean scapholunate angle, radiolunate angle, and lunotriquetral distance were similar between the 2 groups: 47.2 degrees , 1.7 degrees , and 2.0 mm in group A and 48.8 degrees , 5.6 degrees , and 2.1 mm in group O, respectively. CONCLUSIONS: Although both arthroscopic and open techniques achieved stability of the injured wrists in patients with trans-scaphoid PLFDs, it is shown that the arthroscopic-assisted technique showed a clinically meaningful better DASH score and greater flexion-extension arc with other parameters being similar. LEVEL OF EVIDENCE: Level III, retrospective comparative study. PMID- 27707582 TI - Time-Dependent Effects of Arthroscopic Conditions on Human Articular Cartilage: An In Vivo Study. AB - PURPOSE: To assess time-dependent effects of arthroscopic conditions on human articular cartilage in vivo. METHODS: From each of 10 patients undergoing multiligament reconstruction of the knee under our routine arthroscopic conditions (gravity irrigation of 0.9% normal saline solution at room temperature with 150 cm H2O [110 mm Hg] pressure and pneumatic tourniquet under 270 mm Hg pressure), cartilage specimens were harvested from the lateral edge of the femoral notch at the beginning of the operation (baseline) and at 15-, 30-, 45-, and 60-minute time points during the operation. H&E staining and safranin O staining were used to evaluate the tissue structure, chondrocytes, and extracellular matrix (ECM) of the articular cartilage. Chondrocyte viability was evaluated, and a biochemical examination of the ECM was performed to detect changes in glycosaminoglycan and collagen content. The expression levels of genes associated with proinflammatory cytokines, ECM metabolism, and chondrocyte apoptosis of the articular cartilage were evaluated. RESULTS: At the 45- and 60 minute time points, an obvious impairment of tissue structure, a significant decrease in glycosaminoglycan content, and a significantly lower percentage chondrocyte viability were observed, as compared with baseline (P < .05). Regarding the tissue collagen content, no significant change was detected at any time point (P > .05). The gene expression examination at the 45- and 60-minute time points detected significant upregulation of interleukin 1beta and tumor necrosis factor alpha (P < .05), indicating an inflammatory response by the chondrocytes, and significant upregulation of aggrecanase 1 (P < .05), which indicates catabolism or the disturbance of aggrecan metabolism. CONCLUSIONS: Under current arthroscopic conditions, an operative duration of 45 minutes or longer can cause detrimental structural, biochemical, and metabolic effects on human articular cartilage. CLINICAL RELEVANCE: Arthroscopic skills should always be improved to reduce operation time and thus minimize the potential detrimental effects of arthroscopic conditions on articular cartilage. PMID- 27707583 TI - Intranasal administration of IL-35 inhibits allergic responses and symptoms in mice with allergic rhinitis. AB - BACKGROUND: IL-35 was recently identified as an anti-inflammatory cytokine. We previously reported that recombinant fusion protein of murine IL-35 and human IgG1 Fc fragment (rIL-35) reduced Th2 cytokines (IL-4 and IL-5) in vitro. However, it is unclear whether IL-35 can attenuate nasal allergic responses and symptoms of allergic rhinitis in vivo. METHODS: To investigate the in vivo effect of IL-35 on allergic rhinitis in mice, mice were sensitized with ovalbumin (OVA). Intranasal administration of rIL-35 and intranasal challenge of OVA were then performed. Nasal symptoms were estimated after the last nasal challenge. Nasal tissue and cervical lymph nodes (CLN) were collected. OVA-specific IgE in sera, OVA-specific T cell response, and the production of cytokines (IL-4, IL-5, and IL 10) stimulated by the OVA antigen were measured. The transcription level of Foxp3 and the frequency of CD4+CD25+ regulatory T cells were also measured. RESULTS: rIL-35 significantly inhibited the number of sneezes and nasal rubbing movements. It also reduced the number of eosinophils in the nasal mucosa and significantly decreased the level of OVA-specific IgE, the OVA-specific T cell proliferation, and the production of IL-4 and IL-5. Furthermore, rIL-35 significantly increased the production of IL-10, the transcription level of Foxp3, and the frequency of CD4+CD25+ regulatory T cells. CONCLUSIONS: This study showed for the first time that rIL-35 inhibits nasal allergic responses and symptoms in mice, and that rIL 35 increases IL-10, Foxp3, and CD4+CD25+ regulatory T cells in CLN. This study also suggests that intranasal administration of IL-35 can attenuate allergic rhinitis. PMID- 27707584 TI - Epithelial-mesenchymal transition in pediatric nephropathies. AB - INTRODUCTION: Epithelial-mesenchymal transition (EMT) is a process in which epithelial cells may express mesenchymal cell markers with subsequent change in their functions, and it may be part of the etiopathogenesis of kidney disease. OBJECTIVE: The aim of this study was to evaluate the immunexpression of some EMT inducers and markers in frequent nephropathies in pediatric patients. METHODS: 59 patients aged 2-18 years old were selected and divided into 6 groups of frequent nephropathies in children and adolescents, as well as one control group. Urea and creatinine data of the patients were recorded. TGF-beta3, fibronectin, alpha-SMA and vimentin were evaluated by immunohistochemistry. RESULTS: Glomerular TGF beta3 was higher in the Lupus Nephritis and Acute Diffuse Glomerulonephritis (ADGN) groups than in the control group. Glomerular fibronectin was higher in the Podocytopathy, Lupus Nephritis, ADGN and Membranous Glomerulopathy patients than in control subjects. The expression of alpha-SMA was higher in the tubulointerstitial compartment of ADGN and Membranous Glomerulopathy groups than in the control group. Glomerular alpha-SMA was higher in ADGN patients than in control and Berger's Disease groups. Glomerular vimentin was higher in individuals with ADGN than in those with Podocytopathy, Lupus Nephritis, Berger's Disease and Thin Basement Membrane Disease/Alport Syndrome. There was a positive correlation between fibronectin in the tubulointerstitial compartment and creatinine levels, between alpha-SMA and vimentin in both tubulointerstitial and glomerular compartments, and between urea and creatinine levels of patients, regardless of their nephropathy (p<0.05 for all results). CONCLUSION: These markers may possibly be used as indicators of renal functional impairment in various nephropathies in pediatric patients.

AB - As pulmonary functional imaging moves beyond the realm of the radiologist and physicist, it is important that imagers have a common language and understanding of the relevant physiology of the lung. This review will focus on key physiological concepts and pitfalls relevant to functional lung imaging. PMID- 27707588 TI - Brain Networks and alpha-Oscillations: Structural and Functional Foundations of Cognitive Control. AB - The most salient electrical signal measured from the human brain is the alpha rhythm, neural activity oscillating at ~100ms intervals. Recent findings challenge the longstanding dogma of alpha-band oscillations as the signature of a passively idling brain state but diverge in terms of interpretation. Despite firm correlations with behavior, the mechanistic role of the alpha-rhythm in brain function remains debated. We suggest that three large-scale brain networks involved in different facets of top-down cognitive control differentially modulate alpha-oscillations, ranging from power within and synchrony between brain regions. Thereby, these networks selectively influence local signal processing, widespread information exchange, and ultimately perception and behavior.

AB - In the last two decades, functional imaging of the lungs using hyperpolarized noble gases has entered the clinical stage. Both helium (3He) and xenon (129Xe) gas have been thoroughly investigated for their ability to assess both the global and regional patterns of lung ventilation. With advances in polarizer technology and the current transition towards the widely available 129Xe gas, this method is ready for translation to the clinic. Currently, hyperpolarized (HP) noble gas lung MRI is limited to selected academic institutions; yet, the promising results from initial clinical trials have drawn the attention of the pulmonary medicine community. HP 129Xe MRI provides not only 3-dimensional ventilation imaging, but also unique capabilities for probing regional lung physiology. In this review article, we aim to (1) provide a brief overview of current ventilation MR imaging techniques, (2) emphasize the role of HP 129Xe MRI within the array of different imaging strategies, (3) discuss the unique imaging possibilities with HP 129Xe MRI, and (4) propose clinical applications.

AB - BACKGROUND: OM-85 is an immunostimulant bacterial lysate, which has been proven effective in reducing the number of lower airways infections. We investigated the efficacy of the bacterial lysate OM-85 in the primary prevention of a murine model of asthma. METHODS: In the first phase of our study the animals received doses of 0.5MUg, 5MUg and 50MUg of OM-85 through gavage for five days (days -10 to -6 of the protocol), 10 days prior to starting the sensitisation with ovalbumin (OVA), in order to evaluate the results of dose-response protocols. A single dose (5MUg) was then chosen in order to verify in detail the effect of OM 85 on the pulmonary allergic response. Total/differential cells count and cytokine levels (IL-4, IL-5, IL-13 and IFN-gamma) from bronchoalveolar lavage fluid (BALF), OVA-specific IgE levels from serum, lung function and lung histopathological analysis were evaluated. RESULTS: OM-85 did not reduce pulmonary eosinophilic response, regardless of the dose used. In the phase protocol using 5MUg/animal of OM-85, no difference was shown among the groups studied, including total cell and eosinophil counts in BALF, serum OVA-specific IgE, lung histopathologic findings and lung resistance. However, OM-85 decreased IL-5 and IL-13 levels in BALF. CONCLUSIONS: OM-85, administered in early life in mice in human-equivalent doses, does not inhibit the development of allergic pulmonary response in mice. PMID- 27707589 TI - Future considerations for clinical dermatology in the setting of 21st century American policy reform: Accountable Care Organizations. AB - An Accountable Care Organization (ACO) is a network of providers that collaborates to manage care and is financially incentivized to realize cost savings while also optimizing standards of care. Since its introduction as part of the 2010 Patient Protection and Affordable Care Act, ACOs have grown to include 16% of Medicare beneficiaries and currently represent Medicare's largest payment initiative. Although ACOs are still in the pilot phase with multiple structural models being assessed, incentives are being introduced to encourage specialist participation, and dermatologists will have the opportunity to influence both the cost savings and quality standard aspects of these organizations. In this article, part of a health care policy series targeted to dermatologists, we review what an ACO is, its relevance to dermatologists, and essential factors to consider when joining and negotiating with an ACO. PMID- 27707591 TI - Impact of skin cancer screening and secondary prevention campaigns on skin cancer incidence and mortality: A systematic review. AB - BACKGROUND: Benefits of skin cancer screening remain controversial. OBJECTIVE: We sought to update evidence on the impact of skin cancer screening and secondary prevention campaigns on skin cancer incidence, mortality, stage-specific incidence, and interval cancers after negative screening. METHODS: We searched MEDLINE and EMBASE for studies published in English or German between January 1, 2005, and February 4, 2015. Two reviewers independently performed study selection, data extraction, and critical appraisal. Results were described in a narrative synthesis. RESULTS: Of 2066 records identified in databases and 10 records found by manual search, we included 15 articles. Overall, evidence suggests that with implementation of skin cancer screening, incidence of in situ and invasive skin cancer increased; increasing rates of thin and decreasing rates of thick melanoma were observed. After cessation of screening, invasive melanoma incidence decreased. A significant melanoma mortality reduction was shown in a German study; 2 other studies observed fewer deaths than expected. No study on interval cancers was identified. LIMITATIONS: Publication bias cannot be ruled out. Most studies are limited because of their ecological design. CONCLUSION: Large ecological studies, a cohort study, a case-control study, and a survey indicate benefits of skin cancer screening, but the evidence level is very low. PMID- 27707590 TI - Development and validation of a noninvasive 2-gene molecular assay for cutaneous melanoma. AB - BACKGROUND: Clinical and histopathologic assessment of pigmented skin lesions remains challenging even for experts. Differentiated and accurate noninvasive diagnostic modalities are highly desirable. OBJECTIVE: We sought to provide clinicians with such a tool. METHODS: A 2-gene classification method based on LINC00518 and preferentially expressed antigen in melanoma (PRAME) gene expression was evaluated and validated in 555 pigmented lesions (157 training and 398 validation samples) obtained noninvasively via adhesive patch biopsy. Results were compared with standard histopathologic assessment in lesions with a consensus diagnosis among 3 experienced dermatopathologists. RESULTS: In 398 validation samples (87 melanomas and 311 nonmelanomas), LINC00518 and/or PRAME detection appropriately differentiated melanoma from nonmelanoma samples with a sensitivity of 91% and a specificity of 69%. We established LINC00518 and PRAME in both adhesive patch melanoma samples and underlying formalin fixed paraffin embedded (FFPE) samples of surgically excised primary melanomas and in melanoma lymph node metastases. LIMITATIONS: This technology cannot be used on mucous membranes, palms of hands, and soles of feet. CONCLUSIONS: This noninvasive 2 gene pigmented lesion assay classifies pigmented lesions into melanoma and nonmelanoma groups and may serve as a tool to help with diagnostic challenges that may be inherently linked to the visual image and pattern recognition approach.

PMID- 27707593 TI - Secukinumab shows significant efficacy in palmoplantar psoriasis: Results from GESTURE, a randomized controlled trial. AB - BACKGROUND: Plaque psoriasis affecting palms and soles is disabling and often resistant to treatment. OBJECTIVE: Evaluate the efficacy and safety of secukinumab, an anti-interleukin 17A antibody, in subjects with palmoplantar psoriasis. METHODS: In this double-blinded, randomized controlled trial, 205 subjects were randomized 1:1:1 to secukinumab 300 mg, 150 mg, or placebo. The primary endpoint was Palmoplantar Investigator's Global Assessment (ppIGA) 0 (clear) or 1 (almost clear/minimal) response at week 16. RESULTS: At week 16, the percentage of subjects who achieved clear or almost clear palms and soles (or ppIGA 0/1) with secukinumab 300 mg (33.3%) and 150 mg (22.1%) was superior to the percentage achieved with placebo (1.5%, P < .001). Palmoplantar Psoriasis Area and Severity Index (ppPASI) was significantly reduced with secukinumab 300 mg ( 54.5%) and 150 mg (-35.3%) compared with placebo (-4.0%, P < .001). Dermatology Life Quality Index (DLQI) 0/1 responses from subjects in the secukinumab groups were also significantly higher compared with placebo at week 16 (P < .01) and pain and function of palms and soles was markedly improved with secukinumab as measured by the palmoplantar Quality-of-Life Instrument. Secukinumab 300 mg consistently showed the best outcomes. The safety profile was favorable and similar to previous studies. LIMITATIONS: Lack of active comparator. CONCLUSION: In GESTURE, the largest randomized controlled trial in palmoplantar psoriasis, secukinumab demonstrated the greatest efficacy to date for treating difficult-to treat psoriasis. PMID- 27707594 TI - The positive impact of radiologic imaging on high-stage cutaneous squamous cell carcinoma management. AB - BACKGROUND: There is limited evidence on the utility of radiologic imaging for prognostic staging of cutaneous squamous cell carcinoma (CSCC). OBJECTIVE: Review utilization of radiologic imaging of high-stage CSCCs to evaluate whether imaging impacted management and outcomes. METHODS: Tumors classified as Brigham and Women's Hospital (BWH) tumor (T) stage T2B or T3 over a 13-year period were reviewed to identify whether imaging was performed and whether results affected treatment. Disease-related outcomes (DRO: local recurrence, nodal metastasis, death from disease) were compared between patients by type of imaging used. RESULTS: 108 high-stage CSCCs in 98 patients were included. Imaging (mostly computed tomography, 79%) was utilized in 45 (46%) patients and management was altered in 16 (33%) patients who underwent imaging. Patients that received no imaging were at higher risk of developing nodal metastases (nonimaging, 30%; imaging, 13%; P = .041) and any DRO (nonimaging, 42%; imaging, 20%; P = .028) compared to the imaging group. Imaging was associated with a lower risk for DRO (subhazard ratio, 0.5; 95% CI 0.2-0.9; P = .046) adjusted for BWH T stage, sex, and location. LIMITATIONS: Single institution retrospective design and changes in technology overtime. CONCLUSIONS: Radiologic imaging of high-stage CSCC may influence management and appears to positively impact outcomes. Further prospective studies are needed to establish which patients benefit from imaging. PMID- 27707596 TI - Modifications of exposure to ambient particulate matter: Tackling bias in using ambient concentration as surrogate with particle infiltration factor and ambient exposure factor. AB - Numerous epidemiological studies explored health risks attributed to outdoor particle pollution. However, a number of these studies routinely utilized ambient concentration as a surrogate for personal exposure to ambient particles. This simplification ignored the difference between indoor and outdoor concentrations of outdoor originated particles and may bias the estimate of particle-health associations. Intending to avoid the bias, particle infiltration factor (Finf), which describes the penetration of outdoor particles in indoor environment, and ambient exposure factor (alpha), which represents the fraction of outdoor particles people are truly exposed to, are utilized as modification factors to modify outdoor particle concentration. In this study, the probabilistic distributions of annually-averaged and seasonally-averaged Finf and alpha were assessed for residences and residents in Beijing. Finf of a single residence and alpha of an individual was estimated based on the mechanisms governing particle outdoor-to-indoor migration and human time-activity pattern. With this as the core deterministic model, probabilistic distributions of Finf and alpha were estimated via Monte Carlo Simulation. Annually-averaged Finf of PM2.5 and PM10 for residences in Beijing tended to be log-normally distributed as lnN( 0.74,0.14) and lnN(-0.94,0.15) with geometric mean value as 0.47 and 0.39, respectively. Annually-averaged alpha of PM2.5 and PM10 for Beijing residents also tended to be log-normally distributed as lnN(-0.59,0.12) and lnN(-0.73,0.13) with geometric mean value as 0.55 and 0.48, respectively. As for seasonally averaged results, Finf and alpha of PM2.5 and PM10 were largest in summer and smallest in winter. The obvious difference between these modification factors and unity suggested that modifications of ambient particle concentration need to be considered in epidemiological studies to avoid misclassifications of personal exposure to ambient particles. Moreover, considering the inter-individual difference of Finf and alpha may lead to a brand new perspective of particle health associations in further epidemiological study. PMID- 27707595 TI - 5-Fr sheathless transradial cardiac catheterization using conventional catheters and balloon assisted tracking; a new approach to downsizing. AB - BACKGROUND: While the uptake of transradial access site is growing, there are concerns about associated radial injury. We report a feasibility study of a technique that enables both 5Fr diagnostic and PCI cases to be undertaken without an arterial sheath using conventional diagnostic and guide catheters with a modified balloon assisted tracking (BAT) technique. METHODS: We performed a prospective single center pilot study to assess the feasibility and effectiveness of sheathless radial artery access and BAT to perform coronary angiography and angioplasty using conventional 5 Fr diagnostic and guide catheters. We assessed for successful acquisition of good quality angiogram, completion of the angioplasty and access site complications. RESULTS: 5 Fr sheathless cardiac catheterization was undertaken in diagnostic (55%) and PCI cases (45%, all indications) in 60 consecutive patients (mean age 62.8+/-11.4years) using conventional catheters. The procedure was successfully performed via the radial artery using a sheathless technique with BAT in 93.3% of patients. All patients had a patent radial artery following removal of the Helix device and there were no recorded access site complications. CONCLUSIONS: Trans-radial cardiac catheterisation for diagnostic and PCI cases using 5F Sheathless catheters (whose outer diameter is smaller than a 3Fr introducer sheath) with BAT appears feasible and allows both cardiac catheterization for diagnostic and PCI indications to be undertaken safely using conventional catheters through the radial route, with high success rates. PMID- 27707597 TI - Patterns of domestic exposure to carbon monoxide and particulate matter in households using biomass fuel in Janakpur, Nepal. AB - Household Air Pollution (HAP) from biomass cooking fuels is a major cause of morbidity and mortality in low-income settings worldwide. In Nepal the use of open stoves with solid biomass fuels is the primary method of domestic cooking. To assess patterns of domestic air pollution we performed continuous measurement of carbon monoxide (CO) and particulate Matter (PM2.5) in 12 biomass fuel households in Janakpur, Nepal. We measured kitchen PM2.5 and CO concentrations at one-minute intervals for an approximately 48-h period using the TSI DustTrak II 8530/SidePak AM510 (TSI Inc, St. Paul MN, USA) or EL-USB-CO data logger (Lascar Electronics, Erie PA, USA) respectively. We also obtained information regarding fuel, stove and kitchen characteristics and cooking activity patterns. Household cooking was performed in two daily sessions (median total duration 4 h) with diurnal variability in pollutant concentrations reflecting morning and evening cooking sessions and peak concentrations associated with fire-lighting. We observed a strong linear relationship between PM2.5 measurements obtained by co located photometric and gravimetric monitoring devices, providing local calibration factors of 4.9 (DustTrak) and 2.7 (SidePak). Overall 48-h average CO and PM2.5 concentrations were 5.4 (SD 4.3) ppm (12 households) and 417.6 (SD 686.4) MUg/m3 (8 households), respectively, with higher average concentrations associated with cooking and heating activities. Overall average PM2.5 concentrations and peak 1-h CO concentrations exceeded WHO Indoor Air Quality Guidelines. Average hourly PM2.5 and CO concentrations were moderately correlated (r = 0.52), suggesting that CO has limited utility as a proxy measure for PM2.5 exposure assessment in this setting. Domestic indoor air quality levels associated with biomass fuel combustion in this region exceed WHO Indoor Air Quality standards and are in the hazardous range for human health. PMID- 27707598 TI - Treatment effects and genotoxicity relevance of the toxic organic pollutants in semi-coking wastewater by combined treatment process. AB - The removal effects of main toxic organic pollutants in semi-coking wastewater by combined treatment process were investigated, while the genotoxicity relevance of wastewater from different treatment units were monitored by using Vicia faba bioassays. Results showed that 37 kinds of toxic organic pollutants were detected in the crude sewage, most of them were removed by physicochemical pretreatment, and the total concentration of organic pollutants decreased from 4826 mg L-1 to 546 mg L-1. After pretreatment, benzenes, phenols, quinolines and indoles in the wastewater were mainly removed by anaerobic/aerobic biodegradation, but the polycyclic aromatic hydrocarbons (PAHs) were removed mainly by advanced treatment, total concentration of toxic organic pollutants was lower than 0.5 mg L-1 in the effluent. Genotoxicity evaluation results showed that the wastewater from coagulating sedimentation unit or foregoing had significant mutagenic properties. However, the micronuclei (MN) frequency (0/00, which was calculated by observing 1000 cells) induced by wastewater after adsorption with modified coke was only 8.060/00, it was no significant difference compared with negative control (7.430/00). It could be concluded that the adsorption treatment was required for the safety of effluent, and the physicochemical-biochemical combined process in this study was suitable for high concentration semi-coking wastewater treatment. PMID- 27707599 TI - Occurrence and trophic magnification of polybrominated diphenyl ethers (PBDEs) and their methoxylated derivatives in freshwater fish from Dianshan Lake, Shanghai, China. AB - In this study, polybrominated diphenyl ethers (PBDEs) and methoxylated polybrominated diphenyl ethers (MeO-PBDEs) were analyzed in eleven freshwater fish species from Dianshan Lake, Shanghai, China. The highest concentrations of PBDEs and MeO-PBDEs were found in snakehead, with mean values of 38 ng g-1 lw and 4.2 ng g-1 lw, respectively. BDE-47 was the predominant congener of PBDEs, followed by BDE-154. Congener pattern variation of PBDEs was observed among different fish species, implying differences in biotransformation potential among fish. Yellow catfish showed highest concentrations of BDE-99, -153 and -183, suggesting that it is more resistant to debromination than any other fish analyzed in the present study. Trophic magnification factors were in the range of 1.35-1.81 for all the PBDE congeners, but not for 2'-MeO-BDE-68. Negative relationship was observed between PBDEs concentration and sample size (length and weight), indicating fish size dilution effect. PMID- 27707600 TI - Transfer of hexabromocyclododecane flame retardant isomers from captive American kestrel eggs to feathers and their association with thyroid hormones and growth. AB - Feathers are useful for monitoring contaminants in wild birds and are increasingly used to determine persistent organic pollutants. However, few studies have been conducted on birds with known exposure levels. We aimed to determine how well nestling feather concentrations reflect in ovo exposure to hexabromocyclododecane (alpha-, beta- and gamma-HBCDD), and to determine if feather concentrations are related to physiological biomarkers. Captive kestrels (n = 11) were exposed in ovo to maternally transferred HBCDD-isomers at concentrations of 127, 12 and 2 ng/g wet weight of alpha-, beta- and gamma-HBCDD (measured in sibling eggs), respectively, and compared to controls (n = 6). Nestling growth was monitored at 5 d intervals and circulating thyroid hormone concentrations assessed at d 20. Tail feathers were collected prior to the first molt and analyzed for HBCDD isomers. The mean SigmaHBCDD concentration in feathers was 2405 pg/g dry weight (in exposed birds) and alpha-, beta- and gamma HBCDD made up 32%, 13%, and 55%, respectively of the SigmaHBCDD concentrations. This isomer distribution deviated from the typical dominance of alpha-HBCDD reported in vertebrate samples. Exposed chicks had significantly higher feather concentrations of beta- and gamma-HBCDD compared with controls (p = 0.007 and p = 0.001 respectively), while alpha-HBCDD concentrations did not differ between the two groups. Feather concentrations of alpha-HBCDD were best explained by egg concentrations of beta- or gamma-HBCDD concentrations (wi = 0.50, 0.30 respectively), while feather concentrations of beta- and gamma-HBCDD were influenced by growth parameters (rectrix length: wi = 0.61; tibiotarsus length: wi = 0.28). These results suggest that feather alpha-HBCDD concentrations may reflect internal body burdens, whereas beta- and gamma-HBCDD may be subject to selective uptake. The alpha-HBCDD concentrations in the feathers were negatively associated with the ratio of plasma free triiodothyronine to free thyroxine (T3:T4; p = 0.020), demonstrating for the first time that feather concentrations may be used to model the effect of body burdens on physiological endpoints. PMID- 27707601 TI - The level of mercury contamination in mariculture sites at the estuary of Pearl River and the potential health risk. AB - In the present study, the Hg contamination in mariculture sites located at the estuary of Pearl River was to investigate with an attempt to analyse associated health risks of dietary exposure to both total mercury (THg) and methyl mercury (MeHg) in cultured fish and shellfish. The highest total mercury concentration (7.037 +/- 0.556 ng L-1) of seawater was observed at Zhuhai Estuary. The Hg concentrations of sediment in Guishan Island were significantly higher (p < 0.05) than in Daya Bay (away from the Pearl River). Besides, the both THg and MeHg levels in sediment at mariculture sites were higher (p < 0.05) than corresponding reference sites. It was attributed to the fact that mariculture activities increased Hg loading and promoted MeHg production. The vertical distribution of Hg in sediment cores demonstrated that mercury methylation mostly occurred at the sediment-water interface. Results of health risk assessments showed that fish consumption would impose a higher risk to children but less to adults, while shellfish produced in the studied area was safe for consumption. PMID- 27707603 TI - Recent progress on the discovery of antiamoebic agents. AB - A large number of protozoans infect humans but Entamoeba histolytica is the only organism responsible for causing amoebiasis, a deadly disease after malaria. Numerous heterocycle-based antiamoebic agents have been previously synthesized as E. histolytica inhibitors and while some of these agents have shown moderate activity, the search for a novel and ideal antiamoebic compound is still ongoing. In this digest Letter, we present the latest data on antiamoebic agents from 2011 to 2016 based on the different classes of heterocyclic agents. PMID- 27707602 TI - Effects of mineral amendments on trace elements leaching from pre-treated marine sediment after simulated rainfall events. AB - Bauxite extraction by-products (red mud) were used to evaluate their potential ability to stabilize trace elements from dredged and aerated/humidified marine sediment. The investigated by-products were: bauxaline(r)(BX) that is a press filtered red mud; bauxsolTM(BS) that is a press-filtered red mud previously washed with excess of seawater, and gypsum neutralized bauxaline(r) (GBX). These materials were separately mixed to dredged composted sediment sample considering 5% and 20% sediment: stabilizer ratios. For pilot experiments, rainfall events were regularly simulated for 3 months. Concentrations of As, Mo, Cd, Cr, Zn, Cu, and Ni were analyzed in collected leachates as well as toxicity. Results showed that Cd, Mo, Zn, and Cu were efficiently stabilized in the solid matrix when 20% of BX, BS, and GBX was applied. Consequently, toxicity of leachates was lower than for the untreated sediment, meaning that contaminants mobility was reduced. A 5% GBX was also efficient for Mo, Zn and Cu stabilization. In all scenarios, As stabilization was not improved. Compared to all other monitored elements, Mo mobility seemed to depend upon temperature-humidity conditions during pilot experiments suggesting the need of further investigations. PMID- 27707604 TI - Synthesis and biological evaluation of ricinoleic acid-based lipoamino acid derivatives. AB - A series of novel ricinoleic acid based lipoamino acid derivatives were synthesized from (Z)-methyl-12-aminooctadec-9-enoate and different l-amino acids (glycine, alanine, phenyl alanine, valine, leucine, isoleucine, proline and tryptophan). The structures of all the prepared compounds were characterized by 1H NMR, 13C NMR and mass spectral studies. The title compounds were evaluated for their antimicrobial and anti-biofilm activities. Among all the derivatives, compound 7a (Z)-methyl-12-(2-aminoacetamido)octadec-9-enoate exhibited promising antibacterial activity (MIC, 3.9-7.8MUg/mL) and compounds 7b (Z)-methyl 12-(2 aminopropanamido)octadec-9-enoate and 7g (Z)-methyl-12-(pyrrolidine-2 carboxamido)octadec-9-enoate exhibited moderate activity (MIC, 7.8-31.2MUg/mL) selectively against four different Gram-positive bacterial strains such as Staphylococcus aureus MTCC 96, Bacillus subtilis MTCC 121, S. aureus MLS-16 MTCC 2940, Micrococcus luteus MTCC 2470. These compounds also exhibited excellent antifungal activity against studied fungal strains. Further, the compounds 7a, 7b and 7g were also screened for anti-biofilm activity. Among these lipoamino acid derivatives, compound 7a exhibited good anti-biofilm activity (IC50, 1.9 4.1MUg/mL) against four Gram-positive bacterial strains.

PMID- 27707605 TI - Cyclic peptide-based potent and selective SIRT1/2 dual inhibitors harboring Nepsilon-thioacetyl-lysine. AB - In the current study, we discovered that several N-terminus-to-side chain cyclic tripeptides harboring the catalytic mechanism-based SIRT1/2/3 inhibitory warhead Nepsilon-thioacetyl-lysine at their central positions exhibited a comparably strong inhibition (nM level) against the SIRT1/2-catalyzed Nepsilon-acetyl-lysine deacetylation reactions. Their dual SIRT1/2 inhibitory action was also found to be stronger than that against SIRT3/5/6. Considering the previous demonstration that a SIRT1/2 dual inhibition could be instrumental in achieving an anti-cancer effect on those cancers retaining the wild-type tumor suppresser p53 protein, these compounds could be employed as leads for developing novel anti-cancer agents. PMID- 27707607 TI - Association between acute kidney injury and risk of Parkinson disease. AB - BACKGROUNDS: Worldwide, the incidence of acute kidney injury (AKI) has been increasing. However, information on the long-term incidence of Parkinson disease (PD) in patients with AKI has not been reported. METHODS: A total of 9380 patients with AKI and 37,484 age- and sex-matched patients who did not have AKI were identified during 2003-2011. All patients were tracked until a diagnosis of PD, death, or the end of 2011. Cumulative incidences and hazard ratios (HRs) were calculated. RESULTS: The mean follow-up time for PD was 6.89 (SD=3.30) years in the AKI cohort and 6.78 (SD=3.29) years in the non-AKI cohort. The overall incidence densities of PD were significantly higher in the AKI cohort than in the non-AKI cohort (6.04 vs. 3.99/1000 person-years), with an adjusted HR of 1.47 (95% confidence interval [CI]=1.18-1.83). Compared with the patients in the non AKI cohort aged <=64years, the relative risk (95% CI) of PD was 2.17 (1.12-4.18), 14.1 (9.16-21.8), and 14.1 (8.43-23.6) for the patients in the AKI cohort aged <=64, 65-79, and >=80years, respectively. CONCLUSION: Patients with AKI were associated with a higher long-term risk of PD. PMID- 27707609 TI - The Treatment of Plasmodium knowlesi Malaria. AB - Plasmodium knowlesi occurs across Southeast Asia and is the most common cause of malaria in Malaysia. High parasitaemias can develop rapidly, and the risk of severe disease in adults is at least as high as in falciparum malaria. Prompt initiation of effective treatment is therefore essential. Intravenous artesunate is highly effective in severe knowlesi malaria and in those with moderately high parasitaemia but otherwise uncomplicated disease. Both chloroquine and artemisinin-combination therapy (ACT) are highly effective for uncomplicated knowlesi malaria, with faster parasite clearance times and lower anaemia rates with ACT. Given the difficulties with microscope diagnosis of P. knowlesi, a unified treatment strategy of ACT for all Plasmodium species is recommended in coendemic regions. PMID- 27707608 TI - CHA2DS2-VASc score and clinical outcomes of patients with acute coronary syndrome. AB - BACKGROUND: The CHA2DS2-VASc score has been recommended for the assessment of thromboembolic risk in patients with atrial fibrillation. HYPOTHESIS: The CHA2DS2 VASc score may be associated with adverse outcomes in patients with ACS. METHODS: Included were patients with ACS enrolled in the Acute Coronary Syndrome Israeli biennial Surveys (ACSIS) during 2000-2013. Patients were divided into 4 groups according to their CHA2DS2-VASc score (0 or 1, 2 or 3, 4 or 5, and >5). The primary endpoint was 1-year all-cause mortality. RESULTS: The 13,422 patients had a mean age of 63.5+/-13years and included 25.8% females. Higher CHA2DS2-VASc score was associated with a significant increase in 1-year mortality. Patients with a CHA2DS2-VASc score >5 had the highest 1-year mortality risk that was 6 fold higher compared to patients with a score of 0 to 1 (hazard ratio=6, 95% CI=4.1-8.8, p<0.0001). However, even an intermediate CHA2DS2-VASc score of 2-3 was associated with a significant 2.6-fold increase in 1-year mortality. Patients with a higher CHA2DS2-VASc score were less frequently selected for an invasive strategy with an early coronary angiogram and subsequent angioplasty and were less commonly treated with the guideline-based medications. However, differences in outcomes remained significant following a multivariate analysis suggesting that these variations in therapy can only partially explain the differences in outcomes. CONCLUSIONS: Higher CHA2DS2-VASc score identifies high-risk patients that may be overlooked by existing scores. Further studies are needed in order to evaluate whether the CHA2DS2-VASc score may be used together with the GRACE score for an improved risk assessment of ACS patients. PMID- 27707610 TI - Aberrant expressions of stem cell factor/c-KIT in rat testis with varicocele. AB - BACKGROUND/PURPOSE: Varicocele (VC) is considered by the World Health Organization as the main cause of male infertility. Studies have shown that VC can affect spermatogenesis and then result in male infertility. But the exact mechanism by which VC affects spermatogenesis is still unclear. Stem cell factor (SCF) and c-KIT receptor are crucial molecules during spermatogenesis in testis. This study aims to investigate whether SCF/c-KIT signaling is involved in the pathophysiology of VC on spermatogenesis. METHODS: Rat models of VC were built (n = 13), and sham-operated rats were used as controls (n = 8). The seminiferous tubules of the testis were observed with hematoxylin and eosin staining, expression of SCF was analyzed via enzyme-linked immunosorbent assay and Western blot, and expression of c-KIT was assessed with Western blot and immunofluorescence. RESULTS: Compared with controls, the seminiferous epithelium was disorganized and had significantly fewer cells in the testes of rats with VC. Expression of SCF increased in testes of VC rats, while expression of c-KIT was decreased. CONCLUSION: These results suggest that sperm counts in seminiferous epithelium are affected by VC, and the SCF/c-KIT system is aberrantly expressed in VC testis, which could be involved in male infertility caused by VC.

AB - The existing data demonstrate a significant interrelation between ASD and essential and toxic trace elements status of the organism. However, data on trace element homeostasis in particular ASD forms are insufficient. Therefore, the objective of the present study was to assess the level of trace elements and electrolytes in serum of children with childhood and atypical autism. A total of 48 children with ASD (24 with childhood and 24 with atypical autism) and age- and sex-adjusted controls were examined. Serum trace elements and electrolytes were assessed using inductively-coupled plasma mass spectrometry. The obtained data demonstrate that children with ASD unspecified are characterized by significantly lower Ni, Cr, and Se levels as compared to the age- and sex-matched controls. At the same time, significantly decreased serum Ni and Se concentrations were detected in patients with childhood autism. In turn, children with atypical autism were characterized by more variable serum trace element spectrum. In particular, atypical autism is associated with lower serum Al, As, Ni, Cr, Mn, and Se levels in comparison to the control values. Moreover, Al and Mn concentration in this group was also lower than that in childhood autism patients. Generally, the obtained data demonstrate lower levels of both essential and toxic trace elements in atypical autism group, being indicative of profound alteration of trace elements metabolism. However, further detailed metabolic studies are required to reveal critical differences in metabolic pathways being responsible for difference in trace element status and clinical course of the disease. PMID- 27707612 TI - Prevalence of treatment-resistant hypertension and important associated factors results from the Swedish Primary Care Cardiovascular Database. AB - We aimed to describe the prevalence, treatment, and associated comorbidity of treatment-resistant hypertension (TRH). This registry-based cohort study from The Swedish Primary Care Cardiovascular Database assessed 53,090 hypertensive patients attending primary care. Patients adherent to antihypertensive treatment measured by pharmacy fills and with proportion of days covered >=80% were included. The prevalence of TRH was 17% when considering all current TRH definitions. Adherence to mineralocorticoid receptor antagonists differed between TRH- and non-TRH patients (8 vs. 4%). Higher frequencies (prevalence ratio and 95% confidence intervals) of diabetes mellitus (1.59, 1.53-1.66), heart failure (1.55, 1.48-1.64), atrial fibrillation (1.33, 1.27-1.40), ischemic heart disease (1.25, 1.20-1.30), and chronic kidney disease (1.38, 1.23-1.54) were seen in patients with TRH compared to patients without TRH. These findings, in a population with valid data on medication adherence, emphasize a broad preventive approach for these high-risk patients. PMID- 27707613 TI - Post-traumatic transient cortical blindness in a child with occipital bone fracture. AB - Cortical blindness as sequelae of trauma has been reported in literature but mostly in the setting of occipital cortex or visual tract damages. We present a case of transient cortical blindness in a child following a closed head injury with a non-displaced occipital bone fracture and underlying occipital lobe contusion. We discuss the pathophysiology behind Post-traumatic transient cortical blindness, relevant investigations, and current management. PMID- 27707614 TI - Extreme lateral interbody fusion relieves symptoms of spinal stenosis and low grade spondylolisthesis by indirect decompression in complex patients. AB - Spinal stenosis and low-grade spondylolisthesis produce symptoms of neural compression that can be treated with extreme lateral lumbar interbody fusion (XLIF) via indirect decompression. This study aimed to investigate whether the restoration of disc dimensions would relieve symptoms of radiculopathy, claudication and back pain. In this retrospective study, patients undergoing XLIF surgery for relief of radicular symptoms or degenerative disc disease were included. Radiologically proven changes were used to assess the modes of degeneration. Objective measures such as the Visual Analogue Scale (VAS) for back and legs and the Oswestry Disability Index (ODI) were used. Complications were collated post-operatively from clinical notes and outpatient appointments. Twenty three consecutive patients were included, of whom 91% had spinal stenosis. The cohort presented with multiple comorbidities and 35% of the cohort had undergone previous lumbar surgery. There was a 61% improvement of coronal Cobb angle and an 11% correction of the lordosis sustained 1year after surgery. Clinical outcomes at 1year showed 39%, 50% and 60% improvements in the ODI, back and leg VAS scores respectively. 48% of patients had reduced sensation related to lumbosacral plexus manipulation and one retroperitoneal haematoma was conservatively managed. Minimally invasive spinal (MIS) XLIF resulted in effective restoration of disc dimensions via indirect decompression, providing good relief of clinical symptoms evidenced by significant improvement in clinical outcome scores. XLIF corrected scoliosis and improved lumbar lordosis significantly. Several plexopathies did not hinder long-term recovery. XLIF is highly suited to treating complex patients with multiple comorbidities and degenerative disease. PMID- 27707615 TI - Prospective controlled cohort study of Troponin I levels in patients undergoing elective spine surgery for degenerative conditions: Prone versus supine position. AB - : Prior studies have suggested that elevated serum Troponin-I (TnI) levels immediately after non-cardiac surgical procedures (8-40%) represent subclinical cardiac stress which independently predicts increased 30-day mortality. Routine post-operative TnI monitoring has therefore been suggested as a standard of care. However, no prior studies have focussed on elective degenerative spine surgery, whilst few have measured pre-op TnI. Further, prolonged prone positioning could represent an additional, independent, cardiac stress. We planned a prospective controlled cohort study of consecutive TnI levels in routine elective spine surgery for degenerative spine conditions, incorporating 3 groups: 'prone<2h', 'prone>2h' and 'supine' positioning. TnI levels (>0.04MUg/L) were recorded immediately pre-/post-surgery, and by 24h of surgery. N=120 patients were recruited. Complete results were obtained in 92 (39 supine, 53 prone). No significant between-groups differences were observed in demographic or cardiovascular risk factors. Validated TnI-elevation by 24h was not observed in any group. Spurious elevations were recorded in one 'prone<2h' and one 'prone>2h'. One non-ST segment myocardial infarction (STEMI) occurred on day 7 without TnI elevation by 24h (prone>2h). There was no 30-day mortality. CONCLUSIONS: Despite a lower cut-off, no validated TnI elevation was observed in any group by 24h after surgery. One non-STEMI had not been associated with TnI elevation by 24h. Immediately peri-operative cardiac stress therefore appeared comparatively rare in patients undergoing routine elective spine surgery. Further, prone positioning did not represent an additional, independent, risk. Routine immediately post-operative TnI monitoring in elective spine surgery therefore appears unjustified. Our study highlighted several caveats regarding consecutive TnI testing. PMID- 27707616 TI - Potential action of extract of Acmella oleracea (L.) R.K. Jansen to control Amblyomma cajennense (Fabricius, 1787) (Acari: Ixodidae) ticks. AB - The use of synthetic acaricides is currently the main method to control ticks. However, the indiscriminate use of these chemicals can lead to the selection of resistant individuals and in the accumulation of chemical residues in the environment, contaminating the soil and water streams, consequently affecting the flora, fauna, and the human beings as well. In this sense, the objective of this study was to investigate the acaricidal effect of crude ethanolic extract of Acmella oleracea (L.) R.K. Jansen aerials parts at different concentrations on fed males and semi-engorged females of A. cajennense s.s. An in vitro bioassay (Adult Immersion Test) was carried out to determine the lethal concentration 50 (LC50) of ethanolic extract, calculated by Probit analysis. The results showed that the fed males were sensitive to all the concentrations of A. oleracea ethanolic extract, and mortality rate progressively increased (15-65%) in higher ethanolic extract concentrations. However, semi-engorged females were not sensitive to all the concentrations used here. In the highest concentration (100mg/mL), a mortality rate of 100% was observed after 72h of exposure, indicating that the acaricidal effect would probably be dose-dependent. The LC50 values obtained for the fed A. cajennense s.s males and semi-engorged females were 29.4534mg/mL (limits: 24.4467-41.3847mg/mL) and LC50=17.6335mg/mL (limits: 5.2506-23.5335mg/mL), respectively. PMID- 27707617 TI - Stenting versus endarterectomy after prior ipsilateral carotid endarterectomy. AB - BACKGROUND: Restenosis after carotid endarterectomy (CEA) is associated with an increased risk of stroke, and the management of critical or symptomatic restenotic lesions poses a treatment challenge. The superiority of CEA vs carotid angioplasty and stenting (CAS) for restenosis remains debatable because existing studies are few and limited by small sample size or the inability to align interventions with ipsilateral events beyond the periprocedural period. We performed a population-based evaluation of CEA vs CAS in a large contemporary cohort of patients with carotid artery restenosis. METHODS: We studied all patients in the Vascular Quality Initiative (VQI) database who underwent CEA or CAS after prior ipsilateral CEA between January 2003 and April 2015. Univariate methods (chi2 and t-test) were used to compare patients' characteristics and outcomes <=30 days and up to 1 year. Multivariate logistic and Cox regression analyses, adjusting for patients' demographic and clinical characteristics, were used to compare the procedures with respect to ipsilateral stroke, death, myocardial infarction (MI), stroke/death, and stroke/death/MI. RESULTS: This cohort of patients with prior ipsilateral CEA underwent 2863 carotid interventions, 1047 (37%) CEA, and 1816 (63%) CAS. Characteristics were similar in both groups. The 30-day ipsilateral stroke rate comparing CEA vs CAS was 2.2% vs 1.3% (P = .09) for asymptomatic patients and 1.2% vs 1.6% (P = .604) for symptomatic patients. The 30-day mortality was 1.3% vs 0.6% (P = .04), and MI occurred in 1.4% of CEA vs 1.1% of CAS patients (P = .443). Cranial nerve injury occurred in 4.1% of the redo-CEA cases, and access site complications occurred in 5.3% of the CAS cases. CEA was associated with higher mortality at 30 days (adjusted odds ratio [aOR], 2.83; 95% confidence interval [CI], 1.13-7.14; P = .027) and at 1 year (adjusted hazard ratio, 2.17; 95% CI, 1.03-4.58; P = .042). However, there were no differences in postoperative stroke (aOR, 0.54; 95% CI, 0.20-1.45, P = .22), MI (aOR, 0.98; 95% CI, 0.31-3.10; P = .97), stroke/death (aOR, 1.38; 95% CI, 0.72-2.67; P = .22), and stroke/death/MI (aOR, 1.38; 95% CI, 0.80-2.37; P = .25) between CEA and CAS after adjusting for patient characteristics, and freedom from stroke at 1 year was also similar (CEA: 96.7% vs CAS: 96.4%; P = .78). CONCLUSIONS: In this population-based study, we have shown higher mortality but similar stroke and MI associated with redo CEA compared with CAS after prior ipsilateral CEA. We recommend avoidance of redo CEA in very sick patients. Smoking cessation remains a potent target for improvement of outcomes of carotid revascularization in these patients. PMID- 27707618 TI - Insight into the cerebral hyperperfusion syndrome following carotid endarterectomy from the national Vascular Quality Initiative. AB - BACKGROUND: Cerebral hyperperfusion syndrome (CHS), characterized by severe ipsilateral headache, seizures, and intracranial hemorrhage, is a rare, poorly understood complication that can be fatal following carotid endarterectomy (CEA). The purpose of the study was to determine the factors associated with CHS as captured in the Vascular Quality Initiative. METHODS: Analysis was conducted on 51,001 procedures captured from the CEA module of the Vascular Quality Initiative from 2003 to 2015. Preoperative, operative, and postoperative variables were considered for inclusion in logistic regression analyses to determine possible associations with CHS. The relative contribution of each variable to the overall model was determined using dominance analysis. RESULTS: The mean age was 70.2 +/- 9.4 years; there were 39.6% female patients, 93.1% of white race, with 29.6% of CEAs being performed for symptomatic status. The overall rate of CHS was 0.18% (n = 94), with 55.1% occurring in asymptomatic and 44.9% occurring in symptomatic patients with an associated mortality rate of 38.2%. Multivariable analysis including preoperative variables showed that female gender (odds ratio [OR], 1.65; 95% confidence interval [CI], 1.09-2.51; P = .019), <1 month major ipsilateral stroke (OR, 5.36; 95% CI, 2.35-12.22; P < .001), coronary artery disease (OR, 1.77; 95% CI, 1.15-2.71; P = .009), and contralateral stenosis >=70% (OR, 1.54; 95% CI, 1.00-2.36; P = .050) were independently associated with CHS and that <1 month major stroke was the most important contributor to the model. With the additional inclusion of operative and postoperative variables, female gender (OR, 1.75; 95% CI, 1.14-2.67; P = .010), <1 month ipsilateral major stroke (OR, 3.20; 95% CI, 1.32-7.74; P = .010), urgency (OR, 2.25; 95% CI, 1.38-3.67; P = .001), re-exploration (OR, 2.98; 95% CI, 1.27-6.97; P = .012), postoperative hypertension (OR, 4.09; 95% CI, 2.65-6.32; P < .001), postoperative hypotension (OR, 3.21; 95% CI, 1.97-5.24; P < .001), dysrhythmias (OR, 3.23; 95% CI, 1.64 6.38; P = .001), and postoperative myocardial infarction (OR, 2.84; 95% CI, 1.21 6.67; P = .017) were significantly associated with CHS, with postoperative blood pressure lability and cardiac complications having the strongest associations with CHS. CONCLUSIONS: The risk of CHS was highest in female patients and in those with a recent major stroke, coronary artery disease, and contralateral stenosis >=70%. In addition, in adjusting for operative and postoperative variables, CHS was most significantly associated with postoperative blood pressure lability and cardiac complications. These data lend insight into a high risk population for this devastating complication. PMID- 27707619 TI - Single-center results of a series of prosthetic axillary-axillary arteriovenous access grafts for hemodialysis. AB - OBJECTIVE: Prosthetic infraclavicular axillary-axillary arteriovenous access grafts are one of a number of complex dialysis access options in patients when all of the usual upper limb possibilities have been exhausted. We present a follow-up of 35 patients who received this access graft during a 9-year period. METHODS: Patients were identified from our own operation records. Follow-up data were gathered from their locally held electronic medical records. Primary and secondary patency were calculated using the Kaplan-Meier estimate. RESULTS: During the study period, 15 of the 35 patients in our cohort underwent one or more revision operations. Primary patency was estimated at 88% at 6 months, and the secondary patency rate estimate was 54% at 48 months. Twelve patients died during the study period; the grafts in 17 of the 23 remaining patients were in use at the conclusion of the study. CONCLUSIONS: Although this is a small cohort, our results suggest that prosthetic axillary-axillary arteriovenous access should be at least considered as a viable long-term option for hemodialysis patients. PMID- 27707620 TI - Management of patients with acute aortic syndrome through a regional rapid transport system. AB - OBJECTIVE: The objective of this study was to describe the outcomes of patients with acute aortic syndrome (AAS) during and after transfer to a regional aortic center by a rapid transport system. METHODS: Review of patients with AAS who were transferred by a rapid transport system to a regional aortic center was performed. Data regarding demographics, diagnosis, comorbidities, transportation, and hospital course were acquired. Severity of existing comorbidities was determined by the Society for Vascular Surgery Comorbidity Severity Score (SVSCSS). The Acute Physiology and Chronic Health Evaluation II (APACHE II) score assessed physiologic instability on admission. Risk factors associated with system-related (transfer and hospital) mortality were identified by univariate and multivariate linear regression analysis. RESULTS: During a recent 18-month period (December 2013-July 2015), 183 patients were transferred by a rapid transport system; 148 (81%) patients were transported by ground and 35 (19%) by air. Median distance traveled was 24 miles (range, 3.6-316 miles); median transport time was 42 minutes (range, 10-144 minutes). Two patients died during transport, one with a type A dissection, the other of a ruptured abdominal aortic aneurysm. There were 118 (66%) patients who received operative intervention. Median time to operation was 6 hours. Type B dissections had the longest median time to operation, 45 hours, with system-related mortality of 1.9%; type A dissections had the shortest median time, 3 hours, and a system-related mortality of 16%. Overall, system-related mortality was 15%. On univariate analysis, factors associated with system-related mortality were age >=65 years (P = .026), coronary artery disease (P = .030), prior myocardial infarction (P = .049), prior coronary revascularization (P = .002), SVSCSS of >8 (P < .001), abdominal pain (P = .002), systolic blood pressure <90 mm Hg at sending hospital (P = .001), diagnosis of aortic aneurysm (P = .013), systolic blood pressure <90 mm Hg in the intensive care unit (P < .001), and APACHE II score >10 (P = .004). Distance traveled and transport mode and duration were not associated with increased risk of system-related mortality. Only SVSCSS of >8 (odds ratio, 7.73; 95% confidence interval, 2.32-25.8; P = .001) was independently associated with an increase in system-related mortality on multivariate analysis. CONCLUSIONS: Implementation of a rapid transport system, regardless of mode or distance, can facilitate effective transfer of patients with AAS to a regional aortic center. An SVSCSS of >8 predicted an increased system-related mortality and may be a useful metric to assess the appropriateness of patient transfer. PMID- 27707622 TI - Discussion. PMID- 27707621 TI - Predictors of intervention and mortality in patients with uncomplicated acute type B aortic dissection. AB - OBJECTIVE: Patients with uncomplicated acute type B aortic dissection (uATBAD) have historically been managed with medical therapy. Recent studies suggest that high-risk patients with uATBAD may benefit from thoracic endovascular aortic repair. This study aims to determine the predictors of intervention and mortality in patients with uATBAD. METHODS: All patients admitted with uATBAD from 2000 to 2014 were reviewed, and those with computed tomographic angiography imaging were included. Multiplanar reconstruction was used to obtain double orthogonal oblique measurements. All measurements were obtained by a specialized cardiovascular radiologist (D.O.). The maximum aortic diameter, proximal descending thoracic aorta false lumen (FL) diameter, and area were recorded. Outcomes, including the need for intervention and mortality, were tracked over time. Data were analyzed by stratified Kaplan-Meier and multiple Cox regression analysis using SAS v 9.4 (SAS Institute, Cary, NC). RESULTS: During the study period, 294 patients with uATBAD were admitted with 156 having admission computed tomographic angiography imaging available for analysis. The cohort had an average age of 60.6 years (+/ 13.6 years); 60% were males. The average follow-up time was 3.7 years (interquartile range, 2.1-6.9). A stratified analysis demonstrated the most sensitive cutoff for mortality was aortic diameter >44 mm (P < .01), and it appeared to be a threshold effect with minimal additional information added by finer size stratification. FL diameter did not predict mortality in our series (P = .36). Intervention-free survival, alternatively, appeared to decrease over the range of diameters from 35 to 44 mm (P < .01). An FL diameter >22 mm was associated with decreased intervention-free survival (P < .04). Age >60 years on admission also demonstrated decreased survival compared with those <=60 years of age (P < .01). Diameter >44 mm persisted as a risk factor for mortality (hazard ratio, 8.6; P < .01) after adjustment for diabetes (6.7; P < .01), age (1.06/y; P < .01), history of stroke (5.4; P < .01), connective tissue disorder (2.3; P < .01), and syncope on admission (9.5; P < .04). The 1-, 5-, and 10-year intervention rate for patients with admission aortic diameter >44 mm was 18.8%, 29.5%, and 50.3%, respectively, compared with 4.8%, 13.3%, and 13.3% in the <=44 mm group (P < .01). CONCLUSIONS: Aortic diameter >44 mm is a predictor of mortality after adjustment for other significant risk factors. Age >60 years on admission is a predictor of mortality. An FL diameter >22 mm as well as those with maximum aortic diameter >44 mm on admission were associated with decreased intervention-free survival. Patients with these high-risk criteria may benefit from thoracic endovascular aortic repair. Further studies are needed to further define those patients at highest risk and, thus, most likely to benefit from early intervention. PMID- 27707623 TI - Triethylated chromones with substituted naphthalenes as tubulin inhibitors. AB - Previously synthesized 2-(benzo[b]thiophene-3'-yl)-6,8,8-triethyldesmosdumotin B (1, TEDB-TB) and 2-(naphth-1'-yl)-6,8,8-triethyldesmosdumotin B (2) showed potent activity against multiple human tumor cell lines, including a multidrug-resistant (MDR) subline, by targeting spindle formation and/or the microtubule network. Consequently, ester analogues of hydroxylated naphthyl substituted TEBDs (3-5) were prepared and evaluated for their effects on tumor cell proliferation and on tubulin assembly. Among all new compounds, compound 6, a 4'-acetoxynaphthalen-1' yl derivative, displayed the most potent antiproliferative activity (IC50 0.2 5.7MUM). Selected analogues were confirmed to be tubulin assembly inhibitors in cell-free and cell-based assays using MDR tumor cells. The new analogues partially inhibited colchicine binding to tubulin, suggesting their binding mode would be different from that of colchicine. This observation was supported by computational docking model analyses. Thus, the newly synthesized triethylated chromones with esterified naphthalene groups have good potential for development as a new class of mitotic inhibitors that target tubulin. PMID- 27707624 TI - Methylene versus carbonyl bridge in the structure of new tubulin polymerization inhibitors with tricyclic A-rings. AB - The phenothiazine group has been identified as a suitable A ring in the structure of tubulin polymerization inhibitors. In our search to identify more potent inhibitors, a study of different isosteric tricyclic groups as new potential A rings was first realized and permitted to identify 1-azaphenothiazine and iminodibenzyl as favorable modulations providing compounds with improved activity against tubulin. An investigation of the methylene group as the connector between the A and B rings revealed that the "CH2" bridge was tolerated, improving the biological potency when the A unit was of phenothiazine, 1-azaphenothiazine or iminodibenzyl type. Molecules 6-8 and 12 showed increased biological activity in comparison to parent phenstatin 2 on COLO 205 colon cancer cell line. The most antineoplastic agent in the current study was phenothiazine 5 displaying a GI50 of 25nM against the melanoma MDA-MB-435 cell line. PMID- 27707625 TI - Synthesis and topoisomerases inhibitory activity of heteroaromatic chalcones. AB - The critical role of nuclear topoisomerase enzymes during cell proliferation process guided topoisomerases to be one of the major targets for anticancer drug development. We have designed and synthesized 22 heteroaromatic ring incorporated chalcone derivatives substituted with epoxide or thioepoxide. Topoisomerase enzyme inhibitory activity and cytotoxic tests were also conducted to evaluate compounds' pharmacological efficacy. In the topoisomerase I inhibitory test, compound 1 was most active one, 24% of inhibition at 20MUM, among all the compounds but it was lower than camptothecin. Compounds 9, 11, and 13 inhibited the function of topoisomerase II more strongly than etoposide with almost same magnitude (around 90% and 30% inhibition at 100 and 20MUM, respectively) which were higher than those of etoposide (72% and 18% inhibition). In the cytotoxicity test, compound 9 inhibited T47D cancer cell growth with the IC50 value of 6.61+/ 0.21MUM. On the other hand, compound 13 (IC50: 4.32+/-0.18MUM) effectively suppressed MDA-MB468 cancer cell growth. PMID- 27707626 TI - Inhibition of the metastatic progression of breast and colorectal cancer in vitro and in vivo in murine model by the oxidovanadium(IV) complex with luteolin. AB - The anticancer and antimetastatic behavior of the flavonoid luteolin and its oxidovanadium(IV) complex [VO(lut)(H2O)2]Na.3H2O (VOlut) has been investigated. Considering that the complex displayed strong anticancer activity on MDAMB231 human breast cancer cell line we herein determined through in vitro assays that the complex would probably reduce breast cancer cell metastasis in a higher extent than the natural antioxidant. In the CT26 colon cancer cell line a stronger anticancer effect has also been determined for the complex (IC50 0.9MUM) and in addition it did not exert toxic effects on normal colon epithelial cells at concentrations up to 10MUM. Working with a murine model of highly aggressive, orthotopic colon cancer model (CT26 cancer cell lines) it has been determined that the complex might prevent metastatic dissemination of the colon cancer cells to the liver. The flavonoid luteolin also exerted anticancer effects (at a low degree, IC50 5.9MUM) on CT26 cell line and produced a 24% reduction of colon cancer liver metastasis. PMID- 27707627 TI - Sobetirome prodrug esters with enhanced blood-brain barrier permeability. AB - There is currently great interest in developing drugs that stimulate myelin repair for use in demyelinating diseases such as multiple sclerosis. Thyroid hormone plays a key role in stimulating myelination during development and also controls the expression of important genes involved in myelin repair in adults. Because endogenous thyroid hormone in excess lacks a generally useful therapeutic index, it is not used clinically for indications other than hormone replacement; however, selective thyromimetics such as sobetirome offer a therapeutic alternative. Sobetirome is the only clinical-stage thyromimetic that is known to cross the blood-brain-barrier (BBB) and we endeavored to increase the BBB permeability of sobetirome using a prodrug strategy. Ester prodrugs of sobetirome were prepared based on literature reports of improved BBB permeability with other carboxylic acid containing drugs and BBB permeability was assessed in vivo. One sobetirome prodrug, ethanolamine ester 11, was found to distribute more sobetirome to the brain compared to an equimolar peripheral dose of unmodified sobetirome. In addition to enhanced brain levels, prodrug 11 displayed lower sobetirome blood levels and a brain/serum ratio that was larger than that of unmodified sobetirome. Thus, these data indicate that an ester prodrug strategy applied to sobetirome can deliver increased concentrations of the active drug to the central nervous system (CNS), which may prove useful in the treatment of CNS disorders. PMID- 27707629 TI - Richter's Transformation in the Era of Kinase Inhibitor Therapy: A Review. AB - Richter's transformation (RT) is the transformation of chronic lymphocytic leukemia (CLL) into rapidly progressive B-cell lymphoma. This disease has long been recognized as a difficult-to-treat illness with poor survival outcomes. Although the incidence of RT has been well documented in previous studies, less is understood in the era of novel therapeutics, such as kinase inhibitors (KIs). The present review discusses the current risk factors, incidence, and outcomes of patients with RT in the modern era of KI therapy. Although the outcomes remain poor for RT patients after KI therapy, the most up-to-date studies have shown no increased incidence of RT in this patient population. Additionally, the present review reports the outcomes from the most recent data on novel therapies under investigation for patients with RT. PMID- 27707628 TI - Design, synthesis and evaluation of small molecule CD4-mimics as entry inhibitors possessing broad spectrum anti-HIV-1 activity. AB - Since our first discovery of a CD4-mimic, NBD-556, which targets the Phe43 cavity of HIV-1 gp120, we and other groups made considerable progress in designing new CD4-mimics with viral entry-antagonist property. In our continued effort to make further progress we have synthesized twenty five new analogs based on our earlier reported viral entry antagonist, NBD-11021. These compounds were tested first in HIV-1 Env-pseudovirus based single-cycle infection assay as well as in a multi cycle infection assay. Four of these new compounds showed much improved antiviral potency as well as cytotoxicity. We selected two of the best compounds 45A (NBD 14009) and 46A (NBD-14010) to test against a panel of 51 Env-pseudotyped HIV-1 representing diverse subtypes of clinical isolates. These compounds showed noticeable breadth of antiviral potency with IC50 of as low as 150nM. These compounds also inhibited cell-to-cell fusion and cell-to-cell HIV-1 transmission. The study is expected to pave the way of designing more potent and selective HIV 1 entry inhibitors targeted to the Phe43 cavity of HIV-1 gp120. PMID- 27707630 TI - Phospholipase Cgamma in Toll-like receptor-mediated inflammation and innate immunity. AB - Among the phospholipase C (PLC) isoforms, PLCgamma not only has unique structural characteristics in terms of harboring SH2 and SH3 domains but also mediates growth factor-induced signaling pathways. PLCgamma isoforms are expressed in several innate immune cell types, including macrophages, natural killer cells, mast cells, and neutrophils. Stimulation of Fc receptor or integrin in innate immune cells induces PLCgamma activation, which leads to phosphoinositide hydrolysis and calcium increase. The products of PLCgamma activity mediate the innate immune response by regulating respiratory burst, phagocytosis, cell adhesion, and cell migration. PLCgamma also regulates the inflammatory response by affecting Toll-like receptor-mediated signaling. Here, we briefly review the current understanding of the functional role of PLCgamma in inflammation and innate immunity in some innate immune cell types. PMID- 27707631 TI - Stabilization exercise compared to general exercises or manual therapy for the management of low back pain: A systematic review and meta-analysis. AB - AIM: We performed a systematic review with a meta-analysis to examine the efficacy of stabilization exercises versus general exercises or manual therapy in patients with low back pain. DESIGN: We searched MEDLINE, Cochrane Controlled Trials, Scielo, and CINAHL (from the earliest date available to November 2014) for randomized controlled trials that examined the efficacy of stabilization exercises compared to general exercises or manual therapy on pain, disability, and function in patients with low back pain. Weighted mean differences (WMD) and 95% confidence intervals were calculated. RESULTS: Eleven studies met the inclusion criteria (413 stabilization exercises patients, 297 general exercises patients, and 185 manual therapy patients). Stabilization exercises may provide greater benefit than general exercise for pain reduction and improvement in disability. Stabilization exercise improved pain with a WMD of -1.03 (95% CI: 1.29 to -0.27) and improved disability with a WMD of -5.41 (95% CI: -8.34 to 2.49). There were no significant differences in pain and disability scores among participants in the stabilization exercise group compared to those in the manual therapy group. CONCLUSIONS: Stabilization exercises were as efficacious as manual therapy in decreasing pain and disability and should be encouraged as part of musculoskeletal rehabilitation for low back pain.

AB - As evidence linking Zika virus with serious health complications strengthens, public health officials and clinicians worldwide need to know which locations are likely to be at risk for autochthonous Zika infections. We created risk maps for epidemic and endemic Aedes-borne Zika virus infections globally using a predictive analysis method that draws on temperature, precipitation, elevation, land cover, and population density variables to identify locations suitable for mosquito activity seasonally or year-round. Aedes mosquitoes capable of transmitting Zika and other viruses are likely to live year-round across many tropical areas in the Americas, Africa, and Asia. Our map provides an enhanced global projection of where vector control initiatives may be most valuable for reducing the risk of Zika virus and other Aedes-borne infections.

PMID- 27707633 TI - Long-term Results of Inframalleolar Bypass for Critical Limb Ischaemia. AB - INTRODUCTION: As the population ages and the incidence of diabetes increases, the expected number of patients with critical limb ischaemia (CLI) requiring distal revascularization will remain high or even increase. The aim of this study was to investigate the long-term results of inframalleolar bypass. MATERIAL AND METHODS: A total of 352 inframalleolar bypasses for CLI performed between 2002 and 2013 were included. Risk factors were evaluated and patency (both clinical and imaging based), leg salvage, survival, and amputation free survival (AFS) assessed. RESULTS: The median follow up was 30 months (mean 42 months, range 1-186 months). The median age of the study population was 73 years, and 67% of the patients were male. The incidence of diabetes was 69%. In the majority of cases (82%), the indication for bypass was an ulcer or gangrene, and the remaining 18% of the patients had rest pain. Primary, assisted primary, and secondary clinical patency was 71.2%, 76.5%, 81.0%, and 59.7%, 69.3%, and 70.7%, and 49.0%, 58.6%, and 68.4% at 1, 5, and 10 years, respectively. The last imaging based secondary patency at 1, 5, and 10 years was 79.3%, 68.1%, and 62.8%, respectively. The popliteal artery as the inflow artery (n = 194) was associated with superior primary (p = .013), assisted primary (p = .028), and secondary patency (p = .014) when compared with bypasses originating from the femoral artery (n = 158). The leg salvage rate at 1, 5, and 10 years was 78.6%, 72.0%, and 67.2%, respectively. Leg salvage was equal in patients with and without diabetes (p = .460). The respective survival and AFS rates at 1, 5, and 10 years were 70.3%, 37.4%, and 15.9%, and 58.4%, 29.8%, and 12.8%. CONCLUSION: Bypass to the foot arteries yielded excellent long-term patency, and good limb salvage can be achieved in both non-diabetic and diabetic patients.

PMID- 27707636 TI - Ablative fractional CO2 laser for burn scar reconstruction: An extensive subjective and objective short-term outcome analysis of a prospective treatment cohort. AB - BACKGROUND: The introduction of ablative fractional CO2 lasers (CO2-AFL) for burn scar management shows promising results. Whilst recent studies have focused on objective scar outcomes following CO2-AFL treatment, to date no data on patient subjective factors such as quality of life are available. METHODS: A prospective study was initiated to analyze the safety and efficacy of the CO2-AFL. Various objective and subjective outcome parameters were prospectively collected from the date of first consultation and follow-up following treatment. Objective factors include the Vancouver Scar Scale (VSS), the Patient and Observer Scar Assessment Scale (POSAS), and ultrasound measurements of the thickness of the scar. Subjective parameters included the assessment of neuropathic pain and pruritus, as well as the evaluation of improvement of quality of life following CO2-AFL with the Burns Specific Health Scale (BSHS-B). For treatment effect analysis, patients were stratified according to scar maturation status (> or <2 years after injury). RESULTS: 47 patients with 118 burn scars completed at least one treatment cycle. At a median of 55 days (IQR 32-74) after CO2-AFL treatment all analyzed objective parameters decreased significantly: intra-patient normalized scar thickness decreased from a median of 2.4mm to 1.9mm (p<0.001) with a concomitant VSS-drop from a median of 7 to 6 (p<0.001). The overall POSAS patient scale decreased from a median of 9 to 5 (p<0.001) with similar effects documented in POSAS observer scales. Both pain and pruritus showed significant reduction. Quality of life increased significantly by 15 points (median 120 to 135; p<0.001). All of the identified changes following CO2-AFL were equally significant irrespective of scar maturation status. CONCLUSION: Our preliminary results confirm significant improvement in thickness, texture, colour, and symptoms following treatment with CO2-AFL. Foremost, quality of life of patients with both immature and mature scars (up to 23 years after injury) improved significantly after just one treatment session. To our knowledge, this is the first study to document such holistic treatment effects in burn patients treated by CO2-AFL. PMID- 27707637 TI - Healing time and incidence of hypertrophic scarring in paediatric scalds. AB - INTRODUCTION: Scald burns, which heal in less than 14 days, are seen to be at low risk of hypertrophic scar (HTS) formation. Consequently surgery is usually reserved for scalds likely to take more than 14 days to heal. With the use of silver based dressings over the past few years, anecdotally, we have observed a tendency to improved healing of scalds with conservative management and reduced need for surgical intervention. We aimed to investigate the effect of overall healing time of paediatric scalds on HTS formation over a five-year period (2011 15). METHODS: We retrospectively identified all new patients attending the Royal Children's Hospital (RCH) burns clinic from 31st January 2011-31st July 2015. Medical histories were reviewed for burns caused by scalds. Scar quality was determined from written records or clinical photographs. Patients were compared in groups based on healing time of <10 days, 10-14 days, 15-21 days, 22-30 days or >30 days. RESULTS: We studied 322 children, of which 52 (16.1%) developed HTS. There was a significantly higher incidence of HTS with increased time to healing (mean 34.5 days compared to 12.1 days, p<0.01). There were 25 patients that underwent surgical treatment with excision or debridement and split thickness skin graft of which 21 (84%) developed HTS. Grafting offered no benefit in HTS rate in the 22-30 days to heal group. CONCLUSIONS: Our study confirms that there is a link between prolonged healing time of scald wounds and HTS. The danger of slow healing for scarring despite grafting, suggests this operation should be performed earlier than current practice to allow complete healing in less than 3 weeks.

PMID- 27707640 TI - Comparison of three cooling methods for burn patients: A randomized clinical trial. AB - Tap water may not be readily available in numerous places as a first aid for burns and, therefore, tea tree oil products are recommended alternatives. Our aim in this study was to compare the cooling effects of three burn-cooling methodologies, running tap water, Burnshield(r), and Burn Cool Spray(r), and suggest indications for each cooling method. This randomized, controlled, study enrolled patients with burns who used the emergency service of Seoul Bestian Hospital from June 2015 to October 2015. The allocation of the cooling methods was randomly generated using a computer. We cooled the burn wounds by applying one of the three methods and measured the skin surface temperature and pain level using a visual analog scale (VAS) scoring. Ninety-six patients were enrolled in this study. The variability in the median(IQR) skin temperatures of the three groups was from 33.5 degrees C (31.5-35.0) to 28.7 degrees C (25.9-30.9), 33.8 degrees C (32.0-35.4) to 33.2 degrees C (30.5-35.0), and 34.0 degrees C (32.0 35.1) to 34.4 degrees C (32.7-35.6) for the tap water, Burn Cool Spray(r), and Burnshield(r), respectively. The variability of the mean VAS pain scores was 6.9 to 4.8 (tap water), 5.6 to 4.5 (Burn Cool Spray(r)), and 5.5 to 3.3 (Burnshield(r)). The reduction of skin surface temperature by tap water was significantly greater than that by the other two methods. All three methods reduced the VAS pain score after 20min of treatment (p<0.001). The tap water had a similar effect to that of the Burn Cool Spray(r) but significantly better than that of Burnshield(r). There was a significant difference in the skin surface temperature and VAS pain score reduction (p=0.014 and p=0.007, respectively) between the groups cooled by tap water below and above 24 degrees C. The patients who visited the center within 30min showed a significantly higher skin temperature than those who came after 30min did (p=0.033). Tap water and Burn Cool Spray(r) reduced the skin surface temperature, but the Burnshield(r) slightly increased it. All three cooling methods were effective in relieving pain. The temperature of the tap water used was related to the reduction in skin surface temperature and VAS pain score. The patients who visited the hospital within 30min of their burn accident needed a longer cooling time to attain a comparable skin surface temperature to those who visited after 30min. PMID- 27707641 TI - Early assessment and identification of posttraumatic stress disorder, satisfaction with appearance and coping in patients with burns. AB - BACKGROUND: The first year after severe burn is a psychologically challenging period for the patient. Patients may still struggle with burn-related physical and psychological problems such as posttraumatic stress disorder (PTSD) and body image dissatisfaction (BID). AIM: This study investigates the presence of PTSD, BID and coping, at three, six and twelve months after discharge for early identification of patients in need of focused support during rehabilitation. METHODS: Fifty-two adult patients with different degrees of burns were followed at three, six and twelve months after discharge and 36 patients completed all assessment points. A standardized clinical protocol was used for systematic assessment of PTSD (IES-R), BID (SWAP-Swe) and Coping (CBQ). The follow-up included an intervention with a burn nurse as a complement to the existing program. RESULTS: Approximately half of the patients had a risk of developing PTSD three months after discharge from hospital, and body image dissatisfaction was found to potentially predict risk of PTSD during follow-up. CONCLUSIONS: The findings suggest that it is important to include patients with less extensive burns in follow-up as this group is at risk of development of PTSD. Using standardized questionnaires in early follow-up along with assessment of body image dissatisfaction may facilitate detection of psychological problems. PMID- 27707642 TI - The effect of smoking status on burn inhalation injury mortality. AB - INTRODUCTION: Three factors that effect burn mortality are age, total body surface of burn (TBSA), and inhalation injury. Of the three, inhalation injury is the strongest predictor of mortality thus its inclusion in the revised Baux score (age+TBSA+17* (inhalation injury, 1=yes, 0=no)). However, the weighted contribution of specific comorbidities such as smoker status on mortality has traditionally not been accounted for nor studied in this subset of burn patients. We therefore sought to examine the impact of current tobacco and/or marijuana smoking in patients with inhalation injury. METHODS: A retrospective analysis of patients admitted to a regional burn center from 2002 to 2012. Independent variables analyzed included basic demographics, burn mechanism, presence of inhalation injury, TBSA, pre-existing comorbidities, and smoker status. Bivariate analysis was performed and logistic regression modeling using significant variables was utilized to estimate odds of mortality. RESULTS: There were a total of 7640 patients over the study period. 7% (n=580) of the burn cohort with inhalation injury were included in this study. In-hospital burn mortality for inhalation injury patients was 23%. Current smokers (20%) included cigarette smokers and marijuana users, 19% and 3%, respectively. Preexisting respiratory disease (17%) was present in 36% of smokers compared to 13% of non-smokers (p<0.001). Smokers had significantly lower mortality rate (9%) compared to non smokers (26%, p<0.01). The logistic regression model for mortality outcomes identified statistically four significant variables: age, TBSA, ethnicity, and smoker status (OR=0.41, 95% CI=0.18-0.93). Presence of comorbidities, including preexisting respiratory disease, was not significant. CONCLUSION: In the sub group of burn patients with inhalation injury, the odds of mortality significantly decreased in pre-existing smokers after adjusting for significant covariates. We postulate that an immune tolerance mechanism that modulates and diminishes the pro-inflammatory response confers a survival advantage in smokers after exposure to acute smoke inhalation injury. Future prospective studies in human and/or animal models are needed to confirm these findings. PMID- 27707643 TI - Outpatient workload in the NHS: A new challenge for the burn services? AB - The aim of this study was to evaluate the impact of outpatient care on activities at the Adults' Regional Burns Centre and the Children's Regional Burns Unit, Mid Yorkshire Hospitals NHS Trust UK, where outpatient and inpatient responsibilities are shared between the nursing staff. Data for all inpatient and outpatient interactions (all care related activities with the presence of a Registered Nurse (RN)) was collected prospectively by the attending RN for two consecutive months (October and November 2014). We also retrospectively collected data related to daily RN staffing levels, and Centre/Unit admissions and discharges. We compared our results with the staffing standard recommended by the National Burn Care Review 2001 and the National Burn Care Standards 2013. In the two months analysed we recorded a total number of 1232 interactions: 240 for the adult inpatient service, 385 for the adult outpatient service, 155 for the paediatric inpatient service, 452 for the paediatric outpatient service. Considering this burden and collating it with daily RN staffing levels, we highlighted an understaffing in 42.6% (26/61) of the days for the Adult Regional Burn Centre and in 100% (61/61) of the days and nights for the Children Regional Burn Unit. The impact of outpatients on the activities of a Burns Centre/Unit is a factor that should be taken into account when evaluating staffing needs and planning services. This is a variable not currently considered in any guideline for safe staffing. PMID- 27707644 TI - Effect of acoustic parameters on the cavitation behavior of SonoVue microbubbles induced by pulsed ultrasound. AB - SonoVue microbubbles could serve as artificial nuclei for ultrasound-triggered stable and inertial cavitation, resulting in beneficial biological effects for future therapeutic applications. To optimize and control the use of the cavitation of SonoVue bubbles in therapy while ensuring safety, it is important to comprehensively understand the relationship between the acoustic parameters and the cavitation behavior of the SonoVue bubbles. An agarose-gel tissue phantom was fabricated to hold the SonoVue bubble suspension. 1-MHz transmitting transducer calibrated by a hydrophone was used to trigger the cavitation of SonoVue bubbles under different ultrasonic parameters (i.e., peak rarefactional pressure (PRP), pulse repetition frequency (PRF), and pulse duration (PD)). Another 7.5-MHz focused transducer was employed to passively receive acoustic signals from the exposed bubbles. The ultraharmonics and broadband intensities in the acoustic emission spectra were measured to quantify the extent of stable and inertial cavitation of SonoVue bubbles, respectively. We found that the onset of both stable and inertial cavitation exhibited a strong dependence on the PRP and PD and a relatively weak dependence on the PRF. Approximate 0.25MPa PRP with more than 20MUs PD was considered to be necessary for ultraharmonics emission of SonoVue bubbles, and obvious broadband signals started to appear when the PRP exceeded 0.40MPa. Moreover, the doses of stable and inertial cavitation varied with the PRP. The stable cavitation dose initially increased with increasing PRP, and then decreased rapidly after 0.5MPa. By contrast, the inertial cavitation dose continuously increased with increasing PRP. Finally, the doses of both stable and inertial cavitation were positively correlated with PRF and PD. These results could provide instructive information for optimizing future therapeutic applications of SonoVue bubbles.

AB - The objectives of the present work are to extract pectin from industrial waste of Musa balbisiana by ultrasound assisted citric acid mediated extraction method and optimization was done through central composite statistical experimental design under response surface methodology. The outcomes of this study exhibited that, process variables (ultrasound power, pH and extraction time) had considerable influence on the pectin extraction. Second order mathematical equation was constructed to predict the data through regression analysis. The optimal extraction process condition was ultrasound power of 323w, pH of 3.2, extraction time of 27min and SL (solid-liquid) ratio of 1:15g/ml. The mean experimental yield of pectin (8.99+/-0.018%) was fine accord among predicted yield of pectin (9.02%). PMID- 27707646 TI - Ultrasound-assisted Fenton process using siderite nanoparticles prepared via planetary ball milling for removal of reactive yellow 81 in aqueous phase. AB - Nano-sized siderite was used as catalyst for the heterogeneous Fenton process combined with ultrasonic irradiation to degrade reactive yellow 81 (RY-81) in the aqueous phase. As the most efficient process, nano-sized siderite prepared via ball milling was chosen to carry out the experiments. 6h milled siderite at initial pH of 3.0 led to the highest removal efficiency of 92.09% within the reaction time of 30min. At a short reaction time of 20min, increasing siderite nanoparticles dosage from 0.3 to 0.75g/L resulted in increasing removal efficiency from 49.82 to 79.86%, respectively, while further increase in the dosage caused a substantial decrease in the efficiency. In the case of the effect of solute concentration, increasing the dye up to 400mg/L led to a significant decrease in the removal efficiency (65.77%). The presence of 0.01M Na2CO3 and C2H5OH significantly diminished the decolorization efficiency of RY-81 (<10%) with initial concentration of 100mg/L. The intermediates produced during the treatment process were also identified using GC-MS analysis. This research suggested that ball milled siderite is a potential catalyst for the efficient decolorization of textile effluents via ultrasound-assisted Fenton process. PMID- 27707647 TI - Sonochemical preparation of stable porous MnO2 and its application as an efficient electrocatalyst for oxygen reduction reaction. AB - Porous MnO2 as a non-noble metal oxygen reduction reaction (ORR) electrocatalyst was prepared by a simple sonochemical route. The as-prepared porous MnO2 exhibited higher electrocatalytic activity, superior stability and better methanol tolerance than commercial Pt/C catalyst in alkaline media. Furthermore, the ORR proceeded via a nearly four-electron pathway. Cyclic voltammetry (CV) and rotating-disk electrode (RDE) measurements verified that the ORR enhancement was attributed to the porous structure and good dispersity, which facilitated sufficient transport of ions, electrons, O2 and other reactants in the process of ORR. The results indicated that a facile and feasible sonochemical route could be used to prepare highly active porous MnO2 electrocatalyst for ORR, which might be promising for direct methanol fuel cells. PMID- 27707648 TI - Comparison of patency rates and clinical impact of different reconstruction methods following portal/superior mesenteric vein resection during pancreatectomy. AB - INTRODUCTION: Few studies have compared patency rates of the different methods of venous reconstruction (VR) during a pancreatectomy. This study aimed to evaluate the patency rates and the clinical impact of various reconstruction methods. METHODS: For the meta-analysis, databases were systematically searched to identify studies reporting the outcomes of patients who underwent PVR/SMVR. For the retrospective study, clinical data were retrospectively analyzed from patients who underwent a pancreatectomy and VR between Feb. 2009 and Oct. 2015. Patency was assessed by CT and/or ultrasound. RESULTS: For the meta-analysis, the long-term patency rates of the primary repair group and the autologous graft group were significantly higher than that of the synthetic graft group. For the retrospective study, the reconstruction consisted of primary repair in 62 cases (89.8%) and synthetic grafting in 7 cases (10.1%). Synthetic grafting was more likely to cause acute thrombosis compared with primary repair for PVR/SMVR (85.7% versus 16.7%). Acute thrombosis was associated with decreased median survival (12 versus 6 months) and increased hazard of death. Late thrombosis and stenosis were not associated with survival or serious clinical impact. Median survival for the primary repair group and the synthetic grafting group was 12 and 7 months, respectively. CONCLUSION: Primary repair following PVR/SMVR is preferred and can be achieved in most situations. Stenosis should be noted when with risk factors (long segmental and tension), but it produced little clinical impact. Synthetic grafting was associated with a higher thrombosis rate. Acute thrombosis is associated with increased mortality and decreased survival. PMID- 27707649 TI - Rosmarinic acid inhibits inflammation and angiogenesis of hepatocellular carcinoma by suppression of NF-kappaB signaling in H22 tumor-bearing mice. AB - The aim of this study was to explore the anti-tumor effect and therapeutic potential of rosmarinic acid (RA) in the treatment of hepatocellular carcinoma (HCC). RA at 75, 150 and 300 mg/kg was given to H22 tumor-bearing mice by intragastric administration once daily for 10 consecutive days. Levels of inflammatory and angiogenic factors, including interleukin-1beta (IL-1beta), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), vascular endothelial growth factor (VEGF), and transforming growth factor-beta (TGF-beta) were measured by enzyme linked immunosorbent assays (ELISA). Protein levels of phosphorylated NF-kappaB p65 and p65 were detected by western blot. mRNA level of NF-kappaB p65 was analyzed by qRT-PCR. The results showed that RA could effectively suppress tumor growth with fewer toxic effects by regulating the secretion of cytokines associated with inflammation and angiogenesis, and suppressing the expression of NF-kappaB p65 in the xenograft microenvironment. Our findings unveil the possible anti-tumor mechanisms of RA and support RA as a potential drug for the treatment of HCC. PMID- 27707650 TI - Dendritic cells tip the balance towards induction of regulatory T cells upon priming in experimental autoimmune encephalomyelitis. AB - Counter-balancing regulatory mechanisms, such as the induction of regulatory T cells (Treg), limit the effects of autoimmune attack in neuroinflammation. However, the role of dendritic cells (DCs) as the most powerful antigen presenting cells, which are intriguing therapeutic targets in this context, is not fully understood. Here, we demonstrate that conditional ablation of DCs during the priming phase of myelin-specific T cells in experimental autoimmune encephalomyelitis (EAE) selectively aborts inducible Treg (iTreg) induction, whereas generation of T helper (Th)1/17 cells is unaltered. DCs facilitate iTreg induction by creating a milieu with high levels of interleukin (IL)-2 due to a strong proliferative response. In the absence of DCs, B220+ B cells take over priming of Th17 cells in the place of antigen-presenting cells (APCs), but not the induction of iTreg, thus leading to unregulated, severe autoimmunity.

PMID- 27707652 TI - Bladder continent catheterizable conduit (the Mitrofanoff procedure): Long-term issues that should not be underestimated. AB - BACKGROUND: Effective bladder emptying by clean intermittent catheterization for children with severe bladder dysfunction is critical for renal preservation and social integration. Use of a continent catheterizable conduit (CCC) as urethral alternative procedure provides effective bladder drainage. However, it brings a substantive maintenance. METHODS: Retrospective review of the indications and long-term outcomes of 54 patients with a Mitrofanoff procedure in a single center over a 20-year period (1995-2015). RESULTS: Indications of CCC include 21 neurogenic bladders, 12 patients with epispadias/exstrophy, 13 bladder outlet obstruction, 6 malignancies and 2 cloaca. Median age at surgery was 8.3years (4months-20years). The appendix was used in 76% of cases. Most frequently encountered complication was stomal stenosis (n=17/34, 50%), occurring at median time of 9months (2months-13years). The other complications were: leakage in 9 (26.5%); conduit stricture in 5 (14.7%), angulation of the conduit in 2 (5.8%) and prolapse in one (3%). Operative revision was encountered by 33 (61%) patients, the majority in the first 2years. Median follow-up was 4.3years (3months-16years). CONCLUSIONS: CCC has a high incidence of complication. It has to be used only when the native urethra is not suitable for catheterization. Carers, patients and families must be prepared to deal with both the complexity of index conditions and the complications of this procedure. PMID- 27707653 TI - The impact of morbid obesity on solid organ injury in children using the ATOMAC protocol at a pediatric level I trauma center. AB - INTRODUCTION: Obesity is an epidemic in the pediatric population. Childhood obesity in trauma has been associated with increased incidence of long-bone fractures, longer ICU stays, and decreased closed head injuries. We investigated for differences in the likelihood of failure of non-operative management (NOM), and injury grade using a subset of a multi-institutional, prospective database of pediatric patients with solid organ injury (SOI). METHODS: We prospectively collected data on all pediatric patients (<18years) admitted for liver or splenic injury from September 2013 to January 2016. SOI was managed based upon the ATOMAC protocol. Obesity status was derived using CDC definitions; patients were categorized as non-obese (BMI <95th percentile) or obese (BMI >=95th percentile). The ISS, injury grade, and NOM failure rate were calculated among other data points. RESULTS: Of 1012 patients enrolled, 117 were identified as having data regarding BMI. Eighty-four percent of patients were non-obese; 16% were obese. The groups did not differ by age, sex, mechanism of injury, or associated injuries. There was no significant difference in the rate of failure of non operative management (8.2% versus 5.3%). Obesity was associated with higher likelihood of severe (grade 4 or 5) hepatic injury (36.8% versus 15.3%, P=0.048) but not a significant difference in likelihood of severe (grade 4 or 5) splenic injury (15.3% versus 10.5%, P=0.736). Obese patients had a higher mean ISS (22.5 versus 16.1, P=0.021) and mean abdominal AIS (3.5 versus 2.9, P=0.024). CONCLUSION: Obesity is a risk factor for more severe abdominal injury, specifically liver injury, but without an associated increase in failure of NOM. This may be explained by the presence of hepatic steatosis making the liver more vulnerable to injury. A protocol based upon physiologic parameters was associated with a low rate of failure regardless of the pediatric obesity status. LEVEL OF EVIDENCE: Level II prognosis. PMID- 27707654 TI - Can IQ predict parent-reported behavioral and emotional problems in children with neurological deficiencies? AB - OBJECTIVE: The aim of the current study was to investigate whether total intelligence scores (FSIQ) and/or a discrepancy in intelligence can predict behavioral or emotional problems in children with neurological deficiencies. METHOD: The population consists of children with neurological deficiencies (N = 610, ranging from 6 to 17 years), referred due to concerns on the (educational) development of the child to a tertiary outpatient clinic. All children were tested with the Dutch Wechsler Intelligence Scale for Children - third edition (WISC-III-NL). A VIQ-PIQ discrepancy score was calculated by subtracting the performance capacities of the verbal capacities. The effects of demographic variables, FSIQ, and the VIQ-PIQ discrepancy on two parent-rated questionnaires measuring behavior and emotions in children were analyzed with linear and logistic regression models. RESULTS AND CONCLUSION: The VIQ-PIQ discrepancy was not predictive of behavioral or emotional problems recorded on the above mentioned parent-rated questionnaires. The FSIQ score, age, and sex were predictive to some extent: increases in age and FSIQ led to a decrease of reported problems, and boys showed more problems than girls. Children with neurological deficiencies had on average significantly higher verbal capacities than performance capacities, in line with the neuropsychological principle that language survives brain damage whereas performance capacities are more affected. PMID- 27707655 TI - The juvenile head trauma syndrome - Deterioration after mild TBI: Diagnosis and clinical presentation at the Emergency Department. AB - BACKGROUND: Annually 14.000 children with traumatic brain injury (TBI) are admitted to the Emergency Department (ED) in the Netherlands. Presentation varies and a specific entity comprises the juvenile head trauma syndrome (JHTS) with secondary deterioration after a mild trauma. As outcome of JHTS can be fatal, early recognition is essential. AIM: To outline the epidemiology and clinical features of JHTS, in comparison to paediatric mild TBI patients without JHTS. METHODS: Retrospective study of 570 patients with mild TBI admitted to the ED of a level-one trauma centre from 2008 to 2014. Diagnosis of JHTS by experienced neurologists was compared with diagnosis by physicians at the ED. RESULTS: Physicians at the ED diagnosed JHTS more frequently (14%) compared to experienced neurologists (8%). JHTS occurred after a lucid interval varying from 5 to 225 min (mean 44 (SD 64)) with changes in consciousness. JHTS patients were younger compared to mild TBI patients (4.1 (SD 2.4) vs. 7.3 (SD 5.7), p < 0.01), (range: 1-10 years). Falls occurred more often in JHTS (84% vs. 69%, p = 0.03) and at presentation, vomiting (42% vs. 22%, p < 0.01) and changed behaviour (29% vs. 1%, p = 0.03) were more present compared to the mild TBI group. CONCLUSION AND DISCUSSION: JHTS occurs more often in children up to 10 years with falls as major cause of injury. Clues for recognition of this syndrome comprise changes in consciousness and vomiting or changed behaviour on presentation at the ED. For clinical practice, these factors should guide the decision for hospital admission or discharge. PMID- 27707656 TI - The International Classification of Functioning (ICF) to evaluate deep brain stimulation neuromodulation in childhood dystonia-hyperkinesia informs future clinical & research priorities in a multidisciplinary model of care. AB - The multidisciplinary team (MDT) approach illustrates how motor classification systems, assessments and outcome measures currently available have been applied to a national cohort of children and young people with dystonia and other hyperkinetic movement disorders (HMD) particularly with a focus on dyskinetic cerebral palsy (CP). The paper is divided in 3 sections. Firstly, we describe the service model adopted by the Complex Motor Disorders Service (CMDS) at Evelina London Children's Hospital and King's College Hospital (ELCH-KCH) for deep brain stimulation. We describe lessons learnt from available dystonia studies and discuss/propose ways to measure DBS and other dystonia-related intervention outcomes. We aim to report on current available functional outcome measures as well as some impairment-based assessments that can encourage and generate discussion among movement disorders specialists of different backgrounds regarding choice of the most important areas to be measured after DBS and other interventions for dystonia management. Finally, some recommendations for multi centre collaboration in regards to functional clinical outcomes and research methodologies for dystonia-related interventions are proposed. PMID- 27707657 TI - The relationship of dystonia and choreoathetosis with activity, participation and quality of life in children and youth with dyskinetic cerebral palsy. AB - AIM: To relate dystonia and choreoathetosis with activity, participation and quality of life (QOL) in children and youth with dyskinetic Cerebral Palsy (CP). METHODS: Fifty-four participants with dyskinetic CP (mean age 14y6m, SD 4y2m, range 6-22y) were included. The Dyskinesia Impairment Scale (DIS) was used to evaluate dystonia and choreoathetosis. Activity, participation and quality of life (QOL) were assessed with the Gross Motor Function Measure (GMFM), the Functional Mobility Scale (FMS), the Jebsen-Taylor Hand Function Test (JTT), the ABILHAND-Kids Questionnaire (ABIL-K), the Life Habits Kids (LIFE-H) and the Quality of Life Questionnaire for children with CP (CP-QOL). Spearman's rank correlation coefficient (rs) was used to assess the relationship between the movement disorders and activity, participation and QOL measures. RESULTS: Significant negative correlations were found between dystonia and the activity scales with Spearman's rank correlation coefficient (rs) varying between -0.65 (95% CI = -0.78 to -0.46) and -0.71 (95% CI = -0,82 to -0.55). Correlations were also found with the LIFE-H (rs = -0.43; 95%CI = -0.64 to -0.17) and the CP-QOL (rs = -0.32; 95%CI = -0.56 to -0.03). As far as choreoathetosis is concerned, no or only weak relationships were found with the activity, participation and quality of life scales. INTERPRETATION: This cross-sectional study is the first to examine the relationship of dystonia and choreoathetosis in dyskinetic CP with the level of activity, participation and QOL. The results revealed dystonia has a higher impact on activity, participation and quality of life than choreoathetosis. These findings seem to suggest it is necessary to first focus on dystonia reducing intervention strategies and secondly on choreoathetosis. PMID- 27707658 TI - Can digital reinvention of ecological monitoring remove barriers to its adoption by practitioners? A case study of deer management in Scotland. AB - Monitoring is one of the key tools employed to help understand the condition of the natural environment and inform the development of appropriate management actions. While international conventions encourage the use of standardised methods, the link between the information monitoring provides and local management needs is frequently overlooked. This problem is further exacerbated when monitoring is employed in areas where there are divergent interests among stakeholders in land use and management. Such problems are found in the management of wild deer across Scotland, where monitoring, in the form of habitat impact assessments, have been introduced as an innovation in sustainable deer management. However, the uptake of habitat impact assessments has been limited. We used deer management in Scotland as a case study to explore whether reinventing habitat impact assessments, and hosting the system on a familiar digital platform (a mobile phone) could help to remove perceived barriers to the implementation of assessments. Using the diffusion of innovations as a theoretical framework three sets of workshops were conducted with participants representing different stakeholder interests. While the proposed digital system did address perceived barriers to the conduct of habitat monitoring, in addition it revealed underlying concerns on the use and purpose of habitat monitoring as a tool in land management. Such concerns indicate friction between scientific and management perspectives, which need to be considered and addressed if monitoring is to become more widely acceptable as a tool to inform the management of natural resources. PMID- 27707659 TI - Precision Molecular Diagnosis Defines Specific Therapy in Combined Immunodeficiency with Megaloblastic Anemia Secondary to MTHFD1 Deficiency. AB - BACKGROUND: Methylenetetrahydrofolate dehydrogenase (MTHFD1) deficiency has recently been reported to cause a folate-responsive syndrome displaying a phenotype that includes megaloblastic anemia and severe combined immunodeficiency. OBJECTIVE: To describe our investigative approach to the molecular diagnosis and evaluation of immune dysfunction in a family with MTHFD1 deficiency. METHODS: The methods used were exome sequencing and analysis of variants in genes involved in the folate metabolic pathway in a family with 2 affected siblings. Routine laboratory and research data were analyzed to gain an in-depth understanding of innate, humoral, and cell-mediated immune function before and after folinic acid supplementation. RESULTS: Interrogation of exome data for concordant variants between the siblings in the genes involved in folate metabolic pathway identified a heterozygous mutation in exon 3 of the MTHFD1 gene that was shared with their mother. In view of highly suggestive phenotype, we extended our bioinformatics interrogation for structural variants in the MTHFD1 gene by manual evaluation of the exome data for sequence depth coverage of all the exons. A deletion involving exon 13 that was shared with their father was identified. Routine laboratory data showed lymphopenia involving all subsets and poor response to vaccines. In vitro analysis of dendritic cell and lymphocyte function was comparable to that in healthy volunteers. Treatment with folinic acid led to immune reconstitution, enabling discontinuation of all prophylactic therapies. CONCLUSIONS: Exome sequencing demonstrated MTHFD1 deficiency as a novel cause of a combined immunodeficiency. Folinic acid was established as precision therapy to reverse the clinical and laboratory phenotype of this primary immunodeficiency. PMID- 27707660 TI - Determinants of Incomplete Asthma Control in Patients with Allergic Rhinitis and Asthma. AB - BACKGROUND: Characterizing associations between the upper and lower airways is important for asthma management. OBJECTIVES: This study aimed to assess the determinants of incomplete asthma control in patients with allergic rhinitis (AR) and asthma. METHODS: Multiple factors including age, sex, atopy, smoking history, medication use, Asthma Control Questionnaire (ACQ) score, FEV1, fraction of exhaled nitric oxide (Feno), and rhinitis questionnaire score were examined. AR was defined by rhinitis symptoms and the sensitization to inhaled allergens. ACQ was used to dichotomize the subjects into the incompletely controlled group (ACQ score >=0.75) and the well-controlled group. The factors that contribute to incomplete asthma control were assessed by a multivariate analysis. RESULTS: A total of 260 patients with AR and asthma were enrolled and 108 patients (42%) were classified as incomplete asthma control. The incompletely controlled group was older (P < .05), and had more airflow limitation, more airway inflammation, and more severe rhinitis symptoms (all P < .001). In contrast, the well controlled group was more likely to be taking nasal corticosteroids (NCSs) (P < .01). In a multivariate model adjusted by age, asthma treatment, airflow limitation, and Feno, persistence and severity of rhinitis (odds ratio [OR], 2.57; 95% CI, 1.41-4.70, and OR, 2.00; 95% CI, 1.10-3.65) and nonuse of NCSs (OR, 3.83; 95% CI, 1.50-9.81) were independently associated with incomplete asthma control. CONCLUSIONS: The persistence and severity of AR and the use of NCSs were associated with the level of asthma control in patients with AR and asthma. Further studies are required to determine whether appropriate treatment of rhinitis would improve asthma control. PMID- 27707661 TI - Could Fractional Exhaled Nitric Oxide Test be Useful in Predicting Inhaled Corticosteroid Responsiveness in Chronic Cough? A Systematic Review. AB - BACKGROUND: Fractional exhaled nitric oxide (Feno) is a safe and convenient test for assessing TH2 airway inflammation, which is potentially useful in the management of patients with chronic cough. OBJECTIVE: To summarize the current evidence on the diagnostic usefulness of Feno for predicting inhaled corticosteroid (ICS) responsiveness in patients with chronic cough. METHODS: A systematic literature review was conducted to identify articles published in peer reviewed journals up to February 2015, without language restriction. We included studies that reported the usefulness of Feno (index test) for predicting ICS responsiveness (reference standard) in patients with chronic cough (target condition). The data were extracted to construct a 2 * 2 accuracy table. Study quality was assessed with Quality Assessment of Diagnostic Accuracy Studies 2. RESULTS: We identified 5 original studies (2 prospective and 3 retrospective studies). We identified considerable heterogeneities in study design and outcome definitions, and thus were unable to perform a meta-analysis. The proportion of ICS responders ranged from 44% to 59%. Sensitivity and specificity ranged from 53% to 90%, and from 63% to 97%, respectively. The reported area under the curve ranged from about 0.60 to 0.87; however, studies with a prospective design and a lower prevalence of asthma had lower area under the curve values. None measured placebo effects or objective cough frequency. CONCLUSIONS: We did not find strong evidence to support the use of Feno tests for predicting ICS responsiveness in chronic cough. Further studies need to have a randomized, placebo-controlled design, and should use validated measurement tools for cough. Standardization would facilitate the development of clinical evidence. PMID- 27707663 TI - An improved multi-objective optimization model for supporting reservoir operation of China's South-to-North Water Diversion Project. AB - An improved multi-objective optimization model based on goal programming (GP) for supporting reservoir operation was developed under inflow senarios of multiple runoff guarantee rates (i.e., 25%, 75%, perennial mean, and 95%) and ecological goals with the combination of steady- and pulse-state ecological water demands. Under these four scenarios, discharge flows of Danjingkou Reservoir would be 358.40, 369.67, 268.91 and 98.14*108m3/a, and those at Taocha Canal headwork would be 104.61, 86.62, 95.08 and 64.00*108m3/a, respectively. The generated results for stream flows could successfully meet the predetermined operational goals for the project. Comparatively, under the scenario of 95% runoff guarantee rate, the obtained strategies could not satisfy the ecological water demands. The modeling results indicated that the capacity of water diversion and storage for Danjiangkou Reservoir would be enhanced due to the operation of the South-to North Water Diversion Project. The results showed the risks associated with possible flooding would be comparatively low under those four runoff guarantee rates. This represents the current priority for flood control in Danjiangkou Reservoir needs to be changed into multiple ones including ecological water supply, water transfer, as well as downstream water security maintenance. PMID- 27707662 TI - Dietary predictors of urinary cadmium among pregnant women and children. AB - BACKGROUND: Cadmium is a toxic metal with modifiable exposure sources including diet. In pregnant women and children, unique dietary habits may contribute to DCd, and the relationship of diet to overall cadmium exposure can depend on specific factors during these transitional time periods. OBJECTIVES: This study aimed to identify and quantify food sources of DCd, describe the distribution of UCd, and determine the relationship of DCd and intake of specific foods with UCd, stratified by maternal smoking history, among pregnant women and children in a well-characterized Mexico City birth cohort. METHODS: Our sample included 192 pregnant women (third trimester) and 223 children (7-15years). DCd was calculated using FFQ and the U.S. TDS. We also measured UCd, maternal history of smoking, and additional covariates. RESULTS: Pregnant women and children had geometric mean UCd concentrations of 0.19+/-0.78MUg/L and 0.14+/-0.60MUg/L, respectively. On average, estimated daily DCd intake was 9.3+/-3.5MUg for women and 12.2+/ 5.4MUg for children. Adjusted linear regression models showed a positive association between DCd and UCd among women (p=0.03) and children (p=0.03) without a maternal history of smoking. Intake of fruit and vegetables among women and potato consumption among children were positively associated with UCd. CONCLUSIONS: Pregnant women and their children are exposed to cadmium at dietary and urinary levels similar to those previously reported. Higher estimated DCd for children than for women could be attributed to the different FFQs or related to dietary pattern changes between age groups. DCd contributed to UCd in those without a maternal smoking history. PMID- 27707665 TI - Are the Pyrenees a barrier for the transport of birch (Betula) pollen from Central Europe to the Iberian Peninsula? AB - This work provides a first assessment of the possible barrier effect of the Pyrenees on the atmospheric transport of airborne pollen from Europe to the North of the Iberian Peninsula. Aerobiological data recorded in three Spanish stations located at the eastern, central and western base of the Pyrenees in the period 2004-2014 have been used to identify the possible long range transport episodes of Betula pollen. The atmospheric transport routes and the origin regions have been established by means of trajectory analysis and a source receptor model. Betula pollen outbreaks were associated with the meteorological scenario characterized by the presence of a high-pressure system overm over Morocco and Southern Iberian Peninsula. France and Central Europe have been identified as the probable source areas of Betula pollen that arrives to Northern Spain. However, the specific source areas are mainly determined by the particular prevailing atmospheric circulation of each location. Finally, the Weather Research and Forecasting model highlighted the effect of the orography on the atmospheric transport patterns, showing paths through the western and easternmost lowlands for Vitoria-Gasteiz and Bellaterra respectively, and the direct impact of air flows over Vielha through the Garona valley. PMID- 27707664 TI - Seasonal effects to metallothionein responses to metal exposure in a naturalised population of Ruditapes philippinarum in a semi-enclosed estuarine environment. AB - The Manila clam (Ruditapes philippinarum), an invasive species in Northern Europe, can be used as a bioindicator of metal pollution. Seasonal effects on metallothionein (MT) production have not been considered in this species at the northernmost extent of its European distribution. This study assesses the annual seasonal effects on MT and metal concentrations in R. philippinarum from Poole Harbour, UK. R. philippinarum were collected in winter, spring, summer, and autumn throughout 2015, and MT and metal concentrations, as well as biotic and abiotic variables, were quantified. During winter, linear regression analysis showed significant positive relationships between tissue metal and MT concentrations. However, during spring and summer, these relationships were mostly insignificant. MT concentrations during spring had significant positive relationships with tissue and whole weight. Significant positive relationships were also observed between MT and condition index, during summer. During spring and summer, biotic factors seem to override the role of MT as a detoxification mechanism for metal exposure in this species. This is probably due to an increase in MT concentration in spring caused by gametogenesis, associated with increased tissue weight as the gonads expand. A depletion of energy resources, or physical stressors such as heat, may be attributed to the reduced MT production in clams of poor body condition in summer. The evidence from this study suggests that MT may only be a useful biomarker of metal pollution during winter in R. philippinarum in the UK. This verifies the natural variability of MT in this species at high latitudes, and highlights the potential and limits to a widely available bioindicator of metal pollution. PMID- 27707666 TI - Dissolved reactive phosphorus played a limited role in phosphorus transport via runoff, throughflow and leaching on contrasting cropping soils from southwest Australia. AB - PURPOSE: Phosphorus (P) lost from agricultural land by erosion, runoff, throughflow and leaching is of major concern for water resource managers worldwide. Previous study on soils from cropping land of southwest Western Australia suggested P loss as dissolved unreactive P (DURP) via leaching, but the implications for processes and rates of P transport in soils are not known. MATERIAL AND METHODS: Two contrasting soil profiles (sand and loam) from cropping land of southwest Western Australia were exposed to artificial rain in packed boxes and field runoff plots to examine P forms and fluxes in runoff, throughflow, leachate and soil solution after three P rates of application (equivalent to 0, 20 and 40kg P/ha). Solutions were analyzed for total P (TP), dissolved reactive P (DRP) and total dissolved P (TDP). Particulate P (PP) and DURP were calculated by subtracting DRP from TP and TDP respectively. RESULT AND DISCUSSION: In the sand profile, about 90% or more of P losses via runoff and leachate were in DURP and PP forms, whereas DRP was a minor contributor. Phosphorus load in soil solution, throughflow, leachate and run-off increased with increasing P rate. The relatively higher affinity of soil for DRP compared to DURP might cause the latter to be more mobile through profile in association with colloidal compounds <0.2MUm. Higher PP concentration for loam soil via throughflow is exacerbated by dispersed clay, which could be an additional process influencing P mobility in loam and duplex soils. CONCLUSION: The DRP played a limited role in P transport compared to PP and DURP that both appeared to be associated with soil particles or soil colloids in runoff, throughflow, leachate and soil solution. Further characterization of the latter forms of P is needed so that management practices can be developed to minimize P losses. PMID- 27707667 TI - Fractionation of radiocesium in soil, sediments, and aquatic organisms in Lake Onuma of Mt. Akagi, Gunma Prefecture using sequential extraction. AB - The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident has resulted in the contamination of the environment in Gunma Prefecture with radioisotope cesium (radio-Cs, 134Cs and 137Cs). Concentrations of radio-Cs >500Bqkg-1 were found in wakasagi (Hypomesus nipponensis) in Lake Onuma at the top of Mount (Mt.) Akagi in August 2011. To explain the mechanism of this contamination, monitoring studies have been conducted around Lake Onuma by measuring radio-Cs concentrations in samples of fish, aquatic plants, plankton, lake water, lake sediments, and surrounding soil. The leachability of radio-Cs was evaluated using sequential extraction by Tessier et al. The total concentration of radio-Cs in Lake Onuma ecosystems decreased gradually with time. In the brown forest soil, radio-Cs concentrations of 2000 to 6000Bqkg-1 were detected. The abundance ratio of the easy-elution form (exchangeable and carbonate forms) in the samples was <10%. The concentrations in phytoplankton samples were 3-6 times higher than those in wakasagi samples. The ratios of easy-elution forms increased by the rank in the food chain; 37% in phytoplankton, 78% in zooplankton, and 97% in wakasagi. It is likely that the lower ratio of the easy-elution form in phytoplankton is related to the adsorption of radio-Cs on suspended substances in the lake, as suggested by the analyses of aluminum and titanium in the phytoplankton, zooplankton, and wakasagi samples. The high concentrations of radio-Cs in wakasagi would be related also to the characteristics of closed mountain lakes. PMID- 27707668 TI - A case of tricuspid valve endocarditis due to Cardiobacterium hominis which emphasizes the shift between the poverty of clinical symptoms and the severity of cardiac damages. AB - Infectious endocarditis due to Cardiobacterium hominis is an uncommon event, accounting for less than 2% of all cases of infectious endocarditis. The infection of the tricuspid valve as it is reported here is extremely rare. We report the case of a tricuspid endocarditis due to Cardiobacterium hominis in a 56 year-old man who was admitted to hospital with pelvic and scapular pain. The diagnosis was established through positive blood cultures and echographic detection of a large tricuspid vegetation. Despite efficient antibiotic therapy, valve replacement was required. The clinical course of Cardiobacterium endocarditis is usually subacute, and the diagnosis may therefore be delayed. This case emphasizes the shift between the poverty of clinical symptoms and severity of cardiac damages, what we could call the Cardiobacterium paradox.

AB - Cytogenetic analyses (karyotype and, if necessary, appropriate complementary FISH analyses) are mandatory at diagnosis in acute lymphoblastic leukemia (ALL) as their results are taken into account in therapeutic protocols due to their diagnostic and prognostic values. In some cases, karyotype can be completed by other techniques (RT-PCR, RQ-PCR, DNA content, SNP-array, MLPA...) that can be equally or more informative than FISH. Here, we have tempted to establish guidelines concerning karyotype and FISH analyses according to the most recent data of the litterature which is reviewed here, completing the 2008 WHO classification with the recent new cytogenomic entities such as Ph-like ALL and indicating possible therapeutic implications. PMID- 27707672 TI - Cytogenetics in the management of lymphomas and lymphoproliferative disorders in adults and children: an update by the Groupe francophone de cytogenetique hematologique (GFCH). AB - Non-Hodgkin's lymphomas and lymphoproliferative disorders include a high number of heterogeneous entities, described in the 2008 WHO classification. This classification reflects the crucial role of a multidisciplinary approach which integrates cytogenetic results both for the notion of clonality and for differential diagnosis between these entities. The prognostic impact of some cytogenetic abnormalities or genome complexity is also confirmed for many of these entities. Novel provisional entities have been described, such as BCLU (B cell lymphoma unclassifiable with features intermediate between diffuse large B cell lymphoma and Burkitt lymphoma) for which karyotype is critical to distinguish BCLU from Burkitt's lymphoma. The karyotype can be established from any tumour or liquid infiltrated by lymphoma cells. Recent adaptations of technics for cellular cultures according to the subtype of known (or suspected) lymphoma have significantly improved the percentage of informative karyotypes. Conventional karyotypes remain the best technical approach recommended for most of these subtypes. Interphase and/or metaphase FISH also represents a solid and rapid approach, because of the significant number of recurrent (sometimes specific) rearrangements of these entities. Next generation sequencing technologies contribute to enrich genomic data and substantially improve the understanding of oncogenic mechanisms underlying these lymphoid malignancies. Some molecular biomarkers are already part of the diagnostic process (for example, somatic mutation of MYD88 in Waldenstrom disease) thus reinforcing the essential principle of a multidisciplinary approach for the diagnosis of all the mature lymphoid malignancies. PMID- 27707673 TI - Cytogenetics in the management of multiple myeloma: an update by the Groupe francophone de cytogenetique hematologique (GFCH). AB - Cytogenetics of multiple myeloma has evolved in recent years by the emergence of Interphasic fluorescence in situ hybridization (FISH) performed on sorted plasma cells detecting abnormalities independently of a proliferative and infiltrative index. Cytogenetic analysis plays a major part in the risk stratification of myeloma diagnosis due to prognostic impact of various cytogenetic abnormalities as well as to the association between emerging therapeutic approaches in MM. Thus, practice guidelines now recommend interphasic FISH or alternative molecular technics as the initial analysis for multiple myeloma. The Groupe francophone de cytogenetique hematologique (GFCH) proposes in this issue an update of managing multiple myeloma cytogenetics. PMID- 27707674 TI - Benefits of new immunoglobulin-derived biomarkers for the diagnosis and follow-up of patients with dysglobulinemia. AB - The diagnostics and follow-up of monoclonal gammopathies such as multiple myeloma require precise analysis of the monoclonal component as well as the other immunoglobulins isotypes, which might be limited by the sensitivity of standard laboratory methods. New serum biomarkers were developed for routine practice in the last decades, such as the free light chain assays and more recently the heavy/light chain assays. Studies have shown that serum free light chain measurement was useful in the identification and follow-up of pauci or nonsecretory myeloma, free light-chain multiple myeloma and AL amyloidosis. It is also an important prognostic marker for monoclonal gammopathy of undetermined significance and AL amyloidosis progression. Hevylite method enables quantitative analysis of heavy/light chain pairs of IgG, IgA and IgM immunoglobulins. This technique has a promising potential to enrich the standard analytic tools as it enables to assess the concentration and ratio of the levels of both tumor and physiological immunoglobulins (heavy/light chain pair suppression), which is not possible with serum protein electrophoresis or global quantitative analysis of immunoglobulin isotypes. This review includes the latest International myeloma working group recommendations and key data presented at the Euromedlab convention in June 2015 Paris regarding serum free light chain and heavy/light chain assays in the biological monitoring of dysglobulinemia. PMID- 27707675 TI - Serum proteomic signatures as biomarkers of primary biliary cirrhosis diagnosis and prognosis. AB - Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease considered as an autoimmune disease. To identify new biomarkers of PBC, serum profiling analysis using Surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) was employed. Twelve patients with either asymptomatic PBC (group 1, n=6) or PBC with a poor response to UDCA (group 2, n=6), were compared to healthy controls (group 3, n=6). Analysing the 18 sera by using four SELDI-TOF arrays under various conditions, we found four biomarkers of PBC at 5.9, 8.6, 8.9 and 9.0 kDa. The combination of the two arrays IMAC-40/Zn2+ and CM-10/pH 7 improved the positive diagnosis of this disease. We also found a biomarker of severity of PBC at 95.2 kDa on LSAX-30 array which characterized patients with a bad prognosis. In conclusion, our study identified several serum proteomics signatures as potential biomarkers of PBC for its diagnosis or prognosis. PMID- 27707676 TI - Erysipelothrix rhusiopathiae bacteremia: a challenging diagnosis! AB - Erysipelothrix rhusiopathiae, a Gram-positive bacillus, is reported to cause for cutaneous infections and endocarditis. We report a case of E. rhusiopathiae bacteremia without severe clinical illness. The patient, a 74-year-old man, is suffering from a chronic lymphoid leukemia (LLC). Following a trauma, the patient developed a bruise on the left inch. Because the site of shock seemed clinically infected, oral amoxicilline-acid clavulanic (AAC) treatment was started after withdrawn 1 set of blood cultures. These blood culture specimens yielded a Gram positive bacillus identified as E. rhusiopathiae by mass spectrometry MALDI-TOF (Microflex Bruker). The strain was sensitive to beta-lactam, fluoroquinolones and macrolides, resistant to vancomycin (natural resistance), and amikacin but sensitive to gentamicin. After 5 days of treatment by AAC, the patient became apyretic. One year after this episode, we reported no further symptoms of infection, or endocarditis. The natural resistance of E. rhusiopathiae in glycopeptides underlines the importance of a microbiological diagnosis. Indeed, vancomycine can be the treatment of first intention in Gram-positive bacillus bacteremia. The identification of bacteria using mass spectrometry is available the same day of the blood culture positivity and allows to prescribe the most adapted antibiotic treatment for the patient. PMID- 27707677 TI - Verification of a quantitative method: complete blood count by flow cytometry, the HematoFlowTM system (Beckman Coulter). AB - The HematoFlowTM system is used in the hematology laboratory of the University Hospital of Bordeaux since July, 2011. The HematoFlowTM solution is the combination of a sample preparator (FP1000) and a 5 color flow cytometer (FC500) linked by a middleware (RemisolTM). This system is used in second line when flags are activated by the hematology instrument and/or if the sample comes from the OncoHematology Department. Improvements in hematology disease diagnosis and follow-up were possible using this system. The laboratory has now entered in an accreditation procedure and needs to check this method in compliance with the COFRAC requirements.

PMID- 27707681 TI - [Heart disease in sports horses: Current recommendations of the 2014 ACVIM / ECEIM consensus statement]. AB - INTRODUCTION: Heart murmurs and arrhythmias are common in horses. Assessment of their clinical relevance concerning health, performance, safety and longevity of sports horses is of highest importance. A comprehensive cardiovascular examination is crucial for diagnosis and assessment of the severity of disease. Recently, an expert panel of the American College of Veterinary Internal Medicine (ACVIM) and the European College of Equine Internal Medicine (ECEIM) developed a consensus statement containing recommendations for sports horses with heart disease. This article summarizes the most relevant recommendations for practitioners, considering the most common and most important cardiac disorders in adult sports horses. These include mitral, aortic and tricuspid insufficiency, ventricular septal defects, atrial fibrillation as well as supraventricular and ventricular arrhythmias. Despite the fact that most horses with cardiovascular disease maintain a sufficient performance capacity, regular evaluations are indicated in horses with clinically relevant disorders. Under certain circumstances, horses with moderate to severe structural disease, with persistent untreated atrial fibrillation and with certain ventricular arrhythmias might still be used by informed adult riders. Horses with complex ventricular arrhythmias, pulmonary hypertension or congestive heart failure must not be ridden or driven and should be retired. PMID- 27707682 TI - Detection of 'Candidatus Neoehrlichia mikurensis' and other Anaplasmataceae and Rickettsiaceae in Canidae in Switzerland and Mediterranean countries. AB - INTRODUCTION: 'Candidatus Neoehrlichia mikurensis' is an emerging tick-borne zoonotic agent that primarily affects immunocompromised human patients. Dogs and foxes are frequently exposed to ticks, and both species are in close proximity to humans. This is the first study to systematically investigate the occurrence of 'Candidatus Neoehrlichia mikurensis' in Canidae in Europa. We analyzed 1'739 blood samples from dogs in Switzerland, Italy, Spain and Portugal and 162 blood samples from free-ranging red foxes (Vulpes vulpes) in Switzerland. All samples were tested using a previously described multiplex real-time PCR for the Anaplasmataceae family, the 'Candidatus Neoehrlichia' genus and the 'Candidatus Neoehrlichia mikurensis' species. All Anaplasmataceae positive samples were subsequently tested using specific real-time PCRs for Anaplasma phagocytophilum, Anaplasma platys, Ehrlichia canis and Rickettsia helvetica. Among the tested animals, one dog from Zurich tested positive for 'Candidatus Neoehrlichia mikurensis'. The 12-year old West Highland white terrier had been splenectomized 3 months prior to the blood collection and presented with polyuria/polydipsia. Fanconi syndrome was diagnosed based on glucosuria with normoglycemia and hyperaminoaciduria. A. platys and E. canis were detected in 14/249 dogs from Sicily and Portugal; two of the dogs were coinfected with both agents. Four Swiss foxes tested positive for A. phagocytophilium. R. helvetica was detected for the first time in a red fox. In conclusion, 'Candidatus Neoehrlichia mikurensis' infection should be considered in sick dogs, particularly when immunocompromised. The pathogen seems not to be widespread in Canidae in the investigated countries. Conversely, other Anaplasmataceae were more readily detected in dogs and foxes. PMID- 27707683 TI - Unexplained bleeding as primary clinical complaint in dogs infected with Angiostrongylus vasorum. AB - INTRODUCTION: Unexplained bleeding was the primary clinical complaint in 15 dogs diagnosed with A. vasorum and was observed in the mouth, as external bleeding, as large subcutaneous hematoma, as hemoptysis, in the brain, post ovariectomy, as epistaxis, in the anterior ocular chamber and on a tracheal intubation tube. In 8 dogs the cause of bleeding initially was suspected to be a minor trauma or a surgical complication, and various surgical approaches had been undertaken to eliminate the problem. In only 3 dogs respiratory signs were observed before the bleeding prompted referral. The median time elapsed between the first recognized clinical signs attributed to A. vasorum until diagnosis was 2 weeks (range1 day to 4 months). Four dogs died, 3 on the day of admission and 1 dog 4 days after admission. Suspected causes of death were respiratory failure and cerebral hemorrhage in 2 dogs each. Four dogs had been pre-treated with NSAIDs; of these, 2 dogs developed severe hemoptysis (1 died), 1 dog developed brain hemorrhage (and died), and 1 dog developed a large subcutaneous hematoma with marked anemia. Bleeding at various sites may be the only recognized abnormality in A. vasorum infection. Without a high index of suspicion, the diagnosis and appropriate therapy may be delayed to the point of a fatal outcome. Tests of coagulation were quite variable and the cause of bleeding likely multifactorial. PMID- 27707684 TI - [Uroliths of cats in Switzerland from 2002 to 2009]. AB - INTRODUCTION: In this study data on composition of uroliths collected from cats and epidemiologic data of affected cats in Switzerland from 2002 to 2009 are summarised. Of 884 stones analysed 50% (n=441) were composed of calcium oxalate, 45% (n=398) of struvite, 3% (n=18) of ammonium urate, 1% (n=12) were mixed stones, 1% (n=9) were composed of silica, 3 stones were solidified blood, 2 consisted of cystine and 1of xanthine. 40% of the ureteral stones were composed of struvite. Domestic cats had significantly less calcium oxalate stones compared to British Shorthair or Persian cats. Cats with calcium oxalate stones were older and cats with struvite stones were younger than other affected cats. Female and male cats were equally affected with stones. Compared to studies from other countries, in Switzerland silica stones occurred more often and ureteral stones were more often composed of Struvite. The present study shows that occurrence and prevalence of urinary calculi of cats from Switzerland exhibited only slight differences to studies from other countries.

AB - BACKGROUND: In Australia, there is growing use of technology supported knowledge translation (KT) strategies such as social media and mobile apps in health promotion and in Indigenous health. However, little is known about how individuals use technologies and the evidence base for the impact of these health interventions on health behavior change is meager. OBJECTIVE: The objective of our study was to examine how Facebook is used to promote health messages to Indigenous people and discuss how KT can support planning and implementing health messages to ensure chosen strategies are fit for the purpose and achieve impact. METHODS: A desktop audit of health promotion campaigns on smoking prevention and cessation for Australian Indigenous people using Facebook was conducted. RESULTS: Our audit identified 13 out of 21 eligible campaigns that used Facebook. Facebook pages with the highest number of likes (more than 5000) were linked to a website and to other social media applications and demonstrated stickiness characteristics by posting frequently (triggers and unexpected), recruiting sporting or public personalities to promote campaigns (social currency and public), recruiting Indigenous people from the local region (stories and emotion), and sharing stories and experiences based on real-life events (credible and practical value). CONCLUSIONS: KT planning may support campaigns to identify and select KT strategies that are best suited and well-aligned to the campaign's goals, messages, and target audiences. KT planning can also help mitigate unforeseen and expected risks, reduce unwarranted costs and expenses, achieve goals, and limit the peer pressure of using strategies that may not be fit for purpose. One of the main challenges in using KT systems and processes involves coming to an adequate conceptualization of the KT process itself. PMID- 27707687 TI - A Checklist for the Conduct, Reporting, and Appraisal of Microcosting Studies in Health Care: Protocol Development. AB - BACKGROUND: Microcosting is a cost estimation method that requires the collection of detailed data on resources utilized, and the unit costs of those resources in order to identify actual resource use and economic costs. Microcosting findings reflect the true costs to health care systems and to society, and are able to provide transparent and consistent estimates. Many economic evaluations in health and medicine use charges, prices, or payments as a proxy for cost. However, using charges, prices, or payments rather than the true costs of resources can result in inaccurate estimates. There is currently no existing checklist or guideline for the conduct, reporting, or appraisal of microcosting studies in health care interventions. OBJECTIVE: The aim of this study is to create a checklist and guideline for the conduct, reporting, and appraisal of microcosting studies in health care interventions. METHODS: Appropriate potential domains and items will be identified through (1) a systematic review of all published microcosting studies of health and medical interventions, strategies, and programs; (2) review of published checklists and guidelines for economic evaluations of health interventions, and selection of items relevant for microcosting studies; and (3) theoretical analysis of economic concepts relevant for microcosting. Item selection, formulation, and reduction will be conducted by the research team in order to develop an initial pool of items for evaluation by an expert panel comprising individuals with expertise in microcosting and economic evaluation of health interventions. A modified Delphi process will be conducted to achieve consensus on the checklist. A pilot test will be conducted on a selection of the articles selected for the previous systematic review of published microcosting studies. RESULTS: The project is currently in progress. CONCLUSIONS: Standardization of the methods used to conduct, report or appraise microcosting studies will enhance the consistency, transparency, and comparability of future microcosting studies. This will be the first checklist for microcosting studies to accomplish these goals and will be a timely and important contribution to the health economic and health policy literature. In addition to its usefulness to health economists and researchers, it will also benefit journal editors and decision-makers who require accurate cost estimates to deliver health care. PMID- 27707686 TI - Effects of the Web Behavior Change Program for Activity and Multimodal Pain Rehabilitation: Randomized Controlled Trial. AB - BACKGROUND: Web-based interventions with a focus on behavior change have been used for pain management, but studies of Web-based interventions integrated in clinical practice are lacking. To emphasize the development of cognitive skills and behavior, and to increase activity and self-care in rehabilitation, the Web Behavior Change Program for Activity (Web-BCPA) was developed and added to multimodal pain rehabilitation (MMR). OBJECTIVE: The objective of our study was to evaluate the effects of MMR in combination with the Web-BCPA compared with MMR among persons with persistent musculoskeletal pain in primary health care on pain intensity, self-efficacy, and copying, as part of a larger collection of data. Web-BCPA adherence and feasibility, as well as treatment satisfaction, were also investigated. METHODS: A total of 109 participants, mean age 43 (SD 11) years, with persistent pain in the back, neck, shoulder, and/or generalized pain were recruited to a randomized controlled trial with two intervention arms: (1) MMR+WEB (n=60) and (2) MMR (n=49). Participants in the MMR+WEB group self-guided through the eight modules of the Web-BCPA: pain, activity, behavior, stress and thoughts, sleep and negative thoughts, communication and self-esteem, solutions, and maintenance and progress. Data were collected with a questionnaire at baseline and at 4 and 12 months. Outcome measures were pain intensity (Visual Analog Scale), self-efficacy to control pain and to control other symptoms (Arthritis Self-Efficacy Scale), general self-efficacy (General Self-Efficacy Scale), and coping (two-item Coping Strategies Questionnaire; CSQ). Web-BCPA adherence was measured as minutes spent in the program. Satisfaction and Web-BCPA feasibility were assessed by a set of items. RESULTS: Of 109 participants, 99 received the allocated intervention (MMR+WEB: n=55; MMR: n=44); 88 of 99 (82%) completed the baseline and follow-up questionnaires. Intention-to-treat analyses were performed with a sample size of 99. The MMR+WEB intervention was effective over time (time*group) compared to MMR for the two-item CSQ catastrophizing subscale (P=.003), with an effect size of 0.61 (Cohen d) at 12 months. There were no significant between-group differences over time (time*group) regarding pain intensity, self-efficacy (pain, other symptoms, and general), or regarding six subscales of the two-item CSQ. Improvements over time (time) for the whole study group were found regarding mean (P<.001) and maximum (P=.002) pain intensity. The mean time spent in the Web-based program was 304 minutes (range 0-1142). Participants rated the items of Web-BCPA feasibility between 68/100 and 90/100. Participants in the MMR+WEB group were more satisfied with their MMR at 4 months (P<.001) and at 12 months (P=.003). CONCLUSIONS: Adding a self-guided Web-based intervention with a focus on behavioral change for activity to MMR can reduce catastrophizing and increase satisfaction with MMR. Patients in MMR may need more supportive coaching to increase adherence in the Web-BCPA to find it valuable.

PMID- 27707688 TI - A Randomized Controlled Trial Protocol to Evaluate the Effectiveness of an Integrated Care Management Approach to Improve Adherence Among HIV-Infected Patients in Routine Clinical Care: Rationale and Design. AB - BACKGROUND: Adherence to antiretroviral medications is a key determinant of clinical outcomes. Many adherence intervention trials investigated the effects of time-intensive or costly interventions that are not feasible in most clinical care settings. OBJECTIVE: We set out to evaluate a collaborative care approach as a feasible intervention applicable to patients in clinical care including those with mental illness and/or substance use issues. METHODS: We developed a randomized controlled trial (RCT) investigating an integrated, clinic-based care management approach to improve clinical outcomes that could be integrated into the clinical care setting. This is based on the routine integration and systematic follow-up of a clinical assessment of patient-reported outcomes targeting adherence, depression, and substance use, and adapts previously developed and tested care management approaches. The primary health coach or care management role is provided by clinic case managers allowing the intervention to be generalized to other human immunodeficiency virus (HIV) clinics that have case managers. We used a stepped-care approach to target interventions to those at greatest need who are most likely to benefit rather than to everyone to maintain feasibility in a busy clinical care setting. RESULTS: The National Institutes of Health funded this study and had no role in study design, data collection, or decisions regarding whether or not to submit manuscripts for publication. This trial is currently underway, enrollment was completed in 2015, and follow-up time still accruing. First results are expected to be ready for publication in early 2017. DISCUSSION: This paper describes the protocol for an ongoing clinical trial including the design and the rationale for key methodological decisions. There is a need to identify best practices for implementing evidence-based collaborative care models that are effective and feasible in clinical care. Adherence efficacy trials have not led to sufficient improvements, and there remains little guidance regarding how adherence interventions should be implemented into clinical care. By focusing on improving adherence within care settings using existing staff, routine assessment of key domains, such as depression, adherence, and substance use, and feasible interventions, we propose to evaluate this innovative way to improve clinical outcomes.

PMID- 27707691 TI - Optical coherence tomography angiography: an overview of the technology and an assessment of applications for clinical research. AB - In recent years, ophthalmology has experienced significant developments with respect to imaging modalities. Optical coherence tomography angiography is one such technology that seeks to improve diagnostics for retinal diseases. Using standard structural ocular coherence tomography hardware, optical coherence tomography angiography demonstrates the ability to non-invasively visualise the vasculature in the retina and the choroid with high resolution, allowing greater insight into retinal vascular pathologies. In addition, retinal and choroidal vessel density and blood flow can be quantified, offering potential to assist in the diagnosis of a variety of retinal diseases. To date, numerous retinal diseases, such as open-angle glaucoma, have been found to possess a vascular component. Specifically, ischaemia of the optic nerve head and lamina cribrosa has been theorised as a causative factor in ganglion cell death; however, confirmation of this mechanism has been prohibited by the limitations of currently existing imaging modalities. Optical coherence tomography angiography provides clear imaging of these regions and the possibility to elucidate further understanding of vascular factors that contribute to glaucoma development and progression. Furthermore, this imaging modality may provide insight to neural pathologies with vascular components such as Alzheimer's disease. Herein, the authors discuss the theory of operation for optical coherence tomography angiography and the current findings from pilot studies with a focus on open angle glaucoma. In addition, speculation is offered for future applications of the technology to study other diseases with microvascular contributions. PMID- 27707689 TI - Caveolin-3 plays a critical role in autophagy after ischemia-reperfusion. AB - Autophagy is a dynamic recycling process responsible for the breakdown of misfolded proteins and damaged organelles, providing nutrients and energy for cellular renovation and homeostasis. Loss of autophagy is associated with cardiovascular diseases. Caveolin-3 (Cav-3), a muscle-specific isoform, is a structural protein within caveolae and is critical to stress adaptation in the heart. Whether Cav-3 plays a role in regulating autophagy to modulate cardiac stress responses remains unknown. In the present study, we used HL-1 cells, a cardiac muscle cell line, with stable Cav-3 knockdown (Cav-3 KD) and Cav-3 overexpression (Cav-3 OE) to study the impact of Cav-3 in regulation of autophagy. We show that traditional stimulators of autophagy (i.e., rapamycin and starvation) result in upregulation of the process in Cav-3 OE cells while Cav-3 KD cells have a blunted response. Cav-3 coimmunoprecipitated with beclin-1 and Atg12, showing an interaction of caveolin with autophagy-related proteins. In the heart, autophagy may be a major regulator of protection from ischemic stress. We found that Cav-3 KD cells have a decreased expression of autophagy markers [beclin-1, light chain (LC3-II)] after simulated ischemia and ischemia reperfusion (I/R) compared with WT, whereas OE cells showed increased expression. Moreover, Cav-3 KD cells showed increased cell death and higher level of apoptotic proteins (cleaved caspase-3 and cytochrome c) with suppressed mitochondrial function in response to simulated ischemia and I/R, whereas Cav-3 OE cells were protected and had preserved mitochondrial function. Taken together, these results indicate that autophagy regulates adaptation to cardiac stress in a Cav-3-dependent manner. PMID- 27707692 TI - Changes in subfoveal choroidal thickness and reduction of serum levels of vascular endothelial growth factor in patients with POEMS syndrome. AB - AIMS: To determine the changes in the subfoveal choroidal thickness (CT), the foveal thickness (FT) and the serum level of vascular endothelial growth factor (VEGF) after thalidomide treatment in patients with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes (POEMS) syndrome. METHODS: We studied 13 left eyes of 13 treatment-naive patients with POEMS syndrome. The subfoveal CT and FT were determined by enhanced depth imaging optical coherence tomography, and the serum level of VEGF was determined by ELISA at the baseline and at 6 months after thalidomide treatment. The correlations in the serum level of VEGF and the subfoveal CT or the FT at the baseline and at 6 months after treatment were determined. RESULTS: Together with the reduction in the serum level of VEGF, the subfoveal CT was also reduced significantly from 439.1+/-66.5 um at the baseline to 307.2+/-75.4 um at 6 months (p=0.001). The mean FT at the baseline was 236.4+/-30.7 um which did not change significantly at 6 months at 228.1+/-33.1 um (p>0.05). The change in the subfoveal CT was significantly and linearly correlated with the change in the serum level of VEGF at 6 months after treatment (r=0.67, p=0.011). CONCLUSIONS: The significant correlation between the CT and the serum level of VEGF may offer clues on the pathogenesis of ocular diseases of POEMS syndrome and on the role of serum VEGF on the choroid.

AB - Wheeze is a common symptom in young children and is usually associated with viral illnesses. It is a major source of morbidity and is responsible for a high consumption of healthcare and economic resources worldwide. A few children have a condition resembling classical asthma. Rarer specific conditions may have a wheezy component and should be considered in the differential diagnosis. Over the last half century, there have been many circular discussions about the best way of managing preschool wheeze. In general, intermittent wheezing should be treated with intermittent bronchodilator therapy, and a controller therapy should be prescribed for a young child with recurrent wheezing only if positively indicated, and only then if carefully monitored for efficacy. Good multidisciplinary support, attention to environmental exposition and education are essential in managing this common condition. This article analyses the pathophysiological basis of wheezing in infancy and critically discusses the evolution of the scientific progress over time in this unique field of respiratory medicine.

AB - BACKGROUND: Consumption of sugar, specifically sugar-sweetened beverages, has been widely held responsible by the media for the global rise in Type 2 diabetes (T2DM). SOURCES OF DATA: Systematic reviews and dietary guidelines relating dietary sugars to T2DM. AREAS OF AGREEMENT: Weight gain and T2DM incidence are associated with diet and lifestyle patterns characterized by high consumptions of any sweetened beverages. High sugar intakes impair risk factors for macrovascular complications of T2DM. AREAS OF CONTROVERSY: Much of the association between sugars and T2DM is eliminated by adjusting data for body mass index (BMI). However, BMI adjustment does not fully account for adiposity (r2=0.65-0.75). Excess sugar can promote weight gain, thus T2DM, through extra calories, but has no unique diabetogenic effect at physiological levels. GROWING POINTS: Ethical concerns about caffeine added to sweetened beverages, undetectable by consumers, to increase consumption. AREAS TIMELY FOR DEVELOPING RESEARCH: Evidence needed for limiting dietary sugar below 10% energy intake. PMID- 27707698 TI - Should all GPs become NHS employees? PMID- 27707699 TI - Effect of transcutaneous electrical acupuncture point stimulation at different frequencies in a rat model of neuropathic pain. AB - BACKGROUND: Acupuncture and related techniques are used worldwide to alleviate pain; however, their mechanisms of action are still not fully understood. In the present study, we investigated the effect of transcutaneous electrical acupuncture point stimulation (TEAS) at different frequencies in a chronic constriction injury (CCI) model of neuropathic pain in rats. METHODS: CCI was induced by ligating the common sciatic nerve, which produced neuropathic pain. 18 male Sprague-Dawley rats with CCI were randomly divided into three groups (n=6 each) that remained untreated (CCI group) or received TEAS at high frequency (CCI+TEAS-H group) or TEAS at low frequency (CCI+TEAS-L group). Rats in the CCI+TEAS-H group received high frequency stimulation (6-9 mA, 100 Hz) at GB34/GV26/ST36; those in the CCI+TEAS-L group received low frequency stimulation (6-9 mA, 2 Hz) at the same points. Rats in the control group had the same electrodes applied but received no stimulation. All three groups were subjected to behavioural studies after treatment. Expression of MU opioid receptors (MORs) in the L3-L5 dorsal root ganglion (DRG) was determined by immunofluorescence staining and Western blotting after treatment. RESULTS: Compared with the untreated CCI group, both mechanical allodynia and thermal hypergesia were significantly attenuated, and MOR expression in the DRG was significantly increased by low frequency TEAS treatment at GB34/GV26/ST36 (p<0.05). In contrast, no significant differences were observed between the CCI and CCI+TEAS-H groups. CONCLUSIONS: The use of low frequency TEAS significantly mitigated neuropathic pain in this rat model, and its analgesic effect is likely mediated by upregulation of MOR expression in the DRG. PMID- 27707700 TI - Cognitive, Linguistic, and Motor Abilities in a Multigenerational Family with Childhood Apraxia of Speech. AB - OBJECTIVE: This study describes the phenotype in a large family with a strong, multigenerational history of severe speech sound disorder (SSD) persisting into adolescence and adulthood in approximately half the cases. Aims were to determine whether a core phenotype, broader than speech, separated persistent from resolved SSD cases; and to ascertain the uniqueness of the phenotype relative to published cases. METHOD: Eleven members of the PM family (9-55 years) were assessed across cognitive, language, literacy, speech, phonological processing, numeracy, and motor domains. Between group comparisons were made using the Mann-Whitney U-test (p < 0.01). Participant performances were compared to normative data using standardized tests and to the limited published data on persistent SSD phenotypes. RESULTS: Significant group differences were evident on multiple speech, language, literacy, phonological processing, and verbal intellect measures without any overlapping scores. Persistent cases performed within the impaired range on multiple measures. Phonological memory impairment and subtle literacy weakness were present in resolved SSD cases. CONCLUSION: A core phenotype distinguished persistent from resolved SSD cases that was characterized by a multiple verbal trait disorder, including Childhood Apraxia of Speech. Several phenotypic differences differentiated the persistent SSD phenotype in the PM family from the few previously reported studies of large families with SSD, including the absence of comorbid dysarthria and marked orofacial apraxia. This study highlights how comprehensive phenotyping can advance the behavioral study of disorders, in addition to forming a solid basis for future genetic and neural studies. PMID- 27707701 TI - Moderate folic acid supplementation and MTHFD1-synthetase deficiency in mice, a model for the R653Q variant, result in embryonic defects and abnormal placental development. AB - BACKGROUND: Moderately high folic acid intake in pregnant women has led to concerns about deleterious effects on the mother and fetus. Common polymorphisms in folate genes, such as methylenetetrahydrofolate dehydrogenase methenyltetrahydrofolate cyclohydrolase-formyltetrahydrofolate synthetase (MTHFD1) R653Q, may modulate the effects of elevated folic acid intake. OBJECTIVES: We investigated the effects of moderate folic acid supplementation on reproductive outcomes and assessed the potential interaction of the supplemented diet with MTHFD1-synthetase (Mthfd1S) deficiency in mice, which is a model for the R653Q variant. DESIGN: Female Mthfd1S+/+ and Mthfd1S+/- mice were fed a folic acid-supplemented diet (FASD) (5-fold higher than recommended) or control diets before mating and during pregnancy. Embryos and placentas were assessed for developmental defects at embryonic day 10.5 (E10.5). Maternal folate and choline metabolites and gene expression in folate-related pathways were examined. RESULTS: The combination of FASD and maternal MTHFD1-synthetase deficiency led to a greater incidence of defects in E10.5 embryos (diet * maternal genotype, P = 0.0016; diet * embryonic genotype, P = 0.054). The methylenetetrahydrofolate reductase (MTHFR) protein and methylation potential [ratio of S adenosylmethionine (major methyl donor):S-adenosylhomocysteine) were reduced in maternal liver. Although 5-methyltetrahydrofolate (methylTHF) was higher in maternal circulation, the methylation potential was lower in embryos. The presence of developmental delays and defects in Mthfd1S+/- embryos was associated with placental defects (P = 0.003). The labyrinth layer failed to form properly in the majority of abnormal placentas, which compromised the integration of the maternal and fetal circulation and presumably the transfer of methylTHF and other nutrients. CONCLUSIONS: Moderately higher folate intake and MTHFD1-synthetase deficiency in pregnant mice result in a lower methylation potential in maternal liver and embryos and a greater incidence of defects in embryos. Although maternal circulating methylTHF was higher, it may not have reached the embryos because of abnormal placental development; abnormal placentas were observed predominantly in abnormally developed embryos. These findings have implications for women with high folate intakes, particularly if they are polymorphic for MTHFD1 R653Q. PMID- 27707702 TI - Accelerometer-measured dose-response for physical activity, sedentary time, and mortality in US adults. AB - BACKGROUND: Moderate-to-vigorous-intensity physical activity is recommended to maintain and improve health, but the mortality benefits of light activity and risk for sedentary time remain uncertain. OBJECTIVES: Using accelerometer-based measures, we 1) described the mortality dose-response for sedentary time and light- and moderate-to-vigorous-intensity activity using restricted cubic splines, and 2) estimated the mortality benefits associated with replacing sedentary time with physical activity, accounting for total activity. DESIGN: US adults (n = 4840) from NHANES (2003-2006) wore an accelerometer for <=7 d and were followed prospectively for mortality. Proportional hazards models were used to estimate adjusted HRs and 95% CIs for mortality associations with time spent sedentary and in light- and moderate-to-vigorous-intensity physical activity. Splines were used to graphically present behavior-mortality relation. Isotemporal models estimated replacement associations for sedentary time, and separate models were fit for low- (<5.8 h total activity/d) and high-active participants to account for nonlinear associations. RESULTS: Over a mean of 6.6 y, 700 deaths occurred. Compared with less-sedentary adults (6 sedentary h/d), those who spent 10 sedentary h/d had 29% greater risk (HR: 1.29; 95% CI: 1.1, 1.5). Compared with those who did less light activity (3 h/d), those who did 5 h of light activity/d had 23% lower risk (HR: 0.77; 95% CI: 0.6, 1.0). There was no association with mortality for sedentary time or light or moderate-to-vigorous activity in highly active adults. In less-active adults, replacing 1 h of sedentary time with either light- or moderate-to-vigorous-intensity activity was associated with 18% and 42% lower mortality, respectively. CONCLUSIONS: Health promotion efforts for physical activity have mostly focused on moderate-to-vigorous activity. However, our findings derived from accelerometer-based measurements suggest that increasing light-intensity activity and reducing sedentary time are also important, particularly for inactive adults. PMID- 27707704 TI - Nephron morphometry in mice and rats using tomographic microscopy. AB - The aim was to quantify the glomerular capillary surface area, the segmental tubular radius, length, and area of single nephrons in mouse and rat kidneys. Multiple 2.5-um-thick serial Epon sections were obtained from three mouse and three rat kidneys for three-dimensional reconstruction of the nephron tubules. Micrographs were aligned for each kidney, and 359 nephrons were traced and their segments localized. Thirty mouse and thirty rat nephrons were selected for further investigation. The luminal radius of each segment was determined by two methods. The luminal surface area was estimated from the radius and length of each segment. High-resolution micrographs were recorded for five rat glomeruli, and the capillary surface area determined. The capillary volume and surface area were corrected for glomerular shrinkage. A positive correlation was found between glomerular capillary area and proximal tubule area. The thickest part of the nephron, i.e., the proximal tubule, was followed by the thinnest part of the nephron, i.e., the descending thin limb, and the diameters of the seven identified nephron segments share the same rank in the two species. The radius and length measurements from mouse and rat nephrons generally share the same pattern; rat tubular radius-to-mouse tubular radius ratio ~ 1.47, and rat tubular length-to-mouse tubular length ratio ~ 2.29, suggesting relatively longer tubules in the rat. The detailed tables of mouse and rat glomerular capillary area and segmental radius, length, and area values may be used to enhance understanding of the associated physiology, including existing steady-state models of the urine concentrating mechanism. PMID- 27707703 TI - The enigma of continual plasma volume expansion in pregnancy: critical role of the renin-angiotensin-aldosterone system. AB - Pregnancy is characterized by avid renal sodium retention and plasma volume expansion in the presence of decreased blood pressure. Decreased maternal blood pressure is a consequence of reduced systemic vascular tone, which results from an increased production of vasodilators [nitric oxide (NO), prostaglandins, and relaxin] and decreased vascular responsiveness to the potent vasoconstrictor (angiotensin II). The kidneys participate in this vasodilatory response, resulting in marked increases in renal plasma flow and glomerular filtration rate (GFR) during pregnancy. In women, sodium retention drives plasma volume expansion (~40%) and is necessary for perfusion of the growing uterus and fetus. For there to be avid sodium retention in the presence of the potent natriuretic influences of increased NO and elevated GFR, there must be modifications of the tubules to prevent salt wasting. The purpose of this review is to summarize these adaptations. PMID- 27707705 TI - A computational model for simulating solute transport and oxygen consumption along the nephrons. AB - The goal of this study was to investigate water and solute transport, with a focus on sodium transport (TNa) and metabolism along individual nephron segments under differing physiological and pathophysiological conditions. To accomplish this goal, we developed a computational model of solute transport and oxygen consumption (QO2 ) along different nephron populations of a rat kidney. The model represents detailed epithelial and paracellular transport processes along both the superficial and juxtamedullary nephrons, with the loop of Henle of each model nephron extending to differing depths of the inner medulla. We used the model to assess how changes in TNa may alter QO2 in different nephron segments and how shifting the TNa sites alters overall kidney QO2 Under baseline conditions, the model predicted a whole kidney TNa/QO2 , which denotes the number of moles of Na+ reabsorbed per moles of O2 consumed, of ~15, with TNa efficiency predicted to be significantly greater in cortical nephron segments than in medullary segments. The TNa/QO2 ratio was generally similar among the superficial and juxtamedullary nephron segments, except for the proximal tubule, where TNa/QO2 was ~20% higher in superficial nephrons, due to the larger luminal flow along the juxtamedullary proximal tubules and the resulting higher, flow-induced transcellular transport. Moreover, the model predicted that an increase in single-nephron glomerular filtration rate does not significantly affect TNa/QO2 in the proximal tubules but generally increases TNa/QO2 along downstream segments. The latter result can be attributed to the generally higher luminal [Na+], which raises paracellular TNa Consequently, vulnerable medullary segments, such as the S3 segment and medullary thick ascending limb, may be relatively protected from flow-induced increases in QO2 under pathophysiological conditions. PMID- 27707707 TI - Insulin resistance in chronic kidney disease: a systematic review. AB - Insulin resistance (IR) is an early metabolic alteration in chronic kidney disease (CKD) patients, being apparent when the glomerular filtration rate is still within the normal range and becoming almost universal in those who reach the end stage of kidney failure. The skeletal muscle represents the primary site of IR in CKD, and alterations at sites beyond the insulin receptor are recognized as the main defect underlying IR in this condition. Estimates of IR based on fasting insulin concentration are easier and faster but may not be adequate in patients with CKD because renal insufficiency reduces insulin catabolism. The hyperinsulinemic euglycemic clamp is the gold standard for the assessment of insulin sensitivity because this technique allows a direct measure of skeletal muscle sensitivity to insulin. The etiology of IR in CKD is multifactorial in nature and may be secondary to disturbances that are prominent in renal diseases, including physical inactivity, chronic inflammation, oxidative stress, vitamin D deficiency, metabolic acidosis, anemia, adipokine derangement, and altered gut microbiome. IR contributes to the progression of renal disease by worsening renal hemodynamics by various mechanisms, including activation of the sympathetic nervous system, sodium retention, and downregulation of the natriuretic peptide system. IR has been solidly associated with intermediate mechanisms leading to cardiovascular (CV) disease in CKD including left ventricular hypertrophy, vascular dysfunction, and atherosclerosis. However, it remains unclear whether IR is an independent predictor of mortality and CV complications in CKD. Because IR is a modifiable risk factor and its reduction may lower CV morbidity and mortality, unveiling the molecular mechanisms responsible for the pathogenesis of CKD-related insulin resistance is of importance for the identification of novel therapeutic targets aimed at reducing the high CV risk of this condition.

PMID- 27707708 TI - Collecting duct-specific knockout of nitric oxide synthase 3 impairs water excretion in a sex-dependent manner. AB - Nitric oxide (NO) inhibits collecting duct (CD) Na+ and water reabsorption. Mice with CD-specific knockout (KO) of NO synthase 1 (NOS1) have salt-sensitive hypertension. In contrast, the role of NOS3 in CD salt and water reabsorption is unknown. Mice with CD NOS3 KO were generated with loxP-flanked exons 9-12 (encodes the calmodulin binding site) of the NOS3 gene and the aquaporin-2 promoter-Cre transgene. There were no differences between control and CD NOS3 KO mice, irrespective of sex, in food intake, water intake, urine volume, urinary Na+ or K+ excretion, plasma renin concentration, blood pressure, or pulse during 7 days of normal (0.3%), high (3.17%), or low (0.03%) Na+ intake. Blood pressure was similar between genotypes during DOCA-high salt. CD NOS3 KO did not alter urine volume or urine osmolality after water deprivation. In contrast, CD NOS3 KO male, but not female, mice had lower urine volume and higher urine osmolality over the course of 7 days of water loading compared with control mice. Male, but not female, CD NOS3 KO mice had reduced urinary nitrite+nitrate excretion compared with controls after 7 days of water loading. Urine AVP and AVP stimulated cAMP accumulation in isolated inner medullary CD were similar between genotypes. Western analysis did not reveal a significant effect of CD NOS3 KO on renal aquaporin expression. In summary, these data suggest that CD NOS3 may be involved in the diuretic response to a water load in a sex-specific manner; the mechanism of this effect remains to be determined. PMID- 27707706 TI - Solute transport and oxygen consumption along the nephrons: effects of Na+ transport inhibitors. AB - Sodium and its associated anions are the major determinant of extracellular fluid volume, and the reabsorption of Na+ by the kidney plays a crucial role in long term blood pressure control. The goal of this study was to investigate the extent to which inhibitors of transepithelial Na+ transport (TNa) along the nephron alter urinary solute excretion and TNa efficiency and how those effects may vary along different nephron segments. To accomplish that goal, we used the multinephron model developed in the companion study (28). That model represents detailed transcellular and paracellular transport processes along the nephrons of a rat kidney. We simulated the inhibition of the Na+/H+ exchanger (NHE3), the bumetanide-sensitive Na+-K+-2Cl- transporter (NKCC2), the Na+-Cl- cotransporter (NCC), and the amiloride-sensitive Na+ channel (ENaC). Under baseline conditions, NHE3, NKCC2, NCC, and ENaC reabsorb 36, 22, 4, and 7%, respectively, of filtered Na+ The model predicted that inhibition of NHE3 substantially reduced proximal tubule TNa and oxygen consumption (QO2 ). Whole-kidney TNa efficiency, as reflected by the number of moles of Na+ reabsorbed per moles of O2 consumed (denoted by the ratio TNa/QO2 ), decreased by ~20% with 80% inhibition of NHE3. NKCC2 inhibition simulations predicted a substantial reduction in thick ascending limb TNa and QO2 ; however, the effect on whole-kidney TNa/QO2 was minor. Tubular K+ transport was also substantially impaired, resulting in elevated urinary K+ excretion. The most notable effect of NCC inhibition was to increase the excretion of Na+, K+, and Cl-; its impact on whole-kidney TNa and its efficiency was minor. Inhibition of ENaC was predicted to have opposite effects on the excretion of Na+ (increased) and K+ (decreased) and to have only a minor impact on whole-kidney TNa and TNa/QO2 Overall, model predictions agree well with measured changes in Na+ and K+ excretion in response to diuretics and Na+ transporter mutations. PMID- 27707711 TI - Embryo Mortality Around the Period of Maintenance of the Corpus Luteum Causes Alterations to the Ovarian Function of Lactating Dairy Cows. AB - Objectives were to identify cows with embryo mortality (EM) around the period of corpus luteum maintenance by interferon tau (IFNT) and to characterize ovarian function in cows that underwent EM. Lactating Holstein cows received artificial insemination (AI) (Day = 0) with semen or extender only. From Day 14 to 42 transrectal ultrasonography was performed daily to monitor ovarian dynamics and uterine contents whereas blood was collected every 48 h to determine ISG15 and MX2 mRNA abundance in blood mononuclear cells (Day 14 to 22 only) and determination of hormone concentrations. Cows were classified in the following reproductive status groups: cyclic (inseminated with extender; n = 15), pregnant (embryo present on Day 42; n = 23), no embryo (n = 23), and EM (n = 14). EM was defined as the presence of an embryo based on interferon-stimulated genes (ISG) mRNA abundance and concentrations of pregnancy-specific protein B (PSPB) above specific cutoff points but no embryo visualized by ultrasonography. Within the EM group, early EM (up to Day 22) was when ISG fold changes were above specific cutoff points from Day 18 to 22 and PSPB below 0.7 ng/ml on and after Day 24, whereas late EM (after Day 22) was when PSPB was above 0.7 ng/ml on or after Day 24 regardless of ISG expression. This experiment provided evidence that the combination of ISG expression patterns and PSPB concentrations is a reasonable method to determine EM around the period of corpus luteum maintenance by IFNT because cows with evidence of EM had patterns of ISG expression more similar to pregnant than cyclic cows or cows with no embryo. Within the EM group, only cows with late EM had delayed luteal regression and longer interovulatory intervals. No major alterations in follicular function were observed after the onset of luteolysis. Our results suggest that embryo development needs to continue beyond 22 days after AI to effectively prevent luteolysis and extend the luteal phase. PMID- 27707712 TI - Sperm-Coating Beta-Defensin 126 Is a Dissociation-Resistant Dimer Produced by Epididymal Epithelium in the Bovine Reproductive Tract. AB - Beta-defensins are innate immune molecules, often described as antimicrobial peptides because of their bactericidal activity and are now known to have diverse additional functions, including cell signaling, chemoattraction, immunoregulation, and reproduction. In humans and primates, beta-defensin 126 has been shown to regulate the ability of sperm to swim through cervical mucus and to protect sperm from attack by the female immune system during transit toward the oviduct. Bovine beta-defensin 126 (BBD126) is the ortholog of human defensin 126, and computational analysis here revealed significant conservation between BBD126 and other mammalian orthologs at the N-terminus, although extensive sequence differences were detected at the C-terminus, implying possible species-specific roles for this beta-defensin in reproduction. We had previously demonstrated preferential expression of this and related beta-defensin genes in the bovine male reproductive tract, but no studies of bovine beta-defensin proteins have been performed to date. Here, we analyzed BBD126 protein using a monoclonal antibody (a-BBD126) generated against a 14 amino acid peptide sequence from the secreted fragment of BBD126. The specificity of a-BBD126 was validated by testing against the native form of the peptide recovered from bovine caudal epididymal fluid and recombinant BBD126 generated using a prokaryotic expression system. Western blot analysis of the native and recombinant forms showed that BBD126 exists as a dimer that was highly resistant to standard methods of dissociation. Immunohistochemical staining using a-BBD126 demonstrated BBD126 protein expression by epithelial cells of the caudal epididymis and vas deferens from both mature and immature bulls. BBD126 could also be seen (by confocal microscopy) to coat caudal sperm, with staining concentrated on the tail of the sperm cells. This study is the first to demonstrate beta-defensin 126 protein expression in the bovine reproductive tract and on bull sperm. Its dissociation resistant dimeric structure is likely to have important functional implications for the role of BBD126 in bovine reproduction. PMID- 27707714 TI - The problem with "abstinence is unnecessary". PMID- 27707713 TI - Cauda Epididymis-Specific Beta-Defensin 126 Promotes Sperm Motility but Not Fertilizing Ability in Cattle. AB - Bovine beta-defensin 126 (BBD126) exhibits preferential expression for the cauda epididymis of males, where it is absorbed onto the tail and postacrosomal region of the sperm. The aim of this study was to examine the role of BBD126 in bull sperm function. Fresh and frozen-thawed semen were incubated in the presence of different capacitating agents as well as with phosphatidylinositol-specific phospholipase C. These treatments, which have been successful in releasing beta defensin 126 from macaque sperm, proved to be ineffective in bull sperm. This finding suggests that the protein behaves in a different manner in the bovine. The lack of success in removing BBD126 led us to use corpus epididymis sperm, a model in which the protein is not present, to study its functional role. Corpus sperm were incubated with cauda epididymal fluid (CEF) in the absence or presence of BBD126 antibody or with recombinant BBD126 (rBBD126). Confocal microscopy revealed that rBBD126 binds to corpus sperm with the same pattern observed for BBD126 in cauda sperm, whereas an aberrant binding pattern is observed when sperm are subject to CEF incubation. Addition of CEF increased motility as well as the number of corpus sperm migrating through cervical mucus from estrus cows. However, it decreased the ability of sperm to fertilize in vitro matured oocytes. The presence of the antibody failed to abrogate these effects. Furthermore, when rBBD126 was added in the absence of other factors and proteins from the CEF, an increase in motility was also observed and no negative effects in fertility were seen. These results suggest that BBD126 plays a key role in the acquisition of sperm motility in the epididymis. PMID- 27707715 TI - Mental illness is not a state of mind.

AB - Circadian clocks influence virtually all physiological processes, including lactation. Here, we investigate the role of the CLOCK gene in regulation of mammary epithelial cell growth and differentiation. Comparison of mammary morphology in late-pregnant wild-type and ClockDelta19 mice, showed that gland development was negatively impacted by genetic loss of a functional timing system. To understand whether these effects were due, in part, to loss of CLOCK function in the gland, the mouse mammary epithelial cell line, HC11, was transfected with short hairpin RNA that targeted Clock (shClock). Cells transfected with shClock expressed 70% less Clock mRNA than wild-type (WT) HC11 cultures, which resulted in significantly depressed levels of CLOCK protein (P < 0.05). HC11 lines carrying shClock had four-fold higher growth rates (P < 0.05), and the percentage of cells in G1 phase was significantly higher (90.1 +/- 1.1% of shClock vs. 71.3 +/- 3.6% of WT-HC11) following serum starvation. Quantitative PCR (qPCR) analysis showed shClock had significant effects (P < 0.0001) on relative expression levels of Ccnd1, Wee1, and Tp63 qPCR analysis of the effect of shClock on Fasn and Cdh1 expression in undifferentiated cultures and cultures treated 96 h with dexamethasone, insulin, and prolactin (differentiated) found levels were reduced by twofold and threefold, respectively (P < 0.05), in shClock line relative to WT cultures. Abundance of CDH1 and TP63 proteins were significantly reduced in cultures transfected with shClock These data support how CLOCK plays a role in regulation of epithelial cell growth and differentiation in the mammary gland. PMID- 27707718 TI - Developmental plasticity of mitochondrial function in American alligators, Alligator mississippiensis. AB - The effect of hypoxia on cellular metabolism is well documented in adult vertebrates, but information is entirely lacking for embryonic organisms. The effect of hypoxia on embryonic physiology is particularly interesting, as metabolic responses during development may have life-long consequences, due to developmental plasticity. To this end, we investigated the effects of chronic developmental hypoxia on cardiac mitochondrial function in embryonic and juvenile American alligators (Alligator mississippiensis). Alligator eggs were incubated in 21% or 10% oxygen from 20 to 90% of embryonic development. Embryos were either harvested at 90% development or allowed to hatch and then reared in 21% oxygen for 3 yr. Ventricular mitochondria were isolated from embryonic/juvenile alligator hearts. Mitochondrial respiration and enzymatic activities of electron transport chain complexes were measured with a microrespirometer and spectrophotometer, respectively. Developmental hypoxia induced growth restriction and increased relative heart mass, and this phenotype persisted into juvenile life. Embryonic mitochondrial function was not affected by developmental hypoxia, but at the juvenile life stage, animals from hypoxic incubations had lower levels of Leak respiration and higher respiratory control ratios, which is indicative of enhanced mitochondrial efficiency. Our results suggest developmental hypoxia can have life-long consequences for alligator morphology and metabolic function. Further investigations are necessary to reveal the adaptive significance of the enhanced mitochondrial efficiency in the hypoxic phenotype. PMID- 27707719 TI - P2X7 receptors in body temperature, locomotor activity, and brain mRNA and lncRNA responses to sleep deprivation. AB - The ionotropic purine type 2X7 receptor (P2X7R) is a nonspecific cation channel implicated in sleep regulation and brain cytokine release. Many endogenous rhythms covary with sleep, including locomotor activity and core body temperature. Furthermore, brain-hypothalamic cytokines and purines play a role in the regulation of these physiological parameters as well as sleep. We hypothesized that these parameters are also affected by the absence of the P2X7 receptor. Herein, we determine spontaneous expression of body temperature and locomotor activity in wild-type (WT) and P2X7R knockout (KO) mice and how they are affected by sleep deprivation (SD). We also compare hypothalamic, hippocampal, and cortical cytokine- and purine-related receptor and enzyme mRNA expressions before and after SD in WT and P2X7RKO mice. Next, in a hypothesis generating survey of hypothalamic long noncoding (lnc) RNAs, we compare lncRNA expression levels between strains and after SD. During baseline conditions, P2X7RKO mice had attenuated temperature rhythms compared with WT mice, although locomotor activity patterns were similar in both strains. After 6 h of SD, body temperature and locomotion were enhanced to a greater extent in P2X7RKO mice than in WT mice during the initial 2-3 h after SD. Baseline mRNA levels of cortical TNF-alpha and P2X4R were higher in the KO mice than WT mice. In response to SD, the KO mice failed to increase hypothalamic adenosine deaminase and P2X4R mRNAs. Further, hypothalamic lncRNA expressions varied by strain, and with SD. Current data are consistent with a role for the P2X7R in thermoregulation and lncRNA involvement in purinergic signaling. PMID- 27707721 TI - Breathing while altricial: the ontogeny of ventilatory chemosensitivity in red winged blackbird (Agelaius phoeniceus) nestlings. AB - Altricial bird species, like red-winged blackbirds, hatch at an immature state of functional maturity with limited aerobic capacity and no endothermic capacity. Over the next 10-12 days in the nest, red-winged blackbirds develop increased metabolic capacity before fledging. Although ontogeny of respiration has been described in precocial birds, ontogeny of ventilatory chemosensitivity is unknown in altricial species. Here we examined developmental changes in chemosensitivity of tidal volume (Vt), breathing frequency (f), minute ventilation (Ve), and whole animal oxygen consumption (Vo2) from hatching to just before fledging in red winged blackbirds on days 1, 3, 5, 7, and 9 posthatching (dph) in response to hypercapnia (2 and 4% CO2) and hypoxia (15 and 10% O2). Under control conditions, there was a developmental increase in Ve with age due to increased Vt Hypercapnic and hypoxic chemosensitivities were present as early as 1 dph. In response to hypoxia, 1, 3, and 9 dph nestlings increased Ve at 10% O2, by increasing f with some change in Vt in younger animals. In contrast to early neonatal altricial mammals, the hypoxic response of nestling red-winged blackbirds was not biphasic. In response to hypercapnia, 3 dph nestlings increased Ve by increasing both f and Vt From 5 dph on, the hypercapnic increase in Ve was accounted for by increased Vt and not f. Chemosensitivity to O2 and CO2 matures early in nestling red-winged blackbirds, well before the ability to increase Vo2 in response to cooling, and thus does not represent a limitation to the development of endothermy. PMID- 27707720 TI - Imatinib attenuates cerebrovascular injury and phenotypic transformation after intracerebral hemorrhage in rats. AB - This study explored the hypothesis that intracerebral hemorrhage (ICH) promotes release of diffusible factors that can significantly influence the structure and function of cerebral arteries remote from the site of injury, through action on platelet-derived growth factor (PDGF) receptors. Four groups of adult male Sprague-Dawley rats were studied (n = 8 each): 1) sham; 2) sham + 60 mg/kg ip imatinib; 3) ICH (collagenase method); and 4) ICH + 60 mg/kg ip imatinib given 60 min after injury. At 24 h after injury, sham artery passive diameters (+3 mM EGTA) averaged 244 +/- 7 um (at 60 mmHg). ICH significantly increased passive diameters up to 6.4% and decreased compliance up to 42.5%. For both pressure- and potassium-induced contractions, ICH decreased calcium mobilization up to 26.2% and increased myofilament calcium sensitivity up to 48.4%. ICH reduced confocal colocalization of smooth muscle alpha-actin (alphaActin) with nonmuscle myosin heavy chain (MHC) and increased its colocalization with smooth muscle MHC, suggesting that ICH promoted contractile differentiation. ICH also enhanced colocalization of myosin light chain kinase (MLCK) with both alphaActin and regulatory 20-kDa myosin light chain. All effects of ICH on passive diameter, compliance, contractility, and contractile protein colocalization were significantly reduced or absent in arteries from animals treated with imatinib. These findings support the hypothesis that ICH promotes release into the cerebrospinal fluid of vasoactive factors that can diffuse to and promote activation of cerebrovascular PDGF receptors, thereby altering the structure, contractile protein organization, contractility, and smooth muscle phenotype of cerebral arteries remote from the site of hemorrhage. PMID- 27707722 TI - Vagal afferent activation induces salivation and swallowing-like events in anesthetized rats. AB - The aim of this study was to clarify the effect of vagal afferent activation on salivation and swallowing-like events. Salivation is part of a reflex induced by stimulation of the oral area during feeding or chewing. Recently, we reported that nausea induced by gastroesophageal reflux (GER) activation produced salivation and swallowing in humans. Here, we investigated the ability of visceral sensation to enhance salivation and swallowing in rodents in order to inform the mechanism of GER-mediated stomatognathic activation. First, we administered LiCl to anesthetized male rats to induce nausea. LiCl significantly increased salivation and increased the activity of the vagal afferent nerve. Next, we simultaneously recorded salivation and swallowing using an electrode attached to the mylohyoid muscle during vagal afferent stimulation in a physiological range of frequencies. Vagal afferent stimulation significantly increased salivation and swallowing-like events in a frequency-dependent manner. A muscle relaxant, vecuronium bromide, diminished the swallowing-like response but did not affect salivation. These results indicate that visceral sensation induces salivation and swallowing-like events in anesthetized rodents through vagal afferent activation.

PMID- 27707723 TI - Acute hot water immersion is protective against impaired vascular function following forearm ischemia-reperfusion in young healthy humans. AB - Ischemia-reperfusion (I/R) injury is a primary cause of poor outcomes following ischemic cardiovascular events. We tested whether acute hot water immersion protects against forearm vascular I/R. Ten (5 male, 5 female) young (23 +/- 2 yr), healthy subjects participated in two trials in random order 7-21 days apart, involving: 1) 60 min of seated rest (control), or 2) 60 min of immersion in 40.5 degrees C water (peak rectal temperature: 38.9 +/- 0.2 degrees C). I/R was achieved 70 min following each intervention by inflating an upper arm cuff to 250 mmHg for 20 min followed by 20 min of reperfusion. Brachial artery flow-mediated dilation (FMD) and forearm postocclusive reactive hyperemia (RH) were measured as markers of macrovascular and microvascular function at three time points: 1) preintervention, 2) 60 min postintervention, and 3) post-I/R. Neither time control nor hot water immersion alone affected FMD (both, P > 0.99). I/R reduced FMD from 7.4 +/- 0.7 to 5.4 +/- 0.6% (P = 0.03), and this reduction was prevented following hot water immersion (7.0 +/- 0.7 to 7.7 +/- 1.0%; P > 0.99). I/R also impaired RH (peak vascular conductance: 2.6 +/- 0.5 to 2.0 +/- 0.4 ml.min-1.mmHg 1, P = 0.003), resulting in a reduced shear stimulus (SRAUC.10-3: 22.5 +/- 2.4 to 16.9 +/- 2.4, P = 0.04). The post-I/R reduction in peak RH was prevented by hot water immersion (2.5 +/- 0.4 to 2.3 +/- 0.4 ml.min-1.mmHg-1; P = 0.33). We observed a decline in brachial artery dilator function post-I/R, which may be (partly) related to damage incurred downstream in the microvasculature, as indicated by impaired RH and shear stimulus. Hot water immersion was protective against reductions in FMD and RH post-I/R, suggesting heat stress induces vascular changes consistent with reducing I/R injury following ischemic events. PMID- 27707724 TI - Hyperinsulinemic-normoglycemic clamp administered together with amino acids induces anabolism after cardiac surgery. AB - Cardiac surgery triggers an inflammatory stress response, leading to protein catabolism, a process that even high-dose insulin therapy alone cannot reverse. To determine whether hyperinsulinemic-normoglycemic clamp and perioperative amino acid (AA) supplementation improves whole body protein balance, 20 patients scheduled for elective coronary artery bypass grafting surgery were randomly assigned to have intra- and postoperative hyperinsulinemic-normoglycemic clamp, with or without intravenous AA supplementation. Primed continuous infusions of [6,6-2H2]glucose and l-[1-13C]leucine were used to quantify whole body protein and glucose metabolism before and after surgery. Adipose tissue and serum cytokines were also analyzed to measure their responsiveness to the anabolic effect of AA administration. During hyperinsulinemic-normoglycemic clamp, AA supplementation successfully stimulated whole body protein synthesis, resulting in a positive whole body protein balance after surgery (insulin: -13.6 +/- 4.5 vs. insulin + AA: 2.1 +/- 5.4 MUmol.kg-1.h-1, P < 0.001). Endogenous glucose production was equally suppressed in both groups (insulin: 0.0 +/- 3.8 vs. insulin + AA 1.6 +/- 1.6 MUmol.kg-1.min-1, P = 0.230). AA supplementation led to significant changes in serum and tissue IL-6 (insulin: 246.6 +/- 111.2 vs. insulin + AA: 124.5 +/- 79.3 pg/ml, P = 0.011). In conclusion, hyperinsulinemic normoglycemic clamp technique, together with AA supplementation, can induce an anabolic state after open-heart surgery, as quantified by a positive whole body protein balance.

AB - Cryopyrin-associated periodic syndrome (CAPS) is a rare, heterogeneous disease entity associated with NLRP3 gene mutations and increased interleukin-1 (IL-1) secretion. Early diagnosis and rapid initiation of IL-1 inhibition prevent organ damage. The aim of the study was to develop and validate diagnostic criteria for CAPS. An innovative process was followed including interdisciplinary team building, item generation: review of CAPS registries, systematic literature review, expert surveys, consensus conferences for item refinement, item reduction and weighting using 1000Minds decision software. Resulting CAPS criteria were tested in large cohorts of CAPS cases and controls using correspondence analysis. Diagnostic models were explored using sensitivity analyses. The international team included 16 experts. Systematic literature and registry review identified 33 CAPS-typical items; the consensus conferences reduced these to 14. 1000Minds exercises ranked variables based on importance for the diagnosis. Correspondence analysis determined variables consistently associated with the diagnosis of CAPS using 284 cases and 837 controls. Seven variables were significantly associated with CAPS (p<0.001). The best diagnosis model included: Raised inflammatory markers (C-reactive protein/serum amyloid A) plus >=two of six CAPS-typical symptoms: urticaria-like rash, cold-triggered episodes, sensorineural hearing loss, musculoskeletal symptoms, chronic aseptic meningitis and skeletal abnormalities. Sensitivity was 81%, specificity 94%. It performed well for all CAPS subtypes and regardless of NLRP3 mutation. The novel approach integrated traditional methods of evidence synthesis with expert consensus, web-based decision tools and innovative statistical methods and may serve as model for other rare diseases. These criteria will enable a rapid diagnosis for children and adults with CAPS. PMID- 27707731 TI - Remission in SLE: the duration depends on multiple factors, including the definition. PMID- 27707730 TI - Discordance between tender and swollen joint count as well as patient's and evaluator's global assessment may reduce likelihood of remission in patients with rheumatoid arthritis and psoriatic arthritis: data from the prospective multicentre NOR-DMARD study. AB - OBJECTIVE: To investigate the predictive value of discordance between (1) tender and swollen joint count and (2) patient's and evaluator's global assessment on remission in patients with rheumatoid arthritis (RA) and psoriatic arthritis (PsA). METHODS: From the prospective, multicentre Norwegian-Disease-Modifying Antirheumatic Drug study, we included patients with RA and PsA starting first time tumour necrosis factor inhibitors and DMARD-naive patients starting methotrexate between 2000 and 2012. The predictive value of DeltaTSJ (tender minus swollen joint counts) and DeltaPEG (patient's minus evaluator's global assessment) on remission was explored in prespecified logistic regression models adjusted for age, sex, disease duration and smoking. RESULTS: A total of 2735 patients with RA and 1236 patients with PsA were included (mean (SD) age 55.0 (13.5)/48.3 (12.4) years, median(range) disease duration 0.7 (0.0-58.0)/1.3 (0.0 48.3) years, 69.7/48.4% females). Baseline DeltaTSJ/DeltaPEG reduced the likelihood of achieving DAS28<2.6, SDAI<=3.3, CDAI<=2.8, ACR/EULAR Boolean and DAPSA<4 remission after 3 and 6 months in RA (OR 0.95-0.97, p<0.001/OR 0.96-0.99, p<=0.01) and PsA (OR 0.91-0.94, p<=0.004/OR 0.89-0.99, p<=0.002), except for DeltaPEG and 6-month DAS28 remission in PsA. CONCLUSIONS: Discordance between patient's and physician's evaluation of disease activity reflected through DeltaTSJ and partly DeltaPEG may reduce likelihood of remission in RA and PsA. The findings are relevant for use of the treat-to-target strategy in individual patients. PMID- 27707732 TI - Tight foreskin. PMID- 27707733 TI - Independent or employed? There is a third way. . .

AB - Exome sequencing studies in chronic myelomonocytic leukemia (CMML) illustrate a mutational landscape characterized by few somatic mutations involving a subset of recurrent gene mutations in ASXL1, SRSF2, and TET2, each approaching 40% in incidence. This has led to the clinical implementation of next-generation sequencing panels that effectively identify clonal monocytosis and complement clinical prognostic scoring systems in most patients. However, most murine models based on single gene mutations fail to recapitulate the CMML phenotype, and many gene mutations are loss of function, making the identification of traditional therapeutic vulnerabilities challenging. Further, as a subtype of the myelodysplastic/myeloproliferative neoplasms, CMML has a complex clinical heterogeneity not reflected by the mutational landscape. In this review, we will discuss the discordance between mutational homogeneity and clinical complexity and highlight novel genomic and nongenomic approaches that offer insight into the underlying clinical characteristics of CMML.

AB - BCL11A, a repressor of human fetal (gamma-)globin expression, is required for immune and hematopoietic stem cell functions and brain development. Regulatory sequences within the gene, which are subject to genetic variation affecting fetal globin expression, display hallmarks of an erythroid enhancer in cell lines and transgenic mice. As such, this enhancer is a novel, attractive target for therapeutic gene editing. To explore the roles of such sequences in vivo, we generated mice in which the orthologous 10-kb intronic sequences were removed. Bcl11a enhancer-deleted mice, Bcl11a(Deltaenh), phenocopy the BCL11A-null state with respect to alterations of globin expression, yet are viable and exhibit no observable blood, brain, or other abnormalities. These preclinical findings provide strong in vivo support for genetic modification of the enhancer for therapy of hemoglobin disorders. PMID- 27707738 TI - Consensus on Exercise Reporting Template (CERT): Explanation and Elaboration Statement. AB - Exercise is effective for prevention and management of acute and chronic health conditions. However, trial descriptions of exercise interventions are often suboptimal, leaving readers unclear about the content of effective programmes. To address this, the 16-item internationally endorsed Consensus on Exercise Reporting Template (CERT) was developed. The aim is to present the final template and provide an Explanation and Elaboration Statement to operationalise the CERT. Development of the CERT was based on the EQUATOR Network methodological framework for developing reporting guidelines. We used a modified Delphi technique to gain consensus of international exercise experts and conducted 3 sequential rounds of anonymous online questionnaires and a Delphi workshop. The 16-item CERT is the minimum data set considered necessary to report exercise interventions. The contents may be included in online supplementary material, published as a protocol or located on websites and other electronic repositories. The Explanation and Elaboration Statement is intended to enhance the use, understanding and dissemination of the CERT and presents the meaning and rationale for each item, together with examples of good reporting. The CERT is designed specifically for the reporting of exercise programmes across all evaluative study designs for exercise research. The CERT can be used by authors to structure intervention reports, by reviewers and editors to assess completeness of exercise descriptions and by readers to facilitate the use of the published information. The CERT has the potential to increase clinical uptake of effective exercise programmes, enable research replication, reduce research waste and improve patient outcomes. PMID- 27707739 TI - Physical activity and exercise for erectile dysfunction: systematic review and meta-analysis. AB - BACKGROUND: A growing body of evidence suggests that physical activity and exercise may improve erectile function. OBJECTIVE: To conduct a systematic review and meta-analysis evaluating the effects of physical activity modalities and exercise on erectile function in erectile dysfunction trials. METHODS: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. We searched 6 electronic databases between January 1990 and July 2016 and hand-searched reference lists for randomised controlled trials. Only patients with a diagnosis of erectile dysfunction were included. The mean differences between intervention and control groups were calculated for meta-analysis. RESULTS: 7 studies were eligible, including 478 participants allocated to aerobic, pelvic or combined exercise interventions. Follow-up ranged from 8 weeks to 2 years. The risk of bias in the trials was deemed moderate to high mainly due to impossible blinding of patients and personnel, as well as questionable blinding of outcome assessors. Random-effects meta-analyses were performed. Pooled data showed a statistically significant improvement in erectile function score (mean difference 3.85, 95% CI 2.33 to 5.37). A benefit was still demonstrable after a sensitivity analysis because the mean difference in International Index of Erectile Function (IIEF) score ranged from 3.39 (95% CI 1.92 to 4.87) to 4.28 (95% CI 2.54 to 6.02). A benefit was also detected in short-term and long-term interventions as well as in trials evaluating physical activity and exercise alone or in addition to usual care. CONCLUSIONS: The present study suggests that physical activity and exercise interventions improve patient-reported erectile dysfunction, particularly aerobic exercise with moderate-to-vigorous intensity.

This study aimed to test whether this effect is still present when new trials are added, and it explores whether characteristics of the trial design, sample or intervention are associated with greater fall prevention effects. DESIGN: Update of a systematic review with random effects meta-analysis and meta-regression. DATA SOURCES: Cochrane Library, CINAHL, MEDLINE, EMBASE, PubMed, PEDro and SafetyLit were searched from January 2010 to January 2016. STUDY ELIGIBILITY CRITERIA: We included randomised controlled trials that compared fall rates in older people randomised to receive exercise as a single intervention with fall rates in those randomised to a control group. RESULTS: 99 comparisons from 88 trials with 19 478 participants were available for meta analysis. Overall, exercise reduced the rate of falls in community-dwelling older people by 21% (pooled rate ratio 0.79, 95% CI 0.73 to 0.85, p<0.001, I2 47%, 69 comparisons) with greater effects seen from exercise programmes that challenged balance and involved more than 3 hours/week of exercise. These variables explained 76% of the between-trial heterogeneity and in combination led to a 39% reduction in falls (incident rate ratio 0.61, 95% CI 0.53 to 0.72, p<0.001). Exercise also had a fall prevention effect in community-dwelling people with Parkinson's disease (pooled rate ratio 0.47, 95% CI 0.30 to 0.73, p=0.001, I2 65%, 6 comparisons) or cognitive impairment (pooled rate ratio 0.55, 95% CI 0.37 to 0.83, p=0.004, I2 21%, 3 comparisons). There was no evidence of a fall prevention effect of exercise in residential care settings or among stroke survivors or people recently discharged from hospital. SUMMARY/CONCLUSIONS: Exercise as a single intervention can prevent falls in community-dwelling older people. Exercise programmes that challenge balance and are of a higher dose have larger effects. The impact of exercise as a single intervention in clinical groups and aged care facility residents requires further investigation, but promising results are evident for people with Parkinson's disease and cognitive impairment.

PMID- 27707741 TI - Injuries among weightlifters and powerlifters: a systematic review. AB - BACKGROUND: Olympic weightlifting and powerlifting are two sports that expose the body to great forces. Injury characteristics have not been systematically reviewed for these two growing sports. OBJECTIVE: The purpose of this study was to systematically review the literature regarding various definitions of injuries used, injury localisation, the prevalence and incidence of injuries and the associated risk factors for injuries in weightlifting and powerlifting. DESIGN: Systematic review. DATA SOURCES: Five databases, PubMed, MEDLINE, SPORTDiscus, Scopus and Web of Science, were searched between 9 March and 6 April 2015. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Studies assessing injury incidence and prevalence in Olympic weightlifting and powerlifting were included. The Quality assessment tool for observational cohort and cross-sectional studies was used to assess methodological quality. RESULTS: 9 studies were included in the review. Injury was defined fairly consistently across studies. Most studies were of low methodological quality. The spine, shoulder and the knee were the most common injury localisations in both sports. The injury incidence in weightlifting was 2.4-3.3 injuries/1000 hours of training and 1.0-4.4 injuries/1000 hours of training in powerlifting. Only one retrospective study had analysed possible risk factors. SUMMARY/CONCLUSIONS: The risk of injury in both sports were similar to other non-contact sports also requiring strength/power, but low compared to contact sports. The severity of injuries differed in the included studies. Since little has been studied regarding possible risk factors to injuries, further research is therefore warranted to explain why athletes get injured and how to prevent injuries.

AB - BACKGROUND: Because soil salinity is a major abiotic constraint affecting crop yield, much research has been conducted to develop plants with improved salinity tolerance. Salinity stress impacts many aspects of a plant's physiology, making it difficult to study in toto Instead, it is more tractable to dissect the plant's response into traits that are hypothesized to be involved in the overall tolerance of the plant to salinity. SCOPE AND CONCLUSIONS: We discuss how to quantify the impact of salinity on different traits, such as relative growth rate, water relations, transpiration, transpiration use efficiency, ionic relations, photosynthesis, senescence, yield and yield components. We also suggest some guidelines to assist with the selection of appropriate experimental systems, imposition of salinity stress, and obtaining and analysing relevant physiological data using appropriate indices. We illustrate how these indices can be used to identify relationships amongst the proposed traits to identify which traits are the most important contributors to salinity tolerance. Salinity tolerance is complex and involves many genes, but progress has been made in studying the mechanisms underlying a plant's response to salinity. Nevertheless, several previous studies on salinity tolerance could have benefited from improved experimental design. We hope that this paper will provide pertinent information to researchers on performing proficient assays and interpreting results from salinity tolerance experiments. PMID- 27707747 TI - Gene conversion events and variable degree of homogenization of rDNA loci in cultivars of Brassica napus. AB - BACKGROUND AND AIMS: Brassica napus (AACC, 2n = 38, oilseed rape) is a relatively recent allotetraploid species derived from the putative progenitor diploid species Brassica rapa (AA, 2n = 20) and Brassica oleracea (CC, 2n = 18). To determine the influence of intensive breeding conditions on the evolution of its genome, we analysed structure and copy number of rDNA in 21 cultivars of B. napus, representative of genetic diversity. METHODS: We used next-generation sequencing genomic approaches, Southern blot hybridization, expression analysis and fluorescence in situ hybridization (FISH). Subgenome-specific sequences derived from rDNA intergenic spacers (IGS) were used as probes for identification of loci composition on chromosomes. KEY RESULTS: Most B. napus cultivars (18/21, 86 %) had more A-genome than C-genome rDNA copies. Three cultivars analysed by FISH ('Darmor', 'Yudal' and 'Asparagus kale') harboured the same number (12 per diploid set) of loci. In B. napus 'Darmor', the A-genome-specific rDNA probe hybridized to all 12 rDNA loci (eight on the A-genome and four on the C-genome) while the C-genome-specific probe showed weak signals on the C-genome loci only. Deep sequencing revealed high homogeneity of arrays suggesting that the C-genome genes were largely overwritten by the A-genome variants in B. napus 'Darmor'. In contrast, B. napus 'Yudal' showed a lack of gene conversion evidenced by additive inheritance of progenitor rDNA variants and highly localized hybridization signals of subgenome-specific probes on chromosomes. Brassica napus 'Asparagus kale' showed an intermediate pattern to 'Darmor' and 'Yudal'. At the expression level, most cultivars (95 %) exhibited stable A-genome nucleolar dominance while one cultivar ('Norin 9') showed co-dominance. CONCLUSIONS: The B. napus cultivars differ in the degree and direction of rDNA homogenization. The prevalent direction of gene conversion (towards the A-genome) correlates with the direction of expression dominance indicating that gene activity may be needed for interlocus gene conversion. PMID- 27707749 TI - Sixty seconds on . . . posing. PMID- 27707748 TI - Control of cytokinin and auxin homeostasis in cyanobacteria and algae. AB - BACKGROUND AND AIMS: The metabolism of cytokinins (CKs) and auxins in vascular plants is relatively well understood, but data concerning their metabolic pathways in non-vascular plants are still rather rare. With the aim of filling this gap, 20 representatives of taxonomically major lineages of cyanobacteria and algae from Cyanophyceae, Xanthophyceae, Eustigmatophyceae, Porphyridiophyceae, Chlorophyceae, Ulvophyceae, Trebouxiophyceae, Zygnematophyceae and Klebsormidiophyceae were analysed for endogenous profiles of CKs and auxins and some of them were used for studies of the metabolic fate of exogenously applied radiolabelled CK, [3H]trans-zeatin (transZ) and auxin ([3H]indole-3-acetic acid (IAA)), and the dynamics of endogenous CK and auxin pools during algal growth and cell division. METHODS: Quantification of phytohormone levels was performed by high-performance or ultrahigh-performance liquid chromatography-electrospray tandem mass spectrometry (HPLC-MS/MS, UHPLC-MS/MS). The dynamics of exogenously applied [3H]transZ and [3H]IAA in cell cultures were monitored by HPLC with on line radioactivity detection. KEY RESULTS: The comprehensive screen of selected cyanobacteria and algae for endogenous CKs revealed a predominance of bioactive and phosphate CK forms while O- and N-glucosides evidently did not contribute greatly to the total CK pool. The abundance of cis-zeatin-type CKs and occurrence of CK 2-methylthio derivatives pointed to the tRNA pathway as a substantial source of CKs. The importance of the tRNA biosynthetic pathway was proved by the detection of tRNA-bound CKs during the course of Scenedesmus obliquus growth. Among auxins, free IAA and its oxidation catabolite 2-oxindole-3-acetic acid represented the prevailing endogenous forms. After treatment with [3H]IAA, IAA aspartate and indole-3-acetyl-1-glucosyl ester were detected as major auxin metabolites. Moreover, different dynamics of endogenous CKs and auxin profiles during S. obliquus culture clearly demonstrated diverse roles of both phytohormones in algal growth and cell division. CONCLUSIONS: Our data suggest the existence and functioning of a complex network of metabolic pathways and activity control of CKs and auxins in cyanobacteria and algae that apparently differ from those in vascular plants.

PMID- 27707752 TI - Sound-Triggered Production of Antiaggregation Pheromone Limits Overcrowding of Dendroctonus valens Attacking Pine Trees. AB - For insects that aggregate on host plants, both attraction and antiaggregation among conspecifics can be important mechanisms for overcoming host resistance and avoiding overcrowding, respectively. These mechanisms can involve multiple sensory modalities, such as sound and pheromones. We explored how acoustic and chemical signals are integrated by the bark beetle Dendroctonus valens to limit aggregation in China. In its native North American range, this insect conducts nonlethal attacks on weakened trees at very low densities, but in its introduced zone in China, it uses mixtures of host tree compounds and the pheromone component frontalin to mass attack healthy trees. We found that exo-brevicomin was produced by both female and male D. valens, and that this pheromone functioned as an antiaggregating signal. Moreover, beetles feeding in pairs or in masses were more likely than were beetles feeding alone to produce exo brevicomin, suggesting a potential role of sound by neighboring beetles in stimulating exo-brevicomin production. Sound playback showed that an agreement sound was produced by both sexes when exposed to the aggregation pheromone frontalin and attracts males, and an aggressive sound was produced only by males behaving territorially. These signals triggered the release of exo-brevicomin by both females and males, indicating an interplay of chemical and sonic communication. This study demonstrates that the bark beetle D. valens uses sounds to regulate the production of an antiaggregation pheromone, which may provide new approaches to pest management of this invasive species. PMID- 27707753 TI - MicroRNA-34/449 controls mitotic spindle orientation during mammalian cortex development. AB - Correct orientation of the mitotic spindle determines the plane of cellular cleavage and is crucial for organ development. In the developing cerebral cortex, spindle orientation defects result in severe neurodevelopmental disorders, but the precise mechanisms that control this important event are not fully understood. Here, we use a combination of high-content screening and mouse genetics to identify the miR-34/449 family as key regulators of mitotic spindle orientation in the developing cerebral cortex. By screening through all cortically expressed miRNAs in HeLa cells, we show that several members of the miR-34/449 family control mitotic duration and spindle rotation. Analysis of miR 34/449 knockout (KO) mouse embryos demonstrates significant spindle misorientation phenotypes in cortical progenitors, resulting in an excess of radial glia cells at the expense of intermediate progenitors and a significant delay in neurogenesis. We identify the junction adhesion molecule-A (JAM-A) as a key target for miR-34/449 in the developing cortex that might be responsible for those defects. Our data indicate that miRNA-dependent regulation of mitotic spindle orientation is crucial for cell fate specification during mammalian neurogenesis. PMID- 27707754 TI - Diurnal Rhythm of Cardiac Troponin: Consequences for the Diagnosis of Acute Myocardial Infarction. AB - BACKGROUND: Interpretation of serial high-sensitivity cardiac troponin (hs-cTn) measurements for the diagnosis of acute myocardial infarction (AMI) assumes random fluctuation of hs-cTn around an individual's homeostatic set point. The aim of this study was to challenge this diagnostic concept. METHODS: Study 1 examined the presence of a diurnal hs-cTn rhythm by hourly blood sampling, day and night, in 24 individuals without a recent history of AMI. Study 2 assessed morning vs evening diagnostic accuracy of hs-cTnT and hs-cTnI in a prospective multicenter diagnostic study of 2782 unselected patients, presenting to the emergency department with acute chest pain. RESULTS: In study 1, hs-cTnT, but not hs-cTnI, exhibited a diurnal rhythm, characterized by gradually decreasing concentrations throughout daytime, rising concentrations during nighttime, to peak concentrations in the morning (mean 16.2 ng/L at 8:30 AM and 12.1 ng/L at 7:30 PM). In study 2, the hs-cTnT rhythm was confirmed by higher hs-cTnT concentrations in early-morning presenters compared to evening presenters with an adjudicated diagnosis of noncardiac disease. The diagnostic accuracy [area under the receiver-operation characteristics curve (AUC)] of hs-cTnT at presentation, 1 h, and for the combination of absolute changes with presenting concentration, were very high and comparable among patients presenting early morning as compared to evening (all AUC >0.93). hs-cTnI exhibited no diurnal rhythm with no differences in AUC among early-morning and evening presenters. CONCLUSIONS: Rhythmic diurnal variation of hs-cTnT is a general phenomenon that is not seen with hs-cTnI. While the diurnal hs-cTnT rhythm does not seem to affect the diagnostic accuracy of hs-cTnT for AMI, it should be considered when using hs cTnT for screening purposes. CLINICAL TRIAL REGISTRATION: 1.

PMID- 27707755 TI - Constitutive activation of DIA1 (DIAPH1) via C-terminal truncation causes human sensorineural hearing loss. AB - DIAPH1 encodes human DIA1, a formin protein that elongates unbranched actin. The c.3634+1G>T DIAPH1 mutation causes autosomal dominant nonsyndromic sensorineural hearing loss, DFNA1, characterized by progressive deafness starting in childhood. The mutation occurs near the C-terminus of the diaphanous autoregulatory domain (DAD) of DIA1, which interacts with its N-terminal diaphanous inhibitory domain (DID), and may engender constitutive activation of DIA1. However, the underlying pathogenesis that causes DFNA1 is unclear. We describe a novel patient-derived DIAPH1 mutation (c.3610C>T) in two unrelated families, which results in early termination prior to a basic amino acid motif (RRKR1204-1207) at the DAD C terminus. The mutant DIA1(R1204X) disrupted the autoinhibitory DID-DAD interaction and was constitutively active. This unscheduled activity caused increased rates of directional actin polymerization movement and induced formation of elongated microvilli. Mice expressing FLAG-tagged DIA1(R1204X) experienced progressive deafness and hair cell loss at the basal turn and had various morphological abnormalities in stereocilia (short, fused, elongated, sparse). Thus, the basic region of the DAD mediates DIA1 autoinhibition; disruption of the DID-DAD interaction and consequent activation of DIA1(R1204X) causes DFNA1. PMID- 27707757 TI - A novel fungal killing mechanism of propionic acid. AB - Propionic acid (PPA) is a weak acid that has been used in food products as a preservative because of its inhibitory effect on microorganisms. In the present study, we investigated the PPA fungal killing mechanism, which showed apoptotic features. First, reactive oxygen species (ROS) accumulation and metacaspase activation were detected by 2',7'-dichlorodihydrofluorescein diacetate and CaspACE FITC-VAD-FMK staining, respectively. Increased fluorescence intensities were observed following exposure to PPA, indicating that PPA produced an oxidative environment through the generation of ROS and activation of metacaspase, which can promote apoptosis signaling. We also examined phosphatidylserine externalization (an early apoptosis marker) and DNA and nuclear fragmentation (late apoptosis markers) after exposure to PPA. Based on the results, we determined that PPA exerts its antifungal effect by inducing apoptotic cell death. Moreover, three additional mitochondrial experiments showed mitochondrial membrane depolarization, calcium accumulation and cytochrome c release after cells were exposed to PPA, indicating that the PPA-induced apoptosis pathway is mediated by mitochondria. In conclusion, PPA induces fungal cell death through mitochondria-mediated apoptosis. Results of this study contribute to a deeper understanding of the preservative effects of PPA.

AB - A 22-year-old man had cerebral venous sinus thrombosis and his angiogram incidentally revealed an absent left common carotid artery with bovine origin of the left external carotid artery. There was also an associated low bifurcation of the right common carotid artery and basilar artery fenestration. The absence of a common carotid artery is a very rare angiographic finding, and an association with a bovine origin of the left external carotid artery has not been reported previously in the literature. Here we provide a description of the case along with a review of the literature and embryology. PMID- 27707760 TI - Small-cell neuroendocrine cancer of the prostate: an atypical presentation of a common disease. AB - A 70-year-old man with a history of prostate cancer, previously submitted to surgical castration and trans-urethral resection of the prostate, was admitted to Accident and Emergency department. He had been suffering from osteoarticular and abdominal pain, and recent weight loss. An abdominal and a pelvic CT showed multiple hepatic metastases and a pelvic mass, but his prostate-specific antigen values were low (0.26 n/mL). A biopsy of a hepatic metastasis and of the pelvic mass revealed a small-cell neuroendocrine prostate cancer, a rare and aggressive androgen-independent form of prostate cancer with a poor prognosis. Our purpose was to report a clinical case of a rare and aggressive variant of a common disease. A high index of suspicion is required to make an early diagnosis and to ensure a proper therapeutic approach. PMID- 27707763 TI - Trio of Scientists Wins Lasker Award. AB - Gregg L.

AB - To assess management of non-syndromic dens evaginatus affecting permanent maxillary central incisor, we performed a systematic review and also present a case report. We searched PubMed via MEDLINE and the reference lists of included reports. Eligible studies were any type of clinical studies describing the management of non-syndromic dens evaginatus affecting the crown of a permanent maxillary central incisor. We included 31 studies corresponding to 34 relevant case reports. Therapeutic options were complete reduction of the talon cusp in a single appointment (56%), periodic and gradual reduction of the cusp (26%), abstention (13%) or extraction (5%). We report an 8-year-old girl with unusual two-talon cusp, labial and lingual, on a right maxillary double central incisor. A multidisciplinary approach is key to management of permanent maxillary central incisors affected by coronary anomalies. PMID- 27707766 TI - Disclosing industry ties in articles is not enough.

AB - Shigella spp. represent the second most common etiologic pathogen causing childhood diarrhea in developing countries. There are no licensed Shigella vaccines, and progress for such vaccines has been limited. In this issue of Clinical and Vaccine Immunology, Riddle and colleagues (M. S. Riddle, R. W. Kaminski, C. Di Paolo, C. K. Porter, R. L. Gutierrez, et al., Clin Vaccine Immunol 23:908-917, 2016, http://dx.doi.org/10.1128/CVI.00224-16) report results from a phase I study of a parenterally administered monovalent O-polysaccharide "bioconjugate" directed against Shigella flexneri 2a. Ultimately, the goal is to develop a broad-spectrum Shigella vaccine to address this public health concern. A parenteral Shigella vaccine capable of eliciting protection in children of developing countries would be an important tool to reach this goal. PMID- 27707765 TI - Safety and Immunogenicity of a Parenterally Administered, Structure-Based Rationally Modified Recombinant Staphylococcal Enterotoxin B Protein Vaccine, STEBVax. AB - Staphylococcus aureus produces several enterotoxins and superantigens, exposure to which can elicit profound toxic shock. A recombinant staphylococcal enterotoxin B (rSEB) containing 3 distinct mutations in the major histocompatibility complex class II binding site was combined with an alum adjuvant (Alhydrogel) and used as a potential parenteral vaccine named STEBVax. Consenting healthy adult volunteers (age range, 23 to 38 years) participated in a first-in-human open-label dose escalation study of parenteral doses of STEBVax ranging from 0.01 MUg up to 20 MUg. Safety was assessed by determination of the frequency of adverse events and reactogenicity. Immune responses to the vaccination were determined by measurement of anti-staphylococcal enterotoxin B (anti-SEB) IgG by enzyme-linked immunosorbent assay and a toxin neutralization assay (TNA). Twenty-eight participants were enrolled in 7 dosing cohorts. All doses were well tolerated. The participants exhibited heterogeneous baseline antibody titers. More seroconversions and a faster onset of serum anti-SEB IgG toxin-neutralizing antibodies were observed by TNA with increasing doses of STEBVax. There was a trend for a plateau in antibody responses with doses of STEBVax of between 2.5 and 20 MUg. Among the participants vaccinated with 2.5 MUg to 20 MUg of STEBVax, ~93% seroconverted for SEB toxin-neutralizing antibody. A strong correlation between individual SEB-specific serum IgG antibody titers and the neutralization of gamma interferon production was found in vitro STEBvax appeared to be safe and immunogenic, inducing functional toxin-neutralizing antibodies. These data support its continued clinical development. (This study has been registered at ClinicalTrials.gov under registration no. NCT00974935.). PMID- 27707767 TI - Determinants of hypomagnesemia in patients with type 2 diabetes mellitus. AB - BACKGROUND: Hypomagnesemia (plasma magnesium (Mg2+) concentration <0.7 mmol/L) has been described in patients with type 2 diabetes. Polypharmacy is inevitable when treating a complex disease such as type 2 diabetes and could explain disturbances in the plasma Mg2+ concentration. In this study, we aimed to establish the extent of hypomagnesemia in a cohort of type 2 diabetes patients and to identify the determinants of plasma Mg2+ levels. METHODS: Patient data and samples of 395 type 2 diabetes patients were investigated. Plasma Mg2+ concentrations were measured using a spectrophotometric assay. Using Pearson correlation analyses, variables were correlated to plasma Mg2+ levels. After excluding confounding variables, all parameters correlating (P < 0.1) with plasma Mg2+ were included in a stepwise backward regression model. RESULTS: The mean plasma Mg2+ concentration in this cohort was 0.74 +/- 0.10 mmol/L. In total, 121 patients (30.6%) suffered from hypomagnesemia. Both plasma triglyceride (r = 0.273, P < 0.001) and actual glucose levels (r = -0.231, P < 0.001) negatively correlated with the plasma Mg2+ concentration. Patients using metformin (n = 251, 62%), proton pump inhibitors (n = 179, 45%) or beta-adrenergic receptor agonists (n = 31, 8%) displayed reduced plasma Mg2+ levels. Insulin use (n = 299, 76%) positively correlated with plasma Mg2+ levels. The model predicted (R2) 20% of all variance in the plasma Mg2+ concentration. CONCLUSIONS: Hypomagnesemia is highly prevalent in type 2 diabetes patients. Plasma triglycerides and glucose levels are major determinants of the plasma Mg2+ concentration, whereas only a minor part (<10%) of hypomagnesemia can be explained by drug intake, excluding polypharmacy as a major cause for hypomagnesemia in type 2 diabetes. PMID- 27707768 TI - Marrow adipose tissue spectrum in obesity and type 2 diabetes mellitus. AB - OBJECTIVE: To assess the association of bone mass and marrow adipose tissue (MAT) with other fat depots, insulin resistance, bone remodeling markers, adipokines and glucose control in type 2 diabetes and obesity. DESIGN AND METHODS: The study groups comprised 24 controls (C), 26 obese (O) and 28 type 2 diabetes. Dual energy X-ray absorptiometry was used to determine bone mineral density (BMD). Blood samples were collected for biochemical measurements. 1H Magnetic resonance spectroscopy was used to assess MAT in the L3 vertebra, and abdominal magnetic resonance imaging was used to assess intrahepatic lipids in visceral (VAT) and subcutaneous adipose tissue. Regression analysis models were used to test the association between parameters. RESULTS: At all sites tested, BMD was higher in type 2 diabetes than in O and C subjects. The C group showed lower VAT values than the type 2 diabetes group and lower IHL than the O and type 2 diabetes groups. However, MAT was similar in the 3 groups. Osteocalcin and C-terminal telopeptide of type 1 collagen were lower in type 2 diabetes than those in C and O subjects. Moreover, at all sites, BMD was negatively associated with osteocalcin. No association was observed between MAT and VAT. No relationship was observed among MAT and HOMA-IR, leptin, adiponectin or Pref-1, but MAT was positively associated with glycated hemoglobin. CONCLUSIONS: MAT is not a niche for fat accumulation under conditions of energy surplus and type 2 diabetes, also is not associated with VAT or insulin resistance. MAT is associated with glycated hemoglobin. PMID- 27707770 TI - Milliseconds of Sensory Input Abruptly Modulate the Dynamics of Cortical States for Seconds. AB - Spontaneous internal activity plays a major role in higher brain functions. The question of how it modulates sensory evoked activity and behavior has been explored in anesthetized rodents, cats, monkeys and in behaving human subjects. However, the complementary question of how a brief sensory input modulates the internally generated activity in vivo remains unresolved, and high-resolution mapping of these bidirectional interactions was never performed. Integrating complementary methodologies, at population and single cells levels, we explored this question. Voltage-sensitive dye imaging of population activity in anesthetized rats' somatosensory cortex revealed that spontaneous up-states were largely diminished for ~2 s, even after a single weak whisker deflection. This effect was maximal at the stimulated barrel but spread across several cortical areas. A higher velocity whisker deflection evoked activity at ~15Hz. Two-photon calcium imaging activity and cell-attached recordings confirmed the VSD results and revealed that for several seconds most single cells decreased their firing, but a small number increased firing. Comparing single deflection with long train stimulation, we found a dominant effect of the first population spike. We suggest that, at the onset of a sensory input, some internal messages are silenced to prevent overloading of the processing of relevant incoming sensory information. PMID- 27707769 TI - Distinct Corticocortical Contributions to Human Precision and Power Grip. AB - The corticospinal tract contributes to the control of finger muscles during precision and power grip. The involvement of different sets of cortical interneuronal circuits during these distinct grasping behaviors remains unknown. To examine this question in humans we used noninvasive transcranial magnetic stimulation (TMS) over the hand representation of the primary motor cortex to elicit motor evoked potentials (MEPs) in an intrinsic finger muscle during index finger abduction (control task), precision grip, and power grip. The TMS coil was oriented to induce currents in the brain in the latero-medial (LM), posterior anterior (PA), and anterior-posterior (AP) direction to preferentially activate corticospinal axons directly and early and late synaptic inputs to corticospinal neurons, respectively. We found that AP-LM MEP latency differences were consistently longer during power grip compared with index finger abduction and precision grip, while PA-LM differences remained similar across tasks. Short interval intracortical facilitation, targeting AP but not PA inputs, increased during power grip compared with other tasks. Our novel findings suggest that cortical structures activated by PA and AP stimuli are differentially active during precision and power grip. We propose that a preferential recruitment of late synaptic inputs to corticospinal neurons may be achieved when humans perform a power grip.

AB - Black Drummer (Girella elevata) is a long-lived fish species that experiences considerable recreational fishing pressure, although managers lack a clear understanding of stock structure and dispersal patterns that are essential for the design, implementation, and administration of fisheries stock management. We used 454 sequencing to identify and develop 11 microsatellite primer pairs from 31 G. elevata All loci were found to be polymorphic, with the number of alleles detected ranging from 4 to 8 and observed heterozygosity ranging from 0.19 to 0.87. These markers will be used to assess the genetic diversity and connectivity throughout the range of G. elevata, which can assist in the development of population management strategies. PMID- 27707772 TI - Benchmarking a large regional UK HER2 testing service against current practice guidelines. AB - AIMS: To critically evaluate HER2 testing data for 3500 consecutive cases over 28 months for a single laboratory and review these findings in the light of current UK reporting guidelines. METHODS: We have reviewed all data relating to the HER2 testing service including reagents and analytical machine, HER2 immunohistochemistry (IHC) and fluorescent in situ hybridisation (FISH) scoring profiles. We have examined the place of double counting and rapid screening of FISH and when it is and is not safe to do so. This analysis has been facilitated greatly by the inclusion of custom scripts embedded in a spreadsheet used for recording the data. RESULTS: There were no differences in scoring profiles in relation to testing machine or reagent batch for both HER2 IHC and FISH. There was excellent concordance in scoring by the biomedical scientists and pathologists providing the service. There is a significant difference between the proximity of scores in double-scored cases with HER2 copy number >6.0 compared with those with copy number <6.00. It is safe to single score with rapid screening of HER2 FISH following a first count with a HER2/CEP17 ratio <1.5 and a HER2 copy number <3.5. CONCLUSIONS: Single counting of HER2 FISH supported by a second rapid screen is safe and practicable within strict parameters. Any assessment of proximity of scores in double-scored cases should take into account the HER2 copy number, with greater spreads experienced at higher copy numbers. Centralising HER2 testing in a regional centre allows detailed audit of the entire analytical process. PMID- 27707773 TI - Additive effects of dexamethasone and palmitate on hepatic lipid accumulation and secretion. AB - Synthetic and natural glucocorticoids are able to highly modify liver lipid metabolism, which is possibly associated with nonalcoholic fatty liver disease development. We have assessed the changes in lipid and sphingolipid contents in hepatocytes, lipid composition and saturation status as well as the expression of proteins involved in fatty acid transport after both dexamethasone and palmitate treatments. The experiments were conducted on primary rat hepatocytes, incubated with dexamethasone and/or palmitic acid during short (16 h) and prolonged (40 h) exposure. Intracellular and extracellular lipid and sphingolipid contents were assessed by gas liquid chromatography and high-performance liquid chromatography, respectively. The expression of selected proteins was estimated by Western blotting. Short and prolonged exposure to dexamethasone combined with palmitic acid resulted in increased expression of fatty acid transporters, which was subsequently reflected by excessive intracellular accumulation of triacylglycerols and ceramide. The expression of microsomal transfer protein and cassette transporter was also significantly increased after dexamethasone and palmitate treatment, which was in accordance with elevated extracellular lipid and sphingolipid contents. Our data showed additive effects of dexamethasone and palmitate on protein-dependent fatty acid uptake in primary hepatocytes, resulting in the increased accumulation of triacylglycerols and sphingolipids. Moreover, the combined treatment altered fatty acid composition and diminished triacylglycerols desaturation index. Importantly, we observed that additive effects on both increased microsomal transport protein expression as well as elevated export of triacylglycerols, which may be relevant as a liver protective mechanism.

Agriculture is responsible for a large part of the greenhouse gas (GHG) emissions that have to be urgently reduced in order to protect the environment. At the same time, agriculture has to cope with the challenges of sustainably feeding a growing world population. Reducing the use of the ammonia-nitrate fertilizers that are responsible for a large part of the GHGs released and that have a negative impact on carbon balance is one of the objectives of precision agriculture. One way to reduce N fertilizers without dramatically affecting grain yields is to improve the nitrogen recycling and remobilization performances of plants. Mechanisms involved in nitrogen recycling, such as autophagy, are essential for nutrient remobilization at the whole-plant level and for seed quality. Studies on leaf senescence and nutrient recycling provide new perspectives for improvement. The aim of this review is to give an overview of the mechanisms involved in nitrogen recycling and remobilization during leaf senescence and to present the different approaches undertaken to improve nitrogen remobilization efficiency using both model plants and crop species.

PMID- 27707775 TI - Robust phenotyping strategies for evaluation of stem non-structural carbohydrates (NSC) in rice. AB - Rice plants (Oryza sativa) accumulate excess photoassimilates in the form of non structural carbohydrates (NSCs) in their stems prior to heading that can later be mobilized to supplement photosynthate production during grain-filling. Despite longstanding interest in stem NSC for rice improvement, the dynamics of NSC accumulation, remobilization, and re-accumulation that have genetic potential for optimization have not been systematically investigated. Here we conducted three pilot experiments to lay the groundwork for large-scale diversity studies on rice stem NSC. We assessed the relationship of stem NSC components with 21 agronomic traits in large-scale, tropical yield trials using 33 breeder-nominated lines, established an appropriate experimental design for future genetic studies using a Bayesian framework to sample sub-datasets from highly replicated greenhouse data using 36 genetically diverse genotypes, and used 434 phenotypically divergent rice stem samples to develop two partial least-squares (PLS) models using near infrared (NIR) spectra for accurate, rapid prediction of rice stem starch, sucrose, and total non-structural carbohydrates. We find evidence that stem reserves are most critical for short-duration varieties and suggest that pre heading stem NSC is worthy of further experimentation for breeding early maturing rice.

AB - Important progress has been made in the management of Helicobacter pylori infection and in this fifth edition of the Maastricht Consensus Report, key aspects related to the clinical role of H. pylori were re-evaluated in 2015. In the Maastricht V/Florence Consensus Conference, 43 experts from 24 countries examined new data related to H. pylori in five subdivided workshops: (1) Indications/Associations, (2) Diagnosis, (3) Treatment, (4) Prevention/Public Health, (5) H. pylori and the Gastric Microbiota. The results of the individual workshops were presented to a final consensus voting that included all participants. Recommendations are provided on the basis of the best available evidence and relevance to the management of H. pylori infection in the various clinical scenarios. PMID- 27707778 TI - Urinary Imaging Findings in Young Infants With Bacteremic Urinary Tract Infection. AB - OBJECTIVES: To describe renal ultrasound (RUS) and voiding cystourethrogram (VCUG) findings and determine predictors of abnormal imaging in young infants with bacteremic urinary tract infection (UTI). METHODS: We used retrospective data from a multicenter sample of infants younger than 3 months with bacteremic UTI, defined as the same pathogenic organism in blood and urine. Infants were excluded if they had any major comorbidities, known urologic abnormalities at time of presentation, required intensive unit care, or had no imaging performed. Imaging results as stated in the radiology reports were categorized by a pediatric urologist. RESULTS: Of the 276 infants, 19 were excluded. Of the remaining 257 infants, 254 underwent a RUS and 224 underwent a VCUG. Fifty-five percent had >=1 RUS abnormalities. Thirty-four percent had >=1 VCUG abnormalities, including vesicoureteral reflux (VUR, 27%), duplication (1.3%), and infravesicular abnormality (0.9%). Age <1 month, male sex, and non Escherichia coli organism predicted an abnormal RUS, but only non-E coli organism predicted an abnormal VCUG. Seventeen of 96 infants (17.7%) with a normal RUS had an abnormal VCUG: 15 with VUR (Grade I-III = 13, Grade IV = 2), 2 with elevated postvoid residual, and 1 with infravesical abnormality. CONCLUSIONS: Although RUS and VCUG abnormalities were common in this cohort, the frequency and severity were similar to previous studies of infants with UTIs in general. Our findings do not support special consideration of bacteremia in imaging decisions for otherwise well-appearing young infants with UTI. PMID- 27707779 TI - The hyperexcitability of dentate granule neurons in organotypic hippocampal slice cultures is due to reorganization of synaptic inputs in vitro. AB - Organotypic hippocampal slice cultures (OHSCs) provide the experimental flexibility of cell culture while leaving much of the natural neuronal connectivity intact. Previously, it was shown that the functional and morphological features of CA1 pyramidal neurons in OHSCs resemble, to a surprising extent, those of CA1 neurons in the acute brain slice preparation. However, the extent to which the characteristics of other principle hippocampal neurons change or are preserved in cultured slices remains to be determined. In the present study, I initially sought to understand whether and how the synaptic inputs and morphology of cultured dentate granule neurons (GCs) differ from GCs that have developed in vivo. To this end, I compared GCs in OHSCs and GCs in acute slices at two equivalent developmental time points (P14 vs. DIV7 and P21 vs. DIV21). The findings suggest that there is considerable reorganization of synaptic input to the organotypic GCs, such that these cells are more susceptible to hyperexcitation than GCs in acute slices after 3 weeks. It appears that this hyperexcitability emerges through an increase in the proportion of mature synapses at proximal dendritic sites and is accompanied by an increase in inhibitory neuron activity. These alterations appear to arise in a coordinated manner such that the substantial increase in excitatory synaptic drive received by the DIV21 GCs in OHSCs remains local and is not translated into excessive output possibly leading to damage or major morphological alterations of downstream pyramidal neurons. PMID- 27707780 TI - Typical gray matter axons in mammalian brain fail to conduct action potentials faithfully at fever-like temperatures. AB - We studied the ability of typical unmyelinated cortical axons to conduct action potentials at fever-like temperatures because fever often gives CNS symptoms. We investigated such axons in cerebellar and hippocampal slices from 10 to 25 days old rats at temperatures between 30 and 43 degrees C. By recording with two electrodes along axonal pathways, we confirmed that the axons were able to initiate action potentials, but at temperatures >39 degrees C, the propagation of the action potentials to a more distal recording site was reduced. This temperature-sensitive conduction may be specific for the very thin unmyelinated axons because similar recordings from myelinated CNS axons did not show conduction failures. We found that the conduction fidelity improved with 1 mmol/L TEA in the bath, probably due to block of voltage-sensitive potassium channels responsible for the fast repolarization of action potentials. Furthermore, by recording electrically activated antidromic action potentials from the soma of cerebellar granule cells, we showed that the axons failed less if they were triggered 10-30 msec after another action potential. This was because individual action potentials were followed by a depolarizing after-potential, of constant amplitude and shape, which facilitated conduction of the following action potentials. The temperature-sensitive conduction failures above, but not below, normal body temperature, and the failure-reducing effect of the spike's depolarizing after-potential, are two intrinsic mechanisms in normal gray matter axons that may help us understand how the hyperthermic brain functions.

PMID- 27707782 TI - Functional improvement after successful catheter ablation for long-standing persistent atrial fibrillation. AB - Aims: Identifying patients who benefit from restored sinus rhythm (SR) would optimize the selection of candidates for ablation of long-standing persistent atrial fibrillation (LSPAF). This prospective study sought to identify the hitherto unknown factors associated with global functional improvement after successful radiofrequency catheter ablation of LSPAF. Methods and results: In 171 LSPAF patients (84% of the total consecutive 203 patients) who were examined in SR 12 months after ablation, the individual per cent change from baseline value in maximum oxygen consumption at exercise test (VO2 max), left ventricular ejection fraction (LVEF), N-terminal prohormone of brain natriuretic peptide (NT proBNP), and five-dimensional descriptive system (EQ-5D) of quality-of-life questionnaire were classified in quartiles by 0 (worse) to 3 (best) grades. The individual grades were summed into a composite score (SCORE, 0 ... 12) reflecting global functional improvement. Significant improvement in VO2 max (3.4 +/- 4.7 mL/kg/min), LVEF (7.5 +/- 9.1%), NT-proBNP (-861 +/- 809 pg/mL), and EQ-5D (0.7 +/- 0.12) was observed (all P < 0.0001). On multivariable analysis, younger age (P = 0.001), male gender (P = 0.02), timely post-ablation left atrial appendage (LAA) outflow (P = 0.005) with improvement in outflow velocity (P = 0.0002), and withdrawal of Class I/III antiarrhythmic drugs (P < 0.05) were positively and independently correlated with the SCORE. Conclusions: Younger male patients benefited most from catheter ablation of LSPAF. Delayed or non-improved LAA outflow and inability to discontinue Class I/III antiarrhythmic medication reduced the post-ablation functional improvement. PMID- 27707784 TI - Improved patient selection for cardiac resynchronization therapy by normalization of QRS duration to left ventricular dimension. AB - Aims: This study evaluates the relative importance of two components of QRS prolongation, myocardial conduction velocity and travel distance of the electrical wave front (i.e. path length), for the prediction of acute response to cardiac resynchronization therapy (CRT) in left bundle branch block (LBBB) patients. Methods and results: Thirty-two CRT candidates (ejection fraction <35%, LBBB) underwent cardiac magnetic resonance (CMR) imaging to provide detailed information on left ventricular (LV) dimensions. Left ventricular end-diastolic volume (LVEDV) was used as a primary measure for path length, subsequently QRSd was normalized to LV dimension (i.e. QRSd divided by LVEDV) to adjust for conduction path length. Invasive pressure-volume loop analysis at baseline and during CRT was used to assess acute pump function improvement, expressed as LV stroke work (SW) change. During CRT, SW improved by +38 +/- 46% (P < 0.001). The baseline LVEDV was positively related to QRSd (R = 0.36, P = 0.044). Despite this association, a paradoxical inverse relation was found between LVEDV and SW improvement during CRT (R = -0.40; P = 0.025). Baseline unadjusted QRSd was found to be unrelated to SW changes during CRT (R = 0.16; P = 0.383), whereas normalized QRSd (QRSd/LVEDV) yielded a strong correlation with CRT response (R = 0.49; P = 0.005). Other measures of LV dimension, including LV length, LV diameter, and LV end-systolic volume, showed similar relations with normalized QRSd and SW improvement. Conclusion: Since normalized QRSd reflects myocardial conduction properties, these findings suggest that myocardial conduction velocity rather than increased path length mainly determines response to CRT. Normalizing QRSd to LV dimension might provide a relatively simple method to improve patient selection for CRT. PMID- 27707785 TI - Outcomes of lead extraction without subsequent device reimplantation. AB - Aims: Outcomes among patients who do not receive device reimplantation after cardiovascular implantable electronic device (CIED) extraction have not been well studied. The present study aims to investigate the outcomes of patients without device reimplantation after lead extraction and device removal. Methods and results: We retrospectively searched for consecutive patients who underwent CIED extraction at Mayo Clinic, Rochester, MN and University of California San Diego Medical Center from 2001 through 2012. Among the patients identified, we compared characteristics of those who did and did not have device reimplantation. The Kaplan-Meier survival was analysed. Among 678 patients, 97 patients had their device extracted without reimplantation during 1-year follow-up ('no-reimplant group'). Median age was younger in the no-reimplant group (60.7 vs. 70.6 years; P < 0.001). The reasons for no reimplantation were as follows: no longer meeting criteria for CIED (48%), inappropriate device indication at initial implantation (23%), patient preference (17%), and unresolved device complications (12%). Three major arrhythmias were reported in the no-reimplant group. Overall survival in the no-reimplant group was significantly lower than in the reimplant group (60 vs. 93%; P < 0.001). Ongoing device-related complications [hazard ratio (HR), 3.91; 95% CI, 1.74-8.81; P = 0.001], infection (HR, 3.06; 95% CI, 1.24-7.52; P = 0.02), and concurrent dialysis (HR, 2.74; 95% CI, 1.12-6.71; P = 0.03) were associated with increased mortality. Of 31 deaths in the no-reimplant group, 1 was secondary to cardiac arrhythmia. Conclusion: Fourteen per cent of patients who had device extraction did not undergo reimplantation mainly because they no longer met CIED indications. The high mortality in these patients is related to device complications and comorbid conditions, whereas mortality associated with arrhythmia is rare. PMID- 27707786 TI - Chemo-Genetic Interactions Between Histone Modification and the Antiproliferation Drug AICAR Are Conserved in Yeast and Humans. AB - Identifying synthetic lethal interactions has emerged as a promising new therapeutic approach aimed at targeting cancer cells directly. Here, we used the yeast Saccharomyces cerevisiae as a simple eukaryotic model to screen for mutations resulting in a synthetic lethality with 5-amino-4-imidazole carboxamide ribonucleoside (AICAR) treatment. Indeed, AICAR has been reported to inhibit the proliferation of multiple cancer cell lines. Here, we found that loss of several histone-modifying enzymes, including Bre1 (histone H2B ubiquitination) and Set1 (histone H3 lysine 4 methylation), greatly enhanced AICAR inhibition on growth via the combined effects of both the drug and mutations on G1 cyclins. Our results point to AICAR impacting on Cln3 subcellular localization and at the Cln1 protein level, while the bre1 or set1 deletion affected CLN1 and CLN2 expression. As a consequence, AICAR and bre1/set1 deletions jointly affected all three G1 cyclins (Cln1, Cln2, and Cln3), leading to a condition known to result in synthetic lethality. Significantly, these chemo-genetic synthetic interactions were conserved in human HCT116 cells. Indeed, knock-down of RNF40, ASH2L, and KMT2D/MLL2 induced a highly significant increase in AICAR sensitivity. Given that KMT2D/MLL2 is mutated at high frequency in a variety of cancers, this synthetic lethal interaction has an interesting therapeutic potential. PMID- 27707787 TI - The Identification of a Novel Mutant Allele of topoisomerase II in Caenorhabditis elegans Reveals a Unique Role in Chromosome Segregation During Spermatogenesis. AB - Topoisomerase II alleviates DNA entanglements that are generated during mitotic DNA replication, transcription, and sister chromatid separation. In contrast to mitosis, meiosis has two rounds of chromosome segregation following one round of DNA replication. In meiosis II, sister chromatids segregate from each other, similar to mitosis. Meiosis I, on the other hand, segregates homologs, which requires pairing, synapsis, and recombination. The exact role that topoisomerase II plays during meiosis is unknown. In a screen reexamining Caenorhabditis elegans legacy mutants isolated 30 years ago, we identified a novel allele of the gene encoding topoisomerase II, top-2(it7). In this study, we demonstrate that top-2(it7) males produce dead embryos, even when fertilizing wild-type oocytes. Characterization of early embryonic events indicates that fertilization is successful and sperm components are transmitted to the embryo. However, sperm chromatin is not detected in these fertilized embryos. Examination of top-2(it7) spermatogenic germ lines reveals that the sperm DNA fails to segregate properly during anaphase I of meiosis, resulting in anucleate sperm. top-2(it7) chromosome segregation defects observed during anaphase I are not due to residual entanglements incurred during meiotic DNA replication and are not dependent on SPO-11-induced double-strand DNA breaks. Finally, we show that TOP-2 associates with chromosomes in meiotic prophase and that chromosome association is disrupted in the germ lines of top-2(it7) mutants. PMID- 27707789 TI - A Randomised, Double-blind, Placebo-controlled Trial of Trichuris suis ova in Active Crohn's Disease. AB - Background and Aims: To investigate the efficacy and safety of three different dosages of embryonated, viable eggs of Trichuris suis [TSO] versus placebo for induction of remission in mildly-to-moderately active ileocolonic, uncomplicated Crohn's disease [CD]. Methods: Adults with active CD [n = 252] randomly received six fortnightly doses of 250, 2500, or 7500 TSO/15 ml suspension/day [TSO 250, TSO 2500, TSO 7500], or 15 ml placebo solution/day, in a double-blind fashion, with 4 weeks' follow-up. Primary endpoint was the rate of clinical remission [Crohn's Disease Activity Index [CDAI] < 150] at end of treatment, ie at Week 12 or withdrawal. Secondary endpoints included the course of clinical remission, rate of clinical response, change in CDAI, change in markers of inflammation, mucosal healing, and Physician's Global Assessment. Results: Clinical remission at Week 12 occurred in 38.5%, 35.2%, and 47.2% of TSO 250, TSO 2500, and TSO 7500 patients, respectively, and in 42.9% of placebo recipients. TSO induced a dose dependent immunological response. There was no response regarding laboratory markers of inflammation. Other secondary efficacy variables also showed no advantage of TSO over placebo for treatment of active CD. Administration of TSO did not result in any serious adverse drug reaction. Review of non-serious suspected adverse drug reactions following TSO did not reveal any safety concerns. Conclusions: Administration of 250-7500 TSO fortnightly over 12 weeks was safe and showed a dose-dependent immunological response, but no TSO dose showed a clinically relevant effect over placebo for induction of clinical remission or response in mildly-to-moderately active, ileocolonic CD. PMID- 27707791 TI - Image-based teleconsultation using smartphones or tablets: qualitative assessment of medical experts. AB - BACKGROUND: Mobile health has promising potential in improving healthcare delivery by facilitating access to expert advice. Enabling experts to review images on their smartphone or tablet may save valuable time. This study aims at assessing whether images viewed by medical specialists on handheld devices such as smartphones and tablets are perceived to be of comparable quality as when viewed on a computer screen. METHODS: This was a prospective study comparing the perceived quality of 18 images on three different display devices (smartphone, tablet and computer) by 27 participants (4 burn surgeons and 23 emergency medicine specialists). The images, presented in random order, covered clinical (dermatological conditions, burns, ECGs and X-rays) and non-clinical subjects and their perceived quality was assessed using a 7-point Likert scale. Differences in devices' quality ratings were analysed using linear regression models for clustered data adjusting for image type and participants' characteristics (age, gender and medical specialty). RESULTS: Overall, the images were rated good or very good in most instances and more so for the smartphone (83.1%, mean score 5.7) and tablet (78.2%, mean 5.5) than for a standard computer (70.6%, mean 5.2). Both handheld devices had significantly higher ratings than the computer screen, even after controlling for image type and participants' characteristics. Nearly all experts expressed that they would be comfortable using smartphones (n=25) or tablets (n=26) for image-based teleconsultation. CONCLUSION: This study suggests that handheld devices could be a substitute for computer screens for teleconsultation by physicians working in emergency settings. PMID- 27707788 TI - Positive Selection in Rapidly Evolving Plastid-Nuclear Enzyme Complexes. AB - Rates of sequence evolution in plastid genomes are generally low, but numerous angiosperm lineages exhibit accelerated evolutionary rates in similar subsets of plastid genes. These genes include clpP1 and accD, which encode components of the caseinolytic protease (CLP) and acetyl-coA carboxylase (ACCase) complexes, respectively. Whether these extreme and repeated accelerations in rates of plastid genome evolution result from adaptive change in proteins (i.e., positive selection) or simply a loss of functional constraint (i.e., relaxed purifying selection) is a source of ongoing controversy. To address this, we have taken advantage of the multiple independent accelerations that have occurred within the genus Silene (Caryophyllaceae) by examining phylogenetic and population genetic variation in the nuclear genes that encode subunits of the CLP and ACCase complexes. We found that, in species with accelerated plastid genome evolution, the nuclear-encoded subunits in the CLP and ACCase complexes are also evolving rapidly, especially those involved in direct physical interactions with plastid encoded proteins. A massive excess of nonsynonymous substitutions between species relative to levels of intraspecific polymorphism indicated a history of strong positive selection (particularly in CLP genes). Interestingly, however, some species are likely undergoing loss of the native (heteromeric) plastid ACCase and putative functional replacement by a duplicated cytosolic (homomeric) ACCase. Overall, the patterns of molecular evolution in these plastid-nuclear complexes are unusual for anciently conserved enzymes. They instead resemble cases of antagonistic coevolution between pathogens and host immune genes. We discuss a possible role of plastid-nuclear conflict as a novel cause of accelerated evolution. PMID- 27707792 TI - An ED paradox: patients who arrive by ambulance and then leave without consulting an ED provider. AB - BACKGROUND: Scientists have called for strategies to identify ED patients with unmet needs. We identify the unique profile of ED patients who arrive by ambulance and subsequently leave without consulting a provider (ie, a paradoxical visit, PV). METHODS: Using a retrospective cohort design, administrative data from Winnipeg, Manitoba were interrogated to identify all ED patients 17+ years old as having zero, single or multiple PVs in 2012/2013. Analyses compare the sociodemographic, physical (eg, arthritis), mental (eg, substance abuse) and concurrent healthcare use profile of non-PV, single and multiple PV patients. RESULTS: The study cohort consisted of 122 639 patients with 250 754 ED visits. Across all ED sites, 2.3% of patients (N=2815) made 3387 PVs, comprising 1.4% of all ED visits. Descriptively, more single versus non-PV patients lived in urban core and lowest-income areas, were frequent ED users generally, were substance abusers and had seven plus primary care physician visits. Multiple PV patients had a similar but more extreme profile versus their single PV counterparts (eg, 54.7% of multiple vs 27.4% of single PV patients had substance abuse challenges). From multivariate statistics, single versus non-PV patients are defined uniquely by their frequent ED use, by their substance abuse, as living in a core and low income area, and as having multiple visits with primary care physicians. CONCLUSIONS: PV patients have needs that do not align with the acute model of ED care. These patients may benefit from a more integrated care approach likely involving allied health professionals. PMID- 27707790 TI - Landscape of Genomic Alterations in Pituitary Adenomas. AB - Purpose: Pituitary adenomas are the second most common primary brain tumor, yet their genetic profiles are incompletely understood.Experimental Design: We performed whole-exome sequencing of 42 pituitary macroadenomas and matched normal DNA. These adenomas included hormonally active and inactive tumors, ones with typical or atypical histology, and ones that were primary or recurrent.Results: We identified mutations, insertions/deletions, and copy-number alterations. Nearly one-third of samples (29%) had chromosome arm-level copy-number alterations across large fractions of the genome. Despite such widespread genomic disruption, these tumors had few focal events, which is unusual among highly disrupted cancers. The other 71% of tumors formed a distinct molecular class, with somatic copy number alterations involving less than 6% of the genome. Among the highly disrupted group, 75% were functional adenomas or atypical null-cell adenomas, whereas 87% of the less-disrupted group were nonfunctional adenomas. We confirmed this association between functional subtype and disruption in a validation dataset of 87 pituitary adenomas. Analysis of previously published expression data from an additional 50 adenomas showed that arm-level alterations significantly impacted transcript levels, and that the disrupted samples were characterized by expression changes associated with poor outcome in other cancers. Arm-level losses of chromosomes 1, 2, 11, and 18 were significantly recurrent. No significantly recurrent mutations were identified, suggesting no genes are altered by exonic mutations across large fractions of pituitary macroadenomas.Conclusions: These data indicate that sporadic pituitary adenomas have distinct copy-number profiles that associate with hormonal and histologic subtypes and influence gene expression.

AB - How neural stem cells generate the correct number and type of differentiated neurons in appropriate places remains an important question. Although nervous systems are diverse across phyla, in many taxa the larva forms an anterior concentration of serotonergic neurons, or apical organ. The sea star embryo initially has a pan-neurogenic ectoderm, but the genetic mechanism that directs a subset of these cells to generate serotonergic neurons in a particular location is unresolved. We show that neurogenesis in sea star larvae begins with soxc expressing multipotent progenitors. These give rise to restricted progenitors that express lhx2/9 soxc- and lhx2/9-expressing cells can undergo both asymmetric divisions, allowing for progression towards a particular neural fate, and symmetric proliferative divisions. We show that nested concentric domains of gene expression along the anterior-posterior (AP) axis, which are observed in a great diversity of metazoans, control neurogenesis in the sea star larva by promoting particular division modes and progression towards becoming a neuron. This work explains how spatial patterning in the ectoderm controls progression of neurogenesis in addition to providing spatial cues for neuron location. Modification to the sizes of these AP territories provides a simple mechanism to explain the diversity of neuron number among apical organs. PMID- 27707793 TI - MicroRNA deep sequencing in two adult stem cell populations identifies miR-501 as a novel regulator of myosin heavy chain during muscle regeneration. AB - MicroRNAs (miRNAs) are important regulators of skeletal muscle regeneration, but the underlying mechanisms are still incompletely understood. Here, comparative miRNA sequencing analysis of myogenic progenitor cells (MPs) and non-myogenic fibroblast-adipocyte progenitors (FAPs) during cardiotoxin (CTX)-induced muscle injury uncovered miR-501 as a novel muscle-specific miRNA. miR-501 is an intronic miRNA and its expression levels in MPs correlated with its host gene, chloride channel, voltage-sensitive 5 (Clcn5). Pharmacological inhibition of miR-501 dramatically blunted the induction of embryonic myosin heavy chain (MYH3) and, to a lesser extent, adult myosin isoforms during muscle regeneration, and promoted small-diameter neofibers. An unbiased target identification approach in primary myoblasts validated gigaxonin as a target of miR-501 that mimicked the effect of miR-501 inhibition on MYH3 expression. In the mdx mouse model, which models a pathological disease state, not only was miR-501 induced in regenerating skeletal muscle, but also its serum levels were increased, which correlated with the disease state of the animals. Our results suggest that miR-501 plays a key role in adult muscle regeneration and might serve as a novel serum biomarker for the activation of adult muscle stem cells. PMID- 27707795 TI - A new mode of mitochondrial transport and polarized sorting regulated by Dynein, Milton and Miro. AB - Intrinsic cell microtubule (MT) polarity, together with molecular motors and adaptor proteins, determines mitochondrial polarized targeting and MT-dependent transport. In polarized cells, such as neurons, mitochondrial mobility and transport require the regulation of kinesin and dynein by two adaptor proteins, Milton and Miro. Recently, we found that dynein heavy chain 64C (Dhc64C) is the primary motor protein for both anterograde and retrograde transport of mitochondria in the Drosophila bristle. In this study, we show that a molecular lesion in the Dhc64C allele that reduced bristle mitochondrial velocity generated a variant that acts as a 'slow' dynein in an MT-gliding assay, indicating that dynein directly regulates mitochondrial transport. We also showed that in milton RNAi flies, mitochondrial flux into the bristle shaft, but not velocity, was significantly reduced. Surprisingly, mitochondria retrograde flux, but not net velocity, was significantly decreased in miro-RNAi flies. We thus reveal a new mode of mitochondrial sorting in polarized cell growth, whereby bi-directional mitochondrial transport undertaken exclusively by dynein is regulated by Milton in the anterograde direction and by a Miro-dependent switch to the retrograde direction. PMID- 27707797 TI - Antagonism between beta-catenin and Gata.a sequentially segregates the germ layers of ascidian embryos. AB - Many animal embryos use nuclear beta-catenin (nbeta-catenin) during the segregation of endomesoderm (or endoderm) from ectoderm. This mechanism is thus likely to be evolutionarily ancient. In the ascidian embryo, nbeta-catenin reiteratively drives binary fate decisions between ectoderm and endomesoderm at the 16-cell stage, and then between endoderm and margin (mesoderm and caudal neural) at the 32-cell stage. At the 16-cell stage, nbeta-catenin activates endomesoderm genes in the vegetal hemisphere. At the same time, nbeta-catenin suppresses the DNA-binding activity of a maternal transcription factor, Gata.a, through a physical interaction, and Gata.a thereby activates its target genes only in the ectodermal lineage. In the present study, we found that this antagonism between nbeta-catenin and Gata.a also operates during the binary fate switch at the 32-cell stage. Namely, in marginal cells where nbeta-catenin is absent, Gata.a directly activates its target, Zic-r.b (ZicL), to specify the marginal cell lineages. Thus, the antagonistic action between nbeta-catenin and Gata.a is involved in two consecutive stages of germ layer segregation in ascidian embryos. PMID- 27707796 TI - iDamIDseq and iDEAR: an improved method and computational pipeline to profile chromatin-binding proteins. AB - DNA adenine methyltransferase identification (DamID) has emerged as an alternative method to profile protein-DNA interactions; however, critical issues limit its widespread applicability. Here, we present iDamIDseq, a protocol that improves specificity and sensitivity by inverting the steps DpnI-DpnII and adding steps that involve a phosphatase and exonuclease. To determine genome-wide protein-DNA interactions efficiently, we present the analysis tool iDEAR (iDamIDseq Enrichment Analysis with R). The combination of DamID and iDEAR permits the establishment of consistent profiles for transcription factors, even in transient assays, as we exemplify using the small teleost medaka (Oryzias latipes). We report that the bacterial Dam-coding sequence induces aberrant splicing when it is used with different promoters to drive tissue-specific expression. Here, we present an optimization of the sequence to avoid this problem. This and our other improvements will allow researchers to use DamID effectively in any organism, in a general or targeted manner.

PMID- 27707798 TI - The GDNF-GFRalpha1 complex promotes the development of hippocampal dendritic arbors and spines via NCAM. AB - The formation of synaptic connections during nervous system development requires the precise control of dendrite growth and synapse formation. Although glial cell line-derived neurotrophic factor (GDNF) and its receptor GFRalpha1 are expressed in the forebrain, the role of this system in the hippocampus remains unclear. Here, we investigated the consequences of GFRalpha1 deficiency for the development of hippocampal connections. Analysis of conditional Gfra1 knockout mice shows a reduction in dendritic length and complexity, as well as a decrease in postsynaptic density specializations and in the synaptic localization of postsynaptic proteins in hippocampal neurons. Gain- and loss-of-function assays demonstrate that the GDNF-GFRalpha1 complex promotes dendritic growth and postsynaptic differentiation in cultured hippocampal neurons. Finally, in vitro assays revealed that GDNF-GFRalpha1-induced dendrite growth and spine formation are mediated by NCAM signaling. Taken together, our results indicate that the GDNF-GFRalpha1 complex is essential for proper hippocampal circuit development.

AB - RATIONALE: Immune cells play an important role during the generation and resolution of thrombosis. T cells are powerful regulators of immune and nonimmune cell function, however, their role in sterile inflammation in venous thrombosis has not been systematically examined. OBJECTIVE: This study investigated the recruitment, activation, and inflammatory activity of T cells in deep vein thrombosis and its consequences for venous thrombus resolution. METHODS AND RESULTS: CD4+ and CD8+ T cells infiltrate the thrombus and vein wall rapidly on deep vein thrombosis induction and remain in the tissue throughout the thrombus resolution. In the vein wall, recruited T cells largely consist of effector memory T (TEM) cells. Using T-cell receptor transgenic reporter mice, we demonstrate that deep vein thrombosis-recruited TEM receive an immediate antigen independent activation and produce IFN-gamma (interferon) in situ. Mapping inflammatory conditions in the thrombotic vein, we identify a set of deep vein thrombosis upregulated cytokines and chemokines that synergize to induce antigen independent IFN-gamma production in CD4+ and CD8+ TEM cells. Reducing the number of TEM cells through a depletion recovery procedure, we show that intravenous TEM activation determines neutrophil and monocyte recruitment and delays thrombus neovascularization and resolution. Examining T-cell recruitment in human venous stasis, we show that superficial varicose veins preferentially contain activated memory T cells. CONCLUSIONS: TEM orchestrate the inflammatory response in venous thrombosis affecting thrombus resolution.

AB - Background: Dysphagia is a known risk factor for malnutrition and pneumonia. Although sarcopenia is hypothesized to cause dysphagia, its causality remains unclear. Thus, this study aimed to investigate causality and the risk factors for sarcopenic dysphagia. Methods: We enrolled 95 hospitalized patients aged 65 years or older who had restricted oral intake without dysphagia. The skeletal muscle index and Functional Oral Intake Scale were used to evaluate muscle mass and swallowing ability, respectively. Nutritional status, assessed by body mass index, the Mini Nutritional Assessment-Short Form, and energy intake; activity of daily living, assessed by the Barthel Index; hand-grip strength; duration of oral intake restriction; and cognitive status were measured. Dysphagia (Functional Oral Intake Scale <= 5) was determined after 2 months. Results: The participants' mean age was 83.2 +/- 8.0 years; 63% were women. Of the surviving 82 patients, 63 (77%) had sarcopenia and 21 (26%) developed dysphagia, all of whom had sarcopenia (p = .002). Most variables were risk factors for dysphagia on univariate analysis. Decreased skeletal muscle index (odds ratio [OR] 24.0, 95% confidence interval [CI] 3.6-159.0, p = .001), Barthel Index (OR 12.9, 95% CI 2.1-78.4, p = .005), and body mass index (OR 11.4, 95% CI 1.8-70.5, p = .009) were independent predictors of dysphagia in the multivariate analysis. Conclusion: This study provides evidence for sarcopenic dysphagia and its risk factors. Preventive and therapeutic interventions require further study. PMID- 27707801 TI - Mitochondrial Carriers Link the Catabolism of Hydroxyaromatic Compounds to the Central Metabolism in Candida parapsilosis. AB - The pathogenic yeast Candida parapsilosis metabolizes hydroxyderivatives of benzene and benzoic acid to compounds channeled into central metabolism, including the mitochondrially localized tricarboxylic acid cycle, via the 3 oxoadipate and gentisate pathways. The orchestration of both catabolic pathways with mitochondrial metabolism as well as their evolutionary origin is not fully understood. Our results show that the enzymes involved in these two pathways operate in the cytoplasm with the exception of the mitochondrially targeted 3 oxoadipate CoA-transferase (Osc1p) and 3-oxoadipyl-CoA thiolase (Oct1p) catalyzing the last two reactions of the 3-oxoadipate pathway. The cellular localization of the enzymes indicates that degradation of hydroxyaromatic compounds requires a shuttling of intermediates, cofactors, and products of the corresponding biochemical reactions between cytosol and mitochondria. Indeed, we found that yeast cells assimilating hydroxybenzoates increase the expression of genes SFC1, LEU5, YHM2, and MPC1 coding for succinate/fumarate carrier, coenzyme A carrier, oxoglutarate/citrate carrier, and the subunit of pyruvate carrier, respectively. A phylogenetic analysis uncovered distinct evolutionary trajectories for sparsely distributed gene clusters coding for enzymes of both pathways. Whereas the 3-oxoadipate pathway appears to have evolved by vertical descent combined with multiple losses, the gentisate pathway shows a striking pattern suggestive of horizontal gene transfer to the evolutionarily distant Mucorales. PMID- 27707802 TI - Evolutionary Genomics of Peach and Almond Domestication. AB - The domesticated almond [Prunus dulcis (L.) Batsch] and peach [P. persica (Mill.) D. A. Webb] originated on opposite sides of Asia and were independently domesticated ~5000 yr ago. While interfertile, they possess alternate mating systems and differ in a number of morphological and physiological traits. Here, we evaluated patterns of genome-wide diversity in both almond and peach to better understand the impacts of mating system, adaptation, and domestication on the evolution of these taxa. Almond has around seven times the genetic diversity of peach, and high genome-wide [Formula: see text] values support their status as separate species. We estimated a divergence time of ~8 MYA (million years ago), coinciding with an active period of uplift in the northeast Tibetan Plateau and subsequent Asian climate change. We see no evidence of a bottleneck during domestication of either species, but identify a number of regions showing signatures of selection during domestication and a significant overlap in candidate regions between peach and almond. While we expected gene expression in fruit to overlap with candidate selected regions, instead we find enrichment for loci highly differentiated between the species, consistent with recent fossil evidence suggesting fruit divergence long preceded domestication. Taken together, this study tells us how closely related tree species evolve and are domesticated, the impact of these events on their genomes, and the utility of genomic information for long-lived species. Further exploration of this data will contribute to the genetic knowledge of these species and provide information regarding targets of selection for breeding application, and further the understanding of evolution in these species. PMID- 27707803 TI - A novel TRAPPC11 mutation in two Turkish families associated with cerebral atrophy, global retardation, scoliosis, achalasia and alacrima. AB - BACKGROUND: Triple A syndrome (MIM #231550) is associated with mutations in the AAAS gene. However, about 30% of patients with triple A syndrome symptoms but an unresolved diagnosis do not harbour mutations in AAAS. OBJECTIVE: Search for novel genetic defects in families with a triple A-like phenotype in whom AAAS mutations are not detected. METHODS: Genome-wide linkage analysis, whole-exome sequencing and functional analyses were used to discover and verify a novel genetic defect in two families with achalasia, alacrima, myopathy and further symptoms. Effect and pathogenicity of the mutation were verified by cell biological studies. RESULTS: We identified a homozygous splice mutation in TRAPPC11 (c.1893+3A>G, [NM_021942.5], g.4:184,607,904A>G [hg19]) in four patients from two unrelated families leading to incomplete exon skipping and reduction in full-length mRNA levels. TRAPPC11 encodes for trafficking protein particle complex subunit 11 (TRAPPC11), a protein of the transport protein particle (TRAPP) complex. Western blot analysis revealed a dramatic decrease in full length TRAPPC11 protein levels and hypoglycosylation of LAMP1. Trafficking experiments in patient fibroblasts revealed a delayed arrival of marker proteins in the Golgi and a delay in their release from the Golgi to the plasma membrane. Mutations in TRAPPC11 have previously been described to cause limb-girdle muscular dystrophy type 2S (MIM #615356). Indeed, muscle histology of our patients also revealed mild dystrophic changes. Immunohistochemically, beta sarcoglycan was absent from focal patches. CONCLUSIONS: The identified novel TRAPPC11 mutation represents an expansion of the myopathy phenotype described before and is characterised particularly by achalasia, alacrima, neurological and muscular phenotypes. PMID- 27707805 TI - Telomerase RNA Component Genetic Variants Interact With the Mediterranean Diet Modifying the Inflammatory Status and its Relationship With Aging: CORDIOPREV Study. AB - Background: Leukocyte telomere length (LTL) attrition has been associated with age-related diseases. Telomerase RNA Component (TERC) genetic variants have been associated with LTL; whereas fatty acids (FAs) can interact with genetic factors and influence in aging. We explore whether variability at the TERC gene locus interacts with FA profile and two healthy diets (low-fat diet vs Mediterranean diet [MedDiet]) modulating LTL, glucose metabolism, and inflammation status in coronary heart disease (CHD) patients. Methods: Inflammation status (high sensitivity C-reactive protein [hsCRP], glucose metabolism-glucose, insulin, and glycated hemoglobin [HbA1c], and homeostasis model assessment of insulin resistance [HOMA-IR]), LTL, FAs, and single nucleotide polymorphisms (SNPs) of the TERC gene (rs12696304, rs16847897, and rs3772190) were determined in 1,002 patients from the CORDIOPREV study (NCT00924937). Results: We report an interaction of the TERC rs12696304 SNP with monounsaturated fatty acid (MUFA) affecting LTL (p interaction = .01) and hsCRP (p interaction = .03). Among individuals with MUFA levels above the median, CC individuals showed higher LTL and lower hsCRP than G-allele carriers. Moreover, MedDiet interacted with TERC rs12696304 SNP (p interaction = .03). Specifically, CC individuals displayed a greater decrease in hsCRP than G-allele carriers. These results were not adjusted for multiple statistical testing and p less than .05 was considered significant. Conclusions: Our findings suggest that the TERC rs12696304 SNP interacts with MUFA improving inflammation status and telomere attrition related with CHD. Moreover, the MedDiet intervention improves the inflammatory profile in CC individuals compared with the G-allele carriers. These interactions could provide a right strategy for personalized nutrition in CHD patients. PMID- 27707807 TI - Immunogenicity of Varicella Vaccine and Immunologic Predictors of Response in a Cohort of Elderly Nursing Home Residents. AB - BACKGROUND: Little is known about the immunogenicity of live-attenuated Oka/Merck varicella zoster virus (VZV)-containing vaccine (hereafter, "varicella vaccine") in frail nursing homes residents nor about immune phenotypes associated with a response. METHODS: A cohort of 190 frail nursing home residents aged 80 102 years and a cohort of 50 community-dwelling seniors aged 60-75 years (a comparison group) received varicella vaccine. Interferon gamma (IFN-gamma) enzyme linked immunospot assays were performed before and 6 weeks after vaccination. Cellular markers of immunosenescence were measured in the nursing home elderly. RESULTS: The average number of IFN-gamma spot-forming cells at baseline was significantly lower in the elderly nursing home residents than in the community dwelling seniors. However, following vaccination, the VZV immune response increased in both cohorts, and no difference was noted in the fold difference of the response between the 2 cohorts. Upon further examination of the elderly nursing home residents, we found that higher frequencies of regulatory T cells and cytomegalovirus-specific CD4+ T cells correlated negatively with the magnitude of VZV-specific responses. CONCLUSIONS: The Oka/Merck varicella vaccine induces VZV immunity in elderly nursing home residents that is similar to that produced in community-dwelling seniors. CLINICAL TRIALS REGISTRATION: NCT01328548. PMID- 27707806 TI - Replication of Genome-Wide Association Study Findings of Longevity in White, African American, and Hispanic Women: The Women's Health Initiative. AB - Background: No study has evaluated whether genetic factors are associated with longevity in African Americans or Hispanics, and it is unclear whether genetic factors are associated with healthy aging. Methods: In this prospective study, we determined whether 14 genetic variants previously associated with longevity in genome-wide association studies were associated with survival to ages 85 and 90 in 11,053 postmenopausal white, African American, and Hispanic women from the Women's Health Initiative. The associations of these variants with healthy aging, defined as survival to age 85 without chronic diseases or disability, were also determined. Results: Among white women, three single nucleotide polymorphisms (SNPs) (rs2075650 [TOMM40], rs4420638 [APOC1], and rs429358 [APOE]) were significantly associated with survival to 90 years after correction for multiple testing (p < .001); rs4420638 and rs429358 were also significantly associated with healthy aging (p = .02). In African American women, no SNP was associated with longevity. In Hispanic women, 7 SNPs in linkage disequilibrium with a novel SNP, rs2149954, recently identified as being associated with increased longevity in a European population, were significantly associated with decreased survival to age 85 for carriers of the T versus C allele (p = .04). The association with decreased longevity was explained by higher risk of coronary heart disease in carriers of the T allele. There were no associations between FOXO3A SNPs and longevity in the analyses. In a meta-analysis, rs2075650 and rs429358 were significantly associated with longevity. Conclusions: Future studies are needed to identify novel loci associated with longevity in African American and Hispanic women to determine biologic pathways regulating life span in these groups. PMID- 27707808 TI - Genomic Characteristics Behind the Spread of Bacteremic Group A Streptococcus Type emm89 in Finland, 2004-2014. AB - BACKGROUND: Many countries worldwide have reported increasing numbers of emm89 group A Streptococcus (GAS) infections during last decade. Pathogen genetic factors linked to this increase need assessment. METHODS: We investigated epidemiological characteristics of emm89 GAS bacteremic infections, including 7 day and 30-day case-fatality rates, in Finland during 2004-2014 and linked them to whole-genome sequencing data obtained from corresponding strains. The Fisher exact test and exact logistic regression were used to compare differences between bacteremic infections due to emm89 GAS belonging to different genetic clades and subclades. RESULTS: Out of 1928 cases of GAS bacteremic infection, 278 were caused by emm89 GAS. We identified 2 genetically distinct clades, arbitrarily designated clade 2 and clade 3. Both clades were present during 2004-2008, but clade 3 increased rapidly from 2009 onward. Six subclades (designated subclades A F) were identified within clade 3, based on phylogenetic core genome analysis. The case-fatality rate differed significantly between subclades (P < .05), with subclade D having the highest 30-day estimated case-fatality rate (19% vs 3% 14%). CONCLUSIONS: A new emm89 clone, clade 3, emerged in 2009 and spread rapidly in Finland. Patients infected with certain subclades of clade 3 were significantly more likely to die. A specific polymerase chain reaction assay was developed to follow the spread of subclade D in 2015. PMID- 27707809 TI - Whisker row deprivation affects the flow of sensory information through rat barrel cortex. AB - : Whisker trimming causes substantial reorganization of neuronal response properties in barrel cortex. However, little is known about experience-dependent rerouting of sensory processing following sensory deprivation. To address this, we performed in vivo intracellular recordings from layers 2/3 (L2/3), layer 4 (L4), layer 5 regular-spiking (L5RS), and L5 intrinsically bursting (L5IB) neurons and measured their multiwhisker receptive field at the level of spiking activity, membrane potential, and synaptic conductance before and after sensory deprivation. We used Chernoff information to quantify the "sensory information" contained in the firing patterns of cells in response to spared and deprived whisker stimulation. In the control condition, information for flanking-row and same-row whiskers decreased in the order L4, L2/3, L5IB, L5RS. However, after whisker-row deprivation, spared flanking-row whisker information was reordered to L4, L5RS, L5IB, L2/3. Sensory information from the trimmed whiskers was reduced and delayed in L2/3 and L5IB neurons, whereas sensory information from spared whiskers was increased and advanced in L4 and L5RS neurons. Sensory information from spared whiskers was increased in L5IB neurons without a latency change. L5RS cells exhibited the largest changes in sensory information content through an atypical plasticity combining a significant decrease in spontaneous activity and an increase in a short-latency excitatory conductance. NEW & NOTEWORTHY: Sensory cortical plasticity is usually quantified by changes in evoked firing rate. In this study we quantified plasticity by changes in sensory detection performance using Chernoff information and receiver operating characteristic analysis. We found that whisker deprivation causes a change in information flow within the cortical layers and that layer 5 regular-spiking cells, despite showing only a small potentiation of short-latency input, show the greatest increase in information content for the spared input partly by decreasing their spontaneous activity. PMID- 27707810 TI - GSG1L regulates the strength of AMPA receptor-mediated synaptic transmission but not AMPA receptor kinetics in hippocampal dentate granule neurons. AB - : GSG1L is an AMPA receptor (AMPAR) auxiliary subunit that regulates AMPAR trafficking and function in hippocampal CA1 pyramidal neurons. However, its physiological roles in other types of neurons remain to be characterized. Here, we investigated the role of GSG1L in hippocampal dentate granule cells and found that GSG1L is important for the regulation of synaptic strength but is not critical for the modulation of AMPAR deactivation and desensitization kinetics. These data demonstrate a neuronal type-specific role of GSG1L and suggest that physiological function of AMPAR auxiliary subunits may vary in different types of neurons. NEW & NOTEWORTHY: GSG1L is a newly identified AMPA receptor (AMPAR) auxiliary subunit and plays a unique role in the regulation of AMPAR trafficking and function in hippocampal CA1 pyramidal neurons. However, its role in the regulation of AMPARs in hippocampal dentate granule cells remains to be characterized. The current work reveals that GSG1L regulates strength of AMPAR mediated synaptic transmission but not the receptor kinetic properties in hippocampal dentate granule neurons. PMID- 27707811 TI - Specific connectivity between photoreceptors and horizontal cells in the zebrafish retina. AB - The functional and morphological connectivity between various horizontal cell (HC) types (H1, H2, H3, and H4) and photoreceptors was studied in zebrafish retina. Since HCs are strongly coupled by gap junctions and feedback from HCs to photoreceptors depends strongly on connexin (Cx) hemichannels, we characterized the various HC Cxs (Cx52.6, Cx52.7, Cx52.9, and Cx55.5) in Xenopus oocytes. All Cxs formed hemichannels that were conducting at physiological membrane potentials. The Cx hemichannels differed in kinetic properties and voltage dependence, allowing for specific tuning of the coupling of HCs and the feedback signal from HCs to cones. The morphological connectivity between HC layers and cones was determined next. We used zebrafish expressing green fluorescent protein under the control of Cx promoters. We found that all HCs showed Cx55.5 promoter activity. Cx52.7 promoter activity was exclusively present in H4 cells, while Cx52.9 promoter activity occurred only in H1 cells. Cx52.6 promoter activity was present in H4 cells and in the ventral quadrant of the retina also in H1 cells. Finally, we determined the spectral sensitivities of the HC layers. Three response types were found. Monophasic responses were generated by HCs that contacted all cones (H1 cells), biphasic responses were generated by HCs that contacted M, S, and UV cones (H2 cells), and triphasic responses were generated by HCs that contacted either S and UV cones (H3 cells) or rods and UV cones (H4 cells). Electron microscopy confirms that H4 cells innervate cones. This indicates that rod-driven HCs process spectral information during photopic and luminance information during scotopic conditions. PMID- 27707812 TI - Spontaneous activity is correlated with coding density in primary auditory cortex. AB - Sensory neurons across sensory modalities and specific processing areas have diverse levels of spontaneous firing rates (SFRs) in the absence of sensory stimuli. However, the functional significance of this spontaneous activity is not well-understood. Previous studies in the auditory system have demonstrated that different levels of spontaneous activity are correlated with a variety of physiological and anatomic properties, suggesting that neurons with differing SFRs make unique contributions to the encoding of auditory stimuli. Additionally, altered SFRs are a correlate of tinnitus, arising in several auditory areas after exposure to ototoxic substances and noise trauma. In this study, we recorded single-unit activity from primary auditory cortex of awake marmoset monkeys while delivering wide-band random-spectrum stimuli and white Gaussian noise (WGN) to examine any divergences in stimulus encoding properties across SFR classes. We found that higher levels of spontaneous activity were associated with both higher levels of activation relative to suppression across a variety of wide-band stimuli and higher driven rates in response to WGN. Moreover, response latencies to WGN were negatively correlated with the level of activation in response to both stimulus types. These findings are consistent with a novel view of the role spontaneous spiking may play during normal stimulus processing in primary auditory cortex and how it may malfunction in cases of tinnitus. PMID- 27707814 TI - Acetaminophen study yields new insights into neurobiological underpinnings of empathy. AB - Empathy is a cornerstone of social behavior, impairments of which are characteristic of neuropsychiatric disorders such as autism and psychopathy. According to the "shared representations" theory, empathy relies on neural processes similar to those underpinning the first-hand experience of a given emotion. A recent study by Mischkowski, Crocker, and Way (Soc Cogn Affect Neurosci 11: 1345-1353, 2016) provides novel insights into neurobiological underpinnings of empathy by demonstrating that acetaminophen, a widely used painkiller, reduces empathy for other's physical and social pain. PMID- 27707813 TI - Neural tracking of attended versus ignored speech is differentially affected by hearing loss. AB - : Hearing loss manifests as a reduced ability to understand speech, particularly in multitalker situations. In these situations, younger normal-hearing listeners' brains are known to track attended speech through phase-locking of neural activity to the slow-varying envelope of the speech. This study investigates how hearing loss, compensated by hearing aids, affects the neural tracking of the speech-onset envelope in elderly participants with varying degree of hearing loss (n = 27, 62-86 yr; hearing thresholds 11-73 dB hearing level). In an active listening task, a to-be-attended audiobook (signal) was presented either in quiet or against a competing to-be-ignored audiobook (noise) presented at three individualized signal-to-noise ratios (SNRs). The neural tracking of the to-be attended and to-be-ignored speech was quantified through the cross-correlation of the electroencephalogram (EEG) and the temporal envelope of speech. We primarily investigated the effects of hearing loss and SNR on the neural envelope tracking. First, we found that elderly hearing-impaired listeners' neural responses reliably track the envelope of to-be-attended speech more than to-be-ignored speech. Second, hearing loss relates to the neural tracking of to-be-ignored speech, resulting in a weaker differential neural tracking of to-be-attended vs. to-be-ignored speech in listeners with worse hearing. Third, neural tracking of to-be-attended speech increased with decreasing background noise. Critically, the beneficial effect of reduced noise on neural speech tracking decreased with stronger hearing loss. In sum, our results show that a common sensorineural processing deficit, i.e., hearing loss, interacts with central attention mechanisms and reduces the differential tracking of attended and ignored speech. NEW & NOTEWORTHY: The present study investigates the effect of hearing loss in older listeners on the neural tracking of competing speech. Interestingly, we observed that whereas internal degradation (hearing loss) relates to the neural tracking of ignored speech, external sound degradation (ratio between attended and ignored speech; signal-to-noise ratio) relates to tracking of attended speech. This provides the first evidence for hearing loss affecting the ability to neurally track speech. PMID- 27707815 TI - Secondary generalization of focal-onset seizures: examining the relationship between seizure propagation and epilepsy surgery outcome. AB - Surgical intervention often fails to achieve seizure-free results in patients with intractable epilepsy. Identifying features of the epileptic brain that dispose certain patients to unfavorable outcomes is critical for improving surgical candidacy assessments. Recent research by Martinet, Ahmad, Lepage, Cash, and Kramer (J Neurosci 35: 9477-9490, 2015) suggests that pathways of secondary seizure generalization distinguish patients with favorable (i.e., seizure free) vs. unfavorable (i.e., seizure persistent) surgical outcomes, lending insights into the network mechanisms of epilepsy surgery failure. PMID- 27707816 TI - Dose-dependent effects of siRNA-mediated inhibition of SCAP on PCSK9, LDLR, and plasma lipids in mouse and rhesus monkey. AB - SREBP cleavage-activating protein (SCAP) is a key protein in the regulation of lipid metabolism and a potential target for treatment of dyslipidemia. SCAP is required for activation of the transcription factors SREBP-1 and -2. SREBPs regulate the expression of genes involved in fatty acid and cholesterol biosynthesis, and LDL-C clearance through the regulation of LDL receptor (LDLR) and PCSK9 expression. To further test the potential of SCAP as a novel target for treatment of dyslipidemia, we used siRNAs to inhibit hepatic SCAP expression and assess the effect on PCSK9, LDLR, and lipids in mice and rhesus monkeys. In mice, robust liver Scap mRNA knockdown (KD) was achieved, accompanied by dose-dependent reduction in SREBP-regulated gene expression, de novo lipogenesis, and plasma PCSK9 and lipids. In rhesus monkeys, over 90% SCAP mRNA KD was achieved resulting in approximately 75, 50, and 50% reduction of plasma PCSK9, TG, and LDL-C, respectively. Inhibition of SCAP function was demonstrated by reduced expression of SREBP-regulated genes and de novo lipogenesis. In conclusion, siRNA-mediated inhibition of SCAP resulted in a significant reduction in circulating PCSK9 and LDL-C in rodent and primate models supporting SCAP as a novel target for the treatment of dyslipidemia. PMID- 27707817 TI - Effect of evolocumab on cholesterol synthesis and absorption. AB - The effects of cholesterol-lowering drugs, including those that reduce cholesterol synthesis (statins) and those that reduce cholesterol absorption (ezetimibe), on cholesterol absorption and synthesis are well understood. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are a novel class of cholesterol-lowering drugs that robustly reduce LDL-cholesterol (LDL-C), but little is known about their effects on cholesterol absorption and synthesis. We evaluated how treatment with evolocumab, a fully human monoclonal IgG2 antibody to PCSK9, affects markers of cholesterol synthesis and absorption by measuring these markers in patients from an evolocumab clinical trial. At 2 weeks, changes in beta-sitosterol/total cholesterol (TC) from baseline were 4% for placebo, 10% for evolocumab 140 mg (nonsignificant vs. placebo), and 26% for evolocumab 420 mg (P < 0.001 vs. placebo). Changes in campesterol/TC at week 2, relative to baseline between placebo and evolocumab, were all nonsignificant. Evolocumab had a modest effect on markers of cholesterol synthesis. At 2 weeks, changes in desmosterol/TC were 1% for placebo, 7% for evolocumab 140 mg (nonsignificant vs. placebo), and 15% for evolocumab 420 mg (P < 0.01 vs. placebo). Changes from baseline in lathosterol/TC at week 2 between placebo and evolocumab were nonsignificant. These results suggest that evolocumab has a modest effect on cholesterol synthesis and absorption despite significant LDL-C lowering. PMID- 27707818 TI - Monoacylglycerol-enriched oil increases EPA/DHA delivery to circulatory system in humans with induced lipid malabsorption conditions. AB - It was hypothesized that under induced lipid malabsorption/maldigestion conditions, an enriched sn-1(3)-monoacylglycerol (MAG) oil may be a better carrier for n-3 long-chain PUFAs (LC-PUFAs) compared with triacylglycerol (TAG) from fish oil. This monocentric double blinded clinical trial examined the accretion of EPA (500 mg/day) and DHA (300 mg/day) when consumed as TAG or MAG, into the erythrocytes, plasma, and chylomicrons of 45 obese (BMI >=30 kg/m2 and <=40 kg/m2) volunteers who were and were not administered Orlistat, an inhibitor of pancreatic lipases. Intake of MAG-enriched oil resulted in higher accretion of LC-PUFAs than with TAG, the concentrations of EPA and DHA in erythrocytes being, respectively, 72 and 24% higher at 21 days (P < 0.001). In addition, MAG increased the plasma concentration of EPA by 56% (P < 0.001) as compared with TAG. In chylomicrons, MAG intake yielded higher levels of EPA with the area under the curve (0-10 h) of EPA being 55% greater (P = 0.012). In conclusion, in obese human subjects with Orlistat-induced lipid maldigestion/malabsorption conditions, LC-PUFA MAG oil increased LC-PUFA levels in erythrocytes, plasma, and chylomicrons to a greater extent than TAG. These results indicate that MAG oil might require minimal enzymatic digestion prior to intestinal uptake and transfer across the epithelial barrier. PMID- 27707819 TI - Toward automated assessment of health Web page quality using the DISCERN instrument. AB - Background: As the Internet becomes the number one destination for obtaining health-related information, there is an increasing need to identify health Web pages that convey an accurate and current view of medical knowledge. In response, the research community has created multicriteria instruments for reliably assessing online medical information quality. One such instrument is DISCERN, which measures health Web page quality by assessing an array of features. In order to scale up use of the instrument, there is interest in automating the quality evaluation process by building machine learning (ML)-based DISCERN Web page classifiers. Objective: The paper addresses 2 key issues that are essential before constructing automated DISCERN classifiers: (1) generation of a robust DISCERN training corpus useful for training classification algorithms, and (2) assessment of the usefulness of the current DISCERN scoring schema as a metric for evaluating the performance of these algorithms. Methods: Using DISCERN, 272 Web pages discussing treatment options in breast cancer, arthritis, and depression were evaluated and rated by trained coders. First, different consensus models were compared to obtain a robust aggregated rating among the coders, suitable for a DISCERN ML training corpus. Second, a new DISCERN scoring criterion was proposed (features-based score) as an ML performance metric that is more reflective of the score distribution across different DISCERN quality criteria. Results: First, we found that a probabilistic consensus model applied to the DISCERN instrument was robust against noise (random ratings) and superior to other approaches for building a training corpus. Second, we found that the established DISCERN scoring schema (overall score) is ill-suited to measure ML performance for automated classifiers. Conclusion: Use of a probabilistic consensus model is advantageous for building a training corpus for the DISCERN instrument, and use of a features-based score is an appropriate ML metric for automated DISCERN classifiers. Availability: The code for the probabilistic consensus model is available at https://bitbucket.org/A_2/em_dawid/ . PMID- 27707820 TI - Understanding vasopressor intervention and weaning: risk prediction in a public heterogeneous clinical time series database. AB - Background: The widespread adoption of electronic health records allows us to ask evidence-based questions about the need for and benefits of specific clinical interventions in critical-care settings across large populations. Objective: We investigated the prediction of vasopressor administration and weaning in the intensive care unit. Vasopressors are commonly used to control hypotension, and changes in timing and dosage can have a large impact on patient outcomes. Materials and Methods: We considered a cohort of 15 695 intensive care unit patients without orders for reduced care who were alive 30 days post-discharge. A switching-state autoregressive model (SSAM) was trained to predict the multidimensional physiological time series of patients before, during, and after vasopressor administration. The latent states from the SSAM were used as predictors of vasopressor administration and weaning. Results: The unsupervised SSAM features were able to predict patient vasopressor administration and successful patient weaning. Features derived from the SSAM achieved areas under the receiver operating curve of 0.92, 0.88, and 0.71 for predicting ungapped vasopressor administration, gapped vasopressor administration, and vasopressor weaning, respectively. We also demonstrated many cases where our model predicted weaning well in advance of a successful wean. Conclusion: Models that used SSAM features increased performance on both predictive tasks. These improvements may reflect an underlying, and ultimately predictive, latent state detectable from the physiological time series. PMID- 27707821 TI - Human resource information systems in health care: a systematic evidence review. AB - Objective: This systematic review aimed to: (1) determine the prevalence and scope of existing research on human resource information systems (HRIS) in health organizations; (2) analyze, classify, and synthesize evidence on the processes and impacts of HRIS development, implementation, and adoption; and (3) generate recommendations for HRIS research, practice, and policy, with reference to the needs of different stakeholders. Methods: A structured search strategy was used to interrogate 10 electronic databases indexing research from the health, social, management, technology, and interdisciplinary sciences, alongside gray literature sources and reference lists of qualifying studies. There were no restrictions on language or publication year. Two reviewers screened publications, extracted data, and coded findings according to the innovation stages covered in the studies. The Critical Appraisal Skills Program checklist was adopted to assess study quality. The process of study selection was charted using a Preferred Items for Systematic Reviews and Meta-Analysis (PRISMA) diagram. Results: Of the 6824 publications identified by the search strategy, 68, covering 42 studies, were included for final analysis. Research on HRIS in health was interdisciplinary, often atheoretical, conducted primarily in the hospital sector of high-income economies, and largely focused uncritically on use and realized benefits. Discussion and Conclusions: While studies of HRIS in health exist, the overall lack of evaluative research raises unanswered questions about their capacity to improve quality and efficiency and enable learning health systems, as well as how sociotechnical complexity influences implementation and effectiveness. We offer this analysis to decision makers and managers considering or currently implementing an HRIS, and make recommendations for further research.

PMID- 27707822 TI - Using social media to monitor mental health discussions - evidence from Twitter. AB - Objectives: Given the public health importance of communicating about mental illness and the growing use of social media to convey information, our goal was to develop an empirical model to identify periods of heightened interest in mental health topics on Twitter. Materials and Methods: We collected data on 176 million tweets from 2011 to 2014 with content related to depression or suicide. Using an autoregressive integrated moving average (ARIMA) data analysis, we identified deviations from predicted trends in communication about depression and suicide. Results: Two types of heightened Twitter activity regarding depression or suicide were identified in 2014: expected increases in response to planned behavioral health events, and unexpected increases in response to unanticipated events. Tweet volume following expected increases went back to the predicted level more rapidly than the volume following unexpected events. Discussion: Although ARIMA models have been used extensively in other fields, they have not been used widely in public health. Our findings indicate that our ARIMA model is valid for identifying periods of heightened activity on Twitter related to behavioral health. The model offers an objective and empirically based measure to identify periods of greater interest for timing the dissemination of credible information related to mental health. Conclusion: Spikes in tweet volume following a behavioral health event often last for less than 2 days. Individuals and organizations that want to disseminate behavioral health messages on Twitter in response to heightened periods of interest need to take this limited time frame into account. PMID- 27707823 TI - Toxoplasma gondii seroprevalence in the Portuguese population: comparison of three cross-sectional studies spanning three decades. AB - BACKGROUND: Toxoplasma gondii is an obligate intracellular protozoan infecting up to one-third of the world's population, constituting a life threat if transmitted from mother to child during pregnancy. In Portugal, there is a lack of knowledge of the current epidemiological situation, as the unique toxoplasmosis National Serological Survey was performed in 1979/1980. METHODS: We studied the seroprevalence trends in the Portuguese general population over the past 3 decades, by assessing chronological spread cross-sectional studies, with special focus on women of childbearing age, by age group, region and gender. RESULTS: The T. gondii overall seroprevalence decreased from 47% in 1979/1980 to 22% (95% CI 20% to 24%) in 2013. Generally, we observed that the prevalence of T. gondii IgG increased significantly with age and it decreased over time, both in the general population and in the childbearing women (18% prevalence in 2013). CONCLUSIONS: The scenario observed for the latter indicates that more than 80% of childbearing women are susceptible to primary infection yielding a risk of congenital toxoplasmosis and respective sequelae. Since there is no vaccine to prevent human toxoplasmosis, the improvement of primary prevention constitutes a major tool to avoid infection in such susceptible groups. PMID- 27707825 TI - Patients' estimations of the importance of preventive health services: a nationwide, population-based cross-sectional study in Portugal. AB - OBJECTIVES: To determine, in the context of primary care preventive health services, the level of importance that Portuguese patients attribute to different preventive activities. DESIGN: Cross-sectional study. SETTING: Primary Healthcare, Portugal. PARTICIPANTS: 1000 Portuguese adults selected by a stratified cluster sampling design were invited to participate in a computer assisted telephone survey. Persons with a cognitive or physical disability that hampered the ability to complete a telephone interview and being a nursing home resident or resident in any other type of collective dwelling were excluded. OUTCOMES: Mean level of importance assigned to 20 different medical preventive activities, using a scale of 1-10, with 1 corresponding to 'no importance for you and your health' and 10 indicating 'very important'. RESULTS: The mean level of importance assigned to medical preventive activity was 7.70 (95% CI 7.60 to 7.80). Routine blood and urine tests were considered the most important, with an estimated mean of 9.15 (95% CI 9.07 to 9.24), followed by female-specific interventions (Pap smear, mammography and gynaecological and breast ultrasounds), with mean importance ranging from 8.45 (95% CI 8.23 to 8.63) for mammography to 8.56 (95% CI 8.36 to 8.76) for Pap smear. Advice regarding alcohol consumption (6.18; 95% CI 5.96 to 6.39) and tobacco consumption (5.99; 95% CI 5.75 to 6.23) were considered much less important. CONCLUSIONS: Our results reveal that Portuguese patients overestimate the importance of preventive medical activities, tend to give more importance to diagnostic and laboratory tests than to lifestyle measures, do not discriminate tests that are important and evidence-based, and seem not be aware of the individualisation of risk. Family physicians should be aware of these optimistic expectations, because these can influence the doctor patient relationship when discussing these interventions and incorporating personalised risk. PMID- 27707826 TI - Symptoms in patients with takotsubo syndrome: a qualitative interview study. AB - OBJECTIVE: The aim of the study was to investigate the meaning of narrated symptoms in connection to takotsubo syndrome. DESIGN, METHOD, PARTICIPANTS AND SETTING: Qualitative study consisting of 25 interviews, 23 women and 2 men aged 39-84 and living in Region Vastra Gotaland, Sweden. The transcribed text was analysed with phenomenological hermeneutics. RESULTS: The interviewees reported a large number of symptoms before, during and after the acute onset of takotsubo syndrome, including pain, affected breathing, lassitude, malaise and nausea. Several of these have not been reported previously. Symptoms before the acute onset were, even if they had been prominent, ignored by the interviewees for various reasons. During the acute phase, the symptoms could no longer be ignored and the interviewees sought healthcare. The remaining residual symptom after discharge from hospital caused a great deal of worry because the interviewees feared that they would be permanent and they felt they could not live this way. On the whole, becoming ill and having a large number of symptoms greatly impacted the lives of the interviewees and made them re-evaluate how they had been living. Furthermore, they reported feeling alone and lost regarding their symptom burden, especially in relation to their residual symptoms, which affected their health and ability to return to daily life. CONCLUSIONS: Acute symptoms, and symptoms before and after the acute ones, are a major part of the illness experience for patients with takotsubo syndrome and affect their health and well-being. Assessment of symptoms should be an integrated part of care to promote health. One way of achieving this is through the patients' own narratives of their experiences, which are an important component in person-centred care. PMID- 27707824 TI - Experiences of long-term life-limiting conditions among patients and carers: what can we learn from a meta-review of systematic reviews of qualitative studies of chronic heart failure, chronic obstructive pulmonary disease and chronic kidney disease? AB - OBJECTIVES: To summarise and synthesise published qualitative studies to characterise factors that shape patient and caregiver experiences of chronic heart failure (CHF), chronic obstructive pulmonary disease (COPD) and chronic kidney disease (CKD). DESIGN: Meta-review of qualitative systematic reviews and metasyntheses. Papers analysed using content analysis. DATA SOURCES: CINAHL, EMBASE, MEDLINE, PsychINFO, Scopus and Web of Science were searched from January 2000 to April 2015. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Systematic reviews and qualitative metasyntheses where the participants were patients, caregivers and which described experiences of care for CHF, COPD and CKD in primary and secondary care who were aged >=18 years. RESULTS: Searches identified 5420 articles, 53 of which met inclusion criteria. Reviews showed that patients' and caregivers' help seeking and decision-making were shaped by their degree of structural advantage (socioeconomic status, spatial location, health service quality); their degree of interactional advantage (cognitive advantage, affective state and interaction quality) and their degree of structural resilience (adaptation to adversity, competence in managing care and caregiver response to demands). CONCLUSIONS: To the best of our knowledge, this is the first synthesis of qualitative systematic reviews in the field. An important outcome of this overview is an emphasis on what patients and caregivers value and on attributes of healthcare systems, relationships and practices that affect the distressing effects and consequences of pathophysiological deterioration in CHF, COPD and CKD. Interventions that seek to empower individual patients may have limited effectiveness for those who are most affected by the combined weight of structural, relational and practical disadvantage identified in this overview. We identify potential targets for interventions that could address these disadvantages. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42014014547. PMID- 27707827 TI - IMproved exercise tolerance in patients with PReserved Ejection fraction by Spironolactone on myocardial fibrosiS in Atrial Fibrillation rationale and design of the IMPRESS-AF randomised controlled trial. AB - INTRODUCTION: Patients with atrial fibrillation frequently suffer from heart failure with preserved ejection fraction. At present there is no proven therapy to improve physical capacity and quality of life in participants with permanent atrial fibrillation with preserved left ventricular contractility. OBJECTIVE: The single-centre IMproved exercise tolerance In heart failure With PReserved Ejection fraction by Spironolactone On myocardial fibrosiS In Atrial Fibrillation (IMPRESS-AF) trial aims to establish whether treatment with spironolactone as compared with placebo improves exercise tolerance (cardiopulmonary exercise testing), quality of life and diastolic function in patients with permanent atrial fibrillation. METHODS AND ANALYSIS: A total of 250 patients have been randomised in this double-blinded trial for 2-year treatment with 25 mg daily dose of spironolactone or matched placebo. Included participants are 50 years old or older, have permanent atrial fibrillation and ejection fraction >55%. Exclusion criteria include contraindications to spironolactone, poorly controlled hypertension and presence of severe comorbidities with life expectancy <2 years. The primary outcome is improvement in exercise tolerance at 2 years and key secondary outcomes include quality of life (assessed using the EuroQol EQ-5D-5L (EQ-5D) and Minnesota Living with Heart Failure (MLWHF) questionnaires), diastolic function and all-cause hospitalisation. ETHICS AND DISSEMINATION: The study has been approved by the National Research and Ethics Committee West Midlands-Coventry and Warwickshire (REC reference number 14/WM/1211). The results of the trial will be published in an international peer-reviewed journal. TRIAL REGISTRATION NUMBERS: EudraCT2014-003702-33; NCT02673463; Pre-results. PMID- 27707828 TI - Fracture in the Elderly Multidisciplinary Rehabilitation (FEMuR): a phase II randomised feasibility study of a multidisciplinary rehabilitation package following hip fracture. AB - OBJECTIVE: To conduct a rigorous feasibility study for a future definitive parallel-group randomised controlled trial (RCT) and economic evaluation of an enhanced rehabilitation package for hip fracture. SETTING: Recruitment from 3 acute hospitals in North Wales. Intervention delivery in the community. PARTICIPANTS: Older adults (aged >=65) who received surgical treatment for hip fracture, lived independently prior to fracture, had mental capacity (assessed by clinical team) and received rehabilitation in the North Wales area. INTERVENTION: Remote randomisation to usual care (control) or usual care+enhanced rehabilitation package (intervention), including six additional home-based physiotherapy sessions delivered by a physiotherapist or technical instructor, novel information workbook and goal-setting diary. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary: Barthel Activities of Daily Living (BADL). Secondary measures included Nottingham Extended Activities of Daily Living scale (NEADL), EQ-5D, ICECAP capability, a suite of self-efficacy, psychosocial and service-use measures and costs. Outcome measures were assessed at baseline and 3-month follow up by blinded researchers. RESULTS: 62 participants were recruited, 61 randomised (control 32; intervention 29) and 49 (79%) completed 3-month follow-up. Minimal differences occurred between the 2 groups for most outcomes, including BADL (adjusted mean difference 0.5). The intervention group showed a medium-sized improvement in the NEADL relative to the control group, with an adjusted mean difference between groups of 3.0 (Cohen's d 0.63), and a trend for greater improvement in self-efficacy and mental health, but with small effect sizes. The mean cost of delivering the intervention was L231 per patient. There was a small relative improvement in quality-adjusted life year in the intervention group. No serious adverse events relating to the intervention were reported. CONCLUSIONS: The trial methods were feasible in terms of eligibility, recruitment and retention. The effectiveness and cost-effectiveness of the rehabilitation package should be tested in a phase III RCT. TRIAL REGISTRATION NUMBER: ISRCTN22464643; Results. PMID- 27707830 TI - Glycaemic control and antidiabetic treatment trends in primary care centres in patients with type 2 diabetes mellitus during 2007-2013 in Catalonia: a population-based study. AB - OBJECTIVES: To assess trends in prescribing practices of antidiabetic agents and glycaemic control in patients with type 2 diabetes mellitus (T2DM). DESIGN: Cross sectional analysis using yearly clinical data and antidiabetic treatments prescribed obtained from an electronic population database. SETTING: Primary healthcare centres, including the entire population attended by the Institut Catala de la Salut in Catalonia, Spain, from 2007 to 2013. PARTICIPANTS: Patients aged 31-90 years with a diagnosis of T2DM. RESULTS: The number of registered patients with T2DM in the database was 257 072 in 2007, increasing up to 343 969 in 2013. The proportion of patients not pharmacologically treated decreased by 9.7% (95% CI -9.48% to -9.92%), while there was an increase in the percentage of patients on monotherapy (4.4% increase; 95% CI 4.16% to 4.64%), combination therapy (2.8% increase; 95% CI 2.58% to 3.02%), and insulin alone or in combination (increasing 2.5%; 95% CI 2.2% to 2.8%). The use of metformin and dipeptidyl peptidase-IV inhibitors increased gradually, while sulfonylureas, glitazones and alpha-glucosidase inhibitors decreased. The use of glinides remained stable, and the use of glucagon-like peptide-1 receptor agonists was still marginal. Regarding glycaemic control, there were no relevant differences across years: mean glycated haemoglobin (HbA1c) value was around 7.2%; the percentage of patients reaching an HbA1c<=7% target ranged between 52.2% and 55.6%; and those attaining their individualised target from 72.8% to 75.7%. CONCLUSIONS: Although the proportion of patients under pharmacological treatment increased substantially over time and there was an increase in the use of combination therapies, there have not been relevant changes in glycaemic control during the 2007-2013 period in Catalonia. PMID- 27707829 TI - Gamification for health promotion: systematic review of behaviour change techniques in smartphone apps. AB - OBJECTIVE: Smartphone games that aim to alter health behaviours are common, but there is uncertainty about how to achieve this. We systematically reviewed health apps containing gaming elements analysing their embedded behaviour change techniques. METHODS: Two trained researchers independently coded apps for behaviour change techniques using a standard taxonomy. We explored associations with user ratings and price. DATA SOURCES: We screened the National Health Service (NHS) Health Apps Library and all top-rated medical, health and wellness and health and fitness apps (defined by Apple and Google Play stores based on revenue and downloads). We included free and paid English language apps using 'gamification' (rewards, prizes, avatars, badges, leaderboards, competitions, levelling-up or health-related challenges). We excluded apps targeting health professionals. RESULTS: 64 of 1680 (4%) health apps included gamification and met inclusion criteria; only 3 of these were in the NHS Library. Behaviour change categories used were: feedback and monitoring (n=60, 94% of apps), reward and threat (n=52, 81%), and goals and planning (n=52, 81%). Individual techniques were: self-monitoring of behaviour (n=55, 86%), non-specific reward (n=49, 82%), social support unspecified (n=48, 75%), non-specific incentive (n=49, 82%) and focus on past success (n=47, 73%). Median number of techniques per app was 14 (range: 5-22). Common combinations were: goal setting, self-monitoring, non specific reward and non-specific incentive (n=35, 55%); goal setting, self monitoring and focus on past success (n=33, 52%). There was no correlation between number of techniques and user ratings (p=0.07; rs=0.23) or price (p=0.45; rs=0.10). CONCLUSIONS: Few health apps currently employ gamification and there is a wide variation in the use of behaviour change techniques, which may limit potential to improve health outcomes. We found no correlation between user rating (a possible proxy for health benefits) and game content or price. Further research is required to evaluate effective behaviour change techniques and to assess clinical outcomes. TRIAL REGISTRATION NUMBER: CRD42015029841. PMID- 27707831 TI - Comparing physical assessment with administrative data for detecting pressure ulcers in a large Canadian academic health sciences centre. AB - OBJECTIVE: This study aimed to compare classification of pressure ulcers from administrative data with a gold standard assessment, specifically; pressure ulcers confirmed by an independent physical assessment performed by trained nurse surveyors. SETTING: A retrospective analysis of pooled cross-sectional samples of inpatients assessed across 3 consecutive prevalence surveys in a large academic health sciences centre between 2012 and 2013. PARTICIPANTS: There were 2001 patients for whom physical and chart assessments were completed, and for whom a discharge abstract was also available at the time of analysis. The cohort's mean age was 65 years and 55% were women. RESULTS: Based on the physical assessment findings, 14.6% of patients (n=292) had at least 1 pressure ulcer, with a total of 345 pressure ulcers documented among these patients: (stage I=162; stage II=120; stage III=22; stage IV=22 and unstageable=19). Based on coded information, 78 (3.9%) of patients had a pressure ulcer. Of patients with a pressure ulcer determined by the physical assessment, only 21% also had a pressure ulcer captured in the administrative data. Furthermore, only 6% of the patients with a hospital-acquired pressure ulcer, stage II or greater determined by the physical assessment were coded in the Discharge Abstract Database (DAD). CONCLUSIONS: The results of this study demonstrate that coding in the DAD may under-report and fail to accurately reflect the true burden of pressure ulcers in hospitalised patients. This may occur because the presence of pressure ulcers is currently documented in the health record by nurses and not by physicians, yet the administrative data recorded in the DAD only includes physician documented pressure ulcers. We recommend enhancements to the coding methods to monitor and report on pressure ulcers. PMID- 27707832 TI - Readmissions and mortality in delirious versus non-delirious octogenarian patients after aortic valve therapy: a prospective cohort study. AB - OBJECTIVES: To determine whether postoperative delirium predicts first-time readmissions and mortality in octogenarian patients within 180 days after aortic valve therapy with surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI), and to determine the most common diagnoses at readmission. DESIGN: Prospective cohort study of patients undergoing elective SAVR or TAVI. SETTING: Tertiary university hospital that performs all SAVRs and TAVIs in Western Norway. PARTICIPANTS: Patients 80+ years scheduled for SAVR or TAVI and willing to participate in the study were eligible. Those unable to speak Norwegian were excluded. Overall, 143 patients were included, and data from 136 are presented. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was a composite variable of time from discharge to first all-cause readmission or death. Secondary outcomes were all-cause first readmission alone and mortality within 180 days after discharge, and the primary diagnosis at discharge from first-time readmission. Delirium was assessed with the confusion assessment method. First-time readmissions, diagnoses and mortality were identified in hospital information registries. RESULTS: Delirium was identified in 56% of patients. The effect of delirium on readmissions and mortality was greatest during the first 2 months after discharge (adjusted HR 2.9 (95% CI 1.5 to 5.7)). Of 30 first-time readmissions occurring within 30 days, 24 (80%) were patients who experienced delirium. 1 patient (non-delirium group) died within 30 days after therapy. Delirious patients comprised 35 (64%) of 55 first-time readmissions occurring within 180 days. Circulatory system diseases and injuries were common causes of first-time readmissions within 180 days in delirious patients. 8 patients died 180 days after the procedure; 6 (75%) of them experienced delirium. CONCLUSIONS: Delirium in octogenarians after aortic valve therapy might be a serious risk factor for postoperative morbidity and mortality. Cardiovascular disorders and injuries were associated with first-time readmissions in these patients. PMID- 27707833 TI - Development and validation of a screening tool for the identification of inappropriate transthoracic echocardiograms. AB - OBJECTIVE: We sought whether simple clinical markers could be used in a questionnaire for recognition of inappropriate (or rarely appropriate, RA) tests at point-of-service. Most applications of appropriateness criteria (AC) for transthoracic echocardiogram (TTE) have been at the point of order, but a simple means of identifying RA tests in an audit process would be of value. DESIGN, SETTING AND PARTICIPANTS: The study was performed in 2 major hospitals in Tasmania. 2 reviewers created a questionnaire based on 4 questions most commonly associated with RA (suspected endocarditis with no positive blood cultures or new murmur, lack of cardiovascular symptoms or no change in clinical status or cardiac examination, routine surveillance and previous TTE within a year) in a derivation cohort of 814 patients. This was prospectively applied to 499 TTEs to calculate sensitivity and specificity for prediction of RA, and validated in the external group (n=880). RESULTS: Of 499 prospective TTEs, the questionnaire selected 18% requests as being potentially RA. As 7.4% were actually RA (kappa 89%), the sensitivity and specificity of the questionnaire were 84% and 87%, respectively. In the external validation cohort, the model found 11% requests needed to be screened for appropriateness with a sensitivity and specificity of 80% and 95%. CONCLUSIONS: A questionnaire based on 4 questions detects a high proportion of RA TTE, and could be used for audit. PMID- 27707834 TI - Cohort feasibility study of an intermittent pneumatic compression device within a below-knee cast for the prevention of venous thromboembolism. AB - OBJECTIVES: To determine the likely enrolment rate of eligible participants into a randomised controlled trial (RCT) in which a within-cast intermittent pneumatic compression device using Jet Impulse Technology (IPC/JIT) is 1 of 3 possible interventions in a RCT for the prevention of venous thromboembolism (VTE) in the clinical setting of isolated lower limb cast immobilisation. DESIGN: A prospective, open-label feasibility study of the IPC/JIT device placed within a lower limb cast. SETTING: Wellington Regional Hospital Fracture Clinic. PARTICIPANTS: Individuals aged 18-70 who presented with a lower limb injury requiring a minimum of 4 weeks below-knee cast immobilisation. INTERVENTION: Placement of an IPC/JIT device within lower limb cast. OUTCOME MEASURES: The main outcome measure was the proportion of eligible participants who participated in the feasibility study. Secondary outcome measures included adherence to device usage throughout the study, ease of application of the device and adverse events potentially associated with its use. RESULTS: The proportion of potentially eligible participants for the IPC/JIT device was only 7/142 (5%), 95% CI 2 to 9.9. Devices were used for a mean (range) of 4.1 (1.9 to 10.2) hours per day and none of 7 participants had adequate adherence to the device. 3 of the 7 participants suffered an adverse event, including 1 deep vein thrombosis, 2 dorsal foot ulcer and 1 skin maceration. CONCLUSIONS: A within-cast IPC/JIT device is unlikely to be a feasible randomisation arm for a RCT assessing possible interventions for the reduction of VTE risk in the clinical setting of lower limb injury requiring below knee cast immobilisation for a minimum of 4 weeks. TRIAL REGISTRATION NUMBER: ANZCTR 12615000192583. PMID- 27707835 TI - Examination of psychosocial predictors of Chinese hospital pharmacists' intention to provide clinical pharmacy services using the theory of planned behaviour: a cross-sectional questionnaire study. AB - OBJECTIVES: Main study aim was as follows: (1) to explore the usefulness of the theory of planned behaviour (TPB) model in predicting Chinese hospital pharmacists' intention to provide clinical pharmacy services (CPSs), including auxiliary CPSs and core CPSs; (2) to identify the main factors affecting the Chinese hospital pharmacists' intention to provide core CPSs based on TPB quantitatively. DESIGN: Cross-sectional questionnaire study. SETTING: The study was conducted in 22 general hospitals in seven cities located in the eastern and western part of China. PARTICIPANTS: 416 hospital pharmacists (292 (70.2%) female) entered and completed the study. PRIMARY AND SECONDARY OUTCOME MEASURES: Quantitative responses with hospital pharmacists' intention, attitude, subjective norms (SNs) and perceived behavioural control (PBC) over provision of CPSs and their past behaviour (PB)-related CPSs. RESULTS: The structural equation model analysis found that attitude (p=0.0079, beta=0.12), SN (p=0.038, beta=0.10) and the pharmacists' intention to provide auxiliary CPSs (p=0.0001, beta=0.63) significantly predicted of their intention to provide core CPSs, accounting for 54.0% of its variance. Attitude (p=0.0001, beta=0.35), PBC (p=0.0182, beta=0.12) and PB (p=0.0009, beta=0.15) are significant predictors of pharmacists' intention, accounting for 21% of the variance in pharmacists' intention to provide auxiliary CPSs. CONCLUSIONS: The TPB with the addition of PB is a useful framework for predicting pharmacists' intention to provide CPSs in Chinese hospital care context. Strategies to improve hospital pharmacists' intention to provide CPSs should focus on helping the individuals related medical care see the value of CPSs, altering their perception of social pressure towards core CPSs and the removal of obstacles that impede the translation of intentions into behaviour.

PMID- 27707836 TI - Strength Training for Adolescents with cerebral palsy (STAR): study protocol of a randomised controlled trial to determine the feasibility, acceptability and efficacy of resistance training for adolescents with cerebral palsy. AB - INTRODUCTION: Gait is inefficient in children with cerebral palsy, particularly as they transition to adolescence. Gait inefficiency may be associated with declines in gross motor function and participation among adolescents with cerebral palsy. Resistance training may improve gait efficiency through a number of biomechanical and neural mechanisms. The aim of the Strength Training for Adolescents with cerebral palsy (STAR) trial is to evaluate the effect of resistance training on gait efficiency, activity and participation in adolescents with cerebral palsy. We also aim to determine the biomechanical and neural adaptations that occur following resistance training and evaluate the feasibility and acceptability of such an intervention for adolescents with cerebral palsy. METHODS AND ANALYSIS: 60 adolescents (Gross Motor Function Classification System level I-III) will be randomised to a 10-week resistance training group or a usual care control group according to a computer-generated random schedule. The primary outcome is gait efficiency. Secondary outcomes are habitual physical activity, participation, muscle-tendon mechanics and gross motor function. General linear models will be used to evaluate differences in continuous data between the resistance training and usual care groups at 10 and 22 weeks, respectively. A process evaluation will be conducted alongside the intervention. Fidelity of the resistance training programme to trial protocol will be quantified by observations of exercise sessions. Semistructured interviews will be conducted with participants and physiotherapists following the resistance training programme to determine feasibility and acceptability of the programme. ETHICS AND DISSEMINATION: This trial has ethical approval from Brunel University London's Department of Clinical Sciences' Research Ethics Committee and the National Research Ethics Service (NRES) Committee London-Surrey Borders. The results of the trial will be submitted for publication in academic journals, presented at conferences and distributed to adolescents, families and healthcare professionals through the media with the assistance of the STAR advisory group.

AB - Background: Previously we identified a DNA damage response-deficient (DDRD) molecular subtype within breast cancer. A 44-gene assay identifying this subtype was validated as predicting benefit from DNA-damaging chemotherapy. This subtype was defined by interferon signaling. In this study, we address the mechanism of this immune response and its possible clinical significance. Methods: We used immunohistochemistry (IHC) to characterize immune infiltration in 184 breast cancer samples, of which 65 were within the DDRD subtype. Isogenic cell lines, which represent DDRD-positive and -negative, were used to study the effects of chemokine release on peripheral blood mononuclear cell (PBMC) migration and the mechanism of immune signaling activation. Finally, we studied the association between the DDRD subtype and expression of the immune-checkpoint protein PD-L1 as detected by IHC. All statistical tests were two-sided. Results: We found that DDRD breast tumors were associated with CD4+ and CD8+ lymphocytic infiltration (Fisher's exact test P < .001) and that DDRD cells expressed the chemokines CXCL10 and CCL5 3.5- to 11.9-fold more than DNA damage response-proficient cells (P < .01). Conditioned medium from DDRD cells statistically significantly attracted PBMCs when compared with medium from DNA damage response-proficient cells (P < .05), and this was dependent on CXCL10 and CCL5. DDRD cells demonstrated increased cytosolic DNA and constitutive activation of the viral response cGAS/STING/TBK1/IRF3 pathway. Importantly, this pathway was activated in a cell cycle-specific manner. Finally, we demonstrated that S-phase DNA damage activated expression of PD-L1 in a STING-dependent manner. Conclusions: We propose a novel mechanism of immune infiltration in DDRD tumors, independent of neoantigen production. Activation of this pathway and associated PD-L1 expression may explain the paradoxical lack of T-cell-mediated cytotoxicity observed in DDRD tumors. We provide a rationale for exploration of DDRD in the stratification of patients for immune checkpoint-based therapies. PMID- 27707840 TI - Semen quality of young adult ICSI offspring: the first results. AB - STUDY QUESTION: What is the semen quality of young adult men who were conceived 18-22 years ago by ICSI for male infertility? SUMMARY ANSWER: In this cohort of 54 young adult ICSI men, median sperm concentration, total sperm count and total motile sperm count were significantly lower than in spontaneously conceived peers. WHAT IS KNOWN ALREADY: The oldest ICSI offspring cohort worldwide has recently reached adulthood. Hence, their reproductive health can now be investigated. Since these children were conceived by ICSI because of severe male factor infertility, there is reasonable concern that male offspring have inherited the deficient spermatogenesis from their fathers. Previously normal pubertal development and adequate Sertoli and Leydig cell function have been described in pubertal ICSI boys; however, no information on their sperm quality is currently available. STUDY DESIGN, SIZE, DURATION: This study was conducted at UZ Brussel between March 2013 and April 2016 and is part of a large follow-up project focussing on reproductive and metabolic health of young adults, between 18 and 22 years and conceived after ICSI with ejaculated sperm. Results of both a physical examination and semen analysis were compared between young ICSI men being part of a longitudinally followed cohort and spontaneously conceived controls who were recruited cross-sectionally. PARTICIPANTS/MATERIALS, SETTING, METHOD: Results of a single semen sample in 54 young adult ICSI men and 57 spontaneously conceived men are reported. All young adults were individually assessed, and the results of their physical examination were completed by questionnaires. Data were analysed by multiple linear and logistic regression, adjusted for covariates. In addition, semen parameters of the ICSI fathers dating back from their ICSI treatment application were analysed for correlations. MAIN RESULTS AND THE ROLE OF CHANCE: Young ICSI adults had a lower median sperm concentration (17.7 million/ml), lower median total sperm count (31.9 million) and lower median total motile sperm count (12.7 million) in comparison to spontaneously conceived peers (37.0 million/ml; 86.8 million; 38.6 million, respectively). The median percentage progressive and total motility, median percentage normal morphology and median semen volume were not significantly different between these groups. After adjustment for confounders (age, BMI, genital malformations, time from ejaculation to analysis, abstinence period), the statistically significant differences between ICSI men and spontaneously conceived peers remained: an almost doubled sperm concentration in spontaneously conceived peers in comparison to ICSI men (ratio 1.9, 95% CI 1.1-3.2) and a two fold lower total sperm count (ratio 2.3, 95% CI 1.3-4.1) and total motile count (ratio 2.1, 95% CI 1.2-3.6) in ICSI men compared to controls were found. Furthermore, compared to men born after spontaneous conception, ICSI men were nearly three times more likely to have sperm concentrations below the WHO reference value of 15 million/ml (adjusted odds ratio (AOR) 2.7; 95% CI 1.1-6.7) and four times more likely to have total sperm counts below 39 million (AOR 4.3; 95% CI 1.7-11.3). In this small group of 54 father-son pairs, a weak negative correlation between total sperm count in fathers and their sons was found. LIMITATIONS, REASONS FOR CAUTION: The main limitation is the small study population. Also, the results of this study where ICSI was performed with ejaculated sperm and for male-factor infertility cannot be generalized to all ICSI offspring because the indications for ICSI have nowadays been extended and ICSI is also being performed with non-ejaculated sperm and reported differences may thus either decrease or increase. WIDER IMPLICATIONS OF THE FINDINGS: These first results in a small group of ICSI men indicate a lower semen quantity and quality in young adults born after ICSI for male infertility in their fathers.

PMID- 27707839 TI - Development of a RNA-Seq Based Prognostic Signature in Lung Adenocarcinoma. AB - Background: Precision therapy for lung cancer will require comprehensive genomic testing to identify actionable targets as well as ascertain disease prognosis. RNA-seq is a robust platform that meets these requirements, but microarray derived prognostic signatures are not optimal for RNA-seq data. Thus, we undertook the first prognostic analysis of lung adenocarcinoma RNA-seq data and generated a prognostic signature. Methods: Lung adenocarcinoma RNA-seq and clinical data from The Cancer Genome Atlas (TCGA) were divided chronologically into training (n = 255) and validation (n = 157) cohorts. In the training cohort, prognostic association was assessed by univariate Cox analysis. A prognostic signature was built with stepwise multivariable Cox analysis. Outcomes by risk group, stage, and mutation status were analyzed with Kaplan-Meier and multivariable Cox analyses. All the statistical tests were two-sided. Results: In the training cohort, 96 genes had prognostic association with P values of less than or equal to 1.00x10-4, including five long noncoding RNAs (lncRNAs). Stepwise regression generated a four-gene signature, including one lncRNA. Signature high-risk cases had worse overall survival (OS) in the TCGA validation cohort (hazard ratio [HR] = 3.07, 95% confidence interval [CI] = 2.00 to 14.62) and a University of Michigan institutional cohort (n = 67; HR = 2.05, 95% CI = 1.18 to 4.55), and worse metastasis-free survival in the TCGA validation cohort (HR = 3.05, 95% CI = 2.31 to 13.37). The four-gene prognostic signature also statistically significantly stratified overall survival in important clinical subsets, including stage I (HR = 2.78, 95% CI = 1.91 to 11.13), EGFR wild-type (HR = 3.01, 95% CI = 1.73 to 14.98), and EGFR mutant (HR = 8.99, 95% CI = 62.23 to 141.44). The four-gene prognostic signature also stood out on top when compared with other prognostic signatures. Conclusions: Here, we present the first RNA-seq prognostic signature for lung adenocarcinoma that can provide a powerful prognostic tool for precision oncology as part of an integrated RNA-seq clinical sequencing program. PMID- 27707841 TI - Forty years of economic growth and plummeting mortality: the mortality experience of the poorly educated in South Korea. AB - BACKGROUND: South Korea has experienced rapid economic development and a substantial increase in life expectancy in an extremely short period. Whether this rapid development has been able to adequately address inequalities in health in South Korea may have important policy implications. This paper explores long term trends in inequalities in mortality related to education in South Korea between 1970 and 2010. METHODS: We used secondary data on population size and deaths in 1970 and 1980 from a previously published study, and census and death certificate data from Statistics Korea from 1990, 1995, 2000, 2005 and 2010. Trends in age-standardised mortality rates for men and women aged 25-64 according to education, as well as the rate ratio (RR), rate difference (RD), relative index of inequality (RII) and slope index of inequality (SII), were examined over the period 1970-2010. RESULTS: Despite overall mortality declines of 70-80% in the past 4 decades, educational inequalities have increased or been stagnant. There was minimal decline in mortality since 1970 in South Koreans with only a primary or lower level of education. The RR and RD between tertiary education and primary or lower education increased over the study period, while the RII and the SII in both genders remained stable. CONCLUSIONS: The South Korean experience over the past 40 years suggests that plummeting mortality rates and huge advances in education at the population level do not translate into reduced educational inequalities in mortality. PMID- 27707842 TI - Brain metastasis reirradiation in patients with advanced breast cancer. AB - The outcome of recurrent brain metastasis is dismal. This study aims to assess the clinical outcomes and toxicity of reirradiation as a salvage treatment for progressive brain metastasis in patients with advanced breast cancer. Between July 2005 and September 2014, the medical records of 56 patients with brain metastasis from breast cancer were retrospectively reviewed. Of these patients, 39 received whole-brain radiotherapy (WBRT) followed by stereotactic radiosurgery (SRS) reirradiation (Group 1), and 17 received SRS followed by WBRT reirradiation (Group 2). Overall survival (OS) and brain progression-free survival rates/times were calculated using the Kaplan-Meier method. Prognostic factors were evaluated using the Cox proportional hazards model. Change in neurologic function was also assessed. The median OS was 10.8 months (range, 1.3-56.8 months). In Group 1, the median PFS time (PFS-1) was 6.5 months and the OS time was 11.4 months. Multivariate analysis revealed that longer OS was significantly associated with a high Karnofsky performance score (KPS) (P = 0.004), controlled extracranial metastasis (P = 0.001) and a good response to reirradiation (P = 0.034). In Group 2, the median PFS time (PFS-2) after reirradiation was 8.5 months and the OS time was 10.8 months. Multivariate analysis revealed that longer OS was significantly associated with a high KPS (P = 0.018). The majority of the patients had improved or stable neurological function. Reirradiation is an effective and a safe treatment for patients with brain metastases from breast cancer. It might delay the progression of intracranial disease and improve neurological function. A suitable patient selection for reirradiation was suggested. PMID- 27707844 TI - A Forum for What's Important. PMID- 27707843 TI - Adjuvant Therapy for Resected Gallbladder Cancer: Analysis of the National Cancer Data Base. AB - Background: Management of resected gallbladder cancer relies on single-arm trials and retrospective observations. Our objective was to evaluate adjuvant therapy in a nationwide data set using causal inference methods to address sources of bias. Methods: We studied patients with T2-3 or node-positive, nonmetastatic gallbladder cancer, resected with grossly negative margins and reported to the National Cancer Data Base between 2004 and 2011. We defined adjuvant therapy as any chemotherapy within 90 days of surgery, and upfront concurrent chemoradiation as radiation within 14 days of first chemotherapy. After adjusting for missing data and guarantee-time bias, and using propensity score analysis to minimize indication bias, we compared overall survival of patients receiving adjuvant therapies with untreated case subjects. Results: Adjuvant chemotherapy was administered to 28.8% of 4775 patients, and upfront chemoradiation to 13.5%. Treatment was less frequent among patients who were older, patients with comorbidities, and among white Hispanic women. T3 or node-positive disease, microscopically positive margins, or extended resection increased the likelihood of adjuvant therapy. Overall survival at three years was 39.9% (95% confidence interval [CI] = 38.4% to 41.4%) and was unaffected by adjuvant therapy after adjusting for multiple confounders (hazard ratio = 1.01, 95% CI = 0.92 to 1.10). Patients with T3 or node-positive tumors treated with upfront adjuvant chemoradiation had a modest early survival advantage (absolute difference at two years = 6.8%, 95% CI = 1.1% to 12.6%), but survival curves converged after five years of follow-up. Conclusions: The curative potential of current adjuvant therapy in gallbladder cancer is questionable, justifying placebo-controlled investigation of novel chemotherapy combinations or alternative approaches. Chemoradiation may provide a short-term benefit in locally advanced tumors. PMID- 27707845 TI - The Objective Measurement of Brace-Use Adherence in the Treatment of Idiopathic Clubfoot. AB - BACKGROUND: A successful outcome for the treatment of idiopathic clubfoot is believed to require adequate adherence to brace use. Previous studies have relied on parental reporting of brace application. We used temperature sensors to determine the adherence to the bracing protocol, the accuracy of parent-reported use, and differences in adherence between patients who experienced relapse of deformity and those who did not. METHODS: Using wireless sensors attached to brace sandals, we monitored brace wear over a 3-month period in this cross sectional study involving 48 patients in 4 age-based groups: 6 to 12 months (Group 1), >1 to 2 years (Group 2), >2 to 3 years (Group 3), and >3 to 4 years (Group 4). Parents were blinded to the purpose of the sensors. The mean number of hours of daily brace use as measured by the sensors was compared with the physician-recommended hours and parent-reported hours of brace use. RESULTS: Sensors were retrieved from 44 of 48 patients. Overall, the median brace use recorded by the sensors was 62% (range, 5% to 125%) of that recommended by the physician, and 77% (range, 6% to 213%) of that reported by the parents. For Groups 1 to 3, the difference between the physician-recommended and measured number of hours of daily brace use was significant (p <= 0.002), and the difference between the parent-reported and measured number of hours of daily brace use was also significant (p <= 0.013). Eight (18%) of the 44 patients who completed the study experienced relapse during the period of monitoring; most importantly, the mean number of hours of brace wear for these patients, 5 hours per day (median, 4; and standard deviation [SD], 3 hours per day) was significantly lower than the 8 hours per day for those who did not experience relapse (median, 9; and SD, 5 hours per day) (p = 0.045). CONCLUSIONS: The present study objectively quantified the number of daily hours of post-corrective brace wear for patients with clubfoot in varying age groups and provides an estimate of the number of hours required to avoid relapse.

PMID- 27707846 TI - Radiographic Changes in the Cervical Spine Following Anterior Arthrodesis: A Long Term Analysis of 166 Patients. AB - BACKGROUND: Adjacent segment degeneration frequently develops following anterior cervical discectomy and fusion. The objectives of the present study were to characterize the long-term evolution of degenerative radiographic changes at segments adjacent to anterior cervical fusion and to identify factors associated with the development of these changes, including the preoperative condition of the cervical spine and parameters related to arthrodeses. METHODS: One hundred and sixty-six patients who underwent anterior cervical discectomy and fusion for symptomatic cervical spondylosis or disc herniation were followed radiographically for a mean time of 12.7 years (range, 5 to 30 years). Radiographic changes representing degeneration at adjacent levels, including disc height loss, osteophyte formation, end-plate sclerosis, and facet arthrosis, along with changes in sagittal alignment of the fusion segment and cervical spine, were recorded preoperatively and at the time of the latest follow-up. Regression models were used to identify the parameters that affect these degenerative changes. RESULTS: More than 90% of patients had worsened anterior and posterior osteophytes at segments immediately adjacent to the fusion. Degenerative changes were significantly affected by the proximity of the level to the fusion and were inversely affected by the preoperative degenerative changes present at the segment (p < 0.0001). The time elapsed since the surgical procedure was a significant predictor of degenerative changes (p < 0.0001). However, the patient age, the number of levels fused, and the sagittal alignment of the fusion segment had no influence on the degenerative changes at adjacent segments. CONCLUSIONS: Multiple factors likely contribute to adjacent segment degeneration following cervical arthrodesis. Although mechanical parameters associated with arthrodesis, such as length and alignment of the fusion, did not appear to play a role, the preoperative degenerative condition of the spine and inclusion of C5-C6 in the arthrodesis influenced the incidence of adjacent segment degeneration.

PMID- 27707847 TI - Cardiopulmonary Exercise Testing in Patients with Idiopathic Scoliosis. AB - BACKGROUND: Scoliosis causes impairment of the respiratory and cardiovascular systems. Traditional pulmonary function tests only examine patients under static conditions. The aim of our study was to investigate the correlation between radiographic parameters and dynamic cardiopulmonary capacity in patients with idiopathic scoliosis. METHODS: Forty patients with idiopathic scoliosis were included in this prospective study from January 2014 to February 2016. The patients underwent full radiographic assessment of deformity, pulmonary function testing, and cardiopulmonary bicycle ergometer testing. The impact of the severity of thoracic curvature and kyphosis on pulmonary function and physical capacity was investigated. RESULTS: Thirty-three female patients with a mean age of 15.5 years (range, 11 to 35 years) and coronal thoracic curvature of 49.4 degrees (range, 24 degrees to 76 degrees ) and 7 male subjects with a mean age of 15.9 years (range, 13 to 18 years) and coronal thoracic curvature of 47.1 degrees (range, 22 degrees to 80 degrees ) were included. No correlation was found between coronal thoracic curvature and pulmonary function test results in the female patients. Female patients with a thoracic curve of >=60 degrees had lower blood oxygen saturation at maximal exercise in the cardiopulmonary exercise test (p = 0.032). Female patients with a thoracic curve of >=50 degrees had a higher respiratory rate (p = 0.041) and ventilation volume per minute (p = 0.046) and lower breathing reserve at maximal exercise (p = 0.038). Thoracic kyphosis in female patients was positively correlated with pulmonary function, as shown by the forced expiratory volume in 1 second (r = 0.456, p = 0.01), forced vital capacity (r = 0.366, p = 0.043), vital capacity (r = 0.525, p = 0.006), and total lung capacity (r = 0.388, p = 0.031), as well as with tidal volume (r = 0.401, p = 0.025) in cardiopulmonary exercise testing. Female patients who engaged in regular exercise had better peak oxygen intake normalized by body weight (p < 0.001), peak oxygen intake normalized by the predicted value (p = 0.003), maximum heart rate (p = 0.020), and heart rate reserve (p = 0.014). CONCLUSIONS: Overall exercise tolerance was not correlated with the magnitude of the thoracic curve and kyphosis. Some parameters of ventilatory function and pulmonary gas exchange worsened as thoracic curvature increased or kyphosis decreased. Exercise capacity was better in patients who engaged in regular aerobic exercise, and physical activity is recommended for patients with idiopathic scoliosis. LEVEL OF EVIDENCE: Prognostic Level III.

PMID- 27707848 TI - Functional Outcomes After Operative Management of Extra-Articular Glenoid Neck and Scapular Body Fractures. AB - BACKGROUND: This study's purpose was to assess patient-based functional outcomes following open reduction and internal fixation (ORIF) of displaced scapular body and glenoid neck fractures. This series represents a 9-year experience at a level I trauma center and referral destination for this injury. METHODS: A database was established to record surgical and functional outcomes of scapular fractures treated with ORIF. For this report, the cases of all patients who had a glenoid neck or scapular body fracture (AO/OTA 14-A3 or 14-C1) without intra-articular involvement were reviewed. Operative indications included medial/lateral displacement of >=20 mm, angulation of >=45 degrees , medial/lateral displacement of >=15 mm with angulation of >=30 degrees , double disruptions of the superior shoulder suspensory complex with both displaced >=10 mm, a glenopolar angle of <=22 degrees , and an open fracture. The results of clinical testing, including measurements of range of motion and strength and scores on the Disabilities of the Arm, Shoulder and Hand (DASH) and Short Form-36 (SF-36) questionnaires, were recorded at each follow-up appointment. RESULTS: Between 2002 and 2011, 61 patients with an extra-articular scapular fracture were treated surgically within 20 days after the injury; 19 patients (31%) had >=2 operative indications. Of the 61 patients, 49 (80%) were followed for >=1 year (mean, 33 months; range, 12 to 138 months) following surgery. There was a 100% union rate at the time of final follow-up, with a mean DASH score of 12.1 points (range, 0 to 54 points). For all parameters, the mean SF-36 scores of the study patients were comparable with normative population scores. The range of motion of the operatively treated and contralateral shoulders averaged, respectively, 154 degrees and 159 degrees of forward flexion, 106 degrees and 108 degrees of abduction, and 66 degrees and 70 degrees of external rotation. The strength of the operatively treated and contralateral shoulders averaged, respectively, 20 and 23 lb (89.0 and 102.3 N) of force in forward flexion, 14 and 16 lb (62.3 and 71.2 N) in abduction, and 19 and 23 lb (84.5 and 102.3 N) in external rotation. Complications and/or secondary surgery were recorded for 8 patients (16%). CONCLUSIONS: Displaced scapular body and glenoid neck fractures that meet current published standards for ORIF can be treated operatively with predictably good functional outcomes.

PMID- 27707849 TI - Outcome of Revision Shoulder Arthroplasty After Resurfacing Hemiarthroplasty in Patients with Glenohumeral Osteoarthritis. AB - BACKGROUND: Patients are often treated with a resurfacing hemiarthroplasty in the expectation that the bone-preserving design facilitates revision should the need for a revision arthroplasty arise. The aim of this study was to report the outcome of patients with glenohumeral osteoarthritis who underwent revision shoulder arthroplasty after resurfacing hemiarthroplasty. METHODS: We reviewed all patients with osteoarthritis reported to the Danish Shoulder Arthroplasty Registry from 2006 to 2013. There were 1,210 primary resurfacing hemiarthroplasties, of which 107 cases (9%) required a revision surgical procedure, defined as the removal or exchange of the humeral component or the addition of a glenoid component. The Western Ontario Osteoarthritis of the Shoulder (WOOS) index was used to evaluate outcome at 1 year. RESULTS: The median WOOS of revision arthroplasty after failed resurfacing hemiarthroplasty was 62 points (interquartile range, 40 to 88 points). Of the 80 cases that had follow up, 33 (41%) had an unacceptable outcome, defined as a WOOS of <=50 points. Of the 107 cases that required a revision surgical procedure, 11 arthroplasties (10%) required a further revision surgical procedure. The resurfacing hemiarthroplasty was revised to a stemmed hemiarthroplasty (n = 39), anatomic total shoulder arthroplasty (n = 31), or reverse shoulder arthroplasty (n = 30). In 7 cases, the revision arthroplasty design was unknown. The median WOOS of patients who underwent revision stemmed hemiarthroplasty (48 points) was significantly inferior (p = 0.002) to that of patients who underwent primary stemmed hemiarthroplasty (75 points); the median WOOS of patients who underwent revision anatomic total shoulder arthroplasty (74 points) was also significantly inferior (p = 0.007) to that of patients who underwent primary anatomic total shoulder arthroplasty (93 points). However, the median WOOS of patients who underwent revision reverse shoulder arthroplasty (68 points) was not significantly different (p = 0.66) from that of patients who underwent primary reverse shoulder arthroplasty (77 points) used in the treatment of osteoarthritis. CONCLUSIONS: The outcome of revision shoulder arthroplasty after failed resurfacing hemiarthroplasty was variable and, in many cases, disappointing. It is important that resurfacing hemiarthroplasty is used for the correct indications and with adequate technique and skill. When resurfacing hemiarthroplasty is used in the treatment of osteoarthritis, revision cannot be counted upon as a fallback. LEVEL OF EVIDENCE: Therapeutic Level II.

PMID- 27707850 TI - The Accuracy of Imaging Techniques in the Assessment of Periprosthetic Hip Infection: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Various imaging techniques are used for excluding or confirming periprosthetic hip infection, but there is no consensus regarding the most accurate technique. The objective of this study was to determine the accuracy of current imaging modalities in diagnosing periprosthetic hip infection. METHODS: A systematic review and meta-analysis of the literature was conducted with a comprehensive search of MEDLINE and Embase to identify clinical studies in which periprosthetic hip infection was investigated with different imaging modalities. The sensitivity and specificity of each imaging technique were determined and compared with the results of microbiological and histological analysis, intraoperative findings, and clinical follow-up of >6 months. RESULTS: A total of 31 studies, published between 1988 and 2014, were included for meta-analysis, representing 1,753 hip prostheses. Quality assessment of the included studies identified low concerns with regard to external validity but more concerns with regard to internal validity including risk of bias (>50% of studies had insufficient information). No meta-analysis was performed for radiography, ultrasonography, computed tomography, and magnetic resonance imaging because of insufficient available clinical data. The pooled sensitivity and specificity were 88% (95% confidence interval [CI], 81% to 94%) and 92% (95% CI, 88% to 96%), respectively, for leukocyte scintigraphy; 86% (95% CI, 80% to 90%) and 93% (95% CI, 90% to 95%) for fluorodeoxyglucose positron emission tomography (FDG PET); 69% (95% CI, 58% to 79%) and 96% (95% CI, 93% to 98%) for combined leukocyte and bone marrow scintigraphy; 84% (95% CI, 70% to 93%) and 75% (95% CI, 66% to 82%) for antigranulocyte scintigraphy; and 80% (95% CI, 72% to 86%) and 69% (95% CI, 64% to 73%) for bone scintigraphy. CONCLUSIONS: Of the currently used imaging techniques, leukocyte scintigraphy has satisfactory accuracy in confirming or excluding periprosthetic hip infection. Although not significantly different, combined leukocyte and bone marrow scintigraphy was the most specific imaging technique. FDG PET has an appropriate accuracy in confirming or excluding periprosthetic hip infection, but may not yet be the preferred imaging modality because of limited availability and relatively higher cost.

PMID- 27707852 TI - Microstructural and Mechanical Properties of the Posterior Cruciate Ligament: A Comparison of the Anterolateral and Posteromedial Bundles. AB - BACKGROUND: The microstructural organization (collagen fiber alignment) of the posterior cruciate ligament (PCL), which likely corresponds with its functional properties, has only been described qualitatively in the literature, to our knowledge. The goal of this study was to quantify the tensile mechanical and microstructural properties of the PCL and compare these qualities between the anterolateral and posteromedial bundles. METHODS: Twenty-two knee specimens from 13 donors (8 male and 5 female; mean age [and standard deviation] at the time of death, 43.0 +/- 4.1 years; mean body mass index, 30.0 +/- 6.7 kg/m2) were dissected to isolate the PCL, and each bundle was split into 3 regions. Mechanical testing of each regional sample consisted of preconditioning followed by a ramp-and-hold stress-relaxation test and a quasi-static ramp-to-failure test. Microstructural analysis was performed with use of a high-resolution, division-of-focal-plane polarization camera to evaluate the average direction of collagen orientation and the degree to which the collagen fibers were aligned in that direction. Results were compared between the anterolateral and posteromedial bundles and across the regions of each bundle. RESULTS: The anterolateral and posteromedial bundles demonstrated largely equivalent mechanical and microstructural properties. Elastic moduli in the toe and linear regions were not different; however, the posteromedial bundle did show significantly more stress relaxation (p = 0.004). There were also few differences in microstructural properties between bundles, which again were seen only in stress relaxation. Comparing regions within each bundle, several mechanical and microstructural parameters showed significant relationships across the posteromedial bundle, following a gradient of decreasing strength and alignment from anterior to posterior. CONCLUSIONS: The PCL has relatively homogenous microstructural and mechanical properties, with few differences between the anterolateral and posteromedial bundles. This finding suggests that distinct functions of the PCL bundles result primarily from size and anatomical location rather than from differences in these properties. CLINICAL RELEVANCE: These properties of the PCL can be used to assess the utility of graft choices and operative techniques for PCL reconstruction and may partly explain limited differences in the outcomes of single-bundle compared with double-bundle reconstruction techniques for the PCL. PMID- 27707851 TI - The Michigan Experience with Safety and Effectiveness of Tranexamic Acid Use in Hip and Knee Arthroplasty. AB - BACKGROUND: The efficacy of tranexamic acid (TXA) in reducing blood loss and transfusion requirements in total hip and knee arthroplasty has been well established in small controlled clinical trials and meta-analyses. The purpose of the current study was to determine the risks and benefits of TXA use in routine orthopaedic surgical practice on the basis of data from a large, statewide arthroplasty registry. METHODS: From April 18, 2013, to September 30, 2014, there were 23,236 primary total knee arthroplasty cases and 11,489 primary total hip arthroplasty cases completed and registered in the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI). We evaluated the association between TXA use and hemoglobin drop, transfusion, length of stay (LOS), venous thromboembolism (VTE), readmission, and cardiovascular events by fitting mixed effects generalized linear and mixed-effects Cox models. We used inverse probability of treatment weighting to enhance causal inference. RESULTS: For total hip arthroplasty, TXA use was associated with a smaller drop in hemoglobin (mean difference = -0.65 g/dL; 95% confidence interval [CI] = -0.60 to -0.71 g/dL), decreased odds of blood transfusion (odds ratio [OR] = 0.72; 95% CI = 0.60 to 0.86), and decreased readmissions (OR = 0.77; 95% CI = 0.64 to 0.93) compared with no TXA use. There was no effect on VTE (hazard ratio [HR] = 0.91; 95% CI = 0.62 to 1.33), LOS (incident rate ratio [IRR] = 1.00; 95% CI = 0.97 to 1.03), or cardiovascular events (OR = 0.85; 95% CI = 0.47 to 1.52). For total knee arthroplasty, TXA was associated with a smaller drop in hemoglobin (mean difference = -0.68 g/dL; 95% CI = -0.64 to -0.71 g/dL) and one-fourth the odds of blood transfusion (OR = 0.26; 95% CI = 0.21 to 0.31). There was an association with decreased risk of VTE within 90 days after surgery (HR = 0.56; 95% CI = 0.42 to 0.73), slightly decreased LOS (IRR = 0.93; 95% CI = 0.92 to 0.95), and no association with readmissions (OR = 0.90; 95% CI = 0.79 to 1.04) or cardiovascular events (OR = 1.12; 95% CI = 0.74 to 1.71). CONCLUSIONS: In routine orthopaedic surgery practice, TXA use was associated with decreased blood loss and transfusion risk for both total knee and total hip arthroplasty, without evidence of increased risk of complications. TXA use was also associated with reduced risk of readmission among total hip arthroplasty patients and reduced risk of VTE among total knee arthroplasty patients, and did not have an adverse effect on cardiovascular complications in either group.

PMID- 27707854 TI - What's Important: The Unhappy Patient. PMID- 27707855 TI - The Age of OrthoInfo: A Randomized Controlled Trial Evaluating Patient Comprehension of Informed Consent. AB - BACKGROUND: Integral to an orthopaedic surgeon-patient informed consent discussion is the assessment of patient comprehension of their medical care. However, little is known about how to optimize patient comprehension of an informed consent discussion. The purpose of our study was to evaluate three time controlled informed consent discussion methods to determine which optimized patient comprehension immediately after the discussion. METHODS: Sixty-seven consecutive patients with knee osteoarthritis who were considered medically appropriate for a knee corticosteroid injection were enrolled in our trial. Participants were randomized and were allocated into one of three groups in a parallel fashion and 1:1:1 ratio. Our three groups varied by sensory input and included verbal (hearing), verbal and video (hearing and sight), and verbal and model (hearing, sight, and touch). Each participant listened to a 10-minute scripted lecture given by a researcher; this lecture was based on content from the American Academy of Orthopaedic Surgeons patient education web site OrthoInfo. Patient comprehension was assessed after the lecture using a validated questionnaire called the Nkem test. Our primary outcome evaluated patient comprehension utilizing a pairwise comparison of mean comprehension scores between the groups. The primary outcome was analyzed using a one-way analysis of variance with the least significant difference calculated post hoc and a 95% confidence interval (95% CI). The health-care staff, study participants, and outcome assessor were each blinded to group assignments. RESULTS: The mean comprehension scores were 84% (95% CI, 79% to 88%) for the verbal and model group, 74% (95% CI, 63% to 80%) for the verbal and video group, and 71% (95% CI, 61% to 80%) for the verbal group. The omnibus analysis of variance was significant and showed a difference among the groups (p = 0.019). The pairwise comparison of the groups using the least significant difference calculated post hoc showed that the verbal and model group outperformed the verbal group (p = 0.01) and the verbal and video group (p = 0.023). CONCLUSIONS: Multisensory patient education incorporating OrthoInfo and an anatomic model optimized patient comprehension immediately after a time-controlled informed consent discussion. This finding could play an important role in improving surgeon-patient communication in the field of orthopaedic surgery. PMID- 27707856 TI - The Early Impact of an Administrative Processing Fee on Manuscript Submissions at The Journal of Bone & Joint Surgery. AB - BACKGROUND: There was a dramatic increase in the volume of manuscripts submitted to The Journal of Bone & Joint Surgery (JBJS) between 2009 and 2012. This resulted in increased journal administrative costs. To offset this financial burden, in May 2013, JBJS started charging authors an administrative processing fee at the time of submission. The purpose of this study was to assess the impact of the administrative fee on the volume and characteristics of manuscripts submitted to JBJS. METHODS: Our analysis included 866 manuscripts submitted to JBJS between November 2012 and November 2013. We compared manuscripts submitted 6 months prior to fee implementation and prior to the announcement (denoted as the baseline group), in the several months prior to fee implementation but after the fee implementation announcement (denoted as the fee announcement group), and in the 6 months after fee implementation (denoted as the fee implementation group). Manuscripts were reviewed for institutional and author demographic characteristics, as well as for general study characteristics. RESULTS: In the first full calendar year (2014) after the implementation of the fee, the annual volume of submissions to JBJS declined by 33.5% compared with the annual submission volume in 2010 to 2012. In a comparative analysis, the geographical region of origin (p = 0.003), level of evidence (p < 0.0001), funding, and specialty differed between the 3 submission periods. However, subgroup analyses demonstrated that differences were attributable to the fee announcement group and that there were few important differences between the baseline and fee implementation groups. Reporting of funding information improved significantly between the baseline and fee implementation groups; in the post-fee implementation period, studies were more likely to have declared no external funding source (p = 0.001). CONCLUSIONS: The administrative processing fee at JBJS has been associated with a decrease in submission volume, but, overall, there has not been a change in the characteristics of studies submitted. However, decreased overall volume implies a decrease in the absolute number of high-level studies submitted to the journal. Administrative processing fees at high-volume journals may be a financially viable way to offset high administrative costs without substantially changing the characteristics of submitted articles. PMID- 27707857 TI - Measuring Quality of Care with Patient Satisfaction Scores. AB - Quality of care is a multidimensional concept encompassing safety, efficiency, outcomes, and the patient experience. Traditional quality metrics, such as mortality rates, complication rates, and patient-reported outcomes, are time consuming and cost-consuming to obtain and risk-stratify. The implications of reimbursement related to patient satisfaction and the ease of data collection have contributed to the perception that satisfaction is a global indicator of health-care quality; however, high satisfaction scores are not consistently correlated with traditional outcome and safety indicators. Higher patient satisfaction may be associated with increased costs of care. Costs may be further increased by the implementation of the satisfaction surveys themselves, which can increase imaging studies and prescriptions. Therefore, satisfaction surveys are not appropriate measures of overall quality of care. Accurate assessment of quality requires a multidimensional approach that includes specific measures for each domain. PMID- 27707858 TI - Post-Interview Communication During Application to Orthopaedic Surgery Residency Programs. AB - BACKGROUND: Post-interview communication from residency programs to applicants is common during the U.S. residency match process. The goals of this study were to understand the frequency and type of post-interview communication, how this communication influences applicants' ranking of programs, whether programs use "second-look" visits to gauge or to encourage applicant interest, and the financial costs to applicants of second-look visits. METHODS: A post-match survey was sent to 1,198 applicants to one academic orthopaedic residency program over 2 years. The response rates were 15% in 2014 and 31% in 2015, totaling 293 responses used for analysis. RESULTS: Sixty-four percent of applicants reported having post-interview communication with one or more programs. Seventeen percent said that communication caused them to rank the contacting program higher or to keep the program ranked as number 1. Twenty percent felt pressured to reveal their rank position, and 8% were asked to rank a program first in exchange for the program's promise to rank the applicant first. Applicants who received post interview communication had odds that were 13.5 times higher (95% confidence interval, 6.2 to 30 times higher) of matching to the programs that contacted them. Ninety percent of applicants said that communication from a program did not change how they ranked the program with which they eventually matched. Seventeen percent were encouraged to attend second-look visits, incurring a mean cost of $600 (range, $20 to $8,000). CONCLUSIONS: Orthopaedic residency programs continue to communicate with applicants in ways that violate the National Resident Matching Program's Match Communication Code of Conduct, and they continue to encourage second-look visits. To improve the integrity of the match, we suggest that programs use no-reply e-mails to minimize influence and pressure on applicants, interviewers and applicants review the Code of Conduct on interview day and provide instructions on reporting violations to the National Resident Matching Program, all post-interview communication be directed to a standardized or neutral third party, and programs actively discourage second-look visits and stop requiring second-look visits.

PMID- 27707861 TI - Erratum. PMID- 27707863 TI - Wolbachia increases the susceptibility of a parasitoid wasp to hyperparasitism. AB - The success of maternally transmitted endosymbiotic bacteria, such as Wolbachia, is directly linked to their host reproduction but in direct conflict with other parasites that kill the host before it reaches reproductive maturity. Therefore, symbionts that have evolved strategies to increase their host's ability to evade lethal parasites may have high penetrance, while detrimental symbionts would be selected against, leading to lower penetrance or extinction from the host population. In a natural population of the parasitoid wasp Hyposoter horticola in the Aland Islands (Finland), the Wolbachia strain wHho persists at an intermediate prevalence (~50%). Additionally, there is a negative correlation between the prevalence of Wolbachia and a hyperparasitoid wasp, Mesochorus cf. stigmaticus, in the landscape. Using a manipulative field experiment, we addressed the persistence of Wolbachia at this intermediate level, and tested whether the observed negative correlation could be due to Wolbachia inducing either susceptibility or resistance to parasitism. We show that infection with Wolbachia does not influence the ability of the wasp to parasitize its butterfly host, Melitaea cinxia, but that hyperparasitism of the wasp increases in the presence of wHho. Consequently, the symbiont is detrimental, and in order to persist in the host population, must also have a positive effect on fitness that outweighs the costly burden of susceptibility to widespread parasitism. PMID- 27707862 TI - Understanding how animal groups achieve coordinated movement. AB - Moving animal groups display remarkable feats of coordination. This coordination is largely achieved when individuals adjust their movement in response to their neighbours' movements and positions. Recent advancements in automated tracking technologies, including computer vision and GPS, now allow researchers to gather large amounts of data on the movements and positions of individuals in groups. Furthermore, analytical techniques from fields such as statistical physics now allow us to identify the precise interaction rules used by animals on the move. These interaction rules differ not only between species, but also between individuals in the same group. These differences have wide-ranging implications, affecting how groups make collective decisions and driving the evolution of collective motion. Here, I describe how trajectory data can be used to infer how animals interact in moving groups. I give examples of the similarities and differences in the spatial and directional organisations of animal groups between species, and discuss the rules that animals use to achieve this organisation. I then explore how groups of the same species can exhibit different structures, and ask whether this results from individuals adapting their interaction rules. I then examine how the interaction rules between individuals in the same groups can also differ, and discuss how this can affect ecological and evolutionary processes. Finally, I suggest areas of future research. PMID- 27707865 TI - Testosterone activates sexual dimorphism including male-typical carotenoid but not melanin plumage pigmentation in a female bird. AB - In males it is frequently testosterone (T) that activates the expression of sexually selected morphological and behavioral displays, but the role of T in regulating similar traits in females is less clear. Here, we combine correlational data with results from T and gonadotropin-releasing hormone (GnRH) manipulations in both sexes to assess the role of T in mediating sexually dimorphic coloration and morphology in the red-backed fairy-wren (Malurus melanocephalus). We show that: (1) natural variation in female expression of ornamental traits (darkened bills and red back feathers) is positively associated with age and circulating androgen titres, (2) females have the capacity to express most male-typical traits in response to exogenous T, including carotenoid pigmented body plumage, shorter feathers, darkened bill and enlarged cloacal protuberance, but (3) appear constrained in production of male-typical melanin pigmented plumage, and (4) low androgen levels during the pre-nuptial molt, probably because of low ovarian capacity for steroid production (or luteinizing hormone sensitivity), prevent females from developing male-like ornamentation. Thus, females appear to retain molecular mechanisms for hormonally regulated male typical ornamentation, although these are rarely activated because of insufficient production of the hormonal signal. PMID- 27707864 TI - Voltage-gated calcium channels of Paramecium cilia. AB - Paramecium cells swim by beating their cilia, and make turns by transiently reversing their power stroke. Reversal is caused by Ca2+ entering the cilium through voltage-gated Ca2+ (CaV) channels that are found exclusively in the cilia. As ciliary Ca2+ levels return to normal, the cell pivots and swims forward in a new direction. Thus, the activation of the CaV channels causes cells to make a turn in their swimming paths. For 45 years, the physiological characteristics of the Paramecium ciliary CaV channels have been known, but the proteins were not identified until recently, when the P. tetraurelia ciliary membrane proteome was determined. Three CaValpha1 subunits that were identified among the proteins were cloned and confirmed to be expressed in the cilia. We demonstrate using RNA interference that these channels function as the ciliary CaV channels that are responsible for the reversal of ciliary beating. Furthermore, we show that Pawn (pw) mutants of Paramecium that cannot swim backward for lack of CaV channel activity do not express any of the three CaV1 channels in their ciliary membrane, until they are rescued from the mutant phenotype by expression of the wild-type PW gene. These results reinforce the correlation of the three CaV channels with backward swimming through ciliary reversal. The PwB protein, found in endoplasmic reticulum fractions, co-immunoprecipitates with the CaV1c channel and perhaps functions in trafficking. The PwA protein does not appear to have an interaction with the channel proteins but affects their appearance in the cilia. PMID- 27707866 TI - Metabolic recovery from drowning by insect pupae. AB - Many terrestrial insects live in environments that flood intermittently, and some life stages may spend days underwater without access to oxygen. We tested the hypothesis that terrestrial insects with underground pupae show respiratory adaptations for surviving anoxia and subsequently reestablishing normal patterns of respiration. Pupae of Manduca sexta were experimentally immersed in water for between 0 and 13 days. All pupae survived up to 5 days of immersion regardless of whether the water was aerated or anoxic. By contrast, fifth-instar larvae survived a maximum of 4 h of immersion. There were no effects of immersion during the pupal period on adult size and morphology. After immersion, pupae initially emitted large pulses of CO2 After a subsequent trough in CO2 emission, spiracular activity resumed and average levels of CO2 emission were then elevated for approximately 1 day in the group immersed for 1 day and for at least 2 days in the 3- and 5-day immersion treatments. Although patterns of CO2 emission were diverse, most pupae went through a period during which they emitted CO2 in a cyclic pattern with periods of 0.78-2.2 min. These high-frequency cycles are not predicted by the recent models of Forster and Hetz (2010) and Grieshaber and Terblanche (2015), and we suggest several potential ways to reconcile the models with our observations. During immersion, pupae accumulated lactate, which then declined to low levels over 12-48 h. Pupae in the 3- and 5-day immersion groups still had elevated rates of CO2 emission after 48 h, suggesting that they continued to spend energy on reestablishing homeostasis even after lactate had returned to low levels. Despite their status as terrestrial insects, pupae of M. sexta can withstand long periods of immersion and anoxia and can reestablish homeostasis subsequently. PMID- 27707867 TI - The diversity and evolution of locomotor muscle properties in anurans. AB - Anuran jumping is a model system for linking muscle physiology to organismal performance. However, anuran species display substantial diversity in their locomotion, with some species performing powerful leaps from riverbanks or tree branches, while other species move predominantly via swimming, short hops or even diagonal-sequence gaits. Furthermore, many anurans with similar locomotion and morphology are actually convergent (e.g. multiple independent evolutions of 'tree frogs'), while closely related species may differ drastically, as with the walking toad (Melanophryniscus stelzneri) and bullfrog-like river toad (Phrynoides aspera) compared with other Bufonid toads. These multiple independent evolutionary changes in locomotion allow us to test the hypothesis that evolutionary increases in locomotor performance will be linked to the evolution of faster, high-power muscles. I tested the jumping, swimming and walking (when applicable) performance of 14 species of anurans and one salamander, followed by measurement of the contractile properties of the semimembranosus and plantaris longus muscles and anatomical measurements, using phylogenetic comparative methods. I found that increased jumping performance correlated to muscle contractile properties associated with muscle speed (e.g. time to peak tetanus, maximum shortening speed, peak isotonic power), and was tightly linked to relevant anatomical traits (e.g. leg length, muscle mass). Swimming performance was not correlated to jumping, and was correlated with fewer anatomical and muscular variables. Thus, muscle properties evolve along with changes in anatomy to produce differences in overall locomotor performance. PMID- 27707870 TI - Trends in epilepsy surgery: stable surgical numbers despite increasing presurgical volumes. AB - INTRODUCTION: Despite the success of epilepsy surgery, recent reports suggest a decline in surgical numbers. We tested these trends in our cohort to elucidate potential reasons. PATIENTS AND METHODS: Presurgical, surgical and postsurgical data of all patients undergoing presurgical evaluation in between 1990 and 2013 were retrospectively analysed. Patients were grouped according to the underlying pathology. RESULTS: A total of 3060 patients were presurgically studied, and resective surgery was performed in 66.8% (n=2044) of them: medial temporal sclerosis (MTS): n=675, 33.0%; benign tumour (BT): n=408, 20.0%; and focal cortical dysplasia (FCD): n=284, 13.9%. Of these, 1929 patients (94.4%) had a follow-up of 2 years, and 50.8% were completely seizure free (Engel IA). Seizure freedom rate slightly improved over time. Presurgical evaluations continuously increased, whereas surgical interventions did not. Numbers for MTS, BT and temporal lobe resections decreased since 2009. The number of non-lesional patients and the need for intracranial recordings increased. More evaluated patients did not undergo surgery (more than 50% in 2010-2013) because patients were not suitable (mainly due to missing hypothesis: 4.5% in 1990-1993 up to 21.1% in 2010-2013, total 13.4%) or declined from surgery (maximum 21.0% in 2010 2013, total 10.9%). One potential reason may be that increasingly detailed information on chances and risks were given over time. CONCLUSIONS: The increasing volume of the presurgical programme largely compensates for decreasing numbers of surgically remediable syndromes and a growing rate of informed choice against epilepsy surgery. Although comprehensive diagnostic evaluation is offered to a larger group of epilepsy patients, surgical numbers remain stable. PMID- 27707869 TI - A work observation study of nuclear medicine technologists: interruptions, resilience and implications for patient safety. AB - BACKGROUND: Errors by nuclear medicine technologists during the preparation of radiopharmaceuticals or at other times can cause patient harm and may reflect the impact of interruptions, busy work environments and deficient systems or processes. We aimed to: (a) characterise the rate and nature of interruptions technologists experience and (b) identify strategies that support safety. METHODS: We performed 100 hours of observation of 11 technologists at a major public hospital and measured the proportions of time spent in eight categories of work tasks, location of task, interruption rate and type and multitasking (tasks conducted in parallel). We catalogued specific safety-oriented strategies used by technologists. RESULTS: Technologists completed 5227 tasks and experienced 569 interruptions (mean, 4.5 times per hour; 95% CI 4.1 to 4.9). The highest interruption rate occurred when technologists were in transit between rooms (10.3 per hour (95% CI 8.3 to 12.5)). Interruptions during radiopharmaceutical preparation occurred a mean of 4.4 times per hour (95% CI 3.3 to 5.6). Most (n=426) tasks were interrupted once only and all tasks were resumed after interruption. Multitasking occurred 16.6% of the time. At least some interruptions were initiated by other technologists to convey important information and/or to render assistance. Technologists employed a variety of verbal and non-verbal strategies in all work areas (notably in the hot-lab) to minimise the impact of interruptions and optimise the safe conduct of procedures. Although most were due to individual choices, some strategies reflected overt or subliminal departmental policy. CONCLUSIONS: Some interruptions appear beneficial. Technologists' self-initiated strategies to support safe work practices appear to be an important element in supporting a resilient work environment in nuclear medicine. PMID- 27707871 TI - Sclerotherapy for lymphatic malformations of the head and neck in the pediatric population. AB - BACKGROUND: Sclerotherapy is one of the most commonly used minimally invasive interventions in the treatment of macrocystic lymphatic malformations (LMs). Several different sclerosing agents and injection protocols have been reported in the literature, each with varying degrees of success. The safety and efficacy of the treatments have not been evaluated comparatively in the pediatric population. METHODS: Chart review of pediatric patients with macrocystic/mixed head and neck LMs who underwent sclerotherapy using OK-432, doxycycline, or ethanolamine oleate at Lucile Packard Children's Hospital at Stanford during 2000-2014. Clinical evaluation and radiographic imaging were reviewed to assess lesion characteristics and response to sclerotherapy following each treatment session. The post-intervention clinical response was categorized as excellent, good, fair, or poor. RESULTS: Among the 41 pediatric cases reviewed, 10 patients were treated with OK-432, 19 patients received doxycycline, and 12 patients received ethanolamine. In univariate analysis, different sclerosants had similar effectiveness after the first injection and final clinical outcome (p=0.5317). In multivariate analysis controlling for disease severity stage as well as disease characteristics (macrocystic vs mixed subtypes), different sclerosants also had similar effectiveness after the first injection (p=0.1192). Radiologic analysis indicated an 84.5% average volume reduction, with similar effectiveness between the different sclerosants (p=0.9910). CONCLUSIONS: In this series of LM cases treated at Stanford, we found that doxycycline, OK-432, and ethanolamine oleate sclerotherapy appear to have a similar safety and efficacy profile in the treatment of macrocystic and mixed LMs of the head and neck in the pediatric population. PMID- 27707868 TI - High-resolution metabolomics of occupational exposure to trichloroethylene. AB - BACKGROUND: Occupational exposure to trichloroethylene (TCE) has been linked to adverse health outcomes including non-Hodgkin's lymphoma and kidney and liver cancer; however, TCE's mode of action for development of these diseases in humans is not well understood. METHODS: Non-targeted metabolomics analysis of plasma obtained from 80 TCE-exposed workers [full shift exposure range of 0.4 to 230 parts-per-million of air (ppma)] and 95 matched controls were completed by ultra high resolution mass spectrometry. Biological response to TCE exposure was determined using a metabolome-wide association study (MWAS) framework, with metabolic changes and plasma TCE metabolites evaluated by dose-response and pathway enrichment. Biological perturbations were then linked to immunological, renal and exposure molecular markers measured in the same population. RESULTS: Metabolic features associated with TCE exposure included known TCE metabolites, unidentifiable chlorinated compounds and endogenous metabolites. Exposure resulted in a systemic response in endogenous metabolism, including disruption in purine catabolism and decreases in sulphur amino acid and bile acid biosynthesis pathways. Metabolite associations with TCE exposure included uric acid (beta = 0.13, P-value = 3.6 * 10-5), glutamine (beta = 0.08, P-value = 0.0013), cystine (beta = 0.75, P-value = 0.0022), methylthioadenosine (beta = -1.6, P-value = 0.0043), taurine (beta = -2.4, P-value = 0.0011) and chenodeoxycholic acid (beta = -1.3, P-value = 0.0039), which are consistent with known toxic effects of TCE, including immunosuppression, hepatotoxicity and nephrotoxicity. Correlation with additional exposure markers and physiological endpoints supported known disease associations. CONCLUSIONS: High-resolution metabolomics correlates measured occupational exposure to internal dose and metabolic response, providing insight into molecular mechanisms of exposure-related disease aetiology. PMID- 27707872 TI - In situ tissue engineering: endothelial growth patterns as a function of flow diverter design. AB - BACKGROUND: Vascular remodeling in response to implantation of a tissue engineering scaffold such as a flow diverter (FD) leads to the cure of intracranial aneurysms. We hypothesize that the vascular response is dependent on FD design, and CD34+ progenitor cells play an important role in the endothelialization of the implant. METHODS: Sixteen rabbit aneurysms were randomly treated with two different single-layer braided FDs made of cobalt chrome alloys. The FD-48 and FD-72 devices had 48 and 72 wires, respectively. Aneurysm occlusion rate was assessed during the final digital subtraction angiogram at 10, 20, 30, and 60 days (n=2 per device per time point). Implanted vessels were analyzed with scanning electron microscopy for tissue coverage, endothelialization, and immuno-gold labeling for CD34+ cells. RESULTS: Complete aneurysm occlusion rates were similar between the devices; however, complete or near complete occlusion was more frequently observed in aneurysms with neck <=4.2 mm (p=0.008). Total tissue coverage at 10 days over the surface of the FD-48 and FD-72 devices was 56.4+/-11.6% and 76.6+/-3.6%, respectively. Endothelial cell growth over the surface was time-dependent for the FD-72 device (Spearman's r=0.86, p=0.013) but not for the FD-48 device (Spearman's r=-0.59, p=0.094). The endothelialization score was marginally correlated with the distance from the aneurysm neck for the FD-48 device (Spearman's r=1, p=0.083) but not for the FD 72 device (Spearman's r=0.8, p=0.33). CD34+ cells were present along the entirety of both devices at all time points. CONCLUSIONS: This study gives preliminary evidence that temporal and spatial endothelialization is dependent on FD design. Circulating CD34+ progenitor cells contribute to endothelialization throughout the healing process.

PMID- 27707874 TI - Endovascular isolation of intracranial blood blister-like aneurysms with Willis covered stent. AB - OBJECTIVE: Intracranial blood blister-like aneurysm (BBA) is a rare type of aneurysm that lacks all layers of the arterial wall. These fragile aneurysms have the propensity to rupture with minimal manipulation, which makes them hazardous and difficult to treat. The present study evaluated the safety and feasibility of endovascular treatment of BBAs with the Willis covered stent. MATERIALS: Thirteen patients (7 men and 6 women, age range 28-68 years) who presented with ruptured BBAs and were treated with the Willis covered stent were retrospectively reviewed. Results of the procedures and treatment-related complications were recorded. Angiographic and clinical follow-ups were performed 4-6 months after the procedure. RESULTS: Placement of the covered stent was successful in all patients. Immediate angiography showed complete aneurysm occlusion in 12 patients while one patient showed a mild endoleak. This high rate of aneurysm exclusion ensured the security of postoperative antiplatelet treatment. Occlusion of the ophthalmic artery occurred in two patients and occlusion of the anterior choroidal artery occurred in one patient; however, none of them showed acute or delayed clinical symptoms. Thrombosis, aneurysm rupture, and other complications did not develop in any case. Angiographic follow-up showed complete aneurysm exclusion without aneurysm recurrence in any patients. Only two patients showed asymptomatic mild to moderate in-stent stenosis. All patients had satisfactory clinical outcomes (modified Rankin Scale score <=1). CONCLUSIONS: Willis covered stent implementation may be safe and feasible for BBAs. This strategy might be a promising option for this high-risk type of aneurysm. PMID- 27707875 TI - Respect for autonomy: deciding what is good for oneself. AB - Paternalistic interference in autonomous decisions is typically impermissible. This has several explanations, among which is a view I call the agent constitution of the good: that the autonomous agent not only knows what is best for herself, but determines what is best for herself through her desires, goals and so on (her aims). For instance, it might seem that if an autonomous person does choose not to take insulin for her diabetes, then not only is it inappropriate to force treatment upon her, it is also not in her best interest to take insulin. Here I argue that agent-constitution, though appealing, is false. In fact, autonomous agents can be mistaken about their good, even when it seems to depend only upon their aims. Agent-constitution appears true only because we typically fail to notice constraints on a person's good in private, self regarding decisions where paternalism might be considered. PMID- 27707876 TI - Is it objectionable to create a child as a carer for a disabled parent? AB - In his recent paper, Adam Cureton presents a compelling case in support of the right of parents with disabilities to conceive and raise children. Cureton argues that (a) caring for a parent with a disability may be beneficial for a child and (b) the creation of a child with the intention of him/her being a carer for his/her disabled parent is objectionable. This response to Cureton's paper will focus on the creation of children with the purpose of them being carers for their disabled parents. I will respond to Cureton on three counts. First, I propose that claims (a) and (b) are incompatible. Second, I will argue that even from a Kantian perspective it is not clear that creating a child as a carer is objectionable. Third, I will argue more broadly that the intentions with which parents bring children into the world are not predictive of the concern parents should show their children once they come into existence. PMID- 27707877 TI - Which strings attached: ethical considerations for selecting appropriate conditionalities in conditional cash transfer programmes. AB - Conditional cash transfers (CCTs) present a promising approach to simultaneously tackle chronic poverty and poor health. While these programmes clearly embody beneficent aims, questions remain regarding the ethical design of CCTs. Limited guidance exists for the ethical evaluation of the defining feature of these programmes: the conditionalities. Drawing upon prominent public health ethics frameworks and social justice theories, this paper outlines five categories of morally relevant considerations that CCT programme designers should consider when assessing which behaviours or outcomes they select as conditionalities for payment: (1) likelihood of yielding desired health outcomes, (2) risks and burdens, (3) receptivity, (4) attainability and (5) indirect impacts and externalities. When evaluating potential conditionalities across these five categories of considerations, it is important to recognise that not all beneficiaries or subgroups of beneficiaries will fare equally on each. Given that most CCTs aim to reduce inequities and promote long-term health and prosperity for the most disadvantaged, it is critical to apply these considerations with due attention to how different segments of the beneficiary population will be differentially affected. Taken on balance, with due reflection on distributional effects, these five categories represent a comprehensive set of considerations for the moral analysis of specific conditionalities and will help ensure that CCT designers structure programmes in a way that is both morally sound and effective in achieving their goals. PMID- 27707878 TI - Incentives, equity and the Able Chooser Problem. AB - Health incentive schemes aim to produce healthier behaviours in target populations. They may do so both by making incentivised options more salient and by making them less costly. Changes in costs only result in healthier behaviour if the individual rationally assesses the cost change and acts accordingly. Not all people do this well. Those who fail to respond rationally to incentives will typically include those who are least able to make prudent choices more generally. This group will typically include the least advantaged more generally, since disadvantage inhibits one's effective ability to choose well and since poor choices tend to cause or aggravate disadvantage. Therefore, within the target population, health benefits to the better off may come at the cost of aggravated inequity. This is one instance of a problem I name the Able Chooser Problem, previously emphasised by Richard Arneson in relation to coercive paternalism. I describe and discuss this problem by distinguishing between policy options and their effects on the choice situation of individuals. Both positive and negative incentives, as well as mandates that are less than perfectly effective, require some sort of rational deliberation and action and so face the Able Chooser Problem. In contrast, effective restriction of what options are physically available, as well as choice context design that makes some options more salient or appealing, does not demand rational agency. These considerations provide an equity-based argument for preferring smart design of our choice and living environment to incentives and mandates. PMID- 27707879 TI - MAGI-1 Interacts with Nephrin to Maintain Slit Diaphragm Structure through Enhanced Rap1 Activation in Podocytes. AB - MAGI-1 is a multidomain cytosolic scaffolding protein that in the kidney is specifically located at the podocyte slit diaphragm, a specialized junction that is universally injured in proteinuric diseases. There it interacts with several essential molecules, including nephrin and neph1, which are required for slit diaphragm formation and as an intracellular signaling hub. Here, we show that diminished MAGI-1 expression in cultured podocytes reduced nephrin and neph1 membrane localization and weakened tight junction integrity. Global magi1 knock out mice, however, demonstrated normal glomerular histology and function into adulthood. We hypothesized that a second mild but complementary genetic insult might induce glomerular disease susceptibility in these mice. To identify such a gene, we utilized the developing fly eye to test for functional complementation between MAGI and its binding partners. In this way, we identified diminished expression of fly Hibris (nephrin) or Roughest (neph1) as dramatically exacerbating the effects of MAGI depletion. Indeed, when these combinations were studied in mice, the addition of nephrin, but not neph1, heterozygosity to homozygous deletion of MAGI-1 resulted in spontaneous glomerulosclerosis. In cultured podocytes, MAGI-1 depletion reduced intercellular contact-induced Rap1 activation, a pathway critical for proper podocyte function. Similarly, magi1 knock-out mice showed diminished glomerular Rap1 activation, an effect dramatically enhanced by concomitant nephrin haploinsufficiency. Finally, combined overexpression of MAGI-1 and nephrin increased Rap1 activation, but not when substituting a mutant MAGI-1 that cannot bind nephrin. We conclude that the interaction between nephrin and MAGI-1 regulates Rap1 activation in podocytes to maintain long term slit diaphragm structure.

AB - The severity of influenza A virus (IAV) infection can range from asymptotic to mild to severe. Infections, such as those seen following outbreaks of avian IAV, are associated with hyperinflammatory responses and the development of fatal disease. There is a continual threat that a novel or pandemic IAV will circulate in humans with high rates of mortality. The neuronal apoptosis inhibitor protein, class 2 transcription activator of the MHC, heterokaryon incompatibility, telomerase-associated protein 1, leucine-rich repeat, and pyrin domain-containing protein 3 (NLRP3) inflammasome is an innate immune sensor that has been shown to be critical for the secretion of the potent proinflammatory cytokines, IL-1beta and IL-18, as well as chemokine production and cellular inflammation in vivo following IAV infection. Initial studies illustrated a protective role of NLRP3 during severe IAV infection in mice. However, the NLRP3 inflammasome may be a hero that turns villain in the later stages of severe IAV infection via the promotion of a hyperinflammatory state. Current treatments for patients who present to hospitals with a severe IAV infection are limited. The understanding of the mechanisms involved in the induction of NLRP3-dependent inflammation during severe IAV infections may provide new therapeutic targets that reduce human mortality. PMID- 27707880 TI - Pre-T Cell Receptors (Pre-TCRs) Leverage Vbeta Complementarity Determining Regions (CDRs) and Hydrophobic Patch in Mechanosensing Thymic Self-ligands. AB - The pre-T cell receptor (pre-TCR) is a pTalpha-beta heterodimer functioning in early alphabeta T cell development. Although once thought to be ligand autonomous, recent studies show that pre-TCRs participate in thymic repertoire formation through recognition of peptides bound to major histocompatibility molecules (pMHC). Using optical tweezers, we probe pre-TCR bonding with pMHC at the single molecule level. Like the alphabetaTCR, the pre-TCR is a mechanosensor undergoing force-based structural transitions that dynamically enhance bond lifetimes and exploiting allosteric control regulated via the Cbeta FG loop region. The pre-TCR structural transitions exhibit greater reversibility than TCRalphabeta and ordered force-bond lifetime curves. Higher piconewton force requires binding through both complementarity determining region loops and hydrophobic Vbeta patch apposition. This patch functions in the pre-TCR as a surrogate Valpha domain, fostering ligand promiscuity to favor development of beta chains with self-reactivity but is occluded by alpha subunit replacement of pTalpha upon alphabetaTCR formation. At the double negative 3 thymocyte stage where the pre-TCR is first expressed, pre-TCR interaction with self-pMHC ligands imparts growth and survival advantages as revealed in thymic stromal cultures, imprinting fundamental self-reactivity in the T cell repertoire. Collectively, our data imply the existence of sequential mechanosensor alphabetaTCR repertoire tuning via the pre-TCR. PMID- 27707883 TI - Protein kinase CK2 controls T-cell polarization through dendritic cell activation in response to contact sensitizers. AB - Allergic contact dermatitis (ACD) represents a severe health problem with increasing worldwide prevalence. It is a T-cell-mediated inflammatory skin disease caused by chemicals present in the daily or professional environment. NiSO4 and 2,4-dinitrochlorobenzene (DNCB) are 2 chemicals involved in ACD. These contact sensitizers are known to induce an up-regulation of phenotypic markers and cytokine secretion in dendritic cells (DCs; professional APCs), leading to the generation of CD8+ Tc1/Tc17 and CD4+ Th1/Th17 effector T cells. In the present study, using a peptide array approach, we identified protein kinase CK2 as a novel kinase involved in the activation of human monocyte-derived DCs (MoDCs) in response to NiSO4 and DNCB. Inhibition of CK2 activity in MoDCs led to an altered mature phenotype with lower expression of CD54, PDL-1, CD86, and CD40 in response to NiSO4 or DNCB. CK2 activity also regulated proinflammatory cytokine production, such as TNF-alpha, IL-1beta, and IL-23 in MoDCs. Moreover, in a DC/T cell coculture model in an allogeneic setup, CK2 activity in MoDCs played a major role in Th1 polarization in response to NiSO4 and DNCB. CK2 inhibition in MoDCs led to an enhanced Th2 polarization in the absence of contact sensitizer stimulation. PMID- 27707882 TI - IFN-gamma targets macrophage-mediated immune responses toward Staphylococcus aureus. AB - Infections, especially with Staphylococcus aureus (SA), commonly cause morbidity and mortality in patients with chronic granulomatous disease (CGD), a condition characterized by a defective phagocyte oxidase. IFN-gamma reduces the frequency and consequences of infection in CGD by mechanisms that remain unknown. As IFN gamma promotes bacterial killing, efferocytosis of effete polymorphonuclear neutrophils (PMN), and cytokine production in macrophages-the same macrophage effector functions that are impaired in response to SA-we hypothesized that IFN gamma may reverse these defects and thereby, augment macrophage control of SA during infection. IFN-gamma primed activation of the NADPH oxidase in a time dependent manner, enhanced killing of ingested SA independent of any effects on phagocytosis, and increased binding of SA-laden neutrophils (PMN-SA) to macrophages. However, IFN-gamma did not increase the percentage of apoptotic PMN or PMN-SA internalized by macrophages. Under conditions in which viable SA were eliminated, PMN-SA primed the inflammasome for subsequent activation by silica but did not induce IL-1beta production by macrophages. IFN-gamma enhanced IL-6 production in response to SA or PMN-SA but did not increase inflammasome activation in response to either agonist. In summary, IFN-gamma augmented direct killing of SA by macrophages, promoted engagement of PMN-SA, and enhanced macrophage-mediated cytokine responses that could collectively augment control of SA infection. Together, these findings support the hypothesis that IFN-gamma improves responsiveness of macrophages to SA and provides insights into the mechanism of the clinical benefits of IFN-gamma. PMID- 27707884 TI - Ikaros 6 protects acute lymphoblastic leukemia cells against daunorubicin-induced apoptosis by activating the Akt-FoxO1 pathway. AB - Ikaros isoform 6 (Ik6) is associated with a poor prognosis for children with acute lymphoblastic leukemia (ALL). Our previous study demonstrated that overexpression of Ik6 enhances proliferation and chemoresistance of leukemia cells, with a possible underlying mechanism that involves antiapoptosis. In the present study, we investigated whether Ik6 protects against apoptosis by regulating the Akt-FoxO1 pathway. Bone marrow samples from children with ALL were collected and evaluated. In Ik6+ patients, the Akt-FoxO1 pathway was activated such that expression of phosphorylated Akt and FoxO1 was significantly increased, but that of Bim and p27 decreased. In vitro experiments in this study were performed by using human ALL Nalm-6 cells that were stably transfected with Ik6 (Nalm-6/Ik6) or Sup-B15 and Ik6 shRNA (Sup-B15/Ik6 shRNA). Upon treatment with daunorubicin, Nalm-6/Ik6 cells exhibited a statistically significant reduction in apoptosis, with increased expression of p-Akt and p-FoxO1. In contrast, an increase in apoptosis with decreased expression of p-Akt and p-FoxO1 was observed in Sup-B15/Ik6 shRNA cells. This protection was dependent on activation of caspase-3 cleavage. By using an activator and an inhibitor of Akt or FoxO1, we demonstrated that Akt or FoxO1 activation had no effect on Ik6 expression. In conclusion, Ik6, the upstream factor of Akt-FoxO1 pathway, can protect ALL cells against daunorubicin-induced apoptosis and can potentially be explored as a therapeutic target in the treatment of patients with ALL. PMID- 27707885 TI - Financial Strain, Parental Smoking, and the Great Recession: An Analysis of the UK Millennium Cohort Study. AB - Introduction: During the recent "Great Recession," many families in the United Kingdom experienced increased financial strain (FS). The aim of this study was to determine if increases in FS, occurring over the period of the "Great Recession," were associated with increased risks of persistent and relapsed tobacco use among parents. Methods: We analyzed the Millennium Cohort Study, a longitudinal study of 18819 children born in the United Kingdom between 2000 and 2002. Surveys at 7 (T1, 2008) and 11 years (T2, 2012) spanned the "Great Recession." Three measures of increased FS were defined; "became income poor" (self-reported household income dropped below the "poverty line" between T1 and T2); "developed difficulty managing" (parental report of being "financially comfortable" at T1 and finding it "difficult to manage" at T2); "felt worse off" (parental report of feeling financially "worse off" at T2, compared to T1). Poisson regression was used to estimate risk ratios (RR), adjusted RRs (aRR), and 95% confidence intervals for three outcomes: "persistent tobacco use," "new reported tobacco use," and "relapsed tobacco use." Results: Parents in households which "became income poor" over the period of the "Great Recession" were significantly more likely to report "persistent tobacco use" (aRR = 2.17 [1.83-2.57]) or "new reported tobacco use" (aRR = 1.72 [1.04-2.83]). Ninety-five percent of "new reported tobacco users" had evidence of prior tobacco use suggesting the majority were "relapsed tobacco users." Similar patterns were seen for those who "developed difficulty managing" and "felt worse off." Conclusions: Increased tobacco use among financially strained families has the potential to widen inequalities and undermine the public health policies that have had positive impacts on tobacco consumption in the United Kingdom. Implications: While several studies have shown that FS is associated with a higher prevalence of tobacco use, heavier smoking, and relapsed tobacco use, most of this work used cross-sectional data and none has focused on parents. We used longitudinal data from the UK Millennium Cohort Study, between 2008 and 2012, to examine the association between FS and parental smoking. We show that parents who experienced increased FS, over the period of the "Great Recession," were more likely to continue using tobacco or to relapse. PMID- 27707886 TI - Exploitation of Castration-Resistant Prostate Cancer Transcription Factor Dependencies by the Novel BET Inhibitor ABBV-075. AB - : Competitive inhibitors of acetyl-lysine binding to the bromodomains of the BET (bromodomain and extra terminal) family are being developed for the treatment of solid and hematologic malignancies. The function of BET family member BRD4 at enhancers/superenhancers has been shown to sustain signal-dependent or pathogenic gene expression programs. Here, the hypothesis was tested that the transcription factor drivers of castration-resistant prostate cancer (CRPC) clinical progression, including the androgen receptor (AR), are critically dependent on BRD4 and thus represent a sensitive solid tumor indication for the BET inhibitor ABBV-075. DHT-stimulated transcription of AR target genes was inhibited by ABBV 075 without significant effect on AR protein expression. Furthermore, ABBV-075 disrupted DHT-stimulated recruitment of BET family member BRD4 to gene-regulatory regions cooccupied by AR, including the well-established PSA and TMPRSS2 enhancers. Persistent BET inhibition disrupted the composition and function of AR occupied enhancers as measured by a reduction in AR and H3K27Ac ChIP signal and inhibition of enhancer RNA transcription. ABBV-075 displayed potent antiproliferative activity in multiple models of resistance to second-generation antiandrogens and inhibited the activity of the AR splice variant AR-V7 and ligand-binding domain gain-of-function mutations, F877L and L702H. ABBV-075 was also a potent inhibitor of MYC and the TMPRSS2-ETS fusion protein, important parallel transcription factor drivers of CRPC. IMPLICATIONS: The ability of BET family inhibitor ABBV-075 to inhibit transcription activation downstream of the initiating events of transcription factors like AR and TMPRSS2:ETS fusion proteins provides a promising therapeutic option for CRPC patients who have developed resistance to second-generation antiandrogens.

AB - : Activation of the EGFR pathway is one of the mechanisms inducing acquired resistance to anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKI) such as crizotinib and alectinib. Ceritinib is a highly selective ALK inhibitor and shows promising efficacy in non-small cell lung cancers (NSCLC) harboring the ALK gene rearrangement. However, the precise mechanism underlying acquired resistance to ceritinib is not well-defined. This study set out to clarify the mechanism in ALK-translocated lung cancer and to find the preclinical rationale overcoming EGFR pathway-induced acquired resistance to ALK-TKIs. To this end, ceritinib-resistant cells (H3122-CER) were established from the H3122 NSCLC cell line harboring the ALK gene rearrangement via long-term exposure to ceritinib. H3122-CER cells acquired resistance to ceritinib through EGFR bypass pathway activation. Furthermore, H3122 cells that became resistant to ceritinib or alectinib through EGFR pathway activation showed cross-resistance to other ALK TKIs. Ceritinib and afatinib combination treatment partially restored the sensitivity to ceritinib. IMPLICATIONS: This study proposes a preclinical rationale to use ALK-TKIs and afatinib combination therapy for ALK-translocated lung cancers that have acquired resistance to ALK-TKIs through EGFR pathway activation.

AB - Natural accessions of Arabidopsis (Arabidopsis thaliana) differ in their ability to tolerate a loss of chloroplast translation. These differences can be attributed in part to variation in a duplicated nuclear gene (ACC2) that targets homomeric acetyl-coenzyme A carboxylase (ACCase) to plastids. This functional redundancy allows limited fatty acid biosynthesis to occur in the absence of heteromeric ACCase, which is encoded in part by the plastid genome. In the presence of functional ACC2, tolerant alleles of several nuclear genes, not yet identified, enhance the growth of seedlings and embryos disrupted in chloroplast translation. ACC2 knockout mutants, by contrast, are hypersensitive. Here we describe an expanded search for hypersensitive accessions of Arabidopsis, evaluate whether all of these accessions are defective in ACC2, and characterize genotype-to-phenotype relationships for homomeric ACCase variants identified among 855 accessions with sequenced genomes. Null alleles with ACC2 nonsense mutations, frameshift mutations, small deletions, genomic rearrangements, and defects in RNA splicing are included among the most sensitive accessions examined. By contrast, most missense mutations affecting highly conserved residues failed to eliminate ACC2 function. Several accessions were identified where sensitivity could not be attributed to a defect in either ACC2 or Tic20-IV, the chloroplast membrane channel required for ACC2 uptake. Overall, these results underscore the central role of ACC2 in mediating Arabidopsis response to a loss of chloroplast translation, highlight future applications of this system to analyzing chloroplast protein import, and provide valuable insights into the mutational landscape of an important metabolic enzyme that is highly conserved throughout eukaryotes. PMID- 27707891 TI - Employing imaginative rationality: using metaphor when discussing death. AB - The prevalence of metaphors in medicine is widely acknowledged. In a qualitative study exploring expectations of longevity, we observed repeated recourse to the imaginative rationality provided by metaphors to express perspectives on longevity and death. Bafflement, acceptance, uncertainty and distress were conveyed through metaphors, providing valuable insight into the internal healthcare frameworks of participants. Skilful use of imaginative rationality in the healthcare setting may illuminate the elusive and often eschewed topic of death in a way that fosters clarity and new understandings, and pave the way towards a better life, and death for patients. By becoming aware of the nuances contained within patients'-as well as their own-metaphors, clinicians may enhance patients' overall healthcare experience and avert unintended miscommunication. PMID- 27707890 TI - A Single Arabidopsis Gene Encodes Two Differentially Targeted Geranylgeranyl Diphosphate Synthase Isoforms. AB - A wide diversity of isoprenoids is produced in different plant compartments. Most groups of isoprenoids synthesized in plastids, and some produced elsewhere in the plant cell derive from geranylgeranyl diphosphate (GGPP) synthesized by GGPP synthase (GGPPS) enzymes. In Arabidopsis (Arabidopsis thaliana), five genes appear to encode GGPPS isoforms localized in plastids (two), the endoplasmic reticulum (two), and mitochondria (one). However, the loss of function of the plastid-targeted GGPPS11 isoform (referred to as G11) is sufficient to cause lethality. Here, we show that the absence of a strong transcription initiation site in the G11 gene results in the production of transcripts of different lengths. The longer transcripts encode an isoform with a functional plastid import sequence that produces GGPP for the major groups of photosynthesis-related plastidial isoprenoids. However, shorter transcripts are also produced that lack the first translation initiation codon and rely on a second in-frame ATG codon to produce an enzymatically active isoform lacking this N-terminal domain. This short enzyme localizes in the cytosol and is essential for embryo development. Our results confirm that the production of differentially targeted enzyme isoforms from the same gene is a central mechanism to control the biosynthesis of isoprenoid precursors in different plant cell compartments. PMID- 27707888 TI - Hydrocarbons Are Essential for Optimal Cell Size, Division, and Growth of Cyanobacteria. AB - Cyanobacteria are intricately organized, incorporating an array of internal thylakoid membranes, the site of photosynthesis, into cells no larger than other bacteria. They also synthesize C15-C19 alkanes and alkenes, which results in substantial production of hydrocarbons in the environment. All sequenced cyanobacteria encode hydrocarbon biosynthesis pathways, suggesting an important, undefined physiological role for these compounds. Here, we demonstrate that hydrocarbon-deficient mutants of Synechococcus sp. PCC 7002 and Synechocystis sp. PCC 6803 exhibit significant phenotypic differences from wild type, including enlarged cell size, reduced growth, and increased division defects. Photosynthetic rates were similar between strains, although a minor reduction in energy transfer between the soluble light harvesting phycobilisome complex and membrane-bound photosystems was observed. Hydrocarbons were shown to accumulate in thylakoid and cytoplasmic membranes. Modeling of membranes suggests these compounds aggregate in the center of the lipid bilayer, potentially promoting membrane flexibility and facilitating curvature. In vivo measurements confirmed that Synechococcus sp. PCC 7002 mutants lacking hydrocarbons exhibit reduced thylakoid membrane curvature compared to wild type. We propose that hydrocarbons may have a role in inducing the flexibility in membranes required for optimal cell division, size, and growth, and efficient association of soluble and membrane bound proteins. The recent identification of C15-C17 alkanes and alkenes in microalgal species suggests hydrocarbons may serve a similar function in a broad range of photosynthetic organisms. PMID- 27707892 TI - Laboratory Response to 2014 Ebola Virus Outbreak in Mali. AB - Aware of the rapid spread of Ebola virus (EBOV) during the current West African epidemic, Mali took several proactive steps to rapidly identify cases within its borders. Under the Mali International Center for Excellence in Research program, a collaboration between the National Institute of Allergy and Infectious Diseases and the Malian Ministry of Higher Education and Scientific Research established a national EBOV diagnostic site at the University of Sciences, Techniques and Technologies of Bamako in the SEREFO Laboratory. Two separate introductions of EBOV occurred in Mali from neighboring Guinea, but both chains of transmission were quickly halted, and Mali was declared "Ebola free" on 18 January 2015 and has remained so since. The SEREFO Laboratory was instrumental in the success of Mali's Ebola response by providing timely and accurate diagnostics. As of today, the SEREFO Laboratory has tested 103 samples from 88 suspected cases, 10 of which were EBOV positive, since the Ebola diagnostics unit started in April 2014. The establishment of Ebola diagnostics in the SEREFO Laboratory, safety precautions, and diagnostics are described. PMID- 27707893 TI - More Challenges From Ebola: Infection of the Central Nervous System. AB - Cases of relapsed Ebola virus disease involving symptoms in the central nervous system are reminiscent of our past observations with some nonhuman primates (NHPs) that survived acute Ebola virus infection. We document our findings in detail here and suggest that this phenomenon can be further investigated in NHPs. PMID- 27707894 TI - Neocortex expansion is linked to size variations in gene families with chemotaxis, cell-cell signalling and immune response functions in mammals. AB - Increased brain size is thought to have played an important role in the evolution of mammals and is a highly variable trait across lineages. Variations in brain size are closely linked to corresponding variations in the size of the neocortex, a distinct mammalian evolutionary innovation. The genomic features that explain and/or accompany variations in the relative size of the neocortex remain unknown. By comparing the genomes of 28 mammalian species, we show that neocortical expansion relative to the rest of the brain is associated with variations in gene family size (GFS) of gene families that are significantly enriched in biological functions associated with chemotaxis, cell-cell signalling and immune response. Importantly, we find that previously reported GFS variations associated with increased brain size are largely accounted for by the stronger link between neocortex expansion and variations in the size of gene families. Moreover, genes within these families are more prominently expressed in the human neocortex during early compared with adult development. These results suggest that changes in GFS underlie morphological adaptations during brain evolution in mammalian lineages. PMID- 27707895 TI - Streptococcal group B integrative and mobilizable element IMESag-rpsI encodes a functional relaxase involved in its transfer. AB - Streptococcus agalactiae or Group B Streptococcus (GBS) are opportunistic bacteria that can cause lethal sepsis in children and immuno-compromised patients. Their genome is a reservoir of mobile genetic elements that can be horizontally transferred. Among them, integrative and conjugative elements (ICEs) and the smaller integrative and mobilizable elements (IMEs) primarily reside in the bacterial chromosome, yet have the ability to be transferred between cells by conjugation. ICEs and IMEs are therefore a source of genetic variability that participates in the spread of antibiotic resistance. Although IMEs seem to be the most prevalent class of elements transferable by conjugation, they are poorly known. Here, we have studied a GBS-IME, termed IMESag-rpsI, which is widely distributed in GBS despite not carrying any apparent virulence trait. Analyses of 240 whole genomes showed that IMESag-rpsI is present in approximately 47% of the genomes, has a roughly constant size (approx. 9 kb) and is always integrated at a single location, the 3'-end of the gene encoding the ribosomal protein S9 (rpsI). Based on their genetic variation, several IMESag-rpsI types were defined (A-J) and classified in clonal complexes (CCs). CC1 was the most populated by IMESag rpsI (more than 95%), mostly of type-A (71%). One CC1 strain (S. agalactiae HRC) was deep-sequenced to understand the rationale underlying type-A IMESag-rpsI enrichment in GBS. Thirteen open reading frames were identified, one of them encoding a protein (MobSag) belonging to the broadly distributed family of relaxases MOBV1 Protein MobSag was purified and, by a newly developed method, shown to cleave DNA at a specific dinucleotide. The S. agalactiae HRC-IMESag-rpsI is able to excise from the chromosome, as shown by the presence of circular intermediates, and it harbours a fully functional mobilization module. Further, the mobSag gene encoded by this mobile element is able to promote plasmid transfer among pneumococcal strains, suggesting that MobSag facilitates the spread of IMESag-rpsI and that this spread would explain the presence of the same IMESag-rpsI type in GBS strains belonging to different CCs. PMID- 27707896 TI - Health-related behaviours and mental health in Hong Kong employees. AB - BACKGROUND: Poor physical and mental health in employees can result in a serious loss of productivity. Early detection and management of unhealthy behaviours and mental health symptoms can prevent productivity loss and foster healthy workplaces. AIMS: To examine health-related behaviours, mental health status and help-seeking patterns in employees, across different industries in Hong Kong. METHODS: Participants were telephone-interviewed and assessed using the Case finding and Help Assessment Tool (CHAT) with employee lifestyle risk factors, mental health issues and help-seeking intentions screened across eight industries. Subsequent data analysis involved descriptive statistics and chi square tests. RESULTS: There were 1031 participants. Key stressors were work (30%), family (19%), money (14%) and interpersonal issues (5%). Approximately 18, 9 and 9% of participants were smokers, drinkers and gamblers, respectively, and only 51% exercised regularly. Depressive and anxiety symptoms were reported by 24 and 31% of employees, respectively. Issues for which they wanted immediate help were interpersonal abuse (16%), anxiety (15%), anger control (14%) and depression (14%). Employees with higher educational attainment were less likely to smoke, drink and gamble than those with lower attainment. Lifestyle and mental health status were not associated with income. Employees in construction and hotel industries smoked more and those in manufacturing drank more than those in other industries. CONCLUSIONS: Physical and mental health of Hong Kong employees are concerning. Although employee assistance programmes are common among large companies, initiation of proactive engagement approaches, reaching out to those employees in need and unlikely to seek help for mental health issues, may be useful. PMID- 27707897 TI - Are inspectors' assessments reliable? Ratings of NHS acute hospital trust services in England. AB - The credibility of a regulator could be threatened if stakeholders perceive that assessments of performance made by its inspectors are unreliable. Yet there is little published research on the reliability of inspectors' assessments of health care organizations' services. Objectives We investigated the inter-rater reliability of assessments made by inspectors inspecting acute hospitals in England during the piloting of a new regulatory model implemented by the Care Quality Commission (CQC) during 2013 and 2014. Multi-professional teams of inspectors rated service provision on a four-point scale for each of five domains: safety; effectiveness; caring; responsiveness; and leadership. Methods In an online survey, we asked individual inspectors to assign a domain and a rating to each of 10 vignettes of service information extracted from CQC inspection reports. We used these data to simulate the ratings that might be produced by teams of inspectors. We also observed inspection teams in action, and interviewed inspectors and staff from hospitals that had been inspected. Results Levels of agreement varied substantially from vignette to vignette. Characteristics such as professional background explained only a very small part of the variation. Overall, agreement was higher on ratings than on domains, and for groups of inspectors compared with individual inspectors. A number of potential causes of disagreement were identified, such as differences regarding the weight that should be given to contextual factors and general uncertainty about interpreting the rating and domain categories. Conclusion Groups of inspectors produced more reliable assessments than individual inspectors, and there is evidence to support the utility of appropriate discussions between inspectors in improving reliability. The reliability of domain allocations was lower than for ratings. It is important to define categories and rating levels clearly, and to train inspectors in their use. Further research is needed to replicate these results now that the model has been fully implemented, and to understand better the impact that inspector uncertainty and disagreement may have on published CQC ratings. PMID- 27707899 TI - Small-Molecule Disruption of the Myb/p300 Cooperation Targets Acute Myeloid Leukemia Cells. AB - The transcription factor c-Myb is essential for the proliferation of hematopoietic cells and has been implicated in the development of leukemia and other human cancers. Pharmacologic inhibition of Myb is therefore emerging as a potential therapeutic strategy for these diseases. By using a Myb reporter cell line, we have identified plumbagin and several naphthoquinones as potent low molecular weight Myb inhibitors. We demonstrate that these compounds inhibit c Myb by binding to the c-Myb transactivation domain and disrupting the cooperation of c-Myb with the coactivator p300, a major driver of Myb activity. Naphthoquinone-induced inhibition of c-Myb suppresses Myb target gene expression and induces the differentiation of the myeloid leukemia cell line HL60. We demonstrate that murine and human primary acute myeloid leukemia cells are more sensitive to naphthoquinone-induced inhibition of clonogenic proliferation than normal hematopoietic progenitor cells. Overall, our work demonstrates for the first time the potential of naphthoquinones as small-molecule Myb inhibitors that may have therapeutic potential for the treatment of leukemia and other tumors driven by deregulated Myb.

AB - We conducted a cross-sectional study to evaluate timeliness of patient arrival at a pediatric multispecialty clinic. Bivariate and ordered logistic regression analyses were conducted to determine the odds of late arrival by specified patient- and visit-level characteristics. A total of 64 856 visits were available for analysis, of which 6513 (10.0%) were late arrivals. The odds of late arrival were higher for patients who spoke English (odds ratio [OR] = 1.34, P < .001) compared with those who spoke Spanish, had Medicaid (OR = 1.54, P < .001) or no insurance (OR = 1.49, P < .001) compared with those with insurance other than Medicaid, and were late to their previous visit (OR = 2.46, P < .001). Visit level variables associated with late arrival included appointment time earlier in the day (i.e. 8-10 am, OR = 2.77, P < .001 compared with 4-6 pm), earlier in the week (i.e. on Mondays, OR = 1.21, P < .001 compared with Wednesdays), and for certain subspecialty clinics ( P < .001). Numerous variables are significantly associated with late arrival for pediatric clinic appointments.

We obtained 128 responses: 73 electronically (57%) and 55 via the paper survey (43%). Forty-five percent reported personally using complementary and alternative medicine and 9% of women respondents used complementary and alternative medicine during pregnancy. Overall, 62% had advised their patients to utilize some form of complementary and alternative medicine in pregnancy. Biofeedback, massage therapy, meditation, and yoga were considered the most effective modalities in pregnancy (median [semi interquartile range] = 2 [0.5]). Maternal-fetal medicine specialists were significantly more likely to disagree on the use of complementary and alternative medicine for risk reduction of preterm birth compared to obstetricians and gynecologists ( P = .03). As the use of complementary and alternative medicine continues to rise in reproductive-age women, obstetricians will play an integral role in incorporating complementary and alternative medicine use with conventional medicine. PMID- 27707902 TI - The Significance of Ayurvedic Medicinal Plants. AB - Traditional Indian medicine (ayurveda) is becoming increasingly popular, with many chronic conditions responding to it well. Most patients begin to take conventional medications as soon as their diagnoses are made, so ayurvedic treatments are usually undergone alongside and/or after conventional medical approaches. A detailed knowledge of the action of food, spices, and medicinal plants is needed in order to understand their potential influence fully. While societal use of ayurvedic plants and Indian spices is commonplace, without ill effect, the use of more concentrated products made from single plants, often in the form of teas or tablets, is of more concern. The mechanisms by which polyherbal drugs and their extracts act differ in many respects from the actions of single substances or synthetic drugs. Despite the fact that ayurvedic medicines are based on natural herbal materials, their safety depends on their method of administration, taking into account individuals' needs and their specific disease conditions. PMID- 27707903 TI - Fruit fly scale robots can hover longer with flapping wings than with spinning wings. AB - Hovering flies generate exceptionally high lift, because their wings generate a stable leading edge vortex. Micro flying robots with a similar wing design can generate similar high lift by either flapping or spinning their wings. While it requires less power to spin a wing, the overall efficiency depends also on the actuator system driving the wing. Here, we present the first holistic analysis to calculate how long a fly-inspired micro robot can hover with flapping versus spinning wings across scales. We integrate aerodynamic data with data-driven scaling laws for actuator, electronics and mechanism performance from fruit fly to hummingbird scales. Our analysis finds that spinning wings driven by rotary actuators are superior for robots with wingspans similar to hummingbirds, yet flapping wings driven by oscillatory actuators are superior at fruit fly scale. This crossover is driven by the reduction in performance of rotary compared with oscillatory actuators at smaller scale. Our calculations emphasize that a systems level analysis is essential for trading-off flapping versus spinning wings for micro flying robots. PMID- 27707904 TI - The role of amino acids in hydroxyapatite mineralization. AB - Polar and charged amino acids (AAs) are heavily expressed in non-collagenous proteins (NCPs), and are involved in hydroxyapatite (HA) mineralization in bone. Here, we review what is known on the effect of single AAs on HA precipitation. Negatively charged AAs, such as aspartic acid, glutamic acid (Glu) and phosphoserine are largely expressed in NCPs and play a critical role in controlling HA nucleation and growth. Positively charged ones such as arginine (Arg) or lysine (Lys) are heavily involved in HA nucleation within extracellular matrix proteins such as collagen. Glu, Arg and Lys intake can also increase bone mineral density by stimulating growth hormone production. In vitro studies suggest that the role of AAs in controlling HA precipitation is affected by their mobility. While dissolved AAs are able to inhibit HA precipitation and growth by chelating Ca2+ and PO43- ions or binding to nuclei of calcium phosphate and preventing their further growth, AAs bound to surfaces can promote HA precipitation by attracting Ca2+ and PO43- ions and increasing the local supersaturation. Overall, the effect of AAs on HA precipitation is worth being investigated more, especially under conditions closer to the physiological ones, where the presence of other factors such as collagen, mineralization inhibitors, and cells heavily influences HA precipitation. A deeper understanding of the role of AAs in HA mineralization will increase our fundamental knowledge related to bone formation, and could lead to new therapies to improve bone regeneration in damaged tissues or cure pathological diseases caused by excessive mineralization in tissues such as cartilage, blood vessels and cardiac valves. PMID- 27707905 TI - Role of intracellular poroelasticity on freezing-induced deformation of cells in engineered tissues. AB - Freezing of biomaterials is important in a wide variety of biomedical applications, including cryopreservation and cryosurgeries. For the success of these applications to various biomaterials, biophysical mechanisms, which determine freezing-induced changes in cells and tissues, need to be well understood. Specifically, the significance of the intracellular mechanics during freezing is not well understood. Thus, we hypothesize that cells interact during freezing with the surroundings such as suspension media and the extracellular matrix (ECM) via two distinct but related mechanisms-water transport and cytoskeletal mechanics. The underlying rationale is that the cytoplasm of the cells has poroelastic nature, which can regulate both cellular water transport and cytoskeletal mechanics. A poroelasticity-based cell dehydration model is developed and confirmed to provide insight into the effects of the hydraulic conductivity and stiffness of the cytoplasm on the dehydration of cells in suspension during freezing. We further investigated the effect of the cytoskeletal structures on the cryoresponse of cells embedded in the ECM by measuring the spatio-temporal intracellular deformation with dermal equivalent as a model tissue. The freezing-induced change in cell, nucleus and cytoplasm volume was quantified, and the possible mechanism of the volumetric change was proposed. The results are discussed considering the hierarchical poroelasticity of biological tissues. PMID- 27707906 TI - Trade-off between disease resistance and crop yield: a landscape-scale mathematical modelling perspective. AB - The deployment of crop varieties that are partially resistant to plant pathogens is an important method of disease control. However, a trade-off may occur between the benefits of planting the resistant variety and a yield penalty, whereby the standard susceptible variety outyields the resistant one in the absence of disease. This presents a dilemma: deploying the resistant variety is advisable only if the disease occurs and is sufficient for the resistant variety to outyield the infected standard variety. Additionally, planting the resistant variety carries with it a further advantage in that the resistant variety reduces the probability of disease invading. Therefore, viewed from the perspective of a grower community, there is likely to be an optimal trade-off and thus an optimal cropping density for the resistant variety. We introduce a simple stochastic, epidemiological model to investigate the trade-off and the consequences for crop yield. Focusing on susceptible-infected-removed epidemic dynamics, we use the final size equation to calculate the surviving host population in order to analyse the yield, an approach suitable for rapid epidemics in agricultural crops. We identify a single compound parameter, which we call the efficacy of resistance and which incorporates the changes in susceptibility, infectivity and durability of the resistant variety. We use the compound parameter to inform policy plots that can be used to identify the optimal strategy for given parameter values when an outbreak is certain. When the outbreak is uncertain, we show that for some parameter values planting the resistant variety is optimal even when it would not be during the outbreak. This is because the resistant variety reduces the probability of an outbreak occurring. PMID- 27707907 TI - On the possibility of galactic cosmic ray-induced radiolysis-powered life in subsurface environments in the Universe. AB - Photosynthesis is a mechanism developed by terrestrial life to utilize the energy from photons of solar origin for biological use. Subsurface regions are isolated from the photosphere, and consequently are incapable of utilizing this energy. This opens up the opportunity for life to evolve alternative mechanisms for harvesting available energy. Bacterium Candidatus Desulforudis audaxviator, found 2.8 km deep in a South African mine, harvests energy from radiolysis, induced by particles emitted from radioactive U, Th and K present in surrounding rock. Another radiation source in the subsurface environments is secondary particles generated by galactic cosmic rays (GCRs). Using Monte Carlo simulations, it is shown that it is a steady source of energy comparable to that produced by radioactive substances, and the possibility of a slow metabolizing life flourishing on it cannot be ruled out. Two mechanisms are proposed through which GCR-induced secondary particles can be utilized for biological use in subsurface environments: (i) GCRs injecting energy in the environment through particle induced radiolysis and (ii) organic synthesis from GCR secondaries interacting with the medium. Laboratory experiments to test these hypotheses are also proposed. Implications of these mechanisms on finding life in the Solar System and elsewhere in the Universe are discussed. PMID- 27707908 TI - Arsenate reductase from Thermus thermophilus conjugated to polyethylene glycol stabilized gold nanospheres allow trace sensing and speciation of arsenic ions. AB - Water sources pollution by arsenic ions is a serious environmental problem all around the world. Arsenate reductase enzyme (TtArsC) from Thermus thermophilus extremophile bacterium, naturally binds arsenic ions, As(V) and As (III), in aqueous solutions. In this research, TtArsC enzyme adsorption onto hybrid polyethylene glycol-stabilized gold nanoparticles (AuNPs) was studied at different pH values as an innovative nanobiosystem for metal concentration monitoring. Characterizations were performed by UV/Vis and circular dichroism spectroscopies, TEM images and in terms of surface charge changes. The molecular interaction between arsenic ions and the TtArsC-AuNPs nanobiosystem was also monitored at all pH values considered by UV/Vis spectroscopy. Tests performed revealed high sensitivities and limits of detection equal to 10 +/- 3 M-12 and 7.7 +/- 0.3 M-12 for As(III) and As(V), respectively. PMID- 27707911 TI - Introductory paragraph. PMID- 27707909 TI - Characterizing the reproduction number of epidemics with early subexponential growth dynamics. AB - Early estimates of the transmission potential of emerging and re-emerging infections are increasingly used to inform public health authorities on the level of risk posed by outbreaks. Existing methods to estimate the reproduction number generally assume exponential growth in case incidence in the first few disease generations, before susceptible depletion sets in. In reality, outbreaks can display subexponential (i.e. polynomial) growth in the first few disease generations, owing to clustering in contact patterns, spatial effects, inhomogeneous mixing, reactive behaviour changes or other mechanisms. Here, we introduce the generalized growth model to characterize the early growth profile of outbreaks and estimate the effective reproduction number, with no need for explicit assumptions about the shape of epidemic growth. We demonstrate this phenomenological approach using analytical results and simulations from mechanistic models, and provide validation against a range of empirical disease datasets. Our results suggest that subexponential growth in the early phase of an epidemic is the rule rather the exception. Mechanistic simulations show that slight modifications to the classical susceptible-infectious-removed model result in subexponential growth, and in turn a rapid decline in the reproduction number within three to five disease generations. For empirical outbreaks, the generalized-growth model consistently outperforms the exponential model for a variety of directly and indirectly transmitted diseases datasets (pandemic influenza, measles, smallpox, bubonic plague, cholera, foot-and-mouth disease, HIV/AIDS and Ebola) with model estimates supporting subexponential growth dynamics. The rapid decline in effective reproduction number predicted by analytical results and observed in real and synthetic datasets within three to five disease generations contrasts with the expectation of invariant reproduction number in epidemics obeying exponential growth. The generalized-growth concept also provides us a compelling argument for the unexpected extinction of certain emerging disease outbreaks during the early ascending phase. Overall, our approach promotes a more reliable and data-driven characterization of the early epidemic phase, which is important for accurate estimation of the reproduction number and prediction of disease impact. PMID- 27707912 TI - Novel role of Vav1-Rac1 pathway in actin cytoskeleton regulation in Interleukin 13-induced minimal change-like nephropathy. AB - Our established interleukin-13 ( IL-13 ) overexpression rat model of minimal change-like nephropathy provided a platform to study the molecular signalling pathways in T-helper 2 (Th2) cytokine associated minimal change nephrotic syndrome. We hypothesized that IL-13 may act directly on podocytes, causing podocyte foot process effacement and hence proteinuria in our rat model of minimal change-like nephropathy. This study aimed firstly to delineate the glomerular "gene signature" associated with IL-13-mediated dysregulation of podocyte related proteins, and subsequently to investigate the role of the differentially regulated genes in IL-13-mediated podocyte injury. Glomerular transcriptional profile of IL-13 -overexpressed rats showed characteristic features of podocyte injury with 87% of podocyte related genes being significantly down-regulated. Gene expression of Vav1 was shown to be highly up regulated in the glomeruli of IL-13 -overexpressed rats and pathway analysis of the differentially expressed genes suggested a possible novel role of Vav1 in podocyte cytoskeleton remodelling. Immunofluorescence examination demonstrated glomerular expression of Vav1 in rats which co-localized with synaptopodin, confirming podocyte expression. However, positive staining for the phosphorylated form of Vav1 (p-Vav1) was only seen in IL-13 -overexpressed rats. Moreover, in vitro IL-13 stimulation of human podocytes resulted in phosphorylation of Vav1. This was associated with Rac1 activation and actin cytoskeleton rearrangement, which was abrogated in Vav1 knock-down podocytes. In conclusion, we have demonstrated the role of Vav1-Rac1 pathway characterised by phosphorylation of Vav1, activation of Rac1 and the subsequent actin cytoskeleton rearrangement in IL-13 induced podocyte injury, possibly explaining the podocyte foot process effacement seen in our IL-13 overexpression rat model. PMID- 27707910 TI - Musculoskeletal modelling under an evolutionary perspective: deciphering the role of single muscle regions in closely related insects. AB - Insects show a remarkable diversity of muscle configurations, yet the factors leading to this functional diversity are poorly understood. Here, we use musculoskeletal modelling to understand the spatio-temporal activity of an insect muscle in several dragonfly species and to reveal potential mechanical factors leading to a particular muscle configuration. Bite characteristics potentially show systematic signal, but absolute bite force is not correlated with size. Muscle configuration and inverse dynamics show that the wider relative area of muscle attachment and the higher activity of subapical muscle groups are responsible for this high bite force. This wider attachment area is, however, not an evolutionary trend within dragonflies. Our inverse dynamic data, furthermore, show that maximum bite forces most probably do not reflect maximal muscle force production capability in all studied species. The thin head capsule and the attachment areas of muscles most probably limit the maximum force output of the mandibular muscles. PMID- 27707913 TI - Need for Outcome Scenario Analysis of Clinical Trials in Diabetes. AB - Since the FDA requirement for cardiovascular safety of all new antihyperglycemic drugs to enter the market, the number and extent of phase 3 clinical trials has markedly increased. Unexpected trial results imply an enormous economic, personal and time cost and has deleterious effects over R&D. To prevent unforeseen developments in clinical trials, we recommend performing a comprehensive prospective outcome scenario analysis before launching the trial. In this commentary, we discuss the most important factors to take in consideration for prediction of clinical trial outcome scenarios and propose a theoretical model for decision making.

AB - Continuous standardized verification of the accuracy of blood glucose meter systems for self-monitoring after their introduction into the market is an important clinically tool to assure reliable performance of subsequently released lots of strips.

PMID- 27707916 TI - Antibiotic Prescribing by Physicians Versus Nurse Practitioners for Pediatric Upper Respiratory Infections. AB - BACKGROUND: This study investigates differences in antibiotic prescribing rates for pediatric upper respiratory infections (URIs) between physicians and nurse practitioners (NPs). METHODS: Visits by children <18 years old diagnosed with URI to physicians or NPs between 2001 and 2010 were abstracted from the National Ambulatory Medical Care Survey and National Hospital Ambulatory Care Survey. Logistic regression analyses examined variations in antibiotic prescribing rates. RESULTS: Upper respiratory infections accounted for approximately 439 +/- 21.5 million visits. Patients seen by NPs were more likely to have Medicaid, live in the lowest median household income quartile zip codes and micropolitan locations, and live in the South compared to patients seen by physicians. Nurse practitioners prescribed antibiotics 66.7% +/- 4.2% of the time versus physicians at 52.8% +/- 0.8% for URI visits (unadjusted P-value = .002). Adjusted by specialty, URI type, and chronic diseases, NPs had marginally significantly different odds of prescribing antibiotics (OR = 1.6, 95% CI, 1.0-2.6, P-value = .048), but the association with prescribing broad-spectrum antibiotics is not as strong (adjusted P-value = .063). Patient visits to a pediatric (OR = 0.54, 95% CI, 0.43-0.67) or ENT/surgery practice (OR = 0.11, 95% CI, 0.06-0.18) had lower odds of antibiotic prescribing compared to general/family medicine practices. Year (2001-2010) was not significantly associated with antibiotic or broad spectrum antibiotic prescribing rates for physicians, but rates for NPs fell for otitis media (P-value = .007) from 90.2% +/- 8.2% (2001-2002) to 74.8% +/- 6.8% (2009-2010) of visits. CONCLUSIONS: Nurse practitioners have higher rates of antibiotic prescribing compared to physicians for pediatric patients with URIs; however, this difference is less after adjusting for specialty. Examining comparative antibiotic prescribing is important to promote evidence-based practice and adoption of clinical guidelines. PMID- 27707917 TI - Identification of Interferon-Stimulated Gene Proteins That Inhibit Human Parainfluenza Virus Type 3. AB - : A major arm of cellular innate immunity is type I interferon (IFN), represented by IFN-alpha and IFN-beta. Type I IFN transcriptionally induces a large number of cellular genes, collectively known as IFN-stimulated gene (ISG) proteins, which act as antivirals. The IFIT (interferon-induced proteins with tetratricopeptide repeats) family proteins constitute a major subclass of ISG proteins and are characterized by multiple tetratricopeptide repeats (TPRs). In this study, we have interrogated IFIT proteins for the ability to inhibit the growth of human parainfluenza virus type 3 (PIV3), a nonsegmented negative-strand RNA virus of the Paramyxoviridae family and a major cause of respiratory disease in children. We found that IFIT1 significantly inhibited PIV3, whereas IFIT2, IFIT3, and IFIT5 were less effective or not at all. In further screening a set of ISG proteins we discovered that several other such proteins also inhibited PIV3, including IFITM1, IDO (indoleamine 2,3-dioxygenase), PKR (protein kinase, RNA activated), and viperin (virus inhibitory protein, endoplasmic reticulum associated, interferon inducible)/Cig5. The antiviral effect of IDO, the enzyme that catalyzes the first step of tryptophan degradation, could be counteracted by tryptophan. These results advance our knowledge of diverse ISG proteins functioning as antivirals and may provide novel approaches against PIV3. IMPORTANCE: The innate immunity of the host, typified by interferon (IFN), is a major antiviral defense. IFN inhibits virus growth by inducing a large number of IFN-stimulated gene (ISG) proteins, several of which have been shown to have specific antiviral functions. Parainfluenza virus type 3 (PIV3) is major pathogen of children, and no reliable vaccine or specific antiviral against it currently exists. In this article, we report several ISG proteins that strongly inhibit PIV3 growth, the use of which may allow a better antiviral regimen targeting PIV3. PMID- 27707918 TI - Foot-and-Mouth Disease Virus Viroporin 2B Antagonizes RIG-I-Mediated Antiviral Effects by Inhibition of Its Protein Expression. AB - : The role of retinoic acid-inducible gene I (RIG-I) in foot-and-mouth disease virus (FMDV)-infected cells remains unknown. Here, we showed that RIG-I inhibits FMDV replication in host cells. FMDV infection increased the transcription of RIG I, while it decreased RIG-I protein expression. A detailed analysis revealed that FMDV leader proteinase (Lpro), as well as 3C proteinase (3Cpro) and 2B protein, decreased RIG-I protein expression. Lpro and 3Cpro are viral proteinases that can cleave various host proteins and are responsible for several of the viral polyprotein cleavages. However, for the first time, we observed 2B-induced reduction of host protein. Further studies showed that 2B-mediated reduction of RIG-I is specific to FMDV, but not other picornaviruses, including encephalomyocarditis virus, enterovirus 71, and coxsackievirus A16. Moreover, we found the decreased protein level of RIG-I is independent of the cleavage of eukaryotic translation initiation factor 4 gamma, the induction of cellular apoptosis, or the association of proteasome, lysosome, and caspase pathways. A direct interaction was observed between RIG-I and 2B. The carboxyl-terminal amino acids 105 to 114 and amino acids 135 to 144 of 2B were essential for the reduction of RIG-I, while residues 105 to 114 were required for the interaction. These data suggest the antiviral role of RIG-I against FMDV and a novel antagonistic mechanism of FMDV that is mediated by 2B protein. IMPORTANCE: This study demonstrated that RIG-I could suppress FMDV replication during virus infection. FMDV infection increased the transcriptional expression of RIG-I, while it decreased RIG-I protein expression. FMDV 2B protein interacted with RIG I and induced reduction of RIG-I. 2B-induced reduction of RIG-I was independent of the induction of the cleavage of eukaryotic translation initiation factor 4 gamma or cellular apoptosis. In addition, proteasome, lysosome, and caspase pathways were not involved in this process. This study provides new insight into the immune evasion mediated by FMDV and identifies 2B as an antagonistic factor for FMDV to evade the antiviral response. PMID- 27707919 TI - Simian Immunodeficiency Virus-Producing Cells in Follicles Are Partially Suppressed by CD8+ Cells In Vivo. AB - : Human immunodeficiency virus (HIV)- and simian immunodeficiency virus (SIV) specific CD8+ T cells are typically largely excluded from lymphoid B cell follicles, where HIV- and SIV-producing cells are most highly concentrated, indicating that B cell follicles are somewhat of an immunoprivileged site. To gain insights into virus-specific follicular CD8+ T cells, we determined the location and phenotype of follicular SIV-specific CD8+ T cells in situ, the local relationship of these cells to Foxp3+ cells, and the effects of CD8 depletion on levels of follicular SIV-producing cells in chronically SIV-infected rhesus macaques. We found that follicular SIV-specific CD8+ T cells were able to migrate throughout follicular areas, including germinal centers. Many expressed PD-1, indicating that they may have been exhausted. A small subset was in direct contact with and likely inhibited by Foxp3+ cells, and a few were themselves Foxp3+ In addition, subsets of follicular SIV-specific CD8+ T cells expressed low to medium levels of perforin, and subsets were activated and proliferating. Importantly, after CD8 depletion, the number of SIV-producing cells increased in B cell follicles and extrafollicular areas, suggesting that follicular and extrafollicular CD8+ T cells have a suppressive effect on SIV replication. Taken together, these results suggest that during chronic SIV infection, despite high levels of exhaustion and likely inhibition by Foxp3+ cells, a subset of follicular SIV-specific CD8+ T cells are functional and suppress viral replication in vivo These findings support HIV cure strategies that augment functional follicular virus-specific CD8+ T cells to enhance viral control. IMPORTANCE: HIV- and SIV-specific CD8+ T cells are typically largely excluded from lymphoid B cell follicles, where virus-producing cells are most highly concentrated, suggesting that B cell follicles are somewhat of an immunoprivileged site where virus-specific CD8+ T cells are not able to clear all follicular HIV- and SIV-producing cells. To gain insights into follicular CD8+ T cell function, we characterized follicular virus-specific CD8+ T cells in situ by using an SIV-infected rhesus macaque model of HIV. We found that subsets of follicular SIV-specific CD8+ T cells are able to migrate throughout the follicle, are likely inhibited by Foxp3+ cells, and are likely exhausted but that, nonetheless, subsets are likely functional, as they express markers consistent with effector function and show signs of suppressing viral replication in vivo These findings support HIV cure strategies that increase the frequency of functional follicular virus-specific CD8+ T cells. PMID- 27707920 TI - Rationally Designed Immunogens Targeting HIV-1 gp120 V1V2 Induce Distinct Conformation-Specific Antibody Responses in Rabbits. AB - : The V1V2 region of HIV-1 gp120 harbors a major vulnerable site targeted by a group of broadly neutralizing monoclonal antibodies (MAbs) such as PG9 through strand-strand recognition. However, this epitope region is structurally polymorphic as it can also form a helical conformation recognized by RV144 vaccine-induced MAb CH58. This structural polymorphism is a potential mechanism for masking the V1V2 vulnerable site. Designing immunogens that can induce conformation-specific antibody (Ab) responses may lead to vaccines targeting this vulnerable site. We designed a panel of immunogens engrafting the V1V2 domain into trimeric and pentameric scaffolds in structurally constrained conformations. We also fused V1V2 to an Fc fragment to mimic the unconstrained V1V2 conformation. We tested these V1V2-scaffold proteins for immunogenicity in rabbits and assessed the responses by enzyme-linked immunosorbent assay (ELISA) and competition assays. Our V1V2 immunogens induced distinct conformation specific Ab responses. Abs induced by structurally unconstrained immunogens reacted preferentially with unconstrained V1V2 antigens, suggesting recognition of the helical configuration, while Abs induced by the structurally constrained immunogens reacted preferentially with constrained V1V2 antigens, suggesting recognition of the beta-strand conformation. The Ab responses induced by the structurally constrained immunogens were more broadly reactive and had higher titers than those induced by the structurally unconstrained immunogens. Our results demonstrate that immunogens presenting the different structural conformations of the gp120 V1V2 vulnerable site can be designed and that these immunogens induce distinct Ab responses with epitope conformation specificity. Therefore, these structurally constrained V1V2 immunogens are vaccine prototypes targeting the V1V2 domain of the HIV-1 envelope. IMPORTANCE: The correlates analysis of the RV144 HIV-1 vaccine trial suggested that the presence of antibodies to the V1V2 region of HIV-1 gp120 was responsible for the modest protection observed in the trial. In addition, V1V2 harbors one of the key vulnerable sites of HIV-1 Env recognized by a family of broadly neutralizing MAbs such as PG9. Thus, V1V2 is a key target for vaccine development. However, this vulnerable site is structurally polymorphic, and designing immunogens that present different conformations is crucial for targeting this site. We show here that such immunogens can be designed and that they induced conformation-specific antibody responses in rabbits. Our immunogens are therefore prototypes of vaccine candidates targeting the V1V2 region of HIV-1 Env. PMID- 27707921 TI - The Intracellular Cholesterol Transport Inhibitor U18666A Inhibits the Exosome Dependent Release of Mature Hepatitis C Virus. AB - : Hepatitis C virus (HCV) particles are described as lipoviroparticles which are released similarly to very-low-density lipoproteins (VLDLs). However, the release mechanism is still poorly understood; the canonical endoplasmic reticulum-Golgi intermediate compartment (ERGIC) pathway as well as endosome-dependent release has been proposed. Recently, the role of exosomes in the transmission of HCV has been reported. Only a minor fraction of the de novo-synthesized lipoviroparticles is released by the infected cell. To investigate the relevance of multivesicular bodies (MVBs) for viral morphogenesis and release, the MVB inhibitor U18666A was used. Intracellular trafficking was analyzed by confocal microscopy and electron microscopy. Moreover, an mCherry-tagged HCV variant was used. Conditions were established that enable U18666A-dependent inhibition of MVBs without affecting viral replication. Under these conditions, significant inhibition of the HCV release was observed. The assembly of viral particles is not affected. In U18666A treated cells, intact infectious viral particles accumulate in CD63-positive exosomal structures and large dysfunctional lysosomal structures (multilamellar bodies). These retained particles possess a lower density, reflecting a misloading with lipids. Our data indicate that at least a fraction of HCV particles leaves the cell via the endosomal pathway. Endosomes facilitate the sorting of HCV particles for release or degradation. IMPORTANCE: There are still a variety of open questions regarding morphogenesis and release of hepatitis C virus. The HCV-infected cell produces significant more viral particles that are released, raising the question about the fate of the nonreleased particles. Moreover, the relevance of the endosomal pathway for the release of HCV is under debate. Use of the MVB (multivesicular body) inhibitor U18666A enabled a detailed analysis of the impact of MVBs for viral morphogenesis and release. It was revealed that infectious, fully assembled HCV particles are either MVB dependently released or intracellularly degraded by the lysosome. Our data indicate that at least a fraction of HCV particles leaves the cell via the endosomal pathway independent from the constitutive secretory pathway. Our study describes a so-far-unprecedented cross talk between two pathways regulating on the one hand the release of infectious viral particles and on the other hand the intracellular degradation of nonreleased particles. PMID- 27707922 TI - Syncytial Mutations Do Not Impair the Specificity of Entry and Spread of a Glycoprotein D Receptor-Retargeted Herpes Simplex Virus. AB - : Membrane fusion, which is the key process for both initial cell entry and subsequent lateral spread of herpes simplex virus (HSV), requires the four envelope glycoproteins gB, gD, gH, and gL. Syncytial mutations, predominantly mapped to the gB and gK genes, confer hyperfusogenicity on HSV and cause multinucleated giant cells, termed syncytia. Here we asked whether interaction of gD with a cognate entry receptor remains indispensable for initiating membrane fusion of syncytial strains. To address this question, we took advantage of mutant viruses whose viral entry into cells relies on the uniquely specific interaction of an engineered gD with epidermal growth factor receptor (EGFR). We introduced selected syncytial mutations into gB and/or gK of the EGFR-retargeted HSV and found that these mutations, especially when combined, enabled formation of extensive syncytia by human cancer cell lines that express the target receptor; these syncytia were substantially larger than the plaques formed by the parental retargeted HSV strain. We assessed the EGFR dependence of entry and spread separately by using direct entry and infectious center assays, respectively, and we found that the syncytial mutations did not override the receptor specificity of the retargeted viruses at either stage. We discuss the implications of these results for the development of more effective targeted oncolytic HSV vectors. IMPORTANCE: Herpes simplex virus (HSV) is investigated not only as a human pathogen but also as a promising agent for oncolytic virotherapy. We previously showed that both the initial entry and subsequent lateral spread of HSV can be retargeted to cells expressing tumor-associated antigens by single chain antibodies fused to a receptor-binding-deficient envelope glycoprotein D (gD). Here we introduced syncytial mutations into the gB and/or gK gene of gD retargeted HSVs to determine whether viral tropism remained dependent on the interaction of gD with the target receptor. Entry and spread profiles of the recombinant viruses indicated that gD retargeting does not abolish the hyperfusogenic activity of syncytial mutations and that these mutations do not eliminate the dependence of HSV entry and spread on a specific gD-receptor interaction. These observations suggest that syncytial mutations may be valuable for increasing the tumor-specific spreading of retargeted oncolytic HSV vectors. PMID- 27707923 TI - Heterodimers as the Structural Unit of the T=1 Capsid of the Fungal Double Stranded RNA Rosellinia necatrix Quadrivirus 1. AB - : Most double-stranded RNA (dsRNA) viruses are transcribed and replicated in a specialized icosahedral capsid with a T=1 lattice consisting of 60 asymmetric capsid protein (CP) dimers. These capsids help to organize the viral genome and replicative complex(es). They also act as molecular sieves that isolate the virus genome from host defense mechanisms and allow the passage of nucleotides and viral transcripts. Rosellinia necatrix quadrivirus 1 (RnQV1), the type species of the family Quadriviridae, is a dsRNA fungal virus with a multipartite genome consisting of four monocistronic segments (segments 1 to 4). dsRNA-2 and dsRNA-4 encode two CPs (P2 and P4, respectively), which coassemble into ~450-A-diameter capsids. We used three-dimensional cryo-electron microscopy combined with complementary biophysical techniques to determine the structures of RnQV1 virion strains W1075 and W1118. RnQV1 has a quadripartite genome, and the capsid is based on a single-shelled T=1 lattice built of P2-P4 dimers. Whereas the RnQV1 W1118 capsid is built of full-length CP, P2 and P4 of RnQV1-W1075 are cleaved into several polypeptides, maintaining the capsid structural organization. RnQV1 heterodimers have a quaternary organization similar to that of homodimers of reoviruses and other dsRNA mycoviruses. The RnQV1 capsid is the first T=1 capsid with a heterodimer as an asymmetric unit reported to date and follows the architectural principle for dsRNA viruses that a 120-subunit capsid is a conserved assembly that supports dsRNA replication and organization. IMPORTANCE: Given their importance to health, members of the family Reoviridae are the basis of most structural and functional studies and provide much of our knowledge of dsRNA viruses. Analysis of bacterial, protozoal, and fungal dsRNA viruses has improved our understanding of their structure, function, and evolution, as well. Here, we studied a dsRNA virus that infects the fungus Rosellinia necatrix, an ascomycete that is pathogenic to a wide range of plants. Using three-dimensional cryo-electron microscopy and analytical ultracentrifugation analysis, we determined the structure and stoichiometry of Rosellinia necatrix quadrivirus 1 (RnQV1). The RnQV1 capsid is a T=1 capsid with 60 heterodimers as the asymmetric units. The large amount of genetic information used by RnQV1 to construct a simple T=1 capsid is probably related to the numerous virus-host and virus-virus interactions that it must face in its life cycle, which lacks an extracellular phase. PMID- 27707924 TI - The Tetherin Antagonism of the Ebola Virus Glycoprotein Requires an Intact Receptor-Binding Domain and Can Be Blocked by GP1-Specific Antibodies. AB - : The glycoprotein of Ebola virus (EBOV GP), a member of the family Filoviridae, facilitates viral entry into target cells. In addition, EBOV GP antagonizes the antiviral activity of the host cell protein tetherin, which may otherwise restrict EBOV release from infected cells. However, it is unclear how EBOV GP antagonizes tetherin, and it is unknown whether the GP of Lloviu virus (LLOV), a filovirus found in dead bats in Northern Spain, also counteracts tetherin. Here, we show that LLOV GP antagonizes tetherin, indicating that tetherin may not impede LLOV spread in human cells. Moreover, we demonstrate that appropriate processing of N-glycans in tetherin/GP-coexpressing cells is required for tetherin counteraction by EBOV GP. Furthermore, we show that an intact receptor binding domain (RBD) in the GP1 subunit of EBOV GP is a prerequisite for tetherin counteraction. In contrast, blockade of Niemann-Pick disease type C1 (NPC1), a cellular binding partner of the RBD, did not interfere with tetherin antagonism. Finally, we provide evidence that an antibody directed against GP1, which protects mice from a lethal EBOV challenge, may block GP-dependent tetherin antagonism. Our data, in conjunction with previous reports, indicate that tetherin antagonism is conserved among the GPs of all known filoviruses and demonstrate that the GP1 subunit of EBOV GP plays a central role in tetherin antagonism. IMPORTANCE: Filoviruses are reemerging pathogens that constitute a public health threat. Understanding how Ebola virus (EBOV), a highly pathogenic filovirus responsible for the 2013-2016 Ebola virus disease epidemic in western Africa, counteracts antiviral effectors of the innate immune system might help to define novel targets for antiviral intervention. Similarly, determining whether Lloviu virus (LLOV), a filovirus detected in bats in northern Spain, is inhibited by innate antiviral effectors in human cells might help to determine whether the virus constitutes a threat to humans. The present study shows that LLOV, like EBOV, counteracts the antiviral effector protein tetherin via its glycoprotein (GP), suggesting that tetherin does not pose a defense against LLOV spread in humans. Moreover, our work identifies the GP1 subunit of EBOV GP, in particular an intact receptor-binding domain, as critical for tetherin counteraction and provides evidence that antibodies directed against GP1 can interfere with tetherin counteraction. PMID- 27707926 TI - Repression of the Chromatin-Tethering Domain of Murine Leukemia Virus p12. AB - : Murine leukemia virus (MLV) p12, encoded within Gag, binds the viral preintegration complex (PIC) to the mitotic chromatin. This acts to anchor the viral PIC in the nucleus as the nuclear envelope re-forms postmitosis. Mutations within the p12 C terminus (p12 PM13 to PM15) block early stages in viral replication. Within the p12 PM13 region (p12 60PSPMA65), our studies indicated that chromatin tethering was not detected when the wild-type (WT) p12 protein (M63) was expressed as a green fluorescent protein (GFP) fusion; however, constructs bearing p12-I63 were tethered. N-terminal truncations of the activated p12-I63-GFP indicated that tethering increased further upon deletion of p12 25DLLTEDPPPY34, which includes the late domain required for viral assembly. The p12 PM15 sequence (p12 70RREPP74) is critical for wild-type viral viability; however, virions bearing the PM15 mutation (p12 70AAAAA74) with a second M63I mutant were viable, with a titer 18-fold lower than that of the WT. The p12 M63I mutation amplified chromatin tethering and compensated for the loss of chromatin binding of p12 PM15. Rescue of the p12-M63-PM15 nonviable mutant with prototype foamy virus (PFV) and Kaposi's sarcoma herpesvirus (KSHV) tethering sequences confirmed the function of p1270-74 in chromatin binding. Minimally, full-strength tethering was seen with only p12 61SPIASRLRGRR71 fused to GFP. These results indicate that the p12 C terminus alone is sufficient for chromatin binding and that the presence of the p12 25DLLTEDPPPY34 motif in the N terminus suppresses the ability to tether. IMPORTANCE: This study defines a regulatory mechanism controlling the differential roles of the MLV p12 protein in early and late replication. During viral assembly and egress, the late domain within the p12 N terminus functions to bind host vesicle release factors. During viral entry, the C terminus of p12 is required for tethering to host mitotic chromosomes. Our studies indicate that the p12 domain including the PPPY late sequence temporally represses the p12 chromatin tethering motif. Maximal p12 tethering was identified with only an 11-amino-acid minimal chromatin tethering motif encoded at p1261-71 Within this region, the p12-M63I substitution switches p12 into a tethering competent state, partially rescuing the p12-PM15 tethering mutant. A model for how this conformational change regulates early versus late functions is presented. PMID- 27707925 TI - HIV-1 Glycan Density Drives the Persistence of the Mannose Patch within an Infected Individual. AB - : The HIV envelope glycoprotein (Env) is extensively modified with host-derived N linked glycans. The high density of glycosylation on the viral spike limits enzymatic processing, resulting in numerous underprocessed oligomannose-type glycans. This extensive glycosylation not only shields conserved regions of the protein from the immune system but also acts as a target for anti-HIV broadly neutralizing antibodies (bnAbs). In response to the host immune system, the HIV glycan shield is constantly evolving through mutations affecting both the positions and numbers of potential N-linked glycosylation sites (PNGSs). Here, using longitudinal Env sequences from a clade C-infected individual (CAP256), we measured the impact of the shifting glycan shield during HIV infection on the abundance of oligomannose-type glycans. By analyzing the intrinsic mannose patch from a panel of recombinant CAP256 gp120s displaying high protein sequence variability and changes in PNGS number and positioning, we show that the intrinsic mannose patch persists throughout the course of HIV infection and correlates with the number of PNGSs. This effect of the glycan density on the processing state was also supported by the analysis of a cross-clade panel of recombinant gp120 glycoproteins. Together, these observations underscore the importance of glycan clustering for the generation of carbohydrate epitopes for anti-HIV bnAbs. The persistence of the intrinsic mannose patch over the course of HIV infection further highlights this epitope as an important target for HIV vaccine strategies. IMPORTANCE: Development of an HIV vaccine is critical for control of the HIV pandemic, and elicitation of broadly neutralizing antibodies (bnAbs) is likely to be a key component of a successful vaccine response. The HIV envelope glycoprotein (Env) is covered in an array of host-derived N-linked glycans often referred to as the glycan shield. This glycan shield is a target for many of the recently isolated anti-HIV bnAbs and is therefore under constant pressure from the host immune system, leading to changes in both glycan site frequency and location. This study aimed to determine whether these genetic changes impacted the eventual processing of glycans on the HIV Env and the susceptibility of the virus to neutralization. We show that despite this variation in glycan site positioning and frequency over the course of HIV infection, the mannose patch is a conserved feature throughout, making it a stable target for HIV vaccine design. PMID- 27707927 TI - TMPRSS12 Is an Activating Protease for Subtype B Avian Metapneumovirus. AB - : The entry of avian metapneumovirus (aMPV) into host cells initially requires the fusion of viral and cell membranes, which is exclusively mediated by fusion (F) protein. Proteolysis of aMPV F protein by endogenous proteases of host cells allows F protein to induce membrane fusion; however, these proteases have not been identified. Here, we provide the first evidence that the transmembrane serine protease TMPRSS12 facilitates the cleavage of subtype B aMPV (aMPV/B) F protein. We found that overexpression of TMPRSS12 enhanced aMPV/B F protein cleavage, F protein fusogenicity, and viral replication. Subsequently, knockdown of TMPRSS12 with specific small interfering RNAs (siRNAs) reduced aMPV/B F protein cleavage, F protein fusogenicity, and viral replication. We also found a cleavage motif in the aMPV/B F protein (amino acids 100 and 101) that was recognized by TMPRSS12. The histidine, aspartic acid, and serine residue (HDS) triad of TMPRSS12 was shown to be essential for the proteolysis of aMPV/B F protein via mutation analysis. Notably, we observed TMPRSS12 mRNA expression in target organs of aMPV/B in chickens. Overall, our results indicate that TMPRSS12 is crucial for aMPV/B F protein proteolysis and aMPV/B infectivity and that TMPRSS12 may serve as a target for novel therapeutics and prophylactics for aMPV. IMPORTANCE: Proteolysis of the aMPV F protein is a prerequisite for F protein mediated membrane fusion of virus and cell and for aMPV infection; however, the proteases used in vitro and vivo are not clear. A combination of analyses, including overexpression, knockdown, and mutation methods, demonstrated that the transmembrane serine protease TMPRSS12 facilitated cleavage of subtype B aMPV (aMPV/B) F protein. Importantly, we located the motif in the aMPV/B F protein recognized by TMPRSS12 and the catalytic triad in TMPRSS12 that facilitated proteolysis of the aMPV/B F protein. This is the first report on TMPRSS12 as a protease for proteolysis of viral envelope glycoproteins. Our study will shed light on the mechanism of proteolysis of aMPV F protein and pathogenesis of aMPV. PMID- 27707929 TI - Constitutively Expressed IFITM3 Protein in Human Endothelial Cells Poses an Early Infection Block to Human Influenza Viruses. AB - : A role for pulmonary endothelial cells in the orchestration of cytokine production and leukocyte recruitment during influenza virus infection, leading to severe lung damage, has been recently identified. As the mechanistic pathway for this ability is not fully known, we extended previous studies on influenza virus tropism in cultured human pulmonary endothelial cells. We found that a subset of avian influenza viruses, including potentially pandemic H5N1, H7N9, and H9N2 viruses, could infect human pulmonary endothelial cells (HULEC) with high efficiency compared to human H1N1 or H3N2 viruses. In HULEC, human influenza viruses were capable of binding to host cellular receptors, becoming internalized and initiating hemifusion but failing to uncoat the viral nucleocapsid and to replicate in host nuclei. Unlike numerous cell types, including epithelial cells, we found that pulmonary endothelial cells constitutively express a high level of the restriction protein IFITM3 in endosomal compartments. IFITM3 knockdown by small interfering RNA (siRNA) could partially rescue H1N1 virus infection in HULEC, suggesting IFITM3 proteins were involved in blocking human influenza virus infection in endothelial cells. In contrast, selected avian influenza viruses were able to escape IFITM3 restriction in endothelial cells, possibly by fusing in early endosomes at higher pH or by other, unknown mechanisms. Collectively, our study demonstrates that the human pulmonary endothelium possesses intrinsic immunity to human influenza viruses, in part due to the constitutive expression of IFITM3 proteins. Notably, certain avian influenza viruses have evolved to escape this restriction, possibly contributing to virus-induced pneumonia and severe lung disease in humans. IMPORTANCE: Avian influenza viruses, including H5N1 and H7N9, have been associated with severe respiratory disease and fatal outcomes in humans. Although acute respiratory distress syndrome (ARDS) and progressive pulmonary endothelial damage are known to be present during severe human infections, the role of pulmonary endothelial cells in the pathogenesis of avian influenza virus infections is largely unknown. By comparing human seasonal influenza strains to avian influenza viruses, we provide greater insight into the interaction of influenza virus with human pulmonary endothelial cells. We show that human influenza virus infection is blocked during the early stages of virus entry, which is likely due to the relatively high expression of the host antiviral factors IFITMs (interferon-induced transmembrane proteins) located in membrane-bound compartments inside cells. Overall, this study provides a mechanism by which human endothelial cells limit replication of human influenza virus strains, whereas avian influenza viruses overcome these restriction factors in this cell type. PMID- 27707928 TI - Characterization of Human CD8 T Cell Responses in Dengue Virus-Infected Patients from India. AB - : Epidemiological studies suggest that India has the largest number of dengue virus infection cases worldwide. However, there is minimal information about the immunological responses in these patients. CD8 T cells are important in dengue, because they have been implicated in both protection and immunopathology. Here, we provide a detailed analysis of HLA-DR+ CD38+ and HLA-DR- CD38+ effector CD8 T cell subsets in dengue patients from India and Thailand. Both CD8 T cell subsets expanded and expressed markers indicative of antigen-driven proliferation, tissue homing, and cytotoxic effector functions, with the HLA-DR+ CD38+ subset being the most striking in these effector qualities. The breadth of the dengue-specific CD8 T cell response was diverse, with NS3-specific cells being the most dominant. Interestingly, only a small fraction of these activated effector CD8 T cells produced gamma interferon (IFN-gamma) when stimulated with dengue virus peptide pools. Transcriptomics revealed downregulation of key molecules involved in T cell receptor (TCR) signaling. Consistent with this, the majority of these CD8 T cells remained IFN-gamma unresponsive even after TCR-dependent polyclonal stimulation (anti-CD3 plus anti-CD28) but produced IFN-gamma by TCR-independent polyclonal stimulation (phorbol 12-myristate 13-acetate [PMA] plus ionomycin). Thus, the vast majority of these proliferating, highly differentiated effector CD8 T cells probably acquire TCR refractoriness at the time the patient is experiencing febrile illness that leads to IFN-gamma unresponsiveness. Our studies open novel avenues for understanding the mechanisms that fine-tune the balance between CD8 T cell-mediated protective versus pathological effects in dengue. IMPORTANCE: Dengue is becoming a global public health concern. Although CD8 T cells have been implicated both in protection and in the cytokine-mediated immunopathology of dengue, how the balance is maintained between these opposing functions remains unknown. We comprehensively characterized CD8 T cell subsets in dengue patients from India and Thailand and show that these cells expand massively and express phenotypes indicative of overwhelming antigenic stimulus and tissue homing/cytotoxic-effector functions but that a vast majority of them fail to produce IFN-gamma in vitro Interestingly, the cells were fully capable of producing the cytokine when stimulated in a T cell receptor (TCR)-independent manner but failed to do so in TCR-dependent stimulation. These results, together with transcriptomics, revealed that the vast majority of these CD8 T cells from dengue patients become cytokine unresponsive due to TCR signaling insufficiencies. These observations open novel avenues for understanding the mechanisms that fine-tune the balance between CD8-mediated protective versus pathological effects. PMID- 27707930 TI - Protective Capacity of the Human Anamnestic Antibody Response during Acute Dengue Virus Infection. AB - Half of the world's population is exposed to the risk of dengue virus infection. Although a vaccine for dengue virus is now available in a few countries, its reported overall efficacy of about 60% is not ideal. Protective immune correlates following natural dengue virus infection remain undefined, which makes it difficult to predict the efficacy of new vaccines. In this study, we address the protective capacity of dengue virus-specific antibodies that are produced by plasmablasts a few days after natural secondary infection. Among a panel of 18 dengue virus-reactive human monoclonal antibodies, four groups of antibodies were identified based on their binding properties. While antibodies targeting the fusion loop of the glycoprotein of dengue virus dominated the antibody response, two smaller groups of antibodies bound to previously undescribed epitopes in domain II of the E protein. The latter, largely serotype-cross-reactive antibodies, demonstrated increased stability of binding at pH 5. These antibodies possessed weak to moderate neutralization capacity in vitro but were the most efficacious in promoting the survival of infected mice. Our data suggest that the cross-reactive anamnestic antibody response has a protective capacity despite moderate neutralization in vitro and a moderate decrease of viremia in vivo IMPORTANCE: Antibodies can protect from symptomatic dengue virus infection. However, it is not easy to assess which classes of antibodies provide protection because in vitro assays are not always predictive of in vivo protection. During a repeat infection, dengue virus-specific immune memory cells are reactivated and large amounts of antibodies are produced. By studying antibodies cloned from patients with heterologous secondary infection, we tested the protective value of the serotype-cross-reactive "recall" or "anamnestic" response. We found that results from in vitro neutralization assays did not always correlate with the ability of the antibodies to reduce viremia in a mouse model. In addition, a decrease of viremia in mice did not necessarily improve survival. The most protective antibodies were stable at pH 5, suggesting that antibody binding in the endosomes, after the antibody-virus complex is internalized, might be important to block virus spread in the organism. PMID- 27707931 TI - Phosphorylation Requirement of Murine Leukemia Virus p12. AB - : The p12 protein of murine leukemia virus (MLV) Gag is associated with the preintegration complex (PIC), and mutants of p12 (PM14) exhibit defects in nuclear entry/retention. Mutants of the phosphorylated serine 61 also have been reported to have defects in the early life cycle. Here we show that a phosphorylated peptide motif derived from human papillomavirus 8 (HPV-8), the E2 hinge region including residues 240 to 255, can functionally replace the main phosphorylated motif of MLV p12 and can rescue the viral titer of a strain with the lethal p12-PM14 mutation. Complementation with the HPV-8 E2 hinge motif generated multiple second-site mutations in live viral passage assays. Additional p12 phosphorylation sites were detected, including the late domain of p12 (PPPY) as well as the late domain/protease cleavage site of matrix (LYPAL), by mass spectrometry and Western blotting. Chromatin binding of p12-green fluorescent protein (GFP) fusion protein and functional complementation of p12-PM14 occurred in a manner independent of the E2 hinge region phosphorylation. Replacement of serine 61 by alanine within the minimal tethering domain (61SPMASRLRGRR71) maintained tethering, but in the context of the full-length p12, mutants with substitutions in S61 remained untethered and lost infectivity, indicating phosphorylation of p12 serine 61 functions to temporally regulate early and late p12 functions. IMPORTANCE: The p12 protein, required for both early and late viral functions, is the predominant phosphorylated viral protein of Moloney MLV and is required for virus viability. Our studies indicate that the N terminus of p12 represses the early function of the chromatin binding domain and that deletion of the N terminus activates chromatin binding in the wild-type Moloney MLV p12 protein. Mass spectrometry and mutagenesis studies suggest that phosphorylation of both the repression domain and the chromatin binding domain acts to temporally regulate this process at the appropriate stages during infection. PMID- 27707933 TI - Batterer Intervention Programs in Spain: An Analysis of Their Effectiveness. AB - Intimate partner violence against women is a social and women's health concern. Much effort has gone into providing services and support for victims of this violence. By contrast, intervention programs focusing on the batterers themselves have received far less attention. The purpose of this article is to provide a systematic review of the evidence regarding the effectiveness of batterer intervention programs (BIPs) implemented in Spain as provided by research published in peer-reviewed journals and scientific reports. The results obtained show that assessment focuses mainly on evaluating whether there is an improvement in the psychological variables of abusers. In cases where the rate of success or failure is analyzed, it is important to note the high drop-out rates observed, and the wide variability in success and improvement rates obtained. In summary, the results obtained in this revision allow to corroborate the assumption that associated with BIP is a lot of controversy, since its construction, its implementation, its assessment, and its effectiveness. PMID- 27707934 TI - Beyond the Walls: The Social Reintegration of Prisoners Through the Dialogic Reading of Classic Universal Literature in Prison. AB - This study analyzed whether it was possible to successfully transfer an experience of dialogic literary gatherings (DLGs) developed in a prison in the Basque Country (Spain), which was found to enhance the participants' readiness to return to their communities. A case study was conducted in a different prison in Catalonia that comprised interviews and focus groups with a group of female prisoners and volunteers involved in the DLG. The communicative analysis conducted showed that the replication of the DLG allowed the participants to discuss and reflect on their biographies and their expected pathways upon release, thus opening possibilities for personal and social change. The results show that participants perceived the DLG as a helpful resource for social reintegration and suggest that DLGs can be transferred to different correctional institutions. PMID- 27707932 TI - Deep Sequencing of Influenza A Virus from a Human Challenge Study Reveals a Selective Bottleneck and Only Limited Intrahost Genetic Diversification. AB - : Knowledge of influenza virus evolution at the point of transmission and at the intrahost level remains limited, particularly for human hosts. Here, we analyze a unique viral data set of next-generation sequencing (NGS) samples generated from a human influenza challenge study wherein 17 healthy subjects were inoculated with cell- and egg-passaged virus. Nasal wash samples collected from 7 of these subjects were successfully deep sequenced. From these, we characterized changes in the subjects' viral populations during infection and identified differences between the virus in these samples and the viral stock used to inoculate the subjects. We first calculated pairwise genetic distances between the subjects' nasal wash samples, the viral stock, and the influenza virus A/Wisconsin/67/2005 (H3N2) reference strain used to generate the stock virus. These distances revealed that considerable viral evolution occurred at various points in the human challenge study. Further quantitative analyses indicated that (i) the viral stock contained genetic variants that originated and likely were selected for during the passaging process, (ii) direct intranasal inoculation with the viral stock resulted in a selective bottleneck that reduced nonsynonymous genetic diversity in the viral hemagglutinin and nucleoprotein, and (iii) intrahost viral evolution continued over the course of infection. These intrahost evolutionary dynamics were dominated by purifying selection. Our findings indicate that rapid viral evolution can occur during acute influenza infection in otherwise healthy human hosts when the founding population size of the virus is large, as is the case with direct intranasal inoculation. IMPORTANCE: Influenza viruses circulating among humans are known to rapidly evolve over time. However, little is known about how influenza virus evolves across single transmission events and over the course of a single infection. To address these issues, we analyze influenza virus sequences from a human challenge experiment that initiated infection with a cell- and egg-passaged viral stock, which appeared to have adapted during its preparation. We find that the subjects' viral populations differ genetically from the viral stock, with subjects' viral populations having lower representation of the amino-acid-changing variants that arose during viral preparation. We also find that most of the viral evolution occurring over single infections is characterized by further decreases in the frequencies of these amino-acid-changing variants and that only limited intrahost genetic diversification through new mutations is apparent. Our findings indicate that influenza virus populations can undergo rapid genetic changes during acute human infections. PMID- 27707935 TI - How Does It Work? Mechanisms of Action in an In-Prison Restorative Justice Program. AB - Research is limited on mechanisms of action in restorative justice interventions. This multimethods study delineates the change processes underlying a successful in-prison group treatment program by (a) examining shifts in offenders' self schemas and (b) identifying key program components that influence this movement. Researchers assigned to small groups as "co-facilitators" gathered data using participant observation, semi-structured interviews, and psychological assessments at three time points. Mechanisms of action include group norms and behaviors that contrast with prior experiences and uncover offenders' self schemas through intrapsychic processes, which prompt them to test and act upon new possible selves through the group process. PMID- 27707936 TI - Liver glucose metabolism in humans. AB - Information about normal hepatic glucose metabolism may help to understand pathogenic mechanisms underlying obesity and diabetes mellitus. In addition, liver glucose metabolism is involved in glycosylation reactions and connected with fatty acid metabolism. The liver receives dietary carbohydrates directly from the intestine via the portal vein. Glucokinase phosphorylates glucose to glucose 6-phosphate inside the hepatocyte, ensuring that an adequate flow of glucose enters the cell to be metabolized. Glucose 6-phosphate may proceed to several metabolic pathways. During the post-prandial period, most glucose 6 phosphate is used to synthesize glycogen via the formation of glucose 1-phosphate and UDP-glucose. Minor amounts of UDP-glucose are used to form UDP-glucuronate and UDP-galactose, which are donors of monosaccharide units used in glycosylation. A second pathway of glucose 6-phosphate metabolism is the formation of fructose 6-phosphate, which may either start the hexosamine pathway to produce UDP-N-acetylglucosamine or follow the glycolytic pathway to generate pyruvate and then acetyl-CoA. Acetyl-CoA may enter the tricarboxylic acid (TCA) cycle to be oxidized or may be exported to the cytosol to synthesize fatty acids, when excess glucose is present within the hepatocyte. Finally, glucose 6 phosphate may produce NADPH and ribose 5-phosphate through the pentose phosphate pathway. Glucose metabolism supplies intermediates for glycosylation, a post translational modification of proteins and lipids that modulates their activity. Congenital deficiency of phosphoglucomutase (PGM)-1 and PGM-3 is associated with impaired glycosylation. In addition to metabolize carbohydrates, the liver produces glucose to be used by other tissues, from glycogen breakdown or from de novo synthesis using primarily lactate and alanine (gluconeogenesis). PMID- 27707937 TI - Effects of porcine MyD88 knockdown on the expression of TLR4 pathway-related genes and proinflammatory cytokines. AB - As a critical adapter protein in Toll-like receptor (TLR)/Interleukin (IL)-1R signalling pathway, myeloid differentiation protein 88 (MyD88) plays an important role in immune responses and host defence against pathogens. The present study was designed to provide a foundation and an important reagent for the mechanistic study of MyD88 and its role TLR/IL-1R signalling pathways in porcine immunity. Lentivirus-mediated RNAi was used to generate a porcine PK15 cell line with a silenced MyD88 gene and quantitative real-time PCR (qPCR) and Western blotting were used to detect changes in the expression of critical genes in the Toll-like receptor 4 (TLR4) signalling pathway. ELISA was used to measure the levels of seven proinflammatory cytokines-interleukin-1beta (IL-1beta), tumour necrosis factor-alpha (TNF-alpha), IL-6, IL-8, IL-12, macrophage inflammatory protein (MIP)-1alpha and MIP-1beta-in cell culture supernatants after MyD88 silencing. We successfully obtained a PK15 cell line with 61% MyD88 mRNA transcript down regulated. In PK15 cells with MyD88 silencing, the transcript levels of TLR4 and IL-1beta were significantly reduced, whereas there were no significant changes in the expression levels of cluster of differentiation antigen 14 (CD14), interferon alpha (IFN-alpha) or TNF-alpha The ELISA results showed that the levels of most cytokines were not significantly changed apart from IL-8 without stimulation, which was significantly up-regulated. When cells were induced by lipopolysaccharide (LPS) (0.1 MUg/ml) for 6 h, the global level of seven proinflammatory cytokines up-regulated and the level of IL-1beta, TNF-alpha, IL 6, IL-8 and IL-12 of Blank and negative control (NC) group up-regulated more significantly than RNAi group (P<0.05), which revealed that the MyD88 silencing could reduce the TLR4 signal transduction which inhibited the release of proinflammatory cytokines and finally leaded to immunosuppression. PMID- 27707939 TI - Comparative Genomic Analysis of Haemophilus haemolyticus and Nontypeable Haemophilus influenzae and a New Testing Scheme for Their Discrimination. AB - Haemophilus haemolyticus has been recently discovered to have the potential to cause invasive disease. It is closely related to nontypeable Haemophilus influenzae (NT H. influenzae). NT H. influenzae and H. haemolyticus are often misidentified because none of the existing tests targeting the known phenotypes of H. haemolyticus are able to specifically identify H. haemolyticus Through comparative genomic analysis of H. haemolyticus and NT H. influenzae, we identified genes unique to H. haemolyticus that can be used as targets for the identification of H. haemolyticus A real-time PCR targeting purT (encoding phosphoribosylglycinamide formyltransferase 2 in the purine synthesis pathway) was developed and evaluated. The lower limit of detection was 40 genomes/PCR; the sensitivity and specificity in detecting H. haemolyticus were 98.9% and 97%, respectively. To improve the discrimination of H. haemolyticus and NT H. influenzae, a testing scheme combining two targets (H. haemolyticus purT and H. influenzae hpd, encoding protein D lipoprotein) was also evaluated and showed 96.7% sensitivity and 98.2% specificity for the identification of H. haemolyticus and 92.8% sensitivity and 100% specificity for the identification of H. influenzae, respectively. The dual-target testing scheme can be used for the diagnosis and surveillance of infection and disease caused by H. haemolyticus and NT H. influenzae. PMID- 27707938 TI - Development and Evaluation of a Molecular Diagnostic Method for Rapid Detection of Histoplasma capsulatum var. farciminosum, the Causative Agent of Epizootic Lymphangitis, in Equine Clinical Samples. AB - Histoplasma capsulatum var. farciminosum, the causative agent of epizootic lymphangitis (EZL), is endemic in parts of Africa. Diagnosis based on clinical signs and microscopy lacks specificity and is a barrier to further understanding this neglected disease. Here, a nested PCR method targeting the internal transcribed spacer (ITS) region of the rRNA operon was validated for application to equine clinical samples. Twenty-nine horses with signs of EZL from different climatic regions of Ethiopia were clinically examined. Blood samples and aspirates of pus from cutaneous nodules were taken, along with blood from a further 20 horses with no cutaneous EZL lesions. Among the 29 horses with suspected cases of EZL, H. capsulatum var. farciminosum was confirmed by extraction of DNA from pus and blood samples from 25 and 17 horses, respectively. Positive PCR results were also obtained with heat-inactivated pus (24 horses) and blood (23 horses) spotted onto Whatman FTA cards. Two positive results were obtained among blood samples from 20 horses that did not exhibit clinical signs of EZL. These are the first reports of the direct detection of H. capsulatum var. farciminosum in equine blood and at high frequency among horses exhibiting cutaneous lesions. The nested PCR outperformed conventional microscopic diagnosis, as characteristic yeast cells could be observed only in 14 pus samples. The presence of H. capsulatum var. farciminosum DNA was confirmed by sequencing the cloned PCR products, and while alignment of the ITS amplicons showed very little sequence variation, there was preliminary single nucleotide polymorphism-based evidence for the existence of two subgroups of H. capsulatum var. farciminosum This molecular diagnostic method now permits investigation of the epidemiology of EZL. PMID- 27707940 TI - Chlorhexidine versus Tincture of Iodine for Reduction of Blood Culture Contamination Rates: a Prospective Randomized Crossover Study. AB - Blood cultures (BCs) are the standard method for diagnosis of bloodstream infections (BSIs). However, the average BC contamination rate (CR) in U.S. hospitals is 2.9%, potentially resulting in unnecessary antibiotic use and excessive therapy costs. Several studies have compared various skin antisepsis agents without a clear consensus as to which agent is most effective in reducing contamination. A prospective, randomized crossover study directly comparing blood culture contamination rates using chlorhexidine versus iodine tincture for skin antisepsis was performed at Robert Wood Johnson University Hospital (RWJUH). Eight nursing units at RWJUH were provided with blood culture kits containing either chlorhexidine (CH) or iodine tincture (IT) for skin antisepsis prior to all blood culture venipunctures, which were obtained by nurses or clinical care technicians. At quarterly intervals, the antiseptic agent used on each nursing unit was switched. Analyses of positive BCs were performed to distinguish true BSIs from contaminants. Of the 6,095 total BC sets obtained from the participating nursing units, 667 (10.94%) were positive and 238 (3.90%) were judged by the investigators to be contaminated. Of the 3,130 BCs obtained using IT, 340 (10.86%) were positive and 123 (3.93%) were contaminated. Of 2,965 BCs obtained using CH, 327 (11.03%) were positive and 115 (3.88%) were contaminated. The rates of contaminated BCs were not statistically significant between the two antiseptic agents (P = 1.0). We conclude that CH and IT are equivalent agents for blood culture skin antisepsis.

AB - In this study, a novel colloidal gold-based immunochromatographic strip (ICS) containing anti-Klebsiella pneumoniae capsular polysaccharide polyclonal antibodies was developed to specifically detect K. pneumoniae serotypes K1 and K2. Capsular polysaccharide K1 and K2 antigens were first used to produce polyclonal anti-K1 and anti-K2 antibodies. Reference strains with different serotypes, nontypeable K. pneumoniae strains, and other bacterial species were then used to assess the sensitivity and specificity of these test strips. The detection limit was found to be 105 CFU, and the ICSs were stable for 6 months when stored at room temperature. No false-positive or false-negative results were observed, and equivalent results were obtained compared to those of more conventional test methods, such as PCR or serum agglutination. In conclusion, the ICS developed here requires no technical expertise and allows for the specific, rapid, and simultaneous detection of K. pneumoniae serotypes K1 and K2.

AB - Currently, conventional enzyme immunoassays which use manual gold immunoassays and colloidal tests (GICTs) are used as screening tools to detect Treponema pallidum (syphilis), hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus type 1 (HIV-1), and HIV-2 in patients undergoing surgery. The present observational, cross-sectional study compared the sensitivity, specificity, and work flow characteristics of the conventional algorithm with manual GICTs with those of a newly proposed algorithm that uses the automated Bio Flash technology as a screening tool in patients undergoing gastrointestinal (GI) endoscopy. A total of 956 patients were examined for the presence of serological markers of infection with HIV-1/2, HCV, HBV, and T. pallidum The proposed algorithm with the Bio-Flash technology was superior for the detection of all markers (100.0% sensitivity and specificity for detection of anti-HIV and anti HCV antibodies, HBV surface antigen [HBsAg], and T. pallidum) compared with the conventional algorithm based on the manual method (80.0% sensitivity and 98.6% specificity for the detection of anti-HIV, 75.0% sensitivity for the detection of anti-HCV, 94.7% sensitivity for the detection of HBsAg, and 100% specificity for the detection of anti-HCV and HBsAg) in these patients. The automated Bio-Flash technology-based screening algorithm also reduced the operation time by 85.0% (205 min) per day, saving up to 24 h/week. In conclusion, the use of the newly proposed screening algorithm based on the automated Bio-Flash technology can provide an advantage over the use of conventional algorithms based on manual methods for screening for HIV, HBV, HCV, and syphilis before GI endoscopy.

AB - Toxic environmental effects of most insecticides have led to a search for bio organic insecticides. In this study, we tested the effects of lethal and sublethal exposure to two abamectin-based insecticides (VOLIAM TARGO and LUQ THOR) on survival, mating, and oviposition of the tephritid Anastrepha ludens (Loew). Different doses of insecticides (0.001-2.00% of the commercial products) were offered mixed with the phagostimulant bait Captor commonly used in spraying and in trapping activities for the control of flies. Both insecticides exhibited 90% killing effectiveness (Abbott index) when offered in doses between 0.02 to 2.00%. The LC50 obtained from the bioassay at 72 h after treatment was 0.003% of commercial product for TARGO and 0.008% for LUQ-THOR. Sublethal exposures to insecticides (0.003%; LC50 for TARGO and LC30 for LUQ-THOR) caused a reduction in oviposition but not in mating parameters, indicating that females were more susceptible than males to reduced doses of insecticide. The mean amount of eggs deposited 5 d after feeding on the insecticide-bait mixtures was reduced up to a third compared with the amount of eggs deposited by untreated females. Both insecticides are promising bio-organic alternatives to malathion in bait control programs against A. ludens. PMID- 27707943 TI - Action observation training of community ambulation for improving walking ability of patients with post-stroke hemiparesis: a randomized controlled pilot trial. AB - PURPOSE: To investigate the effects of action observation training involving community-based ambulation for improving walking ability after stroke. DESIGN: Randomized, controlled pilot study. SETTING: Inpatient rehabilitation hospital. SUBJECTS: A total of 25 inpatients with post-stroke hemiparesis were randomly assigned to either the experimental group ( n = 12) or control group ( n = 13). INTERVENTION: Subjects of the experimental group watched video clips demonstrating four-staged ambulation training with a more complex environment factor for 30 minutes, three times a week for four weeks. Meanwhile, subjects of the control group watched video clips, which showed different landscape pictures. MAIN MEASURES: Walking function was evaluated before and after the four-week intervention using a 10-m walk test, community walk test, activities-specific balance confidence scale, and spatiotemporal gait measures. RESULTS: Changes in the values for the 10-m walk test (0.17 +/-0.19 m/s vs. 0.05 +/-0.08 m/s), community walk test (-151.42 +/-123.82 seconds vs. 67.08 +/-176.77 seconds), and activities-specific balance confidence (6.25 +/-5.61 scores vs. 0.72 +/-2.24 scores) and the spatiotemporal parameters (i.e. stride length (19.00 +/-11.34 cm vs. 3.16 +/-11.20 cm), single support (5.87 +/-5.13% vs. 0.25 +/-5.95%), and velocity (15.66 +/-12.34 cm/s vs. 2.96 +/-10.54 cm/s)) indicated a significant improvement in the experimental group compared with the control group. In the experimental group, walking function and ambulation confidence was significantly different between the pre- and post-intervention, whereas the control group showed a significant difference only in the 10-m walk test. CONCLUSIONS: Action observation training of community ambulation may be favorably used for improving walking function of patients with post-stroke hemiparesis.

AB - Severe economic damage from citrus greening disease, caused by 'Candidatus Liberibacter asiaticus' bacteria, has stimulated development of methods to reduce mating and reproduction in populations of its insect vector, Diaphorina citri (Hemiptera: Liviidae). Male D. citri find mating partners by walking on host plants, intermittently producing vibrational calls that stimulate duetting replies by receptive females. The replies provide orientational feedback, assisting the search process. To test a hypothesis that D. citri mating can be disrupted using vibrational signals that compete with and/or mask female replies, courtship bioassays were conducted in citrus trees with or without interference from female reply mimics produced by a vibrating buzzer. Statistically significant reductions occurred in the rates and proportions of mating when the buzzer produced reply mimics within 0.4 s after male courtship calls compared with undisturbed controls. Observations of courtship behaviors in the two bioassays revealed activity patterns that likely contributed to the reductions. In both disruption and control tests, males reciprocated frequently between structural bifurcations and other transition points where signal amplitudes changed. Males in the disruption bioassay had to select among vibrational signals combined from the buzzer and the female at each transition point. They often turned towards the buzzer instead of the female. There was a statistically significant reduction in the proportion of males mating if they contacted the buzzer, possibly due to its higher vibration amplitude and duration in comparison with female replies. Potential applications of D. citri mating disruption technology in citrus groves are discussed. PMID- 27707946 TI - Impact of Citrus Thrips (Thysanoptera: Thripidae) on the Growth and Productivity of Southern Highbush Blueberries in California. AB - Citrus thrips, Scirtothrips citri (Moulton), is a foliage-feeding pest of blueberries in the San Joaquin Valley of California. We conducted a 4-yr field study to determine the type and amount of damage caused by this species. Using pesticides, we established gradients of citrus thrips in commercial blueberry fields near Richgrove, CA, in the fall of 2006, 2007, 2009, and 2014. Thrips densities were evaluated weekly for ~1 mo to determine cumulative thrips-days and correlate levels with the average length of new growth. During all four years of the study, there were significant negative correlations between thrips-days and shoot length (for every 100 thrips-days over a period of 4-5 wk there were reductions in the length of new shoot growth of 0.41 to 2.45 cm, 6.4-10.3%). During the spring following each trial, we evaluated the impact of thrips-days on blueberry yield and quality. During the 2006 trial, there was a significant negative correlation between thrips-days and yield as well as the number of berries per plant, but no yield effect was observed in the other three years of the study. No impacts on fruit quality were found any year. A discussion of the complexity of economic injury levels in blueberries is provided, especially considering that the cost of spraying for citrus thrips (estimated at US$150/ha) is almost irrelevant given crop values often in excess of US$100,000/ha. PMID- 27707947 TI - Residual and Systemic Efficacy of Chlorantraniliprole and Flubendiamide Against Corn Earworm (Lepidoptera: Noctuidae) in Soybean. AB - Experiments were conducted in Mississippi from 2013 to 2015 to determine the systemic and residual efficacy of chlorantraniliprole and flubendiamide against corn earworm, Helicoverpa zea (Boddie), in soybean. Both insecticides were applied at V4 and R3. Ten leaves that were present at the time of application and 10 newly emerged leaves that were not present at the time of application were collected to measure residual and systemic efficacy, respectively. Ten pods were removed from each plot at R5.5. For all assays, corn earworm larvae were placed on plant material. Chlorantraniliprole appeared to provide systemic control of H. zea, but was dependent on soybean growth stage at the time of application. In the V4 experiment, chlorantraniliprole resulted in greater mortality than the control on new leaves at 7 d after treatment, but not at 14 d. In the R3 experiment, chlorantraniliprole resulted in greater than 90% mortality on new leaves at all evaluation intervals. Mortality of H. zea on new leaves was <17% for flubendiamide and was not different than the control. Both insecticides resulted in significant mortality of H. zea on leaves that were present at the time of application for at least 31 d after application. Chlorantraniliprole resulted in greater mortality than flubendiamide at 24 and 31 d. Neither insecticide resulted in mortality of H. zea feeding on reproductive structures. These results suggest that chlorantraniliprole moves to new vegetative structures but not to reproductive structures of soybean, and that flubendiamide does not move systemically. PMID- 27707948 TI - D2R2: an evidence-based decision support tool to aid prioritisation of animal health issues for government funding. AB - An evidence-based decision support tool, 'D2R2', has been developed by Defra. It contains a wide range of standardised information about exotic and endemic diseases held in 'disease profiles'. Each profile includes 40 criteria used for scoring, enabling D2R2 to provide relative priority rankings for every disease profiled. D2R2 also provides a range of reports for each disease and the functionality to explore the impact of changes in any criterion or weighting on a disease's ranking. These outputs aid the prioritisation and management of animal diseases by government. D2R2 was developed with wide stakeholder engagement and its design was guided by clear specifications. It uses the weighted scores of a limited number of criteria to generate impact and risk scores for each disease, and relies on evidence drawn from published material wherever possible and maintained up to date. It allows efficient use of expertise, as maintained disease profiles reduce the need for on call, reactive, expert input for policy development and enables rapid simultaneous access to the same information by multiple parties, for example during exotic disease outbreaks. The experience in developing D2R2 has been shared internationally to assist others with their development of disease prioritisation and categorisation systems. PMID- 27707949 TI - The physical health of Indigenous and non-Indigenous patients participating in residential rehabilitation programs: a comparison study. AB - OBJECTIVE: To examine the differences in the physical health of Indigenous and non-Indigenous patients with severe mental illness (SMI) undergoing psychiatric rehabilitation. METHODS: An audit of the physical health of patients ( n = 361) in all publicly funded residential rehabilitation programs in Queensland was carried out in late 2014. Data collection focused on clinical and lifestyle factors associated with physical health. RESULTS: The prevalence of smoking, substance use and type 2 diabetes in Indigenous patients was significantly higher than rates found in non-Indigenous patients. Metabolic syndrome was also significantly higher in indigenous patients, with 66% of Indigenous patients compared to 46% of non-Indigenous patients meeting criteria for metabolic syndrome. CONCLUSIONS: Patients with SMI in residential rehabilitation programs have poor physical health. Our findings underscore the need for clinicians to develop and evaluate interventions aimed at improving the metabolic profile of those with SMI in residential rehabilitation programs. Historical factors and cultural traditions need to be considered when designing lifestyle interventions for Indigenous patients. PMID- 27707950 TI - Chronic headache with medication overuse: Long-term prognosis after withdrawal therapy. AB - Background Knowledge about long-term outcomes after medication withdrawal therapy for chronic headache, including tension type and migraine headache is lacking. Methods We re-examined 56 patients an average of nine years after they participated in a medication withdrawal study with a one-year follow-up. We collected and compared data on headache, use of medication, quality of life, quality of sleep, anxiety, depression, and labor participation one and nine years after the start of withdrawal therapy. Results Headache days per month decreased from 16.7 (14.0-19.3) at one year to 13.3 (10.6-15.9) at nine years (P = 0.007). The proportion of patients meeting the criteria for chronic headache decreased from 27/56 (48%) at one year to 18/56 (32%) at nine years (P = 0.004). Medication overuse was reported in seven (13%) patients at one year and 18 (32%) at nine years (P = 0.013). The majority of patients overusing medication at nine years (10/18) belonged to a group of 14 patients who had a poor early response to withdrawal therapy and had sustained chronic headache after nine years. After excluding patients receiving retirement pensions, the proportion who received disability benefits increased from 21/55 (38%) at one year to 30/49 (61%) at nine years (P = 0.003). Conclusion Improvements after withdrawal therapy for chronic headache last at least nine years, with a parallel increase in the use of disability benefits. However, a high proportion of patients with a poor initial response to withdrawal therapy and sustained chronic headache overuse medication. PMID- 27707951 TI - Different processing of meningeal and cutaneous pain information in the spinal trigeminal nucleus caudalis. AB - Introduction Within superficial trigeminal nucleus caudalis (Sp5C) (laminae I/II), meningeal primary afferents project exclusively to lamina I, whereas nociceptive cutaneous ones distribute in both lamina I and outer lamina II. Whether such a relative absence of meningeal inputs to lamina II represents a fundamental difference from cutaneous pathways in the central processing of sensory information is still unknown. Methods We recorded extracellular field potentials in the superficial Sp5C of anesthetised rats evoked by electrically stimulating the dura mater, to selectively assess the synaptic transmission between meningeal primary afferents and second-order Sp5C neurons, the first synapse in trigeminovascular pathways. We tested the effect of systemic morphine and local glycinergic and GABAAergic disinhibition. Results Meningeal stimulation evokes two negative field potentials in superficial Sp5C. The conduction velocities of the activated primary afferents are within the Adelta- and C-fibre ranges. Systemic morphine specifically suppresses meningeal C-fibre-evoked field potentials, and this effect is reversed by systemic naloxone. Segmental glycinergic or GABAAergic disinhibition strongly potentiates meningeal C-fibre evoked field potentials but not Adelta-fibre ones. Interestingly, the same segmental disinhibition conversely potentiates cutaneous Adelta-fibre-evoked field potentials and suppresses C-fibre ones. Conclusion These findings reveal that the different anatomical organization of meningeal and cutaneous inputs into superficial Sp5C is associated with a different central processing of meningeal and cutaneous pain information within Sp5C. Moreover, they suggest that the potentiation upon local disinhibition of the first synapse in trigeminovascular pathways may contribute to the generation of headache pain.

AB - Bacterial sexually transmitted infections including Chlamydia trachomatis and Neisseria gonorrhoeae remain an important public health concern. We aimed to assess the population-based incidence of C. trachomatis and N. gonorrhoeae in an age-standardized cohort over time. A retrospective study of a large Canadian health region was undertaken between 2010 and 2015 using linked census and digital laboratory data. C. trachomatis and N. gonorrhoeae tests were linked to patient data. Sex and age-standardized incidence rates (IR) and ratios (IRR) were calculated for cases and testing rates. The annual mean population was 1,150,556 individuals (50.1% female). A total of 15,109 cases of chlamydia and 981 cases of gonorrhoea occurred. The overall IR for chlamydia ranged from 18.81 to 25.63 cases per 10,000 person-years. The IRR was 1.27 (95% CI 1.20-1.34, p < 0.001) for the comparison of 2015 and 2010 rates. For gonorrhoea, overall rates ranged from 0.92 to 1.86 cases per 10,000 person-years. The IRR for gonorrhoea was 2.02 (95% CI 1.56-2.59, p < 0.001) for 2015 and 2010 rates. In our large population-based study spanning six years, we observed increasing rates of C. trachomatis and N. gonorrhoeae with low testing rates. PMID- 27707954 TI - Late HIV presentation - missed opportunities and factors associated with a changing pattern over time. AB - Delayed diagnosis of HIV infection has negative clinical, economic and public health implications. The study primary aim was to identify factors associated with late HIV presentation (Late Presenters [LPS], CD4 cell count < 350 cells/mm3). A secondary aim was to identify changing trends of late HIV presentation from 2002 to 2014 at our centre. A retrospective cohort study was performed. Demographic data and CD4 cell count of new HIV diagnoses presenting to our ambulatory HIV service over four time-periods from 2002 to 2014 were recorded. Proportion of LPS and factors associated with late presentation were compared using Graphpad Instat. In 2014, of 231 new patients attending for HIV care, 75 (32.6%) were late presenters versus 146 (66.4%) in 2002. This indicates a decreasing proportion of LPS from 2002 to 2014. However, the proportion of those with CD4 cell counts <200 on presentation at these two time intervals remain unchanged. The overall proportion of male LPS has increased over time and the proportion of LPS in the men who have sex with men (MSM) cohort has decreased over time, reflecting increased frequency of both HIV testing and diagnoses in MSM in recent years. The proportion of heterosexual LPS has not changed significantly in the same time period and LPS were older in 2014 versus 2002. The proportion of LPS defined by CD4 cell count remains higher than is justifiable in an era of increased HIV testing and awareness. Further targets for HIV testing to decrease rates of LPS include non-traditional risk groups including heterosexual and older patient cohorts. LPS rates are lower than rates found internationally, and it is possible that consensus definition of LPS needs to be revised. PMID- 27707956 TI - Dynamics of Base Excision Repair at the Maternal-Fetal Interface in Pregnancies Complicated by Preeclampsia. AB - Preeclampsia (PE) (gestational proteinuric hypertension) is the leading cause of maternal and perinatal mortality worldwide. Although placental endothelial dysfunction and oxidative stress are known to contribute to PE, the exact pathological basis for this disorder remains unclear. Previously, we demonstrated that DNA damage at the maternal-fetal interface is more common in the placentas of women with PE than normotensive controls. In this study, we utilized an in vivo comparative study, including 20 preeclamptic women and 8 healthy control subjects, and an in vitro hypoxia/reperfusion model to mimic the effects of oxidative stress at the maternal-fetal interface. We tracked the spatial pattern of expression of 2 base excision repair proteins, 8-oxoguanine glycosylase (OGG1) and apurinic/apyrimidinic endonuclease-1 (APE1), at the maternal-fetal interface in response to oxidative stress. In vivo, we found a significant increase in OGG1 and APE1 concentrations in PE placental tissues as compared to normotensive controls ( P < .0001). Further, our in vitro study revealed that OGG1 and APE1 expression is much greater in maternal cells (decidua) than in fetal cells (cytotrophoblasts) of placental tissue subjected to oxidative stress ( P < .0001). Our results suggest that OGG1 and APE1 likely protect decidual cells from oxidative base damage. PMID- 27707955 TI - Palliative long-term abdominal drains in refractory ascites due to end-stage liver disease: A case series. AB - BACKGROUND: Ascites, the commonest complication of cirrhosis, leads to frequent hospitalisations. Refractory ascites confers a median survival of 6 months without liver transplantation. In many, the management remains palliative (large volume paracentesis). Despite calls for improvement, palliative and end-of-life care is not yet integrated into end-stage liver disease. Long-term abdominal drains are a palliative strategy in malignant ascites, but not end-stage liver disease. CASE PRESENTATION: A retrospective, single centre, case series review was performed of patients undergoing long-term abdominal drain placement for refractory ascites secondary to end-stage liver disease at a large teaching hospital between August 2011 and March 2013. Case management: Patients with end stage liver disease and refractory ascites, where liver transplantation was not an option, were considered for long-term abdominal drains. Seven patients underwent successful long-term abdominal drain insertion after multi-professional assessment. Case outcome: Following long-term abdominal drain insertion, mean hospital attendances reduced to 1 (0-4) from 9 (4-21), with none for ascites management. Median survival after long-term abdominal drain insertion was 29 days (8-219). The complication rate was low and none life threatening. CONCLUSION: Palliative and end-of-life care needs in end-stage liver disease remain under addressed. Our data suggest that long-term abdominal drains may be a safe and effective palliative intervention in end-stage liver disease. Prospective randomised controlled trials comparing large-volume paracentesis versus long-term abdominal drains in refractory ascites secondary to end-stage liver disease are warranted. PMID- 27707957 TI - Preliminary study on Emodin alleviating alpha-naphthylisothiocyanate-induced intrahepatic cholestasis by regulation of liver farnesoid X receptor pathway. AB - The aim of this study is to investigate Emodin on alleviating intrahepatic cholestasis by regulation of liver farnesoid X receptor (FXR) pathway. Cell and animal models of intrahepatic cholestatis were established. Biochemical tests and histomorphology were performed. The messenger RNA (mRNA) and protein expression of FXR, small heterodimer partner (SHP), uridine diphosphate glucuronosyltransferase 2 family polypeptide B4 (UGT2B4), and bile salt export pump (BSEP) was detected. As a result, compared with the model group, the serum levels of biochemical test were significantly lower in the Emodin group (P <0.01). The histopathological changes were remitted significantly by Emodin treatment. In the model group, the mRNA and protein expression of FXR, SHP, UGT2B4, and BSEP was significantly lower than in the normal group in cell models (P <0.05). With Emodin intervention, the expression of FXR, SHP, UGT2B4, and BSEP was notably increased (P <0.05). In conclusion, Emodin plays a protective role in intrahepatic cholestasis by promoting FXR signal pathways.

PMID- 27707958 TI - A concise review on advances in development of small molecule anti-inflammatory therapeutics emphasising AMPK: An emerging target. AB - Inflammatory diseases are complex, multi-factorial outcomes of evolutionarily conserved tissue repair processes. For decades, non-steroidal anti-inflammatory drugs and cyclooxygenase inhibitors, the primary drugs of choice for the management of inflammatory diseases, addressed individual targets in the arachidonic acid pathway. Unsatisfactory safety and efficacy profiles of the above have necessitated the development of multi-target agents to treat complex inflammatory diseases. Current anti-inflammatory therapies still fall short of clinical needs and the clinical trial results of multi-target therapeutics are anticipated. Additionally, new drug targets are emerging with improved understanding of molecular mechanisms controlling the pathophysiology of inflammation. This review presents an outline of small molecules and drug targets in anti-inflammatory therapeutics with a summary of a newly identified target AMP activated protein kinase, which constitutes a novel therapeutic pathway in inflammatory pathology.

PMID- 27707960 TI - Drug-Induced Alterations of Endocannabinoid-Mediated Plasticity in Brain Reward Regions. AB - The endocannabinoid (eCB) system has emerged as one of the most important mediators of physiological and pathological reward-related synaptic plasticity. eCBs are retrograde messengers that provide feedback inhibition, resulting in the suppression of neurotransmitter release at both excitatory and inhibitory synapses, and they serve a critical role in the spatiotemporal regulation of both short- and long-term synaptic plasticity that supports adaptive learning of reward-motivated behaviors. However, mechanisms of eCB-mediated synaptic plasticity in reward areas of the brain are impaired following exposure to drugs of abuse. Because of this, it is theorized that maladaptive eCB signaling may contribute to the development and maintenance of addiction-related behavior. Here we review various forms of eCB-mediated synaptic plasticity present in regions of the brain involved in reward and reinforcement and explore the potential physiological relevance of maladaptive eCB signaling to addiction vulnerability. PMID- 27707963 TI - Disruption of Protein Processing in the Endoplasmic Reticulum of DYT1 Knock-in Mice Implicates Novel Pathways in Dystonia Pathogenesis. AB - : Dystonia type 1 (DYT1) is a dominantly inherited neurological disease caused by mutations in TOR1A, the gene encoding the endoplasmic reticulum (ER)-resident protein torsinA. Previous work mostly completed in cell-based systems suggests that mutant torsinA alters protein processing in the secretory pathway. We hypothesized that inducing ER stress in the mammalian brain in vivo would trigger or exacerbate mutant torsinA-induced dysfunction. To test this hypothesis, we crossed DYT1 knock-in with p58(IPK)-null mice. The ER co-chaperone p58(IPK) interacts with BiP and assists in protein maturation by helping to fold ER cargo. Its deletion increases the cellular sensitivity to ER stress. We found a lower generation of DYT1 knock-in/p58 knock-out mice than expected from this cross, suggesting a developmental interaction that influences viability. However, surviving animals did not exhibit abnormal motor function. Analysis of brain tissue uncovered dysregulation of eiF2alpha and Akt/mTOR translational control pathways in the DYT1 brain, a finding confirmed in a second rodent model and in human brain. Finally, an unbiased proteomic analysis identified relevant changes in the neuronal protein landscape suggesting abnormal ER protein metabolism and calcium dysregulation. Functional studies confirmed the interaction between the DYT1 genotype and neuronal calcium dynamics. Overall, these findings advance our knowledge on dystonia, linking translational control pathways and calcium physiology to dystonia pathogenesis and identifying potential new pharmacological targets. SIGNIFICANCE STATEMENT: Dystonia type 1 (DYT1) is one of the different forms of inherited dystonia, a neurological disorder characterized by involuntary, disabling movements. DYT1 is caused by mutations in the gene that encodes the endoplasmic reticulum (ER)-resident protein torsinA. How mutant torsinA causes neuronal dysfunction remains unknown. Here, we show the behavioral and molecular consequences of stressing the ER in DYT1 mice by increasing the amount of misfolded proteins. This resulted in the generation of a reduced number of animals, evidence of abnormal ER protein processing and dysregulation of translational control pathways. The work described here proposes a shared mechanism for different forms of dystonia, links for the first time known biological pathways to dystonia pathogenesis, and uncovers potential pharmacological targets for its treatment. PMID- 27707964 TI - Functional Subdomains within Scene-Selective Cortex: Parahippocampal Place Area, Retrosplenial Complex, and Occipital Place Area. AB - : Functional MRI studies suggest that at least three brain regions in human visual cortex-the parahippocampal place area (PPA), retrosplenial complex (RSC), and occipital place area (OPA; often called the transverse occipital sulcus) represent large-scale information in natural scenes. Tuning of voxels within each region is often assumed to be functionally homogeneous. To test this assumption, we recorded blood oxygenation level-dependent responses during passive viewing of complex natural movies. We then used a voxelwise modeling framework to estimate voxelwise category tuning profiles within each scene-selective region. In all three regions, cluster analysis of the voxelwise tuning profiles reveals two functional subdomains that differ primarily in their responses to animals, man made objects, social communication, and movement. Thus, the conventional functional definitions of the PPA, RSC, and OPA appear to be too coarse. One attractive hypothesis is that this consistent functional subdivision of scene selective regions is a reflection of an underlying anatomical organization into two separate processing streams, one selectively biased toward static stimuli and one biased toward dynamic stimuli. SIGNIFICANCE STATEMENT: Visual scene perception is a critical ability to survive in the real world. It is therefore reasonable to assume that the human brain contains neural circuitry selective for visual scenes. Here we show that responses in three scene-selective areas identified in previous studies-carry information about many object and action categories encountered in daily life. We identify two subregions in each area: one that is selective for categories of man-made objects, and another that is selective for vehicles and locomotion-related action categories that appear in dynamic scenes. This consistent functional subdivision may reflect an anatomical organization into two processing streams, one biased toward static stimuli and one biased toward dynamic stimuli. PMID- 27707966 TI - Neuregulin-Dependent Regulation of Fast-Spiking Interneuron Excitability Controls the Timing of the Critical Period. AB - : Maturation of excitatory drive onto fast-spiking interneurons (FS INs) in the visual cortex has been implicated in the control of the timing of the critical period for ocular dominance plasticity. However, the mechanisms that regulate the strength of these synapses over cortical development are not understood. Here we use a mouse model to show that neuregulin (NRG) and the receptor tyrosine kinase erbB4 regulate the timing of the critical period. NRG1 enhanced the strength of excitatory synapses onto FS INs, which inhibited ocular dominance plasticity during the critical period but rescued plasticity in transgenics with hypoexcitable FS INs. Blocking the effects of endogenous neuregulin via inhibition of erbBs rescued ocular dominance plasticity in postcritical period adults, allowing recovery from amblyopia induced by chronic monocular deprivation. Thus, the strength of excitation onto FS INs is a key determinant of critical period plasticity and is maintained at high levels by NRG-erbB4 signaling to constrain plasticity in adulthood. SIGNIFICANCE STATEMENT: Despite decades of experimentation, the mechanisms by which critical periods of enhanced synaptic plasticity are initiated and terminated are not completely understood. Here we show that neuregulin (NRG) and the receptor tyrosine kinase erbB4 determine critical period timing by controlling the strength of excitatory synapses onto FS INs. NRG1 enhanced excitatory drive onto fast spiking interneurons, which inhibited ocular dominance plasticity in juveniles but rescued plasticity in transgenics with hypoexcitable FS INs. Blocking the effects of endogenous neuregulin via inhibition of erbBs rescued ocular dominance plasticity in adults, allowing recovery from amblyopia induced by chronic monocular deprivation. Thus, in contrast to prevailing views of the termination of the critical period, active maintenance of strong excitation onto FS INs constrains plasticity in adults. PMID- 27707967 TI - Neuronal Dystroglycan Is Necessary for Formation and Maintenance of Functional CCK-Positive Basket Cell Terminals on Pyramidal Cells. AB - : Distinct types of GABAergic interneurons target different subcellular domains of pyramidal cells, thereby shaping pyramidal cell activity patterns. Whether the presynaptic heterogeneity of GABAergic innervation is mirrored by specific postsynaptic factors is largely unexplored. Here we show that dystroglycan, a protein responsible for the majority of congenital muscular dystrophies when dysfunctional, has a function at postsynaptic sites restricted to a subset of GABAergic interneurons. Conditional deletion of Dag1, encoding dystroglycan, in pyramidal cells caused loss of CCK-positive basket cell terminals in hippocampus and neocortex. PV-positive basket cell terminals were unaffected in mutant mice, demonstrating interneuron subtype-specific function of dystroglycan. Loss of dystroglycan in pyramidal cells had little influence on clustering of other GABAergic postsynaptic proteins and of glutamatergic synaptic proteins. CCK positive terminals were not established at P21 in the absence of dystroglycan and were markedly reduced when dystroglycan was ablated in adult mice, suggesting a role for dystroglycan in both formation and maintenance of CCK-positive terminals. The necessity of neuronal dystroglycan for functional innervation by CCK-positive basket cell axon terminals was confirmed by reduced frequency of inhibitory events in pyramidal cells of dystroglycan-deficient mice and further corroborated by the inefficiency of carbachol to increase IPSC frequency in these cells. Finally, neurexin binding seems dispensable for dystroglycan function because knock-in mice expressing binding-deficient T190M dystroglycan displayed normal CCK-positive terminals. Together, we describe a novel function of dystroglycan in interneuron subtype-specific trans-synaptic signaling, revealing correlation of presynaptic and postsynaptic molecular diversity. SIGNIFICANCE STATEMENT: Dystroglycan, an extracellular and transmembrane protein of the dystrophin-glycoprotein complex, is at the center of molecular studies of muscular dystrophies. Although its synaptic distribution in cortical brain regions is long established, function of dystroglycan in the synapse remained obscure. Using mice that selectively lack neuronal dystroglycan, we provide evidence that a subset of GABAergic interneurons requires dystroglycan for formation and maintenance of axonal terminals on pyramidal cells. As such, dystroglycan is the first postsynaptic GABAergic protein for which an interneuron terminal-specific function could be shown. Our findings also offer a new perspective on the mechanisms that lead to intellectual disability in muscular dystrophies without associated brain malformations. PMID- 27707965 TI - Basal Ganglia Output Controls Active Avoidance Behavior. AB - : Engrained avoidance behavior is highly adaptive when it keeps away harmful events and can be highly maladaptive when individuals elude harmless situations in anxiety disorders, but the neural circuits that mediate avoidance are poorly understood. Using DREADDs and optogenetics in mice, we show that the output of the basal ganglia through the substantia nigra pars reticulata (SNr) controls active avoidance. SNr excitation blocks avoidance to a conditioned sensory stimulus while preserving the ability to escape the harmful event. Conversely, SNr inhibition facilitates avoidance to the conditioned stimulus and suffices to drive avoidance without any conditioned sensory stimulus. The results highlight a midbrain circuit that gates avoidance responses, which can be targeted to ameliorate maladaptive avoidance in psychiatric disorders. SIGNIFICANCE STATEMENT: In many circumstances, subjects respond to fearful situations with avoidance. This is a useful coping strategy in situations in which there is impending danger. However, avoidance responses can also be maladaptive, as in anxiety disorders such as phobias (e.g., avoiding air transportation) and social anxiety (e.g., avoiding social situations). Despite the obvious clinical relevance, little is known about the neural circuits that mediate active avoidance. Using chemogenetics and optogenetics, we show that the output of the basal ganglia fully controls active avoidance behavior. PMID- 27707969 TI - Predictions Shape Confidence in Right Inferior Frontal Gyrus. AB - : It is clear that prior expectations shape perceptual decision-making, yet their contribution to the construction of subjective decision confidence remains largely unexplored. We recorded fMRI data while participants made perceptual decisions and confidence judgments, manipulating perceptual prior expectations while controlling for potential confounds of attention. Results show that subjective confidence increases as expectations increasingly support the decision, and that this relationship is associated with BOLD activity in right inferior frontal gyrus (rIFG). Specifically, rIFG is sensitive to the discrepancy between expectation and decision (mismatch), and higher mismatch responses are associated with lower decision confidence. Connectivity analyses revealed expectancy information to be represented in bilateral orbitofrontal cortex and sensory signals to be represented in intracalcarine sulcus. Together, our results indicate that predictive information is integrated into subjective confidence in rIFG, and reveal an occipital-frontal network that constructs confidence from top down and bottom-up signals. This interpretation was further supported by exploratory findings that the white matter density of right orbitofrontal cortex negatively predicted its respective contribution to the construction of confidence. Our findings advance our understanding of the neural basis of subjective perceptual processes by revealing an occipitofrontal functional network that integrates prior beliefs into the construction of confidence. SIGNIFICANCE STATEMENT: Perceptual decision-making is typically conceived as an integration of bottom-up and top-down influences. However, perceptual decisions are accompanied by a sense of confidence. Confidence is an important facet of perceptual consciousness yet remains poorly understood. Here we implicate right inferior frontal gyrus in constructing confidence from the discrepancy between perceptual judgment and its prior probability. Furthermore, we place right inferior frontal gyrus within an occipitofrontal network, consisting of orbitofrontal cortex and intracalcarine sulcus, which represents and communicates relevant top-down and bottom-up signals. Together, our data reveal a role of frontal regions in the top-down processes enabling perceptual decisions to become available for conscious report. PMID- 27707968 TI - Role of Prefrontal Cortex in Learning and Generalizing Hierarchical Rules in 8 Month-Old Infants. AB - : Recent research indicates that adults and infants spontaneously create and generalize hierarchical rule sets during incidental learning. Computational models and empirical data suggest that, in adults, this process is supported by circuits linking prefrontal cortex (PFC) with striatum and their modulation by dopamine, but the neural circuits supporting this form of learning in infants are largely unknown. We used near-infrared spectroscopy to record PFC activity in 8 month-old human infants during a simple audiovisual hierarchical-rule-learning task. Behavioral results confirmed that infants adopted hierarchical rule sets to learn and generalize spoken object-label mappings across different speaker contexts. Infants had increased activity over right dorsal lateral PFC when rule sets switched from one trial to the next, a neural marker related to updating rule sets into working memory in the adult literature. Infants' eye blink rate, a possible physiological correlate of striatal dopamine activity, also increased when rule sets switched from one trial to the next. Moreover, the increase in right dorsolateral PFC activity in conjunction with eye blink rate also predicted infants' generalization ability, providing exploratory evidence for frontostriatal involvement during learning. These findings provide evidence that PFC is involved in rudimentary hierarchical rule learning in 8-month-old infants, an ability that was previously thought to emerge later in life in concert with PFC maturation. SIGNIFICANCE STATEMENT: Hierarchical rule learning is a powerful learning mechanism that allows rules to be selected in a context-appropriate fashion and transferred or reused in novel contexts. Data from computational models and adults suggests that this learning mechanism is supported by dopamine innervated interactions between prefrontal cortex (PFC) and striatum. Here, we provide evidence that PFC also supports hierarchical rule learning during infancy, challenging the current dogma that PFC is an underdeveloped brain system until adolescence. These results add new insights into the neurobiological mechanisms available to support learning and generalization in very early postnatal life, providing evidence that PFC and the frontostriatal circuitry are involved in organizing learning and behavior earlier in life than previously known. PMID- 27707970 TI - A RET-ER81-NRG1 Signaling Pathway Drives the Development of Pacinian Corpuscles. AB - : Axon-Schwann cell interactions are crucial for the development, function, and repair of the peripheral nervous system, but mechanisms underlying communication between axons and nonmyelinating Schwann cells are unclear. Here, we show that ER81 is functionally required in a subset of mouse RET+ mechanosensory neurons for formation of Pacinian corpuscles, which are composed of a single myelinated axon and multiple layers of nonmyelinating Schwann cells, and Ret is required for the maintenance of Er81 expression. Interestingly, Er81 mutants have normal myelination but exhibit deficient interactions between axons and corpuscle forming nonmyelinating Schwann cells. Finally, ablating Neuregulin-1 (Nrg1) in mechanosensory neurons results in no Pacinian corpuscles, and an Nrg1 isoform not required for communication with myelinating Schwann cells is specifically decreased in Er81-null somatosensory neurons. Collectively, our results suggest that a RET-ER81-NRG1 signaling pathway promotes axon communication with nonmyelinating Schwann cells, and that neurons use distinct mechanisms to interact with different types of Schwann cells. SIGNIFICANCE STATEMENT: Communication between neurons and Schwann cells is critical for development, normal function, and regeneration of the peripheral nervous system. Despite many studies about axonal communication with myelinating Schwann cells, mostly via a specific isoform of Neuregulin1, the molecular nature of axonal communication with nonmyelinating Schwann cells is poorly understood. Here, we described a RET ER81-Neuregulin1 signaling pathway in neurons innervating Pacinian corpuscle somatosensory end organs, which is essential for communication between the innervating axon and the end organ nonmyelinating Schwann cells. We also showed that this signaling pathway uses isoforms of Neuregulin1 that are not involved in myelination, providing evidence that neurons use different isoforms of Neuregulin1 to interact with different types of Schwann cells. PMID- 27707971 TI - Thyroid Hormone Acts Locally to Increase Neurogenesis, Neuronal Differentiation, and Dendritic Arbor Elaboration in the Tadpole Visual System. AB - : Thyroid hormone (TH) regulates many cellular events underlying perinatal brain development in vertebrates. Whether and how TH regulates brain development when neural circuits are first forming is less clear. Furthermore, although the molecular mechanisms that impose spatiotemporal constraints on TH action in the brain have been described, the effects of local TH signaling are poorly understood. We determined the effects of manipulating TH signaling on development of the optic tectum in stage 46-49 Xenopus laevis tadpoles. Global TH treatment caused large-scale morphological effects in tadpoles, including changes in brain morphology and increased tectal cell proliferation. Either increasing or decreasing endogenous TH signaling in tectum, by combining targeted DIO3 knockdown and methimazole, led to corresponding changes in tectal cell proliferation. Local increases in TH, accomplished by injecting suspensions of tri-iodothyronine (T3) in coconut oil into the midbrain ventricle or into the eye, selectively increased tectal or retinal cell proliferation, respectively. In vivo time-lapse imaging demonstrated that local TH first increased tectal progenitor cell proliferation, expanding the progenitor pool, and subsequently increased neuronal differentiation. Local T3 also dramatically increased dendritic arbor growth in neurons that had already reached a growth plateau. The time-lapse data indicate that the same cells are differentially sensitive to T3 at different time points. Finally, TH increased expression of genes pertaining to proliferation and neuronal differentiation. These experiments indicate that endogenous TH locally regulates neurogenesis at developmental stages relevant to circuit assembly by affecting cell proliferation and differentiation and by acting on neurons to increase dendritic arbor elaboration. SIGNIFICANCE STATEMENT: Thyroid hormone (TH) is a critical regulator of perinatal brain development in vertebrates. Abnormal TH signaling in early pregnancy is associated with significant cognitive deficits in humans; however, it is difficult to probe the function of TH in early brain development in mammals because of the inaccessibility of the fetal brain in the uterine environment and the challenge of disambiguating maternal versus fetal contributions of TH. The external development of tadpoles allows manipulation and direct observation of the molecular and cellular mechanisms underlying TH's effects on brain development in ways not possible in mammals. We find that endogenous TH locally regulates neurogenesis at developmental stages relevant to circuit assembly by affecting neural progenitor cell proliferation and differentiation and by acting on neurons to enhance dendritic arbor elaboration. PMID- 27707972 TI - Methamphetamine Regulation of Firing Activity of Dopamine Neurons. AB - : Methamphetamine (METH) is a substrate for the dopamine transporter that increases extracellular dopamine levels by competing with dopamine uptake and increasing reverse transport of dopamine via the transporter. METH has also been shown to alter the excitability of dopamine neurons. The mechanism of METH regulation of the intrinsic firing behaviors of dopamine neurons is less understood. Here we identified an unexpected and unique property of METH on the regulation of firing activity of mouse dopamine neurons. METH produced a transient augmentation of spontaneous spike activity of midbrain dopamine neurons that was followed by a progressive reduction of spontaneous spike activity. Inspection of action potential morphology revealed that METH increased the half width and produced larger coefficients of variation of the interspike interval, suggesting that METH exposure affected the activity of voltage-dependent potassium channels in these neurons. Since METH has been shown to affect Ca2+ homeostasis, the unexpected findings that METH broadened the action potential and decreased the amplitude of afterhyperpolarization led us to ask whether METH alters the activity of Ca2+-activated potassium (BK) channels. First, we identified BK channels in dopamine neurons by their voltage dependence and their response to a BK channel blocker or opener. While METH suppressed the amplitude of BK channel-mediated unitary currents, the BK channel opener NS1619 attenuated the effects of METH on action potential broadening, afterhyperpolarization repression, and spontaneous spike activity reduction. Live-cell total internal reflection fluorescence microscopy, electrophysiology, and biochemical analysis suggest METH exposure decreased the activity of BK channels by decreasing BK alpha subunit levels at the plasma membrane. SIGNIFICANCE STATEMENT: Methamphetamine (METH) competes with dopamine uptake, increases dopamine efflux via the dopamine transporter, and affects the excitability of dopamine neurons. Here, we identified an unexpected property of METH on dopamine neuron firing activity. METH transiently increased the spontaneous spike activity of dopamine neurons followed by a progressive reduction of the spontaneous spike activity. METH broadened the action potentials, increased coefficients of variation of the interspike interval, and decreased the amplitude of afterhyperpolarization, which are consistent with changes in the activity of Ca2+-activated potassium (BK) channels. We found that METH decreased the activity of BK channels by stimulating BK-alpha subunit trafficking. Thus, METH modulation of dopamine neurotransmission and resulting behavioral responses is, in part, due to METH regulation of BK channel activity. PMID- 27707973 TI - T394A Mutation at the MU Opioid Receptor Blocks Opioid Tolerance and Increases Vulnerability to Heroin Self-Administration in Mice. AB - : The etiology and pathophysiology underlying opioid tolerance and dependence are still unknown. Because mu opioid receptor (MOR) plays an essential role in opioid action, many vulnerability-related studies have focused on single nucleotide polymorphisms of MOR, particularly on A118G. In this study, we found that a single-point mutation at the MOR T394 phosphorylation site could be another important susceptive factor in the development of opioid tolerance and dependence in mice. T394A mutation, in which a threonine at 394 was replaced by an alanine, did not alter agonist binding to MOR and opioid analgesia, but resulted in loss of etorphine-induced MOR internalization in spinal dorsal horn neurons and opioid analgesic tolerance induced by either morphine or etorphine. In addition, this mutation also caused an increase in intravenous heroin self-administration and in nucleus accumbens dopamine response to heroin. These findings suggest that T394 phosphorylation following MOR activation causes MOR internalization and desensitization, which subsequently contributes to the development of tolerance in both opioid analgesia and opioid reward. Accordingly, T394A mutation blocks opioid tolerance and leads to an increase in brain dopamine response to opioids and in opioid-taking behavior. Thus, the T394 may serve as a new drug target for modulating opioid tolerance and the development of opioid abuse and addiction. SIGNIFICANCE STATEMENT: The mechanisms underlying opioid tolerance and susceptibility to opioid addiction remain unclear. The present studies demonstrate that a single-point mutation at the T394 phosphorylation site in the C-terminal of mu opioid receptor (MOR) results in loss of opioid tolerance and enhanced vulnerability to heroin self-administration. These findings suggest that modulation of the MOR-T394 phosphorylation or dephosphorylation status may have therapeutic potential in management of pain, opioid tolerance, and opioid abuse and addiction. Accordingly, MOR-T394 mutation or polymorphisms could be a risk factor in developing opioid abuse and addiction and therefore be used as a new biomarker in prediction and prevention of opioid abuse and addiction. PMID- 27707974 TI - Glutamate Clearance Is Locally Modulated by Presynaptic Neuronal Activity in the Cerebral Cortex. AB - : Excitatory amino acid transporters (EAATs) are abundantly expressed by astrocytes, rapidly remove glutamate from the extracellular environment, and restrict the temporal and spatial extent of glutamate signaling. Studies probing EAAT function suggest that their capacity to remove glutamate is large and does not saturate, even with substantial glutamate challenges. In contrast, we report that neuronal activity rapidly and reversibly modulates EAAT-dependent glutamate transport. To date, no physiological manipulation has shown changes in functional glutamate uptake in a nonpathological state. Using iGluSnFr-based glutamate imaging and electrophysiology in the adult mouse cortex, we show that glutamate uptake is slowed up to threefold following bursts of neuronal activity. The slowing of glutamate uptake depends on the frequency and duration of presynaptic neuronal activity but is independent of the amount of glutamate released. The modulation of glutamate uptake is brief, returning to normal within 50 ms after stimulation ceases. Interestingly, the slowing of glutamate uptake is specific to activated synapses, even within the domain of an individual astrocyte. Activity induced slowing of glutamate uptake, and the increased persistence of glutamate in the extracellular space, is reflected by increased decay times of neuronal NR2A-mediated NMDA currents. These results show that astrocytic clearance of extracellular glutamate is slowed in a temporally and spatially specific manner following bursts of neuronal activity >=30 Hz and that these changes affect the neuronal response to released glutamate. This suggests a previously unreported form of neuron-astrocyte interaction. SIGNIFICANCE STATEMENT: We report the first fast, physiological modulation of astrocyte glutamate clearance kinetics. We show that presynaptic activity in the cerebral cortex increases the persistence of glutamate in the extracellular space by slowing its clearance by astrocytes. Because of abundant EAAT expression, glutamate clearance from the extracellular space has been thought to have invariant kinetics. While multiple studies report experimental manipulations resulting in altered EAAT expression, our findings show that astrocytic glutamate uptake is dynamic on a fast time-scale. This shows rapid plasticity of glutamate clearance, which locally modulates synaptic signaling in the cortex. As astrocytic glutamate uptake is a fundamental and essential mechanism for neurotransmission, this work has implications for neurotransmission, extrasynaptic receptor activation, and synaptic plasticity. PMID- 27707977 TI - Engagement of the Rat Hindlimb Motor Cortex across Natural Locomotor Behaviors. AB - : Contrary to cats and primates, cortical contribution to hindlimb locomotor movements is not critical in rats. However, the importance of the motor cortex to regain locomotion after neurological disorders in rats suggests that cortical engagement in hindlimb motor control may depend on the behavioral context. To investigate this possibility, we recorded whole-body kinematics, muscle synergies, and hindlimb motor cortex modulation in freely moving rats performing a range of natural locomotor procedures. We found that the activation of hindlimb motor cortex preceded gait initiation. During overground locomotion, the motor cortex exhibited consistent neuronal population responses that were synchronized with the spatiotemporal activation of hindlimb motoneurons. Behaviors requiring enhanced muscle activity or skilled paw placement correlated with substantial adjustment in neuronal population responses. In contrast, all rats exhibited a reduction of cortical activity during more automated behavior, such as stepping on a treadmill. Despite the facultative role of the motor cortex in the production of locomotion in rats, these results show that the encoding of hindlimb features in motor cortex dynamics is comparable in rats and cats. However, the extent of motor cortex modulations appears linked to the degree of volitional engagement and complexity of the task, reemphasizing the importance of goal-directed behaviors for motor control studies, rehabilitation, and neuroprosthetics. SIGNIFICANCE STATEMENT: We mapped the neuronal population responses in the hindlimb motor cortex to hindlimb kinematics and hindlimb muscle synergies across a spectrum of natural locomotion behaviors. Robust task-specific neuronal population responses revealed that the rat motor cortex displays similar modulation as other mammals during locomotion. However, the reduced motor cortex activity during more automated behaviors suggests a relationship between the degree of engagement and task complexity. This relationship emphasizes the importance of the behavioral procedure to engage the motor cortex during motor control studies, gait rehabilitation, and locomotor neuroprosthetic developments in rats. PMID- 27707976 TI - Proliferation and Survival of Embryonic Sympathetic Neuroblasts by MYCN and Activated ALK Signaling. AB - : Neuroblastoma (NB) is a childhood tumor that arises from the sympathoadrenal lineage. MYCN amplification is the most reliable marker for poor prognosis and MYCN overexpression in embryonic mouse sympathetic ganglia results in NB-like tumors. MYCN cooperates with mutational activation of anaplastic lymphoma kinase (ALK), which promotes progression to NB, but the role of MYCN and ALK in tumorigenesis is still poorly understood. Here, we use chick sympathetic neuroblasts to examine the normal function of MYCN and MYC in the control of neuroblast proliferation, as well as effects of overexpression of MYCN, MYC, and activated ALK, alone and in combination. We demonstrate that MYC is more strongly expressed than MYCN during neurogenesis and is important for in vitro neuroblast proliferation. MYC and MYCN overexpression elicits increased proliferation but does not sustain neuroblast survival. Unexpectedly, long-term expression of activated ALKF1174L leads to cell-cycle arrest and promotes differentiation and survival of postmitotic neurons. ALKF1174L induces NEFM, RET, and VACHT and results in decreased expression of proapototic (BMF, BIM), adrenergic (TH), and cell-cycle genes (e.g., CDC25A, CDK1). In contrast, neuroblast proliferation is maintained when MYCN and ALKF1174L are coexpressed. Proliferating MYCN/ALKF1174L neuroblasts display a differentiated phenotype but differ from ALK-expressing neurons by the upregulation of SKP2, CCNA2, E2F8, and DKC1 Inhibition of the ubiquitin ligase SKP2 (S-phase kinase-associated protein 2), which targets the CDK inhibitor p27 for degradation, reduces neuroblast proliferation, implicating SKP2 in the maintained proliferation of MYCN/ALKF1174L neuroblasts. Together, our results characterize MYCN/ALK cooperation leading to neuroblast proliferation and survival that may represent initial steps toward NB development. SIGNIFICANCE STATEMENT: MYCN overexpression combined with activated anaplastic lymphoma kinase (ALK) is sufficient to induce neuroblastoma (NB) in mouse sympathoadrenal cells. To address cellular and molecular effects elicited by MYCN/ALK cooperation, we used cultures of chick sympathetic neuroblasts. We demonstrate that MYCN increases proliferation but not survival, whereas long-term expression of ALKF1174L elicits cell-cycle exit, differentiation, and survival of postmitotic neurons. Combined MYCN/ALKF1174L expression allows long-term proliferation and survival of neuroblasts with differentiated characteristics. In the presence of ALKF1174L signaling, MYCN induces the expression of the ubiquitin ligase SKP2 (S phase kinase-associated protein 2), which targets p27 for degradation and is also upregulated in high-risk NB. SKP2 inhibition supports a function for SKP2 in the maintained neuroblast proliferation downstream of MYCN/ALK, which may represent an early step toward tumorigenesis. PMID- 27707975 TI - Effect of Ovarian Hormone Therapy on Cognition in the Aged Female Rhesus Macaque. AB - : Studies of the effect of hormone therapy on cognitive function in menopausal women have been equivocal, in part due to differences in the type and timing of hormone treatment. Here we cognitively tested aged female rhesus macaques on (1) the delayed response task of spatial working memory, (2) a visuospatial attention task that measured spatially and temporally cued reaction times, and (3) a simple reaction time task as a control for motor speed. After task acquisition, animals were ovariectomized (OVX). Their performance was compared with intact controls for 2 months, at which time no group differences were found. The OVX animals were then assigned to treatment with either a subcutaneous sham implant (OVX), 17-beta estradiol (E) implant (OVX+E) or E implant plus cyclic oral progesterone (OVX+EP). All groups were then tested repeatedly over 12 months. The OVX+E animals performed significantly better on the delayed response task than all of the other groups for much of the 12 month testing period. The OVX+EP animals also showed improved performance in the delayed response task, but only at 30 s delays and with performance levels below that of OVX+E animals. The OVX+E animals also performed significantly better in the visuospatial attention task, particularly in the most challenging invalid cue condition; this difference also was maintained across the 12 month testing period. Simple reaction time was not affected by hormonal manipulation. These data demonstrate that chronic, continuous administration of E can exert multiple beneficial cognitive effects in aged, OVX rhesus macaque females. SIGNIFICANCE STATEMENT: Hormone therapy after menopause is controversial. We tested the effects of hormone replacement in aged rhesus macaques, soon after surgically-induced menopause [ovariectomy (OVX)], on tests of memory and attention. Untreated ovarian-intact and OVX animals were compared with OVX animals receiving estradiol (E) alone or E with progesterone (P). E was administered in a continuous fashion via subcutaneous implant, whereas P was administered orally in a cyclic fashion. On both tests, E-treated animals performed better than the other 3 experimental groups across 1 year of treatment. Thus, in this monkey model, chronic E administered soon after the loss of ovarian hormones had long-term benefits for cognitive function. PMID- 27707979 TI - APOE-Sensitive Cholinergic Sprouting Compensates for Hippocampal Dysfunctions Due to Reduced Entorhinal Input. AB - : Brain mechanisms compensating for cerebral lesions may mitigate the progression of chronic neurodegenerative disorders such as Alzheimer's disease (AD). Mild cognitive impairment (MCI), which often precedes AD, is characterized by neuronal loss in the entorhinal cortex (EC). This loss leads to a hippocampal disconnection syndrome that drives clinical progression. The concomitant sprouting of cholinergic terminals in the hippocampus has been proposed to compensate for reduced EC glutamatergic input. However, in absence of direct experimental evidence, the compensatory nature of the cholinergic sprouting and its putative mechanisms remain elusive. Transgenic mice expressing the human APOE4 allele, the main genetic risk factor for sporadic MCI/AD, display impaired cholinergic sprouting after EC lesion. Using these mice as a tool to manipulate cholinergic sprouting in a disease-relevant way, we showed that this sprouting was necessary and sufficient for the acute compensation of EC lesion-induced spatial memory deficit before a slower glutamatergic reinnervation took place. We also found that partial EC lesion generates abnormal hyperactivity in EC/dentate networks. Dentate hyperactivity was abolished by optogenetic stimulation of cholinergic fibers. Therefore, control of dentate hyperactivity by cholinergic sprouting may be involved in functional compensation after entorhinal lesion. Our results also suggest that dentate hyperactivity in MCI patients may be directly related to EC neuronal loss. Impaired sprouting during the MCI stage may contribute to the faster cognitive decline reported in APOE4 carriers. Beyond the amyloid contribution, the potential role of both cholinergic sprouting and dentate hyperactivity in AD symptomatogenesis should be considered in designing new therapeutic approaches. SIGNIFICANCE STATEMENT: Currently, curative treatment trials for Alzheimer's disease (AD) have failed. The endogenous ability of the brain to cope with neuronal loss probably represents one of the most promising therapeutic targets, but the underlying mechanisms are still unclear. Here, we show that the mammalian brain is able to manage several deleterious consequences of the loss of entorhinal neurons on hippocampal activity and cognitive performance through a fast cholinergic sprouting followed by a slower glutamatergic reinnervation. The cholinergic sprouting is gender dependent and highly sensitive to the genetic risk factor APOE4 Our findings highlight the specific impact of early loss of entorhinal input on hippocampal hyperactivity and cognitive deficits characterizing early stages of AD, especially in APOE4 carriers. PMID- 27707980 TI - Persistent right ventricular dysfunction, functional capacity limitation, exercise intolerance, and quality of life impairment following pulmonary embolism: Systematic review with meta-analysis. AB - Long-term right ventricular (RV) function, functional capacity, exercise capacity, and quality of life following pulmonary embolism (PE), and the impact of thrombolysis, are unclear. A systematic review of studies that evaluated these outcomes with ? 3-month mean follow-up after PE diagnosis was performed. For each outcome, random effects meta-analyses were performed. Twenty-six studies (3671 patients) with 18-month median follow-up were included. The pooled prevalence of RV dysfunction was 18.1%. Patients treated with thrombolysis had a lower, but not statistically significant, risk of RV dysfunction versus those treated with anticoagulation (odds ratio: 0.51, 95% CI: 0.24 to 1.13, p=0.10). Pooled prevalence of at least mild functional impairment (NYHA II-IV) was 33.2%, and at least moderate functional impairment (NYHA III-IV) was 11.3%. Patients treated with thrombolysis had a lower, but not statistically significant, risk of at least moderate functional impairment versus those treated with anticoagulation (odds ratio: 0.48, 95% CI: 0.15 to 1.49, p=0.20). Pooled 6-minute walk distance was 415 m (95% CI: 372 to 458 m), SF-36 Physical Component Score was 44.8 (95% CI: 43 to 46), and Pulmonary Embolism Quality of Life (QoL) Questionnaire total score was 9.1. Main limitations included heterogeneity among studies for many outcomes, variation in the completeness of data reported, and inclusion of data from non-randomized, non-controlled, and retrospective studies. Persistent RV dysfunction, impaired functional status, diminished exercise capacity, and reduced QoL are common in PE survivors. The effect of thrombolysis on RV function and functional status remains unclear.

PMID- 27707978 TI - Impact of Visual Corticostriatal Loop Disruption on Neural Processing within the Parahippocampal Place Area. AB - : The caudate nucleus is a part of the visual corticostriatal loop (VCSL), receiving input from different visual areas and projecting back to the same cortical areas via globus pallidus, substantia nigra, and thalamus. Despite perceptual and navigation impairments in patients with VCSL disruption due to caudate atrophy (e.g., Huntington's disease, HD), the relevance of the caudate nucleus and VCSL on cortical visual processing is not fully understood. In a series of fMRI experiments, we found that the caudate showed a stronger functional connection to parahippocampal place area (PPA) compared with adjacent regions (e.g., fusiform face area, FFA) within the temporal visual cortex. Consistent with this functional link, the caudate showed a higher response to scenes compared with faces, similar to the PPA. Testing the impact of VCSL disruption on neural processes within PPA, HD patients showed reduced scene selective activity within PPA compared with healthy matched controls. In contrast, the level of selective activity in adjacent cortical and subcortical face-selective areas (i.e., FFA and amygdala) remained intact. These results show some of the first evidence for the direct impact and potential clinical significance of VCSL on the generation of "selective" activity within PPA. SIGNIFICANCE STATEMENT: Visual perception is often considered the product of a multistage feedforward neural processing between visual cortical areas, ignoring the likely impact of corticosubcortical loops on this process. Here, we provide evidence for the contribution of visual corticostriatal loop and the caudate nucleus on generating selective response within parahippocampal place area (PPA). Our results show that disruption of this loop in Huntington's disease patients reduces the level of selective activity within PPA, which may lead to related perceptual impairments in these patients. PMID- 27707982 TI - Assessment of Renal Injury in Patients Undergoing Elective EVAR Using Urinary Neutrophil Gelatin-Associated Lipocalin, Interleukin 18, and Retinol-Binding Protein. AB - Acute kidney injury (AKI) is a recognized complication post-endovascular aneurysm repair (EVAR). Neutrophil gelatin-associated lipocalin (NGAL), interleukin 18 (IL 18), and retinol-binding protein are emerging urinary biomarkers that have shown promise in detecting subclinical and clinical renal impairment. In this study, we assessed changes in these urinary biomarkers as well as serum creatinine (SCr) in patients undergoing EVAR. Urine samples were collected prospectively at 5 time points for each recruited patient: pre-EVAR (baseline) and 6, 12, 24, and 48 hours after the procedure for serial assessment of urinary biomarkers. Serum creatinine was quantified preoperatively and at 24 and 48 hours postoperatively. Serial changes of urinary biomarkers and SCr were assessed. A significant increase in NGAL and IL-18 from baseline was observed ( P < .05), as early as 6 hours for NGAL. A significant rise in levels of NGAL and IL-18 precedes the significant rise in SCr. These findings highlight the potential of emerging urinary biomarkers in detecting early AKI following EVAR.

AB - We report on the use of the Gravid Aedes Trap (GAT) as a surveillance device for Aedes albopictus (Skuse) relative to the BG-Sentinel (BGS) trap in field studies conducted in Trenton, NJ, and on Hammond Island, Queensland, Australia. A parallel study conducted in Nha Trang, Vietnam, assessed the use of the GAT as an indoor surveillance device as well as the use of canola oil as a noninsecticide killing agent. In Trenton and Hammond Island, the GAT collected fewer male (0.40 +/- 0.12 and 0.43 +/- 0.30, respectively) and female (3.05 +/- 0.67 and 2.7 +/- 2.3, respectively) Ae. albopictus than the BGS trap (males: 3.54 +/- 1.26 and 3.75 +/- 0.83; females: 4.66 +/- 1.18 and 3.9 +/- 0.23) over their respective sampling periods (i.e., 24 h for the BGS and 1 wk for the GAT). Despite differences in capture rates, the percentage of traps positive for female Ae. albopictus was similar between the BGS and GAT (Trenton: 60.1 +/- 6.3% and 64.4 +/- 4.1%; Hammond: 87.5 +/- 6.9% and 80.0 +/- 8.2%). In Nha Trang, the GAT was equally effective indoors and outdoors with (10 g hay or 3 g fish food) and without (water or empty) infusion. Additionally, no significant decrease in collections was observed between GATs set with canola oil or long-lasting insecticidal net. In summary, both traps were successful in monitoring female Ae. albopictus over their respective trapping intervals, but would be best used to complement each other to monitor both sexes and all physiological stages of female Ae. albopictus. However, the versatility and low-cost of the GAT makes it an attractive alternative to the more expensive BGS trap. PMID- 27707986 TI - Putative Sensory Structures Associated With the Food Canal of Tabanus atratus (Diptera: Tabanidae). AB - Putative sensory structures in the food canal, and distal vestibule region entering the canal of Tabanus atratus F., are described. Two pairs of sensilla were observed in the walls of the vestibule-a distal pair of the basiconic type, and a pair of setifiorm sensilla at the base of the vestibule. Vestibular sensilla were constant in type, number, and position. Conversely, setiform sensilla in right and left walls of the food canal varied in number from one fly specimen to another, and lacked evidence of pairing (i.e., sensilla in one wall did not necessarily have a counterpart in the other wall). Food canal sensilla were of setiform design, with the exception of a single basiconic sensilla in each lateral wall of the food canal in every fly. When the food canal was partitioned into four equidistant regions, setiform sensilla were aggregated in the two distal-most regions, with relatively few sensilla observed in the two proximal canal regions. This aggregation was significant, leading to rejection of the null hypothesis that setiform sensilla were evenly distribution throughout the length of the food canal. Basiconic sensilla were always located in the distal-most region of the food canal.

AB - OBJECTIVES: Previous studies have shown that mixed-strain gonococcal infections can occur. However, it remains unclear whether such infections impact upon the reliability of Neisseria gonorrhoeae antimicrobial resistance (AMR) surveillance. In this study, we aimed to resolve this question by intensively sampling isolates from gonorrhoea-positive specimens in a high-risk population in Sydney, Australia. METHODS: A total of 615 N. gonorrhoeae isolates, originating from 63 clinical samples (31 rectal swabs and 32 throat swabs), were characterized. All isolates were subject to N. gonorrhoeae identification, antimicrobial susceptibility testing and genotyping by SNP-based MLST. RESULTS: Only 2 of the 63 (3.2%) samples provided evidence of mixed-strain infections. These comprised two rectal swabs that harboured isolates of different SNP-based MLST genotypes; however, the AMR susceptibility profiles of the different genotypes from these samples were indistinguishable. Within-sample differences in the AMR susceptibility profiles were observed for a further seven samples; however, the differences were not considered significant; MIC values were typically within a 2 fold difference or were close to test breakpoints. CONCLUSIONS: Results of this study provide further evidence that mixed-strain gonococcal infections do occur, although at low prevalence. Our data indicate that at a population level such infections are unlikely to impact significantly upon N. gonorrhoeae AMR surveillance. PMID- 27707990 TI - Efficacy of ceftolozane/tazobactam against urinary tract and intra-abdominal infections caused by ESBL-producing Escherichia coli and Klebsiella pneumoniae: a pooled analysis of Phase 3 clinical trials. AB - OBJECTIVES: The increase in infections caused by drug-resistant ESBL-producing Enterobacteriaceae (ESBL-ENT) is a global concern. The characteristics and outcomes of patients infected with ESBL-ENT were examined in a pooled analysis of Phase 3 clinical trials of ceftolozane/tazobactam in patients with complicated urinary tract infections (ASPECT-cUTI) and complicated intra-abdominal infections (ASPECT-cIAI). METHODS: Trials were randomized and double blind. The ASPECT-cUTI regimen was 7 days of either intravenous ceftolozane/tazobactam (1.5 g) every 8 h or levofloxacin (750 mg) once daily. The ASPECT-cIAI regimen was 4-14 days of either intravenous ceftolozane/tazobactam (1.5 g) plus metronidazole (500 mg) or meropenem (1 g) every 8 h. Baseline cultures were obtained in both indications. Enterobacteriaceae were selected for ESBL characterization based on predefined criteria and were verified genotypically. Outcomes were assessed at the test-of cure visit 5-9 days post-therapy in ASPECT-cUTI and 24-32 days post-randomization in ASPECT-cIAI among microbiologically evaluable (ME) patients. RESULTS: Of 2076 patients randomized, 1346 were included in the pooled ME population and 150 of 1346 (11.1%) had ESBL-ENT at baseline. At US FDA/EUCAST breakpoints of <=2/<=1 mg/L, 81.8%/72.3% of ESBL-ENT (ESBL-Escherichia coli, 95%/88.1%; ESBL-Klebsiella pneumoniae, 56.7%/36.7%) were susceptible to ceftolozane/tazobactam versus 25.3%/24.1% susceptible to levofloxacin and 98.3%/98.3% susceptible to meropenem at CLSI/EUCAST breakpoints. Clinical cure rates for ME patients with ESBL-ENT were 97.4% (76/78) for ceftolozane/tazobactam [ESBL-E. coli, 98.0% (49 of 50); ESBL-K. pneumoniae, 94.4% (17 of 18)], 82.6% (38 of 46) for levofloxacin and 88.5% (23 of 26) for meropenem. CONCLUSIONS: Randomized trial data demonstrated high clinical cure rates with ceftolozane/tazobactam treatment of cIAI and cUTI caused by ESBL-ENT. PMID- 27707992 TI - In vitro 'time-to-kill' assay to assess the cidal activity dynamics of current reference drugs against Leishmania donovani and Leishmania infantum. AB - OBJECTIVES: Despite a continued search for novel antileishmanial drugs, treatment options remain restricted to a few standard drugs, e.g. antimonials, miltefosine, amphotericin B and paromomycin. Although these drugs have now been used for several decades, their mechanism of action still remains partly hypothetical and their dynamics of cidal action and time-to-kill are still poorly documented. METHODS: An in vitro time-to-kill assay on intracellular amastigotes of the laboratory reference strains Leishmania donovani (MHOM/ET/67/L82) and Leishmania infantum [MHOM/MA(BE)/67/ITMAP263] evaluated the cidal action dynamics of the listed reference drugs at three different concentrations: at IC50, 2 * IC50 and the near cytotoxic dose level (CC90: determined on MRC-5 cells). This assay focused on identifying the minimal exposure time needed to completely eliminate viable intracellular amastigotes, using the standard microscopic Giemsa assay and the promastigote back-transformation assay. RESULTS: While 100% reduction was microscopically apparent for most drugs, the promastigote back-transformation assay clearly demonstrated a concentration- and time-dependent cidal mechanism. The time-to-kill at 2 * IC50 was >=240 h for pentavalent antimony (77 MUg eq./mL), 96 h for trivalent antimony (44 MUg eq./mL), 168 to >240 h for miltefosine (10 MUM), 168 h for paromomycin (100 MUM) and >240 h for amphotericin B (2 MUM). No differences were noted between both Leishmania species. CONCLUSIONS: Evaluation of the concentration- and time-dependent cidal activity using the promastigote back-transformation assay revealed striking differences in efficacy of the different antileishmanial reference drugs. This assay should allow in-depth pharmacodynamic evaluation of novel drug leads in comparison with the existing antileishmanial drug repertoire. PMID- 27707994 TI - Testing multidimensional well-being among university community samples in Italy and Serbia. AB - Today well-being attracts the attention of public health professionals who are looking to explore life satisfaction as a whole and its specific domains. In order to contribute in moving the measurement of subjective well-being from a primarily academic activity to the sphere of intervention, we need to assess tools to measure multidimensional well-being (MWB) adopting state-of-the-art statistical techniques. Through structural equation modelling our goal was to test a MWB model among Italian and Serbian university students and to further observe its relationships with measures of life goals' pursuing. This cross sectional pilot study was conducted on a consecutive sample of 86 Italian (45% female; Mage = 24.20, SD = 2.02) and 83 Serbian (55% female; Mage = 23.52, SD = 2.48) university students. Participants filled in an anonymous questionnaire investigating: self-perceived MWB, standardized control measures of well-being (life satisfaction and eudaimonic well-being), and commitment and stress regarding personal goal pursuing. Results evidenced how Serbians reported higher scores on MWB and on control measures than Italians. Moreover, the most frequently reported goals were to complete studies, to obtain job position and to be healthy. Exploratory and multi-group confirmatory factor analyses yielded a one-factor solution of MWB across Italian and Serbian sub-groups. MWB resulted positively associated with standardized control measures in both national groups. The results support the strength of our MWB model applied to samples of young university students in Italy and Serbia. Based on such findings, future studies may adopt this instrument in larger populations of university students in these two countries. PMID- 27707995 TI - Glycogen: Multiple Roles in the CNS. AB - The historically neurocentric view of astrocytes as Styrofoam cushioning that rigidly clad neurons within the brain parenchyma has been superseded in the past 30 years by an increasing appreciation of the myriad roles astrocytes contribute to supporting physiological brain function. It is widely recognized that the continuous support provided by astrocytes, from prenatal development to maturity, is vital for neuronal function. Indeed, the numerous and diverse roles furnished by astrocytes contrasts with the vital but restricted transmission of action potentials that is the neuron's primary role. An emerging role for astrocytes is that of providing energy substrate in the form of glycogen-derived lactate to neurons. This role was established during periods of limited glucose availability but has been extended to encompass one of the most important physiological brain functions, learning and memory. In this context glycogen metabolism is integral to the consolidation of learning into long-term retention of memories, a process vital to the higher functioning of the human brain. PMID- 27707991 TI - Effect of diurnal variation, CYP2B6 genotype and age on the pharmacokinetics of nevirapine in African children. AB - OBJECTIVES: To characterize the effects of CYP2B6 polymorphisms, diurnal variation and demographic factors on nevirapine pharmacokinetics in African children. METHODS: Non-linear mixed-effects modelling conducted in NONMEM 7.3 described nevirapine plasma concentration-time data from 414 children aged 0.3-15 years. RESULTS: Nevirapine pharmacokinetics was best described using a one compartment disposition model with elimination through a well-stirred liver model accounting for a first-pass effect and transit-compartment absorption. Intrinsic clearance was affected by diurnal variation (characterized using a cosine function with peak amplitude 29% at 12 noon) and CYP2B6 metabolizer status [extensive metabolizer (EM) 516GG|983TT, reference; intermediate metabolizer (IM) 516GT|983TT or 516GG|983TC, 17% lower; slow metabolizer (SM) 516TT|983TT or 516GT|983TC, 50% lower; ultra-slow metabolizer (USM) 516GG|983CC, 68% lower]. Age was found to affect pre-hepatic bioavailability: 31.7% lower at birth and increasing exponentially. Median (90% CI) evening Cmin values in the different metabolizer groups were 5.01 (3.01-7.47), 6.55 (3.65-13.32), 11.59 (5.44-22.71) and 12.32 (12.32-27.25) mg/L, respectively. Evening Cmin values were <3 mg/L in 43% of EM weighing <6 kg and 26% of IM weighing <6 kg, while 73% of SM and 88% of USM in all weight-bands had evening Cmin values >8 mg/L. Cmin was not markedly affected by administration time, but was altered by unequal splitting of the daily dose. CONCLUSIONS: Diurnal variation does not greatly affect nevirapine exposure. However, when daily doses cannot be split equally, the larger dose should be given in the morning. To achieve homogeneous exposures, nevirapine doses for SM and USM should be reduced by 50%, and children weighing <6 kg with EM or IM metabolizer status should receive the same dose as children weighing 6 10 kg. PMID- 27707993 TI - Short- and long-term effects of oral vancomycin on the human intestinal microbiota. AB - BACKGROUND: Oral vancomycin remains the mainstay of therapy for severe infections produced by Clostridium difficile, the most prevalent cause of healthcare associated infectious diarrhoea in developed countries. However, its short- and long-term effects on the human intestinal microbiota remain largely unknown. METHODS: We utilized high-throughput sequencing to analyse the effects of vancomycin on the faecal human microbiota up to 22 weeks post-antibiotic cessation. The clinical relevance of the observed microbiota perturbations was studied in mice. RESULTS: During vancomycin therapy, most intestinal microbiota genera and operational taxonomic units (OTUs) were depleted in all analysed subjects, including all baseline OTUs from the phylum Bacteroidetes. This was accompanied by a vast expansion of genera associated with infections, including Klebsiella and Escherichia/Shigella. Following antibiotic cessation, marked differences in microbiota resilience were observed among subjects. While some individuals recovered a microbiota close to baseline composition, in others, up to 89% of abundant OTUs could no longer be detected. The clinical relevance of the observed microbiota changes was further demonstrated in mice, which developed analogous microbiota alterations. During vancomycin treatment, mice were highly susceptible to intestinal colonization by an antibiotic-resistant pathogen and, upon antibiotic cessation, a less-resilient microbiota allowed higher levels of pathogen colonization. CONCLUSIONS: Oral vancomycin induces drastic and consistent changes in the human intestinal microbiota. Upon vancomycin cessation, the microbiota recovery rate varied considerably among subjects, which could influence, as validated in mice, the level of susceptibility to pathogen intestinal colonization. Our results demonstrate the negative long-term effects of vancomycin, which should be considered as a fundamental aspect of the cost benefit equation for antibiotic prescription. PMID- 27707996 TI - Chemotaxis and Immunoregulatory Function of Cardiac gammadelta T Cells in Dystrophin-Deficient Mice. AB - Duchenne muscular dystrophy (DMD) is a fatal X-linked disorder caused by mutations in the dystrophin gene that lead to degeneration of skeletal and cardiac muscles and to chronic inflammation. Despite the importance of gammadelta T cells in many diseases, this cellular subpopulation has not been described in DMD patients or in mdx mice, a widely used mouse model for studying DMD. Therefore, in this study, we aimed to evaluate the migration of gammadelta T cells to the cardiac muscle of mdx mice and to characterize their phenotype and functional activity. We observed no migration of gammadelta T cells to skeletal muscles, but these cells were found in the hearts of mdx mice during the study period, reaching a peak in 12-wk-old mice. These cells migrate primarily owing to CCL2 and CCL5 chemokines produced by cardiac tissue, and they are Vgamma1+/CD27+ and thus produce high levels of IFN-gamma. In vivo depletion of the gammadelta T cells revealed gammadelta T cell-dependent cardiac inflammatory immunoregulation, with increased numbers of CD3+CD4+, CD3+CD8+, and, in particular, F4/80+ cells in the heart and increased cardiac damage in mdx mice. We also observed in vitro that purified cardiac Gammadelta T cells are cytotoxic against adherent endomysial cardiac cells, mostly macrophages, but not against peritoneal cells, in a perforin/granzyme-dependent manner. Our present data indicate that gammadelta T cells exert protective effects on the hearts of mdx mice, possibly by selectively killing pathogenic macrophages, and this function may be important for the late onset of cardiac damage in DMD. PMID- 27707998 TI - G-CSF-Induced Suppressor IL-10+ Neutrophils Promote Regulatory T Cells That Inhibit Graft-Versus-Host Disease in a Long-Lasting and Specific Way. AB - Acute graft-versus-host disease (aGVHD) is the main complication of allogeneic hematopoietic stem cell transplantation, and many efforts have been made to overcome this important limitation. We showed previously that G-CSF treatment generates low-density splenic granulocytes that inhibit experimental aGVHD. In this article, we show that aGVHD protection relies on incoming IL-10+ neutrophils from G-CSF-treated donor spleen (G-Neutrophils). These G-Neutrophils have high phagocytic capacity, high peroxide production, low myeloperoxidase activity, and low cytoplasmic granule content, which accounts for their low density. Furthermore, they have low expression of MHC class II, costimulatory molecules, and low arginase1 expression. Also, they have low IFN-gamma, IL-17F, IL-2, and IL 12 levels, with increased IL-10 production and NO synthase 2 expression. These features are in accordance with the modulatory capacity of G-Neutrophils on regulatory T cell (Treg) generation. In vivo, CD25+ Treg depletion shortly after transplantation with splenic cells from G-CSF-treated donors blocks suppression of aGVHD, suggesting Treg involvement in the protection induced by the G Neutrophils. The immunocompetence and specificity of the semiallogeneic T cells, long-term after the bone marrow transplant using G-Neutrophils, were confirmed by third-party skin graft rejection; importantly, a graft-versus-leukemia assay showed that T cell activity was maintained, and all of the leukemic cells were eliminated. We conclude that G-CSF treatment generates a population of activated and suppressive G-Neutrophils that reduces aGVHD in an IL-10- and Treg-dependent manner, while maintaining immunocompetence and the graft versus leukemia effect. PMID- 27707997 TI - Mannan-Binding Lectin-Associated Serine Protease 1/3 Cleavage of Pro-Factor D into Factor D In Vivo and Attenuation of Collagen Antibody-Induced Arthritis through Their Targeted Inhibition by RNA Interference-Mediated Gene Silencing. AB - The complement system is proposed to play an important role in the pathogenesis of rheumatoid arthritis (RA). The complement system mannan-binding lectin associated serine proteases (MASP)-1/3 cleave pro-factor D (proDf; inactive) into Df (active), but it is unknown where this cleavage occurs and whether inhibition of MASP-1/3 is a relevant therapeutic strategy for RA. In the present study, we show that the cleavage of proDf into Df by MASP-1/3 can occur in the circulation and that inhibition of MASP-1/3 by gene silencing is sufficient to ameliorate collagen Ab-induced arthritis in mice. Specifically, to examine the cleavage of proDf into Df, MASP-1/3-producing Df-/- liver tissue (donor) was transplanted under the kidney capsule of MASP-1/3-/- (recipient) mice. Five weeks after the liver transplantation, cleaved Df was present in the circulation of MASP-1/3-/- mice. To determine the individual effects of MASP-1/3 and Df gene silencing on collagen Ab-induced arthritis, mice were injected with scrambled, MASP-1/3 targeted, or Df-targeted small interfering RNAs (siRNAs). The mRNA levels for MASP-1 and -3 decreased in the liver to 62 and 58%, respectively, in mice injected with MASP-1/3 siRNAs, and Df mRNA decreased to 53% in the adipose tissue of mice injected with Df siRNAs; additionally, circulating MASP-1/3 and Df protein levels were decreased. In mice injected with both siRNAs the clinical disease activity, histopathologic injury scores, C3 deposition, and synovial macrophage/neutrophil infiltration were significantly decreased. Thus, MASP-1/3 represent a new therapeutic target for the treatment of RA, likely through both direct effects on the lectin pathway and indirectly through the alternative pathway.

PMID- 27708000 TI - Retrospective analysis of eliminating modified ultrafiltration after pediatric cardiopulmonary bypass. AB - Modified ultrafiltration (MUF) is a technique which is commonly used immediately post-cardiopulmonary bypass (CPB) for open heart surgery in children. There are many advantages of MUF, but there are also a number of less reported disadvantages. At our institution, after considering all of the available data, a decision was made to no longer perform MUF. The primary motivation being the simplified and miniaturized CPB circuit would reduce hemodilution, decrease our likelihood of reaching our transfusion trigger during CPB and, potentially, improve safety. This study reports the before and after data from this practice change. A total of 160 patients less than 8kg were studied over 38 months and divided into neonatal and pediatric cohorts. Parameters reported in this study include: demographics, hematocrit, blood product transfusion, hemostasis, hemodynamics and outcomes. Although retrospective, our analysis supports an advantage of preventing hemodilution (via circuit miniaturization) versus reversing hemodilution (via MUF) at our institution with the patient population we examined. PMID- 27707999 TI - A Model of Somatic Hypermutation Targeting in Mice Based on High-Throughput Ig Sequencing Data. AB - Analyses of somatic hypermutation (SHM) patterns in B cell Ig sequences have important basic science and clinical applications, but they are often confounded by the intrinsic biases of SHM targeting on specific DNA motifs (i.e., hot and cold spots). Modeling these biases has been hindered by the difficulty in identifying mutated Ig sequences in vivo in the absence of selection pressures, which skew the observed mutation patterns. To generate a large number of unselected mutations, we immunized B1-8 H chain transgenic mice with nitrophenyl to stimulate nitrophenyl-specific lambda+ germinal center B cells and sequenced the unexpressed kappa L chains using next-generation methods. Most of these kappa sequences had out-of-frame junctions and were presumably uninfluenced by selection. Despite being nonfunctionally rearranged, they were targeted by SHM and displayed a higher mutation frequency than functional sequences. We used 39,173 mutations to construct a quantitative SHM targeting model. The model showed targeting biases that were consistent with classic hot and cold spots, yet revealed additional highly mutable motifs. We observed comparable targeting for functional and nonfunctional sequences, suggesting similar biological processes operate at both loci. However, we observed species- and chain-specific targeting patterns, demonstrating the need for multiple SHM targeting models. Interestingly, the targeting of C/G bases and the frequency of transition mutations at C/G bases was higher in mice compared with humans, suggesting lower levels of DNA repair activity in mice. Our models of SHM targeting provide insights into the SHM process and support future analyses of mutation patterns. PMID- 27708002 TI - Retinal nerve fibre myelination.

AB - An estimated 5.1 million Americans have chronic heart failure and this is expected to increase 25% by 2030. Heart failure is a clinical syndrome that evolves from either functional or structural changes to the ventricles that lead to filling or ejection abnormalities. Thus far, pharmacotherapy has been show to be beneficial in patients only with reduced ejection fraction; however, new therapies have been developed in hopes of reducing the burden of heart failure. In this review, we will discuss current pharmacotherapies recommended in American College of Cardiology/American Heart Association guidelines, the evidence behind these recommendations as well as new and emerging therapies that have been developed.

AB - Medical registrars have been described as the 'workhorses' of National Health Service hospitals, being at the interface of acute and chronic health services. They are expected to demonstrate effective leadership skills. There are concerns from the Royal College of Physicians that medical registrars are being overwhelmed and unsupported by organisations, and are struggling in their ability to provide safe, high-quality patient care. Junior colleagues are also being deterred by general medical specialties by the prospect of becoming the 'Med Reg'. There is a growing need to support medical registrars in several key aspects of training, not least medical leadership. Thus far, there has been a distinct disparity in the provision of medical leadership training for junior doctors in the UK that has adversely affected the standard of care given to patients. Recent landmark reviews and initiatives, principally the Medical Leadership Competency Framework, have raised awareness of leadership competencies for all doctors and the need for their incorporation into undergraduate and postgraduate curricula. It is hoped that interactive strategies to engage medical registrars in leadership training will lead to positive results including improvements in interdisciplinary communication, patient outcomes and fulfilment of curriculum competencies. Organisations have a duty to improve the quality of medical leadership training so that doctors feel equipped to influence change throughout their careers and be tomorrow's leaders. This review outlines the deficiencies in training, the importance of developing leadership skills in medical registrars and educational strategies that could be implemented by organisations in a cost-effective manner.

AB - In 2001, Rivers and colleagues published a randomized controlled trial of early goal-directed therapy (EGDT) for the treatment of sepsis. More than a decade later, it remains a landmark achievement. The study proved the benefits of early aggressive treatment of sepsis. However, many questions remain about specific aspects of the complex EGDT algorithm. Recently, 3 large trials attempted to replicate these results. None of the studies demonstrated a benefit of an EGDT protocol for sepsis. This review explores the physiologic basis of goal-directed therapy, including the hemodynamic targets and the therapeutic interventions. An understanding of the physiologic basis of EGDT helps reconcile the results of the clinical trials.

However, much of our modern science and technology relies on materials with defects and disorders, and their three-dimensional (3D) atomic structures are not accessible to crystallography. One method capable of addressing this major challenge is atomic electron tomography. By combining advanced electron microscopes and detectors with powerful data analysis and tomographic reconstruction algorithms, it is now possible to determine the 3D atomic structure of crystal defects such as grain boundaries, stacking faults, dislocations, and point defects, as well as to precisely localize the 3D coordinates of individual atoms in materials without assuming crystallinity. Here we review the recent advances and the interdisciplinary science enabled by this methodology. We also outline further research needed for atomic electron tomography to address long-standing unresolved problems in the physical sciences. PMID- 27708012 TI - Speaking of insects.... PMID- 27708014 TI - The Subduction Zone Observatory takes shape. PMID- 27708011 TI - RNA G-quadruplexes are globally unfolded in eukaryotic cells and depleted in bacteria. AB - In vitro, some RNAs can form stable four-stranded structures known as G quadruplexes. Although RNA G-quadruplexes have been implicated in posttranscriptional gene regulation and diseases, direct evidence for their formation in cells has been lacking. Here, we identified thousands of mammalian RNA regions that can fold into G-quadruplexes in vitro, but in contrast to previous assumptions, these regions were overwhelmingly unfolded in cells. Model RNA G-quadruplexes that were unfolded in eukaryotic cells were folded when ectopically expressed in Escherichia coli; however, they impaired translation and growth, which helps explain why we detected few G-quadruplex-forming regions in bacterial transcriptomes. Our results suggest that eukaryotes have a robust machinery that globally unfolds RNA G-quadruplexes, whereas some bacteria have instead undergone evolutionary depletion of G-quadruplex-forming sequences. PMID- 27708008 TI - A global genetic interaction network maps a wiring diagram of cellular function. AB - We generated a global genetic interaction network for Saccharomyces cerevisiae, constructing more than 23 million double mutants, identifying about 550,000 negative and about 350,000 positive genetic interactions. This comprehensive network maps genetic interactions for essential gene pairs, highlighting essential genes as densely connected hubs. Genetic interaction profiles enabled assembly of a hierarchical model of cell function, including modules corresponding to protein complexes and pathways, biological processes, and cellular compartments. Negative interactions connected functionally related genes, mapped core bioprocesses, and identified pleiotropic genes, whereas positive interactions often mapped general regulatory connections among gene pairs, rather than shared functionality. The global network illustrates how coherent sets of genetic interactions connect protein complex and pathway modules to map a functional wiring diagram of the cell.

The behavior of such a layer at subduction zones remains unexplored. We present a tomographic model, derived from on- and offshore seismic experiments, that reveals a strong low-velocity feature beneath the subducting Juan de Fuca slab along the entire Cascadia subduction zone. Through simple geodynamic arguments, we propose that this low-velocity feature is the accumulation of material from a thin, weak, buoyant layer present beneath the entire oceanic lithosphere. The presence of this feature could have major implications for our understanding of the asthenosphere and subduction zone dynamics.

AB - Hybrid lead halide perovskites exhibit carrier properties that resemble those of pristine nonpolar semiconductors despite static and dynamic disorder, but how carriers are protected from efficient scattering with charged defects and optical phonons is unknown. Here, we reveal the carrier protection mechanism by comparing three single-crystal lead bromide perovskites: CH3NH3PbBr3, CH(NH2)2PbBr3, and CsPbBr3 We observed hot fluorescence emission from energetic carriers with ~102 picosecond lifetimes in CH3NH3PbBr3 or CH(NH2)2PbBr3, but not in CsPbBr3 The hot fluorescence is correlated with liquid-like molecular reorientational motions, suggesting that dynamic screening protects energetic carriers via solvation or large polaron formation on time scales competitive with that of ultrafast cooling. Similar protections likely exist for band-edge carriers. The long-lived energetic carriers may enable hot-carrier solar cells with efficiencies exceeding the Shockley-Queisser limit. PMID- 27708034 TI - High-quality graphene via microwave reduction of solution-exfoliated graphene oxide. AB - Efficient exfoliation of graphite in solutions to obtain high-quality graphene flakes is desirable for printable electronics, catalysis, energy storage, and composites. Graphite oxide with large lateral dimensions has an exfoliation yield of ~100%, but it has not been possible to completely remove the oxygen functional groups so that the reduced form of graphene oxide (GO; reduced form: rGO) remains a highly disordered material. Here we report a simple, rapid method to reduce GO into pristine graphene using 1- to 2-second pulses of microwaves. The desirable structural properties are translated into mobility values of >1000 square centimeters per volt per second in field-effect transistors with microwave reduced GO (MW-rGO) as the channel material and into particularly high activity for MW-rGO catalyst support toward oxygen evolution reactions. PMID- 27708031 TI - Plant diversity patterns in neotropical dry forests and their conservation implications. AB - Seasonally dry tropical forests are distributed across Latin America and the Caribbean and are highly threatened, with less than 10% of their original extent remaining in many countries. Using 835 inventories covering 4660 species of woody plants, we show marked floristic turnover among inventories and regions, which may be higher than in other neotropical biomes, such as savanna. Such high floristic turnover indicates that numerous conservation areas across many countries will be needed to protect the full diversity of tropical dry forests. Our results provide a scientific framework within which national decision-makers can contextualize the floristic significance of their dry forest at a regional and continental scale. PMID- 27708035 TI - Surface uplift and time-dependent seismic hazard due to fluid injection in eastern Texas. AB - Observations that unequivocally link seismicity and wastewater injection are scarce. Here we show that wastewater injection in eastern Texas causes uplift, detectable in radar interferometric data up to >8 kilometers from the wells. Using measurements of uplift, reported injection data, and a poroelastic model, we computed the crustal strain and pore pressure. We infer that an increase of >1 megapascal in pore pressure in rocks with low compressibility triggers earthquakes, including the 4.8-moment magnitude event that occurred on 17 May 2012, the largest earthquake recorded in eastern Texas. Seismic activity increased even while injection rates declined, owing to diffusion of pore pressure from earlier periods with higher injection rates. Induced seismicity potential is suppressed where tight confining formations prevent pore pressure from propagating into crystalline basement rocks. PMID- 27708036 TI - Radiocarbon constraints imply reduced carbon uptake by soils during the 21st century. AB - Soil is the largest terrestrial carbon reservoir and may influence the sign and magnitude of carbon cycle-climate feedbacks. Many Earth system models (ESMs) estimate a significant soil carbon sink by 2100, yet the underlying carbon dynamics determining this response have not been systematically tested against observations. We used 14C data from 157 globally distributed soil profiles sampled to 1-meter depth to show that ESMs underestimated the mean age of soil carbon by a factor of more than six (430 +/- 50 years versus 3100 +/- 1800 years). Consequently, ESMs overestimated the carbon sequestration potential of soils by a factor of nearly two (40 +/- 27%). These inconsistencies suggest that ESMs must better represent carbon stabilization processes and the turnover time of slow and passive reservoirs when simulating future atmospheric carbon dioxide dynamics. PMID- 27708037 TI - A Pleistocene ice core record of atmospheric O2 concentrations. AB - The history of atmospheric O2 partial pressures (Po2) is inextricably linked to the coevolution of life and Earth's biogeochemical cycles. Reconstructions of past Po2 rely on models and proxies but often markedly disagree. We present a record of Po2 reconstructed using O2/N2 ratios from ancient air trapped in ice. This record indicates that Po2 declined by 7 per mil (0.7%) over the past 800,000 years, requiring that O2 sinks were ~2% larger than sources. This decline is consistent with changes in burial and weathering fluxes of organic carbon and pyrite driven by either Neogene cooling or increasing Pleistocene erosion rates. The 800,000-year record of steady average carbon dioxide partial pressures (Pco2) but declining Po2 provides distinctive evidence that a silicate weathering feedback stabilizes Pco2 on million-year time scales. PMID- 27708038 TI - Convergent local adaptation to climate in distantly related conifers. AB - When confronted with an adaptive challenge, such as extreme temperature, closely related species frequently evolve similar phenotypes using the same genes. Although such repeated evolution is thought to be less likely in highly polygenic traits and distantly related species, this has not been tested at the genome scale. We performed a population genomic study of convergent local adaptation among two distantly related species, lodgepole pine and interior spruce. We identified a suite of 47 genes, enriched for duplicated genes, with variants associated with spatial variation in temperature or cold hardiness in both species, providing evidence of convergent local adaptation despite 140 million years of separate evolution. These results show that adaptation to climate can be genetically constrained, with certain key genes playing nonredundant roles. PMID- 27708040 TI - Managing my fear of missing out.

PMID- 27708039 TI - A secreted bacterial peptidoglycan hydrolase enhances tolerance to enteric pathogens. AB - The intestinal microbiome modulates host susceptibility to enteric pathogens, but the specific protective factors and mechanisms of individual bacterial species are not fully characterized. We show that secreted antigen A (SagA) from Enterococcus faecium is sufficient to protect Caenorhabditis elegans against Salmonella pathogenesis by promoting pathogen tolerance. The NlpC/p60 peptidoglycan hydrolase activity of SagA is required and generates muramyl peptide fragments that are sufficient to protect C. elegans against Salmonella pathogenesis in a tol-1-dependent manner. SagA can also be heterologously expressed and secreted to improve the protective activity of probiotics against Salmonella pathogenesis in C. elegans and mice. Our study highlights how protective intestinal bacteria can modify microbial-associated molecular patterns to enhance pathogen tolerance.

PMID- 27708046 TI - Primate Torpor Expression: Ghost of the Climatic Past. AB - Torpor, the controlled depression of virtually all bodily function during scarce periods, was verified in primates under free-ranging conditions less than two decades ago. The large variety of different torpor patterns found both within and among closely related species is particularly remarkable. To help unravel the cause of these variable patterns, our review investigates primate torpor use within an evolutionary framework. First, we provide an overview of heterothermic primate species, focusing on the Malagasy lemurs, and discuss their use of daily torpor or hibernation in relation to habitat type and climatic conditions. Second, we investigate environmental characteristics that may have been involved in shaping the high variability of torpor expression found in lemurs today. Third, we examine potential triggers for torpor use in lemurs. We propose the "torpor refugia hypothesis" to illustrate how disparate primate torpor patterns possibly evolved in response to environmental cues during glacial periods, when animals were restricted to different refuge habitats along riverine corridors. For example, individuals enduring harsher conditions at higher altitudes likely developed seasonal hibernation, whereas those inhabiting lower elevation river catchments might have coped with unfavorable conditions by employing daily torpor. The ultimate stimuli triggering torpor use today likely differ between the different habitats of Madagascar. The broad diversity of torpor patterns in lemurs among closely related species, both within the same and in distinctly different habitat types, provides an ideal base for research into the stimuli for torpor use in endotherms in general. Our hypothesis highlights the importance of considering the environmental conditions under which ecosystems and species evolved when trying to explain physiological adaptations seen today. PMID- 27708045 TI - Evolutionary Medicine: The Ongoing Evolution of Human Physiology and Metabolism. AB - The field of evolutionary medicine uses evolutionary principles to understand changes in human anatomy and physiology that have occurred over time in response to environmental changes. Through this evolutionary-based approach, we can understand disease as a consequence of anatomical and physiological "trade-offs" that develop to facilitate survival and reproduction. We demonstrate how diachronic study of human anatomy and physiology is fundamental for an increased understanding of human health and disease. PMID- 27708047 TI - Physiological Challenges to Fishes in a Warmer and Acidified Future. AB - With the projected levels of global warming and ocean acidification, fishes have to face warmer waters with CO2 levels that are the highest in over 30 million years. The resultant rise in body temperature means that metabolic rates of fish will increase, and some may become energetically compromised. No less worrying, and maybe more surprising, is that rising CO2 concentrations appear to trigger pH regulatory mechanisms that disrupts neural ion gradients, leading to altered neurotransmitter function and maladaptive behavioral changes. We point out the many outstanding questions, including the ultimate one: Will fish be able to adapt to these challenges? PMID- 27708048 TI - Cephalopod Susceptibility to Asphyxiation via Ocean Incalescence, Deoxygenation, and Acidification. AB - Squids are powerful swimmers with high metabolic rates despite constrained oxygen uptake and transport. They have evolved novel physiological strategies for survival in extreme environments that provide insight into their susceptibility to asphyxiation under anthropogenic ocean incalescence (warming), deoxygenation, and acidification. Plasticity of ecological and physiological traits, in conjunction with vertical and latitudinal mobility, may explain their evolutionary persistence and ensure their future survival. PMID- 27708049 TI - Cardiovascular Physiology of Dinosaurs. AB - Cardiovascular function in dinosaurs can be inferred from fossil evidence with knowledge of how metabolic rate, blood flow rate, blood pressure, and heart size are related to body size in living animals. Skeletal stature and nutrient foramen size in fossil femora provide direct evidence of a high arterial blood pressure, a large four-chambered heart, a high aerobic metabolic rate, and intense locomotion. But was the heart of a huge, long-necked sauropod dinosaur able to pump blood up 9 m to its head? PMID- 27708051 TI - Improving efficiency and stability of perovskite solar cells with photocurable fluoropolymers. AB - Organometal halide perovskite solar cells have demonstrated high conversion efficiency but poor long-term stability against ultraviolet irradiation and water. We show that rapid light-induced free-radical polymerization at ambient temperature produces multifunctional fluorinated photopolymer coatings that confer luminescent and easy-cleaning features on the front side of the devices, while concurrently forming a strongly hydrophobic barrier toward environmental moisture on the back contact side. The luminescent photopolymers re-emit ultraviolet light in the visible range, boosting perovskite solar cells efficiency to nearly 19% under standard illumination. Coated devices reproducibly retain their full functional performance during prolonged operation, even after a series of severe aging tests carried out for more than 6 months. PMID- 27708050 TI - Breathtaking Songs: Coordinating the Neural Circuits for Breathing and Singing. AB - The vocal behavior of birds is remarkable for its diversity, and songs can feature elaborate characteristics such as long duration, rapid temporal pattern, and broad frequency range. The respiratory system plays a central role in generating the complex song patterns that must be integrated with its life sustaining functions. Here, we explore how precise coordination between the neural circuits for breathing and singing is fundamental to production of these remarkable behaviors. PMID- 27708053 TI - Incorporation of rubidium cations into perovskite solar cells improves photovoltaic performance. AB - All of the cations currently used in perovskite solar cells abide by the tolerance factor for incorporation into the lattice. We show that the small and oxidation-stable rubidium cation (Rb+) can be embedded into a "cation cascade" to create perovskite materials with excellent material properties. We achieved stabilized efficiencies of up to 21.6% (average value, 20.2%) on small areas (and a stabilized 19.0% on a cell 0.5 square centimeters in area) as well as an electroluminescence of 3.8%. The open-circuit voltage of 1.24 volts at a band gap of 1.63 electron volts leads to a loss in potential of 0.39 volts, versus 0.4 volts for commercial silicon cells. Polymer-coated cells maintained 95% of their initial performance at 85 degrees C for 500 hours under full illumination and maximum power point tracking. PMID- 27708052 TI - A chemical biology route to site-specific authentic protein modifications. AB - Many essential biological processes are controlled by posttranslational protein modifications. The inability to synthetically attain the diversity enabled by these modifications limits functional studies of many proteins. We designed a three-step approach for installing authentic posttranslational modifications in recombinant proteins. We first use the established O-phosphoserine (Sep) orthogonal translation system to create a Sep-containing recombinant protein. The Sep residue is then dephosphorylated to dehydroalanine (Dha). Last, conjugate addition of alkyl iodides to Dha, promoted by zinc and copper, enables chemoselective carbon-carbon bond formation. To validate our approach, we produced histone H3, ubiquitin, and green fluorescent protein variants with site specific modifications, including different methylations of H3K79. The methylated histones stimulate transcription through histone acetylation. This approach offers a powerful tool to engineer diverse designer proteins. PMID- 27708054 TI - Aerobic glycolysis promotes T helper 1 cell differentiation through an epigenetic mechanism. AB - Aerobic glycolysis (the Warburg effect) is a metabolic hallmark of activated T cells and has been implicated in augmenting effector T cell responses, including expression of the proinflammatory cytokine interferon-gamma (IFN-gamma), via 3' untranslated region (3'UTR)-mediated mechanisms. Here, we show that lactate dehydrogenase A (LDHA) is induced in activated T cells to support aerobic glycolysis but promotes IFN-gamma expression independently of its 3'UTR. Instead, LDHA maintains high concentrations of acetyl-coenzyme A to enhance histone acetylation and transcription of Ifng Ablation of LDHA in T cells protects mice from immunopathology triggered by excessive IFN-gamma expression or deficiency of regulatory T cells. These findings reveal an epigenetic mechanism by which aerobic glycolysis promotes effector T cell differentiation and suggest that LDHA may be targeted therapeutically in autoinflammatory diseases. PMID- 27708055 TI - A selective insecticidal protein from Pseudomonas for controlling corn rootworms. AB - The coleopteran insect western corn rootworm (WCR) (Diabrotica virgifera virgifera LeConte) is a devastating crop pest in North America and Europe. Although crop plants that produce Bacillus thuringiensis (Bt) proteins can limit insect infestation, some insect populations have evolved resistance to Bt proteins. Here we describe an insecticidal protein, designated IPD072Aa, that is isolated from Pseudomonas chlororaphis. Transgenic corn plants expressing IPD072Aa show protection from WCR insect injury under field conditions. IPD072Aa leaves several lepidopteran and hemipteran insect species unaffected but is effective in killing WCR larvae that are resistant to Bt proteins produced by currently available transgenic corn. IPD072Aa can be used to protect corn crops against WCRs. PMID- 27708056 TI - Structural basis for the gating mechanism of the type 2 ryanodine receptor RyR2. AB - RyR2 is a high-conductance intracellular calcium (Ca2+) channel that controls the release of Ca2+ from the sarco(endo)plasmic reticulum of a variety of cells. Here, we report the structures of RyR2 from porcine heart in both the open and closed states at near-atomic resolutions determined using single-particle electron cryomicroscopy. Structural comparison reveals a breathing motion of the overall cytoplasmic region resulted from the interdomain movements of amino terminal domains (NTDs), Helical domains, and Handle domains, whereas almost no intradomain shifts are observed in these armadillo repeats-containing domains. Outward rotations of the Central domains, which integrate the conformational changes of the cytoplasmic region, lead to the dilation of the cytoplasmic gate through coupled motions. Our structural and mutational characterizations provide important insights into the gating and disease mechanism of RyRs. PMID- 27708057 TI - Systematic mapping of functional enhancer-promoter connections with CRISPR interference. AB - Gene expression in mammals is regulated by noncoding elements that can affect physiology and disease, yet the functions and target genes of most noncoding elements remain unknown. We present a high-throughput approach that uses clustered regularly interspaced short palindromic repeats (CRISPR) interference (CRISPRi) to discover regulatory elements and identify their target genes. We assess >1 megabase of sequence in the vicinity of two essential transcription factors, MYC and GATA1, and identify nine distal enhancers that control gene expression and cellular proliferation. Quantitative features of chromatin state and chromosome conformation distinguish the seven enhancers that regulate MYC from other elements that do not, suggesting a strategy for predicting enhancer promoter connectivity. This CRISPRi-based approach can be applied to dissect transcriptional networks and interpret the contributions of noncoding genetic variation to human disease. PMID- 27708059 TI - Posttranslational mutagenesis: A chemical strategy for exploring protein side chain diversity. AB - Posttranslational modification of proteins expands their structural and functional capabilities beyond those directly specified by the genetic code. However, the vast diversity of chemically plausible (including unnatural but functionally relevant) side chains is not readily accessible. We describe C (sp3) C (sp3) bond-forming reactions on proteins under biocompatible conditions, which exploit unusual carbon free-radical chemistry, and use them to form Cbeta-Cgamma bonds with altered side chains. We demonstrate how these transformations enable a wide diversity of natural, unnatural, posttranslationally modified (methylated, glycosylated, phosphorylated, hydroxylated), and labeled (fluorinated, isotopically labeled) side chains to be added to a common, readily accessible dehydroalanine precursor in a range of representative protein types and scaffolds. This approach, outside of the rigid constraints of the ribosome and enzymatic processing, may be modified more generally for access to diverse proteins. PMID- 27708058 TI - Rapid development of a DNA vaccine for Zika virus. AB - Zika virus (ZIKV) was identified as a cause of congenital disease during the explosive outbreak in the Americas and Caribbean that began in 2015. Because of the ongoing fetal risk from endemic disease and travel-related exposures, a vaccine to prevent viremia in women of childbearing age and their partners is imperative. We found that vaccination with DNA expressing the premembrane and envelope proteins of ZIKV was immunogenic in mice and nonhuman primates, and protection against viremia after ZIKV challenge correlated with serum neutralizing activity. These data not only indicate that DNA vaccination could be a successful approach to protect against ZIKV infection, but also suggest a protective threshold of vaccine-induced neutralizing activity that prevents viremia after acute infection. PMID- 27708061 TI - A Value Analysis of Lean Processes in Target Value Design and Integrated Project Delivery. AB - OBJECTIVE: To investigate what key stakeholders consider to be the advantages and the opportunities for improvement in using lean thinking and tools in the integrated project delivery (IPD) process. METHOD: A detailed literature review was followed by case study of a Lean-IPD project. Interviews with members of the project leadership team, focus groups with the integrated team as well as the design team, and an online survey of all stakeholders were conducted. ANALYSIS: Statistical analysis and thematic content analysis were used to analyze the data, followed by a plus-delta analysis. RESULTS: (1) Learning is a large, implicit benefit of Lean-IPD that is not currently captured by any success metric; (2) the cardboard mock-up was the most successful lean strategy; (3) although a collaborative project, the level of influence of different stakeholder groups was perceived to be different by different stakeholders; (4) overall, Lean-IPD was rated as better than traditional design-bid-build methods; and (5) opportunities for improvement reported were increase in accurate cost estimating, more efficient use of time, perception of imbalance of control/influence, and need for facilitation (which represents different points of view). CONCLUSION: While lean tools and an IPD method are preferred to traditional design-bid-build methods, the perception of different stakeholders varies and more work needs to be done to allow a truly shared decision-making model. Learning was identified as one of the biggest advantages. PMID- 27708060 TI - How economic, humanitarian, and religious concerns shape European attitudes toward asylum seekers. AB - What types of asylum seekers are Europeans willing to accept? We conducted a conjoint experiment asking 18,000 eligible voters in 15 European countries to evaluate 180,000 profiles of asylum seekers that randomly varied on nine attributes. Asylum seekers who have higher employability, have more consistent asylum testimonies and severe vulnerabilities, and are Christian rather than Muslim received the greatest public support. These results suggest that public preferences over asylum seekers are shaped by sociotropic evaluations of their potential economic contributions, humanitarian concerns about the deservingness of their claims, and anti-Muslim bias. These preferences are similar across respondents of different ages, education levels, incomes, and political ideologies, as well as across the surveyed countries. This public consensus on what types of asylum seekers to accept has important implications for theory and policy. PMID- 27708062 TI - Homoharringtonine (omacetaxine mepesuccinate) as an adjunct for FLT3-ITD acute myeloid leukemia. AB - An in vitro drug-screening platform on patient samples was developed and validated to design personalized treatment for relapsed/refractory acute myeloid leukemia (AML). Unbiased clustering and correlation showed that homoharringtonine (HHT), also known as omacetaxine mepesuccinate, exhibited preferential antileukemia effect against AML carrying internal tandem duplication of fms-like tyrosine kinase 3 (FLT3-ITD). It worked synergistically with FLT3 inhibitors to suppress leukemia growth in vitro and in xenograft mouse models. Mechanistically, the effect was mediated by protein synthesis inhibition and reduction of short lived proteins, including total and phosphorylated forms of FLT3 and its downstream signaling proteins. A phase 2 clinical trial of sorafenib and HHT combination treatment in FLT3-ITD AML patients resulted in complete remission (true or with insufficient hematological recovery) in 20 of 24 patients (83.3%), reduction of ITD allelic burden, and median leukemia-free and overall survivals of 12 and 33 weeks. The regimen has successfully bridged five patients to allogeneic hematopoietic stem cell transplantation and was well tolerated in patients unfit for conventional chemotherapy, including elderly and heavily pretreated patients. This study validated the principle and clinical relevance of in vitro drug testing and identified an improved treatment for FLT3-ITD AML. The results provided the foundation for phase 2/3 clinical trials to ascertain the clinical efficacy of FLT3 inhibitors and HHT in combination. PMID- 27708063 TI - Mechanistic modeling of hemoglobin glycation and red blood cell kinetics enables personalized diabetes monitoring. AB - The amount of glycated hemoglobin (HbA1c) in diabetic patients' blood provides the best estimate of the average blood glucose concentration over the preceding 2 to 3 months. It is therefore essential for disease management and is the best predictor of disease complications. Nevertheless, substantial unexplained glucose independent variation in HbA1c makes its reflection of average glucose inaccurate and limits the precision of medical care for diabetics. The true average glucose concentration of a nondiabetic and a poorly controlled diabetic may differ by less than 15 mg/dl, but patients with identical HbA1c values may have true average glucose concentrations that differ by more than 60 mg/dl. We combined a mechanistic mathematical model of hemoglobin glycation and red blood cell kinetics with large sets of within-patient glucose measurements to derive patient specific estimates of nonglycemic determinants of HbA1c, including mean red blood cell age. We found that between-patient variation in derived mean red blood cell age explains all glucose-independent variation in HbA1c. We then used our model to personalize prospective estimates of average glucose and reduced errors by more than 50% in four independent groups of greater than 200 patients. The current standard of care provided average glucose estimates with errors >15 mg/dl for one in three patients. Our patient-specific method reduced this error rate to 1 in 10. Our personalized approach should improve medical care for diabetes using existing clinical measurements. PMID- 27708064 TI - Birefringence microscopy platform for assessing airway smooth muscle structure and function in vivo. AB - The inability to visualize airway smooth muscle (ASM) cells in vivo is a major obstacle in understanding their role in normal physiology and diseases. At present, there is no imaging modality available to assess ASM in vivo. Confocal endomicroscopy lacks the penetration depth and field of view, and conventional optical coherence tomography (OCT) does not have sufficient contrast to differentiate ASM from surrounding tissues. We have developed a birefringence microscopy platform that leverages the micro-organization of tissue to add further dimension to traditional OCT. We have used this technology to validate ASM measurements in ex vivo swine and canine studies, visualize and characterize volumetric representations of ASM in vivo, and quantify and predict ASM contractile force as a function of optical retardation. We provide in vivo images and volumetric assessments of ASM in living humans and document structural disease variations in subjects with mild asthma. The opportunity to link inflammatory responses to ASM responses and to link ASM responses to clinical responses and outcomes could lead to an increased understanding of diseases of the airway and, ultimately, to improved patient outcomes. PMID- 27708067 TI - Feasibility and Reliability of the System for Observing Play and Leisure Activity in Youth (SOPLAY) for Measuring Moderate to Vigorous Physical Activity in Children Visiting an Interactive Children's Museum Exhibition. AB - PURPOSE: To test the feasibility and reliability of a direct observation method for measuring moderate to vigorous physical activity (MVPA) in children visiting an interactive children's museum exhibition. DESIGN: Direct observation was used to assess MVPA in children visiting an interactive children's museum exhibition on 2 weekend days in winter 2013. SETTING: The Children's Museum of Manhattan's EatSleepPlayTM: Building Health Every Day exhibition. PARTICIPANTS: Children (group level) visiting the museum exhibition. MEASURES: System for Observing Play and Leisure Activity in Youth (SOPLAY). ANALYSES: Interobserver reliability was analyzed for MVPA and activity type. Two-group analyses were conducted using a series of Wilcoxon rank sum tests. RESULTS: A total of 545 children were observed over 288 observations. No significant differences were found between observers for MVPA ( r = .91, P = .6804) or activity type (kappa = .90, P = .6334). Children participated in MVPA during 35.2% of all observations. No significant differences were found for participation in MVPA between boys (37.6%) and girls (32.8%, P = .1589). CONCLUSION: The SOPLAY may be a useful tool for measuring MVPA in interactive children's museum exhibitions. Research with multiple museum settings and diverse groups of children over longer periods of time is warranted to further establish the feasibility and reliability of the SOPLAY for measuring MVPA in this novel setting. PMID- 27708065 TI - Allergic asthma is distinguished by sensitivity of allergen-specific CD4+ T cells and airway structural cells to type 2 inflammation. AB - Despite systemic sensitization, not all allergic individuals develop asthma symptoms upon airborne allergen exposure. Determination of the factors that lead to the asthma phenotype in allergic individuals could guide treatment and identify novel therapeutic targets. We used segmental allergen challenge of allergic asthmatics (AA) and allergic nonasthmatic controls (AC) to determine whether there are differences in the airway immune response or airway structural cells that could drive the development of asthma. Both groups developed prominent allergic airway inflammation in response to allergen. However, asthmatic subjects had markedly higher levels of innate type 2 receptors on allergen-specific CD4+ T cells recruited into the airway. There were also increased levels of type 2 cytokines, increased total mucin, and increased mucin MUC5AC in response to allergen in the airways of AA subjects. Furthermore, type 2 cytokine levels correlated with the mucin response in AA but not AC subjects, suggesting differences in the airway epithelial response to inflammation. Finally, AA subjects had increased airway smooth muscle mass at baseline measured in vivo using novel orientation-resolved optical coherence tomography. Our data demonstrate that the development of allergic asthma is dependent on the responsiveness of allergen-specific CD4+ T cells to innate type 2 mediators as well as increased sensitivity of airway epithelial cells and smooth muscle to type 2 inflammation. PMID- 27708068 TI - Smoke-Free Men: Competing and Connecting to Quit. AB - PURPOSE: The purpose of this study was to explore gender-related factors that motivate and support men's smoking reduction and cessation to inform effective men-centered interventions. Approach or Design: Focus group design using a semi structured interview guide. SETTING: Three communities in British Columbia, Canada. PARTICIPANTS: A total of 56 men who currently smoked and were interested in reducing or quitting or had quit. INTERVENTION: N/A. METHODS: Data collected in 6 focus group discussions were transcribed and analyzed in accord with principles of thematic qualitative methods. RESULTS: We report the results across 4 interconnected themes: (1) the fight to quit takes several rounds, (2) the motivation of supportive competition, (3) challenges and benefits of connecting with smoke-free peers, and (4) playing up the physical and financial gains. CONCLUSIONS: Masculine-based perspectives positioned quitting alongside fighting for self-control, competing, connecting, physical prowess, and having extra cash as motivating components of programs to engage men in efforts to be smoke-free. It may be worthwhile to consider the inclusion of gain-framed and benefit-focused messaging in programs that support men's tobacco cessation. PMID- 27708066 TI - Long-term renal outcome in children with OCRL mutations: retrospective analysis of a large international cohort. AB - Background: Lowe syndrome (LS) and Dent-2 disease (DD2) are disorders associated with mutations in the OCRL gene and characterized by progressive chronic kidney disease (CKD). Here, we aimed to investigate the long-term renal outcome and identify potential determinants of CKD and its progression in children with these tubulopathies. Methods: Retrospective analyses were conducted of clinical and genetic data in a cohort of 106 boys (LS: 88 and DD2: 18). For genotype-phenotype analysis, we grouped mutations according to their type and localization. To investigate progression of CKD we used survival analysis by Kaplan-Meier method using stage 3 CKD as the end-point. Results: Median estimated glomerular filtration rate (eGFR) was lower in the LS group compared with DD2 (58.8 versus 87.4 mL/min/1.73 m2, P < 0.01). CKD stage II-V was found in 82% of patients, of these 58% and 28% had moderate-to-severe CKD in LS and DD2, respectively. Three patients (3%), all with LS, developed stage 5 of CKD. Survival analysis showed that LS was also associated with a faster CKD progression than DD2 (P < 0.01). On multivariate analysis, eGFR was dependent only on age (b = -0.46, P < 0.001). Localization, but not type of mutations, tended to correlate with eGFR. There was also no significant association between presence of nephrocalcinosis, hypercalciuria, proteinuria and number of adverse clinical events and CKD. Conclusions: CKD is commonly found in children with OCRL mutations. CKD progression was strongly related to the underlying diagnosis but did not associate with clinical parameters, such as nephrocalcinosis or proteinuria. PMID- 27708069 TI - Population-Level Measures to Predict Obesity Burden in Public Schools: Looking Upstream for Midstream Actions. AB - PURPOSE: To estimate school-level obesity burden, as reflected in prevalence of obesity, based on the characteristics of students' socioeconomic and geographic environments. DESIGN: Secondary analysis of cross-sectional data. SETTING: Public schools (N = 504) from 43 of 67 counties in Pennsylvania. PARTICIPANTS: Kindergarten through grade 12 students (N = 255 949). MEASURES: School-level obesity prevalence for the year 2014 was calculated from state-mandated student body mass index (BMI) measurements. Eighteen aggregate variables, characterizing schools and counties, were retrieved from federal data sources. ANALYSIS: Three classification variables-excess weight (BMI >= 85th percentile), obesity (BMI >= 95th percentile), and severe obesity (BMI > 35% or 120% of 95th percentile)-each with 3 groups of schools (low-, average-, and high-prevalence) were created for discriminant function analysis, based on state mean and standard deviation of school distribution. Analysis tested each classification model to reveal school- and county-level dimensions on which school groups differed from each other. RESULTS: Discriminant functions for obesity, which contained school enrollment, percentage of students receiving free/reduced-price lunch, percentage of black/Hispanic students, school location (suburban/other), percentage of county adults with postsecondary education, and percentage of county adults with obesity, yielded 67.86% correct classification (highest accuracy), compared to 34.23% schools classified by chance alone. CONCLUSION: In the absence of mandated student BMI screenings, the model developed in this study can be used to identify schools most likely to have high obesity burden and, thereafter, determine dissemination of enhanced resources for the implementation of proven prevention policies and programs.

PMID- 27708071 TI - An evaluation of the performance of SCORE Sweden 2015 in estimating cardiovascular risk: The Northern Sweden MONICA Study 1999-2014. AB - BACKGROUND: Risk prediction models for cardiovascular death are important for providing advice on lifestyle and in decision-making regarding primary preventive drug treatment. The latest Swedish version of the Systematic COronary Risk Evaluation (SCORE 2015) has yet not been tested in the population. OBJECTIVE: The objective of this study was to estimate the prevalence of high and very high risk of fatal cardiovascular disease (CVD) of the current population according to 2015 SCORE Sweden and to evaluate the predictive accuracy of the 2003 Swedish version of SCORE (2003 SCORE Sweden) and 2015 SCORE Sweden in a population with declining CVD mortality. METHODS: We estimated the high and very high risk group for cardiovascular death for individuals 40-65 years of age in the 2014 Northern Sweden MONICA population survey excluding subjects with known diabetes or previous CVD (n = 813). Using the 1999 MONICA survey (n = 3347) followed up for 10 years for CVD mortality, we assessed the calibration of both 2003 and 2015 SCORE Sweden. RESULTS: In 2014 2.6% of the population was considered at high or very high risk for fatal CVD, 95% were men and 76% were in the age group 60-65 years. Including subjects with a single markedly elevated risk factor, known diabetes or CVD, 12% of the population was at high or very high risk. During 10 years of follow-up of the 1999 cohort, 34 CVD deaths (24 men and 10 women) occurred. The 2003 SCORE overestimated the risk of death from CVD (ratio predicted/observed 2.3, P < 0.001) whereas the 2015 SCORE slightly overestimated the number of deaths (predicted/observed 1.3, P = 0.12). The 2015 SCORE predicted more accurately than the 2003 SCORE the number of deaths in the different risk and age categories. CONCLUSION: The 2015 SCORE Sweden more adequately than 2003 SCORE Sweden predicts the number of deaths. In 2014, the proportion of high-risk individuals is small in northern Sweden. The main use of 2015 SCORE Sweden would therefore be as an educational tool between the physician and people without diabetes or CVD in a consultation regarding cardiovascular risk. PMID- 27708072 TI - Do Villages Promote Aging in Place? Results of a Longitudinal Study. AB - Villages are a new, grassroots, consumer-directed model that aims to promote aging in place and prevent unwanted relocations for older adults. In exchange for a yearly membership fee, Villages provide seniors with opportunities for social engagement (social events and classes), civic engagement (member-to-member volunteer opportunities), and an array of support services. In total, 222 Village members were surveyed at intake and 12-month follow-up to examine changes in their confidence aging in place, social connectedness, and health. The strongest positive results were in the domain of confidence, including significantly greater confidence aging in place, perceived social support, and less intention to relocate after 1 year in the Village. As most seniors were in good health and well connected at the time they joined the Village, there were not improvements in health or social connectedness. Authors discuss the importance of longer term, longitudinal studies to examine the effectiveness of Villages in preventing institutionalization over time. PMID- 27708073 TI - Exploring Path Models of Disablement in Residential Care and Assisted Living Residents. AB - This study examined the relationships between individual and environmental factors and physical activity, and between physical activity and functional limitations and disability in residential care/assisted living (RC/AL) residents. Participants completed questionnaires and physical performance tests, and wore the Fitbit Motion Tracker(r) to capture physical activity. Model fit was analyzed using two-level path models with residents nested within RC/AL settings. Model parameters were estimated using the MPlus robust maximum likelihood method. A multilevel model with good fit (root mean square error of approximation = 0.07, comparative fit index [CFI] = 0.91) showed that persons with greater exercise self-efficacy were more physically active, and persons who were more physically active had better physical function and less disability. Setting-level factors did not significantly correlate with physical activity or disability. Although environmental factors may influence physical activity behavior, only individual factors were associated with physical activity in this sample of RC/AL residents. PMID- 27708075 TI - Multiprocess 3D printing for increasing component functionality. AB - Layer-by-layer deposition of materials to manufacture parts-better known as three dimensional (3D) printing or additive manufacturing-has been flourishing as a fabrication process in the past several years and now can create complex geometries for use as models, assembly fixtures, and production molds. Increasing interest has focused on the use of this technology for direct manufacturing of production parts; however, it remains generally limited to single-material fabrication, which can limit the end-use functionality of the fabricated structures. The next generation of 3D printing will entail not only the integration of dissimilar materials but the embedding of active components in order to deliver functionality that was not possible previously. Examples could include arbitrarily shaped electronics with integrated microfluidic thermal management and intelligent prostheses custom-fit to the anatomy of a specific patient. We review the state of the art in multiprocess (or hybrid) 3D printing, in which complementary processes, both novel and traditional, are combined to advance the future of manufacturing. PMID- 27708074 TI - The linker histone H1.0 generates epigenetic and functional intratumor heterogeneity. AB - Tumors comprise functionally diverse subpopulations of cells with distinct proliferative potential. Here, we show that dynamic epigenetic states defined by the linker histone H1.0 determine which cells within a tumor can sustain the long term cancer growth. Numerous cancer types exhibit high inter- and intratumor heterogeneity of H1.0, with H1.0 levels correlating with tumor differentiation status, patient survival, and, at the single-cell level, cancer stem cell markers. Silencing of H1.0 promotes maintenance of self-renewing cells by inducing derepression of megabase-sized gene domains harboring downstream effectors of oncogenic pathways. Self-renewing epigenetic states are not stable, and reexpression of H1.0 in subsets of tumor cells establishes transcriptional programs that restrict cancer cells' long-term proliferative potential and drive their differentiation. Our results uncover epigenetic determinants of tumor maintaining cells. PMID- 27708077 TI - News at a glance. PMID- 27708079 TI - Will Nobel Prize overlook LIGO's master builder?

PMID- 27708076 TI - Pathological alpha-synuclein transmission initiated by binding lymphocyte activation gene 3. AB - Emerging evidence indicates that the pathogenesis of Parkinson's disease (PD) may be due to cell-to-cell transmission of misfolded preformed fibrils (PFF) of alpha synuclein (alpha-syn). The mechanism by which alpha-syn PFF spreads from neuron to neuron is not known. Here, we show that LAG3 (lymphocyte-activation gene 3) binds alpha-syn PFF with high affinity (dissociation constant = 77 nanomolar), whereas the alpha-syn monomer exhibited minimal binding. alpha-Syn-biotin PFF binding to LAG3 initiated alpha-syn PFF endocytosis, transmission, and toxicity. Lack of LAG3 substantially delayed alpha-syn PFF-induced loss of dopamine neurons, as well as biochemical and behavioral deficits in vivo. The identification of LAG3 as a receptor that binds alpha-syn PFF provides a target for developing therapeutics designed to slow the progression of PD and related alpha-synucleinopathies.

AB - An accurate viscosity structure is critical to truthfully modeling lithosphere dynamics. Here, we report an attempt to infer the effective lithospheric viscosity from a high-resolution magnetotelluric (MT) survey across the western United States. The high sensitivity of MT fields to the presence of electrically conductive fluids makes it a promising proxy for determining mechanical strength variations throughout the lithosphere. We demonstrate how a viscosity structure, approximated from electrical resistivity, results in a geodynamic model that successfully predicts short-wavelength surface topography, lithospheric deformation, and mantle upwelling beneath recent volcanism. We further show that this viscosity is physically consistent with and better constrained than that derived from laboratory-based rheology. We conclude that MT imaging provides a practical observational constraint for quantifying the dynamic evolution of the continental lithosphere. PMID- 27708098 TI - Spiral density waves in a young protoplanetary disk. AB - Gravitational forces are expected to excite spiral density waves in protoplanetary disks, disks of gas and dust orbiting young stars. However, previous observations that showed spiral structure were not able to probe disk midplanes, where most of the mass is concentrated and where planet formation takes place. Using the Atacama Large Millimeter/submillimeter Array, we detected a pair of trailing symmetric spiral arms in the protoplanetary disk surrounding the young star Elias 2-27. The arms extend to the disk outer regions and can be traced down to the midplane. These millimeter-wave observations also reveal an emission gap closer to the star than the spiral arms. We argue that the observed spirals trace shocks of spiral density waves in the midplane of this young disk. PMID- 27708099 TI - Electron optics with p-n junctions in ballistic graphene. AB - Electrons transmitted across a ballistic semiconductor junction are expected to undergo refraction, analogous to light rays across an optical boundary. In graphene, the linear dispersion and zero-gap band structure admit highly transparent p-n junctions by simple electrostatic gating. Here, we employ transverse magnetic focusing to probe the propagation of carriers across an electrostatically defined graphene junction. We find agreement with the predicted Snell's law for electrons, including the observation of both positive and negative refraction. Resonant transmission across the p-n junction provides a direct measurement of the angle-dependent transmission coefficient. Comparing experimental data with simulations reveals the crucial role played by the effective junction width, providing guidance for future device design. Our results pave the way for realizing electron optics based on graphene p-n junctions. PMID- 27708100 TI - Ballistic miniband conduction in a graphene superlattice. AB - Rational design of long-period artificial lattices yields effects unavailable in simple solids. The moire pattern in highly aligned graphene/hexagonal boron nitride (h-BN) heterostructures is a lateral superlattice with high electron mobility and an unusual electronic dispersion whose miniband edges and saddle points can be reached by electrostatic gating. We investigated the dynamics of electrons in moire minibands by measuring ballistic transport between adjacent local contacts in a magnetic field, known as the transverse electron focusing effect. At low temperatures, we observed caustics of skipping orbits extending over hundreds of superlattice periods, reversals of the cyclotron revolution for successive minibands, and breakdown of cyclotron motion near van Hove singularities. At high temperatures, electron-electron collisions suppress focusing. Probing such miniband conduction properties is a necessity for engineering novel transport behaviors in superlattice devices. PMID- 27708101 TI - Unexpected rewards induce dopamine-dependent positive emotion-like state changes in bumblebees. AB - Whether invertebrates exhibit positive emotion-like states and what mechanisms underlie such states remain poorly understood. We demonstrate that bumblebees exhibit dopamine-dependent positive emotion-like states across behavioral contexts. After training with one rewarding and one unrewarding cue, bees that received pretest sucrose responded in a positive manner toward ambiguous cues. In a second experiment, pretest consumption of sucrose solution resulted in a shorter time to reinitiate foraging after a simulated predator attack. These behavioral changes were abolished with topical application of the dopamine antagonist fluphenazine. Further experiments established that pretest sucrose does not simply cause bees to become more exploratory. Our findings present a new opportunity for understanding the fundamental neural elements of emotions and may alter the view of how emotion states affect decision-making in animals. PMID- 27708102 TI - An Anthropocene map of genetic diversity. AB - The Anthropocene is witnessing a loss of biodiversity, with well-documented declines in the diversity of ecosystems and species. For intraspecific genetic diversity, however, we lack even basic knowledge on its global distribution. We georeferenced 92,801 mitochondrial sequences for >4500 species of terrestrial mammals and amphibians, and found that genetic diversity is 27% higher in the tropics than in nontropical regions. Overall, habitats that are more affected by humans hold less genetic diversity than wilder regions, although results for mammals are sensitive to choice of genetic locus. Our study associates geographic coordinates with publicly available genetic sequences at a massive scale, yielding an opportunity to investigate both the drivers of this component of biodiversity and the genetic consequences of the anthropogenic modification of nature. PMID- 27708103 TI - Ventral CA1 neurons store social memory. AB - The medial temporal lobe, including the hippocampus, has been implicated in social memory. However, it remains unknown which parts of these brain regions and their circuits hold social memory. Here, we show that ventral hippocampal CA1 (vCA1) neurons of a mouse and their projections to nucleus accumbens (NAc) shell play a necessary and sufficient role in social memory. Both the proportion of activated vCA1 cells and the strength and stability of the responding cells are greater in response to a familiar mouse than to a previously unencountered mouse. Optogenetic reactivation of vCA1 neurons that respond to the familiar mouse enabled memory retrieval and the association of these neurons with unconditioned stimuli. Thus, vCA1 neurons and their NAc shell projections are a component of the storage site of social memory. PMID- 27708107 TI - Doing science while black. PMID- 27708106 TI - Drosophila insulin release is triggered by adipose Stunted ligand to brain Methuselah receptor. AB - Animals adapt their growth rate and body size to available nutrients by a general modulation of insulin-insulin-like growth factor signaling. In Drosophila, dietary amino acids promote the release in the hemolymph of brain insulin-like peptides (Dilps), which in turn activate systemic organ growth. Dilp secretion by insulin-producing cells involves a relay through unknown cytokines produced by fat cells. Here, we identify Methuselah (Mth) as a secretin-incretin receptor subfamily member required in the insulin-producing cells for proper nutrient coupling. We further show, using genetic and ex vivo organ culture experiments, that the Mth ligand Stunted (Sun) is a circulating insulinotropic peptide produced by fat cells. Therefore, Sun and Mth define a new cross-organ circuitry that modulates physiological insulin levels in response to nutrients. PMID- 27708108 TI - Actigraphic Sleep Pattern of Preschoolers With ADHD. AB - OBJECTIVE: To assess the features of sleep in preschoolers with ADHD by means of questionnaire and actigraphy. METHOD: Twenty-five ADHD and 21 age-matched typically developing (TD) preschool children underwent the Child Behavior Checklist (CBCL) for ages 11/2 to 5 and Pre-School-Age Psychiatric Assessment interview. Sleep was assessed by means of a modified Sleep Disturbance Scale for Children and wrist actigraphy for at least 5 days. RESULTS: Children with ADHD, compared with TD, showed higher scores in CBCL Withdrawal (58.83 vs. 51.15, p < .0001), Attention Problems (69.88 vs. 51.54, p < .0001), and Aggressive Behavior (59.46 vs. 51.08, p < .0001) dimensions; they also showed increased actigraphic nocturnal activity (activity index 31.57 vs. 25.74, p < .05); and night-to-night variability for sleep minutes (56.44 vs. 32.79, p < .01), mean wake episodes (1.34 vs. 0.98, p < .05), mean activity (2.64 vs. 1.71, p < .05), and activity index (5.15 vs. 3.77, p < .05). CONCLUSION: This pilot study in preschoolers with ADHD showed increased motor activity during sleep and night-to-night variability for sleep duration and motor activity. PMID- 27708104 TI - High-resolution interrogation of functional elements in the noncoding genome. AB - The noncoding genome affects gene regulation and disease, yet we lack tools for rapid identification and manipulation of noncoding elements. We developed a CRISPR screen using ~18,000 single guide RNAs targeting >700 kilobases surrounding the genes NF1, NF2, and CUL3, which are involved in BRAF inhibitor resistance in melanoma. We find that noncoding locations that modulate drug resistance also harbor predictive hallmarks of noncoding function. With a subset of regions at the CUL3 locus, we demonstrate that engineered mutations alter transcription factor occupancy and long-range and local epigenetic environments, implicating these sites in gene regulation and chemotherapeutic resistance. Through our expansion of the potential of pooled CRISPR screens, we provide tools for genomic discovery and for elucidating biologically relevant mechanisms of gene regulation. PMID- 27708109 TI - Long-term clinical outcomes in patients with ST-segment elevation acute myocardial infarction complicated by cardiogenic shock due to acute pump failure. AB - BACKGROUND:: Cardiogenic shock remained the leading cause of death in ST-segment elevation acute myocardial infarction (STEMI) patients even in the primary percutaneous coronary intervention era. METHODS:: Among 3942 STEMI patients with primary percutaneous coronary intervention within 24 h after symptom-onset in the Coronary Revascularization Demonstrating Outcome Study in Kyoto acute myocardial infarction registry, the study population of the current analysis consisted of 466 STEMI patients who were complicated by cardiogenic shock due to acute pump failure. RESULTS:: The cumulative incidence of all-cause death of cardiogenic shock due to acute pump failure was 25.4% at 30 days, 38.7% at one year, and 51.4% at five years. Cumulative five-year incidence of all-cause death in patients with left main coronary artery culprit lesion was extremely high (left main coronary artery: 70.4%, left anterior descending artery: 52.5%, left circumflex artery: 50.6%, and right coronary artery; 44.3%, respectively, log rank p<0.001). The cumulative five-year incidence of all-cause death in patients with onset-to-balloon time ?3 h as well as those with door-to-balloon time ?90 min were significantly lower than those without (43.3% versus 55.5%, log-rank p=0.008, and 44.9% versus 55.8%, log-rank p=0.003, respectively). After adjusting for confounders, onset-to-balloon time ?3 h and door-to-balloon time ?90 min were independently associated with lower long-term risk for all-cause death (hazard ratio: 0.69, 95% confidence interval: 0.49-0.96, p=0.03, and hazard ratio: 0.73, 95% confidence interval: 0.53-0.98, p=0.04, respectively). CONCLUSIONS:: The long term mortality of STEMI patients complicated by cardiogenic shock due to acute pump failure remains high even in the current clinical practice. In this high risk category of patients, shorter onset-to-balloon and door-to-balloon time were associated with significantly lower long-term risk for mortality. PMID- 27708105 TI - Cyclin A2 is an RNA binding protein that controls Mre11 mRNA translation. AB - Cyclin A2 activates the cyclin-dependent kinases Cdk1 and Cdk2 and is expressed at elevated levels from S phase until early mitosis. We found that mutant mice that cannot elevate cyclin A2 are chromosomally unstable and tumor-prone. Underlying the chromosomal instability is a failure to up-regulate the meiotic recombination 11 (Mre11) nuclease in S phase, which leads to impaired resolution of stalled replication forks, insufficient repair of double-stranded DNA breaks, and improper segregation of sister chromosomes. Unexpectedly, cyclin A2 controlled Mre11 abundance through a C-terminal RNA binding domain that selectively and directly binds Mre11 transcripts to mediate polysome loading and translation. These data reveal cyclin A2 as a mechanistically diverse regulator of DNA replication combining multifaceted kinase-dependent functions with a kinase-independent, RNA binding-dependent role that ensures adequate repair of common replication errors. PMID- 27708110 TI - CHA2DS2-VASc risk factors as predictors of stroke after acute coronary syndrome: A systematic review and meta-analysis. AB - BACKGROUND: Stroke is a rare but serious complication of acute coronary syndrome. At present, no specific score exists to identify patients at higher risk. The aim of the present study is to test whether each clinical variable included in the CHA2DS2-VASc score retains its predictive value in patients with recent acute coronary syndrome, irrespective of atrial fibrillation. METHODS: The meta analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. All clinical trials and observational studies presenting data on the association between stroke/transient ischemic attack incidence and at least one CHA2DS2-VASc item in patients with a recent acute coronary syndrome were considered in the analysis. Atrial fibrillation diagnosis was also considered. RESULTS: The whole cohort included 558,193 patients of which 7108 (1.3%) had an acute stroke and/or transient ischemic attack during follow-up (median nine months; 1st-3rd quartile 1-12 months). Age and previous stroke had the highest odds ratios (odds ratio 2.60; 95% confidence interval 2.21-3.06 and odds ratio 2.74; 95% confidence interval 2.19-3.42 respectively), in accordance with the two-point value given in the CHA2DS2-VASc score. All other factors were positively associated with stroke, although with lower odds ratios. Atrial fibrillation, while present in only 11.2% of the population, confirmed its association with an increased risk of stroke and/or transient ischemic attack (odds ratio 2.04; 95% confidence interval 1.71-2.44). CONCLUSIONS: All risk factors included in the CHA2DS2-VASc score are associated with stroke/ transient ischemic attack in patients with recent acute coronary syndrome, and retain similar odds ratios to what already seen in atrial fibrillation. The utility of CHA2DS2-VASc score for risk stratification of stroke in patients with acute coronary syndrome remains to be determined. PMID- 27708111 TI - Zofenopril and ramipril in patients with left ventricular systolic dysfunction after acute myocardial infarction: A propensity analysis of the Survival of Myocardial Infarction Long-term Evaluation (SMILE) 4 study. AB - INTRODUCTION: This was a propensity score analysis of the prospective, randomized, double-blind Survival of Myocardial Infarction Long-term Evaluation (SMILE) 4 study in which one-year treatment with zofenopril 60 mg plus acetylsalicylic acid (ASA) 100 mg gave superior results compared to ramipril 10 mg plus ASA in terms of death or hospitalization for cardiovascular causes in patients with acute myocardial infarction (AMI) complicated by left ventricular dysfunction (LVD). MATERIALS AND METHODS: A total of 716 patients of the intention-to-treat population were divided into homogeneous propensity quintiles (Q) using a logistic regression model (QI: best risk profile; QV: worst risk profile). RESULTS: Treatment was associated with a similar low rate of major cardiovascular events in any Q. However, the efficacy of zofenopril was better than that of ramipril in QII, QV, and particularly QIII (odds ratio (OR) and 95% confidence interval: 0.43 (0.21-0.87), p<0.05]. This result was primarily attributed to a decrease in the risk of cardiovascular hospitalization, particularly striking in the QIII (OR: 0.40, 0.19-0.85; p<0.05). Mortality rate did not significantly differ between the two treatments in any Q. CONCLUSIONS: In the SMILE-4 study the propensity analysis confirmed the efficacy of zofenopril in the prevention of long-term cardiovascular outcomes irrespective of the cardiovascular risk profile of post-AMI patients. PMID- 27708112 TI - Unexpected Geographic Variability of the Free Running Period in the Linden Bug Pyrrhocoris apterus. AB - Circadian clocks keep organisms in synchrony with external day-night cycles. The free running period (FRP) of the clock, however, is usually only close to-not exactly-24 h. Here, we explored the geographical variation in the FRP of the linden bug, Pyrrhocoris apterus, in 59 field-lines originating from a wide variety of localities representing geographically different environments. We have identified a remarkable range in the FRPs between field-lines, with the fastest clock at ~21 h and the slowest close to 28 h, a range comparable to the collections of clock mutants in model organisms. Similarly, field-lines differed in the percentage of rhythmic individuals, with a minimum of 13.8% and a maximum of 86.8%. Although the FRP correlates with the latitude and perhaps with the altitude of the locality, the actual function of this FRP diversity is currently unclear. With the recent technological progress of massive parallel sequencing and genome editing, we can expect remarkable progress in elucidating the genetic basis of similar geographic variants in P. apterus or in similar emerging model species of chronobiology. PMID- 27708113 TI - Effectiveness of a brief community outreach tobacco cessation intervention in India: a cluster-randomised controlled trial (the BABEX Trial). AB - BACKGROUND: Tobacco use kills half a million people every month, most in low middle income countries (LMICs). There is an urgent need to identify potentially low-cost, scalable tobacco cessation interventions for these countries. OBJECTIVE: To evaluate a brief community outreach intervention delivered by health workers to promote tobacco cessation in India. DESIGN: Cluster-randomised controlled trial. SETTING: 32 low-income administrative blocks in Delhi, half government authorised ('resettlement colony') and half unauthorised ('J.J. cluster') communities. PARTICIPANTS: 1213 adult tobacco users. INTERVENTIONS: Administrative blocks were computer randomised in a 1:1 ratio, to the intervention (16 clusters; n=611) or control treatment (16 clusters; n=602), delivered and assessed at individual level between 07/2012 and 11/2013. The intervention was single session quit advice (15 min) plus a single training session in yogic breathing exercises; the control condition comprised very brief quit advice (1 min) alone. Both were delivered via outreach, with contact made though household visits. MEASUREMENTS: The primary outcome was 6-month sustained abstinence from all tobacco, assessed 7 months post intervention delivery, biochemically verified with salivary cotinine. RESULTS: The smoking cessation rate was higher in the intervention group (2.6% (16/611)) than in the control group (0.5% (3/602)) (relative risk=5.32, 95% CI 1.43 to 19.74, p=0.013). There was no interaction with type of tobacco use (smoked vs smokeless). Results did not change materially in adjusted analyses, controlling for participant characteristics. CONCLUSIONS: A single session community outreach intervention can increase tobacco cessation in LMIC. The effect size, while small, could impact public health if scaled up with high coverage. TRIAL REGISTRATION NUMBER: ISRCTCN23362894. PMID- 27708116 TI - ADHD medication prescription: Effects of child, sibling, parent and general practice characteristics. AB - Many children receive attention-deficit hyperactivity disorder (ADHD) medication, but factors that determine medication prescription are largely unknown. This study aimed to determine the relative impact of factors on the child, family and general practitioner (GP) practice level on ADHD medication prescription. We included 1259 Dutch children aged 6-18 years with a diagnostic code of ADHD or related behavioural problems (ICPC codes P20-P22) in NIVEL primary care database. Using multilevel analyses, we examined predictors of ADHD medication prescription. Children diagnosed as 'hyperactive' were 16 times more likely to be prescribed ADHD medication than those with 'behavioural concerns'. Children with a parent or sibling receiving ADHD medication were three to four times more likely to be prescribed ADHD medication themselves. Children from GP practices with a high percentage of children with ADHD were twice as likely to be prescribed ADHD medication. Concluding, factors on the individual, family and GP practice level determine ADHD medication prescription. Future research into the decision-making process for ADHD medication is warranted. PMID- 27708114 TI - Effect of statins on disease-related outcomes in patients with idiopathic pulmonary fibrosis. AB - BACKGROUND: Data are conflicting regarding the possible effects of statins in patients with idiopathic pulmonary fibrosis (IPF). This post hoc analysis assessed the effects of statin therapy on disease-related outcomes in IPF. METHODS: Patients randomised to placebo (n=624) in three controlled trials of pirfenidone in IPF (CAPACITY 004 and 006, ASCEND) were categorised by baseline statin use. Outcomes assessed during the 1-year follow-up included disease progression, mortality, hospitalisation and composite outcomes of death or >=10% absolute decline in FVC and death or >=50 m decline in 6-minute walk distance (6MWD). RESULTS: At baseline, 276 (44%) patients were statin users versus 348 (56%) non-users. Baseline characteristics were similar between groups, except statin users were older and had higher prevalence of cardiovascular disease and risk factors. In multivariate analyses adjusting for differences in baseline characteristics, statin users had lower risks of death or 6MWD decline (HR 0.69; 95% CI 0.48 to 0.99, p=0.0465), all-cause hospitalisation (HR 0.58; 95% CI 0.35 to 0.94, p=0.0289), respiratory-related hospitalisation (HR 0.44; 95% CI 0.25 to 0.80, p=0.0063) and IPF-related mortality (HR 0.36; 95% CI 0.14 to 0.95, p=0.0393) versus non-users. Non-significant treatment effects favouring statin use were observed for disease progression (HR 0.75; 95% CI 0.52 to 1.07, p=0.1135), all-cause mortality (HR 0.54; 95% CI 0.24 to 1.21, p=0.1369) and death or FVC decline (HR 0.71; 95% CI 0.48 to 1.07, p=0.1032). CONCLUSIONS: This post hoc analysis supports the hypothesis that statins may have a beneficial effect on clinical outcomes in IPF. Prospective clinical trials are required to validate these observations. TRIAL REGISTRATION NUMBERS: NCT01366209, NCT00287729 and NCT00287716.

AB - OBJECTIVE: To analyze gender differences in incidence and determinants of the components of the frailty phenotype. METHOD: A total of 1,413 older adults were selected in 2006. To estimate the incidence of each frailty component, only individuals who did not exhibit a given component at baseline (independently of the presence of other components) were included in the study. The variables of interest were socioeconomic, behavioral, clinical, anthropometric factors and physical performance. The incidence of each component in 2010 was the outcome. RESULTS: Unintentional weight loss and slowness were more incident in men up to 74 years of age. The other frailty components were more incident in women at all age groups, except weakness. Besides age, the determinants of incidence of the components of frailty were different between genders. DISCUSSION: Strategies for preventing or delaying the installation of frailty need to address gender differences, considering the greater complexity in the network determinants among women. PMID- 27708117 TI - Deflection Analysis of Different Needle Designs for Prostate Biopsy and Focal Therapy. AB - OBJECTIVE: The biopsy needles currently used were designed for a transrectal biopsy and are known to experience significant deflection from the point of entry into the gland to the needle tip. METHODS: Five designs were selected for testing: 18-gauge Bard, 15-gauge lancet tip needle with 12 degrees vet-point cannula, and trocar tip needle with 12 degrees , 15 degrees , and 20 degrees vet point cannulas. The 15-gauge needle was designed to take a variable specimen sample between 20 and 60 mm, whereas the Bard needle specimen bed was fixed at 20 mm. The needles were bench tested on a spring-loaded platform and fired into gelatin matrix with modulus of elasticity similar to human prostate. RESULTS: The Bard device with lancet tip needle deflected an average of 0.9 mm (range 0.3-1.3 mm) and 1.9 degrees (range 0.6 degrees -2.8 degrees ). Increasing needle diameter from 18-gauge Bard to 15-gauge variable with the same lancet tip needle design resulted in an average deflection across the 3 test lengths of 0.9 mm (range 0-2.0 mm) and 0.9 degrees (range 0 degrees -2.0 degrees ) with no significant difference. On the contrary, the use of the 3-point trocar tip needles with 12 degrees , 15 degrees , and 20 degrees vet-point cannulas demonstrated significant reduction in the extent of deflection in both millimeters and degrees. There was no deflection at the 2- and 4-cm shots for both spring loads and preloads for the 3 vet tip angles tested. At 6 cm, the 20 degrees vet tip performed the best. CONCLUSION: We proposed a mechanism that provides more accurate prostate sampling by combining a 3-point trocar tip on the needle with a 20 degrees vet tip on the cutting cannula. Using the phantom, mimicking prostate gland tissue density, no deflection was revealed between 20- and 60-mm biopsy lengths, which should permit a straight sample in the majority of prostate glands and improve cancer localization for focal therapy planning.

AB - As part of the HPTN 065 study in the Bronx, New York and Washington, the authors, we surveyed clinicians to assess for shifts in their practices and attitudes around HIV treatment and prevention. Antiretroviral therapy (ART)-prescribing clinicians at 39 HIV care sites were offered an anonymous Web-based survey at baseline (2010-2011) and at follow-up (2013). The 165 respondents at baseline and 141 respondents at follow-up had similar characteristics-almost 60% were female, median age was 47 years, two-thirds were physicians, and nearly 80% were HIV specialists. The percentage who reported recommending ART irrespective of CD4 count was higher at follow-up (15% versus 68%), as was the percentage who would initiate ART earlier for patients having unprotected sex with partners of unknown HIV status (64% versus 82%), and for those in HIV-discordant partnerships (75% versus 87%). In line with changing HIV treatment guidelines during 2010 to 2013, clinicians increasingly supported early ART for treatment and prevention. PMID- 27708119 TI - Getting Your Grumble Back. AB - PURPOSE OF STUDY: Viewing the surgical patient holistically within their environment of care, the bedside nurse is aware of the possible complication of postoperative paralytic ileus that can lead to patient discomfort and increased medical costs. Acute care nurses observed postoperative patients watching televised cooking shows on a consistent basis and questioned if there was a mind body link between bowel function and watching cooking shows. DESIGN OF STUDY: The study used an observational approach to examine the return of bowel sounds for postoperative patients. METHOD: Ninety-four patients that underwent abdominal surgery participated. A questionnaire was administered to capture total hours postsurgery of patient viewing cooking shows followed by chart review for age, height, weight, information specific to surgery, and documented first postsurgical flatus. FINDINGS: This study found that non-bariatric general surgery patients who watch cooking shows during hospitalization are significantly more likely to experience return of appetite and stomach sounds within 1 day postsurgery than patients who do not watch cooking shows. CONCLUSIONS: Based on the results of this study, the authors suggest that, when possible, patients who receive non-bariatric abdominal surgery be encouraged to watch cooking shows to experience the potential benefits such as early return of bowel functioning. PMID- 27708120 TI - Commercial Dairy Cow Milk microRNAs Resist Digestion under Simulated Gastrointestinal Tract Conditions. AB - BACKGROUND: MicroRNAs are small, gene-regulatory noncoding RNA species present in large amounts in milk, where they seem to be protected against degradative conditions, presumably because of their association with exosomes. OBJECTIVE: We monitored the relative stability of commercial dairy cow milk microRNAs during digestion and examined their associations with extracellular vesicles (EVs). METHODS: We used a computer-controlled, in vitro, gastrointestinal model TNO intestinal model-1 (TIM-1) and analyzed, by quantitative polymerase chain reaction, the concentration of 2 microRNAs within gastrointestinal tract compartments at different points in time. EVs within TIM-1 digested and nondigested samples were studied by immunoblotting, dynamic light scattering, quantitative polymerase chain reaction, and density measurements. RESULTS: A large quantity of dairy milk Bos taurus microRNA-223 (bta-miR-223) and bta-miR 125b (~109-1010 copies/300 mL milk) withstood digestion under simulated gastrointestinal tract conditions, with the stomach causing the most important decrease in microRNA amounts. A large quantity of these 2 microRNAs (~108-109 copies/300 mL milk) was detected in the upper small intestine compartments, which supports their potential bioaccessibility. A protocol optimized for the enrichment of dairy milk exosomes yielded a 100,000 * g pellet fraction that was positive for the exosomal markers tumor susceptibility gene-101 (TSG101), apoptosis-linked gene 2-interacting protein X (ALIX), and heat shock protein 70 (HSP70) and containing bta-miR-223 and bta-miR-125b. This approach, based on successive ultracentrifugation steps, also revealed the existence of ALIX-, HSP70 /low, and TSG101-/low EVs larger than exosomes and 2-6 times more enriched in bta miR-223 and bta-miR-125b (P < 0.05). CONCLUSIONS: Our findings indicate that commercial dairy cow milk contains numerous microRNAs that can resist digestion and are associated mostly with ALIX-, HSP70-/low, and TSG101-/low EVs. Our results support the existence of interspecies transfer of microRNAs mediated by milk consumption and challenge our current view of exosomes as the sole carriers of milk-derived microRNAs. PMID- 27708121 TI - Harmonization of Food-Frequency Questionnaires and Dietary Pattern Analysis in 4 Ethnically Diverse Birth Cohorts. AB - BACKGROUND: Canada is an ethnically diverse nation, which introduces challenges for health care providers tasked with providing evidence-based dietary advice. OBJECTIVES: We aimed to harmonize food-frequency questionnaires (FFQs) across 4 birth cohorts of ethnically diverse pregnant women to derive robust dietary patterns to investigate maternal and newborn outcomes. METHODS: The NutriGen Alliance comprises 4 prospective birth cohorts and includes 4880 Canadian mother infant pairs of predominantly white European [CHILD (Canadian Healthy Infant Longitudinal Development) and FAMILY (Family Atherosclerosis Monitoring In earLY life)], South Asian [START (SouTh Asian birth cohoRT)-Canada], or Aboriginal [ABC (Aboriginal Birth Cohort)] origins. CHILD used a multiethnic FFQ based on a previously validated instrument designed by the Fred Hutchinson Cancer Research Center, whereas FAMILY, START, and ABC used questionnaires specifically designed for use in white European, South Asian, and Aboriginal people, respectively. The serving sizes and consumption frequencies of individual food items within the 4 FFQs were harmonized and aggregated into 36 common food groups. Principal components analysis was used to identify dietary patterns that were internally validated against self-reported vegetarian status and externally validated against a modified Alternative Healthy Eating Index (mAHEI). RESULTS: Three maternal dietary patterns were identified-"plant-based," "Western," and "health conscious"-which collectively explained 29% of the total variability in eating habits observed in the NutriGen Alliance. These patterns were strongly associated with self-reported vegetarian status (OR: 3.85; 95% CI: 3.47, 4.29; r2 = 0.30, P < 0.001; for a plant-based diet), and average adherence to the plant-based diet was higher in participants in the fourth quartile of the mAHEI than in the first quartile (mean difference: 46.1%; r2 = 0.81, P < 0.001). CONCLUSION: Dietary data collected by using FFQs from ethnically diverse pregnant women can be harmonized to identify common dietary patterns to investigate associations between maternal dietary intake and health outcomes. PMID- 27708122 TI - Determination of Dietary Iron Requirements by Full Expression of Iron-Containing Enzymes in Various Tissues of Broilers. AB - BACKGROUND: The current dietary iron requirement (80 mg/kg) of broilers is mainly based on growth, hemoglobin concentration, or hematocrit data obtained in a few early studies; however, expressions of iron-containing enzymes might be more sensitive novel criteria to evaluate dietary iron requirements. OBJECTIVE: The objective of this study was to determine dietary iron requirements of broilers for the full expression of succinate dehydrogenase (SDH), catalase, and cytochrome c oxidase (COX) in various tissues. METHODS: A total of 336 1-d-old Arbor Acres male chicks were randomly assigned to 1 of 7 treatments with 6 replicates and fed a basal corn and soybean-meal diet (control, containing 67 mg Fe/kg) and the basal diet supplemented with 20, 40, 60, 80, 100, or 120 mg Fe/kg from FeSO4 ? 7H2O for 21 d. Regression analysis was performed to estimate the optimal dietary iron concentration with the use of broken-line or quadratic models. RESULTS: SDH activity in the liver and heart, COX and catalase activity in the liver, Sdh mRNA levels in the liver, and Cox mRNA levels in the liver and heart of broilers were affected (P < 0.027) by supplemental iron concentration, and increased quadratically (P < 0.004) as dietary iron concentration increased. Dietary iron requirements estimated on the basis of fitted broken-line or quadratic-curve models (P < 0.005) of the above indexes were 97-136 mg/kg. CONCLUSIONS: SDH activity in the liver and heart, COX and catalase activity in the liver, Sdh mRNA levels in the liver, and Cox mRNA levels in the liver and heart are, to our knowledge, new and sensitive criteria to evaluate the dietary iron requirements of broilers, and the dietary iron requirements would be 97-136 mg/kg to support the full expression of the above iron-containing enzymes in various tissues of broiler chicks from 1 to 21 d of age, which are higher than the current NRC iron requirement. PMID- 27708125 TI - Social comparisons and long-term rehabilitation for traumatic brain injury: A longitudinal study. AB - Little is known about social influences on long-term rehabilitation outcomes for traumatic brain injury, particularly social comparisons (i.e. self-evaluations relative to others). Patients in long-term rehabilitation ( n = 31) completed assessments at baseline and 1 year. Self-reported social comparison orientation was comparable to existing samples and showed stability over 1 year; affective responses to comparisons (e.g. frustration) were less stable. Social comparison orientation and affective responses were related to baseline executive and psychosocial functioning ( rs = 0.34-0.53) and predicted worse impairment and depression at 1 year ( ds = 0.67, 1.39). Greater attention to comparisons in long term rehabilitation could improve outcomes. PMID- 27708124 TI - Role of sweet and other flavours in liking and disliking of electronic cigarettes. AB - OBJECTIVE: To examine the extent to which the perception of sweet and other flavours is associated with liking and disliking of flavoured electronic cigarettes (e-cigarettes). METHODS: 31 participants (13 females/18 males; 12 sole/19 dual users) vaped 6 commercially available flavours of blu Tanks: Classic Tobacco (CT), Magnificent Menthol (MM), Cherry Crush (CC), Vivid Vanilla (VV), Pina Colada (PC) and Peach Schnapps (PS); all 'medium' strength, 12 mg/mL nicotine concentration. For each flavoured e-cigarette, participants first rated liking/disliking on the Labeled Hedonic Scale, followed by perceived intensities of sweetness, coolness, bitterness, harshness and specific flavour on the generalised version of the Labeled Magnitude Scale. The psychophysical testing was conducted individually in an environmental chamber. RESULTS: PC was perceived as sweetest and liked the most; CT was perceived as least sweet and liked the least. Across all flavours, liking was correlated with sweetness (r=0.31), coolness (r=0.25), bitterness (r=-0.25) and harshness (r=-0.29, all p<0.001). Specifically, liking was positively correlated with sweetness of PS (r=0.56, p=0.001) and PC (r=0.36, p=0.048); and with coolness of MM, CT and VV (r=0.41 0.52, p<0.05). In contrast, harshness was negatively correlated with liking for CC, PC and PS (r=0.37-0.40, p<0.05). In a multivariate model, sweetness had the greatest positive impact on liking followed by coolness; harshness had the greatest negative impact on liking. CONCLUSIONS: Our findings indicate that bitterness and harshness, most likely from nicotine, have negative impacts on the liking of e-cigarettes, but the addition of flavourants that elicit sweetness or coolness generally improves liking. The results suggest that flavours play an important role in e-cigarette preference and most likely use. PMID- 27708123 TI - Association between use of flavoured tobacco products and quit behaviours: findings from a cross-sectional survey of US adult tobacco users. AB - BACKGROUND: Non-menthol characterising flavours (eg, fruit, candy) are banned in cigarettes, yet are still permitted in non-cigarette tobacco (NCT) products. This study examined associations between first use and current use of flavoured tobacco products, and current flavoured tobacco use and quit behaviours. METHODS: A nationally representative, telephone-based survey completed in 2012 by 1443 US adult tobacco users asked about use of 9 tobacco products: cigarettes, e cigarettes, cigars, cigarillos, little filtered cigars, pipes, hookah, smokeless tobacco and snus. Ever users reported first use of flavoured products, while current users also reported current flavoured product use. Current users reported quit attempts made in the past year. Data were weighted to reflect the US adult tobacco user population. Logistic regression models were used to examine associations between first/current flavour use and quit behaviours. RESULTS: Over 70% of respondents reported first use of a flavoured tobacco product, while 54% reported current use of at least one flavoured product. Odds of current flavoured product use were greater among those who reported first use of a flavoured product (OR 14.82, 95% CI 9.96 to 22.06). First use of a flavoured product was associated with being a current tobacco user (OR 1.55, 95% CI 1.08 to 2.22). Compared to single product users, polytobacco users exhibited greater odds of reporting current use of flavoured products (OR 2.09, 95% CI 1.47 to 2.97). Forty four percent of current tobacco users reported a past-year quit attempt. Adjusted analyses among current NCT users of at least one flavoured tobacco product showed reduced odds of reporting a quit attempt. CONCLUSIONS: First use of a flavoured tobacco product was associated with current flavoured tobacco use and polytobacco use. Users of only flavoured NCT products exhibited reduced odds of reporting a quit attempt. Findings from this study reinforce the importance of flavoured product availability in the USA, which may have significant implications for efforts to reduce tobacco initiation and use at a population level. The relationship between characterising flavours and quit behaviours merits further exploration in longitudinal, population-based samples. PMID- 27708126 TI - 'It gets into your head as well as your body': The experiences of patients with cancer during oncology treatment with curative intent. AB - This study explored the psychosocial experiences of patients with cancer during the course of oncology treatment with curative intent. Our aim was to gather in depth insights into the shared elements of oncology treatment across a range of cancer types. A total of 10 individuals undergoing oncology treatment participated in semi-structured interviews. Six themes were identified using interpretative phenomenological analysis: diminished well-being, perceived role changes in intimate relationships, heightened awareness of limited time, a new order of priorities, taking things as they come and development of trust in health professionals. These themes indicate relevant areas of patients' well being, which might be enhanced through psychosocial support services. PMID- 27708127 TI - Creating Body Shapes From Verbal Descriptions by Linking Similarity Spaces. AB - Brief verbal descriptions of people's bodies (e.g., "curvy," "long-legged") can elicit vivid mental images. The ease with which these mental images are created belies the complexity of three-dimensional body shapes. We explored the relationship between body shapes and body descriptions and showed that a small number of words can be used to generate categorically accurate representations of three-dimensional bodies. The dimensions of body-shape variation that emerged in a language-based similarity space were related to major dimensions of variation computed directly from three-dimensional laser scans of 2,094 bodies. This relationship allowed us to generate three-dimensional models of people in the shape space using only their coordinates on analogous dimensions in the language based description space. Human descriptions of photographed bodies and their corresponding models matched closely. The natural mapping between the spaces illustrates the role of language as a concise code for body shape that captures perceptually salient global and local body features. PMID- 27708128 TI - Female advantage in verbal memory: Evidence of sex-specific cognitive reserve. AB - OBJECTIVE: We investigated sex differences in verbal memory across different levels of neural dysfunction, measured by temporal lobe glucose metabolic rates (TLGluMR). METHODS: Three hundred ninety controls and 672 participants with amnestic mild cognitive impairment (aMCI) and 254 with Alzheimer disease (AD) dementia from the Alzheimer's Disease Neuroimaging Initiative completed the Rey Auditory Verbal Learning Test (RAVLT) and [18F]-fluorodeoxyglucose-PET. Cross sectional analyses were conducted using linear regression to examine the sex by TLGluMR interaction on RAVLT performance in the overall sample and within diagnostic groups adjusting for age, education, and APOE epsilon4 genotype. RESULTS: Across groups, female sex and higher TLGluMR and their interaction were associated with better verbal memory (p values <= 0.005). The female advantage in verbal memory varied by TLGluMR such that the advantage was greatest among individuals with moderate to high TLGluMR and minimal or absent among individuals with lower TLGluMR. Diagnosis-stratified analyses revealed that this interaction was driven by the aMCI group (p values = 0.009). The interaction was not significant in control and AD dementia groups. CONCLUSIONS: Women show better verbal memory than men in aMCI despite similar levels of brain hypometabolism. The lifelong advantage that females show over males in verbal memory might represent a form of cognitive reserve that delays verbal memory decline until more advanced pathology, as indexed by TLGluMR. This issue is clinically important because verbal memory scores are used in diagnosing aMCI and AD dementia. PMID- 27708129 TI - Multifocal repetitive TMS for motor and mood symptoms of Parkinson disease: A randomized trial. AB - OBJECTIVE: To assess whether multifocal, high-frequency repetitive transcranial magnetic stimulation (rTMS) of motor and prefrontal cortex benefits motor and mood symptoms in patients with Parkinson disease (PD). METHODS: Patients with PD and depression were enrolled in this multicenter, double-blind, sham-controlled, parallel-group study of real or realistic (electric) sham rTMS. Patients were randomized to 1 of 4 groups: bilateral M1 ( + sham dorsolateral prefrontal cortex [DLPFC]), DLPFC ( + sham M1), M1 + DLPFC, or double sham. The TMS course consisted of 10 daily sessions of 2,000 stimuli for the left DLPFC and 1,000 stimuli for each M1 (50 * 4-second trains of 40 stimuli at 10 Hz). Patients were evaluated at baseline, at 1 week, and at 1, 3, and 6 months after treatment. Primary endpoints were changes in motor function assessed with the Unified Parkinson's Disease Rating Scale-III and in mood with the Hamilton Depression Rating Scale at 1 month. RESULTS: Of the 160 patients planned for recruitment, 85 were screened, 61 were randomized, and 50 completed all study visits. Real M1 rTMS resulted in greater improvement in motor function than sham at the primary endpoint (p < 0.05). There was no improvement in mood in the DLPFC group compared to the double-sham group, as well as no benefit to combining M1 and DLPFC stimulation for either motor or mood symptoms. CONCLUSIONS: In patients with PD with depression, M1 rTMS is an effective treatment of motor symptoms, while mood benefit after 2 weeks of DLPFC rTMS is not better than sham. Targeting both M1 and DLPFC in each rTMS session showed no evidence of synergistic effects. CLINICALTRIALSGOV IDENTIFIER: NCT01080794. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence that in patients with PD with depression, M1 rTMS leads to improvement in motor function while DLPFC rTMS does not lead to improvement in depression compared to sham rTMS. PMID- 27708130 TI - Distinct brain networks underlie cognitive dysfunction in Parkinson and Alzheimer diseases. AB - OBJECTIVE: To determine whether cognitive impairment in Parkinson disease (PD) and Alzheimer disease (AD) derives from the same network pathology. METHODS: We analyzed 18F-fluorodeoxyglucose PET scans from 40 patients with AD and 40 age matched healthy controls from the Alzheimer's Disease Neuroimaging Initiative and scanned an additional 10 patients with AD and 10 healthy controls at The Feinstein Institute for Medical Research to derive an AD-related metabolic pattern (ADRP) analogous to our previously established PD cognition-related pattern (PDCP) and PD motor-related pattern (PDRP). We computed individual subject expression values for ADRP and PDCP in 89 patients with PD and correlated summary scores for cognitive functioning with network expression. We also evaluated changes in ADRP and PDCP expression in a separate group of 15 patients with PD scanned serially over a 4-year period. RESULTS: Analysis revealed a significant AD-related metabolic topography characterized by covarying metabolic reductions in the hippocampus, parahippocampal gyrus, and parietal and temporal association regions. Expression of ADRP, but not PDCP, was elevated in both AD groups and correlated with worse cognitive summary scores. Patients with PD showed slight ADRP expression, due to topographic overlap with the network underlying PD motor-related pattern degeneration, but only their PDCP expression values increased as cognitive function and executive performance declined. Longitudinal data in PD disclosed an analogous dissociation of network expression. CONCLUSIONS: Cognitive dysfunction in PD is associated with a specific brain network that is largely spatially and functionally distinct from that seen in relation to AD. PMID- 27708135 TI - Hobnail Hemangioma With an Unusual Clinical Presentation. AB - Hobnail hemangioma, also known as targetoid hemosiderotic hemangioma, is an uncommon vascular proliferation that clinically presents as a small solitary red to purple papule or macule, located on the limbs or trunk. Multiple lesions and atypical locations have been described. Histopathologically, it exhibits a biphasic pattern, with dilated vessels in the superficial dermis and angulated vessels in the deeper dermis, with endothelial cells that show a hobnail appearance. There is controversy about the histogenetic origin of hobnail hemangioma, although recent studies support that it is a lymphatic malformation. The investigators report the case of a 41-year-old man with an irregular lesion, red to purple in color, with a maximum diameter of 4 cm, on the scalp. The location and in particular the clinical appearance are uncommon. Immunohistochemical analysis showed negativity for WT1 and focal positivity for D2-40. Clinical-pathologic correlation acquires particular importance in the case of lesions with atypical clinical presentation. PMID- 27708136 TI - Glutathione depletion activates the yeast vacuolar transient receptor potential channel, Yvc1p, by reversible glutathionylation of specific cysteines. AB - Glutathione depletion and calcium influx into the cytoplasm are two hallmarks of apoptosis. We have been investigating how glutathione depletion leads to apoptosis in yeast. We show here that glutathione depletion in yeast leads to the activation of two cytoplasmically inward-facing channels: the plasma membrane, Cch1p, and the vacuolar calcium channel, Yvc1p. Deletion of these channels partially rescues cells from glutathione depletion-induced cell death. Subsequent investigations on the Yvc1p channel, a homologue of the mammalian TRP channels, revealed that the channel is activated by glutathionylation. Yvc1p has nine cysteine residues, of which eight are located in the cytoplasmic regions and one on the transmembrane domain. We show that three of these cysteines, Cys-17, Cys 79, and Cys-191, are specifically glutathionylated. Mutation of these cysteines to alanine leads to a loss in glutathionylation and a concomitant loss in calcium channel activity. We further investigated the mechanism of glutathionylation and demonstrate a role for the yeast glutathione S-transferase Gtt1p in glutathionylation. Yvc1p is also deglutathionylated, and this was found to be mediated by the yeast thioredoxin, Trx2p. A model for redox activation and deactivation of the yeast Yvc1p channel is presented. PMID- 27708137 TI - An NXF1 mRNA with a retained intron is expressed in hippocampal and neocortical neurons and is translated into a protein that functions as an Nxf1 cofactor. AB - The Nxf1 protein is a major nuclear export receptor for the transport of mRNA, and it also is essential for export of retroviral mRNAs with retained introns. In the latter case, it binds to RNA elements known as constitutive transport elements (CTEs) and functions in conjunction with a cofactor known as Nxt1. The NXF1 gene also regulates expression of its own intron-containing RNA through the use of a functional CTE within intron 10. mRNA containing this intron is exported to the cytoplasm, where it can be translated into the 356-amino acid short Nxf1(sNxf1) protein, despite the fact that it is a prime candidate for nonsense mediated decay (NMD). Here we demonstrate that sNxf1 is highly expressed in nuclei and dendrites of hippocampal and neocortical neurons in rodent brain. Additionally, we show that sNxf1 localizes in RNA granules in neurites of differentiated N2a mouse neuroblastoma cells, where it shows partial colocalization with Staufen2 isoform SS, a protein known to play a role in dendritic mRNA trafficking. We also show that sNxf1 forms heterodimers in conjunction with the full-length Nxf1 and that sNxf1 can replace Nxt1 to enhance the expression of CTE-containing mRNA and promote its association with polyribosomes. PMID- 27708138 TI - GOLPH3 drives cell migration by promoting Golgi reorientation and directional trafficking to the leading edge. AB - The mechanism of directional cell migration remains an important problem, with relevance to cancer invasion and metastasis. GOLPH3 is a common oncogenic driver of human cancers, and is the first oncogene that functions at the Golgi in trafficking to the plasma membrane. Overexpression of GOLPH3 is reported to drive enhanced cell migration. Here we show that the phosphatidylinositol-4 phosphate/GOLPH3/myosin 18A/F-actin pathway that is critical for Golgi-to-plasma membrane trafficking is necessary and limiting for directional cell migration. By linking the Golgi to the actin cytoskeleton, GOLPH3 promotes reorientation of the Golgi toward the leading edge. GOLPH3 also promotes reorientation of lysosomes (but not other organelles) toward the leading edge. However, lysosome function is dispensable for migration and the GOLPH3 dependence of lysosome movement is indirect, via GOLPH3's effect on the Golgi. By driving reorientation of the Golgi to the leading edge and driving forward trafficking, particularly to the leading edge, overexpression of GOLPH3 drives trafficking to the leading edge of the cell, which is functionally important for directional cell migration. Our identification of a novel pathway for Golgi reorientation controlled by GOLPH3 provides new insight into the mechanism of directional cell migration with important implications for understanding GOLPH3's role in cancer. PMID- 27708139 TI - Regulation of GPCR expression through an interaction with CCT7, a subunit of the CCT/TRiC complex. AB - Mechanisms that prevent aggregation and promote folding of nascent G protein coupled receptors (GPCRs) remain poorly understood. We identified chaperonin containing TCP-1 subunit eta (CCT7) as an interacting partner of the beta-isoform of thromboxane A2 receptor (TPbeta) by yeast two-hybrid screening. CCT7 coimmunoprecipitated with overexpressed TPbeta and beta2-adrenergic receptor (beta2AR) in HEK 293 cells, but also with endogenous beta2AR. CCT7 depletion by small interfering RNA reduced total and cell-surface expression of both receptors and caused redistribution of the receptors to juxtanuclear aggresomes, significantly more so for TPbeta than beta2AR. Interestingly, Hsp90 coimmunoprecipitated with beta2AR but virtually not with TPbeta, indicating that nascent GPCRs can adopt alternative folding pathways. In vitro pull-down assays showed that both receptors can interact directly with CCT7 through their third intracellular loops and C-termini. We demonstrate that Trp334 in the TPbeta C terminus is critical for the CCT7 interaction and plays an important role in TPbeta maturation and cell-surface expression. Of note, introducing a tryptophan in the corresponding position of the TPalpha isoform confers the CCT7-binding and maturation properties of TPbeta. We show that an interaction with a subunit of the CCT/TCP-1 ring complex (TRiC) chaperonin complex is involved in regulating aggregation of nascent GPCRs and in promoting their proper maturation and expression. PMID- 27708140 TI - The cAMP pathway regulates mRNA decay through phosphorylation of the RNA-binding protein TIS11b/BRF1. AB - TPA-inducible sequence 11b/butyrate response factor 1 (TIS11b/BRF1) belongs to the tristetraprolin (TTP) family of zinc-finger proteins, which bind to mRNAs containing AU-rich elements in their 3'-untranslated region and target them for degradation. Regulation of TTP family function through phosphorylation by p38 MAP kinase and Akt/protein kinase B signaling pathways has been extensively studied. In contrast, the role of cAMP-dependent protein kinase (PKA) in the control of TTP family activity in mRNA decay remains largely unknown. Here we show that PKA activation induces TIS11b gene expression and protein phosphorylation. Site directed mutagenesis combined with kinase assays and specific phosphosite immunodetection identified Ser-54 (S54) and Ser-334 (S334) as PKA target amino acids in vitro and in vivo. Phosphomimetic mutation of the C-terminal S334 markedly increased TIS11b half-life and, unexpectedly, enhanced TIS11b activity on mRNA decay. Examination of protein-protein interactions between TIS11b and components of the mRNA decay machinery revealed that mimicking phosphorylation at S334 enhances TIS11b interaction with the decapping coactivator Dcp1a, while preventing phosphorylation at S334 potentiates its interaction with the Ccr4-Not deadenylase complex subunit Cnot1. Collectively our findings establish for the first time that cAMP-elicited phosphorylation of TIS11b plays a key regulatory role in its mRNA decay-promoting function. PMID- 27708141 TI - madSTORM: a superresolution technique for large-scale multiplexing at single molecule accuracy. AB - Investigation of heterogeneous cellular structures using single-molecule localization microscopy has been limited by poorly defined localization accuracy and inadequate multiplexing capacity. Using fluorescent nanodiamonds as fiducial markers, we define and achieve localization precision required for single molecule accuracy in dSTORM images. Coupled with this advance, our new multiplexing strategy, madSTORM, allows accurate targeting of multiple molecules using sequential binding and elution of fluorescent antibodies. madSTORM is used on an activated T-cell to localize 25 epitopes, 14 of which are on components of the same multimolecular T-cell receptor complex. We obtain an average localization precision of 2.6 nm, alignment error of 2.0 nm, and <0.01% cross talk. Combining these technical advances affords the ability to move beyond obtaining superresolved structures to defining spatial relationships among constituent molecules within structures.

AB - PURPOSE: To report a Bayesian network meta-analysis of randomized controlled trials (RCTs) comparing bare metal stents (BMS), paclitaxel-coated balloons (PCBs), and drug-eluting stents (DES) with balloon angioplasty (BA) or with each other in the infrapopliteal arteries. METHODS: Sixteen RCTs comprising 1805 patients with 1-year median follow-up were analyzed. Bayesian random effects binomial models were employed (WinBUGS). Relative treatment effects were expressed as odds ratios (ORs) with 95% credible intervals (CrI), and the cumulative rank probabilities were calculated to provide hierarchies of competing treatments. Quality of evidence (QoE) was assessed with the GRADE (grading of recommendations assessment, development, and evaluation) system. Sensitivity, heterogeneity, and consistency analyses were performed. RESULTS: There was high QoE that infrapopliteal DES significantly reduced restenosis compared with BMS (OR 0.26, 95% CrI 0.12 to 0.51) and BA (OR 0.22, 95% CrI 0.11 to 0.45). Likewise, DES significantly reduced target lesion revascularization (TLR) compared with BA (OR 0.41, 95% CrI 0.22 to 0.75) and BMS (OR 0.26, 95% CrI 0.15 to 0.45). Paclitaxel-coated balloons also reduced TLR compared with BA (OR 0.55, 95% CrI 0.34 to 0.90) and BMS (OR 0.35, 95% CrI 0.18 to 0.67), but QoE was low to moderate. BA had lower TLR than BMS (OR 0.63, 95% CrI 0.40 to 0.99) with high QoE. DES was the only treatment that significantly reduced limb amputations compared with BA (OR 0.58, 95% CrI 0.35 to 0.96), PCB (OR 0.51, 95% CrI 0.26 to 0.98), or BMS (OR 0.38, 95% CrI 0.19 to 0.72) with moderate to high QoE. DES also significantly improved wound healing compared with BA (OR 2.02, 95% CrI 1.01 to 4.07) or BMS (OR 3.45, 95% CrI 1.41 to 8.73) with high QoE. Results were stable on sensitivity and meta-regression analyses without any significant publication bias or inconsistency. CONCLUSION: Infrapopliteal DES were associated with significantly lower rates of restenosis, TLR, and amputations and improved wound healing compared to BA and BMS. DES also significantly reduced amputations compared with PCB. PMID- 27708146 TI - Migratory life histories explain the extreme egg-size dimorphism of Eudyptes penguins. AB - When successive stages in the life history of an animal directly overlap, physiological conflicts can arise resulting in carryover effects from one stage to another. The extreme egg-size dimorphism (ESD) of Eudyptes penguins, where the first-laid A-egg is approximately 18-57% smaller than the second-laid B-egg, has interested researchers for decades. Recent studies have linked variation in this trait to a carryover effect of migration that limits the physiology of yolk production and egg sizes. We assembled data on ESD and estimates of migration reproduction overlap in penguin species and use phylogenetic methods to test the idea that migration-reproduction overlap explains variation in ESD. We show that migration overlap is generally restricted to Eudyptes relative to non-Eudyptes penguins, and that this overlap (defined as the amount of time that egg production occurs on land versus at sea during homeward migration) is significantly and positively correlated with the degree of ESD in Eudyptes In the non-Eudyptes species, however, ESD was unrelated to migration overlap as these species mostly produce their clutches on land. Our results support the recent hypothesis that extreme ESD of Eudyptes penguins evolved, in part, as a response to selection for a pelagic overwinter migration behaviour. This resulted in a temporal overlap with, and thus a constraint on, the physiology of follicle development, leading to smaller A-egg size and greater ESD.

AB - There is considerable controversy about the existence, extent and adaptive value of integrated multimodal memory in non-human animals. Building on prior results showing that wild capuchin monkeys in Argentina appear to recall both the location and amount of food at patches they had previously visited, I tested whether they also track and use elapsed time as a basis for decisions about which feeding patches to visit. I presented them with an experimental array of eight feeding sites, at each of which food rewards increased with increasing elapsed time since the previous visit, similar to the pattern of ripe fruit accumulation in natural feeding trees. Over the course of 68 days, comprising two distinct renewal rate treatments, one group repeatedly visited sites in the feeding array, generating 212 valid choices between sites. Comparison of observations against simulated movements and multinomial statistical models shows that the monkeys' choices were most consistent with dynamic memory for elapsed time specific to each of the eight sites. Thus, it appears that capuchin monkeys possess and use integrated memories of prior food patch use, including where the patch is relative to their current location, how productive the patch is and how long it has been since they last visited the patch. Natural selection to use such integrated memories in foraging tasks may provide an ecologically relevant basis for the evolution of complex intelligence in primates. PMID- 27708147 TI - Evolution of bacterial recombinase A (recA) in eukaryotes explained by addition of genomic data of key microbial lineages. AB - Recombinase enzymes promote DNA repair by homologous recombination. The genes that encode them are ancestral to life, occurring in all known dominions: viruses, Eubacteria, Archaea and Eukaryota. Bacterial recombinases are also present in viruses and eukaryotic groups (supergroups), presumably via ancestral events of lateral gene transfer. The eukaryotic recA genes have two distinct origins (mitochondrial and plastidial), whose acquisition by eukaryotes was possible via primary (bacteria-eukaryote) and/or secondary (eukaryote-eukaryote) endosymbiotic gene transfers (EGTs). Here we present a comprehensive phylogenetic analysis of the recA genealogy, with substantially increased taxonomic sampling in the bacteria, viruses, eukaryotes and a special focus on the key eukaryotic supergroup Amoebozoa, earlier represented only by Dictyostelium We demonstrate that several major eukaryotic lineages have lost the bacterial recombinases (including Opisthokonta and Excavata), whereas others have retained them (Amoebozoa, Archaeplastida and the SAR-supergroups). When absent, the bacterial recA homologues may have been lost entirely (secondary loss of canonical mitochondria) or replaced by other eukaryotic recombinases. RecA proteins have a transit peptide for organellar import, where they act. The reconstruction of the RecA phylogeny with its EGT events presented here retells the intertwined evolutionary history of eukaryotes and bacteria, while further illuminating the events of endosymbiosis in eukaryotes by expanding the collection of widespread genes that provide insight to this deep history. PMID- 27708148 TI - Genetic basis of priority effects: insights from nectar yeast. AB - Priority effects, in which the order of species arrival dictates community assembly, can have a major influence on species diversity, but the genetic basis of priority effects remains unknown. Here, we suggest that nitrogen scavenging genes previously considered responsible for starvation avoidance may drive priority effects by causing rapid resource depletion. Using single-molecule sequencing, we de novo assembled the genome of the nectar-colonizing yeast, Metschnikowia reukaufii, across eight scaffolds and complete mitochondrion, with gap-free coverage over gene spaces. We found a high rate of tandem gene duplication in this genome, enriched for nitrogen metabolism and transport. Both high-capacity amino acid importers, GAP1 and PUT4, present as tandem gene arrays, were highly expressed in synthetic nectar and regulated by the availability and quality of amino acids. In experiments with competitive nectar yeast, Candida rancensis, amino acid addition alleviated suppression of C. rancensis by early arrival of M. reukaufii, corroborating that amino acid scavenging may contribute to priority effects. Because niche pre-emption via rapid resource depletion may underlie priority effects in a broad range of microbial, plant and animal communities, nutrient scavenging genes like the ones we considered here may be broadly relevant to understanding priority effects. PMID- 27708149 TI - Urban warming reduces aboveground carbon storage. AB - A substantial amount of global carbon is stored in mature trees. However, no experiments to date test how warming affects mature tree carbon storage. Using a unique, citywide, factorial experiment, we investigated how warming and insect herbivory affected physiological function and carbon sequestration (carbon stored per year) of mature trees. Urban warming increased herbivorous arthropod abundance on trees, but these herbivores had negligible effects on tree carbon sequestration. Instead, urban warming was associated with an estimated 12% loss of carbon sequestration, in part because photosynthesis was reduced at hotter sites. Ecosystem service assessments that do not consider urban conditions may overestimate urban tree carbon storage. Because urban and global warming are becoming more intense, our results suggest that urban trees will sequester even less carbon in the future. PMID- 27708150 TI - Temporal patterns of local adaptation in soil pseudomonads. AB - Strong divergent selection leading to local adaptation is often invoked to explain the staggering diversity of bacteria in microbial ecosystems. However, examples of specialization by bacterial clones to alternative niches in nature are rare. Here, we investigate the extent of local adaptation in natural isolates of pseudomonads and their relatives to their soil environments across both space and time. Though most isolates grew well in most environments, patchily distributed low-quality environments were found to drive specialization. In contrast to experimental evolution work on microbial adaptation, temporal adaptation was stronger than spatial adaptation among the isolates and environments we sampled. Time-shift analysis of fitness across two seasons of growth revealed an unexpectedly strong effect of preadaptation. This pattern of apparent future adaptation may be caused by unknown abiotic properties of these environments, phages, bacterial competitors or general mechanisms of ecological niche release, and warrants future study. PMID- 27708152 TI - Pyrodiversity promotes avian diversity over the decade following forest fire. AB - An emerging hypothesis in fire ecology is that pyrodiversity increases species diversity. We test whether pyrodiversity-defined as the standard deviation of fire severity-increases avian biodiversity at two spatial scales, and whether and how this relationship may change in the decade following fire. We use a dynamic Bayesian community model applied to a multi-year dataset of bird surveys at 1106 points sampled across 97 fires in montane California. Our results provide strong support for a positive relationship between pyrodiversity and bird diversity. This relationship interacts with time since fire, with pyrodiversity having a greater effect on biodiversity at 10 years post-fire than at 1 year post-fire. Immediately after fires, patches of differing burn severities hold similar bird communities, but over the ensuing decade, bird assemblages within patches of contrasting severities differentiate. When evaluated at the scale of individual fires, fires with a greater heterogeneity of burn severities hold substantially more species. High spatial heterogeneity in severity, sometimes called 'mixed severity fire', is a natural part of wildfire regimes in western North America, but may be jeopardized by climate change and a legacy of fire suppression. Forest management that encourages mixed-severity fire may be critical for sustaining biodiversity across fire-prone landscapes. PMID- 27708151 TI - Blastoderm segmentation in Oncopeltus fasciatus and the evolution of insect segmentation mechanisms. AB - Segments are formed simultaneously in the blastoderm of the fly Drosophila melanogaster through a hierarchical cascade of interacting transcription factors. Conversely, in many insects and in all non-insect arthropods most segments are formed sequentially from the posterior. We have looked at segmentation in the milkweed bug Oncopeltus fasciatus. Posterior segments are formed sequentially, through what is probably the ancestral arthropod mechanism. Formation of anterior segments bears many similarities to the Drosophila segmentation mode. These segments appear nearly simultaneously in the blastoderm, via a segmentation cascade that involves orthologues of Drosophila gap genes working through a functionally similar mechanism. We suggest that simultaneous blastoderm segmentation evolved at or close to the origin of holometabolous insects, and formed the basis for the evolution of the segmentation mode seen in Drosophila We discuss the changes in segmentation mechanisms throughout insect evolution, and suggest that the appearance of simultaneous segmentation as a novel feature of holometabolous insects may have contributed to the phenomenal success of this group. PMID- 27708153 TI - Density-dependent changes in effective area occupied for sea-bottom-associated marine fishes. AB - The spatial distribution of marine fishes can change for many reasons, including density-dependent distributional shifts. Previous studies show mixed support for either the proportional-density model (PDM; no relationship between abundance and area occupied, supported by ideal-free distribution theory) or the basin model (BM; positive abundance-area relationship, supported by density-dependent habitat selection theory). The BM implies that fishes move towards preferred habitat as the population declines. We estimate the average relationship using bottom trawl data for 92 fish species from six marine regions, to determine whether the BM or PDM provides a better description for sea-bottom-associated fishes. We fit a spatio-temporal model and estimate changes in effective area occupied and abundance, and combine results to estimate the average abundance-area relationship as well as variability among taxa and regions. The average relationship is weak but significant (0.6% increase in area for a 10% increase in abundance), whereas only a small proportion of species-region combinations show a negative relationship (i.e. shrinking area when abundance increases). Approximately one-third of combinations (34.6%) are predicted to increase in area more than 1% for every 10% increase in abundance. We therefore infer that population density generally changes faster than effective area occupied during abundance changes. Gadiformes have the strongest estimated relationship (average 1.0% area increase for every 10% abundance increase) followed by Pleuronectiformes and Scorpaeniformes, and the Eastern Bering Sea shows a strong relationship between abundance and area occupied relative to other regions. We conclude that the BM explains a small but important portion of spatial dynamics for sea-bottom-associated fishes, and that many individual populations merit cautious management during population declines, because a compressed range may increase the efficiency of harvest. PMID- 27708154 TI - Dynamic sinking behaviour in marine phytoplankton: rapid changes in buoyancy may aid in nutrient uptake. AB - Phytoplankton sinking is an important property that can determine community composition in the photic zone and material loss to the deep ocean. To date, studies of diatom suspension have relied on bulk measurements with assumptions that bulk rates adequately capture the essential characteristics of diatom sinking. However, recent work has illustrated that individual diatom sinking rates vary considerably from the mean bulk rate. In this study, we apply high resolution optical techniques, individual-based observations of diatom sinking and a recently developed method of flow visualization around freely sinking cells. The results show that in both field samples and laboratory cultures, some large species of centric diatoms are capable of a novel behaviour, whereby cells undergo bursts of rapid sinking that alternate with near-zero sinking rates on the timescales of seconds. We also demonstrate that this behaviour is under direct metabolic control of the cell. We discuss these results in the context of implications for nutrient flux to the cell surface. While nutrient flux in large diatoms increases during fast sinking, current mass transport models cannot incorporate the unsteady sinking behaviour observed in this study. However, large diatoms appear capable of benefiting from the enhanced nutrient flux to their surface during rapid sinking even during brief intervening periods of near-zero sinking rates.

PMID- 27708155 TI - Strong influence of palaeoclimate on the structure of modern African mammal communities. AB - Ecological research often assumes that species are adapted to their current climatic environments. However, climate fluctuations over geologic timescales have influenced species dispersal and extinction, which in turn may affect community structure. Modern community structure is likely to be the product of both palaeoclimate and modern climate, with the relative degrees of influence of past and present climates unknown. Here, we assessed the influence of climate at different time periods on the phylogenetic and functional trait structure of 203 African mammal communities. We found that the climate of the mid-Holocene (approx. 6000 years ago) and Last Glacial Maximum (approx. 22 000 years ago) were frequently better predictors of community structure than modern climate for mammals overall, carnivorans and ungulates. Primate communities were more strongly influenced by modern climate than palaeoclimate. Overall, community structure of African mammals appears to be related to the ecological flexibility of the groups considered here and the regions of continental Africa that they occupy. Our results indicate that the future redistribution, expansion and contraction of particular biomes due to human activity, such as climate and land use change, will differentially affect mammal groups that vary in their sensitivity to environmental change. PMID- 27708157 TI - Amyloid-beta effects on synapses and memory require AMPA receptor subunit GluA3. AB - Amyloid-beta (Abeta) is a prime suspect for causing cognitive deficits during the early phases of Alzheimer's disease (AD). Experiments in AD mouse models have shown that soluble oligomeric clusters of Abeta degrade synapses and impair memory formation. We show that all Abeta-driven effects measured in these mice depend on AMPA receptor (AMPAR) subunit GluA3. Hippocampal neurons that lack GluA3 were resistant against Abeta-mediated synaptic depression and spine loss. In addition, Abeta oligomers blocked long-term synaptic potentiation only in neurons that expressed GluA3. Furthermore, although Abeta-overproducing mice showed significant memory impairment, memories in GluA3-deficient congenics remained unaffected. These experiments indicate that the presence of GluA3 containing AMPARs is critical for Abeta-mediated synaptic and cognitive deficits. PMID- 27708158 TI - One-dimensional nanowires of pseudoboehmite (aluminum oxyhydroxide gamma-AlOOH). AB - We report the discovery of a 1D crystalline structure of aluminum oxyhydroxide. It was found in a commercial product of fibrous pseudoboehmite (PB), gamma-AlOOH, synthesized easily with low cost. The thinnest fiber found was a ribbon-like structure of only two layers of an Al-O octahedral double sheet having a submicrometer length along its c axis and 0.68-nm thickness along its b axis. This thickness is only slightly larger than half of the lattice parameter of the b-axis unit cell of the boehmite crystal (b/2 = 0.61 nm). Moreover, interlayer splittings having an average width of 1 nm inside the fibrous PB are found. These wider interlayer spaces may have intercalation of water, which is suggested by density functional theory (DFT) calculation. The fibers appear to grow as almost isolated individual filaments in aqueous Al-hydroxide sols and the growth direction of fibrous PB is always along its c axis. PMID- 27708159 TI - Insulin resistance and diabetes caused by genetic or diet-induced KBTBD2 deficiency in mice. AB - We describe a metabolic disorder characterized by lipodystrophy, hepatic steatosis, insulin resistance, severe diabetes, and growth retardation observed in mice carrying N-ethyl-N-nitrosourea (ENU)-induced mutations. The disorder was ascribed to a mutation of kelch repeat and BTB (POZ) domain containing 2 (Kbtbd2) and was mimicked by a CRISPR/Cas9-targeted null allele of the same gene. Kbtbd2 encodes a BTB-Kelch family substrate recognition subunit of the Cullin-3-based E3 ubiquitin ligase. KBTBD2 targeted p85alpha, the regulatory subunit of the phosphoinositol-3-kinase (PI3K) heterodimer, causing p85alpha ubiquitination and proteasome-mediated degradation. In the absence of KBTBD2, p85alpha accumulated to 30-fold greater levels than in wild-type adipocytes, and excessive p110-free p85alpha blocked the binding of p85alpha-p110 heterodimers to IRS1, interrupting the insulin signal. Both transplantation of wild-type adipose tissue and homozygous germ line inactivation of the p85alpha-encoding gene Pik3r1 rescued diabetes and hepatic steatosis phenotypes of Kbtbd2-/- mice. Kbtbd2 was down regulated in diet-induced obese insulin-resistant mice in a leptin-dependent manner. KBTBD2 is an essential regulator of the insulin-signaling pathway, modulating insulin sensitivity by limiting p85alpha abundance. PMID- 27708160 TI - Environmental and genetic factors support the dissociation between alpha synuclein aggregation and toxicity. AB - Synucleinopathies are a group of progressive disorders characterized by the abnormal aggregation and accumulation of alpha-synuclein (aSyn), an abundant neuronal protein that can adopt different conformations and biological properties. Recently, aSyn pathology was shown to spread between neurons in a prion-like manner. Proteins like aSyn that exhibit self-propagating capacity appear to be able to adopt different stable conformational states, known as protein strains, which can be modulated both by environmental and by protein intrinsic factors. Here, we analyzed these factors and found that the unique combination of the neurodegeneration-related metal copper and the pathological H50Q aSyn mutation induces a significant alteration in the aggregation properties of aSyn. We compared the aggregation of WT and H50Q aSyn with and without copper, and assessed the effects of the resultant protein species when applied to primary neuronal cultures. The presence of copper induces the formation of structurally different and less-damaging aSyn aggregates. Interestingly, these aggregates exhibit a stronger capacity to induce aSyn inclusion formation in recipient cells, which demonstrates that the structural features of aSyn species determine their effect in neuronal cells and supports a lack of correlation between toxicity and inclusion formation. In total, our study provides strong support in favor of the hypothesis that protein aggregation is not a primary cause of cytotoxicity. PMID- 27708163 TI - Scale-free channeling patterns near the onset of erosion of sheared granular beds. AB - Erosion shapes our landscape and occurs when a sufficient shear stress is exerted by a fluid on a sedimented layer. What controls erosion at a microscopic level remains debated, especially near the threshold forcing where it stops. Here we study, experimentally, the collective dynamics of the moving particles, using a setup where the system spontaneously evolves toward the erosion onset. We find that the spatial organization of the erosion flux is heterogeneous in space and occurs along channels of local flux sigma whose distribution displays scaling near threshold and follows [Formula: see text], where J is the mean erosion flux. Channels are strongly correlated in the direction of forcing but not in the transverse direction. We show that these results quantitatively agree with a model where the dynamics is governed by the competition of disorder (which channels mobile particles) and particle interactions (which reduces channeling). These observations support that, for laminar flows, erosion is a dynamical phase transition that shares similarity with the plastic depinning transition occurring in dirty superconductors. The methodology we introduce here could be applied to probe these systems as well. PMID- 27708162 TI - The Architecture of Trypanosoma brucei editosomes. AB - Uridine insertion and deletion RNA editing generates functional mitochondrial mRNAs in Trypanosoma brucei Editing is catalyzed by three distinct ~20S editosomes that have a common set of 12 proteins, but are typified by mutually exclusive RNase III endonucleases with distinct cleavage specificities and unique partner proteins. Previous studies identified a network of protein-protein interactions among a subset of common editosome proteins, but interactions among the endonucleases and their partner proteins, and their interactions with common subunits were not identified. Here, chemical cross-linking and mass spectrometry, comparative structural modeling, and genetic and biochemical analyses were used to define the molecular architecture and subunit organization of purified editosomes. We identified intra- and interprotein cross-links for all editosome subunits that are fully consistent with editosome protein structures and previously identified interactions, which we validated by genetic and biochemical studies. The results were used to create a highly detailed map of editosome protein domain proximities, leading to identification of molecular interactions between subunits, insights into the functions of noncatalytic editosome proteins, and a global understanding of editosome architecture. PMID- 27708161 TI - Arabidopsis small nucleolar RNA monitors the efficient pre-rRNA processing during ribosome biogenesis. AB - Ribosome production in eukaryotes requires the complex and precise coordination of several hundred assembly factors, including many small nucleolar RNAs (snoRNAs). However, at present, the distinct role of key snoRNAs in ribosome biogenesis remains poorly understood in higher plants. Here we report that a previously uncharacterized C (RUGAUGA)/D (CUGA) type snoRNA, HIDDEN TREASURE 2 (HID2), acts as an important regulator of ribosome biogenesis through a snoRNA rRNA interaction. Nucleolus-localized HID2 is actively expressed in Arabidopsis proliferative tissues, whereas defects in HID2 cause a series of developmental defects reminiscent of ribosomal protein mutants. HID2 associates with the precursor 45S rRNA and promotes the efficiency and accuracy of pre-rRNA processing. Intriguingly, disrupting HID2 in Arabidopsis appears to impair the integrity of 27SB, a key pre-rRNA intermediate that generates 25S and 5.8S rRNA and is known to be vital for the synthesis of the 60S large ribosomal subunit and also produces an imbalanced ribosome profile. Finally, we demonstrate that the antisense-box of HID2 is both functionally essential and highly conserved in eukaryotes. Overall, our study reveals the vital and possibly conserved role of a snoRNA in monitoring the efficiency of pre-rRNA processing during ribosome biogenesis. PMID- 27708164 TI - Superantigens hyperinduce inflammatory cytokines by enhancing the B7-2/CD28 costimulatory receptor interaction. AB - Full T-cell activation requires interaction between the costimulatory receptors B7-2 and CD28. By binding CD28, bacterial superantigens elicit harmful inflammatory cytokine overexpression through an unknown mechanism. We show that, by engaging not only CD28 but also its coligand B7-2 directly, superantigens potently enhance the avidity between B7-2 and CD28, inducing thereby T-cell hyperactivation. Using the same 12-aa beta-strand-hinge-alpha-helix domain, superantigens engage both B7-2 and CD28 at their homodimer interfaces, areas remote from where these coreceptors interact, implying that inflammatory signaling can be controlled through the receptor homodimer interfaces. Short B7-2 dimer interface mimetic peptides bind diverse superantigens, prevent superantigen binding to cell-surface B7-2 or CD28, attenuate inflammatory cytokine overexpression, and protect mice from lethal superantigen challenge. Thus, superantigens induce a cytokine storm not only by mediating the interaction between MHC-II molecule and T-cell receptor but also, critically, by promoting B7 2/CD28 coreceptor engagement, forcing the principal costimulatory axis to signal excessively. Our results reveal a role for B7-2 as obligatory receptor for superantigens. B7-2 homodimer interface mimotopes prevent superantigen lethality by blocking the superantigen-host costimulatory receptor interaction. PMID- 27708165 TI - Accumulation of specific sterol precursors targets a MAP kinase cascade mediating cell-cell recognition and fusion. AB - Sterols are vital components of eukaryotic cell membranes. Defects in sterol biosynthesis, which result in the accumulation of precursor molecules, are commonly associated with cellular disorders and disease. However, the effects of these sterol precursors on the metabolism, signaling, and behavior of cells are only poorly understood. In this study, we show that the accumulation of only ergosterol precursors with a conjugated double bond in their aliphatic side chain specifically disrupts cell-cell communication and fusion in the fungus Neurospora crassa Genetically identical germinating spores of this fungus undergo cell-cell fusion, thereby forming a highly interconnected supracellular network during colony initiation. Before fusion, the cells use an unusual signaling mechanism that involves the coordinated and alternating switching between signal sending and receiving states of the two fusion partners. Accumulation of only ergosterol precursors with a conjugated double bond in their aliphatic side chain disrupts this coordinated cell-cell communication and suppresses cell fusion. These specific sterol precursors target a single ERK-like mitogen-activated protein (MAP) kinase (MAK-1)-signaling cascade, whereas a second MAP kinase pathway (MAK 2), which is also involved in cell fusion, is unaffected. These observations indicate that a minor specific change in sterol structure can exert a strong detrimental effect on a key signaling pathway of the cell, resulting in the absence of cell fusion. PMID- 27708168 TI - DNA Methylation of the hTERT Gene in Breast Cancer Revisited: Diagnostic and Clinical Implications. AB - BACKGROUND: It is documented that in tumor cell lines, the hTERT gene exhibits prominent methylation at a CpG island rich region about -600 bp upstream of the transcription start site, but mixed or allelically absent around +/-150 bp region. Given the potential clinical implications of the findings in breast cancer diagnostics, we set out to investigate if such findings are reproducible on primary surgically resected invasive breast carcinomas. METHODS: The cohort consisted of 50 cases of freshly sampled and formalin-fixed paraffin embedded (FFPE) invasive breast cancers and normal tissue. A modified quasi-quantitative methylation specific polymerase chain reaction was used to determine methylation status in cancer relative to normal tissue at the 2 CpG island-rich regions. RESULTS: A global hypermethylation is evident at the -600 bp region in both fresh and parallel FFPE breast cancers as compared to normal tissue. In contrast, most of the tumor and normal tissue remains unmethylated around the +/-150 bp region. CONCLUSIONS: Our results support further development of hTERT hypermethylation in the -600 bp region as a biomarker for breast cancer diagnostics. The unmethylated status of +/-150 bp region in normal breast tissue does not support the suggestion that unmethylation is required for hTERT gene expression. PMID- 27708169 TI - The Need for Education in Molecular Immunohematology: A Survey of Specialists in Blood Banking. AB - BACKGROUND: Within transfusion medicine, the education of molecular technologies lacks standardization. OBJECTIVE: To address this problem, we surveyed specialist in blood bank technology (SBBT) programs, immunohematology reference laboratories, and SBBT graduates to define its current state. METHODS: An anonymous online survey (SurveyMonkey) was emailed to the 15 American Association of Blood Banks (AABB) SBBT programs, 59 AABB IRLs, and 82 SBBT graduates. RESULTS: In the didactic portion of the SBBT curriculum, all programs incorporate knowledge base of blood groups, 13 incorporate molecular techniques, and 5 include case studies. Thirteen programs have intentions of expanding the knowledge base in molecular topics. Most IRLs (97%) think SBBT programs should continue to expand molecular knowledge base. Most graduates (94%) believe more molecular topics should be included in the SBBT curriculum; however, only 50% believe they currently apply their molecular knowledge in their post-graduate employment. CONCLUSION: We propose a more descriptive molecular diagnostics curriculum for SBBT programs to help standardize the education of molecular topics. PMID- 27708166 TI - Generation of an inducible colon-specific Cre enzyme mouse line for colon cancer research. AB - Current mouse models for colorectal cancer often differ significantly from human colon cancer, being largely restricted to the small intestine. Here, we aim to develop a colon-specific inducible mouse model that can faithfully recapitulate human colon cancer initiation and progression. Carbonic anhydrase I (Car1) is a gene expressed uniquely in colonic epithelial cells. We generated a colon specific inducible Car1CreER knock-in (KI) mouse with broad Cre activity in epithelial cells of the proximal colon and cecum. Deletion of the tumor suppressor gene Apc using the Car1CreER KI caused tumor formation in the cecum but did not yield adenomas in the proximal colon. Mutation of both Apc and Kras yielded microadenomas in both the cecum and the proximal colon, which progressed to macroadenomas with significant morbidity. Aggressive carcinomas with some invasion into lymph nodes developed upon combined induction of oncogenic mutations of Apc, Kras, p53, and Smad4 Importantly, no adenomas were observed in the small intestine. Additionally, we observed tumors from differentiated Car1 expressing cells with Apc/Kras mutations, suggesting that a top-down model of intestinal tumorigenesis can occur with multiple mutations. Our results establish the Car1CreER KI as a valuable mouse model to study colon-specific tumorigenesis and metastasis as well as cancer-cell-of-origin questions. PMID- 27708171 TI - Erratum. PMID- 27708170 TI - Prevalence and Clinical Utility of "Incidental" Critical Values Resulting From Critical Care Laboratory Testing. AB - OBJECTIVE: Panels of clinical laboratory testing may generate "incidental" critical values from unordered parameters. Existing regulations do not clearly delineate guidelines for handling incidental critical values. The objective of this study was to examine the patterns and clinical utility of incidental critical values at 2 critical care laboratories within an academic medical center. METHODS: In this retrospective study, the electronic health record and laboratory information system were reviewed for incidental critical results obtained from blood gas analyzer analysis of whole blood specimens between November 2010 and August 2014. RESULTS: Within the retrospective time period, 9,092 incidental critical results were documented, of which only 11.8% were added to the "parent" order following clinical notification. Incidental critical results frequently occurred in patients who had recent critical values for the same parameter. CONCLUSION: In this study, at an academic medical center, incidental critical values associated with blood gas analyzers were added on at a low rate and often provided redundant information. Relative to the manual effort involved in care providers' notification and documentation of results, incidental critical values appear to have low clinical utility.

AB - The mutable collagenous tissue (MCT) of echinoderms (e.g., sea cucumbers and starfish) is a remarkable example of a biological material that has the unique attribute, among collagenous tissues, of being able to rapidly change its stiffness and extensibility under neural control. However, the mechanisms of MCT have not been characterized at the nanoscale. Using synchrotron small-angle X-ray diffraction to probe time-dependent changes in fibrillar structure during in situ tensile testing of sea cucumber dermis, we investigate the ultrastructural mechanics of MCT by measuring fibril strain at different chemically induced mechanical states. By measuring a variable interfibrillar stiffness (EIF), the mechanism of mutability at the nanoscale can be demonstrated directly. A model of stiffness modulation via enhanced fibrillar recruitment is developed to explain the biophysical mechanisms of MCT. Understanding the mechanisms of MCT quantitatively may have applications in development of new types of mechanically tunable biomaterials. PMID- 27708172 TI - Handling Big Data in Modern Healthcare. AB - The constant growth of medical knowledge and the increases in specialization in clinical practice have created a significant need to share and access patient information with speed and efficiency. However, current technology is centered on processing data, rather than gathering information. To realize the potential of modern technology in improving patient health, merely collecting and storing data are insufficient: one must convert these data into information and knowledge. In this article, I present an overview of 2 recent advances in technology and their assimilation into the practice of medicine, in the attempt to make clinical data meaningful and then to learn from aggregated clinical data. We address the emergence of clinical data warehouses (CDWs) and health information exchanges (HIEs), as features of the Health Information Technology for Economic and Clinical Health (HITECH) Act. This act, enacted in the United States as part of the American Recovery and Reinvestment Act of 2009, was signed into law on February 17, 2009, to promote the adoption and meaningful use of health information technology.

AB - This article will help laboratories understand what changed with external quality control testing, why it changed, who changed it, when the changes became effective, and how these changes affect clinical laboratories. The new Individualized Quality Control Plan (IQCP) option that became effective January 1, 2016, will be explained. Three other quality control changes that took effect January 1, 2016, and dramatically affect quality control requirements for antimicrobial susceptibility testing, identification test systems, and exempt culture media will also be explained. Guidelines and tools are provided that can assist laboratories in determining what is eligible for IQCP and how to design an IQCP program. PMID- 27708177 TI - Neurophysiological Intraoperative Monitoring During Aortic Arch Surgery. AB - Circulatory management during replacement of the aortic arch is complex and involves a period of circulatory arrest to provide a bloodless field during arch vessel anastomosis. To guard against ischemic brain injury, tissue metabolic demand is reduced by systemically cooling the patient prior to circulatory arrest. Neurophysiological intraoperative monitoring (NIOM) is often used during the course of these procedures to provide contemporaneous assessment of brain status to help direct circulatory management decisions and detect brain ischemia. In this review, we discuss the characteristics of electrocerebral activity through the process of cooling, circulatory arrest, and rewarming as depicted through commonly used NIOM modalities, including electroencephalography and peripheral nerve somatosensory-evoked potentials. Attention is directed toward the role NIOM has traditionally played during deep hypothermic circulatory arrest, where it is used to define the point of electrocerebral inactivity or maximal cerebral metabolic suppression prior to initiating circulatory arrest while also discussing the evolving utility of NIOM when systemic circulatory arrest is initiated at more moderate degrees of hypothermia in conjunction with regional brain perfusion. The use of cerebral tissue oximetry by near-infrared spectroscopy as an alternative NIOM modality during surgery of the aortic arch is addressed as well. Finally, special considerations for NIOM and the detection of spinal cord ischemia during hybrid aortic arch repair and emerging operative techniques are also discussed. PMID- 27708178 TI - Pattern Recognition-Assisted Infrared Library Searching of the Paint Data Query Database to Enhance Lead Information from Automotive Paint Trace Evidence. AB - Multilayered automotive paint fragments, which are one of the most complex materials encountered in the forensic science laboratory, provide crucial links in criminal investigations and prosecutions. To determine the origin of these paint fragments, forensic automotive paint examiners have turned to the paint data query (PDQ) database, which allows the forensic examiner to compare the layer sequence and color, texture, and composition of the sample to paint systems of the original equipment manufacturer (OEM). However, modern automotive paints have a thin color coat and this layer on a microscopic fragment is often too thin to obtain accurate chemical and topcoat color information. A search engine has been developed for the infrared (IR) spectral libraries of the PDQ database in an effort to improve discrimination capability and permit quantification of discrimination power for OEM automotive paint comparisons. The similarity of IR spectra of the corresponding layers of various records for original finishes in the PDQ database often results in poor discrimination using commercial library search algorithms. A pattern recognition approach employing pre-filters and a cross-correlation library search algorithm that performs both a forward and backward search has been used to significantly improve the discrimination of IR spectra in the PDQ database and thus improve the accuracy of the search. This improvement permits inter-comparison of OEM automotive paint layer systems using the IR spectra alone. Such information can serve to quantify the discrimination power of the original automotive paint encountered in casework and further efforts to succinctly communicate trace evidence to the courts. PMID- 27708179 TI - Understanding and Discrimination of Biofilms of Clinically Relevant Microorganisms Using Surface-Enhanced Raman Scattering. AB - Biofilm formation is a defense mechanism for microorganisms to survive under both natural and stress conditions. Clinically relevant microorganisms threaten patient health through biofilm formation on medical devices and implants. It is very important to identify biofilm formation in order to suppress their pathogenic activities in early stages. With the aim for better understanding biofilm formation and possibility of detection, in this study, biofilm formation of clinically important microorganisms, Pseudomonas aeruginosa, Staphylococcus epidermidis, and Candida albicans are monitored with surface-enhanced Raman scattering (SERS). The SERS spectra were collected by mapping a dried droplet area where a volume of colloidal silver nanoparticle (AgNP) suspension is placed on microorganism culture plate. The spectral changes on the SERS spectra with increasing incubation time of the model microorganisms from 4 to 120 h are monitored. The unique spectra originating from the biofilms of three pathogenic microorganisms and the spectral changes as a result of time-dependent concentration fluctuations of biomolecular species in their biofilms including carbohydrates, lipids, proteins, and genetic materials allow not only identification but also discrimination of biofilms using principal component analysis. PMID- 27708180 TI - Mid-Esophagus Columnar Metaplasia: What Is the Biopathogenic Pathway? AB - We report a case of metaplastic columnar epithelium in the mid-esophagus in a patient with history of caustic ingestion. A cardiac-type gastric phenotype, with early signs of intestinalization, was confirmed by immunohistochemistry studies (MUC5AC, MUC6, SOX2, and CDX2). Nonmetaplastic mucosa had histologic evidence of gastroesophageal reflux. In this case, esophageal reepithelization seems to have been modulated by acidic gastroesophageal reflux, which might activate transcription factors leading to phenotypic reprogramming of the regenerative epithelium. Most interestingly, it is a clinical example showcasing the origin of columnar metaplasia from stem cells located within the esophageal epithelium.

AB - BACKGROUND: There are few studies of the association between the use of antioxidant vitamin supplements and the risk of Alzheimer's disease (AD). Cognitive decline is generally viewed as part of the continuum between normal aging and AD. OBJECTIVE: To evaluate whether the use of vitamin E and C supplements is associated with reduced risks of cognitive impairment, not dementia (CIND), AD, or all-cause dementia in a representative sample of older persons >=65 years old. METHODS: Data from the Canadian Study of Health and Aging (1991-2002), a cohort study of dementia including 3 evaluation waves at 5-yearly intervals, were used. Exposure to vitamins E and C was self-reported at baseline in a risk factor questionnaire and/or in a clinical examination. RESULTS: The data set included 5269 individuals. Compared with those not taking vitamin supplements, the age-, sex-, and education-adjusted hazard ratios of CIND, AD, and all-cause dementia were, respectively, 0.77 (95% CI = 0.60-0.98), 0.60 (95% CI = 0.42-0.86), and 0.62 (95% CI = 0.46-0.83) for those taking vitamin E and/or C supplements. Results remained significant in fully adjusted models except for CIND. Similar results were observed when vitamins were analyzed separately. CONCLUSIONS: This analysis suggests that the use of vitamin E and C supplements is associated with a reduced risk of cognitive decline. Further investigations are needed to determine their value as a primary prevention strategy. PMID- 27708182 TI - Microencapsulation of porcine thyroid cell organoids within a polymer microcapsule construct. AB - Hypothyroidism is a common condition of hormone deficiency, and oral administration of thyroid hormones is currently the only available treatment option. However, there are some disadvantages with this treatment modality including compliance challenges to patients. Therefore, a physiologically based alternative therapy for hypothyroidism with little or no side-effects is needed. In this study, we have developed a method for microencapsulating porcine thyroid cells as a thyroid hormone replacement approach. The hybrid wall of the polymer microcapsules permits thyroid hormone release while preventing immunoglobulin antibodies from entry. This strategy could potentially enable implantation of the microcapsule organoids containing allogeneic or xenogeneic thyroid cells to secret hormones over time without the need for immunosuppression of recipients. Porcine thyroid cells were isolated and encapsulated in alginate-poly-L-ornithine alginate microcapsules using a microfluidic device. The porcine thyroid cells formed three-dimensional follicular spheres in the microcapsules with decent cell viability and proliferation. Thyroxine release from the encapsulated cells was higher than from unencapsulated cells ( P < 0.05) and was maintained during the entire duration of experiment (>28 days). These results suggest that the microencapsulated thyroid cell organoids may have the potential to be used for therapy and/or drug screening. PMID- 27708184 TI - Elimination of Plasmodium vivax Malaria in Azerbaijan. AB - Azerbaijan in the south caucasus region of far southeastern Europe has a long history of malaria endemicity but just successfully eliminated local transmission. After a period of relatively stable malaria situation (1960-1970), the country witnessed an epidemic followed by a series of outbreaks of various magnitudes in the following two decades, all caused by Plasmodium vivax Compared with 1993, the number of malaria cases in the country jumped 29 times in 1994, 123 times in 1995, and 571 times in 1996 at the peak of the epidemic, when 13,135 cases were officially registered. Incidence rate increased dramatically from 0.2/100,000 population in 1991 to over 17/100,000 population in 1996. Scaled-up malaria control led to the containment of the epidemic and to a dramatic decrease of malaria burden nationwide. Azerbaijan has applied contemporary, complex control and surveillance strategies and approaches and is currently in the prevention of reintroduction phase. This article describes Azerbaijan's public health experience in conducting malaria control and elimination interventions over several decades until 2013 when the country reached an important milestone no indigenous malaria cases were recorded. PMID- 27708186 TI - Attacking Plasmodium vivax. AB - Discussions beginning in 2012 ultimately led to a landmark document from the World Health Organization (WHO) titled, Control and Elimination of Plasmodium vivax: A Technical Brief, published in July 2015. That body of work represents multiple expert consultations coordinated by the WHO Global Malaria Program, along with technical consensus gathering from national malaria control programs via the WHO regional offices around the globe. That document thus represents thoroughly vetted state-of-the-art recommendations for dealing specifically with P. vivax, the first assembly of such by the WHO. This supplement to the journal was commissioned by the WHO and compiles the very substantial body of evidence and analysis informing those recommendations. This introductory narrative to the supplement provides the historical and technological context of global strategy for combatting P. vivax and reducing the burdens of morbidity and mortality it imposes. PMID- 27708185 TI - Epidemiology of Plasmodium vivax in Indonesia. AB - Endemic malaria occurs across much of the vast Indonesian archipelago. All five species of Plasmodium known to naturally infect humans occur here, along with 20 species of Anopheles mosquitoes confirmed as carriers of malaria. Two species of plasmodia cause the overwhelming majority and virtually equal shares of malaria infections in Indonesia: Plasmodium falciparum and Plasmodium vivax The challenge posed by P. vivax is especially steep in Indonesia because chloroquine-resistant strains predominate, along with Chesson-like strains that relapse quickly and multiple times at short intervals in almost all patients. Indonesia's hugely diverse human population carries many variants of glucose-6-phosphate dehydrogenase (G6PD) deficiency, most of them exhibiting severely impaired enzyme activity. Therefore, the patients most likely to benefit from primaquine therapy by preventing aggressive relapse, may also be most likely to suffer harm without G6PD deficiency screening. Indonesia faces the challenge of controlling and eventually eliminating malaria across > 13,500 islands stretching > 5,000 km and an enormous diversity of ecological, ethnographic, and socioeconomic settings, and extensive human migrations. This article describes the occurrence of P. vivax in Indonesia and the obstacles faced in eliminating its transmission. PMID- 27708187 TI - Plasmodium vivax Malaria in Cambodia. AB - The Cambodian National Strategic Plan for Elimination of Malaria aims to move step by step toward elimination of malaria across Cambodia with an initial focus on Plasmodium falciparum malaria before achieving elimination of all forms of malaria, including Plasmodium vivax in 2025. The emergence of artemisinin resistant P. falciparum in western Cambodia over the last decade has drawn global attention to support the ultimate goal of P. falciparum elimination, whereas the control of P. vivax lags much behind, making the 2025 target gradually less achievable unless greater attention is given to P. vivax elimination in the country. The following review presents in detail the past and current situation regarding P. vivax malaria, activities of the National Malaria Control Program, and interventional measures applied. Constraints and obstacles that can jeopardize our efforts to eliminate this parasite species are discussed. PMID- 27708188 TI - Epidemiology of Plasmodium vivax Malaria in India. AB - Historically, malaria in India was predominantly caused by Plasmodium vivax, accounting for 53% of the estimated cases. After the spread of drug-resistant Plasmodium falciparum in the 1990s, the prevalence of the two species remained equivalent at the national level for a decade. By 2014, the proportion of P. vivax has decreased to 34% nationally, but with high regional variation. In 2014, P. vivax accounted for around 380,000 malaria cases in India; almost a sixth of all P. vivax cases reported globally. Plasmodium vivax has remained resistant to control measures, particularly in urban areas. Urban malaria is predominantly caused by P. vivax and is subject to outbreaks, often associated with increased mortality, and triggered by bursts of migration and construction. The epidemiology of P. vivax varies substantially within India, including multiple relapse phenotypes with varying latencies between primary infection and relapse. Moreover, the hypnozoite reservoir maintains transmission potential and enables reestablishment of the parasite in areas in which it was thought eradicated. The burden of malaria in India is complex because of the highly variable malaria eco epidemiological profiles, transmission factors, and the presence of multiple Plasmodium species and Anopheles vectors. This review of P. vivax malaria in India describes epidemiological trends with particular attention to four states: Gujarat, Karnataka, Haryana, and Odisha. PMID- 27708189 TI - Epidemiology and Control of Plasmodium vivax in Afghanistan. AB - Around half of the population of Afghanistan resides in areas at risk of malaria transmission. Two species of malaria (Plasmodium vivax and Plasmodium falciparum) account for a high burden of disease-in 2011, there were more than 300,000 confirmed cases. Around 80-95% of malaria is P. vivax Transmission is seasonal and focal, below 2,000 m in altitude, and in irrigated areas which allow breeding of anopheline mosquito vectors. Malaria risk is stratified to improve targeting of interventions. Sixty-three of 400 districts account for ~85% of cases, and are the target of more intense control efforts. Pressure on the disease is maintained through case management, surveillance, and use of long-lasting insecticide treated nets. Plasmodium vivax treatment is hampered by the inability to safely treat latent hypnozoites with primaquine because G6PD deficiency affects up to 10% of males in some ethnic groups. The risk of vivax malaria recurrence (which may be as a result of reinfection or relapse) is around 30-45% in groups not treated with primaquine but 3-20% in those given 14-day or 8-week courses of primaquine. Greater access to G6PD testing and radical treatment would reduce the number of incident cases, reduce the infectious reservoir in the population, and has the potential to reduce transmission as a result. Alongside the lack of G6PD testing, under-resourcing and poor security hamper the control of malaria. Recent gains in reducing the burden of disease are fragile and at risk of reversal if pressure on the disease is not maintained. PMID- 27708192 TI - Romidepsin-associated cardiac toxicity and ECG changes: A case report and review of the literature. AB - Background Romidepsin is a novel histone deacetylase inhibitor that is approved for the treatment of cutaneous and peripheral T-cell lymphoma in patients who have had at least one prior therapy. Romidepsin is generally well tolerated, though it comes with a risk of cardiac toxicities. Objective We report a case of electrocardiogram changes in a 64-year-old male with enteropathy-associated T cell lymphoma, type 2, treated with salvage romidepsin therapy who relapsed after non-myeloablative allogeneic sibling peripheral blood stem cell transplant. Discussion Although histone deacetylase inhibitors have been investigated for many years, they have only recently been translated to clinical use as a therapy for malignancies. Furthermore, given their approval for a rare disease, clinicians often have limited experience with the dosing and side effects of histone deacetylase inhibitors. Conclusion This case report and literature review investigates the cardiac side effects of histone deacetylase inhibitors and illustrates the importance of cardiac monitoring prior to and during treatment. PMID- 27708190 TI - Plasmodium vivax Landscape in Brazil: Scenario and Challenges. AB - Brazil is the largest country of Latin America, with a considerable portion of its territoritory within the malaria-endemic Amazon region in the North. Furthermore, a considerable portion of its territory is located within the Amazon region in the north. As a result, Brazil has reported half of the total malaria cases in the Americas in the last four decades. Recent progress in malaria control has been accompanied by an increasing proportion of Plasmodium vivax, underscoring a need for a better understanding of management and control of this species and associated challenges. Among these challenges, the contribution of vivax malaria relapses, earlier production of gametocytes (compared with Plasmodium falciparum), inexistent methods to diagnose hypnozoite carriers, and decreasing efficacy of available antimalarials need to be addressed. Innovative tools, strategies, and technologies are needed to achieve further progress toward sustainable malaria elimination. Further difficulties also arise from dealing with the inherent socioeconomic and environmental particularities of the Amazon region and its dynamic changes. PMID- 27708194 TI - Effects of the Janus Kinase Inhibitor, Tofacitinib, on Testicular Leydig Cell Hyperplasia and Adenoma in Rats, and on Prolactin Signaling in Cultured Primary Rat Leydig Cells. AB - Tofacitinib is an oral Janus kinase (JAK) inhibitor for the treatment of rheumatoid arthritis. Tofacitinib preferentially inhibits receptor signaling through JAK3 and JAK1, relative to JAK2. In the 2-year rat carcinogenicity study, there were tofacitinib, dose-related increases in the incidences of testicular Leydig cell hyperplasia and benign adenomas in male rats, and decreased incidences of mammary tumors and duct dilatation/galactocele in female rats. Such findings in rats are typical of agents, such as dopamine agonists, which decrease prolactin (PRL) activity. Since prolactin signals through the JAK2 pathway, we hypothesized that these findings were off-target effects due to inhibition of PRL signaling via JAK2. The studies reported here were designed to investigate the interruption of PRL signaling pathways in Leydig cells. In isolated primary rat Leydig cells, PRL increased phosphorylated Signal Transducer and Activator of Transcription-5 protein, and mRNA levels for luteinizing hormone receptor. Tofacitinib, at concentrations observed in the rat carcinogenicity study, dose dependently inhibited these effects. These observations illustrate a novel mechanism, the inhibition of prolactin signaling by which modulation of JAK activity can modulate PRL signaling pathways to induce Leydig cell tumors in rats. Since human Leydig cells lack this PRL dependence for normal function, these rodent tumors do not indicate a health risk to human patients. PMID- 27708193 TI - Editor's Highlight: Role of Spleen-Derived Macrophages in Ozone-Induced Lung Inflammation and Injury. AB - Macrophages and inflammatory mediators have been implicated in ozone toxicity. In these studies, we used splenectomized (SPX) mice to assess the contribution of splenic monocytes to pulmonary inflammation and injury induced by ozone. Cells and tissue were collected 24-72 h after exposure of mice to air or ozone (0.8 ppm, 3 h). Following ozone exposure, increased numbers of pro-inflammatory CD11b + Ly6CHi and anti-inflammatory CD11b + Ly6CLo monocytes were observed in spleens of control (CTL) mice. CD11b + Ly6CHi and MMP-9+ pro-inflammatory macrophages were also observed in lungs of CTL mice after ozone, along with CD11b + Ly6CLo and mannose receptor (MR)+ anti-inflammatory macrophages. This was accompanied by increased lung expression of proteins involved in monocyte/macrophage trafficking including CCL3, CCL4, CCR1, and AT1R. Splenectomy resulted in decreases in pro inflammatory macrophages in the lung and down regulation of CCR2, CCL2, and CCL4, but increases in CD11b + Ly6CLo anti-inflammatory macrophages. CD11b+Ly6G+Ly6C+ granulocytic (G)- and monocytic (M)-myeloid derived suppressor cells (MDSC)s were also detected in the lungs and spleens of CTL mice; these increased after ozone exposure. Splenectomy was associated with a decrease in G-MDSCs in the lung, with no effect on M-MDSCs. Changes in lung macrophage subpopulations and MDSCs in SPX mice were correlated with reduced ozone toxicity, as measured by decreases in bronchoalveolar lavage protein content and reduced 4-hydroxynonenal expression in the lung. These data suggest that the spleen is a source of pro inflammatory/cytotoxic macrophages that contribute to ozone-induced lung injury, inflammation, and oxidative stress. PMID- 27708191 TI - Diagnosis and Treatment of Plasmodium vivax Malaria. AB - The diagnosis and treatment of Plasmodium vivax malaria differs from that of Plasmodium falciparum malaria in fundamentally important ways. This article reviews the guiding principles, practices, and evidence underpinning the diagnosis and treatment of P. vivax malaria. PMID- 27708195 TI - Risk Factors Associated With Inpatient Violence During Medium Security Treatment. AB - Violence is a common phenomenon both in regular and forensic psychiatric settings, and has a profound impact on staff and other patients. Insight into the individual risk factors associated with violence in forensic psychiatric settings is rare and is therefore the subject of this research. A retrospective file study in three medium security units in Flanders was conducted to compare non-violent inpatients with inpatients who engaged in (verbal and physical) violent behavior. Binary logistic regression analyses were used to examine which variables contributed independently to the risk of violence. The results showed that absconding during treatment was independently associated with physical violence. A personality disorder diagnosis and general non-compliance with treatment were associated with verbal violence. Both types of violence predicted early termination of treatment. Contrary to previous research, the results from the risk assessment tools were not associated with inpatient violence. Clinical implications are discussed and include, among others, that clinicians should remain vigilant for early warning signs of non-compliance during treatment. PMID- 27708196 TI - Who Gets Protection? A National Study of Multiple Victimization and Child Protection Among Taiwanese Children. AB - This study aims to examine the prevalence of multiple types of child victimization and the effects of multiple types of victimization on children's mental health and behavior in Taiwan. The study also examines the child protection rate and its correlates among children experiencing various types of victimization. This study collected data with a self-report questionnaire from a national proportionately stratified sample of 6,233 fourth-grade students covering every city and county in Taiwan in 2014. After calculating the 1-year prevalence of child victimization, the study found that bullying was the most prevalent (71%), followed by physical neglect (66%), psychological violence (43%), inter-parental violence (28%), community violence (22%), physical abuse (21%), and sexual violence (9%). As the number of victimization types increased, children were more likely to report greater posttraumatic symptoms, psychiatric symptoms, suicide ideation, self-harm thoughts, and violent behaviors. Gender, neonatal status, parental marital status, and other family risks were significantly associated with elevated incidences of the victimization types. Only 20.6% of the children who had experienced all seven types of victimization had received child protective services. A child was more likely to receive child protective services if he or she had experienced sexual violence, community violence, inter-parental violence exposure, higher family risks, higher suicidal ideation, or living in a single-parent or separated family. In conclusion, this study demonstrates the cumulative effects and the harmful effects that children's experience of multiple types of victimization can have on the children's mental health and behavior. The present findings also raise alarms regarding the severity of under-serving in child-victimization cases. These results underscore the importance of assessing, identifying, and helping children with multiple victimization experiences. PMID- 27708197 TI - Influence of Study Design on Developmental and Reproductive Toxicology Study Outcomes. AB - Regulatory studies of developmental and reproductive toxicity (DART) studies have remained largely unchanged for decades, with exposures occurring at various phases of the reproductive cycle and toxicity evaluations at different ages/times depending on the study purpose. The National Toxicology Program has conducted studies examining the power to detect adverse effects where there is a prenatal exposure, but evaluations occur postnatally. In these studies, examination is required of only 1 male and female pup from each litter beyond weaning. This provides poor resolving power to detect rare events (e.g., reproductive tract malformations). If an adverse effect is detected, there is little confidence in the shape of the dose-response curve (and the Benchmark Dose or No Observed Adverse Effect Level [NOAEL]). We have developed a new protocol to evaluate DART, the modified one generation study, with exposure commencing with pregnant animals and retention of 4 males and females from each litter beyond weaning to improve statistical power. These animals can be allocated to specific cohorts that examine subchronic toxicity, teratology, littering, and neurobehavioral toxicity in the same study. This approach also results in a reduction in animal numbers used, compared with individual stand-alone studies, and offers increased numbers of end points evaluated compared with recent Organization for Economic Cooperation and Development proposals. PMID- 27708198 TI - A Synopsis of the "Influence of Epigenetics, Genetics, and Immunology" Session Part A at the 35th Annual Society of Toxicologic Pathology Symposium. AB - The overarching theme of the 2016 Society of Toxicology Pathology's Annual Symposium was "The Basis and Relevance of Variation in Toxicologic Responses." Session 4 focused on genetic variation as a potential source for variability in toxicologic responses within nonclinical toxicity studies and further explored how knowledge of genetic traits might enable targeted prospective and retrospective studies in drug development and human health risk assessment. In this session, the influence of both genetic sequence variation and epigenetic modifications on toxicologic responses and their implications for understanding risk were explored. In this overview, the presentations in this session will be summarized, with a goal of exploring the ramifications of genetic and epigenetic variability within and across species for toxicity studies and disseminating information regarding novel tools to harness this variability to advance understanding of toxicologic responses across populations.

PMID- 27708204 TI - Evidence for the efficacy of immunotherapy in children with high-risk neuroblastoma. AB - Neuroblastoma is the most common extra-cranial malignancy of childhood, with the highest incidence in children younger than 4 years. The prognosis depends on many factors, such as age at diagnosis, stage of disease and molecular genetic subtype. More than 50% of children who present with the disease are deemed to have high-risk neuroblastoma. The standard therapy for children with high-risk neuroblastoma consists of intensive chemotherapy, surgery, radiotherapy, myeloablative consolidation with autologous haematopoietic stem cell rescue followed by the treatment of minimal residual disease with 13-cis-retinoic acid. Unfortunately, more than half of the patients relapse regardless of the treatment intensity. Combined therapy with monoclonal antibodies (anti-GD2), intravenous interleukin-2 (Il-2), intravenous granulocyte-macrophage colony-stimulating factor (GM-CSF) and oral 13-cis-retinoic acid have been proved to be effective in some randomised trials. A better understanding of the underlying immunological processes in therapy with anti-GD2 antibodies will allow its success to be evaluated more accurately and direct future endeavours. Nevertheless, the long term benefit of this treatment approach needs to be established. PMID- 27708205 TI - The classification, structure and functioning of Ago proteins in Eukaryotes. AB - Ago proteins are members of the highly specialized and conserved Argonaute family, primarily responsible for regulation of gene expression. As a part of RNA induced silencing complexes (RISCs) Ago proteins are responsible for binding a short RNA and cleavage/inhibition of translation of target mRNAs. Phosphorylation may work as the switch between those two functions, but the role of magnesium ion concentration is also taken into consideration. Recent reports indicate that Ago proteins can interact with an mRNA and cause inhibition of translation without the participation of a short RNA. As key elements in RNA interference processes, Ago proteins are an important and intensively exploited area of research. Furthermore, these proteins are involved in the repair of DNA double-strand breaks by homologous recombination, modifications of chromatin, and alternative splicing. Their role in the cell cycle and senescence is also being studied. In addition, Ago expression is tissue-specific, which potentially may be used for diagnostic purposes. Understanding the mechanisms of Ago functioning is therefore crucial for understanding many cellular processes. The following article presents a detailed description of the Ago proteins including their post-translational modifications, recent data and hypotheses concerning their interactions with short RNAs and mRNAs as well as the mechanisms of siRNA/miRNA sorting into individual members of the Ago subfamily, and their role in eukaryotic cells. The latest classification of Ago proteins within the Argonaute family based on evolutionary studies and their possible interactions with DNA are also described. PMID- 27708206 TI - Short-term exposure to ambient fine particulate matter (PM2,5 and PM10) and the risk of heart rhythm abnormalities and stroke. AB - Results of epidemiological studies suggest a significant impact of ambient particulate matter air pollution (PM10 and PM2,5) on the health of the population. Increased level of these pollutants is connected with increased rate of daily mortality and hospitalizations due to cardiovascular diseases. Among analyzed health effects, heart arrhythmias and stroke are mentioned most frequently. The aim of the study was to present the current knowledge of potential influence of the exposure to fine particulate matter on the presence of arrhythmias and strokes. Subject literature review suggests, that there is a link between short-term exposure to fine dust and the occurrence of arrhythmias. Results of previous studies indicates that this exposure may lead to significant electrophysiological changes in heart, resulting in higher susceptibility to cardiac rhythm abnormalities. In case of stroke, a stronger correlation between number of hospitalizations and death cases and exposure to fine dust was seen for ischaemic stroke than for haemorhhagic stroke. In addition, a significantly more harmful impact of the exposure to ultra particles (particles of aerodynamic diameter below 2,5 MUm) has been confirmed. Among important mechanisms responsible for observed health impact of particulate matter there are: induction and intensification of inflammation, increased oxidative stress, increased autonomic nervous system activity, vasoconstriction, rheological changes and endothelial dysfunction. Among people of higher susceptibility to fine dust negative health impact are: elderly (over 65 years old), obese people, patients with respiratory and cardiovascular diseases, patients with diabetes and those with coagulation disorders. For further improvement of general health status, actions aimed at reducing the risk associated with fine dust and at the same time at continuing studies to clarify the biological mechanisms explaining the influence of fine dust on human health are necessary. PMID- 27708207 TI - Role of oncogene 24p3 neutrophil gelatinase-associated lipocalin (NGAL) in digestive system cancers. AB - Neutrophil gelatinase-associated lipocalin, known also as 24p3 lipocalin, lipocalin-2 or uterocalin (in mouse), is a small secretory protein binding small molecular weight ligands which takes part in numerous processes including apoptosis induction in leukocytes, iron transport, smell, and prostaglandins and retinol transport [19]. It was discovered in activated neutrophils as a covalent peptide associated with human gelatinase neutrophils [7]. Neutrophil lipocalin is secreted physiologically in the digestive system, respiratory tract, renal tubular cells, liver or immunity system. Systematic (circulated in plasma) neutrophil gelatinase come from multiple sources; it may be synthesized in the liver, secreted from activated neutrophils or macrophages, or derive from atherosclerosis or inflammatory endothelial cells [17]. NGAL is stored secondarily in granulates with lactoferrin, calprotectin or MAC-1, which take part in neutrophils' action and migration [13,19]. NGAL participates in acute and chronic inflammation (production of NGAL is indicated by factors conducive to cancer progression) [13,21]. NGAL levels increase in inflammatory or endothelial damage. NGAL level is measured in blood or urine. It is known as a kidney failure factor [7,20]. NGAL is therefore one of the most promising new generation biomarkers in clinical nephrology [6]. The role of NGAL in digestive system neoplasms has not been explored in detail. However, overexpression of this marker was proved in neoplasms such as esophageal carcinoma, stomach cancer, pancreatic cancer or colon cancer, which may indicate an association between concentration and neoplasm [3]. PMID- 27708208 TI - Vaccines in prophylaxis of urinary tract infections caused by the bacteria from the genus Proteus. AB - Urinary tract infections (UTIs) pose a threat especially to women, the individuals with weakened immunity or with abnormalities in the urinary tract as well as to hospitalized and catheterized patients. The bacteria from the genus Proteus, especially P. mirabilis, are important UTI pathogenic factors. They frequently cause chronic, recurrent or severely complicated infections, resulting in the urinary stones production due to urease and other virulence factors. The ability to survive inside the stones and the increasing antibiotic resistance make it difficult to eradicate the bacteria from the urinary tract. A good solution to the problem may be the vaccination which obtained the interest from the surveyed persons, in spite of the antivaccination attitudes visible also in Poland. Currently, there are four vaccines available, composed of killed cells of different uropathogens, including Proteus spp. They are administrated intranassaly or vaginally and require many booster doses. They decrease the probability of reinfection in patients suffering from recurrent UTIs but the mechanisms of the immune response have not been exactly defined. Promising results were obtained in the studies on a mice model concerning the subunit, conjugated vaccines in which various P. mirabilis surface antigens (with the exception of flagellin) were successfully employed. Hitherto, the best results were obtained by the intranasal vaccinations, using MR/P fimbriae antigens with MPL or cholera toxin adjuvants and the antigens expressed in Lactococcus lactis or Salmonella Typhimurium. It led to an increase in the levels of the specific serum and mucosal antibodies resulting in the protection against P. mirabilis UTIs. PMID- 27708209 TI - PD1/PD1L pathway, HLA-G and T regulatory cells as new markers of immunosuppression in cancers. AB - The appropriate function of the immune system depends on the effective regulation of the immune response on multiple levels. The key element of an effective immune response to antigenic stimulation is maintaining a homeostasis between activation and inhibitory function of immunocompetent cells and molecules. In pathological conditions such as chronic infections, autoimmune diseases or cancer there are significant alterations, and prevalence of signals of one type over another. Main markers of these dysfunctions are altered expressions of molecules, such as programmed death-1 (PD-1), Human Leukocyte Antigen G (HLA-G), or changed percentages of T regulatory cells (Treg). These indicators of immune system dysfunction may contribute to disease progression, but also could represent good targets for treatment. Interestingly, in recent years there are many new, interesting reports which showed that the role of PD-1, HLA-G or Treg is ambiguous and not always their higher expression or frequency lead to the progression of disease. Recent studies have shown that Treg can suppress bacteria driven inflammation which promotes carcinogenesis and thus protect the host from cancer development. Moreover, proliferation of hematological tumor cells expressing ILT-2 receptor can be inhibited by HLA-G, in contrast to solid tumors where HLA-G favors tumor escape. In this paper we present characteristics of expressions of PD-1 and its ligands, HLA-G, and frequency of Treg cells in a variety of physiological and pathological conditions associated with chronic infections, autoimmune diseases and cancer. The understanding of the complex interactions between the functional elements of immune system is essential for a detailed characteristics of the mechanisms leading to the development of diseases and identification of more effective targeted therapies. PMID- 27708210 TI - Immunoregulatory action of melatonin. The mechanism of action and the effect on inflammatory cells. AB - Literature data indicate a significant immunoregulatory role of melatonin. Melatonin exerts an effect directly affecting leucocytes bearing specific melatonin receptors or indirectly by means of melatonin regulating other hormones, opioids or cytokines. Despite numerous experiments, the influence of the hormone on the immune system is still controversial. Melatonin affects the immune response acting as both an activator and an inhibitor of the inflammatory process. The hormone acts as an "immunological buffer" activating impaired immunity in immunosuppression, chronic stress or old age as well as suppressing overreaction of the immune system. Melatonin mediates between neurohormonal and immune systems by means of the immune-pineal axis acting as a negative feedback mechanism. The axis connects development of the immune reaction with pineal activity and melatonin secretion induced by inflammatory mediators. The seasonal and circadian fluctuation of the melatonin level and the fluctuation related changes of the immune parameters can be responsible for some autoimmune and infectious diseases. In spite of that, there is a growing number of papers suggesting considerable therapeutic potential of melatonin in inflammatory disease treatment. This paper presents well-systematized information on the mechanism of melatonin action and its influence on cells involved in the inflammatory process - neutrophils and monocytes. PMID- 27708211 TI - Can mutations in the gene encoding transcription factor EKLF (Erythroid Kruppel Like Factor) protect us against infectious and parasitic diseases? AB - Transcription factor EKLF (Erythroid Kruppel-Like Factor) belongs to the group of Kruppellike factors, which regulate proliferation, differentiation, development and apoptosis of mammalian cells. EKLF factor is present in erythroid cells, where it participates in regulation of hematopoiesis, expression of genes encoding transmembrane proteins (including blood group antigens), and heme biosynthesis enzymes. It is also a key factor in downregulation of gamma-globins and activation of beta-globin gene expression. The EKLF factor consists of two domains: proline-rich transactivation domain and DNA-binding domain containing three zinc finger motifs, which recognize DNA. EKLF can act as a transcription activator (for example in the case of beta-globin gene) or repressor, which depends on the type of posttranslational modification (phosphorylation, SUMOylation, ubiquitination and acetylation). Mutations in the gene encoding EKLF may cause hemoglobinopathies, such as hereditary persistence of fetal hemoglobin and beta-thalassemia intermedia, and congenital dyserythropoietic anemia type IV, which is a hematopoietic disorder. These changes may impede invasion of red blood cells by malaria merozoites and cause faster removal of invaded erythrocytes. In addition, mutations in KLF1 may decrease the number of erythrocyte surface antigens that belong to blood group systems such as MN, P1PK, Lutheran, Duffy, Diego and OK. Such antigens can be receptors for protozoans (such as Plasmodium falciparum or Plasmodium vivax), bacteria (like uropathogenic strains of Escherichia coli, Neisseria meningitidis), and toxins (Shiga toxins), which may cause several dangerous diseases including malaria, pyelonephritis, hemorrhagic colitis, hemolytic uremic syndrome (HUS) and meningitis. Here, we propose a hypothesis on possible liaisons between mutations in the gene encoding EKLF and resistance to pathogens. PMID- 27708212 TI - Paxillin and its role in the aging process of skin cells. AB - Morphology of senescent cells is constantly changing at the molecular level, which in turn leads to disruption of their function. It is connected with reduced ability to synthesize extracellular matrix (ECM) and leads to the dysfunction of integrin adhesion molecules and adhesion clusters. In skin, these factors cause a loss of communication between the extracellular matrix and fibroblasts. This contributes to the appearance of signs of aging. The aim of this study is to draw attention to the very important molecule such as paxillin, which is an adaptor protein with mass of 68 kDa. This family of proteins includes Hic-5, PaxB and leupaxin. Paxillin binds to actin-binding proteins such as vinculin, actopaxin, and kinases (e.g. Integrin-linked kinase (ILK)). Moreover, it plays an important role in the integrity of the matrix, because it transduces transmembrane signaling between integrins and growth factors. Paxillin is a scaffold protein, activating the arrangement and organization of the cytoskeleton. Signaling through paxillin affects the long-term changes in gene expression, cell proliferation, and organization of the ECM. Correct functioning of the ECM is important for the wound healing processes and regeneration of tissues or tissue repair. Decrease or lack of paxillin expression results in changes in the structure and integrity of the ECM, which are manifested by aging of cells and organs. Restoration of the cellular matrix connections would be a significant element in the processes related to the anti-aging activities. PMID- 27708213 TI - Resistance to PARP inhibitors by SLFN11 inactivation can be overcome by ATR inhibition. AB - Poly(ADP-ribose) polymerase inhibitors (PARPIs) kill cancer cells by trapping PARP1 and PARP2. Talazoparib, the most potent PARPI inhibitor (PARPI), exhibits remarkable selectivity among the NCI-60 cancer cell lines beyond BRCA inactivation. Our genomic analyses reveal high correlation between response to talazoparib and Schlafen 11 (SLFN11) expression. Causality was established in four isogenic SLFN11-positive and -negative cell lines and extended to olaparib. Response to the talazoparib-temozolomide combination was also driven by SLFN11 and validated in 36 small cell lung cancer cell lines, and in xenograft models. Resistance in SLFN11-deficient cells was caused neither by impaired drug penetration nor by activation of homologous recombination. Rather, SLFN11 induced irreversible and lethal replication inhibition, which was independent of ATR mediated S-phase checkpoint. The resistance to PARPIs by SLFN11 inactivation was overcome by ATR inhibition, mechanistically because SLFN11-deficient cells solely rely on ATR activation for their survival under PARPI treatment. Our study reveals that SLFN11 inactivation, which is common (~45%) in cancer cells, is a novel and dominant resistance determinant to PARPIs. PMID- 27708214 TI - Novel nomograms for survival and progression in HPV+ and HPV- oropharyngeal cancer: a population-based study of 1,542 consecutive patients. AB - BACKGROUND: No study has combined tumour and clinical covariates for survival to construct an individual risk-profile for overall survival (OS), time to progression (TTP), and survival after progression (SAP) in patients with HPV+ and HPV- oropharyngeal squamous cell carcinoma (OPSCC). Based on the largest-to-date, unselected, population-based cohort of patients diagnosed with OPSCC, we performed a comprehensive analysis of long-term OS, TTP, and SAP and constructed novel nomograms to evaluate patients' prognoses. RESULTS: At a median follow-up of 4.0 years (range: 0.8-15.8 yrs.), 690 deaths were recorded. The 5-year OS, TTP, and SAP for the HPV+/p16+ subgroup were 77%, 82%, and 33, vs. 30%, 66%, and 6% for the HPV-/p16- group (P < 0.01). 376 patients failed to maintain disease control with a median TTP of 13 months in the HPV+/p16+ subgroup vs. 8.5 months in the HPV-/p16- subgroup (P < 0.05). HPV combined with p16 status remained one of the most informative covariates in the final Cox regression model for OS, TTP, and SAP. METHODS: We included all patients diagnosed with OPSCC (n = 1,542) between 2000-2014 in Eastern Denmark. Survival rates were estimated by the Kaplan Meier method. A multivariate Cox regression model was used to construct predictive, internally validated nomograms. CONCLUSION: The HPV+/p16+ subgroup had improved OS, TTP, and SAP compared with other combinations of HPV and p16 after adjusting for covariates. Nomograms were constructed for 1-, 5- and 10-year survival probability. Models may aid patients and clinicians in their clinical decision making as well as in counselling, research, and trial design. PMID- 27708215 TI - DACT2 silencing by promoter CpG methylation disrupts its regulation of epithelial to-mesenchymal transition and cytoskeleton reorganization in breast cancer cells. AB - Wnt signaling plays an important role in breast carcinogenesis. DAPPER2 (DACT2) functions as an inhibitor of canonical Wnt signaling and plays distinct roles in different cell contexts, with its role in breast tumorigenesis unclear. We investigated DACT2 expression in breast cancer cell lines and primary tumors, as well as its functions and molecular mechanisms. Results showed that DACT2 expression was silenced in 9/9 of cell lines. Promoter CpG methylation of DACT2 was detected in 89% (8/9) of cell lines, as well as in 73% (107/147) of primary tumors, but only in 20% (1/5) of surgical margin tissues and in none of normal breast tissues. Demethylation of BT549 and T47D cell lines with 5-aza-2' deoxycytidine restored DACT2 expression along with promoter demethylation, suggesting that its downregulation in breast cancer is dependent on promoter methylation. Furthermore, ectopic expression of DACT2 induced breast cell apoptosis in vitro, and further inhibited breast tumor cell proliferation, migration and EMT, through antagonizing Wnt/beta-catenin and Akt/GSK-3 signaling. Thus, these results demonstrate that DACT2 functions as a tumor suppressor for breast cancer but was frequently disrupted epigenetically in this cancer. PMID- 27708217 TI - The role of surgical intervention in primary colorectal lymphoma: A SEER population-based analysis. AB - BACKGROUND: Primary colorectal lymphoma (PCL) is a rare colorectal malignancy. The standard treatment and prognostic factors of PCL remain unexplored. Therefore, a large population-based study should be conducted to provide a detailed review of this disease. METHODS: We extracted the data of eligible patients with PCL registered in the SEER database from 1973 to 2011. All statistical analyses were performed using SPSS 19.0. RESULTS: A total of 2050 (61.3%) of the 3342 patients with PCL underwent surgical intervention, and 1292 (38.7%) patients received no surgical treatment. The median overall survival was 95 months, and patients receiving surgery exhibited significantly prolonged survival (adjusted HR =0.69, P <0.001). Young age, early tumor stage, and indolent lymphoma were independent predictors of improved survival. Further survival analyses demonstrated the potential benefit of surgery in patients with early tumor stage, right-sided lesions, or diffuse large B-cell PCL. Conversely, surgical intervention did not improve the survival of patients with advanced stage, left-sided, or indolent PCL. CONCLUSION: PCL is a rare tumor that can be effectively treated. Surgical intervention may play an important role in the treatment of PCL. Early tumor stage, a right-sided lesion, and diffuse large B cell histological PCL seem to be the clinical characteristics of optimal surgical candidates. PMID- 27708216 TI - Smoking-associated lung cancer prevention by blockade of the beta-adrenergic receptor-mediated insulin-like growth factor receptor activation. AB - Activation of receptor tyrosine kinases (RTKs) is associated with carcinogenesis, but its contribution to smoking-associated lung carcinogenesis is poorly understood. Here we show that a tobacco-specific carcinogen 4-(methylnitrosamino) 1-(3-pyridyl)-1-butanone (NNK)-induced insulin-like growth factor 1 receptor (IGF 1R) activation via beta-adrenergic receptor (beta-AR) is crucial for smoking associated lung carcinogenesis. Treatment with NNK stimulated the IGF-1R signaling pathway in a time- and dose-dependent manner, which was suppressed by pharmacological or genomic blockade of beta-AR and the downstream signaling including a Gbetagamma subunit of beta-AR and phospholipase C (PLC). Consistently, beta-AR agonists led to increased IGF-1R phosphorylation. The increase in IGF2 transcription via beta-AR, signal transducer and activator of transcription 3 (STAT3), and nuclear factor-kappa B (NF-kappaB) was associated with NNK-induced IGF-1R activation. Finally, treatment with beta-AR antagonists suppressed the acquisition of transformed phenotypes in lung epithelial cells and lung tumor formation in mice. These results suggest that blocking beta-AR mediated IGF-1R activation can be an effective strategy for lung cancer prevention in smokers. PMID- 27708218 TI - Overexpression of caveolin-1 attenuates brain edema by inhibiting tight junction degradation. AB - Cerebral edema from the disruption of the blood-brain barrier (BBB) after cerebral ischemia is a major cause of morbidity and mortality as well as a common event in patients with stroke. Caveolins (Cavs) are thought to regulate BBB functions. Here, we report for the first time that Cav-1 overexpression (OE) decreased brain edema from BBB disruption following ischemic insult. Edema volumes and Cav-1 expression levels were measured following photothrombosis and middle cerebral artery occlusion (MCAO). Endothelial cells that were transduced with a Cav-1 lentiviral expression vector were transplanted into rats. BBB permeability was quantified with Evans blue extravasation. Edema volume was determined from measures of the extravasation area, brain water content, and average fluorescence intensity after Cy5.5 injections. Tight junction (TJ) protein expression was measured with immunoblotting. Cav-1 expression levels and vasogenic brain edema correlated strongly after ischemic insult. Cav-1 expression and BBB disruption peaked 3 d after the MCAO. In addition, intravenous administration of endothelial cells expressing Cav-1 effectively increased the Cav-1 levels 3 d after the MCAO ischemic insult. Importantly, Cav-1 OE ameliorated the vasogenic edema by inhibiting the degradation of TJ protein expression in the acute phase of ischemic stroke. These results suggested that Cav-1 OE protected the integrity of the BBB mainly by preventing the degradation of TJ proteins in rats. These findings need to be confirmed in a clinical setting in human subjects. PMID- 27708219 TI - A small deletion in SERPINC1 causes type I antithrombin deficiency by promoting endoplasmic reticulum stress. AB - Antithrombin (AT) deficiency is an autosomal dominant disorder, and identification of mutation AT variants would improve our understanding of the anticoagulant function of this serine protease inhibitor (SERPIN) and the molecular pathways underlying this disorder. In the present study, we performed whole-exome sequencing of a Chinese family with deep vein thrombosis, and identified a new small deletion that eliminates four amino acids (INEL) from exon 4 of SERPINC1 gene. This causes type I AT deficiency by enhancing the intracellular retention of this protein. AT retention leads to endoplasmic reticulum (ER) stress, which further inhibits AT release. In addition, ER stress activates ER-associated degradation, which promotes AT degradation. Suppression of ER stress enhanced the secretion of AT, while inhibition of ER-associated degradation suppressed AT release. Thus, our study identified a new mutation (INEL deletion) causing type I AT deficiency, and uncovered a novel mechanism for AT retention through enhanced ER stress, which may provide an innovative approach for treating AT deficiency. PMID- 27708220 TI - Myocardin-related transcription factor A (MRTF-A) activity-dependent cell adhesion is correlated to focal adhesion kinase (FAK) activity. AB - The regulation of cell-substrate adhesion is tightly linked to the malignant phenotype of tumor cells and plays a role in their migration, invasion, and metastasis. Focal adhesions (FAs) are dynamic adhesion structures that anchor the cell to the extracellular matrix. Myocardin-related transcription factors (MRTFs), co-regulators of the serum response factor (SRF), regulate expression of a set of genes encoding actin cytoskeletal/FA-related proteins. Here we demonstrated that the forced expression of a constitutively active MRTF-A (CA MRTF-A) in B16F10 melanoma cells induced the up-regulation of actin cytoskeletal and FA proteins, resulting in FA reorganization and the suppression of cell migration. Expression of CA-MRTF-A markedly increased phosphorylation of focal adhesion kinase (FAK) and paxillin, which are important components for FA dynamics. Notably, FAK activation was triggered by the clustering of up-regulated integrins. Our results revealed that the MRTF-SRF-dependent regulation of cell migration requires both the up-regulation of actin cytoskeletal/FA proteins and the integrin-mediated regulation of FA components via the FAK/Src pathway. We also demonstrated that activation of the MRTF-dependent transcription correlates FAK activation in various tumor cells. The elucidation of the correlation between MRTF and FAK activities would be an effective therapeutic target in focus of tumor cell migration. PMID- 27708221 TI - PRMT5 competitively binds to CDK4 to promote G1-S transition upon glucose induction in hepatocellular carcinoma. AB - Although cancer cells are known to be "addicted" to glucose, the effect of glucose in proliferation of these cells remains elusive. Here, we report that upon glucose induction, protein arginine methyltransferase 5 (PRMT5) exerts a profound effect on the G1-S cell cycle progression via directly interacting with cyclin dependent kinase 4 (CDK4) in hepatocellular carcinoma (HCC). Upregulation of both PRMT5 and CDK4 predicts more malignant characteristics in human HCC tissues. Mechanistically, glucose promotes the interaction between PRMT5 and CDK4, which leads to activation of CDK4-RB-E2F-mediated transcription via releasing CDKN2A from CDK4. Moreover, the PRMT5 competitive inhibition of the interaction between CDK4 and CDKN2A is important for glucose-induced growth of HCC cells. Furthermore, the CDK4 mutant R24A weakly binds to PRMT5, inhibiting HCC cell cycle progression and tumor growth. Thus, our findings uncover a critical function for PRMT5 and CDK4 and provide an improved therapeutic strategy against HCC. PMID- 27708223 TI - Differential effects of peptidoglycan on colorectal tumors and intestinal tissue post-pelvic radiotherapy. AB - Immediate medical intervention is required after pelvic tumor radiotherapy to protect the radiosensitive intestine and also to mitigate tumor growth. Toll-like receptors (TLRs) have been shown to promote tissue repair processes. Here, we analyzed the effect observed upon combining the TLR2 agonist, peptidoglycan (PGN), with radiation therapy on tumors as well as intestinal tissue, both in vitro and in vivo. In contrast to radiotherapy alone, PGN when combined with ionizing radiation (IR) elicited enhanced antitumor effects and also reduced the IR-induced intestinal damage. Mechanistic studies showed that PGN first induced an IL13 response in the irradiated intestine, but was decreased in tumor cell models screened by Th1/Th2 FlowCytomix assay and validated by the application of IL13 and anti-IL13 neutralizing antibodies. Next, PGN stimulated Akt3, but not Akt1/2, as was verified by AKT1/2/3 plasmid transfection assay and in AKT1/2/3 knockout mice in vivo. Akt3 expression was inhibited in 20 MUg/mL PGN-treated tumor cells and in 1.5 mg/kg PGN-treated mouse tumor models. However, Akt3 was raised via IL13 in the irradiated intestine and human intestinal cell line after the same treatment. Finally, PGN activated mTOR via IL13/AKT3 in the intestine and restored intestinal structure and function. As an adjuvant to radiotherapy, PGN inhibited tumorigenesis by suppression of mTOR activity. To summarize, the IL13/AKT3/mTOR pathway was lessened in PGN-treated irradiated tumors but was raised in the normal intestine tissue. This distinct effect of PGN on normal and tumor tissues during pelvic radiotherapy suggests that PGN may be a promising adjuvant therapy to radiation. PMID- 27708222 TI - Epithelial cells captured from ductal carcinoma in situ reveal a gene expression signature associated with progression to invasive breast cancer. AB - Breast cancer biomarkers that can precisely predict the risk of progression of non-invasive ductal carcinoma in situ (DCIS) lesions to invasive disease are lacking. The identification of molecular alterations that occur during the invasion process is crucial for the discovery of drivers of transition to invasive disease and, consequently, biomarkers with clinical utility. In this study, we explored differences in gene expression in mammary epithelial cells before and after the morphological manifestation of invasion, i.e., early and late stages, respectively. In the early stage, epithelial cells were captured from both pre-invasive lesions with distinct malignant potential [pure DCIS as well as the in situ component that co-exists with invasive breast carcinoma lesions (DCIS-IBC)]; in the late stage, epithelial cells were captured from the two distinct morphological components of the same sample (in situ and invasive components). Candidate genes were identified using cDNA microarray and rapid subtractive hybridization (RaSH) cDNA libraries and validated by RT-qPCR assay using new samples from each group. These analyses revealed 26 genes, including 20 from the early and 6 from the late stage. The expression profile based on the 20 genes, marked by a preferential decrease in expression level towards invasive phenotype, discriminated the majority of DCIS samples. Thus, this study revealed a gene expression signature with the potential to predict DCIS progression and, consequently, provides opportunities to tailor treatments for DCIS patients. PMID- 27708224 TI - A module of inflammatory cytokines defines resistance of colorectal cancer to EGFR inhibitors. AB - Epidermal Growth Factor Receptor (EGFR) activates a robust signalling network to which colon cancer tumours often become addicted. Cetuximab, one of the monoclonal antibodies targeting this pathway, is employed to treat patients with colorectal cancer. However, many patients are intrinsically refractory to this treatment, and those who respond develop secondary resistance along time. Mechanisms of cancer cell resistance include either acquisition of new mutations or non genomic activation of alternative signalling routes. In this study, we employed a colon cancer model to assess potential mechanisms driving resistance to cetuximab. Resistant cells displayed increased ability to grow in suspension as colonspheres and this phenotype was associated with poorly organized structures. Factors secreted from resistant cells were causally involved in sustaining resistance, indeed administration to parental cells of conditioned medium collected from resistant cells was sufficient to reduce cetuximab efficacy. Among secreted factors, we report herein that a signature of inflammatory cytokines, including IL1A, IL1B and IL8, which are produced following EGFR pathway activation, was associated with the acquisition of an unresponsive phenotype to cetuximab in vitro. This signature correlated with lack of response to EGFR targeting also in patient-derived tumour xenografts. Collectively, these results highlight the contribution of inflammatory cytokines to reduced sensitivity to EGFR blockade and suggest that inhibition of this panel of cytokines in combination with cetuximab might yield an effective treatment strategy for CRC patients refractory to anti-EGFR targeting. PMID- 27708226 TI - Mitochondrial dysfunction enhances cisplatin resistance in human gastric cancer cells via the ROS-activated GCN2-eIF2alpha-ATF4-xCT pathway. AB - Mitochondrial DNA mutations and defects in mitochondrial enzymes have been identified in gastric cancers, and they might contribute to cancer progression. In previous studies, mitochondrial dysfunction was induced by oligomycin-enhanced chemoresistance to cisplatin. Herein, we dissected the regulatory mechanism for mitochondrial dysfunction-enhanced cisplatin resistance in human gastric cancer cells. Repeated cisplatin treatment-induced cisplatin-resistant cells exhibited high SLC7A11 (xCT) expression, and xCT inhibitors (sulfasalazine or erastin), xCT siRNA, or a GSH synthesis inhibitor (buthionine sulphoximine, BSO) could sensitize these cells to cisplatin. Clinically, the high expression of xCT was associated with a poorer prognosis for gastric cancer patients under adjuvant chemotherapy. Moreover, we found that mitochondrial dysfunction enhanced cisplatin resistance and up-regulated xCT expression, as well as intracellular glutathione (GSH). The xCT inhibitors, siRNA against xCT or BSO decreased mitochondrial dysfunction-enhanced cisplatin resistance. We further demonstrated that the upregulation of the eIF2alpha-ATF4 pathway contributed to mitochondrial dysfunction-induced xCT expression, and activated eIF2alpha kinase GCN2, but not PERK, stimulated the eIF2alpha-ATF4-xCT pathway in response to mitochondrial dysfunction-increased reactive oxygen species (ROS) levels. In conclusion, our results suggested that the ROS-activated GCN2-eIF2alpha-ATF4-xCT pathway might contribute to mitochondrial dysfunction-enhanced cisplatin resistance and could be a potential target for gastric cancer therapy. PMID- 27708225 TI - NSAID-activated gene 1 mediates pro-inflammatory signaling activation and paclitaxel chemoresistance in type I human epithelial ovarian cancer stem-like cells. AB - Epithelial ovarian cancer (EOC) remains the most lethal gynecologic malignancy in developed countries. Chronic endogenous sterile pro-inflammatory responses are strongly linked to EOC progression and chemoresistance to anti-cancer therapeutics. In the present study, the activity of epithelial NF-kappaB, a key pro-inflammatory transcription factor, was enhanced with the progress of EOC. This result was mechanistically linked with an increased expression of NSAID Activated Gene 1 (NAG-1) in MyD88-positive type I EOC stem-like cells, compared with that in MyD88-negative type II EOC cells. Elevated NAG-1 as a potent biomarker of poor prognosis in the ovarian cancer was positively associated with the levels of NF-kappaB activation, chemokines and stemness markers in type I EOC cells. In terms of signal transduction, NAG-1-activated SMAD-linked and non canonical TGFbeta-activated kinase 1 (TAK-1)-activated pathways contributed to NF kappaB activation and the subsequent induction of some chemokines and cancer stemness markers. In addition to effects on NF-kappaB-dependent gene regulation, NAG-1 was involved in expression of EGF receptor and subsequent activation of EGF receptor-linked signaling. The present study also provided evidences for links between NAG-1-linked signaling and chemoresistance in ovarian cancer cells. NAG-1 and pro-inflammatory NF-kappaB were positively associated with resistance to paclitaxel in MyD88-positive type I EOC cells. Mechanistically, this chemoresistance occurred due to enhanced activation of the SMAD-4- and non-SMAD TAK-1-linked pathways. All of the present data suggested NAG-1 protein as a crucial mediator of EOC progression and resistance to the standard first-line chemotherapy against EOC, particularly in MyD88-positive ovarian cancer stem-like cells. PMID- 27708227 TI - T-cell responses against CD19+ pediatric acute lymphoblastic leukemia mediated by bispecific T-cell engager (BiTE) are regulated contrarily by PD-L1 and CD80/CD86 on leukemic blasts. AB - T-cell immunotherapies are promising options in relapsed/refractory B-precursor acute lymphoblastic leukemia (ALL). We investigated the effect of co-signaling molecules on T-cell attack against leukemia mediated by CD19/CD3-bispecific T cell engager. Primary CD19+ ALL blasts (n>=10) and physiologic CD19+CD10+ bone marrow precursors were screened for 20 co-signaling molecules. PD-L1, PD-1, LAG 3, CD40, CD86, CD27, CD70 and HVEM revealed different stimulatory and inhibitory profiles of pediatric ALL compared to physiologic cells, with PD-L1 and CD86 as most prominent inhibitory and stimulatory markers. PD-L1 was increased in relapsed ALL patients (n=11) and in ALLs refractory to Blinatumomab (n=5). Exhaustion markers (PD-1, TIM-3) were significantly higher on patients' T cells compared to physiologic controls. T-cell proliferation and effector function was target-cell dependent and correlated to expression of co-signaling molecules. Blockade of inhibitory PD-1-PD-L and CTLA-4-CD80/86 pathways enhanced T-cell function whereas blockade of co-stimulatory CD28-CD80/86 interaction significantly reduced T-cell function. Combination of Blinatumomab and anti-PD-1 antibody was feasible and induced an anti-leukemic in vivo response in a 12-year old patient with refractory ALL. In conclusion, ALL cells actively regulate T cell function by expression of co-signaling molecules and modify efficacy of therapeutic T-cell attack against ALL. Inhibitory interactions of leukemia induced checkpoint molecules can guide future T-cell therapies. PMID- 27708228 TI - SIRT1-mediated downregulation of p27Kip1 is essential for overcoming contact inhibition of Kaposi's sarcoma-associated herpesvirus transformed cells. AB - Kaposi's sarcoma-associated herpesvirus (KSHV) is an oncogenic virus associated with Kaposi's sarcoma (KS), a malignancy commonly found in AIDS patients. Despite intensive studies in the last two decades, the mechanism of KSHV-induced cellular transformation and tumorigenesis remains unclear. In this study, we found that the expression of SIRT1, a metabolic sensor, was upregulated in a variety of KSHV infected cells. In a model of KSHV-induced cellular transformation, SIRT1 knockdown with shRNAs or knockout by CRISPR/Cas9 gene editing dramatically suppressed cell proliferation and colony formation in soft agar of KSHV transformed cells by inducing cell cycle arrest and contact inhibition. SIRT1 knockdown or knockout induced the expression of cyclin-dependent kinase inhibitor 1B (p27Kip1). Consequently, p27 knockdown rescued the inhibitory effect of SIRT1 knockdown or knockout on cell proliferation and colony formation. Furthermore, treatment of KSHV-transformed cells with a SIRT1 inhibitor, nicotinamide (NAM), had the same effect as SIRT1 knockdown and knockout. NAM significantly inhibited cell proliferation in culture and colony formation in soft agar, and induced cell cycle arrest. Significantly, NAM inhibited the progression of tumors and extended the survival of mice in a KSHV-induced tumor model. Collectively, these results demonstrate that SIRT1 suppression of p27 is required for KSHV-induced tumorigenesis and identify a potential therapeutic target for KS. PMID- 27708229 TI - Prognostic effect of intratumoral neutrophils across histological subtypes of non small cell lung cancer. AB - Recent data indicate that tumor-associated neutrophils (TANs) serve a dual role in tumor progression and regression. CD66b is a neutrophil marker and has been associated with patient outcome in various cancers. However, its clinical impact in non-small cell lung cancer (NSCLC) remains controversial. 536 NSCLC patients, of which 172 harbored lymph node metastases, were included in this study. Tissue microarrays were constructed and multiplexed immunohistochemistry of CD66b, CD34 and pan-keratin was performed to evaluate the localization and quantity of CD66b+ TANs. High intratumoral CD66b+ TANs density in squamous cell carcinoma (SCC) subgroup was an independent positive prognosticator for disease-specific survival (P = 0.038). In contrast, high intratumoral TANs density was an independent negative prognostic factor in the adenocarcinoma (ADC) subgroup (P= 0.032). Likewise, in ADC patients with lymph node metastases, high level of intratumoral TANs was associated with poor prognosis (P = 0.003). Stromal CD66b+ TANs were not associated with outcome of NSCLC patients. In conclusion, CD66b+ TANs show diverging prognostic effect in NSCLC patients according to histological subgroups. The presence of CD66b+ TANs could prove pivotal for development of an immunoscore in ADC NSCLC patients. PMID- 27708230 TI - Cytomorphological characteristics of glassy cell carcinoma of the uterine cervix: histopathological correlation and human papillomavirus genotyping. AB - A retrospective analysis was performed to describe the cytomorphological and histopathological findings and human papillomavirus (HPV) genotypes for glassy cell carcinoma (GCC) of the uterine cervix. Five cases of cervical GCC, in which the glassy cell features constituted at least 95% of the specimen, were included. Four patients had stage IIB GCCs and one had stage IIIB GCC. All patients underwent concurrent chemoradiation therapy. Based on pretreatment cytology, only 1 of the 5 cases was correctly diagnosed as GCC. The remaining cases were diagnosed as carcinoma of undetermined type, adenocarcinoma, poorly differentiated carcinoma, or unsatisfactory for evaluation. Cytological specimens had moderate cellularity and contained small clusters of tumor cells admixed with amphophilic, granular tumor diathesis. The tumor cells possessed large, round to oval nuclei and abundant, granular, ground-glass cytoplasm. The nuclei exhibited prominent eosinophilic nucleoli. The cytoplasm displayed sharp margins and molding, resulting in "intercellular windows" between neighboring attached cells. HPV genotyping revealed that high-risk HPV types 18, 16, and 31 were detected in 3, 1, and 1 cases, respectively. Consistent with this finding, all cases exhibited block p16 positivity, confirming the association of HPV infection with GCC. In conclusion, a distinct cytoplasmic margin, the characteristic histopathological feature of GCC, was observed in liquid-based cytological preparations. We suggest that sharp cytoplasmic outlines with molding and intercellular windows are characteristic cytomorphological features of GCC. Detection of high-risk HPV in all cases strongly supported the notion that high risk HPV is involved in the pathogenesis of GCC. PMID- 27708231 TI - Deregulation of the pRb-E2F4 axis alters epidermal homeostasis and favors tumor development. AB - E2F/RB activity is altered in most human tumors. The retinoblastoma family of proteins plays a key role in regulating the progression of the cell cycle from the G1 to S phases. This is achieved through negative regulation of E2F transcription factors, important positive regulators of cell cycle entry. E2F family members are divided into two groups: activators (E2F1-E2F3a) and repressors (E2F3b-E2F8). E2F4 accounts for a large part of the E2F activity and is a main E2F repressor member in vivo. Perturbations in the balance from quiescence towards proliferation contribute to increased mitotic gene expression levels frequently observed in cancer. We have previously reported that combined Rb1-Rbl1 or Rb1-E2f1 ablation in epidermis produces important alterations in epidermal proliferation and differentiation, leading to tumor development. However, the possible roles of E2F4 in this context are still to be determined. Here, we show the absence of any discernible phenotype in the skin of mice lacking of E2f4. In contrast, the inducible loss of Rb1 in the epidermis of E2F4 null mice produced multiple skin abnormalities including altered differentiation and proliferation, spontaneous wounds, carcinoma in situ development and stem cell perturbations. All these phenotypic alterations are associated with extensive gene expression changes, the induction of c-myc and the Akt activation. Moreover the whole transcriptome analyses in comparison with previous models generated also revealed extensive changes in multiple repressive complexes and in transcription factor activity. These results point to E2F4 as a master regulator in multiple steps of epidermal homeostasis in Rb1 absence. PMID- 27708232 TI - A strong host response and lack of MYC expression are characteristic for diffuse large B cell lymphoma transformed from nodular lymphocyte predominant Hodgkin lymphoma. AB - Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is an indolent lymphoma, but can transform into diffuse large B cell lymphoma (DLBCL), showing a more aggressive clinical behavior. Little is known about these cases on the molecular level. Therefore, the aim of the present study was to characterize DLBCL transformed from NLPHL (LP-DLBCL) by gene expression profiling (GEP). GEP revealed an inflammatory signature pinpointing to a specific host response. In a coculture model resembling this host response, DEV tumor cells showed an impaired growth behavior. Mechanisms involved in the reduced tumor cell proliferation included a downregulation of MYC and its target genes. Lack of MYC expression was also confirmed in 12/16 LP-DLBCL by immunohistochemistry. Furthermore, CD274/PD L1 was upregulated in DEV tumor cells after coculture with T cells or monocytes and its expression was validated in 12/19 cases of LP-DLBCL. Thereby, our data provide new insights into the pathogenesis of LP-DLBCL and an explanation for the relatively low tumor cell content. Moreover, the findings suggest that treatment of these patients with immune checkpoint inhibitors may enhance an already ongoing host response in these patients. PMID- 27708233 TI - Advanced lung adenocarcinomas with ROS1-rearrangement frequently show hepatoid cell. AB - Defining distinctive histologic characteristics of ROS1-rearranged non-small-cell lung carcinomas (NSCLCs) may help identify cases that merit molecular testing. However, the majority of previous reports have focused on surgical specimens but only limited studies assessed histomorphology of advanced NSCLCs. In order to identify the clinical and histological characteristics of ROS1-rearranged advanced NSCLCs, we examined five hundred sixteen Chinese patients with advanced NSCLCs using ROS1 fluorescence in situ hybridization and real-time polymerase chain reaction and then analyzed for clinical and pathological features. We performed univariate and multivariate analyses to identify predictive factors associated with ROS1 rearrangement. 19 tumors were identified with ROS1 rearrangement (3.7% of adenocarcinomas). 16 ROS1+ and 122 ROS1- samples with available medical records and enough tumor cells were included for histological analysis. Compared with ROS1-negative advanced NSCLCs,ROS1-rearranged advanced NSCLCs were associated with a younger age at presentation. ROS1 rearrangements were not significantly associated with sex, smoking history, drinking history and metastatic sites. The most common histological pattern was solid growth (12/16), followed by acinar (4/16) growth. 66.7% cases with solid growth pattern showed hepatoid cytology (8/12) and 75% cases with acinar growth pattern showed a cribriform structure (3/4). 18.8% cases were found to have abundant extracellular mucus or signet-ring cells (3/16). Only one case with solid growth pattern showed psammomatous calcifications. In conclusion, age, hepatoid cytology and cribriform structure are the independent predictors for ROS1-rearranged advanced NSCLCs, recognizing these may be helpful in finding candidates for genomic alterations, especially when available tissue samples are limited. PMID- 27708234 TI - Plasma and tumor levels of Linc-pint are diagnostic and prognostic biomarkers for pancreatic cancer. AB - Long intergenic non-protein coding RNA, p53 induced transcript (Linc-pint) is a long noncoding RNA (lncRNA) that regulates tumor cell viability and proliferation. We used qRT-PCR and RNA FISH analysis to evaluate Linc-pint levels in the plasma and tumor tissues of pancreatic cancer (PCa) patients. Our data demonstrate that Linc-pint expression is lower in plasma samples from PCa patients than from healthy individuals, and indicate that plasma Linc-pint levels are more sensitive than CA19-9 for detecting PCa. Our data also show that Linc pint levels are lower in PCa tumors than in adjacent tissues, carcinoma of the ampulla of Vater (CAV) and cholangiocarcinoma (CCA), and suggest that Linc-pint could be used for distinguishing the cause of malignant obstructive jaundice. Low plasma Linc-pint levels correlate with tumor recurrence, while low tumor Linc pint levels correlate with poor prognosis for PCa patients after pancreatectomy. These results thus indicate that low plasma Linc-pint expression could serve as a minimally invasive biomarker for early PCa detection, and that low Linc-pint levels in PCa tumors could be used for predicting patient prognosis. PMID- 27708235 TI - A next-generation bifunctional photosensitizer with improved water-solubility for photodynamic therapy and diagnosis. AB - Photodynamic therapy (PDT) exploits light interactions and photosensitizers to induce cytotoxic reactive oxygen species. Photodynamic diagnosis (PDD) uses the phenomenon of photosensitizer emitting fluorescence to distinguish some tumors from normal tissue. The standard photosensitizer used for PDD is 5-aminolevulinic acid (5-ALA), although it is not entirely satisfactory. We previously reported glucose-conjugated chlorin (G-chlorin) as a more effective photosensitizer than another widely used photosensitizer, talaporfin sodium (TS); however, G-chlorin is hydrophobic. We synthesized oligosaccharide-conjugated chlorin (O-chlorin) with improved water-solubility. We report herein on its accumulation and cytotoxicity. O-chlorin was synthesized and examined for solubility. Flow cytometric analysis was performed to evaluate O-chlorin accumulation in cancer cells. To evaluate the intracellular localization of photosensitizer, cells were stained with O-chlorin and organelle-specific fluorescent probes. We then measured the in vitro fluorescence of various photosensitizers and the half maximal inhibitory concentrations to evaluate effects in PDD and PDT, respectively. Xenograft tumor models were established, and antitumor and visibility effects were analyzed. O-chlorin was first shown to be hydrophilic. Flow cytometry then revealed a 20- to 40-times higher accumulation of O-chlorin in cancer cells than of TS, and a 7- to 23-times greater fluorescence than 5-ALA. In vitro, the cytotoxicity of O-chlorin PDT was stronger than that of TS PDT, and O-chlorin tended to accumulate in lysosomes. In vivo, O-chlorin showed the best effect in PDT and PDD compared to other photosensitizers.O-chlorin was hydrophilic and showed excellent tumor accumulation and fluorescence. O-chlorin is promising as a next-generation bifunctional photosensitizer candidate for both PDT and PDD. PMID- 27708236 TI - Engineering of double recombinant vaccinia virus with enhanced oncolytic potential for solid tumor virotherapy. AB - Vaccinia virus (VACV) oncolytic therapy has been successful in a number of tumor models. In this study our goal was to generate a double recombinant vaccinia virus (VV-GMCSF-Lact) with enhanced antitumor activity that expresses exogenous proteins: the antitumor protein lactaptin and human granulocyte-macrophage colony stimulating factor (GM-CSF). Lactaptin has previously been demonstrated to act as a tumor suppressor in mouse hepatoma as well as MDA-MB-231 human adenocarcinoma cells grafted into SCID mice. VV-GMCSF-Lact was engineered from Lister strain (L IVP) vaccinia virus and has deletions of the viral thymidine kinase and vaccinia growth factor genes. Cell culture experiments revealed that engineered VV-GMCSF Lact induced the death of cultured cancer cells more efficiently than recombinant VACV coding only GM-CSF (VV-GMCSF-dGF). Normal human MCF-10A cells were resistant to both recombinants up to 10 PFU/cell. The selectivity index for breast cancer cells measured in pair cultures MCF-7/MCF-10A was 200 for recombinant VV-GMCSF Lact coding lactaptin and 100 for VV-GMCSF-dGF. Using flow cytometry we demonstrated that both recombinants induced apoptosis in treated cells but that the rate in the cells with active caspase-3 and -7 was higher after treatment with VV-GMCSF-Lact than with VV-GMCSF-dGF. Tumor growth inhibition and survival outcomes after VV-GMCSF-Lact treatment were estimated using immunodeficient and immunocompetent mice models. We observed that VV-GMCSF-Lact efficiently delays the growth of sensitive and chemoresistant tumors. These results demonstrate that recombinant VACVs coding an apoptosis-inducing protein have good therapeutic potential against chemoresistant tumors. Our data will also stimulate further investigation of coding lactaptin double recombinant VACV in clinical settings. PMID- 27708237 TI - Proteomic identification of the lactate dehydrogenase A in a radioresistant prostate cancer xenograft mouse model for improving radiotherapy. AB - Radioresistance is a major challenge for prostate cancer (CaP) metastasis and recurrence after radiotherapy. This study aimed to identify potential protein markers and signaling pathways associated with radioresistance using a PC-3 radioresistant (RR) subcutaneous xenograft mouse model and verify the radiosensitization effect from a selected potential candidate. PC-3RR and PC-3 xenograft tumors were established and differential protein expression profiles from two groups of xenografts were analyzed using liquid chromatography tandem mass spectrometry. One selected glycolysis marker, lactate dehydrogenase A (LDHA) was validated, and further investigated for its role in CaP radioresistance. We found that 378 proteins and 51 pathways were significantly differentially expressed between PC-3RR and PC-3 xenograft tumors, and that the glycolysis pathway is closely linked with CaP radioresistance. In addition, we also demonstrated that knock down of LDHA with siRNA or inhibition of LDHA activity with a LDHA specific inhibitor (FX-11), could sensitize PC-3RR cells to radiotherapy with reduced epithelial-mesenchymal transition, hypoxia, DNA repair ability and autophagy, as well as increased DNA double strand breaks and apoptosis. In summary, we identified a list of potential RR protein markers and important signaling pathways from a PC-3RR xenograft mouse model, and demonstrate that targeting LDHA combined with radiotherapy could increase radiosensitivity in RR CaP cells, suggesting that LDHA is an ideal therapeutic target to develop combination therapy for overcoming CaP radioresistance. PMID- 27708238 TI - Isoliquiritigenin induces apoptosis and autophagy and inhibits endometrial cancer growth in mice. AB - Endometrial cancer is the most common cancer in women, typically with onset after menopause. Isoliquiritigenin (ISL), a licorice flavonoid, was previously shown to have anti-oxidant, anti-inflammatory, and tumor suppression effects. In this study, we investigated the anti-tumor effect of ISL on human endometrial cancer both in vitro and in vivo. We used telomerase-immortalized human endometrial stromal cells (T-HESCs) and human endometrial cancer cell lines (Ishikawa, HEC 1A, and RL95-2 cells) as targets. The effects of ISL on cell proliferation, cell cycle regulation, and apoptosis or autophagy-related protein expression were examined. In addition, we conducted in vivo experiments to confirm the inhibitory effects of ISL on cancer cells. ISL significantly inhibited the viability of cancer cells in a dose- and time-dependent manner but with little toxicity on normal cells. In addition, flow cytometry analysis indicated that ISL induced sub G1 or G2/M phase arrest. ISL treatment activated the extracellular signal regulated kinase signaling pathway to enhance the protein expression of caspase 7/LC3BII associated with apoptosis/autophagy. Furthermore, ISL suppressed xenograft tumor growth in vivo. Taken together, these findings suggest that ISL may induce apoptosis, autophagy, and cell growth inhibition, indicating its potential as a therapeutic agent for human endometrial cancer. PMID- 27708240 TI - Overexpression and potential roles of NRIP1 in psoriasis. AB - Nuclear receptor interacting protein 1 (NRIP1, also known as RIP140) is a co regulator for various transcriptional factors and nuclear receptors, and has been shown to take part in many biological and pathological processes, such as regulating mammary gland development and inflammatory response.The aim of this study is to investigate the expression of NRIP1 and to explore its roles in the pathogenesis of psoriasis. Thirty active psoriasis patients and 16 healthy volunteers were enrolled for this study. qRT-PCR analyses found that both NRIP1 and RelA/p65 were elevated in psoriatic lesions compared to psoriatic non-lesions and normal controls, and also overexpressed in peripheral blood mononuclear cell (PBMCs) of psoriasis patients. Suppression of NRIP1 in HaCaT cells could significantly inhibit cell growth and induce apoptosis, and the suppression of NRIP1 in CD4+ T cells isolated from psoriasis patients could downregulate the expression of RelA/p65 and decrease the secretion of IL-17. Furthermore, in Nrip1 knockout mice, IMQ-induced inflammation of skin was delayed and the RelA/p65 expression in lesions was reduced. In conclusion, our data suggests that NRIP1 is overexpressed both in skin and PBMCs of psoriasis patients and may be involved in the abnormal proliferation and apoptosis of keratinocytes, as well as the immune reaction through the regulation of RelA/p65. Therefore, NRIP1 may be a potential therapeutic target for psoriasis. PMID- 27708239 TI - FOXC1 identifies basal-like breast cancer in a hereditary breast cancer cohort. AB - Breast cancers arising in the setting of the hereditary breast cancer genes BRCA1 and BRCA2 are most commonly classified as basal-like breast cancer (BLBC) or luminal breast cancer, respectively. BLBC is an aggressive subtype of breast cancer associated with liver and lung metastases and poorer prognosis than other subtypes and for which chemotherapy is the only systemic therapy. Multiple immunohistochemical markers are used to identify the basal-like subtype, including the absence of estrogen receptor alpha, progesterone receptor, and human epidermal growth factor receptor 2. Forkhead box C1 (FOXC1) has been identified as a specific marker expressed in BLBC in general breast cancer cohorts. We examined an institutional cohort of breast cancer patients with germline BRCA1 (n=46) and BRCA2 (n=35) mutations and found that FOXC1 expression on immunohistochemical staining is associated with BRCA1 vs BRCA2 mutations [30/46 vs. 6/35]. In BRCA1 mutant tumors, FOXC1 was expressed in 28/31 BLBC tumors and 2/13 non-BLBC tumors, In BRCA2 mutant tumors, FOXC1 was expressed in 5/5 BLBC tumors and 1/30 non-BLBC tumors. In cell culture models of BRCA1-mutant breast cancer, FOXC1 is associated with increased proliferation and may serve as a marker for sensitivity to PARP-inhibitor therapy with olaparib. PMID- 27708241 TI - Hepatitis B virus X induces inflammation and cancer in mice liver through dysregulation of cytoskeletal remodeling and lipid metabolism. AB - Hepatitis B virus X protein (HBx) participates in the occurrence and development processes of hepatocellular carcinoma (HCC) as a multifunctional regulation factor. However, the underlying molecular mechanism remains obscure. Here, we describe the use of p21HBx/+ mouse and SILAM (Stable Isotope Labeling in Mammals) strategy to define the pathological mechanisms for the occurrence and development of HBx induced liver cancer. We systematically compared a series of proteome samples from regular mice, 12- and 24-month old p21HBx/+ mice representing the inflammation and HCC stages of liver disease respectively and their nontransgenic wild-type (WT) littermates. Totally we identified 22 and 97 differentially expressed proteins out of a total of 2473 quantified proteins. Bioinformatics analysis suggested that the lipid metabolism and CDC42-induced cytoskeleton remodeling pathways were strongly activated by the HBx transgene. Interestingly, the protein-protein interaction MS study revealed that HBx directly interacted with multiple proteins in these two pathways. The same effect of up-regulation of cytoskeleton and lipid metabolism related proteins, including CDC42, CFL1, PPARgamma and ADFP, was also observed in the Huh-7 cells transfected with HBx. More importantly, CFL1 and ADFP were specifically accumulated in HBV-associated HCC (HBV-HCC) patient samples, and their expression levels were positively correlated with the severity of HBV-related liver disease. These results provide evidence that HBx induces the dysregulation of cytoskeleton remodeling and lipid metabolism and leads to the occurrence and development of liver cancer. The CFL1 and ADFP might be served as potential biomarkers for prognosis and diagnosis of HBV-HCC. PMID- 27708242 TI - Early responses of EGFR circulating tumor DNA to EGFR tyrosine kinase inhibitors in lung cancer treatment. AB - OBJECTIVES: Early evaluation of the effect of treatment is helpful in the management of cancer patients. Circulating biomarkers are an ideal tool for this if they are highly specific to tumors and respond rapidly to tumor volume changes. Circulating tumor DNA (ctDNA) is one such candidate. We conducted a prospective study to test the utility of EGFR ctDNA in early evaluation of EGFR TKI effects. RESULTS: Twenty-one patients with EGFR-mutant lung cancer who were naive to EGFR-TKI were enrolled. PM scores of EGFR ctDNA with activating mutations decreased rapidly in response to EGFR-TKI. Of the 14 patients with positive pretreatment PM scores, complete disappearance of major EGFR ctDNA was observed in 14.3%, 42.9%, and 57.1% on days 2 - 4, 8, and 15, respectively. These responses of EGFR ctDNA were most prominent among the measures used to evaluate responses, and correlated with early radiologic responses evaluated by chest X rays. MATERIALS AND METHODS: EGFR ctDNA in serial plasma samples was amplified and 105 copies were sequenced with a next-generation sequencer. Plasma mutation (PM) score was defined as the number of reads containing deletions/substitutions in 105EGFR cell free DNA (cfDNA). When EGFR mutation in ctDNA was the same as that detected in cancer tissue, the ctDNA was defined as major EGFR ctDNA. CONCLUSIONS: The results indicate the usefulness of ctDNA as a highly specific biomarker for prediction of early response to treatment and that it can be applied to various types of cancer. PMID- 27708243 TI - JWA down-regulates HER2 expression via c-Cbl and induces lapatinib resistance in human gastric cancer cells. AB - Human epidermal growth factor receptor 2 (HER2) targeted therapy is currently considered as the standard treatment for HER2-positive advanced gastric cancer (GC). However, unsatisfactory results of recent phase III clinical trials involving lapatinib suggested biomarkers for selection of patients. The aim of this study was to identify JWA as a biomarker for lapatinib resistance in GC cells and elucidate the underlying mechanisms. Lapatinib was effective to the intrinsic cisplatin-resistant GC cells. JWA activation conferred lapatinib unresponsiveness, but reversed cisplatin resistance in GC cells. Whereas, deletion of JWA significantly restored lapatinib suppression on proliferation and lapatinib-induced apoptosis. JWA-induced down-regulation of HER2 and activation of ERK phosphorylation led to lapatinib resistance. Furthermore, c-Cbl represented a novel mechanism for HER2 degradation enhanced by JWA in GC cells. Taken together, JWA is a potential predictive marker for lapatinib resistance, targeting the patients that may benefit from lapatinib treatment in human GC. PMID- 27708244 TI - Hypoxia pathway and hypoxia-mediated extensive extramedullary hematopoiesis are involved in ursolic acid's anti-metastatic effect in 4T1 tumor bearing mice. AB - Hypoxic in the tumor mass is leading to the myeloproliferative-like disease (leukemoid reaction) and anemia of body, which characterized by strong extensive extramedullary hematopoiesis (EMH) in spleen. As the key transcription factor of hypoxia, hypoxia-inducible factor-1 (HIF-1) activates the expression of genes essential for EMH processes including enhanced blood cell production and angiogenesis. We found ursolic acid (UA), a natural pentacyclic triterpenoid carboxylic acid, inhibited growth of breast cancer both in vivo and in vitro. The suppression was mediated through the inhibition of multiple cell pathways linked to inflammation, proliferation, angiogenesis, and metastasis. UA also suppressed the leukemoid reaction and the EMH phenomenon of the tumor bearing mice without any significant suppression on body weight (i.p. by 20 mg/kg for 28 days). This is associated with the significant decrease in white blood cells (WBC), platelets (PLT) and spleen weight. During this process, we also detected the down regulation of cell proliferative genes (PCNA, and beta-catenin), and metastatic genes (VEGF, and HIF-1alpha), as well as the depression of nuclear protein intensity of HIF-1alpha. Furthermore, the expression of E2F1, p53 and MDM2 genes were increased in UA group when the VEGF and HIF-1alpha was over-expressed. Cancer cells were sensitive to UA treating after the silencing of HIF-1alpha and the response of Hypoxic pathway reporter to UA was suppressed when HIF-1alpha was over expressed. Overall, our results from experimental and predictive studies suggest that the anticancer activity of UA may be at least in part caused by suppressing the cancer hypoxia and hypoxia-mediated EMH. PMID- 27708245 TI - Chronic low-dose-rate ionising radiation affects the hippocampal phosphoproteome in the ApoE-/- Alzheimer's mouse model. AB - Accruing data indicate that radiation-induced consequences resemble pathologies of neurodegenerative diseases such as Alzheimer's. The aim of this study was to elucidate the effect on hippocampus of chronic low-dose-rate radiation exposure (1 mGy/day or 20 mGy/day) given over 300 days with cumulative doses of 0.3 Gy and 6.0 Gy, respectively. ApoE deficient mutant C57Bl/6 mouse was used as an Alzheimer's model. Using mass spectrometry, a marked alteration in the phosphoproteome was found at both dose rates. The radiation-induced changes in the phosphoproteome were associated with the control of synaptic plasticity, calcium-dependent signalling and brain metabolism. An inhibition of CREB signalling was found at both dose rates whereas Rac1-Cofilin signalling was found activated only at the lower dose rate. Similarly, the reduction in the number of activated microglia in the molecular layer of hippocampus that paralleled with reduced levels of TNFalpha expression and lipid peroxidation was significant only at the lower dose rate. Adult neurogenesis, investigated by Ki67, GFAP and NeuN staining, and cell death (activated caspase-3) were not influenced at any dose or dose rate. This study shows that several molecular targets induced by chronic low dose-rate radiation overlap with those of Alzheimer's pathology. It may suggest that ionising radiation functions as a contributing risk factor to this neurodegenerative disease. PMID- 27708246 TI - A novel DNA methylation score accurately predicts death from prostate cancer in men with low to intermediate clinical risk factors. AB - Clinically aggressive disease behavior is difficult to predict in men with low to intermediate clinical risk prostate cancer and methylation biomarkers may be a valuable adjunct for assessing the management of these patients. We set to evaluate the utility of DNA methylation to identify high risk disease in men currently considered as low or intermediate risk. DNA was extracted from formalin fixed paraffin-embedded transurethral prostate resection tissues collected during the years 1990-96 in a watchful-waiting cohort of men in the UK. The primary end point was death of prostate cancer, assessed by reviewing cancer registry records from 2009. Methylation was quantified by pyrosequencing assays for six genes (HSPB1, CCND2, TIG1, DPYS, PITX2, and MAL) with established biomarker value in prostate cancer. A novel prognostic methylation score was developed by multivariate Cox modelling using the six methylation biomarkers in 385 men with low-and-intermediate clinical risk variables and its prognostic value compared to two previously defined clinically-derived risk scores. Methylation score was the most significant variable in univariate and bivariate analysis in men with low-to intermediate CAPRA risk score. When combined with CAPRA score the hazard ratio was 2.02; 95% confidence interval, 1.40-2.92. For a methylation score sensitivity of 83% the specificity was 44%, while the maximum achieved sensitivity by CAPRA was 68% at a specificity of 44%. The derived methylation score is a strong predictor of aggressive prostate cancer that could have an important role in directing the management of patients with low-to-intermediate risk disease. The estimated areas under the curve (AUC) at 10 years of follow-up were 0.62 (95% CI: 0.51, 0.70) and 0.74 (95% CI: 0.65, 0.82) for CAPRA, and combined (CAPRA + methylation) risk score (CRS) respectively. PMID- 27708247 TI - Scriptaid overcomes hypoxia-induced cisplatin resistance in both wild-type and mutant p53 lung cancer cells. AB - Non-small cell lung cancer (NSCLC), comprising 85% of lung cancer cases, has been associated with resistance to chemo/radiotherapy. The hypoxic tumor micro environment, where insufficient vasculature results in poor drug penetrance and sub-optimal chemotherapy in the tumor interiors contributes heavily to this resistance. Additionally, epigenetic changes in tumorigenic cells also change their response to different forms of therapy. In our study, we have investigated the effectiveness of a combination of cisplatin with scriptaid [a pan-Histone Deacetylase inhibitor (HDACi)] in a model that mimics the tumor microenvironment of hypoxia and sub-lethal chemotherapy. Scriptaid synergistically increases the efficacy of cisplatin in normoxia as well as hypoxia, accompanied with reduced metastasis and enhanced DNA damage. Addition of scriptaid also overcomes the cisplatin resistance exhibited in lung cancer cells with stabilized hypoxia inducible factor 1 (HIF1)-alpha (mutant) and mutant p53. Molecular studies showed that the combination treatment increased apoptotic cell death in both normoxia and hypoxia with a dual role of p38MAPK. Together, our results suggest that the combination of low dose cisplatin and scriptaid is cytotoxic to NSCLC lines, can overcome hypoxia induced resistance and mutant p53- induced instability often associated with this cancer, and has the potential to be an effective therapeutic modality. PMID- 27708248 TI - Distinct biological effects of low-dose radiation on normal and cancerous human lung cells are mediated by ATM signaling. AB - Low-dose radiation (LDR) induces hormesis and adaptive response in normal cells but not in cancer cells, suggesting its potential protection of normal tissue against damage induced by conventional radiotherapy. However, the underlying mechanisms are not well established. We addressed this in the present study by examining the role of the ataxia telangiectasia mutated (ATM) signaling pathway in response to LDR using A549 human lung adenocarcinoma cells and HBE135-E6E7 (HBE) normal lung epithelial cells. We found that LDR-activated ATM was the initiating event in hormesis and adaptive response to LDR in HBE cells. ATM activation increased the expression of CDK4/CDK6/cyclin D1 by activating the AKT/glycogen synthase kinase (GSK)-3beta signaling pathway, which stimulated HBE cell proliferation. Activation of ATM/AKT/GSK-3beta signaling also increased nuclear accumulation of nuclear factor erythroid 2-related factor 2, leading to increased expression of antioxidants, which mitigated cellular damage from excessive reactive oxygen species production induced by high-dose radiation. However, these effects were not observed in A549 cells. Thus, the failure to activate these pathways in A549 cells likely explains the difference between normal and cancer cells in terms of hormesis and adaptive response to LDR. PMID- 27708249 TI - Downregulation of sphingosine kinase-1 induces protective tumor immunity by promoting M1 macrophage response in melanoma. AB - The infiltration of melanoma tumors by macrophages is often correlated with poor prognosis. However, the molecular signals that regulate the dialogue between malignant cells and the inflammatory microenvironment remain poorly understood. We previously reported an increased expression of sphingosine kinase-1 (SK1), which produces the bioactive lipid sphingosine 1-phosphate (S1P), in melanoma. The present study aimed at defining the role of tumor SK1 in the recruitment and differentiation of macrophages in melanoma. Herein, we show that downregulation of SK1 in melanoma cells causes a reduction in the percentage of CD206highMHCIIlow M2 macrophages in favor of an increased proportion of CD206lowMHCIIhigh M1 macrophages into the tumor. This macrophage differentiation orchestrates T lymphocyte recruitment as well as tumor rejection through the expression of Th1 cytokines and chemokines. In vitro experiments indicated that macrophage migration is triggered by the binding of tumor S1P to S1PR1 receptors present on macrophages whereas macrophage differentiation is stimulated by SK1 induced secretion of TGF-beta1. Finally, RNA-seq analysis of human melanoma tumors revealed a positive correlation between SK1 and TGF-beta1 expression. Altogether, our findings demonstrate that melanoma SK1 plays a key role in the recruitment and phenotypic shift of the tumor macrophages that promote melanoma growth. PMID- 27708250 TI - Targeting the ERK pathway for the treatment of Cushing's disease. AB - We recently demonstrated that the orphan nuclear receptor testicular receptor 4 (TR4) is a potent regulator of corticotroph tumor growth and hormone secretion. The Ras/Raf/MEK/ERK pathway is commonly overactivated in human tumors and we have demonstrated that corticotroph tumor TR4 is activated by ERK1/2-mediated phosphorylation. We evaluated effects of MEK-162, a selective, non-ATP competitive allosteric inhibitor of MEK1/2, on murine and human in vitro and in vivo corticotroph tumor proliferation and adrenocorticotrophic hormone (ACTH) secretion. MEK-162 treatment dose-dependently inhibited corticotroph tumor proliferation, induced apoptosis, reduced pro-opiomelanocortin (POMC) mRNA levels and inhibited ACTH secretion in vitro. Similar findings were obtained in human corticotroph tumor primary cultures (n = 5). These actions of MEK-162 were augmented in the presence of TR4 overexpression, suggesting that TR4 levels may serve as a predictive biomarker of MEK-162 corticotroph tumor responsiveness. Additionally, MEK-162 treatment reduced TR4 protein expression and blocked recruitment of TR4 to bind its consensus site on the POMC promoter (-854bp to 637bp), elucidating multiple mechanisms to control TR4 corticotroph tumor actions. In a murine corticotroph tumor in vivo model of Cushing's disease, MEK 162 treatment inhibited tumor growth and reduced tumor-derived circulating plasma ACTH, and corticosterone levels. These results demonstrate the potent actions of MEK-162 to inhibit corticotroph tumor growth and hormone secretion in vitro and in vivo via TR4-dependent and independent mechanisms, and raise the possibility of MEK-162 as a novel therapy for Cushing's disease.

AB - BACKGROUND: We aimed to measure the effect of raltegravir (RAL) on insulin sensitivity and surrogates of cardiovascular risk in healthy HIV-seronegative volunteers compared to that of lopinavir/r (LPV/r), a positive control. METHODS: An open-label, two phase crossover study in HIV-negative male subjects randomized 1:1 to receive either 2 weeks of LPV/r followed by a 2-week washout period and 2 weeks of RAL, or RAL initially followed by LPV/r. A hyperinsulinaemic euglycaemic clamp was performed prior to and following each 2-week dosing phase. Fasting samples for lipids, adiponectin, leptin, vascular inflammatory biomarkers and CD36 were also taken. RESULTS: A total of 16 subjects completed the study. At the baseline visit the mean insulin-stimulated glucose disposal per unit insulin (M/I) was 7.97 and 8.30 for LPV/r and RAL, respectively. The mean (sem) percentage change from baseline was -16.10% (3.84) after 2 weeks of LPV/r and 0.43% (4.83) after 2 weeks of RAL. Absolute M/I was 25% lower for LPV/r than for RAL (P=0.001). Triglycerides and total cholesterol rose significantly with LPV/r (+0.5 mmol/l, P=0.002 and +0.4 mmol/l, P<0.0001), but were unchanged with RAL. Proathrogenic lipid subfractions of low-density lipoprotein (LDL) cholesterol increased with LPV/r and were unaffected with RAL. LDL peak and mean particle diameter and LDL I significantly decreased with LPV/r (P<0.05), and trend of increased LDL III was detected. High-sensitivity C-reactive protein declined with RAL (-0.2 mg/l, P=0.043) but was elevated after LPV/r (+0.25 mg/l, P=0.03). CONCLUSIONS: RAL was not associated with measurable change in glycaemic, metabolic or inflammatory effects.

AB - BACKGROUND This study investigated how miR-21 expression is reflected in acute myocardial infarction and explored the role of miR-21 and the PTEN/VEGF signaling pathway in cardiac microvascular endothelial cells. MATERIAL AND METHODS We used an in vivo LAD rat model to simulate acute myocardial infarction. MiR-21 mimics and miR-21 inhibitors were injected and transfected into model rats in order to alter miR-21 expression. Cardiac functions were evaluated using echocardiographic measurement, ELISA, and Masson staining. In addition, lenti-PTEN and VEGF siRNA were transfected into CMEC cells using standard procedures for assessing the effect of PTEN and VEGE on cell proliferation, apoptosis, and angiogenesis. MiR 21, PTEN, and VEGF expressions were examined by RT-PCR and Western blot. The relationship between miR-21 and PTEN was determined by the luciferase activity assay. RESULTS We demonstrated that miR-21 bonded with the 3'-UTR of PTEN and suppressed PTEN expressions. Established models significantly induced cardiac infarct volume and endothelial injury marker expressions as well as miR-21 and PTEN expressions (P<0.05). MiR-21 mimics exhibited significantly protective effects since they down-regulated both infarction size and injury marker expressions by increasing VEGF expression and inhibiting PTEN expression (P<0.05). In addition, results from in vitro research show that lenti-PTEN and VEGF siRNA can notably antagonize the effect of miR-21 on cell proliferation, apoptosis, and angiogenesis (P<0.05). CONCLUSIONS MiR-21 exerts protective effects on endothelial injury through the PTEN/VEGF pathway after acute myocardial infarction. PMID- 27708253 TI - Unusual Complication of Pituitary Macroadenoma: A Case Report and Review. AB - BACKGROUND Pituitary macroadenoma is a common benign tumor that usually presents with visual field defects or hormonal abnormalities. Cerebral infarction can be a complication of a large pituitary adenoma. We report a rare case of bilateral anterior cerebral arteries infarcts by a large pituitary macroadenoma with apoplexy. CASE REPORT A 48-year-old male patient presented with altered conscious level and sudden loss of vision for one-day duration. Magnetic resonance imaging of the brain showed a large seller and suprasellar hemorrhagic mass of pituitary origin, with associated bilateral areas of diffusion restriction in the frontal parasagittal regions, consistent with infarctions. Magnetic resonance angiography showed elevation and compression of A1 segment of both anterior cerebral arteries by the hemorrhagic pituitary macroadenoma. The patient underwent trans-sphenoidal resection of the pituitary adenoma, but unfortunately, ischemia was irreversible. Computed tomography (CT) done post-operatively showed hypodensity in the frontal and parietal parasagittal areas, which was also persistent in the follow up CT scans. The patient's neurological function remained poor, with GCS of 8/15, in vegetative state. CONCLUSIONS Vascular complications of the pituitary apoplexy, although uncommon, can be very severe and life threatening. Early detection of vascular compromise caused by hemorrhagic pituitary macroadenoma can prevent delay in intervention. Clinicians should also consider pituitary adenoma as a possible cause of stroke. PMID- 27708254 TI - [Data Analysis of Subacute Patients with Registered Information in the Minimum Basic Data Set for Social-Healthcare (CMBD-RSS), Spain]. AB - OBJECTIVE: It is necessary to deepen in the knowledge of the Basic Minimum Set of Data (CMBD-RSS) of patients with chronic pathology associated and frequent hospitalisations (the subacute care). The aim of this study was to analyse the sanitary information of these patients, once initiated the subacute program. METHODS: We used data of 660 patients hospitalised in the subacute care unit at the Santa Caterina Hospital, sanitary region of Girona, from October 2013 to December 2014. The CMBD data base was analysed using SPSS Statistics 15.0. We verified the relationship between variables i.e. length of stay and age; origin of the patient admission and length of stay (Mann-Whitney U Test); main diagnosis and length of stay (Kruskal-Wallis). We also studied the relationship between origin of the patient admission and main diagnosis (Chi-square test and Cramer's V). RESULTS: The average age of patients was 83 years old, and mainly female profile (55%). Five illnesses concentrated 80% of all patients' diagnosed diseases (mental health problems, nervous system diseases, circulatory problems, respiratory system problems and genitourinary infections). Patients admitted from hospitals had a shorter length of stay (8 days) than patients admitted from home (9 days). 80% of cases patients come back home after the hospital discharge. CONCLUSIONS: People with chronic pathology associated and frequent hospitalisations are an important group of risk. Elderly and clinical decompensations add complexity to these cases. The evaluation of these patients at the admission and discharge procedures optimise the use of the resources. PMID- 27708255 TI - Spiral magnetic order and pressure-induced superconductivity in transition metal compounds. AB - Magnetic and superconducting ground states can compete, cooperate and coexist. MnP provides a compelling and potentially generalizable example of a material where superconductivity and magnetism may be intertwined. Using a synchrotron based non-resonant X-ray magnetic diffraction technique, we reveal a spiral spin order in MnP and trace its pressure evolution towards superconducting order via measurements in a diamond anvil cell. Judging from the magnetostriction, ordered moments vanish at the quantum phase transition as pressure increases the electron kinetic energy. Spins remain local in the disordered phase, and the promotion of superconductivity is likely to emerge from an enhanced coupling to residual spiral spin fluctuations and their concomitant suppression of phonon-mediated superconductivity. As the pitch of the spiral order varies across the 3d transition metal compounds in the MnP family, the magnetic ground state switches between antiferromagnet and ferromagnet, providing an additional tuning parameter in probing spin-fluctuation-induced superconductivity. PMID- 27708257 TI - Crystal structures of the human elongation factor eEFSec suggest a non-canonical mechanism for selenocysteine incorporation. AB - Selenocysteine is the only proteinogenic amino acid encoded by a recoded in-frame UGA codon that does not operate as the canonical opal stop codon. A specialized translation elongation factor, eEFSec in eukaryotes and SelB in prokaryotes, promotes selenocysteine incorporation into selenoproteins by a still poorly understood mechanism. Our structural and biochemical results reveal that four domains of human eEFSec fold into a chalice-like structure that has similar binding affinities for GDP, GTP and other guanine nucleotides. Surprisingly, unlike in eEF1A and EF-Tu, the guanine nucleotide exchange does not cause a major conformational change in domain 1 of eEFSec, but instead induces a swing of domain 4. We propose that eEFSec employs a non-canonical mechanism involving the distinct C-terminal domain 4 for the release of the selenocysteinyl-tRNA during decoding on the ribosome. PMID- 27708259 TI - Efficient and selective N-alkylation of amines with alcohols catalysed by manganese pincer complexes. AB - Borrowing hydrogen (or hydrogen autotransfer) reactions represent straightforward and sustainable C-N bond-forming processes. In general, precious metal-based catalysts are employed for this effective transformation. In recent years, the use of earth abundant and cheap non-noble metal catalysts for this process attracted considerable attention in the scientific community. Here we show that the selective N-alkylation of amines with alcohols can be catalysed by defined PNP manganese pincer complexes. A variety of substituted anilines are monoalkylated with different (hetero)aromatic and aliphatic alcohols even in the presence of other sensitive reducible functional groups. As a special highlight, we report the chemoselective monomethylation of primary amines using methanol under mild conditions. PMID- 27708258 TI - Modelling proteins' hidden conformations to predict antibiotic resistance. AB - TEM beta-lactamase confers bacteria with resistance to many antibiotics and rapidly evolves activity against new drugs. However, functional changes are not easily explained by differences in crystal structures. We employ Markov state models to identify hidden conformations and explore their role in determining TEM's specificity. We integrate these models with existing drug-design tools to create a new technique, called Boltzmann docking, which better predicts TEM specificity by accounting for conformational heterogeneity. Using our MSMs, we identify hidden states whose populations correlate with activity against cefotaxime. To experimentally detect our predicted hidden states, we use rapid mass spectrometric footprinting and confirm our models' prediction that increased cefotaxime activity correlates with reduced Omega-loop flexibility. Finally, we design novel variants to stabilize the hidden cefotaximase states, and find their populations predict activity against cefotaxime in vitro and in vivo. Therefore, we expect this framework to have numerous applications in drug and protein design. PMID- 27708256 TI - ARD1-mediated Hsp70 acetylation balances stress-induced protein refolding and degradation. AB - Heat shock protein (Hsp)70 is a molecular chaperone that maintains protein homoeostasis during cellular stress through two opposing mechanisms: protein refolding and degradation. However, the mechanisms by which Hsp70 balances these opposing functions under stress conditions remain unknown. Here, we demonstrate that Hsp70 preferentially facilitates protein refolding after stress, gradually switching to protein degradation via a mechanism dependent on ARD1-mediated Hsp70 acetylation. During the early stress response, Hsp70 is immediately acetylated by ARD1 at K77, and the acetylated Hsp70 binds to the co-chaperone Hop to allow protein refolding. Thereafter, Hsp70 is deacetylated and binds to the ubiquitin ligase protein CHIP to complete protein degradation during later stages. This switch is required for the maintenance of protein homoeostasis and ultimately rescues cells from stress-induced cell death in vitro and in vivo. Therefore, ARD1-mediated Hsp70 acetylation is a regulatory mechanism that temporally balances protein refolding/degradation in response to stress. PMID- 27708260 TI - Interplay between evanescence and disorder in deep subwavelength photonic structures. AB - Deep subwavelength features are expected to have minimal impact on wave transport. Here we show that in contrast to this common understanding, disorder can have a dramatic effect in a one-dimensional disordered optical system with spatial features a thousand times smaller than the wavelength. We examine a unique regime of Anderson localization where the localization length is shown to scale linearly with the wavelength instead of diverging, because of the role of evanescent waves. In addition, we demonstrate an unusual order of magnitude enhancement of transmission induced due to localization. These results are described for electromagnetic waves, but are directly relevant to other wave systems such as electrons in multi-quantum-well structures. PMID- 27708263 TI - Unveiling the pentagonal nature of perfectly aligned single-and double-strand Si nano-ribbons on Ag(110). AB - Carbon and silicon pentagonal low-dimensional structures attract a great interest as they may lead to new exotic phenomena such as topologically protected phases or increased spin-orbit effects. However, no pure pentagonal phase has yet been realized for any of them. Here we unveil through extensive density functional theory calculations and scanning tunnelling microscope simulations, confronted to key experimental facts, the hidden pentagonal nature of single- and double-strand chiral Si nano-ribbons perfectly aligned on Ag(110) surfaces whose structure has remained elusive for over a decade. Our study reveals an unprecedented one dimensional Si atomic arrangement solely comprising almost perfect alternating pentagons residing in the missing row troughs of the reconstructed surface. We additionally characterize the precursor structure of the nano-ribbons, which consists of a Si cluster (nano-dot) occupying a silver di-vacancy in a quasi hexagonal configuration. The system thus materializes a paradigmatic shift from a silicene-like packing to a pentagonal one. PMID- 27708262 TI - Evaluation of KIR3DL1/KIR3DS1 polymorphism in Behcet's disease. AB - The Behcet's disease (BD)-associated human leukocyte antigen (HLA) allele, HLA B*51 (B*51), encodes a ligand for a pair of allelic killer immunoglobulin-like receptors (KIR) present on cytotoxic cells-KIR3DL1, which inhibits their cytotoxicity, and KIR3DS1, which activates their cytotoxic activity. We tested whether KIR-regulated mechanisms contribute to BD by testing for association of KIR3DL1/KIR3DS1 genotypes with disease in 1799 BD patients and 1710 healthy controls from Turkey, as well as in different subsets of individuals with HLA type-defined ligands for the KIR3D receptors. HLA types were imputed from single nucleotide polymorphism genotypes determined with the Immunochip. The presence of inhibitory KIR3DL1 or activating KIR3DS1 alleles did not differ significantly between cases and controls (KIR3DL1: 92.9% vs 93.4%, Pdominant=0.55; KIR3DS1: 42.7% vs 41.0%, Pdominant=0.29). The KIR3DL1/KIR3DS1 alleles were also present at similar frequencies among cases and controls bearing HLA-B with a Bw4 motif; HLA B with a Bw4 motif with isoleucine at position 80; and HLA-B*51. Our results suggest that pathogenic mechanisms associated with HLA-B*51 do not primarily involve differential interactions with KIR3DL1 and KIR3DS1 receptors. However, due to the complexity of this locus (that is, sequence variation and copy number variation), we cannot exclude a role for other types of KIR variation in the pathogenesis of BD. PMID- 27708261 TI - Genome sequence of the basal haplorrhine primate Tarsius syrichta reveals unusual insertions. AB - Tarsiers are phylogenetically located between the most basal strepsirrhines and the most derived anthropoid primates. While they share morphological features with both groups, they also possess uncommon primate characteristics, rendering their evolutionary history somewhat obscure. To investigate the molecular basis of such attributes, we present here a new genome assembly of the Philippine tarsier (Tarsius syrichta), and provide extended analyses of the genome and detailed history of transposable element insertion events. We describe the silencing of Alu monomers on the lineage leading to anthropoids, and recognize an unexpected abundance of long terminal repeat-derived and LINE1-mobilized transposed elements (Tarsius interspersed elements; TINEs). For the first time in mammals, we identify a complete mitochondrial genome insertion within the nuclear genome, then reveal tarsier-specific, positive gene selection and posit population size changes over time. The genomic resources and analyses presented here will aid efforts to more fully understand the ancient characteristics of primate genomes. PMID- 27708264 TI - Competitive solvent-molecule interactions govern primary processes of diphenylcarbene in solvent mixtures. AB - Photochemical reactions in solution often proceed via competing reaction pathways comprising intermediates that capture a solvent molecule. A disclosure of the underlying reaction mechanisms is challenging due to the rapid nature of these processes and the intricate identification of how many solvent molecules are involved. Here combining broadband femtosecond transient absorption and quantum mechanics/molecular mechanics simulations, we show for one of the most reactive species, diphenylcarbene, that the decision-maker is not the nearest solvent molecule but its neighbour. The hydrogen bonding dynamics determine which reaction channels are accessible in binary solvent mixtures at room temperature. In-depth analysis of the amount of nascent intermediates corroborates the importance of a hydrogen-bonded complex with a protic solvent molecule, in striking analogy to complexes found at cryogenic temperatures. Our results show that adjacent solvent molecules take the role of key abettors rather than bystanders for the fate of the reactive intermediate. PMID- 27708265 TI - Spatiotemporal control of cell-cell reversible interactions using molecular engineering. AB - Manipulation of cell-cell interactions has potential applications in basic research and cell-based therapy. Herein, using a combination of metabolic glycan labelling and bio-orthogonal click reaction, we engineer cell membranes with beta cyclodextrin and subsequently manipulate cell behaviours via photo-responsive host-guest recognition. With this methodology, we demonstrate reversible manipulation of cell assembly and disassembly. The method enables light controllable reversible assembly of cell-cell adhesion, in contrast with previously reported irreversible effects, in which altered structure could not be reused. We also illustrate the utility of the method by designing a cell-based therapy. Peripheral blood mononuclear cells modified with aptamer are effectively redirected towards target cells, resulting in enhanced cell apoptosis. Our approach allows precise control of reversible cell-cell interactions and we expect that it will promote further developments of cell-based therapy. PMID- 27708266 TI - Mechanism of pH-dependent activation of the sodium-proton antiporter NhaA. AB - Escherichia coli NhaA is a prototype sodium-proton antiporter, which has been extensively characterized by X-ray crystallography, biochemical and biophysical experiments. However, the identities of proton carriers and details of pH regulated mechanism remain controversial. Here we report constant pH molecular dynamics data, which reveal that NhaA activation involves a net charge switch of a pH sensor at the entrance of the cytoplasmic funnel and opening of a hydrophobic gate at the end of the funnel. The latter is triggered by charging of Asp164, the first proton carrier. The second proton carrier Lys300 forms a salt bridge with Asp163 in the inactive state, and releases a proton when a sodium ion binds Asp163. These data reconcile current models and illustrate the power of state-of-the-art molecular dynamics simulations in providing atomic details of proton-coupled transport across membrane which is challenging to elucidate by experimental techniques. PMID- 27708268 TI - A route for a strong increase of critical current in nanostrained iron-based superconductors. AB - The critical temperature Tc and the critical current density Jc determine the limits to large-scale superconductor applications. Superconductivity emerges at Tc. The practical current-carrying capability, measured by Jc, is the ability of defects in superconductors to pin the magnetic vortices, and that may reduce Tc. Simultaneous increase of Tc and Jc in superconductors is desirable but very difficult to realize. Here we demonstrate a route to raise both Tc and Jc together in iron-based superconductors. By using low-energy proton irradiation, we create cascade defects in FeSe0.5Te0.5 films. Tc is enhanced due to the nanoscale compressive strain and proximity effect, whereas Jc is doubled under zero field at 4.2 K through strong vortex pinning by the cascade defects and surrounding nanoscale strain. At 12 K and above 15 T, one order of magnitude of Jc enhancement is achieved in both parallel and perpendicular magnetic fields to the film surface. PMID- 27708269 TI - Tuning the catalytic CO hydrogenation to straight- and long-chain aldehydes/alcohols and olefins/paraffins. AB - The catalytic CO hydrogenation is one of the most versatile large-scale chemical syntheses leading to variable chemical feedstock. While traditionally mainly methanol and long-chain hydrocarbons are produced by CO hydrogenation, here we show that the same reaction can be tuned to produce long-chain n-aldehydes, 1 alcohols and olefins, as well as n-paraffins over potassium-promoted CoMn catalysts. The sum selectivity of aldehydes and alcohols is usually >50 wt% whereof up to ~97% can be n-aldehydes. While the product slate contains ~60% n aldehydes at /pCO=0.5, a 65/35% slate of paraffins/alcohols is obtained at a ratio of 9. A linear Anderson-Schulz-Flory behaviour, independent of the /pCO ratio, is found for the sum of C4+ products. We advocate a synergistic interaction between a Mn5O8 oxide and a bulk Co2C phase, promoted by the presence of potassium, to be responsible for the unique product spectra in our studies. PMID- 27708267 TI - A high-quality human reference panel reveals the complexity and distribution of genomic structural variants. AB - Structural variation (SV) represents a major source of differences between individual human genomes and has been linked to disease phenotypes. However, the majority of studies provide neither a global view of the full spectrum of these variants nor integrate them into reference panels of genetic variation. Here, we analyse whole genome sequencing data of 769 individuals from 250 Dutch families, and provide a haplotype-resolved map of 1.9 million genome variants across 9 different variant classes, including novel forms of complex indels, and retrotransposition-mediated insertions of mobile elements and processed RNAs. A large proportion are previously under reported variants sized between 21 and 100 bp. We detect 4 megabases of novel sequence, encoding 11 new transcripts. Finally, we show 191 known, trait-associated SNPs to be in strong linkage disequilibrium with SVs and demonstrate that our panel facilitates accurate imputation of SVs in unrelated individuals. PMID- 27708270 TI - INPPL1 gene mutations in opsismodysplasia. AB - The INPPL1 (inositol polyphosphate phosphatase-like 1) gene encodes the inositol phosphatase, SHIP2 (for src homology 2 domain-containing inositol phosphatase 2). SHIP2 functions to dephosphorylate, and negatively regulate, the lipid second messenger phosphatidylinositol (3,4,5)P3. SHIP2 has been well studied in the area of insulin resistance and obesity but has roles in cancer and other disorders. Recently, it was reported that mutations in INPPL1 cause opsismodysplasia, a rare, autosomal recessive severe skeletal dysplasia. This review focuses on the mutations associated with opsismodysplasia and explores the role of INPPL1/ SHIP2 in skeletal development. PMID- 27708271 TI - Most Martin-Bell syndrome (FMR1-related disorder) Venezuelan patients did not show CGG expansion but instead display genetic heterogeneity. AB - Martin-Bell syndrome is mainly caused by the expansion of CGG trinucleotide repeats (>200 CGG) in the first exon of the FMR1 gene, leading to hypermethylation of the promoter region and silencing of the FMR1 protein expression. These changes are responsible for a phenotype with varying degrees of mental retardation, a long face with large and protruding ears, macroorchidism and autistic behavior. There may also be, however, patients who exhibit typical features of the syndrome without any expansion in the FMR1 gene; thus, other mechanisms affecting the expression of the FMR1 gene were assessed in 25 out of 29 ascertained patients with the typical phenotype without full mutation. Promoter methylation status of FMR1, mutations in its sequence and copy number variations (CNVs) in genes associated with intellectual disability were investigated. In 25 independent male patients without expansion, the promoter region was unmethylated; one patient with a full mutation showed methylation mosaicism; and a female patient had 81.2% of CpG sites methylated and 18.8% hemimethylated. One heterozygous duplication in exon 6 of the PDCD6 gene (programmed cell death 6) and a heterozygous deletion in exon 5 of the CHL1 gene (cell adhesion molecule L1), respectively, were found in two independent patients. PMID- 27708272 TI - Detection of SHOX gene aberrations in routine diagnostic practice and evaluation of phenotype scoring form effectiveness. AB - Heterozygous aberrations of SHOX gene have been reported to be responsible for Leri-Weill dyschondrosteosis (LWD) and small portion of idiopathic short stature. The study was established to assess effectiveness of using phenotype 'scoring form' in patients indicated for SHOX gene defect analysis. The submitted study is based on a retrospective group of 352 unrelated patients enrolled as a part of the routine diagnostic practice and analyzed for aberrations affecting the SHOX gene. All participants were scanned for deletion/duplication within the main pseudoautosomal region (PAR1) using the multiplex ligation-dependent probe amplification (MLPA) method. The phenotype 'scoring form' is used in our laboratory practice to preselect patients for subsequent mutation analysis of SHOX gene-coding sequences. The overall detection rate was 11.1% but there was a significant increase in frequency of SHOX gene defect positive with increasing achieved score (P<0.0001). The most frequent aberration was a causal deletion within PAR1. In three probands, MLPA analysis indicated a more complex rearrangement. Madelung deformity or co-occurrence of disproportionate short stature, short forearm and muscular hypertrophy had represented the most potent markers to determine the likelihood of SHOX gene defect detection. We conclude that appliance of phenotype 'scoring form' had saved excessive sample analysis and enabled effective routine diagnostic testing. PMID- 27708274 TI - Direct X-ray photoconversion in flexible organic thin film devices operated below 1 V. AB - The application of organic electronic materials for the detection of ionizing radiations is very appealing thanks to their mechanical flexibility, low-cost and simple processing in comparison to their inorganic counterpart. In this work we investigate the direct X-ray photoconversion process in organic thin film photoconductors. The devices are realized by drop casting solution-processed bis (triisopropylsilylethynyl)pentacene (TIPS-pentacene) onto flexible plastic substrates patterned with metal electrodes; they exhibit a strong sensitivity to X-rays despite the low X-ray photon absorption typical of low-Z organic materials. We propose a model, based on the accumulation of photogenerated charges and photoconductive gain, able to describe the magnitude as well as the dynamics of the X-ray-induced photocurrent. This finding allows us to fabricate and test a flexible 2 * 2 pixelated X-ray detector operating at 0.2 V, with gain and sensitivity up to 4.7 * 104 and 77,000 nC mGy-1 cm-3, respectively. PMID- 27708273 TI - The sensitivity of exome sequencing in identifying pathogenic mutations for LGMD in the United States. AB - The current study characterizes a cohort of limb-girdle muscular dystrophy (LGMD) in the United States using whole-exome sequencing. Fifty-five families affected by LGMD were recruited using an institutionally approved protocol. Exome sequencing was performed on probands and selected parental samples. Pathogenic mutations and cosegregation patterns were confirmed by Sanger sequencing. Twenty two families (40%) had novel and previously reported pathogenic mutations, primarily in LGMD genes, and also in genes for Duchenne muscular dystrophy, facioscapulohumeral muscular dystrophy, congenital myopathy, myofibrillar myopathy, inclusion body myopathy and Pompe disease. One family was diagnosed via clinical testing. Dominant mutations were identified in COL6A1, COL6A3, FLNC, LMNA, RYR1, SMCHD1 and VCP, recessive mutations in ANO5, CAPN3, GAA, LAMA2, SGCA and SGCG, and X-linked mutations in DMD. A previously reported variant in DMD was confirmed to be benign. Exome sequencing is a powerful diagnostic tool for LGMD. Despite careful phenotypic screening, pathogenic mutations were found in other muscle disease genes, largely accounting for the increased sensitivity of exome sequencing. Our experience suggests that broad sequencing panels are useful for these analyses because of the phenotypic overlap of many neuromuscular conditions. The confirmation of a benign DMD variant illustrates the potential of exome sequencing to help determine pathogenicity. PMID- 27708275 TI - A modular platform for one-step assembly of multi-component membrane systems by fusion of charged proteoliposomes. AB - An important goal in synthetic biology is the assembly of biomimetic cell-like structures, which combine multiple biological components in synthetic lipid vesicles. A key limiting assembly step is the incorporation of membrane proteins into the lipid bilayer of the vesicles. Here we present a simple method for delivery of membrane proteins into a lipid bilayer within 5 min. Fusogenic proteoliposomes, containing charged lipids and membrane proteins, fuse with oppositely charged bilayers, with no requirement for detergent or fusion promoting proteins, and deliver large, fragile membrane protein complexes into the target bilayers. We demonstrate the feasibility of our method by assembling a minimal electron transport chain capable of adenosine triphosphate (ATP) synthesis, combining Escherichia coli F1Fo ATP-synthase and the primary proton pump bo3-oxidase, into synthetic lipid vesicles with sizes ranging from 100 nm to ~10 MUm. This provides a platform for the combination of multiple sets of membrane protein complexes into cell-like artificial structures. PMID- 27708277 TI - Diabetes: Cardiovascular benefits of semaglutide. PMID- 27708276 TI - A distinct holoenzyme organization for two-subunit pyruvate carboxylase. AB - Pyruvate carboxylase (PC) has important roles in metabolism and is crucial for virulence for some pathogenic bacteria. PC contains biotin carboxylase (BC), carboxyltransferase (CT) and biotin carboxyl carrier protein (BCCP) components. It is a single-chain enzyme in eukaryotes and most bacteria, and functions as a 500 kD homo-tetramer. In contrast, PC is a two-subunit enzyme in a collection of Gram-negative bacteria, with the alpha subunit containing the BC and the beta subunit the CT and BCCP domains, and it is believed that the holoenzyme has alpha4beta4 stoichiometry. We report here the crystal structures of a two-subunit PC from Methylobacillus flagellatus. Surprisingly, our structures reveal an alpha2beta4 stoichiometry, and the overall architecture of the holoenzyme is strikingly different from that of the homo-tetrameric PCs. Biochemical and mutagenesis studies confirm the stoichiometry and other structural observations. Our functional studies in Pseudomonas aeruginosa show that its two-subunit PC is important for colony morphogenesis.

AB - Heart failure with reduced ejection fraction (HFrEF) develops when cardiac output falls as a result of cardiac injury. The most well-recognized of the compensatory homeostatic responses to a fall in cardiac output are activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS). In the short term, these 'neurohormonal' systems induce a number of changes in the heart, kidneys, and vasculature that are designed to maintain cardiovascular homeostasis. However, with chronic activation, these responses result in haemodynamic stress and exert deleterious effects on the heart and the circulation. Neurohormonal activation is now known to be one of the most important mechanisms underlying the progression of heart failure, and therapeutic antagonism of neurohormonal systems has become the cornerstone of contemporary pharmacotherapy for heart failure. In this Review, we discuss the effects of neurohormonal activation in HFrEF and highlight the mechanisms by which these systems contribute to disease progression. PMID- 27708282 TI - Sensing the quantum limit in scanning tunnelling spectroscopy. AB - The tunnelling current in scanning tunnelling spectroscopy (STS) is typically and often implicitly modelled by a continuous and homogeneous charge flow. If the charging energy of a single-charge quantum sufficiently exceeds the thermal energy, however, the granularity of the current becomes non-negligible. In this quantum limit, the capacitance of the tunnel junction mediates an interaction of the tunnelling electrons with the surrounding electromagnetic environment and becomes a source of noise itself, which cannot be neglected in STS. Using a scanning tunnelling microscope operating at 15 mK, we show that we operate in this quantum limit, which determines the ultimate energy resolution in STS. The P(E)-theory describes the probability for a tunnelling electron to exchange energy with the environment and can be regarded as the energy resolution function.

AB - For clinicians grappling with quantifying the complex spatial and temporal patterns of cardiac structure and function (such as myocardial trabeculae, coronary microvascular anatomy, tissue perfusion, myocyte histology, electrical conduction, heart rate, and blood-pressure variability), fractal analysis is a powerful, but still underused, mathematical tool. In this Perspectives article, we explain some fundamental principles of fractal geometry and place it in a familiar medical setting. We summarize studies in the cardiovascular sciences in which fractal methods have successfully been used to investigate disease mechanisms, and suggest potential future clinical roles in cardiac imaging and time series measurements. We believe that clinical researchers can deploy innovative fractal solutions to common cardiac problems that might ultimately translate into advancements for patient care. PMID- 27708284 TI - Blood pressure differences between office and home settings among Japanese normotensive subjects and hypertensive patients. AB - This study attempted to clarify the differences in blood pressure (BP) between the office (clinic) and home settings in patients with controlled, sustained, masked or white-coat hypertension. The following formula was used: office mean systolic BP (omSBP)-mean morning home SBP (mmhSBP)/office mean diastolic BP (omDBP)-mean morning home DBP (mmhDBP). The paired t-test was used for statistical analysis. The omSBP-mmhSBP/omDBP-mmhDBP calculation yielded the following results: among normotensive subjects, -1.1+/-11.2/-1.7+/-8.5 mm Hg (mean SBP and mean DBP were higher at home than in the office; n=451, P=0.038 in SBP, P=0.000 in DBP); in controlled hypertensive patients, -0.42+/-10.9/-2.2+/ 8.2 mm Hg (n=1362, P=0.160 in SBP, P=0.000 in DBP); among sustained hypertensive patients, 5.6+/-14.7/0.048+/-9.9 mm Hg (n=1370, P=0.000 in SBP, P=0.857 in DBP); in masked hypertensive patients, -15.3+/-12.9/-9.3+/-9.5 mm Hg (n=1308, both P=0.000); and among white-coat hypertensive patients, 23.7+/-13.2/8.2+/-9.1 mm Hg (n=580, both P=0.000). Our results showed a difference of 5 mm Hg in SBP among sustained hypertensive patients, as recommended by the Japanese Society of Hypertension Guidelines for the Management of Hypertension; however, in other hypertensive patient types, the differences in SBP and DBP between office and home measurements differed by >5 mm Hg. Office and home BP measurements should be interpreted cautiously, keeping in mind the clinical setting.

AB - Obesity is associated with an increased risk of developing breast cancer and is also associated with worse clinical prognosis. The mechanistic link between obesity and breast cancer progression remains unclear, and there has been no development of specific treatments to improve the outcome of obese cancer patients. Here we show that obesity-associated NLRC4 inflammasome activation/ interleukin (IL)-1 signalling promotes breast cancer progression. The tumour microenvironment in the context of obesity induces an increase in tumour infiltrating myeloid cells with an activated NLRC4 inflammasome that in turn activates IL-1beta, which drives disease progression through adipocyte-mediated vascular endothelial growth factor A (VEGFA) expression and angiogenesis. Further studies show that treatment of mice with metformin inhibits obesity-associated tumour progression associated with a marked decrease in angiogenesis. This report provides a causal mechanism by which obesity promotes breast cancer progression and lays out a foundation to block NLRC4 inflammasome activation or IL-1beta signalling transduction that may be useful for the treatment of obese cancer patients.

AB - The spontaneous assembly of chemically encoded, molecularly crowded, water-rich micro-droplets into periodic defect-free two-dimensional arrays is achieved in aqueous media by a combination of an acoustic standing wave pressure field and in situ complex coacervation. Acoustically mediated coalescence of primary droplets generates single-droplet per node micro-arrays that exhibit variable surface attachment properties, spontaneously uptake dyes, enzymes and particles, and display spatial and time-dependent fluorescence outputs when exposed to a reactant diffusion gradient. In addition, coacervate droplet arrays exhibiting dynamical behaviour and exchange of matter are prepared by inhibiting coalescence to produce acoustically trapped lattices of droplet clusters that display fast and reversible changes in shape and spatial configuration in direct response to modulations in the acoustic frequencies and fields. Our results offer a novel route to the design and construction of 'water-in-water' micro-droplet arrays with controllable spatial organization, programmable signalling pathways and higher order collective behaviour. PMID- 27708285 TI - Evolutionary trajectories of snake genes and genomes revealed by comparative analyses of five-pacer viper. AB - Snakes have numerous features distinctive from other tetrapods and a rich history of genome evolution that is still obscure. Here, we report the high-quality genome of the five-pacer viper, Deinagkistrodon acutus, and comparative analyses with other representative snake and lizard genomes. We map the evolutionary trajectories of transposable elements (TEs), developmental genes and sex chromosomes onto the snake phylogeny. TEs exhibit dynamic lineage-specific expansion, and many viper TEs show brain-specific gene expression along with their nearby genes. We detect signatures of adaptive evolution in olfactory, venom and thermal-sensing genes and also functional degeneration of genes associated with vision and hearing. Lineage-specific relaxation of functional constraints on respective Hox and Tbx limb-patterning genes supports fossil evidence for a successive loss of forelimbs then hindlimbs during snake evolution. Finally, we infer that the ZW sex chromosome pair had undergone at least three recombination suppression events in the ancestor of advanced snakes. These results altogether forge a framework for our deep understanding into snakes' history of molecular evolution. PMID- 27708290 TI - Cardiovascular biology: 'Good' fat may cut heart disease. PMID- 27708291 TI - Upward revision of global fossil fuel methane emissions based on isotope database. AB - Methane has the second-largest global radiative forcing impact of anthropogenic greenhouse gases after carbon dioxide, but our understanding of the global atmospheric methane budget is incomplete. The global fossil fuel industry (production and usage of natural gas, oil and coal) is thought to contribute 15 to 22 per cent of methane emissions to the total atmospheric methane budget. However, questions remain regarding methane emission trends as a result of fossil fuel industrial activity and the contribution to total methane emissions of sources from the fossil fuel industry and from natural geological seepage, which are often co-located. Here we re-evaluate the global methane budget and the contribution of the fossil fuel industry to methane emissions based on long-term global methane and methane carbon isotope records. We compile the largest isotopic methane source signature database so far, including fossil fuel, microbial and biomass-burning methane emission sources. We find that total fossil fuel methane emissions (fossil fuel industry plus natural geological seepage) are not increasing over time, but are 60 to 110 per cent greater than current estimates owing to large revisions in isotope source signatures. We show that this is consistent with the observed global latitudinal methane gradient. After accounting for natural geological methane seepage, we find that methane emissions from natural gas, oil and coal production and their usage are 20 to 60 per cent greater than inventories. Our findings imply a greater potential for the fossil fuel industry to mitigate anthropogenic climate forcing, but we also find that methane emissions from natural gas as a fraction of production have declined from approximately 8 per cent to approximately 2 per cent over the past three decades.

AB - Lower olefins-generally referring to ethylene, propylene and butylene-are basic carbon-based building blocks that are widely used in the chemical industry, and are traditionally produced through thermal or catalytic cracking of a range of hydrocarbon feedstocks, such as naphtha, gas oil, condensates and light alkanes. With the rapid depletion of the limited petroleum reserves that serve as the source of these hydrocarbons, there is an urgent need for processes that can produce lower olefins from alternative feedstocks. The 'Fischer-Tropsch to olefins' (FTO) process has long offered a way of producing lower olefins directly from syngas-a mixture of hydrogen and carbon monoxide that is readily derived from coal, biomass and natural gas. But the hydrocarbons obtained with the FTO process typically follow the so-called Anderson-Schulz-Flory distribution, which is characterized by a maximum C2-C4 hydrocarbon fraction of about 56.7 per cent and an undesired methane fraction of about 29.2 per cent (refs 1, 10, 11, 12). Here we show that, under mild reaction conditions, cobalt carbide quadrangular nanoprisms catalyse the FTO conversion of syngas with high selectivity for the production of lower olefins (constituting around 60.8 per cent of the carbon products), while generating little methane (about 5.0 per cent), with the ratio of desired unsaturated hydrocarbons to less valuable saturated hydrocarbons amongst the C2-C4 products being as high as 30. Detailed catalyst characterization during the initial reaction stage and theoretical calculations indicate that preferentially exposed {101} and {020} facets play a pivotal role during syngas conversion, in that they favour olefin production and inhibit methane formation, and thereby render cobalt carbide nanoprisms a promising new catalyst system for directly converting syngas into lower olefins.

Understanding the brain mechanisms controlling sleep requires the identification of key neurons in the control circuits and mapping of their synaptic connections. Technical innovations over the past decade have greatly facilitated dissection of the sleep circuits. This has set the stage for understanding how a variety of environmental and physiological factors influence sleep. The ability to initiate and terminate sleep on command will also help us to elucidate its functions within and beyond the brain. PMID- 27708316 TI - Corporate culture has no place in academia.

PMID- 27708333 TI - Differential hepatic distribution of insulin receptor substrates causes selective insulin resistance in diabetes and obesity. AB - Hepatic insulin signalling involves insulin receptor substrates (Irs) 1/2, and is normally associated with the inhibition of gluconeogenesis and activation of lipogenesis. In diabetes and obesity, insulin no longer suppresses hepatic gluconeogenesis, while continuing to activate lipogenesis, a state referred to as 'selective insulin resistance'. Here, we show that 'selective insulin resistance' is caused by the differential expression of Irs1 and Irs2 in different zones of the liver. We demonstrate that hepatic Irs2-knockout mice develop 'selective insulin resistance', whereas mice lacking in Irs1, or both Irs1 and Irs2, develop 'total insulin resistance'. In obese diabetic mice, Irs1/2-mediated insulin signalling is impaired in the periportal zone, which is the primary site of gluconeogenesis, but enhanced in the perivenous zone, which is the primary site of lipogenesis. While hyperinsulinaemia reduces Irs2 expression in both the periportal and perivenous zones, Irs1 expression, which is predominantly in the perivenous zone, remains mostly unaffected. These data suggest that 'selective insulin resistance' is induced by the differential distribution, and alterations of hepatic Irs1 and Irs2 expression. PMID- 27708334 TI - Loss of immune tolerance to IL-2 in type 1 diabetes. AB - Type 1 diabetes (T1D) is characterized by a chronic, progressive autoimmune attack against pancreas-specific antigens, effecting the destruction of insulin producing beta-cells. Here we show interleukin-2 (IL-2) is a non-pancreatic autoimmune target in T1D. Anti-IL-2 autoantibodies, as well as T cells specific for a single orthologous epitope of IL-2, are present in the peripheral blood of non-obese diabetic (NOD) mice and patients with T1D. In NOD mice, the generation of anti-IL-2 autoantibodies is genetically determined and their titre increases with age and disease onset. In T1D patients, circulating IgG memory B cells specific for IL-2 or insulin are present at similar frequencies. Anti-IL-2 autoantibodies cloned from T1D patients demonstrate clonality, a high degree of somatic hypermutation and nanomolar affinities, indicating a germinal centre origin and underscoring the synergy between cognate autoreactive T and B cells leading to defective immune tolerance. PMID- 27708336 TI - Metal-free photochemical silylations and transfer hydrogenations of benzenoid hydrocarbons and graphene. AB - The first hydrogenation step of benzene, which is endergonic in the electronic ground state (S0), becomes exergonic in the first triplet state (T1). This is in line with Baird's rule, which tells that benzene is antiaromatic and destabilized in its T1 state and also in its first singlet excited state (S1), opposite to S0, where it is aromatic and remarkably unreactive. Here we utilized this feature to show that benzene and several polycyclic aromatic hydrocarbons (PAHs) to various extents undergo metal-free photochemical (hydro)silylations and transfer hydrogenations at mild conditions, with the highest yield for naphthalene (photosilylation: 21%). Quantum chemical computations reveal that T1-state benzene is excellent at H-atom abstraction, while cyclooctatetraene, aromatic in the T1 and S1 states according to Baird's rule, is unreactive. Remarkably, also CVD-graphene on SiO2 is efficiently transfer-photohydrogenated using formic acid/water mixtures together with white light or solar irradiation under metal free conditions. PMID- 27708337 TI - Sorting cells by their dynamical properties. AB - Recent advances in cell sorting aim at the development of novel methods that are sensitive to various mechanical properties of cells. Microfluidic technologies have a great potential for cell sorting; however, the design of many micro devices is based on theories developed for rigid spherical particles with size as a separation parameter. Clearly, most bioparticles are non-spherical and deformable and therefore exhibit a much more intricate behavior in fluid flow than rigid spheres. Here, we demonstrate the use of cells' mechanical and dynamical properties as biomarkers for separation by employing a combination of mesoscale hydrodynamic simulations and microfluidic experiments. The dynamic behavior of red blood cells (RBCs) within deterministic lateral displacement (DLD) devices is investigated for different device geometries and viscosity contrasts between the intra-cellular fluid and suspending medium. We find that the viscosity contrast and associated cell dynamics clearly determine the RBC trajectory through a DLD device. Simulation results compare well to experiments and provide new insights into the physical mechanisms which govern the sorting of non-spherical and deformable cells in DLD devices. Finally, we discuss the implications of cell dynamics for sorting schemes based on properties other than cell size, such as mechanics and morphology.

AB - Misfolded alpha-synuclein (AS) and other neurodegenerative disorder proteins display prion-like transmission of protein aggregation. Factors responsible for the initiation of AS aggregation are unknown. To evaluate the role of amyloid proteins made by the microbiota we exposed aged rats and transgenic C. elegans to E. coli producing the extracellular bacterial amyloid protein curli. Rats exposed to curli-producing bacteria displayed increased neuronal AS deposition in both gut and brain and enhanced microgliosis and astrogliosis compared to rats exposed to either mutant bacteria unable to synthesize curli, or to vehicle alone. Animals exposed to curli producing bacteria also had more expression of TLR2, IL 6 and TNF in the brain than the other two groups. There were no differences among the rat groups in survival, body weight, inflammation in the mouth, retina, kidneys or gut epithelia, and circulating cytokine levels. AS-expressing C. elegans fed on curli-producing bacteria also had enhanced AS aggregation. These results suggest that bacterial amyloid functions as a trigger to initiate AS aggregation through cross-seeding and also primes responses of the innate immune system.

AB - The enhancement of boiling heat transfer, the most powerful energy-transferring technology, will lead to milestones in the development of high-efficiency, next generation energy systems. Perceiving nano-inspired interface functionalities from their rough morphologies, we demonstrate interface-induced liquid refreshing is essential to improve heat transfer by intrinsically avoiding Leidenfrost phenomenon. High liquid accessibility of hemi-wicking and catalytic nucleation, triggered by the morphological and hydrodynamic peculiarities of nano-inspired interfaces, contribute to the critical heat flux (CHF) and the heat transfer coefficient (HTC). Our experiments show CHF is a function of universal hydrodynamic characteristics involving interfacial liquid accessibility and HTC is improved with a higher probability of smaller nuclei with less superheat. Considering the interface-induced and bulk liquid accessibility at boiling, we discuss functionalizing the interactivity between an interface and a counteracting fluid seeking to create a novel interface, a so-called smart interface, for a breakthrough in boiling and its pragmatic application in energy systems. PMID- 27708340 TI - Activation and increase of radio-sensitive CD11b+ recruited Kupffer cells/macrophages in diet-induced steatohepatitis in FGF5 deficient mice. AB - We have recently reported that Kupffer cells consist of two subsets, radio resistant resident CD68+ Kupffer cells and radio-sensitive recruited CD11b+ Kupffer cells/macrophages (Mphis). Non-alcoholic steatohepatitis (NASH) is characterized not only by hepatic steatosis but also chronic inflammation and fibrosis. In the present study, we investigated the immunological mechanism of diet-induced steatohepatitis in fibroblast growth factor 5 (FGF5) deficient mice. After consumption of a high fat diet (HFD) for 8 weeks, FGF5 null mice developed severe steatohepatitis and fibrosis resembling human NASH. F4/80+ Mphis which were both CD11b and CD68 positive accumulated in the liver. The production of TNF and FasL indicated that they are the pivotal effectors in this hepatitis. The weak phagocytic activity and lack of CRIg mRNA suggested that they were recruited Mphis. Intermittent exposure to 1 Gy irradiation markedly decreased these Mphis and dramatically inhibited liver inflammation without attenuating steatosis. However, depletion of the resident subset by clodronate liposome (c-lipo) treatment increased the Mphis and tended to exacerbate disease progression. Recruited CD11b+ CD68+ Kupffer cells/Mphis may play an essential role in steatohepatitis and fibrosis in FGF5 null mice fed with a HFD. Recruitment and activation of bone marrow derived Mphis is the key factor to develop steatohepatitis from simple steatosis. PMID- 27708342 TI - Nonlinear backbone torsional pair correlations in proteins. AB - Protein allostery requires dynamical structural correlations. Physical origin of which, however, remain elusive despite intensive studies during last two and half decades. Based on analysis of molecular dynamics (MD) simulation trajectories for ten proteins with different sizes and folds, we found that nonlinear backbone torsional pair (BTP) correlations, which are mainly spatially long-ranged and are dominantly executed by loop residues, exist extensively in most analyzed proteins. Examination of torsional motion for correlated BTPs suggested that such nonlinear correlations are mainly associated aharmonic torsional state transitions and in some cases strongly anisotropic local torsional motion of participating torsions, and occur on widely different and relatively longer time scales. In contrast, correlations between backbone torsions in stable alpha helices and beta strands are mainly linear and spatially short-ranged, and are more likely to associate with harmonic local torsional motion. Further analysis revealed that the direct cause of nonlinear contributions are heterogeneous linear correlations. These findings implicate a general search strategy for novel allosteric modulation sites of protein activities. PMID- 27708343 TI - Biodiversity loss and turnover in alternative states in the Mediterranean Sea: a case study on meiofauna. AB - In the Mediterranean Sea hard-bottom macroalgal meadows may switch to alternative and less-productive barrens grounds, as a result of sea urchins overgrazing. Meiofauna (and especially nematodes) represent key components of benthic ecosystems, are highly-diversified, sensitive to environmental change and anthropogenic impacts, but, so-far, have been neglected in studies on regime shifts. We report here that sedimentary organic matter contents, meiofaunal taxa richness and community composition, nematode alpha- and beta-biodiversity vary significantly between alternative macroalgal and barren states. The observed differences are consistent in six areas spread across the Mediterranean Sea, irrespective of barren extent. Our results suggest also that the low biodiversity levels in barren states are the result of habitat loss/fragmentation, which is associated also with a lower availability of trophic resources. Furthermore, differences in meiofaunal and nematode abundance, biomass and diversity between macroalgal meadow and barren states persist when the latter is not fully formed, or consists of patches interspersed in macroalgal meadows. Since barren grounds are expanding rapidly along the Mediterranean Sea and meiofauna are a key trophic component in marine ecosystems, we suggest that the extension and persistence of barrens at the expenses of macroalgal meadows could also affect resilience of higher trophic level. PMID- 27708344 TI - Illusions of having small or large invisible bodies influence visual perception of object size. AB - The size of our body influences the perceived size of the world so that objects appear larger to children than to adults. The mechanisms underlying this effect remain unclear. It has been difficult to dissociate visual rescaling of the external environment based on an individual's visible body from visual rescaling based on a central multisensory body representation. To differentiate these potential causal mechanisms, we manipulated body representation without a visible body by taking advantage of recent developments in body representation research. Participants experienced the illusion of having a small or large invisible body while object-size perception was tested. Our findings show that the perceived size of test-objects was determined by the size of the invisible body (inverse relation), and by the strength of the invisible body illusion. These findings demonstrate how central body representation directly influences visual size perception, without the need for a visible body, by rescaling the spatial representation of the environment. PMID- 27708345 TI - Characterization of maize roothairless6 which encodes a D-type cellulose synthase and controls the switch from bulge formation to tip growth. AB - Root hairs are tubular extensions of the epidermis. Root hairs of the monogenic recessive maize mutant roothairless 6 (rth6) are arrested after bulge formation during the transition to tip growth and display a rough cell surface. BSR-Seq in combination with Seq-walking and subsequent analyses of four independently generated mutant alleles established that rth6 encodes CSLD5 a plasma membrane localized 129 kD D-type cellulose synthase with eight transmembrane domains. Cellulose synthases are required for the biosynthesis of cellulose, the most abundant biopolymer of plant cell walls. Phylogenetic analyses revealed that RTH6 is part of a monocot specific clade of D-type cellulose synthases. D-type cellulose synthases are highly conserved in the plant kingdom with five gene family members in maize and homologs even among early land plants such as the moss Physcomitrella patens or the clubmoss Selaginella moellendorffii. Expression profiling demonstrated that rth6 transcripts are highly enriched in root hairs as compared to all other root tissues. Moreover, in addition to the strong knock down of rth6 expression in young primary roots of the mutant rth6, the gene is also significantly down-regulated in rth3 and rth5 mutants, while it is up regulated in rth2 mutants, suggesting that these genes interact in cell wall biosynthesis. PMID- 27708346 TI - Role of areca nut induced JNK/ATF2/Jun axis in the activation of TGF-beta pathway in precancerous Oral Submucous Fibrosis. AB - Oral submucous fibrosis (OSF) is potentially premalignant with progressive and irreversible extracellular matrix deposition accompanied by epithelial atrophy and like other fibrotic disorders, is primarily a TGF-beta driven disease. OSF is caused by prolonged chewing of areca nut. Our previous studies reported a pivotal role for TGF-beta activation and its effects contributing to OSF. However, the mechanism for activation of TGF-beta signaling in OSF is still unknown. In this study we demonstrate activation of TGF-beta signaling with sub-cytotoxic dose of areca nut in epithelial cells and discovered a key role for pJNK in this process. In good correlation; pJNK was detected in OSF tissues but not in normal tissues. Moreover, activation of JNK was found to be dependent on muscarinic acid receptor induced Ca2+/CAMKII as well as ROS. JNK dependent phosphorylation of ATF2/c-Jun transcription factors resulted in TGF-beta transcription and its signaling. pATF2/p-c-Jun were enriched on TGF-beta promoter and co-localized in nuclei of epithelial cells upon areca nut treatment. In corroboration, OSF tissue sections also had nuclear pATF2 and p-c-Jun. Our results provide comprehensive mechanistic details of TGF-beta signaling induced by etiological agent areca nut in the manifestation of fibrosis which can lead to new therapeutic modalities for OSF. PMID- 27708347 TI - Humic acid inhibits HBV-induced autophagosome formation and induces apoptosis in HBV-transfected Hep G2 cells. AB - Hepatitis B Virus (HBV) utilizes several mechanisms to survive in the host cells and one of the main pathways being autophagosome formation. Humic acid (HA), one of the major components of Mineral pitch, is an Ayurvedic medicinal food, commonly used by the people of the Himalayan regions of Nepal and India for various body ailments. We hypothesized that HA could induce cell death and inhibit HBV-induced autophagy in hepatic cells. Incubation of Hep G2.2.1.5 cells (HepG2 cells stably expressing HBV) with HA (100 MUM) inhibited both cell proliferation and autophagosome formation significantly, while apoptosis induction was enhanced. Western blot results showed that HA incubation resulted in decreased levels of beclin-1, SIRT-1 and c-myc, while caspase-3 and beta catenin expression were up-regulated. Western blot results showed that HA significantly inhibited the expression of HBx (3-fold with 50 MUM and 5-fold with 100 MUM) compared to control cells. When HA was incubated with HBx-transfected Hep G2 cells, HBx-induced autophagosome formation and beclin-1 levels were decreased. These data showed that HA induced apoptosis and inhibited HBV-induced autophagosome formation and proliferation in hepatoma cells. PMID- 27708348 TI - A chimeric protein-based malaria vaccine candidate induces robust T cell responses against Plasmodium vivax MSP119. AB - The most widespread Plasmodium species, Plasmodium vivax, poses a significant public health threat. An effective vaccine is needed to reduce global malaria burden. Of the erythrocytic stage vaccine candidates, the 19 kDa fragment of the P. vivax Merozoite Surface Protein 1 (PvMSP119) is one of the most promising. Our group has previously defined several promiscuous T helper epitopes within the PvMSP1 protein, with features that allow them to bind multiple MHC class II alleles. We describe here a P. vivax recombinant modular chimera based on MSP1 (PvRMC-MSP1) that includes defined T cell epitopes genetically fused to PvMSP119. This vaccine candidate preserved structural elements of the native PvMSP119 and elicited cytophilic antibody responses, and CD4+ and CD8+ T cells capable of recognizing PvMSP119. Although CD8+ T cells that recognize blood stage antigens have been reported to control blood infection, CD8+ T cell responses induced by P. falciparum or P. vivax vaccine candidates based on MSP119 have not been reported. To our knowledge, this is the first time a protein based subunit vaccine has been able to induce CD8+ T cell against PvMSP119. The PvRMC-MSP1 protein was also recognized by naturally acquired antibodies from individuals living in malaria endemic areas with an antibody profile associated with protection from infection. These features make PvRMC-MSP1 a promising vaccine candidate. PMID- 27708351 TI - Spatial and Structural Metrics for Living Cells Inspired by Statistical Mechanics. AB - Experimental observations in cell biology have advanced to a stage where theory could play a larger role, much as it has done in the physical sciences. Possibly the lack of a common framework within which experimentalists, computational scientists and theorists could equally contribute has hindered this development, for the worse of both disciplines. Here we demonstrate the usage of tools and concepts from statistical mechanics to describe processes inside living cells based on experimental data, suggesting that future theoretical/computational models may be based on such concepts. To illustrate the ideas, we describe the organisation of subcellular structures within the cell in terms of (density) pair correlation functions, and subsequently use the same concepts to follow nano sized objects being transported inside the cell. Finally, we quantify an interesting subcellular re-organisation, not previously discerned by molecular biology methods. PMID- 27708350 TI - Beatquency domain and machine learning improve prediction of cardiovascular death after acute coronary syndrome. AB - Frequency domain measures of heart rate variability (HRV) are associated with adverse events after a myocardial infarction. However, patterns in the traditional frequency domain (measured in Hz, or cycles per second) may capture different cardiac phenomena at different heart rates. An alternative is to consider frequency with respect to heartbeats, or beatquency. We compared the use of frequency and beatquency domains to predict patient risk after an acute coronary syndrome. We then determined whether machine learning could further improve the predictive performance. We first evaluated the use of pre-defined frequency and beatquency bands in a clinical trial dataset (N = 2302) for the HRV risk measure LF/HF (the ratio of low frequency to high frequency power). Relative to frequency, beatquency improved the ability of LF/HF to predict cardiovascular death within one year (Area Under the Curve, or AUC, of 0.730 vs. 0.704, p < 0.001). Next, we used machine learning to learn frequency and beatquency bands with optimal predictive power, which further improved the AUC for beatquency to 0.753 (p < 0.001), but not for frequency. Results in additional validation datasets (N = 2255 and N = 765) were similar. Our results suggest that beatquency and machine learning provide valuable tools in physiological studies of HRV. PMID- 27708349 TI - Improved Cryopreservation of Human Umbilical Vein Endothelial Cells: A Systematic Approach. AB - Cryopreservation of human umbilical vein endothelial cells (HUVECs) facilitated their commercial availability for use in vascular biology, tissue engineering and drug delivery research; however, the key variables in HUVEC cryopreservation have not been comprehensively studied. HUVECs are typically cryopreserved by cooling at 1 degrees C/min in the presence of 10% dimethyl sulfoxide (DMSO). We applied interrupted slow cooling (graded freezing) and interrupted rapid cooling with a hold time (two-step freezing) to identify where in the cooling process cryoinjury to HUVECs occurs. We found that linear cooling at 1 degrees C/min resulted in higher membrane integrities than linear cooling at 0.2 degrees C/min or nonlinear two-step freezing. DMSO addition procedures and compositions were also investigated. By combining hydroxyethyl starch with DMSO, HUVEC viability after cryopreservation was improved compared to measured viabilities of commercially available cryopreserved HUVECs and viabilities for HUVEC cryopreservation studies reported in the literature. Furthermore, HUVECs cryopreserved using our improved procedure showed high tube forming capability in a post-thaw angiogenesis assay, a standard indicator of endothelial cell function. As well as presenting superior cryopreservation procedures for HUVECs, the methods developed here can serve as a model to optimize the cryopreservation of other cells.

AB - Purified water supply for human use, agriculture and industry is the major global priority nowadays. The advanced oxidation process based on atmospheric pressure non-thermal plasma (NTP) has been used for purification of wastewater, although the underlying mechanisms of degradation of organic pollutants are still unknown. In this study we employ two needle-type atmospheric pressure non-thermal plasma jets, i.e., indirect (ID-APPJ) and direct (D-APPJ) jets operating at Ar feed gas, for the treatment of methylene blue, methyl orange and congo red dyes, for two different times (i.e., 20 min and 30 min). Specifically, we study the decolorization/degradation of all three dyes using the above mentioned plasma sources, by means of UV-Vis spectroscopy, HPLC and a density meter. We also employ mass spectroscopy to verify whether only decolorization or also degradation takes place after treatment of the dyes by the NTP jets. Additionally, we analyze the interaction of OH radicals with all three dyes using reactive molecular dynamics simulations, based on the density functional-tight binding method. This investigation represents the first report on the degradation of these three different dyes by two types of NTP setups, analyzed by various methods, and based on both experimental and computational studies.

AB - Human ADP-ribosyltransferase 2 (ARTD2/PARP2) is an enzyme catalyzing a post translational modification, ADP-ribosylation. It is one of the three DNA dependent ARTDs in the 17 member enzyme family. ADP-ribosylation catalyzed by ARTD2 is involved in the regulation of multiple cellular processes such as control of chromatin remodeling, transcription and DNA repair. Here we used a combination of biochemical and biophysical methods to elucidate the structure and function of ARTD2. The solution structures revealed the binding mode of the ARTD2 monomer and dimer to oligonucleotides that mimic damaged DNA. In the complex, DNA binds between the WGR domain and the catalytic fragment. The binding mode is supported by biophysical data that indicate all domains contribute to DNA binding. Also, our study showed that ARTD2 is preferentially activated by short 5'-phosphorylated DNA oligonucleotides. We demonstrate that the N-terminus functions as a high-affinity DNA-binding module, while the WGR domain contributes to DNA binding specificity and subsequent catalytic activation. Our data further suggest that ARTD2 would function in double strand break repair as a dimeric module, while in single strand break repair it would function as a monomer. PMID- 27708354 TI - Plasticity mechanisms in HfN at elevated and room temperature. AB - HfN specimens deformed via four-point bend tests at room temperature and at 2300 degrees C (~0.7 Tm) showed increased plasticity response with temperature. Dynamic diffraction via transmission electron microscopy (TEM) revealed ?110?{111} as the primary slip system in both temperature regimes and ?110?{110} to be a secondary slip system activated at elevated temperature. Dislocation line lengths changed from a primarily linear to a curved morphology with increasing temperature suggestive of increased dislocation mobility being responsible for the brittle to ductile temperature transition. First principle generalized stacking fault energy calculations revealed an intrinsic stacking fault (ISF) along ?112?{111}, which is the partial dislocation direction for slip on these close packed planes. Though B1 structures, such as NaCl and HfC predominately slip on ?110?{110}, the ISF here is believed to facilitate slip on the {111} planes for this B1 HfN phase. PMID- 27708355 TI - Activation of Xer-recombination at dif: structural basis of the FtsKgamma-XerD interaction. AB - Bacterial chromosomes are most often circular DNA molecules. This can produce a topological problem; a genetic crossover from homologous recombination results in dimerization of the chromosome. A chromosome dimer is lethal unless resolved. A site-specific recombination system catalyses this dimer-resolution reaction at the chromosomal site dif. In Escherichia coli, two tyrosine-family recombinases, XerC and XerD, bind to dif and carry out two pairs of sequential strand exchange reactions. However, what makes the reaction unique among site-specific recombination reactions is that the first step, XerD-mediated strand exchange, relies on interaction with the very C-terminus of the FtsK DNA translocase. FtsK is a powerful molecular motor that functions in cell division, co-ordinating division with clearing chromosomal DNA from the site of septation and also acts to position the dif sites for recombination. This is a model system for unlinking, separating and segregating large DNA molecules. Here we describe the molecular detail of the interaction between XerD and FtsK that leads to activation of recombination as deduced from a co-crystal structure, biochemical and in vivo experiments. FtsKgamma interacts with the C-terminal domain of XerD, above a cleft where XerC is thought to bind. We present a model for activation of recombination based on structural data. PMID- 27708356 TI - Spatial genome organization and cognition. AB - Nonrandom chromosomal conformations, including promoter-enhancer loopings that bypass kilobases or megabases of linear genome, provide a crucial layer of transcriptional regulation and move vast amounts of non-coding sequence into the physical proximity of genes that are important for neurodevelopment, cognition and behaviour. Activity-regulated changes in the neuronal '3D genome' could govern transcriptional mechanisms associated with learning and plasticity, and loop-bound intergenic and intronic non-coding sequences have been implicated in psychiatric and adult-onset neurodegenerative disease. Recent studies have begun to clarify the roles of spatial genome organization in normal and abnormal cognition. PMID- 27708357 TI - Identification of TLR2/TLR6 signalling lactic acid bacteria for supporting immune regulation. AB - Although many lactic acid bacteria (LAB) influence the consumer's immune status it is not completely understood how this is established. Bacteria-host interactions between bacterial cell-wall components and toll-like receptors (TLRs) have been suggested to play an essential role. Here we investigated the interaction between LABs with reported health effects and TLRs. By using cell lines expressing single or combination of TLRs, we show that LABs can signal via TLR-dependent and independent pathways. The strains only stimulated and did not inhibit TLRs. We found that several strains such as L. plantarum CCFM634, L. plantarum CCFM734, L. fermentum CCFM381, L. acidophilus CCFM137, and S. thermophilus CCFM218 stimulated TLR2/TLR6. TLR2/TLR6 is essential in immune regulatory processes and of interest for prevention of diseases. Specificity of the TLR2/TLR6 stimulation was confirmed with blocking antibodies. Immunomodulatory properties of LABs were also studied by assessing IL-10 and IL-6 secretion patterns in bacteria-stimulated THP1-derived macrophages, which confirmed species and strain specific effects of the LABs. With this study we provide novel insight in LAB specific host-microbe interactions. Our data demonstrates that interactions between pattern recognition receptors such as TLRs is species and strain specific and underpins the importance of selecting specific strains for promoting specific health effects. PMID- 27708358 TI - Increased Duodenal Eosinophil Degranulation in Patients with Functional Dyspepsia: A Prospective Study. AB - Functional dyspepsia (FD) is a functional gastrointestinal disorder diagnosed by symptom-based criteria. It has been said that duodenal immune activation plays a role in the pathogenesis of FD. The primary aims of the study were to compare the total number of duodenal eosinophil and evaluate the eosinophil degranulation rate, number of duodenal degranulated eosinophil and mast cell between patients with FD and healthy subjects. We enrolled 96 patients with FD and 24 healthy controls at Sir Run Run Shaw Hospital. The total number of eosinophil was comparable in the second portion of duodenum (D2) and duodenal bulb (D1) between patients with FD and healthy controls (all P > 0.05). Significant higher eosinophil degranulation positive rate in D2 (P = 0.003) and a trend towards higher in D1 (P = 0.084) were observed in patients with FD compared with healthy controls. Moreover, the number of duodenal degranulated eosinophil in patients with FD were significantly increased than healthy controls in D1(9.8 +/- 6.3 vs 2.9 +/- 2.1 per HPF, P = 0.0002) and a trend towards increase in D2 (10.7 +/- 7.7 vs 5.3 +/- 0.9 per HPF, P = 0.077), respectively. However, degranulated mast cells in patients with FD were almost same with healthy controls. Increased eosinophils degranulation in duodenum play an important role in pathogenesis of FD. PMID- 27708359 TI - Monolithic-Structured Single-Layered Textile-Based Dye-Sensitized Solar Cells. AB - Textile-structured solar cells are frequently discussed in the literature due to their prospective applications in wearable devices and in building integrated solar cells that utilize their flexibility, mechanical robustness, and aesthetic appearance, but the current approaches for textile-based solar cells-including the preparation of fibre-type solar cells woven into textiles-face several difficulties from high friction and tension during the weaving process. This study proposes a new structural concept and fabrication process for monolithic structured textile-based dye-sensitized solar cells that are fabricated by a process similar to the cloth-making process, including the preparation of wires and yarns that are woven for use in textiles, printed, dyed, and packaged. The fabricated single-layered textile-based dye-sensitized solar cells successfully act as solar cells in our study, even under bending conditions. By controlling the inter-weft spacing and the number of Ti wires for the photoelectrode conductor, we have found that the performance of this type of dye-sensitized solar cell was notably affected by the spacing between photoelectrodes and counter-electrodes, the exposed areas of Ti wires to photoelectrodes, and photoelectrodes' surface morphology. We believe that this study provides a process and concept for improved textile-based solar cells that can form the basis for further research. PMID- 27708360 TI - Grain Boundary Specific Segregation in Nanocrystalline Fe(Cr). AB - A cross-correlative precession electron diffraction - atom probe tomography investigation of Cr segregation in a Fe(Cr) nanocrystalline alloy was undertaken. Solute segregation was found to be dependent on grain boundary type. The results of which were compared to a hybrid Molecular Dynamics and Monte Carlo simulation that predicted the segregation for special character, low angle, and high angle grain boundaries, as well as the angle of inclination of the grain boundary. It was found that the highest segregation concentration was for the high angle grain boundaries and is explained in terms of clustering driven by the onset of phase separation. For special character boundaries, the highest Gibbsain interfacial excess was predicted at the incoherent ?3 followed by ?9 and ?11 boundaries with negligible segregation to the twin and ?5 boundaries. In addition, the low angle grain boundaries predicted negligible segregation. All of these trends matched well with the experiment. This solute-boundary segregation dependency for the special character grain boundaries is explained in terms of excess volume and the energetic distribution of the solute in the boundary. PMID- 27708361 TI - Infant-specific gaze patterns in response to radial optic flow. AB - The focus of a radial optic flow is a valid visual cue used to perceive and control the heading direction of animals. Gaze patterns in response to the focus of radial optic flow were measured in human infants (N = 100, 4-18 months) and in adults (N = 20) using an eye-tracking technique. Overall, although the adults showed an advantage in detecting the focus of an expansion flow (representing forward locomotion) against that of a contraction flow (representing backward locomotion), infants younger than 1 year showed an advantage in detecting the focus of a contraction flow. Infants aged between 13 and 18 months showed no significant advantage in detecting the focus in either the expansion or in the contraction flow. The uniqueness of the gaze patterns in response to the focus of radial optic flow in infants shows that the visual information necessary to perceive heading direction potentially differs between younger and mature individuals. PMID- 27708362 TI - Cystathionine gamma-lyase is expressed in human atherosclerotic plaque microvessels and is involved in micro-angiogenesis. AB - Atherosclerotic plaques are classically divided into stable and vulnerable plaques. Vulnerable plaques are prone to rupture with a risk for infarction. High intraplaque microvessel density predisposes to plaque vulnerability. Hydrogen sulfide (H2S) is a proangiogenic gasotransmitter which is endogenously produced by cystathionine gamma-lyase (CSE), and is believed to have vasculoprotective effects. However, due to its proangiogenic effects, H2S may result in pathological angiogenesis in atherosclerotic plaques, thereby increasing plaque vulnerability. The aim of this study was to determine CSE expression pattern in atherosclerotic plaques, and investigate whether CSE is involved in micro angiogenesis in vitro. Endarterectomy plaques were studied for CSE expression, and the role of CSE in micro-angiogenesis was studied in vitro. CSE is expressed in plaques with similar levels in both stable and vulnerable plaques. CSE co localized with von Willebrand Factor-positive microvessel endothelial cells and alpha-smooth-muscle actin-positive SMCs. In vitro, inhibition of CSE in HMEC-1 reduced tube formation, cell viability/proliferation, and migration which was restored after culture in the presence of H2S donor GYY4137. CSE is expressed in intraplaque microvessels, and H2S is a stimulator of micro-angiogenesis in vitro. Due to this pro-angiogenic effect, high levels of CSE in atherosclerotic plaques may be a potential risk for plaque vulnerability. PMID- 27708364 TI - Orthotropic Piezoelectricity in 2D Nanocellulose. AB - The control of electromechanical responses within bonding regions is essential to face frontier challenges in nanotechnologies, such as molecular electronics and biotechnology. Here, we present Ibeta-nanocellulose as a potentially new orthotropic 2D piezoelectric crystal. The predicted in-layer piezoelectricity is originated on a sui-generis hydrogen bonds pattern. Upon this fact and by using a combination of ab-initio and ad-hoc models, we introduce a description of electrical profiles along chemical bonds. Such developments lead to obtain a rationale for modelling the extended piezoelectric effect originated within bond scales. The order of magnitude estimated for the 2D Ibeta-nanocellulose piezoelectric response, ~pm V-1, ranks this material at the level of currently used piezoelectric energy generators and new artificial 2D designs. Such finding would be crucial for developing alternative materials to drive emerging nanotechnologies. PMID- 27708363 TI - An rs4705342 T>C polymorphism in the promoter of miR-143/145 is associated with a decreased risk of ischemic stroke. AB - The expression of miR-143/miR-145 was up-regulated in ischemic stroke (IS), which may be used as biomarkers and/or therapeutic targets for IS. We aimed to investigate the association of rs4705342 and rs4705343 polymorphisms in the promoter of miR-143/145 with risk of IS. The study population comprised 445 patients with IS and 518 controls. The rs4705342 genotype was analyzed by using a TaqMan Assay and the rs4705343 genotype was determined by using a polymerase chain reaction-restriction fragment length polymorphism assay. Relative expression of miR-143/miR-145 was measured by quantitative real-time PCR. We found that the rs4705342 was associated with a decreased risk of IS (TC vs. TT: adjusted OR = 0.74, 95% CI, 0.57-0.97; CC vs. TT: adjusted OR = 0.53, 95% CI, 0.34-0.83). Haplotype analysis showed that the TC haplotype was associated with an increased risk of IS risk (OR = 1.33, 95% CI, 1.01-1.75), whereas the CT haplotype was associated with a decreased risk of IS risk (OR = 0.68, 95% CI, 0.50-0.92). Importantly, patients carrying the rs4705342TC/CC genotypes had a lower level of miR-145 (P = 0.03). We found for the first time that the rs4705342 CC was a protective factor for IS, probably by reducing the level of miR-145. PMID- 27708365 TI - Chimpanzees can visually perceive differences in the freshness of foods. AB - Colour vision in primates is believed to be an adaptation for finding ripe fruit and young leaves. The contribution of the luminance distribution, which influences how humans evaluate the freshness of food, has not been explored with respect to the detection of subtle distinctions in food quality in non-human primates. We examined how chimpanzees, which are closely related to humans, perceive the freshness of foods. The findings suggest that chimpanzees were able to choose fresher cabbage based on both colour and grey-scale images. Additional tests with images of novel cabbage, spinach, and strawberries revealed that one chimpanzee could detect the freshness of other fruits and vegetables. The critical factor in determining the judgements of freshness made by the chimpanzees was the spatial layout of luminance information. These findings provide the first known evidence that chimpanzees discriminate between images representing various degrees of freshness based solely on luminance information. PMID- 27708366 TI - Biotransformation of ferulic acid to vanillin in the packed bed-stirred fermentors. AB - We performed the biotransformation of ferulic acid to vanillin using Bacillus subtilis (B. subtilis) in the stirring packed-bed reactors filled with carbon fiber textiles (CFT). Scanning electron microscope (SEM), HPLC, qRT-PCR and ATP assay indicated that vanillin biotransformation is tightly related to cell growth, cellar activity and the extent of biofilm formation. The biotransformation was affected by hydraulic retention time (HRT), temperature, initial pH, stirring speed and ferulic acid concentration, and the maximum vanillin production was obtained at 20 h, 35 degrees C, 9.0, 200 rpm, 1.5 g/L, respectively. Repeated batch biotransformation performed under this optimized condition showed that the maximum productivity (0.047 g/L/h) and molar yield (60.43%) achieved in immobilized cell system were 1.84 and 3.61 folds higher than those achieved in free cell system. Therefore, the stirring reactor packed with CFT carrier biofilm formed by B. subtilis represented a valid biocatalytic system for the production of vanillin. PMID- 27708367 TI - P[8] and P[4] Rotavirus Infection Associated with Secretor Phenotypes Among Children in South China. AB - Rotaviruses are known to recognize human histo-blood group antigens (HBGAs) as a host ligand that is believed to play an important role in rotavirus host susceptibility and host range. In this study, paired fecal and saliva samples collected from children with viral gastroenteritis, as well as paired serum and saliva samples collected from the general population in south China were studied to evaluate potential association between rotavirus infections and human HBGA phenotypes. Rotavirus was detected in 75 (28%) of 266 fecal samples and P[8] rotaviruses were found to be the predominant genotype. The HBGA phenotypes of the rotavirus-infected children were determined through their saliva samples. Secretor statuses were found to correlate with the risk of rotavirus infection and all P[8]/P[4] rotavirus infected children were secretors. Accordingly, recombinant VP8* proteins of the P[8]/P[4] rotaviruses bound saliva samples from secretor individuals. Furthermore, correlation between serum P[8]/P[4]-specific IgG and host Lewis and secretor phenotypes has been found among 206 studied serum samples. Our study supported the association between rotavirus infection and the host HBGA phenotypes, which would help further understanding of rotavirus host range and epidemiology. PMID- 27708368 TI - Evaluation of A Novel Split-Feeding Anaerobic/Oxic Baffled Reactor (A/OBR) For Foodwaste Anaerobic Digestate: Performance, Modeling and Bacterial Community. AB - To enhance the treatment efficiency from an anaerobic digester, a novel six compartment anaerobic/oxic baffled reactor (A/OBR) was employed. Two kinds of split-feeding A/OBRs R2 and R3, with influent fed in the 1st, 3rd and 5th compartment of the reactor simultaneously at the respective ratios of 6:3:1 and 6:2:2, were compared with the regular-feeding reactor R1 when all influent was fed in the 1st compartment (control). Three aspects, the COD removal, the hydraulic characteristics and the bacterial community, were systematically investigated, compared and evaluated. The results indicated that R2 and R3 had similar tolerance to loading shock, but the R2 had the highest COD removal of 91.6% with a final effluent of 345 mg/L. The mixing patterns in both split feeding reactors were intermediate between plug-flow and completely-mixed, with dead spaces between 8.17% and 8.35% compared with a 31.9% dead space in R1. Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis revealed that the split-feeding strategy provided a higher bacterial diversity and more stable bacterial community than that in the regular-feeding strategy. Further analysis indicated that Firmicutes, Bacteroidetes, and Proteobacteria were the dominant bacteria, among which Firmicutes and Bacteroidetes might be responsible for organic matter degradation and Proteobacteria for nitrification and denitrification. PMID- 27708369 TI - Increasing The Genetic Admixture of Available Lines of Human Pluripotent Stem Cells. AB - Human pluripotent stem cells (hPSCs) may significantly improve drug development pipeline, serving as an in vitro system for the identification of novel leads, and for testing drug toxicity. Furthermore, these cells may be used to address the issue of differential drug response, a phenomenon greatly influenced by genetic factors. This application depends on the availability of hPSC lines from populations with diverse ancestries. So far, it has been reported that most lines of hPSCs derived worldwide are of European or East Asian ancestries. We have established 23 lines of hPSCs from Brazilian individuals, and we report the analysis of their genomic ancestry. We show that embryo-derived PSCs are mostly of European descent, while induced PSCs derived from participants of a national wide Brazilian cohort study present high levels of admixed European, African and Native American genomic ancestry. Additionally, we use high density SNP data and estimate local ancestries, particularly those of CYP genes loci. Such information will be of key importance when interpreting variation among cell lines with respect to cellular phenotypes of interest. The availability of genetically admixed lines of hPSCs will be of relevance when setting up future in vitro studies of drug response. PMID- 27708370 TI - Structure-based discovery of potentially active semiochemicals for Cydia pomonella (L.). AB - The development of physiologically active semiochemicals is largely limited by the labor-consuming searching process. How to screen active semiochemicals efficiently is of significance to the extension of behavior regulation in pest control. Here pharmacophore modeling and shape-based virtual screening were combined to predict candidate ligands for Cydia pomonella pheromone binding protein 1 (CpomPBP1). Out of the predicted compounds, ETrME displayed the highest affinity to CpomPBP1. Further studies on the interaction between CpomPBP1 and ETrME, not only depicted the binding mode, but also revealed residues providing negative and positive contributions to the ETrME binding. Moreover, key residues involved in interacting with ETrME of CpomPBP1 were determined as well. These findings were significant to providing insights for the future searching and optimization of active semiochemicals. PMID- 27708372 TI - Design and fabrication of high-performance diamond triple-gate field-effect transistors. AB - The lack of large-area single-crystal diamond wafers has led us to downscale diamond electronic devices. Here, we design and fabricate a hydrogenated diamond (H-diamond) triple-gate metal-oxide-semiconductor field-effect transistor (MOSFET) to extend device downscaling and increase device output current. The device's electrical properties are compared with those of planar-type MOSFETs, which are fabricated simultaneously on the same substrate. The triple-gate MOSFET's output current (174.2 mA mm-1) is much higher than that of the planar type device (45.2 mA mm-1), and the on/off ratio and subthreshold swing are more than 108 and as low as 110 mV dec-1, respectively. The fabrication of these H diamond triple-gate MOSFETs will drive diamond electronic device development forward towards practical applications. PMID- 27708371 TI - The Important Role of Halogen Bond in Substrate Selectivity of Enzymatic Catalysis. AB - The use of halogen bond is widespread in drug discovery, design, and clinical trials, but is overlooked in drug biosynthesis. Here, the role of halogen bond in the nitrilase-catalyzed synthesis of ortho-, meta-, and para-chlorophenylacetic acid was investigated. Different distributions of halogen bond induced changes of substrate binding conformation and affected substrate selectivity. By engineering the halogen interaction, the substrate selectivity of the enzyme changed, with the implication that halogen bond plays an important role in biosynthesis and should be used as an efficient and reliable tool in enzymatic drug synthesis. PMID- 27708373 TI - GlycoMinestruct: a new bioinformatics tool for highly accurate mapping of the human N-linked and O-linked glycoproteomes by incorporating structural features. AB - Glycosylation plays an important role in cell-cell adhesion, ligand-binding and subcellular recognition. Current approaches for predicting protein glycosylation are primarily based on sequence-derived features, while little work has been done to systematically assess the importance of structural features to glycosylation prediction. Here, we propose a novel bioinformatics method called GlycoMinestruct(http://glycomine.erc.monash.edu/Lab/GlycoMine_Struct/) for improved prediction of human N- and O-linked glycosylation sites by combining sequence and structural features in an integrated computational framework with a two-step feature-selection strategy. Experiments indicated that GlycoMinestruct outperformed NGlycPred, the only predictor that incorporated both sequence and structure features, achieving AUC values of 0.941 and 0.922 for N- and O-linked glycosylation, respectively, on an independent test dataset. We applied GlycoMinestruct to screen the human structural proteome and obtained high confidence predictions for N- and O-linked glycosylation sites. GlycoMinestruct can be used as a powerful tool to expedite the discovery of glycosylation events and substrates to facilitate hypothesis-driven experimental studies. PMID- 27708375 TI - The detection accuracy of cone beam CT for osseous defects of the temporomandibular joint: a systematic review and meta-analysis. AB - The purpose of this review was to evaluate whether cone-beam computed tomography (CBCT) is reliable for the detection of bone changes of the temporomandibular joint (TMJ). Studies collected from the PubMed, Web of Science, Cochrane Library, ScienceDirect, Embase, Wanfang and CNKI databases were searched, and the publishing time was limited from January 1990 to December 2015. Eight studies (23 experimental research groups) were eventually included for further analysis. The pooled sensitivity was 0.67 and the pooled specificity was 0.87, which leads to a relatively large area (0.84) under the Receiver Operating Characteristic (ROC) curve. The related pooled positive likelihood ratio (+LR) and the pooled negative likelihood ratio (-LR) were 5.2 and 0.38, respectively. The subgroup analysis was conducted for four subgroups categorized by voxel size (<=0.2; >0.2, <=0.3; >0.3, <=0.4; >0.4, and <=0.5 (mm)), and the ">0.4, <=0.5" subgroup had a higher pooled sensitivity and pooled specificity than the other groups. The present study demonstrates that CBCT has a relatively high diagnostic accuracy for TMJ bone changes, although its reliability is limited. Voxel size did not play a role in the accuracy of CBCT. PMID- 27708374 TI - A transgenic approach to control hemipteran insects by expressing insecticidal genes under phloem-specific promoters. AB - The first generation transgenic crops used strong constitutive promoters for transgene expression. However, tissue-specific expression is desirable for more precise targeting of transgenes. Moreover, piercing/sucking insects, which are generally resistant to insecticidal Bacillus thuringiensis (Bt) proteins, have emerged as a major pests since the introduction of transgenic crops expressing these toxins. Phloem-specific promoters isolated from Banana bunchy top virus (BBTV) were used for the expression of two insecticidal proteins, Hadronyche versuta (Blue Mountains funnel-web spider) neurotoxin (Hvt) and onion leaf lectin, in tobacco (Nicotiana tabacum). Here we demonstrate that transgenic plants expressing Hvt alone or in combination with onion leaf lectin are resistant to Phenacoccus solenopsis (cotton mealybug), Myzus persicae (green peach aphids) and Bemisia tabaci (silver leaf whitefly). The expression of both proteins under different phloem-specific promoters resulted in close to 100% mortality and provided more rapid protection than Hvt alone. Our results suggest the employment of the Hvt and onion leaf lectin transgenic constructs at the commercial level will reduce the use of chemical pesticides for control of hemipteran insect pests. PMID- 27708376 TI - Clinical associations of IL-10 and IL-37 in systemic lupus erythematosus. AB - Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by the development of autoantibodies to nuclear antigens and inflammatory responses mediated by multiple cytokines. Although previous studies have determined clinical associations between SLE and the anti-inflammatory cytokines IL-10 and IL-37, their role in the disease, or their potential as biomarkers, remains unclear. We examined serum levels of IL-10 and IL-37 in a large cohort of SLE patients, with detailed longitudinal clinical data. We demonstrate a statistically significant association of serum IL-10 with disease activity, with higher levels in active compared to inactive disease. High first visit IL-10 was predictive of high subsequent disease activity; patients with IL-10 in highest quartile at first visit were 3.6 times more likely to have active disease in subsequent visits. Serum IL-37 was also higher in SLE patients compared to control, and was strongly associated with Asian ethnicity. However, IL-37 was not statistically significantly associated with disease activity. IL-37 was significantly reduced in patients with organ damage but this association was attenuated in multivariable analysis. The data suggest that IL-10, but not IL-37, may have potential as a biomarker predictive for disease activity in SLE. PMID- 27708377 TI - Postoperative hormonal therapy prevents recovery of neurological damage after surgery in patients with breast cancer. AB - Cancer survivors are exposed to several risk factors for cognitive dysfunction, such as general anesthesia, surgical trauma, and adjuvant therapies. In our recent study we showed that thalamic volume reduction and attentional dysfunction occurred shortly after surgery. Here, we examined the 6-month prognosis of the 20 patients with breast cancer who underwent surgery. Seven patients did not receive any adjuvant therapy after the surgery and 13 patients received a hormonal therapy after the surgery. We assessed their attentional functions, and thalamic volumes shortly after and 6 months after surgery. We found a significant group x time interaction in the attentional functions (p = 0.033) and the right thalamus (p < 0.05, small volume correction), suggesting the thalamic volume reduction and attentional dysfunction recovered in patients without adjuvant therapy. Our findings provide a better understanding of the potential role of hormonal therapy in relation to the cognitive dysfunction of cancer survivors. PMID- 27708378 TI - Electrochemical noise and impedance of Au electrode/electrolyte interfaces enabling extracellular detection of glioma cell populations. AB - Microelectrode arrays (MEA) record extracellular local field potentials of cells adhered to the electrodes. A disadvantage is the limited signal-to-noise ratio. The state-of-the-art background noise level is about 10 MUVpp. Furthermore, in MEAs low frequency events are filtered out. Here, we quantitatively analyze Au electrode/electrolyte interfaces with impedance spectroscopy and noise measurements. The equivalent circuit is the charge transfer resistance in parallel with a constant phase element that describes the double layer capacitance, in series with a spreading resistance. This equivalent circuit leads to a Maxwell-Wagner relaxation frequency, the value of which is determined as a function of electrode area and molarity of an aqueous KCl electrolyte solution. The electrochemical voltage and current noise is measured as a function of electrode area and frequency and follow unambiguously from the measured impedance. By using large area electrodes the noise floor can be as low as 0.3 MUVpp. The resulting high sensitivity is demonstrated by the extracellular detection of C6 glioma cell populations. Their minute electrical activity can be clearly detected at a frequency below about 10 Hz, which shows that the methodology can be used to monitor slow cooperative biological signals in cell populations.

AB - Optical-resolution photoacoustic microscopy (OR-PAM), a promising microscopic imaging technique with high ultrasound resolution and superior optical sensitivity, can provide anatomical, functional, and molecular information at scales ranging from the microvasculature to single red blood cells. In particular, real-time OR-PAM imaging with a high signal-to-noise ratio (SNR) is a prerequisite for widespread use in preclinical and clinical applications. Although several technical approaches have been pursued to simultaneously improve the imaging speed and SNR of OR-PAM, they are bulky, complex, not sensitive, and/or not actually real-time. In this paper, we demonstrate a simple and novel OR-PAM technique which is based on a typical galvanometer immersed in non conducting liquid. Using an opto-ultrasound combiner, this OR-PAM system achieves a high SNR and fast imaging speed. It takes only 2 seconds to acquire a volumetric image with a wide field of view (FOV) of 4 * 8 mm2 along the X and Y axes, respectively. The measured lateral and axial resolutions are 6.0 and 37.7 MUm, respectively. Finally, as a demonstration of the system's capability, we successfully imaged the microvasculature in a mouse ear in vivo. Our new method will contribute substantially to the popularization and commercialization of OR PAM in various preclinical and clinical applications.

AB - We present experimental demonstrations of two-photon interference involving temporally separated photons within two types of interferometers: a Mach-Zehnder interferometer and a polarization-based Michelson interferometer. The two-photon states are probabilistically prepared in a symmetrically superposed state within the two interferometer arms by introducing a large time delay between two input photons; this state is composed of two temporally separated photons, which are in two different or the same spatial modes. We then observe two-photon interference fringes involving both the Hong-Ou-Mandel interference effect and the interference of path-entangled two-photon states simultaneously in a single interferometric setup. The observed two-photon interference fringes provide simultaneous observation of the interferometric properties of the single-photon and two-photon wavepackets. The observations can also facilitate a more comprehensive understanding of the origins of the interference phenomena arising from spatially bunched/anti-bunched two-photon states comprised of two temporally separated photons within the interferometer arms.

AB - Epilepsy can be regarded as a network phenomenon with functionally and/or structurally aberrant connections in the brain. Over the past years, concepts and methods from network theory substantially contributed to improve the characterization of structure and function of these epileptic networks and thus to advance understanding of the dynamical disease epilepsy. We extend this promising line of research and assess-with high spatial and temporal resolution and using complementary analysis approaches that capture different characteristics of the complex dynamics-both strength and direction of interactions in evolving large-scale epileptic brain networks of 35 patients that suffered from drug-resistant focal seizures with different anatomical onset locations. Despite this heterogeneity, we find that even during the seizure-free interval the seizure onset zone is a brain region that, when averaged over time, exerts strongest directed influences over other brain regions being part of a large-scale network. This crucial role, however, manifested by averaging on the population-sample level only - in more than one third of patients, strongest directed interactions can be observed between brain regions far off the seizure onset zone. This may guide new developments for individualized diagnosis, treatment and control. PMID- 27708382 TI - Temperature controls organic carbon sequestration in a subarctic lake. AB - Widespread ecological reorganizations and increases in organic carbon (OC) in lakes across the Northern Hemisphere have raised concerns about the impact of the ongoing climate warming on aquatic ecosystems and carbon cycling. We employed diverse biogeochemical techniques on a high-resolution sediment record from a subarctic lake in northern Finland (70 degrees N) to examine the direction, magnitude and mechanism of change in aquatic carbon pools prior to and under the anthropogenic warming. Coupled variation in the elemental and isotopic composition of the sediment and a proxy-based summer air temperature reconstruction tracked changes in aquatic production, depicting a decline during a cool climate interval between ~1700-1900 C.E. and a subsequent increase over the 20th century. OC accumulation rates displayed similar coeval variation with temperature, mirroring both changes in aquatic production and terrestrial carbon export. Increase in sediment organic content over the 20th century together with high inferred aquatic UV exposure imply that the 20th century increase in OC accumulation is primarily connected to elevated lake production rather than terrestrial inputs. The changes in the supply of autochthonous energy sources were further reflected higher up the benthic food web, as evidenced by biotic stable isotopic fingerprints. PMID- 27708383 TI - Evidence for nuclear interaction of a cytoskeleton protein (OsIFL) with metallothionein and its role in salinity stress tolerance. AB - Soil salinity is being perceived as a major threat to agriculture. Plant breeders and molecular biologist are putting their best efforts to raise salt-tolerant crops. The discovery of the Saltol QTL, a major QTL localized on chromosome I, responsible for salt tolerance at seedling stage in rice has given new hopes for raising salinity tolerant rice genotypes. In the present study, we have functionally characterized a Saltol QTL localized cytoskeletal protein, intermediate filament like protein (OsIFL), of rice. Studies related to intermediate filaments are emerging in plants, especially with respect to their involvement in abiotic stress response. Our investigations clearly establish that the heterologous expression of OsIFL in three diverse organisms (bacteria, yeast and tobacco) provides survival advantage towards diverse abiotic stresses. Screening of rice cDNA library revealed OsIFL to be strongly interacting with metallothionein protein. Bimolecular fluorescence complementation assay further confirmed this interaction to be occurring inside the nucleus. Overexpression of OsIFL in transgenic tobacco plants conferred salinity stress tolerance by maintaining favourable K+/Na+ ratio and thus showed protection from salinity stress induced ion toxicity. This study provides the first evidence for the involvement of a cytoskeletal protein in salinity stress tolerance in diverse organisms. PMID- 27708384 TI - Aptamer-conjugated live human immune cell based biosensors for the accurate detection of C-reactive protein. AB - C-reactive protein (CRP) is a pentameric protein that is present in the bloodstream during inflammatory events, e.g., liver failure, leukemia, and/or bacterial infection. The level of CRP indicates the progress and prognosis of certain diseases; it is therefore necessary to measure CRP levels in the blood accurately. The normal concentration of CRP is reported to be 1-3 mg/L. Inflammatory events increase the level of CRP by up to 500 times; accordingly, CRP is a biomarker of acute inflammatory disease. In this study, we demonstrated the preparation of DNA aptamer-conjugated peripheral blood mononuclear cells (Apt PBMCs) that specifically capture human CRP. Live PBMCs functionalized with aptamers could detect different levels of human CRP by producing immune complexes with reporter antibody. The binding behavior of Apt-PBMCs toward highly concentrated CRP sites was also investigated. The immune responses of Apt-PBMCs were evaluated by measuring TNF-alpha secretion after stimulating the PBMCs with lipopolysaccharides. In summary, engineered Apt-PBMCs have potential applications as live cell based biosensors and for in vitro tracing of CRP secretion sites. PMID- 27708386 TI - Low viscosity and high attenuation in MgSiO3 post-perovskite inferred from atomic scale calculations. AB - This work represents a numerical study of the thermal activation for dislocation glide of the [100](010) slip system in MgSiO3 post-perovskite (Mg-ppv) at 120 GPa. We propose an approach based on a one-dimensional line tension model in conjunction with atomic-scale calculations. In this model, the key parameters, namely, the line tension and the Peierls barrier, are obtained from density functional theory calculations. We find a Peierls stress sigmap = 2.1 GPa and a line tension Gamma = 9.2 eV/A, which lead to a kink-pair enthalpy (under zero stress) of 2.69 eV. These values confirm that this slip system bears a very low lattice friction because it vanishes for temperatures above approximately 500 K under mantle conditions. In the Earth's mantle, high-pressure Mg-ppv silicate is thus expected to become as ductile as ferropericlase. These results confirm the hypothesis of a weak layer in the D" layer where Mg-ppv is present. Easy glide along [100](010) suggests strong preferred orientations with (010) planes aligned. Highly mobile [100] dislocations are also likely to respond to stresses related to seismic waves, leading to energy dissipation and strong attenuation. PMID- 27708385 TI - Bst1 is required for Candida albicans infecting host via facilitating cell wall anchorage of Glycosylphosphatidyl inositol anchored proteins. AB - Glycosylphosphatidyl inositol anchored proteins (GPI-APs) on fungal cell wall are essential for invasive infections. While the function of inositol deacylation of GPI-APs in mammalian cells has been previously characterized the impact of inositol deacylation in fungi and implications to host infection remains largely unexplored. Herein we describe our identification of BST1, an inositol deacylase of GPI-Aps in Candida albicans, was critical for GPI-APs cell wall attachment and host infection. BST1-deficient C. albicans (bst1Delta/Delta) was associated with severely impaired cell wall anchorage of GPI-APs and subsequen unmasked beta (1,3)-glucan. Consistent with the aberrant cell wall structures, bst1Delta/Delta strain did not display an invasive ability and could be recognized more efficiently by host immune systems. Moreover, BST1 null mutants or those expressing Bst1 variants did not display inositol deacylation activity and exhibited severely attenuated virulence and reduced organic colonization in a murine systemic candidiasis model. Thus, Bst1 can facilitate cell wall anchorage of GPI-APs in C. albicans by inositol deacylation, and is critical for host invasion and immune escape. PMID- 27708387 TI - Plant growth promoting rhizobacteria Dietzia natronolimnaea modulates the expression of stress responsive genes providing protection of wheat from salinity stress. AB - Plant growth promoting rhizobacteria (PGPR) hold promising future for sustainable agriculture. Here, we demonstrate a carotenoid producing halotolerant PGPR Dietzia natronolimnaea STR1 protecting wheat plants from salt stress by modulating the transcriptional machinery responsible for salinity tolerance in plants. The expression studies confirmed the involvement of ABA-signalling cascade, as TaABARE and TaOPR1 were upregulated in PGPR inoculated plants leading to induction of TaMYB and TaWRKY expression followed by stimulation of expression of a plethora of stress related genes. Enhanced expression of TaST, a salt stress induced gene, associated with promoting salinity tolerance was observed in PGPR inoculated plants in comparison to uninoculated control plants. Expression of SOS pathway related genes (SOS1 and SOS4) was modulated in PGPR-applied wheat shoots and root systems. Tissue-specific responses of ion transporters TaNHX1, TaHAK, and TaHKT1, were observed in PGPR-inoculated plants. The enhanced gene expression of various antioxidant enzymes such as APX, MnSOD, CAT, POD, GPX and GR and higher proline content in PGPR-inoculated wheat plants contributed to increased tolerance to salinity stress. Overall, these results indicate that halotolerant PGPR-mediated salinity tolerance is a complex phenomenon that involves modulation of ABA-signalling, SOS pathway, ion transporters and antioxidant machinery. PMID- 27708388 TI - The genetic map of goldfish (Carassius auratus) provided insights to the divergent genome evolutions in the Cyprinidae family. AB - A high-density linkage map of goldfish (Carassius auratus) was constructed using RNA-sequencing. This map consists of 50 linkage groups with 8,521 SNP markers and an average resolution of 0.62 cM. Approximately 84% of markers are in protein coding genes orthologous to zebrafish proteins. We performed comparative genome analysis between zebrafish and medaka, common carp, grass carp, and goldfish to study the genome evolution events in the Cyprinidae family. The comparison revealed large synteny blocks among Cyprinidae fish and we hypothesized that the Cyprinidae ancestor undergone many inter-chromosome rearrangements after speciation from teleost ancestor. The study also showed that goldfish genome had one more round of whole genome duplication (WGD) than zebrafish. Our results illustrated that most goldfish markers were orthologous to genes in common carp, which had four rounds of WGD. Growth-related regions and genes were identified by QTL analysis and association study. Function annotations of the associated genes suggested that they might regulate development and growth in goldfish. This first genetic map enables us to study the goldfish genome evolution and provides an important resource for selective breeding of goldfish. PMID- 27708389 TI - Cytoskeletal Configuration Modulates Mechanically Induced Changes in Mesenchymal Stem Cell Osteogenesis, Morphology, and Stiffness. AB - Mesenchymal stem cells (MSC) responding to mechanical cues generated by physical activity is critical for skeletal development and remodeling. Here, we utilized low intensity vibrations (LIV) as a physiologically relevant mechanical signal and hypothesized that the confined cytoskeletal configuration imposed by 2D culture will enable human bone marrow MSCs (hBMSC) to respond more robustly when LIV is applied in-plane (horizontal-LIV) rather than out-of-plane (vertical-LIV). All LIV signals enhanced hBMSC proliferation, osteogenic differentiation, and upregulated genes associated with cytoskeletal structure. The cellular response was more pronounced at higher frequencies (100 Hz vs 30 Hz) and when applied in the horizontal plane. Horizontal but not vertical LIV realigned the cell cytoskeleton, culminating in increased cell stiffness. Our results show that applying very small oscillatory motions within the primary cell attachment plane, rather than perpendicular to it, amplifies the cell's response to LIV, ostensibly facilitating a more effective transfer of intracellular forces. Transcriptional and structural changes in particular with horizontal LIV, together with the strong frequency dependency of the signal, emphasize the importance of intracellular cytoskeletal configuration in sensing and responding to high frequency mechanical signals at low intensities. PMID- 27708390 TI - Functional value of elytra under various stresses in the red flour beetle, Tribolium castaneum. AB - Coleoptera (beetles) is a massively successful order of insects, distinguished by their evolutionarily modified forewings called elytra. These structures are often presumed to have been a major driving force for the successful radiation of this taxon, by providing beetles with protection against a variety of harsh environmental factors. However, few studies have directly demonstrated the functional significance of the elytra against diverse environmental challenges. Here, we sought to empirically test the function of the elytra using Tribolium castaneum (the red flour beetle) as a model. We tested four categories of stress on the beetles: physical damage to hindwings, predation, desiccation, and cold shock. We found that, in all categories, the presence of elytra conferred a significant advantage compared to those beetles with their elytra experimentally removed. This work provides compelling quantitative evidence supporting the importance of beetle forewings in tolerating a variety of environmental stresses, and gives insight into how the evolution of elytra have facilitated the remarkable success of beetle radiation. PMID- 27708391 TI - Single cell dynamic phenotyping. AB - Live cell imaging has improved our ability to measure phenotypic heterogeneity. However, bottlenecks in imaging and image processing often make it difficult to differentiate interesting biological behavior from technical artifact. Thus there is a need for new methods that improve data quality without sacrificing throughput. Here we present a 3-step workflow to improve dynamic phenotype measurements of heterogeneous cell populations. We provide guidelines for image acquisition, phenotype tracking, and data filtering to remove erroneous cell tracks using the novel Tracking Aberration Measure (TrAM). Our workflow is broadly applicable across imaging platforms and analysis software. By applying this workflow to cancer cell assays, we reduced aberrant cell track prevalence from 17% to 2%. The cost of this improvement was removing 15% of the well-tracked cells. This enabled detection of significant motility differences between cell lines. Similarly, we avoided detecting a false change in translocation kinetics by eliminating the true cause: varied proportions of unresponsive cells. Finally, by systematically seeking heterogeneous behaviors, we detected subpopulations that otherwise could have been missed, including early apoptotic events and pre mitotic cells. We provide optimized protocols for specific applications and step by-step guidelines for adapting them to a variety of biological systems. PMID- 27708392 TI - Unique Features of Ethnic Mongolian Gut Microbiome revealed by metagenomic analysis. AB - The human gut microbiota varies considerably among world populations due to a variety of factors including genetic background, diet, cultural habits and socioeconomic status. Here we characterized 110 healthy Mongolian adults gut microbiota by shotgun metagenomic sequencing and compared the intestinal microbiome among Mongolians, the Hans and European cohorts. The results showed that the taxonomic profile of intestinal microbiome among cohorts revealed the Actinobaceria and Bifidobacterium were the key microbes contributing to the differences among Mongolians, the Hans and Europeans at the phylum level and genus level, respectively. Metagenomic species analysis indicated that Faecalibacterium prausnitzii and Coprococcus comeswere enrich in Mongolian people which might contribute to gut health through anti-inflammatory properties and butyrate production, respectively. On the other hand, the enriched genus Collinsella, biomarker in symptomatic atherosclerosis patients, might be associated with the high morbidity of cardiovascular and cerebrovascular diseases in Mongolian adults. At the functional level, a unique microbial metabolic pathway profile was present in Mongolian's gut which mainly distributed in amino acid metabolism, carbohydrate metabolism, energy metabolism, lipid metabolism, glycan biosynthesis and metabolism. We can attribute the specific signatures of Mongolian gut microbiome to their unique genotype, dietary habits and living environment. PMID- 27708393 TI - Splice variants of the CaV1.3 L-type calcium channel regulate dendritic spine morphology. AB - Dendritic spines are the postsynaptic compartments of glutamatergic synapses in the brain. Their number and shape are subject to change in synaptic plasticity and neurological disorders including autism spectrum disorders and Parkinson's disease. The L-type calcium channel CaV1.3 constitutes an important calcium entry pathway implicated in the regulation of spine morphology. Here we investigated the importance of full-length CaV1.3L and two C-terminally truncated splice variants (CaV1.342A and CaV1.343S) and their modulation by densin-180 and shank1b for the morphology of dendritic spines of cultured hippocampal neurons. Live-cell immunofluorescence and super-resolution microscopy of epitope-tagged CaV1.3L revealed its localization at the base-, neck-, and head-region of dendritic spines. Expression of the short splice variants or deletion of the C-terminal PDZ binding motif in CaV1.3L induced aberrant dendritic spine elongation. Similar morphological alterations were induced by co-expression of densin-180 or shank1b with CaV1.3L and correlated with increased CaV1.3 currents and dendritic calcium signals in transfected neurons. Together, our findings suggest a key role of CaV1.3 in regulating dendritic spine structure. Under physiological conditions it may contribute to the structural plasticity of glutamatergic synapses. Conversely, altered regulation of CaV1.3 channels may provide an important mechanism in the development of postsynaptic aberrations associated with neurodegenerative disorders. PMID- 27708395 TI - A hybrid tunable THz metadevice using a high birefringence liquid crystal. AB - We investigate a hybrid re-configurable three dimensional metamaterial based on liquid crystal as tuning element in order to build novel devices operating in the terahertz range. The proposed metadevice is an array of meta-atoms consisting of split ring resonators having suspended conducting cantilevers in the gap region. Adding a "third dimension" to a standard planar device plays a dual role: (i) enhance the tunability of the overall structure, exploiting the birefringence of the liquid crystal at its best, and (ii) improve the field confinement and therefore the ability of the metadevice to efficiently steer the THz signal. We describe the design, electromagnetic simulation, fabrication and experimental characterization of this new class of tunable metamaterials under an externally applied small voltage. By infiltrating tiny quantities of a nematic liquid crystal in the structure, we induce a frequency shift in the resonant response of the order of 7-8% in terms of bandwidth and about two orders of magnitude change in the signal absorption. We discuss how such a hybrid structure can be exploited for the development of a THz spatial light modulator. PMID- 27708394 TI - Fragment-based de novo design of a cystathionine gamma-lyase selective inhibitor blocking hydrogen sulfide production. AB - Hydrogen sulfide is an essential catabolite that intervenes in the pathophysiology of several diseases from hypertension to stroke, diabetes and pancreatitis. It is endogenously synthesized mainly by two pyridoxal-5'-phosphate dependent enzymes involved in L-cysteine metabolism: cystathionine-beta-synthase (CBS) and cystathionine-gamma-lyase (CSE). Research in this field is currently impaired by the lack of pharmacological tools such as selective enzymatic inhibitors that could target specifically only one of these pathways. We used a novel approach based on a hybrid method that includes drug design, synthetic biology, metabolomics and pharmacological assays to rationally design a new inhibitor selective for the CSE enzyme. The identification of this compound opens new frontiers towards a better understanding of the role of CSE over CBS in the pathophysiology of diseases where a role for the H2S pathway has been proposed and the development of new lead compounds that could target the CSE enzyme. PMID- 27708396 TI - ERK/c-Jun Recruits Tet1 to Induce Zta Expression and Epstein-Barr Virus Reactivation through DNA Demethylation. AB - DNA demethylation plays an essential role in the reactivation of Epstein-Barr virus (EBV) from latency infection. However, it is unclear how epigenetic modification is initiated in responding to stimuli. Here, we demonstrate that ERK/c-Jun signaling is involved in DNA demethylation of EBV immediate early (IE) gene Zta in response to 12-O-Tetradecanoylphorbol-13-acetate (TPA) stimulation. Remarkably, Ser73 phosphorylation of c-Jun facilitates Zta promoter demethylation and EBV reactivation, whereas knockdown of c-Jun attenuates Zta demethylation and viral reactivation. More importantly, we reveal for the first time that c-Jun interacts with DNA dioxygenase Tet1 and facilitates Tet1 to bind to Zta promoter. The binding of c-Jun and Tet1 to Zta enhances promoter demethylation, resulting in the activation of Zta, the stimulation of BHRF1 (a lytic early gene) and gp350/220 (a lytic late gene), and ultimately the reactivation of EBV. Knockdown of Tet1 attenuates TPA-induced Zta demethylation and EBV reactivation. Thus, TPA activates ERK/c-Jun signaling, which subsequently facilitates Tet1 to bind to Zta promoter, leading to DNA demethylation, gene expression, and EBV reactivation. This study reveals important roles of ERK/c-Jun signaling and Tet1 dioxygenase in epigenetic modification, and provides new insights into the mechanism underlying the regulation of virus latent and lytic infection. PMID- 27708398 TI - Unidirectional superscattering by multilayered cavities of effective radial anisotropy. AB - We achieve unidirectional forward superscattering by multilayered spherical cavities which are effectively radially anisotropic. It is demonstrated that, relying on the large effective anisotropy, the electric and magnetic dipoles can be tuned to spectrally overlap in such cavities, which satisfies the Kerker's condition of simultaneous backward scattering suppression and forward scattering enhancement. We show that such scattering pattern shaping can be obtained in both all-dielectric and plasmonic multilayered cavities at different spectral positions, and believe that the mechanism we have revealed provides extra freedom for scattering shaping, which may play a significant role in many scattering related applications and also in optoelectronic devices made up of intrinsically anisotropic two dimensional materials. PMID- 27708397 TI - CXCL13/CXCR5 enhances sodium channel Nav1.8 current density via p38 MAP kinase in primary sensory neurons following inflammatory pain. AB - CXCL13 is a B lymphocyte chemoattractant and activates CXCR5 receptor in the immune system. Here we investigated whether CXCL13/CXCR5 mediates inflammatory pain in dorsal root ganglia (DRG) and the underlying mechanisms. Peripheral injection of complete Freund's Adjuvant (CFA) increased the expression of CXCL13 and CXCR5 in DRG neurons. In Cxcr5-/- mice, CFA-induced pain hypersensitivity were attenuated. Whole-cell patch-clamp recording showed that the excitability of dissociated DRG neurons was increased after CFA injection or CXCL13 incubation from wild-type (WT) mice, but not from Cxcr5-/- mice. Additionally, sodium channel Nav1.8 was co-expressed with CXCR5 in dissociated DRG neurons, and the increased neuronal excitability induced by CFA or CXCL13 was reduced by Nav1.8 blocker. Intrathecal injection of Nav1.8 blocker also attenuated intrathecal injection of CXCL13-induced pain hypersensitivity. Furthermore, CXCL13 increased Nav1.8 current density in DRG neurons, which was inhibited by p38 MAP kinase inhibitor. CFA and CXCL13 increased p38 phosphorylation in the DRG of WT mice but not Cxcr5-/- mice. Finally, intrathecal p38 inhibitor alleviated CXCL13-induced pain hypersensitivity. Taken together, these results demonstrated that CXCL13, upregulated by peripheral inflammation, acts on CXCR5 on DRG neurons and activates p38, which increases Nav1.8 current density and further contributes to the maintenance of inflammatory pain. PMID- 27708399 TI - Controllable growth of vertically aligned graphene on C-face SiC. AB - We investigated how to control the growth of vertically aligned graphene on C face SiC by varying the processing conditions. It is found that, the growth rate scales with the annealing temperature and the graphene height is proportional to the annealing time. Temperature gradient and crystalline quality of the SiC substrates influence their vaporization. The partial vapor pressure is crucial as it can interfere with further vaporization. A growth mechanism is proposed in terms of physical vapor transport. The monolayer character of vertically aligned graphene is verified by Raman and X-ray absorption spectroscopy. With the processed samples, d0 magnetism is realized and negative magnetoresistance is observed after Cu implantation. We also prove that multiple carriers exist in vertically aligned graphene. PMID- 27708400 TI - Systemic sclerosis: The future is CD56-bright. PMID- 27708401 TI - Connective tissue diseases: Promises and challenges of metabolomics in SLE. PMID- 27708402 TI - Easy on-demand single-pass self-assembly and modification to fabricate gold@graphene-based anti-inflammatory nanoplatforms. AB - Zwitterionic chitosan (ZC) was modified by fully (both for lateral dimension and thickness) nanodimensional gold-graphene oxide (Au@GO) flakes under visible light and the potential of the resulting materials as biomedical nanoplatforms was investigated. Fully nanodimensional GO flakes floating in nitrogen gas were incorporated with Au nanoparticles to form Au@GO nanoflakes, and the Au@GO was then incorporated with ZC droplets to form the Au@GO-ZC hybrid nanoparticles. The collected particles were exposed to visible light to induce the photocatalytic activity of the Au@GO nanoflakes towards the ZC derivatives. The visible-light exposed particles show different chemical and surface properties from the unexposed particles, while there were no significant differences in cytotoxicity and macrophage inflammatory protein production. This work suggests that incorporating fully nanodimensional Au@GO flakes with ZC is a suitable technique for ambient photo-modification of the chitosans' surface property without significant changes in size and shape and increases in cytotoxicity and inflammatory response. PMID- 27708403 TI - Dissecting the contribution of Staphylococcus aureus alpha-phenol-soluble modulins to biofilm amyloid structure. AB - The opportunistic pathogen Staphylococcus aureus is recognized as one of the most frequent causes of biofilm-associated infections. The recently discovered phenol soluble modulins (PSMs) are small alpha-helical amphipathic peptides that act as the main molecular effectors of staphylococcal biofilm maturation, promoting the formation of an extracellular fibril structure with amyloid-like properties. Here, we combine computational, biophysical and in cell analysis to address the specific contribution of individual PSMs to biofilm structure. We demonstrate that despite their highly similar sequence and structure, contrary to what it was previously thought, not all PSMs participate in amyloid fibril formation. A balance of hydrophobic/hydrophilic forces and helical propensity seems to define the aggregation propensity of PSMs and control their assembly and function. This knowledge would allow to target specifically the amyloid properties of these peptides. In this way, we show that Epigallocatechin-3-gallate (EGCG), the principal polyphenol in green tea, prevents the assembly of amyloidogenic PSMs and disentangles their preformed amyloid fibrils. PMID- 27708404 TI - Replenishment of microRNA-188-5p restores the synaptic and cognitive deficits in 5XFAD Mouse Model of Alzheimer's Disease. AB - MicroRNAs have emerged as key factors in development, neurogenesis and synaptic functions in the central nervous system. In the present study, we investigated a pathophysiological significance of microRNA-188-5p (miR-188-5p) in Alzheimer's disease (AD). We found that oligomeric Abeta1-42 treatment diminished miR-188-5p expression in primary hippocampal neuron cultures and that miR-188-5p rescued the Abeta1-42-mediated synapse elimination and synaptic dysfunctions. Moreover, the impairments in cognitive function and synaptic transmission observed in 7-month old five familial AD (5XFAD) transgenic mice, were ameliorated via viral-mediated expression of miR-188-5p. miR-188-5p expression was down-regulated in the brain tissues from AD patients and 5XFAD mice. The addition of miR-188-5p rescued the reduction in dendritic spine density in the primary hippocampal neurons treated with oligomeric Abeta1-42 and cultured from 5XFAD mice. The reduction in the frequency of mEPSCs was also restored by addition of miR-188-5p. The impairments in basal fEPSPs and cognition observed in 7-month-old 5XFAD mice were ameliorated via the viral-mediated expression of miR-188-5p in the hippocampus. Furthermore, we found that miR-188 expression is CREB-dependent. Taken together, our results suggest that dysregulation of miR-188-5p expression contributes to the pathogenesis of AD by inducing synaptic dysfunction and cognitive deficits associated with Abeta-mediated pathophysiology in the disease. PMID- 27708405 TI - A fragment-based approach applied to a highly flexible target: Insights and challenges towards the inhibition of HSP70 isoforms. AB - The heat shock protein 70s (HSP70s) are molecular chaperones implicated in many cancers and of significant interest as targets for novel cancer therapies. Several HSP70 inhibitors have been reported, but because the majority have poor physicochemical properties and for many the exact mode of action is poorly understood, more detailed mechanistic and structural insight into ligand-binding to HSP70s is urgently needed. Here we describe the first comprehensive fragment based inhibitor exploration of an HSP70 enzyme, which yielded an amino quinazoline fragment that was elaborated to a novel ATP binding site ligand with different physicochemical properties to known adenosine-based HSP70 inhibitors. Crystal structures of amino-quinazoline ligands bound to the different conformational states of the HSP70 nucleotide binding domain highlighted the challenges of a fragment-based approach when applied to this particular flexible enzyme class with an ATP-binding site that changes shape and size during its catalytic cycle. In these studies we showed that Ser275 is a key residue in the selective binding of ATP. Additionally, the structural data revealed a potential functional role for the ATP ribose moiety in priming the protein for the formation of the ATP-bound pre-hydrolysis complex by influencing the conformation of one of the phosphate binding loops. PMID- 27708406 TI - Structural and Functional Characterization of the VQ Protein Family and VQ Protein Variants from Soybean. AB - Proteins containing the FxxxVQxhTG or VQ motif interact with WRKY transcription factors. Although VQ proteins have been reported in several plants, knowledge about their structures, functions and evolution is still very limited. Here, we report structural and functional analysis of the VQ protein family from soybean. Like Arabidopsis homologues, soybean VQ proteins bind only Group I and IIc WRKY proteins and a substantial number of their genes are responsive to stress associated phytohormones. Overexpression of some soybean VQ genes in Arabidopsis had strong effects on plant growth, development, disease resistance and heat tolerance. Phylogenetic analysis, sequence alignment and site-directed mutagenesis revealed that the region immediately upstream of the FxxxVQxhTG motif also affects binding to WRKY proteins. Consistent with a larger WRKY-binding VQ domain, soybean VQ22 protein from cultivated soybean contains a 4-amino acid deletion in the region preceding its VQ motif that completely abolishes its binding to WRKY proteins. By contrast, the 4-amino acid deletion is absent in the VQ22 protein from wild soybean species (Glycine soja). Overexpression of wild soybean VQ22 in cultivated soybean inhibited growth, particularly after cold treatment. Thus, the mutation of soybean VQ22 is associated with advantageous phenotypes and may have been positively selected during evolution. PMID- 27708407 TI - Developing a genetic manipulation system for the Antarctic archaeon, Halorubrum lacusprofundi: investigating acetamidase gene function. AB - No systems have been reported for genetic manipulation of cold-adapted Archaea. Halorubrum lacusprofundi is an important member of Deep Lake, Antarctica (~10% of the population), and is amendable to laboratory cultivation. Here we report the development of a shuttle-vector and targeted gene-knockout system for this species. To investigate the function of acetamidase/formamidase genes, a class of genes not experimentally studied in Archaea, the acetamidase gene, amd3, was disrupted. The wild-type grew on acetamide as a sole source of carbon and nitrogen, but the mutant did not. Acetamidase/formamidase genes were found to form three distinct clades within a broad distribution of Archaea and Bacteria. Genes were present within lineages characterized by aerobic growth in low nutrient environments (e.g. haloarchaea, Starkeya) but absent from lineages containing anaerobes or facultative anaerobes (e.g. methanogens, Epsilonproteobacteria) or parasites of animals and plants (e.g. Chlamydiae). While acetamide is not a well characterized natural substrate, the build-up of plastic pollutants in the environment provides a potential source of introduced acetamide. In view of the extent and pattern of distribution of acetamidase/formamidase sequences within Archaea and Bacteria, we speculate that acetamide from plastics may promote the selection of amd/fmd genes in an increasing number of environmental microorganisms. PMID- 27708410 TI - Low Complexity Compression and Speed Enhancement for Optical Scanning Holography. AB - In this paper we report a low complexity compression method that is suitable for compact optical scanning holography (OSH) systems with different optical settings. Our proposed method can be divided into 2 major parts. First, an automatic decision maker is applied to select the rows of holographic pixels to be scanned. This process enhances the speed of acquiring a hologram, and also lowers the data rate. Second, each row of down-sampled pixels is converted into a one-bit representation with delta modulation (DM). Existing DM-based hologram compression techniques suffers from the disadvantage that a core parameter, commonly known as the step size, has to be determined in advance. However, the correct value of the step size for compressing each row of hologram is dependent on the dynamic range of the pixels, which could deviate significantly with the object scene, as well as OSH systems with different opical settings. We have overcome this problem by incorporating a dynamic step-size adjustment scheme. The proposed method is applied in the compression of holograms that are acquired with 2 different OSH systems, demonstrating a compression ratio of over two orders of magnitude, while preserving favorable fidelity on the reconstructed images.

AB - PTEN is a tyrosine phosphatase with significant function in inhibiting STAT3 activation. Recently, inactivation of STAT3 has been demonstrated as a therapeutic candidate for autoimmune arthritis. The expression of PTEN controlled by p53 regulates autoimmune arthritis through modulating the balance between Th17 and Treg. We hypothesized that PTEN regulated by p53 might reduce CIA severity and inflammatory response via inhibiting STAT3 activation. Our results revealed that PTEN could ameliorate experimental autoimmune arthritis by reducing STAT3 activity and Th17 differentiation. Systemic infusion of PTEN overexpression downregulated CIA severity. In addition, PTEN overexpression decreased the activation of T cells and modulated reciprocal differentiation of Th17 and Treg cells. We observed that PTEN expression downregulated by p53 deficiency induced the activation of STAT3. Loss of p53 exacerbated autoimmune arthritis and dysregulated the population of Th17 and Treg. These data suggest that induction of STAT3-modulatory activity of PTEN may be a therapeutic target for rheumatoid arthritis therapy.

AB - Hyperoxaluria due to endogenously synthesized and exogenously ingested oxalates is a leading cause of recurrent oxalate stone formations. Even though, humans largely rely on gut microbiota for oxalate homeostasis, hyperoxaluria associated gut microbiota features remain largely unknown. Based on 16S rRNA gene amplicons, targeted metagenomic sequencing of formyl-CoA transferase (frc) gene and qPCR assay, we demonstrate a selective enrichment of Oxalate Metabolizing Bacterial Species (OMBS) in hyperoxaluria condition. Interestingly, higher than usual concentration of oxalate was found inhibitory to many gut microbes, including Oxalobacter formigenes, a well-characterized OMBS. In addition a concomitant enrichment of acid tolerant pathobionts in recurrent stone sufferers is observed. Further, specific enzymes participating in oxalate metabolism are found augmented in stone endures. Additionally, hyperoxaluria driven dysbiosis was found to be associated with oxalate content, stone episodes and colonization pattern of Oxalobacter formigenes. Thus, we rationalize the first in-depth surveillance of OMBS in the human gut and their association with hyperoxaluria. Our findings can be utilized in the treatment of hyperoxaluria associated recurrent stone episodes.

AB - Modern optical fibers require double-layer coating on the glass fiber to provide protection from signal attenuation and mechanical damage. The most important plastic resins used in wires and optical fibers are plastic polyvinyl chloride (PVC) and low-high density polyethylene (LDPE/HDPE), nylon and Polysulfone. In this paper, double-layer optical fiber coating is performed using melt polymer satisfying PTT fluid model in a pressure type die using wet-on-wet coating process. The assumption of fully developed flow of Phan-Thien-Tanner (PTT) fluid model, two-layer liquid flows of an immiscible fluid is modeled in an annular die, where the fiber is dragged at a higher speed. The equations characterizing the flow and heat transfer phenomena are solved exactly and the effects of emerging parameters (Deborah and slip parameters, characteristic velocity, radii ratio and Brinkman numbers on the axial velocity, flow rate, thickness of coated fiber optics, and temperature distribution) are reported in graphs. It is shown that an increase in the non-Newtonian parameters increase the velocity in the absence or presence of slip parameters which coincides with related work. The comparison is done with experimental work by taking lambda -> 0 (non-Newtonian parameter). PMID- 27708411 TI - DNA annealing by Redbeta is insufficient for homologous recombination and the additional requirements involve intra- and inter-molecular interactions. AB - Single strand annealing proteins (SSAPs) like Redbeta initiate homologous recombination by annealing complementary DNA strands. We show that C-terminally truncated Redbeta, whilst still able to promote annealing and nucleoprotein filament formation, is unable to mediate homologous recombination. Mutations of the C-terminal domain were evaluated using both single- and double stranded (ss and ds) substrates in recombination assays. Mutations of critical amino acids affected either dsDNA recombination or both ssDNA and dsDNA recombination indicating two separable functions, one of which is critical for dsDNA recombination and the second for recombination per se. As evaluated by co immunoprecipitation experiments, the dsDNA recombination function relates to the Redalpha-Redbeta protein-protein interaction, which requires not only contacts in the C-terminal domain but also a region near the N-terminus. Because the nucleoprotein filament formed with C-terminally truncated Redbeta has altered properties, the second C-terminal function could be due to an interaction required for functional filaments. Alternatively the second C-terminal function could indicate a requirement for a Redbeta-host factor interaction. These data further advance the model for Red recombination and the proposition that Redbeta and RAD52 SSAPs share ancestral and mechanistic roots. PMID- 27708413 TI - Normative data for the segmental acquisition of contact heat evoked potentials in cervical dermatomes. AB - Contact heat evoked potentials (CHEPs) represent a neurophysiological approach to assess conduction in the spinothalamic tract. The aim of this study was to establish normative values of CHEPs acquired from cervical dermatomes (C4, C6, C8) and examine the potential confounds of age, sex, and height. 101 (49 male) healthy subjects of three different age groups (18-40, 41-60, and 61-80 years) were recruited. Normal (NB, 35-52 degrees C) followed by increased (IB, 42-52 degrees C) baseline stimulation protocols were employed to record CHEPs. Multi variate linear models were used to investigate the effect of age, sex, and height on the CHEPs parameters (i.e., N2 latency, N2P2 amplitude, rating of perceived intensity). Compared to NB, IB stimulation reduced latency jitter within subjects, yielding larger N2P2 amplitudes, and decreased inter-subject N2 latency variability. Age was associated with reduced N2P2 amplitude and prolonged N2 latency. After controlling for height, male subjects had significantly longer N2 latencies than females during IB stimulation. The study provides normative CHEPs data in a large cohort of healthy subjects from segmentally examined cervical dermatomes. Age and sex were identified as important factors contributing to N2 latency and N2P2 amplitude. The normative data will improve the diagnosis of spinal cord pathologies. PMID- 27708415 TI - High-Throughput Design of Two-Dimensional Electron Gas Systems Based on Polar/Nonpolar Perovskite Oxide Heterostructures. AB - The two-dimensional electron gas (2DEG) formed at the interface between two insulating oxides such as LaAlO3 and SrTiO3 (STO) is of fundamental and practical interest because of its novel interfacial conductivity and its promising applications in next-generation nanoelectronic devices. Here we show that a group of combinatorial descriptors that characterize the polar character, lattice mismatch, band gap, and the band alignment between the perovskite-oxide-based band insulators and the STO substrate, can be introduced to realize a high throughput (HT) design of SrTiO3-based 2DEG systems from perovskite oxide quantum database. Equipped with these combinatorial descriptors, we have carried out a HT screening of all the polar perovskite compounds, uncovering 42 compounds of potential interests. Of these, Al-, Ga-, Sc-, and Ta-based compounds can form a 2DEG with STO, while In-based compounds exhibit a strain-induced strong polarization when deposited on STO substrate. In particular, the Ta-based compounds can form 2DEG with potentially high electron mobility at (TaO2)+/(SrO)0 interface. Our approach, by defining materials descriptors solely based on the bulk materials properties, and by relying on the perovskite-oriented quantum materials repository, opens new avenues for the discovery of perovskite-oxide based functional interface materials in a HT fashion. PMID- 27708414 TI - Association between dietary patterns and metabolic syndrome in Chinese adults: a propensity score-matched case-control study. AB - Previous studies indicated that dietary patterns were associated with metabolic syndrome (MS), but little is known in Chinese. We design this case-control study to evaluate the associations between dietary patterns and MS in Chinese adults. In this study, 1492 participants with MS were matched with 1492 controls using the 1:1 ratio propensity score matching methods. Dietary intake was assessed using a valid self-administered food frequency questionnaire, and MS was defined in accordance with the criteria of the American Heart Association scientific statement of 2009. Higher scores for the high-protein/cholesterol pattern were associated with higher prevalence of MS. Compared with the participants in the lowest quartile, the odds ratio (OR) for the extreme quartile was 1.36 (95% confidence interval (CI), 1.10-1.68) and the P for trend <0.01 after adjusted for the other two dietary pattern scores. We also found a moderate consumption of the balanced pattern was associated with the lowest prevalence of MS. The ORs across quartiles of the balanced pattern were 1 (reference), 0.83 (95% CI, 0.68-1.02), 0.69 (95% CI, 0.56-0.85), and 0.84 (95% CI, 0.68-1.04) after adjustment. Our study demonstrates that there is a strong association between a diet rich in animal offal, animal blood, meat, and sausage and a higher prevalence of MS. PMID- 27708416 TI - Loss of Atg16 delays the alcohol-induced sedation response via regulation of Corazonin neuropeptide production in Drosophila. AB - Autophagy defects lead to the buildup of damaged proteins and organelles, reduced survival during starvation and infections, hypersensitivity to stress and toxic substances, and progressive neurodegeneration. Here we show that, surprisingly, Drosophila mutants lacking the core autophagy gene Atg16 are not only defective in autophagy but also exhibit increased resistance to the sedative effects of ethanol, unlike Atg7 or Atg3 null mutant flies. This mutant phenotype is rescued by the re-expression of Atg16 in Corazonin (Crz)-producing neurosecretory cells that are known to promote the sedation response during ethanol exposure, and RNAi knockdown of Atg16 specifically in these cells also delays the onset of ethanol induced coma. We find that Atg16 and Crz colocalize within these neurosecretory cells, and both Crz protein and mRNA levels are decreased in Atg16 mutant flies. Thus, Atg16 promotes Crz production to ensure a proper organismal sedation response to ethanol. PMID- 27708417 TI - Critical Role of Transcription Factor PU.1 in the Function of the OX40L/TNFSF4 Promoter in Dendritic Cells. AB - PU.1 is a hematopoietic lineage-specific transcription factor belonging to the Ets family. We investigated the role of PU.1 in the expression of OX40L in dendritic cells (DCs), because the regulatory mechanism of cell type-specific expression of OX40L, which is mainly restricted to antigen-presenting cells, is largely unknown despite the critical involvement in Th2 and Tfh development. PU.1 knockdown decreased the expression of OX40L in mouse DCs. Chromatin immunoprecipitation (ChIP) assays demonstrated that PU.1 constitutively bound to the proximal region of the OX40L promoter. Reporter assays and electrophoretic mobility shift assays revealed that PU.1 transactivated the OX40L promoter through direct binding to the most-proximal Ets motif. We found that this Ets motif is conserved between mouse and human, and that PU.1 bound to the human OX40L promoter in ChIP assay using human monocyte-derived DCs. ChIP assays based on ChIP-seq datasets revealed that PU.1 binds to several sites distant from the transcription start site on the OX40L gene in addition to the most-proximal site in mouse DCs. In the present study, the structure of the OX40L promoter regulated by PU.1 is determined. It is also suggested that PU.1 is involved in mouse OX40L expression via multiple binding sites on the gene. PMID- 27708418 TI - B cell-derived transforming growth factor-beta1 expression limits the induction phase of autoimmune neuroinflammation. AB - Studies in experimental autoimmune encephalomyelitis (EAE), a murine model of multiple sclerosis (MS), have shown that regulatory B cells modulate the course of the disease via the production of suppressive cytokines. While data indicate a role for transforming growth factor (TGF)-beta1 expression in regulatory B cell functions, this mechanism has not yet been tested in autoimmune neuroinflammation. Transgenic mice deficient for TGF-beta1 expression in B cells (B-TGF-beta1-/-) were tested in EAE induced by recombinant mouse myelin oligodendrocyte glycoprotein (rmMOG). In this model, B-TGF-beta1-/- mice showed an earlier onset of neurologic impairment compared to their littermate controls. Exacerbated EAE susceptibility in B-TGF-beta1-/- mice was associated with augmented CNS T helper (Th)1/17 responses. Moreover, selective B cell TGF-beta1 deficiency increased the frequencies and activation of myeloid dendritic cells, potent professional antigen-presenting cells (APCs), suggesting that B cell derived TGF-beta1 can constrain Th1/17 responses through inhibition of APC activity. Collectively our data suggest that B cells can down-regulate the function of APCs, and in turn encephalitogenic Th1/17 responses, via TGF-beta1, findings that may be relevant to B cell-targeted therapies. PMID- 27708421 TI - Depth-distribution patterns and control of soil organic carbon in coastal salt marshes with different plant covers. AB - This study was carried out in three kinds of salt marshes according to the vegetation covers, including Phragmites australis salt marsh (PSM), Suaeda salus salt marsh (SSM) and Tamarix chinensis-Suaeda salus salt marsh (TSSM). We applied allometric function, exponential function and logistic function to model the depth distribution of the SOCv and SOCc for each salt marsh, respectively. The results showed that the exponential function fits the depth distribution of the SOCv more well than other two functions. The SOCc can be fitted very well by all three functions for three salt marsh (Adj. R2 > 0.99), of which the allometric function was the best one. The mean topsoil concentration factors (TCFs) of three salt marshes were beyond 0.1, which means the SOC enrichment in surface soils due to plant cycling, but TCFs in PSM were significantly higher than those in SSM (P < 0.05). Nearly 30% of SOC was concentrated in the top 20 cm soils. The results of general linear model (GLM) suggested that four soil properties (soil water content, pH, soil salt content and silt+clay) and their interactive effects explained about 80% of the total variation of SOC stock in the top 20 cm soils and the 20-100 cm soil layers. PMID- 27708419 TI - Suppression of the CD8 T cell response by human papillomavirus type 16 E7 occurs in Langerhans cell-depleted mice. AB - Human papillomavirus (HPV) is an epitheliotropic virus that is the primary causal agent for cervical cancer. Langerhans cells (LC) are skin antigen presenting cells that are reduced in number in HPV-infected skin. The aim of this study was to understand the immune-modulatory effects of HPV16 E7 on LC and on the CD8 T cell response to a skin-expressed antigen. To test this, HPV16 E7 was expressed in mouse skin keratinocytes with the model antigen ovalbumin (Ova). Similar to what is observed in HPV-infected human skin, LC numbers were significantly reduced in E7-expressing mouse skin. This shows that expression of the E7 protein alone is sufficient to mediate LC depletion. Expression of E7 with Ova in keratinocytes strongly suppressed the Ova-specific CD8+ T cell response in the skin draining lymph node. When tested in LC-ablated mice, the CD8 T cell response to skin-expressed Ova in control mice was not affected, nor was the T cell response to Ova restored in E7-expressing skin. These data indicate a role for E7 in regulation of LC homeostasis in the skin and in suppression of antigen specific CD8 T cell expansion, but suggest that these two effects occur independent of each other. PMID- 27708422 TI - Identification of doublesex alleles associated with the female-limited Batesian mimicry polymorphism in Papilio memnon. AB - The female-limited Batesian mimicry polymorphism in Papilio butterflies is an intriguing system for investigating the mechanism of maintenance of genetic polymorphisms. In Papilio polytes, an autosomal region encompassing the sex determinant gene doublesex controls female-limited mimicry polymorphism. In the closely related species P. memnon, which also exhibits female-limited Batesian mimicry polymorphism, we identified two allelic sequences of the doublesex gene that corresponded exactly with the mimetic and non-mimetic female phenotypes. Thus, the genetic basis of the mimicry polymorphism in P. memnon is similar to that in P. polytes. However, the mimetic and non-mimetic alleles of the two species were not identical, and the divergence of alleles occurred independently in P. memnon and P. polytes. Different mutation-selection processes may have resulted in the convergent patterns of mimicry polymorphism in these Papilio butterflies. PMID- 27708420 TI - Diaphanous gene mutation affects spiral cleavage and chirality in snails. AB - L-R (left and right) symmetry breaking during embryogenesis and the establishment of asymmetric body plan are key issues in developmental biology, but the onset including the handedness-determining gene locus still remains unknown. Using pure dextral (DD) and sinistral (dd) strains of the pond snail Lymnaea stagnalis as well as its F2 through to F10 backcrossed lines, the single handedness determining-gene locus was mapped by genetic linkage analysis, BAC cloning and chromosome walking. We have identified the actin-related diaphanous gene Lsdia1 as the strongest candidate. Although the cDNA and derived amino acid sequences of the tandemly duplicated Lsdia1 and Lsdia2 genes are very similar, we could discriminate the two genes/proteins in our molecular biology experiments. The Lsdia1 gene of the sinistral strain carries a frameshift mutation that abrogates full-length LsDia1 protein expression. In the dextral strain, it is already translated prior to oviposition. Expression of Lsdia1 (only in the dextral strain) and Lsdia2 (in both chirality) decreases after the 1-cell stage, with no asymmetric localization throughout. The evolutionary relationships among body handedness, SD/SI (spiral deformation/spindle inclination) at the third cleavage, and expression of diaphanous proteins are discussed in comparison with three other pond snails (L. peregra, Physa acuta and Indoplanorbis exustus). PMID- 27708423 TI - lncScore: alignment-free identification of long noncoding RNA from assembled novel transcripts. AB - RNA-Seq based transcriptome assembly has been widely used to identify novel lncRNAs. However, the best-performing transcript reconstruction methods merely identified 21% of full-length protein-coding transcripts from H. sapiens. Those partial-length protein-coding transcripts are more likely to be classified as lncRNAs due to their incomplete CDS, leading to higher false positive rate for lncRNA identification. Furthermore, potential sequencing or assembly error that gain or abolish stop codons also complicates ORF-based prediction of lncRNAs. Therefore, it remains a challenge to identify lncRNAs from the assembled transcripts, particularly the partial-length ones. Here, we present a novel alignment-free tool, lncScore, which uses a logistic regression model with 11 carefully selected features. Compared to other state-of-the-art alignment-free tools (e.g. CPAT, CNCI, and PLEK), lncScore outperforms them on accurately distinguishing lncRNAs from mRNAs, especially partial-length mRNAs in the human and mouse datasets. In addition, lncScore also performed well on transcripts from five other species (Zebrafish, Fly, C. elegans, Rat, and Sheep). To speed up the prediction, multithreading is implemented within lncScore, and it only took 2 minute to classify 64,756 transcripts and 54 seconds to train a new model with 21,000 transcripts with 12 threads, which is much faster than other tools. lncScore is available at https://github.com/WGLab/lncScore. PMID- 27708424 TI - Aromatic and proteomic analyses corroborate the distinction between Mediterranean landraces and modern varieties of durum wheat. AB - In this paper volatile organic compounds (VOCs) from durum wheat cultivars and landraces were analyzed using PTR-TOF-MS. The aim was to characterize the VOC's profile of the wholemeal flour and of the kernel to find out if any VOCs were specific to varieties and sample matrices. The VOC data is accompanied by SDS PAGE analyses of the storage proteins (gliadins and glutenins). Statistical analyses was carried out both on the signals obtained by MS and on the protein profiles. The difference between the VOC profile of two cultivars or two preparations of the same sample - matrices, in this case kernel vs wholemeal flour - can be very subtle; the high resolution of PTR-TOF-MS - down to levels as low as pptv - made it possible to recognize these differences. The effects of grinding on the VOC profiles were analyzed using SIMPER and Tanglegram statistical methods. Our results show that it is possible describe samples using VOC profiles and protein data. PMID- 27708425 TI - Genetic and clinical characterization of Pakistani families with Bardet-Biedl syndrome extends the genetic and phenotypic spectrum. AB - Bardet-Biedl syndrome (BBS) is an autosomal recessive disorder that is both genetically and clinically heterogeneous. To date 19 genes have been associated with BBS, which encode proteins active at the primary cilium, an antenna-like organelle that acts as the cell's signaling hub. In the current study, a combination of mutation screening, targeted sequencing of ciliopathy genes associated with BBS, and whole-exome sequencing was used for the genetic characterization of five families including four with classic BBS symptoms and one BBS-like syndrome. This resulted in the identification of novel mutations in BBS genes ARL6 and BBS5, and recurrent mutations in BBS9 and CEP164. In the case of CEP164, this is the first report of two siblings with a BBS-like syndrome with mutations in this gene. Mutations in this gene were previously associated with nephronophthisis 15, thus the current results expand the CEP164-associated phenotypic spectrum. The clinical and genetic spectrum of BBS and BBS-like phenotypes is not fully defined in Pakistan. Therefore, genetic studies are needed to gain insights into genotype-phenotype correlations, which will in turn improve the clinician's ability to make an early and accurate diagnosis, and facilitate genetic counseling, leading to directly benefiting families with affected individuals. PMID- 27708427 TI - Switchable thulium-doped fiber laser from polarization rotation vector to scalar soliton. AB - We experimentally demonstrate switchable temporal soliton generation from a thulium-doped fiber laser (TDFL), using carbon nanotubes as the mode-locker. With the help of residual polarization dependent loss of a wavelength division multiplexer, a weak nonlinear polarization rotation (NPR) effect can be achieved within the laser cavity, which may provide joint contribution for passive mode locking operation. By finely adjusting the polarization to alter the strength of NPR-based saturable absorption, the TDFL either approaches the operation regime of scalar soliton with strong NPR effect, or generates polarization rotation locked vector soliton (PRLVS) with weak NPR effect. The scalar solitons and PRLVSs possess 3-dB optical spectrum bandwidth of 2.2 nm and 2 nm, pulse-width of 1.8 ps and 2 ps, respectively. Moreover, the PRLVSs demonstrate a typical energy exchange between two polarized components on optical spectra and a period doubling feature in time domain. Such operation principle can also be used in 1550 nm band fiber lasers and other nonlinear systems. PMID- 27708426 TI - Acetylation Mimics Within a Single Nucleosome Alter Local DNA Accessibility In Compacted Nucleosome Arrays. AB - The activation of a silent gene locus is thought to involve pioneering transcription factors that initiate changes in the local chromatin structure to increase promoter accessibility and binding of downstream effectors. To better understand the molecular requirements for the first steps of locus activation, we investigated whether acetylation of a single nucleosome is sufficient to alter DNA accessibility within a condensed 25-nucleosome array. We found that acetylation mimics within the histone H4 tail domain increased accessibility of the surrounding linker DNA, with the increased accessibility localized to the immediate vicinity of the modified nucleosome. In contrast, acetylation mimics within the H3 tail had little effect, but were able to synergize with H4 tail acetylation mimics to further increase accessibility. Moreover, replacement of the central nucleosome with a nucleosome free region also resulted in increased local, but not global DNA accessibility. Our results indicate that modification or disruption of only a single target nucleosome results in significant changes in local chromatin architecture and suggest that very localized chromatin modifications imparted by pioneer transcription factors are sufficient to initiate a cascade of events leading to promoter activation. PMID- 27708430 TI - Unravelling the Efficient Photocatalytic Activity of Boron-induced Ti3+ Species in the Surface Layer of TiO2. AB - Ti3+ species are highly unstable in air owing to their facile oxidation into Ti4+ species, and thus they cannot concentrate in the surface layer of TiO2 but are mainly present in its bulk. We report generation of abundant and stable Ti3+ species in the surface layer of TiO2 by boron doping for efficient utilization of solar irradiation. The resultant photocatalysts (denoted as B-TiO2-x) exhibit extremely high and stable solar-driven photocatalytic activity toward hydrogen production. The origin of the solar-light activity enhancement in the B-TiO2-x photocatalysts has been thoroughly investigated by various experimental techniques and density functional theory (DFT) calculations. The unique structure invoked by presence of sufficient interstitial boron atoms can lead to substantial variations in density of states of B-TiO2-x, which not only significantly narrow the band gap of TiO2 to improve its visible-light absorption, but also promote the photogenerated electron mobility to enhance its solar-light photocatalytic activity. PMID- 27708429 TI - Structural basis for PPAR partial or full activation revealed by a novel ligand binding mode. AB - The peroxisome proliferator-activated receptors (PPARs) are nuclear receptors involved in the regulation of the metabolic homeostasis and therefore represent valuable therapeutic targets for the treatment of metabolic diseases. The development of more balanced drugs interacting with PPARs, devoid of the side effects showed by the currently marketed PPARgamma full agonists, is considered the major challenge for the pharmaceutical companies. Here we present a structure based virtual screening approach that let us identify a novel PPAR pan-agonist with a very attractive activity profile and its crystal structure in the complex with PPARalpha and PPARgamma, respectively. In PPARalpha this ligand occupies a new pocket whose filling is allowed by the ligand-induced switching of the F273 side chain from a closed to an open conformation. The comparison between this pocket and the corresponding cavity in PPARgamma provides a rationale for the different activation of the ligand towards PPARalpha and PPARgamma, suggesting a novel basis for ligand design. PMID- 27708428 TI - GSF2 deletion increases lactic acid production by alleviating glucose repression in Saccharomyces cerevisiae. AB - Improving lactic acid (LA) tolerance is important for cost-effective microbial production of LA under acidic fermentation conditions. Previously, we generated LA-tolerant D-LA-producing S. cerevisiae strain JHY5310 by laboratory adaptive evolution of JHY5210. In this study, we performed whole genome sequencing of JHY5310, identifying four loss-of-function mutations in GSF2, SYN8, STM1, and SIF2 genes, which are responsible for the LA tolerance of JHY5310. Among the mutations, a nonsense mutation in GSF2 was identified as the major contributor to the improved LA tolerance and LA production in JHY5310. Deletion of GSF2 in the parental strain JHY5210 significantly improved glucose uptake and D-LA production levels, while derepressing glucose-repressed genes including genes involved in the respiratory pathway. Therefore, more efficient generation of ATP and NAD+ via respiration might rescue the growth defects of the LA-producing strain, where ATP depletion through extensive export of lactate and proton is one of major reasons for the impaired growth. Accordingly, alleviation of glucose repression by deleting MIG1 or HXK2 in JHY5210 also improved D-LA production. GSF2 deletion could be applied to various bioprocesses where increasing biomass yield or respiratory flux is desirable. PMID- 27708431 TI - Attenuation of synaptic toxicity and MARK4/PAR1-mediated Tau phosphorylation by methylene blue for Alzheimer's disease treatment. AB - Alzheimer's disease (AD) is a neurodegenerative disease characterized by genotypic and phenotypic heterogeneity. Critical components of the two AD pathological pathways, Abeta-amyloidosis and Tauopathy, have been considered as therapeutic targets. Among them, much effort is focused on aberrant Tau phosphorylation and targeting Tau-phosphorylating kinases. Methylene blue (MB), a phenothiazine dye that crosses the blood-brain barrier, has been shown to hit multiple molecular targets involved in AD and have beneficial effects in clinical studies. Here we present evidence that microtubule affinity-regulating kinase (MARK4) is a novel target of MB. MB partially rescued the synaptic toxicity in Drosophila larva overexpressing PAR1 (MARK analog). In 293T culture, MB decreased MARK4-mediated Tau phosphorylation in a dose dependent manner. Further studies revealed a two-fold mechanism by MB including down-regulation of MARK4 protein level through ubiquitin-proteasome pathway and inhibition of MARK4 kinase activity in vitro. This study highlights the importance of MARK4 as a viable target for Tauopathy and provides fresh insight into the complex mechanism used by MB to treat AD. PMID- 27708432 TI - Hypothalamic sensing of ketone bodies after prolonged cerebral exposure leads to metabolic control dysregulation. AB - Ketone bodies have been shown to transiently stimulate food intake and modify energy homeostasis regulatory systems following cerebral infusion for a moderate period of time (<6 hours). As ketone bodies are usually enhanced during episodes of fasting, this effect might correspond to a physiological regulation. In contrast, ketone bodies levels remain elevated for prolonged periods during obesity, and thus could play an important role in the development of this pathology. In order to understand this transition, ketone bodies were infused through a catheter inserted in the carotid to directly stimulate the brain for a period of 24 hours. Food ingested and blood circulating parameters involved in metabolic control as well as glucose homeostasis were determined. Results show that ketone bodies infusion for 24 hours increased food intake associated with a stimulation of hypothalamic orexigenic neuropeptides. Moreover, insulinemia was increased and caused a decrease in glucose production despite an increased resistance to insulin. The present study confirms that ketone bodies reaching the brain stimulates food intake. Moreover, we provide evidence that a prolonged hyperketonemia leads to a dysregulation of energy homeostasis control mechanisms. Finally, this study shows that brain exposure to ketone bodies alters insulin signaling and consequently glucose homeostasis. PMID- 27708434 TI - Clinical Relevance and Molecular Phenotypes in Gastric Cancer, of TP53 Mutations and Gene Expressions, in Combination With Other Gene Mutations. AB - While altered TP53 is the most frequent mutation in gastric cancer (GC), its association with molecular or clinical phenotypes (e.g., overall survival, disease-free survival) remains little known. To that end, we can use genome-wide approaches to identify altered genes significantly related to mutated TP53. Here, we identified significant differences in clinical outcomes, as well as in molecular phenotypes, across specific GC tumor subpopulations, when combining TP53 with other signaling networks, including WNT and its related genes NRXN1, CTNNB1, SLITRK5, NCOR2, RYR1, GPR112, MLL3, MTUS2, and MYH6. Moreover, specific GC subpopulations indicated by dual mutation of NRXN1 and TP53 suggest different drug responses, according to the Connectivity Map, a pharmacological drug-gene association tool. Overall, TP53 mutation status in GC is significantly relevant to clinical or molecular categories. Thus, our approach can potentially provide a patient stratification strategy by dissecting previously unknown multiple TP53 mutated patient groups.

Here, we describe results of IgG-epitome decoding of three proteins from high-risk (HR-) oncogenic human papillomavirus type 58 (HPV58). To reveal their entire epitomes, employing peptide biosynthetic approach, 30 precise linear B-cell epitopes (BCEs) were mapped on E6, E7 and L1 proteins using rabbits antisera to the respective recombinant proteins. Using sequence alignment based on BCE minimal motif, the specificity and conservativeness of each mapped BCE were delineated mainly among known HR-HPVs, including finding 3 broadly antibody cross-reactive BCEs of L1 that each covers almost all HR-HPVs. Western blots revealed that 13 of the 18 BCEs within L1-epitome were recognized by murine antisera to HPV58 virus-like particles, suggesting that these are antibody accessible BCEs. Also, a highly conserved epitope (YGD/XTL) of E6 was found to exist only in known common HR HPVs, which could be used as the first peptide reference marker for judging HR HPVs. Altogether, this study provides systemic and exhaustive information on linear BCEs of HR-HPV58 that will facilitate development of novel multi-epitope diagnostic reagents/chips for testing viral antibodies and 'universal' preventive HPV peptide vaccine based on L1 conserved BCEs.

AB - CONTEXT: Barnard B1b has revealed as one of the most interesting globules from the chemical and dynamical point of view. It presents a rich molecular chemistry characterized by large abundances of deuterated and complex molecules. Furthermore, it hosts an extremely young Class 0 object and one candidate to First Hydrostatic Core (FHSC) proving the youth of this star forming region. AIMS: Our aim is to determine the cosmic ray ionization rate, [Formula: see text], and the depletion factors in this extremely young star forming region. These parameteres determine the dynamical evolution of the core. METHODS: We carried out a spectral survey towards Barnard 1b as part of the IRAM Large program ASAI using the IRAM 30-m telescope at Pico Veleta (Spain). This provided a very complete inventory of neutral and ionic C-, N- and S- bearing species with, up to our knowledge, the first secure detections of the deuterated ions DCS+ and DOCO+. We use a state-of-the-art pseudo-time-dependent gas-phase chemical model that includes the ortho and para forms of [Formula: see text] and [Formula: see text] to determine the local value of the cosmic ray ionization rate and the depletion factors. RESULTS: Our model assumes n(H2)=105 cm-3 and T k =12 K, as derived from our previous works. The observational data are well fitted with zetaH2 between 3*10-17 s-1 and 10-16 s-1, and the following elemental abundances: O/H=3 10-5, N/H=6.4-8 10-5, C/H=1.7 10-5 and S/H between 6.0 10-7 and 1.0 10-6. The large number of neutral/protonated species detected, allows us to derive the elemental abundances and cosmic ray ionization rate simultaneously. Elemental depletions are estimated to be ~10 for C and O, ~1 for N and ~25 for S. CONCLUSIONS: Barnard B1b presents similar depletions of C and O than those measured in pre-stellar cores. The depletion of sulfur is higher than that of C and O but not as extreme as in cold cores. In fact, it is similar to the values found in some bipolar outflows, hot cores and photon-dominated regions. Several scenarios are discussed to account for these peculiar abundances. We propose that it is the consequence of the initial conditions (important outflows and enhanced UV fields in the surroundings) and a rapid collapse (~0.1 Myr) that permits to maintain most S- and N-bearing species in gas phase to great optical depths. The interaction of the compact outflow associated with B1b-S with the surrounding material could enhance the abundances of S-bearing molecules, as well.

PMID- 27708448 TI - Diagnostic value of creatine kinase activity in canine cerebrospinal fluid. AB - This study aimed to determine whether creatine kinase (CK) activity in cerebrospinal fluid (CSF) has diagnostic value for various groups of neurological conditions or for different anatomical areas of the nervous system (NS). The age, breed, results of CSF analysis, and diagnosis of 578 canine patients presenting with various neurological conditions between January 2009 and February 2015 were retrospectively collected. The cases were divided according to anatomical areas of the nervous system, i.e., brain, spinal cord, and peripheral nervous system, and into groups according to the nature of the condition diagnosed: vascular, immune/inflammatory/infectious, traumatic, toxic, anomalous, metabolic, idiopathic, neoplastic, and degenerative. Statistical analysis showed that CSF-CK alone cannot be used as a diagnostic tool and that total proteins in the CSF and red blood cells (RBCs) do not have a significant relationship with the CSF-CK activity. CSF-CK did not have a diagnostic value for different disease groups or anatomical areas of the nervous system.

AB - This retrospective study assesses postoperative complications with simultaneous staphylectomy and unilateral arytenoid lateralization (SP + UAL) in dogs with laryngeal paralysis and concurrent elongation of the soft palate compared to dogs having a UAL alone. Medical records of dogs having a UAL performed from 2010 to 2013 were reviewed. Twenty-three dogs were diagnosed with a concurrent elongated soft palate and had a SP + UAL performed and 89 dogs were diagnosed with an appropriate soft palate and had only a UAL performed. A telephone questionnaire for long-term postoperative outcomes was completed. Survival probability was not statistically different between the 2 groups. Dogs in the SP + UAL group were more likely to be seen for respiratory distress after surgery (P = 0.05). There was no significant difference between the 2 groups in the number of dogs which developed postoperative aspiration pneumonia. The overall complication rate for both groups was high, with postoperative pneumonia being the most common complication. PMID- 27708451 TI - A perspective from 10 years of practice.

PMID- 27708454 TI - Assessing the effects of repeated handling on the physiology and condition of semi-precocial nestlings. AB - Repeated exposure to elevated levels of glucocorticoids during development can have long-term detrimental effects on survival and fitness, potentially associated with increased telomere attrition. Nestling birds are regularly handled for ecological research, yet few authors have considered the potential for handling-induced stress to influence hormonally mediated phenotypic development or bias interpretations of subsequent focal measurements. We experimentally manipulated the handling experience of the semi-precocial nestlings of European Storm Petrel Hydrobates pelagicus to simulate handling in a typical field study and examined cumulative effects on physiology and condition in late postnatal development. Neither baseline corticosterone (the primary glucocorticoid in birds), telomere length nor body condition varied with the number of handling episodes. The absence of a response could be explained if Storm Petrels did not perceive handling to be stressful or if there is dissociation of the hypothalamic-pituitary-adrenal axis from stressful stimuli in early life. Eliciting a response to a stressor may be maladaptive for cavity dwelling young that are unable to escape or defend themselves. Furthermore, avoiding elevated overall glucocorticoid exposure may be particularly important in a long-lived species, in which accelerated early-life telomere erosion could impact negatively upon longevity. We propose that the level of colony-wide disturbance induced by investigator handling of young could be important in underlining species-specific responses. Storm Petrel nestlings appear unresponsive to investigator handling within the limits of handling in a typical field study and handling at this level should not bias physiological and morphological measurements. PMID- 27708455 TI - Regional surnames and genetic structure in Great Britain. AB - Following the increasing availability of DNA-sequenced data, the genetic structure of populations can now be inferred and studied in unprecedented detail. Across social science, this innovation is shaping new bio-social research agendas, attracting substantial investment in the collection of genetic, biological and social data for large population samples. Yet genetic samples are special because the precise populations that they represent are uncertain and ill defined. Unlike most social surveys, a genetic sample's representativeness of the population cannot be established by conventional procedures of statistical inference, and the implications for population-wide generalisations about bio social phenomena are little understood. In this paper, we seek to address these problems by linking surname data to a censored and geographically uneven sample of DNA scans, collected for the People of the British Isles study. Based on a combination of global and local spatial correspondence measures, we identify eight regions in Great Britain that are most likely to represent the geography of genetic structure of Great Britain's long-settled population. We discuss the implications of this regionalisation for bio-social investigations. We conclude that, as the often highly selective collection of DNA and biomarkers becomes a more common practice, geography is crucial to understanding variation in genetic information within diverse populations. PMID- 27708456 TI - The importance of realistic dispersal models in conservation planning: application of a novel modelling platform to evaluate management scenarios in an Afrotropical biodiversity hotspot. AB - As biodiversity hotspots are often characterized by high human population densities, implementation of conservation management practices that focus only on the protection and enlargement of pristine habitats is potentially unrealistic. An alternative approach to curb species extinction risk involves improving connectivity among existing habitat patches. However, evaluation of spatially explicit management strategies is challenging, as predictive models must account for the process of dispersal, which is difficult in terms of both empirical data collection and modelling.Here, we use a novel, individual-based modelling platform that couples demographic and mechanistic dispersal models to evaluate the effectiveness of realistic management scenarios tailored to conserve forest birds in a highly fragmented biodiversity hotspot. Scenario performance is evaluated based on the spatial population dynamics of a well-studied forest bird species.The largest population increase was predicted to occur under scenarios increasing habitat area. However, the effectiveness was sensitive to spatial planning. Compared to adding one large patch to the habitat network, adding several small patches yielded mixed benefits: although overall population sizes increased, specific newly created patches acted as dispersal sinks, which compromised population persistence in some existing patches. Increasing matrix connectivity by the creation of stepping stones is likely to result in enhanced dispersal success and occupancy of smaller patches. Synthesis and applications. We show that the effectiveness of spatial management is strongly driven by patterns of individual dispersal across landscapes. For species conservation planning, we advocate the use of models that incorporate adequate realism in demography and, particularly, in dispersal behaviours. PMID- 27708457 TI - Type of fitness cost influences the rate of evolution of resistance to transgenic Bt crops. AB - The evolution of resistance to pesticides by insect pests is a significant challenge for sustainable agriculture. For transgenic crops expressing Bacillus thuringiensis (Bt), crystalline (Cry) toxins resistance evolution may be delayed by the high-dose/refuge strategy in which a non-toxic refuge is planted to promote the survival of susceptible insects. The high-dose/refuge strategy may interact with fitness costs associated with resistance alleles to further delay resistance. However, while a diverse range of fitness costs are reported in the field, they are typically represented as a fixed reduction in survival or viability which is insensitive to ecological conditions such as competition. Furthermore, the potential dynamic consequences of restricting susceptible insects to a refuge which represents only a fraction of the available space have rarely been considered.We present a generalized discrete time model which utilizes dynamic programming methods to derive the optimal management decisions for the control of a theoretical insect pest population exposed to Bt crops. We consider three genotypes (susceptible homozygotes, resistant homozygotes and heterozygotes) and implement fitness costs of resistance to Bt toxins as either a decrease in the relative competitive ability of resistant insects or as a penalty on fecundity. Model analysis is repeated and contrasted for two types of density dependence: uniform density dependence which operates equally across the landscape and heterogeneous density dependence where the intensity of competition scales inversely with patch size and is determined separately for the refuge and Bt crop.When the planting of Bt is decided optimally, fitness costs to fecundity allow for the planting of larger areas of Bt crops than equivalent fitness costs that reduce the competitive ability of resistant insects.Heterogeneous competition only influenced model predictions when the proportional area of Bt planted in each season was decided optimally and resistance was not recessive. Synthesis and applications. The high-dose/refuge strategy alone is insufficient to preserve susceptibility to transgenic Bacillus thuringiensis (Bt) crops in the long term when constraints upon the evolution of resistance are not insurmountable. Fitness costs may enhance the delaying effect of the refuge, but the extent to which they do so depends upon how the cost is realized biologically. Fitness costs which apply independently of other variables may be more beneficial to resistance management than costs which are only visible to selection under a limited range of ecological conditions. PMID- 27708458 TI - RAFT Dispersion Alternating Copolymerization of Styrene with N-Phenylmaleimide: Morphology Control and Application as an Aqueous Foam Stabilizer. AB - We report a new nonaqueous polymerization-induced self-assembly (PISA) formulation based on the reversible addition-fragmentation chain transfer (RAFT) dispersion alternating copolymerization of styrene with N-phenylmaleimide using a nonionic poly(N,N-dimethylacrylamide) stabilizer in a 50/50 w/w ethanol/methyl ethyl ketone (MEK) mixture. The MEK cosolvent is significantly less toxic than the 1,4-dioxane cosolvent reported previously [Yang P.; Macromolecules2013, 46, 8545-8556]. The core-forming alternating copolymer block has a relatively high glass transition temperature (Tg), which leads to vesicular morphologies being observed during PISA, as well as the more typical sphere and worm phases. Each of these copolymer morphologies has been characterized by transmission electron microscopy (TEM) and small-angle X-ray scattering (SAXS) studies. TEM studies reveal micrometer-sized elliptical particles with internal structure, with SAXS analysis suggesting an oligolamellar vesicle morphology. This structure differs from that previously reported for a closely related PISA formulation utilizing a poly(methacrylic acid) stabilizer block for which unilamellar platelet-like particles are observed by TEM and SAXS. This suggests that interlamellar interactions are governed by the nature of the steric stabilizer layer. Moreover, using the MEK cosolvent also enables access to a unilamellar vesicular morphology, despite the high Tg of the alternating copolymer core-forming block. This was achieved by simply conducting the PISA synthesis at a higher temperature for a longer reaction time (80 degrees C for 24 h). Presumably, MEK solvates the core-forming block more than the previously utilized 1,4-dioxane cosolvent, which leads to greater chain mobility. Finally, preliminary experiments indicate that the worms are much more efficient stabilizers for aqueous foams than either the spheres or the oligolamellar elliptical vesicles. PMID- 27708459 TI - Dose and number of applications that maximize fungicide effective life exemplified by Zymoseptoria tritici on wheat - a model analysis. AB - Two key decisions that need to be taken about a fungicide treatment programme are (i) the number of applications that should be used per crop growing season, and (ii) the dosage that should be used in each application. There are two opposing considerations, with control efficacy improved by a higher number of applications and higher dose, and resistance management improved by a lower number of applications and lower dose. Resistance management aims to prolong the effective life of the fungicide, defined as the time between its introduction onto the market for use on the target pathogen, and the moment when effective control is lost due to a build-up of fungicide resistance. Thus, the question is whether there are optimal combinations of dose rate and number of applications that both provide effective control and lead to a longer effective life. In this paper, it is shown how a range of spray programmes can be compared and optimal programmes selected. This is explored with Zymoseptoria tritici on wheat and a quinone outside inhibitor (QoI) fungicide. For this pathogen-fungicide combination, a single treatment provided effective control under the simulated disease pressure, but only if the application timing was optimal and the dose was close to the maximum permitted. Programmes with three applications were generally not optimal as they exerted too much selection for resistance. Two-application fungicide programmes balanced effective control with reasonable flexibility of dose and application timing, and low resistance selection, leading to long effective lives of the fungicide. PMID- 27708460 TI - Respectability, morality and disgust in the night-time economy: exploring reactions to 'lap dance' clubs in England and Wales. AB - The night-time economy is often described as repelling consumers fearful of the 'undesirable Others' imagined dominant within such time-spaces. In this paper we explore this by describing attitudes towards, and reactions to, one particularly contentious site: the 'lap dance' club. Often targeted by campaigners in England and Wales as a source of criminality and anti-sociality, in this paper we shift the focus from fear to disgust, and argue that Sexual Entertainment Venues (SEVs) are opposed on the basis of moral judgments that reflect distinctions of both class and gender. Drawing on documentary analysis, survey results and interview data collected during guided walks, we detail the concerns voiced by those anxious about the presence of lap dance or striptease clubs in their town or city, particularly the notion that they 'lower the tone' of particular streets or neighbourhoods. Our conclusion is that the opposition expressed to lap dance clubs is part of an attempt to police the boundaries of respectable masculinities and femininities, marginalizing the producers and consumers of sexual entertainment through 'speech acts' which identify such entertainment as unruly, vulgar and uncivilized. These findings are considered in the light of ongoing debates concerning the relations of morality, respectability and disgust. PMID- 27708461 TI - Ethical boundary-work in the animal research laboratory. AB - The use of animals in scientific experiments continues to attract significant controversy, particularly in the UK. This article draws on in-depth interviews with senior laboratory scientists who use animals in their research. A key claim is that animal research is necessary for medical advance. However, this promissory discourse relies on the construction of three boundaries. The first is between humans and non-human animals. The second is between the positive and less positive impacts of Home Office regulation. The third is between the use of animals in medicine versus other domains such as farming. The article analyses these discourses and evaluates the applicability of 'ethical boundary-work' (Wainwright et al., 2006a). I conclude that the concept is a potentially useful device for foregrounding ethics but argue that it carries several dangers for sociologists interested in claim-making in areas of controversy. PMID- 27708462 TI - Antileukemic alpha-pyrone derivatives from the endophytic fungus Alternaria phragmospora. AB - Four new (1-4) and two known (5 and 6) alpha-pyrone derivatives have been isolated from Alternaria phragmospora, an endophytic fungus from Vinca rosea, leaves. The isolated compounds were chemically identified to be 5-butyl-4-methoxy 6-methyl-2H-pyran-2-one (1), 5-butyl-6-(hydroxymethyl)-4-methoxy-2H-pyran-2-one (2), 5-(1-hydroxybutyl)-4-methoxy-6-methyl-2H-pyran-2-one (3), 4-methoxy-6-methyl 5-(3-oxobutyl)-2H-pyran-2-one (4), 5-(2-hydroxyethyl)-4-methoxy-6-methyl-2H-pyran 2-one (5), and 5-[(2E)-but-2-en-1-yl]-4-methoxy-6-methyl-2H-pyran-2-one (6). Compounds 2 and 4 showed moderate antileukemic activities against HL60 cells with IC50 values of 2.2 and 0.9 MUM and against K562 cells with IC50 values of 4.5 and 1.5 MUM, respectively.

PMID- 27708469 TI - Inpatient management of children with severe acute malnutrition: a review of WHO guidelines. AB - OBJECTIVE: To understand how the World Health Organization's (WHO's) guidelines on the inpatient care of children with complicated severe acute malnutrition may be strengthened to improve outcomes. METHODS: In December 2015, we searched Google scholar and WHO's website for WHO recommendations on severe acute malnutrition management and evaluated the history and cited evidence behind these recommendations. We systematically searched WHO International Clinical Trials Registry Platform, clinicaltrials.gov and the Controlled Trials metaRegister until 10 August 2015 for recently completed, ongoing, or pending trials. FINDINGS: WHO's guidelines provide 33 recommendations on the topic. However, 16 (48.5%) of these recommendations were based solely on expert opinion - unsupported by published evidence. Another 11 (33.3%) of the recommendations were supported by the results of directly relevant research - i.e. either randomized trials (8) or observational studies (3). The other six recommendations (18.2%) were based on studies that were not conducted among children with complicated severe malnutrition or studies of treatment that were not identical to the recommended intervention. Trials registries included 20 studies related to the topic, including nine trials of alternative feeding regimens. Acute medical management and follow-up care studies were minimally represented. CONCLUSION: WHO's guidelines on the topic have a weak evidence base and have undergone limited substantive adjustments over the past decades. More trials are needed to make that evidence base more robust. If the mortality associated with severe malnutrition is to be reduced, inpatient and post-discharge management trials, supported by studies on the causes of mortality, are needed. PMID- 27708471 TI - Gang truce for violence prevention, El Salvador. AB - OBJECTIVE: To estimate the effects on homicide rates of the gang truce that was brokered in El Salvador in 2012. METHODS: Mathematical models based on municipal level census, crime and gang-intelligence data were used to estimate the effect of the truce on homicide rates. One model estimated the overall effect after accounting for the linear trend and seasonality in the homicide rate. In a moderated-effect model, we investigated the relationship between the truce effect and the numbers of MS13 (Mara Salvatrucha 13) and Eighteenth-Street gang members imprisoned per 100 000 population. We then ran each of these two models with additional control variables. We compared values before the truce - 1 January 2010 to 29 February 2012 - with those after the truce - 1 March 2012 to 31 December 2013. FINDINGS: The overall-effect models with and without additional control variables indicated a homicide rate after the truce that was significantly lower than the value before the truce, giving rate ratios of 0.55 (95% confidence interval, CI: 0.49-0.63) and 0.61 (95% CI: 0.54-0.69), respectively. For any given municipality, the effectiveness of the truce appeared to increase as the number of MS13 gang members imprisoned per 100 000 population increased. We did not observe the same significant relationship for imprisoned Eighteenth-Street gang members. CONCLUSION: In the 22 months following the establishment of a national gang truce, the homicide rate was about 40% lower than in the preceding 26 months. The truce's impact appeared particularly strong in municipalities with relatively high numbers of imprisoned MS13 gang members per 100 000 population. PMID- 27708470 TI - Visual health screening by schoolteachers in remote communities of Peru: implementation research. AB - OBJECTIVE: To describe the adaptation and scaling-up of an intervention to improve the visual health of children in the Apurimac region, Peru. METHODS: In a pilot screening programme in 2009-2010, 26 schoolteachers were trained to detect and refer visual acuity problems in schoolchildren in one district in Apurimac. To scale-up the intervention, lessons learnt from the pilot were used to design strategies for: (i) strengthening multisector partnerships; (ii) promoting the engagement and participation of teachers and (iii) increasing children's attendance at referral eye clinics. Implementation began in February 2015 in two out of eight provinces of Apurimac, including hard-to-reach communities. We made an observational study of the processes and outcomes of adapting and scaling-up the intervention. Qualitative and quantitative analyses were made of data collected from March 2015 to January 2016 from programme documents, routine reports and structured evaluation questionnaires completed by teachers. FINDINGS: Partnerships were expanded after sharing the results of the pilot phase. Training was completed by 355 teachers and directors in both provinces, belonging to 315 schools distributed in 24 districts. Teachers' appraisal of the training achieved high positive scores. Outreach eye clinics and subsidies for glasses were provided for poorer families. Data from six districts showed that attendance at the eye clinic increased from 66% (45/68 children referred) in the pilot phase to 92% (237/259) in the implementation phase. CONCLUSION: Adaptation to the local context allowed the scaling-up of an intervention to improve visual health in children and enhanced the equity of the programme. PMID- 27708472 TI - A retrospective analysis of oral cholera vaccine use, disease severity and deaths during an outbreak in South Sudan. AB - OBJECTIVE: To determine whether pre-emptive oral cholera vaccination reduces disease severity and mortality in people who develop cholera disease during an outbreak. METHODS: The study involved a retrospective analysis of demographic and clinical data from 41 cholera treatment facilities in South Sudan on patients who developed cholera disease between 23 April and 20 July 2014 during a large outbreak, a few months after a pre-emptive oral vaccination campaign. Patients who developed severe dehydration were regarded as having a severe cholera infection. Vaccinated and unvaccinated patients were compared and multivariate logistic regression analysis was used to identify factors associated with developing severe disease or death. FINDINGS: In total, 4115 cholera patients were treated at the 41 facilities: 1946 (47.3%) had severe disease and 62 (1.5%) deaths occurred. Multivariate analysis showed that patients who received two doses of oral cholera vaccine were 4.5-fold less likely to develop severe disease than unvaccinated patients (adjusted odds ratio, aOR: 0.22; 95% confidence interval, CI: 0.11-0.44). Moreover, those with severe cholera were significantly more likely to die than those without (aOR: 4.76; 95% CI: 2.33-9.77). CONCLUSION: Pre-emptive vaccination with two doses of oral cholera vaccine was associated with a significant reduction in the likelihood of developing severe cholera disease during an outbreak in South Sudan. Moreover, severe disease was the strongest predictor of death. Two doses of oral cholera vaccine should be used in emergencies to reduce the disease burden. PMID- 27708473 TI - Zika: the origin and spread of a mosquito-borne virus. AB - OBJECTIVE: To describe the temporal and geographical distribution of Zika virus infection and associated neurological disorders, from 1947 to 1 February 2016, when Zika became a Public Health Emergency of International Concern (PHEIC). METHODS: We did a literature search using the terms "Zika" and "ZIKV" in PubMed, cross-checked the findings for completeness against other published reviews and added formal notifications to WHO submitted under the International Health Regulations. FINDINGS: From the discovery of Zika virus in Uganda in 1947 to the declaration of a PHEIC by the World Health Organization (WHO) on 1 February 2016, a total of 74 countries and territories had reported human Zika virus infections. The timeline in this paper charts the discovery of the virus (1947), its isolation from mosquitos (1948), the first human infection (1952), the initial spread of infection from Asia to a Pacific island (2007), the first known instance of sexual transmission (2008), reports of Guillain-Barre syndrome (2014) and microcephaly (2015) linked to Zika infections and the first appearance of Zika in the Americas (from 2015). CONCLUSION: Zika virus infection in humans appears to have changed in character as its geographical range has expanded from equatorial Africa and Asia. The change is from an endemic, mosquito-borne infection causing mild illness to one that can cause large outbreaks linked with neurological sequelae and congenital abnormalities. PMID- 27708474 TI - The International Finance Facility for Immunisation: stakeholders' perspectives. AB - OBJECTIVE: To evaluate stakeholders' understanding and opinions of the International Finance Facility for Immunisation (IFFIm); to identify factors affecting funding levels; and to explore the future use of IFFIm. METHODS: Between July and September 2015, we interviewed 33 individuals from 25 organizations identified as stakeholders in IFFIm. In total 22.5 hours of semi structured interviews were recorded, transcribed and analysed using a framework method. FINDINGS: Stakeholders' understanding of IFFIm's financing mechanism and its outcomes varied and many stakeholders wanted more information. Participants highlighted that the change in the macro-economic environment following the 2008 financial crisis affected national policy in donor countries and subsequently the number of new commitments IFFIm received. Since Gavi is now seen as a successful and mature organization, participants stated that donors prefer to donate directly to Gavi. The pharmaceutical industry valued IFFIm for providing funding stability and flexibility. Other stakeholders valued IFFIm's ability to access funds early and enable Gavi to increase vaccine coverage. Overall, stakeholders thought IFFIm was successful, but they had divergent views about IFFIm's on-going role. Participants listed two issues where bond financing mechanisms may be suitable: emergency preparedness and outcome-based time-limited interventions. CONCLUSION: The benefit of pledging funds through IFFIm needs to be re-evaluated. There are potential uses for bond financing to raise funds for other global health issues, but these must be carefully considered against criteria to establish effectiveness, with quantifiable pre-defined outcome indicators to evaluate performance.

PMID- 27708475 TI - Group-based microfinance for collective empowerment: a systematic review of health impacts. AB - OBJECTIVE: To assess the impact on health-related outcomes, of group microfinance schemes based on collective empowerment. METHODS: We searched the databases Social Sciences Citation Index, Embase, MEDLINE, MEDLINE In-Process, PsycINFO, Social Policy & Practice and Conference Proceedings Citation Index for articles published between 1 January 1980 and 29 February 2016. Articles reporting on health impacts associated with group-based microfinance were included in a narrative synthesis. FINDINGS: We identified one cluster-randomized control trial and 22 quasi-experimental studies. All of the included interventions targeted poor women living in low- or middle-income countries. Some included a health promotion component. The results of the higher quality studies indicated an association between membership of a microfinance scheme and improvements in the health of women and their children. The observed improvements included reduced maternal and infant mortality, better sexual health and, in some cases, lower levels of interpersonal violence. According to the results of the few studies in which changes in empowerment were measured, membership of the relatively large and well-established microfinance schemes generally led to increased empowerment but this did not necessarily translate into improved health outcomes. Qualitative evidence suggested that increased empowerment may have contributed to observed improvements in contraceptive use and mental well-being and reductions in the risk of violence from an intimate partner. CONCLUSION: Membership of the larger, well-established group-based microfinance schemes is associated with improvements in some health outcomes. Future studies need to be designed to cope better with bias and to assess negative as well as positive social and health impacts. PMID- 27708478 TI - Soil acidification and the importance of liming agricultural soils with particular reference to the United Kingdom. AB - Soil acidification is caused by a number of factors including acidic precipitation and the deposition from the atmosphere of acidifying gases or particles, such as sulphur dioxide, ammonia and nitric acid. The most important causes of soil acidification on agricultural land, however, are the application of ammonium-based fertilizers and urea, elemental S fertilizer and the growth of legumes. Acidification causes the loss of base cations, an increase in aluminium saturation and a decline in crop yields; severe acidification can cause nonreversible clay mineral dissolution and a reduction in cation exchange capacity, accompanied by structural deterioration. Soil acidity is ameliorated by applying lime or other acid-neutralizing materials. 'Liming' also reduces N2O emissions, but this is more than offset by CO 2 emissions from the lime as it neutralizes acidity. Because crop plants vary in their tolerance to acidity and plant nutrients have different optimal pH ranges, target soil pH values in the UK are set at 6.5 (5.8 in peaty soils) for cropped land and 6.0 (5.3 in peaty soils) for grassland. Agricultural lime products can be sold as 'EC Fertiliser Liming Materials' but, although vital for soil quality and agricultural production, liming tends to be strongly influenced by the economics of farming. Consequently, much less lime is being applied in the UK than required, and many arable and grassland soils are below optimum pH. PMID- 27708477 TI - Assessment of a numerical model to reproduce event-scale erosion and deposition distributions in a braided river. AB - Numerical morphological modeling of braided rivers, using a physics-based approach, is increasingly used as a technique to explore controls on river pattern and, from an applied perspective, to simulate the impact of channel modifications. This paper assesses a depth-averaged nonuniform sediment model (Delft3D) to predict the morphodynamics of a 2.5 km long reach of the braided Rees River, New Zealand, during a single high-flow event. Evaluation of model performance primarily focused upon using high-resolution Digital Elevation Models (DEMs) of Difference, derived from a fusion of terrestrial laser scanning and optical empirical bathymetric mapping, to compare observed and predicted patterns of erosion and deposition and reach-scale sediment budgets. For the calibrated model, this was supplemented with planform metrics (e.g., braiding intensity). Extensive sensitivity analysis of model functions and parameters was executed, including consideration of numerical scheme for bed load component calculations, hydraulics, bed composition, bed load transport and bed slope effects, bank erosion, and frequency of calculations. Total predicted volumes of erosion and deposition corresponded well to those observed. The difference between predicted and observed volumes of erosion was less than the factor of two that characterizes the accuracy of the Gaeuman et al. bed load transport formula. Grain size distributions were best represented using two phi intervals. For unsteady flows, results were sensitive to the morphological time scale factor. The approach of comparing observed and predicted morphological sediment budgets shows the value of using natural experiment data sets for model testing. Sensitivity results are transferable to guide Delft3D applications to other rivers. PMID- 27708479 TI - Predictors of shell size in long-lived lake gastropods. AB - AIM: To investigate shell size variation among gastropod faunas of fossil and recent long-lived European lakes and discuss potential underlying processes. LOCATION: Twenty-three long-lived lakes of the Miocene to Recent of Europe. METHODS: Based on a dataset of 1412 species of both fossil and extant lacustrine gastropods, we assessed differences in shell size in terms of characteristics of the faunas (species richness, degree of endemism, differences in family composition) and the lakes (surface area, latitude and longitude of lake centroid, distance to closest neighbouring lake) using multiple and linear regression models. Because of a strong species-area relationship, we used resampling to determine whether any observed correlation is driven by that relationship. RESULTS: The regression models indicated size range expansion rather than unidirectional increase or decrease as the dominant pattern of size evolution. The multiple regression models for size range and maximum and minimum size were statistically significant, while the model with mean size was not. Individual contributions and linear regressions indicated species richness and lake surface area as best predictors for size changes. Resampling analysis revealed no significant effects of species richness on the observed patterns. The correlations are comparable across families of different size classes, suggesting a general pattern. MAIN CONCLUSIONS: Among the chosen variables, species richness and lake surface area are the most robust predictors of shell size in long-lived lake gastropods. Although the most outstanding and attractive examples for size evolution in lacustrine gastropods come from lakes with extensive durations, shell size appears to be independent of the duration of the lake as well as longevity of a species. The analogue of long-lived lakes as 'evolutionary islands' does not hold for developments of shell size because different sets of parameters predict size changes. PMID- 27708480 TI - Roads and bats: a meta-analysis and review of the evidence on vehicle collisions and barrier effects. AB - Roads are a potential threat to bat conservation. In addition to the direct risk of collision of bats with vehicles, roads could pose a threat to bat populations as a result of habitat loss, degradation and fragmentation, and could act as barriers to movements of bats between habitats.We performed a systematic review of the literature and conducted meta-analyses to assess the threat posed by roads to bats as a result of 1) collisions between bats and vehicles and 2) roads acting as barriers to movements of bats.Based on collated records of 1207 bat road casualties in Europe, we found that low-flying species are more prone to collisions than high-flying species, and that juveniles are more vulnerable to collisions than adults. In addition, meta-analysis identified a significant bias towards male casualties. Casualties included rare species such as Barbastella barbastellus and geographically restricted species such as Rhinolophus species.The bias towards male casualties could be indicative of greater natal philopatry or lower dispersal among females, or of sexual segregation in habitats of varying quality, i.e. females may occupy better quality habitats than males, and road density may be lower in better quality habitats.Whether or not roads act as barriers to the movement of bats depends on a complex interplay of habitat and species-specific behaviour. For example, the presence of favourable habitat for bats - notably woodland - was found in this review to be linked with significantly reduced barrier effects but a heightened risk of collision.Our data suggest that roads do pose a threat to bats. Future research should assess the contribution of traffic noise and street lighting to the barrier effect of roads. Where new road schemes are monitored by ecological practitioners, it is vital that consistent protocols are employed to ensure that bat activity can be compared before and after the road is built. Evidence from such research should be used to minimize the risks for bats of any roads built in the future, and to design safe crossing points for bats.

Birds are considered to be the primary selective agents for warning colouration in butterflies, and select for aposematic mimicry by learning to avoid brightly coloured prey after unpleasant experiences. It has long been thought that bright colouration plays an important role in promoting the avoidance of distasteful prey by birds. 2. The hypothesis that warning colouration facilitates memorability and promotes predator avoidance was tested by means of a field experiment using distasteful model butterflies. Artificial butterflies with a Heliconius colour pattern unknown to local birds were generated using bird vision models, either coloured or achromatic, and hung in tree branches in a tropical forest. Two sequential trials were conducted at each site to test avoidance by naive and experienced predators. 3. There was a significant reduction in predation in the second trial. Also, coloured models were attacked less than achromatic models. Specifically, coloured butterflies were attacked significantly less in the second trial, but there was no significant decrease in predation on achromatic models. 4. The present results imply an important role for colour in enhancing aversion of aposematic butterflies. It has also been demonstrated that previous experience of distasteful prey can lead to enhanced avoidance in subsequent trials, supporting mimicry theory. PMID- 27708482 TI - Scientometric Dilemma: Is H-index Adequate for Scientific Validity of Academic's Work? AB - H-index is an index that attempts to measure the productivity and impact of published work of scientists. H-index has several advantages - it combines productivity with echo, is not sensitive to extreme values in terms of articles without citation or to articles with above-average number of citations and directly enables the identification of the most relevant articles with regard to the number of citations received. H-index has great potential in the academic community, but it still has not realistic indicator of the quality of work of one author. Authors described most used indices for scientific assessment. PMID- 27708483 TI - Glycated Hemoglobin (HbA1c): Clinical Applications of a Mathematical Concept. AB - BACKGROUND AND PURPOSE: Glycated hemoglobin (HbA1c) reflects the cumulative glucose exposure of erythrocytes over a preceding time frame proportional to erythrocyte survival. HbA1c is thus an areal function of the glucose-time curve, an educationally useful concept to aid teaching and clinical judgment. METHODS: An ordinary differential equation is formulated as a parsimonious model of HbA1c. The integrated form yields HbA1c as an area-under-the-curve (AUC) of a glucose time profile. The rate constant of the HbA1c model is then derived using the validated regression equation in the ADAG study that links mean blood glucose and HbA1c with a very high degree of goodness-of-fit. RESULTS: This model has didactic utility to enable patients, biomedical students and clinicians to appreciate how HbA1c may be conceptually inferred from discrete blood glucose values using continuous glucose monitoring system (CGMS) or self-monitored blood glucose (SMBG) glucometer readings as shown in the examples. It can be appreciated how hypoglycemia can occur with rapid HbA1c decline despite poor glycemic control. CONCLUSIONS: Being independent of laboratory assay pitfalls, computed 'virtual' HbA1c serves as an invaluable internal consistency cross-check against laboratory-measured HbA1c discordant with SMBG readings suggestive of inaccurate/fraudulent glucometer records or hematologic disorders including thalassemia and hemoglobinopathy. This model could be implemented within portable glucometers, CGMS devices and even smartphone apps for deriving tentative 'virtual' HbA1c from serial glucose readings as an adjunct to measured HbA1c. Such predicted 'virtual' HbA1c readily accessible via glucometers may serve as feedback to modify behavior and empower diabetic patients to achieve better glycemic control. PMID- 27708484 TI - Calcitonin Receptor AluI (rs1801197) and Taq1 Calcitonin Genes Polymorphism in 45 and Over 45-year-old Women and their Association with Bone Density. AB - PURPOSE: Calcitonin receptor gene has also a polymorphism which is associated with bone mass density. This study evaluates the association between calcitonin receptor AluI (rs1801197) and Taq1 calcitonin genes polymorphism with bone density rate. METHODS: In this descriptive-analytical study in 2013 in southwestern Iran, 200 blood samples, per the Cochran sample size formula, were taken from women aged 45 and older. DNA was extracted from the samples using the phenol- chloroform method and the genomic fragments in question were proliferated using the polymerase chain reaction (PCR) method. RESULTS: The genotypic distribution of polymorphism AluI for TT, TC, and CC genotypes in control group was 31.4%, 38.6%, and 30% and in patients 25.4%, 55.4%, and 19.2%, respectively. There was no significant difference in polymorphism AluI between patients and control group and no significant association was found between this gene and bone density rate (P > 0.05). All patients and the individuals in the control group exhibited tt genotype for TaqI calcitonin gene and no significant association was found between these participants and osteoporosis. CONCLUSION: There was no association between two polymorphisms and osteoporosis, and between polymorphism of these two genes and osteoporosis development rate in the participants. PMID- 27708485 TI - DWI/ADC in Differentiation of Benign from Malignant Focal Liver Lesion. AB - MATERIAL AND METHODS: The study was of prospective-retrospective character. It was carried out at the AKH in Vienna (Austria), where 100 patients with focal liver lesions were included in the study. All patients underwent the routine MR sequences on appliances 1,5 and 3T (Siemens, Germany): T1, T2, HASTE, VIBE, and a DWI with three b values (b 50, b 300 b 600 s / mm2) and ADC map with ROI (regions of interest). The numerical value of ADC map was calculated, where n = 100 liver lesions, by two independent radiologists. RESULTS: On the basis of matching the PH finding statistically we get DWI accuracy of 96.8% for the assessment of liver lesions. The average numerical value of ADC in benign hepatic lesions (FNH, Hemangiomas) in our study amounted to 1.88 (1.326 to 2.48) x103 mm2 /s, while the value of malignant liver lesions (HCC, CCC, CRCLM) were significantly lower and amounted to 1.15 (1.024 to 1.343) x10-3 mm2 /s (Figure 2). Differences between the mean ADC of benign and malignant lesions showed a statistically significant difference with p <0.0005. In our research, we get cut-off for the ADC value of 1,341x10-3 mm2 /s, which proved to be the optimal parameter for differentiation between benign and malignant lesions. CONCLUSION: Measuring ADC values with DWI as an additional MRI tool can help in oncological practice by distinguishing normal liver parenchyma from focal lesions, and in differentiating benign from malignant liver lesions, particularly in cases where administration of contrast is not possible. PMID- 27708486 TI - Typing of Methicillin Resistant Staphylococcus Aureus Using DNA Fingerprints by Pulsed-field Gel Electrophoresis. AB - BACKGROUND: Methicillin resistant Staphylococcus aureus (MRSA) is responsible for a wide spectrum of nosocomial and community associated infections worldwide. The aim of this study was to analyze MRSA strains from the general population in Canton Sarajevo, B&H. METHODS: Our investigation including either phenotypic and genotypic markers such as antimicrobial resistance, pulsed-field gel electrophoresis (PFGE), SCC typing, and Panton-Valentine leukocidin (PVL) detection. RESULTS: Antimicrobial susceptibility: all MRSA isolates were resistant to the beta-lactam antibiotics tested, and all isolates were susceptible trimethoprim sulphamethoxazole, rifampicin, fusidic acid, linezolid and vancomycin. Sixty-eight per cent of the MRSA isolates were resistant to erythromycin, 5% to clindamycin, 5% to gentamicin and 4% to ciprofloxacin. After the PFGE analysis, the isolates were grouped into five similarity groups: A-E. The largest number of isolates belonged to one of two groups: C: 60 (60%) and D: 27 (27%). In both groups C and D, SCCmec type IV was predominant (60% and 88, 8%, respectively). A total of 24% of the isolates had positive expression of PVL genes, while 76% showed a statistically significantly greater negative expression of PVL genes. CONCLUSION: SCCmec type IV, together with the susceptibility profile and PFGE grouping, is considered to be typical of CA-MRSA. PMID- 27708487 TI - The Use of Continuous Electrocardiographic Holter Monitoring in Pediatric Cardiology. AB - OBJECTIVE: To show the place and role of continuous electrocardiographic twenty four-hour ECG monitoring in daily clinical practice of pediatric cardiologists. METHODS: According to protocol, 2753 patients underwent dynamic continuous ECG Holter monitoring (data collected from the "Register of ECG Holter monitoring" of Pediatric Clinic, UCC Sarajevo in period April 2003- April 2015). RESULTS: There were 50,5% boys and 49,5% girls, aged from birth to 19 years (1,63% - neonates and infants, 2,6% - toddlers, 9,95% - preschool children, 35,5% - gradeschoolers and 50,3% children in puberty and adolescence). In 68,1% of patients Holter was performed for the first time.

In mentioned period 57 cases of Wolf Parkinson White syndrome were registered, in 4,5% of patients antiarrhythmic therapy was administered. Radiofrequent ablation was performed in 23 cases. CONCLUSION: The development of pediatric cardiac surgery has initiated development of pediatric arrhythmology as imperative segment of pediatric cardiology. Continuous ECG Holter monitoring has become irreplaceable method in everyday diagnostics and therapy of arrhythmias in children. PMID- 27708488 TI - Efficacy of Multidetector-Row Computed Tomography as a Practical Tool in Comparison to Invasive Procedures for Visualization of the Biliary Obstruction. AB - INTRODUCTION: Recently, multidetector computed tomography (MDCT) has been introduced into clinical practice. MDCT has become the noninvasive diagnostic test of choice for detailed evaluation of biliary obstruction. AIM: the main objective of the present study was to evaluate the diagnostic value of MDCT compared to invasive procedures for detecting biliary obstruction causes. MATERIAL AND METHODS: Since February 2009 until May 2011 fifty biliary obstruction patients based on clinical, laboratory or ultrasonographic findings, were evaluated by Multidetector-row computed tomography. The causes of biliary obstruction, which was identified using. MDCT were classified into three categories: calculus, benign stricture, and malignancy. Final diagnosis was conducted based on percutaneous transhepatic cholangiography (PTC), endoscopic retrograde cholangiopancreatography, biopsy, or surgery. The MDCT diagnosis and were compared with the final diagnosis. RESULTS: A correct diagnosis of causes of biliaryobstruction was made on the basis of MDCT findings for 44 of the total 50 patients. Two patients with chronic pancreatitis were incorrectly diagnosed with a pancreatic head adenocarcinoma on the basis of MDCT findings. One patient with biliary stone was incorrectly diagnosed with a periampullary adenocarcinoma on the basis of MDCT findings. The Sensitivity, specificity and accuracy of MDCT in the diagnosis of causes of biliary obstruction were 94.12% and87.87% and94.6% respectively. CONCLUSION: Based on the findings of this study MDCT has an excellent image quality, providing valuable information about the biliary tree and other abdominal organs. The use of advanced image processing, including maximum intensity projection and multiplanar reconstruction (especially coronal or sagittal reformatted images), allows superior visualization of the biliary tree and vascular structures. Three-dimensional reconstruction images complement axial images by providing a more anatomically meaningful display of the lesion and its relationship to adjacent structures, and accurate determining the craniocaudal extent of the lesion. High accuracy, wide availability and ease of use, make the MDCT the imaging modality of choice for evaluation of biliary obstruction.

PMID- 27708489 TI - Biomechanical Stability of Juvidur and Bone Models on Osteosyntesic Materials. AB - INTRODUCTION: Artificial models can be useful at approximate and qualitative research, which should give the preliminary results. Artificial models are usually made of photo-elastic plastic e.g.. juvidur, araldite in the three dimensional contour shape of the bone. Anatomical preparations consist of the same heterogeneous, structural materials with extremely anisotropic and unequal highly elastic characteristics, which are embedded in a complex organic structure. THE AIM OF THE STUDY: Examine the budget voltage and deformation of: dynamic compression plate (DCP), locking compression plate (LCP), Mitkovic internal fixator (MIF), Locked intramedullary nailing (LIN) on the compressive and bending forces on juvidur and veal bone models and compared the results of these two methods (juvidur, veal bone). MATERIAL AND METHODS: For the experimental study were used geometrically identical, anatomically shaped models of Juvidur and veal bones diameter of 30 mm and a length of 100 mm. Static tests were performed with SHIMADZU AGS-X testing machine, where the force of pressure (compression) increased from 0 N to 500 N, and then conducted relief. Bending forces grew from 0 N to 250 N, after which came into sharp relief. RESULTS: On models of juvidur and veal bones studies have confirmed that uniform stability at the site of the fracture MIF with a coefficient ranking KMIF=0,1971, KLIN=0,2704, KDCP=0,2727 i KLCP=0,5821. CONCLUSION: On models of juvidur and veal bones working with Shimadzu AGS-X testing machine is best demonstrated MIF with a coefficient of 0.1971. PMID- 27708491 TI - The Relation between Iranian Medical Science Research in PubMed and Burden of Disease. AB - INTRODUCTION: Scientific productions have been accelerated in Iran in past decades but its association with health problems and disease burden is doubtful. The aim of this study is assessment of the relationship between scientific productions with disease burden in Iran in PubMed dataset during 2010 to 2014. METHOD: The study was performed with the library method. Data Gathered using Scientometrics indicators and direct observation. The current research includes all articles written by Iranian researchers during 2010 to 2014 which were published in PubMed-indexed journals. The search was performed using keywords included road accident, ischaemic heart diseases, major depression disorders and cerebral vascular diseases. RESULTS: In total 910 articles had been published PubMed -indexed journals. Among them Substance-Related Disorders and Accidents, Traffic had the highest (263 records) and lowest (94 records) records respectively. There was not a direct correlation between Years of Life Lost, Years Lost due to Disability and mortality rate with scientific productions. CONCLUSIONS: our results showed Iranian scientific productions in PubMed data set are not related to disease burden however they are not related to high mortality diseases. PMID- 27708492 TI - Organism Encumbrance of Cardiac Surgeon During Surgery. AB - INTRODUCTION: Most everyday activities, performed over a long period leads to performance degradation of skeletal muscles as well as spinal column which is reflected in the reduction of maximum force, reduction of the speed of response, reducing control of the movement etc. Although until now many mathematical models of muscles are developed, very small number takes into account the fatigue, and those models that take into account changes in the characteristics of muscles for extended activities, generally considered tiring under certain conditions. Given that the current models of muscle fatigue under arbitrary conditions of activation and load are very limited, this article presents a new model that includes scale of muscles overload. MATERIAL AND METHODS: There are three female cardiac surgeons working performing these surgeries in operating rooms, and their average anthropometric measures for this population is: a) Weight: 62 kg; b) Height: 166 cm. Age: 45 taken in the calculation within the CATIA software, that entity is entitled to 50% of healthy female population that is able to execute these and similar jobs. During the surgery is investigated the two most common positions: position "1" and "2". We wish to emphasize that the experiment or surgical procedure lasted for two positions for five hours, with the position "1" lasted 0.5 hours, and position "2" lasted about 4.5 hours. The additional load arm during surgery is about 1.0 kg. RESULTS: The analysis was done in three positions: "Operating position 1", "Operating position 2 ', and each of these positions will be considered in its characteristic segments. These segments are: when the body takes the correct position, but is not yet burdened with external load, then when the surgeon receives the load and the third position when the load is lifted at the end of the position. Calculation of internal energy used on the joints is carried out in the context of software analysis of this model using CATIA R5v19. The proposed model is based on CATIA software model, which consists of visual indicators of the burden on certain parts of the body as well as the forces acting in these parts of the body. CONCLUSION: Based on these indicators to define which muscles, as well as that part of the skeletal system is overloaded, what is the position and what needs to be done that specific load be within permitted limits.

AB - BACKGROUND: This project sought to identify the most common telepathology consultation needs of pathologists based on the anatomic section of tissue to improve quality of consultations. METHODS: This cross-sectional study used a questionnaire with four questions to assess pathologists' consultation needs. The questionnaire was distributed to the 16 pathologists recruited for this study. All 16 of the pathologists work in Kerman province, the largest province of Iran, which is situated 1,000 kilometers from Tehran, Iran's capital city. RESULTS: On average, the pathologists expressed a need to consult with their colleagues in 7.5% of cases. They believed that articular and bone tissue, soft tissue and the lymphoid system (respectively in descending order) to be the three anatomical parts that require the greatest amount of consultation. As such, consultant pathologists should ensure they have particular expertise in articular and bone tissue, soft tissue and the lymphoid system. CONCLUSION: This study demonstrated that pathologists most need advice from consultants when working with samples of articular and bone tissue, soft tissue and the lymphoid system. These results can be used to ensure successful implementation of telepathology systems, which are helpful for consultation from rural and remote areas.

AB - INTRODUCTION: Positron emission tomography/computed tomography (PET-CT) is very sensitive for diagnosis of recurrent NSCLC and has a significant impact on change of management. Preliminary data suggest superiority of PET-CT comparing to CT alone for lung cancer restaging. MATERIALS AND METHODS: This is a retrospective study which aim is to validate usage of PET-CT in suspected non-small cell lung carcinoma recurrence and its impact on further patient management. Total number of 31 patients with non-small cell lung carcinoma and uncertain diagnosis of recurrent disease or its extent after routine clinical and CT work-up were enrolled in this study. DISCUSSION: We found in our study that PET-CT diagnosed recurrent disease in 65% of patients who were previously presented with an indeterminante CT. In 85% of patients there were change in further management. CONCLUSION: We suggest that PET should be performed on patients who have suspected relapse after potentially curative treatment, particularly if active treatment is being considered. PET-CT improved the diagnosis of recurrent NSCLC and this resulted in a significant impact and change in further patient management.

The purpose of present study is to review and analyze physician-physician teleconsultations. METHOD: The PubMed electronic database was searched. The primary search was done on January 2015 and was updated on December 2015. A fetch and tag plan was designed by the researchers using an online Zotero library. RESULTS: 174 full-text articles of 1702 records met inclusion criteria. Teleconsultation for pediatric patients accounts for 14.36 percent of accepted articles. Surgery and general medicine were the most prevalent medical fields in the adults and pediatrics, respectively. Most teleconsultations were inland experiences (no=135), and the USA, Italy and Australia were the three top countries in this group. Non-specialists health care providers/centers were the dominant group who requested teleconsultation (no=130). Real time, store and forward, and hybrid technologies were used in 50, 31, and 16.7 percent of articles, respectively. The teleconsultation were reported to result in change in treatment plan, referral or evacuation rate, change in diagnosis, educational effects, and rapid decision making. Use of structured or semi-structured template had been noticed only in a very few articles. CONCLUSION: The present study focused on the recent ten years of published articles on physician-physician teleconsultations. Our findings showed that although there are positive impacts of teleconsultation as improving patient management, still have gaps that need to be repaired. PMID- 27708499 TI - Hyperspectral volumetric coherent anti-Stokes Raman scattering microscopy: quantitative volume determination and NaCl as non-resonant standard. AB - In this work, we demonstrate quantitative volume determination of chemical components in three dimensions using hyperspectral coherent anti-Stokes Raman scattering microscopy, phase-corrected Kramers-Kronig retrieval of the coherent anti-Stokes Raman scattering susceptibility and factorization into concentration of chemical components. We investigate the influence of the refractive index contrast between water and polymer beads (polystyrene and polymethylmethacrylate), showing that it leads mainly to concentration errors, while the spectral error is less affected. The volume of polystyrene beads of sizes from 200 nm to 3 MUm is determined with 10% relative error and 1% absolute error in the region of interest. We furthermore establish the use of sodium chloride as non-resonant reference material free of Raman-active vibrational resonances. PMID- 27708500 TI - Rate Constants and Activation Energies for Gas-Phase Reactions of Three Cyclic Volatile Methyl Siloxanes with the Hydroxyl Radical. AB - Reaction with hydroxyl radicals (OH) is the major pathway for removal of cyclic volatile methyl siloxanes (cVMS) from air. We present new measurements of second order rate constants for reactions of the cVMS octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6) with OH determined at temperatures between 313 and 353 K. Our measurements were made using the method of relative rates with cyclohexane as a reference substance and were conducted in a 140-mL gas-phase reaction chamber with online mass spectrometry analysis. When extrapolated to 298 K, our measured reaction rate constants of D4 and D5 with the OH radical are 1.9 * 10-12 (95% confidence interval (CI): (1.7-2.2) * 10-12) and 2.6 * 10-12 (CI: (2.3-2.9) * 10-12) cm3 molecule-1 s-1, respectively, which are 1.9* and 1.7* faster than previous measurements. Our measured rate constant for D6 is 2.8 * 10-12 (CI: (2.5-3.2) * 10-12) cm3 molecule-1 s-1 and to our knowledge there are no comparable laboratory measurements in the literature. Reaction rates for D5 were 33% higher than for D4 (CI: 30-37%), whereas the rates for D6 were only 8% higher than for D5 (CI: 5 10%). The activation energies of the reactions of D4, D5, and D6 with OH were not statistically different and had a value of 4300 +/- 2800 J/mol. PMID- 27708501 TI - The Social Costs of Gender Nonconformity for Transgender Adults: Implications for Discrimination and Health. AB - Research suggests that transgender people face high levels of discrimination in society, which may contribute to their disproportionate risk for poor health. However, little is known about whether gender nonconformity, as a visible marker of one's stigmatized status as a transgender individual, heightens trans people's experiences with discrimination and, in turn, their health. Using data from the largest survey of transgender adults in the United States, the National Transgender Discrimination Survey (N = 4,115), we examine the associations among gender nonconformity, transphobic discrimination, and health-harming behaviors (i.e., attempted suicide, drug/alcohol abuse, and smoking). The results suggest that gender nonconforming trans people face more discrimination and, in turn, are more likely to engage in health-harming behaviors than trans people who are gender conforming. Our findings highlight the important role of gender nonconformity in the social experiences and well-being of transgender people. PMID- 27708502 TI - Methodological considerations in the use of audio diaries in work psychology: Adding to the qualitative toolkit. AB - : The use of longitudinal methodology as a means of capturing the intricacies in complex organizational phenomena is well documented, and many different research strategies for longitudinal designs have been put forward from both a qualitative and quantitative stance. This study explores a specific emergent qualitative methodology, audio diaries, and assesses their utility for work psychology research drawing on the findings from a four-stage study addressing transient working patterns and stress in UK temporary workers. Specifically, we explore some important methodological, analytical and technical issues for practitioners and researchers who seek to use these methods and explain how this type of methodology has much to offer when studying stress and affective experiences at work. We provide support for the need to implement pluralistic and complementary methodological approaches in unearthing the depth in sense-making and assert their capacity to further illuminate the process orientation of stress. PRACTITIONER POINTS: This study illustrates the importance of verbalization in documenting stress and affective experience as a mechanism for accessing cognitive processes in making sense of such experience.This study compares audio diaries with more traditional qualitative methods to assess applicability to different research contexts.This study provides practical guidance and a methodological framework for the design of audio diary research and design, taking into account challenges and solutions for researchers and practitioners. PMID- 27708504 TI - Carboniferous Onychophora from Montceau-les-Mines, France, and onychophoran terrestrialization. AB - The geological age of the onychophoran crown-group, and when the group came onto land, have been sources of debate. Although stem-group Onychophora have been identified from as early as the Cambrian, the sparse record of terrestrial taxa from before the Cretaceous is subject to contradictory interpretations. A Late Carboniferous species from the Mazon Creek biota of the USA, Helenodora inopinata, originally interpreted as a crown-group onychophoran, has recently been allied to early Cambrian stem-group taxa. Here we describe a fossil species from the Late Carboniferous Montceau-les-Mines Lagerstatte, France, informally referred to as an onychophoran for more than 30 years. The onychophoran affinities of Antennipatus montceauensis gen. nov., sp. nov. are indicated by the form of the trunk plicae and the shape and spacing of their papillae, details of antennal annuli, and the presence of putative slime papillae. The poor preservation of several key systematic characters for extant Onychophora, however, prohibits the precise placement of the Carboniferous fossil in the stem or crown of the two extant families, or the onychophoran stem-group as a whole. Nevertheless, A. montceauensis is the most compelling candidate to date for a terrestrial Paleozoic onychophoran. PMID- 27708503 TI - Tuning supramolecular G-quadruplexes with mono- and divalent cations. AB - Supramolecular G-quadruplexes (SGQs) are formed via the cation promoted self assembly of guanine derivatives into stacks of planar hydrogen-bonded tetramers. Here, we present results on the formation of SGQs made from the 8-(m acetylphenyl)-2'-deoxyguanosine (mAGi) derivative in the presence of various mono and divalent cations. NMR and HR ESI-MS data indicate that varying the cation can efficiently tune the molecularity, the fidelity and stability (thermal and kinetic) of the resulting SGQs. The results show that, parallel to the previously reported potassium-templated hexadecamer (mAGi16.3K+), Na+, Rb+ and [Formula: see text] also promote the formation of similar supramolecules with high fidelity and molecularity. In contrast, the divalent cations Pb2+, Sr2+ and Ba2+ template the formation of octamers (mAGi8), with the latter two inducing higher thermal stabilities. Molecular dynamics simulations for the hexadecamers containing monovalent cations enabled critical insights that help explain the experimental observations. PMID- 27708506 TI - Barrett's esophagus: lessons from recent clinical trials. AB - Data from recent studies cast doubt on former recommendations on diagnosis and management of Barrett's esophagus. Based on latest research findings several Gastroenterological Associations actualized their guidelines and international experts compiled consensus statements as practical help for clinicians. In this review we discuss recent trials and their impact on clinical practice, current recommendations and persisting controversies in Barrett's esophagus. PMID- 27708508 TI - Fast-track drug approval in inflammatory bowel diseases. AB - Fast-track drug designation of safe regimens represents an emerging method of development and approval of new medications targeting debilitating diseases including inflammatory bowel diseases (IBD). The goal of accelerated drug approval pathways is to shorten the time between application and approval of therapies that treat diseases with significant morbidity and mortality. Recently, fast-track drug approval approaches were supported by data deriving from central reading of images, a method of clinical data interpretation that has significantly benefited patients with gastrointestinal disorders. Biological agents and other emerging therapies in IBD represent "game-changing" or "treat-to target" drugs and have satisfied quite successfully some of the patients' unmet needs. The development of biosimilars is an area where the Federal Drug Administration and the European Agency for Evaluation of Medicinal Products seem to have different approval processes. Biosimilars, including those for IBD, promise cost reductions and wide access to biologic therapies by patients, advantages similar to those already offered by generic drugs. Given the rapid development of IBD drugs and patients' needs, a consensus among the academic community, clinicians, researchers, sponsors, patients and regulatory authorities is required to standardize better the IBD trials and create a productive environment for fast-track approval of any "changing-game" IBD drug. PMID- 27708507 TI - Adipokines and the role of visceral adipose tissue in inflammatory bowel disease. AB - Recently, adipocytes have been recognized as actively participating in local and systemic immune responses via the secretion of peptides detectable in relevant levels in the systemic circulation, the so-called "adipo(cyto)kines". Multiple studies appearing within the last 10-15 years have focused on the possible impact of adipose tissue depots on inflammatory bowel disease (IBD). Consequently, various hypotheses regarding the role of different adipokines in inflammatory diseases in general and in intestinal inflammatory processes in particular have been developed and have been further refined in recent years. After a focused summary of the data reported concerning the impact of visceral adipose tissue on IBD, such as Crohn's disease and ulcerative colitis, our review focuses on recent developments indicating that adipocytes as part of the innate immune system actively participate in antimicrobial host defenses in the context of intestinal bacterial translocation, which are of utmost importance for the homeostasis of the whole organism. Modulators of adipose tissue function and regulators of adipokine secretion, as well as modifiers of adipocytic pattern recognition molecules, might represent future potential drug targets in IBD. PMID- 27708505 TI - Clinical practice guidelines for the management of metastatic colorectal cancer: a consensus statement of the Hellenic Society of Medical Oncologists (HeSMO). AB - There is discrepancy and failure to adhere to current international guidelines for the management of metastatic colorectal cancer (CRC) in hospitals in Greece and Cyprus. The aim of the present document is to provide a consensus on the multidisciplinary management of metastastic CRC, considering both special characteristics of our Healthcare System and international guidelines. Following discussion and online communication among the members of an executive team chosen by the Hellenic Society of Medical Oncology (HeSMO), a consensus for metastastic CRC disease was developed. Statements were subjected to the Delphi methodology on two voting rounds by invited multidisciplinary international experts on CRC. Statements reaching level of agreement by >=80% were considered as having achieved large consensus, whereas statements reaching 60-80% moderate consensus. One hundred and nine statements were developed. Ninety experts voted for those statements. The median rate of abstain per statement was 18.5% (range: 0-54%). In the end of the process, all statements achieved a large consensus. The importance of centralization, care by a multidisciplinary team, adherence to guidelines, and personalization is emphasized. R0 resection is the only intervention that may offer substantial improvement in the oncological outcomes. PMID- 27708509 TI - Evaluation of liver fibrosis: "Something old, something new...". AB - Hepatic fibrogenesis may gradually result to cirrhosis due to the accumulation of extracellular matrix components as a response to liver injury. Thus, therapeutic decisions in chronic liver disease, regardless of the cause, should first and foremost be guided by an accurate quantification of hepatic fibrosis. Detection and assessment of the extent of hepatic fibrosis represent a challenge in modern Hepatology. Although traditional histological staging systems remain the "best standard", they are not able to quantify liver fibrosis as a dynamic process and may not accurately substage cirrhosis. This review aims to compare the currently used non-invasive methods of measuring liver fibrosis and provide an update in current tissue-based digital techniques developed for this purpose, that may prove of value in daily clinical practice. PMID- 27708510 TI - Fibrosing cholestatic hepatitis C in post-transplant adult recipients of liver transplantation. AB - Hepatitis C recurrence continues to present a major challenge in liver transplantation (LT). Approximately 10% of hepatitis C virus (HCV)-positive recipients will develop fibrosing cholestatic hepatitis (FCH) after LT. FCH is clinically characterized as marked jaundice with cholestatic hepatic dysfunction and high titers of viremia. Pathologically, FCH manifests as marked hepatocyte swelling, cholestasis, periportal peritrabecular fibrosis and only mild inflammation. This progressive form usually involves acute liver failure, and rapidly results in graft loss. A real-time and precise diagnosis based on histopathological examination and viral measurement is indispensable for the adequate treatment of FCH. Typical pathological findings of FCH are shown. Currently, carefully selected combinations of direct-acting antivirals (DAAs) offer the potential for highly effective and safe regimens for hepatitis C, both in the pre- and post-transplant settings. Here, we review FCH caused by HCV in LT recipients, and current strategies for sustained virological responses after LT. Only a few cases of successfully treated FCH C after LT by DAAs have been reported. The diagnostic findings and therapeutic dilemma are discussed based on a literature review. PMID- 27708511 TI - Current role of microwave ablation in the treatment of small hepatocellular carcinomas. AB - Percutaneous radiofrequency ablation (RFA) can be as effective as surgical resection in terms of overall survival and recurrence-free survival rates in patients with small hepatocellular carcinoma (HCC). Effectiveness of RFA is adversely influenced by heat-sink effect. Other ablative therapies could be considered for larger tumors or for tumors located near the vessels. In this regard, recent improvements in microwave energy delivery systems seem to open interesting perspectives to percutaneous ablation, which could become the ablation technique of choice in the near future. Microwave ablation (MWA) has the advantages of possessing a higher thermal efficiency. It has high efficacy in coagulating blood vessels and is a relatively fast procedure. The time required for ablation is short and the shape of necrosis is elliptical with the older systems and spherical with the new one. There is no heat-sink effect and it can be used to ablate tumors adjacent to major vessels. These factors yield a large ablation volume, and result in good local control and fewer complications. This review highlights the most relevant updates on MWA in the treatment of small (<3 cm) HCC. Furthermore, we discuss the possibility of MWA as the first ablative choice, at least in selected cases. PMID- 27708513 TI - Percutaneous endoscopic colostomy: a useful technique when surgery is not an option. AB - Percutaneous endoscopic colostomy (PEC) is a minimally invasive endoscopic procedure that offers an alternative treatment for high-risk patients with sigmoid volvulus or intestinal pseudo-obstruction who have tried conventional treatment options without success or those who are unfit for surgery. The procedure acts as an irrigation or decompressing channel and provides colonic 'fixation' to the anterior abdominal wall. The risk of complications highlights the importance of informed consent for patients and relatives. PMID- 27708512 TI - Genetic factors affecting patient responses to pancreatic cancer treatment. AB - Cancer of the exocrine pancreas is a malignancy with a high lethal rate. Surgical resection is the only possible curative mode of treatment. Metastatic pancreatic cancer is incurable with modest results from the current treatment options. New genomic information could prove treatment efficacy. An independent review of PubMed and ScienceDirect databases was performed up to March 2016, using combinations of terms such pancreatic exocrine cancer, chemotherapy, genomic profile, pancreatic cancer pharmacogenomics, genomics, molecular pancreatic pathogenesis, and targeted therapy. Recent genetic studies have identified new markers and therapeutic targets. Our current knowledge of pancreatic cancer genetics must be further advanced to elucidate the molecular basis and pathogenesis of the disease, improve the accuracy of diagnosis, and guide tailor made therapies. PMID- 27708514 TI - Airway observations during upper endoscopy predicting obstructive sleep apnea. AB - BACKGROUND: This pilot study examined airway characteristics during upper endoscopy to determine who is at high risk for obstructive sleep apnea. METHODS: Patients undergoing routine upper endoscopy were divided into 2 groups according to the Berlin Questionnaire (high and low risk for sleep disordered breathing). Patients underwent routine upper endoscopy using propofol sedation. The airway was then evaluated for no, partial, or complete collapse at the levels of the palate/uvula/tonsils, the tongue base, the hypopharynx, and the larynx. They were given a score of 0 for no collapse, 1 for partial collapse, and 2 for complete collapse. The score for each of these levels was added to give a total score or severity index. The larynx was also evaluated for lateral pharyngeal collapse (minimal, up to 50%, >50%, or 100%). RESULTS: We found that patients with a partial obstruction at the level of the palate/uvula/tonsils, tongue base, hypopharynx, or larynx, or complete obstruction at any level more often had a positive Berlin questionnaire. Patients with a positive Berlin questionnaire were more often of increased weight (mean 197 vs 175 lbs, P=0.19), increased body mass index (31.2 vs 27.42 kg/m2, P=0.11), increased neck circumference (36.7 vs 34.7 cm, P=0.23), and had a higher total airway score (2.61 vs 1.67, P=0.09). CONCLUSIONS: The results of our pilot study represent preliminary data regarding the use of upper endoscopy as a potential tool to evaluate patients for obstructive sleep apnea. PMID- 27708515 TI - Irritable bowel syndrome might be associated with dry eye disease. AB - BACKGROUND: A possible association between dry eye disease (DED) and irritable bowel syndrome (IBS) has been hypothesized based on the fact that they both share an inflammatory pathogenesis. METHODS: Ninety-five patients with IBS and 276 healthy controls were enrolled in the study. All patients answered a questionnaire regarding DED symptoms and had a complete ophthalmic examination. DED signs were evaluated using Schirmer's 1 and tear break-up time (tBUT) tests in both groups. RESULTS: Female IBS participants presented significantly lower Schirmer's test and tBUT (P=0.002 and P<0.001 respectively) than controls. Both diagnostic tests in male IBS patients were also significantly lower than in controls (P<0.001). 72% of IBS patients gave at least 3 positive answers to the questionnaire compared with 42% of the control group (P<0.01). CONCLUSION: Our results suggest a correlation between IBS and DED. DED symptoms can cause further complications in patients with IBS, and should be considered in their management. However, further research is needed to establish a possible pathophysiologic association. PMID- 27708516 TI - Inflammatory bowel disease nurse specialists for patients on biological therapies: a nationwide Italian survey. AB - BACKGROUND: Management of inflammatory bowel disease (IBD) patients requires a multidisciplinary approach. Among the working team, the role of IBD nurse is expected to be particularly relevant when managing patients receiving biological therapies. We performed a survey to assess the presence of IBD nurse in centers where patients were receiving biologics. METHODS: For this Italian nationwide survey a specific questionnaire was prepared. IBD nurse was defined as a nurse directly involved in all phases of biological therapy, from pre-therapy screening, administration and monitoring during therapy, to follow up performed by a dedicated helpline, completed a specific training on biological therapy therapy, and observed international guidelines. RESULTS: A total of 53 Italian IBD centers participated in the survey, and 91 valid questionnaires were collected. Overall, 34 (37.4%) nurses could be classified as IBD specialists. IBD nurses had a significantly higher educational level than other nurses, they were more frequently operating in Central or Southern than in Northern Italy, they were working in an Academic center rather than in a General hospital, and in IBD centers with >25 patients on biological therapy. On the contrary, mean age, gender distribution, years of nursing, and years working in the IBD unit did not significantly differ between IBD and other nurses. CONCLUSIONS: Our nationwide survey showed that the presence of an IBD nurse is still lacking in the majority of Italian IBD centers where patients receive biological therapies, suggesting a prompt implementation. PMID- 27708517 TI - Differences between morning and afternoon colonoscopies for adenoma detection in female and male patients. AB - BACKGROUND: Colonoscopies performed in the afternoon (PM) have been shown to have lower adenoma detection rates (ADR) compared to those in the morning (AM). Endoscopist fatigue has been suggested as a possible reason. Colonoscopies tend to be technically more challenging in female patients. Furthermore, women have a lower incidence of adenomas then men. The impact of the timing of colonoscopy based on sex has not been studied. We hypothesized that any decrease in ADR in PM colonoscopies would be more pronounced in female patients when compared to male patients. METHODS: We retrospectively reviewed colonoscopies performed for screening or surveillance in our outpatient endoscopy center from January 2008 to December 2011. Complete colonoscopies with a documented cecal intubation were included. All patients with a history of colorectal cancer or colonic resection, inadequate bowel preparation, or incomplete data were excluded. RESULTS: A total of 2305 patients (1207 female) were included. Overall, ADR was significantly higher in AM than in PM procedures. Multivariate analysis demonstrated that ADR for females was lower in PM than in AM colonoscopies (odds ratio [OR] 0.63, 95% confidence interval [CI] 0.44-0.91, P=0.015). There was a non-significant trend towards a lower ADR for males in PM (OR 0.84, 95% CI 0.62-1.15, P=0.28). Females had a prolonged intubation time and a longer procedure time. CONCLUSION: The difference in ADR between AM and PM procedures seems to apply mainly to female patients. No significant change in ADR was noted in male patients in the afternoon. PMID- 27708518 TI - Prophylactic clipping and post-polypectomy bleeding: a meta-analysis and systematic review. AB - BACKGROUND: Bleeding after polypectomy is a common issue associated with colonoscopy. To help prevent post-polypectomy bleeding, many endoscopists place clips at the site. However, this practice remains controversial. Therefore, we performed a meta-analysis of the efficacy of clip placement in the prevention of post-polypectomy bleeding. METHODS: Multiple databases, including Embase, Scopus, MEDLINE/PubMed, CINAHL, Cochrane databases, and recent abstracts from major American meetings were searched in April 2016. Using the DerSimonian and Laird (random effects) model with odds ratio (OR), a meta-analysis was performed of post-polypectomy bleeding with prophylactic clip versus no prophylactic clip. RESULTS: Five hundred and thirty potential articles and abstracts were discovered. Thirty-five articles were reviewed, with 12 studies satisfying the inclusion criteria. No statistically significant difference in prophylactic clipping versus no prophylactic clipping for post-polypectomy bleeding in all polyps was found when all studies (OR 1.49; 95% CI: 0.56-4.00; P=0.42), only peer reviewed studies where abstracts were excluded (OR 0.84; 95% CI: 0.42-1.69; P=0.63), and only randomized controlled trials (OR 1.24; 95% CI: 0.69-2.24; P=0.47) were analyzed. CONCLUSIONS: The use of prophylactic clipping for all polypectomies does not seem to prevent post-polypectomy bleeding and should not be a routine practice. However, for large polyps (>2 cm), prophylactic clipping may or may not be beneficial in preventing post-polypectomy bleeding. Further studies are required to fully evaluate this subgroup. PMID- 27708519 TI - Handgrip dynamometry: a surrogate marker of malnutrition to predict the prognosis in alcoholic liver disease. AB - BACKGROUND: The aim of the study was to determine the utility of handgrip dynamometry (HGD) in predicting short term mortality and complications in alcoholic liver disease. METHODS: Patients with alcoholic liver disease were included and nutritional assessment was done using the Subjective Global Assessment (SGA), HGD and other conventional parameters. Mortality rates and complications were compared to nutritional status. RESULTS: 80 patients were included in the study. Mean age of patients was 43.06+/-10.03 years. 69 patients survived and 11 patients died within the 3 month study duration. Handgrip strength (HGS) was higher in SGA A (28.76+/-5.48 kg) than SGA B (22.43+/-4.95 kg) and SGA C (16.78+/-3.83 kg) (P=<0.001). Number of complications including spontaneous bacterial Peritonitis, gastrointestinal bleeding and encephalopathy in SGA C group were 66.66%, in SGA B 20.75% and SGA A 10%. Mean HGS was significantly higher in the survivors (24.23+/-5.86) compared to non-survivors (18.04+/-4.82) (P=0.0011). There was a strong negative correlation between the HGS and Child-Pugh score (P=<0.0012). Multivariate logistic regression analysis to assess the risk factors for death showed handgrip to be in the suggestive significance range (P=0.072). The sensitivity of HGS was 88.41% in predicting short term mortality. CONCLUSIONS: HGS correlates with Child-Pugh score in predicting short term mortality. HGD is a simple, inexpensive and sensitive tool for assessing the nutritional status in alcoholic liver disease and can reliably predict its complications and survival. PMID- 27708520 TI - Predictors of hospital re-admissions among Hispanics with hepatitis C-related cirrhosis. AB - BACKGROUND: Hospital re-admissions in decompensated cirrhosis are associated with worse patient outcomes. Hispanics have a disproportionately high prevalence of hepatitis C virus (HCV)-related morbidity and mortality. The goal of this study was to evaluate the factors affecting re-admission rates among Hispanics with HCV related cirrhosis. METHODS: A total of 292 consecutive HCV-related cirrhosis admissions (Hispanics 189, non-Hispanics 103) from January 2009 to December 2012 were retrospectively reviewed; 132 were cirrhosis-related re-admissions. The statistical analysis was performed using STATA version 11.1. Chi-square/Fisher's exact and Student's t-tests were used to compare categorical and continuous variables, respectively. Multivariate logistic regression analysis was performed to identify predictors for hospital readmissions. RESULTS: Among the 132 cirrhosis-related readmissions, 71% were Hispanics while 29% were non-Hispanics (P=0.035). Hepatic encephalopathy (HE) and esophageal variceal hemorrhage were the most frequent causes of the first and subsequent readmissions. Hispanics with readmissions had a higher Child-Turcotte-Pugh (CTP) class (B and C) and higher model for end-stage liver disease (MELD) scores (>=15), as well as a higher incidence of alcohol use, HE, spontaneous bacterial peritonitis, hepatocellular carcinoma, and varices (P<0.05). The majority of the study patients (81%) had MELD scores <15. Multivariate regression analysis identified alcohol use (OR 2.63; 95%CI 1.1-6.4), HE (OR 5.5; 95%CI 2-15.3), varices (OR 3.2; 95%CI 1.3-8.2), and CTP class (OR 3.3; 95%CI 1.4-8.1) as predictors for readmissions among Hispanics. CONCLUSION: CTP classes B and C, among other factors, were the major predictors for hospital readmissions in Hispanics with HCV-related cirrhosis. The majority of these readmissions were due to HE and variceal hemorrhage. PMID- 27708521 TI - Laparoscopic versus open liver resection for hepatocellular carcinoma: initial experience in Greece. AB - BACKGROUND: Liver resection represents the treatment of choice for a small proportion of patients with hepatocellular carcinoma (HCC), amenable to surgery. The remarkable evolution in surgical techniques during the last decades introduced laparoscopic hepatectomy in the operative management of HCC, even in the presence of liver cirrhosis. No comparative study on laparoscopic or open liver resection for HCC has been conducted in Greece yet. METHODS: Patients undergoing liver resection for HCC by one senior hepatobiliary surgeon in our Institution during the period 11/2011-02/2016 were prospectively sampled and retrospectively analyzed for the purposes of this study. Statistical analysis encompassed Student's t-test, Fisher's exact test, the Kaplan-Meier method/log rank test and Cox proportional hazard regression analyses. RESULTS: Eleven patients underwent laparoscopic and 21 open liver resection, respectively. Statistical differences between the 2 groups were observed for tumor size (P=0.04), major resections (P=0.01), Pringle maneuver (P=0.008), intraoperative blood transfusion (P=0.03), and duration of operation (P=0.004). Resection margins, and tumor recurrence showed no statistical differences. Three-year postoperative survival after laparoscopic and open hepatectomy was 100%, and 67%, respectively (P=0.06). Regression analysis for patient survival revealed prognostic value for BCLC staging, gamma-glutamyl transferase levels, laparoscopic hepatectomy, UICC stage, Dindo-Clavien classification, and hospital stay. Laparoscopic hepatectomy remained as independent predictor of survival by multivariate analysis (P=0.0142). CONCLUSION: Laparoscopic hepatectomy for HCC in chronic liver disease represents a safe and innovative treatment tool in the management of these patients under the presupposition of careful patient selection. PMID- 27708524 TI - Esophagogastric fistula: a rare complication of laparoscopic Nissen fundoplication. PMID- 27708522 TI - Anesthesia for endoscopic retrograde cholangiopancreatography: target-controlled infusion versus standard volatile anesthesia. AB - BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a technique used both for diagnosis and for the treatment of biliary and pancreatic diseases. ERCP has some anesthetic implications and specific complications. The primary outcome aim was to compare two protocols in terms of time of extubation. We also compared anesthetic protocols in terms of hemodynamic and respiratory instability, antispasmodics needs, endoscopist satisfaction, and recovery room stay. METHODS: Patients were randomized into two groups standard anesthesia group (Gr: SA) in whom induction was done by propofol, fentanyl and cisatracurium and maintenance was done by a mixture of oxygen, nitrousoxide (50%:50%) and sevoflurane; and intravenous anesthesia group to target concentration (Gr: TCI) in whom induction and maintenance of anesthesia were done with propofol with a target 0.5-2 MUg/mL, and remifentanil with a target of 0.75-2 ng/mL. RESULTS: 90 patients were included. Extubation time was shorter in Gr: TCI, 15+/-2.6 vs. 27.4+/-7.1 min in Gr: SA (P<0.001). The incidence of hypotension was higher in GrL: SA (P=0.009). Satisfaction was better in Gr: TCI (P=0.003). Antispasmodic need was higher in Gr: SA (P=0.023). Six patients in Gr: SA group had desaturation in post-anesthesia care unit (PACU) versus one patient from Gr: TCI (P=0.049). Patients in Gr: TCI had shorter PACU stay 40.2+/-7.3 vs. 58.7+/-12.4 min (P<0.001). CONCLUSION: The use of TCI mode allows better optimization of general anesthesia technique during ERCP. PMID- 27708523 TI - Role of methylphenidate in the treatment of fatigue in advanced pancreatic cancer population. AB - BACKGROUND: Fatigue is a common but devastating symptom for advanced pancreatic cancer (APC) patients. To date, no proven treatment exists. Methylphenidate (MPH) showed inconsistent results in treating other cancer related fatigue. We performed a retrospective study to assess MPH in ameliorating fatigue in APC patients. METHODS: We retrospectively reviewed our clinic APC patients' records who visited from 06/2011 - 11/2014. Fatigue was assessed by Visual Analog Fatigue Scale (VAFS) and classified as grade 1 (VAFS 1-3), grade 2 (VAFS 4-6) and grade 3 (VAFS 7-10) to correspond with CTCAE V4.0. MPH was dosed at 5 mg daily in the morning and was escalated to 10 mg after 2 weeks if needed. The primary endpoint was to assess the change of fatigue grade after 4 weeks of MPH. Secondary outcomes included MPH's effect on depression, anorexia, maintenance chemotherapy intensity and adverse effects. RESULTS: A total of 71 APC patients on concomitant chemotherapy were included, of whom 67% received doublet, 13% triplet, and 20% single-agent chemotherapy. Mean baseline VAFS was 7, which dropped to 4 after 4 weeks of MPH, 55% patients' fatigue score improved by 1 grade, 8% by 2 grades, 23% had fatigue resolved, 14% without benefit. 72% patients maintained chemotherapy intensity, 39% felt less depression and 52% had improved appetite. 13% stopped MPH due to side effects. Rare Grade 3 or 4 adverse events included insomnia, restlessness, palpitations and anorexia. CONCLUSIONS: Our findings support low-dose MPH benefits APC patients with improved fatigue, depression and anorexia. A large randomized clinical trial is needed to confirm its usage and safety.

AB - Gastroesophageal reflux disease (GERD) is recognized to be a multifactorial disease and several mechanisms leading to reflux have been described, nevertheless its pathophysiology has not been fully clarified. Hiatus hernia is a known risk factor for GERD since it impairs the esophagogastric junction, leading to: reduction in lower esophageal sphincter pressure; increase in the frequency of the transient lower esophageal sphincter relaxation; and impairment of esophageal clearance. Last generation diagnostic techniques have improved the understanding of these mechanisms. A 72-year-old woman with hiatus hernia and GERD underwent a high resolution impedance manometry (HRIM) after a partial response to treatment with pantoprazole. None of the proposed pathophysiological mechanisms for GERD could explain the presence of reflux: HRIM showed normal lower esophageal sphincter (LES) pressure and contractile integral, complete bolus clearance in all test swallows, and absence of transient LES relaxation. However, after the end of each peristaltic wave, as the LES pressure returned to resting values, a gastroesophageal reflux was detected until the following swallow. We describe an interesting case of a patient with a sliding hiatus hernia, with symptoms suggestive of GERD, in which HRIM revealed a new possible mechanism through which hiatus hernia may lead to GERD. PMID- 27708529 TI - Imatinib-induced hyperbilirubinemia with UGT1A1 (*28) promoter polymorphism: first case series in patients with gastrointestinal stromal tumor. AB - Imatinib, an orally administered protein-tyrosine kinase inhibitor (TKI) is indicated for the treatment of chronic myeloid leukemia (CML) and gastrointestinal stromal tumor (GIST). Severe hepatotoxicity associated with imatinib is rare, and relationship to polymorphism of uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) expression and related frequency of hyperbilirubinemia or toxicity are not well known. We present a case series patients who developed hyperbilirubinemia while on oral administration imatinib for treatment of GIST. Genetic testing for polymorphism of UGT1A1 showed the first patient to be homozygous for the UGT1A1 TA7 (*28) polymorphism and the second patient heterozygous for the UGT1A1 TA1 (*28) polymorphism. The first patient had to stop imatinib due to severe and persistent hyperbilirubenemia peaking >3 despite reducing imatininb to only 100 mg every other day while the second patient improved at this dose. Our case series represent the first data associating UGT1A1 polymorphism and imatinib in patients being treated for GIST. Given the prevalence of Gilbert's syndrome and the increasing use of imatinib, we encourage physicians to be aware of this possible toxicity as hepatotoxicity can be fatal if not managed in a timely fashion. This association is also timely due to recent FDA requirement for testing UGT1A1 polymorphism for nilotinib, another TKI. PMID- 27708530 TI - Esophageal location of mantle cell lymphoma.

PMID- 27708533 TI - Rice Bran Dietary Supplementation Improves Neurological Symptoms and Loss of Purkinje Cells in Vitamin E-Deficient Mice. AB - BACKGROUND: Vitamin E (VE, alpha-tocopherol) is a fat-soluble vitamin and is well known as an antioxidant. A deficiency in VE induces oxidative stress in the brain and causes motor and memory dysfunction. The consumption of a VE-rich diet has been given much attention in recent years, in regards to anti-aging and the prevention of age-related neuronal disorders. METHODS: A VE-deficient mouse model was prepared by feeding the animals a diet lacking VE. In addition, to evaluate the effect of VE-containing rice bran (RB) on VE deficiency, a diet including RB was also provided. VE levels in the brain tissue, as well as in the RB, were measured using an HPLC system. Behavioral tests, including rotarod, wheel running activity, Y-maze, and elevated plus maze were performed. To clarify the effect of VE deficiency and RB, we investigated the induction of heme oxygenase-1 (HO-1). Histological studies were performed using HE staining and immunohistochemical studies were performed using antibodies against glial fibrillary acidic protein (GFAP) and ionized calcium binding adaptor molecule 1 (Iba1). RESULTS: VE in the mouse brain under a VE-deficient diet was decreased, and recovered alpha tocopherol levels were observed in the brain of mice fed an RB diet. Motor behavioral scores were decreased in VE-deficient conditions, while the supplementation of RB improved motor function. HO-1, a marker of oxidative stress, was upregulated in the mouse brain under VE deficiency, however, RB supplementation inhibited the increase of HO-1. Histological analyses showed neuronal degeneration of Purkinje cells and decreased GFAP-immunoreactivity of Bergmann glia in the cerebellum. In addition, activated astrocytes and microglia were observed in mice fed the VE-deficient diet. Mice fed the RB diet showed improvement in these histological abnormalities. CONCLUSION: A VE-deficient diet induced motor dysfunction in mice due to the degeneration of Purkinje cells in the cerebellum. Oral supplementation of RB increases VE in the brain and improved the motor dysfunction caused by VE deficiency. Thus, RB or unpolished rice may be a promising VE supplement. PMID- 27708534 TI - Qualitative Analysis of the Resilience of Adult Japanese Patients with Type 1 Diabetes. AB - BACKGROUND: Resilience strategies are what we use to avoid and recover from error. In this study, we used the grounded theory approach to evaluate the resilience of Japanese patients with Type 1 diabetes. METHODS: Semi-structured interviews were conducted with 15 adults with Type 1 diabetes. Then, using grounded theory, we created a new model of resilience in this population. RESULTS: The results suggested a core category, "to make progress along the resilience path," comprising seven concepts classified into three stages. These seven concepts were as follows: "suffering from treatment," "damaged trust as a person," "persistence of afflictions," "awareness of supporters," "joy to be kept alive by insulin," "actively seeking a future," "being able to manage by oneself." Individuals with Type 1 diabetes used difficult experiences to motivate their resilience and to improve their situation. Additionally, resilience was an important contributor to these individuals' beliefs in their ability to face difficulties, to accept their illness and insulin therapy, and to control their illness. Resilience was also important to these individuals' faith in the future and in medical care. Our results are applicable to clinical care and research, such as the development of preventive interventions aimed at building or strengthening protective skills related to diabetes and its management. CONCLUSION: Ultimately, our goal is to equip adults with Type 1 diabetes with the tools to obtain sufficient behavioral and health-related resilience. Furthermore, these results highlight that maintaining resilience-related coping skills is important for adults and indicate that different psychological processes underlie resilience across the lifespan. PMID- 27708535 TI - R2* Map by IDEAL IQ for Acute Cerebral Infarction: Compared with Susceptibility Vessel Sign on T2*-Weighted Imaging. AB - BACKGROUND: To evaluate the detectability of arterial acute thrombus on R2* map by iterative decomposition of water and fat with echo asymmetry and least-squares estimation (IDEAL) IQ compared with T2*-weighted imaging (T2*WI). METHODS: Twenty six patients with acute cerebral infarction who underwent R2* map and T2*WI were reviewed. We performed visual assessment of each sequence regarding the visibility of susceptibility effect reflecting acute thrombus and quantitative evaluation of the thrombus on R2* map. RESULTS: Both R2* map and T2*WI showed susceptibility effect reflecting acute thrombi at the occluded site of magnetic resonance angiography (MRA) in 9 patients. R2* map revealed positive while T2*WI showed equivocal findings in 3 patients due to the surrounding vessel signal intensity. Acute thrombus at distal internal carotid artery (ICA) on R2* map was more clearly detected than that on T2*WI without any apparent susceptibility artifact from the skull base in 4 patients. Most of cardiogenic embolic infarction (CEI) and artery-to-artery embolic infarction (A-to-A) demonstrated positive and most of atherothrombotic infarction (ATI) revealed negative findings on R2* map, although quantitative R2* values of thrombi did not show significant differences between CEI (136.6 /msec) and A-to-A (189.9 /msec) (P = 0.332). CONCLUSION: The detectability of acute thrombus on R2* map is comparable to that on T2*WI. Regarding thrombus at distal ICA, its detectability on R2* map is superior to that on T2*WI. R2* map provide additional information to distinguish between embolic and atherothrombotic infarctions.

AB - A series of beta,beta'-bicyclo-3,5-diaryl-BODIPYs were synthesized from the corresponding beta,beta'-bicyclo-3,5-diiodo-BODIPYs (1a,b) via Pd(0)-mediated Suzuki cross-coupling reactions in 82-92% yields. Subsequent aromatization with DDQ afforded the corresponding beta,beta'-dibenzo-aryl-BODIPYs, which showed red shifted absorptions and emissions in the near-IR range. The dibenzo-appended BODIPYs showed characteristic 1H-, 13C-, 11B- and 19F-NMR shifts, and nearly planar conformations by X-ray crystallography. PMID- 27708537 TI - Construction and Evaluation of Cytomegalovirus DNA Quantification System with Real-Time Detection Polymerase Chain Reaction. AB - BACKGROUND: For patients with reactivation of human cytomegalovirus (CMV), a highly sensitive and accurate CMV quantification system is essential to monitor viral load. METHODS: We constructed a real-time detection PCR (RTD-PCR) system for CMV DNA and evaluated its linearity, lower detection limit, dynamic range and accuracy using two CMV standards. We used 219 clinical samples derived from 101 patients to compare the system with the pp65 antigen test. RESULTS: The 95% detection limit was determined to be 556 IU/mL (95% CI, 440-797 IU/mL), and the quantification range was between 102 and 106 copies or IU/mL (r = 0.996, 0.999, respectively). The coefficients of variation of inter-assay reproducibility assessed in each three different runs were 2.5% at 1,000 IU/mL and 1.6% at 10,000 IU/mL. The coefficients of variation of intra-assay variability by testing the same samples three times in a single run were 1.8-3.6% and 0.4-1.9%, respectively. The concordance between antigenemia and plasma or serum CMV DNA levels was a good correlation (r = 0.695, P < 0.01). CONCLUSION: We constructed the RTD-PCR system which enables accurate evaluation of CMV reactivation by monitoring of viral load in immunosuppressed or immunocompromised patients. PMID- 27708536 TI - Intra-Abdominal Complications after Curative Gastrectomies Worsen Prognoses of Patients with Stage II-III Gastric Cancer. AB - BACKGROUND: Postoperative complications have been shown to worsen prognoses of various cancer types. METHODS: We retrospectively analyzed 265 patients with stage II-III gastric cancer who underwent curative gastrectomies between 1991 and 2010 at Tottori University Hospital to determine the effect of postoperative intra-abdominal complication (IAC) on prognosis. RESULTS: Of the 265 patients, 38 (14.3%) developed postoperative IACs of grade >= 2, of whom significantly more patients were male. Patients in the IAC group were significantly older than patients in the non-complication (NC) group. The NC group had significantly better survival than did the IAC group (P < 0.0001). Within the IAC group, 5-year survival rates did not significantly differ between patients with infectious complication subgroup (24.6%) and the non-infectious subgroup (46.2%). Grade of complication was not related to prognosis. Lengths of time before starting adjuvant chemotherapy (AC) after surgery were significantly longer for the IAC group (55.3 +/- 34.7 days) than for the NC group: (26.6 +/- 11.9 days; P = 0.0023). Prognosis of patients who took AC within 6 weeks after surgery tended to be better than that of patients who took AC > 6 weeks after surgery (P = 0.071). In multivariate analysis, IAC was an independent predictor of prognosis, as were age, invasion depth, and lymph node metastasis. CONCLUSION: Postoperative IACs were related to poorer survival for patients with stage II-III gastric cancer. PMID- 27708538 TI - Preconditioning by Low Dose LPS Prevents Subsequent LPS-Induced Severe Liver Injury via Nrf2 Activation in Mice. AB - BACKGROUND: Sepsis is a syndrome triggered by endotoxin lipopolysaccharide (LPS) during bacterial infection. Sepsis sometimes recurs, with the second sepsis giving rise to a different phenotype because of disease modification by the preceding sepsis. Such a protective modification is called a preconditioning (PC) effect. PC is an endogenous protective mechanism by which sublethal damage confers tolerance to a subsequent lethal load. Oxidative stress is one of the important pathogenetic mechanisms that occur in sepsis. The nuclear factor erythroid 2 (NF-E2)-related factor-2 (Nrf2) system is a key regulatory transcription factor that protects organs and cells against oxidative stress and may be associated with the PC effect in repeated sepsis. METHODS: The effect of PC induced by low-dose LPS on survival rate and liver injury against subsequent high-dose LPS stimulation was examined using a mouse model of sepsis. In order to understand the detailed mechanism(s) involved in the PC effect within the liver, gene expression array was performed. As a candidate mechanism of PC, the activation of the Nrf2 system was analyzed using Nrf2 reporter mice. Furthermore, the induction of heme oxygenase-1 (HO-1), one of the main targets of Nrf2, in the liver was examined by immunoblotting and immunohistochemistry. The PC effect on liver injury induced by LPS was further examined using Nrf2-deficient mice. RESULTS: PC by LPS (1.7 or 5.0 mg/kg body weight, intraperitoneally) increased the survival rate of mice and decreased liver injury in response to a subsequent injection of a lethal level of LPS (20 mg/kg body weight). DNA array revealed that the gene ontology term "antioxidant activity" as one of the candidate mechanisms of the PC effect by LPS. In Nrf2 reporter mice, PC immediately and intensely enhanced luminescence that indicated Nrf2 activation after subsequent LPS injection. The induction of HO-1 by LPS was also enhanced by preceding PC, and its induction was observed mainly in Kupffer cells of the liver. In Nrf2 deficient mice, the induction of HO-1 in Kupffer cells and the hepatoprotective effect of PC were decreased as compared with wild-type mice. CONCLUSION: Our results suggest that activation of the Nrf2 system is, at least in part, one of the mechanisms of a PC effect in the mouse liver in the case of repeated LPS stimulation. PMID- 27708539 TI - Usefulness of T-Shaped Gauze for Precise Dissection of Supra-Pancreatic Lymph Nodes and for Reduced Postoperative Pancreatic Fistula in Patients Undergoing Laparoscopic Gastrectomy for Gastric Cancer. AB - BACKGROUND: Supra-pancreatic lymph node dissection is important in patients undergoing laparoscopic gastrectomy (LG) for gastric cancer. A clear view of the supra-pancreatic area is necessary for precise dissection of supra-pancreatic lymph nodes without injury to the pancreas. This retrospective study assessed the efficacy of T-shaped gauze (TSG) in retracting the pancreas during supra pancreatic lymph node dissection. METHODS: The study cohort consisted of 80 patients who underwent LG for gastric cancer. Of these, 44 patients underwent pancreatic retraction with TSG (TSG group) and 36 without TSG (non-TSG group). The efficacy of TSG for pancreatic retraction was evaluated by comparing all grade and Clavien-Dindo grade >= III postoperative pancreatic fistula (POPF) and the total number of dissected supra-pancreatic lymph nodes in the TSG and non-TSG groups. RESULTS: The rates of all grade (6.8% vs. 11%) and of Clavien-Dindo grade >= III (2.2% vs. 5.5%) POPF were lower in the TSG than in the non-TSG group. The total number of supra-pancreatic lymph nodes harvested by Dissection 1+ (D1+) lymph node dissection was significantly higher in TSG than in non-TSG patients (P = 0.0078). CONCLUSION: TSG may be useful for safe and efficient performance of supra-pancreatic lymph node dissection. PMID- 27708540 TI - Combination Therapy of Interventional Radiology and Surgery for Infarction of the Small Intestine Caused by Portal Vein and Mesenteric Vein Thrombosis: A Patient Report. AB - We report the case of a man in his 70s who suffered from intestinal infarction caused by acute portal vein and mesenteric vein thrombosis (PVMVT). Combination therapy with percutaneous transcatheter thrombectomy and surgical bowel resection was successfully performed, and a satisfactory outcome was achieved. Intestinal infarction caused by PVMVT can be fatal and has a high mortality rate even if surgical resection is performed. The combination therapy of interventional radiology and surgery might be a safe and effective method for patients with this life-threatening condition. PMID- 27708541 TI - Analysis of Direct Simultaneous Measurement of Glottal Airflow Velocity, Subglottal Pressure, and High-Speed Imaging Using Flexible Transnasal Endoscope in a Human Subject. AB - It is difficult to directly observe glottal airflow velocity just above the glottis due to sensor size requirements and limited accessibility. We developed a miniature hot-wire probe and flexible fiberscopic high-speed imaging system for human examinations. Simultaneous direct measurement of glottal airflow velocity, subglottal pressure, and vocal fold vibration was achieved in a patient who was treated with a T-tube for tracheal stenosis. Airflow velocity changes at the anterior midline of the vocal folds were synchronized with subglottal pressure changes during each phonation cycle. The velocity at the anterior midline of the vocal folds showed a rhythmic pattern of sharp, high peaks. The result of fast Fourier transform analysis indicated that glottal velocity at the anterior midline of the vocal folds had abundant high-frequency components that were not affected by resonance of the vocal tract. Airflow velocity was variable and diminished except at the anterior midline of the vocal folds. PMID- 27708542 TI - Atypical Arteritis in Internal Carotid Arteries: A Novel Concept of Isolated Internal Carotid Arteritis. AB - We presented a 38-year-old woman suffering from acute cerebral infarction due to arteritis limited to bilateral internal carotid arteries without a condition of giant cell arteritis or granulomatosis with polyangitis. Our case is unprecedented and characterized by a young woman with wall enhancement in the internal carotid arteries on contrast-enhanced magnetic resonance imaging (MRI), therapeutic effects of steroids, and positive status for human leucocyte antigen B39, -B51 and -DR4. These disease characteristics were not in accordance with existing diagnostic criteria of vasculitis, such as Takayasu's arteritis, giant cell arteritis, granulomatosis with polyangiitis, and Behcet's disease. We suggested consideration of a novel "isolated internal carotid arteritis" disease concept. PMID- 27708544 TI - Justice-based social assistance. AB - What are the main objectives of social protection institutions in developing countries? What should be their scope and reach? What is the source of their legitimacy? Finding appropriate answers to these questions is essential to understanding, and shaping, the emergence of welfare institutions in low- and middle-income countries. Most available answers rely on instrumental arguments. Few make reference to normative principles. This article draws on three concepts from Rawls - social justice as regulating cooperation, the social minimum, and the need for a freestanding political notion of social justice - to develop a coherent argument for grounding social assistance on social justice. In line with this argument, it identifies some parameters for a justice-based social assistance. This article then discusses, with examples, the tensions existing between a social justice-based social minimum and 'real' social assistance institutions emerging in developing countries. PMID- 27708543 TI - Molecular basis of human cerebral malaria development. AB - Cerebral malaria is still a deleterious health problem in tropical countries. The wide spread of malarial drug resistance and the lack of an effective vaccine are obstacles for disease management and prevention. Parasite and human genetic factors play important roles in malaria susceptibility and disease severity. The malaria parasite exerted a potent selective signature on the human genome, which is apparent in the genetic polymorphism landscape of genes related to pathogenesis. Currently, much genomic data and a novel body of knowledge, including the identification of microRNAs, are being increasingly accumulated for the development of laboratory testing cassettes for cerebral malaria prevention. Therefore, understanding of the underlying complex molecular basis of cerebral malaria is important for the design of strategy for cerebral malaria treatment and control. PMID- 27708545 TI - Chromosomal abnormality of acute promyelocytic leukemia other than PML-RARA: a case report of acute promyelocytic leukemia with del(5q). AB - BACKGROUND: The recent study described a better outcome in acute promyelocytic leukemia patients treated with all-trans retinoic acid and arsenic oxide compared to those treated with all-trans retinoic acid combined with conventional chemotherapy. The pivotal study indicated that favorable-risk acute promyelocytic leukemia patients can be cured without any cytotoxic chemotherapy. Even high-risk patients are treatable with cytotoxic agents. Acute promyelocytic leukemia does not develop only by the dedifferentiation caused by PML-RARA. A determined oncogene other than PML-RARA which promotes cell proliferation would be required. CASE PRESENTATION: We recently treated a 30-year-old Japanese female who achieved molecular remission with only the administration of all-trans retinoic acid. The patient's leukemic clones concomitantly had a del(5q) aberrant chromosome with t(15;17) (q22;q12). The patient's bone marrow cells indicated clonal evolution of the tumor cells expressing CD13dim, CD33+, CD117+, and lacking HLA-DR, CD34 and CD11b. A fluorescence in situ hybridization analysis detected PML-RARA fusion genes in the patient's bone marrow specimens, leading to the diagnosis of acute promyelocytic leukemia. CONCLUSION: A del(5q) is one of the characteristic chromosomal abnormalities observed in myelodysplastic syndrome. On the other hand, up to 40 % of acute promyelocytic leukemia cases are known to harbor the addition of a clonal cytogenetic abnormality. However, such a case acute promyelocytic leukemia with del(5q) would be rare, rather than myelodysplastic syndrome, consequently obtaining t(15;17). Which cytogenetic abnormalities, acute promyelocytic leukemia or myelodysplastic syndrome, came first is informative to make a clinical decision for the initial therapy. In this case, we speculated the PML-RARA translocation is an original pathogenesis and thereafter additional cytogenetic abnormalities (del(5q) and -6) common in myelodysplastic syndrome. All-trans retinoic acid lead the patient into molecular remission. We propose that an assessment of additional cytogenetic abnormality in acute promyelocytic leukemia would contribute to the clinical decisions regarding whether to treat disease with all-trans retinoic acid and cytotoxic agents. It would be of interest to know the extent of cytogenetic abnormality in the patients regarding to mixed leukemia. One or more additional cytogenetic abnormalities other than PML-RARA could account for the biological malignant grade and prognostic index. PMID- 27708546 TI - The impact of occupational stress on nurses' caring behaviors and their health related quality of life. AB - BACKGROUND: Nursing is perceived as a strenuous job. Although past research has documented that stress influences nurses' health in association with quality of life, the relation between stress and caring behaviors remains relatively unexamined, especially in the Greek working environment, where it is the first time that this specific issue is being studied. The aim was to investigate and explore the correlation amidst occupational stress, caring behaviors and their quality of life in association to health. METHODS: A correlational study of nurses (N = 246) who worked at public and private units was conducted in 2013 in Greece. The variables were operationalized using three research instruments: (1) the Expanded Nursing Stress Scale (ENSS), (2) the Health Survey SF-12 and (3) the Caring Behaviors Inventory (CBI). Univariate and multivariate analyses were performed. RESULTS: Contact with death, patients and their families, conflicts with supervisors and uncertainty about the therapeutic effect caused significantly higher stress among participants. A significant negative correlation was observed amidst total stress and the four dimensions of CBI. Certain stress factors were significant and independent predictors of each CBI dimension. Conflicts with co-workers was revealed as an independent predicting factor for affirmation of human presence, professional knowledge and skills and patient respectfulness dimensions, conflicts with doctors for respect for patient, while conflicts with supervisors and uncertainty concerning treatment dimensions were an independent predictor for positive connectedness. Finally, discrimination stress factor was revealed as an independent predictor of quality of life related to physical health, while stress resulting from conflicts with supervisors was independently associated with mental health. CONCLUSION: Occupational stress affects nurses' health-related quality of life negatively, while it can also be considered as an influence on patient outcomes. PMID- 27708547 TI - Life is determined by its environment. AB - A well-developed theory of evolutionary biology requires understanding of the origins of life on Earth. However, the initial conditions (ontology) and causal (epistemology) bases on which physiology proceeded have more recently been called into question, given the teleologic nature of Darwinian evolutionary thinking. When evolutionary development is focused on cellular communication, a distinctly different perspective unfolds. The cellular communicative-molecular approach affords a logical progression for the evolutionary narrative based on the basic physiologic properties of the cell. Critical to this appraisal is recognition of the cell as a fundamental reiterative unit of reciprocating communication that receives information from and reacts to epiphenomena to solve problems. Following the course of vertebrate physiology from its unicellular origins instead of its overt phenotypic appearances and functional associations provides a robust, predictive picture for the means by which complex physiology evolved from unicellular organisms. With this foreknowledge of physiologic principles, we can determine the fundamentals of Physiology based on cellular first principles using a logical, predictable method. Thus, evolutionary creativity on our planet can be viewed as a paradoxical product of boundary conditions that permit homeostatic moments of varying length and amplitude that can productively absorb a variety of epigenetic impacts to meet environmental challenges. PMID- 27708548 TI - KIAA0101, a target gene of miR-429, enhances migration and chemoresistance of epithelial ovarian cancer cells. AB - BACKGROUND: Ovarian cancer is a common type of gynecological malignancies, and is the fifth leading cause of cancer-related death in women in the United States. MiR-429 and KIAA0101 have been found to be involved in several human malignancies, respectively. However, the role of miR-429 and KIAA0101, and the correlation between them during development of epithelial ovarian cancer (EOC) remain to be investigated. METHODS: The expression of KIAA0101 in EOC tissues and cells was measured by Quantitative real-time PCR, western blot, and immunochemistry. Cell proliferation assay, colony formation assay, and transwell assay was performed to assess the role of miR-429 and KIAA0101 in regulation of proliferation, migration, and chemoresistance of EOC cells. Luciferase assay was used to test the Wnt/beta-catenin signaling activity in response to depletion of KIAA0101 and overexpression of miR-429. RESULTS: We found that KIAA0101 was upregulated in metastatic EOC tissues, compared to primary EOC tissues, and KIAA0101 was required for the migration activity and chemoresistance of EOC cells by enhancing Wnt/beta-catenin signaling. Furthermore, we revealed KIAA0101 is direct target of miR-429. Similar to knockdown of KIAA0101, overexpression of miR 429 reduced invasion and chemoresistance of EOC cells. Co-transfection of KIAA0101 partially abrogates the inhibitory effects on invasion and chemoresistance in EOC cells. CONCLUSIONS: KIAA0101, a target gene of miR-429, was upregulated in the metastatic EOC tissues, and enhanced the migration activity and chemoresistance of EOC cells. Both miR-429 and KIAA0101 may represent the potential therapeutic targets of EOC. PMID- 27708549 TI - Success of tumorsphere isolation from WHO grade IV gliomas does not correlate with the weight of fresh tumor specimens: an immunohistochemical characterization of tumorsphere differentiation. AB - BACKGROUND: A trend of stage-by-stage increase in tumorsphere (TS) formation from glioma samples has been reported. Despite this trend, not all surgical specimens give rise to TSs, even World Health Organization (WHO) grade IV gliomas. Furthermore, it has been reported that differences in overall survival of primary glioblastoma patients depends on the propensity of their tumors to form TSs. However, the weights of fresh specimens vary from one surgical isolate to the next. METHODS: Accordingly, we evaluated the relationship between the weights of surgical specimens in WHO grade IV gliomas with the capacity to isolate TSs. Thirty-five fresh WHO grade IV glioma specimens were separated into two groups, based on whether they were positive or negative for TS isolation, and the relationship between TS isolation and weight of surgical specimens was assessed. RESULTS: We observed no significant difference in the weights of surgical samples in the two groups, and found that the optimal weight of specimens for TSs isolation was 500 mg. CONCLUSION: Thus, contrary to our expectations, the ability to isolate TSs from WHO grade IV glioma specimens was not related to the weight of fresh specimens. PMID- 27708550 TI - Relationship between TRAF6 and deterioration of HCC: an immunohistochemical and in vitro study. AB - OBJECTIVE: To explore the relationship between tumor necrosis factor receptor associated factor 6 (TRAF6) and the clinicopathological features in HCC as well as its biological function. METHODS: Totally, 412 liver tissues were collected, including 171 hepatocellular carcinoma (HCC) and their corresponding non-tumor tissues, 37 cirrhosis and 33 normal liver tissues. The expression of TRAF6 was assessed by immunohistochemistry. Then, analysis of the correlations between TRAF6 expression and clinicopathological parameters in HCC was conducted. Furtherer, in vitro experiments on HepG2 and Hep3B cells were performed to validate the biological function of TRAF6 on HCC cells. TRAF6 siRNA was transfected into HepG2 and Hep3B cell lines and TRAF6 expression was evaluated with RT-qPCR and western blot. The assays of cell viability, proliferation, apoptosis and caspase-3/7 activity were carried out to investigate the effects of TRAF6 on HCC cells with RNA interference. Cell viability was assessed with Cell Titer-Blue kit. Cell proliferation was tested with MTS kit. Cell apoptosis was checked through morphologic detection with fluorescence microscope, as well as caspase-3/7 activity was measured with fluorogenic substrate detection. RESULTS: The positive expression rate of TRAF6 protein was 49.7 % in HCC, significantly higher than that of normal liver (12.1 %), cirrhosis (21.6 %) and adjacent non cancerous tissues (36.3 %, all P < 0.05). Upregulated TRAF6 was detected in groups with metastasis (Z = -2.058, P = 0.04) and with low micro-vessel density (MVD) expression (Z = -2.813, P = 0.005). Spearman correlation analysis further showed that the expression of TRAF6 was positively correlated with distant metastasis (r = 0.158, P = 0.039) and negatively associated with MVD (r = -0.249, P = 0.004). Besides, knock-down of TRAF6 mRNA in HCC cell lines HepG2 and Hep3B both resulted in cell viability and proliferation inhibition, also cell apoptosis induction and caspase-3/7 activity activation. CONCLUSIONS: TRAF6 may contribute to metastasis and deterioration of the HCC via influencing cell growth and apoptosis. Thus, TRAF6 might become a predictive and therapeutic biomarker for HCC. PMID- 27708551 TI - Bone morphogenetic protein 2 (BMP2) induces growth suppression and enhances chemosensitivity of human colon cancer cells. AB - BACKGROUND: Molecular profiling of colorectal cancer (CRC) based on global gene expression has revealed multiple dysregulated signalling pathways associated with drug resistance and poor prognosis. However, the role of BMP2 signaling in CRC is not fully characterised. METHODS: Bioinformatics data analysis were conducted on the GSE21510 dataset. Leniviral technology was utilized to stably express BMP2 in the HCT116 CRC model. Gene expression profiling was conducted using Agilent microarray platform while data normalization and bioinformatics were conducted using GeneSpring software. Changes in gene expression were assessed using qRT PCR. AlamarBlue assay was used to assess cell viability in vitro. In vivo experiments were conducted using SCID mice. RESULTS: Our data revealed frequent downregulation of BMP2 in primary CRC tissues. Additionally, interrogation of publically available gene expression datasets revealed significant downregulation of BMP2 in metastatic recurrent compared to non-metastatic cancer (p = 0.02). Global gene expression analysis in CRC cells over-expressing BMP2 revealed multiple dysregulated pathways mostly affecting cell cycle and DNA damage response. Concordantly, lentiviral-mediated re-expression of BMP2 inhibited HCT116 CRC growth, sphere formation, clonogenic potential, cell migration, and sensitized CRC cells to 5-fluorouracil (5-FU) in vitro. Additionally, BMP2 inhibited CRC tumor formation in SCID mice. CONCLUSIONS: Our data revealed an inhibitory role for BMP2 in CRC, suggesting that restoration of BMP2 expression could be a potential therapeutic strategy for CRC.

AB - This meta-analysis compared the health-related quality of life (HRQL) of patients with allergic rhinitis (AR) and/or allergic asthma (AA) caused by perennial house dust mite (HDM) versus AR and/or AA caused by seasonal pollen allergy. Following a systematic search, the identified studies used the disease-specific rhinitis quality of life questionnaire or generic instruments (SF-36 and SF-12). Summary estimates obtained by meta-analysis showed that HRQL in patients with perennial HDM allergy was significantly worse than that of patients with seasonal pollen allergy, when measured by both disease-specific and generic HRQL instruments, and was reflected by an impact on both physical and mental health. A systematic review of cost data on AR and AA in selected European countries demonstrated that the majority of the economic burden was indirectly caused by high levels of absenteeism and presenteeism; there was little or no evidence of increasing or decreasing cost trends. Increased awareness of the detrimental effects of AR and/or AA on patients' HRQL and its considerable cost burden might encourage early diagnosis and treatment, in order to minimize the disease burden and ensure beneficial and cost-effective outcomes. PMID- 27708554 TI - Individually optimized stereotactic radiotherapy for pancreatic head tumors: A planning feasibility study. AB - AIM: Aim of this study was to perform a planning feasibility analysis of a 3 level dose prescription using an IMRT-SIB technique. BACKGROUND: Radiation therapy of locally advanced pancreatic cancer should administer a minimum dose to the duodenum and a very high dose to the vascular infiltration areas to improve the possibility of a radical resection. MATERIALS AND METHODS: Fifteen patients with pancreatic head adenocarcinoma and vascular involvement were included. The duodenal PTV (PTVd) was defined as the GTV overlapping the duodenal PRV. Vascular CTV (CTVv) was defined as the surface of contact or infiltration between the tumor and vessel plus a 5 mm margin. Vascular PTV (PTVv) was considered as the CTVv plus an anisotropic margin. The tumor PTV (PTVt) was defined as the GTV plus a margin including the PTVv and excluding the PTVd. The following doses were prescribed: 30 Gy (6 Gy/fraction) to PTVd, 37.5 Gy (7.5 Gy/fraction) to PTVt, and 45 Gy (9 Gy/fraction) to PTVv, respectively. Treatment was planned with an IMRT technique. RESULTS: The primary end-point (PTVv Dmean > 90%) was achieved in all patients. PTVv D98% > 90% was achieved in 6 patients (40%). OARs constraints were achieved in all patients. CONCLUSIONS: Although the PTVv D95% > 95% objective was achieved only in 40% of patients, the study showed that in 100% of patients it was possible to administer a strongly differentiated mean/median dose. Prospective trials based on clinical application of this strategy seem to be justified in selected patients without overlap between PTVd and PTVv. PMID- 27708553 TI - Proposal for new diagnostic criteria for DIC from the Japanese Society on Thrombosis and Hemostasis. AB - Disseminated intravascular coagulation (DIC) is a serious disease that, in the presence of underlying disease, causes persistent, generalized, marked coagulation activation. Early treatment based on an appropriate diagnosis is very important for improving patients' prognosis, to which end diagnostic criteria play a key role. Several criteria have been proposed, but each has its strengths and weaknesses, and improved criteria are needed. Widespread use of coagulofibrinolytic markers has elucidated that the pathology of DIC differs greatly as a function of the underlying disease. Thus, discriminating use of DIC diagnostic criteria that take underlying diseases into account is important. DIC diagnostic criteria that are well known in Japan include the Japanese Ministry of Health and Welfare's old DIC diagnostic criteria (JMHW criteria), the International Society on Thrombosis and Haemostasis's DIC diagnostic criteria (ISTH criteria), and the Japanese Association for Acute Medicine's acute-stage DIC diagnostic criteria (JAAM criteria). Those criteria have their respective drawbacks: the sensitivity of the ISTH criteria is poor, the JAAM criteria cannot be applied to all underlying diseases, and the JMHW criteria have poor sensitivity in the case of infections, do not use molecular markers, and result in misdiagnosis. The Japanese Society on Thrombosis and Hemostasis's newly proposed provisional draft DIC diagnostic criteria (new criteria) use diagnostic criteria classifications of "hematopoietic disorder type", "infectious type", and "basic type" based on the underlying pathology. For the hematopoietic disorder type the platelet count is omitted from the score, while for the infectious type, fibrinogen is omitted from the score. Also, points are added if the platelet count decreases with time. In the new criteria, molecular markers and antithrombin activity have been newly included, and as a countermeasure for misdiagnosis, 3 points are deducted if there is liver failure. In this paper, we discuss various problems encountered with DIC diagnosis, and we describe the new criteria together with the events that led to their creation. These new diagnostic criteria take into account the underlying diseases of wide area, and we expect that they will serve clinicians well due to the above adaptations and improvements. PMID- 27708555 TI - The Impact of School Social Support and Bullying Victimization on Psychological Distress among California Adolescents. AB - BACKGROUND AND PURPOSE: National reports showed that over 20% of high school students were victims of bullying, which could potentially lead to psychological problems. School social support may be protective against mental distress linked with victimization. This study examined the main and moderating effects of social support from adults in schools on non-specific serious psychological distress (SPD) related to victimization among California adolescents. METHODS: Utilizing the 2011-2012 California Health Interview Survey (CHIS), we analyzed a representative sample of 2,799 adolescents aged 12-17 years old. Logistic regression analyses were conducted modeling the odds of SPD in relation to school social support and victimization. RESULTS: Adolescents who were victimized were twice as likely to have SPD compared to non-victims. Higher level of social support from adults in schools was protective against SPD, but did not buffer the effect of bullying exposure. DISCUSSION: Findings from the present study suggested that adult support from schools can help with students' psychological problems but does not appear to prevent the psychological consequences of victimization. Additional intervention is needed, above and beyond social support, to prevent victimization and its psychological consequences. PMID- 27708556 TI - Precision medicine: from pharmacogenomics to pharmacoproteomics. AB - Disease progression and drug response may vary significantly from patient to patient. Fortunately, the rapid development of high-throughput 'omics' technologies has allowed for the identification of potential biomarkers that may aid in the understanding of the heterogeneities in disease development and treatment outcomes. However, mechanistic gaps remain when the genome or the proteome are investigated independently in response to drug treatment. In this article, we discuss the current status of pharmacogenomics in precision medicine and highlight the needs for concordant analysis at the proteome and metabolome levels via the more recently-evolved fields of pharmacoproteomics, toxicoproteomics, and pharmacometabolomics. Integrated 'omics' investigations will be critical in piecing together targetable mechanisms of action for both drug development and monitoring of therapy in order to fully apply precision medicine to the clinic. PMID- 27708557 TI - Plasma degradome affected by variable storage of human blood. AB - BACKGROUND: The successful application of-omics technologies in the discovery of novel biomarkers and targets of therapeutic interventions is facilitated by large collections of well curated clinical samples stored in bio banks. Mining the plasma proteome holds promise to improve our understanding of disease mechanisms and may represent a source of biomarkers. However, a major confounding factor for defining disease-specific proteomic signatures in plasma is the variation in handling and processing of clinical samples leading to protein degradation. To address this, we defined a plasma proteolytic signature (degradome) reflecting pre-analytical variability in blood samples that remained at ambient temperature for different time periods after collection and prior to processing. METHODS: We obtained EDTA blood samples from five healthy volunteers (n = 5), and blood tubes remained at ambient temperature for 30 min, 8, 24 and 48 h prior to centrifugation and isolation of plasma. Naturally occurred peptides derived from plasma samples were compared by label-free quantitative LC-MS/MS. To profile protein degradation, we analysed pooled plasma samples at T = 30 min and 48 h using PROTOMAP analysis. The proteolytic pattern of selected protein candidates was further validated by immunoblotting. RESULTS: A total of 820 plasma proteins were surveyed by PROTOMAP, and for 4 % of these, marked degradation was observed. We show distinct proteolysis patterns for talin-1, coagulation factor XI, complement protein C1r, C3, C4 and thrombospondin, and several proteins including S100A8, A9, annexin A1, profiling-1 and platelet glycoprotein V are enriched after 48 h blood storage at ambient temperature. In particular, thrombospondin protein levels increased after 8 h and proteolytic fragments appeared after 24 h storage time. CONCLUSIONS: The overall impact of blood storage at ambient temperature for variable times on the plasma proteome and degradome is relatively minor, but in some cases can cause a potential bias in identifying and assigning relevant proteomic markers. The observed effects on the plasma proteome and degradome are predominantly triggered by limited leucocyte and platelet cell activation due to blood handling and storage. The baseline plasma degradome signature presented here can help filtering candidate protein markers relevant for clinical biomarker studies.

PMID- 27708559 TI - Does Prenatal Valproate Interact with a Genetic Reduction in the Serotonin Transporter? A Rat Study on Anxiety and Cognition. AB - There is ample evidence that prenatal exposure to valproate (or valproic acid, VPA) enhances the risk of developing Autism Spectrum Disorders (ASD). In line with this, a single injection of VPA induces a multitude of ASD-like symptoms in animals, such as rats and mice. However, there is equally strong evidence that genetic factors contribute significantly to the risk of ASD and indeed, like most other psychiatric disorders, ASD is now generally thought to results from an interaction between genetic and environmental factors. Given that VPA significantly impacts on the serotonergic system, and serotonin has strong biochemical and genetic links to ASD, we aimed to investigate the interaction between genetic reduction in the serotonin transporter and prenatal valproate administration. More specifically, we exposed both wildtype (SERT+/+) rats and rats heterozygous for the serotonin transporter deletion (SERT+/-) to a single injection of 400 mg/kg VPA at gestational day (GD) 12. The offspring, in adulthood, was assessed in four different tests: Elevated Plus Maze and Novelty Suppressed Feeding as measures for anxiety and prepulse inhibition (PPI) and latent inhibition as measures for cognition and information processing. The results show that prenatal VPA significantly increased anxiety in both paradigm, reduced PPI and reduced conditioning in the latent inhibition paradigm. However, we failed to find a significant gene-environment interaction. We propose that this may be related to the timing of the VPA injection and suggest that whereas GD12 might be optimal for affecting normal rat, rats with a genetically compromised serotonergic system may be more sensitive to VPA at earlier time points during gestation. Overall our data are the first to investigate gene * environmental interactions in a genetic rat model for ASD and suggest that timing may be of crucial importance to the long-term outcome. PMID- 27708560 TI - Targeted Re-Sequencing Approach of Candidate Genes Implicates Rare Potentially Functional Variants in Tourette Syndrome Etiology. AB - Although the genetic basis of Tourette Syndrome (TS) remains unclear, several candidate genes have been implicated. Using a set of 382 TS individuals of European ancestry we investigated four candidate genes for TS (HDC, SLITRK1, BTBD9, and SLC6A4) in an effort to identify possibly causal variants using a targeted re-sequencing approach by next generation sequencing technology. Identification of possible disease causing variants under different modes of inheritance was performed using the algorithms implemented in VAAST. We prioritized variants using Variant ranker and validated five rare variants via Sanger sequencing in HDC and SLITRK1, all of which are predicted to be deleterious. Intriguingly, one of the identified variants is in linkage disequilibrium with a variant that is included among the top hits of a genome wide association study for response to citalopram treatment, an antidepressant drug with off-label use also in obsessive compulsive disorder. Our findings provide additional evidence for the implication of these two genes in TS susceptibility and the possible role of these proteins in the pathobiology of TS should be revisited. PMID- 27708562 TI - Embryonic Cell Grafts in a Culture Model of Spinal Cord Lesion: Neuronal Relay Formation Is Essential for Functional Regeneration. AB - Presently there exists no cure for spinal cord injury (SCI). However, transplantation of embryonic tissue into spinal cord (SC) lesions resulted in axon outgrowth across the lesion site and some functional recovery, fostering hope for future stem cell therapies. Although in vivo evidence for functional recovery is given, the exact cellular mechanism of the graft support remains elusive: either the grafted cells provide a permissive environment for the host tissue to regenerate itself or the grafts actually integrate functionally into the host neuronal network reconnecting the separated SC circuits. We tested the two hypotheses in an in vitro SC lesion model that is based on propagation of activity between two rat organotypic SC slices in culture. Transplantation of dissociated cells from E14 rat SC or forebrain (FB) re-established the relay of activity over the lesion site and thus, provoked functional regeneration. Combining patch-clamp recordings from transplanted cells with network activity measurements from the host tissue on multi-electrode arrays (MEAs) we here show that neurons differentiate from the grafted cells and integrate into the host circuits. Optogenetic silencing of neurons developed from transplanted embryonic mouse FB cells provides clear evidence that they replace the lost neuronal connections to relay and synchronize activity between the separated SC circuits. In contrast, transplantation of neurospheres (NS) induced neither the differentiation of mature neurons from the grafts nor an improvement of functional regeneration. Together these findings suggest, that the formation of neuronal relays from grafted embryonic cells is essential to re-connect segregated SC circuits. PMID- 27708561 TI - Protective Microglia and Their Regulation in Parkinson's Disease. AB - Microglia-mediated neuroinflammation is a hallmark of Parkinson's disease (PD). In the brains of patients with PD, microglia have both neurotoxic and neuroprotective effects, depending on their activation state. In this review, we focus on recent research demonstrating the neuroprotective role of microglia in PD. Accumulating evidence indicates that the protective mechanisms of microglia may result from their regulation of transrepression pathways via nuclear receptors, anti-inflammatory responses, neuron-microglia crosstalk, histone modification, and microRNA regulation. All of these mechanisms work together to suppress the production of neurotoxic inflammatory components. However, during the progression of PD, the detrimental effects of inflammation overpower the protective actions of microglia. Therefore, an in-depth exploration of the mechanisms underlying microglial neuroprotection, and a means of promoting the transformation of microglia to the protective phenotype, are urgently needed for the treatment of PD.

PMID- 27708563 TI - Basal Dendrites of Layer-III Pyramidal Neurons do not Scale with Changes in Cortical Magnification Factor in Macaque Primary Visual Cortex. AB - Neurons in the mammalian primary visual cortex (V1) are systematically arranged across the cortical surface according to the location of their receptive fields (RFs), forming a visuotopic (or retinotopic) map. Within this map, the foveal visual field is represented by a large cortical surface area, with increasingly peripheral visual fields gradually occupying smaller cortical areas. Although cellular organization in the retina, such as the spatial distribution of ganglion cells, can partially account for the eccentricity-dependent differences in the size of cortical representation, whether morphological differences exist across V1 neurons representing different eccentricities is unclear. In particular, morphological differences in dendritic field diameter might contribute to the magnified representation of the central visual field. Here, we addressed this question by measuring the basal dendritic arbors of pyramidal neurons of layer IIIC and adjoining layer III sublayers (in the Hassler's nomenclature) in macaque V1. We labeled layer-III pyramidal neurons at various retinotopic positions in V1 by injecting lightly fixed brain tissue with intracellular dye, and then compared dendritic morphology across regions in the retinotopic map representing 0-20 degrees of eccentricity. The dendritic field area, total dendritic length, number of principal dendrites, branching complexity, spine density and total number of spines were all consistent across different retinotopic regions of V1. These results indicate that dendrites in layer-III pyramidal neurons are relatively homogeneous according to these morphometric parameters irrespective of their locations in this portion of the retinotopic map. The homogeneity of dendritic morphology in these neurons suggests that the emphasis of central visual field representation is not attributable to changes in the basal dendritic arbors of pyramidal neurons in layer III, but is likely the result of successive processes earlier in the retino-geniculo-striate pathway. PMID- 27708565 TI - Non-parametric Algorithm to Isolate Chunks in Response Sequences. AB - Chunking consists in grouping items of a sequence into small clusters, named chunks, with the assumed goal of lessening working memory load. Despite extensive research, the current methods used to detect chunks, and to identify different chunking strategies, remain discordant and difficult to implement. Here, we propose a simple and reliable method to identify chunks in a sequence and to determine their stability across blocks. This algorithm is based on a ranking method and its major novelty is that it provides concomitantly both the features of individual chunk in a given sequence, and an overall index that quantifies the chunking pattern consistency across sequences. The analysis of simulated data confirmed the validity of our method in different conditions of noise, chunk lengths and chunk numbers; moreover, we found that this algorithm was particularly efficient in the noise range observed in real data, provided that at least 4 sequence repetitions were included in each experimental block. Furthermore, we applied this algorithm to actual reaction time series gathered from 3 published experiments and were able to confirm the findings obtained in the original reports. In conclusion, this novel algorithm is easy to implement, is robust to outliers and provides concurrent and reliable estimation of chunk position and chunking dynamics, making it useful to study both sequence-specific and general chunking effects. The algorithm is available at: https://github.com/artipago/Non-parametric-algorithm-to-isolate-chunks-in response-sequences. PMID- 27708566 TI - Is the Sensorimotor Cortex Relevant for Speech Perception and Understanding? An Integrative Review. AB - In the neuroscience of language, phonemes are frequently described as multimodal units whose neuronal representations are distributed across perisylvian cortical regions, including auditory and sensorimotor areas. A different position views phonemes primarily as acoustic entities with posterior temporal localization, which are functionally independent from frontoparietal articulatory programs. To address this current controversy, we here discuss experimental results from functional magnetic resonance imaging (fMRI) as well as transcranial magnetic stimulation (TMS) studies. On first glance, a mixed picture emerges, with earlier research documenting neurofunctional distinctions between phonemes in both temporal and frontoparietal sensorimotor systems, but some recent work seemingly failing to replicate the latter. Detailed analysis of methodological differences between studies reveals that the way experiments are set up explains whether sensorimotor cortex maps phonological information during speech perception or not. In particular, acoustic noise during the experiment and 'motor noise' caused by button press tasks work against the frontoparietal manifestation of phonemes. We highlight recent studies using sparse imaging and passive speech perception tasks along with multivariate pattern analysis (MVPA) and especially representational similarity analysis (RSA), which succeeded in separating acoustic-phonological from general-acoustic processes and in mapping specific phonological information on temporal and frontoparietal regions. The question about a causal role of sensorimotor cortex on speech perception and understanding is addressed by reviewing recent TMS studies. We conclude that frontoparietal cortices, including ventral motor and somatosensory areas, reflect phonological information during speech perception and exert a causal influence on language understanding. PMID- 27708568 TI - Improving Production of Treated and Untreated Verbs in Aphasia: A Meta-Analysis. AB - Background: Demographic and clinical predictors of aphasia recovery have been identified in the literature. However, little attention has been devoted to identifying and distinguishing predictors of improvement for different outcomes, e.g., production of treated vs. untreated materials. These outcomes may rely on different mechanisms, and therefore be predicted by different variables. Furthermore, treatment features are not typically accounted for when studying predictors of aphasia recovery. This is partly due to the small numbers of cases reported in studies, but also to limitations of data analysis techniques usually employed. Method: We reviewed the literature on predictors of aphasia recovery, and conducted a meta-analysis of single-case studies designed to assess the efficacy of treatments for verb production. The contribution of demographic, clinical, and treatment-related variables was assessed by means of Random Forests (a machine-learning technique used in classification and regression). Two outcomes were investigated: production of treated (for 142 patients) and untreated verbs (for 166 patients). Results: Improved production of treated verbs was predicted by a three-way interaction of pre-treatment scores on tests for verb comprehension and word repetition, and the frequency of treatment sessions. Improvement in production of untreated verbs was predicted by an interaction including the use of morphological cues, presence of grammatical impairment, pre treatment scores on a test for noun comprehension, and frequency of treatment sessions. Conclusion: Improvement in the production of treated verbs occurs frequently. It may depend on restoring access to and/or knowledge of lexeme representations, and requires relative sparing of semantic knowledge (as measured by verb comprehension) and phonological output abilities (including working memory, as measured by word repetition). Improvement in the production of untreated verbs has not been reported very often. It may depend on the nature of impaired language representations, and the type of knowledge engaged by treatment: it is more likely to occur where abstract features (semantic and/or grammatical) are damaged and treated. PMID- 27708567 TI - Increased Sleep Depth in Developing Neural Networks: New Insights from Sleep Restriction in Children. AB - Brain networks respond to sleep deprivation or restriction with increased sleep depth, which is quantified as slow-wave activity (SWA) in the sleep electroencephalogram (EEG). When adults are sleep deprived, this homeostatic response is most pronounced over prefrontal brain regions. However, it is unknown how children's developing brain networks respond to acute sleep restriction, and whether this response is linked to myelination, an ongoing process in childhood that is critical for brain development and cortical integration. We implemented a bedtime delay protocol in 5- to 12-year-old children to obtain partial sleep restriction (1-night; 50% of their habitual sleep). High-density sleep EEG was assessed during habitual and restricted sleep and brain myelin content was obtained using mcDESPOT magnetic resonance imaging. The effect of sleep restriction was analyzed using statistical non-parametric mapping with supra threshold cluster analysis. We observed a localized homeostatic SWA response following sleep restriction in a specific parieto-occipital region. The restricted/habitual SWA ratio was negatively associated with myelin water fraction in the optic radiation, a developing fiber bundle. This relationship occurred bilaterally over parieto-temporal areas and was adjacent to, but did not overlap with the parieto-occipital region showing the most pronounced homeostatic SWA response. These results provide evidence for increased sleep need in posterior neural networks in children. Sleep need in parieto-temporal areas is related to myelin content, yet it remains speculative whether age-related myelin growth drives the fading of the posterior homeostatic SWA response during the transition to adulthood. Whether chronic insufficient sleep in the sensitive period of early life alters the anatomical generators of deep sleep slow-waves is an important unanswered question. PMID- 27708569 TI - Modeling and Theories of Pathophysiology and Physiology of the Basal Ganglia Thalamic-Cortical System: Critical Analysis. AB - Theories impact the movement disorders clinic, not only affecting the development of new therapies but determining how current therapies are used. Models are theories that are procedural rather than declarative. Theories and models are important because, as argued by Kant, one cannot know the thing-in-itself (das Ding an sich) and only a model is knowable. Further, biological variability forces higher level abstraction relevant for all variants. It is that abstraction that is raison d'etre of theories and models. Theories "connect the dots" to move from correlation to causation. The necessity of theory makes theories helpful or counterproductive. Theories and models of the pathophysiology and physiology of the basal ganglia-thalamic-cortical system do not spontaneously arise but have a history and consequently are legacies. Over the last 40 years, numerous theories and models of the basal ganglia have been proposed only to be forgotten or dismissed, rarely critiqued. It is not harsh to say that current popular theories positing increased neuronal activities in the Globus Pallidus Interna (GPi), excessive beta oscillations and increased synchronization not only fail to provide an adequate explication but are inconsistent with many observations. It is likely that their shared intellectual and epistemic inheritance plays a factor in their shared failures. These issues are critically examined. How one is to derive theories and models and have hope these will be better is explored as well. PMID- 27708570 TI - Effects of Age on Long Term Memory for Degraded Speech. AB - Prior research suggests that acoustical degradation impacts encoding of items into memory, especially in elderly subjects. We here aimed to investigate whether acoustically degraded items that are initially encoded into memory are more prone to forgetting as a function of age. Young and old participants were tested with a vocoded and unvocoded serial list learning task involving immediate and delayed free recall. We found that degraded auditory input increased forgetting of previously encoded items, especially in older participants. We further found that working memory capacity predicted forgetting of degraded information in young participants. In old participants, verbal IQ was the most important predictor for forgetting acoustically degraded information. Our data provide evidence that acoustically degraded information, even if encoded, is especially vulnerable to forgetting in old age. PMID- 27708571 TI - Error-Related Negativity and the Misattribution of State-Anxiety Following Errors: On the Reproducibility of Inzlicht and Al-Khindi (). AB - In their innovative study, Inzlicht and Al-Khindi (2012) demonstrated that participants who were allowed to misattribute their arousal and negative affect induced by errors to a placebo beverage had a reduced error-related negativity (ERN/Ne) compared to controls not being allowed to misattribute their arousal following errors. These results contribute to the ongoing debate that affect and motivation are interwoven with the cognitive processing of errors. Evidence that the misattribution of negative affect modulates the ERN/Ne is essential for understanding the mechanisms behind ERN/Ne. Therefore, and because of the growing debate on reproducibility of empirical findings, we aimed at replicating the misattribution effects on the ERN/Ne in a go/nogo task. Students were randomly assigned to a misattribution group (n = 48) or a control group (n = 51). Participants of the misattribution group consumed a beverage said to have side effects that would increase their physiological arousal, so that they could misattribute the negative affect induced by errors to the beverage. Participants of the control group correctly believed that the beverage had no side effects. As Inzlicht and Al-Khindi (2012), we did not observe performance differences between both groups. However, ERN/Ne differences between misattribution and control group could not be replicated, although the statistical power of the replication study was high. Evidence regarding the replication of performance and the non replication of ERN/Ne findings was confirmed by Bayesian statistics. PMID- 27708572 TI - Drifting States and Synchronization Induced Chaos in Autonomous Networks of Excitable Neurons. AB - The study of balanced networks of excitatory and inhibitory neurons has led to several open questions. On the one hand it is yet unclear whether the asynchronous state observed in the brain is autonomously generated, or if it results from the interplay between external drivings and internal dynamics. It is also not known, which kind of network variabilities will lead to irregular spiking and which to synchronous firing states. Here we show how isolated networks of purely excitatory neurons generically show asynchronous firing whenever a minimal level of structural variability is present together with a refractory period. Our autonomous networks are composed of excitable units, in the form of leaky integrators spiking only in response to driving currents, remaining otherwise quiet. For a non-uniform network, composed exclusively of excitatory neurons, we find a rich repertoire of self-induced dynamical states. We show in particular that asynchronous drifting states may be stabilized in purely excitatory networks whenever a refractory period is present. Other states found are either fully synchronized or mixed, containing both drifting and synchronized components. The individual neurons considered are excitable and hence do not dispose of intrinsic natural firing frequencies. An effective network-wide distribution of natural frequencies is however generated autonomously through self-consistent feedback loops. The asynchronous drifting state is, additionally, amenable to an analytic solution. We find two types of asynchronous activity, with the individual neurons spiking regularly in the pure drifting state, albeit with a continuous distribution of firing frequencies. The activity of the drifting component, however, becomes irregular in the mixed state, due to the periodic driving of the synchronized component. We propose a new tool for the study of chaos in spiking neural networks, which consists of an analysis of the time series of pairs of consecutive interspike intervals. In this space, we show that a strange attractor with a fractal dimension of about 1.8 is formed in the mentioned mixed state. PMID- 27708573 TI - Automated Neuroanatomical Relation Extraction: A Linguistically Motivated Approach with a PVT Connectivity Graph Case Study. AB - Identifying the relations among different regions of the brain is vital for a better understanding of how the brain functions. While a large number of studies have investigated the neuroanatomical and neurochemical connections among brain structures, their specific findings are found in publications scattered over a large number of years and different types of publications. Text mining techniques have provided the means to extract specific types of information from a large number of publications with the aim of presenting a larger, if not necessarily an exhaustive picture. By using natural language processing techniques, the present paper aims to identify connectivity relations among brain regions in general and relations relevant to the paraventricular nucleus of the thalamus (PVT) in particular. We introduce a linguistically motivated approach based on patterns defined over the constituency and dependency parse trees of sentences. Besides the presence of a relation between a pair of brain regions, the proposed method also identifies the directionality of the relation, which enables the creation and analysis of a directional brain region connectivity graph. The approach is evaluated over the manually annotated data sets of the WhiteText Project. In addition, as a case study, the method is applied to extract and analyze the connectivity graph of PVT, which is an important brain region that is considered to influence many functions ranging from arousal, motivation, and drug-seeking behavior to attention. The results of the PVT connectivity graph show that PVT may be a new target of research in mood assessment.

PMID- 27708575 TI - Physical Exercise Preserves Adult Visual Plasticity in Mice and Restores it after a Stroke in the Somatosensory Cortex. AB - The primary visual cortex (V1) is widely used to study brain plasticity, which is not only crucial for normal brain function, such as learning and memory, but also for recovery after brain injuries such as stroke. In standard cage (SC) raised mice, experience-dependent ocular dominance (OD) plasticity in V1 declines with age and is compromised by a lesion in adjacent and distant cortical regions. In contrast, mice raised in an enriched environment (EE), exhibit lifelong OD plasticity and are protected from losing OD plasticity after a stroke-lesion in the somatosensory cortex. Since SC mice with an access to a running wheel (RW) displayed preserved OD plasticity during aging, we investigated whether physical exercise might also provide a plasticity promoting effect after a cortical stroke. To this end, we tested if adult RW-raised mice preserved OD plasticity after stroke and also if short-term running after stroke restored OD plasticity to SC mice. Indeed, unlike mice without a RW, adult RW mice continued to show OD plasticity even after stroke, and a 2 weeks RW experience after stroke already restored lost OD plasticity. Additionally, the experience-enabled increase of the spatial frequency and contrast threshold of the optomotor reflex of the open eye, normally lost after a stroke, was restored in both groups of RW mice. Our data suggest that physical exercise alone can not only preserve visual plasticity into old age, but also restore it after a cortical stroke.

AB - Background: Cerebral cavernous malformations (CCMs) are common vascular malformations that predominantly arise in the central nervous system and are mainly characterized by enlarged vascular cavities without intervening brain parenchyma. Familial CCMs (FCCMs) is inherited in an autosomal dominant pattern with incomplete penetrance and variable symptoms. Methods: Mutations of three pathogenic genes, CCM1, CCM2, and CCM3, were investigated by direct DNA sequencing in a Chinese family with multiple CCM lesions. Results: Four heterozygous variants in the CCM2 gene, including one deletion (c.95delC), a missense mutation (c.358G>A, p.V120I), one silent mutation (c.915G>A, p.T305T), and a substitution (c. *1452 T>C), were identified in the subjects with multiple CCM lesions, but not in a healthy sibling. Among these variants, the c.95delC deletion is a novel mutation which is expected to cause a premature termination codon. It is predicted to produce a truncated CCM2 protein lacking the PTB and C terminal domains, thus disrupting the molecular functions of CCM2. Conclusions: The novel truncating mutation in the CCM2 gene, c.95delC, may be responsible for multiple CCM lesions in a part of FCCM. In addition, it may represent a potential genetic biomarker for early diagnosis of FCCM. PMID- 27708577 TI - Neuroanatomical Alterations in Tinnitus Assessed with Magnetic Resonance Imaging. AB - Previous studies of anatomical changes associated with tinnitus have provided inconsistent results, with some showing significant cortical and subcortical changes, while others have found effects due to hearing loss, but not tinnitus. In this study, we examined changes in brain anatomy associated with tinnitus using anatomical scans from 128 participants with tinnitus and hearing loss, tinnitus with clinically normal hearing, and non-tinnitus controls with clinically normal hearing. The groups were matched for hearing loss, age and gender. We employed voxel- and surface-based morphometry (SBM) to investigate gray and white matter volume and thickness within regions-of-interest (ROI) that were based on the results of previous studies. The largest overall effects were found for age, gender, and hearing loss. With regard to tinnitus, analysis of ROI revealed numerous small increases and decreases in gray matter and thickness between tinnitus and non-tinnitus controls, in both cortical and subcortical structures. For whole brain analysis, the main tinnitus-related significant clusters were found outside sensory auditory structures. These include a decrease in cortical thickness for the tinnitus group compared to controls in the left superior frontal gyrus (SFG), and a decrease in cortical volume with hearing loss in left Heschl's gyrus (HG). For masked analysis, we found a decrease in gray matter volume in the right Heschle's gyrus for the tinnitus group compared to the controls. We found no changes in the subcallosal region as reported in some previous studies. Overall, while some of the morphological differences observed in this study are similar to previously published findings, others are entirely different or even contradict previous results. We highlight other discrepancies among previous results and the increasing need for a more precise subtyping of the condition. PMID- 27708578 TI - Adherence and Patients' Experiences with the Use of Capecitabine in Daily Practice. AB - Introduction: Capecitabine is a widely prescribed oral anticancer agent. We studied medication adherence and explored its use in daily practice from a patients' perspective. Patients and Methods: Patients (n = 92) starting capecitabine were followed up to five 3-week cycles. Adherence was assessed using a pill count, pharmacy data and dosing information from the patients' medical file. Self-reported adherence was measured using the Medication Adherence Report Scale (MARS). At baseline and during week 2 of cycles 1, 3, and 5, patients filled out questionnaires about quality of life, symptoms, attitude toward medicines and disease and use in daily practice. Simultaneously, blood samples were taken to determine the area under the curve (AUC) of 5'-deoxy-5 fluorouridine (5'-DFUR), 5-fluorouracil (5-FU), and alpha-fluoro-beta-alanine (FBAL) by a population pharmacokinetic model. Associations between AUCs and patient-reported symptoms were tested for cycles 3 and 5. Results: Most patients (84/92; 91%) had an adherence rate of >=95 and <= 105%. The percentage of patients reporting any non-adherence behavior measured with MARS increased from 16% at cycle 1 to 29% at cycle 5. Symptoms were reported frequently and the dosing regimen was adjusted by the physician at least once in 62% of patients. In multivariate analysis the probability of an adjustment increased with the number of co-medication (OR 1.19, 95% CI: 1.03-1.39) and a stronger emotional response to the disease (OR 1.32, 95% CI: 1.10-1.59). The AUC of 5'-DFUR was associated with weight loss (OR 1.10, 95% CI: 1.01-1.19), AUC of FBAL with hand-foot syndrome (OR 0.90, 95% CI: 0.83-0.99), rhinorrhea (OR 1.21, 95% CI: 1.03-1.42 weight loss (OR 1.09, 95% CI: 1.00-1.20) and depression (OR 0.90, 95% CI: 0.82 0.99). Side effects were reported by one third of patients as the reason to discontinue treatment. Conclusion: Adherence to capecitabine was generally high. Nevertheless, adherence measured with MARS decreased over time Adherence management to support implementation of correct capecitabine use is specifically relevant in longer term treatment. In addition, it appears that adverse event management is important to support persistence. With the extending armamentarium of oral targeted anticancer agents and prolonged treatment duration, we expect the issue of medication adherence of increasing importance in oncology. PMID- 27708580 TI - Innovative Strategies to Develop Chemical Categories Using a Combination of Structural and Toxicological Properties. AB - Interest is increasing in the development of non-animal methods for toxicological evaluations. These methods are however, particularly challenging for complex toxicological endpoints such as repeated dose toxicity. European Legislation, e.g., the European Union's Cosmetic Directive and REACH, demands the use of alternative methods. Frameworks, such as the Read-across Assessment Framework or the Adverse Outcome Pathway Knowledge Base, support the development of these methods. The aim of the project presented in this publication was to develop substance categories for a read-across with complex endpoints of toxicity based on existing databases. The basic conceptual approach was to combine structural similarity with shared mechanisms of action. Substances with similar chemical structure and toxicological profile form candidate categories suitable for read across. We combined two databases on repeated dose toxicity, RepDose database, and ELINCS database to form a common database for the identification of categories. The resulting database contained physicochemical, structural, and toxicological data, which were refined and curated for cluster analyses. We applied the Predictive Clustering Tree (PCT) approach for clustering chemicals based on structural and on toxicological information to detect groups of chemicals with similar toxic profiles and pathways/mechanisms of toxicity. As many of the experimental toxicity values were not available, this data was imputed by predicting them with a multi-label classification method, prior to clustering. The clustering results were evaluated by assessing chemical and toxicological similarities with the aim of identifying clusters with a concordance between structural information and toxicity profiles/mechanisms. From these chosen clusters, seven were selected for a quantitative read-across, based on a small ratio of NOAEL of the members with the highest and the lowest NOAEL in the cluster (< 5). We discuss the limitations of the approach. Based on this analysis we propose improvements for a follow-up approach, such as incorporation of metabolic information and more detailed mechanistic information. The software enables the user to allocate a substance in a cluster and to use this information for a possible read- across. The clustering tool is provided as a free web service, accessible at http://mlc-reach.informatik.uni-mainz.de. PMID- 27708579 TI - Pharmacogenomics of Prostaglandin and Leukotriene Receptors. AB - Individual genetic background together with environmental effects are thought to be behind many human complex diseases. A number of genetic variants, mainly single nucleotide polymorphisms (SNPs), have been shown to be associated with various pathological and inflammatory conditions, representing potential therapeutic targets. Prostaglandins (PTGs) and leukotrienes (LTs) are eicosanoids derived from arachidonic acid and related polyunsaturated fatty acids that participate in both normal homeostasis and inflammatory conditions. These bioactive lipid mediators are synthesized through two major multistep enzymatic pathways: PTGs by cyclooxygenase and LTs by 5-lipoxygenase. The main physiological effects of PTGs include vasodilation and vascular leakage (PTGE2); mast cell maturation, eosinophil recruitment, and allergic responses (PTGD2); vascular and respiratory smooth muscle contraction (PTGF2), and inhibition of platelet aggregation (PTGI2). LTB4 is mainly involved in neutrophil recruitment, vascular leakage, and epithelial barrier function, whereas cysteinyl LTs (CysLTs) (LTC4, LTD4, and LTE4) induce bronchoconstriction and neutrophil extravasation, and also participate in vascular leakage. PTGs and LTs exert their biological functions by binding to cognate receptors, which belong to the seven transmembrane, G protein-coupled receptor superfamily. SNPs in genes encoding these receptors may influence their functionality and have a role in disease susceptibility and drug treatment response. In this review we summarize SNPs in PTGs and LTs receptors and their relevance in human diseases. We also provide information on gene expression. Finally, we speculate on future directions for this topic. PMID- 27708581 TI - Activation of Endothelial Pro-resolving Anti-Inflammatory Pathways by Circulating Microvesicles from Non-muscular Myosin Light Chain Kinase-Deficient Mice. AB - Microvesicles, small membrane vesicles released from cells, have beneficial and/or deleterious effects in sepsis. We previously reported that non-muscle myosin light chain kinase (nmMLCK) deletion protects mice against endotoxic shock by reducing inflammation. Here, we have evaluated the consequences of nmMLCK deletion on microvesicle phenotypes and their effects on mouse aortic endothelial cells in association with vascular inflammation and endothelial dysfunction during endotoxic shock induced by lipopolysaccharide in mice. Treatment with lipopolysaccharide induced an increase in levels of circulating microvesicles in wild type but not in nmMLCK-deficient mice. Microvesicles from nmMLCK-deficient mice (MVsnmMLCK-/-) prevented the inflammatory effects of lipopolysaccharide with concomitant increase of anti- inflammatory and reduction of pro-inflammatory secretome in mouse aortic endothelial cells. In addition, MVsnmMLCK-/- reduced the efficacy of lipopolysaccharide to increase aortic oxidative and nitrosative stresses as well as macrophage infiltration in the aorta. Moreover, MVsnmMLCK-/- prevented ex vivo endothelial dysfunction, vascular hyporeactivity, and in vivo overproduction of nitric oxide in heart and liver in response to lipopolysaccharide. Altogether, these findings provide evidence that nmMLCK deletion generates circulating microvesicles displaying protective effects by activating endothelial pro-resolving anti-inflammatory pathways allowing the effective down-regulation of oxidative and nitrative stresses associated with endotoxic shock. Thus, nmMLCK plays a pivotal role in susceptibility to sepsis via the control of cellular activation and release of circulating microvesicles. PMID- 27708582 TI - High-density Lipoproteins and Apolipoprotein A-I: Potential New Players in the Prevention and Treatment of Lung Disease. AB - Apolipoprotein A-I (apoA-I) and high-density lipoproteins (HDL) mediate reverse cholesterol transport out of cells. Furthermore, HDL has additional protective functions, which include anti-oxidative, anti-inflammatory, anti-apoptotic, and vasoprotective effects. In contrast, HDL can become dysfunctional with a reduction in both cholesterol efflux and anti-inflammatory properties in the setting of disease or the acute phase response. These paradigms are increasingly being recognized to be active in the pulmonary system, where apoA-I and HDL have protective effects in normal lung health, as well as in a variety of disease states, including acute lung injury (ALI), asthma, chronic obstructive pulmonary disease, lung cancer, pulmonary arterial hypertension, pulmonary fibrosis, and viral pneumonia. Similar to observations in cardiovascular disease, however, HDL may become dysfunctional and contribute to disease pathogenesis in respiratory disorders. Furthermore, synthetic apoA-I mimetic peptides have been shown to have protective effects in animal models of ALI, asthma, pulmonary hypertension, and influenza pneumonia. These findings provide evidence to support the concept that apoA-I mimetic peptides might be developed into a new treatment that can either prevent or attenuate the manifestations of lung diseases, such as asthma. Thus, the lung is positioned to take a page from the cardiovascular disease playbook and utilize the protective properties of HDL and apoA-I as a novel therapeutic approach. PMID- 27708583 TI - Preparation and Characterization of Loperamide-Loaded Dynasan 114 Solid Lipid Nanoparticles for Increased Oral Absorption In the Treatment of Diarrhea. AB - The aim of the project was to assemble two optimum solid lipid nanoparticle (SLN) formulations for oral delivery of loperamide (LPM) to treat different types of diarrhea, and to evaluate their release profiles in vitro and pharmacokinetic properties in vivo. In this work, glyceryl trimyristate (Dynasan 114) nanoparticles containing the drug LPM and sodium cholate as a stabilizer were prepared using a modified solvent evaporation technique. Two LPM-loaded SLNs, namely LPM-SLN-1 (LPM-SLN with a high ratio rate of lipid to drug) and LPM-SLN-2 (LPM-SLN with a low ratio rate of lipid to drug), were prepared by the solvent evaporation method. A change in the lipid concentration affects the characteristics of LPM-SLNs. The average sizes of the LPM-SLNs were 303 +/- 18 nm and 519 +/- 36 nm, separately, as analyzed by dynamic light scattering. The LPM SLNs were found to be round with a smooth surface, as observed using a transmission electron microscope and a scanning electron microscope. The average encapsulation efficiencies were 87 +/- 3.78% w/w and 84 +/- 5.17%, accordingly. In the in vitro release experiments, LPM-SLNs showed a continuous release profile of LPM without any burst release. The oral bioavailability of LPM-SLNs was analyzed using Wistar rats. The relative bioavailabilities of LPM-SLNs were 227 and 153%, respectively, as compared that of the LPM tablet. There was no difference in the Tmax between LPM-SLN-2 and the LPM tablet. In conclusion, LPM SLN-1 significantly improved the oral bioavailability of LPM, while LPM-SLN-2 having the same swift action as the LPM tablet. These results demonstrate the potential of LPM-SLNs in the oral delivery of LPM to treat different types of diarrhea. PMID- 27708584 TI - Multiscale Mathematical Modeling in Dental Tissue Engineering: Toward Computer Aided Design of a Regenerative System Based on Hydroxyapatite Granules, Focussing on Early and Mid-Term Stiffness Recovery. AB - We here explore for the very first time how an advanced multiscale mathematical modeling approach may support the design of a provenly successful tissue engineering concept for mandibular bone. The latter employs double-porous, potentially cracked, single millimeter-sized granules packed into an overall conglomerate-type scaffold material, which is then gradually penetrated and partially replaced by newly grown bone tissue. During this process, the newly developing scaffold-bone compound needs to attain the stiffness of mandibular bone under normal physiological conditions. In this context, the question arises how the compound stiffness is driven by the key design parameters of the tissue engineering system: macroporosity, crack density, as well as scaffold resorption/bone formation rates. We here tackle this question by combining the latest state-of-the-art mathematical modeling techniques in the field of multiscale micromechanics, into an unprecedented suite of highly efficient, semi analytically defined computation steps resolving several levels of hierarchical organization, from the millimeter- down to the nanometer-scale. This includes several types of homogenization schemes, namely such for porous polycrystals with elongated solid elements, for cracked matrix-inclusion composites, as well as for assemblies of coated spherical compounds. Together with the experimentally known stiffnesses of hydroxyapatite crystals and mandibular bone tissue, the new mathematical model suggests that early stiffness recovery (i.e., within several weeks) requires total avoidance of microcracks in the hydroxyapatite scaffolds, while mid-term stiffness recovery (i.e., within several months) is additionally promoted by provision of small granule sizes, in combination with high bone formation and low scaffold resorption rates. PMID- 27708585 TI - Comparative Analysis of the Equivital EQ02 Lifemonitor with Holter Ambulatory ECG Device for Continuous Measurement of ECG, Heart Rate, and Heart Rate Variability: A Validation Study for Precision and Accuracy. AB - Background: The Equivital (EQ02) is a multi-parameter telemetric device offering both real-time and/or retrospective, synchronized monitoring of ECG, HR, and HRV, respiration, activity, and temperature. Unlike the Holter, which is the gold standard for continuous ECG measurement, EQO2 continuously monitors ECG via electrodes interwoven in the textile of a wearable belt. Objective: To compare EQ02 with the Holter for continuous home measurement of ECG, heart rate (HR), and heart rate variability (HRV). Methods: Eighteen healthy participants wore, simultaneously for 24 h, the Holter and EQ02 monitors. Per participant, averaged HR, and HRV per 5 min from the two devices were compared using Pearson correlation, paired T-test, and Bland-Altman analyses. Accuracy and precision metrics included mean absolute relative difference (MARD). Results: Artifact content of EQ02 data varied widely between (range 1.93-56.45%) and within (range 0.75-9.61%) participants. Comparing the EQ02 to the Holter, the Pearson correlations were respectively 0.724, 0.955, and 0.997 for datasets containing all data and data with < 50 or < 20% artifacts respectively. For datasets containing respectively all data, data with < 50, or < 20% artifacts, bias estimated by Bland-Altman analysis was -2.8, -1.0, and -0.8 beats per minute and 24 h MARD was 7.08, 3.01, and 1.5. After selecting a 3-h stretch of data containing 1.15% artifacts, Pearson correlation was 0.786 for HRV measured as standard deviation of NN intervals (SDNN). Conclusions: Although the EQ02 can accurately measure ECG and HRV, its accuracy and precision is highly dependent on artifact content. This is a limitation for clinical use in individual patients. However, the advantages of the EQ02 (ability to simultaneously monitor several physiologic parameters) may outweigh its disadvantages (higher artifact load) for research purposes and/ or for home monitoring in larger groups of study participants. Further studies can be aimed at minimizing the artifacts. PMID- 27708587 TI - In situ, Reversible Gating of a Mechanosensitive Ion Channel through Protein Lipid Interactions. AB - Understanding the functioning of ion channels, as well as utilizing their properties for biochemical applications requires control over channel activity. Herein we report a reversible control over the functioning of a mechanosensitive ion channel by interfering with its interaction with the lipid bilayer. The mechanosensitive channel of large conductance from Escherichia coli is reconstituted into liposomes and activated to its different sub-open states by titrating lysophosphatidylcholine (LPC) into the lipid bilayer. Activated channels are closed back by the removal of LPC out of the membrane by bovine serum albumin (BSA). Electron paramagnetic resonance spectra showed the LPC-dose dependent gradual opening of the channel pore in the form of incrementally increasing spin label mobility and decreasing spin-spin interaction. A method to reversibly open and close mechanosensitive channels to distinct sub-open conformations during their journey from the closed to the fully open state enables detailed structural studies to follow the conformational changes during channel functioning. The ability of BSA to revert the action of LPC opens new perspectives for the functional studies of other membrane proteins that are known to be activated by LPC. PMID- 27708586 TI - Modeling Ca2+-Bound Troponin in Excitation Contraction Coupling. AB - To explain disparate decay rates of cytosolic Ca2+ and structural changes in the thin filaments during a twitch, we model the time course of Ca2+-bound troponin (Tn) resulting from the free Ca2+ transient of fast skeletal muscle. In fibers stretched beyond overlap, the decay of Ca2+ as measured by a change in fluo-3 fluorescence is significantly slower than the intensity decay of the meridional 1/38.5 nm-1 reflection of Tn; this is not simply explained by considering only the Ca2+ binding properties of Tn alone (Matsuo et al., 2010). We apply a comprehensive model that includes the known Ca2+ binding properties of Tn in the context of the thin filament with and without cycling crossbridges. Calculations based on the model predict that the transient of Ca2+-bound Tn correlates with either the fluo-3 time course in muscle with overlapping thin and thick filaments or the intensity of the meridional 1/38.5 nm-1 reflection in overstretched muscle. Hence, cycling crossbridges delay the dissociation of Ca2+ from Tn. Correlation with the fluo-3 fluorescence change is not causal given that the transient of Ca2+-bound Tn depends on sarcomere length, whereas the fluo-3 fluorescence change does not. Transient positions of tropomyosin calculated from the time course of Ca2+-bound Tn are in reasonable agreement with the transient of measured perturbations of the Tn repeat in overlap and non-overlap muscle preparations. PMID- 27708588 TI - Application of Glycerol for Induced Powdery Mildew Resistance in Triticum aestivum L. AB - Previous work has demonstrated that glycerol-3-phosphate (G3P) and oleic acid (18:1) are two important signal molecules associated with plant resistance to fungi. In this article, we provide evidence that a 3% glycerol spray application 1-2 days before powdery mildew infection and subsequent applications once every 4 days was sufficient to stimulate the plant defense responses without causing any significant damage to wheat leaves. We found that G3P and oleic acid levels were markedly induced by powdery mildew infection. In addition, TaGLI1 (encoding a glycerol kinase) and TaSSI2 (encoding a stearoylacyl carrier protein fatty acid desaturase), two genes associated with the glycerol and fatty acid (FA) pathways, respectively, were induced by powdery mildew infection, and their promoter regions contain some fungal response elements. Moreover, exogenous application of glycerol increased the G3P level and decreased the level of oleic acid (18:1). Glycerol application induced the expression of pathogenesis-related (PR) genes (TaPR-1, TaPR-2, TaPR-3, TaPR-4, and TaPR-5), induced the generation of reactive oxygen species (ROS) before powdery mildew infection, and induced salicylic acid (SA) accumulation in wheat leaves. Further, we sprayed glycerol in a wheat field and found that it significantly (p < 0.05) reduced the severity of powdery mildew disease and lessened disease-associated kernel weight loss, all without causing any noticeable degradation in wheat seed quality. PMID- 27708589 TI - Synergistic Co-activation Increases the Extent of Mechanical Interaction between Rat Ankle Plantar-Flexors. AB - Force transmission between rat ankle plantar-flexors has been found for physiological muscle lengths and relative positions, but only with all muscles maximally activated. The aims of this study were to assess intermuscular mechanical interactions between ankle plantar-flexors during (i) fully passive conditions, (ii) excitation of soleus (SO), (iii) excitation of lateral gastrocnemius (LG), and (iv) during co-activation of SO, and LG (SO&LG). We assessed effects of proximal lengthening of LG and plantaris (PL) muscles (i.e., simulating knee extension) on forces exerted at the distal SO tendon (FSO) and on the force difference between the proximal and distal LG+PL tendons (DeltaFLG+PL) of the rat. LG+PL lengthening increased FSO to a larger extent (p = 0.017) during LG excitation (0.0026 N/mm) than during fully passive conditions (0.0009 N/mm). Changes in FSO in response to LG+PL lengthening were lower (p = 0.002) during SO only excitation (0.0056 N/mm) than during SO&LG excitation (0.0101 N/mm). LG+PL lengthening changed DeltaFLG+PL to a larger extent (p = 0.007) during SO excitation (0.0211 N/mm) than during fully passive conditions (0.0157 N/mm). In contrast, changes in DeltaFLG+PL in response to LG+PL lengthening during LG excitation (0.0331 N/mm) were similar (p = 0.161) to that during SO&LG excitation (0.0370 N/mm). In all conditions, changes of FSO were lower than those of DeltaFLG+PL. This indicates that muscle forces were transmitted not only between LG+PL and SO, but also between LG+PL and other surrounding structures. In addition, epimuscular myofascial force transmission between rat ankle plantar flexors was enhanced by muscle activation. However, the magnitude of this interaction was limited. PMID- 27708590 TI - QT Interval Derived Measurements in Patients with Cardiac Syndrome X Compared to Coronary Artery Disease. AB - Previous studies assessing effect of ischemia on ventricular repolarization are mostly directed toward patients with coronary artery disease (CAD); however, similar reports on cardiac syndrome X (CSX) are scarce. Whether microvascular dysfunction of CSX and ischemia induced by CAD produce comparable effect on ventricular repolarization is unclear and deserve further studies. In the present study, ECG measures of ventricular repolarization were compared between CAD and CSX patients (40 subjects in each group). Following evaluation of sociodemographic characteristics, medical and past medical history, a resting ECG was used to assess measurements of ventricular repolarization in each patient, namely, QT interval (QT), corrected QT interval (QTc), QT dispersion (QTd), corrected QT dispersion (QTcd), adjacent QT dispersion (AdQTd), QT dispersion ratio (QTdR), JT dispersion (JTd), and Corrected JT dispersion (JTcd). Results showed comparable QT intervals and QTd in CAD and CSX patients even after adjustment for the possible variations in gender, age and body mass index of the studied groups. Although JTd was increased in CSX subjects (26.6 +/- 7.2 ms) compared with CAD patients (22.7 +/- 6.5 ms, p = 0.019), statistical significance disappeared after correcting JT for variations in heart rate. QT and QTc were significantly below 440 ms in CAD as well as CSX patients (p < 0.001). In contrast, maximum QTd, maximum QTcd and AdQTd of CAD and CSX patients were significantly above 440 ms (p < 0.001). The means of JTd and JTcd were significantly above 22 ms and 24 ms respectively (p < 0.001, p = 0.001) in CSX but not CAD patients (p = 0.529, p = 0.281). The present findings clearly demonstrate comparable measures of ventricular repolarization in CAD and CSX patients and consequently an equal risk of cardiac events in both groups. PMID- 27708592 TI - Fuzzy Nonnative Phonolexical Representations Lead to Fuzzy Form-to-Meaning Mappings. AB - The present paper explores nonnative (L2) phonological encoding of lexical entries and dissociates the difficulties associated with L2 phonological and phonolexical encoding by focusing on similarly sounding L2 words that are not differentiated by difficult phonological contrasts. We test two main claims of the fuzzy lexicon hypothesis: (1) L2 fuzzy phonolexical representations are not fully specified and lack details at both phonological and phonolexical levels of representation (Experiment 1); and (2) fuzzy phonolexical representations can lead to establishing incorrect form-to-meaning mappings (Experiment 2). The Russian-English Translation Judgment Task (Experiment 1, TJT) explores how the degree of phonolexical similarity between a word and its lexical competitor affects lexical access of Russian words. Words with smaller phonolexical distance (e.g., parent-parrot) show longer reaction times and lower accuracy compared to words with a larger phonolexical distance (e.g., parent-parchment) in lower proficiency nonnative speakers, and, to a lesser degree, higher-proficiency speakers. This points to a lack of detail in nonnative phonolexical representations necessary for efficient lexical access. The Russian Pseudo Semantic Priming task (Experiment 2, PSP) addresses the vulnerability of form-to meaning mappings as a consequence of fuzzy phonolexical representations in L2. We primed the target with a word semantically related to its phonological competitor, or a potentially confusable word. The findings of Experiment 2 extend the results of Experiment 1 that, unlike native speakers, nonnative speakers do not properly encode phonolexical information. As a result, they are prone to access an incorrect lexical representation of a competitor word, as indicated by a slowdown in the judgments to confusable words. The study provides evidence that fuzzy phonolexical representations result in unfaithful form-to-meaning mappings, which lead to retrieval of incorrect semantic content. The results of the study are in line with existing research in support of less detailed L2 phonolexical representations, and extend the findings to show that the fuzziness of phonolexical representations can arise even when confusable words are not differentiated by difficult phonological contrasts. PMID- 27708593 TI - Sexual Aggression Victimization and Perpetration among Male and Female College Students in Chile. AB - Evidence on the prevalence of sexual aggression among college students is primarily based on studies from Western countries. In Chile, a South American country strongly influenced by the Catholic Church, little research on sexual aggression among college students is available. Therefore, the purpose of the present study was to examine the prevalence of sexual aggression victimization and perpetration since the age of 14 (the legal age of consent) in a sample of male and female students aged between 18 and 29 years from five Chilean universities (N = 1135), to consider possible gender differences, and to study the extent to which alcohol was involved in the reported incidents of perpetration and victimization. Sexual aggression victimization and perpetration was measured with a Chilean Spanish version of the Sexual Aggression and Victimization Scale (SAV-S), which includes three coercive strategies (use or threat of physical force, exploitation of an incapacitated state, and verbal pressure), three victim-perpetrator constellations (current or former partners, friends/acquaintances, and strangers), and four sexual acts (sexual touch, attempted sexual intercourse, completed sexual intercourse, and other sexual acts, such as oral sex). Overall, 51.9% of women and 48.0% of men reported at least one incident of sexual victimization, and 26.8% of men and 16.5% of women reported at least one incident of sexual aggression perpetration since the age of 14. For victimization, only few gender differences were found, but significantly more men than women reported sexual aggression perpetration. A large proportion of perpetrators also reported victimization experiences. Regarding victim perpetrator relationship, sexual aggression victimization and perpetration were more common between persons who knew each other than between strangers. Alcohol use by the perpetrator, victim, or both was involved in many incidents of sexual aggression victimization and perpetration, particularly among strangers. The present data are the first to provide a systematic and detailed picture of sexual aggression among college students in Chile, including victimization and perpetration reports by both men and women and confirming the critical role of alcohol established in past research from Western countries. PMID- 27708594 TI - Cross-Lagged Relationships between Morphological Awareness and Reading Comprehension among Chinese Children. AB - The present study examined the developmental relationship between morphological awareness (MA) and reading comprehension (RC) using a 2-year and four-wave cross lagged design with a sample of 149 Chinese children (80 males and 69 females). We measured children's MA, word reading (WR), and RC from T1 to T4, in addition to phonological awareness, vocabulary knowledge, and general cognitive ability at T1 as control measures. Four plausible cross-lagged models were assessed and compared to examine the direction of the developmental relationships between MA and RC over time. Results found support for a reciprocal-causation model, that is, MA stably predicted subsequent RC, and the reverse relation was also found. Longitudinal mediation analyses revealed that WR partially mediated the relationship between MA and RC in Chinese children. These findings extend our understanding of the relationship between MA and RC. The practical implications for these two developing skills in Chinese children are discussed. PMID- 27708595 TI - Limited Near and Far Transfer Effects of Jungle Memory Working Memory Training on Learning Mathematics in Children with Attentional and Mathematical Difficulties. AB - The goal of this randomized controlled trial was to investigate whether Jungle Memory working memory training (JM) affects performance on working memory tasks, performance in mathematics and gains made on a mathematics training (MT) in school aged children between 9-12 years old (N = 64) with both difficulties in mathematics, as well as attention and working memory. Children were randomly assigned to three groups and were trained in two periods: (1) JM first, followed by MT, (2) MT first, followed by JM, and (3) a control group that received MT only. Bayesian analyses showed possible short term effects of JM on near transfer measures of verbal working memory, but none on visual working memory. Furthermore, support was found for the hypothesis that children that received JM first, performed better after MT than children who did not follow JM first or did not train with JM at all. However, these effects could be explained at least partly by frequency of training effects, possibly due to motivational issues, and training-specific factors. Furthermore, it remains unclear whether the effects found on improving mathematics were actually mediated by gains in working memory. It is argued that JM might not train the components of working memory involved in mathematics sufficiently. Another possible explanation can be found in the training's lack of adaptivity, therefore failing to provide the children with tailored instruction and feedback. Finally, it was hypothesized that, since effect sizes are generally small, training effects are bound to a critical period in development. PMID- 27708596 TI - The Transfer of Object Learning after Training with Multiple Exemplars. AB - Object recognition improves with training. This training effect only partially generalizes to untrained images of the trained objects (new exemplars, orientation,...). The aim of this study is to investigate whether and to what extent the learning transfer improves when participants are trained with more exemplars of an object. Participants were trained to recognize two sets of stimuli using a backward masking paradigm. During training with the first set, only one exemplar of each object was presented. The second set was trained using four exemplars of each object. After 3 days of training, participants were tested on all the trained exemplars and a completely new exemplar of the same objects. In addition, recognition performance was compared to a set of completely new objects. For the objects of which four exemplars were used during training, participants showed more generalization toward new exemplars compared to when they were only trained with one exemplar. Part of the generalization effect extended to completely new objects. In conclusion, more variation during training leads to more generalization toward new visual stimuli. PMID- 27708597 TI - Methodological Considerations about the Use of Bimodal Oddball P300 in Psychiatry: Topography and Reference Effect. AB - Event-related potentials (ERPs) bimodal oddball task has disclosed increased sensitivity to show P300 modulations to subclinical symptoms. Even if the utility of such a procedure has still to be confirmed at a clinical level, gathering normative values of this new oddball variant may be of the greatest interest. We specifically addressed the challenge of defining the best location for the recording of P3a and P3b components and selecting the best reference to use by investigating the effect of an offline re-reference procedure on recorded bimodal P3a and P3b. Forty young and healthy subjects were submitted to a bimodal (synchronized and always congruent visual and auditory stimuli) three-stimulus oddball task in which 140 frequent bimodal stimuli, 30 deviant "target" stimuli and 30 distractors were presented. Task consisted in clicking as soon as possible on the targets, and not paying attention to frequent stimuli and distractors. This procedure allowed us to record, for each individual, the P3a component, referring to the novelty process related to distractors processing, and the P3b component, linked to the processing of the target stimuli. Results showed that both P3a and P3b showed maximal amplitude in Pz. However, P3a displayed a more central distribution. Nose reference was also shown to give maximal amplitudes compared with average and linked mastoids references. These data were discussed in light of the necessity to develop multi-site recording guidelines to furnish sets of ERPs data comparable across laboratories.

PMID- 27708598 TI - Crave, Like, Eat: Determinants of Food Intake in a Sample of Children and Adolescents with a Wide Range in Body Mass. AB - Obesity is a heterogeneous condition with obese individuals displaying different eating patterns. Growing evidence suggests that there is a subgroup of obese adults that is marked by frequent and intense food cravings and addiction-like consumption of high-calorie foods. Little is known, however, about such a subgroup of obese individuals in childhood and adolescence. In the present study, a sample of children and adolescents with a wide range in body mass was investigated and trait food craving, liking for and intake of high- and low calorie foods was measured. One-hundred and forty-two children and adolescents (51.4% female, n = 73; Mage = 13.7 years, SD = 2.25; MBMI-SDS = 1.26, SD = 1.50) completed the Food Cravings Questionnaire-Trait, then viewed pictures of high- and low-calorie foods and rated their liking for them, and subsequently consumed some of these foods in a bogus taste test. Contrary to expectations, higher body mass was associated with lower consumption of high-calorie foods. However, there was an interaction between body mass and trait food craving when predicting food consumption: in obese participants, higher trait food craving was associated with higher consumption of high-calorie foods and this association was not found in normal-weight participants. The relationship between trait food craving and high calorie food consumption within obese individuals was mediated by higher liking for high-calorie foods (but not by liking for low-calorie foods). Thus, similar to adults, a subgroup of obese children and adolescents - characterized by high trait food craving - seems to exist, calling for specific targeted treatment strategies. PMID- 27708600 TI - Attention Deficit/Hyperactivity Disorder (ADHD) Diagnosis: An Activation Executive Model. AB - Attention deficit with, or without, hyperactivity and impulsivity (ADHD) is categorized as neuro-developmental disorder. ADHD is a common disorder in childhood and one of the most frequent conditions affecting school ages. This disorder is characterized by a persistent behavioral pattern associated with inattention, over-activity (or hyperactivity), and difficulty in controlling impulses. Current research suggests the existence of certain patterns of cortical activation and executive control, which could more objectively identify ADHD. Through the use of a risk and resilience model, this research aimed to analyze the interaction between brain activation variables (nirHEG and Q-EEG) and executive variables (Continuous performance test -CPT-) in subjects with ADHD. The study involved 499 children, 175 females (35.1%) and 324 males (64.91%); aged from 6 to 16 years (M = 11.22, SD = 1.43). Two hundred and fifty six of the children had been diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) and 243 were without ADHD. For the analysis of this objective, a causal model was designed to include the following different measures of task-execution: CPT TOVA (omissions, commissions, response time, variability, D prime and the ADHD Index); electrical activity (using Q-EEG); and blood-flow oxygenation activity (using nirHEG). The causal model was tested by means of structural equation modeling (SEM). The model that had been constructed was based upon three general assumptions: (1) There are different causal models for children with ADHD and those without ADHD; (2) The activation measures influence students' executive performance; and (3) There are measurable structural differences between the ADHD and control group models (executive and activation). In general, the results showed that: (a) activation measures influence executive patterns differently, (b) the relationship between activation variables (nirHEG and Q-EEG) depends on the brain zone being studied, (c) both groups showed important differences in variables correlation, with a good fit in each model (with and without ADHD). Lastly, the results were analyzed with a view to the diagnosis procedure. Therefore, we discuss the implications for future research. PMID- 27708601 TI - Gratitude and Adolescents' Subjective Well-Being in School: The Multiple Mediating Roles of Basic Psychological Needs Satisfaction at School. AB - Based on the relation between gratitude and general subjective well-being (SWB), and Basic Psychological Needs Theory (Ryan and Deci, 2000), the present study's aim was to use structural equation modeling to test the multiple mediational roles of the satisfaction of three basic psychological needs at school in accounting for the association between gratitude and SWB in school (school satisfaction, school affect) in adolescents. A total of 881 Chinese adolescents (427 males; Mean age = 12.97) completed a multi-measure questionnaire that tapped the targeted variables. Findings revealed that gratitude related significantly, positively to adolescents' SWB in school. Moreover, a multiple-mediators analysis suggested that relatedness and competence needs satisfaction at school mediated the relation between gratitude and SWB in school. Lastly, a multiple-mediators analysis also indicated that autonomy needs satisfaction mediated the relation between relatedness and competence needs and SWB in school. Limitations and practical applications of the study were discussed. PMID- 27708602 TI - The Bidirectional Effect between Momentary Affective States and Exercise Duration on a Day Level. AB - Despite the well-documented positive effect of exercise on health outcomes, most people do not succeed in exercising regularly. In addition to several other influences, affective states seem to support exercise participation. Associations between exercise and affect have been shown in the laboratory. However, the dynamic relation between affect and exercise in daily life is not yet well understood. The objective of this study was to investigate the bi-directional effect of momentary affective states on naturally occurring exercise and vice versa in healthy participants in real-life environments by applying an ecological momentary assessment design. We hypothesized that (1) exercise duration is positively associated with affective states on a day level, (2) affective states in the morning predict subsequent exercise duration, and (3) exercise duration predicts affective states in the evening on that respective day. Data from N = 60 students aged between 19 and 32 years were analyzed. Affect and exercise duration were assessed daily over a period of 20 days via an electronic diary. Multilevel analysis revealed that positive affective valence was positively associated with exercise duration (p = 0.003) on a day level. In addition, the more the participants exercised that respective day, the better and more content they felt in the evening (p = 0.009). Energetic arousal in the morning significantly predicted subsequent exercise duration (p = 0.045). The findings indicate that it would be worthwhile to focus more on within-subject analyses when analyzing the dynamic relation between affect and exercise. Furthermore, affective states should be taken into account in creating effective interventions to foster exercise behavior and enhance maintenance. PMID- 27708603 TI - Engaging in Rather than Disengaging from Stress: Effective Coping and Perceived Control. AB - Being able to cope effectively with stress can help people to avoid negative consequences for their psychological well-being. The purpose of this study was to find out why some coping strategies are effective in reducing the negative effect of stressors on well-being and some are not. We argue that the degree to which such coping strategies engage or disengage people from stressful incidents is related to their perceived control of the situation that, in turn, is positively associated with their psychological well-being. We thus propose that the relationship between coping and psychological well-being is mediated by the extent of perceived sense of control. We collected cross-sectional data from a large heterogeneous sample (N = 543) in the Netherlands. We assessed seven different coping strategies, perceived control, and psychological well-being. Our results indeed revealed that strategies reflecting more engaged coping such as active confronting and reassuring thoughts, were associated with more sense of control and therefore to psychological well-being. In contrast, strategies reflecting disengagement coping, such as passive reaction pattern, palliative reaction, and avoidance, were associated with less perceived control, which in turn was negatively associated with psychological well-being. Results regarding the coping strategies expressing emotions and seeking social support were less straightforward, with the former being negatively associated with perceived control and psychological well-being, even though this strategy has stress engaging elements, and the latter only showing a positive indirect effect on psychological well-being via perceived control, but no positive main effect on well-being. These findings are discussed from the perspective of stress being an environment-perception-response process.

PMID- 27708591 TI - Cognitive Dysfunction, Affective States, and Vulnerability to Nicotine Addiction: A Multifactorial Perspective. AB - Although smoking prevalence has declined in recent years, certain subpopulations continue to smoke at disproportionately high rates and show resistance to cessation treatments. Individuals showing cognitive and affective impairments, including emotional distress and deficits in attention, memory, and inhibitory control, particularly in the context of psychiatric conditions, such as attention deficit hyperactivity disorder, schizophrenia, and mood disorders, are at higher risk for tobacco addiction. Nicotine has been shown to improve cognitive and emotional processing in some conditions, including during tobacco abstinence. Self-medication of cognitive deficits or negative affect has been proposed to underlie high rates of tobacco smoking among people with psychiatric disorders. However, pre-existing cognitive and mood disorders may also influence the development and maintenance of nicotine dependence, by biasing nicotine-induced alterations in information processing and associative learning, decision-making, and inhibitory control. Here, we discuss the potential forms of contribution of cognitive and affective deficits to nicotine addiction-related processes, by reviewing major clinical and preclinical studies investigating either the procognitive and therapeutic action of nicotine or the putative primary role of cognitive and emotional impairments in addiction-like features. PMID- 27708608 TI - Multimodal Integration of Spatial Information: The Influence of Object-Related Factors and Self-Reported Strategies. AB - Spatial representations are a result of multisensory information integration. More recent findings suggest that the multisensory information processing of a scene can be facilitated when paired with a semantically congruent auditory signal. This congruency effect was taken as evidence that audio-visual integration occurs for complex scenes. As navigation in our environment consists of a seamless integration of complex sceneries, a fundamental question arises: how is human landmark-based wayfinding affected by multimodality? In order to address this question, two experiments were conducted in a virtual environment. The first experiment compared wayfinding and landmark recognition performance in unimodal visual and acoustic landmarks. The second experiment focused on the congruency of multimodal landmark combinations and additionally assessed subject's self-reported strategies (i.e., whether they focused on direction sequences or landmarks). We demonstrate (1) the equality of acoustic and visual landmarks and (2) the congruency effect for the recognition of landmarks. Additionally, the results point out that self-reported strategies play a role and are an under-investigated topic in human landmark-based wayfinding. PMID- 27708607 TI - Editorial: Research Methods Pedagogy: Engaging Psychology Students in Research Methods and Statistics. PMID- 27708605 TI - Infants Encode Phonetic Detail during Cross-Situational Word Learning. AB - Infants often hear new words in the context of more than one candidate referent. In cross-situational word learning (XSWL), word-object mappings are determined by tracking co-occurrences of words and candidate referents across multiple learning events. Research demonstrates that infants can learn words in XSWL paradigms, suggesting that it is a viable model of real-world word learning. However, these studies have all presented infants with words that have no or minimal phonological overlap (e.g., BLICKET and GAX). Words often contain some degree of phonological overlap, and it is unknown whether infants can simultaneously encode fine phonological detail while learning words via XSWL. We tested 12-, 15-, 17-, and 20-month-olds' XSWL of eight words that, when paired, formed non-minimal pairs (MPs; e.g., BON-DEET) or MPs (e.g., BON-TON, DEET-DIT). The results demonstrated that infants are able to learn word-object mappings and encode them with sufficient phonetic detail as to identify words in both non-minimal and MP contexts. Thus, this work suggests that infants are able to simultaneously discriminate phonetic differences between words and map words to referents in an implicit learning paradigm such as XSWL.

AB - Individual players act as a coherent unit during team sports performance, forming a team synergy. A synergy is a collective property of a task-specific organization of individuals, such that the degrees of freedom of each individual in the system are coupled, enabling the degrees of freedom of different individuals to co-regulate each other. Here, we present an explanation for the emergence of such collective behaviors, indicating how these can be assessed and understood through the measurement of key system properties that exist, considering the contribution of each individual and beyond These include: to (i) dimensional compression, a process resulting in independent degree of freedom being coupled so that the synergy has fewer degrees of freedom than the set of components from which it arises; (ii) reciprocal compensation, if one element do not produce its function, other elements should display changes in their contributions so that task goals are still attained; (iii) interpersonal linkages, the specific contribution of each element to a group task; and (iv), degeneracy, structurally different components performing a similar, but not necessarily identical, function with respect to context. A primary goal of our analysis is to highlight the principles and tools required to understand coherent and dynamic team behaviors, as well as the performance conditions that make such team synergies possible, through perceptual attunement to shared affordances in individual performers. A key conclusion is that teams can be trained to perceive how to use and share specific affordances, explaining how individual's behaviors self-organize into a group synergy. Ecological dynamics explanations of team behaviors can transit beyond mere ratification of sport performance, providing a comprehensive conceptual framework to guide the implementation of diagnostic measures by sport scientists, sport psychologists and performance analysts. Complex adaptive systems, synergies, group behaviors, team sport performance, ecological dynamics, performance analysis. PMID- 27708610 TI - Patterns of Co-Occurring Gray Matter Concentration Loss across the Huntington Disease Prodrome. AB - Huntington disease (HD) is caused by an abnormally expanded cytosine-adenine guanine (CAG) trinucleotide repeat in the HTT gene. Age and CAG-expansion number are related to age at diagnosis and can be used to index disease progression. However, observed onset-age variability suggests that other factors also modulate progression. Indexing prodromal (pre-diagnosis) progression may highlight therapeutic targets by isolating the earliest-affected factors. We present the largest prodromal HD application of the univariate method voxel-based morphometry (VBM) and the first application of the multivariate method source-based morphometry (SBM) to, respectively, compare gray matter concentration (GMC) and capture co-occurring GMC patterns in control and prodromal participants. Using structural MRI data from 1050 (831 prodromal, 219 control) participants, we characterize control-prodromal, whole-brain GMC differences at various prodromal stages. Our results provide evidence for (1) regional co-occurrence and differential patterns of decline across the prodrome, with parietal and occipital differences commonly co-occurring, and frontal and temporal differences being relatively independent from one another, (2) fronto-striatal circuits being among the earliest and most consistently affected in the prodrome, (3) delayed degradation in some movement-related regions, with increasing subcortical and occipital differences with later progression, (4) an overall superior-to-inferior gradient of GMC reduction in frontal, parietal, and temporal lobes, and (5) the appropriateness of SBM for studying the prodromal HD population and its enhanced sensitivity to early prodromal and regionally concurrent differences. PMID- 27708611 TI - A History of Mild Traumatic Brain Injury Affects Peripheral Pulse Oximetry during Normobaric Hypoxia. AB - INTRODUCTION: Physiological and emotional stressors increase symptoms of concussion in recently injured individuals and both forms of stress-induced symptoms in people recovering from mild traumatic brain injury (mTBI), but who are asymptomatic when not stressed or are at rest. METHODS: Healthy asymptomatic adults (25.0 +/- 5.1 years) with a history of mTBI (n = 36) and matched healthy controls (HC) (n = 36) with no mTBI history were exposed to three levels of normobaric hypoxic stress generated with the Reduced Oxygen Breathing Device (ROBD) (Environics, Inc., Tollande, CT, USA), which reduced the percent O2 by mixing sea level air with nitrogen. The ROBD reduced the percent O2 in the breathable air from the normal 21% to 15.5% O2, 14% O2, and 13% O2. Under these conditions: (a) a standard pulse oximeter recorded peripheral oxygen saturation (SpO2) and pulse rate (beats per minute) and (b) the Functional Impairment Tester (FIT) (PMI, Inc., Rockville, MD, USA) recorded saccadic velocity and pupillary response dynamics to a brief light flash. RESULTS: For all three hypoxic stress conditions, the mTBI group had significantly higher SpO2 during the final minute of exposure than did the controls [F(2.17,151.8) = 5.29, p < 0.001, eta2 = 0.852] and the rate of SpO2 change over time was significantly shallower for the mTBI than for the controls [F(2.3,161.3) = 2.863, p < 0.001, eta2 = 0.569], Greenhouse Geisser corrected. Overall, mTBI had lower pulse rate but the difference was only significant for the 14% O2 condition. FIT oculomotor measures were not sensitive to group differences. When exposed to mild or moderate normobaric hypoxic stress (15% O2): (1) SpO2 differences emerged between the mTBI and matched HC groups, (2) heart rate trended lower in the mTBI group, and (3) FIT measures were not sensitive to group differences. CONCLUSION: A relatively minor hypoxic challenge can reveal measurable differences in SpO2 and heart rate in otherwise asymptomatic individuals with a history of mTBI. PMID- 27708613 TI - The Impact of MS-Related Cognitive Fatigue on Future Brain Parenchymal Loss and Relapse: A 17-Month Follow-up Study. AB - BACKGROUND: Fatigue is a disabling syndrome in multiple sclerosis (MS), which may be associated with inflammation and faster disease progression. OBJECTIVE: To analyze the significance of cognitive fatigue for subsequent disease progression. METHOD: We followed 46 MS patients and 14 healthy controls in a study over 17 months. At the beginning (t1) and at the end (t2) of the study participants scored their fatigue, performed the Multiple Sclerosis Functional Composite and received MRI scanning, encompassing MPR T1, FLAIR, and DTI sequences. At t1, MS patients were divided into those with and those without cognitive fatigue (cut off score for moderate cognitive fatigue of the Fatigue Scale for Motor and Cognition). We calculated ANCOVAs for repeated measurement to analyze the relevance of cognitive fatigue status for the number of relapses and for MRI parameters. RESULTS: At t1, but not at t2, patients with cognitive fatigue showed increased axial and radial diffusivity of corpus callosum fibers. At t2, these patients showed significantly more loss of brain parenchyma and greater enlargement of lateral ventricles. Moreover, they developed more relapses, but there was no difference in lesion load or in performance deterioration. Additional analyses showed that only cognitive fatigue but not a more general score for fatigue (Fatigue Severity Scale) had an impact on the worsening of the disease status. CONCLUSION: Patients with cognitive fatigue may develop more brain atrophy and relapses during the next 17 months than patients without cognitive fatigue. Hence, experiencing cognitive fatigue might indicate more aggressive inflammatory processes and subsequent neurodegeneration. PMID- 27708612 TI - Counteracting Fatigue in Multiple Sclerosis with Right Parietal Anodal Transcranial Direct Current Stimulation. AB - BACKGROUND: Fatigue in multiple sclerosis (MS) patients appears to correlate with vigilance decrement as reflected in an increase in reaction time (RT) and errors with prolonged time-on-task. OBJECTIVES: The aim of this study was to investigate whether anodal transcranial direct current stimulation (tDCS) over the right parietal or frontal cortex counteracts fatigue-associated vigilance decrement and subjective fatigue. METHODS: In study I, a randomized double-blind placebo controlled study, anodal tDCS (1.5 mA) was delivered to the right parietal cortex or the right frontal cortex of 52 healthy participants during the first 20 min of a 40-min lasting visual vigilance task. Study II, also a randomized double-blind placebo-controlled study, investigated the effect of anodal tDCS (1.5 mA) over the right parietal cortex in 46 MS patients experiencing cognitive fatigue. tDCS was delivered for 20 min before patients performed a 20-min lasting visual vigilance task. RESULTS: Study I showed that right parietal stimulation, but not right frontal stimulation, counteracts the increase in RT associated with vigilance decrement. Hence, only right parietal stimulation was applied to the MS patients in study II. Stimulation had a significant effect on vigilance decrement in mildly to moderately cognitively fatigued MS patients. Vigilance testing significantly increased the feeling of fatigue independent of stimulation. CONCLUSION: Anodal tDCS over the right parietal cortex can counteract the increase in RTs during vigilance performance, but not the increase in subjective fatigue. This finding is compatible with our model of fatigue in MS, suggesting a dissociation between the feeling and the behavioral characteristics of fatigue. PMID- 27708614 TI - Diving Response in Rats: Role of the Subthalamic Vasodilator Area. AB - Diving response (DR) is a powerful integrative response targeted toward survival of the hypoxic/anoxic conditions. Being present in all animals and humans, it allows to survive adverse conditions like diving. Earlier, we discovered that forehead stimulation affords neuroprotective effect, decreasing infarction volume triggered by permanent occlusion of the middle cerebral artery in rats. We hypothesized that cold stimulation of the forehead induces DR in rats, which, in turn, exerts neuroprotection. We compared autonomic [AP, heart rate (HR), cerebral blood flow (CBF)] and EEG responses to the known DR-triggering stimulus, ammonia stimulation of the nasal mucosa, cold stimulation of the forehead, and cold stimulation of the glabrous skin of the tail base in anesthetized rats. Responses in AP, HR, CBF, and EEG to cold stimulation of the forehead and ammonia vapors instillation into the nasal cavity were comparable and differed significantly from responses to the cold stimulation of the tail base. Excitotoxic lesion of the subthalamic vasodilator area (SVA), which is known to participate in CBF regulation and to afford neuroprotection upon excitation, failed to affect autonomic components of the DR evoked by forehead cold stimulation or nasal mucosa ammonia stimulation. We conclude that cold stimulation of the forehead triggers physiological response comparable to the response evoked by ammonia vapor instillation into nasal cavity, which is considered as stimulus triggering protective DR. These observations may explain the neuroprotective effect of the forehead stimulation. Data demonstrate that SVA does not directly participate in the autonomic adjustments accompanying DR; however, it is involved in diving-evoked modulation of EEG. We suggest that forehead stimulation can be employed as a stimulus capable of triggering oxygen conserving DR and can be used for neuroprotective therapy. PMID- 27708615 TI - Reduced Venous Compliance in Young Women with Type 1 Diabetes - Further Aggravated by Prolonged Elevated Levels of HbA1c. AB - BACKGROUND: Young patients with diabetes present with reduced compensatory responses to hypovolemic stress. Less compliant veins could be a contributing factor, since roughly two-thirds of the blood volume resides in the venous system as a blood reservoir, adjusting proper venous inflow to the heart. The aim of this study was to measure venous compliance and lower limb blood pooling during hypovolemic stress, and to correlate them to indices of diabetes severity and glucose control. METHODS: Fifteen young women with type 1 diabetes (DW) and 18 healthy age-matched women (C) were subjected to lower body negative pressure (LBNP) (11-44 mmHg), creating hypovolemic stress. Lower limb blood pooling was measured with strain gage technique and venous compliance calculated as the relationship between ?V/?P. RESULTS: DW presented with reduced blood pooling (e.g., blood pooling during LBNP of 44 mmHg, DW, 1.69 +/- 0.10; C, 2.10 +/- 0.08 (ml/100 ml), and P = 0.003). Calculated venous compliance was also reduced in DW (e.g., compliance at 20 mmHg, DW, 0.046 +/- 0.003; C, 0.059 +/- 0.002 (ml/100 ml/mmHg), and P = 0.002). A progressive reduction in both venous compliance (P < 0.007) and blood pooling (P < 0.005) was seen with increasing level of HbA1c, and furthermore, less strongly associated with presence of microvascular disease (signs of retinopathy). CONCLUSION: Women with type 1 diabetes present with both reduced venous compliance and blood pooling. The reductions were particularly present in patients with long-standing poor glycemic control. PMID- 27708617 TI - Increased Circulating Adiponectin in Response to Thiazolidinediones: Investigating the Role of Bone Marrow Adipose Tissue. AB - BACKGROUND: Bone marrow adipose tissue (MAT) contributes to increased circulating adiponectin, an insulin-sensitizing hormone, during caloric restriction (CR), but whether this occurs in other contexts remains unknown. The antidiabetic thiazolidinediones (TZDs) also promote MAT expansion and hyperadiponectinemia, even without increasing adiponectin expression in white adipose tissue (WAT). OBJECTIVES: To test the hypothesis that MAT expansion contributes to TZD associated hyperadiponectinemia, we investigated the effects of rosiglitazone, a prototypical TZD, in wild-type (WT) or Ocn-Wnt10b mice. The latter resist MAT expansion during CR, leading us to postulate that they would also resist this effect of rosiglitazone. DESIGN: Male and female WT or Ocn-Wnt10b mice (C57BL/6J) were treated with or without rosiglitazone for 2, 4, or 8 weeks, up to 30 weeks of age. MAT content was assessed by osmium tetroxide staining and adipocyte marker expression. Circulating adiponectin was determined by ELISA. RESULTS: In WT mice, rosiglitazone caused hyperadiponectinemia and MAT expansion. Compared to WT mice, Ocn-Wnt10b mice had significantly less MAT in distal tibiae and sometimes in proximal tibiae; however, interpretation was complicated by the leakage of osmium tetroxide from ruptures in some tibiae, highlighting an important technical consideration for osmium-based MAT analysis. Despite decreased MAT in Ocn-Wnt10b mice, circulating adiponectin was generally similar between WT and Ocn-Wnt10b mice; however, in females receiving rosiglitazone for 4 weeks, hyperadiponectinemia was significantly blunted in Ocn-Wnt10b compared to WT mice. Notably, this was also the only group in which tibial adiponectin expression was lower than in WT mice, suggesting a close association between MAT adiponectin production and circulating adiponectin. However, rosiglitazone significantly increased adiponectin protein expression in WAT, suggesting that WAT contributes to hyperadiponectinemia in this context. Finally, rosiglitazone upregulated uncoupling protein 1 in brown adipose tissue (BAT), but this protein was undetectable in tibiae, suggesting that MAT is unlikely to share thermogenic properties of BAT. CONCLUSION: TZD-induced hyperadiponectinemia is closely associated with increased adiponectin production in MAT but is not prevented by the partial loss of MAT that occurs in Ocn-Wnt10b mice. Thus, more robust loss-of MAT models are required for future studies to better establish MAT's elusive functions, both on an endocrine level and beyond. PMID- 27708618 TI - The Underexploited Role of Non-Coding RNAs in Lysosomal Storage Diseases. AB - Non-coding RNAs (ncRNAs) are a functional class of RNA involved in the regulation of several cellular processes which may modulate disease onset, progression, and prognosis. Lysosomal storage diseases (LSD) are a group of rare disorders caused by mutations of genes encoding specific hydrolases or non-enzymatic proteins, characterized by a wide spectrum of manifestations. The alteration of ncRNA levels is well established in several human diseases such as cancer and auto immune disorders; however, there is a lack of information focused on the role of ncRNA in rare diseases. Recent reports related to changes in ncRNA expression and its consequences on LSD physiopathology show us the importance to keep advancing in this field. This article will summarize recent findings and provide key points for further studies on LSD and ncRNA association. PMID- 27708616 TI - The Bone Marrow-Derived Stromal Cells: Commitment and Regulation of Adipogenesis. AB - Bone marrow (BM) microenvironment represents an important compartment of bone that regulates bone homeostasis and the balance between bone formation and bone resorption depending on the physiological needs of the organism. Abnormalities of BM microenvironmental dynamics can lead to metabolic bone diseases. BM stromal cells (also known as skeletal or mesenchymal stem cells) [bone marrow stromal stem cell (BMSC)] are multipotent stem cells located within BM stroma and give rise to osteoblasts and adipocytes. However, cellular and molecular mechanisms of BMSC lineage commitment to adipocytic lineage and regulation of BM adipocyte formation are not fully understood. In this review, we will discuss recent findings pertaining to identification and characterization of adipocyte progenitor cells in BM and the regulation of differentiation into mature adipocytes. We have also emphasized the clinical relevance of these findings. PMID- 27708619 TI - Epidemiological and Genomic Landscape of Azole Resistance Mechanisms in Aspergillus Fungi. AB - Invasive aspergillosis is a life-threatening mycosis caused by the pathogenic fungus Aspergillus. The predominant causal species is Aspergillus fumigatus, and azole drugs are the treatment of choice. Azole drugs approved for clinical use include itraconazole, voriconazole, posaconazole, and the recently added isavuconazole. However, epidemiological research has indicated that the prevalence of azole-resistant A. fumigatus isolates has increased significantly over the last decade. What is worse is that azole-resistant strains are likely to have emerged not only in response to long-term drug treatment but also because of exposure to azole fungicides in the environment. Resistance mechanisms include amino acid substitutions in the target Cyp51A protein, tandem repeat sequence insertions at the cyp51A promoter, and overexpression of the ABC transporter Cdr1B. Environmental azole-resistant strains harboring the association of a tandem repeat sequence and punctual mutation of the Cyp51A gene (TR34/L98H and TR46/Y121F/T289A) have become widely disseminated across the world within a short time period. The epidemiological data also suggests that the number of Aspergillus spp. other than A. fumigatus isolated has risen. Some non-fumigatus species intrinsically show low susceptibility to azole drugs, imposing the need for accurate identification, and drug susceptibility testing in most clinical cases. Currently, our knowledge of azole resistance mechanisms in non-fumigatus Aspergillus species such as A. flavus, A. niger, A. tubingensis, A. terreus, A. fischeri, A. lentulus, A. udagawae, and A. calidoustus is limited. In this review, we present recent advances in our understanding of azole resistance mechanisms particularly in A. fumigatus. We then provide an overview of the genome sequences of non-fumigatus species, focusing on the proteins related to azole resistance mechanisms. PMID- 27708620 TI - Beneficial Effects of Spices in Food Preservation and Safety. AB - Spices have been used since ancient times. Although they have been employed mainly as flavoring and coloring agents, their role in food safety and preservation have also been studied in vitro and in vivo. Spices have exhibited numerous health benefits in preventing and treating a wide variety of diseases such as cancer, aging, metabolic, neurological, cardiovascular, and inflammatory diseases. The present review aims to provide a comprehensive summary of the most relevant and recent findings on spices and their active compounds in terms of targets and mode of action; in particular, their potential use in food preservation and enhancement of shelf life as a natural bioingredient. PMID- 27708621 TI - Reassessment of the Enteropathogenicity of Mesophilic Aeromonas Species. AB - Cases of Aeromonas diarrhea have been described all over the world. The genus Aeromonas includes ca. 30 species, of which 10 have been isolated in association with gastroenteritis. The dominating species that account for ca. 96% of the identified strains are Aeromonas caviae, A. veronii, A. dhakensis, and A. hydrophila. However, the role of Aeromonas as a true enteropathogen has been questioned on the basis of the lack of outbreaks, the non-fulfillment of Koch's postulates and the low numbers of acute illnesses in the only existing human challenge study. In the present study we reassess the enteropathogenicity of Aeromonas using dose response models for microbial infection and acute illness. The analysis uses the data from the human challenge study and additional data from selected outbreak investigations where the numbers exposed and the dose were reported, allowing their inclusion as "natural experiments". In the challenge study several cases of asymptomatic shedding were found (26.3%, 15/57), however, only 3.5% (2/57) of those challenged with Aeromonas developed acute enteric symptoms (i.e., diarrhea). The "natural experiments" showed a much higher risk of illness associated with exposure to Aeromonas, even at moderate to low doses. The median dose required for 1% illness risk, was ~1.4 * 104 times higher in the challenge study (1.24 * 104 cfu) compared to natural exposure events (0.9 cfu). The dose response assessment presented in this study shows that the combined challenge and outbreak data are consistent with high infectivity of Aeromonas, and a wide range of susceptibility to acute enteric illness. To illustrate the outcomes, we simulate the risk associated with concentrations of Aeromonas found in different water and food matrices, indicating the disease burden potentially associated with these bacteria. In conclusion this study showed that Aeromonas is highly infectious, and that human susceptibility to illness may be high, similar to undisputed enteropathogens like Campylobacter or Salmonella. PMID- 27708622 TI - Antibacterial Activities of Wasabi against Escherichia coli O157:H7 and Staphylococcus aureus. AB - Escherichia coli O157:H7 and Staphylococcus aureus are two of the major pathogens frequently involved in foodborne outbreaks. Control of these pathogens in foods is essential to food safety. It is of great interest in the use of natural antimicrobial compounds present in edible plants to control foodborne pathogens as consumers prefer more natural "green" foods. Allyl isothiocyanate (AITC) is an antimicrobial compound naturally present in wasabi (Japanese horseradish) and several other edible plants. Although the antibacterial effects of pure AITC and wasabi extract (essential oil) against several bacteria have been reported, the antibacterial property of natural wasabi has not been well studied. This study investigated the antibacterial activities of wasabi as well as AITC against E. coli O157:H7 and S. aureus. Chemical analysis showed that AITC is the major isothiocyanate in wasabi. The AITC concentration in the wasabi powder used in this study was 5.91 +/- 0.59 mg/g. The minimum inhibitory concentration (MIC) of wasabi against E. coli O157:H7 or S. aureus was 1% (or 10 mg/ml). Wasabi at 4% displayed higher bactericidal activity against S. aureus than against E. coli O157:H7. The MIC of AITC against either pathogen was between 10 and 100 MUg/ml. AITC at 500 MUg/ml was bactericidal against both pathogens while AITC at 1000 MUg/ml eliminated E. coli O157:H7 much faster than S. aureus. The results from this study showed that wasabi has strong antibacterial property and has high potential to effectively control E. coli O157:H7 and S. aureus in foods. The antibacterial property along with its natural green color, unique flavor, and advantage to safeguard foods at the point of ingestion makes wasabi a promising natural edible antibacterial plant. The results from this study may be of significant interest to the food industry as they develop new and safe foods. These results may also stimulate more research to evaluate the antibacterial effect of wasabi against other foodborne pathogens and to explore other edible plants for their antimicrobial properties. To our knowledge, this is the first report on the antibacterial activity of wasabi in its natural form of consumption against E. coli O157:H7 and S. aureus.

AB - Probiotics which do not result in the development and spread of microbial resistance are among the candidate replacements for antibiotics previously used as growth promotors. In this study the effect of in-feed supplementation of the butyrate producing Butyricicoccus pullicaecorum strain 25-3T on performance, intestinal microbiota and prevention of necrotic enteritis (NE), a disease caused by Clostridium perfringens was evaluated in broilers. For the performance study, day old Ross 308 chicks were randomly allocated into two treatment groups and fed either a non-supplemented diet or a diet supplemented with 109 cfu lyophilized B. pullicaecorum per kg feed for 40 days. On day 40 broilers administered B. pullicaecorum had a significant lower bodyweight (2675 g vs. 2762 g; p = 0.0025) but supplementation of B. pullicaecorum decreased the feed conversion ratio significantly (1.518 vs. 1.632; p < 0.0001). Additionally, ingestion of the Butyricicoccus strain significantly lowered the abundance of Campylobacter spp. in the caecum and Enterococcus and Escherichia/Shigella spp. in the ileum at day 40. In feed supplementation of B. pullicaecorum in the NE trials resulted in a significant decrease in the number of birds with necrotic lesions compared with the untreated control group. These studies show that supplementation of B. pullicaecorum is able to improve feed conversion, to reduce the abundance of some potentially important pathogens in the caeca and ileum and to contribute to the prevention of NE in broilers, making the strain a potential valuable probiotic. PMID- 27708623 TI - Biostimulation of Indigenous Microbial Community for Bioremediation of Petroleum Refinery Sludge. AB - Nutrient deficiency severely impairs the catabolic activity of indigenous microorganisms in hydrocarbon rich environments (HREs) and limits the rate of intrinsic bioremediation. The present study aimed to characterize the microbial community in refinery waste and evaluate the scope for biostimulation based in situ bioremediation. Samples recovered from the wastewater lagoon of Guwahati refinery revealed a hydrocarbon enriched [high total petroleum hydrocarbon (TPH)], oxygen-, moisture-limited, reducing environment. Intrinsic biodegradation ability of the indigenous microorganisms was enhanced significantly (>80% reduction in TPH by 90 days) with nitrate amendment. Preferred utilization of both higher- (>C30) and middle- chain (C20-30) length hydrocarbons were evident from GC-MS analysis. Denaturing gradient gel electrophoresis and community level physiological profiling analyses indicated distinct shift in community's composition and metabolic abilities following nitrogen (N) amendment. High throughput deep sequencing of 16S rRNA gene showed that the native community was mainly composed of hydrocarbon degrading, syntrophic, methanogenic, nitrate/iron/sulfur reducing facultative anaerobic bacteria and archaebacteria, affiliated to gamma- and delta-Proteobacteria and Euryarchaeota respectively. Genes for aerobic and anaerobic alkane metabolism (alkB and bssA), methanogenesis (mcrA), denitrification (nirS and narG) and N2 fixation (nifH) were detected. Concomitant to hydrocarbon degradation, lowering of dissolve O2 and increase in oxidation-reduction potential (ORP) marked with an enrichment of N2 fixing, nitrate reducing aerobic/facultative anaerobic members [e.g., Azovibrio, Pseudoxanthomonas and Comamonadaceae members] was evident in N amended microcosm. This study highlighted that indigenous community of refinery sludge was intrinsically diverse, yet appreciable rate of in situ bioremediation could be achieved by supplying adequate N sources. PMID- 27708625 TI - Development of an in vitro Assay, Based on the BioFilm Ring Test(r), for Rapid Profiling of Biofilm-Growing Bacteria. AB - Microbial biofilm represents a major virulence factor associated with chronic and recurrent infections. Pathogenic bacteria embedded in biofilms are highly resistant to environmental and chemical agents, including antibiotics and therefore difficult to eradicate. Thus, reliable tests to assess biofilm formation by bacterial strains as well as the impact of chemicals or antibiotics on biofilm formation represent desirable tools for a most effective therapeutic management and microbiological risk control. Current methods to evaluate biofilm formation are usually time-consuming, costly, and hardly applicable in the clinical setting. The aim of the present study was to develop and assess a simple and reliable in vitro procedure for the characterization of biofilm-producing bacterial strains for future clinical applications based on the BioFilm Ring Test(r) (BRT) technology. The procedure developed for clinical testing (cBRT) can provide an accurate and timely (5 h) measurement of biofilm formation for the most common pathogenic bacteria seen in clinical practice. The results gathered by the cBRT assay were in agreement with the traditional crystal violet (CV) staining test, according to the kappa coefficient test (kappa = 0.623). However, the cBRT assay showed higher levels of specificity (92.2%) and accuracy (88.1%) as compared to CV. The results indicate that this procedure offers an easy, rapid and robust assay to test microbial biofilm and a promising tool for clinical microbiology. PMID- 27708626 TI - From Mouth to Model: Combining in vivo and in vitro Oral Biofilm Growth. AB - Background: Oral biofilm studies based on simplified experimental setups are difficult to interpret. Models are limited mostly by the number of bacterial species observed and the insufficiency of artificial media. Few studies have attempted to overcome these limitations and to cultivate native oral biofilm. Aims: This study aimed to grow oral biofilm in vivo before transfer to a biofilm reactor for ex situ incubation. The in vitro survival of this oral biofilm and the changes in bacterial composition over time were observed. Methods: Six human enamel-dentin slabs embedded buccally in dental splints were used as biofilm carriers. Fitted individually to the upper jaw of 25 non-smoking male volunteers, the splints were worn continuously for 48 h. During this time, tooth-brushing and alcohol-consumption were not permitted. The biofilm was then transferred on slabs into a biofilm reactor and incubated there for 48 h while being nourished in BHI medium. Live/dead staining and confocal laser scanning microscopy were used to observe bacterial survival over four points in time: directly after removal (T0) and after 1 (T1), 24 (T2), and 48 h (T3) of incubation. Bacterial diversity at T0 and T3 was compared with 454-pyrosequencing. Fluorescence in situ hybridization (FISH) was performed to show specific taxa. Survival curves were calculated with a specially designed MATLAB script. Acacia and QIIME 1.9.1 were used to process pyrosequencing data. SPSS 21.0 and R 3.3.1 were used for statistical analysis. Results: After initial fluctuations at T1, survival curves mostly showed approximation of the bacterial numbers to the initial level at T3. Pyrosequencing analysis resulted in 117 OTUs common to all samples. The genera Streptococcus and Veillonella (both Firmicutes) dominated at T0 and T3. They make up two thirds of the biofilm. Genera with lower relative abundance had grown significantly at T3. FISH analysis confirmed the pyrosequencing results, i.e., the predominant staining of Firmicutes. Conclusion: We demonstrate the in vitro survival of native primary oral biofilm in its natural complexity over 48 h. Our results offer a baseline for cultivation studies of native oral biofilms in (phyto-) pharmacological and dental materials research. Further investigations and validation of culturing conditions could also facilitate the study of biofilm induced diseases. PMID- 27708627 TI - A Phenotypic and Genotypic Analysis of the Antimicrobial Potential of Cultivable Streptomyces Isolated from Cave Moonmilk Deposits. AB - Moonmilk speleothems of limestone caves host a rich microbiome, among which Actinobacteria represent one of the most abundant phyla. Ancient medical texts reported that moonmilk had therapeutical properties, thereby suggesting that its filamentous endemic actinobacterial population might be a source of natural products useful in human treatment. In this work, a screening approach was undertaken in order to isolate cultivable Actinobacteria from moonmilk of the Grotte des Collemboles in Belgium, to evaluate their taxonomic profile, and to assess their potential in biosynthesis of antimicrobials. Phylogenetic analysis revealed that all 78 isolates were exclusively affiliated to the genus Streptomyces and clustered into 31 distinct phylotypes displaying various pigmentation patterns and morphological features. Phylotype representatives were tested for antibacterial and antifungal activities and their genomes were mined for secondary metabolite biosynthetic genes coding for non-ribosomal peptide synthetases (NRPSs), and polyketide synthases (PKS). The moonmilk Streptomyces collection was found to display strong inhibitory activities against a wide range of reference organisms, as 94, 71, and 94% of the isolates inhibited or impaired the growth of Gram-positive, Gram-negative bacteria, and fungi, respectively. Interestingly, 90% of the cave strains induced strong growth suppression against the multi-drug resistant Rasamsonia argillacea, a causative agent of invasive mycosis in cystic fibrosis and chronic granulomatous diseases. No correlation was observed between the global antimicrobial activity of an individual strain and the number of NRPS and PKS genes predicted in its genome, suggesting that approaches for awakening cryptic metabolites biosynthesis should be applied to isolates with no antimicrobial phenotype. Overall, our work supports the common belief that moonmilk might effectively treat various infectious diseases thanks to the presence of a highly diverse population of prolific antimicrobial producing Streptomyces, and thus may indeed constitute a promising reservoir of potentially novel active natural compounds. PMID- 27708628 TI - Quantitative Proteomic Analysis of Germination of Nosema bombycis Spores under Extremely Alkaline Conditions. AB - The microsporidian Nosema bombycis is an obligate intracellular pathogen of the silkworm Bombyx mori, causing the epidemic disease Pebrine and extensive economic losses in sericulture. Although N. bombycis forms spores with rigid spore walls that protect against various environmental pressures, ingested spores germinate immediately under the extremely alkaline host gut condition (Lepidoptera gut pH > 10.5), which is a key developmental turning point from dormant state to infected state. However, to date this process remains poorly understood due to the complexity of the animal digestive tract and the lack of genetic tools for microsporidia. Here we show, using an in vitro spore germination model, how the proteome of N. bombycis changes during germination, analyse specific metabolic pathways employed in detail, and validate key functional proteins in vivo in silkworms. By a label-free quantitative proteomics approach that is directly based on high-resolution mass spectrometry (MS) data, a total of 1136 proteins were identified with high confidence, with 127 proteins being significantly changed in comparison to non-germinated spores. Among them, structural proteins including polar tube protein 1 and 3 and spore wall protein (SWP) 4 and 30 were found to be significantly down-regulated, but SWP9 significantly up-regulated. Some nucleases like polynucleotide kinase/phosphatase and flap endonucleases 1, together with a panel of hydrolases involved in protein degradation and RNA cleavage were overrepresented too upon germination, which implied that they might play important roles during spore germination. The differentially regulated trends of these genes were validated, respectively, by quantitative RT-PCR and 3 proteins of interest were confirmed by Western blotting analyses in vitro and in vivo. Furthermore, the pathway analysis showed that abundant up- and down regulations appear involved in the glycolysis, pentose phosphate pathway, purine, and pyrimidine metabolism, suggesting preparations of energy generation and substance synthesis for the following invasion and proliferation inside the host. This report, to our knowledge, provides the first proteomic landscape of N. bombycis spores, and also a stepping stone on the way to further study of the unique infection mode of this economically important pathogen and other microsporidia in general. PMID- 27708629 TI - Upstream Freshwater and Terrestrial Sources Are Differentially Reflected in the Bacterial Community Structure along a Small Arctic River and Its Estuary. AB - Glacier melting and altered precipitation patterns influence Arctic freshwater and coastal ecosystems. Arctic rivers are central to Arctic water ecosystems by linking glacier meltwaters and precipitation with the ocean through transport of particulate matter and microorganisms. However, the impact of different water sources on the microbial communities in Arctic rivers and estuaries remains unknown. In this study we used 16S rRNA gene amplicon sequencing to assess a small river and its estuary on the Disko Island, West Greenland (69 degrees N). Samples were taken in August when there is maximum precipitation and temperatures are high in the Disko Bay area. We describe the bacterial community through a river into the estuary, including communities originating in a glacier and a proglacial lake. Our results show that water from the glacier and lake transports distinct communities into the river in terms of diversity and community composition. Bacteria of terrestrial origin were among the dominating OTUs in the main river, while the glacier and lake supplied the river with water containing fewer terrestrial organisms. Also, more psychrophilic taxa were found in the community supplied by the lake. At the river mouth, the presence of dominant bacterial taxa from the lake and glacier was unnoticeable, but these taxa increased their abundances again further into the estuary. On average 23% of the estuary community consisted of indicator OTUs from different sites along the river. Environmental variables showed only weak correlations with community composition, suggesting that hydrology largely influences the observed patterns. PMID- 27708631 TI - Suspension Array for Multiplex Detection of Eight Fungicide-Resistance Related Alleles in Botrytis cinerea. AB - A simple and high-throughput assay to detect fungicide resistance is required for large-scale monitoring of the emergence of resistant strains of Botrytis cinerea. Using suspension array technology performed on a Bio-Plex 200 System, we developed a single-tube allele-specific primer extension assay that can simultaneously detect eight alleles in one reaction. These eight alleles include E198 and 198A of the beta-Tubulin gene (BenA), H272 and 272Y of the Succinate dehydrogenase iron-sulfur subunit gene (SdhB), I365 and 365S of the putative osmosensor histidine kinase gene (BcOS1), and F412 and 412S of the 3 ketoreductase gene (erg27). This assay was first established and optimized with eight plasmid templates containing the DNA sequence variants BenA-E198, BenA 198A, SdhB-H272, SdhB-272Y, BcOS1-I365, BcOS1-365S, erg27-F412, and erg27-412S. Results indicated that none of the probes showed cross-reactivity with one another. The minimum limit of detection for these genotypes was one copy per test. Four mutant plasmids were mixed with 10 ng/MUL wild-type genomic DNA in different ratios. Detection sensitivity of mutant loci was 0.45% for BenA-E198A, BcOS1-I365S, and erg27-F412S, and was 4.5% for SdhB-H272Y. A minimum quantity of 0.1 ng of genomic DNA was necessary to obtain reliable results. This is the first reported assay that can simultaneously detect mutations in BenA, SdhB, BcOS1, and erg27. PMID- 27708630 TI - Beyond 16S rRNA Community Profiling: Intra-Species Diversity in the Gut Microbiota. AB - Interactions with microbes affect many aspects of animal biology, including immune system development, nutrition and health. In vertebrates, the gut microbiota is dominated by a small subset of phyla, but the species composition within these phyla is typically not conserved. Moreover, several recent studies have shown that bacterial species in the gut are composed of a multitude of strains, which frequently co-exist in their host, and may be host-specific. However, since the study of intra-species diversity is challenging, particularly in the setting of complex, host-associated microbial communities, our current understanding of the distribution, evolution and functional relevance of intra species diversity in the gut is scarce. In order to unravel how genomic diversity translates into phenotypic diversity, community analyses going beyond 16S rRNA profiling, in combination with experimental approaches, are needed. Recently, the honeybee has emerged as a promising model for studying gut bacterial communities, particularly in terms of strain-level diversity. Unlike most other invertebrates, the honeybee gut is colonized by a remarkably consistent and specific core microbiota, which is dominated by only eight bacterial species. As for the vertebrate gut microbiota, these species are composed of highly diverse strains suggesting that similar evolutionary forces shape gut community structures in vertebrates and social insects. In this review, we outline current knowledge on the evolution and functional relevance of strain diversity within the gut microbiota, including recent insights gained from mammals and other animals such as the honeybee. We discuss methodological approaches and propose possible future avenues for studying strain diversity in complex bacterial communities. PMID- 27708633 TI - Persistent Infection by Wolbachia wAlbB Has No Effect on Composition of the Gut Microbiota in Adult Female Anopheles stephensi. AB - The bacteria in the midgut of Anopheles stephensi adult females from laboratory colonies were studied by sequencing the V4 region of 16S rRNA genes, with respect to three experimental factors: stable or cured Wolbachia infection; sugar or blood diet; and age. Proteobacteria and Bacteroidetes dominated the community [>90% of operational taxonomic units (OTUs)]; most taxa were in the classes Flavobacteriia, Gammaproteobacteria, and Alphaproteobacteria, and were assigned to Elizabethkingia (46.9%), Asaia (6.4%) and Pseudomonas (6.0%), or unclassified Enterobacteriaceae (37.2%). Bacterial communities were similar between Wolbachia cured and Wolbachia-infected mosquito lines, indicating that the gut microbiota were not dysregulated in the presence of Wolbachia. The proportion of Enterobacteriaceae was higher in mosquitoes fed a blood meal compared to those provided a sugar meal. Collectively, the bacterial community had a similar structure in older Wolbachia-infected mosquitoes 8 days after the blood meal, as in younger Wolbachia-infected mosquitoes before a blood meal, except that older mosquitoes had a higher proportion of Enterobacteriaceae and lower proportion of Elizabethkingia. Consistent presence of certain predominant bacteria (Elizabethkingia, Asaia, Pseudomonas, and Enterobacteriaceae) suggests they would be useful for paratransgenesis to control malaria infection, particularly when coupled to a Wolbachia-based intervention strategy. PMID- 27708634 TI - Localization of Components of the RNA-Degrading Machine in Bacillus subtilis. AB - In bacteria, the control of mRNA stability is crucial to allow rapid adaptation to changing conditions. In most bacteria, RNA degradation is catalyzed by the RNA degradosome, a protein complex composed of endo- and exoribonucleases, RNA helicases, and accessory proteins. In the Gram-positive model organism Bacillus subtilis, the existence of a RNA degradosome assembled around the membrane-bound endoribonuclease RNase Y has been proposed. Here, we have studied the intracellular localization of the protein that have been implicated in the potential B. subtilis RNA degradosome, i.e., polynucleotide phosphorylase, the exoribonucleases J1 and J2, the DEAD-box RNA helicase CshA, and the glycolytic enzymes enolase and phosphofructokinase. Our data suggests that the bulk of these enzymes is located in the cytoplasm. The RNases J1 and J2 as well as the RNA helicase CshA were mainly localized in the peripheral regions of the cell where also the bulk of messenger RNA is localized. We were able to demonstrate active exclusion of these proteins from the transcribing nucleoid. Taken together, our findings suggest that the interactions of the enzymes involved in RNA degradation in B. subtilis are rather transient.

PMID- 27708632 TI - Multidrug Efflux Pumps at the Crossroad between Antibiotic Resistance and Bacterial Virulence. AB - Multidrug efflux pumps can be involved in bacterial resistance to antibiotics at different levels. Some efflux pumps are constitutively expressed at low levels and contribute to intrinsic resistance. In addition, their overexpression may allow higher levels of resistance. This overexpression can be transient, in the presence of an effector (phenotypic resistance), or constitutive when mutants in the regulatory elements of the expression of efflux pumps are selected (acquired resistance). Efflux pumps are present in all cells, from human to bacteria and are highly conserved, which indicates that they are ancient elements in the evolution of different organisms. Consequently, it has been suggested that, besides antibiotic resistance, bacterial multidrug efflux pumps would likely contribute to other relevant processes of the microbial physiology. In the current article, we discuss some specific examples of the role that efflux pumps may have in the bacterial virulence of animals' and plants' pathogens, including the processes of intercellular communication. Based in these evidences, we propose that efflux pumps are at the crossroad between resistance and virulence of bacterial pathogens. Consequently, the comprehensive study of multidrug efflux pumps requires addressing these functions, which are of relevance for the bacterial-host interactions during infection. PMID- 27708635 TI - The Kinome of Edible and Medicinal Fungus Wolfiporia cocos. AB - Wolfiporia cocos is an edible and medicinal fungus that grows in association with pine trees, and its dried sclerotium, known as Fuling in China, has been used as a traditional medicine in East Asian countries for centuries. Nearly 10% of the traditional Chinese medicinal preparations contain W. cocos. Currently, the commercial production of Fuling is limited because of the lack of pine-based substrate and paucity of knowledge about the sclerotial development of the fungus. Since protein kinase (PKs) play significant roles in the regulation of growth, development, reproduction, and environmental responses in filamentous fungi, the kinome of W. cocos was analyzed by identifying the PKs genes, studying transcript profiles and assigning PKs to orthologous groups. Of the 10 putative PKs, 11 encode atypical PKs, and 13, 10, 2, 22, and 11 could encoded PKs from the AGC, CAMK, CK, CMGC, STE, and TLK Groups, respectively. The level of transcripts from PK genes associated with sclerotia formation in the mycelium and sclerotium stages were analyzed by qRT-PCR. Based on the functions of the orthologs in Sclerotinia sclerotiorum (a sclerotia-formation fungus) and Saccharomyces cerevisiae, the potential roles of these W. cocos PKs were assigned. To the best of our knowledge, our study is the first identification and functional discussion of the kinome in the edible and medicinal fungus W. cocos. Our study systematically suggests potential roles of W. cocos PKs and provide comprehensive and novel insights into W. cocos sclerotial development and other economically important traits. Additionally, based on our result, genetic engineering can be employed for over expression or interference of some significant PKs genes to promote sclerotial growth and the accumulation of active compounds. PMID- 27708637 TI - Microbiome Dynamics of a Polychlorobiphenyl (PCB) Historically Contaminated Marine Sediment under Conditions Promoting Reductive Dechlorination. AB - The toxicity of polychlorinated biphenyls (PCB) can be efficiently reduced in contaminated marine sediments through the reductive dechlorination (RD) process lead by anaerobic organohalide bacteria. Although the process has been extensively investigated on PCB-spiked sediments, the knowledge on the identity and metabolic potential of PCB-dechlorinating microorganisms in real contaminated matrix is still limited. Aim of this study was to explore the composition and the dynamics of the microbial communities of the marine sediment collected from one of the largest Sites of National Interest (SIN) in Italy (Mar Piccolo, Taranto) under conditions promoting the PCBs RD. A long-term microcosm study revealed that autochthonous bacteria were able to sustain the PCB dechlorination at a high extent and the successive addition of an external fermentable organic substrate (lactate) caused the further depletion of the high-chlorinated PCBs (up to 70%). Next Generation Sequencing was used to describe the core microbiome of the marine sediment and to follow the changes caused by the treatments. OTUs affiliated to sulfur-oxidizing epsilon-proteobacteria, Sulfurovum, and Sulfurimonas, were predominant in the original sediment and increased up to 60% of total OTUs after lactate addition. Other OTUs detected in the sediment were affiliated to sulfate reducing (delta-proteobacteria) and to organohalide respiring bacteria within Chloroflexi phylum mainly belonging to Dehalococcoidia class. Among others, Dehalococcoides mccartyi was enriched during the treatments even though the screening of the specific reductive dehalogenase genes revealed the occurrence of undescribed strains, which deserve further investigations. Overall, this study highlighted the potential of members of Dehalococcoidia class in reducing the contamination level of the marine sediment from Mar Piccolo with relevant implications on the selection of sustainable bioremediation strategies to clean up the site. PMID- 27708638 TI - Rhamnolipid Biosurfactant against Fusarium verticillioides to Control Stalk and Ear Rot Disease of Maize. AB - Antifungal activity of rhamnolipids (RLs) has been widely studied against many plant pathogenic fungi, but not against Fusarium verticillioides, a major pathogen of maize (Zea mays L.). F. verticillioides causes stalk and ear rot of maize or asymptomatically colonizes the plant and ears resulting in moderate to heavy crop loss throughout the world. F. verticillioides produces fumonisin mycotoxins, reported carcinogens, which makes the contaminated ears unsuitable for consumption. In this study, the RL produced using glucose as sole carbon source was characterized by FTIR and LCMS analyses and its antifungal activity against F. verticillioides was evaluated in vitro on maize stalks and seeds. Further, the effect of RL on the mycelia of F. verticillioides was investigated by scanning electron microscopy which revealed visible damage to the mycelial structure as compared to control samples. In planta, treatment of maize seeds with a RL concentration of 50 mg l-1 resulted in improved biomass and fruiting compared to those of healthy control plants and complete suppression of characteristic disease symptoms and colonization of maize by F. verticillioides. The study highlights the potential of RLs to be used for an effective biocontrol strategy against colonization of maize plant by F. verticillioides. PMID- 27708639 TI - The Synergistic Effect of High Pressure CO2 and Nisin on Inactivation of Bacillus subtilis Spores in Aqueous Solutions. AB - The inactivation effects of high pressure CO2 + nisin (simultaneous treatment of HPCD and nisin, HPCD + nisin), HPCD->nisin (HPCD was followed by nisin), and nisin->HPCD (nisin was followed by HPCD) treatments on Bacillus subtilis spores in aqueous solutions were compared. The spores were treated by HPCD at 6.5 or 20 MPa, 84-86 degrees C and 0-30 min, and the concentration of nisin was 0.02%. Treated spores were examined for the viability, the permeability of inner membrane (IM) using flow cytometry method and pyridine-2, 6-dicarboxylic acid (DPA) release, and structural damage by transmission electron microscopy. A synergistic effect of HPCD + nisin treatment on inactivation of the spores was found, and the inactivation efficiency of the spores was HPCD + nisin > HPCD >nisin or nisin->HPCD. Moreover, HPCD + nisin caused higher IM permeability and DPA release of the spores than HPCD. A possible action mode of nisin-enhanced inactivation of the spores was suggested as that HPCD firstly damaged the coat and cortex of spores, and nisin penetrated into and acted on the IM of spores, which increased the damage to the IM of spores, and resulted in higher inactivation of the spores. PMID- 27708640 TI - A Screening Method for the Isolation of Polyhydroxyalkanoate-Producing Purple Non sulfur Photosynthetic Bacteria from Natural Seawater. AB - Polyhydroxyalkanoates (PHAs) are a family of biopolyesters accumulated by a variety of microorganisms as carbon and energy storage under starvation conditions. We focused on marine purple non-sulfur photosynthetic bacteria as host microorganisms for PHA production and developed a method for their isolation from natural seawater. To identify novel PHA-producing marine purple non-sulfur photosynthetic bacteria, natural seawaters were cultured in nutrient-rich medium for purple non-sulfur photosynthetic bacteria, and twelve pink- or red-pigmented colonies were picked up. Gas chromatography mass spectrometry analysis revealed that four isolates synthesized PHA at levels ranging from 0.5 to 24.4 wt% of cell dry weight. The 16S ribosomal RNA sequence analysis revealed that one isolate (HM2) showed 100% identity to marine purple non-sulfur photosynthetic bacteria. In conclusion, we have demonstrated in this study that PHA-producing marine purple non-sulfur photosynthetic bacteria can be isolated from natural seawater under nutrient-rich conditions. PMID- 27708641 TI - Differences in the Composition of Archaeal Communities in Sediments from Contrasting Zones of Lake Taihu. AB - In shallow lakes, different primary producers might impact the physiochemical characteristics of the sediment and the associated microbial communities. Until now, little was known about the features of sediment Archaea and their variation across different primary producer-dominated ecosystems. Lake Taihu provides a suitable study area with cyanobacteria- and macrophyte-dominated zones co occurring in one ecosystem. The composition of the sediment archaeal community was assessed using 16S rRNA gene amplicon sequencing technology, based on which the potential variation with respect to the physiochemical characteristics of the sediment was analyzed. Euryarchaeota (30.19% of total archaeal sequences) and Bathyarchaeota (28.00%) were the two most abundant phyla, followed by Crenarchaeota (11.37%), Aigarchaeota (10.24%) and Thaumarchaeota (5.98%). The differences found in the composition of the archaeal communities between the two zones was significant (p = 0.005). Sediment from macrophyte-dominated zones had high TOC and TN content and an abundance of archaeal lineages potentially involved in the degradation of complex organic compounds, such as the order Thermoplasmatales. In the area dominated by Cyanobacteria, archaeal lineages related to sulfur metabolism, for example, Sulfolobales and Desulfurococcales, were significantly enriched. Among Bathyarchaeota, subgroups MCG-6 and MCG-15 were significantly accumulated in the sediment of areas dominated by macrophytes whereas MCG-4 was consistently dominant in both type of sediments. The present study contributes to the knowledge of sediment archaeal communities with different primary producers and their possible biogeochemical functions in sediment habitats. PMID- 27708642 TI - HIV Latency-Reversing Agents Have Diverse Effects on Natural Killer Cell Function. AB - In an effort to clear persistent HIV infection and achieve a durable therapy-free remission of HIV disease, extensive pre-clinical studies and early pilot clinical trials are underway to develop and test agents that can reverse latent HIV infection and present viral antigen to the immune system for clearance. It is, therefore, critical to understand the impact of latency-reversing agents (LRAs) on the function of immune effectors needed to clear infected cells. We assessed the impact of LRAs on the function of natural killer (NK) cells, the main effector cells of the innate immune system. We studied the effects of three histone deacetylase inhibitors [SAHA or vorinostat (VOR), romidepsin, and panobinostat (PNB)] and two protein kinase C agonists [prostratin (PROST) and ingenol] on the antiviral activity, cytotoxicity, cytokine secretion, phenotype, and viability of primary NK cells. We found that ex vivo exposure to VOR had minimal impact on all parameters assessed, while PNB caused a decrease in NK cell viability, antiviral activity, and cytotoxicity. PROST caused non-specific NK cell activation and, interestingly, improved antiviral activity. Overall, we found that LRAs can alter the function and fate of NK cells, and these effects must be carefully considered as strategies are developed to clear persistent HIV infection. PMID- 27708643 TI - Differential Regulation of Self-reactive CD4+ T Cells in Cervical Lymph Nodes and Central Nervous System during Viral Encephalomyelitis. AB - Viral infections have long been implicated as triggers of autoimmune diseases, including multiple sclerosis (MS), a central nervous system (CNS) inflammatory demyelinating disorder. Epitope spreading, molecular mimicry, cryptic antigen, and bystander activation have been implicated as mechanisms responsible for activating self-reactive (SR) immune cells, ultimately leading to organ-specific autoimmune disease. Taking advantage of coronavirus JHM strain of mouse hepatitis virus (JHMV)-induced demyelination, this study demonstrates that the host also mounts counteractive measures to specifically limit expansion of endogenous SR T cells. In this model, immune-mediated demyelination is associated with induction of SR T cells after viral control. However, their decline during persisting infection, despite ongoing demyelination, suggests an active control mechanism. Antigen-specific IL-10-secreting CD4+ T cells (Tr1) and Foxp3+ regulatory T cells (Tregs), both known to control autoimmunity and induced following JHMV infection, were assessed for their relative in vivo suppressive function of SR T cells. Ablation of Foxp3+ Tregs in chronically infected DEREG mice significantly increased SR CD4+ T cells within cervical lymph nodes (CLN), albeit without affecting their numbers or activation within the CNS compared to controls. In contrast, infected IL-27 receptor deficient (IL-27R-/-) mice, characterized by a drastic reduction of Tr1 cells, revealed that SR CD4+ T cells in CLN remained unchanged but were specifically increased within the CNS. These results suggest that distinct Treg subsets limit SR T cells in the draining lymph nodes and CNS to maximize suppression of SR T-cell-mediated autoimmune pathology. The JHMV model is thus valuable to decipher tissue-specific mechanisms preventing autoimmunity. PMID- 27708644 TI - Comparative Analysis of Immune Activation Markers of CD8+ T Cells in Lymph Nodes of Different Origins in SIV-Infected Chinese Rhesus Macaques. AB - Altered T-cell homeostasis, such as expansion of CD8+ T cells to the secondary lymphatic compartments, has been suggested as a mechanism of HIV/simian immunodeficiency virus (SIV)-pathogenesis. However, the role of immune activation of CD8+ T cells in the CD4/CD8 turnover and viral replication in these tissues is not completely understood. In this study, we compared the expression of immune activation markers (CD69 and HLA-DR) on CD8+ T cells in the peripheral blood and lymph nodes (LNs) of SIV-infected/uninfected Chinese rhesus macaques. SIV infected macaques had significantly higher percentages of CD8+CD69+ and CD8+HLA DR+ T cells in all these anatomical compartments than uninfected macaques. LNs that located close to the gastrointestinal (GI) tract (colon, mesenteric, and iliac LNs) of SIV-infected macaques had profoundly lower numbers of CD4+ T cells, but no significant difference in expression of activation marker (CD8+CD69+ and CD8+HLA-DR+) as compared with the peripheral lymphatic tissues (axillary and inguinal LNs). The CD4/CD8 ratios were negatively correlated with the activation of CD8+ T cells in the overall LNs, with further associations with CD8+HLA-DR+ in GI LNs while CD8+CD69+ in peripheral LNs. These observations demonstrate that the increase of CD8+ T cell activation is a contributing factor for the decline of CD4/CD8 ratios in GI system. PMID- 27708645 TI - SONAR: A High-Throughput Pipeline for Inferring Antibody Ontogenies from Longitudinal Sequencing of B Cell Transcripts. AB - The rapid advance of massively parallel or next-generation sequencing technologies has made possible the characterization of B cell receptor repertoires in ever greater detail, and these developments have triggered a proliferation of software tools for processing and annotating these data. Of especial interest, however, is the capability to track the development of specific antibody lineages across time, which remains beyond the scope of most current programs. We have previously reported on the use of techniques such as inter- and intradonor analysis and CDR3 tracing to identify transcripts related to an antibody of interest. Here, we present Software for the Ontogenic aNalysis of Antibody Repertoires (SONAR), capable of automating both general repertoire analysis and specialized techniques for investigating specific lineages. SONAR annotates next-generation sequencing data, identifies transcripts in a lineage of interest, and tracks lineage development across multiple time points. SONAR also generates figures, such as identity-divergence plots and longitudinal phylogenetic "birthday" trees, and provides interfaces to other programs such as DNAML and BEAST. SONAR can be downloaded as a ready-to-run Docker image or manually installed on a local machine. In the latter case, it can also be configured to take advantage of a high-performance computing cluster for the most computationally intensive steps, if available. In summary, this software provides a useful new tool for the processing of large next-generation sequencing datasets and the ontogenic analysis of neutralizing antibody lineages. SONAR can be found at https://github.com/scharch/SONAR, and the Docker image can be obtained from https://hub.docker.com/r/scharch/sonar/. PMID- 27708647 TI - Cherry Valley Ducks Mitochondrial Antiviral-Signaling Protein-Mediated Signaling Pathway and Antiviral Activity Research. AB - Mitochondrial antiviral-signaling protein (MAVS), an adaptor protein of retinoic acid-inducible gene I (RIG-I)-like receptors (RLRs)-mediated signal pathway, is involved in innate immunity. In this study, Cherry Valley duck MAVS (duMAVS) was cloned from the spleen and analyzed. duMAVS was determined to have a caspase activation and recruitment domain at N-terminal, followed by a proline-rich domain and a transmembrane domain at C-terminal. Quantitative real-time PCR indicated that duMAVS was expressed in all tissues tested across a broad expression spectrum. The expression of duMAVS was significantly upregulated after infection with duck Tembusu virus (DTMUV). Overexpression of duMAVS could drive the activation of interferon (IFN)-beta, nuclear factor-kappaB, interferon regulatory factor 7, and many downstream factors (such as Mx, PKR, OAS, and IL-8) in duck embryo fibroblast cells. What is more, RNA interference further confirmed that duMAVS was an important adaptor for IFN-beta activation. The antiviral assay showed that duMAVS could suppress the various viral replications (DTMUV, novel reovirus, and duck plague virus) at early stages of infection. Overall, these results showed that the main signal pathway mediated by duMAVS and it had a broad spectrum antiviral ability. This research will be helpful to better understanding the innate immune system of ducks. PMID- 27708646 TI - NETosis in Cancer - Platelet-Neutrophil Crosstalk Promotes Tumor-Associated Pathology. AB - It has become increasingly clear that circulating immune cells in the body have a major impact on cancer development, progression, and outcome. The role of both platelets and neutrophils as independent regulators of various processes in cancer has been known for long, but it has quite recently emerged that the platelet-neutrophil interplay is yet a critical component to take into account during malignant disease. It was reported a few years ago that neutrophils in mice with cancer have increased propensity to form neutrophil extracellular traps (NETs) - web-like structures formed by externalized chromatin and secreted proteases. The initial finding describing this as a cell death-associated process has been followed by reports of additional mechanisms for NET formation (NETosis), and it has been shown that similar structures can be formed also without lysis and neutrophil cell death as a consequence. Furthermore, presence of NETs in humans with cancer has been verified in a few recent studies, indicating that tumor-induced NETosis is clinically relevant. Several reports have also described that NETs contribute to cancer-associated pathology, by promoting processes responsible for cancer-related death such as thrombosis, systemic inflammation, and relapse of the disease. This review summarizes current knowledge about NETosis in cancer, including the role of platelets as regulators of tumor-induced NETosis. It has been shown that platelets can serve as inducers of NETosis, and the platelet-neutrophil interface can therefore be an important issue to consider when designing therapies targeting cancer-associated pathology in the future.

PMID- 27708648 TI - Generation of Marker- and/or Backbone-Free Transgenic Wheat Plants via Agrobacterium-Mediated Transformation. AB - Horizontal transfer of antibiotic resistance genes to animals and vertical transfer of herbicide resistance genes to the weedy relatives are perceived as major biosafety concerns in genetically modified (GM) crops. In this study, five novel vectors which used gusA and bar as a reporter gene and a selection marker gene, respectively, were constructed based on the pCLEAN dual binary vector system. Among these vectors, 1G7B and 5G7B carried two T-DNAs located on two respective plasmids with 5G7B possessing an additional virGwt gene. 5LBTG154 and 5TGTB154 carried two T-DNAs in the target plasmid with either one or double right borders, and 5BTG154 carried the selectable marker gene on the backbone outside of the T-DNA left border in the target plasmid. In addition, 5BTG154, 5LBTG154, and 5TGTB154 used pAL154 as a helper plasmid which contains Komari fragment to facilitate transformation. These five dual binary vector combinations were transformed into Agrobacterium strain AGL1 and used to transform durum wheat cv Stewart 63. Evaluation of the co-transformation efficiencies, the frequencies of marker-free transgenic plants, and integration of backbone sequences in the obtained transgenic lines indicated that two vectors (5G7B and 5TGTB154) were more efficient in generating marker-free transgenic wheat plants with no or minimal integration of backbone sequences in the wheat genome. The vector series developed in this study for generation of marker- and/or backbone-free transgenic wheat plants via Agrobacterium-mediated transformation will be useful to facilitate the creation of "clean" GM wheat containing only the foreign genes of agronomic importance. PMID- 27708650 TI - A Novel FC116/BC10 Mutation Distinctively Causes Alteration in the Expression of the Genes for Cell Wall Polymer Synthesis in Rice. AB - We report isolation and characterization of a fragile culm mutant fc116 that displays reduced mechanical strength caused by decreased cellulose content and altered cell wall structure in rice. Map-based cloning revealed that fc116 was a base substitution mutant (G to A) in a putative beta-1,6-N acetylglucosaminyltransferase (C2GnT) gene (LOC_Os05g07790, allelic to BC10). This mutation resulted in one amino acid missing within a newly-identified protein motif "R, RXG, RA." The FC116/BC10 gene was lowly but ubiquitously expressed in the all tissues examined across the whole life cycle of rice, and slightly down-regulated during secondary growth. This mutant also exhibited a significant increase in the content of hemicelluloses and lignins, as well as the content of pentoses (xylose and arabinose). But the content of hexoses (glucose, mannose, and galactose) was decreased in both cellulosic and non-cellulosic (pectins and hemicelluloses) fractions of the mutant. Transcriptomic analysis indicated that the typical genes in the fc116 mutant were up-regulated corresponding to xylan biosynthesis, as well as lignin biosynthesis including p hydroxyphenyl (H), syringyl (S), and guaiacyl (G). Our results indicate that FC116 has universal function in regulation of the cell wall polymers in rice. PMID- 27708649 TI - Gene Overexpression Resources in Cereals for Functional Genomics and Discovery of Useful Genes. AB - Identification and elucidation of functions of plant genes is valuable for both basic and applied research. In addition to natural variation in model plants, numerous loss-of-function resources have been produced by mutagenesis with chemicals, irradiation, or insertions of transposable elements or T-DNA. However, we may be unable to observe loss-of-function phenotypes for genes with functionally redundant homologs and for those essential for growth and development. To offset such disadvantages, gain-of-function transgenic resources have been exploited. Activation-tagged lines have been generated using obligatory overexpression of endogenous genes by random insertion of an enhancer. Recent progress in DNA sequencing technology and bioinformatics has enabled the preparation of genomewide collections of full-length cDNAs (fl-cDNAs) in some model species. Using the fl-cDNA clones, a novel gain-of-function strategy, Fl cDNA OvereXpressor gene (FOX)-hunting system, has been developed. A mutant phenotype in a FOX line can be directly attributed to the overexpressed fl-cDNA. Investigating a large population of FOX lines could reveal important genes conferring favorable phenotypes for crop breeding. Alternatively, a unique loss of-function approach Chimeric REpressor gene Silencing Technology (CRES-T) has been developed. In CRES-T, overexpression of a chimeric repressor, composed of the coding sequence of a transcription factor (TF) and short peptide designated as the repression domain, could interfere with the action of endogenous TF in plants. Although plant TFs usually consist of gene families, CRES-T is effective, in principle, even for the TFs with functional redundancy. In this review, we focus on the current status of the gene-overexpression strategies and resources for identifying and elucidating novel functions of cereal genes. We discuss the potential of these research tools for identifying useful genes and phenotypes for application in crop breeding. PMID- 27708652 TI - Melatonin-Producing Endophytic Bacteria from Grapevine Roots Promote the Abiotic Stress-Induced Production of Endogenous Melatonin in Their Hosts. AB - Endophytes form symbiotic relationships with plants and constitute an important source of phytohormones and bioactive secondary metabolites for their hosts. To date, most studies of endophytes have focused on the influence of these microorganisms on plant growth and physiology and their role in plant defenses against biotic and abiotic stressors; however, to the best of our knowledge, the ability of endophytes to produce melatonin has not been reported. In the present study, we isolated and identified root-dwelling bacteria from three grapevine varieties and found that, when cultured under laboratory conditions, some of the bacteria strains secreted melatonin and tryptophan-ethyl ester. The endophytic bacterium Bacillus amyloliquefaciens SB-9 exhibited the highest level of in vitro melatonin secretion and also produced three intermediates of the melatonin biosynthesis pathway: 5-hydroxytryptophan, serotonin, and N-acetylserotonin. After B. amyloliquefaciens SB-9 colonization, the plantlets exhibited increased plant growth. Additionally, we found that, in grapevine plantlets exposed to salt or drought stress, colonization by B. amyloliquefaciens SB-9 increased the upregulation of melatonin synthesis, as well as that of its intermediates, but reduced the upregulation of grapevine tryptophan decarboxylase genes (VvTDCs) and a serotonin N-acetyltransferase gene (VvSNAT) transcription, when compared to the un-inoculated control. Colonization by B. amyloliquefaciens SB-9 was also able to counteract the adverse effects of salt- and drought-induced stress by reducing the production of malondialdehyde and reactive oxygen species (H2O2 and O2-) in roots. Therefore, our findings demonstrate the occurrence of melatonin biosynthesis in endophytic bacteria and provide evidence for a novel form of communication between beneficial endophytes and host plants via melatonin. PMID- 27708654 TI - The 4-Dimensional Plant: Effects of Wind-Induced Canopy Movement on Light Fluctuations and Photosynthesis. AB - Physical perturbation of a plant canopy brought about by wind is a ubiquitous phenomenon and yet its biological importance has often been overlooked. This is partly due to the complexity of the issue at hand: wind-induced movement (or mechanical excitation) is a stochastic process which is difficult to measure and quantify; plant motion is dependent upon canopy architectural features which, until recently, were difficult to accurately represent and model in 3-dimensions; light patterning throughout a canopy is difficult to compute at high-resolutions, especially when confounded by other environmental variables. Recent studies have reinforced the expectation that canopy architecture is a strong determinant of productivity and yield; however, links between the architectural properties of the plant and its mechanical properties, particularly its response to wind, are relatively unknown. As a result, biologically relevant data relating canopy architecture, light- dynamics, and short-scale photosynthetic responses in the canopy setting are scarce. Here, we hypothesize that wind-induced movement will have large consequences for the photosynthetic productivity of our crops due to its influence on light patterning. To address this issue, in this study we combined high resolution 3D reconstructions of a plant canopy with a simple representation of canopy perturbation as a result of wind using solid body rotation in order to explore the potential effects on light patterning, interception, and photosynthetic productivity. We looked at two different scenarios: firstly a constant distortion where a rice canopy was subject to a permanent distortion throughout the whole day; and secondly, a dynamic distortion, where the canopy was distorted in incremental steps between two extremes at set time points in the day. We find that mechanical canopy excitation substantially alters light dynamics; light distribution and modeled canopy carbon gain. We then discuss methods required for accurate modeling of mechanical canopy excitation (here coined the 4-dimensional plant) and some associated biological and applied implications of such techniques. We hypothesize that biomechanical plant properties are a specific adaptation to achieve wind-induced photosynthetic enhancement and we outline how traits facilitating canopy excitation could be used as a route for improving crop yield. PMID- 27708653 TI - Transporters Involved in Root Nitrate Uptake and Sensing by Arabidopsis. AB - Most plants use nitrate (NO3-) as their major nitrogen (N) source. The NO3- uptake capacity of a plant is determined by three interdependent factors that are sensitive to NO3- availability: (i) the functional properties of the transporters in roots that contribute to the acquisition of NO3- from the external medium, (ii) the density of functional transporters at the plasma membrane of root cells, and (iii) the surface and architecture of the root system. The identification of factors that regulate the NO3--sensing systems is important for both fundamental and applied science, because these factors control the capacity of plants to use the available NO3-, a process known as the "nitrate use efficiency." The molecular component of the transporters involved in uptake and sensing mechanism in Arabidopsis roots are presented and their relative contribution discussed. PMID- 27708655 TI - Proteomic Analysis Reveals Different Involvement of Embryo and Endosperm Proteins during Aging of Yliangyou 2 Hybrid Rice Seeds. AB - Seed aging is a process that results in a delayed germination, a decreased germination percentage, and finally a total loss of seed viability. However, the mechanism of seed aging is poorly understood. In the present study, Yliangyou 2 hybrid rice (Oryza sativa L.) seeds were artificially aged at 100% relative humidity and 40 degrees C, and the effect of artificial aging on germination, germination time course and the change in protein profiles of embryo and endosperm was studied to understand the molecular mechanism behind seed aging. With an increasing duration of artificial aging, the germination percentage and germination rate of hybrid rice seeds decreased. By comparing the protein profiles from the seeds aged for 0, 10 and 25 days, a total of 91 and 100 protein spots were found to show a significant change of more than 2-fold (P < 0.05) in abundance, and 71 and 79 protein spots were identified, in embryos and endosperms, respectively. The great majority of these proteins increased in abundance in embryos (95%) and decreased in abundance in endosperms (99%). In embryos, most of the identified proteins were associated with energy (30%), with cell defense and rescue (28%), and with storage protein (18%). In endosperms, most of the identified proteins were involved in metabolism (37%), in energy (27%), and in protein synthesis and destination (11%). The most marked change was the increased abundance of many glycolytic enzymes together with the two fermentation enzymes pyruvate decarboxylase and alcohol dehydrogenase in the embryos during aging. We hypothesize that the decreased viability of hybrid rice seeds during artificial aging is caused by the development of hypoxic conditions in the embryos followed by ethanol accumulation. PMID- 27708656 TI - Transcriptome Analysis of Stem and Globally Comparison with Other Tissues in Brassica napus. AB - Brassica napus is one of the most important oilseed crops in the world. However, there is currently no enough stem transcriptome information and comparative transcriptome analysis of different tissues, which impedes further functional genomics research on B. napus. In this study, the stem transcriptome of B. napus was characterized by RNA-seq technology. Approximately 13.4 Gb high-quality clean reads with an average length of 100 bp were generated and used for comparative transcriptome analysis with the existing transcriptome sequencing data of roots, leaves, flower buds, and immature embryos of B. napus. All the transcripts were annotated against GO and KEGG databases. The common genes in five tissues, differentially expressed genes (DEGs) of the common genes between stems and other tissues, and tissue-specific genes were detected, and the main biochemical activities and pathways implying the common genes, DEGs and tissue-specific genes were investigated. Accordingly, the common transcription factors (TFs) in the five tissues and tissue-specific TFs were identified, and a TFs-based regulation network between TFs and the target genes involved in 'Phenylpropanoid biosynthesis' pathway were constructed to show several important TFs and key nodes in the regulation process. Collectively, this study not only provided an available stem transcriptome resource in B. napus, but also revealed valuable comparative transcriptome information of five tissues of B. napus for future investigation on specific processes, functions and pathways. PMID- 27708657 TI - Monte Carlo Modeling of Photon Propagation Reveals Highly Scattering Coral Tissue. AB - Corals are very efficient at using solar radiation, with photosynthetic quantum efficiencies approaching theoretical limits. Here, we investigated potential mechanisms underlying such outstanding photosynthetic performance through extracting inherent optical properties of the living coral tissue and skeleton in a massive faviid coral. Using Monte Carlo simulations developed for medical tissue optics it is shown that for the investigated faviid coral, the coral tissue was a strongly light scattering matrix with a reduced scattering coefficient of MUs' = 10 cm-1 (at 636 nm). In contrast, the scattering coefficient of the coral skeleton was MUs' = 3.4 cm-1, which facilitated the efficient propagation of light to otherwise shaded coral tissue layers, thus supporting photosynthesis in lower tissues. Our study provides a quantification of coral tissue optical properties in a massive faviid coral and suggests a novel light harvesting strategy, where tissue and skeletal optics act in concert to optimize the illumination of the photosynthesizing algal symbionts embedded within the living coral tissue. PMID- 27708658 TI - Carotenoid Derivates in Achiote (Bixa orellana) Seeds: Synthesis and Health Promoting Properties. AB - Bixa orellana (family Bixaceae) is a neotropical fast growing perennial tree of great agro-industrial value because its seeds have a high carotenoid content, mainly bixin. It has been used since pre-colonial times as a culinary colorant and spice, and for healing purposes. It is currently used as a natural pigment in the food, in pharmaceutical, and cosmetic industries, and it is commercially known as annatto. Recently, several studies have addressed the biological and medical properties of this natural pigment, both as potential source of new drugs or because its ingestion as a condiment or diet supplement may protect against several diseases. The most documented properties are anti-oxidative; but its anti cancer, hypoglucemic, antibiotic and anti-inflammatory properties are also being studied. Bixin's pathway elucidation and its regulation mechanisms are critical to improve the produce of this important carotenoid. Even though the bixin pathway has been established, the regulation of the genes involved in bixin production remains largely unknown. Our laboratory recently published B. orellana's transcriptome and we have identified most of its MEP (methyl-D erythritol 4-phosphate) and carotenoid pathway genes. Annatto is a potential source of new drugs and can be a valuable nutraceutical supplement. However, its nutritional and healing properties require further study. PMID- 27708660 TI - The Effect of Orobanche crenata Infection Severity in Faba Bean, Field Pea, and Grass Pea Productivity. AB - Broomrape weeds (Orobanche and Phelipanche spp.) are root holoparasites that feed off a wide range of important crops. Among them, Orobanche crenata attacks legumes complicating their inclusion in cropping systems along the Mediterranean area and West Asia. The detrimental effect of broomrape parasitism in crop yield can reach up to 100% depending on infection severity and the broomrape-crop association. This work provides field data of the consequences of O. crenata infection severity in three legume crops, i.e., faba bean, field pea, and grass pea. Regression functions modeled productivity losses and revealed trends in dry matter allocation in relation to infection severity. The host species differentially limits parasitic sink strength indicating different levels of broomrape tolerance at equivalent infection severities. Reductions in host aboveground biomass were observed starting at low infection severity and half maximal inhibitory performance was predicted as 4.5, 8.2, and 1.5 parasites per faba bean, field pea, and grass pea plant, respectively. Reductions in host biomass occurred in both vegetative and reproductive organs, the latter resulting more affected. The increase of resources allocated within the parasite was concomitant to reduction of host seed yield indicating that parasite growth and host reproduction compete directly for resources within a host plant. However, the parasitic sink activity does not fully explain the total host biomass reduction because combined biomass of host-parasite complex was lower than the biomass of uninfected plants. In grass pea, the seed yield was negligible at severities higher than four parasites per plant. In contrast, faba bean and field pea sustained low but significant seed production at the highest infection severity. Data on seed yield and seed number indicated that the sensitivity of field pea to O. crenata limited the production of grain yield by reducing seed number but maintaining seed size. In contrast, the size of individual parasites was not genetically determined but dependent on the host species and resource availability as a consequence of competition between parasites at increasing infection severities. PMID- 27708659 TI - Genetic Diversity, Rather than Cultivar Type, Determines Relative Grain Cd Accumulation in Hybrid Rice. AB - Cadmium (Cd) is a toxic element, and rice is known to be a leading source of dietary Cd for people who consume rice as their main caloric resource. Hybrid rice has dominated rice production in southern China and has been adopted worldwide. The characteristics of high yield heterosis of rice hybrids makes the public think intuitively that the hybrid rice accumulates more Cd in grain than do inbred cultivars. A detailed understanding of the genetic basis of grain Cd accumulation in hybrids and developing Cd-safe rice are one of the top priorities for hybrid rice breeders at present. In this study, we investigated genetic diversity and grain Cd levels in 617 elite rice hybrids collected from the middle and lower Yangtze River Valley in China and 68 inbred cultivars from around the world. We found that there are large variations in grain Cd accumulation in both the hybrids and their inbred counterparts. However, we found grain Cd levels in the rice hybrids to be similar to the levels in indica rice inbreds, suggesting that the hybrids do not accumulate more Cd than do the inbred rice cultivars. Further analysis revealed that the high heritability of Cd accumulation in the grain and the single indica population structure increases the risk of Cd over accumulation in hybrid rice. The genetic effects of Cd-related QTLs, which have been identified in related Cd-QTL mapping studies, were also determined in the hybrid rice population. Four QTLs were identified as being associated with the variation in grain Cd levels; three of these loci exhibited obvious indica japonica differentiations. Our study will provide a better understanding of grain Cd accumulations in hybrid rice, and pave the way toward effective breeding for high-yielding, low grain-Cd hybrids in the future. PMID- 27708661 TI - Moderate Genetic Diversity and Genetic Differentiation in the Relict Tree Liquidambar formosana Hance Revealed by Genic Simple Sequence Repeat Markers. AB - Chinese sweetgum (Liquidambar formosana) is a relatively fast-growing ecological pioneer species. It is widely used for multiple purposes. To assess the genetic diversity and genetic differentiation of the species, genic SSR markers were mined from transcriptome data for subsequent analysis of the genetic diversity and population structure of natural populations. A total of 10645 potential genic SSR loci were identified in 80482 unigenes. The average frequency was one SSR per 5.12 kb, and the dinucleotide unit was the most abundant motif. A total of 67 alleles were found, with a mean of 6.091 alleles per locus and a mean polymorphism information content of 0.390. Moreover, the species exhibited a relatively moderate level of genetic diversity (He = 0.399), with the highest was found in population XY (He = 0.469). At the regional level, the southwestern region displayed the highest genetic diversity (He = 0.435) and the largest number of private alleles (n = 5), which indicated that the Southwestern region may be the diversity hot spot of L. formosana. The AMOVA results showed that variation within populations (94.02%) was significantly higher than among populations (5.98%), which was in agreement with the coefficient of genetic differentiation (Fst = 0.076). According to the UPGMA analysis and principal coordinate analysis and confirmed by the assignment test, 25 populations could be divided into three groups, and there were different degrees of introgression among populations. No correlation was found between genetic distance and geographic distance (P > 0.05). These results provided further evidence that geographic isolation was not the primary factor leading to the moderate genetic differentiation of L. formosana. As most of the genetic diversity of L. formosana exists among individuals within a population, individual plant selection would be an effective way to use natural variation in genetic improvement programs. This would be helpful to not only protect the genetic resources but also attain effective management and exploit genetic resources. PMID- 27708662 TI - Comparative Analysis of miRNAs and Their Target Transcripts between a Spontaneous Late-Ripening Sweet Orange Mutant and Its Wild-Type Using Small RNA and Degradome Sequencing. AB - Fruit ripening in citrus is not well-understood at the molecular level. Knowledge of the regulatory mechanism of citrus fruit ripening at the post-transcriptional level in particular is lacking. Here, we comparatively analyzed the miRNAs and their target genes in a spontaneous late-ripening mutant, "Fengwan" sweet orange (MT) (Citrus sinensis L. Osbeck), and its wild-type counterpart ("Fengjie 72-1," WT). Using high-throughput sequencing of small RNAs and RNA degradome tags, we identified 107 known and 21 novel miRNAs, as well as 225 target genes. A total of 24 miRNAs (16 known miRNAs and 8 novel miRNAs) were shown to be differentially expressed between MT and WT. The expression pattern of several key miRNAs and their target genes during citrus fruit development and ripening stages was examined. Csi-miR156k, csi-miR159, and csi-miR166d suppressed specific transcription factors (GAMYBs, SPLs, and ATHBs) that are supposed to be important regulators involved in citrus fruit development and ripening. In the present study, miRNA-mediated silencing of target genes was found under complicated and sensitive regulation in citrus fruit. The identification of miRNAs and their target genes provide new clues for future investigation of mechanisms that regulate citrus fruit ripening. PMID- 27708663 TI - Invasive Chloroplast Population Genetics of Mikania micrantha in China: No Local Adaptation and Negative Correlation between Diversity and Geographic Distance. AB - Two fundamental questions on how invasive species are able to rapidly colonize novel habitat have emerged. One asks whether a negative correlation exists between the genetic diversity of invasive populations and their geographic distance from the origin of introduction. The other is whether selection on the chloroplast genome is important driver of adaptation to novel soil environments. Here, we addressed these questions in a study of the noxious invasive weed, Mikania micrantha, which has rapidly expanded in to southern China after being introduced to Hong Kong in 1884. Seven chloroplast simple sequence repeats (cpSSRs) were used to investigate population genetics in 28 populations of M. micrantha, which produced 39 loci. The soil compositions for these populations, including Mg abundance, were measured. The results showed that M. micrantha possessed relatively high cpSSR variation and differentiation among populations. Multiple diversity indices were quantified, and none was significantly correlated with distance from the origin of introduction. No evidence for "isolation by distance," significant spatial structure, bottlenecks, nor linkage disequilibrium was detected. We also were unable to identify loci on the chloroplast genome that exhibited patterns of differentiation that would suggest adaptive evolution in response to soil attributes. Soil Mg had only a genome-wide effect instead of being a selective factor, which highlighted the association between Mg and the successful invasion. This study characterizes the role of the chloroplast genome of M. micrantha during its recent invasion of southern China. PMID- 27708665 TI - Time Hierarchies and Model Reduction in Canonical Non-linear Models. AB - The time-scale hierarchies of a very general class of models in differential equations is analyzed. Classical methods for model reduction and time-scale analysis have been adapted to this formalism and a complementary method is proposed. A unified theoretical treatment shows how the structure of the system can be much better understood by inspection of two sets of singular values: one related to the stoichiometric structure of the system and another to its kinetics. The methods are exemplified first through a toy model, then a large synthetic network and finally with numeric simulations of three classical benchmark models of real biological systems. PMID- 27708664 TI - Single-Cell Transcriptomics Bioinformatics and Computational Challenges. AB - The emerging single-cell RNA-Seq (scRNA-Seq) technology holds the promise to revolutionize our understanding of diseases and associated biological processes at an unprecedented resolution. It opens the door to reveal intercellular heterogeneity and has been employed to a variety of applications, ranging from characterizing cancer cells subpopulations to elucidating tumor resistance mechanisms. Parallel to improving experimental protocols to deal with technological issues, deriving new analytical methods to interpret the complexity in scRNA-Seq data is just as challenging. Here, we review current state-of-the art bioinformatics tools and methods for scRNA-Seq analysis, as well as addressing some critical analytical challenges that the field faces. PMID- 27708666 TI - Co-expression Pattern Analysis of miR-17-92 Target Genes in Chronic Myelogenous Leukemia. AB - MicroRNAs (miRNAs) are post-transcriptional regulators that regulate gene expression by binding to the 3' untranslated region of target mRNAs. Mature miRNAs transcribed from the miR-17-92 cluster have an oncogenic activity, which are overexpressed in chronic-phase chronic myelogenous leukemia (CML) patients compared with normal individuals. Besides, the tyrosine kinase activity of BCR ABL oncoprotein from the Philadelphia chromosome in CML can affect this miRNA cluster. Genes with similar mRNA expression profiles are likely to be regulated by the same regulators. We hypothesize that target genes regulated by the same miRNA are co-expressed. In this study, we aim to explore the difference in the co expression patterns of those genes potentially regulated by miR-17-92 cluster between the normal and the CML groups. We applied a statistical method for gene pair classification by identifying a disease-specific cutoff point that classified the co-expressed gene pairs into strong and weak co-expression classes. The method effectively identified the differences in the co-expression patterns from the overall structure. Functional annotation for co-expressed gene pairs showed that genes involved in the metabolism processes were more likely to be co-expressed in the normal group compared to the CML group. Our method can identify the co-expression pattern difference from the overall structure between two different distributions using the distribution-based statistical method. Functional annotation further provides the biological support. The co-expression pattern in the normal group is regarded as the inter-gene linkages, which represents the healthy pathological balance. Dysregulation of metabolism may be related to CML pathology. Our findings will provide useful information for investigating the novel CML mechanism and treatment.

PMID- 27708669 TI - Genetic susceptibility to allergic bronchopulmonary aspergillosis in asthma: a genetic association study. AB - BACKGROUND: In patients with asthma, the fungus Aspergillus fumigatus can cause allergic bronchopulmonary aspergillosis (ABPA). Familial ABPA is reported, and some genetic factors have been associated with the disease, however, these are small studies (n <= 38) and do not explain all cases of ABPA. METHODS: We analysed SNPs in 95 ABPA patients, comparing frequencies to 152 atopic asthmatic and 279 healthy controls. Twenty two genes were selected from literature, and 195 tagging SNPs were analysed for genetic association with ABPA using logistic regression corrected for multiple testing. We also analysed monocyte-derived macrophage gene expression before and during co-culture with A. fumigatus. RESULTS: Seventeen ABPA-associated SNPs (ABPA v Atopic asthma) were identified. Three remained significant after correction for multiple testing; IL13 rs20541, IL4R rs3024656, TLR3 rs1879026. We also identified minor differences in macrophage gene expression responses in the ABPA group compared to the control groups. CONCLUSIONS: Multiple SNPs are now associated with ABPA. Some are novel associations. These associations implicate cytokine pathways and receptors in the aberrant response to A. fumigatus and susceptibility to ABPA, providing insights into the pathogenesis of ABPA and/or its complications. We hope these results will lead to increased understanding and improved treatment and diagnostics for ABPA. PMID- 27708671 TI - Pharmacists without Borders Canada: An update. PMID- 27708667 TI - Admixture Mapping of African-American Women in the AMBER Consortium Identifies New Loci for Breast Cancer and Estrogen-Receptor Subtypes. AB - Recent genetic admixture coupled with striking differences in incidence of estrogen receptor (ER) breast cancer subtypes, as well as severity, between women of African and European ancestry, provides an excellent rationale for performing admixture mapping in African American women with breast cancer risk. We performed the largest breast cancer admixture mapping study with in African American women to identify novel genomic regions associated with the disease. We conducted a genome-wide admixture scan using 2,624 autosomal ancestry informative markers (AIMs) in 3,629 breast cancer cases (including 1,968 ER-positive, 1093 ER negative, and 601 triple-negative) and 4,658 controls from the African American Breast Cancer Epidemiology and Risk (AMBER) Consortium, a collaborative study of four large geographically different epidemiological studies of breast cancer in African American women. We used an independent case-control study to test for SNP association in regions with genome-wide significant admixture signals. We found two novel genome-wide significant regions of excess African ancestry, 4p16.1 and 17q25.1, associated with ER-positive breast cancer. Two regions known to harbor breast cancer variants, 10q26 and 11q13, were also identified with excess of African ancestry. Fine-mapping of the identified genome-wide significant regions suggests the presence of significant genetic associations with ER-positive breast cancer in 4p16.1 and 11q13. In summary, we identified three novel genomic regions associated with breast cancer risk by ER status, suggesting that additional previously unidentified variants may contribute to the racial differences in breast cancer risk in the African American population.

AB - As the Canadian population continues to age, the incidence of cancer is on the rise. To help alleviate the burden malignancy imposes on our health care system, a shift toward early cancer detection is necessary. Pharmacists are well positioned and willing to assume a more active role in cancer surveillance. Patients are receptive to pharmacist involvement and seem to prefer a convenient community pharmacy-based location for screening programs. The community pharmacist's current and potential role in cancer screening and prevention is summarized in this article. A review of screening recommendations and a discussion of opportunities will hopefully inspire pharmacists to consider incorporating malignancy screening initiatives into their practice. PMID- 27708674 TI - A randomized trial of a community-based approach to dyslipidemia management: Pharmacist prescribing to achieve cholesterol targets (RxACT Study). AB - BACKGROUND: Dyslipidemia is an important risk factor for cardiovascular disease but is suboptimally managed. Pharmacists are accessible primary care professionals and with expanded scopes of practice (including prescribing), could identify and manage patients with dyslipidemia. We sought to evaluate the effect of pharmacist prescribing of dyslipidemia medications on the proportion of participants achieving target LDL-cholesterol (LDL-c) levels. METHODS: We conducted a randomized controlled trial in 14 community pharmacies in Alberta, Canada. We enrolled adults with uncontrolled dyslipidemia as defined by the 2009 Canadian Dyslipidemia Guidelines. Intervention was pharmacist-directed dyslipidemia care, including assessment of cardiovascular risk, review of LDL-c, prescribing of medications, health behaviour interventions and follow-up every 6 weeks for 6 months. Usual care patients received their lipid results and a pamphlet on cardiovascular disease and usual care from their physician and pharmacist. Primary outcome was the proportion of participants achieving their target LDL-c (<2 mmol/L or >=50% reduction) at 6 months between groups. RESULTS: We enrolled 99 patients with a mean (SD) age of 63 (13) years, 49% male and baseline LDL-c of 3.37 mmol/L (0.98). Proportion of patients achieving LDL-c target was 43% intervention versus 18% control (p = 0.007). Adjusted odds of achieving target LDL-c were 3.3 times higher for the intervention group (p = 0.031), who also achieved greater reduction in LDL-c (1.12 mmol/L, SE = 0.112) versus control (0.42 mmol/L, SE = 0.109), for an adjusted mean difference of 0.546 mmol/L (SE = 0.157), p < 0.001. CONCLUSION: Pharmacist prescribing resulted in >3-fold more patients achieving target LDL-c levels. This could have major public health implications. PMID- 27708675 TI - Uptake of the MedsCheck annual medication review service in Ontario community pharmacies between 2007 and 2013. AB - BACKGROUND: MedsCheck Annual (MCA) is an Ontario government-funded medication review service for individuals taking 3 or more prescription medications for chronic conditions. METHODS: This cohort study analyzed linked administrative claims data from April 1, 2007, to March 31, 2013. Trends in MCA claims and recipient characteristics were examined. RESULTS: A total of 1,498,440 Ontarians (55% seniors, 55% female) received an MCA. One-third (36%) had 2 or more MCAs within 6 years. Service provision increased over time, with a sharper increase from 2010 onward. Almost half of Ontario pharmacies made at least 1 MCA claim in the first month of the program. Hypertension, respiratory disease, diabetes, psychiatric conditions and arthritis were common comorbidities. Recipients older than 65 years were most commonly dispensed an antihypertensive and/or antihyperlipidemic drug in the prior year and received an average of 11 unique prescription medications. Thirty-eight percent of recipients visited an emergency department or were hospitalized in the year prior to their first MCA. DISCUSSION: Over the first 6 years of the program, approximately 1 in 9 Ontarians received an MCA. There was rapid and widespread uptake of the service. Common chronic conditions were well represented among MCA recipients. Older MCA recipients had less emergency department use compared with population-based estimates. CONCLUSIONS: Medication reviews increased over time; however, the number of persons receiving the service more than once was low. Service delivery was generally consistent with program eligibility; however, there are some findings possibly consistent with delivery to less complex patients. PMID- 27708676 TI - Quit rates at 6 months in a pharmacist-led smoking cessation service in Malaysia. AB - BACKGROUND: Smoking cessation clinics have been established in Malaysia since 2004, but wide variations in success rates have been observed. This study aimed to evaluate the proposed pharmacist-led Integrated Quit Smoking Service (IQSS) in Sabah, Malaysia, and identify factors associated with successful smoking cessation. METHODS: Data from 176 participants were collected from one of the quit-smoking centres in Sabah, Malaysia. Pharmacists, doctors and nurses were involved throughout the study. Any health care provider can refer patients for smoking cessation, and free pharmacotherapy and counselling was provided during the cessation period for up to 3 months. Information on demographic characteristics, smoking behaviours, follow-up and pharmacotherapy were collected. The main outcome measure was the abstinence from smoking, which was verified through carbon monoxide in expired air during the 6-month follow-up. RESULTS: A 42.6% success rate was achieved in IQSS. Smoking behaviour such as lower cigarette intake and lower Fagerstrom score were identified as factors associated with success. On top of that, a longer duration of follow-up and more frequent visits were significantly associated with success in quitting smoking. CONCLUSION: Collaboration among health care practitioners should be the main focus, and we need a combination of proven effective modalities in order to create an ideal smoking cessation module. PMID- 27708677 TI - Pharmacoeconomic comparison of aripiprazole once-monthly and paliperidone palmitate from a head-to-head clinical trial in schizophrenia: a US analysis. AB - Schizophrenia presents a substantial clinical and economic burden to the health care system. In QUAlity of LIfe with AbiliFY Maintena (QUALIFY), a randomized head-to-head study of aripiprazole once-monthly 400 mg (AOM 400) compared with paliperidone palmitate (PP; 78-234 mg/mo), AOM 400 demonstrated greater improvement in health-related quality of life and functioning in patients with stable schizophrenia. The present analysis used health economics assessment data collected during the QUALIFY study to determine the direct medical and pharmacy costs and the cost-effectiveness associated with each treatment over 6 months. Compared with those receiving PP, patients receiving AOM 400 incurred significantly lower direct total costs ($8908+/-186 vs $9675+/-190, p=0.005) and treatment costs ($7967+/-113 vs $8706+/-116, p<0.001). Effectiveness results in the subset of patients included in the cost analyses were similar to the overall population: mean (95% CI) improvement in Heinrichs-Carpenter Quality of Life Scale total score was greater with AOM 400 (5.97 [3.87; 8.08]) compared with PP (2.85 [0.56; 5.08]). Likewise, Clinical Global Impression-Severity improved more in the AOM 400 group (-0.59 [-0.71; -0.47]) compared with PP group (-0.37 [-0.46; -0.27]). Therefore, the analysis of data from stabilized patients with schizophrenia in the QUALIFY study indicated that AOM 400 is associated with lower health-care costs and greater effectiveness compared with PP and thus represents the economically dominant strategy. PMID- 27708679 TI - Development of foraging skills in two orangutan populations: needing to learn or needing to grow? AB - BACKGROUND: Orangutans have one of the slowest-paced life histories of all mammals. Whereas life-history theory suggests that the time to reach adulthood is constrained by the time needed to reach adult body size, the needing-to-learn hypothesis instead suggests that it is limited by the time needed to acquire adult-level skills. To test between these two hypotheses, we compared the development of foraging skills and growth trajectories of immature wild orangutans in two populations: at Tuanan (Pongo pygmaeus wurmbii), Borneo, and Suaq Balimbing (Pongo abelii), Sumatra. We collected behavioral data on diet repertoire, feeding rates and ranging competence during focal follows, and estimated growth through non-invasive laser photogrammetry. RESULTS: We found that adult-like diet repertoires are attained around the age of weaning and that female immatures increase their repertoire size faster than their male peers. Adult-level feeding rates of easy techniques are reached just after weaning, but several years later for more difficult techniques, albeit always before adulthood (i.e. age at first reproduction). Independent immatures had faster feeding rates for easy to process items than their mothers, with male immatures achieving faster feeding rates earlier in development relative to females. Sumatran immatures reach adult-level feeding rates 2-3 years later than their Bornean peers, in line with their higher dietary complexity and later weaning. The range use competence of independently ranging and weaned immatures is similar to that of adult females. Body size measurements showed, immatures grow until female age of first reproduction. CONCLUSIONS: In conclusion, unlike in humans, orangutan foraging skills are in place prior to reproduction. Growth trajectories suggest that energetic constraints, rather than skills, best explain the length of immaturity. However, skill competence for dietary independence is reached later where the adult niche is more complex, which is consistent with the relatively later weaning age with increasing brain size found generally in primates, and apes in particular. PMID- 27708680 TI - The cephalopod arm crown: appendage formation and differentiation in the Hawaiian bobtail squid Euprymna scolopes. AB - BACKGROUND: Cephalopods are a highly derived class of molluscs that adapted their body plan to a more active and predatory lifestyle. One intriguing adaptation is the modification of the ventral foot to form a bilaterally symmetric arm crown, which constitutes a true morphological novelty in evolution. In addition, this structure shows many diversifications within the class of cephalopods and therefore offers an interesting opportunity to study the molecular underpinnings of the emergence of phenotypic novelties and their diversification. Here we use the sepiolid Euprymna scolopes as a model to study the formation and differentiation of the decabrachian arm crown, which consists of four pairs of sessile arms and one pair of retractile tentacles. We provide a detailed description of arm crown formation in order to understand the basic morphology and the developmental dynamics of this structure. RESULTS: We show that the morphological formation of the cephalopod appendages occurs during distinct phases, including outgrowth, elongation, and tissue differentiation. Early outgrowth is characterized by uniform cell proliferation, while the elongation of the appendages initiates tissue differentiation. The latter progresses in a gradient from proximal to distal, whereas cell proliferation becomes restricted to the distal-most end of the arm. Differences in the formation of arms and tentacles exist, with the tentacles showing an expedite growth rate and higher complexity at younger stages. CONCLUSION: The early outgrowth and differentiation of the E. scolopes arm crown shows similarities to the related, yet derived cephalopod Octopus vulgaris. Parallels in the growth and differentiation of appendages seem to exist throughout the animal kingdom, raising the question of whether these similarities reflect a recruitment of similar molecular patterning pathways. PMID- 27708678 TI - Current trends and intricacies in the management of HIV-associated pulmonary tuberculosis. AB - Human immunodeficiency virus (HIV) epidemic has undoubtedly increased the incidence of tuberculosis (TB) globally, posing a formidable global health challenge affecting 1.2 million cases. Pulmonary TB assumes utmost significance in the programmatic perspective as it is readily transmissible as well as easily diagnosable. HIV complicates every aspect of pulmonary tuberculosis from diagnosis to treatment, demanding a different approach to effectively tackle both the diseases. In order to control these converging epidemics, it is important to diagnose early, initiate appropriate therapy for both infections, prevent transmission and administer preventive therapy. Liquid culture methods and nucleic acid amplification tests for TB confirmation have replaced conventional solid media, enabling quicker and simultaneous detection of mycobacterium and its drug sensitivity profile Unique problems posed by the syndemic include Acquired rifampicin resistance, drug-drug interactions, malabsorption of drugs and immune reconstitution inflammatory syndrome or paradoxical reaction that complicate dual and concomitant therapy. While the antiretroviral therapy armamentarium is constantly reinforced by discovery of newer and safer drugs every year, only a few drugs for anti tuberculosis treatment have successfully emerged. These include bedaquiline, delamanid and pretomanid which have entered phase III B trials and are also available through conditional access national programmes. The current guidelines by WHO to start Antiretroviral therapy irrespective of CD4+ cell count based on benefits cited by recent trials could go a long way in preventing various complications caused by the deadly duo. This review provides a consolidated gist of the advancements, concepts and updates that have emerged in the management of HIV-associated pulmonary TB for maximizing efficacy, offering latest solutions for tackling drug-drug interactions and remedial measures for immune reconstitution inflammatory syndrome. PMID- 27708681 TI - Comparative localization of serotonin-like immunoreactive cells in Thaliacea informs tunicate phylogeny. AB - BACKGROUND: Thaliaceans is one of the understudied classes of the phylum Tunicata. In particular, their phylogenetic relationships remain an issue of debate. The overall pattern of serotonin (5-HT) distribution is an excellent biochemical trait to interpret internal relationships at order level. In the experiments reported here we compared serotonin-like immunoreactivity at different life cycle stages of two salpid, one doliolid, and one pyrosomatid species. This multi-species comparison provides new neuroanatomical data for better resolving the phylogeny of the class Thaliacea. RESULTS: Adults of all four examined thaliacean species exhibited serotonin-like immunoreactivity in neuronal and non-neuronal cell types, whose anatomical position with respect to the nervous system is consistently identifiable due to alpha-tubulin immunoreactivity. The results indicate an extensive pattern that is consistent with the presence of serotonin in cell bodies of variable morphology and position, with some variation within and among orders. Serotonin-like immunoreactivity was not found in immature forms such as blastozooids (Salpida), tadpole larvae (Doliolida) and young zooids (Pyrosomatida). CONCLUSIONS: Comparative anatomy of serotonin-like immunoreactivity in all three thaliacean clades has not been reported previously. These results are discussed with regard to studies of serotonin-like immunoreactivity in adult ascidians. Lack of serotonin-like immunoreactivity in the endostyle of Salpida and Doliolida compared to Pyrosomella verticillata might be the result of secondary loss of serotonin control over ciliary beating and mucus secretion. These data, when combined with other plesiomorphic characters, support the hypothesis that Pyrosomatida is basal to these clades within Phlebobranchiata and that Salpida and Doliolida constitute sister-groups. PMID- 27708682 TI - Hepatic adaptations to maintain metabolic homeostasis in response to fasting and refeeding in mice. AB - BACKGROUND: The increased incidence of obesity and associated metabolic diseases has driven research focused on genetically or pharmacologically alleviating metabolic dysfunction. These studies employ a range of fasting-refeeding models including 4-24 h fasts, "overnight" fasts, or meal feeding. Still, we lack literature that describes the physiologically relevant adaptations that accompany changes in the duration of fasting and re-feeding. Since the liver is central to whole body metabolic homeostasis, we investigated the timing of the fast-induced shift toward glycogenolysis, gluconeogenesis, and ketogenesis and the meal induced switch toward glycogenesis and away from ketogenesis. METHODS: Twelve to fourteen week old male C57BL/6J mice were fasted for 0, 4, 8, 12, or 16 h and sacrificed 4 h after lights on. In a second study, designed to understand the response to a meal, we gave fasted mice access to feed for 1 or 2 h before sacrifice. We analyzed the data using mixed model analysis of variance. RESULTS: Fasting initiated robust metabolic shifts, evidenced by changes in serum glucose, non-esterified fatty acids (NEFAs), triacylglycerol, and beta-OH butyrate, as well as, liver triacylglycerol, non-esterified fatty acid, and glycogen content. Glycogenolysis is the primary source to maintain serum glucose during the first 8 h of fasting, while de novo gluconeogenesis is the primary source thereafter. The increase in serum beta-OH butyrate results from increased enzymatic capacity for fatty acid flux through beta-oxidation and shunting of acetyl-CoA toward ketone body synthesis (increased CPT1 (Carnitine Palmitoyltransferase 1) and HMGCS2 (3 Hydroxy-3-Methylglutaryl-CoA Synthase 2) expression, respectively). In opposition to the relatively slow metabolic adaptation to fasting, feeding of a meal results in rapid metabolic changes including full depression of serum beta-OH butyrate and NEFAs within an hour. CONCLUSIONS: Herein, we provide a detailed description of timing of the metabolic adaptations in response to fasting and re-feeding to inform study design in experiments of metabolic homeostasis. Since fasting and obesity are both characterized by elevated adipose tissue lipolysis, hepatic lipid accumulation, ketogenesis, and gluconeogenesis, understanding the drivers behind the metabolic shift from the fasted to the fed state may provide targets to limit aberrant gluconeogenesis and ketogenesis in obesity. PMID- 27708684 TI - The impact of protein quality on the promotion of resistance exercise-induced changes in muscle mass. AB - Protein supplementation during resistance exercise training augments hypertrophic gains. Protein ingestion and the resultant hyperaminoacidemia provides the building blocks (indispensable amino acids - IAA) for, and also triggers an increase in, muscle protein synthesis (MPS), suppression of muscle protein breakdown (MPB), and net positive protein balance (i.e., MPS > MPB). The key amino acid triggering the rise in MPS is leucine, which stimulates the mechanistic target of rapamycin complex-1, a key signalling protein, and triggers a rise in MPS. As such, ingested proteins with a high leucine content would be advantageous in triggering a rise in MPS. Thus, protein quality (reflected in IAA content and protein digestibility) has an impact on changes in MPS and could ultimately affect skeletal muscle mass. Protein quality has been measured by the protein digestibility-corrected amino acid score (PDCAAS); however, the digestible indispensable amino acid score (DIAAS) has been recommended as a better method for protein quality scoring. Under DIAAS there is the recognition that amino acids are individual nutrients and that protein quality is contingent on IAA content and ileal (as opposed to fecal) digestibility. Differences in protein quality may have important ramifications for exercise-induced changes in muscle mass gains made with resistance exercise as well as muscle remodelling. Thus, the purpose of this review is a critical appraisal of studies examining the effects of protein quality in supplementation on changes in muscle mass and strength as well as body composition during resistance training. PMID- 27708683 TI - Microarray analysis of gene expression in liver, adipose tissue and skeletal muscle in response to chronic dietary administration of NDGA to high-fructose fed dyslipidemic rats. AB - Nordihydroguaiaretic acid (NDGA), the main metabolite of Creosote Bush, has been shown to have profound effects on the core components of metabolic syndrome, including lowering of blood glucose, free fatty acids and triglyceride levels, attenuating elevated blood pressure in several rodent models of dyslipidemia, and improving body weight, insulin resistance, diabetes and hypertension. In the present study, a high-fructose diet fed rat model of hypertriglyceridemia, dyslipidemia, insulin resistance and hepatic steatosis was employed to investigate the global transcriptional changes in the lipid metabolizing pathways in three insulin sensitive tissues: liver, skeletal muscle and adipose tissue in response to chronic dietary administration of NDGA. Sprague-Dawley male rats (SD) were fed a chow (control) diet, high-fructose diet (HFrD) or HFrD supplemented with NDGA (2.5 g/kg diet) for eight weeks. Dietary administration of NDGA decreased plasma levels of TG, glucose, and insulin, and attenuated hepatic TG accumulation. DNA microarray expression profiling indicated that dietary administration of NDGA upregulated the expression of certain genes involved in fatty acid oxidation and their transcription regulator, PPARalpha, decreased the expression of a number of lipogenic genes and relevant transcription factors, and differentially impacted the genes of fatty acid transporters, acetyl CoA synthetases, elongases, fatty acid desaturases and lipid clearance proteins in liver, skeletal muscle and adipose tissues. These findings suggest that NDGA ameliorates hypertriglyceridemia and steatosis primarily by inhibiting lipogenesis and enhancing fatty acid catabolism in three major insulin responsive tissues by altering the expression of key enzyme genes and transcription factors involved in de novo lipogenesis and fatty acid oxidation. PMID- 27708687 TI - Unveiling consumer's privacy paradox behaviour in an economic exchange. AB - Privacy paradox is of great interest to IS researchers and firms gathering personal information. It has been studied from social, behavioural, and economic perspectives independently. However, prior research has not examined the degrees of influence these perspectives contribute to the privacy paradox problem. We combine both economic and behavioural perspectives in our study of the privacy paradox with a price valuation of personal information through an economic experiment combined with a behavioural study on privacy paradox. Our goal is to reveal more insights on the privacy paradox through economic valuation on personal information. Results indicate that general privacy concerns or individual disclosure concerns do not have a significant influence on the price valuation of personal information. Instead, prior disclosure behaviour in specific scenario, like with healthcare providers or social networks, is a better indicator of consumer price valuations. PMID- 27708686 TI - A 13-Weeks Mindfulness Based Pain Management Program Improves Psychological Distress in Patients with Chronic Pain Compared with Waiting List Controls. AB - BACKGROUND: Eradication of pain is seldom an option in chronic pain management. Hence, mindfulness meditation has become popular in pain management. OBJECTIVE: This pilot study compared the effect of a 13-weeks cognitive behavioural therapy program with integrated mindfulness meditation (CBTm) in patients with chronic non-malignant pain with a control condition. It was hypothesised that the CBTm program would reduce pain intensity and psychological distress compared to the control condition and that level of mindfulness and acceptance both would be associated with the reduction in pain intensity and psychological distress. METHODS: A case-control design was used and data were collected from a convenience sample of 70 patients with chronic non-malignant pain. Fifty patients were consecutively recruited to the CBTm intervention and 20 patients matched waiting list controls. Assessments of clinical pain and psychological distress were performed in both groups at baseline and after 13 weeks. RESULTS: The CBTm program reduced depression, anxiety and pain-catastrophizing compared with the control group. Increased level of mindfulness and acceptance were associated with change in psychological distress with the exception of depression, which was only associated with change in level of mindfulness. Surprisingly, changes in level of mindfulness did not correlate with changes in acceptance. CONCLUSIONS: The results indicate that different mechanisms are targeted with cognitive behavioural therapy and mindfulness. The finding that changes in level of mindfulness did not correlate with changes in acceptance may indicate that acceptance is not a strict prerequisite for coping with pain related distress. PMID- 27708685 TI - Animal models of metabolic syndrome: a review. AB - Metabolic syndrome (MetS) consists of several medical conditions that collectively predict the risk for cardiovascular disease better than the sum of individual conditions. The risk of developing MetS in human depends on synergy of both genetic and environmental factors. Being a multifactorial condition with alarming rate of prevalence nowadays, establishment of appropriate experimental animal models mimicking the disease state in humans is crucial in order to solve the difficulties in evaluating the pathophysiology of MetS in human. This review aims to summarize the underlying mechanisms involved in the pathophysiology of dietary, genetic, and pharmacological models of MetS. Furthermore, we will discuss the usefulness, suitability, pros and cons of these animal models. Even though numerous animal models of MetS have been established, further investigations on the invention of new animal model and clarification of plausible mechanisms are still necessary to confer a better understanding to researchers on the selection of animal models for their studies. PMID- 27708688 TI - The CSL proteins, versatile transcription factors and context dependent corepressors of the notch signaling pathway. AB - The Notch signaling pathway is a reiteratively used cell to cell communication pathway that triggers pleiotropic effects. The correct regulation of the pathway permits the efficient regulation of genes involved in cell fate decision throughout development. This activity relies notably on the CSL proteins, (an acronym for CBF-1/RBPJ-kappa in Homo sapiens/Mus musculus respectively, Suppressor of Hairless in Drosophila melanogaster, Lag-1 in Caenorhabditis elegans) which is the unique transcription factor and DNA binding protein involved in this pathway. The CSL proteins have the capacity to recruit activation or repression complexes according to the cellular context. The aim of this review is to describe the different co-repressor proteins that interact directly with CSL proteins to form repression complexes thereby regulating the Notch signaling pathway in animal cells to give insights into the paralogous evolution of these co-repressors in higher eumetazoans and their subsequent effects at developmental processes. PMID- 27708689 TI - An efficient algorithm for protein structure comparison using elastic shape analysis. AB - BACKGROUND: Protein structure comparison play important role in in silico functional prediction of a new protein. It is also used for understanding the evolutionary relationships among proteins. A variety of methods have been proposed in literature for comparing protein structures but they have their own limitations in terms of accuracy and complexity with respect to computational time and space. There is a need to improve the computational complexity in comparison/alignment of proteins through incorporation of important biological and structural properties in the existing techniques. RESULTS: An efficient algorithm has been developed for comparing protein structures using elastic shape analysis in which the sequence of 3D coordinates atoms of protein structures supplemented by additional auxiliary information from side-chain properties are incorporated. The protein structure is represented by a special function called square-root velocity function. Furthermore, singular value decomposition and dynamic programming have been employed for optimal rotation and optimal matching of the proteins, respectively. Also, geodesic distance has been calculated and used as the dissimilarity score between two protein structures. The performance of the developed algorithm is tested and found to be more efficient, i.e., running time reduced by 80-90 % without compromising accuracy of comparison when compared with the existing methods. Source codes for different functions have been developed in R. Also, user friendly web-based application called ProtSComp has been developed using above algorithm for comparing protein 3D structures and is accessible free. CONCLUSIONS: The methodology and algorithm developed in this study is taking considerably less computational time without loss of accuracy (Table 2). The proposed algorithm is considering different criteria of representing protein structures using 3D coordinates of atoms and inclusion of residue wise molecular properties as auxiliary information. PMID- 27708691 TI - Authentication of Acori Tatarinowii Rhizoma (Shi Chang Pu) and its adulterants by morphological distinction, chemical composition and ITS sequencing. AB - BACKGROUND: Acori Tatarinowii Rhizoma (ATR; rhizome of Acorus tatarinowii Schott) (Shi Chang Pu) is widely used in Chinese medicine (CM) to resuscitate, calm the mind, resolve shi (dampness) and harmonize the wei (stomach). Seven different species have been identified as belonging to the genus Acorus, all of which can be found in China. However, it can be difficult to distinguish the different species of Acorus because of their morphological similarities. The aim of this study was to authenticate Acorus species using macroscopic and microscopic techniques, chemical analysis and DNA authentication and to compare the resolution power and reliability of these different methods. METHODS: Four batches of ATR, Acori Graminei Rhizoma (AGR), Acori Calami Rhizoma (ACR) and Anemones Altaicae Rhizoma (AAR) (totaling 16 samples) were collected from Hong Kong and mainland China. The major characteristic features of these Acorus species were identified by macroscopic and microscopic examination. The identified samples were also analyzed by UHPLC analysis. Principal component analysis (PCA) and hierarchal clustering analysis (HCA) on UHPLC results were used to differentiate between the samples. An internal transcribed spacer (ITS) was selected as a molecular probe and a modified DNA extraction method was developed to obtain trace amounts of DNA from the different Acorus species. All extracted DNA sequences were edited by Bioedit and aligned with the ClustalW. And the sequence distances were calculated using the Maximum Parsimony method. RESULTS: Macroscopic and microscopic analyses allowed for AAR to be readily distinguished from ATR, AGR and ACR. However, it was difficult to distinguish between ATR, AGR and ACR because of their similar morphological features. Chemical profiling revealed that alpha- and beta-asarone were only found in the ATR, AGR and ACR samples, but not in the AAR samples. Furthermore, PCA and HCA allowed for the differentiation of these three species based on their asarone contents. Morphological authentication and chemical profiling allowed for the partial differentiation of ATR, AGR ACR and AAR. DNA analysis was the only method capable of accurately differentiating between all four species. CONCLUSION: DNA authentication exhibited higher resolution power and reliability than conventional morphological identification and UHPLC in differentiating between different Acorus species. PMID- 27708690 TI - Validity of predictive factors of acute complicated appendicitis. AB - BACKGROUND: Our previous retrospective study revealed the three preoperative predictors of complicated appendicitis (perforated or gangrenous appendicitis), which are body temperature >=37.4 degrees C, C-reactive protein >=4.7 mg/dl, and fluid collection surrounding the appendix on computed tomography. We reported here an additional prospective study to verify our ability to predict complicated appendicitis using the three preoperative predictors and thus facilitate better informed decisions regarding emergency surgery during night or holiday shifts. METHODS: We prospectively evaluated 116 adult patients who underwent surgery for acute appendicitis from January 2013 to October 2014. Ninety patients with one or more predictive factors of complicated appendicitis underwent immediate surgery regardless of the time of patient's presentation. Twenty-six patients had no predictive factors and thus were suspected to have uncomplicated appendicitis. Of the 26 patients, 14 who presented to our hospital during office hours underwent immediate surgery. The other 12 patients who presented to our hospital at night or on a holiday underwent short, in-hospital delayed surgery during office hours. RESULTS: All patients with no predictive factors had uncomplicated appendicitis, whereas 37 %, 81 %, and 100 % of patients with one, two, or all three factors, respectively, were diagnosed with complicated appendicitis. The emergency operation rate decreased from 83 % before to 58 % after adopting this scoring system, but no significant differences in postoperative complication rates and hospitalization periods were observed. CONCLUSIONS: The above-mentioned preoperative factors predictive of complicated appendicitis preoperatively are useful for emergency surgical decisions and reduce the burdens on surgeons and medical staff. PMID- 27708694 TI - Full component analysis of Tianma-Gouteng-Yin. AB - BACKGROUND: Tianma-Gouteng-Yin (TGY), which is common Chinese medicine formulation consisting of 11 different herbs and being used in China for the treatment of Parkinson's disease, inflammatory conditions and cardiovascular diseases, was selected for full component analysis. The aim of this study was to quantitatively analyze the chemical profiles of ten commercial TGY samples and one sample produced in our laboratory. METHODS: Ultra-high performance liquid chromatography (UHPLC) coupled with quadrupole-tandem time-of-flight mass spectrometry (Q-TOF-MS) was used to analyze the non-saccharide small molecule components of the different TGY samples. The established method was validated in terms of its linearity, sensitivity, precision, accuracy and stability. High performance liquid chromatography coupled with evaporative light scattering detection (HPLC-ELSD) was also used to quantify three major saccharides (fructose, glucose and sucrose). RESULTS: The relative standard deviations for the precision, repeatability and stability of these compounds were less than 5 %, while the accuracy of the method was 95-105 %. Twenty-eight of the compounds found in TGY were successfully identified, with 20 being quantified. The macromolecules present in these samples were also identified using an ethanol precipitation method, representing 294.68-696.64 mg/g of the total material depending on the batch. Notably, the components identified using this method represented up to 78 % of the total weight of the TGY samples. CONCLUSIONS: The developed UHPLC/Q-TOF-MS and HPLC-ELSD methods successfully identified 28 of the complex compounds found in TGY. PMID- 27708692 TI - In silico profiling for secondary metabolites from Lepidium meyenii (maca) by the pharmacophore and ligand-shape-based joint approach. AB - BACKGROUND: Lepidium meyenii Walpers (maca) is an herb known as a traditional nutritional supplement and widely used in Peru, North America, and Europe to enhance human fertility and treat osteoporosis. The secondary metabolites of maca, namely, maca alkaloids, macaenes, and macamides, are bioactive compounds, but their targets are undefined. METHODS: The pharmacophore-based PharmaDB targets database screening joint the ligand shape similarity-based WEGA validation approach is proposed to predict the targets of these unique constituents and was performed using Discovery Studio 4.5 and PharmaDB. A compounds-targets-diseases network was established using Cytoscape 3.2. These suitable targets and their genes were calculated and analyzed using ingenuity pathway analysis and GeneMANIA. RESULTS: Certain targets were identified in osteoporosis (8 targets), prostate cancer (9 targets), and kidney diseases (11 targets). This was the first study to identify the targets of these bioactive compounds in maca for cardiovascular diseases (29 targets). The compound with the most targets (46) was an amide alkaloid (MA-24). CONCLUSION: In silico target fishing identified maca's traditional effects on treatment and prevention of osteoporosis, prostate cancer, and kidney diseases, and its potential function of treating cardiovascular diseases, as the most important of this herb's possible activities. PMID- 27708695 TI - A questionnaire survey regarding the support needed by Yogo teachers to take care of students suspected of having eating disorders (second report). AB - BACKGROUND: The lowering of the age of onset and chronicity have been key problems related to eating disorders (EDs). As the proportion of teens in the estimated onset ages has increased, it has become important to detect students with EDs and to clarify how they can be supported. Though epidemiological surveys of Yogo teachers (school nurse/health science teachers) have been conducted to inquire about the number of such students, none of these were done according to ED type based on DSM-5. Thus, we conducted a wide area survey in Japan with the goal of proposing a better framework of support for Yogo teachers in their efforts to care for students with EDs. METHODS: A questionnaire survey organized by ED type (based on DSM-5) was administered to Yogo teachers working at elementary/junior high/senior high/special needs schools in four prefectures of Japan in 2015, and 1,886 responses were obtained. Based on the results, the encounter rates (the proportion of Yogo teachers who had encountered a student with an ED) were calculated, and factors that could affect the rates were examined by logistic regression analysis. RESULTS: The order of the encounter rates of the ED types was as follows: Anorexia Nervosa (AN) > Bulimia Nervosa (BN) > Avoidant/Restrictive Food Intake Disorder (ARFID) > Binge Eating Disorder (BED) > Others. The factors significantly affecting the rates were "location, school type, number of students, experience years, and AN knowledge" for AN, "school type, experience years, and BN knowledge" for BN, "school type, experience years, and BED knowledge" for BED, "location, experience years, and ARFID knowledge" for ARFID, and "school type, experience years, and Others knowledge" for Others. CONCLUSIONS: Because the encounter rate of AN was the highest, providing support for AN would be the most effective. Moreover, one factor that affected the encounter rate of all ED types was ED knowledge. In addition to this, senior high schools had the highest encounter rates for AN, BN and BED, and special needs schools had the highest rates for Others. These findings imply that, in order to detect and support ED students at an early stage, it is necessary to offer knowledge of the most prevalent ED types to Yogo teachers at the corresponding school type. PMID- 27708693 TI - Anti-cancer effects of Gynostemma pentaphyllum (Thunb.) Makino (Jiaogulan). AB - Gynostemma pentaphyllum (Thunb.) Makino (GpM) (Jiaogulan) has been widely used in Chinese medicine for the treatment of several diseases, including hepatitis, diabetes and cardiovascular disease. Furthermore, GpM has recently been shown to exhibit potent anti-cancer activities. In this review, we have summarized recent research progress on the anti-cancer activities and mechanisms of action of GpM, as well as determining the material basis for the anti-cancer effects of GpM by searching the PubMed, Web of Science and China National Knowledge Infrastructure databases. The content of this review is based on studies reported in the literature pertaining to the chemical components or anti-cancer effects of GpM up until the beginning of August, 2016. This search of the literature revealed that more than 230 compounds have been isolated from GpM, and that most of these compounds (189) were saponins, which are also known as gypenosides. All of the remaining compounds were classified as sterols, flavonoids or polysaccharides. Various extracts and fractions of GpM, as well as numerous pure compounds isolated from this herb exhibited inhibitory activity towards the proliferation of cancer cells in vitro and in vivo. Furthermore, the results of several clinical studies have shown that GpM formula could have potential curative effects on cancer. Multiple mechanisms of action have been proposed regarding the anti-cancer activities of GpM, including cell cycle arrest, apoptosis, inhibition of invasion and metastasis, inhibition of glycolysis and immunomodulating activities. PMID- 27708696 TI - Differences in tobacco smoking prevalence and frequency between adolescent Palestine refugee and non-refugee populations in Jordan, Lebanon, Syria, and the West Bank: cross-sectional analysis of the Global Youth Tobacco Survey. AB - BACKGROUND: Evidence is conflicting as to the whether tobacco smoking prevalence is higher in refugee than non-refugee populations. The aim of this study was to compare the prevalence and frequency of tobacco smoking in Palestine refugee and non-refugee adolescent populations in the Middle East. METHODS: We conducted a cross-sectional analysis of the Global Youth Tobacco Survey (GYTS) conducted in Jordan, Lebanon, Syria, and the West Bank among adolescent Palestine refugees and non-refugees. Age- and sex-adjusted regression models assessed the association between refugee status and current (past-30 day) tobacco use prevalence and frequency. RESULTS: Prevalence estimates for current tobacco smoking were similar between Palestine refugee and non-refugee groups in Jordan (26.7 % vs. 24.0 %), Lebanon (39.4 % vs. 38.5 %), and the West Bank (39.5 % vs. 38.4 %). In Syria, Palestine refugees had nearly twice the odds of current tobacco smoking compared to non-refugees (23.2 % vs. 36.6 %, AOR 1.96, 95 % CI 1.46-2.62). Palestine refugees consumed more cigarettes per month than non-refugees in Lebanon (beta 0.57, 95 % CI 0.17-0.97) and Palestine refugees consumed more waterpipe tobacco per month than non-refugees in Syria (beta 0.40, 95 % CI 0.19-0.61) and the West Bank (beta 0.42, 95 % CI 0.21-0.64). CONCLUSIONS: Current tobacco smoking prevalence is in excess of 20 % in both adolescent Palestine refugee and non refugee populations in Middle Eastern countries, however Palestine refugees may smoke tobacco more frequently than non-refugees. Comparison of simple prevalence estimates may therefore mask important differences in tobacco use patterns within population groups. PMID- 27708697 TI - Information systems for mental health in six low and middle income countries: cross country situation analysis. AB - BACKGROUND: Research on information systems for mental health in low and middle income countries (LMICs) is scarce. As a result, there is a lack of reliable information on mental health service needs, treatment coverage and the quality of services provided. METHODS: With the aim of informing the development and implementation of a mental health information sub-system that includes reliable and measurable indicators on mental health within the Health Management Information Systems (HMIS), a cross-country situation analysis of HMIS was conducted in six LMICs (Ethiopia, India, Nepal, Nigeria, South Africa and Uganda), participating in the 'Emerging mental health systems in low and middle income countries' (Emerald) research programme. A situation analysis tool was developed to obtain and chart information from documents in the public domain. In circumstances when information was inadequate, key government officials were contacted to verify the data collected. In this paper we compare the baseline policy context, human resources situation as well as the processes and mechanisms of collecting, verifying, reporting and disseminating mental health related HMIS data. RESULTS: The findings suggest that countries face substantial policy, human resource and health governance challenges for mental health HMIS, many of which are common across sites. In particular, the specific policies and plans for the governance and implementation of mental health data collection, reporting and dissemination are absent. Across sites there is inadequate infrastructure, few HMIS experts, and inadequate technical support and supervision to junior staff, particularly in the area of mental health. Nonetheless there are also strengths in existing HMIS where a few mental health morbidity, mortality, and system level indicators are collected and reported. CONCLUSIONS: Our study indicates the need for greater technical and resources input to strengthen routine HMIS and develop standardized HMIS indicators for mental health, focusing in particular on indicators of coverage and quality to facilitate the implementation of the WHO mental health action plan 2013-2020. PMID- 27708699 TI - Brunei's teacher education programs: insights into students' coping and help seeking strategies to challenges. AB - BACKGROUND: Brunei started implementing its two main reformed teacher education programs, MTeach and MEd, in 2009. The reasons for these innovations included upgrading the standard of teacher training, increasing teaching effectiveness, and improving the quality of education in the country. The purpose of this study was to determine how student teachers coped with and sought help on the challenging programs. METHODS: Using an online survey design, 76 randomly selected recent graduate teachers responded appropriately to questionnaires administered to them by email. The obtained quantitative research information included demographic, coping, and help-seeking data, all analyzed by SPSS Version 22. RESULTS: Participants endorsed both the productive and nonproductive coping strategies. In addition, they depended more on peers, teachers and internet sources for help. Four major findings were obtained. First, task-oriented coping was the most important and significant predictor of success on the MTeach and MEd programs. Second, females had a higher likelihood of success compared to males (OR = 22.760, 95 % CI for OR = 12.848-40.320). Third, students who consulted relevant internet resources had higher odds for succeeding compared to those who did not (OR = 2.237, 95 % CI 1.196-4.183). Fourth, less-able students who collaboratively worked with the more-able peers were nearly two times more likely to perform better than those who did not (OR = 1.982, 95 % CI 1.082-3.630). CONCLUSIONS: Coping and help-seeking were positively and significantly related to academic achievement on the two Brunei main teacher education programs. Evidence from the present study suggested that vulnerable and at-risk trainee teachers needed appropriate interventions (educational, counseling and psychotherapy) related to effective use of task-oriented coping and seeking help via cooperative learning, internet sources, and teacher consultations,. Further research with interview probes was recommended to gain additional information on the problem and its solutions. PMID- 27708698 TI - Achievements of the Australian Access to Allied Psychological Services (ATAPS) program: summarising (almost) a decade of key evaluation data. AB - BACKGROUND: Introduced in July 2001, Australian Access to Allied Psychological Services (ATAPS) was the inaugural national policy initiative to provide community access to government-funded psychological services in primary care. Our aim was to examine the achievements of ATAPS in relation to its stated objectives using a set of indicators that largely drew on data from a minimum data set that we designed for the evaluation of ATAPS. METHODS: We used de-identified professional-, consumer- and session-level data from the minimum dataset, and secondary analyses of our quantitative and qualitative data collected for a series of specific evaluation studies. Available data covered the period from 1 July 2003 to 31 December 2012. RESULTS: Approximately 350,000 referrals were made to the ATAPS program over the 9.5 year analysis period, 79 % of which resulted in services. Over 1.4 million sessions were offered. Overall, 29 % of consumers were male, 4 % children, and 3 % Aboriginal people; 54 % of consumers had depression and 41 % an anxiety disorder; at least 60 % were on low incomes; and around 50 % resided outside of major cities. The most common interventions delivered were cognitive and behavioural therapies. Selected outcome measures indicated improvement in mental health symptoms. CONCLUSIONS: Access to Allied Psychological Services achieved its objectives within a decade of operation. The program delivered evidence-based services to a substantial number of consumers who were disadvantaged and historically would not have accessed services. Importantly, where data were available, there were indications that ATAPS achieved positive clinical outcomes for consumers. This suggests that ATAPS carved an important niche by successfully addressing unmet need of hard-to-reach consumers and through means that were not available via other programs. It will be interesting to see the effects from July 2016 of the reform of ATAPS, which will see ATAPS subsumed under psychological services commissioned by regional primary care organisations. PMID- 27708700 TI - Fluid management in pre-eclampsia. AB - Intravenous fluid given to women with pre-eclampsia may be a necessary form of treatment; however, intravenous fluid therapy can also cause iatrogenic pulmonary oedema. The indications for the use of intravenous fluids, the titration of the amount of fluid given and the use of invasive monitoring have not been subject to adequate examination in randomised studies. Clinical experience, combined with available evidence and a reasoned approach are the basis for a suggested management algorithm. PMID- 27708702 TI - Marfan's syndrome and other aortopathies in pregnancy. AB - Aortopathies, or disease affecting the aorta, are associated with a significant mortality risk for the mother and foetus during pregnancy because of an increased rate of aortic dissection. The hereditary aortopathies; Marfan's syndrome, bicuspid aortic valve, Loeys-Dietz syndrome, Ehlers-Danlos (type IV) syndrome, Turner's syndrome and nonsyndromic familial thoracic aortic aneurysm and dissection are all associated with an increased risk of aortic dissection particularly during the third trimester and early postpartum period. Maternal outcome in pregnancy depends on the underlying disorder and the aortic dimensions prior to pregnancy. The foetus has up to 50% chance of inheriting the underlying genetic defect. Vasculitis, particularly Takayasu's arteritis may also be a problem in pregnancy and predispose to aortic dissection. Prepregnancy review, including careful assessment of the aorta and prophylactic aortic surgery for an aortic aneurysm may reduce the risk of aortic dissection in pregnancy for some of the aortopathies but for women with Marfan's syndrome, Loeys-Dietz syndrome and Ehlers-Danlos (vascular type IV) who have had surgery, the risk of death remains high. A subgroup of women with Marfan's syndrome or a bicuspid aortic valve and normal aortic dimensions prepregnancy should do well in a pregnancy. Multidisciplinary pregnancy care with agreement on pregnancy follow-up, delivery and postpartum care with a crisis plan for an aortic dissection can improve pregnancy outcome and ensure prompt management of an aortic dissection should it occur. PMID- 27708701 TI - The use of thrombolytic therapy in pregnancy. AB - The relative hypercoagulable state of pregnancy leads to an increased risk of thrombotic complications, of which some may be life-threatening or medically devastating. In the non-pregnant patient, the current guidelines suggest thrombolysis as the primary treatment in acute ischemic stroke, myocardial infarction when percutaneous intervention is unavailable, certain cases of mechanical valve thrombosis, and pulmonary embolism with hemodynamic compromise or shock. Given that clinical trial data regarding thrombolytic use in pregnant women are absent due to exclusion, the goal of this review is to summarize the available published data regarding the use of thrombolytic agents and subsequent outcomes and complications in pregnant women. Overall, the use of thrombolytic agents in pregnancy is associated with a relatively low reported complication rate, especially given the severe medical conditions for which they are indicated. The data would suggest that thrombolysis should be considered for appropriate indications similar to that of non-pregnant patients. However, caution should be exercised when drawing conclusions regarding maternal and fetal safety, given the lack of controlled clinical trials including pregnant women and the nature of the weak evidence level of the cumulative data presented in this review. PMID- 27708704 TI - Diagnostic effectiveness of 75 g oral glucose tolerance test for gestational diabetes in India based on the International Association of the Diabetes and Pregnancy Study Groups guidelines. AB - BACKGROUND: To determine the diagnostic effectiveness of the fasting and one-hour plasma glucose levels for gestational diabetes (GDM) based on International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria. METHODS: A Cross-sectional study that included 2348 pregnant women booked for antenatal care in 2011 at a tertiary care perinatal institute. Pregnant women underwent a 75 g oral glucose tolerance test (OGTT) between 24 and 28 weeks of gestation. Outcome measures include the incidence of GDM based on the IADPSG criteria and the diagnostic effectiveness of the recommended fasting and one-hour plasma glucose cut-off if used in isolation. RESULTS: The incidence of GDM was 21.81% (n = 520, 95% CI: 20.15, 23.57) with the IADPSG criteria. A fasting plasma glucose cut-off 92 mg/dL, in isolation, correctly classified 87.16% of GDM, with a specificity of 96.08%, clinically significant positive likelihood ratio (14.08) and a post-test probability of 79.71%. The one-hour 75 g test, in isolation, correctly classified 85.74% of GDM, had specificity of 99.68% and clinically significant positive likelihood ratio (111.12) and post-test probability of 96.87%. The application of the World Health Organization criteria would misclassify 11.91% (95% CI: 10.66, 13.26) of GDM as normal. CONCLUSIONS: Additional testing of plasma glucose levels can be avoided for 18.25% (n = 435, 95% CI: 16.73, 19.84) if the IADPSG diagnostic criteria for GDM are applied with exit on a positive fasting or one-hour test result. PMID- 27708703 TI - Evaluation of home testing to improve follow up after gestational diabetes (Fingerstick Assessments of Sugar Two-months postpartum or FAST). AB - OBJECTIVE: Historically the rates of postpartum glucose tolerance testing for women with gestational diabetes (GDM) average a suboptimal 33%. Barriers include the need for new mothers to miss work and/or arrange for childcare in order to engage in a two-hour test at a commercial lab. This pilot study was initiated to test the theory that a home testing regimen would be accepted by patients and increase the rate of postpartum glucose assessments relative to published rates, without requiring additional health-care staff or resources to achieve this goal. STUDY DESIGN: Six weeks postpartum, women with GDM from an academic private practice were asked to check fingerstick blood glucose (FAST Protocol) four times a day for two days, and then obtain an oral glucose tolerance test (OGTT). The physician consultants saw the women each month during pregnancy and arranged the postpartum testing. RESULTS: Two of 69 refused to be consented. Twelve of the remaining 67(18%) women completed both the FAST regimen and the OGTT, three completed only the OGTT and five completed only the FAST regimen for a final follow-up rate of 20/67 (30%). The demands of caring for a newborn, or the annoyance of fingersticks, were barriers to compliance. CONCLUSIONS: In spite of intense physician involvement, this home testing regimen was not associated with an increase in the rates of women participating in postpartum glucose assessments. PMID- 27708705 TI - Beware of delayed severe brain swelling after intracerebral haematoma in HELLP syndrome. AB - Haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome is a condition associated with increased risk of adverse outcomes during pregnancy and peripartum, including neurological complications. We report the third case in the world literature of delayed brain swelling following cerebral haemorrhage as a complication of HELLP syndrome. A 36-year-old woman in labour developed HELLP, which was complicated with intracerebral haematoma. This was evacuated, but motor impairment persisted after surgery and unfortunately the patient died unexpectedly during the 11th postoperative day. Computer tomographic brain scans documented diffuse cerebral swelling, which we think may have been caused by cerebral vasospasm. Cerebral vasospasm should always be considered when managing patients who suffered from stroke complicating HELLP syndrome. Close monitoring is advised even in later stages of recovery. PMID- 27708706 TI - Bell's palsy in pregnancy: underlying HELLP syndrome or pre-eclampsia? AB - Bell's palsy is not uncommon during pregnancy. An association with pre-eclampsia (PE) has been reported previously. Furthermore, it has even been suggested that Bell's palsy could be a predictor of PE. We report three cases illustrating various possible aspects of this association, one of them including the features of HELLP (haemolysis, elevated liver enzymes, and low platelets) syndrome. PMID- 27708707 TI - Rare case of combined factor V and factor X deficiency in pregnancy: presenting as secondary postpartum haemorrhage in first pregnancy and successful outcome in second pregnancy. AB - Isolated factor V and factor X deficiency is a very rare condition affecting 1 in 500,000-1,000,000 persons worldwide. We present a rare first reported case of combined deficiency of factor V and factor X where the patient developed secondary postpartum haemorrhage in first pregnancy, after which she was diagnosed to have this rare disorder and her subsequent pregnancy was then successfully managed. PMID- 27708708 TI - A case of recurrent severe pre-eclampsia associated with essential cryofibrinogenaemia. AB - Essential cryofibrinogenaemia is a rare disorder characterized by cryofibrinogens without cryoglobulins. Connective tissue disorders and thrombophilia are known to increase risk of pre-eclampsia, but pre-eclampsia has not previously been reported in association with cryofibrinogenaemia. We report the case of a 32-year old woman with recurrent severe pre-eclampsia diagnosed with essential cryofibrinogenaemia. PMID- 27708709 TI - Severe metabolic alkalosis in pregnancy. AB - Metabolic alkalosis is uncommon in pregnancy and is most often the result of severe vomiting. If this is present at the time of delivery, transient metabolic derangement in the fetus can occur, potentially requiring additional organ support. A 22-year-old woman is described, who presented at 37 weeks gestation with a severe metabolic alkalosis, vomiting and acute renal and hepatic impairment. The investigations, management options and maternal and fetal outcome are described. PMID- 27708711 TI - Identification and characterization of putative xylose and cellobiose transporters in Aspergillus nidulans. AB - BACKGROUND: The conversion of lignocellulosic biomass to biofuels (second generation biofuel production) is an environmentally friendlier alternative to petroleum-based energy sources. Enzymatic deconstruction of lignocellulose, catalyzed by filamentous fungi such as Aspergillus nidulans, releases a mixture of mono- and polysaccharides, including hexose (glucose) and pentose (xylose) sugars, cellodextrins (cellobiose), and xylooligosaccharides (xylobiose). These sugars can subsequently be fermented by yeast cells to ethanol. One of the major drawbacks in this process lies in the inability of yeast, such as Saccharomyces cerevisiae, to successfully internalize sugars other than glucose. The aim of this study was, therefore, to screen the genome of A. nidulans, which encodes a multitude of sugar transporters, for transporters able to internalize non-glucose sugars and characterize them when introduced into S. cerevisiae. RESULTS: This work identified two proteins in A. nidulans, CltA and CltB, with roles in cellobiose transport and cellulose signaling, respectively. CltA, when introduced into S. cerevisiae, conferred growth on low and high concentrations of cellobiose. Deletion of cltB resulted in reduced growth and extracellular cellulase activity in A. nidulans in the presence of cellobiose. CltB, when introduced into S. cerevisiae, was not able to confer growth on cellobiose, suggesting that this protein is a sensor rather than a transporter. However, we have shown that the introduction of additional functional copies of CltB increases the growth in the presence of low concentrations of cellobiose, strongly indicating CltB is able to transport cellobiose. Furthermore, a previously identified glucose transporter, HxtB, was also found to be a major xylose transporter in A. nidulans. In S. cerevisiae, HxtB conferred growth on xylose which was accompanied by ethanol production. CONCLUSIONS: This work identified a cellobiose transporter, a xylose transporter, and a putative cellulose transceptor in A. nidulans. This is the first time that a sensor role for a protein in A. nidulans has been proposed. Both transporters are also able to transport glucose, highlighting the preference of A. nidulans for this carbon source. This work provides a basis for future studies which aim at characterizing and/or genetically engineering Aspergillus spp. transporters, which, in addition to glucose, can also internalize other carbon sources, to improve transport and fermentation of non-glucose sugars in S. cerevisiae. PMID- 27708712 TI - One pedigree we all may have come from - did Adam and Eve have the chromosome 2 fusion? AB - BACKGROUND: In contrast to Great Apes, who have 48 chromosomes, modern humans and likely Neandertals and Denisovans have and had, respectively, 46 chromosomes. The reduction in chromosome number was caused by the head-to-head fusion of two ancestral chromosomes to form human chromosome 2 (HSA2) and may have contributed to the reproductive barrier with Great Apes. RESULTS: Next generation sequencing and molecular clock analyses estimated that this fusion arose prior to our last common ancestor with Neandertal and Denisovan hominins ~ 0.74 - 4.5 million years ago. HYPOTHESES: I propose that, unlike recurrent Robertsonian translocations in humans, the HSA2 fusion was a single nonrecurrent event that spread through a small polygamous clan population bottleneck. Its heterozygous to homozygous conversion, fixation, and accumulation in the succeeding populations was likely facilitated by an evolutionary advantage through the genomic loss rather than deregulation of expression of the gene(s) flanking the HSA2 fusion site at 2q13. CONCLUSIONS: The origin of HSA2 might have been a critical evolutionary event influencing higher cognitive functions in various early subspecies of hominins. Next generation sequencing of Homo heidelbergensis and Homo erectus genomes and complete reconstruction of DNA sequence of the orthologous subtelomeric chromosomes in Great Apes should enable more precise timing of HSA2 formation and better understanding of its evolutionary consequences. PMID- 27708713 TI - New insights of karyoevolution in the Amazonian turtles Podocnemis expansa and Podocnemis unifilis (Testudines, Podocnemidae). AB - BACKGROUND: Cytogenetic studies were conducted in the Brazilian Amazon turtles, Podocnemis expansa Schweigger, 1912 (PEX) and Podocnemis unifilis Troschel, 1848 (PUN) to understand their karyoevolution. Their chromosomal complements were compared using banding techniques (C, G-, Ag-NOR and Chromomycin A3) and fluorescence in situ hybridization (FISH), and efforts were made to establish evolutionary chromosomal relationships within the Podocnemidae family. RESULTS: Our results revealed that both species have a chromosome complement of 2n = 28. For PEX and PUN, the fundamental numbers (FNs) were 54 and 52, respectively and the karyotypic formulas (KFs) were 24 m/sm + 2st + 2a and 22 m/sm + 2st + 4a, respectively. G-banding evidenced homologies between the two species and allowed identify a heteromorphic pair (chromosome pair 10) in PUN. In PEX, constitutive heterochromatin (CH) was found in the centromeric regions of pairs 1, 2, 4, 6 and 11 and on 9p. In PUN, CH was observed in the centromeric regions of all chromosomes, and in small proximal bands on 1p, 2p, 3q, 4q, 5q, 9q, 10q and 11q. Moreover, CH amplification was seen in one of the homologs of pair 10 (the heteromorphic pair). The CMA3 staining results were consistent with the CH findings. Ag-NOR staining showed that nucleolar organizing regions (NORs) were localized in the pericentromeric region of pair 1 in both species, and this result was confirmed by the 18S rDNA FISH probe. FISH with telomeric probes identified telomeric sequences in the distal regions of all chromosomes. In addition, interstitial telomeric sequences (ITSs) were present in seven chromosome pairs of PUN, perhaps reflecting the amplification of telomere-like sequences. FISH with a probe against the transposable element (TE), Rex 6, revealed that it is dispersed in euchromatic regions of the first chromosome pairs of both species. This is the first report describing the FISH-based analysis of PEX and PUN for the 18S rDNA, Rex 6 and human telomeric sequences. CONCLUSIONS: Our results contribute to clarifying the chromosomal homologies and rearrangement mechanisms that occurred during the evolution of these species, and may help researchers uncover new markers that will improve our understanding of the taxonomy and systematic classification of Podocnemidae.

PMID- 27708714 TI - The presence of two rare genomic syndromes, 1q21 deletion and Xq28 duplication, segregating independently in a family with intellectual disability. AB - BACKGROUND: 1q21 microdeletion syndrome is a rare contiguous gene deletion disorder with de novo or autosomal dominant inheritance patterns and its phenotypic features include intellectual disability, distinctive facial dysmorphism, microcephaly, cardiac abnormalities, and cataracts. MECP2 duplication syndrome is an X-linked recessive neurodevelopmental disorder characterized by intellectual disability, global developmental delay, and other neurological complications including late-onset seizures. Previously, these two different genetic syndromes have not been reported segregating independently in a same family. CASE PRESENTATION: Here we describe two siblings carrying either a chromosome 1q21 microdeletion or a chromosome Xq28 duplication. Using a comparative genomic hybridization (CGH) array, we identified a 1.24 Mb heterozygous deletion at 1q21 resulting in the loss of 9 genes in a girl with learning disability, hypothyroidism, short stature, sensory integration disorder, and soft dysmorphic features including cupped ears and a unilateral ear pit. We also characterized a 508 kb Xq28 duplication encompassing MECP2 in her younger brother with hypotonia, poor speech, cognitive and motor impairment. The parental CGH and quantitative PCR (qPCR) analyses revealed that the 1q21 deletion in the elder sister is de novo, but the Xq28 duplication in the younger brother was originally inherited from the maternal grandmother through the mother, both of whom are asymptomatic carriers. RT-qPCR assays revealed that the affected brother has almost double the amount of MECP2 mRNA expression compared to other family members of both genders including maternal grandmother and mother who have the same Xq28 duplication with no phenotype. This suggests the X chromosome with an Xq28 duplication in the carrier females is preferentially silenced. CONCLUSION: From our understanding, this would be the first report showing the independent segregation of two genetically unrelated syndromes, 1q21 microdeletion and Xq28 duplication, in a same family, especially in siblings. Although these two chromosomal abnormalities share some similar phenotypes such as intellectual disability, mild dysmorphic features, and cardiac abnormalities, the presence of two unrelated and rare syndromes in siblings is very unusual. Therefore, further comprehensive investigations in similar cases are required for future studies. PMID- 27708715 TI - 12p deletion spectrum syndrome: a new case report reinforces the evidence regarding the potential relationship to autism spectrum disorder and related developmental impairments. AB - BACKGROUND: Autism Spectrum Disorders (ASD) now encompass a broad heterogeneous group of people who present in the early developmental years with a wide range of social and communication deficits, which are typically also associated with complex repetitive behaviors and circumscribed interests. The target goal is to heighten readers' perception into the trend to personalize the distinct autistic and related developmental conditions encompassing the 12p region. CASE PRESENTATION: This is a case-report of a 4-year-old male who presented the core signs of ASD, which were thought to be related to a rare 12p13.2 deletion. We further reviewed the literature in order to outline the related developmental conditions in the 12p region. Aside from this patient reported here, we found an additional number of 43 cases described in the medical literature since 1974, that have been related to deletions in the 12p region. However, to the best of our knowledge, none of the previous had been specifically linked to the 12p13.2 band. CONCLUSIONS: The 12p deletion spectrum is rarely described as part of the selective genotypes thought to be related to ASD. Even inside of a small piece of the puzzle, there might be ample variation in the behavioral and clinical phenotypes of children and adults presenting with this particular genetic profile. In that regard, the particular 12p13.2 distal deletion presentation is one of the possible genotypes encompassed by the "12p deletion spectrum syndrome", that might be potentially connected to the diagnosis of ASD and related developmental disorders.

AB - BACKGROUND: In epigenetic research, both the increasing ease of high-throughput sequencing and a greater interest in genome-wide studies have resulted in an exponential flooding of epigenetic-related data in public domain. This creates an opportunity for exploring data outside the limits of any specific query-centred study. Such data have to undergo standard primary analyses that are accessible with multiple well-stabilized programs. Further downstream analyses, such as genome-wide comparative, correlative and quantitative analyses, are critical in deciphering key biological features. However, these analyses are only accessible for computational researchers and completely lack platforms capable of handling, analysing and linking multiple interdisciplinary datasets with efficient analytical methods. RESULTS: Here, we present EpiMINE, a program for mining epigenomic data. It is a user-friendly, stand-alone computational program designed to support multiple datasets, for performing genome-wide correlative and quantitative analysis of ChIP-seq and RNA-seq data. Using data available from the ENCODE project, we illustrated several features of EpiMINE through different biological scenarios to show how easy some known observations can be verified. These results highlight how these approaches can be helpful in identifying novel biological features. CONCLUSIONS: EpiMINE performs different kinds of genome-wide quantitative and correlative analyses, using ChIP-seq- and RNA-seq-related datasets. Its framework enables it to be used by both experimental and computational researchers. EpiMINE can be downloaded from https://sourceforge.net/projects/epimine/. PMID- 27708718 TI - A single capsule formulation of RHB-104 demonstrates higher anti-microbial growth potency for effective treatment of Crohn's disease associated with Mycobacterium avium subspecies paratuberculosis. AB - BACKGROUND: Most recently we reported that RHB-104 triple antibiotics combination in culture is bactericidal and should be effective for treatment of Crohn's disease (CD)-associated with Mycobacterium avium subspecies paratuberculosis (MAP) (Alcedo et al. in Gut Pathog 14:32, 2016). The combination exhibited unique synergistic antimicrobial growth activity. The proprietary RHB-104 capsule formulation contains active ingredients (63.3 % Clarithromycin (CLA), 6.7 % Clofazimine (CLO) and 30 % Rifabutin (RIF)). In our earlier study, we could not dissolve the proprietary RHB-104 capsule formulation in one compatible solvent. Consequently, we re-created RHB-104 analog by adding appropriate concentrations of each of the three antibiotics into the cultures. The Minimum inhibitory concentration (MIC) for RHB-104 analog, CLA, CLO, RIF, CLA-CLO, CLA-RIF, CLO-RIF and their individual solvents were reported earlier (Alcedo et al. in Gut Pathog 14:32, 2016). In this study, we succeeded in dissolving the proprietary RHB-104 capsule formulation in a single proprietary solvent. This study is designed to compare of the MIC the proprietary RHB-104 capsule formulation to RHB-104 analog against MAP and other microorganisms. METHODS: BD BactecTM MGITTM Para-TB medium (Sparks, MD) system was used to determine the MIC of the proprietary RHB-104 capsule formulation and RHB-104 analog and their solvents against MAP and several other microorganisms. The final concentration of solvents used to dissolve all the drugs were <=0.5 % (v/v). RESULTS: The MIC for the RHB-104 proprietary solvent against MAP was consistent against all microorganisms tested in the study at 12.5 % (v/v). The MIC for the proprietary RHB-104 capsule formulation was similar to RHB-104 analog against several MAP clinical strains with MIC <= 0.2 MUg/mL. The MIC for the proprietary RHB-104 capsule formulation was at 2.0 MUg/mL against MAP strain MS 137 and M. avium strain JF7 compared to 4.0 ug/mL for RHB 104 analog. Similarly, the MIC of RHB-104 formulation capsule was significantly lower than RHB-104 analog against M. tuberculosis HR237, M. fortuitism subspecies fortuitum, M. smegmatis ATCC 27199, Staphylococcus aureus ATCC 25923 and Listeria monocytogenes ATCC 19112. CONCLUSION: The data demonstrated that the proprietary RHB-104 capsule formulation is more potent in culture against Mycobacteria and other microorganisms especially those with MIC >0.2. Formulation of multi-drugs in a single capsule results in potent synergistic anti-microbial activity far exceeds treatment the culture with multi-individually dissolved drugs. RHB-104 capsule formulation should be more effective to eradicate MAP infection in patients with CD. The study provides evidence that combining weak antibiotics in one formulation might be the new silver bullet to combat bacteria.

AB - Much of the clinical and research attention for Parkinson's Disease (PD) has focused on mild to moderate stages. As the disease advances, it can become difficult for patients to attend clinical visits. These patients are often lost to follow-up, and consequently, vanish from the pool of potential research subjects who could inform our management of this understudied population. We aim to increase awareness about this population and potential interventions to improve continuity of care and foster research in advanced PD. PMID- 27708721 TI - The impact of MTHFR 677C -> T risk knowledge on changes in folate intake: findings from the Food4Me study. AB - BACKGROUND: It is hypothesised that individuals with knowledge of their genetic risk are more likely to make health-promoting dietary and lifestyle changes. The present study aims to test this hypothesis using data from the Food4Me study. This was a 6-month Internet-based randomised controlled trial conducted across seven centres in Europe where individuals received either general healthy eating advice or varying levels of personalised nutrition advice. Participants who received genotype-based personalised advice were informed whether they had the risk (CT/TT) (n = 178) or non-risk (CC) (n = 141) alleles of the methylenetetrahydrofolate reductase (MTHFR) gene in relation to cardiovascular health and the importance of a sufficient intake of folate. General linear model analysis was used to assess changes in folate intake between the MTHFR risk, MTHFR non-risk and control groups from baseline to month 6 of the intervention. RESULTS: There were no differences between the groups for age, gender or BMI. However, there was a significant difference in country distribution between the groups (p = 0.010). Baseline folate intakes were 412 +/- 172, 391 +/- 190 and 410 +/- 186 MUg per 10 MJ for the risk, non-risk and control groups, respectively. There were no significant differences between the three groups in terms of changes in folate intakes from baseline to month 6. Similarly, there were no changes in reported intake of food groups high in folate. CONCLUSIONS: These results suggest that knowledge of MTHFR 677C -> T genotype did not improve folate intake in participants with the risk variant compared with those with the non risk variant.

AB - Due to the synergic relationship between medical chemistry, bioinformatics and molecular simulation, the development of new accurate computational tools for small molecules drug design has been rising over the last years. The main result is the increased number of publications where computational techniques such as molecular docking, de novo design as well as virtual screening have been used to estimate the binding mode, site and energy of novel small molecules. In this work I review some tools, which enable the study of biological systems at the atomistic level, providing relevant information and thereby, enhancing the process of rational drug design. PMID- 27708722 TI - PITX3 promoter methylation is a prognostic biomarker for biochemical recurrence free survival in prostate cancer patients after radical prostatectomy. AB - BACKGROUND: Molecular biomarkers that might help to distinguish between more aggressive and clinically insignificant prostate cancers (PCa) are still urgently needed. Aberrant DNA methylation as a common molecular alteration in PCa seems to be a promising source for such biomarkers. In this study, PITX3 DNA methylation (mPITX3) and its potential role as a prognostic biomarker were investigated. Furthermore, mPITX3 was analyzed in combination with the established PCa methylation biomarker PITX2 (mPITX2). METHODS: mPITX3 and mPITX2 were assessed by a quantitative real-time PCR and by means of the Infinium HumanMethylation450 BeadChip. BeadChip data were obtained from The Cancer Genome Atlas (TCGA) Research Network. DNA methylation differences between normal adjacent, benign hyperplastic, and carcinomatous prostate tissues were examined in the TCGA dataset as well as in prostatectomy specimens from the University Hospital Bonn. Retrospective analyses of biochemical recurrence (BCR) were conducted in a training cohort (n = 498) from the TCGA and an independent validation cohort (n = 300) from the University Hospital Bonn. All patients received radical prostatectomy. RESULTS: In PCa tissue, mPITX3 was increased significantly compared to normal and benign hyperplastic tissue. In univariate Cox proportional hazards analyses, mPITX3 showed a significant prognostic value for BCR (training cohort: hazard ratio (HR) = 1.83 (95 % CI 1.07-3.11), p = 0.027; validation cohort: HR = 2.56 (95 % CI 1.44-4.54), p = 0.001). A combined evaluation with PITX2 methylation further revealed that hypermethylation of a single PITX gene member (either PITX2 or PITX3) identifies an intermediate risk group. CONCLUSIONS: PITX3 DNA methylation alone and in combination with PITX2 is a promising biomarker for the risk stratification of PCa patients and adds relevant prognostic information to common clinically implemented parameters. Further studies are required to determine whether the results are transferable to a biopsy-based patient cohort. Trial registration: Patients for this unregistered study were enrolled retrospectively. PMID- 27708725 TI - Influence of Enamel Thickness on Bleaching Efficacy: An In-Depth Color Analysis. AB - This study evaluated the influence of different enamel thicknesses and bleaching agents on treatment efficacy in-depth by spectrophotometry color analysis. Eighty bovine dental fragments were previously stained in black tea solution and randomly assigned into eight groups (n=10), 1.75mm dentin thickness and different enamel thicknesses as follows: 0.5mm, 1.0mm planned, 1.0mm unplanned (aprismatic enamel), and absence of enamel. The 10% carbamide peroxide (CP) and 35% hydrogen peroxide (HP) bleaching gels were applied on the enamel surface following the manufacturer's recommendations. Color of underlying dentin was evaluated at four times: after staining with tea (baseline) and after each one of the three weeks of bleaching treatment, by CIE L*a*b* system using reflectance spectrophotometer (CM 700d, Konica Minolta). The DeltaE, DeltaL, Deltaa, and Deltab values were recorded and subjected to repeated measures ANOVA and Tukey's test (alpha=0.05). The results showed an increase on lightness (L*), with decreased redness (a*) and yellowness (b*). At first and second week, bleaching with CP showed higher whitening effectiveness compared to bleaching with HP and the presence of aprismatic enamel significantly reduced DeltaE for bleaching with CP. After three weeks of bleaching, few differences were observed between CP and HP groups, and outer enamel layer caused no influence on bleaching effectiveness. Overall, both at-home and in-office bleaching treatments were effective and the presence of aprismatic enamel did not interfere on the whitening efficacy. PMID- 27708726 TI - Bisphenol A Release: Survey of the Composition of Dental Composite Resins. AB - BACKGROUND: Bisphenol A (BPA) is an endocrine disruptor with potential toxicity. Composite resins may not contain pure BPA, but its derivatives are widely used. Several studies found doses of BPA or its derivatives in saliva or urine of patients after composite resin placement. OBJECTIVE: The aims of this study were to establish an exhaustive list of composite resins marketed in Europe and their composition, and to assess the extent of BPA derivatives used. METHODS: A research on manufacturers' websites was performed to reference all composite resins marketed in Europe, then their composition was determined from both material safety data sheets and a standardized questionnaire sent to manufacturers. Manufacturers had to indicate whether their product contained the monomers listed, add other monomers if necessary, or indicate "not disclosed". RESULTS: 160 composite resins were identified from 31 manufacturers and 23 manufacturers (74.2%) responded to the survey. From the survey and websites, the composition of 130 composite resins (81.2%) was: 112 (86.2%) based on BPA derivatives, 97 (74.7%) on bis-GMA, 17 (13.1%) without monomer derived from BPA (UDMA, sometimes with TEGDMA) and 6 (4.6%) with UDMA (only); 1 (0.8%) did not contain a BPA derivative or UDMA or TEGDMA. Pure BPA was never reported. CONCLUSION: This work has established a list of 18 composite resins that contain no BPA derivative. Manufacturers should be required to report the exact composition of their products as it often remains unclear or incomplete. PMID- 27708727 TI - Masseter Muscle Activity in Track and Field Athletes: A Pilot Study. AB - Teeth clenching has been shown to improve remote muscle activity (by augmentation of the Hoffmann reflex), and joint fixation (by decreased reciprocal inhibition) in the entire body. Clenching could help maintain balance, improve systemic function, and enhance safety. Teeth clenching from a sports dentistry viewpoint was thought to be important and challenging. Therefore, it is quite important to investigate mastication muscles' activity and function during sports events for clarifying a physiological role of the mastication muscle itself and involvement of mastication muscle function in whole body movement. Running is a basic motion of a lot of sports; however, a mastication muscles activity during this motion was not clarified. Throwing and jumping operation were in a same situation. The purpose of this study was to investigate the presence or absence of masseter muscle activity during track and field events. In total, 28 track and field athletes took part in the study. The Multichannel Telemetry system was used to monitor muscle activity, and the electromyograms obtained were synchronized with digital video imaging. The masseter muscle activity threshold was set 15% of maximum voluntary clenching. As results, with few exceptions, masseter muscle activity were observed during all analyzed phases of the 5 activities, and that phases in which most participants showed masseter muscle activity were characterized by initial acceleration, such as in the short sprint, from the commencement of throwing to release in both the javelin throw and shot put, and at the take-off and landing phases in both jumps.

AB - BACKGROUND: Only limited data are available on the prevalence of hepatitis B in patients with proven rheumatic diseases and thus the risk of reactivation under immunosuppressive therapy. OBJECTIVE: To analyse hepatitis B serology in patients with rheumatic diseases prior to therapy. METHOD: In total, 1,338 patient records were analysed for HBsAg, HBsAb and HBcAb in a cross-sectional, single-centre study between 2011 and 2015 at first presentation. Data acquisition was realized using electronic patient files created during routine care. The main variables considered as predictors for HBV reactivation included (i) the exact type of rheumatic disease and (ii) the therapeutically induced immunosuppression. RESULTS: Overall, 5.9% of patients (n=79) had proven contact with hepatitis B (HBcAb positive), and HBsAb were not detected in 1.3% (n=18). The rate of vaccinated subjects was 7.8%. HBsAg was detected in 3 patients (0.2%). In addition, 70.3% of patients were treated during the course of rheumatologic disease previously or currently with glucocorticoids, 85.2% with disease modifying anti-rheumatic drugs (DMARDs) and 20.1% with a biologic agent ( e.g. , anti-IL-6, anti-TNFalpha, anti-CD20, CTLA4Ig or anti-IL-12/23). CONCLUSION: Prevalence of hepatitis B serostatus in the analysed rheumatic patients regarding HBs-Ag and HBcAb with or without HBsAb prior to therapy does not differ from the data published for the general population in Germany. However, the rate of hepatitis B vaccinated patients was lower. In general, a significant portion of patients (5.9%) has been exposed to HBV and therefore exhibited an increased risk of reactivation of hepatitis B when undergoing immunosuppressive therapy. PMID- 27708730 TI - Irreparable Rotator Cuff Tears: Restoring Joint Kinematics by Tendon Transfers. AB - BACKGROUND: Tendon transfers can be a surgical treatment option in managing younger, active patients with massive irreparable rotator cuff tears. The purpose of this article is to provide an overview of the use of tendon transfers to treat massive irreparable rotator cuff tears and to summarize clinical outcomes. METHODS: A selective literature search was performed and personal surgical experiences are reported. RESULTS: Latissimus dorsi transfers have been used for many years in the management of posterosuperior rotator cuff tears with good reported clinical outcomes. It can be transferred without or with the teres major (L'Episcopo technique). Many surgical techniques have been described for latissimus dorsi transfer including single incision, double incision, and arthroscopically assisted transfer. Transfer of the pectoralis major tendon is the most common tendon transfer procedure performed for anterosuperior rotator cuff deficiencies. Several surgical techniques have been described, however transfer of the pectoralis major beneath the coracoid process has been found to most closely replicate the force vector that is normally provided by the intact subscapularis. CONCLUSION: Tendon transfers can be used successfully in the management of younger patients with massive irreparable rotator cuff tears and minimal glenohumeral arthritis. Improvements in clinical outcomes scores and range of motion have been demonstrated. This can delay arthroplasty, which is of particular importance for younger patients with high functional demands. PMID- 27708732 TI - The Role of Platelet Rich Plasma (PRP) and Other Biologics for Rotator Cuff Repair. AB - BACKGROUND: Surgical treatment of rotator cuff tears has consistently demonstrated good clinical and functional outcomes. However, in some cases, the rotator cuff fails to heal. While improvements in rotator cuff constructs and biomechanics have been made, the role of biologics to aid healing is currently being investigated. METHODS: A selective literature search was performed and personal surgical experiences are reported. RESULTS: Biologic augmentation of rotator cuff repairs can for example be performed wtableith platelet-rich plasma (PRP) and mesenchymal stem cells (MSCs). Clinical results on PRP application have been controversial. Application of MSCs has shown promise in animal studies, but clinical data on its effectiveness is presently lacking. The role of Matrix Metalloproteinase (MMP) inhibitors is another interesting field for potential targeted drug therapy after rotator cuff repair. CONCLUSIONS: Large randomized clinical studies need to confirm the benefit of these approaches, in order to eventually lower retear rates and improve clinical outcomes after rotator cuff repair. PMID- 27708731 TI - Risk Factors, Pathobiomechanics and Physical Examination of Rotator Cuff Tears. AB - BACKGROUND: It is important to appreciate the risk factors for the development of rotator cuff tears and specific physical examination maneuvers. METHODS: A selective literature search was performed. RESULTS: Numerous well-designed studies have demonstrated that common risk factors include age, occupation, and anatomic considerations such as the critical shoulder angle. Recently, research has also reported a genetic component as well. The rotator cuff axially compresses the humeral head in the glenohumeral joint and provides rotational motion and abduction. Forces are grouped into coronal and axial force couples. Rotator cuff tears are thought to occur when the force couples become imbalanced. CONCLUSION: Physical examination is essential to determining whether a patient has an anterosuperior or posterosuperior tear. Diagnostic accuracy increases when combining a series of examination maneuvers. PMID- 27708733 TI - Patch-Augmented Rotator Cuff Repair and Superior Capsule Reconstruction. AB - BACKGROUND: Massive rotator cuff tears in active patients with minimal glenohumeral arthritis remain a particular challenge for the treating surgeon. METHODS: A selective literature search was performed and personal surgical experiences are reported. RESULTS: For patients with irreparable rotator cuff tears, a reverse shoulder arthroplasty or a tendon transfer are often performed. However, both procedures have rather high complication rates and debatable long term results, particularly in younger patients. Therefore, patch-augmented rotator cuff repair or superior capsule reconstruction (SCR) have been recently developed as arthroscopically applicable treatment options, with promising biomechanical and early clinical results. CONCLUSION: For younger patients with irreparable rotator cuff tears wishing to avoid tendon transfers or reverse total shoulder arthroplasty, both patch-augmentation and SCR represent treatment options that may delay the need for more invasive surgery. PMID- 27708734 TI - Arthroscopic Debridement for Irreparable Rotator Cuff Tears. AB - BACKGROUND: Arthroscopic debridement represents a salvage procedure for irreparable rotator cuff tears. It is important to accurately diagnose the patient for irreparable rotator cuff tears. The diagnosis and the therapeutic options must be explained to the patient. It is mandatory that the patient understands the primary goal of the arthroscopic debridement being reduction of pain, not improving strength or function. METHODS: The procedure consists of 7 distinct steps to debride the soft tissues and alleviate pain. RESULTS: Even though there is a lack of evidence that this procedure is superior to other therapeutic options, it has shown good results in patients with the main complaint of pain. CONCLUSION: The results reported in some studies should, however, be interpreted with caution, taking into consideration the substantial structural damage in irreparable defects. PMID- 27708735 TI - Summary of Meta-Analyses Dealing with Single-Row versus Double-Row Repair Techniques for Rotator Cuff Tears. AB - BACKGROUND: Several meta-analyses of randomized clinical trials have been performed to analyze whether double-row (DR) rotator cuff repair (RCR) provides superior clinical outcomes and structural healing compared to single-row (SR) repair. The purpose of this study was to sum up the results of meta-analysis comparing SR and DR repair with respect on clinical outcomes and re-tear rates. METHODS: A literature search was undertaken to identify all meta-analyses dealing with randomized controlled trials comparing clinical und structural outcomes after SR versus DR RCR. RESULTS: Eight meta-analyses met the eligibility criteria: two including Level I studies only, five including both Level I and Level II studies, and one including additional Level III studies. Four meta analyses found no differences between SR and DR RCR for patient outcomes, whereas four favored DR RCR for tears greater than 3 cm. Two meta-analyses found no structural healing differences between SR and DR RCR, whereas six found DR repair to be superior for tears greater than 3 cm tears. CONCLUSION: No clinical differences are seen between single-row and double-row repair for small and medium rotator cuff tears after a short-term follow-up period with a higher re tear rate following single-row repairs. There seems to be a trend to superior results with double-row repair in large to massive tear sizes. PMID- 27708736 TI - Prognosis Driven Rehabilitation After Rotator Cuff Repair Surgery. AB - BACKGROUND: Rehabilitation after rotator cuff repair surgery has been the focus of several clinical trials in the past decade. Many illuminate new evidence with regard to the prognosis of structural and functional success after surgery. METHODS: A selective literature search was performed and personal physiotherapeutic and surgical experiences are reported. RESULTS: Post-operative rehabilitation parameters, namely the decision to delay or allow early range of motion after surgery, play a large role in the overall success after surgery. Using a prognosis driven rehabilitation program offers clinicians a means of prescribing optimal rehabilitation parameters while ensuring structural and functional success. This commentary aims to synthesize the evidence in a spectrum of prognostic factors to guide post-operative rehabilitation. CONCLUSION: The optimal rehabilitation program after rotator cuff repair surgery is debatable; therefore, we suggest using a spectrum of prognostic factors to determine a rehabilitation program suited to ensure structural and functional success, quickly and safely. PMID- 27708737 TI - Non-Operative Management of Rotator Cuff Tears. AB - BACKGROUND: The role of nonoperative management for rotator cuff tears remains a matter of debate. Clinical results reported in the literature mainly consist of level IV studies, oftentimes combining a mixed bag of tear sizes and configurations, and are contradictory to some extent. METHODS: A selective literature search was performed and personal surgical experiences are reported. RESULTS: Most studies show an overall success rate of around 75% for nonoperative treatment. However, the majority of studies also present a progression of tear size and fatty muscle infiltration over time, with however debatable clinical relevance for the patient. Suggested factors associated with progression of a rotator cuff tear are an age of 60 years or older, full-thickness tears, and fatty infiltration of the rotator cuff muscles at the time of initial diagnosis. CONCLUSION: Non-operative management is indicated for patients with lower functional demands and moderate symptoms, and/or of course for those refusing to have surgery. Close routinely monitoring regarding development of tear size should be performed, especially in patients that remain symptomatic during nonoperative treatment. To ensure judicious patient counseling, it has to be taken into account that 1) tears that are initially graded as reparable may become irreparable over time, and 2) results after secondary surgical therapy after failed nonoperative treatment are usually reported to be inferior to those who underwent primary tendon repair. PMID- 27708738 TI - Are We Economically Efficient Enough to Increase the Potential of in Vitro Proliferation of Osteoblasts by Means of Pharmacochemical Agents? AB - BACKGROUND: The aim of this study was to test the necessity of using expensive and unaccesible pharmacological-chemical agents in the proliferation of bone tissue cultures and in the induction of mineralized matrix formation to increase the osteogenic effect. METHODS: For this purpose, human primary cell cultures were prepared and then divided into two groups. Whereas the cells in group I were fed with an osteoblast stimulator medium containing Dulbecco's Modified Eagle Medium (DMEM) and beta-glycerophosphate, the cells in group II were fed with DMEM containing dexamethasone and 2-phospho-L-ascorbic acid trisodium salt. Both groups were evaluated in terms of viability, toxicity, and proliferation and then compared in terms of cell surface morphology through inverted light and environmental scanning electron microscopy. In addition to immunoflow cytometric analyses, the effects of alkaline phosphatase activities were evaluated using the spectrophotometric method to examine the osteoblastic activities. Costs were calculated in the currency of the European Union (Euros). The Tukey Honestly Significant Difference test was used to reach the statistical evaluation of the data after the analysis of variance. RESULTS: It was reported that the level of the alkaline phosphates was higher in group I compared to group II. It was observed that the surface morphology quality, the number of living cells, and proliferation were higher in group II and that the results were deemed statistically significant. CONCLUSION: It was found that the 2-phospho-L-ascorbic acid trisodium salt and dexamethasone mixture was as effective as the expensive commercial kits on the osteogenic effect on human primary bone tissue. PMID- 27708739 TI - Is Casting for Non-Displaced Simple Scaphoid Waist Fracture Effective? A CT Based Assessment of Union. AB - OBJECTIVE: The purpose of this study is to report the union rate and time to union for acute non-displaced scaphoid waist fractures treated with a short arm thumb spica cast. METHODS: A database was searched (2006-2013) to identify acute undisplaced scaphoid waist fractures. Cases that were not given a trial of casting were excluded (n=33). X-rays, CT scans and health records for each patient were reviewed to extract data. RESULTS: 172 patients met inclusion criteria. There were 138 males, 34 females, the mean age was 30 +/- 16 years. The union rate was 99.4% (1 nonunion/172 subjects). The mean time to union was approximately 7.5 weeks (53 +/- 37 days). Energy of injury, age or gender did not affect union rates or time to union. Cysts did not affect the union rate (p=0.73) but patients with cystic resorption along the fracture line required approximately 10 weeks for union (69 +/- 60 days) compared to 7 weeks (51 +/- 34 days) for those without cysts (p=0.05). Diabetes did not affect the union rate (p=0.81) but was found to increase the risk of delayed union (p=0.05). There was a weak, but statistically significant correlation between the number of days before the fracture was casted and the length of time needed to achieve union (r=0.27, p=0.001). CONCLUSION: Non-displaced scaphoid waist fractures have a high healing rate with appropriate identification and immobilization. Follow-up CT scans to assess healing can identify union within a shorter time frame (~7 weeks) than previously reported in the literature.

AB - PURPOSE: To clarify if blood loss and transfusion requirements can be decreased in revision knee surgery through a multimodal blood loss approach with tranexamic acid (TXA). PATIENTS AND METHODS: A retrospective study was designed in 87 knees (79 patients) that received a knee revision between 2007 and 2013. To avoid heterogeneity in the surgical technique, only revisions with one single implant system were included. A treatment series of 44 knees that received TXA and other techniques in a multimodal blood loss protocol was compared to a control series of 43 knees that received neither TXA nor the rest of the multimodal blood loss protocol. No differences in the complexity of surgeries or case severity were detected. RESULTS: A significant decrease was observed from 58% transfusion rate in the control group to 5% in the treated group. The postoperative haemoglobin drop was also significantly different. Although the use of a blood loss prevention approach including TXA was the most relevant factor in the transfusion risk (OR=15), longer surgical time also associated an increased risk of transfusion (OR=1.15). CONCLUSION: This study supports the use of a two-dose intravenous TXA under a multimodal blood loss prevention approach in revision knee replacement with significant reduction in the transfusion rate, postoperative blood loss and haemoglobin drop. PMID- 27708741 TI - The Rule of Histology in the Diagnosis of Periprosthetic Infection: Specific Granulocyte Counting Methods and New Immunohistologic Staining Techniques may Increase the Diagnostic Value. AB - OBJECTIVE: The current study investigates the diagnostic accuracy of the criteria described for frozen sections and whether modern leukocyte specific staining techniques including leukocyte peroxidase and Naphtol-AS-D-chloroacetate-esterase will improve the accuracy of the intra-operative histology. METHOD: 77 patients undergoing revision total hip and knee arthroplasty were included in this retrospective study. Patients were grouped into septic and aseptic based on intraoperative cultures. Tissue samples were analyzed utilizing the Mirra, Feldman, Lonner, Banit and Athanasou criteria. RESULTS: An experienced pathologist had a high specificity (96%), but rather low sensitivity (57%) diagnosing infection. By using the Banit-, Mirra-, or Athanasou-criteria the sensitivity is increased to 0.90. The Feldman- and Lonner-criteria have a lower sensitivity (0.48 and 0.38), however, an increased specificity of 0.96 and 0.98, respectively. The Banit cut off has the highest accuracy (86%). MPOX and NACE staining increased the sensitivity and accuracy up to 100% and 92% respectively. CONCLUSION: Banit's cut off is the most accurate histologic criteria to diagnose infection. Modern leukocyte specific staining techniques slightly improve the accuracy. The synovial fluid white blood cell count appears to be the most accurate intraoperative test.

AB - Nigrosphaerin A, a new isochromene derivative (1), was isolated from the endophytic fungus Nigrospora sphaerica and chemically identified as 3-(3,4 dihydroxyphenyl)-4,6,8-trihydroxy-1H-isochromen-1-one-6-O-beta-d-glucopyranoside. In addition nineteen known compounds (2-20) were isolated from the same fungus and chemically identified. Compounds (1-3, 5, and 7-16) were isolated for the first time from this fungus. In vitro antileukemic, antileishmanial, antifungal, antibacterial and antimalarial activities of (1-20) were examined. Compounds 5, 7, 9 and 10 showed good antileukemic activity against HL60 cells with IC50 values of 0.03, 0.39, 0.2 and 0.4 MUg/mL, respectively and against K562 cells with IC50 values of 0.35, 0.35, 0.49 and 0.01 MUg/mL, respectively. Compounds 3, 4 and 6 showed moderate antileishmanial activity with IC50 values of 30.2, 26.4 and 36.4 MUg/ml, respectively. Compound 7 showed moderate antifungal activity against Cryptococcus neoformans with IC50 value of 14.8 MUg/mL.

AB - Providers are expressing a desire for more efficient ways to retrieve relevant clinical data from the Electronic Health Record. In an effort to improve our Electromyography and Nerve Conduction Study reports, we surveyed referring providers on the effects of having the IMPRESSION at the start of the report. Our survey respondents felt that using this format for an Electromyography and Nerve Conduction Study report significantly improved the quality of the report while saving them time and/or mouse clicks when interpreting the report. Electro diagnosticians might consider using this format for their Electromyography and Nerve Conduction Study reports to improve referring provider satisfaction. PMID- 27708745 TI - Sex Differences in Gamma Band Functional Connectivity Between the Frontal Lobe and Cortical Areas During an Auditory Oddball Task, as Revealed by Imaginary Coherence Assessment. AB - We studied sex-related differences in gamma oscillation during an auditory oddball task, using magnetoencephalography and electroencephalography assessment of imaginary coherence (IC). We obtained a statistical source map of event related desynchronization (ERD) / event-related synchronization (ERS), and compared females and males regarding ERD / ERS. Based on the results, we chose respectively seed regions for IC determinations in low (30-50 Hz), mid (50-100 Hz) and high gamma (100-150 Hz) bands. In males, ERD was increased in the left posterior cingulate cortex (CGp) at 500 ms in the low gamma band, and in the right caudal anterior cingulate cortex (cACC) at 125 ms in the mid-gamma band. ERS was increased in the left rostral anterior cingulate cortex (rACC) at 375 ms in the high gamma band. We chose the CGp, cACC and rACC as seeds, and examined IC between the seed and certain target regions using the IC map. IC changes depended on the height of the gamma frequency and the time window in the gamma band. Although IC in the mid and high gamma bands did not show sex-specific differences, IC at 30-50 Hz in males was increased between the left rACC and the frontal, orbitofrontal, inferior temporal and fusiform target regions. Increased IC in males suggested that males may acomplish the task constructively, analysingly, emotionally, and by perfoming analysis, and that information processing was more complicated in the cortico-cortical circuit. On the other hand, females showed few differences in IC. Females planned the task with general attention and economical well-balanced processing, which was explained by the higher overall functional cortical connectivity. CGp, cACC and rACC were involved in sex differences in information processing and were likely related to differences in neuroanatomy, hormones and neurotransmitter systems. PMID- 27708746 TI - Associations and Trends in Cause-Specific Rates of Death Among Persons Reported with HIV Infection, 23 U.S. Jurisdictions, Through 2011. AB - BACKGROUND: Published death rates for persons with HIV have not distinguished deaths due to HIV from deaths due to other causes. Cause-specific death rates would allow better assessment of care needs. METHODS: Using data reported to the US national HIV surveillance system, we examined a) associations between selected decedent characteristics and causes of death during 2007-2011, b) trends in rates of death due to underlying causes among persons with AIDS during 1990-2011, and among all persons with diagnosed HIV infection (with or without AIDS) during 2000 2011. RESULTS: During 2007-2011, non-HIV-attributable causes of death with the highest rates per 1,000 person-years were heart disease (2.0), non-AIDS cancers other than lung cancer (1.4), and accidents (0.8). During 1990-2011, among persons with AIDS, the annual rate of death due to HIV-attributable causes decreased by 89% (from 122.0 to 13.2), and the rate due to non-HIV-attributable causes decreased by 57% (from 20.0 to 8.6), while the percentage of deaths caused by non-HIV-attributable causes increased from 11% to 43%. During 2000-2011, among persons with HIV infection, the rate of death due to HIV-attributable causes decreased by 69% (from 26.4 to 8.3), and the rate due to non-HIV-attributable causes decreased by 28% (from 10.5 to 7.6), while the percentage of deaths caused by non-HIV-attributable causes increased from 25% to 48%. CONCLUSION: Among HIV infected persons, as rates of death due to HIV-attributable causes decreased, rates due to non-HIV-attributable causes also decreased, but the percentages of deaths due to non-HIV-attributable causes, such as heart disease and non-AIDS cancers increased. PMID- 27708747 TI - Influence of the First Consultation on Adherence to Antiretroviral Therapy for HIV-infected Patients. AB - BACKGROUND: Physician attitude influences the way patients cope with diagnosis and therapy in chronic severe diseases such as cancer. Previous studies showed that such an effect exists in HIV care; it is likely that it begins with the first contact with a physician. OBJECTIVE: We aimed to explore in HIV-infected persons their perception of the first consultation they had with an HIV specialist (PFC-H), and whether this perception correlates with adherence to antiretroviral therapy. METHOD: The study was conducted in Grenoble University Hospital, France, a tertiary care center. Every antiretroviral-experienced patient was asked to freely complete a self-reported, anonymous questionnaire concerning retrospective PFC-H, present adherence (Morisky scale), and present perceptions and beliefs about medicine (BMQ scale). RESULTS: One hundred and fifty-one questionnaires were available for evaluation. PFC-H score and adherence were correlated, independently from age, gender, and numbers of pill(s) and of pill intake(s) per day. BMQ score also correlated with adherence; structural equation analysis suggested that the effect of PFC-H on adherence is mediated by positive beliefs. CONCLUSION: These results suggest that for HIV-infected persons, the perceptions remaining from the first consultation with an HIV specialist physician influence important issues such as adherence and perception about medicine. Physicians must be aware of this potentially long-lasting effect. PMID- 27708748 TI - Prevalence of the CHEK2 R95* germline mutation. AB - BACKGROUND: While germline CHEK2 mutations have been linked to a moderately elevated cancer risk, to date, a limited number of such mutations have been identified. Recently, we reported a germline nonsense mutation (C283T; R95*), introducing an early stop-codon, in two Norwegian patients diagnosed with locally advanced breast cancer. Both patients were resistant to anthracycline therapy, resembling what has been observed for TP53 mutations. METHODS: In the present study, we screened a large population based sample, including 3748 non-cancer individuals and 7081 incident cancer cases (breast cancer, n = 1717; prostate cancer n = 2501, lung cancer n = 1331 and colorectal cancer n = 1532), for the distribution of CHEK2 R95*. RESULTS: We found that 12 individuals (0.11 %) carried the R95* variant: 4 non-cancer individuals (0.11 %), 4 breast cancer cases (0.23 %), and 4 prostate cancer cases (0.16 %). Although the low number of observations precluded formal statistical assessment, our data may indicate an elevated risk for breast (OR: 2.19, 95 % CI: 0.55-8.75) and prostate cancer (OR: 1.5, 95 % CI: 0.36-6.00) associated with CHEK2 R95*. By mining international databanks, we found no individuals carrying the R95* mutation, indicating it to be restricted to the Norwegian population. CONCLUSION: We provide proof-of concept that previously unknown CHEK2 germline mutations may be present in certain populations. Notably, germline mutations in tumours are in general missed by contemporary massive parallel sequencing strategies, since tumour mutations are usually filtered against the germline. The fact that the CHEK2 R95* mutation may be associated with resistance to anthracyclines in cancer patients emphasizes its possible clinical importance. PMID- 27708749 TI - Permanent draft genome of Thermithiobaclillus tepidarius DSM 3134T, a moderately thermophilic, obligately chemolithoautotrophic member of the Acidithiobacillia. AB - Thermithiobacillus tepidarius DSM 3134T was originally isolated (1983) from the waters of a sulfidic spring entering the Roman Baths (Temple of Sulis-Minerva) at Bath, United Kingdom and is an obligate chemolithoautotroph growing at the expense of reduced sulfur species. This strain has a genome size of 2,958,498 bp. Here we report the genome sequence, annotation and characteristics. The genome comprises 2,902 protein coding and 66 RNA coding genes. Genes responsible for the transaldolase variant of the Calvin-Benson-Bassham cycle were identified along with a biosynthetic horseshoe in lieu of Krebs' cycle sensu stricto. Terminal oxidases were identified, viz. cytochrome c oxidase (cbb3, EC 1.9.3.1) and ubiquinol oxidase (bd, EC 1.10.3.10). Metalloresistance genes involved in pathways of arsenic and cadmium resistance were found. Evidence of horizontal gene transfer accounting for 5.9 % of the protein-coding genes was found, including transfer from Thiobacillus spp. and Methylococcus capsulatus Bath, isolated from the same spring. A sox gene cluster was found, similar in structure to those from other Acidithiobacillia - by comparison with Thiobacillus thioparus and Paracoccus denitrificans, an additional gene between soxA and soxB was found, annotated as a DUF302-family protein of unknown function. As the Kelly-Friedrich pathway of thiosulfate oxidation (encoded by sox) is not used in Thermithiobacillus spp., the role of the operon (if any) in this species remains unknown. We speculate that DUF302 and sox genes may have a role in periplasmic trithionate oxidation. PMID- 27708750 TI - Classification and substrate head-group specificity of membrane fatty acid desaturases. AB - Membrane fatty acid desaturases are a diverse superfamily of enzymes that catalyze the introduction of double bonds into fatty acids. They are essential in a range of metabolic processes, such as the production of omega-3 fatty acids. However, our structure-function understanding of this superfamily is still developing and their range of activities and substrate specificities are broad, and often overlapping, which has made their systematic characterization challenging. A central issue with characterizing these proteins has been the lack of a structural model, which has been overcome with the recent publication of the crystal structures of two mammalian fatty acid desaturases. In this work, we have used sequence similarity networks to investigate the similarity among over 5000 related membrane fatty acid desaturase sequences, leading to a detailed classification of the superfamily, families and subfamilies with regard to their function and substrate head-group specificity. This work will facilitate rapid prediction of the function and specificity of new and existing sequences, as well as forming a basis for future efforts to manipulate the substrate specificity of these proteins for biotechnology applications. PMID- 27708751 TI - Dual mode of cell death upon the photo-irradiation of a RuII polypyridyl complex in interphase or mitosis. AB - Photodynamic therapy (PDT) is an attractive, complementary medical technique to chemotherapy. Among the different photosensitizers (PSs) employed, Ru(ii) polypyridyl complexes were found to be valid substitutes to porphyrin-based or phthalocyanine-based PSs. Here, we confirm that one such complex, namely [Ru(bipy)2-dppz-7-methoxy][PF6]2 (Ru65), which localizes in the nucleus of various cancer and normal cells, displays cytotoxicity only upon UV-A irradiation. Importantly, we disclose the molecular mechanism of the UV-A mediated cytotoxic action of Ru65. We demonstrate that Ru65 intercalates in DNA and, upon light irradiation, promotes guanine oxidation, resulting in nicks in the double helix. We confirm this mechanism of action in living cells, showing that the UV-A irradiation of cells loaded with Ru65 results in a transient DNA damage response and cell death. Strikingly, the photo-irradiation of Ru65 triggered distinct mechanisms of cell death in interphase or mitotic cells. The former underwent cell cycle arrest at the G2/M phase and massive cytoplasmic vacuolation, which was paralleled by an unfolded-protein stress response, resulting in a reduction of viability and cell death through a paraptosis-like mechanism. On the other hand, the UV-A irradiation of Ru65 in cells synchronized by G2/M block-release with a selective CDK1 inhibitor led to blocking mitotic entry and rapid cell death through classic apoptotic pathways. Importantly, targeting mitotic cells with Ru65 allowed increasing its photo-toxicity by a factor of 3.6. Overall, our findings show that the use of a combination of a cell cycle inhibitor and a PS targeting the nucleus could open up new avenues in PDT. PMID- 27708752 TI - Using Single Colors and Color Pairs to Communicate Basic Tastes II: Foreground Background Color Combinations. AB - People associate basic tastes (e.g., sweet, sour, bitter, and salty) with specific colors (e.g., pink or red, green or yellow, black or purple, and white or blue). In the present study, we investigated whether a color bordered by another color (either the same or different) would give rise to stronger taste associations relative to a single patch of color. We replicate previous findings, highlighting the existence of a robust crossmodal correspondence between individual colors and basic tastes. On occasion, color pairs were found to communicate taste expectations more consistently than were single color patches. Furthermore, and in contrast to a recent study in which the color pairs were shown side-by-side, participants took no longer to match the color pairs with tastes than the single colors (they had taken twice as long to respond to the color pairs in the previous study). Possible reasons for these results are discussed, and potential applications for the results, and for the testing methodology developed, are outlined. PMID- 27708753 TI - How Heavy Is an Illusory Length? AB - The perception of object properties, such as size and weight, can be subject to illusions. Could a visual size illusion influence perceived weight? Here, we tested whether the size-weight illusion occurs when lifting two physically identical but perceptually different objects, by using an illusion of size. Participants judged the weight and length of 11 to 17 cm brass bars with equal density to which cardboard arrowheads were attached to create a Muller-Lyer illusion. We found that these stimuli induced an illusion in which the bar that was visually perceived as being shorter was also perceived as feeling heavier. In fact, a 5-mm increase in illusory length corresponded to a decrease in illusory weight of 15 g. PMID- 27708754 TI - Apparent Biological Motion in First and Third Person Perspective. AB - Apparent biological motion is the perception of plausible movements when two alternating images depicting the initial and final phase of an action are presented at specific stimulus onset asynchronies. Here, we show lower subjective apparent biological motion perception when actions are observed from a first relative to a third visual perspective. These findings are discussed within the context of sensorimotor contributions to body ownership. PMID- 27708755 TI - The Anne Boleyn Illusion is a Six-Fingered Salute to Sensory Remapping. AB - The Anne Boleyn Illusion exploits the somatotopic representation of touch to create the illusion of an extra digit and demonstrates the instantaneous remapping of relative touch location into body-based coordinates through visuo tactile integration. Performed successfully on thousands, it is also a simple demonstration of the flexibility of body representations for use at public events, in schools or in the home and can be implemented anywhere by anyone with a mirror and some degree of bimanual coordination. PMID- 27708756 TI - Plasticity and regeneration of gonads in the annelid Pristina leidyi. AB - BACKGROUND: Gonads are specialized gamete-producing structures that, despite their functional importance, are generated by diverse mechanisms across groups of animals and can be among the most plastic organs of the body. Annelids, the segmented worms, are a group in which gonads have been documented to be plastic and to be able to regenerate, but little is known about what factors influence gonad development or how these structures regenerate. In this study, we aimed to identify factors that influence the presence and size of gonads and to investigate gonad regeneration in the small asexually reproducing annelid, Pristina leidyi. RESULTS: We found that gonad presence and size in asexual adult P. leidyi are highly variable across individuals and identified several factors that influence these structures. An extrinsic factor, food availability, and two intrinsic factors, individual age and parental age, strongly influence the presence and size of gonads in P. leidyi. We also found that following head amputation in this species, gonads can develop by morphallactic regeneration in previously non-gonadal segments. We also identified a sexually mature individual from our laboratory culture that demonstrates that, although our laboratory strain reproduces only asexually, it retains the potential to become fully sexual. CONCLUSIONS: Our findings demonstrate that gonads in P. leidyi display high phenotypic plasticity and flexibility with respect to their presence, their size, and the segments in which they can form. Considering our findings along with relevant data from other species, we find that, as a group, clitellate annelids can form gonads in at least four different contexts: post-starvation refeeding, fission, morphallactic regeneration, and epimorphic regeneration. This group is thus particularly useful for investigating the mechanisms involved in gonad formation and the evolution of post-embryonic phenotypic plasticity. PMID- 27708758 TI - Quantifying cellular and subcellular stretches in embryonic lung epithelia under peristalsis: where to look for mechanosensing. AB - Peristalsis begins in the lung as soon as the smooth muscle (SM) forms, and persists until birth. As the prenatal lung is filled with liquid, SM action can, through lumen pressure, deform tissues far from the immediately adjacent tissues. Stretching of embryonic tissues has been shown to have potent morphogenetic effects. We hypothesize that these effects are at work in lung morphogenesis. In order to refine that broad hypothesis in a quantitative framework, we geometrically analyse cell shapes in an epithelial tissue, and individual cell deformations resulting from peristaltic waves that completely occlude the airway. Typical distortions can be very large, with opposite orientations in the stalk and tip regions. Apical distortions are always greater than basal distortions. We give a quantitative estimate of the relationship between length of occluded airway and the resulting tissue stretch in the distal tip. We refine our analysis of cell stresses and strains from peristalsis with a simple mechanical model of deformation of cells within an epithelium, which accounts for basic subcellular geometry and material properties. The model identifies likely stress concentrations near the nucleus and at the apical cell-cell junction. The surprisingly large strains of airway peristalsis may serve to rearrange cells and stimulate other mechanosensitive processes by repeatedly aligning cytoskeletal components and/or breaking and reforming lateral cell-cell adhesions. Stress concentrations between nuclei of adjacent cells may serve as a mechanical control mechanism guiding the alignment of nuclei as an epithelium matures. PMID- 27708757 TI - Measuring cellular traction forces on non-planar substrates. AB - Animal cells use traction forces to sense the mechanics and geometry of their environment. Measuring these traction forces requires a workflow combining cell experiments, image processing and force reconstruction based on elasticity theory. Such procedures have already been established mainly for planar substrates, in which case one can use the Green's function formalism. Here we introduce a workflow to measure traction forces of cardiac myofibroblasts on non planar elastic substrates. Soft elastic substrates with a wave-like topology were micromoulded from polydimethylsiloxane and fluorescent marker beads were distributed homogeneously in the substrate. Using feature vector-based tracking of these marker beads, we first constructed a hexahedral mesh for the substrate. We then solved the direct elastic boundary volume problem on this mesh using the finite-element method. Using data simulations, we show that the traction forces can be reconstructed from the substrate deformations by solving the corresponding inverse problem with an L1-norm for the residue and an L2-norm for a zeroth-order Tikhonov regularization. Applying this procedure to the experimental data, we find that cardiac myofibroblast cells tend to align both their shapes and their forces with the long axis of the deformable wavy substrate. PMID- 27708760 TI - Local modulation of chemoattractant concentrations by single cells: dissection using a bulk-surface computational model. AB - Chemoattractant gradients are usually considered in terms of sources and sinks that are independent of the chemotactic cell. However, recent interest has focused on 'self-generated' gradients, in which cell populations create their own local gradients as they move. Here, we consider the interplay between chemoattractants and single cells. To achieve this, we extend a recently developed computational model to incorporate breakdown of extracellular attractants by membrane-bound enzymes. Model equations are parametrized, using the published estimates from Dictyostelium cells chemotaxing towards cyclic AMP. We find that individual cells can substantially modulate their local attractant field under physiologically appropriate conditions of attractant and enzymes. This means the attractant concentration perceived by receptors can be a small fraction of the ambient concentration. This allows efficient chemotaxis in chemoattractant concentrations that would be saturating without local breakdown. Similar interactions in which cells locally mould a stimulus could function in many types of directed cell motility, including haptotaxis, durotaxis and even electrotaxis. PMID- 27708759 TI - A mathematical model of GTPase pattern formation during single-cell wound repair. AB - Rho GTPases are regulatory proteins whose patterns on the surface of a cell affect cell polarization, cell motility and repair of single-cell wounds. The stereotypical patterns formed by two such proteins, Rho and Cdc42, around laser injured frog oocytes permit experimental analysis of GTPase activation, inactivation, segregation and crosstalk. Here, we review the development and analysis of a spatial model of GTPase dynamics that describe the formation of concentric zones of Rho and Cdc42 activity around wounds, and describe how this model has provided insights into the roles of the GTPase effector molecules protein kinase C (PKCbeta and PKCeta) and guanosine nucleotide dissociation inhibitor (GDI) in the wound response. We further demonstrate how the use of a 'sharp switch' model approximation in combination with bifurcation analysis can aid mapping the model behaviour in parameter space (approximate results confirmed with numerical simulation methods). Using these methods in combination with experimental manipulation of PKC activity (PKC overexpression (OE) and dominant negative conditions), we have shown that: (i) PKCbeta most probably acts by enhancing existing positive feedbacks (from Rho to itself via the guanosine nucleotide exchange factor domain of Abr, and from Cdc42 to itself), (ii) PKCeta most probably increases basal rates of inactivation (or possibly decreases basal rates of activation) of Rho and Cdc42, and (iii) the graded distribution of PKCeta and its effect on initial Rho activity accounts for inversion of zones in a fraction (20%) of PKCeta OE cells. Finally, we speculate that GDIs (which sequester GTPases) may have a critical role in defining the spatial domain, where the wound response may occur. This paper provides a more thorough exposition of the methods of analysis used in the investigation, whereas previous work on this topic was addressed to biologists and abbreviated such discussion. PMID- 27708761 TI - Collective migration under hydrodynamic interactions: a computational approach. AB - We consider a generic model for cell motility. Even if a comprehensive understanding of cell motility remains elusive, progress has been achieved in its modelling using a whole-cell physical model. The model takes into account the main mechanisms of cell motility, actin polymerization, actin-myosin dynamics and substrate mediated adhesion (if applicable), and combines them with steric cell cell and hydrodynamic interactions. The model predicts the onset of collective cell migration, which emerges spontaneously as a result of inelastic collisions of neighbouring cells. Each cell here modelled as an active polar gel is accomplished with two vortices if it moves. Upon collision of two cells, the two vortices which come close to each other annihilate. This leads to a rotation of the cells and together with the deformation and the reorientation of the actin filaments in each cell induces alignment of these cells and leads to persistent translational collective migration. The effect for low Reynolds numbers is as strong as in the non-hydrodynamic model, but it decreases with increasing Reynolds number. PMID- 27708762 TI - Review on experiment-based two- and three-dimensional models for wound healing. AB - Traumatic and chronic wounds are a considerable medical challenge that affects many populations and their treatment is a monetary and time-consuming burden in an ageing society to the medical systems. Because wounds are very common and their treatment is so costly, approaches to reveal the responses of a specific wound type to different medical procedures and treatments could accelerate healing and reduce patient suffering. The effects of treatments can be forecast using mathematical modelling that has the predictive power to quantify the effects of induced changes to the wound-healing process. Wound healing involves a diverse and complex combination of biophysical and biomechanical processes. We review a wide variety of contemporary approaches of mathematical modelling of gap closure and wound-healing-related processes, such as angiogenesis. We provide examples of the understanding and insights that may be garnered using those models, and how those relate to experimental evidence. Mathematical modelling based simulations can provide an important visualization tool that can be used for illustrational purposes for physicians, patients and researchers. PMID- 27708763 TI - Multimodality imaging and mathematical modelling of drug delivery to glioblastomas. AB - Patients diagnosed with glioblastoma, an aggressive brain tumour, have a poor prognosis, with a median overall survival of less than 15 months. Vasculature within these tumours is typically abnormal, with increased tortuosity, dilation and disorganization, and they typically exhibit a disrupted blood-brain barrier (BBB). Although it has been hypothesized that the 'normalization' of the vasculature resulting from anti-angiogenic therapies could improve drug delivery through improved blood flow, there is also evidence that suggests that the restoration of BBB integrity might limit the delivery of therapeutic agents and hence their effectiveness. In this paper, we apply mathematical models of blood flow, vascular permeability and diffusion within the tumour microenvironment to investigate the effect of these competing factors on drug delivery. Preliminary results from the modelling indicate that all three physiological parameters investigated-flow rate, vessel permeability and tissue diffusion coefficient interact nonlinearly to produce the observed average drug concentration in the microenvironment. PMID- 27708764 TI - Comparison of cell migration mechanical strategies in three-dimensional matrices: a computational study. AB - Cell migration on a two-dimensional flat surface has been extensively studied and is generally characterized by a front-protrusion-rear-contraction process. In a three-dimensional (3D) environment, on the other hand, cells adopt multiple migration strategies depending on the cell type and the properties of the extracellular matrix (ECM). By using computer simulations, we find that these migration strategies can be classified by various spatial-temporal dynamics of actin protrusion, actin-myosin contraction and actin-ECM adhesion. We demonstrate that if we include or exclude proteolysis of ECM, and vary adhesion dynamics and spatial distributions of protrusion, contraction and adhesion, our model can reproduce six experimentally observed motility modes: mesenchymal, chimneying, amoeboid, blebbing, finger-like protrusion and rear-squeezing cell locomotory behaviours. We further find that the mode of the cell motility evolves in response to the ECM density and adhesion detachment rate. The model makes non trivial predictions about cell speed as a function of the adhesion strength, and ECM elasticity and mesh size. PMID- 27708765 TI - Prediction of traction forces of motile cells. AB - When crawling on a flat substrate, living cells exert forces on it via adhesive contacts, enabling them to build up tension within their cytoskeleton and to change shape. The measurement of these forces has been made possible by traction force microscopy (TFM), a technique which has allowed us to obtain time-resolved traction force maps during cell migration. This cell 'footprint' is, however, not sufficient to understand the details of the mechanics of migration, that is how cytoskeletal elements (respectively, adhesion complexes) are put under tension and reinforce or deform (respectively, mature and/or unbind) as a result. In a recent paper, we have validated a rheological model of actomyosin linking tension, deformation and myosin activity. Here, we complement this model with tentative models of the mechanics of adhesion and explore how closely these models can predict the traction forces that we recover from experimental measurements during cell migration. The resulting mathematical problem is a PDE set on the experimentally observed domain, which we solve using a finite-element approach. The four parameters of the model can then be adjusted by comparison with experimental results on a single frame of an experiment, and then used to test the predictive power of the model for following frames and other experiments. It is found that the basic pattern of traction forces is robustly predicted by the model and fixed parameters as a function of current geometry only. PMID- 27708766 TI - Hybrid vertex-midline modelling of elongated plant organs. AB - We describe a method for the simulation of the growth of elongated plant organs, such as seedling roots. By combining a midline representation of the organ on a tissue scale and a vertex-based representation on the cell scale, we obtain a multiscale method, which is able to both simulate organ growth and incorporate cell-scale processes. Equations for the evolution of the midline are obtained, which depend on the cell-wall properties of individual cells through appropriate averages over the vertex-based representation. The evolution of the organ midline is used to deform the cellular-scale representation. This permits the investigation of the regulation of organ growth through the cell-scale transport of the plant hormone auxin. The utility of this method is demonstrated in simulating the early stages of the response of a root to gravity, using a vertex based template acquired from confocal imaging. Asymmetries in the concentrations of auxin between the upper and lower sides of the root lead to bending of the root midline, reflecting a gravitropic response.

AB - BACKGROUND: 3-Nitro-4-hydroxy phenyl arsenic acid, roxarsone, is widely used as an organic arsenic feed additive for livestock and poultry, which may increase the level of arsenic in the environment and the risk of exposure to arsenic in human. Little information is focused on the angiogenesis roxarsone-induced and its mechanism at present. This paper aims to study the role of PI3K/Akt signaling in roxarsone-induced angiogenesis in rat vascular endothelial cells and a mouse B16-F10 melanoma xenograft model. RESULTS: The results showed that treatment with 0.1-10.0 umol/L roxarsone resulted in an increase in the OD rate in the MTT assay, the number of BrdU-positive cells in the proliferation assay, the migration distance in the scratch test and the number of meshes in tube formation assay. Further, treatment with 1.0 umol/L roxarsone was associated with significantly higher phosphorylation of PI3K/Akt and expression of VEGF than the control treatment. The PI3K inhibitor was found to significantly combat the effects of 1.0 umol/L roxarsone. Furthermore, roxarsone treatment was observed to increase the weight and volume of B16-F10 xenografts and VEGF expression and PI3K/Akt phosphorylation in a dose-dependent manner, with the 25 mg/kg dose having significant effects. CONCLUSIONS: These results demonstrate that roxarsone has the ability to promote growth and tube formation in vascular endothelial cells and the growth of mouse B16-F10 xenografts. Further, the findings also indicate that PI3K/Akt signaling plays a regulatory role in roxarsone-induced angiogenesis in vivo and in vitro.

AB - Movement of cells and tissues is a basic biological process that is used in development, wound repair, the immune response to bacterial invasion, tumour formation and metastasis, and the search for food and mates. While some cell movement is random, directed movement stimulated by extracellular signals is our focus here. This involves a sequence of steps in which cells first detect extracellular chemical and/or mechanical signals via membrane receptors that activate signal transduction cascades and produce intracellular signals. These intracellular signals control the motile machinery of the cell and thereby determine the spatial localization of the sites of force generation needed to produce directed motion. Understanding how force generation within cells and mechanical interactions with their surroundings, including other cells, are controlled in space and time to produce cell-level movement is a major challenge, and involves many issues that are amenable to mathematical modelling. PMID- 27708769 TI - Does dental health of 6-year-olds reflect the reform of the Israeli dental care system? AB - BACKGROUND: The National health insurance law enacted in 1995 did not include dental care in its basket of services. Dental care for children was first included in 2010, initially up till 8 years of age. The eligibility age rose to 12 years in 2013. The dental survey of 6 year-olds in 2007 found that the average of decayed, missing and filled teeth index (dmft) was 3.31 and 35 % of children were caries free. The current cross sectional survey of dental health for 6 year olds was conducted as a comparison to the pre-reform status. METHODS: Twenty three local authorities were randomly selected nationwide. Two Grade 1 classes were randomly chosen in each. The city of Jerusalem was also included in the survey because of its size. The children were examined according to the WHO Oral Health Survey Methods 4th ed protocol. The dental caries index for deciduous teeth (dmft: decayed, missing, filled teeth) was calculated. RESULTS: One thousand two hundred ten children were examined. 61.7 % of the children suffered from dental decay and only 38.3 % were caries free. The mean dmft was 2.56; d = 1.41 (teeth with untreated caries), f = 1.15 (teeth damaged by decay and restored), virtually none were missing due to caries. Dental caries prevalence was rather consistent, an average of over 2 teeth affected per child. Although there is no major change in comparison to former surveys, there is more treated than untreated disease. In the present survey the f component is higher than in the past, especially in the Jewish sector where it is the main component. It is still lower in the Arab sector. CONCLUSIONS: Although the level of dental disease remained rather constant, an increase in the treatment component was observed. In order to reduce caries prevalence, preventive measures such as school dental services and drinking water fluoridation should be extended and continued. Primary preventive dental services should be established for children from birth, with an emphasis on primary health care and educational settings, such as family health centers and kindergartens. PMID- 27708770 TI - The cytotoxic mechanisms of disulfiram and copper(ii) in cancer cells. AB - The anticancer activity of disulfiram (DS) is copper(ii) (Cu)-dependent. This study investigated the anticancer mechanisms of DS/Cu using in vitro cytotoxicity and metabolic kinetic analysis. Our study indicates that DS/Cu targets cancer cells by the combination of two types of actions: (1) instant killing executed by DS/Cu reaction generated reactive oxygen species; (2) delayed cytotoxicity introduced by the end product, DDC-Cu. Nanoencapsulation of DS might shed light on repositioning of DS into cancer treatment. PMID- 27708771 TI - Decision making on helminths in cattle: diagnostics, economics and human behaviour. AB - Helminth infections of cattle affect productivity in all classes of stock, and are amongst the most important production-limiting diseases of grazing ruminants. Over the last decade, there has been a shift in focus in the diagnosis of these infections from merely detecting presence/absence of infection towards detecting its impact on production. This has been facilitated by studies observing consistent negative correlations between helminth diagnostic test results and measures of productivity. Veterinarians are increasingly challenged to consider the economic aspects of their work, and the use of these tests should now be integrated in economic evaluation frameworks for improved decision making. In this paper, we review recent insights in the farm-specific economic impact of helminth infections on dairy cattle farms as well as in farmer attitudes and behaviour regarding helminth control. Combining better economic impact assessments of helminth infections together with a deeper understanding of the non-economic factors that drive a farmer's animal health decisions should result in more effective control strategies and increased farmer satisfaction. PMID- 27708773 TI - Determination of basal ileal endogenous losses and standardized ileal digestibility of amino acids in barley fed to growing pigs. AB - BACKGROUND: Basal ileal endogenous amino acid (AA) losses (IAAend) and standardized ileal digestibility (SID) values of cereal grains, such as barley, are apparently underestimated when determined according to the nitrogen (N)-free method. Regression analysis between the dietary apparent ileal digestible content (cAID) and total crude protein (CP) and AA can be considered as alternative approach to obtain more accurate values for IAAend and SID of AA in cereal grains. METHODS: Eight hulled barley genotypes were used, with barley being the only source of CP and AA in the assay diets. The diets contained 95 % as-fed of these eight barley genotypes each, ranging in CP content between 109.1 and 123.8 g/kg dry matter (DM). Nine ileally T-cannulated barrows, average body weight (BW) 30 +/- 2 kg, were allotted to a row-column design comprising eight periods with 6 d each and nine pigs. On d 5 and the night of d 6 of every period, ileal digesta were collected for a total of 12 h. The IAAend and the SID were determined by linear regression analysis between cAID and total dietary CP and AA. RESULTS: There exist linear relationships between cAID and total CP and AA (P < 0.001). The IAAend of CP, Lys, Met, Thr and Trp amounted to 35.34, 1.08, 0.25, 1.02 and 0.38 g/kg DM intake (DMI), respectively, which are greater compared to average IAAend determined previously under N-free feeding conditions. The SID of CP, Lys, Met, Thr and Trp was 90, 79, 85, 79 and 86 %, respectively, and was greater when compared to tabulated values. Moreover, these SID values were greater than those reported in literature, based on correction of apparent ileal digestibility (AID) of CP and AA for their IAAend values. Summarized, the results of the present regression analysis indicate greater IAAend in barley-based diets compared to those obtained by N-free feeding. CONCLUSIONS: For low-protein feed ingredients like barley the regression method may be preferred over correction of AID values for their IAAend determined under N-free feeding conditions, as intercepts and slopes of the linear regression equations between cAID and total dietary CP and AA provide direct estimates of IAAend and SID of CP and AA in the presence of the assay feed ingredient. PMID- 27708772 TI - Single-cell intracellular nano-pH probes. AB - Within a large clonal population, such as cancerous tumor entities, cells are not identical, and the differences between intracellular pH levels of individual cells may be important indicators of heterogeneity that could be relevant in clinical practice, especially in personalized medicine. Therefore, the detection of the intracellular pH at the single-cell level is of great importance to identify and study outlier cells. However, quantitative and real-time measurements of the intracellular pH of individual cells within a cell population is challenging with existing technologies, and there is a need to engineer new methodologies. In this paper, we discuss the use of nanopipette technology to overcome the limitations of intracellular pH measurements at the single-cell level. We have developed a nano-pH probe through physisorption of chitosan onto hydroxylated quartz nanopipettes with extremely small pore sizes (~100 nm). The dynamic pH range of the nano-pH probe was from 2.6 to 10.7 with a sensitivity of 0.09 units. We have performed single-cell intracellular pH measurements using non cancerous and cancerous cell lines, including human fibroblasts, HeLa, MDA-MB-231 and MCF-7, with the pH nanoprobe. We have further demonstrated the real-time continuous single-cell pH measurement capability of the sensor, showing the cellular pH response to pharmaceutical manipulations. These findings suggest that the chitosan-functionalized nanopore is a powerful nano-tool for pH sensing at the single-cell level with high temporal and spatial resolution. PMID- 27708775 TI - Incidence of sickness absence by type of employment contract: one year follow-up study in Spanish salaried workers. AB - BACKGROUND: To examine the differences in the incidence of registered sickness absence by type of employment contract in a large representative sample of salaried workers in Spain in 2009. METHOD: A study of 653,264 salaried workers covered by the Social Security system who had 133,724 sickness absence episodes in 2009. Crude and adjusted rate ratios and their corresponding 95 % confidence intervals (CIs) were calculated with Poisson regression models. RESULTS: The incidence rate per 100 workers-year of sickness absence for temporary workers (IR = 32.2) was slightly higher than that of permanent workers (IR = 28.9). This pattern was observed in both men (RR = 1.12; 95 % CI 1.10-1.14) and women (RR 1.11; 95 % CI 1.09-1.12). However, after adjusting for age, company size, and occupational category, the differences disappeared in men (aRR = 1.01; 95 % CI 0.99-1.02) and decreased in women (aRR = 1.06; 95 % CI 1.04-1.07). CONCLUSION: Our findings provide evidence on the independence of sickness absence benefits from the type of employment contract as well as on the nonexistence of incentives for taking sickness absence in workers with a permanent employment contract. In the context of increasing market flexibility, these results show a positive functioning of the Social Security system. PMID- 27708774 TI - Effects of chronic heat stress on granulosa cell apoptosis and follicular atresia in mouse ovary. AB - BACKGROUND: Heat stress is known to alter follicular dynamics and granulosa cell function and may contribute to the diminished reproductive efficiency commonly observed in mammals during the summer. Although several investigators have studied heat-induced ovarian injury, few reports have focused on the effects of chronic heat stress on ovarian function and the molecular mechanisms through which it induces ovarian injury. METHODS: In Exp. 1, 48 female mice were assigned to a control or heat-stressed treatment. After exposure to a constant temperature of 25 degrees C for 7, 14, 21 or 28 d (n = 6) or to 42 degrees C for 3 h per d for 7, 14, 21 or 28 d (n = 6), the mice were euthanized and their ovaries were analyzed for follicular atresia, granulosa cell apoptosis, changes in the abundance of HSP70 protein and serum concentrations of estradiol. In Exp. 2, the expression of HSP70 and aromatase was quantified in antral follicles cultured in vitro at 37 or 42 degrees C for 24 h. In Exp. 3, granulosa cells from ovaries maintained at 37 or 41 degrees C for 2 h were analyzed for their expression of HSP70, Bim, caspase-3 and cleaved caspase-3. RESULTS: In Exp. 1, body weight and food intake of heat-stressed mice decreased (P < 0.05) compared with control mice while the concentration of estradiol in serum was lower (P < 0.05) in heat stressed mice than in control mice. Compared with control mice, the percentage of atretic follicles and the number of antral follicles with severe apoptotic signals were increased (P < 0.05) after 21 d of heat-stressed treatment. HSP70 protein was more abundant (P < 0.05) in heat-stressed mice than control mice. In Exp. 2, heat stress increased HSP70 and decreased aromatase proteins (P < 0.05) in antral follicles. In Exp. 3, TUNEL-positive granulosa cells from heat-stressed ovaries were observed concomitant with a significant increase in HSP70, Bim and cleaved caspase-3 protein. CONCLUSION: Heat-stress in mice decrease estradiol in serum and aromatase in antral follicles but increased number of atretic follicles and granulosa cell undergoing apoptosis which may explain the decreased fertility commonly observed in heat-stressed animals. PMID- 27708776 TI - Implementing Smarter Lunchrooms Makeovers in New York state middle schools: an initial process evaluation. AB - BACKGROUND: This paper presents design and findings from the process evaluation of a randomized controlled trial (RCT) testing the effectiveness of Smarter Lunchrooms Movement (SLM) interventions to encourage consumption of either fruit, vegetables, or unflavored milk in middle school cafeterias (grades 6-8, typically children ages 10-14 years). Using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework adapted for environmental interventions, the process evaluation monitored fidelity to SLM protocol, determined barriers and facilitators influencing fidelity, and identified the training and support needs of implementers. METHODS: Under research team guidance, community partners (interventionists) assisted school food service staff (providers) with a six week implementation of protocol items in 13 public middle school cafeterias (two milk treatment, three vegetable treatment, four fruit treatment, and four control) in New York State during the 2013-2014 academic year. Process evaluation measures included semi-quantitative measures of implementation and maintenance (lunchroom audits) and qualitative data (environmental assessments and semi-structured interviews with school food service staff). Analyses identified challenges and opportunities for improving intervention delivery. RESULTS: Approximately 75 % of enrolled students participated in school lunch programs and thus were exposed to the SLM intervention. Findings indicated potential contamination by other nutrition related activities in the lunchroom and larger school environment may have affected the intervention impact. Modest implementation fidelity scores were observed for intervention treatments. Providers reported treatments were acceptable and feasible, however interventionists confirmed motivation and perceived effectiveness varied among schools. Post-intervention audits revealed limited maintenance of intervention protocols. Strategies to enhance buy-in and communication among providers and increased interventionist support are recommended. CONCLUSIONS: RE-AIM was a valuable framework for this process evaluation. Results highlighted implementation barriers and facilitators, and findings will enhance interpretation of forthcoming outcome data. Results will inform future iterations of the SLM RCT and provide valuable insights for those designing environmental interventions in school cafeterias. PMID- 27708778 TI - Getting to grips with the obesity epidemic in Europe. AB - Obesity is a global epidemic. It is responsible for increased patient morbidity and mortality. Significant related pathologies including diabetes mellitus compound the overall risks. Obesity is a significant financial burden. This includes direct and indirect medical costs, amounting to millions of euros each year. Multiple European studies have outlined a steady incline in obesity prevalence rates. Tackling obesity is no easy task. Policy makers aiming to reduce obesity rates should adopt an evidence-based approach. This entails adopting both micro- and macro-interventions tweaked to each country's individual requirements. The ideal way forward would be to tackle obesity from the individual, population-wide and food industry angles. The key towards a successful intervention is for each country to carry out well-planned health examination studies, in an attempt to pin point local risk factors. Having a correct individualized picture, each country can move forward and draw policies and interventional procedures. The aim should be to primarily improve the quality of life. Second, the country's capital expenditure is also reduced. PMID- 27708777 TI - Cough: impact, beliefs, and expectations from a national survey. AB - BACKGROUND: Cough is one of the most common discomforts affecting general population, which can disrupt subjects' quality of life due to its physical, social, and psychological effects. Aim of the study was to investigate the impact of cough and related beliefs of general population. METHODS: A cross-sectional telephone survey was carried out by means of a specific, validated questionnaire on a representative sample of Italian general population. All the interviews were carried out according to the Computer Assisted Telephone Interview (CATI) methodology by expert, professional interviewers. Distributions of all answers were calculated in the overall sample. RESULTS: A total of 1,251 subjects (mean age: 49 years; females 44.2 %) completed the interviews. The overall number of telephone calls was 5362, and the corresponding redemption rate was 1/4.3 (23.%). The sample was representative of national population in terms of geographical distribution, age, gender, and smoking habit. The majority of respondents was convinced that cough is merely a symptom of several different diseases, but 46.4 % of respondents affirmed that cough should be regarded as "a disease" per se. Only 29.1 % of subjects say that they usually do not complain of any cough over the year, while 18.4 % reported >= 3 episodes of cough/year. These episodes have a duration ranging 10-30 days in 19.9 % of subjects, and > 30 days in 6.9 % of subjects. The majority of respondents is worried about their cough only after 1 week, but 76.9 % of subjects is much more worried if cough affects a child. After a few days of cough, 23.1 % of subjects use domestic remedies; 20.9 % ask their pharmacist, and 33.4 % their doctor, being GPs (69.6 %) and lung physicians (16.2 %) the most asked professionals. The occurrence of bronchitis, pneumonia, upper airway infections, and allergic troubles are the most feared events. The majority of respondents are convinced that antibiotics and steroids should not be regarded as the gold standard for treating persistent cough (61.2 and 58.2 %, respectively), while anti-tussive drugs and aerosols in general are regarded as the most effective strategies (69.1 and 74.1 %, respectively). Moreover, 33.8 % of the sample is in favour of homeopathic drugs, while 23.2 % had already used an homeopathic anti-tussive syrup, and 27.6 % of subjects are really interested in using the homeopathic approach. The willingness to pay for an effective anti tussive remedy was: 46.3 % up to 10 ?; 27.8 % up to 20 ?, and 13.3 % more than 20 ?. CONCLUSIONS: Cough confirms its high impact in Italy, and a substantial proportion of individuals regards cough as "a disease". Only one out of three Italians refers to their doctor, but when cough is already persistent. Cough in children is much more feared than in adults. The majority of Italians have a proper and conservative position versus both antibiotic and the systemic steroid uses against cough. The Italian attitude to aerosol therapy confirms very high. Differently from the cough guidelines, anti-tussive drugs are highly valued among Italian people. The attitude and the interest to homeopathic anti-tussive remedies proves high. Finally, the willingness to pay for an effective anti tussive remedy is quite high in Italy. PMID- 27708779 TI - Prospective study of percutaneous tracheostomy: Role of bronchoscopy and surgical technique. AB - OBJECTIVE: Percutaneous tracheostomy is a common procedure but varies considerably in approach. The aim of our study was to evaluate the need for intraoperative bronchoscopy and to compare various surgical techniques. METHODS: During 1 year all percutaneous tracheostomies in three intensive care units were prospectively documented according to a unified protocol. In one unit, bronchoscopy was used routinely and in others only during the study. RESULTS: A total of 111 subjects (77 males) with median age 64 (range, 18-86) years and body mass index 25.4 (range, 15.9-50.7) were included. In unit A, tracheal wall was directly exposed; in unit B, limited dissection to enable tracheal palpation was made. In both units, bronchoscopy was used to check the location of an already inserted guiding needle; needle position required correction in 8% and 12% of cases, respectively. In unit C, in tracheostomies without pretracheal tissue dissection, bronchoscopy was used to guide needle insertion; needle position required correction in 66% of cases. Median duration of operations performed by thoracic surgeons and residents was 10 (range, 3-37) min and by intensive care doctors and residents was 16.5 (range, 3-63) min (p < 0.001). Time from the beginning of preparations for tracheostomy until the end of the whole procedure was median 32 min for bedside tracheostomies and 64 min for operations in the operating theatre (p < 0.001). CONCLUSION: Limited pretracheal tissue dissection enabled proper guiding needle insertion and bronchoscopy was rarely needed. Percutaneous tracheostomies performed by thoracic surgeons took less time, and duration of the whole procedure was remarkably shorter when performed at bedside. PMID- 27708780 TI - Therapeutic drug monitoring of mexiletine at a large academic medical center. AB - INTRODUCTION: The therapeutic trough range for mexiletine (0.8-2 mcg/mL) was largely established in the setting of arrhythmia prophylaxis following myocardial infarction. OBJECTIVE: Describe the usage patterns of serum mexiletine concentrations and the impact of these concentrations on mexiletine dosing in modern practice for ventricular arrhythmia treatment. METHODS: A single-center, retrospective analysis was conducted using the electronic medical record to identify serum mexiletine concentrations drawn between December 2004 and December 2014. The primary endpoint was the incidence of mexiletine concentrations drawn as troughs. Secondary outcomes included the incidence of mexiletine concentrations that prompted a dose change, association between adverse events and elevated concentrations, and association between baseline characteristics and mexiletine concentrations. RESULTS: A total of 237 individual concentrations were included for analysis with 109 (46.0%) drawn appropriately as trough concentrations. Only 31 (13.1%) of the 237 concentrations drawn prompted a dose change. Mexiletine was primarily used for the treatment of ventricular arrhythmias (96.2%), and 108 (45.6%) concentrations were drawn in an effort to assess efficacy. The median concentration was statistically different between patients with and without an adverse event (0.8 vs 0.7 mcg/mL, respectively; p = 0.017), but may not represent a clinical significance. Patients with hepatic dysfunction had higher median concentrations compared to those without hepatic dysfunction (1.30 vs 1.07 mcg/mL; p = 0.01). CONCLUSION: Mexiletine concentrations are often drawn at inappropriate times and seldom influence a dose change. This study suggests that routine monitoring of mexiletine concentrations may not be necessary; however, therapeutic drug monitoring may be considered in patients with hepatic dysfunction or to confirm mexiletine absorption in patients where this represents a concern. PMID- 27708781 TI - Psychosis: call a surgeon? A rare etiology of psychosis requiring resection. AB - OBJECTIVE: Anti-N-methyl-d-aspartate receptor encephalitis is a rare but emerging cause of autoimmune encephalitis. Our objective is to present a case of this rare disease while highlighting the importance of an aggressive search for underlying malignancy as well as the common mischaracterization of primary psychiatric illness that occurs in these patients. METHODS: A young Caucasian female with no known psychiatric history presented with acute onset of seizures and psychosis. RESULTS: Magnetic resonance imaging abdomen and pelvis showed a 6-mm ovarian teratoma which was not visualized on initial computed tomographic scans. Pathology was consistent with a mature teratoma. Both serum and cerebrospinal fluid N-methyl-d-aspartate receptor antibodies were positive. CONCLUSION: An exhaustive search for underlying malignancy and specifically ovarian teratoma in young women should be completed in these patients. Diagnosis often is delayed given the prominent psychiatric manifestations and providers should be aware and strongly consider this in younger women with acute onset of neuropsychiatric symptoms. PMID- 27708782 TI - Delayed Type IIIb endoleak secondary to graft fabric tear 7 years following implantation of a Medtronic Talent endovascular aortic device: A case report and review of the literature. AB - OBJECTIVES: To report a rare case of delayed Type IIIb endoleak secondary to fabric tear following implantation of a Medtronic Talent endovascular device. METHODS: A 83-year old gentleman underwent elective endovascular aneurysm repair for infrarenal abdominal aortic aneurysm with a Medtronic bifurcated stent graft in 2008. RESULTS: Seven years after the initial repair, imaging surveillance revealed significant endoleak and brisk aneurysm sac expansion due to Type IIIb endoleak secondary to endograft limb fabric tear. CONCLUSIONS: This case illustrates the imperative role of imaging surveillance in detection of long-term endovascular aneurysm repair complications. Furthermore, we discuss exclusion of the graft tear with aortouniiliac stent grafting as the treatment for this complication.

AB - [This corrects the article DOI: 10.1186/s13102-016-0053-x.]. PMID- 27708784 TI - KIR repertory in patients with hematopoietic diseases and healthy family members. AB - BACKGROUND: Since the discovery of specific histocompatibility, literature has associated genes involved in the immune response, like the Human Leucocyte Antigen (HLA), with a better prognosis in transplantation. However, other non-HLA genes may also influence the immune process, such as the genes encoding the immunoglobulin-like receptors of natural killer cells (KIRs). The discovery that NK cell KIR receptors interact with conservative epitopes (C1, C2, Bw4) presented in HLA class I molecules that are genetically polymorphic, also observed in KIR genes, led to the investigation of the relevance of the KIR system to hematopoietic stem cell transplant. The cure of patients with leukemias and other hematological malignancies after bone marrow transplantation (BMT) has been attributed in part to the ability of the donor immune cells, present in the graft, to recognize and eliminate neoplastic cells of the patient. The cytotoxic activity of NK cells is mediated by the absence of HLA class I-specific ligands on the target cell surface to inhibitory KIR receptors (hypothesis of "missing self"). METHODS: We analyzed, by PCR typing-SSOP technique, the presence or absence of 16 KIR genes and haplotypes of 39 patients with hematopoietic disorders and 136 healthy individuals from Parana State. The comparisons made between the patient and control group were performed using chi2 test or Fisher exact test (bilateral p-value), as appropriated. Significance level was considered when p-value <= 0.05. RESULTS: Framework genes KIR3DL3, KIR3DP1, KIR2DL4 and KIR3DL2 were positive in all samples. The comparison between KIR repertoire of patients and healthy individuals revealed significant differences (p < 0.05) in inhibitors genes KIR2DL2 (p = 0.0005) and KIR2DL5 (p = 0.0067) and activating genes KIR2DS1 (p = 0.0013), KIR2DS2 (p = 0.0038), KIR2DS3 (p = 0.0153) that are more frequent in controls than in patients. The KIR2DS3 was significantly more frequent (p = 0.0031) in patients with acute myeloid leukemia (AML) when compared to patients with acute lymphoblastic leukemia (ALL). We observed a higher frequency of haplotype A (59 %) in the patients. CONCLUSION: Our data suggests that susceptibility to leukemia can be influenced, at least, partly byKIR receptors. PMID- 27708787 TI - Air pollution and urinary n-acetyl-B-glucosaminidase levels in residents living near a cement plant. AB - BACKGROUND: To identify adverse renal effects due to air pollution derived from a cement plant in Korea. Urinary n-acetyl-B-glucosaminidase (U-NAG) levels in residents living near a cement plant were compared to those in a group who lived farther away from the plant. METHODS: From June to August 2013 and from August to November 2014, laboratory tests for U-NAG and heavy metal were conducted on 547 study participants. Based on the level of air pollution exposure, subjects were divided into the "less exposed group," (LEG) which consisted of 66 persons who lived more than 5 km away from the cement plant, the "more exposed group from the rural area" (MEG-R), which consisted of 272 persons, and the "more exposed group from downtown area" (MEG-D), which consisted of 209 persons who lived within a 1 km radius of the cement plant. U-NAG levels >5.67 U/L were defined as "higher U NAG" levels. We compared the prevalence of higher U-NAG levels and estimated the adjusted odds ratio (OR) by air pollution exposure using a chi-square test and multiple logistic regression analysis. Further, we estimated the interaction between air pollution exposure and heavy metal exposure in renal toxicity. RESULTS: The OR of higher U-NAG levels by MEG-D and MEG-R compared to LEG was 2.13 (95 % CI 0.86-4.96) and 4.79 (95 CI 1.65-10.01), respectively. Urinary cadmium (U-Cd), urinary mercury (U-Hg), age, occupation, hypertension, and diabetes had a significant association with higher U-NAG levels. However, blood lead (B-Pb), sex, and smoking were not associated with higher U-NAG. Especially, concurrent exposure to heavy metals (U-Hg or/and U-Cd) and air pollution had an additive adverse effect. In the group with both 4th quartile heavy metal exposure (U-Cd or/and U-Hg) and air pollution exposure, the OR in MEG-R and MEG-D was 6.49 (95 % 1.42-29.65) and 8.12 (95 % CI 1.74-37.92), respectively, after adjustment for age, occupation, hypertension, diabetes. CONCLUSIONS: U-NAG levels seem to be affected by air pollution exposure as well as age, hypertension, diabetes, and even low levels of cadmium and low levels of mercury. Moreover, concurrent exposure to heavy metals and air pollution can have additive cytotoxic renal effects. PMID- 27708789 TI - Welcome to Nursing Open. PMID- 27708786 TI - Is there potential for the future provision of triage services in community pharmacy? AB - BACKGROUND: Worldwide the demands on emergency and primary health care services are increasing. General practitioners and accident and emergency departments are often used unnecessarily for the treatment of minor ailments. Community pharmacy is often the first port of call for patients in the provision of advice on minor ailments, advising the patient on treatment or referring the patient to an appropriate health professional when necessary. The potential for community pharmacists to act as providers of triage services has started to be recognised, and community pharmacy triage services (CPTS) are emerging in a number of countries. This review aimed to explore whether key components of triage services can be identified in the literature surrounding community pharmacy, to explore the evidence for the feasibility of implementing CPTS and to evaluate the evidence for the appropriateness of such services. METHODS: Systematic searches were conducted in MEDLINE, EMBASE and International Pharmaceutical Abstracts (IPA) databases from 1980 to March 2016. RESULTS: Key elements of community pharmacy triage were identified in 37 studies, which were included in the review. When a guideline or protocol was used, accuracy in identifying the presenting condition was high, with concordance rates ranging from 70 % to 97.6 % between the pharmacist and a medical expert. However, when guidelines and protocols were not used, often questioning was deemed insufficient. Where other health professionals had reviewed decisions made by pharmacists and their staff, e.g. around advice and referral, the decisions were considered to be appropriate in the majority of cases. Authors of the included studies provided recommendations for improving these services, including use of guidelines/protocols, education and staff training, documentation, improving communication between health professional groups and consideration of privacy and confidentiality. CONCLUSION: Whilst few studies had specifically trialled triage services, results from this review indicate that a CPTS is feasible and appropriate, and has the potential to reduce the burden on other healthcare services. Questions still remain on issues such as ensuring the consistency of the service, whether all pharmacies could provide this service and who will fund the service. PMID- 27708790 TI - An integrative review of the characteristics of meaningful learning in healthcare professionals to enlighten educational practices in health care. AB - AIM: Knowledge does not transfer automatically, but requires an active, personal progress through meaningful learning. As posited by the constructivist paradigm, the aim of this study was to identify the characteristics of meaningful learning by analysing definitions and correlated methods found in the literature. DESIGN: An integrative review. METHODS: Articles were sought on MEDLINE, CINAHL and SCOPUS; no language, time or study-design restrictions were adopted. Only papers referring explicitly to the diverse types of learning were taken into account; 11 articles were included in this review. RESULTS: Findings from the literature revealed three different types of meaningful learning: (1) meaningful learning as 'active building-up process'; (2) meaningful learning as 'change'; 3-meaningful learning as 'outcome of experience'. A focus on constructivism and meaningful learning provides a new outlook on healthcare professionals in learning, including nurses, who are gradually taking on greater responsibility in self- and ongoing education. PMID- 27708788 TI - A randomized, open-label pilot of the combination of low-level laser therapy and lorcaserin for weight loss. AB - BACKGROUND: Obesity is a significant public health problem and innovative treatments are needed. The purpose of this pilot study was to assess the preliminary efficacy and safety of a combined treatment of low-level laser therapy (LLLT) and lorcaserin on weight loss, health quality of life (QOL) measures, and cardiovascular risk factors. METHODS: Forty-five overweight and obese adult participants with a body mass index (BMI) >26.9 and <40 were randomized to receive LLLT, lorcaserin, or a combination of the two therapies. All study participants received treatment for 3 months and were followed for 3 months post-treatment. Participants were recruited from June 2014 through September 2014. RESULTS: The majority of the 44 participants accrued to this study were female (84 %) with an average age of 43.9 years (range 22 to 64 years). Most participants (93 % LLLT alone, 87 % LLLT + lorcaserin) completed at least 80 % of the LLLT treatments. From baseline to end of treatment, significant reductions in waist circumference were noted for each treatment group (-2.3 +/- 4.1 cm, -6.0 +/- 7.3 cm, and -4.0 +/- 5.5 cm for LLLT, lorcaserin and combination respectively); however, the reduction in body weight was only significant in those receiving lorcaserin and combination treatment (-0.4 +/- 1.5 kg, -1.3 +/- 1.2 kg and -1.3 +/- 1.3 kg). No significant differences were noted between the groups. Self-reported satisfaction was higher in the lorcaserin versus the LLLT group. CONCLUSION: This small pilot demonstrates that when combined with behavioral intervention, Lorcaserin and LLLT may be effective components of a comprehensive approach to the treatment of overweight and obesity in the clinical setting. Further studies with larger sample size and longer duration of treatment and follow-up are needed to further address efficacy. TRIAL REGISTRY INFORMATION: Trial registration: NCT02129608. Registered June 15, 2014. PMID- 27708791 TI - A secondary data analysis of Internet use in caregivers of persons with dementia. AB - AIM: This paper is a secondary data analysis to investigate relationships among caregiver stress appraisal, self-rated health and health-related Internet use. DESIGN: Cross-sectional correlation design. METHODS: National Alliance for Caregiving telephone survey conducted in the USA was a primary data source collected in 2009 from 258 caregivers of persons with dementia, who used the Internet to perform care-giving tasks. Based on Pearlin's Stress Process Model, structural equation modelling was conducted. RESULTS: Caregivers with poor health reported higher levels of caregiver stress appraised, which was associated with more Internet use for health-related purposes. It is required to develop effective Internet-based resources to meet the needs of highly stressed caregivers of persons with dementia. However, there was no relationship between self-rated health and health-related Internet use in dementia caregiver. PMID- 27708792 TI - Measurement of factors that negatively influence the outcome of quitting smoking among patients with COPD: psychometric analyses of the Try To Quit Smoking instrument. AB - AIMS: To test internal consistency and factor structure of a brief instrument called Trying to Quit smoking. BACKGROUND: The most effective treatment for patients with chronic obstructive pulmonary disease is to quit smoking. Constant thoughts about quitting and repeated quit attempts can generate destructive feelings and make it more difficult to quit. DESIGN: Development and psychometric testing of the Trying to Quit smoking scale. METHODS: The Trying to Quit smoking, an instrument designed to assess pressure-filled states of mind and corresponding pressure-relief strategies, was tested among 63 Swedish patients with chronic obstructive pulmonary disease. Among these, the psychometric properties of the instrument were analysed by Exploratory Factor Analyses. RESULTS: Fourteen items were included in the factor analyses, loading on three factors labelled: (1) development of pressure-filled mental states; (2) use of destructive pressure relief strategies; and (3) ambivalent thoughts when trying to quit smoking. These three factors accounted for more than 80% of the variance, performed well on the Kaiser-Meyer-Olkin (KMO) test and had high internal consistency. PMID- 27708793 TI - Understanding the perceptions and experiences of Certified Registered Nurse Anaesthetists regarding handovers: a focus group study. AB - AIM: The aim of this exploratory study was to gain further insight into the perceptions and experiences of Certified Registered Nurse Anaesthetists regarding intraoperative handovers of care. BACKGROUND: Handovers of care often result in adverse events in hospitalized patients and this risk is increased in the operating room setting where handovers occur frequently. Handovers between nurse anaesthetists, who provide the majority of anaesthesia in the United States today, is under-researched. DESIGN: Focus groups with Certified Registered Nurse Anaesthetists. METHODS: Two groups of nurse anaesthetists were recruited to participate in focus groups exploring their perception and experiences with intraoperative handovers of care. Content analysis was used to construe meaning from the context of the interviews. The findings were interpreted and discussed in a framework of Relationship-Based Care. FINDINGS: There were four main themes that emerged from the data: (1) characteristics of the setting are a threat to handover quality; (2) individual provider characteristics have an impact on handover quality; (3) The timing of the handover represents a threat to handover quality and (4) individual patient characteristics have an impact on handover quality. CONCLUSION: The specific threats to safe handover of care between nurse anaesthetists were perceived to fall into four major themes; this provides information needed to strengthen the environment of care and to improve safety in handover of care in the operating suite. PMID- 27708794 TI - A nurse-led intervention study: Promoting compliance with Diskus Inhaler use in asthma patients. AB - AIM: To examine the impact of a nurse-led patient assessment and education programme in promoting compliance with inhaler use in asthma patients. DESIGN: A quasi-experimental pre-test and post-test design. METHODS: A sample of asthmatic patients (N = 21) were recruited from the population of patients attending an asthma clinic. An Inhaler Proficiency Schedule (IPS) was developed and validated. At each visit, participants were requested to demonstrate their inhaler technique. The participants were investigated as to their confidence level with self-administration of their inhaler and adherence to prescribed doses. This information was recorded on a Patient-Reported Behaviour (PRB) questionnaire. RESULTS: Technique, compliance and patient confidence levels improved with nurse led education repeated over three visits; this was sustained on measurement at 6 months following completion of the education programme. PMID- 27708795 TI - What's different about Nursing Open? PMID- 27708797 TI - A prospective observational study of machine translation software to overcome the challenge of including ethnic diversity in healthcare research. AB - AIM: This study investigates whether machine translation could help with the challenge of enabling the inclusion of ethnic diversity in healthcare research. DESIGN: A two phase, prospective observational study. METHODS: Two machine translators, Google Translate and Babylon 9, were tested. Translation of the Strengths and Difficulties Questionnaire (SDQ) from 24 languages into English and translation of an English information sheet into Spanish and Chinese were quality scored. Quality was assessed using the Translation Assessment Quality Tool. RESULTS: Only six of the 48 translations of the SDQ were rated as acceptable, all from Google Translate. The mean number of acceptably translated sentences was higher (P = 0.001) for Google Translate 17.1 (sd 7.2) than for Babylon 9 11 (sd 7.9). Translation by Google Translate was better for Spanish and Chinese, although no score was in the acceptable range. Machine translation is not currently sufficiently accurate without editing to provide translation of materials for use in healthcare research. PMID- 27708796 TI - A qualitative exploration of nurses leaving nursing practice in China. AB - AIM: This paper reports a theoretical understanding of nurses leaving nursing practice by exploring the processes of decision-making by registered nurses in China on exiting clinical care. BACKGROUND: The loss of nurses through their voluntarily leaving nursing practice has not attracted much attention in China. There is a lack of an effective way to understand and communicate nursing workforce mobility in China and worldwide. DESIGN: This qualitative study draws on the constant comparative method following a grounded theory approach. METHOD: In-depth interviews with 19 nurses who had left nursing practice were theoretically sampled from one provincial capital city in China during August 2009-March 2010. RESULTS: The core category 'Mismatching Expectations: Individual vs. Organizational' emerged from leavers' accounts of their leaving. By illuminating the interrelationship between the core category and the main category 'Individual Perception of Power,' four nursing behaviour patterns were identified: (1) Voluntary leaving; (2) Passive staying; (3) Adaptive staying and (4) Active staying. PMID- 27708798 TI - A scoping review of family experience and need during end of life care in intensive care. AB - AIM: To scope systematically and collate qualitative studies on family experience and need during end of life care in intensive care, from the perspective of family members. DESIGN: Scoping review of qualitative research. METHODS: Standardized processes of study identification, data extraction and data synthesis were used. Multiple bibliographic databases were accessed during 2011 and updated in 2013. RESULTS: From an initial 876 references, 16 studies were identified for inclusion. These were predominantly single site, North American studies that explored issues relating to the temporal stages in the end of life trajectory and the requirement for information and emotional support at end of life. With a strong focus on family need and experience during the transition from active treatment to end of life care, more work is required to understand how doctors and nurses can support families from treatment withdrawal through to death. PMID- 27708800 TI - Ethics and open access. PMID- 27708799 TI - The significance of communities of practice: Norwegian nursing students' experience of clinical placement in Bangladesh. AB - AIM: The purpose of this study was to gain understanding of Norwegian students' experience of learning in clinical placement in Bangladesh without formal one-to one supervision, by a personal mentor in the ward. DESIGN: Using focus group interviews with bachelor nursing students we explored the significance of 'communities of practice' in nursing practicum abroad, socialization and knowledge transfer. METHOD: Seven third year bachelor nursing students enrolled in a clinical placement programme in Bangladesh participated in focus group interviews prior to their departure to Bangladesh, during their stay in Bangladesh and after their return to Norway. RESULTS: The Students' marginality and 'peripheral participation' triggered insight and reflection. The challenging but advantageous position of the peripheral students was heightened further due to the lack of one-to-one supervision in the clinic. Their previous experience with problem based learning and group learning was an asset that made them more resilient and helped them to cope. PMID- 27708801 TI - Generation Y New Zealand Registered Nurses' views about nursing work: a survey of motivation and maintenance factors. AB - AIM: The aim of this article was to report on the analysis of qualitative, open text data, received from a national on-line survey of what factors Generation Y New Zealand Registered Nurses wish to change about nursing and consideration of the potential policy and practice impacts of these requests on their retention. BACKGROUND: Prior to the economic recession of 2007-2010, the growing shortage of nurses in New Zealand presented a serious concern for the healthcare workforce. Given the ageing New Zealand nursing workforce, an ageing population and the increasing demands for health care, it is imperative that issues of retention of Generation Y nurses are resolved prior to the imminent retirement of more experienced nurses. DESIGN: A descriptive exploratory approach using a national wide, on-line survey, eliciting both quantitative and qualitative data was used. METHOD: The survey, conducted from August 2009-January 2010, collected data from Generation Y New Zealand Registered Nurses (n = 358) about their views about nursing, work and career. Herzberg's Motivation-Hygiene theory was used as the framework for the analysis of the open text data. RESULTS: The factors that nurses wanted changed were skewed towards Herzberg's hygiene-maintenance factors rather than motivating factors. This is of concern because hygiene-maintenance factors are considered to be dissatisfiers that are likely to push workers to another employment option. PMID- 27708802 TI - A survey of the breast care nurse role in the provision of information and supportive care to Australian women diagnosed with breast cancer. AB - AIM: To explore the role of the Australian breast care nurse in the provision of information and support to women with breast cancer, with a focus on the differences experienced depending on geographic work context. DESIGN: A cross sectional study. METHODS: This study conducted in 2013, involved surveying BCNs currently working in Australia, using a newly developed self-report online survey. RESULTS: Fifty breast care nurses completed the survey, 40% from major cities, 42% from inner regional Australia and 18% from outer regional, remote and very remote Australia. Patterns of service indicated higher caseloads in urban areas, with fewer kilometres served. Breast care nurses in outer regional, remote and very remote areas were less likely to work in multi-disciplinary teams and more likely to spend longer consulting with patients. Breast care nurses reported they undertook roles matching the competency standards related to the provision of education, information and support; however, there were barriers to fulfilling competencies including knowledge based limitations, time constraints and servicing large geographical areas. CONCLUSIONS: This was the first Australian study to describe the role of the breast care nurse nationally and the first study to investigate breast care nurses perceived ability to meet a selection of the Australian Specialist Breast Nurse Competency Standards. Important differences were found according to the geographical location of breast care nurses. PMID- 27708803 TI - Using principal components analysis to explore competence and confidence in student nurses as users of information and communication technologies. AB - AIM: To report on the relationship between competence and confidence in nursing students as users of information and communication technologies, using principal components analysis. DESIGN: In nurse education, learning about and learning using information and communication technologies is well established. Nursing students are one of the undergraduate populations in higher education required to use these resources for academic work and practice learning. Previous studies showing mixed experiences influenced the choice of an exploratory study to find out about information and communication technologies competence and confidence. A 48-item survey questionnaire was administered to a volunteer sample of first- and second-year nursing students between July 2008-April 2009. The cohort (N = 375) represented 18.75% of first- and second-year undergraduates. A comparison between this work and subsequent studies reveal some similar ongoing issues and ways to address them. METHODS: A principal components analysis (PCA) was carried out to determine the strength of the correlation between information and communication technologies competence and confidence. The aim was to show the presence of any underlying dimensions in the transformed data that would explain any variations in information and communication technologies competence and confidence. Cronbach's alpha values showed fair to good internal consistency. RESULTS: The five component structure gave medium to high results and explained 44.7% of the variance in the original data. Confidence had a high representation. The findings emphasized the shift towards social learning approaches for information and communication technologies. Informal social collaboration found favour with nursing students. Learning through talking, watching and listening all play a crucial role in the development of computing skills. PMID- 27708804 TI - The repositioning of hospitalized patients with reduced mobility: a prospective study. AB - AIM: To determine the frequency of patient repositioning across three consecutive nursing shifts (day, evening and night) and to identify predictors of repositioning frequency. BACKGROUND: Patient repositioning is a frequently implemented pressure injury prevention strategy. Yet, little is known about how often it should be implemented, or the frequency of movement among hospitalized patients with reduced mobility. DESIGN: An observational prospective study. METHODS: Chart audits were used to gather clinical and demographic data. Semi structured observations were conducted every 30 minutes for a continuous 24-hour period. Observational data included the patient's body position, the frequency of repositioning, assistance require to reposition and the use of support surfaces. RESULTS: Patients were repositioned frequently during the day and evening and least at night time. Elevation of the head of the bed (1-45 degrees ) was the most frequently adopted position. The independent predictors of repositioning frequency were age and gender, with older patients and males repositioned less frequently. PMID- 27708805 TI - Hijackers on the open access highway. PMID- 27708806 TI - "I know exactly what I'm going into": recommendations for pre-nursing experience from an evaluation of a pre-nursing scholarship in rural Scotland. AB - AIM: To develop a model of pre-nursing experience from evaluation of a pre nursing scholarship for school pupils in Scotland. DESIGN: Action research study. METHODS: School pupils (n = 42) completed questionnaire surveys and participated in anecdote circles. Student nurses acting as pupil 'buddies' (n = 33) participated in focus groups. Descriptive quantitative data and thematic analyses of qualitative data were integrated across cohorts and campuses. RESULTS: Ten recommended components of a model of pre-nursing experience were identified: educational experience of: (1) face-to-face on-campus teaching; (2) hands-on clinical skills sessions; and (3) andragogy, practice exposure to (4) nursing language; (5) nurses' emotional labour; (6) patients' stories; (7) pupils socializing with buddies; (8) buddies planning placement activities; and (9) supporting pupils during placements. Academic attainment was not a central component of the model due to pupils' need to (10) prioritize examined work for further/higher education entry. PMID- 27708807 TI - A qualitative study of professional caregivers' perceptions of processes contributing to mealtime agitation in persons with dementia in nursing home wards and strategies to attain calmness. AB - AIM: Describe professional caregivers' perceptions of factors and processes contributing to mealtime agitation and strategies for attaining and maintaining calm mealtimes. DESIGN: Qualitative and descriptive. METHODS: A convenience sample of professional caregivers working in two wards for residents with dementia was used. Data were collected during two focus-group interviews and supplemented with field notes from six reflection groups. Thematic content analysis was conducted. Data collection occurred from 2010-2011. RESULTS: Professional caregivers perceived agitation during mealtime as resulting from negative feelings in residents triggered by a lack of or negative social interaction, too much or ambiguous stimuli or demands exceeding residents' capacity. Strategies for attaining calm mealtimes involved thorough planning beforehand. During mealtime, professional caregivers focused on establishing a positive community around the table, helping residents focus on eating and continuously observing residents for subtle signals indicating that agitation was about to develop. The prerequisites to succeed with the strategies were knowledge of the residents' preferences and abilities, knowledge sharing within the team and awareness of one's own communication style. Thus, the professional caregivers operationalized person-centred care in a mealtime context. PMID- 27708808 TI - Managing perturbations during handover meetings: a joint activity framework. AB - AIM: To document the prevalence of perturbations of handover meetings and understand how nurses manage temporal, physical and social meeting boundaries in response to perturbations. BACKGROUND: Handovers are joint activities performed collaboratively by participating nurses. Perturbations of handover are frequent and may potentially threaten continuity of care. DESIGN: We observed and videotaped handovers during five successive days in four nursing care units in two Swiss hospitals in 2009. METHODS: Videorecordings were transcribed. All perturbations during the handovers were noted. We performed content analysis of the sources of perturbations from the notes and interactional micro-analyses of handover interactions based on video and transcripts. RESULTS: Nurses are the most frequent sources of perturbations during handovers. Perturbations are collaboratively managed. A tacit division of labour is enacted via multimodal communication strategies, whereby perturbations are dealt with using both linguistic and bodily signals. PMID- 27708809 TI - Pragmatism and integrated knowledge translation: exploring the compatabilities and tensions. AB - AIM: This paper presents a discussion of the role of the philosophy of pragmatism in the integrated knowledge translation approach to research. DESIGN: Critical inquiry is used to discuss bringing pragmatic philosophy and the integrated knowledge translation approach to research together to advance nursing knowledge. METHODS: This paper draws from the literature written on the philosophy of pragmatism and from the current literature on knowledge translation. The possibilities, tensions and limitations for underpinning an integrated knowledge translation research approach with pragmatic philosophy are discussed while highlighting the implications this has for creating knowledge aimed at advancing the practice of nursing. RESULTS: The implications for how nursing knowledge is created in using an integrated knowledge translation approach that is underpinned by pragmatic philosophy are important. Creating nursing knowledge that address the complex problems found in nursing practice is needed. In acknowledging the inseparability of knowledge and practice, researchers, practitioners, policy makers and the public can come together to co-create knowledge that is useful for the practice of nursing. It is these implications of underpinning an integrated knowledge translation research approach with pragmatic philosophy that are significant in creating nursing knowledge that advances the practice of nursing. PMID- 27708810 TI - Looking back on 2 years of Nursing Open: looking forward. PMID- 27708811 TI - Mary Seacole and claims of evidence-based practice and global influence. AB - AIM: The aim of this paper was to explore the contribution of Mary Seacole to nursing and health care, notably in comparison with that of Florence Nightingale. BACKGROUND: Much information is available, in print and electronic, that presents Mary Seacole as a nurse, even as a pioneer nurse and leader in public health care. Her own memoir and copious primary sources, show rather than she was a businesswoman, who gave assistance during the Crimean War, mainly to officers. Florence Nightingale's role as the major founder of the nursing profession, a visionary of public health care and key player in advocating 'environmental' health, reflected in her own Notes on Nursing, is ignored or misconstrued. DESIGN: Discussion paper. DATA SOURCES: British newspapers of 19th century and The Times digital archive; Australian and New Zealand newspaper archives, published memoirs, letters and biographies/autobiographies of Crimean War participants were the major sources. RESULTS: Careful examination of primary sources, notably digitized newspaper sources, British, Australian and New Zealand, show that the claims for Seacole's 'global influence' in nursing do not hold, while her use of 'practice-based evidence' might better be called self assessment. Primary sources, moreover, show substantial evidence of Nightingale's contributions to nursing and health care, in Australia, New Zealand, the USA and many countries and the UK much material shows her influence also on hospital safety and health promotion. PMID- 27708812 TI - A mixed-method study of pain management practice in a UK children's hospital: identification of barriers and developing strategies to maintain effective in patient paediatric pain management. AB - AIM: To assess Acute Pain Service and paediatric pain management efficacy in a UK specialist paediatric hospital to inform wider recommendations for future sustainability. BACKGROUND: UK paediatric acute pain services vary. Although comprehensive pain management guidelines exist, consensus on the best model of care is lacking. Worldwide, medical and pharmacological advances and rapid patient turnover have increased the challenges of managing hospitalized children's pain. Simultaneously nurses, who deliver the bulk of pain management, have experienced reduction in skill mix and training opportunities. Specialist Acute Pain Services have evolved to meet these demands; their overall efficacy is unknown. DESIGN: This mixed-methods study explores pain management practice at a UK paediatric hospital to assess current efficacy and future sustainability. METHOD: A 2013 case note review of all Acute Pain Services referrals over 14 days were compared with an interval sample of concurrent non-referred inpatient children; seven semi-structured interviews were conducted with a range of clinical staff. RESULTS: Twenty-two referrals of 15 children were made; 15 comparison children were identified. All 30 children (100%) were appropriately referred/non-referred. Acute Pain Services cases experienced higher pain levels, were more likely to have long term conditions, longer hospital stay and repeat admissions. Three key themes emerged through interview analysis: 'addressing pain', 'changing contexts' 'pain as an "expert" skill'. Increased specialization, reduced clarity between different pain modalities and decreased training opportunities had resulted in potentially unsustainable APS dependence. PMID- 27708813 TI - Developing an instrument to self-evaluate the Discharge Planning of Ward Nurses. AB - AIMS: To develop the Discharge Planning of Ward Nurses (DPWN), a Japanese self evaluation instrument for ward nurses' discharge planning practices. DESIGN: Cross-sectional survey. METHODS: Participants were 624 ward nurses from six hospitals in Japan with a discharge planning department. Items about discharge planning practices were collected from literature and interviews with nurses and researchers. Construct validity, concurrent validity, internal consistency and test-retest reliability were tested. RESULTS: Initially, 55 items were collected. Examination of the floor effect, item-total, good-poor analyses and exploratory factor analysis yielded a four-factor model with 24 items ('teaching home-care skills with community/hospital professionals,' 'identifying clients' potential needs early in the discharge process,' 'introducing social resources' and 'identifying client/family wishes and building consensus for discharge'). The four-factor structure was supported by confirmatory factor analysis. The DPWN correlated with scales ascertaining similar concepts, supporting concurrent validity. Internal consistency and test-retest reliability were generally satisfactory. PMID- 27708814 TI - Patient perceptions of nurse mentors facilitating the Aussie Heart Guide: A home based cardiac rehabilitation programme for rural patients. AB - AIM: To explore and describe long-term thoughts and perceptions of the Aussie Heart Guide Programme including the role of the mentor, held by patients recovering from myocardial infarction. DESIGN: A qualitative design. METHODS: Thirteen patients recovering from myocardial infarction who were unable to attend a hospital-based or affiliated outpatient cardiac rehabilitation programme were interviewed by telephone at the completion of the programme and asked to describe the relationship with their assigned nurse mentor and their perception of the audiovisual used in the programme. RESULTS: Three themes emerged; assisting me to cope, supporting me and my family and tailoring the programme to my needs. Patients were satisfied with the programme and appreciative of the supportive and caring relationships provided by mentors during their hospitalization through to their discharge from the programme. PMID- 27708816 TI - Beyond open access. PMID- 27708815 TI - Caregiver Contribution to Heart Failure Self-Care (CACHS). AB - AIM: While caregivers (CGs) make an important contribution to the self-care of heart failure (HF) patients, there are no reliable and valid tools for measuring such contributions. Current interventions that strive to optimize patient outcomes through self-care strategies neglect to account for CG contributions, a potential confounder on outcomes. The aim of the study was to develop an instrument that measures CG contributions to HF patients' self-care. DESIGN: The study design follows an established process for instrument development. METHODS: A systematic literature review and semi-structured interviews of CGs were conducted to identify measureable CG activities. Items were derived from thematic analysis of CG narratives. A content validity index was computed for each item (I CVI). Items with an I-CVI of >0.70 were retained. Items with an I-CVI of 0.50 0.70 were revised for clarification and items with an I-CVI <0.5 were discarded, except in instances where fulsome theoretical or empirical evidence supported their retention. RESULTS: 14 CGs completed interviews and 10 CGs with 4 expert nurses completed I-CVI testing. Major interview themes included arranging appointments, medication adherence, monitoring, coordinating care, encouraging independence and taking action. A total of 36 items were constructed and underwent I-CVI testing. Following I-CVI testing, 27 items were retained, seven items were retained after revision based on CG feedback and two items were removed. This newly developed 34-item questionnaire represents current literature, CGs' experiences, excellent I-CVI scores and ready for further psychometric testing. PMID- 27708818 TI - Factors associated with older people's independent living from the viewpoint of health and functional capacity: a register-based study. AB - AIM: The aim of this study was to identify factors associated with independent living of older people from the point of view of health and functional capacity. BACKGROUND: Living independently at home is major wish for older people but is depending on health and functional capacity among others. Objective and subjective assessments have been considered important in determining threats for independent living but both of these views have rarely included in the same study. DESIGN: Descriptive, cross-sectional register-based study was conducted. METHODS: Data were collected using the Health and Functional Capacity survey by identifying the factors of health examinations of a cohort (N = 292) of 75-year old's, born in 1936 (N = 388), in one Finnish medium-sized municipality in 2011. This study is part of the Functional Ageing project Kaste 2013. The data were analysed statistically by using descriptive analysis, cross-tabulation and logistic regression. RESULTS: Partly, different factors were associated with subjective and objective health and functional capacity showing wide range of individuality. Worsening subjective health was associated with worsened self assessment of life situation. Worsening subjective health threatens independent living. Factors statistically significantly associated with worsening subjective health were low physical activity, falls during the last 6 months, not managing heavy housework, being sometimes lonely or dejected, having diagnosed diseases or health problems and polypharmacy. PMID- 27708817 TI - An integrative review of the impact of mobile technologies used by healthcare professionals to support education and practice. AB - AIM: The aim of this study was to provide evidence of the impact of mobile technologies among healthcare professionals in education and practice settings. DESIGN: Integrative literature review. METHODS: Electronic databases including MEDLINE, CINAHL, PsycINFO, EMBASE, ERIC and Web of Science were searched for papers published between 2002-2012. Quantitative studies were critically evaluated based on Thomas et al.'s framework, while the consolidated criteria for reporting qualitative research was used to appraise the rigour of the qualitative studies. RESULTS: Seventeen quantitative and three qualitative studies were included. The findings suggest a largely positive influence of mobile technologies on various clinical practice and educational outcomes. However, robust evidence was limited. Use of mobile technologies in health care are associated with improvements in access to information, accuracy and efficiency, evidence-based decision making at the point of care and enhancement in performance, confidence and engagement in different contexts. PMID- 27708819 TI - Predictors of workplace violence among ambulance personnel: a longitudinal study. AB - AIM: To examine predictors of repeated confrontations with workplace violence among ambulance personnel, the proportion of exposure to potentially traumatic events that are aggression-related and to what extent personnel was able to prevent escalations. Although previous research assessed the prevalences among this group, little is known about predictors, to what extent PTE's are WPV related and their abilities to prevent escalations. DESIGN: A longitudinal study with a 6 months' time interval (N = 103). METHODS: At T1 demographics, workplace violence and potentially traumatic events in the past year, mental health, personality, handling of rules, coping and social organizational stressors were assessed. Confrontations with aggression were also examined at T2. RESULTS: Multivariate logistic regression analyses showed that only problems with superiors independently predicted repeated verbal aggression and that only the (absence of the) ability to compromise very easily predicted repeatedly being on guard and repeatedly confronted with any form of aggression. Due to very low prevalences, we could not examine predictors of repeated confrontations with physical aggression (N = 5) and serious threat (N = 7). A large majority reported that in most workplace violence cases they could prevent further escalations. About 2% reported a potentially traumatic event in the year before T1 that was WPV related and perceived as very stressful. PMID- 27708820 TI - Sources, incidence and effects of non-physical workplace violence against nurses in Ghana. AB - AIM: To document the incidence, sources and effects of workplace verbal abuse and sexual harassment against Ghanaian nurses. METHODS: A cross-sectional study was conducted in Ghana from 2013-2014 which surveyed 592 professional nurses and midwives working in public hospitals in Ghana using the health sector violence questionnaire. RESULTS: The majority of participants were females (80%). The average age of participants was 31.76 years and the average number of years practising as nurse was 7.38. Twelve per cent of the participants experienced at least one incident of sexual harassment and 52.2% were exposed to verbal abuse. The majority of perpetrators of sexual harassment were medical doctors (50%). Relatives of patients emerged as the most frequent verbal abusers (45.5%). Chi square test showed statistically significant associations between gender and workplace violence and between workplace violence and intention to quit the nursing profession. The effects of workplace violence ranged from having disturbing memories about the incident to being 'super alert' and vigilant. Establishing the incidence of workplace violence is a necessary step towards addressing the problem. It is concluded that educational programs must be designed for healthcare workers and the general public to foster awareness of the effects of workplace violence. Clear policies must also be instituted to address the problem. PMID- 27708822 TI - What are Altmetrics and why would anyone be interested? PMID- 27708821 TI - Using cognitive behaviour therapy to explore resilience in the life-stories of 16 UK centenarians. AB - AIM: In 2010, we interviewed 16 UK centenarians about their lives and later published a paper on the socio-emotional aspects of positive ageing. We were struck by their ability to 'move on' from difficult situations which we recognized conceptually as 'resilience'. In the effort to understand aspects of resilience as portrayed in their stories, we re-examined their data. METHODOLOGY: In the original study, we used participatory action research (PAR) for its storytelling and group process components. Here, we re-examine data from the centenarians' life stories using a cognitive behavioural therapy (CBT) lens. DESIGN: We focused on the notion of resilience in the centenarians' stories guided by CBT insights to analyse and develop psychosocial interpretations. RESULTS: Resilience comprised the ability to frame difficult life events in positive terms, accept what cannot be changed, manage worry and anxiety effectively, develop psychological flexibility in the face of change and continually seek opportunities for growth and development. We suggest that these resilient behaviours may have contributed to positive ageing. PMID- 27708823 TI - What are health professionals' intentions toward using research and products of research in clinical practice? A systematic review and narrative synthesis. AB - AIM: To explore health professionals' intentional behaviour and what determines their intention to use products of research in clinical practice. BACKGROUND: Trying to get research and products of research into clinical practice is an enduring problem. A clearer picture is emerging as to how individual practitioners respond toward practical problems of changing clinical practice, but this does not include health professionals' intentions to use products of research and what influences their intentions. DESIGN: Systematic Review and Narrative Synthesis. DATA SOURCES: Five databases were searched systematically. This included BNI, HMIC, Psych INFO, CINHAL and MEDLINE; articles published in the English language only were included. REVIEW METHODS: PRISMA guidelines were used as a framework for structuring the review and methods of narrative synthesis to analyse study outcomes. RESULTS: Eighteen studies matched the final inclusion criteria. All studies used questionnaires to measure intention. Most studies involved Nurses or Physicians. Nurses' intentions were mostly influenced by their perceived ability to use guidelines in their practice. Physicians' intentions were often influenced by their perceptions of the usefulness and relevance of the guideline and peer pressure amongst the professional group. Practice habits, when added to intentional models were also predictive of intentional behaviour. In studies that compared intentions with behaviour, the level of intention often did not match self-report or actual behaviour. PMID- 27708824 TI - Effects of training on attitudes of psychiatric personnel towards patients who self-injure. AB - BACKGROUND: Improving attitudes of personnel towards self-injurious patients leads to better working alliance and contributes to better patient outcomes. Previous research into the improvement of these attitudes has recorded the need for specific training in evidence-based assessment and treatment of self injurious patients. AIM: The current study describes the attitudes towards self injurious patients among psychiatric personnel. The study also evaluates the effect of a structured clinical training program on psychiatric personnel's attitudes towards patients who self-injure. It further examines whether age, education, frequency of self-injurious patients contact, and work experience of the personnel are associated with the existing attitudes. METHODS: Psychiatric personnel (N = 50) attended a four-day training program, presenting evidence based knowledge regarding self-injury assessment and treatment, using group exercises and reflective learning principles. The personnel completed the Understanding Suicidal Patients Questionnaire (USP) anonymously PreTraining, on 17 January 2014, and PostTraining, on 20 June 2014. The mean differences as well as single USP items before and after the training were tested by unpaired t-test. Two-way ANOVA was used to test impact of background variables on the USP scores. RESULTS: The training program had statistically significant impact (P < 0.01) on the following individual items of the USP scale: Patients who have tried to commit suicide are usually treated well in my work unit (d = 1.02); A person who has made several suicide attempt is at greater risk of committing suicide (d = 0.64); Because the patients who have tried to commit suicide have emotional problems, they need the best possible treatment (d = 0.57). The results also suggested that the frequency of patient contact had impact on attitudes towards self-injurious patients. PMID- 27708825 TI - Characteristics of patients who are admitted with or acquire Pressure Ulcers in a District General Hospital; a 3 year retrospective analysis. AB - AIM: The study aimed to characterize demographic and clinical practice factors associated with community (CAPU) and hospital acquired pressure ulcers (HAPU). DESIGN: A comparative retrospective evaluation of pressure ulcer data, collected from a district general hospital. METHODS: Demographic and pressure ulcer related data were collected from patients at risk of developing a pressure ulcer, collated by a single observer using a standardized tool. Comparisons were made within and between patient groups (no PU, CAPU and HAPU). RESULTS: CAPU and HAPU patient groups were significantly (P < 0.001) older, had extended lengths of hospital stay and were less likely to be provided quickly with a pressure relieving support surface than those with no PU. HAPU patients had a longer length of stay and a higher proportion of heel PUs compared to CAPU. PMID- 27708826 TI - Nursing documentation of pressure ulcers in nursing homes: comparison of record content and patient examinations. AB - AIM: The aim of this study was to describe the accuracy and quality of nursing documentation of the prevalence, risk factors and prevention of pressure ulcers, and compare retrospective audits of nursing documentation with patient examinations conducted in nursing homes. DESIGN: This study used a cross sectional descriptive design. METHOD: A retrospective audit of 155 patients' records and patient examinations using the European Pressure Ulcer Advisory Panel form and the Braden scale, conducted in January and February 2013. RESULTS: The prevalence of pressure ulcers was 38 (26%) in the audit of the patient records and 33 (22%) in patient examinations. A total of 17 (45%) of the documented pressure ulcers were not graded. When comparing the patient examinations with the patient record contents, the patient records lacked information about pressure ulcers and preventive interventions. PMID- 27708827 TI - Surgical readmissions: results of integrating pre-, peri- and postsurgical care. AB - AIMS: To explore the feasibility of recruiting surgical oncology patients and implementing a surgical integrated discharge (SID) programme led by advanced practice providers (APP). BACKGROUND: Burden of illness and complexity of treatment regimen makes it challenging for surgical oncology patients to participate in research. Surgical oncology nurses may have the necessary expertise to overcome this problem. DESIGN: Controlled longitudinal prospective observational study. METHODS: The SID programme included multidisciplinary care coordination, regular communication among APPs and proactive postdischarge follow up. Administrative databases were used to identify matching historical controls (n = 113) and evaluate programme outcomes. RESULTS: Patient enrolment was 84%. The main challenges for the programme implementation included incompatible health information systems among care settings, variation in care processes among hospital units and need for provider behaviour change. CONCLUSIONS: Most surgical oncology patients are willing to participate in outcomes programmes when contacted by familiar clinical personnel but programme implementation requires leadership support, communication among care teams and training and infrastructure. PMID- 27708829 TI - Editorial. PMID- 27708828 TI - Shared decision-making on a 'life-and-care plan' in long-term care facilities: research protocol. AB - AIM: To determine whether the number of residents' preferences and needs together with the actions taken to satisfy them recorded into their 'life-and-care plans' will increase and the process of shared decision-making will improve the residents' psychosocial well-being. BACKGROUND: Shared decision-making is defined as a process where healthcare professionals and patients make decisions together, using the best available evidence. The aims of the present study were to assess the feasibility and acceptability of an SDM framework for care planning in long term care facilities and its potential effectiveness on the proportion of dementia residents whose own preferences and needs and the related actions, are known, satisfied and documented in their 'life-and-care plans'. DESIGN: The current project is a feasibility trial and it was approved in November 2013. METHODS: Research subjects are triads composed of the resident with dementia, a family caregiver and the professional usually taking care for the resident. Professional caregivers of two nursing homes, one located in Italy and one in the Netherlands, will receive a specific training in SDM principles and will guide the SDM interview in the triad. The primary outcome will be the proportion of residents whose preferences and needs, together with the related actions to meet them, are known, documented and satisfied in their 'life-and-care plans'. TRIAL REGISTRATION: NCT02118701. PMID- 27708830 TI - Peer review and the publication process. AB - AIMS: To provide an overview of the peer review process, its various types, selection of peer reviewers, the purpose and significance of the peer review with regard to the assessment and management of quality of publications in academic journals. DESIGN: Discussion paper. METHODS: This paper draws on information gained from literature on the peer review process and the authors' knowledge and experience of contributing as peer reviewers and editors in the field of health care, including nursing. RESULTS: There are various types of peer review: single blind; double blind; open; and post-publication review. The role of the reviewers in reviewing manuscripts and their contribution to the scientific and academic community remains important. PMID- 27708831 TI - Patient complaints about health care in a Swedish County: characteristics and satisfaction after handling. AB - AIM: To describe patient complaints and to examine possible associations between healthcare providers' statements and reports of satisfaction/dissatisfaction. DESIGN: A retrospective and descriptive design was used to examine filed complaints. METHODS: Complaints from one Patient Advisory Committee in Sweden in 2011 was examined using three different protocols/reading guides (n = 618). Associations between contents in responses from healthcare providers and reports of satisfaction/dissatisfaction from the complainants were analysed. RESULTS: Less than one-third of the complainants were satisfied after handling and with healthcare providers' statements about the complaint. The most frequent causes for dissatisfaction were that the healthcare provider 'did not tell the truth' or 'gave insufficient information'. There was a statistically significant association with dissatisfaction if the statement from the healthcare provider included the category 'disagree/defend themselves'. Four categories were associated with being satisfied and the associations were statistically significant when two or more of these were combined. PMID- 27708833 TI - Re-establishing and preserving hope of recovery through user participation in patients with a severe mental disorder: the self-referral-to-inpatient-treatment project. AB - AIMS: The treatment of patients with a severe mental disorder is generally not good enough. The aim of this article was to illustrate some alternative approaches for better understanding and treatment for the individual, besides seeing and interpreting the symptoms. METHODS: The context of understanding is regulation of emotions whit a person-based approach. The self-referral-to inpatient-treatment project is presented and discussed as a possible method of intervention to improve patient involvement. DESIGN: Theoretical approach. RESULTS: Involvement in genuine decisions, where the individual is in control and feels emotionally robust, is important. The experience of regaining authority through being self-empowered with sufficient environmental support is essential for re-establishing and preserving hope of recovery. PMID- 27708832 TI - Dispositional mindfulness and employment status as predictors of resilience in third year nursing students: a quantitative study. AB - BACKGROUND: Nursing students will graduate into stressful workplace environments and resilience is an essential acquired ability for surviving the workplace. Few studies have explored the relationship between resilience and the degree of innate dispositional mindfulness, compassion, compassion fatigue and burnout in nursing students, including those who find themselves in the position of needing to work in addition to their academic responsibilities. AIM: This paper investigates the predictors of resilience, including dispositional mindfulness and employment status of third year nursing students from three Australian universities. DESIGN: Participants were 240 undergraduate, third year, nursing students. Participants completed a resilience measure (Connor-Davidson Resilience Scale, CD-RISC), measures of dispositional mindfulness (Cognitive and Affective Mindfulness Scale Revised, CAMS-R) and professional quality of life (The Professional Quality of Life Scale version 5, PROQOL5), such as compassion satisfaction, compassion fatigue and burnout. METHOD: An observational quantitative successive independent samples survey design was employed. A stepwise linear regression was used to evaluate the extent to which predictive variables were related each to resilience. RESULTS: The predictive model explained 57% of the variance in resilience. Dispositional mindfulness subset acceptance made the strongest contribution, followed by the expectation of a graduate nurse transition programme acceptance, with dispositional mindfulness total score and employment greater than 20 hours per week making the smallest contribution. This was a resilient group of nursing students who rated high with dispositional mindfulness and exhibited hopeful and positive aspirations for obtaining a position in a competitive graduate nurse transition programme after graduation. PMID- 27708834 TI - Outcomes from a pilot psychological therapies service for UK military veterans. AB - AIM: To evaluate the outcomes of participants attending a psychological therapies service for military veterans. BACKGROUND: The UK Military Veterans' Improving Access to Psychological Therapies Service (North West) (MV IAPT) provided a clinical psychological therapies service for military veterans. Outcomes of depression, anxiety and social adjustment were assessed after treatment in the service's pilot phase. DESIGN: An observational, prospective cohort study examined changes in depression, anxiety and social adjustment during receipt of the service. METHODS: Changes in depression (PHQ-9), anxiety (GAD-7) and social adjustment (WSAS) were examined in 952 veterans referred over 20 months from September 2011. Data were collected using the IAPT clinical information system plus additional fields. Changes for patients who completed treatment, remained in treatment and dropped out were compared. RESULTS: Seven hundred and seven veterans received an initial assessment, from which 505 received two or more appointments. Of these, 156 completed treatments, 179 remained in treatment and 170 dropped out. The majority of veterans had been operationally deployed and were similar in risk characteristics to those in other military cohort studies. There were highly significant improvements on all measures (p<.01), with completers improving more and having higher rates of recovery from depression and anxiety than those remaining and drop outs. Recovery rates compared favourably with evaluations of general IAPT services and also exceeded reported natural recovery rates. PMID- 27708835 TI - Validation of the Spanish version of the Edinburgh feeding evaluation in dementia scale applied to institutionalized older persons with dementia: a study protocol. AB - AIM: The aim of this study was to obtain a Spanish version of the Edinburgh Feeding Evaluation in Dementia Scale version, to assess its reliability for use by medical staff and caregivers at residential care homes, to evaluate by confirmatory methods its construct validity. A further aim was to determine the criterion validity with respect to biochemical markers of malnutrition such as serum albumin, transferrin, cholesterol and lymphocytes, the body mass index and the mini nutritional assessment. DESIGN: Clinimetric cross-validation study. METHODS: Institutionalized subjects with dementia will be observed while consuming meals and evaluated with the instrument independently by nurses and caregivers. PMID- 27708838 TI - Editorial. PMID- 27708837 TI - A novel predictive factor for the onset time of docetaxel-induced onychopathy: a multicenter retrospective study. AB - BACKGROUND: Taxanes are known to cause onychopathy. Previous studies have reported the relationship between onychopathy and paclitaxel dosing intervals and cumulative doses. However, there are no studies of the predictive factors for docetaxel-induced nail changes. The present study used the drug accumulation rate (mg/m2/day) as a novel indicator and evaluated its usefulness for the prediction of onychopathy. METHODS: From January 2008 to December 2009, we examined patients who received docetaxel at the Toyama University Hospital and Tonami General Hospital to determine the time to onset of onychopathy, the accumulation rate, and the cumulative dose. We then divided the study subjects into two groups, and used Receiver Operating Characteristic (ROC) analysis to calculate a cut-off value. We evaluated both indicators as predictive factors for onychopathy using the log-rank test and Cox proportional hazards model. RESULTS: Ninety-five patients were included in the present study. The results of the log-rank test sub analysis revealed that the median number of days until onychopathy onset was significantly shorter in patients with an accumulation rate greater than the cut off (P = 0.009), and in those with a cumulative dose below the cut-off (P < 0.001). The hazard ratios for the accumulation rate and cumulative dose, evaluated using Cox proportional hazards regression analysis, were 1.44 (P = 0.036) and 0.99 (P < 0.001), respectively. CONCLUSIONS: The results of the present study indicated that the drug accumulation rate influenced the time to onset of docetaxel-induced onychopathy. TRIAL REGISTRATION: This study is not applicable for trial registration due to retrospective chart review without intervention. PMID- 27708839 TI - Mediating effects of dietary intake on associations of TV viewing, body mass index and metabolic syndrome in adolescents. AB - OBJECTIVE: Evidence suggests that TV viewing is associated with body mass index (BMI) and metabolic syndrome (MetS) in adolescents. However, it is unclear whether dietary intake mediates these relationships. METHODS: A cross-sectional analysis was conducted in adolescents (12-19 years) participating in the 2003 2006 United States National Health and Nutrition Examination Survey. BMI z scores (zBMI) (n = 3,161) and MetS (n = 1,379) were calculated using age- and sex specific criteria for adolescents. TV viewing (h/day) was measured via a self reported questionnaire, and dietary intake was assessed using two 24-h recalls. Using the MacKinnon method, a series of mediation analyses were conducted examining five dietary mediators (total energy intake, fruit and vegetable intake, discretionary snacks, sugar-sweetened beverages and diet quality) of the relationships between TV viewing and zBMI and MetS. RESULTS: Small positive relationships were observed between TV viewing and zBMI (beta = 0.99, p < 0.001) and TV viewing and MetS (OR = 1.18, p = 0.046). No dietary element appeared to mediate the relationship between TV viewing and zBMI. However, sugar-sweetened beverage consumption and fruit and vegetable intake partially mediated the relationship between TV viewing and MetS, explaining 8.7% and 4.1% of the relationship, respectively. CONCLUSIONS: These findings highlight the complexity of the relationships between TV viewing, dietary intake and cardiometabolic health outcomes, and that TV viewing should remain a target for interventions. PMID- 27708840 TI - Portion-size preference as a function of individuals' body mass index. AB - OBJECTIVE: Large portions of food are often blamed for rising rates of obesity. We tested the possibility that people who are heavier may tend to select or prefer larger portions than do people who are lighter. METHODS: Participants (total N = 798) were asked to choose between a small and larger portion of pasta for a hypothetical meal (Studies 1, 2 and 4), to indicate their ideal portion from a range of portion-size options (Study 2), or to select their preferred portion size from each of 28 portion pairs (Study 3). RESULTS: Across all studies, there were no significant differences between heavier and lighter participants in their portion-size selection (effect sizes ranged from d = -0.06 to 0.33). The pattern was the same regardless of whether we grouped participants as having a body mass index (BMI) <25 vs. >=25, as having a BMI of <30 vs. >=30, or treated BMI as a continuous predictor. CONCLUSIONS: Given the lack of association between BMI and portion-size preference, we suggest that factors other than portion size, such as differences in meal frequency, food type, plate clearing or compensation at subsequent meals, may need to be considered in order to explain the increasing prevalence of obesity. PMID- 27708836 TI - Pathophysiology of sepsis-induced myocardial dysfunction. AB - Sepsis-induced myocardial dysfunction is a common complication in septic patients and is associated with increased mortality. In the clinical setting, it was once believed that myocardial dysfunction was not a major pathological process in the septic patients, at least in part, due to the unavailability of suitable clinical markers to assess intrinsic myocardial function during sepsis. Although sepsis induced myocardial dysfunction has been studied in clinical and basic research for more than 30 years, its pathophysiology is not completely understood, and no specific therapies for this disorder exist. The purpose of this review is to summarize our current knowledge of sepsis-induced myocardial dysfunction with a special focus on pathogenesis and clinical characteristics. PMID- 27708841 TI - Response to a standard behavioral weight loss intervention by age of onset of obesity. AB - BACKGROUND: The purpose of this study was to examine weight loss, physical activity, fitness and diet changes in response to a standard behavioral weight loss intervention in adults with self-reported juvenile onset (n = 61) or adult onset (n = 116) obesity. METHODS: Participants (n = 177; 43.0 +/- 8.6 years; body mass index [BMI] = 33.0 +/- 3.4 kg m-2) engaged in an 18-month standard behavioral weight loss intervention. Participants were randomized into three different intervention groups as part of the larger parent trial. BMI, physical activity, fitness and diet were assessed at baseline, 6, 12 and 18 months. Separate adjusted mixed models were constructed using SAS version 9.4 (SAS Institute, Cary, NC). RESULTS: There was significant weight loss, increased physical activity, improved fitness and reduced caloric intake over time (p < 0.001). There were no significant differences in these outcome variables by obesity onset group. However, there was a significant group by time interaction for fitness (p = 0.001), with the adult onset making significantly greater gains in fitness from baseline to 6 months (p < 0.001); however, this difference was no longer present at 12 or 18 months. CONCLUSIONS: With the exception of fitness at 6 months, weight loss, physical activity and diet did not differ between juvenile onset and adult onset participants, suggesting that those with juvenile onset obesity are equally responsive to a standard behavioral weight loss intervention in adulthood. PMID- 27708842 TI - Maximizing retention in long-term clinical trials of a weight loss agent: use of a dietitian support team. AB - OBJECTIVE: High-attrition rates have been observed in long-term clinical trials of weight loss agents. We evaluated the impact of an innovative retention programme on 1-year retention. METHODS: Three Phase 3 global multicentre clinical trials evaluated the efficacy and safety of a CB1 receptor antagonist in subjects with BMI >= or = 27 kg/m2. The impact of a multifaceted retention programme including a dietitian screening interview, a comprehensive culturally adapted lifestyle modification programme, and a dietitian support system to maximize lifestyle adherence, was evaluated in 4,410 subjects from four subpopulations (non-US English-speaking, non-English-speaking, US-without dietitian screening and US-with dietitian screening) comprising 208 centres from 15 countries. RESULTS: The median proportion retained over the first year among subjects in three protocols was 82%. Non-English-speaking countries showed higher retention rates (89%) compared with the USA (73%) and non-US English-speaking (81%) countries. Within the USA, behavioural screening was associated with 29% reduction in dropout rate; for every five monthly teleconferences attended above 11, there was a 32% decrease in dropout rate. CONCLUSIONS: This novel retention programme greatly improved upon reported retention rates of studies conducted with other weight loss agents in long-term clinical trials. Its effectiveness should be confirmed in future trials. PMID- 27708843 TI - Current practices of obesity pharmacotherapy, bariatric surgery referral and coding for counselling by healthcare professionals. AB - INTRODUCTION: Rates of obesity pharmacotherapy use, bariatric surgery and intensive behavioural counselling have been extremely low. OBJECTIVES: The primary objective of this study was to survey healthcare provider beliefs, practice and knowledge regarding obesity management. METHODS: Primary care physicians (PCPs), OB-GYN physicians and nurse practitioners (NPs) responded to a web-based survey related to drug therapy practice, bariatric surgery referral and reimbursement coding practice. RESULTS: Rates of reported use of obesity pharmacotherapy appear to be increasing among PCPs, which is likely related to the approval of four new obesity pharmacotherapy agents since 2012. Rates of pharmacotherapy use among OB-GYNs and NPs appear much lower. Similarly, few PCPs are averse to recommending bariatric surgery, but aversion among OB-GYNs and NPs is significantly higher. CONCLUSION: Together, these observations suggest that OB GYN and NP populations are important targets for education about obesity management. Very few PCPs, OB-GYNs or NPs use behavioural counselling coding for obesity. Better understanding of why this benefit is not being fully used could inform outreach to improve counselling rates. PMID- 27708845 TI - Lifestyle modification interventions differing in intensity and dietary stringency improve insulin resistance through changes in lipoprotein profiles. AB - OBJECTIVE: Metabolic dysfunction characterized by insulin resistance (IR) is an important risk factor for type-2 diabetes and coronary artery disease (CAD). The aim of this study was to determine if clinical lifestyle interventions differing in scope and intensity improve IR, defined by the lipoprotein IR (LPIR) score, in individuals differing in the severity of metabolic dysfunction. METHODS: Subjects with diagnosed type-2 diabetes, CAD or significant risk factors participated in one of two clinical lifestyle modification interventions: (i) intensive non randomized programme with a strict vegetarian diet (n = 90 participants, 90 matched controls) or (ii) moderate randomized trial following a Mediterranean style diet (n = 89 subjects, 58 controls). On-treatment and intention-to-treat analyses assessed changes over 1 year in LPIR, lipoprotein profiles and metabolic risk factors in intervention participants and controls in both programmes. RESULTS: In the on-treatment analysis, both interventions led to weight loss: [ 8.9% (95% CI, -10.3 to -7.4), intensive programme; -2.8% (95% CI, -3.8 to -1.9), moderate programme; adjusted P < 0.001] and a decrease in the LPIR score [-13.3% (95% CI, -18.2 to -8.3), intensive; -8.8% (95% CI, -12.9 to -4.7), moderate; adjusted P < 0.01] compared with respective controls. Of the six lipoprotein parameters comprising LPIR, only large very-low-density lipoprotein particle concentrations decreased significantly in participants compared with controls in both programmes [-26.3% (95% CI, -43.0 to -9.6), intensive; -14.2% (95% CI, -27.4 to -1.0), moderate; P < 0.05]. Intention-to-treat analysis confirmed and strengthened the primary results. CONCLUSION: A stringent lifestyle modification intervention with a vegetarian diet and a moderate lifestyle modification intervention following a Mediterranean diet were both effective for improving IR defined by the LPIR score. PMID- 27708844 TI - Anthropometric predictors of body fat in a large population of 9-year-old school aged children. AB - OBJECTIVE: To develop and cross-validate predictive models for percentage body fat (%BF) from anthropometric measurements [including BMI z-score (zBMI) and calf circumference (CC)] excluding skinfold thickness. METHODS: A descriptive study was carried out in 3,084 pre-pubertal children. Regression models and neural network were developed with %BF measured by Bioelectrical Impedance Analysis (BIA) as the dependent variables and age, sex and anthropometric measurements as independent predictors. RESULTS: All %BF grade predictive models presented a good global accuracy (>=91.3%) for obesity discrimination. Both overfat/obese and obese prediction models presented respectively good sensitivity (78.6% and 71.0%), specificity (98.0% and 99.2%) and reliability for positive or negative test results (>=82% and >=96%). For boys, the order of parameters, by relative weight in the predictive model, was zBMI, height, waist-circumference-to-height ratio (WHtR) squared variable (_Q), age, weight, CC_Q and hip circumference (HC)_Q (adjusted r2 = 0.847 and RMSE = 2.852); for girls it was zBMI, WHtR_Q, height, age, HC_Q and CC_Q (adjusted r2 = 0.872 and RMSE = 2.171). CONCLUSION: %BF can be graded and predicted with relative accuracy from anthropometric measurements excluding skinfold thickness. Fitness and cross-validation results showed that our multivariable regression model performed better in this population than did some previously published models. PMID- 27708847 TI - Lifestyle modification intervention improves glycemic control in Mongolian adults who are overweight or obese with newly diagnosed type 2 diabetes. AB - OBJECTIVE: To evaluate the effectiveness of a weight loss intervention in Mongolian adults with newly diagnosed type 2 diabetes mellitus and with BMIs >= 25.0 kg/m2. METHODS: Eighty participants (33 men/47 women) aged 32-56 years old received education sessions to improve nutritional habits and increase physical activity. Participants were counselled in-person on two occasions with regular follow-up by phone to eat less (reduce calorie intake by 30-40% and consume fewer fatty foods), shift food intake to earlier in a day and increase physical activity such as walking, jogging, running and biking. Measurements were performed before and after the 6-month intervention. RESULTS: After 6 months, the average weight loss was 4.3 +/- 4.7 kg, representing a 4.9 +/- 5.4% reduction in body weight (p < 0.0001). Mean HbA1c decreased from 8.5 +/- 2.7% to 6.0 +/- 1.8% (p < 0.0001), and the percent of individuals with HbA1c in the diabetic range dropped from 76.3% to 27.5%. These changes were accompanied by marked improvements in cardiovascular risk factors, including total cholesterol (3.92 +/ 1.02 to 3.13 +/- 0.80 mmol/l; p < 0.0001) and triglycerides (2.11 +/- 0.82 to 1.54 +/- 0.51 mmol/l; p < 0.0001), and modest reductions in systolic and diastolic blood pressure (p < 0.05). CONCLUSION: The remarkable improvement in glycemic control and lipid profile in participants suggests that a lifestyle modification intervention targeting weight loss may be highly effective for early diabetes treatment and prevention in Mongolians. PMID- 27708846 TI - Alternate-day versus daily energy restriction diets: which is more effective for weight loss? A systematic review and meta-analysis. AB - BACKGROUND: Alternate-day-fasting (ADF) has been proposed as an effective dieting method. Studies have found that it also can increase life span in rodents, and reduce inflammation in humans. The aim of this paper was to systematically review the efficacy of ADF compared to very-low-calorie dieting (VLCD) in terms of weight loss, and reduction of fat mass and fat-free mass. METHODS: Systematic review: PubMed literature searches were performed. Fixed review procedures were applied. Studies were evaluated for quality. Twenty-eight studies were included. Meta-analysis: 10/28 studies (four ADF and six matched VLCD) were further analyzed. RESULTS: After adjustment for BMI and duration, there was no significant difference in mean body weight loss (VLCD 0.88 kg more weight loss than ADF, 95% CI: -4.32, 2.56) or fat-free mass (VLCD 1.69 kg more fat-free mass loss than ADF, 95% CI: -3.62, 0.23); there was a significant difference observed in fat mass (ADF 3.31 kg more fat mass loss than VLCD, 95% CI: 0.05, 6.56). Meta analysis showed that, among ADF studies, the pooled change in body weight, fat mass and fat-free mass was 4.30 kg (95% CI: 3.41, 5.20), 4.06 kg (95% CI: 2.99, 5.13) and 0.72 kg (95% CI: -0.07, 1.51), respectively, while among VLCD studies, the pooled change was 6.28 kg (95% CI: 6.08, 6.49), 4.22 kg (95% CI: 3.95, 4.50) and 2.24 kg (95% CI: 1.95, 2.52), respectively. CONCLUSIONS: Our results from both the systematic review and the meta-analysis suggest that ADF is an efficacious dietary method, and may be superior to VLCD for some patients because of ease of compliance, greater fat-mass loss and relative preservation of fat free mass. Head-to-head randomized clinical trials are needed to further assess relative efficacy of these two approaches. PMID- 27708850 TI - Facts and numbers on epidemiology and pharmacological treatment of heart failure with preserved ejection fraction. AB - Heart failure with preserved ejection fraction (HFpEF) is a major and growing public health problem. Epidemiologic studies demonstrated that heart failure (HF) can be clinically diagnosed in patients with normal or preserved left ventricular ejection fraction. These patients are therefore termed as having HFpEF. In the past, this was often called diastolic HF. Because of the permanent increase of the prevalence of HFpEF during the past decades, HFpEF now accounts for more than 50% of the total HF population. There are uncertainties and debates regarding the definition, diagnosis, and pathophysiology with the consequence that all outcome trials performed so far used criteria for inclusion and exclusion that were not consistent. These trials also failed to document improved prognosis. Recent smaller proof-of-concept or Phase II clinical trials investigating different pathophysiological approaches with substances such as the neprilysin inhibitor angiotensin receptor blocker- combination (LCZ 696), ranolazine, or ivabradine were successful to improve biomarkers, haemodynamics, or functional capacity. Future trials will need to document whether also prognosis can be improved. PMID- 27708849 TI - Highly purified eicosapentaenoic acid ameliorates cardiac injury and adipose tissue inflammation in a rat model of metabolic syndrome. AB - INTRODUCTION: n-3 Polyunsaturated fatty acids such as eicosapentaenoic acid (EPA), which are abundant in fish oil, have been shown to delay the onset of cardiovascular events. We previously established DahlS.Z-Leprfa/Leprfa (DS/obese) rats, which are derived from a cross between Dahl salt-sensitive and Zucker rats, as a model of metabolic syndrome. This study has now explored the influence of highly purified EPA on cardiac and adipose tissue pathophysiology in this animal model. MATERIALS AND METHODS: DS/obese rats were administered EPA (300 or 1,000 mg kg-1 d-1, per os) or vehicle from age 9 to 13 weeks. Homozygous lean (DahlS.Z Lepr+/Lepr+, or DS/lean) littermates were studied as controls. RESULTS: Whereas EPA had no effect on body weight, food intake or systolic blood pressure in DS/obese rats, it attenuated cardiac fibrosis, diastolic dysfunction, oxidative stress and inflammation in these animals. In addition, EPA did not affect insulin resistance but reduced adipocyte hypertrophy and inflammation in visceral fat of DS/obese rats. Moreover, EPA increased circulating levels of adiponectin as well as attenuated both the down-regulation of AMP-activated protein kinase phosphorylation and the up-regulation of phosphorylation of the p65 subunit of nuclear factor-kB in the heart of DS/obese rats. CONCLUSIONS: Treatment of DS/obese rats with EPA did not affect hypertension but reduced cardiac fibrosis and diastolic dysfunction, with the latter effects being accompanied by AMP activated protein kinase activation and inactivation of nuclear factor-kB signalling in the heart, possibly as a result of an increase in adiponectin secretion. EPA may be suitable for the treatment of cardiac injury associated with metabolic syndrome.

However, the underlying molecular mechanisms linking metabolic profiles and weight gain are largely unknown. METHODS: Here, we used semi-targeted metabolomics to assay 156 metabolites selected from 25 key metabolic pathways in plasma samples from 300 non-smoking healthy women identified from Mano-A-Mano, the Mexican American Cohort study. The study subjects were randomly divided into two cohorts: training (N = 200) and testing (N = 100) cohorts. Linear regression and Cox proportional hazard regression were used to assess the effect of body mass index (BMI) at baseline on metabolite levels and the effects of metabolites on significant weight gain during a 5-year follow-up. RESULTS: At baseline, we observed 7 metabolites significantly associated with BMI in both training and testing cohorts. They were Methyl succinate, Asparagine, Urate, Kynurenic acid, Glycine, Glutamic acid, and Serine. In further analysis, we identified 6 metabolites whose levels at baseline predicted significant weight gain during 5-year follow-up in both cohorts. They were Acetylcholine, Leucine, Hippuric acid, Acetylglycine, Urate, and Xanthine. CONCLUSIONS: The findings establish the baseline metabolic profiles for BMI, and suggest new metabolic targets for researchers attempting to understand the molecular mechanisms of weight gain and obesity. PMID- 27708851 TI - Heart failure, chronic obstructive pulmonary disease, and asthma: numbers, facts, and challenges. AB - Heart failure (HF), chronic obstructive pulmonary disease (COPD), and asthma are considered as major health problems. They affect 1-3%, 4-10%, and 8-19% of population, respectively, and frequently coexist. Pulmonary function testing and echocardiography are needed for reliable diagnosis, but in clinical practice, diagnosis often is based on history and disease self-reporting. Concomitant HF can be diagnosed in about 20% of patients with COPD, and at least 50% had systolic dysfunction. In patients with HF, prevalence of COPD is up to 35%, and less than 25% of patients have COPD GOLD stage III or IV. COPD is more severe in patients with HF with preserved ejection fraction. When HF and COPD coexist, hazard of death is increased for 39% but can even exceed the mortality in individual disease by threefold. In patients with acute deterioration, natriuretic peptides and lung ultrasound, along with other laboratory biomarkers and imaging, need to be implemented to differentiate underlying cause and to manage patients accordingly. COPD is not contraindication for beta-blockers, and if used, the risk of death is reduced by 31%; if indicated, cardio-selective agents can be used in asthma. Recent pan-European registry reported that about 90% of patients with HF receive beta-blockers, whereas dosing remains a large unmet need with only 17% being treated with target daily dose. Concurrent HF and COPD reduce the prescription of beta blockers threefold, which results in about 20% of patients actually being treated with beta-blockers. In COPD/asthma, beta agonists are strongly associated with new HF (relative risk of 3.41) and HF hospitalizations (odds ratio of 1.74). PMID- 27708852 TI - Facts and updates about cardiovascular non-coding RNAs in heart failure. AB - About 11% of all deaths include heart failure as a contributing cause. The annual cost of heart failure amounts to US $34,000,000,000 in the United States alone. With the exception of heart transplantation, there is no curative therapy available. Only occasionally there are new areas in science that develop into completely new research fields. The topic on non-coding RNAs, including microRNAs, long non-coding RNAs, and circular RNAs, is such a field. In this short review, we will discuss the latest developments about non-coding RNAs in cardiovascular disease. MicroRNAs are short regulatory non-coding endogenous RNA species that are involved in virtually all cellular processes. Long non-coding RNAs also regulate gene and protein levels; however, by much more complicated and diverse mechanisms. In general, non-coding RNAs have been shown to be of great value as therapeutic targets in adverse cardiac remodelling and also as diagnostic and prognostic biomarkers for heart failure. In the future, non-coding RNA-based therapeutics are likely to enter the clinical reality offering a new treatment approach of heart failure. PMID- 27708853 TI - Biological variation of the cardiac index in patients with stable chronic heart failure: inert gas rebreathing compared with impedance cardiography. AB - AIMS: In chronic heart failure (CHF), changes in cardiac function define the course of the disease. The cardiac index (CI) is the most adequate indicator of cardiac function. Interpretation of serial CI measurements, however, requires knowledge of the biological variation of CI. Because measurements of CI can be confounded by the clinical situation or the method applied, biological variation might be subject to the same confounders. METHODS AND RESULTS: We prospectively included 50 CHF patients who met rigid criteria for clinical stability. CI was measured by both inert gas rebreathing (IGR) and impedance cardiography (ICG) in weekly intervals over 3 weeks-each measurement performed at rest (IGRrest/ICGrest) and during low-exercise 10 Watt pedalling (IGR10W/ICG10W). Intra-class correlation coefficients (ICCs), reference change values, and minimal important differences of CI were determined for IGRrest, ICGrest, IGR10W, and ICG10W. Impedance cardiography and IGR showed moderate agreement at rest (20% (6 36)) and good agreement at 10 Watt (-4% (-23-16)). Depending on time interval, measurement modality for CI, and mode, ICC ranged between 0.42 and 0.78, ICC values for IGR were lower than those for ICG. Reference change value ranged between 3 and 15%, and minimal important difference ranged between 0.2 and 0.5 L/min/m2. Values for IGR were lower at rest and higher at 10 Watt than those for ICG. CONCLUSION: Non-invasive measurements of CI are stable over time. Measurement modalities for CI, however, are not interchangeable. Biological variation is less pronounced when obtained by ICG. The influence of low-level exercise on stability of CI depends on the measurement modality. PMID- 27708854 TI - Heterogeneous responses of systolic and diastolic left ventricular function to exercise in patients with heart failure and preserved ejection fraction. AB - AIMS: This study aimed to evaluate ventricular diastolic properties using three dimensional echocardiography and tissue Doppler imaging at rest and during exercise in heart failure with preserved ejection fraction (HFpEF) patients with borderline evidence of diastolic dysfunction at rest. METHODS AND RESULTS: Results obtained from 52 HFpEF patients (left ventricular ejection fraction >= 50%) identified on the basis of heart failure symptoms and E/E' values between 8 and 15 were compared with those obtained in 26 control patients with no evidence of cardiovascular disease. Mitral flow patterns, tissue Doppler imaging, and volume analysis obtained by three-dimensional echocardiography were performed at rest and during bicycle exercise. Diastolic compliance was indexed by the E/E' ratio and left ventricular end-diastolic volume [(E/E')/EDV]. There were no significant differences in end-diastolic volume (EDV), stroke volume (SV), or ejection fraction at rest between groups. In 27 of the 52 patients, E/E' increased during exercise (11.2 +/- 3.7 to 16.8 +/- 10.5), driven by a failure to augment early diastole (E'). This correlated with a fall in SV and was associated with an increase in the diastolic index (E/E')/EDV as a measure for LV stiffness (0.122 +/- 0.038 to 0.217 +/- 0.14/mL), indicating that impaired diastolic reserve (designated PEF-IDR) contributed to exercise intolerance. Of the 52 patients, 25 showed no changes in E/E' during exercise associated with a significant rise in SV and cardiac output, still inappropriate compared with controls. Despite disturbed early diastole (E'), a blunted increase in estimated systolic LV elastance indicated that impaired systolic reserve and chronotropic incompetence rather than primarily diastolic disturbances contributed to exercise intolerance in this group (designated PEF). CONCLUSION: Three-dimensional stress echocardiography may allow non-invasive analysis of changes in cardiac output that can differentiate HFpEF patients with an inappropriate increase or a fall in SV during exercise. Impaired systolic or diastolic reserve can contribute to these haemodynamic abnormalities, which may arise from different underlying pathophysiologic mechanisms. PMID- 27708855 TI - Levosimendan improves exercise performance in patients with advanced chronic heart failure. AB - AIMS: Cardiopulmonary exercise test (CPET) provides parameters such as peak VO2 and ventilation/CO2 production (VE/VCO2) slope, which are strong prognostic predictors in patients with stable advanced chronic heart failure (ADHF). The study aim was to evaluate the effects of the inodilator levosimendan on CPET in patients with ADHF under stable clinical conditions. METHODS AND RESULTS: We enrolled patients with ADHF (peak VO2 < 12 mL/min/kg) in a double-blind, placebo controlled protocol. Patients were randomly assigned to i.v. infusion of placebo (500 mL 5% glucose; n = 19) or levosimendan (in 500 mL 5% glucose; n = 23). Before and 24 h after the end of the infusion, patients underwent determination of New York Heart Association class, B-type natriuretic peptide (BNP), haemoglobin, serum creatinine, and blood urea nitrogen levels, as well as CPET, standard spirometry, and alveolar capillary gas diffusion. BNP showed no change with placebo (1042 +/- 811 to 1043 +/- 867 pg/mL), but it was decreased with levosimendan (1163 +/- 897 to 509 +/- 543 pg/mL, P < 0.001). No changes were observed for haemoglobin, creatinine, and blood urea nitrogen in either group. With levosimendan, a minor improvement was observed in spirometry measurements, but not in alveolar capillary gas diffusion. Peak VO2 showed a small, non significant increase with placebo (9.5 +/- 1.7 to 10.0 +/- 2.1 mL/kg/min, P = 0.12), and a greater increase with levosimendan (9.8 +/- 1.7 to 11.0 +/- 1.9 mL/kg/min, P < 0.005). The VE/VCO2 slope showed no change (44.0 +/- 11 vs. 43.4 +/- 10.3, P = 0.44), and a decrease (41.9 +/- 10 vs. 36.6 +/- 6.4, P < 0.001) in the placebo and in the levosimendan group, respectively. CONCLUSION: Levosimendan treatment significantly improves peak VO2 and reduces VE/VCO2 slope and BNP in patients with ADHF. PMID- 27708856 TI - Validation of the FEW16 questionnaire for the assessment of physical well-being in patients with heart failure with reduced ejection fraction: results from the CIBIS-ELD study. AB - AIMS: Patients with heart failure (HF) commonly suffer from severe impairment of quality of life (QoL). One main goal of HF treatment is improvement of QoL. Physical well-being is an essential component of QoL. To enable assessment of physical well-being in HF patients, we validated the FEW16 questionnaire in a prospective study with patients from the Cardiac Insufficiency Bisoprolol Study in ELDerly. METHODS AND RESULTS: In 127 HF patients (age 73 +/- 5.5 years, 72% male, 60% New York Heart Association class II, left ventricular ejection fraction 37 +/- 8.5%), we measured physical well-being (FEW16), QoL [36-Item Short-Form Health Survey (SF36)], and depressive symptoms [PRIME MD Patient Health Questionnaire German short version for depression (PHQ-D)] at baseline and two follow-up visits, and correlated FEW16 scores with QoL data and clinical parameters. FEW16 mean scores are 3.04 +/- 1.04 at baseline, 3.19 +/- 0.94 after 3 months, and 2.77 +/- 0.94 after 2-4 years. We assessed data quality, scale assumptions, and construct validity and reliability. Cronbach's alpha for subscales resilience: 0.84; ability to enjoy: 0.80; vitality: 0.88; inner peace: 0.87; total score: 0.95. Intraclass correlation coefficient (ICC) is 0.87 (95% CI 0.84-0.89, ICC (1.4). Pearson's correlations of FEW16 with SF36 and PHQ-D were significant. Six minutes walking distance and heart rate correlated significantly with the FEW16 total score. CONCLUSIONS: The FEW16 showed good reliability, internal consistency, and intraclass correlation. FEW16 scores correlated well with psychological and physical well-being (SF36) and clinical markers of exercise tolerance (6 min walk test and heart rate). Our results indicate a strong correlation of self-reported physical well-being with psychological factors. FEW16 values at baseline predicted the development of several aspects of QoL during beta-blocker up-titration. PMID- 27708857 TI - Risk stratification of patients with chronic heart failure using cardiac iodine 123 metaiodobenzylguanidine imaging: incremental prognostic value over right ventricular ejection fraction. AB - AIMS: Right ventricular (RV) systolic dysfunction has been shown to be an independent predictor of clinical outcome in patients with chronic heart failure (CHF), and cardiac metaiodobenzylguanidine (MIBG) imaging also provides prognostic information. We aimed to evaluate the long-term predictive value of combining RV systolic dysfunction and abnormal findings of cardiac MIBG imaging on outcome in CHF patients. METHODS AND RESULTS: We enrolled 63 CHF outpatients with left ventricular ejection fraction (EF) <40% in a prospective cohort study. At entry, RVEF was measured by radionuclide angiography. Furthermore, cardiac MIBG imaging was performed, and the cardiac MIBG washout rate (WR) was calculated. Reduced RVEF was defined as <=37%, and abnormal WR was defined as >27%. The study endpoint was unplanned hospitalization for worsening heart failure (WHF) and cardiac death. During a follow-up period of 8.9 +/- 4.3 years, 19 of 63 patients had unplanned hospitalization for WHF, and 19 of 63 patients had cardiac death. In multivariate analysis, both WR and RVEF were independent predictors of unplanned WHF hospitalization, while WR was also an independent predictor of cardiac death. A risk-stratification model based on independent predictors of unplanned WHF hospitalization separated the patients into those with low (absence of the predictors), intermediate (one of the predictors), and high (two or more of the predictors) risk of unplanned WHF hospitalization (P < 0.0001) or cardiac death (P = 0.0113). CONCLUSIONS: Cardiac MIBG imaging provides incremental value when it is used along with RV systolic dysfunction to predict clinical outcome in patients with CHF. PMID- 27708858 TI - Mid wall fibrosis on CMR with late gadolinium enhancement may predict prognosis for LVAD and transplantation risk in patients with newly diagnosed dilated cardiomyopathy-preliminary observations from a high-volume transplant centre. AB - BACKGROUND: Patients with newly diagnosed dilated cardiomyopathy (DCM) and advanced heart failure have a very high morbidity and mortality with an unpredictable clinical course. We investigated the role of cardiovascular magnetic resonance (CMR) imaging using late gadolinium enhancement (LGE) in this cohort of high-risk patients. We hypothesized that LGE has high prognostic value in primary DCM patients referred for possible transplantation/left ventricular assist device (LVAD) consideration. METHODS: Over 49 consecutive months, 61 consecutives DCM patients were referred for standard CMR(1.5T, GE) to interrogate the LV pattern, distribution, and extent of LGE (MultiHance, Princeton, NJ). Inclusion criteria for a primary non-ischaemic DCM and EF <45% were met in 31 patients. DCM patients were categorized into: (i) presence of midwall LV stripe (+Stripe) and (ii) absence of midwall stripe (-Stripe) groups. Primary outcome was defined by the composite of death, need for LV assist device (LVAD), and urgent orthotopic cardiac transplantation (Tx) during a 12-month follow-up period. Kaplan-Meier survival analysis was conducted grouping patients by +Stripe and -Stripe. RESULTS: There were no differences between groups for demographics, blood pressure, labs, baseline LVEF, NYHA class, or invasive haemodynamics. There were 18 patients (58%) with +Stripe. Nine events occurred: seven patients required urgent Tx and/or LVAD implantation and two patients died. The +Stripe categorization strongly predicted the need for LVAD, urgent Tx surgery, and death (log-rank = 9, P = 0.002). All the events occurred in the +Stripe patients with no MACE experienced in the -Stripe group. The -Stripe group experienced marked signs of improvement in LVEF (P = 0.01) at follow-up. LVEDD was predictive of need for LVAD/Tx and death by univariate analysis. Otherwise, no common clinical metric such as LVEF, LVEDV, RVEF, RVEDV, or any invasive haemodynamic parameter predicted MACE. CONCLUSIONS: The presence of +Stripe on CMR is strongly predictive of LVAD, transplant need, and death during a 12-month follow-up period in DCM patients in this proof of concept study. All -Stripe patients survived without experiencing any events. Incorporating CMR imaging into routine clinical practice may have prognostic value in DCM patients; indicating conservative management in low-risk patients while expectantly managing high-risk patients. PMID- 27708859 TI - Polypyrrole-incorporated conductive hyaluronic acid hydrogels. AB - BACKGROUND: Hydrogels that possess hydrophilic and soft characteristics have been widely used in various biomedical applications, such as tissue engineering scaffolds and drug delivery. Conventional hydrogels are not electrically conductive and thus their electrical communication with biological systems is limited. METHOD: To create electrically conductive hydrogels, we fabricated composite hydrogels of hyaluronic acid and polypyrrole. In particular, we synthesized and used pyrrole-hyaluronic acid-conjugates and further chemically polymerized polypyrrole with the conjugates for the production of conductive hydrogels that can display suitable mechanical and structural properties. RESULTS: Various characterization methods, using a rheometer, a scanning electron microscope, and an electrochemical analyzer, revealed that the PPy/HA hydrogels were soft and conductive with ~ 3 kPa Young's modulus and ~ 7.3 mS/cm conductivity. Our preliminary in vitro culture studies showed that fibroblasts were well attached and grew on the conductive hydrogels. CONCLUSION: These new conductive hydrogels will be greatly beneficial in fields of biomaterials in which electrical properties are important such as tissue engineering scaffolds and prosthetic devices. PMID- 27708860 TI - Whole-body MRI for full assessment and characterization of diffuse inflammatory myopathy. AB - BACKGROUND: Conventional magnetic resonance imaging (MRI) is a highly valuable tool for full assessment of the extent of bilateral symmetrical diffuse inflammatory myopathy, owing to its high sensitivity in the detection of edema which correlates with, and sometimes precedes, clinical findings. PURPOSE: To evaluate the use of whole-body (WB)-MRI in characterization and full assessment of the extent and distribution of diffuse inflammatory myopathy. MATERIAL AND METHODS: A prospective study on 15 patients presenting with clinical evidence of inflammatory myopathy. It included 4 boys/men and 11 girls/women (age range, 6-44 years; mean age, 25.5 years). 1.5 T WB-MRI was performed and the distribution and extent of disease severity was assessed according to muscle edema on STIR images. RESULTS: Four cases of dermatomyositis showed lower limb disease predilection with edema in gluteal, thigh, and calf muscles. The same finding was seen in one case with recurrent polymyositis and three cases with overlap myositis with systemic lupus erythematosus (SLE). Bilateral upper and lower limb myositis was demonstrated in three cases of polymyositis and one case of overlap myositis with scleroderma. Bilateral edema involving all scanned muscle groups was detected in three cases of polymyositis with paraneoplastic syndrome, SLE, and severe active dermatomyositis (including the neck muscles). CONCLUSION: WB-MRI is the diagnostic modality of choice for cases of inflammatory myopathy. It accurately detects the most severely affected muscles candidate for biopsy and provides a reliable baseline study for follow-up of disease progression as well as response to treatment. PMID- 27708862 TI - Dynamics shared by two related proinflammatory conditions, rheumatoid arthritis and metabolic syndrome. PMID- 27708861 TI - Prevalence of the metabolic syndrome in rheumatoid arthritis. AB - OBJECTIVE: Patients with rheumatoid arthritis (RA) experience a markedly increased prevalence of cardiovascular disease (CVD), but the causal factors have yet to be completely elucidated. Metabolic syndrome (MetS) is a cluster of risk factors of CVD and identifies additional cardiovascular risk beyond the sum of its individual components. In this study, we investigated the prevalence of MetS and its possible relationship with disease-related factors in patients with RA. MATERIAL AND METHODS: Fifty-two patients with RA and 30 age- and sex-matched healthy controls were studied. Adult Treatment Panel III of the National Cholesterol Education Program (NCEP-ATP III) and modified World Health Organization (WHO) criteria were used to define MetS. RA disease activity is assessed by the disease activity score of 28 joints (DAS28), and the functional status of patients was evaluated by Health Assessment Questionnaire (HAQ). RESULTS: Although there was no difference between groups regarding the frequency of MetS according to NCEP-ATP III criteria (17.3% and 6.5% in RA and control groups, respectively (p=0.158)) if modified WHO criteria were used, the prevalence of MetS was significantly higher in patients with RA (28.8%) than in controls (9.7%) (p=0.04). Central obesity and hypertension were found to be more frequent in patients with RA by both NCEP-ATP III and WHO criteria. RA patients with MetS had higher systolic and diastolic blood pressure, BMI and frequency of smoking than patients without MetS. Disease-related factors were similar in RA patients with or without MetS. CONCLUSION: The evaluation of patients with RA for MetS, which is a multidimensional risk factor of CVD, may be beneficial. PMID- 27708863 TI - Sonographic measurement of Achilles tendon thickness in seronegative spondyloarthropathies. AB - OBJECTIVE: To define the best cut-off value for identifying Achilles tendon thickening using ultrasound (US) in patients with spondyloarthropathies (SpA) and to assess its diagnostic utility in comparison with different cut-off values used in the literature. MATERIAL AND METHODS: One-hundred and one subjects (55 SpA patients and 46 age and body mass index ((BMI)-matched healthy controls (HC)) were investigated. US was performed using a MyLab70 US system (Esaote Biomedica, Genoa, Italy) with a linear probe (6-18 MHz). Three images per Achilles enthesis were stored and the antero-posterior thickness of the enthesis was measured at the level of the Achilles tendon deeper margin insertion into the calcaneal bone on the longitudinal median scan. The best cut-off value for each gender was determined by ROC curve analysis and compared to the other cut-off values in the literature: 1) 5.29 mm for both genders, and 2) 5.5 mm for females and 6.2 mm for males. The number of measurements exceeding the cut-off values as well as sensitivity (SE), specificity (SP), positive (PPV) and negative (NPV) predictive values were calculated. RESULTS: A significant difference was observed for Achilles enthesis thickness between genders (mean+/-SD: 4.6+/-0.7 mm in males vs. 4.0+/-0.8 mm in females, p<0.00) and between SpA patients and HC (mean+/-SD: 4.4+/-0.8 mm in SpA patients vs. 4.0+/-0.8 mm in HC, p<0.001). The ROC curve analysis revealed the best cut-off value to be 3.7 mm for females and 4.8 mm for males (SE: 43-70%, SP: 59-85%, PPV: 66-79%, NPV: 54-63%). Previously reported cut off values were found to have high SP (91-98%) but very low SE (2-11%). CONCLUSION: Achilles tendon thickness differs between genders; thus, it is crucial to refer to normal values that are specific for gender. High cut-off values, as previously suggested, showed very low SE in the current study. When Achilles enthesis thickening is used for the purpose of screening enthesitis in SpA patients, a lower cut-off value has a higher SE with slightly worse SP, PPV and NPVs. PMID- 27708864 TI - Evaluation of arterial stiffness with plasma GGT levels and pulse wave velocity measurement in patients with FMF. AB - OBJECTIVE: Pulse wave velocity (PWV) is a non-invasive technique used to evaluate the arterial elasticity, which is an early indicator of atherosclerosis. Lately, gamma glutamyl transferase (GGT) is considered a determiner of arterial stiffness (AS). In this study, we aimed to evaluate the relationship between GGT levels and AS with PWV in patients with Familial Mediterranean fever (FMF). MATERIAL AND METHODS: The study was conducted with 60 patients with FMF and 40 controls. Genetic analysis of the patients were performed. AS was assessed by PWV and, after the measurement of PWV, the presence of AS was determined. RESULTS: Mean PWV values and AS frequency were significantly higher in patients with FMF compared with the control group (p<0.001 and p=0.004, respectively). Mean GGT levels of FMF patients were higher than in the control group but the difference was not statistically different. In the correlation analysis, PWV and AS were positively correlated with FMF (r=0349, p<0.001; r=0.435, p<0.001, respectively). FMF duration and FMF were associated with GGT (r=0.300, p=0.02; r=0199, p=0.047, respectively). CONCLUSION: Increased PWV values in FMF patients may indicate arterial stiffness. These patients may be followed closely with PWV as an early indicator of atherosclerosis. Therefore, the cardiovascular risk can be determined in the early stages of disease and it may be possible to take necessary precautions. PMID- 27708865 TI - Serum salusin-alpha levels in systemic lupus erythematosus and systemic sclerosis. AB - OBJECTIVE: Systemic lupus erythematosus (SLE) and systemic sclerosis (SSc), chronic inflammatory diseases, demonstrate an increased incidence of cardiovascular manifestations and subclinical atherosclerotic disease. Salusin alpha is a novel bioactive peptide that suppresses the formation of macrophage foam cells, and its serum level is significantly lower in patients with angiographically proven coronary artery disease. The aims of the study were to assess serum salusin-alpha level and its potential association with the predictors of atherosclerosis in SLE and SSc. MATERIAL AND METHODS: The study included 20 SLE and 22 SSc patients and 23 healthy controls (HC). All of the participants were female. Tumour necrosis factor-alpha (TNF-alpha), IL-6 and salusin-alpha levels, homeostasis model assessment for insulin resistance (HOMA IR) index and common carotid intima-media thickness (IMT) were determined. RESULTS: Salusin-alpha levels were lower and the IMTs were higher in the SLE and SSc groups than in the HC group. The salusin-alpha level was correlated with neither the disease activity scores nor cytokine levels and IMT in the SLE and SSc groups, although it was correlated with triglyceride level in the SLE group (r=-0.564, p=0.012), and with HOMA-IR index in the HC group (r=0.485, p=0.019). CONCLUSION: The present preliminary study may support the idea that SSc leads to subclinical atherosclerosis, as in SLE. Moreover, it can be concluded that the decreased salusin-alpha levels in SLE and SSc may contribute to subclinical atherosclerosis. However, further studies with larger sample size are needed to demonstrate this contribution in SLE and SSc. PMID- 27708866 TI - Autonomic functions in acrocyanosis assessed by heart rate variability. AB - OBJECTIVE: To evaluate the autonomic activity of patients with acrocyanosis by using heart rate variability indices. MATERIAL AND METHODS: The study group consisted of 24 patients with acrocyanosis and the control group contained 22 sex and age-matched healthy subjects. All subjects underwent 24-hour Holter monitoring. Among the heart rate variability (HRV) parameters, time-domain and frequency-domain indices were analysed. RESULTS: The time-domain indices of HRV indicating global autonomic functions were found to be increased, and indices indicating parasympathetic activity showed a significant decrease in the patient group. Power-spectral analysis of HRV revealed that the low frequency and high frequency power were higher in the patient group than in controls. However, the ratio of Low Frequency/High Frequency was found to be lower in the patient group than in controls. CONCLUSION: In acrocyanosis, both sympathetic and parasympathetic systems seem to be disrupted. Therefore, we may conclude that acrocyanosis may be resulted of systemic autonomic imbalance rather than pure sympathetic over-activation. Also, these results suggest that acrocyanosis is not a localised disorder; on the contrary, it is associated with various abnormalities of the systemic autonomic nervous system. PMID- 27708868 TI - Mass-like lesions as a rare form of neuro-Behcet's disease: A case report and review of the literature. AB - Cerebral mass-like lesion (MLL) is a rare form of Neuro-Behcet's (NB) disease. There is currently no detailed knowledge on this issue in the literature. Our aim was to describe a Behcet's disease (BD) patient with MLL, followed by a clinical analysis in light of the available literature regarding BD patients who suffered from an MLL or tumefactive lesion in the brain. We conducted a review of the English literature to analyse data on MLL in BD. The Pub-Med, Web of Science, Proquest and Ovid databases were searched for articles or abstracts using the term "Behcet's disease" combined with one of the following terms: mass-like lesion, tumour-like lesion and tumefactive lesion. We compared clinical and laboratory features of BD patients with MLL with NB patients. We found 12 cases plus our case (6 male, 7 female; mean age: 40 years) with BD who developed MLL alongside BD. Five out of 13 BD patients (38%) had a history of BD before the onset of neurological symptoms. In 8 patients (62%), BD was diagnosed after the onset of neurological involvement. Headache, hemiparesis, dizziness, aphasia, nausea and vomiting were the presenting manifestations of NB patients with MLL. Genital ulceration, eye involvement, skin lesion and arthritis/arthralgia were less commonly reported in NB patients with MLL compared to NB patients without MLL. NB disease should be considered in the differential diagnosis of cerebral MLL even when other cardinal manifestations of BD are absent. Mucocutaneous manifestations, eye and joint involvement may be seen less often in these patients. PMID- 27708869 TI - Coexistence of systemic lupus erythematosus and ankylosing spondylitis: another case report and review of the literature. AB - The coexistence of systemic lupus erythematosus (SLE) and ankylosing spondylitis (AS) is very rare, and, to the best of our knowledge, there are only 8 reported cases in the English literature. Here, we present another case with the coexistence of these two diseases, and review the clinical and laboratory features of the previously reported cases. A 55 year-old female patient, with a diagnosis of SLE with locomotor, skin, renal and hematopoietic system involvement, which had been confirmed by relevant autoantibody positivity, and hypocomplementemia and biopsy-proven membranous lupus nephritis, was referred to our clinic suffered from typical inflammatory low-back pain after eight years of follow-up. Sacroiliac magnetic resonance imaging (MRI) confirmed the presence of bilateral active sacroiliitis with bone marrow oedema. HLA-B27 was positive and bilateral calcaneal spurs were also detected by conventional radiography. Therefore, the additional diagnosis of AS was made, eight years after the diagnosis of SLE. Inflammatory low-back pain typically responded to treatment with non-steroidal anti-inflammatory drugs. Including the present case, most of the reported cases of the coexistence of SLE and AS are female, and SLE generally precedes the occurrence of AS. The present case is also notable as the patient had both MRI confirmation of bilateral active sacroiliitis and HLA-B27 positivity. The coexistence of these two diseases with different genetic backgrounds in the same patient is much lower than expected based upon their prevalence in the general population. Although it has been suggested that the very rare combination of the susceptibility genes of each disease may explain the rarity of coexistence, epidemiological data concerning the genetic risks for the coexistence of SLE and AS are not available. PMID- 27708871 TI - Herpetic whitlow during immunosuppressive therapy for Wegener's Granulomatosis. AB - Skin involvement may occur in patients with Wegener's granulomatosis (polyangiitis with granulomatosis; WG) and is more frequent in the generalised form. However, when a patient with vasculitis develops digital ulceration, in addition to disease activation, other pathologies should be considered. One of them may be the herpetic whitlow mimicking paronychia. Here, we present a patient who developed herpetic whitlow during the course of immunosuppressive therapy due to WG. Just before the third course of cyclophosphamide therapy, she was re admitted to the outpatient clinic with the above-mentioned ulcerated lesions. On physical examination, there was erythema and a painful, crusted ulceration in the distal phalanx of the right index finger involving the proximal nail fold. Similar lesions were also present in her lower lip. Due to the absence of clinical and laboratory findings suggesting the activation of WG and the Tzanck smear result, which is compatible with herpes virus infection, we do not believe that WG was responsible for our patient's complaints. All of the patient's lesions completely disappeared following the interruption of immunosuppressive therapy. PMID- 27708872 TI - Endoscopic appearance of Henoch-Schonlein purpura. PMID- 27708870 TI - Thrombocytopenia caused by albendazole in a patient with Sjogren's syndrome: A case report. AB - Sjogren's syndrome (SS) is an autoimmune disease characterised by a chronic inflammatory response mainly localised to the lachrymal and salivary glands. Haematological abnormalities are common, although they rarely have clinical significance. Here, we report a patient with SS and thrombocytopenia caused by albendazole. Haematological abnormalities such as thrombocytopenia are seen in approximately 5-15% of SS patients; however, this disease is usually asymptomatic and can often be recovered to normal levels with corticosteroids. If it is not, we should keep in mind other reasons for the thrombocytopenia, such as drug use. PMID- 27708867 TI - Familial Mediterranean fever: An updated review. AB - Familial Mediterranean Fever (FMF) is a hereditary autoinflammatory disorder characterised by acute attacks of fever and serosal inflammation. FMF primarily affects Jewish, Armenian, Turkish, and Arab populations. The disease is accompanied by a marked decrease in quality of life due to the effects of attacks and subclinical inflammation in the attack-free periods. Untreated or inadequately treated patients run the risk of amyloidosis, which is an important cause of morbidity and mortality. In this review, the current information available on FMF is summarised. PMID- 27708873 TI - The clinical utility of anti-CCP antibodies in rheumatoid arthritis and psoriatic arthritis. PMID- 27708874 TI - Prevalence of hepatitis B and C infections in rheumatoid arthritis and ankylosing spondylitis: A multicenter countrywide study. AB - OBJECTIVE: Immunosuppressive therapies, especially tumor necrosis factor-alpha inhibitors, are frequently used in treatment of rheumatoid arthritis (RA) and ankylosing spondylitis (AS). These therapies can induce viral reactivation in concurrent hepatitis B virus (HBV)- or hepatitis C virus (HCV)-positive patients. On the other hand, the prevalence of HBV and HCV infections is not exactly known in RA and AS patients. The aim of this study was to investigate the prevalence of HBV and HCV infections in RA and AS patients. MATERIAL AND METHODS: A group of 1517 RA and 886 AS consecutive patients followed by six different rheumatology outpatient clinics of Turkey were recruited in this study. The prevalence of HBV surface antigen (HBsAg) and HCV antibody (anti-HCV) were retrospectively investigated. RESULTS: The mean age was 49.0+/-13.2 years in RA and 37.3+/-10.5 years in AS patients. HBsAg prevalence was 35 (2.3%) in RA and 27 (3%) in AS patients. Anti-HCV prevalence was 17 (1.1%) and 10 (1.1%), respectively. In the RA group, both HBsAg and anti-HCV positive patients were older than negative ones (p<0.05), and the highest prevalence was found in those 60-69 years (p<0.05). CONCLUSION: In previous national data, the prevalence of HBsAg has been reported as 3.99% and shown to increase with age. In this study we have found a lower HBV infection prevalence in both RA and AS patients according to Turkish national data. This result may explain by being younger age of our patients. In another conclusion, lower prevalence could be related to, joint complaints may less consulted to Rheumatologist in HBV positive. PMID- 27708875 TI - Mental health status can reflect disease activity in rheumatoid arthritis. AB - OBJECTIVE: A significant number of patients with rheumatoid arthritis (RA) link the start of illness with psychological trauma or severe stress. Impaired mental health (IMH), defined as depression and anxiety with psychoneuroimmunological factors, can play a significant role in RA. The main objective of this research was to investigate the mutual correlation of IMH and RA activity, estimated by the laboratory and clinical parameters in RA patients. MATERIAL AND METHODS: An open clinical prospective study that lasted for 6 months was designed. There were 72 patients included, 58 women and 14 men, aged 34 to 80 years and screened for mental health status. The study population was randomized following the Brief Symptoms Inventory (BSI) scale, comprised of 53 questions with a range from 0 (no symptoms) to 4 (severe). This mental test was done only once during the study. Following the results from the BSI scale, RA patients were divided into mentally stable and mentally unstable patients to investigate the influence of RA activity on mental health. The following laboratory and clinical parameters were analyzed: sex, age, erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), C reactive protein (CRP), anti-cyclic citrullinated peptide (anti-CCP) antibody, and disease activity score (DAS28). All RA patients did not express extra articular manifestations or Sjogren's syndrome. The chi-square test, ANOVA, Pearson's coefficient, and IBM Statistics - SPSS v19 were used. RESULTS: From a total of 72 RA patients, there were 44 mentally stable and 28 mentally unstable patients. All patients had either moderate or severe active disease. The only significant correlation of IMH and activity of RA was found in CRP and DAS28, but no significance was observed in ESR, RF, and anti-CCP. The DAS28 showed high disease activity with an average of 5.3 and CRP of 20.9 mg/L in patients with unstable mental health compared to stable mental health patients, where RA was associated with a moderate DAS average value of 4.35 and CRP of 14.1 mg/L. Depression and anxiety were found in all 28 (39%) RA patients. CONCLUSION: Mentally unstable RA patients correlate more with severe disease activity, while mentally stable patients express moderate disease activity. PMID- 27708876 TI - Heart rate variability in familial Mediterranean fever patients. AB - OBJECTIVE: Familial Mediterranean fever (FMF) is an autosomal recessive autoimmune disease, presenting with the attacks of fever and inflammation of serous membranes. One of the leading causes of death in autoimmune rheumatologic diseases is cardiovascular events. The purpose of this study is to evaluate the effects of FMF on the autonomic nerve and cardiovascular systems by measuring the indices of heart rate variability (HRV). MATERIAL AND METHODS: Thirty FMF patients and the same number of healthy volunteers were enrolled to the study. Standard deviation of all R-R intervals (SDNN), the square root of the sum of the square of the differences between successive R-R intervals (RMSSD), standard deviation of 5-minute mean values of R-R interval (SDANN), low frequency (LF), and high frequency (HF) were measured. RESULTS: Time domain indices (SDNN, SDANN, and RMSSD) were: 124.67+/-40.79, 129.87+/-36.43 (p=0.605); 11.43+/-38.41, 11.23+/ 38.98 (p=0.984); and 33.43+/-17.39, 38.17+/-12.8 (p=0.235) for FMF patients and controls, respectively, and similar in both groups. Frequency domain indices (HF, LF, and LF/HF) were: 290.41+/-290.25, 322.20+/-222.54 (p=0.639); 596.16+/-334.07, 805.80+/-471.00 (p=0.051); and 3.57+/-2.57, 3.05+/-1.40 (p=0.338) for FMF patients and controls, respectively, and similar in both groups. CONCLUSION: The HRV parameters were similar in both groups. However, studies including larger populations and using different methods are required to clarify if autonomic dysfunction exists in patients with FMF. PMID- 27708877 TI - Does isoniazid chemoprophylaxis increase the frequency of hepatotoxicity in patients receiving anti-TNF-alpha agent with a disease-modifying antirheumatic drug? AB - OBJECTIVE: The aim of this study is to determine the incidence of isoniazid (INH) related hepatotoxicity in patients with rheumatologic diseases receiving tumor necrosis factor-alpha (TNF-alpha) antagonists along with a disease-modifying antirheumatic drug (DMARD). MATERIAL AND METHODS: We have retrospectively evaluated 87 patients receiving anti-TNFalpha agents who were followed up between June 2005 and February 2010 at our rheumatology department. Sixty-one of 87 patients have received INH prophylaxis for 9 months for latent tuberculosis infection. RESULTS: A total of 61 (70.1%) of 87 patients used INH prophylaxis (Group I), while the remaining 26 (29.9%) (Group II) had not; 53 patients had used any DMARD in Group I, while 21 patients had used in Group II. No significant differences were found among Group I and II with respect to clinical features. When two groups were compared, in Group I, elevations of liver enzymes were detected in five patients (8.1%) who had normal baseline values. Among these patients, hepatotoxicity developed in two patients. Hepatotoxicity developed one patient in Group II (p=0.85). CONCLUSION: INH chemoprophylaxis was well tolerated in patients using anti-TNF-alpha agent and a DMARD. It seems not to be a strong risk factor for hepatotoxicity. However, comorbidities and other drugs used may be additional factors in the elevation of transaminases. PMID- 27708878 TI - The Frequency of anti-CCP antibodies in patients with rheumatoid arthritis and psoriatic arthritis and their relationship with clinical features and parameters of angiogenesis: A comparative study. AB - OBJECTIVE: Macrophage migration inhibitory factor (MIF) and vascular endothelial growth factor (VEGF), as crucial parameters of angiogenesis and inflammation, were evaluated to identify the role of cyclic citrullinated peptide antibodies (anti-CCP) during angiogenesis in rheumatoid arthritis (RA) and psoriatic arthritis (PsA). MATERIAL AND METHODS: A total of 145 patients with RA, 44 patients with PsA, and 73 healthy subjects were included in this study. The clinical features, total blood counts, and acute phase parameters of RA and PsA patients were recorded. Anti-CCP antibody, VEGF, and MIF levels were determined with enzyme-linked immunosorbent assay (ELISA). RESULTS: Anti-CCP positivity was significantly higher in the RA group (69%) than in both PsA (20.6%) and controls (8.2%) (p values<0.001). There was no difference between anti-CCP-positive and negative RA patients regarding the extra-articular manifestations (p>0.05). VEGF and MIF levels were similar in anti-CCP-positive and -negative RA patients (all p values>0.05). The specificity of anti-CCP antibodies for RA was found to be 87.2%. No relationship was found between anti-CCP antibody positivity and clinical features, disease activity, functional disability as assessed by health assessment questionnaire scores, and extra-articular manifestations. There was no relationship between parameters of angiogenesis and anti-CCP antibody positivity. Both RF and anti-CCP antibodies were observed to be positive in most patients with RA. CONCLUSION: Either RF or anti-CCP antibody was positive in a considerable proportion of our RA patients. Therefore, anti-CCP antibodies are important in the diagnosis of RF-negative patients who present with clinical findings of RA. PMID- 27708880 TI - A rare location of sacral tuberculosis: A report of three cases. AB - Tuberculosis remains one of the most common infectious diseases in the world. Vertebral tuberculosis is the commonest form of bone and joint tuberculosis; however, isolated sacral tuberculosis is rare. This atypical presentation may lead to a delay in diagnosis and treatment. We report three cases of sacral tuberculosis diagnosed in young women, aged 30, 23, and 35 years old, respectively. Lombosciatic pain was the main symptom in all cases. All patients had a biological assessment, plain radiographs, and CT scan. However, magnetic resonance imaging was done in only two cases. All patients underwent surgical sacral biopsy, and the diagnosis of tuberculosis was confirmed by histology in all cases. The evolution was satisfactory with the adjunction of antituberculous chemotherapy in all cases. Spinal tuberculosis should be the first and foremost differential diagnosis in the presence of atypical clinical and radiological features of a sacral lesion, particularly in developing countries. Early diagnosis and treatment could prevent or minimize the neurological morbidity in such cases. PMID- 27708881 TI - Nailfold capillaroscopy in Buerger's disease: A useful tool? AB - Thromboangiitis obliterans (TAO, or Buerger's disease) is a rare inflammatory vasculitis that commonly involves small and medium-sized arteries of the extremities of tobacco smokers between the ages of 25 and 50 years. Although the diagnosis is based on the clinical picture and angiographic findings, we studied the microvascular involvement by nailfold capillaroscopy. We evaluated by nailfold capillaroscopy 2 patients with Buerger's disease, at baseline and after 6 months of tobacco discontinuation and therapy with prostanoids. Both patients presented similar capillaroscopic abnormalities, resembling a scleroderma-like pattern. The microvascular rearrangement was significantly reduced after 6 months of evaluation. The capillaroscopic abnormalities shown in the two patients could be related to thromboangiitis obliterans, and nailfold capillaroscopy could be a useful tool to evaluate disease progression and the response to treatment. PMID- 27708879 TI - An old disease with new insights: Update on diagnosis and treatment of gout. AB - Gout is an acute and chronic inflammatory disorder associated with high morbidity and impaired quality of life. There has been a substantial increase in the prevalence and incidence of gout in recent years. Novel diagnostic and therapeutic options have provided new insights into the pathogenesis and management of hyperuricemia and gout in the last decade. This clinical review aims to summarize the diagnostic process and management of acute and chronic gout. PMID- 27708883 TI - Does epithelial-mesenchymal transition happen in rheumatoid joints?

PMID- 27708885 TI - Is there any relationship between season/weather and oral ulcer in Behcet's disease? AB - OBJECTIVE: Some rheumatic diseases are being influenced by weather conditions. We examined the relationship between oral ulcers and weather/season in Behcet's disease (BD) patients and evaluated the oral ulcers' characteristics by the patients' perspectives. MATERIAL AND METHODS: Patients with BD were evaluated using a self-questionnaire, including patients' clinical and demographical characteristics and detailed characteristics of oral ulcers and the association with season. RESULTS: The most common site of oral ulcers was the tongue (89%). Of 90 patients, there were predisposing factors in oral ulcers. Among patients with BD, 30 believed that seasonal variation aggravated their oral ulcers, especially in winter and autumn. CONCLUSION: The exacerbation of oral ulcers in patients with BD may be related to the seasons. The weather changes in our study are based on the patients' impression; these should be confirmed by objective findings and clinical assessment in further studies. PMID- 27708886 TI - The correlation between ferritin level and acute phase parameters in rheumatoid arthritis and systemic lupus erythematosus. AB - OBJECTIVE: In this study, we evaluated the relationship between ferritin levels and disease activation in rheumatoid arthritis (RA) patients. MATERIAL AND METHODS: We included 44 patients with RA, 20 patients with systemic lupus erythematosus (SLE), 25 patients with infection, 22 patients with malignancy, and 20 healthy control subjects. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), whole blood count, and serum iron parameters were determined in all cases. The joint findings in RA patients were recorded, and disease activity score (DAS) was calculated. In SLE patients, antinuclear antibody (ANA) and anti dsDNA titers and C3 and C4 complement levels were determined. SLE disease activity index (SLEDAI) score was calculated. RESULTS: Serum ferritin levels in the RA, SLE, and control groups were lower than those in the infection and malignancy groups (p<0.05). The ferritin levels in the RA group did not differ significantly from the SLE and control groups. In RA patients, serum ferritin level had a positive correlation with ESR, CRP, RF, platelet count, and DAS score and had a negative correlation with hematocrit (all p values <0.05). In SLE patients, on the other hand, serum ferritin had a positive correlation with ANA, anti-dsDNA, and SLEDAI (all p values <0.05). According to DAS, ferritin level in inactive RA patients was lower than that in active RA patients. When transferrin saturation was considered, iron deficiency anemia was a quite frequent finding in both active and inactive RA patients. CONCLUSION: Interestingly, we observed that ferritin level in RA patients was similar to the control group; however, it was a good parameter of disease activation. This is because a reduction in storage iron and resultant iron deficiency anemia are very common in RA patients. PMID- 27708887 TI - Inflammatory myopathies: One-center experience. AB - OBJECTIVE: Our aim was to report our experience with inflammatory myositis. MATERIAL AND METHODS: In total, 60 patients were evaluated retrospectively, and 43 of them (71.7%) were female. The median age was 45 (17-81). Of all patients, 33 (55%) were diagnosed as polymyositis, 22 (36.6%) as dermatomyositis (classical, amyopathic, and malignancy-associated), and 5 (8.33%) as undifferentiated myositis. The 3 patients with malignancy-associated dermatomyositis had lung cancer, nasopharyngeal carcinoma, and endometrial cancer. Two patients with polymyositis had a history of low-grade gastric mixed tumor and thymoma but were diagnosed 7 and 12 years ago, and no recurrences have been reported during the routine controls. RESULTS: All patients, other than two with malignancy-associated dermatomyositis, were treated via immunosuppressive agent, and the third patient with lung cancer was diagnosed later and gave up immunosuppressive therapy. Thirty-nine (65%) of the patients were treated via oral low-dose steroid, and 19 (31.7%) were treated via intravenous high-dose pulse steroid therapy. All patients were treated with steroid, which was tapered by time, and 23 (38.3%) were treated with azathioprine, 6 (10%) were treated with cyclophosphamide, 3 (5%) were treated with methotrexate, and 6 (10%) were treated with isolated steroid therapy at the time of diagnosis. The median follow-up period was 37 (2-135) months. Six patients (10%) have died-3 due to myocardial infarction, 1 due to septic shock, 1 due to malignancy, and 1 with an unknown reason. The 5-year survival rate was 76.9%, and the 10-year survival rate was 40%. CONCLUSION: Other than the high ratio of PM in our series, all other results were compatible with the literature. We faced few resistant diseases; therefore, biologic agents were used rarely. PMID- 27708888 TI - Neutrophil lymphocyte ratio can be a valuable marker in defining disease activity in patients who have started anti-tumor necrosis factor (TNF) drugs for ankylosing spondylitis. AB - OBJECTIVE: Neutrophil lymphocyte ratio (NLR) has emerged as a valuable and reliable method for follow-up of systemic inflammatory disease. We herein aimed to evaluate the role of NLR in the clinical follow-up of inflammation and also to compare its relationship with other measures, such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). MATERIAL AND METHODS: A total of 35 active ankylosing spondylitis (AS) and 38 healthy volunteers were included in the study. The patient group was enrolled for treatment with one anti-tumor necrosis factor (TNF) drug. Total blood count, ESR, CRP, and BASDAI score were obtained before and 3 months following the treatment. NLR was found with a mathematical calculation of the ratio of neutrophils with lymphocytes. RESULTS: The mean NLR value of the control group and patients was 1.90+/-0.89 and 2.67+/-1.17, respectively (p<0.05). After a 3-month course of treatment, the patient group had a mean NLR value of 1.8+/-0.7, which was significantly lower than pretreatment values (p<0.001). The post-treatment mean ESR, CRP, and BASDAI scores were significantly lower than mean baseline scores (p<0.001, p=0.007, p<0.001, respectively). Also, NLR was found to be correlated with BASDAI, ESR, and CRP (r=0.388, p<0.001; r=0.455, p<0.0001; and r=0.3389, p<0.005, respectively). CONCLUSION: Neutrophil lymphocyte ratio could be a reliable and easily accessible method for follow-up of patients with AS. PMID- 27708889 TI - Body composition in patients with rheumatoid arthritis is not different than healthy subjects. AB - OBJECTIVE: Rheumatoid arthritis (RA) is associated with an increased risk of cardiovascular disease (CVD). Increased body fat, particularly its central distribution, is a well-known risk factor for CVD. A change in body composition in RA has been described previously. However, in most of these studies, age- and sex- but not body mass index (BMI)-matched controls were used. The aim of this study was to evaluate body composition in RA patients and compare it with age-, sex-, and BMI-matched controls. MATERIAL AND METHODS: Sixty-five RA patients (55 females and 10 males; mean age 54.9 +/- 10.8) and 31 healthy controls (25 females, 6 males; 53.8+/-8.6) were included in this study. Mean disease duration was 9.2+/-9.6 years. Body composition was assessed by anthropometric methods (skinfold thicknesses, body circumferences), bioimpedance analysis, and dual energy X-ray absorptiometry (DXA). Visceral adipose tissue (VAT) was assessed with computed tomography. RESULTS: There were no significant differences for total body fatness, regional fat distribution, and total body water and fat-free mass between RA patients and control subjects. Bone mineral content (BMC), assessed by DXA, was significantly lower in RA patients (p=0.004). Clinical disease activity indices and steroid treatment do not affect soft tissue body composition or BMC. CONCLUSION: At least some RA patients do not have soft tissue composition alterations and may have similar health risks in comparison with subjects with similar age, sex, and total adiposity. PMID- 27708891 TI - Bilateral coxitis in scleroderma-polymyositis overlap syndrome. AB - Joint manifestations in scleroderma (Scl) and polymyositis (PM) are dominated by inflammatory arthralgia. Arthritis is less common and preferentially affects the hands, wrists, knees, and ankles. Involvement of the hip has been rarely reported in the literature. We report a case of coxitis diagnosed in a patient suffering from scleroderma-polymyositis overlap syndrome successfully treated by ultrasound guided infiltration of triamcinolone hexacetonide. PMID- 27708892 TI - Presentation of three cases followed up with a diagnosis of Felty syndrome. AB - An effective treatment strategy for Felty syndrome (FS) has not been developed so far. In this article, three cases with FS, who responded to different treatment modalities, have been presented. Case 1 was a 52-year-old male patient who initially received methotrexate, and then, he was switched to granulocyte colony stimulating factor (G-CSF) and cyclosporine treatment when his neutropenia was further deteriorated. The patient needed monthly doses of G-CSF for nearly 6 months, and his steroid dose was increased. Afterwards, his neutropenia improved with cyclosporine, methotrexate, and hydroxychloroquine combination treatment. Case 2 was a 78-year-old female patient who was started on leflunomide, hydroxychloroquine, and 60 mg methylprednisolone. Case 3 was a 69-year-old female patient who was first treated with 32 mg methylprednisolone, G-CSF, and then with cyclosporine. Neutropenia of both patients improved, and their health status normalized at 2 months. Different treatment strategies have been tried for the management of FS; disease-modifying anti-rheumatic drugs have been used successfully alone or in combination with G-CSF. As seen in the last case, it should be kept in mind that patients can present predominantly with symptoms of infection or hematologic disorders. PMID- 27708890 TI - Skin imaging in systemic sclerosis. AB - Fibrotic involvement of the skin is a cardinal feature of systemic sclerosis (SSc). The extent of skin involvement is associated with internal organ involvement, coinciding with more severe disease course and poor prognosis. A palpation-based semi-quantitative score, the modified Rodnan skin score, is widely used for the assessment of skin involvement, but it is entailed by significant limitations. More objective approaches to measure skin involvement employing imaging have been explored continuously in the past decades and are currently advancing. Here, we review the use of different imaging techniques for the assessment of skin involvement in patients with SSc, focusing mainly on ultrasound, magnetic resonance imaging, and optical coherence tomography. PMID- 27708893 TI - An unusual manifestation in a patient with adult-onset Still's disease: Minimal glomerular lesion. AB - Adult-onset Still's disease (AOSD) is a multisystem inflammatory disease of unknown etiology. It is characterized by arthritis, hectic fever, transient rash and visceral lesions such as pleuropericarditis, lymphadenopathy and hepato splenomegaly. Although kidney involvement may appear in some cases of AOSD, minimal glomerular lesion (MGL) has not been described. We describe a female patient, who presented with multisystemic manifestations, including high spiking fever, arthralgias, striking hyperferritinemia, and proteinuria. Renal biopsy showed classic MGL. A diagnosis of AOSD was made on the basis of Yamaguchi's criteria. The patient was treated with steroids, resulting in remission of the rheumatological condition closely paralleled by remission of proteinuria, thereby strongly suggesting a causative link between AOSD and MGL in this patient. Renal involvement in the AOSD was rarely reported in the literature. MGL may be a cause of unexplained proteinuria in AOSD. In this situation, renal biopsy is necessary to establish a definitive diagnosis. PMID- 27708894 TI - Etanercept in the treatment of SAPHO syndrome: Which place? AB - Synovitis, acne, pustulosis, hyperostosis, and osteitis syndrome (SAPHO) is a rare disease combining skin, bone, and joint manifestations. Its treatment remains a debated issue in the absence of a valid therapeutic strategy. The experience with tumor necrosis factor alpha (TNF alpha)-blocking agents is still small but encouraging. This therapy is reserved for refractory cases. The most commonly used agent is infliximab. Only few cases treated by etanercept have been reported in the literature. We report a new case treated by this biologic therapy and discuss its place in the treatment of SAPHO syndrome. A 30-year-old male, with a history of left clavicular osteitis that required surgical bone biopsy to rule out infection and malignancy, was admitted to the rheumatology department because of recurrent anterior chest pain, lower limb arthralgia, and sacroiliac pain. Laboratory findings revealed an inflammatory syndrome. Conventional radiography and computed tomography (CT) scan of the sternocostoclavicular region showed sclerosis and hyperostosis of the left clavicle. Right sacroiliitis was diagnosed based on the radiographic findings. Moreover, the patient reported palmoplantar pustulosis, thereby strengthening the diagnosis of SAPHO syndrome. As conventional treatment based on methotrexate, corticosteroids, and zoledronic acid was not effective, etanercept was initiated with good and rapid clinical and biological improvement. The diagnosis and treatment of SAPHO syndrome are challenging due to the heterogeneity of symptoms and unknown pathogenesis. Etanercept can be an effective therapy, especially in refractory cases. Further studies are needed in order to establish a therapeutic strategy. PMID- 27708896 TI - Inflammatory back pain due to heterotopic ossification.

PMID- 27708897 TI - Articular and abarticular manifestations in type 2 diabetes mellitus. AB - OBJECTIVE: Diabetes mellitus (DM), a worldwide high-prevalence disease, is associated with a large variety of rheumatic manifestations. It affects the connective tissues in many ways and causes alterations in the periarticular and the musculoskeletal systems. In most cases, these manifestations are associated with functional disability and pain, affecting the quality of life of the diabetic patient. The aim of our study is to review the different articular and abarticular manifestations in diabetic patients and the associated factors of these rheumatic manifestations. MATERIAL AND METHODS: A cross-sectional study that includes all patients suffering from type 2 DM who present with articular or abarticular manifestations. RESULTS: We included 116 diabetic patients presenting with articular or abarticular manifestations. Our study showed four important findings. First, a large variety of articular and abarticular manifestations were present in patients with type 2 DM. Second, osteoarthritis (OA) of the knee was the most frequent articular manifestations. It was seen in 49% of our patients. Third, the most common manifestations in diabetic Moroccan patients were carpal tunnel syndrome (CTS), adhesive capsulitis of the shoulder, and diabetic cheiroarthropathy (29%, 23%, and 16%, respectively). Fourth, there was a significant association between vascular complications and the development of articular and abarticular manifestations. CONCLUSION: This study shows that the articular and abarticular manifestations in diabetic Moroccan patients are dominated by CTS, adhesive capsulitis of the shoulder, and diabetic cheiroarthropathy, with a significant association between vascular complications and the development of some of these manifestations. PMID- 27708898 TI - Potential role of interleukin-18 in patients with rheumatoid arthritis-associated carotid intima-media thickness but not insulin resistance. AB - OBJECTIVE: Plasma interleukin-18 (IL-18) has been reported to be associated with homeostasis model assessment of insulin resistance (HOMA-IR). It also has been described as one of the factors that, in addition to insulin resistance, may also contribute to atherosclerosis. Parameters of systemic inflammation are also significantly associated with circulating IL-18. Our objective was to investigate whether IL-18 is associated with insulin resistance and atherosclerosis in patients with rheumatoid arthritis (RA) in which accelerated atherogenesis develops. MATERIAL AND METHODS: Fifty-one female RA patients and 30 female controls were enrolled in the study; 31 of them were without disease-modifying antirheumatic drug (DMARD) treatment and had a relatively short disease duration. Disease activity was assessed by Disease Activity Score (DAS) 28 index. HOMA-IR method was used to detect insulin resistance. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), fasting plasma glucose (FPG), insulin, tumor necrosis factor alpha (TNF-alpha), and IL-18 levels were evaluated. Also, carotid intima-media thickness (cIMT) was measured. RESULTS: There were no differences between patients and the control group according to age, sex, and body mass index. ESR, CRP, insulin, FPG, HOMA-IR, TNF-alpha, IL-18 levels, and cIMT measurements were significantly high in the patient group. HOMA-IR and cIMT measurements were similar and high in both the DMARD and non-DMARD patient groups. HOMA-IR correlated with TNF-alpha (r=0.308, p=0.028), but no correlation was found between IL-18 and HOMA-IR. However, IL-18 was correlated positively with cIMT (r= 0.318, p=0.028) and negatively with BMI (r=-0.360, p=0.01). CONCLUSION: IL-18 is associated with atherosclerosis in RA patients. However, no significant relation was found with insulin resistance. IL-18 may be a marker for early evaluation of atherosclerosis in RA patients. PMID- 27708899 TI - Serum lipid changes and insulin resistance in familial Mediterranean fever. AB - OBJECTIVE: Inflammation is known to alter lipid profiles and to induce insulin resistance. This study was planned to test the hypothesis that familial Mediterranean ferver (FMF) patients and their first-degree asymptomatic relatives may have lipid profile changes and/or insulin resistance, similar to other inflammatory diseases. MATERIAL AND METHODS: We studied 72 FMF patients, 30 asymptomatic first-degree relatives, and 75 healthy controls. Fasting and 2-hour postprandial glucose, insulin, apolipoprotein (Apo) A1, Apo B, acute phase reactants, and lipid profiles of all subjects were studied. Insulin resistance was determined by the HOMA (Homeostasis Model Assessment) index. RESULTS: There was no difference between the groups with regard to sex, mean systolic and diastolic blood pressure, body mass index, smoking status, fasting and postprandial 2-hour glucose, insulin, acute phase reactants, and HOMA index levels. High-density lipoprotein cholesterol (HDL-C) levels were similar between FMF patients and FMF relatives (48.9+/-12.4 mg/dL vs 49.3+/-13.8 mg/dL; p=NS), and both were lower than controls (48.9+/-12.4 mg/dL vs 59.6+/-15.1 mg/dL; p<0.001 and 49.3+/-13.8 mg/dL vs 59.8+/-15.1 mg/dL; p=0.001, respectively). Apo A1 levels in FMF patients and asymptomatic first-degree FMF relatives were both lower than in controls, similar to the HDL-C levels (126.1+/-25.7 mg/dL vs 151.2+/-31.4 mg/dL; p<0.001 and 129.5+/-29.0 mg/dL vs 151.2+/-31.4 mg/dL; p=0.002, respectively). TG levels were significantly higher in FMF relatives as compared to controls (113.4+/-53.6 mg/dL vs 97.1+/- 54.9 mg/dL; p=0.025). CONCLUSION: Low HDL-C and low Apo A1 levels are found in FMF patients and their first-degree asymptomatic relatives. Low-grade inflammation caused by MEFV mutations may be responsible for these lipid profile changes. PMID- 27708900 TI - New platelet indices as inflammatory parameters for patients with rheumatoid arthritis. AB - OBJECTIVE: To test new platelet indices for patients with rheumatoid arthritis (RA) as new acute phase reactants. MATERIAL AND METHODS: In total, 120 patients with RA and 40 patients in the control group were analyzed. A DAS 28 score over 2.6 was accepted as active disease, and a DAS 28 score lower than 2.6 was accepted as under remission. Platelet distribution width, plateletcrit, and mean platelet volume were analyzed for three groups: patients with active RA, patients under remission, and the control group. RESULTS: There were 72 patients with active disease and 48 patients under remission. The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), mean platelet volume (MPV), plateletcrit (PTC), and platelet distribution width (PDW) scores were all statistically different among groups. In our data, PTC was found to be a positive acute phase reactant and others were negative acute phase reactants for patients with RA. CONCLUSION: These new indices are cheap, widely available, and useful parameters for routine clinical rheumatology practice. PMID- 27708901 TI - Combined infliximab and methotrexate treatment improves the depressive state in rheumatoid arthritis patients more effectively than methotrexate alone. AB - OBJECTIVE: Rheumatoid arthritis (RA) patients have a greater depressive tendency than normal subjects, and infliximab is known to provide quick therapeutic effects and to have high bioavailability for RA. We therefore investigated whether the depressive state of RA patients would be improved by infliximab. MATERIAL AND METHODS: The Self-Rating Depression Scale (SDS) was used to evaluate 34 RA patients before and 14 or 30 weeks after inflixi mab treatment using the SDS and Disease Activity Score (DAS) 28. The SDS and DAS28 results before and after treatment were compared. RESULTS: We also included 42 cases treated with methotrexate as the control group. The SDS decreased in both groups, and the intraindividual vari ability was p<0.001, indicating that the drugs had significantly different effects on the SDS. The DAS tended to decrease in both groups, but the intraindividual variability was p=0.199, indicating no difference between the two drugs. CONCLUSION: This study is a preliminary study, but the data suggest that infliximab may reduce RA disease activity and improve the depressive state. PMID- 27708902 TI - On matters of causation in personal injury cases: Considerations in forensic examination. AB - Rheumatologists are often called to be independent examiners of injured claimants and to address the question: "What is causing the injured person's symptoms?" This article deals with the legal principles that arise in these cases, including causation, convenient focus, secondary gain, and thin skull rules. We shall first set out two hypothetical scenarios of personal injury cases that set the scene for a discussion of legal principles in personal injury law. With the same two scenarios of personal injury in mind, we shall review the legal principles and the biopsychosocial models of the illnesses concerned and consider the importance of examiners going beyond diagnostic labels towards a more in-depth analysis of illness factors and mechanisms that in turn assist the trier of facts. PMID- 27708903 TI - Acute coronary syndrome in Behcet's disease caused by a coronary artery aneurysm and thrombosis. AB - Behcet's disease (BD) is a multisystemic vasculitis that can involve vessels of all sizes and is characterized by recurrent oral and genital ulcers with variable manifestations affecting the skin, eyes, and central nervous and musculoskeletal systems. Vascular involvement in BD is reported to be up to 40% in different series. The abdominal and thoracic aorta and pulmonary and femoral arteries are the most commonly involved arteries. However coronary arteries are rarely affected. Herein, we present a 29-year-old man who was consulted with progressive severe chest pain of 3 days in duration to our clinic. The patient was diagnosed with BD with mucocutaneous symptoms and a positive pathergy test 1 year ago and was in clinical remission for the last 6 months. At the first evaluation in the emergency department, the patient's vital signs were stable, whereas he had elevated troponin T levels with a normal electrocardiogram and hypokinetic areas in the apex of the heart in the echocardiography. Conventional and computed tomography coronary angiography revealed aneurysms and intramural thrombosis in the left anterior descending and right coronary arteries. Although ischemic symptoms and signs improved with anticoagulant and antiaggregant therapies, coronary aneurysms were observed to increase in size. Immunosuppressive (IS) treatment was started with pulse intravenous corticosteroids and cyclophosphamide. Because of the high re-stenosis risk, stents were not applied to the affected vessels during the acute thrombosis period. During routine investigations, an in situ pulmonary thrombosis was also detected bilaterally in the peripheral pulmonary arteries. In conclusion, coronary artery aneurysm is a rare and poor prognostic manifestation of BD. The treatment protocol for these aneurysms is not well clarified. IS therapies are definitely indicated, but the role of anticoagulants and invasive vascular interventions is controversial. PMID- 27708904 TI - Spontaneous patellar tendon rupture in a case followed up for diagnosis of systemic lupus erythematosus. AB - Spontaneous patellar tendon rupture is a rare condition that usually occurs secondary to conditions, such as rheumatoid arthritis, systemic lupus erythematosus (SLE), and use of steroids and fluoroquinolones. This paper presents a full-thickness patellar tendon rupture detected with magnetic resonance imaging, which was performed due to pain and swelling that started spontaneously on the front side of the left knee without a history of any trauma, of a 35-year-old male patient who had been followed up for a diagnosis of SLE for approximately 4 months and who had started taking methylprednisolone 4 mg/day 4 months prior, used it for 1 month, and then stopped using it. In patients who are followed up for a diagnosis of SLE, it should be kept in mind that there is a risk of developing a spontaneous tendon rupture secondary to chronic inflammation and use of corticosteroids. PMID- 27708905 TI - Chondrodermatitis nodularis chronica helicis in a patient with systemic sclerosis associated with primary biliary cirrhosis (Reynolds syndrome): A case report. AB - Chondrodermatitis nodularis chronica helicis is a rare non-neoplastic inflammatory and degenerative process of the external ear, characterized by necrobiotic changes in the dermis that extend down to the perichondrium. This condition has been occasionally reported in patients with limited cutaneous systemic sclerosis but not in those with concomitant primary biliary cirrhosis; this association is known as Reynolds syndrome. We report a 70-year-old woman diagnosed with primary biliary cirrhosis at age 47 and with limited cutaneous systemic sclerosis at age 54 who developed a painful ulcerated nodule on the helical rim of the left ear shortly after the last diagnosis. The lesion was excised because of the suspicion of malignancy, but the histopathology was consistent with chondrodermatitis nodularis chronica helicis. Although this condition is infrequent, it is necessary to know, because it may occur in patients with systemic sclerosis and be mistaken for neoplasms, such as basal cell and squamous cell carcinoma, and these patients have an increased risk for the development of skin malignancies. PMID- 27708906 TI - A successful treatment of juvenile idiopathic arthritis with rituximab: A report of two cases. AB - Juvenile idiopathic arthritis (JIA) is defined as arthritis of unknown cause that starts before 16 years of age and lasts at least 6 weeks. It is the most common chronic inflammatory disease in childhood and often persists through adulthood and can lead to severe disability. Biologics are an important therapeutic option for treating patients with JIA. The efficiency of rituximab has not been proven for this indication. Its use has rarely been reported in the literature. We report two new cases of severe and refractory polyarticular JIA with positive rheumatoid factor affecting two African females aged 17 and 18 years successfully treated with rituximab. According to our experience, the use of rituximab in the treatment of JIA, especially in severe polyarticular forms with positive rheumatoid factor, might be a good alternative. Larger therapeutic trials should be conducted in this direction in order to prove the effectiveness of this biotherapy for this indication. PMID- 27708907 TI - Severe candida laryngitis in a patient with rheumatoid arthritis treated with adalimumab. AB - Rheumatoid arthritis is a chronic erosive rheumatic disease that can present with polyarticular involvement. Anti-TNF-alpha drugs are used in cases that are resistant to traditional disease-modifying antirheumatic drugs (DMARDs). Anti-TNF alpha drugs are groundbreaking drugs, the efficacy of which has been proven in the treatment of rheumatoid arthritis. However, the data concerning safety remain limited and contradictory. The risk of tuberculosis reactivation, various infections, as well as lymphoproliferative disease and/or secondary malignancy is a matter of discussion. In this report, we report a 52-year-old male patient using adalimumab for active rheumatoid arthritis who presented to our polyclinic with generalized mouth and throat sores, hoarseness, and swallowing difficulty. Candida laryngitis was detected in the laryngoscopy and culture samples. Adalimumab was discontinued, and the infection was controlled with anti-fungal treatment. PMID- 27708908 TI - A case of neutrophilic dermatosis who develop palpable purpura during the use of montelukast. AB - In this case report, we present a female patient with neutrophilic dermatosis (ND) occurring as palpable purpura after using montelukast. Neutrophilic dermatoses (NDs) are characterized by skin lesions in which mature neutrophils are predominantly located in the epidermis and dermis in the absence of any infective pathology. Classification of the NDs is based upon the recognition of clinical and pathologic features, as well as the identification of associated diseases, like Sweet's syndrome, pyoderma gangrenosum, generalized pustular psoriasis, and Behcet's disease. Cutaneous findings in NDs are variable and can include vesiculopustules, plaques, nodules, or ulcerations. Drug-induced NDs are not uncommon, but ND with palpable purpura is uncommon. The current patient appeared with a rare presentation as palpable purpura without vasculitis regarding ND. It is important that this is the first case report.

PMID- 27708910 TI - Role of PET/CT in the diagnosis of large vessel vasculitis in a patient with systemic inflammatory response syndrome. PMID- 27708911 TI - Is early diagnosis of pulmonary arterial hypertension possible in inflammatory rheumatic diseases? Experience from a single center in Turkey. AB - OBJECTIVE: Pulmonary arterial hypertension (PAH) is a devastating complication of inflammatory rheumatic diseases. The aim of this study was to determine the role of screening for the early diagnosis of pulmonary hypertension (PH) in inflammatory rheumatic diseases. MATERIAL AND METHODS: Data of patients with inflammatory rheumatic diseases and PH who had no obvious cause of PH and who were evaluated by Working Group for Pulmonary Hypertension in Hacettepe University were investigated retrospectively. All patients with inflammatory disease were evaluated by right heart catheterization (RHC) to check if they had systolic pulmonary arterial pressure (sPAP) >=40 mmHg and/or symptoms related to PH unless explained by other causes. RESULTS: RHC was performed in 47 patients with inflammatory rheumatic diseases and PH out of 50 patients who were to be evaluated by RHC based on clinical and Doppler echocardiographic findings. There was a positive correlation between sPAP estimated by Doppler echocardiography and sPAP determined by RHC in patients with inflammatory rheumatic diseases (r=0.66; p<0.001). The mean pulmonary arterial pressure (mPAP) was found to be <25 mmHg in 27.7% of the patients. New York Heart Association functional capacity (NYHA FC) was class III or IV in 79.0% of the patients with PAH. PAH was more frequent in patients with NYHA FC III-IV compared with patients with NYHA FC I-II [58.7% (15) patients vs. 19.0% (4) patients; p=0.009]. CONCLUSION: In this study, approximately 80% of the patients with inflammatory disease-associated PAH were diagnosed late in NYHA FC III or IV. There are still unresolved issues in the diagnosis and treatment of PH in inflammatory diseases. Collaboration and multidisciplinary approach are the key points to overcome the challenges in this field. PMID- 27708912 TI - Humor in systemic lupus erythematosus. AB - OBJECTIVE: Humor has neurophysiological effects influencing the release of cortisol, which may have a direct impact on the immune system. Laughter is associated with a decreased production of inflammatory cytokines both in the general population and in rheumatoid arthritis (RA). Our objective was to explore the effects of humor on serum cytokines [particularly interleukin-6 (IL-6)] and cortisol levels in systemic lupus erythematosus (SLE), after a standard intervention (120 min of visual comedy). MATERIAL AND METHODS: We enrolled 58 females with SLE from consecutive patients assessed in the Montreal General Hospital lupus clinic. The subjects who consented to participate were randomized in a 1:1 ratio to the intervention (watching 120 min of comedy) or control group (watching a 120 min documentary). Measurements of cytokine and serum cortisol levels as well as 24-h urine cortisol were taken before, during, and after the interventions. We compared serum cytokine levels and serum and 24-h urine cortisol levels in the humor and control groups and performed regression analyses of these outcomes, adjusting for demographics and the current use of prednisone. RESULTS: There were no significant differences between the control and humor groups in demographics or clinical variables. Baseline serum levels of IL-6, IL 10, tumor necrosis factor-alpha, and B-cell activating factor were also similar in both groups. There was no evidence of a humor effect in terms of decreasing cytokine levels, although there was some suggestion of lowered cortisol secretion in the humor group based the 24-h urinary cortisol levels in a subgroup. CONCLUSION: In contrast to what has been published for RA, we saw no clear effects of humor in altering cytokine levels in SLE, although interesting trends were seen for lower cortisol levels after humor intervention compared with the control group. PMID- 27708913 TI - Early detection of spondyloarthropathy in patients with psoriasis by using the ultrasonography and magnetic resonance image. AB - OBJECTIVE: To assess the validity of ultrasound (US) in the early detection of arthritis and enthesitis, with assessment of the validity of magnetic resonance imaging (MRI) in the early detection of sacroiliitis and spondylitis in patients with psoriasis and to compare the findings of clinical examination and conventional radiography. MATERIAL AND METHODS: The study included 50 patients with psoriasis and 20 healthy controls. All patients and controls underwent US and power Doppler analyses for the joints of both hands and feet and the entheseal sites. MRI of the lumbosacral spine and sacroiliac joints was performed. RESULTS: Abnormal US findings of arthritis were present in 18% patients, whereas only 6% patients had X-ray abnormalities, the enthesopathy represent 74%, at a higher percentage than clinical and radiological assessment (46, 26% respectively). MRI and radiological study demonstrated evidence of inflammation in the spine in 44% and 16% patients, respectively, and evidence of sacroiliitis in 10% and 6% patients, respectively. CONCLUSION: Use of newer imaging modalities allows early diagnosis and early initiation of therapy. PMID- 27708914 TI - Clinical utility of bone scintigraphy in patients with limb pain of suspected musculoskeletal origin. AB - OBJECTIVE: To determine the clinical utility of bone scintigraphy in patients with limb pain of suspected musculoskeletal origin. MATERIAL AND METHODS: All patients aged >=18 years who were referred for diagnosis and management of limb pain were diagnosed on the basis of history, physical examination, and investigations excluding bone scintigraphy. After the presumptive diagnosis was made (the pre-test diagnosis), all subjects underwent bone scintigraphy, or if they had a previous bone scintigram for their pain condition, the results of that scintigram were reviewed. Then, the pre-test diagnosis was reviewed in light of the bone scintigraphy findings and repeat clinical assessment as needed. The post test diagnosis was considered either as unchanged diagnosis or changed diagnosis for the region or regions of interest. RESULTS: There were 118 females (54.8%) and 97 males (45.2%). The mean age of the entire group was 36+/-8.1 years (range: 18-87 years). The mean duration of the symptoms was 17.4+/-11.2 months (range: 1 264 months). Of the 215 subjects, 212 had a bone scintigram. Of these 212 subjects, none had a changed diagnosis. CONCLUSION: In the evaluation of limb pain of suspected musculoskeletal origin, scintigraphy is unlikely to alter the pre-test diagnosis or affect treatment decisions after history, physical examination, and non-scintigraphic investigations. The clinical utility of scinitigraphy in this setting is low. PMID- 27708915 TI - Neutrophil-lymphocyte ratio in children with familial Mediterranean fever: Original article. AB - OBJECTIVE: The aim of present study was (a) to evaluate the relationship between the neutrophil/lymphocyte (N/L) ratio and mutation types of familial Mediterranean fever (FMF) in children and (b) to evaluate the relationship between the N/L ratio and age. MATERIAL AND METHODS: Three hundred forty-three children with familial Mediterranean fever in the attack-free period and 283 healthy control children were included in the study. Patients were divided into subgroups according to mutation types. Neutrophil and lymphocyte counts were retrieved from medical records of patients and the N/L ratio was calculated from these parameters. RESULTS: The N/L ratio of patients was found to be significantly higher than that of controls (p<0.001). Among 343 patients, homozygous, heterozygous, and compound mutations were observed in 39, 253, and 51 patients, respectively. The differences in the N/L ratio among patients with homozygous, heterozygous, and compound mutations were not statistically significant. The most common mutations were M694V (n=126), E148Q (n=70), M680I, (n=33), and V726A (n=28). Significant differences were not observed among these mutations in terms of the N/L ratio (p>0.05). In all subjects, there was a weak but significant relationship between age and the N/L ratio (r: 0.215, p<0.001). CONCLUSION: The N/L ratio, which can be determined by simple methods in routine blood tests, may be used for the follow-up monitoring of chronic inflammation in patients. In addition, the N/L ratio may give an idea to clinicians regarding the early initiation of treatment in patients with typical clinical findings of FMF. PMID- 27708917 TI - Tuberculous bursitis of the greater trochanter mimicking ankylosing spondylitis. AB - Tuberculous trochanteric bursitis (TTB) is a rare condition that accounts for 1% of musculoskeletal tuberculosis cases. Extrapulmonary TB is usually diagnosed late because of reduced diagnostic suspicion, particularly in the absence of signs of systemic infection. Herein, we report a case of right hip pain that was misdiagnosed as ankylosing spondylitis. The patient had a history of inflammatory back pain with morning stiffness. However, HLA-B27 was negative. Sacroiliac magnetic resonance imaging (MRI) revealed a giant multiloculated collection (27*16*10 cm). Percutaneous drainage was performed and Mycobacterium tuberculosis was observed in fluid culture. The patient was treated by drainage along with antituberculosis therapy. After 1 year of antituberculosis therapy, control MRI revealed total resolution of the large fluid collection. It is important to emphasize that fever or general symptoms are absent in patients with TTB, as observed in the present case. In endemic countries, TTB should be kept in mind in the differential diagnosis of a patient presenting with chronic hip pain without fever, weight loss, and constitutional symptoms. PMID- 27708918 TI - An unusual cause of medial foot pain: The cornuate navicular. AB - The accessory navicular bone (ANB) is a secondary ossification center of the navicular bone and is rarely observed. Three distinct types of accessory navicular bones have been described. The type III, known as the cornuate navicular, is a rare morphological entity of the accessory navicular bone. We report the case of a patient, 48 years old, who presented with chronic swelling and pain in her left foot. Radiological examination permitted the diagnosis and showed a conflict between the tibial posterior tendon and the cornuate navicular, responsible for the symptoms. Surgical treatment led to symptoms relief. PMID- 27708916 TI - Recent advances in Takayasu's arteritis. AB - Takayasu's arteritis (TAK) is a rare, chronic large-vessel vasculitis (LVV) that predominantly affects the aorta, its major branches, and the pulmonary arteries. Recent advances in the diagnosis, clinical course, disease assessment with biomarkers/imaging and new clinical tools, patient-reported outcomes, and new treatment options of TAK are discussed in this review. Conventional angiography, the gold standard method for initial diagnosis, appears to have been replaced with new imaging modalities such as magnetic resonance angiography (MRA) and 18F fluorodeoxyglucose positron emission tomography (FDG-PET) in recent years. MRA and FDG-PET are also promising for the assessment of disease activity. New tools for disease assessment such as Indian Takayasu's Arteritis Score 2010 (ITAS2010) and color Doppler ultrasound (CDUS) aim to better characterize and quantify disease activity; however, different imaging modalities in routine follow-up are not incorporated sufficiently in these approaches. Prognosis is possibly getting better, with lower mortality in recent years; however, it is difficult to assess the widely different vascular intervention rates among the clinical series. Leflunomide, tumor necrosis factor (TNF)-alpha antagonists, and tocilizumab are new options for patients resistant to conventional therapies. There is a clear need to develop a validated set of outcome measures for use in clinical trials of TAK. The Outcome Measures in Rheumatology (OMERACT) Vasculitis Working Group has taken on this task, finished a Delphi exercise with experts, and aims to develop a core set of outcomes for LVV in accordance with OMERACT Filter 2.0. PMID- 27708919 TI - Successful treatment of tumor necrosis factor receptor-associated periodic syndrome (TRAPS) with tocilizumab: A case report. AB - Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is an autosomal dominant autoinflammatory disease linked to chromosome 12p13 and, more specifically, with mutations within the tumor necrosis factor receptor superfamily, member 1A gene (TNFRSF1A gene). It is characterized by the presence of fever, abdominal pain, myalgia, arthralgia or arthritis, and skin rash. In this report, we describe the case of a patient with tumor necrosis factor receptor-associated periodic syndrome (TRAPS) treated successfully with the anti interleukin-6 (anti-IL-6) receptor monoclonal antibody tocilizumab, while treatment with anti-TNF alpha etanercept and infliximab had both failed. PMID- 27708920 TI - Spinning-induced rhabdomyolysis: A case report and review of literature. AB - Rhabdomyolysis is a condition of skeletal muscle breakdown in which muscle injury causes a release of myoglobin and the muscle enzymes creatine phosphokinase (CPK), lactate dehydrogenase (LDH), and transaminases. Exertional rhabdomyolysis, which is precipitated by exercise or exertion, ranges from mild muscle injury with negligible symptoms or systemic effects to fulminant cases. Herein, we report a 26-year-old female patient who was admitted to our Physical Medicine and Rehabilitation outpatient clinics with severe bilateral thigh pain persisting for 5 days after participating in a spinning class and diagnosed with exertional rhabdomyolysis. Timely diagnosis and treatment prevented the potentially life threatening consequences. We assume that it is essential to raise the awareness of this phenomenon not only by physicians but also by the community, since regular exercise and being physically active are increasingly encouraged in modern life. PMID- 27708921 TI - Methorexate therapy in a patient with rheumatoid arthritis complicated by idiopathic thrombocytopenic purpura. AB - The association of rheumatoid arthritis (RA) and immune thrombocytopenic purpura (ITP) has been reported rarely. Methotrexate, which is used for RA treatment, causes thrombocytopenia. Therefore, in medical practice, physicians avoid using methotrexate for RA in patients who have both RA and ITP. Here, we report an RA case that also had ITP, which did not decrease in platelet count after methotrexate therapy. A 50-year-old woman was diagnosed with diabetes mellitus in 1990, RA in 1995, and ITP in 2000. She had received hydroxychloroquine for more than 5 years. She was treated with prednisolone 16 mg/daily between 2006 and 2007, but she discontinued this therapy because of weight gain. Laboratory findings were not remarkable, except for thrombocytopenia. We started methotrexate therapy 10 mg per week for treatment of RA, and hydroxychloroquine therapy was stopped due to nonresponse. The methotrexate dose was increased up to 15 mg/week. Her complete blood cell count was monitored frequently. We did not observe any decrease in platelet count, while active arthritis symptoms of the patient were relieved. This case shows that methotrexate may be used in patients diagnosed with RA that is associated with ITP under strict monitoring.

AB - OBJECTIVE: To determine the correlation among severity of hip osteoarthritis, disability, and Perceived injustice. MATERIAL AND METHODS: A cohort of 46 participants with unilateral hip osteoarthritis underwent hip range of motion measurements and completed the Injustice Experience Questionnaire (IEQ), the Hip Disability and Osteoarthritis Outcome Score (HOOS), and a Croft radiological grading of osteoarthritis severity. RESULTS: The mean age of the cohort was 62.7+/-10.4 years, and the cohort included 27 females. The mean duration of symptoms was 46.9+/-20.6 months. The means of each of the five subscales of the HOOS were as follows: Pain, 62.3+/-9.4; Other Symptoms, 56.7+/-9.6; Function in Activities of Daily Living (ADL), 58.2+/-6.7; Function in Sport and Recreation (Sport/Rec), 58.1+/-6.7; and Hip-Related Quality of Life (QOL) 59.9+/-7.5. The combined mean hip range of motion (abduction, adduction, flexion, extension, external rotation, internal rotation) was 215.9+/-10.9 degrees. The mean IEQ score (Perceived injustice) was 12.0+/-1.7. Of the available factors, only QOL, hip range of motion, and the Croft radiological osteoarthritis grade predicted Perceived injustice scores, with an R-squared of 0.81 in multiple regression analysis. CONCLUSION: In this cohort of patients with unilateral osteoarthritis, more severe disease (as measured by restricted range of motion and radiological severity) was highly correlated with higher levels of Perceived injustice. Perceived injustice may thus reflect an appropriate response to the severity of the disease and is thus more likely a result of the disease process and subsequent disability rather than a cause of disability. PMID- 27708926 TI - Prevalence and factors associated with self-medication in rheumatology in Sub Saharan Africa. AB - OBJECTIVE: We sought to determine the prevalence of and factors associated with self-medication in patients with rheumatic diseases. MATERIAL AND METHODS: An analytical cross-sectional study was conducted from February to July 2013 in the rheumatology department. We included all patients who consulted for a rheumatic disease during the study period and who gave their consent. RESULTS: In total, 203 patients were included; of these, 146 patients (71.92%) had practiced self medication. Furthermore, 99 patients (48.8%) had practiced self-medication for rheumatologic problems. The mean age of the patients was 45.5 years (range: 18-75 years). State officials accounted for 44.4% of patients. Eighty-one patients were schooled. Low back pain (29.29%) was the main reason for consultation, followed by polyarthralgia (12.12%). Using a visual analogue scale, the level of pain for which patients had used self-medication was rated as >70 out of 100 in 57.6% of patients. Fifty-five patients often self-medicated and 28 patients rarely. Drugs were bought from the pharmacy in 97% of cases. The main channel of self medication was word of mouth (43.4%). The drugs used were mainly anti inflammatory drugs (diclofenac: 54.54% and ibuprofen: 57.57%). Ten patients were unaware of the risks of self-medication. In multivariate analysis, sex, education level, and occupation were statistically associated with self-medication. CONCLUSION: Self-medication for a specific rheumatologic symptom appears less common than self-medication in general. The procedures for responsible self medication should be defined in Burkina Faso in order to minimize the risks. PMID- 27708927 TI - Sarcopenia in women with rheumatoid arthritis. AB - OBJECTIVE: To assess sarcopenia status in women with rheumatoid arthritis (RA). MATERIAL AND METHODS: Thirty female patients with RA and 30 female controls without RA were enrolled in this study. Sarcopenia status in patients with RA was evaluated by assessing body composition using dual X-ray absorptiometry (DXA). C reactive protein (CRP) levels and erythrocyte sedimentation rate (ESR) were measured, and body mass index (BMI) and Disease Activity Score (DAS28) were calculated. Because sarcopenia differs between men and women, the study groups comprised only females. RESULTS: It was found that skeletal muscle index (SMI) was lower in patients with RA (5.83+/-0.807) than in controls (7.30+/-1.640). Sarcopenia (in females with an SMI of <=5.75 kg/m2) was more common in the RA group and the difference was statistically significant (p=0.004). Sarcopenia was more common in patients with RA who were normal or overweight than in those who were obese according to their BMI. There was no relationship between sarcopenia and DAS28 in the RA group (p=0.530), whereas CRP levels were significantly higher in patients with sarcopenia (p=0.230). No relationship was found between drug use and sarcopenia in the RA group. CONCLUSION: It was found that SMI was decreased and sarcopenia risk was elevated in patients with RA and the risk was higher in non-obese patients.

AB - OBJECTIVE: Rheumatoid factor (RF) positivity that may occur in a number of patients with hepatitis B (HBV) infection poses challenges in terms of differential diagnosis with rheumatoid arthritis (RA). On the other hand, antibodies to cyclic citrullinated peptide (anti-CCP) may prove to be an important marker for differential diagnosis of the two conditions. This study aimed to assess anti-CCP and RF positivity among patients with hepatitis B and rheumatoid arthritis. MATERIAL AND METHODS: Anti-CCP and RF seropositivity was assessed in 61 patients with HBV infection (32 patients with chronic hepatitis, 29 patients with inactive HBV carrier status) and 40 patients with RA as the control group. RESULTS: RF positivity was found in 18.7% and 34.4% of the patients with chronic hepatitis B and inactive HBV carrier status, respectively. On the other hand, only one patient with chronic HBV had low positive anti-CCP. RF was positive in 24 (60%) and anti-CCP was positive in 26 (65%) patients among the 40 patients with RA. CONCLUSION: Anti-CCP may be helpful in the differential diagnosis between RA and chronic HBV infection or inactive HBV carrier status. PMID- 27708929 TI - Muscular hypertonicity: a suspected contributor to rheumatological manifestations observed in ambulatory practice. AB - OBJECTIVE: The objective of this retrospective study of non-inflammatory rheumatic disease patients was to investigate if the individuals clinically identified with muscular hypertonicity (MHT) had increased clinical manifestations compared with those of age- and gender-matched patients with the same disorders. MATERIAL AND METHODS: The MHT status was clinically identified in the rheumatologist's myofascial protocol examination as relatively increased passive resistance of relaxed muscle on a slow gentle stretch. Clinical and laboratory data were abstracted on a pre-coded form, including symptom and physical examination features, serum assays, and medications. RESULTS: The 19 MHT cases complained of greater subjective stiffness (p=0.010) and tiredness (p=0.018) at initial encounters and increased aching pain (p=0.049) and were prescribed more (p=0.003) mild narcotic analgesics than the 19 comparison patients. The cases had higher (p=0.027) serum creatine kinase levels, and patients with diffuse MHT had greater frequency of heavy (30+pack-years) cigarette smoking (p=0.002) than comparison subjects. Narcotic usage was also greater in cases with diffuse involvement. CONCLUSION: Non-inflammatory rheumatic disease patients with MHT had an overall similar profile as that of comparison patients but had greater musculoskeletal complaints, and those with diffuse involvement had greater narcotic usage. Further research, including quantitative measurements of muscle stiffness, are required to determine whether MHT is a documented entity associated with increased rheumatological manifestations. PMID- 27708930 TI - Erythema elevatum diutinum coexisting with ankylosing spondylitis. AB - A 43-year-old woman presented to our hospital with the complaint of a reddish purple rash on the extensor sides of her forearms. She had been diagnosed with ankylosing spondylitis 7 years ago. On physical examination, reddish-purple nodules were detected on the pretibial areas of both legs and extensor sides of both hands and forearms. Neutrophil, eosinophil, lymphocyte, and mixed-type leukocyte infiltration and erythrocyte extravasation were observed in skin biopsy. Erythema elevatum diutinum (EED) was diagnosed. For treatment, sulphasalazine, colchicine, and diclofenac were started. After 3 months of treatment, the lesions were healed. To the best of our knowledge, this is the first report of EED coexisting with ankylosing spondylitis. PMID- 27708931 TI - A severe case of systemic lupus erythematosus with increased pressure communicating hydrocephalus. AB - Normal/increased pressure hydrocephaly is an unusual manifestation of systemic lupus erythematosus (SLE), and the pathogenesis is still unclear. We report the case of an 18-year-old white female with severe refractory renal and pulmonary involvement who developed stupor during intensive immunosuppressive treatment. Enlarged ventricles on imaging and increased intracranial pressure with the exclusion of infectious and hemorrhagic/thrombotic processes suggested increased pressure communicating hydrocephalus associated with SLE. Few case reports are reviewed, and potential pathophysiologic mechanisms are discussed. PMID- 27708932 TI - Successful treatment of Acrodermatitis continua of Hallopeau associated with psoriatic arthritis with adalimumab. AB - Acrodermatitis continua of Hallopeau (ACH) is a rare form of pustular psoriasis, mainly affecting distal phalanges of hands and feet. Many therapeutic options exist; however, it tends to be resistant to treatment. We report a 26-year-old man presented with a very severe psoriatic arthritis associated with ACH. Although this patient was resistant to a first line treatment (glucocorticoids and methotrexate), a rapid and dramatic improvement was observed after adalimumab was introduced. The effectiveness and tolerance of the treatment were maintained during the 12-month period of follow-up. This is the first report of the efficacy of adalimumab on ACH in a patient presented with psoriatic arthropathy. PMID- 27708933 TI - Subscapular bursitis as a rare manifestation of dermatomyositis: a case report. AB - Dermatomyositis (DM) is characterized by proximal muscle weakness and characteristic skin rash. Pain is a less common feature and usually indicates inflammation of extramuscular structures such as fascia. Here we report a rare case of subscapular bursitis in a 48-year-old woman with DM. She initially presented with severe, sharp, stabbing pain in her right shoulder that worsened with shoulder movement. Magnetic resonance imaging (MRI) revealed inflammation in the right subscapular bursae. A few months later, the patient developed periungual erythema, Gottron's papules, and shawl sign with muscle pain in her thighs. DM was diagnosed based on the presence of interface dermatitis on skin biopsy and diffuse muscle inflammation on MRI. Bursitis and myalgia responded incompletely to nonsteroidal anti-inflammatory drugs but promptly to corticosteroids. Here we report a case of subscapular bursitis as a rare manifestation of DM. Pain in patients with DM may warrant physicians to evaluate for the presence of additional inflammatory processes in the perimuscular structures. PMID- 27708934 TI - High-dose intravenous immunoglobulin therapy for rapidly progressive interstitial pneumonitis accompanied by anti-melanoma differentiation-associated gene 5 antibody-positive amyopathic dermatomyositis. AB - Anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive amyopathic dermatomyositis (ADM) associated with rapidly progressive interstitial pneumonitis (RPIP) frequently has a poor prognosis and optimal treatment is not well defined. Here, we report a 62-year-old Japanese man with anti-MDA5 antibody positive ADM associated with RPIP presented with progressive shortness of breath, Heliotrope rash, Gottron's papules, arthralgia, and fatigue but no sign of muscle weakness. Laboratory investigation revealed serum levels of the following biomarkers: ferritin, 1393 ng/mL; Krebs von der Lungen-6, 1880 U/mL; and creatine kinase, 85 U/L. Computed tomography (CT) images showed diffuse ground-glass opacity in both lung fields. Because anti-MDA5 was positive, we made a diagnosis of ADM associated with RPIP and initiated treatment. Following five courses of combination therapy with prednisolone, cyclosporine A, and intravenous cyclophosphamide (IVCY), IVCY treatment was switched to high-dose intravenous immunoglobulin therapy (IVIg) because of the reactivation of interstitial pneumonia with an increased serum ferritin level. Additional treatment with IVIg improved RPIP, with normalization of anti-ADM antibody levels. Therefore, IVIg mayt be a new candidate treatment for anti-MDA5 antibody-positive ADM associated with RPIP. PMID- 27708935 TI - Ileum and colon perforations in a young patient with Behcet's disease. PMID- 27708936 TI - Rheumatoid arthritis in a patient with bilateral congenital aplasia of the thumbs. PMID- 27708937 TI - Ischemia-hyperpnea test is useful to detect patients with fibromyalgia syndrome. AB - OBJECTIVE: To demonstrate the prevalence of neuromuscular hyperexcitability in Fibromyalgia Syndrome (FMS) by electromyography ischaemia-hyperpnea test (IHT) and its correlation with clinical and clinimetric parameters. MATERIAL AND METHODS: One hundred and forty-five FMS patients underwent IHT to evaluate neuromuscular hyperexcitability and were evaluated for pain (numeric Rating Scale and Regional Pain Scale), tenderness (tender points), disability [Fibromyalgia Impact Questionnaire (FIQ), Health Assessment Questionnaire (HAQ)], quality of life (QOL) [Short Form 36 (SF36)], mood [Hospital Anxiety and Depression Scale (HADS)], sleep [numeric rating scale (NRS)], and fatigue [Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT)]. RESULTS: Of the 145 patients, 95 were tested positive by IHT, and 33 and 17 patients were negative and borderline, respectively. By comparing the three groups, IHT positive patients had lower age and lower SF36 vitality (V), social activities (SA), and mental summary index (MSI) than negative patients (p<0.05). By comparing positive versus negative patients and by comparing positive and borderline patients versus negative patients, it was found that FACIT was higher, whereas age, SF36 V, SA, mental health (MH), and MSI were lower (p<0.05). CONCLUSION: FMS patients present a high prevalence of neuromuscular hyperexcitability, as assessed by IHT. IHT positive patients have poor QOL and higher fatigue than IHT negative patients. Thus, IHT positivity could identify FMS patients with a more severe disease. PMID- 27708938 TI - Overview of the publications of rheumatologists after the millennium. AB - OBJECTIVE: Scientific progress can be directly measured by the growth of the scientific archive. To our knowledge, there has never been a systematic evaluation of the number and properties of the publications of rheumatologists. In this paper, we aimed to evaluate the properties of these papers. MATERIAL AND METHODS: All papers that were published between 2000 and 2011 by at least one rheumatologist author and that were indexed in Science Citation Index Expanded were evaluated. For this purpose, we used the ISI web of knowledge web of science software. RESULTS: Original articles were the most common document type. Most of the papers were published in rheumatology journals. From the point of the number of published papers, the top 3 countries were United States, England, and Germany; the top 3 journals were Annals of Rheumatic Diseases, Rheumatology, and Arthritis and Rheumatism, and the top 3 institutes are Harvard University, Leiden University, and The Imperial College of Science, Technology. Moreover, the publications of rheumatologists increased annually between 2000 and 2011. CONCLUSION: This paper is an overview of the publications of rheumatologists between 2000 and 2011. The results indicate an increasing trend of scientific productivity for rheumatologists. The outcomes about countries, institutions, and journals are in concordance with the general medical publication trends. More than half of the publications written by rheumatologist were published by rheumatology journals. We consider only quantitative data about publications; new research is required to qualitatively evaluate the data. PMID- 27708939 TI - Genistein protects dermal fibrosis in bleomycin-induced experimental scleroderma. AB - OBJECTIVE: Genistein, a phytoestrogen, has anti-oxidant, anti-inflammatory, and anti-angiogenic properties. The aim of the present study is to evaluate the protective effect of genistein in bleomycin (BLM)-induced dermal fibrosis. MATERIAL AND METHODS: This study involved four groups of Balb/c mice (n=10 per group). Mice in three groups were administered BLM [100 MUg/day in 100 MUL phosphate-buffered saline (PBS)] subcutaneously for 4 weeks; the remaining (control) group received only 100 MUL/day of PBS subcutaneously. PBS or BLM was injected into the shaved upper back. Two of the BLM-treated groups also received genistein (1 or 3 mg/kg/day, subcutaneously, to the dorsal front of neck). At the end of the fourth week, all mice were sacrificed and blood and tissue samples were obtained. RESULTS: The BLM applications increased the dermal thicknesses, tissue hydroxyproline contents, alpha-smooth muscle actin-positive cell counts, and led to histopathologically prominent dermal fibrosis. The genistein treatments decreased the tissue hydroxyproline contents and dermal thicknesses, in the BLM-injected mice. CONCLUSION: Genistein has antifibrotic potential in BLM induced dermal fibrosis model. However, its therapeutic potentials on human scleroderma require evaluation in future studies. PMID- 27708940 TI - Frequency of dense fine speckled pattern in immunofluorescence screening test. AB - OBJECTIVE: The presence of antinuclear antibodies (ANA), directed against intracellular antigens, is a distinctive feature of systemic autoimmune rheumatic diseases (SARDs). The standard test for antinuclear antibody screening is the indirect immunofluorescence (IIF). Anti-dense fine speckled 70 (anti-DFS70) antibodies were initially identified as an ANA IIF pattern from a patient with interstitial cystitis, but they were later associated with various other conditions. The objective of the study was to determine the frequency of anti DFS70 antibodies in a cohort of patients undergoing routine ANA testing. MATERIAL AND METHODS: From January 2011 to January 2012, a total of 5800 serum samples were screened for ANA by IIF (Euroimmune AG, Lubeck, Germany). DFS pattern was searched. RESULTS: ANA were present in 1302 (22.4%) of all patients. There were 16 (1.2%) anti-DFS70 antibody-positive patients. The number of females and males who have anti-DFS70 antibody was eleven and five, respectively. All of the samples presented a titer of >=1/320. There was one patient with SARD from the rheumatology department. Another 15 patients were from gastroenterology, endocrinology, and general internal medicine. CONCLUSION: Although a distinctive clinical association has not been reported, anti-DFS70 have been proposed as a significant biomarker for the exclusion of SARD. The present study is a preliminary study. There is a need for a reliable assay to ensure reactivity to DFS70 and screening large populations. PMID- 27708941 TI - Short-term effect of the combination of hyaluronic acid, chondroitin sulfate, and keratin matrix on early symptomatic knee osteoarthritis. AB - OBJECTIVE: In the last years, symptomatic slow-acting drugs for osteoarthritis (SYSADOA) have been vastly studied and have generated considerable interest among clinicians. SYSADOA are generally used as a ground therapy with the main rationale to reduce the consumption of nonsteroidal anti-inflammatory drugs (NSAIDs) and thus limit the related adverse events. MATERIAL AND METHODS: In this study, we evaluated the short-term effect of an oral combination of hyaluronic acid, chondroitin sulfate, and keratin matrix on early symptomatic knee osteoarthritis. Forty patients were treated for 1 month and were allowed to assume analgesics or NSAIDs if necessary. RESULTS: At 2 months, the mean reduction of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score was 36% (p<0.001), and the mean reduction of the WOMAC pains score was 40% (p<0.001). Only two patients reported a sporadic need to assume analgesics; no patient reported any side effect during the study period. CONCLUSION: This data demonstrates that the oral combination of hyaluronic acid, chondroitin sulfate, and keratin matrix is safe, well tolerated, and shows a rapid action reducing pain and improving joint function and stiffness in early symptomatic knee osteoarthritis. PMID- 27708943 TI - Propylthiouracil-induced alveolar hemorrhage. AB - Thionamide induced vasculitis is a multisystem disease. The patients may present with different clinical signs and findings due to organ involvement. These patients are almost always perinuclear antineutrophil cytoplasmic antibody (pANCA) or antimyeloperoxidase (MPO) positive. Clinical findings are not seen in all of the patients who are ANCA positive while using thionamide. Although symptoms usually resolve with drug discontinuation, some patients, however, require high-dose steroids, immunosuppressants, or plasmapheresis. We present here a case of alveolar hemorrhage induced by propilthiouracil (PTU) during treatment with PTU for Graves' disease; patients completely recovered with corticosteroid, cyclophosphamide, and plasmapheresis. PMID- 27708942 TI - Fatigue in rheumatic diseases. AB - Fatigue is a common and important problem in many diseases including rheumatologic illnesses, and it has a negative impact on health-related quality of life. Fatigue is described as having an impact on multiple aspects of a patient's life. There is a need for knowledge about causes of and treatments for fatigue to ensure that patient outcomes are improved. There are several effective treatment strategies available for fatigue including pharmacological and non pharmacological therapies. We aim to provide an overview of fatigue in rheumatologic disorders and some recommendations on its optimal management. PMID- 27708944 TI - Pulmonary tuberculosis presenting with oral aphthae. AB - Tuberculosis is caused by the Mycobacterium tuberculosis bacterium. Tuberculosis primarily affects the lungs. Patients mainly complain of cough, sputum, night sweating, weight loss, and fever. However, there may be cases of atypical presentations. Although aphthous mouth ulcers are mostly present in the oral cavity in primary tuberculosis patients, our literature search showed only one case report of pulmonary tuberculosis with oral aphthae. Here we report a case of a patient with pulmonary tuberculosis admitted to the hospital with the complaint of oral aphthae. PMID- 27708945 TI - Refractory anemia in systemic sclerosis: myelodisplastic syndrome. AB - Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterized by small vessel vasculopathy, autoantibodies, and skin or visceral organ fibrosis (lung, oesophagus, kidney etc.) as a result of extracellular collagen deposition. The cancer risk is higher in many rheumatic diseases, including SSc. Various defined malignancies may develop in 3%-11% of patients with SSc. These solid tumors are generally observed in the lung, oesophagus, or breast. In addition, an increased risk for hematological cancers were reported in literature. Herein, we describe an interesting case of SSc complicated by myelodisplastic syndrome (MDS). Our aim is to draw attention to developing cancers and the rare occurence of MDS in patients with SSc. PMID- 27708947 TI - Magnetic resonance imaging in the diagnosis and follow-up of giant cell arteritis: case report and review of literature. AB - A female patient with giant cell vasculitis of the abdominal aorta and its branches and strongly suspected of having extrapulmonary tuberculosis is presented. The diagnoses were based on the clinical picture, laboratory findings, and magnetic resonance imaging (MRI) findings. MRI is highly useful in cases where echosonography and/or vascular biopsy for histopathological analyses are not possible. A combination of giant cell vasculitis and extrapulmonary tuberculosis is extremely rare, and therefore, choosing the right treatment presents a considerable challenge. MRI performed after 6-month antituberculous therapy and 1-year glucocorticoid plus methotrexate therapy showed normal wall of the aorta and its branches, which was consistent with clinical and laboratory remission. Patients with large vessel vasculitis require regular follow-up by MRI. PMID- 27708946 TI - Familial aggregation of Crohn's disease and necrotizing sarcoid-like granulomatous disease. AB - Granulomatous inflammatory diseases are disorders of an undetermined etiology, affecting different organs and having a diverse clinical course. Familial aggregation of these disorders is being reported increasingly, most commonly familial Crohn's disease. We described the coexistence of Crohn's disease and necrotizing sarcoid-like granulomatous disease in two siblings from a first degree consanguineous Saudi family. The first child presented with recurrent abdominal pain associated with bloody stool and arthritis, whereas the second child presented with fever of unknown origin and lymphadenopathy as well as hepatomegaly without gastrointestinal tract disease. They are phenotypically different; however, they share a novel risk locus and allele. This report supports the heritability and familial aggregation of granulomatous inflammatory diseases and suggests that one causal mutation underlies both Crohn's disease and necrotizing sarcoid-like granulomatous disease. PMID- 27708948 TI - Churg-Strauss syndrome occurring during omalizumab treatment. PMID- 27708949 TI - Differential diagnosis of elevated erythrocyte sedimentation rate and C-reactive protein levels: a rheumatology perspective. AB - OBJECTIVE: In the case of high erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) levels, the diagnosis of the underlying disease can be challenging especially in serologically unrevealing patients who have nonspecific clinical findings. We aimed to investigate the final distribution of definitive diagnoses in patients who initially presented with nonspecific clinical findings and sustained elevations in serum ESR/CRP levels. MATERIAL AND METHODS: The medical records of patients hospitalized in a rheumatology clinic between January 2010 and January 2011 were retrospectively analyzed. The patients were classified into two main groups: those with previously diagnosed underlying rheumatic disease (RD) and those without. The groups were analyzed for the final distribution of definitive diagnoses. RESULTS: Out of 112 patients in the general study population, 47 had a previous RD and 65 had no previous history of RD. In these 65 patients, the most common etiology of nonspecific elevations in ESR/CRP levels was new onset RD (52.3%). Polymyalgia rheumatica (PMR) was the most common new onset RD (38% of all new onset RD) followed by seronegative rheumatoid arthritis. The incidences of infections and malignancies were 24.6% and 9.2%, respectively. CRP levels were significantly higher in infections when compared with new onset RD or malignancies (p<0.05). In patients with previous RD, the flare of the underlying disease was the most common etiology of nonspecific elevations in ESR/CRP levels (n=39, 83%, 20 female/19 male). CONCLUSION: Extraordinarily high levels of serum CRP in a patient with nonspecific clinical findings should raise suspicion for non-rheumatic diagnoses, such as infection and malignancy, even in the presence of a previously diagnosed RD. Advanced radiological investigation is justified in these cases to rule out malignancy. PMID- 27708950 TI - Differential assay reactivity of immunglobulin A anti-beta2 glycoprotein I antibodies: implications for the clinical interpretation of antiphospholipid antibody testing. AB - OBJECTIVE: The routine measurement of IgA anticardiolipin (aCL) and IgA anti beta2 glycoprotein I (anti-beta2 GPI) antibodies remain controversial despite several studies demonstrating an association with thromboembolic disease in patients with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). This controversy may be a contributing factor for the current under use of IgA antiphospholipid antibodies. We aimed to investigate the nature of discrepant IgA anti-beta2 GPI reactivity to help define the diagnostic value of IgA antiphospholipid antibodies. MATERIAL AND METHODS: Four sera selected from SLE/APS patients and positive for antiphospholipid antibodies but having discrepant IgA anti-beta2 GPI reactivity on two commercial assays were studied. IgA antibodies were affinity purified to investigate anti-beta2 GPI reactivity. Column wash through and eluent fractions were tested on both IgA anti-beta2 GPI assays. Results were normalized to total protein. Assay conjugates and standards from the discrepant assays were interchanged. RESULTS: The diseased samples were strongly positive in one assay [144-388 IgA antiphospholipid (APL) units] and negative or weakly positive in another assay (9.9-53 APL units). IgA eluents from IgA anti-beta2 GPI positive samples reacted 10 times stronger on the reactive assay. When normalized to protein content, the eluents showed no cross-reactivity for IgG or IgM anti-beta2 GPI antibodies, confirming IgA isotype specificity. Conjugate interchange confirmed that both assays bound IgA anti-beta2 GPI antibodies, but the anti-IgA conjugate from the reactive assay was 4 times stronger, suggesting that its ability to detect IgA anti-beta2 GPI antibodies was partially dependent on the anti-IgA conjugate and calibration. CONCLUSION: These results confirm not only the presence of IgA anti-beta2 GPI antibodies in the selected patient samples but also highlight an IgA conjugate issue for the unreactive assay, causing an underestimation of IgA anti-beta2 GPI. This finding may assist in the ongoing standardization efforts of APS antibody testing. In addition, conclusions from published clinical studies may need to be revised as some assays may understate IgA significance. PMID- 27708951 TI - Characteristics and outcomes of chronic non-bacterial osteitis in children. AB - OBJECTIVE: To determine patient characteristics, clinical presentation, pattern of involvement, treatment, and outcome of patients with chronic non-bacterial osteitis (CNO). MATERIAL AND METHODS: Consecutive cases of CNO were analyzed at a single center for pediatrics and adolescent medicine from 2006 to 2013 in terms of patient characteristics, clinical presentation, pattern of involvement, treatment, and outcome. RESULTS: We identified 32 children aged 1.5-15 years who were diagnosed with CNO between 2006 and 2013. A maximum of 12 bones per patient were affected in a total of 114 documented locations. The pelvis and clavicle (affecting 34% of patients each) were the most frequently affected bones. The foot skeleton was the most commonly affected region in 60% of patients. Skin manifestations were found in 7 (21%) patient. Increased inflammatory signs at presentation were detected in 18 patients. Pathological findings were found in all 30 children examined using magnetic resonance imaging (MRI), in 10 of 11 children examined using radiography, and in 8 of 10 patients examined using skeletal scintigraphy. Bone biopsy was performed in 9 patients. For initial treatment, non-steroidal anti-inflammatory drugs (NSAIDs) or coxibs were used in 28 (87.5%) patients. Remission or satisfactory follow-up was achieved in all patients. CONCLUSION: Today, CNO is increasingly diagnosed using MRI and rarely through histological examinations. Therapeutic strategies include NSAIDs, which are often highly effective. All patients in the present study showed good clinical outcomes. PMID- 27708952 TI - Rumination modulates stress and other psychological processes in fibromyalgia. AB - OBJECTIVE: Fibromyalgia (FM) is characterized by widespread pain and high levels of sleep disturbance, fatigue, and altered cognition. Psychological stress can modulate these features. In this study, we examined the thinking style of rumination in women with FM to assess the effect of rumination on stress levels and other psychological variables in FM. MATERIAL AND METHODS: Ninety-eight women with FM completed questionnaires to assess levels of rumination, stress, anxiety, depression, optimism, control, and coping. T-tests and bivariate (Pearson) analysis was performed to assess relationships between rumination and other psychological factors. RESULTS: We found that those with higher levels of rumination had increased the use of negative coping techniques (p<0.001), higher anxiety (p<0.001), depression (p<0.001), and poor sleep levels (p<0.05). Higher rumination correlated with lower optimism (p<0.001) and control (Mastery) (p<0.001). High rumination correlated strongest with stress (p<0.001). Rumination predicted 26% of variance for perceived stress. CONCLUSION: Rumination influenced several psychological processes deemed important in FM and was an important contributor to stress in FM. Specific interventions targeting rumination in FM may improve FM symptoms and outcomes. PMID- 27708953 TI - Current antiviral practice and course of Hepatitis B virus infection in inflammatory arthritis: a multicentric observational study (A + HBV study). AB - OBJECTIVE: The reactivation of hepatitis B virus (HBV) infection is a well-known event in hepatitis B surface antigen (HbsAg)-positive patients receiving immunosuppressive therapy. The objective of this study was to assess the antiviral practice and course of HBV infection in inflammatory arthritis. MATERIAL AND METHODS: Nineteen rheumatology centers participated in this retrospective study. HbsAg-positive patients who were taking disease-modifying antirheumatic drugs and who were being tested for HBV viral load at a minimum of two different time points were included. The case report form (CRF) consisted of demographic data, rheumatic diseases, treatment profiles, transaminase levels, viral hepatitis serological markers, and HBV viral load. The reactivation of HBV was defined as the abrupt rise in HBV replication by an increase in serum HBV DNA levels in a patient with a previously inactive HBV infection. RESULTS: In total, the data of 101 (female 50.5%) patients were included (76 patients with inactive HBV carriers and 25 patients with chronic HBV infection). The mean age of patients was 44+/-12 years, and the mean follow-up duration was 31+/-22 months. Of the 101 patients, 70 (69.3%) received antiviral treatment. HBV reactivation was detected in 13 of 76 (17.1%) patients with inactive HBV carriers. HBV reactivation was observed less frequently, not although significantly, in those patients receiving antiviral prophylaxis compared with those not receiving prophylaxis [5/41 (12.2%) vs. 8/33 (24.2%), p=0.17]. Forty-two patients (31 patients had inactive HBV carriers) were using anti-tumor necrosis factor agents. HBV reactivation was detected in 6 of the 31 (19.3%) patients. Twenty-five patients had chronic hepatitis, and five (20%) of them had not received antiviral prophylaxis. HBV viral loads were persistently elevated in 7 (28%) of 25 patients (three patients under and four patients not under antiviral treatment). CONCLUSION: HBV reactivation was observed in approximately 17% of patients under immunosuppressive treatments. HBV reactivation was more frequently observed in those who did not receive antiviral prophylaxis. PMID- 27708954 TI - Relapsing polychondritis. AB - Relapsing polychondritis (RPC) is a unique and rarely observed autoimmune condition regarded as recurrent extensive chondritis of the auricular, nasal, and tracheal cartilages. Moreover, heart, main arteries, skin, and eyes may be involved. Several forms of clinical manifestations may be seen, and the pathogenesis still remains anonymous. A concomitant disease, particularly myelodysplasia or other systemic autoimmune disease can be detected in one-third of the patients with RPC. The treatment of RPC should be considered on personal basis and classified according to disease activity and severity. This study reviews the available data on clinical manifestations, pathogenesis, diagnosis, and therapeutics of the RPC. PMID- 27708955 TI - Dermato-neuro syndrome in a case of scleromyxedema. AB - Scleromyxedema is an uncommon connective tissue disease characterized by mucin deposits, fibrosis, and proliferation of fibroblasts in the dermis. Although it shares similar sclerodermoid features, it is a different clinical entity than scleroderma. A monoclonal gammopathy is almost always present; however, progression to multiple myeloma is rare. It may have many systemic manifestations, of which the most notable being the dermato-neuro syndrome because of its rarity and potential fatal outcome. We present a case of a 50-year old woman with scleromyxedema in whom the dermato-neuro syndrome developed. PMID- 27708956 TI - Therapy resistant idiopathic scleredema: an underlying pathology not always present. AB - Scleredema is a rare connective tissue disorder of unknown pathogenesis. Three types of scleredema have been described, based on its association with postinfection, monoclonal gammopathy and diabetes mellitus. We report herein a case of scleredema which the diagnosis didn't get specified. The patient was followed regularly for 13 years and did not respond to various combinations of immunosuppressants and psoralen plus ultraviolet A therapy. Treatment of scleredema is quite difficult and of limited success. At present, there is no proved treatment for this disease. PMID- 27708957 TI - Sjogren's syndrome after silicone breast implantation. AB - Sjogren's syndrome, an autoimmune disease characterized by lymphocytic infiltration of the lacrimal and salivary glands, leads to dryness of the mouth and eyes. Herein, we present a case of Sjogren's syndrome that developed after silicone breast implantation. A cause-effect relationship between breast implantation and Sjogren's syndrome has not been established. However, the possibility of such an association should be considered when a patient with silicone implants is admitted to the hospital for treatment of Sjogren's syndrome. PMID- 27708958 TI - A missed Behcet's case presenting with spontaneous epidural hematoma. AB - Spinal vascular events related to Behcet's disease are relatively uncommon. Deep vein thrombosis is the most frequent vascular involvement. Anticoagulant therapy is a debated issue in Behcet's disease. In this case report, we present a patient with a delayed diagnosis of Behcet's disease after development of cervical epidural hematoma following anticoagulant therapy due to deep venous thrombosis. Anticoagulant therapy without immunosuppressive therapy leading to uncontrolled systemic inflammation may be the cause of spinal epidural hematoma. On the other hand, epidural vascular involvement as a vasculitic manifestation of Behcet's disease in conjunction with anticoagulant therapy may have predisposed to spontaneous bleeding via increased fragility or microaneurysms in epidural arteries. In this case report, the importance of a multidisciplinary approach to Behcet's disease is emphasized. PMID- 27708959 TI - Rhabdomyolysis probably induced by influenza vaccine and fibrate therapy. PMID- 27708960 TI - Increasing body fat mass reverses bone loss in osteopenia as detected by dual energy X-ray absorptiometry scans. AB - OBJECTIVE: Low body mass index (BMI) is a known risk factor for osteoporosis and is part of the FRAXTM 10-year fracture risk stratification tool for predicting fragility fractures. Little is known regarding the effects of changing body composition on bone mineral density (BMD). However, increasing fat mass (FM) improves BMD in young women with anorexia nervosa. This study aimed to assess whether changes in FM over time affected BMD in the general population. MATERIAL AND METHODS: Data was collected from patients who underwent dual-energy X-ray absorptiometry (DEXA) assessment between 2004 and 2011. Patients were included if they had multiple scans, including FM measurements. Our scanners limited these to scans of the lumbar spine. Linear regression analysis was performed to identify the relationship between changes in FM and BMD. Backwards stepwise linear regression analysis was performed to identify confounding factors, including sex, risk factors, previous fractures, and baseline BMI. RESULTS: In this study, 23,239 patients were included, of which 702 met the inclusion criteria. There were 609 (86%) females and 93 (13%) males with a mean age of 64.5 (SD 11.2) years at first scan. We identified a strong positive correlation between increasing FM and BMD between scans (coefficient 28.4; p<0.01; 95% CI, 26.6-30.1). Previous pelvic and femur fractures and a history of inflammatory diseases were also associated with increasing FM (p<0.05). This relationship was true regardless of patients BMI at their first scan. CONCLUSION: These findings suggest that patients at high risk of fragility fractures should be encouraged to increase their FM as long as they are at a low risk for disease states related to high FM. PMID- 27708961 TI - Postural deformities: potential morbidities to cause balance problems in patients with ankylosing spondylitis? AB - OBJECTIVE: This study aimed to assess the impact of postural deformities caused by ankylosing spondylitis (AS) on balance problems. MATERIAL AND METHODS: This study included 29 patients with AS and 21 healthy controls. For assessing exercise capacity and dynamic balance, timed up and go test, five times sit-to stand test, gait speed, and 6-min walk test were performed. Romberg tests were used to evaluate static balance and proprioception, whereas Dynamic Gait Index (DGI), Functional Gait Assessment (FGA), Berg Balance Scale (BBS), Activity Specific Balance Confidence Scale (ABC), Dizziness Handicap Inventory (DHI), and functional reach test were used to assess dynamic balance and the risk of falling. Using Bath Ankylosing Spondylitis Metrology Index (BASMI) scores, patients with AS were divided into two groups: those with scores 0-4 were assigned to subgroup AS1, and those with scores 5-10 were assigned to subgroup AS2. RESULTS: In the whole group of patients with AS, five times sit-to-stand test, tandem Romberg test with eyes closed, and BBS and ABC scores were significantly worse than the healthy controls (p<0.05). In the AS2 subgroup having more severe and advanced disease, five additional parameters, including timed up and go test, 6-min walk test, functional reach test, FGA, and DHI scores were also significantly worse than the healthy controls (p<0.05). Comparing the two subgroups with each other, only BBS scores were significantly worse in the AS2 subgroup than in the AS1 subgroup. CONCLUSION: Although in clinical practice, poor balance is not a common problem in AS, possibly because of compensatory mechanisms, patients with AS have poorer static and dynamic balance than healthy subjects. Significantly worse BBS scores in the AS2 subgroup than in the AS1 subgroup may suggest the presence of more dynamic balance problems in advanced disease; however, future studies comprising larger samples are necessary to confirm this assumption. PMID- 27708962 TI - Relationship among angiotensin-converting enzyme polymorphism, cardiovascular risk, and osteoporotic fractures. AB - OBJECTIVE: Angiotensin-converting enzyme (ACE) has been related to cardiovascular physiology and bone remodeling. Our aim was to assess the relationship among ACE polymorphisms, cardiovascular risk, and osteoporotic fractures. MATERIAL AND METHODS: We prospectively enrolled 71 patients with hypertension from 2001 to 2014. Sociodemographic and medical data were collected. Comorbidity was evaluated with Charlson index. Densitometric studies on lumbar spine were performed. ACE polymorphism was analyzed by polymerase chain reaction. Data were analyzed using SPSS 15.0 (p value <0.05). RESULTS: Homozygous deletion (DD) genotype was described in 32.4% of patients, homozygous insertion (II) in 19.7%, and heterozygous insertion/deletion (ID) in 47.9%. On stratifying data by ACE polymorphism, we observed that DD carriers demonstrated neither greater cardiovascular risk factors (30.4% vs. 33.3%, p=0.4) and higher comorbidity (34.8% vs. 22.9%, p=0.3) nor higher osteoporotic fracture incidence (17.4% vs. 16.8%, p=0.9). In women, no significant differences were observed between DD homozygous individuals and ID+II subjects. CONCLUSION: It is unclear whether DD genotype is an independent risk factor for cardiovascular disease. In contrast to our expectations, we found no relationship among the DD genotype, cardiovascular risk, and osteoporotic fracture incidence. PMID- 27708963 TI - Impact of standard of care treatments and disease variables on outcomes in systemic lupus erythematosus trials: analysis from the Lupus Foundation of America Collective Data Analysis Initiative. AB - OBJECTIVE: Most clinical trials for systemic lupus erythematosus (SLE) study the efficacy and safety of investigational agents added to variable background immunosuppressants, which has resulted in high response rates in patients treated with placebo plus standard of care (SOC) plus rescue measures. This project compared the impact of different SOC treatments and disease variables on the outcomes of SLE trials. MATERIAL AND METHODS: Data were obtained from 981 patients receiving only SOC treatments in three nephritis and three general SLE trials to compare response and flare rates on the basis of the British Isles Lupus Assessment Group (BILAG) index, a measure common to all trials. RESULTS: For subjects enrolled in general SLE trials (n=173), those receiving mycophenolate mofetil (MMF) had more severe baseline disease, included more patients of African descent, and were administered higher baseline steroid doses compared with those receiving azathioprine (AZA) or methotrexate (MTX). BILAG responses at week 12 were MMF 35%, AZA 49%, MTX 34%, and no immunosuppressant (NIS) 65%. At week 52, MMF response rates increased to 41% despite reducing the steroid doses, but fell in all others (p=0.07, adjusted for steroids). Patients with severe disease activity at baseline (SDAB) who were defined as >=1 BILAG A (severe) organ score had lower response rates to AZA or MTX but higher rates to MMF or NIS. Interim flares were highest with MMF [flares/patient-year (pt-yr)]. For all flares, rates were as follows: AZA 1.24, MMF 1.87, MTX 1.42, and NIS 0.81 and severe flares were as follows: AZA 0.66, MMF 1.29, MTX: 1.20, and NIS 0.55. Interim flares occurred in 71% of MMF-endpoint responders, 54% of AZA, 50% of MTX, and 22% of NIS. Patients with SDAB had more flares than moderate patients in the MMF and MTX groups: MMF: 2.39 vs. 1.03 flares/pt-yr (p=0.01), MTX: 2.33 vs. 0.63 (p=0.0002), severe flares: 1.87 vs. 0.34 for MMF (p=0.0013), 2.13 vs. 0.40 for MTX (p<0.0001). In nephritis trials (n=808), MMF subjects received less steroids than intravenous cyclophosphamide and response rates were similar, but MMF-treated patients had fewer severe flares (p=0.03). CONCLUSION: Compared with MMF, AZA and MTX were associated with lower response rates at week 52. AZA treated subjects had fewer flares and remained more stable in trials while engendering lower placebo plus SOC responses. MMF-treated subjects had frequent responses but more flares, suggesting that flares should be included in endpoint definitions. Given the likelihood of treatment selection bias, these data do not provide conclusions regarding efficacy but may help future trial designs by distinguishing factors definable at entry that are predictive of outcomes. PMID- 27708964 TI - Oxidative stress and related factors in patients with ankylosing spondylitis. AB - OBJECTIVE: Ankylosing spondylitis (AS) is a chronic inflammatory disease of the spine and sacroiliac joints of unknown etiology. Recent studies have reported increased oxidative stress, which is implicated in the pathogenesis of a number of diseases, in AS. The purpose of this study was to investigate oxidative stress and related factors in AS. MATERIAL AND METHODS: Eighty-five patients with AS [36 (16-64) years; 65 male/20 female] and 56 healthy subjects [36 (21-63) years; 39 male/17 female] with no known cardiovascular risk factors were enrolled. Serum total oxidant status (TOS) and total anti-oxidant status (TAS) were studied. The Bath ankylosing spondylitis functional index (BASFI), Bath ankylosing spondylitis disease activity index (BASDAI), and Bath ankylosing spondylitis metrology index (BASMI) were calculated. A logistic regression model was used to identify the independent risk factors for TOS. RESULTS: No differences were observed in terms of demographic characteristics, laboratory findings, or TAS concentrations between the patient and control groups. However, the serum TOS levels were significantly higher in the AS group than in the controls (p=0.003). The comparison of cases of active (BASDAI >=4) and inactive AS revealed significantly higher TOS levels in the active disease group. The TOS and TAS concentrations did not differ between patients treated with biological agents and those treated with conventional agents. Correlation analysis yielded significant correlations between TOS and TAS, BASMI, BASFI, BASDAI, erythrocyte sedimentation rate (ESR), and high-sensitive C-reactive protein (hs-CRP) (p<0.05; r values ranged from 0.291 to 0.452) and a positive correlation between TAS and BASMI (p<0.05; r=0.344). Based on regression analysis, BASDAI, BASMI, and hs-CRP independently predicted the TOS levels [p<0.05, R2: 0.262, and standard error of the estimate (SEE): 10.96]. CONCLUSION: Oxidative stress levels were higher in patients with AS than in healthy subjects. Patients with active disease status had significantly higher oxidative stress than patients with inactive disease status and healthy controls. Treatment status has no effect on TOS, and BASMI, BASDAI, and hs-CRP are independent variables associated with TOS. The TAS levels were found to be associated with only BASMI. PMID- 27708965 TI - Viral hepatitis screening guideline before biological drug use in rheumatic patients. AB - Biological drugs (tumor necrosis factor inhibitors, rituximab, tocilizumab, abatacept, and tofacitinib) are important treatment alternatives in rheumatology, particularly for resistant patients. However, they may cause hepatitis B virus (HBV) and hepatitis C virus (HCV) reactivation; for instance, HBV reactivation may occur in a patient who is an inactive hepatitis B surface antigen (HBsAg) carrier or who has resolved HBV infection. Therefore, the screening of patients before biological treatment and the application of a prophylactic treatment, particularly with respect to latent HBV infections, are recommended when necessary. This guideline covers pre-treatment screening and follow-up recommendations, if required, with respect to viral hepatitides in rheumatology patients who are planned to be given biological drugs. Although this guideline is prepared for biological disease-modifying antirheumatic drugs (DMARDs), it is recommended to be used also for target-oriented DMARDS and medium-high dose corticosteroids (>7.5 mg prednisolone/day equivalent). It should be considered that the reactivation risk is higher when more than one immunosuppressive drug is used. PMID- 27708966 TI - Vaccination recommendations for adult patients with rheumatic diseases. AB - Infectious diseases in any age group can be successfully prevented through immunization. Protection provided through immunization in childhood decreases over the years. Immunization in adulthood is important because of the growing elderly population, chronic diseases, and globalization. Recommendations on this subject are being constantly updated through scientific guidelines. Immunization in adulthood is also important in rheumatology. There is an increased risk not only of infection in rheumatic diseases but also of infections being more severe. Most infections, and their frequently observed complications, are among those diseases that can be prevented through immunization. The type of immunization, immunosuppressive/immunomodulatory therapy received by the patient, disease activity, and presence of chronic diseases affect the immunization process in patients with rheumatic diseases. This review will consider the immunization process followed in rheumatic diseases and also refer to its application. PMID- 27708967 TI - Ethylenediaminetetraacetic acid-dependent pseudothrombocytopenia in a patient with systemic lupus erythematosus and lupus nephritis. AB - Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by several immunological abnormalities. We wish to communicate the case of a patient with SLE and lupus nephritis (LN) who developed pseudothrombocytopenia. Pseudothrombocytopenia can occur in patients with SLE and LN and should be considered when diagnosing patients with thrombocytopenia without bleeding. PMID- 27708968 TI - A case of systemic lupus erythematosus with multiple nodules in the bilateral lungs and vertebrae. AB - We encountered a case of a middle-aged woman with systemic lupus erythematosus. As the patient had progressive peripheral neuropathy including foot drop, we intended to treat her with intensive immunosuppressive therapy as soon as possible. Pretreatment assessment, however, revealed multiple nodular lesions in the lungs and bones, suggesting disseminated tumor metastasis or miliary tuberculosis. To our surprise, gallium and bone scintigraphy as well as cytodiagnosis revealed no sign of malignancy or infection, leading us to suspect the presence of another multisystem disorder. The presence of subependymal nodules and a periungual fibroma strongly suggested tuberous sclerosis (TS). A genetic test revealed a mutation in the TSC1 gene and confirmed the diagnosis. Thus, the multiple nodular lesions were most likely a hyperplasia due to TS. Although the odds of a comorbidity of more than one multisystem disorder are considered to be quite low, it should be kept in mind that when such a situation does exist, the comorbidity may make the presenting symptoms extremely diverse. PMID- 27708969 TI - Rheumatoid arthritis and tabetic arthropathy: physiopathological link or simple association? AB - To the best of our knowledge, the association of rheumatoid arthritis and tabetic arthropathy has never been described before in the literature. We report here a first observation. We report the case of a 50-year-old man, treated for syphilitic arthritis evolving for 4 years, who presented with a table of rheumatoid arthritis. The diagnosis of rheumatoid arthritis was established according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria (ACR/EULAR). The treatment was based on weekly injection of methotrexate and a symptomatic treatment by corticosteroid. The association of rheumatoid arthritis and tabetic arthropathy is rare, to our knowledge this is the first case reported. This case reminds us that a neuropathic arthropathy as tabetic arthropathy, although it is rare, can be associated in a sporadic or exceptional way with other rheumatic disease like rheumatoid arthritis. A physiopathological link between the both diseases remains to be proved. PMID- 27708970 TI - Potential protein targets of the peptidylarginine deiminase 2 and peptidylarginine deiminase 4 enzymes in rheumatoid synovial tissue and its possible meaning. AB - OBJECTIVE: The molecular mechanism of citrullination involves the calcium dependent peptidylarginine deiminase (PAD) family of enzymes. These enzymes induce a stereochemical modification of normal proteins and transform them into autoantigens, which in rheumatoid arthritis trigger a complex cascade of joint inflammatory events followed by chronic synovitis, pannus formation, and finally, cartilage destruction. By hypothesizing that PAD2 and PAD4 enzymes produce autoantigens, we investigated five possible synovial protein targets of PAD enzymes. MATERIAL AND METHODS: We measured PAD2, PAD4, and citrullinated proteins in 10 rheumatoid and 10 osteoarthritis synovial biopsies and then assessed the post-translational modifications of fibrinogen, cytokeratin, tubulin, IgG, and vimentin proteins using a double-fluorescence assay with specific antibodies and an affinity-purified anti-citrullinated peptide (CCP) antibody. The degree of co localization was analyzed, and statistical significance was determined by ANOVA, Fisher's exact test, and regression analysis. RESULTS: The principal results of this study demonstrated that citrullinated proteins, such as fibrinogen, IgG, and other probed proteins, were targets of PAD2 and PAD4 activity in rheumatoid synovial biopsies, whereas osteoarthritis biopsies were negative for this enzyme (p<0.0001). An analysis of citrullination sites using the UniProtKB/Swiss-Prot data bank predicts that the secondary structure of the analyzed proteins displays most of the sites for citrullination; a discussion regarding its possible meaning in terms of pathogenesis is made. CONCLUSION: Our results support the conclusion that the synovial citrullination of proteins is PAD2 and PAD4 dependent. Furthermore, there is a collection of candidate proteins that can be citrullinated. PMID- 27708971 TI - Low vitamin D status in systemic sclerosis and the impact on disease phenotype. AB - OBJECTIVE: Vitamin D has pleiotropic effects including immunomodulatory, cardioprotective, and antifibrotic properties and is thus able to modulate the three main links in scleroderma pathogenesis. The aim of the study was to evaluate the level of vitamin D in patients with systemic sclerosis and to analyze the associations between the concentration of vitamin D and the features of systemic sclerosis. MATERIAL AND METHODS: Fifty-one consecutive patients were evaluated for visceral involvement, immunological profile, activity, severity scores, and quality of life. The vitamin D status was evaluated by measuring the 25hydroxy-hydroxyvitamin D serum levels. RESULTS: The mean vitamin D level was 17.06+/-9.13 ng/dL. Only 9.8% of the patients had optimal vitamin D levels; 66.66% of them had insufficient 25(OH)D levels, while 23.52% had deficient levels. No correlation was found between vitamin D concentration and age, sex, autoantibody profile, extent of skin involvement, or vitamin D supplementation. Vitamin D levels were correlated with the diffusing capacity of the lung for carbon monoxide (p=0.019, r=0.353), diastolic dysfunction (p=0.033, r=-0.318), digital contractures (p=0.036, r=-0.298), and muscle weakness (p=0.015, r=-0.377) and had a trend for negative correlation with pulmonary hypertension (p=0.053, r= 0.29). CONCLUSION: Low levels of vitamin D are very common in systemic sclerosis. Poor vitamin status seems to be related with a more aggressive disease with multivisceral and severe organ involvement, especially pulmonary and cardiac involvement. PMID- 27708972 TI - Surgery for lumbar spinal stenosis in patients with rheumatoid arthritis: A multicenter observational study. AB - OBJECTIVE: To compare clinical outcomes following microdecompression surgery or laminectomy for central lumbar spinal stenosis (LSS) between patients with rheumatoid arthritis (RA) and patients without rheumatic disease. MATERIAL AND METHODS: Data were collected from the Norwegian Registry for Spine Surgery. The primary outcome was change in the Oswestry Disability Index (ODI) score at 1 year. The secondary endpoints were health-related quality of life that was measured using the Euro-Qol-5D (EQ-5D), back pain numerical rating scale (NRS), leg pain NRS, and complications. RESULTS: A total of 1433 patients were included (1396 controls and 37 patients with RA). For all the patients, there was an improvement in ODI score 16.7 points; 95% confidence interval (CI), 15.7, 17.7; p<0.001). There were no differences between controls and patients with RA with respect to the mean changes of ODI scores (-2.5 points; 95% CI, -9.0 to 4.1; p=0.462), EQ-5D (p=0.295), back pain NRS (p=0.194), leg pain NRS (p=0.927), and complications within 3 months of surgery (12.8% vs. 13.5%, p=0.806). At 1 year, 68.6% (n=775) of controls had achieved a minimal clinically important difference (>=8 points ODI score improvement) compared with 65.5% (n=19) of patients with RA (p=0.726). CONCLUSION: Patients with RA experienced similar and large improvements in patient-reported outcomes following surgical decompression for LSS compared with patients without rheumatic disease. There was no increased risk of complications in patients with RA. PMID- 27708973 TI - Relationship between endothelial dysfunction and microalbuminuria in familial Mediterranean fever. AB - OBJECTIVE: The aim of our study is to investigate the relationship between microalbuminuria and flow-mediated dilatation in familial Mediterranean fever (FMF) patients. MATERIAL AND METHODS: In our study, there were two groups consisting of 54 patients who were out of the attack period (43 of whom had no microalbuminuria and 11 of whom had microalbuminuria) and 40 healthy controls (M/F: 12/28). RESULTS: There was no statistically difference between patient and control groups'age (25.06+/-8.07, 22.89+/-6.00 years, respectively). Flow mediated dilatation (FMD) percentages were significantly different between the three groups (p=0.01). It was observed that there was a correlation between microalbuminuria and FMD percentage. CONCLUSION: Endothelial dysfunction and renal damage occurred as a result of low-grade chronic inflammation. Microalbuminuria, which is the indicator of renal damage and endothelial dysfunction, and FMD show that endothelial functions can be used in the following of early detection of renal damage and endothelial functions in FMF patients.

PMID- 27708974 TI - Evaluating disease activity in patients with ankylosing spondylitis and rheumatoid arthritis using 99mtc-glucosamine. AB - OBJECTIVE: To evaluate the clinical utility of a novel radiotracer, 99mTc glucosamine, in assessing disease activity of both rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Material and Methods: Twenty-five patients with RA (nine males and 16 females) and 12 patients with AS (all male) at various stages of disease were recruited for the study. A clinical history and examination was performed, followed by the measurement of hematological, biochemical, and autoimmune serological parameters to assess disease activity. 99mTc-glucosamine was intravenously administered and scans were compared with other imaging modalities, including plain X-ray, magnetic resonance imaging (MRI), and bone scans. RESULTS: In patients with AS, 99mTc-glucosamine scans were more capable of identifying active disease and differentiating between inflammatory and non inflammatory causes. In patients with RA, 99mTc-glucosamine accumulated at all known sites of disease involvement. Uptake was most pronounced in patients with active untreated disease. The relative tracer activity in the involved joints increased with time compared with that in the adjoining soft tissue, liver, and cardiac blood pool. Using Spearman's correlation coefficient, there was a positive correlation among glucosamine scan scores, C-reactive protein (p=0.048), and clinical assessment (p=0.003), which was not noted with bone scans. CONCLUSION: The radiotracer was well tolerated by all patients, with no adverse reactions. 99mTc-glucosamine imaging could detect spinal inflammation in AS. With respect to RA, 99mTc-glucosamine was a viable alternative to 99mTc-labeled methylene diphosphonate nuclear bone scans for imaging inflamed joints and had the added advantage of demonstrating a significant clinical correlation between disease activity and scan findings. PMID- 27708977 TI - Kaposi's sarcoma concurrent with granulomatosis polyangiitis. AB - Kaposi's sarcoma (KS), a malignant vascular tumor, can develop in patients who receive corticosteroids or immunosuppressive therapy. We report a patient with KS and granulomatosis polyangiitis (GPA). To the best of our knowledge, this is the first report regarding the co-occurrence of these two diseases. The physician must be aware of the risk of cancer in patients with rheumatism. PMID- 27708978 TI - Teriparatide for the rapid resolution of delayed healing of atypical fractures associated with long-term bisphosphonate use. AB - Bisphosphonates (BPs) are the most widely used drugs to treat osteoporosis. However, recent reports associated to long-term BPs use with atypical low-impact fractures and prodromal pain. It is estimated that 26% of the cases of atypical fractures associated with the long-term use of BPs show delayed healing or nonunion. Teriparatide [PTH1-34] (TPTD) is an anabolic drug shown to be effective in stimulating bone formation. The aim was to describe the course of a right diaphyseal femoral fracture sustained by a patient on long-term BPs treatment. A 57-year-old postmenopausal Caucasian female presented with delayed healing of a right femoral diaphyseal fracture 10 months after the fracture, despite having received orthopedic treatment. The fracture was preceded by progressive, severe, and bilateral thigh pain. Her medical history included osteopenia that was treated with alendronate over 7 years. On presentation at our clinic, the patient ambulated with the aid of a walking cane. The diagnosis was an atypical right femoral fracture associated with long-term alendronate use. The levels of the following parameters were measured: mineral metabolism laboratory: intact parathormone, 40 ng/mL (reference values (rv): 10-65 ng/mL); 25-hydroxyvitamin D, 40 ng/mL (rv: >30 ng/mL); serum Crosslaps, 318 ng/mL (rv: 80-590 ng/mL); and bone specific alkaline phosphatase, 76UI/L (rv: 31-95UI/L)]. Magnetic resonance imaging of the left femur was performed, which revealed a diaphyseal stress fracture. She was prescribed 20 MUg/day of subcutaneous (s.c.) TPTD (PTH1-34, Forteo; Eli Lilly Co., Indianapolis, IN, United States). A computed tomography scan performed 3 months later showed that the fracture had healed; the patient was able to resume her usual activities. Twenty micrograms per day of s.c. TPD accelerated the healing of the atypical fracture associated with long-term alendronate therapy, allowing a fast recovery of ambulation and quality of life. PMID- 27708979 TI - Hydroxychloroquine-induced agranulocytosis in a patient with long-term rheumatoid arthritis. AB - Agranulocytosis is a rare and little-known side effect of hydroxychloroquine use. This report describes the case of a 71-year-old woman with poorly controlled rheumatoid arthritis who developed agranulocytosis after several months of hydroxychloroquine therapy. She had been on several different disease-modifying antirheumatic drugs, including methotrexate and leflunomide, for her rheumatoid arthritis. Treatment became complicated following a diagnosis of leflunomide induced pulmonary fibrosis that was discovered after an intensive care unit (ICU) admission for severe Pseudomonas pneumonia. All treatment was stopped apart from steroids and hydroxychloroquine. Because of persistent disabling symptoms, rituximab infusions were given, which improved the disease control. A second admission occurred after a routine blood test revealed agranulocytosis. Hydroxychloroquine was stopped, and after 24 h, she was discharged home. Blood counts returned to normal within 2 weeks of hydroxychloroquine cessation; hence, after the review of investigations, a diagnosis of hydroxychloroquine-induced agranulocytosis was made. This report considers current literature on hydroxychloroquine-induced agranulocytosis and explores the potential causes for this occurrence. PMID- 27708976 TI - The clinical significance of antiphospholipid antibodies in systemic lupus erythematosus. AB - Antiphospholipid syndrome (APS) is the association of thrombosis and/or pregnancy morbidity with antiphospholipid antibodies (aPL). Thirty to forty percent of systemic lupus erythematosus (SLE) patients are tested positive for aPL, which may have an impact on the SLE presentation, management, and prognosis. Compared with SLE patients without aPL, those with aPL have a higher prevalence of thrombosis, pregnancy morbidity, valve disease, pulmonary hypertension, livedo reticularis, thrombocytopenia, hemolytic anemia, acute/chronic renal vascular lesions, and moderate/severe cognitive impairment; worse quality of life; and higher risk of organ damage. The use of low-dose aspirin (LDA) is controversial for primary thrombosis and pregnancy morbidity prevention because of the lack of strong prospective controlled data. Similarly, the use of anticoagulation is controversial for patients with an aPL-related nephropathy. Until further studies are available, physicians should discuss the risk/benefits of LDA or anticoagulation as well as the available literature with patients.

AB - Introduction Gorham-Stout Disease (GSD) is a rare disorder of bony destruction due to lymphangiomatosis, and is often triggered by hormones. One complication of GSD is the development of chylothorax, which carries a high mortality rate. Very little experience has been published to guide management in GSD during pregnancy to optimize both fetal and maternal health. Case Study A 20-year-old woman with known GSD presented with shortness of breath at 18 weeks of pregnancy, due to bilateral chylothoraces which required daily drainage. To minimize chylous fluid formation, she was placed on bowel rest with total parenteral nutrition (limiting lipid intake) and received octreotide to decrease splanchnic blood flow and chylous fluid drainage. Treatment options were limited due to her pregnancy. Twice daily home chest tube drainage of a single lung cavity, total parenteral nutrition, octreotide, and albumin infusions allowed successful delivery of a healthy 37 weeks' gestation infant by cesarean delivery. Discussion This case illustrates the management of a rare clinical disease of bone resorption and lymphangiomatosis complicated by bilateral, refractory chylothoraces, triggered by pregnancy, in whom treatment options are limited, and the need for a multidisciplinary health care team to ensure successful maternal and fetal outcomes. PMID- 27708983 TI - Overuse Cervical Dystonia: A Case Report and Literature Review. AB - BACKGROUND: Overuse or task-specific dystonia has been described in a number of professions characterized by repetitive actions, typically affecting the upper extremities. Cervical dystonia (CD), however, has rarely been associated with overuse. CASE REPORT: We present a case report of typical CD that developed in the context of chronic repetitive movements associated with the patient's professional occupation as an office manager who spent many hours per day holding a phone to his ear. DISCUSSION: Overuse CD should be suspected when typical symptoms and signs of CD develop in the context of chronic repetitive use or overuse of cervical muscles, especially where exacerbating tasks involve asymmetric postures. PMID- 27708984 TI - Purkinje Cell Cytoplasmic Antibody (PCA-2)-related Chorea-Dystonia Syndrome. PMID- 27708982 TI - Post-hypoxic Myoclonus: Current Concepts, Neurophysiology, and Treatment. AB - BACKGROUND: Myoclonus may occur after hypoxia. In 1963, Lance and Adams described persistent myoclonus with other features after hypoxia. However, myoclonus occurring immediately after hypoxia may demonstrate different syndromic features from classic Lance-Adams syndrome (LAS). The aim of this review is to provide up to-date information about the spectrum of myoclonus occurring after hypoxia with emphasis on neurophysiological features. METHODS: A literature search was performed on PubMed database from 1960 to 2015. The following search terms were used: "myoclonus," "post anoxic myoclonus," "post hypoxic myoclonus," and "Lance Adams syndrome." The articles describing clinical features, neurophysiology, management, and prognosis of post-hypoxic myoclonus cases were included for review. RESULTS: Several reports in the literature were separated clinically into "acute post-hypoxic myoclonus," which occurred within hours of severe hypoxia, and "chronic post-hypoxic myoclonus," which occurred with some recovery of mental status as the LAS. Acute post-hypoxic myoclonus was generalized in the setting of coma. Chronic post-hypoxic myoclonus presented as multifocal cortical action myoclonus that was significantly disabling. There was overlap of neurophysiological findings for these two syndromes but also different features. Treatment options for these two distinct clinical-neurophysiologic post-hypoxic myoclonus syndromes were approached differently. DISCUSSION: The review of clinical and neurophysiological findings suggests that myoclonus after hypoxia manifests in one or a combination of distinct syndromes: acute and/or chronic myoclonus. The mechanism of post-hypoxic myoclonus may arise either from cortical and/or subcortical structures. More research is needed to clarify mechanisms and treatment of post-hypoxic myoclonus. PMID- 27708985 TI - Clinical Correlates and Drug Resistance in HIV-Infected and -Uninfected Pulmonary Tuberculosis Patients in South India. AB - OBJECTIVES: To examine demographics, clinical correlates, sputum AFB (acid fast bacilli) smear grading DOTS (Directly Observed Therapy Short Course) uptake, and drug resistance in a cohort of newly-diagnosed, smear positive pulmonary tuberculosis (TB) patients with respect to HIV status at baseline, and compare smear conversion rates, side effects and mortality after two months. DESIGN: A prospective study among 54 HIV positive and 41 HIV negative pulmonary TB patients. Data were collected via face-to-face interviews, review of medical records, and lab tests. RESULTS: HIVTB co-infected patients, though more symptomatic at baseline, showed more improvement in their symptoms compared to HIV-uninfected TB patients at follow-up. The HIV co-infected group had more prevalent perceived side effects, and sputum smear positivity was marginally higher compared to the HIV negative group at follow-up. Mortality was higher among the HIV-infected group. Both groups had high rates of resistance to first line anti-tubercular drugs, particularly isoniazid. There was no significant difference in the drug resistance patterns between the groups. CONCLUSIONS: Prompt initiation and provision of daily regimens of ATT (Anti-Tubercular treatment) along with ART (Anti-Retroviral treatment) via ART centers is urgently needed in India. As resistance to ART and/or ATT is directly linked to medication non-adherence, the use of counseling, regular reinforcement, early detection and appropriate intervention strategies to tackle this complex issue could help prevent premature mortality and development of resistance in HIV-TB co-infected patients. The high rate of isoniazid resistance might preclude its use in India as prophylaxis for latent TB in HIV infected persons as per the World Health Organization (WHO) guideline.

AB - BACKGROUND: Pegylated-interferon alpha (PegINFalpha) treatment of patients with polycythemia vera (PV) and essential thrombocythemia (ET) has resulted in long term clinical response, decreased JAK2V617F allelic burden and restoration of polyclonal hematopoiesis. The mechanisms of the beneficial effects of PegINFalpha are not clear, but available evidence suggests direct suppression of JAK2-mutated clone, induction of dormant stem cells to proliferation, and augmentation of an immune effect against PV and ET clones. METHODS: We analyzed the phenotype and frequency of peripheral blood lymphocytes (PBL) from PegINFalpha treated patients and compared them to patients treated with hydroxyurea (HU). Samples collected at various time points before and during treatment were analyzed using multicolor flow cytometry. RESULTS: We found that PegINFalpha increased the frequency of peripheral blood CD4+ Foxp3+ regulatory T cells (Treg). Highly suppressive Treg, characterized by co-expression of CD39 and HLA-DR, were also increased in PBL from PegINFalpha treated patients. We observed an augmentation of cycling CD8+ T cells, NK cells, and of poorly activated CD38+CD8+ T cells. Our results also suggest that PegINFalpha increased the frequency of PD-1+ CD4+ helper cells and PD-1+ CD4+ Foxp3+ Treg cells. None of these changes were present in HU treated patients. We analyzed the correlation between changes in different T cell populations in the peripheral blood with the changes in JAK2V617F allelic burden in clonal granulocytes. Augmentation of Ki-67+ Treg, HLA-DR+ CD39+ Treg, Helios+ Treg and HLA-DR+ CD38+ CD8+ T cells correlated with an increase in JAK2V617F allelic burden. We also found a positive correlation between PD-1+ Treg and JAK2V617F allelic burden; however, the number of available patients was small (n = 7). CONCLUSIONS: We report marked changes in frequencies of PBL subsets after PegINFalpha treatment, suggesting an immunomodulatory effect by PegINFalpha. Generation of a more suppressive immune response, as measured by an increase in highly suppressive Treg and poorly activated CD8+ T cells, correlated with a poor molecular response. In this study, we have not identified changes in the PBL that would indicate the presence of an effective anti-tumor response.Trial registration NCT01259856, December 7. 2010 and NCT01259817, December 6. 2010, Grant #1P01CA108671-O1A2, July 17. 2006, Sponsor: MPDRC/NIH, NCI-2012-00269, January 12. 2011 and NCI-2012-00268, January 12. 2011.

AB - The traditional medicine in Africa in general and specifically in Cameroon does not manage diabetes and arterial hypertension very well. Yet, these pathologies are becoming more prevalent among the populations that need adequate knowledge to fight against them. Therefore the present study was designed to determine the knowledge, attitudes and practices of indigenous people regarding diabetes and hypertension control, and to assess the epidemiological aspects of these diseases in order to reinforce their health education and promote a better health care through traditional medicine. To achieve this objective, 1,131 households including 70 traditional healers, 114 diabetics, 167 hypertensive patients, 30 hypertensive patients-diabetics and other Cameroonians were questioned on their ethnomedical knowledge of diabetes and arterial hypertension. Fifty-eight randomly distributed tribes were taking in account. The elucidation of anthropological and epidemiological aspects of diabetes and hypertension improved the beliefs of indigenous people and facilitated the modernization of diabetes and hypertension comprehension that remained focused on the elucidation of diseases' causes and complications, as well as on the behaviors that could help translate biomedical terms into locally meaningful metaphors.

AB - It is recognized that anthropogenic factors have had a major impact on carbon fluxes from land to the ocean during the past two centuries. However, little is known about how future changes in climate, atmospheric CO2, and land use may affect riverine carbon fluxes over the 21st century. Using a coupled hydrological biogeochemical model, the Dynamic Land Ecosystem Model, this study examines potential changes in dissolved inorganic carbon (DIC) export from the Mississippi River basin to the Gulf of Mexico during 2010-2099 attributable to climate related conditions (temperature and precipitation), atmospheric CO2, and land use change. Rates of annual DIC export are projected to increase by 65% under the high emission scenario (A2) and 35% under the low emission scenario (B1) between the 2000s and the 2090s. Climate-related changes along with rising atmospheric CO2 together would account for over 90% of the total increase in DIC export throughout the 21st century. The predicted increase in DIC export from the Mississippi River basin would alter chemistry of the coastal ocean unless appropriate climate mitigation actions are taken in the near future.

AB - Nitrogen dioxide retrievals from the Aura/Ozone Monitoring Instrument (OMI) have been used extensively over the past decade, particularly in the study of tropospheric air quality. Recent comparisons of OMI NO2 with independent data sets and models suggested that the OMI values of slant column density (SCD) and stratospheric vertical column density (VCD) in both the NASA OMNO2 and Royal Netherlands Meteorological Institute DOMINO products are too large, by around 10 40%. We describe a substantially revised spectral fitting algorithm, optimized for the OMI visible light spectrometer channel. The most important changes comprise a flexible adjustment of the instrumental wavelength shifts combined with iterative removal of the ring spectral features; the multistep removal of instrumental noise; iterative, sequential estimates of SCDs of the trace gases in the 402-465 nm range. These changes reduce OMI SCD(NO2) by 10-35%, bringing them much closer to SCDs retrieved from independent measurements and models. The revised SCDs, submitted to the stratosphere-troposphere separation algorithm, give tropospheric VCDs ~10-15% smaller in polluted regions, and up to ~30% smaller in unpolluted areas. Although the revised algorithm has been optimized specifically for the OMI NO2 retrieval, our approach could be more broadly applicable. PMID- 27708990 TI - MODIS comparisons with northeastern Pacific in situ stratocumulus microphysics. AB - Vertical sounding measurements within stratocumuli during two aircraft field campaigns, Marine Stratus/stratocumulus Experiment (MASE) and Physics of Stratocumulus Top (POST), are used to validate Moderate Resolution Imaging Spectroradiometer (MODIS) cloud optical thickness (COT), cloud liquid water path (LWP), and cloud effective radius (re). In situ COT, LWP, and re were calculated using 5 m vertically averaged droplet probe measurements of complete vertical cloud penetrations. MODIS COT, LWP, and re 1 km pixels were averaged along these penetrations. COT comparisons in POST showed strong correlations and a near 1:1 relationship. In MASE, comparisons showed strong correlations; however, MODIS COT exceeded in situ COT, likely due to larger temporal differences between MODIS and in situ measurements. LWP comparisons between two cloud probes show good agreement for POST but not MASE, giving confidence to POST data. Both projects provided strong LWP correlations but MODIS exceeded in situ by 14-36%. MODIS in situ re correlations were strong, but MODIS 2.1 um re exceeded in situ re, which contributed to LWP bias; in POST, MODIS re was 20-30% greater than in situ re. Maximum in situ re near cloud top showed comparisons nearer 1:1. Other MODIS re bands (3.7 um and 1.6 um) showed similar comparisons. Temporal differences between MODIS and in situ measurements, airplane speed differences, and cloud probe artifacts were likely causes of weaker MASE correlations. POST COT comparison was best for temporal differences under 20 min. POST data validate MODIS COT but it also implies a positive MODIS re bias that propagates to LWP while still capturing variability. PMID- 27708991 TI - Using a multiwavelength suite of microwave instruments to investigate the microphysical structure of deep convective cores. AB - Due to the large natural variability of its microphysical properties, the characterization of solid precipitation is a longstanding problem. Since in situ observations are unavailable in severe convective systems, innovative remote sensing retrievals are needed to extend our understanding of such systems. This study presents a novel technique able to retrieve the density, mass, and effective diameter of graupel and hail in severe convection through the combination of airborne microwave remote sensing instruments. The retrieval is applied to measure solid precipitation properties within two convective cells observed on 23-24 May 2014 over North Carolina during the IPHEx campaign by the NASA ER-2 instrument suite. Between 30 and 40 degrees of freedom of signal are associated with the measurements, which is insufficient to provide full microphysics profiling. The measurements have the largest impact on the retrieval of ice particle sizes, followed by ice water contents. Ice densities are mainly driven by a priori assumptions, though low relative errors in ice densities suggest that in extensive regions of the convective system, only particles with densities larger than 0.4 g/cm3 are compatible with the observations. This is in agreement with reports of large hail on the ground and with hydrometeor classification derived from ground-based polarimetric radars observations. This work confirms that multiple scattering generated by large ice hydrometeors in deep convection is relevant for airborne radar systems already at Ku band. A fortiori, multiple scattering will play a pivotal role in such conditions also for Ku band spaceborne radars (e.g., the GPM Dual Precipitation Radar). PMID- 27708992 TI - Surface mass balance contributions to acceleration of Antarctic ice mass loss during 2003-2013. AB - Recent observations from satellite gravimetry (the Gravity Recovery and Climate Experiment (GRACE) mission) suggest an acceleration of ice mass loss from the Antarctic Ice Sheet (AIS). The contribution of surface mass balance changes (due to variable precipitation) is compared with GRACE-derived mass loss acceleration by assessing the estimated contribution of snow mass from meteorological reanalysis data. We find that over much of the continent, the acceleration can be explained by precipitation anomalies. However, on the Antarctic Peninsula and other parts of West Antarctica, mass changes are not explained by precipitation and are likely associated with ice discharge rate increases. The total apparent GRACE acceleration over all of the AIS between 2003 and 2013 is -13.6 +/- 7.2 Gt/yr2. Of this total, we find that the surface mass balance component is -8.2 +/ 2.0 Gt/yr2. However, the GRACE estimate appears to contain errors arising from the atmospheric pressure fields used to remove air mass effects. The estimated acceleration error from this effect is about 9.8 +/- 5.8 Gt/yr2. Correcting for this yields an ice discharge acceleration of -15.1 +/- 6.5 Gt/yr2. PMID- 27708993 TI - The Dst index underestimates the solar cycle variation of geomagnetic activity. AB - It is known that the correction of the Kyoto Dst index for the secular variation of the Earth's internal field produces a discontinuity in the Kyoto Dst index at the end of each year. We show that this secular correction also introduces a significant baseline error to the Kyoto Dst index that leads to an underestimate of the solar cycle variation of geomagnetic activity and of the strength of the ring current as measured by the Kyoto Dst index. Thus, the average value of the Kyoto Dst index would be approximately 13 nT more negative for the active year 2003 compared to quiet years 2006 and 2009 if the Kyoto Dst index properly measured the effects of the ring current and other currents that influence the Dst observatories. Discontinuities in the Kyoto Dst index at the end of each year have an average value of about 5 nT, but the discontinuity at the end of year 2002 was approximately 12 nT, and the discontinuity at the end of year 1982 may have been as large as 20 nT.

AB - Reserving interior void space in the cable-like structure of multiwalled carbon nanotubes-in-SnO2-in-carbon layer (MWNTs@SnO2@C) is reported for the first time. Such a design enables the structure performing excellent for Li and Na storage, which benefit from the good electrical conductivity of MWNTs and carbon layer as well as the reserved void space to accommodate the volume changes of SnO2. PMID- 27708998 TI - Understanding Inhomogeneous Reactions in Li-Ion Batteries: Operando Synchrotron X Ray Diffraction on Two-Layer Electrodes. AB - To understand inhomogeneous reactions perpendicular to the current collector in an electrode for batteries, a method combining operando synchrotron X-ray diffraction and two-layer electrodes with different porosities is developed. The two layers are built using two different active materials (LiNi0.80Co0.15Al0.05O2 and LiMn2O4), therefore, tracing each diffraction pattern reveals which active material is reacting during the electrochemical measurement in transmission mode. The results demonstrate that the active material close to the separator is obviously more active than that one close to the current collector in the case of low porosity electrodes. This inhomogeneity should be due to the rate-limitation and especially to low average ionic conductivity of the electrolyte in the porous electrode because the current flows first mainly into the electrode regions close to the separator. The inhomogeneity is found to be mitigated by the adjustment of the electrode density and thus porosity. Hence, the novel operando method reveals a clear inhomogeneous reaction perpendicular to the current collector. PMID- 27708997 TI - Phases Hybriding and Hierarchical Structuring of Mesoporous TiO2 Nanowire Bundles for High-Rate and High-Capacity Lithium Batteries. AB - A hierarchical mesoporous TiO2 nanowire bundles (HM-TiO2-NB) superstructure with amorphous surface and straight nanochannels has been designed and synthesized through a templating method at a low temperature under acidic and wet conditions. The obtained HM-TiO2-NB superstructure demonstrates high reversible capacity, excellent cycling performance, and superior rate capability. Most importantly, a self-improving phenomenon of Li+ insertion capability based on two simultaneous effects, the crystallization of amorphous TiO2 and the formation of Li2Ti2O4 crystalline dots on the surface of TiO2 nanowires, has been clearly revealed through ex situ transmission electron microcopy (TEM), high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD), Raman, and X ray photoelectron spectroscopy (XPS) techniques during the Li+ insertion process. When discharged for 100 cycles at 1 C, the HM-TiO2-NB exhibits a reversible capacity of 174 mA h g-1. Even when the current density is increased to 50 C, a very stable and extraordinarily high reversible capacity of 96 mA h g-1 can be delivered after 50 cycles. Compared to the previously reported results, both the lithium storage capacity and rate capability of our pure TiO2 material without any additives are among the highest values reported. The advanced electrochemical performance of these HM-TiO2-NB superstructures is the result of the synergistic effect of hybriding of amorphous and crystalline (anatase/rutile) phases and hierarchically structuring of TiO2 nanowire bundles. Our material could be a very promising anodic material for lithium-ion batteries. PMID- 27708999 TI - Disorder Control in Crystalline GeSb2Te4 Using High Pressure. AB - Electronic phase-change memory devices take advantage of the different resistivity of two states, amorphous and crystalline, and the swift transitions between them in active phase-change materials (PCMs). In addition to these two distinct phases, multiple resistive states can be obtained by tuning the atomic disorder in the crystalline phase with heat treatment, because the disorder can lead to the localization of the electronic states and, thus, hamper the electron transport. The goal of this work is to achieve and explore multiple disordered configurations in PCMs by applying high pressure. Large-scale ab initio molecular dynamics simulations demonstrate that pressure can lower the energy barrier for the antisite migration in crystalline PCMs. The accumulation of these antisite atoms largely increases the compositional disorder, adding localized electronic states near the conduction band. The disorder-induced electron localization triggered by pressure is a novel way to modulate the properties of materials. Furthermore, the random distortion of the lattice induced by the compositional disorder provides a new mechanism that contributes to the amorphization of crystalline PCMs at high pressure.

PMID- 27709005 TI - Renal drug transporters and their significance in drug-drug interactions. AB - The kidney is a vital organ for the elimination of therapeutic drugs and their metabolites. Renal drug transporters, which are primarily located in the renal proximal tubules, play an important role in tubular secretion and reabsorption of drug molecules in the kidney. Tubular secretion is characterized by high clearance capacities, broad substrate specificities, and distinct charge selectivity for organic cations and anions. In the past two decades, substantial progress has been made in understanding the roles of transporters in drug disposition, efficacy, toxicity and drug-drug interactions (DDIs). In the kidney, several transporters are involved in renal handling of organic cation (OC) and organic anion (OA) drugs. These transporters are increasingly recognized as the target for clinically significant DDIs. This review focuses on the functional characteristics of major human renal drug transporters and their involvement in clinically significant DDIs. PMID- 27709006 TI - An update on the role of intestinal cytochrome P450 enzymes in drug disposition. AB - Oral administration is the most commonly used route for drug treatment. Intestinal cytochrome P450 (CYP)-mediated metabolism can eliminate a large proportion of some orally administered drugs before they reach systemic circulation, while leaving the passage of other drugs unimpeded. A better understanding of the ability of intestinal P450 enzymes to metabolize various clinical drugs in both humans and preclinical animal species, including the identification of the CYP enzymes expressed, their regulation, and the relative importance of intestinal metabolism compared to hepatic metabolism, is important for improving bioavailability of current drugs and new drugs in development. Here, we briefly review the expression of drug-metabolizing P450 enzymes in the small intestine of humans and several preclinical animal species, and provide an update of the various factors or events that regulate intestinal P450 expression, including a cross talk between the liver and the intestine. We further compare various clinical and preclinical approaches for assessing the impact of intestinal drug metabolism on bioavailability, and discuss the utility of the intestinal epithelium-specific NADPH-cytochrome P450 reductase-null (IECN) mouse as a useful model for studying in vivo roles of intestinal P450 in the disposition of orally administered drugs. PMID- 27709007 TI - Isoniazid metabolism and hepatotoxicity. AB - Isoniazid (INH) is highly effective for the management of tuberculosis. However, it can cause liver injury and even liver failure. INH metabolism has been thought to be associated with INH-induced liver injury. This review summarized the metabolic pathways of INH and discussed their associations with INH-induced liver injury. PMID- 27709009 TI - Fatty liver diseases, bile acids, and FXR. AB - The prevalence of nonalcoholic fatty liver disease (NAFLD) worldwide has increased at an alarming rate, which will likely result in enormous medical and economic burden. NAFLD presents as a spectrum of liver diseases ranging from simple steatosis, nonalcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and even to hepatocellular carcinoma (HCC). A comprehensive understanding of the mechanism(s) of NAFLD-to-NASH transition remains elusive with various genetic and environmental susceptibility factors possibly involved. An understanding of the mechanism may provide novel strategies in the prevention and treatment to NASH. Abnormal regulation of bile acid homeostasis emerges as an important mechanism to liver injury. The bile acid homeostasis is critically regulated by the farnesoid X receptor (FXR) that is activated by bile acids. FXR has been known to exert tissue-specific effects in regulating bile acid synthesis and transport. Current investigations demonstrate FXR also plays a principle role in regulating lipid metabolism and suppressing inflammation in the liver. Therefore, the future determination of the molecular mechanism by which FXR protects the liver from developing NAFLD may shed light to the prevention and treatment of NAFLD. PMID- 27709011 TI - Exposure to inorganic arsenic can lead to gut microbe perturbations and hepatocellular carcinoma. AB - Arsenic is a carcinogenic environmental factor found in food and drinking water around the world. The mechanisms in which arsenic alters homeostasis are not fully understood. Over the past few decades, light has been shed on varying mechanisms in which arsenic induces cancer. Such mechanisms include gut microbe perturbations, genotoxic effects, and epigenetic modification. Gut microbe perturbations have been shown to increase the level of pathogen-associated molecular patterns such as lipopolysaccharide (LPS) leading to uncontained inflammation. Increase in inflammation is the major factor in cirrhosis leading to hepatocellular carcinoma. Alterations in gut permeability and metabolites have also been observed as a fallout of arsenic induced gut microbe modification. The guts proximity and interaction through portal flow make the liver susceptible to gut perturbations and ensuing inflammatory responses. Genotoxic and epigenetic dysregulation induced by arsenic and its toxic metabolites present a more direct mechanism that works synergistically with gut microbe perturbations to induce the incidence of cancers. These pathways combined could be some of the main causes of arsenic-induced carcinogenesis. PMID- 27709008 TI - Crosstalk of HNF4alpha with extracellular and intracellular signaling pathways in the regulation of hepatic metabolism of drugs and lipids. AB - The liver is essential for survival due to its critical role in the regulation of metabolic homeostasis. Metabolism of xenobiotics, such as environmental chemicals and drugs by the liver protects us from toxic effects of these xenobiotics, whereas metabolism of cholesterol, bile acids (BAs), lipids, and glucose provide key building blocks and nutrients to promote the growth or maintain the survival of the organism. As a well-established master regulator of liver development and function, hepatocyte nuclear factor 4 alpha (HNF4alpha) plays a critical role in regulating a large number of key genes essential for the metabolism of xenobiotics, metabolic wastes, and nutrients. The expression and activity of HNF4alpha is regulated by diverse hormonal and signaling pathways such as growth hormone, glucocorticoids, thyroid hormone, insulin, transforming growth factor beta, estrogen, and cytokines. HNF4alpha appears to play a central role in orchestrating the transduction of extracellular hormonal signaling and intracellular stress/nutritional signaling onto transcriptional changes in the liver. There have been a few reviews on the regulation of drug metabolism, lipid metabolism, cell proliferation, and inflammation by HNF4alpha. However, the knowledge on how the expression and transcriptional activity of HNF4alpha is modulated remains scattered. Herein I provide comprehensive review on the regulation of expression and transcriptional activity of HNF4alpha, and how HNF4alpha crosstalks with diverse extracellular and intracellular signaling pathways to regulate genes essential in liver pathophysiology. PMID- 27709014 TI - Role of farnesoid X receptor in establishment of ontogeny of phase-I drug metabolizing enzyme genes in mouse liver. AB - The expression of phase-I drug metabolizing enzymes in liver changes dramatically during postnatal liver maturation. Farnesoid X receptor (FXR) is critical for bile acid and lipid homeostasis in liver. However, the role of FXR in regulating ontogeny of phase-I drug metabolizing genes is not clear. Hence, we applied RNA sequencing to quantify the developmental expression of phase-I genes in both Fxr null and control (C57BL/6) mouse livers during development. Liver samples of male C57BL/6 and Fxr-null mice at 6 different ages from prenatal to adult were used. The Fxr-null showed an overall effect to diminish the "day-1 surge" of phase-I gene expression, including cytochrome P450s at neonatal ages. Among the 185 phase I genes from 12 different families, 136 were expressed, and differential expression during development occurred in genes from all 12 phase-I families, including hydrolysis: carboxylesterase (Ces), paraoxonase (Pon), and epoxide hydrolase (Ephx); reduction: aldoketo reductase (Akr), quinone oxidoreductase (Nqo), and dihydropyrimidine dehydrogenase (Dpyd); and oxidation: alcohol dehydrogenase (Adh), aldehyde dehydrogenase (Aldh), flavin monooxygenases (Fmo), molybdenum hydroxylase (Aox and Xdh), cytochrome P450 (P450), and cytochrome P450 oxidoreductase (Por). The data also suggested new phase-I genes potentially targeted by FXR. These results revealed an important role of FXR in regulation of ontogeny of phase-I genes. PMID- 27709012 TI - PXR variants: the impact on drug metabolism and therapeutic responses. AB - The pregnane X receptor (PXR) plays an important and diverse role in mediating xenobiotic induction of drug-metabolizing enzymes and transporters. Several protein isoforms of PXR exist, and they have differential transcriptional activity upon target genes; transcript variants 3 (PXR3) and 4 (PXR4) do not induce target gene expression, whereas transcript variants 1 (PXR1) and 2 (PXR2) respond to agonist by activating target gene expression. PXR protein variants also display differences in protein-protein interactions; PXR1 interacts with p53, whereas PXR3 does not. Furthermore, the transcript variants of PXR that encode these protein isoforms are differentially regulated by methylation and deletions in the respective promoters of the variants, and their expression differs in various human cancers and also in cancerous tissue compared to adjacent normal tissues. PXR1 and PXR4 mRNA are downregulated by methylation in cancerous tissue and have divergent effects on cellular proliferation when ectopically overexpressed. Additional detailed and comparative mechanistic studies are required to predict the effect of PXR transcript variant expression on carcinogenesis, therapeutic response, and the development of toxicity. PMID- 27709010 TI - Insights into CYP2B6-mediated drug-drug interactions. AB - Mounting evidence demonstrates that CYP2B6 plays a much larger role in human drug metabolism than was previously believed. The discovery of multiple important substrates of CYP2B6 as well as polymorphic differences has sparked increasing interest in the genetic and xenobiotic factors contributing to the expression and function of the enzyme. The expression of CYP2B6 is regulated primarily by the xenobiotic receptors constitutive androstane receptor (CAR) and pregnane X receptor (PXR) in the liver. In addition to CYP2B6, these receptors also mediate the inductive expression of CYP3A4, and a number of important phase II enzymes and drug transporters. CYP2B6 has been demonstrated to play a role in the metabolism of 2%-10% of clinically used drugs including widely used antineoplastic agents cyclophosphamide and ifosfamide, anesthetics propofol and ketamine, synthetic opioids pethidine and methadone, and the antiretrovirals nevirapine and efavirenz, among others. Significant inter-individual variability in the expression and function of the human CYP2B6 gene exists and can result in altered clinical outcomes in patients receiving treatment with CYP2B6-substrate drugs. These variances arise from a number of sources including genetic polymorphism, and xenobiotic intervention. In this review, we will provide an overview of the key players in CYP2B6 expression and function and highlight recent advances made in assessing clinical ramifications of important CYP2B6 mediated drug-drug interactions. PMID- 27709013 TI - A brief history of the discovery of PXR and CAR as xenobiotic receptors. AB - The nuclear receptors pregnane X receptor (PXR) and constitutive androstane receptor (CAR) were cloned and/or established as xenobiotic receptors in 1998. Due to their activities in the transcriptional regulation of phase I and phase II enzymes as well as drug transporters, PXR and CAR have been defined as the master regulators of xenobiotic responses. The discovery of PXR and CAR provides the essential molecular basis by which drugs and other xenobiotic compounds regulate the expression of xenobiotic enzymes and transporters. This article is intended to provide a historical overview on the discovery of PXR and CAR as xenobiotic receptors. PMID- 27709015 TI - Tissue distribution and tumor uptake of folate receptor-targeted epothilone folate conjugate, BMS-753493, in CD2F1 mice after systemic administration. AB - To assess targeting of an epothilone folate conjugate (BMS-753493) to the folate receptor (FR)-overexpressed tumor in mice bearing both FR+ and FR- tumors, a series of experiments were conducted by quantitative whole-body autoradiography (QWBA) and LC-MS/MS following i.v. administration of BMS-753493 or its active moiety, BMS-748285 in mice bearing FR+ (98M109) and FR- (M109) tumors. QWBA showed [3H]BMS-753493-derived radioactivity was extensively distributed to various tissues. The FR over-expressing 98M109 tumors showed consistently higher level of radioactivity than FR-negative tumors (i.e., M109 tumors) up to 48 h post dose of [3H]BMS-753493, despite the magnitude of difference between the tumors is relatively small (generally 3~5-fold). The radioactivity level in 98M109 tumors was 2~12-fold of normal tissues except intestine/content at 48 h post dose. No selective radioactivity uptake into 98M109 tumors over M109 or normal tissues was observed after i.v. administration of the active epothilone, [3H]BMS-748285. LC-MS/MS measurements demonstrated that the concentrations of BMS 748285, presumably from hydrolysis of the folate conjugate, in 98M109 tumors were greater than those in M109 tumors after i.v. administration of BMS-753493 (2-3 fold) whereas no differential uptake in the tumors following BMS-748285 administration. Those data were consistent with radioactivity determinations. Those results demonstrated that the folate conjugation in BMS-753493 enabled moderately preferential distribution of the active epothilone to FR over expressing 98M109 tumors, thereby supporting targeted delivery of cytotoxics through the folate receptor. PMID- 27709016 TI - Effect of age on the pharmacokinetics of polymorphic nimodipine in rats after oral administration. AB - The previous investigation has proved that their existed pharmacokinetic difference between the different crystal forms of the polymorphic drugs after oral administration. However, no systemic investigations have been made on the change of this pharmacokinetic difference, resulted either from the physiological or from the pathological factors. In this paper, we used polymorphic nimodipine (Nim) as a model drug and investigated the effect of age difference (2- and 9 month old) on the pharmacokinetics after oral delivery in rats. As the results shown, for L-form of Nim (L-Nim), the AUC0-24 h in 2-month-old rats was 343.68+/ 47.15 ng.h/mL, which is 23.36% higher than that in 9-month-old rats. For H-form of Nim (H-Nim), the AUC0-24 h in 2-month-old rats was 140.91+/-19.47 ng.h/mL, which is 54.64% higher than that in 9-month-old rats. The AUC0-24 h ratio between H-Nim and L-Nim was 2.44 in 2-month-old rats and 3.06 in 9-month-old rats. Since age difference could result in unparallelled change of the absorption and bioavailability of the polymorphic drugs, the results in this experiment are of value for further investigation of crystal form selection in clinical trials and rational clinical application of the polymorphic drugs. PMID- 27709017 TI - Characterizing drug-metabolizing enzymes and transporters that are bona fide CAR target genes in mouse intestine. AB - Intestine is responsible for the biotransformation of many orally-exposed chemicals. The constitutive androstane receptor (CAR/Nr1i3) is known to up regulate many genes encoding drug-metabolizing enzymes and transporters (drug processing genes/DPGs) in liver, but less is known regarding its effect in intestine. Sixty-day-old wild-type and Car-/- mice were administered the CAR ligand TCPOBOP or vehicle once daily for 4 days. In wild-type mice, Car mRNA was down-regulated by TCPOBOP in liver and duodenum. Car-/- mice had altered basal intestinal expression of many DPGs in a section-specific manner. Consistent with the liver data (Aleksunes and Klaassen, 2012), TCPOBOP up-regulated many DPGs (Cyp2b10, Cyp3a11, Aldh1a1, Aldh1a7, Gsta1, Gsta4, Gstm1-m4, Gstt1, Ugt1a1, Ugt2b34, Ugt2b36, and Mrp2-4) in specific sections of small intestine in a CAR dependent manner. However, the mRNAs of Nqo1 and Papss2 were previously known to be up-regulated by TCPOBOP in liver but were not altered in intestine. Interestingly, many known CAR-target genes were highest expressed in colon where CAR is minimally expressed, suggesting that additional regulators are involved in regulating their expression. In conclusion, CAR regulates the basal expression of many DPGs in intestine, and although many hepatic CAR-targeted DPGs were bona fide CAR-targets in intestine, pharmacological activation of CAR in liver and intestine are not identical.

PMID- 27709018 TI - Development of a mechanism-based pharmacokinetic/pharmacodynamic model to characterize the thermoregulatory effects of serotonergic drugs in mice. AB - We have shown recently that concurrent harmaline, a monoamine oxidase-A inhibitor (MAOI), potentiates serotonin (5-HT) receptor agonist 5-methoxy-N,N dimethyltryptamine (5-MeO-DMT)-induced hyperthermia. The objective of this study was to develop an integrated pharmacokinetic/pharmacodynamic (PK/PD) model to characterize and predict the thermoregulatory effects of such serotonergic drugs in mice. Physiological thermoregulation was described by a mechanism-based indirect-response model with adaptive feedback control. Harmaline-induced hypothermia and 5-MeO-DMT-elicited hyperthermia were attributable to the loss of heat through the activation of 5-HT1A receptor and thermogenesis via the stimulation of 5-HT2A receptor, respectively. Thus serotonergic 5-MeO-DMT-induced hyperthermia was readily distinguished from handling/injection stress-provoked hyperthermic effects. This PK/PD model was able to simultaneously describe all experimental data including the impact of drug-metabolizing enzyme status on 5 MeO-DMT and harmaline PK properties, and drug- and stress-induced simple hypo/hyperthermic and complex biphasic effects. Furthermore, the modeling results revealed a 4-fold decrease of apparent SC50 value (1.88-0.496 umol/L) for 5-MeO DMT when harmaline was co-administered, providing a quantitative assessment for the impact of concurrent MAOI harmaline on 5-MeO-DMT-induced hyperthermia. In addition, the hyperpyrexia caused by toxic dose combinations of harmaline and 5 MeO-DMT were linked to the increased systemic exposure to harmaline rather than 5 MeO-DMT, although the body temperature profiles were mispredicted by the model. The results indicate that current PK/PD model may be used as a new conceptual framework to define the impact of serotonergic agents and stress factors on thermoregulation. PMID- 27709021 TI - Fungistatic effect of hydroxychloroquine, lessons from a case. AB - A 50-year-old male was prescribed with hydroxychloroquine (HCQ) after osteoarthritis was diagnosed. He had an old nail infection of Aspergillus niger. A remarkable improvement of the symptoms of fungal nail infection was seen after about four weeks of treatment with HCQ. It was very hard to detect the symptoms in the end of the second month of the treatment, both in the finger and toe nails. The symptoms were clearly recurred after HCQ was discontinued. PMID- 27709019 TI - 17beta-Estradiol up-regulates UDP-glucuronosyltransferase 1A9 expression via estrogen receptor alpha. AB - UDP-glucuronosyltransferase 1A9 (UGT1A9) is a major phase II enzyme responsible for elimination of drugs and endogenous molecules. Clinical data have shown increased elimination of UGT1A9 substrates in pregnant women or oral contraceptive users, but the role of estrogen in the regulation of UGT1A9 expression remains unknown. In this study, we investigated the effect of 17beta estradiol (E2) on UGT1A9 expression and the role of ERalpha in the transcriptional regulation of UGT1A9. E2 significantly increased UGT1A9 promoter activity in HepG2 cells in the presence of ERalpha. UGT1A9 induction by E2 was abrogated by antiestrogen ICI182,780 in HepG2 cells that constitutively express ERalpha. Results from transient transfection of ERalpha mutants into HepG2 cells demonstrated that mutation at DNA-binding domain of ERalpha abrogates increased UGT1A9 promoter activity by E2. Deletion and mutation assays of UGT1A9 promoter revealed a putative ERE located within -2262/-1987 region. Examination of healthy human liver tissues revealed significantly higher UGT1A9 expression in women as compared to men. Together, these findings provide a mechanistic basis for the previous clinical reports and may shed a light on identifying sources for inter individual variability in UGT1A9-mediated drug metabolism. PMID- 27709022 TI - Arthroscopic Repair of Inferior Labrum Anterior to Posterior Lesions of the Shoulder Using a Combined "Double-Pulley" Simple Knot Technique. AB - Inferior labrum anterior to posterior lesions as an isolated injury or as part of an extensive traumatic labral tear are uncommon and may present as multidirectional instability of the shoulder. These lesions are hard to visualize radiographically and many times are diagnosed only during surgery. Arthroscopic repair of these lesions requires advanced arthroscopic skills and is required for restoration of glenohumeral stability. We report a combined double-pulley simple knot technique that anatomically reconstructs the inferior labrum while overcoming the typical technical challenges, providing a large footprint for healing along the inferior glenoid rim and minimizing the amount of suture material in direct contact with the articular cartilage and the risk of knot migration. PMID- 27709023 TI - Percutaneous Reconstruction of the Anterolateral Ligament of the Knee With a Polyester Tape. AB - Recent advances in surgeons' understanding of the anatomic, biomechanical, and radiologic features of the anterolateral ligament (ALL) of the knee have led to an increased interest in reconstruction of this structure as part of the management of knee instability. Even without any technical flaws and proper positioning of the bone tunnels, there is a small subset of patients, approximately 7% of all patients, who experience some residual anterolateral rotational instability after anterior cruciate ligament reconstruction. For this reason, some researchers have turned again toward the anterolateral aspect of the knee and specifically the ALL. In this technical note, the surgical steps for percutaneous reconstruction of ALL of the knee using a polyester tape are described. PMID- 27709024 TI - Revision Lapidus Arthrodesis by Bone Endoscopy. AB - Revision arthrodesis is indicated in symptomatic nonunion of the first tarsometatarsal joint. Revision by first tarsometatarsal arthroscopy cannot deal with the dilated screw tract and associated bone cysts. Revision by bone endoscopy is indicated in symptomatic nonunion of the first tarsometatarsal joint, which is previously fixed by transarticular screw along with loosening of the screw and bone cyst formation. The screw tract makes up the portal tract, with the proximal and distal ends of the tract corresponding to the proximal and distal portals, respectively. In this technical note, we describe zonal debridement and bone grafting of the bone cysts, nonunion site, and the screw tract via the bone endoscopy. This can resolve all the co-pathologies of nonunion of the first tarsometatarsal fusion. PMID- 27709025 TI - Arthroscopic Radial Head Implant Removal and Resection. AB - Displaced radial head fractures are treated with open reduction and internal fixation using implants. Failure of fixation may occur in the presence of comminution and in multifragmentary fractures; open surgical approaches are necessary for removal of the implants and radial head resection. Arthroscopic radial head resection has been described as a minimally invasive and effective treatment for failed radial head fracture fixation; however, periarticular adhesions and prominent implants add to the complexity and technical difficulty of the procedure. The described technique uses 3 portals for adhesiolysis, implant removal, and radial head resection. Resection is performed in stages; smaller-diameter instruments are used to gain and improve access, and larger resectors are used subsequently. Adequacy of resection is assessed arthroscopically and with biplanar imaging. The arthroscopic technique avoids the need for an open surgical approach and prevents subsequent morbidity. In addition, the rehabilitation time is shorter and patient satisfaction is high. PMID- 27709026 TI - Integral Suture-Handling Techniques for Arthroscopic Sliding Knots. AB - In arthroscopic tissue repair, the final step is achieving adequate tissue approximation with a secure knot. The sliding knot is widely preferred over the nonsliding knot, with numerous publications describing knot configurations. However, in the literature there are few published descriptions of suture handling techniques, even though they are fundamental to arthroscopic knot tying. We describe integral suture-handling techniques for arthroscopic sliding knots to improve the surgeon's performance in knot tying. PMID- 27709027 TI - "Owl" Technique for All-Arthroscopic Augmentation of a Massive or Large Rotator Cuff Tear With Extracellular Matrix Graft. AB - Despite the vast improvement in techniques and technology for arthroscopic rotator cuff surgery, repairs of massive and large tears remain challenging because they are associated with significantly high failure rates. In recent years, patch augmentation has gained popularity as a technique to decrease these high failure rates. Arthroscopic patch augmentation of rotator cuff repair, however, is technically difficult. The purpose of this report is to describe a simple and reproducible technique for all-arthroscopic extracellular matrix graft augmentation. With this technique, which we refer to as the "owl" technique because the prepared extracellular augment resembles an owl, there are relatively few suture ends involved; therefore, augment introduction is straightforward with a reduced risk of suture ends becoming tangled. In addition, the way in which our augmentation is prepared helps to prevent it from becoming bunched up when being secured. PMID- 27709028 TI - Distal Femoral Osteotomy: Lateral Opening Wedge Technique. AB - Coronal limb malalignment is a significant contributor to asymmetric joint wear, gait abnormalities, and the development and progression of degenerative joint disease. Osteotomies about the knee were developed to realign the mechanical axis of the limb to unload the affected compartment. Valgus malalignment is less common than varus malalignment, but can contribute to a variety of clinical conditions, including lateral compartment cartilage defects and arthritis, lateral patellofemoral instability, and medial collateral ligament laxity. In this article, we describe our preferred operative technique for a lateral opening wedge varus-producing distal femoral osteotomy to correct mild to moderate valgus malalignment. PMID- 27709029 TI - Basic Shoulder Arthroscopy: Beach Chair Patient Positioning. AB - Shoulder arthroscopy is an orthopaedic procedure that has grown significantly in popularity over the last 40 years. The 2 principle patient positions during shoulder arthroscopy include the beach chair position and lateral decubitus position. This Technical Note details the operating room setup for shoulder arthroscopy in the beach chair position. Proper positioning for this procedure will minimize potential complications and facilitate ease of surgical intervention. PMID- 27709030 TI - Anatomic Arthroscopic Ligamentum Teres Reconstruction for Hip Instability. AB - There has been growing interest in recent years on the functional importance of the ligamentum teres and its role in hip stability. Partial or complete tearing has previously been treated with debridement or radiofrequency ablation with good results; however, a subset of patients will continue to experience persistent pain or instability with injury to this structure. Advances in arthroscopic instruments and techniques have led to our ability to provide improved care for these patients by performing a ligamentum teres reconstruction. The purpose of this technical note is to describe our method of ligamentum teres reconstruction with a tibialis anterior allograft. PMID- 27709031 TI - Arthroscopic Femoral Osteochondroplasty for Cam-Type Femoroacetabular Impingement: The Trough Technique. AB - Arthroscopic osteochondroplasty has become the most common treatment for cam-type femoroacetabular impingement. However, gauging the appropriate depth and location of the femoral osteochondroplasty remains challenging, given the parallax observed from using a 70 degrees arthroscope across multiple viewing perspectives. Consequently, reliable techniques must use a combination of arthroscopic and fluoroscopic checks and balances to assess the femoral head-neck junction to help guide bony resection. We have developed a technique for osteochondroplasty that has made the process more efficient and reliable in our hands. It involves creating a trough at the apex of the osteochondroplasty and then contouring the proximal and distal regions to re-create normal proximal femoral geometry. This article details our technique for femoral osteochondroplasty, which can be performed alone for isolated cam impingement or in concert with other intra- and extra-articular procedures to address associated hip pathology. PMID- 27709032 TI - Extensor Tendoscopy of the Wrist. AB - Extensor tenosynovitis of the wrist can lead to rupture of the extensor tendons. Extensor tenosynovectomy is indicated if the tenosynovitis cannot be controlled by conservative measures. Open tenosynovectomy requires extensive dissection of soft tissue, including the extensor retinaculum. This article describes extensor tendoscopy of the wrist. This technique allows approach to the extensor compartments with small incisions and minimal soft tissue dissection. It is indicated when extensor tenosynovitis persists despite adequate medical treatments including medications, immobilization, and steroid injection. Synovectomy of the extensor compartments can be performed with preservation of the extensor retinaculum. This technique is contraindicated if the wrist cannot be flexed or there is severe tendinopathy of the extensor tendon that may need open reconstruction. The purpose of this technical note was to describe a minimally invasive approach of complete synovectomy of the extensor compartments with preservation of the extensor compartment. PMID- 27709034 TI - Posterior Horn of Medial Meniscal Peripheral Capsular Lesion: The Arthroscopic Repair Technique Working in the Posterior Compartment. AB - A posterior horn of medial meniscal peripheral capsular is usually associated with the anterior cruciate ligament injury. The conventional repair technique with the camera in the anterolateral portal cannot precisely restore the slope capsular synovium to the original attachment point. We present the arthroscopic technique for improving the accuracy and quality of the repair by working in the posterior compartment. When the posterolateral portal is used as the viewing portal, the accuracy of repair is improved because we can assess the full extent of the lesion and lift the sagging peripheral tissue to the more central part. PMID- 27709033 TI - Surgical Adjustment of the Guide Pin to Perform a Correct Tibial Tunnel in Anatomical Anterior Cruciate Ligament Single-Bundle Reconstruction. AB - Anatomical positioning of the graft in anterior cruciate ligament reconstruction is important to restore normal knee kinematics and prevent early joint degeneration. Inadequate position of a first attempt to place the guide pin within the center of the tibial footprint may occur. Therefore, its adjustment is important to achieve the anatomical positioning of the graft within the tibial footprint. When the guide pin exits eccentrically in an inadequate position, it is possible to correct it to the center of the footprint. A small tunnel with a 4.5-mm reamer is made and the guide pin is shifted to the center of the footprint. The center of the tunnel can be corrected until 50% and in all direction in relation to the initial drilled tunnel, without additional associated morbidity. Once the correct position of the center is achieved, the guide pin is fixed in the femoral notch roof to guarantee the accurate correction of the axis, without toggling of the guide pin inside the tunnel and metal dusting. The final tunnel is then drilled with the same size of the graft. With this technique it is possible to adjust an eccentrically misplaced guide pin to the center of the footprint without additional morbidity. PMID- 27709035 TI - Opening-Wedge Proximal Tibial Osteotomy. AB - Varus knee malalignment caused by medial compartment arthritis results in progressive asymmetric wear of the tibiofemoral joint. This wear can cause progressively painful gonarthrosis. Surgical methods to address varus knee malalignment include lateral closing-wedge proximal tibial osteotomy, medial opening-wedge osteotomy, and arthroplasty. Medial opening-wedge proximal tibial osteotomy is an effective procedure for restoring proper coronal alignment and reducing knee pain. In this technical note, we present a reproducible technique for proximal tibial osteotomy. PMID- 27709036 TI - Modified Arthroscopic Brostrom Procedure With Bone Tunnels. AB - The open anatomic repair of the anterior talofibular and calcaneofibular ligaments (modified Brostrom procedure) is widely accepted as the standard surgical stabilization procedure for lateral ankle instability that does not respond to conservative measures. Arthroscopic Brostrom procedures with a suture anchor have been reported to achieve both anatomic repair of the lateral ankle ligaments and management of the associated intra-articular lesions. However, the complication rates are higher than open Brostom procedures. Many of these complications are associated with the use of a suture anchor. We report a modified arthroscopic Brostrom procedure in which the anterolateral ankle capsule is anchored to the lateral malleolus through small bone tunnels instead of suture anchors. PMID- 27709037 TI - Outside-In Deep Medial Collateral Ligament Release During Arthroscopic Medial Meniscus Surgery. AB - Arthroscopic partial medial meniscectomy is a very common orthopaedic procedure performed for symptomatic, irreparable meniscus tears. It is usually associated with a very good outcome and minimal complications. In some patients with tight medial compartment, the posterior horn of the medial meniscus can be difficult to visualize, and access in this area with instruments may be challenging. To increase the opening of the medial compartment, after valgus-extension stress position of the knee, different techniques of deep medial collateral ligament release have been described. The outside-in pie-crusting technique shown in this technical note has documented effectiveness and good outcomes with minimal or no morbidity. PMID- 27709038 TI - Bicruciate Knee Ligament Reconstruction Using 4 All-Anterior Arthroscopic Portals. AB - The use of an accessory posteromedial portal for posterior cruciate ligament reconstruction in bicruciate knee ligament reconstruction has often been described. However, the use of a posteromedial portal can be time consuming and has some inherent risks including injury to the saphenous vein or nerve. We describe our bicruciate knee ligament reconstruction using 4 exclusively anterior portals including a high anteromedial, high anterolateral, low anteromedial, and low anterolateral portals. Arthroscopy is performed using a combination of 30 degrees and 70 degrees arthroscopes. Fluoroscopic assistance is used in conjunction with a 70 degrees arthroscope for the creation of the posterior cruciate ligament tibial tunnel. PMID- 27709039 TI - Inside-Out Repair for Radial Meniscus Tears. AB - Understanding of meniscal function through basic science, natural history, and biomechanics has highlighted the importance of preserving the meniscus to maintain normal knee biomechanics. Tears that may alter these biomechanics can contribute to the progressive nature of degenerative joint disease in the knee. Radial tears result in the disruption of the circumferential fibers causing inability of the native meniscus to resist normal hoop stresses, thereby leading to increased focal areas of pressure that cause complications such as early onset arthrosis. In this technical note, we describe our preferred operative technique to repair radial meniscal tears using an arthroscopic inside-out approach with satisfactory clinical outcomes and healing response. PMID- 27709040 TI - Varus-Producing Lateral Distal Femoral Opening-Wedge Osteotomy. AB - Valgus knee alignment in excess of physiological valgus leads to excessive loading of the lateral compartment, which can potentially increase the risk of osteoarthritis and can place the medial knee structures at risk of chronic attenuation. Varus-producing distal femoral osteotomies have been proposed for correction of valgus malalignment, to relieve tension on medial-sided structures, as well as to off-load the lateral compartment. Understanding that symptomatic valgus deformity of the knee represents a complex problem that is magnified in the setting of lateral compartment arthritis or medial ligamentous incompetence, we present our preferred technique for a varus-producing distal femoral osteotomy using plate osteosynthesis and cancellous bone allograft. PMID- 27709041 TI - Anatomic Anterior Cruciate Ligament Reconstruction: The Use of the Anterior Horn of the Lateral Meniscus as a Guide to Tibial Tunnel Placement. AB - Anatomic anterior cruciate ligament reconstruction has been shown to reduce the risk of graft failure and to improve patient-related clinical outcomes. The posterior border of the anterior horn of the lateral meniscus is a useful marker for anatomic tibial tunnel placement. Assessment of a preoperative magnetic resonance imaging scan can allow surgical planning of tibial tunnel placement to allow for anatomic, patient-specific tibial tunnel placement during anatomic anterior cruciate ligament reconstruction. We present this technique to show how to use the posterior border of the anterior horn of the lateral meniscus clinically. PMID- 27709042 TI - Simplified Setup to Achieve Distraction for Toe Arthroscopy. AB - Toe arthroscopy has historically had limited applications but is beginning to emerge as a viable treatment option for select toe pathologies, and continues to have expanding indications as technology and techniques improve. Toe arthroscopy has used a multitude of distraction techniques to perform the procedures but all have had limited success. Thus, we propose a simple toe arthroscopy distraction technique that uses an external positioning arm to allow the surgeon to apply manual traction in multiple positions without the use of an assistant, external weights, or any reprocessed sterile equipment. PMID- 27709043 TI - Endoscopic Gluteus Medius Repair Augmented With Bioinductive Implant. AB - Patients with gluteus minimus and medius tears that fail nonoperative management may be indicated for surgical repair; however, structural failure after gluteal tendon repair remains unacceptably high. This is likely related to the limited healing potential of tendinous tissue, which is poorly vascular and heals by formation of fibrocartilaginous scar tissue rather than histologically normal tendon. An emerging option to augment tendon healing is the use of a bioinductive implant that is designed to amplify the host healing response and induce the formation of healthy tendon tissue. Though it is rapidly being adopted for partial- and full-thickness rotator cuff tears, this implant has not yet been used in the hip. A detailed technical description and a discussion of the advantages and disadvantages of the technique are provided. PMID- 27709044 TI - Anterior Cruciate Ligament Reconstruction With Bone-Patellar Tendon-Bone Autograft and a Medial Parapatellar Portal. AB - Anterior cruciate ligament (ACL) reconstruction is one of the most extensively studied surgical procedures in orthopaedics. The importance of this ligament for knee function and stability has been widely studied. For athletes who participate in activities involving cutting, twisting, and running, surgical reconstruction of the ACL has become the standard of care. However, there is much debate regarding the techniques involved in ACL reconstruction, including graft choice, technique of drilling the femoral tunnel, and single- versus double-bundle reconstruction. In recent studies, ACL femoral tunnel drilling via a medial parapatellar or accessory anteromedial portal provides a more anatomic graft placement than transtibial femoral drilling. Long-term outcomes of these techniques have not been widely studied. This article details our technique for ACL reconstruction with bone-patellar tendon-bone autograft and a medial parapatellar portal. PMID- 27709045 TI - Arthroscopic Rotator Cuff Repair With Concomitant Capsular Release. AB - Patients with rotator cuff tears may present with or subsequently develop concomitant shoulder stiffness. The treatment of rotator cuff tears in the face of passive glenohumeral motion loss is controversial. Preoperative shoulder stiffness has been considered by some a contraindication to rotator cuff repair. Some surgeons recommend staging surgical procedures and delaying rotator cuff repair until shoulder stiffness has resolved. However, this can lead to prolonged recovery times and patient dissatisfaction. We describe a surgical technique that allows for the single-stage arthroscopic management of rotator cuff tears with associated adhesive capsulitis. Arthroscopic capsular release and shoulder manipulation are performed in the same operative setting as arthroscopic rotator cuff repair. We have found that this combined, single-stage arthroscopic approach can effectively treat patients with rotator cuff tears and concomitant shoulder stiffness. PMID- 27709046 TI - Arthroscopic Double-Row Suture Anchor Repair of Acute Posterior Bony Bankart Lesion. AB - The treatment of anterior shoulder instability is well described with various techniques, including arthroscopic double-row repair, an alternative to open stabilization procedures in high-risk groups. The surgical management of posterior instability in high-risk and athletic populations is a less-explored entity. We describe our technique for an all arthroscopic double-row suture anchor repair of a large posterior bony Bankart lesion. We prefer this technique over percutaneous cannulated screw fixation because the double-row suture technique allows for incorporation of capsular plication with bony fixation in an effort to better restore normal anatomy for capsulolabral complex. Double-row repair capsulolabral repair or fixation of the bony Bankart is performed via a suture-bridge technique. Medial row anchors are placed down the glenoid neck and shuttled around the bony fragment and labrum. The lateral-row anchor is placed at the rim of the native glenoid. This repair technique has been shown to increase the surface area for healing and more closely reconstruct the native anatomic capsulolabral complex footprint, improve force distribution, and potentially impart enhanced posterior stability to the glenohumeral joint. PMID- 27709047 TI - Valgus Extension Overload: Arthroscopic Decompression in the Supine-Suspended Position. AB - Elbow arthroscopy is a useful tool for managing diseases of the elbow, including valgus extension overload, when conservative treatments have failed. Arthroscopic access to the elbow in the supine-suspended position is simple and reproducible with the technique described in this report. Synovial tissue can be cleared, optimizing visualization of the anatomic structures in the elbow including the posterior ulnohumeral joint. This report describes, in detail, arthroscopy of the elbow in the supine-suspended position and basic principles for arthroscopic decompression of the posterior elbow for valgus extension overload. PMID- 27709048 TI - Ultrasound-Guided Portal Placement for Hip Arthroscopy. AB - Over the past 2 decades, hip arthroscopy has developed as a surgical technique, with more orthopaedic surgeons attempting to become proficient in performing this surgical procedure as indications and surgical skills evolve. The hip joint presents unique arthroscopic challenges because of its anatomic location, and it can be challenging to safely and confidently establish portal sites. Ultrasound guided hip arthroscopy portal placement is not yet common practice for orthopaedic surgeons. The potential advantages of ultrasound-guided hip arthroscopy portal placement are the lack of radiation exposure to the patient and operating room personnel, direct visualization of the hip joint and surrounding soft-tissue structures, and lack of bulky fluoroscopic equipment in the operative field. We describe a detailed technique incorporating video examples using ultrasound guidance to establish appropriate portal sites for hip arthroscopy with the aim to improve safety and overall operator competence. PMID- 27709049 TI - The Sliding, Interlocking "8-2-Alpha Knot" for Arthroscopic Surgery. AB - We describe a sliding knot that is ideally lockable by transforming the original simple figure-of-8 configuration into a true interlocking, low-profile knot with an alpha-alpha configuration that creates strong primary knot security when tying is finished. Reversed half-hitches on alternating posts for secondary knot security can be added, but to save surgical time, these are not obligatory. Three simple knot-tying methods are presented; the choice of which to use is based on the surgeon's preference. Pulling the loop limb simultaneously on both sides of the knot could trigger premature knot flipping. Therefore, the loop limb should not be over-tensioned while sliding down the knot; the knot should always be "pulled" down, rather than "pushed" down, onto the target tissues. Because all loops would be disassembled after the post limb is removed from the knot, a salvage procedure is proposed to save the suture from unintentional premature locking. PMID- 27709050 TI - Arthroscopic Repair of Posterior Glenohumeral Capsular Rupture With Concomitant Anterior and Posterior Labrum Detachment. AB - Posterior glenohumeral capsular rupture is a rare cause of posterior glenohumeral instability. With advances in imaging and arthroscopic techniques, diagnosis and treatment of posterior glenohumeral instability are becoming more common in practice. We present a technique for arthroscopic repair of a posterior glenohumeral capsular rupture with concomitant anterior and posterior labrum detachment. Arthroscopic fixation was facilitated by use of a 70 degrees arthroscope through an anterior viewing portal to allow accurate placement of the posterior portal in preparation for knot tying. This arthroscopic technique resulted in a successful outcome. PMID- 27709051 TI - Classification and Surgical Repair of Ramp Lesions of the Medial Meniscus. AB - Ramp lesions of the medial meniscus are commonly associated with anterior cruciate ligament ruptures and consist of longitudinal peripheral tears of the posterior horn of the medial meniscus. Given the frequency of partial-thickness tears, they can be difficult to diagnose arthroscopically from the anterior compartment. We describe a classification of the different types of ramp lesions depending on both tear pattern (partial- or full-thickness tear) and associated meniscotibial ligament disruption. An original technique of arthroscopic suture placement through a single posteromedial portal with a 25 degrees curved suture hook device is described. PMID- 27709052 TI - The Hidden Lesion of the Subscapularis: Arthroscopically Revisited. AB - The "hidden lesion" refers to a tear of the subscapularis in the presence of an intact biceps pulley or rotator interval. Visualization of these tears during open surgery is difficult, yet even with the advancement of arthroscopy, visualization can still be challenging. Incomplete visualization of the subscapularis could lead to failure to diagnose a tear of the tendon and subsequently hinder results after shoulder surgery. With the advancement of arthroscopy, a technique to identify these hidden lesions is needed to avoid inferior results. We describe an arthroscopic technique to visualize, diagnosis, and repair these tears when clinically indicated. Implementing this technique in the setting of suspected subscapularis tendon injury can provide complete visualization of the tendon insertion. PMID- 27709053 TI - Capsular Preservation Using Suture Suspension Technique in Hip Arthroscopy for Femoroacetabular Impingement. AB - This article describes the use of sutures to enhance visualization while protecting the capsule in both the central and peripheral compartments during hip arthroscopy. We describe first a technique to preserve the proximal capsule cuff while working in the central compartment and then an alternative to the T capsulotomy while maintaining excellent visualization of the peripheral compartment during femoroplasty of cam-type femoroacetabular impingement. By use of suture suspension of the capsule, multiple goals are achieved: The integrity of the proximal capsule cuff is maintained while aiding in visualization of the central compartment; the iliofemoral ligament is spared, which plays a critical role in preventing microinstability; the necessary space is created to obtain adequate visualization of the peripheral compartment for complete femoroplasty; and operative time is reduced because creation and subsequent repair of the T capsulotomy can be avoided. PMID- 27709054 TI - Medial Meniscus Radial Tear: A Transtibial 2-Tunnel Technique. AB - Complete radial tears of the medial meniscus significantly decrease the meniscal tissue's ability to dissipate tibiofemoral loads and have been described as functionally similar to a total meniscectomy, predisposing patients to early osteoarthritis. At present, no consensus exists regarding the optimal surgical treatment of a radial meniscal tear. Current repair techniques have led to a reportedly high rate of incomplete healing or healing of the meniscus in a nonanatomic, gapped position, which compromises its ability to withstand hoop stresses. Improvement regarding the ability to repair and heal medial meniscus radial tears has the potential to result in enhanced preservation of the articular cartilage in the medial compartment of the knee. This technical description details a method for repairing radial tears of the medial meniscus using a transtibial 2-tunnel technique.

AB - Advanced hip joint-preserving arthroscopic techniques have been shown to improve patient-reported functional outcomes with low rates of postoperative complications. Prior work has shown that formation of adhesive scar is a potential source of persistent pain and cause for revision surgery. As resources for postoperative in-studio physical therapy become scarce, a home-based strategy to avoid scar formation without adding formal therapy cost may be beneficial. The purpose of this technical note is to introduce a patient-centered educational video technique for home-caregiver delivery of manual hip pendulum exercises in the postoperative setting. This video technique offers access to our method for pendulum exercise as part of early recovery after advanced hip arthroscopy. PMID- 27709056 TI - Primary Repair of Tibial-Sided Avulsion of the Anterior Cruciate Ligament. AB - Lesions of the anterior cruciate ligament (ACL) are common; the current gold standard of treatment for such lesions is ACL reconstruction. Tibial-sided soft tissue avulsion is a rare subtype of ACL injuries. Unlike femoral-sided ACL repair, surgery for acute tibial-sided ACL ruptures has been neither reported nor described. This technical note presents a method for primary anatomic ACL reinsertion for an acute distal soft-tissue avulsion-type ACL injury, using a transosseous pull-out repair technique. Our technique, as an alternative to reconstruction, has the potential to enhance healing due to marrow stimulation (tibial tunneling). It also preserves the native insertion site and proprioceptive function, which may, in turn, reduce the risk of post-traumatic osteoarthritis. PMID- 27709057 TI - Arthroscopic Iliac Crest Bone Grafting to the Anterior Glenoid. AB - Failed arthroscopic soft-tissue stabilization and anterior glenoid bone loss have been shown to have high failure rates after standard arthroscopic stabilization techniques. For patients with recurrent glenohumeral instability, the Bristow Latarjet procedure is currently the standard of care. It is predominantly performed through an open deltopectoral approach but has recently been described arthroscopically. Although providing excellent clinical outcomes, the Bristow Latarjet procedure violates the subscapularis muscle, has a steep learning curve with a high complication rate, and permanently changes the anterior shoulder anatomy, making any future revision surgery more challenging. We describe a technique for arthroscopic anterior glenoid augmentation using iliac crest bone graft that does not violate the subscapularis, by creating a far anterior-medial portal that traverses superior to the subscapularis and lateral to the conjoint tendon. The graft is passed through this portal and secured with rigid fixation. An arthroscopic Bankart capsulolabral repair is then performed, making the graft extra-articular. A remplissage can easily be added as indicated, allowing this procedure to arthroscopically address all 3 major components of structural instability: glenoid bone loss, capsulolabral tearing, and humeral bone loss. PMID- 27709058 TI - Dry Arthroscopic Single-Stage Cartilage Repair of the Knee Using a Hyaluronic Acid-Based Scaffold With Activated Bone Marrow-Derived Mesenchymal Stem Cells. AB - Cartilage lesions of the knee are a frequent finding; however, treatment options that are capable of restoring hyaline-like tissue are not routinely used. Cell based technology such as autologous chondrocyte implantation may in some cases provide durable cartilage repair, but availability of this procedure is often restricted due to cost constraints. There have been promising outcomes reported with the use of scaffolds seeded with activated bone marrow aspirate concentrate in cases of chondral injury. There are clear advantages to cell-based cartilage repair techniques that are performed as a single-stage procedure, particularly when the repair technology can be used in a minimally invasive manner. We present an arthroscopic technique of cartilage repair using a hyaluronic acid-based scaffold associated with activated bone marrow aspirate concentrate. This technique is a cost-effective, minimally invasive, single-stage procedure that has the potential for routine use in a wide range of cartilage lesion types and locations. PMID- 27709059 TI - Medial Opening Wedge Proximal Tibial Osteotomy. AB - Genu varus malalignment can lead to medial compartment overload and progression of ipsilateral compartment osteoarthritis. To slow this process, a medial opening wedge proximal tibial osteotomy (PTO) can be performed. This type of PTO is indicated in patients with genu varus malalignment and isolated medial compartment osteoarthritis of the knee, prior to or concurrent with medial compartment cartilage procedures or meniscal transplants, chronic posterolateral corner deficiency, or chronic anterior cruciate ligament deficiency. When treating ligamentous instability, a PTO can be performed in isolation, with simultaneous ligament reconstruction, or as a staged procedure with the osteotomy first, followed by ligament reconstruction if instability persists. Failure to address malalignment in cases of concurrent ligament reconstruction leads to increased stress on the graft and potential graft failure. One distinct advantage of this procedure is the ability to correct deformities in the sagittal and coronal planes. The purpose of this article was to describe our technique used to perform a medial opening wedge PTO. PMID- 27709060 TI - Arthroscopic Juvenile Allograft Cartilage Implantation for Cartilage Lesions of the Hip. AB - Cartilage lesions in the hip are of high prevalence. Most of these lesions are treated with microfracture. Microfracture has relatively good subjective outcomes for smaller lesions; however, it is limited by the ability to reproduce hyaline cartilage, especially in older patients. For larger chondral defects, we present a technique using juvenile allograft cartilage implantation implanted arthroscopically to treat cartilage lesions in the hip. The purpose of this technical note is to describe the arthroscopic technique for treating chondral lesions in the hip with allograft juvenile cartilage. PMID- 27709061 TI - Arthroscopic "Panorama" View of the Subacromial Space via Deltoid Fascia Release. AB - Proper visualization is of paramount importance during arthroscopic rotator cuff repair. We propose a technique that significantly improves the visualization of the rotator cuff when viewing from the anterolateral or lateral portals. This "panorama" view is obtained by a release of the deep layer of the deltoid fascia, which in turn increases the space between the humerus and the deltoid muscle. This release increases the volume of the subdeltoid bursa, secondarily increasing the field of view of the subacromial space with the camera viewing from the anterolateral or lateral portals. This technical note describes a new technique useful in obtaining an excellent view of the subacromial space proving very useful in both the diagnosis and treatment of rotator cuff pathology. PMID- 27709062 TI - Arthroscopic Distal Triceps Repair. AB - In this note, we describe an arthroscopic repair of a degenerative tear of the triceps using a suture weave and an anatomic footprint anchor. We are able to assess, debride, and anatomically repair the distal triceps to its insertion. Compared with open procedures, this arthroscopic repair offers lower morbidity, faster recovery, and improved cosmesis. Our goal was to improve the function and strength of the elbow through this arthroscopic surgical fixation. PMID- 27709063 TI - Assessment and Evaluation of Glenoid Bone Loss. AB - The preoperative assessment of anterior glenoid bone loss is a critical step in surgical planning for patients with recurrent anterior glenohumeral instability. The structural integrity of the glenoid has been identified as one of the most important factors influencing the success of operative repair. The currently accepted gold standard for glenoid structural assessment among most orthopaedic surgeons is the use of 3-dimensional reconstructed computed tomography images with the humeral head digitally subtracted, yielding an en face sagittal oblique view of the glenoid. This view allows for evaluation of glenoid morphology and quantitative assessment of glenoid bone loss. In this article, we describe the practical application of ImageJ software (National Institutes of Health, Bethesda, MD) to quantify the amount of glenoid bone loss reported as a percentage of either total surface area or diameter. The following equations are used in this technical note for the diameter-based method and surface area method, respectively: Percent bone loss = (Defect width/Diameter of inferior glenoid circle) * 100% and Percent bone loss = (Defect surface area/Surface area of inferior glenoid circle) * 100%. PMID- 27709064 TI - Loffler syndrome on a Louisiana pig farm. AB - Loffler syndrome, a fulminant eosinophilic pneumonitis associated with the larval migratory phase of human parasites, is rarely reported in the United States. A previously healthy 8-year-old male was hospitalized with tachypnea, cough, hypoxemia, and fever of one week's duration. History revealed exposure to pigs on his family's farm in southernmost Louisiana, where the patient was responsible for cleaning the farm's pigpens. His fingernails were soiled and extremely short, with the edge of the nail bed exposed secondary to onychophagia. Laboratory evaluation demonstrated peripheral eosinophilia (39%), pulmonary eosinophilia (86%), high total IgE, diffuse reticulonodular lung opacities, and mixed obstructive and restrictive pulmonary function pattern. Systemic corticosteroids were initiated for his acute respiratory insufficiency and produced rapid clinical improvement. Serum Ascaris-specific IgE was markedly elevated and he was treated with albendazole. An extensive evaluation for other infectious and allergic etiologies was negative. A site visit to the family farm and laboratory investigation was coordinated with the Louisiana Animal Disease Diagnostic Laboratory at LSU. Ascaris suum eggs were detected in fresh pig feces and in the soil immediately surrounding the pens. Ascariasis should be considered even in the absence of travel history, especially in swine raising areas that are endemic for Ascaris in pigs, such as the southeastern United States. Onychophagia is a highly probable mechanism of zoonotic fecal-oral transmission in this case, and such habits could lead to continual reinfection. Systemic corticosteroids were effective in treating the patient's acute respiratory compromise due to Loffler syndrome. PMID- 27709068 TI - Bquant - Novel script for batch quantification of LCMS data. AB - Quantitative target analysis by liquid chromatography coupled to mass spectrometry (LCMS) is ubiquitous in environmental, metabolomic and toxicological studies. Targeted LCMS methods are capable of the simultaneous determination of literally hundreds of analytes. Although acquiring of instrumental data is very fast, data post-processing i.e. quantification can be time consuming step (and)or dependent to various commercial software packages. In attempt to facilitate this drawback Wolfram Mathematica script for batch quantification of LCMS data was created. Script works with direct outputs of integration algorithms created by different instrument control software's or custom created outputs. Key benefits of Bquant script are: *simple and automated routine for batch mode quantification*vast improvement in processing time (especially compared to manual interpretation)*data can be quickly re-analysed using different inputs Script was validated on various datasets and some of these were provided as working examples. PMID- 27709065 TI - Low putamen activity associated with poor reward sensitivity in childhood chronic fatigue syndrome. AB - Motivational signals influence a wide variety of cognitive processes and components of behavioral performance. Cognitive dysfunction in patients with childhood chronic fatigue syndrome (CCFS) may be closely associated with a low motivation to learn induced by impaired neural reward processing. However, the extent to which reward processing is impaired in CCFS patients is unclear. The aim of the present functional magnetic resonance imaging (fMRI) study was to determine whether brain activity in regions related to reward sensitivity is impaired in CCFS patients. fMRI data were collected from 13 CCFS patients (mean age, 13.6 +/- 1.0 years) and 13 healthy children and adolescents (HCA) (mean age, 13.7 +/- 1.3 years) performing a monetary reward task. Neural activity in high- and low-monetary-reward conditions was compared between CCFS and HCA groups. Severity of fatigue and the reward obtained from learning in daily life were evaluated by questionnaires. Activity of the putamen was lower in the CCFS group than in the HCA group in the low-reward condition, but not in the high-reward condition. Activity of the putamen in the low-reward condition in CCFS patients was negatively and positively correlated with severity of fatigue and the reward from learning in daily life, respectively. We previously revealed that motivation to learn was correlated with striatal activity, particularly the neural activity in the putamen. This suggests that in CCFS patients low putamen activity, associated with altered dopaminergic function, decreases reward sensitivity and lowers motivation to learn. PMID- 27709067 TI - Helminth community structure in two species of arctic-breeding waterfowl. AB - Climate change is occurring rapidly at high latitudes, and subsequent changes in parasite communities may have implications for hosts including wildlife and humans. Waterfowl, in particular, harbor numerous parasites and may facilitate parasite movement across broad geographic areas due to migratory movements. However, little is known about helminth community structure of waterfowl at northern latitudes. We investigated the helminth communities of two avian herbivores that breed at high latitudes, Pacific black brant (Branta bernicla nigricans), and greater white-fronted geese (Anser albifrons), to examine effects of species, geographic area, age, and sex on helminth species richness, aggregation, prevalence, and intensity. We collected 83 and 58 black brant and white-fronted geese, respectively, from Arctic and Subarctic Alaska July-August 2014. We identified 10 known helminth species (Amidostomum anseris, Amidostomum spatulatum, Drepanidotaenia lanceolata, Epomidiostomum crami, Heterakis dispar, Notocotylus attenuatus, Tetrameres striata, Trichostrongylus tenuis, Tschertkovilepis setigera, and Wardoides nyrocae) and 1 previously undescribed trematode. All geese sampled were infected with at least one helminth species. All helminth species identified were present in both age classes and species, providing evidence of transmission at high latitudes and suggesting broad host susceptibility. Also, all but one helminth species were present at both sites, suggesting conditions are suitable for transmission across a large latitudinal/environmental gradient. Our study provides important baseline information on avian parasites that can be used to evaluate the effects of a changing climate on host-parasite distributions. PMID- 27709069 TI - 7th Union Europe Conference on Lung Health, 22-24 June 2016, Bratislava (Slovakia): a delegate report. PMID- 27709066 TI - Brain volume loss contributes to arousal and empathy dysregulation following severe traumatic brain injury. AB - Severe traumatic brain injury (TBI) often leads to deficits in physiological arousal and empathy, which are thought to be linked. This study examined whether injury-related brain volume loss in key limbic system structures is associated with these deficits. Twenty-four adults with TBI and 24 matched Controls underwent MRI scans to establish grey matter volumes in the amygdala, thalamus, and hippocampus. EEG and skin conductance levels were recorded to index basal physiological arousal. Self-report emotional empathy levels were also assessed. The TBI group had reduced brain volumes, topographic alpha differences, and lower emotional empathy compared to Controls. Regional brain volumes were differentially correlated to arousal and self-report empathy. Importantly, lower volume in pertinent brain structures correlated with lower empathy, for participants with and without TBI. Overall we provide new insights into empathic processes after TBI and their relationship to brain volume loss. PMID- 27709070 TI - Endovascular stent placement for chronic post-thrombotic symptomatic ilio-femoral venous obstructive lesions: a single-center study of safety, efficacy and quality of-life improvement. AB - BACKGROUND: Post-thrombotic syndrome (PTS) is a frequent complication of deep vein thrombosis (DVT) despite adequate treatment. Venous angioplasty and stent placement has been progressively used to restore and maintain venous patency in PTS patients. This study reports our single-center experience with the use of endovascular treatment for chronic post-thrombotic symptomatic ilio-femoral venous obstructive lesions. METHODS: A prospective mono-centric observational cohort study of PTS patients with chronic symptomatic ilio-femoral venous obstructive lesions referred for endovascular treatment was conducted from March 2012 to April 2016. Procedure consisted in recanalization, pre-dilation and self expandable stenting of stenotic or occluded iliac and/or femoral veins. Severity of PTS, quality-of-life and treatment outcomes were assessed using Villalta scale and Chronic Venous Insufficiency Questionnaire (CIVIQ-20) at baseline and 3 months after the procedure. Imaging follow-up was based on duplex ultrasound (US) and computed tomography (CT). RESULTS: Twenty-one patients (11 females, 10 males; median age, 41 years; range, 32-60) were included. Recanalization and stenting was successfully accomplished in all prime procedures, 4 patients benefitted from an additional procedure. Immediate technical success rate was 96% considering 25 procedures, performed without any complications. Median follow-up was 18 months (range, 6-30 months) with a 90.5% stent patency rate. Villalta score significantly decreased from baseline compared with 3 months after the procedure [14 (range, 11-22) and 5 (range, 1-10), respectively, P<0.0001], showing a significant decrease in the severity of PTS. CIVIQ-20 score significantly decreased from baseline compared with 3 months after stenting [48.5 (range, 39 73) and 26.5 (range, 21-45), respectively, P<0.0001] thus showing a significant improvement of quality-of-life. Post-procedural CIVIQ-20 score was significantly associated with Villalta score (95% CI, 1.53-2.95; P<0.0001). CONCLUSIONS: Our results confirm the high clinical success rate and safety of endovascular PTS treatment and highlight the significant impact of stenting on the quality of life of patients with chronic symptomatic ilio-femoral venous obstructive lesions. PMID- 27709071 TI - Black blood T1rho MR imaging may diagnose early stage liver fibrosis: a proof-of principle study with rat biliary duct ligation model. AB - BACKGROUND: To explore black blood T1rho (T1rho) liver imaging and investigate the earliest stage when biliary duct ligation (BDL) induced liver fibrosis can be diagnosed. METHODS: MR was performed at 3 Tesla. A T1rho prepared 2D fast spin echo (FSE) sequence with acquisition of four spin lock times (TSLs: 1, 10, 30, and 50 msec) and spin-lock frequency of 500 Hz was applied. Inherent black blood effect of FSE and double inversion recovery (DIR) achieved blood signal suppression, and 3 axial sections per liver were obtained. Male Sprague-Dawley rats were scanned at baseline (n=32), and on day-3 (n=13), day-5 (n=11), day-7 (n=10), day-10 (n=4) respectively after BDL. Hematoxylin-eosin (HE) and picrosirius red staining liver histology was obtained at these time points. RESULTS: The physiological liver parenchyma T1rho was 38.38+/-1.53 msec (range, 36.05-41.53 msec). Liver T1rho value elevated progressively after BDL. On day-10 after BDL all experimental animals can be separated from normal liver based on T1rho measurement with lowest value being 42.82 msec. Day-7 and day-10 liver resembled METAVIR stage-F1/F2 fibrosis, and fibrous area counted for 0.22%+/ 0.13% and 0.38%+/-0.44% of liver parenchyma area, respectively. CONCLUSIONS: This study provides the first proof-of-principle that T1rho might diagnose early stage liver fibrosis. PMID- 27709072 TI - Hirayama's disease: an Italian single center experience and review of the literature. AB - BACKGROUND: Hirayama's disease (HD), is a benign, self-limited, motor neuron disease, characterized by asymmetric weakness and atrophy of one or both distal upper extremities. In the present study we report the clinical, electrophysiological and MRI features of a group of Italian patients, with review of the literature. Moreover we propose an optimized MRI protocol for patients with suspected or diagnosed HD in order to make an early diagnosis and a standardized follow up. METHODS: Eight patients with clinical suspicion of Hirayama disease underwent evaluation between January 2007 and November 2013. All patients underwent standard nerve conduction studies (NCS), electromyography (EMG) and motor/sensory evoked potentials (MEP/SEP). Cervical spine MRI studies were conducted with a 1.5 Tesla MRI scanner in neutral and flexion position, including sagittal T1-weighted sequences and sagittal and axial T2-weighted sequences. The following diagnostic features were evaluated: abnormal cervical curvature, localized cervical cord atrophy in the lower tract (C4-C7), presence of cord flattening (CF), intramedullary signal hyperintensity on T2 weighted sequences, anterior shifting of the posterior wall of the cervical dural sac (ASD) and presence of flow voids (EFV) in the posterior epidural space during flexion. RESULTS: All patients complained of weakness in hand muscles as initial symptoms, associated with hand tremor in three of them and abnormal sweating of the hand palm in two of them. No sensory deficits and weakness at lower limbs were reported by any patients. Distal deep tendon reflexes at upper limbs were absent in all patients with the absence of the right tricipital reflex in one of them. Deep tendon reflexes at lower limbs were normal and no signs of pyramidal tract involvement were present. The clinical involvement at onset was unilateral in six patients (three left-sided and three right-sided) and bilateral asymmetric in two of them, with the right side more affected. With the progression of the disease all patients but one experienced weakness and wasting of hand muscles and forearm bilaterally, but still asymmetric. The duration of the progression phase of the disease ranged from eight months to three years. In all patients, NCS and EMG findings were consistent with a spinal metameric disorder involving the C7-T1 myotomes bilaterally; sensory conduction and electrophysiologic features at lower limbs were normal. MEP and SEP were normal and we did not observe the disappearance of the spinal potential during the neck flexion in any of the patients. MRI is the best diagnostic tool in the diagnosis of HD; it can confirm clinical diagnosis and exclude other conditions responsible for the neurological deficits leading to a correct patient management and therapy, limiting arm impairment. On MRI all patients had loss of the normal cervical lordosis (100%). Five patients had loss of attachment of posterior dural sac and anterior dural shift on flexion MRI with presence of flow voids from venous plexus congestion (62.5%); three patients had no anterior dislocation of the dural sac and no epidural vein congestion. Two patients showed localized cord atrophy, one at C5 C6 and the other at C6-C7 level (25%). Three patients had T2 intramedullary hyperintensities (37.5%) and cord flattening (CF) was present in 5 patients of 8 (62.5%). CONCLUSIONS: HD is a rare entity and a self-limited condition, but it has to be early differentiated from other diseases that may determine myelopathy and amyotrophy to establish a correct therapy and limit arm impairment. MRI is very important to confirm the clinical suspect of HD and a standardized MRI protocol using axial and sagittal images in both neutral and flexing position is needed, in order to diagnose and follow up affected patients. PMID- 27709073 TI - Effects of magnetic field strength and b value on the sensitivity and specificity of quantitative breast diffusion-weighted MRI. AB - BACKGROUND: To evaluate the effect of b value or the magnetic field strength (B0) on the sensitivity and specificity of quantitative breast diffusion-weighted imaging (DWI). METHODS: A total of 126 patients underwent clinical breast MRI that included pre-contrast DWI imaging using b values of both 1,000 and 1,500 s/mm2 at either 1.5 T (n=86) or 3.0 T (n=40). Quantitative apparent diffusion coefficients (ADC) were measured and compared for 18 benign, 33 malignant lesions, and 126 normal breast tissues. Optimal ADCmean threshold for differentiating benign and malignant lesions was estimated and the effect of b values and B0 were examined using a generalized estimating equations (GEE) model. RESULTS: The optimal ADCmean threshold was 1.235*10-3 mm2/s for b value of 1,000 and 0.934*10-3 mm2/s for b value of 1,500. Using these thresholds, the sensitivities and specificities were 96% and 89% (b value =1,000, B0 =1.5 T), 89% and 98% (b value =1,000, B0 =3.0 T), 88% and 96% (b value =1,500, B0 =1.5 T), and 67% and 100% (b value =1,500, B0 =3.0 T). No significant difference was found between different B0 (P=0.26) or b values (P=0.28). CONCLUSIONS: Better sensitivity is achieved with DWI of b value =1,000 than with b value =1,500. However, b value and B0 do not significantly impact diagnostic performance of DWI when using appropriate thresholds. PMID- 27709074 TI - Correlation of delta high-resolution computed tomography (HRCT) score with delta clinical variables in early systemic sclerosis (SSc) patients. AB - BACKGROUND: The correlation of changes (delta: Delta) of high-resolution computed tomography (HRCT) score with the Delta of other clinical variables has not been well studied. The purpose of this study was to determine the correlation of Delta HRCT score with Delta percent predicted forced vital capacity (%pFVC), Delta modified Rodnan Skin Score (mRSS), Delta erythrocyte sedimentation rate (ESR), and Delta percent of oxygen saturation at room air (%SpO2) in patients with early systemic sclerosis (SSc). METHODS: We used an inception cohort of early-SSc patients seen at the Rheumatology Clinic, Chiang Mai University, Thailand, between January 2010 and June 2014. All patients underwent HRCT at study entry and every 12 months thereafter. Thirty-one SSc patients who underwent pulmonary function test (PFT) within 12 weeks of their corresponding HRCT at baseline and last visit were identified. The extent of ground glass (GG), lung fibrosis (Fib), bronchiectasis (B), and honeycombing (HC) was scored, and then aggregated to produce a total (t) HRCT score. RESULTS: Mean +/- SD age and disease duration from non-Raynaud's phenomenon (NRP) to undergo HRCT at baseline were 52.2+/-8.8 years and 11.7+/-7.1 months, respectively. Seventeen (54.8%) patients were female and 20 (64.5%) were classified as dcSSc. The mean +/- SD interval between the two HRCT tests was 16.0+/-7.2 months. The Delta HRCT scores [total fibrosis scores (t Fib), total bronchiectasis scores (t-B), and total HRCT score (t-HRCT) scores] and Delta mRSS, but not Delta %pFVC, showed significant change over the observation period. We found significant correlation of Delta total honeycombing scores (t-HC) with Delta ESR (r=-0.44, P<0.05), and Delta t-Fib with Delta %SpO2 (r=-0.38, P<0.05). However, no significant correlation of any Delta HRCT scores with Delta %pFVC and Delta mRSS were observed. CONCLUSIONS: In this study, the changes in the HRCT scores were greater than %pFVC; this, along with their correlations with the changes in ESR and %SpO2, suggest that HRCT scores are a useful and sensitive method for monitoring disease progression in early SSc related ILD (SSc-ILD). PMID- 27709075 TI - Automated registration and enhanced processing of clinical optical coherence tomography angiography. AB - BACKGROUND: Motion artifacts degrade the quality of optical coherence tomography angiography (OCTA). Orthogonal registration can eliminate the majority of these artifacts, but some artifacts persist in most clinical images. We evaluate an automated registration algorithm with selective merging and filtering to remove remaining artifacts and improve the quality of images. METHODS: A 70 kHz commercial spectral domain OCT was used to obtain 3 mm * 3 mm OCTA in 10 healthy, 5 age-related macular degeneration (AMD), and 31 diabetic retinopathy (DR) participants. Projection artifacts were removed and images were segmented into 3 inner retinal plexuses. Amplitude thresholding identified lines containing a residual artifact and correlation between neighboring lines identified distorted stripes. Then the angiograms were registered and the lines selectively merged. A vesselness filter was applied to the resulting images. The images were evaluated for signal-to-noise ratio (SNR), image entropy, vessel connectivity and vessel density. RESULTS: Registration and selective merging (RSM) algorithm improved the SNR (P<0.02) compared to orthogonal registration alone. RSM with vesselness filter increased the image entropy (P<10-8) and reduced inter-subject variability (standard error <=3%, n=10) in healthy eyes. The method improved vessel details and connectivity in OCTA of healthy, DR and neovascular AMD eyes. CONCLUSIONS: This automated registration method eliminates residual motion artifacts and enhances the visualization of vessels in OCTA. PMID- 27709076 TI - Lumbar intervertebral discs T2 relaxometry and T1rho relaxometry correlation with age in asymptomatic young adults. AB - BACKGROUND: To investigate the detection of intervertebral disc (IVD) composition aging-related changes using T2 and T1rho relaxometry in vivo in asymptomatic young adults. METHODS: We recruited ninety asymptomatic and young adults (42 men and 48 women) between 20 and 40 years old. T2 and T1rho lumbar spine mappings were acquired using 1.5 T magnetic resonance imaging (MRI) scanner. Two independent observers manually segmented 450 lumbar discs in all slices. They also performed sub region segmentation of annulus fibrosus (AF) and nucleus pulposus (NP) at the central MRI sagittal slices. RESULTS: There was no difference between men and women for T2 (P=0.37) or T1rho relaxometry (P=0.97). There was a negative correlation between age (20-40 years) and IVD T2 relaxation time of the whole disc (r=-0.30, P<0.0001), NP (r=-0.20 to -0.51, P<0.05) and posterior AF (r=-0.21 to -0.31, P<0.05) at all lumbar disc levels. There was no statistical correlation between aging and IVD T1rho relaxation both for NP and AF. CONCLUSIONS: T2 relaxometry detected gradual IVD dehydration in the first two decades of adulthood. We observed no significant variation of T1rho or volumetry with aging in our study group. Our results suggest that T2 mapping may be more appropriate to detect early IVD aging changes. PMID- 27709077 TI - Correlation between pneumonitis risk in radiation oncology and lung density measured with X-ray computed tomography. AB - BACKGROUND: The risk of toxicity with radiation oncology for lung cancer limits the maximal radiation dose that can be delivered to thoracic tumors. This study aims at investigating the correlation between normal tissue complication probability (NTCP) and physical lung density by analyzing the computed tomography (CT) scan imaging used for radiotherapy dose planning. METHODS: Data from CT of lung cancer patients (n=10), treated with three dimensional radiotherapy, were selected for this study. The dose was calculated using analytical anisotropic algorithm (AAA). Dose volume histograms (DVH) for healthy lung (lung excluding targets) were calculated. The NTCP for lung radiation induced pneumonitis was computed using initial radiobiological parameters from Lyman-Kutcher and Burman (LKB) model and readjusted parameters for AAA, with alpha/beta=3. The correlation coefficient "rho" was calculated using Spearman's rank test. The bootstrap method was used to estimate the 95% confidence interval (95% CI). Wilcoxon paired test was used to calculate P values. RESULTS: Bootstrapping simulation revealed significant difference between NTCP computed with the initial radiobiological parameters and that computed with the parameters readjusted for AAA (P=0.03). The results of simulations based on 1,000 replications showed no correlation for NTCP with density, with "rho" <0.3. CONCLUSIONS: For a given set of patients, we assessed the correlation between NTCP and lung density using bootstrap analysis. The lack of correlation could result either from a very accurate dose calculation, by AAA, whatever the lung density yielding a NTCP result only dependant of the dose and not any more of the density; or to the very limited range of natural variation of relative electronic density (0.15 to 0.20) observed in this small series of patients. Another important parameter is the bootstrap simulation with 1,000 random samplings may have underestimated the correlation, since the initial data (n=10) showed a weak correlation. PMID- 27709078 TI - Statistical assessment of bi-exponential diffusion weighted imaging signal characteristics induced by intravoxel incoherent motion in malignant breast tumors. AB - BACKGROUND: The purpose of this study is to statistically assess whether bi exponential intravoxel incoherent motion (IVIM) model better characterizes diffusion weighted imaging (DWI) signal of malignant breast tumor than mono exponential Gaussian diffusion model. METHODS: 3 T DWI data of 29 malignant breast tumors were retrospectively included. Linear least-square mono-exponential fitting and segmented least-square bi-exponential fitting were used for apparent diffusion coefficient (ADC) and IVIM parameter quantification, respectively. F test and Akaike Information Criterion (AIC) were used to statistically assess the preference of mono-exponential and bi-exponential model using region-of-interests (ROI)-averaged and voxel-wise analysis. RESULTS: For ROI-averaged analysis, 15 tumors were significantly better fitted by bi-exponential function and 14 tumors exhibited mono-exponential behavior. The calculated ADC, D (true diffusion coefficient) and f (pseudo-diffusion fraction) showed no significant differences between mono-exponential and bi-exponential preferable tumors. Voxel-wise analysis revealed that 27 tumors contained more voxels exhibiting mono exponential DWI decay while only 2 tumors presented more bi-exponential decay voxels. ADC was consistently and significantly larger than D for both ROI averaged and voxel-wise analysis. CONCLUSIONS: Although the presence of IVIM effect in malignant breast tumors could be suggested, statistical assessment shows that bi-exponential fitting does not necessarily better represent the DWI signal decay in breast cancer under clinically typical acquisition protocol and signal-to-noise ratio (SNR). Our study indicates the importance to statistically examine the breast cancer DWI signal characteristics in practice.

PMID- 27709079 TI - Functional magnetic resonance imaging techniques and their development for radiation therapy planning and monitoring in the head and neck cancers. AB - Radiation therapy (RT), in particular intensity-modulated radiation therapy (IMRT), is becoming a more important nonsurgical treatment strategy in head and neck cancer (HNC). The further development of IMRT imposes more critical requirements on clinical imaging, and these requirements cannot be fully fulfilled by the existing radiotherapeutic imaging workhorse of X-ray based imaging methods. Magnetic resonance imaging (MRI) has increasingly gained more interests from radiation oncology community and holds great potential for RT applications, mainly due to its non-ionizing radiation nature and superior soft tissue image contrast. Beyond anatomical imaging, MRI provides a variety of functional imaging techniques to investigate the functionality and metabolism of living tissue. The major purpose of this paper is to give a concise and timely review of some advanced functional MRI techniques that may potentially benefit conformal, tailored and adaptive RT in the HNC. The basic principle of each functional MRI technique is briefly introduced and their use in RT of HNC is described. Limitation and future development of these functional MRI techniques for HNC radiotherapeutic applications are discussed. More rigorous studies are warranted to translate the hypotheses into credible evidences in order to establish the role of functional MRI in the clinical practice of head and neck radiation oncology.

PMID- 27709093 TI - How to set-up a program of minimally-invasive surgery for congenital heart defects. AB - BACKGROUND: Mid-line sternotomy is the commonest incision for cardiac surgery. Alternative approaches are becoming fashionable in many centres, amidst some reluctance because of learning curves and overall complexity. Our recent experience in starting a new program on minimally invasive pediatric cardiac surgery is presented. The rationale for a stepwise onset and the short-medium term results for a three-year span are displayed. METHODS: A three-step schedule is planned: First, an experienced surgeon (A) starts performing simple cases. Second, new surgeons (B, C, D, E) are introduced to the minimally invasive techniques according to their own proficiency and skills. Third, the new adopters are enhanced to suggest and develop further minimally invasive approaches. Two quality markers are defined: conversion rate and complications. RESULTS: In part one, surgeon A performs sub-mammary, axillary and lower mini-sternotomy approaches for simple cardiac defects. In part two, surgeons B, C, D and E are customly introduced to such incisions. In part three, new approaches such as upper mini-sternotomy, postero-lateral thoracotomy and video-assisted mini thoracotomy are introduced after being suggested and developed by surgeons B, C and E, as well as an algorithm to match cardiac conditions and age/weight to a given alternative approach. The conversion rate is one out of 148 patients. Two major complications were recorded, none of them related to our alternative approach. Four minor complications linked to the new incision were registered. The minimally invasive to mid-line sternotomy ratio rose from 20% in the first year to 40% in the third year. CONCLUSIONS: Minimally invasive pediatric cardiac surgery is becoming a common procedure worldwide. Our schedule to set up a program proves beneficial. The three-step approach has been successful in our experience, allowing a tailored training for every new surgeon and enhancing the enthusiasm in developing further strategies on their own. Recording conversion rates and complications stands for quality standards. A twofold increase in minimally invasive procedures was observed in two years. The short-medium term results after three years are excellent. PMID- 27709092 TI - Antegrade cerebral perfusion at 25 degrees C for arch reconstruction in newborns and children preserves perioperative cerebral oxygenation and serum creatinine. AB - BACKGROUND: Antegrade cerebral perfusion (ACP) typically is used with deep hypothermia for cerebral protection during aortic arch reconstructions. The impact of ACP on cerebral oxygenation and serum creatinine at a more tepid 25 degrees C was studied in newborns and children. METHODS: Between 2010 and 2014, 61 newborns and children (<5 years old) underwent aortic arch reconstruction using moderate hypothermia (25.0+/-0.9 degrees C) with ACP and a pH-stat blood gas management strategy. These included 44% Norwood-type operations, 30% isolated arch reconstructions, and 26% arch reconstructions with other major procedures. Median patient age at surgery was 9 days (range, 3 days-4.7 years). Cerebral oxygenation (NIRS) was monitored continuously perioperatively for 120 hours. Serum creatinine was monitored daily. RESULTS: Median cardiopulmonary bypass (CPB) and cross clamp times were 181 minutes (range, 82-652 minutes) and 72 minutes (range, 10-364 minutes), respectively. ACP was performed at a mean flow rate of 46+/-6 mL/min/kg for a median of 48 minutes (range, 10-123 minutes). Cerebral and somatic NIRS were preserved intraoperatively and remained at baseline postoperatively during the first 120 hours. Peak postoperative serum creatinine levels averaged 0.7+/-0.3 mg/dL for all patients. There were 4 (6.6%) discharge mortalities. Six patients (9.8%) required ECMO support. Median postoperative length of hospital and intensive care unit (ICU) stay were 16 days(range, 4-104 days) and 9 days (range, 1-104 days), respectively. Two patients (3.3%) received short-term peritoneal dialysis for fluid removal, and none required hemodialysis. Three patients (4.9%) had an isolated seizure which resolved with medical therapy, and none had a neurologic deficit or stroke. CONCLUSIONS: ACP at 25 degrees C preserved perioperative cerebral oxygenation and serum creatinine for newborns and children undergoing arch reconstruction. Early outcomes are encouraging, and additional study is warranted to assess the impact on late outcomes. PMID- 27709094 TI - Goal-directed-perfusion in neonatal aortic arch surgery. AB - Reduction of mortality and morbidity in congenital cardiac surgery has always been and remains a major target for the complete team involved. As operative techniques are more and more standardized and refined, surgical risk and associated complication rates have constantly been reduced to an acceptable level but are both still present. Aortic arch surgery in neonates seems to be of particular interest, because perfusion techniques differ widely among institutions and an ideal form of a so called "total body perfusion (TBP)" is somewhat difficult to achieve. Thus concepts of deep hypothermic circulatory arrest (DHCA), regional cerebral perfusion (RCP/with cardioplegic cardiac arrest or on the perfused beating heart) and TBP exist in parallel and all carry an individual risk for organ damage related to perfusion management, chosen core temperature and time on bypass. Patient safety relies more and more on adequate end organ perfusion on cardiopulmonary bypass, especially sensitive organs like the brain, heart, kidney, liver and the gut, whereby on adequate tissue protection, temperature management and oxygen delivery should be visualized and monitored.

AB - Since the first successful intervention for hypoplastic left heart syndrome (HLHS) was undertaken by Norwood in 1983, there have been many advancements in the pre-, intra-, and postoperative care of these children for a diagnosis that just 25 years ago was almost certainly a fatal one. This paper aims to describe the most recent trends and perspectives on the treatment of HLHS. In particular, we will discuss the five current options for HLHS, including Norwood stage I as the beginning to 3-stage palliation, transplant, true hybrid, hybrid-bridge-to Norwood, and compassionate care. PMID- 27709097 TI - Critical cardiac care in children: looking backward and looking forward. AB - The growth of Pediatric Cardiovascular Intensive Care as a subspecialty has been incredible. Outcomes have improved, care delivery has matured, and research has made advances. Within this review, we take the opportunity to examine the subspecialty's past accomplishments with pride, take stock in its current state, and look forward with excitement to its future. While outcomes in general have improved dramatically, we must always be aware of the outcomes that matter to families and patients. Additionally, we must constantly ask ourselves to improve. Research into neuroprotection and individual therapeutic strategies based in genomic medicine provide the next opportunity for the subspecialty to improve. PMID- 27709096 TI - Prophylactic arrhythmia surgery in association with congenital heart disease. AB - Certain congenital heart anomalies make patients more susceptible to arrhythmia development throughout their lives. This poses the question whether prophylactic arrhythmia surgery should be incorporated into reparative open heart procedures for congenital heart disease. There is currently no consensus on what constitutes a standard prophylactic procedure, owing to the questions that remain regarding lesions to be performed; energy sources to use; proximity of energy source or incisions to coronary arteries, sinoatrial node, atrioventricular node; circumstances for right atrial, left atrial, or biatrial appendectomy; and whether to perform a right, left, or biatrial maze procedure. These considerations are important because prophylactic arrhythmia procedures are performed without knowing if the patient will actually develop an arrhythmia in his or her lifetime. By reviewing and summarizing the literature, congenital heart disease patients who are at risk for developing atrial arrhythmias can be identified and lesion sets can be suggested in an effort to standardize experimental protocols for prophylactic arrhythmia surgery.

The utilization of the reverse Szabo (anchor-wire) technique for single collateral vessel stenting in a case of PA-VSD is described. PMID- 27709099 TI - Preoperative evaluation and surgical decision-making in pediatric epilepsy surgery. AB - Epilepsy is a common disease in the pediatric population, and the majority of cases are controlled with medications and lifestyle modification. For the children whose seizures are pharmacoresistant, continued epileptic activity can have a severely detrimental impact on cognitive development. Early referral of children with drug-resistant seizures to a pediatric epilepsy surgery center for evaluation is critical to achieving optimal patient outcomes. There are several components to a thorough presurgical evaluation, including a detailed medical history and physical examination, noninvasive testing including electroencephalogram, magnetic resonance imaging (MRI) of the brain, and often metabolic imaging. When necessary, invasive diagnostic testing using intracranial monitoring can be used. The identification of an epileptic focus may allow resection or disconnection from normal brain structures, with the ultimate goal of complete seizure remission. Additional operative measures can decrease seizure frequency and/or intensity if a clear epileptic focus cannot be identified. In this review, we will discuss the nuances of presurgical evaluation and decision making in the management of children with drug-resistant epilepsy (DRE).

PMID- 27709103 TI - The Tip of the Iceberg: On the Roles of Regulatory Small RNAs in the Virulence of Enterohemorrhagic and Enteropathogenic Escherichia coli. AB - Enterohemorrhagic and enteropathogenic Escherichia coli are gastrointestinal pathogens that disrupt the intestinal microvilli to form attaching and effacing (A/E) lesions on infected cells and cause diarrhea. This pathomorphological trait is encoded within the pathogenicity island locus of enterocyte effacement (LEE). The LEE houses a type 3 secretion system (T3SS), which upon assembly bridges the bacterial cytosol to that of the host and enables the bacterium to traffic dozens of effectors into the host where they hijack regulatory and signal transduction pathways and contribute to bacterial colonization and disease. Owing to the importance of the LEE to EHEC and EPEC pathogenesis, much of the research on these pathogens has centered on its regulation. To date, over 40 proteinaceous factors have been identified that control the LEE at various hierarchical levels of gene expression. In contrast, RNA-based regulatory mechanisms that converge on the LEE have only just begun to be unraveled. In this minireview, we highlight major breakthroughs in small RNAs (sRNAs)-dependent regulation of the LEE, with an emphasis on their mechanisms of action and/or LEE-encoded targets. PMID- 27709102 TI - Macrolide Resistance in Streptococcus pneumoniae. AB - Streptococcus pneumoniae is a common commensal and an opportunistic pathogen. Suspected pneumococcal upper respiratory infections and pneumonia are often treated with macrolide antibiotics. Macrolides are bacteriostatic antibiotics and inhibit protein synthesis by binding to the 50S ribosomal subunit. The widespread use of macrolides is associated with increased macrolide resistance in S. pneumoniae, and the treatment of pneumococcal infections with macrolides may be associated with clinical failures. In S. pneumoniae, macrolide resistance is due to ribosomal dimethylation by an enzyme encoded by erm(B), efflux by a two component efflux pump encoded by mef (E)/mel(msr(D)) and, less commonly, mutations of the ribosomal target site of macrolides. A wide array of genetic elements have emerged that facilitate macrolide resistance in S. pneumoniae; for example erm(B) is found on Tn917, while the mef (E)/mel operon is carried on the 5.4- or 5.5-kb Mega element. The macrolide resistance determinants, erm(B) and mef (E)/mel, are also found on large composite Tn916-like elements most notably Tn6002, Tn2009, and Tn2010. Introductions of 7-valent and 13-valent pneumococcal conjugate vaccines (PCV-7 and PCV-13) have decreased the incidence of macrolide resistant invasive pneumococcal disease, but serotype replacement and emergence of macrolide resistance remain an important concern. PMID- 27709104 TI - Positive Feedback Cycle of TNFalpha Promotes Staphylococcal Enterotoxin B-Induced THP-1 Cell Apoptosis. AB - Staphylococcal enterotoxin B (SEB) has been demonstrated to be of importance in Staphylococcus aureus related diseases, such as atopic dermatitis (AD). Dysregulated apoptosis in AD is remarkable, and SEB can induce apoptosis of various cell types. However, the mechanisms by which SEB induces apoptosis and influences disease processes remain unclear. In this study, the recombinant SEB induced THP-1 monocyte apoptosis was demonstrated in the absence of preliminary cell activation in a time- and dose-dependent manner. SEB could up-regulate the expression of tumor necrosis factor alpha (TNFalpha) in THP-1 cells and induce apoptosis via an extrinsic pathway. TNFalpha could in turn increase the expression of HLA-DRa, the SEB receptor on the cell surface. As a result, a positive feedback cycle of TNFalpha was established. TNFalpha expression and SEB induced apoptosis were decreased by knocking down the expression of either HLA DRa or TNFR1. Therefore, the feedback cycle of TNFalpha is crucial for SEB functions. This work provides insights into the mechanisms of SEB-induced monocyte apoptosis and emphasizes the major role of TNFalpha in future related studies. PMID- 27709106 TI - Nutritional knowledge, attitude and practice toward micronutrients among Iranian households: the NUTRI-KAP survey. AB - BACKGROUND: Healthy diet for maintaining a healthy weight and prevention of chronic disease is vital at all stages of life. The purpose of this study was to determine the nutritional knowledge, attitude, and practice among urban and rural households in Iran. METHODS: In this nation-wide study, 14,136 subjects were selected using a multistage cluster sampling method from 31 provinces of Iran. This study was on the households in rural and urban areas in Iran. Participants of this study were mothers or other members who were responsible for preparing meals for the whole family. Data were gathered by the questionnaire and the interview with the qualified person in each family. RESULTS: Frequency of knowledge about food source of calcium was between 11.6 and 64.7 %. Knowing of food source of zinc was about 12.8-16.7 %. Knowledge about of meat as source of iron was 50.9 and 46.5 % in regions of urban and rural, respectively. Positive attitude about preferring to use the full-fat dairy was about 25.1 % and negative attitude about this issue was 71.4 %; the positive attitude was slightly lower in rural areas than in urban areas. Respectively, frequency of using red meat in urban households was 10.8, 73.7, and 15.5 % as daily, weekly and rarely. Frequency of using daily of milk, yogurt and cheese was significantly lower in rural than in urban household. CONCLUSION: This national study indicates that in some cases there is a gap between knowledge and behavior among household of Iranian population. PMID- 27709105 TI - Differential association of plasma monocyte chemoattractant protein-1 with systemic inflammatory and airway remodeling biomarkers in type-2 diabetic patients with and without asthma. AB - BACKGROUND: Chronic inflammation is a hallmark of type-2 diabetes (T2D) and asthma. Monocyte chemoattractant protein (MCP)-1 or CCL-2 is a key regulator of monocytic infiltration into the sites of inflammation. The changes in systemic MCP-1 levels and its relationship with other inflammatory/immune markers in T2D patients with asthma remain unclear and have been addressed in this study. METHODS: Plasma samples from 10 asthmatic T2D patients (Group I: BMI = 37.82 +/- 9.75 kg/m2), 13 non-asthmatic T2D patients (Group II: BMI = 32.68 +/- 4.63 kg/m2), 23 asthma patients without T2D (Group III: BMI = 30.14 +/- 6.74 kg/m2), and 25 non-asthmatic non-diabetic controls (Group IV: BMI = 27.99 +/- 5.86 kg/m2) were used to measure levels of MCP-1 and multiple cytokine/chemokine biomarkers with bead-based multiplex assays using Luminex technology. IgE/ECP were measured using commercial ELISA kits. Data (mean +/- SEM) were compared using unpaired Student's t-test and linear dependence between two variables was assessed by Pearson's correlation coefficient (r) and P <= 0.05 was considered as significant. RESULTS: Plasma MCP-1 levels were significantly higher in Group I (337.95 +/- 46.40 pg/mL) as compared with Group II (216.69 +/- 17.30 pg/mL), Group III (251.76 +/- 19.80 pg/mL), and Group IV (223.52 +/- 133.36 pg/mL). MCP-1 showed differential association with tested biomarkers by correlating positively with: (i) IFN-alpha2, IL-10, fractalkine, and VEGF in T2D patients with asthma; (ii) IL-6 and GRO-alpha in T2D patients without asthma; (iii) MDC, IP-10, GM-CSF, FGF-2, and PDGF-AA/BB in patients with asthma only; and (iv) FPG and TG in non asthmatic non-diabetic controls. MCP-1 associated with IL-1RA only in subjects with asthma. CONCLUSION: The systemic MCP-1 levels were significantly elevated in T2D patients with asthma as compared with those without asthma and/or diabetes while these changes correlated differentially with important biomarkers of inflammation and airway remodeling. PMID- 27709107 TI - The Effect of Vascular Neuropathology on Late-life Cognition: Results from the SMART Project. AB - BACKGROUND: Cerebral vascular pathology may contribute to cognitive decline experienced by some elderly near death. Given evidence for mixed neuropathologies in advanced age, preventing or reducing cerebrovascular burden in late life may be beneficial. OBJECTIVE: To correlate measures of cerebral vascular pathology with cognitive trajectories. SETTING: Observational study. PARTICIPANTS: A cohort of 2,274 individuals who came to autopsy at a mean age of 89.3 years and 82 percent of whom had at least two cognitive assessments within the last six years of life was compiled from six centers conducting longitudinal studies. MEASUREMENTS: For each cognitive domain: immediate and delayed memory, language, and naming, three trajectories were examined: good, intermediate, and poor cognition. The probability of a participant belonging to each trajectory was associated with measures of cerebral vascular pathology after adjustment for demographics, APOE, and Alzheimer neuropathology. RESULTS: A large proportion of the cohort (72-94%) experienced good or intermediate cognition in the four domains examined. The presence of arteriolosclerosis and the presence of lacunar infarcts doubled the odds of belonging to the poor cognitive trajectory for language when compared to the good trajectory. The presence of lacunar infarcts increased the odds of an intermediate or poor trajectory for immediate and delayed recall while the presence of large artery infarcts increased the odds of poor trajectories for all four cognitive domains examined. Microinfarcts and cerebral amyloid angiopathy had little effect on the trajectories. CONCLUSION: Indicators of cerebral vascular pathology act differently on late life cognition. PMID- 27709109 TI - Defining Sudden Infant Death and Sudden Intrauterine Unexpected Death Syndromes with Regard to Anatomo-Pathological Examination. AB - Crib death, or sudden infant death syndrome (SIDS), is the most frequent form of death in the first year of life, striking one baby in every 1,700-2,000. Yet, despite advances in maternal-infant care, sudden intrauterine unexplained/unexpected death syndrome (SIUDS) has a sixfold to eightfold greater incidence than that of SIDS. Frequent congenital abnormalities, likely morphological substrates for SIDS-SIUDS, were detected, mainly represented by alterations of the cardiac conduction system, such as accessory pathways and abnormal resorptive degeneration, and hypoplasia/agenesis of the vital brainstem structures. On the basis of these considerations, the new common definition of the SIDS-SIUDS complex is "The sudden death of a fetus after the 25th gestational week or infant under one year of age which is unexpected by history and remains unexplained after a thorough case investigation, including examination of the death scene, performance of a general autopsy and examination of the fetal adnexa". Therefore, given that the general autopsy does not disclose any cause of death, a more in-depth histopathological analysis of the cardiac conduction system and autonomic nervous system by specialized pathologists is necessary. PMID- 27709108 TI - Familial and Clinical Correlates in Depressed Adolescents with Borderline Personality Disorder Traits. AB - INTRODUCTION: Chart review is a low-cost, but highly informative, method to describe symptoms, treatment, and risk factors associated with borderline personality disorder (BPD) and to adapt screening and intervention to clinical reality. Previous chart review studies report more aggressiveness/anger and psychotic features in youths with BPD. They show that adverse family environment and parental psychopathology constitute important factors for BPD pathology. OBJECTIVES: To examine clinical characteristics of depressed BPD adolescents (12 17 years old) outpatients according to gender and to explore variables which are associated with BPD traits. METHODS: A retrospective chart review using the child and adolescent version of the retrospective diagnostic instrument for borderlines was conducted on 30 depressed adolescents with BPD traits and 28 depressed patients without BPD traits. Participants who reached the retrospective diagnostic instrument for borderlines threshold for BPD were included in the BPD traits group. Comparison analyses were performed using Pearson's Chi-square test. Associated factors were determined using regression analyses. RESULTS: BPD traits participants were characterized by higher family problems (parental psychopathology, parent disagreement/argument, and parent-child relational problem), more aggressive symptoms, and higher rates of family intervention and hospitalization. A number of familial factors (parental history of delinquency, substance use, personality disorders, having siblings, or parental disagreement/argument in boys) were associated with BPD traits. Attention seeking and problematic functioning (does not adapt well to group activities) were also associated with BPD traits. DISCUSSION: Our study stresses the need to assess BPD traits in adolescent psychiatric evaluation, especially in the presence of aggressive behaviors, family problems and attention seeking. Our results also highlight the importance of exploring family characteristics intervention in adolescents with BPD traits. PMID- 27709110 TI - Why We Move: Social Mobility Behaviors of Non-Disabled and Disabled Children across Childcare Contexts. AB - BACKGROUND: Social mobility is defined as the co-occurrence of self-directed locomotion and direct peer interaction. Social mobility is a product of dynamic child-environment interactions and thus likely to vary across contexts (e.g., classroom, gymnasium, and playground). PURPOSE: The purpose of this present study was to examine differences in children's social mobility: (1) across contexts by age and (2) between non-disabled and disabled children. METHOD: Participants (n = 55 non-disabled and three disabled children; Mage = 3.1 years, SD = 1.4) were video recorded within a university-based early learning center. Children were recorded for 20 min in each context: classroom, gymnasium, and playground. A 15-s momentary time sampling method was used to code social mobility, the simultaneous occurrence of self-directed locomotion, and direct peer interaction. This variable was calculated as percent time within each context. RESULTS: A planned Friedman's rank ANOVA (n = 55), stratified by age, indicated that older children (3-5 years old) differed across contexts in their social mobility [chi2(2) ~ 7.3 10.5, p < 0.025], whereas younger children (1-2 years old) were similar across contexts. Social mobility was significantly lower in the classroom compared with the playground and gymnasium (with no difference between the latter contexts) for older children. Visual analysis confirmed that disabled children (n = 3) engaged in substantially less time in social mobility (average 0-1%), compared with non disabled, age-similar peers (2-3 years old average 1-12%) across all contexts. CONCLUSION: A substantial gap exists between non-disabled and disabled children for social mobility. There is an increase in magnitude and variability of social mobility around age three that suggests the gap between non-disabled and disabled children will continue to widen. PMID- 27709112 TI - Autocrine VEGF Isoforms Differentially Regulate Endothelial Cell Behavior. AB - Vascular endothelial growth factor A (VEGF) is involved in all the essential biology of endothelial cells, from proliferation to vessel function, by mediating intercellular interactions and monolayer integrity. It is expressed as three major alternative spliced variants. In mice, these are VEGF120, VEGF164, and VEGF188, each with different affinities for extracellular matrices and cell surfaces, depending on the inclusion of heparin-binding sites, encoded by exons 6 and 7. To determine the role of each VEGF isoform in endothelial homeostasis, we compared phenotypes of primary endothelial cells isolated from lungs of mice expressing single VEGF isoforms in normoxic and hypoxic conditions. The differential expression and distribution of VEGF isoforms affect endothelial cell functions, such as proliferation, adhesion, migration, and integrity, which are dependent on the stability of and affinity to VEGF receptor 2 (VEGFR2). We found a correlation between autocrine VEGF164 and VEGFR2 stability, which is also associated with increased expression of proteins involved in cell adhesion. Endothelial cells expressing only VEGF188, which localizes to extracellular matrices or cell surfaces, presented a mesenchymal morphology and weakened monolayer integrity. Cells expressing only VEGF120 lacked stable VEGFR2 and dysfunctional downstream processes, rendering the cells unviable. Endothelial cells expressing these different isoforms in isolation also had differing rates of apoptosis, proliferation, and signaling via nitric oxide (NO) synthesis. These data indicate that autocrine signaling of each VEGF isoform has unique functions on endothelial homeostasis and response to hypoxia, due to both distinct VEGF distribution and VEGFR2 stability, which appears to be, at least partly, affected by differential NO production. This study demonstrates that each autocrine VEGF isoform has a distinct effect on downstream functions, namely VEGFR2-regulated endothelial cell homeostasis in normoxia and hypoxia. PMID- 27709111 TI - Fluidic Logic Used in a Systems Approach to Enable Integrated Single-Cell Functional Analysis. AB - The study of single cells has evolved over the past several years to include expression and genomic analysis of an increasing number of single cells. Several studies have demonstrated wide spread variation and heterogeneity within cell populations of similar phenotype. While the characterization of these populations will likely set the foundation for our understanding of genomic- and expression based diversity, it will not be able to link the functional differences of a single cell to its underlying genomic structure and activity. Currently, it is difficult to perturb single cells in a controlled environment, monitor and measure the response due to perturbation, and link these response measurements to downstream genomic and transcriptomic analysis. In order to address this challenge, we developed a platform to integrate and miniaturize many of the experimental steps required to study single-cell function. The heart of this platform is an elastomer-based integrated fluidic circuit that uses fluidic logic to select and sequester specific single cells based on a phenotypic trait for downstream experimentation. Experiments with sequestered cells that have been performed include on-chip culture, exposure to various stimulants, and post exposure image-based response analysis, followed by preparation of the mRNA transcriptome for massively parallel sequencing analysis. The flexible system embodies experimental design and execution that enable routine functional studies of single cells.

PMID- 27709114 TI - Metal-Induced Stabilization and Activation of Plasmid Replication Initiator RepB. AB - Initiation of plasmid rolling circle replication (RCR) is catalyzed by a plasmid encoded Rep protein that performs a Tyr- and metal-dependent site-specific cleavage of one DNA strand within the double-strand origin (dso) of replication. The crystal structure of RepB, the initiator protein of the streptococcal plasmid pMV158, constitutes the first example of a Rep protein structure from RCR plasmids. It forms a toroidal homohexameric ring where each RepB protomer consists of two domains: the C-terminal domain involved in oligomerization and the N-terminal domain containing the DNA-binding and endonuclease activities. Binding of Mn2+ to the active site is essential for the catalytic activity of RepB. In this work, we have studied the effects of metal binding on the structure and thermostability of full-length hexameric RepB and each of its separate domains by using different biophysical approaches. The analysis of the temperature-induced changes in RepB shows that the first thermal transition, which occurs at a range of temperatures physiologically relevant for the pMV158 pneumococcal host, represents an irreversible conformational change that affects the secondary and tertiary structure of the protein, which becomes prone to self associate. This transition, which is also shown to result in loss of DNA binding capacity and catalytic activity of RepB, is confined to its N-terminal domain. Mn2+ protects the protein from undergoing this detrimental conformational change and the observed protection correlates well with the high-affinity binding of the cation to the active site, as substituting one of the metal-ligands at this site impairs both the protein affinity for Mn2+and the Mn2+-driven thermostabilization effect. The level of catalytic activity of the protein, especially in the case of full-length RepB, cannot be explained based only on the high-affinity binding of Mn2+ at the active site and suggests the existence of additional, lower-affinity metal binding site(s), missing in the separate catalytic domain, that must also be saturated for maximal activity. The molecular bases of the thermostabilizing effect of Mn2+ on the N-terminal domain of the protein as well as the potential location of additional metal binding sites in the entire RepB are discussed.

Current pharmacotherapy options include cytotoxic chemotherapy, anti-VEGF, and anti-EGFR targeting drugs, but these are limited by toxic side effects, limited responses and ultimately resistance. Cysteinyl leukotriene (CysLT) signaling regulates intestinal homeostasis with mounting evidence suggesting that CysLT signaling also plays a role in the pathogenesis of colorectal cancer. Therefore, CysLT signaling represents a novel target for this malignancy. This review evaluates reported links between CysLT signaling and established hallmarks of cancer in addition to its pharmacological potential as a new therapeutic target. PMID- 27709116 TI - Dynamic Simulation of the Effects of Graft Fixation Errors During Medial Patellofemoral Ligament Reconstruction. AB - BACKGROUND: Medial patellofemoral ligament (MPFL) reconstruction is performed to prevent recurrent instability, but errors in femoral fixation can elevate graft tension. HYPOTHESIS: Errors related to femoral fixation will overconstrain the patella and increase medial patellofemoral pressures. STUDY DESIGN: Controlled laboratory study. METHODS: Five knees with patellar instability were represented with computational models. Kinematics during knee extension were characterized from computational reconstruction of motion performed within a dynamic computed tomography (CT) scanner. Multibody dynamic simulation of knee extension, with discrete element analysis used to quantify contact pressures, was performed for the preoperative condition and after MPFL reconstruction. A standard femoral attachment and graft resting length were set for each knee. The resting length was decreased by 2 mm, and the femoral attachment was shifted 5 mm posteriorly. The simulated errors were also combined. Root-mean-square errors were quantified for the comparison of preoperative patellar lateral shift and tilt between computationally reconstructed motion and dynamic simulation. Simulation output was compared between the preoperative and MPFL reconstruction conditions with repeated-measures Friedman tests and Dunnett comparisons against a control, which was the standard MPFL condition, with statistical significance set at P < .05. RESULTS: Root-mean-square errors for simulated patellar tilt and shift were 5.8 degrees and 3.3 mm, respectively. Patellar lateral tracking for the preoperative condition was significantly larger near full extension compared with the standard MPFL reconstruction (mean differences of 8 mm and 13 degrees for shift and tilt, respectively, at 0 degrees ), and lateral tracking was significantly smaller for a posterior femoral attachment (mean differences of 3 mm and 4 degrees for shift and tilt, respectively, at 0 degrees ). The maximum medial pressure was also larger for the short graft with a posterior femoral attachment than for standard MPFL reconstruction, with a significant increase in the mean value of 1.6 MPa at 30 degrees . CONCLUSION: MPFL reconstruction reduces lateral tracking, but nonanatomic femoral fixation and overtensioning the graft overcorrect patellar tracking and increase pressure applied to medial patellar cartilage. CLINICAL RELEVANCE: Errors in femoral fixation and graft tensioning can lead to postoperative loss of flexion and overloading of medial cartilage.

PMID- 27709117 TI - Genetic and Clinical Predictors of Deep Brain Stimulation in Young-Onset Parkinson's Disease. AB - OBJECTIVE: In a cohort of patients with young-onset Parkinson's disease (PD), the authors assessed (1) the prevalence of genetic mutations in those who enrolled in deep brain stimulation (DBS) programs compared with those who did not enroll DBS programs and (2) specific genetic and clinical predictors of DBS enrollment. METHODS: Subjects were participants from 3 sites (Columbia University, Rush University, and the University of Pennsylvania) in the Consortium on Risk for Early Onset Parkinson's Disease (CORE-PD) who had an age at onset < 51 years. The analyses presented here focus on glucocerebrosidase (GBA), leucine-rich repeat kinase 2 (LRRK2), and parkin (PRKN) mutation carriers. Mutation carrier status, demographic data, and disease characteristics in individuals who did and did not enroll in DBS were analyzed. The association between mutation status and DBS placement was assessed in logistic regression models. RESULTS: Patients who had PD with either GBA, LRRK2, or PRKN mutations were more common in the DBS group (n = 99) compared with the non-DBS group (n = 684; 26.5% vs. 16.8%, respectively; P = 0.02). In a multivariate logistic regression model, GBA mutation status (odds ratio, 2.1; 95% confidence interval, 1.0-4.3; P = 0.05) was associated with DBS surgery enrollment. However, when dyskinesia was included in the multivariate logistic regression model, dyskinesia had a strong association with DBS placement (odds ratio, 3.8; 95% confidence interval, 1.9-7.3; P < 0.0001), whereas the association between GBA mutation status and DBS placement did not persist (P = 0.25). CONCLUSIONS: DBS populations are enriched with genetic mutation carriers. The effect of genetic mutation carriers on DBS outcomes warrants further exploration. PMID- 27709119 TI - Latina/o or Mexicana/o?: The Relationship between Socially Assigned Race and Experiences with Discrimination. AB - Discrimination based on one's racial or ethnic background is one of the oldest and most perverse practices in the United States. While much of this research has relied on self-reported racial categories, a growing body of research is attempting to measure race through socially-assigned race. Socially-assigned or ascribed race measures how individuals feel they are classified by other people. This paper draws on the socially assigned race literature and explores the impact of socially assigned race on experiences with discrimination using a 2011 nationally representative sample of Latina/os (n=1,200). While much of the current research on Latina/os has been focused on the aggregation across national origin group members, this paper marks a deviation by using socially-assigned race and national origin to understand how being ascribed as Mexican is associated with experiences of discrimination. We find evidence that being ascribed as Mexican increases the likelihood of experiencing discrimination relative to being ascribed as White or Latina/o. Furthermore, we find that being miss-classified as Mexican (ascribed as Mexican, but not of Mexican origin) is associated with a higher likelihood of experiencing discrimination compared to being ascribed as white, ascribed as Latina/o, and correctly ascribed as Mexican. We provide evidence that socially assigned race is a valuable complement to self identified race/ethnicity for scholars interested in assessing the impact of race/ethnicity on a wide range of outcomes. PMID- 27709121 TI - Wind tunnel and numerical data on the ventilation performance of windcatcher with wing wall. AB - The data presented in this article were the basis for the study reported in the research articles entitled "Evaluation of a two-sided windcatcher integrated with wing wall (as a new design) and comparison with a conventional windcatcher" (P. Nejat, J.K. Calautit, M.Z.A. Majid, B.R. Hughes, I. Zeynali, F. Jomehzadeh, 2016) [1] which presents the effect of wing wall on the air flow distribution under using the windcatchers as a natural ventilation equipment. Here, we detail the wind tunnel testing and numerical set-up used for obtaining the data on ventilation rates and indoor airflow distribution inside a test room with a two sided windcatcher and wing wall. Three models were integrated with wing wall angled at 30 degrees , 45 degrees and 60 degrees and another windcatcher was a conventional two-sided device. The computer-aided design (CAD) three-dimensional geometries which were produced using Solid Edge modeler are also included in the data article. PMID- 27709120 TI - MRI features in 17 patients with l2 hydroxyglutaric aciduria. AB - l-2-Hydroxyglutaric (l-2-HG) aciduria is a rare inherited metabolic disease usually observed in children. Patients present a very slowly progressive deterioration with cerebellar ataxia, mild or severe mental retardation, and various other clinical signs including extrapyramidal and pyramidal symptoms, and seizures Goffette et al. [1]. This leukencephalopathy was first described in 1980 Duran et al. [2]. Brain magnetic resonance imaging (MRI) demonstrates nonspecific subcortical white matter (WM) loss, cerebellar atrophy and changes in dentate nuclei and putamen Steenweg et al. [3]. The diagnosis is highlighted by increased levels of l-2-HG in body fluids such as urine and cerebrospinal fluid. The purpose of this study is to retrospectively describe the brain MRI features in l 2-HG aciduria.

PMID- 27709127 TI - Human induced pluripotent stem cell-derived cardiac tissue on a thin collagen membrane with natural microstructures. AB - Human induced pluripotent stem cells (hiPSCs) and appropriate scaffolds are of great interest in cardiac tissue engineering. In this work, we present a simple and new strategy to produce a thin collagen membrane with a natural microstructure from porcine tendons and reconstruct the functional cardiac tissues by recellularizing hiPSC-derived cardiomyocytes onto the membrane, for the first time. The collagen membrane maintained its intact properties after decellularization, the composition of which was identified as collagen I. The cardiomyocytes grown on the thin membrane strongly expressed the cardiac-specific marker cardiac troponin T and exhibited the specific morphology guided by the natural microstructure of the collagen fibers. The formed cardiac tissue could maintain a strong beating function spontaneously for over one month and respond rapidly to the two types of anti-arrhythmic drugs with opposed effects. The proposed approach is very simple, and easy to operate with a low cost. The obtained thin collagen membrane with a natural microstructure is analogous to the in vivo extracellular matrix structure and functions, supporting the good function of the engineered cardiac tissue. We envision that this work would open a new way for a wide range of applications in cardiac tissue engineering, drug testing and regenerative medicine. PMID- 27709128 TI - Fast and robust fabrication of reusable molds for hydrogel micro-patterning. AB - Mechanical interactions between cells and their microenvironment are crucial for fundamental biological processes ranging from migration to differentiation. This has led, over the last decades, to the development of new ways to culture cells. Living cells are now grown not only on glass coverslips, where they completely lose the mechanical and geometrical constraints coming from their microenvironment, but also on soft patterned substrates that mimic the rigidity and spatial information of their in vivo niches. Microfabrication processes have thus logically emerged has new tools to create model environments to probe the behavior of biological objects. Here, we present a method for fast and robust protein micropattern transfer onto polyacrylamide hydrogels that can be used for traction force microscopy. The technique relies on the elaboration of glass templates bearing patterned polymer brushes, which can be re-employed several times for the production of patterned gels without the need to repeat the critical microfabrication steps. PMID- 27709126 TI - Epitope Capsid-Incorporation: New Effective Approach for Vaccine Development for Chagas Disease. AB - BACKGROUND: Previously we reported that a hexon-modified adenovirus (Ad) vector containing the invasive neutralizing epitope of Trypanosoma cruzi (T. cruzi) trypomastigote gp83 (Ad5-gp83) provided immunoprotection against T. cruzi infection. The purpose of this work was to design an improved vaccine for T. cruzi using a novel epitope capsid incorporation strategy. Thus, we evaluated the immunoprotection raised by co-immunization with Ad5-gp83 and an Ad vector containing an epitope (ASP-M) of the T. cruzi amastigote surface protein 2. METHODS: Protein IX (pIX)-modified Ad vector (Ad5-pIX-ASP-M) was generated, characterized, and validated. C3H/He mice were immunized with Ad5-pIX-ASP-M and Ad5-gp83 and the cell-mediated responses were evaluated by enzyme-linked immunospot (ELISPOT) assay and intracellular staining. Immunized mice were challenged with T. cruzi to evaluate the vaccine efficacy. RESULTS: Our findings indicate that Ad5-pIX-ASP-M was viable. Specific CD8+ T-cell mediated responses prior to the challenge show an increase in IFNgamma and TNFalpha production. A single immunization with Ad5-pIX-ASP-M provided protection from T. cruzi infection, but co-immunizations with Ad5-pIX-ASP-M and Ad5-gp83 provided a higher immunoprotection and increased survival rate of mice. CONCLUSIONS: Overall, these results suggest that the combination of gp83 and ASP-M specific epitopes onto the capsid-incorporated adenoviruses would provide superior protection against Chagas disease as compared with Ad5-gp83 alone. PMID- 27709125 TI - Genetic and transcriptional analysis of human host response to healthy gut microbiota. AB - Many studies have demonstrated the importance of the gut microbiota in healthy and disease states. However, establishing the causality of host-microbiota interactions in humans is still challenging. Here, we describe a novel experimental system to define the transcriptional response induced by the microbiota in human cells and to shed light on the molecular mechanisms underlying host-gut microbiota interactions. In primary human colonic epithelial cells, we identified over 6,000 genes that change expression at various time points following co-culturing with the gut microbiota of a healthy individual. Among the differentially expressed genes we found a 1.8-fold enrichment of genes associated with diseases that have been previously linked to the microbiome, such as obesity and colorectal cancer. In addition, our experimental system allowed us to identify 87 host SNPs that show allele-specific expression in 69 genes. Furthermore, for 12 SNPs in 12 different genes, allele-specific expression is conditional on the exposure to the microbiota. Of these 12 genes, eight have been associated with diseases linked to the gut microbiota, specifically colorectal cancer, obesity and type 2 diabetes. Our study demonstrates a scalable approach to study host-gut microbiota interactions and can be used to identify putative mechanisms for the interplay between host genetics and microbiota in health and disease. PMID- 27709130 TI - Synthesis and characterization of biodegradable lysine-based waterborne polyurethane for soft tissue engineering applications. AB - Biomaterials for soft tissue engineering scaffolds require a combination of multiple properties including suitable mechanical properties, biodegradability, and biocompatibility. In this work, a series of light-crosslinking waterborne polyurethanes (LWPUs) were prepared using l-lysine ethyl ester diisocyanate (LDI), 1,3-propanediol (PDO) and l-lysine as hard segments and poly(epsilon caprolactone) (PCL) and poly(ethylene glycol) (PEG) as soft segments. The obtained LWPUs exhibited appropriate stretchability with a break elongation of 1400-2500% and an excellent strength of 12-18 MPa, which could admirably meet the requirements for soft tissue engineering scaffolds. In addition, the hydrophilic surfaces of LWPUs could effectively reduce protein adsorption and platelet adhesion and favor cell proliferation compared with traditional biomedical polyurethanes. The ultimate degradation products of LWPUs were proven to be nontoxic in a cytotoxicity test. More interestingly, a cytokine release test of macrophages adherent to the LWPU film surfaces shows that these macrophages secreted less pro-inflammation cytokine TNF-alpha and more anti-inflammation cytokine IL-10 after 3 days' culture, indicating that LWPUs possess the potential ability to aid in the transition of macrophages toward a wound healing phenotype. Furthermore, the LWPU films could support the adhesion and proliferation of endothelial cells. Thus, the obtained LWPUs have great potential for applications in soft tissue engineering scaffolds for tissue repair and wound healing. PMID- 27709129 TI - Cellular uptake of drug loaded spider silk particles. AB - Medical therapies are often accompanied by un-wanted side-effects or, even worse, targeted cells can develop drug resistance leading to an ineffective treatment. Therefore, drug delivery systems are under investigation to lower the risk thereof. Drug carriers should be biocompatible, biodegradable, nontoxic, non immunogenic, and should show controllable drug loading and release properties. Previous studies qualified spider silk particles as drug delivery carriers, however, cellular uptake was only tested with unloaded spider silk particles. Here, the effect of drug loading on cellular uptake of previously established spider silk-based particles made of eADF4(C16), eADF4(C16)RGD, eADF4(C16)R8G and eADF4(kappa16) was investigated. Fluorescently labelled polyethylenimine was used as a model substance for loading eADF4(C16), eADF4(C16)RGD or eADF4(C16)R8G particles, and fluorescently labelled ssDNA was used for loading eADF4(kappa16) particles. Upon loading polyanionic eADF4(C16) and eADF4(C16)RGD particles with polycationic polyethylenimine the cellular uptake efficiency was increased, while the uptake of eADF4(C16)R8G and polycationic eADF4(kappa16) particles was decreased upon substance loading. The latter could be circumvented by coating substance-loaded eADF4(kappa16) particles with an additional layer of eADF4(kappa16) (layer-by-layer coating). Further, it could be shown that eADF4(C16)RGD and eADF4(kappa16) uptake was based on clathrin-mediated endocytosis, whereas macropinocytosis was more important in case of eADF4(C16) and eADF4(C16)R8G particle uptake. Finally, it was confirmed that drugs, such as doxorubicin, can be efficiently delivered into and released within cells when spider silk particles were used as a carrier. PMID- 27709131 TI - Near infrared imaging-guided photodynamic therapy under an extremely low energy of light by galactose targeted amphiphilic polypeptide micelle encapsulating BODIPY-Br2. AB - Near infrared (NIR) imaging-guided photodynamic therapy (PDT) is attractive, especially the utilization of one dye as both a photosensitizer and fluorescent probe, and the as-synthesized BODIPY-Br2 molecule is a candidate. Here, a galactose targeted amphiphilic copolymer of a polypeptide was synthesized and its micelles work as nanocarriers for BODIPY for targeting the NIR imaging-guided PDT of hepatoma cancer cells. At the same time, BODIPY could light up the cytoplasm for real-time imaging and kill cancer cells when the light was switched on. In vitro tests performed on both HepG2 and HeLa cells confirmed that the as-prepared PMAGP-POEGMA-PLys-B micelles showed efficient cell suppression of the cells with galactose receptors in the presence of light under an extremely low energy density (6.5 J cm-2). This protocol highlights the potential of polypeptides as biodegradable carriers for NIR image-guided and confined targeting photodynamic therapy. PMID- 27709132 TI - Improved osteogenesis and angiogenesis of magnesium-doped calcium phosphate cement via macrophage immunomodulation. AB - Immune responses are vital for bone regeneration and play an essential role in the fate of biomaterials after implantation. As a kind of plastic cell, macrophages are central regulators of the immune response during the infection and wound healing process including osteogenesis and angiogenesis. Magnesium calcium phosphate cement (MCPC) has been reported as a promising candidate for bone repair with promoted osteogenesis both in vitro and in vivo. However, relatively little is known about the effects of MCPC on immune response and the following outcome. In this study, we investigated the interactions between macrophages and MCPC. Here we found that the pro-inflammatory cytokines including TNF-alpha and IL-6 were less expressed and the bone repair related cytokine of TGF-beta1 was up-regulated by macrophages in MCPC extract. Furthermore, the enhanced osteogenic capacity of BMSCs and angiogenic potential of HUVECs were acquired in vitro by the MCPC-induced immune microenvironment. These findings suggest that MCPC is able to facilitate bone healing by endowing favorable osteoimmunomodulatory properties and influencing crosstalk behavior between immune cells and osteogenesis-related cells. PMID- 27709133 TI - Rheological properties, biocompatibility and in vivo performance of new hydrogel based bone fillers. AB - Three different heterologous substitutes for bone regeneration, manufactured with equine-derived cortical powder (CP), cancellous chips (CC) and demineralized bone matrix granules (DBM), were compared in in vitro and in vivo settings. We tested: a commercially available bone paste (Osteoplant-ActivagenTM, consisting of aqueous collagenous carrier, CP, DBM; named A); a second-generation injectable paste (20 kDa polyethylene glycol/hydroxypropyl-methyl cellulose-based hydrogel, CP, DBM; B); a pre-formed bone filler (400 kDa polyethylene oxide/hydroxypropyl methyl cellulose-based hydrogel, CP, CC, DBM; C). Vitamin C acted as a visco modulator during C and B beta-rays sterilization, modifying graft injectability. For each filler, we examined dissolution in culture medium, gene expression of the substitute-exposed osteogenically-induced human bone marrow stromal cells (hBMSC), and performance in a rabbit bone defect model. A dissolved after 1 h, while fragmentation of B peaked after 8 h. C remained unaltered for 2 days, but affected the microenvironmental pH, slowing the proliferation of exposed cells. B exposed hBMSC overexpressed bone sialoprotein, osteocalcin and RUNX2. For all fillers histological results evidenced bridged lesion margins, marrow replenishment and bone-remodeling. However, B-treated lesions displayed a metachromatic type II collagen-rich matrix with prehypertrophic-like cells, matching the in vitro expression of cartilage-specific markers, and suggesting a possible application of B/C double-layer monolithic osteochondral plugs for full thickness articular defects. PMID- 27709134 TI - Polycaprolactone-chitosan nanofibers influence cell morphology to induce early osteogenic differentiation. AB - Osteogenic differentiation is highly correlated with cell morphology. Morphological changes are a stimulus as well as a consequence of the differentiation process. Besides, geometrical, biochemical and mechanical properties of a substrate can modulate cell adhesion and morphology. Therefore, in the current study, nanofibrous substrate properties were used to implement necessary changes in cell morphology which induced osteogenic differentiation without biological supplements. A polycaprolactone-chitosan nanofiber substrate had been fabricated with an average diameter of ~75 nm and an appropriate ratio of polymers that balances surface biocompatibility as well as mechanical strength. DSC and wide-angle XRD analysis revealed miscibility between polymers; whereas a degradation study confirmed the structural integrity of nanofibers. Nanofibers did not cause any cytotoxicity to MC3T3-E1 cells as confirmed by Live/Dead(r) staining. Morphological studies by SEM and confocal microscopy showed significant changes in terms of cell shape, area, compactness, aspect ratio and nucleus area in cells grown on nanofibers which indicated the osteogenic differentiation inducing potential of nanofibers. This was further confirmed by enhanced mineral deposition and alkaline phosphatase activity up to three weeks. In summary, polycaprolactone-chitosan nanofibers could induce early osteogenic differentiation in MC3T3-E1 pre-osteoblasts without any biological supplements by modulating cell morphology. Moreover, cell morphological features can be used as a predictive and informative approach at the early stages of differentiation experiments. PMID- 27709135 TI - Correcting the fundamental ion mobility equation for field effects. AB - The fundamental ion mobility equation computes the energy-averaged collision cross section as a function of measured drift velocity, electric field strength, ion and neutral masses, and drift gas state parameters. As field strength approaches zero, in particular when the drift velocity drops below about 4% of the average ion-neutral thermal speed, the fundamental equation takes on an especially simple form because the collision frequency and average momentum transfer become indistinguishable from their thermal values. However, in modern high-performance IMS-MS instruments, ion drift velocities may be 10-50% or more of thermal speed, and analysis using the zero-field equation gives rise to erroneously large cross sections. We address this problem by developing correction factors for the zero-field equation from an improved momentum-transfer (MT) theory for ion mobility, corrected and completed herein, and from the well known two-temperature (2T) theory. The corrected and uncorrected equations are compared by their ability to recover known hard-sphere cross sections from accurately-computed mobility data. Both MT and 2T expressions adjust for the field-driven increase in collision frequency and are noticeably superior to zero field expression whenever the ion drift velocity is greater than ~4% of thermal speed. The MT expression also adjusts for the mass and field dependent change in average momentum transfer, and is more accurate than the 2T first approximation whenever the mass of the ionic species is greater than about four times that of drift gas molecules, as is the case in most analytical applications of IMS coupled to MS. PMID- 27709136 TI - A thermoresponsive supramolecular copolymer hydrogel for the embolization of kidney arteries. AB - Our team has previously reported a high strength thermoplastic supramolecular polymer hydrogel. However, the hydrogel required injection temperatures outside the physiological range therefore preventing its use in a living environment. In this article, we reported a thermoresponsive supramolecular copolymer hydrogel p(N-acryloyl glycinamide-co-acrylamide) (PNAGA-PAAm), which can be injected at temperatures within the physiological range. We used rheological measurements to demonstrate that the transition temperature (upper critical solution temperature) of both the moduli and gel-sol could be finely adjusted by controlling both the ratio and concentration of the monomer. Adding iohexol (contrast agent) in PNAGA PAAm hydrogels contributed to the decreased moduli and gel-sol transition temperature due to weakening of the hydrogen bonding interactions. The cytocompatible and hemocompatible PNAGA-PAAm sol mixed with iohexol was injected into the renal arteries of rabbits through a microcatheter at a temperature within the high biological range. The transition from the injection temperature (high biological range) to body temperature (basal for the animals) quickly solidified the embolic agent without the occurrence of dehydration, therefore overcoming the main limitation of LCST-typed poly(N-isopropylacrylamide) previously reported. Angiography and histological examination demonstrated the successful embolization of both renal arteries and no recanalization was observed after 8 weeks. The PNAGA-based supramolecular copolymer hydrogel is a novel embolic agent that allows for the occlusion of larger sized arteries in a biocompatible environment. PMID- 27709139 TI - The suppression of metastatic lung cancer by pulmonary administration of polymer nanoparticles for co-delivery of doxorubicin and Survivin siRNA. AB - A pH-sensitive co-delivery system was designed for the treatment of metastatic lung cancers by pulmonary delivery of doxorubicin (DOX) and Survivin siRNA. Conjugates PEI-BMPH-DOX (PMD) of polyethylenimine (PEI) with DOX were developed via a pH-sensitive hydrazine bond (3-maleimidopropionic acid hydrazide, BMPH). Furthermore, the PMD/Survivin siRNA complex nanoparticles were prepared by electrostatic interaction between cationic PMD and anionic Survivin siRNA. The drug release of DOX from PMD conjugates increased with decreasing pH values. The DOX and Survivin siRNA could be effectively delivered into the same cells and enhanced the cytotoxicity in B16F10 cells. In the B16F10 tumor-bearing mice models, local delivery of PMD/siRNA complex nanoparticles by pulmonary delivery resulted in the preferential accumulation of DOX and siRNA in the lungs, and a considerable amount of DOX and siRNA accumulated in tumor tissues of the lungs, but limited DOX and siRNA were observed in normal lung tissues. Moreover, the PMD/Survivin siRNA complex nanoparticles showed enhanced antitumor efficacy compared with the mono-delivery of DOX or Survivin siRNA. Taken together, our findings offer an effective local delivery strategy by pulmonary administration for the treatment of metastatic lung cancer. PMID- 27709138 TI - PEG-based hydrogels prepared by catalyst-free thiol-yne addition and their post antibacterial modification. AB - PEG-based hydrogels possess tissue-like mechanical elasticity, solute permeability, cytocompatibility and biocompatibility. In this work, PEG-based hydrogels were prepared via nucleophilic thiol-yne addition between a 4-arm PEG functionalized with thiols (PEG10k-4-SH) and an electron-deficient alkyne (PEG10k 4-PP). The as-fabricated hydrogels still possess residual functionalities, enabling a second nucleophilic thiol-yne addition on the gel matrix. A thiol containing fluorescent dye was conjugated with the electron-deficient alkyne appended hydrogels. A thiol-containing antimicrobial peptide (AMP-SH) was also embedded into the gel matrix via nucleophilic thiol-yne addition. The inhibition of bacterial growth in suspensions and contaminated substrate surfaces by the AMP embedded hydrogels was studied. The cytotoxicity of unmodified and AMP-embedded PEG-based hydrogels against 3T3 fibroblasts was investigated by 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) viability assay.

PMID- 27709146 TI - Convex and concave micro-structured silicone controls the shape, but not the polarization state of human macrophages. AB - The typical foreign body response (FBR) to synthetic implants is characterized by local inflammation and tissue fibrosis. Silicone implants have been associated with the development of adverse capsular contraction (ACC); a form of excessive FBR to the material that often requires the replacement of the implant. It has been shown that surface roughening of silicone can reduce the prevalence of ACC, but the mechanisms remain poorly understood. Macrophages are key cells in FBR. They exert their control mainly by polarizing into pro-inflammatory (M1) or pro healing (M2) cells. It is postulated that surface topography can reduce M1 polarization by limiting cell spreading and cytoskeleton organization. To test this hypothesis, we used KrF Excimer laser ablation with half-tone masks to produce convex and concave topographies with controlled surface dimensional parameters. Cells in convex and concave topographies were compared to cells in planar surfaces, with or without chemical polarization. We show that chemical polarization induced specific changes in the cell shape on planar substrates. Macrophage shape and size was different in concave and convex surfaces, but no correlation was found with the cell polarization state. The results highlight that chemical polarization of macrophages is associated with changes in the cell shape; however, topography-induced changes in macrophage shape could not be linked with a shift in macrophage polarization. Thus, the sole manipulation of cell shape does not seem to be the mechanism by which macrophage function could be controlled.

AB - Since centuries, the rapid spread and cure of infectious diseases have been a major concern to the progress and survival of humans. These diseases are a global burden and the prominent cause for worldwide deaths and disabilities. Nanomedicine has emerged as the most excellent tool to eradicate and halt their spread. Various nanoformulations (NFs) using advanced nanotechnology are in demand. Recently, hydrogel and nanogel based drug delivery devices have posed new prospects to simulate the natural intelligence of various biological systems. Owing to their unique porous interpenetrating network design, hydrophobic drug incorporation and stimulus sensitivity hydrogels owe excellent potential as targeted drug delivery systems. The present review is an attempt to highlight the recent trends of hydrogel based drug delivery systems for the delivery of therapeutic agents and diagnostics for major infectious diseases including acquired immune deficiency syndrome (AIDS), malaria, tuberculosis, influenza and ebola. Future prospects and challenges are also described. PMID- 27709148 TI - Inorganic-organic hybrid white light phosphors.

AB - A high performance three-dimensional (3D) thiophene-annulated perylene dye, namely tetra-PBI-S, was designed and synthesized. The appropriate LUMO level, balanced carrier mobilities and favourable phase separation make tetra-PBI-S based solar cells show a much higher power conversion efficiency (PCE) of 6.2% than tetra-PBI based solar cells with a PCE of 3.6%.

AB - N-Acylhomoserine lactones are autoinducers of quorum sensing (QS) in Gram negative bacteria. We exploit here the role of structurally related beta-lactones in the inhibition of Vibrio harveyi bioluminescence and identify a derivative with nanomolar potency. Surprisingly, QS was not affected and combined proteomic/biochemical studies revealed insights into the cellular mode of action.

AB - In this communication, we describe the synthesis of new chiral alumina nanofilms and surfaces. Our method is based on chiral templating of alumina nanofilms by cellulose microfibers using the atomic layer deposition process. The chiral nature of the alumina nanofilms was characterized by a variety of techniques, such as quartz crystal microbalance, chiral circular-dichroism adsorption, chiral high-performance liquid chromatography and cyclic voltammetry measurements.

AB - A strategy of "macro-micro-nano" organization is reported for embedding oxide encapsulated-nanoparticles onto monolithic substrates in one-step with the aid of molecularly defined cross-linking agents. Such catalysts, with enhanced heat/mass transfer and high permeability, are qualified for several harsh reaction processes such as CH4/VOC abatement, gas-phase hydrogenation of dimethyl oxalate and oxidative dehydrogenation of ethane.

AB - The enantioselective total synthesis of the 3,4-fused indole alkaloid ht-13-A has been achieved. The synthesis features a zinc-mediated propargylation, a rhodium catalyzed intramolecular C-H activation reaction, and a methylamine-mediated cyclization. This concise and efficient synthetic approach can be applied for the gram-scale synthesis of ht-13-A. PMID- 27709220 TI - Nanospring electrochemical lithography (NEL): noble metal nanohelices. AB - We report three-dimensional helical Au nanostructures using anodized aluminum oxide (AAO) and the embedded Pd nanosprings, serving as primary and secondary templates, respectively. The resulting Au nanohelices exhibit strong SERS signals due to the electromagnetic field enhancement originating from the helical morphology; this behavior is seemingly analogous to that of a nano-gap enhancer. Nanospring electrochemical lithography (NEL) represents a new method for synthesizing complex helical nanostructures and has potential for application in materials science. PMID- 27709221 TI - Evaluation of an intra-articular synthetic ligament for treatment of cranial cruciate ligament disease in dogs: a six-month prospective clinical trial. AB - OBJECTIVE: Evaluate the short-term outcomes of a novel synthetic ligament for treatment of naturally occurring canine cranial cruciate ligament disease. STUDY DESIGN: Prospective clinical study. ANIMALS: Dogs with unilateral cranial cruciate ligament disease (n = 50). METHODS: Patient parameters evaluated included a five-point lameness score, evaluation of craniocaudal stifle instability, and radiographic findings over 24 weeks. Any postoperative complications were recorded. RESULTS: Thirty-four out of 42 dogs experienced significant improvements in lameness between the preoperative and 24 week time points. Lameness scores in those dogs improved significantly at all measured time intervals after postoperative week 2. Recurrence of stifle instability increased significantly over the study period from immediate postoperative measurements. Cranial drawer recurred in seven out of 42 of dogs by week 4 and 18/42 by week 24. Implant changes were not noted between the immediate and six-month postoperative radiographs except where complications occurred. Overall, 25 dogs experienced a total of 32 complications (22 major and 10 minor). Sixteen dogs had major complications, and nine had minor complications. CONCLUSION: The procedure was generally effective at improving lameness scores, but did not consistently maintain postoperative stifle stability and had an unacceptably high complication rate. This synthetic ligament procedure cannot be recommended for use in its current form. PMID- 27709222 TI - Pullout strength of monocortical and bicortical screws in metaphyseal and diaphyseal regions of the canine humerus. AB - OBJECTIVE: Monocortical screws are commonly employed in locking plate fixation, but specific recommendations for their placement are lacking and use of short monocortical screws in metaphyseal bone may be contraindicated. Objectives of this study were to evaluate axial pullout strength of two different lengths of monocortical screws placed in various regions of the canine humerus compared to bicortical screws, and to derive cortical thickness and bone density values for those regions using quantitative computed tomography analysis (QCT). METHODS: The QCT analysis was performed on 36 cadaveric canine humeri for six regions of interest (ROI). A bicortical, short monocortical, or 50% transcortical 3.5 mm screw was implanted in each ROI and axial pullout testing was performed. RESULTS: Bicortical screws were stronger than monocortical screws in all ROI except the lateral epicondylar crest. Short monocortical metaphyseal screws were weaker than those placed in other regions. The 50% transcortical screws were stronger than the short monocortical screws in the condyle. A linear relationship between screw length and pullout strength was observed. CLINICAL SIGNIFICANCE: Cortical thickness and bone density measurements were obtained from multiple regions of the canine humerus using QCT. Use of short monocortical screws may contribute to failure of locking plate fixation of humeral fractures, especially when placed in the condyle. When bicortical screw placement is not possible, maximizing monocortical screw length may optimize fixation stability for distal humeral fractures. PMID- 27709223 TI - Tibial plateau levelling osteotomy in eleven cats with cranial cruciate ligament rupture. AB - OBJECTIVE: To report the surgical procedure, intra- and postoperative complications, and short-term follow-up of tibial plateau levelling osteotomy (TPLO) in feline patients with cranial cruciate ligament (CrCL) rupture using a 2.0 or 2.4 mm Synthes(r) TPLO plate. STUDY DESIGN: Prospective study. MATERIAL AND METHODS: Eleven cats with a CrCL rupture were included in the study. Inspection of intra-articular structures was carried out via arthroscopy or arthrotomy. Each patient was re-examined one and 10 days after surgery. Orthopaedic examination and follow-up radiographs were obtained four to 12 weeks postoperatively. RESULTS: Two meniscopathies and one partial CrCL rupture were detected. Minor intra-operative complications occurred in five cats (suboptimal positioning of the plate [n = 3], proximal fibular fracture [n = 1], a visible osteotomy gap [n = 1]). Postoperatively, minor complications were detected in three cats (mild patellar desmitis [n = 2], superficial wound infection [n = 1]). No additional surgical reintervention, graded as major complication, was necessary. Four to eight weeks postoperatively, all cats showed no to mild intermittent lameness. Complete bone union was apparent within four to 12 weeks. Owners reported a high level of comfort and mobility during the last follow-up. CONCLUSION: The preliminary results of this study support the use of TPLO in cats, but larger case numbers are needed to evaluate its practicability, as well as long-term outcome (>1 year), especially evaluating the development and the clinical relevance of osteoarthritis. PMID- 27709224 TI - The effect of intramedullary pin size and plate working length on plate strain in locking compression plate-rod constructs under axial load. AB - OBJECTIVE: To investigate the effect of intramedullary pin size and plate working length on plate strain in locking compression plate-rod constructs. METHODS: A synthetic bone model with a 40 mm fracture gap was used. Locking compression plates with monocortical locking screws were tested with no pin (LCP-Mono) and intramedullary pins of 20% (LCPR-20), 30% (LCPR-30) and 40% (LCPR-40) of intramedullary diameter. Two screws per fragment modelled a long (8-hole) and short (4-hole) plate working length. Strain responses to axial compression were recorded at six regions of the plate via three-dimensional digital image correlation. RESULTS: The addition of a pin of any size provided a significant decrease in plate strain. For the long working length, LCPR-30 and LCPR-40 had significantly lower strain than the LCPR-20, and plate strain was significantly higher adjacent to the screw closest to the fracture site. For the short working length, there was no significant difference in strain across any LCPR constructs or at any region of the plate. Plate strain was significantly lower for the short working length compared to the long working length for the LCP-Mono and LCPR-20 constructs, but not for the LCPR-30 and LCPR-40 constructs. CLINICAL SIGNIFICANCE: The increase in plate strain encountered with a long working length can be overcome by the use of a pin of 30-40% intramedullary diameter. Where placement of a large diameter pin is not possible, screws should be placed as close to the fracture gap as possible to minimize plate strain and distribute it more evenly over the plate. PMID- 27709225 TI - Increased circulating resistin is associated with insulin resistance, oxidative stress and platelet activation in type 2 diabetes mellitus. AB - Resistin is an adipokine that promotes inflammation and insulin resistance by targeting several cells including platelets. We hypothesised that in type 2 diabetes (T2DM), resistin may foster in vivo oxidative stress, thromboxane dependent platelet activation and platelet-derived inflammatory proteins release, key determinants of atherothrombosis. A cross-sectional comparison of circulating resistin, sCD40L, as a marker of platelet-mediated inflammation, asymmetric dimethylarginine (ADMA), endothelial dysfunction marker, Dickkopf (DKK)-1, reflecting the inflammatory interaction between platelets and endothelial cells, and urinary 8-iso-PGF2alpha and 11-dehydro-TxB2, reflecting in vivo lipid peroxidation and platelet activation, respectively, was performed between 79 T2DM patients and 30 healthy subjects. Furthermore, we investigated the effects of the alpha-glucosidase inhibitor acarbose and the PPARgamma agonist rosiglitazone, targeting hyperglycaemia or insulin resistance, versus placebo, in 28 and 18 T2DM subjects, respectively. Age- and gender-adjusted serum resistin levels were significantly higher in patients than in controls. HOMA (beta=0.266, p=0.017) and 11-dehydro-TXB2 (beta=0.354, p=0.002) independently predicted resistin levels. A 20-week treatment with acarbose was associated with significant reductions (p=0.001) in serum resistin, DKK-1, urinary 11-dehydro-TXB2 and 8-iso-PGF2alpha with direct correlations between the change in serum resistin and in other variables. A 24-week rosiglitazone treatment on top of metformin was associated with significant decreases in resistin, DKK-1, 11-dehydro-TXB2 and 8-iso PGF2alpha, in parallel with HOMA decrease. In conclusion, resistin, antagonising insulin action in part through PPARgamma activation, may favour insulin resistance and enhance oxidative stress, endothelial dysfunction and platelet activation. The adipokine-platelet interactions may be involved in platelet insulin resistance and their consequent pro-aggregatory phenotype in this setting. PMID- 27709226 TI - Epidemiology of first and recurrent venous thromboembolism in patients with active cancer. A population-based cohort study. AB - Population studies on the incidence of venous thromboembolism (VTE) in patients with active cancer are limited. An observational cohort study was undertaken to estimate the incidence of first and recurrent VTE. The source population consisted of all patients in the UK Clinical Practice Research Datalink, with additional information on hospitalisation and cause of death, between 2001 and 2011. A cancer-related clinical diagnosis or therapy within the 90 days before or after a VTE constituted an active-cancer-associated VTE. Incidence rates of first VTE among patients with active cancer and incidence rates of recurrent VTE during the 10-year observational period after a first VTE event were estimated. Incidence rates of all-cause mortality and age- and gender-specific mortality were also calculated. There were 6,592 active-cancer-associated VTEs with a total of 112,738 cancer-associated person-years of observation. The incidence rate of first VTE in patients with active cancer was 5.8 (95 % confidence interval 5.7 6.0) per 100 person-years. A first VTE recurrence was observed in 591 patients. The overall incidence rate for recurrence was 9.6 (95 % confidence interval 8.8 10.4) per 100 person-years, with a peak at 22.1 in the first six months. Recurrence rates were similar after initial pulmonary embolism and after initial deep-vein thrombosis. The mortality risk after VTE was considerable, with 64.5 % mortality after one year and 88.1 % after 10 years. VTE in patients with active cancer is common and associated with high recurrence and mortality rates. Efforts are needed to prevent VTE and reduce recurrence, especially in the first year after VTE diagnosis. PMID- 27709227 TI - Is Meeting the Recommended Dietary Allowance (RDA) for Protein Related to Body Composition among Older Adults?: Results from the Cardiovascular Health of Seniors and Built Environment Study. AB - OBJECTIVE: Studies suggest protein intake may be associated with lower body weight, but protein has also been associated with preservation of lean body mass. Understanding the role of protein in maintaining health for older adults is important for disease prevention among this population. DESIGN: Cross-sectional study of the relationship of dietary protein on body composition. SETTING: New York City community centers. PARTICIPANTS: 1,011 Black, White, and Latino urban men and women 60-99 years of age. MEASUREMENTS: Protein intake was assessed using two interviewer-administered 24-hour recalls, and body composition was assessed using bioelectrical impedance analysis (BIA) of fat mass (kg) (FM), fat free mass (kg) (FFM), and impedance resistance (Ohms). STATISTICAL ANALYSIS: Indices of FM and FFM were calculated by dividing BIA measurements by height squared (m2), and percent FFM was calculated by dividing FFM by the sum of FM and FFM. Log linear models adjusting for age (continuous), race/ethnicity, education, physical activity (dichotomized at the median), hypertension, diabetes, and total calories (continuous). RESULTS: Just 33% of women and 50% of men reported meeting the RDA for protein. Both fat free mass index (FFMI) and fat mass index (FMI) were negatively associated with meeting the RDA for protein (Women: FFMI -1.78 95%CI [ 2.24, -1.33], FMI -4.12 95% CI [-4.82, -3.42]; Men: FFMI -1.62 95% CI [-2.32, 0.93] FMI -1.80 95% CI [-2.70, -0.89]). After accounting for confounders, women and men consuming at least 0.8 g/kg/day had a 6.2% (95% CI: 5.0%, 7.4%) and a 3.2% (95% CI 1.1%, 5.3%) higher percent fat free mass, respectively. CONCLUSIONS: FFM, FFMI, FM, and FMI were inversely related to meeting the RDA for protein. Meeting the RDA for protein of at least 0.8g/kg/day was associated with a higher percentage of fat free mass among older adults. These results suggest meeting the protein recommendations of at least 0.8 g/kg/day may help to promote lower overall body mass, primarily through loss of fat mass rather than lean mass. PMID- 27709228 TI - Mini Nutritional Assessment Short-Form: Validation in Five Latin American Cities. SABE Study. AB - OBJECTIVES: To validate the short-form of the MNA (MNA-SF) and the cut-off point of 31 cm for calf circumference (CC) in older people in Latin America. METHODS: A cross-sectional study was conducted with 5,722 community-dwelling older subjects (range: 60-102 years) in Latin America's five main cities: Sao Paulo (Brazil), Santiago (Chile), Havana (Cuba), Mexico DF (Mexico) and Montevideo (Uruguay). All participants underwent an interview, which included anthropometric measurements, completing the MNA and obtaining socio-demographic, nutrition and health information. The short-form of the MNA consists of only six questions from the original 18. It has two versions: one using body mass index (BMI) and the second using CC as a surrogate. Cohen's Kappa was calculated to assess the agreement between the MNA and the MNA-SF; diagnostic tests were performed, and Receiver operating characteristic (ROC) curves were developed. Criterion-related validity was assessed in the Chilean sample. RESULTS: Both version of the MNA-SF showed high sensitivity and specificity with the MNA, showing good accuracy (0.88), although higher values were estimated for malnutrition and risk of malnutrition in the total sample by sex. The cut-off point of 31 cm for CC showed high sensitivity (74.6-94.4%), specificity (72.6-100%) and good area under the ROC curve (0.87-0.95) when compared with BMI. There was good agreement between MNA and both version of MNA-SF for identifying persons with malnutrition or a risk of malnutrition in the five cities (Kappa coefficient: 0.6193-0.7852). CONCLUSION: Both versions of the MNA-SF are population-screening tools of easy and fast application, with good accuracy for assessing malnutrition and risk of malnutrition in Latin American older people. PMID- 27709229 TI - Prevalence of and Risk Factors for Dysphagia in the Community Dwelling Elderly: A Systematic Review. AB - OBJECTIVES: This review clarifies current information regarding the prevalence of and risk factors associated with dysphagia (swallowing disorders) in the community dwelling elderly (CDE). A better understanding of prevalence and characteristics of dysphagia in the CDE will help to determine the scope of this problem. Understanding the scope of dysphagia is a critical first step towards early identification, management, and prevention of dysphagia related morbidities in the CDE. METHODS: Studies identified from multiple electronic databases (MEDLINE (Pubmed), PsychInfo, Google Scholar, EBSCO, PROQUEST, Web of Science and WorldCat dissertations and theses) evaluating prevalence and risk factors for dysphagia in the CDE were reviewed. Data from all eligible studies were abstracted by the first author and independently reviewed by two raters, using the Newcastle-Ottawa scale (NOS). RESULTS: 15 studies (n = 9947 participants) were eligible for inclusion. Studies included were all observational: 14 cross sectional and 1 prospective cohort. Significant heterogeneity was observed in methodology among studies of dysphagia in the CDE. The average NOS study quality rating was 4.54 points (SD: 0.9), with a mode of 4 points (range 3-6). Only 6 of the 15 studies were identified as high quality research studies, with a mean of 5.33 points (SD: 0.47). Among reviewed studies, the prevalence of swallowing difficulty in the CDE ranged from 5% to 72%. However, the average prevalence of dysphagia estimated from the 6 high quality studies was 15%. Reported risk factors associated with dysphagia include advancing age; history of clinical disease; and physical frailty, including reduced ability to carry out activities of daily living. CONCLUSION: Research on dysphagia in CDE is modest and consists mostly of observational studies with diverse methodology. However, prevalence rate of 15% from the high quality research suggests a significant public health impact of this impairment. Identification of specific risk factors that cause dysphagia in the CDE is premature, given the rigor of published studies. Future research efforts should focus on developing a valid definition and assessment of dysphagia in this population before clarifying causative risk factors. PMID- 27709230 TI - Metabolic Syndrome Is not an Independent Risk Factor for Hearing Impairment. AB - OBJECTIVE: We aimed to investigate the association between metabolic syndrome (MS) and hearing impairment (HI) using nationally representative data from Korean adults. DESIGN, SETTING AND PARTICIPANTS: A total of 16,799 subjects (>=19 years old; 7,170 men and 9,629 women) who underwent pure tone audiometry testing were included in the analysis. Data were obtained from the fifth Korea National Health and Nutrition Examination Survey (2010-2012). Subjects were divided into two groups according to the presence of MS. RESULTS: Among the subjects with MS, 47% had HI. Logistic regression analysis revealed that MS was not an independent risk factor for HI, although increased fasting plasma glucose (OR 1.4, 95% CI: 1.1 1.8) was independently associated with HI. In addition, older age, male sex, very low body mass index (<=17.5 kg/m2), lower education level, smoking history, and occupational noise exposure were independently associated with HI. For low frequency HI, independent risk factors included older age, lower educational level, lower economic status, and very low BMI (<=17.5 kg/m2). For high-frequency HI, independent risk factors included older age, male sex, lower educational level, lower economic status, increased blood pressure, lower high-density lipoprotein cholesterol, and smoking history. CONCLUSIONS: MS itself was not an independent risk factor for HI, and, among the individual metabolic components, only increased fasting plasma glucose was independently associated with HI. PMID- 27709231 TI - Novel Therapy of Hyperhomocysteinemia in Mild Cognitive Impairment, Alzheimer's Disease, and Other Dementing Disorders. AB - OBJECTIVES: Studies have produced conflicting results assessing hyperhomocysteinemia (HYH) treatment with B vitamins in patients with normal cognition, Alzheimer's disease and related disorders (ADRD). This study examined the effect of HYH management with L-methylfolate (LMF), methylcobalamin (MeCbl; B12), and N-acetyl-cysteine (CFLN: Cerefolin(r)/Cerefolin-NAC(r)) on cognitive decline. DESIGN: Prospective, case-control study of subjects followed longitudinally. SETTING: Outpatient clinic for cognitive disorders. PARTICIPANTS: 116 ADRD patients (34 with HYH, 82 with No-HYH) met inclusion and exclusion criteria to participate. No study participant took B vitamins. INTERVENTION: HYH patients received CFLN, and No-HYH patients did not. MEASUREMENTS: Cognitive outcome measures included MCI Screen (memory), CERAD Drawings (constructional praxis), Ishihara Number Naming (object recognition), Trails A and B (executive function), and F-A-S test (verbal fluency). Dependent or predictor measures included demographics, functional severity, CFLN and no CFLN treatment duration, ADRD diagnosis, memantine and cholinesterase inhibitor treatment. Linear mixed effects models with covariate adjustment were used to evaluate rate of change on cognitive outcomes. RESULTS: The duration of CFLN treatment, compared to an equivalent duration without CFLN treatment, significantly slowed decline in learning and memory, constructional praxis, and visual-spatial executive function (Trails B). CFLN treatment slowed cognitive decline significantly more for patients with milder baseline severity. CFLN treatment effect increased as baseline functional severity decreased. The analytical model showed that treatment duration must exceed some minimum period of at least one year to slow the rate of cognitive decline. CONCLUSION: After covariate adjustment, HYH+CFLN significantly slowed cognitive decline compared to No-HYH+No-CFLN. Longer CFLN treatment duration, milder baseline severity, and magnitude of homocysteine reduction from baseline were all significant predictors. There are a number of factors that could account for disagreement with other clinical trials of B vitamin treatment of HYH. Moreover, CFLN is chemically distinct from commonly used B vitamins as both LMF and MeCbl are the fully reduced and bioactive functional forms; CLFN also contains the glutathione precursor, N-acetyl cysteine. The findings of other B vitamin trials of HYH can, therefore, only partly account for treatment effects of CFLN. These findings warrant further evaluation with a randomized, placebo-controlled trial. PMID- 27709232 TI - A Study on Neuroprotective Effects of Curcumin on the Diabetic Rat Brain. AB - The present study was aimed to study the neuroprotective therapeutic effect of curcumin on the male albino rat brain. Subarachnoid hemorrhage leads to severe mortality rate and morbidity, and oxidative stress is a crucial factor in subarachnoid hemorrhage. Therefore, we investigated the effect of curcumin on oxidative stress and glutamate and glutamate transporter-1 on a subarachnoid hemorrhage-induced male albino rats. The curcumin commonly used for the treatment and saline used for the control. Curcumin (10 mg/kg bwt) dissolved in saline and administered orally to the rats for one week. Glutamate, glutamate transporter-1, malondialdehyde (MDA), superoxide dismutase (SOD), catalase, glutathione reductase and lactate dehydrogenase (LDH) activities were determined. Glutamate level was lower in the curcumin-treated rats compared to their respective controls. Glutamate transporter-1 did not alter in the curcumin-treated rats compared to their controls. Glutamate transporter-1 protein expression is significantly reduced in the curcumin-treated rats. MDA levels decreased 18 and 29 % in the hippocampus and the cortex region respectively. SOD (17% and 32%), and catalase (19% and 24%) activities were increased in the curcumin-treated hippocampus and the cortex region respectively. Glutathione reductase (13% and 19%) and LDH (21% and 30%) activities were increased in the treated hippocampus and the cortex region respectively. The mRNA expression of NK-kB and TLR4 was significantly reduced following curcumin treatment. Taking all these data together, the curcumin found to be effective against oxidative stress and glutamate neurotoxicity in the male albino rats. PMID- 27709233 TI - Vitamin C Supplementation, APOE4 Genotype and Cognitive Functioning in a Rural Dwelling Cohort. AB - OBJECTIVE: Apolipoprotein E4 (APOE4) genotype has been implicated as a moderating factor in cognitive function studies. Although prior studies have suggested that vitamin C is associated with better cognitive function in elders, link between the two has been mixed. Limited data exist as to whether the APOE4 genotype influences these associations. Therefore, this study sought to determine whether the association between vitamin C and cognition in a rural community dwelling cohort differs by the APOE4 genotype. DESIGN AND PARTICIPANTS: Data were analyzed on 582 participants (n=183 men; n=399 women) from a rural community-based cohort. Cognition was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status and The Executive Interview. APOE genotyping was ascertained by standard methods. The relation between vitamin C supplementation and cognition were analyzed first with ANOVA and then ANCOVA with age, gender, education as covariates. Analyses were initially run in the full sample and then split by APOE4 presence (yes/no). RESULTS: Overall, Vitamin C supplementation was associated with significantly better immediate memory (p=0.04), visuospatial skills (p=0.002), language (p=0.01), and global cognitive functioning (p=0.006). Among APOE4 non-carriers, vitamin C supplementation was positively associated with immediate memory (F[1,392] =6.7, p=0.01), visuospatial skills (F[1,391]=10.6, p=0.001), language (F[1,392]=13.0, p<0.001), attention (F[1,386]=7.9, p=0.005, and global cognition (F[1,382]=11.0, p=0.001. However, there was no significant link between vitamin C supplementation and cognition among APOE4 carriers. CONCLUSION: Vitamin C supplementation was found to be positively associated with cognition among this rural-dwelling community-based sample; however, the associations appeared to differ by APOE4 status. These data may suggest that targeted genotype-specific cognitive enhancement studies are needed to clarify the potential benefits of vitamin C supplementation. PMID- 27709234 TI - Early Nutritional Follow-Up after Discharge Prevents Deterioration of ADL Functions in Malnourished, Independent, Geriatric Patients Who Live Alone - A Randomized Clinical Trial. AB - OBJECTIVES: To compare the effects of two nutritional follow-up interventions with regard to preventing short-term deterioration in ADL, and to compare their effects on physical function, emotional health, and health-related quality of life. DESIGN: Randomized clinical trial with two intervention groups and one control group, and a follow-up period of eight weeks. SETTING: Intervention in the participants' homes after discharge from hospital. PARTICIPANTS: Inclusion: Malnourished geriatric patients and patients at risk of malnutrition (MNA<24), aged 75 years and older, living at home and alone. Exclusion: Nursing home residents and patients with terminal illnesses or cognitive impairment. Randomization: At discharge, the patients were assigned to one of three groups: 'home visit', 'telephone consultation', or 'control' group. INTERVENTION: Individually tailored nutritional counselling of the patient and the patient's daily home carer by a clinical dietician one, two, and four weeks after discharge from hospital. The counselling was either in-person at the patients' homes, or by telephone. The control group received no follow-up after discharge. MEASUREMENTS: Primary outcome: Change in ADL (Barthel-100 score) at discharge and eight weeks later. SECONDARY OUTCOMES: Change in physical performance (handgrip strength, 30 sec. chair stand test, CAS), quality of life and depression measurements (SF-36, Depression List, Geriatric Depression Score), and Avlund mobility-tiredness score (Mob-T). RESULTS: Two-hundred and eight participants were randomized, 73 to home visits and 68 to telephone consultations. The control group comprised 67 patients. The mean age of the participants was 86.1 years. At eight weeks after discharge, 157 completed the follow-up (home visit 52, telephone consultation 51, and control group 54). The mean age of these patients was 85.8 years. More patients in the home visit group improved or maintained their ADL (96%), compared to the telephone (75%) and control groups (72%), p<0.01. No difference was detected among the groups with regard to physical measurements, health-related quality of life, and emotional health. CONCLUSION: Early nutritional follow-up after discharge, performed as home visits, prevents deterioration of ADL in malnourished, independent, geriatric patients who live alone and thereby preserves their independence. PMID- 27709235 TI - Frailty, Diabetes, and Mortality in Middle-Aged African Americans. AB - BACKGROUND: Older adult frail diabetics have high mortality risk, but data are limited regarding frail late middle-aged diabetics, especially for African Americans. The aim of this study is to examine the association of diabetes with health outcomes and frailty in the African American Health (AAH) study. METHODS: AAH is a population-based longitudinal cohort study. Participants were African Americans (N=998) ages 49 to 65 years at baseline. Cross-sectional comparisons for diabetes included disability, function, physical performance, cytokines, and frailty. Frailty measures included the International Academy of Nutrition and Aging [FRAIL] frailty scale, Study of Osteoporotic Fractures [SOF] frailty scale, Cardiovascular Health Study [CHS] frailty scale, and Frailty Index [FI]). Longitudinal associations for diabetes included new ADLs >= 1 and mortality at 9 year follow-up. RESULTS: Diabetics were more likely to be frail using any of the 4 frailty scales than were non-diabetics. Frail diabetics, compared to nonfrail diabetics, reported significantly increased falls in last 1 year, higher IADLs and higher LBFLs. They demonstrated worse performance on the SPPB, one-leg stand, and grip strength; and higher Tumor Necrosis Factor receptors (sTNFR1 and sTNFR2). Mortality and 1 or more new ADLs also were increased among frail compared to nonfrail diabetics when followed for 9 years. CONCLUSIONS: Frailty in middle-aged African American persons with diabetes is associated with having more disability and functional limitations, worse physical performance, and higher cytokines (sTNFR1 and sTNFR2 only). Middle-aged African Americans with diabetes have an increased risk of mortality and frail diabetics have an even higher risk of death, compared to nonfrail diabetics. PMID- 27709236 TI - Pre-Frailty, Frailty, and Multimorbidity: Prevalences and Associated Characteristics from Two French National Surveys. AB - OBJECTIVE: To estimate the prevalence of pre-frailty, frailty and multimorbidity in individuals without disability in France. To describe independent determinants of each indicators. DESIGN: Two nationally representative cross-sectional French surveys. SETTINGS: Wave 2012 of the Health, Health Care and Insurance Survey (Enquete Sante et Protection Sociale, ESPS) and data from the Disability Healthcare Household section Survey (Enquete Handicap Sante - Menages, HSM) from 2008. PARTICIPANTS: Two representative samples of the French population aged 55 and older (n=4,328 and n=12,295). MEASUREMENTS: Frailty was assessed using Fried's frailty phenotype and multimorbidity was defined as having had at least two groups of the following groups of comorbidities in the last 12 months (cardio or cerebrovascular disease, diabetes, chronic respiratory disease, arthralgia, depression). Independent determinants were studied using weighted logistic regressions. RESULTS: In the French population over 55 and free of disability, 55 to 62% of individuals were either frail, pre-frail or multimorbid, 22 to 25% being frail or multimorbid. ESPS and HSM prevalences for frailty (11.1% [9.3% 12.1%] and 12.3% [11.5%-13.0%]) and multimorbidity (14.9% [13.6%-16.2%] and 16.8% [15.9%-17.7%]) were consistent across studies. Both frailty and multimorbidity prevalences were associated with age. On the other hand, pre-frailty prevalence varied consistently between studies (from 38 to 48%) and was not significantly associated with age. We found that more than 60% of frail subjects did not present with multimorbidity and around 70% of subjects with multimorbidity were not frail. Determinants of pre-frailty and multimorbidity but not frailty depended on sex. Similar factors were associated with frailty and multimorbidity in women (older age, functional decline, poor mental health, financial difficulties) while only poor mental health was independently associated with both indicators in men. CONCLUSION: Our study highlights that in France, among individuals older than 55 years-old and free of disability, around 25% are either frail or multimorbid; another 30% to 40% being pre-frail. Pre-frailty, frailty and multimorbidity are known to be associated with adverse health outcomes and important economic costs. The health system must adapt to respond to the needs of its aging population. In addition, given the efficient impact of prevention actions, our findings emphasize the need to implement prevention strategies against Frailty and multimorbidity in France. PMID- 27709237 TI - Visual Impairment Screening at the Geriatric Frailty Clinic for Assessment of Frailty and Prevention of Disability at the Gerontopole. AB - OBJECTIVES: To evaluate visual performance and factors associated with abnormal vision in patients screened for frailty at the Geriatric Frailty Clinic (GFC) for Assessment of Frailty and Prevention of Disability at Toulouse University Hospital. DESIGN: Retrospective, observational cross-sectional, single-centre study. SETTING: Institutional practice. PARTICIPANTS: Patients were screened for frailty during a single-day hospital stay between October 2011 and October 2014 (n = 1648). MEASUREMENTS: Collected medical records included sociodemographic data (including living environment and educational level), anthropometric data, and clinical data. The general evaluation included the patient's functional status using the Activities of Daily Living (ADL) scale and the Instrumental Activity of Daily Living (IADL) scale, the Mini-Mental State Examination (MMSE) for cognition testing, and the Short Physical Performance Battery (SPPB) for physical performance. We also examined Body Mass Index (BMI), the Mini Nutritional Assessment (MNA), and the Hearing Handicap Inventory for the Elderly Screening (HHIE-S) tool. The ophthalmologic evaluation included assessing visual acuity using the Snellen decimal chart for distant vision, and the Parinaud chart for near vision. Patients were divided into groups based on normal distant/near vision (NDV and NNV groups) and abnormal distant/near vision (ADV and ANV groups). Abnormal distant or near vision was defined as visual acuity inferior to 20/40 or superior to a Parinaud score of 2, in at least one eye. Associations with frailty-associated factors were evaluated in both groups. RESULTS: The mean age of the population was 82.6 +/- 6.2 years. The gender distribution was 1,061 females (64.4%) and 587 males (35.6%). According to the Fried criteria, 619 patients (41.1%) were pre-frail and 771 (51.1%) were frail. Distant and near vision data were available for 1425 and 1426 patients, respectively. Distant vision was abnormal for 437 patients (30.7%). Near vision was abnormal for 199 patients (14%). Multiple regression analysis showed that abnormal distant vision as well as abnormal near vision were independently associated with greater age (P < 0.01), lower educational level (P < 0.05), lower performance on the MMSE (P < 0.001), and lower autonomy (P < 0.02), after controlling for age, gender, educational level, Fried criteria, and MMSE score. CONCLUSION: The high prevalence of visual disorders observed in the study population and their association with lower autonomy and cognitive impairment emphasises the need for systematic screening of visual impairments in the elderly. Frailty was not found to be independently associated with abnormal vision.

AB - The state of the art of inclusion complex formation between cyclodextrins and ionic liquids is reported. Mechanisms, stoichiometries, and binding constants are summarized and classified by anion. We investigated the supramolecular interactions between the beta-cyclodextrin cavity and six ionic liquids based on 1-dodecyl-3-methylimidazolium by affinity capillary electrophoresis and compared the results with those obtained by isothermal titration calorimetry. We show that the presence of basic or acidic buffers leads to a metathesis reaction, underlining the limitation of the affinity capillary electrophoresis technique. PMID- 27709239 TI - Patient-specific instruments for total knee arthroplasty can accurately predict the component size as used peroperative. AB - PURPOSE: Patients-specific instruments (PSI) for implantation of total knee arthroplasty (TKA) can be used to predict the implant size for both the femur and the tibia component. This study aims to determine the impact of approval of the PSI planning for TKA on the frequency of, and reason for intraoperative changes of implant sizes. METHODS: The clinical records of 293 patients operated with MRI (90.4 %) and CT-based (9.6 %) PSI were reviewed for actual used implant size. Preoperative default planning from the technician and approved planning by the operating surgeon were compared with the intraoperative implanted component size for both the femur and tibia. Intraoperative reason for not following the default sizes was outdated. Furthermore, MRI- and CT-based PSI were compared for these outcomes. RESULTS: In 93.9 and 91.1 % for, respectively, the femur and tibia (n.s.), the surgeon planned size was implanted during surgery. The predicted size of the femur (p < 0.00) and the tibia (p < 0.00) component planned by a technician differed from the implanted component sizes in 62 (21.2 %) and 51 (17.4 %) patients, respectively. In 17 cases, the femoral component size was adapted intraoperative based on the expert opinion of the operating surgeon. In 26 cases, the tibia component was changed during the surgery because of a mediolateral overhang, sclerotic bone, medial or lateral release, limited extension and/or fixed varus deformity. The results between the MRI- and CT-based PSI did not differ (n.s.). CONCLUSIONS: PSI is a tool to help the surgeon to achieve the best possible results during TKA. The planning made by a technician should always be validated and approved by the operating surgeon who has the ultimate responsibility regarding the operation. With PSI, the operating surgeon is able to minimize intraoperative implant size errors in advance to improve operating room efficiency with possible lowering hospital costs per procedure. LEVELS OF EVIDENCE: III. PMID- 27709238 TI - Body Composition and Anti-Neoplastic Treatment in Adult and Older Subjects - A Systematic Review. AB - BACKGROUND: The estimation of the risk of poor tolerance and overdose of antineoplastic agents protocols represents a major challenge in oncology, particularly in older patients. We hypothesize that age-related modifications of body composition (i.e. increased fat mass and decreased lean mass) may significantly affect tolerance to chemotherapy. METHOD: We conducted a systematic review for the last 25 years (between 1990 and 2015), using US National library of Medicine Medline electronic bibliographic database and Embase database of cohorts or clinical trials exploring (i) the interactions of body composition (assessed by Dual X-ray Absorptiometry, Bioelectrical Impedance Analyses, or Computerized Tomography) with pharmacokinetics parameters, (ii) the tolerance to chemotherapy, and (iii) the consequences of chemotherapies or targeted therapies on body composition. RESULTS: Our search identified 1504 articles. After a selection (using pre-established criteria) on titles and abstract, 24 original articles were selected with 3 domains of interest: impact of body composition on pharmacokinetics (7 articles), relationship between body composition and chemotoxicity (14 articles), and effect of anti-cancer chemotherapy on body composition (11 articles). The selected studies suggested that pharmacokinetic was influenced by lean mass, that lower lean mass could be correlated with toxicity, and that sarcopenic patients experienced more toxicities that non sarcopenic patients. Regarding fat mass, results were less conclusive. No studies specifically explored the topic of body composition in older cancer patients. CONCLUSIONS: Plausible pathophysiological pathways linking body composition, toxicity, and pharmacokinetics are sustained by the actual review. However, despite the growing number of older cancer patients, our review highlighted the lack of specific studies in the field of anti-neoplastic agents toxicity regarding body composition conducted in elderly. PMID- 27709241 TI - [Ambulatory care of patients with somatically unexplained complaints : A comparative qualitative study]. AB - BACKGROUND: The aim of this study was to compare the approach of general practitioners (GP) and outpatient specialists for psychiatry, neurology or psychosomatic medicine to patients with somatically unexplained complaints. METHODS: Qualitative interviews were conducted with general practitioners in Berlin and with outpatient specialists. Interviews were analyzed by qualitative content analysis. RESULTS: Both GPs and specialists rarely used structured diagnostic instruments. Guidelines are seen and used with reservation throughout the different specialties. Similar to the GPs, most of the specialists surveyed in this study had reservations against the necessity of a precise coding according to the International Classification of Diseases (ICD). CONCLUSION: In outpatient care the concern for the individual patient is the connecting element between different medical specialties. This results in a differential diagnostic and therapeutic approach that is not automatically in line with guidelines. The development of common concepts in ambulatory care might help to meet the demands of this complex group of patients with somatically unexplained complaints. PMID- 27709242 TI - [Care differences in a consultation and liaison service]. AB - BACKGROUND: The investigation of the real density of care by a consultation liaison service (CLS) as a function of patient groups, settings and diagnoses makes sense with respect to a better allocation of resources. OBJECTIVE: Are there differences concerning the density of care by a CLS in a general hospital depending on patient groups and on the psychiatric diagnosis? METHOD: A retrospective (2012-2015) survey of all consultations (n = 7081 corresponding to 4080 patients) was carried out based on the CLS documentation for quality assurance. Bivariate tests (i.e. chi2-test and ANOVA) and multivariate linear and logistic models were used to investigate group differences and associations. RESULTS: The number of consultations achieved corresponded to 3.2 % of the total admissions to hospital, especially internal medicine (22.3 %), surgery (26.1 %) as well as gynecology and obstetrics (21.1 %). A suicide attempt was the reason for treatment in 3.3 %. Each patient received on average 1.7 consultations lasting 75 min but only 25 % received 2 or more consultations. Patients with psychiatric comorbidities, non-oncology patients as well as female and young patients received a more intensive care by CLS. Patients with depressive and somatoform disorders received a higher density of treatment. DISCUSSION: The psychotherapeutic interventions performed did not follow the expected diagnostic patterns in other settings. Systemic interventions with indirect treatment should be given priority in older patients and especially in patients with organic mental disorders. PMID- 27709243 TI - [Anatomy and biomechanics of the scaphoid]. AB - The scaphoid is biomechanically and clinically of great importance for function of the wrist. In the literature, its anatomy and biomechanics are clearly underrepresented as well as underestimated. In the following review the scaphoid will be presented in more detail, according to recent information and findings. Not only will the origin of the name and the history of previous names, such as cotyloid or navicular, be introduced, but also for the first time in medical literature the significant phylogeny and ontogeny of the scaphoid will be shown. Moreover, the clinically very important blood supply, the ligaments of the scaphoid and relevant biomechanical details will be described.

PMID- 27709245 TI - Cystic fibrosis: a clinical view. AB - Cystic fibrosis (CF), a monogenic disease caused by mutations in the CFTR gene on chromosome 7, is complex and greatly variable in clinical expression. Airways, pancreas, male genital system, intestine, liver, bone, and kidney are involved. The lack of CFTR or its impaired function causes fat malabsorption and chronic pulmonary infections leading to bronchiectasis and progressive lung damage. Previously considered lethal in infancy and childhood, CF has now attained median survivals of 50 years of age, mainly thanks to the early diagnosis through neonatal screening, recognition of mild forms, and an aggressive therapeutic attitude. Classical treatment includes pancreatic enzyme replacement, respiratory physiotherapy, mucolitics, and aggressive antibiotic therapy. A significant proportion of patients with severe symptoms still requires lung or, less frequently, liver transplantation. The great number of mutations and their diverse effects on the CFTR protein account only partially for CF clinical variability, and modifier genes have a role in modulating the clinical expression of the disease. Despite the increasing understanding of CFTR functioning, several aspects of CF need still to be clarified, e.g., the worse outcome in females, the risk of malignancies, the pathophysiology, and best treatment of comorbidities, such as CF-related diabetes or CF-related bone disorder. Research is focusing on new drugs restoring CFTR function, some already available and with good clinical impact, others showing promising preliminary results that need to be confirmed in phase III clinical trials. PMID- 27709246 TI - Functional Metagenomics as a Tool for Identification of New Antibiotic Resistance Genes from Natural Environments. AB - Antibiotic resistance has become a major concern for human and animal health, as therapeutic alternatives to treat multidrug-resistant microorganisms are rapidly dwindling. The problem is compounded by low investment in antibiotic research and lack of new effective antimicrobial drugs on the market. Exploring environmental antibiotic resistance genes (ARGs) will help us to better understand bacterial resistance mechanisms, which may be the key to identifying new drug targets. Because most environment-associated microorganisms are not yet cultivable, culture-independent techniques are essential to determine which organisms are present in a given environmental sample and allow the assessment and utilization of the genetic wealth they represent. Metagenomics represents a powerful tool to achieve these goals using sequence-based and functional-based approaches. Functional metagenomic approaches are particularly well suited to the identification new ARGs from natural environments because, unlike sequence-based approaches, they do not require previous knowledge of these genes. This review discusses functional metagenomics-based ARG research and describes new possibilities for surveying the resistome in environmental samples. PMID- 27709248 TI - Two injection digital block versus single subcutaneous palmar injection block for finger lacerations. AB - PURPOSE: We aimed to compare two digital nerve block techniques in patients due to traumatic digital lacerations. METHODS: This was a randomized-controlled study designed prospectively in the emergency department of a university-based training and research hospital. Randomization was achieved by sealed envelopes. Half of the patients were randomised to traditional (two-injection) digital nerve block technique while single-injection digital nerve block technique was applied to the other half. Score of pain due to anesthetic infiltration and suturing, onset time of total anesthesia, need for an additional rescue injection were the parameters evaluated with both groups. Epinephrin added lidocaine hydrochloride preparation was used for the anesthetic application. Visual analog scale was used for the evaluation of pain scores. Outcomes were compared by using Mann-Whitney U test and Student t-test. RESULTS: Fifty emergency department patients >=18 years requiring digital nerve block were enrolled in the study. Mean age of the patients was 33 (min-max: 19-86) and 39 (78 %) were male. No statistically significant difference was found between the two groups in terms of our main parameters; anesthesia pain score, suturing pain score, onset time of total anesthesia and rescue injection need. CONCLUSION: Single injection volar digital nerve block technique is a suitable alternative for digital anesthesias in emergency departments. PMID- 27709249 TI - Cocaine-like discriminative stimulus effects of amphetamine, cathinone, methamphetamine, and their 3,4-methylenedioxy analogs in male rhesus monkeys. AB - RATIONALE: Synthetic cathinones have emerged as the newest class of abused monoamine transporter substrates. Structurally, these compounds are all beta ketone amphetamine (cathinone) analogs. Whether synthetic cathinone analogs produce differential behavioral effects from their amphetamine analog counterparts has not been systematically examined. Preclinical drug discrimination procedures have been useful for determining the structure activity relationships (SARs) of abused drugs; however, direct comparisons between amphetamine and cathinone analogs are lacking and, in particular, in non-human primate models. OBJECTIVES: The study aim was to determine the potency and time course of (+/-)-amphetamine, (+/-)-cathinone, and (+/-)-methamphetamine and their 3,4-methylenedioxy analogs (+/-)-MDA, (+/-)-MDC, and (+/-)-MDMA, respectively, to produce cocaine-like discriminative stimulus effects. If cathinone analogs have similar behavioral pharmacological properties to their amphetamine counterparts, then we would predict similar potencies and efficacies to produce cocaine-like discriminative stimulus effects. METHODS: Male rhesus monkeys (n = 4) were trained to discriminate intramuscular cocaine (0.32 mg/kg) from saline in a two key food-reinforced discrimination procedure. RESULTS: Racemic amphetamine, cathinone, and methamphetamine produced dose-dependent and full substitution, >=90 % cocaine-appropriate responding, in all monkeys. Addition of 3,4 methylenedioxy moiety attenuated both the potency and efficacy of amphetamine (MDA), cathinone (MDC), and methamphetamine (MDMA) to produce full cocaine-like effects. Moreover, the cocaine-like effects of amphetamine and cathinone were attenuated to a greater extent than those of methamphetamine or previously published methcathinone (Smith et al. 2016). CONCLUSION: The presence of an N methyl group blunted both the potency and the efficacy shift of the 3,4 methylenedioxy addition for both amphetamine and cathinone analogs.

PMID- 27709247 TI - Spatiotemporal Characterization of San Francisco Bay Denitrifying Communities: a Comparison of nirK and nirS Diversity and Abundance. AB - Denitrifying bacteria play a critical role in the estuarine nitrogen cycle. Through the transformation of nitrate into nitrogen gas, these organisms contribute to the loss of bioavailable (i.e., fixed) nitrogen from low-oxygen environments such as estuary sediments. Denitrifiers have been shown to vary in abundance and diversity across the spatial environmental gradients that characterize estuaries, such as salinity and nitrogen availability; however, little is known about how their communities change in response to temporal changes in those environmental properties. Here, we present a 1-year survey of sediment denitrifier communities along the estuarine salinity gradient of San Francisco Bay. We used quantitative PCR and sequencing of functional genes coding for a key denitrifying enzyme, dissimilatory nitrite reductase, to compare two groups of denitrifiers: those with nirK (encoding copper-dependent nitrite reductase) and those with nirS (encoding the cytochrome-cd 1-dependent variant). We found that nirS was consistently more abundant and more diverse than nirK in all parts of the estuary. The abundances of the two genes were tightly linked across space but differed temporally, with nirK peaking when temperature was low and nirS peaking when nitrate was high. Likewise, the diversity and composition of nirK- versus nirS-type communities differed in their responses to seasonal variations, though both were strongly determined by site. Furthermore, our sequence libraries detected deeply branching clades with no cultured isolates, evidence of enormous diversity within the denitrifiers that remains to be explored. PMID- 27709251 TI - Low validation rate of quantitative trait loci for Gibberella ear rot resistance in European maize. AB - KEY MESSAGE: Six quantitative trait loci (QTL) for Gibberella ear rot resistance in maize were tested in two different genetic backgrounds; three QTL displayed an effect in few near isogenic line pairs. Few quantitative trait loci (QTL) mapping studies for Gibberella ear rot (GER) have been conducted, but no QTL have been verified so far. QTL validation is prudent before their implementation into marker-assisted selection (MAS) programs. Our objectives were to (1) validate six QTL for GER resistance, (2) evaluate the QTL across two genetic backgrounds, (3) investigate the genetic background outside the targeted introgressions. Pairs of near isogenic lines (NILs) segregating for a single QTL (Qger1, Qger2, Qger10, Qger13, Qger16, or Qger21) were developed by recurrent backcross until generation BC3S2. Donor parents (DP) carrying QTL were backcrossed to a susceptible (UH009) and a moderately resistant (UH007) recurrent parent. MAS was performed using five SNP markers covering a region of 40 cM around each QTL. All NILs were genotyped with the MaizeSNP50 assay and phenotyped for GER severity and deoxynivalenol and zearalenone content. Traits were significantly (P < 0.001) intercorrelated. Out of 34 NIL pairs with the UH009 genetic background, three pairs showed significant differences in at least one trait for three QTL (Qger1, Qger2, Qger13). Out of 25 NIL pairs with the UH007 genetic background, five pairs showed significant differences in at least one trait for two QTL (Qger2, Qger21). However, Qger16, Qger10 and Qger13 were most likely false positives. The genetic background possibly affected NIL pairs comparisons due to linkage drag and/or epistasis with residual loci from the DP in non-target regions. In conclusion, validation rates were disappointingly low, which further indicates that GER resistance is controlled by many low-effect QTL. PMID- 27709252 TI - Host plant quantitative trait loci affect specific behavioral sequences in oviposition by a stem-mining insect. AB - KEY MESSAGE: Genetic diversity in quantitative loci associated with plant traits used by insects as cues for host selection can influence oviposition behavior and maternal choice. Host plant selection for oviposition is an important determinant of progeny performance and survival for phytophagous insects. Specific cues from the plant influence insect oviposition behavior; but, to date, no set of host plant quantitative trait loci (QTLs) have been shown to have an effect on behavioral sequences leading to oviposition. Three QTLs in wheat (Triticum aestivum L.) have been identified as influencing resistance to the wheat stem sawfly (WSS) (Cephus cinctus Norton). Wheat near-isogenic lines (NILs) for each of the three QTLs were used to test whether foraging WSS were able to discriminate variation in plant cues resulting from allelic changes. A QTL on chromosome 3B (Qss-msub-3BL) previously associated with stem solidness and larval antibiosis was shown to affect WSS oviposition behavior, host preference, and field infestation. Decreased preference for oviposition was also related to a QTL allele on chromosome 2D (Qwss.msub-2D). A QTL on chromosome 4A (Qwss.msub-4A.1) affected host plant attractiveness to foraging females, but did not change oviposition preference after females landed on the stem. These findings show that oviposition decisions regarding potential plant hosts require WSS females to discriminate signals from the plant associated with allelic variation at host plant quantitative loci. Allele types in a host plant QTL associated with differential survival of immature progeny can affect maternal choices for oviposition. The multidisciplinary approach used here may lead to the identification of plant genes with important community consequences, and may complement the use of antibiosis due to solid stems to control the wheat stem sawfly in agroecosystems. PMID- 27709254 TI - ? PMID- 27709253 TI - Statin use decreases coagulation in users of vitamin K antagonists. AB - PURPOSE: The purpose of the study is to determine the immediate and long-term effect of statins on coagulation in patients treated with vitamin K antagonists (VKAs). METHODS: We selected patients on VKAs of two Dutch anticoagulation clinics who initiated treatment with a statin between 2009 and 2013. Patients who initiated or stopped concomitant drugs that interact with VKAs or were hospitalised during follow-up were excluded. The VKA dosage (mg/day) after statin initiation was compared with the last VKA dosage before the statin was started. Immediate and long-term differences in VKA dosage (at 6 and 12 weeks) were calculated with a paired student t test. RESULTS: Four hundred thirty-five phenprocoumon users (mean age 70 years, 60 % men) and 303 acenocoumarol users (mean age 69 years, 58 % men) were included. After start of statin use, the immediate phenprocoumon dosage was 0.02 mg/day (95 % CI, 0.00 to 0.03) lower. At 6 and 12 weeks, these phenprocoumon dosages were 0.03 (95 % CI, 0.01 to 0.05) and 0.07 mg/day (95 % CI, 0.04 to 0.09) lower as compared with the dosage before first statin use. In acenocoumarol users, VKA dosage was 0.04 mg/day (95%CI, 0.01 to 0.07) (immediate effect), 0.10 (95 % CI, 0.03 to 0.16) (at 6 weeks), and 0.11 mg/day (95 % CI, 0.04 to 0.18) (after 12 weeks) lower. CONCLUSIONS: Initiation of statin treatment was associated with an immediate and long-term minor although statistically significant decrease in VKA dosage in both phenprocoumon and acenocoumarol users, which suggests that statins may have anticoagulant properties.

PMID- 27709258 TI - The utility of diffusion-weighted imaging to assess acute renal parenchymal changes due to unilateral ureteral stone obstruction. AB - Our aim in this study was to evaluate the use of diffusion-weighted imaging (DWI) for acute renal parenchymal changes occurring as a result of unilateral ureteral obstruction due to stones. Twenty four patients with obstructed and opposite unobstructed kidney were enrolled in this prospective study. DWI was used at two different b values (b = 0 s/mm2 and b = 1000 s/mm2). Apparent diffusion coefficient (ADC) measurements were completed on the upper pole, central section and lower pole parenchyma of both kidneys. ADC values were calculated. The unpaired t test was used to assess differences between the groups. The results of measurements identified a reduction in ADC values in obstructed renal parenchyma compared to unobstructed opposite renal parenchyma. The reduction in ADC values was greater in the upper and lower pole parenchyma and was statistically significant (p < 0.001, for both). Diffusion changes in renal parenchyma due to acute unilateral ureteral obstruction linked to stone may be quantitatively shown with DWI. The reduction in ADC values was more pronounced in the upper and lower pole parenchyma. PMID- 27709259 TI - A "doughnut" in the abdomen.

Diagnostic imaging included atypical soft-tissue infection, fibrogranulomatous reaction, gouty tophus, rheumatoid nodule and xanthoma or possibly malignancy. The histopathological examination revealed sarcoidosis involving the prepatellar bursa. PMID- 27709261 TI - [Non-selective primary prevention programs for childhood overweight : An overview]. AB - BACKGROUND: Despite an obvious stabilization the prevalence of childhood overweight and obesity is still too high. Since childhood obesity may track into adulthood and lead to major health consequences, effective primary prevention programs are of high relevance. OBJECTIVE: In recent years several universal primary prevention programs, measures or projects have been developed and evaluated in Germany. This paper gives an overview. METHODS: An internet search and a search in the archive of the Deutsche Arzteblatt were conducted to identify universal programs in Germany from 2006 to 2015. We used the combination of primary prevention, children, obesity and project for this online search. RESULTS: We identified 38 programs and measures. After exclusion of non-adequate interventions (e. g. selective instead of universal) and any duplicates we selected 13 projects to be described. DISCUSSION: Some projects provided insufficient information since they have not been adequately published. On the positive side, most projects simultaneously addressed various potential risk factors and achieved a successful networking of various relevant actors. In addition, many projects strived for creating the groundwork to allow for a sustainable change in the living environment of children. However, despite the fact that the concept of most projects was theory-based in most cases only weak intervention effects were observed on strong endpoints like anthropometric indicators and on health-related behaviors. PMID- 27709262 TI - [Prevention of overweight and obesity in children and adolescents : Critical appraisal of the evidence base]. AB - BACKGROUND: Despite careful planning and implementation, overweight/obesity prevention interventions in children and adolescents typically show no, inconsistent or merely weak effects. Such programs usually aim at behavior changes, rarely also at environmental changes, that draw upon conventional wisdom regarding the commonly accepted determinants of childhood overweight/obesity. OBJECTIVE: This paper evaluates the evidence base of the apparently overweight /obesity-related determinants diet, physical activity and stress. The results of international intervention studies are discussed against this background. METHODS AND MATERIALS: Based on the mediating-moderating variable model, we investigate the effect of theory specified mediating variables and how potential moderating variables may impact these relationships. RESULTS: Contrary to common beliefs, recent research has revealed inconsistent evidence regarding associations between potentially obesogenic behaviors and overweight/obesity in youth. Moreover, the evidence for strong and causal relationships between mediating variables and targeted behaviors seems to be inconsistent. In addition, inadequate attention is paid to moderating effects. DISCUSSION: The etiology of overweight/obesity in youth is likely the result of a complex interplay of multi-causal influences. Future prevention interventions would benefit from a more thorough understanding of the complex relationships that have been hypothesized and of the mechanisms of suspected behaviors for affecting overweight/obesity. Only if substantial change can be demonstrated in mediators with reasonable effort under real world circumstances, it will make sense to progress to community behavior change trials.

We aim to establish a European society of paediatric and neonatal intensive care (ESPNIC) experts' definition of paediatric RSS. METHODS: We conducted a two-round Delphi study followed by an observational multicentre retrospective study. One hundred and fourteen paediatric intensivists answered a clinical case-based, two-round Delphi survey, identifying clinical items consistent with RSS. Multivariate analysis of these items in a development single centre cohort (70 patients, 30 % mortality) facilitated development of RSS definitions based on either a bedside or computed severity score. Both scores were subsequently tested in a validation cohort (six centres, 424 patients, 11.6 % mortality). RESULTS: From the Delphi process, the draft definition included evidence of myocardial dysfunction and high blood lactate levels despite high vasopressor treatment. When assessed in the development population, each item was independently associated with the need for extracorporeal life support (ECLS) or death. Resultant bedside and computed septic shock scores had high discriminative power against the need for ECLS or death, with areas under the receiver operating characteristics curve of 0.920 (95 % CI 0.89-0.94), and 0.956 (95 % CI 0.93 0.97), respectively. RSS defined by a bedside score equal to or higher than 2 and a computed score equal to or higher than 3.5 was associated with a significant increase in mortality. CONCLUSIONS: This ESPNIC definition of RSS accurately identifies children with the most severe form of septic shock.

AB - BACKGROUND: Co-infection is frequently seen in critically ill patients with influenza, although the exact rate is unknown. We determined the rate of co infection, the risk factors and the outcomes associated with co-infection in critically ill patients with influenza over a 7-year period in 148 Spanish intensive care units (ICUs). METHODS: This was a prospective, observational, multicentre study. Influenza was diagnosed using the polymerase chain reaction. Co-infection had to be confirmed using standard bacteriological tests. The primary endpoint of this analysis was the presence of community-acquired co infection, with secondary endpoints including ICU, 28-day and hospital mortality. RESULTS: Of 2901 ICU patients diagnosed with influenza, 482 (16.6 %) had a co infection. The proportion of cases of co-infection increased from 11.4 % (110/968) in 2009 to 23.4 % (80/342) in 2015 (P < 0.001). Compared with patients without co-infection, patients with co-infection were older [adjusted odds ratio (aOR) 1.1, 95 % confidence interval 1.1-1.2; P < 0.001] and were more frequently immunosuppressed due to existing HIV infection (aOR 2.6 [1.5-4.5]; P < 0.001) or preceding medication (aOR 1.4 [1.1-1.9]; P = 0.03). Co-infection was an independent risk factor for ICU mortality (aOR 1.4 [1.1-1.8]; P < 0.02), 28-day mortality (aOR 1.3 [1.1-1.7]; P = 0.04) and hospital mortality (aOR 1.9 [1.5 2.5]; P < 0.001). CONCLUSIONS: Co-infection in critically ill patients with influenza has increased in recent years. In this Spanish cohort, age and immunosuppression were risk factors for co-infection, and co-infection was an independent risk factor for ICU, 28-day and hospital mortality.

AB - : TIMAP (TGFbeta-inhibited membrane-associated protein) is an endothelium enriched TGFbeta downstream protein and structurally belongs to the targeting subunit of myosin phosphatase; however, the mechanism of TGFbeta repressing TIMAP and its functional relevance to TGFbeta bioactivity remain largely unknown. Here, we report that TIMAP is reduced in TGFbeta-elevated mouse fibrotic kidney and highly expressed in macrophages. TGFbeta repression of TIMAP is associated with HDAC3 upregulation and its recruitment by Smad2/3 at the Smad binding element on TIMAP promoter, whereas specific HDAC3 inhibition reversed the TIMAP repression, suggesting that TGFbeta transcriptionally downregulates TIMAP through HDAC3 associated Smad signaling. Further investigation showed that TIMAP over expression interrupted TGFbeta-associated Smad signaling and TIMAP repression by TGFbeta correlated with TGFbeta-induced macrophage M2 polarization markers, migration, and phagocytosis-the processes promoted by phosphorylation of the putative TIMAP substrate myosin light chain (MLC). Consistently, TIMAP dephosphorylated MLC in macrophages and TGFbeta induced macrophage migration and phagocytosis in TIMAP- and MLC phosphorylation-dependent manners, suggesting that TIMAP dephosphorylation of MLC constitutes an essential regulatory loop mitigating TGFbeta-associated macrophage M2 phenotypic activities. Given that hyperactive TGFbeta often causes excessive macrophage phagocytic activities potentially leading to various chronic disorders, the strategies targeting HDAC3/TIMAP axis might improve TGFbeta-associated pathological processes. KEY MESSAGE: TIMAP is enriched in the endothelium and highly expressed in macrophages. TIMAP is suppressed by TGFbeta via HDAC3-associated Smad signaling. TIMAP inhibits TGFbeta signaling and TGFbeta-associated macrophage M2 polarization. TIMAP dephosphorylation of MLC counteracts TGFbeta-induced macrophage phagocytosis. PMID- 27709266 TI - Nicotine protects against DSS colitis through regulating microRNA-124 and STAT3. AB - : Although it is generally believed that nicotine accounts for the beneficial effect of smoking on ulcerative colitis, the underlying mechanisms remain not well understood. Our previous finding that nicotine inhibits inflammatory responses through inducing miR-124 prompted us to ask whether the miRNA is involved in the protective action of nicotine against UC. Our present study found that miR-124 expression is upregulated in colon tissues from UC patients and DSS colitis mice. Nicotine treatment further augmented miR-124 expression in lymphocytes isolated from human ulcerative colonic mucosa and ulcerative colon tissues from DSS mice, both in infiltrated lymphocytes and epithelial cells. Moreover, knockdown of miR-124 significantly diminished the beneficial effect of nicotine on murine colitis and IL-6-treated Caco-2 colon epithelial cells. Further analysis indicated that nicotine inhibited STAT3 activation in vivo and in IL-6 treated Caco-2 cells and Jurkat human T lymphocytes, in which miR-124 knockdown led to increased activation of STAT3. Blocking STAT3 activity alone is beneficial for DSS colitis and also abolished nicotine's protective effect in this model. These data indicate that nicotine exerts its protective action in UC through inducing miR-124 and inhibiting STAT3, and suggest that the miR-124/STAT3 system is a potential target for the therapeutic intervention of UC. KEY MESSAGE: Nicotine upregulates miR-124 expression in ulcerative colon tissues and cells. MiR-124 is required for the protective role of nicotine in DSS colitis mice and epithelial cells. The protective effect of nicotine in murine DSS colitis depends on blocking STAT3 activation. MiR-124 mediates the inhibitory role of nicotine on STAT3/p-STAT3. Targeting miR-124 and STAT3 represents a novel approach for treating ulcerative colitis. PMID- 27709268 TI - The neuronal metabolite NAA regulates histone H3 methylation in oligodendrocytes and myelin lipid composition. AB - The neuronal mitochondrial metabolite N-acetylaspartate (NAA) is decreased in the multiple sclerosis (MS) brain. NAA is synthesized in neurons by the enzyme N acetyltransferase-8-like (NAT8L) and broken down in oligodendrocytes by aspartoacylase (ASPA) into acetate and aspartate. We have hypothesized that NAA links the metabolism of axons with oligodendrocytes to support myelination. To test this hypothesis, we performed lipidomic analyses using liquid chromatography tandem mass spectrometry (LC-MS/MS) and high-performance thin-layer chromatography (HPTLC) to identify changes in myelin lipid composition in postmortem MS brains and in NAT8L knockout (NAT8L-/-) mice which do not synthesize NAA. We found reduced levels of sphingomyelin in MS normal appearing white matter that mirrored decreased levels of NAA. We also discovered decreases in the amounts of sphingomyelin and sulfatide lipids in the brains of NAT8L-/- mice compared to controls. Metabolomic analysis of primary cultures of oligodendrocytes treated with NAA revealed increased levels of alpha ketoglutarate, which has been reported to regulate histone demethylase activity. Consistent with this, NAA treatment resulted in alterations in the levels of histone H3 methylation, including H3K4me3, H3K9me2, and H3K9me3. The H3K4me3 histone mark regulates cellular energetics, metabolism, and growth, while H3K9me3 has been linked to alterations in transcriptional repression in developing oligodendrocytes. We also noted the NAA treatment was associated with increases in the expression of genes involved in sulfatide and sphingomyelin synthesis in cultured oligodendrocytes. This is the first report demonstrating that neuronal derived NAA can signal to the oligodendrocyte nucleus. These data suggest that neuronal-derived NAA signals through epigenetic mechanisms in oligodendrocytes to support or maintain myelination. PMID- 27709270 TI - SHP-2 phosphatase controls aryl hydrocarbon receptor-mediated ER stress response in mast cells. AB - Previously we reported that exposure of mouse and human mast cells to aryl hydrocarbon receptor (AhR) ligands resulted in reactive oxygen species (ROS)- and calcium (Ca2+)-dependent activation of mast cells in vitro and in vivo. However, the mechanisms through which the AhR-ligand axis mediates stress response, Ca2+ signaling and subsequent mast cell activation remain to be fully elucidated. Evidence is provided herein that SHP-2 is critical in regulating AhR-mediated ER stress response and intracellular Ca2+ dynamics. We found that an AhR ligand, FICZ, induced significant reduction of intracellular GSH and an increased level of intracellular ROS. Significantly, we showed that in FICZ-treated mast cells, SHP-2 promoted, in a ROS-dependent manner, ER stress response involving primarily the PERK signaling pathway, ATF4 activation and eIF2alpha phosphorylation, which could be reversed by the addition of an antioxidant, NAC, and was inhibited in cells with SHP-2 knockdown. Our findings suggested that SHP-2 is critical in controlling ER stress signals in response to AhR activation, which provides a new mechanistic insight into how the AhR-ligand axis regulates cellular adaptation to the environmental insult in mast cells.

PMID- 27709269 TI - Can augmented feedback facilitate learning a reactive balance task among older adults? AB - While concurrent augmented visual feedback of the center of pressure (COP) or center of gravity (COG) can improve quiet standing balance control, it is not known whether such feedback improves reactive balance control. Additionally, it is not known whether feedback of the COP or COG is superior. This study aimed to determine whether (1) concurrent augmented feedback can improve reactive balance control, and (2) feedback of the COP or COG is more effective. Forty-eight healthy older adults (60-75 years old) were randomly allocated to one of three groups: feedback of the COP, feedback of the COG, or no feedback. The task was to maintain standing while experiencing 30 s of continuous pseudo-random perturbations delivered by a moving platform. Participants completed 25 trials with or without feedback (acquisition), immediately followed by 5 trials without feedback (immediate transfer); 5 trials without feedback were completed after a 24-h delay (delayed transfer). The root mean square error (RMSE) of COP-COG, electrodermal level, and co-contraction index were compared between the groups and over time. All three groups reduced RMSE and co-contraction index from the start of the acquisition to the transfer tests, and there were no significant between-group differences in RMSE or co-contraction on the transfer tests. Therefore, all three groups learned the task equally well, and improved balance was achieved with practice via a more efficient control strategy. The two feedback groups reduced electrodermal level with practice, but the no-feedback group did not, suggesting that feedback may help to reduce anxiety. PMID- 27709272 TI - In vivo cardiomyocyte response to YTX- and AZA-1-induced damage: autophagy versus apoptosis. AB - Yessotoxins (YTX) and azaspiracids (AZAs) are marine toxins produced by phytoplanktonic dinoflagellates that get accumulated in filter feeding shellfish and finally reach human consumers through the food web. Both toxin classes are worldwide distributed, and food safety authorities have regulated their content in shellfish in many countries. Recently, YTXs and AZAs have been described as compounds with subacute cardiotoxic potential in rats owed to alterations of the cardiovascular function and ultrastructural heart damage. These molecules are also well known in vitro inducers of cell death. The aim of this study was to explore the presence of cardiomyocyte death after repeated subacute exposure of rats to AZA-1 and YTX for 15 days. Because autophagy and apoptosis are often found in dying cardiomyocytes, several autophagic and apoptotic markers were determined by western blot in heart tissues of these rats. The results showed that hearts from YTX-treated rats presented increased levels of the autophagic markers microtubule-associated protein light chain 3-II (LC3-II) and beclin-1, nevertheless AZA-1-treated hearts evidenced increased levels of the apoptosis markers cleaved caspase-3 and -8, cleaved PARP and Fas ligand. Therefore, while YTX-induced damage to the heart triggers autophagic processes, apoptosis activation occurs in the case of AZA-1. For the first time, activation of cell death signals in cardiomyocytes is demonstrated for these toxins with in vivo experiments, which may be related to alterations of the cardiovascular function. PMID- 27709273 TI - Impact of a Novel Bioabsorbable Implant on Radiation Treatment Planning for Breast Cancer. AB - BACKGROUND: Techniques for accurately delineating the tumor bed after breast conserving surgery (BCS) can be challenging. As a result, the accuracy, and efficiency of radiation treatment (RT) planning can be negatively impacted. Surgically placed clips or the post-surgical seroma are commonly used to determine target volume; however, these methods can lead to a high degree of uncertainty and variability. A novel 3-dimensional bioabsorbable marker was used during BCS and assessed for its impact on RT planning. METHODS: One hundred and ten implants were sutured to the margins of the tumor bed excision site in 108 patients undergoing BCS. Routine CT imaging of the breast tissue was performed for RT planning, and the marker was assessed for visibility and utility in target delineation. RT regimens, target volumes and associated treatment costs were analyzed. RESULTS: In all patients, the marker was easily visible and in 95.7 % of cases, it proved useful for RT planning. 36.8 % of patients received conventional whole breast irradiation plus boost, 56.6 % received hypo fractionation plus boost, and 6.6 % received accelerated partial breast irradiation. A shift toward increased use of hypo-fractionated regimens was noted over the three year period of this study. There were no device-related complications or cancer recurrences in this group of patients. CONCLUSIONS: This study demonstrated the use of a novel 3-dimensional marker as a safe and effective method for delineating the tumor bed with a significant utility for RT planning. With routine use of the device, an increased use of hypofractionation with a resultant 25 % cost savings was noted. PMID- 27709274 TI - [Injuries to blood vessels near the heart caused by central venous catheters]. AB - Injuries to blood vessels near the heart can quickly become life-threatening and include arterial injuries during central venous puncture, which can lead to hemorrhagic shock. We report 6 patients in whom injury to the subclavian artery and vein led to life-threatening complications. Central venous catheters are associated with a multitude of risks, such as venous thrombosis, air embolism, systemic or local infections, paresthesia, hemothorax, pneumothorax, and cervical hematoma, which are not always immediately discernible. The subclavian catheter is at a somewhat lower risk of catheter-associated sepsis and symptomatic venous thrombosis than approaches via the internal jugular and femoral veins. Indeed, access via the subclavian vein carries a substantial risk of pneumo- and hemothorax. Damage to the subclavian vein or artery can also occur during deliberate and inadvertent punctures and result in life-threatening complications. Therefore, careful consideration of the access route is required in relation to the patient and the clinical situation, to keep the incidence of complications as low as possible. For catheterization of the subclavian vein, puncture of the axillary vein in the infraclavicular fossa is a good alternative, because ultrasound imaging of the target vessel is easier than in the subclavian vein and the puncture can be performed much further from the lung. PMID- 27709275 TI - [Impairment of oxygenation of patients in surgical intensive care : Early symptom of severe sepsis]. AB - BACKGROUND: Sepsis and septic shock are major contributors to morbidity and mortality in intensive care patients. Early identification and adequate therapy are of utmost importance to reduce the still high mortality in patients with severe sepsis. Many of the pathophysiologic changes are nonspecific. Thus, a combination of symptoms and laboratory results are necessary to confirm the diagnosis. Impairment of the Horovitz index is identified as being a primal prognostic criterion for early diagnosis in serious progression of sepsis, after exclusion of a few differential diagnoses. Based on this fact, the prevalence of this symptom compared to other sepsis parameters is of specific interest. METHOD: In a retrospective study 33 cases of serious sepsis were analysed during the patient's course of intensive care treatment focusing on oxygenation. The deterioration of oxygenation, meaning a drop in the Horovitz index below 200 mm Hg (25.7 kPa) or a decrease in paO2 by 67.5 mm Hg (9 kPa) in spontaneously breathing patients with sepsis was the mean inclusion criteria. We compared the sequence of occurrence of known sepsis markers (e. g. PCT, WBC, CRP) with the deterioration in oxygenation to answer the question whether impairment of oxygenation could be an early symptom of severe sepsis. The Mann Whitney U-test and a discriminant analysis were performed to verify differences of the variables investigated between surviving and deceased patients. Furthermore a regression analysis was performed to confirm the results of the discriminant analysis. RESULTS: The mean drop in the Horovitz index was 90 +/- 24 mm Hg (12 +/- 3.2 kPa) within 4.5 h respectively. This was highly significant (p < 0.001). In all patients impairment of oxygenation indicated an individual onset and further progression of a serious sepsis. In more than 3/4 of all cases this symptom occurred in an earlier stage than other organ dysfunctions. In 79 % of cases, patients showed an impairment of oxygenation before PCT increased on values of >2 ng/ml. In 76 % of cases impairment of oxygenation occurred earlier than all other investigated parameters. Significant differences were found between surviving and deceased patients regarding to their age as well as the timeframe from the beginning of impaired oxygenation to the onset of the effect of the administered antibiotics. These two parameters (age, time to sufficient antibiotic therapy) were confirmed by regression analysis and showing similar effect coefficients, age 1.09 and time to sufficient antibiotic therapy 1.04 respectively. CONCLUSION: An urgent worsening of pulmonary function in patients in intensive care requires immediate differential diagnostics due to substantial therapeutic consequences. Our results confirm that impairment of pulmonary oxygenation is the first prognostic symptom of severe onset of sepsis. Consequently, we recommend that this parameter be considered in diagnostic staging. After exclusion of a few differential diagnoses impairment of oxygenation can be the very first symptom of severe sepsis. The patient's age and time to sufficient antibiotic therapy are two very important prognostic factors with respect to mortality. Early and sufficient antibiotic therapy, and in a few cases surgical intervention are of utmost importance. PMID- 27709276 TI - The intervertebral disc, the endplates and the vertebral bone marrow as a unit in the process of degeneration. AB - OBJECTIVES: The association of disc degeneration (DD) and vertebral endplate degeneration (EPD) is still not well understood. This study aimed to find segmental predictive risk factors for DD and EPD and to illuminate associations of the disc, endplate and bone marrow changes in the process of degeneration. METHODS: After institutional review board approval, 450 lumbar levels, followed up with MRI for at least 4 years, were retrospectively graded for DD according to Pfirrmann (PFG), for EPD according to the endplate score (EPS) and according to the presence, extension and type of Modic changes (MC). Clustered logistic regression and multivariate analysis was applied in nested, matched case-control subgroups to evaluate potential local risk factors for progression. RESULTS: An EPS score of >=4 was identified as an independent risk factor for progression of DD (OR = 2.32, 95%CI:1.07-5.01,p = 0.03) and MC (OR = 5.49,95%CI:2.30-13.10,p < 0.001). Progression of DD was significantly accompanied by progression or evolution of MC (OR = 12.25,95%CI:1.49-100.6,p = 0.02) and with progression of EPS (OR = 1.71, 95%CI:1.00-1.05, p = 0.01). Once advanced DD has occurred, it becomes a risk factor for progression in EPS (OR = 2.24,95%CI:1.23-4.12,p < 0.01). CONCLUSIONS: The degenerative processes in the disc, endplate and bone marrow are highly associated. An EPS >= 4 is an independent risk factor for DD and MC progression in a population with low back pain. KEY POINTS: * The degenerative processes in the disc, endplate and bone marrow are associated. * An endplate score >=4 is a risk factor for DD and MC progression. * Modic changes are last to occur in the development of segmental intervertebral degeneration. * A new segmental grading system is suggested.

AB - OBJECTIVES: To prospectively investigate how Buscopan affects the diagnosis of bowel inflammation by diffusion-weighted imaging MR enterography (DWI-MRE) in Crohn's disease (CD). METHODS: Thirty CD patients without previous bowel surgery underwent DWI-MRE (b = 900 sec/mm2) before and after intravenous Buscopan. The 30 patients were randomly divided into two groups; using a crossover design, interpretations were made regarding the presence of restricted mural diffusion (i.e., bowel inflammation) in nine bowel segments in two separate reading sessions by two readers. The readers also judged restricted mural diffusion extent in each bowel segment on two side-by-side DWI-MRE images with a random right-to-left order. Ileocolonoscopy and conventional MRE interpreted by an expert panel were reference standards. RESULTS: We analyzed 262 bowel segments. DWI-MRE without Buscopan significantly decreased sensitivity for both readers (58.8 % vs. 72.9 %, P = 0.046; 57.6 % vs. 85.9 %, P = 0.001) and did not significantly increase specificity (P = 0.085 and 0.396). Two readers noted that 28.6 % and 23.3 % of 262 bowel segments had greater diffusion restriction extent on DWI-MRE with Buscopan compared with DWI-MRE without Buscopan (P < 0.001) and 68.7 % and 74 %, respectively, had similar extent between them. CONCLUSION: Omitting Buscopan caused a greater loss in sensitivity of DWI-MRE than false positive reduction for diagnosing bowel inflammation in CD. KEY POINTS: * Omitting Buscopan significantly decreases DWI-MRE sensitivity for diagnosing bowel inflammation in CD. * Increase in the corresponding DWI-MRE specificity by omitting Buscopan is less apparent. * DWI-MRE without Buscopan underestimates the extent of bowel inflammation in CD. PMID- 27709278 TI - Trends and patterns of computed tomography scan use among children in The Netherlands: 1990-2012. AB - OBJECTIVE: To evaluate trends and patterns in CT usage among children (aged 0-17 years) in The Netherlands during the period 1990-2012. METHODS: Lists of electronically archived paediatric CT scans were requested from the Radiology Information Systems (RIS) of Dutch hospitals which reported >10 paediatric CT scans annually in a survey conducted in 2010. Data included patient identification, birth date, gender, scan date and body part scanned. For non participating hospitals and for years prior to electronic archiving in some participating hospitals, data were imputed by calendar year and hospital type (academic, general with <500 beds, general with >= 500 beds). RESULTS: Based on 236,066 CT scans among 146,368 patients performed between 1990 and 2012, estimated annual numbers of paediatric CT scans in The Netherlands increased from 7,731 in 1990 to 26,023 in 2012. More than 70 % of all scans were of the head and neck. During the last decade, substantial increases of more than 5 % per year were observed in general hospitals with fewer than 500 beds and among children aged 10 years or older. CONCLUSION: The estimated number of paediatric CT scans has more than tripled in The Netherlands during the last two decades. KEY POINTS: * Paediatric CT in The Netherlands has tripled during the last two decades. * The number of paediatric CTs increased through 2012 in general hospitals. * Paediatric CTs continued to increase among children aged 10 years or older. PMID- 27709279 TI - Substantia nigra fractional anisotropy is not a diagnostic biomarker of Parkinson's disease: A diagnostic performance study and meta-analysis. AB - OBJECTIVES: Our goal was to estimate the diagnostic accuracy of substantia nigra fractional anisotropy (SN-FA) for Parkinson's disease (PD) diagnosis in a sample similar to the clinical setting, including patients with essential tremor (ET) and healthy controls (HC). We also performed a systematic review and meta analysis to estimate mean change in SN-FA induced by PD and its diagnostic accuracy. METHODS: Our sample consisted of 135 subjects: 72 PD, 21 ET and 42 HC. To address inter-scanner variability, two 3.0-T MRI scans were performed. MRI results of this sample were pooled into a meta-analysis that included 1,432 subjects (806 PD and 626 HC). A bivariate model was used to evaluate diagnostic accuracy measures. RESULTS: In our sample, we did not observe a significant effect of disease on SN-FA and it was uninformative for diagnosis. The results of the meta-analysis estimated a 0.03 decrease in mean SN-FA in PD relative to HC (CI: 0.01-0.05). However, the discriminatory capability of SN-FA to diagnose PD was low: pooled sensitivity and specificity were 72 % (CI: 68-75) and 63 % (CI: 58-70), respectively. There was high heterogeneity between studies (I2 = 91.9 %). CONCLUSIONS: SN-FA cannot be used as an isolated measure to diagnose PD. KEY POINTS: * SN-FA appears insufficiently sensitive and specific to diagnose PD. * Radiologists must be careful when translating mean group results to clinical practice. * Imaging protocol and analysis standardization is necessary for developing reproducible quantitative biomarkers. PMID- 27709280 TI - High rates of clinically relevant incidental findings by total-body CT scanning in trauma patients; results of the REACT-2 trial. AB - OBJECTIVES: To determine whether there is a difference in frequency and clinical relevance of incidental findings detected by total-body computed tomography scanning (TBCT) compared to those by the standard work-up (STWU) with selective computed tomography (CT) scanning. METHODS: Trauma patients from five trauma centres were randomized between April 2011 and January 2014 to TBCT imaging or STWU consisting of conventional imaging with selective CT scanning. Incidental findings were divided into three categories: 1) major finding, may cause mortality; 2) moderate finding, may cause morbidity; and 3) minor finding, hardly relevant. Generalized estimating equations were applied to assess differences in incidental findings. RESULTS: In total, 1083 patients were enrolled, of which 541 patients (49.9 %) were randomized for TBCT and 542 patients (50.1 %) for STWU. Major findings were detected in 23 patients (4.3 %) in the TBCT group compared to 9 patients (1.7 %) in the STWU group (adjusted rate ratio 2.851; 95%CI 1.337 6.077; p < 0.007). Findings of moderate relevance were detected in 120 patients (22.2 %) in the TBCT group compared to 86 patients (15.9 %) in the STWU group (adjusted rate ratio 1.421; 95%CI 1.088-1.854; p < 0.010). CONCLUSIONS: Compared to selective CT scanning, more patients with clinically relevant incidental findings can be expected by TBCT scanning. KEY POINTS: * Total-body CT scanning in trauma results in 1.5 times more incidental findings. * Evaluation by TBCT in trauma results in more patients with incidental findings. * In every category of clinical relevance, TBCT detects more incidental findings. PMID- 27709281 TI - Stratifying fibrinolytic dosing in pediatric parapneumonic effusion based on ultrasound grade correlation. AB - BACKGROUND: Complicated pleural effusion prolongs the hospital course of pneumonia. Chest tube placement with instillation of fibrinolytic medication allows efficient drain output and decreases hospital stay. OBJECTIVE: To evaluate experience with lower fibrinolytic dose for parapneumonic effusions and to assess potential dose stratification based on a simple ultrasound grading system. MATERIALS AND METHODS: We retrospectively reviewed the medical record to identify children and young adults who received fibrinolytic therapy for parapneumonic effusion and had chest tube placement by an interventional radiology service at a single children's hospital. We assessed tissue plasminogen activator (tPA) dosing and treatment duration, as well as the need for a second pleural procedure or surgical drainage. Diagnostic US images were classified as showing less than 50% pleural echogenicity (grade 1) or greater than 50% pleural echogenicity (grade 2) and were correlated with clinical parameters. RESULTS: Of 32 patients with parapneumonic effusion, all except one received at least some 1-mg tPA doses. Dosing was solely 1-mg tPA in 81% of subjects; 19% of subjects also received 2-mg tPA doses. Mean fibrinolytic duration was 3.1 days for grade 1 effusions compared to 5.4 days for grade 2 effusions. A second pleural procedure was required in 15.6% of children. Pleural drainage with fibrinolytic therapy was successful in 97%; only one child required surgical drainage. Grade 2 US differed significantly from grade 1 US, with grade 2 occurring in younger patients (P < 0.0001), smaller patients (P < 0.0001), those needing a second procedure (P = 0.001), those with positive pleural culture or polymerase chain reaction test (P = 0.006), and those with longer treatment duration (P = 0.03). CONCLUSION: A lower 1-mg dosing regimen of tissue plasminogen activator was effective in all children with less complex (grade 1 US imaging) parapneumonic effusions. Grade 2 US images correlated with younger and smaller children, presence of a pleural organism, and longer or more complicated chest tube duration. PMID- 27709283 TI - Post-treatment with cotinine improved memory and decreased depressive-like behavior after chemotherapy in rats. AB - PURPOSE: Most cancer patients treated with systemic adjuvant chemotherapy endure long-lasting side effects including decrease in concentration, forgetfulness and slower thinking, which are globally termed "chemobrain." Cotinine, the main derivative of nicotine, improved visual and spatial working memory and decreased depressive-like behavior in an animal model of chemotherapy-induced cognitive impairment. METHODS: In this study, we investigated the effect of cotinine on weight gain, locomotor activity, cognitive abilities and depressive-like behavior in rats treated with the chemotherapy mix, cyclophosphamide, methotrexate and 5 fluorouracil. Locomotor activity and depressive-like behavior were assessed using the rotarod and Porsolt's tests, respectively. Changes in cognitive abilities were determined using the novel place recognition test. RESULTS: Female rats treated with cotinine after chemotherapy, recovered weight faster, showed superior cognitive abilities and lower levels of depressive-like behavior than chemotherapy, vehicle-treated rats. CONCLUSIONS: This evidence suggests that treatment with cotinine may facilitate the recovery and diminish the cognitive consequences of chemotherapy. PMID- 27709282 TI - Effect of veliparib (ABT-888) on cardiac repolarization in patients with advanced solid tumors: a randomized, placebo-controlled crossover study. AB - PURPOSE: Veliparib (ABT-888) is an orally bioavailable potent inhibitor of poly(ADP-ribose) polymerase (PARP)-1 and PARP-2. This phase 1 study evaluated the effect of veliparib on corrected QT interval using Fridericia's formula (QTcF). METHODS: Eligible patients with advanced solid tumors received single-dose oral veliparib (200 mg or 400 mg) or placebo in a 6-sequence, 3-period crossover design. The primary endpoint was the difference in the mean baseline-adjusted QTcF between 400 mg veliparib and placebo (??QTcF) at six post-dose time points. Absence of clinically relevant QTcF effect was shown if the 95 % upper confidence bound (UCB) for the mean ??QTcF was <10 ms for all time points. An exposure response analysis was also performed. RESULTS: Forty-seven patients were enrolled. Maximum mean ??QTcF of veliparib 400 mg was 6.4 ms, with a 95 % UCB of 8.9 ms; for veliparib 200 mg, the maximum mean ??QTcF was 3.6 ms, with a 95 % UCB of 6.1 ms. No patient had a QTcF value >480 ms or change from baseline in QTcF interval >30 ms. Treatment-emergent adverse events (TEAEs) were experienced by 36.2, 48.9, and 47.8 % of patients while receiving veliparib 200 mg, veliparib 400 mg, and placebo, respectively. Most common TEAEs were nausea (12.8 %) and myalgia (8.5 %) after veliparib 200 mg, nausea (8.5 %) and vomiting (8.5 %) after veliparib 400 mg, and nausea (6.5 %) after placebo. CONCLUSIONS: Single-dose veliparib (200 mg or 400 mg) did not result in clinically significant QTc prolongation and was well tolerated in patients with advanced solid tumors.

AB - PURPOSE: Docetaxel is used to treat many cancers, and neutropenia is the dose limiting factor for its clinical use. A population pharmacokinetic pharmacodynamic (PK-PD) model was introduced to predict the development of docetaxel-induced neutropenia in Japanese patients with non-small cell lung cancer (NSCLC). METHODS: Forty-seven advanced or recurrent Japanese patients with NSCLC were enrolled. Patients received 50 or 60 mg/m2 docetaxel as monotherapy, and blood samples for a PK analysis were collected up to 24 h after its infusion. Laboratory tests including absolute neutrophil count data and demographic information were used in population PK-PD modeling. The model was built by NONMEM 7.2 with a first-order conditional estimation using an interaction method. Based on the final model, a Monte Carlo simulation was performed to assess the impact of covariates on and the predictability of neutropenia. RESULTS: A three compartment model was employed to describe PK data, and the PK model adequately described the docetaxel concentrations observed. Serum albumin (ALB) was detected as a covariate of clearance (CL): CL (L/h) = 32.5 * (ALB/3.6)0.965 * (WGHT/70)3/4. In population PK-PD modeling, a modified semi-mechanistic myelosuppression model was applied, and characterization of the time course of neutrophil counts was adequate. The covariate selection indicated that alpha1 acid glycoprotein (AAG) was a predictor of neutropenia. The model-based simulation also showed that ALB and AAG negatively correlated with the development of neutropenia and that the time course of neutrophil counts was predictable. CONCLUSION: The developed model may facilitate the prediction and care of docetaxel-induced neutropenia.

AB - Mixed-culture fermentation that does not require an energy-intensive sterilization process is a viable approach for the economically feasible production of lactic acid (LA) due to the potential use of organic waste as feedstock. This study investigated mixed-culture LA fermentation of whey, a high strength organic wastewater, in continuous mode. Variations in the hydraulic retention time (HRT) from 120 to 8 h under different pH regimes in two thermophilic reactors (55 degrees C) were compared for their fermentation performance. One reactor was maintained at a low pH (pH 3.0) during operation at HRTs of 120 to 24 h and then adjusted to pH 5.5 in the later phases of fermentation at HRTs of 24 to 8 h (R1), while the second reactor was maintained at pH 5.5 throughout the experiment (R2). Although the LA production in R1 was negligible at low pH, it increased dramatically after the pH was raised to 5.5 and exceeded that in R2 when stabilized at HRTs of 8 and 12 h. The maximum yield (0.62 g LA/g substrate fed as the chemical oxygen demand (COD) equivalent), the production rate (11.5 g/L day), and the selectivity (95 %) of LA were all determined at a 12-h HRT in R1. Additionally, molecular and statistical analyses revealed that changes in the HRT and the pH significantly affected the bacterial community structure and thus the fermentation characteristics of the experimental reactors. Bacillus coagulans was likely the predominant LA producer in both reactors. The overall results suggest that low pH start-up has a positive effect on yield and selectivity in mixed-culture LA fermentation. PMID- 27709286 TI - Effects of deep sea water and Lactobacillus paracasei subsp. paracasei NTU 101 on hypercholesterolemia hamsters gut microbiota. AB - Hypercholesterolemia is a common metabolic syndrome in modern human society. Despite that the alteration of host gut microbiota has been linked to hypercholesterolemia in previous studies, the key host-microbiota interaction of hypercholesterolemia remains elusive. Lactobacillus paracasei subsp. paracasei NTU 101 (NTU 101) and deep sea water (DSW) were known for cholesterol-lowering potential. The impact of NTU 101 and DSW on hamster gut microbiota was investigated side-by-side using denaturing gradient gel electrophoresis (DGGE) and metagenomic analysis in this study. These two cholesterol-lowering substances altered hamster cecal microbiota in a very different way with similar cholesterol lowering effects. Bacteroidetes was the only bacterial population that significantly correlated to host lipid profile (serum total cholesterol and serum low-density lipoprotein). Allobaculum and Clostridium XIVa were associated with beneficial effect of NTU 101. Parasutterella was only associated with consumption of DSW. The major bacterial taxa Akkermansia is associated with high-cholesterol diet but not host cholesterol level. This phenomenon suggested that cholesterol lowering effect is not necessarily linked to specific bacteria-host interaction, and the conclusion of causal relationships among bacterial abundance, diet, and host physiology should be more rigorously investigated. PMID- 27709287 TI - Biological treatment of actual petrochemical wastewater using anaerobic/anoxic/oxic process and the microbial diversity analysis. AB - A novel process integrating anaerobic hydrolysis-acidification (HA) and anoxic/oxic (A/O) reactors was developed to treat the actual petrochemical wastewater, which was operated for more than 8 months, the removal efficiency of COD and NH4+-N was monitored, and the microbial community was analyzed. The results showed that the effluent concentrations were maintained at around 99 and 1.3 mg/L, with the removal efficiency of 70.6 and 95.4 %, respectively at a total hydraulic retention time (HRT) of 20 h. The major pollutants in the influent were identified as hydrocarbons, aldehydes, heterocyclic matters, amines, alcohols, phenols, ketones, etc. by GC-MS analysis, while only heterocyclic compounds, ketones, and esters were detected in the effluent after HA-A/O treatment. Bacteria belonging to phyla Chloroflexi, Proteobacteria, and Bacteroidetes were highly enriched in the system. The predominant genera in HA, anoxic, and oxic tanks were Anaerolineaceae uncultured and Desulfobacter, Blastocatella and Anaerolineaceae uncultured, Saprospiraceae uncultured and Nitrosomonadaceae uncultured, respectively. The sulfate-reducing bacteria Desulfobacter, Desulfofustis and Desulfomicrobium were detected only in HA reactor. The ammonium oxidizing bacteria Nitrosomonadaceae and Nitrosomonas and nitrite-oxidizing bacteria Nitrospira were highly enriched in A/O reactor, which is consistent with the good nitrification performance. PMID- 27709288 TI - Heterologous expression of oxytetracycline biosynthetic gene cluster in Streptomyces venezuelae WVR2006 to improve production level and to alter fermentation process. AB - Heterologous expression is an important strategy to activate biosynthetic gene clusters of secondary metabolites. Here, it is employed to activate and manipulate the oxytetracycline (OTC) gene cluster and to alter OTC fermentation process. To achieve these goals, a fast-growing heterologous host Streptomyces venezuelae WVR2006 was rationally selected among several potential hosts. It shows rapid and dispersed growth and intrinsic high resistance to OTC. By manipulating the expression of two cluster-situated regulators (CSR) OtcR and OtrR and precursor supply, the OTC production level was significantly increased in this heterologous host from 75 to 431 mg/l only in 48 h, a level comparable to the native producer Streptomyces rimosus M4018 in 8 days. This work shows that S. venezuelae WVR2006 is a promising chassis for the production of secondary metabolites, and the engineered heterologous OTC producer has the potential to completely alter the fermentation process of OTC production. PMID- 27709289 TI - Enrichment of denitratating bacteria from a methylotrophic denitrifying culture. AB - Denitratation (nitrite produced from nitrate), has the potential applications in wastewater treatment by combining with ANAMMOX process. The occurrence of denitratation has been shown to be effected qualitatively by various parameters in the environment. A more quantitative understanding can be obtained using enrichment cultures in lab-scale experiments, yet information on the enrichment of functional microorganisms responsible for denitratation is lacking. In this study, a stable denitratation-dominated culture was obtained from methylotrophic denitrifying culture. The results showed that, besides the substitution of acetate for methanol, the lasting starvation following saturation of electron donor was another pivotal selection pressure that favored the growth of denitratating bacteria, which was supported by the distinctive physiological strategy involving the higher growth rate combining with larger poly hydroxybutyrate (PHB) accumulation at sufficient electron donor situation and then manage the stress of electron donor starvation by consumpiton of the PHB. High-throughput 16S rRNA gene sequencing analysis indicated that non methylotrophic Halomonas campisalis (48.1 %) and Halomonas campaniensis (30.4 %) dominated in the denitratating community. Moreover the denitratation was driven by the nitrate inhibiting the nirS transcription in the Halomonas species. PMID- 27709290 TI - Open versus laparoscopic approach for intestinal malrotation in infants and children: a systematic review and meta-analysis. AB - PURPOSE: Although the principles of the Ladd's procedure for intestinal malrotation in children have remained unchanged since its first description, in the era of minimally invasive surgery it is controversial whether laparoscopy is advantageous over open surgery. The aim of our study was to determine whether the surgical approach for the treatment of malrotation had an impact on patient outcome. METHODS: Using a defined strategy (PubMed, Cochrane, Embase and Web of Science MeSH headings), two investigators independently searched for studies comparing open versus laparoscopic Ladd's procedure in children. Case reports and opinion articles were excluded. Outcome measures included age at operation, time to full enteral feeding, length of hospital stay, and post-operative complications. Maneuvers were compared using Fisher's exact test and meta analysis was conducted using RevMan 5.3. Data are expressed as mean +/- SD. RESULTS: Of 308 abstracts screened, 49 full-text articles were analyzed and nine (all retrospective) met our search criteria. Selected articles included 1003 patients, of whom 744 (74 %) underwent open surgery and 259 (26 %) laparoscopy. Patients who had open surgery were younger (0.9 +/- 1.2 years) than those who underwent laparoscopy (2.6 +/- 3 years; p < 0.0001). Laparoscopy was converted to open Ladd's in 25.3 % patients. Laparoscopy was associated with faster full enteral feeding (1.5 +/- 0.3 days) in comparison to open surgery (4.6 +/- 0.1 days, p < 0.0001). Length of hospital stay was shorter in the laparoscopic group (5.9 +/- 4.3 days) than in the open group (11.2 +/- 6.7 days; p < 0.0001). Open surgery was associated with higher overall post-operative complication rate (21 %) than laparoscopy (8 %; p < 0.0001). Although there was no difference in the prevalence of post-operative bowel obstruction (open, n = 10 %; laparoscopy, n = 0 % p = 0.07), post-operative volvulus was more frequent in the laparoscopy group (3.5 %) than in the open group (1.4 %, p = 0.04). CONCLUSION: Comparative but non randomized studies indicate that laparoscopic Ladd's procedure is not commonly performed in young children. Although one third of laparoscopic procedures is converted to open surgery, laparoscopy is associated with shorter time to full enteral feeds and length of hospital stay. However, laparoscopic Ladd's procedure seems to have higher incidence of post-operative volvulus. Prospective randomized studies with long follow-up are needed to confirm present outcome data and determine the safety and effectiveness of the laparoscopic approach. PMID- 27709291 TI - Influence of Gender on Epidemiology and Clinical Manifestations of Sarcoidosis: A Population-Based Retrospective Cohort Study 1976-2013. AB - PURPOSE: The influence of ethnicity on epidemiology and clinical manifestations of sarcoidosis is well recognized. However, data on the role of sex are limited. METHODS: The current study utilized the resource of the Rochester Epidemiology Project to identify all residents of Olmsted County, Minnesota, United States, with new diagnosis of sarcoidosis from 1976 to 2013. Diagnosis was verified by medical record and histopathological report review. RESULTS: 345 incident cases of sarcoidosis were identified: 174 (50 %) were female and 171 (50 %) were male. The age at diagnosis was significantly higher among females than males (48.3 vs. 42.8 years; p < 0.001). Intra-thoracic disease was seen in the great majority of patients (98 % among females and 96 % among males; p = 0.50). However, pulmonary symptoms were significantly more frequent among males than females (51 vs. 36 %; p = 0.006). The frequency of individual extra-thoracic organ involvement was not significantly different between females and males except for cutaneous involvement and uveitis that were significantly more common among females (6 vs. 1 % for uveitis, p = 0.012 and 25 vs. 12 % for cutaneous involvement, p = 0.002). The frequency of elevate angiotensin-converting enzyme level and hypercalcemia was not significantly different between the two sexes. CONCLUSIONS: Females tended to be older at the age they developed sarcoidosis, and had more uveitis and cutaneous involvement than males. PMID- 27709292 TI - Acoustic analysis of snoring sounds recorded with a smartphone according to obstruction site in OSAS patients. AB - Snoring is a sign of increased upper airway resistance and is the most common symptom suggestive of obstructive sleep apnea. Acoustic analysis of snoring sounds is a non-invasive diagnostic technique and may provide a screening test that can determine the location of obstruction sites. We recorded snoring sounds according to obstruction level, measured by DISE, using a smartphone and focused on the analysis of formant frequencies. The study group comprised 32 male patients (mean age 42.9 years). The spectrogram pattern, intensity (dB), fundamental frequencies (F 0), and formant frequencies (F 1, F 2, and F 3) of the snoring sounds were analyzed for each subject. On spectrographic analysis, retropalatal level obstruction tended to produce sharp and regular peaks, while retrolingual level obstruction tended to show peaks with a gradual onset and decay. On formant frequency analysis, F 1 (retropalatal level vs. retrolingual level: 488.1 +/- 125.8 vs. 634.7 +/- 196.6 Hz) and F 2 (retropalatal level vs. retrolingual level: 1267.3 +/- 306.6 vs. 1723.7 +/- 550.0 Hz) of retrolingual level obstructions showed significantly higher values than retropalatal level obstruction (p < 0.05). This suggests that the upper airway is more severely obstructed with retrolingual level obstruction and that there is a greater change in tongue position. Acoustic analysis of snoring is a non-invasive diagnostic technique that can be easily applied at a relatively low cost. The analysis of formant frequencies will be a useful screening test for the prediction of occlusion sites. Moreover, smartphone can be effective for recording snoring sounds. PMID- 27709293 TI - Expression of Fas, FasL, caspase-8 and other factors of the extrinsic apoptotic pathway during the onset of interdigital tissue elimination. AB - Elimination of the interdigital web is considered to be the classical model for assessing apoptosis. So far, most of the molecules described in the process have been connected to the intrinsic (mitochondrial) pathway. The extrinsic (receptor mediated) apoptotic pathway has been rather neglected, although it is important in development, immunomodulation and cancer therapy. This work aimed to investigate factors of the extrinsic apoptotic machinery during interdigital regression with a focus on three crucial initiators: Fas, Fas ligand and caspase 8. Immunofluorescent analysis of mouse forelimb histological sections revealed abundant expression of these molecules prior to digit separation. Subsequent PCR Array analyses indicated the expression of several markers engaged in the extrinsic pathway. Between embryonic days 11 and 13, statistically significant increases in the expression of Fas and caspase-8 were observed, along with other molecules involved in the extrinsic apoptotic pathway such as Dapk1, Traf3, Tnsf12, Tnfrsf1A and Ripk1. These results demonstrate for the first time the presence of extrinsic apoptotic components in mouse limb development and indicate novel candidates in the molecular network accompanying the regression of interdigital tissue during digitalisation. PMID- 27709294 TI - Amputated limb by cerclage wire of femoral diaphyseal fracture: a case report. AB - An entrapment of the femoral artery by cerclage wiring is a rare complication after spiral diaphyseal femoral fractures. We report the case of an 82-year-old female treated by an antegrade intramedullary nailing and multiple cable augmentation, which was then complicated by injury to the femoral artery that resulted in ipsilateral leg necrosis and amputation. The entrapment was caused by direct belting by the cable and resulted in a total obstruction of the femoral artery. PMID- 27709295 TI - Topically applied manganese-porphyrins BMX-001 and BMX-010 display a significant anti-inflammatory response in a mouse model of allergic dermatitis. AB - In this study, we topically administered two antioxidant compounds, the manganese porphyrin-derivatives BMX-001 and BMX-010, in a mouse model of allergic dermatitis and compared the efficacy for reduction of itch and inflammation. In vitro effects of BMX-001 and BMX-010 on keratinocytes, bone marrow derived dendritic cells (BMDCs) and T-cells were initially analysed. For assessment of scratching behaviour, BMX-001 and BMX-010 (0.01 and 0.1 %) were topically applied 16 h and/or 1 h before compound 48/80 or toluene-2,4,-diisocyanate (TDI) challenge in a TDI induced mouse dermatitis model. Additionally, assessment of allergic skin inflammation was performed in a similar manner in the TDI model. Post-treatment ear thickness was measured 24 h after TDI challenge and compared to basal values. The mice were sacrificed and the ear auricle was removed for further analysis. In vitro, both BMX substances significantly inhibited cytokine production of keratinocytes as well as of BMDC and T-cell proliferation. Topical treatment with BMX cream resulted in a significant decrease in scratching behaviour in the compound 48/80 model, but not in the TDI model. Mice treated with BMX-001 and BMX-010 showed a moderate dose dependent decrease in ear thickness, and interestingly, the concentration of the cytokines IL-1beta and IL 4 in inflamed skin was reduced by 80-90 % by all treatment options. These first results suggest the potential benefit of a BMX-001 and BMX-010 cream for the treatment of allergic-inflammatory skin diseases. PMID- 27709296 TI - Validity of a perceptually-regulated step test protocol for assessing cardiorespiratory fitness in healthy adults. AB - PURPOSE: To determine whether maximal oxygen uptake (VO2max) could be predicted accurately and reliably from a 2-step, perceptually-regulated exercise test (PRET) in healthy adults. METHODS: Sixteen participants (31.7 +/- 11.3 years, 3 females) completed three PRETs (separated by 24-72 h) and one maximal, perceptually-regulated, graded exercise test (PRETmax) on a motorized treadmill. Oxygen uptake (VO2) and heart rate (HR) were recorded during each test. VO2 values for RPE range 9-15 were extrapolated to RPE 20 and age-predicted maximal HR (HRmax) using individual linear regression analysis to predict VO2max values compared to measured VO2max. RESULTS: VO2 and HR values were consistent between each of four RPE levels of the PRET. ICC values ranged between 0.76 and 0.85. Predicted VO2max from both methods were lower than measured VO2max (p < 0.01). Limits of agreement (LoA) for measured (41.4 +/- 5.3 ml kg-1 min-1) versus predicted VO2max from each of the three PRETs using RPE20 were -1.2 +/- 15.6, 1.0 +/- 7.2 and -2.1 +/- 5.5 and for HRmax were -1.8 +/- 4.2; -2.6 +/- 4.2 and 2.4 +/- 4.4 ml kg-1 min-1 for PRET 1, 2 and 3, respectively. CONCLUSIONS: The step PRET elicited significant and reliable increases in VO2 across the four RPE levels, but under-estimated treadmill VO2max. However, there was better agreement between measured and predicted VO2max when extrapolated to HRmax. As evidence indicates the underestimation of VO2max is explained by the difference in the mode of exercise, the step PRET provides a simple and convenient test of cardiorespiratory fitness. PMID- 27709297 TI - Silicate calculi, a rare cause of kidney stones in children. AB - BACKGROUND: Urinary silicate calculi in humans are extremely rare. Reported cases of silicate calculi are mostly documented in adults and are commonly related to an excessive intake of magnesium trisilicate in food or drugs. Published studies on the presence of silicate calculi in children are scarce. CASES: Three cases of silicate kidney stones without prior silicate intake are reported. Two patients underwent surgical treatment, and the third patient was treated using conservative methods. Urinalysis revealed no underlying metabolic abnormalities. Analyses revealed that silicate was the major component of the stones. CONCLUSION: Siliceous deposits in urinary stones may be more common than anticipated, and the underlying pathophysiology remains to be clarified. PMID- 27709298 TI - Removal of extracellular coat from giant sperm in female receptacle induces sperm motility in Mytilocypris mytiloides (Cyprididae, Ostracoda, Crustacea). AB - Previous studies of cypridoidean ostracods have noted that (1) their giant spermatozoa are immotile inside the male, (2) these spermatozoa are motile in the female seminal receptacle and (3) these receptacles are often filled with empty sperm coats. Such findings have led previous authors to hypothesize that sperm must shed their coats in the female receptacle to become motile. We present light and electron microscopy results and video recordings of mating experiments with virgin specimens of Mytilocypris mytiloides. We show that the empty sperm coats frequently found in the female receptacles are not the result of sperm molting but are the resistant inner coats of exhausted sperm not used for egg fertilization. In contrast, we show that an outer granular coating material is successively removed from the sperm while resident inside the female receptacles before first oviposition occurs. During this period, previously immotile sperm gain motility, showing strong movement shortly before first oviposition takes place. By correlation of these phenomena, we suggest that dissolution of the outer coat material is required for motility to develop. PMID- 27709299 TI - A practical guide for the identification of major sulcogyral structures of the human cortex. AB - The precise sulcogyral localization of cortical lesions is mandatory to improve communication between practitioners and to predict and prevent post-operative deficits. This process, which assumes a good knowledge of the cortex anatomy and a systematic analysis of images, is, nevertheless, sometimes neglected in the neurological and neurosurgical training. This didactic paper proposes a brief overview of the sulcogyral anatomy, using conventional MR-slices, and also reconstructions of the cortical surface after a more or less extended inflation process. This method simplifies the cortical anatomy by removing part of the cortical complexity induced by the folding process, and makes it more understandable. We then reviewed several methods for localizing cortical structures, and proposed a three-step identification: after localizing the lateral, medial or ventro-basal aspect of the hemisphere (step 1), the main interlobar sulci were located to limit the lobes (step 2). Finally, intralobar sulci and gyri were identified (step 3) thanks to the same set of rules. This paper does not propose any new identification method but should be regarded as a set of practical guidelines, useful in daily clinical practice, for detecting the main sulci and gyri of the human cortex. PMID- 27709300 TI - Methamphetamine self-administration modulates glutamate neurophysiology. AB - World-wide methamphetamine (meth) use is increasing at a rapid rate; therefore, it has become increasingly important to understand the synaptic changes and neural mechanisms affected by drug exposure. In rodents, 6-h access to contingent meth results in an escalation of drug intake and impaired cognitive sequelae typically associated with changes within the corticostriatal circuitry. There is a dearth of knowledge regarding the underlying physiological changes within this circuit following meth self-administration. We assessed pre- and postsynaptic changes in glutamate transmission in the medial prefrontal cortex (mPFC) and nucleus accumbens (NAc) following daily 6-h meth self-administration. In the mPFC, meth caused postsynaptic adaptations in ionotropic glutamate receptor distribution and function, expressed as a decrease in AMPA/NMDA ratio. This change was driven by an increase in NMDA receptor currents and an increase in GluN2B surface expression. In the NAc, meth decreased the paired-pulse ratio and increased the frequency of spontaneous excitatory postsynaptic currents with no indication of postsynaptic changes. These changes in mPFC synapses and NAc activity begin to characterize the impact of meth on the corticostriatal circuitry.

AB - Extra-ischaemic (remote) brain heamorrhages after thrombolysis for ischaemic stroke occur in less than 3 % of treated patients, but it worsens prognosis. Little attention has been paid to the location of the haematomas. Among 12 patients with remote brain haemorrhage after thrombolysis, we report three patients with haemorrhage in the cerebellar vermis (25 %), with poor outcome. Previous hypertensive vasculopathy is deemed to be the most plausible cause. PMID- 27709304 TI - Differences in the phenotypic effects of mutations in homologous MrpA and MrpD subunits of the multi-subunit Mrp-type Na+/H+ antiporter. AB - Mrp antiporters are the sole antiporters in the Cation/Proton Antiporter 3 family of transporter databases because of their unusual structural complexity, 6-7 hydrophobic proteins that function as a hetero-oligomeric complex. The two largest and homologous subunits, MrpA and MrpD, are essential for antiport activity and have direct roles in ion transport. They also show striking homology with proton-conducting, membrane-embedded Nuo subunits of respiratory chain complex I of bacteria, e.g., Escherichia coli. MrpA has the closest homology to the complex I NuoL subunit and MrpD has the closest homology to the complex I NuoM and N subunits. Here, introduction of mutations in MrpD, in residues that are also present in MrpA, led to defects in antiport function and/or complex formation. No significant phenotypes were detected in strains with mutations in corresponding residues of MrpA, but site-directed changes in the C-terminal region of MrpA had profound effects, showing that the MrpA C-terminal region has indispensable roles in antiport function. The results are consistent with a divergence in adaptations that support the roles of MrpA and MrpD in secondary antiport, as compared to later adaptations supporting homologs in primary proton pumping by the respiratory chain complex I. PMID- 27709303 TI - Antarctic strict anaerobic microbiota from Deschampsia antarctica vascular plants rhizosphere reveals high ecology and biotechnology relevance. AB - The Antarctic soil microbial community has a crucial role in the growth and stabilization of higher organisms, such as vascular plants. Analysis of the soil microbiota composition in that extreme environmental condition is crucial to understand the ecological importance and biotechnological potential. We evaluated the efficiency of isolation and abundance of strict anaerobes in the vascular plant Deschampsia antarctica rhizosphere collected in the Antarctic's Admiralty Bay and associated biodiversity to metabolic perspective and enzymatic activity. Using anaerobic cultivation methods, we identified and isolated a range of microbial taxa whose abundance was associated with Plant Growth-Promoting Bacteria (PGPB) and presences were exclusively endemic to the Antarctic continent. Firmicutes was the most abundant phylum (73 %), with the genus Clostridium found as the most isolated taxa. Here, we describe two soil treatments (oxygen gradient and heat shock) and 27 physicochemical culture conditions were able to increase the diversity of anaerobic bacteria isolates. Heat shock treatment allowed to isolate a high percentage of new species (63.63 %), as well as isolation of species with high enzymatic activity (80.77 %), which would have potential industry application. Our findings contribute to the understanding of the role of anaerobic microbes regarding ecology, evolutionary, and biotechnological features essential to the Antarctic ecosystem. PMID- 27709305 TI - Analysis of the safety evaluation for premarketing clinical trials of hemodialyzer and of postmarketing safety reports of hemodialyzer in Japan and the US: insights into the construction of a sophisticated premarketing evaluation. AB - Our aim was to conduct a scoping review of the regulations for hemodialyzers in the safety evaluation in Japan and the United States, and to evaluate the criteria for premarketing clinical trials and postmarketing safety reports to inform the development of a sophisticated premarketing evaluation in Japan. Regulations for approval of hemodialyzers were identified from the databases of the Ministry of Health, Labor and Welfare in Japan and the Federal Drug Agency (FDA) in the United States (US). The criteria for premarket clinical trials and postmarketing safety reports were evaluated for both countries. Standards in Japan required evaluation of blood compatibility and reporting of acute adverse effects by a premarketing clinical trial in 6 of 86 applications with semipermeable membrane materials deemed to be different to those of previously approved devices from 1983 to 31 August 2015. By comparison, the clinical trial was required in one of 545 approvals in the US from 1976 to 29 January 2016, but blood compatibility was not the point. All postmarketing adverse effects identified in Japan were included in the set of 'warnings'. The more stringent requirements for evaluation of blood compatibility and acute adverse effects in Japan seemed to be related to differences in the history of quality management systems for medical devices between the two countries. This study revealed that there were differences between Japan and the US in requiring the premarketing clinical trials for the hemodialyzers. Our findings could be useful for constructing sophisticated premarketing safety evaluation. PMID- 27709306 TI - Axillo-iliac arteriovenous hemodialysis graft creation with an early cannulation device. AB - Exhaustion of superficial veins coupled with the presence of intrathoracic central venous occlusions remains a significant obstacle for hemodialysis access creation; complex arteriovenous graft (AVG) configurations have been described. The axillary-iliac AVG was first reported in 1987, and few authors have explored this access. We evaluated our experience with this AVG configuration utilizing the early cannulation (EC) graft FlixeneTM (Atrium TM, Hudson, NH, USA). Eight patients (75 % men; mean age 37 +/- 10 years) with End-Stage Renal Disease (ESRD) underwent axillo-iliac AVG creation with FlixeneTM grafts; all had exhausted peripheral veins, occluded thoracic central veins, and inadequate femoral veins. Inflow from the axillary artery and outflow in iliocaval system was assessed prior to access creation. An axillary-to-common iliac AVG was constructed using a 6 mm (mm) EC graft and tunneled in the chest and abdominal wall. Eight grafts were implanted; all were patent after placement. Seven (88 %) were successfully used for hemodialysis within 72 h and one (12 %) within 96. During the mean follow-up of 6 months, 5 (62 %) patients underwent thrombectomy, 1 (12 %) of them had balloon angioplasty at the vein anastomosis, and 2 (25 %) grafts were removed secondary to infection. The remaining grafts are still functioning. Complications as high-output heart failure, steal syndrome and venous hypertension were not observed. Construction of axillo-iliac AVG with EC grafts in the setting of exhausted veins, occluded intrathoracic central veins and hostile groins, is a viable arteriovenous access alternative while avoiding central venous catheters. PMID- 27709307 TI - Validation of a predictive model for identifying febrile young infants with altered urinalysis at low risk of invasive bacterial infection. AB - In 2015, a predictive model for invasive bacterial infection (IBI) in febrile young infants with altered urine dipstick was published. The aim of this study was to externally validate a previously published set of low risk criteria for invasive bacterial infection in febrile young infants with altered urine dipstick. Retrospective multicenter study including nine Spanish hospitals. Febrile infants <=90 days old with altered urinalysis (presence of leukocyturia and/or nitrituria) were included. According to our predictive model, an infant is classified as low-risk for IBI when meeting all the following: appearing well at arrival to the emergency department, being >21 days old, having a procalcitonin value <0.5 ng/mL and a C-reactive protein value <20 mg/L. IBI was considered as secondary to urinary tract infection if the same pathogen was isolated in the urine culture and in the blood or cerebrospinal fluid culture. A total of 391 patients with altered urine dipstick were included. Thirty (7.7 %) of them developed an IBI, with 26 (86.7 %) of them secondary to UTI. Prevalence of IBI was 2/104 (1.9 %; CI 95% 0.5-6.7) among low-risk patients vs 28/287 (9.7 %; CI 95% 6.8-13.7) among high-risk patients (p < 0.05). Sensitivity of the model was 93.3 % (CI 95% 78.7-98.2) and negative predictive value was 98.1 % (93.3-99.4). Although our predictive model was shown to be less accurate in the validation cohort, it still showed a good discriminatory ability to detect IBI. Larger prospective external validation studies, taking into account fever duration as well as the role of ED observation, should be undertaken before its implementation into clinical practice.

AB - Variable therapy of asthma is not sufficient yet to achieve good asthma control. Therapy decision requires serial investigations. Low-level laser acupuncture is a suitable non-invasive modality of complementary medicine. The exhaled breath condensate (EBC) is easy and useful to evaluate the efficacy of drugs or novel therapy. This study aimed to evaluate the effectiveness of low-level laser biostimulation of acupuncture points on asthma improvement in children. Forty eight asthmatic children were subdivided into case (laser) group, which received 12 direct contact low-power laser acupuncture sessions (three sessions/week) on specific traditional Chinese acupuncture points for bronchial asthma, and control asthmatic group, which received sham laser acupuncture on the same acupoints and number of sessions of the case (laser) group. Low-power Multichannel Aculas-AM laser (grade II) of wave length 780 nm, output power 800 mw, and beam spot size 0.1 cm2 with continuous mode was used. Eighteen acupoints were stimulated for 2 min, giving energy of 9.6 J/cm2/acupoint. The total session time was 3 min. Both groups were evaluated pre- and post-laser acupuncture intervention by recording levels of asthma control, pulmonary function, and EBC nitric oxide. In the case (laser) group, 91.7 % of patients experienced an improvement in the level of asthma control versus 25 % in the control group (p < 0.001). This was associated with a significant decrease of the breath condensate FENO concentration (p < 0.001) and significant increase of spirometry parameters (p < 0.001) in the case (laser) group. Application of laser acupuncture treatment given with conventional therapy can effectively improve bronchial asthma more than prescription of medications alone could.

AB - Batrachochytrium salamandrivorans (Bsal) is a virulent fungal pathogen that infects salamanders. It is implicated in the recent collapse of several populations of fire salamanders in Europe. This pathogen seems much like that of its sister species, Batrachochytrium dendrobatidis (Bd), the agent responsible for anuran extinctions and extirpations worldwide, and is considered to be an emerging global threat to salamander communities. Bsal thrives at temperatures found in many mountainous regions rich in salamander species; because of this, we have screened specimens of salamanders representing 17 species inhabiting mountain ranges in three continents: The Smoky Mountains, the Swiss Alps, and the Peruvian Andes. We screened 509 salamanders, with 192 representing New World salamanders that were never tested for Bsal previously. Bsal was not detected, and Bd was mostly present at low prevalence except for one site in the Andes. PMID- 27709309 TI - Suitable Concentrations of Uric Acid Can Reduce Cell Death in Models of OGD and Cerebral Ischemia-Reperfusion Injury. AB - Cerebral infarction (CI) is a common clinical cerebrovascular disease, and to explore the pathophysiological mechanisms and seek effective treatment means are the hotspot and difficult point in medical research nowadays. Numerous studies have confirmed that uric acid plays an important role in CI, but the mechanism has not yet been clarified. When treating HT22 and BV-2 cells with different concentrations of uric acid, uric acid below 450 MUM does not have significant effect on cell viability, but uric acid more than 500 MUM can significantly inhibit cell viability. After establishing models of OGD (oxygen-glucose deprivation) with HT22 and BV-2 cells, uric acid at a low concentration (50 MUM) cannot improve cell viability and apoptosis, and Reactive oxygen species (ROS) levels during OGD/reoxygenation; a suitable concentration (300 MUM) of uric acid can significantly improve cell viability and apoptosis, and reduce ROS production during OGD/reoxygenation; but a high concentration (1000 MUM) of uric acid can further reduce cell viability and enhance ROS production. After establishing middle cerebral artery occlusion of male rats with suture method, damage and increase of ROS production in brain tissue could be seen, and after adding suitable concentration of uric acid, the degree of brain damage and ROS production was reduced. Therefore, different concentrations of uric acid should have different effect, and suitable concentrations of uric acid have neuroprotective effect, and this finding may provide guidance for study on the clinical curative effect of uric acid. PMID- 27709311 TI - Transmission Dynamics of the West Nile Virus in Mosquito Vector Populations under the Influence of Weather Factors in the Danube Delta, Romania. AB - Mosquitoes were collected in the Danube Delta during the active seasons of 2011 2013. For Culex spp. mosquitoes, the abundance was calculated. Culex pipiens (sensu lato), (s.l.) and Culex modestus pools were tested for the presence of West Nile virus (WNV) genome, and the maximum likelihood of the infection rate was established. Mean daily temperatures and precipitation were obtained for the closest meteorological station. A negative binominal model was used to evaluate linkages between the temperature/precipitation and mosquito population size. A zero-inflated negative binomial model was used to test the relationship between the temperature and the infection rate. A single complex model for infection rate prediction was also used. The linkages were calculated for lag 0 and for 10 days earlier (lag 1), 20 days earlier (lag 2), and 30 days earlier (lag 3). Significant positive linkages (P < 0.001) were detected between temperature and mosquito population size for lag 1, lag 2, and lag 3. The linkages between temperature and infection rates were positive and significant for lag 2 and lag 3. Negative significant (P < 0.001) results were detected between precipitation and infection rates for lags 1, 2, and 3. The complex model showed that the best predictors for infection rate are the temperature, 20 days earlier (positive linkage) and the precipitation, 30 days earlier (negative linkage). Positive temperature anomalies in spring and summer and rainfall decrease contributed to the increase in the Culex spp. abundance and accelerated the WNV amplification in mosquito vector populations in the following weeks. PMID- 27709312 TI - Pathways between physical activity and quality of life in African-American breast cancer survivors. AB - INTRODUCTION: Several studies have indicated that the relationship between physical activity and quality of life is not directed but mediated through various pathways. The purpose of this study was to assess the role of cancer related fatigue, disability, and functional status as potential mediators in African-American breast cancer survivors. METHODS: African-American breast cancer survivors (N = 135, mean age = 63) aged 55 years and older participated in a web based survey consisting of measures assessing physical activity, functional status, cancer-related fatigue, disability, quality of life, and sociodemographic and medical characteristics. Structural equation modeling was used to assess the structural relationships among the constructs. RESULTS: The initial structural model fit the data and revealed a significant relationship between physical activity and quality of life (beta = 0.34, P < 0.01). Subsequent structural models with proposed complementary and mediating paths of fatigue, function, and disability fit the data. The adjusted model indicated that physical activity was no longer associated with quality of life (beta = 0.11, P > 0.05) and mediated through pathways of functional status and fatigue (total beta = 0.16, P < 0.01). The final adjusted model accounted for 32 % of the variance in quality of life. CONCLUSION: Our data suggest that physical activity may be indirectly related to quality of life through pathways consisting of fatigue and functional status. Further longitudinal studies are needed to test the pathways through which varying levels of physical activity influence cancer-related and quality of life outcomes in minority cancer survivors. PMID- 27709313 TI - A randomized, multi-center, open-label, phase III study of once-per-cycle DA 3031, a pegylated G-CSF, in comparison with daily filgrastim in patients receiving TAC chemotherapy for breast cancer. AB - PURPOSE: This multi-center, randomized, phase III study was conducted to demonstrate the non-inferiority of DA-3031 compared with daily filgrastim in patients during the first cycle of chemotherapy for breast cancer in terms of the duration of severe neutropenia (DSN). METHODS: Seventy-four patients with breast cancer who were receiving combination chemotherapy with docetaxel, doxorubicin, and cyclophosphamide (TAC) were enrolled. All participants were randomized to receive either daily subcutaneous injections of filgrastim 100 MUg/m2/day for up to 10 days or a single subcutaneous injection of DA-3031 at fixed doses of 6 mg on day 2 of each chemotherapy cycle. RESULTS: The mean duration of grade 4 (G4) neutropenia in cycle 1 was 2.08 +/- 0.85 days for the filgrastim group and 2.28 +/- 1.14 days for the DA-3031 group. The difference between groups was 0.2 +/- 1.10 days (95 % confidence interval (CI) = -0.26, 0.66), which supported non inferiority. No statistically significant differences were observed in nadir absolute neutrophil count (ANC) (154.34/mm3 and 161.75/mm3 for the filgrastim and DA-3031 groups, respectively; P = 0.8414) or in time to ANC recovery (10.03 +/- 0.75 and 9.83 +/- 1.56 days in the filgrastim and DA-3031 groups, respectively; P = 0.0611) during cycle 1. Serious AEs occurred in six (15.8 %) patients receiving filgrastim and in ten (27.8 %) patients receiving DA-3031; however, none was determined to be related to the study drug. CONCLUSIONS: DA-3031 and daily filgrastim are similar in regard to DSN and safety in breast cancer patients receiving TAC chemotherapy. PMID- 27709314 TI - A simple and robust protocol for high-yield expression of perdeuterated proteins in Escherichia coli grown in shaker flasks. AB - We present a simple, convenient and robust protocol for expressing perdeuterated proteins in E. coli BL21(DE3) cells in shaker flasks that reduces D2O usage tenfold and d7-glucose usage by 30 %. Using a modified M9 medium and optimized growth conditions, we were able to grow cells in linear log phase to an OD600 of up to 10. Inducing the cells with isopropyl beta-D-1-thiogalactopyranoside at an OD600 of 10, instead of less than 1, enabled us to increase the cell mass tenfold per unit volume of cell culture. We show that protein expression levels per cell are the same when induced at an OD600 between 1 and 10 under these growth conditions. Thus, our new protocol can increase protein yield per unit volume of cell culture tenfold. Adaptation of E. coli from H2O-based to D2O-based medium is also key for ensuring high levels of protein expression in D2O. We find that a simple three-step adaptation approach-Luria-Bertani (LB) medium in H2O to LB in D2O to modified-M9 medium in D2O is both simple and reliable. The method increases the yield of perdeuterated proteins by up to tenfold using commonly available air shakers without any requirement for specialized fermentation equipment. PMID- 27709315 TI - Inhibition of IRF8 Negatively Regulates Macrophage Function and Impairs Cutaneous Wound Healing. AB - The inflammatory response is essential for normal cutaneous wound healing. Macrophages, as critical inflammatory cells, coordinate inflammation and angiogenesis phases during wound healing. It has been reported that the transcription factor interferon regulatory factor 8 (IRF8), a member of the IRF family, plays a critical role in the development and function of macrophages and is associated with inflammation. However, the role of IRF8 in cutaneous wound healing and its underlying mechanism remain elusive. Through immunohistochemical (IHC) staining, we showed that IRF8 is involved in the wound repair process in mice and patients. Furthermore, we ascertain that the repression of IRF8 by small interfering RNA (siRNA) leads to delayed wound healing. To explore the mechanism by which IRF8 impacts wound healing, we observed its effect on macrophage-related mediators by IHC or real-time PCR. The results demonstrated that the inhibition of IRF8 decreases the mRNA expression of inflammatory mediators associated with M1 macrophage (il-1b, il-6, inos, and tnf-a) but no impact on M2 macrophage related mediators (arg-1, mrc-1, and il-10) and the number of macrophages in the wounds. Furthermore, the inhibition of IRF8 induced apoptosis in the wounds. In summary, this study demonstrates that the down-regulation of IRF8 in the wound leads to impaired wound healing possibly through the regulation of macrophage function and apoptosis in skin wound. PMID- 27709316 TI - Coumestrol Counteracts Interleukin-1beta-Induced Catabolic Effects by Suppressing Inflammation in Primary Rat Chondrocytes. AB - In the present study, we investigated the anti-catabolic effects of coumestrol, a phytoestrogen derived from herbal plants, against interleukin-1beta-induced cartilage degeneration in primary rat chondrocytes and articular cartilage. Coumestrol did not affect the viability of human normal oral keratinocytes and primary rat chondrocytes treated for 24 h and 21 days, respectively. Although coumestrol did not significantly increase the proteoglycan contents in long-term culture, it abolished the interleukin-1beta-induced loss of proteoglycans in primary rat chondrocytes and knee articular cartilage. Furthermore, coumestrol suppressed the expression of matrix-degrading enzymes such as matrix metalloproteinase-13, -3, and -1 in primary rat chondrocytes stimulated with interleukin-1beta. Moreover, the expression of catabolic factors such as nitric oxide synthase, cyclooxygenase-2, prostaglandin E2, and inflammatory cytokines in interleukin-1beta-stimulated primary rat chondrocytes was suppressed by coumestrol. In summary, these results indicate that coumestrol counteracts the catabolic effects induced by interleukin-1beta through the suppression of inflammation. Therefore, based on its biological activity and safety profile, coumestrol could be used as a potential anti-catabolic biomaterial for osteoarthritis. PMID- 27709317 TI - Docking-undocking combination applied to the D3R Grand Challenge 2015. AB - Novel methods for drug discovery are constantly under development and independent exercises to test and validate them for different goals are extremely useful. The drug discovery data resource (D3R) Grand Challenge 2015 offers an excellent opportunity as an external assessment and validation experiment for Computer Aided Drug Discovery methods. The challenge comprises two protein targets and prediction tests: binding mode and ligand ranking. We have faced both of them with the same strategy: pharmacophore-guided docking followed by dynamic undocking (a new method tested experimentally here) and, where possible, critical assessment of the results based on pre-existing information. In spite of using methods that are qualitative in nature, our results for binding mode and ligand ranking were amongst the best on Hsp90. Results for MAP4K4 were less positive and we track the different performance across systems to the level of previous knowledge about accessible conformational states. We conclude that docking is quite effective if supplemented by dynamic undocking and empirical information (e.g. binding hot spots, productive protein conformations). This setup is well suited for virtual screening, a frequent application that was not explicitly tested in this edition of the D3R Grand Challenge 2015. Protein flexibility remains as the main cause for hard failures. PMID- 27709318 TI - Self-Assembly of Colloidal Photonic Crystals of PS@PNIPAM Nanoparticles and Temperature-Responsive Tunable Fluorescence. AB - A strategy for significantly enhancing fluorescence is developed based on the coupling of optical properties of colloidal photonic crystals (CPCs) with responsive microgel. In this paper, thermoresponsive microgel PNIPAM was employed for the fabrication of core-shell structure. The core-shell PS@PNIPAM nanoparticles (NPs) are then assembled to CPCs by a vertical deposition method. Subsequently, the novel functional material (RhB/CPCs) can be prepared by depositing fluorescent dye molecules (RhB) on the top of PS@PNIPAM CPCs. We obtained an increase in the fluorescent intensity up to 15-fold and 22-fold compared with RhB on the glass slid and the uneven film. Due to the unique responsive shrinking properties of PNIPAM shell, the amplifying fluorescence behavior of CPCs can be well tuned by varying the temperature. In contrast to RhB on the glass slid, a 15-fold and 12-fold fluorescence enhancement can be observed when the temperature of RhB/CPCs was 20 degrees C and 50 degrees C, respectively. The mechanism on enhancement fluorescence of tunable CPCs can be achieved by measurements of thermoresponsive properties. The results indicate that the responsive fluorescence-amplifying method based on CPCs made with responsive core-shell NPs has a potential application for the development of efficient fluorescence sensors. PMID- 27709319 TI - Evaluation of HeartSmarts, a Faith-Based Cardiovascular Health Education Program. AB - In order to effectively address cardiovascular disease among African Americans, evidence-based health information must be disseminated within a context aligned with the values and beliefs of the population. Faith-based organizations play a critical role in meeting the religious and spiritual needs of many African Americans. Additionally, faith-based organizations can be effective in health promotion. A manual was created by incorporating biblical scriptures relating to health messages drawn from existing health manuals oriented toward African Americans. Lay health educators active in their churches participated in a 12 week training to learn the basics of cardiovascular disease and methods for delivering the program to their congregations' members. After the completion of the training, these lay health educators recruited participants from their respective churches and administered their own 12-week HeartSmarts program. Measurements of participants' systolic and diastolic blood pressure (mmHg), height (in.), weight (lbs.), and waist circumference (in.) were taken, and cardiovascular disease knowledge assessments (based on 20 open-ended questions) were administered at the start and end of the 12-week programs. Fourteen predominantly African American churches in NYC participated. Of the 221 participants, 199 completed the program. There were significant reductions in pretest and posttest total participant averages for systolic BP (4.48 mmHg, p < 0.001), diastolic BP (3.38 mmHg, p < 0.001), weight (3lbs., p = 0.001), and BMI (0.46, p = 0.001). Cardiovascular disease health assessment scores had an average increase of 12.74 correct responses (p < 0.001). The HeartSmarts program may be an effective ecumenical and cultural model for disseminating health messages and reducing cardiovascular risk among African Americans. PMID- 27709320 TI - ZmDof3, a maize endosperm-specific Dof protein gene, regulates starch accumulation and aleurone development in maize endosperm. AB - KEY MESSAGE: To explore the function of Dof transcription factors during kernel development in maize, we first identified Dof genes in the maize genome. We found that ZmDof3 was exclusively expressed in the endosperm of maize kernel and had the features of a Dof transcription factor. Suppression of ZmDof3 resulted in a defective kernel phenotype with reduced starch content and a partially patchy aleurone layer. The expression levels of starch synthesis-related genes and aleurone differentiation-associated genes were down-regulated in ZmDof3 knockdown kernels, indicating that ZmDof3 plays an important role in maize endosperm development. The maize endosperm, occupying a large proportion of the kernel, plays an important role in seed development and germination. Current knowledge regarding the regulation of endosperm development is limited. Dof proteins, a family of plant-specific transcription factors, play critical roles in diverse biological processes. In this study, an endosperm-specific Dof protein gene, ZmDof3, was identified in maize through genome-wide screening. Suppression of ZmDof3 resulted in a defective kernel phenotype. The endosperm of ZmDof3 knockdown kernels was loosely packed with irregular starch granules observed by electronic microscope. Through genome-wide expression profiling, we found that down-regulated genes were enriched in GO terms related to carbohydrate metabolism. Moreover, ZmDof3 could bind to the Dof core element in the promoter of starch biosynthesis genes Du1 and Su2 in vitro and in vivo. In addition, the aleurone at local position in mature ZmDof3 knockdown kernels varied from one to three layers, which consisted of smaller and irregular cells. Further analyses showed that knockdown of ZmDof3 reduced the expression of Nkd1, which is involved in aleurone cell differentiation, and that ZmDof3 could bind to the Dof core element in the Nkd1 promoter. Our study reveals that ZmDof3 functions in maize endosperm development as a positive regulator in the signaling system controlling starch accumulation and aleurone development.

AB - Guaiac resin, extracted from the heartwood of Guaiacum officinale L. or G. sanctum L., is speculated to have anti-inflammatory effects. Lignans were purified from guaiac resin (also known as gum guaiacum) by monitoring the nitric oxide (NO) production in rat hepatocytes treated with an inflammatory cytokine interleukin-1beta (IL-1beta). Six lignans were purified from guaiac resin and identified as: dehydroguaiaretic acid (1), (+)-trans-1,2-dihydrodehydroguaiaretic acid (2), furoguaiaoxidin (3), meso-dihydroguaiaretic acid (4), furoguaiacin (i.e., alpha-guaiaconic acid) (5), and nectandrin B (6). To our knowledge, this is the first time that 1 has been isolated from guaiac resin as a non-derivative. Compounds 2 and 6 were first found in guaiac resin. Compound 3 was first isolated from a natural source as a non-derivative. Furthermore, 1-6 significantly suppressed NO production in IL-1beta-treated hepatocytes. Because anti inflammatory compounds suppress NO production, this system is often used to measure the anti-inflammatory effects of Kampo drugs and herbal constituents. The NO-suppressing activity of the six lignans isolated in this study indicates that guaiac resin has anti-inflammatory effects and that these lignans may be responsible for the anti-inflammatory effects of guaiac resin. PMID- 27709322 TI - Potential drug interactions with dietary and herbal supplements during hospitalization. AB - Dietary and herbal supplements (DHS) are widely used in the general population, including during hospitalization. Yet, their potential interactions with prescription drugs have seldom been delineated among inpatients. We aimed to evaluate potentially dangerous interactions of DHS with prescribed medications among inpatients. This was a cross-sectional prospective study involving a cohort of patients hospitalized in 12 departments of a public academic medical center (Bnai Zion Medical Center, Haifa, Israel) from 2009 to 2014. DHS users were determined via a questionnaire. The Natural Medicine database was used to search for potential DHS-drug interactions for identified DHS, and the clinical significance was evaluated using Lexi-interact online interaction analysis. Medical files were assessed for documentation of DHS use. Univariate and multivariate logistic regression analyses were used to characterize potential risk factors for DHS-drug interactions. Of 927 patients consenting to answer the questionnaire, 458 (49 %) reported DHS use. Of these, 215 (47 %) had at least one potential interaction during hospitalization (759 interactions). Of these interactions, 116 (15 %) were potentially clinically significant. Older age [OR = 1.02 (1.01-1.04), p = 0.002], males [OR = 2.11 (1.35-3.29), p = 0.001] and increased number of used DHS [OR = 4.28 (2.28-8.03), p < 0.001] or drugs [OR = 1.95 (1.17-3.26), p = 0.011] were associated with potential interactions in DHS users. Physicians documented only 16.5 % of DHS involved in these interactions in patients' medical files. In conclusion, a substantial number of inpatients use DHS with potential interactions with concomitant medications. Medical staff should be aware of this, question patients on DHS usage and check for such interactions.

PMID- 27709324 TI - Comparison of mid-term clinical outcomes between on-label and off-label use of rotational atherectomy. AB - While rotational atherectomy (RA) is used for complex lesions in percutaneous coronary intervention, there are several contraindications such as unprotected left main stenosis or left ventricular dysfunction. We previously reported that the incidence of in-hospital complications was significantly greater in off-label as compared to on-label use RA. However, the mid-term clinical outcomes between off-label and on-label RA have not been investigated. The purpose of this study was to compare the mid-term clinical outcomes between off-label (n = 156) and on label RA (n = 94). The primary endpoint was the incidence of major adverse cardiovascular events (MACE) defined as the composite of ischemia-driven target vessel revascularization (TVR), non-fatal MI, and all-cause death. We also identified 154 patients who underwent RA and follow-up angiography within 1 year, and compared quantitative coronary analysis between the off-label group (n = 96) and on-label group (n = 58). There was no significant difference in late luminal loss between the groups (0.03 +/- 0.53 mm in the off-label and -0.05 +/- 0.44 mm in the on-label groups, P = 0.57). However, the incidence of MACE was less in the on-label group (3.2 %) as compared to the off-label group (9.0 %) without reaching statistical significance (P = 0.08). In conclusion, mid-term clinical outcomes tended to be worse in the off-label group than in the on-label group. We may have to follow-up the patient who underwent off-label RA more carefully than the patient who underwent on-label RA. PMID- 27709326 TI - Blocking the flow of propionate into TCA cycle through a mutB knockout leads to a significant increase of erythromycin production by an industrial strain of Saccharopolyspora erythraea. AB - A high erythromycin producing mutant strain Saccharopolyspora erythraea HL3168 E3 DeltamutB was constructed by deleting mutB (SACE_5639) gene encoding the beta subunit of methylmalonyl-CoA mutase of an industrial strain of S. erythraea HL3168 E3. Industrial media and process control strategies were adopted in a 5 L bioreactor for characterizing the physiological parameters. The total erythromycin titer and erythromycin A concentration in mutant were 46.9 (12740.5 MUg/mL) and 64.9 % (8094.4 MUg/mL) higher than those in original strain, respectively, which were comparable to industrial erythromycin production. The specific glucose and n-propanol consumption rates were increased by 52.4 and 39.8 %, respectively. During the rapid erythromycin synthesis phase, the yield of erythromycin on n-propanol also increased from 24.3 % in control group to 66.9 % in mutant group. Meanwhile, the specific formation rates of methylmalonyl-CoA and propionyl-CoA, two crucial precursors for erythromycin synthesis, were 1.89- and 2.02-folds higher in the mutant strain, respectively.

PMID- 27709325 TI - Prediction of 1-year clinical outcomes using the SYNTAX score in patients with prior heart failure undergoing percutaneous coronary intervention: sub-analysis of the SHINANO registry. AB - Although coronary artery disease (CAD) is common in patients with heart failure (HF), little is known about the prognostic significance of coronary lesion complexity in patients with prior HF undergoing percutaneous coronary intervention (PCI). The aim of this study was to investigate whether the coronary Synergy between Percutaneous Coronary Intervention with TAXus and Cardiac Surgery (SYNTAX) score could improve risk stratification in HF patients with CAD. Two hundred patients (mean age 73 +/- 11 years, left ventricular ejection fraction 49 +/- 15 %) with prior HF who underwent PCI were divided into two groups stratified by SYNTAX score (median value 12) and tracked prospectively for 1 year. The study endpoint was the composite of major adverse cardiovascular events (MACE), including all-cause death, myocardial infarction, stroke, and hospitalization for worsening HF. Adverse events were observed in 39 patients (19.5 %). Patients with high SYNTAX scores (n = 100) showed worse prognoses than those with low scores (n = 100) (26.0 vs. 13.0 %, respectively, P = 0.021). In multivariate Cox-regression analysis, SYNTAX score >=12 was significantly associated with MACE (hazard ratio: 1.99, 95 % confidence interval: 1.02-3.97; P = 0.045). In patients with prior HF and CAD, high SYNTAX scores predicted a high incidence of MACE. These results suggest that the SYNTAX score might be a useful parameter for improving risk stratification in these patients. PMID- 27709328 TI - Successful closure of defects in the upper gastrointestinal tract by endoscopic vacuum therapy (EVT): a prospective cohort study. AB - BACKGROUND: Perforations and anastomotic leakages of the upper gastrointestinal (GI) tract cause a high morbidity and mortality rate. Only limited data exist for endoscopic vacuum therapy (EVT) in the upper GI tract. METHODS: Fifty-two patients (37 men and 15 women, ages 41-94 years) were treated (12/2011-12/2015) with EVT for anastomotic insufficiency secondary to esophagectomy or gastrectomy (n = 39), iatrogenic esophageal perforation (n = 9) and Boerhaave syndrome (n = 4). After diagnosis, polyurethane sponges were endoscopically positioned with a total of 390 interventions and continuous negative pressure of 125 mm of mercury (mmHg) was applied to the EVT-system. Sponges were changed endoscopically twice per week. Clinical and therapy-related data and mortality were analyzed. RESULTS: After 1-25 changes of the sponge at intervals of 3-5 days with a mean of 6 sponge changes and a mean duration of therapy of 22 days, the defects were healed in 94.2 % of all patients without revision surgery. In three patients (6 %), EVT failed. Two of these patients died due to hemorrhage related to EVT. Four postinterventional strictures were observed during the follow-up of up to 4 years. CONCLUSION: Esophageal wall defects of different etiology in the upper gastrointestinal tract can be treated successfully with EVT, considering that indication for EVT should be weighed carefully. EVT can be regarded as a novel life-saving therapeutic tool. PMID- 27709329 TI - Assessment of treatment options for rectosigmoid cancer: single-incision plus one port laparoscopic surgery, single-incision laparoscopic surgery, and conventional laparoscopic surgery. AB - BACKGROUND: The advantages of reduced-port laparoscopic surgery (RPLS) for rectosigmoid cancer treatment have been disputed. This study evaluated the outcomes of RPLS compared to conventional laparoscopic surgery (CLS) for rectosigmoid cancer. METHODS: Data from 211 patients who underwent a selective sigmoidectomy or anterior resection from August 2011 to June 2014 at a single institution were collected and analyzed via propensity score matching. Operative outcomes, inflammatory responses, pain intensity, oncologic outcomes, quality of life, and cosmetic results were compared between groups. RESULTS: After matching, 96 patients (48 CLS and 48 RPLS) were evaluated. Sixteen RPLS cases underwent single-incision laparoscopic surgery (SILS), and 32 underwent single-incision plus one port laparoscopic surgery (SILS + 1). Baseline clinical characteristics were comparable between the RPLS and the CLS groups. Morbidity, pathologic outcomes, and 3-year disease-free survival and overall survival rates were also comparable between the 2 groups. Compared with the CLS group, the RPLS group had a shorter total incision length (p < 0.001); shorter time to liquid diet (p = 0.027), ambulation (p = 0.026), and discharge (p < 0.001); and lower visual analogue scale scores during mobilization at postoperative days 3-5 (p < 0.05). The total operation times, C-reactive protein levels at 24 h and 96 h, and interleukin-6 levels at 24 h postoperatively were significantly lower in the SILS + 1 group than those in the CLS and SILS groups (p < 0.05). Compared with the CLS group, the RPLS group showed better social functioning at 6 months postoperatively (p = 0.011). The SILS and SILS + 1 groups showed similar cosmetic results, and both groups showed better results than the CLS group (p < 0.001). CONCLUSIONS: RPLS for rectosigmoid cancer is feasible, with short-term safety and long-term oncological safety comparable to that of CLS. Better cosmesis and accelerated recovery can be expected. SILS + 1 is a better choice than CLS or SILS for rectosigmoid cancer because it minimizes invasiveness and reduces technical difficulties. PMID- 27709330 TI - Microvascular Function in Aging Among Women Living with HIV. AB - Combined antiretroviral therapy (CART) has turned HIV-infection to a treatable chronic disease during which many patients survive to middle and older age. However, they prematurely develop non-AIDS comorbidities such as cardiovascular disease, metabolic syndrome, diabetes, and HIV-associated neurocognitive disorders (HAND). Microcirculatory changes and endothelial dysfunction occur early both in HIV-infected and in aging patients, in whom they usually precede cardiovascular and neurocognitive impairments. Also, mild cognitive involvement has been reported in women during the menopausal transition. Disruption of the blood-brain barrier, as well as microvascular and cerebral blood flow changes, has been reported in HIV patients with HAND, including postmenopausal women. However, most studies addressing this issue included women aged less than 50 years. Whether HIV-infected women growing older with CART would be subsequently exposed to an increased progression of cognitive impairment overtime remains unknown. PMID- 27709331 TI - How to Diagnose and Treat Functional Chest Pain. AB - OPINION STATEMENT: Chest pain that is not explained by reflux disease or cardiac, musculoskeletal, mucosal, or motor esophageal abnormalities is classified as functional chest pain (FCP). Although several mechanisms are involved, esophageal hypersensitivity plays a major role and it could be considered a biomarker for FCP. Psychologic comorbidity such as anxiety, neuroticism, depression, and somatization is common. When the diagnosis of FCP is suspected, patients should undergo evaluation with esophageal motility testing, endoscopy, 24-h esophageal pH monitoring, and in some cases, sensory tests. Once the diagnosis of FCP has been established, treatment options rely on controlling patients' symptoms. Medical treatment has focused predominantly on medications that target pain, such as antidepressants and other pain neuromodulators. Non-pharmacologic interventions with complementary behavioral treatments, such as cognitive behavioral therapy, biofeedback, and hypnosis, have recently been recognized as useful in FCP patients. The latest findings on the evaluation and treatment of FCP are outlined herein. PMID- 27709334 TI - Editorial.

AB - OPINION STATEMENT: As new and effective novel therapies in inflammatory bowel disease (IBD) become available, patients are living longer with advancing age and are at increased risk for malignancy. The management of IBD and malignancy involves multiple combinations of chemotherapy agents and IBD drugs, with the potential for interactions between these therapies. Interactions may either potentiate the effectiveness of drug class or exacerbate their common side effects. In this review article, we present a guide on studied interactions between IBD therapies and chemotherapy agents, specifically those of colorectal cancer, breast cancer, non-Hodgkin's lymphoma, and melanoma. The pharmacology and pharmocokinetics of each IBD drug will be discussed. Then, the IBD drug and chemotherapy interactions are summarized in table format. This guide will provide a quick reference to guide clinicians with this challenging management of two disease processes. PMID- 27709336 TI - ? PMID- 27709341 TI - Editorial. PMID- 27709342 TI - The role of elastases in the development of emphysema. AB - Enzymes which degrade elastin can disorganize the network of elastic fibers in the lungs of experimental animals and produce emphysema. Two sources of endogenous elastases in the lung are neutrophils and alveolar macrophages. The neutrophil elastase is an intracellular, granule-associated enzyme which is inhibited by alpha1-antitrypsin and has the capacity to produce emphysema in experimental animals. The recently identified macrophage elastase appears to be a secretory enzyme, not associated with granules and less effectively inhibited by alpha1-antitrypsin. The demonstration that macrophages from cigarette smokers release elastase in culture, and that cigarette smoke interferes with the action of inhibitors of elastase, suggests that elastases may be involved in the pathogenesis of emphysema in man. Further research is needed to establish whether degradation of elastin occurs in humans developing emphysema. PMID- 27709349 TI - Bathing in carbon dioxide-enriched water alters protein expression in keratinocytes of skin tissue in rats. AB - Beneficial effects of balneotherapy using naturally occurring carbonated water (CO2 enriched) have been known since the Middle Ages. Although this therapy is clinically applied for peripheral artery disease and skin disorder, the underlying mechanisms are not fully elucidated.Under controlled conditions, rats were bathed in either CO2-enriched water (CO2 content 1200 mg/L) or tap water, both at 37 degrees C, for 10 min daily over 4 weeks. Proliferation activity was assessed by Ki67 immunohistochemistry of the epidermis of the abdomen. The capillary density was assessed by immunodetection of isolectin-positive cells. Using cryo-fixed abdominal skin epidermis, follicle cells and stroma tissue containing capillaries were separately isolated by means of laser microdissection and subjected to proteomic analysis using label-free technique. Differentially expressed proteins were validated by immunohistochemistry.Proliferation activity of keratinocytes was not significantly different in the epidermis after bathing in CO2-enriched water, and also, capillary density did not change. Proteomic analysis revealed up to 36 significantly regulated proteins in the analyzed tissue. Based on the best expression profiles, ten proteins were selected for immunohistochemical validation. Only one protein, far upstream element binding protein 2 (FUBP2), was similarly downregulated in the epidermis after bathing in CO2-enriched water with both techniques. Low FUBP2 expression was associated with low c-Myc immune-expression in keratinocytes.Long-term bathing in CO2-enriched water showed a cellular protein response of epithelial cells in the epidermis which was detectable by two different methods. However, differences in proliferation activity or capillary density were not detected in the normal skin. PMID- 27709350 TI - Effect of Side-Specific Valvular Shear Stress on the Content of Extracellular Matrix in Aortic Valves. AB - Responses of valve endothelial cells (VECs) to shear stresses are important for the regulation of valve durability. However, the effect of flow patterns subjected to VECs on the opposite surfaces of the valves on the production of extracellular matrix (ECM) has not yet been investigated. This study aims to investigate the response of side-specific flow patterns, in terms of ECM synthesis and/or degradation in porcine aortic valves. Aortic and ventricular sides of aortic valve leaflets were exposed to oscillatory and laminar flow generated by a Cone-and-Plate machine for 48 h. The amount of collagen, GAGs and elastin was quantified and compared to samples collected from the same leaflets without exposing to flow. The results demonstrated that flow is important to maintain the amount of GAGs and elastin in the valve, as compared to the effect of static conditions. Particularly, the laminar waveform plays a crucial role on the modulation of elastin in side-independent manner. Furthermore, the ability of oscillatory flow on the aortic surface to increase the amount of collagen and GAGs cannot be replicated by exposure of an identical flow pattern on the ventricular side of the valve. Side-specific responses to the particular patterns of flow are important to the regulation of ECM components. Such understanding is imperative to the creation of tissue-engineered heart valves that must be created from the "appropriate" cells that can replicate the functions of the native VECs to regulate the different constituents of ECM. PMID- 27709351 TI - Adverse effects of non-hormonal pharmacological interventions in breast cancer survivors, suffering from hot flashes: A systematic review and meta-analysis. AB - PURPOSE: To access frequency and severity of adverse effects (AE) of non-hormonal drugs (NHD) for hot flashes in breast cancer survivors compared to controls and analyze adverse-effect risk by reviewing published randomized trials. METHODS: Cochrane Central Register for Controlled Trials, Embase, Medline, PsycINFO and PubMed databases were searched. Trials were included where participants were survivors of breast cancer suffering from hot flashes, treatment included self administered venlafaxine, gabapentin or clonidine, and AE were reported. AE frequency and severity were graded. A meta-analysis of ten trials with sub-group analyses was conducted. RESULTS: Forty-nine studies were identified, and 12 were included. A total of 1467 participants experienced 772 adverse effects, 81 % (n = 627) in the treatment group and 19 % (n = 145) in the control group. Sixty-seven percent of AE was graded as mild and 33 % as moderate. The frequency of AE for NHD was overall significant compared to placebo. Sub-group analysis indicated that AE frequency and severity increased at higher doses of venlafaxine and gabapentin compared to placebo. CONCLUSION: The odds for experiencing AE was significantly higher in patients randomized to high-dose NHD than those randomized to controls, including placebo, low-dose medication and acupuncture. These therapies should be considered as a potential treatment alternative. PMID- 27709352 TI - A prospective study to assess the clinical utility of serum HER2 extracellular domain in breast cancer with HER2 overexpression. AB - PURPOSE: We explored the clinical utility of human epidermal growth factor receptor-2 extracellular domain (HER2/ECD) in patients treated for an invasive breast cancer with HER2 overexpression. METHODS: We prospectively studied HER2/ECD levels in the sera of 334 women included between 2007 and 2014, all treated with trastuzumab. HER2/ECD levels were measured at diagnosis, during treatments, and along the follow-up. We investigated the relationship of HER2/ECD with other clinicopathological parameters at diagnosis, its prognosis value, and its utility during the monitoring of a neoadjuvant treatment and the follow-up. RESULTS: Elevated HER2/ECD at diagnosis correlated positively with parameters associated with tumor aggressiveness. Disease-free survival of non-metastatic patients was significantly shorter in patients with high HER2/ECD at diagnosis (HR = 13.6, 95 % CI 1.6-113.6, P < 0.0001). Progression-free survival of metastatic patients was better for patients with low HER2/ECD (HR = 2.6, 95 % CI 1.2-5.3, P = 0.033). A multivariate analysis revealed that HER2/ECD level at diagnosis was an independent prognosis factor. During neoadjuvant therapy, a significant decrease in HER2/ECD was reported only for the complete histological response group (P = 0.031). During the follow-up, HER2/ECD helped predict relapse, disease progression, and metastases before imaging in 18.6 % cases of the studied cohort. CONCLUSIONS: HER2/ECD is a prognosis factor that is valuable in evaluating the neoadjuvant treatment efficiency. HER2/ECD also appears to be a helpful surveillance biomarker for the early diagnosis of relapses and to predict the fate of metastases. This study brings evidences to support the use of HER2/ECD in the management of HER2-positive breast cancer. PMID- 27709355 TI - Rapidly dissolving polymeric microneedles for minimally invasive intraocular drug delivery. AB - In this study, dissolving microneedles (MNs) were used to enhance ocular drug delivery of macromolecules. MNs were fabricated using polyvinylpyrrolidone (PVP) polymer of various molecular weights (MWs) containing three model molecules of increasing MW, namely fluorescein sodium and fluorescein isothiocyanate-dextrans (with MW of 70 k and 150 k Da). Arrays (3 * 3) of PVP MNs with conical shape measuring about 800 MUm in height with a 300 MUm base diameter, containing the model drugs, were fabricated and characterized for their fracture forces, insertion forces (in the sclera and cornea), depth of penetration (using OCT and confocal imaging), dissolution time and in vitro permeation. The average drug content of the MNs (only in MN shafts) ranged from 0.96 to 9.91 MUg, and the average moisture content was below 11 %. High MW PVP produced MNs that can withstand higher forces with minimal reduction in needle height. PVP MNs showed rapid dissolution that ranged from 10 to 180 s, which was dependent upon PVP's MW. In vitro studies showed significant enhancement of macromolecule permeation when MNs were used, across both the corneal and scleral tissues, in comparison to topically applied aqueous solutions. Confocal images showed that the macromolecules formed depots within the tissues, which led to sustained permeation. However, use of MNs did not significantly benefit the permeation of small molecules; nevertheless, MN application has the potential for drug retention within the selected ocular tissues unlike topical application for small molecules. The material used in the fabrication of the MNs was found to be biocompatible with retinal cells (i.e. ARPE-19). Overall, this study reported the design and fabrication of minimally invasive rapidly dissolving polymeric MN arrays which were able to deliver high MW molecules to the eye via the intrastromal or intrascleral route. Thus, dissolving MNs have potential applications in enhancing ocular delivery of both small and macromolecules. PMID- 27709356 TI - Prevalence of avian haemosporidian parasites is positively related to the abundance of host species at multiple sites within a region. AB - Parasite prevalence is thought to be positively related to host population density owing to enhanced contagion. However, the relationship between prevalence and local abundance of multiple host species is underexplored. We surveyed birds and their haemosporidian parasites (genera Plasmodium and Haemoproteus) at multiple sites across eastern North America to test whether the prevalence of these parasites in a host species at a particular site is related to that host's local abundance. Prevalence was positively related to host abundance within most sites, although the effect was stronger and more consistent for Plasmodium than for Haemoproteus. In contrast, prevalence was not related to variation in the abundance of most individual host species among sites across the region. These results suggest that parasite prevalence partly reflects the relative abundances of host species in local assemblages. However, three nonnative host species had low prevalence despite being relatively abundant at one site, as predicted by the enemy release hypothesis. PMID- 27709360 TI - Mediterranean meal versus Western meal effects on postprandial ox-LDL, oxidative and inflammatory gene expression in healthy subjects: a randomized controlled trial for nutrigenomic approach in cardiometabolic risk. AB - AIMS: Inflammation and oxidative damage contribute significantly to the development of cardiovascular diseases (CVD). Postprandial oxidative stress and inflammation are characterized by an increased susceptibility of the organism toward oxidative damage after consumption of a meal rich in lipids and/or carbohydrates. Micronutrients modulate immune system and exert a protective action by reducing oxidized low-density lipoprotein (ox-LDL) level. The aim of the present study was to evaluate the postprandial plasma ox-LDL level and the gene expression of 13 genes related to oxidative stress (HOSp) and human inflammasome pathways (HIp), after a tocopherol-enriched Mediterranean meal (TEM), and a Western high-fat meal (HFM). Moreover, Mediterranean Adequacy Index was calculated to define the quality of both meals. METHODS: We set up a randomized and crossover trial in healthy human volunteers. Ox-LDL level was measured by enzyme-linked immunosorbent assay and the gene expression of 13 genes related to HOSp and HIp by qRT-PCR. RESULTS: Ox-LDL levels significantly decreased comparing HFM versus TEM (p < 0.05). Percentages of significantly overexpressed genes after each dietary treatment are as follows: (A) baseline versus HFM: 7.69 % HIp and 23.08 % HOSp; (B) baseline versus TEM: 7.69 % HIp and 7.69 % HOSp; (C) HFM versus TEM: 15.38 % HIp and 15.38 % HOSp. CONCLUSIONS: TEM reduced postprandial risk factors of CVD, such as ox-LDL, and the expression of inflammation and oxidative stress-related genes. Chronic studies on larger population are necessary before definitive conclusions. TRIAL REGISTRATION: ClinicalTrials.gov Id: NCT01890070. PMID- 27709361 TI - Macroscopic features predict outcome in patients with pancreatic ductal adenocarcinoma. AB - As macroscopic appearance represents tumor microenvironment, it may also reflect the biological and clinicopathological characteristics of a cancer. The aim of the study was to evaluate the clinicopathological significance of the gross appearance of pancreatic ductal adenocarcinoma (PDA). We investigated fresh macroscopic features in 352 cases of PDA and their clinicopathological significance. Three unique gross features were found: a honeycomb-like appearance (diffusely distributed microcysts and interstitial fibrotic thickening), macroscopic necrosis, and a tube/branching structure (apparent small cylindrical or linear structure). A honeycomb-like appearance was present in 24 cases (6.8 %) and significantly associated with low serum CA19-9 level and well-differentiated adenocarcinoma. Macroscopic necrosis was present in 235 cases (66.8 %) and significantly correlated with tumor size, nodal metastasis, nerve plexus invasion, no adjuvant chemotherapy, and distant recurrence. The presence of macroscopic necrosis was significantly associated with shorter disease-specific survival (DSS) and disease-free survival (DFS). The presence of larger areas of necrosis (>=2 mm) was closely associated with shorter survival. A tube/branching structure was found in 179 cases (50.9 %), which was correlated with larger tumor size and no adjuvant chemotherapy and macroscopic necrosis. The presence of a tube/branching structure was significantly associated with shorter DSS and DFS. Multivariate survival analyses showed that the presence of tube/branching structures was an independent negative prognostic factor in patients having PDA. We suggest that the gross appearance of PDA reflects clinicopathological characteristics and may be useful in predicting prognosis. PMID- 27709362 TI - Physeal histological morphology after thermal epiphysiodesis using radiofrequency ablation. AB - BACKGROUND: Several treatments have been described for leg length discrepancy. Epiphysiodesis is the most commonly used because of its effectiveness. Thermal epiphysiodesis using radiofrequency ablation (RFA) alters the growth plate morphology without damaging the adjacent articular cartilage; it is a minimally invasive method that has shown excellent results in animal models. This study describes the macro and micro morphology after the procedure. MATERIALS AND METHODS: Epiphysiodesis using RFA was performed in vivo for 8 min (92-98 degrees C) at two ablation sites (medial and lateral) in one randomly-selected tibia in eight growing pigs. The contralateral tibia was used as control. After 12 weeks, the pigs were killed and the tibiae harvested. The specimens were studied macroscopically and histology samples were obtained. Physeal morphology, thickness and characteristics were then described. RESULTS: Macroscopically, the articular cartilage was normal in all the treated tibiae. Microscopically, the physis was detected as a discontinuous line on the treated tibiae while it was continuous in all controls. In the control specimens, the mean thickness of the physis was 625 um (606-639, SD = 14). All the physeal layers were organized. In the ablated specimens, disorganized layers in a heterogeneous line were observed. Bone bridges were identified at the ablation sites. The central part of the physis looked normal. Next to the bone bridge, the physis was thicker and presented fibrosis. The mean thickness was 820 um (628-949, SD = 130). No abnormalities in the articular cartilage were observed. CONCLUSIONS: Thermal epiphysiodesis with RFA disrupts the physeal morphology and causes the formation of bone bridges at the ablation sites. This procedure does not damage the adjacent articular cartilage. The damaged tissue, next to the bone bridges, is characterized by disorganization and fibrosis. PMID- 27709363 TI - Sexually Explicit Media Use by Sexual Identity: A Comparative Analysis of Gay, Bisexual, and Heterosexual Men in the United States. AB - Advances in production and distribution of sexually explicit media (SEM) online have resulted in widespread use among men. Limited research has compared contexts of use and behaviors viewed in Internet SEM by sexual identity. The current study examined differences in recent SEM use (past 6 months) by sexual identity among an ethnically diverse sample of 821 men who completed an online survey in 2015. Both gay and bisexual men reported significantly more frequent use of Internet SEM compared to heterosexual men. Although most participants reported viewing SEM at home (on a computer, tablet, or smartphone), significantly more gay men reported SEM use at a sex party or commercial sex venue than either heterosexual or bisexual men. Sexual identity predicted viewing of high-risk and protective behaviors in separate logistic regression models. Specifically, compared to heterosexual men, gay and bisexual men had increased odds of viewing condomless anal sex (gay OR 5.20, 95 % CI 3.35-8.09; bisexual OR 3.99, 95 % CI 2.24-7.10) and anal sex with a condom (gay OR 3.93, 95 % CI 2.64-5.83; bisexual OR 4.59, 95 % CI 2.78-7.57). Compared to gay men, heterosexual and bisexual men had increased odds of viewing condomless vaginal sex (heterosexual OR 27.08, 95 % CI 15.25 48.07; bisexual OR 5.59, 95 % CI 3.81-8.21) and vaginal sex with a condom (heterosexual OR 7.90, 95 % CI 5.19-12.03; bisexual OR 4.97, 95 % CI 3.32-7.44). There was also evidence of identity discrepant SEM viewing as 20.7 % of heterosexual-identified men reported viewing male same-sex behavior and 55.0 % of gay-identified men reported viewing heterosexual behavior. Findings suggest the importance of assessing SEM use across media types and contexts and have implications for research to address the potential influence of SEM on sexual behavior (e.g., investigate associations between viewing condomless vaginal sex and engaging in high-risk encounters with female partners).

AB - The Cao Vit gibbon (Nomascus nasutus) has only one population with about 110 individuals living in a degraded karst forest along the China-Vietnam border. Investigation of food choice in relation to chemical nutrition will offer important insights into its conservation. We studied the food choice of two groups of Cao Vit gibbons using instantaneous scan sampling in Bangliang National Nature Reserve, Guangxi, China, over 4 years, and analyzed the chemical components (total nitrogen, TN; water-soluble sugar, WSS; crude fat, CF; neutral detergent fiber, NDF; acid detergent fiber, ADF; acid detergent lignin, ADL; condensed tannin, CT; and ash) of 48 food plant parts and 22 non-food plant parts. Fruits and figs that are rich in sugar are important food resources for gibbons. For other food types, flowers are a good source of total nitrogen and carbohydrates, and leaves and buds provide sources of protein and minerals. Cao Vit gibbons selected fruits that contain less total nitrogen, less acid detergent fiber and more water-soluble sugar than non-food fruits. Several food species that were heavily consumed by Cao Vit gibbons are suggested as potential tree species for ongoing habitat restoration. PMID- 27709364 TI - beta-Adrenergic modulation of cancer cell proliferation: available evidence and clinical perspectives. AB - PURPOSE: In this review, we aimed to present and discuss the available preclinical and epidemiological evidences regarding the modulation of cancer cell proliferation by beta-adrenoceptors (beta-AR), with a specific focus on the putative effects of beta-blockers according to their pharmacological properties. METHODS: A comprehensive review of the published literature was conducted, and the evidences concerning the involvement of beta-AR in cancer as well as the possible role of beta-blockers were selected and discussed. RESULTS: The majority of reviewed studies show that: (1) All the cancer types express both beta1- and beta2-AR, with the exception of neuroblastoma only seeming to express beta2-AR; (2) adrenergic agonists are able to increase proliferation of several types of cancers; (3) the proliferative effect seems to be mediated by both beta1- and beta2-AR; (4) binding to beta-AR results in a cAMP transient flux which activates two major downstream effector systems: protein kinase A and EPAC and (5) beta blockers might be putative adjuvants for cancer treatment. CONCLUSIONS: Overall, the reviewed studies show strong evidences that beta-AR activation, through several intracellular mechanisms, modulate tumor cell proliferation suggesting beta-blockers can be a feasible therapeutic approach to antagonize beta adrenergic response or have a protective effect per se. This review highlight the need for intensifying the research not only on the molecular mechanisms underlying the beta-adrenergic influence in cancer, but also on the implications of biased agonism of beta-blockers as potential antitumor agents.

AB - A citation analysis of more than 2500 works on the childbearing and menstrual psychoses has shown that the average number of citations is 1 % of the literature or less; Anglo-Saxon authors have the lowest standards of scholarship. Many excellent works have received few of no citations. Attention is drawn to citation fraud and the pernicious effect of superficial "reviews." PMID- 27709367 TI - A test of the reward-value hypothesis. AB - Rats retain source memory (memory for the origin of information) over a retention interval of at least 1 week, whereas their spatial working memory (radial maze locations) decays within approximately 1 day. We have argued that different forgetting functions dissociate memory systems. However, the two tasks, in our previous work, used different reward values. The source memory task used multiple pellets of a preferred food flavor (chocolate), whereas the spatial working memory task provided access to a single pellet of standard chow-flavored food at each location. Thus, according to the reward-value hypothesis, enhanced performance in the source memory task stems from enhanced encoding/memory of a preferred reward. We tested the reward-value hypothesis by using a standard 8-arm radial maze task to compare spatial working memory accuracy of rats rewarded with either multiple chocolate or chow pellets at each location using a between subjects design. The reward-value hypothesis predicts superior accuracy for high valued rewards. We documented equivalent spatial memory accuracy for high- and low-value rewards. Importantly, a 24-h retention interval produced equivalent spatial working memory accuracy for both flavors. These data are inconsistent with the reward-value hypothesis and suggest that reward value does not explain our earlier findings that source memory survives unusually long retention intervals. PMID- 27709370 TI - Biomechanical evaluation of cornea in patients with ankylosing spondylitis. AB - PURPOSE: The aim of this study was to evaluate the corneal biomechanical parameters in patients with ankylosing spondylitis (AS) and to compare them with the healthy subjects. METHODS: Sixty patients with AS (study group) and 60 healthy subjects (control group) were enrolled in this prospective study. The study group was further classified as active (n:30) and inactive (n:30). After detailed ophthalmological examination including intraocular pressure (IOP) measurement with Goldmann applanation tonometer (IOPGAT), corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated IOP (IOPcc), and Goldmann-correlated IOP (IOPg) were measured with the Reichert Ocular Response Analyzer (ORA). Central corneal thickness (CCT) was measured with the Spectral Domain Optical Coherence Tomography (SD-OCT). RESULTS: The study group's mean CH, CCT, IOPg, and IOPGAT values were lower than the control group (p < 0.05 for all variables). The mean CH, CRF, CCT, IOPg, and IOPGAT values were higher in active patients when compared to the inactive ones (p < 0.001, p < 0.001, p = 0.013, p = 0.021, and p = 0.002, respectively). CONCLUSIONS: AS patients have lower CCT, CH, IOPg, and IOPGAT when compared with healthy subjects. In the active stage of AS, patients present with higher levels of corneal biomechanical parameters with thicker corneas. IOPcc is a more accurate measurement than IOPGAT or IOPg in AS patients. PMID- 27709371 TI - Visual outcomes after lensectomy and iris claw artisan intraocular lens implantation in patients with Marfan syndrome. AB - PURPOSE: To review our experience with crystalline lens extraction and iris claw Artisan IOL implantation in patients with lens subluxation secondary to Marfan syndrome. METHODS: A retrospective analysis of 12 eyes of 9 patients with lens subluxation due to Marfan syndrome who underwent crystalline lens removal and Artisan IOL (Ophtec, Groningen, Netherlands) implantation. A questionnaire of pre and post-operative data, including demographics, pre- and postoperative comorbidities and complications was completed. Patients were evaluated for visual outcome and occurrence of complications. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), and spherical equivalents (SE) were compared before and after lens extraction and IOL insertion. RESULTS: The mean age of the participants was 30.03 +/- 15.02 years, and mean post-operative follow-up time was 44.5 +/- 16.4 months. Mean BCVA also showed a significant improvement from 0.5 +/- 0.3 at the baseline to 0.2 +/- 0.2 post-operatively (P = 0.006). SE changed significantly from -11.38 +/- 1.99 preoperatively to -0.45 +/- 1.65 post operatively (P = 0.003). All eyes had the IOL implanted at desired position. Post operative complications were retinal detachment in one case and IOL dislocation in another patient. No other complication such as ocular hypertension, angle abnormalities, clinical cystoids macular edema, and corneal decompensation was observed during the follow-up period. CONCLUSION: Artisan IOL implantation after lens extraction appears to be an attractive alternative for optical correction in cases of Marfan syndrome with ectopia lentis. It confers a significant improvement in visual acuity with reasonable risk profile. PMID- 27709372 TI - Genomic analyses identify agents regulating somatotroph and lactotroph functions. AB - Isolated hormone deficiency might be caused by loss of a specific type of endocrine cells, and regenerating these missing cells may provide a new option for future treatment. It is known that POU1F1 lineage cells can differentiate into thyrotroph, somatotroph, and lactotroph. However, there is no effective way of controlling pituitary stem/progenitor cells to differentiate into a specific type of endocrine cell. We thereby analyzed multiple genomic publications related to POU1F1 and pituitary development in this study to identify genes and agents regulating POU1F1 lineage cell differentiation. ANOVA analyses were performed to obtain differentially expressed genes. Ingenuity pathway analyses were performed to obtain signaling pathways, interaction networks, and upstream regulators. Venn diagram was used to determine the overlapping information between studies. Summary statistics was performed to rank genes according to their frequency of occurrence in these studies. The results from upstream analyses indicated that 326 agents may regulate pituitary cell differentiation. These agents can be categorized into 12 groups, including hormones and related pathways, PKA-cAMP pathways, p53/DNA damaging/cell cycle pathways, immune/inflammation regulators, growth factor and downstream pathways, retinoic/RAR pathways, ROS pathways, histone modifications, CCAAT/enhancer binding protein family, neuron development/degeneration pathways, calcium related and fat acid, and glucose pathways. Additional experiments demonstrated that H2O2 and catalase differentially regulate growth hormone and prolactin expression in somatolactotroph cells, confirming potential roles of ROS pathway on regulating somatotroph and lactotroph functions.

AB - This is a pioneer study of single nucleotide polymorphisms (SNPs) within the entire promoter region (1204 bp) of the dominant pPAG2-L subfamily in the pig. The pPAG2-L subfamily was sequenced/examined using genomic deoxyribonucleic acid (gDNA) templates of crossbreed pigs (Landrace x Large White), and compared to two bacterial artificial chromosome (BAC) clones containing gDNA of the Duroc breed (as the positive controls). Our analysis of the pPAG2-L promoter identified 31 SNPs and one InDel mutation in crossbreed pigs. Among 42 SNPs identified in two BAC clones, 24 SNPs had not been previously detected in crossbreed pigs. The sequence alignment of pPAG2-L promoter, performed with Lasagne-Search 2.0, Cluster Bluster and MatInspector software, revealed a total of 28 transcription factor binding sites (TFBS) and 10 TFBS (AP-1, CCAAT, CHOP:C, FOXP1, LSF, MRF-2, Myc, NF1, NF-Y, TGIF) within SNPs in the core sequences. It was noted that TFBS (NF1) was found to be unique to the pPAG2 promoter sequence containing SNPs: g. 1100G>A(R), g.-1101T>C(Y), represented by GA and TC genotypes (p x = 0.12). Our broad-based novel database thus provides an SNP PAG2-L pattern for modern genotyping of female and male progenitors. This is required for further studies of various potential correlations between guiding SNP genotypes of the pPAG2-L subfamily in the sows of many breeds, in which the most economically important reproductive traits are properly documented on each farm.

AB - In this study, carbohydrate-chitosan composite including glucose-chitosan, sucrose-chitosan and starch-chitosan with varied carbohydrate concentrations were prepared as carriers for Vero cell culture. Our results show that among these composites, 30 % starch-chitosan composite (STC) were the best carriers for the growth of Vero cells. The initial number of attached cells on the surface of composite carriers did not have any significant effect on subsequent cell production. A higher glucose level in the growth medium during the exponential phase of cell growth, however, played an important factor for cell production. Vero cells on the STC carriers were able to convert starch inside the composite carriers into glucose and further utilized the glucose for their growth. Moreover, by crosslink with serum the STC carriers supported an even better cell production in the normal medium without adding fetal bovine serum, as well as a good extracellular virus production. The STC composite is therefore a promising alternative carrier for Vero cell culture. PMID- 27709376 TI - Explication and Definition of Mental Health Recovery: A Systematic Review. AB - This review assessed the concordance of the literature on recovery with the definition and components of recovery developed by the Substance Abuse and Mental Health Services Administration (SAMHSA). Each SAMHSA identified recovery component was first explicated with synonyms and keywords and made mutually exclusive by authors. Inter-rater reliability was established on the coding of the presence of 17 recovery components and dimensions in 67 literature reviews on the recovery concept in mental health. The review indicated that concordance varied across SAMHSA components. The components of recovery with greatest concordance were: individualized/person centered, empowerment, purpose, and hope.

PMID- 27709374 TI - Exploring drought stress-regulated genes in senna (Cassia angustifolia Vahl.): a transcriptomic approach. AB - De novo assembly of reads produced by next-generation sequencing (NGS) technologies offers a rapid approach to obtain expressed gene sequences for non model organisms. Senna (Cassia angustifolia Vahl.) is a drought-tolerant annual undershrub of Caesalpiniaceae, a subfamily of Fabaceae. There are insufficient transcriptomic and genomic data in public databases for understanding the molecular mechanism underlying the drought tolerance of senna. Therefore, the main purpose of this study was to know the transcriptome profile of senna, with special reference to drought stress. RNA from two different stages of leaf development was extracted and sequenced separately using the Illumina technology. A total of 200 million reads were generated, and a de novo assembly of processed reads in the pooled transcriptome using Trinity yielded 43,413 transcripts which were further annotated using NCBI BLAST with "green plant database (txid 33090)," Swiss Prot, Kyoto Encyclopedia of Genes and Genomes (KEGG), Clusters of Orthologous Groups (COG), and Gene Ontology (GO). Out of the total transcripts, 42,280 (95.0 %) were annotated by BLASTX against the green plant database of NCBI. Senna transcriptome showed the highest similarity to Glycine max (41 %), followed by Phaseolus vulgaris (16 %), Cicer arietinum (15 %), and Medicago trancatula (5 %). The highest number of GO terms were enriched for the molecular functions category; of these "catalytic activity" (GO: 0003824) (25.10 %) and "binding activity" (GO: 0005488) (20.10 %) were most abundantly represented. We used InterProscan to see protein similarity at domain level; a total of 33,256 transcripts were annotated against the Pfam domains. The transcripts were assigned with various KEGG pathways. Coding DNA sequences (CDS) encoding various drought stress-regulated pathways such as signaling factors, protein modifying/degrading enzymes, biosynthesis of phytohormone, phytohormone signaling, osmotically active compounds, free radical scavengers, chlorophyll metabolism, leaf cuticular wax, polyamines, and protective proteins were identified through BLASTX search. The lucine-rich repeat kinase family was the most abundantly found group of protein kinases. Orphan, bHLH, and bZIP family TFs were the most abundantly found in senna. Six genes encoding MYC2 transcription factor, 9-cis-epoxycarotenoid dioxygenase (NCED), l -ascorbate peroxidase (APX), aminocyclopropane carboxylate oxidase (ACO), abscisic acid 8'-hydroxylase (ABA), and WRKY transcription factor were confirmed through reverse transcriptase-PCR (RT-PCR) and Sanger sequencing for the first time in senna. The potential drought stress-related transcripts identified in this study provide a good start for further investigation into the drought adaptation in senna. Additionally, our transcriptome sequences are the valuable resource for accelerated genomics assisted genetic improvement programs and facilitate manipulation of biochemical pathways for developing drought-tolerant genotypes of crop plants. PMID- 27709378 TI - Substrate Specificity of Na+,Cl-(HCO3-)-ATPase. AB - We studied substrate specificity of Na+,Cl-(HCO3-)-ATPase. In most cases, replacement of ATP for other phosphate-containing substances resulted in not only pronounced suppression of phosphohydrolase reactions, but also dramatic changes of their responsiveness to the stimulating effect of monovalent ions. The data showed that Na+,Cl-(HCO3-)-ATPase is a highly specific enzyme for ATP. PMID- 27709379 TI - Compensatory Changes in the Brain Dopaminergic System of WAG/Rij Rats Genetically Predisposed to Absence Epilepsy. AB - Involvement of the brain dopaminergic system in the age-related dynamics of absence epilepsy in WAG/Rij rats was examined by histological, immunohistochemical, and electrophysiological (EEG) methods. We revealed reduced expression of dopamine receptors in various brain structures prior to first manifestations of the disease (at the age of 1-3 months), reduced density of neurons in the center of nigrostriatal system (substantia nigra pars compacta) in 10-month-old rats in comparison with 1-month-old rats, and positive correlation between neural density in the substantia nigra and intensity of epileptic activity in EEG. It is hypothesized that loss of dopaminergic neurons and reduced nigrostriatal dopaminergic innervation of the brain could prevent the development of absence epilepsy in WAG/Rij rats. PMID- 27709380 TI - Effect of Metabolic Stress on Coenzyme Q10 Content in Tissues of Active and Passive Rats. AB - The dynamics of coenzyme Q10 concentration in the blood plasma, liver, and brain of passive and active rats was studied on the model of metabolic stress. This parameter was shown to differ in rats with various patterns of behavior. Dietary consumption of coenzyme Q10 in doses of 10 and 100 mg/kg body weight was followed by changes in its content in experimental animals. PMID- 27709381 TI - Combined Effect of Low-Intensity Helium-Neon Laser and X-Ray Radiation on in Vivo Cellular Response of the Whole Blood and Lymphoid Organs in Mice. AB - We studied the effect of exposure to helium-neon laser (dose range 0.16-50 mJ/cm2) on activation of natural protection reserve in mice using the adaptive response test. DNA comets method revealed a protective response manifested in DNA damage level in whole blood leukocytes of mice and in lymphoid organs by the thymus and spleen weight index; preexposure to laser did not induce the adaptive response. ROS level in the whole blood was assessed by the level of zymosan induced luminol chemiluminescence. In mice subjected to adaptive laser irradiation in doses of 0.16-5 mJ/cm2 followed by X-ray irradiation in a dose of 1.5 Gy, the activation index calculated as the ratio of induced to spontaneous area of luminescence was by 1.4 times lower than that in non-irradiated animals, which attested to reduced ROSgeneration reserve capacity of neutrophils. PMID- 27709382 TI - Effect of Doxazosin on Autonomic Nervous Control and Urodynamics of Rat Urinary Bladder during Modeled Infravesical Obstruction. AB - The therapeutic effect of doxazosin (40 MUg/kg/day over one month) on urinary bladder was examined in female rats with modeled chronic infravesical obstruction (IVO) produced by graduated mechanical constriction of the proximal urethral segment. In one month, IVO induced a pronounced vesical hypertrophy both in treated and untreated rats that manifested in increased bladder weight and capacity, the latter increment being pronouncedly greater in treated rats. In untreated IVO rats, infusion cystometry revealed elevated basal intravesical pressure of void bladder P0, markedly increased maximal (premicturitional) pressure Pmax, and increased amplitude of spontaneous oscillations of intravesical pressure DeltaPdet in filled bladder. Doxazosin produced no significant effect on Pmax rise during IVO, but prevented elevation of P0 and increment of DeltaPdet in filled bladder. During gradual filling of urinary bladder in control (intact) rats, the parasympathetic vesical influences increased progressively, while in untreated IVO rats, the adrenergic influences prevailed even at maximal filling of the bladder. In IVO rats, doxazosin prevented the bias of the sympathetic-parasympathetic balance in the filled bladder in favor of sympathetic influences, but did not prevent this bias in a void bladder. It is hypothesized that alpha-adrenoblockers improve micturition during IVO caused by benign prostatic hyperplasia not only by decreasing the urethral resistance to urine flow due to down-regulation of prostate smooth muscle tone, but also by a direct action of these blockers on detrusor adrenergic receptors and central structures involved in urinary bladder control. PMID- 27709383 TI - Effect of Granulocyte Colony-Stimulating Factor Immobilized by the Electron-Beam Synthesis Nanotechnology on Reparative Regeneration of Spermatogenous Tissue. AB - Effectiveness of the granulocyte colony-stimulating factor immobilized by using electronbeam synthesis nanotechnology was investigated on the model of experimental testicular failure caused by the toxic effect on stem spermatogonia. Administration of the drug to experimental paclitaxel-treated animals increased the number of sources of the proliferative pool of spermatogenesis and its productivity. The effectiveness of immobilized granulocyte colony-stimulating factor was based on its ability to stimulate reparative regeneration of the spermatogenic tissue, which manifested in a decrease in spermatogenic layer maturity and increase in the number of microenvironment cells. Effectiveness of the immobilized form of the drug was superior to that of non-immobilized form. PMID- 27709384 TI - Effects of Humic Acids Isolated from Peat of Various Origin on in Vitro Production of Nitric Oxide: a Screening Study. AB - A screening study of biological activity of native humic acids isolated from peat was performed; several physical and chemical parameters of their structures were studied by UV- and infrared spectroscopy. Spectroscopy yielded similar shape of light absorption curves of humic acids of different origin, which can reflect similarity of general structural principles of these substances. Alkaline humic acids have more developed system of polyconjugation, while molecular structures of pyrophosphate humic acids were characterized by higher aromaticity and condensation indexes. Biological activity of the studied humic acids was assessed by NO-stimulating capacity during their culturing with murine peritoneal macrophages in a wide concentration range. It was shown that due to dose dependent enhancement of NO production humic acids can change the functional state of macrophages towards development of pro-inflammatory properties. These changes were associated with high activity of humic acids isolated by pyrophosphate extraction, which allows considering effects of isolation method on biological activity. PMID- 27709385 TI - Spatial Memory in the Progeny of Rats Subjected to Different Types of Experimental Preeclampsia. AB - Spatial memory was studied in 2-month-old offspring of rats subjected to different types of experimental preeclampsia (replacement of drinking water with 1.8% NaCl from day 1 to 21 of gestation or intraperitoneal administration of non selective NO-synthase inhibitor L-NAME to pregnant rats in a daily dose of 25 mg/kg for 7 days on gestation days 14-20). Spatial memory was evaluated in an elevated 8-arm radial maze. Both types of experimental preeclampsia impaired spatial (long-term and short-term) memory and can be used in the development of drugs correcting negative effects of this pregnancy complication on memory. PMID- 27709386 TI - Inhibition of Apoptosis is a Potential Way to Improving Ischemic Brain Tolerance in Combined Exposure to Hypercapnia and Hypoxia. AB - We compared the intensity of apoptosis in the peri-infarction area of the brain after isolated and combined exposure to hypoxia and hypercapnia prior to focal ischemic stroke modeling. Hypoxia and hypercapnia reduced the number of TUNEL positive cells in the peri-infarction area, and their combination was most effective in comparison with effects of isolated exposures. The maximum neuroprotective effect of combined exposure to hypoxia and hypercapnia in comparison with isolated exposures was determined by inhibition of apoptosis in the peri-infarction zone. PMID- 27709387 TI - Dihydroquercetin Does Not Affect Age-Dependent Increase in Blood Pressure and Angiotensin-Converting Enzyme Activity in the Aorta of Hypertensive Rats. AB - We analyzed changes in angiotensin-converting enzyme activity in the aorta of hypertensive SHR rats against the background of age-related BP increase (from week 7 to 14) and the effect of dihydroquercetin on BP rise and angiotensin converting enzyme activity. Normotensive WKY rats of the same age were used as the control. BP and activity of angiotensin-converting enzyme in the aorta of SHR rats increased with age. Dihydroquercetin in doses of 100 and 300 MUg/kg per day had no effect on the increase of these parameters; dihydroquercetin administered to 14-week-old WKY rats in a dose of 300 MUg/kg reduced activity of the angiotensin-converting enzyme. Thus, the early (7-14 weeks) increase in BP and angiotensin-converting enzyme activity in the aorta of SHR rats was not modified by flavonoids (dihydroquercetin) in contrast to other rat strains and humans, which is indicative of specificity of hypertension mechanism in SHR rats. PMID- 27709388 TI - Effect of Hedgehog Signaling Pathway Activation on Proliferation of High-Grade Gliomas. AB - We studied the effect of an activator (ShTh) and an inhibitor (cyclopamine) of the Hedgehog signaling pathway on proliferation of human glioma cell lines U87-MG and U251-MG and cultured human astrocytes. The Hedgehog signaling pathway is activated in glioma cells, but not in cultured human astrocytes. Experiments with Shh and cyclopamine can serve as an additional criterion for assessing activity of Hedgehog signaling in known cell lines and primary cultured cells. PMID- 27709389 TI - Effect of ROS Inhalation on Systemic and Local Hemodynamics in Rats. AB - The effects of inhalation of singlet oxygen mixture, dry and humidified ozone oxygen mixture, and ozonated oils on heart rate variability as well as on the rate and control mechanisms of microcirculation were examined in rats. The most optimal were the responses of systemic and regional hemodynamics to inhalation of the gas produced by a generator of singlet oxygen and humidified ozone-oxygen mixtures. Singlet oxygen stabilized the cardiac rhythm and augmented microcirculation via activation of "internal" (endothelial and neurogenic) regulatory mechanisms. PMID- 27709390 TI - Audiovisual Stimulation Modulates Physical Performance and Biochemical and Hormonal Status of Athletes. AB - We studied the effect of audiovisual stimulation training course on physical development, functional state of the cardiovascular system, blood biochemical parameters, and hormonal status of athletes. The training course led to improvement of physical performance and adaptive capacities of the circulatory system, increase in plasma levels of total protein, albumin, and glucose and total antioxidant activity, and decrease in triglyceride, lipase, total bilirubin, calcium, and phosphorus. The concentration of hormones (cortisol, thyrotropin, triiodothyronine, and thyroxine) also decreased under these conditions. In the control group, an increase in the concentration of creatinine and uric acid and a tendency toward elevation of lowdensity lipoproteins and total antioxidant activity were observed in the absence of changes in cardiac function and physical performance; calcium and phosphorus concentrations reduced. The improvement in functional state in athletes was mainly associated with intensification of anabolic processes and suppression of catabolic reactions after audiovisual stimulation (in comparison with the control). Stimulation was followed by an increase in the number of correlations between biochemical and hormonal changes and physical performance of athletes, which attested to better integration of processes at the intersystem level. PMID- 27709391 TI - EEG-fMRI Study of Alpha-Stimulation Neurobiofeedback Training Course. AB - fMRI-EEG dynamics of brain activity in volunteers was studied during the course of EEG alpha-stimulation training (20 sessions). Twenty-three healthy men (20-35 years) were subjected to 3-fold mapping in a feedback loop (EEG alpha-rhythm biofeedback with acoustic reinforcement). This procedure was performed at the beginning, middle, and end of the course. During the first neurofeedback training session, deactivation (p<0.001) was found in the right angular gyrus, supramarginal, and superior temporal gyri, Brodmann area 39, and cerebellum. Activation (p<0.001) was observed in the medial frontal and cingulate gyri, motor areas of both hemispheres, and Brodmann area 32. During final (third) neurofeedback training session, we observed strong deactivation (p<0.05 with FDR) of zones responsible for spatial thinking and motor functions: left medial frontal and left medial temporal gyri; right postcentral, lingual, and superior frontal gyri; insula and right side of the cerebellum; and precuneus and cuneus (Brodmann areas 6, 9, 7, 31, 8, 13, and 22). Changes in the alpha wave power were most pronounced in the primary and secondary somatosensory cortex of the left hemisphere (Brodmann areas 2L and 5L). PMID- 27709392 TI - Functional State of the Heart during Spontaneous Nonconvulsive Seizure Activity at Various Times of the Day. AB - Circadian peculiarities of HR regulation and functional capacities of the heart in WAG/Rij rats with genetically determined absence epilepsy are related to spike wave activity of the brain. The number of spike-wave discharges (SWD) is maximum at night, early morning, and evening time and decreases to minimum at 08.00 16.00. At night, functional capacities of the heart are reduced and stress test at night induces ischemic changes in the myocardium at a lower functional load than in the daytime (low level of SWD activity). The decrease in the number of SWD and spike-wave index during the daytime contributes to the central mechanisms of autonomic regulation of the heart. However, these capacities are reduced against the background of increased seizure activity during nighttime. PMID- 27709393 TI - Immunotropic Properties of Immobilized Interferon-alpha2b.

PMID- 27709396 TI - Our genes, our selves: hereditary breast cancer and biological citizenship in Norway. AB - In this paper we explore the rise of 'the breast cancer gene' as a field of medical, cultural and personal knowledge. We address its significance in the Norwegian public health care system in relation to so-called biological citizenship in this particular national context. One of our main findings is that, despite its claims as a measure for health and disease prevention, gaining access to medical knowledge of BRCA 1/2 breast cancer gene mutations can also produce severe instability in the individuals and families affected. That is, although gene testing provides modern subjects with an opportunity to foresee their biological destiny and thereby become patients in waiting, it undoubtedly also comes with difficult existential dilemmas and choices, with implications that resonate beyond the individual and into different family and love relations. By elaborating on this finding we address the question of whether the empowerment slogan, which continues to be advocated through various health, BRCA and breast cancer discourses, reinforces a naive or an idealized notion of the actively responsible patient: resourceful enough to seek out medical expertise and gain sufficient knowledge, on which to base informed decisions, thereby reducing the future risk of developing disease. In contrast to this ideal, our Norwegian informants tell a different story, in which there is no apparent heroic mastery of genetic fates, but rather a pragmatic attitude to dealing with a dire situation over which they have little control, despite having complied with medical advice through national guidelines and follow-up procedures for BRCA 1/2 carriers. In conclusion we claim that the sense of safety that gene testing and its associated medical solutions allegedly promise to provide proved illusory. Although BRCA-testing offers the potential for protection from adverse DNA heritage, administered through possibilities for self-monitoring and self management of the body, the feeling of 'being in good health' has hardly been reinforced by the emergence of gene technology. PMID- 27709397 TI - Large-scale monitoring of effects of clothianidin-dressed oilseed rape seeds on pollinating insects in Northern Germany: effects on red mason bees (Osmia bicornis). AB - The aim of this study was to investigate the effects of Elado(r) (10 g clothianidin & 2 g beta-cyfluthrin/kg seed)-dressed oilseed rape on the development and reproduction of mason bees (Osmia bicornis) as part of a large scale monitoring field study in Northern Germany, where oilseed rape is usually cultivated at 25-33 % of the arable land. Both reference and test sites comprised 65 km2 in which no other crops attractive to pollinating insects were present. Six study locations were selected per site and three nesting shelters were placed at each location. Of these locations, three locations were directly adjacent to oilseed rape fields, while the other three locations were situated 100 m distant from the nearest oilseed rape field. At each location, 1500 cocoons of O. bicornis were placed into the central nesting shelter. During the exposure phase, nest building activities and foraging behaviour were assessed repeatedly. Cocoons were harvested in autumn to assess parasitization and reproduction including larval development. The following spring, the emergence of the next generation of adults from cocoons was monitored. High reproductive output and low parasitization rates indicated that Elado(r)-dressed oilseed rape did not cause any detrimental effects on the development or reproduction of mason bees. PMID- 27709395 TI - Antimicrobial susceptibility and phylotyping profile of pathogenic Escherichia coli and Salmonella enterica isolates from calves and pigs in Minas Gerais, Brazil. AB - The aims of the present study were to determine (i) the profiles of phylogroup and (ii) the antimicrobial susceptibility of pathogenic Escherichia coli strains isolated from calves, and of Salmonella spp. strains isolated from calves and pigs in Minas Gerais State, Brazil. Sixty-one pathogenic E. coli strains and Salmonella spp. (n = 24) strains isolated from fecal samples of calves and Salmonella spp. (n = 39) strains previously isolated from fecal samples of growing/finishing pigs were tested. The minimum inhibitory concentration (MIC) using the agar dilution method was determined for nalidixic acid, amikacin, amoxicillin, ampicillin, cefoxitin, norfloxacin, gentamicin, tetracycline, and trimethoprim-sulfamethoxazole. All E. coli isolates were susceptible to amikacin. Tetracycline was the antimicrobial that presented the higher frequency of resistance among E. coli strains, followed by ampicillin, trimethoprim sulfamethoxazole, amoxicillin, nalidixic acid, norfloxacin, gentamicin, and cefoxitin. E. coli (n = 61) strains isolated from calves belonged to different phylogroup namely, phylogroup A (n = 26), phylogroup B1 (n = 31), phylogroup E (n = 3), and phylogroup F (n = 1). Phylogroups B2, C, and D were not identified among the E. coli in the present study. All Salmonella spp. (n = 24) strains isolated from fecal samples of calves were susceptible to amikacin, amoxicillin, ampicillin, norfloxacin, gentamicin, tetracycline, and trimethoprim sulfamethoxazole. Resistance to nalidixic acid and cefoxitin was detected in 16.66 and 8.33 % of the Salmonella spp. strains, respectively. Among the Salmonella spp. (n = 39) strains isolated from fecal samples of pigs, the higher frequency of resistance was observed to tetracycline, followed by amoxicillin, gentamicin, ampicillin, trimethoprim-sulfamethoxazole, nalidixic acid, cefoxitin, and norfloxacin. All strains were susceptible to amikacin. Forty-eight (78.68 %) of the E. coli strains were classified as multidrug-resistant, whereas among Salmonella spp. strains, the percentage of multidrug resistance was 57.14 %, being all multidrug-resistant strains isolated from pigs (92.30 %). The results from the present study indicate a high frequency of antimicrobial resistance among pathogenic E. coli strains isolated from calves and Salmonella spp. strains isolated from pigs and a high rate of susceptibility to most antimicrobials tested among Salmonella spp. strains isolated from calves. Our study highlights the presence of multidrug-resistant strains of E. coli and Salmonella spp. isolated from food-producing animals in Minas Gerais, Brazil. PMID- 27709398 TI - Joint toxicity of cadmium and SDBS on Daphnia magna and Danio rerio. AB - Information on joint toxicity is limited. To clarify the joint toxicity and the interactions among toxicants on different aquatic organisms, we investigated the acute toxicity of cadmium and sodium dodecyl benzene sulfonate, two chemicals with high concerns in Chinese waters, on the immobilization of Daphnia magna (D. magna) and the swimming behavior of Danio rerio (D. rerio). Our results illustrated that cadmium and sodium dodecyl benzene sulfonate expressed a synergistic effect on the immobilization of D. magna; and an antagonistic effect on the swimming speed D. rerio, but a synergistic effect on its vertical position in the water column. Based on the observed data, we found the independent action model was more appropriate than the concentration addition model in the prediction of their joint toxicity. Our results gave an example of the joint toxicity investigation, and aided to comprehensive the toxicity action mode of chemical mixtures. PMID- 27709399 TI - Review of field and monitoring studies investigating the role of nitro substituted neonicotinoid insecticides in the reported losses of honey bee colonies (Apis mellifera). AB - The nitro-substituted neonicotinoid insecticides, which include imidacloprid, thiamethoxam and clothianidin, are widely used to control a range of important agricultural pests both by foliar applications and also as seed dressings and by soil application. Since they exhibit systemic properties, exposure of bees may occur as a result of residues present in the nectar and/or pollen of seed- or soil-treated crop plants and so they have been the subject of much debate about whether they cause adverse effects in pollinating insects under field conditions. Due to these perceived concerns, the use of the three neonicotinoids imidacloprid, clothianidin and thiamethoxam has been temporarily suspended in the European Union for seed treatment, soil application and foliar treatment in crops attractive to bees. Monitoring data from a number of countries are available to assess the presence of neonicotinoid residues in honey bee samples and possible impacts at the colony level and these are reviewed here together with a number of field studies which have looked at the impact of clothiandin on honey bees in relation to specific crop use and in particular with oilseed rape. Currently there is considerable uncertainty with regards to the regulatory testing requirements for field studies. Accordingly, a testing protocol was developed to address any acute and chronic risks from oilseed rape seeds containing a coating with 10 g clothianidin and 2 g beta-cyfluthrin per kg seeds (Elado(r)) for managed honey bee (Apis mellifera) colonies, commercially bred bumble bee (Bombus terrestris) colonies and red mason bees (Osmia bicornis) as a representative solitary bee species. This is described here together with a summary of the results obtained as an introduction to the study details given in the following papers in this issue. PMID- 27709400 TI - Identification and characterization of an isolate of apple green crinkle associated virus involved in a severe disease of quince (Cydonia oblonga, Mill.). AB - A quince tree showing severe symptoms of a previously undescribed viral disease occurring in northern Apulia (Italy) was analysed using high-throughput sequencing of small RNA libraries, leading to the identification of a new strain of apple green crinkle associated virus (isolate AGCaV-CYD) showing peculiar traits. RT-PCR with specific primers detected AGCaV-CYD in consistent association with symptoms in the surveyed orchards. Molecular characterization of the reconstructed genome, together with phylogenetic analysis, showed it to be closely related to an AGCaV strain causing green crinkle disease in apple (AGCaV AUR) and divergent from the type strain of apple stem pitting virus (ASPV-PA66). PMID- 27709402 TI - Molecular characterization of a new human coxsackievirus B2 associated with severe hand-foot-mouth disease in Yunnan Province of China in 2012. AB - Human coxsackievirus B2 (CVB2) belongs to the species Human enterovirus B and can cause aseptic meningitis, myocarditis and hand-foot-mouth disease (HFMD). We first determined the complete genome of the RW41-2/YN/CHN/2012 strain, isolated from a patient with HFMD and aseptic meningitis in the Yunnan Province, China in 2012. The strain shared 83.5 % and 82.2 % nucleotide similarity with CVB2 prototype strain Ohio-1, in the complete VP1 gene and the complete genome, respectively. Using phylogenetic and homogeneity analyses for the complete VP1 gene, CVB2 strains could be divided into four genogroups (A-D); the RW41 2/YN/CHN/2012 strain belonging to genogroup D. The amino acid sequence of VP1 is highly conserved. Recombination analyses showed the newly isolated RW41 2/YN/CHN/2012 strain was probably a recombinant, which was closely related to strain CVB2 (KM386639) in the genomic P1 and P2 regions and strains of other human enterovirus B (HEV-B) viruses (KT353721, JX644073, and KP262053) in the P3 region. PMID- 27709401 TI - Construction of a recombinant duck enteritis virus vaccine expressing hemagglutinin of H9N2 avian influenza virus and evaluation of its efficacy in ducks. AB - H9 subtype avian influenza viruses (AIVs) remain a significant burden in the poultry industry and are considered to be one of the most likely causes of any new influenza pandemic in humans. As ducks play an important role in the maintenance of H9 viruses in nature, successful control of the spread of H9 AIVs in ducks will have significant beneficial effects on public health. Duck enteritis virus (DEV) may be a promising candidate viral vector for aquatic poultry vaccination. In this study, we constructed a recombinant DEV, rDEV-?UL2 HA, inserting the hemagglutinin (HA) gene from duck-origin H9N2 AIV into the UL2 gene by homologous recombination. One-step growth analyses showed that the HA gene insertion had no effect on viral replication and suggested that the UL2 gene was nonessential for virus growth in vitro. In vivo tests further showed that the insertion of the HA gene in place of the UL2 gene did not affect the immunogenicity of the virus. Moreover, a single dose of 103 TCID50 of rDEV-?UL2 HA induced solid protection against lethal DEV challenge and completely prevented H9N2 AIV viral shedding. To our knowledge, this is the first report of a DEV vectored vaccine providing robust protection against both DEV and H9N2 AIV virus infections in ducks.

AB - Although multiple forms (i.e., physical, threatening, psychological, sexual, and relational abuse) and patterns (i.e., perpetration and victimization) of violence can co-occur, most existing research examines these experiences individually. Thus, the purpose of this study is to investigate: (1) homogenous subgroups based on victimization and perpetration of multiple forms of teen dating violence; (2) predictors of membership in these subgroups; and (3) mental health consequences associated with membership in each subgroup. Nine hundred eighteen adolescents in the 9th or 10th grade at seven public high schools in Texas participated in the survey (56 % female, White: 30 %, Hispanic: 32 %, African American: 29 %, others: 9 %). A three-step latent class analysis was employed. Five latent teen dating violence classes were identified: (1) nonviolence; (2) emotional/verbal abuse; (3) forced sexual contact; (4) psychological + physical violence; and (5) psychological abuse. Females, African Americans, and youth who had higher acceptance of couple violence scores and whose parents had less education were more likely to members of dating violence classes compared with the nonviolence class. Adolescents who experienced multiple types of dating violence reported greater mental health concerns. Prevention programs may benefit by identifying the homogenous subgroups of teen dating violence and targeting adolescent teen dating violence accordingly. PMID- 27709403 TI - Variation in the Types of Providers Participating in Breast Cancer Follow-Up Care: A SEER-Medicare Analysis. AB - BACKGROUND: The current guidelines do not delineate the types of providers that should participate in early breast cancer follow-up care (within 3 years after completion of treatment). This study aimed to describe the types of providers participating in early follow-up care of older breast cancer survivors and to identify factors associated with receipt of follow-up care from different types of providers. METHODS: Stages 1-3 breast cancer survivors treated from 2000 to 2007 were identified in the Surveillance, Epidemiology and End results Medicare database (n = 44,306). Oncologist (including medical, radiation, and surgical) follow-up and primary care visits were defined using Medicare specialty provider codes and linked American Medical Association (AMA) Masterfile. The types of providers involved in follow-up care were summarized. Stepped regression models identified factors associated with receipt of medical oncology follow-up care and factors associated with receipt of medical oncology care alone versus combination oncology follow-up care. RESULTS: Oncology follow-up care was provided for 80 % of the patients: 80 % with a medical oncologist, 46 % with a surgeon, and 39 % with a radiation oncologist after radiation treatment. The patients with larger tumor size, positive axillary nodes, estrogen receptor (ER)-positive status, and chemotherapy treatment were more likely to have medical oncology follow-up care than older patients with higher Charlson comorbidity scores who were not receiving axillary care. The only factor associated with increased likelihood of follow-up care with a combination of oncology providers was regular primary care visits (>2 visits/year). CONCLUSIONS: Substantial variation exists in the types of providers that participate in breast cancer follow-up care. Improved guidance for the types of providers involved and delineation of providers' responsibilities during follow-up care could lead to improved efficiency and quality of care. PMID- 27709406 TI - Preliminary Effectiveness Study of Coping Power Program for Aggressive Children in Pakistan. AB - Aggression is a characteristic feature of many psychiatric disorders. To address the scarceness for evidence-based interventions for behavioral problems in Pakistan, we evaluated the effectiveness of culturally adapted version of Coping Power Program. The purpose of the study was to determine the extent to which Coping Power Program is capable of reducing aggressive behavior and improving competent behavior, when delivered in a different culture, i.e., Pakistan. With randomized control trial (RCT) of pre- and post-testing, 112 fourth grade boys were allocated to Coping Power intervention condition and waitlist control condition. The intervention group showed significant reduction in aggression at post assessment, in comparison to control group. Boys who received Coping Power intervention also showed improvements in behavior, social skills, and social cognitive processes, with better anger control and problem solving strategies, in comparison to the control group. The results of the study provide preliminary evidence, supporting the effectiveness of Coping Power Program for Pakistani children. Despite its limitations, the results of this study are promising and suggest that Coping Power is an effective intervention to reduce behavioral problems and promote healthy and positive behaviors in children, even when implemented in different contexts with greater potential for violence exposure. PMID- 27709407 TI - Sulfated glycosaminoglycans: their distinct roles in stem cell biology. AB - Sulfated glycosaminoglycan (GAG) chains are a class of long linear polysaccharides that are covalently attached to multiple core proteins to form proteoglycans (PGs). PGs are major pericellular and extracellular matrix components that surround virtually all mammalian cell surfaces, and create conducive microenvironments for a number of essential cellular events, such as cell adhesion, cell proliferation, differentiation, and cell fate decisions. The multifunctional properties of PGs are mostly mediated by their respective GAG moieties, including chondroitin sulfate (CS), heparan sulfate (HS), and keratan sulfate (KS) chains. Structural divergence of GAG chains is enzymatically generated and strictly regulated by the corresponding biosynthetic machineries, and is the major driving force for PG functions. Recent studies have revealed indispensable roles of GAG chains in stem cell biology and technology. In this review, we summarize the current understanding of GAG chain-mediated stem cell niches, focusing primarily on structural characteristics of GAG chains and their distinct regulatory functions in stem cell maintenance and fate decisions. PMID- 27709408 TI - Coupling of shear-circumferential stress pulses investigation through stress phase angle in FSI models of stenotic artery using experimental data. AB - Many cardiovascular diseases are closely associated with hemodynamic parameters. The main purpose of this study is mimicking a physiological blood flow in stenotic arteries to provide an understanding of hemodynamic parameters. An experimental setup was designed to produce original pulsatile flow and measure pressure pulse waves through a compliant tube. Moreover, a numerical model considering fluid-solid interaction was developed to investigate wall shear stress and circumferential stress waves, based on the results of the experiments. Results described elevated mean pressure by increasing stenosis severity especially at the critical obstacle of 50 %, which the pressure rose significantly and raised up by 10 mm Hg that may cause damage in endothelial cells. Increasing in stenosis severity led to: more negative wall shear stress and more oscillation of shear stress at the post-stenotic region and also more absolute value of angular phase difference between wall shear stress and circumferential stress waves at the stenotic throat. All of the aforementioned parameters determinant the endothelial cell pathology in predication of potential sites of progression of atherosclerotic plaques. Therefore, results can be applied in study of plaque growth and mechanisms of arterial remodeling in atherosclerosis. PMID- 27709410 TI - Innervation of the blood vessels of the spinal cord: a comprehensive review. AB - There is growing evidence that the nervous system influences spinal cord vasculature. However, most descriptions of the spinal cord have paid little attention to this important aspect. We reviewed the literature on the innervation of spinal cord vessels with an emphasis on findings that may be applicable to human medicine. Multiple neurotransmitters and competing theories have been implicated in the neural regulation of spinal cord blood vessels. Identifying valid mechanisms of pathogenesis could be beneficial to human patients with spinal cord lesions. We discuss the various findings on the neural mechanisms behind spinal cord blood flow. Further investigation is warranted due to the current emphasis on comparative animal studies without corresponding corroborative human findings. PMID- 27709411 TI - Patterns of Vasculature in Mouse Models of Lung Cancer Are Dependent on Location. AB - PURPOSE: Preclinical studies of hypoxia are generally done using ectopic xenograft tumors, which behave differently from human tumors. Our previous findings have shown that subcutaneously implanted lung tumors exhibit more hypoxia than their orthotopic implanted or spontaneous K-ras-induced counterparts. We hypothesize that differences in hypoxia are due to site-specific differences in vascularity and perfusion. PROCEDURES: To compare the presence and functionality of vessels in these tumor models, we studied vascular perfusion in vivo in real time. RESULTS: Orthotopically implanted and spontaneous K-ras induced lung tumors showed elevated perfusion, demonstrating vasculature functionality. Little contrast agent uptake was observed within the subcutaneously implanted tumors, indicating vascular dysfunction. These findings were corroborated at the microscopic level with Hoechst 33342 and Meca-32 staining. CONCLUSIONS: From these observations, we concluded that differences in hypoxia in experimental models is related to vessel perfusion. Thus, appropriate selection of preclinical lung tumor models is essential for the study of hypoxia, angiogenesis and therapies targeting these phenomena. PMID- 27709412 TI - Acromegalic osteopathy. AB - Acromegalic osteopathy is an emerging complication of acromegaly characterized by increase in bone turnover, deterioration in bone microarchitecture and high risk of vertebral fractures. Vertebral fractures, as diagnosed by a radiological and morphometric approach, occur in about one-third of acromegaly patients in close relationship with duration of active disease. However, the prediction of vertebral fractures in this clinical setting is still a matter of uncertainty, since the pathogenesis of acromegalic osteopathy is multifactorial and fractures may occur even in presence of normal bone mineral density. In this narrative article, we summarize the pathophysiology and clinical aspects of acromegalic osteopathy. PMID- 27709409 TI - Radiation-induced gliomas: a comprehensive review and meta-analysis. AB - By conducting a systemic search of the PubMed database, we performed a comprehensive literature review to characterize secondary gliomas following radiotherapy treatment and to determine the most appropriate treatment strategy. Our analysis included 296 cases of radiation-induced gliomas. The primary lesion was characterized as a hematological malignancy in 104 cases (35.1 %), pituitary adenoma in 35 (11.8 %), craniopharyngioma in 19 (6.4 %), medulloblastoma in 38 (12.8 %), germ cell tumor in 13 (4.3 %), low-grade glioma in 28 (9.4 %), cancer/sarcoma in 12 (4.0 %), scalp region disease in 15 (5.0 %), meningioma/schwannoma in 13 (4.3 %), metastatic brain tumor in 5 (1.6 %), and other types (e.g., arteriovenous malformations and angiomas) in 14 (4.7 %). The average age of onset for primary lesions was 16.0 +/- 15.8 years, and the average radiation dose delivered to the primary lesion was 37.6 +/- 20.0 Gy. Secondary gliomas could be divided into grade I (1), grade II (32), grade III (88), and grade IV (173) tumors. The median overall survival for all glioma cases was 11 months (95 % confidence interval [CI], 9-12), with a 2-year survival rate of 20.2 %. On multivariate analysis, combined modality treatment and the latency period from the radiotherapy treatment to the glioma diagnosis were variables associated with the overall survival of patients with grade III/IV secondary gliomas. For patients treated with cranial radiotherapy, the risk of secondary glioma incidence warrants a longer follow-up period beyond the standard time frame typically designated for determining the risk of primary tumor relapse. Moreover, combination therapy is a potential treatment option for radiation-induced gliomas. PMID- 27709413 TI - Immune Cell Metabolism in Systemic Lupus Erythematosus. AB - Cellular metabolism represents a newly identified checkpoint of effector functions in the immune system. A solid body of work has characterized the metabolic requirements of normal T cells during activation and differentiation into polarized effector subsets. Similar studies have been initiated to characterize the metabolic requirements for B cells and myeloid cells. Only a few studies though have characterized the metabolism of immune cells in the context of autoimmune diseases. Here, we review what is known on the altered metabolic patterns of CD4+ T cells, B cells, and myeloid cells in lupus patients and lupus prone mice and how they contribute to lupus pathogenesis. We also discuss how defects in immune metabolism in lupus can be targeted therapeutically. PMID- 27709415 TI - Pathology of Human Pheochromocytoma and Paraganglioma Xenografts in NSG Mice. AB - A major impediment to the development of effective treatments for metastatic or unresectable pheochromocytomas and paragangliomas has been the absence of valid models for pre-clinical testing. Attempts to establish cell lines or xenografts from human pheochromocytomas and paragangliomas have previously been unsuccessful. NOD-scid gamma (NSG) mice are a recently developed strain lacking functional B-cells, T-cells, and NK cells. We report here that xenografts of primary human paragangliomas will take in NSG mice while maintaining their architectural and immunophenotypic characteristics as expressed in the patients. In contrast to grafts of cell lines and of most common types of primary tumors, the growth rate of grafted paragangliomas is very slow, accurately representing the growth rate of most pheochromocytomas and paragangliomas even in metastases in humans. Although the model is therefore technically challenging, primary patient-derived xenografts of paragangliomas in NSG mice provide a potentially valuable new tool that could prove especially valuable for testing treatments aimed at eradicating the small tumor deposits that are often numerous in patients with metastatic paraganglioma. PMID- 27709414 TI - Sensing photosynthetic herbicides in an electrochemical flow cell. AB - Specific inhibitory reactions of herbicides with photosynthetic reaction centers bound to working electrodes were monitored in a conventional electrochemical cell and a newly designed microfluidic electrochemical flow cell. In both cases, the bacterial reaction centers were bound to a transparent conductive metal oxide, indium-tin-oxide, electrode through carbon nanotubes. In the conventional cell, photocurrent densities of up to a few MUA/cm2 could be measured routinely. The photocurrent could be blocked by the photosynthetic inhibitor terbutryn (I 50 = 0.38 +/- 0.14 MUM) and o-phenanthroline (I 50 = 63.9 +/- 12.2 MUM). The microfluidic flow cell device enabled us to reduce the sample volume and to simplify the electrode arrangement. The useful area of the electrodes remained the same (ca. 2 cm2), similar to the classical electrochemical cell; however, the size of the cell was reduced considerably. The microfluidic flow control enabled us monitoring in real time the binding/unbinding of the inhibitor and cofactor molecules at the secondary quinone site. PMID- 27709416 TI - 1H, 15N and 13C resonance assignments for free and IEEVD peptide-bound forms of the tetratricopeptide repeat domain from the human E3 ubiquitin ligase CHIP. AB - The ubiquitin ligase CHIP catalyzes covalent attachment of ubiquitin to unfolded proteins chaperoned by the heat shock proteins Hsp70/Hsc70 and Hsp90. CHIP interacts with Hsp70/Hsc70 and Hsp90 by binding of a C-terminal IEEVD motif found in Hsp70/Hsc70 and Hsp90 to the tetratricopeptide repeat (TPR) domain of CHIP. Although recruitment of heat shock proteins to CHIP via interaction with the CHIP TPR domain is well established, alterations in structure and dynamics of CHIP upon binding are not well understood. In particular, the absence of a structure for CHIP-TPR in the free form presents a significant limitation upon studies seeking to rationally design inhibitors that may disrupt interactions between CHIP and heat shock proteins. Here we report the 1H, 13C, and 15N backbone and side chain chemical shift assignments for CHIP-TPR in the free form, and backbone chemical shift assignments for CHIP-TPR in the IEEVD-bound form. The NMR resonance assignments will enable further studies examining the roles of dynamics and structure in regulating interactions between CHIP and the heat shock proteins Hsp70/Hsc70 and Hsp90. PMID- 27709417 TI - Reformation of tissue balls from tentacle explants of coral Goniopora lobata: self-organization process and response to environmental stresses. AB - Coral has strong regeneration ability, which has been applied for coral production and biodiversity protection via tissue ball (TB) culture. However, the architecture, morphological processes, and effects of environmental factors on TB formation have not been well investigated. In this study, we first observed TB formation from the cutting tentacle of scleractinia coral Goniopora lobata and uncovered its inner organization and architecture by confocal microscopy. We then found that the cutting tentacle TB could self-organize and reform a solid TB (sTB) in the culture media. Using chemical drug treatment and dissection manipulation approaches, we demonstrated that the mechanical forces for bending and rounding of the cutting fragments came from the epithelial cells, and the cilia of epithelial cell played indispensable roles for the rounding process. Environmental stress experiments showed that high temperature, not CO2-induced acidification, affected TB and sTB formation. However, the combination of high temperature and acidification caused additional severe effects on sTB reformation. Our studies indicate that coral TB has strong regeneration ability and therefore could serve as a new model to further explore the molecular mechanism of TB formation and the effects of environmental stresses on coral survival and regeneration.

PMID- 27709418 TI - Proliferation of rabbit chondrocyte and inhibition of IL-1beta-induced apoptosis through MEK/ERK signaling by statins. AB - Chondrocyte plays a critical role in endochondral ossification and cartilage repair by maintaining the cartilaginous matrix. Statins have been widely used to lower the cholesterol level in patients with cardiovascular disorders. Previous research has demonstrated potential role of statins in chondrocyte proliferation. This study addresses the proliferation-regulatory effect of lovastatin in rabbit chondrocytes as well as the underlying signaling mechanisms, thereby exploring its potential application in chondrocyte-related disorders, such as cartilage damage and osteoarthritis. Rabbit chondrocytes were treated with lovastatin at multiple concentrations, and the proliferation rate was measured by CCK-8 test. The results showed significant increase in chondrocyte proliferation under lovastatin treatment. Using real-time quantitative PCR, it was observed that the expression levels of COL2A1, SOX-9, Caspase-3, and MMP-3 genes were significantly changed by lovastatin treatment. Western blotting analysis showed that the abundance of COL2A1, SOX-9, MEK1/2, p-MEK1/2, ERK1/2, p-ERK1/2, Caspase-3, and MMP-3 proteins was also significantly influenced by lovastatin treatment. Interleukine-1 beta (IL-1beta) is involved in the progression of osteoarthritis (OA) by inducing articular cartilage and chondrocyte aging and senescence. In this study, we observed that lovastatin treatment inhibited IL-1beta-induced chondrocyte apoptosis, while the combined treatment of lovastatin and U0126 evidently offset the apoptosis-inhibiting effect of lovastatin in chondrocyte proliferation. The expressional level and protein abundance of COL2A1, SOX-9, MEK1/2, p-MEK1/2, ERK1/2, p-ERK1/2, caspase-3, and MMP-3 genes showed significant alterations under the combined treatment. Together, our results suggested that lovastatin significantly promoted proliferation and inhibited the IL-1beta induced apoptosis in rabbit chondrocytes, which was mediated by the MEK/ERK signaling.

PMID- 27709423 TI - Kampo formula "Hochu-ekki-to" suppressed carbon tetrachloride-induced hepatotoxicity in mice. AB - OBJECTIVE: The aim of this study was to investigate whether pretreatment with the Japanese herbal medicine "Hochu-ekki-to" (TJ-41) has an ameliorative effect on carbon tetrachloride (CCl4)-induced hepatotoxicity through anorexia prevention. METHODS: Twenty-four hours before CCl4 injection, TJ-41 or saline solution was intraperitoneally administered. Furthermore, 24 h after TJ-41 injection, mice were intraperitoneally administered 1.6 g/kg CCl4 or olive oil. Moreover, 24 h after CCl4/olive oil injection, mice from each group were euthanized and bled for plasma analysis. RESULTS: Mice injected with CCl4 exhibited severe anorexia. Moreover, CCl4 increased the plasma levels of hepatic injury markers (i.e., alanine aminotransferase and aspartate aminotransferase) as well as lipid peroxidation and hepatic Ca levels. Pretreatment with TJ-41 recovered the CCl4 induced anorexia and plasma levels of the hepatic injury markers. Moreover, CCl4 induced lipid peroxidation and hepatic Ca levels decreased upon TJ-41 pretreatment. In addition, hepatic metallothionein levels in the TJ-41 + CCl4 treated group were decreased by >50 % compared with the levels in the TJ-41 treated group, implying that metallothionein was consumed by CCl4-induced radicals. CONCLUSION: Our results suggest that TJ-41 attenuates CCl4-induced hepatotoxicity, presumably by the induction of metallothionein, which in turn scavenges radicals induced by CCl4 exposure. PMID- 27709424 TI - Gastrointestinal microbiome and breast cancer: correlations, mechanisms and potential clinical implications. AB - Gastrointestinal microbiome plays as a symbiont which provides protection effect against invading pathogens, aids in the immune system development, nutrient reclamation and absorption as well as molecule breakdown. And it may avert carcinogenesis through these biological activities. By now, studies have been carried out to elaborate the association between gastrointestinal microbiome and breast cancer. It has been implicated that breast cancer was substantially associated with estrogen-dependent and estrogen-independent functions of gastrointestinal microbiome. Evidence from animal experiments also confirmed mammary tumor-related changes in microbial community. The possible mechanisms involve estrogen metabolism, immune regulation, obese status and so forth. Based on the current evidence, cues on future management strategies of breast cancer such as antibiotics and dietary interventions are proposed. In conclusion, large scale clinical studies and bench-based researches are needed to validate the associations and elaborate the mechanisms, so as to reduce the risk of breast cancer and improve the outcomes of those already diagnosed. PMID- 27709422 TI - How Does the dGEMRIC Index Change After Surgical Treatment for FAI? A Prospective Controlled Study: Preliminary Results. AB - BACKGROUND: Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) allows an objective, noninvasive, and longitudinal quantification of biochemical cartilage properties. Although dGEMRIC has been used to monitor the course of cartilage degeneration after periacetabular osteotomy (PAO) for correction of hip dysplasia, such longitudinal data are currently lacking for femoroacetabular impingement (FAI). QUESTIONS/PURPOSES: (1) How does the mean acetabular and femoral dGEMRIC index change after surgery for FAI at 1-year followup compared with a similar group of patients with FAI treated without surgery? (2) Does the regional distribution of the acetabular and femoral dGEMRIC index change for the two groups over time? (3) Is there a correlation between the baseline dGEMRIC index and the change of patient-reported outcome measures (PROMs) at 1-year followup? (4) Among those treated surgically, can dGEMRIC indices distinguish between intact and degenerated cartilage? METHODS: We performed a prospective, comparative, nonrandomized, longitudinal study. At the time of enrollment, the patients' decision whether to undergo surgery or choose nonoperative treatment was not made yet. Thirty-nine patients (40 hips) who underwent either joint preserving surgery for FAI (20 hips) or nonoperative treatment (20 hips) were included. The two groups did not differ regarding Tonnis osteoarthritis score, preoperative PROMs, or baseline dGEMRIC indices. There were more women (60% versus 30%, p = 0.003) in the nonoperative group and patients were older (36 +/- 8 years versus 30 +/- 8 years, p = 0.026) and had lower alpha angles (65 degrees +/- 10 degrees versus 73 degrees +/- 12 degrees , p = 0.022) compared with the operative group. We used a 3.0-T scanner and a three-dimensional dual flip-angle gradient-echo technique for the dGEMRIC technique for the baseline and the 1-year followup measurements. dGEMRIC indices of femoral and acetabular cartilage were measured separately on the initial and followup radial dGEMRIC reformats in direct comparison with morphologic radial images. Regions of interest were placed manually peripherally and centrally within the cartilage based on anatomic landmarks at the clockface positions. The WOMAC, the Hip disability and Osteoarthritis Outcome Score, and the modified Harris hip score were used as PROMs. Among those treated surgically, the intraoperative damage according to the Beck grading was recorded and compared with the baseline dGEMRIC indices. RESULTS: Although both the operative and the nonoperative groups experienced decreased dGEMRIC indices, the declines were more pronounced in the operative group (-96 +/- 112 ms versus -16 +/- 101 ms on the acetabular side and -96 +/- 123 ms versus -21 +/- 83 ms on the femoral side in the operative and nonoperative groups, respectively; p < 0.001 for both). Patients undergoing hip arthroscopy and surgical hip dislocation experienced decreased dGEMRIC indices; the decline in femoral dGEMRIC indices was more pronounced in hips after surgical hip dislocation (-120 +/- 137 ms versus -61 +/- 89 ms, p = 0.002). In the operative group a decline in dGEMRIC indices was observed in 43 of 44 regions over time. In the nonoperative group a decline in dGEMRIC indices was observed in four of 44 regions over time. The strongest correlation among patients treated surgically was found between the change in WOMAC and baseline dGEMRIC indices for the entire joint (R = 0.788, p < 0.001). Among those treated nonoperatively, no correlation between baseline dGEMRIC indices and change in PROMs was found. In the posterosuperior quadrant, the dGEMRIC index was higher for patients with intact cartilage compared with hips with chondral lesions (592 +/- 203 ms versus 444 +/- 205 ms, p < 0.001). CONCLUSIONS: We found a decline in acetabular, femoral, and regional dGEMRIC indices for the surgically treated group at 1-year followup despite an improvement in all PROMs. We observed a similar but less pronounced decrease in the dGEMRIC index in symptomatic patients without surgical treatment indicating continuous cartilage degeneration. Although treatment of FAI is intended to alter the forces acting across the hip by eliminating impingement, its effects on cartilage biology are not clear. dGEMRIC provides a noninvasive method of assessing these effects. Longer term studies will be needed to determine whether the matrix changes of the bradytrophic cartilage seen here are permanent or clinically important. LEVEL OF EVIDENCE: Level II, therapeutic study. PMID- 27709425 TI - Epigenome-wide DNA methylation analysis in siblings and monozygotic twins discordant for sporadic Parkinson's disease revealed different epigenetic patterns in peripheral blood mononuclear cells. AB - Numerous studies have elucidated the genetics of Parkinson's disease; however, the aetiology of the majority of sporadic cases has not yet been resolved. We hypothesized that epigenetic variations could be associated with PD and evaluated the DNA methylation pattern in PD patients compared to brothers or twins without PD. The methylation of DNA from peripheral blood mononuclear cells of 62 discordant siblings including 24 monozygotic twins was characterized with Illumina DNA Methylation 450K bead arrays and subsequently validated in two independent cohorts: 221 PD vs. 227 healthy individuals (cohort 1) applying Illumina's VeraCode and 472 PD patients vs. 487 controls (cohort 2) using pyrosequencing. We choose a delta beta of >15 % and selected 62 differentially methylated CpGs in 51 genes from the discordant siblings. Among them, three displayed multiple CpGs per gene: microRNA 886 (MIR886, 10 CpGs), phosphodiesterase 4D (PDE4D, 2 CpGs) and tripartite motif-containing 34 (TRIM34, 2 CpGs). PDE4D was confirmed in both cohorts (p value 2.44e-05). In addition, for biomarker construction, we used the penalized logistic regression model, resulting in a signature of eight CpGs with an AUC of 0.77. Our findings suggest that a distinct level of PD susceptibility stems from individual, epigenetic modifications of specific genes. We identified a signature of CpGs in blood cells that could separate control from disease with a reasonable discriminatory power, holding promise for future epigenetically based biomarker development. PMID- 27709427 TI - S-100 Negative Granular Cell Tumor (So-called Primitive Polypoid Non-neural Granular Cell Tumor) of the Oral Cavity. AB - Four cases of cutaneous S-100 negative granular cell tumor were described in 1991. Until now, only 3 cases of oral involvement have been documented in English literature. Two additional cases of oral S-100 negative granular cell tumor are described. Immunohistochemical markers were applied to exclude other lesions that may show the presence of granular cells. The clinical findings were correlated with the histopathological and immunohistochemical features to arrive at the appropriate diagnosis. S-100 negative granular cell tumors are erythematous polypoid masses commonly mistaken for granulation tissue or a pyogenic granuloma. Any part of the oral cavity may be affected. Histopathologically, the lesions consist of sheets, nests, and fascicles of granular cells that are S-100 negative. The granular cells are non-reactive to SMA, HMB45, Melan A, and CD163. The intracytoplasmic granules are diffusely and strongly positive to NKI/C3. The cell lineage of the S-100 negative granular cell tumor is obscure. Absence of staining with CD163 excludes a histiocytic lineage. Absence of staining with S 100 excludes a neural origin. Absence of staining with S-100 and key melanoma markers HMB45 and Melan A also excludes a melanocytic origin. In this context, positive reactivity with NKI/C3 is indicative of presence of intracytoplasmic lysosomal granules only. Greater awareness of this lesion in the oral cavity will result in better characterization of its biologic potential. PMID- 27709426 TI - Diet, gut microbiota and cognition. AB - The consumption of a diet high in fat and sugar can lead to the development of obesity, type 2 diabetes mellitus (T2DM), cardiovascular disease and cognitive decline. In the human gut, the trillions of harmless microorganisms harboured in the host's gastrointestinal tract are called the 'gut microbiota'. Consumption of a diet high in fat and sugar changes the healthy microbiota composition which leads to an imbalanced microbial population in the gut, a phenomenon known as "gut dysbiosis". It has been shown that certain types of gut microbiota are linked to the pathogenesis of obesity. In addition, long-term consumption of a high fat diet is associated with cognitive decline. It has recently been proposed that the gut microbiota is part of a mechanistic link between the consumption of a high fat diet and the impaired cognition of an individual, termed "microbiota gut-brain axis". In this complex relationship between the gut, the brain and the gut microbiota, there are several types of gut microbiota and host mechanisms involved. Most of these mechanisms are still poorly understood. Therefore, this review comprehensively summarizes the current evidence from mainly in vivo (rodent and human) studies of the relationship between diet, gut microbiota and cognition. The possible mechanisms that the diet and the gut microbiota have on cognition are also presented and discussed. PMID- 27709428 TI - Intoxication and biochemical responses of freshwater snail Bellamya aeruginosa to ethylbenzene. AB - No acute toxic data of ethylbenzene on gastropod is available in literature. In the present study, the acute toxicity of ethylbenzene was assessed on a freshwater snail Bellamya aeruginosa, which was exposed to ethylbenzene concentration from 1 to 100 mg/L for 96 h. No mortality occurred, but a manifestation of intoxication (distress syndrome) was observed in part of exposed snails, and meanwhile, another part was moved normally. The distress syndrome showed clear dose- and time-dependent effects, and the 96-h EC50 value for distress syndrome was 13.3 mg/L in snail. The biochemical responses induced by ethylbenzene to the snail, including acetylcholinesterase (AChE) in the whole body and superoxide dismutase (SOD), catalase (CAT), glutathione S-transferases (GST), and reduced glutathione (GSH) in the hepatopancreas, were evaluated both for distressed snail and moved snail. The AChE activity of distressed snail was all inhibited more than 45 %, and the inhibition of AChE activity in the moved snail was all less than 30 % and more than 20 %, demonstrating that ethylbenzene exerted nervous toxicity to both distressed snail and moved snail. Meanwhile, the difference for AChE activity between the two different response snails was significant. Among the antioxidant biomarkers (SOD, CAT, GST, and GSH), only GST displayed significant difference between the distressed snail and moved snail. However, the activities of enzymes (SOD, CAT, and GST) in the moved snail were greater than those in the distressed snail, no matter significantly or insignificantly, which indicated that the ability of antioxidant defense in the distressed snail was weaker than that in the moved snail. The findings here reported manifest that ethylbenzene exerted nervous toxicity to snail, and the snail with intoxication response (distress syndrome) presented larger inhibition on AChE activity and weaker antioxidant ability in comparison with the moved snail. PMID- 27709430 TI - Bioaccumulation of natural radionuclides in molluscs from the Ebro Delta area. AB - 210Po, 210Pb, 234U, 238U, 232Th and 230Th were analysed in the edible part of four different species of bivalves typically produced and consumed in the Ebro Delta area. The results show that the main contributor to the radioactive content in these species was 210Po, with values ranging between 263.1 +/- 26.6 and 813.0 +/- 72.9 Bq/kg (d.w.), which are higher than the usual reported activity levels in other geographical areas. This can probably be attributed to the activities of a phosphate industrial plant located upstream on the Ebro River, which may lead to enhanced levels of naturally occurring radioactive isotopes in the aquatic ecosystem. To determine the possible impact on health, the committed effective doses through the consumption of the different species were evaluated and the cumulative total annual effective dose for their consumption was estimated to 187.6 MUSv/year, which is in the range of 200-1000 MUSv/year given by UNSCEAR.

AB - This paper reports the results of vermicomposting of water lettuce biomass (WL) spiked with cow dung at ratios of 20, 40, 60, and 80 % employing Eisenia fetida. A total of four treatments were established and changes in chemical properties of mixtures were observed. Vermicomposting caused a decrease in pH, TOC, volatile solids, and C/N ratio by 1.01-1.08-fold, 0.85-0.92-fold, 0.94-0.96-fold, 0.56 0.70-fold, respectively, but increase in EC, totN, totP, totK, totCa, totZn, totFe, and totCu, by 1.19-1.42-fold, 1.33-1.68-fold, 1.38-1.69-fold, 1.13-1.24 fold, 1.04-1.11-fold, 1.16-1.37-fold, 1.05-1.113-fold, 1.10-1.27-fold, respectively. Overall, the treatment with 60-80 % of WL showed the maximum decomposition and mineralization rates. The earthworm showed the growth and reproduction rate in considerable ranges in all treatment setups but setups with 60-80 % WL proportion exhibited the optimum results. Results reveal that biomass of water lettuce can be utilized effectively for production of valuable manure through vermicomposting system.

AB - Endosulfan, an organochlorine pesticide, was found in human blood, and its possible cardiovascular toxicity has been suggested. However, the mechanism about endothelial cell injuries induced by endosulfan has remained unknown. In the present study, human umbilical vein endothelial cells (HUVECs) were chosen to explore the toxicity mechanism and were treated with 0, 1, 6, and 12 MUg/mL-1 endosulfan for 24 h, respectively. The results showed that exposure to endosulfan could inhibit the cell viability, increase the release of lactate dehydrogenase (LDH), damage the ultrastructure, and lead to apoptosis and necroptosis in HUVECs. Furthermore, endosulfan upregulated the expressions of receptor interacting protein kinase 1 (RIPK1), receptor-interacting protein kinase 3 (RIPK3), mixed lineage kinase domain-like (MLKL), caspase 8, and caspase 3, which means the activation of RIPK1 pathways. In addition, endosulfan promoted the increases of ROS, IL-1alpha, and IL-33 levels while antioxidant N-acetyl-L cysteine (NAC) effectively attenuated the cytotoxicity from endosulfan. Taken together, these results have demonstrated that endosulfan induces the apoptosis and necroptosis of HUVECs, where the RIPK pathway plays a pro-necroptotic role and NAC plays an anti-necroptotic role. Our results may contribute to understanding cellular mechanisms for endosulfan-induced cardiovascular toxicity. PMID- 27709432 TI - Effects of CeO2, CuO, and ZnO nanoparticles on physiological features of Microcystis aeruginosa and the production and composition of extracellular polymeric substances. AB - Extracellular polymeric substances (EPS) are key components of the cyanobacterium Microcystis aeruginosa and play an important role in cyanobacteria blooms formation. Here, we analyzed the effects of 48-h exposure to nanosized CeO2 (n CeO2), CuO (n-CuO), and ZnO (n-ZnO) on the production and composition of EPS of M. aeruginosa. Toxicity experiments revealed that soluble nanoparticles (NPs) (n ZnO, n-CuO) demonstrated higher toxicity to cells and caused membrane damage. The production of LB-EPS increased by 34.48, 20.09, and 46.33 %, and TB-EPS increased by -5.78, 22.3, and -2.67 % in the presence of n-CeO2, n-CuO, and n-ZnO NPs, respectively, and polysaccharides are the main incremental portion compared with protein and humic acids. Three-dimensional excitation-emission fluorescence spectra revealed the enhancement of fulvic-humic-like and disappearance of tyrosine aromatic substances in TB-EPS compared with the slight changes observed in LB-EPS. Fourier-transform infrared spectroscopy illustrated the susceptibility of -NH2 and double-bonded carbon and oxygen in amides to three types of NPs. These results improve our understanding of the potential influence of NPs on the aggregation behaviors of cyanobacteria and formation process of cyanobacteria blooms. Graphical abstract ?.

AB - A survey of maize fields was conducted in northeast Italy from 1986 to 2014, resulting in a dataset of 1296 records including information on wireworm damage to maize, plant-attacking species, agronomic characteristics, landscape and climate. Three wireworm species, Agriotes brevis Candeze, A. sordidus Illiger and A. ustulatus Schaller, were identified as the dominant pest species in maize fields. Over the 29-year period surveyed, no yield reduction was observed when wireworm plant damage was below 15 % of the stand. A preliminary univariate analysis of risk assessment was applied to identify the main factors influencing the occurrence of damage. A multifactorial model was then applied by using the significant factors identified. This model allowed the research to highlight the strongest factors and to analyse how the main factors together influenced damage risk. The strongest factors were: A. brevis as prevalent damaging species, soil organic matter content >5 %, rotation including meadows and/or double crops, A. sordidus as prevalent damaging species, and surrounding landscape mainly meadows, uncultivated grass and double crops. The multifactorial model also showed how the simultaneous occurrence of two or more of the aforementioned risk factors can conspicuously increase the risk of wireworm damage to maize crops, while the probability of damage to a field with no-risk factors is always low (<1 %). These results make it possible to draw risk maps to identify low-risk and high-risk areas, a first step in implementing bespoke IPM procedures in an attempt to reduce the impact of soil insecticides significantly. PMID- 27709434 TI - Complete adherence to evidence-based quality-of-care indicators for Staphylococcus aureus bacteremia resulted in better prognosis. AB - PURPOSE: Staphylococcus aureus bacteremia (SAB) is a serious clinical condition associated with high morbidity and mortality. Recent studies have revealed that adherence to evidence-based quality-of-care indicators (QCIs) for the management of SAB could result in reduced mortality. We aimed to determine whether compliance with QCIs was associated with mortality and whether compliance with QCIs predicted the mortality of patients with SAB. METHODS: In a university hospital in Kyoto, Japan, SAB patients, who survived at least 14 days after positive blood cultures were analyzed from 2006 to 2014 to assess their compliance with QCIs and the trend in mortality. In addition, the predicted mortality, which was stratified by the number of fulfilled QCIs (QCI points), was calculated. In this study, the following five main QCI points were evaluated: (1) follow-up blood cultures; (2) early source control when applicable; (3) echocardiography; (4) the early use of appropriate antibiotics, and (5) the appropriate duration of therapy. RESULTS: We identified 477 eligible SAB cases, of which 199 were MRSA cases (41.7 %). The proportion of SAB cases in which the physicians adhered to at least four QCIs increased gradually from 47.5 % in 2006 to 79.3 % in 2014 (P = 0.001); whereas, the 30-day mortality decreased from 10.0 to 3.4 % after treatment completion. CONCLUSIONS: With an increase in the proportion of SAB cases adhering to QCIs, better prognoses were observed for patients with SAB. The QCI points reflected the 30-day mortality. PMID- 27709435 TI - Virological Quality of Irrigation Water in Leafy Green Vegetables and Berry Fruits Production Chains. AB - This study condenses data acquired during investigations of the virological quality of irrigation water used in production of fresh produce. One hundred and eight samples of irrigation water were collected from five berry fruit farms in Finland (1), the Czech Republic (1), Serbia (2), and Poland (1), and sixty-one samples were collected from three leafy green vegetable farms in Poland, Serbia, and Greece. Samples were analyzed for index viruses of human or animal fecal contamination (human and porcine adenoviruses, and bovine polyoma viruses), and human pathogenic viruses (hepatitis A virus, hepatitis E virus, and noroviruses GI/GII). Both index and pathogenic viruses were found in irrigation water samples from the leafy green vegetables production chain. The data on the presence of index viruses indicated that the highest percentage of fecal contamination was of human origin (28.1 %, 18/64), followed by that of porcine (15.4 %, 6/39) and bovine (5.1 %, 2/39) origins. Hepatitis E virus (5 %, 1/20) and noroviruses GII (14.3 %, 4/28) were also detected. Samples from berry fruit production were also positive for both index and pathogenic viruses. The highest percentage of fecal contamination was of human origin (8.3 %, 9/108), followed by that of porcine, 4.5 % (4/89) and bovine, 1.1 % (1/89) origins. Norovirus GII (3.6 %, 2/56) was also detected. These data demonstrate that irrigation water used in primary production is an important vehicle of viral contamination for fresh produce, and thus is a critical control point which should be integrated into food safety management systems for viruses. The recommendations of Codex Alimentarius, as well as regulations on the use of water of appropriate quality for irrigation purposes, should be followed. PMID- 27709436 TI - Rapid and Sensitive Detection of Lymphocystis Disease Virus Genotype VII by Loop Mediated Isothermal Amplification. AB - Lymphocystis disease virus (LCDV) infections have been described in gilthead seabream (Sparus aurata L.) and Senegalese sole (Solea senegalensis, Kaup), two of the most important marine fish species in the Mediterranean aquaculture. In this study, a rapid, specific, and sensitive detection method for LCDV genotype VII based on loop-mediated isothermal amplification (LAMP) was developed. The LAMP assay, performed using an apparatus with real-time amplification monitoring, was able to specifically detect LCDV genotype VII from clinically positive samples in less than 12 min. In addition, the assay allowed the detection of LCDV in all asymptomatic carrier fish analysed, identified by qPCR, showing an analytical sensitivity of ten copies of viral DNA per reaction. The LCDV LAMP assay has proven to be a promising diagnostic method that can be used easily in fish farms to detect the presence and spread of this iridovirus. PMID- 27709438 TI - 3D structure prediction of histone acetyltransferase proteins of the MYST family and their interactome in Arabidopsis thaliana. AB - Histone lysine acetylation is a reversible post-translational modification that does not involve changes in DNA sequences. Enzymes play an important role in developmental processes and their deregulation has been linked to the progression of diverse disorders. The HAT enzyme family fulfills an important role in various developmental processes mediated by the state of chromatin, and have been attributed to its deregulation. To understand acetylation mechanisms and their role in cell signaling, transcriptional regulation, and apoptosis, it is crucial to identify and analyze acetylation sites. Bioinformatics methods can be used to generate relatively precise predictions. Here we applied classical bioinformatics methods-sequence alignment, homology modeling, and docking-to compare approved and predicted lysine acetylation processes in different organisms. HAM1 and HAM2 are analogs of KAT8 and KAT7 (MYST1 and MYST2), members of the MYST histone acetyltransferase family, and our results show that HAM1 and HAM2 have much in common with other representatives of MYST families from various organisms. One function of acetyl-CoA binding was predicted with a high level of probability by computational methods. Based on our data, we conclude that, despite huge genetic distances and some structural differences between animal and plant species, a closer look at acetylation mechanism shows that they have much in common. PMID- 27709439 TI - Theoretical studies on the hydrogen-bonding interactions between luteolin and water: a DFT approach. AB - Flavonoids are among the most important bioactive compounds responsible for the medical properties of honey and propolis. Water is the solvent most commonly used to extract flavonoids from honey and propolis. Hydrogen-bonding interactions are of great importance in the extraction process. In this work, hydrogen-bonding interactions between a representative flavonoid, luteolin, and water were investigated by density functional theory (DFT) from a theoretical viewpoint. The following conclusions were drawn: first, the molecular structure of luteolin is non-planar. Second, nine optimized geometries for the luteolin-H2O complex were obtained. With the exception of the aromatic hydrogen atoms in the phenyl substituent, the other hydrogen and oxygen atoms formed hydrogen-bonds with H2O. Third, luteolin-H2O complexation is accompanied by charge rearrangement. The electron density and the second-order perturbation stabilization energy [E(2)] in the related anti-bonding orbital of the hydrogen-bond donors were increased, causing elongation and a red-shift of the X-H bond in X-H...Y. The stronger interaction makes the electron density and the E(2) increase more in the more stable geometries. The sum of the electron density is transferred from hydrogen bond acceptors to donors. Fourth, the hydrogen-bonds in the luteolin-H2O complex are weak and basically electrostatic in nature. In addition, O-H...O hydrogen bonds are stronger than C-H...O hydrogen-bonds in the luteolin-H2O complex. PMID- 27709437 TI - Insomnia in probable migraine: a population-based study. AB - BACKGROUND: Insomnia is a common complaint among individuals with migraine. The close association between insomnia and migraine has been reported in clinic-based and population-based studies. Probable migraine (PM) is a migrainous headache which fulfills all but one criterion in the migraine diagnostic criteria. However, an association between insomnia and PM has rarely been reported. This study is to investigate the association between insomnia and PM in comparison with migraine using data from the Korean Headache-Sleep Study. METHODS: The Korean Headache-Sleep Study is a nation-wide cross-sectional survey for all Korean adults aged 19-69 years. The survey was performed via face-to-face interview using a questionnaire on sleep and headache. If an individual's Insomnia Severity Index score was >=15.5, she/he was diagnosed as having insomnia. RESULTS: Of 2695 participants, the prevalence of migraine, PM and insomnia was 5.3, 14.1 and 3.6 %, respectively. The prevalence of insomnia among subjects with PM was not significantly different compared to those with migraine (8.2 % vs. 9.1 %, p = 0.860). However, insomnia prevalence in subjects with PM was significantly higher than in non-headache controls (8.2 % vs. 1.8 %, p < 0.001). Insomnia Severity Index score was significantly higher in subjects with migraine compared to those with PM (6.8 +/- 5.8 vs. 5.5 +/- 5.8, p = 0.012). Headache frequency and Headache Impact Test-6 score were significantly higher in subjects with migraine and PM with insomnia compared to those without insomnia. Multivariable linear analyses showed that anxiety, depression, headache frequency and headache intensity were independent variables for contributing the ISI score among subjects with PM. CONCLUSIONS: The prevalence of insomnia among subjects with PM was not significantly different compared to those with migraine. Anxiety, depression, headache frequency and headache intensity were related with ISI score in subjects with PM.

AB - Using molecular dynamics simulations, we investigated the thermal stability and real-time denaturation of a model mini-protein in four solvents: (1) water, (2) 1 ethyl-3-methylimidazolium alaninate [EMIM][ALA] (5 mol% in water), (3) methioninate [EMIM][MET] (5 mol% in water), and (4) tryptophanate [EMIM][TRP] (5 mol% in water). Upon analyzing the radius of gyration, the solvent-accessible surface area, root-mean-squared deviations, and inter- and intramolecular hydrogen bonds, we found that the mini-protein remains stable at 30-40 K higher temperatures in aqueous amino acid based ionic liquids (AAILs) than in water. This thermal stability was correlated with the thermodynamics and shear viscosity of the AAIL-containing mixtures. These results suggest that AAILs are generally favorable for protein conservation.

PMID- 27709441 TI - Correlation Between Intraocular Pressure and Central Corneal Thickness in Persian Children. AB - INTRODUCTION: This study aimed to determine intraocular pressure (IOP) and central corneal thickness (CCT) measurements in healthy Persian children to find clinical reference values in this ethnicity. Additionally, we examined the possible relationship between these measurements. METHODS: This cross-sectional study included 262 eyes of 131 Persian primary school children between 6 and 13 years of age. All eyes were healthy and had no anterior or posterior segment abnormalities, corneal disease, or evidence of glaucoma. Specular microscopy was used to measure CCT and both noncontact tonometry (NCT) and Goldmann applanation tonometer (GAT) were used to measure IOP. Correlations between IOP measurements were also examined. RESULTS: Mean CCT was 513.47 +/- 34.51 MUm in the right eye (OD) and 513.93 +/- 33.88 MUm in the left eye (OS). The CCT was not significantly different between older (10-13 years) and younger (6-9 years) patients. Mean IOP measured with GAT was 13.86 +/- 2.13 mmHg OD and 13.72 +/- 2.04 mmHg OS and mean IOP measured with NCT was 15.26 +/- 2.38 mmHg OD and 15.11 +/- 2.18 mmHg OS. The IOP and CCT measured with GAT were weakly correlated (OD: r = 0.141, P = 0.114; OS: r = 0.236, P = 0.007). However, IOP and CCT measured with NCT (OD: r = 0.487, P = 0.000; OS: r = 0.456, P = 0.000) were moderately correlated. Our outcomes demonstrated that for 100 MUm increase in CCT, IOP measured with GAT and NCT increased by 0.8 and 3.3 mmHg, respectively, in OD and by 1.4 and 2.9 mmHg in OS. Based on intraclass correlation coefficients, IOP measurements made with GAT and NCT were in fair agreement in OD and in good agreement in OS. CONCLUSION: The IOP and CCT in healthy Persian school children (6-13 years old) were positively correlated. Our findings revealed that corneal thickness is thinner in Persian children than in most other racial groups. FUNDING: This study has been funded by deputy dean in research of School of Medicine and deputy vice chancellor of Shiraz University of Medical Sciences, Shiraz, Iran. PMID- 27709442 TI - Memory strategy use in older adults with subjective memory complaints. AB - BACKGROUND: Subjective memory complaints (SMC) are common among older adults, but it is unclear to what extent adults with SMC spontaneously use memory strategies to compensate for their memory problems. As SMC may be a risk factor for memory decline later, it is important to extend our knowledge about spontaneous compensatory mechanisms in older adults with SMC. METHOD: Self-reported strategy use and observed strategy use were assessed in 38 adults with and 38 without SMC. RESULTS: Adults with SMC used more strategies in daily life than those without. In the SMC group, memory complaints were positively correlated with strategy use. Only in adults without SMC, a significant correlation was found between observed strategy use and task performance. CONCLUSION: Strategy use in older adults with SMC may be compensatory in nature, but did not increase their objective memory performance. Therefore, older adults with SMC might benefit from interventions aimed at optimizing strategy use. PMID- 27709443 TI - Safety and efficacy of etanercept and adalimumab in children aged 2 to 4 years with juvenile idiopathic arthritis. AB - The TNF inhibitors etanercept (ETA) and adalimumab (ADA) are approved for treating patients older than 2 years with polyarticular juvenile idiopathic arthritis (JIA). Because long-term experience of treating children younger than 4 years is limited, we evaluated the efficacy and safety of ETA or ADA in patients aged 2-4 years. This prospective, long-term, observational registry study documented baseline demographics, clinical characteristics, disease activity parameters, and safety of patients treated with ETA or ADA. Efficacy was determined using the JADAS-10, the JADAS criteria for minimal disease activity (MDA) and remission, and the PedACR response criteria after 3, 6, 12, 18, and 24 months. Between January 2001 and March 2015, 85 patients with polyarticular JIA aged 2-4 years started anti-TNF-alpha treatment. Seventy-four (54 girls) patients were treated with ETA and 11 (7 girls) with ADA. After 6/12/24 months of treatment, JADAS-MDA was reached by 55/58/58 % of ETA patients and 50/71/66 % of ADA patients. Furthermore, JADAS-Remission was achieved by 35/44/50 % of ETA patients and 16/28/66 % of ADA patients. PedACR 50/70/90 response was achieved by 64/54/41 % of ETA patients and 56/33/22 % of ADA patients at the last treatment observation. Discontinuation because of remission or inefficacy was recorded in 24 (29 %) and 28 (33 %) patients, respectively. Seventy-nine adverse events and four serious adverse events were reported. Administration of ETA and ADA in JIA patients younger than 4 years was efficacious, well tolerated, and safe. Patients younger than 4 years may show marked improvement following anti-TNF-alpha therapy. PMID- 27709445 TI - Childhood polyarteritis nodosa: diagnosis with non-invasive imaging techniques. AB - There is limited number of publications about the use of non-invasive imaging modalities in the diagnosis of childhood polyarteritis nodosa (cPAN). The aim of this study was to present the clinical and imaging findings of the patients with cPAN who were diagnosed with non-invasive imaging techniques. Files of patients who had been diagnosed as cPAN in our department from 2005 to 2015 were reviewed, retrospectively. Demographic, clinical, laboratory, and imaging findings of the patients were evaluated. Nine patients (8M, 1F; age at disease onset: 12.5 years (7-16)) had been diagnosed as cPAN in our clinic with non-invasive imaging techniques within the last 10 years. Abdominal pain, fever, fatigue, and myalgia were the most frequent complaints. Doppler ultrasonography (US) was used in the diagnosis of seven patients and computed tomography (CT) angiography was done in four patients. Duration between admission to our center and diagnosis was median of 5 days (8 h-10 days), including four patients who were diagnosed within 24 h of admission. Approximately 80 % of our patients with cPAN had MEFV gene mutations and 90 % had elevated anti-streptolysin O levels. All of them had the involvement of the gastrointestinal tract. Hepatic and cystic arterial involvements were detected in seven and six patients, respectively. This report included the largest cPAN series that were diagnosed with non-invasive imaging modalities. We suggest that non-invasive modalities, especially Doppler US, should be considered in first line approach in the diagnosis of these patients, particularly in children. PMID- 27709444 TI - The usage of biological DMARDs and clinical remission of rheumatoid arthritis in China: a real-world large scale study. AB - The aims of this study are to characterize the biological disease-modifying antirheumatic drug (bDMARD) usage patterns in real-life and examine the remission rate of rheumatoid arthritis (RA) patients receiving bDMARDs in routine clinical practice in China. Consenting RA patients (>=18 years) from 15 teaching hospitals and receiving marketed bDMARDs were included. In total, 802 patients (81.3 % women, 49.0 +/- 13.9 years) were included; 89.5 % were receiving a combination of bDMARDs and conventional synthetic DMARDs (csDMARDS), whereas 10.5 % were receiving bDMARD monotherapy. Etanercept (including Enbrel(r) and local brand Yi Sai Pu(r) and Qiangke(r)), tocilizumab, adalimumab, and infliximab were used by 66.6 %, 17.0 %, 7.5 %, and 6.6 % patients, respectively. Etanercept was used at a mean weekly dose of 38.2 +/- 15.6 mg for 25.5 +/- 47.0 weeks and tocilizumab at 94.5 +/- 21.9 mg for 4.7 +/- 7.5 weeks. Overall rate of remission was 12.6 %, 5.4 % , and 3.5 % based on DAS28, CDAI, and SDAI scores, respectively. Compared with patients receiving bDMARDs for <3 months, those receiving bDMARDs for >=3 months exhibited significantly lower DAS28 scores (p < 0.0001), and a significantly higher proportion of patients who received bDMARDs for >=12 months achieved the treatment goal (remission or low disease activity, 62.5 % vs. 18.3 %, p < 0.0001). Patients receiving combination therapy with csDMARDs exhibited lower DAS28 scores than patients receiving bDMARD monotherapy (4.3 vs. 4.8, p = 0.011). This large-scale real-world study showed that bDMARD usage patterns in routine clinical practice in China were in accordance with international guidelines for RA management despite the short treatment duration. Longer duration of bDMARD usage and combination therapy showed a favored outcome of RA. PMID- 27709446 TI - Triple-loop reentrant atrial tachycardia originated after pulmonary vein isolation. PMID- 27709449 TI - Human chorionic gonadotropin (hCG) concentrations during the late first trimester are associated with fetal growth in a fetal sex-specific manner. AB - Human chorionic gonadotropin (hCG) is a pregnancy-specific hormone that regulates placental development. hCG concentrations vary widely throughout gestation and differ based on fetal sex. Abnormal hCG concentrations are associated with adverse pregnancy outcomes including fetal growth restriction. We studied the association of hCG concentrations with fetal growth and birth weight. In addition, we investigated effect modification by gestational age of hCG measurement and fetal sex. Total serum hCG (median 14.4 weeks, 95 % range 10.1 26.2), estimated fetal weight (measured by ultrasound during 18-25th weeks and >25th weeks) and birth weight were measured in 7987 mother-child pairs from the Generation R cohort and used to establish fetal growth. Small for gestational age (SGA) was defined as a standardized birth weight lower than the 10th percentile of the study population. There was a non-linear association of hCG with birth weight (P = 0.009). However, only low hCG concentrations measured during the late first trimester (11th and 12th week) were associated with birth weight and SGA. Low hCG concentrations measured in the late first trimester were also associated with decreased fetal growth (P = 0.0002). This was the case for both male and female fetuses. In contrast, high hCG concentrations during the late first trimester were associated with increased fetal growth amongst female, but not male fetuses. Low hCG in the late first trimester is associated with lower birth weight due to a decrease in fetal growth. Fetal sex differences exist in the association of hCG concentrations with fetal growth. PMID- 27709447 TI - Current views on HIV-1 latency, persistence, and cure. AB - HIV-1 infection cannot be cured as it persists in latently infected cells that are targeted neither by the immune system nor by available therapeutic approaches. Consequently, a lifelong therapy suppressing only the actively replicating virus is necessary. The latent reservoir has been defined and characterized in various experimental models and in human patients, allowing research and development of approaches targeting individual steps critical for HIV-1 latency establishment, maintenance, and reactivation. However, additional mechanisms and processes driving the remaining low-level HIV-1 replication in the presence of the suppressive therapy still remain to be identified and targeted. Current approaches toward HIV-1 cure involve namely attempts to reactivate and purge HIV latently infected cells (so-called "shock and kill" strategy), as well as approaches involving gene therapy and/or gene editing and stem cell transplantation aiming at generation of cells resistant to HIV-1. This review summarizes current views and concepts underlying different approaches aiming at functional or sterilizing cure of HIV-1 infection. PMID- 27709451 TI - Successful early romiplostim use in a case of severe immune thrombocytopenia with critical carotid arterial injury. AB - Thrombopoietin receptor (TPO-R) agonists have been shown to be effective in refractory chronic immune thrombocytopenia (ITP); however, their efficacy in patients under critical care is not known. We report the case of a female patient with a newly diagnosed ITP who experienced severe bleeding from an external wound. The patient was administered the standard treatments for ITP, which are high-dose intravenous immunoglobulin (IVIg) and corticosteroids. However, following failure of these treatments, we administered romiplostim on day 6 after the onset of ITP. On day 6 after the initiation of romiplostim, there was improvement in platelet count and bleeding tendency. We were subsequently able to perform a splenectomy successfully. The efficacy of TPO-R agonists in ITP has been reported in several situations, including before surgery in an ITP patient; however, the use of TPO-R for arterial bleeding with shock has not been reported. To our knowledge, the present article is a rare case report of the use of a TPO-R agonist in a patient with critical artery injury. Our data suggest that the early use of romiplostim is effective in emergency cases of newly diagnosed ITP with life-threatening bleeding, which is refractory to standard treatment. PMID- 27709448 TI - A pooled analysis of the association of isolated low levels of high-density lipoprotein cholesterol with cardiovascular mortality in Japan. AB - Low levels of serum high-density lipoprotein cholesterol (HDL-C) have been shown to be associated with increased risk of coronary heart disease (CHD). However, because this is usually observed in the context of other lipid abnormalities, it is not known whether isolated low serum HDL-C levels are an independent risk factor for CHD. We performed a large pooled analysis in Japan using data from nine cohorts with 41,206 participants aged 40-89 years who were free of cardiovascular disease at baseline. We divided participants into three groups: isolated low HDL-C, non-isolated low HDL-C, and normal HDL-C. Cohort-stratified Cox proportional hazards models were used to estimate multivariate-adjusted hazard ratios (HRs) for death due to CHD, ischemic stroke, and intracranial cerebral hemorrhage; during a 12.9-year follow-up, we observed 355, 286, and 138 deaths, respectively, in these groups. Non-isolated low HDL-C was significantly associated with increased risk of CHD compared with normal HDL-C (HR 1.37, 95 % confidence interval (CI) 1.04-1.80); however, isolated low HDL-C was not. Although isolated low HDL-C was significantly associated with decreased risk of CHD (HR 0.51, 95 % CI 0.29-0.89) in women, it was significantly associated with increased risk of intracranial cerebral hemorrhage in all participants (HR 1.62, 95 % CI 1.04-2.53) and in men (HR 2.00, 95 % CI 1.04-3.83). In conclusion, isolated low HDL-C levels are not associated with increased risk of CHD in Japan. CHD risk may, therefore, be more strongly affected by serum total cholesterol levels in this population.

AB - The study was aimed to explore the efficacy and safety of allo-HSCT with high dose cyclophosphamide-induced immune tolerance for SAA. In the present study, 20 cases (12 male, 8 female; average age = 17.8 years) received reduced-intensity conditioning allo-HSCT from August 2012 to August 2014 in the Beijing Military Region General Hospital. All were HLA mismatched and received CSA; 11 received ATG-intensive immune therapy. Donors underwent mobilization with cell colony stimulating factor. The modified preconditioning regimen included reduced strength fludarabine combined with Busulfex and cytarabine, cyclophosphamide. Cyclophosphamide (50 mg/kg/d) induced immune tolerance 3 days after transplantation and was combined with immunosuppressive agents, including CSA, MTX, and FK506, for GVHD prophylaxis and the management of observed toxicity, GVHD and DFS. Hematopoietic reconstitution was achieved in 17 cases and engraftment after a second transplantation in an additional three cases. The average times to engraftment were 17.4 and 21.3 days, respectively, with neutrophils >=0.5 * 109/L and platelets >=20 * 109/L. Engraftment was confirmed by the evidence of 100 % donor hematopoiesis; T lymphocyte subset counts also increased significantly after transplantation. During follow-up monitoring to April 2015 (median duration = 17.7 months), three patients died of complications, while the other 17 showed disease-free survival (DFS rate = 85 %; longest DFS period = 32 months). Reduced-intensity allo-HSCT with high-dose cyclophosphamide induced immune tolerance treatment is effective for SAA and can be the key technology extensively used in clinic, but its efficacy needs to be confirmed further with prospective randomized study with increased sample size. PMID- 27709452 TI - Statistical Approaches to Assess Biosimilarity from Analytical Data. AB - Protein therapeutics have unique critical quality attributes (CQAs) that define their purity, potency, and safety. The analytical methods used to assess CQAs must be able to distinguish clinically meaningful differences in comparator products, and the most important CQAs should be evaluated with the most statistical rigor. High-risk CQA measurements assess the most important attributes that directly impact the clinical mechanism of action or have known implications for safety, while the moderate- to low-risk characteristics may have a lower direct impact and thereby may have a broader range to establish similarity. Statistical equivalence testing is applied for high-risk CQA measurements to establish the degree of similarity (e.g., highly similar fingerprint, highly similar, or similar) of selected attributes. Notably, some high-risk CQAs (e.g., primary sequence or disulfide bonding) are qualitative (e.g., the same as the originator or not the same) and therefore not amenable to equivalence testing. For biosimilars, an important step is the acquisition of a sufficient number of unique originator drug product lots to measure the variability in the originator drug manufacturing process and provide sufficient statistical power for the analytical data comparisons. Together, these analytical evaluations, along with PK/PD and safety data (immunogenicity), provide the data necessary to determine if the totality of the evidence warrants a designation of biosimilarity and subsequent licensure for marketing in the USA. In this paper, a case study approach is used to provide examples of analytical similarity exercises and the appropriateness of statistical approaches for the example data.

AB - Death with dignity is a significant issue in modern bioethics. In modern healthcare, the wide use of new technologies at the end of life has caused heated debate on how to protect human dignity. The key point of contention lies in the different understandings of human dignity and the dignity of death. Human dignity has never been a clear concept in Western ethical explorations, and the dignity of death has given rise to more confusions. Although there is no such term as "dignity" in Confucian ethics, there are discussions of a number of ideas related to human dignity and the dignity of death. Therefore, Confucian bioethics can offer a new perspective for understanding the theoretical difficulties associated with the dignity of death and new methods for solving them. In this article, we attempt to reconstruct Confucian views on human dignity and the dignity of death and, based on those views, to analyze the following issues: the relationship between the dignity of death and biological life, the relationship between the dignity of death and suffering, the relationship between the dignity of death and the autonomy of human beings, and the relationship between the dignity of death and social justice. This article will also compare the Confucian views on these issues with the views of Western philosophers. Confucian ethics can offer distinct answers to the above issues and help resolve some confusions concerning concepts and theories in Western research on the dignity of death.

AB - Writing is central both to the medical diagnostic codification of disability and to disabled people's efforts to interrupt, complicate, or disrupt dominant medical narratives. This Symposium, like the George Washington University conference from which it takes its name, creates space for diverse modes and genres of claiming authority regarding diagnosis and its cultural and material effects. "Queer" and "crip" interrogations of diagnosis illuminate its status as a cultural phenomenon, embracing culturally disavowed embodiments and embodied experiences as tools for diagnosing inegalitarian social relations and opportunities for cultural interventions. This Symposium traces the workings of diagnostic normativity manifested in experiences such as "disruptive deafness," unstable bodily materialities, pathologized grief and other forms of affective distress, and "surgical assemblages." It presents a diverse array of compositions, articulated on each writer's own terms, addressing a range of embodied experiences through multiple genres and voices, ranging from conversation transcript to scholarly essay, poetry, graphic memoir, and personal essay. Here, laypersons interrupt monologic medical diagnosis, claiming space to compose themselves. Together, the authors trace instances of corporeal "correction" back to the noxious agents, both environmental and political, that consistently breach the boundaries of corporeality. PMID- 27709456 TI - Leveraging Partnerships: Families, Schools, and Providers Working Together to Improve Asthma Management. AB - Asthma is one of the most common illnesses of school-aged children and can lead to both health and educational disparities. Children from low socioeconomic backgrounds and racial/ethnic minorities suffer the greatest impact. They often lack the asthma self-management skills to successfully monitor, navigate, and negotiate appropriate asthma care. School settings are a strategic point of contact for this additional support. School nurses can monitor for signs of asthma worsening, manage symptoms, provide care coordination, and reinforce self management skills. Likewise, school-based asthma programs have the potential to reduce health and educational disparities, but it is the strong linkage to the asthma care provider that is critical to successful school-based asthma management. Healthcare providers are encouraged to establish partnerships with families through patient-centered care and schools through clear communication and care coordination to ensure asthma is well controlled so the child is in school and ready to learn.

PMID- 27709459 TI - Novel carboxymethyl chitosan-graphene oxide hybrid particles for drug delivery. AB - We describe an electrostatic droplet generation method to prepare a novel carboxymethyl chitosan-graphene oxide hybrid particles for delivery purpose. Under an adjustable electrostatic field, graphene oxide and carboxymethyl chitosan mixed solution was sprayed as uniform micro-droplets, which were solidified as particles in CaCl2 solution. Such hybrid particles are wished to have excellent stability in saline solution, and better delivery properties than pristine carboxymethyl chitosan particles. The effects of micro-droplets generation conditions on particles formation were systematically investigated. At conditions of 40 mg/ml of carboxymethyl chitosan, 2 mg/ml of graphene oxide, 3 ml/h of feed speed, electrostatic field parameters was 9 kV and 20 cm, uniformly sized carboxymethyl chitosan-graphene oxide particles in the diameter range of 250-300 MUm was successfully prepared. In NaCl saline, these particles could maintain stable for at least a week, while pristine carboxymethyl chitosan particles quickly collapsed within an hour. The results of loading experiments showed that carboxymethyl chitosan-graphene oxide particles could effectively adsorb gatifloxacin, ofloxacin, bovine serum albumin, lysozyme, doxorubicin hydrochloride. And gatifloxacin was chosen as a model drug to study the exact effect of graphene oxide content on the loading and release properties. In 40:2 group, the highest loading capacity of 0.45 +/- 0.19 mg/mg was achieved, and also a good sustained release was available. Above all, we believed that carboxymethyl chitosan-graphene oxide particles as a versatile carrier, has great potential in Medicine and Pharmacy. PMID- 27709460 TI - A Prospective, Randomized, Open-Label Study to Evaluate Two Management Strategies for Gastrointestinal Symptoms in Patients Newly on Treatment with Dabigatran. AB - INTRODUCTION: In the pivotal RE-LY trial, dabigatran etexilate (DE) at the dose of 150-mg twice daily (BID), significantly reduced total stroke and ischemic stroke compared with warfarin in patients with non-valvular atrial fibrillation (NVAF), while the 110-mg BID dose had efficacy equivalent to warfarin, and major bleeds were significantly reduced. Both DE regimens were generally well tolerated; however, approximately 4% of the patients discontinued treatment with DE due to gastrointestinal (GI) discomfort. METHODS: Clinical trial NCT01493557 was a multicenter, randomized, active control, open-label study to assess the efficacy of two simple GI symptom (GIS) management strategies in DE-treated patients who developed GIS: (1) concurrent treatment with the proton pump inhibitor pantoprazole (DE-P), or (2) ingestion of DE after a meal (DE-M). Patients were initially randomized to either GIS management strategy. If the first did not resolve their GIS, patients had the option to "add on" the alternative strategy. RESULTS: A total of 1067 patients with NVAF received DE therapy BID for 3 months (United States, 150-mg or 75-mg; Canada, 150-mg or 110 mg). Of these, 117 (11%) patients reported GIS and were randomized to one of two GIS management strategies. At 4 weeks, a significantly higher rate of complete or partial effectiveness was observed in patients on DE-P than in those receiving DE M, [50/58 (86.2%) versus 40/59 (67.8%), respectively; p = 0.0273]. Patients with ongoing GIS were asked to "add on" the alternate strategy for an additional 4 weeks. Overall, 92/117 (78.6%) of randomized patients experienced complete or partial effectiveness using either the initial strategy or a combination of the two strategies: DE-P, 47 (81.0%); and DE-M, 45 (76.3%, no significant difference) (by initial strategy). CONCLUSION: The majority of patients enrolled either did not experience GIS at all, or their GIS resolved using either one individually, or a combination of the two strategies described.

AB - Equine cerebellar abiotrophy (CA) is a hereditary neurodegenerative disease that affects the Purkinje neurons of the cerebellum and causes ataxia in Arabian foals. Signs of CA are typically first recognized either at birth to any time up to 6 months of age. CA is inherited as an autosomal recessive trait and is associated with a single nucleotide polymorphism (SNP) on equine chromosome 2 (13074277G>A), located in the fourth exon of TOE1 and in proximity to MUTYH on the antisense strand. We hypothesize that unraveling the functional consequences of the CA SNP using RNA-seq will elucidate the molecular pathways underlying the CA phenotype. RNA-seq (100 bp PE strand-specific) was performed in cerebellar tissue from four CA-affected and five age-matched unaffected horses. Three pipelines for differential gene expression (DE) analysis were used (Tophat2/Cuffdiff2, Kallisto/EdgeR, and Kallisto/Sleuth) with 151 significant DE genes identified by all three pipelines in CA-affected horses. TOE1 (Log2(foldchange) = 0.92, p = 0.66) and MUTYH (Log2(foldchange) = 1.13, p = 0.66) were not differentially expressed. Among the major pathways that were differentially expressed, genes associated with calcium homeostasis and specifically expressed in Purkinje neurons, CALB1 (Log2(foldchange) = -1.7, p < 0.01) and CA8 (Log2(foldchange) = -0.97, p < 0.01), were significantly down regulated, confirming loss of Purkinje neurons. There was also a significant up regulation of markers for microglial phagocytosis, TYROBP (Log2(foldchange) = 1.99, p < 0.01) and TREM2 (Log2(foldchange) = 2.02, p < 0.01). These findings reaffirm a loss of Purkinje neurons in CA-affected horses along with a potential secondary loss of granular neurons and activation of microglial cells. PMID- 27709461 TI - Quantification of Vibrio species in oysters from the Gulf of Mexico with two procedures based on MPN and PCR. AB - Oysters can accumulate potentially pathogenic water bacteria. The objective of this study was to compare two procedures to quantify Vibrio species present in oysters to determine the most sensitive method. We analyzed oyster samples from the Gulf of Mexico, commercialized in Mexico City. The samples were inoculated in tubes with alkaline peptone water (APW), based on three tubes and four dilutions (10-1 to 10-4). From these tubes, the first quantification of Vibrio species was performed (most probable number (MPN) from tubes) and bacteria were inoculated by streaking on thiosulfate-citrate-bile salts-sucrose (TCBS) petri dishes. Colonies were isolated for a second quantification (MPN from dishes). Polymerase chain reaction (PCR) was used to determine species with specific primers: ompW for Vibrio cholerae, tlh for Vibrio parahaemolyticus, and VvhA for Vibrio vulnificus. Simultaneously, the sanitary quality of oysters was determined. The quantification of V. parahaemolyticus was significantly higher in APW tubes than in TCBS dishes. Regarding V. vulnificus counts, the differences among both approaches were not significant. In contrast, the MPNs of V. cholerae obtained from dishes were higher than from tubes. The quantification of MPNs through PCR of V. parahaemolyticus and V. vulnificus obtained from APW was sensitive and recommendable for the detection of both species. In contrast, to quantify V. cholerae, it was necessary to isolate colonies on TCBS prior PCR. Culturing in APW at 42 degrees C could be an alternative to avoid colony isolation. The MPNs of V. cholerae from dishes was associated with the bad sanitary quality of the samples. PMID- 27709462 TI - Heavy metals relationship with water and size-fractionated sediments in rivers using canonical correlation analysis (CCA) case study, rivers of south western Caspian Sea. AB - Some pollutants can qualitatively affect aquatic freshwater such as rivers, and heavy metals are one of the most important pollutants in aquatic fresh waters. Heavy metals can be found in the form of components dissolved in these waters or in compounds with suspended particles and surface sediments. It can be said that heavy metals are in equilibrium between water and sediment. In this study, the amount of heavy metals is determined in water and different sizes of sediment. To obtain the relationship between heavy metals in water and size-fractionated sediments, a canonical correlation analysis (CCA) was utilized in rivers of the southwestern Caspian Sea. In this research, a case study was carried out on 18 sampling stations in nine rivers. In the first step, the concentrations of heavy metals (Cu, Zn, Cr, Fe, Mn, Pb, Ni, and Cd) were determined in water and size fractionated sediment samples. Water sampling sites were classified by hierarchical cluster analysis (HCA) utilizing squared Euclidean distance with Ward's method. In addition, for interpreting the obtained results and the relationships between the concentration of heavy metals in the tested river water and sample sediments, canonical correlation analysis (CCA) was utilized. The rivers were grouped into two classes (those having no pollution and those having low pollution) based on the HCA results obtained for river water samples. CCA results found numerous relationships between rivers in Iran's Guilan province and their size-fractionated sediments samples. The heavy metals of sediments with 0.038 to 0.125 mm size in diameter are slightly correlated with those of water samples. PMID- 27709463 TI - Multilocation field trials for risk assessment of a combination fungicide Fluopicolide + Propamocarb in tomato. AB - Dissipation kinetics of two systemic fungicides, namely fluopicolide and propamocarb used as a combination formulation (Infinito 68.75 SC), were studied on tomato at four different locations by the All India Network Project on Pesticide Residues to recommend their pre-harvest interval (PHI) and to propose the maximum residue limits (MRL) for the two fungicides based on chronic hazard exposure assessment. The combination fungicide was sprayed thrice at the recommended dosage of 93.75 g a.i./ha fluopicolide and 937.50 g a.i./ha propamocarb as well as at double the recommended dosage of 187.50 g a.i./ha fluopicolide and 1875.0 g a.i./ha propamocarb on tomato crops and the residues were monitored periodically by GC-MS. The fungicides dissipated to below the limit of quantification (LOQ) within 10 to 15 days, with a half-life of 2-4 days for fluopicolide and 1-2 days for propamocarb. Taking into consideration the MRLs of codex and calculations made using the method of MRL fixation of the Food Safety and Standard Authority of India (FSSAI) as well as the Organization for Economic Co-operation and Development (OECD) calculator, MRL of 5 mg/kg is proposed for fluopicolide and 15 mg/kg for propamocarb, following critical exposure of the commodity considering PHI of 1 day. PMID- 27709464 TI - Heavy metals (HMs) and polycyclic aromatic hydrocarbons (PAHs) in soils of different land uses in Erbil metropolis, Kurdistan Region, Iraq. AB - Urban soil contamination is a growing concern for the potential health impact on the increasing number of people living in these areas. In this study, the concentration, the distribution, the contamination levels, and the role of land use were investigated in Erbil metropolis, the capital of Iraqi Kurdistan. A total of 74 soil samples were collected, treated, and analyzed for their physicochemical properties, and for 7 heavy metals (As, Cd, Cr, Cu, Fe, Pb, and Zn) and 16 PAH contents. High concentrations, especially of Cd, Cu Pb, and Zn, were found. The Geoaccumulation index (Igeo), along with correlation coefficients and principal component analysis (PCA) showed that Cd, Cu, Pb, and Zn have similar behaviors and spatial distribution patterns. Heavy traffic density mainly contributed to the high concentrations of these metals. The total concentration of ?PAHs ranged from 24.26 to 6129.14 ng/g with a mean of 2296.1 ng/g. The PAH pattern was dominated by 4- and 5-ring PAHs, while diagnostic ratios and PCA indicated that the main sources of PAHs were pyrogenic. The toxic equivalent (TEQ) values ranged from 3.26 to 362.84 ng/g, with higher values in central parts of the city. A statistically significant difference in As, Cd, Cu, Pb, Zn, and ?PAH concentrations between different land uses was observed. The highest As concentrations were found in agricultural areas while roadside, commercial, and industrial areas had the highest Cd, Cu, Pb, Zn, and ?PAH contents. PMID- 27709465 TI - Leukotriene Receptor Antagonists for the Treatment of Asthma in Elderly Patients. AB - Elderly asthma (EA) is regarded as a distinct phenotype of asthma and is associated with age-related changes in airway structure and alterations in lung function and immune responses. EA is difficult to diagnose because of aging and co-morbidities, and overlaps with fixed airway obstructive disease. Novel modalities to differentiate between EA and chronic obstructive pulmonary disease (COPD) are necessary. A multifaceted approach, including clinical history, smoking habits, atopy, and measurement of lung function, is mandatory to differentiate asthma from COPD. There are a variety of co-morbidities with EA, of which COPD, upper airway diseases, depression, obesity, and hypertension are the most common, and these co-morbidities can affect the control status of EA. However, leukotriene receptor antagonists (LTRAs) can facilitate the management of EA, and thus addition of an LTRA to inhaled corticosteroid (ICS) monotherapy or ICS plus long-acting beta2-agonist therapy improves symptoms in EA patients. LTRA treatment is safe and beneficial in patients who are unable to use inhalation devices properly or who have co-morbid diseases. Therefore, clinical studies targeting a specific population of EA patients are warranted to help achieve a better therapeutic strategy in EA patients.

AB - Hormone therapy (HT) is prescribed during or after menopausal transition to replace the decline in estrogen and progesterone levels. While some studies indicate that estrogen and progesterone depletion in postmenopausal women might carry a significant risk for developing sporadic Alzheimer's disease (sAD), which may be reduced by HT, recent clinical trials oppose this beneficial effect. This review points to possible reasons for these mixed data by considering the issues of both preclinical and clinical trials, in particular, the representativeness of animal models, timing of HT initiation, type of HT (different types of estrogen compounds, estrogen monotherapy vs. estrogen-progesterone combined therapy), mode of drug delivery (subcutaneous, transdermal, oral, or intramuscular), and hormone dosage used, as well as the heterogeneity of the postmenopausal population in clinical trials (particularly considering their sAD stage, anti-AD therapy, and hysterectomy status). Careful planning of future preclinical and clinical HT interventional studies might help to elucidate the effect of HT on cognitive status in postmenopausal women with sAD, which will eventually contribute to more effective sAD prevention and treatment. PMID- 27709470 TI - Prospective, long-term study of the effect of cabergoline on valvular status in patients with prolactinoma and idiopathic hyperprolactinemia. AB - Since the 1990's cabergoline has been the treatment of choice in prolactinoma, as it permits rapid and effective hormonal and tumor control in most cases. Evidence of cardiac valvulopathy was demonstrated in Parkinson's disease patients treated with dopamine agonists. Retrospective studies in prolactinoma patients treated with cabergoline at lower doses did not show such an effect. However, few prospective data with long-term follow-up are available. The aim of this study was to assess the safety of cabergoline regarding cardiac valvular status during prospective follow-up in patients treated for prolactinoma or idiopathic hyperprolactinemia. We report here a series of 100 patients (71F; median age at diagnosis: 41.5 years) treated with cabergoline for endocrine diseases (prolactinoma n = 89, idiopathic hyperprolactinemia n = 11). All patients underwent complete transthoracic echocardiographic studies at baseline and during long-term prospective surveillance using the same equipment and performed by the same technicians. The median interval between baseline and last follow-up echocardiographic studies while on cabergoline was 62.5 months (interquartile range: 34.75-77.0). The median total duration of cabergoline treatment was 124.5 months (interquartile range: 80.75-188.75) and the median cumulative total dose of cabergoline was 277.8 mg (interquartile range : 121.4-437.8 mg) at last follow up. We found no clinically relevant alterations in cardiac valve function or valvular calcifications with cabergoline treatment. Our data suggest that findings from retrospective analyses are correct and that cabergoline is a safe chronic treatment at the doses used typically in endocrinology. PMID- 27709471 TI - Natural history of graves' orbitopathy after treatment. AB - Intravenous glucocorticoids are used for Graves' orbitopathy, alone or associated with/followed by additional treatments (orbital radiotherapy, orbital decompression, palpebral or eye surgery). However, the relation between associated/additional treatments and other variables with Graves' orbitopathy outcome following intravenous glucocorticoids is not clear. Thus, the present study was conducted to investigate retrospectively the impact of associated/additional treatments and other variables on Graves' orbitopathy outcome after intravenous glucocorticoids. We evaluated 226 untreated Graves' orbitopathy patients. Following first observation, patients were given intravenous glucocorticoids and re-examined after a median of 46.5 months. The end-points were the relation between Graves' orbitopathy outcome, outcome of NOSPECS score and of the single Graves' orbitopathy features with several variables, including associated/additional treatments. All Graves' orbitopathy features improved significantly after treatment. Overall, Graves' orbitopathy improved in ~60 % of patients (responders), whereas it was stable or worsened in ~40 % of patients (non-responders). Time between first and last observation and clinical activity score at first observation correlated significantly with Graves' orbitopathy outcome. The outcomes of NOSPECS, eyelid aperture, clinical activity score and diplopia correlated with time between the first and last observation. The NOSPECS outcome correlated with gender. The outcomes of proptosis, eyelid aperture and visual acuity correlated with orbital decompression. The outcome of diplopia correlated with orbital radiotherapy. Taking into account the limitations of retrospective investigations, our findings confirm that time (i.e. the natural history of Graves' orbitopathy) is a key factor in determining the long-term outcome of Graves' orbitopathy, radiotherapy is effective for diplopia, and orbital decompression is followed by an amelioration of several Graves' orbitopathy features. PMID- 27709472 TI - The effect of TSH change per year on the risk of incident chronic kidney disease in euthyroid subjects. AB - The objective of this study is to evaluate the predictive values of baseline thyroid-stimulating hormone and the rate of thyroid-stimulating hormone change within the euthyroid state on the development of chronic kidney disease. We conducted a longitudinal study in 17,067 Korean adults with normal thyroid function and no history of thyroid disease. Incident chronic kidney disease was defined as an estimated glomerular filtration rate <60 ml/min/1.73 m2. The rate of thyroid-stimulating hormone change was determined by subtracting the baseline thyroid-stimulating hormone level from the thyroid-stimulating hormone level measured at the last visit prior to the diagnosis of chronic kidney disease or at the final visit in subjects without chronic kidney disease, divided by the observation period (years). Subjects were stratified into quintiles according to rates of thyroid-stimulating hormone change. During 86,583 person-years of follow up (median follow-up 5.2 years), there were 561 incident cases of chronic kidney disease. The risk of incident chronic kidney disease was significantly higher in subjects with rapid increases (quintile 5) or decreases (quintile 1) in thyroid stimulating hormone levels compared to the reference group (quintile 3). In fully adjusted models, the hazard ratios of quintiles 1 and 5 were 3.15 (95 % confidence interval 2.34 to 4.24; p < 0.001) and 3.37 (95 % confidence interval 2.52 to 4.51; p < 0.001), respectively. However, there was no significant association between baseline thyroid-stimulating hormone and risk of incident chronic kidney disease. The development of chronic kidney disease is associated with the rate of changes in thyroid-stimulating hormone level rather than with baseline thyroid-stimulating hormone levels. PMID- 27709473 TI - Multiparametric ultrasonography and ultrasound elastography in the differentiation of parathyroid lesions from ectopic thyroid lesions or lymphadenopathies. AB - To evaluate the accuracy of ultrasound elastography with ElastoscanTM Core Index in the differential diagnosis of parathyroid lesions from ectopic thyroid nodules and lymph nodes. Seventy nine patients with repeatedly high levels of circulating intact parathyroid hormone, normal vitamin D and renal function tests, with an ultrasound scan showing a neck lesion, sharply demarcated from the thyroid lobules, were consecutively enrolled. Ultrasound with and without Color Doppler and ultrasound elastography were performed before histological examination. All ultrasound features, vascularization and ultrasound elastography diagnostic performance were assessed using ROC curves. Histological examination confirmed 47 parathyroid lesions, 18 thyroid ectopic nodules and 14 reactive lymph nodes. In distinguishing parathyroid from thyroid nodules, shape had a 100 % sensitivity (95 % CI 92.4-100) and 50 % specificity (95 % CI 37.2-64.7), cleavage had a 85.1 % sensitivity (95 % CI 72.3-92.6) and 77.8 % specificity (95 % CI 65.1-88) while peripheral vascularization had a sensitivity of 91.5 (95 % CI 79.6-97.6) and specificity of 72.2 (95 % CI 46.5-90.3). An ElastoscanTM Core Indexof 1.28 was 46 % sensitive (95 % CI 33.4-58.7) and 77 % specific (95 % CI 66.2-89.1) in discriminating parathyroid lesions from thyroid nodules. An ElastoscanTM Core Index of 1.0 was 78 % sensitive (95 % CI 65.1-88) and 71 % specific (95 % CI 56 81.3) in discriminating parathyroid lesions from lymph nodes (p = 0.045). An ElastoscanTM Core Index greater than 2.58 had a 100 % sensitivity (95 % CI 43.8 100) and 95.4 % specificity (95 % CI 38.3-99.7) in discriminating malignant from benign parathyroid nodules. ElastoscanTM Core Index was significantly higher in thyroid nodules than in reactive lymph nodes (1.18 +/- 0.62, p = 0.008). The ultrasound features of cleavage and peripheral vascularization help to differentiate parathyroid from thyroid nodules. ElastoscanTM Core Index can improve ultrasound discrimination of parathyroid lesions from lymph nodes. The ElastoscanTM Core Index is significantly higher in malignant than in benign parathyroid lesions.

AB - Tumor-induced osteomalacia is a rare acquired metabolic bone disorder characterized by isolated renal phosphate wasting due to abnormal tumor production of fibroblast growth factor 23. We report the case of a 59 year old woman referred to our department with a long history of progressive diffuse muscle weakness and pain, generalized bone pains and multiple insufficiency fractures of heels, ankles and hips due to a hypophosphatemic osteomalacia. A fibroblast growth factor 23-producing phosphaturic mesenchymal tumor localized in the left quadriceps femoris muscle was identified 7 years after onset of symptoms. Excision of the tumor resulted in normalization of serum phosphate and fibroblast growth factor 23 levels and in complete resolution of the clinical picture with disappearance of all musculoskeletal symptoms. This case illustrates the diagnostic difficulties in establishing a diagnosis tumor-induced osteomalacia and in identifying the responsible tumor. Our case underscores the clinical need to investigate all patients with persistent musculoskeletal symptoms for hypophosphatemia. A systematic approach is of pivotal importance because early recognition and treatment of the metabolic abnormality can prevent deleterious effects of osteomalacia on the skeleton. PMID- 27709475 TI - Differentiated thyroid carcinoma: Incremental diagnostic value of 131I SPECT/CT over planar whole body scan after radioiodine therapy. AB - The purpose of this prospective study was to determine the incremental diagnostic value of single photon emission computed tomography/computed tomography with iodine-131 over planar whole body scan in the staging of patients with differentiated thyroid carcinoma. A total of 365 patients (270 female, 95 male) with differentiated thyroid carcinoma were treated with radioiodine therapy for thyroid remnant ablation with radical intent after thyroidectomy between January 2013 and November 2014. In addition to planar whole body scan, single photon emission computed tomography/computed tomography of neck and chest were performed. Each radioactive focus at whole body scan was classified as positive or equivocal with respect of specific territories: thyroid bed, cervical lymph nodes and distant metastases.Whole-body scan detected focal uptake in 353 patients and no uptake in 12. The location was considered equivocal in 100. Single photon emission computed tomography/computed tomography detected focal uptake in 356 patients and no uptake in nine. In three patients with negative wholebody scan, single photon emission computed tomography/computed tomography provided information about residual activity in the thyroid bed. By single photon emission computed tomography/computed tomography the location was equivocal in 18 patients only. Single photon emission computed tomography/computed tomography was helpful in 82 out of 100 patients with equivocal findings by whole body scan allowing a correct identification of the uptake sites. In a great number of equivocal whole body scan, due to high remnant activity, single photon emission computed tomography/computed tomography was able to differentiate between thyroid remnant and lymph nodes uptake. In 22 out of 100 patients with doubtful whole body scan, single photon emission computed tomography/computed tomography correctly identified nodal or distant metastases, and in 2/100 patients, focal uptake classified as metastatic by whole body scan was reclassified as para physiological by single photon emission computed tomography/computed tomography. The TNM classification changed in 13 out of 22 patients. Single photon emission computed tomography/computed tomography improves detection and localization of the iodine-131 uptake after thyroidectomy in patients with differentiated thyroid carcinoma and it is more accurate than whole body scan to evaluate lymph nodes and to identify and characterize distant metastases. Single photon emission computed tomography/computed tomography aids assessment of lower/upper stage in a significant number of patients with differentiated thyroid carcinoma and it can affect therapy decision-making and patient management. PMID- 27709485 TI - Pediatric anterior cruciate ligament reconstruction outcomes. AB - Treatment of pediatric anterior cruciate injuries have become an area of controversy sparking much debate about best management strategies. Delaying surgery until skeletal maturity has often been shown to result in unfavorable outcomes due to concomitant meniscal and chondral injuries in this population. There have been numerous techniques used to reconstruct the ACL in the skeletally immature patient; however, most studies are limited by small patient numbers and other methodological concerns. With recent publications reporting failure rates as high as 15-25 % and growth disturbances being uncommon but now reported within almost every technical category, patient and caregiver education become of paramount importance. Key principles will be outlined that may help to avoid some of the pitfalls that occur when dealing with this unique population. PMID- 27709476 TI - Parenchyma-sparing surgery for pancreatic endocrine tumors. AB - Enucleation (EN) and middle pancreatectomy (MP) have been proposed as a treatment for G1 and G2 pancreatic neuroendocrine tumors (PNET). The aim of this study is to analyze the outcomes of parenchyma-sparing surgery (PSS) for PNET in an Italian high-volume center. All patients with a histological diagnosis of PNET who underwent surgical resection in our center between January 2010 and January 2016 were included in the study. Demographic, perioperative, and discharge data were collected in a prospective database. Follow-up was considered until March 31, 2016. 99 patients were included. PSS was performed in 22 cases (22.2 %), 18 EN (82 %), and 4 MP (18 %). 89.8 % patients were staged with CT scan, 69.6 % with endoscopic ultrasonography, 48.4 % with MRI, and 47.4 % with 68Ga-PET. Pre operative histological diagnosis was obtained in 68.6 %. Most of PSS tumors were G1 (n = 15; 68 %) and there were no G3. Nodal sampling was performed in every PSS. Only two patients showed nodal metastatic disease. The median post-operative length of stay was 7 days after PSS. Eleven (50 %) of these patients developed a complication; two (18.2 %) were major complications. Pancreatic fistula developed in ten patients (45.5 %); two (20 %) were type B. There were no type C fistula and no re-operations after PSS. Readmission rate was 9 %. All patients submitted to PSS are alive and free of recurrence. PSS is a safe technique for G1 and G2 PNETs, but it has to be conducted in experienced centers and an extensive nodal sampling and a long follow-up are required for the best oncologic outcome. PMID- 27709486 TI - Lower extremity growth and deformity. AB - The pediatric lower extremity has well known growth patterns. When deformities or growth disturbances occur, there are several methods to measure and predict the resulting discrepancy, including the Green-Anderson, Moseley, and Multiplier methods. Many techniques exist to correct leg length discrepancy and deformity such and temporary epiphysiodesis, permanent epiphysiodesis, external fixators, and internal lengthening devices. All of these methods have numerous complications and limitations; however, with careful planning and patient selection, length and alignment can be improved with high patient satisfaction. PMID- 27709488 TI - Criteria for Inclusion of Newer Bariatric and Metabolic Procedures into the Mainstream: a Survey of 396 Bariatric Surgeons. AB - BACKGROUND: There is currently no consensus on the criteria for inclusion of new bariatric procedures into routine clinical practice. This study canvasses bariatric surgeons in an attempt to define these criteria. METHODS: Bariatric Surgeons from around the world were invited to participate in a questionnaire based survey on SurveyMonkey (r). RESULTS: 396 bariatric surgeons, 337 International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) members, took the survey. Five clinical studies conducted under the strict monitoring of an Institutional Review Board would satisfy most surgeons (67.7 %, n = 266). When asked regarding the number of patients in these studies, a cumulative number of 500 patients would satisfy 64.5 % (n = 255) of the surgeons. Most respondents regarded endorsement by their national society and IFSO as 'very important' or 'extremely important'. An overwhelming 74.4 % (n = 294) felt that every new procedure should undergo a randomized comparison against one of the established alternatives like Roux-en-Y Gastric Bypass or Sleeve Gastrectomy. CONCLUSION: Evaluation of a new bariatric procedure in at least 5 adequately supervised clinical studies (four of which must be randomized comparisons with one of the existing alternatives) reporting at least 5 years results on a minimum of 500 patients would satisfy majority of bariatric surgeons for the inclusion of a new bariatric procedure into clinical practice. The findings of this survey are simply aimed at starting a discussion on this topic and cannot be used to influence the ground reality until an international consensus can be reached amongst experts. PMID- 27709487 TI - Long-Term Outcomes in Patients with Morbid Obesity and Type 1 Diabetes Undergoing Bariatric Surgery. AB - BACKGROUND: This study aims to describe the long-term outcomes of bariatric surgery in a cohort of patients with type 1 diabetes (T1DM). METHODS: Thirty-two patients with T1DM and initial BMI of 41.3 +/- 4.8 kg/m2 were studied, 18.7 % undergoing duodenal switch (DS), 34.4 % gastric bypass, and 46.9 % sleeve gastrectomy and followed-up after surgery for 4.6 +/- 2.6 years. Changes in BMI, HbA1c, insulin requirements, evolution of comorbidities, and microvascular complications were registered annually after surgery. RESULTS: Percentage of total weight loss (%TWL) 12 months after surgery was 30.4 +/- 9.2 % and at 5 years, it decreased to 28.1 +/- 11.5 % (p = 0.02). HbA1c was reduced during the first year from 8.5 +/- 1.3 to 7.9 +/- 1.4 %, p = 0.016. In the long-term, HbA1c returned to baseline values. There was a sustained reduction of 51 % in total daily insulin dose, and the decrease in the number of patients with hypertension, dyslipidemia, and obstructive sleep apnea was 42.8, 25, and 66 %, respectively. Retinopathy remained mainly unaffected, and 25 % of patients with microalbuminuria regressed to normoalbuminuria. CONCLUSIONS: Bariatric surgery in patients with T1DM mainly provides benefits of weight reduction, on insulin requirements, obesity comorbidities, and some benefits in diabetes complications, but might have only minimal effect on the glycemic control in the long term. This trial was registered at www.controlledtrials.com as ISRCTN49980913. PMID- 27709489 TI - The role of FDG-PET/CT in preoperative staging of sentinel lymph node biopsy positive melanoma patients. AB - BACKGROUND: On April 1, 2015, Odense University Hospital (OUH) began a new diagnostic strategy, wherein all malignant melanoma (MM) patients in the Region of Southern Denmark with a positive sentinel lymph node biopsy (SLNB) underwent FDG-PET/CT preoperatively prior to lymph node dissection (LND). The purpose of this study is to determine FDG-PET/CT's efficacy in finding distant metastasis in the first year after the implementation of this new strategy, and to what extent these findings influence subsequent diagnostic testing and treatment in this patient group. We conducted a retrospective multicenter cohort study which included all patients with MM from all hospitals in the Region of Southern Denmark from April 1, 2015 to April 1, 2016 found to be SLNB-positive who subsequently underwent FDG-PET/CT. Patient information was acquired from the Danish Melanoma Database and was cross-referenced with OUH's patient records. The data was analyzed for a number of parameters including FDG-PET/CT findings and treatment strategy. Median follow-up time was 7 months. RESULTS: A total of 47 patients were eligible from the first year of this new diagnostic strategy. One patient was excluded due to undergoing LND prior to FDG-PET/CT. Thus, 46 patients were included in this study. Ultimately, preoperative FDG-PET/CT neither uncovered any distant metastases nor led to any alterations in treatment strategy in this patient group. CONCLUSIONS: Surprisingly, this new diagnostic strategy did not find any MM metastases or uncover anything else of relevance. FDG-PET/CT did, however, provide false positive findings in 13 % (6/46) of these patients. These scans triggered additional, predominantly invasive, procedures, which did not ultimately have an impact on the therapeutic strategy. Thus, these findings indicate a need for re-evaluation of this new diagnostic strategy as well as the necessity for further clinical trials evaluating FDG-PET/CT's utility in this clinical setting. PMID- 27709490 TI - Atorvastatin Protects from Abeta1-40-Induced Cell Damage and Depressive-Like Behavior via ProBDNF Cleavage. AB - Intracerebroventricular (icv) amyloid-beta (Abeta)1-40 infusion to mice has been demonstrated to cause neurotoxicty and depressive-like behavior and it can be used to evaluate antidepressant and neuroprotective effect of drugs. Atorvastatin is a widely used statin that has demonstrated antidepressant-like effect in predictable animal behavioral models and neuroprotective effect against Abeta1-40 infusion. The purpose of this study was to determine the effect of in vivo atorvastatin treatment against Abeta1-40-induced changes in mood-related behaviors and biochemical parameters in ex vivo hippocampal slices from mice. Atorvastatin treatment (10 mg/kg, p.o., once a day for seven consecutive days) abolished depressive-like and anhedonic-like behaviors induced by Abeta1-40 (400 pmol/site, icv) infusion. Abeta1-40-induced hippocampal cell damage was reversed by atorvastatin treatment. Abeta1-40 infusion decreased glutamate uptake in hippocampal slices, and atorvastatin did not altered it. Glutamine synthetase activity was not altered by any treatment. Atorvastatin also increased hippocampal mature brain-derived neurotrophic factor (mBDNF)/precursor BDNF (proBDNF) ratio, suggesting an increase of proBDNF to mBDNF cleavage. Accordingly, increased tissue-type plasminogen activator (tPA) and p11 genic expression were observed in hippocampus of atorvastatin-treated mice. Atorvastatin displays antidepressant-like and neuroprotective effects against Abeta1-40-induced toxicity, and these effects may involve tPA- and p11-mediated cleavage of proBDNF to mBDNF. PMID- 27709492 TI - C5a/C5aR Pathway Plays a Vital Role in Brain Inflammatory Injury via Initiating Fgl-2 in Intracerebral Hemorrhage. AB - Intracerebral hemorrhage (ICH) is a serious emergency with high mortality and morbidity. Up to date, a limited understanding of ICH pathogenesis is difficult to implement effective therapeutic strategy. Much evidence demonstrates that the complement cascade is activated after experimental ICH. However, the exact mechanism has not been well studied in ICH. In the current study, C57BL/6J mice were injected with autologous whole blood. C5a/C5aR levels, microglia infiltration, inflammatory cytokine, and fibrinogen-like protein 2 (Fgl-2) expression in the perihematomal region were analyzed following ICH. In addition, brain water content and neurological dysfunction were detected following ICH. Our data demonstrated that ICH induced complement activation, along with an increase of C5a/C5aR levels, microglia infiltration, and inflammatory cytokine levels. However, C5aR-/- mice exhibited significant attenuation of inflammatory reaction, accompanied by a remarkable reduction of Fgl-2, brain water content, and neurological dysfunction. Furthermore, inhibiting extracellular signal-regulated kinase 1/2 (ERK1/2) and p38 efficiently inhibited C5a-mediated Fgl-2 production following ICH. Taken together, these data suggest that C5a/C5aR plays a vital role in the ICH-induced inflammatory damage via Fgl-2, and ERK1/2 and p38 pathways also are involved in the pathogenesis of ICH. Therefore, inhibition of C5a/C5aR activation might enlarge our insights in ICH therapy. PMID- 27709491 TI - P2X3 and P2X2/3 Receptors Play a Crucial Role in Articular Hyperalgesia Development Through Inflammatory Mechanisms in the Knee Joint Experimental Synovitis. AB - Osteoarthritis (OA) is a degenerative and progressive disease characterized by cartilage breakdown and by synovial membrane inflammation, which results in disability, joint swelling, and pain. The purinergic P2X3 and P2X2/3 receptors contribute to development of inflammatory hyperalgesia, participate in arthritis processes in the knee joint, and are expressed in chondrocytes and nociceptive afferent fibers innervating the knee joint. In this study, we hypothesized that P2X3 and P2X2/3 receptors activation by endogenous ATP (adenosine 5' triphosphate) induces articular hyperalgesia in the knee joint of male and female rats through an indirect sensitization of primary afferent nociceptors dependent on the previous release of pro-inflammatory cytokines and/or on neutrophil migration. We found that the blockade of articular P2X3 and P2X2/3 receptors significantly attenuated carrageenan-induced hyperalgesia in the knee joint of male and estrus female rats in a similar manner. The carrageenan-induced knee joint inflammation increased the expression of P2X3 receptors in chondrocytes of articular cartilage. Further, the blockade of articular P2X3 and P2X2/3 receptors significantly reduced the increased concentration of TNF-alpha, IL-6, and CINC-1 and the neutrophil migration induced by carrageenan. These findings indicate that P2X3 and P2X2/3 receptors activation by endogenous ATP is essential to hyperalgesia development in the knee joint through an indirect sensitization of primary afferent nociceptors dependent on the previous release of pro inflammatory cytokines and/or on neutrophil migration. PMID- 27709493 TI - G-CSF-mobilized Bone Marrow Mesenchymal Stem Cells Replenish Neural Lineages in Alzheimer's Disease Mice via CXCR4/SDF-1 Chemotaxis. AB - Recent studies reported granulocyte colony-stimulating factor (G-CSF) treatment can improve the cognitive function of Alzheimer's disease (AD) mice, and the mobilized hematopoietic stem cells (HSCs) or bone marrow mesenchymal stem cells (BM-MSCs) are proposed to be involved in this recovery effect. However, the exact role of mobilized HSC/BM-MSC in G-CSF-based therapeutic effects is still unknown. Here, we report that C-X-C chemokine receptor type 4 (CXCR4)/stromal cell-derived factor 1 (SDF-1) chemotaxis was a key mediator in G-CSF-based therapeutic effects, which was involved in the recruitment of repair-competent cells. Furthermore, we found both mobilized HSCs and BM-MSCs were able to infiltrate into the brain, but only BM-MSCs replenished the neural lineage cells and contributed to neurogenesis in the brains of AD mice. Together, our data show that mobilized BM-MSCs are involved in the replenishment of neural lineages following G-CSF treatment via CXCR4/SDF-1 chemotaxis and further support the potential use of BM-MSCs for further autogenically therapeutic applications. PMID- 27709496 TI - Dietary Supplementation of Magnesium Oxide (MgO) Nanoparticles for Better Survival and Growth of the Freshwater Prawn Macrobrachium rosenbergii Post larvae. AB - This study was performed to assess the growth-promoting potential of dietary magnesium oxide nanoparticles (MgO NPs) in Macrobrachium rosenbergii post-larvae (PL). MgO NPs were supplemented at 0, 100, 200, 300, 400 and 500 mg kg-1 with the basal diet (containing 0.95 g Mg kg-1); the concentrations of Mg in MgO NP supplemented diets were increased correspondingly (1.07, 1.15, 1.24, 1.37 and 1.46 g Mg kg-1 respectively). MgO NP-supplemented diets were fed to M. rosenbergii PL (initial weight 0.11 +/- 0.04 g) for a period of 90 days. In the carcasses of experimental prawns, the content of Mg was found to be elevated significantly with respect to the individual diet (102.14, 183.29, 205.46, 221.03, 237.10 and 254.36 MUg Mg g-1 respectively) when compared with that of the control. The contents of Cu, Zn, Fe, Ca, Na and K levels were also found to be elevated in the carcasses of experimental prawns. Significant (P < 0.05) improvements were observed in nutritional indices [survival rate (SR), weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR) and protein efficiency ratio (PER)], activities of digestive enzymes (protease, amylase and lipase), concentrations of basic biochemical constituents (total protein, amino acid, carbohydrate, lipid, profiles of amino acids and fatty acids) and population of haemocytes [total and differential (hyalinocytes, semigranulocytes and granulocytes)] in all the test PL. Maximum performance was recorded in 500 mg kg-1 MgO NP-supplemented-feed-fed PL. There were no significant elevations recorded in activities of antioxidant enzymes [superoxide dismutase (SOD) and catalase (CAT)], lipid peroxidation (LPO) and metabolic enzymes [glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT)] recorded in any of the MgO NP-supplemented-feed-fed PL when compared with the control. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) showed increases in the staining intensity of polypeptide bands resolved in 500 mg kg-1 MgO NP-supplemented-feed-fed PL when compared with the control. Based on the gradual improvement in attaining survival, growth, FCR, biochemical constituents and haemocyte population, this study recommends MgO NP supplementation of 500 mg kg-1 for sustainable maintenance of M. rosenbergii PL. As the studied highest concentration of MgO NPs showed the best performance, it is necessary to study with beyond 500 mg kg-1 of MgO NPs to optimize the actual concentration. PMID- 27709494 TI - Identification of Noncanonical Wnt Receptors Required for Wnt-3a-Induced Early Differentiation of Human Neural Stem Cells. AB - Wnt proteins preferentially activate either beta-catenin-dependent or beta catenin-independent signals, but the activity of a particular Wnt also depends on cellular context and receptor availability. We previously reported that Wnt-3a induces neural differentiation of human embryonic stem cell-derived neural stem cells (NSCs) in a beta-catenin-independent manner by activating a signal involving JNK and the AP-1 family member ATF-2. Here, we report the results of a gene silencing approach to identify the Wnt receptors that mediate this response to Wnt-3a. Silencing of ROR2 increased neuronal differentiation, as measured by expression of the genes DCX, NEUROD1, and NGN1, suggesting ROR2 signals normally prevent differentiation. Silencing of the other Wnt receptors singly did not affect Wnt-3a-induced neuronal differentiation. However, pairwise silencing of ROR1 and FZD4 or FZD5 and of LRP6 and FZD4 or FZD5 inhibited neuronal differentiation, as detected by reductions in the expression of neuronal genes and immunocytochemical detection of DCX, NEUROD1 and DCX. Ectopic expression of these receptors in HEK 293 cells increased ATF2-dependent transcription. In addition, ROR1 coimmunoprecipitated with FZD4 and LRP6 in transfected HEK 293 cells and colocalized with FZD4 and with LRP6 at the cell surface of transfected L cells. Wnt-3a did not appear to affect these interactions but did alter the interactions between LRP6 and FZD4/5. Together, these observations highlight roles for ROR1, LRP6, FZD4, and FZD5 in neural stem cell differentiation and provide support for a model in which dynamic interactions among these receptors mediate Wnt-3a activation of ATF2 signaling. PMID- 27709497 TI - Cardioprotective Effect of Selenium Against Cyclophosphamide-Induced Cardiotoxicity in Rats. AB - The objective of this study is to evaluate the possible protective effects of selenium (Se) against cyclophosphamide (CP)-induced acute cardiotoxicity in rats. A total of 42 male Spraque-Dawley rats were divided into six groups (n = 7). Rats in the first group were served as control. Rats in the second group received CP (150 mg/kg) at the sixth day of experiment. Animals in the third and fourth groups were treated with only 0.5 and 1 mg/kg Se respectively for six consecutive days. Rats in the fifth and sixth groups received respective Se doses (0.5 or 1 mg/kg) for 6 days and then a single dose of CP administered on the sixth day. On day 7, the animals were sacrificed; blood samples were collected to measure malondialdehyde (MDA), glutathione (GSH), lactate dehydrogenase (LDH), creatine kinase-MB (CK-MB), and ischemia-modified albumin (IMA) levels. Heart tissues were processed routinely and tissue sections were stained with H + E for light microscopic examination. In the CP-treated rats MDA, LDH, CK-MB, and IMA serum levels increased, while GSH levels decreased. Microscopic evaluation showed that tissue damage was conspicuously lower in CP plus Se groups. Moreover, 1 mg/kg Se was more protective than 0.5 mg/kg Se as indicated by histopathological and biochemical values. In conclusion, Se is suggested to be a potential candidate to ameliorate CP-induced cardiotoxicity which may be related to its antioxidant activity. PMID- 27709495 TI - Evidence for a Link Between Fkbp5/FKBP5, Early Life Social Relations and Alcohol Drinking in Young Adult Rats and Humans. AB - Alcohol misuse has been linked to dysregulation of stress, emotion, and reward brain circuitries. A candidate key mediator of this association is the FK506 binding protein (FKBP5), a negative regulator of the glucocorticoid receptor. The aim of the present study was to further understand the Fkbp5/FKBP5-related genetic underpinnings underlying the relationship between early life social relations and alcohol drinking. The effect of maternal separation and voluntary alcohol drinking on Fkbp5 expression was investigated in the brain of young adult rats, whereas the interaction effect of the functional FKBP5 single nucleotide polymorphism rs1360780 genotype and parent-child relationship on problematic drinking was examined in young adult humans. In rats, Fkbp5 expression in the nucleus accumbens and ventral tegmental area, core regions of the reward system, was affected in a region-dependent manner and in opposite direction by maternal separation and alcohol drinking. Fkbp5 expression in the cingulate cortex was affected by the combined effect of maternal separation and alcohol drinking. In humans, the TT genotype, in the presence of a poor relationship between the child and parents, was associated with problematic drinking behavior. The present findings suggest that Fkbp5 expression in mesocorticolimbic dopaminergic regions associates with early life stress-mediated sensitivity to alcohol drinking and that FKBP5 genotype interacts with parent-child relationship to influence alcohol drinking. These findings are the first to point to a role of FKBP5 in propensity to alcohol misuse and call for studies of the underlying molecular mechanisms to identify potential drug targets. PMID- 27709498 TI - Aluminum-Induced Cholinergic Deficits in Different Brain Parts and Its Implications on Sociability and Cognitive Functions in Mouse. AB - Aluminum is associated with etiology of many neurodegenerative diseases specially Alzheimer's disease. Chronic exposure to aluminum via drinking water results in aluminum deposition in the brain that leads to cognitive deficits. The study aimed to determine the effects of aluminum on cholinergic biomarkers, i.e., acetylcholine level, free choline level, and choline acetyltransferase gene expression, and how cholinergic deficit affects novel object recognition and sociability in mice. Mice were treated with AlCl3 (250 mg/kg). Acetylcholine level, free choline level, and choline acetyltransferase gene expression were determined in cortex, hippocampus, and amygdala. The mice were subjected to behavior tests (novel object recognition and social novelty preference) to assess memory deficits. The acetylcholine level in cortex and hippocampus was significantly reduced in aluminum-treated animals, as compared to cortex and hippocampus of control animals. Acetylcholine level in amygdala of aluminum treated animals remained unchanged. Free choline level in all the three brain parts was found unaltered in aluminum-treated mice. The novel object recognition memory was severely impaired in aluminum-treated mice, as compared to the control group. Similarly, animals treated with aluminum showed reduced sociability compared to the control mice group. Our study demonstrates that aluminum exposure via drinking water causes reduced acetylcholine synthesis in spite of normal free choline availability. This deficit is caused by reduced recycling of acetylcholine due to lower choline acetyltransferase level. This cholinergic hypofunction leads to cognitive and memory deficits. Moreover, hippocampus is the most affected brain part after aluminum intoxication. PMID- 27709505 TI - A novel thymidine phosphorylase mutation in a Chinese MNGIE patient. AB - Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive disorder associated with mitochondrial alterations. MNGIE is characterized by severe gastrointestinal dysmotility, cachexia, ophthalmoplegia, ptosis, peripheral neuropathy, and leukoencephalopathy. The condition is caused by mutation of the TYMP gene. We studied the clinical and biochemical characteristics of a family with MNGIE. The proband was a 48-year-old male presenting with diarrhea and progressive weight loss. He also had ptosis and exhibited eyeball fixation. His blood and cerebrospinal fluid lactate levels were elevated. Magnetic resonance imaging of the brain revealed diffuse leukoencephalopathy. Ragged red fibers and cytochrome c oxidase-deficient fibers were apparent on muscle biopsy. His vision and ptosis deteriorated significantly during follow-up. Our clinical diagnosis of MNGIE was confirmed by TYMP gene analysis. We discovered a homozygous TYMP c.1193-1216 dup GGGCGCTGCCGCTGGCGCTGGTGC mutation (a duplication). Some of the family members were heterozygous for the mutation but had no clinical features. We predicted the function of this mutation using PredictProtein and found that the secondary structure had changed in the region of the helix and strand, the transmembrane region, and the protein-protein binding sites. The family described herein exhibited biochemically, genetically, and functionally confirmed MNGIE syndrome. PMID- 27709504 TI - Understanding Long-Term Outcomes Following Sepsis: Implications and Challenges. AB - Sepsis is life-threating organ dysfunction due to infection. Incidence of sepsis is increasing and the short-term mortality is improving, generating more sepsis survivors. These sepsis survivors suffer from additional morbidities such as higher risk of readmissions, cardiovascular disease, cognitive impairment and of death, for years following index sepsis episode. In the first year following index sepsis episode, approximately 60 % of sepsis survivors have at least one rehospitalisation episode, which is most often due to infection and one in six sepsis survivors die. Sepsis survivors also have a higher risk of cognitive impairment and cardiovascular disease contributing to the reduced life expectancy seen in this population, when assessed with life table comparisons. For optimal design of interventional trials to reduce these bad outcomes in sepsis survivors, in-depth understanding of major risk factors for these morbid events, their modifiability and a causal relationship to the pathobiology of sepsis is essential. This review highlights the recent advances, clinical and methodological challenges in our understanding of these morbid events in sepsis survivors.

AB - Anti-diabetic drugs are widely used and are essential for adequate glycemic control in patients with type 2 diabetes. Recently, marketed anti-diabetic drugs include incretin-based therapies (GLP-1 receptor agonists and DPP-4 inhibitors) and sodium-glucose co-transporter 2 (SGLT2) inhibitors. In contrast to well-known detrimental effects of thiazolidinediones on bone metabolism and fracture risk, clinical data on the safety of incretin-based therapies is limited. Based on meta analyses of trials investigating the glycemic-lowering effect of GLP-1 receptor agonists and DPP4 inhibitors, it seems that incretin-based therapies are not associated with an increase in fracture risk. Sodium-glucose co-transporter 2 inhibitors may alter calcium and phosphate homeostasis as a result of secondary hyperparathyroidism induced by increased phosphate reabsorption. Although these changes may suggest detrimental effects of SGLT-2 inhibitors on skeletal integrity, treatment-related direct effects on bone metabolism seem unlikely. Observed changes in BMD, however, seem to result from increased bone turnover in the early phase of drug-induced weight loss. Fracture risk, which is observed in older patients with impaired renal function and elevated cardiovascular disease risk treated with SGLT2 inhibitors, seems to be independent of direct effects on bone but more likely to be associated with falls and changes in hydration status secondary to osmotic diuresis. PMID- 27709510 TI - Where Does the Electron Go? Stable and Metastable Peptide Cation Radicals Formed by Electron Transfer. AB - Electron transfer to doubly and triply charged heptapeptide ions containing polar residues Arg, Lys, and Asp in combination with nonpolar Gly, Ala, and Pro or Leu generates stable and metastable charge-reduced ions, (M + 2H)+?, in addition to standard electron-transfer dissociation (ETD) fragment ions. The metastable (M + 2H)+? ions spontaneously dissociate upon resonant ejection from the linear ion trap, giving irregularly shaped peaks with offset m/z values. The fractions of stable and metastable (M + 2H)+? ions and their mass shifts depend on the presence of Pro-4 and Leu-4 residues in the peptides, with the Pro-4 sequences giving larger fractions of the stable ions while showing smaller mass shifts for the metastables. Conversion of the Asp and C-terminal carboxyl groups to methyl esters further lowers the charge-reduced ion stability. Collisional activation and photodissociation at 355 nm of mass-selected (M + 2H)+? results in different dissociations that give sequence specific MS3 spectra. With a single exception of charge-reduced (LKGLADR + 2H)+?, the MS3 spectra do not produce ETD sequence fragments of the c and z type. Hence, these (M + 2H)+? ions are covalent radicals, not ion-molecule complexes, undergoing dramatically different dissociations in the ground and excited electronic states. The increased stability of the Pro-4 containing (M + 2H)+? ions is attributed to radicals formed by opening of the Pro ring and undergoing further stabilization by hydrogen atom migrations. UV-VIS photodissociation action spectroscopy and time dependent density functional theory calculations are used in a case in point study of the stable (LKGPADR + 2H)+? ion produced by ETD. In contrast to singly reduced peptide ions, doubly reduced (M + 3H)+ ions are stable only when formed from the Pro-4 precursors and show all characteristics of even electron ions regarding no photon absorption at 355 nm or ion-molecule reactions, and exhibiting proton driven collision induced dissociations. Graphical Abstract ?. PMID- 27709511 TI - Quantitation of the Noncovalent Cellular Retinol-Binding Protein, Type 1 Complex Through Native Mass Spectrometry. AB - Native mass spectrometry (MS) has become a valuable tool in probing noncovalent protein-ligand interactions in a sample-efficient way, yet the quantitative application potential of native MS has not been fully explored. Cellular retinol binding protein, type I (CrbpI) chaperones retinol and retinal in the cell, protecting them from nonspecific oxidation and delivering them to biosynthesis enzymes where the bound (holo-) and unbound (apo-) forms of CrbpI exert distinct biological functions. Using nanoelectrospray, we developed a native MS assay for probing apo- and holo-CrbpI abundance to facilitate exploring their biological functions in retinoid metabolism and signaling. The methods were developed on two platforms, an Orbitrap-based Thermo Exactive and a Q-IMS-TOF-based Waters Synapt G2S, where similar ion behaviors under optimized conditions were observed. Overall, our results suggested that within the working range (~1-10 MUM), gas phase ions in the native state linearly correspond to solution concentration and relative ion intensities of the apo- and holo-protein ions can linearly respond to the solution ratios, suggesting native MS is a viable tool for relative quantitation in this system. Graphical Abstract ?. PMID- 27709512 TI - Neural correlates of immediate and prolonged effects of cognitive reappraisal and distraction on emotional experience. AB - Cognitive emotion regulation strategies are important components of cognitive behavioral therapy (CBT). Additionally, up-regulation and difficulties in the down-regulation of negative feelings are associated with mental disorders. However, little is known about the lasting effects of cognitive emotion regulation strategies on emotional experience and associated neural activation. Therefore, this study investigated immediate and prolonged effects of emotion regulation using cognitive reappraisal and distraction on subjective report and its neural correlates. Twenty-seven healthy females took part in a 2-day functional magnetic resonance imaging study. They were instructed to either up regulate or down-regulate their negative feelings using a situation-focused cognitive reappraisal strategy, to distract themselves by imagining a specific neutral situation, or to passively look at repeatedly presented aversive and neutral pictures. Re-exposure to the same stimuli without a regulation instruction was conducted one day later. Self-reported negative feelings and blood-oxygen-level-dependent responses served as main outcome variables. As expected, the results show successful immediate up- or down-regulation of negative feelings by cognitive reappraisal and down-regulation of negative feelings by distraction. Furthermore, these changes in negative feelings were correlated with amygdala activation. A lasting effect on emotional experience associated with stronger ventromedial prefrontal cortex activation was found for down-regulation of negative feelings via cognitive reappraisal. Compared to distraction, down-regulation via cognitive reappraisal led to reduced negative feelings and stronger dorso- and ventrolateral prefrontal cortex responses one day later. While cognitive reappraisal and distraction are both effective strategies during active regulation, only cognitive reappraisal had a lasting effect. These findings might have implications for CBT.

AB - Cognitive reserve (CR) shows protective effects in Alzheimer's disease (AD) and reduces the risk of dementia. Despite the clinical significance of CR, a clinically useful diagnostic biomarker of brain changes underlying CR in AD is not available yet. Our aim was to develop a fully-automated approach applied to fMRI to produce a biomarker associated with CR in subjects at increased risk of AD. We computed resting-state global functional connectivity (GFC), i.e. the average connectivity strength, for each voxel within the cognitive control network, which may sustain CR due to its central role in higher cognitive function. In a training sample including 43 mild cognitive impairment (MCI) subjects and 24 healthy controls (HC), we found that MCI subjects with high CR (> median of years of education, CR+) showed increased frequency of high GFC values compared to MCI-CR- and HC. A summary index capturing such a surplus frequency of high GFC was computed (called GFC reserve (GFC-R) index). GFC-R discriminated MCI CR+ vs. MCI-CR-, with the area under the ROC = 0.84. Cross-validation in an independently recruited test sample of 23 MCI subjects showed that higher levels of the GFC-R index predicted higher years of education and an alternative questionnaire-based proxy of CR, controlled for memory performance, gray matter of the cognitive control network, white matter hyperintensities, age, and gender. In conclusion, the GFC-R index that captures GFC changes within the cognitive control network provides a biomarker candidate of functional brain changes of CR in patients at increased risk of AD.

AB - This study was performed to determine the effects of various doses of succinylcholine on resting tension and evoked twitch height at the masseter and adductor pollicis muscles in children. Twenty patients, aged 3-10yr, ASA physical status I or II, were randomly assigned to receive succinylcholine 0.15, 0.25, 0.50 or 1.00 mg . kg-1, during halothane-nitrous oxide anaesthesia. Supramaximal train-of-four stimulation was applied simultaneously to the ulnar nerve and the nerve to the masseter. Transducers recorded force at the jaw and the thumb. Maximum blockade of the first twitch (T1) and maximum resting tension change were measured. Potency of succinylcholine at the two muscles was estimated by linear regression of the logit transformation of T1 versus log dose. The relationship between resting tension change and log dose was established by linear regression. The masseter muscle was more sensitive to succinylcholine than the adductor pollicis with an ED95 of 0.28 +/- 0.02 (mean +/-SEM) vs 0.44 +/- 0.05 mg . kg-1 (P < 0.05). Onset of neuromuscular blockade was faster at the masseter, and recovery occurred simultaneously in both muscles. A dose-related increase in resting tension was observed in both muscles, but its magnitude was five times greater at the masseter. With succinylcholine, 1 mg . kg-1, this increase was 51.6 +/- 16.8 g at the masseter and 9.1 +/- 2.3 g at the adductor pollicis. Tension returned to baseline within 1-2 min. It is concluded that in children (1) succinylcholine produces dose-related changes in resting tension; (2) this effect, although quantitatively important at the masseter, is not restricted to that muscle; and (3) relatively small doses of succinylcholine are required to block neuromuscular transmission at the jaw. PMID- 27709522 TI - Adult pulmonary tuberculosis as a pathological manifestation of hyperactive antimycobacterial immune response. AB - The intricate relationship between tuberculosis (TB) and immune system remains poorly understood. It is generally believed that weakening of the immune response against Mycobacterium tuberculosis leads to reactivation of latent infection into the active pulmonary disease. However, heterogeneous nature of TB and failure of rationally designed vaccines in clinical trials raises serious questions against the simplistic view of TB as an outcome of weakened immunity. In the wake of accumulating human TB data, it is argued here that a hyperactive antimycobacterial immune response is to blame for the pathogenesis of pulmonary TB in immunocompetent adults. Direct and indirect evidence supporting this notion is presented in this article. Revisiting the role of immune system in TB pathogenesis will pave the way for effective anti-TB vaccines. PMID- 27709523 TI - Serum levels of S100A6 are unaltered in patients with resectable cholangiocarcinoma. AB - BACKGROUND: Elevated expression levels of S100A6, a calcium-binding low-molecular weight protein, were demonstrated in various malignancies. Moreover, increased serum levels of S100A6 were suggested as a novel biomarker for various inflammatory and malignant diseases including lung and gastric cancer. However, up to now, serum concentrations of S100A6 have not been analyzed in patients with cholangiocarcinoma (CCA). METHODS: S100A6 mRNA expression levels were analyzed in human and murine CCA tumor samples, using semi-quantitative reverse transcriptase PCR. S100A6 serum concentrations were measured using an enzyme-linked immunosorbent assay in 112 patients with CCA referred to surgery for curative resection and were compared to those of 42 healthy controls. Results were correlated with clinical data. RESULTS: S100A6 mRNA expression levels were significantly up-regulated in tumor samples of CCA patients and in tumor tissue of a CCA mouse model. In contrast, serum levels of S100A6 were not significantly altered in patients with CCA compared to healthy controls. Whereas no differences became apparent within the different clinical subgroups of CCA, patients with primary sclerosing cholangitis (PSC)-based CCA displayed higher levels of S100A6 compared to the other patients. Nevertheless, patients with higher S100A6 serum concentrations showed a trend towards an impaired prognosis compared to patients with lower levels. Finally, within our cohort of patients both the diagnostic and prognostic potentials of S100A6 were similar to those of the clinically established biomarkers CEA and CA19-9. CONCLUSION: Although S100A6 was expressed at significantly higher levels in human and murine CCA tumor samples, S100A6 serum levels were not regulated in patients with CCA and are thus not suitable for diagnosis of CCA. However, CCA-patients with elevated S100A6 displayed a trend toward an impaired prognosis compared to patients with lower S100A6 levels, supporting its further evaluation as a prognostic biomarker in CCA. PMID- 27709530 TI - Jaw muscle tension after succinychloline in children undergoing strabismus surgery. AB - The increases in tension at the masseter and adductor pollicis muscles following succinylcholine, 1 mg . kg-1, during halothane anaesthesia were measured in eight children, 3-10 yr, with strabismus. The results were compared with those obtained in a control group of general surgical patients. Supramaximal train-of-four (TOF) stimulation was applied to the ulnar nerve and the nerve to the masseter simultaneously. Jaw closure was measured by a force transducer system. In all patients, succinylcholine caused an increase in resting tone at the jaw and at the thumb. In the strabismus group, the magnitude of this increase was 55.7 +/ 23.2 g, mean +/-SD, at the jaw and 11.3 +/-5.6 g at the thumb. This was not significantly different from the values obtained in controls, 45.3 +/-33.4 g and 7.9 +/-4.2 g, respectively. The duration of the phenomenon was 1-2 min in both muscles studied, and was not statistically different in the strabismus group. Time to complete neuromuscular blockade was significantly faster at the masseter, 31 +/-6 sec -control groups; 39 +/-11 sec -strabismus group, than at adductor pollicis, 61 +/-34 sec -control groups; 75 +/-28 sec -strabismus group (P < 0.05 and 0.013 respectively). It is concluded that succinylcholine causes similar increases in jaw tension and comparable degrees of neuromuscular blockade in patients undergoing strabismus surgery as in other children.

AB - Au cours de 18 coelioscopies chez des jeunes femmes A.S.A. status physique 1, les consequences hemodynamiques du pneumoperitoine et de la position de Trendelenburg ont ete evaluees par la methode non invasive de bioimpedance electrique thoracique. L'index cardiaque chute significativement de 3,2 a 2,8 L . min-1 . m 2 a l'insufflation intra-abdominale et retrouve ses valeurs de depart apres dix minutes de Trendelenburg. La pression arterielle moyenne et les resistances vasculaires systemiques indexees sont tres augmentees de 1620 a 2491 dyn . s . cm 5 . m-2 apres insufflation; l'exsufflation ne permet pas un retour aux valeurs de depart: l'elevation residuelle des RVSI est de 30 pour cent. L'obstacle au retour veineux pas compression intra-abdominale explique bien la chute du debit cardiaque, conformement aux donnees de la litterature. En revanche, l'augmentation des resistances vasculaires systemiques ne peut etre expliquee par les seuls phenomenes mecaniques du fait de leur persistance apres la levee de la compression. L'hypothese de l'intervention d'un mediateur humoral doit done etre discutee.In 18 women A.S.A. physical status 1, a noninvasive thoracic electrical bioimpedance method was used to evaluate haemodynamic changes during gynaecologycal laparoscopy. A significant decrease in cardiac index was observed after peritoneal insufflation, from 3.2 to 2.8 L . min-1 . m-2 and returned to the initial values after ten minutes of Trendelenburg's position. Elevated intra abdominal pressure was also associated with a significant increase in mean arterial pressure (from 68 to 88 mmHg) and systemic vascular resistance index (from 1620 to 2491 dyn . s . cm-5 . m-2). However, values were not restored after peritoneal exsufflation: systemic vascular resistance index values remained 30 per cent higher than that before insufflation. Decreased venous return may account for the significant decrease in cardiac output but mechanical compression does not explain the persistent elevation of systemic vascular resistance. PMID- 27709533 TI - Advances in oral anti arrhythmic therapy: implications for the anaesthetist. AB - Surgical patients often are receiving antiarrhythmic therapy. Thus, because anaesthetic agents can affect cardiac function and may interact with concurrent antiarrhythmic medications, the anaesthetist should be aware of the electrophysiology associated with dysrhythmias and their management. Tocainide, flecainide, mexiletine, encainide and amiodarone have been introduced recently and each has an unique pattern of bioavailability, metabolism and toxicity. Patients treated with these drugs need special concern as they have abnormal cardiovascular systems and may be at increased risk for perioperative morbidity. In addition, unexpected untoward reactions and toxicity can result from interactions of anaesthetic agents and these drugs. This review discusses normal cardiac electrophysiology, common dysrhythmias and the electrophysiological effects of the newer oral antiarrhythmic drugs. PMID- 27709532 TI - Esmolol bolus and infusion attenuates increases in blood pressure and heart rate during electro-convulsive therapy. AB - To determine whether a standardized dose of esmolol can effectively attenuate the cardiovascular response to electroconvulsive therapy (ECT), 17 ASA physical status I-II patients were studied in a randomized within-patient, crossover design. Each patient received "no esmolol" during one ECT and three to five days later crossed over to the alternative treatment receiving an esmolol 80 mg bolus followed by 24 mg . min-1 infusion two minutes prior to induction of anaesthesia and continued for five minutes after induction. Esmolol blunted the maximum increases in heart rate (HR) by 26 per cent, mean arterial pressure (MAP) by 14 per cent, and rate pressure product by 37 per cent with significant differences (P < 0.05) noted at one, two, three and four minutes after ECT (minutes five, six, seven, and eight of the esmolol infusion). There was no significant difference in seizure duration between the two groups and no adverse reactions occurred.

Round table discussion on the methods and indications for determining blood levels of aminoglycosides]. AB - The present-day technique of determining the concentration of aminoglycosides in blood by agar diffusion is described including the apparatuses, set-up, and reliability tests. The results of comparative investigations showed a higher degree of conformity in Mueller-Hinton agar than in standard agar. Due to its accuracy the agar diffusion method is especially suited for the calculation of dosage recommendations and for the prediction of the maximal and minimal blood levels during treatment with aminoglycosides. PMID- 27709537 TI - Impact of preprocedural atrial fibrillation on immediate and long-term outcomes after successful percutaneous mitral valvuloplasty of significant mitral stenosis. AB - Optimal time to perform percutaneous mitral valvuloplasty (PMV) for patients with significant mitral stenosis (MS) and atrial fibrillation (AF) remains controversial. We sought to identify prognostic factors and evaluate long-term clinical outcomes after PMV of 77 consecutive patients with MS with a mitral valve area (MVA) <1.5 cm2. According to baseline heart rhythm, these patients were divided into sinus rhythm (SR; n = 24) and AF (n = 53) groups. The study endpoint was defined as a composite of all-cause mortality, admission for heart failure, mitral valve surgery, repeated PMV, and major cerebral vascular accident during follow-up. After successful PMV, there was no significant difference between the two groups in post-MVA and post-mitral mean pressure gradient. However, the New York Heart Association Functional Classification post-procedure was worse in the AF group (p < 0.01). In the AF group, event-free survival during follow-up was significantly lower compared with that of the SR group (p = 0.016). Independent predictors of clinical events were AF [hazard ratio (HR), 2.73; 95 % confidence interval (CI), 1.04-9.36; p = 0.03] and pulmonary artery systolic pressure (HR 2.57; 95 % CI 1.18-5.47; p = 0.017). Patients with AF at baseline were significantly associated with worse symptoms and higher event rates after successful PMV compared with those with SR. The clinical benefit of PMV may be considered for patients with MVA <1.5 cm2 before the onset of AF. PMID- 27709540 TI - [Microbiological diagnosis of septicemia]. AB - To detect microorganisms in the blood it is necessary not only that the microbiologist uses reliable methods, but also that the clinician takes a sufficient number of blood samples at the right point in time using a correct method for drawing the blood. The best results are obtained if the blood sample is transferred to the culture media at the bedside. The media should contain anticoagulants, osmosis stabilizers and preparations to neutralize the microbial action of the blood (caused by intrinsic and extrinsic factors). Up until now sodium polyanetholsulfonate ("Liquoid") has proved to be the most suitable additive. The procedure used for blood culturing must enable growth of aerobes, anaerobes and microbes with cell-wall damage. Today, modern methods such as radiometry, impedance measurement and microcalorimetry are used or are in the process of being developed which facilitate screening for positive cultures. Antigens, cell-wall constituents and metabolites of bacteria and fungi present in the blood stream can be detected by means of counter-immunoelectrophoresis, the Limulus test and gas chromatography, without culturing being necessary. Concentration techniques such as filtration and centrifugation are also being refined to enable a more reliable and earlier detection of septicemia. PMID- 27709544 TI - Evaluation and Elucidation Studies of Natural Aglycones for Anticancer Potential using Apoptosis-Related Markers: An In silico Study. AB - Exposure to exogenous and endogenous chemicals and subsequent cellular and molecular changes has been linked to enhanced cell proliferation and restricted apoptosis phenomenon. Though in the past decades numerous anticancer drugs inducing programmed cell death in cancer cells by targeting specific apoptotic markers have reached the market, they have been allied with unwanted side effects, ranging from mild to severe toxicity. With further understanding on the functional mechanism of p53 and MDM2 in apoptosis and in our continuous search for new and potent multi-target anticancer lead compounds, we have carried out molecular docking and inhibition studies of the selected aglycones along with selected anticancer leads, against the specific apoptotic and cell cycle markers using AutoDock Tools 4.0 and other computational softwares. The docking results have been analyzed in terms of binding energies (kcal/mol) and inhibition constant (uM). The study clearly proposes our aglycones [solanidine (Solanid-5-en 3beta-ol), solasodine (Solasod-5-en-3beta-ol), and tomatidine (5alpha-Tomatidan 3beta-ol)] induce apoptosis by inhibiting the p53-MDM2 complex, p21Waf1/Cip1, and Bcl-2 proteins, which were even found comparable with the anticancer drugs nutlin and/or halofuginone. The work further emphasizes that the individual molecular targets such as BAX and Bcl-2 may result in misleading data at any level; however, ratio of responses to BAX and Bcl-2 shall be considered for better clue about a compound to be pro- or anti-apoptotic.

AB - We report on two patients with acute leukemia and prolonged granulocytopenia after cytotoxic therapy in whom the diagnosis hepatosplenic candidiasis was made. Both patients developed upper abdominal discomfort with elevated alkaline phosphatase after resolution of granulocytopenia. The diagnosis was established by demonstration of multiple abscesses in liver and spleen on ultrasound and computed tomography. Both patients were initially treated with amphotericin B i.v., one of them received liposomal amphotericin B (cumulative dose of 2,530 mg and 570 mg, respectively). Thereafter, therapy was continued for months with oral fluconazole. The treatment of hepatosplenic candidiasis was successful, however, the patients died from relapse and progression of leukemia. PMID- 27709547 TI - Rapid total volatile organic carbon quantification from microbial fermentation using a platinum catalyst and proton transfer reaction-mass spectrometry. AB - A novel analytical system was developed to rapidly and accurately quantify total volatile organic compound (VOC) production from microbial reactor systems using a platinum catalyst and a sensitive CO2 detector. This system allows nearly instantaneous determination of total VOC production by utilizing a platinum catalyst to completely and quantitatively oxidize headspace VOCs to CO2 in coordination with a CO2 detector. Measurement of respiratory CO2 by bypassing the catalyst allowed the total VOC content to be determined from the difference in the two signals. To the best of our knowledge, this is the first instance of a platinum catalyst and CO2 detector being used to quantify the total VOCs produced by a complex bioreactor system. Continuous recording of these CO2 data provided a record of respiration and total VOC production throughout the experiments. Proton transfer reaction-mass spectrometry (PTR-MS) was used to identify and quantify major VOCs. The sum of the individual compounds measured by PTR-MS can be compared to the total VOCs quantified by the platinum catalyst to identify potential differences in detection, identification and calibration. PTR-MS measurements accounted on average for 94 % of the total VOC carbon detected by the platinum catalyst and CO2 detector. In a model system, a VOC producing endophytic fungus Nodulisporium isolate TI-13 was grown in a solid state reactor utilizing the agricultural byproduct beet pulp as a substrate. Temporal changes in production of major volatile compounds (ethanol, methanol, acetaldehyde, terpenes, and terpenoids) were quantified by PTR-MS and compared to the total VOC measurements taken with the platinum catalyst and CO2 detector. This analytical system provided fast, consistent data for evaluating VOC production in the nonhomogeneous solid state reactor system. PMID- 27709546 TI - Phantom criteria for qualification of brain FDG and amyloid PET across different cameras. AB - BACKGROUND: While fluorodeoxyglucose (FDG) and amyloid PET is valuable for patient management, research, and clinical trial of therapeutics on Alzheimer's disease, the specific details of the PET scanning method including the PET camera model type influence the image quality, which may further affect the interpretation of images and quantitative capabilities. To make multicenter PET data reliable and to establish PET scanning as a universal diagnostic technique and a verified biomarker, we have proposed phantom test procedures and criteria for optimizing image quality across different PET cameras. RESULTS: As the method, four physical parameters (resolution, gray-white contrast, uniformity, and image noise) were selected as essential to image quality for brain FDG and amyloid PET and were measured with a Hoffman 3D brain phantom and a uniform cylindrical phantom on a total of 12 currently used PET models. The phantom radioactivity and acquisition time were determined based on the standard scanning protocol for each PET drug (FDG, 11C-PiB, 18F-florbetapir, and 18F-flutemetamol). Reconstruction parameters were either determined based on the methods adopted in ADNI, J-ADNI, and other research and clinical trials or optimized based on measured phantom image parameters under various reconstruction conditions. As the result, phantom test criteria were proposed as follows: (i) 8 mm FWHM or better resolution and (ii) gray/white %contrast >=55 % with the Hoffman 3D brain phantom and (iii) SD of 51 small region of interests (ROIs) <=0.0249 (equivalent to 5 % variation) for uniformity and (iv) image noise (SD/mean) <=15 % for a large ROI with the uniform cylindrical phantom. These criteria provided image quality conforming to those multicenter clinical studies and were also achievable with most of the PET cameras that are currently used. CONCLUSIONS: The proposed phantom test criteria facilitate standardization and qualification of brain FDG and amyloid PET images and deserve further evaluation by future multicenter clinical studies. PMID- 27709548 TI - Cancer/testis antigens as molecular drug targets using network pharmacology. AB - Present chemotherapeutic drugs have limited efficacy and severe side effects. Considering the complexity of cancer, an effective strategy is necessary to discover multiple new drug targets. Cancer/testis antigens are vital for cancer cell progression. We have performed a computational network analysis of cancer/testis antigens and assessed these antigens as drug targets. During this analysis, protein interaction network of 700 human CT antigens was investigated. CT antigen network consisted of eight independent components. Four major hubs and two minor hubs were identified that play nodal role in the flow of information across the largest network. We have predicted 30 potential drug targets by analysing several topological parameters such as betweenness centrality, cluster coefficient and probable protein complexes. Structural and functional roles of potential drug targets have also been anatomized. Analysis of the CT antigen network enables us to pinpoint a set of candidate proteins that if targeted could be detrimental for cancerous cell without affecting any normal cell. The list of putative proteins is a starting point for experimental validation and may help further in the discovery of new anticancer drug targets. PMID- 27709549 TI - Reversal effect of ouabain on multidrug resistance in esophageal carcinoma EC109/CDDP cells by inhibiting the translocation of Wnt/beta-catenin into the nucleus. AB - The incidence of esophageal carcinoma is increasing throughout the world. A major obstacle to its treatment is acquired multidrug resistance (MDR) which results in the failure of chemotherapy and patient relapse. Here, we identified that ouabain is capable of reversing MDR to cisplatin (CDDP) in EC109/CDDP cells and explore the possible mechanisms of action. The parental and the MDR cell lines were both sensitive to ouabain with 50 % inhibitory concentration (IC50) values of 258.11 and 710.63 nM, respectively. Cisplatin cytotoxicity increased in the EC109/CDDP cells by the addition of ouabain which helps promote CDDP-induced apoptosis. Ouabain at 20 nM effectively reduced the IC50 of CDDP in EC109/CDDP cells from 36.54 to 3.39 MUM. This represents a 10.78-fold increase in sensitization to CDDP. We also found that ouabain was capable of down regulating the expression of P-glycoprotein (P-gp) and Bcl-2 in a dose- and time-dependent manner. Finally, the results indicated that ouabain suppressed Wnt luciferase report (TOPFlash) activity obviously in EC109/CDDP and depressed the translocation of beta-catenin into the nucleus. Moreover, ouabain showed reversal effect of MDR to CDDP in nude mouse xenograft model, and reduced the protein level of beta-catenin (Y333) in tumor tissue of CDDP plus ouabain group. All data proved that ouabain has a potent beta-catenin-dependent anti-MDR effect. PMID- 27709550 TI - CD4+ T cell-mediated cytotoxicity eliminates primary tumor cells in metastatic melanoma through high MHC class II expression and can be enhanced by inhibitory receptor blockade. AB - Metastatic melanoma is a rapidly progressing disease with high mortality rate and limited treatment options. Immunotherapy based on tumor-targeting cytotoxic T cell responses represents a promising strategy. To assist in its development, we examined the possibility and efficacy of using CD4+ cytotoxic T cells. The regulatory mechanisms controlling CD4+ T cell-mediated cytotoxicity were also investigated. We found that naturally occurring granzyme B and perforin expressing CD4+ cytotoxic T cells can be recovered from metastatic melanoma patients at significantly elevated frequencies compared to those from healthy controls. These CD4+ cytotoxic T cells were also capable of killing autologous tumor cells harvested from metastatic melanoma, independent of CD8+ T cells or any other cell types. However, several restricting factors were observed. First, the cytolytic activity by CD4+ T cells required high MHC class II expression on melanoma cells, which was not satisfied in a subset of melanomas. Second, the granzyme B and perforin release by activated CD4+ cytotoxic T cells was reduced after coculturing with autologous melanoma cells, characterized by low LAMP-1 expression and low granzyme B and perforin secretion in the supernatant. This suggested that inhibitory mechanisms were present to suppress CD4+ cytotoxic T cells. Indeed, blockade of PD-1 and CTLA-4 had increased the cytolytic activity of CD4+ T cells but was only effective in MHC class II high but not MHC class II low melanomas. Together, our study showed that CD4+ T cell-mediated cytotoxicity could eliminate primary melanoma cells but the efficacy depended on MHC class II expression. PMID- 27709551 TI - Serum levels of apolipoprotein E correlates with disease progression and poor prognosis in breast cancer. AB - ApoE has been reported to be associated with tumorigenesis and tumor progression. In this study, we explored the potential diagnostic and prognostic role of serum ApoE in breast cancer patients. Subject cohorts consisted of 152 normal healthy controls female and 257 breast cancer cases. Serum levels of ApoE were determined with turbidimetric immunoassay. The serum levels of ApoE were significantly elevated in breast cancer patients compared with normal healthy controls (45.82 +/- 13.96 mg/L vs. 33.61 +/- 6.44 mg/L, respectively, P < 0.0001) and also significantly associated with TNM stage and lymph nodes status (all P < 0.05). Area under receiver operating characteristic curve for serum ApoE discriminate breast cancer patients from controls was 0.786 with specificity of 0.974 and sensitivity of 0.541, the cut-off value of ApoE was 43.15 mg/L. Kaplan-Meier log rank analysis showed that the high serum ApoE group (serum ApoE >= 43.15 mg/L) had a poorer progression-free survival and overall survival compared with low serum ApoE group (serum ApoE < 43.15 mg/L) (all P < 0.05). In addition, univariate and multivariate Cox regression analysis displayed serum ApoE as an independent risk factor of breast cancer patients prognosis (all P < 0.05). Serum ApoE played a role as serological biomarkers that indicated diagnostic and prognostic evaluation in breast cancer patients. PMID- 27709552 TI - A new ten-gene risk fraction model serving as prognostic indicator for clinical outcome of multiple myeloma. AB - Multiple myeloma (MM) is a kind of aggressive tumor prevalent with high heterogeneity. Abnormal expression of certain genes may lead to the occurrence and development of MM. Nowadays, it is not commonly seen in clinical research to predict the prognostic circumstances of patients with MM by multiple gene expression profiling method. Identification of potential genes in prognostic process could be beneficial for clinical management of MM. Therefore, we aimed to build a risk fraction model to screen out the prognostic indicator for clinical outcome of MM. Microarray data were downloaded from the Genome Expression Omnibus (GEO) datasets with accession numbers GSE24080 and GSE57317. A total of 279 samples were selected out randomly. Besides, a risk formula was constructed and verified in the dataset. Time-dependent receiver operating characteristic (ROC) curve was applied in evaluating the accurate prognostic conditions of patients. Finally, a ten genes model in the training dataset was found to be closely related to the survival condition of MM patients. Patients with MM were divided into two groups, high-risk and low-risk, by the expression of these ten genes, and significant statistical difference was found between the two groups. Furthermore, the result of multivariate cox regression and stratified analysis indicated that this model was independent of other clinical phenotypes. ROC curves also showed its feasibility to predict the survival status of MM patients. Our results demonstrated that the fraction risk model constructed by the selected ten genes could be used to predict survival status of multiple myeloma patients, which could also help in improvement of prognostic and therapeutic tool of MM. PMID- 27709553 TI - Long noncoding RNA expression profile of infantile hemangioma identified by microarray analysis. AB - Infantile hemangioma (IH) is one of the most common vascular tumors of childhood. Long noncoding RNAs (lncRNAs) play a critical role in angiogenesis, but their involvement in hemangioma remains unknown. This study aimed to assess the expression profiles of lncRNAs in IH and adjacent normal tissue samples, exploring the biological functions of lncRNAs as well as their involvement in IH pathogenesis. The lncRNA expression profiles were determined by lncRNA microarrays. A total of 1259 and 857 lncRNAs were upregulated and downregulated in IH, respectively, at a fold change cutoff of 2.0 (p < 0.05); in addition, 1469 and 1184 messenger RNAs (mRNAs) were upregulated and downregulated, respectively (fold change cutoff of 2.0; p < 0.05). A total of 292 differentially expressed mRNAs were targeted by the lncRNAs with altered expression in hemangioma, including 228 and 64 upregulated and downregulated, respectively (cutoff of 2.0, p < 0.05). Gene ontology (GO) analyses revealed several angiogenesis-related pathways. An lncRNA-mRNA co-expression network for differentially expressed lncRNAs revealed significant associations of the lncRNAs MEG3, MEG8, FENDRR, and Linc00152 with their related mRNAs. The validation results of nine differentially expressed lncRNAs (MALAT1, MEG3, MEG8, p29066, p33867, FENDRR, Linc00152, p44557_v4, p8683) as well as two mRNAs (FOXF1, EGFL7) indicated that the microarray data correlated well with the QPCR results. Interestingly, MALAT1 knockdown induced apoptosis and S-phase cell cycle arrest in human umbilical vein endothelial cells (HUVECs). Overall, this study revealed the lncRNA expression profile of IH and that lncRNAs likely regulate several genes with important roles in angiogenesis. PMID- 27709554 TI - The Role of Ultrasound on Advanced Oxidation Processes. AB - This chapter describes the use of ultrasound in remediation of wastewater contaminated with organic pollutants in the absence and presence of other advanced oxidation processes (AOPs) such as sonolysis, sono-ozone process, sonophotocatalysis, sonoFenton systems and sonophoto-Fenton methods in detail. All these methods are explained with the suitable literature illustrations. In most of the cases, hybrid AOPs (combination of ultrasound with one or more AOPs) resulted in superior efficacy to that of individual AOP. The advantageous effects such as additive and synergistic effects obtained by operating the hybrid AOPs are highlighted with appropriate examples. It is worth to mention here that the utilization of ultrasound is not only restricted in preparation of modern active catalysts but also extensively used for the wastewater treatment. Interestingly, ultrasound coupled AOPs are operationally simple, efficient, and environmentally benign, and can be readily applied for large scale industrial processes which make them economically viable. PMID- 27709556 TI - Prognosis of cirrhotic patients admitted to the general ICU. AB - BACKGROUND: The prognosis of cirrhotic patients admitted to the ICU is considered to be poor but has been mainly reported in liver ICU. We aimed to describe the prognosis of cirrhotic patients admitted to a general ICU, to assess the predictors of mortality in this population, and, finally, to identify a subgroup of patients in whom intensive care escalation might be discussed. RESULTS: We performed a retrospective monocentric study of all cirrhotic patients consecutively admitted between 2002 and 2014 in a general ICU in a regional university hospital. Two hundred and eighteen cirrhotic patients were admitted to the ICU. The 28-day and 6-month mortality rates were 53 and 74 %, respectively. Among the 115 patients who were discharged from ICU, only eight patients underwent liver transplantation, whereas 48 had no clear contraindication. Multivariable analyses on 28-day mortality identified three independent variables, incorporated into a new three-variable prognostic model as follows: SOFA >= 12 (OR 4.2 [2.2-8.0]; 2 points), INR >= 2.6 (OR 2.5 [1.3-4.8]; 1 point), and renal replacement therapy (OR 2.3 [1.1-5.1]; 1 point). For a value of the score at 4 (16 % of patients), 28-day and 3-month mortality rates were 91 and 100 %, respectively. An external validation of the score among 149 critically ill cirrhotic patients showed a good accuracy for predicting in-ICU mortality. CONCLUSIONS: Mortality of cirrhotic patients admitted to a general ICU was comparable to that of other studies. A pragmatic score integrating the SOFA score, INR, and the need for extrarenal epuration was strongly associated with mortality. Among the 16 % of patients presenting with score 4 at ICU admission, 100 % died in the 3-month follow-up period. The prognostic evaluation on day 3 remains essential for the majority of patients. However, this score calculable at ICU admission might identify patients in whom the benefit of intensive care escalation should be discussed, in particular when liver transplantation is contraindicated. PMID- 27709555 TI - Post-Concussive Syndrome: a Focus on Post-Traumatic Headache and Related Cognitive, Psychiatric, and Sleep Issues. AB - PURPOSE OF REVIEW: Post-traumatic headache (PTH) is a secondary headache disorder following traumatic brain injury. We sought to examine the recent literature on PTH and associated cognitive, psychiatric, and sleep conditions to understand the latest findings about the associated conditions and available screening tools, and to understand the available treatment options for PTH. RECENT FINDINGS: Up to one third of PTH patients may have depression and about one quarter may have insomnia. Anxiety and cognitive issues are also common. While there are few studies examining abortive medications for PTH, recent studies of preventive medications examine the efficacy of topiramate, and topiramate may be better than other oral preventive medications. Other currently investigated treatments include nerve blocks, onabotulinum toxin A, transmagnetic stimulation, and behavioral therapy (biofeedback). Due to an expanded focus on and knowledge of concussion and PTH, comorbid psychiatric, cognitive, and sleep issues have become more widely acknowledged and studied. However, more high-quality studies must be conducted to examine the underlying pathophysiology of PTH and associated symptoms and to determine the most effective abortive and preventive treatment options. PMID- 27709557 TI - Erythrocyte superoxide dismutase as a biomarker of septic acute kidney injury. AB - BACKGROUND: Oxidative stress is a key feature of sepsis and could be a common pathophysiological pathway between septic shock and acute kidney injury (AKI) Our objective was to evaluate the erythrocyte superoxide dismutase (SOD1) activity as predictor of AKI in patients with septic shock. METHODS: This is a prospective observational study that evaluated 175 consecutive patients over the age of 18 years with septic shock upon intensive care unit (ICU) admission. However, 43 patients were excluded (27 due to AKI at ICU admission). Thus, 132 patients were enrolled in the study. At the time of the patients' enrollment, demographic information was recorded. Blood samples were taken within the first 24 h of the patient's admission to determine the erythrocyte SOD1 activity. All patients were followed throughout the ICU stay, and the development of AKI was evaluated. In addition, we also evaluated 17 control subjects. RESULTS: The mean age of patients with septic shock was 63.2 +/- 15.7 years, 53 % were male and the median ICU stay was 8 days (4-16). Approximately 50.7 % developed AKI during the ICU stay. The median erythrocyte SOD1 activity was 2.92 (2.19-3.92) U/mg Hb. When compared to control subjects, septic shock patients had a higher serum malondialdehyde concentration and lower erythrocyte SOD1 activity. In univariate analysis, erythrocyte SOD1 activity was lower in patients who developed AKI. The ROC curve analysis revealed that lower erythrocyte SOD1 activity was associated with AKI development (AUC 0.686; CI 95 % 0.595-0.777; p < 0.001) at the cutoff of <3.32 U/mg Hb. In the logistic regression models, SOD1 activity higher than 3.32 U/mg Hb was associated with protection of AKI development when adjusted by hemoglobin, phosphorus and APACHE II score (OR 0.309; CI 95 % 0.137-0.695; p = 0.005) and when adjusted by age, gender, chronic kidney disease, admission category (medical or surgery) and APACHE II score (OR 0.129; CI 95 % 0.033-0.508; p = 0.003). CONCLUSIONS: In conclusion, our data suggest that erythrocyte SOD1 activity could play a role as an early marker of septic AKI and could be seen as a new research avenue in the field of biomarker in AKI. However, our study did not show a strong correlation between SOD activity and AKI. Nevertheless, these original data do warrant further research in order to confirm or not this hypothesis.

AB - Biocompatible silk fibroin (SF):poly(vinyl alcohol) (PVA) blends were prepared as the dielectric layers of organic field-effect transistors (OFETs). Compared with those with pure SF dielectric layer, an optimal threshold voltage of ~0 V, high on/off ratio of ~104, and enhanced field-effect mobility of 0.22 cm2/Vs of OFETs were obtained by carefully controlling the weight ratio of SF:PVA blends to 7:5. Through the morphology characterization of dielectrics and organic semiconductors by utilizing atom force microscopy and electrical characterization of the devices, the performance improvement of OFETs with SF:PVA hybrid gate dielectric layers were attributed to the smooth and homogeneous morphology of blend dielectrics. Furthermore, due to lower charge carrier trap density, the OFETs based on SF:PVA-blended dielectric exhibited a higher bias stability than those based on pure SF dielectric. PMID- 27709559 TI - Pulsed Laser Ablation-Induced Green Synthesis of TiO2 Nanoparticles and Application of Novel Small Angle X-Ray Scattering Technique for Nanoparticle Size and Size Distribution Analysis. AB - This paper aims to introduce small angle X-ray scattering (SAXS) as a promising technique for measuring size and size distribution of TiO2 nanoparticles. In this manuscript, pulsed laser ablation in liquids (PLAL) has been demonstrated as a quick and simple technique for synthesizing TiO2 nanoparticles directly into deionized water as a suspension from titanium targets. Spherical TiO2 nanoparticles with diameters in the range 4-35 nm were observed with transmission electron microscopy (TEM). X-ray diffraction (XRD) showed highly crystalline nanoparticles that comprised of two main photoactive phases of TiO2: anatase and rutile. However, presence of minor amounts of brookite was also reported. The traditional methods for nanoparticle size and size distribution analysis such as electron microscopy-based methods are time-consuming. In this study, we have proposed and validated SAXS as a promising method for characterization of laser ablated TiO2 nanoparticles for their size and size distribution by comparing SAXS and TEM-measured nanoparticle size and size distribution. SAXS- and TEM-measured size distributions closely followed each other for each sample, and size distributions in both showed maxima at the same nanoparticle size. The SAXS measured nanoparticle diameters were slightly larger than the respective diameters measured by TEM. This was because SAXS measures an agglomerate consisting of several particles as one big particle which slightly increased the mean diameter. TEM- and SAXS-measured mean diameters when plotted together showed similar trend in the variation in the size as the laser power was changed which along with extremely similar size distributions for TEM and SAXS validated the application of SAXS for size distribution measurement of the synthesized TiO2 nanoparticles. PMID- 27709558 TI - DNA copy number alterations, gene expression changes and disease-free survival in patients with colorectal cancer: a 10 year follow-up. AB - BACKGROUND: DNA copy number alterations (CNAs) and gene expression changes have amply been encountered in colorectal cancers (CRCs), but the extent at which CNAs affect gene expression, as well as their relevance for tumor development, are still poorly defined. Here we aimed at assessing the clinical relevance of these parameters in a 10 year follow-up study. METHODS: Tumors and normal adjacent colon mucosa, obtained at primary surgery from 21 CRC patients, were subjected to (i) high-resolution array CGH (a-CGH) for the detection of CNAs and (ii) microarray-based transcriptome profiling for the detection of gene expression (GE) changes. Correlations between these genomic and transcriptomic changes and their associations with clinical and histopathological parameters were assessed with the aim to identify molecular signatures associated with disease-free survival of the CRC patients during a 10 year follow-up. RESULTS: DNA copy number gains were frequently detected in chromosomes 7, 8q, 13, 19, 20q and X, whereas DNA copy number losses were frequently detected in chromosomes 1p, 4, 8p, 15, 17p, 18, 19 and 22q. None of these alterations were observed in all samples. In addition, we found that 2,498 genes were up- and that 1,094 genes were down regulated in the tumor samples compared to their corresponding normal mucosa (p < 0.01). The expression of 65 genes was found to be significantly associated with prognosis (p < 0.01). Specifically, we found that up-regulation of the IL17RA, IGF2BP2 and ABCC2 genes, and of genes acting in the mTOR and cytokine receptor pathways, were strongly associated with a poor survival. Subsequent integrated analyses revealed that increased expression levels of the MMP9, BMP7, UBE2C, I CAM, NOTCH3, NOTCH1, PTGES2, HMGB1 and ERBB3 genes were associated with copy number gains, whereas decreased expression levels of the MUC1, E2F2, HRAS and SIRT3 genes were associated with copy number losses. Pathways related to cell cycle progression, eicosanoid metabolism, and TGF-beta and apoptosis signaling, were found to be most significantly affected. CONCLUSIONS: Our results suggest that CNAs in CRC tumor tissues are associated with concomitant changes in the expression of cancer-related genes. In other genes epigenetic mechanism may be at work. Up-regulation of the IL17RA, IGF2BP2 and ABCC2 genes, and of genes acting in the mTOR and cytokine receptor pathways, appear to be associated with a poor survival. These alterations may, in addition to Dukes' staging, be employed as new prognostic biomarkers for the prediction of clinical outcome in CRC patients. PMID- 27709561 TI - Highly Efficient Catalysis of Azo Dyes Using Recyclable Silver Nanoparticles Immobilized on Tannic Acid-Grafted Eggshell Membrane. AB - In this study, a facile one-step synthesis of a novel nanocomposite catalytic film was developed based on silver nanoparticles (AgNPs) immobilized in tannic acid-modified eggshell membrane (Tan-ESM). Tannic acid, as a typical plant polyphenol from oak wood, was first grafted onto ESM fibers to serve as both the reductant and the stabilizer during the synthesis of AgNPs. The morphology, constitution, and thermal stability of the resulting AgNPs@Tan-ESM composites were fully characterized to explain the excellent catalytic efficiency of AgNPs@Tan-ESM composites. These composite catalysts were applied to the degradation of azo dyes which exhibited the high catalytic activity toward Congo red and methyl orange according to the kinetic curves. More importantly, they can be easily recovered and reused for many times because of their good stability. PMID- 27709562 TI - Electrochemical Properties of Rutile TiO2 Nanorod Array in Lithium Hydroxide Solution. AB - In this paper, rutile TiO2 nanorod arrays are fabricated by a template-free method and proposed as a promising anode for aqueous Li-ion battery. The as prepared TiO2 nanorod arrays exhibited reversible Li-ion insertion/extraction ability in aqueous LiOH electrolyte. Moreover, galvanostatic charge/discharge test results demonstrated that the reversible capacity of TiO2 nanorods could reach about 39.7 mC cm-2, and 93.8 % of initial capacity was maintained after 600 cycles at a current density of 1 mA cm-2 (=240 C rate), indicating excellent cycling stability and rate capability. PMID- 27709563 TI - Potential Suppressive Effects of Two C60 Fullerene Derivatives on Acquired Immunity. AB - The therapeutic effects of fullerene derivatives on many models of inflammatory disease have been demonstrated. The anti-inflammatory mechanisms of these nanoparticles remain to be elucidated, though their beneficial roles in allergy and autoimmune diseases suggest their suppressive potential in acquired immunity. Here, we evaluated the effects of C60 pyrrolidine tris-acid (C60-P) and polyhydroxylated fullerene (C60(OH)36) on the acquired immune response in vitro and in vivo. In vitro, both C60 derivatives had dose-dependent suppressive effects on T cell receptor-mediated activation of T cells and antibody production by B cells under anti-CD40/IL-4 stimulation, similar to the actions of the antioxidant N-acetylcysteine. In addition, C60-P suppressed ovalbumin-specific antibody production and ovalbumin-specific T cell responses in vivo, although T cell-independent antibodies responses were not affected by C60-P. Together, our data suggest that fullerene derivatives can suppress acquired immune responses that require T cells. PMID- 27709564 TI - The Potential of Lactobacillus casei and Entercoccus faecium Combination as a Preventive Probiotic Against Entamoeba. AB - Travellers' diarrhoea caused by enteric protozoa like Entamoeba histolytica is among the most common protozoan diseases in developing countries. In developing countries, amoebiasis is the second most prevalent protozoan disease. This protozoan parasite is often known to coexist as a part of the normal gut microbiota. It is estimated that around 50-60 % of population in developing countries might be harbouring Entamoeba in an asymptomatic manner. Due to physiological perturbation or upon immuno-compromise, it can become virulent and then cause diarrhoea, bloody stools and may invade other organs if left untreated. Nitroimidazole drugs, namely metronidazole and tinidazole, are widely used to treat protozoan infections. These drugs often show dose-dependent side effects. With emerging antibiotic resistance, novel therapeutics to prevent parasitic infections is required. This study aims to study effect of probiotics on prevention of Amoebiasis. In this study, we have investigated the effect of selected probiotics on the growth of Entamoeba. From the list of probiotics being currently used, five bacterial strains were selected for testing. These probiotic strains were co-cultured with Entamoeba, and their effect on Entamoeba proliferation was checked. Of the five probiotics chosen, individual treatments of Lactobacillus casei and Enterococcus faecium showed a significant reduction of up to 71 % in parasite survival only at higher CFUs. When the two probiotics were used in combination, the percentage of survival reduced gradually further to 80 % at a total CFU of 109 cells/ml of bacteria. The study lays the foundation for providing cost-effective prophylactic treatment for amoebiasis without the overuse of antibiotics. PMID- 27709565 TI - Design and Validation of CRISPR/Cas9 Systems for Targeted Gene Modification in Induced Pluripotent Stem Cells. AB - The CRISPR/Cas9 system is a powerful tool for precision genome editing. The ability to accurately modify genomic DNA in situ with single nucleotide precision opens up new possibilities for not only basic research but also biotechnology applications and clinical translation. In this chapter, we outline the procedures for design, screening, and validation of CRISPR/Cas9 systems for targeted modification of coding sequences in the human genome and how to perform genome editing in induced pluripotent stem cells with high efficiency and specificity. PMID- 27709566 TI - Mutagenesis and Genome Engineering of Epstein-Barr Virus in Cultured Human Cells by CRISPR/Cas9. AB - The clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR associated protein 9 nuclease (Cas9) system is a powerful genome-editing tool for both chromosomal and extrachromosomal DNA. DNA viruses such as Epstein-Barr virus (EBV), which undergoes episomal replication in human cells, can be effectively edited by CRISPR/Cas9. We have demonstrated targeted editing of the EBV genome by CRISPR/Cas9 in several lines of EBV-infected cells. CRISPR/Cas9-based mutagenesis and genome engineering of EBV provides a new method for genetic analysis, which has some advantages over bacterial artificial chromosome-based recombineering. This approach might also prove useful in the cure of EBV infection. In this chapter, we use the knockout of the BART promoter as an example to detail the experimental procedures for construction of recombinant EBV in human cells. PMID- 27709567 TI - Use of CRISPR/Cas Genome Editing Technology for Targeted Mutagenesis in Rice. AB - Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/CRISPR associated protein (Cas) system is a newly emerging mutagenesis (gene-editing) tool in genetic engineering. Among the agriculturally important crops, several genes have been successfully mutated by the system, and some agronomic important traits have been rapidly generated, which indicates the potential applications in both scientific research and plant breeding. In this chapter, we describe a standard gene-editing procedure to effectively target rice genes and to make specific rice mutants using the CRISPR/Cas9 system mediated by Agrobacterium transformation. PMID- 27709568 TI - All-in-One CRISPR-Cas9/FokI-dCas9 Vector-Mediated Multiplex Genome Engineering in Cultured Cells. AB - CRISPR-Cas9 enables highly convenient multiplex genome engineering in cultured cells, because it utilizes generic Cas9 nuclease and an easily customizable single-guide RNA (sgRNA) for site-specific DNA double-strand break induction. We previously established a multiplex CRISPR-Cas9 assembly system for constructing an all-in-one vector simultaneously expressing multiple sgRNAs and Cas9 nuclease or other Cas9 variants including FokI-dCas9, which supersedes the wild-type Cas9 with regard to high specificity. In this chapter, we describe a streamlined protocol to design and construct multiplex CRISPR-Cas9 or FokI-dCas9 vectors, to introduce them into cultured cells by lipofection or electroporation, to enrich the genomically edited cells with a transient puromycin selection, to validate the mutation efficiency by Surveyor nuclease assay, and to perform off-target analyses. We show that our protocol enables highly efficient multiplex genome engineering even in hard-to-transfect HepG2 cells. PMID- 27709571 TI - Generation of Stable Knockout Mammalian Cells by TALEN-Mediated Locus-Specific Gene Editing. AB - Precise and targeted genome editing using Transcription Activator-Like Effector Endonucleases (TALENs) has been widely used and proven to be an extremely effective and specific knockout strategy in both cultured cells and animal models. The current chapter describes a protocol for the construction and generation of TALENs using serial and hierarchical digestion and ligation steps, and using the synthesized TALEN pairs to achieve locus-specific targeted gene editing in mammalian cell lines using a modified clonal selection strategy in an easy and cost-efficient manner. PMID- 27709569 TI - CRISPR/Cas9-Mediated Mutagenesis of Human Pluripotent Stem Cells in Defined Xeno Free E8 Medium. AB - The recent advent of engineered nucleases including the CRISPR/Cas9 system has greatly facilitated genome manipulation in human pluripotent stem cells (hPSCs). In addition to facilitating hPSC-based disease studies, the application of genome engineering in hPSCs has also opened up new avenues for cell replacement therapy. To improve consistency and reproducibility of hPSC-based studies, and to meet the safety and regulatory requirements for clinical translation, it is necessary to use a defined, xeno-free cell culture system. This chapter describes protocols for CRISPR/Cas9 genome editing in an inducible Cas9 hPSC-based system, using cells cultured in chemically defined, xeno-free E8 Medium on a recombinant human vitronectin substrate. We detail procedures for the design and transfection of CRISPR guide RNAs, colony selection, and the expansion and validation of clonal mutant lines, all within this fully defined culture condition. These methods may be applied to a wide range of genome-engineering applications in hPSCs, including those that utilize different types of site-specific nucleases such as zinc finger nucleases (ZFNs) and TALENs, and form a closer step towards clinical utility of these cells. PMID- 27709570 TI - Development of CRISPR/Cas9 for Efficient Genome Editing in Toxoplasma gondii. AB - Efficient and site-specific alteration of the genome is key to decoding and altering the genomic information of an organism. Over the last couple of years, the RNA-guided Cas9 nucleases derived from the prokaryotic type 2 CRISPR (clustered regularly interspaced short palindromic repeats) systems have drastically improved our ability to engineer the genomes of a variety of organisms including Toxoplasma gondii. In this chapter, we describe detailed protocols for using the CRISPR/Cas9 system adapted from Streptococcus pyogenes to perform efficient genetic manipulations in T. gondii such as gene disruption, gene tagging and genetic complementation. The technical details of the strategy, including CRISPR plasmid construction, target construct generation, parasite transfection and positive clone identification are also provided. These methods are easy to customize to any gene of interest (GOI) and will greatly accelerate studies on this important pathogen. PMID- 27709572 TI - Efficient Generation of Gene-Modified Mice by Haploid Embryonic Stem Cell Mediated Semi-cloned Technology. AB - Haploid embryonic stem cells can be derived from androgenetic embryos produced by injection of sperm into enucleated oocytes or by removal of the female pronucleus from zygotes. These cells, termed AG-haESCs, can be used in place of sperm to produce the so-called semi-cloned (SC) mice. Importantly, AG-haESCs carrying H19 DMR and IG-DMR knockouts (DKO-AG-haESCs) can efficiently and stably support the generation of SC mice via intracytoplasmic AG-haESCs injection (ICAHCI), which provides a new route to obtain genetically modified mice. In this chapter, we describe the procedures for AG-haESCs culturing, enrichment of haploid cells by FACS, genomic manipulation in DKO-AG-haESCs by CRISPR/Cas9 and generation of live SC mice with gene-modified DKO-AG-haESCs. PMID- 27709573 TI - Insertion of Group II Intron-Based Ribozyme Switches into Homing Endonuclease Genes. AB - Fungal mitochondrial genomes act as "reservoirs" for homing endonucleases. These enzymes with their DNA site-specific cleavage activities are attractive tools for genome editing, targeted mutagenesis and gene therapy applications. Herein, we present strategies where homing endonuclease open reading frames (HEases ORFs) are interrupted with group II intron sequences. The ultimate goal is to achieve in vivo expression of HEases that can be regulated by manipulating the splicing efficiency of the HEase ORF-embedded group II introns. That addition of exogenous magnesium chloride (MgCl2) appears to stimulate splicing of nonnative group II introns in Escherichia coli and the addition of cobalt chloride (CoCl2) to the growth medium antagonizes the expression of HEase activity (i.e., splicing). Group II introns are potentially autocatalytic self-splicing elements and thus can be used as molecular switches that allow for temporal regulated HEase expression. This should be useful in precision genome engineering, mutagenesis, and minimizing off-target activities. PMID- 27709574 TI - Generating a Genome Editing Nuclease for Targeted Mutagenesis in Human Cells. AB - Gene targeting and editing is an essential tool for both basic research and clinical application such as gene therapy. Several endonucleases have been invented to fulfill these purposes, including zinc finger nucleases, TALEN, and CRISPR/Cas9. Although all of these systems can target DNA sequence with high efficiency, they also exert off-target effects and genotoxicity. The off-target effects might not hinder their usage in animal models because the correctly targeted cells can be selected for further studies. However, the off-target effects could cause mutations which may be damaging or cancerous to the patients. In this chapter, we describe a genome-editing nuclease method which relies on modifying specific amino acids on a monomeric endonuclease, I-SceI, to recognize a targeted sequence in the human genome. This nuclease is small in size and shows a much lower genotoxicity compared to other nucleases including CRISPR/Cas9. PMID- 27709575 TI - Use of Group II Intron Technology for Targeted Mutagenesis in Chlamydia trachomatis. AB - Dissecting the contribution of genes to virulence in fulfillment of Molecular Koch's postulates is essential for developing prevention and treatment strategies for bacterial pathogens. This chapter will discuss the application of a targeted, intron-based insertional mutagenesis method for creating mutants in the obligate, intracellular bacterial pathogen Chlamydia trachomatis. The methods employed for intron targeting, mutant selection, and mutant verification will be outlined including available selection markers, gene targeting strategies, and potential pitfalls. PMID- 27709577 TI - In Silico Prediction of Deleteriousness for Nonsynonymous and Splice-Altering Single Nucleotide Variants in the Human Genome. AB - In silico prediction methods have increasingly been valuable and popular in molecular biology, especially in human genetics, for deleteriousness prediction to filter and prioritize huge amounts of DNA variation identified by sequencing human genomes. There is a rich collection of available methods developed upon different levels/aspects of knowledge about how DNA variations affect gene expression. Given the fact that their predictions are not always consistent or even opposite of what was expected, using consensus prediction or majority vote among these methods is preferred to trusting any single one. Because querying different databases for different methods is both tedious and time-consuming for such big data sets, one database integrating predictions from multiple databases can facilitate the process. In this chapter, we describe the general steps of obtaining comprehensive predictions and annotations for large numbers of variants from dbNSFP, the first and probably the most widely used database of its kind. PMID- 27709576 TI - In Silico Approaches to Identify Mutagenesis Targets to Probe and Alter Protein Cofactor and Protein-Protein Functional Relationships. AB - When performing site-directed mutagenesis experiments to study protein structure function relationships, ideally one would know the structure of the protein under study. It is also very useful to have structures of multiple related proteins in order to determine whether or not particular amino acid residues are conserved in the structures either in the active site of an enzyme at the surface of a protein or at a putative protein-protein interface. While many protein structures are available in the Protein Data Base (PDB), a structure of the protein of interest may not be available. In the study of reversible and often transient protein protein interactions it is rare to have a structure of the complex of the two interacting proteins. In this chapter, methods are described for comparing protein structures, generating putative structures of proteins with homology models based on the protein primary sequence, and generating docking models to predict interaction sites between proteins and cofactor-protein interactions. The rationale used to predict mutagenesis targets from these structures and models is also described. PMID- 27709578 TI - In Silico Methods for Analyzing Mutagenesis Targets. AB - Molecular dynamics of complex biological and chemical systems is possible using personal computers due to increased computer performance and improved software design. Here we describe molecular dynamics methods using Not Another Molecular Dynamics (NAMD) and Visual Molecular Dynamics (VMD) programs that aid in understanding the structural effects a mutation has on a protein. We describe in silico methods for site-specific mutation to standard and phosphorylated amino acids. Molecular dynamics equilibrations are used to provide a means for measuring structural fluctuations. These fluctuations assist in defining a distance coordinate, or reaction coordinate, that is relevant to the function of the protein. Adaptive biasing force molecular dynamics are then demonstrated to evaluate the energy landscape, or potential of mean force, along the chosen reaction coordinate. The potential of mean force identifies variations of the predominant structures among mutants that may affect function. PMID- 27709579 TI - Methods for Detecting Critical Residues in Proteins. AB - In proteins, certain amino acids may play a critical role in determining their structure and function. Examples include flexible regions, which allow domain motions, and highly conserved residues on functional interfaces, which play a role in binding and interaction with other proteins. Detecting these regions facilitates the analysis and simulation of protein rigidity and conformational changes, and aids in characterizing protein-protein binding. We present a protocol that combines graph-theory rigidity analysis and machine-learning-based methods for predicting critical residues in proteins. Our approach combines amino acid specific information and data obtained by two complementary methods. One method, KINARI, performs graph-based analysis to find rigid clusters of amino acids in a protein, while the other method relies on evolutionary conservation scores to find functional interfaces in proteins. Our machine learning model combines both methods, in addition to amino acid type and solvent-accessible surface area. PMID- 27709580 TI - A Method for Bioinformatic Analysis of Transposon Insertion Sequencing (INSeq) Results for Identification of Microbial Fitness Determinants. AB - Transposon insertion sequencing is a process whereby microbial fitness determinants can be identified on a genome-wide scale. This process uses high throughput next generation sequencing to screen for changes in the composition of a pool of transposon mutants after exposure to selective conditions. One commonly used process for generating transposon insertion sequencing libraries is called INSeq that works with mutant pools produced using a modified Mariner transposon. Libraries produced using the INSeq process are sequenced on the Illumina platform. In this chapter, we describe our method for processing the raw Illumina sequencing reads, aligning the reads to a reference sequence to determine read counts, and using the online transposon insertion sequencing data analysis server, ESSENTIALS, to interpret the results. PMID- 27709581 TI - Application of In Vitro Transposon Mutagenesis to Erythromycin Strain Improvement in Saccharopolyspora erythraea. AB - Transposon mutagenesis is an invaluable technique in molecular biology for the creation of random mutations that can be easily identified and mapped. However, in the field of microbial strain improvement, transposon mutagenesis has scarcely been used; instead, chemical and physical mutagenic methods have been traditionally favored. Transposons have the advantage of creating single mutations in the genome, making phenotype to genotype assignments less challenging than with traditional mutagens which commonly create multiple mutations in the genome. The site of a transposon mutation can also be readily mapped using DNA sequencing primer sites engineered into the transposon termini. In this chapter an in vitro method for transposon mutagenesis of Saccharopolyspora erythraea is presented. Since in vivo transposon tools are not available for most actinomycetes including S. erythraea, an in vitro method was developed. The in vitro method involves a significant investment in time and effort to create the mutants, but once the mutants are made and screened, a large number of highly relevant mutations of direct interest to erythromycin production can be found. PMID- 27709582 TI - Engineering Gram-Negative Microbial Cell Factories Using Transposon Vectors. AB - The construction of microbial cell factories a la carte largely depends on specialized molecular biology and synthetic biology tools needed to reprogram bacteria for modifying their existing functions or for bestowing them with new-to Nature tasks. In this chapter, we document the use of a series of broad-host range mini-Tn5 vectors for the delivery of gene(s) into the chromosome of Gram negative bacteria and for the generation of saturated, random mutagenesis libraries for studies of gene function. The application of these tailored mini transposon vectors, which could also be used for chromosomal engineering of a wide variety of Gram-negative microorganisms, is demonstrated in the platform environmental bacterium Pseudomonas putida KT2440. PMID- 27709583 TI - PERMutation Using Transposase Engineering (PERMUTE): A Simple Approach for Constructing Circularly Permuted Protein Libraries. AB - Rearrangements that alter the order of a protein's sequence are used in the lab to study protein folding, improve activity, and build molecular switches. One of the simplest ways to rearrange a protein sequence is through random circular permutation, where native protein termini are linked together and new termini are created elsewhere through random backbone fission. Transposase mutagenesis has emerged as a simple way to generate libraries encoding different circularly permuted variants of proteins. With this approach, a synthetic transposon (called a permuteposon) is randomly inserted throughout a circularized gene to generate vectors that express different permuted variants of a protein. In this chapter, we outline the protocol for constructing combinatorial libraries of circularly permuted proteins using transposase mutagenesis, and we describe the different permuteposons that have been developed to facilitate library construction. PMID- 27709584 TI - Transposon Insertion Mutagenesis for Archaeal Gene Discovery. AB - Archaea constitute the third domain of life, but studies on their physiology and other features have lagged behind bacteria and eukarya, largely due to the challenging biology of archaea and concomitant difficulties in methods development. The use of genome-wide en masse insertion mutagenesis is one of the most efficient means to discover the genes behind various biological functions, and such a methodology is described in this chapter for a model archaeon Haloferax volcanii. The strategy successfully employs efficient in vitro transposition in combination with gene targeting in vivo via homologous recombination. The methodology is general and should be transferable to other archaeal species. PMID- 27709585 TI - Genome-Wide Transposon Mutagenesis in Mycobacterium tuberculosis and Mycobacterium smegmatis. AB - TnSeq, or transposon (Tn) insertion sequencing, is a powerful method for identifying the essential-as well as conditionally essential-regions in a genome, both coding and noncoding. The advent of accessible massively parallel DNA sequencing technologies in particular has resulted in the increased use of TnSeq based approaches to elucidate various aspects of bacterial physiology and metabolism. Moreover, the availability of detailed protocols has enabled even nonspecialist laboratories to adapt and develop TnSeq approaches to address specific research questions. In this chapter, we describe a recently modified experimental protocol used in our laboratory for TnSeq in the major human pathogen, Mycobacterium tuberculosis, as well as the related non-pathogenic mycobacterium, M. smegmatis. The method, which was developed in close consultation with pioneers in the field of mycobacterial genetics, includes the steps involved in preparing a phage stock, generating a mutant library, selection of the library under a specific experimental condition, isolation of genomic DNA from the pooled population of mutants, amplification of the sites of Tn insertion and, finally, determining the essential genomic regions by next-generation sequencing.

AB - Constructing protein-coding genes with desired mutations is a basic step for protein engineering. Herein, we describe a multiple site-directed and saturation mutagenesis method, termed MUPAC. This method has been used to introduce multiple site-directed mutations in the green fluorescent protein gene and in the moloney murine leukemia virus reverse transcriptase gene. Moreover, this method was also successfully used to introduce randomized codons at five desired positions in the green fluorescent protein gene, and for simple DNA assembly for cloning. PMID- 27709587 TI - Seamless Ligation Cloning Extract (SLiCE) Method Using Cell Lysates from Laboratory Escherichia coli Strains and its Application to SLiP Site-Directed Mutagenesis. AB - Cell lysates from laboratory Escherichia coli strains endogenously exhibit homologous recombination activity, which can be utilized for seamless DNA cloning in vitro. This method, termed Seamless Ligation Cloning Extract (SLiCE) cloning, enables high cloning efficiency with simultaneous integration of two unpurified DNA fragments into a vector. In addition, the SLiCE method is highly cost effective, as several laboratory E. coli strains may be utilized as sources of SLiCE. Previously, the SLiCE technique has been applied to site-directed mutagenesis to develop a novel technique termed SLiCE-mediated polymerase chain reaction (PCR)-based site-directed mutagenesis (SLiP site-directed mutagenesis). Two DNA fragments containing a mutation site can be simultaneously integrated into a vector while avoiding the introduction of undesirable mutations in the vector. Therefore, SLiP site-directed mutagenesis simplifies multiple procedures involved in PCR-based site-directed mutagenesis such as overlap extension method PCR or the Megaprimer method.

AB - Site-directed mutagenesis is a commonly used molecular biology technique to manipulate biological sequences, and is especially useful for studying sequence determinants of enzyme function or designing proteins with improved activity. We describe a strategy using Gibson Isothermal DNA Assembly to perform site-directed mutagenesis on large (>~20 kbp) constructs that are outside the effective range of standard techniques such as QuikChange II (Agilent Technologies), but more reliable than traditional cloning using restriction enzymes and ligation. PMID- 27709589 TI - Revised Mechanism and Improved Efficiency of the QuikChange Site-Directed Mutagenesis Method. AB - Site-directed mutagenesis has been widely used for the substitution, addition or deletion of nucleotide residues in a defined DNA sequence. QuikChangeTM site directed mutagenesis and its related protocols have been widely used for this purpose because of convenience and efficiency. We have recently demonstrated that the mechanism of the QuikChangeTM site-directed mutagenesis process is different from that being proposed. The new mechanism promotes the use of partially overlapping primers and commercial PCR enzymes for efficient PCR and mutagenesis. PMID- 27709590 TI - An In Vitro Single-Primer Site-Directed Mutagenesis Method for Use in Biotechnology. AB - Site-directed mutagenesis is a powerful method to introduce mutation(s) into DNA sequences. A number of methods have been developed over the years with a main goal being to create a high number of mutant genes. The single-mutagenic primer method for site-directed mutagenesis is the most direct method that yields mutant genes in about 25-50 % of transformants in a robust, low-cost reaction. The supercompetent XL10-Gold bacteria used in the Stratagene protocol carry a phage, which may be a problem for some applications; however, in our single-mutagenic primer method the supercompetent bacteria are not needed. A thermostable DNA polymerase with high fidelity and processivity, such as Phusion DNA polymerase, is required for our optimized procedure to avoid extra mutation(s) and enhance mutagenic efficiency.

AB - Protein engineering is a very useful tool for probing structure-function relationships in proteins. Specifically, site-directed mutagenized proteins can provide useful insights into structural, binding and catalytic mechanisms of a protein, particularly when coupled with crystallization. In this chapter, we describe two protocols for performing site-directed mutagenesis of any protein coding sequence, namely, megaprimer PCR and overlapping extension PCR (OE-PCR). We use as an example how these two SDM methods enhanced the function of a cyclodextrin glucosyltransferase (CGTase) from Bacillus lehensis strain G1. PMID- 27709592 TI - Step-By-Step In Vitro Mutagenesis: Lessons From Fucose-Binding Lectin PA-IIL. AB - Site-directed mutagenesis is a powerful technique which is used to understand the basis of interactions between proteins and their binding partners, as well as to modify these interactions. Methods of rational design that are based on detailed knowledge of the structure of a protein of interest are often used for preliminary investigations of the possible outcomes which can result from the practical application of site-directed mutagenesis. Also, random mutagenesis can be used in tandem with site-directed mutagenesis for an examination of amino acid "hotspots."Lectins are sugar-binding proteins which, among other functions, mediate the recognition of host cells by a pathogen and its adhesion to the host cell surface. Hence, lectins and their binding properties are studied and engineered using site-directed mutagenesis.In this chapter, we describe a site directed mutagenesis method used for investigating the sugar binding pattern of the PA-IIL lectin from the pathogenic bacterium Pseudomonas aeruginosa. Moreover, procedures for the production and purification of PA-IIL mutants are described, and several basic methods for characterizing the mutants are discussed. PMID- 27709593 TI - Analytical Methods for Assessing the Effects of Site-Directed Mutagenesis on Protein-Cofactor and Protein-Protein Functional Relationships. AB - To completely understand the role of an amino acid residue that is targeted for site-directed mutagenesis a thorough analysis of the impact that the mutation has on the function of the protein is required. General methods for performing site directed mutagenesis and expressing the recombinant protein variant are described. Protein-cofactor interactions are important because cofactors are often directly involved in facilitating catalysis by enzymes and in electron transfer by redox proteins. Many cofactors also have characteristic spectroscopic properties. As such, general methods are described to analyze the spectroscopic, redox and catalytic properties of protein-bound cofactors. Methods for assessing the effects of a mutation on protein-protein interactions are also described. Lastly, methods for assessing the overall structural integrity of the protein are described, as this is important to ensure that the mutation has not caused a global disruption of protein structure, rather than a specific effect on function. PMID- 27709594 TI - Biochemical and Biophysical Methods to Examine the Effects of Site-Directed Mutagenesis on Enzymatic Activities and Interprotein Interactions. AB - Mutations in proteins often affect interactions with partner molecules, sequentially changing their activities and functions. In order to examine mutagenic effects, we herein describe practical and detailed protocols for enzymatic activity assays using ferredoxin (Fd)-NADP+ reductase (FNR) and sulfite reductase (SiR), which are electron-transferring enzymes for the Calvin cycle and sulfur assimilation in various organisms, respectively. Methods for isothermal titration calorimetry and nuclear magnetic resonance spectroscopy, which are very useful thermodynamically and mechanically for investigating the effects of mutations on intermolecular interactions, are also described with practical examples of the Fd-FNR binding system.

AB - Mutagenesis is a valuable tool to examine the structure-function relationships of bacterial proteins. As such, a wide variety of mutagenesis techniques and strategies have been developed. This chapter details a selection of random mutagenesis methods and site-directed mutagenesis procedures that can be applied to an array of bacterial species. Additionally, the direct application of the techniques to study the Helicobacter pylori Ferric Uptake Regulator (Fur) protein is described. The varied approaches illustrated herein allow the robust investigation of the structural-functional relationships within a protein of interest. PMID- 27709596 TI - Novel Random Mutagenesis Method for Directed Evolution. AB - Directed evolution is a powerful strategy for gene mutagenesis, and has been used for protein engineering both in scientific research and in the biotechnology industry. The routine method for directed evolution was developed by Stemmer in 1994 (Stemmer, Proc Natl Acad Sci USA 91, 10747-10751, 1994; Stemmer, Nature 370, 389-391, 1994). Since then, various methods have been introduced, each of which has advantages and limitations depending upon the targeted genes and procedure. In this chapter, a novel alternative directed evolution method which combines mutagenesis PCR with dITP and fragmentation by endonuclease V is described. The kanamycin resistance gene is used as a reporter gene to verify the novel method for directed evolution. This method for directed evolution has been demonstrated to be efficient, reproducible, and easy to manipulate in practice. PMID- 27709597 TI - Random Mutagenesis by Error-Prone Polymerase Chain Reaction Using a Heavy Water Solvent. AB - Heavy water is a form of water that contains a heavier isotope of hydrogen (2H, also known as deuterium, D) or oxygen (17O or 18O). When using heavy water as a solvent, error-prone polymerase chain reaction (epPCR) can induce random mutations independent of the polymerase used or the composition of the PCR reaction mixture. This relatively new method can easily be combined with the existing epPCR methods to increase the rate of mutations. PMID- 27709598 TI - Development and Use of a Novel Random Mutagenesis Method: In Situ Error-Prone PCR (is-epPCR). AB - Directed evolution methods are increasingly needed to improve gene and protein properties. Error-prone PCR is the most efficient method to introduce random mutations by reducing the fidelity of the DNA polymerase. However, a highly efficient process is required for constructing and screening a diverse mutagenesis library since a large pool of transformants is needed to generate a desired mutant. We developed a method called in situ error-prone PCR (is-epPCR) to improve the efficiency of constructing a mutation library for directed evolution. This method offers the following advantages: (1) closed-circular PCR products can be directly transformed into competent E. coli cells and easily selected by using an alternative antibiotic; (2) a mutant library can be created and screened by one-step error-prone amplification of a variable DNA region in an expression plasmid; and (3) accumulation of desired mutations in one sequence can be obtained by multiple rounds of is-epPCR. Is-epPCR offers a novel, convenient, and efficient approach for improving genes and proteins through directed evolution. PMID- 27709599 TI - Cathepsin K expression in melanoma is associated with metastases. AB - INTRODUCTION: Melanoma of the skin shows a tendency to metastasize via lymph or blood secreting matrix metalloproteinases and cathepsins, which enable penetration through the dermis. Cathepsin K acts in cytoplasm of atypical melanocytes and completely cleaves internalized collagen. MATERIALS AND METHODS: Expression of cathepsin K was analyzed immunohistochemically in 45 melanomas and correlated to morphological and clinical parameters. RESULTS: During six years follow up, 13 patients developed lymph node metastases and three of them distant metastases. Positive expression of cathepsin K was found in 19 cases. In univariate regression analysis histological type, pagetoid spread, mitotic activity and cathepsin K expression were significantly connected to metastases. Cathepsin K was significantly associated to histologic type, ulceration, pagetoid spread and mitotic rate. In multiple logistic regression adjusted to these variables, cathepsin K was an independent predictor in occurrence of metastases (P=0.015). Median to the occurrence of metastases was 40 months in patients with cathepsin K positive expression and 71 months in patients with cathepsin K negative expression (P<0.001). CONCLUSIONS: In this preliminary study positive expression of cathepsin K in melanoma of the skin is associated with other unfavorable prognostic factors. We consider cathepsin K expression in primary tumor would significantly precipitate occurrence of metastases.

AB - PURPOSE: This study evaluated the relationships of the size and number of superficial groin lymph nodes with the lower limb lymphedema stage and thus examined the role of superficial lymphatic lymph nodes in secondary lymphedema development. METHODS: We determined the number and size of superficial groin lymph nodes using horizontal plane computed tomography (CT) and the lymphedema stage in the lower limbs of 25 patients with gynecologic cancer. RESULTS: The patients had an average of 2.92 (range, 1-7) superficial groin lymph nodes; the mean size of the 146 evaluated lymph nodes was 7.55 mm (range, 5-15 mm). In 19 of 25 patients (76%), the side with major edema contained fewer superficial groin lymph nodes. In total, 22 patients (88%) had fewer superficial groin lymph nodes or a smaller total lymph node size on the edematous dominant side. CONCLUSIONS: In this evaluation of the link between superficial groin lymph node laterality and secondary lymphedema staging, we found that patients with large lymph node numbers and sizes tended to present with a relatively earlier stage of lymphedema. Our results therefore suggest that the size and number of superficial groin lymph nodes affect the lymphedema stage. J. Surg. Oncol. 2016;114:940-946. (c) 2016 Wiley Periodicals, Inc. PMID- 27709600 TI - Cost-Effectiveness and Public Health Effect of Influenza Vaccine Strategies for U.S. Elderly Adults. AB - OBJECTIVES: To compare the cost-effectiveness of four influenza vaccines available in the United States for persons aged 65 and older: trivalent inactivated influenza vaccine (IIV3), quadrivalent inactivated influenza vaccine (IIV4), a more-expensive high-dose IIV3, and a newly approved adjuvanted IIV3. DESIGN: Cost-effectiveness analysis using a Markov model and sensitivity analyses. SETTING: A hypothetical influenza vaccination season modeled according to possible U.S. influenza vaccination policies. PARTICIPANTS: Hypothetical cohort of individuals aged 65 and older in the United States. MEASUREMENTS: Cost effectiveness and public health benefits of available influenza vaccination strategies in U.S. elderly adults. RESULTS: IIV3 cost $3,690 per quality-adjusted life year (QALY) gained, IIV4 cost $20,939 more than IIV3 per QALY gained, and high-dose IIV3 cost $31,214 more per QALY than IIV4. The model projected 83,775 fewer influenza cases and 980 fewer deaths with high-dose IIV3 than with the next most-effective vaccine: IIV4. In a probabilistic sensitivity analysis, high-dose IIV3 was the favored strategy if willingness to pay is $25,000 or more per QALY gained. Adjuvanted IIV3 cost-effectiveness depends on its price and effectiveness (neither yet determined in the United States) but could be favored if its relative effectiveness is 15% greater than that of IIV3. CONCLUSION: From economic and public health standpoints, high-dose IIV3 for adults aged 65 years and older is likely to be favored over the other vaccines, based on currently available data. The cost-effectiveness of adjuvanted IIV3 should be reviewed after its effectiveness has been compared with that of other vaccines and its U.S. price is established. PMID- 27709602 TI - Responses to Interpersonal Stress: Normative Changes Across Childhood and the Impact of Peer Victimization. AB - This research examined the development of stress responses across second to sixth grades and whether exposure to peer victimization alters stress response trajectories. Youth (338 girls; 298 boys; Mage = 7.97 years, SD = .37) reported on stress responses; teachers and youth reported on peer victimization. Latent growth curve modeling revealed an increase in effortful engagement responses and a decrease in disengagement and involuntary engagement responses during this period. Peer victimization disrupted these normative trajectories, resulting in less effortful engagement and more effortful disengagement and involuntary stress responses in early adolescence. These findings suggest that early peer victimization sensitizes youth to stress by interfering with the development of effective coping and fostering maladaptive stress responses. PMID- 27709604 TI - Annual Research Review: Quality of life and childhood mental and behavioural disorders - a critical review of the research. AB - BACKGROUND: An individual's subjective perception of well-being is increasingly recognized as an essential complement to clinical symptomatology and functional impairment in children's mental health. Measurement of quality of life (QoL) has the potential to give due weight to the child's perspective. SCOPE AND METHODOLOGY: Our aim was to critically review the current evidence on how childhood mental disorders affect QoL. First, the major challenges in this research field are outlined. Then we present a systematic review of QoL in children and adolescents aged 0-18 years formally diagnosed with a mental and behavioural disorder, as compared to healthy or typically developing children or children with other health conditions. Finally, we discuss limitations of the current evidence base and future directions based on the results of the systematic review and other relevant literature. FINDINGS AND CONCLUSIONS: The systematic review identified 41 eligible studies. All were published after the year 2000 and 21 originated in Europe. The majority examined QoL in neurodevelopmental disorders, including attention-deficit hyperactivity disorder (k = 17), autism spectrum disorder (k = 6), motor disorders (k = 5) and intellectual disability (k = 4). Despite substantial heterogeneity, studies demonstrate that self-reported global QoL is significantly reduced compared to typical/healthy controls across several disorders and QoL dimensions. Parents' ratings were on average substantially lower, casting doubt on the validity of proxy-report. Studies for large diagnostic groups such as depressive disorders, anxiety disorders, (early onset) schizophrenia and eating disorders are largely lacking. We conclude that representative, well-characterized normative and clinical samples as well as longitudinal and qualitative designs are needed to further clarify the construct of QoL, to derive measures of high ecological validity, and to examine how QoL fluctuates over time and is attributable to specific conditions or contextual factors. PMID- 27709603 TI - Does the colonization of new biogeographic regions influence the diversification and accumulation of clade richness among the Corvides (Aves: Passeriformes)? AB - Regional variation in clade richness can be vast, reflecting differences in the dynamics of historical dispersal and diversification among lineages. Although it has been proposed that dispersal into new biogeographic regions may facilitate diversification, to date there has been limited assessment of the importance of this process in the generation, and maintenance, of broad-scale biodiversity gradients. To address this issue, we analytically derive biogeographic regions for a global radiation of passerine birds (the Corvides, c. 790 species) that are highly variable in the geographic and taxonomic distribution of species. Subsequently, we determine rates of historical dispersal between regions, the dynamics of diversification following regional colonization, and spatial variation in the distribution of species that differ in their rates of lineage diversification. The results of these analyses reveal spatiotemporal differences in the build-up of lineages across regions. The number of regions occupied and the rate of transition between regions both predict family richness well, indicating that the accumulation of high clade richness is associated with repeated expansion into new geographic areas. However, only the largest family (the Corvidae) had significantly heightened rates of both speciation and regional transition, implying that repeated regional colonization is not a general mechanism promoting lineage diversification among the Corvides. PMID- 27709606 TI - "We want the world and we want it now": Materialism, time perspectives and problem spending tendency of Chinese. AB - Chinese consumers' spending has been expanding rapidly in the past decade, and along with it household and credit card debt. The present research collected evidence to triangulate the contention that materialism is positively related with Chinese's problem spending tendency (PST), and that present-time-perspective (PTP) and future-time perspectives (FTP) interact systematically with materialism to affect PST. A survey of the general population in Macao, China (Study 1; N = 239) confirmed that materialism was positively correlated with PST. An interaction between materialism and PTP intensified the relationship, whereas an interaction with FTP weakened the relationship. Another survey with a sample of university students (Study 2; N = 223) again found positive relationships among PST, materialism, and PTP, as measured by temporal discount rate. But further exploration showed that PST was only related with temporal discounting among high materialists, but not among low materialists. Study 3 experimentally examined the causal effects of materialism and FTP on PST. When being primed of an orientation towards materialism (n = 33), the participants' planned consumption doubled that of the control group (n = 31). A FTP prime interacted with materialism prime and put a "damper" on participants' planned spending (n = 29), compared to their counterparts who were not primed of such a time perspective. PMID- 27709607 TI - The circular structure of values: The case of China. AB - This study examined the circular structure of values in China. The circular structure is a central element of Schwartz value theory and visualises the idea that some values are similar while others conflict with one another. Whereas numerous studies addressed the question whether the circular structure of values can be generalised cross-culturally, results for China are inconclusive. In this paper, we argue that taking a closer look at China provides a challenge to the circular structure and allows for drawing conclusions regarding the limits versus generalizability of Schwartz' theory. For this purpose, we first conduct a re analysis of Chinese data from a former meta-analysis (Study 1) and second, present results from a large study of 10,652 Chinese college students (Study 2). Results of Study 1 revealed that graphical representation of the circular structure matched theoretical expectations but five out of six samples showed relatively bad fit to the theorised structure. By contrast, data in Study 2 showed a good model fit. As an overall conclusion, the circular structure is well supported in the Chinese context, and small sample sizes in previous studies might have caused the imperfect match to the prototypical circular structure. PMID- 27709605 TI - Fungal pattern receptors down-regulate the inflammatory response by a cross inhibitory mechanism independent of interleukin-10 production. AB - Cyclic AMP regulatory element binding protein and signal transducer and activator of transcription 3 (STAT3) may control inflammation by several mechanisms, one of the best characterized is the induction of the expression of the anti inflammatory cytokine interleukin-10 (IL-10). STAT3 also down-regulates the production of pro-inflammatory cytokines induced by immunoreceptor tyrosine-based activation motif (ITAM)-coupled receptors, a mechanism termed cross-inhibition. Because signalling via ITAM-dependent mechanisms is a hallmark of fungal pattern receptors, STAT3 activation might be involved in the cross-inhibition associated with invasive fungal infections. The fungal surrogate zymosan produced the phosphorylation of Y705-STAT3 and the expression of Ifnb1 and Socs3, but did not induce the interferon (IFN)-signature cytokines Cxcl9 and Cxcl10 in bone marrow derived dendritic cells. Unlike lipopolysaccharide (LPS), zymosan induced IL-10 and phosphorylated Y705-STAT3 to a similar extent in Irf3 and Ifnar1 knockout and wild-type mice. Human dendritic cells showed similar results, although the induction of IFNB1 was less prominent. These results indicate that LPS and zymosan activate STAT3 through different routes. Whereas type I IFN is the main effector of LPS effect, the mechanism involved in Y705-STAT3 phosphorylation by zymosan is more complex, cannot be associated with type I IFN, IL-6 or granulocyte-macrophage colony-stimulating factor, and seems dependent on several factors given that it was partially inhibited by the platelet-activating factor antagonist WEB2086 and high concentrations of COX inhibitors, p38 mitogen activate protein kinase inhibitors, and blockade of tumour necrosis factor-alpha function. Altogether, these results indicate that fungal pattern receptors share with other ITAM-coupled receptors the capacity to produce cross-inhibition through a mechanism involving STAT3 and induction of SOCS3 and IL-10, but that cannot be explained through type I IFN signalling.

PMID- 27709609 TI - How valuable is inpatient electroencephalogram for medical decision-making? AB - BACKGROUND: The electroencephalogram (EEG) can support the diagnosis of epilepsy, diagnose nonconvulsive status epilepticus and aid in the classification of epileptic seizures. Its contribution to the diagnosis of other medical conditions or to decision-making in other clinical situations was not established. Practically, EEG laboratories frequently encounter EEG referrals that are not based on current recommendations. OBJECTIVES: To assess the value of inpatient EEG in medical decision-making. METHODS: We retrospectively reviewed the inpatient computerized medical information management system and the EEG laboratory computerized database for all adult inpatient standard, sleep-deprived and bedside EEGs performed during a one-year period. Change in diagnosis and/or treatment and the clinical justification for ordering an EEG recording were determined. RESULTS: The study group included 584 patients, 313 (54%) men, aged 55.5 +/- 20.8 years (range 18-95 years). The EEG was clinically justified in 372 (63.7%) and led to change in diagnosis and/or treatment in 47 (8%) patients. These patients were significantly more likely to be admitted to the neurology department (P = 0.033), have an admission and discharge diagnosis of seizure or epilepsy (P = 0.0001), have a clinically justified EEG (P = 0.0001) and have an EEG recording with electrographic seizures (P = 0.0001), interictal epileptiform discharges (P = 0.0001) and background abnormalities (P = 0.003). CONCLUSIONS: Inpatient EEG can mostly contribute to diagnosis and treatment in patients with a seizure or epilepsy. An informed use of the EEG can increase its yield and reduce the number of unnecessary referrals, thus shortening waiting time and enabling earlier diagnosis and treatment in yet undiagnosed patients. PMID- 27709610 TI - Overt and Relational Victimization: A Meta-Analytic Review of Their Overlap and Associations With Social-Psychological Adjustment. AB - This meta-analytic review includes 135 studies, representing 17 countries, of child and adolescent (ages 4-17) samples of overt and relational peer victimization and examines the magnitude of overlap between forms of victimization and associations with five social-psychological adjustment indices. Results indicate a strong intercorrelation between forms of victimization (r- = .72). No gender difference with regard to relational victimization was found, but boys were slightly higher in overt victimization. Overt victimization is more strongly associated with overt aggression; relational victimization is more strongly related to internalizing problems, lower levels of received prosocial behavior from peers, and relational aggression. Both forms are related to externalizing problems. Age and method of assessment were explored as potential sources of variability in effect sizes.

PMID- 27709612 TI - Alpha-lipoic acid-stearylamine conjugate-based solid lipid nanoparticles for tamoxifen delivery: formulation, optimization, in-vivo pharmacokinetic and hepatotoxicity study. AB - OBJECTIVES: This study was designed to demonstrate the potential of novel alpha lipoic acid-stearylamine (ALA-SA) conjugate-based solid lipid nanoparticles in modulating the pharmacokinetics and hepatotoxicity of tamoxifen (TMX). METHODS: alpha-lipoic acid-stearylamine bioconjugate was synthesized via carbodiimide chemistry and used as a lipid moiety for the generation of TMX-loaded solid lipid nanoparticles (TMX-SLNs). TMX-SLNs were prepared by solvent emulsification diffusion method and optimized for maximum drug loading using rotatable central composite design. The optimized TMX-SLNs were stabilized using 10% w/w trehalose as cryoprotectant. In addition, pharmacokinetics and hepatotoxicity of freeze dried TMX-SLNs were also evaluated in Sprague Dawley rats. KEY FINDINGS: Initial characterization with transmission electron microscopy revealed spherical morphology with smooth surface having an average particle size of 261.08 +/- 2.13 nm. The observed entrapment efficiency was 40.73 +/- 2.83%. In-vitro release study showed TMX release was slow and pH dependent. Pharmacokinetic study revealed a 1.59-fold increase in relative bioavailability as compared to TMX suspension. A decrease in hepatotoxicity of TMX is evidenced by the histopathological evaluation of liver tissues. CONCLUSIONS: alpha-lipoic acid stearylamine conjugate-based SLNs have a great potential in enhancing the oral bioavailability of poorly soluble drugs like TMX. Moreover, this ALA-SA nanoparticulate system could be of significant value in long-term anticancer therapy with least side effects.

PMID- 27709614 TI - Adolescent adaptation before, during and in the aftermath of the Great Recession in the USA. AB - This study examines the impact of the "Great Recession" (from December 2007 to June 2009) on 8th and 10th graders in the USA, using annual nationally representative data from the Monitoring the Future study. Historical changes in youth adjustment (self-esteem, depressed mood, risk taking, aggression and property crime), school achievement (grade point average [GPA], time spent on homework and educational expectations) and structured and unstructured activities (volunteering, employment, sports and evenings out for fun) were examined between 1991 and 2014. Overall, there were only slight changes in mean levels of adjustment, achievement and most youth activities. However, the percentage of youth working during the school year did decline during the Great Recession. Several longer-term trends were also evident, though not directly tied to the Great Recession. These include an increase in GPA, a decrease in time spent on homework, rising educational expectations and more time spent volunteering. Future work should assess how the shift to unpaid work activities (e.g. volunteering and internships) among youth is impacting the transition from school to work in the contemporary economy, and whether the Great Recession had deleterious impacts for younger children or among youth whose parents lost work or had their homes foreclosed.

This complex interplay challenges established good manufacturing practices, as standards and analytical tools to measure regenerative potency are missing.

AB - H-NS family proteins play key roles in bacterial nucleoid compaction and global transcription. MvaT homologues in Pseudomonas have almost negligible amino acid sequence identity with H-NS, but can complement an hns-related phenotype of Escherichia coli. Here, we report the crystal structure of the N-terminal dimerization/oligomerization domain of TurB, an MvaT homologue in Pseudomonas putida KT2440. Our data identify two dimerization sites; the structure of the central dimerization site is almost the same as the corresponding region of H-NS, whereas the terminal dimerization sites are different. Our results reveal similarities and differences in dimerization and oligomerization mechanisms between H-NS and TurB. PMID- 27709617 TI - Use of accelerometry to investigate physical activity in dogs receiving chemotherapy. AB - OBJECTIVES: To perform a preliminary study to assess whether single-agent palliative or adjuvant chemotherapy has an impact on objectively measured physical activity in dogs. METHODS: Fifteen dogs with neoplasia (treatment group) wore ActiGraphTM accelerometers for 5-day periods before, during and after receiving single-agent adjuvant or palliative chemotherapy. Mean 5-day total physical activity and time spent in three different intensities of activity (sedentary, light-moderate and vigorous) before, during and after receiving chemotherapy were compared to a group of 15 healthy dogs (control group). Results were also compared within the treatment group across time. RESULTS: Prior to chemotherapy, treated dogs tended to be less active than control dogs. Treatment group dogs were slightly more active at restaging than they were prior to treatment but had similar activity levels to control dogs. Marked effects of chemotherapy on physical activity were not detected. Physical activity was slightly lower in treated dogs during chemotherapy when compared to control dogs but there was a slight increase in physical activity of treated dogs during chemotherapy when compared with pretreatment recordings. There was little change in the mean 5-day total physical activity between treated dogs during chemotherapy and at restaging but a mild decrease in time spent sedentary and increase in time spent in light-moderate activity at this comparison of time points. CLINICAL SIGNIFICANCE: Single-agent adjuvant or palliative chemotherapy had minimal impact on physical activity levels in dogs with neoplasia.

AB - BACKGROUND: Electric stimulation (E-stim) has been found to be an effective treatment in improving wound healing rates. However, the wound healing trajectory and its related predictors for complete wound closure (CWC) have not been reported with E-stim treatment. MATERIALS AND METHODS: This was a retrospective study. Data on 159 patients treated at an outpatient wound clinic utilizing combined intervention of E-stim and conventional care were included. The Kaplan Meier healing curve together with linear regression models depicted the percentage of patients with CWC against time. RESULTS: With 100, 112 and 140 days of treatment, the percentages of patients with CWC were 59.12%, 61.01% and 65.41%, respectively. Linear regression models predicted that all patients would achieve CWC by 21.55, 22.26 and 24.80 weeks, respectively. The speed for the increase in the number and percentage of patients with CWC peaked between 50-75 days of treatment. To optimize timely healing, referral to other treatment facilities or change of treatment protocol is warranted around the peak time. With the combined intervention of E-stim and conventional care, positive predictors for CWC included a shorter wound duration at initial evaluation (P = 0.005, OR = 3.10), better compliance with appointments (P = 0.007, OR = 3.38) and the diagnosis of venous leg ulcer (P = 0.001, OR = 3.88). CONCLUSIONS: This study provided preliminary data on wound healing trajectory and predictors with combined E-stim and conventional care. E-stim seemed to expedite wound healing; however, further research studies are needed. PMID- 27709620 TI - From population genomics to conservation and management: a workflow for targeted analysis of markers identified using genome-wide approaches in Atlantic salmon Salmo salar. AB - A genotyping assay for the Ion Torrent Ion PGM platform was developed for fast and cost-effective targeted genotyping of key single nucleotide polymorphisms (SNPs) earlier identified using a genome-wide SNP array in Atlantic salmon Salmo salar. The method comprised a simple primer design step for multiplex-polymerase chain reaction (PCR), followed by two rounds of Ion Torrent Ion PGM sequencing to empirically evaluate marker efficiency in large multiplexes and to optimise or exclude them when necessary. Of 282 primer pairs initially tested, 217 were successfully amplified, indicating good amplification success (>75%). These markers included the sdy partial gene product to determine genetic sex, as well as three additional modules comprising SNPs for assessing neutral genetic variation (NSNP = 150), examining functional genetic variation associated with sea age at maturity (NSNP = 5), and for performing genetic subpopulation assignment (NSNP = 61). The assay was primarily developed to monitor long-term genetic changes in S. salar from the Teno River, but modules are likely suitable for application in a wide range of S. salar populations. Furthermore, the fast and versatile assay development pipeline offers a strategy for developing targeted sequencing assays in any species. PMID- 27709619 TI - The use of disposable skin staples for intestinal resection and anastomosis in 63 dogs: 2000 to 2014. AB - OBJECTIVE: To describe the use of disposable skin staples for intestinal resection and anastomosis in dogs and report associated dehiscence and mortality rates. METHODS: Retrospective evaluation of medical records of dogs that underwent intestinal resection and anastomosis using disposable skin staples between 2000 and 2014. Data regarding patient signalment, indication for surgery, location of the resection and anastomosis, number of procedures performed, evidence of peritonitis at the time of surgery, surgeon qualifications, dehiscence, and mortality were obtained from the medical records. Mortality was defined as failure to survive beyond 10 days following resection and anastomosis. RESULTS: The overall mortality rate of patients undergoing intestinal resection and anastomosis was 12.7% (8/63). The most common indication for resection and anastomosis was neoplasia (20/63 [31.7%]), followed by foreign body removal (19/63 [30.2%]). The overall dehiscence rate was 4.8% (3/63). No difference in mortality associated with indication for surgery, whether multiple procedures were performed, surgeon qualifications, or evidence of peritonitis at the time of surgery was identified. CLINICAL SIGNIFICANCE: In this retrospective study, the overall mortality and dehiscence rates using disposable skin staples were similar to previously reported outcomes following resection and anastomosis.

PMID- 27709623 TI - Refractive indices of organo-metallic and -metalloid compounds: A long-range corrected DFT study. AB - Refractive indices of metal- and metalloid-containing compounds are systematically evaluated using the Lorentz-Lorenz equation with polarizabilities obtained via density functional theory (DFT). Among exchange-correlation functionals studied, the long-range corrected (LC) fuctionals yield the lowest errors for the polarizabilities of gaseous compounds and refractive indices of liquids. The LC-DFT predicts very well the wavelength dependence of refractive indices. A scheme for computing Abbe numbers of organometallic and organometaloid compounds is proposed and a refractive index - Abbe number plot for 80 compounds is constructed. The compounds containing heavier metals tend to have higher refractive index and lower Abbe number, but several outliers, among them Te(CH3 )2 , Ni(PF3 )4 , Sb(C2 F3 )3 , Hg(C2 F3 )2 , are found. For Hg(C2 F3 )2 , also the effect of intramolecular and intermolecular degrees of freedom on polarizability is investigated. The absolute relative error in polarizability decreases from 5.7% for monomer model to 1.7% when a dimer model (derived from the available experimental crystal data) is employed.

AB - BACKGROUND: Anaphylaxis is a life-threatening emergency of which reliable epidemiological data are lacking. This study aimed to analyze how quickly patients presenting with anaphylaxis were treated in emergency and whether treatment followed the European Academy of Allergy and Clinical Immunology (EAACI) guidelines. METHODS: Patient data were collected between April 2009 and April 2013. Emergency doctors completed a questionnaire for adult patients presenting at the emergency department (ED) of the St. Pierre hospital in Brussels with anaphylaxis. Inclusion criteria were based on the Sampson criteria of anaphylaxis. Data were analyzed using a Microsoft Excel database. RESULTS: About 0.04% (100/230878) of all emergency visits in adults presented with anaphylaxis. 64% of patients received their first medical help later than 30 min after symptom onset. 67% of patients received adrenaline, 85% oral antihistamines, and 89% received IV glucocorticosteroids. 46/100 patients were discharged directly from the ED, of which 87% received further medical prescriptions for self-administration: 67% corticosteroids, 83% antihistamines, and 9% intramuscular adrenaline. 74% were instructed to consult an allergologist for adequate diagnosis. 54/100 patients were hospitalized. CONCLUSION: The majority of patients were treated according to the EAACI guidelines for management of anaphylaxis, but only a minority received the recommended adrenaline auto-injector for self-administration at discharge. Because the majority of patients received medical help later than 30 min after symptom onset, adrenaline auto-injector prescription is a necessity. The low rate of doctors prescribing adrenaline auto-injectors in the ED setting underlines the need to train doctors of various backgrounds in prevention and treatment of anaphylaxis and the close collaboration with allergologists.

AB - The human nail is one of the challenging membranes for the scientists to target and to improve the clinical efficacy of ungual formulations. The understanding of nail physiology, impact of hydration on its properties and presence of trace elements in nails as biomarkers has been explored by various researchers in clinical studies. Despite the importance of biophysical techniques for the assessment of structure and physiology of nail, minimum literature analyses biophysical, biochemical and bioanalytical approaches. However, nowadays scientists in bioengineering field are keen in developing non-invasive, reliable and reproducible techniques for the assessment of different anatomical and functional parameters of nails for testing of ungual products.

PMID- 27709626 TI - Long-term quality of life after transoral laser microsurgery for laryngeal carcinoma. AB - BACKGROUND AND OBJECTIVES: Previous studies showed good short-term Quality of life (QOL) after Transoral Laser Microsurgery (TLM) for laryngeal cancer. Here, we aimed to evaluate QOL after TLM in the long-term. METHODS: Prospective longitudinal study. Sixty-two consecutive disease-free patients were evaluated using UW-QOL v4 and SF-12 questionnaires, 1 and 5 years after TLM. Changes over time were assessed according to age, location, and tumor size. Long-term VHI-10 was also evaluated. RESULTS: The mean follow-up time was 5.41 +/- 2.02 years. No differences in the global UW-QOL score were observed between 1 and 5 years after TLM (1135.00 vs. 1127.20; P = 0.4). Activity worsened slightly in the long-term (93.03 vs. 87.70; P = 0.02). Forty-two and 58% of the patients reported that their health 1 and 5 years after treatment was much better than prior to diagnosis. Initially, 3.3% considered their health much worse, which was reduced to 1.7% at 5 years. SF-12 scores remained unchanged for both physical and mental aspects (P > 0.05). The VHI-10 was 3.81 +/- 5.7 for supraglottic and 7.2 +/- 9.6 for glottic tumors. CONCLUSION: Patients treated with TLM present a very good long-term QOL. Only activity deteriorates over time, while voice and swallowing remain satisfactory in the majority of patients. J. Surg. Oncol. 2016;114:789 795. (c) 2016 2016 Wiley Periodicals, Inc. PMID- 27709628 TI - Not your average bigot: The better-than-average effect and defensive responding to Implicit Association Test feedback. AB - A robust body of literature on the better-than-average effect suggests that people believe that they are better than the average others across a variety of domains. In two studies, we examined whether these better-than-average beliefs occur for bias related to stereotyping and prejudice. Moreover, we investigated the hypothesis that better-than-average beliefs will predict defensive responding to feedback indicating personal bias (e.g., preferences for majority groups, societally endorsed stereotypes). Specifically, we examined defensive responses to implicit attitude feedback. Study 1 examined this prediction using archival analysis of two large, online samples of participants completing a Weight-related Implicit Association Test (IAT). Study 2 conceptually replicated Study 1 using nine different, randomly assigned IATs and additional measures of defensiveness. In both studies, people generally believed that they were less biased than others. Moreover, people responded defensively to feedback indicating they were biased. This effect was moderated by better-than-average beliefs such that feedback indicating societally consistent bias was related to defensiveness most (and sometimes only) when people believed they were better than average initially. This work represents the first foray into examining the possible moderating role of social-comparative beliefs in predicting responses to implicit attitude feedback and spurs several important avenues for future research. PMID- 27709629 TI - Development of hepatocellular carcinoma in chronic hepatitis B patients with advanced fibrosis is independent of viral genotype. AB - Hepatitis B is leading cause of liver related morbidity in Asia with predominant genotypes B and C in East-Asia. Data on Serum, intrahepatic viral-markers, and long-term follow-up of prevalent genotypes (GT) B and C in patients with biopsy proven advanced fibrosis are sparse. To compare serum, intrahepatic viral-markers and development of hepatocellular carcinoma (HCC) in GT-B and C in patients with advanced fibrosis (Ishak >= 4). Sixty-three treatment-naive patients identified with advanced fibrosis on liver-biopsy performed between 1998 and 2000 at Singapore General Hospital. FFPE tissue was available for 59 patients and serum for 42 patients. HBV-DNA was quantified in serum and liver while qHBsAg quantified in serum. Patients were followed-up till December 2015. The median age was 47 +/- 16 years, with 77.7% males. About 19 were GT-B, 43 patients were GT-C, and 1 had both GT-B and C. Mean follow-up was 13.5 years. The median serum HBV DNA was 6.25 +/- 2.17 and 6.58 +/- 1.85 log IU/ml, serum HBsAg was 3.29 +/- 0.80 and 3.45 +/- 1.85 log IU/ml, and intrahepatic HBV-DNA was 0.52 +/- 3.73 copies/cell and 0.4 +/- 1.37 copies/cell in the GT-B and C, respectively (P > 0.1 in all). Complete cirrhosis (Ishak-6) was present in 47.6%, Ishak-5 fibrosis in 33.3%, and Ishak-4 fibrosis in 19% at recruitment. On follow-up HCC developed in 8/43 in GT-C and in 3/19 GT-B (P = 0.86). Advanced age and cirrhosis were significant factors for development of HCC. No difference in serum HBV-DNA, qHBsAg or intrahepatic HBV-DNA was seen in the two genotypes. HCC development seen over long-term follow-up was independent of genotypes in patients with advanced fibrosis. J. Med. Virol. 89:845-848, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27709630 TI - Myeloid-derived suppressor cell-like fibrocytes are increased and associated with preserved lung function in chronic obstructive pulmonary disease. AB - BACKGROUND: The role of fibrocytes in chronic obstructive pulmonary disease (COPD) is unknown. We sought to enumerate blood and tissue fibrocytes in COPD and determine the association of blood fibrocytes with clinical features of disease. METHODS: Utilizing flow cytometry to identify circulating, collagen type 1+ cells, we found two populations: (i) CD45+ CD34+ (fibrocytes) and (ii) CD45+ CD34 [myeloid-derived suppressor cell (MDSC)-like fibrocytes] cells in stable COPD (n = 41) and control (n = 29) subjects. Lung resection material from a separate group of subjects with (n = 11) or without (n = 11) COPD was collected for tissue fibrocyte detection. We examined circulating fibrocyte populations for correlations with clinical parameters including quantitative computed tomography (qCT) and determined pathways of association between correlated variables using a path analysis model. RESULTS: Blood and tissue fibrocytes were not increased compared to control subjects nor were blood fibrocytes associated with lung function or qCT, but were increased in eosinophilic COPD. Myeloid-derived suppressor cell-like fibrocytes were increased in COPD compared to controls [2.3 (1.1-4.9), P = 0.038]. Our path analysis model showed that collagen type 1 intensity for MDSC-like fibrocytes was positively associated with lung function through associations with air trapping, predominately in the upper lobes. CONCLUSION: We have demonstrated that two circulating populations of fibrocyte exist in COPD, with distinct clinical associations, but are not prevalent in proximal or small airway tissue. Blood MDSC-like fibrocytes, however, are increased and associated with preserved lung function through a small airway dependent mechanism in COPD. PMID- 27709631 TI - Associations between lifestyle factors and hand eczema severity: are tobacco smoking, obesity and stress significantly linked to eczema severity? AB - BACKGROUND: It has been suggested that lifestyle factors such as smoking, overweight and stress may influence the prevalence and severity of hand eczema. OBJECTIVES: To investigate the association between lifestyle factors and hand eczema severity in a cohort of patients with work-related hand eczema. METHODS: Individuals with work-related hand eczema notified in the period between June 2012 and November 2013 were included in this questionnaire-based cross-sectional study. Participants responded to a questionnaire including questions on lifestyle factors, as well as a photographic guide for assessment of severity of hand eczema and questions on quality of life. RESULTS: A total of 773 individuals (546 women and 227 men) responded to the questionnaire and were included in the study. A strong association was found between tobacco smoking and hand eczema severity (p = 0.003), whereas no significant association was found for body weight and stress. Other factors linked to severe eczema were male sex and older age (p = 0.04 and p = 0.01, respectively), and wet work (p = 0.08). CONCLUSION: The data from the present study strongly support an association between smoking and hand eczema severity. However, owing to the cross-sectional design of the study, no conclusion on causation can be drawn. PMID- 27709632 TI - Psychological Empowerment Among Urban Youth: Measurement Model and Associations with Youth Outcomes. AB - Empowerment-based strategies have become widely used method to address health inequities and promote social change. Few researchers, however, have tested theoretical models of empowerment, including multidimensional, higher-order models. We test empirically a multidimensional, higher-order model of psychological empowerment (PE), guided by Zimmerman's conceptual framework including three components of PE: intrapersonal, interactional, and behavioral. We also investigate if PE is associated with positive and negative outcomes among youth. The sample included 367 middle school youth aged 11-16 (M = 12.71; SD = 0.91); 60% female, 32% (n = 117) white youth, 46% (n = 170) African-American youth, and 22% (n = 80) identifying as mixed race, Asian-American, Latino, Native American, or other ethnic/racial group; schools reported 61-75% free/reduced lunch students. Our results indicated that each of the latent factors for the three PE components demonstrate a good fit with the data. Our results also indicated that these components loaded on to a higher-order PE factor (X2 = 32.68; df: 22; p = .07; RMSEA: 0.04; 95% CI: .00, .06; CFI: 0.99). We found that the second-order PE factor was negatively associated with aggressive behavior and positively associated with prosocial engagement. Our results suggest that empowerment-focused programs would benefit from incorporating components addressing how youth think about themselves in relation to their social contexts (intrapersonal), understanding social and material resources needed to achieve specific goals (interactional), and actions taken to influence outcomes (behavioral). Our results also suggest that integrating the three components and promoting PE may help increase likelihood of positive behaviors (e.g., prosocial involvement); we did not find an association between PE and aggressive behavior. Implications and future directions for empowerment research are discussed. PMID- 27709633 TI - What emotional tears convey: Tearful individuals are seen as warmer, but also as less competent. AB - Earlier research found that the mere sight of tears promotes the willingness to provide support to the person shedding the tears. Other research, however, found that deliberate responses towards tearful persons could be more negative as well. We think this is because tears have ambivalent effects on person perception: We predicted that tearful people are seen as warmer, but also as less competent. In three studies, we asked participants (total N = 1,042) to form their impression of someone based on a picture. The depicted person either displayed visible tears, or the tears had been digitally removed. Tearful individuals were perceived as being warmer, but also as less competent. In Study 2, we also added a measure of perceived sadness. Seeing a tearful face increased perceived sadness, and this (partially) explained the reduction in perceived competence of the target person. There was no such indirect effect of the tear on perceived warmth via perceived sadness. Study 3 found that people would be more likely to approach a tearful person to offer help than a tearless individual. At the same time, tearful individuals would be more likely to be avoided in situations in which the observer needs assistance for an important task. PMID- 27709634 TI - Occupational dermatitis in hairdressers - influence of individual and environmental factors. AB - BACKGROUND: Hairdressers are at risk of developing occupational contact dermatitis because of their intense contact with wet work in combination with chemicals. OBJECTIVES: To perform an analysis of a cohort study of hairdressers with occupational contact dermatitis recognized in the period 2006-2011, focusing on individual and environmental factors associated with the disease. METHODS: The study was a descriptive, register-based survey including all hairdressers with recognized occupational contact dermatitis in Denmark in the period January 2006 to September 2011. Data were obtained from the Danish National Board of Industrial Injuries. RESULTS: The study comprised 381 patients (373 women and 8 men). The median age was 25 years, 64.8% were apprentices, and 35.2% were fully trained hairdressers. The prevalence of atopic dermatitis was 36.0%, and was significantly higher among apprentices than among fully trained hairdressers (44.9% and 19.4%, respectively) (p < 0.001). Of the patients, 48.3% had their dermatitis recognized as occupational irritant contact dermatitis, 46.7% had their dermatitis recognized as as occupational allergic contact dermatitis or combined allergic and irritant contact dermatitis, and 5.0% were recognized as having occupational contact urticaria. CONCLUSION: The low median age, the high percentages of atopic dermatitis in apprentices and the fact that more apprentices than fully trained hairdressers had recognized occupational contact dermatitis underlines the importance of early prevention. PMID- 27709635 TI - ISO 17025 validation of a next-generation sequencing assay for relationship testing. AB - The HID-Ion AmpliSeqTM Identity Panel is a next-generation sequencing assay with 90 autosomal and 34 Y-chromosome SNPs that are amplified in one PCR step and subsequently sequenced using the Ion Personal Genome Machine (Ion PGMTM) System. This assay was validated for relationship testing in our ISO 17025 accredited laboratory in 2015. Here, the essential parts of the validation report submitted to the Danish Accreditation Fund are presented. A total of 100 unrelated Danes were typed in duplicates and the locus balance, heterozygote balance (Hb) and noise levels were analysed in detail. Two loci were disregarded for casework because genotyping was uncertain. Hb for rs7520386 was skewed and high levels of noise were observed in rs576261. Three general acceptance criteria for analysis of single-source samples were defined: (i) sequencing depth > 200 reads, (ii) noise level < 3% and (iii) Hb > 0.3. A Python script named SNPonPGM was developed to assist the analyst by highlighting loci that do not fulfil the general acceptance criteria. Furthermore, SNPonPGM has functions that reduce the hands-on time of the reporting officer to a few minutes per case. Mixtures with DNA from two individuals in a 1:24 ratio were readily identified using the three criteria and the SNPonPGM script. PMID- 27709637 TI - Arabidopsis thaliana serpins AtSRP4 and AtSRP5 negatively regulate stress-induced cell death and effector-triggered immunity induced by bacterial effector AvrRpt2. AB - Protease inhibitors and their cognate proteases regulate growth, development and defense. Serine protease inhibitors (serpins) constitute a large family of genes in most metazoans and plants. Drosophila NECROTIC (NEC) gene and its homologues in the mammalian system are well-characterized serpins, which play a role in regulating proteases that participate in cell death pathways. Although the Arabidopsis genome contains several serpin homologs, biological function is not known for most of them. Here we show that two Arabidopsis serpins, AtSRP4 and AtSRP5, are closest sequence homologue of Drosophila NEC protein, and are involved in stress-induced cell death and defense. Expression of both AtSRP4 and AtSRP5 genes induced upon ultra-violet (UV)-treatment and inoculation with avirulent pathogens. The knockout mutants and amiRNA lines of AtSRP4 and AtSRP5 exaggerated UV- and hypersensitive response (HR)-induced cell death. Over expression of AtSRP4 reduced UV- and HR-induced cell death. Mutants of AtSRP4 and AtSRP5 suppressed whereas over-expression of AtSRP4 supported the growth of bacterial pathogen Pseudomonas syringae pv. tomato DC3000 carrying the AvrRpt2 effector, but not other avirulent or virulent pathogens. Results altogether identified AtSRP4 and AtSRP5 as negative regulators of stress-induced cell death and AvrRpt2-triggered immunity; however, the influence of AtSRP4 was more prominent than AtSRP5. PMID- 27709636 TI - PTTG1IP and MAML3, novel genomewide association study genes for severity of hyperresponsiveness in adult asthma. AB - BACKGROUND: The severity of bronchial hyperresponsiveness (BHR) is a fundamental feature of asthma. The severity of BHR varies between asthmatics and is associated with lack of asthma control. The mechanisms underlying this trait are still unclear. This study aimed to identify genes associated with BHR severity, using a genomewide association study (GWAS) on the slope of BHR in adult asthmatics. METHODS: We performed a GWAS on BHR severity in adult asthmatics from the Dutch Asthma GWAS cohort (n = 650), adjusting for smoking and inhaled corticosteroid use, and verified results in three other cohorts. Furthermore, we performed eQTL and co-expression analyses in lung tissue. RESULTS: In the discovery cohort, one genomewide significant hit located in phosphodiesterase 4D, cAMP-specif (PDE4D) and 26 SNPs with P-values < 1*10-5 were found. None of our findings replicated in adult and childhood replication cohorts jointly. In adult cohorts separately, rs1344110 in pituitary tumour-transforming 1 interacting protein (PTTG1IP) and rs345983 in Mastermind-like 3 (MAML3) replicated nominally; minor alleles of rs345983 and rs1344110 were associated with less severe BHR and higher lung tissue gene expression. PTTG1IP showed significant co-expression with pituitary tumour-transforming 1, the binding factor of PTTG1lP, and with vimentin and E-cadherin1. MAML3 co-expressed significantly with Mastermind-like 2 (MAML2), both involved in Notch signalling. CONCLUSIONS: PTTG1IP and MAML3 are associated with BHR severity in adult asthma. The relevance of these genes is supported by the eQTL analyses and co-expression of PTTG1lP with vimentin and E-cadherin1, and MAML3 with MAML2. PMID- 27709638 TI - IgE-associated allergic disorders: recent advances in etiology, diagnosis, and treatment. AB - IgE-associated allergic diseases belong to the most common inflammatory conditions. Their clinical manifestation ranges from mild symptoms to life threatening episodes. Often patients experience a reduction in physical and psychologic well-being and suffer from a decreased quality of life due to disease activity. The continuously rising number of people that are affected by an allergic condition indicates an urgent need for better diagnostics and more efficient treatment options. Recent progress in the understanding of pathophysiologic mechanisms underlying IgE-associated allergic disorders has led to the identification of novel therapeutic targets and the development of drug candidates that are currently under evaluation. In this review, we highlight studies and clinical trials, which have helped to gain further insight in the etiology of IgE-associated allergic conditions as well as advances in the development of diagnostic tools and therapeutic approaches recently published in Allergy (European Journal of Allergy and Clinical Immunology). PMID- 27709639 TI - Fast and accurate determination of the relative binding affinities of small compounds to HIV-1 protease using non-equilibrium work. AB - The fast pulling ligand (FPL) out of binding cavity using non-equilibrium molecular dynamics (MD) simulations was demonstrated to be a rapid, accurate and low CPU demand method for the determination of the relative binding affinities of a large number of HIV-1 protease (PR) inhibitors. In this approach, the ligand is pulled out of the binding cavity of the protein using external harmonic forces, and the work of pulling force corresponds to the relative binding affinity of HIV 1 PR inhibitor. The correlation coefficient between the pulling work and the experimental binding free energy of R=-0.95 shows that FPL results are in good agreement with experiment. It is thus easier to rank the binding affinities of HIV-1 PR inhibitors, that have similar binding affinities because the mean error bar of pulling work amounts to deltaW=7%. The nature of binding is discovered using the FPL approach. (c) 2016 Wiley Periodicals, Inc. PMID- 27709640 TI - Distinguishing and quantifying the torquoselectivity in competitive ring-opening reactions using the stress tensor and QTAIM. AB - Currently the theories to explain and predict the classification of the electronic reorganization due to the torquoselectivity of a ring-opening reaction cannot accommodate the directional character of the reaction pathway; the torquoselectivity is a type of stereoselectivity and therefore is dependent on the pathway. Therefore, in this investigation we introduced new measures from quantum theory of atoms in molecules and the stress tensor to clearly distinguish and quantify the transition states of the inward (TSIC) and outward (TSOC) conrotations of competitive ring-opening reactions of 3-(trifluoromethyl)cyclobut 1-ene and 1-cyano-1-methylcyclobutene. We find the metallicity xi(rb ) of the ring-opening bond does not occur exactly at the transition state in agreement with transition state theory. The vector-based stress tensor response betasigma was used to distinguish the effect of the CN, CH3 , and CF3 groups on the TSIC and TSOC paths that was consistent with the ellipticity epsilon, the total local energy density H(rb ) and the stress tensor stiffness Ssigma . We determine the directional properties of the TSIC and TSOC ring-opening reactions by constructing a stress tensor UsigmaTS space with trajectories TsigmaTS (s) with length l in real space, longer l correlated with the lowest density functional theory-evaluated total energy barrier and hence will be more thermodynamically favored.

AB - WHAT IS KNOWN AND OBJECTIVE: CASE DESCRIPTION: A 74-year-old female with achondroplastic dwarfism was diagnosed with ER-, BR- and HER2- breast cancer. No guideline currently exists to direct chemotherapy dosing in this population. She received neoadjuvant chemotherapy based on body surface area utilizing actual height and weight with dose-dense doxorubicin and cyclophosphamide followed by paclitaxel with the use of granulocyte colony-stimulating factor. Satisfactory clinical response and remission were achieved, and treatment proceeded without any significant toxicity or delays. WHAT IS NEW AND CONCLUSION: In the absence of guideline recommendations, dosing chemotherapy based on actual height and weight in patients with achondroplastic dwarfism may be safe and appropriate. PMID- 27709642 TI - Nonischaemic priapism associated with selective serotonin-3 receptor antagonist. AB - Priapism is a rare but severe urological emergency of erection of penis in the absence of physical and psychological sexual stimulation. Priapism is often idiopathic and is commonly associated with medications and underlying medical or traumatic causes. In this report, we present a case of a 70-year-old White Caucasian man who developed priapism after the administration of ondansetron, which is a selective serotonin type-3 (5-HT3) receptor antagonist. This case is unique, because, to date, there are only two presented cases in literature. The objective of this case report is to highlight the importance of recognising the possibility of priapism with ondansetron because this condition is not commonly seen in clinical practice to be associated with ondansetron and may go unrecognised. Also, potential pathophysiological mechanisms involved in the development of ondansetron-induced priapism are presented.

AB - Effects of curcumin as antioxidant in extender were evaluated on freezability of buffalo spermatozoa. Semen from each of the five bulls (n = 3 replicates, six ejaculates/bull, a total of 30 ejaculates) was diluted in Tris-citric acid extender containing curcumin (0.5, 1.0, 1.5 or 2.0 mM) or control. At pre freezing and post-thawing, total antioxidant contents (MUM/L) and lipid peroxidation levels (MUM/ml) were higher (p < .05) and lower (p < .05) respectively, with 1.5 and 2.0 mM compared to 0.5 and 1.0 mM curcumin and control. At post-thawing, progressive motility (PM, %) and rapid velocity (RV, %) were higher (p < .05) with 1.5 mM compared to other doses of curcumin and control (except in case of RV, 1.5 was similar with 1.0 mM). Kinematics (average path velocity, MUm/s; straight-line velocity, MUm/s; curved-line velocity, MUm/s; straightness, %; linearity, %), in vitro longevity (%, PM and RV) and DNA integrity (%) at post-thawing were higher (p < .05) with 1.5 mM compared to control. At post-thawing, supravital plasma membrane integrity (%) and viable spermatozoa with intact acrosome (%) were higher with 1.5 compared to 2.0 mM curcumin and control. We concluded that freezability of water buffalo spermatozoa is improved with the addition of 1.5 mM curcumin in extender. PMID- 27709644 TI - A case of hypopituitarism accompanying Kearns-Sayre syndrome treated with human chorionic gonadotropin: A case report and literature review. AB - Kearns-Sayre syndrome (KSS) is a disorder caused by mutations in mitochondrial DNA. Here, we report an unusual case of Kearns-Sayre syndrome accompanied by hypopituitarism (deficiencies in reproductive and growth hormones). A 20-year-old male presented with growth retardation for the last 8 years, as well as the following findings: short stature, delayed puberty, myasthenia, an extraocular movement deficit, drooping eyelids, pectus carinatum and scoliosis. Cerebral enhanced magnetic resonance imaging revealed dysplasias of the pituitary, white matter and cerebellum. Laboratory work-up showed subnormal testosterone and growth hormone levels, a subnormal testicular volume, sensorineural deafness, pigmentary retinopathy, complete right bundle branch block and left anterior bundle branch block. Pathological examination revealed ragged red muscle fibres. Thus, this rare case involved the coexistence of Kearns-Sayre syndrome and hypopituitarism in a patient. Administration of coenzyme Q10 for the KSS and hormone replacement therapy for the endocrinopathies were performed for treatment of this patient. PMID- 27709646 TI - Multiple program/multiple data molecular dynamics method with multiple time step integrator for large biological systems. AB - Parallelization of molecular dynamics (MD) simulation is essential for investigating conformational dynamics of large biological systems, such as ribosomes, viruses, and multiple proteins in cellular environments. To improve efficiency in the parallel computation, we have to reduce the amount of data transfer between processors by introducing domain decomposition schemes. Also, it is important to optimize the computational balance between real-space non-bonded interactions and reciprocal-space interactions for long-range electrostatic interactions. Here, we introduce a novel parallelization scheme for large-scale MD simulations on massively parallel supercomputers consisting of only CPUs. We make use of a multiple program/multiple data (MPMD) approach for separating the real-space and reciprocal-space computations on different processors. We also utilize the r-RESPA multiple time step integrator on the framework of the MPMD approach in an efficient way: when the reciprocal-space computations are skipped in r-RESPA, processors assigned for them are utilized for half of the real-space computations. The new scheme allows us to use twice as many as processors that are available in the conventional single program approach. The best performances of all-atom MD simulations for 1 million (STMV), 8.5 million (8_STMV), and 28.8 million (27_STMV) atom systems on K computer are 65, 36, and 24 ns/day, respectively. The MPMD scheme can accelerate 23.4, 10.2, and 9.2 ns/day from the maximum performance of single-program approach for STMV, 8_STMV, and 27_STMV systems, respectively, which correspond to 57%, 39%, and 60% speed up. This suggests significant speedups by increasing the number of processors without losing parallel computational efficiency. (c) 2016 Wiley Periodicals, Inc. PMID- 27709645 TI - Selective plasma exchange can reduce auto-antibodies in patients with bullous pemphigoid without affecting factor XIII and fibrinogen. AB - Bullous pemphigoid (BP) is an autoimmune blistering skin disorder characterized by circulating serum IgG antibodies against two hemidesmosomal proteins: BP180 and BP230. Fundamentally, immunosuppressive therapies are administered to treat this disease, but plasmapheresis can be added for refractory patients. We experienced the case of a 63-year-old patient with refractory BP for which we administered double filtration plasmapheresis (DFPP). His skin lesions improved along with decreased IgG BP180 antibodies, but factor XIII (FXIII) and fibrinogen were also reduced by DFPP repetition. Reportedly, deficiency of those factors can cause lethal bleeding. Especially, decreased FXIII cannot be detected by prolongation of bleeding or coagulation time. To prevent further reduction of those factors and bleeding complications, DFPP was switched to selective plasma exchange (SePE), a new modality of plasmapheresis that uses a membrane plasma separator with smaller than ordinary pores. SePE further reduced pathogenic IgG BP180 antibodies, but FXIII and fibrinogen recovered. For this case, we measured the mean of reduction ratios in serum IgG and FXIII both before and after plasmapheresis sessions and detected the decreased levels of FXIII and fibrinogen during DFPP. We were able to switch to SePE from DFPP appropriately before any bleeding event occurred. The utility of SePE was demonstrated, especially for the reduction of pathogenic antibodies with retention of FXIII and fibrinogen, which have the longest half-lives among coagulation factors and which take a long time to recover. PMID- 27709647 TI - Multi-drug-resistant Acinetobacter calcoaceticus-Acinetobacter baumannii complex infection outbreak in dogs and cats in a veterinary hospital. AB - BACKGROUND: Members of the Acinetobacter calcoaceticus-Acinetobacter baumannii complex cause severe outbreaks in humans, and are increasingly reported in animals. OBJECTIVE AND METHODS: A retrospective study, describing a severe outbreak in dogs and cats caused by a multidrug resistant member of the Acinetobacter calcoaceticus-Acinetobacter baumannii complex in a veterinary hospital, between July 2010 and November 2012. RESULTS: The study included 19 dogs and 4 cats. Acinetobacter calcoaceticus-Acinetobacter baumannii complex bacteria were isolated from urine (9 animals), respiratory tract (11), tissues (3) and blood (1). The most common infection-associated findings included fever, purulent discharge from endotracheal tubes, hypotension, and neutropaenia. Infections led to pneumonia, urinary tract infection, cellulitis and sepsis. Infection was transmitted in the intensive care unit, where 22 of 23 animals were initially hospitalised. The mortality rate was 70% (16 of 23 animals), and was higher in cases of respiratory infection compared to other infections. Aggressive environmental cleaning and disinfection, with staff education for personal hygiene and antisepsis, sharply decreased the infection incidence. CLINICAL SIGNIFICANCE: Health care-associated outbreaks with multidrug resistant Acinetobacter calcoaceticus-Acinetobacter baumannii complex in dogs and cats are potentially highly fatal and difficult to eradicate, warranting monitoring, antiseptic techniques and judicious antibiotic use. PMID- 27709648 TI - Headless spermatozoa in infertile men. AB - Spermatozoa morphology, an important parameter in a semen specimen's potential fertility evaluation, is a significant factor for in vitro fertilisation in assisted reproductive technology. Eleven sterile men with headless spermatozoa, a type of human teratozoospermia, are presented. Their ejaculates' headless spermatozoa percentages were high with rare normal spermatozoa forms. Additionally, abnormal morphology (e.g. round-headed or microcephalic spermatozoa) was also found. Spermatozoa motility was somewhat affected, potentially because of the missing mitochondrial sheath at the sperm tail base. Patients who underwent assisted reproductive technology treatment experienced adverse pregnancy outcomes. Work types and corresponding environments seemed irrelevant, but specific family history may have prompted its genetic origin. Computer-assisted semen analysis systems easily mistake headless spermatozoa as oligozoospermia because of nonrecognition of the loose head. However, morphological testing, especially with an electronic microscope, clearly identifies abnormal spermatozoa. Future exploration requires more methods investigating the frequency and percentage of this morphological abnormality in different populations with varied fertility levels. Such research would estimate the probable correlation of the abnormality with other semen parameters and examine the potential developmental or genetic origins. During clinical work, medical staff should detect these cases, avoid misdiagnosis and provide proper consultation about diagnosis and assisted reproductive technology treatment. PMID- 27709649 TI - Histological alterations in Leydig cells and macrophages in azoospermic men. AB - The study aimed to compare the histological features of Leydig cells and macrophages in the testicular interstitium of obstructive versus nonobstructive azoospermia. Thirty-nine azoospermic men undergoing testicular sperm extraction during intracytoplasmic sperm injection were allocated into obstructive azoospermia group (GI) and nonobstructive azoospermia group (GII) which was subdivided into Sertoli cell-only syndrome (GIIA), germ cell arrest (GIIB) and hypospermatogenesis (GIIC) subgroups. Serum LH, FSH and testosterone levels were measured. Ultrastructural changes and the mean number of CD68-positive cells were estimated in the different groups. In GIIA, Leydig cells' processes came in contact with macrophages and showed smooth endoplasmic reticulum dilatation. In GIIB, Leydig cells showed apoptotic changes. Macrophages were commonly encountered in their vicinity demonstrating large number of lysosomes. In GIIC, Leydig cells showed euchromatic nuclei. Macrophages showed expulsion of their lysosomal contents in the interstitium surrounded by apoptotic bodies. The mean count of total CD68-positive macrophages was higher in cases of obstructive azoospermia with nonsignificant differences compared to nonobstructive azoospermia groups. Significant increase in FSH level was detected in GIIA compared to GI. It is concluded that structural interactions might take place between Leydig cells and macrophages in the interstitial tissue of azoospermic men. PMID- 27709650 TI - Inflammatory and anti-inflammatory cytokines in the seminal plasma of infertile men suffering from varicocele. AB - Varicocele is one of causes of the declined sperm quality and low sperm production, which can lead to infertility in males. There are several experimental and epidemiological findings which support the idea that inflammatory mechanisms play an essential role in varicocele pathogenesis. Besides, in this pathological state, interleukin-37 (IL-37) as an anti inflammatory cytokine is able to bind interleukin-18-binding protein (IL-18BP), and subsequently binds IL-18 receptor beta, inhibiting the pro-inflammatory activity of IL-18. To explore the interaction between IL-37 and IL-18 in infertility, we measured the amount of these cytokines in the seminal fluid of infertile men affected by varicocele. The seminal plasma levels of IL-37 and IL 18 were measured in 75 infertile men with varicocele and 75 healthy fertile controls (age range, 30-48 years) using enzyme-linked immunosorbent assay. The seminal levels of IL-37 and IL-18 were significantly increased in infertile men with varicocele when compared to fertile controls (p < .0001). Because of the essential role(s) of cytokines in inflammatory response of cell systems, it could be possible that sperm motility is reduced following increased IL-18, activated neutrophils and reactive oxygen species in semen of infertile patients with varicocele. Moreover, the results of this study indicated that interaction between IL-37 and IL-18Rbeta can lead to reduced inflammatory responses. It seems that IL-37 might be a potential biomarker and therapeutic target for male infertility. PMID- 27709651 TI - Epididymal leiomyoma: a benign intrascrotal tumour. AB - Physicians will be rarely confronted with epididymal tumours. These represent only 5% of intrascrotal tumours and are mostly (75%) benign. We report the case of a 50-year-old white male who was presented with a 5-year history of a slow growing, left scrotal mass, noted through self-examination. Ultrasound study of the scrotum identified a well-circumscribed paratesticular mass. On inguinal surgical exploration, a solid, encapsulated, grey-white mass at the tail of the left epididymis was identified and excised, with intra-operative pathological consultation showing no signs of malignancy. The diagnosis of an epididymal leiomyoma was determined through subsequent immune-histopathological analysis. Diagnostic steps preceding operative exploration of a paratesticular, epididymal tumour are briefly analysed and physicians are encouraged to avoid a radical approach, without prior pathological consultation. Epididymal leiomyomas are benign tumours that can be cured through simple, organ-preserving surgical excision. PMID- 27709652 TI - Circulating Epstein-Barr virus-encoded micro-RNAs as potential biomarkers for nasal natural killer/T-cell lymphoma. AB - Nasal natural killer/T-cell lymphoma (NNKTL) is an Epstein-Barr virus (EBV) associated malignancy and is characterized by local invasion and widespread dissemination, with a consequent poor prognosis. Micro-RNAs (miRNAs) play roles in the pathogenesis of several malignancies by regulating gene expression and have been recently identified as stable entities in serum. Here, we investigated the value of circulating EBV-miRNAs as biomarkers for NNKTL. Sera of patients with NNKTL were subjected to miRNA polymerase chain reaction (PCR)-array analysis, after which serum EBV-miRNA levels were verified using quantitative PCR. The latter analysis revealed high miR-BART2-5p, miR-BART7-3p, miR-BART13-3p, and miR-BART1-5p expression levels in sera of patients with NNKTL and indicated accurate values for discriminating patients with NNKTL from healthy controls. Levels of these 4 EBV-miRNAs, which were secreted from NNKTL cells, significantly decreased after treatment compared with those before treatment. Furthermore, a high circulating miR-BART2-5p level was associated with disease progression and poor prognosis in patients with NNKTL. Our findings demonstrate that circulating EBV-miRNAs, particularly miR-BART2-5p, may serve as potential diagnostic and prognostic biomarkers in patients with NNKTL. PMID- 27709653 TI - Use of the ages and stages questionnaire adapted for South Africa and Zambia. AB - BACKGROUND: There are few readily available, relatively easy to use and culturally adaptable developmental assessment tools for young children in southern Africa. The overarching aim of this study is to test the psychometric properties, contextual appropriateness and cut-off scores across 21 age groups of the Ages and Stages Questionnaire Third Edition (Squires & Bricker, ) among a group of typically developing children in South Africa and Zambia through a combination of both caregiver-report and direct observations, and to compare children's performance across sociodemographic variables. METHODS: The sample consisted of 853 children (50.5% Zambia, with 50.1% girls for Zambia and 50% girls for South Africa) aged 2 months to 60 months. Information on caregiver employment, education and household assets were also obtained. RESULTS: The psychometric properties of the ASQ-3 in southern Africa are consistent with those found in the extant literature. Analysis of item difficulty at each age reveals adequate levels of difficulty for majority of the items, with exception of the problem solving domain where half of the items at 54 and 60 months have poor pass rates. Sociodemographic variables were significantly associated with children's performance: higher caregiver levels of education are associated with higher toddler scores on the personal-social domain and higher preschooler scores on the problem solving domain; children whose caregivers earn a salary have higher fine motor scores during toddlerhood and higher problem solving scores during preschool and children who attend preschools have higher gross motor scores during toddlerhood and higher fine motor scores during the preschool years. CONCLUSIONS: Findings provide evidence to support the psychometric properties and feasibility of using the ASQ-3 in both South Africa and Zambia through a combination of caregiver-report and direct observations. PMID- 27709654 TI - Coconut oil induced production of a surfactant-compatible lipase from Aspergillus tamarii under submerged fermentation. AB - Filamentous fungi are efficient producers of lipases. The present study focuses on identification of a potent lipolytic fungus and enhancement of lipase production through optimization of nutritional and cultural conditions under submerged fermentation. Molecular characterization of the fungus by 18S rDNA sequencing revealed its identity as Aspergillus tamarii with 98% homology. Maximum lipase production was noted in mineral salts medium supplemented with coconut oil (2.5%, v/v). A combination of ammonium chloride (2%, w/v) and tryptone (2%, w/v) facilitated maximum lipase production at pH 5 of the production medium. A carbon: nitrogen ratio of 1:4 led to significant (p < 0.00008) increase in the enzyme production in the presence of surfactant cetyltrimethylammonium bromide (0.5%, w/v). Maximum lipase activity (2,32,500 +/- 192 U/ml/min) was recorded after 7 days of incubation at 25 degrees C on a rotary shaker at 120 rpm. A 9.8-fold increase in lipase activity was recorded after optimization of the process parameters. Addition of crude lipase enhanced the oil stain removal activity of a commercially available detergent by 2.2-fold. The current findings suggest the potentiality of this fungal lipase to be used in detergent formulation. PMID- 27709655 TI - Elevated serum homocysteine level as an independent risk factor for erectile dysfunction: a prospective pilot case-control study. AB - Homocysteine is an amino acid that is produced from the metabolic demethylation of dietary methionine. It has gained arising attention for its association with increased risk of myocardial infarction, stroke and venous thromboembolism. Erectile dysfunction (ED), especially for vasculogenic ED, is a vascular disorder of cavernosal vascular bed. In this prospective pilot case-control study, we investigated plasma homocysteine levels in 32 ED patients and 20 healthy control men. Related patients characteristics including age, weight, height, marital status, smoking and drinking status, level of education were collected and analysed as well as penile colour Doppler ultrasound parameters. ED patients were further categorised into mild, moderate and severe ED based on 5-item of the International Index of Erectile Function. Higher homocysteine levels were observed in ED patients as compared with controls (p < .05). A multivariate logistic regression with likelihood ratio test revealed that homocysteine and penile peak systolic blood flow velocity (PSV) levels posed significant indicators for ED (chi-square of likelihood ratio = 20.42, df = 2, p < .005) as well as moderate and severe ED occurrence (chi-square of likelihood ratio = 28.50, df = 2, p < .005). The threshold value of homocysteine concentration to discriminate ED and control subjects was 12.65 MUmol/L by performing receiver operating characteristic curve analyses. These data suggested that elevation of homocysteine levels was associated with an increased risk of ED.

This commentary provides feedback on a previously proposed approach for predicting clinically relevant interactions with grapefruit juice based on the average inherent oral bioavailability (F) and magnitude of increase in bioavailability with other CYP3A inhibitors of the drug. COMMENT: Additional factors such as variability of the magnitude of the pharmacokinetic interaction among individuals, product monograph cautionary statements and vulnerability of the patient population should be considered. WHAT IS NEW AND CONCLUSION: A flow diagram is provided that should improve prediction of the pharmacokinetic interaction and clinical relevance for affected drugs and that recommends different courses of action for patient management. Forecasting the clinical importance of a particular drug interaction with grapefruit can be improved through consideration of additional readily available drug regulatory information.

PMID- 27709659 TI - Human immunodeficiency virus associated thrombotic thrombocytopenic purpura, a clinical conundrum. AB - HIV complicates the diagnostic and therapeutic approaches to idiopathic thrombotic thrombocytopenic purpura (TTP), prompting debate in the literature regarding the benefit of plasma exchange versus simple plasma infusion. Herein we present a case of HIV-TTP, initially treated conservatively with plasma infusion but because of progressive neurologic decline, required urgent plasma exchange for resolution of hematologic derangements and neurologic sequelae. Based on the available literature, there appears to be a spectrum of HIV-associated TTP disorders. Patients with advanced HIV disease and opportunistic infections who present with thrombotic microangiopathy tend to respond to simple plasma infusion, while patients with less progressive HIV disease tend to behave like those with idiopathic TTP, requiring plasma exchange rather than simple plasma infusion. This article illustrates that in patients with HIV-TTP who do not respond to plasma infusion, early escalation to plasma exchange may help avoid life-threatening complications such as seizures and even death.

AB - OBJECTIVE: To investigate the prevalence of self-reported edentulism and its associated risk factors among community-dwelling adults aged 45 years and older in China. MATERIALS AND METHODS: Data from the national baseline survey (2011 2012) of the China Health and Retirement Longitudinal Study (CHARLS) were used for this study (N = 17 167). Bivariate and multivariate logistic regressions were conducted to assess the predictors of edentulism. Models 1 and 2 were based on the whole sample. Models 3 and 4 were based on the subsample (N = 9933) from whom anthropometric and blood biomarker data were available. RESULTS: The prevalence of edentulism was 8.64% among Chinese adults aged 45 and above. As shown by Model 1, older age was a robust predictor for edentulism (odds ratio [OR] = 3.81 for people aged 55-64; OR = 11.22 for people aged 65-74; OR = 24.05 for people aged 75 and above). Other factors positively associated with edentulism included being female (OR = 1.25), rural residence (OR = 1.30), asthma (OR = 1.48), depression (OR = 1.20), reduced physical function (OR = 1.37) and current smoking status (OR = 1.36). People with higher educational levels (OR = 0.75 for people who can read and write; OR = 0.64 for people who obtained a junior high school education or above) and better-off economic status (OR = 0.80) were less likely to be edentate. The association between edentulism and age, educational level, economic status and physical function remained significant in Model 3, and in addition, being underweight appeared as another strong predictor (OR = 1.93). CONCLUSIONS: The estimated prevalence of edentulism and the identified associated factors will provide epidemiologic evidence for future research and interventions in the target population in China.

PMID- 27709663 TI - The MAPT gene is differentially methylated in the progressive supranuclear palsy brain. AB - BACKGROUND: Progressive supranuclear palsy (PSP) is a rare neurodegenerative disease causing parkinsonian symptoms. Altered DNA methylation of the microtubule associated protein tau gene correlates with the expression changes in Alzheimer's disease and Parkinson's disease brains. However, few studies examine the sequences beyond the constitutive promoter. OBJECTIVES: Because activating different microtubule-associated protein tau gene control regions via methylation might regulate the differential tau expression constituting the specific signatures of individual tauopathies, we compared methylation of a candidate promoter, intron 0. METHODS: We assessed DNA methylation in the brains of patients with different tauopathies (35 Alzheimer's disease, 10 corticobasal degeneration, and 18 PSP) and 19 controls by intron 0 pyrosequencing. We also evaluated methylation in an independent cohort of 11 PSP cases and 12 controls. Frontal (affected by tau pathology) and occipital (unaffected) cortices were analyzed. RESULTS: In the initial samples, one CpG island site in intron 0 (CpG1) showed significant hypomethylation in PSP-affected frontal cortices when compared with controls (P = .022). Such hypomethylation was observed in replicate samples, but not in occipital cortices or other tauopathies. PSP and control samples (combining the initial and replicate samples) remained significantly different after adjustment for potential confounding factors (age, H1/H1 diplotype; P = .0005). PSP-affected tissues exhibited microtubule-associated protein tau RNA hyperexpression when compared with controls (P = .004), although no correlation with CpG1 methylation was observed. CONCLUSIONS: This exploratory study suggests that regions other than the constitutive promoter may be involved in microtubule associated protein tau gene regulation in tauopathies and that intron 0 hypomethylation may be a specific epigenetic signature of PSP. These preliminary findings require confirmation. (c) 2016 International Parkinson and Movement Disorder Society. PMID- 27709664 TI - Validation rules for blood smear revision after automated hematological testing using Mindray CAL-8000. AB - BACKGROUND: This article was aimed to test the use of validation rules for blood smear review after automated hematological testing using Mindray CAL-8000 (two hematological analyzers and one autoslider). METHODS: This study was based on 1013 peripheral blood samples (PB) referred for routine hematological testing. Results of testing on CAL-8000 were analyzed using both locally derived and International Consensus Group for Hematology (ICGH) validation rules, and then compared with data obtained by optical microscopy (OM). A workflow analysis was also completed. RESULTS: The overall agreement with locally derived and ICGH criteria was 91% and 85%, but a higher sensitivity was observed for locally derived criteria (0.97 vs 0.95). The percentage of false negative and false positive samples was 2.1% and 7.1% using ICGH criteria, and was 1.4% and 14% using locally defined rules. The throughput of CAL-8000 system was 208 samples/h, with a percentage of OM analysis comprised between 14% and 17%, and sensitivity of 0.97. As regards personnel activity, we estimated 0.8 full-time equivalent (FTE) of technical staff and 0.7 FTE of personnel for clinical validation of data and blood smear review. CONCLUSION: These results show that customization of validation rules is necessary for enhancing the quality of hematological testing and optimizing workflow.

AB - BACKGROUND: Microelectrode recordings along preplanned trajectories are often used for accurate definition of the subthalamic nucleus (STN) borders during deep brain stimulation (DBS) surgery for Parkinson's disease. Usually, the demarcation of the STN borders is performed manually by a neurophysiologist. The exact detection of the borders is difficult, especially detecting the transition between the STN and the substantia nigra pars reticulata. Consequently, demarcation may be inaccurate, leading to suboptimal location of the DBS lead and inadequate clinical outcomes. METHODS: We present machine-learning classification procedures that use microelectrode recording power spectra and allow for real time, high-accuracy discrimination between the STN and substantia nigra pars reticulata. RESULTS: A support vector machine procedure was tested on microelectrode recordings from 58 trajectories that included both STN and substantia nigra pars reticulata that achieved a 97.6% consistency with human expert classification (evaluated by 10-fold cross-validation). We used the same data set as a training set to find the optimal parameters for a hidden Markov model using both microelectrode recording features and trajectory history to enable real-time classification of the ventral STN border (STN exit). Seventy three additional trajectories were used to test the reliability of the learned statistical model in identifying the exit from the STN. The hidden Markov model procedure identified the STN exit with an error of 0.04 +/- 0.18 mm and detection reliability (error < 1 mm) of 94%. CONCLUSIONS: The results indicate that robust, accurate, and automatic real-time electrophysiological detection of the ventral STN border is feasible.

AB - BACKGROUND: The aim of this study was to determine the hematologic parameter with the highest diagnostic differentiation in the identification of massive acute pulmonary embolism (APE). METHODS: A retrospective study was performed on patients diagnosing with APE between June 2014 and June 2016. All radiological and laboratory parameters of patients were scanned through the electronic information management system of the hospital. PLR was obtained from the ratio of platelet count to lymphocyte count, NLR was obtained from the ratio of neutrophil count to lymphocyte count, WMR was obtained from white blood cell in mean platelet volume ratio, MPR was obtained from the ratio of mean platelet volume to platelet count, and RPR was obtained from the ratio of red distribution width to platelet count. RESULTS: Six hundred and thirty-nine patients consisting of 292 males (45.7%) and 347 females (54.3%) were included in the research. Independent predictors of massive risk as compared to sub-massive group were; pulmonary arterial systolic pressure (PASP) (OR=1.40; P=.001), PLR (OR=1.59; P<.001), NLR (OR=2.22; P<.001), WMR (OR=1.22; P<.001), MPR (OR=0.33; P<.001), and RPR (OR=0.68; P<.001). Upon evaluation of the diagnostic differentiation of these risk factors for massive APE by employing receiver operating characteristic curve analysis, it was determined that PLR (AUC+/-SE=0.877+/-0.015; P<.001), and NLR (AUC+/-SE=0.893+/-0.013; P<.001) have similar diagnostic differentiation in diagnosing massive APE and these two parameters are superior over PASP, MPR, WMR, and RPR. CONCLUSION: We determined that the levels of NLR and PLR are superior to other parameters in the determination of clinical severity in APE cases. PMID- 27709686 TI - Perioperative mortality is the Achilles heel for cardiac transplantation in adults with congenital heart disease: Evidence from analysis of the UNOS registry. AB - BACKGROUND: Adults with congenital heart disease may present with end-stage heart failure necessitating orthotopic heart transplant (OHT). We sought to review the United Network for Organ Sharing (UNOS) experience with this unique cohort focusing on surgical outcomes and survival. METHODS: From the UNOS registry, 737 adult congenital heart disease recipients (ACHDR) out of 26,993 OHT patients (2.7%) who underwent OHT were studied to analyze early and late outcomes and compared to non-congenital recipients (NCR) over a 15-year period (2000-2014). RESULTS: More ACHDR underwent OHT in the recent-era (3.1%; 2010-2014) as compared to the initial-era (2.5%; 2000-2004; p = 0.03). ACHDR were more likely female (40% vs. 24%; p < 0.01), younger (35 vs. 53 years; p < 0.01), less likely to have ventricular assist devices (4.2% vs. 19.3%; p < 0.01), more likely to have class II panel-reactive antibody >10%; p < 0.01, and were listed for a longer time (249 vs. 181 days; p < 0.01). When compared to the NCR in the same period, the ACHDR cohort had longer postoperative length of stay (27 vs. 20 days; p < 0.01), higher operative mortality (11.5% vs. 4.6% p < 0.001), higher incidence of primary graft dysfunction (4.3% vs. 2.6%; p < 0.01), and higher need for dialysis (20% vs. 9%; p < 0.01). Primary graft dysfunction is the most common cause of death in (5.8%) ACHDR. Although short-term survival is poorer, long-term survival of ACHDR was found to be equivalent or better than NCR in long term. CONCLUSIONS: Perioperative morbidity and mortality adversely affects short-term survival in ACHDR. ACHDR who survive the first post-transplant year have equivalent or better long-term survival than NCR. PMID- 27709685 TI - Study of LRRK2 variation in tauopathy: Progressive supranuclear palsy and corticobasal degeneration. AB - BACKGROUND: Mutations in the leucine-rich repeat kinase 2 gene (LRRK2) are the most common genetic cause of Parkinson's disease (PD). Unexpectedly, tau pathology has been reported in a subset of LRRK2 mutation carriers. METHODS: To estimate the frequency of pathogenic LRRK2 mutations and to evaluate the association of common LRRK2 variants with risk of primary tauopathies, we studied 1039 progressive supranuclear palsy (PSP) and 145 corticobasal degeneration patients from the Mayo Clinic Florida brain bank and 1790 controls ascertained at Mayo Clinic. Sanger sequencing of LRRK2 exons 30, 31, 35, and 41 was performed in all patients, and genotyping of all 17 known exonic variants with minor allele frequency >0.5% was performed in patients and controls. RESULTS: LRRK2 mutational screening identified 2 known pathogenic mutations (p.G2019S and p.R1441C), each in 1 PSP patient, the novel p.A1413T mutation in a PSP patient and the rare p.R1707K mutation in a corticobasal degeneration patient. Both p.A1413T and p.R1707K mutations were predicted damaging by at least 2 of 3 prediction programs and affect evolutionary conserved sites of LRRK2. Association analysis using common LRRK2 variants only showed nominal association of the p.L153L variant with PSP. CONCLUSIONS: Our study confirms the presence of pathogenic and potentially pathogenic LRRK2 mutations in pathologically confirmed primary tauopathies, albeit with low frequency. In contrast to PD, common LRRK2 variants do not appear to play a major role in determining PSP and corticobasal degeneration risk. (c) 2016 International Parkinson and Movement Disorder Society.

AB - Herein, we report two new types of twisted polycyclic arenes (2 a, b and 3 a, b) with constitutionally isomeric pi-backbones, which are synthesized by controlling the Scholl reaction of 1,2,4,5-tetra(naphth-2-yl)-3,6-diphenylbenzene (1) with properly positioned electron-donating substituents. With a polycyclic backbone containing two [5]helicene and four [4]helicene moieties, 2 a and b are new members of multiple helicenes with interesting stereochemistries. The as synthesized 2 a and b are the twisted isomers, and thermal isomerization of twisted-2 b results in anti-2 b, a more stable stereoisomer. Both twisted- and anti-2 b have been fully characterized, and the thermal isomerization of twisted 2 b has been studied with 1 H NMR spectroscopy and DFT calculations. Compounds 3 a and b are new members of twistacenes, the benzannulated pentacene backbone of which exhibits an end-to-end twist as found from the crystal structure. Twisted- and anti-2 b are also found to function as p-type semiconductors in solution processed thin film transistors, whereas the thin films of 3 b appear insulating presumably due to the lack of pi-pi interactions. PMID- 27709689 TI - Torsional and Electronic Factors Control the C-H???O Interaction. AB - The precise role of non-conventional hydrogen bonds such as the C-H???O interaction in influencing the conformation of small molecules remains unresolved. Here we survey a series of beta-turn mimetics using X-ray crystallography and NMR spectroscopy in conjunction with quantum calculation, and conclude that favourable torsional and electronic effects are important for the population of states with conformationally influential C-H???O interactions. Our results also highlight the challenge in attempting to deconvolute a myriad of interdependent noncovalent interactions in order to focus on the contribution of a single one. Within a small molecule that is designed to resemble the complexity of the environment within peptides and proteins, the interplay of different steric burdens, hydrogen-acceptor/-donor properties and rotational profiles illustrate why unambiguous conclusions based solely on NMR chemical shift data are extremely challenging to rationalize. PMID- 27709690 TI - Weekend days are not required to accurately measure oral intake in hospitalised patients. AB - BACKGROUND: Nutrition studies in patients admitted to hospital frequently disregard oral intake because measurement is time-intensive and logistically challenging. In free-living populations, weighed food records (WFR) are the gold standard and are conducted on weekend and weekdays to capture variations in intake, although this may not translate during hospitalisation. The present study aimed to determine whether oral intake differs between weekends and weekdays in hospitalised patients. METHODS: For adult patients initially admitted to the intensive therapy unit with a moderate-severe head injury over a 12-month period, WFR were conducted each week on Tuesday, Thursday and Saturday throughout hospitalisation. Meal components were weighed before and after consumption, and energy and protein intakes were calculated using specialised software. Data are reported as the mean (SD). Differences were assessed using paired t-tests and agreement using Bland-Altman plots. RESULTS: Thirty-two patients had WFR collected on 220 days, 68% (n = 149) on weekdays and 32% (n = 71) on weekends. Overall, daily intakes were 5.72 (3.67) MJ [1367 (877) kcal] and 62 (40) g protein. There were no differences in intake across all days (P = 0.937 energy, P = 0.797 protein), nor between weekdays and weekends, in weeks 1-3 of oral intake (all P > 0.1). Limits of agreement between mean intakes across days were wide for energy [range -11.20 to 9.55 MJ (-2680 to 2283 kcal)] and protein (range -125 to 110 g). CONCLUSIONS: Grouped energy and protein intakes from WFR in hospitalised patients are similar on weekdays and weekends, although large intra-patient variations occur. Future quantification of oral intake during hospitalisation should include as many days as feasible, although not necessarily weekend days, to reflect true intake.

AB - INTRODUCTION AND AIMS: Intimate partner violence (IPV) perpetration is common among men who use substances. Substance use is a contributing factor for IPV perpetration. This cross-sectional study determined lifetime prevalence and factors associated with ever perpetrating IPV by men receiving substance use treatment in Brazil (n = 281) and England (n = 223). DESIGN AND METHODS: IPV, adverse childhood experiences, attitudes towards gender relations and roles, current health state, substance use, depressive symptoms and anger expression were assessed. Logistic regression determined factors associated with ever perpetrating any (emotional, physical and/or sexual) IPV. Multinomial logistic regression determined factors associated with ever perpetrating different types of IPV. RESULTS: 74.6% (373/500) reported ever perpetrating IPV: 16.5% (82/498) emotional IPV only, 46.4% (231/498) physical IPV (with/without emotional IPV) and 11.6% (58/498) sexual IPV (with/without emotional and/or physical IPV). Higher anger expression, higher depressive symptoms, fighting physically with another man in the past year (Brazil only), experiencing a greater number of adverse childhood experiences and a higher hazardous drinking score (England only) predicted ever perpetrating IPV. Compared to never perpetrating any IPV, anger expression was associated with emotional and physical IPV perpetration; fighting physically with another man in the past year was associated with physical IPV perpetration and experiencing a greater number of adverse childhood experiences and a higher hazardous drinking score were associated with both physical and sexual IPV perpetration. DISCUSSION AND CONCLUSIONS: Integrated interventions that address IPV and substance use delivered in substance use treatment could improve outcomes for perpetrators and victims.[Gilchrist G, Radcliffe P, Noto AR, d'Oliveira AFPL.

AB - BACKGROUND: Vegetarian diets may be associated with certain benefits toward human health, although current evidence is scarce and contrasting. In the present study, a systematic review and meta-analysis of prospective cohort studies was performed with respect to the association between vegetarian diets and breast, colorectal and prostate cancer risk. METHODS: Studies were systematically searched in Pubmed and EMBASE electronic databases. Eligible studies had a prospective design and compared vegetarian, semi- and pesco-vegetarian diets with a non-vegetarian diet. Random-effects models were applied to calculate relative risks (RRs) of cancer between diets. Statistical heterogeneity and publication bias were explored. RESULTS: A total of nine studies were included in the meta analysis. Studies were conducted on six cohorts accounting for 686 629 individuals, and 3441, 4062 and 1935 cases of breast, colorectal and prostate cancer, respectively. None of the analyses showed a significant association of vegetarian diet and a lower risk of either breast, colorectal, and prostate cancer compared to a non-vegetarian diet. By contrast, a lower risk of colorectal cancer was associated with a semi-vegetarian diet (RR = 0.86, 95% confidence interval = 0.79-0.94; I2 = 0%, Pheterogeneity = 0.82) and a pesco-vegetarian diet (RR = 0.67, 95% confidence interval = 0.53, 0.83; I2 = 0%, Pheterogeneity = 0.46) compared to a non-vegetarian diet. The subgroup analysis by cancer localisation showed no differences in summary risk estimates between colon and rectal cancer. CONCLUSIONS: A summary of the existing evidence from cohort studies on vegetarian diets showed that complete exclusion of any source of protein from the diet is not associated with further benefits for human health.

AB - A novel luminescent microporous lanthanide metal-organic framework (Ln-MOF) based on a urea-containing ligand has been successfully assembled. Structural analysis revealed that the framework features two types of 1D channels, with urea N-H bonds projecting into the pores. Luminescence studies have revealed that the Ln MOF exhibits high sensitivity, good selectivity, and a fast luminescence quenching response towards Fe3+ , CrVI anions, and picric acid. In particular, in the detection of Cr2 O72- and picric acid, the Ln-MOF can be simply and quickly regenerated, thus exhibiting excellent recyclability. To the best of our knowledge, this is the first example of a multi-responsive luminescent Ln-MOF sensor for Fe3+ , CrVI anions, and picric acid based on a urea derivative. This Ln-MOF may potentially be used as a multi-responsive regenerable luminescent sensor for the quantitative detection of toxic and harmful substances. PMID- 27709696 TI - The effect of lipid extraction on carbon and nitrogen stable isotope ratios in oyster tissues: Implications for glycogen-rich species. AB - RATIONALE: Extraction of lipids from tissues prior to carbon stable isotope analysis (SIA) has become a common practice, despite a lack of species-specific data to indicate when lipid extraction is needed. Marine invertebrates, including bivalves, are known to store carbon as glycogen and less in the form of lipids than other species, potentially reducing the need for lipid extraction even when C:N values are above 3.5, a value that previous studies suggest indicates a need for lipid extraction of animal tissues. METHODS: We investigated the need for lipid extraction on individual tissues (adductor muscle, gut gland, gill) and whole tissue of a glycogen-storing species, the oyster Crassostrea virginica. Bulk and lipid-extracted samples were analyzed for their C and N stable isotope ratios by continuous flow isotope ratio mass spectrometry (IRMS). Samples were analyzed on a 20-20 isotope ratio mass spectrometer (PDZ Europa) after combustion in an elemental analyzer (PDZ Europa Automatic Analyzer-Gas Solid Liquid). RESULTS: Although the C:N values for most bulk (unextracted) tissue samples were greater than 3.5, the lipid-extracted delta13 C values did not differ from the bulk values. Lipid extraction, however, affected delta15 N values in all tissue types except adductor muscle, indicating that separate SIA may be required when tissues are lipid extracted. CONCLUSIONS: These data demonstrate that it is not necessary to lipid extract oyster tissues in all cases, and that C:N thresholds for lipid extraction in other species may not be reliable for organisms such as oysters that store glycogen. Our data indicate that minimizing unnecessary lipid extraction through preliminary testing will save researchers time and expense by avoiding superfluous sample handling, reducing concern over secondary effects on data quality, and reducing the costs of reagents and additional separate stable isotope analysis to ensure analytical accuracy.

PMID- 27709714 TI - Using longitudinal mixed methods to study the development of professional behaviours during pharmacy work-based training. AB - Recent longitudinal investigations of professional socialisation and development of professional behaviours during work-based training are lacking. Using longitudinal mixed methods, this study aimed to explore the development of professional behaviours during a year of intensive work-based (pre-registration) training in pharmacy. Twenty trainee pharmacists and their tutors completed semi structured interview and professional behaviour questionnaires at four time points during 2011/2012: months 1, 4 and 9 during training and 4 months after registration; tutors participated in months 1 and 9. Interviews were analysed thematically using template analysis, and questionnaires were analysed using ANOVA and t-tests. Self-assessed (trainee) and tutor ratings of all elements of professional behaviours measured in questionnaires (appearance, interpersonal/social skills, responsibility, communication skills) increased significantly from the start of pre-registration training to post-registration. Some elements, for example, communication skills, showed more change over time compared with others, such as appearance, and continued to improve post registration. Qualitative findings highlighted the changing roles of trainees and learning experiences that appeared to facilitate the development of professional behaviours. Trainees' colleagues, and particularly tutors, played an essential part in trainees' development through offering support and role modelling. Trainees noted that they would have benefited from more responsibilities during training to ease the transition into practising as a responsible pharmacist. Longitudinal mixed methods can unpack the way in which professional behaviours develop during work-based training and allow researchers to examine changes in the demonstration of professional behaviours and how they occur. Identifying areas less prone to change allows for more focus to be given to supporting trainees in areas where there is a development need, such as communication skills and holding increasing responsibility. PMID- 27709715 TI - Carbon Nanotube/Boron Nitride Nanocomposite as a Significant Bifunctional Electrocatalyst for Oxygen Reduction and Oxygen Evolution Reactions. AB - It is an immense challenge to develop bifunctional electrocatalysts for oxygen reduction reactions (ORR) and oxygen evolution reactions (OER) in low temperature fuel cells and rechargeable metal-air batteries. Herein, a simple and cost effective approach is developed to prepare novel materials based on carbon nanotubes (CNTs) and a hexagonal boron nitride (h-BN) nanocomposite (CNT/BN) through a one-step hydrothermal method. The structural analysis and morphology study confirms the formation of a homogeneous composite and merging of few exfoliated graphene layers of CNTs on the graphitic planes of h-BN, respectively. Moreover, the electrochemical study implies that CNT/BN nanocomposite shows a significantly higher ORR activity with a single step 4-electron transfer pathway and an improved onset potential of +0.86 V versus RHE and a current density of 5.78 mA cm-2 in alkaline conditions. Interestingly, it exhibits appreciably better catalytic activity towards OER at low overpotential (eta=0.38 V) under similar conditions. Moreover, this bifunctional catalyst shows substantially higher stability than a commercial Pt/C catalyst even after 5000 cycles. Additionally, this composite catalyst does not show any methanol oxidation reactions that nullify the issues due to fuel cross-over effects in direct methanol fuel cell applications. PMID- 27709716 TI - Room-Temperature Synthesis of Covalent Organic Frameworks with a Boronic Ester Linkage at the Liquid/Solid Interface. AB - With various prospected applications in the field of nanoelectronics and catalysis, on-surface synthesis of single-layer covalent organic frameworks (surface COFs) with designable structures and properties have attracted enormous interest. Herein, we report on a scanning tunneling microscopic investigation of the surface-confined synthesis of a covalently bonded boronic ester network directly at the octanoic acid/ highly oriented pyrolytic graphite(HOPG) interface under room temperature. The dynamic reaction process was investigated in detail. STM results indicate that the surface networks undergo structural evolution from a hybrid covalent/noncovalent multiwall porous network to single-wall hexagonal COF with the decrease of monomer concentration. Further experimental observation disclosed that the boronic ester-linked system is sensitive to instantaneous voltage pulses and the stimulation of the STM tip. In addition, the 1 H NMR spectra has further confirmed that the surface and octanoic acid may play important roles in promoting the reaction between 4,4'-phenylazobenzoyl diboronic acid (ABBA) and 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP) building units. PMID- 27709717 TI - Changing the balance of social care for older people: simulating scenarios under demographic ageing in New Zealand. AB - The demographic ageing of New Zealand society, as elsewhere in the developed world, has dramatically increased the proportion of older people (aged 65 years and over) in the population. This has major policy implications for the future organisation of social care. Our objective was to test the effects on social care use, first, of putative changes in the overall disability profile of older people, and second, of alterations to the balance of their care, i.e. whether it was community-based or residential. In order to undertake these experiments, we developed a microsimulation model of the later life course using individual-level data from two official national survey series on health and disability, respectively, to generate a synthetic version which replicated original data and parameter settings. A baseline projection under current settings from 2001 to 2021 showed moderate increases in disability and associated social care use. Artificially decreasing disability levels, below the baseline projection, only moderately reduced the use of community care (both informal and formal). Scenarios implemented by rebalancing towards informal care use moderately reduced formal care use. However, only moderate compensatory increases in community-based care were required to markedly decrease the transition to residential care. The disability impact of demographic ageing may not have a major negative effect on system resources in developed countries like New Zealand. As well as healthy ageing, changing the balance of social care may alleviate the impact of increasing demand due to an expanding population of older people. PMID- 27709718 TI - Body composition assessed by dual-energy X-ray absorptiometry predicts early infectious complications after liver transplantation. AB - BACKGROUND: It is challenging to identify malnutrition, which is a risk factor for poor outcome in patients with liver cirrhosis. In the present study, we aimed to investigate the prevalence of malnutrition among patients listed for liver transplantation, as assessed by different methods, and also to relate dual-energy X-ray absorptiometry (DXA) to short-term post-transplant outcomes. METHODS: In this retrospective cohort study, we reviewed the medical records of 106 patients who underwent liver transplantation in 2009-2012. Body composition was assessed by the fat-free mass index (FFMI) and fat mass index (FMI) obtained using DXA. Severe infections within 1 month, length of stay in intensive care unit and length of hospital stay were endpoints of primary interest. RESULTS: The prevalence of malnutrition was 2-20% depending on sex and the assessment method. Thirty-nine (37%) patients developed severe infections within 1 month after liver transplantation. In multivariate analysis with logistic regression, body composition was significantly associated with post-operative infection when measured with FFMI (P = 0.043) but not with FMI (P = 0.087). Post-operative dialysis (P = 0.004) and post-operative infections (P < 0.001) were significantly associated with length of stay in hospital. Post-operative bleeding (P = 0.015), duration of mechanical ventilation (P < 0.001) and the need for dialysis (P < 0.001), but not body composition, were significant predictors of the length of stay in the intensive care unit. CONCLUSIONS: The prevalence of malnutrition depends on assessment method. FFMI is an independent predictor for early post transplant infections. Body composition measured by DXA during the pretransplant evaluation provides valuable information about nutritional status in patients with liver cirrhosis. PMID- 27709719 TI - Natural Abundance 15 N and 13 C Solid-State NMR Chemical Shifts: High Sensitivity Probes of the Halogen Bond Geometry. AB - Solid-state nuclear magnetic resonance (SSNMR) spectroscopy is a versatile characterization technique that can provide a plethora of information complementary to single crystal X-ray diffraction (SCXRD) analysis. Herein, we present an experimental and computational investigation of the relationship between the geometry of a halogen bond (XB) and the SSNMR chemical shifts of the non-quadrupolar nuclei either directly involved in the interaction (15 N) or covalently bonded to the halogen atom (13 C). We have prepared two series of X bonded co-crystals based upon two different dipyridyl modules, and several halobenzenes and diiodoalkanes, as XB-donors. SCXRD structures of three novel co crystals between 1,2-bis(4-pyridyl)ethane, and 1,4-diiodobenzene, 1,6 diiodododecafluorohexane, and 1,8-diiodohexadecafluorooctane were obtained. For the first time, the change in the 15 N SSNMR chemical shifts upon XB formation is shown to experimentally correlate with the normalized distance parameter of the XB. The same overall trend is confirmed by density functional theory (DFT) calculations of the chemical shifts. 13 C NQS experiments show a positive, linear correlation between the chemical shifts and the C-I elongation, which is an indirect probe of the strength of the XB. These correlations can be of general utility to estimate the strength of the XB occurring in diverse adducts by using affordable SSNMR analysis. PMID- 27709720 TI - Differential micro ribonucleic acid expression profiling in ovarian endometrioma with leuprolide acetate treatment. AB - AIM: Micro ribonucleic acids (miRNAs) play an important pathological role in endometriosis. Leuprolide acetate, an analog of gonadotropin-releasing hormone, is widely used to treat endometriosis; however, the molecular mechanisms involved in endometriotic tissue regression remain unclear. We performed miRNA expression profiling of clinical ovarian endometrioma to obtain insight into the effects of leuprolide acetate treatment. METHODS: We obtained clinical samples from nine normal eutopic endometrium, eight ovarian endometriotic, and 12 leuprolide acetate-treated endometriotic tissues. We compared the miRNA expression profiles of the three groups by performing TaqMan Array MicroRNA Card and bioinformatic analysis. RESULTS: Two miRNAs, miR-939 and miR-154, were upregulated in endometriotic tissue and downregulated in leuprolide acetate-treated endometriotic tissue. Five miRNAs (miR-146a, miR-142-3p, miR-136*, miR-125b-1* and miR-15b*) were unchanged in endometriotic tissue but were upregulated under leuprolide acetate treatment. Ingenuity pathway analysis using predicted target genes for the seven identified miRNAs suggested the involvement of a range of pathways, including axonal guidance, bone morphogenetic protein, phosphatase and tensin homolog and nitric oxide signaling; molecular mechanisms of cancer; and the adipogenesis and signal transducer and activator of transcription 3 (STAT3) pathways. CONCLUSIONS: To our knowledge, this is the first report profiling the miRNAs of endometrioma under leuprolide acetate treatment. The expression of seven miRNAs was modulated, concomitant with the disease state. This result gives new insight into the effects of leuprolide acetate treatment. Further investigation using quantitative reverse transcriptase-polymerase chain reaction and immunohistochemistry will allow us to validate the results of this study and to explore new therapeutic targets and biomarkers of endometriosis. PMID- 27709721 TI - Periphery-Functionalized Porous Organic Cages. AB - By synthesizing derivatives of a trans-1,2-diaminocyclohexane precursor, three new functionalized porous organic cages were prepared with different chemical functionalities on the cage periphery. The introduction of twelve methyl groups (CC16) resulted in frustration of the cage packing mode, which more than doubled the surface area compared to the parent cage, CC3. The analogous installation of twelve hydroxyl groups provided an imine cage (CC17) that combines permanent porosity with the potential for post-synthetic modification of the cage exterior. Finally, the incorporation of bulky dihydroethanoanthracene groups was found to direct self-assembly towards the formation of a larger [8+12] cage, rather than the expected [4+6], cage molecule (CC18). However, CC18 was found to be non porous, most likely due to cage collapse upon desolvation. PMID- 27709722 TI - Cardiogenic shock in intensive care units: evolution of prevalence, patient profile, management and outcomes, 1997-2012. AB - AIM: To address the paucity of data on the characteristics, outcome and temporal trends in mortality of cardiogenic shock (CS) patients admitted to intensive care units (ICUs) we examined key features, variations in mortality from CS, and predictors of death in ICU patients over the past 15 years. METHODS AND RESULTS: From the 1997-2012 database of the College des Utilisateurs de Bases de donnees en Reanimation (CUB-Rea) that prospectively collects data from ICUs in the greater Paris area, we determined temporal trends in the incidence of CS, patient outcomes [Crude and Simplified Acute Physiology Score (SAPS)-II Standardized Mortality] and predictors of in-ICU mortality. Of the 316 905 ICU admissions, 19 416 (6.1%) exhibited CS, with incidence increasing from 4.1% to 7.7% (P < 0.001). Over time, the age of admitted patients decreased by 2.7 years [95% confidence interval (CI), -2.0 to -3.4] and SAPS-II increased by 5.8% (95% CI 4.8-6.8) from 58.7 +/- 25.3 to 64.5 +/- 23.3 (P < 0.001). Crude in-ICU mortality declined from 50% to 45% (-5.6%; 95% CI -7.7 to -3.5) as SAPS-II Standardized ICU mortality rates decreased from 56.5% to 44.2% (P < 0.001). A more recent time-period was an independent correlate of decreased mortality in multivariate analyses. The decrease in mortality rate was more marked in patients with decompensated heart failure, cardiac arrest, or acute myocardial infarction. CONCLUSIONS: Patients with CS represent a greater proportion of patients admitted to ICUs over the past 15 years, having become younger but more critically ill. Although their mortality has decreased, suggesting improved overall patient management, it remains particularly high, warranting further research specifically focused on this population.

AB - AIM: To identify the prevalence, management and complications associated with central venous access devices (CVADs) within Australian paediatric facilities, providing a map for clinicians, researchers and managers to focus solutions. METHODS: A point prevalence audit and survey of CVAD practices in Australian tertiary paediatric hospitals between September and November 2015, using validated data collection tools. RESULTS: Across the six sites, 1027 patients were screened with CVADs prevalent in 26.1% (n = 268), and 261 CVADs in 248 patients available for audit. Variations in management were evident with dressings not meeting the basic criteria of clean, dry and intact for 13.5% of CVADs (n = 35), and non-sterile dressings used to reinforce 26.4% of CVADs (n = 69). Almost half of CVADs (49.4%; n = 132) had no documentation regarding site assessment in the previous 4 h, and 13.4% had no planned use in the next 24 h (35 CVAD). CVAD-associated complications within the previous 7 days were evident in 9.5% of CVADs (n = 27), most commonly catheter blockage (5.7% CVAD, n = 15), and bloodstream infection (1.9% CVAD, n = 5). Peripherally inserted central catheters (16.9%) in comparison to other catheter types (7.4%; P = 0.04), and subsequent CVADs (14.1%) in comparison to initial CVADs (6.5%; P = 0.04), had significantly higher proportions of CVAD-associated complications in the previous 7 days. Variation between the sites' guidelines was evident across many practices. CONCLUSIONS: CVADs are prevalent and essential for paediatric health care; however, complications remain a significant problem. Areas identified for improvement were local CVAD guidelines, regular documentation of CVAD site assessment and review of dressing products to improve integrity.

AB - RATIONAL, AIMS AND OBJECTIVES: The aim of this review was to identify general theoretical frameworks used in online social network interventions for behavioral change. To address this research question, a PRISMA-compliant systematic review was conducted. METHODS: A systematic review (PROSPERO registration number CRD42014007555) was conducted using 3 electronic databases (PsycINFO, Pubmed, and Embase). Four reviewers screened 1788 abstracts. RESULTS: 15 studies were selected according to the eligibility criteria. Randomized controlled trials and controlled studies were assessed using Cochrane Collaboration's "risk-of-bias" tool, and narrative synthesis. Five eligible articles used the social cognitive theory as a framework to develop interventions targeting behavioral change. Other theoretical frameworks were related to the dynamics of social networks, intention models, and community engagement theories. Only one of the studies selected in the review mentioned a well-known theory from the field of health psychology. CONCLUSION: Conclusions were that guidelines are lacking in the design of online social network interventions for behavioral change. Existing theories and models from health psychology that are traditionally used for in situ behavioral change should be considered when designing online social network interventions in a health care setting.

AB - For older adults with osteoporosis, a fall resulting in hip fracture is a life changing event from which only one-third fully recover. Current best evidence argues strongly for elderly patients to bear weight on their repaired hip fracture immediately after their surgery to maximize their chances of full or nearly full recovery. Patient stakeholders in Canada have argued that some surgeons fail to issue "weight-bearing-as-tolerated" (WBAT) orders in all eligible cases, protecting their bony repair but contributing to increased mortality and long-term disability rates. In collaboration with a national stakeholder organization, Bone and Joint Canada, we interviewed 20 orthopedic surgeons across Canada who perform hip fracture repair surgery, with the aim of understanding their attitudes and behavior toward patient management regarding weight bearing. Qualitative content analysis, in which themes are identified and agreed by multiple coders, suggested that both patient characteristics and surgeon factors influence surgeons' postoperative weight-bearing orders. While almost all respondents agreed that weight bearing as tolerated is indeed therapeutic for most hip fracture repair or replacement patients, surgeons also described certain patient characteristics that would diminish the value of immediate weight bearing, including poor bone quality and certain types of fracture pattern. Surgeon factors that affect postoperative mobilization orders include choice of construct, previous experience of construct failure, and lack of local audit data regarding past weight-bearing decisions and patient outcomes. Thus, although familiar with best practice guidelines, surgeons also have "rules to break the rules." In an era when "good" medicine leans toward science rather than art, the role of individual experience in decision making with regard to hip fracture care continues to be important and would benefit from being discussed openly.

AB - AIMS: To define anti-Campylobacter jejuni activity of an extract from waste skins and seeds of Pinot noir grapes (GSS), resveratrol and possible resistance mechanisms, and the influence of these on Camp. jejuni morphology. METHODS AND RESULTS: Using gene-specific knock-out Camp. jejuni mutants and an efflux pump inhibitor, we showed CmeABC as the most active efflux pump for extrusion across the outer membrane of GSS extract and resveratrol. Using polystyrene surface and pig small intestine epithelial (PSI) and human foetal small intestine (H4) cell lines, GSS extract shows an efficient inhibition of adhesion of Camp. jejuni to these abiotic and biotic surfaces. CONCLUSIONS: Low doses of GSS extract can inhibit Camp. jejuni adhesion to polystyrene surfaces and to PSI and H4 cells, and can thus modulate Camp. jejuni invasion and intracellular survival. SIGNIFICANCE AND IMPACT OF THE STUDY: An understanding of the activities of GSS extract and resveratrol as bacterial growth inhibitors and the specific mechanisms of cell accumulation is crucial for our understanding of Camp. jejuni resistance. GSS extract inhibition of Camp. jejuni adhesion to abiotic and biotic surfaces provides a further step towards the application of new innovative strategies to control Campylobacter contamination and infection via the food chain. PMID- 27709727 TI - Leaf spot disease adversely affects human health-promoting constituents and withanolide biosynthesis in Withania somnifera (L.) Dunal. AB - AIMS: The present work investigates the implication of leaf spot disease on the antioxidant potential and commercial value of pharmaceutically important constituents of Withania somnifera, a high-valued medicinal plant. METHODS AND RESULTS: Leaf spot disease was induced in W. somnifera by inoculating Alternaria alternata (Fr.) Keiss. pathogen. Total polyphenolic content and antioxidant potential showed a significant decrease during leaf spot disease. Evaluation of pharmaceutically active constituents withaferin A, withanone and withanolide A utilizing high-performance liquid chromatography showed a significant decrease in diseased samples as compared to healthy ones. Quantitative expression of major genes involved in withanolide biosynthesis also showed down-regulation in diseased samples. Alterations in the ultra-structure of chloroplasts were also analysed under transmission electron microscopy to get a better insight into the changes of withanolide biosynthesis in leaf during disease infestation. CONCLUSIONS: The present work suggests that when the pathogenic fungus invades the host plants, it evokes multiple responses, which could be studied at various levels. The knowledge gained from this work will provide appropriate rationale for controlling the bio-deterioration of the pharmaceutically active metabolites in W. somnifera and development of suitable strategies against leaf spot disease. SIGNIFICANCE AND IMPACT OF THE STUDY: This is the first study to investigate the effect of leaf spot disease on the human health-promoting constituents and withanolide biosynthesis in this high-valued medicinal plant. PMID- 27709728 TI - C-terminal domains of bacterial proteases: structure, function and the biotechnological applications. AB - C-terminal domains widely exist in the C-terminal region of multidomain proteases. As a beta-sandwich domain in multidomain protease, the C-terminal domain plays an important role in proteolysis including regulation of the secretory process, anchoring and swelling the substrate molecule, presenting as an inhibitor for the preprotease and adapting the protein structural flexibility and stability. In this review, the diversity, structural characteristics and biological function of C-terminal protease domains are described. Furthermore, the application prospects of C-terminal domains, including polycystic kidney disease, prepeptidase C-terminal and collagen-binding domain, in the area of medicine and biological artificial materials are also discussed. PMID- 27709729 TI - Study on differentiation during embryonic development across selective and ancestral breeds. AB - In order to explore the effect of strain on diverging post-hatch muscle properties, muscle regulation during embryo development was investigated in selected and unselected breeds. Four broiler strains were used: JingNing (JN) chicken (a Chinese native chicken), HuangYu (HY) broiler, BaiYu (BY) broiler and Hyline layer (commercial crossbred chickens). Results showed that the four breeds had almost the same characteristic during different incubation periods. BY broilers moved more than JN and Hyline layers from Hamburger & Hamilton stage (HH)24 to HH31 (P < 0.05). HY broilers moved more than JN and Hyline layers from HH27 to HH31 (P < 0.01). All the embryos were heavier daily from HH24 to ED18 (P < 0.05); broilers presented greater body weights than JN and hyline layers (P > 0.05); broilers presented smaller fiber diameter than JN chickens before HH31 (P > 0.05). From then on, JN chicken exhibited smaller fiber diameter compared to the broilers (P > 0.05). Western blotting indicated all the breeds had continuous insulin-like growth factor-I (IGF-I) expression, with the highest expression level in broilers from HH19 to HH24 and highest expression level in JN chicks from HH27 to HH31. The results indicated that the diverging growth among breeds was already shown in embryonic stages; the different expression patterns of IGF-I may be involved in cell proliferation and differentiation.

AB - The morphology and ultrastructure of the rectum in Poecilimon cervus Karabag, 1950 (Orthoptera, Tettigoniidae) were analyzed by light microscope, scanning (SEM) and transmission electron microscopes (TEM). The rectum is the final part of the digestive tract that plays an important role in water reabsorption in insects and so provides osmoregulation. In the transverse sections, six rectal pads and columnar epithelium can be distinguished. The cuticular intima lines the lumen at the apical side of the epithelium. In the cytoplasm, there are numerous mitochondria, some endocytic vesicles, secreting vesicles whose sizes differ according to the area in the cell, and a nucleus with globular in shape. With this study, we aimed to demonstrate the ultrastructure of the rectum of P. cervus and differences or similarities of with other species.

AB - Octulene, the higher homologue of kekulene and septulene, was synthesized using the fold-in method. This new hydrocarbon macrocycle contains a large 24-membered inner circuit, which is peripherally fused to 24 benzene rings. Such an arrangement produces considerable hyperbolic distortion of the pi-conjugated surface. The consequences of distortion in octulene were explored using photophysical methods, which revealed a reduced electronic band gap and greater flexibility of the pi system. Octulene contains a functional cavity with a diameter larger than 5.5 A that is capable of efficiently binding the chloride anion in a nonpolar solvent (Ka = 2.2(4)*104 m-1 , 1 % dichloromethane (DCM) in benzene). The octulene-chloride interaction is stabilized by eight weak C(sp2 )H???Cl bonds, providing the first example of a hydrocarbon-based anion receptor. PMID- 27709734 TI - What factors influence successful recruitment of siblings of individuals with first episode psychosis to e-health interventions? A qualitative study. AB - BACKGROUND: Recruitment to clinical research studies can prove complex. This is particularly true of mental health research, given factors such as confidentiality, capacity and consent, or when attempting to recruit family members as opposed to service users themselves. AIM: This study investigated the challenges experienced and strategies employed in the recruitment of siblings of people with first episode psychosis using Early Intervention in Psychosis Services (EIPS) in England. METHODS: As part of a randomized controlled trial (RCT) of an e-health intervention for siblings, we conducted a process evaluation study whereby semistructured interview was undertaken with clinical and research staff involved in recruitment of siblings. Data were analysed thematically. RESULTS: Twelve participants from six EIPS were interviewed. Data analysis revealed seven key themes: (i) limited comprehensive family data available; (ii) data governance and consent issues; (iii) organizational factors; (iv) convoluted recruitment methods; (v) concerns about service users' opinions; (vi) fluidity in siblings' needs and expectations; and (vii) strategies to enhance recruitment. CONCLUSIONS: Recruitment challenges identified in this study concerned administrative, organizational, process and attitudinal issues. These are similar to other studies recruiting mental health service users as well as family members. Failure to recruit to target implies that studies are underpowered to detect potential statistically or clinically meaningful changes. Future studies should establish how best to enhance family inclusiveness in clinical practice and research. PMID- 27709733 TI - EGF-Amphiregulin Interplay in Airway Stem/Progenitor Cells Links the Pathogenesis of Smoking-Induced Lesions in the Human Airway Epithelium. AB - The airway epithelium of cigarette smokers undergoes dramatic remodeling with hyperplasia of basal cells (BC) and mucus-producing cells, squamous metaplasia, altered ciliated cell differentiation and decreased junctional barrier integrity, relevant to chronic obstructive pulmonary disease and lung cancer. In this study, we show that epidermal growth factor receptor (EGFR) ligand amphiregulin (AREG) is induced by smoking in human airway epithelium as a result of epidermal growth factor (EGF)-driven squamous differentiation of airway BC stem/progenitor cells. In turn, AREG induced a unique EGFR activation pattern in human airway BC, distinct from that evoked by EGF, leading to BC- and mucous hyperplasia, altered ciliated cell differentiation and impaired barrier integrity. Further, AREG promoted its own expression and suppressed expression of EGF, establishing an autonomous self-amplifying signaling loop in airway BC relevant for promotion of EGF-independent hyperplastic phenotypes. Thus, EGF-AREG interplay in airway BC stem/progenitor cells is one of the mechanisms that mediates the interconnected pathogenesis of all major smoking-induced lesions in the human airway epithelium.

AB - OBJECTIVES: The objective of the study is to develop a novel tool-the Burnout Battery-for briefly screening burnout among oncology professionals in China and assessing its validity. METHODS: A multicenter study was conducted in doctors and nurses of the oncology departments in China from November 2014 to May 2015. The Burnout Battery was administered with the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) and the Doctors' Job Burnout Questionnaire. RESULTS: Of 538 oncology doctors and nurses who completed all the survey, using MBI-HSS as the standard tool for measuring burnout, 52% had emotional exhaustion, 39.4% had depersonalization, and 59.3% had a low sense of personal accomplishment. Receiver operating characteristic curve analyses showed that the best cut-off of the Burnout Battery was the battery with 3 bars, which yielded best sensitivity and specificity against all the 3 subscales of MBI-HSS. With this cut-off, nearly half of Chinese oncology professionals (46.8%) had burnout. The Burnout Battery correlated significantly with subscales of the MBI-HSS and the Doctors' Job Burnout Questionnaire. In multiple logistic regression analysis, those who worked more than 60 hours per week and who thought clinical work was the most stressful part of their job were more likely to experience burnout. CONCLUSION: Chinese oncology professionals exhibit high levels of burnout. The Burnout Battery appears to be a simple and useful tool for screening burnout. Working long hours and perceiving clinical work as the most stressful part of the job were the main factors associated with burnout. PMID- 27709736 TI - Generation of Functional Human Retinal Ganglion Cells with Target Specificity from Pluripotent Stem Cells by Chemically Defined Recapitulation of Developmental Mechanism. AB - Glaucoma is a complex group of diseases wherein a selective degeneration of retinal ganglion cells (RGCs) lead to irreversible loss of vision. A comprehensive approach to glaucomatous RGC degeneration may include stem cells to functionally replace dead neurons through transplantation and understand RGCs vulnerability using a disease in a dish stem cell model. Both approaches require the directed generation of stable, functional, and target-specific RGCs from renewable sources of cells, that is, the embryonic stem cells and induced pluripotent stem cells. Here, we demonstrate a rapid and safe, stage-specific, chemically defined protocol that selectively generates RGCs across species, including human, by recapitulating the developmental mechanism. The de novo generated RGCs from pluripotent cells are similar to native RGCs at the molecular, biochemical, functional levels. They also express axon guidance molecules, and discriminate between specific and nonspecific targets, and are nontumorigenic. Stem Cells 2017;35:572-585. PMID- 27709739 TI - Perineural invasion on biopsy is associated with upstaging at radical prostatectomy in Gleason score 3 + 4 = 7 prostate cancer. AB - This study assesses if perineural invasion (PNI) detected on biopsy with Gleason score (GS) 3 + 4 = 7 prostate cancer (PCa) is associated with upstaging/upgrading of disease after radical prostatectomy (RP). 154 patients with GS 3 + 4 = 7 PCa diagnosed from biopsy who underwent RP were assessed for PNI. The percentage of biopsy sites with PNI (%PNI) was also calculated. Pattern 4 morphologies (ill defined glands [IDG], fused, cribriform, and glomerulations) were also assessed. Clinical information, GS and stage after RP were retrieved from the medical records. 45 % (69/154) of patients were upstaged (>=pT3) and 29 % (44/154) were upgraded to GS >3 + 4 = 7 after RP. 37 % (57/154) of patients had PNI which was associated with upstaging (RR 1.4; P = 0.04) but not upgrading (RR 0.9; P = 0.7). There was higher %PNI in upstaged patients (12.1 % +/- 1.8 vs. 7.1 % +/- 1.5, P = 0.03) with a significant correlation between %PNI and >=pT3 (r = 0.178, P = 0.027). After multivariate analysis, only cribriform formations were significantly associated with upstaging (P = 0.009). The presence of PNI in biopsies with GS 3 + 4 = 7 PCa is associated with upstaging at RP but is a weaker predictor of >=pT3 disease than cribriform morphology. PMID- 27709738 TI - Wnt-beta-catenin signaling regulates ABCC3 (MRP3) transporter expression in colorectal cancer. AB - We determined the gene expression profiles for 48 ATP binding cassette (ABC) transporters in matched colon cancer and normal colon tissues in order to provide insight into the mechanisms underlying expression of transporters related to colon carcinogenesis. The expression of ABCB1, ABCC1, ABCC2, ABCC3, and ABCG2 was altered in association with colon carcinogenesis. Among these transporters, the expression of ABCC3 was repressed by Wnt signaling pathway in colon cancer cell lines. Knockdown of the pathway components transcription factor 7-like 2 (TCF7L2) or beta-catenin thus increased ABCC3 expression, whereas activation of Wnt signaling with inhibitors of glycogen synthase kinase-3beta (GSK-3beta) reduced it. ChIP and luciferase reporter assays also showed that TCF7L2 binds to the ABCC3 locus and regulates its expression. Finally, overexpression of ABCC3 in colon cancer cells conferred resistance to anticancer drug-induced cytotoxicity. Our data thus suggest that Wnt signaling represses ABCC3 expression during colon carcinogenesis, and that subsequent upregulation of ABCC3 expression during drug treatment might contribute to acquired drug resistance. PMID- 27709740 TI - Effects of organic loading rate on hydrogen and volatile fatty acid production and microbial community during acidogenic hydrogenesis in a continuous stirred tank reactor using molasses wastewater. AB - AIMS: Microbial community associated with hydrogen production and volatile fatty acids (VFAs) accumulation was characterized in acidogenic hydrogenesis using molasses wastewater as a feedstock. METHODS AND RESULTS: Hydrogen and VFAs production were measured under an organic loading rate (OLR) from 19 to 35 g-COD l-1 day-1 . The active microbial community was analysed using RNA-based massively parallel sequencing technique, and their correlation patterns were analysed using networking analysis. The continuous stirred tank reactor achieved stable hydrogen production at different OLR conditions, and the maximum hydrogen production rate (HPR) was 1.02 L-H2 l-1 day-1 at 31.0 g-COD l-1 day-1 . Butyrate (50%) and acetate (38%) positively increased with increase in OLR. Total VFA production stayed around 7135 mg l-1 during the operation period. Although Clostridiales and Lactobacillales were relatively abundant, the HPR was positively associated with Pseudomonadaceae and Micrococcineae. Total VFA and acetate, butyrate and propionate concentrations were positively correlated with lactic acid bacteria (LAB) such as Bacillales, Sporolactobacillus and Lactobacillus. CONCLUSIONS: The close relationship between Pseudomonadaceae and Micrococcineae, and LAB play important roles for stable hydrogen and VFA production from molasses wastewater. SIGNIFICANCE AND IMPACT OF THE STUDY: Microbial information on hydrogen and VFA production can be useful to design and operate for acidogenic hydrogenesis using high strength molasses wastewater.

PMID- 27709742 TI - Effects of child abuse, adolescent violence, peer approval and pro-violence attitudes on intimate partner violence in adulthood. AB - BACKGROUND: Children's exposure to violence increases their risk for later victimisation and perpetration of intimate partner violence (IPV). However, the relative influence of child abuse, adolescent violence, peer approval of violence and pro-violence attitudes on later IPV is not well established. AIMS: Analyses focus on the prediction of adult IPV from variables measured in childhood and adolescence to establish the unique influence of earlier victimisation and perpetration of violence, as well as other variables grounded in theory and empirical findings. METHODS: Data are from a longitudinal study that began in the 1970s with a sample of 457 preschool-aged children who were reassessed as adults. Outcomes of adult IPV victimisation and perpetration types were regressed on predictors of parent-reported child abuse, officially recorded child maltreatment, adolescent victimisation, violence perpetration, pro-violence attitudes and peer approval of violence during adolescence, controlling for childhood Socio Economic Status (SES), age in adolescence and gender. RESULTS: Dating violence victimisation and peer approval of dating violence in adolescence emerged as the unique predictors of IPV victimisation and perpetration in adulthood. Official child maltreatment predicted IPV perpetration. CONCLUSIONS: Results underscore the importance of prevention programmes and strategies to disrupt the cycle of violence at its early stages, as well as interventions during adolescence targeting peer influences.

AB - AIM: The objective of this paper is to review risk instruments that have been used in the assessment of the potential for violence within the dating relationships of young people. METHOD: A review of the dating violence literature was conducted to identify risk assessment approaches that have been used to predict harmful behaviour within the dating relationships of people aged between 15 and 30 years. Risk assessments were evaluated on recommended quality criteria: predictive validity, accuracy (sensitivity and specificity) and inter-rater reliability. RESULTS: Only five studies describing assessments that focused specifically on dating violence risk factors were selected for review. Three assessments encompassed dating behaviours by victims that have been associated with an increased risk of further victimisation. CONCLUSIONS: Drawing on this evidence, we conclude that young people appear to be at greater risk of encountering dating violence if they have experienced violence in earlier attachment relationships; if their skills for coping with conflict and responding to coercion are limited and if the presence of peer influences reinforces offence supportive attitudes. The reliability and validity of existing intimate partner violence risk assessments that conceptually overlap with elements of dating violence risk warrant investigation to inform risk assessment developments in this field and, building on this, possible interventions to minimise future harm.

PMID- 27709744 TI - Risk factors for dating violence versus cohabiting violence: Results from the third generation of the Cambridge Study in Delinquent Development. AB - BACKGROUND: Dating violence is an important problem. Evidence suggests that women are more likely to perpetrate dating violence. AIMS: The present study investigates the prevalence of dating violence compared with cohabiting violence in a community sample of men and women and assesses to what extent child and adolescent explanatory factors predict this behaviour. A secondary aim is to construct a risk score for dating violence based on the strongest risk factors. METHODS: The Cambridge Study in Delinquent Development is a prospective longitudinal survey of 411 men (generation 2) born in the 1950s in an inner London area. Most recently, their sons and daughters [generation 3 (G3)] have been interviewed regarding their perpetration of dating and cohabiting violence, utilising the Conflict Tactics Scale. Risk factors were measured in four domains (family, parental, socio-economic and individual). RESULTS: A larger proportion of women than men perpetrated at least one act of violence towards their dating partner (36.4 vs 21.7%). There was a similar pattern for cohabiting violence (39.6 vs 21.4%). A number of risk factors were significantly associated with the perpetration of dating violence. For G3 women, these included a convicted father, parental conflict, large family size and poor housing. For G3 men, these included having a young father or mother, separation from the father before age 16, early school leaving, frequent truancy and having a criminal conviction. A risk score for both men and women, based on 10 risk factors, significantly predicted dating violence. CONCLUSION: Risk factors from four domains were important in predicting dating violence, but they were different for G3 men and women. It may be important to consider different risk factors and different risk assessments for male compared with female perpetration of dating violence. Early identification and interventions are recommended. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27709745 TI - From early dating violence to adult intimate partner violence: Continuity and sources of resilience in adulthood. AB - BACKGROUND: Previous literature has found continuity for intimate partner violence, but little research has explored continuity between dating violence and adult intimate partner violence (IPV) or whether protective factors may attenuate this relationship. AIMS: This research hypothesised a positive relationship between dating violence in early adulthood and later adulthood IPV and that support and attachment would provide buffering and direct protection for this relationship. METHODS: Data from the Rochester Youth Development Study were used to explore these questions through negative binomial regression. RESULTS: Dating violence was statistically significantly related to an increase of adult IPV. Family support, parental reports of attachment to the subject, peer support and parenting-related social support all were protective factors that provided a direct effect for those respondents perpetrating dating violence. None of the protective factors provided buffering protection between dating violence and adult IPV. CONCLUSIONS: Results confirm significant continuity between dating violence and IPV and that support from peers and family, parenting-related support and parental reports of attachment protect an individual from continuing to engage in intimate partner violence throughout adulthood. Bolstering these supportive relationships may help provide points of intervention to interrupt the link between early dating violence and later adulthood IPV.

AB - BACKGROUND: Teen dating violence (TDV) is a common phenomenon of great public concern. TDV may lead to severe long-term consequences for victims and offenders, and even more so for females than for males. AIM: The aim of this paper is to investigate possible underlying factors for involvement in TDV either as a perpetrator or a victim. Social learning theory is commonly used to explain internalisation of parents' behaviour on children's behavioural expressions, but less so on parents' emotion regulation as a direct link to later TDV. METHOD: We used longitudinal data from the Pittsburgh Girls Study (N = 2450) to investigate if and how parents' positive and negative emotion regulation is related to TDV, controlling for early aggression and race. RESULTS: Results show a moderately strong association between parents' negative emotion regulation and their daughters' involvement in serious dating violence. We also found that many more African American girls were involved in TDV compared to Caucasian girls, both as a perpetrator and victim. CONCLUSIONS AND PRACTICAL IMPLICATIONS: We discuss directions for future research focusing on emotion regulation and dating violence. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27709746 TI - Dating violence and physical health: A longitudinal lens on the significance of relationship dynamics and anti-social lifestyle characteristics. AB - BACKGROUND: Scholars have documented the significant physical health consequences of intimate partner violence. Yet, because existing research draws primarily on clinical samples of adult women, it is unclear whether exposure to dating violence is related to health detriments among young men and women. Furthermore, data limitations largely have precluded consideration of the mechanisms underlying these previously observed associations. AIMS: We sought to examine the direct association between dating violence and self-rated physical health during adolescence and across the transition to adulthood. We also directed attention to potential mediating and confounding factors, including negative relationship dynamics, anti-social lifestyle characteristics and physical health correlates. METHODS: Drawing on five waves of data from the Toledo Adolescent Relationships Study (n = 3746 person-periods), we used growth curve analyses to examine these associations among a sample of young men and women in dating relationships. RESULTS: Longitudinal analyses revealed that dating violence was associated with declines in self-rated physical health across the period from adolescence to young adulthood. This effect, however, was attenuated with the inclusion of negative relationship dynamics. CONCLUSIONS: Findings suggest the need to further examine the physical health consequences of dating violence, with a particular focus on the relationship context and other potential confounding forces.

AB - AIM: We estimate group-based dating violence trajectories and identify the adolescent risk factors that explain membership in each trajectory group. METHOD: Using longitudinal data from the Pathways to Desistance Study, which follows a sample of 1354 serious juvenile offenders from Philadelphia, Pennsylvania and Phoenix, Arizona between mid-adolescence and early adulthood, we estimate group based trajectory models of both emotional dating violence and physical dating violence over a span of five years in young adulthood. We then estimate multinomial logistic regression models to identify theoretically motivated risk factors that predict membership in these groups. RESULTS: We identified three developmental patterns of emotional dating violence: none (33%), low-level (59%) and high-level decreasing (8%). The best-fitting model for physical dating violence also had three groups: none (73%), low-level (24%) and high-level (3%). Race/ethnicity, family and psychosocial variables were among the strongest predictors of both emotional and physical dating violence. In addition, delinquency history variables predicted emotional dating violence and relationship variables predicted physical dating violence. CONCLUSIONS: Dating violence is quite prevalent in young adulthood among serious juvenile offenders. Numerous predictors distinguish between chronic dating violence perpetrators and other groups. These may suggest points of intervention for reducing future violence. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - We report herein a new method for the photoredox activation of boronic esters. Using these reagents, an efficient and high-throughput continuous flow process was developed to perform a dual iridium- and nickel-catalyzed C(sp2 )-C(sp3 ) coupling by circumventing solubility issues associated with potassium trifluoroborate salts. Formation of an adduct with a pyridine-derived Lewis base was found to be essential for the photoredox activation of the boronic esters. Based on these results we were able to develop a further simplified visible light mediated C(sp2 )-C(sp3 ) coupling method using boronic esters and cyano heteroarenes under flow conditions.

AB - AIMS: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support stabilizes patients with cardiogenic shock. Despite improved oxygenation and peripheral circulation, LV unloading may be impeded due to the increased afterload, resulting in a failing static left ventricle and in high mortality. METHODS AND RESULTS: We describe for the first time a large series of patients treated with the combination of VA-ECMO and Impella(r) compared with patients with VA-ECMO only. We retrospectively collected data on patients from two tertiary critical care referral centres. We enrolled 157 patients treated with VA ECMO from January 2013 to April 2015: 123 received VA-ECMO support and 34 had concomitant treatment with VA-ECMO and Impella. A propensity-matching analysis was performed in a 2:1 ratio, resulting in 42 patients undergoing VA-ECMO alone (control group) compared with 21 patients treated with VA-ECMO and Impella. Patients in the VA-ECMO and Impella group had a significantly lower hospital mortality (47% vs. 80%, P < 0.001) and a higher rate of successful bridging to either recovery or further therapy (68% vs. 28%, P < 0.001) compared with VA-ECMO patients. A higher need for continuous veno-venous haemofiltration (48% vs. 19%, P = 0.02) and increased haemolysis (76% vs. 33%, P = 0.004) were reported in the study group due to higher survival. There was no difference in major bleeding rates between the two groups (VA-ECMO and Impella 38% vs. VA-ECMO 29%, P = 0.6). CONCLUSIONS: Concomitant treatment with VA-ECMO and Impella may improve outcome in patients with cardiogenic shock compared with VA-ECMO only. Nevertheless, randomized studies are needed to validate these promising results further.

AB - Astrogliosis is a hallmark of Alzheimer's disease (AD) and may constitute a primary pathogenic component of that disorder. Elucidation of signaling cascades inducing astrogliosis should help characterizing the function of astrocytes and identifying novel molecular targets to modulate AD progression. Here, we describe a novel mechanism by which soluble amyloid-beta modulates beta1-integrin activity and triggers NADPH oxidase (NOX)-dependent astrogliosis in vitro and in vivo. Amyloid-beta oligomers activate a PI3K/classical PKC/Rac1/NOX pathway which is initiated by beta1-integrin in cultured astrocytes. This mechanism promotes beta1 integrin maturation, upregulation of NOX2 and of the glial fibrillary acidic protein (GFAP) in astrocytes in vitro and in hippocampal astrocytes in vivo. Notably, immunochemical analysis of the hippocampi of a triple-transgenic AD mouse model shows increased levels of GFAP, NOX2, and beta1-integrin in reactive astrocytes which correlates with the amyloid beta-oligomer load. Finally, analysis of these proteins in postmortem frontal cortex from different stages of AD (II to V/VI) and matched controls confirmed elevated expression of NOX2 and beta1-integrin in that cortical region and specifically in reactive astrocytes, which was most prominent at advanced AD stages. Importantly, protein levels of NOX2 and beta1-integrin were significantly associated with increased amyloid-beta load in human samples. These data strongly suggest that astrogliosis in AD is caused by direct interaction of amyloid beta oligomers with beta1-integrin which in turn leads to enhancing beta1-integrin and NOX2 activity via NOX-dependent mechanisms. These observations may be relevant to AD pathophysiology. PMID- 27709752 TI - Background factors associated with problem avoidance behavior in healthy partners of breast cancer patients. AB - OBJECTIVE: We evaluated avoidance behaviors of healthy partners of breast cancer patients and sought to (1) describe men's perception of their own avoidance behavior and (2) identify the background factors associated with such behavior. METHODS: An Internet-based survey was conducted, and analysis was performed on the responses of 368 male spouses of female breast cancer patients. RESULTS: Thirty to forty percent of spouses had some type of problem avoidance behavior toward their wives. There was a high correlation (r = 0.70, P < .001) between problem avoidance behavior at the time of diagnosis and subsequent problem behavior (mean follow-up period after diagnosis: 1.3 + 1.1 years). The characteristics of spouses with avoidant behaviors included having wives with recurrence, having wives treated with anticancer drug therapy or total resection, and having their own experience of cancer. Covariance structure analysis revealed 2 factors related to the background of spouses with problem avoidance behavior: (1) having a sense of difficulty in coping (beta = 0.68, P < .001) and (2) having a poor marital relationship (beta = -0.27, P < .001). CONCLUSIONS: Our findings suggest that problem avoidance behavior among healthy male partners of breast cancer patients is common and correlates with difficulty coping and a poor marital relationship. It is important to address both the problem avoidance behavior itself and to support couples early, before this behavior surfaces.

AB - DnaB helicases are bacterial, ATP-driven enzymes that unwind double-stranded DNA during DNA replication. Herein, we study the sequential binding of the "non hydrolysable" ATP analogue AMP-PNP and of single-stranded (ss) DNA to the dodecameric DnaB helicase from Helicobacter pylori using solid-state NMR. Phosphorus cross-polarization experiments monitor the binding of AMP-PNP and DNA to the helicase. 13 C chemical-shift perturbations (CSPs) are used to detect conformational changes in the protein upon binding. The helicase switches upon AMP-PNP addition into a conformation apt for ssDNA binding, and AMP-PNP is hydrolyzed and released upon binding of ssDNA. Our study sheds light on the conformational changes which are triggered by the interaction with AMP-PNP and are needed for ssDNA binding of H. pylori DnaB in vitro. They also demonstrate the level of detail solid-state NMR can provide for the characterization of protein-DNA interactions and the interplay with ATP or its analogues. PMID- 27709754 TI - Imidazole-Aided Native Chemical Ligation: Imidazole as a One-Pot Desulfurization Amenable Non-Thiol-Type Alternative to 4-Mercaptophenylacetic Acid. AB - Various bioactive proteins have been synthesized by native chemical ligation (NCL) and its combination with subsequent desulfurization (e.g., conversion from Cys to Ala). In NCL, excess 4-mercaptophenylacetic acid (MPAA) is generally added to facilitate the reaction. However, co-elution of MPAA with the ligation product during preparative high-performance liquid chromatography sometimes reduces its usefulness. In addition, contamination of MPAA disturbs subsequent desulfurization. Here, we report for the first time that imidazole can be adopted as an alternative to MPAA in NCL using a peptide-alkylthioester. The efficiency of the imidazole-aided NCL (Im-NCL) is similar to that of traditional MPAA-aided NCL. As model cases, we successfully synthesized adiponectin(19-107) and [Ser(PO3 H2 )65 ]-ubiquitin using Im-NCL with a one-pot desulfurization. PMID- 27709755 TI - Microbial eukaryote communities exhibit robust biogeographical patterns along a gradient of Patagonian and Antarctic lakes. AB - Microbial eukaryotes play important roles in aquatic ecosystem functioning. Unravelling their distribution patterns and biogeography provides important baseline information to infer the underlying mechanisms that regulate the biodiversity and complexity of ecosystems. We studied the distribution patterns and factors driving diversity gradients in microeukaryote communities (total, abundant, uncommon and rare community composition) along a latitudinal gradient of lakes distributed from Argentinean Patagonia to Maritime Antarctica using both denaturing gradient gel electrophoresis (DGGE) and high-throughput sequencing (Illumina HiSeq). DGGE and abundant Illumina operational taxonomic units (OTUs) showed both decreasing richness with latitude and significant differences between Patagonian and Antarctic lakes communities. In contrast, total richness did not change significantly across the latitudinal gradient, although evenness and diversity indices were significantly higher in Patagonian lakes. Beta-diversity was characterized by a high species turnover, influenced by both environmental and geographical descriptors, although this pattern faded in the rare community. Our results suggest the co-existence of a 'core biosphere' containing reduced number of abundant/dominant OTUs on which classical ecological rules apply, together with a much larger seedbank of rare OTUs driven by stochastic and reduced dispersal processes. These findings shed new light on the biogeographical patterns and forces structuring inland microeukaryote composition across broad spatial scales.

AB - Pyridoxal-phosphate (PLP)-dependent enzymes catalyse a remarkable diversity of chemical reactions in nature. A1RDF1 from Arthrobacter aurescens TC1 is a fold type I, PLP-dependent enzyme in the class III transaminase (TA) subgroup. Despite sharing 28 % sequence identity with its closest structural homologues, including beta-alanine:pyruvate and gamma-aminobutyrate:alpha-ketoglutarate TAs, A1RDF1 displayed no TA activity. Activity screening revealed that the enzyme possesses phospholyase (E.C. 4.2.3.2) activity towards O-phosphoethanolamine (PEtN), an activity described previously for vertebrate enzymes such as human AGXT2L1, enzymes for which no structure has yet been reported. In order to shed light on the distinctive features of PLP-dependent phospholyases, structures of A1RDF1 in complex with PLP (internal aldimine) and PLP?PEtN (external aldimine) were determined, revealing the basis of substrate binding and the structural factors that distinguish the enzyme from class III homologues that display TA activity. PMID- 27709758 TI - Atom-Efficient Synthesis of Alkynylfluoroborates Using BF3 -Based Frustrated Lewis Pairs. AB - A sterically demanding amine, 1,2,2,6,6-pentamethylpiperidine (PMP), forms a highly reactive Lewis acid-base pair with boron trifluoride. This pair reacts with terminal acetylenes to give the products of C(sp)-H borylation, previously unknown tri- and tetraalkynylboron compounds. Trialkynylfluoroborates can serve as surrogates of alkynyltrifluoroborates for C-C coupling reactions. Using aqueous NaOH, PMP can be recovered from its tetrafluoroborate salt, which is formed as a C-H borylation byproduct. Combining the discovered borylation reactivity with the PMP recovery provides a straightforward and atom-efficient approach to synthetically useful alkynylfluoroborates.

AB - Amorphous Si (a-Si) shows potential advantages over crystalline Si (c-Si) in lithium-ion batteries, owing to its high lithiation potential and good tolerance to intrinsic strain/stress. Herein, porous a-Si has been synthesized by a simple process, without the uses of dangerous or expensive reagents, sophisticated equipment, and strong acids that potential cause environment risks. These porous a-Si particles exhibit excellent electrochemical performances, owing to their porous structure, amorphous nature, and surface modification. They deliver a capacity of 1025 mAh g-1 at 3 A g-1 after 700 cycles. Moreover, the reversible capacity after electrochemical activation, is quite stable throughout the cycling, resulting in a capacity retention about around 88 %. The direct comparison between a-Si and c-Si anodes clearly supports the advantages of a-Si in lithium-ion batteries. PMID- 27709757 TI - Increased basal ganglia binding of 18 F-AV-1451 in patients with progressive supranuclear palsy. AB - BACKGROUND: Progressive supranuclear palsy (PSP) is difficult to diagnose accurately. The recently developed tau PET tracers may improve the diagnostic work-up of PSP. METHODS: Regional tau accumulation was studied using 18 F-AV-1451 PET in 11 patients with PSP and 11 age-matched healthy controls in the Swedish BioFinder study. RESULTS: 18 F-AV-1451 standard uptake volume ratios were significantly higher in the basal ganglia in PSP patients when compared with controls (globus pallidus 1.75 vs 1.50; putamen 1.51 vs 1.35). Retention in the basal ganglia was correlated with age in both groups (r = .43-.78, P < .05). In PSP, we observed a significant correlation between clinical deterioration measured with the PSP rating scale and standard uptake volume ratios in the globus pallidus (r = .74, P < .05). However, no 18 F-AV-1451 retention was observed in the cerebral cortex or white matter of either PSP patients or controls, and autoradiography did not reveal any specific binding of AV-1451 to PSP tau aggregates. CONCLUSION: We found higher 18 F-AV-1451 retention in the basal ganglia of PSP patients when compared with healthy elderly controls, but also increases with age in both controls and patients. As a result of the overlap in retention between diagnostic groups and the age-dependent increase present also in controls, 18 F-AV-1451 PET might not reliably distinguish individual patients with PSP from controls. However, further studies are needed to evaluate whether 18 F-AV-1451 PET might be useful as a progression marker in clinical PSP trials. (c) The Authors.

PMID- 27709760 TI - Photoisomerization of Arylazopyrazole Photoswitches: Stereospecific Excited-State Relaxation. AB - Electronic structure calculations and nonadiabatic dynamics simulations (more than 2000 trajectories) are used to explore the Z-E photoisomerization mechanism and excited-state decay dynamics of two arylazopyrazole photoswitches. Two chiral S1 /S0 conical intersections with associated enantiomeric S1 relaxation paths that are barrierless and efficient (timescale of ca. 50 fs) were found. For the parent arylazopyrazole (Z8) both paths contribute evenly to the S1 excited-state decay, whereas for the dimethyl derivative (Z11) each of the two chiral cis minima decays almost exclusively through one specific enantiomeric S1 relaxation path. To our knowledge, the Z11 arylazopyrazole is thus the first example for nearly stereospecific unidirectional excited-state relaxation.

AB - The reaction of the phosphinidene complex [Cp*P{W(CO)5 }2 ] (1 a) with diphenyldiazomethane leads to [{W(CO)5 }Cp*P=NN{W(CO)5 }=CPh2 ] (2). Compound 2 is a rare example of a phosphadiazadiene ligand (R-P=N-N=CR'R'') complex. At temperatures above 0 degrees C, 2 decomposes into the complex [{W(CO)5 }PCp*{N(H)N=CPh2 )2 ] (3), among other species. The reaction of the pentelidene complexes [Cp*E{W(CO)5 }2 ] (E=P, As) with diazomethane (CH2 NN) proceeds differently. For the arsinidene complex (1 b), only the arsaalkene complex 4 b [{W(CO)5 }2 {eta1:2 -(Cp*)As=CH2 }] is formed. The reaction with the phosphinidene complex (1 a) results in three products, the two phosphaalkene complexes [{W(CO)5 }2 {eta1:2 -(R)P=CH2 }] (4 a: R=Cp*, 5: R=H) and the triazaphosphole derivative [{W(CO)5 }P(Cp*)-CH2 -N{W(CO)5 }=N-N(N=CH2 )] (6 a). The phosphaalkene complex (4 a) and the arsaalkene complex (4 b) are not stable at room temperature and decompose to the complexes [{W(CO)5 }4 (CH2 =E-E=CH2 )] (7 a: E=P, 7 b: E=As), which are the first examples of complexes with parent 2,3 diphospha-1,3-butadiene and 2,3-diarsa-1,3-butadiene ligands. PMID- 27709762 TI - Pharmacological properties of faster-acting insulin aspart vs insulin aspart in patients with type 1 diabetes receiving continuous subcutaneous insulin infusion: A randomized, double-blind, crossover trial. AB - AIM: To evaluate the pharmacological characteristics of faster-acting insulin aspart (faster aspart) compared with insulin aspart (IAsp) during continuous subcutaneous insulin infusion (CSII). METHODS: In this randomized, double-blind, crossover trial, 48 men and women aged 18 to 64 years with type 1 diabetes mellitus (T1DM) received faster aspart and IAsp as a 0.15 U/kg bolus dose via CSII, on top of a basal rate (0.02 U/kg/h), in a glucose clamp setting (target 5.5 mmol/L). RESULTS: After a CSII bolus dose, the pharmacokinetic/pharmacodynamic profiles for faster aspart were left-shifted compared with those for IAsp. For faster aspart vs IAsp, the early glucose lowering effect (area under the curve for glucose infusion rate [GIR]0-30min ) was approximately 2-fold higher (least squares means 24.9 vs 11.4 mg/kg; estimated ratio faster aspart/IAsp 2.18, 95% confidence interval [CI] [1.33; 5.04]; P = .002), onset of glucose-lowering effect (time to early 50% of maximum GIR) occurred 11.1 minutes earlier (41.1 vs 52.3 minutes; 95% CI faster aspart - IAsp [-15.4; -6.9]; P<.001), and offset of glucose-lowering effect (time to late 50% of maximum GIR) occurred 24.0 minutes earlier (214.7 vs 238.7 minutes; 95% CI [-38.9; -9.1]; P=.002). Likewise, significantly greater early exposure and significantly earlier onset and offset of exposure were observed for faster aspart vs IAsp. Faster aspart and IAsp were both well tolerated. CONCLUSIONS: In patients with T1DM using CSII, faster aspart better mimics the endogenous prandial insulin secretion and action than does IAsp. Faster aspart therefore has the potential to provide clinical benefits over current rapid-acting insulins in the insulin pump setting. PMID- 27709763 TI - C(sp3 )-H Oxidative Addition and Transfer Hydrogenation Chemistry of a Titanium(II) Synthon: Mimicry of Late-Metal Type Reactivity. AB - Two-electron reduction of the TiIV compound (ket guan)(ImDipp N)Ti(OTf)2 (3) gives the arene-masked complex (ket guan)(eta6 -ImDipp N)Ti (1) in excellent yield. Upon standing in solution, 1 converts to a TiIV metallacycle (4) through dehydrogenation of a pendant isopropyl group. Spectroscopic evidence shows this transformation initially proceeds via the oxidative addition of a C(sp3 )-H bond and can be reversed upon exposure of 4 to H2 . Interestingly, treatment of 1 with cyclohexene gives cyclohexane and 4 via a titanium-mediated transfer hydrogenation reaction, a process that can be extended to catalytically hydrogenate other unsaturated hydrocarbons under mild conditions. These results, rare for the early-metals, suggest 1 possesses chemical characteristics reminiscent of noble, late-metals. PMID- 27709764 TI - A Novel Pseudo-Protein-Based Biodegradable Nanomicellar Platform for the Delivery of Anticancer Drugs. AB - Amino acid-based poly(ester amide)s are a new family of biodegradable polymers that exhibit "pseudo-protein" characteristics and the structural varieties of poly(ester amide)s make them hold great potential in multiple biomedical applications. In this study, a lysine-phenylalanine-based pseudo-protein is developed as the self-assembled nanomicellar carrier for efficient delivery of doxorubicin. The lysine moieties from the pseudo-protein provide available sites for further functionalization, and methylcoumarin is introduced for easy and photocontrollable crosslinking, to effectively improve the micellar stability in serum containing environment and against dilution. However, photocrosslinks do not bring in any barrier for the intracellular release of doxoubicin. Doxorubicin release is significantly accelerated by proteolytic enzyme, due to the biodegradability of pseudo-protein micelles. In addition, pseudo-protein delivery system exhibits unique interactions with HCT116 human colon cancer cells. Doxorubicin loaded in pseudo-protein micelles colocalizes with mitochondria and endolysosomes, while free doxorubicin is distributed only in the nuclei. Doxorubicin-loaded pseudo-protein micelles stimulate increased level of intracellular reactive oxygen species and mitochondrial damage. Free doxorubicin induces conditional apoptosis in HCT116 cells between 0.5* 10-6 and 2 * 10-6 m, while DOX loaded in pseudo-protein micelles induces apoptosis over a higher/broader concentration range (2 * 10-6 -10 * 10-6 m).

AB - Proton-coupled electron-transfer oxidation of a RuII -OH2 complex, having an N heterocyclic carbene ligand, gives a RuIII -O. species, which has an electronically equivalent structure of the RuIV =O species, in an acidic aqueous solution. The RuIII -O. complex was characterized by spectroscopic methods and DFT calculations. The oxidation state of the Ru center was shown to be close to +3; the Ru-O bond showed a lower-energy Raman scattering at 732 cm-1 and the Ru-O bond length was estimated to be 1.77(1) A. The RuIII -O. complex exhibits high reactivity in substrate oxidation under catalytic conditions; particularly, benzaldehyde and the derivatives are oxidized to the corresponding benzoic acid through C-H abstraction from the formyl group by the RuIII -O. complex bearing a strong radical character as the active species. PMID- 27709767 TI - Reversible Dihydrogen Activation by Reduced Aryl Boranes as Main-Group Ambiphiles. AB - A new approach to main-group H2 activation combining concepts of transition-metal and frustrated Lewis pair chemistry is reported. Ambiphilic, metal-like reactivity toward H2 can be conferred to 9,10-dihydro-9,10-diboraanthracene (DBA) acceptors by the injection of two electrons. The resulting [DBA]2- ions cleave the H-H bond with the formation of hydridoborates under moderate conditions (T=50 100 degrees C; p<1 atm). Depending on the boron-bonded substituents R, the addition is either reversible (R=C=CtBu) or irreversible (R=H). The reaction rate is strongly influenced by the nature and the coordination behavior of the countercation (Li+ slower than K+ ). Quantum-chemical calculations support the experimental observations and suggest a concerted, homolytic addition of H2 across both boron atoms. As proven by the successful conversion of Me3 SiCl into Me3 SiH, the system Li2 [DBA]/H2 appears generally relevant for the hydrogenation of element-halide bonds.

AB - Surface plasmon resonance (SPR) is one of the most powerful label-free methods to determine the kinetic parameters of molecular interactions in real time and in a highly sensitive way. Penicillin-binding proteins (PBPs) are peptidoglycan synthesis enzymes present in most bacteria. Established protocols to analyze interactions of PBPs by SPR involve immobilization to an ampicillin-coated chip surface (a beta-lactam antibiotic mimicking its substrate), thereby forming a covalent complex with the PBPs transpeptidase (TP) active site. However, PBP interactions measured with a substrate-bound TP domain potentially affect interactions near the TPase active site. Furthermore, in vivo PBPs are anchored in the inner membrane by an N-terminal transmembrane helix, and hence immobilization at the C-terminal TPase domain gives an orientation contrary to the in vivo situation. We designed a new procedure: immobilization of PBP by copper-free click chemistry at an azide incorporated in the N terminus. In a proof-of-principle study, we immobilized Escherichia coli PBP1B on an SPR chip surface and used this for the analysis of the well-characterized interaction of PBP1B with LpoB. The site-specific incorporation of the azide affords control over protein orientation, thereby resulting in a homogeneous immobilization on the chip surface. This method can be used to study topology-dependent interactions of any (membrane) protein.

AB - A unique composite of the copper-based metal-organic framework (Cu-benzene tricarboxylic acid (BTC)) with oxidized graphitic carbon nitride nanospheres is synthesized. For comparison, a hybrid material consisting of g-C3 N4 and Cu-BTC is also obtained. Their surface features are analyzed using Fourier transform infrared spectroscopy, X-ray diffraction, sorption of nitrogen, thermal analysis, scanning electron microscopy, photoluminescence, and diffuse reflectance UV-Vis spectroscopy. The results suggest that the formed nanospheres of oxidized g-C3 N4 act as linkers between the copper sites, playing a crucial role in the composite building process. Their incorporation to the Cu-BTC framework causes the development of new mesoporosity. Remarkable alterations in the optical properties, as a result of the coordination of oxygen containing functional groups of the oxidized graphitic carbon nitride to the copper atoms of the framework, suggest an increase in photoreactivity. On the other hand, for the hybrid material consisting of Cu-BTC and g-C3 N4 , the unaltered pore volume and optical properties support the formation of a physical mixture rather than of a composite. The tests on reactive adsorption and detoxification of G-series organophosphate nerve agent surrogate show the enhanced performance of the composite as catalysts and photocatalyst in visible light.

AB - An approach to transforming amorphous organic networks into crystalline covalent organic frameworks (COFs) with retention of the colloidal nanosize and uniform morphology is presented. Specifically, Fe3 O4 nanoclusters are encapsulated by a disordering polyimine network via the Schiff-base reaction. The formed imine bonds could be reconstructed under thermodynamic control to reform the polyimine networks into imine-linked COFs in situ. Such a core-shell microsphere exhibits the uniform size and spherical shape, controllable COF shell thickness, accessible surface modification, and improved solution dispersibility as well as maintenance of high surface area, periodic micropores, and superior magnetic responsiveness. Additionally, the photothermal conversion effect is demonstrated for the first time on the nanoCOF layers upon exposure to near infrared light, providing convincing evidence for potential use in phototherapy. PMID- 27709770 TI - Health Professionals' Perceptions of the Effects of Exercise on Joint Health in Rheumatoid Arthritis Patients. AB - OBJECTIVES: Although exercise is an important factor in the management of rheumatoid arthritis (RA), research indicates that patients perceive that health professionals (HPs) are uncertain about the place of exercise in treatment and its relationship with joint damage. The present study investigated the perceptions of HPs regarding the effects of exercise on joint health in RA patients. METHODS: A questionnaire investigating perceptions of exercise and joint health was distributed via professional networks and websites. Confirmatory factor analysis (CFA) was used to analyse questionnaire data and develop a focus group interview guide. Focus groups were conducted with multidisciplinary teams (MDTs) of rheumatology HPs and analysed using framework analysis. RESULTS: A total of 137 rheumatology HPs (95 female; 27-65 years of age) completed questionnaires. CFA showed that a four-factor model provided a marginally acceptable fit. Analysis of four focus groups (n = 24; 19 female; 30-60 years of age) identified five themes relating to HPs' perceptions of exercise and joint health in RA patients: 'Exercise is beneficial', 'Concerns about damage to joints', 'Patients have barriers to exercise', 'HP knowledge differs' and 'Patients may think service delivery is vague'. CONCLUSIONS: HPs were highly aware of the benefits and importance of exercise for RA patients. However, to remove the patient perception that HPs lack certainty and clarity regarding exercise it is important to ensure: (i) consistent promotion of exercise across the whole MDT; (ii) clear provision of information regarding rest, joint protection and exercise; (iii) HP education to ensure consistent, accurate knowledge, and understanding of the potential for conflicting advice when promoting exercise as part of an MDT.

AB - Metal-phosphinito-phosphinous acid complexes are interesting catalysts exhibiting unique reactivities. In this account, we intend to provide a clear overview of palladium- and platinum-phosphinito-phosphinous acid complexes, their preparation from secondary phosphine oxides, and their applications in catalysis. They have been mainly used to develop [2+1] cycloadditions to afford methylenecyclopropane derivatives using norbornenes and various alkynes as partners. As a function of the catalyst, the reaction conditions, or the nature of the reagents, different synthetic transformations have been observed: [2+1] cycloadditions, giving rise to either alkylidenecyclopropanes or vinylidenecyclopropanes; tandem [2+1]/[3+2] cycloadditions, and so forth. The mechanisms of these reactions have been studied to rationalize the different reactivities observed.

AB - Estrone molecularly imprinted polymers were synthesized through the self polymerization of dopamine on the surface of silica gels, which had the characteristics of mild polymerization conditions, simple reaction procedure and good specific recognition ability for estrone. The estrone molecularly imprinted polymers were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, elemental analysis and nitrogen adsorption-desorption tests. The characterization confirmed that the imprinted polymers were successfully grafted on the surface of silica gels. Through investigating the adsorption performance, the prepared estrone molecularly imprinted polymers exhibited high adsorption capacity, fast mass transfer, as well as excellent selectivity toward estrone. The estrone molecularly imprinted polymers as the solid-phase extraction adsorbent coupled with high-performance liquid chromatography was developed to determine estrone from the milk samples. The developed estrone molecularly imprinted polymer solid phase extraction with high-performance liquid chromatography method exhibited satisfactory specificity, precision, accuracy and good linearity relationship in the range of 0.2-20 MUg/mL. The developed method is simple, fast, effective and high specificity method and it provides a new method to detect the residues of estrone in animal foods.

AB - Tunable plasmonic platforms are important for a variety of applications such as photovoltaics, LED's, optoelectronics, medical research, and biosensors. In particular, development of label-free plasmonic biosensors is one of the key research areas that utilizes plasmonic nanostructures for detection of biologically relevant molecules at low concentrations. The authors have developed a cost-effective, fast, and lithography-free method to fabricate transparent fused silica nanocylinders. The technique allows tuning of nanocylinder height, diameter, and density and can be scaled to large surface areas, such as 8 in. wafers. The authors demonstrate that gold coated nanocylinders support localized surface plasmon resonances (LSPR) from visible to near infrared wavelengths. The plasmonic platform can be characterized as suspended gold nanorings and exhibits a sensitivity of 658 nm RIU-1 with a figure-of-merit of 10, comparable to other state-of-the-art LSPR sensing platforms that utilize more complex nanofabrication pathways. It was observed that the LSPR peak positions can be controlled by varying the geometry of the nanocylinders. The authors illustrate surface functionalization, biosensing, and surface regeneration properties of the platform using thiols and detection of bovine serum albumin (BSA). The observed LSPR shifts for 11-mercaptoundecanoic acid and BSA was 12 and 26 nm, respectively.

Our recent groundwork allowed us to formulate the concept of a portable bioaerosol monitor, which needs to be light, user friendly, reliable and capable of detecting airborne pathogens within 1-1.5 h on the spot. METHODS AND RESULTS: Conceptually, the event of a bioaerosol concentration burst is determined by triggers to commence the representative air sampling with sequential real-time polymerase chain reaction (PCR) confirmation of the targeted micro-organism present in the air. To minimize reagent consumption and idle running of the technology, an event of a bioaerosol burst is confirmed by three parameters: aerosol particle size, concentration and composition. Only particle sizes above 200 nm attract interest in the bioaerosol. Only an elevated aerosol concentration above the threshold (background aerosol concentration) is a signal to commence the analytical procedure. The combination of our previously developed personal bioaerosol sampler, aerosol particle counter based trigger and portable real-time PCR device formed the basis of the bioaerosol monitoring technology. The portable real-time PCR device was advanced to provide internally controlled detection, significantly reducing false-positive alarms. CONCLUSIONS: The technique is capable of detecting selected airborne micro-organisms on the spot within 30-80 min, depending on the genome organization of the particular strain. SIGNIFICANCE AND IMPACT OF THE STUDY: Due to recent outbreaks of infectious airborne diseases and the continuing threat of intentionally released bioaerosol attacks, investigations into the possibility of the early and reliable detection of pathogenic micro-organisms in the air is becoming increasingly important. The proposed technology consisting of a bioaerosol sampler, technology trigger and PCR device is capable of detecting selected airborne micro-organisms on the spot within a short time period.

AB - Rational design and development of new-generation photocatalysts with high hydrogen evolution activity is recognized as an effective strategy to settle energy crisis. To this regard, hybrid photocatalysts of Au quantum dots embedded in rimous cadmium sulfide nanospheres are synthesized by using a simple hydrothermal process followed by photoreduction. The rimous cadmium sulfide nanospheres with rough surface and irregular fissures greatly strengthen their adhesion and interaction with Au quantum dots, which effectively facilitates the separation, restrains the recombination, and accelerates the consumption of photoinduced electron-hole pairs. Impressively, the highest photocatalytic activity for hydrogen generation (601.2 MUmol h-1 g-1 ) and organic pollutant degradation (100% degradation in 80 min) is obtained by adjusting the Au mass loading to achieve uniform distribution. This work paves new way to the exploitation of highly efficient metal/semiconductor hybrid photocatalysts for clean energy generation and environment restoration.

AB - Transient abnormal myelopoesis is mostly self-resolving and has a good prognosis, but some patients subsequently die of liver fibrosis. We report the case of an infant with Down syndrome who developed life-threatening liver fibrosis at the same time as the blasts were about to disappear. This patient also had a marked increase in eosinophils, which were possibly harboring a GATA1 mutation and were expressing a high level of platelet-derived growth factor-B mRNA; these may have been involved in the development of liver fibrosis. Low-dose cytosine arabinoside therapy effectively treated both hypereosinophilia and liver fibrosis.

AB - Silicon is used as a prominent case to demonstrate the dramatic effects of helium ion microscope nanofabrication. Structurally, a submicrometer Si pillar can turn completely amorphous at He+ doses typically used for micromachining, forming nanobubbles at higher doses. In terms of mechanical properties, the flow stress decreases markedly with increasing dosage, and the softened amorphous Si exhibits spread-out plastic flow. PMID- 27709780 TI - Construction of Asymmetrical Hexameric Biomimetic Motors with Continuous Single Directional Motion by Sequential Coordination. AB - The significance of bionanomotors in nanotechnology is analogous to mechanical motors in daily life. Here the principle and approach for designing and constructing biomimetic nanomotors with continuous single-directional motion are reported. This bionanomotor is composed of a dodecameric protein channel, a six pRNA ring, and an ATPase hexamer. Based on recent elucidations of the one-way revolving mechanisms of the phi29 double-stranded DNA (dsDNA) motor, various RNA and protein elements are designed and tested by single-molecule imaging and biochemical assays, with which the motor with active components has been constructed. The motor motion direction is controlled by three operation elements: (1) Asymmetrical ATPase with ATP-interacting domains for alternative DNA binding/pushing regulated by an arginine finger in a sequential action manner. The arginine finger bridges two adjacent ATPase subunits into a non covalent dimer, resulting in an asymmetrical hexameric complex containing one dimer and four monomers. (2) The dsDNA translocation channel as a one-way valve. (3) The hexameric pRNA ring geared with left-/right-handed loops. Assessments of these constructs reveal that one inactive subunit of pRNA/ATPase is sufficient to completely block motor function (defined as K = 1), implying that these components work sequentially based on the principle of binomial distribution and Yang Hui's triangle. PMID- 27709781 TI - Activation of ATP-sensitive potassium channels facilitates the function of human endothelial colony-forming cells via Ca2+ /Akt/eNOS pathway. AB - Accumulating data, including those from our laboratory, have shown that the opening of ATP-sensitive potassium channels (KATP ) plays a protective role in pulmonary vascular diseases (PVD). As maintainers of the endothelial framework, endothelial colony-forming cells (ECFCs) are considered excellent candidates for vascular regeneration in cases of PVD. Although KATP openers (KCOs) have been demonstrated to have beneficial effects on endothelial cells, the impact of KATP on ECFC function remains unclear. Herein, this study investigated whether there is a distribution of KATP in ECFCs and what role KATP play in ECFC modulation. By human ECFCs isolated from adult peripheral blood, KATP were confirmed for the first time to express in ECFCs, comprised subunits of Kir (Kir6.1, Kir6.2) and SUR2b. KCOs such as the classical agent nicorandil (Nico) and the novel agent iptakalim (Ipt) notably improved the function of ECFCs, promoting cell proliferation, migration and angiogenesis, which were abolished by a non selective KATP blocker glibenclamide (Gli). To determine the underlying mechanisms, we investigated the impacts of KCOs on CaMKII, Akt and endothelial nitric oxide synthase pathways. Enhanced levels were detected by western blotting, which were abrogated by Gli. This suggested an involvement of Ca2+ signalling in the regulation of ECFCs by KATP . Our findings demonstrated for the first time that there is a distribution of KATP in ECFCs and KATP play a vital role in ECFC function. The present work highlighted a novel profile of KATP as a potential target for ECFC modulation, which may hold the key to the treatment of PVD.

AB - A rapid and simple method for the extraction and preconcentration of ceftazidime in aqueous samples has been developed using dispersive liquid-liquid microextraction followed by high-performance liquid chromatography analysis. The extraction parameters, such as the volume of extraction solvent and disperser solvent, salt effect, sample volume, centrifuge rate, centrifuge time, extraction time, and temperature in the dispersive liquid-liquid microextraction process, were studied and optimized with the experimental design methods. Firstly, for the preliminary screening of the parameters the taguchi design was used and then, the fractional factorial design was used for significant factors optimization. At the optimum conditions, the calibration curves for ceftazidime indicated good linearity over the range of 0.001-10 MUg/mL with correlation coefficients higher than the 0.98, and the limits of detection were 0.13 and 0.17 ng/mL, for water and urine samples, respectively. The proposed method successfully employed to determine ceftazidime in water and urine samples and good agreement between the experimental data and predictive values has been achieved.

AB - Erinacine A, a major active component of a diterpenoid derivative isolated from Hericium erinaceus mycelium, has been demonstrated to exert anticancer effects. Herein, we present an investigation of the molecular mechanism of erinacine A induction associated with cancer cells' aggressive status and death. A proteomic approach was used to purify and identify the differentially expressed proteins following erinacine A treatment and the mechanism of its action in apoptotic and the targets of erinacine A. Our results demonstrate that erinacine A treatment of HCT-116 and DLD-1 cells increased cell cytotoxicity and reactive oxygen species (ROS) production as well as decreased cell proliferation and invasiveness. Ten differentially displayed proteins were determined and validated in vitro and in vivo between the erinacine A-treated and untreated groups. In addition, erinacine A time-dependent induction of cell death and inhibitory invasiveness was associated with sustained phosphorylation of the PI3K/mTOR/p70S6K and ROCK1/LIMK2/Cofilin pathways. Furthermore, we demonstrated that erinacine A induced HCT-116 and DLD-1 cells viability and anti-invasion properties by up regulating the activation of PI3K/mTOR/p70S6K and production of ROS. Experiments involving specific inhibitors demonstrated that the differential expression of cofilin-1 (COFL1) and profilin-1 (PROF1) during erinacine A treatment could be involved in the mechanisms of HCT-116 and DLD-1 cells death and decreased aggressiveness, which occurred via ROCK1/LIMK2/Cofilin expression, with activation of the PI3K/mTOR/p70S6K signalling pathway. These findings elucidate the mechanism of erinacine A inhibiting the aggressive status of cells by activating PI3K/mTOR/p70S6K downstream signalling and the novel protein targets COF1 and PROF1; this could be a good molecular strategy to limit the aggressiveness of CRC cells. PMID- 27709784 TI - Morin hydrate promotes inner ear neural stem cell survival and differentiation and protects cochlea against neuronal hearing loss. AB - We aimed to investigate the effect of morin hydrate on neural stem cells (NSCs) isolated from mouse inner ear and its potential in protecting neuronal hearing loss. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) and bromodeoxyuridine incorporation assays were employed to assess the effect of morin hydrate on the viability and proliferation of in vitro NSC culture. The NSCs were then differentiated into neurons, in which neurosphere formation and differentiation were evaluated, followed by neurite outgrowth and neural excitability measurements in the subsequent in vitro neuronal network. Mechanotransduction of cochlea ex vivo culture and auditory brainstem responses threshold and distortion product optoacoustic emissions amplitude in mouse ototoxicity model were also measured following gentamicin treatment to investigate the protective role of morin hydrate against neuronal hearing loss. Morin hydrate improved viability and proliferation, neurosphere formation and neuronal differentiation of inner ear NSCs, and promoted in vitro neuronal network functions. In both ex vivo and in vivo ototoxicity models, morin hydrate prevented gentamicin-induced neuronal hearing loss. Morin hydrate exhibited potent properties in promoting growth and differentiation of inner ear NSCs into functional neurons and protecting from gentamicin ototoxicity. Our study supports its clinical potential in treating neuronal hearing loss. PMID- 27709785 TI - Plasmonic Metasurfaces Based on Nanopin-Cavity Resonator for Quantitative Colorimetric Ricin Sensing. AB - In view of the toxic potential of a bioweapon threat, rapid visual recognition and sensing of ricin has been of considerable interest while remaining a challenging task up to date. In this study, a gold nanopin-based colorimetric sensor is developed realizing a multicolor variation for ricin qualitative recognition and analysis. It is revealed that such plasmonic metasurfaces based on nanopin-cavity resonator exhibit reflective color appearance, due to the excitation of standing-wave resonances of narrow bandwidth in visible region. This clear color variation is a consequence of the reflective color mixing defined by different resonant wavelengths. In addition, the colored metasurfaces appear sharp color difference in a narrow refractive index range, which makes them especially well-suited for sensing applications. Therefore, this antibody functionalized nanopin-cavity biosensor features high sensitivity and fast response, allowing for visual quantitative ricin detection within the range of 10 120 ng mL-1 (0.15 * 10-9 -1.8 * 10-9 m), a limit of detection of 10 ng mL-1 , and the typical measurement time of less than 10 min. The on-chip integration of such nanopin metasurfaces to portable colorimetric microfluidic device may be envisaged for the quantitative studies of a variety of biochemical molecules. PMID- 27709787 TI - Trace determination of organophosphate esters in environmental water samples with an ionogel-based nanoconfined ionic liquid fiber coating for solid-phase microextraction with gas chromatography and flame photometric detection. AB - Organophosphate esters, widely used as flame retardants and plasticizers, are regarded as a class of emerging pollutants. In this work, a novel approach was developed for the fabrication of a solid-phase microextraction fiber by using hybrid silica-based materials with immobilized ionic liquids with sol-gel technology, and the prepared solid-phase microextraction fiber was then coupled with gas chromatography and flame photometric detection for the analysis of six organophosphate esters. The high loading of 1-hexadecyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide was confined within the hybrid network. The developed solid-phase microextraction fiber possesses a coating thickness of ~35 MUm with good thermal stability and long lifetime. The parameters affecting the extraction efficiency such as extraction time, temperature, pH, and ionic strength of the sample solution were optimized. Under the optimized conditions, the limits of detection were in the range of 0.04-0.95 MUg L-1 , and the precision of the method assessed with repeatability and reproducibility of (RSD%) ?13 and ?29%, respectively. The proposed method was successfully applied to determine the six organophosphate esters in three real water samples, with recoveries in the range of 64.8-125.4% at two different spiking concentration levels. As a result, the proposed method demonstrated its potential for application in trace determination of organophosphate esters in actual water samples. PMID- 27709786 TI - RGB and HSV quantitative analysis of autofluorescence bronchoscopy used for characterization and identification of bronchopulmonary cancer. AB - Autofluorescence bronchoscopy (AFB) shows good sensitivity in detecting dysplasia and bronchopulmonary cancer. However, the poor specificity of AFB would lead to excessive biopsy. The aim of the study is to establish a more effective quantitative method (optimal identification index and reference value) for characterizing the AFB images within the region of interest and discuss AFB's significance in the diagnosis of central-type lung cancer. A total of 218 suspected lung cancer patients were enrolled in this study. A quantitative analysis based on color space (red, green, blue[RGB] and HSV system) was conducted and the result was compared with the final diagnosis obtained by the pathology of biopsy. Cases were divided into different groups according to the pathological diagnosis of normal bronchial mucosa, inflammation, low-grade preinvasive (LGD), high-grade preinvasive (HGD), and invasive cancer. Quantitative analyses in multi-color spaces for the lesions showed by AFB images were conducted by software MATLAB. Finally, there is statistical significance among the different groups in some parameter in RGB and HSV system. So, both RGB and HSV quantitative analysis of autofluorescence bronchoscopy are useful to define benign and malignant diseases, which can objectively guide the bronchoscopist in selecting sites for biopsy with good pathologic correlation. PMID- 27709788 TI - Micro- and Nano-Liquid Phases Coexistent with Ice as Separation and Reaction Media. AB - Ice has a variety of scientifically interesting features, some of which have not been reasonably interpreted despite substantial efforts by researchers. Most chemical studies of ice have focused on the elucidation of its physicochemical nature and its roles in the natural environment. Ice often contains impurities, such as salts, and in such cases, a liquid phase coexists with solid ice over a wide temperature range. This impure ice also acts as a cryoreactor, governing the circulation of chemical species of environmental importance. Reactions and phenomena occurring in this liquid phase show features different from those seen in normal bulk aqueous solutions. In the present account, we discuss the chemical characteristics of the liquid phase that develops in a frozen aqueous phase and show how novel analytical systems can be designed based on he features of the liquid phase which are predictable in some cases but unpredictable in others. PMID- 27709790 TI - Erratum. PMID- 27709789 TI - Comprehensive study of the macropore and mesopore size distributions in polymer monoliths using complementary physical characterization techniques and liquid chromatography. AB - Poly(styrene-co-divinylbenzene) monolithic stationary phases with two different domain sizes were synthesized by a thermally initiated free-radical copolymerization in capillary columns. The morphology was investigated at the meso- and macroscopic level using complementary physical characterization techniques aiming at better understanding the effect of column structure on separation performance. Varying the porogenic solvent ratio yielded materials with a mode pore size of 200 nm and 1.5 MUm, respectively. Subsequently, nano liquid chromatography experiments were performed on 200 MUm id * 200 mm columns using unretained markers, linking structure inhomogeneity to eddy dispersion. Although small-domain-size monoliths feature a relatively narrow macropore-size distribution, their homogeneity is compromised by the presence of a small number of large macropores, which induces a significant eddy-dispersion contribution to band broadening. The small-domain size monolith also has a relatively steep mass transfer term, compared to a monolith containing larger globules and macropores. Structural inhomogeneity was also studied at the mesoscopic level using gas adsorption techniques combined with the non-local-density-function-theory. This model allows to accurately determine the mesopore properties in the dry state. The styrene-based monolith with small domain size has a distinctive trimodal mesopore distribution with pores of 5, 15, and 25 nm, whereas the monolith with larger feature sizes only contains mesopores around 5 nm in size. PMID- 27709792 TI - Investigating the work-family conflict and health link: Repetitive thought as a mechanism. AB - Research is needed to investigate mechanisms linking work-family conflict to poor health in working adults. We took a novel approach to build on extant studies by testing a potential mechanism in these associations - repetitive thought. Data came from a sample of 203 partnered working adults. There were significant direct effects of work-family conflict with lower life satisfaction, positive affect, and perceived health as well as greater fatigue. As for total effects, work family conflict was significantly associated with all health outcomes - life satisfaction, positive affect, negative affect, fatigue, perceived health, and chronic health conditions - in the expected directions through repetitive thought. This study provides support that repetitive thought is one potential mechanism of how work-family conflict can take a toll on psychological and physical health. Findings are discussed in relation to improving workplace policies to improve the health of working adults managing work-family conflict. PMID- 27709793 TI - PD-1 expression on the surface of peripheral blood CD4+ T cell and its association with the prognosis of patients with diffuse large B-cell lymphoma. AB - The aim of the study was to investigate the relationship between PD-1 expression on the surface of CD4+ T cells and prognosis of patients with diffuse large B cell lymphoma (DLBCL). Sixty patients who were newly diagnosed with DLBCL and 39 healthy controls were enrolled. In CD4+ T cells of DLBCL patients, the median MFI of PD-1 were 541.5 (range: 348.25-758.75), significantly higher than 250 (range: 211-326) in healthy controls (P < 0.001). The ZAP70, PI3K, and NFAT mRNA expression levels of patients were 0.47, 0.47, and 0.62 times, respectively, of those of the healthy controls (P < 0.05). In patients with the percentage of PD-1 on CD4+ T cells >=30.25%, their EFS and OS were significantly lower than patients with PD-1+ CD4+ T cells <30.25% (P < 0.05). The possible explanation is that high PD-1 expression on CD4+ cells of DLBCL patients may impair T-cell function and thus contribute to poor prognosis. There was no relationship between PD-1 surface expression on CD4+ T cells and PD-1 expression within the biopsy of tumor microenvironments from DLBCL patients. PMID- 27709794 TI - Addition of a dipeptidyl peptidase-4 inhibitor, sitagliptin, to ongoing therapy with the glucagon-like peptide-1 receptor agonist liraglutide: A randomized controlled trial in patients with type 2 diabetes. AB - AIM: To determine whether the addition of sitagliptin to pre-existing therapy with liraglutide changes glycaemic excursions after a mixed meal. METHODS: A total of 16 patients with type 2 diabetes treated with metformin and liraglutide (1.2 mg/d for >=2 weeks) were randomized (sealed envelopes), within a cross-over design, to be studied on two occasions, after an overnight fast, with (1) sitagliptin (100 mg orally) and (2) placebo (patients and care givers blinded) administered 60 minutes before a mixed meal, or vice versa. Glucose excursions (incremental area under the curve [AUC]; primary endpoint) and insulin, C peptide, glucagon and incretin concentrations were measured. The study setting was a metabolic study unit at a specialized diabetes hospital. RESULTS: All 16 patients completed the study and were analysed. Glucose (AUCglucose 319 +/- 30 [placebo] vs 315 +/- 18 mmol.L-1 .min-1 [sitagliptin], Delta 7 [95% confidence interval -50 to 63] mmol.L-1 .min-1 ), insulin, C-peptide and glucagon concentrations were not affected significantly by sitagliptin treatment ( P = .60 1.00). Intact glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) concentrations were augmented by sitagliptin, by 78.4% and 90.2%, respectively (both P < .0001). The influence of sitagliptin treatment on incretin plasma concentrations was similar to previously published results obtained in patients with type 2 diabetes on metformin treatment only. CONCLUSIONS: Sitagliptin, in patients already treated with a GLP-1 receptor agonist (liraglutide), increased intact GLP-1 and GIP concentrations, but with marginal, non-significant effects on glycaemic control. GLP-1 receptors have probably been maximally stimulated by liraglutide. Our findings do not support combination treatment with GLP-1 receptor agonists and DPP-4 inhibitors, but longer-term trials are needed to support clinical recommendations.

PMID- 27709795 TI - Radiofrequency ablation versus stereotactic body radiotherapy for small hepatocellular carcinoma: a Markov model-based analysis. AB - The aim of this study is to compare radiofrequency ablation (RFA) with stereotactic body radiotherapy (SBRT) for hepatocellular carcinomas (HCC) smaller than 3 cm. A Markov cohort model was developed to simulate a cohort of patients aged 60-65 years with small HCCs who had undergone either RFA or SBRT and were followed up over their remaining life expectancy. The inclusion criteria were: (1) HCC <=3 cm in diameter with <= 3 nodules; (2) absence of extrahepatic metastasis or portal/hepatic vein invasion; (3) Child-Pugh Class A or B. Twenty thousand virtual patients were randomly assigned to undergo RFA or SBRT. Predicted life expectancy was 6.452 and 6.371 years in the RFA and SBRT groups, respectively. The probability distributions of the expected overall survival were nearly identical. The 95% confidence intervals were 6.25-6.66 and 6.17-6.58 years for RFA and SBRT, respectively. The difference between RFA and SBRT was insignificant (P = 0.2884). Two-way sensitivity analysis demonstrated that if the tumor is 2-3 cm, SBRT is the preferred treatment option. Our Markov model has shown that expected overall survival of SBRT is nearly identical to RFA in HCCs smaller than 3 cm, but SBRT may have an advantage for tumors 2 cm and larger. A randomized trial is required to confirm these findings. PMID- 27709797 TI - Homoharringtonine combined with aclarubicin and cytarabine synergistically induces apoptosis in t(8;21) leukemia cells and triggers caspase-3-mediated cleavage of the AML1-ETO oncoprotein. AB - Homoharringtonine combined with aclarubicin and cytarabine (HAA) is a highly effective treatment for acute myeloid leukemia (AML), especially for t(8;21) AML. However, the underlying mechanisms by which HAA kills t(8;21) AML cells remain unclear. In this study, SKNO-1 and Kasumi-1 cells with t(8;21) were used. Compared with individual or pairwise administration of homoharringtonine, aclarubicin, or cytarabine, HAA showed the strongest inhibition of growth and induction of apoptosis in SKNO-1 and Kasumi-1 cells. HAA caused cleavage of the AML1-ETO (AE) oncoprotein to form truncated AE (DeltaAE). Pretreatment with the caspase-3 inhibitor caspase-3 inhibitor Q-DEVD-OPh (QDO) not only suppressed HAA induced apoptosis but also abrogated the cleavage of AE and generation of DeltaAE. These results suggest that HAA synergistically induces apoptosis in t(8;21) leukemia cells and triggers caspase-3-mediated cleavage of the AML1-ETO oncoprotein, thus providing direct evidence for the strong activity of HAA toward t(8;21) AML. PMID- 27709798 TI - The E3 ubiquitin ligase RNF135 regulates the tumorigenesis activity of tongue cancer SCC25 cells. AB - Several E3 ubiquitin ligases have been confirmed that they are related to the tumorigenesis. This study aims to find the tongue cancer-related E3 ubiquitin ligase. The E3 ubiquitin ligase library was screened. The effect of candidate molecule on tongue cancer was validated through cell viability, cell proliferation, colony formation, invasive assay in vitro, and the xenograft model in vivo. The E3 ubiquitin ligase RNF135 significantly promoted the expression of PTEN and TP53 in SCC25 cells. The overexpression of RNF135 inhibited the viability, proliferation, and invasion of SCC25 cells. Knockdown of RNF135 had the opposite effects. Furthermore, RNF135 regulates the tumorigenesis activity of SCC25 cells in vivo. Our results demonstrated that RNF135 had the potential to affect the development of the tongue cancer in vitro. The further in vivo study is helpful to fully understand the role of it. PMID- 27709800 TI - An implicit solver for 1D arterial network models. AB - In this study, the 1D blood flow equations are solved using a newly proposed enhanced trapezoidal rule method (ETM), which is an extension to the simplified trapezoidal rule method. At vessel junctions, the conservation of mass and conservation of total pressure are held as system constraints using Lagrange multipliers that can be physically interpreted as external flow rates. The ETM scheme is compared with published arterial network benchmark problems and a dam break problem. Strengths of the ETM scheme include being simple to implement, intuitive connection to lumped parameter models, and no restrictive stability criteria such as the Courant-Friedrichs-Lewy (CFL) number. The ETM scheme does not require the use of characteristics at vessel junctions, or for inlet and outlet boundary conditions. The ETM forms an implicit system of equations, which requires only one global solve per time step for pressure, followed by flow rate update on the elemental system of equations; thus, no iterations are required per time step. Consistent results are found for all benchmark cases, and for a 56 vessel arterial network problem, it gives very satisfactory solutions at a spatial and time discretization that results in a maximum CFL of 3, taking 4.44 seconds per cardiac cycle. By increasing the time step and element size to produce a maximum CFL number of 15, the method takes only 0.39 second per cardiac cycle with only a small compromise on accuracy. PMID- 27709801 TI - Enzymatic Kinetic Resolution of Secondary Alcohols Using an Ionic Anhydride Generated In Situ. AB - We developed a method for the resolution of secondary alcohols using an ionic anhydride acylating agent prepared directly in the reaction medium containing the biocatalyst Candida antarctica lipase B (CALB). NMR studies showed that mixing all components at the same time does not interfere with the coupling reaction or the enzymatic activity. After optimization of the reaction conditions, the method allowed the resolution of a number of substrates in very high conversions (46-48 %) and enantiomeric ratios (E>170) along with an easy recovery of both enantiomers without the need for preparative chromatographic separation. Additionally, both the starting ionic acid and the biocatalyst could be recovered and reused up to nine cycles without significant loss of enantioselectivity. PMID- 27709799 TI - Neurotrophic Factor-alpha1: A Key Wnt-beta-Catenin Dependent Anti-Proliferation Factor and ERK-Sox9 Activated Inducer of Embryonic Neural Stem Cell Differentiation to Astrocytes in Neurodevelopment. AB - Embryonic neurodevelopment involves inhibition of proliferation of multipotent neural stem cells (NSCs) followed by differentiation into neurons, astrocytes and oligodendrocytes to form the brain. We have identified a new neurotrophic factor, NF-alpha1, which inhibits proliferation and promotes differentiation of NSC/progenitors derived from E13.5 mouse cortex. Inhibition of proliferation of these cells was mediated through negatively regulating the Wnt pathway and decreasing beta-catenin. NF-alpha1 induced differentiation of NSCs to astrocytes by enhancing Glial Fibrillary Acidic Protein (GFAP) expression through activating the ERK1/2-Sox9 signaling pathway. Cultured E13.5 cortical stem cells from NF alpha1-knockout mice showed decreased astrocyte numbers compared to wild-type mice, which was rescued by treatment with NF-alpha1. In vivo, immunocytochemistry of brain sections and Western blot analysis of neocortex of mice showed a gradual increase of NF-alpha1 expression from E14.5 to P1 and a surge of GFAP expression at P1, the time of increase in astrogenesis. Importantly, NF-alpha1-Knockout mice showed ~49% fewer GFAP positive astrocytes in the neocortex compared to WT mice at P1. Thus, NF-alpha1 is critical for regulating antiproliferation and cell fate determination, through differentiating embryonic stem cells to GFAP-positive astrocytes for normal neurodevelopment.

PMID- 27709803 TI - Inter-scan and inter-observer tumour volume delineation variability on cone beam computed tomography in patients treated with stereotactic body radiation therapy for early-stage non-small cell lung cancer. AB - INTRODUCTION: Quantification of volume changes on cone beam computed tomography (CBCT) during lung stereotactic body radiation therapy (SBRT) for non-small cell lung cancer (NSCLC) may provide a useful radiological marker for radiation response and for adaptive treatment planning. This study quantifies inter-scan and inter-observer variability in tumour volume delineation on CBCT. METHODS: Three clinicians independently contoured the primary gross tumour volume (GTV) manually on CBCTs taken immediately before SBRT treatment (pre) and after the same SBRT treatment (post) for 19 NSCLC patients. Relative volume differences (RVD) were calculated between the pre- and post-CBCTs for a given treatment and between any two of three observers for a given CBCT. Coefficient of variation (CV) was used to quantitatively measure and compare the extent of variability. RESULTS: Inter-observer variability had a significantly higher CV of 0.15 +/- 0.13 compared to inter-scan CV of 0.03 +/- 0.04 with P < 0.0001. The greatest variability was observed with tumours (<2 cm in diameter) versus larger tumours with 95% limit of agreement (LOA) (Mean +/- Standard Deviation) of 1.90% +/- 19.55% vs. -0.97% +/- 12.26% for inter-scan RVD and 29.99% +/- 73.84% vs. 9.37% +/- 29.95% for inter-observer RVD respectively. CONCLUSIONS: Inter-observer variability was greater than inter-scan variability for tumour volume delineation on CBCT with greatest variability for small tumours (<2 cm in diameter).

AB - The CYP21A2 mutations that are in linkage disequilibrium with particular HLA-A, B, -DRB1 alleles/haplotypes, cause deficiency of the 21-hydroxylase enzyme (21 OHD) and account for the majority of congenital adrenal hyperplasia (CAH) cases. The aim of this study was to investigate those associations with the p.V282L mutation linked to the non-classical (NC) form of CAH among Croatians. The study included parents of patients with the NC form of CAH, positive for the p.V282L mutation (N = 55) and cadaveric donor samples (N = 231). All subjects were HLA-A, -B, and -DRB1 typed and tested for the presence of the p.V282L mutation. Among parents of patients, 92.73% of subjects were positive for the B*14:02 allele and almost half of them carried the HLA-A*33:01-B*14:02-DRB1*01:02 haplotype. Among cadaveric samples 77 out of 96 subjects positive for the B*14:02 allele had the p.V282L mutation. Among them, 37 were positive for the HLA-A*33:01-B*14:02 DRB1*01:02 haplotype, 23 had the HLA-A*33:01-B*14:02-DRB1*03:01 haplotype, 8 had the B*14:02-DRB1*01:02 combination and 5 were carrying the HLA-A*68:02-B*14:02 DRB1*13:03 haplotype. Only 4 of these subjects were positive for the B*14:02 allele. HLA-B*14:02 was the only single allele with association that reached statistically significant P value (RR = 12.00; P = 0.0024). Haplotypes B*14:02 DRB1*01:02 (P < 0.001) and HLA-A*68:02-B*14:02-DRB1*13:03 (P < 0.001) as well as HLA-A*33:01-B*14:02-DRB1*01:02 and HLA-A*33:01-B*14:02-DRB1*03:01 showed high relative risks (RR = 45.00, RR = 41.63 and RR = 36.96, respectively). Our data support the previously documented association of the HLA-A*33:01-B*14:02 DRB1*01:02 haplotype with the p.V282L mutation, but also point out a high frequency of the p.V282L mutation among Croatians with HLA-A*33:01-B*14:02 DRB1*03:01 and HLA-A*68:02-B*14:02-DRB1*13:03 haplotypes.

High-throughput sequencing (HTS) technologies have been widely applied to the study of food microbial consortia and the different applications of HTS technologies were exploited in order to monitor microbial dynamics in food fermentative processes. Phylobiomics was the most explored application in the past decade. Metagenomics and metatranscriptomics, although still underexploited, promise to uncover the functionality of complex microbial consortia. The new knowledge acquired will help to understand how to make a profitable use of microbial genetic resources and modulate key activities of beneficial microbes in order to ensure process efficiency, product quality and safety. PMID- 27709804 TI - Impaired hepato-renal function defined by the MELD XI score as prognosticator in acute heart failure. AB - AIM: Multi-organ dysfunction often complicates the natural course of acute heart failure (AHF) and identifies patients with poor prognosis. The MELD score (Model of End-Stage Liver Dysfunction) combines data reflecting liver and kidney function, which makes it a potentially useful tool for the assessment of patients with AHF. The aim of this study was to assess the prognostic utility of the MELD score in patients with AHF. METHODS AND RESULTS: The MELD score was calculated on admission and during hospital stay (days 2-3) using a formula that does not take into account the international normalized ratio (MELD XI). The study population consisted of 203 AHF patients (mean age 65 +/- 12 years, 76% male). The mean MELD XI score was -14.8 +/- 4.5 points on admission and 13.9 +/- 4.3 points during hospitalization. Contributors of elevated MELD XI score at baseline and during hospital stay were isolated increase in creatinine in 22-25%, isolated increase in bilirubin in 17-19%, and abnormal values of both in 40-46% of patients. During 1-year follow-up, 67 (33%) patients died. After adjustment for well-established prognosticators, MELD XI score at baseline and during hospital stay were significant predictors of poor outcome [hazard ratio (95% confidence interval): 1.11 (1.05-1.2) and 1.14 (1.09-1.2), respectively, P < 0.001]. An increase in the MELD XI score during hospital stay occurred in 31% of patients and was related to increased risk of death at 1 year [1.97 (1.2-3.2), P < 0.005]. CONCLUSIONS: Impairment of hepato-renal function defined by the MELD XI score is common and carries unfavourable prognosis in AHF patients.

AB - AIMS AND OBJECTIVES: The study explored the psychosocial effects of transitioning from home to an aged care home for older Iranian people. BACKGROUND: Moving from one's own home to a communal aged care home is challenging for older people and may give rise to numerous psychosocial responses. The extent and intensity of such changes have rarely been explored in Middle Eastern countries. DESIGN: Data were collected through purposive sampling by in-depth semi-structured interviews with 20 participants (17 people living in aged care homes and three formal caregivers). All the interviews were recorded and typed, and conventional qualitative content analysis was used, eliciting common themes. RESULTS: There were four common themes: communication isolation, resource change, monotone institutional life and negative emotional response. Participants lost their previous support systems when transitioning to an aged care home and were not able to establish new ones. Routine care was provided by formal caregivers with little attention to individual needs, and minimal support was given to help maintain the older person's independence. These losses gave rise to negative emotions in some of the participants, depending on their previous lifestyle and accommodation arrangements. CONCLUSIONS: The extent and intensity of psychosocial changes occurring in most of the participants following their transition to an aged care home indicates the need for a review of Iranian aged care services. IMPLICATIONS FOR PRACTICE: To assist older Iranian people adapt more readily when making the transition to aged care home and to meet their unique psychosocial needs, a family-centred approach to service delivery is recommended.

PMID- 27709810 TI - Diagnostic performance of multi-slice CT angiography combined with enterography for small bowel obstruction and intestinal ischaemia. AB - INTRODUCTION: This study was performed to evaluate the diagnostic performance of multi-slice CT angiography combined with enterography in determining the cause and location of obstruction as well as intestinal ischaemia in patients with small bowel obstruction (SBO). METHODS: This study retrospectively summarized the image data of 57 SBO patients who received both multi-slice CT angiography and enterography examination between December 2012 and May 2013. The CT diagnoses of SBO and intestinal ischaemia were correlated with the findings at surgery or digital subtraction angiography, which were set as standard references. RESULTS: Multi-slice CT angiography and enterography indicated that the cause of SBO in three patients was misjudged, suggesting a diagnostic accuracy of 94.7%. In one patient the level of obstruction was incorrect, demonstrating a diagnostic accuracy of 98.2%. Based on the results of the receiver operating characteristic (ROC) curve analysis, the diagnostic criterion for ischaemic SBO was at least two of the four CT signs (circumferential bowel wall thickening, reduced enhancement of the intestinal wall, mesenteric oedema and mesenteric vascular engorgement). The criterion yielded a sensitivity of 94.4%, a specificity of 92.3%, a positive predicted value of 85.0% and a negative predicted value of 97.3%, and the area under curve (AUC) was 0.92 (95% CI, 0.85-0.99). CONCLUSION: Multi-slice CT angiography and enterography have high diagnostic value in identifying the cause and site of SBO. In addition, the suggested diagnostic criterion using CT signs is helpful for diagnosing intestinal ischaemia in SBO patients.

The use of magnetic resonance imaging (MRI) for male breast cancer is not generally indicated. We present an unusual case where conventional imaging for a suspected MBC was equivocal and MRI was required to assist in diagnosis. PMID- 27709812 TI - A novel filtration system for point of care washing of cellular therapy products. AB - The cell therapy industry would greatly benefit from a simple point of care solution to remove dimethylsulphoxide (DMSO) from small-volume thawed cell suspensions before injection. A novel dead-end filtration device has been designed and validated, which takes advantage of the higher density of thawed cell suspensions to remove the DMSO and protein impurities from the cell suspension without fouling the filter membrane. The filter was designed to avoid fluid circuits and minimize the surface area that is contacted by the cell suspension, thus reducing cell losses by design. The filtration process was established through optimization of the fluid flow configuration, backflush cycles and filter geometry. Overall, this novel filtration device allows for a 1 ml of thawed cryopreserved cell suspensions, containing 107 cells of a fetal lung fibroblast cell line (MRC-5), to be washed in less than 30 min. More than 95% of the DMSO and up to 94% of the albumin-fluorescein-isothiocyanate content can be removed while the viable cell recovery is higher than 80%. It is also demonstrated that this system can be used for bone marrow-derived human mesenchymal stem cells with more than 73% cell recovery and 85% DMSO reduction. This is the first time that a dead end (normal) filtration process has been used to successfully wash high-density human cell suspensions. In practice, this novel solid-liquid separation technology fills the need for small-volume washing in closed processing systems for cellular therapies. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27709815 TI - Bismuth Complexes in Phenylazomethine Dendrimers: Controllable Luminescence and Emission in the Solid State. AB - Dendritic phosphors were obtained by the stepwise integration of BiCl3 in phenylazomethine dendrimers. The bismuth-coordinated phenylazomethines displayed photoluminescence at 500-800 nm, and the intensity could be tuned by changing the stoichiometry of BiCl3 and the dendrimer. This phosphor did not show serious luminescence quenching even though the local concentration of BiCl3 in the dendrimer was as high as 20 M, and luminescence was also observed in the solid state. The absorption and emission properties could be reversibly switched by addition of a Lewis base or under electrochemical redox control, which induced the reversible complexation of BiCl3 in the dendrimer. PMID- 27709814 TI - Determination of differentially regulated proteins upon proteasome inhibition in AML cell lines by the combination of large-scale and targeted quantitative proteomics. AB - The ubiquitin-proteasome pathway (UPP) plays a critical role in the degradation of proteins implicated in cell cycle control, signal transduction, DNA damage response, apoptosis and immune response. Proteasome inhibitors can inhibit the growth of a broad spectrum of human cancer cells by altering the balance of intracellular proteins. However, the targets of these compounds in acute myeloid leukemia (AML) cells have not been fully characterized. Herein, we combined large scale quantitative analysis by SILAC-MS and targeted quantitative proteomic analysis in order to identify proteins regulated upon proteasome inhibition in two AML cell lines displaying different stages of maturation: immature KG1a cells and mature U937 cells. In-depth data analysis enabled accurate quantification of more than 7000 proteins in these two cell lines. Several candidates were validated by selected reaction monitoring (SRM) measurements in a large number of samples. Despite the broad range of proteins known to be affected by proteasome inhibition, such as heat shock (HSP) and cell cycle proteins, our analysis identified new differentially regulated proteins, including IL-32, MORF family mortality factors and apoptosis inducing factor SIVA, a target of p53. It could explain why proteasome inhibitors induce stronger apoptotic responses in immature AML cells.

AB - A tandem allene aziridination/[4+3]/reduction sequence converts simple homoallenic sulfamates into densely functionalized aminated cycloheptenes, where the relative stereochemistry at five contiguous asymmetric centers can be controlled through the choice of the solvent and the reductant. The products resulting from this chemistry can be readily transformed into complex molecular scaffolds which contain up to seven contiguous stereocenters. PMID- 27709817 TI - Tunable Probes with Direct Fluorescence Signals for the Constitutive and Immunoproteasome. AB - Electrophiles are commonly used for the inhibition of proteases. Notably, inhibitors of the proteasome, a central determinant of cellular survival and a target of several FDA-approved drugs, are mainly characterized by the reactivity of their electrophilic head groups. We aimed to tune the inhibitory strength of peptidic sulfonate esters by varying the leaving groups. Indeed, proteasome inhibition correlated well with the pKa of the leaving group. The use of fluorophores as leaving groups enabled us to design probes that release a stoichiometric fluorescence signal upon reaction, thereby directly linking proteasome inactivation to the readout. This principle could be applicable to other sulfonyl fluoride based inhibitors and allows the design of sensitive probes for enzymatic studies. PMID- 27709813 TI - Expression of Tim-1 in primary CNS lymphoma. AB - Primary central nervous system lymphoma (PCNSL) is a distinct subtype of extranodal lymphoma with aggressive clinical course and poor outcome. As increased IL-10/IL-6 ratio is recognized in the cerebrospinal fluid (CSF) of PCNSL patients, we hypothesized that PCNSL might originate from a population of B cells with high IL-10-producing capacity, an equivalent of "regulatory B cells" in mice. We intended in this study to clarify whether Tim-1, a molecule known as a marker for regulatory B cells in mice, is expressed in PCNSL. By immunohistochemical analysis, Tim-1 was shown to be positive in as high as 54.2% of PCNSL (26 of 58 samples), while it was positive in 19.1% of systemic diffuse large B-cell lymphoma (DLBCL) samples (17 of 89 samples; P < 0.001). Tim-1 expression positively correlated with IL-10 expression in PCNSL (Cramer's V = 0.55, P < 0.001), and forced expression of Tim-1 in a PCNSL cell line resulted in increased IL-10 secretion, suggesting that Tim-1 is functionally linked with IL 10 production in PCNSL. Moreover, soluble Tim-1 was detectable in the CSF of PCNSL patients, and was suggested to parallel disease activity. In summary, PCNSL is characterized by frequent Tim-1 expression, and its soluble form in CSF may become a useful biomarker for PCNSL. PMID- 27709819 TI - Isotopologous Organotellurium Probes Reveal Dynamic Hypoxia In Vivo with Cellular Resolution. AB - Changes in the oxygenation state of microenvironments within solid tumors are associated with the development of aggressive cancer phenotypes. Factors that influence cellular hypoxia have been characterized; however, methods for measuring the dynamics of oxygenation at a cellular level in vivo have been elusive. We report a series of tellurium-containing isotopologous probes for cellular hypoxia compatible with mass cytometry (MC)-technology that allows for highly parametric interrogation of single cells based on atomic mass spectrometry. Sequential labeling with the isotopologous probes (SLIP) in pancreatic tumor xenograft models revealed changes in cellular oxygenation over time which correlated with the distance from vasculature, the proliferation of cell populations, and proximity to necrosis. SLIP allows for capture of spatial and temporal dynamics in vivo using enzyme activated probes.

AB - A catalytic strategy was developed for asymmetric substitution reactions at sp3 hybridized carbon atoms by using a chiral alkylating agent generated in situ from trichloroacetimidate and a chiral phosphoric acid. The resulting chiral p methoxybenzyl phosphate selectively reacts with beta-amino alcohols rather than those without a beta-NH functionality. The use of an electronically and sterically tuned chiral phosphoric acid enables the kinetic resolution of amino alcohols through p-methoxybenzylation with good enantioselectivity.

A variety of functional groups were tolerated under the weak basic reaction conditions and at room temperature. A one-pot process was also developed to make the reaction even more practical. This method provides alternative access to oxindoles and their biologically active derivatives. PMID- 27709824 TI - Form of delivery as a key 'active ingredient' in behaviour change interventions. PMID- 27709825 TI - Comparative analysis of the main bioactive components of Xin-Sheng-Hua granule and its single herbs by ultrahigh performance liquid chromatography with tandem mass spectrometry. AB - Xin-Sheng-Hua granule, a representative formula for postpartum hemorrhage, has been used clinically to treat postpartum diseases. Its main bioactive components comprise aromatic acids, phthalides, alkaloids, flavonoids, and gingerols among others. To investigate the changes in main bioactive constituents in its seven single herbs before and after compatibility, a rapid, simple, and sensitive method was developed for comparative analysis of 27 main bioactive components by using ultrahigh-performance liquid chromatography with triple quadrupole electrospray tandem mass spectrometry for the first time. The sufficient separation of 27 target constituents was achieved on a Thermo Scientific Hypersil GOLD column (100 mm * 3 mm, 1.9 MUm) within 20 min under the optimized chromatographic conditions. Compared with the theoretical content, the observed content of each analyte showed remarkable differences in Xin-Sheng-Hua granule except thymine, p-coumaric acid, senkyunolide I, senkyunolide H, and ligustilide; the total contents of 27 components increased significantly, and the content variation degrees for the different components were gingerols > flavonoids > aromatic acids > alkaloids > phthalides. The results could provide a good reference for the quality control of Xin-Sheng-Hua granule and might be helpful to interpret the drug interactions based on variation of bioactive components in formulae. PMID- 27709826 TI - Buckwheat bioactive compounds, their derived phenolic metabolites and their health benefits. AB - SCOPE: Buckwheat (BW) consumption has been associated with a broad range of health benefits: antioxidant, anti-inflammatory and anticancer. These beneficial effects have been partially related to the presence of flavonoids. However, some of these compounds (i.e., rutin and quercetin) are metabolized in the gastrointestinal tract generating derived phenolic metabolites. In this study, we investigated the biological activity of rutin (Ru), quercetin (Q) an their derived phenolic metabolites 3,4-dihydroxyphenylacetic acid (3,4-DHPAA), 3 hydroxyphenylacetic acid (3-HPAA), and 4-hydroxy-3-methoxyphenylacetic acid (homovanillic acid, HVA). METHODS AND RESULTS: Q showed the highest antioxidant and reducing activity, and Ru the maximum chelating activity (85.33%). Antioxidant activity of 3,4-DHPAA was 5-fold higher than that of HVA, whereas their reducing activity was similar. The formation of methylglyoxal (MGO)-BSA and glucose-BSA (advanced glycation end products) was inhibited by Ru (98.5 and 92.7%), Q (95.6 and 89.1%) and 3,4-DHPPA (84.4.6 and 77.5%). Furthermore, Q (10 50 MUM) and Ru (1-50 MUM) downregulated the release of PGE2 , IL-8 and MCP-1, molecules involved in the inflammatory response, in IL1beta-inflamed myofibroblasts of colon CCD-18Co. CONCLUSION: This study suggests that BW phytochemicals and their phenolic metabolites may be responsible for the beneficial effects against chronic diseases attributed to BW consumption.

PMID- 27709828 TI - Understanding the role of new systemic agents in the treatment of prostate cancer. AB - OBJECTIVES: To examine the current literature and identify key consensus findings from the available studies to better educate urologists and medical oncologists on agents used in the treatment of metastatic prostate cancer (mPC). METHODS: Following PRISMA guidelines, we conducted a systematic review of the available literature on reported trials of systemic therapies for mPC. Two search terms were used: 'metastatic prostate cancer' and 'treatment'. RESULTS: A variety of agents have demonstrated improved overall survival in patients with mPC. Twenty recently documented trials were reported in the literature with a focus on enzalutamide, abiraterone acetate, docetaxel and other newer agents. These studies were grouped based on patient populations. CONCLUSION: The increasing number of high-quality clinical trials, with overlapping patient populations has made defining the correct therapy for men with mPC challenging for urologists and medical oncologists. The data suggests that the optimal sequence of drugs is not only unknown but also not necessarily the same for each patient. As such, we suggest a more individualized approach to the treatment of prostate cancer depending on patient and disease factors. PMID- 27709829 TI - Coronary artery calcification in Korean patients with incident dialysis. AB - INTRODUCTION: Patients with chronic kidney disease have an extremely high risk of developing cardiovascular disease (CVD). In patients with end-stage renal disease (ESRD), coronary artery calcification (CAC) is associated with increased mortality from CVD. METHODS: The present study aimed to investigate the risk factors for CAC in Korean patients with incident dialysis. Data on 423 patients with ESRD who started dialysis therapy between December 2012 and March 2014 were obtained from 10 university-affiliated hospitals. CAC was identified by using noncontrast-enhanced cardiac multidetector computed tomography. The CAC score was calculated according to the Agatston score, with CAC-positive subjects defined by an Agatston score >0. FINDINGS: Patients' mean age was 55.6 +/- 14.6 years, and 64.1% were men. The CAC-positive rate was 63.8% (270 of 423). Results of univariate analyses showed significant differences in age, sex, etiology of ESRD and comorbid conditions according to the CAC score. However, results of multiple regression analysis showed that only a higher age was significantly associated with the CAC score. Receiver operating characteristic curves showed that the sensitivity and specificity of L-spine radiography for diagnosing CAC were 56% and 91%, respectively, for diagnosing CAC (area under the curve, 0.735). DISCUSSION: CAC was frequent in patients with incident dialysis, and multiple regression analysis showed that only age was significantly associated with the CAC score. In addition, L-spine radiography could be a helpful modality for diagnosing CAC in patients with incident dialysis. PMID- 27709830 TI - A Truncated IL-17RC Peptide Ameliorates Synovitis and Bone Destruction of Arthritic Mice. AB - Peptide-based therapy, such as modified peptides, has attracted increased attention. IL-17 is a promising therapeutic target for autoimmune diseases, and levels of circulating bioactive IL-17 are associated with rheumatoid arthritis severity. In this study, a modified truncated IL-17RC is generated to ameliorate inflammation and bone destruction in arthritis. The truncated IL-17RC binds to both IL-17A and IL-17F with higher binding capacity compared to nonmodified IL 17RC. In addition, the truncated IL-17RC reduces the secretion of inflammatory and osteoclastogenic factors induced by IL-17A/F in vitro. Moreover, the administration of truncated IL-17RC dramatically improves symptoms of inflammation and inhibited bone destruction in collagen-induced arthritis mice. Collectively, these data demonstrate that modified truncated IL-17RC peptide may be a more effective treatment strategy in the simultaneous inhibition of both IL 17A and IL-17F signaling, whereas the existing agents neutralize IL-17A or IL-17F alone. These suggest that the truncated IL-17RC may be a potential candidate in the treatment of inflammatory associated bone diseases. PMID- 27709831 TI - GATA binding protein 3 is correlated with leptin regulation of PPARgamma1 in hepatic stellate cells. AB - Accumulating evidence reveals that hormone leptin, mainly produced by adipocyte, plays a unique role in promotion of liver fibrosis. Hepatic stellate cell (HSC) activation is a key step in liver fibrosis and peroxisome-proliferator activated receptor gamma (PPARgamma) exerts a crucial role in inhibition of HSC activation. Our previous researches demonstrated that leptin reduced PPARgamma1 (a major subtype of PPARgamma in HSCs) expression through GATA binding protein 2 (GATA2) binding to a site around -2323 in PPARgamma1 promoter. The present researches aimed to examine the effect of GATA3 on leptin-induced inhibition of PPARgamma1 and elucidate the relationship between GATA3 and GATA2. Gene expressions were analysed by real-time PCR, western blot, luciferase assay and immunostaining. C57BL/6J ob/ob mouse model of thioacetamide-induced liver injury was used in vivo. Results demonstrate that leptin significantly induces GATA3 expression in HSCs by multiple signalling pathways including NADPH oxidase pathway. There exist crosstalks between NADPH oxidase pathway and the other pathways. GATA3 can bind to GATA2-binding site in PPARgamma1 promoter and interacts with GATA2, contributing to leptin inhibition of PPARgamma1 expression in HSCs. These data demonstrated novel molecular events for leptin inhibition of PPARgamma1 expression in HSCs and thus might have potential implications for clarifying the detailed mechanisms underlying liver fibrosis in diseases in which circulating leptin levels are elevated such as non-alcoholic steatohepatitis in obese patients.

AB - As an Extracellular Matrix (ECM) component, Hyaluronic acid (HA) plays a multi faceted role in cell migration, proliferation and differentiation at micro level and system level events such as tissue water homeostasis. Among its biological functions, it is known to interact with cytokines and contribute to their retention in ECM microenvironment. In addition to its biological functions, it has advantageous physical properties which result in the industrial endeavors in the synthesis and extraction of HA for variety of applications ranging from medical to cosmetic. Recently, HA and its derivatives have been the focus of active research for applications in biomedical device coatings, drug delivery systems and in the form of scaffolds or cell-laden hydrogels for tissue engineering. A specific reason for the increase in use of HA based structures is their immunomodulatory and regeneration inducing capacities. In this context, this article reviews recent literature on modulation of the implantable biomaterial microenvironment by systems based on HA and its derivatives, particularly hydrogels and microscale coatings that are able to deliver cytokines in order to reduce the adverse immune reactions and promote tissue healing. PMID- 27709833 TI - Mechanism-Guided Design and Synthesis of a Mitochondria-Targeting Artemisinin Analogue with Enhanced Anticancer Activity. AB - Understanding the mechanism of action (MOA) of bioactive natural products will guide endeavor to improve their cellular activities. Artemisinin and its derivatives inhibit cancer cell proliferation, yet with much lower efficiencies than their roles in killing malaria parasites. To improve their efficacies on cancer cells, we studied the MOA of artemisinin using chemical proteomics and found that free heme could directly activate artemisinin. We then designed and synthesized a derivative, ART-TPP, which is capable of targeting the drug to mitochondria where free heme is synthesized. Remarkably, ART-TPP exerted more potent inhibition than its parent compound to cancer cells. A clickable probe ART TPP-Alk was also employed to confirm that the attachment of the TPP group could label more mitochondrial proteins than that for the ART derivative without TPP (AP1). This work shows the importance of MOA study, which enables us to optimize the design of natural drug analogues to improve their biological activities. PMID- 27709834 TI - 'Compromise position' image alignment to accommodate independent motion of multiple clinical target volumes during radiotherapy: A high risk prostate cancer example. AB - INTRODUCTION: Inclusion of multiple independently moving clinical target volumes (CTVs) in the irradiated volume causes an image guidance conundrum. The purpose of this research was to use high risk prostate cancer as a clinical example to evaluate a 'compromise' image alignment strategy. METHODS: The daily pre treatment orthogonal EPI for 14 consecutive patients were included in this analysis. Image matching was performed by aligning to the prostate only, the bony pelvis only and using the 'compromise' strategy. Residual CTV surrogate displacements were quantified for each of the alignment strategies. RESULTS: Analysis of the 388 daily fractions indicated surrogate displacements were well correlated in all directions (r2 = 0.95 (LR), 0.67 (AP) and 0.59 (SI). Differences between the surrogates displacements (95% range) were -0.4 to 1.8 mm (LR), -1.2 to 5.2 mm (SI) and -1.2 to 5.2 mm (AP). The distribution of the residual displacements was significantly smaller using the 'compromise' strategy, compared to the other strategies (p 0.005). The 'compromise' strategy ensured the CTV was encompassed by the PTV in all fractions, compared to 47 PTV violations when aligned to prostate only. CONCLUSIONS: This study demonstrated the feasibility of a compromise position image guidance strategy to accommodate simultaneous displacements of two independently moving CTVs. Application of this strategy was facilitated by correlation between the CTV displacements and resulted in no geometric excursions of the CTVs beyond standard sized PTVs. This simple image guidance strategy may also be applicable to other disease sites that concurrently irradiate multiple CTVs, such as head and neck, lung and cervix cancer. PMID- 27709835 TI - Photochemical Molecular Tailoring for Efficient Diffusion and Reorganization of Organic Nanocrystals for Ultra-Flexible Organic Semiconductor Arrays. AB - Solution-processed organic single crystals with high carrier mobility have been actively investigated for diverse applications such as displays, sensors, and next generation electronics on a flexible platform. However, the lack of precise alignment and growth control of organic single crystals impedes the widespread adoption of organic materials in an industrial perspective. Here, a photochemical modification approach is reported tailoring the solubility and molecular diffusivity of polymeric sacrificial layer and sequential batch-type vapor annealing to implement high-performance (average saturation mobility: 8.01 cm2 V 1 s-1 ) organic single-crystal thin film transistors with large channel width including multiple aligned single crystals. Additionally, the mechanical properties of the organic single crystals are systematically investigated with extreme strain conditions such as bending radius of 150 MUm.

AB - A rapid and sensitive method for the extraction and determination of four major polyphenolic components in Euphoria longana Lam. seeds is presented for the first time based on matrix solid-phase dispersion extraction followed by ultra high performance liquid chromatography with hybrid triple quadrupole linear ion trap mass spectrometry. Matrix solid-phase dispersion method was designed for the extraction of Euphoria longana seed constituents and compared with microwave assisted extraction and ultrasonic-assisted extraction methods. An Ultra high performance liquid chromatography with hybrid triple quadrupole linear ion-trap mass spectrometry method was developed for quantitative analysis in multiple reaction monitoring mode in negative electrospray ionization. The chromatographic separation was accomplished using an ACQUITY UPLC BEH C18 (2.1 mm * 50 mm, 1.7 MUm) column with gradient elution of 0.1% aqueous formic acid and 0.1% formic acid in acetonitrile. The developed method was validated with acceptable linearity (r2 > 0.999), precision (RSD <= 2.22%) and recovery (RSD <= 2.35%). The results indicated that matrix solid-phase dispersion produced comparable extraction efficiency compared with other methods nevertheless was more convenient and time-saving with reduced requirements on sample and solvent volumes. The proposed method is rapid and sensitive in providing a promising alternative for extraction and comprehensive determination of active components for quality control of Euphoria longana products. PMID- 27709837 TI - Development of CAPTSureTM - a new index for the assessment of pediatric postthrombotic syndrome. AB - : Essentials We developed a discriminative and evaluative index for pediatric postthrombotic syndrome (PTS). A Delphi-survey was used for item reduction and multi-criteria decision analysis for item weighting. The new index assesses limb PTS based on the relative severity of each sign and symptom. Higher scores related to higher odds of parental dissatisfaction with their child's condition. SUMMARY: Background Postthrombotic syndrome (PTS) is a complication of deep vein thrombosis defined by the presence of characteristic signs and symptoms. We developed a discriminative and evaluative index for the assessment of upper extremity (UE) and lower extremity (LE) pediatric PTS. Methods The items to be included in the index were voted for by 26 pediatric thrombosis experts invited to participate in a Delphi survey. Subsequent item weighting was based on item importance elicited by the use of multicriteria decision analysis (MCDA); 122 healthcare providers and patients/parents were invited to participate in item weighting. The implications of the overall scores were explored by comparison with PTS diagnosis (independently assessed by two clinical experts) and parental satisfaction/dissatisfaction with their child's current condition. Results Items voted for inclusion by at least 70% of the Delphi survey respondents (81% response rate) were pain, paresthesia, swelling, heaviness, endurance, collateral circulation and arm circumference difference for the UE, and pain, paresthesia, swelling, heaviness, tightness, tired limb, redness/purple or blotchy skin, endurance, ulcers and thigh/calf circumference difference for the LE. Items were then weighted by the use of MCDA (82% response rate). The index had excellent discrimination for patients with/without PTS. For every 10-point increase in index scores (with higher scores being indicative of worse PTS), the odds of parental dissatisfaction increased by 75% and 92% in the UE and LE, respectively. Conclusion We report the development of the CAPTSureTM (index for the Clinical Assessment of Postthrombotic Syndrome in children), which reflects collective judgement of the severity of pediatric PTS. We also provide information on the meaning of the scores. PMID- 27709840 TI - Expanded 3D Nanofiber Scaffolds: Cell Penetration, Neovascularization, and Host Response. AB - Herein, a robust method to fabricate expanded nanofiber scaffolds with controlled size and thickness using a customized mold during the modified gas-foaming process is reported. The expansion of nanofiber membranes is also simulated using a computational fluid model. Expanded nanofiber scaffolds implanted subcutaneously in rats show cellular infiltration, whereas non-expanded scaffolds only have surface cellular attachment. Compared to unexpanded nanofiber scaffolds, more CD68+ and CD163+ cells are observed within expanded scaffolds at all tested time points post-implantation. More CCR7+ cells appear within expanded scaffolds at week 8 post-implantation. In addition, new blood vessels are present within the expanded scaffolds at week 2. The formed multinucleated giant cells within expanded scaffolds are heterogeneous expressing CD68, CCR7, or CD163 markers. Together, the present study demonstrates that the expanded nanofiber scaffolds promote cellular infiltration/tissue integration, a regenerative response, and neovascularization after subcutaneous implantation in rats. The use of expanded electrospun nanofiber scaffolds offers a promising method for in situ tissue repair/regeneration and generation of 3D tissue models/constructs.

PMID- 27709838 TI - Time to follow-up of an abnormal mammogram in women with diabetes: a population based study. AB - Women with diabetes have a higher breast cancer incidence and mortality. They are also significantly less likely to undergo screening mammography and present with more advanced stage than women without diabetes. The purpose of this study was to examine if women with diabetes are more likely to have delays in follow-up of abnormal mammograms, compared to women without diabetes. Using population-based health databases, this retrospective cohort study examined women between the ages of 50 and 74, with and without diabetes, living in the province of Ontario, Canada, who underwent screening through a centralized program and who had an abnormal mammogram between 2003 and 2012. We compared rates of follow-up of a diagnostic test within 180 days, as well as likelihood of mastectomy or excision procedure and a diagnosis of breast cancer. Following an abnormal screening mammogram, 97.5% of women with diabetes had a diagnostic procedure within 180 days compared to 97.9% of women without diabetes. After adjustment for other factors, women with diabetes were only 3% less likely to have follow-up testing after an abnormal mammogram than women without diabetes (hazard ratio [HR] 0.97, 95% CI: 0.96-0.99, P < 0.001). The majority of Ontario women who underwent screening mammography through a centralized screening program had timely follow up of an abnormal mammogram, with no meaningful delays in those who had diabetes. The results of this study suggest that diagnostic delays after screening do not significantly contribute to higher breast cancer mortality in women with diabetes. PMID- 27709843 TI - The Ecology of Medical Care in Korea. AB - This study aimed to describe the ecology of medical care in Korea. Using the yearly data of 2012 derived from the Korea Health Panel, we estimated the numbers of people per 1,000 residents aged 18 and over who had any health problem and/or any medical care at a variety of care settings, such as clinics, hospitals, and tertiary hospitals, in an average month. There was a total of 11,518 persons in the study population. While the number of those who had any health problem in an average month was estimated to be 939 per 1,000 persons, the estimated numbers of ambulatory care users were 333 at clinics, 101 at hospital outpatient departments, 35 at tertiary hospital outpatient departments, and 38 for Korean Oriental medical providers. The number of people who used emergency care at least once was 7 per 1,000 persons in an average month. The numbers of people hospitalized in clinics and hospitals were 3 and 8, respectively, while 3 persons were admitted to tertiary hospitals. There was a gap between the number of people experiencing any health problem and that of those having any medical care, and primary care comprised a large share of people's medical care experiences. It was noteworthy that more patients received ambulatory care at tertiary hospitals in Korea than in other countries. We hope that discussion about care delivery system reform and further studies will be encouraged. PMID- 27709842 TI - Molecular Strain Typing of Mycobacterium tuberculosis: a Review of Frequently Used Methods. AB - Tuberculosis, caused by the bacterium Mycobacterium tuberculosis, remains one of the most serious global health problems. Molecular typing of M. tuberculosis has been used for various epidemiologic purposes as well as for clinical management. Currently, many techniques are available to type M. tuberculosis. Choosing the most appropriate technique in accordance with the existing laboratory conditions and the specific features of the geographic region is important. Insertion sequence IS6110-based restriction fragment length polymorphism (RFLP) analysis is considered the gold standard for the molecular epidemiologic investigations of tuberculosis. However, other polymerase chain reaction-based methods such as spacer oligonucleotide typing (spoligotyping), which detects 43 spacer sequence interspersing direct repeats (DRs) in the genomic DR region; mycobacterial interspersed repetitive units-variable number tandem repeats, (MIRU-VNTR), which determines the number and size of tandem repetitive DNA sequences; repetitive sequence-based PCR (rep-PCR), which provides high-throughput genotypic fingerprinting of multiple Mycobacterium species; and the recently developed genome-based whole genome sequencing methods demonstrate similar discriminatory power and greater convenience. This review focuses on techniques frequently used for the molecular typing of M. tuberculosis and discusses their general aspects and applications. PMID- 27709845 TI - Facing Complaining Customer and Suppressed Emotion at Worksite Related to Sleep Disturbance in Korea. AB - This study aimed to investigate the effect of facing complaining customer and suppressed emotion at worksite on sleep disturbance among working population. We enrolled 13,066 paid workers (male = 6,839, female = 6,227, age < 65 years) in the 3rd Korean Working Condition Survey (2011). The odds ratio (OR) and 95% confidence intervals (CI) for sleep disturbance occurrence were calculated using multiple logistic regression models. Among workers in working environments where they always engage complaining customers had a significantly higher risk for sleep disturbance than rarely group (The OR [95% CI]; 5.46 [3.43-8.68] in male, 5.59 [3.30-9.46] in female workers). The OR (95% CI) for sleep disturbance was 1.78 (1.16-2.73) and 1.63 (1.02-2.63), for the male and female groups always suppressing their emotions at the workplace compared with those rarely group. Compared to those who both rarely engaged complaining customers and rarely suppressed their emotions at work, the OR (CI) for sleep disturbance was 9.66 (4.34-20.80) and 10.17 (4.46-22.07), for men and women always exposed to both factors. Sleep disturbance was affected by interactions of both emotional demands (engaging complaining customers and suppressing emotions at the workplace). The level of emotional demand, including engaging complaining customers and suppressing emotions at the workplace is significantly associated with sleep disturbance among Korean working population. PMID- 27709844 TI - Gender Differences in Sleep Disturbance among Elderly Koreans: Hallym Aging Study. AB - Sleep is an important component in our lives as it is necessary throughout one's entire life span. This study was conducted to elucidate whether there are gender differences in sleep quality and what factors can affect sleep quality in community-dwelling elderly Koreans. A total of 382 subjects (175 males and 207 females) were recruited among elderly aged 45 or over who participated in the 2010 Hallym Aging Study (HAS). They were invited to a general hospital and were evaluated for socioeconomic status, smoking history, and various clinical measures. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). A higher score indicates poorer subjective sleep quality, (PSQI global score > 5 suggests sleep disturbance). After adjusting for potential covariates, our results show that alcohol increases the odds for poor sleep (odds ratio [OR] = 3.35, 95% confidence interval [CI] = 1.11-10.10) in males. In females, lack of exercise was the major risk factor of poor sleep as they are 4.46 times more likely to suffer from low sleep quality than those who exercise regularly (95% CI=1.56-13.75). Stress was also a risk factor for poor sleep. It was 5.60 times higher in the "always have stress" group than the "do not have stress" group (95% CI = 1.54-20.34). Thus, alcohol consumption is associated with men's sleep quality, while exercise and stress level affect women's. PMID- 27709846 TI - Public Awareness of Stroke and Its Predicting Factors in Korea: a National Public Telephone Survey, 2012 and 2014. AB - The aim of this study was to investigate time trends in the public awareness of stroke and its predicting factors. The target population was 9,600 community dwelling adults, aged 19-79 years, in 16 metropolitan cities and provinces in Korea. The survey samples in 2012 and 2014 were selected separately (entirely different sets of subjects) using a proportionate quota sampling method. Information concerning knowledge of stroke and demographics was collected by trained telephone interviewers using random digit dialing. After excluding subjects with a non-response or refusal to answer any question, the analyses included 8,191 subjects in 2012 and 8,127 subjects in 2014. Respondents' awareness of stroke warning signs (numbness or weakness, difficulty speaking or understanding speech, dizziness, visual impairment, and severe headache) was highest for difficulty speaking or understanding speech (80.9% in 2012 and 86.4% in 2014). There were significant increases in the proportion of respondents understanding the appropriate action (i.e., calling an ambulance) at the time of stroke occurrence (59.6% to 67.1%), and in the proportion aware of the general need for prompt treatment (86.7% to 89.8%). In multivariable logistic regression analysis, older age, higher education level, higher household income, current non smoking, exposure to stroke-related public relations materials, and experience of stroke education were significantly associated with both high knowledge of stroke warning signs and awareness of the need for prompt treatment. Between 2012 and 2014, the public's awareness of stroke increased significantly. More specialized interventions, including public relations materials and education, should focus on subgroups who have lower stroke knowledge. PMID- 27709847 TI - Risk Factors for the Adverse Events after Conversion from Twice-Daily to Once Daily Tacrolimus in Stable Liver Transplantation Patients. AB - Despite the therapeutic equivalence between twice-daily and once-daily tacrolimus, patient safety after conversion is still a concern. We reviewed 218 liver transplantation (LT) patients who converted twice-daily to once-daily tacrolimus between May 2011 and January 2014. Thirty (13.8%) patients had adverse events after conversion, with a liver function test (LFT) abnormality being the most common adverse event (n = 17). Despite the decrease in serum tacrolimus of > 30% after conversion, none of the patients who were converted to a dosage ratio (once-daily tacrolimus dosage: twice-daily tacrolimus dosage) > 1 had an LFT abnormality. Most patients with an LFT abnormality improved after increasing the once-daily tacrolimus dosage (n = 2), returned to a previous medication, and/or added another immunosuppressant (n = 15). One patient had acute cellular rejection, which improved after steroid pulse treatment, and another patient had graft failure. In patients with a dosage ratio <= 1, the conversion time within 5 years after LT was the only significant risk factor for an LFT abnormality after conversion (odds ratio: 11.850, 95% confidence interval: 1.321-106.325, P = 0.027). In conclusion, the dosage ratio and time after LT should be carefully considered during conversion from twice-daily to once-daily tacrolimus. PMID- 27709848 TI - Clinical Progression and Cytokine Profiles of Middle East Respiratory Syndrome Coronavirus Infection. AB - Clinical progression over time and cytokine profiles have not been well defined in patients with Middle East respiratory syndrome coronavirus (MERS-CoV) infection. We included 17 patients with laboratory-confirmed MERS-CoV during the 2015 outbreak in Korea. Clinical and laboratory parameters were collected prospectively. Serum cytokine and chemokine levels in serial serum samples were measured using enzyme-linked immunosorbent assay. All patients presented with fever. The median time to defervescence was 18 days. Nine patients required oxygen supplementation and classified into severe group. In the severe group, chest infiltrates suddenly began to worsen around day 7 of illness, and dyspnea developed at the end of the first week and became apparent in the second week. Median time from symptom onset to oxygen supplementation was 8 days. The severe group had higher neutrophil counts during week 1 than the mild group (4,500 vs. 2,200/MUL, P = 0.026). In the second week of illness, the severe group had higher serum levels of IL-6 (54 vs. 4 pg/mL, P = 0.006) and CXCL-10 (2,642 vs. 382 pg/mL, P < 0.001). IFN-alpha response was not observed in mild cases. Our data shows that clinical condition may suddenly deteriorate around 7 days of illness and the serum levels of IL-6 and CXCL-10 was significantly elevated in MERS-CoV patients who developed severe diseases. PMID- 27709849 TI - Neurocognitive Function and Health-Related Quality of Life in Pediatric Korean Survivors of Medulloblastoma. AB - The neurocognitive function and quality of life of 58 Korean survivors of childhood medulloblastoma were assessed after surgery, cranial radiation and chemotherapy. All patients were evaluated with a battery of neurocognitive function tests and the Pediatric Functional Assessment of Cancer Therapy-Brain Tumor Survivors, which consists of self-report questionnaires on quality of life. The mean full-scale intelligence quotient (IQ), verbal IQ, and performance IQ scores were 90.2, 97.1, and 84.16, respectively. The mean memory quotient (MQ) score was 86.78, which was within 1 standard deviation of the average score of 100. Processing speed, attention, and executive function showed mild to moderate deficits. Intelligence, memory, executive function, visuospatial function, and simple motor function were significantly lower in the patients diagnosed before 8 years of age compared with those diagnosed after 8. The cognitive deficits in the patients diagnosed at younger ages might be related to earlier exposure to craniospinal irradiation and chemotherapy. The patient and parent proxy evaluations of attention, fine motor function, and quality of life did not differ. We found significant neurocognitive changes in a wide range of neurocognitive functional domains in Korean survivors of childhood medulloblastoma. Long-term follow-up studies of survivors of childhood medulloblastoma beginning at the time of their first diagnosis are required to better understand the deficits exhibited by survivors of childhood medulloblastoma, so that intervention strategies and treatment refinements that reduce the long-term neurocognitive decline can be developed. PMID- 27709851 TI - Comparison of Dosimetric Performance among Commercial Quality Assurance Systems for Verifying Pretreatment Plans of Stereotactic Body Radiotherapy Using Flattening-Filter-Free Beams. AB - The purpose of this study was to compare the performance of different commercial quality assurance (QA) systems for the pretreatment verification plan of stereotactic body radiotherapy (SBRT) with volumetric arc therapy (VMAT) technique using a flattening-filter-free beam. The verification for 20 pretreatment cancer patients (seven lung, six spine, and seven prostate cancers) were tested using three QA systems (EBT3 film, I'mRT MatriXX array, and MapCHECK). All the SBRT-VMAT plans were optimized in the Eclipse (version 11.0.34) treatment planning system (TPS) using the Acuros XB dose calculation algorithm and were delivered to the Varian TrueBeam(r) accelerator equipped with a high-definition multileaf collimator. Gamma agreement evaluation was analyzed with the criteria of 2% dose difference and 2 mm distance to agreement (2%/2 mm) or 3%/3 mm. The highest passing rate (99.1% for 3%/3 mm) was observed on the MapCHECK system while the lowest passing rate was obtained on the film. The pretreatment verification results depend on the QA systems, treatment sites, and delivery beam energies. However, the delivery QA results for all QA systems based on the TPS calculation showed a good agreement of more than 90% for both the criteria. It is concluded that the three 2D QA systems have sufficient potential for pretreatment verification of the SBRT-VMAT plan. PMID- 27709852 TI - Natural Course of Adult Ebstein Anomaly When Treated according to Current Recommendation. AB - The objectives of this study were to assess the clinical outcomes of adults with Ebstein Anomaly (EA) according to their treatment modalities. All adult EA patients diagnosed between October 1994 and October 2014 were retrospectively evaluated by medical record review. Total 60 patients were categorized into 3 groups according to their treatment strategy, i.e. non-operative treatment (Group I, n = 23), immediate operative treatment (Group II, n = 27), and delayed operative treatment (Group III, n = 10). A composite of major adverse cardiac and cerebrovascular events (MACCE) and factors associated with MACCE were assessed in each treatment group. MACCE occurred in 13.0% patients in Group I, 55.6% patients in Group II and 50% in Group III (P = 0.006). Event free survivals at 5 years were 90% in Group I, 52.7% in Group II, 50.0% in Group III (P = 0.036). Post operatively, most patients showed improvement on clinical symptoms. However, event free survival rate was lower in patients with operation compared to those with non-operative treatment (58.7% vs. 90.9%; P = 0.007). Major arrhythmic event occurred more frequently even after surgical ablation (50.0% vs. 20.0%; P = 0.034). Re-operation was more frequent in patients underwent delayed surgery compared to those with immediate surgery (50.0% vs. 18.5%; P = 0.001). Current guideline to decide patient's treatment strategy appeared to be appropriate in adult patients with EA. However, surgical ablation for arrhythmia was not enough so that concomitant medical treatment should be considered. Therefore, attentive risk stratification and cautious decision of treatment strategy by experienced cardiac surgeon are believed to improve clinical outcome. PMID- 27709850 TI - The Different Effect of VEGF Polymorphisms on the Prognosis of Non-Small Cell Lung Cancer according to Tumor Histology. AB - Vascular endothelial growth factor (VEGF) contributes to tumor angiogenesis. The role of VEGF single nucleotide polymorphisms (SNPs) in lung cancer susceptibility and its prognosis remains inconclusive and controversial. This study was performed to investigate whether VEGF polymorphisms affect survival outcomes of patients with early stage non-small cell lung cancer (NSCLC) after surgery. Three potentially functional VEGF SNPs (rs833061T>C, rs2010963G>C, and rs3025039C>T) were genotyped. A total of 782 NSCLC patients who were treated with surgical resection were enrolled. The association of the SNPs with overall survival (OS) and disease free survival (DFS) was analyzed. In overall population, none of the three polymorphisms were significantly associated with OS or DFS. However, when the patients were stratified by tumor histology, squamous cell carcinoma (SCC) and adenocarcinoma (AC) had significantly different OS (Adjusted hazard ratio [aHR] = 0.76, 95% CI = 0.56-1.03 in SCC; aHR = 1.33, 95% CI = 0.98-1.82 in AC; P for heterogeneity = 0.01) and DFS (aHR = 0.75, 95% CI = 0.58-0.97 in SCC; aHR = 1.26, 95% CI = 1.00-1.60 in AC; P for heterogeneity = 0.004) according to the rs833061T>C genotypes. Our results suggest that the prognostic role of VEGF rs833061T>C may differ depending on tumor histology. PMID- 27709853 TI - Clinical Characteristics and Treatment Outcomes of Primary Pulmonary Artery Sarcoma in Korea. AB - Pulmonary artery sarcomas (PAS) are rare malignant neoplasms. Right heart failure due to tumour location is the main cause of death in PAS patients. The hemodynamic influence of PAS may effect prognosis, but this has not been proven. We aimed to identify the clinical characteristics and prognostic factors of PAS in Korea, their association with pulmonary hypertension (PH). PAS patients treated at the Asan Medical Center between 2000 and 2014 were reviewed. We examined demographic characteristics, diagnostic and treatment modalities. Potential prognostic factors were evaluated by univariate and multivariate analysis. Twenty patients were diagnosed with PAS. Ten patients were male, the median age was 54 years (range, 33-75 years). The most common symptom observed was dyspnea (65%). The most common histologic type was spindle cell sarcoma (30%). Ten patients had a presumptive diagnosis of pulmonary embolism (PE) and received anticoagulation therapy. Seventeen patients underwent surgery, but only 5 patients had complete resection. Eleven patients received post-operative treatment (chemotherapy = 3, radiotherapy = 5, chemoradiotherapy = 3). PH was observed in 12 patients before treatment and in 6 patients after treatment. Overall median survival was 24 months. Post-treatment PH was associated with poor prognosis (HR 9.501, 95% CI 1.79-50.32; P = 0.008) while chemotherapy was negatively associated with mortality (HR 0.102, 95% CI 0.013-0.826; P = 0.032) in univariate analysis. Post-treatment PH was also associated with poor prognosis in multivariate analysis (HR 5.7, 95% CI 1.08-30.91; P = 0.041). PAS patients are frequently misdiagnosed with PE in Korea. Post-treatment PH is associated with a poor prognosis. PMID- 27709854 TI - The Risk for Insulin Resistance according to the Degree of Non-Alcoholic Fatty Liver Disease in Korean Men. AB - Insulin resistance (IR) plays a significant role in the development and progression of non-alcoholic fatty liver disease (NAFLD). However, the natural course of insulin sensitivity under NAFLD remained unclear. Accordingly, this study was designed to investigate the effect of NAFLD on insulin resistance. A total of 20,628 Korean men without homeostasis model assessment of insulin resistance (HOMA-IR < 2.7) were followed-up for 5 years. They were serially checked for HOMA-IR to monitor the development of IR (HOMA-IR >= 2.7). The incidence rate of IR increased according to the degree of NAFLD (normal: 11.6%, mild: 28.8%, moderate to severe: 40.5%, P < 0.001). Cox proportional hazards model showed that HRs (95% CI) for IR increased proportionally to the degree of NAFLD (mild: 1.19 [1.02-1.39], moderate to severe: 1.32 [1.08-1.57]). IR was more potentially associated with the more progressive NAFLD than normal and milder state. In addition, NAFLD was the independent risk factor of the development of IR. These results suggest the potential availability of NAFLD as a predictor of IR. PMID- 27709855 TI - Using Forceps Biopsy after Small Submucosal Dissection in the Diagnosis of Gastric Subepithelial Tumors. AB - The current tissue sampling techniques for subepithelial tumors (SETs) of the gastrointestinal (GI) tract have limited diagnostic efficacy. We evaluated the diagnostic yield and safety of forceps biopsies after small endoscopic submucosal dissection (SESD biopsies) in the diagnosis of gastric SETs. A total of 42 patients with gastric SETs > 10 mm were prospectively enrolled between May 2013 and October 2014. A dual knife was used to incise the mucosa and submucosa and forceps biopsies were then introduced deep into the lesion. To compare SESD biopsies with EUS-FNA, we used the retrospective data of 30 EUS-FNA cases. The diagnostic yield of SESD biopsies was comparable to that of EUS-FNA (35/42, 83.3% vs. 24/30, 80.0%, P = 0.717). The mean procedure time of SESD biopsies was shorter than that of EUS-FNA (10 vs. 37 minutes, P < 0.001). There were no procedure-related adverse events in the both group. The pathological diagnoses in SESD biopsies group included 15 leiomyomas, 7 GISTs, 10 heterotopic pancreases, 2 lipomas, and one other lesion. SESD biopsies are an easy, effective and safe technique for the diagnosis of gastric SETs and its diagnostic yield is comparable to that of EUS-FNA. This technique may be a reliable alternative to conventional EUS-FNA (Clinical trial registration No. KCT0000730). PMID- 27709856 TI - The Experience of Human Milk Banking for 8 Years: Korean Perspective. AB - Human milk banks are a solution for mothers who cannot supply their own breast milk to their sick or hospitalized infants; premature infants, in particular, are unable to receive a full volume of breast milk for numerous reasons. As of December 2015, there was only one milk bank in a university hospital in Korea. We reviewed the basic characteristics of donors and recipients, and the amounts and contamination of breast milk donated at the Human Milk Bank in Kyung Hee University Hospital at Gangdong in Korea from 2008 to 2015. The donor pool consisted of 463 first-time donors and 452 repeat donors who made 1,724 donations. A total of 10,820 L of breast milk was collected, and 9,541.6 L were processed. Detectable bacteria grew in 12.6% after pasteurization and 52.5% had cytomegalovirus DNA before pasteurization in donated milk. There were 836 infant and 25 adult recipients; among new infant recipients, 48.5% were preterm; the groups received 8,009 and 165.7 L of donor milk, respectively. There was an increase in the percentage of preterm infants among new infant recipients in 2015 (93.1%) compared to 2008 (8.5%). Based on the number of premature infants in Korea, the number of potential recipients is not likely to diminish anytime soon, despite efforts to improve the breastfeeding rate. Sustainability and quality improvement of the milk bank need long-term financial support by health authorities and a nationwide network similar to blood banking will further contribute to the progress of milk banking. PMID- 27709857 TI - Distribution of Diseases Causing Liver Function Test Abnormality in Children and Natural Recovery Time of the Abnormal Liver Function. AB - Although liver function test abnormality is frequently noted in children, there is no report about the distribution of the etiology and natural recovery time of the abnormal liver function. From March 2005 to February 2014, clinical information was retrospectively collected from 559 children who had abnormal liver function and were hospitalized or visited the outpatient clinic at the Jeju National University Hospital. The etiology of abnormal liver function was classified into groups and the natural recovery time of abnormal liver function was analyzed. The etiological groups of 559 patients included 'nonspecific hepatitis' in 42 (7.5%), 'infection' in 323 (57.8%), 'rheumatologic and autoimmune' in 66 (11.8%), 'nonalcoholic fatty liver disease' in 57 (10.2%), 'anatomic' in 12 (2.1%), 'toxic' in 13 (2.1%), 'metabolic' in 8 (1.4%), 'hematologic' in 7 (1.3%), 'hemodynamic' in 4 (0.7%), and 'others' in 27 (4.8%). Among the 'infection' group (57.8%), the 'viral infection in the respiratory tract' subgroup, which had 111 patients (19.8%), was the most common. The natural recovery time of the abnormal liver function was 27 days (median) in 'nonspecific hepatitis', 13 days (median) in 'viral respiratory tract disease', 16 days (median) in 'viral gastroenteritis', 42 days (median) in 'viral febrile illness", and 7 days (median) in "Kawasaki disease". The information on the natural recovery time of abnormal liver function may help the physician to perform good clinical consultation for patients and their parents.

AB - Although pregnancy is a medical condition that contributes to bone loss, little information is available regarding bone mineral density (BMD) in puerperal women. This cross sectional study aimed to evaluate the prevalence of low BMD in puerperal women and to identify associated risk factors. We surveyed all puerperal women who had BMD measurements taken 4-6 weeks after delivery in a tertiary university hospital, and did not have any bone loss-related comorbidities. Among the 1,561 Korean puerperal women, 566 (36.3%) had low BMD at the lumbar spine, total hip, femoral neck, and/or trochanter. Multivariate analysis revealed that underweight women had a significantly higher risk of low BMD compared with obese women at pre-pregnancy (adjusted odds ratio [aOR], 3.21; 95% confidence interval [CI], 1.83-5.63). Also, women with inadequate gestational weight gain (GWG) were 1.4 times more likely to have low BMD than women with excessive GWG (aOR, 1.42; 95% CI, 1.04-1.94). One-way ANOVA showed that BMDs at the lumbar spine and total hip were significantly different between the 4 BMI groups (both P < 0.001) and also between the 3 GWG groups (both P < 0.001). In conclusion, this study identifies a high prevalence of low BMD in puerperal women and thus suggests the need for further evaluation about the change of BMD in pregnancy and postpartum period. PMID- 27709859 TI - Seasonal Pattern of Preterm Births in Korea for 2000-2012. AB - The aim of this study was to investigate a seasonal pattern of preterm births in Korea. Data were obtained from the national birth registry of the Korean Statistics Office and included all births in Korea during the period 2000-2012 (n = 6,310,800). Delivery dates were grouped by month of the year or by season (winter [December, January, February], spring [March, April, May], summer [June, July, August], and autumn [September, October, November]). The seasonal patterns of prevalence of preterm births were assessed. The rates of preterm births at 37 weeks were highest twice a year (once in winter and again in summer). The rates of preterm births increased by 13.9% in summer and 7.5% in winter, respectively, than in spring (OR, 1.139; 95% CI, 1.127-1.152, and OR, 1.075; 95% 1.064-1.087, respectively) after controlling for age, the educational level of the parents, maternal parity, and neonatal gender. The pattern for spontaneous preterm births < 34 weeks was similar. In Korea, a seasonal pattern of preterm births was observed, with peak prevalence in summer and winter. A seasonal pattern of preterm births may provide new insights for the pathophysiology of preterm births. PMID- 27709860 TI - Cause of Death in Korean Men with Prostate Cancer: an Analysis of Time Trends in a Nationwide Cohort. AB - Despite rapid increase in incidence of prostate cancer (PC) and PC survivors, there are few studies regarding competing causes of death and time trends in Asian population. We conducted a cohort study of 2% nationwide random sample of Korean National Health Insurance employees. A total of 873 patients who had received active treatments, including surgery, radiation therapy (RT) and androgen deprivation therapy (ADT), for newly diagnosed PC between 2003 and 2010 were included. The cause of death was categorized as PC, other cancers, cardiovascular disease, and other causes. During a median follow-up of 4.75 years, 29.4% (257/873) of the study population died. PC, other cancers, cardiovascular disease, and other causes were responsible for 46.3%, 35.4%, 6.6%, and 11.7%, respectively, of the decedents. Significant differences existed in the cause of death among treatment groups (P < 0.001). Only 20% and 9.5% of surgery and RT group died of PC, whereas 63.9% of ADT group died of PC. Other cancers were responsible for 56%, 74.6% and 17.8% of death in the surgery, RT and ADT group, respectively, while cardiovascular disease accounted for 4%, 6.3%, and 7.1% of death in the treatment groups. Analysis of time trends showed that PC specific death tended to decrease (from 42.9% in 2003 to 23.1% in 2010), whereas non-PC causes tended to increase over the 8 years. Our results are valuable in overviewing causes of death and time trends in Korean PC patients, and planning future health policy for PC. PMID- 27709861 TI - Risk Factor Analysis of Ciprofloxacin-Resistant and Extended Spectrum Beta Lactamases Pathogen-Induced Acute Bacterial Prostatitis in Korea. AB - The objectives of this study were to investigate risk factors and the incidence of ciprofloxacin resistance and extended-spectrum beta-lactamases (ESBL) in patients with acute bacterial prostatitis (ABP). We reviewed the medical records of 307 patients who were diagnosed with ABP between January 2006 and December 2015. The etiologic pathogens and risk factors for ciprofloxacin-resistant E. coli and ESBL-producing microbes, susceptibility to ciprofloxacin, and the incidence of ESBL in patients with ABP were described. History of prior urologic manipulation was an independent risk factor for ciprofloxacin-resistant (P = 0.005) and ESBL-producing microbes (P = 0.005). Advanced age (over 60 years) was an independent risk factor for ciprofloxacin-resistant microbes (P = 0.022). The ciprofloxacin susceptibility for Escherichia coli in groups without prior manipulation was documented 85.7%. For groups with prior manipulation, the susceptibility was 10.0%. Incidence of ESBL-producing microbes by pathogen was 3.8% for E. coli and 1.0% for Klebsiella pneumonia in the absence of manipulation group, and 20% and 33.3% in the presence of manipulation group, respectively. Initial treatment of ABP must consider patient's age and the possibility of prior manipulation to optimize patient treatment. With the high rate of resistance to fluoroquinolone, cephalosporins with amikacin, or carbapenems, or extended spectrum penicillin with beta lactamase inhibitor should be considered as the preferred empirical ABP treatment in the patients with history of prior urologic manipulation. PMID- 27709862 TI - Association of Overweight with the Prevalence of Lifetime Psychiatric Disorders and Suicidality: General Population-based Study in Korea. AB - Many epidemiological studies suggest that overweight is associated with an elevated risk of psychiatric disorders and suicidal tendency. However, findings vary across studies, and some have contradictory results. We investigated the relationship of overweight with a range of psychiatric disorders and suicidality in the Korean general population. A multistage cluster sampling design was adopted. A total of 6,022 participants aged 18-74 years completed face-to-face interviews (response rate: 78.7%) including assessment of psychiatric disorders, suicidality, and height and weight. Overweight (defined as body mass index of >= 25) was associated with an increase in the lifetime prevalence of depressive disorders (adjusted odds ratio [AOR] 1.38; 95% confidence interval [CI], 1.07 1.77), suicidal ideation (AOR, 1.42; 95% CI, 1.20-1.68), and suicidal plans (AOR, 1.44; 95% CI, 1.02-2.03), controlling for sociodemographic variables. Subgroup analysis found that the association between overweight and depressive disorders exists only in women aged 18-44 years (AOR, 1.75; 95% CI, 1.07-2.89) while the association of overweight with suicidal ideation (AOR, 2.08; 95% CI, 1.53-2.82) and suicide plans (AOR, 2.59; 95% CI, 1.25-5.37) existed only in men aged 18-44 years. Overweight was associated with increased odds of nicotine use disorders in women aged 18-44 years (AOR, 2.35; 95% CI, 1.02-5.43), but the association was in the opposite direction in men aged 45-74 years (AOR, 0.64; 95% CI, 0.43-0.94). In conclusion, overweight is related to various psychiatric disorders and suicidality in Korea. Policy makers and clinicians should pay more attention to the mental health of overweight individuals. PMID- 27709863 TI - Intra-Articular Injections in Patients with Femoroacetabular Impingement: a Prospective, Randomized, Double-blind, Cross-over Study. AB - We evaluated and compared the effectiveness of intra-articular injection of hip joint using hyaluronic acid and steroid in patients with femoroacetabular impingement (FAI). Thirty patients with FAI clinically and radiologically were enrolled and underwent hip injection using steroid (TA) or hyaluronic acid (HA) at 0-weeks with cross-over injection at 2-weeks in patients without clinical response of decrease of pain intensity less than 2-point. Patients were followed up to 12-weeks for pain intensity (Numeric rating scale, NRS: 0-10), hip disability score (HOOS), oral medication and adverse events. In 17 patients without cross-over, HOOS at 2-weeks was improved significantly in patients with HA injection (mean increase of HOOS = 13.8 with HA vs. -2.2 with TA, P = 0.031) without difference of NRS (P = 0.943). In 13 patients with cross-over, NRS was significantly improved at 2-weeks with first TA injection (mean decrease of NRS= 1.7 with first TA vs. 0.3 with first HA, P = 0.036), without difference of HOOS (P = 0.431). At 4-weeks, NRS and HOOS were significantly different according to injection drugs (NRS: 0.9 with TA first and HA later vs. 2.7 with HA first and TA later, P = 0.001; mean increase of HOOS: 5.3 with TA first and HA later vs. 10.2 with HA first and TA later, P = 0.032). Intra-articular hip injection may be effective in FAI, with faster effect of pain improvement by TA and more delayed effect of function improvement by HA. PMID- 27709864 TI - Pharmacological and Mechanical Thromboprophylaxis in Critically Ill Patients: a Network Meta-Analysis of 12 Trials. AB - Thromboprophylaxis for venous thromboembolism is widely used in critically ill patients. However, only limited evidence exists regarding the efficacy and safety of the various thromboprophylaxis techniques, especially mechanical thromboprophylaxis. Therefore, we performed meta-analysis of randomized controlled trials (RCTs) that compared the overall incidence of deep vein thrombosis (DVT) for between unfractionated heparin (UFH), low-molecular-weight heparin (LMWH), and intermittent pneumatic compression (IPC) in critically ill patients. A Bayesian random effects model for multiple treatment comparisons was constructed. The primary outcome measure was the overall incidence of DVT at the longest follow-up. The secondary outcome measure was the incidence of major bleeding, as defined by the original trials. Our analysis included 8,622 patients from 12 RCTs. The incidence of DVT was significantly lower in patients treated with UFH (OR, 0.45; 95% CrI, 0.22-0.83) or LMWH (OR, 0.38; 95% CrI, 0.18-0.72) than in patients in the control group. IPC was associated with a reduced incidence of DVT compared to the control group, but the effect was not statistically significant (OR, 0.50; 95% CrI, 0.20-1.23). The risk of DVT was similar for patients treated with UFH and LMWH (OR, 1.16; 95% CrI, 0.68-2.11). The risk of major bleeding was similar between the treatment groups in medical critically ill patients and also in critically ill patients with a high risk of bleeding. In critically ill patients, the efficacy of mechanical thromboprophylaxis in reducing the risk of DVT is not as robust as those of pharmacological thromboprophylaxis. PMID- 27709865 TI - Performance Evaluation of Five Different Disseminated Intravascular Coagulation (DIC) Diagnostic Criteria for Predicting Mortality in Patients with Complicated Sepsis. AB - Disseminated intravascular coagulation (DIC) is a major complication in sepsis patients. We compared the performance of five DIC diagnostic criteria, focusing on the prediction of mortality. One hundred patients with severe sepsis or septic shock admitted to intensive care unit (ICU) were enrolled. Routine DIC laboratory tests were performed over the first 4 days after admission. The overall ICU and 28-day mortality in DIC patients diagnosed from five criteria (International Society on Thrombosis and Haemostasis [ISTH], the Japanese Association for Acute Medicine [JAAM], the revised JAAM [R-JAAM], the Japanese Ministry of Health and Welfare [JMHW] and the Korean Society on Thrombosis and Hemostasis [KSTH]) were compared. Both KSTH and JMHW criteria showed superior performance than ISTH, JAAM and R-JAAM criteria in the prediction of overall ICU mortality in DIC patients (odds ratio 3.828 and 5.181, P = 0.018 and 0.006, 95% confidence interval 1.256 11.667 and 1.622-16.554, respectively) when applied at day 1 after admission, and survival analysis demonstrated significant prognostic impact of KSTH and JMHW criteria on the prediction of 28-day mortality (P = 0.007 and 0.049, respectively) when applied at day 1 after admission. In conclusion, both KSTH and JMHW criteria would be more useful than other three criteria in predicting prognosis in DIC patients with severe sepsis or septic shock. PMID- 27709866 TI - Relapsing Polychondritis with Central Nervous System Involvement: Experience of Three Different Cases in a Single Center. AB - Relapsing polychondritis (RP) is an autoimmune disorder characterized by inflammation in cartilaginous structures including the ears, noses, peripheral joints, and tracheobronchial tree. It rarely involves the central nervous system (CNS) but diagnosis of CNS complication of RP is challenging because it can present with varying clinical features. Herein we report 3 cases of relapsing polychondritis involving CNS with distinct manifestations and clinical courses. The first patient presented with rhombencephalitis resulting in brain edema and death. The second patient had acute cognitive dysfunction due to limbic encephalitis. He was treated with steroid pulse therapy and recovered without sequelae. The third patient suffered aseptic meningitis that presented as dementia, which was refractory to steroid and immune suppressive agents. We also reviewed literature on CNS complications of RP.

Polymer brushes are a versatile and effective means in designing membranes for applications in protein adsorption and purification, colloid stabilization, sensors, water purification, pervaporation of organic compounds, gas separations, and as stimuli responsive materials. PMID- 27709878 TI - Coherent-Interface-Assembled Ag2O-Anchored Nanofibrillated Cellulose Porous Aerogels for Radioactive Iodine Capture. AB - Nanofibrillated cellulose (NFC) has received increasing attention in science and technology because of not only the availability of large amounts of cellulose in nature but also its unique structural and physical features. These high-aspect ratio nanofibers have potential applications in water remediation and as a reinforcing scaffold in composites, coatings, and porous materials because of their fascinating properties. In this work, highly porous NFC aerogels were prepared based on tert-butanol freeze-drying of ultrasonically isolated bamboo NFC with 20-80 nm diameters. Then nonagglomerated 2-20-nm-diameter silver oxide (Ag2O) nanoparticles (NPs) were grown firmly onto the NFC scaffold with a high loading content of ~500 wt % to fabricate Ag2O@NFC organic-inorganic composite aerogels (Ag2O@NFC). For the first time, the coherent interface and interaction mechanism between the cellulose Ibeta nanofiber and Ag2O NPs are explored by high resolution transmission electron microscopy and 3D electron tomography. Specifically, a strong hydrogen between Ag2O and NFC makes them grow together firmly along a coherent interface, where good lattice matching between specific crystal planes of Ag2O and NFC results in very small interfacial straining. The resulting Ag2O@NFC aerogels take full advantage of the properties of the 3D organic aerogel framework and inorganic NPs, such as large surface area, interconnected porous structures, and supreme mechanical properties. They open up a wide horizon for functional practical usage, for example, as a flexible superefficient adsorbent to capture I- ions from contaminated water and trap I2 vapor for safe disposal, as presented in this work. The viable binding mode between many types of inorganic NPs and organic NFC established here highlights new ways to investigate cellulose-based functional nanocomposites. PMID- 27709879 TI - Real-Time Profiling of Solid-State Nanopores During Solution-Phase Nanofabrication. AB - We describe a method for simply characterizing the size and shape of a nanopore during solution-based fabrication and surface modification, using only low overhead approaches native to conventional nanopore measurements. Solution-based nanopore fabrication methods are democratizing nanopore science by supplanting the traditional use of charged-particle microscopes for fabrication, but nanopore profiling has customarily depended on microscopic examination. Our approach exploits the dependence of nanopore conductance in solution on nanopore size, shape, and surface chemistry in order to characterize nanopores. Measurements of the changing nanopore conductance during formation by etching or deposition can be analyzed using our method to characterize the nascent nanopore size and shape, beyond the typical cylindrical approximation, in real-time. Our approach thus accords with ongoing efforts to broaden the accessibility of nanopore science from fabrication through use: it is compatible with conventional instrumentation and offers straightforward nanoscale characterization of the core tool of the field. PMID- 27709881 TI - Facile Synthesis of Ge/N-Doped Carbon Spheres with Varying Nitrogen Content for Lithium Ion Battery Anodes. AB - The simple fabrication of composites of germanium nanoparticles dispersed on nitrogen-doped carbon nanospheres (Ge/NC) of varying nitrogen content and their performance in lithium ion battery anodes are reported. A heavily nitrogen-doped carbon gel was formed by condensing m-phenylenediamine with formaldehyde (PF gel); a less heavily N-doped gel was formed by condensing resorcinol and m phenylenediamine with formaldehyde (RPF-gel); and an undoped gel was formed by condensing resorcinol with formaldehyde (RF-gel). Pyrolises of the gels with GeCl4 at 750 degrees C produced nanocrystalline Ge composites with 7.5 atom % N doped carbon, termed Ge/NC (PF), with 3.9% N-doped carbon, termed Ge/NC (RPF) and undoped carbon, termed Ge/C (RF). The heavily N-doped Ge/NC (PF) anode retained a reversible capacity of 684 mAhg-1 at a specific current of 0.2 Ag-1 after 200 cycles, versus 337 mAhg-1 retained by anode made with Ge/NC (RPF) and 278 mAhg-1 retained by anode made with undoped Ge/C (RF). At a specific current 2.0 Ag-1, the capacity of the Ge/NC (PF) anode was 472 mAhg-1, versus the 210 mAhg-1 of the Ge/NC (RPF) anode and 83 mAhg-1 of the Ge/C (RF) anode. The enhanced performance of the Ge/NC (PF) anode is attributed to the better electrical conductivity of Ge/NC (PF) and to the higher density of Li+ binding defects in its N-doped carbon. PMID- 27709880 TI - TEMPO-Oxidized Nanocellulose Fiber-Directed Stable Aqueous Suspension of Plasmonic Flower-like Silver Nanoconstructs for Ultra-Trace Detection of Analytes. AB - The synthesis of shape-tuned silver (Ag) nanostructures with high plasmon characteristics has become of significant importance in in vitro diagnostic applications. Herein, we report a simple aqueous synthetic route using 2,2,6,6 tetramethylpiperidine-1-oxyl-oxidized nanocellulose fibers (T-NCFs) and trisodium citrate (TSC) that results in anisotropically grown flower-like Ag nanoconstructs (AgNFs). A detailed investigation of the concentration and sequence of the addition of reactants in the formation of these anisotropic Ag structures is presented. Our experimental results show that the mechanism underlying the formation of AgNFs is facilitated by the synergistic action of T-NCFs and TSC on the directional growth of Ag nuclei during the primary stage, which later develop into a flower-like structure by the ripening of larger particles consuming smaller Ag particles. As a result the final structure comprises flower-like morphology over which several smaller Ag particles (of size <10 nm) are adhered. The aqueous AgNF colloid exhibits high stability (zeta = -69.4 mV) and long shelf life at neutral pH (>4 months) by the efficient capping action of T-NCFs. Further, an as-synthesized nanoconstructs shows excellent surface-enhanced Raman scattering activity, which enables ultrasensitive detection of p-aminothiophenol with a concentration down to 10 aM (10-17 M) in a reproducible way. This biosupported synthesis of stable aqueous colloids of AgNF may find potential applications as a biomedical sensing platform for the trace level detection of analyte molecules. PMID- 27709882 TI - n-MoS2/p-Si Solar Cells with Al2O3 Passivation for Enhanced Photogeneration. AB - Molybdenum disulfide (MoS2) has recently emerged as a promising candidate for fabricating ultrathin-film photovoltaic devices. These devices exhibit excellent photovoltaic performance, superior flexibility, and low production cost. Layered MoS2 deposited on p-Si establishes a built-in electric field at MoS2/Si interface that helps in photogenerated carrier separation for photovoltaic operation. We propose an Al2O3-based passivation at the MoS2 surface to improve the photovoltaic performance of bulklike MoS2/Si solar cells. Interestingly, it was observed that Al2O3 passivation enhances the built-in field by reduction of interface trap density at surface. Our device exhibits an improved power conversion efficiency (PCE) of 5.6%, which to our knowledge is the highest efficiency among all bulklike MoS2-based photovoltaic cells. The demonstrated results hold the promise for integration of bulklike MoS2 films with Si-based electronics to develop highly efficient photovoltaic cells. PMID- 27709884 TI - Black Phosphorus Nanoparticle Labels for Immunoassays via Hydrogen Evolution Reaction Mediation. AB - Black phosphorus is an emerging layered material. Its nanoparticles show an increased bandgap when compared to bulk materials and they are typically fabricated by ultrasonication of macroscopic black phosphorus crystals. Here we fabricate black phosphorus nanoparticles (BP NPs) by solution based electrochemical exfoliation with bipolar electrodes, which induces opposite potentials on the opposite ends of black phosphorus macroparticles thereby leading to its decomposition into nanoparticles. BP NPs have enhanced catalytic effect on the hydrogen evolution reaction (HER) relative to black phosphorus macroparticles. We utilize black phosphorus nanoparticles as electrocatalytic tags in a competitive immunoassay for rabbit immunoglobulin G (IgG) detection. The detection signal is produced via nanoimpacts of the BP NPs followed by HER catalysis. PMID- 27709883 TI - A Unique Mdm2-Binding Mode of the 3-Pyrrolin-2-one- and 2-Furanone-Based Antagonists of the p53-Mdm2 Interaction. AB - The p53 pathway is inactivated in almost all types of cancer by mutations in the p53 encoding gene or overexpression of the p53 negative regulators, Mdm2 and/or Mdmx. Restoration of the p53 function by inhibition of the p53-Mdm2/Mdmx interaction opens up a prospect for a nongenotoxic anticancer therapy. Here, we present the syntheses, activities, and crystal structures of two novel classes of Mdm2-p53 inhibitors that are based on the 3-pyrrolin-2-one and 2-furanone scaffolds. The structures of the complexes formed by these inhibitors and Mdm2 reveal the dimeric protein molecular organization that has not been observed in the small-molecule/Mdm2 complexes described until now. In particular, the 6 chloroindole group does not occupy the usual Trp-23 pocket of Mdm2 but instead is engaged in dimerization. This entirely unique binding mode of the compounds opens new possibilities for optimization of the Mdm2-p53 interaction inhibitors. PMID- 27709885 TI - Cyclohepta[b]indoles: A Privileged Structure Motif in Natural Products and Drug Design. AB - Seven-membered rings fused with an indole are termed cyclohepta[b]indoles. Compounds exhibiting this structure motif display a broad spectrum of biological activities, ranging from inhibition of adipocyte fatty-acid-binding protein (A FABP), deacetylation of histones, inhibition of leukotriene production p53, antituberculosis activities, and anti-HIV activities. These biological profiles are found in natural products containing the cyclohepta[b]indole motif, as well as in pharmaceuticals that contain this structure motif. Therefore, the biology of molecules derived from the skeleton of cyclohepta[b]indoles, as well as cyclopenta- and cyclohexa[b]indoles, has attracted considerable interest from the pharmaceutical industry as potential therapeutics in recent years. This is reflected by more than two dozen patents that have been issued in the past decade, solely based on the cyclohepta[b]indole structure motif. The efficient preparation of highly functionalized and unsymmetrically substituted cyclohepta[b]indoles has therefore become of central interest for synthetic organic chemists. Historically, this structure motif most often has been prepared by means of a Fischer indole synthesis. Although very robust and useful, this reaction poses certain limitations. Especially unsymmetrically functionalized cyclohepta[b]indoles are not suitable for a Fischer indole type synthesis, since product mixtures are inevitable. Therefore, novel methodologies to overcome these synthetic obstacles have been developed in recent years. This Account introduces all natural products and pharmaceutical compounds exhibiting the cyclohepta[b]indole motif. The structural variability within cyclohepta[b]indole alkaloids in combination with the broad range of organisms where these alkaloids have been isolated from, strongly suggests that the cyclohepta[b]indole is somehow a "privileged" structure motif. The organisms producing these compounds range from evergreen trees (actinophyllic acid) to cyanobacteria (ambiguinines). The synthetic methodologies to construct these molecular scaffolds (natural and unnatural in origin) are in turn highlighted and discussed with regard to their potential to access highly functionalized and unsymmetrical cyclohepta[b]indoles, for which they specifically have been designed. The methods are classified with respect to reaction type and whether or not they are enantioselective. Finally, the syntheses of cyclohepta[b]indole natural products are presented, thereby in each case, focusing on the construction of this structure motif in the course of the respective total synthesis. As a conclusion, we end by contrasting the methodological progress in the field with the actual successful application of the newly developed methods to the synthesis of complex structures to pinpoint the urgent requirement for further synthetic development for efficient synthetic design of this "privileged" structure motif. PMID- 27709886 TI - The Dynamics Behind the Affinity: Controlling Heme-Gas Affinity via Geminate Recombination and Heme Propionate Conformation in the NO Carrier Cytochrome c'. AB - Nitric oxide (NO) sensors are heme proteins which may also bind CO and O2. Control of heme-gas affinity and their discrimination are achieved by the structural properties and reactivity of the heme and its distal and proximal environments, leading to several energy barriers. In the bacterial NO sensor cytochrome c' from Alcaligenes xylosoxidans (AXCP), the single Leu16Ala distal mutation boosts the affinity for gas ligands by a remarkable 106-108-fold, transforming AXCP from one of the lowest affinity gas binding proteins to one of the highest. Here, we report the dynamics of diatomics after photodissociation from wild type and L16A-AXCP over 12 orders of magnitude in time. For the L16A variant, the picosecond geminate rebinding of both CO and NO appears with an unprecedented 100% yield, and no exit of these ligands from protein to solvent could be observed. Molecular dynamic simulations saliently demonstrate that dissociated CO stays within 4 A from Fe2+, in contrast to wild-type AXCP. The L16A mutation confers a heme propionate conformation and docking site which traps the diatomics, maximizing the probability of recombination and directly explaining the ultrahigh affinities for CO, NO, and O2. Overall, our results point to a novel mechanism for modulating heme-gas affinities in proteins. PMID- 27709887 TI - Polydopamine Nanoparticles Modulating Stimuli-Responsive PNIPAM Hydrogels with Cell/Tissue Adhesiveness. AB - Stimuli-responsive hydrogels can respond to stimuli by phase transformation or volume change and exhibit specific functions. Near-infrared (NIR)-responsive hydrogel is a type of stimuli-responsive hydrogel, which can be precisely controlled by altering the radiation intensity, exposure time of the light source, and irradiation sites. Here, polydopamine nanoparticles (PDA-NPs) were introduced into a poly(N-isopropylacrylamide) (PNIPAM) network to fabricate a PDA NPs/PNIPAM hydrogel with NIR responsibility, self-healing ability, and cell/tissue adhesiveness. After incorporation of PDA-NPs into the hydrogel, the PDA-NPs/PNIPAM hydrogel showed phase transitions and volume changes in response to NIR. Thus, the hydrogel can achieve triple response effects, including pulsatile drug release, NIR-driven actuation, and NIR-assisted healing. After coating PDA-NPs onto hydrogel surfaces, the hydrogel showed improved cell affinity, good tissue adhesiveness, and growth factor/protein immobilization ability because of reactive catechol groups on PDA-NPs. The tissue adhesion strength to porcine skin was as high as 90 KPa. In vivo full-skin defect experiments demonstrated that PDA-NPs coating on the hydrogel and an immobilized growth factor had a synergistic effect on accelerating wound healing. In summary, we combined thermosensitive PNIPAM and mussel-inspired PDA-NPs to form a NIR responsive hydrogel, which may have potential applications for chemical and physical therapies. PMID- 27709888 TI - Polymerization of Monomeric Ionic Liquid Confined within Uniaxial Alumina Pores as a New Way of Obtaining Materials with Enhanced Conductivity. AB - Broadband dielectric spectroscopy (BDS) and differential scanning calorimetry (DSC) have been employed to probe dynamics and charge transport of 1-butyl-3 vinylimidazolium bis(trifluoromethanesulfonyl)imide ([bvim][NTf2]) confined in native uniaxial AAO pores as well as to study kinetics of radical polymerization of the examined compound as a function of the degree of confinement. Subsequently, the electronic conductivity of the produced polymers was investigated. As observed, polymerization carried out at T = 363 K proceeds faster under confinement with some saturation effect observed for the sample in pores of smaller diameter. Obtained results were discussed in the context of the very recent reports showing that the free volume of the confined material is higher with respect to the bulk one. It was also noted that conductivity of poly[bvim][NTf2] is significantly higher with respect to the macromolecules obtained upon bulk polymerization. Moreover, charge transport of the confined macromolecules is even higher when compared to the bulk monomeric ionic liquid at some thermodynamic conditions. Additionally, the molecular weight, Mw, of the confined-synthesized polymers is significantly higher with respect to the bulk synthesized material. Interestingly, both parameters, (i) the enhancement of sigmadc and (ii) the increase in Mw, can be tuned and controlled by the application of the appropriate confinement. Consequently, those results are quite promising in the context of development of the fabrication of polymerized ionic liquids (PILs) nanomaterials with unique properties and morphologies, which can be further easily applied in the field of nanotechnology. PMID- 27709889 TI - Silicon-Reduced Graphene Oxide Self-Standing Composites Suitable as Binder-Free Anodes for Lithium-Ion Batteries. AB - Silicon-reduced graphene oxide (Si-rGO) composites processed as self-standing aerogels (0.2 g cm-3) and films (1.5 g cm-3) have been prepared by the thermal reduction of composites formed between silicon nanoparticles and a suspension of graphene oxide (GO) in ethanol. The characterization of the samples by different techniques (X-ray diffraction, Raman, thermogravimetric analysis, and scanning electron microscopy) show that in both cases the composites are formed by rGO sheets homogeneously decorated with 50 nm silicon nanoparticles with silicon contents of ~40% wt. The performances of these self-standing materials were tested as binder-free anodes in lithium-ion batteries (LIBs) in a half cell configuration under two different galvanostatic charge-discharge cutoff voltages (75 and 50 mV). The results show that the formation of a solid electrolyte interphase (SEI) is favored in composites processed as aerogels due to its large exposed surface, which prevents the activation of silicon when they are cycled within the 2 to 0.075 V voltage windows. It is also found that the composites processed in the form of self-standing films exhibit good stability over the first 100 cycles, high reversible specific capacity per mass of electrode (~750 mAh g-1), areal capacities that reach 0.7 mAh cm-2, and high Coulombic efficiencies (80% for the first charge-discharge cycle and over 99% in the subsequent cycles).

AB - Bacterial colonization and subsequent formation of biofilms onto surfaces of medical devices and implants is a major source of nosocomial infections. Most antibacterial coatings to combat infections are either metal-based or nondegradable-polymer-based and hence limited by their nondegradability and unpredictable toxicity. Moreover, to combat infections effectively, the coatings are required to display simultaneous antibacterial and antibiofilm activity. Herein we report biocompatible and biodegradable coatings based on organo-soluble quaternary chitin polymers which were immobilized noncovalently onto surfaces as bactericidal paint. The polycationic paint was found to be active against both drug-sensitive and -resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecium (VRE), and beta-lactam-resistant Klebsiella pneumoniae. The cationic polymers were shown to interact with the negatively charged bacterial cell membrane and disrupt the membrane integrity, thereby causing leakage of intracellular constituents and cell death upon contact. Importantly, surfaces coated with the polymers inhibited formation of biofilms against both Gram-positive S. aureus and Gram-negative E. coli, two of the most clinically important bacteria that form biofilms. Surfaces coated with the polymers displayed negligible toxicity against human erythrocytes and embryo kidney cells. Notably, the polymers were shown to be susceptible toward lysozyme. Furthermore, subcutaneous implantation of polymer discs in rats led to 15-20% degradation in 4 weeks thereby displaying their biodegradability. In a murine model of subcutaneous infection, polymer-coated medical-grade catheter reduced MRSA burden by 3.7 log compared to that of noncoated catheter. Furthermore, no biofilm development was observed on the coated catheters under in vivo conditions. The polycationic materials thus developed herein represent a novel class of safe and effective coating agents for the prevention of device associated infections.

PMID- 27709893 TI - Development and Calibration of an Organic-Diffusive Gradients in Thin Films Aquatic Passive Sampler for a Diverse Suite of Polar Organic Contaminants. AB - A unique configuration of the diffusive gradients in thin films sampler for polar organics (o-DGT) without a poly(ether sulfone) membrane was developed, calibrated, and field-evaluated. Diffusion coefficients (D) through agarose diffusive gels ranged from (1.02 to 4.74) * 10-6 cm2/s for 34 pharmaceuticals and pesticides at 5, 13, and 23 degrees C. Analyte-specific diffusion-temperature plots produced linear (r2 > 0.85) empirical relationships whereby D could be estimated at any environmentally relevant temperature (i.e., matched to in situ water conditions). Linear uptake for all analytes was observed in a static renewal calibration experiment over 25 days except for three macrolide antibiotics, which reached saturation at 300 ng (~15 d). Experimental sampling rates ranged from 8.8 to 16.1 mL/d and were successfully estimated with measured and modeled D within 19% and 30% average relative error, respectively. Under slow flowing (2.4 cm/s) and static conditions, the in situ diffusive boundary layer (DBL) thickness ranged from 0.023 to 0.075 cm, resulting in a maximum contribution to mass transfer of <45%. Estimated water concentrations by o-DGT at a wastewater treatment plant agreed well with grab samples and appeared to be less influenced by the boundary layer compared to that of polar organic chemical integrative samplers (POCIS) deployed simultaneously. The o-DGT sampler is a promising monitoring tool that is largely insensitive to the DBL under typical flow conditions, facilitating the application of measured/modeled diffusion-based sampling rates. This significantly reduces the need for sampler calibration, making o-DGT more widely applicable, reliable, and cost-effective compared to current polar passive samplers.

AB - An impressive development has been achieved toward the production of well-defined "smart" inorganic nanoparticles, in which the physicochemical properties can be controlled and predicted to a high degree of accuracy. Nanoparticle design is indeed highly advanced, multimodal and multitargeting being the norm, yet we do not fully understand the obstacles that nanoparticles face when used in vivo. Increased cooperation between chemists and biochemists, immunologists and physicists, has allowed us to think outside the box, and we are slowly starting to understand the interactions that nanoparticles undergo under more realistic situations. Importantly, such an understanding involves awareness about the limitations when assessing the influence of such inorganic nanoparticles on biological entities and vice versa, as well as the development of new validation strategies. PMID- 27709894 TI - In Vitro Toxicity Evaluation of Lignin-(Un)coated Cellulose Based Nanomaterials on Human A549 and THP-1 Cells. AB - A significant amount of research toward commercial development of cellulose based nanomaterials (CNM) is now in progress with some potential applications. Using human A549 and THP-1 cells, we evaluated the biological responses of various CNMs, made out of similar material but with functional and morphological variations. While A549 cells displayed minimal or no cytotoxic responses following exposure to CNMs, THP-1 cells were more susceptible to cytotoxicity, cellular damage and inflammatory responses. Further analysis of these biological responses evaluated using hierarchical clustering approaches was effective in discriminating (dis)-similarities of various CNMs studied and identified potential inflammatory factors contributing to cytotoxicity. No correlation between cytotoxicity and surface properties of CNMs was found. This study clearly highlights that, in addition to the source and characteristics of CNMs, cell type specific differences in the recognition/uptake of CNMs along with their inherent capability to respond to external stimuli are crucial for assessing the toxicity of CNMs. PMID- 27709895 TI - Multiplex Biosensing Based on Highly Sensitive Magnetic Nanolabel Quantification: Rapid Detection of Botulinum Neurotoxins A, B, and E in Liquids. AB - We present a multiplex quantitative lateral flow (LF) assay for simultaneous on site detection of botulinum neurotoxin (BoNT) types A, B, and E in complex matrixes, which is innovative by virtually no sacrifice in performance while transition from the single-plex assays and by characteristics on the level of laboratory quantitative methods. The novel approach to easy multiplexing is realized via joining an on-demand set of single-plex LF strips, which employ magnetic nanolabels, into a miniature cylinder cartridge that mimics LF strip during all assay stages. The cartridge is read out by an original portable multichannel reader based on the magnetic particle quantification technique. The developed reader offers the unmatched 60 zmol detection limit and 7-order linear dynamic range for volumetric registration of magnetic labels inside a cartridge of several millimeters in diameter regardless of its optical transparency. Each of the test strips, developed here as building blocks for the multiplex assay, can be used "as is" for autonomous quantitative single-plex detection with the same measuring setup, exhibiting the limits of detection (LOD) of 0.22, 0.11, and 0.32 ng/mL for BoNT-A, -B, and -E, respectively. The proposed multiplex assay has demonstrated the remarkably similar LOD values of 0.20, 0.12, 0.35 ng/mL under the same conditions. The multiplex assay performance was successfully validated by BoNT detection in milk and apple and orange juices. The developed methods can be extended to other proteins and used for rapid multianalyte tests for point-of care in vitro diagnostics, food analysis, biosafety and environmental monitoring, forensics, and security, etc. PMID- 27709896 TI - Tissue Characterization with Quantitative High-Resolution Magic Angle Spinning Chemical Exchange Saturation Transfer Z-Spectroscopy. AB - Chemical exchange saturation transfer (CEST) provides sensitive magnetic resonance (MR) contrast for probing dilute compounds via exchangeable protons, serving as an emerging molecular imaging methodology. CEST Z-spectrum is often acquired by sweeping radiofrequency saturation around bulk water resonance, offset by offset, to detect CEST effects at characteristic chemical shift offsets, which requires prolonged acquisition time. Herein, combining high resolution magic angle spinning (HRMAS) with concurrent application of gradient and rf saturation to achieve fast Z-spectral acquisition, we demonstrated the feasibility of fast quantitative HRMAS CEST Z-spectroscopy. The concept was validated with phantoms, which showed excellent agreement with results obtained from conventional HRMAS MR spectroscopy (MRS). We further utilized the HRMAS Z spectroscopy for fast ex vivo quantification of ischemic injury with rodent brain tissues after ischemic stroke. This method allows rapid and quantitative CEST characterization of biological tissues and shows potential for a host of biomedical applications. PMID- 27709898 TI - Aerosol Chemistry Resolved by Mass Spectrometry: Linking Field Measurements of Cloud Condensation Nuclei Activity to Organic Aerosol Composition. AB - Aerosol hygroscopic properties were linked to its chemical composition by using complementary online mass spectrometric techniques in a comprehensive chemical characterization study at a rural mountaintop station in central Germany in August 2012. In particular, atmospheric pressure chemical ionization mass spectrometry ((-)APCI-MS) provided measurements of organic acids, organosulfates, and nitrooxy-organosulfates in the particle phase at 1 min time resolution. Offline analysis of filter samples enabled us to determine the molecular composition of signals appearing in the online (-)APCI-MS spectra. Aerosol mass spectrometry (AMS) provided quantitative measurements of total submicrometer organics, nitrate, sulfate, and ammonium. Inorganic sulfate measurements were achieved by semionline ion chromatography and were compared to the AMS total sulfate mass. We found that up to 40% of the total sulfate mass fraction can be covalently bonded to organic molecules. This finding is supported by both on- and offline soft ionization techniques, which confirmed the presence of several organosulfates and nitrooxy-organosulfates in the particle phase. The chemical composition analysis was compared to hygroscopicity measurements derived from a cloud condensation nuclei counter. We observed that the hygroscopicity parameter (kappa) that is derived from organic mass fractions determined by AMS measurements may overestimate the observed kappa up to 0.2 if a high fraction of sulfate is bonded to organic molecules and little photochemical aging is exhibited. PMID- 27709897 TI - Comparing Gene Silencing and Physiochemical Properties in siRNA Bound Cationic Star-Polymer Complexes. AB - The translation of siRNA into clinical therapies has been significantly delayed by issues surrounding the delivery of naked siRNA to target cells. Here we investigate siRNA delivery by cationic acrylic polymers developed by Reversible Addition-Fragmentation chain Transfer (RAFT) mediated free radical polymerization. We investigated cell uptake and gene silencing of a series of siRNA-star polymer complexes both in the presence and absence of a protein "corona". Using a multidisciplinary approach including quantitative nanoscale mechanical-atomic force microscopy, dynamic light scattering and nanoparticle tracking analysis we have characterized the nanoscale morphology, stiffness, and surface charge of the complexes with and without the protein corona. This is one of the first examples of a comprehensive physiochemical analysis of siRNA-polymer complexes being performed alongside in vitro biological assays, allowing us to describe a set of desirable physical features of cationic polymer complexes that promote gene silencing. Multifaceted studies such as this will improve our understanding of structure-function relationships in nanotherapeutics, facilitating the rational design of polymer-mediated siRNA delivery systems for novel treatment strategies. PMID- 27709899 TI - PGMA-Based Cationic Nanoparticles with Polyhydric Iodine Units for Advanced Gene Vectors. AB - It is crucial for successful gene delivery to develop safe, effective, and multifunctional polycations. Iodine-based small molecules are widely used as contrast agents for CT imaging. Herein, a series of star-like poly(glycidyl methacrylate) (PGMA)-based cationic vectors (II-PGEA/II) with abundant flanking polyhydric iodine units are prepared for multifunctional gene delivery systems. The proposed II-PGEA/II star vector is composed of one iohexol intermediate (II) core and five ethanolamine (EA) and II-difunctionalized PGMA arms. The amphipathic II-PGEA/II vectors readily self-assemble into well-defined cationic nanoparticles, where massive hydroxyl groups can establish a hydration shell to stabilize the nanoparticles. The II introduction improves cell viabilities of polycations. Moreover, by controlling the suitable amount of introduced II units, the resultant II-PGEA/II nanoparticles can produce fairly good transfection performances in different cell lines. Particularly, the II-PGEA/II nanoparticles induce much better in vitro CT imaging abilities in tumor cells than iohexol (one commonly used commercial CT contrast agent). The present design of amphipathic PGMA-based nanoparticles with CT contrast agents would provide useful information for the development of new multifunctional gene delivery systems. PMID- 27709900 TI - Aerosol Chemistry Resolved by Mass Spectrometry: Insights into Particle Growth after Ambient New Particle Formation. AB - Atmospheric oxidation of volatile organic compounds (VOCs) yields a large number of different organic molecules which comprise a wide range of volatility. Depending on their volatility, they can be involved in new particle formation and particle growth, thus affecting the number concentration of cloud condensation nuclei in the atmosphere. Here, we identified oxidation products of VOCs in the particle phase during a field study at a rural mountaintop station in central Germany. We used atmospheric pressure chemical ionization mass spectrometry (( )APCI-MS) and aerosol mass spectrometry for time-resolved measurements of organic species and of the total organic aerosol (OA) mass in the size range of 0.02-2.5 and 0.05-0.6 MUm, respectively. The elemental composition of organic molecules was determined by offline analysis of colocated PM 2.5 filter samples using liquid chromatography coupled to electrospray ionization ultrahigh-resolution mass spectrometry. We found extremely low volatile organic compounds, likely from sesquiterpene oxidation, being the predominant signals in the (-)APCI-MS mass spectrum during new particle formation. Low volatile organic compounds started to dominate the spectrum when the newly formed particles were growing to larger diameters. Furthermore, the APCI-MS mass spectra pattern indicated that the average molecular weight of the OA fraction ranged between 270 and 340 amu, being inversely related to OA mass. Our observations can help further the understanding of which biogenic precursors and which chemical processes drive particle growth after atmospheric new-particle formation. PMID- 27709901 TI - Effects of C60 on the Photochemical Formation of Reactive Oxygen Species from Natural Organic Matter. AB - Buckminsterfullerenes (C60) are widely used nanomaterials that are present in surface water. The combination of C60 and humic acid (HA) generates reactive oxygen species (ROS) under solar irradiation, but this process is not well understood. Thus, the present study focused on the photochemical formation of singlet oxygen (1O2), hydroxyl radical (HO*)-like species, superoxide radicals (O2*-), hydrogen peroxide (H2O2), and triplet excited states (3C60*/3HA*) in solutions containing both C60 and HA. The quantum yield coefficients of excited triplet states (fTMP) and apparent quantum yields of ROS were measured and compared to the calculated values, which were based on the conservative mixing model. Although C60 proved to have only a slight impact on the 1O2 formation from HA, C60 played a key role in the inhibition of O2*-. The photochemical formation of H2O2 followed the conservative mixing model due to the reaction of C60*- with HO2*/O2*-, and the biomolecular reaction rate constant has been measured as (7.4 +/- 0.6) * 106 M-1 s-1. The apparent fTMP was significantly lower than the calculated value, indicating that the steric effect of HA was significant in the reaction of 3C60* with the TMP probe. In contrast, C60 did not have an effect on the photochemical formation of HO* from HA, suggesting that HO* is elevated from the hydrophilic surface of HA. The aforementioned results may be useful for predicting the photochemical influence of C60 on aqueous environments. PMID- 27709902 TI - Enrichment of Saccharides and Divalent Cations in Sea Spray Aerosol During Two Phytoplankton Blooms. AB - Sea spray aerosol (SSA) is a globally important source of particulate matter. A mesocosm study was performed to determine the relative enrichment of saccharides and inorganic ions in nascent fine (PM2.5) and coarse (PM10-2.5) SSA and the sea surface microlayer (SSML) relative to bulk seawater. Saccharides comprise a significant fraction of organic matter in fine and coarse SSA (11 and 27%, respectively). Relative to sodium, individual saccharides were enriched 14-1314 fold in fine SSA, 3-138-fold in coarse SSA, but only up to 1.0-16.2-fold in SSML. Enrichments in SSML were attributed to rising bubbles that scavenge surface active species from seawater, while further enrichment in fine SSA likely derives from bubble films. Mean enrichment factors for major ions demonstrated significant enrichment in fine SSA for potassium (1.3), magnesium (1.4), and calcium (1.7), likely because of their interactions with organic matter. Consequently, fine SSA develops a salt profile significantly different from that of seawater. Maximal enrichments of saccharides and ions coincided with the second of two phytoplankton blooms, signifying the influence of ocean biology on selective mass transfer across the ocean-air interface. PMID- 27709903 TI - In Situ Molecular Imaging of the Biofilm and Its Matrix. AB - Molecular mapping of live biofilms at submicrometer resolution presents a grand challenge. Here, we present the first chemical mapping results of biofilm extracellular polymeric substance (EPS) in biofilms using correlative imaging between super resolution fluorescence microscopy and liquid time-of-flight secondary ion mass spectrometry (TOF-SIMS). Shewanella oneidensis is used as a model organism. Heavy metal chromate (Cr2O72-) anions consisting of chromium Cr(VI) was used as a model environmental stressor to treat the biofilms. Of particular interest, biologically relevant water clusters have been first observed in the biofilms. Characteristic fragments of biofilm matrix components such as proteins, polysaccharides, and lipids can be spatially imaged. Furthermore, characteristic fatty acids (e.g., palmitic acid), quinolone signal, and riboflavin fragments were found to respond after the biofilm is treated with Cr(VI), leading to biofilm dispersal. Significant changes in water clusters and quorum sensing signals indicative of intercellular communication in the aqueous environment were observed, suggesting that they might result in fatty acid synthesis and inhibition of riboflavin production. The Cr(VI) reduction seems to follow the Mtr pathway leading to Cr(III) formation. Our approach potentially opens a new avenue for mechanistic insight of microbial community processes and communications using in situ imaging mass spectrometry and super resolution optical microscopy. PMID- 27709904 TI - Endotoxins: The Critical Risk Factor in Reclaimed Water via Inhalation Exposure. AB - The use of reclaimed water for nonpotable uses requires consideration of potential adverse health effects. Considering that inhalation can be a significant route of transmission of microorganisms and inflammatory agents, this study used a mouse model to test the possible adverse effects of reclaimed water use during car washing where aerosols are generated. Intensive innate immune responses were found in the lungs after acute exposure, and the lavage polymorphonuclear cell proportion was the most sensitive end point. Four types of evidence are presented to demonstrate that the main risk factor that initiates innate inflammation is the free endotoxin. (1) Small molecules (<10 kDa) cannot induce inflammation. (2) The endotoxin levels of 11 water samples from five different plants showed positive correlations with inflammatory responses. (3) Actual water samples showed similar activities with free endotoxins other than bacterially bound endotoxins. (4) Specific removal of endotoxins with polymyxin B affinity chromatography further confirmed the role of free endotoxins. It is noteworthy that 62.9% of the investigated tertiary-treated water had endotoxin levels higher than the allowable acute threshold (120 endotoxin units/mL) under the hypothesized car wash condition, which strongly suggests the need to carefully consider the water treatment steps required to produce safe water for various reclaimed water end uses. PMID- 27709906 TI - Fully Automated Portable Comprehensive 2-Dimensional Gas Chromatography Device. AB - We developed a fully automated portable 2-dimensional (2-D) gas chromatography (GC x GC) device, which had a dimension of 60 cm * 50 cm * 10 cm and weight less than 5 kg. The device incorporated a micropreconcentrator/injector, commercial columns, micro-Deans switches, microthermal injectors, microphotoionization detectors, data acquisition cards, and power supplies, as well as computer control and user interface. It employed multiple channels (4 channels) in the second dimension (2D) to increase the 2D separation time (up to 32 s) and hence 2D peak capacity. In addition, a nondestructive flow-through vapor detector was installed at the end of the 1D column to monitor the eluent from 1D and assist in reconstructing 1D elution peaks. With the information obtained jointly from the 1D and 2D detectors, 1D elution peaks could be reconstructed with significantly improved 1D resolution. In this Article, we first discuss the details of the system operating principle and the algorithm to reconstruct 1D elution peaks, followed by the description and characterization of each component. Finally, 2-D separation of 50 analytes, including alkane (C6-C12), alkene, alcohol, aldehyde, ketone, cycloalkane, and aromatic hydrocarbon, in 14 min is demonstrated, showing the peak capacity of 430-530 and the peak capacity production of 40-80/min.

AB - Low-molecular weight heparins (LMWH) prepared by partial depolymerization of unfractionated heparin are used globally to treat coagulation disorders on an outpatient basis. Patent protection for several LMWH has expired and abbreviated new drug applications have been approved by the Food and Drug Administration. As a result, reverse engineering of LMWH for biosimilar LMWH has become an active global endeavor. Traditionally, the molecular weight distributions of LMWH preparations have been determined using size exclusion chromatography (SEC) with optical detection. Recent advances in liquid chromatography-mass spectrometry methods have enabled exact mass measurements of heparin saccharides roughly up to degree-of-polymerization 20, leaving the high molecular weight half of the LMWH preparation unassigned. We demonstrate a new LC-MS system capable of determining the exact masses of complete LMWH preparations, up to dp30. This system employed an ion suppressor cell to desalt the chromatographic effluent online prior to the electrospray mass spectrometry source. We expect this new capability will impact the ability to define LMWH mixtures favorably. PMID- 27709907 TI - Synthesis and Functionalization of Porphyrins through Organometallic Methodologies. AB - This review focuses on the postfunctionalization of porphyrins and related compounds through catalytic and stoichiometric organometallic methodologies. The employment of organometallic reactions has become common in porphyrin synthesis. Palladium-catalyzed cross-coupling reactions are now standard techniques for constructing carbon-carbon bonds in porphyrin synthesis. In addition, iridium- or palladium-catalyzed direct C-H functionalization of porphyrins is emerging as an efficient way to install various substituents onto porphyrins. Furthermore, the copper-mediated Huisgen cycloaddition reaction has become a frequent strategy to incorporate porphyrin units into functional molecules. The use of these organometallic techniques, along with the traditional porphyrin synthesis, now allows chemists to construct a wide range of highly elaborated and complex porphyrin architectures. PMID- 27709908 TI - Genetic, Structural, and Phenotypic Properties of MS2 Coliphage with Resistance to ClO2 Disinfection. AB - Common water disinfectants like chlorine have been reported to select for resistant viruses, yet little attention has been devoted to characterizing disinfection resistance. Here, we investigated the resistance of MS2 coliphage to inactivation by chlorine dioxide (ClO2). ClO2 inactivates MS2 by degrading its structural proteins, thereby disrupting the ability of MS2 to attach to and infect its host. ClO2-resistant virus populations emerged not only after repeated cycles of ClO2 disinfection followed by regrowth but also after dilution-regrowth cycles in the absence of ClO2. The resistant populations exhibited several fixed mutations which caused the substitution of ClO2-labile by ClO2-stable amino acids. On a phenotypic level, these mutations resulted in a more stable host binding during inactivation compared to the wild-type, thus resulting in a greater ability to maintain infectivity. This conclusion was supported by cryo electron microscopy reconstruction of the virus particle, which demonstrated that most structural modification occurred in the putative A protein, an important binding factor. Resistance was specific to the inactivation mechanism of ClO2 and did not result in significant cross-resistance to genome-damaging disinfectants. Overall, our data indicate that resistant viruses may emerge even in the absence of ClO2 pressure but that they can be inactivated by other common disinfectants. PMID- 27709909 TI - Engineering Biological C-H Functionalization Leads to Allele-Specific Regulation of Histone Demethylases. AB - Oxidative C-H hydroxylation of methyl groups, followed by their removal from DNA, RNA or histones, is an epigenetic process critical to transcriptional reprogramming and cell fate determination. This reaction is catalyzed by Fe(II) dependent dioxygenases using the essential metabolite 2-ketoglutarate (2KG) as a cofactor. Given that the human genome encodes for more than 60 2KG-dependent dioxygenases, assigning their individual functions remains a significant challenge. Here we describe a protein-ligand interface engineering approach to break the biochemical degeneracy of these enzymes. Using histone lysine demethylase 4 (KDM4) as a proof-of-concept, we show that the enzyme active site can be expanded to employ bulky 2KG analogues that do not sensitize wild type demethylases. We establish the orthogonality, substrate specificity and catalytic competency of the engineered demethylation apparatus in biochemical assays. We further demonstrate demethylation of cognate substrates in physiologically relevant settings. Our results provide a para-digm for rapid and conditional manipulation of histone deme-thylases to uncloak their isoform-specific functions. PMID- 27709910 TI - Scenarios for Low Carbon and Low Water Electric Power Plant Operations: Implications for Upstream Water Use. AB - Electric sector water use, in particular for thermoelectric operations, is a critical component of the water-energy nexus. On a life cycle basis per unit of electricity generated, operational (e.g., cooling system) water use is substantially higher than water demands for the fuel cycle (e.g., natural gas and coal) and power plant manufacturing (e.g., equipment and construction). However, could shifting toward low carbon and low water electric power operations create trade-offs across the electricity life cycle? We compare business-as-usual with scenarios of carbon reductions and water constraints using the MARKet ALlocation (MARKAL) energy system model. Our scenarios show that, for water withdrawals, the trade-offs are minimal: operational water use accounts for over 95% of life cycle withdrawals. For water consumption, however, this analysis identifies potential trade-offs under some scenarios. Nationally, water use for the fuel cycle and power plant manufacturing can reach up to 26% of the total life cycle consumption. In the western United States, nonoperational consumption can even exceed operational demands. In particular, water use for biomass feedstock irrigation and manufacturing/construction of solar power facilities could increase with high deployment. As the United States moves toward lower carbon electric power operations, consideration of shifting water demands can help avoid unintended consequences. PMID- 27709911 TI - Catalytic, Regioselective Hydrocarbofunctionalization of Unactivated Alkenes with Diverse C-H Nucleophiles. AB - Reactions that forge carbon-carbon (C-C) bonds are the bedrock of organic synthesis, widely used across the chemical sciences. We report a transformation that enables C-C bonds to be constructed from two classes of commonly available starting materials, alkenes and carbon-hydrogen (C-H) bonds. The reaction employs a palladium(II) catalyst and utilizes a removable directing group to both control the regioselectivity of carbopalladation and enable subsequent protodepalladation. A wide range of alkenes and C-H nucleophiles, including 1,3 dicarbonyls, aryl carbonyls, and electron-rich aromatics, are viable reaction partners, allowing Michael-type reactivity to be expanded beyond alpha,beta unsaturated carbonyl compounds to unactivated alkenes. Applications of this transformation in drug diversification and natural product total synthesis are described. Stoichiometric studies support each of the proposed steps in the catalytic cycle.

AB - The title phosphinidene complex reacted at room temperature with CS2 and SCNPh to give the phosphanyl derivatives [Mo2Cp{MU-kappa2P,S:kappa1S',eta5 P(CS2)C5H4}(CO)2(eta6-HMes*)] and [Mo2Cp{MU-kappa2P,S:kappa1P,eta5 P(C(NPh)S)C5H4}(CO)2(eta6-HMes*)], respectively (Mes* = 2,4,6-C6H2tBu3), which result from a [2 + 2] cycloaddition of a C?S bond in the organic reagent to the Mo?P bond of the phosphinidene complex, with further insertion of S into the remaining Mo-P bond, in the CS2 reaction. The title complex also reacted with diazoalkanes N2CRR' at room temperature to give the corresponding phosphaalkene derivatives [Mo2Cp{MU-eta2:kappa1P,eta5-P(CRR')C5H4}(CO)2(eta6-HMes*)] (CRR' = CH2, CPh2, CH(SiMe3)). These products follow from a formal [2 + 1] cycloaddition of the carbene CRR' fragment to the Mo?P bond of the parent compound but were shown to proceed through a [3 + 2] cycloaddition of the diazoalkane molecule, followed by N2 elimination. The diazomethane reaction allowed the identification at low temperature of a stabilized form of the intermediate product, the phosphanyl complex [Mo2Cp{MU-kappa2P,N:kappa1P,eta5-P(CHN2H)C5H4}(CO)2(eta6 HMes*)], which follows from a reversible 1,3-shift of a methylenic H atom from C to N. It was concluded that all of the above cycloaddition reactions are initiated by heteroatom coordination of the unsaturated organic molecule to the MoCp(CO)2 fragment in the parent phosphinidene complex, this triggering the P-C bond formation step which leads to the products eventually isolated. The structures of the new complexes were determined by spectroscopic, diffractometric, and (in some cases) density functional theory methods.

These are trapped by N-tethered alkenes to provide complex perhydroisoindoles. PMID- 27709915 TI - Exploiting Pressure To Induce a "Guest-Blocked" Spin Transition in a Framework Material. AB - A new functionalized 1,2,4-triazole ligand, 4-[(E)-2-(5-methyl-2-thienyl)vinyl] 1,2,4-triazole (thiome), was prepared to assess the broad applicability of strategically producing multistep spin transitions in two-dimensional Hofmann type materials of the type [FeIIPd(CN)4(R-1,2,4-trz)2].nH2O (R-1,2,4-trz = a 4 functionalized 1,2,4-triazole ligand). A variety of structural and magnetic investigations on the resultant framework material [FeIIPd(CN)4(thiome)2].2H2O (A.2H2O) reveal that a high-spin (HS) to low-spin (LS) transition is inhibited in A.2H2O due to a combination of guest and ligand steric bulk effects. The water molecules can be reversibly removed with retention of the porous host framework and result in the emergence of an abrupt and hysteretic one-step spin transition due to the removal of guest internal pressure. A spin transition can, furthermore, be induced in A.2H2O (0-0.68 GPa) under hydrostatic pressure, as evidenced by variable-pressure structure and magnetic studies, resulting in a two step spin transition at ambient temperatures at 0.68 GPa. The presence of a two step spin crossover (SCO) in A.2H2O under hydrostatic pressure compared to a one step SCO in A at ambient pressure is discussed in terms of the relative ability of each phase to accommodate mixed HS/LS states according to differing lattice flexibilities.

AB - Both in vivo and ex vivo observations support the hypothesis that bone mineral formation proceeds via disordered precursor phases. The characteristics of the precursor phases are not well defined, but octacalcium phosphate-like, amorphous calcium phosphate-like, and HPO42--enriched phases were detected. Here we use in vivo Raman spectroscopy and high-resolution wide-angle X-ray diffraction (WAXD) to characterize and map at 2 MUm resolution the mineral phases in the rapidly forming tail fin bones of living zebrafish larvae and zebrafish larvae immediately after sacrifice, respectively. Raman spectroscopy shows the presence of an acidic disordered calcium phosphate phase with additional characteristic features of HPO42- at the bone-cell interface. The complexity in the position and shape of the nu1 PO4 peak viewed by in vivo Raman spectroscopy emphasizes the heterogeneity of the mineral during bone formation. WAXD detects an additional isolated peak, appearing alone or together with the characteristic diffraction pattern of carbonated hydroxyapatite. This unidentified phase is located at the interface between the mature bone and the surrounding tissue, similar to the location at which the disordered phase was observed by Raman spectroscopy. The variable peak positions and profiles support the notion that this is an unstable disordered precursor phase, which conceivably crystallized during the X-ray diffraction measurement. Interestingly, this precursor phase is co-aligned with the c-axes of the mature bone crystals and thus is in intimate relation with the surrounding collagen matrix. We conclude that a major disordered precursor mineral phase containing HPO42- is part of the deposition pathway of the rapidly forming tail fin bones of the zebrafish.

AB - Solid-state superstructures, resulting from assemblies programmed by homochirality, are attracting considerable attention. In addition, artificial double-helical architectures are being investigated, especially in relation to the ways in which homochiral small molecules can be induced to yield helical forms as a result of chiral induction. Herein, we report the highly specific self assembly upon crystallization of a double-helical superstructure from an enantiopure macrocyclic dimer which adopts two diastereoisomeric conformations in a molar ratio of 1.5:1 in dimethyl sulfoxide. These two conformational diastereoisomers self-organize-and self-sort-in the crystalline phase in equimolar proportions to form two single-handed helices which are complementary to each other, giving rise to the assembly of a double helix that is stabilized by intermolecular [C-H...O] and pi-pi stacking interactions. The observed self sorting phenomenon occurs on going from a mixed-solvent system containing two equilibrating conformational diastereoisomers, presumably present in unequal molar proportions, into the solid state. The diastereoisomeric conformations are captured upon crystallization in a 1:1 molar ratio in the double-helical superstructure, whose handedness is dictated by the choice of the enantiomeric macrocyclic dimer. The interconversion of the two conformational diastereoisomers derived from each configurationally enantiomeric macrocycle was investigated in CD3SOCD3 solution by variable-temperature 1H NMR spectroscopy (VT NMR) and circular dichroism (VT CD). The merging of the resonances for the protons corresponding to the two diastereoisomers at a range of coalescence temperatures in the VT NMR spectra and occurrence of the isosbestic points in the VT CD spectra indicate that the two diastereoisomers are interconverting slowly in solution on the 1H NMR time scale but rapidly on the laboratory time scale. To the best of our knowledge, the self-assembly of such solid-state superstructures from two conformational diastereoisomers of a homochiral macrocycle is a rare, if not unique, occurrence.

AB - The reactivity of a CoI-H2 complex was extended toward the semihydrogenation of internal alkynes. Under ambient temperatures and moderate pressures of H2, a broad scope of alkynes were semihydrogenated using a CoI-N2 precatalyst, resulting in the formation of trans-alkene products. Furthermore, mechanistic studies using 1H, 2H, and para-hydrogen induced polarization (PHIP) transfer NMR spectroscopy revealed cis-hydrogenation of the alkyne occurs first. The Co mediated alkene isomerization afforded the E-selective products from a broad group of alkynes with good yields and E/Z selectivity.

AB - The atmospheric double barrier discharge (DBD) plasma technology is a promising tool in food industry as an alternative to traditional food preservation methods. However, the effect of the reactive chemical species generated during the treatment on the qualitative and quantitative content of bioactive compounds in food is still little studied, as well as there are no data concerning potential deleterious effects of DBD treated foods on human cells. We measured antioxidants content and antioxidant capacity of DBD-treated minimally processed Pink Lady(r) apples in comparison with untreated matched samples. Moreover, we compared the effects of polyphenols extracts obtained from DBD-treated apples on cell viability, reactive oxygen species production and phase II enzyme activation. The results show that the plasma treatment causes a slight reduction of antioxidant content and antioxidant capacity. Noteworthy, apple treated polyphenols extracts do not reduce cell viability and do not suppress the beneficial physiological cell response to oxidative stress.

AB - A weakly fluorescent Pt-bridged dyad composed of zinc(II) porphyrin (Zn; donor) and free base (Fb; acceptor) has been designed and exhibits an ultrafast singlet energy transfer between porphyrins. The use of larger atoms within the central linker significantly increases the MO coupling between the two chromophores and inherently the electronic communication. PMID- 27709920 TI - Key residues involved in the interaction between Cydia pomonella pheromone binding protein 1 (CpomPBP1) and Codlemone. AB - Codlemone exhibited high affinity to CpomPBP1, studying their binding mode can provide insights into the rational design of active semiochemicals. Our findings suggested that residues including Phe12, Phe36, Trp37, Ile52, Ile 94, Ala115 and Phe118 were favorable to the binding of Codlemone to CpomPBP1, whereas residues providing unfavorable contributions like Ser56 were negative to the binding. Van der waals energy and electrostatic energy, mainly derived from the sidechains of favorable residues, contributed most in the formation and stability keeping of CpomPBP1-Codlemone complex. Of the residues involved in the interaction between CpomPBP1 and Codlemone, Phe12 and Trp37, whose mutation into Ala caused significant decrease of CpomPBP1 binding ability, were two key residues in determining the binding affinity of Codlemone to CpomPBP1. This study shed lights on discovering novel active semiochemicals as well as facilitating chemical modification of lead semiochemicals.

AB - Understanding the fate of enteric viruses in water is vital for protection of water quality. However, the decay of enteric viruses is not well characterized, and its uncertainty has not been examined yet. In this study, the decay of coliphages, an indicator for enteric viruses, was investigated in situ under both sunlit and shaded conditions as well as in summer and winter. The decay rates of coliphages and their uncertainties were analyzed using a Bayesian approach. The results from the summer experiments revealed that the decay rates of somatic coliphages were significantly higher in sunlight (1.29 +/- 0.06 day-1) than in shade (0.96 +/- 0.04 day-1), but the decay rates of male-specific (F+) coliphages were not significantly different between sunlight (1.09 +/- 0.09 day-1) and shaded treatments (1.11 +/- 0.08 day-1). The decay rates of both F+ coliphages (0.25 +/- 0.02 day-1) and somatic coliphages (0.12 +/- 0.01 day-1) in winter were considerably lower than those in summer. Temperature and chlorophyll a (chla) concentration varied significantly (p < 0.001) between the two seasons, suggesting that these parameters might be important contributors to the seasonal variation of coliphage decay. Additionally, the Bayesian approach provided full distributions of decay rates and reduced the uncertainty, offering useful information for comparing decay rates under different conditions.

AB - The enantioselective synthesis of 4-fluoroisochromanones via chiral aryl iodide catalyzed fluorolactonization is reported. This methodology uses HF*pyridine as a nucleophilic fluoride source with a peracid stoichiometric oxidant, and provides access to lactones containing fluorine-bearing stereogenic centers in high enantio- and diastereoselectivity. The regioselectivity observed in these lactonization reactions is complementary to that obtained with established asymmetric electrophilic fluorination protocols. PMID- 27709923 TI - Nonstoichiometric Adduct Approach for High-Efficiency Perovskite Solar Cells. AB - Since the groundbreaking report on a solid-state perovskite solar cell employing a methylammonium lead iodide-sensitized mesoporous TiO2 film and an organic hole conducting layer in 2012 by our group, the swift surge of perovskite photovoltaics opens a new paradigm in solar-cell research. As a result, ca. 1300 peer-reviewed research articles were published in 2015. In this Inorganic Chemistry Forum on Halide Perovskite, the researches with highlights of work on perovskite solar cells in my laboratory are reviewed. We have developed a size controllable two-step spin-coating method and found that minimal nonradiative recombination in perovskite crystals could lead to high photovoltaic performance. A Lewis acid based adduct method and self-formed grain boundary process were developed for high-efficiency devices with reproducibility. A power conversion efficiency of 20.4% was achieved via grain boundary engineering based on a nonstoichiometric adduct approach. The incorporation of cesium in a formamidinium lead iodide perovskite was found to show better photostability and moisture stability. A reduction in the dimensionality from a three-dimensitonal nanocrystal to a one-dimensional nanowire led to a hypsochromic shift of absorption and fluorescence. To enhance the charge-carrier transport and light harvesting efficiency, a nanoarchitecture of oxide layers was proposed. PMID- 27709924 TI - Torsional Constraints of DNA Substrates Impact Cas9 Cleavage. AB - To examine the effect of the torsional constraints imposed on DNA substrates on Cas9 cleavage, we prepared con-strained DNA substrates using a DNA origami frame. By fixing the dsDNA at the connectors of the DNA frame, we created four different dsDNA substrates containing torsion-ally constrained or relaxed strands. We quantified the cleav-age of constrained and relaxed substrates by Cas9 with quantitative PCR. Moreover, we observed the Cas9/sgRNA complex bound to the DNA substrates and characterized the dissociation of the complex with high-speed AFM. The results revealed that the constrained non-target strand re-duced the cleavage efficiency of Cas9 drastically, whereas torsional constraints on the target strand had little effect on the cleavage. The present study suggests that highly ordered and constrained DNA structures could be obstacles for Cas9 and additionally provides insights in Cas9 dissociation at a single molecule level. PMID- 27709926 TI - Exploring the Chemical Reactivity between Carbon Dioxide and Three Transition Metals (Au, Pt, and Re) at High-Pressure, High-Temperature Conditions. AB - The role of carbon dioxide, CO2, as oxidizing agent at high pressures and temperatures is evaluated by studying its chemical reactivity with three transition metals: Au, Pt, and Re. We report systematic X-ray diffraction measurements up to 48 GPa and 2400 K using synchrotron radiation and laser heating diamond-anvil cells. No evidence of reaction was found in Au and Pt samples in this pressure-temperature range. In the Re + CO2 system, however, a strongly-driven redox reaction occurs at P > 8 GPa and T > 1500 K, and orthorhombic beta-ReO2 is formed. This rhenium oxide phase is stable at least up to 48 GPa and 2400 K and was recovered at ambient conditions. Raman spectroscopy data confirm graphite as a reaction product. Ab-initio total-energy structural and compressibility data of the beta-ReO2 phase shows an excellent agreement with experiments, altogether accurately confirming CO2 reduction P-T conditions in the presence of rhenium metal and the beta-ReO2 equation of state. PMID- 27709925 TI - Single Molecule Nanospectroscopy Visualizes Proton-Transfer Processes within a Zeolite Crystal. AB - Visualizing proton-transfer processes at the nanoscale is essential for understanding the reactivity of zeolite-based catalyst materials. In this work, the Bronsted-acid-catalyzed oligomerization of styrene derivatives was used for the first time as a single molecule probe reaction to study the reactivity of individual zeolite H-ZSM-5 crystals in different zeolite framework, reactant and solvent environments. This was accomplished via the formation of distinct dimeric and trimeric fluorescent carbocations, characterized by their different photostability, as detected by single molecule fluorescence microscopy. The oligomerization kinetics turned out to be very sensitive to the reaction conditions and the presence of the local structural defects in zeolite H-ZSM-5 crystals. The remarkably photostable trimeric carbocations were found to be formed predominantly near defect-rich crystalline regions. This spectroscopic marker offers clear prospects for nanoscale quality control of zeolite-based materials. Interestingly, replacing n-heptane with 1-butanol as a solvent led to a reactivity decrease of several orders and shorter survival times of fluorescent products due to the strong chemisorption of 1-butanol onto the Bronsted acid sites. A similar effect was achieved by changing the electrophilic character of the para-substituent of the styrene moiety. Based on the measured turnover rates we have established a quantitative, single turnover approach to evaluate substituent and solvent effects on the reactivity of individual zeolite H-ZSM-5 crystals. PMID- 27709927 TI - Realizing High Figure of Merit in Phase-Separated Polycrystalline Sn1-xPbxSe. AB - Solid-state thermoelectric technology, interconverting heat to electrical energy, offers a promising solution for relaxing global energy problems. A high dimensionless figure of merit ZT is desirable for high-efficiency thermoelectric power generation. To date, thermoelectric materials research has focused on increasing the material's ZT. Here we first fabricated phase-separated Sn1-xPbxSe materials by hydrothermal synthesis. We demonstrate that the simultaneous optimization of the power factor and significant reduction in thermal conductivity can be achieved in the phase-separated Sn1-xPbxSe material. The introduction of the PbSe phase contributes to improvement of the electrical conductivity and power factor of the SnSe phase. Meanwhile, nanoscale precipitates and mesoscale grains define all-scale hierarchical architectures to scattering phonons, leading to low lattice thermal conductivity. These two favorable factors lead to remarkably high thermoelectric performance with ZT ~ 1.7 at 873 K in polycrystalline SnSe + 1% PbSe along the pressing direction, which is a record-high ZT for SnSe polycrystals. These findings highlight the prospects of realizing highly effective solid-state thermoelectric devices. PMID- 27709928 TI - Stereoretentive Deuteration of alpha-Chiral Amines with D2O. AB - We present the direct and stereoretentive deuteration of primary amines using Ru bMepi (bMepi = 1,3-(6'-methyl-2'-pyridylimino)isoindolate) complexes and D2O. High deuterium incorporation occurs at the alpha-carbon (70-99%). For alpha chiral amines, complete retention of stereochemistry is achieved when using an electron-deficient Ru catalyst. The retention of enantiomeric purity is attributed to a high binding affinity of an imine intermediate with ruthenium, as well as to a fast H/D exchange relative to ligand dissociation. PMID- 27709929 TI - Analysis of Mycotoxins in Beer Using a Portable Nanostructured Imaging Surface Plasmon Resonance Biosensor. AB - A competitive inhibition immunoassay is described for the mycotoxins deoxynivalenol (DON) and ochratoxin A (OTA) in beer using a portable nanostructured imaging surface plasmon resonance (iSPR) biosensor, also referred to as imaging nanoplasmonics. The toxins were directly and covalently immobilized on a 3-dimensional carboxymethylated dextran (CMD) layer on a nanostructured iSPR chip. The assay is based on competition between the immobilized mycotoxins and free mycotoxins in the solution for binding to specific antibodies. The chip surface was regenerated after each cycle, and the combination of CMD and direct immobilization of toxins allowed the chips to be used for more than 450 cycles. The limits of detection (LODs) in beer were 17 ng/mL for DON and 7 ng/mL for OTA (or 0.09 ng/mL after 75 times enrichment). These LODs allowed detection of even less than 10% depletion of the tolerable daily intake of DON and OTA by beer. Significant cross-reactivity of anti-DON was observed toward DON-3-glucoside and 3-acetyl-DON, while no cross-reactivity was seen for 15-acetyl-DON. A preliminary in-house validation with 20 different batches of beer showed that both toxins can be detected at the considered theoretical safe level for beer. The assay can be used for in-field or at-line detection of DON in beer and also in barley without preconcentration, while OTA in beer requires an additional enrichment step, thus making the latter in its present form less suitable for field applications. PMID- 27709930 TI - A Least-Squares Commutator in the Iterative Subspace Method for Accelerating Self Consistent Field Convergence. AB - A least-squares commutator in the iterative subspace (LCIIS) approach is explored for accelerating self-consistent field (SCF) calculations. LCIIS is similar to direct inversion of the iterative subspace (DIIS) methods in that the next iterate of the density matrix is obtained as a linear combination of past iterates. However, whereas DIIS methods find the linear combination by minimizing a sum of error vectors, LCIIS minimizes the Frobenius norm of the commutator between the density matrix and the Fock matrix. This minimization leads to a quartic problem that can be solved iteratively through a constrained Newton's method. The relationship between LCIIS and DIIS is discussed. Numerical experiments suggest that LCIIS leads to faster convergence than other SCF convergence accelerating methods in a statistically significant sense, and in a number of cases LCIIS leads to stable SCF solutions that are not found by other methods. The computational cost involved in solving the quartic minimization problem is small compared to the typical cost of SCF iterations and the approach is easily integrated into existing codes. LCIIS can therefore serve as a powerful addition to SCF convergence accelerating methods in computational quantum chemistry packages. PMID- 27709931 TI - The Effect of Economic Growth, Urbanization, and Industrialization on Fine Particulate Matter (PM2.5) Concentrations in China. AB - Rapid economic growth, industrialization, and urbanization in China have led to extremely severe air pollution that causes increasing negative effects on human health, visibility, and climate change. However, the influence mechanisms of these anthropogenic factors on fine particulate matter (PM2.5) concentrations are poorly understood. In this study, we combined panel data and econometric methods to investigate the main anthropogenic factors that contribute to increasing PM2.5 concentrations in China at the prefecture level from 1999 to 2011. The results showed that PM2.5 concentrations and three anthropogenic factors were cointegrated. The panel Fully Modified Least Squares and panel Granger causality test results indicated that economic growth, industrialization, and urbanization increased PM2.5 concentrations in the long run. The results implied that if China persists in its current development pattern, economic growth, industrialization and urbanization will inevitably lead to increased PM2.5 emissions in the long term. Industrialization was the principal factor that affected PM2.5 concentrations for the total panel, the industry-oriented panel and the service oriented panel. PM2.5 concentrations can be reduced at the cost of short-term economic growth and industrialization. However, reducing the urbanization level is not an efficient way to decrease PM2.5 pollutions in the short term. The findings also suggest that a rapid reduction of PM2.5 concentrations relying solely on adjusting these anthropogenic factors is difficult in a short-term for the heavily PM2.5-polluted panel. Moreover, the Chinese government will have to seek much broader policies that favor a decoupling of these coupling relationships.

AB - Six polyoxo-titanium clusters (PTCs) with varying nuclearities containing Ti-N bonds and heteronuclearity, namely, [Ti6(MU3-O)2(MU2-O)2(O3P-Phen)2(OiPr)10(1 hbta)2] (PTC-37), Ti8(MU3-O)2(MU2-O)2(O3P-Phen)2(OiPr)16(adn)2(NO3)2] (PTC-38), [Ti4(MU3-O)(MU2-O)(MU2-OiPr)2(OiPr)4(O3P-Phen)3(1,10-phn)](HOiPr) (PTC-39), [Ti4(MU3-O)(MU2-OiPr)3(OiPr)5(O3P-Phen)3(Im)] (PTC-40), [Ti4(MU3-O)(MU2 OiPr)3(OiPr)5(O3P-Phen)3(Im)][Ti3M(MU3-O)(MU2-OiPr)3(OiPr)3(O3P-Phen)3(Im)] (M = Co for PTC-41 and M = Zn for PTC-42; O3P-Phen = phenyl phosphonate, 1-hbta = 1 hydroxy benzotriazolate, adn = adenine, 1,10-phn = 1,10-phenanthroline, Im = imidazolate, and OiPr = isopropoxide) were prepared as crystalline samples and structurally characterized. Simultaneous doping of nitrogen and transition metal heteroatoms into the Ti-O clusters created complex chemical environments in the resulting hybrid materials. Thus, photocatalytic methylene blue degradation studies were performed to understand structure-property relationships in these Ti cluster-based materials. The complex chemical environment created in these novel molecular clusters had proved to exhibit ligand-dependent photocatalytic activities under normal sunlight. Adenine-functionalized PTC-38 presented moderate activities, while other PTCs all show rapid dye degradation.

PMID- 27709934 TI - Fluorescent Base Analogue Reveals T-HgII-T Base Pairs Have High Kinetic Stabilities That Perturb DNA Metabolism. AB - The thymidine analogue DMAT was used for the first fluorescence-based study of direct, site-specific metal binding reactions involving unmodified nucleobases in duplex DNA. The fluorescence properties of DMAT-A base pairs were highly sensitive to mercury binding reactions at T-T mismatches located at an adjacent site or one base pair away. This allowed for precise determination of the local kinetic and thermodynamic parameters of T-HgII-T binding reactions. The on- and off-rates of HgII were surprisingly slow, with association rate constants (kon) ~ 104-105 M-1 s-1, and dissociation rate constants (koff) ~ 10-4-10-3 s-1; giving equilibrium dissociation constants (Kd) = 8-50 nM. In contrast, duplexes lacking a T-T mismatch exhibited local, nonspecific HgII binding affinities in the range of Kd = 0.2-2.0 MUM, depending on the buffer conditions. The exceptionally high kinetic stabilities of T-HgII-T metallo-base pairs (half-lives = 0.3-1.3 h) perturbed dynamic processes including DNA strand displacement and primer extension by DNA polymerases that resulted in premature chain termination of DNA synthesis. In addition to providing the first detailed kinetic and thermodynamic parameters of site-specific T-HgII-T binding reactions in duplex DNA, these results demonstrate that T-HgII-T base pairs have a high potential to disrupt DNA metabolism in vivo.

PMID- 27709935 TI - Conserved Mechanism of Conformational Stability and Dynamics in G-Protein-Coupled Receptors. AB - G-protein-coupled receptors (GPCRs) are transmembrane receptors involved in diverse biological functions. Despite the diversity in their amino acid sequences, class A GPCRs exhibit a conserved structural topology and possibly a common mechanism of receptor activation. To understand how this high sequence diversity translates to a conserved functional mechanism, we have compared the dynamic behavior of eight class A GPCRs comprised of six biogenic amine receptors, adenosine A2A, and the peptide receptor protease-activated receptor 1. Starting from the crystal structures of the inactive state of these receptors bound to inverse agonists or antagonists, we have performed multiple all-atom MD simulations adding up to several microseconds of simulation. We elucidated the similarities and differences in the dynamic behavior and the conformational ensembles sampled by these eight class A GPCRs. Among the six biogenic amine receptors studied here, beta2-adrenergic receptor shows the highest level of fluctuation in the sixth and seventh transmembrane helices, possibly explaining its high basal activity. In contrast, the muscarinic acetylcholine receptors show the lowest fluctuations as well as tight packing and low hydration of the transmembrane domain. All eight GPCRs show several conserved allosteric communication pipelines from the residues in the agonist binding site with the G protein interface. Positions of the residues along these pipelines that serve as major hubs of allosteric communication are conserved in their respective structures. These findings have important implications in understanding the dynamics and allosteric mechanism of communication in class A GPCRs and hence are useful for designing conformation-specific drugs.

AB - Three QS-21-based vaccine adjuvant candidates with a terminal-functionalized side chain incorporated in the west wing trisaccharide have been synthesized. The terminal polar functional group serves to increase the solubility of these analogues in water. Two of the synthetic analogues have been shown to have adjuvant activity comparable to that of GPI-0100. The stand-alone adjuvant activity of the new synthetic analogues again confirmed that it is a feasible way to develop new saponin-based vaccine adjuvants through derivatizing at the west wing branched trisaccharide domain. Inclusion of an additional polar functional group such as a carboxyl group (as in 3x) or a monosaccharide (as in 4x and 5x) is sufficient to increase the water solubility of the corresponding synthetic analogues to a level comparable to that of GPI-0100 and suitable for immunological studies and clinical application. The structure of the incorporated side chain has a significant impact on the adjuvant activity in terms of the magnitude and nature of the host's responses.

AB - Additions of alkyl- or arylthiols to 7-vinyl-7-deaza-2'-deoxyadenosine gave a series of 7-[2-(alkyl- or arylsulfanyl)ethyl]-7-deaza-2'-deoxyadenosines in 45 85% yields. The nucleosides were converted to 5'-O-mono-(dASRMP) or triphosphates (dASRTP) by phosphorylation. The modified triphosphates were also prepared by thiol addition to 7-vinyl-7-deaza-dATP. The triphosphates dASRTP were good substrates for DNA polymerases useful in the enzymatic synthesis of base-modified oligonucleotides (ONs) or DNA containing flexibly linked hydrophobic substituents in the major groove. Primer extension was used for the synthesis of ONs with one or several modifications, PCR was used for the synthesis of heavily modified DNA, whereas terminal deoxynucleotidyl transferase was used for a single-nucleotide labeling of the 3'-end. PMID- 27709939 TI - Assessing Ion-Water Interactions in the AMOEBA Force Field Using Energy Decomposition Analysis of Electronic Structure Calculations. AB - AMOEBA is a molecular mechanics force field that addresses some of the shortcomings of a fixed partial charge model, by including permanent atomic point multipoles through quadrupoles, as well as many-body polarization through the use of point inducible dipoles. In this work, we investigate how well AMOEBA formulates its non-bonded interactions, and how it implicitly incorporates quantum mechanical effects such as charge penetration (CP) and charge transfer (CT), for water-water and water-ion interactions. We find that AMOEBA's total interaction energies, as a function of distance and over angular scans for the water dimer and for a range of water-monovalent cations, agree well with an advanced density functional theory (DFT) model, whereas the water-halides and water-divalent cations show significant disagreement with the DFT result, especially in the compressed region when the two fragments overlap. We use a second-generation energy decomposition analysis (EDA) scheme based on absolutely localized molecular orbitals (ALMOs) to show that in the best cases AMOEBA relies on cancellation of errors by softening of the van der Waals (vdW) wall to balance permanent electrostatics that are too unfavorable, thereby compensating for the missing CP effect. CT, as another important stabilizing effect not explicitly taken into account in AMOEBA, is also found to be incorporated by the softened vdW interaction. For the water-halides and water-divalent cations, this compensatory approach is not as well executed by AMOEBA over all distances and angles, wherein permanent electrostatics remains too unfavorable and polarization is overdamped in the former while overestimated in the latter. We conclude that the DFT-based EDA approach can help refine a next-generation AMOEBA model that either realizes a better cancellation of errors for problematic cases like those illustrated here, or serves to guide the parametrization of explicit functional forms for short-range contributions from CP and/or CT.

AB - The rate constant for the reaction of di-tert-butyl malonate (DTBM) with chlorine atoms in gas-phase was measured using cyclohexane and pentane as references. The measurements lead to a value of (1.5 ? 0.1) x 10-10 cm3 molecule-1 s-1. The subsequent photo-oxidation mechanism of DTBM in the absence and presence of nitrogen dioxide was investigated. The main carbonated products identified in the first case were acetone, formic acid, carbon monoxide, and carbon dioxide. The addition of nitrogen dioxide lead besides to the formation of (CH3)3CC(O)OONO2 and (CH3)3CONO2. The proposed photo-oxidation mechanism was supported both experimentally and by computational calculations. The results reveal that the (CH3)3COC(O)CH2C(O)OC(CH3)2O* radical formed reacts according to two competitive reactions: decomposition to yield acetone and (CH3)3COC(O)CH2C(O)O* radical (55 +/- 2) %, and migration of the H-atom of the methylene group to the terminal oxygen atom (40 +/- 3) %.

AB - Scanning tunneling microscopy (STM) and spectroscopy probe the local density of states of single molecules electrically insulated from the substrate. The experimental images, although usually interpreted in terms of single-particle molecular orbitals, are associated with quasiparticle wave functions dressed by the whole electron-electron interaction. Here we propose an ab initio approach based on quantum Monte Carlo to calculate the quasiparticle wave functions of molecules. Through the comparison between Monte Carlo wave functions and their uncorrelated Hartree-Fock counterparts we visualize the electronic correlation embedded in the simulated STM images, highlighting the many-body features that might be observed.

AB - We report on the design, synthesis, and properties of innovative, planar, pi conjugated compounds in which a thiophene ring is fused with the skeleton of the naturally occurring dye isatin. The synthesis is achieved in high yields making use of an intramolecular direct arylation reaction as the key step, making the overall process potentially scalable. The synthetic sequence has been demonstrated also for an isatin bearing fluorine substituents on the aromatic ring. NMR and X-ray studies demonstrate the crosstalk occurring between the fused, coplanar, and conjugated moieties, making these novel dyes with a donor acceptor character. Cyclic voltammetry and UV-vis studies confirm very interesting HOMO-LUMO levels and energy gaps for the new compounds.

AB - A novel series of tetrahydroprotoberberine derivatives (THPBs) were designed, synthesized, and evaluated as selective alpha1A-adrenergic receptors (AR) antagonists for the treatment of benign prostatic hyperplasia. On the basis of the pharmacophore model of the marketed drug silodosin, THPBs were modified by introducing an indole segment into their core scaffolds. In calcium assays, 7 out of 32 compounds displayed excellent antagonistic activities against alpha1A-ARs, with IC50 less than 250 nM. Among them, compound (S)-27 had the most potent biological activity; its IC50 toward alpha1A-AR was 12.8 +/- 2.2 nM, which is 781 and 20 times more selective than that toward alpha1B- and alpha1D-AR, respectively. In the functional assay using isolated rat tissues, compound (S)-27 inhibited norepinephrine-induced urethra smooth muscle contraction potently (IC50 = 0.5 +/- 0.3 nM), without inhibiting the aortic contraction (IC50 > 1000 nM), displaying a better tissue selectivity than the marketed drug silodosin. Additional results of preliminary safety studies (acute toxicity and hERG inhibition) and pharmacokinetics studies indicated the potential druggability for compound (S)-27 which is a promising lead for the development of selective alpha1A-AR antagonists for the treatment of BPH.

PMID- 27709948 TI - Structures and Acidity Constants of Silver-Sulfide Complexes in Hydrothermal Fluids: A First Principles Molecular Dynamics Study. AB - In order to quantify the speciation and structures of silver-sulfide complexes in aqueous solutions, we have carried out systematic first principles molecular dynamics (FPMD) simulations at three temperatures (25 degrees C, 200 degrees C, and 300 degrees C). It is found that mono-sulfide (i.e., Ag(HS)) and di-sulfide species (i.e., Ag(HS)2-) are the major silver-sulfide species over a wide T-P range, while Ag(HS)32- can hold stably only at ambient temperatures and Ag(HS)43- does not exist even at the ambient conditions. Ag(H2S)+ has a tetrahedral structure up to 300 degrees C (i.e., Ag(H2S)(H2O)3+). Ag(H2S)2+ remains 4 coordinated to 200 degrees C (i.e., Ag(H2S)2(H2O)2+) but it transforms to 3 coordinate at 300 degrees C (i.e., Ag(H2S)2(H2O)+). All of the other mono- and di sulfide species (Ag(HS)(H2O)0, Ag(HS)(OH)-, Ag(HS)(H2S)0, Ag(HS)2- and AgS(HS)2-) have two-fold linear structures. For their solvation structures, the H2S ligands donate weak H-bonds to water O; the HS- ligands accept weak H-bonds from water H; the dangling S2- form strong H-bonds with H of water molecules and the OH- ligands can form strong H-bonds as donors and weak H-bonds as acceptors. We further calculated the acidity constants (i.e. pKas) of Ag(H2S)+ and Ag(H2S)2+ complexes using FPMD based vertical energy gap method. Based on the calculated pKas, the mono- and di-sulfide species distributions versus pH have been derived. We found that for mono-sulfide species, Ag(HS)(H2O)0 is the major species in near neutral pH, while Ag(H2S)(H2O)3+ and Ag(HS)(OH)- exist in the acid and alkaline pH range at T<=200 degrees C, respectively. At 300 degrees C, both Ag(HS)(OH)- and Ag(HS)(H2O)0 are dominant in the neutral pH range, and Ag(H2S)(H2O)2+ only exists in acidic solutions. For di-sulfide species, Ag(HS)2- is dominative in near neutral pH condition at the three temperatures; Ag(HS)(H2S)0 stays in mild acidic pH range only at 25 degrees C; AgS(HS)2- and Ag(H2S)2(H2O)2+ (Ag(H2S)2(H2O)+ at 300 degrees C) are trivial at the three conditions. The results of structures and acidity constants provide quantitative and microscopic basis for understanding the behavior of silver complexes in hydrothermal fluids. PMID- 27709949 TI - Systematic and Automated Development of Quantum Mechanically Derived Force Fields: The Challenging Case of Halogenated Hydrocarbons. AB - A robust and automated protocol for the derivation of sound force field parameters, suitable for condensed-phase classical simulations, is here tested and validated on several halogenated hydrocarbons, a class of compounds for which standard force fields have often been reported to deliver rather inaccurate performances. The major strength of the proposed protocol is that all of the parameters are derived only from first principles because all of the information required is retrieved from quantum mechanical data, purposely computed for the investigated molecule. This a priori parametrization is carried out separately for the intra- and intermolecular contributions to the force fields, respectively exploiting the Joyce and Picky programs, previously developed in our group. To avoid high computational costs, all quantum mechanical calculations were performed exploiting the density functional theory. Because the choice of the functional is known to be crucial for the description of the intermolecular interactions, a specific procedure is proposed, which allows for a reliable benchmark of different functionals against higher-level data. The intramolecular and intermolecular contribution are eventually joined together, and the resulting quantum mechanically derived force field is thereafter employed in lengthy molecular dynamics simulations to compute several thermodynamic properties that characterize the resulting bulk phase. The accuracy of the proposed parametrization protocol is finally validated by comparing the computed macroscopic observables with the available experimental counterparts. It is found that, on average, the proposed approach is capable of yielding a consistent description of the investigated set, often outperforming the literature standard force fields, or at least delivering results of similar accuracy.

AB - Ligand paramagnetic NMR (pNMR) chemical shifts of the 5f1 complexes UO2(CO3)35- and NpO2(CO3)34-, and of the 5f2 complexes PuO2(CO3)34- and (C5H5)3UCH3 are investigated by wave function theory calculations, using a recently developed sum over-states approach within complete active space and restricted active space paradigm including spin-orbit (SO) coupling [J. Phys. Chem. Lett. 2015, 20, 2183 2188]. The experimental 13C pNMR shifts of the actinyl tris-carbonate complexes are well reproduced by the calculations. The results are rationalized by visualizing natural spin orbitals (NSOs) and spin-magnetizations generated from the SO wave functions, in comparison with scalar relativistic spin densities. The analysis reveals a complex balance between spin-polarization, spin and orbital magnetization delocalization, and spin-compensation effects due to SO coupling. This balance creates the magnetization due to the electron paramagnetism around the nucleus of interest, and therefore the pNMR effects. The calculated proton pNMR shifts of the (C5H5)3UCH3 complex are also in good agreement with experimental data. Because of the nonmagnetic ground state of (C5H5)3UCH3, the 1H pNMR shifts arise mainly from the magnetic coupling contributions between the ground state and low-energy excited states belonging to the 5f manifold, along with the thermal population of degenerate excited states at ambient temperatures. PMID- 27709951 TI - Minimal Self-Immolative Probe for Multimodal Fluoride Detection. AB - Two single-molecule, self-immolative fluoride probes, namely tert butyldimethylsilyl-protected 2- and 4-difluoromethylphenol, are described. Compared to similar systems previously described, the probes are characterized by a simpler structure and straightforward, two-step preparation. Nevertheless, they allow the detection of fluoride ions at micromolar concentration by the naked eye, UV-vis absorption, and fluorescence. A detailed investigation of the self immolative reaction reveals that the rate-limiting step is the release of the first fluoride ion from the difluoromethylphenolate intermediate. Moreover, the mutual position of the difluoromethyl- and tert-butyldimethylsilyl-protected residues has a relevant effect on the reactivity. Likely, a CF2H-O hydrogen bond in the 2-isomer increases the reactivity of the silyl ether toward hydrolytic cleavage but also stabilizes the phenolate intermediate, slowing the release of fluoride ions. PMID- 27709952 TI - Modulation of the Excited-State Dynamics of 2,2'-Bipyridine-3,3'-diol in Crown Ethers: A Possible Way To Control the Morphology of a Glycine Fibril through Fluorescence Lifetime Imaging Microscopy. AB - In this article, we have investigated the modulation of excited-state intramolecular double proton transfer (ESIDPT) dynamics of 2,2'-bipyridine-3,3' diol (BP(OH)2) in two crown ethers (CEs), namely, 18-Crown-6 (18C6) and 15-Crown 5 (15C5). From steady-state UV-visible measurements, we have shown that there is no significant interaction between the dienol tautomeric form of BP(OH)2 and two CEs. However, in the presence of CEs, an additional emission band (~415 nm) is generated along with the diketo tautomer band (~465 nm). In time-resolved analysis, we have observed the generation of ~260 ps rise component in the presence of 18C6. Therefore, by combining the results of steady-state and time resolved emissions, we have proposed that the water-assisted ESIDPT route of BP(OH)2 generates a hydronium ion (H3O+) in the excited state. 18C6 binds nicely to this H3O+ ion. As a result, retarded ESIDPT dynamics is observed in 18C6. However, as 15C5 cannot bind H3O+ properly, no rise component is found. With the addition of potassium chloride (KCl), the contribution of the rise component decreases due to unavailability of free 18C6 cavity to capture the H3O+ ion generated in the excited state. Addition of calcium chloride (CaCl2) leads to complete removal of the rise component due to the inhibition of the water assisted ESIDPT route. From wavelength-dependent behavior, we have observed that the rise component is present only at 465 nm in 18C6. We have also shown that the fibrillar morphology of glycine can be successfully probed through fluorescence lifetime imaging microscopy using BP(OH)2 as an imaging agent. Modulation of fibrillar morphology has been found in the presence of two CEs. The interaction of glycine fiber with CEs can be explained by lifetime distribution analysis.

AB - The thermally induced hydration transition of surface-grafted poly(N-isopropyl acrylamide) (PNIPAAm) brushes was probed by surface plasmon resonance spectroscopy (SPR) and contact angle measurements. Data are presented for a PNIPAAm brush film with a dry thickness of ~50 nm that was synthesized by atom radical transfer polymerization on the surface of a self-assembled monolayer on gold. SPR measurements were taken as a function of temperature in two modes: the quasi-static mode, in which the sample was equilibrated at each temperature for ~15 min prior to measurement, and the real-time mode, in which SPR reflectivity data were collected as the sample was heated and cooled at ~4.5 degrees C/min. Both types of measurement indicate that the hydration transition for the PNIPAAm brush occurs over a broad range of temperatures (~10-40 degrees C). This result is in accordance with theoretical predictions that have suggested that polymer brush structures on planar surfaces do not exhibit true critical solubility transitions. Contact angle measurements revealed a discontinuity in the surface wettability at a temperature (~32 degrees C) that corresponds to the dilute aqueous critical solution temperature. Taken together, these results suggest that the polymer segments in the outermost region of the brush remain highly solvated until the dilute solution lower critical solution temperature (~32 degrees ), while densely packed, less solvated segments within the brush layer undergo dehydration and collapse over a broad range of temperatures.

AB - Despite their different chemistries, novel energy-storage systems, e.g., Li-air, Li-S, all-solid-state Li batteries, etc., face one critical challenge of forming a conductive and stable interface between Li metal and a solid electrolyte. An accurate understanding of the formation mechanism and the exact structure and chemistry of the rarely existing benign interfaces, such as the Li-cubic-Li7 3xAlxLa3Zr2O12 (c-LLZO) interface, is crucial for enabling the use of Li metal anodes. Due to spatial confinement and structural and chemical complications, current investigations are largely limited to theoretical calculations. Here, through an in situ formation of Li-c-LLZO interfaces inside an aberration corrected scanning transmission electron microscope, we successfully reveal the interfacial chemical and structural progression. Upon contact with Li metal, the LLZO surface is reduced, which is accompanied by the simultaneous implantation of Li+, resulting in a tetragonal-like LLZO interphase that stabilizes at an extremely small thickness of around five unit cells. This interphase effectively prevented further interfacial reactions without compromising the ionic conductivity. Although the cubic-to-tetragonal transition is typically undesired during LLZO synthesis, the similar structural change was found to be the likely key to the observed benign interface. These insights provide a new perspective for designing Li-solid electrolyte interfaces that can enable the use of Li metal anodes in next-generation batteries. PMID- 27709955 TI - Novel effects of compressed CO2 molecules on structural ordering and charge transport in conjugated poly(3-hexylthiophene) thin films. AB - We report the effects of compressed CO2 molecules as a novel plasticization agent for poly(3-hexylthiophene) (P3HT) conjugated polymer thin films. In-situ neutron reflectivity experiment demonstrated the excess sorption of CO2 molecules in the P3HT thin films (about 40 nm in thickness) at low pressure (P = 8.2 MPa) under the isothermal condition of T = 36 degrees C, which is far below the polymer bulk melting point. The results evidenced that these CO2 molecules accelerated the crystallization process of the polymer on the basis of ex-situ grazing incidence X-ray diffraction measurements after drying the films via rapid depressurization to atmospheric pressure: not only the out-of-plane lamellar ordering of the backbone chains but also intra-plane pi-pi stacking of the side chains were significantly improved, when compared to those in the control P3HT films subjected to conventional thermal annealing (at T = 170 degrees C). Electrical measurements elucidated that the CO2-annealed P3HT thin films exhibited enhanced charge carrier mobility along with decreased background charge carrier concentration and trap density compared to those in the thermally annealed counterpart. This is attributed to the CO2-induced increase in polymer chain mobility that can drive the detrapping of molecular oxygen and healing of conformational defects in the polymer thin film. Given the universality of the excess sorption of CO2 regardless of the type of polymers, the present findings suggest that the CO2 annealing near the critical point can be useful as a robust processing strategy for improving structural and electrical characteristics of other semiconducting conjugated polymers and related systems such as polymer: fullerene bulk heterojunction films.

AB - Alkali-activated materials (AAMs) are currently being pursued as viable alternatives to conventional ordinary Portland cement because of their lower carbon footprint and established mechanical performance. However, our understanding of the mesoscale morphology (~1 to 100 nm) of AAMs and related amorphous aluminosilicate gels, including the development of the three dimensional aluminosilicate network and nanoscale porosity, is severely limited. This study investigates the structural changes that occur during the formation of AAM gels at the mesoscale by utilizing a coarse-grained Monte Carlo (CGMC) modeling technique that exploits density functional theory calculations. The model is capable of simulating the reaction of an aluminosilicate particle in a highly alkaline solution (sodium hydroxide or sodium silicate). Two precursor morphologies have been investigated (layered alumina and silica sheets mimicking metakaolin and spherical aluminosilicate particles reminiscent of coal-derived fly ash) to determine if the precursor morphology has an impact on the structural evolution of the resulting alkali-activated aluminosilicate gel. The CGMC model can capture the three major stages of the alkali-activation process-dissolution, polycondensation, and reorganization-revealing that the dissolved silicate and aluminate species, ranging from monomers to nanoprecipitates (100s of monomers in size), exist in the pore solution of the hardened gel. The model also reveals that the silica concentration of the activating solution controls the extent of dissolution of the precursor particle. From the analysis of the aluminosilicate cluster size distributions, the mechanisms of AAM gel growth have been elucidated, revealing that Ostwald ripening occurs in systems containing free silica at the start of the reaction. On the other hand, growth of the hydroxide activated systems (metakaolin and fly ash) occurs via the formation of intermediate-sized clusters in addition to continual growth of the largest particle. The simulation results indicate that the nature of the gel growth is not influenced by the precursor particle morphology.

AB - Previous statistical studies on the mechanical properties of chemical-vapor deposited (CVD) suspended graphene membranes have been performed by means of measuring individual devices or with techniques that affect the material. Here, we present a colorimetry technique as a parallel, noninvasive, and affordable way of characterizing suspended graphene devices. We exploit Newton's rings interference patterns to study the deformation of a double-layer graphene drum 13.2 MUm in diameter when a pressure step is applied. By studying the time evolution of the deformation, we find that filling the drum cavity with air is 2 5 times slower than when it is purged. PMID- 27709958 TI - Early-Evaporation of Microlayer for Boiling Heat Transfer Enhancement. AB - For over five decades, enhancement in pool boiling heat transfer has been achieved by altering the surface wetting, wickability, roughness, nucleation site density and providing separate liquid/vapor pathways. In this work, a new enhancement mechanism based on the early-evaporation of the microlayer is discovered and validated. The microlayer is a thin liquid film present at the base of a vapor bubble. Presence of micro-ridges on the silicon-dioxide surface partitions the microlayer and disconnects it from bulk liquid causing it to evaporate sooner, thus leading to increase in bubble growth rate, heat transfer, departure frequency and critical heat flux (CHF). Compared to a plain surface, ~120% enhancement in CHF is obtained with only ~18% increase in surface area. A CHF enhancement map is developed based on ridge height and spacing, resulting in three regions of full, partial and no enhancement. The new mechanism is validated by comparing the growth rate of a laser created vapor bubble on ridge-structured surface and plain surface, and the corresponding prediction of CHF enhancement is found to be in good agreement with experimental boiling data. This discovery opens up a new field of CHF enhancement and can be coupled with existing techniques to further push the limits of boiling heat transfer.

AB - Positron emission tomography (PET) imaging has transformed diagnostic nuclear medicine and become an essential strategy in cancer management. With the expected growth of this molecular imaging modality, there is a recognized need for new PET probes to address the clinical challenges in the early diagnosis and staging of various types of cancers. In this endeavor, the prospect of using 64Cu in the form of simple Cu2+ ions as PET probe is not only a cost-effective proposition but also seems poised to broaden the palette of molecular imaging probes in the foreseeable future. The usefulness of 64Cu2+ ions as PET probe is based on the fact that Cu is an essential element that plays an important role in cell proliferation and angiogenesis. Over the past few years, there has been continuous flow of evidences based on studies in animal models on the uptake of 64Cu2+ ions in different types of tumors, including, hepatoma, colorectal cancer, prostate cancer, lung cancer, breast cancer, head and neck cancer, fibrosarcoma, melanoma, glioblastoma, and ovarian cancer. The widespread preclinical success of 64Cu2+ ions as PET probe has recently resulted in translation of this radiotracer to clinical settings for noninvasive imaging and staging of prostate cancer in human patients. In this concise review, we have focused on the latest developments in PET imaging of cancer in preclinical and clinical settings using 64Cu2+ ion as a probe and discussed the challenges and opportunities for future development.

AB - Five new heterometallic UO22+-Co2+ coordination polymers have been obtained by hydrothermal reactions of uranyl nitrate and metallic cobalt with aromatic polycarboxylic acids. Single-crystal X-ray diffraction reveals the formation of four 3D frameworks with the mellitate (noted mel) ligand and one 2D network with the isophthalate (noted iso) ligand. The compounds [(UO2(H2O))2Co(H2O)4(mel)].4H2O (1), [UO2Co(H2O)4(H2mel)].2H2O (2), and [(UO2(H2O))2Co(H2O)4(mel)] (4) consist of 3D frameworks built up from the connection of mellitate ligands and mononuclear metallic centers. These three compounds exhibit two types of geometry for the uranyl cation: pentagonal bipyramidal environment for 1 and 4, and hexagonal bipyramidal environment for 2. Using the mellitate ligand, the uranyl dinuclear unit is isolated in the compound [(UO2)2(OH)2(Co(H2O)4)2(mel)].2H2O (3). Due to their 2D framework and the presence of uncoordinated cobalt(II) cations, the compound [(UO2)(iso)3][Co(H2O)6].3(H2O) (5) is drastically different than the previous one. The thermal behavior of compounds 1, 2, and 3 has been studied by thermogravimetric analysis, X-ray thermodiffraction, and in situ infrared. By heating, the dehydration of compounds 1 and 2 promotes two structural transitions (1 -> 1' and 2 -> 2'). The crystal structures of [(UO2(H2O))2Co(H2O)2(mel)] (1') and [(UO2)Co(H2mel)] (2') were determined by single-crystal X-ray diffraction; each of them presents a heterometallic interaction between uranyl bond and the Co(II) center. Due to the rarely reported coordination environment for the cobalt center in compound 2' (square pyramidal configuration), the magnetic properties and EPR characterizations of the compounds 2 and 2' were also investigated. PMID- 27709965 TI - Elastocaloric Effect in Carbon Nanotubes and Graphene. AB - Carbon nanotubes are famous for their many extraordinary properties. We use a thermodynamical approach, experimental data from the literature, and atomistic simulations to reveal one more remarkable property of the carbon nanotubes that has so far been overlooked. Namely, we predict the existence of very large elastocaloric effect that can reach up to 30 K under moderate loads. Potentially even larger values could be achieved under extreme loads, putting carbon nanotubes in the forefront of caloric materials. Other remarkable features of the elastocaloric effect in carbon nanotubes include linearity of elastocaloric temperature change in applied force (compressive or stretching), very weak dependence on the temperature, and an absence of hysteresis. Such features are extremely desirable for practical applications in cooling devices. Moreover, a similarly large elastocaloric effect is predicted for the graphene. The prediction of a large elastocaloric effect in carbon nanotubes and graphene sets forward an unconventional strategy of targeting materials with moderate caloric responses but the ability to withstand very large loads.

AB - Male Eurasian jays have been found to adjust the type of food they share with their female partner after seeing her eat 1 type of food to satiety. One interpretation of this behavior is that the male encoded the female's decreased desire for the food she was sated on, and adjusted his behavior accordingly. However, in these studies, the male's actions were scored by experimenters who knew on which food the female was sated. Thus, it is possible that the experimenters' expectations (subconsciously) affected their behavior during tests that, in turn, inadvertently could have influenced the males' actions. Here, we repeated the original test with an experimenter who was blind to the food on which the female was sated. This procedure yielded the same results as the original studies: The male shared food with the female that was in line with her current desire. Thus, our results rule out the possibility that the Eurasian jay males' actions in the food sharing task could be explained by the effects of an experimenter expectancy bias.

AB - Development of a pH stat to properly control solution pH in biomolecular simulations has been a long-standing goal in the community. Toward this goal recent years have witnessed the emergence of the so-called constant pH molecular dynamics methods. However, the accuracy and generality of these methods have been hampered by the use of implicit-solvent models or truncation-based electrostatic schemes. Here we report the implementation of the particle mesh Ewald (PME) scheme into the all-atom continuous constant pH molecular dynamics (CpHMD) method, enabling CpHMD to be performed with a standard MD engine at a fractional added computational cost. We demonstrate the performance using pH replica exchange CpHMD simulations with titratable water for a stringent test set of proteins, HP36, BBL, HEWL, and SNase. With the sampling time of 10 ns per replica, most pKa's are converged, yielding the average absolute and root-mean square deviations of 0.61 and 0.77, respectively, from experiment. Linear regression of the calculated vs experimental pKa shifts gives a correlation coefficient of 0.79, a slope of 1, and an intercept near 0. Analysis reveals inadequate sampling of structure relaxation accompanying a protonation-state switch as a major source of the remaining errors, which are reduced as simulation prolongs. These data suggest PME-based CpHMD can be used as a general tool for pH controlled simulations of macromolecular systems in various environments, enabling atomic insights into pH-dependent phenomena involving not only soluble proteins but also transmembrane proteins, nucleic acids, surfactants, and polysaccharides. PMID- 27709969 TI - Anticipated ambiguity prolongs the present: Evidence of a return trip effect. AB - Every event that can occupy a span of time can also warp how long that duration feels. No shortage of factors configures such duration estimates, yet they remain largely confined to events experienced in the present moment. Might future events similarly impact duration? The present investigation leverages a phenomenological return trip effect, which documents subjectively longer outbound journeys relative to identical inbound journeys, to inform this question. Through this lens, the focal event (that which will transpire at the destination) can be decoupled from the focal duration (the span of time between the present moment and arrival at that destination). Four studies document a consistent effect in which ambiguity awaiting at a future event (occurring at the destination) expands the subjective magnitude of present durations (the travel time to the destination). Duration judgments thus appear sensitive to an increasingly broad scope of factors, informing models of temporal cognition.

AB - In this study, we examined associations between qualities of families' social contexts and experiences of coparenting. In a sample of 92 adoptive families, we assessed perceived social support among 23 lesbian, 28 gay, and 41 heterosexual adoptive parent families and its association with parents' perceptions of their coparenting alliances. Results showed that parents in same- and other-sex couples reported receiving similar amounts of social support from family, friends, and significant others. Perceived social support was positively associated with stronger coparenting alliance among all family types. Perceived support from family members explained more variance in parenting alliance than did support from friends or significant others. These findings add to knowledge about fundamental family processes and enhance understanding of parenthood among lesbian and gay adoptive couples.

AB - Recent work has highlighted that process-outcome relationships are likely to vary depending on the client, yet there is little direct evidence regarding specific intervention effects in individual clients. This study attempted to address the hypothesis that some clients reveal more than others regarding the impact of specific interventions. Intensive case study analyses were applied to 2 clients with principal major depressive disorder and comorbid anxiety disorders receiving transdiagnostic psychotherapy. Clients completed a battery of symptom and psychological assessments of mindfulness, cognitive reappraisal use, and emotion avoidance on many occasions throughout treatment. Time series analyses were applied to symptom and change construct data. Results included: (a) significant decreases in depression, anxiety, and emotion avoidance from baseline to posttreatment were observed, as well as significant increases in mindfulness and reappraisal; and (b) in one case, intervention strategies exerted little influence on changes in key variables; in the other, emotion exposure strategies had the strongest influence on increases in mindfulness and present-focused awareness strategies had the strongest influence on reductions in emotion avoidance. Even when different clients appear to similarly benefit from the same treatment, specific intervention effects on putative change factors may be more prevalent for some clients and less prevalent for others. Regular assessment is needed to determine if a client requires an alternative set of specific intervention strategies.

(2016). AB - : Reports an error in "Distant but relative: Similarities and differences in gender role beliefs among African American and Vietnamese American women" by Jasmine A. Abrams, Sarah J. Javier, Morgan L. Maxwell, Faye Z. Belgrave and Anh Bao Nguyen (Cultural Diversity and Ethnic Minority Psychology, 2016[Apr], Vol 22[2], 256-267). In the article, the name of author Anh Bao Nguyen was misspelled as Boa Anh Nguyen. The online version of this article has been corrected. (The following abstract of the original article appeared in record 2015-18954-001.) Objectives: Research attempting to identify similarities or disentangle differences in ethnic minority gender role beliefs has been largely absent in the literature, and a gap remains for qualitative examinations of such phenomena. The purpose of this study is to fill this gap in the literature by providing a qualitative examination of the differences and similarities of gender role beliefs among African American and Vietnamese American women. METHODS: Thematic analyses were conducted with data gathered from 8 focus groups with 44 African American women (mean age = 44 years) and 4 focus Groups 47 Vietnamese American women (mean age = 42 years). Women were diverse in generational, religious, and educational backgrounds. RESULTS: Two similar primary themes emerged: (a) women's roles as chief caretakers and (b) women's responsibility to fulfill multiple roles. There were also similar experiences of a need to convey strength and be self-sacrificial. Two distinct differences that emerged from the focus groups were beliefs about interpersonal interactions and perceptions of societal expectations. CONCLUSIONS: This study demonstrates that the conceptualization of gender role beliefs, although at times similar, diverges among culturally different groups. To account for these and other culturally nuanced differences, measures of gender role beliefs should be culturally tailored and culturally specific. However, researchers have largely excluded ethnic minority women in the development of the most widely used measures of gender role beliefs in the U.S. The inclusion of diverse women in research will help prevent pitfalls of conflating and ignoring intragroup differences among different groups of marginalized women.

AB - OBJECTIVE: Individuals' lay beliefs about mental health problems and attitudes toward mental health care are thought to be influenced by the cultural background of these individuals. In the current study, we investigated differences between immigrant Dutch and native Dutch parents and adolescents in lay beliefs about emotional problems and attitudes toward mental health care. Additionally, among immigrant Dutch parents, we examined the associations between acculturation orientations and lay beliefs about emotional problems as well as attitudes toward mental health care. METHOD: In total, 349 pairs of parents and their adolescent children participated in our study (95 native Dutch, 85 Surinamese-Dutch, 87 Turkish-Dutch, 82 Moroccan-Dutch). A vignette was used to examine participants' lay beliefs. RESULTS: Immigrant Dutch and native Dutch parents differed in their lay beliefs and attitudes toward mental health care, whereas hardly any differences were revealed among their children. Turkish-Dutch and Moroccan-Dutch parents showed more passive and fewer active solutions to emotional problems compared to native Dutch parents. Additionally, Moroccan-Dutch and Surinamese Dutch parents reported greater fear of mental health care compared to native Dutch parents. Furthermore, the results showed that immigrant Dutch parents who were more strongly oriented toward the Dutch culture reported less fear of mental health care. CONCLUSION: Our results showed clear differences in lay beliefs and attitudes toward mental health care between immigrant Dutch and native Dutch parents but not between their children. Substantial differences were also found between parents from different immigrant Dutch populations as well as within the population of immigrant Dutch parents.

AB - The study examined the performance of maximum likelihood (ML) and multiple imputation (MI) procedures for missing data in longitudinal research when fitting latent growth models. A Monte Carlo simulation study was conducted with conditions of small sample size, intermittent missing data, and nonnormality. The results indicated that ML tended to display slightly smaller degrees of bias than MI across missing completely at random (MCAR) and missing at random (MAR) conditions. Although specification of prior information in the MI imputation posterior (I-P) phase influenced the performance of MI, especially with nonnormal small samples and missing not at random (MNAR), the impact of this tight specification was not dramatic. Several corrected ML test statistics showed proper rejections rates across research designs, whereas posterior predictive p values for MI methods were more likely to be influenced by distribution shape and yielded higher rejection rates in MCAR and MAR than in MNAR. In conclusion, ML appears to be preferable to MI in research conditions with small missing samples and multivariate nonnormality whether or not strong prior information for the I-P phase of MI analysis is available.

AB - Older adults are usually more easily distracted by task-irrelevant stimuli than younger ones. In addition, there is evidence that it takes them more time to overcome a distracting event. Here, the distracting effect of irregular switches in speaker location was studied in 22 younger and 22 older adults in a speech perception task. The participants responded to target words that were presented either from a frequent location (standard trials) or a rare location (deviant trials). Behavioral performance measures, event-related brain potentials (ERPs), and EEG synchronization (intertrial coherence [ITC]) were analyzed. Behavioral performance was not only decreased in deviant trials, but also in subsequent standard trials, indicating an effect of so-called postdeviance distraction. The negative impact of the distracting event (i.e., the switch in speaker location) on the processing of subsequent (standard) trials was more pronounced in the older versus younger group. The EEG analyses revealed a decreased N2 amplitude and increased latencies in P2 and P3a in the older group, suggesting a reduced and delayed attentional control. Moreover, there were age-related changes in late (200-450 ms) theta ITCs: While the ITC of the young remained constant in trials following a deviant, the ITC of the old decreased, suggesting a decline in processing of stimuli following (task-irrelevant) switches in speaker location. This could contribute to age-related deficits in speech comprehension in spatially variable listening situations. (PsycINFO Database Record PMID- 27709976 TI - Boredom begs to differ: Differentiation from other negative emotions. AB - Boredom research is booming. Nonetheless, a comprehensive understanding of boredom in relation to other negative emotions is lacking. This ambiguity impedes accurate interpretation of boredom's causes and consequences. To gain more insights into boredom, we examined in detail how it differs from a range of other negative experiences, namely sadness, anger, frustration, fear, disgust, depression, guilt, shame, regret, and disappointment. Our research indicates that the appraisals associated with boredom distinguish it clearly from other negative emotions; conceptually (Study 1), in terms of state experiences (Study 2), and in terms of individual differences in these experiences (Study 3). Our findings suggest that boredom is mild in negative valence, low in arousal, is associated with low perceived challenge and low perceived meaningfulness, and has low relevance to moral judgment and behavior. Boredom also involves low attention given to situations and tasks, and the lack of perceived meaningfulness and attention associated with boredom emerged as particularly distinctive characteristics. The findings underscore the importance of carefully discriminating boredom from other emotions in experimental induction, psychometric assessment, and conceptual discussion. (PsycINFO Database Record PMID- 27709977 TI - On the relationship between positive and negative affect: Their correlation and their co-occurrence. AB - Understanding the nature of emotional experience requires understanding the relationship between positive and negative affect. Two particularly important aspects of that relationship are the extent to which positive and negative affect are correlated with one another and the extent to which they co-occur. Some researchers have assumed that weak negative correlations imply greater co occurrence (i.e., more mixed emotions) than do strong negative correlations, but others have noted that correlations may imply very little about co-occurrence. We investigated the relationship between the correlation between positive and negative affect and co-occurrence. Participants in each of 2 samples provided moment-to-moment happiness and sadness ratings as they watched an evocative film and listened to music. Results indicated (a) that 4 measures of the correlation between positive and negative affect were quite highly related to 1 another; (b) that the strength of the correlation between measures of mixed emotions varied considerably; (c) that correlational measures were generally (but not always) weakly correlated with mixed emotion measures; and (d) that bittersweet stimuli consistently led to elevations in mixed emotion measures but did not consistently weaken the correlation between positive and negative affect. Results highlight that the correlation between positive and negative affect and their co-occurrence are distinct aspects of the relationship between positive and negative affect. Such insight helps clarify the implications of existing work on age-related and cultural differences in emotional experience and sets the stage for greater understanding of the experience of mixed emotions. (PsycINFO Database Record PMID- 27709978 TI - An Internet-based virtual reality intervention for enhancing self-esteem in women with disabilities: Results of a feasibility study. AB - PURPOSE: To examine the feasibility of an online self-esteem enhancement group program for women with disabilities. METHOD: A sample of 19 racially and ethnically diverse, community-living women with physical disabilities, 22 to 61 years old, participated in a 7-session interactive group intervention (extending Hughes et al., 2004) in the 3-D, immersive, virtual environment of SecondLife.com, using avatars with voice and text communication. Baseline and postintervention questionnaires were administered online. Criteria for determining feasibility were (a) enrollment, (b) engagement, (c) acceptability, and (d) improvement on measures of self-esteem, depression, self-efficacy, and social support. RESULTS: We attained our enrollment goal and engagement exceeded expectations. Acceptability was positive; participants gave "helpful" and "enjoyable" ratings of 3.21 and 3.27, respectively, (mean on a 1 to 4 Likert scale, where 4 = high) to 5 intervention components-session materials, group sharing and discussion, relaxation exercises, action planning, and group excursions. Significant increases from baseline to postintervention were found on the Rosenberg Self-Esteem Scale (p = .02; Cohen's d = .60) and the Center for Epidemiologic Studies Depression Scale-10 (p = .005; Cohen's d = .74), with a trend toward significance on the Generalized Self-Efficacy Scale (p = .08; Cohen's d = .42). The intervention did not significantly affect the measure of social support. IMPLICATIONS: An intervention to enhance self-esteem may have a corollary benefit on depressive symptomatology. Offering psycho-educational, small group interventions using online virtual worlds shows promise for circumventing disability-related and environmental barriers to accessing mental health services experienced by women with mobility limitations, and should undergo further development and testing. (PsycINFO Database Record PMID- 27709979 TI - Risk factors that predict future onset of each DSM-5 eating disorder: Predictive specificity in high-risk adolescent females. AB - Because no single report has examined risk factors that predict future onset each type of eating disorder and core symptom dimensions that crosscut disorders, we addressed these aims to advance knowledge regarding risk factor specificity. Data from 3 prevention trials that targeted young women with body dissatisfaction (N = 1,272; Mage = 18.5, SD = 4.2) and collected annual diagnostic interview data over 3-year follow-up were combined to identify predictors of subthreshold/threshold anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD). Negative affect and functional impairment predicted onset of all eating disorders. Thin-ideal internalization, body dissatisfaction, dieting, overeating, and mental health care predicted onset of subthreshold/threshold BN, BED, and PD; positive thinness expectations, denial of cost of pursuing the thin ideal, and fasting predicted onset of 2 of these 3 disorders. Similar risk factors predicted core eating disorder symptom onset. Low BMI and dieting specifically predicted onset of subthreshold/threshold AN or low BMI. Only a subset of factors showed unique predictive effects in multivariate models, likely due to moderate correlations between the risk factors (M r = .14). Results provide support for the theory that pursuit of the thin ideal and the resulting body dissatisfaction, dieting, and unhealthy weight control behaviors increase risk for binge/purge spectrum eating disorders, but suggest that youth who are inherently lean, rather than purposely pursuing the thin ideal, are at risk for AN. Impaired interpersonal functioning and negative affect are transdiagnostic risk factors, suggesting these factors should be targeted in prevention programs. (PsycINFO Database Record PMID- 27709981 TI - Deontological coherence: A framework for commonsense moral reasoning. AB - We review a broad range of work, primarily in cognitive and social psychology, that provides insight into the processes of moral judgment. In particular, we consider research on pragmatic reasoning about regulations and on coherence in decision making, both areas in which psychological theories have been guided by work in legal philosophy. Armed with these essential prerequisites, we sketch a psychological framework for how ordinary people make judgments about moral issues. Based on a literature review, we show how the framework of deontological coherence unifies findings in moral psychology that have often been explained in terms of a grab-bag of heuristics and biases. (PsycINFO Database Record PMID- 27709980 TI - Hyperfocusing of attention on goal-related information in schizophrenia: Evidence from electrophysiology. AB - Schizophrenia clearly involves impairments of attention, but the precise nature of these impairments has been difficult to determine. One possibility is that the deficit in attention is a secondary consequence of a deficit in goal maintenance. However, recent research suggests that people with schizophrenia (PSZ) actually focus attention more strongly on objects containing goal-relevant features. To test these competing hypotheses, we recorded event-related potentials (ERPs) from PSZ (N = 20) and healthy control subjects (HCS; N = 20) while they looked for a particular target color at fixation and tried to ignore lateral distractors that sometimes matched the target color (target-color distractors). Goal maintenance was made trivially easy by the continual presentation of a goal reminder. We found that HCS were able to successfully suppress target-color distractors (leading to a distractor positivity ERP component), whereas PSZ focused attention on these items (leading to an N2-posterior-contralateral ERP component). This suggests that, when maintaining a task set, PSZ engage in aberrant focusing of attention, or hyperfocusing, on goal-relevant features. (PsycINFO Database Record PMID- 27709983 TI - More than just beliefs: Experience and beliefs jointly contribute to volume effects on metacognitive judgments. AB - Experience-based cues, such as perceptual fluency, have long been thought to influence metacognitive judgments (Kelley & Jacoby, 1996; Koriat, 1997). Studies found that manipulations of perceptual fluency via changes in font and volume alter Judgments of Learning (JOLs) without influencing memory performance (Rhodes & Castel, 2008, 2009). Nonetheless, recent research (Mueller, Tauber, & Dunlosky, 2013; Mueller, Dunlosky, Tauber, & Rhodes, 2014, 2016) has challenged the notion that experience-based cues such as fluency are the primary basis for item-level JOLs, arguing instead that preexisting beliefs about these manipulations are responsible for these effects. For the first time, we compared global metacognitive judgments to item-level JOLs made during study to independently assess the contribution of beliefs and experience to volume-effects on JOLs. In 3 experiments, we found evidence for strong beliefs about volume-effects on memory, both before and after a study-test phase. However, these beliefs either did not account for the volume effect on JOLs (Experiment 3) or only partially accounted for the volume effect on JOLs (Experiments 1 and 2). Further, in Experiments 2 and 3 global performance estimates (before and after study) did not differ with respect to the volume dose whereas item-level JOLs generally varied with dose strength. Taken together, our findings suggest that both beliefs and experience based cues contribute independently to the effects of volume on item-level JOLs, but that beliefs alone cannot fully account for the effects of volume on item level JOLs. (PsycINFO Database Record PMID- 27709982 TI - Drawing the line between constituent structure and coherence relations in visual narratives. AB - Theories of visual narrative understanding have often focused on the changes in meaning across a sequence, like shifts in characters, spatial location, and causation, as cues for breaks in the structure of a discourse. In contrast, the theory of visual narrative grammar posits that hierarchic "grammatical" structures operate at the discourse level using categorical roles for images, which may or may not co-occur with shifts in coherence. We therefore examined the relationship between narrative structure and coherence shifts in the segmentation of visual narrative sequences using a "segmentation task" where participants drew lines between images in order to divide them into subepisodes. We used regressions to analyze the influence of the expected constituent structure boundary, narrative categories, and semantic coherence relationships on the segmentation of visual narrative sequences. Narrative categories were a stronger predictor of segmentation than linear coherence relationships between panels, though both influenced participants' divisions. Altogether, these results support the theory that meaningful sequential images use a narrative grammar that extends above and beyond linear semantic shifts between discourse units. (PsycINFO Database Record PMID- 27709984 TI - Adaptation and fallibility in experts' judgments of novice performers. AB - Competition judges are often selected for their expertise, under the belief that a high level of performance expertise should enable accurate judgments of the competitors. Contrary to this assumption, we find evidence that expertise can reduce judgment accuracy. Adaptation level theory proposes that discriminatory capacity decreases with greater distance from one's adaptation level. Because experts' learning has produced an adaptation level close to ideal performance standards, they may be less able to discriminate among lower-level competitors. As a result, expertise increases judgment accuracy of high-level competitions but decreases judgment accuracy of low-level competitions. Additionally, we demonstrate that, consistent with an adaptation level theory account of expert judgment, experts systematically give more critical ratings than intermediates or novices. In summary, this work demonstrates a systematic change in human perception that occurs as task learning increases. (PsycINFO Database Record PMID- 27709985 TI - Isolating component processes of posterror slowing with the psychological refractory period paradigm. AB - Posterror slowing (PES) refers to an increased response time following errors. While PES has traditionally been attributed to control adjustments, recent evidence suggested that PES reflects interference. The present study investigated the hypothesis that control and interference represent 2 components of PES that differ with respect to their time course and task-specificity. To this end, we investigated PES in a dual-task paradigm in which participants had to classify colors and tones that were separated by a variable stimulus onset asynchrony (SOA). Errors in the color task caused PES both in the tone task of the same trial and the color task of the subsequent trial. However, while the former effect disappeared with an increasing SOA, the latter effect was independent of SOA and lasted for several trials. This suggests that errors simultaneously induce task-unspecific, transient PES reflecting interference and task-specific, more long-lasting PES reflecting control adjustments. (PsycINFO Database Record PMID- 27709986 TI - Estradiol is associated with altered cognitive and physiological responses during fear conditioning and extinction in healthy and spider phobic women. AB - The first-line psychological treatment for anxiety disorders is exposure therapy, which can be modeled in the laboratory using fear extinction. In healthy women, estradiol levels predict return of fear following extinction, whereas low levels are associated with greater return of fear. Investigating whether estradiol is similarly associated with extinction in clinically anxious women may provide insight to mechanisms underlying symptom relapse following exposure therapy. In the present study, women with spider phobia and healthy women participated in a 2 day fear conditioning and extinction procedure during a period of high or low estradiol levels. Skin conductance responses, shock expectancy, and valence ratings were measured throughout. Women exhibited comparable decreases in physiological arousal from conditioning to the end of extinction training on Day 1. However, compared to women with high estradiol, and irrespective of clinical status, women with low estradiol exhibited significant return of physiological arousal at extinction recall on Day 2, despite accurate ratings regarding the likelihood of shock. Low estradiol women also reported heightened threat expectancy and physiological responding during presentation of safety cues. These results may point to novel means of enhancing exposure therapy in women by timing treatment delivery during periods of higher estradiol levels. (PsycINFO Database Record PMID- 27709987 TI - PDTRT special section: Current trends in borderline personality disorder research. AB - One of the enjoyable benefits of being an editor of a journal is the ability to develop special sections. It is evident simply from a perusal of a typical issue of Personality Disorders: Theory, Research, and Treatment (PDTRT) that a common focus of research is borderline personality disorder (BPD). BPD is among, if not the, most heavily researched personality disorder. It is only natural to have the first special section within my tenure as editor concern this personality disorder. Provided within this special section are review papers of current trends in BPD research by young (at least compared to me), leading, and innovative BPD researchers. (PsycINFO Database Record PMID- 27709989 TI - Borderline personality disorder and the emerging field of developmental neuroscience. AB - Over the past 2 decades there has been a dramatic shift in understanding of personality disorders, such as borderline personality disorder (BPD). What was historically viewed as an entrenched pattern of antagonistic, interpersonally dependent, and uncorrectable conduct is now seen as the outcome of complex-yet modifiable-developmental processes. The borderline label, which once inspired such harsh opprobrium in clinical communities that early diagnosis was considered taboo, is now increasingly applied to adolescents who are receiving effective treatment and desisting from a borderline trajectory. Research examining the developmental origins and early manifestations of BPD is increasing rapidly, making it an appropriate time to take stock of current developmental research and articulate an agenda for the future. We identify 4 challenges that continue to impede innovative research on borderline personality development: (a) inadequate attention to continuity and discontinuity across development, (b) medical and diagnostic systems that localize personality pathology within the individual, (c) the lingering belief that biological research is antithetical to contextual/interpersonal understandings of psychopathology (and vice versa), and (d) reluctance to reach across disciplinary and developmental boundaries to identify creative paradigms and foster innovative discovery. In order to overcome these challenges, we propose an approach to future research on adolescent borderline pathology that integrates developmental psychopathology, social and affective neuroscience, and personality theory perspectives. This intersection the developmental neuroscience of personality pathology-offers theoretical and methodological advantages over disciplinary isolation and is fertile ground for generating novel hypotheses on the development and prevention of BPD. (PsycINFO Database Record PMID- 27709988 TI - A systematic review of risk factors prospectively associated with borderline personality disorder: Taking stock and moving forward. AB - There is an urgent need to identify signs that harbinger onset of borderline personality disorder (BPD). Advancement in this area is required to refine developmental theories, discover etiological mechanisms, improve early detection, and achieve our ultimate goal of prevention. Though many studies have supported a wide range of factors that increase subsequent risk for BPD, this literature has yet to be critically evaluated, and there are no comprehensive reviews that examine and integrate these findings. To address this limitation, we conducted a systematic review to summarize and synthesize the current literature. Electronic databases were systematically searched for prospective, longitudinal studies that examined risk factors of subsequent BPD outcomes (features, symptoms, diagnosis), resulting in a total of 39 studies, reflecting 24 unique samples. Though increased risk for BPD was reliably attributed to multiple factors within social, family, maltreatment, and child domains, the most striking limitation of this research is its lack of disorder-specific findings. Additional limitations, including notable heterogeneity in sampling methodology, symptom assessment methodology, and developmental timing of assessments, are discussed in terms of how close we are to pinpointing who is most at risk and why in an attempt to provide a roadmap for future research. (PsycINFO Database Record PMID- 27709990 TI - Current trends in BPD research as indicative of a broader sea-change in psychiatric nosology. AB - The aim of the Special Section that this paper contributes to is to review current trends in borderline personality disorder (BPD) research. Three major trends were identified. First, there has been a marked increase in studies that attempt to locate BPD in the dimensional latent structure of psychopathology. Second, identifying the endophenotypic markers associated with BPD has become a focus of interest. Here, we focus on one endophenotype in the form of impaired self-other processing. Third, there has been an explosion of research into the developmental aspects of BPD specifically focused on uncovering complex Biology * Environment interactions in the development of BPD. This paper discusses how these trends (Dimensions, Biology, and Development) are challenging the nature and form of BPD as we know it, and may be indicative of a broader sea-change in psychiatric nosology. (PsycINFO Database Record PMID- 27709991 TI - The role of emotion dysregulation in the presence, associated difficulties, and treatment of borderline personality disorder. AB - Theory and research identify emotion dysregulation as one of the primary mechanisms underlying borderline personality disorder (BPD) and related pathology. Yet, despite the extensive research documenting an association between emotion dysregulation and BPD, many questions regarding the precise role of emotion dysregulation in the development and treatment of BPD and its associated difficulties remain unanswered. This paper reviews the extant literature on the role of emotion dysregulation in BPD and its associated difficulties, as well as the treatment of BPD-related pathology, and identifies important next steps for future research in this area. In particular, this review highlights the need for further research examining: (a) the dimensions of emotion dysregulation that are unique to BPD, (b) the role and nature of interpersonal (vs. intrapersonal) emotion regulation in BPD, (c) the role of emotion dysregulation in the physical (vs. mental) health problems associated with BPD, and (d) the role of emotion regulation in efficacious treatments for BPD. Such research has the potential to elucidate the precise emotion regulation deficits that are most relevant (and central) to BPD, the active ingredients and mechanisms of change in current efficacious treatments for BPD, and the most effective and efficient targets for integrative treatments for this population. (PsycINFO Database Record PMID- 27709992 TI - Leadership emergence over time in short-lived groups: Integrating expectations states theory with temporal person-perception and self-serving bias. AB - Research into leadership emergence typically focuses on the attributes of the emergent leader. By considering also the attributes of perceivers and the passage of time, we develop a more complete theory of leadership emergence in short-lived groups. Using expectation states theory as an overarching theoretical framework, and integrating it with the surface- and deep-level diversity literature and with theories of self-serving biases, we examine the predictors of leadership emergence in short timeframes. We conduct a field study in a military assessment boot camp (a pilot study, n = 60; and a main study, n = 89). We use cross sectional and longitudinal exponential random graph models to analyze data on participants' abilities and on their perceptions of who, in their respective groups, were "leaders." We find that the criteria by which people perceive leadership in others change over time, from easily noticeable attributes to covert leadership-relevant attributes, and that people also rely on leadership relevant attributes that they possess at high levels to inform their perceptions of leadership in others. The integration of expectation states theory, attribute salience over time and theories of self-serving bias is needed for a full understanding of leadership emergence in groups, because perceivers' own abilities are instrumental in shaping their perceptions of emergent leadership over time. Theoretical and practical implications are discussed. (PsycINFO Database Record PMID- 27709993 TI - Binding an event to its source at encoding improves children's source monitoring. AB - Children learn information from a variety of sources and often remember the content but forget the source. Whereas the majority of research has focused on retrieval mechanisms for such difficulties, the present investigation examines whether the way in which sources are encoded influences future source monitoring. In Study 1, 86 children aged 3 to 8 years participated in 2 photography sessions on different days. Children were randomly assigned to either the Difference condition (they were asked to pay attention to differences between the 2 events), the Memory control condition (asked to pay attention with no reference to differences), or the No-Instruction control (no special instructions were given). One week later, during a structured interview about the photography session, the 3- to 4-year-olds in the No-Instruction condition were less accurate and responded more often with 'do not know' than the 7- to 8-year-olds. However, the older children in the Difference condition made more source confusions than the younger children suggesting improved memory for content but not source. In Study 2, the Difference condition was replaced by a Difference-Tag condition where details were pointed out along with their source (i.e., tagging source to content). Ninety-four children aged 3 to 8 years participated. Children in the Difference-Tag condition made fewer source-monitoring errors than children in the Control condition. The results of these 2 studies together suggest that binding processes at encoding can lead to better source discrimination of experienced events at retrieval and may underlie the rapid development of source monitoring in this age range. (PsycINFO Database Record PMID- 27709994 TI - IQ at age 12 following a history of institutional care: Findings from the Bucharest Early Intervention Project. AB - Young children removed from institutions and placed into foster care or adoptive homes have been shown to experience significant gains in IQ relative to children who remain in institutions. Less is known about the long-term impact of severe early deprivation on development in late childhood. Data are presented from a follow-up of children at 12 years of age in the Bucharest Early Intervention Project, a randomized clinical trial of foster care for institutionally reared children. Of the original 136 children in the study, 107 were tested with the Wechsler Intelligence Scale for Children-IV. Results revealed continued benefit from the intervention through age 12, with 12-year-old children placed in foster care scoring significantly higher on full-scale IQ compared to their peers who received prolonged institutional care. Longitudinal IQ data revealed 2 IQ profiles from early to late childhood. Attachment security emerged as a significant predictor of a profile of stable, typical IQ scores over time. We demonstrate the continued importance of foster care intervention and the negative effects of severe, early psychosocial deprivation on IQ into late childhood. (PsycINFO Database Record PMID- 27709995 TI - Time-varying effects of family ethnic socialization on ethnic-racial identity development among Latino adolescents. AB - Previous research has established that family ethnic socialization messages promote ethnic-racial identity (ERI) development, yet it is unknown whether these effects remain constant throughout adolescence. The current study examined the time-varying effects of family ethnic socialization on ERI exploration and resolution among Latino adolescents (n = 323, Mage at T1 = 15.31, SDage = .76; 49.5% female). As adolescents progressed from middle to late adolescence, the relation between family ethnic socialization and exploration became stronger, while the relation between family ethnic socialization and resolution became weaker, with a significant difference between the magnitude of these associations emerging in late adolescence. The findings underscore the differential impact that family ethnic socialization messages can have on ERI developmental processes at different points in adolescence. In addition, the current study provides a useful illustration of how time-varying effects modeling can be used to examine how familial influences on youth development can change across developmental periods. (PsycINFO Database Record PMID- 27709997 TI - Maternal mind-mindedness and children's school readiness: A longitudinal study of developmental processes. AB - This study aimed to test a 5-wave sequential mediation model linking maternal mind-mindedness during infancy to children's school readiness in kindergarten through a serial mediation involving child language and effortful control in toddlerhood and the preschool years. Among a sample of 204 mother-child dyads, we assessed maternal mind-mindedness when children were aged 1 year, child expressive vocabulary at age 2, effortful control at ages 3 and 4, and finally cognitive school readiness in kindergarten. The results corroborated the model, suggesting that the prospective association between early mind-mindedness and later cognitive school readiness was entirely mediated by the proposed sequence of mediators, all of which were necessary to account for this longitudinal association. These findings suggest that the potential of parental mind mindedness to support children's cognitive development may have been underestimated, and that its putative positive influence may take the form of a developmental cascade unfolding during the preschool years and entailing the acquisition of basic skills that serve as building blocks for further learning and development. (PsycINFO Database Record PMID- 27709996 TI - The risks and rewards of sexual debut. AB - The sex-positive framework of sexual development hypothesizes that healthy sexual experiences can be developmentally appropriate and rewarding for adolescents despite the risks involved. Research has not examined whether risky behaviors and rewarding cognitions actually change with sexual debut at a normative or late age. This study measured the longitudinal impact of sexual debut using 7 waves of data from 88 male and 86 female adolescents from a western U.S. city who were in the 10th grade at the study's onset. We used piecewise growth curve analyses to compare behaviors and cognitions before and after first sexual intercourse for those whose debut was at a normative or late age. These analyses revealed that sexual debut was related to rewards, including increases in romantic appeal and sexual satisfaction. In addition, internalizing symptoms declined over time after sexual debut, and substance use grew at a slower rate after sexual debut. We also examined whether differences existed among those whose debut was at an early, normative, or late age. Linear growth curve analyses revealed early sexual debut was related to risks, such as greater substance use, more internalizing and externalizing symptoms, and lower global self-worth. Rewards associated with an early debut included greater romantic appeal, dating satisfaction (males only), and sexual satisfaction (males only). Although there are some inherent risks with sexual activity, the results suggest that sexual debut at a normative or late age is also associated with a decrease in some risks and an increase in rewards.

AB - Drawing from a relational developmental systems (RDS) perspective (Lerner, Agans, DeSouza, & Gasca, 2013) and data from 1,427 continuously partnered young adult and midlife mixed-sex couples over the first 5 years of the German Panel Analysis of Intimate Relationships and Family Dynamics (pairfam), this study examined the developmental course of supportive dyadic coping, or the frequency with which one provides practical and emotional support when his or her partner encounters stress. Latent change score (LCS) modeling results revealed that supportive dyadic coping gradually declined for both male and female partners, but there was significant diversity underlying these trajectories. Higher levels of supportive dyadic coping were associated with a more gradual decline in support provided by a partner. Among young adults, a more rapid decline in male partner supportive dyadic coping predicted a slower rate of decline in support from female partners. Finally, we considered possible bidirectional relations between contextual stressors and supportive dyadic coping trajectories. Providing higher levels of support predicted a more gradual decline in self-rated health for male partners. Having more children and experiencing economic pressure predicted steeper declines in supportive dyadic coping over time for both male and female partners. (PsycINFO Database Record PMID- 27710000 TI - "Because if you don't put the top on, it will spill": A longitudinal study of sibling teaching in early childhood. AB - Naturalistic dyadic sequences of teaching and learning involving older and younger siblings were investigated in 39 middle-class dyads over a 2-year period in early childhood. Siblings were observed during ongoing interactions in the home setting for 6 90-min sessions at both Time 1 (older sibling M age = 4.4 years; younger sibling M age = 2.4 years) and Time 2 (older sibling M age = 6.3 years; younger sibling M age = 4.4 years). Sequences of sibling-directed teaching (T1 n = 353; T2 n = 1,039) were identified from the observation transcripts and coded for teacher/learner roles, initiation of teaching, teaching strategies, and learner response. Older siblings were more likely to engage in teaching at both time points, but the proportion of younger sibling teaching increased significantly from T1 to T2, partially because older siblings requested teaching more often from their younger siblings at T2. Siblings' use of teaching strategies varied across time points, while both older and younger sibling learners generally accepted or complied with the teaching. A final set of analyses examined birth-order effects while controlling for age by comparing older sibling teachers at age 4 (T1) to younger sibling teachers at age 4 (T2). At T1 first-born older siblings (age 4) engaged in a wider range and more sophisticated teaching strategies than second-born younger siblings (age 4) at T2. Findings highlight the bidirectional nature of teacher-learner interactions and are discussed in light of recent theory and research indicating that the sibling relationship is a rich context for children's learning and development. (PsycINFO Database Record PMID- 27709999 TI - The development of self-regulation across early childhood. AB - The development of early childhood self-regulation is often considered an early life marker for later life successes. Yet little longitudinal research has evaluated whether there are different trajectories of self-regulation development across children. This study investigates the development of behavioral self regulation between the ages of 3 and 7 years, with a direct focus on possible heterogeneity in the developmental trajectories, and a set of potential indicators that distinguish unique behavioral self-regulation trajectories. Across 3 diverse samples, 1,386 children were assessed on behavioral self regulation from preschool through first grade. Results indicated that majority of children develop self-regulation rapidly during early childhood, and that children follow 3 distinct developmental patterns of growth. These 3 trajectories were distinguishable based on timing of rapid gains, as well as child gender, early language skills, and maternal education levels. Findings highlight early developmental differences in how self-regulation unfolds, with implications for offering individualized support across children. (PsycINFO Database Record PMID- 27710001 TI - Trauma, posttraumatic stress disorder symptoms, and dissociative experiences during men's intimate partner violence perpetration. AB - OBJECTIVE: Research with partner-violent men has found that a subset of this population reports dissociative experiences during their violence (e.g., inability to remember violence [despite admission that it had occurred]; flashbacks during violence). However, the literature examining this phenomenon has been primarily limited to clinical observations and case studies, and there is a need for more thorough empirical investigation regarding the prevalence and correlates of dissociative violence among individuals in intimate partner violence (IPV) intervention programs. The primary goals of this study were to provide descriptive information about the rates of endorsement of dissociative experiences during IPV perpetration and to examine their associations with trauma exposure and posttraumatic stress disorder (PTSD) symptoms. METHOD: Participants were 302 men presenting for services at a community-based IPV intervention program. All variables were assessed via self-report and clinician interview at program intake. RESULTS: Results indicated that 22.2% of participants reported 1 or more dissociative experiences during partner violence perpetration. Additionally, frequency of dissociative IPV perpetration showed significant positive correlations with the total number of potentially traumatic events (PTEs) reported and PTSD symptoms, with effect sizes in the small and medium ranges of magnitude, respectively. Finally, PTSD symptoms significantly mediated the relationship between total number of PTEs and dissociative IPV perpetration. CONCLUSIONS: Findings indicate a potentially meaningful relationship between trauma, PTSD symptoms, and dissociative experiences during IPV perpetration. Further qualitative and quantitative investigation is needed to better understand this phenomenon and how it can be addressed in IPV treatment. (PsycINFO Database Record PMID- 27710002 TI - Development of the Vicarious Resilience Scale (VRS): A measure of positive effects of working with trauma survivors. AB - OBJECTIVE: Attending to the potential impacts, both positive and negative, of clinical work with trauma survivors on professionals themselves is a crucial aspect of clinical training and supervision. Vicarious resilience refers to unique, positive effects that transform therapists in response to witnessing trauma survivors' resilience and recovery process. This study describes the development and exploratory factor analysis of the first instrument to assess vicarious resilience. METHOD: The Vicarious Resilience Scale (VRS) was developed and administered via electronic survey to 190 helping professionals from around the globe working with survivors of severe traumas, such as torture. RESULTS: Exploratory factor analysis yielded 7 factors: Changes in life goals and perspective, client-inspired hope, increased recognition of clients' spirituality as a therapeutic resource, increased capacity for resourcefulness, increased self awareness and self-care practices, increased consciousness about power and privilege relative to clients' social location, and increased capacity for remaining present while listening to trauma narratives. The Cronbach's alpha reliability of the VRS was .92 and, as hypothesized, the VRS was moderately and positively correlated with posttraumatic growth and compassion satisfaction, indicating convergent validity. The VRS was not significantly correlated with compassion fatigue (CF) or burnout, indicating discriminant validity and that vicarious resilience is a unique construct that is not merely "the opposite" of CF or burnout. CONCLUSION: The VRS possesses sound psychometric properties and can be utilized in supervision and training contexts and for self-assessment by professionals working with trauma survivors to aid the recognition and cultivation of vicarious resilience. (PsycINFO Database Record PMID- 27710003 TI - Feasibility and effectiveness of narrative exposure therapy and cognitive behavioral therapy in a context of ongoing violence in South Africa. AB - OBJECTIVE: In an observer-blinded intervention trial, we tested the reduction of posttraumatic stress symptoms, aggressive attitude, and behavior in young males living in a context of ongoing community and gang violence by means of (a) forensic offender rehabilitation narrative exposure therapy (FORNET), and (b) the cognitive-behavioral intervention "Thinking for a Change" (TFAC). A waiting list served as the control condition. METHOD: A total of 39 young men were included in the data analysis: 15 completed FORNET, 11 underwent cognitive-behavioral therapy (CBT), and 13 were on a waiting list for later treatment. The primary efficacy endpoints were the PTSD Symptom Scale-Interview (PSS-I) severity score, the Appetitive Aggression Scale (AAS) score, and the number of perpetrated violent event types 8 months (on average) after treatment. RESULTS: Only in the sample receiving FORNET were posttraumatic stress disorder (PTSD) scores significantly reduced at the first follow-up (Cohen's d = -0.97) and significantly different from those of the control group (Cohen's d = -1.03). The changes in scores for appetitive aggression and perpetrated events were not significant for any of the treatment conditions. CONCLUSIONS: The study shows that trauma-focused treatment can reduce the psychological symptoms of posttraumatic stress even for individuals living under unsafe conditions in low-income urban communities. However, achieving changes in violent behavior within a context of ongoing violence may require more than the treatment of trauma-related suffering, confrontation with one's offenses, or cognitive-behavioral interventions. (PsycINFO Database Record PMID- 27710004 TI - Complex trauma in childhood, a psychiatric diagnosis in adulthood: Making meaning of a double-edged phenomenon. AB - OBJECTIVE: No known research explores the double-edged phenomenon of childhood trauma/adult mental health consumer. Therefore, whether receiving a psychiatric diagnosis in light of childhood trauma supports or impedes psychological wellbeing in adult life, is unknown. METHOD: Interpretative phenomenological analysis (IPA) provided the methodological framework. Data were collected through the use of semistructured interviews. Analysis sought thematic representation from subjective interpretations of the experienced phenomenon: childhood trauma survivor/mental health consumer. RESULTS: Data revealed 1 superordinate theme, Childhood Betrayal, Identity, and Worthiness, that overarched 5 subordinate themes a) legacies, (b) the label, (c) putting the jigsaw together, (d) stigma, and (e) better than good enough self. Legacies of doubt that perpetuated "not good enough" delayed the development of an adult identity of worthiness in these participants. Importantly, the right diagnosis separated self as worthy-adult from self as traumatized child and facilitated positive change for breaking harmful cycles, self-valuing, and increased empathy, wisdom, and patience. CONCLUSIONS: Findings inform future research and therapeutic practice in regards to adult help seeking behaviors in light of childhood trauma, often postponed through fear of stigma associated with mental health diagnoses and services. Similarly, findings suggest that ameliorating wellbeing may be dependent on a therapeutic relationship in which accuracy or right fit of diagnosis provides a conduit for the client to disengage from self-blame, unworthiness, and "not good enough." (PsycINFO Database Record PMID- 27710005 TI - The role of substance use coping in the relation between childhood sexual abuse and depression among methamphetamine users in South Africa. AB - OBJECTIVE: Childhood sexual abuse (CSA) is a critical global health issue associated with poor psychosocial outcomes. Individuals with CSA histories are at risk for drug use, which is a growing problem in the Western Cape of South Africa. The present study of methamphetamine users in this region examined whether substance use coping, a contextually relevant type of avoidance-based coping, mediates the relation between CSA and depressive symptoms. METHOD: Participants included 161 men and 108 women seeking treatment for methamphetamine use. Participants completed a computer-assisted survey and a face-to-face interview with clinic staff to evaluate history of CSA, current substance use severity and coping, and current depressive symptoms. RESULTS: Nearly a third of participants reported a history of CSA, and the average methamphetamine use severity score exceeded the threshold of high risk. A history of CSA was significantly associated with higher substance use coping and more depression symptoms. Substance use coping was a significant mediator of the association between CSA and depression symptoms. CONCLUSIONS: In this study of high-risk methamphetamine users, substance use coping emerged as a common means of managing stress, especially for those with a history of CSA, which was further linked to depressive symptoms. These findings underscore the potential benefit of integrating coping interventions and mental health treatment into substance abuse treatment programs, particularly for those with a history of childhood abuse and violence. (PsycINFO Database Record PMID- 27710006 TI - A randomized clinical trial of a postdeployment parenting intervention for service members and their families with very young children. AB - OBJECTIVE: Parenting through the deployment cycle presents unique stressors for military families. To date, few evidence-based and military-specific parenting programs are available to support parenting through cycles of deployment separation and reintegration, especially for National Guard/Reserve members. The purpose of this research was to test the efficacy of a parenting program developed specifically to support military families during reintegration. METHOD: Within 1 year of returning from deployment to Afghanistan or Iraq, 115 service members with very young children were randomly assigned to receive either the Strong Families Strong Forces Parenting Program at baseline or after a 12-week waiting period. Using a home-based modality, service members, at-home parents, and their young child were assessed at baseline, 3 months posttreatment/wait period, and 6 months from baseline. RESULTS: Service member parents in Strong Families evidenced greater reductions in parenting stress and mental health distress relative to those in the waitlist comparison group. Service members with more posttraumatic stress symptoms reported higher levels of perceived parental efficacy in the intervention group than service members in the comparison group. Intervention also resulted in enhanced parental reflective capacity, including increased curiosity and interest in the young child among those in the intervention group relative to comparison. CONCLUSION: Service member parents and their spouses demonstrated high interest in participating in a postdeployment parenting program targeting families with very young children. Findings point to the feasibility, appeal, and efficacy of Strong Families in this initial trial and suggest promise for implementation in broader military and community service systems. (PsycINFO Database Record PMID- 27710007 TI - Intergenerational transmission of captivity trauma and posttraumatic stress symptoms: A twenty three-year longitudinal triadic study. AB - OBJECTIVES: The aversive, long-term toll of war captivity and fathers' combat induced posttraumatic stress disorder symptoms (PTSS) on adult offspring's mental health has been recently exemplified. However, studies that have examined the implication of PTSS of both fathers and mothers in the intergenerational transmission of trauma to offspring are still lacking. This prospective study assessed the unique and combined effects of former prisoners of war (ex-POWs) fathers' and mothers' PTSS in adult offspring's PTSS. METHOD: A sample of 123 Israeli father-mother-offspring triads (79 ex-POW triads and a comparable group of 44 veteran triads) completed self-report measures. Following the 1973 Yom Kippur War, fathers participated in 3 waves of measurements (1991, 2003, 2008), mothers participated in 2 waves of measurements (2004, 2011), while offspring took part in 2014. RESULTS: Both fathers' and mothers' PTSS were positively related to offspring's PTSS. Among ex-POW triads, fathers' PTSS in 2003 and 2008 and mothers' PTSS in 2004 predicted offspring's PTSS in 2014. Interestingly, serial multiple mediation model results showed that mothers' PTSS in 2004 mediated the link between fathers' PTSS in 1991 and offspring's PTSS in 2014. Furthermore, fathers' PTSS in 2008 mediated the link between mothers' PTSS in 2004 and offspring's PTSS in 2014. CONCLUSIONS: Over time, both ex-POWs fathers' and mothers' PTSS are implicated in their offspring's PTSS. However, both direct and indirect effects of both parents' posttraumatic reactions contribute to the intergenerational transmission of captivity related trauma. (PsycINFO Database Record PMID- 27710008 TI - Anticipatory fear and helplessness predict PTSD and depression in domestic violence survivors. AB - OBJECTIVE: Embracing the conceptual framework of contemporary learning theory, this study tested the hypothesis that anticipatory fear due to a sense of ongoing threat to safety and sense of helplessness in life would be the strongest determinants of PTSD and depression in domestic violence survivors. METHOD: Participants were 220 domestic violence survivors recruited consecutively from 12 shelters for women in Turkey (response rate 70%). They were assessed with the Semi-Structured Interview for Survivors of Domestic Violence, Traumatic Stress Symptom Checklist, Depression Rating Scale, and Fear and Sense of Control Scale. RESULTS: Survivors were exposed to 21 (SD = 6.7) physical, psychological, and sexual violence stressors over 11.3 (SD = 8.8) years. They reported high levels of peritrauma perceived distress of and lack of control over stressor events. Approximately 10 months after trauma, many feared reliving the same domestic violence events, felt helpless, feared for their life, and felt in danger. PTSD and depression rates were 48.2% and 32.7%, respectively. The strongest predictors of PTSD and depression were fear due to a sense of ongoing threat to safety and sense of helplessness in life, which explained the largest amount of variances in these psychiatric conditions. CONCLUSION: The findings support the contemporary learning theory of traumatic stress and are consistent with findings of studies involving earthquake, war, and torture survivors. They imply that trauma-focused interventions designed to overcome fear, reduce helplessness, and restore sense of control over one's life would be effective in PTSD and depression in domestic violence survivors. (PsycINFO Database Record PMID- 27710009 TI - Effects of a brief education and treatment-planning group on evidence-based PTSD treatment utilization and completion among veterans. AB - OBJECTIVE: Veterans with posttraumatic stress disorder (PTSD) presenting for care with Veterans Affairs Health Care System (VA) tend not to engage in evidence based psychotherapies (EBPs) despite widespread availability of these treatments. Though there is little evidence that "readiness for treatment" affects treatment choice, many VA providers believe that interventions to increase readiness would be helpful. This naturalistic study examined the effects of a 4-session education/treatment-planning group on treatment choice among veterans in a VA outpatient PTSD treatment program. METHOD: Treatment choices and completion rates of 114 veterans who received at least 1 session of the group (EG) were compared with those of 68 veterans who did not receive the group and received PTSD program treatment as usual (TAU). TAU and EG cases were matched on gender and service era. RESULTS: Of 114 EG cases, 52 (45.6%) chose to receive EBPs, compared with 10 of 68 TAU cases (14.7%). These rates were significantly different, chi2(1) = 18.1, p < .0001. Among cases choosing EBPs, 52.2% of EG cases completed the EBPs as planned, compared with 60% of TAU cases. These percentages were not significantly different. Among EG cases choosing EBPs, lower likelihood of treatment completion was related to psychiatric medication prescription, presence of PTSD service connection, and higher overall service-connection level. CONCLUSION: The education/treatment-planning group was associated with higher likelihood of selecting but not completing EBPs for PTSD. The decision to engage in trauma-focused treatment may be a different process from the decision to complete such treatment. (PsycINFO Database Record PMID- 27710012 TI - Mechanistic Studies of Capsaicin-Induced Apnea in Rodents. AB - Inhalation of capsaicin-based sprays can cause central respiratory depression and lethal apneas. There are contradictory reports regarding the sites of capsaicin action. Furthermore, an understanding of the neurochemical mechanisms underlying capsaicin-induced apneas and the development of pharmacological interventions is lacking. The main objectives of this study were to perform a systematic study of the mechanisms of action of capsaicin-induced apneas and to provide insights relevant to pharmacological intervention. In vitro and in vivo rat and transient receptor potential vanilloid superfamily member 1 (TRPV1)-null mouse models were used to measure respiratory parameters and seizure-like activity in the presence of capsaicin and compounds that modulate glutamatergic neurotransmission. Administration of capsaicin to in vitro and in vivo rat and wild-type mouse models induced dose-dependent apneas and the production of seizure-like activity. No significant changes were observed in TRPV1-null mice or rat medullary slice preparations. The capsaicin-induced effects were inhibited by the TRPV1 antagonist capsazepine, amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA) receptor antagonists CNQX, NBQX, perampanel, and riluzole, a drug that inhibits glutamate release and increases glutamate uptake. The capsaicin-induced effects on breathing and seizure-like activity were accentuated by positive allosteric modulators of the AMPA receptors, CX717 and cyclothiazide. To summarize, capsaicin-induced apneas and seizure-like behaviors are mediated via TRPV1 activation acting at lung afferents, spinal cord-ascending tracts, and medullary structures (including nucleus tractus solitarius). AMPA receptor-mediated conductances play an important role in capsaicin-induced apneas and seizure-like activity. A pharmaceutical strategy targeted at reducing AMPA receptor-mediated glutamatergic signaling may reduce capsaicin-induced deleterious effects.

PMID- 27710013 TI - Parent-Reported Bullying and Child Weight Gain between Ages 6 and 15. AB - BACKGROUND: Childhood bullying has long-term negative mental and physical health correlates, including weight gain and symptoms of depression. The purpose of this research is to examine whether bullying in the first year of school is associated with greater weight gain by early adolescence and whether adolescent depressive symptoms mediate this association. METHODS: Data were drawn from the Longitudinal Study of Australian Children. Children (N = 3929) were measured every 2 years; BMI and waist circumference were available from ages 4 to 15. Parents reported on bullying at age 6. Children reported on their depressive symptoms at ages 12-13. RESULTS: Participants who weighed in the obese category at age 4 had an over 50% increased risk of being bullied in school at age 6. Being bullied at age 6 was associated with excess weight gain between ages 6 and 15, defined as either BMI or waist circumference. Depressive symptoms at age 12 partially explained the association between bullying and increases in adiposity. None of the associations varied by gender. CONCLUSIONS: Similar to other forms of peer victimization, bullying early in school is associated with greater weight gain through early adolescence; depressive symptom is one mechanism that contributes to this association. PMID- 27710014 TI - CT-based follow-up following radiotherapy or radiochemotherapy for locally advanced head and neck cancer; outcome and development of a prognostic model for regional control. AB - OBJECTIVE: The purpose of this study was to make a prognostic model for regional relapse in head and neck cancer using clinical and CT parameters. METHODS: 183 patients with lymph node-positive head and neck cancer were treated between 2002 and 2012 with radiotherapy or concurrent chemoradiotherapy. CT studies pre- and post-treatment were reviewed for lymph node size and the presence of necrosis, extracapsular spread (ECS) and calcifications. For every patient, correlations with 3-year regional control (RC), metastasis-free survival (MFS), disease-free survival (DFS) and overall survival (OS) were made. RESULTS: 3-year outcome rates were as follows: local control of 84%, RC of 80%, MFS of 74%, DFS of 61% and OS of 63%. Pre-treatment nodal size and the presence of necrosis were associated with a poorer outcome. This was also the case for post-treatment lymph node size, the presence of necrosis and ECS. We developed a CT-based prognostic model for RC with an area under the curve of 0.78 (95% confidence interval 0.63; 0.85). CONCLUSION: We reached a good outcome in our patient cohort using a CT-based follow-up approach. A CT-based model was developed, which can aid in predicting RC. Advances in knowledge: A prognostic model is proposed, which can aid in predicting RC and the necessity for post-radiotherapy neck dissection using clinical parameters and parameters derived from the post-treatment CT study. This is the first article to propose a prognostic model for regional relapse in head and neck cancer based on these parameters. PMID- 27710016 TI - Reducing the wait for emergency surgery.

PMID- 27710015 TI - Trends of Child's Weight Perception by Children, Parents, and Healthcare Professionals during the Time of Terminology Change in Childhood Obesity in the United States, 2005-2014. AB - OBJECTIVE: To investigate the changes on self- and parental weight perceptions and parental communication with healthcare professionals (HCPs) in the United States during the mid-2000s period when the terminology changed for classifications of childhood obesity/overweight. METHODS: A repeated cross sectional study was conducted with 6799 children aged 8-15 years with the National Health and Nutrition Examination Survey 2005-2014. BMI was calculated from objectively measured heights and weights, and children were classified as normal/underweight, overweight or obese, using the new terminology. Children reported their own weight status. Parents reported their child's weight status and reported how HCPs described their children's weight status. Logistic regressions were used to investigate changes in weight perceptions among overweight/obese children themselves and their parents and parental communication with HCPs about children's overweight/obesity status during the time of the terminology change. RESULTS: The proportion of parents told by HCPs about children's weight status increased for overweight children [6.8% in 2005-2006 to 18.8% in 2013-2014, p for trend (ptrend = 0.02)], and marginally increased between 2005-2006 (37.1%) and 2007-2008 (45.4%) for obese children (p = 0.09). However, parental perceptions for obese/overweight children did not change. Also, obese children's weight perception did not change, and the proportion of overweight children who perceived their weight status accurately declined in 2005 2012 (25.9%-16.4%, ptrend = 0.02). CONCLUSIONS: Although the terminology change about childhood obesity/overweight was associated with increased communication about child's weight status by HCPs, the accuracy of weight perceptions among obese/overweight children or their parents did not improve or declined.

PMID- 27710025 TI - Identification and Characterization of a Chloroplast-Targeted Obg GTPase in Dendrobium officinale. AB - Bacterial homologous chloroplast-targeted Obg GTPases (ObgCs) belong to the plant typical Obg group, which is involved in diverse physiological processes during chloroplast development. However, the evolutionarily conserved function of ObgC in plants remains elusive and requires further investigation. In this study, we identified DoObgC from an epiphytic plant Dendrobium officinale and demonstrated the characteristics of DoObgC. Sequence analysis indicated that DoObgC is highly conserved with other plant ObgCs, which contain the chloroplast transit peptide (cTP), Obg fold, G domain, and OCT regions. The C terminus of DoObgC lacking the chloroplast-targeting cTP region, DoObgCDelta1-160, showed strong similarity to ObgE and other bacterial Obgs. Overexpression of DoObgCDelta1-160 in Escherichia coli caused slow cell growth and an increased number of elongated cells. This phenotype was consistent with the phenotype of cells overexpressing ObgE. Furthermore, the expression of recombinant DoObgCDelta1-160 enhanced the cell persistence of E. coli to streptomycin. Results of transient expression assays revealed that DoObgC was localized to chloroplasts. Moreover, we demonstrated that DoObgC could rescue the embryotic lethal phenotype of the Arabidopsis obgc-t mutant, suggesting that DoObgC is a functional homolog to Arabidopsis AtObgC in D. officinale. Gene expression profiles showed that DoObgC was expressed in leaf specific and light-dependent patterns and that DoObgC responded to wounding treatments. Our previous and present studies reveal that ObgC has an evolutionarily conserved role in ribosome biogenesis to adapt chloroplast development to the environment.

AB - With the rapid growth of known protein 3D structures in number, how to efficiently compare protein structures becomes an essential and challenging problem in computational structural biology. At present, many protein structure alignment methods have been developed. Among all these methods, flexible structure alignment methods are shown to be superior to rigid structure alignment methods in identifying structure similarities between proteins, which have gone through conformational changes. It is also found that the methods based on aligned fragment pairs (AFPs) have a special advantage over other approaches in balancing global structure similarities and local structure similarities. Accordingly, we propose a new flexible protein structure alignment method based on variable-length AFPs. Compared with other methods, the proposed method possesses three main advantages. First, it is based on variable-length AFPs. The length of each AFP is separately determined to maximally represent a local similar structure fragment, which reduces the number of AFPs. Second, it uses local coordinate systems, which simplify the computation at each step of the expansion of AFPs during the AFP identification. Third, it decreases the number of twists by rewarding the situation where nonconsecutive AFPs share the same transformation in the alignment, which is realized by dynamic programming with an improved transition function. The experimental data show that compared with FlexProt, FATCAT, and FlexSnap, the proposed method can achieve comparable results by introducing fewer twists. Meanwhile, it can generate results similar to those of the FATCAT method in much less running time due to the reduced number of AFPs.

AB - BACKGROUND: Salmonella infection is one of the most common foodborne bacterial pathogens, and causes a significant health burden globally. We investigated the incidence and risk factors for notification and hospitalization due to Salmonella infection in older adults. MATERIALS AND METHODS: We used the 45 and Up Study, a large-scale Australian prospective study of adults aged >=45 years, with record linkage to multiple databases for the years 2006-2012 to estimate the incidence of notification and hospitalization for Salmonella infection and estimate hazard ratios using Cox regression. RESULTS: Over a total follow-up of 1,120,242 person years, 333 adults had laboratory-confirmed Salmonella infection and 101 were hospitalized; the notification and hospitalization incidence were 29.7 (95% confidence interval [CI]: 26.9-33.3) and 9.0 (95% CI: 7.4-10.9) per 100,000 person-years, respectively. The risk of Salmonella infection notification did not differ by age, but risk of hospitalization increased with age. Elderly males had the highest risk of infection-related hospitalization. The risk of notification was higher for those living in rural or remote areas (adjusted hazard ratio [aHR] 1.7, 95% CI 1.3-2.2), those taking proton pump inhibitors (aHR 1.9, 95% CI 1.4 2.4), and those reporting chicken/poultry intake at least seven times per week (aHR 3.2, 95% CI 1.3-7.9). CONCLUSIONS: Chicken consumption remains a significant risk factor for Salmonella infection, highlighting the importance of reducing contamination of poultry and improving food safety advice for older people.

PMID- 27710037 TI - Classification of biodegradable materials using QSAR modelling with uncertainty estimation. AB - The ability to determine the biodegradability of chemicals without resorting to expensive tests is ecologically and economically desirable. Models based on quantitative structure-activity relations (QSAR) provide some promise in this direction. However, QSAR models in the literature rarely provide uncertainty estimates in more detail than aggregated statistics such as the sensitivity and specificity of the model's predictions. Almost never is there a means of assessing the uncertainty in an individual prediction. Without an uncertainty estimate, it is impossible to assess the trustworthiness of any particular prediction, which leaves the model with a low utility for regulatory purposes. In the present work, a QSAR model with uncertainty estimates is used to predict biodegradability for a set of substances from a publicly available data set. Separation was performed using a partial least squares discriminant analysis model, and the uncertainty was estimated using bootstrapping. The uncertainty prediction allows for confidence intervals to be assigned to any of the model's predictions, allowing for a more complete assessment of the model than would be possible through a traditional statistical analysis. The results presented here are broadly applicable to other areas of modelling as well, because the calculation of the uncertainty will clearly demonstrate where additional tests are needed.

PMID- 27710048 TI - FastBill: An Improved Tool for Prediction of Cis-Regulatory Modules. AB - Here, we provide a new software tool, called FastBill, for prediction of evolutionarily conserved cis-regulatory modules. It improves on the previous version of our program, called Billboard, by improving the statistical significance calculation. It is also faster than the original Billboard, allowing for large-scale analyses, including multiple informant species. We illustrate the utility of FastBill by performing a large-scale computational experiment of enhancer prediction in the promoter area of more than 150 Drosophila melanogaster genes that possess annotated experimentally verified enhancers. FastBill is written in Python and is freely available for download as a standalone tool. PMID- 27710062 TI - Childhood injury prevention prevalence.

PMID- 27710070 TI - Making a difference. AB - A couple of months ago, I passed one of those milestones that I suppose we all pass sooner or later if we stay in the profession. I am now just over half my life in nursing. Over the years though, I have often been asked why I didn't do medicine instead. After all, it's said 'you're fairly bright wouldn't you have been better off'. The simple truth is, and although it may not be fashionable to say it too often these days, I am really proud of being a nurse. If I knew when I was 18 what I know now, I would still have made the same choice of career, except with fewer doubts. PMID- 27710071 TI - NHS Direct is launch pad for responsibility and status.

PMID- 27710081 TI - The Global Engagement in Care Convening: Recommended Actions to Improve Health Outcomes for People Living With HIV. AB - The National HIV AIDS Strategy (NHAS) calls for a more coordinated response to the HIV epidemic. The Global Engagement in Care Convening created a forum for domestic and international experts to identify best practices in HIV care. This manuscript summarizes the meeting discussions and recommendations from meeting notes and an audio recording of the meeting. Recommendations include: further standardization of performance goals and performance measures; additional research; a more robust system to support competing needs of clients receiving services; electronic information exchanges for HIV-related data; an expansion of the role of other health professionals to extend the capacity of physicians and other members of the care team; and revisions to current financing systems to increase reimbursement for and access to services that promote linkage to and retention in HIV care. The recommendations provide a unique example of "reverse technical assistance" and will inform U.S. program development, research, and policy. PMID- 27710082 TI - What Community-Based HIV Prevention Organizations Say About Their Role in Biomedical HIV Prevention. AB - Community-based organizations (CBOs) are critical to delivery of effective HIV prevention because of their reach to key populations. This online survey of a national sample of CBOs assessed their awareness of, interest in, and resources needed to provide nonoccupational postexposure prophylaxis (nPEP), preexposure prophylaxis (PrEP), and HIV treatment as prevention (TasP). One hundred seventy five CBOs participated: 87 clinical and 88 nonclinical CBOs. For nPEP, PrEP, and TasP, program managers reported that awareness was high (94%, 90%, 85%), meeting current client need was low (20%, 13%, 18%), and the likelihood of increasing their current provision with additional resources was somewhat high (62%, 64%, 62%). Clinical CBOs were more prepared to support expansion of these biomedical interventions than nonclinical CBOs. Meeting the information, training, and resource needs of CBOs is critical for effective collaboration to reduce the number of new HIV infections through expanded delivery of PrEP, nPEP, and TasP.

PMID- 27710083 TI - Social Desirability Response Bias and Other Factors That May Influence Self Reports of Substance Use and HIV Risk Behaviors: A Qualitative Study of Drug Users in Vietnam. AB - The accuracy of self-report data may be marred by a range of cognitive and motivational biases, including social desirability response bias. The current study used qualitative interviews to examine self-report response biases among participants in a large randomized clinical trial in Vietnam. A sample of study participants was reinterviewed. The vast majority reported being truthful and emphasized the importance of rapport with the study staff for achieving veridical data. However, some stated that rapport may lead to under reporting of risk behaviors in order not to disappoint study staff. Other factors that appeared to influence accuracy of self-reports include fear that the information may be divulged, desire to enroll in the study, length of the survey, and memory. There are several methods that can be employed to reduce response biases, and future studies should systematically address response bias and include methods to assess whether approaches and survey items are effective in improving accuracy of self report data. PMID- 27710085 TI - Using Online Settings to Identify Gay and Bisexual Men Willing to Take or With Experience Taking PrEP: Implications for Researchers and Providers. AB - Given the ongoing HIV epidemic, it is essential to identify gay and bisexual men who are interested in starting PrEP as well as active PrEP users. We report on online survey data gathered over a 17-month period in 2014-2015 from gay and bisexual men identified through six sources of recruitment (n = 2903): Facebook, a hookup website, two geosocial-sexual networking apps (herein "App 1: Pop-up ads" and "App 2: Banner ads"), and two types of listservs (one focused on general gay nightlife, and one focused on gay sex parties). Willingness to take PrEP were as follows: sex party listservs (71.3%), both apps (69.8%), Facebook (67.6%), hookup website (65.2%), and nightlife listservs (50.5%). Experience having taken PrEP was as follows: sex party listservs (23.4%), App 2: Banner ads (22.5%), nightlife listservs (17.1) Facebook (14.2%), App 1: Pop-up ads (12.4%), and hookup website (2.1%). In multivariable modeling, willingness to go on PrEP was independently associated with being younger, single, a person of color, and having been tested for HIV in the past 12 months. Source of recruitment was largely unassociated with willingness to start PrEP. Number of recent male partners, number of recent condomless anal sex (CAS) events, and when data were collected (i.e., time in months) were not significantly associated with willingness to start PrEP. In multivariable models, experience having taken PrEP was positively associated with sexual identity as gay, number of recent male sex partners, number of recent CAS acts, being tested for HIV in the past 12 months, and time (in months). Experience taking PrEP varied greatly by recruitment source, suggesting both researchers and providers might be well served to utilize digital mediums to effectively identify these individuals; however, should do so with caution as not all digital options may prove fruitful. PMID- 27710086 TI - Determinants of HIV Transmission Risk Among HIV-Infected Persons Engaged in Care. AB - People living with HIV (PLWH) engaged in medical care represent an accessible group to focus HIV prevention efforts. In an analysis of 1,883 PLWH from 2007 and 2015, we determined the proportion at risk of HIV transmission and identified factors associated with HIV transmission risk using multivariable mixed effects logistic regression models with random intercepts. HIV transmission risk was defined by an HIV viral load > 1,500 copies/mL and self-reported unprotected sex. We found that 174 (9.2%) individuals were at risk for HIV transmission at least once. Factors associated with HIV transmission risk included younger age (adjusted OR [95% CI] per decade decrease = 2.30 [1.84, 2.89]), illicit drug use (adjusted OR = 5.36 [3.02, 9.56]), depression (adjusted OR = 1.88 [1.10, 3.21]), and education <12th grade (adjusted OR = 2.05 [1.15, 3.67]). Thus, nearly 1 in 10 HIV-infected individuals engaged in care between 2007 and 2015 were potentially at risk of transmitting HIV. Behavioral interventions to decrease HIV transmission should focus on younger, less educated patients who are depressed and actively using illicit drugs. PMID- 27710087 TI - ProjectHeartforGirls.com: Development of a Web-Based HIV/STD Prevention Program for Adolescent Girls Emphasizing Sexual Communication Skills. AB - This article describes the development of ProjectHeartforGirls.com , an interactive web-based program designed to improve sexual communication skills and reduce the risk of HIV/STDs among adolescent girls, a population at heightened risk for negative sexual health outcomes (Centers for Disease Control and Prevention, 2013). Although sexual communication is a critical predictor of safer sex among teens, there are few online interventions that target these skills as a central program component. We developed ProjectHeartforGirls.com to fill this gap. Program development involved (1) identifying the target population (ethnically diverse high school girls), (2) clarifying the theoretical foundation (Reasoned Action Model), (3) conducting formative qualitative research (n = 25 girls), (4) drafting initial program content, (5) receiving ongoing feedback from a teen advisory board (n = 5 girls), (6) programming online content, and (7) conducting usability testing (n = 6 girls). These steps are described along with the final intervention product, which is currently being evaluated in a randomized controlled trial.

PMID- 27710089 TI - The Uses of Texting in Sexual Relationships Scale: Associations With Risky Sexual Behavior Among At-Risk African American Emerging Adults. AB - Qualitative and quantitative research was used to create the Uses of Texting in Sexual Relationships scale. At-risk, predominantly African American emerging adults participated in qualitative interviews (N = 20) and quantitative surveys (N = 110) about their uses of text messaging within romantic and sexual relationships. Exploratory factor analysis of items generated from interviews resulted in four subscales: Sexting, Relationship Maintenance, Relationship Development, and Texting for Sexual Safety. Exploratory analyses indicated associations of Sexting with more instances of condomless sex, and Texting for Sexual Safety with fewer instances of condomless sex, which was moderated by relationship power. Further research on the connections between text messaging in relationships and sexual behavior among high-risk and minority young adults is warranted, and intervention efforts to decrease sexual risks need to incorporate these avenues of sexual communication. PMID- 27710091 TI - Evaluation of 2 Heat-Mitigation Methods in Army Trainees. AB - CONTEXT: Heat injury is a significant threat to military trainees. Different methods of heat mitigation are in use across military units. Mist fans are 1 of several methods used in the hot and humid climate of Fort Benning, Georgia. OBJECTIVES: To determine if (1) the mist fan or the cooling towel effectively lowered participant core temperature in the humid environment found at Fort Benning and (2) the mist fan or the cooling towel presented additional physiologic or safety benefits or detriments when used in this environment. DESIGN: Randomized controlled clinical trial. SETTING: Laboratory environmental chamber. PATIENTS OR OTHER PARTICIPANTS: Thirty-five physically active men aged 19 to 35 years. INTERVENTION(S): (1) Mist fan, (2) commercial cooling towel, (3) passive-cooling (no intervention) control. All treatments lasted 20 minutes. Participants ran on a treadmill at 60% Vo2max. MAIN OUTCOME MEASURE(S): Rectal core temperature, heart rate, thermal comfort, perceived temperature, perceived wetness, and blood pressure. RESULTS: Average core temperature increased during 20 minutes of cooling (F1,28 = 64.76, P < .001, etap2 = 0.70), regardless of group (F1,28 = 3.41, P = .08, etap2 = 0.11) or condition (F1,28 < 1.0). Core temperature, heart rate, and blood pressure did not differ among the 3 conditions. Perceived temperature during 20 minutes of cooling decreased (F1,30 = 141.19, P < .001, etap2 = 0.83) regardless of group or condition. Perceived temperature was lower with the mist-fan treatment than with the control treatment (F1,15 = 7.38, P = .02, etap2 = 0.32). The mist-fan group perceived themselves to be cooler even at elevated core temperatures. CONCLUSIONS: The mist fan and cooling towel were both ineffective at lowering core temperature. Core temperature continued to increase after exercise in all groups. The mist fan produced feelings of coolness while the core temperature remained elevated, possibly increasing the risk of heat illness. PMID- 27710093 TI - A Comparison of Work Health and Safety Incidents and Injuries in Part-Time and Full-Time Australian Army Personnel. AB - CONTEXT: Part-time personnel are an integral part of the Australian Army. With operational deployments increasing, it is essential that medical teams identify the patterns of injuries sustained by part-time personnel in order to mitigate the risks of injury and optimize deployability. OBJECTIVE: To compare the patterns of reported work health and safety incidents and injuries in part-time and full-time Australian Army personnel. DESIGN: Retrospective cohort study. SETTING: The Australian Army. PATIENTS OR OTHER PARTICIPANTS: Australian Army Reserve and Australian regular Army populations, July 1, 2012, through June 30, 2014. MAIN OUTCOME MEASURE(S): Proportions of reported work health and safety incidents that resulted in injuries among Army Reserve and regular Army personnel and specifically the (a) body locations affected by incidents, (b) nature of resulting injuries, (c) injury mechanisms, and (d) activities being performed when the incidents occurred. RESULTS: Over 2 years, 15 065 work health and safety incidents and 11 263 injuries were reported in Army Reserve and regular Army populations combined. In the Army Reserve population, 85% of reported incidents were classified as involving minor personal injuries; 4% involved a serious personal injury. In the regular Army population, 68% of reported incidents involved a minor personal injury; 5% involved a serious personal injury. Substantially lower proportions of Army reservist incidents involved sports, whereas substantially higher proportions were associated with combat training, manual handling, and patrolling when compared with regular Army incidents. CONCLUSIONS: Army reservists had a higher proportion of injuries from Army work-related activities than did regular Army soldiers. Proportions of incidents arising from combat tasks and manual handling were higher in the Army Reserve. Understanding the sources of injuries will allow the medical teams to implement injury-mitigation strategies. PMID- 27710101 TI - In touch.

PMID- 27710100 TI - A randomized control trial evaluating fluorescent ink versus dark ink tattoos for breast radiotherapy. AB - OBJECTIVE: The purpose of this UK study was to evaluate interfraction reproducibility and body image score when using ultraviolet (UV) tattoos (not visible in ambient lighting) for external references during breast/chest wall radiotherapy and compare with conventional dark ink. METHODS: In this non blinded, single-centre, parallel group, randomized control trial, patients were allocated to receive either conventional dark ink or UV ink tattoos using computer-generated random blocks. Participant assignment was not masked. Systematic (?) and random (sigma) setup errors were determined using electronic portal images. Body image questionnaires were completed at pre-treatment, 1 month and 6 months to determine the impact of tattoo type on body image. The primary end point was to determine that UV tattoo random error (sigmasetup) was no less accurate than with conventional dark ink tattoos, i.e. <2.8 mm. RESULTS: 46 patients were randomized to receive conventional dark or UV ink tattoos. 45 patients completed treatment (UV: n = 23, dark: n = 22). sigmasetup for the UV tattoo group was <2.8 mm in the u and v directions (p = 0.001 and p = 0.009, respectively). A larger proportion of patients reported improvement in body image score in the UV tattoo group compared with the dark ink group at 1 month [56% (13/23) vs 14% (3/22), respectively] and 6 months [52% (11/21) vs 38% (8/21), respectively]. CONCLUSION: UV tattoos were associated with interfraction setup reproducibility comparable with conventional dark ink. Patients reported a more favourable change in body image score up to 6 months following treatment. Advances in knowledge: This study is the first to evaluate UV tattoo external references in a randomized control trial. PMID- 27710092 TI - Exploring the Perceptions of Newly Credentialed Athletic Trainers as They Transition to Practice. AB - CONTEXT: Research is limited on the transition to practice of newly credentialed athletic trainers (ATs). Understanding this transition could provide insight to assist employers and professional programs in developing initiatives to enhance the transition. OBJECTIVE: To explore newly credentialed ATs' experiences and feelings during their transition from student to autonomous practitioner. DESIGN: Qualitative study. SETTING: Individual phone interviews. PATIENTS OR OTHER PARTICIPANTS: Thirty-four ATs certified between January and September 2013 participated in this study (18 women, 16 men; age = 23.8 +/- 2.1 years; work settings were collegiate, secondary school, clinic, and other). Data saturation guided the number of participants. DATA COLLECTION AND ANALYSIS: Participants were interviewed via phone using a semistructured interview guide. All interviews were recorded and transcribed verbatim. Data were analyzed through phenomenologic reduction, with data coded for common themes and subthemes. Credibility was established via member checks, peer review, and intercoder reliability. RESULTS: The 3 themes that emerged from the data were (1) transition to practice preparation, (2) orientation, and (3) mentoring. Transition to practice was rarely discussed during professional preparation, but information on the organization and administration or capstone course (eg, insurance, documentation) assisted participants in their transition. Participants felt that preceptors influenced their transition by providing or hindering the number and quality of patient encounters. Participants from larger collegiate settings reported more formal orientation methods (eg, review policies, procedures manual), whereas those in secondary school, clinic/hospital, and smaller collegiate settings reported informal orientation methods (eg, independent review of policies and procedures, tours). Some participants were assigned a formal mentor, and others engaged in peer mentoring. CONCLUSIONS: Employers could enhance the transition to practice by providing formal orientation and mentorship. Professional programs could prepare students for the transition by discussing how to find support and mentoring and by involving preceptors who provide students with opportunities to give patient care.

PMID- 27710111 TI - Are BTS guidelines followed? AB - In 1993, the British Thoracic Society (BTS) issued guidelines for the management of spontaneous pneumothorax. The study's aim was to determine the level of adherence to these guidelines at a London teaching hospital. A retrospective case note audit of 59 episodes was performed. In patients undergoing intervention, the initial procedure was simple aspiration in 32 (73 per cent) and chest tube insertion in 12 (27 per cent) cases, contrasting with the BTS recommendation that aspiration should be attempted first in all such patients. Simple aspiration was successful on 34 per cent of occasions. Successful aspiration was associated with a significantly shorter hospital stay (median 3, range 1-11 days) than either failed aspiration (7, 3-66 days) or chest tube insertion without aspiration (9, 3 16 days). Other areas where practice differed from the BTS guidelines were clamping of chest tubes and use of a pursestring suture for wound closure. A follow up questionnaire suggested a lack of familiarity with the guidelines. These findings indicate that current management of spontaneous pneumothorax deviates from the BTS guidelines in potentially important respects. PMID- 27710112 TI - Plain ABDO X-rays: a waste of time? AB - Plain abdominal radiographs are commonly requested for acute medical emergencies on patients with non-specific abdominal symptoms and signs. In this study, 131 plain abdominal radiographs performed on the day of admission were prospectively analysed by the research team. In only 16 cases (12 per cent) the reasons for requests conformed to the recommended guidelines by the Royal College of Radiologists. The reason for the request was stated in the case notes in only three cases. In 62 cases (47 per cent), there was no comment made on the film by the requesting clinician. There was a discrepancy in the interpretation of the radiograph between the clinician and the radiologist in 31 cases (24 per cent). The clinical management was influenced by plain abdominal radiographs in only nine cases (7 per cent). The researchers argue that most plain abdominal radiographs requested on acute medical emergencies are inappropriate. They suggest there is a need to ensure guidelines are followed to prevent unnecessary exposure of patients to radiation as well as preventing expenditure on irrelevant investigations.

PMID- 27710115 TI - Cross-Validation of Data Compatibility Between Small Angle X-ray Scattering and Cryo-Electron Microscopy. AB - Cryo-electron microscopy (EM) and small angle X-ray scattering (SAXS) are two different data acquisition modalities often used to glean information about the structure of large biomolecular complexes in their native states. A SAXS experiment is generally considered fast and easy but unveils the structure at very low resolution, whereas a cryo-EM experiment needs more extensive preparation and postacquisition computation to yield a three-dimensional (3D) density map at higher resolution. In certain applications, we may need to verify whether the data acquired in the SAXS and cryo-EM experiments correspond to the same structure (e.g., before reconstructing the 3D density map in EM). In this article, a simple and fast method is proposed to verify the compatibility of the SAXS and EM experimental data. The method is based on averaging the two dimensional correlation of EM images and the Abel transform of the SAXS data. Orientational preferences are known to exist in cryo-EM experiments, and we also consider these effects on our method.

PMID- 27710130 TI - Examining Live-In Foreign Domestic Helpers as a Coping Resource for Family Caregivers of People With Dementia in Singapore. AB - In Singapore, the responsibility of caring for persons with dementia falls on family members who cope with a long-term caregiver burden, depending on available support resources. Hiring foreign domestic workers to alleviate caregiver burden becomes a prevalent coping strategy that caregivers adopt. This strategy allows caregivers to provide home care as part of fulfilling family obligations while managing the caregiver burden. This study aimed to investigate primary caregivers' relationship with hired support and its impact on coping with caregiver burden. Twenty in-depth interviews were conducted with primary caregivers who hired live-in domestic helpers to take care of their family members with dementia. The findings revealed that caregivers perceived the normative obligations to provide home care to family members with dementia. They sought support from domestic helpers to cope with physical and mental burnout, disruption of normal routines, and avoidance of financial strain. A mutual support relationship was built between caregivers and domestic helpers through trust and interdependence. The presence of domestic helpers as a coping resource reveals the positive outcomes of problem-, emotional-, and diversion-focused coping. This study illustrates that coping strategies are employed in different ways depending on the needs of caregivers, access to infrastructure, cultural expectations, and available resources.

AB - Ubiquitous Internet access currently revolutionizes the way people acquire information by creating a complex, worldwide information network. The impact of Internet use on the doctor-patient relationship is a moving target that varies across sociodemographic strata and nations. To increase scientific knowledge on the patient-Web-physician triangle in Austria, this study reports findings regarding prevailing online health information-seeking behavior and the respective impact on doctor-patient interactions among a nonprobability convenience sample of Internet users. To investigate digital age group-specific influences, we analyzed whether digital natives and digital immigrants differed in their perspectives. The questionnaire-based online survey collected sociodemographic data and online health information-seeking behavior from a sample of 562 respondents (59% females, mean age 37 +/- 15 years, 54% digital natives). Most respondents (79%) referred to the Internet to seek health information, making it the most commonly used source for health information, even more prevalent then the doctor. We found similar predictors for using the Internet as a source for health-related information across digital age groups. Thus, the overall generational gap seems to be small among regular Internet users in Austria. However, study participants expressed a rather skeptical attitude toward electronic exchange of health data between health care professionals and patients, as well as toward reliability of online health information. To improve adoption of electronic doctor-patient communication and patient empowerment, public education and awareness programs are required to promote consumer-centered health care provision and patient empowerment. PMID- 27710133 TI - Identifying key areas for active interprofessional learning partnerships: A facilitated dialogue. AB - Student and service user involvement is recognised as an important factor in creating interprofessional education (IPE) opportunities. We used a team-based learning approach to bring together undergraduate health professional students, early career professionals (ECPs), public partners, volunteers, and carers to explore learning partnerships. Influenced by evaluative inquiry, this qualitative study used a free text response to allow participants to give their own opinion. A total of 153 participants (50 public partners and 103 students and professionals representing 11 healthcare professions) took part. Participants were divided into mixed groups of six (n = 25) and asked to identify areas where students, professionals, and public could work together to improve health professional education. Each group documented their discussions by summarising agreed areas and next steps. Responses were collected and transcribed for inductive content analysis. Seven key themes (areas for joint working) were identified: communication, public as partners, standards of conduct, IPE, quality improvement, education, and learning environments. The team-based learning format enabled undergraduate and postgraduate health professionals to achieve consensus with public partners on areas for IPE and collaboration. Some of our results may be context-specific but the approach is generalisable to other areas. PMID- 27710134 TI - Patient-reported and economic outcomes related to sofosbuvir and ledipasvir treatment for chronic hepatitis C. AB - INTRODUCTION: We used published literature from 2013-2016, to review data regarding the new all oral interferon and ribavirin free direct acting antiviral (DAA's) treatment regimens. Areas covered: Specifically, this paper will address DAA's clinical efficacy, their associated patient reported outcomes, their adherence to treatment, and their cost-effectiveness of treatment using studies from the United States. Expert commentary: The current data suggest that cure and elimination of HCV appears to be on the horizon; however, more research is needed to verify similar results from real world practices. Further, research is also needed to overcome the barriers to treatment (lack of education and awareness of HCV, inadequate diagnosis technology, and lack of access and link to care) in order for the elimination of HCV to be obtained. PMID- 27710135 TI - Pharmacodynamic and pharmacokinetic evaluation of insulin glargine U300 for the treatment of type 1 diabetes. AB - INTRODUCTION: Glargine 300 units/ml (Gla-300) is a novel basal insulin formulation approved in 2015 for the treatment of diabetes. This more concentrated form of glargine causes delayed redissolution from the subcutaneous depot after injection and thus altered action profile. Areas covered: The pharmacokinetics, pharmacodynamics, efficacy, and safety of Gla-300 in patients with type 1 diabetes mellitus (T1DM) will be reviewed. Expert opinion: Gla-300 has a flatter and more prolonged pharmacokinetic profile compared to glargine 100 units/ml (Gla-100), but is less potent on a unit per unit basis. The prolonged duration of Gla-300 should provide 24h coverage with a single daily dose in all patients. Two phase III trials comparing Gla-300 and Gla-100 were conducted in patients with T1DM. A1C reduction and other measures of glycemic control were similar between groups. Hypoglycemia rates were similar among groups in one trial, but favored Gla-300 in the other. Evidence for improvement in hypoglycemia with Gla-300 is more convincing in the type 2 diabetes population. Gla-300 is available in an insulin pen to mitigate potential dosing errors with different glargine concentrations; the maximum dose per injection is 80 units. Future research should include direct comparison with degludec and use in insulin resistant populations. PMID- 27710136 TI - Letter in response to "Idarucizumab for dabigatran overdose".

AB - Provider-client interaction is an integral of clinical practice and central to the delivery of high-quality medical care. This article examines factors related to the provider-client interaction in the context of methadone maintenance treatment (MMT). Data were collected from 68 MMT clinics in China. In total, 418 service providers participated in the survey. Linear mixed effects regression models were performed to identify factors associated with provider-client interaction. It was observed that negative attitude toward drug users was associated with lower level of provider-client interaction and less time spent with each client. Other factors associated with lower level of interaction included being female, being younger, being a nurse, and fewer years in medical field. Higher provider-client interaction was associated with provider reported job satisfaction. The findings of this study call for a need to address provider negative attitudes that can impact provider-client interaction and the effectiveness of MMT. Future intervention efforts targeting MMT providers should be tailored by gender, provider type, and medical experiences. PMID- 27710138 TI - The Transformative Power of Authentic Conversations About Cancer. AB - Entertainment-education (E-E) assumes that actors performing content should be ethnically and culturally homogeneous with targeted audiences. The present study challenges this basic E-E assumption. Findings are presented from audience members who viewed When Cancer Calls... This theatrical production was constructed from verbatim transcriptions of naturally occurring telephone conversations between White family members as they communicated about and through their cancer journey. Non-White audience members were significantly more likely than White audience members to (a) regard the performance as authentic, (b) find it would influence "people like me," and (c) recommend the production to others. These findings suggest that all people must rely on communication when facing health challenges together. Such interactions that are fundamental to family membership are thus primal for the human social condition, regardless of differences in race and ethnicity. These findings also suggest innovative approaches to E-E health interventions that may contradict traditional market segmentation theories based on cultural differences and the principle of homophily. PMID- 27710139 TI - Higher pulse pressure/stroke volume index is associated with impaired outcome in hypertensive patients with left ventricular hypertrophy the LIFE study. AB - We tested the prognostic impact of a marker of arterial stiffness, pulse pressure/stroke volume index (PP/SVi), in patients with hypertension and left ventricular (LV) hypertrophy. We used data from 866 patients randomized to losartan or atenolol-based antihypertensive treatment, over a median of 4.8 years, in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study. The association of PP/SVi with outcomes was tested in Cox regression analyses and reported as hazard ratio (HR) and 95% confidence intervals (CI). In multivariate regression, reduction of PP/SVi was independently associated with male gender, reduction in systolic blood pressure (BP) and relative wall thickness and with an increase in left ventricular ejection fraction (all p < .05). After adjusting for confounders, higher baseline PP/SVi predicted a 38% higher hazard of combined major fatal and non-fatal cardiovascular events (95% CI 1.04-1.84), and higher hazard of cardiovascular mortality (HR 2.35 (95% CI 1.59 3.48) and stroke (HR 1.45 (95% CI 1.06-1.99) (all p < .05). Higher PP/SVi also predicts higher rate of hospitalization for HF (HR 2.15 (95% CI 1.48-3.12) and a 52% higher hazard of all-cause mortality (95% CI 1.10-2.09) (both p < .05). In hypertensive patients with electrocardiographic LV hypertrophy, higher PP/SVi was associated with increased cardiovascular morbidity and mortality. PMID- 27710140 TI - Risk factors and prophylaxis against invasive fungal disease for haematology and stem cell transplant recipients: an evolving field. AB - INTRODUCTION: Due to increasing intensity and complexity of therapies and longer survivorship, many patients with haematologic malignancy (HM) are at risk of invasive fungal disease (IFD). Mortality from IFD is high and treatment of an episode of IFD results in an excess length of hospital stay and costs and delays delivery of curative therapy of the underlying haematologic condition. Therefore, prevention and early recognition and treatment of IFD are crucial. Areas covered: Risk factors particular to certain HMs and haematopoietic stem cell transplantation, as well as those risk factors universal to all HM groups are examined. Expert commentary: Risk stratification identifies those patients who would benefit most from mould active versus yeast active prophylaxis and those who can be safely managed with monitoring and clinically driven interventions for IFD. This approach aids in antifungal stewardship. PMID- 27710142 TI - Corrigendum. PMID- 27710141 TI - Effects of phytoestrogens on bone mineral density during the menopause transition: a systematic review of randomized, controlled trials. AB - INTRODUCTION: Menopause is associated with increased bone resorption and decreased bone mineral density (BMD). Phytoestrogens are believed to prevent bone loss. This study reviewed relevant randomized, controlled trials to determine the effects of phytoestrogens on BMD in postmenopausal women. METHODS: In order to perform this systematic review, PubMed, Science Direct, Scopus, Cochrane Library, ISI Web of Knowledge, and ProQuest databases were searched for articles published during 2005-2016. The main keywords used during the searches were "phytoestrogen" and "bone mineral density" and "menopause". The Cochrane Risk of Bias Assessment Tool was used to evaluate the quality of the selected studies and to assess the risk of bias. RESULTS: A total of 23 eligible studies were included in this systematic review. Most selected studies used a double-blind, placebo-controlled design. In total, 3494 participants were enrolled in the selected trials. Different types of soy isoflavone extracts, including genistein extracts (either alone or in combination with daidzein), dietary products containing different amounts of phytoestrogens, and red clover extracts were used in the designed interventions. The duration of the interventions ranged from 7 weeks to 3 years. In most studies, the primary outcome was the efficacy of the designed intervention which was assessed through measuring whole body or regional BMD or bone mineral content, T-scores, and biomarkers of bone metabolism. CONCLUSIONS: Isoflavones probably have beneficial effects on bone health in menopausal women. Nevertheless, there were controversial reports about changes in BMD. Supplementation with a phytoestrogen can probably prevent the reduction in BMD and maintain a healthy bone structure during menopause. PMID- 27710143 TI - The future development of bacteria fighting medical devices: the role of graphene oxide. AB - INTRODUCTION: The clinical challenge that research on antibacterial coatings faces nowadays is the need of reduction of resistant bacterial infections, major source of implant rejection and repeated surgery. In order to avoid microorganisms attachment and biofilm formation, coating materials on medical devices have been developed with shortcomings represented by short-term durability and induction of new mechanisms of bacterial resistance. Graphene based films and hydrogel could represent the next generation protective coatings due to their excellent mechanical, chemical and thermal properties, high nanoparticle adsorption and antibacterial action. Areas covered: In this short commentary, we will report the recent developments of graphene oxide based coatings. Graphene oxide is a water-soluble derivative of graphene that allows high drug loading and miscibility with polymers, making it mouldable in any desired shape. Recent applications in wound healing and tissue engineering will be discussed as well as critical issues prior to clinical use of graphene oxide coatings. Expert commentary: The current evidence is insufficient to establish the efficacy of Graphene Oxide against bacteria and the durability of coatings. Further studies should clarify how to control Graphene Oxide antibacterial mechanism. PMID- 27710145 TI - Extreme Rapid Weight Loss and Rapid Weight Gain Observed in UK Mixed Martial Arts Athletes Preparing for Competition. AB - There is a lack of research documenting the weight-making practices of mixed martial-arts (MMA) competitors. The purpose of the investigation was to quantify the magnitude and identify the methods of rapid weight loss (RWL) and rapid weight gain (RWG) in MMA athletes preparing for competition. Seven athletes (mean +/- SD, age 24.6 +/- 3.5 yrs, body mass 69.9 +/- 5.7 kg, competitive experience 3.1 +/- 2.2 yrs) participated in a repeated-measures design. Measures of dietary intake, urinary hydration status, and body mass were recorded in the week preceding competition. Body mass decreased significantly (p < .0005) from baseline by 5.6 +/- 1.4 kg (8 +/- 1.8%). During the RWG period (32 +/- 1 hr) body mass increased significantly (p < .001) by 7.4 +/- 2.8 kg (11.7 +/- 4.7%), exceeding RWL. Mean energy and carbohydrate intake were 3176 +/- 482 kcal?day-1 and 471 +/- 124 g?day-1, respectively. At the official weigh-in 57% of athletes were dehydrated (1033 +/- 19 mOsmol?kg-1) and the remaining 43% were severely dehydrated (1267 +/- 47 mOsmol?kg-1). Athletes reported using harmful dehydration based RWL strategies, including sauna (43%) and training in plastic suits (43%). Results demonstrated RWG greater than RWL, this is a novel finding and may be attributable to the 32 hr duration from weigh-in till competition. The observed magnitude of RWL and strategies used are comparable to those which have previously resulted in fatalities. Rule changes which make RWL impractical should be implemented with immediate effect to ensure the health, safety and wellbeing of competitors. PMID- 27710144 TI - Lentiviral Vector Gene Transfer of Endostatin/Angiostatin for Macular Degeneration (GEM) Study. AB - Neovascular age-related macular degeneration (NVAMD) is a prevalent cause of vision loss. Intraocular injections of VEGF-neutralizing proteins provide benefit, but many patients require frequent injections for a prolonged period. Benefits are often lost over time due to lapses in treatment. New treatments that sustain anti-angiogenic activity are needed. This study tested the safety and expression profile of a lentiviral Equine Infectious Anemia Virus (EIAV) vector expressing endostatin and angiostatin (RetinoStat(r)). Patients with advanced NVAMD were enrolled at three centers in the United States, and the study eye received a subretinal injection of 2.4 * 104 (n = 3), 2.4 * 105 (n = 3), or 8.0 * 105 transduction units (TU; n = 15). Each of the doses was well-tolerated with no dose-limiting toxicities. There was little or no ocular inflammation. There was one procedure-related serious adverse event (AE), a macular hole, which was managed without difficulty and resolved. There was a vector dose-related increase in aqueous humor levels of endostatin and angiostatin with high reproducibility among subjects within cohorts. Mean levels of endostatin and angiostatin peaked between 12 and 24 weeks after injection of 2.4 * 105 TU or 8.0 * 105 TU at 57-81 ng/mL for endostatin and 15-27 ng/mL for angiostatin, and remained stable through the last measurement at week 48. Long-term follow-up demonstrated expression was maintained at last measurement (2.5 years in eight subjects and >4 years in two subjects). Despite an apparent reduction in fluorescein angiographic leakage that broadly correlated with the expression levels in the majority of patients, only one subject showed convincing evidence of anti-permeability activity in these late-stage patients. There was no significant change in mean lesion size in subjects injected with 8.0 * 105 TU. These data demonstrate that EIAV vectors provide a safe platform with robust and sustained transgene expression for ocular gene therapy. PMID- 27710146 TI - High Prevalence of Dehydration and Inadequate Nutritional Knowledge Among University and Club Level Athletes. AB - Although dehydration of >= 2% body weight (BW) loss significantly impairs endurance performance, dehydration remains prevalent among athletes and may be owing to a lack of knowledge in relation to fluid requirements. The aim of this study was to assess the hydration status of university/club level athletes (n = 430) from a range of sports/activities (army officer cadet training; bootcamp training; cycling; Gaelic Athletic Association camogie, football and hurling; golf; hockey; netball; rugby; running (sprinting and endurance); Shotokan karate and soccer) immediately before and after training/competition and to assess their nutritional knowledge. Urine specific gravity (USG) was measured immediately before and after exercise and BW loss during exercise was assessed. Nutritional knowledge was assessed using a validated questionnaire. 31.9% of athletes commenced exercise in a dehydrated state (USG >1.020) with 43.6% of participants dehydrated posttraining/competition. Dehydration was particularly prevalent (>40% of cohort) among karateka, female netball players, army officer cadets, and golfers. Golfers that commenced a competitive 18 hole round dehydrated took a significantly higher number of strokes to complete the round in comparison with their euhydrated counterparts (79.5 ?+/- 2.1 vs. 75.7 ?+/- 3.9 strokes, p = .049). Nutritional knowledge was poor among participants (median total score [IQR]; 52.9% [46.0, 59.8]), albeit athletes who were euhydrated at the start of exercise had a higher overall score in comparison with dehydrated athletes (55.2% vs. 50.6%, p = .001). Findings from the current study, therefore, have significant implications for the education of athletes in relation to their individual fluid requirements around exercise. PMID- 27710147 TI - Seasonal Variation in Vitamin D Status in Elite Athletes: A Longitudinal Study. AB - Studies monitoring vitamin D status in athletes are seldom conducted for a period of 12 months or longer, thereby lacking insight into seasonal fluctuations. The objective of the current study was to identify seasonal changes in total 25 hydroxyvitamin D (25(OH)D) concentration throughout the year. Fifty-two, mainly Caucasian athletes with a sufficient 25(OH)D concentration (>75 nmol/L) in June were included in this study. Serum 25(OH)D concentration was measured every three months (June, September, December, March, June). In addition, vitamin D intake and sun exposure were assessed by questionnaires at the same time points. Highest total 25(OH)D concentrations were found at the end of summer (113 +/- 26 nmol/L), whereas lowest concentrations were observed at the end of winter (78 +/- 30 nmol/L). Although all athletes had a sufficient 25(OH)D concentration at the start of the study, nearly 20% of the athletes were deficient (<50 nmol/L) in late winter. PMID- 27710148 TI - Fluid Retention and Utility of Practical Hydration Markers to Detect Three Levels of Recovery Fluid Intake in Male Runners. AB - Runners are unlikely to consume fluid during training bouts increasing the importance of recovery rehydration efforts. This study assessed urine specific gravity (USG) responses following runs in the heat with different recovery fluid intake volumes. Thirteen male runners completed 3 evening running sessions resulting in approximately 2,200 ?+/- 300 ml of sweat loss (3.1 ?+/- 0.4% body mass) followed by a standardized dinner and breakfast. Beverage fluid intake (pre/postbreakfast) equaled 1,565/2,093 ml (low; L), 2,065/2,593 ml (moderate; M) and 2,565/3,356 mL (high; H). Voids were collected in separate containers. Increased urine output resulted in no differences (p > .05) in absolute mean fluid retention for waking or first postbreakfast voids. Night void averages excluding the first void postrun (1.025 ?+/- 0.008; 1.013 ?+/- 0.008; 1.006 ?+/- 0.003), first morning (1.024 ?+/- 0.004; 1.015 ?+/- 0.005; 1.014 ?+/- 0.005), and postbreakfast (1.022 ?+/- 0.007; 1.014 ?+/- 0.007; 1.008 ?+/- 0.003) USG were higher (p < .05) for L versus M and H respectively and more clearly differentiated fluid intake volume between L and M than color or thirst sensation. Waking (r = -0.66) and postbreakfast (r = -0.71) USG were both significantly correlated (p < .001) with fluid replacement percentage, but not absolute fluid retention. Fluid intake M was reported as most similar to normal consumption (5.6 ?+/- 1.0 on 0-10 scale) after breakfast and equaled 122 ?+/- 16% of sweat losses. Retention data suggests consumption above this level is not warranted or actually practiced by most runners drinking ad libitum, but that periodic prerun USG assessment may be useful for coaches to detect runners that habitually consume low levels of fluids between training bouts in warm seasons. PMID- 27710149 TI - Heightened Exercise-Induced Oxidative Stress at Simulated Moderate Level Altitude vs. Sea Level in Trained Cyclists. AB - Altitude exposure can exaggerate the transient increase in markers of oxidative stress observed following acute exercise. However, these responses have not been monitored in endurance-trained cyclists at altitudes typically experienced while training. Endurance trained males (n = 12; mean (+/- SD) age: 28 +/- 4 years, VO2max 63.7 +/- 5.3 ml/kg/min) undertook two 75-min exercise trials at 70% relative VO2max; once in normoxia and once in hypobaric hypoxia, equivalent to 2000m above sea level (hypoxia). Blood samples were collected before, immediately after and 2 h postexercise to assess plasma parameters of oxidative stress (protein carbonylation (PC), thiobarbituric acid reactive substances (TBARS), total antioxidant capacity (TAC) and catalase activity (CAT)). Participants cycled at 10.5% lower power output in hypoxia vs. normoxia, with no differences in heart rate, blood lactate or rating of perceived exertion observed. PC increased and decreased immediately after exercise in hypoxia and normoxia respectively (nmol/mg/protein: Normoxia-0.3 +/- 0.1, Hypoxia + 0.4 +/- 0.1; both p < .05). CAT increased immediately postexercise in both trials, with the magnitude of change greater in hypoxia (nmol/min/ml: Normoxia + 12.0 +/- 5.0, Hypoxia + 27.7 +/- 4.8; both p < .05). CAT was elevated above baseline values at 2 h postexercise in Hypoxia only (Normoxia + 0.2 +/- 2.4, Hypoxia + 18.4 +/- 5.2; p < .05). No differences were observed in the changes in TBARS and TAC between hypoxia and normoxia. Trained male cyclists demonstrated a differential pattern/ timecourse of changes in markers of oxidative stress following submaximal exercise under hypoxic vs. normoxic conditions. PMID- 27710150 TI - Dietary Protein Intake and Distribution Patterns of Well-Trained Dutch Athletes. AB - Dietary protein intake should be optimized in all athletes to ensure proper recovery and enhance the skeletal muscle adaptive response to exercise training. In addition to total protein intake, the use of specific proteincontaining food sources and the distribution of protein throughout the day are relevant for optimizing protein intake in athletes. In the present study, we examined the daily intake and distribution of various proteincontaining food sources in a large cohort of strength, endurance and team-sport athletes. Well-trained male (n=327) and female (n=226) athletes completed multiple web-based 24-hr dietary recalls over a 2-4 wk period. Total energy intake, the contribution of animal- and plant-based proteins to daily protein intake, and protein intake at six eating moments were determined. Daily protein intake averaged 108+/-33 and 90+/ 24 g in men and women, respectively, which corresponded to relative intakes of 1.5+/-0.4 and 1.4+/-0.4 g/kg. Dietary protein intake was correlated with total energy intake in strength (r=0.71, p <.001), endurance (r=0.79, p <.001) and team sport (r=0.77, p <.001) athletes. Animal and plant-based sources of protein intake was 57% and 43%, respectively. The distribution of protein intake was 19% (19+/-8 g) at breakfast, 24% (25+/-13 g) at lunch and 38% (38+/-15 g) at dinner. Protein intake was below the recommended 20 g for 58% of athletes at breakfast, 36% at lunch and 8% at dinner. In summary, this survey of athletes revealed they habitually consume > 1.2 g protein/kg/d, but the distribution throughout the day may be suboptimal to maximize the skeletal muscle adaptive response to training. PMID- 27710151 TI - Exertional Hyponatremia and Serum Sodium Change During Ultraendurance Cycling. AB - INTRODUCTION: Exertional hyponatremia (EH) during prolonged exercise involves all avenues of fluid-electrolyte gain and loss. Although previous research implicates retention of excess fluid, EH may involve either loss, gain, or no change of body mass. Thus, the etiology, predisposing factors, and recommendations for prevention are vague-except for advice to avoid excessive drinking. PURPOSE: This retrospective field study presents case reports of two unacquainted recreational cyclists (LC, 31y and AM, 39 years) who began exercise with normal serum electrolytes but finished a summer 164-km ride (ambient, 34?+/-5 degrees C) with a serum [Na+] of 130 mmol/L. METHODS: To clarify the etiology of EH, their pre- and post-exercise measurements were compared to a control group (CON) of 31 normonatremic cyclists (mean ?+/- SD; 37?+/-6 years; 141?+/-3 mmol Na+/L). RESULTS: Anthropomorphic characteristics, exercise time, and post-exercise ratings of thermal sensation, perceived exertion and muscle cramp were similar for LC, AM and CON. These two hyponatremic cyclists consumed a large and similar volume of fluid (191 and 189 ml/kg), experienced an 11 mmol/L decrease of serum [Na+], reported low thirst sensations; however, LC gained 3.1 kg (+4.3% of body mass) during 8.9 hr of exercise and AM maintained body mass (+0.1kg, +0.1%, 10.6h). In the entire cohort (n = 33), post-event serum [Na+] was strongly correlated with total fluid intake (R2 = 0.45, p < .0001), and correlated moderately with dietary sodium intake (R2=0.28, p = .004) and body mass change (R2 = 0.22, p = .02). Linear regression analyses predicted the threshold of EH onset (<135 mmol Na+/L) as 168 ml fluid/kg. CONCLUSIONS: The wide range of serum [Na+] changes (+6 to -11 mmol/L) led us to recommend an individualized rehydration plan to athletes because the interactions of factors were complex and idiosyncratic.

PMID- 27710153 TI - Sex Difference in the Association Between Metabolic Syndrome and Left Ventricular Diastolic Dysfunction. AB - BACKGROUND: Sex-related differences in the influence of metabolic syndrome (MetS) on various cardiovascular diseases have been suggested. The aim of this study was to investigate the effect of sex on the association between MetS and left ventricular (LV) diastolic dysfunction in patients with suspected coronary artery disease (CAD). METHODS: Two hundred ten patients (105 men and age-matched 105 women; mean age: 56.5 +/- 10.9 years) undergoing elective coronary angiography for the evaluation of CAD were studied. MetS was defined according to the International Diabetes Federation criteria. LV diastolic function was assessed using transthoracic echocardiography. RESULTS: The incidence of MetS was 23.8% in men and 14.3% in women (P = 0.079). The incidence of LV diastolic dysfunction was significantly different by MetS in women, but not in men. In multiple linear regression analyses, the number of MetS components was independently associated with septal e' velocity, E/e', and left atrial (LA) diameter in women (P < 0.05 for each). In men, the number of MetS components was associated with only LA size in this analysis. As the number of components of MetS increased, septal e' velocity decreased proportionally in women (P < 0.001), but not in men (P = 0.117). CONCLUSIONS: Among middle-aged and elderly Korean patients at high risk of CAD, the impact of MetS on LV diastolic dysfunction was more pronounced in women than in men. This suggests the important role of sex hormonal effects in the development of LV diastolic dysfunction in relation to MetS in this population.

However, many personal trainers provide nutrition care beyond their scope of practice and this has been identified as a major industry risk due to a perceived lack of competence in nutrition. This paper explores the context in which personal trainers provide nutrition care, by understanding personal trainers' perceptions of nutrition care in relation to their role and scope of practice. Semistructured telephone interviews were conducted with 15 personal trainers working within Australia. Thematic analysis was used to identify key themes. All personal trainers reported to provide nutrition care and reported that nutrition care was an important component of their role. Despite this, many were unaware or uncertain of the scope of practice for personal trainers. Some personal trainers reported a gap between the nutrition knowledge they received in their formal education, and the knowledge they needed to optimally support their clients to adopt healthy dietary behaviors. Overall, the personal training context is likely to be conducive to providing nutrition care. Despite concerns about competence personal trainers have not modified their nutrition care practices. To ensure personal trainers provide nutrition care in a safe and effective manner, greater enforcement of the scope of practice is required as well as clear nutrition competencies or standards to be developed during training.

AB - BACKGROUND: There is limited research on how well the American College of Surgeons/Center for Disease Control and Prevention Guidelines for Field Triage of Injured Patients assist EMS providers in identifying children who need the resources of a trauma center. OBJECTIVE: To determine the accuracy of the Physiologic Criteria (Step 1) of the Field Triage Guidelines in identifying injured children who need the resources of a trauma center. METHODS: EMS providers who transported injured children 15 years and younger to pediatric trauma centers in 3 mid-sized cities were interviewed regarding patient demographics and the presence or absence of each of the Field Triage Guidelines criteria. Children were considered to have needed a trauma center if they had non orthopedic surgery within 24 hours, ICU admission, or died. This data was obtained through a structured hospital record review. The over- and under-triage rates and positive likelihood ratios (+LR) were calculated for the overall Physiologic Criteria and each individual criterion. RESULTS: Interviews were conducted for 5,610 pediatric patients; outcome data were available for 5,594 (99.7%): 5% of all patients needed the resources of a trauma center and 19% met the physiologic criteria. Using the physiologic criteria alone, 51% of children who needed a trauma center would have been under-triaged and 18% would have been over-triaged (+LR 2.8, 95% CI 2.4-3.2). Glasgow Coma Score (GCS) < 14 had a +LR of 14.3 (95% CI 11.2-18.3), with EMS not obtaining a GCS in 4% of cases. 54% of those with an EMS GCS < 14 had an initial ED GCS < 14. Abnormal respiratory rate (RR) had a +LR of 2.2 (95% CI 1.8-2.6), with EMS not obtaining a RR in 5% of cases. 41% of those with an abnormal EMS RR had an abnormal initial ED RR. Systolic blood pressure (SBP) < 90 had a +LR of 3.5 (95% CI 2.5-5.1), with EMS not obtaining a SBP in 20% of cases. SBP was not obtained for 79% of children <1 year, 46% 1-4 years, 7% 5-9 years, and 2% 10-15 years. A total of 19% of those with an EMS SBP < 90 had an initial ED SBP < 90. CONCLUSIONS: The Physiologic Criteria are a moderate predictor of trauma center need for children. Missing or inaccurate vital signs may be limiting the predictive value of the Physiologic Criteria.

AB - This review aims to explain risk factors, consequences, and management strategies recommended for patients with hypertriglyceridemia. A search of PubMed was performed: 'Hypertriglyceridemia'[Majr], limited to English-language and published in the 5 years up to April 2016. Abstracts of the 680 results were screened for inclusion. Reference lists of publications included were also screened for inclusion. Approximately 25% of the United States population has elevated (>=150 mg/dL) triglycerides (TG) putting them at an increased risk of cardiovascular disease, non-alcoholic fatty liver disease, and pancreatitis. Risk factors for hypertriglyceridemia include genetics, lifestyle and diet, renal disease, endocrine disorders, and certain medications. Guidelines recommend that all patients with hypertriglyceridemia are advised on lifestyle modification to reduce TG to <150 mg/dL; a reduction in body weight of 5-10% can reduce TG by approximately 20%. For patients with TG <400 mg/dL, the primary goal is to reduce low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol, with most guidelines recommending statin therapy. When TG is >=500 mg/dL the primary goal is to reduce TG levels to lower the risk of pancreatitis. Statin therapy (if LDL-C is elevated) in combination with a fibrate, or long chain omega-3 fatty acid may be required. The Food and Drug Administration withdrew approval for niacin and some fibrates in combination with statins in April 2016 citing unfavorable benefit-risk profiles. With the increasing incidence of associated conditions (e.g. obesity, metabolic syndrome, and type 2 diabetes mellitus), it is likely that primary care physicians will encounter more patients with hypertriglyceridemia. PMID- 27710159 TI - A population-based study on incidence rates, Lauren distribution, stage distribution, treatment, and long-term outcomes for gastric adenocarcinoma in Central Norway 2001-2011. AB - BACKGROUND: Population-based studies for gastric adenocarcinoma are scarce, particularly studies conducted within a defined geographical area with publicly available censuses that allow incidence rates to be calculated. MATERIAL AND METHODS: Population-based study in Central Norway from 2001 to 2011, covering a population of 636 000-680 000, respectively. Patients were identified through the Cancer Registry of Norway and the Norwegian Patient Register, and were characterized by data from individual electronic patient records. Outcomes were compared across the early and the late half of the study period. RESULTS: A total of 878 patients were identified with a median age of 76.2 years. The male to female ratio was 1.72. Annual world age-standardized incidence was 8.0/105 and 3.6/105, respectively. The Lauren diffuse type was significantly more frequent among patients below 60 years, among females and for non-cardia cancers, compared to their counterparts (p < .001). The Lauren mixed type had a stable proportion of around 13% irrespective of age, sex or tumor location. Early gastric cancers (EGC) represented 8.3% of the cases, whereas 44% of all patients were diagnosed with metastatic disease. In males, the proportion of cardia cancers increased from 29.7% to 39.1% during the study period (p = .005). The five-year overall survival was 16%, and was substantially better for the Lauren intestinal type compared to the diffuse type, log-rank p = .003. The R0-R1 resection rate was 39%, with a corresponding five-year survival of 40.9%. CONCLUSIONS: This study provides population-derived data lacking in hospital-based studies. Lauren categories with epidemiological aspects and clinical outcomes are displayed. Gastric cancer was associated with a dismal prognosis. Few patients had EGC and close to 50% had metastatic disease. Many were too old or frail to be considered for surgery. PMID- 27710160 TI - Treatment of Nonalcoholic Fatty Liver Disease with Long-Chain n-3 Polyunsaturated Fatty Acids in Humans. AB - BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a major risk factor for type 2 diabetes, cardiovascular disease, and liver failure. Treatment with n-3 long-chain polyunsaturated fatty acids (n-3 LCPUFAs) produced variable success in improving NAFLD. The purpose of this review is to determine if n-3 LCPUFA will decrease markers of NAFLD, compare the efficacies of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and identify factors that contribute to discrepancies in results. METHODS: This study reviewed published clinical studies with n-3 LCPUFA and NAFLD/nonalcoholic steatohepatitis (NASH) by using PubMed and Web of Science. RESULTS: Seventeen human studies ranging in DHA 250 mg/day to a mixture of EPA+DHA 50 mL/day for 8 weeks to 2 years were identified. Results obtained varied because of different dosages of n-3 LCPUFA, EPA and DHA ratios, duration, subject characteristics, diet, exercise, compliance, methods, and other factors. Despite inconsistencies in the results reported, 13 of 17 published studies reported that n-3 LCPUFA supplementation decreased liver fat, liver enzymes, or markers of inflammation; four reported decrease in ballooning and two in fibrosis. Results also indicated that DHA was more effective than EPA in the treatment of NAFLD. Caloric restriction and supplementation with n-3 LCPUFA were additive in decreasing hepatic steatosis. CONCLUSIONS: n-3 PUFA decreased several markers of NAFLD; however, there was a lower observed efficacy in NASH treatment. Further long-term placebo-controlled studies with adequate power and supplementation duration and standardized and sensitive detection methods are needed to determine the efficacy of EPA and DHA individually and in a mixture to treat NAFLD and NASH.

PMID- 27710162 TI - Factors Associated with Breast Cancer Screening in a Country with National Health Insurance: Did We Succeed in Reducing Healthcare Disparities? AB - BACKGROUND: The effectiveness of breast cancer screening programs in reducing mortality is well established in the scientific literature. The National Breast Cancer Screening Program in Israel provides biennial mammograms for women of average risk aged 50-74 and annual mammograms for women aged 40-49 at higher risk. Compliance is high, but differential. This study explores different factors associated with breast cancer screening attendance among women aged 40-74 years. MATERIALS AND METHODS: Two main outcomes were studied: ever been screened and been screened in the 2 years preceding the study, using the cross-sectional Knowledge, Attitudes and Practices (KAP) Survey conducted in 2010-2012 among 2575 Israeli women aged 21+ years. The independent variables were sociodemographic characteristics, perceived health status, lifestyle habits, and healthcare fund membership. Bivariate and multivariable logistic regressions were conducted. RESULTS: Of the 943 participants aged 50-74, 87% had ever been screened and 74.8% had attended screening for breast cancer in the last 2 years. In multivariable models, Jewish compared to Arab women (adjusted prevalence ratio [APR] = 2.09, 95% confidence interval [CI]: 1.02-4.32), and unmarried compared to married women (APR = 2.9, 95% CI: 1.2-7.2), were more likely to have ever been screened. The only factor associated with breast cancer screening in the 2 years preceding the study was healthcare fund membership. In women aged 40-49 years, ethnicity was the only contributing factor associated with breast cancer screening, with higher screening rates in the 2 years preceding the study in Jewish versus Arab women (APR = 3.7, 95% CI: 1.52-9.3). CONCLUSIONS: Breast cancer screening attendance in Israel is high. However, significant differences are observed by membership of healthcare fund and by ethnicity, calling for better targeted outreach programs at this level. PMID- 27710163 TI - Defining a Bobath clinical framework - A modified e-Delphi study. AB - OBJECTIVE: To gain consensus within the expert International Bobath Instructors Training Association (IBITA) on a Bobath clinical framework on which future efficacy studies can be based. METHODS: A three-round modified e-Delphi approach was used with 204 full members of the IBITA. Twenty-one initial statements were generated from the literature. Consensus was defined a priori as at least 80% of the respondents with a level of agreement on a Likert scale of 4 or 5. The Delphi questionnaire for each round was available online for two weeks. Summary reports and subsequent questionnaires were posted within four weeks. RESULTS: Ninety-four IBITA members responded, forming the Delphi panel, of which 68 and 66 responded to Rounds Two and Three, respectively. The 21 initial statements were revised to 17 statements and five new statements in Round Two in which eight statements were accepted and two statements were eliminated. Round Three presented 12 revised statements, all reaching consensus. CONCLUSION: The Delphi was successful in gaining consensus on a Bobath clinical framework in a geographically diverse expert association, identifying the unique components of Bobath clinical practice. Discussion throughout all three Rounds revolved primarily around the terminology of atypical and compensatory motor behavior and balance. PMID- 27710164 TI - An Ai Chi-based aquatic group improves balance and reduces falls in community dwelling adults: A pilot observational cohort study. AB - BACKGROUND: Falls are associated with morbidity, loss of independence, and mortality. While land-based group exercise and Tai Chi programs reduce the risk of falls, aquatic therapy may allow patients to complete balance exercises with less pain and fear of falling; however, limited data exist. OBJECTIVE: The objective of the study was to pilot the implementation of an aquatic group based on Ai Chi principles (Aquabalance) and to evaluate the safety, intervention acceptability, and intervention effect sizes. DESIGN: Pilot observational cohort study. METHODS: Forty-two outpatients underwent a single 45-minute weekly group aquatic Ai Chi-based session for eight weeks (Aquabalance). Safety was monitored using organizational reporting systems. Patient attendance, satisfaction, and self-reported falls were also recorded. Balance measures included the Timed Up and Go (TUG) test, the Four Square Step Test (FSST), and the unilateral Step Tests. RESULTS: Forty-two patients completed the program. It was feasible to deliver Aquabalance, as evidenced by the median (IQR) attendance rate of 8.0 (7.8, 8.0) out of 8. No adverse events occurred and participants reported high satisfaction levels. Improvements were noted on the TUG, 10-meter walk test, the Functional Reach Test, the FSST, and the unilateral step tests (p < 0.05). The proportion of patients defined as high falls risk reduced from 38% to 21%. The study was limited by its small sample size, single-center nature, and the absence of a control group. CONCLUSIONS: Aquabalance was safe, well-attended, and acceptable to participants. A randomized controlled assessor-blinded trial is required. PMID- 27710165 TI - Dietary Intake, Body Composition, and Nutrition Knowledge of Australian Football and Soccer Players: Implications for Sports Nutrition Professionals in Practice. AB - Sports nutrition professionals aim to influence nutrition knowledge, dietary intake and body composition to improve athletic performance. Understanding the interrelationships between these factors and how they vary across sports has the potential to facilitate better-informed and targeted sports nutrition practice. This observational study assessed body composition (DXA), dietary intake (multiple-pass 24-hr recall) and nutrition knowledge (two previously validated tools) of elite and subelite male players involved in two team-based sports; Australian football (AF) and soccer. Differences in, and relationships between, nutrition knowledge, dietary intake and body composition between elite AF, subelite AF and elite soccer players were assessed. A total of 66 (23 ?+/- 4 years, 82.0 ?+/- 9.2 kg, 184.7 ?+/- 7.7 cm) players participated. Areas of weaknesses in nutrition knowledge are evident (57% mean score obtained) yet nutrition knowledge was not different between elite and subelite AF and soccer players (58%, 57% and 56%, respectively, p > .05). Dietary intake was not consistent with recommendations in some areas; carbohydrate intake was lower (4.6 ?+/- 1.5 g/kg/day, 4.5 ?+/- 1.2 g/kg/day and 2.9 ?+/- 1.1 g/kg/day for elite and subelite AF and elite soccer players, respectively) and protein intake was higher (3.4 ?+/- 1.1 g/kg/day, 2.1 ?+/- 0.7 g/kg/day and 1.9 ?+/- 0.5 g/kg/day for elite and subelite AF and elite soccer players, respectively) than recommendations. Nutrition knowledge was positively correlated with fat-free soft tissue mass (n = 66; r2 = .051, p = .039). This insight into known modifiable factors may assist sports nutrition professionals to be more specific and targeted in their approach to supporting players to achieve enhanced performance. PMID- 27710166 TI - Professional roles in physiotherapy practice: Educating for self-management, relational matching, and coaching for everyday life. AB - The patient's active participation in treatment and rehabilitation represents a cultural change in clinical practice as well as a major change in physiotherapist and patient roles. This article presents findings from a study aimed at gaining a better understanding of how physiotherapists in actual practice understand their interactions with patients during the treatment process. This article reports on the findings from focus-group interviews with physiotherapists working in three different settings. Analyses of the interview data identified three modes of physiotherapy practice. In one, physiotherapists educate their patients to be self-managing in conducting exercise programs based on sound evidence. Educational films available on the Internet are included in these efforts to teach patients. In another, physiotherapists emphasize the importance of a close relationship to the patient. A good personal chemistry is believed to improve the treatment process. And finally, what physiotherapists learn about the living conditions and the biographies of their patients was shown to be very important. Understanding the importance of the life-world and taking this into consideration in the treatment process were factors considered to be central to good practice. The article concludes with a discussion linking these findings to those of other studies identifying those factors contributing to our knowledge of what is involved in biopsychosocial practice in physiotherapy. PMID- 27710179 TI - Polycyclic aromatic hydrocarbons in commercial brands of dry whole soybeans for direct human consumption. AB - A total of 13 polycyclic aromatic hydrocarbons (PAHs) were surveyed in dry whole soybeans (Glycine max L.) sold for human consumption. The analysed samples were commercialised in vegetarian shops and food stores in Southern Brazil regions. The determination of PAHs levels was carried out by high performance liquid chromatography (HPLC)with fluorescence detection. PAHs were present in 89.7% of the samples. Chrysene (Chy) and 5 methyl chrysene (5MeChy) were the main PAHs detected (76.9% and 71.8%, respectively) followed by dibenzo(ai)pyrene (DaiP), however in a much less percentage of samples (23.1%). Apart from those PAHs, also benzo(a)antracene (BaA), benzo(b)fluoranthene (BbF), benzo(k)fluoranthene (BkF) and benzo(a)pyrene(BaP) were found. The SigmaPAH levels in the positive samples ranged from 0.80 to 38.78 ug kg-1, with exception of one sample that reached 204.46 ug kg-1 (SigmaPAHs of six compounds). Despite the present contamination there are no maximum limits set for PAHs in soybeans. PMID- 27710180 TI - Modelling dimercaptosuccinic acid (DMSA) plasma kinetics in humans. AB - CONTEXT: No kinetic models presently exist which simulate the effect of chelation therapy on lead blood concentrations in lead poisoning. OBJECTIVE: Our aim was to develop a kinetic model that describes the kinetics of dimercaptosuccinic acid (DMSA; succimer), a commonly used chelating agent, that could be used in developing a lead chelating model. MATERIAL AND METHODS: This was a kinetic modelling study. We used a two-compartment model, with a non-systemic gastrointestinal compartment (gut lumen) and the whole body as one systemic compartment. The only data available from the literature were used to calibrate the unknown model parameters. The calibrated model was then validated by comparing its predictions with measured data from three different experimental human studies. RESULTS: The model predicted total DMSA plasma and urine concentrations measured in three healthy volunteers after ingestion of DMSA 10 mg/kg. The model was then validated by using data from three other published studies; it predicted concentrations within a factor of two, representing inter human variability. CONCLUSIONS: A simple kinetic model simulating the kinetics of DMSA in humans has been developed and validated. The interest of this model lies in the future potential to use it to predict blood lead concentrations in lead poisoned patients treated with DMSA. PMID- 27710181 TI - Double-Edged Sword: Women with Breast Cancer Caring for a Spouse with Cancer. AB - BACKGROUND: Experiences in caregiving may affect further coping with illness. The aim of this study was to assess mortality risk among women diagnosed with breast cancer while caring for a male spouse who had been diagnosed with cancer before or at the time of their own diagnosis. PATIENTS AND METHODS: We used a historical prospective study of a nationally representative cohort that was assessed by the Israeli Central Bureau of Statistics 1995 census and followed until 2011. The study population was divided into 2 * 2 groups (according to a positive/negative cancer history of the male spouse before the time of breast cancer diagnosis of the women X spouse alive/dead). The analyses were adjusted for age, ethnicity, breast cancer staging, and time of diagnosis. RESULTS: A total of 14,429 cases of breast cancer and 3,400 deaths were reported during the study period. Mortality was not mediated by the spouse's survival at the time of breast cancer diagnosis of the women. However, decreased risk of death was seen in women with a positive spouse history of cancer when the spouse was alive at the time of diagnosis in women who were diagnosed with breast cancer stages II and III (hazard ratio = 0.76, 95% CI: 0.59-0.98). CONCLUSION: Among a subset of women diagnosed with breast cancer, there is evidence of a significant protective association between a history of caregiving for cancer of a spouse who is alive at the time of self diagnosis and subsequent survival. Our findings support hypotheses concerning a positive experience of caregiving and emphasize the need to define the patient and the caregiver as an integrative "unit of care." PMID- 27710197 TI - Improved children's motor learning of the basketball free shooting pattern by associating subjective error estimation and extrinsic feedback. AB - This study aimed at assessing the interaction between subjective error estimation and frequency of extrinsic feedback in the learning of the basketball free shooting pattern by children. 10- to 12-year olds were assigned to 1 of 4 groups combining subjective error estimation and relative frequency of extrinsic feedback (33% * 100%). Analysis of performance was based on quality of movement pattern. Analysis showed superior learning of the group combining error estimation and 100% feedback frequency, both groups receiving feedback on 33% of trials achieved intermediate results, and the group combining no requirement of error estimation and 100% feedback frequency had the poorest learning. Our results show the benefit of subjective error estimation in association with high frequency of extrinsic feedback in children's motor learning of a sport motor pattern. PMID- 27710196 TI - Women's Contraceptive Preference-Use Mismatch. AB - BACKGROUND: Family planning research has not adequately addressed women's preferences for different contraceptive methods and whether women's contraceptive experiences match their preferences. METHODS: Data were drawn from the Women's Healthcare Experiences and Preferences Study, an Internet survey of 1,078 women aged 18-55 randomly sampled from a national probability panel. Survey items assessed women's preferences for contraceptive methods, match between methods preferred and used, and perceived reasons for mismatch. We estimated predictors of contraceptive preference with multinomial logistic regression models. RESULTS: Among women at risk for pregnancy who responded with their preferred method (n = 363), hormonal methods (non-LARC [long-acting reversible contraception]) were the most preferred method (34%), followed by no method (23%) and LARC (18%). Sociodemographic differences in contraception method preferences were noted (p values <0.05), generally with minority, married, and older women having higher rates of preferring less effective methods, compared to their counterparts. Thirty-six percent of women reported preference-use mismatch, with the majority preferring more effective methods than those they were using. Rates of match between preferred and usual methods were highest for LARC (76%), hormonal (non LARC) (65%), and no method (65%). The most common reasons for mismatch were cost/insurance (41%), lack of perceived/actual need (34%), and method-specific preference concerns (19%). CONCLUSION: While preference for effective contraception was common among this sample of women, we found substantial mismatch between preferred and usual methods, notably among women of lower socioeconomic status and women using less effective methods. Findings may have implications for patient-centered contraceptive interventions. PMID- 27710198 TI - Not strange but not true: self-reported interest in a topic increases false memory. AB - People are more likely to recall both true and false information that is consistent with their pre-existing stereotypes, schemata and desires. In addition, experts in a particular field are more likely to experience false memory in relation to their area of expertise. Here, we investigate whether level of interest, as distinct from level of knowledge, and in the absence of self professed expertise, is associated with increased false memory. 489 participants were asked to rank 7 topics from most to least interesting. They were then asked if they remembered the events described in four news items related to the topic they selected as the most interesting and four items related to the topic selected as least interesting. In each case, three of the events depicted had really happened and one was fictional. A high level of interest in a topic increased true memories for the topic and doubled the frequency of false memories, even after controlling for level of knowledge. We interpret the results in the context of the source-monitoring framework and suggest that false memories arise as a result of interference from existing information stored in domain related schemata. PMID- 27710199 TI - Overconfidence across the psychosis continuum: a calibration approach. AB - INTRODUCTION: An 'overconfidence in errors' bias has been consistently observed in people with schizophrenia relative to healthy controls, however, the bias is seldom found to be associated with delusional ideation. Using a more precise confidence-accuracy calibration measure of overconfidence, the present study aimed to explore whether the overconfidence bias is greater in people with higher delusional ideation. METHODS: A sample of 25 participants with schizophrenia and 50 non-clinical controls (25 high- and 25 low-delusion-prone) completed 30 difficult trivia questions (accuracy <75%); 15 'half-scale' items required participants to indicate their level of confidence for accuracy, and the remaining 'confidence-range' items asked participants to provide lower/upper bounds in which they were 80% confident the true answer lay within. RESULTS: There was a trend towards higher overconfidence for half-scale items in the schizophrenia and high-delusion-prone groups, which reached statistical significance for confidence-range items. However, accuracy was particularly low in the two delusional groups and a significant negative correlation between clinical delusional scores and overconfidence was observed for half-scale items within the schizophrenia group. Evidence in support of an association between overconfidence and delusional ideation was therefore mixed. CONCLUSIONS: Inflated confidence-accuracy miscalibration for the two delusional groups may be better explained by their greater unawareness of their underperformance, rather than representing genuinely inflated overconfidence in errors.

AB - The possible relationship between dietary cholesterol and cardiac outcomes has been scrutinized for decades. However, recent reviews of the literature have suggested that dietary cholesterol is not a nutrient of concern. Thus, we conducted a meta-analysis of egg intake (a significant contributor to dietary cholesterol) and risk of coronary heart disease (CHD) and stroke. A comprehensive literature search was conducted through August 2015 to identify prospective cohort studies that reported risk estimates for egg consumption in association with CHD or stroke. Random-effects meta-analysis was used to generate summary relative risk estimates (SRREs) for high vs low intake and stratified intake dose response analyses. Heterogeneity was examined in subgroups where sensitivity and meta regression analyses were conducted based on increasing egg intake. A 12% decreased risk (SRRE = 0.88, 95% confidence interval [CI], 0.81-0.97) of stroke was observed in the meta-analysis of 7 studies of egg intake (high vs low; generally 1/d vs <2/wk), with little heterogeneity (p-H = 0.37, I2 = 7.50). A nonstatistically significant SRRE of 0.97 (95% CI, 0.88-1.07, p-H = 0.67, I2 = 0.00) was observed in the meta-analysis of 7 studies of egg consumption and CHD. No clear dose-response trends were apparent in the stratified intake meta analyses or the meta regression analyses. Based on the results of this meta analysis, consumption of up to one egg daily may contribute to a decreased risk of total stroke, and daily egg intake does not appear to be associated with risk of CHD. Key Teaching Points: * The role of egg consumption in the risk of stroke and coronary heart disease has come under scrutiny over many years. * A comprehensive meta-analysis of prospective cohort studies that reported risk estimates for egg consumption in association with CHD or stroke was performed on the peer-reviewed epidemiologic literature through August 2015. * Overall, summary associations indicate that intake of up to 1 egg daily may be associated with reduced risk of total stroke. * Overall, summary associations show no clear association between egg intake and increased or decreased risk of CHD. * Eggs are a relatively low-cost and nutrient-dense whole food that provides a valuable source of protein, essential fatty acids, antioxidants, choline, vitamins, and minerals. PMID- 27710207 TI - Do emotional stimuli enhance or impede recall relative to neutral stimuli? An investigation of two "false memory" tasks. AB - Many eyewitness memory situations involve negative and distressing events; however, many studies investigating "false memory" phenomena use neutral stimuli only. The aim of the present study was to determine how both the Deese-Roediger McDermott (DRM) procedure and the Misinformation Effect Paradigm tasks were related to each other using distressing and neutral stimuli. Participants completed the DRM (with negative and neutral word lists) and viewed a distressing or neutral film. Misinformation for the film was introduced and memory was assessed. Film accuracy and misinformation susceptibility were found to be greater for those who viewed the distressing film relative to the neutral film. Accuracy responses on both tasks were related, however, susceptibility to the DRM illusion and Misinformation Effect were not. The misinformation findings support the Paradoxical Negative Emotion (PNE) hypothesis that negative stimuli will lead to remembering more accurate details but also greater likelihood of memory distortion. However, the PNE hypothesis was not supported for the DRM results. The findings also suggest that the DRM and Misinformation tasks are not equivalent and may have differences in underlying mechanisms. Future research should focus on more ecologically valid methods of assessing false memory. PMID- 27710209 TI - Explaining the persistence of false memories: a proposal based on associative activation and thematic extraction. AB - This study aimed to analyse the effect of retention intervals on associative and thematic false memories. Two experiments, using two types of critical items that were either associatively or thematically related to studied material, were conducted. In both experiments, one group of participants performed a recognition test immediately after the presentation of lists, and another group performed the task one week later. In Experiment 1, the recognition test consisted of pairs of items with four response alternatives (both items had been presented, only the left item had been presented, only the right item had been presented or none of the items had been presented). Critical items were also manipulated so that they were either presented in or absent from the list. In Experiment 2, a standard recognition test that differed in the mode of presentation was used: self-paced or speeded response. Both experiments showed that associative critical items were more recognised than thematic critical items in the immediate condition. However, whereas associative critical items decayed after a one-week delay, thematic critical items were similarly recognised at both retention intervals. The findings of the present study suggest that each type of process - associative and thematic - behave differently over time. PMID- 27710208 TI - Growth Characteristics of Alkhumra Hemorrhagic Fever Virus in Mammalian Cell Lines. AB - BACKGROUND: Alkhumra hemorrhagic fever virus (AHFV) is a flavivirus that was discovered in 1995 in Saudi Arabia. Clinical manifestations of AHFV infection include hemorrhagic fever, hepatitis, and encephalitis with a reported mortality rate as high as 25%. There are no published data on the growth characteristics of AHFV in mammalian cell lines. The objective of this study was to examine the ability of AHFV to grow and propagate in four of the commonly used mammalian cell culture lines and to determine the virus growth curve characteristics in each. MATERIALS AND METHODS: Human epidermoid carcinoma (HEp-2), LLC-MK2, Madin-Darby canine kidney (MDCK), and Vero cell lines were inoculated with AHFV. The virus production by each cell line was determined by growth curve studies. Mean titers were calculated and expressed as median tissue culture infective dose per mL (TCID50/mL). RESULTS: AHFV grew and propagated to variable titers in the employed cell lines. The highest mean titers were observed in the LLC-MK2, followed by the MDCK, Vero, and HEP-2, in descending order. CONCLUSIONS: The growth curve studies showed that AHFV can propagate in the four types of cell lines to variable titers. LLC-MK2 cells are superior to MDCK, Vero, and HEP-2 for propagation of AHFV. PMID- 27710211 TI - Data on survival of recent births as a source of child mortality estimates in the developing world: An assessment of census data. AB - In many less developed countries, household surveys collect full and summary birth histories to provide estimates of child mortality. However, full birth histories are expensive to collect and cannot provide precise estimates for small areas, and summary birth histories only provide past child mortality trends. A simple method that provides estimates for the most recent past uses questions about the survival of recent births in censuses or large household surveys. This study examines such data collected by 45 censuses and shows that on average they tend to underestimate under-5 mortality in comparison with alternative estimates, albeit with wide variations. In addition, the high non-sampling uncertainty in this approach precludes its use in providing robust estimates of child mortality at the country level. Given these findings, we suggest that questions about the survival of recent births to collect data on child mortality not be included in census questionnaires.

AB - OBJECTIVE: Goji fruit extracts, methanol (MGE) and hexane (HGE), were subjected to evaluation as potential source of phenolic antioxidants and antiradical activity. METHODS: Some phenolic compounds (gallic, protocatechuic, vanillic, chlorogenic, coumaric, caffeic and ferulic acid and catechin and rutin), vitamin C and carotenoids were identified and quantified by HPLC. Antioxidant activity was tested by measuring ability to scavenge DPPH and hydroxyl radicals. Also, reducing power of goji fruit extracts was determined. RESULTS: HPLC analysis results showed predominance of gallic acid (40.44 mg/g g.f). Vitamin C content in MGE was 716.91 mg vitC/100 g g.f. IC50DPPH. varied from 26.64 MUmolTEAC/g for HGE to 62.15 MUmolTEAC/g for MGE, while RP0.5 values varied from 952.23 MUmolTEAC/g for MGE to 1360.48 mg/mL for HGE. IC50.OH for MGE was 1844.01 MUmolTEAC/g. CONCLUSIONS: Our results support the use of goji fruits as rich sources of phytochemicals for further utilization in the food industry as supplements and functional food ingredients. PMID- 27710212 TI - Trends and correlates of single motherhood in Kenya: Results from the Demographic and Health Survey. AB - Single motherhood exposes women to poorer socioeconomic and health outcomes, which may also negatively impact child outcomes. The Demographic and Health Surveys of 1989, 1993, 1998, 2003, and 2009 were used to investigate trends over time and factors associated with single motherhood in Kenya. Urban residence, older age, and poorer economic status were associated with single motherhood over time. Women with more than one child, and those with children under 15 years living at home were less likely to be single mothers. As women become single mothers at different stages, targeted and supportive strategies are required to mitigate associated risks. PMID- 27710213 TI - Two novel pyrrolooxazole pigments formed by the Maillard reaction between glucose and threonine or serine. AB - Pyrrolothiazolate formed by the Maillard reaction between l-cysteine and d glucose has a pyrrolothiazole skeleton as a chromophore. We searched for a Maillard pigment having a pyrrolooxazole skeleton formed from l-threonine or l serine instead of l-cysteine in the presence of d-glucose. As a result, two novel yellow pigments, named pyrrolooxazolates A and B, were isolated from model solutions of the Maillard reaction containing l-threonine and d-glucose, and l serine and d-glucose, respectively, and identified as (2R,3S,7aS)-2,3,7,7a tetrahydro-6-hydroxy-2,5,7a-trimethyl-7-oxo-pyrrolo[2,1-b]oxazole-3-calboxylic acid and (3S,7aS)-2,3,7,7a-tetrahydro-6-hydroxy-5,7a-dimethyl-7-oxo-pyrrolo[2,1 b]oxazole-3-calboxylic acid by instrumental analyses. These compounds were pyrrolooxazole derivatives carrying a carboxy group, and showed the absorption maxima at 300-360 nm under acidic and neutral conditions and at 320-390 nm under alkaline conditions.

AB - This article analyzes print media interviews of Moscow lesbians in Moskovsky Komsomolets in 2004 and 2005 using qualitative content analysis. The qualitative content analysis shows recurring and consistent themes: (1) the stereotypes lesbians face; (2) public negativity toward same-sex relations and the impact on their families; (3) the expectations of heterosexuality and all that that entails; (4) the existence of lesbian-only spaces in Russia and the importance of those spaces; and (5) the complexities of navigating motherhood, previous heterosexual relationships, and current partnerships. Analysis of print media representations of female same-sex sexuality in a period of economic prosperity, popular culture visibility, and before restrictive laws were passed that suppress homosexuality adds to the previous literature on lesbianism in Russia. PMID- 27710239 TI - Free Radical-derived Oxysterols: Novel Adipokines Modulating Adipogenic Differentiation of Adipose Precursor Cells. AB - CONTEXT: Increased oxidative stress in adipose tissue emerges as an inducer of obesity-linked insulin resistance. Here we tested whether free-radical derived oxysterols are formed by, and accumulate in, human adipocytes. Moreover, we asked whether increased accumulation of oxysterols characterizes the adipose cells of obese patients with type 2 diabetes (T2D) (OBT2D) compared with lean, nondiabetic controls (CTRLs). Finally, we studied the effects of the free radical-derived oxysterols on adipogenic differentiation of adipose-derived stem cells (ASCs). MAIN OUTCOME MEASURES: Adipocytes and ASCs were isolated from sc abdominal adipose tissue biopsy in four OBT2D and four CTRL subjects. Oxysterols in adipocytes were detected by gas chromatography/mass spectrometry. The cellular and molecular effects of oxysterols were then evaluated on primary cultures of ASCs focusing on cell viability, adipogenic differentiation, and "canonical" WNT and MAPK signaling pathways. RESULTS: 7-ketocholesterol (7kappa-C) and 7beta hydroxycholesterol were unambiguously detected in adipocytes, which showed higher oxysterol accumulation (P < .01) in OBT2D, as compared with CTRL individuals. Notably, the accumulation of oxysterols in adipocytes was predicted by the adipose cell size of the donor (R2 = 0.582; P < .01). Challenging ASCs with free radical-derived type I (7kappa-C) and type II (5,6-Secosterol) oxysterols led to a time- and concentration-dependent decrease of cell viability. Meaningfully, at a non-toxic concentration (1MUM), these bioactive lipids hampered adipogenic differentiation of ASCs by sequential activation of WNT/beta-catenin, p38-MAPK, ERK1/2, and JNK signaling pathways. CONCLUSION: Free radical-derived oxysterols accumulate in the "diabetic" fat and may act as novel adipokines modulating the adipogenic potential of undifferentiated adipose precursor cells. PMID- 27710242 TI - Metabolic Fingerprints of Circulating IGF-1 and the IGF-1/IGFBP-3 Ratio: A Multifluid Metabolomics Study. AB - OBJECTIVE: IGF-1 is known for its various physiological and severe pathophysiological effects on human metabolism; however, underlying molecular mechanisms still remain unsolved. To reveal possible molecular mechanisms mediating these effects, for the first time, we associated serum IGF-1 levels with multifluid untargeted metabolomics data. METHODS: Plasma/urine samples of 995 nondiabetic participants of the Study of Health in Pomerania were characterized by mass spectrometry. Sex-specific linear regression analyses were performed to assess the association of IGF-1 and IGF-1/IGF binding protein 3 ratio with metabolites. Additionally, the predictive ability of the plasma and urine metabolome for IGF-1 was assessed by orthogonal partial least squares analyses. RESULTS AND CONCLUSIONS: We revealed a multifaceted image of associated metabolites with large sex differences. Confirming previous reports, we detected relations between IGF-1 and steroid hormones or related intermediates. Furthermore, various associated metabolites were previously mentioned regarding IGF-1-associated diseases, eg, betaine and cortisol in cardiovascular disease and metabolic syndrome, lipid disorders, and diabetes, or have previously been found to associate with differentiation and proliferation or mitochondrial functionality, eg, phospholipids. bradykinin, fatty acid derivatives, and cortisol, which were inversely associated with IGF-1, might establish a link of IGF-1 with inflammation. For the first time, we showed an association between IGF 1 and pipecolate, a metabolite linked to amino acid metabolism. Our study demonstrates that IGF-1 action on metabolism is tractable, even in healthy subjects, and that the findings provide a solid basis for further experimental/clinical investigation, eg, searching for inflammatory or cardiovascular disease- or metabolic syndrome-associated biomarkers and therapeutic targets. PMID- 27710240 TI - Differences in Mitochondrial Coupling Reveal a Novel Signature of Mitohormesis in Muscle of Healthy Individuals. AB - CONTEXT: Reduced mitochondrial coupling (ATP/O2 [P/O]) is associated with sedentariness and insulin resistance. Interpreting the physiological relevance of P/O measured in vitro is challenging. OBJECTIVE: To evaluate muscle mitochondrial function and associated transcriptional profiles in nonobese healthy individuals distinguished by their in vivo P/O. DESIGN: Individuals from an ancillary study of Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy phase 2 were assessed at baseline. SETTING: The study was performed at Pennington Biomedical Research Center. PARTICIPANTS: Forty-seven (18 males, 26-50 y of age) sedentary, healthy nonobese individuals were divided into 2 groups based on their in vivo P/O. INTERVENTION: None. Main Outcome(s): Body composition by dual-energy x-ray absorptiometry, in vivo mitochondrial function (P/O and maximal ATP synthetic capacity) by 31P-magnetic resonance spectroscopy and optical spectroscopy were measured. A muscle biopsy was performed to measure fiber type, transcriptional profiling (microarray), and protein expressions. RESULTS: No differences in body composition, peak aerobic capacity, type I fiber content, or mitochondrial DNA copy number were observed between the 2 groups. Compared with the uncoupled group (lower P/O), the coupled group (higher P/O) had higher rates of maximal ATP synthetic capacity (maximal ATP synthetic capacity, P < .01). Transcriptomics analyses revealed higher expressions of genes involved in mitochondrial remodeling and the oxidative stress response in the coupled group. A trend for higher mitonuclear protein imbalance (P = .06) and an elevated mitochondrial unfolded protein response (heat shock protein 60 protein; P = .004) were also identified in the coupled group. CONCLUSIONS: Higher muscle mitochondrial coupling is accompanied by an overall elevation in mitochondrial function, a novel transcriptional signature of oxidative stress and mitochondrial remodeling and indications of an mitochondrial unfolded protein response. PMID- 27710243 TI - ACAN Gene Mutations in Short Children Born SGA and Response to Growth Hormone Treatment. AB - Background: Some children born small for gestational age (SGA) show advanced bone age (BA) maturation during growth hormone (GH) treatment. ACAN gene mutations have been described in children with short stature and advanced BA. Objective: To determine the presence of ACAN gene mutations in short SGA children with advanced BA and assess the response to GH treatment. Methods: BA assessment in 290 GH treated SGA children. ACAN sequencing in 29 children with advanced BA >=0.5 years compared with calendar age. Results: Four of 29 SGA children with advanced BA had an ACAN gene mutation (13.8%). Mutations were related to additional characteristics: midface hypoplasia (P = 0.003), joint problems (P = 0.010), and broad great toes (P = 0.003). Children with one or fewer additional characteristic had no mutation. Of children with two additional characteristics, 50% had a mutation. Of children with three additional characteristics, 100% had a mutation. All GH-treated children with a mutation received gonadotropin-releasing hormone analog (GnRHa) treatment for 2 years from onset of puberty. At adult height, one girl was 5 cm taller than her mother and one boy was 8 cm taller than his father with the same ACAN gene mutation. Conclusion: This study expands the differential diagnosis of genetic variants in children born SGA and proposes a clinical scoring system for identifying subjects most likely to have an ACAN gene mutation. ACAN sequencing should be considered in children born SGA with persistent short stature, advanced BA, and midface hypoplasia, joint problems, or broad great toes. Our findings suggest that children with an ACAN gene mutation benefit from GH treatment with 2 years of GnRHa. PMID- 27710241 TI - Randomized Trial of Aromatase Inhibitors, Growth Hormone, or Combination in Pubertal Boys with Idiopathic, Short Stature. AB - CONTEXT: Growth of short children in puberty is limited by the effect of estrogen on epiphyseal fusion. OBJECTIVES: To compare: 1) the efficacy and safety of aromatase inhibitors (AIs) vs GH vs AI/GH on increasing adult height potential in pubertal boys with severe idiopathic short stature (ISS); and 2) differences in body composition among groups. DESIGN: Randomized three-arm open-label comparator. SETTING: Outpatient clinical research. PATIENTS: Seventy-six pubertal boys [mean (SE) age, 14.1 (0.1) years] with ISS [height SD score (SDS), -2.3 (0.0)]. INTERVENTION: Daily AIs (anastrozole or letrozole), GH, or AI/GH for 24 36 months. OUTCOMES: Anthropometry, bone ages, dual x-ray absorptiometry, spine x rays, hormones, safety labs. RESULTS: Height gain [mean (SE)] at 24 months was: AI, +14.0 (0.8) cm; GH, +17.1 (0.9) cm; AI/GH, +18.9 (0.8) cm (P < .0006, analysis of covariance). Height SDS was: AI, -1.73 (0.12); GH, -1.43 (0.14); AI/GH, -1.25 (0.12) (P < .0012). Those treated through 36 months grew more. Regardless of treatment duration, height SDS at near-final height [n = 71; age, 17.4 (0.2) years; bone age, 15.3 (0.1) years; height achieved, ~97.6%] was: AI, 1.4 (0.1); GH, -1.4 (0.2); AI/GH, -1.0 (0.1) (P = .06). Absolute height change was: AI, +18.2 (1.6) cm; GH, +20.6 (1.5) cm; AI/GH, +22.5 (1.4) cm (P = .01) (expected height gain at -2.0 height SDS, +13.0 cm). AI/GH had higher fat free mass accrual. Measures of bone health, safety labs, and adverse events were similar in all groups. Letrozole caused higher T and lower estradiol than anastrozole. CONCLUSIONS: Combination therapy with AI/GH increases height potential in pubertal boys with ISS more than GH and AI alone treated for 24-36 months with a strong safety profile.

PMID- 27710263 TI - Mechanisms of Hyperbilirubinemia During Peginterferon Lambda-1a Therapy for Chronic Hepatitis C Infection: A Retrospective Investigation. AB - The phase 2b EMERGE study compared the efficacy/safety of peginterferon lambda-1a (Lambda) and peginterferon alfa-2a (Alfa), both with ribavirin (RBV), for treatment of chronic hepatitis C virus (HCV) infection. A key safety finding was a higher frequency of hyperbilirubinemia with Lambda/RBV versus Alfa/RBV. To characterize mechanisms of hyperbilirubinemia associated with Lambda/RBV, we conducted a retrospective analysis of safety data from the HCV genotype 1 and genotype 4 cohort of the EMERGE study. Subjects were randomized to once-weekly Lambda (120/180/240 MUg) or Alfa (180 MUg), with daily RBV, for 48 weeks. Early onset Lambda/RBV-related hyperbilirubinemia events (6-12 weeks) resulted mostly from RBV-induced hemolysis evidenced by sustained reticulocytosis and a predominantly unconjugated pattern of hyperbilirubinemia. The higher hyperbilirubinemia frequency with Lambda/RBV versus Alfa/RBV was attributed to bone marrow suppression known to occur with Alfa but not Lambda. Late-onset (>12 weeks) Lambda/RBV-related hyperbilirubinemia events occurred most frequently with higher Lambda doses and were associated with increased levels of hepatic transaminase and direct bilirubin fractions compared with early events. This dual pattern of hyperbilirubinemia observed while on Lambda/RBV treatment is thought to be caused by exaggerated RBV-induced hemolysis in early-onset events compared with possible direct Lambda-induced hepatocellular toxicity in late-onset events. PMID- 27710244 TI - The Diagnosis and Management of Lipodystrophy Syndromes: A Multi-Society Practice Guideline. AB - OBJECTIVE: Lipodystrophy syndromes are extremely rare disorders of deficient body fat associated with potentially serious metabolic complications, including diabetes, hypertriglyceridemia, and steatohepatitis. Due to their rarity, most clinicians are not familiar with their diagnosis and management. This practice guideline summarizes the diagnosis and management of lipodystrophy syndromes not associated with HIV or injectable drugs. PARTICIPANTS: Seventeen participants were nominated by worldwide endocrine societies or selected by the committee as content experts. Funding was via an unrestricted educational grant from Astra Zeneca to the Pediatric Endocrine Society. Meetings were not open to the general public. EVIDENCE: A literature review was conducted by the committee. Recommendations of the committee were graded using the system of the American Heart Association. Expert opinion was used when published data were unavailable or scarce. CONSENSUS PROCESS: The guideline was drafted by committee members and reviewed, revised, and approved by the entire committee during group meetings. Contributing societies reviewed the document and provided approval. CONCLUSIONS: Lipodystrophy syndromes are heterogeneous and are diagnosed by clinical phenotype, supplemented by genetic testing in certain forms. Patients with most lipodystrophy syndromes should be screened for diabetes, dyslipidemia, and liver, kidney, and heart disease annually. Diet is essential for the management of metabolic complications of lipodystrophy. Metreleptin therapy is effective for metabolic complications in hypoleptinemic patients with generalized lipodystrophy and selected patients with partial lipodystrophy. Other treatments not specific for lipodystrophy may be helpful as well (eg, metformin for diabetes, and statins or fibrates for hyperlipidemia). Oral estrogens are contraindicated. PMID- 27710313 TI - Real-Time RT-PCR Assays for Detection and Genotyping of West Nile Virus Lineages Circulating in Africa. AB - West Nile virus (WNV) is an emerging arbovirus, circulating worldwide between birds and mosquitoes, which impacts human and animal health. Since the mid-1990s, WNV outbreaks have emerged in Europe and America and represent currently the primary cause of encephalitis in the United States. WNV exhibits a great genetic diversity with at least eight different lineages circulating in the world, and four (1, 2, Koutango, and putative new) are present in Africa. These different WNV lineages are not readily differentiated by serology, and thus, rapid molecular tools are required for diagnostic. We developed here real-time RT-PCR assays for detection and genotyping of African WNV lineages. The specificity of the assays was tested using other flaviviruses circulating in Africa. The sensitivity was determined by testing serial 10-fold dilutions of viruses and RNA standards. The assays provided good specificity and sensitivity and the analytical detection limit was 10 copies/reaction. The RT-PCR assays allowed the detection and genotyping of all WNV isolates in culture medium, human serum, and vertebrate tissues, as well as in field and experimental mosquito samples. Comparing the ratios of genome copy number/infectious virion (plaque-forming units), our study finally revealed new insight on the replication of these different WNV lineages in mosquito cells. Our RT-PCR assays are the first ones allowing the genotyping of all WNV African variants, and this may have important applications in surveillance and epidemiology in Africa and also for monitoring of their emergence in Europe and other continents. PMID- 27710430 TI - The isolation and functional identification on producing cellulase of Pseudomonas mendocina. AB - The straw can be degraded efficiently into humus by powerful enzymes from microorganisms, resulting in the accelerated circulation of N,P,K and other effective elements in ecological system. We isolated a strain through screening the straw degradation strains from natural humic straw in the low temperature area in northeast of china, which can produce cellulase efficiently. The strain was identified as Pseudomonas mendocina by using morphological, physiological, biochemical test, and molecular biological test, with the functional clarification on producing cellulase for Pseudomonas mendocina for the first time. The enzyme force constant Km and the maximum reaction rate (Vmax) of the strain were 0.3261 g/L and 0.1525 mg/(min.L) through the enzyme activity detection, and the molecular weight of the enzyme produced by the strain were 42.4 kD and 20.4 kD based on SDS-PAGE. The effects of various ecological factors such as temperature, pH and nematodes on the enzyme produced by the strain in the micro ecosystem in plant roots were evaluated. The result showed that the optimum temperature was 28 degrees C, and the best pH was 7.4~7.8, the impact heavy metal was Pb2+ and the enzyme activity and biomass of Pseudomonas mendocina increased the movement and predation of nematodes. PMID- 27710431 TI - Comparative analysis of protective effects of curcumin, curcumin-beta cyclodextrin nanoparticle and nanoliposomal curcumin on unsymmetrical dimethyl hydrazine poisoning in mice. AB - The aim of this study was to compare the protective effects of curcumin, curcumin beta-cyclodextrin nanoparticle curcumin (BCD-CUR) and nanoliposomal curcumin (NLC) on unsymmetrical dimethylhydrazine (UDMH) induced poison in mice. Curcumin, BCD-CUR, and NLC were prepared and their properties of zeta potential, particle size, encapsulation efficiency, and loading capacity were characterized. Eighty eight male ICR mice on normal chow diet were randomly divided into 11 groups, and intraperitoneally injected with UDMH alone, or together with different doses of curcumin, BCD-CUR or NLC daily for up to 10 d. Enzyme activities of serum alanine transaminase (ALT), aspartate aminotransferase (AST), and lactate dehydrogenase (LDH) were analyzed by fully-automatic analyzer and neurotransmitter levels were determined with high performance liquid chromatography (HPLC). 150 mg/kg curcumin treatment alone significantly reduced levels of serum ALT and LDH that were induced by UDMH and markedly increased level of gamma-amino butyric acid (GABA) that were reduced by UDMH in the hippocampus. 150 mg/kg BCD-CUR not only decreased significantly the increase of ALT, LDH and glutamate (Glu) but also recovered levels of AST and GABA. 150 mg/kg NLC recovered profoundly levels of AST and GABA while decreased remarkably the UDMH induced increase of ALT, LDH, Glu and 5-hydroxytryptamine (5-HT). In addition, treatments with all tested doses of NLC significantly reduced the UMDH induced dopamine (DA), the monoamine neurotransmitter. NLC had more profound protective effects against liver and central nervous system injury induced by UDMH than a suspension of BCD-CUR or curcumin did in mice. PMID- 27710432 TI - Improvement in degradability of 58s glass scaffolds by ZnO and beta-TCP modification. AB - 58s bioactive glass shows great potential for bone defects repair. However, at early repairing stage, the degradation rate of 58s glass is too fast due to the fast ion-exchange. At later repairing stage, the degradation rate of 58s glass is too slow due to the high dense mineral layer. In this work, Zinc oxide (ZnO) and beta-tricalcium phosphate (beta-TCP) were introduced into 58s glass bone scaffolds to improve the degradability. The results showed that ZnO could decrease the degradation rate and promote the stability of 58s glass at early repairing stage. Moreover, the presence of beta-TCP appeared to increase the degradation rate at a later stage of repairing. Furthermore, in vitro biocompatibility study, carried out using human osteoblast-like cells (MG63), demonstrated that ZnO and beta-TCP enhanced cell attachment and proliferation. The study provided a reference for further research in bone tissue engineering. PMID- 27710433 TI - Explicit vascular reconstruction based on adjacent vector projection. AB - Blood vascular reconstruction plays an important role in vessel disease diagnosis and prognosis, treatment planning and surgery. Based on adjacent vector projection, a simple and robust explicit algorithm is presented for vascular reconstruction. It generates the base mesh and utilizes the Loop algorithm for perceptual refinement by mesh subdivision. In the end, the reconstructed vascular tree is rendered for volumetric visualization and localization of vascular malformations. Experimental results on the Aneurisk database have validated the capacity of the proposed algorithm in generating smooth surface and natural transition of high tortuosity in real time, while on clinical cases has verified its accuracy on pinning vascular stenosis.

AB - A convenient and effective soft chemical method is presented for the synthesis of nano-scaled calcium citrate sheets. The preparation involved the precipitation of nano-calcium citrate by adding ethanol to reach the super saturation state of a solution containing calcium and citrate salts. The obtained nano-calcium citrate formed nanosheets, with the following dimensions: width of about 50~500 nm and thickness of about 8~30 nm. The results of the XRD analysis confirmed that the obtained sample is calcium citrate tetrahydrate, and the crystal degree decreased with an increase quantity of ethanol added. Animal experiments showed that the calcium citrate can promote the formation of new bone. PMID- 27710435 TI - Nanoindentation investigation of the stress exponent for the creep of dung beetle (Copris ochus Motschulsky) cuticle. AB - ABSTACT With the rapid development of bionic science, especially the progress that has been made in the fields of biomaterials and biomimetics, there is now great interest in the surface and internal mechanical properties of biological materials at the micro- and nanoscale. The study of micro- and nanoscale biomaterial mechanical properties could enable interdisciplinary applications in materials science, biological science and bionic science. Dung beetle (Copris ochus Motschulsky) cuticle is a viscoelastic material that is both viscous and flexible via elastic deformation under external forces; where stress sigma, strain epsilon and elastic modulus E are related in the following way: sigma = Eepsilon. In addition, as sigma is related to the rate of strain, time is also a factor. The stress-strain relationships of various parts of dung beetle cuticle were investigated in this paper. As time increased, the stress and strain of the material were found to decrease and increase, respectively, indicating that when the material was indented for a certain period, the interaction force between the indenter and the material gradually achieved a state of dynamic equilibrium. However, strain continued to occur until reaching a point of equilibrium because of the creep phenomenon. The stress-strain curves showed a strong character in each holding time condition: the longer the holding time, the more flattened the stress-strain curve. These findings will be useful in the advanced design of strong, lightweight, and biomimetic composites.

AB - OBJECTIVE: The objective of this study was to compare the chronic effects of different whey protein forms on body composition and performance when supplemented with resistance training. METHODS: Resistance-trained men (N = 56, 21.4 +/- 0.4 years, 79.5 +/- 1.0 kg) participated in an 8-week resistance training regimen (2 upper-body sessions and 2 lower-body sessions per week) and received one of 4 double-blinded treatments: 30 g/serving carbohydrate placebo (PLA) or 30 g/serving protein from either (a) 80% whey protein concentrate (WPC), (b) high-lactoferrin-containing WPC (WPC-L), or (c) extensively hydrolyzed WPC (WPH). All subjects consumed 2 servings of treatment per day; specifically, once immediately before and after training and between meals on nontraining days. Blood collection, one repetition maximum (1RM) testing for bench press and hack squat, and body composition assessment using dual-energy x-ray absorptiometry (DXA) occurred prior to training and 48 hours following the last training session. RESULTS: Total body skeletal muscle mass increased in all groups (p < 0.0125). There were similar between-group increases in upper-body (4%-7%, analysis of covariance [ANCOVA] interaction p = 0.73) and lower-body (24%-35%, ANCOVA interaction p = 0.85) 1RM strength following the intervention. Remarkably, WPH reduced fat mass (-6%), which was significantly different from PLA (+4.4%, p < 0.0125). No time or between-group differences were present for serum markers of health, metabolism, or muscle damage, with the exception of blood urea nitrogen being significantly lower for WPH than WPC (p < 0.05) following the intervention. CONCLUSIONS: WPH may augment fat loss but did not provide any other advantages when used in combination with resistance training. More mechanistic research is needed to examine how WPH affects adipose tissue physiology. PMID- 27710437 TI - Influence of football size on kicking performance in youth Australian rules footballers. AB - In Australian rules football structured increases in ball size during development end with the transition to the Size 5 (adult) ball at the Under-15 age group. This study assessed changes in kick technique and performance in experienced junior performers when using Size 4 and 5 Australian rules footballs. Participants (n = 22, 13.77 +/- 0.61 years) performed drop punt kicks in 2 representative tasks; a Decision-Making Test (DMT) (n = 14) and Set-Shot Test (SST) (n = 14 + 8). Results indicate participants sustained their level of kick performance (accuracy and quality of ball spin) in both tests when using a Size 5 football. Sustained kick performance in the DMT primarily resulted from adaptations to time-point technical measures at ball release. No significant differences were detected for technical measures between ball sizes in the SST. A dynamic kicking task (DMT) in combination with ball size manipulation may have placed greater demand on skill execution in comparison to a self-paced kicking task (SST). Results provide initial support for the utility of challenging representative dynamic and self-paced tasks, such as the DMT and SST used here for Australian football, for skill testing and practice in sport. PMID- 27710596 TI - The Effect of Quercetin on Inflammatory Factors and Clinical Symptoms in Women with Rheumatoid Arthritis: A Double-Blind, Randomized Controlled Trial. AB - OBJECTIVE: Previous studies have shown that the bioflavonoid quercetin has anti inflammatory and anti-nociceptive effects. We investigated the effect of quercetin supplementation on inflammation, disease severity, and clinical symptoms in women with rheumatoid arthritis (RA). METHODS: The present study was a randomized, double-blind, placebo-controlled clinical trial in which 50 women with RA were allocated into a quercetin (500 mg/day) or placebo group for 8 weeks. Plasma levels of high-sensitivity tumor necrosis factor-alpha (hs TNFalpha), erythrocyte sedimentation rate (ESR), clinical symptoms including early morning stiffness (EMS), morning and after-activity pain, and tender (TSC) and swollen joint counts (SJC) were determined. Disease activity and functional disability were assessed by Disease Activity Score 28 (DAS-28), physician global assessment (PGA), and a health assessment questionnaire (HAQ) at the beginning and end of the study. RESULTS: Quercetin supplementation for 8 weeks significantly reduced EMS, morning pain, and after-activity pain (p < 0.05). DAS 28 and HAQ scores decreased in the quercetin group compared to placebo and the number of patients with active disease significantly decreased in the quercetin group. Plasma hs-TNFalpha level was significantly reduced in the quercetin group compared to placebo (p < 0.05). There were no significant differences in TJC and SJC between groups but TJC significantly decreased in the quercetin group after the intervention. Supplementation had an effect on ESR but it was not significant (p > 0.05). CONCLUSIONS: Five hundred milligrams per day quercetin supplementation for 8 weeks resulted in significant improvements in clinical symptoms, disease activity, hs-TNFalpha, and HAQ in women with RA.

AB - AIM: To assess the changes in interviewees' and interviewers' perceptions and experiences of national recruitment and a multi-station interview (MSI) for the selection of Orthodontic Specialty Registrars to UK training programmes from 2012 to 2014. DESIGN: Questionnaire-based longitudinal survey. SETTING: Interviews for selection of Orthodontic Specialty Registrars (StRs) held at London Deanery, London, UK. METHODS: Interviewees and interviewers completed an anonymous questionnaire comprising of 17 and 26 questions, respectively. RESULTS: Interviewees: The number, age (p = 0.29) and time since qualification (p = 0.90) increased slightly over the 3 years but these changes were not statistically significant. The proportion of females (p = 0.32) and those with a UK primary dental qualification (p = 0.52) varied slightly but the variation was not statistically significant. The proportion that had experience of the MSI format increased significantly over the 3 years (p < 0.01). More than 75% were positive about the organization, experience and fairness of the MSI interview format. Interviewers: The age (p = 0.54), time since being a consultant (p = 0.90), proportion of females (p = 0.43) and those favouring the MSI format (p = 0.29) varied slightly but this was not statistically significant. More than 75% were positive about the organization, experience and fairness of the MSI format. More than 90% of interviewers thought that the process selected the best candidates, was fair and that more than one assessor was required at each station. CONCLUSIONS: Interviewees were consistently very positive about the organization and fairness of the MSI format. Interviewers were consistently very positive about the selection of candidates, fairness and conduct of the MSIs.

AB - Cr speciation in Cr-sorbing washed incinerator fly ash (IFA) after heating up to 1100 degrees C is temperature dependent. Higher temperature leads to a greater level of chemical reduction of Cr(VI) that is considerably more toxic than Cr(III). Most Cr(VI) sorbed washed IFA is effectively transformed into Cr(III) after heating to 1100 degrees C for 2 h, as indicated by the disappearance of hexavalent pre-edge peak of Cr K-edge X-ray absorption near edge structure (XANES) spectrum. After heating the Cr-sorbing IFA to 100 degrees C and 500 degrees C for 2 h, water-soluble CaCrO4 is determined to be the principal Cr species due to the chemical reaction between the sorbed Cr(VI) and CaO components of washed fly ash, based on the comparison between sample and reference XANES spectra. Replacing half of the washed fly ash with kaolin could effectively reduce all Cr(VI) after heating to ? 900 degrees C for 2 h. PMID- 27710701 TI - The Consumption of Breakfast, Fish and/or Caffeine does not Predict Study Progress in Adult Distance Education. AB - Consumption of breakfast, fish, or caffeine are each separately often investigated in relation to learning performance in traditional education, but not in distance education (DE). The objective of this study was to investigate whether the relations between the consumption of breakfast, fish, and/or caffeine on the one hand and learning performance on the other are also found in DE students. This population is different from traditional students and characterized by a different profile in terms of age, personal and work responsibilities as well as other demographics. In an observational longitudinal study, the consumption of breakfast, fish, and caffeine of 1157 DE students (18 76 years old, mean 35.8+/-11.1 years) was used to predict learning performance using multiple regression analysis. In an online digital survey, university students provided information about their consumption of these nutritional measures and on important covariates. Learning performance, measured as study progress (i.e., the number of successfully completed modules), was evaluated objectively after 14 months. Results showed that adding the consumption of breakfast, fish, and caffeine to the covariate model did not fit the data better, chi2 (3, N = 1155) = 3.287, p = 0.35. This means that neither the consumption of breakfast nor fish nor caffeine predicted study progress in adults participating in DE. This study is important as it is the first to report on these relations in this specific age group and educational setting, which is increasingly important due to the increased preference for this type of education. PMID- 27710700 TI - Long-term effects of back extensor strengthening exercises on quality of life in women with osteoporosis. AB - The aim of the present study was to evaluate the long-term effect of back extensor strengthening exercises on health-related quality of life (QOL) in women with osteoporosis. In this randomized clinical trial, 183 women with osteoporosis were treated with pharmacotherapy and weight-bearing and balance-training exercises. The case group additionally performed back extensor exercises at home. Patients filled out the Persian version of the Short Form (SF-36) QOL questionnaire at baseline and 6 months post treatment. At the end, all physical and mental parameters of the SF-36 questionnaire improved significantly in the case group, except for one subscale of mental health, compared to the control group. In the control group, only some physical health dimensions (bodily pain, role limitation, physical function, vitality), and mental health status as a mental health subscale improved. In conclusion, considering a major impact of back extensor exercises on improving QOL in women with osteoporosis over the long term, these exercises should be prescribed in routine management of these patients. PMID- 27710704 TI - Effect of Radiofrequency Radiation on Human Hematopoietic Stem Cells. AB - Exposure to electromagnetic fields in the radiofrequency range is ubiquitous, mainly due to the worldwide use of mobile communication devices. With improving technologies and affordability, the number of cell phone subscriptions continues to increase. Therefore, the potential effect on biological systems at low intensity radiation levels is of great interest. While a number of studies have been performed to investigate this issue, there has been no consensus reached based on the results. The goal of this study was to elucidate the extent to which cells of the hematopoietic system, particularly human hematopoietic stem cells (HSC), were affected by mobile phone radiation. We irradiated HSC and HL-60 cells at frequencies used in the major technologies, GSM (900 MHz), UMTS (1,950 MHz) and LTE (2,535 MHz) for a short period (4 h) and a long period (20 h/66 h), and with five different intensities ranging from 0 to 4 W/kg specific absorption rate (SAR). Studied end points included apoptosis, oxidative stress, cell cycle, DNA damage and DNA repair. In all but one of these end points, we detected no clear effect of mobile phone radiation; the only alteration was found when quantifying DNA damage. Exposure of HSC to the GSM modulation for 4 h caused a small but statistically significant decrease in DNA damage compared to sham exposure. To our knowledge, this is the first published study in which putative effects (e.g., genotoxicity or influence on apoptosis rate) of radiofrequency radiation were investigated in HSC. Radiofrequency electromagnetic fields did not affect cells of the hematopoietic system, in particular HSC, under the given experimental conditions. PMID- 27710702 TI - State-of-the-Art Advances in Radiation Biodosimetry for Mass Casualty Events Involving Radiation Exposure. AB - With the possibility of large-scale terrorist attacks around the world, the need for modeling and development of new medical countermeasures for potential future chemical, biological, radiological and nuclear (CBRN) has been well established. Project Bioshield, initiated in 2004, provided a framework to develop and expedite research in the field of CBRN exposures. To respond to large-scale population exposures from a nuclear event or radiation dispersal device (RDD), new methods for determining received dose using biological modeling became necessary. The field of biodosimetry has advanced significantly beyond this original initiative, with expansion into the fields of genomics, proteomics, metabolomics and transcriptomics. Studies are ongoing to evaluate the use of lymphocyte kinetics for dose assessment, as well as the development of field deployable EPR technology. In addition, expansion of traditional cytogenetic assessment methods through the use of automated platforms and the development of laboratory surge capacity networks have helped to advance our biodefense preparedness. In this review of the latest advances in the field of biodosimetry we evaluate our progress and identify areas that still need to be addressed to achieve true field-deployment readiness. PMID- 27710703 TI - Total-Body Irradiation Exacerbates Dissemination of Cutaneous Candida Albicans Infection. AB - Exposure to radiation, particularly a large or total-body dose, weakens the immune system through loss of bone marrow precursor cells, as well as diminished populations of circulating and tissue-resident immune cells. One such population is the skin-resident immune cells. Changes in the skin environment can be of particular importance as the skin is also host to a number of commensal organisms, including Candida albicans , a species of fungus that causes opportunistic infections in immunocompromised patients. In a previous study, we found that a 6 Gy sublethal dose of radiation in mice caused a reduction of cutaneous dendritic cells, indicating that the skin may have a poorer response to infection after irradiation. In this study, the same 6 Gy sublethal radiation dose led to a weakened response to a C. ablicans cutaneous infection, which resulted in systemic dissemination from the ear skin to the kidneys. However, this impaired response was mitigated through the use of interleukin-12 (IL-12) administered to the skin after irradiation. Concomitantly with this loss of local control of infection, we also observed a reduction of CD4+ and CD8+ T cells in the skin, as well as the reduced expression of IFN-gamma, CXCL9 and IL-9, which influence T-cell infiltration and function in infected skin. These changes suggest a mechanism by which an impaired immune environment in the skin after a sublethal dose of radiation increases susceptibility to an opportunistic fungal infection. Thus, in the event of radiation exposure, it is important to include antifungal agents, or possibly IL-12, in the treatment regimen, particularly if wounds are involved that result in loss of the skin's physical barrier function. PMID- 27710705 TI - Pomegranate peel extract attenuates oxidative stress by decreasing coronary angiotensin-converting enzyme (ACE) activity in hypertensive female rats. AB - Based on the antioxidant properties of pomegranate, this study was designed to investigate the effects of pomegranate peel extract on damage associated with hypertension and aging in a spontaneously hypertensive rat (SHR) model. The influence of pomegranate consumption was examined on systolic blood pressure (SBP), angiotensin-converting enzyme (ACE) coronary activity, oxidative stress, and vascular morphology. Four- or 28-wk-old SHR model rats were treated for 30 d, with terminal experimental animal age being 8 and 32 wk, respectively, with either pomegranate extract (SHR-PG) or filtered water (SHR). Data showed significant reduction in SBP and coronary ACE activity in both age groups. The levels of superoxide anion, a measure of oxidative stress, were significantly lower in animals in the SHR-PG group compared to SHR alone. Coronary morphology demonstrated total increases in vascular wall areas were in the SHR group, and pomegranate peel extract diminished this effect. Pomegranate peel extract consumption conferred protection against hypertension in the SHR model. This finding was demonstrated by marked reduction in coronary ACE activity, oxidative stress, and vascular remodelling. In addition, treatment was able to reduce SBP in both groups. Evidence indicates that the use of pomegranate peel extract may prove beneficial in alleviating coronary heart disease. PMID- 27710762 TI - The Effects of Cannabis on Inpatient Agitation, Aggression, and Length of Stay. AB - OBJECTIVE: This study examines the association between cannabis use and the hospital course of patients admitted to the psychiatric inpatient unit with a diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder. Many confounding variables potentially contribute to the clinical presentation of hospitalized patients in the psychiatric unit. Illicit drug use, in particular, has been associated with acute agitation, and questions can be raised as to what lasting effects drug use prior to admission may have throughout a patient's hospital stay. METHODS: Subjects with a discharge diagnosis of bipolar disorder, schizophrenia, schizoaffective disorder, or psychosis not otherwise specified (N = 201) were retrospectively identified, and those with positive results of urine drug screen for cannabis on admission were compared to negative counterparts. Agitation and aggression were measured using an adaptation of the Excited Component of the Positive and Negative Syndrome Scale (PANSS-EC). These markers were also quantified by comparing charted episodes of restraint and seclusion and administration of as needed medications, such as benzodiazepines and antipsychotics. RESULTS: Positive urine drug screen results for cannabis was correlated with young (p = .001) males (p = .003) with bipolar disorder (p = .009) exhibiting active manic symptoms (p = .003) at the time of admission. Cannabis use was further associated with a shorter length of stay (p = .008), agitation triggering adapted PANSS-EC nursing assessments (p = .029), and oral medications as needed (p = .002) for agitation. CONCLUSIONS: Cannabis use, as defined by positive urine drug screen results, was more common in patients with bipolar disorder and was accompanied by a higher incidence of inpatient agitation. Although these patients also had short hospital lengths of stay, there was no clear relationship between level of agitation and length of stay across all patient groups. One possible explanation for patients with bipolar disorder experiencing short lengths of stay is that their source of agitation may be more closely related to a complex effect of cannabis use rather than a sole etiology of mental illness. Inpatient clinicians should be aware of patient cannabis use proximate to admission. PMID- 27710763 TI - Disparities in Who Receives Weight-Loss Advice From a Health Care Provider: Does Income Make a Difference? AB - INTRODUCTION: The US Preventive Services Task Force recommends that all patients be screened for obesity and, if needed, be provided weight-loss advice. However, the prevalence of such advice is low and varies by patient demographics. This study aimed to describe the determinants of receiving weight-loss advice among a sample with a high proportion of low-income, racial/ethnic minority individuals. METHODS: Data were collected from a telephone survey of 1,708 households in 2009 and 2010 in 5 cities in New Jersey. Analyses were limited to 1,109 overweight or obese adults. Multivariate logistic regression determined the association of participants' characteristics with receiving weight-loss advice from their health care provider. Two models were used to determine differences by income and insurance status. RESULTS: Of all overweight or obese respondents, 35% reported receiving advice to lose weight. Receiving advice was significantly associated with income in multivariate analysis. Compared with those with an income at or below 100% of the federal poverty level (FPL), those within 200% to 399% of the FPL had 1.60 higher odds of receiving advice (P = .02), and those with an income of 400% or more of the FPL had 1.73 higher odds of receiving advice (P = .03). The strength of the association did not change after adjusting for health insurance. CONCLUSION: Income is a significant predictor of whether or not overweight or obese adults receive weight-loss advice after adjustment for demographic variables, health status, and insurance status. Further work is needed to examine why disparities exist in who receives weight-loss advice. Health care providers should provide weight-loss advice to all patients, regardless of income. PMID- 27710764 TI - Absenteeism and Employer Costs Associated With Chronic Diseases and Health Risk Factors in the US Workforce. AB - INTRODUCTION: Employers may incur costs related to absenteeism among employees who have chronic diseases or unhealthy behaviors. We examined the association between employee absenteeism and 5 conditions: 3 risk factors (smoking, physical inactivity, and obesity) and 2 chronic diseases (hypertension and diabetes). METHODS: We identified 5 chronic diseases or risk factors from 2 data sources: MarketScan Health Risk Assessment and the Medical Expenditure Panel Survey (MEPS). Absenteeism was measured as the number of workdays missed because of sickness or injury. We used zero-inflated Poisson regression to estimate excess absenteeism as the difference in the number of days missed from work by those who reported having a risk factor or chronic disease and those who did not. Covariates included demographics (eg, age, education, sex) and employment variables (eg, industry, union membership). We quantified absenteeism costs in 2011 and adjusted them to reflect growth in employment costs to 2015 dollars. Finally, we estimated absenteeism costs for a hypothetical small employer (100 employees) and a hypothetical large employer (1,000 employees). RESULTS: Absenteeism estimates ranged from 1 to 2 days per individual per year depending on the risk factor or chronic disease. Except for the physical inactivity and obesity estimates, disease- and risk-factor-specific estimates were similar in MEPS and MarketScan. Absenteeism increased with the number of risk factors or diseases reported. Nationally, each risk factor or disease was associated with annual absenteeism costs greater than $2 billion. Absenteeism costs ranged from $16 to $81 (small employer) and $17 to $286 (large employer) per employee per year. CONCLUSION: Absenteeism costs associated with chronic diseases and health risk factors can be substantial. Employers may incur these costs through lower productivity, and employees could incur costs through lower wages. PMID- 27710765 TI - Divergent Perceptions of Barriers to Diabetic Retinopathy Screening Among Patients and Care Providers, Los Angeles, California, 2014-2015. AB - INTRODUCTION: Despite availability of screening for diabetic retinopathy, testing is underused by many low-income and racial/ethnic minority patients with diabetes. We examined perceived barriers to diabetic retinopathy screening among low-income patients and their health care providers and provider staffers. METHODS: We collected survey data from 101 patients with diabetes and 44 providers and staffers at a safety-net clinic where annual diabetic retinopathy screening rates were low. Barriers specified in the survey were derived from the literature. RESULTS: Patients surveyed (mean [standard deviation] age, 54.0 [7.7] y; 41% were male) were primarily Hispanics (70%) and African Americans (27%) of low socioeconomic status. Overall, 55% of patients received diabetic retinopathy screening in the previous year. Patients who could not explain why this screening is needed reported more barriers than patients who could (2.5 vs 1.4 barriers, P = .02). Fewer patients reported that they experienced barriers such as transportation (15%), language issues (15%), cultural beliefs or myths (4%), denial (8%), and fear (5%), which providers and staffers considered very or extremely important (all P < .001). Financial burdens (26%) and depression (22%) were most commonly reported by patients as barriers, yet providers and staffers did not rate these barriers as important, P < .001. CONCLUSION: Patients and health care providers had markedly divergent perceptions of barriers to diabetic retinopathy screening. Patients with poor understanding of the need for screening were more likely to report such barriers. These results suggest a need for active community engagement to find key elements for education programs and other interventions to increase rates of diabetic retinopathy screening, particularly among low-income, minority populations. PMID- 27710766 TI - An event map of memory space in the hippocampus. AB - The hippocampus has long been implicated in both episodic and spatial memory, however these mnemonic functions have been traditionally investigated in separate research strands. Theoretical accounts and rodent data suggest a common mechanism for spatial and episodic memory in the hippocampus by providing an abstract and flexible representation of the external world. Here, we monitor the de novo formation of such a representation of space and time in humans using fMRI. After learning spatio-temporal trajectories in a large-scale virtual city, subject specific neural similarity in the hippocampus scaled with the remembered proximity of events in space and time. Crucially, the structure of the entire spatio-temporal network was reflected in neural patterns. Our results provide evidence for a common coding mechanism underlying spatial and temporal aspects of episodic memory in the hippocampus and shed new light on its role in interleaving multiple episodes in a neural event map of memory space. PMID- 27710767 TI - Unique membrane properties and enhanced signal processing in human neocortical neurons. AB - The advanced cognitive capabilities of the human brain are often attributed to our recently evolved neocortex. However, it is not known whether the basic building blocks of the human neocortex, the pyramidal neurons, possess unique biophysical properties that might impact on cortical computations. Here we show that layer 2/3 pyramidal neurons from human temporal cortex (HL2/3 PCs) have a specific membrane capacitance (Cm) of ~0.5 uF/cm2, half of the commonly accepted 'universal' value (~1 uF/cm2) for biological membranes. This finding was predicted by fitting in vitro voltage transients to theoretical transients then validated by direct measurement of Cm in nucleated patch experiments. Models of 3D reconstructed HL2/3 PCs demonstrated that such low Cm value significantly enhances both synaptic charge-transfer from dendrites to soma and spike propagation along the axon. This is the first demonstration that human cortical neurons have distinctive membrane properties, suggesting important implications for signal processing in human neocortex. PMID- 27710768 TI - Active suppression of a leaf meristem orchestrates determinate leaf growth. AB - Leaves are flat determinate organs derived from indeterminate shoot apical meristems. The presence of a specific leaf meristem is debated, as anatomical features typical of meristems are not present in leaves. Here we demonstrate that multiple NGATHA (NGA) and CINCINNATA-class-TCP (CIN-TCP) transcription factors act redundantly, shortly after leaf initiation, to gradually restrict the activity of a leaf meristem in Arabidopsis thaliana to marginal and basal domains, and that their absence confers persistent marginal growth to leaves, cotyledons and floral organs. Following primordia initiation, the restriction of the broadly acting leaf meristem to the margins is mediated by the juxtaposition of adaxial and abaxial domains and maintained by WOX homeobox transcription factors, whereas other marginal elaboration genes are dispensable for its maintenance. This genetic framework parallels the morphogenetic program of shoot apical meristems and may represent a relic of an ancestral shoot system from which seed plant leaves evolved. PMID- 27710769 TI - The isolated voltage sensing domain of the Shaker potassium channel forms a voltage-gated cation channel. AB - Domains in macromolecular complexes are often considered structurally and functionally conserved while energetically coupled to each other. In the modular voltage-gated ion channels the central ion-conducting pore is surrounded by four voltage sensing domains (VSDs). Here, the energetic coupling is mediated by interactions between the S4-S5 linker, covalently linking the domains, and the proximal C-terminus. In order to characterize the intrinsic gating of the voltage sensing domain in the absence of the pore domain, the Shaker Kv channel was truncated after the fourth transmembrane helix S4 (Shaker-iVSD). Shaker-iVSD showed significantly altered gating kinetics and formed a cation-selective ion channel with a strong preference for protons. Ion conduction in Shaker-iVSD developed despite identical primary sequence, indicating an allosteric influence of the pore domain. Shaker-iVSD also displays pronounced 'relaxation'. Closing of the pore correlates with entry into relaxation suggesting that the two processes are energetically related. PMID- 27710771 TI - Modelling the impact of water activity and fat content of dry-cured ham on the reduction of Salmonella enterica by high pressure processing. AB - This work aimed to quantify the impact of aw and fat content of dry-cured ham on the Log reduction of Salmonella enterica by high pressure (HP). Dry-cured ham with adjusted aw (0.86-0.96) and fat content (10-50%) was inoculated with S. enterica and pressurised (347-852MPa, 5min/15 degrees C), following a Central Composite Design. Polynomial regression indicated a significant impact of pressure and aw on S. enterica HP-lethality. By lowering aw a clear piezoprotection was observed. At low aw (0.88) the S. enterica reduction was little affected by increasing pressure (e.g. 2.3 to 3.2 Logs at 450 to 750MPa, respectively). At the highest aw the estimated inactivation ranged from 3.3 to 8.9 Logs at 450 to 750MPa, respectively. No significant piezoprotective effect on S. enterica was recorded by the fat content. The relevance of food characteristics on the HP-lethality of S. enterica indicate the need to validate the HP effectiveness on the specific product. PMID- 27710772 TI - Impact of high oxygen and vacuum retail ready packaging formats on lamb loin and topside eating quality. AB - Lamb steaks from semimembranosus (SM) and longissimus thoracis et lumborum (LTL) muscles were allocated to three different packaging treatments - Darfresh(r) vacuum skin packaging (VSP), Darfresh(r) Bloom packaging (80% O2:20% CO2; Hi-Ox DB) or high oxygen modified atmosphere packaging (80% O2:20% CO2; Hi-Ox-MAP) - and stored in simulated retail display for 5 or 10days and then subjected to consumer sensory and chemical analyses. Hi-Ox-MAP and Hi-Ox-DB samples had lower tenderness, flavor, juiciness and overall liking scores and higher TBARS values, compared to VSP. Hi-Ox-MAP samples deteriorated in juiciness and flavor between 5 and 10days. Hi-Ox-MAP LTL samples had a lower myofibrillar fragmentation index, consistent with reduced proteolysis, although desmin proteolysis and desmin and troponin-T cross-linking were not influenced by packaging. The LTL exhibited greater desmin degradation and reduced desmin cross-linking relative to the SM, supporting the higher tenderness scores in this muscle. Direct packaging of lamb into retail ready VSP may provide the sheepmeat industry with greater flexibility while increasing consumer satisfaction. PMID- 27710770 TI - Atomic mutagenesis in ion channels with engineered stoichiometry. AB - C-type inactivation of potassium channels fine-tunes the electrical signaling in excitable cells through an internal timing mechanism that is mediated by a hydrogen bond network in the channels' selectively filter. Previously, we used nonsense suppression to highlight the role of the conserved Trp434-Asp447 indole hydrogen bond in Shaker potassium channels with a non-hydrogen bonding homologue of tryptophan, Ind (Pless et al., 2013). Here, molecular dynamics simulations indicate that the Trp434Ind hydrogen bonding partner, Asp447, unexpectedly 'flips out' towards the extracellular environment, allowing water to penetrate the space behind the selectivity filter while simultaneously reducing the local negative electrostatic charge. Additionally, a protein engineering approach is presented whereby split intein sequences are flanked by endoplasmic reticulum retention/retrieval motifs (ERret) are incorporated into the N- or C- termini of Shaker monomers or within sodium channels two-domain fragments. This system enabled stoichiometric control of Shaker monomers and the encoding of multiple amino acids within a channel tetramer. PMID- 27710773 TI - Bioactive peptides in beef: Endogenous generation through postmortem aging. AB - The present research was performed to investigate endogenous release of bioactive peptides in beef during postmortem aging times (1, 10 and 20days). Gradually decreased Warner-Bratzler shear force (WBSF) values of longissimus thoracis (LT) and semitendinosus (ST) muscles were observed and the degradation of structural proteins and collagen led to release of low-molecular weight (<3kDa) peptides. These peptides exhibited 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity, ACE- and renin-inhibitory activities. The peptide sequences were identified by liquid chromatography-electrospray ionization-mass spectrometry (LC ESI-MS). In silico analysis (PeptideRanker and BIOPEP) of their bioactivity potentials demonstrated peptides with the predicted bioactivity scores (>0.8) as well as collagen peptides with bioactivity scores (0.6-0.8). The present findings provide insights on development of healthy beef through postmortem aging at 4 degrees C. PMID- 27710774 TI - The release of dormancy, a wake-up call for seeds to germinate. AB - Seed dormancy determines the timing of germination, thereby contributing to successful seedling establishment and plant fitness. The induction and release of dormancy are controlled by various regulators like plant hormones and dormancy proteins. The relative strengths of these regulators are influenced by environmental factors during seed maturation and storage. In the last few years additional processes have been identified to be involved in the release of dormancy during seed storage with an important role for non-enzymatic oxidative reactions. However, the relations between the different dormancy regulators are not fully understood yet. Finally, all accumulated information will be processed in the seed during early seed imbibition and lead to the decision to germinate or not. PMID- 27710775 TI - Evaluation of the impacts of cooperative adaptive cruise control on reducing rear end collision risks on freeways. AB - Although plenty of studies have been conducted recently about the impacts of cooperative adaptive cruise control (CACC) system on traffic efficiency, there are few researches analyzing the safety effects of this advanced driving assistant system. Thus, the primary objective of this study is to evaluate the impacts of the CACC system on reducing rear-end collision risks on freeways. The CACC model is firstly developed, which is based on the Intelligent Driver Model (IDM). Then, two surrogated safety measures, derived from the time-to-collision (TTC), denoting time exposed time-to-collision (TET) and time integrated time-to collision (TIT), are introduced for quantifying the collision risks. And the safety effects are analyzed both theoretically and experimentally, by the linear stability analysis and simulations. The theoretical and simulation results conformably indicate that the CACC system brings dramatic benefits for reducing rear-end collision risks (TET and TIT are reduced more than 90%, respectively), when the desired time headway and time delay are set properly. The sensitivity analysis indicates there are few differences among different values of the threshold of TTC and the length of a CACC platoon. The results also show that the safety improvements weaken with the decrease of the penetration rates of CACC on the market and the increase of time delay between platoons. We also evaluate the traffic efficiency of the CACC system with different desired time headway. PMID- 27710776 TI - Buffering the effects of peer victimization on adolescent non-suicidal self injury: The role of self-compassion and family cohesion. AB - Non-suicidal self-injury (NSSI) is a significant behavioral problem among adolescents all over the world. This study examined the longitudinal relationship between peer victimization and NSSI, as well as the buffering effects of self compassion and family cohesion on this relationship. Data were collected at two time points from 525 secondary school students (226 girls; Mage = 12.97, SD = 1.02) in China. Results showed that peer victimization (marginally) significantly predicted NSSI over time even after controlling for Wave 1 NSSI. This association was weakened under the condition of high levels of self-compassion. Findings of this study emphasize the buffering effect of self-compassion in the relationship between peer victimization and NSSI, and are informative for prevention and intervention of this behavioral problem. PMID- 27710777 TI - Early ultrastructural events of skeletal muscle damage following cardiotoxin induced injury and glycerol-induced injury. AB - In this study, we investigated the early changes of skeletal muscle damage in response to injuries induced by cardiotoxin (CTX) and glycerol by using both light microscopy and transmission electron microscopy. Normal, non-dystrophic, adult male mice were used in this study. Tibialis anterior (TA) muscles were injected either with CTX or glycerol. Samples were collected at intervals starting from 1h up to 4days after injury. Injured muscles were subjected to both histological and ultrastructural analyses. CTX-induced injury caused mitochondrial accumulation and swelling followed by lysis, while glycerol-induced injury caused accumulation of vesicles with focal disruption of the basal lamina, indicating that the injuries have different mechanisms of damage to myofibers. Moreover, inflammatory cells, including neutrophils and macrophages, were recruited earlier and in larger numbers after CTX-induced injury than after glycerol-induced injury. On the other hand, satellite cells (SCs) activation started at 6h after both injuries, as indicated by an increase in both the length and cytoplasmic-to-nuclear ratio. However, there were significantly longer SCs with a higher cytoplasmic-to-nuclear ratio in the CTX-injured muscles than in the glycerol-injured muscles at day 4. In conclusion, our results demonstrated a difference between CTX and glycerol in their damage to myofibers; CTX damages myofiber mitochondria, while glycerol damages the myofiber cell membrane and alters osmosis. In addition, CTX-induced injury caused earlier and more extensive inflammatory infiltration than did glycerol-induced injury. This study is the first study to shed light on the early events following skeletal muscle injury induced by CTX and glycerol. PMID- 27710779 TI - Probabilistic representation in syllogistic reasoning: A theory to integrate mental models and heuristics. AB - This paper presents a new theory of syllogistic reasoning. The proposed model assumes there are probabilistic representations of given signature situations. Instead of conducting an exhaustive search, the model constructs an individual based "logical" mental representation that expresses the most probable state of affairs, and derives a necessary conclusion that is not inconsistent with the model using heuristics based on informativeness. The model is a unification of previous influential models. Its descriptive validity has been evaluated against existing empirical data and two new experiments, and by qualitative analyses based on previous empirical findings, all of which supported the theory. The model's behavior is also consistent with findings in other areas, including working memory capacity. The results indicate that people assume the probabilities of all target events mentioned in a syllogism to be almost equal, which suggests links between syllogistic reasoning and other areas of cognition. PMID- 27710780 TI - Diminishing seasonality of self-harm: Temporal trends in Hong Kong SAR. AB - BACKGROUND: The study of temporal variation in self-harm is important to understanding the underlying mechanisms of its occurrence. There are fewer studies on temporal variation in self-harm than in suicide. The aim of this study was to examine the seasonality of self-harm in Hong Kong and to test the hypothesis of diminishing seasonality. METHODS: We used secondary data from medical records of self-harm obtained from all the public hospitals in Hong Kong under the management of the Hospital Authority. We identified 59,473 distinct episodes involving 36,411 patients. From these, monthly statistics of self-harm from January 2002 to December 2011 were calculated. Harmonic analysis was conducted to examine the presence and magnitude of seasonality. RESULTS: A bi seasonal pattern alongside a stronger one-cycle pattern from 2002 to 2006 was identified. During the period 1997-2001, this contracted to a one-cycle pattern with a peak in summer (May to July) and a nadir in winter (December). The magnitude of seasonality diminished greatly, as shown by harmonic analysis. The extent of diminishing seasonality was larger among women and people under 55 years old. LIMITATIONS: The study covered only self-harm patients who had visited a hospital. Cases which required no medical attention and those where the patient consulted private doctors could not be included, indicating bias towards more severe cases of injury and poisoning. CONCLUSION: This study provides some evidence of diminishing and even vanishing seasonality of self-harm in Hong Kong, a phenomenon mainly found in younger individuals. It could be related to the increasing use of social media to connect people, especially the younger generation. The impact of seasonal events and activities, as in the past, has become less significant in the social media era. PMID- 27710778 TI - Slow wave sleep and accelerated forgetting. AB - We investigated whether the benefit of slow wave sleep (SWS) for memory consolidation typically observed in healthy individuals is disrupted in people with accelerated long-term forgetting (ALF) due to epilepsy. SWS is thought to play an active role in declarative memory in healthy individuals and, furthermore, electrographic epileptiform activity is often more prevalent during SWS than during wakefulness or other sleep stages. We studied the relationship between SWS and the benefit of sleep for memory retention using a word-pair associates task. In both the ALF and the healthy control groups, sleep conferred a memory benefit. However, the relationship between the amount of SWS and sleep related memory benefits differed significantly between the groups. In healthy participants, the amount of SWS correlated positively with sleep-related memory benefits. In stark contrast, the more SWS, the smaller the sleep-related memory benefit in the ALF group. Therefore, contrary to its role in healthy people, SWS associated brain activity appears to be deleterious for memory in patients with ALF. PMID- 27710782 TI - Are You Smarter Than a Teenager? Maybe Not When It Comes to Reinforcement Learning. AB - Adolescence is a time of tumultuous behavior that may result, in part, from brain circuitry that enhances reward seeking. In this issue of Neuron, Davidow et al. (2016) present a convincing argument that adolescent brain functionality can be adaptive in certain contexts, particularly probabilistic learning environments. PMID- 27710781 TI - Percutaneous mitral valve repair with the MitraClip system in the elderly: One year outcomes from the GRASP registry. AB - BACKGROUND: Although mitral regurgitation (MR) affects a relevant and increasing number of elderly, an optimal management of this high-risk population is challenging. METHODS AND RESULTS: The aim of this prospective, observational study was to compare one-year outcomes of MitraClip therapy in high surgical risk patients with moderate-to-severe or severe MR between patients aged <75 versus >=75years. A total of 180 patients were included: 92 were <75years and 88 were >=75years old. At one-year follow-up the primary efficacy endpoint (composite of death, surgery for mitral valve dysfunction and grade 3+ or 4+ MR) occurred in 41 patients (24.5%), with similar rates between those aged <75years (23.9%) and those >=75years (25.2%), p=0.912. A total of 21 (12.2%) deaths were observed within 1year after the MitraClip procedure, without significant differences in cumulative mortality rates between elderly and younger patients (10.8% vs. 13.3%, respectively, p=0.574). Compared with baseline, the significant reduction in MR severity achieved after the procedure was sustained at one-year follow-up, in both elderly and younger patients and a significant improvement in NYHA functional class was observed in both groups. A total of 18 (10.0%) patients experienced a re-hospitalization for acute heart failure within one-year after the MitraClip procedure, with no significant differences between elderly and younger. At one-year follow-up both elderly and younger patients showed significant reductions in left ventricular volumes, with changes of similar extent between the two subgroups. CONCLUSIONS: MitraClip therapy can be considered a viable option also among subsets with more advanced age.

PMID- 27710783 TI - Context Processing and the Neurobiology of Post-Traumatic Stress Disorder. AB - Progress in clinical and affective neuroscience is redefining psychiatric illness as symptomatic expression of cellular/molecular dysfunctions in specific brain circuits. Post-traumatic stress disorder (PTSD) has been an exemplar of this progress, with improved understanding of neurobiological systems subserving fear learning, salience detection, and emotion regulation explaining much of its phenomenology and neurobiology. However, many features remain unexplained and a parsimonious model that more fully accounts for symptoms and the core neurobiology remains elusive. Contextual processing is a key modulatory function of hippocampal-prefrontal-thalamic circuitry, allowing organisms to disambiguate cues and derive situation-specific meaning from the world. We propose that dysregulation within this context-processing circuit is at the core of PTSD pathophysiology, accounting for much of its phenomenology and most of its biological findings. Understanding core mechanisms like this, and their underlying neural circuits, will sharpen diagnostic precision and understanding of risk factors, enhancing our ability to develop preventive and "personalized" interventions. PMID- 27710784 TI - Direct Measurement of Correlation Responses in Drosophila Elementary Motion Detectors Reveals Fast Timescale Tuning. AB - Animals estimate visual motion by integrating light intensity information over time and space. The integration requires nonlinear processing, which makes motion estimation circuitry sensitive to specific spatiotemporal correlations that signify visual motion. Classical models of motion estimation weight these correlations to produce direction-selective signals. However, the correlational algorithms they describe have not been directly measured in elementary motion detecting neurons (EMDs). Here, we employed stimuli to directly measure responses to pairwise correlations in Drosophila's EMD neurons, T4 and T5. Activity in these neurons was required for behavioral responses to pairwise correlations and was predictive of those responses. The pattern of neural responses in the EMDs was inconsistent with one classical model of motion detection, and the timescale and selectivity of correlation responses constrained the temporal filtering properties in potential models. These results reveal how neural responses to pairwise correlations drive visual behavior in this canonical motion-detecting circuit.

PMID- 27710787 TI - Clonally Related GABAergic Interneurons Do Not Randomly Disperse but Frequently Form Local Clusters in the Forebrain. AB - Progenitor cells in the medial ganglionic eminence (MGE) and preoptic area (PoA) give rise to GABAergic inhibitory interneurons that are distributed in the forebrain, largely in the cortex, hippocampus, and striatum. Two previous studies suggest that clonally related interneurons originating from individual MGE/PoA progenitors frequently form local clusters in the cortex. However, Mayer et al. and Harwell et al. recently argued that MGE/PoA-derived interneuron clones disperse widely and populate different forebrain structures. Here, we report further analysis of the spatial distribution of clonally related interneurons and demonstrate that interneuron clones do not non-specifically disperse in the forebrain. Around 70% of clones are restricted to one brain structure, predominantly the cortex. Moreover, the regional distribution of clonally related interneurons exhibits a clear clustering feature, which cannot occur by chance from a random diffusion. These results confirm that lineage relationship influences the spatial distribution of inhibitory interneurons in the forebrain. This Matters Arising paper is in response to Harwell et al. (2015) and Mayer et al. (2015), published in Neuron. See also the response by Turrero Garcia et al. (2016) and Mayer et al. (2016), published in this issue. PMID- 27710788 TI - Lineage Is a Poor Predictor of Interneuron Positioning within the Forebrain. AB - This Matters Arising Response paper addresses the Sultan et al. (2016) Matters Arising paper, published concurrently in Neuron. Clonally related excitatory neurons maintain a coherent relationship following their specification and migration. Whether cortical interneurons behave similarly is a fundamental question in developmental neuroscience. In Mayer et al. (2015), we reported that sibling interneurons disperse over several millimeters, across functional and anatomical boundaries. This finding demonstrated that clonality is not predictive of an interneuron's ultimate circuit specificity. Comparing the distribution of interneurons published in Mayer et al. to a random computer simulation, Sultan et al. suggest that clonally related interneurons are "not randomly dispersed." We argue that this comparison provides no insight into the influence of clonality on interneuron development because the entire population of cortical interneurons is "not randomly dispersed" in vivo. We find that the majority of cortical interneurons are similarly distributed whether or not they share a lineal relationship. Thus, at present there is no compelling evidence that clonality influences the position or function of interneurons. PMID- 27710790 TI - Lineage Relationships Do Not Drive MGE/PoA-Derived Interneuron Clustering in the Brain. AB - Neocortical excitatory and inhibitory neurons derive from distinct progenitor domains during embryonic development and migrate to their final positions, where they assemble into functional circuits. This process appears to be influenced by lineage relationships among locally born excitatory neurons, raising the intriguing possibility that this might be true for cortical interneurons. Two recent articles by the Fishell laboratory and our own used retrovirus-encoded DNA barcodes as unambiguous lineage-tracing tools to address this question, finding that clonally related inhibitory interneurons dispersed widely across the forebrain (Harwell et al., 2015; Mayer et al., 2015). This Matters Arising Response addresses the Sultan et al. (2016) Matters Arising paper, published concurrently in Neuron, where the authors reanalyze the datasets from both studies and propose a new interpretation, whereby clonally related interneurons would be considered clustered according to specific spatial constraints. After studying the report from Sultan et al. (2016) and carefully revisiting previously published studies, we find no evidence of lineage-dependent MGE/PoA-derived interneuron clustering in the forebrain. PMID- 27710793 TI - An Upside to Reward Sensitivity: The Hippocampus Supports Enhanced Reinforcement Learning in Adolescence. AB - Adolescents are notorious for engaging in reward-seeking behaviors, a tendency attributed to heightened activity in the brain's reward systems during adolescence. It has been suggested that reward sensitivity in adolescence might be adaptive, but evidence of an adaptive role has been scarce. Using a probabilistic reinforcement learning task combined with reinforcement learning models and fMRI, we found that adolescents showed better reinforcement learning and a stronger link between reinforcement learning and episodic memory for rewarding outcomes. This behavioral benefit was related to heightened prediction error-related BOLD activity in the hippocampus and to stronger functional connectivity between the hippocampus and the striatum at the time of reinforcement. These findings reveal an important role for the hippocampus in reinforcement learning in adolescence and suggest that reward sensitivity in adolescence is related to adaptive differences in how adolescents learn from experience. PMID- 27710792 TI - Principles of Synaptic Organization of GABAergic Interneurons in the Striatum. AB - The striatum, the entry nucleus of the basal ganglia, lacks laminar or columnar organization of its principal cells; nevertheless, functional data suggest that it is spatially organized. Here we examine whether the connectivity and synaptic organization of striatal GABAergic interneurons contributes to such spatial organization. Focusing on the two main classes of striatal GABAergic interneurons (fast-spiking interneurons [FSIs] and low-threshold-spiking interneurons [LTSIs]), we apply a combination of optogenetics and viral tracing approaches to dissect striatal microcircuits in mice. Our results reveal fundamental differences between the synaptic organizations of both interneuron types. FSIs target exclusively striatal projection neurons (SPNs) within close proximity and form strong synapses on the proximal somatodendritic region. In contrast, LTSIs target both SPNs and cholinergic interneurons, and synaptic connections onto SPNs are made exclusively over long distances and onto distal dendrites. These results suggest fundamentally different functions of FSIs and LTSIs in shaping striatal output. PMID- 27710791 TI - Subpallial Enhancer Transgenic Lines: a Data and Tool Resource to Study Transcriptional Regulation of GABAergic Cell Fate. AB - Elucidating the transcriptional circuitry controlling forebrain development requires an understanding of enhancer activity and regulation. We generated stable transgenic mouse lines that express CreERT2 and GFP from ten different enhancer elements with activity in distinct domains within the embryonic basal ganglia. We used these unique tools to generate a comprehensive regional fate map of the mouse subpallium, including sources for specific subtypes of amygdala neurons. We then focused on deciphering transcriptional mechanisms that control enhancer activity. Using machine-learning computations, in vivo chromosomal occupancy of 13 transcription factors that regulate subpallial patterning and differentiation and analysis of enhancer activity in Dlx1/2 and Lhx6 mutants, we elucidated novel molecular mechanisms that regulate region-specific enhancer activity in the developing brain. Thus, these subpallial enhancer transgenic lines are data and tool resources to study transcriptional regulation of GABAergic cell fate. PMID- 27710794 TI - Comparative approaches to escape. AB - Neural circuits mediating visually evoked escape behaviors are promising systems in which to dissect the neural basis of behavior. Behavioral responses to predator-like looming stimuli, and their underlying neural computations, are remarkably similar across species. Recently, genetic tools have been applied in this classical paradigm, revealing novel non-cortical pathways that connect loom processing to defensive behaviors in mammals and demonstrating that loom encoding models from locusts also fit vertebrate neural responses. In both invertebrates and vertebrates, relative spike-timing in descending pathways is a mechanism for escape behavior choice. Current findings suggest that experimentally tractable systems, such as Drosophila, may be applicable models for sensorimotor processing and persistent states in higher organisms. PMID- 27710795 TI - Common epigenetic variation in a European population of mentally healthy young adults. AB - DNA methylation represents an important link between structural genetic variation and complex phenotypes. The study of genome-wide CpG methylation and its relation to traits relevant to psychiatry has become increasingly important. Here, we analyzed quality metrics of 394,043 CpG sites in two samples of 568 and 319 mentally healthy young adults. For 25% of all CpGs we observed medium to large common epigenetic variation. These CpGs were overrepresented in open sea and shore regions, as well as in intergenic regions. They also showed a strong enrichment of significant hits in association analyses. Furthermore, a significant proportion of common DNA methylation is at least partially genetically driven and thus may be observed similarly across tissues. These findings could be of particular relevance for studies of complex neuropsychiatric traits, which often rely on proxy tissues. PMID- 27710797 TI - Arsenic removal by discontinuous ZVI two steps system for drinking water production at household scale. AB - Different countries in Europe still suffer of elevated arsenic (As) concentration in groundwaters used for human consumption. In the case of households not connected to the distribution system, decentralized water supply systems, such as Point of Use (POU) and Point of Entry (POE), offer a direct benefit for the consumers. Field scale ex-situ treatment systems based on metallic iron (ZVI) are already available for the production of reduced volumes of drinking water in remote areas (village scale). To address drinking water needs at larger scale, we designed a pilot unit able to produce an elevated daily volume of water for human consumption. We tested the long-term As removal efficiency of a two steps ZVI treatment unit for the production of 400 L/day clean water based on the combination of ZVI corrosion process with sedimentation and retention of freshly formed Fe precipitates. The system treated 100 MUg/L As(V)-contaminated oxic groundwater in a discontinuous operation mode at a flow rate of 1 L/min for 31 days. Final removal was 77-96% and the most performing step was aeration/sedimentation (A/S) tank with a 60-94% efficiency. Arsenic in the outflow slightly exceeded the drinking water limit of 10 MUg/L only after 6000 L treated and Fe concentration was always below 0.2 mg/L. Under proposed operating conditions ZVI passivation readily occurred and, as a consequence, Fe production sharply decreased. Arsenic mobility attached to particulate was 13-60% after ZVI column and 37-100% after A/S tank. Uniform amorphous cluster of Fe nanoparticles (100 nm) formed during aeration drove As removal process with an adsorption capacity corresponding to 20.5 mgAs/gFe. Research studies often focus only on chemico-physical aspects disregarding the importance of biological processes that may co-occur and interfere with ZVI corrosion, As removal and safe water production. We explored the microbial transport dynamics by flow cytometry, proved as a suitable tool to monitor the fate of both single cells and bioactive particles along the treatment train of the pilot unit. A net release of bioactive particles, representing on average 26.5% of flow cytometric events, was promoted by the ZVI filter, with densities 10 times higher than those found in the inflow. In conclusion, the proposed system was efficient to treat large daily volumes of As contaminated groundwater. However, filter design and operating conditions should be carefully adapted to specific situation, since several key factors affect As removal efficiency. An effort in the optimization of ZVI filter design should be made to reduce fast observed ZVI passivation and low As adsorption capacity of the whole filter. More attention to biomass retention and bioactive particles travelling within the unit should be given in order to elucidate bacteria influences on As removal efficiency and related sanitary risks on long term basis. PMID- 27710796 TI - Combined effect of TNF-alpha and cyclic stretching on gene and protein expression associated with mineral metabolism in cementoblasts. AB - OBJECTIVE: This work aims to investigate how the combination of TNF-alpha and cyclic stretching affects the expression of gene and protein associated with mineral metabolism in cementoblasts in vitro. DESIGN: Cementoblasts were cyclically stretched using the Flexcell tension system 4000 in the presence of 10 ng/ml TNF-alpha. Subsequently, the gene and protein expression CAP, Col I, BSP, OPG, RANKL and RUNX2 were detected using RT- PCR and ELISA/Western immunoblotting methods, respectively. RESULTS: Cyclic stretching alone enhanced CAP, Col I, OPG, RANKL and RUNX2 expression in an amplitude manner, while decreased BSP expression. Expression of all these proteins was attenuated in the presence of TNF-alpha whether the cells were exposed to cyclic stretching or not. The ratio of RANKL/OPG was increased at any stimulation. CONCLUSION: This results suggest that TNF-alpha affected the regulation of gene and protein expression induced by mechanical stimulation in cementoblasts. This may suppress anabolism and promote catabolism of cementum. It suggests that inflammatory cytokine may impair the cementum remodeling under mechanical stimulation. PMID- 27710798 TI - Removal of triazine-based pollutants from water by carbon nanotubes: Impact of dissolved organic matter (DOM) and solution chemistry. AB - Adsorption of organic pollutants by carbon nanotubes (CNTs) in the environment or removal of pollutants during water purification require deep understanding of the impacts of the presence of dissolved organic matter (DOM). DOM is an integral part of environmental systems and plays a key role affecting the behavior of organic pollutants. In this study, the effects of solution chemistry (pH and ionic strength) and the presence of DOM on the removal of atrazine and lamotrigine by single-walled CNTs (SWCNTs) was investigated. The solubility of atrazine slightly decreased (~5%) in the presence of DOM, whereas that of lamotrigine was significantly enhanced (by up to ~70%). Simultaneous introduction of DOM and pollutant resulted in suppression of removal of both atrazine and lamotrigine, which was attributed to DOM-pollutant competition or blockage of adsorption sites by DOM. However the decrease in removal of lamotrigine was also a result of its complexation with DOM. Pre-introduction of DOM significantly reduced pollutant adsorption by the SWCNTs, whereas introduction of DOM after the pollutant resulted in the release of adsorbed atrazine and lamotrigine from the SWCNTs. These data imply that DOM exhibits higher affinity for the adsorption sites than the triazine-based pollutants. In the absence of DOM atrazine was a more effective competitor than lamotrigine for adsorption sites in SWCNTs. However, competition between pollutants in the presence of DOM revealed lamotrigine as the better competitor. Our findings help unravel the complex DOM organic pollutant-CNT system and will aid in CNT-implementation in water purification technologies. PMID- 27710799 TI - Trace levels of sewage effluent are sufficient to increase class 1 integron prevalence in freshwater biofilms without changing the core community. AB - Most river systems are impacted by sewage effluent. It remains unclear if there is a lower threshold to the concentration of sewage effluent that can significantly change the structure of the microbial community and its mobile genetic elements in a natural river biofilm. We used novel in situ mesocosms to conduct replicated experiments to study how the addition of low-level concentrations of sewage effluent (nominally 2.5 ppm) affects river biofilms in two contrasting Chalk river systems, the Rivers Kennet and Lambourn (high/low sewage impact, respectively). 16S sequencing and qPCR showed that community composition was not significantly changed by the sewage effluent addition, but class 1 integron prevalence (Lambourn control 0.07% (SE +/- 0.01), Lambourn sewage effluent 0.11% (SE +/- 0.006), Kennet control 0.56% (SE +/- 0.01), Kennet sewage effluent 1.28% (SE +/- 0.16)) was significantly greater in the communities exposed to sewage effluent than in the control flumes (ANOVA, F = 5.11, p = 0.045) in both rivers. Furthermore, the difference in integron prevalence between the Kennet control (no sewage effluent addition) and Kennet sewage-treated samples was proportionally greater than the difference in prevalence between the Lambourn control and sewage-treated samples (ANOVA (interaction between treatment and river), F = 6.42, p = 0.028). Mechanisms that lead to such differences could include macronutrient/biofilm or phage/bacteria interactions. Our findings highlight the role that low-level exposure to complex polluting mixtures such as sewage effluent can play in the spread of antibiotic resistance genes. The results also highlight that certain conditions, such as macronutrient load, might accelerate spread of antibiotic resistance genes. PMID- 27710800 TI - Noninvasive assessment of myocardial bridging by coronary flow velocity reserve with transthoracic Doppler echocardiography: vasodilator vs. inotropic stimulation. AB - BACKGROUND: To consider hemodynamic assessment of myocardial bridging (MB) adequate, it is believed that inotropic stimulation with dobutamine should be estimated because its dynamic nature depends on the degree of extravascular coronary compression. This study evaluated comparative assessment of hemodynamic relevance of MB using coronary flow velocity reserve (CFVR) measurements by transthoracic Doppler echocardiography (TTDE) with vasodilatative and inotropic challenges. METHODS: This prospective study included forty-four patients with angiographic evidence of isolated MB of the left anterior descending coronary artery (LAD) and systolic compression of >=50% diameter stenosis. All patients were evaluated by exercise stress-echocardiography (ExSE) test for signs of myocardial ischemia, and CFVR of the distal segment of LAD during iv.infusion of adenosine (ADO:140MUg/kg/min) and iv.infusion of dobutamine (DOB:10 40MUg/kg/min), separately. RESULTS: Exercise-SE was positive for myocardial ischemia in 8/44 (18%) of patients. CFVR during ADO was significantly higher than CFVR during peak DOB (2.85+/-0.68 vs. 2.44+/-0.48, p=0.002). CFVR during peak DOB was significantly lower in SE-positive group in comparison to SE-negative group (2.01+/-0.16 vs. 2.54+/-0.47, p<0.001), but not for ADO (2.47+/-0.51 vs. 2.89+/ 0.70, p=0.168), respectively. Multivariable logistic analysis showed that CFVR peak DOB was the most significant predictor of functional significant MB (OR 0.011, 95%CI: 0.001-0.507, p=0.021). Receiver-operating characteristic curves have shown that TTDE-CFVR obtained by high-dose of dobutamine infusion is better than those by adenosine regarding to functional status of MB (AUC 0.861, p=0.004; AUC 0.674, p=0.179, respectively). CONCLUSIONS: Non-invasive CFVR measurement by TTDE during inotropic stimulation, in comparison to vasodilation, provides more reliable functional evaluation of MB.

PMID- 27710803 TI - Clinical outcome of statin plus ezetimibe versus high-intensity statin therapy in patients with acute myocardial infarction propensity-score matching analysis. AB - BACKGROUND: It is unclear whether simvastatin-ezetimibe could be an alternative therapy to high-intensity statin therapy in high-risk patients. The aim of this study was to compare the clinical outcomes of simvastatin-ezetimibe and high intensity statin therapy in patients with acute myocardial infarction (AMI), and especially in those with high-risk factor. METHODS: A total of 3520 AMI patients in the KAMIR (Korea Acute Myocardial Infarction Registry) were classified into simvastatin-ezetimibe group (n=1249) and high-intensity statin group (n=2271). Multivariate analysis and propensity-score matching analysis were performed. The primary endpoint was major adverse cardiac events (MACE) at 12-months follow-up. RESULTS: In overall AMI patients, MACE occurred in 116 patients (9.3%) in simvastatin-ezetimibe group and 116 patients (5.1%) in high-intensity statin group. The difference in MACE between groups was driven by repeat revascularization (5.9% vs. 2.2%). After propensity matching analysis, simvastatin-ezetimibe was associated with a higher incidence of MACE than high intensity statin therapy (adjusted hazard ratio: 3.090, 95% confidence interval: 1.715 to 5.566, p<0.001). However, in patients with high-risk factors, such as diabetes, old age, or heart failure, simvastatin-ezetimibe had similar incidence of MACE compared with high-intensity statin therapy in further adjusted analysis. CONCLUSIONS: In overall AMI patients, high-intensity statin therapy had better clinical outcomes than simvastatin-ezetimibe. However, in patients with high-risk factor, simvastatin-ezetimibe had comparable clinical outcomes to high-intensity statin therapy. Therefore, simvastatin-ezetimibe could be used as an alternative to high-intensity statin therapy in such patients. PMID- 27710805 TI - Protein levels in Keap1-Nrf2 system in human failing heart. PMID- 27710806 TI - Sleep-related changes in cardiovascular autonomic regulation in left coronary artery ligation rats: Neural mechanism facilitating arrhythmia after myocardial infarction. AB - BACKGROUND: Autonomic imbalance with increased sympathetic and decreased parasympathetic activities is observed in patients after myocardial infarction (MI). We aimed to investigate sleep-related changed in autonomic regulation in left coronary artery (LCA) ligation rats. METHODS: Wireless transmission of polysomnographic recording was performed in sham and LCA ligation male rats during normal daytime sleep with and without atenolol treatment. Spectral analyses of the electroencephalogram (EEG) and electromyogram (EMG) were evaluated to define active waking (AW), quiet and paradoxical sleeps (QS, PS). Cardiac autonomic activities were measured by analyzing the power spectrum of heart rate variability (HRV). EEG, EMG and HRV were recorded over 6h for consecutive 3days in all groups. RESULTS: In LCA ligation group, there were higher LF and LF/HF ratio on QS phase, but not AW and PS phases, compared to atenolol treated sham and LCA ligation groups, respectively. The HF component was not significantly changed on all groups in both sleep and awake phases. Sleep interruption was more frequent in LCA ligation rats compared to sham, and it was not found in LCA ligation with atenolol treatment group. Increased AW, PS and decreased QS time were noted in LCA ligation group, compared to sham and it was restored to baseline in LCA ligation with atenolol treatment group. CONCLUSIONS: Our results demonstrate significant sleep fragmentations with sympathetic hyperactivity during QS stages after MI, and atenolol could restore the autonomic dysfunction and sleep disturbance. The finding explains the cause of sleep related fetal arrhythmia and sudden cardiac death after MI. PMID- 27710807 TI - Cognitive and functional changes associated with Abeta pathology and the progression to mild cognitive impairment. AB - Cognitively-normal people with evidence of beta-amyloid (Abeta) pathology and subtle cognitive dysfunction are believed to be at high risk for progression to mild cognitive impairment due to Alzheimer's disease (AD). Clinical trials in later stages of AD typically include a coprimary endpoint to demonstrate efficacy on both cognitive and functional assessments. Recent trials focus on cognitively normal people, but functional decline has not been explored for trial designs in this group. The goal of this study was therefore to characterize cognitive and functional decline in (1) cognitively-normal people converting to mild cognitive impairment (MCI) and (2) cognitively-normal beta-amyloid-positive (Abeta+) people. Specifically, we sought to identify and compare the cognitive and functional assessments and their weighted combinations that maximize the longitudinal decline specific to these 2 groups. We studied 68 people who converted from normal cognition to MCI and 70 nonconverters, as well as 137 Abeta+ and 210 beta-amyloid-negative cognitively-normal people. We used bootstrap aggregation and cross-validated mixed-models to estimate the distribution of weights applied to cognitive and functional outcomes to form composites. We also evaluated best subset optimization. Using optimized composites, we estimated statistical power for a variety of clinical trial scenarios. Overall, 55.4% of cognitively-normal to MCI converters were Abeta+. Large gains in power estimates were obtained when requiring participants to have both subtle cognitive dysfunction and Abeta pathology compared with requiring Abeta pathology alone. Additional power resulted when including functional as well as cognitive outcomes as part of the composite. Composites formed by applying equal weights to all measures provided the highest estimates of cross-validated power, although similar to both continuous weight optimization and best subset optimization. Using a composite to detect a 30% slowing of decline, 80% power was obtained for predicted Abeta+ converters with 375 completers/arm for a 30-month trial using a combination of cognitive/ functional measures. In the Abeta+ group, power to approach levels suitable for a phase III clinical trial would require considerably larger sample sizes. Composites incorporating both cognitive and functional measures may substantially increase the power of a trial in a preclinical (Abeta+) AD population with subtle evidence of cognitive dysfunction. PMID- 27710808 TI - Coronary atheroma progression rates in men and women following high-intensity statin therapy: A pooled analysis of REVERSAL, ASTEROID and SATURN. AB - BACKGROUND AND AIMS: High-intensity statin therapy (HIST) reduces cardiovascular events, however, sex-related differences in treatment effects are not well characterized. METHODS: A patient-level post hoc pooled analysis of 3 randomized trials utilizing serial coronary intravascular ultrasound was undertaken, testing the anti-atherosclerotic effects of HIST in coronary disease patients. Sex related differences in changes (Delta) in coronary percent atheroma volume (PAV) were ascertained following 18-24 months of HIST (atorvastatin 80 mg or rosuvastatin 40 mg daily), and further characterized according to on-treatment lipid and lipoprotein levels. RESULTS: In women (n = 451) compared with men (n = 1190), on-treatment levels of LDL-C (68 +/- 24 vs. 67 +/- 22 mg/dl, p=0.62) and apoB (77 +/- 23 vs. 76 +/- 20 mg/dL, p=0.51) were similar; levels of HDL-C (53 +/ 12 vs. 47 +/- 11 mg/dl, p < 0.001), apoA1 (154 +/- 26 vs. 140 +/- 24 mg/dl, p < 0.001), triglycerides [122 (95, 158) vs. 114 (89, 154) mg/dl, p=0.012] and CRP [1.7 (0.9, 3.8) vs. 1.1 (0.6, 2.7) mg/l, p < 0.001] were higher; while the total cholesterol/HDL-C (TC/HDL-C) ratio was lower (2.9 +/- 0.8 vs. 3.1 +/- 0.8, p < 0.001). Compared with men, women harbored significantly lower baseline PAV (34.8 +/- 8.7 vs. 38.3 +/- 8.8%, p < 0.001), yet demonstrated significantly greater PAV regression (DeltaPAV -1.07 +/- 0.26 vs. -0.66 +/- 0.23%, p=0.02). When achieved on-treatment levels of LDL-C were <64 mg/dl, apoB <73 mg/dl, non-HDL-C <88.8 mg/dl, and TC/HDL-C <2.99, women demonstrated significantly greater PAV regression than men. Multivariable analysis revealed female sex to independently associate with PAV regression (coefficient -0.66, p=0.02). CONCLUSIONS: Women demonstrate greater degrees of coronary plaque regression compared with men following long-term HIST, especially in the setting of lower achieved atherogenic lipoprotein levels.

AB - In this article the authors aim is to investigate and analyze the various key parameters of an organic D-pi-A type novel nonlinear optical material 2, 4, 5 trimethoxy-4'-chlorochalcone (2,4,5TMCC) through experimental and quantum chemical studies. The Claisen-Schmidt condensation reaction mechanism was applied to synthesize the 2,4,5TMCC compound and its single crystal was grown by a slow evaporation solution growth (low cost) technique. The crystal structure was confirmed by powder X-ray diffraction analysis. The robust vibrational study has been done using FT-IR and FT-Raman spectra and its NLO activity was discussed. The factor group analysis was also performed. The optical absorption spectrum was recorded and the band gap was calculated to be 2.8eV. In photoluminescence spectrum, an intense emission band at ~540nm has been observed which shows that the grown crystals can be used in green organic light emitting diodes and laser applications. To achieve the stable ground state molecular geometry of 2,4,5TMCC, the computational techniques were applied at different levels of theory using 6 31G* basis set. The calculated geometrical parameters and vibrational spectra are found to be in good agreement with the experimental results. To probe the optical properties of the title compound the time dependent density functional theory was applied. The excitation wavelength was observed at ~398.63nm calculated at B3LYP/6-31G* level of theory and found close to experimental value (i.e. 396nm). The static first hyperpolarizability value is found to be 136 times higher than prototype urea molecule. Additionally, the molecular level approach was attained as HOMO-LUMO gap and electrostatic potential maps. The DSC study reveals that the titled material is stable up to 149 degrees C. The photophysical and nonlinear optical properties suggest that the titled material could be a better choice for the fabrication of optoelectronic devices.

AB - A new 4-hydroxy-1,8-naphthalimide-based compound (probe 1) has been designed and synthesized. The colorimetric and fluorescent properties of probe 1 towards hydrogen sulfide (H2S) were investigated in detail. The results show that the probe 1 could selectively and sensitively recognize H2S rather than other reactive sulfur species. The reaction mechanism of this probe is an intramolecular cyclization caused by the Michael addition of H2S to give 4 hydroxy-1,8-naphthalimide. The intramolecular charge transfer of 4-hydroxy-1,8 naphthalimide is significant. Probe 1 quickly responded to H2S and showed a 75 fold fluorescence enhancement in 5min. Moreover, probe 1 could detect H2S quantitatively with a detection limit as low as 0.23MUM.

AB - With the shift towards interprofessional education to promote collaborative practice, clinical preceptors are increasingly working with trainees from various professions to provide patient care. It is unclear whether and how preceptors modify their existing precepting approach when working with trainees from other professions. There is little information on strategies for this type of precepting, and how preceptors may foster or impede interprofessional collaboration. The purpose of this qualitative description pilot study was to identify current methods preceptors use to teach trainees from other professions in the clinical setting, particularly advanced practice nursing and medical trainees, and to identify factors that support or impede this type of precepting. Data collected through observations and interviews were analyzed by the research team using thematic analysis procedures. Three major themes were identified: 1) a variety of teaching approaches and levels of engagement with trainees of different professions, 2) preceptor knowledge gaps related to curricula, goals, and scope of practice of trainees from other professions, and 3) administrative, structural and logistical elements that impact the success of precepting trainees from different professions in the clinical setting. This study has implications for faculty development and evaluation of current precepting practices in clinical settings. PMID- 27710812 TI - Neck range of motion following cervical spinal fusion: A comparison of patient centered and objective assessments. AB - OBJECTIVES: A common question posed by patients undergoing cervical fusion pertains to the likelihood of perceiving a postoperative limitation in neck mobility. The aim of this study was to assess the change in neck mobility after subaxial cervical fusion using an objective range of motion (ROM) measure and patient reported assessment. PATIENTS AND METHODS: Patients older than 18 years of age, undergoing first-time anterior or posterior subaxial cervical arthrodesis for a symptomatic spondylotic process (radiculopathy, cervical spondylotic myelopathy or primary neck pain) at a single center were eligible. Assessment included: 1) neck pain on a numeric rating scale; 2) four-directional objective neck mobility using the validated cervical ROM goniometer; and 3) a novel Mobility Assessment Scale (MAS) for patient perceived neck mobility. Subjects were dichotomized by number of levels fused (1-2 levels and >=3 levels). RESULTS: There were 25 patients with a mean of 2.7+/-1.5 levels fused. Neck pain was improved in both groups with mean change of -3.4 [95% CI -4.7,-2.1], p=0.004 for 1-2 levels and -3.5 [95% CI -5.4,-1.5], p=0.009 for >=3 levels. MAS score improved significantly in group undergoing 1-2 level fusion (-1.8 [95% CI: -3.1, 0.4], p=0.016) but not in those with >=3 levels fused. There was a significant positive correlation between MAS and neck pain in the 1-2 level fusion group (rs=0.667, p=0.012) but not in the >=3 level group. Objective neck mobility did not changed significantly in either group. CONCLUSIONS: Patient reported neck mobility was significantly improved following 1-2 level cervical fusion. This change correlated significantly with patient reported improvement in neck pain. No significant difference in reported neck mobility was found in those undergoing fusion of >=3 levels.

AB - Gastrin controls gastric acid secretion and mucosal cell growth, especially of enterochromaffin-like cells, via gastrin/cholecystokinin-2 receptor (CCK2R) binding and downstream signalling. Studies in animal models, healthy subjects and patients with gastric neuroendocrine tumours provide compelling evidence to justify developing a CCK2R antagonist (CCK2RA) for preventing or treating the trophic effects of hypergastrinaemia or conditions expressing CCK2R, and with or without a proton pump inhibitor, for treating gastric acid-related conditions. Many compounds have been studied, but most have had problems with potency, selectivity for CCK2 versus CCK1 receptor, solubility or oral bioavailability. None has yet been marketed. Netazepide and Z-360 are currently undergoing clinical development, for treatment of gastric neuroendocrine tumours and pancreatic cancer, respectively. There are several other potential indications for a CCK2RA and an unmet need. PMID- 27710814 TI - Structure and genetics of the O-antigens of Escherichia coli O182-O187. AB - O-polysaccharides (OPSs) were obtained by mild acid degradation of the lipopolysaccharides of Escherichia coli O182-O187, and their structures were established by sugar analysis, Smith degradation, and 1H and 13C NMR spectroscopy. In addition to the monosaccharides that occur often in E. coli OPSs (d-Glc, d-Gal, d-Man, d-GlcNAc, d-GalNAc, d-GlcA, l-Fuc, d-Rib), a number of less common components were identified as the OPS constituents, including 2-acetamido 2-deoxy-l-quinovose and 4-deoxy-4-[(S)-3-hydroxybutanoyl-l-alanyl]-d-quinovose (O186), 3-acetamido-3-deoxy-d-fucose (O187), 3-deoxy-3-[(R)-3-hydroxybutanoyl]-d fucose (O184), and 2,3-diacetamido-2,3-dideoxy-l-rhamnose (O182). The OPS structures of E. coli O183 and O182 are identical to those of the OPS of Shigella boydii type 10 and the capsular polysaccharide of E. coli K48, respectively. The OPSs of E. coli O186 and O123 are closely related differing in the presence of a Glc residue in the former in place of a GlcNAc residue in the latter. The O antigen gene clusters of the bacteria studied were analyzed and their contents were found to be consistent with the OPS structures. Predicted glycosyltransferases encoded in the gene clusters were tentatively assigned to glycosidic linkages based on similarities to sequences of other E. coli O serogroups available from GenBank and taking into account the OPS structures established. PMID- 27710815 TI - Multivalent S-sialoside protein conjugates block influenza hemagglutinin and neuraminidase. AB - A new class of S-sialoside Human Serum Albumin (HSA) and Bovine Serum Albumin (BSA) conjugates were prepared to enhance the binding affinity to hemagglutinin (HA) and neuraminidase (NA). The valency of glycoconjugates was controlled by the reaction ratio of the S-sialoside monomer and protein. Hemagglutination inhibition assay showed that these synthetic glycoproteins have higher affinity to HA than the small clusters of sialosides with lower valency, due to multivalent effect and optimized three dimensional presentation of sialosides on the protein platform. The results of fluorescent NA inhibition assay showed that some of the conjugates have moderate NA inhibitory activity, in comparison to the monomer and low valent conjugates with weak or none inhibitory activity. These synthetic sialylated proteins were not cytotoxic with concentrations up to 100 MUM, since the sialylation did not change the secondary structure of protein. This new kind of conjugates can be used as lead compounds for antiviral drug design and the construction of pseudo sialoside-protein conjugates library to investigate the carbohydrate-HA/NA recognition process and a platform for the influenza virus capturing. PMID- 27710816 TI - Analysis of stochastic crystallization in micron-sized droplets of undercooled liquid l-arabitol. AB - Kinetics of isothermal crystallization of l-arabitol were analyzed from the undercooled liquid state within micron-sized droplets from micro-Raman spectroscopy. This study reveals that crystallization slightly above Tg is controlled by stochastic heterogeneous nucleation inherent to the droplet size. Microscopic Raman investigations performed in droplets give the unique opportunity to analyze the pure metastable Form II of l-arabitol. It was found that Form II is characterized by a molecular packing more compact than that of the stable Form I, inherent to strong intermolecular hydrogen bonding. Kinetics laws obtained by analyzing several droplets at different temperatures, reveal the transient character of Form II, quasi systematically detected during the crystallization process of form I. Form II appears as the first step of crystallization prior to successive short-living metastable states which is necessary to achieve a complete crystallization in Form I. It was found that the kinetics of conversion between the metastable states (Form II) into Form I is dependent on the amount of strong hydrogen bonding distinctive of Form II.

AB - BACKGROUND: the health and survival of newborns depend on high levels of attention and care from caregivers. The growth and development of some infants are unhealthy because of their mother's or caregiver's lack of knowledge or the use of inappropriate or traditional child-rearing practices that may be harmful. OBJECTIVE: to develop a newborn care educational programme and evaluate its impact on infant and maternal health in Nepal. DESIGN: a randomised controlled trial. PARTICIPANTS: one hundred and forty-three mothers were randomly assigned to the intervention (n=69) and control (n=74) groups. Eligible participants were primiparous mothers who had given birth to a single, full-term, healthy infant, and were without a history of obstetric, medical, or psychological problems. METHODS: prior to being discharged from the postnatal unit, the intervention group received our structured newborn care education programme, which consisted of one-on-one educational sessions lasting 10-15minutes each and one postpartum follow-up telephone support within two weeks after discharge, in addition to the hospital's routine general newborn care education. The control group received only the regular general newborn care education. Outcomes were measured by using Newborn care Knowledge Questionnaires, Karitane Parenting Confidence Scale, State Trait Anxiety Inventory for Adults and infant health and care status. FINDINGS: the number of mothers attending the health centre due to the sickness of their babies was significantly decreased in the intervention group compared to the control group. Moreover, the intervention group had significant increases in newborn care knowledge and confidence, and decreases in anxiety, compared with the control group. CONCLUSIONS: the structured newborn care education programme enhanced the infant and mother health. Moreover, it increased maternal knowledge of newborn care and maternal confidence; and reduced anxiety in primiparous mothers. Thus, this educational programme could be integrated into routine educational programs to promote maternal and infant well-being in Nepalese society. PMID- 27710818 TI - Attentional orienting and executive control are affected by different types of meditation practice. AB - Several studies have demonstrated the beneficial effects of meditation on attention. The present study investigated the relationship between focused attention (FA) and open monitoring (OM) meditation skills and the various functions of attention. In Experiment 1, we executed the attention network test and compared the performance of experts on dandao meditation with that of ordinary people on this test. The results indicated that the experts specializing in OM meditation demonstrated greater attentional orienting ability compared with those specializing in FA meditation and the control group. In addition, both expert groups registered improvements in their executive control abilities compared with the control group. In Experiment 2, we trained beginners in FA meditation for 3months. The results showed that the experimental group exhibited significantly enhanced executive control ability. We infer that FA meditation skills promote executive control function and OM meditation skills promote both executive control and attentional orienting functions. PMID- 27710819 TI - Severe fatigue in type 1 diabetes: Exploring its course, predictors and relationship with HbA1c in a prospective study. AB - AIMS: To prospectively identify the course of severe fatigue, its predictors and the relationship with HbA1c in patients with type 1 diabetes. METHODS: 214 adult patients completed questionnaires on fatigue severity and fatigue-related factors at baseline. HbA1c was retrieved from medical records. After 43months, fatigue severity and HbA1c were reassessed in 194 patients. A logistic regression analysis was used to determine predictors of severe fatigue at follow-up with various cognitive-behavioral and clinical factors as potential predictors. The relationship between fatigue and HbA1c was investigated in a sub-analysis by differentiating between patients with suboptimal glucose control [HbA1c>7% (53mmol/mol)] and optimal glucose control [HbA1c?7% (53mmol/mol)]. RESULTS: The prevalence of severe fatigue was 40% at baseline and 42% at follow-up. In three out of four severely fatigued patients at baseline (76%), severe fatigue persisted over time. More depressive symptoms, more pain, sleep disturbances, lower self-efficacy concerning fatigue, less confidence in diabetes self-care, more fatigue severity at baseline and more diabetes complications predicted severe fatigue at follow-up. Over time, HbA1c at baseline was positively associated with fatigue severity at follow-up in both groups (suboptimal glucose control: r=.18, p<.05; optimal glucose control: r=.09, p<.05). CONCLUSIONS: About three quarters of fatigued[corrected] patients with type 1 diabetes suffer from persistent fatigue. Aside from the number of diabetes complications, no clinical factors explained the persistence of fatigue. HbA1c and fatigue were weakly associated in a sub-analysis. Since the strongest predictors of severe fatigue were cognitive-behavioral factors, behavioral interventions might be effective in decreasing fatigue. PMID- 27710822 TI - Effect of spacer length on the interfacial behavior of N,N'-bis(dimethylalkyl) alpha,omega-alkanediammonium dibromide gemini surfactants in the absence and presence of ZnO nanoparticles. AB - In this paper the interfacial behavior of aqueous solutions of cationic gemini surfactants of the, N,N'-bis(dimethylalkyl)-alpha,omega-alkanediammoniumdibromide type (known as the 12-s-12 series), in the absence and presence of ZnO nanoparticles was studied. Equilibrium and dynamic interfacial tension between n decane and aqueous surfactant solutions were investigated. It was concluded that the synergistic effect between surfactants and nanoparticles increases the surfactant efficiency with respect to reducing the interfacial tension. Moreover, the magnitude of the effect of ZnO nanoparticles on the interfacial tension decreases with increasing length of the spacer group in the gemini surfactant structure. Dynamic studies illustrate that the migration mechanism of gemini surfactants (regardless of the presence of ZnO) from the bulk to the interface was controlled by both diffusion and adsorption. The effect of spacer length on the contact angle and emulsion stability both with and without nanoparticles was also studied. PMID- 27710820 TI - Geographical variation in the progression of type 2 diabetes in Peru: The CRONICAS Cohort Study. AB - BACKGROUND: The study aims were to estimate the incidence and risk factors for T2D in four settings with different degree of urbanization and altitude in Peru. METHODS: Prospective cohort study conducted in urban, semi-urban, and rural areas in Peru. An age- and sex-stratified random sample of participants was taken from the most updated census. T2D was defined as fasting blood glucose ?7.0mmol/L or taking anti-diabetes medication. Exposures were divided into two groups: geographical variables (urbanization and altitude), and modifiable risk factors. Incidence, relative risks (RR), 95% confidence intervals (95%CI), and population attributable fractions (PAF) were estimated. RESULTS: Data from 3135 participants, 48.8% males, mean age 55.6years, was analyzed. Overall baseline prevalence of T2D was 7.1% (95%CI 6.2-8.0%). At follow-up, including 6207 person years of follow-up, a total of 121 new T2D cases were accrued, equating to an incidence of 1.95 (95%CI 1.63-2.33) per 100 person-years. There was no urban to rural gradient in the T2D incidence; however, compared to sea level sites, participants living in high altitude had a higher incidence of diabetes (RR=1.58; 95%CI 1.01-2.48). Obesity had the highest attributable risk for developing T2D, although results varied by setting, ranging from 14% to 80% depending on urbanization and altitude. CONCLUSIONS: Our results suggest that the incidence of T2D was greater in high altitude sites. New cases of diabetes were largely attributed to obesity, but with substantial variation in the contribution of obesity depending on the environment. These findings can inform appropriate context-specific strategies to reduce the incidence of diabetes. PMID- 27710821 TI - Effects of linagliptin monotherapy compared with voglibose on postprandial blood glucose responses in Japanese patients with type 2 diabetes: Linagliptin Study of Effects on Postprandial blood glucose (L-STEP). AB - AIMS: To compare the efficacy on glycemic parameters between a 12-week administration of once-daily linagliptin and thrice-daily voglibose in Japanese patients with type 2 diabetes. METHODS: In a multi-center, randomized, parallel group study, 382 patients with diabetes were randomized to the linagliptin group (n=192) or the voglibose group (n=190). A meal tolerance test was performed at weeks 0 and 12. Primary outcomes were the change from baseline to week 12 in serum glucose levels at 2h during the meal tolerance test, HbA1c levels, and serum fasting glucose levels, which were compared between the 2 groups. RESULTS: Whereas changes in serum glucose levels at 2h during the meal tolerance test did not differ between the groups, the mean change in HbA1c levels from baseline to week 12 in the linagliptin group (-0.5+/-0.5% [-5.1+/-5.4mmol/mol]) was significantly larger than in the voglibose group (-0.2+/-0.5% [-2.7+/ 5.4mmol/mol]). In addition, there was significant difference in changes in serum fasting glucose levels (-0.51+/-0.95mmol/L in the linagliptin group vs. -0.18+/ 0.92mmol/L in the voglibose group, P<0.001). The incidences of hypoglycemia, serious adverse events (AEs), and discontinuations due to AEs were low and similar in both groups. However, gastrointestinal AEs were significantly lower in the linagliptin group (1.05% vs. 5.85%; P=0.01). CONCLUSIONS: These data suggested that linagliptin monotherapy had a stronger glucose-lowering effect than voglibose monotherapy with respect to HbA1c and serum fasting glucose levels, but not serum glucose levels 2h after the start of the meal tolerance test. PMID- 27710823 TI - Facile template-free fabrication of iron manganese bimetal oxides nanospheres with excellent capability for heavy metals removal. AB - Iron manganese bimetal oxides (IMBO) nanospheres were synthesized via a facile and environmentally friendly template-free approach. The obtained IMBO with large surface area and abundant surface functional groups exhibited excellent performance for heavy metals removal from aqueous solution, with the maximum adsorption capacities of As(V) and Cr(VI) were 132.77mg/g and 105.96mg/g, respectively. The adsorption mechanism study confirmed that except for electrostatic attraction, both surface hydroxyl group (OH-) and carbonate group (CO32-) simultaneously played a key role in the ion-exchange process with As(V) and Cr(VI) species, which finally formed inner-sphere surface complexes on the interface of IMBO. Furthermore, the remarkable removal of As(V) and Cr(VI) by fixed-bed column was also observed in the presence of various commonly competing anions, and the effective working capacities of IMBO for As(V) and Cr(VI) were approximately 410 pore volume (PV) and 320 pore volume (PV) when the breakthrough point was set at 10ppb. The exhausted IMBO could be easily regenerated by using a NaOH solution (0.1M). These results demonstrated that this IMBO was a potential and attractive adsorbent for the decontamination of arsenic/chromium polluted water system. PMID- 27710824 TI - Tobacco prevention and reduction with nursing students: A non-randomized controlled feasibility study. AB - BACKGROUND: Prevalence of tobacco use among nurses and nursing students is disproportionally high in Germany. However, from a public health perspective they are considered to be an important group for delivering smoking cessation interventions. As delivery of tobacco-related treatment depends on own smoking status, smoking prevention and cessation among the nursing professions is indicative for improving nurse and public health. OBJECTIVE: To evaluate the feasibility and effects of a comprehensive tobacco prevention and reduction program on psychosocial and environmental factors related to smoking behavior of nursing students. METHODS: Between 2014 and 2015, a non-randomized, controlled feasibility study was conducted in 12 schools of nursing with 397 nursing students in Germany. Students in the intervention group received a program (ASTRA) consisting of an introductory session, steering committee workshop, stress prevention lessons, evidence-based smoking cessation intervention, and action project. Six months after baseline assessment, change in smoking-related protective and risk factors was determined. Secondary endpoints included smoking behavior. RESULTS: The program was implemented in total in 5 of 7 intervention schools. About one third of smoking nursing students participated in a cessation intervention. The program seems to do better than a minimal intervention booklet in four primary outcomes: perceived descriptive, subjective, and injunctive norms towards smoking and nursing as well as perceived social support. As anticipated, there was no change in smoking behavior. CONCLUSIONS: The applied approach is feasible and able to improve important smoking-related norm perceptions of student nurses and perception of social support. However, additional context measures to influence the settings of nursing education currently rather supporting smoking seem to be necessary in order to promote smoking cessation among nursing students and to scale up implementation of the program. PMID- 27710826 TI - "A stressful and frightening experience"? Children's nurses' perceived readiness to care for children with cancer following pre-registration nurse education: A qualitative study. AB - BACKGROUND: In the UK children with cancer are cared for by children's nurses in a variety of settings, specialist and non-specialist. Whilst post-registration specialist education is available to some nurses, many nurses rely solely on pre registration education to competently care for these children. This study explores whether nurses perceive that this adequately prepares them. OBJECTIVES: To explore the extent to which qualified nurses perceive that pre-registration nurse education prepares them to care for children with cancer; to consider the implications for children's nursing pre-registration curricula. DESIGN: A small scale qualitative study was undertaken using an interpretivist approach. METHODS: Semi-structured interviews were conducted with six qualified children's nurses in two clinical areas - a specialist children's cancer inpatient ward, and a general children's ward where inpatients included children with cancer. RESULTS: Findings are discussed in relation to three emergent themes: Learning in Theory and Practice, Care of the Child and Family, and Resilience. Participants attached significance to the quantity and quality of practice experience. They reflected on barriers to specific and transferable theoretical learning and stressed the importance of integrating theory and practice. Understanding of family-centred care formed a significant part of their preparation. Preconceptions, communication with families and the emotional impact of this speciality were stressful. Improved pre-registration preparation may have developed participants' resilience. CONCLUSION: The complexities of caring for children with cancer and their families require well-prepared nurses. Participants' perceptions of preparedness were influenced by aspects of pre-registration education. Their experiences suggest that curricula should be practice-focused and include a range of placements. Specialist theoretical content must be integrated with practice and transferability of knowledge and skills made explicit. Reflection and problem based learning may foster coping mechanisms and resilience that will equip them to care for children with cancer. PMID- 27710825 TI - Assessing Learning Styles of Graduate Entry Nursing Students as a Classroom Research Activity: A quantitative research study. AB - BACKGROUND: A number of studies across different disciplines have investigated students' learning styles. Differences are known to exist between graduate and baccalaureate nursing students. However, few studies have investigated the learning styles of students in graduate entry nursing programs. . OBJECTIVES: Study objective was to describe graduate entry nursing students' learning styles. DESIGN/SETTING/PARTICIPANTS/METHODS: A descriptive design was used for this study. The Index of Learning Styles (ILS) was administered to 202 graduate entry nursing student volunteers at a southwestern university. Descriptive statistics, tests of association, reliability, and validity were performed. Graduate nursing students and faculty participated in data collection, analysis, and dissemination of the results. RESULTS: Predominant learning styles were: sensing - 82.7%, visual - 78.7%, sequential - 65.8%, and active - 59.9%. Inter-item reliabilities for the postulated subscales were: sensing/intuitive (alpha=0.70), visual/verbal (alpha=0.694), sequential/global (alpha=0.599), and active/reflective (alpha=0.572). Confirmatory factor analysis for results of validity were: chi2(896)=1110.25, p<0.001, CFI=0.779, TLI=0.766, WRMR=1.14, and RMSEA =0.034. CONCLUSIONS: Predominant learning styles described students as being concrete thinkers oriented toward facts (sensing); preferring pictures, diagrams, flow charts, demonstrations (visual); being linear thinkers (sequencing); and enjoying working in groups and trying things out (active),. The predominant learning styles suggest educators teach concepts through simulation, discussion, and application of knowledge. Multiple studies, including this one, provided similar psychometric results. Similar reliability and validity results for the ILS have been noted in previous studies and therefore provide sufficient evidence to use the ILS with graduate entry nursing students. This study provided faculty with numerous opportunities for actively engaging students in data collection, analysis, and dissemination of results. PMID- 27710827 TI - The importance of matching the evaluation population to the intervention population: Using Medicaid data to reach hard-to-reach intervention populations. AB - Subject recruitment is a challenge for researchers and evaluators, particularly with populations that are traditionally hard to reach and involve in research, such as low-income and minority groups. However, when the evaluation sample does not reflect a program's intended audience, the discrepancy may lead to evaluation results that are not valid for that audience. We conducted evaluation activities for a state Supplemental Nutrition Assistance Program-Education (SNAP-Ed) intervention that promotes consumption of fruits and vegetables (F&V) in low income areas. Previous program evaluations efforts had failed to obtain a sufficient proportion of individuals identified as low-income based on their participation in SNAP. We used state Medicaid data as a means of identifying low income families to recruit for a telephone survey (n=311) and an in-depth qualitative interview (n=30) that we designed for the program being evaluated. We chose to focus on the dynamics of parent-child communication around F&V because we considered this previously unevaluated component of the intervention vital to understanding program effectiveness. Our results indicated that the Medicaid database provided an appropriate sample and that parents reported frequent F&V requests from their children. Parents also reported that they would positively respond to requests in many different settings, such as grocery stores (92.6%), restaurants (88.1%), and fast food restaurants (80.4%). PMID- 27710828 TI - Biological and structural studies of phosphonium 'masked thiolate' compounds. AB - The ability of phosphonium cations to act as intracellular transport vectors is well-established. Phosphonioalkylthiosulfate zwitterions, and omega thioacetylalkylphosphonium salts, which act as 'masked thiolate' ligands, are useful precursors for the formation of phosphonium-functionalised gold nanoparticles, enabling the nanoparticles to be transported into cells for diagnostic and therapeutic purposes. In this study we have completed cytotoxicity studies of omega-thioacetylpropylphosphonium salts derived from triphenylphosphine and tri(4-fluorophenyl)phosphine, which show that the compounds are only toxic towards PC3 prostate cancer cells at high concentrations and at prolonged incubation periods and display IC50 values of 67 MUM and 252 MUM respectively, significantly higher than those of other phosphonium salts. MALDI TOF-MS has been used to investigate the uptake of the compounds by PC3 cells and to quantify detectable levels of the compounds inside the cells. The structures of omega-thioacetylpropyl(tri-4-fluorophenyl) phosphonium bromide and the corresponding tri(4-fluorophenyl)phosphoniopropylthiosulfate zwitterion have been investigated by single crystal X-ray crystallography. The results show that molecules of the zwitterion are held together through an extensive array of electrostatic and non-covalent interactions. The unit cell of omega thioacetylpropyl(tri-4-fluorophenyl)phosphonium bromide contains eight cations together with eight bromide anions and two waters of crystallisation, all held together through a complex network of hydrogen bonds. The differences in the molecular packing of the two compounds may account for the lower solubility of the zwitterion in aqueous solutions, compared with that of the phosphonium salt. PMID- 27710829 TI - Eliciting regret improves decision making at the end of life. AB - INTRODUCTION: Management choices at the end of life are high-stake decisions fraught with emotions, chief among is regret. Our objective in this paper is to test the utility of a regret-based model to facilitate referral to hospice care while helping patients clarify their preferences on how they wish to spend the remaining days of their lives. METHODS: A prospective cohort study that enrolled consecutive adult patients (n = 178) aware of the terminal nature of their disease. The patients were at the point in care where they had to decide between continuing potentially 'curative/life-prolonging' treatment (Rx) versus hospice care. Preferences were elicited using a Dual Visual Analog Scale regarding the level of regret of omission versus commission (RgO/RgC) towards hospice care and Rx. Each patient's RgO/RgC was contrasted against the predictive probability of death to suggest a management plan, which was then compared with the patient's actual choice. The probability of death was estimated using validated Palliative Performance Scale predictive model. RESULTS: Eighty-five percent (151/178) of patients agreed with the model's recommendations (p < 0.000001). Model predicted the actual choices for 72% (128/178) of patients (p < 0.00001). Logistic regression analysis showed that people who were initially inclined to be referred to hospice and were predicted to choose hospice over disease-directed treatment by the regret model have close to 98% probability of choosing hospice care at the end of their lives. No other factors (age, gender, race, educational status and pain level) affected their choice. CONCLUSIONS: Using regret to elicit choices in the end-of-life setting is both descriptively and prescriptively valid. People with terminal disease who are initially inclined to choose hospice and do not regret such a choice will select hospice care with high level of certainty.

AB - 6-C-(E-phenylethenyl)naringenin (6-CEPN) is a small molecule found in naringenin fortified fried beef. It has been shown to suppress colon cancer cell proliferation, but the underlying mechanisms are not fully understood. Here we demonstrate that 6-CEPN suppresses tumour cell proliferation through cell cycle arrest in G1 phase, induces necrotic cell death and autophagy in colon cancer cells. Blockade of autophagy by knockdown of the essential autophagy proteins, Atg7 or beclin-1, resulted in aggravated cell death in response to 6-CEPN treatment. In addition, genome-wide transcriptome expression profiling by RNA sequencing revealed that 6-CEPN-mediated gene expression pattern was extremely similar to the transcriptome response induced by a RAS inhibitor salirasib (farnesylthiosalicylic acid [FTS; salirasib]). Subsequent molecular biological and biochemical experiments demonstrated that 6-CEPN indeed strongly inhibited RAS activation, leading to the inhibition of the downstream effector pathways c Raf/mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase kinase and phosphoinositide 3-kinase/AKT/mammalian target of rapamycin. More importantly, our computational molecular docking data showed that 6-CEPN could bind to the active site of isoprenylcysteine carboxyl methyltransferase (Icmt), a critical enzyme for the activation of RAS. Icmt activity assay showed that 6-CEPN inhibited its activity significantly. Knockdown of Icmt by siRNA attenuated 6 CEPN-mediated autophagy and cell death. The present study demonstrates that 6 CEPN induces cell growth inhibition and cytoprotective autophagy in colon cancer cells, at least in part, though inhibition of the Icmt/RAS signalling pathways.

AB - Microscale surface roughness has been shown to enhance osseointegration of titanium implants through increased osteoblast differentiation while osteoblast proliferation remains greater on smooth titanium. Taking advantage of these phenomena, we developed a shape memory (meth)acrylate copolymer with thermomechanical properties that created a time-dependent dynamic surface change from smooth to rough under in vitro cell culture conditions and evaluated the effect of the shape recovery on osteoblast response. Rough topographies were created using soft lithography techniques to mimic those found on clinically-used Ti surfaces (machined smooth; acid-etched; grit-blasted). The surface roughness was then reduced to smooth via compression and shown to fully recover within 24 h in culture conditions. When grown under static conditions, osteoblast number, alkaline phosphatase specific activity (ALP), and osteoprotegerin (OPG) and vascular endothelial growth factor (VEGF) production were unaffected by polymer surface roughness, but osteocalcin (OCN) was increased on the grit-blasted polymer mimic. Under dynamic conditions, DNA was reduced but OCN and OPG were increased on the compressed grit-blasted polymer at 3 days compared to static surfaces. The present study indicates that responses to polymer surface are sensitive to time-dependent changes in topography. The use of a shape memory polymer with dynamic surface roughness may improve osseointegration.

AB - The exploration of stimuli-responsive nano-theranostics provides powerful tools for simultaneously enhancing the accuracy and efficiency of cancer therapies. Herein, we develop mono-dispersed CaCO3 nanoparticles modified with polyethylene glycol (PEG) as a multifunctional nano-carrier for efficient loading of both Mn2+ chelated chlorin e6 (Ce6(Mn)) as a photosensitizer, and doxorubicin (DOX) as a chemotherapy drug. Our CaCO3@Ce6(Mn)-PEG(DOX) nanoparticles, while being stable under physiological pH at 7.4, appear to be highly sensitive to reduced pH and would be rapidly degraded under slightly acidic environment, effectively releasing loaded therapeutic agents. Interestingly, owing to released Ce6(Mn), those nanoparticles show an interesting pH-dependent T1 signal enhancement under magnetic resonance (MR) imaging, which could be utilized for real-time monitoring of drug release. As discovered by MR and fluorescence imaging, intravenously (i.v.) injected CaCO3@Ce6(Mn)/DOX-PEG could gradually accumulate in the tumor, contributing to a superior synergistic anti-tumor effect in the combined photodynamic & chemotherapy. In conclusion, we have developed a tumor-pH activated nanocarrier based on biodegradable CaCO3 nanoparticles, which may be an ideal cancer theranostic nanoplatform with substantial potential for future clinical translation.

AB - Engineering cardiac tissues and organ models remains a great challenge due to the hierarchical structure of the native myocardium. The need of integrating blood vessels brings additional complexity, limiting the available approaches that are suitable to produce integrated cardiovascular organoids. In this work we propose a novel hybrid strategy based on 3D bioprinting, to fabricate endothelialized myocardium. Enabled by the use of our composite bioink, endothelial cells directly bioprinted within microfibrous hydrogel scaffolds gradually migrated towards the peripheries of the microfibers to form a layer of confluent endothelium. Together with controlled anisotropy, this 3D endothelial bed was then seeded with cardiomyocytes to generate aligned myocardium capable of spontaneous and synchronous contraction. We further embedded the organoids into a specially designed microfluidic perfusion bioreactor to complete the endothelialized-myocardium-on-a-chip platform for cardiovascular toxicity evaluation. Finally, we demonstrated that such a technique could be translated to human cardiomyocytes derived from induced pluripotent stem cells to construct endothelialized human myocardium. We believe that our method for generation of endothelialized organoids fabricated through an innovative 3D bioprinting technology may find widespread applications in regenerative medicine, drug screening, and potentially disease modeling.

AB - Uterine disease such as metritis is associated with multiple bacterial infections in the uteri after parturition. However, treatment of metritis is challenging due to considerably high antibiotic treatment failure rate with unknown reason. Recently, chitosan microparticles (CM) have been developed to exert broad spectrum antimicrobial activity against bacterial pathogens, including multi-drug resistant bacteria, without raising CM resistant mutants. In this study, we tested, using metagenomics analysis, if CM maintain strong antimicrobial activity against pathogenic bacteria such as Fusobacteriaceae and Bacteroidaceae in cow uteri and evaluated CM's potency as an alternative antimicrobial agent to cure metritis in cows. Here, we report that efficacy of CM treatment for metritis was comparable to the antibiotic ceftiofur, and CM greatly altered uterine microflora of sick animals to healthy uterine microflora. Among uterine bacteria, CM significantly decreased Fusobacterium necrophorum, which is known pathogenic bacteria within the uterus. Taken together, we observed the broad spectrum antimicrobial activity of CM in vivo with an animal model, and further evaluated treatment efficacy in cows with metritis, providing insights into promising use of CM as an alternative antimicrobial agent for controlling uterine disease. PMID- 27710835 TI - Intolerance of uncertainty and post-traumatic stress symptoms: An investigation within a treatment seeking trauma-exposed sample. AB - BACKGROUND: Intolerance of uncertainty (IU) has been associated with post traumatic stress symptoms (PTSS) in the literature. However, no research to date has investigated the relationship between IU and PTSS within a clinical trauma exposed sample, which is an important next step in the literature and crucial for the generalizability of these findings. Therefore, the current study hypothesized that IU would be related to increased PTSS within a clinical sample of trauma exposed individuals. Further, we hypothesized that IU would be related to elevated PTSS after accounting for anxiety sensitivity (AS) and negative affect (NA), two known correlates of PTSS. Finally, we examined the relations between IU and the PTSS clusters (i.e., avoidance, emotional numbing, hyperarousal, and re experiencing) while covarying for AS and NA. METHODS: Participants included community adults (n=126) presenting at an outpatient clinic. All participants had previously experienced a traumatic event as defined by the DSM-5 PTSD Criterion A. METHODS: Results revealed that IU was significantly associated with increased PTSS above and beyond AS and NA. Further, results indicated that IU was significantly related to the avoidance, hyperarousal, and emotional numbing PTSS clusters, even after covarying for AS and NA. IU was not significantly associated with the PTSS re-experiencing cluster once AS and NA were taken into account. CONCLUSIONS: Our results expand upon the extant literature by demonstrating that IU is associated with PTSS above and beyond AS and NA within a clinical trauma exposed sample. These findings are discussed in terms of promising directions for future research and treatment strategies. PMID- 27710836 TI - Biologically-variable rhythmic auditory cues are superior to isochronous cues in fostering natural gait variability in Parkinson's disease. AB - INTRODUCTION: Rhythmic auditory cueing improves certain gait symptoms of Parkinson's disease (PD). Cues are typically stimuli or beats with a fixed inter beat interval. We show that isochronous cueing has an unwanted side-effect in that it exacerbates one of the motor symptoms characteristic of advanced PD. Whereas the parameters of the stride cycle of healthy walkers and early patients possess a persistent correlation in time, or long-range correlation (LRC), isochronous cueing renders stride-to-stride variability random. Random stride cycle variability is also associated with reduced gait stability and lack of flexibility. METHOD: To investigate how to prevent patients from acquiring a random stride cycle pattern, we tested rhythmic cueing which mimics the properties of variability found in healthy gait (biological variability). PD patients (n=19) and age-matched healthy participants (n=19) walked with three rhythmic cueing stimuli: isochronous, with random variability, and with biological variability (LRC). Synchronization was not instructed. RESULTS: The persistent correlation in gait was preserved only with stimuli with biological variability, equally for patients and controls (p's<0.05). In contrast, cueing with isochronous or randomly varying inter-stimulus/beat intervals removed the LRC in the stride cycle. Notably, the individual's tendency to synchronize steps with beats determined the amount of negative effects of isochronous and random cues (p's<0.05) but not the positive effect of biological variability. CONCLUSION: Stimulus variability and patients' propensity to synchronize play a critical role in fostering healthier gait dynamics during cueing. The beneficial effects of biological variability provide useful guidelines for improving existing cueing treatments. PMID- 27710837 TI - The influence of the aquatic environment on the control of postural sway. AB - Balance training in the aquatic environment is often used in rehabilitation practice to improve static and dynamic balance. Although aquatic therapy is widely used in clinical practice, we still lack evidence on how immersion in water actually impacts postural control. We examined how postural sway measured using centre of pressure and trunk acceleration parameters are influenced by the aquatic environment along with the effects of visual information. Our results suggest that the aquatic environment increases postural instability, measured by the centre of pressure parameters in the time-domain. The mean velocity and area were more significantly affected when individuals stood with eyes closed in the aquatic environment. In addition, a more forward posture was assumed in water with eyes closed in comparison to standing on land. In water, the low frequencies of sway were more dominant compared to standing on dry land. Trunk acceleration differed in water and dry land only for the larger upper trunk acceleration in mediolateral direction during standing in water. This finding shows that the study participants potentially resorted to using their upper trunk to compensate for postural instability in mediolateral direction. Only the lower trunk seemed to change acceleration pattern in anteroposterior and mediolateral directions when the eyes were closed, and it did so depending on the environment conditions. The increased postural instability and the change in postural control strategies that the aquatic environment offers may be a beneficial stimulus for improving balance control. PMID- 27710838 TI - BET bromodomain inhibition reduces maturation and enhances tolerogenic properties of human and mouse dendritic cells. AB - Transcription of inflammatory genes is tightly regulated by acetylation and deacetylation of histone tails. An inhibitor of the acetylated-lysine reader bromodomain and extra-terminal domain (BET) proteins, I-BET151, is known to counteract the induction of expression of inflammatory genes in macrophages. We have investigated the effects of I-BET151 on dendritic cell function, including expression of co-stimulatory molecules and cytokines, and capacity for T cell activation. Treatment of mouse bone marrow derived dendritic cells (BMDC) and human monocyte derived DCs (mdDC) with I-BET151 reduced LPS-induced expression of co-stimulatory molecules, as well as the production of multiple cyokines and chemokines. Most strikingly, secretion of IL-6, IL-12 and IL-10 was significantly reduced to 89.7%, 99.9% and 98.6% respectively of that produced by control cells. I-BET151-treated mdDC showed a reduced ability to stimulate proliferation of autologous Revaxis-specific T cells. Moreover, while I-BET151 treatment of BMDC did not affect their ability to polarise ovalbumin specific CD4+ CD62L+ naive T cells towards Th1, Th2, or Th17 phenotypes, an increase in Foxp3 expressing Tregs secreting higher IL-10 levels was observed. Suppression assays demonstrated that Tregs generated in response to I-BET151-treated BMDC displayed anti-proliferative capacity. Finally, evidence that I-BET151 treatment can ameliorate inflammation in vivo in a T cell dependent colitis model is shown. Overall, these results demonstrate marked effects of BET inhibition on DC maturation, reducing their capacity for pro-inflammatory cytokine secretion and T cell activation and enhancing the potential of DC to induce Foxp3 expressing Treg with suppressive properties.

AB - Multiple sclerosis (MS) is a chronic autoimmune inflammatory demyelinating disorder of the central nervous system (CNS), which causes severe disability and requires extensive medical attention and treatment. While the infiltration of pathogenic immune cells into the CNS leads to the formation of inflammatory lesions in its initial relapsing-remitting stage, late stages of MS are characterized by progressive neuronal loss and demyelination even without continued interaction with the peripheral immune compartment. Several genetic and environmental factors modulate and influence these processes on multiple levels. Genetic variants confer a predisposition for the development of MS, but are not accessible to therapeutic intervention as of today. However, migration studies suggest that environmental factors influence disease development, activity and progression. This article reviews mechanisms of disease pathogenesis in MS and their modulation by environmental factors such as geographical localization, the gut microbiome and the diet. PMID- 27710840 TI - Macrophages and dendritic cells in islets of Langerhans in diabetic autoimmunity: a lesson on cell interactions in a mini-organ. AB - Islets of Langerhans of all species harbor a small number of resident macrophages. These macrophages are found since birth, do not exchange with blood monocytes, and are maintained by a low level of replication. Under steady state conditions, the islet macrophages are in an activated state. Islet macrophages have an important homeostatic role in islet physiology. At the start of the autoimmune process in the NOD mouse, a small number of CD103+ dendritic cells (DC) are found at about the same time that CD4+ T cells also appear in islets. In the absence of the CD103+ DC in the Batf3 deficient mice, autoimmunity never develops. We discuss the interactions among the two phagocytes and beta cells that result in autoimmune diabetes in NOD mice. PMID- 27710841 TI - Removal naturally occurring radionuclides from drinking water using a filter specifically designed for Drinking Water Treatment Plants. AB - The occurrence of naturally occurring radionuclides in drinking water can pose health hazards in some populations, especially taking into account that routine procedures in Drinking Water Treatment Plants (DWTPs) are normally unable to remove them efficiently from drinking water. In fact, these procedures are practically transparent to them, and in particular to radium. In this paper, the characterization and capabilities of a patented filter designed to remove radium from drinking water with high efficiency is described. This filter is based on a sandwich structure of silica and green sand, with a natural high content manganese oxide. Both sands are authorized by Spanish authorities to be used in Drinking Water Treatment Plants. The Mn distribution in the green sand was found to be homogenous, thus providing a great number of adsorption sites for radium. Kinetic studies showed that the 226Ra adsorption on green sand was influenced by the content of major cations solved in the treated water, but the saturation level, about 96-99%, was not affected by it. The physico-chemical parameters of the treated water were unaltered by the filter. The efficiency of the filter for the removal of 226Ra remained unchanged with large water volumes passed through it, proving its potential use in DWTP. This filter was also able to remove initially the uranium content due to the presence of Fe2O3 particles in it, although it is saturated faster than radium.

AB - Recently, deep eutectic solvents (DESs) have shown their new and interesting ability for chemistry through their involvement in variety of applications. This study introduces carbon nanotubes (CNTs) functionalized with DES as a novel adsorbent for Hg2+ from water. Allyl triphenyl phosphonium bromide (ATPB) was combined with glycerol as the hydrogen bond donor (HBD) to form DES, which can act as a novel CNTs functionalization agent. The novel adsorbent was characterized using Raman, FTIR, XRD, FESEM, EDX, BET surface area, TGA, TEM and Zeta potential. Response surface methodology was used to optimize the removal conditions for Hg2+. The optimum removal conditions were found to be pH 5.5, contact time 28 min, and an adsorbent dosage of 5 mg. Freundlich isotherm model described the adsorption isotherm of the novel adsorbent, and the maximum adsorption capacity obtained from the experimental data was 186.97 mg g-1. Pseudo second order kinetics describes the adsorption rate order. PMID- 27710844 TI - A geospatial analysis of soil lead concentrations around regional Oklahoma airports. AB - Lead has been banned from automobile gasoline since 1995; however, lead is still used as an additive to aviation gasoline (avgas). Airports are now one of the greatest sources of lead air emission in the US. The objectives of this study were (1) to evaluate soil lead levels radially from three regional airports; (2) collect historical meteorological data; (3) examine the soil organic matter content and (4) develop correlation coefficients to evaluate correlations among variables. Soil samples were collected from 3 different airports in Oklahoma and the soil lead concentration was measured using x-ray fluorescence (XRF). The measured soil lead concentrations were plotted with the corresponding GPS location in ArcGIS and Inverse Distance Weight spatial analysis was used to create modeled isopleths of soil lead concentrations. One of the three airports was found to have soil lead concentrations that correlate with soil organic matter with one other showing correlation between soil lead concentration and distance from the airport. The spatial modeled isopleths showed elevated soil lead concentrations in the direction of prevailing winds with "hot spots" near the avgas fueling stations. PMID- 27710843 TI - Identification of metabolites produced during the complete biodegradation of 1 butyl-3-methylimidazolium chloride by an enriched activated sludge microbial community. AB - Ionic liquids (ILs) are highly polar solvents with unique physicochemical properties that make them promising green alternatives to volatile organic solvents. Since ILs can be toxic to organisms, the development of methods to degrade ILs into harmless molecules prior to disposal is critical to enhancing their green properties. In this study, metabolites generated during the biodegradation of 1-butyl-3-methylimidazolium chloride (BMIMCl) by an enriched, activated sludge microbial community were investigated. Biodegradation of BMIM and the metabolic products released into the growth media were examined using 1H NMR spectroscopy and mass spectrometry. To the best of our knowledge, this is the first reported complete primary catabolism of the biodegradation-resistant BMIMCl ionic liquid. The bacterial community responsible for degradation was analyzed using a 16S-rRNA amplicon approach. Although the community was diverse, Bacteroidetes was the predominant phylum. The study provides a greater insight into imidazolium-based IL biodegradability and a means to proactively prevent the ecotoxicity of the BMIM cation and its metabolites, by complete primary biodegradation of the cation and removal of most resulting metabolites, prior to release into aquatic waste streams. PMID- 27710845 TI - UV-initiated template copolymerization of AM and MAPTAC: Microblock structure, copolymerization mechanism, and flocculation performance. AB - Flocculation as the core technology of sludge pretreatment can improve the dewatering performance of sludge that enables to reduce the cost of sludge transportation and the subsequent disposal costs. Therefore, synthesis of high efficiency and economic flocculant is remarkably desired in this field. This study presents a cationic polyacrylamide (CPAM) flocculant with microblock structure synthesized through ultraviolet (UV)-initiated template copolymerization by using acrylamide (AM) and methacrylamido propyl trimethyl ammonium chloride (MAPTAC) as monomers, sodium polyacrylate (PAAS) as template, and 2,2'-azobis [2-(2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as photoinitiator. The microblock structure of the CPAM was observed through nuclear magnetic resonance (1H NMR and 13C NMR) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM) analyses. Furthermore, thermogravimetric/differential scanning calorimetry (TG/DSC) analysis was used to evaluate its thermal decomposition property. The copolymerization mechanism was investigated through the determination of the binding constant MK and study on polymerization kinetics. Results showed that the copolymerization was conducted in accordance with the I (ZIP) template polymerization mechanism, and revealed the coexistence of bimolecular termination free-radical reaction and mono-radical termination in the polymerization process. Results of sludge dewatering tests indicated the superior flocculation performance of microblock flocculant than random distributed CPAM. The residual turbidity, filter cake moisture content, and specific resistance to filtration reached 9.37 NTU, 68.01%, and 6.24 (1012 m kg-1), respectively, at 40 mg L-1 of template poly(AM-MAPTAC) and pH 6.0. Furthermore, all flocculant except commercial CPAM showed a wide scope of pH application. PMID- 27710847 TI - Application of steel slag coated with sodium hydroxide to enhance precipitation coagulation for phosphorus removal. AB - Phosphorus removal has been studied for decades to reduce the environmental impact of phosphorus in natural waterbodies. Slag has been applied for the phosphorus removal by several mechanisms. In this study, sodium hydroxide coating was applied on the slag surface to enhance the efficiency of precipitation coagulation process. In the batch test, it was found that the capacity of the slag to maintain high pH decreases with increasing its exposure time to the aqueous solution. In the column test, the coarse-grained coated slag showed higher phosphorus removal efficiency than the fine-grained uncoated slag. The coated slag maintained pH higher than uncoated slag and, accordingly, the removal efficiency of phosphorus was higher. Especially, when pH was less than 8, the removal efficiency decreased significantly. However, coated slag provided an excess amount of aluminum and sodium. Thus, a return process to reuse aluminum and sodium as a coagulant was introduced. The return process yields longer lifespan of slag with higher phosphorus removal and lower concentration of cations in the effluent. With the return process, the phosphorus removal efficiency was kept higher than 60% until 150 bed volumes; meanwhile, the efficiency without return process became lower than 60% at 25 bed volumes. PMID- 27710846 TI - Heavy metals in intensive greenhouse vegetable production systems along Yellow Sea of China: Levels, transfer and health risk. AB - Recently, greenhouse vegetable production (GVP) has grown rapidly and counts a large proportion of vegetable production in China. In this study, the accumulation, health risk and threshold values of selected heavy metals were evaluated systematically. A total of 120 paired soil and vegetable samples were collected from three typical intensive GVP systems along the Yellow Sea of China. Mean concentrations of Cd, As, Hg, Pb, Cu and Zn in greenhouse soils were 0.21, 7.12, 0.05, 19.81, 24.95 and 94.11 mg kg-1, respectively. Compared to rootstalk and fruit vegetables, leafy vegetables had relatively high concentrations and transfer factors of heavy metals. The accumulation of heavy metals in soils was affected by soil pH and soil organic matter. The calculated hazard quotients (HQ) of the heavy metals by vegetable consumption decreased in the order of leafy > rootstalk > fruit vegetables with hazard index (HI) values of 0.61, 0.33 and 0.26, respectively. The HI values were all below 1, which indicates that there is a low risk of greenhouse vegetable consumption. Soil threshold values (STVs) of heavy metals in GVP system were established according to the health risk assessment. The relatively lower transfer factors of rootstalk and fruit vegetables and higher STVs suggest that these types of vegetables are more suitable for cultivation in greenhouse soils. This study will provide an useful reference for controlling heavy metals and developing sustainable GVP. PMID- 27710848 TI - Ecological effect and risk towards aquatic plants induced by perfluoroalkyl substances: Bridging natural to culturing flora. AB - In the present study, the concentrations and proportions of perfluoroalkyl substances (PFASs) in water and sediments (in different seasons) from the Qing River were investigated. The highest concentration of PFASs in water (207.59 ng L 1) was found in summer. The composition of PFASs in water changed with time, perfluorobutane sulfonate (PFBS) was the predominant compound in spring and summer, while long-chain PFASs, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), started to increase in autumn and winter. The PFASs concentration in sediments ranged from 0.96 to 4.05 ng g-1 dw. The proportion of long-chain PFASs was higher than that of short-chain PFASs in sediments, the dominant component in sediments was PFOA with a contribution of 24.6-75.4% to total PFASs in sediments, followed by PFOS. The concentrations of PFASs in roots of emergent plants were relatively higher than those in submerged plants. However, the translocation effect of PFASs was not remarkable. Bioaccumulation factors (BAFs) of the aquatic plants indicated the absorption of PFASs were effective. BAFs in submerged plants basically increased with increasing chain length accordingly. In general, aquatic plants had the absorption preference for long-chain PFASs, especially PFOS, which was the predominant compounds in both submerged and emergent plants. Based on the results above, hornworts were selected to be cultivated indoor in the nutrient solution spiked gradient concentrations of PFOS to assess the general ecological risk. The results revealed that hornworts were resistant to PFOS and might be used as remediation flora to eliminate PFOS contamination. PMID- 27710849 TI - Scanning electrochemical microscopy based evaluation of influence of pH on bioelectrochemical activity of yeast cells - Saccharomyces cerevisiae. AB - In this research scanning electrochemical microscopy was applied for the investigation of immobilized yeast Saccharomyces cerevisiae cells. Two redox mediators based system was applied in order to increase the efficiency of charge transfer from yeast cells. 9,10-phenanthrenequinone (PQ) was applied as a lipophilic redox mediator, which has the ability to cross the cell's membrane; another redox mediator was ferricyanide, which acted as a hydrophylic electron acceptor able to transfer electrons from the PQ to the working electrode of SECM. Hill's function was applied to determine the optimal pH for this described SECM based system. The influence of pH on cell viability could be well described by Hill's function. It was determined that at pH 6.5 the PQ has a minimal toxic influence on yeast cells, and the kinetics of metabolic processes in cells as well as electron transfer rate achieved in consecutive action of both redox mediators were appropriate to achieve optimal current signals. PMID- 27710850 TI - Dynamics of nanoparticle diffusion and uptake in three-dimensional cell cultures. AB - This study aims at elucidating the effect of three-dimensional (3D) extracellular matrix on cell behaviour and nanoparticle (NP) diffusion and its consequences on NP cellular uptake mechansims. For this purpose, human dermal fibroblasts (HDF) and human fibrosarcoma (HT1080) cell lines were grown within a 3D collagen gel and exposed to model polystyrene (PS) NPs of controlled size (44 and 100nm). Results indicate that, in 3D, cell morphology dramatically changes compared to standard 2D cultures and NP diffusion within the matrix is hampered by the interaction with the collagen fibres. As a consequence, NP cellular uptake, modeled with equations describing the stoichiometric exchange between NPs and cell membrane, is significantly slowed down in 3D and in the case of 100 nm NPs, in part due to the hampered diffusion of NPs in collagen gel compared to their transport in standard cell culture medium. Furthermore, our outcomes point at a significant contribution of the cytoskeleton assembly, in particular actin microfilaments, in governing the uptake of PS NPs in a 3D environment, and also that the macropinocytosis process is preserved and is mainly involved in the internalization of PS NPs in a 3D environment. However, depending on cell type and nanoparticle size, other endocytic pathways are also implicated when moving from 2D to 3D culture systems. This work highlights the importance of studying the nano-bio interaction in experimental models that resembles in vivo conditions in order to better predict the therapeutic efficacy of drug delivery systems. PMID- 27710851 TI - Cancer mortality among adolescents and young adults: A historical cohort in a reference institution for cancer treatment in Santa Catarina/South of Brazil 2002 2013. AB - OBJECTIVE: To identify factors associated with early mortality from cancer in adolescents and young adults in a reference institution for oncology treatment in Santa Catarina, Brazil. METHODS: We studied a retrospective cohort with an intentional sample of adolescents (ages 15-19) and young adults (ages 20-29) diagnosed with neoplasia. Secondary data were acquired from January 2002 to December 2013. Kaplan-Meier and Cox regression methods were used for survival analysis. Logistical analysis tested the association between early death (lower tertile between diagnosis and death, according to cancer type) and clinical or sociodemographic variables. RESULTS: We included a total of 889 cases with an average age of 23, with similar gender distributions and a predominance of Caucasian ethnicity. Using the Cox framework of proportional risks adjusted for neoplasia types and gender, individuals with non-hematological neoplasia (solid tumors) presented a 47% higher risk of dying when compared with individuals diagnosed with leukemias and lymphomas (HR: 1.47; 95%CI: 1.12-1.93). Chances of death were 31% higher for males than for females (HR: 1.31; 95%CI: 1.02-1.69). When adjusting for type of neoplasia and age (15-24 and 25-29) the risk of death by cancer was 51% greater in individuals diagnosed with non-hematological neoplasia when compared with individuals diagnosed with leukemias and lymphomas (HR: 1.51; 95%CI: 1.15-1.99). The chance of death by cancer in patients under the age of 25 was 33% greater when compared to that in older patients between the ages of 25 and 29 (HR: 1.33; 95%CI: 1.04-1.75). In multiple regression analysis, factors associated with early mortality from cancer were the number of years in school (P=0.011) and time between diagnosis and start of treatment (P<0.001). CONCLUSIONS: The sample studied with a longer period of time between diagnosis and the start of treatment (access to oncology therapy) and with fewer years in school showed that these factors had important roles in early death from cancer for the observed individuals. This must be considered when planning and identifying risk in young cancer patients in order to lower the impact of the disease on mortality for this age group.

AB - Damage to renal tubular and mesangial cells is central to the development of diabetic nephropathy (DN), a complication of diabetes which can lead to renal failure. Mitochondria are the site of cellular respiration and produce energy in the form of ATP via oxidative phosphorylation, and mitochondrial dysfunction has been implicated in DN. Since the kidney is an organ with high bioenergetic needs, we postulated that hyperglycemia causes damage to renal mitochondria resulting in bioenergetic deficit. The bioenergetic profiles and the effect of hyperglycemia on cellular respiration of human primary mesangial (HMCs) and proximal tubular cells (HK-2) were compared in normoglycemic and hyperglycemic conditions using the seahorse bio-analyzer. In normoglycemia, HK-2 had significantly lower basal, ATP-linked and maximal respiration rates, and lower reserve capacity compared to HMCs. Hyperglycemia caused a down-regulation of all respiratory parameters within 4 days in HK-2 but not in HMCs. After 8 days of hyperglycemia, down-regulation of respiratory parameters persisted in tubular cells with compensatory up-regulated glycolysis. HMCs had reduced maximal respiration and reserve capacity at 8 days, and by 12 days had compromised mitochondrial respiration despite which they did not enhance glycolysis. These data suggest that diabetes is likely to lead to a cellular deficit in ATP production in both cell types, although with different sensitivities, and this mechanism could significantly contribute to the cellular damage seen in the diabetic kidney. Prevention of diabetes induced damage to renal mitochondrial respiration may be a novel therapeutic approach for the prevention/treatment of DN.

AB - OBJECTIVE: We evaluated the modified diagnostic criteria for disseminated intravascular coagulation (DIC), which was published by the Japanese Society of Thrombosis and Hemostasis (JSTH), in 274 suspected DIC patients with hematopoietic injury. MATERIALS AND METHODS: The diagnoses of the patients were as follows: DIC (n=125); pre-DIC (n=42) and non-DIC (n=107). The efficacy of the diagnostic criteria for DIC was evaluated using a receiver operating characteristic (ROC) analysis. RESULTS: The area under the curve (ARC) and odd's ratio for the global coagulation test (GCT) scores in the diagnosis of "DIC" were high, while those for the diagnosis of "DIC and pre-DIC" were low, suggesting that the addition of antithrombin (AT) and soluble fibrin (SF)/thrombin antithrobin complex (TAT) was required to diagnose "DIC and pre-DIC". Although the addition of the AT and SF/TAT values to the GCT did not increase its ability to predict a poor outcome, the JSTH's modified diagnostic criteria scores were correlated with the odds ratio for death. DISCUSSION AND CONCLUSION: The JSTH's modified diagnostic criteria for DIC, which included the GCT score, and the AT, and TAT/SF values, were useful for diagnosing DIC and pre-DIC, and predicting a poor outcome. PMID- 27710854 TI - Albendazole as a promising molecule for tumor control. AB - This work evaluated the antitumor effects of albendazole (ABZ) and its relationship with modulation of oxidative stress and induction of DNA damage. The present results showed that ABZ causes oxidative cleavage on calf-thymus DNA suggesting that this compound can break DNA. ABZ treatment decreased MCF-7 cell viability (EC50=44.9 for 24h) and inhibited MCF-7 colony formation (~67.5% at 5MUM). Intracellular ROS levels increased with ABZ treatment (~123%). The antioxidant NAC is able to revert the cytotoxic effects, ROS generation and loss of mitochondrial membrane potential of MCF-7 cells treated with ABZ. Ehrlich carcinoma growth was inhibited (~32%) and survival time was elongated (~50%) in animals treated with ABZ. Oxidative biomarkers (TBARS and protein carbonyl levels) and activity of antioxidant enzymes (CAT, SOD and GR) increased, and reduced glutathione (GSH) was depleted in animals treated with ABZ, indicating an oxidative stress condition, leading to a DNA damage causing phosphorylation of histone H2A variant, H2AX, and triggering apoptosis signaling, which was confirmed by increasing Bax/Bcl-xL rate, p53 and Bax expression. We propose that ABZ induces oxidative stress promoting DNA fragmentation and triggering apoptosis and inducing cell death, making this drug a promising leader molecule for development of new antitumor drugs.

PMID- 27710857 TI - Cancer, other comorbidity, and risk of venous thromboembolism after stroke: a population-based cohort study. AB - INTRODUCTION: The impact of cancer and other comorbidity on the risk of venous thromboembolism (VTE) after stroke is poorly understood. METHODS: We used Danish population-based national databases to conduct a cohort study encompassing 201,025 patients diagnosed with a first-time ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage or unspecified stroke between 1995 and 2012. As a comparison cohort, 983,222 members of the general population were matched to the stroke patients by date of diagnosis, year of birth, sex, and specific comorbidities, using conditions in the Charlson Comorbidity Index and other VTE risk factors. We computed VTE cumulative risks, rates, and rate ratios. We examined the interaction with comorbidity, defined as the excess VTE rates not explained by stroke and comorbidity alone, for up to five years following stroke. RESULTS: Five-year VTE risks were 2.1% and 1.9% in the stroke and comparison cohorts, respectively. Three-month VTE rates peaked at a 5-fold increase (95% confidence interval [CI]: 4.4; 5.2) in stroke patients and remained 13% to 43% increased relative to the general population during subsequent follow-up. During the first three months after stroke, 15% to 33% of the VTE rates were attributable to the interaction between stroke and moderate (2-3) to high (>=4) comorbidity based on Charlson Comorbidity Index scores. Non-metastatic solid tumors and metastatic disease accounted for most observed interaction with stroke, representing 41% and 56% of attributable three-month VTE rates, respectively. No such interaction between comorbidity and stroke was observed during subsequent follow-up. CONCLUSIONS: Comorbidity, particularly cancer, increased the risk of VTE within three months following stroke.

PMID- 27710861 TI - Novel indoline derivatives prevent inflammation and ulceration in dinitro-benzene sulfonic acid-induced colitis in rats. AB - BACKGROUND: In search of safer treatments for inflammatory bowel disease in subjects not responding to, or showing adverse effects to TNF-alpha antagonists, we tested three novel indoline carbamates in the 2,4-dinitrobenzene sulfonic acid (DNBS) model of colitis in rats. The compounds have anti-inflammatory activity in other disease models in mice. METHODS: AN827 (3-(2-(methoxy carbonyl) ethyl) indolin-4-ylethyl methyl) carbamate (0.1 or 1mg/kg), AN680 (3-(2-(methoxy carbonyl) ethyl) indolin-6-ylethyl methyl) carbamate (1.25 or 2.5mg/kg) and AN917 (3-(3-amino propyl) indolin-4-ylethyl methyl) carbamate (1 or 2mg/kg), 5 aminosalycilic acid (5-ASA) (1 or 100mg/kg) or saline (1ml/kg) were administered rectally 1h after intracolonic administration of DNBS, (35mg/kg in 30% alcohol). Disease severity was assessed four days after DNBS administration by change in body weight, colon weight, area of ulceration, myeloid peroxidase (MPO) activity, colonic TNF-alpha, IL-6 and IL-1beta levels. Histopathological scoring was performed after staining colon sections with hematoxylin and eosin and with antibodies to CD68 and CD11b. RESULTS: AN827 (0.1 and 1mg/kg), AN680 (2.5mg/kg) and AN917 (2.0mg/kg) significantly reduced all macroscopic and microscopic parameters of colitis, colonic pro-inflammatory cytokines, TNF-alpha, IL-1beta and IL-6 and MPO activity by about 80%. CONCLUSIONS: The indoline derivatives largely prevented the symptoms of colitis and were 500-50 times more potent and more effective than 5-ASA. It may be worth evaluating them in models of established colitis. Since AN827 is strongly bound by plasma proteins no adverse effects are expected if compound is absorbed into the circulation after rectal administration. PMID- 27710862 TI - Escitalopram affects spexin expression in the rat hypothalamus, hippocampus and striatum. AB - BACKGROUND: Spexin (SPX) is a recently discovered neuropeptide that exhibits a large spectrum of central and peripheral regulatory activity, especially when considered as a potent anorexigenic factor. It has already been proven that antidepressants, including selective serotonin reuptake inhibitors (SSRI), can modulate peptidergic signaling in various brain structures. Despite these findings, there is so far no information regarding the influence of treatment with the SSRI antidepressant escitalopram on brain SPX expression. METHODS: In this current study we measured SPX mRNA and protein expression in the selected brain structures (hypothalamus, hippocampus and striatum) of rats chronically treated with a 10mg/kg dose of escitalopram using quantitative Real-Time PCR and immunohistochemistry. RESULTS: Strikingly, long-term (4 week) drug treatment led to the downregulation of SPX expression in the rat hypothalamus. This supports the hypothesis that SPX may be involved in the hypothalamic serotonin-dependent actions of SSRI antidepressants and possibly also in the central mechanism of body mass increase. Conversely, SPX expression increased in the hippocampus and striatum. CONCLUSIONS: This is the first report of the effects of a neuropsychiatric medication on SPX expression in animal brain. Our findings shed a new light on the pharmacology of antidepressants and may contribute to a better understanding of the alternative mechanisms responsible for antidepressant action. PMID- 27710860 TI - Behavioral, morphometric, and gene expression effects in adult zebrafish (Danio rerio) embryonically exposed to PFOA, PFOS, and PFNA. AB - Perfluoroalkylated substances (PFAS) are a class of persistent anthropogenic chemicals that have been detected worldwide. PFASs consist of fluorinated carbon chains of varying length, terminal groups, and have a number of industrial uses. A previous zebrafish study from our laboratory showed that acute (3-120h post fertilization, 0.02-2.0MUM), waterborne embryonic exposure to these chemicals resulted in chemical specific alterations at 5days post fertilization (dpf), and some effects persisted up to 14 dpf. Using a gene battery consisting of 100 transcripts identified several genes that were up or down regulated. This current study looks at the long-term impacts of PFASs in adult zebrafish using the same exposure regimen. It was hypothesized that sub-lethal exposure of perfluorooctane sulfonate (PFOS), perfluorononanoic acid (PFNA), or perfluorooctane sulfonate (PFOA) in embryonic zebrafish (3-120 hpf) would result in permanent morphometric, gene expression, and behavioral changes in adult fish similar to those observed at 5 and 14 dpf. Zebrafish were exposed to PFOS, PFOA, and PFNA (Control 0MUM, 2.0MUM) for the first five days post fertilization. At six months post fertilization, no PFAS treatment resulted in a significant change in total body length or weight. In terms of behavior, PFNA males showed a reduction in total distance traveled and time of immobility, and an increase in thigmotaxis behavior, aggressive attacks, and preference for the bright section of the tank. PFOS treated males had a reduced aggression behavior, and PFOA females preferred the dark section of the tank. Gene expression of slco2b1, slco1d1, and tgfb1a were analyzed because these transcripts were previously found to be affected by PFAS exposure in 5dpf and 14 dpf zebrafish and resulted in: significant decrease in expression of slco2b1 for both sexes in PFNA and PFOS treated groups, significant decrease of slco1d1 in all treatment groups for females and PFOS and PFOA exposed males, significant increase of tgfb1a in males treated with PFOS and PFNA, and a significant increase of bdnf in all PFAS male groups. This study demonstrates that acute, embryonic exposure (5days) to individual PFASs result in significant biochemical and behavioral changes in young adult zebrafish 6 months after exposure. These three PFASs have long term and persistent impacts following short term embryonic exposure that persists into adulthood. PMID- 27710863 TI - Expression of Alzheimer's disease risk genes in ischemic brain degeneration. AB - We review the Alzheimer-related expression of genes following brain ischemia as risk factors for late-onset of sporadic Alzheimer's disease and their role in Alzheimer's disease ischemia-reperfusion pathogenesis. More recent advances in understanding ischemic etiology of Alzheimer's disease have revealed dysregulation of Alzheimer-associated genes including amyloid protein precursor, beta-secretase, presenilin 1 and 2, autophagy, mitophagy and apoptosis. We review the relationship between these genes dysregulated by brain ischemia and the cellular and neuropathological characteristics of Alzheimer's disease. Here we summarize the latest studies supporting the theory that Alzheimer-related genes play an important role in ischemic brain injury and that ischemia is a needful and leading supplier to the onset and progression of sporadic Alzheimer's disease. Although the exact molecular mechanisms of ischemic dependent neurodegenerative disease and neuronal susceptibility finally are unknown, a downregulated expression of neuronal defense genes like alfa-secretase in the ischemic brain makes the neurons less able to resist injury. The recent challenge is to find ways to raise the adaptive reserve of the brain to overcome such ischemic-associated deficits and support and/or promote neuronal survival. Understanding the mechanisms underlying the association of these genes with risk for Alzheimer's disease will provide the most meaningful targets for therapeutic development to date. PMID- 27710864 TI - The effects of hydrogen sulfide on electrical field stimulation-induced neurogenic contractile responses in isolated rabbit lower esophageal sphincter: Contribution of nitrergic and non-adrenergic non-cholinergic transmission. AB - BACKGROUND: Hydrogen sulfide (H2S) is a gaseous signaling molecule that, similar to nitric oxide (NO), plays an important role as an inhibitor neurotransmitter in the digestive tract. This study aimed to investigate the effect of H2S and to identify neurogenic contraction responses dependent on the electrical field stimulation (EFS) in the isolated lower esophageal sphincters of rabbits. METHODS: An isolated lower esophageal sphincter was placed in an organ bath system and mechanical responses were recorded using a force transducer. The nerve evoked contractile responses were obtained by EFS. The contractile responses were obtained as biphasic "on" and "off" phases seen at the beginning and end of EFS, respectively. RESULTS: Sodium hydrogen sulfide (NaHS) reduced the EFS-mediated "off" phase and the EFS-mediated non-adrenergic non-cholinergic (NANC) "off" phase. NaHS reduced the EFS-mediated "on" phase as well. l-Cysteine reduced the EFS-mediated "off" phase and the EFS-mediated NANC "off" phase. l Propargylglycine (PAG) did not affect the EFS-mediated "off" phase or the EFS mediated NANC "off" phase. NaHS, l-cysteine, and PAG reduced the EFS-mediated, NO independent "off" phase. The effect of NaHS in all of the experiments returned in time. Also, NaHS caused significant relaxation of 80-mM KCl-Krebs solution induced-contractions, while l-cysteine and PAG did not cause a significant relaxation. CONCLUSION: These findings suggest that H2S has an inhibitory effect on the lower esophageal sphincter muscle. While the effect of H2S on EFS-mediated responses disappeared in time, the effect of H2S sustained the KCl-Krebs solution induced contractions. This shows that H2S may have an effect on neurotransmission at the nerve terminal. PMID- 27710865 TI - Hydrocortisone and dexamethasone dose-dependently stabilize mast cells derived from rat peritoneum. AB - BACKGROUND: Besides their anti-inflammatory properties, corticosteroid drugs exert anti-allergic effects. Exocytosis of mast cells is electrophysiologically detected as the increase in the whole-cell membrane capacitance (Cm). Therefore, the lack of such increase after exposure to the drugs suggests their mast cell stabilizing effects. METHODS: We examined the effects of 1, 10, 100 and 200MUM hydrocortisone or dexamethasone on the degranulation from rat peritoneal mast cells. Employing the whole-cell patch-clamp recording technique, we also tested their effects on the Cm during exocytosis. RESULTS: At relatively lower concentrations (1, 10MUM), both hydrocortisone and dexamethasone did not significantly affect the degranulation from mast cells and the increase in the Cm induced by GTP-gamma-S. Nevertheless, at higher doses (100, 200MUM), these drugs inhibited the degranulation from mast cells and markedly suppressed the GTP-gamma S-induced increase in the Cm. CONCLUSIONS: Our results provided electrophysiological evidence for the first time that corticosteroid drugs, such as hydrocortisone and dexamethasone, inhibited the exocytotic process of mast cells in a dose-dependent manner. The mast cell-stabilizing effects of these drugs may be attributable to their "non-genomic" action, by which they exert rapid anti-allergic effects. PMID- 27710866 TI - Identification and functional characterization of HbOsmotin from Hevea brasiliensis. AB - Latex in the laticiferous cell network of Hevea brasiliensis tree is composed of cytoplasm that synthesizes natural rubber. Ethylene stimulation of the tree bark enhances latex production partly by prolonging the duration of latex flow during the tapping process. Here, we identified an osmotin-like cDNA sequence (HbOsmotin) from H. brasiliensis that belongs to the pathogenesis-related 5 (PR 5) gene family. The HbOsmotin protein is present in the lutoids of latex in H. brasiliensis, whereas in onion epidermal cells, this protein is predominantly distributed around the cell wall, suggesting that it may be secreted from the cytoplasm. We investigated the effects of exogenous ethylene on HbOsmotin transcription and protein accumulation in rubber latex, and further determined the protein function after osmotic stress in Arabidopsis. In regularly tapped trees, HbOsmotin expression was drastically inhibited in rubber latex after tapping, although the expression was subsequently recovered by ethylene stimulation. However, in virgin plants that had never been tapped, exogenous ethylene application slightly decreased HbOsmotin expression. HbOsmotin overexpression in Arabidopsis showed that HbOsmotin reduced the osmotic stress tolerance of the plant, which likely occurred by raising the water potential. These data indicated that HbOsmotin may contribute to osmotic regulation in laticiferous cells. PMID- 27710867 TI - Highlighting the microbial diversity of 12 French cheese varieties. AB - Surface-ripened cheeses host complex microbial communities responsible for the transformation of milk into cheese as well as the development of important properties in terms of texture, color and sensory perception. In this study, we used high-throughput amplicon sequencing to decipher the bacterial and fungal diversity of 60 cheeses belonging to 12 popular French cheese varieties. Using this approach, 76 bacterial and 44 fungal phylotypes were identified. Major differences were observed between rind and core samples and also according to cheese varieties and manufacturing processes. Occurrence analysis revealed the presence of widespread taxa as well as operational taxonomic units (OTUs) specific to one or several cheese varieties. Finally, we observed patterns specific to the cheese production facility, supporting the importance of indigenous microorganisms for the microbial assemblage of cheese microbiota. PMID- 27710868 TI - Efficacy and tolerability of brivaracetam compared to lacosamide, eslicarbazepine acetate, and perampanel as adjunctive treatments in uncontrolled focal epilepsy: Results of an indirect comparison meta-analysis of RCTs. AB - BACKGROUND: Brivaracetam (BRV), eslicarbazepine acetate (ESL), lacosamide (LCM), and perampanel (PER) have been recently marketed as adjunctive treatments for focal onset seizures. To date, no randomized controlled trial (RCT) has directly compared BRV with ESL, LCM, or PER. PURPOSE: To compare BRV with the other add-on AEDs in patients with uncontrolled focal epilepsy, estimating their efficacy and tolerability through an adjusted, common-reference based indirect comparison meta analysis. METHODS: We systematically searched RCTs in which add-on treatment with ESL or LCM in patients with focal onset seizures have been compared with placebo. Efficacy and tolerability outcomes were considered. Random-effects Mantel Haenszel meta-analyses were performed to obtain odds ratios (ORs) for the efficacy of BRV, LCM, ESL, or PER versus placebo. Adjusted indirect comparisons were then made between BRV and the other three AEDs using the obtained results, comparing the minimum and the highest effective recommended daily dose of each drug. RESULTS: Seventeen RCTs, with a total of 4971 patients were included. After adjusting for dose-effects, indirect comparisons showed no difference between BRV and LCM, ESL, or PER for responder rate and seizure freedom. Lower adverse events were observed with high dose BRV compared to high dose ESL or PER, but no difference was found in withdrawing because of adverse events. CONCLUSIONS: Indirect comparisons do not demonstrate a significant difference in efficacy between add-on BRV and LCM, ESL, or PER in focal epilepsy, and might suggest a better tolerability of BRV than ESL, and possibly also PER, at the highest effective recommended dose. PMID- 27710869 TI - Plasma proteomics in CML patients before and after initiation of tyrosine kinase inhibitor therapy reveals induced Th1 immunity and loss of angiogenic stimuli. AB - BACKGROUND AND AIMS: The simultaneous measurement of many proteins is now possible using multiplex assays. In this pilot study we investigated a total of 124 proteins in plasma from chronic myeloid leukemia (CML) patients with the purpose of identifying proteins that are differently expressed at diagnosis and after tyrosine kinase inhibitor (TKI) treatment initiation. METHODS: Samples were taken from 14 CML patients at diagnosis and after three months of TKI treatment (imatinib or dasatinib). Samples were analyzed by Mesoscale Discovery, Myriad RBM MAP technology and Olink Proseek. RESULTS: Multiple plasma proteins were differentially expressed before and after initiation of TKI therapy. Protein patterns demonstrated a possible shift towards Th1-immunity and reduced angiogenic stimuli. Further, some plasma proteins were identified that can be of potential interest to study further for biologic, prognostic or therapeutic significance such as E-selectin, uPAR, growth hormone and carbonic anhydrase IX. CONCLUSIONS: Plasma proteomics seems feasible and useful in CML patients, both for studying patterns of protein expression and for identifying single proteins differentially expressed before and after treatment. Plasma proteomics may be useful to map disease activity and biological processes. Hence, plasma proteomics can be used to understand drug mechanisms and treatment responses in CML. PMID- 27710870 TI - Individuals with high obsessive-compulsive tendencies or undermined confidence rely more on external proxies to access their internal states. AB - BACKGROUND AND OBJECTIVES: The Seeking Proxies for Internal States (SPIS) hypothesis predicts that obsessive-compulsive disorder (OCD) is associated with a deficit in subjective convictions, which may lead to a reliance on external substitutes for the perceptions of an individual's internal states. Two well designed studies were performed for the present work that adopted a false bio feedback procedure in a muscle tension task to examine the SPIS hypothesis. METHODS: The false bio-feedback paradigm was used to investigate our hypothesis. NeXus-10 Mark II hardware and V2011 BioTrace + software (Mind Media B.V., Herten, Netherlands) were utilized to measure the muscle tension of the flexor carpiulnaris muscle, which characterized the target's internal state. In addition, false EMG changes were recorded and displayed on a computer monitor and were considered external proxies. RESULTS: Study 1 demonstrated that the participants with high obsessive-compulsive (OC) tendencies were more affected by the false bio-feedback and exhibited lower confidence in their judgments regarding their muscle tension compared with the participants with low OC tendencies. These findings indicate that subjects with high OC tendencies were more influenced by self-perception effects. In contrast, the subjects in the undermined confidence group in Study 2 were more easily influenced by the false bio-feedback compared with the control group, which suggests that the subjects in the undermined confidence group were more affected by self-perception effects. LIMITATIONS: We did not combine the undermined confidence with OC tendencies or OCD symptoms in our paradigm to investigate their joint effects on self perception. CONCLUSIONS: Our findings provide further evidence that supports the SPIS hypothesis, which indicates that OC tendencies and the confidence in an individual's recognition of internal states appear to have similar effects on the assessment of internal states and reliance on proxies. PMID- 27710871 TI - Trabectedin as a chemotherapy option for patients with BRCA deficiency. AB - Trabectedin is a marine-derived product that was originally isolated from the Caribbean sea squirt Ecteinascidia turbinata and the first anticancer marine drug to be approved by the European Union. It is currently used as a single agent for the treatment of patients with soft tissue sarcoma after failure of anthracyclines and ifosfamide, or for those patients who are unsuited to receive these agents, and in patients with relapsed, platinum-sensitive ovarian cancer in combination with pegylated liposomal doxorubicin. Trabectedin has a unique multi faceted mechanism of action that involves transcription regulation and DNA repair systems, including transcription-coupled nucleotide excision repair and homologous recombination repair (HRR) as the main hallmarks of its antiproliferative activity. In addition, trabectedin has shown the ability to modulate the tumor microenvironment. Indeed, the activity of trabectedin is related to altered function and expression of DNA repair genes, such as BRCA1 (BReast-CAncer susceptibility gene 1) and BRCA2. The particular sensitivity of sarcoma, ovarian and breast cancer cells deficient in HRR, previously observed in preclinical models, now has been confirmed in the clinical setting as well, suggesting that BRCA mutations are associated with improved clinical responses to trabectedin. Current efforts are focused on the evaluation of these unique features of trabectedin and on the identification of predictive factors for patients with an objective to determine whether a deficiency of HRR DNA repair pathway could impact the clinical benefit achieved from trabectedin. PMID- 27710872 TI - Pharmacological evaluation of poly(3-methylthiophene) and its titanium(IV)phosphate nanocomposite: DNA interaction, molecular docking, and cytotoxic activity. AB - Cancer and pathogenic microbial diseases have terribly affected human health over a longer period of time. In response to the increasing casualties due to cancer and microbial diseases, unique poly(3-methylthiophene) and poly(3 methylthiophene)-titanium(IV)phosphate composite were prepared via in-situ oxidative chemical polymerization in this work. The poly(3-methylthiophene) and poly(3-methylthiophene)-titanium(IV)phosphate composite were well characterized by Fourier transform infrared spectroscopy and field emission scanning electron microscopy. DNA binding studies by UV-Visible and fluorescence spectroscopic investigations indicated strong binding affinities of poly(3-methylthiophene) and poly(3-methylthiophene)-titanium(IV)phosphate nanocomposite; leading to structural damage of DNA. Poly(3-methylthiophene)-titanium(IV)phosphate nanocomposite showed stronger interactions with DNA as compared to poly(3 methylthiophene) and from dye displacement assay it was confirmed that mode of binding of both the formulations was intercalative. The antimicrobial screening revealed that polymer and its composite displayed stronger antibacterial effects than ampicillin against Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhimurium. Besides, the poly(3-methylthiophene) and poly(3-methylthiophene)-titanium(IV)phosphate nanocomposite showed dose dependent effects towards estrogen receptor positive breast cancer (MCF-7) and estrogen receptor negative breast cancer (MDA-MB-231) cell lines; with poly(3 methylthiophene)-titanium(IV)phosphate nanocomposite showing better activities against both cell lines. In all in-vitro biological investigations, poly(3 methylthiophene)-titanium(IV)phosphate composite showed superior properties to that of the pure poly(3-methylthiophene), which encouraged us to suggest its potential as future therapeutic gear in drug delivery and other allied fields. PMID- 27710873 TI - Short-range ultraviolet irradiation with LED device effectively increases serum levels of 25(OH)D. AB - Impairment of the activities of daily living (ADL) by osteoporosis is an important concern in developed countries with a super-aging population. Vitamin D, which is a crucial molecule in bone metabolism and mainly produced endogenously with ultraviolet (UV) light exposure, is known to be insufficient in the elderly population. We used an UV Light-Emitting Diode (UV-LED) instrument generating a narrow-range wavelength to analyze the efficacy of endogenous vitamin D production. The primary purpose of this study was to examine the effects of UV irradiation at various narrow-range wavelengths using UV-LED on vitamin D supplementation. The second one was to clarify the short-term effects of UV irradiation on bone morphology in mice. Vitamin D-starved C57BL/6 female mice (n=7 per group) were UV-irradiated (268nm, 282nm, 290nm, 305nm, and 316nm) with 1kJ/m2 twice a week for 4weeks. UV irradiation using UV-LED had significant effects on increasing serum 25(OH)D levels in all wavelength groups (P<0.001, all groups) as compared to a control group. Among irradiated groups, wavelength of 316nm had a less marked effect on 25(OH)D production compared with other wavelengths at 1week of UV irradiation (P<0.05). Levels of 1,25(OH)2D were significantly increased after 4weeks irradiation with UV-B or UV-C irradiation (P<0.05). mRNA levels of vitamin D 25-hydroxylase were increased with UV-B or UV C irradiation (268nm-305nm), significantly. Micro-CT examination revealed that short-term (4weeks) UV-irradiation did not induce morphological change of mice in any group. This study provides essential information that narrow-range UV irradiation with LED can increase the endogenous production of vitamin D, and mRNA levels of the responsible enzyme. Although bone morphology was not altered by short-term UV irradiation in this study, an increase of serum vitamin D might improve bone morphology with long-term irradiation. PMID- 27710874 TI - Hyperfuctioning insular thyroid carcinoma: A rare case report. AB - INTRODUCTION: Insular carcinoma of thyroid (ICT) is a rare pattern of thyroid tumor. Being hyperfunctioning makes the condition rarer. Here we reported a case of ICT associated with hyperthyroidism. CASE REPORT: A 65-year-old female presented with neck mass for 4 years. She had symptoms of thyrotoxicosis and received antithyroid treatment. She was referred for surgical management. She had multiple, non tender, mobile masses in the neck. Ultrasound showed midline multiple heterogenous mass lesions with multiple lymph nodes in right side of the neck largest one measuring 2*2cm. The patient was prepared for total thyrodectomy with radical neck dissection. The result of histopathology confirmed unifocal, poorly differentiated ICT. The post operative course was uneventful. CONCLUSION: Insular carcinoma is a rare disease. It may present with long history of signs and symptoms of hyperthyroidism. Total thyroidectomy is the main line of treatment. PMID- 27710875 TI - Biventricular transient systolic dysfunction after mitral valve replacement: Pericardial decompression syndrome. AB - BACKGROUND: Pericardial decompression syndrome is defined as paradoxical hemodynamic instability, left ventricular or bi ventricular systolic dysfunction and pulmonary edema after pericardial fluid drainage. Pericardial Decompression Syndrome is an unexpected clinical scenario with an incidence less than 5% in all surgically or percutaneously managed pericardial tamponade patients. The aim of this manuscript was to describe a case with cardiac tamponade in whom acute biventricular heart failure and pulmonary edema developed after surgical creation of a pericardial window, and to discuss this case in light of the literature. CASE REPORT: A 43-year-old woman who underwent mitral valve replacement three weeks ago admitted to our hospital with dyspnea, tachycardia, and atrial fibrillation. Large quantity of pericardial fluid (35mm in the posterior wall, 25mm in the anterior wall) with partial compression of the right ventricle and 50% left ventricle ejection fraction (LVEF) was determined via transthoracic echocardiography (TTE). After creation of pericardio-pleural window, more than 1000ml of serosanguineous fluid were quickly removed from the pericardial space. During the following hours of the decompression, the patient's condition deteriorated and overt pulmonary edema developed. On the second day, biventricular systolic dysfunction, global diffuse hypokinesia and 15-20% LVEF was observed via TTE. High-dose inotropic support and diuretics was continued. During follow up she was progressively weaned off inotropes, LVEF were raised to 35%. Two weeks later, repeated TTE showed normal biventricular systolic function and LVEF was 50%. CONCLUSION: We recommend gradual removal of pericardial effusion under hemodynamic monitoring, especially in patient with postcardiotomy tamponade. PMID- 27710876 TI - Bilateral simultaneous VATS for complete resection of bilateral posterior mediastinal bronchogenic cyst: A case report. AB - INTRODUCTION: The mediastinal bronchogenic cysts represents 50%-60% of mediastinal cysts and rarely occurs in the posterior mediastinum. The final surgical resection is indicated for symptomatic patients and is recommended for some asymptomatic patients in order to establish the diagnosis and to avoid any subsequent complications. CASE PRESENTATION: We report a case of 17 years-old male suffering from bronchogenic cysts of the mediastinum. The patient was admitted to our hospital complaining with dry chough and dyspnea; CT scan showed a cystic mass in posterior mediastinum. To achieve a correct diagnosis and to prevent the risk of complications, a complete surgical resection was performed by using bilateral simultaneous VATS. DISCUSSION: Bronchogenic cysts manifest as solitary or multiple lesions, majority of which are located in the mediastinum while sometimes can occur in the lung parenchyma. They are usually asymptomatic and casually discovered at chest X-ray or CT scan. The most common complications are infections, pneumothorax and hemoptysis. The complete surgical resection is the only radical and definitive treatment of the bronchogenic mediastinal cysts. VATS permits good exposure of the thoracic cavity including the mediastinum and better evaluation of the anatomic relationship. The absence of intra and postoperative complications, the reduction of pain in the early postoperative period demonstrate the security of this approach. CONCLUSION: Bilateral simultaneous VATS for resection of bilateral posterior mediastinal bronchogenic cyst may be a useful approach. In our case no intra and post-operative complications occurred and patient discharged home on 4 rd day.

AB - PURPOSE: This study aimed to assess the consistency between patients' complaints and their eye diseases. DESIGN: Cross-sectional study. METHODS: RESULTS: The frequencies of at least one newly diagnosed visually important ocular disease were 25.9%, 27.0%, and 45.3% in groups 1, 2, and 3, respectively (p<0.001). The same frequencies were significantly higher in patients >75 years of age compared with the younger group (59.1% vs. 22.0%, p<0.001). Although these values were statistically significant in patients <=75 years of age (p<0.001), they were insignificant in patients >75 years of age according to type of complaints (p=0.773). Patients with diabetes mellitus exhibited significantly lower vision, higher rate of visually important ocular diseases, and higher intraocular pressure readings than patients without diabetes mellitus (p=0.009, 0.015, and 0.002, respectively). CONCLUSIONS: Visually important ocular diseases were diagnosed approximately in a quarter of patients who had no complaints about decrease in vision and in more than half of the oldest geriatric patients (>75years) irrespective of the type of complaints.

AB - Electrical status epilepticus of sleep (ESES), with the activation of profuse amounts of epileptiform discharges in sleep, may lead to intractable epilepsy and neurocognitive decline in children. Numerous varied treatments including antiseizure medications, steroids, and surgery have been investigated as possible treatment options. The ketogenic diet (KD) is an additional treatment option which may add to our treatment armamentarium for ESES. The KD may theoretically improve ESES by affecting GABA systems and reducing inflammation. Clinical reports of the KD for ESES have been heterogeneous, but to date 38 children have been described in six publications. Overall, 53% had EEG improvement, 41% had>50% seizure reduction, 45% had cognitive improvement, but only 9% had EEG normalization. This review will assess the efficacy of the KD in the treatment of ESES based on known data as well as possible mechanisms of action and the need for future study.

PMID- 27710880 TI - Mercury and methylmercury distribution in the intertidal surface sediment of a heavily anthrophogenically impacted saltwater-mangrove-sediment interplay zone. AB - Total mercury (THg) and methylmercury (MeHg) concentrations were determined from sediment samples collected from thirty sampling stations in Port Klang, Malaysia. Three stations had THg concentrations exceeding the threshold effect level of the Florida Department of Environmental Protection and the Canadian interim sediment quality guidelines. THg and MeHg concentrations were found to be concentrated in the Lumut Strait where inputs from the two most urbanized rivers in the state converged (i.e. Klang River and Langat River). This suggests that Hg in the study area likely originated from the catchments of these rivers. MeHg made up 0.06 94.96% of the sediment's THg. There is significant positive correlation (p < 0.01) between THg and MeHg concentrations. Significant positive correlation (p < 0.05) was also observed between fine sediment particles (i.e. clay and silt) with MeHg concentrations. Sediment particle size, however, was not found to have any influence on THg concentrations in the sediment in the study area. PMID- 27710881 TI - Delayed addition of nitrogen-rich substrates during composting of municipal waste: Effects on nitrogen loss, greenhouse gas emissions and compost stability. AB - Municipal waste is usually composted with an N-rich substrate, such as manure, to increase the N content of the product. This means that a significant amount of nitrogen can be lost during composting. The objectives of this study were (i) to investigate the effect of split addition of a nitrogen-rich substrate (poultry manure) on nitrogen losses and greenhouse gas emissions during composting and to link this effect to different bulking agents (coffee husks and sawdust), and (ii) to assess the effect of split addition of a nitrogen-rich substrate on compost stability and sanitisation. The results showed that split addition of the nitrogen-rich substrate reduced nitrogen losses by 9% when sawdust was used and 20% when coffee husks were used as the bulking agent. Depending on the bulking agent used, split addition increased cumulative N2O emissions by 400-600% compared to single addition. In contrast, single addition increased methane emissions by up to 50% compared to split addition of the substrate. Hence, the timing of the addition of the N-rich substrate had only a marginal effect on total non-CO2 greenhouse gas emissions. Split addition of the N-rich substrate resulted in compost that was just as stable and effective at completely eradicating weed seeds as single addition. These findings therefore show that split addition of a nitrogen-rich substrate could be an option for increasing the fertilising value of municipal waste compost without having a significant effect on total greenhouse gas emissions or compost stability. PMID- 27710882 TI - Variability of disinfection by-products at a full-scale treatment plant following rainfall events. AB - The quality of drinking water sources can decrease when contaminants are transported by overland and subsurface flow and discharged into surface waters following rainfall events. Increases in organic contaminants such as road salts and organic matter may occur and potentially modify disinfection by-products (DBPs) concentration and speciation. This study investigated the effects of various spring rainfall events on the quality of treated waters at a large water treatment plant through the implementation of intensive water quality monitoring of raw, filtered and treated waters during different rainfall events. DBPs (four trihalomethanes and six haloacetic acids) and their explanatory variables (pH, turbidity, water temperature, specific ultraviolet absorbance, total and dissolved organic carbon, bromide and chlorine dose) were measured during four rainfall events. The results showed that water quality degrades during and following rainfall, leading to small increases in trihalomethanes (THM4) and haloacetic acids (HAA6) in treated waters. While THM4 and HAA6 levels remained low during the pre-rainfall period (<9 MUg/L) for the four sampling campaigns, small increases in THM4 and HAA6 during and after spring rainfall events were observed. During the rainfall and post-rainfall periods, concentration peaks corresponding to 3-fold and 2-fold increases (respectively 27.5 MUg/L for THM4 and 12.6 MUg/L for HAA6) compared to pre-rainfall levels were also measured. A slight decrease in harmful brominated THM and HAA proportion was also observed following rainfall events.

AB - A microscale discontinuous fermenter was used for anaerobic digestion of wine waste - a hardly gasifiable feedstock material. Efficiency of biogas production, i.e. changes in content of nitrogen, oxygen, carbon dioxide and methane in gas phase, was monitored by gas chromatography/mass spectrometry. Liquid chromatography/high resolution tandem mass spectrometry in combination with principal component analysis and orthogonal projection to latent structures was used to reveal main chemical differences of gasified wine waste mixture from commonly used ones in agricultural biogas plants. Compounds with particular polyphenolic structures appeared among the most distinctive markers. Analysis of samples collected during acidogenic phase and unstabilized methanogenesis indicates formation of certain dihydro-flavonoids in early stages of the process and their consequent degradation. Due to formerly described higher toxicity of some dihydroflavonoids (e.g. taxifolin) compared to their more common counterparts (e.g. quercetin, malvidin etc.), unstabilized digestate would represent a potential environmental risk when used as a fertilizer deserving a proper control. PMID- 27710884 TI - Selective dissolution followed by EDDS washing of an e-waste contaminated soil: Extraction efficiency, fate of residual metals, and impact on soil environment. AB - To enhance extraction of strongly bound metals from oxide minerals and organic matter, this study examined the sequential use of reductants, oxidants, alkaline solvents and organic acids followed by a biodegradable chelating agent (EDDS, [S,S]-ethylene-diamine-disuccinic-acid) in a two-stage soil washing. The soil was contaminated by Cu, Zn, and Pb at an e-waste recycling site in Qingyuan city, China. In addition to extraction efficiency, this study also examined the fate of residual metals (e.g., leachability, bioaccessibility, and distribution) and the soil quality parameters (i.e., cytotoxicity, enzyme activities, and available nutrients). The reductants (dithionite-citrate-bicarbonate and hydroxylamine hydrochloride) effectively extracted metals by mineral dissolution, but elevated the leachability and bioaccessibility of metals due to the transformation from Fe/Mn oxides to labile fractions. Subsequent EDDS washing was found necessary to mitigate the residual risks. In comparison, prior washing by oxidants (persulphate, hypochlorite, and hydrogen peroxide) was marginally useful because of limited amount of soil organic matter. Prior washing by alkaline solvents (sodium hydroxide and sodium bicarbonate) was also ineffective due to metal precipitation. In contrast, prior washing by low-molecular-weight organic acids (citrate and oxalate) improved the extraction efficiency. Compared to hydroxylamine hydrochloride, citrate and oxalate induced lower cytotoxicity (Microtox) and allowed higher enzyme activities (dehydrogenase, acid phosphatase, and urease) and soil nutrients (available nitrogen and phosphorus), which would facilitate reuse of the treated soil. Therefore, while sequential washing proved to enhance extraction efficacy, the selection of chemical agents besides EDDS should also include the consideration of effects on metal leachability/bioaccessibility and soil quality. PMID- 27710885 TI - Removal of natural organic matter (NOM) and its constituents from water by adsorption - A review. AB - Natural organic matter (NOM) is produced through metabolic reactions in water supply in drinking water sources and has been reported to cause several problems including objectionable taste and color of water, formation of disinfection by products (DBPs) and reducing the amount of dissolved oxygen in water. The removal of NOM and its constituents from water is a challenging issue worldwide. Many technologies have been examined for this purpose. The properties and amount of NOM, however, can significantly affect the process efficiency. In the present work, an overview of the recent research studies dealing with adsorption method for the removal of NOM and related compounds from water is presented. A wide variety of conventional and non-conventional adsorbents have been reviewed for their potential in NOM removal from water. As revealed from the literature reviewed, modified adsorbents, composite materials and few nanomaterials have shown promising results for NOM removal from water. The main findings obtained for the removal of NOM using different adsorbents have been discussed in this review. PMID- 27710886 TI - Developmental effects of fipronil on Japanese Medaka (Oryzias latipes) embryos. AB - Pesticides in urban runoff are a major source of pollutants in aquatic ecosystems. Fipronil, a phenylpyrazole insecticide, found in structural pest control products, turf grass control, and home pet flea medication, has recently increased in use and is commonly detected in urban runoff. However, little is known about the effects of fipronil on aquatic organisms at early developmental stages. Here, we evaluated toxicity of fipronil to embryos of Japanese Medaka (Oryzias latipes, Qurt strain) using a high-throughput 96-well plate toxicity test. Male and female embryos (<6 h post fertilization) were exposed to concentrations of fipronil ranging from 0.1 to 910 MUg L-1 for 14 days or until hatching. Embryos were subjected to gross and microscopic examinations of developmental adverse effects as well as transcriptome analysis using RNA-seq. Results indicated a positive dose-response in reduced hatching success, increased gross deformity (tail curvature) at a lowest-observed-effect concentration (LOEC) of 200 MUg L-1 and delayed hatching (~1 day at the highest concentration, LOEC = 600 MUg L-1). The transcriptome analysis indicated that fipronil exposure enhanced expression of titin and telethonin, which are responsible for muscle development. It is therefore possible that the formation of a tail curvature is due to asymmetrical overgrowth of muscle. Our results indicate that sub-lethal effects occur in embryonic stages of an aquatic vertebrate following exposure to high concentrations of fipronil, although no adverse effects at the highest published environmentally relevant concentration (6.3 MUg L-1) were observed. PMID- 27710887 TI - Separation of chlorinated diastereomers of decarboxy-betacyanins in myeloperoxidase catalyzed chlorinated Beta vulgaris L. extract. AB - A comparative chromatographic evaluation of chlorinated decarboxylated betanins and betanidins generated under activity of hypochlorous acid exerted upon these highly antioxidative potent decarboxylated pigments derived from natural sources was performed by LC-DAD-ESI-MS/MS. Comparison of the chromatographic profiles of the chlorinated pigments revealed two different directions of retention changes in relation to the corresponding substrates. Chlorination of all betacyanins that are decarboxylated at carbon C-17 results in an increase of their retention times. In contrast, all other pigments (the non-decarboxylated betacyanins as well as 2-decarboxy- and 15-decarboxy-derivatives) exhibit lower retention after chlorination. During further chromatographic experiments based upon chemical transformation of the related pigments (decarboxylation and deglucosylation), the compounds' structures were confirmed. The elaborated method for determination of chlorinated pigments enabled analysis of a chlorinated red beet root extract that was submitted to the MPO/H2O2/Cl- system acting under inflammation-like conditions (pH 5). This indicates a promising possibility for measurement of these chlorinated pigments as indicators of specific inflammatory states wherein betacyanins and decarboxylated betacyanins act as hypochlorite scavengers. PMID- 27710888 TI - Comparative pharmacokinetic analysis of extracts of crude and wine-processed Dipsacus asper in rats by a sensitive ultra performance liquid chromatography tandem mass spectrometry approach. AB - The purpose of this study is to establish and validate an UPLC-MS/MS approach to determine 4-caffeoylquinic acid, chlorogenic acid, 3,5-dicaffeoylquinic acid, loganic acid, loganin, sweroside, dipsacoside B and asperosaponin VI from extracts of crude and wine-processed Dipsacus asper in biological samples and apply the approach to a comparative pharmacokinetic study. A Waters BEH C18 UPLC column was employed with acetonitrile/0.2% formic acid-water as mobile phases. The mass analysis was carried out in a triple quadrupole mass spectrometer using multiple reaction monitoring (MRM) with negative scan mode. A one-step protein precipitation by acetonitrile was performed to extract the eight analytes from plasma. Our results revealed that all of the calibration curves displayed good linear regression (r2>0.9990). The lower limits of quantification (LLOQ) were determined as 10.0, 9.6, 8.9, 9.1, 9.2, 9.8, 10.1 and 9.8ng/mL. The intra-day and inter-day precisions (RSD) of the eight compounds at high, medium and low levels were less than 4.94% and the bias of the accuracies ranged from -3.89% to 3.95%.The extraction recoveries of the eight compounds were from 90.4% to 100.2% and the matrix effects ranged from 89.3% to 100.1%. The stabilities of these compounds were investigated by analyzing six replicates of QC samples at three different concentrations following storage at 25 degrees C for 4h, -80 degrees C for 30days, three-freeze-thaw cycles, and 4 degrees C for 24h. All the samples showed satisfactory precision and accuracy after various stability tests. Pharmacokinetic parameters were estimated using a non-compartment model. Compared with the crude group, the parameters of Cmax and AUC0-t of 4-caffeoylquinic acid, loganic acid, loganin and asperosaponin VI increased remarkably (p<0.05) after oral administration of the aqueous extract of wine-processed Dipsacus asper, indicating that wine-processing could enhance bioavailability of 4-caffeoylquinic acid, loganic acid, loganin and asperosaponin VI. PMID- 27710889 TI - Measurement of neosaxitoxin in human plasma using liquid-chromatography tandem mass spectrometry: Proof of concept for a pharmacokinetic application. AB - Neosaxitoxin, a member of the saxitoxin family of paralytic shellfish poisoning toxins, has shown potential as an effective, long-acting, anesthetic. We describe the development and validation of a highly sensitive method for measurement of neosaxitoxin in human plasma using liquid chromatography tandem mass spectrometry (LC-MS/MS) and provide evidence for its use in a human pharmacokinetic study. Samples were prepared using cation exchange solid phase extraction followed by hydrophilic interaction liquid chromatography and MS/MS detection in positive electrospray ionization mode. Multiple reaction monitoring was used to monitor neosaxitoxin (m/z 316.17>220.07) and the internal standard analogue decarbamoylneosaxitoxin (m/z 273.12>180.00). The method was validated for lower limit of quantification, precision, accuracy, linearity and matrix effect. The stability of neosaxitoxin in plasma matrix at various storage conditions was also investigated. Standard curves for calibration were linear (r>0.995) across the assay calibration range, 10 to 1000pg/mL. The analytical measurable range of the assay was 10-10,000pg/mL in plasma matrix. This method has demonstrated excellent sensitivity demonstrating a lower limit of quantification in human plasma of 10pg/mL. The mean, inter-batch variation was <5.2% across the concentration range 30 to 800pg/mL. This method was successfully used in a phase 1 trial to investigate the pharmacokinetic profile of neosaxitoxin in humans following the intravenous administration of the drug at a range of doses up to 40MUg. We conclude that our high-sensitivity method for measurement of neosaxitoxin in human plasma is capable of supporting future clinical trials. PMID- 27710890 TI - Development and validation of reverse phase high performance liquid chromatography for citral analysis from essential oils. AB - Citral is a widely used monoterpene aldehyde in aromatherapy, food and pesticide industries. A new validated reverse phase high performance liquid chromatography (RP - HPLC) procedure for the detection and quantification of cis-trans isomers of citral was developed. The RP-HPLC analysis was carried out using Enable C - 18G column (250*4.6mm, 5MU), with acetonitrile and water (70: 30) mobile phase in isocratic mode at 1mL/min flow. A photodiode array (PDA) detector was set at 233nm for the detection of citral. The method showed linearity, selectivity and accuracy for citral in the range of 3-100MUg/mL. In order to compare the new RP HPLC method with the available methods, one of the commercially available essential oil from Cymbopogon flexuosus was analyzed using new RP-HPLC method and the same was analyzed using GC-MS for the comparison of the method for the detection of citral. The GC-MS analysis was done using mass selective detector (MSD) showed citral content to be of 72.76%; wherein the new method showed to contain that same at 74.98%. To prove the application of the new method, essential oils were extracted from lemongrass, lemon leaves and mosambi peels by steam distillation. The citral content present in the essential and also in the condensate was analyzed. The method was found to be suitable for the analysis of citral in essential oils and water based citral formulations with a very good resolution of its components geranial and neral. PMID- 27710891 TI - The study of doping market: How to produce intelligence from Internet forums. AB - Despite the predominant role played by Internet in the distribution of doping substances, little is currently known about the online offer of doping products. Therefore, the study focuses on the detection of doping substances and suppliers discussed in Internet forums. It aims at having a comprehensive understanding of products and sellers to lead an operational monitoring of the online doping market. Thirteen community forums on the Internet were investigated and one million topics were extracted with source code scrappers. Then, a semantic analysis was conducted with a semi-automatic process to classify the relevant words according to doping matters. Additionally, the ranking of doping products, active substances and suppliers in regards to the number of contributors to the forums were established and analyzed over time. Finally, promotion methods of suppliers were evaluated. The results show that anabolic androgenic steroids, used to enhance body image and performance, are the most discussed type of products. A temporal analysis illustrates the stability of the most popular products as well as the emergence of new products such as peptides (e.g. CJC 1295). 327 suppliers were detected, mostly with dedicated websites or direct sales by e-mail as selling methods. Globally, the implemented methodology shows its ability to detect products and suppliers as well as to follow their temporal trends. The intelligence will serve the definition of online monitoring strategies (e.g. the selection of appropriate keywords). Additionally, it also allows the adjustment of customs inspection strategies and anti-doping analysis by monitoring the popular and emerging substances. PMID- 27710892 TI - Solar-driven thermo- and electrochemical degradation of nitrobenzene in wastewater: Adaptation and adoption of solar STEP concept. AB - The STEP concept has successfully been demonstrated for driving chemical reaction by utilization of solar heat and electricity to minimize the fossil energy, meanwhile, maximize the rate of thermo- and electrochemical reactions in thermodynamics and kinetics. This pioneering investigation experimentally exhibit that the STEP concept is adapted and adopted efficiently for degradation of nitrobenzene. By employing the theoretical calculation and thermo-dependent cyclic voltammetry, the degradation potential of nitrobenzene was found to be decreased obviously, at the same time, with greatly lifting the current, while the temperature was increased. Compared with the conventional electrochemical methods, high efficiency and fast degradation rate were markedly displayed due to the co-action of thermo- and electrochemical effects and the switch of the indirect electrochemical oxidation to the direct one for oxidation of nitrobenzene. A clear conclusion on the mechanism of nitrobenzene degradation by the STEP can be schematically proposed and discussed by the combination of thermo and electrochemistry based the analysis of the HPLC, UV-vis and degradation data. This theory and experiment provide a pilot for the treatment of nitrobenzene wastewater with high efficiency, clean operation and low carbon footprint, without any other input of energy and chemicals from solar energy. PMID- 27710893 TI - Pitch perception deficits in nonverbal learning disability. AB - The nonverbal learning disability (NLD) is a neurological dysfunction that affects cognitive functions predominantly related to the right hemisphere such as spatial and abstract reasoning. Previous evidence in healthy adults suggests that acoustic pitch (i.e., the relative difference in frequency between sounds) is, under certain conditions, encoded in specific areas of the right hemisphere that also encode the spatial elevation of external objects (e.g., high vs. low position). Taking this evidence into account, we explored the perception of pitch in preadolescents and adolescents with NLD and in a group of healthy participants matched by age, gender, musical knowledge and handedness. Participants performed four speeded tests: a stimulus detection test and three perceptual categorization tests based on colour, spatial position and pitch. Results revealed that both groups were equally fast at detecting visual targets and categorizing visual stimuli according to their colour. In contrast, the NLD group showed slower responses than the control group when categorizing space (direction of a visual object) and pitch (direction of a change in sound frequency). This pattern of results suggests the presence of a subtle deficit at judging pitch in NLD along with the traditionally-described difficulties in spatial processing. PMID- 27710894 TI - Ginger extract protects rat's kidneys against oxidative damage after chronic ethanol administration. AB - Chronic alcohol ingestion is associated with pronounced detrimental effects on the renal system. In the current study, the protective effect of ginger extract on ethanol-induced damage was evaluated through determining 8-OHdG, cystatin C, glomerular filtration rate, and pathological changes such as cell proliferation and fibrosis in rats' kidneys. Male wistar rats were randomly divided into three groups and were treated as follows: (1) control, (2) ethanol and (3) ginger extract treated ethanolic (GETE) groups. After a six weeks period of treatment, the results revealed proliferation of glomerular and tubular cells, fibrosis in glomerular and peritubular and a significant rise in the level of 8-OHdG, cystatin C, plasma urea and creatinine. Moreover, compared to the control group, the ethanol group showed a significant decrease in the urine creatinine and creatinine clearance. In addition, significant amelioration of changes in the structure of kidneys, along with restoration of the biochemical alterations were found in the ginger extract treated ethanolic group, compared to the ethanol group. These findings indicate that ethanol induces kidneys abnormality by oxidative DNA damage and oxidative stress, and that these effects can be alleviated using ginger as an antioxidant and anti-inflammatory agent. PMID- 27710895 TI - CD200Fc attenuates inflammatory responses and maintains barrier function by suppressing NF-kappaB pathway in cigarette smoke extract induced endothelial cells. AB - BACKGROUND: Recent evidence suggests that CD200 fusion protein (CD200Fc), a CD200R1 agonist may attenuate inflammatory responses in autoimmune diseases and neuro-degeneration. While, little is known about the function of CD200Fc in cigarette smoke extract (CSE)-induced mouse Cardiac Microvascular Endothelial Cells (mCMECs). The present study was designed to elucidate the effects of CD200Fc on CSE-induced vascular endothelial barrier (VEB) dysfunction and inflammatory responses, which is a highly clinically relevant model of smoking related cardiovascular diseases. METHODS: mCMECs were pre-treated with 1, 10 and 100MUg/ml CD200Fc for 24h respectively, and then treated with 250MUg/ml CSE for different times (24h or 120min). The transepithelial electrical resistance (TEER) and transport of fluorescent markers were used to measure VEB function in CSE induced mCMECs. Western blot and immunofluorescent staining analysis were used to detect the expression of tight junction proteins, such as Zona Occludens-1 (ZO-1) and Claudin-1 in CSE-induced mCMECs. We measured the expression of pro inflammatory cytokines in CSE-induced mCMECs by using ELISA and RT-PCR. In addition, the NF-kappaB activity in CSE-induced mCMECs were investigated by using nuclear/cytosol fractionation and western blot analysis. RESULTS: In vitro treatment with CSE increased the transport of fluorescent markers and decreased TEER levels in mCMECs, respectively, which were attenuated by CD200Fc (10 and 100MUg/ml) pretreatment. The CSE-induced up-regulation of pro-inflammatory cytokines such as Cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), platelet endothelial cell adhesion molecule-1 (PECAM-1), vascular cell adhesion molecule-1 (ICAM-1), Prostaglandin E2 (PGE2), tumor necrosis factor alpha (TNF-alpha), interleukin-6 (IL-6) and IL-8 in mCMECs was also abrogated by CD200Fc (10 and 100MUg/ml) pretreatment. CD200Fc also inhibited CSE-induced nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) activation in mCMECs, such as inhibition of its DNA binding activity, phosphorylated expression, and translocation to nucleus. CONCLUSION: Thus, CD200Fc exert anti-inflammatory effect and protect VEB function in CSE-induced mCMECs. The vasoprotective effects of CD200Fc may be specifically beneficial in pathophysiological conditions associated with smoking related cardiovascular diseases. PMID- 27710896 TI - miRNA-133b and miRNA-135a induce apoptosis via the JAK2/STAT3 signaling pathway in human renal carcinoma cells. AB - Aberrantly expressed microRNAs (miRNAs) are involved in many diseases including cancer. In clear cell renal cell carcinoma (ccRCCs) expression of miR-133b and miR-135a is reduced compared to control tissue and other sarcomas but the functional effects of this downregulation are not fully understood. This study aimed at evaluating the miR-133b and miR-135a expression profiles in different RCC subtypes and the functional role of these miRNAs. Viability and apoptosis were examined in three different ccRCC cell lines (786-O, A498 and SN12-PM6) after over-expression of these miRNAs. The modulation of JAK2 and the JAK2/STAT3 pathways was determined by Western blot. Transient transfection of miR-133b and miR-135a reduced viability and induced apoptosis by inhibition of JAK2 expression and its phosphorylation and activation of caspase 3 and 7 in all three ccRCC cell lines. p-STAT3 and Bcl-2 expression was reduced after miRNA transfection whereas only slight influence on Bcl-2 L11 (BIM) was detected. Our results demonstrate that miR-133b and miR-135a which are down-regulated in wildtype and mutated ccRCCs, induce apoptosis in vitro by a signaling cascade involving JAK2, STAT3 and Bcl-2. Therefore, over-expression of these miRNAs seems to functionally counteract oncogenic signalling pathways in ccRCCs. PMID- 27710897 TI - BZ-26, a novel GW9662 derivate, attenuated inflammation by inhibiting the differentiation and activation of inflammatory macrophages. AB - Peroxisome proliferator-activated receptor-gamma (PPARgamma) is considered to be an important transcriptional factor in regulation of macrophages differentiation and activation. We have synthesized a series of novel structural molecules based on GW9662's structure (named BZ-24, BZ-25 and BZ-26), and interaction activity was calculated by computational docking. BZ-26 had shown stronger interaction with PPARgamma and had higher transcriptional inhibitory activity of PPARgamma with lower dosage compared with GW9662. BZ-26 was proved to inhibit inflammatory macrophage differentiation. LPS-induced acute inflammation mouse model was applied to demonstrate its anti-inflammatory activity. And the results showed that BZ-26 administration attenuated plasma tumor necrosis factor-alpha (TNF alpha) and interleukin-6 (IL-6) secretion, which are vital cytokines in acute inflammation. The anti-inflammatory activity was examined in THP-1 cell line, and TNF-alpha, IL-6 and MCP-1, were significantly inhibited. The results of Western blot and luciferase reporter assay indicated that BZ-26 not only inhibited NF kappaB transcriptional activity, but also abolished LPS-induce nuclear translocation of P65. We also test BZ-26 action in tumor-bearing chronic inflammation mouse model, and BZ-26 was able to alter macrophages phenotype, resulting in antitumor effect. All our data revealed that BZ-26 modulated LPS induced acute inflammation via inhibiting inflammatory macrophages differentiation and activation, potentially via inhibition of NF-kappaB signal pathway. PMID- 27710899 TI - Proliferation-enhancing effects of gastrodin on RSC96 Schwann cells by regulating ERK1/2 and PI3K signaling pathways. AB - The proliferation and migration of Schwann cells (SCs) are essential in the process of peripheral nerve repair. A large amount of studies focused on the promotion of the growth of SCs for cell based therapy. Gastrodin (GAS), the main constituent of a Chinese traditional herbal medicine named Gastrodia elata Blume, has been reported to be associated with neuroprotective properties. Besides, GAS activated MAPK and PI3K signaling pathways which are often involved in growth of nerve cells were also reported. Based on the hypothesis that GAS may have an effect on SCs growth, we studied the effect of GAS on rat RSC96 Schwann cells (SCs) and further explored the underlying mechanism. Various concentration of GAS (0MUM, 50MUM, 100MUM, and 200MUM) was used for treatment of RSC96 SCs, with the cell proliferation and gene expression of several neurotrophic factors to be detected. Regulation of MAPK and PI3K signaling pathways were assayed by detecting phosphorylation of ERK1/2 and Akt. The results showed that GAS could effectively promote proliferation of RSC96 SCs in a dose- and time-dependent manner. The best performance was obtained at the concentration of 200MUM. Exploration of the underlying mechanism showed that GAS probably affects SCs metabolism through inhibiting ERK1/2 phosphorylation and activating Akt phosphorylation in RSC96 SCs. This study may provide reference for its application in treatment of peripheral nerve injuries. PMID- 27710898 TI - Nephro-protective action of P. santalinus against alcohol-induced biochemical alterations and oxidative damage in rats. AB - The present study investigated the antioxidant potential of P. santalinus heartwood methanolic extract (PSE) against alcohol-induced nephro-toxicity. The results indicated an increase in the concentration of kidney damage plasma markers, urea and creatinine with a concomitant decrease in the concentration of uric acid in alcohol-administered rats. A significant decrease in plasma electrolytes and mineral levels with increased kidney thiobarbituric acid reactive substances (TBARS) and nitric oxide (NOx) levels was also observed. PSE treatment to alcohol-administered rats effectively prevented the elevation in TBARS and NOx levels. Decreased activity of Na+/K+-ATPase in alcohol administered rats was brought to near normal levels with treatment of PSE. Chronic alcohol consumption affects antioxidant enzymatic activity and reabsorption function of the kidney which is evident from the decreased level of GSH as well as the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR) and glutathione s-transferase (GST). However, treatment with PSE to alcohol-administered rats significantly enhanced these enzymatic activities and reduced glutathione (GSH) content close to normal level. Alcohol-induced organ damage was evident from morphological changes in the kidney. Nevertheless, administration of PSE effectively restored these morphological changes to normal. The flavonoid and tannoid compounds might have protective activity against alcohol-induced oxidative/nitrosative stress mediated kidney damage.

AB - Misfolded beta-sheet-rich protein aggregates termed amyloid, deposit in vivo leading to debilitating diseases such as Alzheimer's, prion and renal amyloidosis diseases etc. Strikingly, amyloid can induce conversion of their natively folded monomers into similarly aggregated conformation via 'seeding'. The specificity of seeding is well documented in vivo for prions, where prion-variants arising from conformationally altered amyloids of the same protein, faithfully seed monomers into amyloid displaying the original variant's conformation. Thus far, amyloid variant formation is reported only for a few non-prion proteins like Alzheimer's Abeta42-peptide and beta-2 microglobulin, however, their conformational cross seeding capabilities are unexplored. While mutant human lysozyme causes renal amyloidosis, the hen egg white lysozyme (HEWL) has been extensively investigated in vitro as a model amyloid protein. Here we investigated if wild-type HEWL could form self-seeding amyloid variants to examine if variant formation is more wide spread. We found that HEWL aggregates formed under quiescent versus agitated conditions, displayed different particle sizes, detergent stabilities & beta sheet content, and they only seeded monomeric HEWL under similar incubation conditions, but not under swapped incubation conditions thereby showing amyloid variant formation by HEWL analogous to prion variants. This may have implications to the amyloidosis caused by different mutants of human lysozyme.

AB - trans-BMPyP induced the B-Z transition for alternated AT oligonucleotides as it was evident by inversed CD spectrum.

Insertion of one or two GC base pairs prevented the B-Z transition. PMID- 27710902 TI - Childhood trauma and HPA axis functionality in offspring of bipolar parents. AB - Children of a parent with bipolar disorder (bipolar offspring) have an increased risk for mood disorders. While genetic factors play a significant role in this population, susceptibility to environmental stress may also significantly contribute to this vulnerability for mood disorders. Childhood trauma has consistently been found to increase the risk for mood disorders, with persisting consequences for hypothalamic-pituitary-adrenal (HPA) axis functionality. However, it is currently unknown whether childhood trauma specifically affects HPA axis activity in individuals with a familial risk for bipolar disorder. Therefore, we investigated the effects of childhood trauma on daytime and evening cortisol levels and dexamethasone suppression in bipolar offspring (N=70) and healthy controls (N=44). In our study we found no significant differences in daytime and evening cortisol levels as well as dexamethasone suppression between bipolar offspring and healthy controls (all p-values>0.43). In contrast, childhood trauma differentially affected daytime cortisol levels in the bipolar offspring compared to healthy controls (childhood trauma X bipolar offspring interaction, beta=-7.310, p=0.0414) with an effect of childhood trauma on daytime cortisol in bipolar offspring at trend level (p=0.058). In the bipolar offspring group, lifetime or current psychiatric diagnoses, and stressful life events separately did not affect cortisol levels or dexamethasone suppression (all p values>p=0.50). These findings were independent of current or lifetime psychiatric diagnosis. In conclusion, trauma-related changes in daytime HPA axis activity appear to be a specific trait in bipolar offspring who have increased risk for mood disorders compared to healthy individuals. PMID- 27710903 TI - How China achieved its 11th Five-Year Plan emissions reduction target: A structural decomposition analysis of industrial SO2 and chemical oxygen demand. AB - To curb the increasing pollutant emissions that have accompanied rapid economic growth, China implemented a mandatory emissions control system since the 11th Five-Year Plan (FYP) period, and the emission reduction targets have been met and even exceeded. This article explores how China achieved its emissions reduction targets by systematically identifying the main emission reduction pathways, including both the environmental and economic factors, and evaluates the contribution of each factor using structure decomposition analysis. A study of the two key controlled pollutants, industrial sulfur dioxide (SO2) and chemical oxygen demand (COD), during the 11th FYP period showed that (i) changes in the end-of-pipe treatment and pollutant generation coefficient were the dominant contributors to emissions reduction. The power and metal smelting sectors played important roles in SO2 abatement, while the paper products and food products sectors were important in COD reduction; (ii) changes to the input coefficient increased overall emissions although there was a decrease in SO2 emissions in 2007-2010 mainly due to input structure improvements in the construction sector; (iii) the trade effect largely offset the domestic emission reduction effects, although the trade effect declined during the study period; (iv) domestic demand was the main factor increasing domestic emissions; domestic investment changes (especially in the construction sector) were the major contributor to increases in SO2 emissions, and final consumption changes (especially consumption in the food production sector) were the main contributor to the increase in COD emissions. The results yield important implications for China's pollution emissions control policies. PMID- 27710904 TI - Polychlorinated biphenyl exposure and deiodinase activity in young infants. AB - BACKGROUND: Several studies have shown effects of polychlorinated biphenyls (PCBs) on serum thyroid hormone levels in pregnant woman and their infants, while other studies did not find such effects. How PCBs might affect thyroid hormone metabolism, is still unclear. Potential mechanisms are direct influence on the thyroid gland, binding to thyroid binding proteins, increased excretion or metabolism of thyroid hormones by deiodinases or sulfatases. It is also not well known whether the effect on thyroid hormone levels is caused by PCBs themselves, or by their hydroxylated metabolites (OH-PCBs). OBJECTIVE: To determine the effects of perinatal exposure to PCBs and OH-PCBs on thyroid hormone levels in cord blood and in serum of newborn infants. METHODS: In a Dutch cohort of 100 mother-infant pairs, exposed to background PCB levels, correlations were assessed between 10 PCBs and 6 OH-PCBs in maternal blood during pregnancy and serum thyroxine (T4), T4 sulfate (T4S), triiodothyronine (T3), reverse T3 (rT3), thyroid-stimulating hormone (TSH) and thyroxine-binding globulin (TBG) levels in cord blood and in serum of three- and 18-month-old infants. We corrected for age of the mother, gestational age, gender and type of feeding. RESULTS: After correction, prenatal levels of three of 10 measured PCBs showed a positive correlation with cord serum T3, and four PCBs showed a negative correlation with cord serum rT3. After correction, two PCBs and the sum of the 10 measured PCBs were positively correlated with the cord serum T3/rT3 ratio, an indicator of deiodinase 3 activity. No correlations were found between PCBs and T4, TSH and TBG in cord blood. 4-OH-PCB-107 was correlated with T4 at 3months and T4, T4S and T3 at 18months. CONCLUSION: Our results suggest that PCBs have a negative effect on deiodinase type 3 activity, as reflected by a positive correlation with the T3/rT3 ratio. We identified a potential mechanism by which PCBs may affect thyroid hormone metabolism during human development. PMID- 27710905 TI - Towards understanding the integrative approach of the water, energy and food nexus. AB - The water, energy and food nexus (WEF nexus) is currently quite popular in environmental management. The concept found a fertile ground in science and policymaking, but there is no consistent view on the meaning of integration within the nexus. Here, a wealth of publications is reviewed in an endeavour to: (1) reveal the lines of justification for the need of the WEF nexus debate and (2) identify the range of tools for analysing the interdependent resource issues of the nexus using an integrated framework of science and policy. There are three drivers behind the emergence of the nexus thinking. These are a) increasing resource interlinks due to growing scarcities, b) recent resource supply crises, and c) failures of sector-driven management strategies. Evaluation of the WEF nexus integrative debate can be carried out using four key criteria, namely ability to change current policy debates, issue and thinking novelty, practicability and measurability, and clearness and implementation roadmap. It is clear that, although the nexus has been quite successful in changing policy debates, issue prioritization is missing and seems to be left to specific case studies and policymakers' choices. There is a high need for 'incorporation' and 'cross-linking' of issues between the three resources. In this regard, nexus governance is the missing link in the nexus debate. PMID- 27710907 TI - Modeling the dynamic volatile fatty acids profiles with pH and hydraulic retention time in an anaerobic baffled reactor during the startup period. AB - To predict the dynamic profiles in volatile fatty acids (VFAs) with pH and hydraulic retention time (HRT) during the startup of a 4-compartment ABR, a mathematical model was constructed by introducing pH and thermodynamic inhibition functions into the biochemical processes derived from the ADM1. The calibration of inhibition parameter for propionate uptake effectively improved the prediction accuracy of VFAs. The developed model could simulate the VFAs profiles very well no matter the observable change of pH or/and HRT. The simulation results indicated that both H2-producing acetogenesis and methanogenesis in the ABR would be inhibited with a pH less than 4.61, and the propionate oxidation could be thermodynamically restricted even with a neutral pH. A decreased HRT would enhanced the acidogenesis and H2-producing acetogenesis in the first 3 compartments, but no observable increase in effluent VFAs could be found due to the synchronously enhanced methanogenesis in the last compartment. PMID- 27710906 TI - Explosive genetic evidence for explosive human population growth. AB - The advent of next-generation sequencing technology has allowed the collection of vast amounts of genetic variation data. A recurring discovery from studying larger and larger samples of individuals had been the extreme, previously unexpected, excess of very rare genetic variants, which has been shown to be mostly due to the recent explosive growth of human populations. Here, we review recent literature that inferred recent changes in population size in different human populations and with different methodologies, with many pointing to recent explosive growth, especially in European populations for which more data has been available. We also review the state-of-the-art methods and software for the inference of historical population size changes that lead to these discoveries. Finally, we discuss the implications of recent population growth on personalized genomics, on purifying selection in the non-equilibrium state it entails and, as a consequence, on the genetic architecture underlying complex disease and the performance of mapping methods in discovering rare variants that contribute to complex disease risk. PMID- 27710908 TI - Stimulation of waste decomposition in an old landfill by air injection. AB - Three pilot-scale lysimeters were operated for 4.5years to quantify the change in the carbon and nitrogen pool in an old landfill under various air injection conditions. The results indicate that air injection at the bottom layer facilitated homogeneous distribution of oxygen in the waste matrix. Substantial total organic carbon (TOC) decomposition and methane generation reduction were achieved. Considerable amount of nitrogen was removed, suggesting that in situ nitrogen removal via the effective simultaneous nitrification and denitrification mechanism is viable. Moreover, material mass change measurements revealed a slight mass reduction of aged MSW (by approximately 4.0%) after 4.5years of aeration. Additionally, experiments revealed that intensive aeration during the final stage of the experiment did not further stimulate the degradation of the aged MSW. Therefore, elimination of the labile fraction of aged MSW should be considered the objective of in situ aeration. PMID- 27710909 TI - Microbial conversion of mixed volatile fatty acids into microbial lipids by sequencing batch culture strategy. AB - Four mixed volatile fatty acids (VFAs) were used as sole carbon source to culture oleaginous yeast Cryptococcus curvatus by sequencing batch culture strategy. The highest lipid content (42.7%) and concentration (1.77g/L) were achieved when the ratio of VFAs (acetic, propionic, and butyric acids) was 6:3:1. The oleaginous yeast favored to use VFAs for lipid biosynthesis rather than cell proliferation. With regard to the utilization ratio of VFAs, acetic acid reached over 99%, whereas propionic acid was barely 35%. The produced lipids contained nearly 45% of monounsaturated fatty acids, which can be the ideal raw materials for biodiesel production. Additionally, the produced odd-numbered fatty acid content reached 23.6% when the propionate acid content of VFAs was 50%. Further analysis showed that increasing the ratio of acetic acid was most beneficial to cell mass and lipid production, whereas propionic acid and butyric acid were more conducive to lipid and cell mass synthesis, respectively. PMID- 27710910 TI - Pretreatment of food waste with high voltage pulse discharge towards methane production enhancement. AB - Anaerobic batch tests were performed to investigate the methane production enhancement and solid transformation rates from food waste (FW) by high voltage pulse discharge (HVPD) pretreatment. The total cumulative methane production with HVPD pretreatment was 134% higher than that of the control. The final volatile solids transformation rates of FW with and without HVPD pretreatment were 54.3% and 32.3%, respectively. Comparison study on HVPD pretreatment with acid, alkali and ultrasonic pretreatments showed that the methane production and COD removal rates of FW pretreated with HVPD were more than 100% higher than the control, but only about 50% higher can be obtained with other pretreatments. HVPD pretreatment could be a promising pretreatment method in the application of energy recovery from FW. PMID- 27710911 TI - Mechanistic insight from murine models of Netherton syndrome. AB - Protease regulation plays a crucial role in skin homeostasis and inflammation as revealed by the identification of loss-of-function mutations in SPINK5 (serine protease inhibitor of Kazal type 5) in Netherton sydrome (NS). SPINK5 encodes LEKTI (lympho-epithelial Kazal type related inhibitor), a multidomain serine protease inhibitor expressed in all stratified epithelia. Our laboratory has developed a number of murine models which have been instrumental in dissecting the pathogenesis of NS. This minireview discusses the major findings of these models and emphasizes the role of protease regulation, especially kallikrein related peptidases in NS.

AB - While being well known that the diagnosis of many genetic disorders relies on a combination of clinical suspicion and confirmatory genetic testing, not rarely, however, genetic testing needs much perseverance and cunning strategies to identify the causative mutation(s). Here we present a case of a thorny molecular diagnosis of mucolipidosis type III alpha/beta, which is an autosomal recessive lysosomal storage disorder, caused by a defect in the GNPTAB gene that codes for the alpha/beta-subunits of the GlcNAc-1-phosphotransferase. We used both cDNA and gDNA analyses to characterize a mucolipidosis type III alpha/beta patient whose clinical diagnosis was already confirmed biochemically. In a first stage only one causal mutation was identified in heterozygosity, the already described missense mutation c.1196C>T(p.S399F), both at cDNA and gDNA levels. Only after conducting inhibition of nonsense-mediated mRNA decay (NMD) assays and after the utilization of another pair of primers the second mutation, the c.3503_3504delTC deletion, was identified. Our findings illustrate that allelic dropout due to the presence of polymorphisms and/or of mutations that trigger the NMD pathway can cause difficulties in current molecular diagnosis tests. PMID- 27710914 TI - Increased oxidative stress parameters in children with moderate iodine deficiency. AB - BACKGROUND: Iodine is a part of thyroid hormones and has been reported to act directly as an antioxidant or induce indirectly antioxidant enzymes. This study aimed to assess the urinary iodine concentration and its relationship between the antioxidant and oxidative stress capacity in healthy school-aged children. METHODS: In total, 196 students from five primary schools, randomly selected between 9 and 12 years (mean age: 10.2+/-1.2 years), were enrolled in the study. Urinary iodine levels were measured by spectrophotometry with the Sandell Kolthoff reaction. Total antioxidant status (TAS) and total oxidant status (TOS) were analysed from urine samples. The ratio of TOS to TAS was regarded as an oxidative stress index (OSI), an indicator of the degree of oxidative status. RESULTS: Fifty-four percentage (107) of the children had iodine deficiency (ID) and the majority of them (30%) had mild ID. There was no severe-ID child in the population (<20 MUg/L). Urine TAS levels were significantly lower in the moderate ID group than in the mild-ID group (6.5+/-4.1 vs. 11.3+/-4.1 mmol, p<0.001) and the iodine-sufficient group (11.0+/-5.3 MUmol, p<0.001). TOS levels and OSI were found higher in the moderate-ID group than in the mild-ID group (4.8+/-2.1 vs. 3.7+/-2.1 MUmol, p<0.001) and the iodine-sufficient group (4.8+/-2.1 vs. 3.4+/ 2.5 mmol, p<0.001). In the moderate-ID group, low urine iodine levels exhibited significant negative correlations with OSI (r=-0.660) and TOS (r=-0.248) and a positive correlation with TAS (r=0.475). CONCLUSIONS: We found that children with moderate ID were exposed to more oxidative burden than children with mild ID or iodine sufficiency. Increased systemic oxidative stress induced by moderate ID could cause development of ID-related complications and diseases. Iodine supplementation could have a beneficial role in the prevention of oxidative stress. PMID- 27710915 TI - Lipoprotein-associated phospholipase A2 activity and low-density lipoprotein subfractions after a 2-year treatment with atorvastatin in adolescents with type 1 diabetes. AB - BACKGROUND: The objective of the study was to assess the effect of atorvastatin on inflammation markers and low-density lipoprotein (LDL) subfractions. METHODS: In a prospective, randomized, double-blind pilot study involving 28 adolescents with type 1 diabetes (T1D), lipoprotein-associated phospholipase A2 (Lp-PLA2) activity, high-sensitivity C-reactive protein (hsCRP), and subfractions of LDL were measured at baseline, after 1 year and 2 years of treatment with atorvastatin (10 mg/day) vs. placebo. RESULTS: For the atorvastatin group, we found posttreatment reductions of Lp-PLA2 activity (p<0.001), LDL cholesterol (p=0.001), non-small dense LDL cholesterol (p<0.001), total cholesterol (p<0.001), and apolipoprotein B (apo B) (p<0.001), whereas small dense LDL cholesterol and hsCRP did not change significantly. CONCLUSIONS: In adolescents with T1D, long-term treatment with atorvastatin is safe and may reduce cardiovascular risk by significant decreases of Lp-PLA2 activity and LDL cholesterol. PMID- 27710916 TI - Pituitary volume in children with growth hormone deficiency, idiopathic short stature and controls. AB - BACKGROUND: The objective of the study was to describe the pituitary volume (PV) in pediatric patients with isolated growth hormone deficiency (IGHD), idiopathic short stature (ISS) and normal controls. METHODS: Sixty-nine patients (57 male, 12 female), with a mean age of 11.9 (+/-2.0), were determined to have IGHD. ISS was identified in 29 patients (20 male, 9 female), with a mean age of 12.7 (+/ 3.7). Sixty-six controls (28 female, 38 male), mean age 9.8 (+/-4.7) were also included. Three-dimensional (3D) magnetic resonance images with contrast were obtained to accurately measure PV. RESULTS: There was a significant difference in the mean PV among the three groups. The IGHD patients had a mean PV 230.8 (+/ 89.6), for ISS patients it was 286.8 (+/-108.2) and for controls it was 343.7 (+/ 145.9) (p<0.001). There was a normal increase in PV with age in the ISS patients and controls, but a minimal increase in the IGHD patients. CONCLUSIONS: Those patients with isolated GHD have the greatest reduction in PV compared to controls and the patients with ISS fall in between. We speculate that a possible cause for the slowed growth in some ISS patients might be related to diminished chronic secretion of growth hormone over time, albeit having adequate pituitary reserves to respond acutely to GH stimulation. Thus, what was called neurosecretory GHD in the past, might, in some patients, be relative pituitary hypoplasia and resultant diminished growth hormone secretion. Thus, PV determinations by magnetic resonance imaging (MRI) could assist in the diagnostic evaluation of the slowly growing child. PMID- 27710917 TI - Primary hyperparathyroidism may masquerade as rickets-osteomalacia in vitamin D replete children. AB - Primary hyperparathyroidism, typically a disease of the middle aged and the old, is less commonly seen in children. In children the disease has a bimodal age distribution with calcium sensing receptor mutation presenting in infancy as hypercalcemic crises and parathyroid adenoma or hyperplasia presenting later in childhood with bone disease. The childhood parathyroid adenomas are often familial with multiglandular disease and manifest with severe bone disease unlike adults. We report a series of four male patients with juvenile primary hyperparathyroidism, three of whom presented with bone disease masquerading as rickets-osteomalacia. One patient had asymptomatic hypercalcemia with short stature. Parathyroid adenoma was detected in all the four cases and all of them underwent resection of parathyroid adenomas confirmed on histopathology. Post surgery all the cases had initial hypocalcaemia followed by normocalcemia. One case developed pancreatitis after surgery even after achieving normocalcemia. We conclude that parathyroid adenomas, although uncommon in children, are an important cause of skeletal disease that may initially be confused with hypovitaminosis D. PMID- 27710918 TI - Editorial. PMID- 27710919 TI - Prospects for Higgs physics at energies up to 100 TeV. AB - We summarize the prospects for Higgs boson physics at future proton-proton colliders with centre of mass (c.m.) energies up to 100 TeV. We first provide the production cross sections for the Higgs boson of the Standard Model from 13 TeV to 100 TeV, in the main production mechanisms and in subleading but important ones such as double Higgs production, triple production and associated production with two gauge bosons or with a single top quark. We then discuss the production of Higgs particles in beyond the Standard Model scenarios, starting with the one in the continuum of a pair of scalar, fermionic and vector dark matter particles in Higgs-portal models in various channels with virtual Higgs exchange. The cross sections for the production of the heavier CP-even and CP-odd neutral Higgs states and the charged Higgs states in two-Higgs doublet models, with a specific study of the case of the Minimal Supersymmetric Standard Model, are then given. The sensitivity of a 100 TeV proton machine to probe the new Higgs states is discussed and compared to that of the LHC with a c.m. energy of 14 TeV and at high luminosity.

PMID- 27710921 TI - Frequency-based nanoparticle sensing over large field ranges using the ferromagnetic resonances of a magnetic nanodisc. AB - Using finite element micromagnetic simulations, we study how resonant magnetisation dynamics in thin magnetic discs with perpendicular anisotropy are influenced by magnetostatic coupling to a magnetic nanoparticle. We identify resonant modes within the disc using direct magnetic eigenmode calculations and study how their frequencies and spatial profiles are changed by the nanoparticle's stray magnetic field. We demonstrate that particles can generate shifts in the resonant frequency of the disc's fundamental mode which exceed resonance linewidths in recently studied spin torque oscillator devices. Importantly, it is shown that the simulated shifts can be maintained over large field ranges (here up to 1 T). This is because the resonant dynamics (the basis of nanoparticle detection here) respond directly to the nanoparticle stray field, i.e. detection does not rely on nanoparticle-induced changes to the magnetic ground state of the disc. A consequence of this is that in the case of small disc particle separations, sensitivities to the particle are highly mode- and particle position-dependent, with frequency shifts being maximised when the intense stray field localised directly beneath the particle can act on a large proportion of the disc's spins that are undergoing high amplitude precession. PMID- 27710922 TI - Hyaluronic acid-based hydrogel scaffold without angiogenic growth factors enhances ovarian tissue function after autotransplantation in rats. AB - One of the problems encountered during ovarian transplantation is that the number of primordial follicles in the grafts is considerably reduced 2 d after transplantation due to post-transplantation ischemia. This study investigates if the use of hyaluronic acid-based hydrogel (HABH) with and without vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) could prevent or minimize ischemia-induced follicle loss during ovarian autotransplantation and thereby restore ovarian tissue function in the rat model. In this study, twenty four female rats were subjected to bilateral ovariectomy and were randomly divided into 3 groups for ovarian tissue autotransplantation. Group A included rats with ovarian tissue without HABH, VEGF and bFGF, group B comprised rats with ovarian tissue encapsulated with HABH and group C had rats with ovarian tissue encapsulated with HABH containing VEGF and bFGF. Three days after transplantation, the grafts were assessed through histological and hormonal analyses. Apoptotic, angiogenic and maturation genes expressions were also analyzed. The mean number of follicles in all developmental stages increased in group B (P < 0.05). The level of FSH decreased in group B (P < 0.05) whereas, the expression level of VEGF gene increased in group B (P < 0.05). No significant changes were observed in the expression levels of maturation and apoptotic genes in all groups. In conclusion, ovarian encapsulation with HABH alone can prevent or minimize ischemia-induced follicle loss, preserve the follicular pool, promote follicular survival, facilitate angiogenesis, and restore hormone levels. However, its efficiency in a clinical setting and in comparison with other hydrogels needs further investigation. PMID- 27710923 TI - In vitro characterization of electrochemically compacted collagen matrices for corneal applications. AB - Loss of vision due to corneal disease is a significant problem worldwide. Transplantation of donor corneas is a viable treatment option but limitations such as short supply and immune-related complications call for alternative options for the treatment of corneal disease. A tissue engineering-based approach using a collagen scaffold is a promising alternative to develop a bioengineered cornea that mimics the functionality of native cornea. In this study, an electrochemical compaction method was employed to synthesize highly dense and transparent collagen matrices. We hypothesized that chemical crosslinking of electrochemically compacted collagen (ECC) matrices will maintain transparency, improve stability, and enhance the mechanical properties of the matrices to the level of native cornea. Further, we hypothesized that keratocyte cell viability and proliferation will be maintained on crosslinked ECC matrices. The results indicated that uncrosslinked and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide-N hydroxysuccinimide (EDC-NHS) crosslinked ECC matrices were highly transparent with light transmission measurements comparable to native cornea. Stability tests showed that while the uncrosslinked ECC matrices degraded within 6 h when treated with collagenase, EDC-NHS or genipin crosslinking significantly improved the stability of ECC matrices (192 h for EDC-NHS and 256 h for genipin). Results from the mechanical tests showed that both EDC-NHS and genipin crosslinking significantly improved the strength and modulus of ECC matrices. Cell culture studies showed that keratocyte cell viability and proliferation are maintained on EDC-NHS crosslinked ECC matrices. Overall, results from this study suggest that ECC matrices have the potential to be developed as a functional biomaterial for corneal repair and regeneration. PMID- 27710924 TI - Gruneisen parameter studies on heavy fermion quantum criticality. AB - The Gruneisen parameter, experimentally determined from the ratio of thermal expansion to specific heat, quantifies the pressure dependence of characteristic energy scales of matter. It is highly enhanced for Kondo lattice systems, whose properties are strongly dependent on the pressure sensitive antiferromagnetic exchange interaction between f- and conduction electrons. In this review, we focus on the divergence of the Gruneisen parameter and its magnetic analogue, the adiabatic magnetocaloric effect, for heavy-fermion metals near quantum critical points. We compare experimental results with current theoretical models, including the effect of strong geometrical frustration. We also discuss the possibility of using materials with the divergent magnetic Gruneisen parameter for adiabatic demagnetization cooling to very low temperatures. PMID- 27710925 TI - Curcumin eluting nanofibers augment osteogenesis toward phytochemical based bone tissue engineering. AB - Curcumin is a phenolic compound isolated from Curcuma longa that is known to exhibit wide ranging biological activity including potential benefits for bone growth. The aim of this work was to engineer curcumin eluting tissue scaffolds and investigate their potential use in bone tissue regeneration. We prepared curcumin loaded poly(epsilon-caprolactone) (PCL) nanofibers by electrospinning. Morphological characterization of the nanofibers revealed that the average diameter of neat fibers and that of fibers with 1 wt% and 5 wt% curcumin is 840 +/- 130 nm, 827 +/- 129 nm and 680 +/- 110 nm, respectively. Fourier transformation infrared spectroscopy and 1H nuclear magnetic resonance confirmed the successful loading of the drug in fibers. In aqueous medium, the fibers released ~18% of the encapsulated drug in 3 d and ~60% in 9 d. The cell response to the curcumin loaded nanofibers was assessed using MC3T3-E1 pre osteoblasts. Cell proliferation was moderated with increased loading of curcumin and was 50% lower on the fibers containing 5% curcumin at day 10 than the control fibers. Osteogenesis was confirmed by assaying the expression of alkaline phosphatase and staining of mineral deposits by Alizarin red stain, which were both markedly higher for 1% curcumin compared to neat polymer but lower for 5% curcumin. Mineral deposition was also confirmed chemically by Fourier transform infrared spectroscopy. These results were corroborated by increased gene and protein expression of known osteogenic markers in 1% curcumin. Thus, controlled release of curcumin from polymer scaffolds is a promising strategy for bone tissue regeneration.

AB - So far, actuated fish models have been used to study animal interactions in small scale controlled experiments. This study, conducted in a semi-controlled setting, investigates robot5 interactions with a large wild-caught marine fish school (~3000 individuals) in their natural social environment. Two towed fish robots were used to decouple size, tail motion and speed in a series of sea-cage experiments. Using high-resolution imaging sonar and sonar-video blind scoring, we monitored and classified the school's collective reaction towards the fish robots as attraction or avoidance. We found that two key releasers-the size and the speed of the robotic fish-were responsible for triggering either evasive reactions or following responses. At the same time, we found fish reactions to the tail motion to be insignificant. The fish evaded a fast-moving robot even if it was small. However, mackerels following propensity was greater towards a slow small robot. When moving slowly, the larger robot triggered significantly more avoidance responses than a small robot. Our results suggest that the collective responses of a large school exposed to a robotic fish could be manipulated by tuning two principal releasers-size and speed. These results can help to design experimental methods for in situ observations of wild fish schools or to develop underwater robots for guiding and interacting with free-ranging aggregated aquatic organisms.

AB - Polyhydroxyalkanoate (PHA) is a microbial polymer that has been at the forefront of many attempts at tissue engineering. However, the surface of poly(3 hydroxybutyrate-co-4-hydroxybutyrate) (P(3HB-co-4HB)) is hydrophobic with few recognition sites for cell attachment. Various concentrations of fish-scale collagen peptides (FSCPs) were incorporated into P(3HB-co-4HB) copolymer by aminolysis. Later, FSCPs were introduced onto the aminolyzed P(3HB-co-4HB) scaffolds. Introduction of the FSCP groups was verified using Fourier transform infrared spectroscopy and the ninhydrin method. The effect of the incorporation of FSCPs on hydrophilicity was investigated using the water contact angle. As the concentration of FSCPs increased, the water contact angle decreased. In vitro study demonstrated that P(3HB-co-4HB)/FSCP scaffolds provided better cell attachment and growth of L929 mouse fibroblast cells and better cell proliferation.

AB - The time-dependent behaviour of sodium and chlorine was studied as a spinoff from a study of aluminum in the hand of subjects suffering from Alzheimer's disease and a control group, involving 15 Alzheimer's and 16 control subjects with an age range of 63-89 years. This was achieved using the in vivo neutron activation analysis system developed at McMaster University for the non-invasive measurement of aluminum, where a subject's hand is placed in a beam of accelerator-based thermalized neutrons, which activates elements by neutron capture. Following irradiation, the subject's hand is placed in a detection system comprising 9 NaI(Tl) detectors arranged in a 4pi geometry to measure activated elements. The redistribution half-lives of the activation products 24Na and 38Cl from the hand were determined after correction for the physical half-life, by means of sequential analysis of the residual activity in the hand. The kinetic behaviours of sodium and chlorine were best characterized by an exponential function corresponding to the rapidly exchangeable pool. The mean redistribution half lives from the hand for sodium and chlorine in the control subjects were 40.5 +/ 17.4 min and 24.2 +/- 8.5 min, respectively. For Alzheimer's disease subjects the mean redistribution half-lives were 58.2 +/- 36.1 min for sodium and 33.6 +/- 16.7 min for chlorine. There was no significant difference in chlorine and sodium redistribution half-lives between the Alzheimer's disease and control group subjects. These results are promising, given that the irradiation and counting protocol were optimized for the aluminum study, rendering them suboptimal for analyzing other elements and their rate of change with time. Further improvements include optimizing the irradiation protocol, longer counting times, and measuring the activity in the un-irradiated hand in various time intervals following irradiation.

AB - During the past decade, the authors have collected a few X-ray diffraction data sets from protein crystals that appeared to be easy cases of molecular replacement but failed to yield structures even after extensive trials. Here, the use of a large-scale molecular replacement method that explores all structurally characterized domains as phasing models to determine the structure corresponding to two data sets collected at 1.9 and 2.3 A resolution is reported. These two structures were of the same protein independently crystallized in 2007 and 2011. The structures derived are virtually identical and were found to consist of two compact globular domains connected by a hinge. The high resolution of one of these data sets enabled inference of the amino-acid sequence from the electron density map. The deduced sequence is nearly identical to that of a protein from the multidrug-resistant bacterium Stenotrophomonas maltophilia. Although the structure of this protein has not been determined previously, it is homologous to the well studied DING proteins which mediate the cellular uptake of phosphate ions. The final electron-density maps from both of the data sets revealed a large density at the interface of the two globular domains that is likely to represent a phosphate ion. Thus, the structure is likely to be that of a phosphate-binding protein encoded by the S. maltophilia genome (SmPBP; PDB entry 5j1d). The nature of the phosphate-binding site of SmPBP closely resembles that of Pseudomonas fluorescens DING (PfluDING), which displays remarkable discrimination between the closely similar phosphate and arsenate ions. The results presented here illustrate that routine crystallization trials may occasionally lead to the serendipitous crystallization of a protein of unknown identity and brute-force molecular replacement through 'fold space' might allow the identification of the unknown protein. PMID- 27710930 TI - Online ion-exchange chromatography for small-angle X-ray scattering. AB - Biological small-angle X-ray scattering (BioSAXS) is a powerful technique to determine the solution structure, particle size, shape and surface-to-volume ratio of macromolecules. However, a drawback is that the sample needs to be monodisperse. To ensure this, size-exclusion chromatography (SEC) has been implemented on many BioSAXS beamlines. Here, the integration of ion-exchange chromatography (IEC) using both continuous linear and step gradients on a beamline is described. Background subtraction for continuous gradients by shifting a reference measurement and two different approaches for step gradients, which are based on interpolating between two background measurements, are discussed. The results presented here serve as a proof of principle for online IEC and subsequent data treatment. PMID- 27710931 TI - Crystal structures of the disulfide reductase DsbM from Pseudomonas aeruginosa. AB - In bacteria, many Dsb-family proteins play diverse roles in the conversion between the oxidized and reduced states of cysteine residues of substrate proteins. Most Dsb enzymes catalyze disulfide formation in periplasmic or secreted substrate proteins. Recently, a DsbM protein has been found in a Gram negative bacterium, and was characterized as a cytosolic Dsb member with the conserved CXXC motif on the basis of sequence homology to the Dsb-family proteins. The protein was implicated in the reduction of the cytoplasmic redox sensor protein OxyR in Pseudomonas aeruginosa. Here, crystal structures of DsbM from P. aeruginosa are presented, revealing that it consists of a modified thioredoxin domain containing the CXXC motif and a lid domain surrounding the CXXC motif. In a glutathione-linked structure, a glutathione molecule is linked to the CXXC motif of DsbM and is bound in an elongated cavity region in the thioredoxin domain, which is also suited for substrate peptide binding. A striking structural similarity to a human glutathione S-transferase was found in the glutathione-binding pocket. Further, biochemical evidence is presented suggesting that DsbM is directly involved in the reduction of the disulfide of Cys199 and Cys208 in OxyR, resulting in the acceleration of OxyR reduction in the absence of reactive oxygen species stress. These findings may help to expand the understanding of the diverse roles of redox-related proteins that contain the CXXC motif. PMID- 27710932 TI - Validation and correction of Zn-CysxHisy complexes. AB - Many crystal structures in the Protein Data Bank contain zinc ions in a geometrically distorted tetrahedral complex with four Cys and/or His ligands. A method is presented to automatically validate and correct these zinc complexes. Analysis of the corrected zinc complexes shows that the average Zn-Cys distances and Cys-Zn-Cys angles are a function of the number of cysteines and histidines involved. The observed trends can be used to develop more context-sensitive targets for model validation and refinement. PMID- 27710933 TI - Empirical power laws for the radii of gyration of protein oligomers. AB - The radius of gyration is a fundamental structural parameter that is particularly useful for describing polymers. It has been known since Flory's seminal work in the mid-20th century that polymers show a power-law dependence, where the radius of gyration is proportional to the number of residues raised to a power. The power-law exponent has been measured experimentally for denatured proteins and derived empirically for folded monomeric proteins using crystal structures. Here, the biological assemblies in the Protein Data Bank are surveyed to derive the power-law parameters for protein oligomers having degrees of oligomerization of 2 6 and 8. The power-law exponents for oligomers span a narrow range of 0.38-0.41, which is close to the value of 0.40 obtained for monomers. This result shows that protein oligomers exhibit essentially the same power-law behavior as monomers. A simple power-law formula is provided for estimating the oligomeric state from an experimental measurement of the radius of gyration. Several proteins in the Protein Data Bank are found to deviate substantially from power-law behavior by having an atypically large radius of gyration. Some of the outliers have highly elongated structures, such as coiled coils. For coiled coils, the radius of gyration does not follow a power law and instead scales linearly with the number of residues in the oligomer. Other outliers are proteins whose oligomeric state or quaternary structure is incorrectly annotated in the Protein Data Bank. The power laws could be used to identify such errors and help prevent them in future depositions. PMID- 27710934 TI - Manipulation of an existing crystal form unexpectedly results in interwoven packing networks with pseudo-translational symmetry. AB - Nonribosomal peptide synthetases (NRPSs) are multimodular enzymes that synthesize a myriad of diverse molecules. Tailoring domains have been co-opted into NRPSs to introduce further variety into nonribosomal peptide products. Linear gramicidin synthetase contains a unique formylation-tailoring domain in its initiation module (F-A-PCP). The structure of the F-A di-domain has previously been determined in a crystal form which had large solvent channels and no density for the minor Asub subdomain. An attempt was made to take advantage of this packing by removing the Asub subdomain from the construct (F-ADeltasub) in order to produce a crystal that could accommodate the PCP domain. In the resulting crystal the original packing network was still present, but a second network with the same packing and almost no contact with the original network took the place of the solvent channels and changed the space group of the crystal. PMID- 27710935 TI - PRISM-EM: template interface-based modelling of multi-protein complexes guided by cryo-electron microscopy density maps. AB - The structures of protein assemblies are important for elucidating cellular processes at the molecular level. Three-dimensional electron microscopy (3DEM) is a powerful method to identify the structures of assemblies, especially those that are challenging to study by crystallography. Here, a new approach, PRISM-EM, is reported to computationally generate plausible structural models using a procedure that combines crystallographic structures and density maps obtained from 3DEM. The predictions are validated against seven available structurally different crystallographic complexes. The models display mean deviations in the backbone of <5 A. PRISM-EM was further tested on different benchmark sets; the accuracy was evaluated with respect to the structure of the complex, and the correlation with EM density maps and interface predictions were evaluated and compared with those obtained using other methods. PRISM-EM was then used to predict the structure of the ternary complex of the HIV-1 envelope glycoprotein trimer, the ligand CD4 and the neutralizing protein m36. PMID- 27710936 TI - Automated refinement of macromolecular structures at low resolution using prior information. AB - Since the ratio of the number of observations to adjustable parameters is small at low resolution, it is necessary to use complementary information for the analysis of such data. ProSMART is a program that can generate restraints for macromolecules using homologous structures, as well as generic restraints for the stabilization of secondary structures. These restraints are used by REFMAC5 to stabilize the refinement of an atomic model. However, the optimal refinement protocol varies from case to case, and it is not always obvious how to select appropriate homologous structure(s), or other sources of prior information, for restraint generation. After running extensive tests on a large data set of low resolution models, the best-performing refinement protocols and strategies for the selection of homologous structures have been identified. These strategies and protocols have been implemented in the Low-Resolution Structure Refinement (LORESTR) pipeline. The pipeline performs auto-detection of twinning and selects the optimal scaling method and solvent parameters. LORESTR can either use user supplied homologous structures, or run an automated BLAST search and download homologues from the PDB. The pipeline executes multiple model-refinement instances using different parameters in order to find the best protocol. Tests show that the automated pipeline improves R factors, geometry and Ramachandran statistics for 94% of the low-resolution cases from the PDB included in the test set.

AB - Glutaredoxins (Grxs) constitute a superfamily of proteins that perform diverse biological functions. The Saccharomyces cerevisiae glutaredoxin Grx6 not only serves as a glutathione (GSH)-dependent oxidoreductase and as a GSH transferase, but also as an essential [2Fe-2S]-binding protein. Here, the dimeric structure of the C-terminal domain of Grx6 (holo Grx6C), bridged by one [2Fe-2S] cluster coordinated by the active-site Cys136 and two external GSH molecules, is reported. Structural comparison combined with multiple-sequence alignment demonstrated that holo Grx6C is similar to the [2Fe-2S] cluster-incorporated dithiol Grxs, which share a highly conserved [2Fe-2S] cluster-binding pattern and dimeric conformation that is distinct from the previously identified [2Fe-2S] cluster-ligated monothiol Grxs.

AB - Receptor-like cytoplasmic kinases (RLCKs) in Arabidopsis play a central role in the integration of signaling input from various growth and immune signaling pathways. BOTRYTIS-INDUCED KINASE 1 (BIK1), belonging to the RLCK family, is an important player in defense against bacterial and fungal pathogens and in ethylene and brassinosteroid hormone signaling. In this study, the purification and crystallization of a first member of the class VI family of RLCK proteins, BIK1, are reported. BIK1 was crystallized using the microbatch-under-oil method. X-ray diffraction data were collected to 2.35 A resolution. The crystals belonged to the monoclinic space group C2, with two monomers per asymmetric unit. PMID- 27710939 TI - Crystal and solution structural studies of mouse phospholipid hydroperoxide glutathione peroxidase 4. AB - The mammalian glutathione peroxidase (GPx) family is a key component of the cellular antioxidative defence system. Within this family, GPx4 has unique features as it accepts a large class of hydroperoxy lipid substrates and has a plethora of biological functions, including sperm maturation, regulation of apoptosis and cerebral embryogenesis. In this paper, the structure of the cytoplasmic isoform of mouse phospholipid hydroperoxide glutathione peroxidase (O70325-2 GPx4) with selenocysteine 46 mutated to cysteine is reported solved at 1.8 A resolution using X-ray crystallography. Furthermore, solution data of an isotope-labelled GPx protein are presented. PMID- 27710940 TI - The structure of a glycoside hydrolase 29 family member from a rumen bacterium reveals unique, dual carbohydrate-binding domains. AB - Glycoside hydrolase (GH) family 29 consists solely of alpha-L-fucosidases. These enzymes catalyse the hydrolysis of glycosidic bonds. Here, the structure of GH29_0940, a protein cloned from metagenomic DNA from the rumen of a cow, has been solved, which reveals a multi-domain arrangement that has only recently been identified in bacterial GH29 enzymes. The microbial species that provided the source of this enzyme is unknown. This enzyme contains a second carbohydrate binding domain at its C-terminal end in addition to the typical N-terminal catalytic domain and carbohydrate-binding domain arrangement of GH29-family proteins. GH29_0940 is a monomer and its overall structure consists of an N terminal TIM-barrel-like domain, a central beta-sandwich domain and a C-terminal beta-sandwich domain. The TIM-barrel-like catalytic domain exhibits a (beta/alpha)8/7 arrangement in the core instead of the typical (beta/alpha)8 topology, with the 'missing' alpha-helix replaced by a long meandering loop that 'closes' the barrel structure and suggests a high degree of structural flexibility in the catalytic core. This feature was also noted in all six other structures of GH29 enzymes that have been deposited in the PDB. Based on sequence and structural similarity, the residues Asp162 and Glu220 are proposed to serve as the catalytic nucleophile and the proton donor, respectively. Like other GH29 enzymes, the GH29_0940 structure shows five strictly conserved residues in the catalytic pocket. The structure shows two glycerol molecules in the active site, which have also been observed in other GH29 structures, suggesting that the enzyme catalyses the hydrolysis of small carbohydrates. The two binding domains are classed as family 32 carbohydrate-binding modules (CBM32). These domains have residues involved in ligand binding in the loop regions at the edge of the beta sandwich. The predicted substrate-binding residues differ between the modules, suggesting that different modules bind to different groups on the substrate(s). Enzymes that possess multiple copies of CBMs are thought to have a complex mechanism of ligand recognition. Defined electron density identifying a long 20 amino-acid hydrophilic loop separating the two CBMs was observed. This suggests that the additional C-terminal domain may have a dynamic range of movement enabled by the loop, allowing a unique mode of action for a GH29 enzyme that has not been identified previously.

AB - Huntington's disease is one of nine neurodegenerative diseases caused by a polyglutamine (polyQ)-repeat expansion. An anti-polyQ antigen-binding fragment, MW1 Fab, was crystallized both on Earth and on the International Space Station, a microgravity environment where convection is limited. Once the crystals returned to Earth, the number, size and morphology of all crystals were recorded, and X ray data were collected from representative crystals. The results generally agreed with previous microgravity crystallization studies. On average, microgravity-grown crystals were 20% larger than control crystals grown on Earth, and microgravity-grown crystals had a slightly improved mosaicity (decreased by 0.03 degrees ) and diffraction resolution (decreased by 0.2 A) compared with control crystals grown on Earth. However, the highest resolution and lowest mosaicity crystals were formed on Earth, and the highest-quality crystal overall was formed on Earth after return from microgravity. PMID- 27710942 TI - Crystal structure of rofecoxib bound to human cyclooxygenase-2. AB - Rofecoxib (Vioxx) was one of the first selective cyclooxygenase-2 (COX-2) inhibitors (coxibs) to be approved for use in humans. Within five years after its release to the public, Vioxx was withdrawn from the market owing to the adverse cardiovascular effects of the drug. Despite the widespread knowledge of the development and withdrawal of Vioxx, relatively little is known at the molecular level about how the inhibitor binds to COX-2. Vioxx is unique in that the inhibitor contains a methyl sulfone moiety in place of the sulfonamide moiety found in other coxibs such as celecoxib and valdecoxib. Here, new crystallization conditions were identified that allowed the structural determination of human COX 2 in complex with Vioxx and the structure was subsequently determined to 2.7 A resolution. The crystal structure provides the first atomic level details of the binding of Vioxx to COX-2. As anticipated, Vioxx binds with its methyl sulfone moiety located in the side pocket of the cyclooxygenase channel, providing support for the isoform selectivity of this drug. PMID- 27710943 TI - Crystallographic study of the 2-thioribothymidine-synthetic complex TtuA-TtuB from Thermus thermophilus. AB - The ubiquitin-like protein TtuB is a sulfur carrier for the biosynthesis of 2 thioribothymidine (s2T) at position 54 in some thermophilic bacterial tRNAs. TtuB captures a S atom at its C-terminus as a thiocarboxylate and transfers it to tRNA by the transferase activity of TtuA. TtuB also functions to suppress s2T formation by forming a covalent bond with TtuA. To explore how TtuB interacts with TtuA and switches between these two different functions, high-resolution structure analysis of the TtuA-TtuB complex is required. In this study, the TtuA TtuB complex from Thermus thermophilus was expressed, purified and crystallized. To mimic the thiocarboxylated TtuB, the C-terminal Gly residue was replaced with Cys (G65C) to obtain crystals of the TtuA-TtuB complex. A Zn-MAD data set was collected to a resolution of 2.5 A. MAD analysis successfully determined eight Zn sites, and a partial structure model composed of four TtuA-TtuB complexes in the asymmetric unit was constructed. PMID- 27710945 TI - Biochemical, spectroscopic and X-ray structural analysis of deuterated multicopper oxidase CueO prepared from a new expression construct for neutron crystallography. AB - Multicopper oxidases oxidize various phenolic and nonphenolic compounds by using molecular oxygen as an electron acceptor to produce water. A multicopper oxidase protein, CueO, from Escherichia coli is involved in copper homeostasis in the bacterial cell. Although X-ray crystallographic studies have been conducted, the reduction mechanism of oxygen and the proton-transfer pathway remain unclear owing to the difficulty in identifying H atoms from X-ray diffraction data alone. To elucidate the reaction mechanism using neutron crystallography, a preparation system for obtaining large, high-quality single crystals of deuterated CueO was developed. Tiny crystals were obtained from the deuterated CueO initially prepared from the original construct. The X-ray crystal structure of the deuterated CueO showed that the protein contained an incompletely truncated signal sequence at the N-terminus, which resulted in the heterogeneity of the protein sample for crystallization. Here, a new CueO expression system that had an HRV3C cleavage site just after the signal sequence was constructed. Deuterated CueO from the new construct was expressed in cells cultured in deuterated algae extract medium and the signal sequence was completely eliminated by HRV3C protease. The deuteration level of the purified protein was estimated by MALDI TOF mass spectrometry to be at least 83.2% compared with nondeuterated protein. Nondeuterated CueO crystallized in space group P21, with unit-cell parameters a = 49.51, b = 88.79, c = 53.95 A, beta = 94.24 degrees , and deuterated CueO crystallized in space group P212121, with unit-cell parameters a = 49.91, b = 106.92, c = 262.89 A. The crystallographic parameters for the crystals of the new construct were different from those previously reported for nondeuterated crystals. The nondeuterated and deuterated CueO from the new construct had similar UV-Vis spectra, enzymatic activities and overall structure and geometry of the ligands of the Cu atoms in the active site to those of previously reported CueO structures. These results indicate that the CueO protein prepared using the new construct is suitable for further neutron diffraction studies. PMID- 27710944 TI - X-ray crystallographic studies of the extracellular domain of the first plant ATP receptor, DORN1, and the orthologous protein from Camelina sativa. AB - Does not respond to nucleotides 1 (DORN1) has recently been identified as the first membrane-integral plant ATP receptor, which is required for ATP-induced calcium response, mitogen-activated protein kinase activation and defense responses in Arabidopsis thaliana. In order to understand DORN1-mediated ATP sensing and signal transduction, crystallization and preliminary X-ray studies were conducted on the extracellular domain of DORN1 (atDORN1-ECD) and that of an orthologous protein, Camelina sativa lectin receptor kinase I.9 (csLecRK-I.9-ECD or csI.9-ECD). A variety of deglycosylation strategies were employed to optimize the glycosylated recombinant atDORN1-ECD for crystallization. In addition, the glycosylated csI.9-ECD protein was crystallized at 291 K. X-ray diffraction data were collected at 4.6 A resolution from a single crystal. The crystal belonged to space group C222 or C2221, with unit-cell parameters a = 94.7, b = 191.5, c = 302.8 A. These preliminary studies have laid the foundation for structural determination of the DORN1 and I.9 receptor proteins, which will lead to a better understanding of the perception and function of extracellular ATP in plants.

AB - GDP-D-mannose pyrophosphorylase catalyzes the production of GDP-D-mannose, an intermediate product in the plant ascorbic acid (AsA) biosynthetic pathway. This enzyme is a key regulatory target in AsA biosynthesis and is encoded by VITAMIN C DEFECTIVE 1 (VTC1) in the Arabidopsis thaliana genome. Here, recombinant VTC1 was expressed, purified and crystallized. Diffraction data were obtained from VTC1 crystals grown in the absence and presence of substrate using X-rays. The ligand free VTC1 crystal diffracted X-rays to 3.3 A resolution and belonged to space group R32, with unit-cell parameters a = b = 183.6, c = 368.5 A, alpha = beta = 90, gamma = 120 degrees ; the crystal of VTC1 in the presence of substrate diffracted X-rays to 1.75 A resolution and belonged to space group P21, with unit cell parameters a = 70.8, b = 83.9, c = 74.5 A, alpha = gamma = 90.0, beta = 114.9 degrees .

The presence of this variation may cause untoward hemorrhages, if accidentally nicked. Therefore, it is important for otologists to be aware of this entity, and its relative anatomy, to avoid any unexpected complication. We present a case of a 7-year-old girl who presented with right sided microtia with membranous atresia. METHODS: High-resolution computed tomographic scan and three-dimensional reconstruction of the temporal bone showed bilateral enlarged SAA. RESULTS: The width of the right-sided bone canal was between 0.76 and 1.33 mm. The left temporal bone showed the same variation, with the width of the canal consistently greater than 1.0 mm, ranging from 1.07 to 1.23 mm in greatest transverse dimension. CONCLUSIONS: The variation proposed in microtia was not previously reported in the literature, which may have important implications for the canal reconstruction. PMID- 27710956 TI - Interstitial NORs, Fragile Sites, and Chromosome Evolution: A Not So Simple Relationship - The Example of Melolontha melolontha and Genus Protaetia (Coleoptera: Scarabaeidae). AB - In the present study, the origin of recurrent rearrangements involving chromosome 6 in 3.2% of cells of Melolontha melolontha (Coleoptera, Scarabaeidae) was investigated. Various chromosome staining techniques, including C-banding, Giemsa and silver staining, as well as fluorescence in situ hybridization with a human 28S rDNA probe, were applied to M. melolontha chromosome spreads. In addition, related species of the genera Melolontha and Protaetia were studied. On chromosome 6 of M. melolontha, there is a fragile site-like structure which corresponds to an interstitial nucleolus organizer region (NOR). Despite this instability, the NOR remains unique and interstitial in this species, as well as in the other species studied. It is proposed that the intercalary position of the NOR both facilitates the detection of its fragile site-like instability and correlates with its relative stability during evolution. We explain this apparent paradox by strong counter-selection for imbalances of the chromosome fragment distal to the interstitial NORs, which would recurrently occur in the progeny of translocation carriers. Thus, the frequent telomeric position of the NORs in most animal and plant taxa would have no functional rationale but would be the consequence of selection against the meiotic transmission of chromosome imbalances.

AB - The monophyletic order Osteoglossiformes represents one of the most ancestral groups of teleosts and has at least 1 representative in all continents of the southern hemisphere, with the exception of Antarctica. However, despite its phylogenetic and biogeographical importance, cytogenetic data in Osteoglossiformes are scarce. Here, karyotype and chromosomal characteristics of the lower Niger River population of the African butterfly fish Pantodon buchholzi, the sole species of the family Pantodontidae (Osteoglossiformes), were examined using conventional and molecular cytogenetic approaches. All specimens examined had 2n = 46 chromosomes, with a karyotype composed of 5 pairs of metacentric, 5 pairs of submetacentric, and 13 pairs of acrocentric chromosomes in both sexes. No morphologically differentiated sex chromosomes were identified. C-bands were located in the centromeric/pericentromeric region of all chromosomes and were associated with the single AgNOR site. FISH with ribosomal DNA probes revealed that both 5S and 18S rDNA were present in only 1 pair of chromosomes each, but did not colocalize. CMA3+ bands were observed near the telomeres in several chromosome pairs and also at the 18S rDNA sites. The mapping of di- and trinucleotide repeat motifs, Rex6 transposable element, and U2 snRNA showed a scattered distribution over most of the chromosomes, but for some microsatellites and the U2 snRNA also a preferential accumulation at telomeric regions. This study presents the first detailed cytogenetic analysis in the African butterfly fish by both conventional and molecular cytogenetic protocols. This is the first of a series of further cytogenetic and cytogenomic studies on osteoglossiforms, aiming to comprehensively examine the chromosomal evolution in this phylogenetically important fish order.

AB - Non-transfusion-dependent thalassemia (NTDT) is associated with various forms of thalassemia and genetic modifiers. We report the molecular basis of NTDT in hemoglobin (Hb) E-beta-thalassemia disease. This study was done in 73 adult patients encountered at the prenatal diagnosis center of Khon Kaen University, Northeast Thailand. Hematological parameters and Hb patterns were collected, and alpha- and beta-globin gene mutations were determined. Multiple single-nucleotide polymorphisms (SNPs) including the rs7482144/Ggamma-XmnI polymorphism, rs2297339, rs2838513, rs4895441, and rs9399137 in the HBS1L-MYB gene, rs4671393 and rs11886868 in the BCL11A gene, and G176AfsX179 in the KLF1 gene were examined. Five beta0-thalassemia mutations and a severe beta+-thalassemia mutation in trans to the betaE gene were identified. No significant difference in hematological parameters was observed among beta-thalassemia genotypes. Coinheritance of alpha thalassemia was observed in 31 of the 73 subjects (42.5%). Four SNPs including Ggamma-XmnI, rs2297339, rs4895441, and rs9399137 of HBS1L-MYB were found to be associated with high Hb F levels in 39 (53.4%) subjects. The molecular basis of NTDT in the remaining 3 (4.1%) cases could not be defined. These results indicate multiple genetic factors in NTDT patients and underline the importance of complete genotyping to provide proper management, make clinical predictions, and improve genetic counseling. PMID- 27710962 TI - Voltage-Gated Potassium Channel Antibodies in Slow-Progression Motor Neuron Disease. AB - BACKGROUND: The spectrum of autoimmune neurological diseases associated with voltage-gated potassium channel (VGKC)-complex antibodies (Abs) ranges from peripheral nerve disorders to limbic encephalitis. Recently, low titers of VGKC complex Abs have also been reported in neurodegenerative disorders, but their clinical relevance is unknown. OBJECTIVE: The aim of the study was to explore the prevalence of VGKC-complex Abs in slow-progression motor neuron disease (MND). METHODS: We compared 11 patients affected by slow-progression MND with 9 patients presenting typical progression illness. Sera were tested for VGKC-complex Abs by radioimmunoassay. The distribution of VGKC-complex Abs was analyzed with the Mann Whitney U test. RESULTS: The statistical analysis showed a significant difference between the mean values in the study and control groups. A case with long survival MND harboring VGKC-complex Abs and treated with intravenous immunoglobulins is described. CONCLUSION: Although VGKC-complex Abs are not likely to be pathogenic, these results could reflect the coexistence of an immunological activation in patients with slow disease progression. PMID- 27710963 TI - Defining Subpopulations of Arcuate Nucleus GABA Neurons in Male, Female, and Prenatally Androgenized Female Mice. AB - BACKGROUND/AIMS: Arcuate nucleus (ARN) gamma-aminobutyric acid (GABA) neurons are implicated in many critical homeostatic mechanisms, from food intake to fertility. To determine the functional relevance of ARN GABA neurons, it is essential to define the neurotransmitters co-expressed with and potentially co released from ARN GABA neurons. METHODS: The present study investigated the expression of markers of specific signaling molecules by ARN GABA neurons in brain sections from male, female, and, in some cases, prenatally androgen-treated (PNA) female, vesicular GABA transporter (VGaT)-ires-Cre/tdTomato reporter mice. Immunofluorescence for kisspeptin, beta-endorphin, neuropeptide Y (NPY), tyrosine hydroxylase (TH) and neuronal nitric oxide synthase (nNOS) was detected by confocal microscopy, and co-localization with tdTomato VGaT reporter expression throughout the ARN was quantified. RESULTS: GABA neurons rarely co-localized with kisspeptin (<2%) or beta-endorphin (<1%), and only a small proportion of kisspeptin (~10%) or beta-endorphin (~3%) neurons co-localized with VGaT in male and female mice. In contrast, one-third of ARN GABA neurons co-localized with NPY, and nearly all NPY neurons (>95%) co-localized with VGaT across groups. Both TH and nNOS labeling was co-localized with ~10% of ARN GABA neurons. The proportion of TH neurons co-localized with VGaT was significantly greater in males than either control or PNA females, and the proportion of nNOS neurons co localizing VGaT was higher in control and PNA females compared with males. CONCLUSION: These data highlight NPY as a significant subpopulation of ARN GABA neurons, demonstrate no significant impact of PNA on signal co-expression, and, for the first time, show sexually dimorphic co-expression patterns of TH and nNOS with ARN GABA neurons. PMID- 27710964 TI - Stress Effects in Vowel Perception as a Function of Language-Specific Vocabulary Patterns. AB - BACKGROUND/AIMS: Evidence from spoken word recognition suggests that for English listeners, distinguishing full versus reduced vowels is important, but discerning stress differences involving the same full vowel (as in mu- from music or museum) is not. In Dutch, in contrast, the latter distinction is important. This difference arises from the relative frequency of unstressed full vowels in the two vocabularies. The goal of this paper is to determine how this difference in the lexicon influences the perception of stressed versus unstressed vowels. METHODS: All possible sequences of two segments (diphones) in Dutch and in English were presented to native listeners in gated fragments. We recorded identification performance over time throughout the speech signal. The data were here analysed specifically for patterns in perception of stressed versus unstressed vowels. RESULTS: The data reveal significantly larger stress effects (whereby unstressed vowels are harder to identify than stressed vowels) in English than in Dutch. Both language-specific and shared patterns appear regarding which vowels show stress effects. CONCLUSION: We explain the larger stress effect in English as reflecting the processing demands caused by the difference in use of unstressed vowels in the lexicon. The larger stress effect in English is due to relative inexperience with processing unstressed full vowels. PMID- 27710965 TI - The Role of Biogenic Amines in the Regulation of Interaction between the Immune and Nervous Systems in Multiple Sclerosis. AB - OBJECTIVE: Multiple sclerosis (MS) is a demyelinating, presumably autoimmune disease of the central nervous system. Biogenic amines may participate in MS pathogenesis modulating immune cell activity and cytokine production. METHODS: Forty-three patients with relapsing-remitting MS were examined. Serotonin (SE), norepinephrine (NE) and epinephrine (EPI) concentrations in sera were measured by ELISA. The functional activity of Th17 and Th1 cells was assessed by the ability of peripheral blood mononuclear cells (PBMCs) to produce interferon-gamma (IFN gamma) and interleukin-17 (IL-17) and cell proliferation upon stimulation with microbeads coated with anti-CD3 and anti-CD28 antibodies. To evaluate the effect of biogenic amines on Th17 and Th1 cells, PBMCs were cultured in the presence of SE and NE. Statistical analysis was performed using Prism 6 software. RESULTS: Concentrations of SE and EPI in sera were not different between the groups. Concentrations of NE in sera from MS patients were lower than those in the healthy control group. The production of IL-17 and IFN-gamma in MS patients in relapse was higher than that in patients in remission or in the control group. SE at a concentration of 10-4M suppressed IL-17 production. NE at a concentration of 10-4M suppressed both IL-17 and IFN-gamma production. CONCLUSIONS: These data suggest an anti-inflammatory role for biogenic amines in MS. PMID- 27710967 TI - Clot Formation in the Presence of Acetylsalicylic Acid Leads to Increased Lysis Rates Regardless of the Chosen Thrombolysis Strategy. AB - BACKGROUND: Patients with acute ischemic strokes frequently take an acetylsalicylic acid (ASA) premedication. We determined the impact of ASA on different thrombolysis strategies in vitro. METHODS: For two clot types made from platelet-rich plasma (one with and one without ASA) lysis rates were measured by weight loss after 1 h for five different groups: in control group A clots were solely placed in plasma; in groups B and C clots were treated with rt-PA (60 kU/ml), and in groups D and E clots were treated with desmoteplase (DSPA; 2 ug/ml). Ultrasound (2 MHz, 0.179 W/cm2) was included in groups C and E. The fibrin mesh structures of the clots were investigated by electron microscopy. RESULTS: For both clot types lysis rates increased significantly for all treatment strategies compared to their control group (each p < 0.001). The addition of ASA significantly increased the lysis rate in all 5 groups (each p < 0.001) and led to a ceiling effect concerning the treatment. A semiquantitative analysis of transmission electron micrographs revealed a decreased fibrin density for clots with ASA. For both clot types DSPA and ultrasound led to a significant dissolution of the fibrin mesh (both p = 0.029). CONCLUSIONS: In vitro ASA pretreatment leads to significantly increased lysis rates due to a weaker fibrin mesh in platelet-rich plasma clots. PMID- 27710966 TI - Kcne4 Deletion Sex-Dependently Alters Vascular Reactivity. AB - Voltage-gated potassium (Kv) channels formed by Kv7 (KCNQ) alpha-subunits are recognized as crucial for vascular smooth muscle function, in addition to their established roles in the heart (Kv7.1) and the brain (Kv7.2-5). In vivo, Kv7 alpha-subunits are often regulated by KCNE subfamily ancillary (beta) subunits. We investigated the effects of targeted germline Kcne4 deletion on mesenteric artery reactivity in adult male and female mice. Kcne4 deletion increased mesenteric artery contractility in response to alpha-adrenoceptor agonist methoxamine, and decreased responses to Kv7.2-7.5 channel activator ML213, in male but not female mice. In contrast, Kcne4 deletion markedly decreased vasorelaxation in response to isoprenaline in both male and female mice. Kcne4 expression was 2-fold lower in the female versus the male mouse mesenteric artery, and Kcne4 deletion elicited only moderate changes of other Kcne transcripts, with no striking sex-specific differences. However, Kv7.4 protein expression in females was twice that in males, and was reduced in both sexes by Kcne4 deletion. Our findings confirm a crucial role for KCNE4 in regulation of Kv7 channel activity to modulate vascular tone, and provide the first known molecular mechanism for sex-specificity of this modulation that has important implications for vascular reactivity and may underlie sex-specific susceptibility to cardiovascular diseases. PMID- 27710968 TI - Endometriotic Pain Is Associated with Adenomyosis but Not with the Compartments Affected by Deep Infiltrating Endometriosis. AB - BACKGROUND: The identification of presurgical clinical markers may be helpful to allow the staging of endometriosis severity. It has been suggested that pain characteristics orientate the gynecologist about the anatomical involvement of endometriosis. The study was performed to analyze the correlation between pain symptoms and the anatomical location of endometriosis. METHODS: One hundred fifty five consecutive patients with a complete removal of deep infiltrating endometriosis (DIE) were included. Prior to surgery, data on patient and disease characteristics were obtained. The intensity of the pain symptoms was registered using a Visual Analogue Scale. The endometriotic lesions were categorized according to the Enzian morphological classification. Correlation and multivariate analysis were performed to assess the potential associations between pain characteristics (dysmenorrhea, pelvic pain, dyschezia, dyspareunia or dysuria) and the location of endometriosis or other disease-related characteristics (hematuria, rectal bleeding or adenomyosis). RESULTS: Pelvic pain was significantly associated with the presence of adenomyosis. Dyschezia was correlated with rectal bleeding and dysuria with the presence of hematuria. No relationship was found between other kinds of pain and the morphological location of endometriosis or other disease-related characteristics. CONCLUSION: Our data suggest that pelvic pain is correlated with the presence of adenomyosis in women with DIE. Further studies are required. PMID- 27710969 TI - Familial Brain Periventricular Pseudocysts. AB - INTRODUCTION: We report the rare finding of recurrent periventricular pseudocysts (PVPC) in consecutive pregnancies in 4 families and their postnatal outcome. MATERIALS AND METHODS: We reviewed the databases of 3 large ultrasound units searching for the diagnosis of PVPC in 2 pregnancies of the same patient. RESULTS: The first case of recurrent PVPC was diagnosed in 2011 and since then 3 additional families were diagnosed (8 cases of PVPC all in all). All fetuses underwent fetal MRI that confirmed the presence of frontal or frontocaudal PVPC. Amniocentesis, when performed, demonstrated a normal karyotype. Termination of pregnancy was carried out in 2 pregnancies in 2 of 4 families. The remaining 6 pregnancies ended with a term delivery, and to date all babies are developing normally. CONCLUSION: The rare finding of recurrent brain PVPC in consecutive pregnancies raises the possibility of a hereditary etiology as opposed to a sporadic event. As in isolated PVPC, frontocaudal 'familial PVPC' appears to carry a favorable prognosis. PMID- 27710970 TI - Chemotherapy in Non-Small Cell Lung Cancer Patients Receiving Oxygen Therapy. AB - BACKGROUND: Information regarding chemotherapy in non-small cell lung cancer (NSCLC) patients with chronic respiratory failure is limited. PATIENTS AND METHODS: We retrospectively analyzed patients who received oxygen therapy and underwent chemotherapy for NSCLC at our hospital. RESULTS: 6 patients with NSCLC receiving oxygen therapy (4 with unresectable lung cancer and 2 with postoperative recurrent lung cancer) underwent chemotherapy. 1 patient achieved a partial response and 1 achieved stable disease after first-line chemotherapy. The median overall survival (OS) was 247 days in all patients. Patients with unresectable NSCLC and recurrent NSCLC had median OS times of 282 and 239 days, respectively. Grade 3 lung infection occurred in 4 patients during chemotherapy treatment; however, there were no chemotherapy-related deaths. CONCLUSION: There is a possibility that chemotherapy could improve the survival of NSCLC patients who receive oxygen therapy. PMID- 27710971 TI - Prognostic Role of Lactate Dehydrogenase Expression in Urologic Cancers: A Systematic Review and Meta-Analysis. AB - OBJECTIVE: The prognostic role of lactate dehydrogenase (LDH) in urinary system cancer is still controversial. Thus, we conducted a meta-analysis to assess the prognostic significance of LDH for patients with urinary system cancer. METHODS: We searched the PubMed, Embase, Springer and CNKI databases for studies published from January 1991 to February 2015 associated with LDH and urinary system cancer. Study quality was assessed using the Newcastle-Ottawa Scale. After careful review, survival data were extracted from eligible studies. We used pooled hazard ratios (HRs) to estimate the effect of LDH on overall survival (OS) and progression-free survival (PFS). RESULTS: 44 studies meeting the criterion were included. High expression of LDH was significantly correlated with poor OS in urologic cancer (pooled HR 1.93, 95% confidence interval (CI) 1.81-2.07; p < 0.001). The pooled HRs showed significant difference in PFS between LDH over expression group with LDH low expression group (Pooled HR 1.95, 95% CI 1.61-2.36; p < 0.001) in urologic cancer. CONCLUSION: High serum LDH is associated with OS and PFS in patients with urinary system cancer, and it is an effective biomarker of prognosis in patients with urologic cancer. PMID- 27710972 TI - Survival Outcomes in EGFR Mutation-Positive Lung Cancer Patients Treated with Gefitinib until or beyond Progression. AB - BACKGROUND: Discontinuation of gefitinib treatment is often accompanied by a disease flare. Some studies have demonstrated a benefit of the use of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) beyond progression; however, long-term results of these investigations remain limited. PATIENTS AND METHODS: We observed 70 patients with EGFR-mutated (EGFR-M+) non small cell lung cancer (NSCLC) receiving single-agent gefitinib in a routine clinical setting; 56 patients were experiencing RECIST progression at the time of the analysis. RESULTS: There was a significant increase (p = 0.00001) in overall survival (OS) in patients continuing on gefitinib beyond progression (n = 21; median duration of continued gefitinib use: 4.2 months; median OS: not reached; expected OS: 29.7 months) as compared to those who stopped gefitinib treatment upon disease progression (n = 35; median OS: 14.0 months). The association between extended gefitinib use and improved OS remained true in multivariate Cox regression analysis (hazard ratio = 4.49, 95% confidence interval 1.25-16.09; p = 0.021). Patient selection bias constitutes an essential limitation of this clinical observational study, given that patients with a more favorable disease course and/or high initial tumor sensitivity to TKI treatment were more likely to be considered for prolonged gefitinib use. CONCLUSION: This study confirms that continued administration of gefitinib beyond progression is a viable treatment option for some patients with EGFR-M+ NSCLC, in particular those who cannot be rescued by novel EGFR mutation-specific inhibitors such as osimertinib. PMID- 27710973 TI - Management of Isolated Vaginal Metastasis in Squamous Cell Cervical Cancer: 23 Years' Experience at a Single Center. AB - AIM: The aim of this study was to investigate the treatment options and survival of cervical cancer (CC) patients who develop isolated vaginal metastasis (IVM), and to establish risk factors for IVM. PATIENTS AND METHODS: A total of 21 cases with IVM were evaluated retrospectively. In addition, 42 control patients diagnosed with CC without recurrence were matched. Tumor size, depth of stromal invasion (DOI), lymphovascular space invasion (LVSI), and size of vaginal and lymph node metastases were analyzed in accordance with the pathology reports. Patients who had IVM were investigated in terms of treatment options (chemotherapy (CT), radiotherapy (RT), or chemoradiotherapy (CRT)) and survival. RESULTS: After detection of IVM, the 1-, 3-, and 5-year survival rates were 57.1, 23.8, and 9.5%, respectively. The mean survival time after metastasis detection was 23.1 +/- 31.3 months. LVSI, DOI >= 1/2, hemoglobin < 12 g/dl, postmenopausal status, and tumor size >= 4 cm were independent risk factors for IVM. The 5-year survival rates were 30.0% for patients receiving RT, 17.1% for patients receiving CRT, and 0% for patients receiving CT. CONCLUSION: IVM typically develops within the first 2 years after the diagnosis of CC, and survival is generally poor. RT was the most effective treatment in patients with IVM. PMID- 27710974 TI - Increased Expression of the Receptor for Advanced Glycation End-Products (RAGE) Is Associated with Advanced Breast Cancer Stage. AB - BACKGROUND: The receptor for advanced glycation end-products (RAGE) is a multiligand transmembrane receptor that is overexpressed in various pathological conditions including cancers. However, the expression pattern of RAGE in breast cancer tumors is still not completely clear. METHODS: In this study, we investigated the expression levels of RAGE in 25 fresh-frozen breast cancer samples and corresponding noncancerous tissue samples collected from breast cancer patients, by real-time polymerase chain reaction (PCR). Additionally, we performed immunohistochemistry on breast cancer specimens. RESULTS: The results indicate a high expression of the RAGE-encoding gene in the cancerous tissues. RAGE expression at the mRNA and protein levels was statistically significantly up regulated in advanced-stage and triple-negative breast tumors and node-positive tissues compared with other tissues (p < 0.001). A significant association between RAGE expression and tumor size was observed (p = 0.029). CONCLUSIONS: Overexpression of RAGE in advanced-stage tumors may be a useful biomarker for diagnosis and the prediction of breast cancer progression. PMID- 27710975 TI - A Multicenter Feasibility Study of EBUS-TBNA for Potentially Operable Non-Small Cell Lung Cancer: The JMTO LC07-02 Study (UMIN000001280). AB - BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a standard procedure for the pathological evaluation of the mediastinal nodal (N2) status of lung cancer; however, its feasibility in potentially operable patients with suspicion of minimal N2 disease remains unestablished. PATIENTS AND METHODS: A prospective multicenter study was conducted to assess the feasibility of EBUS-TBNA in this setting. Patients with clinical stage IIIA-N2 non-small cell lung cancer (NSCLC) and mediastinal nodal enlargement on computed tomography (CT) were eligible; patients were ineligible when CT revealed bulky (> 3 cm in the long-axis diameter) N2 or multiple (>= 3) station N2. If EBUS-TBNA revealed negative results, surgical staging procedures were mandatory. RESULTS: Among 20 eligible patients, EBUS-TBNA provided pathological confirmation of N2 disease (true-positive) in 12 patients. Among 8 patients with negative results with EBUS-TBNA, 4 patients were pathologically diagnosed as having N2 disease with surgical staging procedures (false-negative), and 4 were finally diagnosed as having non-N2 disease with nodal dissection by thoracotomy (true-negative). As a result, the sensitivity of EBUS-TBNA for N2 evaluation (primary endpoint) was 75.0% (95% confidence interval 47.6-92.7%). No grade 3-5 adverse event were documented. CONCLUSION: EBUS-TBNA is potentially safe and useful in the pathological evaluation of N2 status even in potentially operable NSCLC patients with suspicion of minimal N2 disease on preoperative CT.

PMID- 27710977 TI - The Systemic Management of Advanced Melanoma in 2016. AB - Melanoma is a common type of skin cancer with a high propensity to metastasize. Tyrosine kinase inhibitors targeting the mitogen-activated protein kinase (MAPK) pathway and immune checkpoint blockade have recently revolutionized the management of unresectable and metastatic disease. However, acquired resistance and primary non-response to therapy require novel treatment strategies and combinations. The purpose of this review is to provide a brief and up-to-date overview on the clinical management and current trial landscape in melanoma. We summarize the most pertinent studies on BRAF/MEK inhibitors and blockade of cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1). Although most agents show robust antitumor efficacy as single agents, further improvements have been achieved by the combination of both approved and developing drugs. We discuss ongoing trials and evaluate future approaches that may provide additional efficacy with less toxicity. PMID- 27710978 TI - Efficacy and Long-Term Safety of Everolimus in Pancreatic Neuroendocrine Tumor Associated with Multiple Endocrine Neoplasia Type I: Case Report. AB - BACKGROUND: Approximately 10% of pancreatic neuroendocrine tumors (NET) are associated with familial syndromes, with the most common type being multiple endocrine neoplasia type 1 (MEN-1). However, the available evidence on how to treat NET comes from studies in sporadic NET. CASE REPORT: Here we report the case of a 51-year-old male patient with a metastatic MEN-1-associated pancreatic NET and hypercalcemia related to primary hyperparathyroidism and tumor-secreted parathyroid-related protein. The patient was treated with everolimus, and showed complete resolution of hypercalcemia and tumor control for 3 years when he presented with pulmonary cryptococcosis and disease progression. CONCLUSION: This case report describes the activity of everolimus in a patient with MEN-1 associated pancreatic NET, its efficacy in treating malignant hypercalcemia associated with NET and the risk of opportunistic infections with prolonged use of this agent. PMID- 27710979 TI - Targeting Both Tumor and Stroma Cells to Treat Melanoma: NIPAWILMA. PMID- 27710980 TI - Surgical Strategy and Facial Nerve Outcomes in Petrous Bone Cholesteatoma. AB - OBJECTIVE: To review the classification and management of petrous bone cholesteatomas (PBCs) at our center and the outcomes of facial nerve (FN) management in these lesions. METHODS: This was a retrospective study. The setting was a quaternary referral center for skull base pathology in Italy. A total of 200 patients with 201 PBCs were included in the study. All patients diagnosed radiologically with PBCs were classified according to the Sanna classification. All patients were surgically treated and followed up with radiology. The main outcome measures - classification of PBCs, the surgical approach used, disease control, and FN outcomes - were analyzed. RESULTS: Supralabyrinthine PBCs were the most common type with 92 cases (45.8%) followed by the massive PBCs with 72 cases (35.8%). Preservation of preoperative FN function was highest in the infralabyrinthine (72.2%) and infralabyrinthine-apical (73.3%) types. The transotic approach was used in 66 cases (32.8%) in this series. The modified transcochlear approach type A was applied in 55 cases (27.3%). Active management of the nerve (rerouting, anastomosis, or grafting) was required in 53 cases (26.4%). Postoperatively, of the 116 cases with FN House-Brackmann grade I and II, 107 cases (92.2%) retained the same grade or improved. Recurrence was seen in 7 cases (3.5%). The mean duration of follow-up was 6.3 years. CONCLUSIONS: Radical disease clearance must take precedence over hearing and FN preservation in PBCs. Active FN management, including rerouting, end-to-end anastomosis, and cable nerve grafting, routinely come to play in the surgical management of PBCs, and the postoperative FN results after such interventions can be satisfactory in most cases. PMID- 27710982 TI - Relationship between urinary incontinence symptoms and urodynamic findings using a validated Arabic questionnaire. AB - BACKGROUND: Urinary incontinence is common, particularly in women. Urodynamic studies (UDS) can accurately assess the condition. Less invasive objective measuring tools correlate with urodynamic findings, but the Arabic version of the Urogenital Distress Inventory-6 (UDI-6) questionnaire has not been previously correlated with UDS in Arabian patients. OBJECTIVE: To correlate the Arabic version of the UDI-6 with urodynamic findings in Arabian women with urinary incontinence. DESIGN: Prospective. SETTING: Tertiary referral urology clinic. PATIENTS AND METHODS: All female patients presenting with urinary incontinence between July 2013 to March 2014. Patients answered the Arabic UDI-6 questionnaire and underwent a history and clinical examination, urine culture and UDS. MAIN OUTCOME MEASURES: Correlation between Arabic UDI-6 questionnaire score and urodynamic diagnosis. RESULTS: Eighty-seven women with a mean age of 57 (range, 22-72) years completed the UDI-6 and underwent UDS. The questionnaire revealed that 20 (23%) patients had urge incontinence, 28 (32%) had stress incontinence and 39 (45%) had mixed incontinence. As diagnosed by UDS, 26 (30%) had urge incontinence, 37 (42%) had stress incontinence, 16 (18%) had mixed incontinence and 8 (9%) had no abnormality. Eighty-six percent of patients (24/28) with pure stress urinary incontinence (SUI) symptoms had a positive UDS, and 55% (11/20) of patients with pure urge incontinence symptoms had a positive UDS. Of all patients with positiveresponse to the question for SUI, 53/67, 79% had positive UDS diagnosis with a correlation coefficient of 0.65 (P < .01). Of all patients with positive responses for urge incontinence, 27/59, 45.8% had positive UDS diagnosis with a moderate correlation coefficient of 0.38 (P < .01). CONCLUSIONS: The validated Arabic UDI-6 correlates significantly with UDS findings in Arabian women, particularly in women with SUI. LIMITATIONS: The sample size was relatively small, which prevented sub-analyses. Patient comorbidities were not evaluated. PMID- 27710981 TI - Clinical Practice Guidelines on the Screening and Treatment of Precancerous Lesions for Cervical Cancer Prevention in Saudi Arabia. AB - BACKGROUND: Cervical cancer is the third most common gynecological malignancy in Saudi women with an estimated incidence rate of 1.9 cases per 100 000 women years. More than 40% of cervical cancer cases are diagnosed at advanced stages due to lack of a routine screening program in Saudi Arabia. Thus, national guidelines for routine screening and treatment of precancerous cervical lesions are needed. METHODS: The Saudi Centre for Evidence-Based Healthcare invited a panel of local experts and partnered them with a team from McMaster University in Canada for methodological support, to develop national clinical practice guidelines on the screening and treatment of precancerous lesions for cervical cancer. After the panel identified key clinical questions, the McMaster University working group updated existing systematic reviews that had been used for the 2013 WHO Guidelines for screening and treatment of precancerous lesions for cervical cancer prevention. Recommendations were based on the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach. Those recommendations took into account the available evidence, patient values and preferences, and resource use in the Saudi context. The panel provided recommendations on two major issues: screening for precancerous lesions (cervical intraepithelial neoplasia 2 & 3) and treatment of those lesions to prevent cervical cancer in women who tested positive after screening. CONCLUSIONS: The Saudi expert panel recommends using the HPV DNA test followed by colposcopy or cytology (Pap test) followed by colposcopy to screen for CIN2+ in women at risk of cervical cancer. The panel recommends cryotherapy or loop excision electrosurgery procedure (LEEP) over cold knife cone biopsy to treat women at risk of cervical cancer that tests positive for CIN2+. Universal screening for precancerous cervical dysplasia in women in Saudi Arabia is recommended using HPV testing and or cytology. Either cryotherapy or LEEP are preferred for treatment. LIMITATIONS: National studies on cervical cancer screening modalities and treatment of precancerous cervical lesions, including HPV prevalence and its association with cervical cancer, are scarce. PMID- 27710983 TI - Vitamin D content in fortified low fat milk in Saudi Arabia. AB - BACKGROUND: Vitamin D deficiency is common in many countries, including Saudi Arabia. Various population-level preventive measures have been implemented, including milk fortification with vitamin D. OBJECTIVES: The main objective of the study was to determine vitamin D levels in fortified low fat cow milk on the Saudi Arabian market and to compare it with the label claims. DESIGN: Cross sectional study. SETTING: Academic research center. MATERIALS AND METHODS: Five milk batches from five major producers were purchased in five replicates from five major retail stores in Riyadh, Saudi Arabia. We used a validated liquid chromatography assay to measure vitamin D levels. All samples were producer labeled to contain 400 IU/L (10 ng/mL) vitamin D and were analyzed within the first 40% of their validity period. Intra-batch, inter-batch, and inter-producer variations were determined as a coefficient of variation. MAIN OUTCOME MEASURES: Intra-batch, inter-batch and inter-producer variations in vitamin D level. RESULTS: Overall, mean (SD) measured vitamin D level was 10.2 (1.6) with a range of 7.1-13.9 ng/mL. In 25 of 125 samples (20%), the vitamin D level was outside +/ 20% of the label claim (10.4% under-fortified, 9.6% over fortified). Intra batch, inter-batch, and intra-producer variations were 1.6 -20.8%, 8.2-20.8%, and 16.1%, respectively. CONCLUSIONS: Vitamin D content in fortified low fat cow milk on the Riyadh market matches label claim in 85% of the samples of major retailers. Variations from label claim in 15% of the samples are small and may not be clinically important. LIMITATIONS: This study was limited to five major retailers in the Riyadh area and did not examine full-fat or non-fat milk samples. PMID- 27710984 TI - The effect of parturient height on the median effective dose of intrathecally administered ropivacaine. AB - BACKGROUND: Pain during cesarean delivery is one of the more common reasons for a successful medicolegal claim. However, creating an extensive block area can result in hypotension, so determining the precise dose of local anesthetic is critical. OBJECTIVES: Investigate effects of parturient height on the median effective dose (ED50) of intrathecally-administered ropivacaine. DESIGN: Prospective cross-sectional analytic study. SETTING: Anesthesiology department in a provinicial hospital in China. METHODS: Parturients undergoing cesarean delivery under combined spinal and epidural anesthesia were stratified according to height as follows: 150 cm to 155 cm, 156 cm to 160 cm, 161 cm to 165 cm and 166 cm to 170 cm. The spinal component of the anesthetic was established by bolus administration of up-and-down doses of 0.75% plain ropivacaine as determined by the Dixon method. The initial dose of ropivacaine was 5.79 mg and the testing interval dose change was set at 0.75 mg. The block height for the first cold feeling at T5 was considered satisfactory anesthesia. MAIN OUTCOME MEASURES: ED50 values and vasopressor requirements, nausea, vomiting and shivering. RESULTS: In 120 parturients, the ED50 for satisfactory block height using intrathecal ropivacaine was 5.92 mg (95% confidence interval[CI] 5.02-6.86 mg) patients of 150 to 155 cm in height; 6.52 mg (95% CI 5.45-7.65 mg) in 156 cm to 160 cm; 7.49 mg (95%CI 6.83-8.25 mg) in 161 cm to 165 cm; 8.35 mg (95%CI 7.55-9.23 mg) in 166 to 170 cm. The ED50 of ropivacaine increased with increasing height of the subject. There were no significant differences in incidence of hypotension, vasopressor requirements, nausea, vomiting and shivering. CONCLUSION: The ED50 of intrathecal ropivacaine using sensitivity to cold sensation increased with parturient height, indicating that dose may be determined in part by height. LIMITATION: The ED95 rather than the ED50 for spinal anesthesia is more useful clinically. We did not control for the effect of weight on the dose of local anesthetic. Factors such as baricity, volume, concentration injected, temperature of the solution, and viscosity can affect intrathecal spread of the local anesthetics and block quality. PMID- 27710985 TI - Fasting plasma glucose levels and coronary artery calcification in subjects with impaired fasting glucose. AB - BACKGROUND: Prediabetes is associated with an increased risk of cardiovascular disease (CVD). While the association of impaired glucose tolerance with CVD has been shown in many studies, the relationship between impaired fasting glucose (IFG) and CVD remains unclear. OBJECTIVES: The purpose of this study was to compare the coronary artery calcium (CAC) scores of participants with normal fasting glucose versus those with IFG, according to fasting plasma glucose (FPG) levels, and to assess whether differences in CAC scores were independent of important confounders. DESIGN: Retrospective study. SETTING: Health Promotion Center of the University Hospital (Gyeonggi-do, South Korea), during the period 2010-2014. PATIENTS AND METHODS: Participants were enrolled from the general population who visited for a medical check-up. CAC was assessed in asymptomatic individuals by multidetector computed tomography. Anthropometric parameters and metabolic profiles were also recorded. Subjects were divided into four fasting glucose groups. Participants with a history of CVD or diabetes mellitus were excluded. MAIN OUTCOME MEASURES: Correlation between FPG and CAC scores, CAC score categories, and association between CAC score and FPG categories. RESULTS: Of 1112 participants, 346 (34.2%) had a CAC score > 0. FPG values in the IFG patients were positively but weakly correlated with CAC scores (r=0.099, P=.001). The incidence of CAC differed according to FPG level (P < .001) and in Kruskal Wallis test the mean CAC score differed by FPG group (P < .001). After adjustment for other factors in a multiple logistic regression analysis, those subjects with FPG >=110 mg/dL had a significantly higher risk of CAC than did subjects with normal fasting glucose (110. PMID- 27710987 TI - Prevalence and factors associated with geriatric malnutrition in an outpatient clinic of a teaching hospital in Jeddah, Saudi Arabia. AB - BACKGROUND: Malnutrition is highly prevalent among the elderly and is associated with poor clinical prognosis, decreased functional status, and increased morbidity and mortality. OBJECTIVE: To estimate the prevalence of geriatric malnutrition among outpatients of a geriatric clinic and to determine factors associated with malnutrition. DESIGN: Cross-sectional study. SETTING: Geriatric outpatient clinic of the King Abdul Aziz University Hospital, Jeddah. PATIENTS AND METHODS: All patients older than 60 years of age who attended the clinic during January 2016 were eligible for inclusion. Nutritional status was assessed using anthropometric data and by hemoglobin and albumin levels and lymphocyte count. The MNA was used to define malnutrition. MAIN OUTCOME MEASURES: Anthropometric measures, biochemical tests, and the scores on the short version of the Mini Nutritional Assessment (MNA). RESULTS: According to the MNA results, 8 (5.3%) of 152 elderly patients suffered overt malnutrition and 50 (32.9%) were at risk of malnutrition (71 males and 41 females; aged 72.4 [8.6] years). The prevalence of malnutrition was significantly higher among females (44.6%; 95% CI, 1.01-4.08; P=.044) than in males (28.3%). Malnourished patients were older than patients with normal nutritional status (mean 72.4 [8.6] years), and more common in patients who lived alone (62.5%). The malnourished patients had significantly smaller calf circumferences (63.4; 95% CI, 1.51-3.20; P=.001), and lower albumin and hemoglobin levels (P=.001). A significantly higher percentage of the malnourished patients compared with normal patients had experienced weight loss (37.9%; P < .001) and decreased food intake (56.9%; P < .001) during the previous three months. Binary logistic regression revealed that being female and living alone were significant predictors for being categorized as malnourished or at risk of malnutrition. CONCLUSION: The prevalence of malnutrition is high among geriatric outpatients. Routine screening for malnutrition among geriatric patients would allow early diagnosis and prompt intervention. LIMITATIONS: The heterogeneity of the study group (different diseases at different stages) could influence the generalizability of our findings. The relatively small number of patients (P=.002) is a potential limitation. PMID- 27710986 TI - The epidemiology of pituitary adenomas in a community-based hospital: a retrospective single center study in Saudi Arabia. AB - BACKGROUND: Data on pituitary adenoma (PA) prevalence in Saudi Arabia are scarce. OBJECTIVE: To estimate the epidemiology of PA in a well-defined population. DESIGN: Retrospective analysis. SETTING: Departments of Endocrinology and Radiology at King Fahad Armed Forces Hospital, Jeddah, Saudi Arabia. PATIENTS AND METHODS: Radiological and hormonal data of patients with pituitary adenoma by MRI were reviewed for the period January 2008 to December 2015. MAIN OUTCOME MEASURES: Prevalence of PA and hormonal abnormalities. RESULTS: Of 537 patients; 249 subjects (46.4%), 70 (28.1%) males and 179 (71.9%) females, were diagnosed to have PA with mean age 36.3 (14.1) years. Microadenoma and macroadenoma were seen in 171 (69%) and 78 (31%) subjects, respectively. Microadenomas were more prevalent than macroadenomas (68.7% vs. 31.3%). Microadenomas were significantly more prevalent in females, 131 (73.2 %) vs. 40 (57.1%) whereas macroadenomas were significantly more prevalent in males, 30 (42.9%) vs. 48 (26.8%) (P < .001 for both comparisons). Patients with microadenomas were significantly younger than patients with macroadenomas (P < .0001). Advanced age was significantly associated with a larger PA size (r=0.39, P < .0002). Three types of hyperfunctioning PA were seen: prolactinoma, somatotroph adenoma, and corticotroph adenoma. Five types of hypofunctioning PA were seen: panhypopituitarism, secondary hypogonadism, growth hormone deficiency, central hypothroidism and central adrenal insufficiency. Non-functioning PA were within normal laboratory hormonal values in 2% of cases. CONCLUSION: Our study showed that the prevalence of PA was greater than previously reported. This increased prevalence may have important implications when prioritizing funding for research and treatment of PA. LIMITATIONS: Clustering of cases within the study region might have affected estimates and limited study sample size. PMID- 27710988 TI - Outcome of loop versus divided colostomy in the management of anorectal malformations. AB - BACKGROUND: Colostomy is a common part of the management of high anorectal malformation (ARM) in the pediatric population. OBJECTIVE: To evaluate whether the type of colostomy (loop vs divided) has an impact on outcome in patients with ARM. DESIGN: A retrospective study. SETTING: King Faisal Specialist Hospital and Research Center, a tertiary care center. PATIENTS AND METHODS: All patients who were managed with colostomy for ARM and had definitive repair during the period of January 2000 to December 2014. Outcomes relative to the type of the colostomy were compared. MAIN OUTCOME MEASURES: Morbidities associated with each type of colostomy. RESULTS: There were 104 patients managed for ARM with colostomy as staged procedures, 63 males and 41 females. Patients had a colostomy at a median age of 6 days and were closed at a median of 11 months. Definitive repair was at a median age of 17 months. Type of fistula was 8 perineal, 21 rectovestibular, 35 rectourethral, 11 rectovesical and there were 16 without fistula and 13 cloaca anomalies. There were 55 loop and 49 divided colostomies. There were 91 descending/sigmoid and 13 transverse colostomies. Operative time for loop colostomy closure was shorter than with divided colo6stomy (76 minutes vs 94 minutes, P=.002). Three patients among the divided group had reversed orientation of the colostomy that had affected bowel preparations negatively prior to its repair. There was no differences in complications of creation and closure of loop and divided colostomies except in occurrence of skin excoriation. There was more skin excoriation with divided colostomy compared to loop colostomy (17 vs 10, P=.04). CONCLUSIONS: Loop colostomy has a shorter closure operative time and relatively fewer complications compared to the divided colostomy. Our data suggests that loop colostomy may be more favorable than divided colostomy for ARM patients. LIMITATIONS: Retrospective nature of the study and some colostomies performed at other hospitals. PMID- 27710989 TI - The impact of renal angiomyolipoma on estimated glomerular filtration rate in patients with tuberous sclerosis complex. AB - BACKGROUND: There is a growing concern that renal impairment may develop in patients with renal angiomyolipomas (AMLs) associated with tuberous sclerosis complex (TSC) as a consequence of the disease itself and/or the interventions to mitigate the risk of hemorrhage. OBJECTIVE: To assess the estimated glomerular filtration rate (eGFR) in patients with bilateral renal AMLs and the impact of tumor burden and intervention on renal function. DESIGN: Retrospective study. SETTING: Urology department of a tertiary care hospital. PATIENTS AND METHODS: All adult patients (>=18 years of age) with TSC-associated renal AMLs seen from October 1998 to June 2015. We included only patients with bilateral tumors or solitary kidneys at the last follow-up. MAIN OUTCOME MEASURES: The eGFR, renal volume, and number and type of interventions. RESULTS: We identified 12 patients (median age 27.6, interquartile range 23.7-39.9 years), a median follow-up period of 1266 days (33-3133), and a median renal size of 454.7 mL (interquartile range 344.7-1016.9 on the right side; 558.1 mL, interquartile range 253.7-1001.4 on the left). In 11 (91.7%) patients, the eGFR was > 60 mL/min/1.77 m2. Six patients had three total nephrectomies, one had a contralateral partial nephrectomy, and seven had selective arterial embolizations. Intervention was associated with a significantly reduced eGFR. The renal size did not correlate with the eGFR. CONCLUSIONS: TSC-associated renal AMLs may attain a large size but normal renal function is maintained in 92% of patients. Interventions to mitigate the risk of hemorrhage are associated with decreased renal function. LIMITATIONS: The renal size was used as a surrogate for tumor size. Other limitations were the limited number of patients and lack of split renal function testing. PMID- 27710991 TI - Identification of gout in unusual sites by dual energy computed tomography.

AB - : Polycythemia vera is a Philadelphia chromosome-negative myeloproliferative neoplasm. Chronic lymphocytic leukemia is a monoclonal expansion of a CD5+ CD19+ B lymphocytes. Chronic myeloproliferative neoplasms may coexist with indolent B cell malignant lymphomas of various types. The association of chronic lymphocytic leukemia with polycythemia vera is a rare event with only a few cases of coexistence ever reported. We report a 56-year-old man in whom these two disorders were diagnosed concomitantly. Possible etiopathogenic relationships between both disorders are discussed in this case report.

PMID- 27710993 TI - Interdisciplinary Feeding Team: A Medical, Motor, Behavioral Approach to Complex Pediatric Feeding Problems. AB - Pediatric feeding difficulties are complex and multifactorial in nature. Children who need assessment and individualized treatment for complex feeding problems are best served by an interdisciplinary treatment team. The medical, motor, and behavioral approach to treating pediatric feeding problems is presented as an avenue to treatment. By necessity, this approach requires a well-functioning interdisciplinary team, including nurses, physicians, registered dietitians, and feeding therapists (speech-language pathologists, occupational and physical therapists). We describe a robust interdisciplinary feeding team that applies a medical, motor, and behavioral approach to treating pediatric feeding problems. Within this team, pediatric gastroenterology nurse practitioners, dietitians, and speech pathologists function as integral members of the team. Description of each team member's expertise is provided and how they operate to support children with feeding problems and their families.

AB - PURPOSE: To enhance responsive feeding, this study aimed to characterize the development of feeding cues during infancy and toddlerhood. STUDY DESIGN AND METHODS: A secondary analysis was performed on a dataset of first-time, low income African American mother-infant pairs assessed at infant age 3, 6, 9, 12, and 18 months. A subsample with the 15 highest, middle, and lowest infant body mass index (BMI) Z-scores at 18 months was selected (n = 45). Using video recorded home feedings, early, active, and late receptiveness and fullness cues were assessed using the Responsiveness to Child Feeding Cues Scale at each time point. Descriptive statistics were used to characterize development. RESULTS: Early receptiveness cues were relatively rare over time, whereas active receptiveness cues were much more common. However, there were changes over time. For example, settling into the feeding decreased from ~50% at 3 and 6 months to 4.8% by 18 months, whereas postural attention and reaching for food increased after 6 months. In the first 6 months, falling asleep and decreasing muscle tone and activity level were the most common early fullness cues. Thereafter, taking interest in surroundings was most prevalent. Active fullness cues became increasingly diverse after 6 months, led by more assertive cues such as pushing or pulling away and communicating "no" verbally or nonverbally. CLINICAL IMPLICATIONS: These findings provide an empirical description of waxing and waning in feeding cues and indicate increasing intentionality of cues over the first 18 months of life. Knowing common cues across development may aid clinicians in enhancing parental feeding responsiveness, avoiding overfeeding, thereby decreasing risk of early childhood obesity.

AB - PURPOSE: We describe a patient with an unusually posterior varix of a vortex vein ampulla. METHODS: Case report. RESULTS: An unusually posterior varix of a vortex vein ampulla mimicking a choroidal neoplasm was identified. The diagnosis was obscured by the presence of overlying drusen. Through a combination of indocyanine green angiography and enhanced depth imaging optical coherence tomography, the varix was identified as an engorged vascular process correlating to ophthalmoscopic and tomographic examination. Collapse of the varix after direct digital pressure on the globe was observed on enhanced depth imaging optical coherence tomography further confirming our diagnosis. CONCLUSION: Varices of vortex vein ampullas may be incorrectly diagnosed as choroidal neoplasms. Using a combination of multimodal imaging and dynamic maneuvering, varices can be correctly identified. PMID- 27711004 TI - UNUSUAL CASE OF STELLATE NONHEREDITARY IDIOPATHIC FOVEOMACULAR RETINOSCHISIS. AB - PURPOSE: To report a case of unilateral stellate nonhereditary idiopathic foveomacular retinoschisis (SNIFR) in a young male showing structural changes induced by a Valsalva maneuver. METHODS: Case report of a 26-year-old oboist with SNIFR, including multimodal imaging. Eye-tracked spectral-domain optical coherence tomography (SD-OCT) was used to compare the retinal architecture at rest and during a Valsalva maneuver. RESULTS: Spectral-domain optical coherence tomography showed macular and peripapillary retinoschisis with no signs of pathologic myopia, optic pit, or vitreoretinal traction. A full-field electroretinogram showed supranormal responses in the eye studied. Magnetic resonance imaging of the brain showed no abnormalities. Eye-tracked SD-OCT scans showed an increase in retinal thickness reaching 28 microns superior to the disc during an induced Valsalva maneuver. CONCLUSION: Stellate nonhereditary idiopathic foveomacular retinoschisis is a diagnosis made when other known causes of retinoschisis have been excluded. In this patient with unilateral SNIFR, an increase in retinal thickness during a Valsalva maneuver was demonstrated. Further study would be needed to determine the mechanism producing this change and to assess its potential influence on visual prognosis. PMID- 27711006 TI - Liver transplantation 2007: where do we go from here? PMID- 27711007 TI - Current status of liver transplantation for hilar cholangiocarcinoma. AB - PURPOSE OF REVIEW: Liver transplantation for unresectable hilar cholangiocarcinoma is a highly controversial issue. This review will summarize results with transplantation alone and a new strategy of high-dose neoadjuvant chemoradiotherapy and subsequent liver transplantation. The review will address controversies regarding this novel approach to the treatment of hilar cholangiocarcinoma, including prioritization of patients with cholangiocarcinoma awaiting scarce deceased donor livers. RECENT FINDINGS: Results with liver transplantation alone for patients with unresectable cholangiocarcinoma are poor and do not justify use of scarce donor livers for these patients. Several centers have recently reported excellent results combining high-dose neoadjuvant chemoradiotherapy and liver transplantation for patients with early stage disease. Patient selection, operative staging, timely transplantation, and strict adherence to protocol are keys to success. SUMMARY: Hilar cholangiocarcinoma - once a contraindication for transplantation - has reemerged as an indication for transplantation when combined with neoadjuvant therapy. Results are comparable to results achieved with liver transplantation for other indications and exceed results with standard resection. PMID- 27711008 TI - Donation after cardiac death and liver transplantation. AB - PURPOSE OF REVIEW: This review discusses recent results and analyses on the use of donation after cardiac death (DCD) allografts in liver transplantation, including outcomes based on donor and recipient risk stratification, as well as associated postoperative complication rates. RECENT FINDINGS: Outcomes from the use of DCD donors can be improved with selective and appropriate donor-recipient pairings, although the optimum combination remains undetermined. Older DCD donors can be utilized, and arguments are presented for withdrawal of life support processes in the intensive care unit rather than in the operating room. SUMMARY: Increasing the donor pool for liver transplantation is required to prevent many of the deaths that occur while the patient is on the wait list. Under specific conditions, many studies report positive outcomes from of the use of DCD donors for liver transplantation. PMID- 27711009 TI - Machine perfusion preservation of the liver: a worthwhile clinical activity? AB - PURPOSE OF REVIEW: Although successful machine perfusion procedures of the liver were first performed almost four decades ago, technical and logistical constraints have prevented general acceptance. Interest in the procedure has recently been renewed due to its potential to resuscitate marginal organs. This review describes experimental and clinical liver hypothermic machine perfusion studies and current developments. RECENT FINDINGS: Experimental studies have shown that oxygenated hypothermic machine perfusion provides a complete washout and can restore parenchymal energy status, a phenomenon of particular importance in preservation of livers from compromised donors. Additionally, perfusion of the hepatic artery can prevent ischemic-type biliary lesions. Short-term and continuous hypothermic machine perfusion prior to or after cold storage preservation have proven more effective than cold storage alone. SUMMARY: The benefits of hypothermic machine perfusion for both heart-beating and nonheart beating liver grafts seem promising in terms of expanding the donor pool. As liver hypothermic machine perfusion systems are not yet commercially available, the process is currently only clinically used for kidney grafts. Clinical application appears feasible in the near future as new, easy-to-use systems and solutions are currently under development. PMID- 27711010 TI - Transmission of viral disease to the recipient through the donor liver. AB - PURPOSE OF REVIEW: Morbidity and mortality after liver transplantation continue to be significantly influenced by infectious complications. A particular concern is transmission of pathogens through the graft, which may cause significant disease in the recipient. RECENT FINDINGS: For frequently transmitted herpes viruses with high seroprevalence such as cytomegalovirus, Epstein-Barr virus and human herpes viruses 6 and 7, significance, diagnosis, spectrum of disease in the recipient, prophylaxis and therapy are well established. Less is known about rare viruses such as West Nile virus, rabies virus, human choriomeningitis virus, human herpes virus 8 and human T-cell lymphoma 1, which are in many cases fatal. A plenitude of other viruses that potentially can be transmitted with a donor liver may exist, for which no detailed information is currently available. Grafts from anti-hepatitis B virus core antibody positive donors can be safely used when using lamivudine/hepatitis B immunoglobulin prophylaxis; hepatitis C virus positive organs should be given to hepatitis C virus positive individuals only. SUMMARY: With the utilization of increasingly extended criteria donors, the risk for transmission of viruses with the graft may become a more common complication. These viruses will include rare and new pathogens and testing donors for these viruses may become necessary. PMID- 27711011 TI - The role of antibody induction in liver transplantation. AB - PURPOSE: Antilymphocyte antibody induction has been used in liver transplantation for decades, initially as part of a triple or quadruple immunosuppressive protocol to prevent rejection or in the treatment of steroid-resistant rejection. More recently there has been renewed interest in antibody induction in liver transplantation as part of a strategy to eliminate or reduce one or more immunosuppressive agents. This review highlights recent advances in the role of antibody induction in liver transplantation. RECENT FINDINGS: Primary interest in antibody induction now falls into four major categories: steroid avoidance; calcineurin inhibitor reduction as a renal sparing protocol; minimal immunosuppression protocols (tolerance); and limiting hepatitis C recurrence. These protocols usually involve short courses of antibody induction in the peritransplant period, with decreased reliance on other agents after transplantation. Recent reports demonstrate several beneficial effects of antibody induction and suggest that, in the Model for End-Stage Liver Disease era, antibody induction in immunosuppressive strategies in liver transplantation will become increasingly important. SUMMARY: Antibody induction in liver transplantation confers valuable benefit in limiting the adverse effects of maintenance immunosuppression. Antibodies allow the subsequent reduction or elimination of other agents to minimize overall immunosuppression. PMID- 27711013 TI - Intestinal transplantation: an underused transplant procedure. PMID- 27711012 TI - Liver-kidney transplantation in the Model for Endstage Liver Disease era: is it overdone? AB - PURPOSE OF REVIEW: Simultaneous liver-kidney transplantation is increasing. This stimulates concern about unnecessary kidney transplantation (for acute kidney failure, hepatorenal syndrome) in liver transplant candidates. RECENT FINDINGS: Liver transplants are allocated by the Model for Endstage Liver Disease (MELD) score - a number heavily weighted by the serum creatinine. The serum creatinine value varies depending upon the laboratory where it is measured, is different between genders without a correction factor in MELD and is generally inaccurate as a marker of kidney function in liver failure. Criteria for dual transplantation vary between programs and there is no official oversight of the practice. Up to 6.5% of simultaneous transplant candidates on dialysis at listing discontinue dialysis before transplant. Furthermore, simultaneous liver-kidney transplant compared with liver transplant alone improves survival only for those liver candidates on dialysis at transplant. SUMMARY: It is time to review the allocation of kidney allografts to liver transplant candidates to avoid inappropriate transplantation. More complete investigation of kidney function following simultaneous liver-kidney transplantation is needed, in addition to improved methods to determine the recoverability of renal dysfunction in liver transplant candidates. Before an optimal algorithm is possible, however, basic and clinical investigation will be needed. PMID- 27711014 TI - Home parenteral nutrition in adults. AB - PURPOSE OF REVIEW: This review summarizes the latest epidemiologic data, and indications and methods for preventing complications from home parenteral nutrition (HPN), and it discusss survival, prognosis and quality of life of HPN patients who are potential candidates for intestinal transplantation. RECENT FINDINGS: Although alteration in hepatic enzymes is frequent with HPN, severe HPN related liver disorders are rare because of improvements in nutritional support. In experienced centres, likelihood of survival in HPN patients may reach 86% and 71% at 1 and 10 years, respectively. About 15% of adult HPN patients are potential candidates for intestinal transplantation. SUMMARY: Complications include catheter-related sepsis and thrombosis, metabolic disorders, nutritional deficiency, psychological alteration and rehabilitation problems. Recent studies found that catheters lasted for 1.5 years on average. Alteration in hepatic enzymes alterations is frequent but severe liver complications are rare. Bone alterations occur in 75% of HPN patients, with multifactorial aetiology. Lipid administration should not exceed 1 g/kg per day. Overall probability of survival is good at 1 and 10 years; 10% of deaths are due to HPN complications. A large survey in European centres revealed that 15% of adults and 34% of children are candidates for intestinal transplantation. PMID- 27711015 TI - Is there a role for 'acute' or 'preemptive' intestinal transplantation? AB - PURPOSE OF REVIEW: 'Preemptive' transplantation is performed before underlying disease becomes advanced, compromising transplant feasibilities and posttransplant outcome while 'acute' transplant is performed when organ function is compromised and there is life-threatening risk. In intestinal transplantation an indication for transplant is failure of total parenteral nutrition in patients with intestinal insufficiency: liver disease associated with intestinal failure has a primary role in choosing the type of transplant to be performed and in establishing timing of transplantation. RECENT FINDINGS: Development of hepatic dysfunction represents an indication for preemptive intestinal transplantation at less than 1 year of parenteral nutrition. Regression of intestinal-failure liver disease may be achieved by isolated intestinal transplantation without liver grafting when liver disease is reversible. Therefore an early or preemptive indication for intestinal transplantation, in selected cases, represents liver salvage therapy associated with increased survival. Indications for acute intestinal or multivisceral transplant are few and confined to emergency trauma involving liver/bowel integrity and function, but above all the need of retransplant for multivisceral transplant recipients. SUMMARY: A preemptive isolated intestinal transplantation is strongly advised when liver disease occurs (if reversible) while there are only few clinical indications for acute intestinal transplantation (unless a multivisceral retransplant is needed). PMID- 27711016 TI - Intestinal transplantation: current improvements and perspectives. AB - PURPOSE OF REVIEW: This review summarizes the most recent relevant knowledge in clinical practice in the field of intestinal transplantation. RECENT FINDINGS: Three important factors that have allowed improving results during the last few years are reviewed here. The first relates to the development of a different approach to tackle the underlying cause of intestinal failure and to the patient's characteristics in terms of liver function, age, and body size. The second involves immune modulation and especially the immunosuppressive regimen at induction. The third refers to posttransplantation monitoring, in particular the diagnosis and treatment of intestinal graft rejection and lymphoproliferative disorders. Patient status and referral for intestinal transplantation remain debated. The Intestinal Transplant Registry and a report from an individual program have demonstrated the relationship between a patient's pretransplant status and outcome. Candidacy for intestinal transplantation was analysed in a European survey of home parenteral nutrition patients. Early referral and listing are important for successful outcomes after intestinal grafting. SUMMARY: Patient management should include therapies adapted to each stage of intestinal failure based on a multidisciplinary approach in centers involving surgery, gastroenterology, parenteral nutrition expertise, home parenteral nutrition programs, and liver-intestinal transplantation experience. Timing for referral of patients in specialized centers remains a crucial issue. PMID- 27711017 TI - Advances in anesthesia and organ transplantation: pearls of wisdom from the pioneers. PMID- 27711018 TI - Liver transplantation and pulmonary hypertension: pathophysiology and management strategies. AB - PURPOSE OF REVIEW: Increases in pulmonary artery pressure are seen in 20% of patients with liver cirrhosis due to a high cardiac output state together with circulatory volume overload. Some patients develop true pulmonary arterial hypertension with pathological changes in the pulmonary vasculature, an elevated pulmonary vascular resistance, and an increased transpulmonary gradient. Survival of patients with portopulmonary hypertension is poor once it becomes moderate to severe, whether or not liver transplant is undertaken. This increase in mortality is the result of right heart dysfunction. RECENT FINDINGS: Screening for portopulmonary hypertension occurs in most transplant centers using Doppler echocardiography to determine the right ventricular systolic pressure. The role of right heart function has been identified as a significant component in the survival of the new graft and the recipient during orthotopic liver transplant. SUMMARY: Our understanding of the management of patients with portopulmonary hypertension and the role of liver transplantation is improving as the results of multicenter databases are analyzed. Single center series are reaching a reasonable size, adding to our knowledge base, and helping in the development of evidence-based practice guidelines. The importance of right heart function and the use of perioperative echocardiography are better defined in the management of orthotopic liver transplant. PMID- 27711019 TI - Fluid therapy in organ transplantation. AB - PURPOSE OF REVIEW: Fluid management remains a controversial subject in perioperative medicine and organ transplantation. Various case series, anecdotes and tradition guide many fluid choices, especially when good evidence is lacking. Recent advances in the understanding of pharmacokinetic and pharmodynamic profiles of fluids, as well as transplantation physiology and pathophysiology, can guide us in new approaches to common problems. RECENT FINDINGS: This review is intended to describe some of the latest thinking on subjects like saline induced hyperchloraemic metabolic acidosis, the use of goal-directed approaches to volume resuscitation in perioperative medicine, the relative lack of evidence for low central venous pressure techniques in liver transplantation, some of the drug effects of intravenous fluids, as well as the complex issue of different crystalloids and colloids in renal transplantation. SUMMARY: Fluid therapy in transplant medicine is usually best practiced using goal-directed approaches and balanced electrolyte formulations when possible, even in renal failure. Some fluids may exert drug effects that could alter organ preservation and reperfusion, while the certain hydroxyethyl starches appear to be less toxic in renal transplantation than first suspected, especially when clinicians consider free water requirements in these settings. PMID- 27711020 TI - Liver transplantation and risk of bleeding. AB - PURPOSE OF REVIEW: Blood loss in orthotopic liver transplantation has declined during the past decade. Recent papers addressed this issue and emphasized its importance, because there is a significant correlation between intraoperative blood transfusion requirements and postoperative morbidity. This review addresses changes in practice that might have led to reduced blood loss. RECENT FINDINGS: Many preoperative variables that predict blood loss during orthotopic liver transplantation have been found. These vary between studies. Differences in perioperative blood loss, transfusion criteria and intraoperative management of coagulation may account for the interhospital variations in transfusion of red blood cells during orthotopic liver transplantation. Therefore, a risk index developed in one centre should not be applied without evaluation in other centres. Introduction of the piggyback technique and close monitoring of coagulation with thromboelastography have led to reduced blood transfusion requirements. Use of antifibrinolytics has shown to decrease blood loss. Recombinant factor VIIa is not indicated for treatment of coagulation abnormalities during orthotopic liver transplantation, and its use is justified only as rescue therapy. SUMMARY: Recent changes in blood conservation practices in orthotopic liver transplantation are presented and discussed. PMID- 27711021 TI - Impact of the Model for Endstage Liver Disease score on liver transplantation. AB - PURPOSE OF REVIEW: Allocation of deceased donor livers for transplantation is currently based on the Model for Endstage Liver Disease (MELD) score, which has fundamentally changed liver transplantation since its implementation in 2002. This review discusses the development, impact and problems associated with the system. RECENT FINDINGS: The MELD system was developed to provide a more objective means of prioritizing candidates for liver transplantation and to allocate livers based on greatest medical need. Liver allocation based on MELD score has had a remarkable effect, such as reducing waiting list mortality and increasing transplantation among patients with greater severity of illness, without a measurable decrement in postoperative survival. Unfortunately, potential problems have been identified. These include wide variation in illness severity in recipients; significant variation in MELD score depending on the clinical laboratory utilized to measure international normalized ratio; and a three-fold increase in the number of liver-kidney transplant recipients. SUMMARY: While MELD-based liver allocation has resulted in a marked improvement in liver allocation, there are still problems with the system. The challenge for the liver transplantation community is to prospectively evaluate the liver allocation system to ensure it remains the most effective and fair means of allocating deceased donor livers. PMID- 27711022 TI - Donation after cardiac death. AB - PURPOSE OF REVIEW: The present review will provide anesthesiologists with the scientific information and ethical arguments they need to make decisions about donation after cardiac death (DCD) for their clinical practices. RECENT FINDINGS: Organs derived from DCD benefit patients who would otherwise die without transplantation. The practice of DCD ties the withdrawal of life support to organ donation. The close approximation of cessation of circulation to the recovery of organs demands a systematically structured approach to ensure that patient care at the end of life will not be sacrificed for organ donation. In response, the medical community has developed standards of care through expert opinion and consensus. There is general agreement that patients are entitled to expert care at the end of life whether or not they will be organ donors. Thus, abrupt transfer of patient care to an anesthesiologist is usually not in the best interest of the patient. SUMMARY: By 2007, all US hospitals will have protocols for DCD. Anesthesiologists should review existing protocols and participate in the development of new ones to ensure that the approach to DCD conforms to current standards and that patients have a designated care provider for the withdrawal of life support.

PMID- 27711024 TI - Reference Intervals of Thromboelastometric Evaluation of Coagulation in Pediatric Patients with Congenital Heart Diseases: A Retrospective Investigation. AB - BACKGROUND Rotational thromboelastometry (ROTEM(r)) is a point-of-care test for coagulation, enabling physicians to make a swift decision. The aim of this investigation was to establish reference intervals of thromboelastometric evaluation for coagulation in pediatric patients with congenital heart diseases (CHD). MATERIAL AND METHODS As baseline data, 3 assays of ROTEM(r) (INTEM, EXTEM, and FIBTEM) were measured after anesthesia induction. ROTEM(r) parameters were clotting time (CT), amplitude at 10 min (A10), clot formation time (CFT), a angle, maximal clot firmness (MCF), clot lysis index at 60 min (LI60), and maximal clot elasticity (MCE). As age is a well-known factor for maturation, age groups were determined as follows; 1) <1 month, 2) 1-3 months, 3) 4-12 months, 4) 1-3 years, 5) 4-6 years, 6) 7-12 years, and 7) 13-16 years. Reference limits representing 95% of distribution of ROTEM(r) parameters and 90% confidence intervals of upper and lower reference limits were calculated. RESULTS The data of 413 patients were analyzed. Although INTEM CT was prolonged, significantly shorter CT and CFT, steeper alpha, and greater A10, MCF, and MCE were shown in patients age <3 months compared to older children. CONCLUSIONS Reference intervals of thromboelastometric evaluation for coagulation from pediatric patients with CHD were shown to have similar pattern to those obtained from healthy pediatric patients. Pediatric patients with CHD, even with cyanosis, were demonstrated to have functionally intact coagulation profile before surgery.

AB - Rheumatoid arthritis (RA) is a common chronic inflammatory disease affecting many tissues and resulting in substantial morbidity and increased mortality. Arthritis is the most notable clinical feature, but extra-articular features can have devastating consequences. Pulmonary manifestations are common in RA, with high rates of disease related lung disease and a propensity to pulmonary infections. Respiratory illness remains a leading cause of death among RA populations. Modern medicine greatly reduces the illness burden among patients with RA, particularly through the use of disease-modifying medications. Methotrexate is recommended as the first-line treatment of RA as it effectively reduces disease activity, morbidity and mortality. However, it has long been implicated as a causative agent in lung disease. The evidence for a cause and effect relationship in modern populations is contentious, but critically important. Increasing recognition of the importance and prevalence of interstitial lung disease in RA, and recent studies on the incidence of lung disease among RA and non-RA populations have cast doubt on the role of methotrexate as a causative agent. A correct understanding of the complex pulmonary disease processes in RA is crucial if we are to improve outcomes in this patient group. In this article we will discuss the epidemiology and characteristics of lung disease in rheumatoid arthritis and its possible relationship to methotrexate use. PMID- 27711026 TI - Preoperative functional assessment and optimization in surgical patient: changing the paradigm. AB - Functional capacity has been shown to be a major determinant of surgical outcome since it is related to postoperative complications, activity and daily function, level of independence and quality of life. Anesthesiologists as "perioperative physicians", can identify those scoring systems that assess functional capacity, whether from the basic physical history and walk test to the most complex such as cardiopulmonary exercise testing, and formulate intraoperative and postoperative interventions (rehabilitation) to minimize the impact of surgery on the recovery process. Nevertheless, the preoperative period can be used as an opportune time to increase functional reserve in anticipation of surgery, thus enabling the patient to better withstand the metabolic cost of surgical stress (prehabilitation). There is a compelling evidence that prehabilitation programs, including physical exercise, nutritional optimization and relaxation strategies, can enhance preoperative physiological reserve, however further studies are needed to identify the most appropriate protocols for those patients at risk, and assess the impact of such programs on clinically meaningful surgical outcomes. PMID- 27711027 TI - Quantification of the amount of dental material removed by selective grinding in wax dentures with photogrammetric measurements. AB - BACKGROUND: The use of photogrammetry may be a new method to quantify the amount of artificial dental material removed from the surface of each teeth during the grind procedure (SG). SG is necessary in each denture to reach a correct occlusion. It consists in a refine action on the prosthesis teeth's surface using milling machine tools, aimed to remove the interferences (pre-contacts) between upper and lower teeth during chewing. This measure is achieved after a comparison between pre and post-grinding 3D models. This new application could be of interest for both dentists and dental technicians because it could be used to evaluate, with a accurate numerical description, the action applied on teeth surfaces during the grinding process. Furthermore, results of the analysis could have some value for the dental industry, since the use of photogrammetry can improve the process, reducing costs during the design of artificial teeth and eventually this method could be used as a teaching tool both for dental and "dental technician" high school students. The purpose of this work is to measure the thickness of the artificial enamel removed during grinding phases. Usually, the dental technician adjusts the dental plate on the mount of the patient following the traditional method, without a quantitative evaluation of the material removed. The photogrammetric method (PM) proposed here allows to measure the amount of material removed during the grinding process. This measure is achieved after a comparison between pre and post-grinding 3D models. METHODS: Under control of three teachers (experts of dentures performed according to the Gerber method) ten complete dentures arrangements (upper and inferior arches) performed by dental students at the Prosthodontic Department of the University of Parma, Italy were analyzed with PM before and after SG. RESULTS: The average thickness variation between the pre and post-grinding dentures is within the range of 0.1/0.4 mm. For the upper arches, the mean value of the SG process is 223 um while for the inferior arches is 240 um. Results show that the most important grind process in all models appear in correspondence of cusps, with values up to 1660 um. On the other hand, in correspondence of the fossae the results show a moderate grind action: the value is around 200-300 um. Conversely to guidelines thought to students: cusps undergo a greater grinding process than fossae, consequently cusps should be revisioned at least on their technical and morphological aspects. The average thickness variation between the pre and post grinding dentures is within the range of 0.1/0.4 mm, this mean an equal value loss of vertical dimension. Furthermore, the knowledge of the gauge material removed during the SG could be useful for dental industries, giving important information, that could be considered for project and design of artificial teeth. CONCLUSIONS: The FM implemented in this article has given satisfactory preliminary results, showing good accuracy, low costs and high versatility. It is necessary to highlight that this is an experimental method and that the present analysis is a pilot study that needs further evaluation. Nevertheless results obtained could be of some value for medical companies, in order to improve the artificial teeth's design and project. Moreover, such a method may serve as educational tool for dental students. PMID- 27711028 TI - Platelet-rich fibrin: a boon in regenerative endodontics. AB - Research into regenerative dentistry has contributed momentum to the field of molecular biology. Periapical surgery aims at removing periapical pathology to achieve complete wound healing and regeneration of bone and periodontal tissue. Regenerative endodontic procedures are widely being added to the current armamentarium of pulp therapy procedures. The regenerative potential of platelets has been deliberated. Platelet-rich fibrin (PRF) is a wonderful tissue engineering product and has recently gained much popularity due its promising results in wound healing bone induction. The features of this product are an attribute of platelets which, after cellular interactions, release growth factors and have shown application in diverse disciplines of dentistry. This paper is intended to shed light onto the various prospects of PRF and to provide clinical insight into regenerative endodontic therapy. PMID- 27711029 TI - Adipose tissue, obesity and non-alcoholic fatty liver disease. AB - The association of obesity with non-alcoholic fatty liver disease (NAFLD) has been established. Obesity has been linked not only to initial stages of the disease, i.e., simple steatosis (SS), but also to its severity. From an epidemiologic point of view, both diseases has an increasing prevalence worldwide. From a pathogenetic point of view, obesity and its associate IR contribute to the initial fat accumulation in the hepatocyte (SS), but also to the progression of SS to nonalcoholic steatohepatitis (NASH), NASH-related cirrhosis and hepatocellular carcinoma (HCC). From a clinical point of view, obesity has increased morbidity and mortality when combined with NAFLD, owing to cardiovascular and liver-specific mortality, including higher HCC risk. From a therapeutic point of view, weight loss is regarded as the cornerstone for the disease prevention and treatment. Although diet and exercise are the first choice to this aim, they are both difficult to achieve and sustain. Thus, the need for pharmacological treatment is considered of high importance. To treat obesity through pharmacologic weight loss, orlistat has been investigated, though with limited efficacy. Currently, liraglutide appears to be more efficacious, but it has not been officially approved for specifically NASH patients. Bariatric surgery is another alternative for severely obese patients showing histological improvement in NASH patients. However, since relative data from randomized trials are very limited, morbid obesity-related NASH patients may be subjected to bariatric surgery only after a careful individualized risk-benefit assessment.

AB - INTRODUCTION: Surgical management of external rectal prolapse (ERP) remains a challenge with the breadth of choices available and varies on the international, national, regional and locoregional level. Significant innovation has led to new techniques to manage ERP including changes to both abdominal and perineal approaches. EVIDENCE ACQUISITION: A systematic, English-language search of major databases was conducted from 2006-2016. From 636 papers two reviewers identified 24 studies which compared two or more surgical techniques in adult patients with rectal prolapse and reported on complications, quality of life or recurrence. The Newcastle-Ottawa Scale (NOS) was used to score quality in non-randomized control trials (RCT) and the Cochrane Collaboration tool was use for RCTs. EVIDENCE SYNTHESIS: Abdominal and perianal surgeries both result in the resolution of symptoms and an improvement of quality of life for most patients. Short-term outcomes generally favored laparoscopy. Rectopexy with or without resection confers balances a low risk of recurrence with a similar complication rate to perineal surgery. The quality of included studies was general poor and most was at significant risk of bias. CONCLUSIONS: Most studies are of low quality and surgical management should be individualized to balance risk of the operation and the potential benefit to quality of life. Laparoscopy and modern anesthesia has made the abdominal approach more attractive even for elderly patients. PMID- 27711031 TI - State-Specific Prevalence of Current Cigarette Smoking and Smokeless Tobacco Use Among Adults - United States, 2014. AB - Tobacco use is the leading cause of preventable disease and death in the United States, resulting in approximately 480,000 premature deaths and more than $300 billion in direct health care expenditures and productivity losses each year (1). In recent years, cigarette smoking prevalence has declined in many states; however, there has been relatively little change in the prevalence of current smokeless tobacco use or concurrent use of cigarettes and smokeless tobacco in most states, and in some states prevalence has increased (2). CDC analyzed data from the 2014 Behavioral Risk Factor Surveillance System (BRFSS) to assess state specific prevalence estimates of current use of cigarettes, smokeless tobacco, and cigarette and/or smokeless tobacco (any cigarette/smokeless tobacco use) among U.S. adults. Current cigarette smoking ranged from 9.7% (Utah) to 26.7% (West Virginia); current smokeless tobacco use ranged from 1.4% (Hawaii) to 8.8% (Wyoming); current use of any cigarette and/or smokeless tobacco product ranged from 11.3% (Utah) to 32.2% (West Virginia). Disparities in tobacco use by sex and race/ethnicity were observed; any cigarette and/or smokeless tobacco use was higher among males than females in all 50 states. By race/ethnicity, non-Hispanic whites had the highest prevalence of any cigarette and/or smokeless tobacco use in eight states, followed by non-Hispanic other races in six states, non-Hispanic blacks in five states, and Hispanics in two states (p<0.05); the remaining states did not differ significantly by race/ethnicity. Evidence-based interventions, such as increasing tobacco prices, implementing comprehensive smoke-free policies, conducting mass media anti-tobacco use campaigns, and promoting accessible smoking cessation assistance, are important to reduce tobacco use and tobacco-related disease and death among U.S. adults, particularly among subpopulations with the highest use prevalence (3).

AB - Bullying among youths is defined as any unwanted aggressive behavior by another youth or group of youths who are not siblings or current dating partners and involves an observed or perceived power imbalance, and is repeated multiple times or is highly likely to be repeated (1). As a form of youth violence, bullying can include aggression that is physical (hitting or tripping), verbal (name calling or teasing), or relational/social (rumor spreading or leaving out of a group). Electronic aggression, or cyber-bullying, is bullying that occurs through the Internet, cellphone technology, and social media (e.g., e-mail, website, text messaging, posting videos, or pictures) (2). PMID- 27711033 TI - Update: Interim Guidance for Preconception Counseling and Prevention of Sexual Transmission of Zika Virus for Persons with Possible Zika Virus Exposure - United States, September 2016. AB - CDC has updated its interim guidance for persons with possible Zika virus exposure who are planning to conceive (1) and interim guidance to prevent transmission of Zika virus through sexual contact (2), now combined into a single document. Guidance for care for pregnant women with possible Zika virus exposure was previously published (3). Possible Zika virus exposure is defined as travel to or residence in an area of active Zika virus transmission (http://www.cdc.gov/zika/geo/index.html), or sex* without a condom? with a partner who traveled to or lived in an area of active transmission. Based on new though limited data, CDC now recommends that all men with possible Zika virus exposure who are considering attempting conception with their partner, regardless of symptom status,S wait to conceive until at least 6 months after symptom onset (if symptomatic) or last possible Zika virus exposure (if asymptomatic). Recommendations for women planning to conceive remain unchanged: women with possible Zika virus exposure are recommended to wait to conceive until at least 8 weeks after symptom onset (if symptomatic) or last possible Zika virus exposure (if asymptomatic). Couples with possible Zika virus exposure, who are not pregnant and do not plan to become pregnant, who want to minimize their risk for sexual transmission of Zika virus should use a condom or abstain from sex for the same periods for men and women described above. Women of reproductive age who have had or anticipate future Zika virus exposure who do not want to become pregnant should use the most effective contraceptive method that can be used correctly and consistently. These recommendations will be further updated when additional data become available. PMID- 27711034 TI - Real-Time Monitoring of Vaccination Campaign Performance Using Mobile Phones - Nepal, 2016. AB - In 2012, the Global Vaccine Action Plan* established a goal to achieve measles and rubella elimination in five of the six World Health Organization (WHO) regions (194 countries) by 2020 (1). Measles elimination strategies aim to achieve >=95% coverage with 2 routine doses of measles-containing vaccine (2), and implement supplementary immunization activities (SIAs)? in settings where routine coverage is low or where there are subpopulations at high risk. To ensure SIA quality and to achieve >=95% SIA coverage nationally, rapid convenience monitoring (RCM) is used during or immediately after SIAs (3,4). The objective of RCM is to find unvaccinated children and to identify reasons for nonvaccination in areas with persons at high risk, to enable immediate implementation of corrective actions (e.g., reassigning teams to poorly vaccinated areas, modifying the timing of vaccination, or conducting mop-up vaccination activities). This report describes pilot testing of RCM using mobile phones (RCM-MP) during the second phase of an SIA in Nepal in 2016. Use of RCM-MP resulted in 87% timeliness and 94% completeness of data reporting and found that, although 95% of children were vaccinated, 42% of areas required corrective vaccination activities. RCM-MP challenges included connecting to mobile networks, small phone screen size, and capturing Global Positioning System (GPS) coordinates. Nonetheless, use of RCM-MP led to faster data transmission, analysis, and decision-making and to increased accountability among levels of the health system. PMID- 27711035 TI - Announcement: National Protect Your Hearing Month - October 2016. AB - October is National Protect Your Hearing Month, a time to raise awareness about the causes and prevention of noise-induced hearing loss. Noise-induced hearing loss results from sounds in the environment that are too loud and can damage sensitive structures in the inner ear, even with a brief exposure. This type of hearing loss can result from occupational noise exposures, leisure activities such as sporting events or concerts, or use of personal listening devices. Noise induced hearing loss is permanent and cannot be reversed (1). PMID- 27711036 TI - Vaccination Coverage Among Children Aged 19-35 Months - United States, 2015. AB - Sustained high coverage with recommended vaccinations among children has kept many vaccine-preventable diseases at low levels in the United States (1). To assess coverage with vaccinations recommended for children by age 2 years in the United States (2), CDC analyzed data collected by the 2015 National Immunization Survey (NIS) for children aged 19-35 months (born January 2012-May 2014). Overall, coverage did not change during 2014-2015. Coverage in 2015 was highest for >=3 doses of poliovirus vaccine (93.7%), >=3 doses of hepatitis B vaccine (HepB) (92.6%), >=1 dose of measles, mumps, and rubella vaccine (MMR) (91.9%), and >=1 dose of varicella vaccine (91.8%). The data were also examined for potential vaccination coverage differences by race/ethnicity, poverty status, and urbanicity. Although disparities were noted for each of these factors, the most striking differences were seen for poverty status. Children living below the federal poverty level* had lower coverage with most of the vaccinations assessed compared with children living at or above the poverty level; the largest disparities were for rotavirus vaccine (66.8% versus 76.8%), >=4 doses of pneumococcal conjugate vaccine (PCV) (78.9% versus 87.2%), the full series of Haemophilus influenzae type b vaccine (Hib) (78.1% versus 85.5%), and >=4 doses of diphtheria, tetanus, and acellular pertussis vaccine (DTaP) (80.2% versus 87.1%). Although coverage was high in some groups, opportunities exist to continue to address disparities. Implementation of evidence-based interventions, including strategies to enhance access to vaccination services and systems strategies that can reduce missed opportunities, has the potential to increase vaccination coverage for children living below the poverty level and in rural areas (3). PMID- 27711037 TI - Vaccination Coverage Among Children in Kindergarten - United States, 2015-16 School Year. AB - State-mandated vaccination requirements for school entry protect children and communities against vaccine-preventable diseases (1). Each school year, federally funded immunization programs (e.g., states, territories, jurisdictions) collect and report kindergarten vaccination data to CDC. This report describes vaccination coverage estimates in all 50 states and the District of Columbia (DC), and the estimated number of kindergartners with at least one vaccine exemption in 47 states and DC, during the 2015-16 school year. Median vaccination coverage* was 94.6% for 2 doses of measles, mumps and rubella vaccine (MMR); 94.2% for diphtheria, tetanus, and acellular pertussis vaccine (DTaP); and 94.3% for 2 doses of varicella vaccine. MMR coverage increased in 32 states during the last year, and 22 states reported coverage >=95% (2). A total of 45 states and DC had either a grace period allowing students to attend school before providing documentation of vaccination or provisional enrollment that allows undervaccinated students to attend school while completing a catch-up schedule. Among the 23 states that were able to voluntarily report state-level data on grace period or provisional enrollment to CDC, a median of 2.0% of kindergartners were not documented as completely vaccinated and were attending school within a grace period or were provisionally enrolled. The median percentage of kindergartners with an exemption from one or more vaccinations? was 1.9%. State and local immunization programs, in cooperation with schools, can improve vaccination coverage by ensuring that all kindergartners are vaccinated during the grace period or provisional enrollment. PMID- 27711038 TI - Prevalence of Severe Joint Pain Among Adults with Doctor-Diagnosed Arthritis - United States, 2002-2014. AB - In the United States, arthritis is a leading cause of disability (1,2); arthritis affected an estimated 52.5 million (22.7%) adults in 2010-2012 and has been projected to affect 78.4 million adults by 2040 (3). Severe joint pain (SJP) can limit function and seriously compromise quality of life (4,5). To determine the prevalence of SJP among adults with doctor-diagnosed arthritis, and the trend in SJP from 2002 to 2014, CDC analyzed data from the National Health Interview Survey. In 2014, approximately one fourth of adults with arthritis had SJP (27.2%). Within selected groups, the age-standardized prevalence of SJP was higher among women (29.2%), non-Hispanic blacks (42.3%), Hispanics (35.8%), and persons with a disability (45.6%), and those who were unable to work (51.9%); prevalence also was higher among those who had fair or poor health (49.1%), obesity (31.7%), heart disease (34.1%), diabetes (40.9%), or serious psychological distress (56.3%). From 2002 to 2014, the age-standardized prevalence of SJP among adults with arthritis did not change (p = 0.14); however, the number of adults with SJP was significantly higher in 2014 (14.6 million) than in 2002 (10.5 million). A strategy to improve pain management (e.g., the 2016 National Pain Strategy*) has been developed, and more widespread dissemination of evidence-based interventions that reduce joint pain in adults with arthritis might reduce the prevalence of SJP. PMID- 27711039 TI - QuickStats: Percentage* of Children Aged 1-5 Years with Elevated Blood Lead Levels,? by Race/EthnicityS - National Health and Nutrition Examination Survey, United States, 1988-1994, 1999-2006, and 2007-2014. AB - From 1988-1994 to 2007-2014, the percentage of children aged 1-5 years with blood lead levels >=5 MUg/dL declined from 25.6% to 1.9%. Blood lead levels fell dramatically for all racial and ethnic groups. Despite the decline, in 2007-2014, non-Hispanic black children (4.0%) aged 1-5 years were twice as likely as non Hispanic white children (1.9%) and more than three times as likely as Mexican American children (1.1%) to have elevated blood lead levels. PMID- 27711040 TI - Notice to Readers: Update to Reporting of Pneumonia and Influenza Mortality. AB - The current issue of MMWR (week 39) will be the last to include data from the 122 Cities Mortality Reporting System (122 CMRS) in Notifiable Disease and Mortality Tables, Table III ("Deaths in 122 cities" [http://www.cdc.gov/mmwr/volumes/65/wr/mm6539md.htm?s_cid=mm6539md_w#table-17]). Beginning in the publication for the week ending October 8, 2016 (week 40), data from the National Center for Health Statistics (NCHS) Mortality Surveillance System will replace the information reported in Table III, and the 122 Cities Mortality Reporting System (122 CMRS) will be retired. The NCHS Mortality Surveillance System provides improvements in the data, including reports by the week of death and a consistent pneumonia and influenza (P&I) case definition across all sites. These improvements, along with recent and continuing increases in the timeliness of death certificate data, have led CDC to update the P&I mortality surveillance platform from the 122 CMRS to the NCHS Mortality Surveillance System. PMID- 27711041 TI - Characteristics of Children Aged <18 Years with Zika Virus Disease Acquired Postnatally - U.S. States, January 2015-July 2016. AB - Zika virus is an emerging mosquito-borne flavivirus that typically causes an asymptomatic infection or mild illness, although infection during pregnancy is a cause of microcephaly and other serious brain abnormalities. Guillain-Barre syndrome and other neurologic complications can occur in adults after Zika virus infection. However, there are few published reports describing postnatally acquired Zika virus disease among children. During January 2015-July 2016, a total of 158 cases of confirmed or probable postnatally acquired Zika virus disease among children aged <18 years were reported to CDC from U.S. states. The median age was 14 years (range = 1 month-17 years), and 88 (56%) were female. Two (1%) patients were hospitalized; none developed Guillain-Barre syndrome, and none died. All reported cases were travel-associated. Overall, 129 (82%) children had rash, 87 (55%) had fever, 45 (29%) had conjunctivitis, and 44 (28%) had arthralgia. Health care providers should consider a diagnosis of Zika virus disease in children who have an epidemiologic risk factor and clinically compatible illness, and should report cases to their state or local health department. PMID- 27711042 TI - The effects of human milk fortification on nutrients and milk properties. AB - OBJECTIVE: To investigate the effects of fortification and storage on nutrients and properties of various human milk (HM) types. STUDY DESIGN: Mother's own milk (MOM) and pasteurized donor human milk (DHM; n=118) were analyzed pre- and post fortification with Enfamil and Similac human milk fortifier (EHMF and SHMF) before and after 24 h of refrigerated storage. RESULTS: Milk fortified with SHMF had significantly greater osmolality, pH and lipase activity than EHMF. Changes in protein, pH and osmolality following refrigerated storage differed between fortifiers. When milk type was factored into the analysis, protein and lipase activity changes in fresh MOM differed significantly from DHM and frozen MOM. Analysis of UNF HM found higher protein levels in preterm vs term samples and in MOM vs DHM. CONCLUSION: Nutrient composition of HM varies significantly by milk type. Although fortifiers enhance select nutrients, each has the potential to affect HM properties in a unique way and these affects may vary by milk type. PMID- 27711043 TI - Right ventricular performance using myocardial deformation imaging in infants with bronchopulmonary dysplasia. AB - OBJECTIVE: Right ventricular (RV) performance among infants with bronchopulmonary dysplasia (BPD) remains poorly understood. We tested the hypothesis that myocardial deformation imaging (MDI) strain and strain rate would allow for differentiation between infants with severe and milder forms of BPD, independent of tissue Doppler imaging (TDI) and superior to conventional echocardiographic measurements. STUDY DESIGN: Infants with various severities of BPD (11 with none or mild, 13 with moderate and 10 with severe) underwent conventional echocardiography, TDI and MDI assessments at >36 weeks of corrected gestational age. BPD severity grading was determined according to the National Institutes of Child Health and Disease workshop rating scale by physicians blinded to the echocardiogram results. Group data were compared with one-way analysis of variance or Kruskal-Wallis tests, with post hoc multiple comparisons. RESULTS: No differences in traditional echocardiographic parameters or TDI among the three BPD severity groups were observed; none of the infants had evidence of pulmonary hypertension. Using MDI, infants with severe BPD had lower peak global systolic strain than did infants with moderate BPD (P<0.01) or mild/none BPD (P<0.01). Early and late diastolic strain rate measurements were similar across the three groups. CONCLUSIONS: Among infants with severe forms of BPD, evidence of abnormal RV systolic function was detected with MDI, but not traditional echocardiographic or TDI measurements. Infants with severe forms of BPD may represent a particularly high-risk subgroup for decreased RV performance warranting cardiac surveillance. MDI should be considered as a method to quantitate RV function in this population.

AB - OBJECTIVE: To evaluate the maternal-fetal management and follow-up of infants at risk for congenital syphilis. STUDY DESIGN: Monocentric retrospective cohort study at the Felix Guyon Hospital, Saint-Denis, La Reunion between January 2008 and December 2014. Management of 38 pregnancies (35 women, 39 fetuses) with a positive syphilis serology was evaluated according to the Centers for Disease Control and Prevention (CDC) guidelines. RESULTS: A total of 68% (n=26) of pregnancies were screened before 16 weeks of gestation, and 26% (n=10) had appropriate treatment. Adverse outcomes were noted in 45% of pregnancies. Neonatal serology was not performed in 7 live-born neonates (19%) and 33 infants were classifiable according to the four CDC scenarios. In the infants, adequate complementary evaluation and appropriate treatment were noted in 42% (n=13) and 55% (n=17) of cases, respectively. Rate of infant follow-up was 76% (n=16). No treatment failure was observed in infants. CONCLUSION: Reinforcement of public health policies and a better sensitization, training and collaboration among perinatal caregivers are warranted given the gaps revealed in our study. PMID- 27711046 TI - Histone Lysine Demethylases of JMJD2 or KDM4 Family are Important Epigenetic Regulators in Reward Circuitry in the Etiopathology of Depression. AB - Major depressive disorder (MDD) is debilitating mental illness and is one of the leading contributors to global burden of disease, but unfortunately newer and better drugs are not forthcoming. The reason is lack of complete understanding of molecular mechanisms underlying the development of this disorder. Recent research shows dysregulation in epigenetic regulatory mechanisms, particularly the transcriptionally repressive di- and tri-methylation of histone 3 lysine 9 (H3K9me2/me3) in nucleus accumbens (NAc), a critical region of the reward pathway involved in the development of anhedonia, the hallmark of depression. However, the role of histone lysine demethylases, which can remove methylation from H3K9, in particular Jumonji domain containing demethylases 2 or Jmjd2 family, has not been studied. Using social defeat stress-induced mouse model of depression, this study uncovered that transcripts of most of the Jmjd2 members were unchanged after 5 days of defeat during the onset of depression, but were downregulated after 10 days of defeat in full-blown depression. Blocking the Jumonji domain containing demethylases by chronic administration of inhibitors dimethyloxalylglycine (DMOG) and ML324 resulted in depression-like phenotype even in absence of stress exposure, which was associated with an increase in transcriptionally repressive epigenetic marks H3K9me2/me3 in NAc, causing altered neuroplastic changes as reported in NAc in depression models. Thus, we report for the first time that Jmjd2 class demethylases are critical epigenetic regulators involved in etiopathology of depression and related disorders and activation of these demethylases can be a good strategy in the treatment of MDD and related psychiatric disorders. PMID- 27711045 TI - Non-invasive inhaled nitric oxide in the treatment of hypoxemic respiratory failure in term and preterm infants. AB - OBJECTIVES: Inhaled nitric oxide (iNO) is effective in conjunction with tracheal intubation (TI) and mechanical ventilation (MV) for treating arterial pulmonary hypertension and hypoxemic respiratory failure (HRF) in near-term and term newborns. Non-invasive respiratory support with nasal continuous positive airway pressure (CPAP) is increasingly used to avoid morbidity associated with TI and MV, yet the effectiveness of iNO delivery via nasal CPAP remains unknown. To evaluate the effectiveness of iNO delivered via the bubble nasal CPAP system in term and preterm newborns with HRF. STUDY DESIGN: Electronic medical records from all infants admitted to the neonatal intensive care unit (NICU) during 2005 to 2014 (n=10, 895) were screened for treatment with iNO therapy for HRF. Detailed data on population characteristics and cardiorespiratory, iNO and respiratory support indices were abstracted for all infants, who were administered iNO non invasively using bubble nasal CPAP. Change in relevant indices at baseline (before initiating non-invasive iNO) and at 3, 6, 12 and 24 h after non-invasive iNO therapy were analyzed using repeated measures analysis of variance. RESULTS: Of 795 infants treated with iNO (7.3% of total NICU admissions) over a 10-year period, 107 infants (13.4% of iNO treated) with birth weight 2448+/-1112 g and gestational age 35.3+/-5.8 weeks received iNO non-invasively. 25 infants received iNO exclusively non-invasively, whereas in remaining 82 infants non-invasive route followed invasive delivery via TI and MV. Indications for using non invasive iNO included idiopathic pulmonary hypertension (39%), congenital heart disease (37%), bronchopulmonary dysplasia (10%), meconium aspiration syndrome (9%) and congenital diaphragmatic hernia (5%). Over the 24 h following initiation of non-invasive iNO, fractional oxygen requirements decreased (0.38 to 0.32; P<0.0005) and SpO2 increased (90.7 to 91.6%; P<0.01) with no significant changes in heart rate, respiratory rate, blood pressure, pH and PaCO2. On average non invasive iNO was initiated on day of life 9 with a maximal dose was 20 p.p.m. The average duration of iNO therapy and the duration over which it was weaned off were 134 and 51 h, respectively. Analysis of environmental gases during non invasive iNO therapy revealed median ambient nitrogen dioxide and nitric oxide levels of 0.30 and 0.01 p.p.m., respectively. CONCLUSIONS: Initiation of iNO in infants on bubble nasal CPAP or continuation of iNO in infants transitioning from MV to bubble nasal CPAP is associated with improved oxygenation during HRF in term and preterm infants. Non-invasive iNO may have a synergistic effect with airway recruitment strategies such as nasal CPAP. PMID- 27711047 TI - The Trace Amine-Associated Receptor 1 Agonist RO5256390 Blocks Compulsive, Binge like Eating in Rats. AB - Compulsive, binge eating of highly palatable food constitutes a core feature of some forms of obesity and eating disorders, as well as of the recently proposed disorder of food addiction. Trace amine-associated receptor 1 (TAAR1) is a highly conserved G-protein-coupled receptor bound by endogenous trace amines. TAAR1 agonists have been shown to reduce multiple behavioral effects of drugs of abuse through their actions on the mesocorticolimbic system. In this study, we hypothesized that TAAR1 may have a role in compulsive, binge-like eating; we tested this hypothesis by assessing the effects of a TAAR1 agonist, RO5256390, in multiple excessive feeding-related behaviors induced by limiting access to a highly palatable diet in rats. Our results show that RO5256390 blocked binge-like eating in rats responding 1 h per day for a highly palatable sugary diet. Consistent with a palatability-selective effect, drug treatment selectively reduced the rate and regularity of palatable food responding, but it did not affect either baseline intake or food restriction-induced overeating of the standard chow diet. Furthermore, RO5256390 fully blocked compulsive-like eating when the palatable diet was offered in an aversive compartment of a light/dark conflict box, and blocked the conditioned rewarding properties of palatable food, as well as palatable food-seeking behavior in a second-order schedule of reinforcement. Drug treatment had no effect on either anxiety-like or depressive like behavior, and it did not affect control performance in any of the tests. Importantly, rats exposed to palatable food showed decreased TAAR1 levels in the medial prefrontal cortex (mPFC), and RO5256390 microinfused into the infralimbic, but not prelimbic, subregion of the mPFC-reduced binge-like eating. Altogether, these results provide evidence for TAAR1 agonism as a novel pharmacological treatment for compulsive, binge eating. PMID- 27711048 TI - A Single Dose, Randomized, Controlled Proof-Of-Mechanism Study of a Novel Vasopressin 1a Receptor Antagonist (RG7713) in High-Functioning Adults with Autism Spectrum Disorder. AB - The core symptoms of autism spectrum disorder (ASD) include impaired social communication, repetitive behaviors, and restricted interests. No effective pharmacotherapy for these core deficits exists. Within the domain of social communication, the vasopressin system is implicated in social cognition and social signaling deficits of ASD, and represents a potential therapeutic target. We assessed the effects of a single 20 mg intravenous dose of the arginine vasopressin receptor 1A (V1a) antagonist, RG7713, on exploratory biomarkers (eye tracking), behavioral and clinical measures of social cognition and communication (affective speech recognition (ASR), reading the mind in the eyes, olfactory identification, scripted interaction), and safety and tolerability in a multicenter, randomized, double-blind, placebo-controlled, cross-over study of 19 high-functioning adult male subjects with DSM-IV Autistic Disorder (age 18-45 years; full scale IQ >70; ABC-Irritability subscale ?13). Eye-tracking showed an increase in biological motion orienting preference with RG7713 (ES=0.8, p=0.047) and a non-significant improvement in the composite score (ES=0.2, p=0.29). RG7713 reduced ability to detect lust (ES=-0.8, p=0.03) and fear (ES=-0.7, p=0.07) in ASR. However, when all eight individual emotion subscales were combined into an overall ASR performance score, the reduction was non-significant (ES=-0.1, p=0.59). Thirteen adverse events were reported in 10 subjects; all were of mild (11/13) or moderate (2/13) severity. Although interpretation should be cautious due to multiple comparisons and small sample size, these results provide preliminary evidence from experimental and behavioral biomarkers, that blockade of the V1a receptor may improve social communication in adults with high functioning ASD.

PMID- 27711049 TI - Clozapine Modulates Glucosylceramide, Clears Aggregated Proteins, and Enhances ATG8/LC3 in Caenorhabditis elegans. AB - Defining the mechanisms of action of the antipsychotic drug (APD), clozapine, is of great importance, as clozapine is more effective and has therapeutic benefits in a broader range of psychiatric disorders compared with other APDs. Its range of actions have not been fully characterized. Exposure to APDs early in development causes dose-dependent developmental delay and lethality in Caenorhabditis elegans. A previous genome-wide RNAi screen for suppressors of clozapine-induced developmental delay and lethality revealed 40 candidate genes, including sms-1, which encodes a sphingomyelin synthase. One sms-1 isoform is expressed in the C. elegans pharynx, and its transgene rescues the sms-1 mutant phenotype. We examined pharyngeal pumping and observed that clozapine-induced inhibition of pharyngeal pumping requires sms-1, a finding that may explain the role of the gene in mediating clozapine-induced developmental delay/lethality. By analyzing multiple enzymes involved in sphingolipid metabolism, and by observing the effect of addition of various lipids directly to the worms, we suggest that glucosylceramide may be a key mediator of the effects of clozapine. We further observed that clozapine clears protein aggregates, such as alpha-synuclein, PolyQ protein, and alpha-1-antitrypsin mutant protein. In addition, it enhances ATG8/LC3. We conclude that clozapine appears to affect the development and induce lethality of worms, in part, through modulating glucosylceramide. We discuss the possible connections among glucosylceramide, protein aggregate clearance, and autophagy. Interactions, including mechanistic pathways involving these elements, may underlie some of the clinical effects of clozapine. PMID- 27711050 TI - Preparing monodisperse macromolecular samples for successful biological small angle X-ray and neutron-scattering experiments. AB - Small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) are techniques used to extract structural parameters and determine the overall structures and shapes of biological macromolecules, complexes and assemblies in solution. The scattering intensities measured from a sample contain contributions from all atoms within the illuminated sample volume, including the solvent and buffer components, as well as the macromolecules of interest. To obtain structural information, it is essential to prepare an exactly matched solvent blank so that background scattering contributions can be accurately subtracted from the sample scattering to obtain the net scattering from the macromolecules in the sample. In addition, sample heterogeneity caused by contaminants, aggregates, mismatched solvents, radiation damage or other factors can severely influence and complicate data analysis, so it is essential that the samples be pure and monodisperse for the duration of the experiment. This protocol outlines the basic physics of SAXS and SANS, and it reveals how the underlying conceptual principles of the techniques ultimately 'translate' into practical laboratory guidance for the production of samples of sufficiently high quality for scattering experiments. The procedure describes how to prepare and characterize protein and nucleic acid samples for both SAXS and SANS using gel electrophoresis, size-exclusion chromatography (SEC) and light scattering. Also included are procedures that are specific to X-rays (in-line SEC-SAXS) and neutrons, specifically preparing samples for contrast matching or variation experiments and deuterium labeling of proteins. PMID- 27711051 TI - Serial sequencing of isolength RAD tags for cost-efficient genome-wide profiling of genetic and epigenetic variations. AB - Isolength restriction site-associated DNA (isoRAD) sequencing is a very simple but powerful approach that was originally developed for genome-wide genotyping at minimal labor and cost, and it has recently extended its applicability to allow quantification of DNA methylation levels. The isoRAD method is distinct from other genotyping-by-sequencing (GBS) methods because of its use of special restriction enzymes to produce isolength tags (32-36 bp), and sequencing of these uniform tags can bring many benefits. However, the relatively short tags produced by the original protocol are mostly suited to single-end (SE) sequencing (36-50 bp), and therefore they cannot efficiently match the gradually increased sequencing capacity of next-generation sequencing (NGS) platforms. To address this issue, we describe an advanced protocol that allows the preparation of five concatenated isoRAD tags for Illumina paired-end (PE) sequencing (100-150 bp). The configuration of the five concatenated tags is highly flexible, and can be defined by users to work with a desired combination of samples and/or restriction enzymes to suit specific research purposes. In comparison with the original protocol, the advanced protocol has an additional digestion and ligation step, and library preparation can be completed in ~8 h. PMID- 27711052 TI - Remodeling somatic nuclei via exogenous expression of protamine 1 to create spermatid-like structures for somatic nuclear transfer. AB - This protocol describes how to convert the chromatin structure of sheep and mouse somatic cells into spermatid-like nuclei through the heterologous expression of the protamine 1 gene (Prm1). Furthermore, we also provide step-by-step instructions for somatic cell nuclear transfer (SCNT) of Prm1-remodeled somatic nuclei in sheep oocytes. There is evidence that changing the organization of a somatic cell nucleus with that which mirrors the spermatozoon nucleus leads to better nuclear reprogramming. The protocol may have further potential application in determining the protamine and histone footprints of the whole genome; obtaining 'gametes' from somatic cells; and furthering understanding of the molecular mechanisms regulating the maintenance of DNA methylation in imprinted control regions during male gametogenesis. The protocol is straightforward, and it requires 4 weeks from the establishment of the cell lines to their transfection and the production of cloned blastocysts. It is necessary for researchers to have experience in cell biology and embryology, with basic skills in molecular biology, to carry out the protocol. PMID- 27711053 TI - Modeling and correction of structural variations in patient-derived iPSCs using CRISPR/Cas9. AB - Genome engineering technology using engineered nucleases has been rapidly developing, enabling the efficient correction of simple mutations. However, the precise correction of structural variations (SVs) such as large inversions remains limited. Here we describe a detailed procedure for the modeling or correction of large chromosomal rearrangements and short nucleotide repeat expansions using engineered nucleases in human induced pluripotent stem cells (hiPSCs) from a healthy donor and patients with SVs. This protocol includes the delivery of engineered nucleases with no donor template to hiPSCs, and genotyping and derivation/characterization of gene-manipulated hiPSC clones. With engineered nucleases, genomic inversions, reversions, and deletions of short nucleotide expansions can be identified in 2 weeks, and desired clones can be generated in as little as 3-4 weeks. This protocol enables the correction of large inverted segments and short nucleotide repeat expansions in diseases such as hemophilia A, fragile X syndrome, Hunter syndrome, and Friedreich's ataxia.

PMID- 27711054 TI - The scaffold protein Tks4 is required for the differentiation of mesenchymal stromal cells (MSCs) into adipogenic and osteogenic lineages. AB - The commitment steps of mesenchymal stromal cells (MSCs) to adipogenic and other lineages have been widely studied but not fully understood. Therefore, it is critical to understand which molecules contribute to the conversion of stem cells into differentiated cells. The scaffold protein Tks4 plays a role in podosome formation, EGFR signaling and ROS production. Dysfunction of Tks4 causes a hereditary disease called Frank-ter Haar syndrome with a variety of defects concerning certain mesenchymal tissues (bone, fat and cartilage) throughout embryogenic and postnatal development. In this study, we aimed to analyze how the mutation of Tks4 affects the differentiation potential of multipotent bone marrow MSCs (BM-MSCs). We generated a Tks4 knock-out mouse strain on C57Bl/6 background, and characterized BM-MSCs isolated from wild type and Tks4-/- mice to evaluate their differentiation. Tks4-/- BM-MSCs had reduced ability to differentiate into osteogenic and adipogenic lineages compared to wild type. Studying the expression profile of a panel of lipid-regulated genes during adipogenic induction revealed that the expression of adipogenic transcription factors, genes responsible for lipid droplet formation, sterol and fatty acid metabolism was delayed or reduced in Tks4-/- BM-MSCs. Taken together, these results establish a novel function for Tks4 in the regulation of MSC differentiation.

PMID- 27711063 TI - Signals from the gut microbiota to distant organs in physiology and disease. AB - The ecosystem of the human gut consists of trillions of bacteria forming a bioreactor that is fueled by dietary macronutrients to produce bioactive compounds. These microbiota-derived metabolites signal to distant organs in the body, which enables the gut bacteria to connect to the immune and hormone system, to the brain (the gut-brain axis) and to host metabolism, as well as other functions of the host. This microbe-host communication is essential to maintain vital functions of the healthy host. Recently, however, the gut microbiota has been associated with a number of diseases, ranging from obesity and inflammatory diseases to behavioral and physiological abnormalities associated with neurodevelopmental disorders. In this Review, we will discuss microbiota-host cross-talk and intestinal microbiome signaling to extraintestinal organs. We will review mechanisms of how this communication might contribute to host physiology and discuss how misconfigured signaling might contribute to different diseases.

(Clin Transl Gastroenterol 7: e187; doi:10.1038/ctg.2016.44) investigated the effects of rifaximin in a mouse model of MHE-associated microbiota without concomitant liver disease. In addition to some impact on the composition of microbiota, rifaximin altered bacterial functions, ameliorated local and systemic inflammation, and reduced enterocyte glutaminase activity. We discuss these effects as well as the interpretation of the permeability studies, given the potential interaction of dysbiosis with dysfunctional intestinal barrier, leading to systemic inflammation and increased uptake of bacterial metabolites that contribute to MHE in the presence of hepatic dysfunction. PMID- 27711070 TI - Universal tumor screening for Lynch syndrome: health-care providers' perspectives. AB - PURPOSE: Population-based reflex testing of colorectal tumors can identify individuals with Lynch syndrome (LS), but there is debate regarding the type of patient discretion such a program warrants. We examined health-care providers' views and experiences to inform the design of a reflex-testing program and their perspectives regarding an opt-out option. METHODS: We interviewed providers managing LS or colorectal cancer patients, including surgeons, genetic counselors, oncologists, primary-care physicians, and gastroenterologists. Qualitative data were analyzed thematically using constant comparison techniques. RESULTS: Providers supported a reflex-testing program because of the current lack of coordinated immunohistochemistry (IHC) testing and underascertainment of LS patients as well as the opportunity to standardize the increasing use of genomic tests in practice. Most supported an opt-out after reflex testing because they felt that IHC is akin to other pathology tests, which are not optional. Some favored an opt-out before testing because of concern for patients experiencing distress, insurance discrimination, or a diagnostic odyssey that may be inconclusive. CONCLUSION: Providers support a reflex-testing program to improve the identification and management of suspected LS patients. However, how to support meaningful information provision to enable an opt-out without jeopardizing testing uptake and the anticipated public health benefits remains a policy challenge.Genet Med advance online publication 06 October 2016. PMID- 27711071 TI - Increasing the sensitivity of clinical exome sequencing through improved filtration strategy. AB - BACKGROUND: Clinical exome sequencing (CES) has greatly improved the diagnostic process for individuals with suspected genetic disorders. However, the majority remains undiagnosed after CES. Although understanding potential reasons for this limited sensitivity is critical for improving the delivery of clinical genomics, research in this area has been limited. MATERIALS AND METHODS: We first calculated the theoretical maximum sensitivity of CES by analyzing >100 families in whom a Mendelian phenotype is mapped to a single locus. We then tested the hypothesis that positional mapping can limit the search space and thereby facilitate variant interpretation by reanalyzing 33 families with "negative" CES and applying positional mapping. RESULTS: We found that >95% of families who map to a single locus harbored genic (as opposed to intergenic) variants that are potentially identifiable by CES. Our reanalysis of "negative" CES revealed likely causal variants in the majority (88%). Several of these solved cases have undergone negative whole-genome sequencing. CONCLUSION: The discrepancy between the theoretical maximum and the actual clinical sensitivity of CES is primarily in the variant filtration rather than the variant capture and sequencing phase. The solution to negative CES is not necessarily in expanding the coverage but rather in devising approaches that improve variant filtration. We suggest that positional mapping is one such approach.Genet Med advance online publication 06 October 2016. PMID- 27711072 TI - Numerous Brugada syndrome-associated genetic variants have no effect on J-point elevation, syncope susceptibility, malignant cardiac arrhythmia, and all-cause mortality. AB - PURPOSE: We investigated whether Brugada syndrome (BrS)-associated variants identified in the general population have an effect on J-point elevation as well as whether carriers of BrS variants were more prone to experience syncope and malignant ventricular arrhythmia and had increased mortality compared with noncarriers. METHODS: All BrS-associated variants were identified using the Human Gene Mutation Database (HGMD). Individuals were randomly selected from a general population study using whole-exome sequencing data (n = 870) and genotype array data (n = 6,161) and screened for BrS-associated variants. Electrocardiograms (ECG) were analyzed electronically, and data on syncope, ventricular arrhythmias, and mortality were obtained from administrative health-care registries. RESULTS: In HGMD, 382 BrS-associated genetic variants were identified. Of these, 28 variants were identified in the study cohort. None of the carriers presented with type 1 BrS ECG pattern. Mean J-point elevation in V1 and V2 were within normal guideline limits for carriers and noncarriers. There was no difference in syncope susceptibility (carriers 8/624; noncarriers 98/5,562; P = 0.51), ventricular arrhythmia (carriers 4/620; noncarriers 9/5,524; P = 0.24), or overall mortality (hazard ratio 0.93, 95% CI 0.63-1.4). CONCLUSIONS: Our data indicate that a significant number of BrS-associated variants are not the monogenic cause of BrS.Genet Med advance online publication 06 October 2016. PMID- 27711074 TI - P300/CBP-associated factor (PCAF) inhibits the growth of hepatocellular carcinoma by promoting cell autophagy. AB - Aberrant autophagic processes have been found to have fundamental roles in the pathogenesis of different kinds of tumors, including hepatocellular carcinoma (HCC). P300/CBP-associated factor (PCAF), a histone acetyltransferase (HAT), performs its function by acetylating both histone and non-histone proteins. Our previous studies showed that PCAF was downregulated in HCC tissues and its high expression was significantly associated with patient survival after surgery, serving as a prognostic marker. In this study we found that overexpression of PCAF induced autophagy of HCC cells and its knockdown depressed autophagy. As type II programmed cell death, autophagy induced by PCAF-elicited cell death in HCC cells. In vivo experiments confirmed that PCAF-induced autophagy inhibited tumor growth. Subsequent in vitro experiments showed that PCAF promoted autophagy by inhibiting Akt/mTOR signaling pathway. Our findings show that PCAF is a novel modulator of autophagy in HCC, and can serve as an attractive therapeutic strategy of HCC treatment. PMID- 27711075 TI - Stat3 modulates chloride channel accessory protein expression in normal and neoplastic mammary tissue. AB - Mammary gland regression at the cessation of lactation (involution) is an exquisitely orchestrated process of cell death and tissue remodelling in which Stat3 signalling has an essential role. The involution microenvironment of the mammary gland is considered to be pro-tumourigenic and a proportion of cases of pregnancy-associated breast cancer are suggested to originate in tandem with involution. However, the apparent paradox that STAT3 is required for cell death in normal mammary gland, but is associated with breast cancer cell survival, has not been resolved. Herein, we investigate Stat3-mediated regulation of expression of members of the calcium-activated chloride channel regulator (CLCA) family of proteins during involution and mammary carcinogenesis. Using the conditionally immortal mammary epithelial cell line KIM-2, together with mice exhibiting mammary epithelial cell-specific deletion of Stat3 during lactation, we demonstrate that expression of mCLCA1 and mCLCA2 is elevated in concert with activation of Stat3. By contrast, murine CLCA5 (mCLCA5), the murine orthologue of human CLCA2, is significantly upregulated at 24, 72 and 96 h of involution in Stat3 knockout mice, suggesting a reciprocal regulation of these proteins by Stat3 in vivo. Interestingly, orthotopic tumours arising from transplantation of 4T1 murine mammary tumour cells exhibit both phosphorylated Stat3 and mCLCA5 expression. However, we demonstrate that expression is highly compartmentalized to distinct subpopulations of cells, and that Stat3 retains a suppressive effect on mCLCA5 expression in 4T1 tumour cells. These findings enhance our understanding of the regulation of CLCA channel expression both in vitro and in vivo, and in particular, demonstrate that expression of mCLCA1 and mCLCA2 during involution is profoundly dependent upon Stat3, whereas the relationship between mCLCA5 and Stat3 activity is reciprocal and restricted to different subpopulations of cells. PMID- 27711073 TI - Genetic modifiers of CHEK2*1100delC-associated breast cancer risk. AB - PURPOSE: CHEK2*1100delC is a founder variant in European populations that confers a two- to threefold increased risk of breast cancer (BC). Epidemiologic and family studies have suggested that the risk associated with CHEK2*1100delC is modified by other genetic factors in a multiplicative fashion. We have investigated this empirically using data from the Breast Cancer Association Consortium (BCAC). METHODS: Using genotype data from 39,139 (624 1100delC carriers) BC patients and 40,063 (224) healthy controls from 32 BCAC studies, we analyzed the combined risk effects of CHEK2*1100delC and 77 common variants in terms of a polygenic risk score (PRS) and pairwise interaction. RESULTS: The PRS conferred odds ratios (OR) of 1.59 (95% CI: 1.21-2.09) per standard deviation for BC for CHEK2*1100delC carriers and 1.58 (1.55-1.62) for noncarriers. No evidence of deviation from the multiplicative model was found. The OR for the highest quintile of the PRS was 2.03 (0.86-4.78) for CHEK2*1100delC carriers, placing them in the high risk category according to UK NICE guidelines. The OR for the lowest quintile was 0.52 (0.16-1.74), indicating a lifetime risk close to the population average. CONCLUSION: Our results confirm the multiplicative nature of risk effects conferred by CHEK2*1100delC and the common susceptibility variants. Furthermore, the PRS could identify carriers at a high lifetime risk for clinical actions.Genet Med advance online publication 06 October 2016. PMID- 27711076 TI - Cnbp ameliorates Treacher Collins Syndrome craniofacial anomalies through a pathway that involves redox-responsive genes. AB - Treacher Collins Syndrome (TCS) is a rare congenital disease (1:50 000 live births) characterized by craniofacial defects, including hypoplasia of facial bones, cleft palate and palpebral fissures. Over 90% of the cases are due to mutations in the TCOF1 gene, which codifies the nucleolar protein Treacle. Here we report a novel TCS-like zebrafish model displaying features that fully recapitulate the spectrum of craniofacial abnormalities observed in patients. As it was reported for a Tcof1+/- mouse model, Treacle depletion in zebrafish caused reduced rRNA transcription, stabilization of Tp53 and increased cell death in the cephalic region. An increase of ROS along with the overexpression of redox responsive genes was detected; furthermore, treatment with antioxidants ameliorated the phenotypic defects of craniofacial anomalies in TCS-like larvae. On the other hand, Treacle depletion led to a lowering in the abundance of Cnbp, a protein required for proper craniofacial development. Tcof1 knockdown in transgenic zebrafish overexpressing cnbp resulted in barely affected craniofacial cartilage development, reinforcing the notion that Cnbp has a role in the pathogenesis of TCS. The cnbp overexpression rescued the TCS phenotype in a dose dependent manner by a ROS-cytoprotective action that prevented the redox responsive genes' upregulation but did not normalize the synthesis of rRNAs. Finally, a positive correlation between the expression of CNBP and TCOF1 in mesenchymal cells from both control and TCS subjects was found. Based on this, we suggest CNBP as an additional target for new alternative therapeutic treatments to reduce craniofacial defects not only in TCS but also in other neurocristopathies. PMID- 27711077 TI - RelB/NF-kappaB links cell cycle transition and apoptosis to endometrioid adenocarcinoma tumorigenesis. AB - Dysfunction of nuclear factor-kappaB (NF-kappaB) signaling has been causally associated with numerous human malignancies. Although the NF-kappaB family of genes has been implicated in endometrial carcinogenesis, information regarding the involvement of central regulators of NF-kappaB signaling in human endometrial cancer (EC) is limited. Here, we investigated the specific roles of canonical and noncanonical NF-kappaB signaling in endometrial tumorigenesis. We found that NF kappaB RelB protein, but not RelA, displayed high expression in EC samples and cell lines, with predominant elevation in endometrioid adenocarcinoma (EEC). Moreover, tumor cell-intrinsic RelB was responsible for the abundant levels of c Myc, cyclin D1, Bcl-2 and Bcl-xL, which are key regulators of cell cycle transition, apoptosis and proliferation in EEC. In contrast, p27 expression was enhanced by RelB depletion. Thus, increased RelB in human EC is associated with enhanced EEC cell growth, leading to endometrial cell tumorigenicity. Our results reveal that regulatory RelB in noncanonical NF-kappaB signaling may serve as a therapeutic target to block EC initiation. PMID- 27711078 TI - Attenuated DNA damage repair delays therapy-related myeloid neoplasms in a mouse model. AB - Therapy-related cancers are potentially fatal late life complications for patients who received radio- or chemotherapy. So far, the mouse model showing reduction or delay of these diseases has not been described. We found that the disruption of Aplf in mice moderately attenuated DNA damage repair and, unexpectedly, impeded myeloid neoplasms after exposure to ionizing radiation (IR). Irradiated mutant mice showed higher rates of p53-dependent cell death, fewer chromosomal translocations, and a delay in malignancy-induced mortality. Simultaneous deficiency of p53 abrogated IR-induced apoptosis and the benefit of impaired DNA repair on mortality in irradiated Aplf-/- mice. Depletion of APLF in non-tumorigenic human cells also markedly reduced the risk of radiation-induced chromosomal aberrations. We therefore conclude that proficient DNA damage repair may promote chromosomal aberrations in normal tissues after irradiation and induce malignant evolution, thus illustrating the potential benefit in sensitizing p53 function by manipulating DNA repair efficiency in cancer patients undergoing genotoxic therapies. PMID- 27711079 TI - Inactivation of Sirt1 in mouse livers protects against endotoxemic liver injury by acetylating and activating NF-kappaB. AB - Sirtuin 1 (Sirt1) is a deacetylase that regulates many cellular processes in the liver, and so far its role in endotoxemic liver injury is elusive. So we conditionally inactivate Sirt1 in murine hepatocytes to determine its role in d galactosamine (GalN)/lipopolysaccharide (LPS)-induced liver damage, which is a well-established experimental model mimicking septic liver injury and fulminant hepatitis. Ablation of Sirt1 shows remarkable protection against GalN/LPS-induced liver injury, which is a result of enhanced NF-kappaB response because knockdown of RelA/p65 negates the protective effect of Sirt1 knockout. Mechanistically, NF kappaB p65 is maintained in a hyperacetylated, DNA-binding competent state in tumor necrosis factor-alpha (TNF-alpha)-challenged albumin-Cre+ (AlbCre+) hepatocytes. Transfection of hepatocytes with a recombinant acetylated p65 expression construct replicates the protection afforded by Sirt1 knockout. Transfection of AlbCre+ hepatocytes with a recombinant wild-type Sirt1 construct, rather than a deacetylase-defective one, compromises NF-kappaB activation and resensitizes hepatocytes to TNF-alpha-induced apoptosis. Taken together, our results demonstrate that Sirt1 deacetylates p65 and compromises NF-kappaB activity in hepatocytes when confronted with LPS/TNF-alpha stimulation, leading to increased susceptibility to endotoxemic injury. These findings identify a possible protein effector to maneuver the hepatic NF-kappaB signaling pathway under inflammatory circumstances and a feasible way to increase hepatocellular resistance to endotoxin/TNF-alpha toxicity.

PMID- 27711080 TI - Adeno-associated virus-mediated CASQ2 delivery rescues phenotypic alterations in a patient-specific model of recessive catecholaminergic polymorphic ventricular tachycardia. AB - Catecholaminergic Polymorphic Ventricular Tachycardia type 2 (CPVT2) is a highly lethal recessive arrhythmogenic disease caused by mutations in the calsequestrin 2 (CASQ2) gene. We have previously demonstrated that viral transfer of the wild type (WT) CASQ2 gene prevents the development of CPVT2 in a genetically induced mouse model of the disease homozygous carrier of the R33Q mutation. In the present study, we investigated the efficacy of the virally mediated gene therapy in cardiomyocytes (CMs) differentiated from induced pluripotent stem cells (iPSCs) obtained from a patient carrying the homozygous CASQ2-G112+5X mutation. To this end, we infected cells with an Adeno-Associated Viral vector serotype 9 (AAV9) encoding the human CASQ2 gene (AAV9-hCASQ2). Administration of the human WT CASQ2 gene was capable and sufficient to restore the physiological expression of calsequestrin-2 protein and to rescue functional defects of the patient specific iPSC-derived CMs. Indeed, after viral gene transfer, we observed a remarkable decrease in the percentage of delayed afterdepolarizations (DADs) developed by the diseased CMs upon adrenergic stimulation, the calcium transient amplitude was re-established and the density and duration of calcium sparks were normalized. We therefore demonstrate the efficacy of the AAV9-mediated gene replacement therapy for CPVT2 in a human cardiac-specific model system, supporting the view that the gene-therapy tested is curative in models with different human mutations of CPVT. PMID- 27711081 TI - Hypoxia-induced expression of cellular prion protein improves the therapeutic potential of mesenchymal stem cells. AB - Mesenchymal stem cells (MSCs) are 'adult' multipotent cells that promote regeneration of injured tissues in vivo. However, differences in oxygenation levels between normoxic culture conditions (21% oxygen) and both the MSC niche (2 8% oxygen) and ischemic injury-induced oxidative stress conditions in vivo have resulted in low efficacy of MSC therapies in both pre-clinical and clinical studies. To address this issue, we examined the effectiveness of hypoxia preconditioning (2% oxygen) for enhancing the bioactivity and tissue-regenerative potential of adipose-derived MSCs. Hypoxia preconditioning enhanced the proliferative potential of MSCs by promoting the expression of normal cellular prion protein (PrPC). In particular, hypoxia preconditioning-mediated MSC proliferation was regulated by PrPC-dependent JAK2 and STAT3 activation. In addition, hypoxia preconditioning-induced PrPC regulated superoxide dismutase and catalase activity, and inhibited oxidative stress-induced apoptosis via inactivation of cleaved caspase-3. In a murine hindlimb ischemia model, hypoxia preconditioning enhanced the survival and proliferation of transplanted MSCs, ultimately resulting in improved functional recovery of the ischemic tissue, including the ratio of blood flow perfusion, limb salvage, and neovascularization. These results suggest that Hypo-MSC offer a therapeutic strategy for accelerated neovasculogenesis in ischemic diseases, and that PrPC comprises a potential target for MSC-based therapies.

PMID- 27711083 TI - RADVAN: a randomised phase 2 trial of WBRT plus vandetanib for melanoma brain metastases - results and lessons learnt. AB - BACKGROUND: Brain metastases occur in up to 75% of patients with advanced melanoma. Most are treated with whole-brain radiotherapy (WBRT), with limited effectiveness. Vandetanib, an inhibitor of vascular endothelial growth factor receptor, epidermal growth factor receptor and rearranged during transfection tyrosine kinases, is a potent radiosensitiser in xenograft models. We compared WBRT with WBRT plus vandetanib in the treatment of patients with melanoma brain metastases. METHODS: In this double-blind, multi-centre, phase 2 trial patients with melanoma brain metastases were randomised to receive WBRT (30 Gy in 10 fractions) plus 3 weeks of concurrent vandetanib 100 mg once daily or placebo. The primary endpoint was progression-free survival in brain (PFS brain). The main study was preceded by a safety run-in phase to confirm tolerability of the combination. A post-hoc analysis and literature review considered barriers to recruiting patients with melanoma brain metastases to clinical trials. RESULTS: Twenty-four patients were recruited, six to the safety phase and 18 to the randomised phase. The study closed early due to poor recruitment. Median PFS brain was 3.3 months (90% confidence interval (CI): 1.6-5.6) in the vandetanib group and 2.5 months (90% CI: 0.2-4.8) in the placebo group (P=0.34). Median overall survival (OS) was 4.6 months (90% CI: 1.6-6.3) and 2.5 months (90% CI: 0.2-7.2), respectively (P=0.54). The most frequent adverse events were fatigue, alopecia, confusion and nausea. The most common barrier to study recruitment was availability of alternative treatments. CONCLUSIONS: The combination of WBRT plus vandetanib was well tolerated. Compared with WBRT alone, there was no significant improvement in PFS brain or OS, although we are unable to provide a definitive result due to poor accrual. A review of barriers to trial accrual identified several factors that affect study recruitment in this difficult disease area. PMID- 27711086 TI - Fournier's gangrene. A clinical review. AB - INTRODUCTION AND HYPOTHESIS: Fournier's gangrene is a rare, necrotising fasciitis of the external genitalia, perineal or perianal regions. The disease has a higher incidence in males and risk factors for development include diabetes, HIV, alcoholism and other immune-compromised states. The aggressive disease process is associated with a high mortality rate of 20-30%. In addition, the increasing age and prevalence of diabetes in the population, begs the need for increased clinical awareness of Fournier's gangrene with emphasis on early diagnosis and management. This review aims to highlight the relevant research surrounding Fournier's gangrene, in particular the various prognostic indicators and management strategies. METHODS: A search was conducted on the MEDLINE database for all applicable research; clinical reviews, retrospective studies and case reports. In addition to which a search of the European Association of Urology, the British Association for Urological Surgeons and the British Medical Journal was conducted for the most recent recommendations. RESULTS: Immediate broad spectrum antibiotic therapy and urgent surgical debridement are the core managerial principles of Fournier's gangrene. The use of adjunctive therapies such as hyperbaric oxygen and vacuum assisted closure are supported in some aspects of the literature and disputed in others. The lack of randomized controlled studies limits the use of these potential additional therapies to patients unresponsive to conventional management. The value of unprocessed honey as a topical antimicrobial agent has been highlighted in the literature for small lesions in uncomplicated patients. CONCLUSION: Fournier's gangrene is a urological emergency with a high mortality rate despite advances in the medical and surgical fields. The aggressive nature of the infection advocates the need for early recognition allowing immediate surgical intervention. The opposing results of available research as well as the lack of high quality evidence surrounding emergent therapies prevents their routine use in the management of Fournier's gangrene. The absence of a specific care pathway may hinder efficient management of Fournier's gangrene, thus based on current guidelines a management pathway is suggested. PMID- 27711085 TI - Cessation of targeted therapy after a complete response in BRAF-mutant advanced melanoma: a case series. AB - BACKGROUND: It is unknown whether melanoma patients achieving complete response (CR) with targeted therapy can safely discontinue treatment. METHODS: All patients treated with BRAF/MEK inhibitors achieving CR and ceasing treatment before progression were identified. Clinical data at treatment initiation, cessation and progression were examined. RESULTS: A total of 12 eligible patients were identified, with median follow-up of 16 months, of whom 6 (50%) recurred at a median of 6.6 months after treatment cessation. One patient lost to follow-up until presentation with symptomatic recurrence was the only relapser to die. At relapse, the remaining five patients had an LDH <1.2 times ULN, four were ECOG 0 and one ECOG 1. Baseline characteristics and time to CR and to discontinuation did not influence the rate of relapse. CONCLUSIONS: A large proportion of patients achieving CR with BRAF/MEK inhibitors relapse after treatment cessation. The optimal treatment duration in such patients is unclear, particularly where alternative treatments are available. PMID- 27711087 TI - Chronic obstructive pulmonary disease (COPD) and erectile dysfunction (ED): Results of the BRED observational study. AB - Most patients with chronic obstructive pulmonary disease (COPD) share many risk factors and similar aetiological agents with erectile dysfunction (ED). Both conditions also cause serious interference with quality of life and sexual relationships. In general, ageing and chronic illness decrease sexual interest, sexual function, and testosterone levels. This observational study included 66 male patients referred to our centre with different grades of COPD. We studied the different correlations between COPD and ED. The data collected from each patient regarded the following features: demographic and social condition; smoking status; clinical status; spirometric measurements. In this group, COPD was diagnosed in 78.8% and ED was present in 83.3% with increased severity in presence of LUTS and nicotinism. PMID- 27711088 TI - A combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts is able to improve sexual quality of life in patient with premature ejaculation. AB - OBJECTIVE: The management of patient affected by premature ejaculation (PE) is nowadays not highly satisfactory. Here, we aimed to evaluate the tolerability and efficacy of a combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts in order to improve sexual quality of life in patients with premature ejaculation. MATERIALS AND METHODS: All patients attending to 5 urological centers from January 2015 to March 2015, due to premature ejaculation were enrolled in this study. At the enrolment visit, all subjects underwent self-administered IIEF-5, Male Sexual Health Questionnaire Ejaculation Disorder (MSHQEjD), PEDT and IELTS (calculated as mean from that perceived by partner and that perceived by patient) and underwent urological visit and laboratory examinations. All patients received one tablet per day of a combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts for 3 months (Group A). After 3 months all patients underwent follow-up visit with the same investigations that have been carried out in the enrolment visit. The results were compared with a cohort of patients enrolled in the same period in another urological center and considered as a control group (Group B). All patients in the control group underwent counseling and sexual behavioral treatment without any pharmacological compound. RESULTS: At the follow up analysis, significant changes in terms of IELT in the Group A (mean difference: 31.90; p < 0.05) at 3 months and versus Group B at the intergroup analysis (mean difference: 30.30; p < 0.05) were reported. In the group A, significant differences from baseline to last follow- up were observed relative to IIEF-5 (mean difference: 1.04; p < 0.05), PEDT (mean difference: -2.57; p < 0.05) and FSH (mean difference: -16.46; p < 0.05). CONCLUSION: In conclusion, patients affected by PE may significantly benefit from oral therapy with a combination of tryptophan, Satureja montana, Tribulus terrestris, Phyllanthus emblica extracts in terms of IELT and PEDT scores improvement. PMID- 27711089 TI - Serenoa repens associated with selenium and lycopene extract and bromelain and methylsulfonylmethane extract are able to improve the efficacy of levofloxacin in chronic bacterial prostatitis patients. AB - OBJECTIVE: To date, the management of patients with chronic bacterial prostatitis (CBP) is not satisfactory, especially in terms of symptoms relief. Here, we evaluated the efficacy and the safety of a combination of serenoa repens, selenium and lycopene extract + bromelain and methylsulfonylmethane extract associated with levofloxacin in patients with CBP. MATERIALS AND METHODS: All patients with clinical and instrumental diagnosis of CBP, admitted to a single Urological Institution from March to June 2015 were enrolled in this phase III study. All enrolled patients were randomized into two groups: Group A received levofloxacin 500 mg o.d. for 14 days associated with lycopene and methylsulfonylmethane; Group B received levofloxacin (500 mg o.d. for 14 days) only. Clinical and microbiological analyses were carried out at the time of admission (T0) and during the followups at 1 month (T1) and 6 months (T2) from the end of the treatment. NIH Chronic Prostatitis Symptom Index (CPSI), International Prostatic Symptom Score (IPSS) and Quality of Well-Being (QoL) questionnaires were used. The main outcome measures were the rate of microbiological cure and the improvement in questionnaire results from baseline at the end of the follow-ups period. RESULTS: Forty patients were enrolled in Group A and 39 in Group B. During the follow-up (T1), we recorded a significant changes in terms of NIH-CPSI and IPSS in Group A (mean difference: 17.6 +/- 2.65; 12.2 +/- 2.33; p < 0.01; p < 0.05, respectively) and versus Group B at the intergroup analysis (mean difference: -9 +/- 1.82; -8.33 +/- 1.71; p < 0.05; p < 0.05, respectively). No differences were reported in terms of microbiological findings between the two groups. At the second follow-up visit (T2), questionnaire results demonstrated statistically significant differences between groups (p < 0.001). One patient in Group A (2.5%) and 7 patients (17.9%) in Group B showed a symptomatic and microbiological recurrence (p = 0.02). CONCLUSIONS: The combination of serenoa repens, selenium, lycopene + bromelain and methylsulfonylmethane extracts improved the clinical efficacy of levofloxacin in patients affected by CBP without the development of side effects. PMID- 27711090 TI - Penile vascular diagnostic categorization using penile duplex Doppler ultrasound: Differences in vascular hemodynamics parameters by differences in anatomic sampling location. AB - OBJECTIVES: In 2013 the International Society for Sexual Medicine(ISSM) published the guidelines regarding the standard operating procedure (SOP) for penile duplex Doppler ultrasound (PDDU). Although ISSM-SOP have given important strides in reducing interobserver variability in PDDU by procedural protocol and parameters these guidelines do not address the anatomic location along the penis at which hemodynamic measurements have to be done. In our opinion a "double sampling" may be interesting to detect the arteriogenic or venogenic nature of the erectile dysfunction (ED). In particular sampling measurements at the "crus" (at the level of the peno-scrotal junction) may be significative for detection of veno occlusive dysfunction (VOD),whereas an evaluation at "mid penis" (1/2 distance between peno-scrotal junction and coronal sulcus), may be useful to diagnose an arterial insufficiency (AI). MATERIAL AND METHODS: We evalued 90 men, mean age 56.3, affected with ED of medium degree, responder to PDE5-I that urdergone to PDDU and also responder after pharmacologic intracavernosal injection (PII)of prostaglandin E1 20 mcg, with rigid erection and normal maintenance. We moreover evalued 90 men in youthful age (mean 35.2), in absence of vascular risk factors, no responder to PDE5-I that undergone to PDDU by PII at high dosage (bimix: prostaglandin E1 20 mcg, papaverine 20 mg). RESULTS: In the first pool the sampling at "mid penis" resulted significative for arterial insuffciency (AI) in 81% (73), in presence of normal or borderline end diastolic velocity (EDV). Sampling at the "crus" resulted negative for VOD in 90% (81). In the second pool, 66.6% (60) resulted responder with rigid erection and normal maintenance in presence of normal hemodynamic parameters: peak systolic velocity (PSV) and end diastolic velocity (EDV) both at the "crus" and at "mid penis" sampling. 33.4% (30) responded with a semirigid erection and manifested a constant deficit of maintenance; at the "crus"and at "mid penis" the hemodynamic arterial parameters resulted normal. At the "crus" the EDV resulted significantly augmented (VOD index) in 96.6% (29); at "mid penis" augmented EDV was founded in 50% (15). CONCLUSIONS: These observational data would be able to confirm the utility of a routinary "double sampling" procedure, at the "crus" and at "md penis", during PDDU in order to better distinguish between VOD or AI or in any case to be useful to stimulate a future more precise standardization in execution of PDDU examination. PMID- 27711091 TI - Testicular prosthesis: Patient satisfaction and sexual dysfunctions in testis cancer survivors. AB - PURPOSE: We studied patient satisfaction about sexual activity after prosthesis implantation using validated questionnaires with the aim to discover if testicular prosthesis could be responsible of sexual dysfunctions (erectile dysfunction or premature ejaculation). MATERIALS AND METHODS: We evaluated a total of 67 men who underwent radical orchiectomy for testicular cancer and a silicon testicular prosthesis implantation from January 2008 to June 2014 at our Hospital. These patients completed 5 validated questionnaires the day before orchiectomy and 6 months after surgery: the International Index of Erectile Function 5 (IIEF5), the Premature Ejaculation Diagnostic Tool (PEDT), the Body Exposure during Sexual Activities Questionnaire (BESAQ), the Body-Esteem Scale and the Rosenberg Self- Esteem Scale. We also evaluated 6 months after surgery any defects of the prosthesis complained by the patients. RESULTS: The questionnaires completed by patients didn't show statistically significant changes for erectile dysfunction (p > 0.05) and premature ejaculation (p > 0.05). On the contrary the psychological questionnaires showed statistically significant change for the BESAQ (p < 0.001) and the Body Esteem Scale (p < 0.001), but not for the Rosenberg Self-Esteem Scale (p > 0,05). A total of 15 patients (22.37%) were dissatisfied about the prosthesis: the most frequent complaint (8 patients; 11.94%) was that the prosthesis was firmer than the normal testis. CONCLUSIONS: Testicular prosthesis implantation is a safe surgical procedure that should be always proposed before orchiectomy for cancer of the testis. The defects complained by patients with testicular prosthesis are few, they don't influence sexual activity and they aren't able to cause erectile dysfunction or premature ejaculation. PMID- 27711092 TI - Explorative surgery for acute scrotal pain: The importance of patient age, side affected, time to surgery and surgeon. AB - INTRODUCTION AND OBJECTIVE: Testicular torsion must be diagnosed quickly and accurately. The delay of the diagnosis and the subsequent delay of surgery may lead to loss testicular viability and orchidectomy. Aim of our retrospective evaluation was to define which element should be considered as major support to the clinician in distinguishing spermatic cord torsion from the other diseases mimicking this clinical emergency requiring surgical exploration. MATERIAL AND METHODS: We retrospectively reviewed all clinical and instrumental data of emergency scrotal exploration performed for acute scrotal pain at two different Urological Department in a 10 year period. Results of surgical exploration represented the four diagnostic categories in which patients were divided for statistical evaluation. We evaluated the relationship between diagnosis performed by testicular surgical exploration and the all clinical data available including surgeon involved in the procedures. RESULTS: A total of 220 explorative scrotal surgery were considered. We divided the cases in 4 categories according to the diagnostic results of each surgical procedure. Of all, spermatic cord torsion was diagnosed in 45% (99/220). The total testis salvage rate was of 78.8%. The patients with a diagnosis of spermatic cord torsion were older than patients with appendix torsion (15 vs 11 years in mean). When the affected side was the left, the probability to have a diagnosis of spermatic cord torsion was higher than the right side [chi2 (2, N = 218) = 11.77, p < 0.01]. Time elapsing between onset of symptoms and testicular salvagewas significantly lower even than in case of appendix torsion/necrosis (p < .0001), and of others pathologies diagnosed (p = .0383). CONCLUSION: In case of spermatic cord torsion, in addition to the clinical data, patient age and left side affected may represent an independent diagnostic predicting factor. The time elapsing between onset of symptoms and explorative surgery remain the only still prognostic factor for testicular viability. PMID- 27711093 TI - In the search of novel urine biomarkers for the early diagnosis of prostate cancer. Intracellular or secreted proteins as the target group? Where and how to search for possible biomarkers useful in the everyday clinical practice. AB - OBJECTIVE: To search which category of proteins can be detected in urine in order to examine subsequently its ability to improve our accuracy for the diagnosis of Prostate Cancer (PCa) as biomarkers in clinical useful fluids like urine and serum. Material and method(s): Urine samples of 127 patients were obtained after a vigorous transrectal prostatic massage to both lobes. The patients were considered to have a high risk for PCa according to their PSA (> 4 ng/ml), their digital rectal examination (DRE) (positive for suspicious prostatic lesions) or to their abnormal PSA kinetics (PSA velocity (PSAV > 0.75 ng/mL). All patients subsequently were subjected to an extended 10-core per prostatic lobe TRUS-b (total 20 prostatic samples). The proteins that were chosen to be detected in the urine samples with Western-blot, as possible biomarkers, were Glutathione peroxidase 3 precursor (GPx3), Cofilin-1 (CFL1), Heat shock protein-90beta (HSP 90beta), Zinc alpha 2-glycoprotein (ZAG) and secreted protein acidic and rich in cysteine (SPARC).These proteins have been detected previously in the prostatic tissue by proteomics proving their discriminative ability between patients with prostate cancer and benign prostatic hyperplasia. RESULT(S): From the five proteins, only the secreted Zinc alpha 2-glycoprotein was detected in urine showing a promising ability in the improvement of our diagnostic accuracy for the early diagnosis of prostate cancer. CONCLUSIONS: From various categories of proteins that have already been detected in the tissue of prostate by proteomics, only secreted protein Zinc alpha 2-glycoprotein showed a clear signal in the urine, proving its discriminative potential for the early diagnosis of PCa. PMID- 27711094 TI - Emergency management of ureteral stones: Evaluation of two different approaches with an emphasis on patients' life quality. AB - OBJECTIVES: To evaluate the emergency management of obstructing ureteral calculi with two different techniques (SWL and URS) with an emphasis on patients life quality. METHODS: A total of 80 patients presenting with acute colic pain due to a single obstructing ureteral stone were treated within 24 hours following the onset of pain with two different approaches in a randomized manner. Patients requiring DJ stent placement and/or auxiliary measures after both procedures were excluded and the remaining 65 patients were evaluated [Group1: ESWL (n = 34); Group 2: URS (n = 31)]. Patients were followed during 4-weeks period with respect to the analgesic requirement, number of renal colic attacks and emergency department visits along with the HRQOL scores. RESULTS: While 26 patients treated with URS (83.9%) were stone-free, 24 cases in SWL were stone-free (70.6%) after 4 weeks. Evaluation of the cases during this follow-up period demonstrated that cases undergoing SWL required significantly higher amount of analgesics when compared with URS group (p < 0.001). In addition to the lower mean number of renal colic attacks and emergency department visits in URS group; both the mean HRQOL in terms of EQ-5D index and mean EQ-5D VAS values were also significantly higher in these cases when compared with the cases tretaed with SWL. CONCLUSIONS: Due to the negative impact of stone related events after emergency SWL on patients HRQOL, emergency URS may be applied more effectively with the advantages of prompt fragmentation of the calculi along with the immediate relief of obstruction and pain. PMID- 27711095 TI - Metabolic evaluation in patients with infected nephrolithiasis: Is it necessary? AB - Fifty-four patients with infected renal lithiasis underwent complete metabolic evaluation searching for underlying factors contributing to stone formation including urine analysis and culture. Metabolic abnormalities were significantly more present in patients with mixed infected stones (struvite+/-apatite and calcium oxalate) than in patients with pure infected stones (struvite+/-carbonate apatite): hypercalciuria in 40%, hyperoxaluria in 34% and hyperuricosuria in 28% (p < 0.05). Urinary excretion of citrate was low in both groups without statistically significant difference (238+/-117 mg/24 h vs 214+/-104 mg/24/h, t = 0.72, p = 0.5). The few metabolic abnormalities present in patients with pure infected stones should suggest that urinary tract infection could change the urine chemistry in a lithogenic direction and be only cause of stone formation. PMID- 27711096 TI - Retrograde intrarenal surgery (RIRS), regular and small sized percutaneous nephrolithotomy (PCNL) in daily practice: European Association of Urology Section of Urolithiasis (EULIS) Survey. AB - OBJECTIVE: A wide selection of both anterograde and retrograde mini-invasive procedures exist for stones' treatment. The 2016 European Association of Urology (EAU) guidelines still don't univocally define a best option. Our purpose is to give an overview on some European Stone Centers' customs and to compare real life clinical practice with statements of opinion leaders and Guidelines. MATERIALS AND METHODS: In 2015 we performed a survey in 3 step about the spread of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) techniques among EAU Section of Urolithiasis (EULIS) members. The 1st and 2nd steps dealt with the definition of EULIS urologist and department by collecting personal opinions about the endoscopic techniques. The third step was about clinical results. This paper presents data from the first two steps. RESULTS: Ninety-one people answered. Out of them, 80% are European and 42% work in Centres fully dedicated to stone treatment. In particular, 50% of responders perform more than 80 RIRS/year, 25% more than 80 PCNL/year, 48% more than 100 extracorporeal shock wave lithotripsy (SWL)/year. RIRS is mainly used to treat stones < 2 cm both as primary treatment and after SWL failure. 73% don't perform routine pre stenting and 66% ordinarily use a ureteral sheath. Hospital stay for RIRS is 24h for 70% of responders. Regular PCNL is performed by 87% of the responders, MiniPCNL by 58%, Ultra-MiniPCNL by 23% and MicroPCNL by 28%. Pneumatic balloon dilation is the favourite dilation technique (49%). 37% of responders perform PCNL always in the supine position, 21% always in the prone one. Almost all the responders agree about using Mini, Ultra-Mini and MicroPCNL for 1-2 cm stones. Approximately 50% also use MiniPCNL for stones > 2 cm. CONCLUSION: our survey confirms the great heterogeneity existing in stones' treatment techniques in daily practice. PMID- 27711097 TI - Chylous ascites as a complication of left sided robot-assisted laparoscopic partial nephrectomy. AB - OBJECTIVE: The aim of the study was to present a case series of the sparsely reported complication of chylous ascites (CA) after left sided robot-assisted laparoscopic partial nephrectomy (RALPN), identify possible risk factors for the development of postoperative CA, and explore current recommendations for identification, management and prevention of CA. MATERIAL AND METHODS: A retrospective review of patients that were treated with a RALPN during a one year time period (August 2012 to August 2013) by one surgeon at our institution was conducted. A total of 12 patients were included in the study. Demographics, tumor characteristics, and perioperative outcomes were assessed. RESULTS: Three patients in the study experienced postoperative CA. All three patients had left sided surgery. The initial clinical suspicion for CA was raised due to complaints of abdominal pain with increased milky appearance of JP fluid. JP triglycerides were elevated in all three patients. The patients responded to conservative measures, with two patients treated with medium chain triglyceride diets and one patient treated with total parenteral nutrition (TPN). Among the patients treated with RALPN, the group that was diagnosed with postoperative CA (CA group) was found to have a statistically significant lower average body mass index (BMI) as compared to the group that did not have CA (non-CA group) (24.67 kg/m2 in the CA group versus 31.77 kg/m2 in the non-CA group; P = 0.026). Other demographic data, tumor characteristics, and perioperative outcomes were similar in both groups. CONCLUSIONS: CA as a result of RALPN is a newly reported and rare postoperative complication. As utilization of RALPN continues to increase, urologists should be aware of this possible complication and be adept at diagnosing and managing CA. We suggest that left sided retroperitoneal surgery and a lower BMI preoperatively be considered risk factors for developing this complication. PMID- 27711098 TI - Bleeding during laparoscopic partial nephrectomy: Can a hemostatic matrix help to improve hemostasis? AB - OBJECTIVES: To evaluate the possible role of an hemostatic matrix on hemostasis, perioperative outcomes and complications in patients who underwent laparoscopic partial nephrectomy (LPN). MATERIALS AND METHODS: Patients charts were analyzed retrospectively and their demographic characteristics, operative parameters and follow-up results were recorded. Patients were divided into two groups, according to those who used an hemostatic matrix as Group 1 (n = 41) and those who did not used as Group 2 (n = 44). Demographic characteristics of patients, tumor features, operation time, clamping of the renal vessels, ischemia time, suturing of the collecting system, perioperative hemorrhage and complications were evaluated. Histopathological results, surgical margin status, creatinine level and recurrence at the 3rd month of follow up were analyzed. Statistical analyses were performed with SPSS 17.0 and significance was set at p value of < 0.05. RESULTS: The mean RENAL nephrometry score was 5.9 +/- 2.0 and the mean tumor size was 35 +/- 12 mm. All patients had a single tumor and 44 of them had a tumor in the right kidney. The renal artery was clamped in 79 cases and the mean ischemia time was 20.1 +/- 7 minutes. The mean tumor size and the mean RENAL nephrometry score was statistically higher in Group 1 (p: 0.016 and p < 0.001, respectively). Pelvicaliceal repair was more common in Group 1 due to deeper extension of tumors in this group (p: 0.038). In Group 1, less hemorrhage and blood transfusion requirement, with shorter ischemia and operation time was detected. CONCLUSION: The outcomes of the recent study showed that adjunctive use of an hemostatic matrix improves hemostasis and decreases hemorrhagic complications during LPN. Further prospective studies are required to assess the potential role of an hemostatic matrix in LPN. PMID- 27711099 TI - Telerounding & telementoring for urological procedures. AB - Telemedicine is the use of medical information exchanged from one site to another via electronic communications to improve a patient's clinical health status. Telemedicine includes a growing variety of applications and services using two way video, email, smart phones, wireless tools and other forms of telecommunications technology. Starting out over forty years ago with demonstrations of hospitals extending care to patients in remote areas, the use of telemedicine has spread rapidly and is now becoming integrated into the ongoing operations of hospitals, specialty departments, home health agencies, private physician offices as well as consumer's homes and workplaces. There's also a current trend in the use of telemedicine in urology. In the present paper we aimed to review the recent literature about telemedicine and the use of telerounding and telementoring in urological procedures. PMID- 27711100 TI - May ultrasound probe size influence pain perception of needle piercing during transrectal prostate biopsy? A prospective evaluation. AB - INTRODUCTION AND OBJECTIVE: Transrectal ultrasound guided prostate biopsy (TRUS Bx) is the definitive step in the diagnosis of prostate cancer (CaP). Patients (pts) generally experience significant pain during the procedure at the point that biopsy should be accompanied by some form of anesthesia. Several different factors influence pain perception (PP) during TRUS-Bx. In our study we want to assess that the use of an ergonomic smaller sized probe reduces PP during the procedure independently from the administration of local anesthesia or pain relieving drugs. MATERIALS AND METHODS: This was a prospective, randomized study in which 114 pts who underwent TRUS-Bx due to abnormal PSA and/or to digital rectal examination (DRE) suspicious findings were considered eligible. Pts were split in two TRUS-Bx groups into which we used two different sized ultrasound probes. In group 1, 61 pts underwent TRUS-Bx with ALOKA end fire probe (size 74 mm). In group 2, 53 pts underwent TRUS-Bx with B-K Type 8818 probe (size 58 mm). Both groups were treated with no local anesthesia or pain relieving drugs. Pain was evaluated three times using a 10-point visual analogue scale (VAS), during the DRE (VAS 1), during the insertion of the probe (VAS 2) and during the needle piercing (VAS 3). RESULTS: Mean age of pts was 68.03 (SD 8.51); mean tPSA and mean prostate volume was 7.75 (SD 4.83) and 45.17cc (SD 17.7), respectively. The two groups were homogeneous respect to tPSA (p = 0.675) and to prostate volume (p = 0.296); age was significantly different (p = 0.04) between Group 1 (65.93) and Group 2 (70.43), whereas no statistically significant correlation between VAS 3 and age was observed (p = 0.179). Analyzing pain perception, we found no statistically significant difference between the two groups in DRE (VAS 1; p = 0.839); on the contrary, patients in Group 1 experienced on average more pain than other in Group 2 both during the insertion of the probe (VAS 2 3.49 vs 1.09; p < 0.001) and during the needle piercing VAS 3 (2.8 vs 2.00; p < 0.05). The discomfort during probe insertion and manipulation was perceived as very high (VAS 2 > 5) in 42.6% of patients in Group 1 and in 9.4% in Group 2. Globally, the procedure was well tolerated (mean VAS score < 3) in 77% of patients in Group 1 and in 90% in Group 2. The proportion of patients who experienced more than moderate pain (VAS > 5) during needle piercing ranged 24.6 % in Group 1 to 18.9 % in Group 2. CONCLUSIONS: Patients who underwent a TRUS-Bx with the 58-mm circumference probe were found to experience lower degree of pain not only during the insertion of the probe through the anal sphincter, but also in the moment of needle piercing. PMID- 27711101 TI - Non sex-related subtotal rupture of the corpus cavernosum without urethral injury: A case report and literature review. AB - Although penile fracture is a rare case, it is a well-described urologic emergency. It results from the rupture of the tunica albuginea of corpora cavernosa by blunt strain that commonly mandates immediate surgical exploration. Urethral injury may also accompany penile fracture. An ideal anamnesis and a special physical examination were determinant to achieve a correct diagnosis. It is usually diagnosed based on clinical examination, but ultrasonography can be very helpful in diagnosis. The treatment is based on the presence of associated urethral injury. Early surgery is preferable to conservative management, because it is associated with better outcomes and fewer long-term complications. The surgical repair of cavernous body can produce good results, with a favorable prognosis and minimal rate of complications. We present a penile fracture case of 34-year-old with subtotal rupture of the right corpus cavernosum without urethral injury who treated by early surgery and good results.

AB - Priapism is a rare clinical condition characterized by a persistent erection unrelated to sexual excitement. Often the etiology is idiopathic. Three cases of priapism in glucose-6-phosphate dehydrogenase (G6PD) deficiency patients have been described in literature. We present the case of a 39-year-old man with glucose- 6-phosphate dehydrogenase deficiency, who reached out to our department for the arising of a non-ischemic priapism without arteriolacunar fistula. We suggest that the glucose-6-phosphate dehydrogenase deficiency could be an underestimated risk factor for priapism.

AB - Fournier's gangrene is a life-threatening acute necrotizing fasciitis of perianal,genitourinary and perineal areas. Nowadays, is well known that Fournier gangrene is almost never an idiopathic disease. In this article we report a case of a 70-year-old patient that initially was not treated properly. The gold standard therapy of the Fournier's gangrene remains today a complete, early and extended surgical debridement.

AB - Penile augmentation has been reported in the literature by injecting various materials. This study reports our experience in management of penile augmentation complications associated with selfpenile injection of silicone liquid. After a careful ultrasound study, the penile skin was excised through a circumferential sub-coronal incision and dissected with the silicon mass. Histology was well compatible with silicone granulomas. The patient was discharged after 24 hours. Ultrasonography has permitted preoperatively to determine if the plane between the indurated inflammatory tissue and the Buck's fascia was preserved for the complete surgical excision of affected tissue. PMID- 27711105 TI - Adenomatous hyperplasia of the rete testis: A rare intrascrotal lesion managed with limited testicular excision. AB - INTRODUCTION: Testicular cancer is one of the most frequent in young men and its incidence is increasing in recent years because of incidental finding during routine ultrasound exams. Adenomatous hyperplasia of the rete testis is one of the benign and rare pathological types incidentally detected and very few cases are described in the literature. CASE REPORT: A 40 years old man come to our attention for a balanoposthitis without testicular pain. During andrological examination we performed palpation of the testes and we noticed a palpable nodule of hard consistency in the left testicle. We then performed an ultrasound exam of the testis which highlighted the presence of an intra-didymus neoformation with diameters of 1.2 x 1.6 cm and with the presence of cysts inside. We also performed blood tests to check tumor markers alpha fetoprotein, beta hCG and LDH which resulted inside the normal range. We then conducted a chest and abdomen CT scan that showed no pathological elements. Therefore, as we suspected that this tumor was benign, we performed an enucleation of the neoplasm. The definitive histological examination revealed the presence of dilated ducts lined with epithelial cubic-columnar cells with clear cytoplasm rich in glycogen and the pathologist so concluded that the tumor could be classified as adenomatous hyperplasia of the rete testis. At three months of follow up, the patient doesn't have any recurrent lesion to either testicles. DISCUSSION: Adenomatous hyperplasia of the rete testis is a very rare intrascrotal lesion. This histological type is the most frequent between benign lesion of the ovary, but few works in literature reported this histological type in the male gonad and, in most of these works, authors described these lesion at epididymis. CONCLUSION: We believe that a conservative approach must be considered mandatory in case of testicular lesions 1.5 cm in diameter. A radical approach might have alterate fertility of the patient and also have caused psychological trauma more than an enucleation. However a longer follow up is needed to understand if this was the right decision for the oncological point of view. PMID- 27711106 TI - A rubber tube in the bladder as a complication of autoerotic stimulation of the urethra. AB - Self-insertion of foreign bodies in the urethra is most commonly associated with sexual or erotic arousal of adolescents with mental health disorders. Rarely it may practiced by healthy adults for masturbation. Migration of foreign bodies used for the abovementioned purpose from the urethra to adjacent organs is a relatively uncommon urologic problem that may cause serious complications which arose tardive. Presentation includes a variety of acute or chronic symptoms that depend of the underlying complications. The method of extraction depends on the shape, size and nature of the object and should be tailored according to the condition of the patient. In the present article we present a case of a rubber tube inserted to the urethra for erotic arousal purposes which migrated to the bladder during masturbation. PMID- 27711107 TI - Primary pure carcinoid tumour of the testis: A case report and review of the literature. AB - Primary testicular carcinoid tumours (TCT) are very rare, and a large tumour size and the presence of carcinoid syndrome predict a malignant course. Histologically, it is difficult to differentiate between benign and malignant TCTs. We report a case of a primary pure TCT with an unusual presentation in a 23 year-old man, who had an asymptomatic, enlarged scrotum on the right side for 7 years. On gross examination, the tumour was 9.6 cm in diameter. The Ki-67 labelling index was 19.8%. High inguinal orchidectomy was performed, and 30 months after surgery the patient remains asymptomatic. PMID- 27711108 TI - Mechanistic Insight into the Host Transcription Inhibition Function of Rift Valley Fever Virus NSs and Its Importance in Virulence. AB - Rift Valley fever virus (RVFV), a member of the genus Phlebovirus within the family Bunyaviridae, causes periodic outbreaks in livestocks and humans in countries of the African continent and Middle East. RVFV NSs protein, a nonstructural protein, is a major virulence factor that exhibits several important biological properties. These include suppression of general transcription, inhibition of IFN-beta promoter induction and degradation of double-stranded RNA-dependent protein kinase R. Although each of these biological functions of NSs are considered important for countering the antiviral response in the host, the individual contributions of these functions towards RVFV virulence remains unclear. To examine this, we generated two RVFV MP-12 strain derived mutant viruses. Each carried mutations in NSs that specifically targeted its general transcription inhibition function without affecting its ability to degrade PKR and inhibit IFN-beta promoter induction, through its interaction with Sin3-associated protein 30, a part of the repressor complex at the IFN-beta promoter. Using these mutant viruses, we have dissected the transcription inhibition function of NSs and examined its importance in RVFV virulence. Both NSs mutant viruses exhibited a differentially impaired ability to inhibit host transcription when compared with MP-12. It has been reported that NSs suppresses general transcription by interfering with the formation of the transcription factor IIH complex, through the degradation of the p62 subunit and sequestration of the p44 subunit. Our study results lead us to suggest that the ability of NSs to induce p62 degradation is the major contributor to its general transcription inhibition property, whereas its interaction with p44 may not play a significant role in this function. Importantly, RVFV MP-12-NSs mutant viruses with an impaired general transcription inhibition function showed a reduced cytotoxicity in cell culture and attenuated virulence in young mice, compared with its parental virus MP-12, highlighting the contribution of NSs-mediated general transcription inhibition towards RVFV virulence.

PMID- 27711110 TI - Stoichiometric Representation of Gene-Protein-Reaction Associations Leverages Constraint-Based Analysis from Reaction to Gene-Level Phenotype Prediction. AB - Genome-scale metabolic reconstructions are currently available for hundreds of organisms. Constraint-based modeling enables the analysis of the phenotypic landscape of these organisms, predicting the response to genetic and environmental perturbations. However, since constraint-based models can only describe the metabolic phenotype at the reaction level, understanding the mechanistic link between genotype and phenotype is still hampered by the complexity of gene-protein-reaction associations. We implement a model transformation that enables constraint-based methods to be applied at the gene level by explicitly accounting for the individual fluxes of enzymes (and subunits) encoded by each gene. We show how this can be applied to different kinds of constraint-based analysis: flux distribution prediction, gene essentiality analysis, random flux sampling, elementary mode analysis, transcriptomics data integration, and rational strain design. In each case we demonstrate how this approach can lead to improved phenotype predictions and a deeper understanding of the genotype-to-phenotype link. In particular, we show that a large fraction of reaction-based designs obtained by current strain design methods are not actually feasible, and show how our approach allows using the same methods to obtain feasible gene-based designs. We also show, by extensive comparison with experimental 13C-flux data, how simple reformulations of different simulation methods with gene-wise objective functions result in improved prediction accuracy. The model transformation proposed in this work enables existing constraint-based methods to be used at the gene level without modification. This automatically leverages phenotype analysis from reaction to gene level, improving the biological insight that can be obtained from genome scale models. PMID- 27711111 TI - The Electrophysiology of Basic Phrase Building. AB - A defining trait of linguistic competence is the ability to combine elements into increasingly complex structures to denote, and to comprehend, a potentially infinite number of meanings. Recent magnetoencephalography (MEG) work has investigated these processes by comparing the response to nouns in combinatorial (blue car) and non-combinatorial (rnsh car) contexts. In the current study we extended this paradigm using electroencephalography (EEG) to dissociate the role of semantic content from phonological well-formedness (yerl car). We used event related potential (ERP) recordings in order to better relate the observed neurophysiological correlates of basic combinatorial operations to prior ERP work on comprehension. We found that nouns in combinatorial contexts (blue car) elicited a greater centro-parietal negativity between 180-400ms, independent of the phonological well-formedness of the context word. We discuss the potential relationship between this 'combinatorial' effect and classic N400 effects. We also report preliminary evidence for an early anterior negative deflection immediately preceding the critical noun in combinatorial contexts, which we tentatively interpret as an electrophysiological reflex of syntactic structure initialization. PMID- 27711112 TI - Chromosomal Replication Complexity: A Novel DNA Metrics and Genome Instability Factor. AB - As the ratio of the copy number of the most replicated to the unreplicated regions in the same chromosome, the definition of chromosomal replication complexity (CRC) appears to leave little room for variation, being either two during S-phase or one otherwise. However, bacteria dividing faster than they replicate their chromosome spike CRC to four and even eight. A recent experimental inquiry about the limits of CRC in Escherichia coli revealed two major reasons to avoid elevating it further: (i) increased chromosomal fragmentation and (ii) complications with subsequent double-strand break repair. Remarkably, examples of stable elevated CRC in eukaryotic chromosomes are well known under various terms like "differential replication," "underreplication," "DNA puffs," "onion-skin replication," or "re-replication" and highlight the phenomenon of static replication fork (sRF). To accurately describe the resulting "amplification by overinitiation," I propose a new term: "replification" (subchromosomal overreplication). In both prokaryotes and eukaryotes, replification, via sRF processing, causes double-strand DNA breaks and, with their repair elevating chromosomal rearrangements, represents a novel genome instability factor. I suggest how static replication bubbles could be stabilized and speculate that some tandem duplications represent such persistent static bubbles. Moreover, I propose how static replication bubbles could be transformed into tandem duplications, double minutes, or inverted triplications. Possible experimental tests of these models are discussed. PMID- 27711113 TI - MiR-155 Enhances Insulin Sensitivity by Coordinated Regulation of Multiple Genes in Mice. AB - miR-155 plays critical roles in numerous physiological and pathological processes, however, its function in the regulation of blood glucose homeostasis and insulin sensitivity and underlying mechanisms remain unknown. Here, we reveal that miR-155 levels are downregulated in serum from type 2 diabetes (T2D) patients, suggesting that miR-155 might be involved in blood glucose control and diabetes. Gain-of-function and loss-of-function studies in mice demonstrate that miR-155 has no effects on the pancreatic beta-cell proliferation and function. Global transgenic overexpression of miR-155 in mice leads to hypoglycaemia, improved glucose tolerance and insulin sensitivity. Conversely, miR-155 deficiency in mice causes hyperglycemia, impaired glucose tolerance and insulin resistance. In addition, consistent with a positive regulatory role of miR-155 in glucose metabolism, miR-155 positively modulates glucose uptake in all cell types examined, while mice overexpressing miR-155 transgene show enhanced glycolysis, and insulin-stimulated AKT and IRS-1 phosphorylation in liver, adipose tissue or skeletal muscle. Furthermore, we reveal these aforementioned phenomena occur, at least partially, through miR-155-mediated repression of important negative regulators (i.e. C/EBPbeta, HDAC4 and SOCS1) of insulin signaling. Taken together, these findings demonstrate, for the first time, that miR-155 is a positive regulator of insulin sensitivity with potential applications for diabetes treatment. PMID- 27711114 TI - Muscle MRI Findings in Childhood/Adult Onset Pompe Disease Correlate with Muscle Function. AB - OBJECTIVES: Enzyme replacement therapy has shown to be effective for childhood/adult onset Pompe disease (AOPD). The discovery of biomarkers useful for monitoring disease progression is one of the priority research topics in Pompe disease. Muscle MRI could be one possible test but the correlation between muscle MRI and muscle strength and function has been only partially addressed so far. METHODS: We studied 34 AOPD patients using functional scales (Manual Research Council scale, hand held myometry, 6 minutes walking test, timed to up and go test, time to climb up and down 4 steps, time to walk 10 meters and Motor Function Measure 20 Scale), respiratory tests (Forced Vital Capacity seated and lying, Maximun Inspiratory Pressure and Maximum Expiratory Pressure), daily live activities scales (Activlim) and quality of life scales (Short Form-36 and Individualized Neuromuscular Quality of Life questionnaire). We performed a whole body muscle MRI using T1w and 3-point Dixon imaging centered on thighs and lower trunk region. RESULTS: T1w whole body muscle MRI showed a homogeneous pattern of muscle involvement that could also be found in pre-symptomatic individuals. We found a strong correlation between muscle strength, muscle functional scales and the degree of muscle fatty replacement in muscle MRI analyzed using T1w and 3 point Dixon imaging studies. Moreover, muscle MRI detected mild degree of fatty replacement in paraspinal muscles in pre-symptomatic patients. CONCLUSION: Based on our findings, we consider that muscle MRI correlates with muscle function in patients with AOPD and could be useful for diagnosis and follow-up in pre symptomatic and symptomatic patients under treatment. TAKE HOME MESSAGE: Muscle MRI correlates with muscle function in patients with AOPD and could be useful to follow-up patients in daily clinic. PMID- 27711116 TI - Pressure Infusion Cuff and Blood Warmer during Massive Transfusion: An Experimental Study About Hemolysis and Hypothermia. AB - BACKGROUND: Blood warmers were developed to reduce the risk of hypothermia associated with the infusion of cold blood products. During massive transfusion, these devices are used with compression sleeve, which induce a major stress to red blood cells. In this setting, the combination of blood warmer and compression sleeve could generate hemolysis and harm the patient. We conducted this study to compare the impact of different pressure rates on the hemolysis of packed red blood cells and on the outlet temperature when a blood warmer set at 41.5 degrees C is used. METHODS: Pressure rates tested were 150 and 300 mmHg. Ten packed red blood cells units were provided by Hema-Quebec and each unit was sequentially tested. RESULTS: We found no increase in hemolysis either at 150 or 300 mmHg. By cons, we found that the blood warmer was not effective at warming the red blood cells at the specified temperature. At 150 mmHg, the outlet temperature reached 37.1 degrees C and at 300 mmHg, the temperature was 33.7 degrees C. CONCLUSION: To use a blood warmer set at 41.5 degrees C in conjunction with a compression sleeve at 150 or 300 mmHg does not generate hemolysis. At 300 mmHg a blood warmer set at 41.5 degrees C does not totally avoid a risk of hypothermia. PMID- 27711115 TI - Potency Biomarker Signature Genes from Multiparametric Osteogenesis Assays: Will cGMP Human Bone Marrow Mesenchymal Stromal Cells Make Bone? AB - In skeletal regeneration approaches using human bone marrow derived mesenchymal stromal cells (hBM-MSC), functional evaluation before implantation has traditionally used biomarkers identified using fetal bovine serum-based osteogenic induction media and time courses of at least two weeks. However, emerging pre-clinical evidence indicates donor-dependent discrepancies between these ex vivo measurements and the ability to form bone, calling for improved tests. Therefore, we adopted a multiparametric approach aiming to generate an osteogenic potency assay with improved correlation. hBM-MSC populations from six donors, each expanded under clinical-grade (cGMP) conditions, showed heterogeneity for ex vivo growth response, mineralization and bone-forming ability in a murine xenograft assay. A subset of literature-based biomarker genes was reproducibly upregulated to a significant extent across all populations as cells responded to two different osteogenic induction media. These 12 biomarkers were also measurable in a one-week assay, befitting clinical cell expansion time frames and cGMP growth conditions. They were selected for further challenge using a combinatorial approach aimed at determining ex vivo and in vivo consistency. We identified five globally relevant osteogenic signature genes, notably TGF-beta1 pathway interactors; ALPL, COL1A2, DCN, ELN and RUNX2. Used in agglomerative cluster analysis, they correctly grouped the bone-forming cell populations as distinct. Although donor #6 cells were correlation slope outliers, they contrastingly formed bone without showing ex vivo mineralization. Mathematical expression level normalization of the most discrepantly upregulated signature gene COL1A2, sufficed to cluster donor #6 with the bone-forming classification. Moreover, attenuating factors causing genuine COL1A2 gene down-regulation, restored ex vivo mineralization. This suggested that the signature gene had an osteogenically influential role; nonetheless no single biomarker was fully deterministic whereas all five signature genes together led to accurate cluster analysis. We show proof of principle for an osteogenic potency assay providing early characterization of primary cGMP-hBM-MSC cultures according to their donor specific bone-forming potential. PMID- 27711117 TI - De novo Analysis of the Epiphytic Transcriptome of the Cucurbit Powdery Mildew Fungus Podosphaera xanthii and Identification of Candidate Secreted Effector Proteins. AB - The cucurbit powdery mildew fungus Podosphaera xanthii is a major limiting factor for cucurbit production worldwide. Despite the fungus's agronomic and economic importance, very little is known about fundamental aspects of P. xanthii biology, such as obligate biotrophy or pathogenesis. To design more durable control strategies, genomic information about P. xanthii is needed. Powdery mildews are fungal pathogens with large genomes compared with those of other fungi, which contain vast amounts of repetitive DNA sequences, much of which is composed of retrotransposons. To reduce genome complexity, in this work we aimed to obtain and analyse the epiphytic transcriptome of P. xanthii as a starting point for genomic research. Total RNA was isolated from epiphytic fungal material, and the corresponding cDNA library was sequenced using a 454 GS FLX platform. Over 676,562 reads were obtained and assembled into 37,241 contigs. Annotation data identified 8,798 putative genes with different orthologues. As described for other powdery mildew fungi, a similar set of missing core ascomycete genes was found, which may explain obligate biotrophy. To gain insight into the plant pathogen relationships, special attention was focused on the analysis of the secretome. After this analysis, 137 putative secreted proteins were identified, including 53 candidate secreted effector proteins (CSEPs). Consistent with a putative role in pathogenesis, the expression profile observed for some of these CSEPs showed expression maxima at the beginning of the infection process at 24 h after inoculation, when the primary appressoria are mostly formed. Our data mark the onset of genomics research into this very important pathogen of cucurbits and shed some light on the intimate relationship between this pathogen and its host plant. PMID- 27711118 TI - A Gram Stain Hands-On Workshop Enhances First Year Medical Students' Technique Competency in Comprehension and Memorization. AB - BACKGROUND: Laboratory diagnostic tests have an essential role in patient care, and the increasing number of medical and health professions schools focusing on teaching laboratory medicine to pre-clinical students reflects this importance. However, data validating the pedagogical methods that best influence students' comprehension and interpretation of diagnostic tests have not been well described. The Gram stain is a simple yet significant and frequently used diagnostic test in the clinical setting that helps classify bacteria into two major groups, Gram positive and negative, based on their cell wall structure. METHODS AND FINDINGS: We used this technique to assess which educational strategies may improve students' learning and competency in medical diagnostic techniques. Hence, in this randomized controlled study, we compared the effectiveness of several educational strategies (e.g. workshop, discussion, or lecture) in first year medical students' competency in comprehension and interpretation of the Gram stain procedure. We demonstrated that a hands-on practical workshop significantly enhances students' competency in memorization and overall comprehension of the technique. Interestingly, most students irrespective of their cohort showed difficulty in answering Gram stain-related analytical questions, suggesting that more emphasis should be allocated by the instructors to clearly explain the interpretation of the diagnostic test results to students in medical and health professional schools. CONCLUSION: This proof of principle study highlights the need of practical experiences on laboratory medical techniques during pre-clinical training to facilitate future medical doctors' and healthcare professionals' basic understanding and competency in diagnostic testing for better patient care. PMID- 27711119 TI - Clinical and Wear Analyses of 9 Large Metal-on-Metal Total Hip Prostheses. AB - BACKGROUND: Metal-on-Metal (MoM) total hip arthroplasties (THA) are associated with pseudotumor formation and high revision rates. This prospective study analysed the clinical and wear analyses of 9 large Metal-on-Metal (MoM) total hip arthroplasties (THA) to understand the underlying mechanisms of failure. The MoM bearings were revised for multiple reasons; the main reason was pseudotumor formation. MATERIALS AND METHODS: From 2006 till 2010 the Reinier de Graaf Hospital implanted 160 large head M2a-MagnumTM (Biomet Inc. Warsaw, Indiana, USA) THAs in 150 patients. The first year, 9 bearings were revised and analysed at the Biomechanics Section, Hamburg University of Technology, Germany. We performed clinical (Harris Hip Score, radiographic analysis, blood cobalt and chromium) and wear analysis (implant, tissue and fluid) of the 9 bearings. Since this study did not fall under the scope of the Medical Research Involving Human Subjects Act in The Netherlands, no ethical approval was necessary. In this prospective study all patient details were anonymized by the corresponding author, all other authors were blinded during the research and wear analyses. Patients with bilateral MoM implants were excluded. RESULTS: The 9 bearings had a median (IQR) survival of 41.0 (25) months in situ. From these bearings, three showed no noticeable wear. The median (IQR) head wear volume was 3.2 (3.6) mm3 and maximum wear depth 0.02 (0.02) mm. For the cup the median (IQR) wear volume was 0.23 (0.3) mm3 with a maximum wear depth of 0.03 (0.05) mm. CONCLUSION: An early identification of parameters related to failure of the MoM THA, such as pain, decreased range of motion, radiographic changes and high levels of blood cobalt and chromium is of great importance for patient's quality of life. Especially now patients and surgeons face the long term effects of all these bearings still in situ. This study reports the clinical and wear analyses of 9 MoM THA. In the majority of this group the reason for revision was pseudotumor formation. Most bearings showed signs of wear, however with a great diversity in clinical analysis, in inclination angle, serum cobalt and chromium levels as well as wear analysis. For a better understanding of the underlying mechanisms related with failure, more wear analyses of revised MoM bearings are necessary as well as a frequent follow up of the patients with a MoM bearing. PMID- 27711120 TI - Development and Validation of a Photographic Method to Use for Dietary Assessment in School Settings. AB - OBJECTIVE: To develop and validate a photographic method aimed at making assessment of dietary intake in school canteens non-obstrusive, practical and feasible. METHODS: The study was conducted in two elementary schools representing two different school canteen systems; main dish being served by canteen staff (Iceland), and complete self-serving (Sweden). Food items in serving and leftovers were weighed and photographed. Trained researchers estimated weights of food items by viewing the photographs and comparing them with pictures of half and full reference portions with known weights. Plates of servings and leftovers from 48 children during five school days (n = 448 plates) and a total of 5967 food items were estimated. The researchers' estimates were then compared with the true weight of the foods and the energy content calculated. RESULTS: Weighed and estimated amounts correlated across meals both in grams and as total energy (0.853-0.977, p<0.001). The agreement between estimated energy content in school meals was close to the true measurement from weighed records; on average 4-19 kcal below true values. Organisation of meal service impacted the efficacy of the method as seen in the difference between countries; with Iceland (served by canteen staff) having higher rate of acceptable estimates than Sweden (self serving), being 95% vs 73% for total amount (g) in serving. Iceland more often had serving size between or above the half and full reference plates compared with Sweden. CONCLUSIONS: The photographic method provides acceptable estimates of food and energy intake in school canteens. However, greater accuracy can be expected when foods are served by canteen staff compared with self-serving. PMID- 27711122 TI - Prevalence of Drug Resistance Mycobacterium Tuberculosis among Patients Seen in Coast Provincial General Hospital, Mombasa, Kenya. AB - BACKGROUND: Although prevention and control of spread of multi-drug resistant tuberculosis strains is a global challenge, there is paucity of data on the prevalence of DR-TB in patients diagnosed with TB in referral hospitals in Kenya. The present study assessed patients' characteristics and prevalence of drug resistant TB in sputa smear positive TB patients presenting to Coast Provincial General Hospital (CPGH) in Mombasa, Kenya. METHODS: Drug resistance was evaluated in 258 randomly selected sputa smear TB positive cases between the periods of November 2011 to February 2012 at the CPGH-Mombasa. Basic demographic data was obtained using administered questionnaires, and clinical history extracted from the files. For laboratory analyses, 2mls of sputum was obtained, decontaminated and subjected to mycobacteria DNA analyses. Detection of first line drug resistance genes was done using MDRTDR plus kit. This was followed with random selection of 83 cases for second line drug resistance genes testing using Genotype MDRTBsl probe assay kit (HAINS Lifesciences, GmbH, Germany), in which ethambutol mutation probes were included. The data was then analyzed using SPSS statistical package version 19.0. RESULTS: Male to female ratio was 1:2. Age range was 9 to 75 years, with median of 30 years. New treatment cases constituted 253(98%), among which seven turned out to be PTB negative, and further grouped as 4 (1.6%) PTB negative and 3(1.1%) NTM. 237(91.7%) new cases were fully susceptible to INH and RIF. The remaining, 8 (3.1%) and 1(0.4%) had mono- resistance to INH and RIF, respectively. All the retreatment cases were fully susceptible to the first line drugs. HIV positivity was found in 48 (18.6%) cases, of which 46(17.8%) were co-infected with TB. Of these, 44 (17.1%) showed full susceptibility to TB drugs, while 2 (0.8%) were INH resistant. For the second line drugs, one case each showed mono resistance to both and FQ. Also, one case each showed drug cross poly resistance to both ETH and FQ, with second line injectable antibiotics. However, no significant statistical correlation was established between TB and resistance to the second line drugs p = 0.855. CONCLUSION: The findings of this study showed the existence of resistance to both first and second line anti-tubercular drugs, but no MDR-TB and XDR-TB was detected among patients attending TB clinic at CPGH using molecular techniques. PMID- 27711121 TI - Identification of OmpA-Like Protein of Tannerella forsythia as an O-Linked Glycoprotein and Its Binding Capability to Lectins. AB - Bacterial glycoproteins are associated with physiological and pathogenic functions of bacteria. It remains unclear whether bacterial glycoproteins can bind to specific classes of lectins expressed on host cells. Tannerella forsythia is a gram-negative oral anaerobe that contributes to the development of periodontitis. In this study, we aimed to find lectin-binding glycoproteins in T. forsythia. We performed affinity chromatography of wheat germ agglutinin, which binds to N-acetylglucosamine (GlcNAc) and sialic acid (Sia), and identified OmpA like protein as the glycoprotein that has the highest affinity. Mass spectrometry revealed that OmpA-like protein contains O-type N-acetylhexosamine and hexose. Fluorometry quantitatively showed that OmpA-like protein contains Sia. OmpA-like protein was found to bind to lectins including E-selectin, P-selectin, L selectin, Siglec-5, Siglec-9, Siglec-10, and DC-SIGN. The binding of OmpA-like protein to these lectins, except for the Siglecs, depends on the presence of calcium. N-acetylneuraminic acid (NeuAc), which is the most abundant Sia, inhibited the binding of OmpA-like protein to all of these lectins, whereas GlcNAc and mannose only inhibited the binding to DC-SIGN. We further found that T. forsythia adhered to human oral epithelial cells, which express E-selectin and P-selectin, and that this adhesion was inhibited by addition of NeuAc. Moreover, adhesion of an OmpA-like protein-deficient T. forsythia strain to the cells was reduced compared to that of the wild-type strain. Our findings indicate that OmpA like protein of T. forsythia contains O-linked sugar chains that can mediate interactions with specific lectins. This interaction is suggested to facilitate adhesion of T. forsythia to the surface of host cells. PMID- 27711123 TI - Language-Agnostic Reproducible Data Analysis Using Literate Programming. AB - A modern biomedical research project can easily contain hundreds of analysis steps and lack of reproducibility of the analyses has been recognized as a severe issue. While thorough documentation enables reproducibility, the number of analysis programs used can be so large that in reality reproducibility cannot be easily achieved. Literate programming is an approach to present computer programs to human readers. The code is rearranged to follow the logic of the program, and to explain that logic in a natural language. The code executed by the computer is extracted from the literate source code. As such, literate programming is an ideal formalism for systematizing analysis steps in biomedical research. We have developed the reproducible computing tool Lir (literate, reproducible computing) that allows a tool-agnostic approach to biomedical data analysis. We demonstrate the utility of Lir by applying it to a case study. Our aim was to investigate the role of endosomal trafficking regulators to the progression of breast cancer. In this analysis, a variety of tools were combined to interpret the available data: a relational database, standard command-line tools, and a statistical computing environment. The analysis revealed that the lipid transport related genes LAPTM4B and NDRG1 are coamplified in breast cancer patients, and identified genes potentially cooperating with LAPTM4B in breast cancer progression. Our case study demonstrates that with Lir, an array of tools can be combined in the same data analysis to improve efficiency, reproducibility, and ease of understanding. Lir is an open-source software available at github.com/borisvassilev/lir. PMID- 27711124 TI - Resources Required for Cervical Cancer Prevention in Low- and Middle-Income Countries. AB - BACKGROUND: Cervical cancer is the fourth leading cause of cancer death in women, with 85% of cases and deaths occurring in developing countries. While organized screening programs have reduced cervical cancer incidence in high-income countries through detection and treatment of precancerous lesions, the implementation of organized screening has not been effective in low-resource settings due to lack of infrastructure and limited budgets. Our objective was to estimate the cost of comprehensive primary and secondary cervical cancer prevention in low- and middle-income countries. METHODS AND FINDINGS: We performed a modeling analysis to estimate 1) for girls aged 10 years, the cost of 2-dose human papillomavirus (HPV) vaccination; and 2) for women aged 30 to 49 years, the cost of cervical cancer screening (with visual inspection with acetic acid (VIA), HPV testing, or cytology) and preventive treatment in 102 low- and middle-income countries from 2015 to 2024. We used an Excel-based costing and service utilization model to estimate financial costs (2013 US$) based on prevalence of HPV, prevalence of precancerous lesions, and screening test performance. Where epidemiologic data were unavailable, we extrapolated from settings with data using an individual-based microsimulation model of cervical carcinogenesis (calibrated to 20 settings) and multivariate regression. Total HPV vaccination costs ranged from US$8.6 billion to US$24.2 billion for all scenarios considered (immediate, 5-year, or 10-year roll-out; price per dose US$4.55-US$70 by country income level). The total cost of screening and preventive treatment ranged from US$5.1 billion (10-year roll-out, screening once at age 35 years) to US$42.3 billion (immediate roll-out, high intensity screening). Limitations of this analysis include the assumption of standardized protocols by country income level that did not account for the potential presence of multiple screening modalities or management strategies within a country, and extrapolation of cost and epidemiologic data to settings where data were limited. CONCLUSIONS: The estimated cost of comprehensive cervical cancer prevention with 2-dose HPV vaccination of 10-year-old girls and screening of women aged 30 to 49 years ranges from US$13.7 billion to US$66.5 billion, depending on speed of roll-out, vaccine price per dose, and screening test and frequency. Findings demonstrate the substantial impact of vaccine price in middle-income countries that are not eligible for assistance from Gavi, the Vaccine Alliance. Replacing routine cytology with HPV-based screening may reduce total costs. Data on the health impact and relative cost-effectiveness of strategies are needed to determine the best value for public health dollars. PMID- 27711125 TI - Memory Distortion and Its Avoidance: An Event-Related Potentials Study on False Recognition and Correct Rejection. AB - Memory researchers have long been captivated by the nature of memory distortions and have made efforts to identify the neural correlates of true and false memories. However, the underlying mechanisms of avoiding false memories by correctly rejecting related lures remains underexplored. In this study, we employed a variant of the Deese/Roediger-McDermott paradigm to explore neural signatures of committing and avoiding false memories. ERP were obtained for True recognition, False recognition, Correct rejection of new items, and, more importantly, Correct rejection of related lures. With these ERP data, early frontal, left-parietal, and late right-frontal old/new effects (associated with familiarity, recollection, and monitoring processes, respectively) were analysed. Results indicated that there were similar patterns for True and False recognition in all three old/new effects analysed in our study. Also, False recognition and Correct rejection of related lures activities seemed to share common underlying familiarity-based processes. The ERP similarities between False recognition and Correct rejection of related lures disappeared when recollection processes were examined because only False recognition presented a parietal old/new effect. This finding supported the view that actual false recollections underlie false memories, providing evidence consistent with previous behavioural research and with most ERP and neuroimaging studies. Later, with the onset of monitoring processes, False recognition and Correct rejection of related lures waveforms presented, again, clearly dissociated patterns. Specifically, False recognition and True recognition showed more positive going patterns than Correct rejection of related lures signal and Correct rejection of new items signature. Since False recognition and Correct rejection of related lures triggered familiarity recognition processes, our results suggest that deciding which items are studied is based more on recollection processes, which are later supported by monitoring processes. Results are discussed in terms of Activation-Monitoring Framework and Fuzzy Trace-Theory, the most prominent explanatory theories of false memory raised with the Deese/Roediger-McDermott paradigm. PMID- 27711127 TI - Influencing Busy People in a Social Network. AB - We identify influential early adopters in a social network, where individuals are resource constrained, to maximize the spread of multiple, costly behaviors. A solution to this problem is especially important for viral marketing. The problem of maximizing influence in a social network is challenging since it is computationally intractable. We make three contributions. First, we propose a new model of collective behavior that incorporates individual intent, knowledge of neighbors actions and resource constraints. Second, we show that the multiple behavior influence maximization is NP-hard. Furthermore, we show that the problem is submodular, implying the existence of a greedy solution that approximates the optimal solution to within a constant. However, since the greedy algorithm is expensive for large networks, we propose efficient heuristics to identify the influential individuals, including heuristics to assign behaviors to the different early adopters. We test our approach on synthetic and real-world topologies with excellent results. We evaluate the effectiveness under three metrics: unique number of participants, total number of active behaviors and network resource utilization. Our heuristics produce 15-51% increase in expected resource utilization over the naive approach. PMID- 27711126 TI - Integrated Left Ventricular Global Transcriptome and Proteome Profiling in Human End-Stage Dilated Cardiomyopathy. AB - AIMS: The disease pathways leading to idiopathic dilated cardiomyopathy (DCM) are still elusive. The present study investigated integrated global transcriptional and translational changes in human DCM for disease biomarker discovery. METHODS: We used identical myocardial tissues from five DCM hearts compared to five non failing (NF) donor hearts for both transcriptome profiling using the ABI high density oligonucleotide microarrays and proteome expression with One-Dimensional Nano Acquity liquid chromatography coupled with tandem mass spectrometry on the Synapt G2 system. RESULTS: We identified 1262 differentially expressed genes (DEGs) and 269 proteins (DEPs) between DCM cases and healthy controls. Among the most significantly upregulated (>5-fold) proteins were GRK5, APOA2, IGHG3, ANXA6, HSP90AA1, and ATP5C1 (p< 0.01). On the other hand, the most significantly downregulated proteins were GSTM5, COX17, CAV1 and ANXA3. At least ten entities were concomitantly upregulated on the two analysis platforms: GOT1, ALDH4A1, PDHB, BDH1, SLC2A11, HSP90AA1, HSP90AB1, H2AFV, HSPA5 and NDUFV1. Gene ontology analyses of DEGs and DEPs revealed significant overlap with enrichment of genes/proteins related to metabolic process, biosynthetic process, cellular component organization, oxidative phosphorylation, alterations in glycolysis and ATP synthesis, Alzheimer's disease, chemokine-mediated inflammation and cytokine signalling pathways. CONCLUSION: The concomitant use of transcriptome and proteome expression to evaluate global changes in DCM has led to the identification of sixteen commonly altered entities as well as novel genes, proteins and pathways whose cardiac functions have yet to be deciphered. This data should contribute towards better management of the disease. PMID- 27711129 TI - Sex and Tissue Specificity of Peg3 Promoters. AB - The expression of mouse Peg3 (Paternally expressed gene 3) is driven by 4 promoters, including its main and three alternative promoters. The sexual, temporal and spatial specificity of these promoters was characterized in the current study. According to the results, the main promoter displays ubiquitous expression patterns throughout different stages and tissues. In contrast, the expression of Peg3 driven by the alternative promoter U2 was detected mainly in muscle and skin, but not in brain, starting from the late embryonic stage, revealing its tissue and stage specificity. The expression levels of both the main and U2 promoters are also sexually biased: the levels in females start higher but become lower than those in males during early postnatal stages. As an imprinted locus, the paternal alleles of these promoters are active whereas the maternal alleles are silent. Interestingly, deletion of the repressed maternal allele of the main promoter has an unusual effect on the opposite paternal allele, causing the up-regulation of both the main and U2 promoters. Overall, the promoters of Peg3 derive sexually biased and tissue-specific expression patterns. PMID- 27711128 TI - Effectiveness of Omega-3 Polyunsaturated Fatty Acids in Non-Alcoholic Fatty Liver Disease: A Meta-Analysis of Randomized Controlled Trials. AB - BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a clinical syndrome with the main characteristic of diffuse liver cells with fatty changes. The clinical evolution of NAFLD includes simple non-alcoholic fatty liver, non-alcoholic steatohepatitis (NASH), liver fibrosis and cirrhosis, and even hepatocellular carcinoma. METHODS AND FINDINGS: We conducted this review to identify the effectiveness of omega-3 polyunsaturated fatty acids (omega-3 PUFA) in NAFLD. We searched PubMed, Cochrane Library and Embase. All randomized controlled trials (RCTs) of omega-3 PUFA treatment for NAFLD were considered. Two reviewers assessed the quality of each study and collected data independently. Disagreements were resolved by discussion among the reviewers and any of the other authors of the paper. We performed a meta-analysis and reported summary estimates of outcomes as inverse variance (IV), fixed or random, with 95% confidence intervals (CIs). We included seven RCTs involving 442 patients (227 for the experimental group and 215 for the control group). All the patients were divided into two groups: one treated with omega-3 PUFA and the other was the control group (generally placebo). The demographics of the omega-3 PUFA and control groups were comparable. Beneficial changes in alanine aminotransferase (ALT) (IV 95% CI: -7.61 [-12.83 to -2.39], p = 0.004), total cholesterol (TC) (IV 95% CI: -13.41 [-21.44 to -5.38], p = 0.001), triglyceride (TG) (IV 95% CI: 43.96 [-51.21 to -36.71], p<0.00001) and high-density lipoprotein cholesterol (HDL-C) (IV 95% CI: 6.97 [2.05 to 11.90], p = 0.006) favored omega-3 PUFA treatment. Omega-3 PUFA tended towards a beneficial effect on aspartate aminotransferase (AST) (IV 95% CI: -6.89 [-17.71 to 3.92], p = 0.21), gamma glutamyl transferase (GGT) (IV 95% CI: -8.28 [-18.38 to 1.83], p = 0.11) and low density lipoprotein cholesterol (LDL-C) (IV 95% CI: -7.13 [-14.26 to 0.0], p = 0.05). CONCLUSIONS: Supplementation with omega-3 PUFA is a practical and effective treatment for NAFLD to decrease ALT, TC and increase HDL-C, especially to decrease TG. Omega-3 PUFA also has a tendency toward a beneficial effect on AST, GGT and LDL-C. More high-quality, large RCTs are needed to validate our findings. PMID- 27711130 TI - Highly Diverse Efficacy of Salvage Treatment Regimens for Relapsed or Refractory Peripheral T-Cell Lymphoma: A Systematic Review. AB - BACKGROUND: The goal of this study was to perform a systematic review to examine the efficacy and safety of various salvage therapy regimens on patients with relapsed/refractory PTCL. METHOD: The electronic searches were performed using PubMed, Cochrane Library, EMBASE, and Web of Science from inception through June 2015, with search terms related to relapsed/refractory PTCL, salvage chemotherapy regimens, and clinical trials. An eligible study met the following inclusion criteria: (1) Patients had refractory or relapsed PTCL; (2) drug regimens were used for salvage therapy; (3) the study was a clinical trial; (4) the study reported on a series of at least 10 patients of PTCL. RESULTS: Of 35 records identified, a total of 14 studies were eligible for systematic reviews, and 12 different salvage regimens were investigated. A total of 618 relapsed/refractory PTCL patients were identified. The ORRs ranged from 22% for those treated with lenalidomide to 86% for those with brentuximab vedotin. By the three most frequent subtypes, the ORRs ranged from 14.2% to 71.5% for patients with the PTCL NOS subtype, 8% to 54% for AITL subtypes, and 24% to 86% for the ALCL subtype. The medians of DOR, PFS, and OS ranged from 2.5 to 16.6 months, 2.6 to 13.3 months, and 3.6 to 14.5 months, respectively. The most frequently reported grade 3 or 4 adverse events (AEs) were hematological AEs, such as neutropenia and thrombocytopenia. CONCLUSION: The efficacy of salvage therapy regimens is highly diverse for patients with relapsed/refractory PTCL; this heterogeneity in therapeutic effects might be due to the diversity in mechanisms, PTCL subtype distribution, and/or numbers/profiles of prior therapy. Comparative studies with matched pair analysis are warranted for more evidence of the salvage treatment effect on relapsed or heavily pretreated patients with PTCL. PMID- 27711131 TI - Identification of Yeast Mutants Exhibiting Altered Sensitivity to Valinomycin and Nigericin Demonstrate Pleiotropic Effects of Ionophores on Cellular Processes. AB - Ionophores such as valinomycin and nigericin are potent tools for studying the impact of ion perturbance on cellular functions. To obtain a broader picture about molecular components involved in mediating the effects of these drugs on yeast cells under respiratory growth conditions, we performed a screening of the haploid deletion mutant library covering the Saccharomyces cerevisiae nonessential genes. We identified nearly 130 genes whose absence leads either to resistance or to hypersensitivity to valinomycin and/or nigericin. The processes affected by their protein products range from mitochondrial functions through ribosome biogenesis and telomere maintenance to vacuolar biogenesis and stress response. Comparison of the results with independent screenings performed by our and other laboratories demonstrates that although mitochondria might represent the main target for both ionophores, cellular response to the drugs is very complex and involves an intricate network of proteins connecting mitochondria, vacuoles, and other membrane compartments. PMID- 27711132 TI - DNA Methylation Patterns in Rat Mammary Carcinomas Induced by Pre- and Post Pubertal Irradiation. AB - Several lines of evidence indicate one's age at exposure to radiation strongly modifies the risk of radiation-induced breast cancer. We previously reported that rat mammary carcinomas induced by pre- and post-pubertal irradiation have distinct gene expression patterns, but the changes underlying these differences have not yet been characterized. The aim of this investigation was to see if differences in CpG DNA methylation were responsible for the differences in gene expression between age at exposure groups observed in our previous study. DNA was obtained from the mammary carcinomas arising in female Sprague-Dawley rats that were either untreated or irradiated (gamma-rays, 2 Gy) during the pre- or post pubertal period (3 or 7 weeks old). The DNA methylation was analyzed using CpG island microarrays and the results compared to the gene expression data from the original study. Global DNA hypomethylation in tumors was accompanied by gene specific hypermethylation, and occasionally, by unique tumor-specific patterns. We identified methylation-regulated gene expression candidates that distinguished the pre- and post-pubertal irradiation tumors, but these represented only 2 percent of the differentially expressed genes, suggesting that methylation is not a major or primary mechanism underlying the phenotypes. Functional analysis revealed that the candidate methylation-regulated genes were enriched for stem cell differentiation roles, which may be important in mammary cancer development and worth further investigation. However, the heterogeneity of human breast cancer means that the interpretation of molecular and phenotypic differences should be cautious, and take into account the co-variates such as hormone receptor status and cell-of-origin that may influence the associations. PMID- 27711133 TI - Developing a Deep Brain Stimulation Neuromodulation Network for Parkinson Disease, Essential Tremor, and Dystonia: Report of a Quality Improvement Project. AB - OBJECTIVE: To develop a process to improve patient outcomes from deep brain stimulation (DBS) surgery for Parkinson disease (PD), essential tremor (ET), and dystonia. METHODS: We employed standard quality improvement methodology using the Plan-Do-Study-Act process to improve patient selection, surgical DBS lead implantation, postoperative programming, and ongoing assessment of patient outcomes. RESULTS: The result of this quality improvement process was the development of a neuromodulation network. The key aspect of this program is rigorous patient assessment of both motor and non-motor outcomes tracked longitudinally using a REDCap database. We describe how this information is used to identify problems and to initiate Plan-Do-Study-Act cycles to address them. Preliminary outcomes data is presented for the cohort of PD and ET patients who have received surgery since the creation of the neuromodulation network. CONCLUSIONS: Careful outcomes tracking is essential to ensure quality in a complex therapeutic endeavor like DBS surgery for movement disorders. The REDCap database system is well suited to store outcomes data for the purpose of ongoing quality assurance monitoring. PMID- 27711134 TI - Interaction of Host Nucleolin with Influenza A Virus Nucleoprotein in the Early Phase of Infection Limits the Late Viral Gene Expression. AB - Influenza A virus nucleoprotein, is a multifunctional RNA-binding protein, encoded by segment-5 of the negative sense RNA genome. It serves as a key connector between the virus and the host during virus replication. It continuously shuttles between the cytoplasm and the nucleus interacting with various host cellular factors. In the current study, host proteins interacting with nucleoprotein of Influenza A virus of H1N1 2009 pandemic strain were identified by co-immunoprecipitation studies followed by MALDI-TOF/MS analysis. Here we report the host nucleolin, a major RNA-binding protein of the nucleolus as a novel interacting partner to influenza A virus nucleoprotein. We thus, explored the implications of this interaction in virus life cycle and our studies have shown that these two proteins interact early during infection in the cytoplasm of infected cells. Depletion of nucleolin in A549 cells by siRNA targeting endogenous nucleolin followed by influenza A virus infection, disrupted its interaction with viral nucleoprotein, resulting in increased expression of gene transcripts encoding late viral proteins; matrix (M1) and hemagglutinin (HA) in infected cells. On the contrary, over expression of nucleolin in cells transiently transfected with pEGFP-NCL construct followed by virus infection significantly reduced the late viral gene transcripts, and consequently the viral titer. Altered expression of late viral genes and titers following manipulation of host cellular nucleolin, proposes the functional importance of its interaction with nucleoprotein during influenza A virus infection. PMID- 27711135 TI - The Effect of Prophylactic Lamivudine plus Adefovir Therapy Compared with Lamivudine Alone in Preventing Hepatitis B Reactivation in Lymphoma Patients with High Baseline HBV DNA during Chemotherapy. AB - Prophylactic antiviral therapy is essential for lymphoma patients with high baseline HBV DNA who undergo cytotoxic chemotherapy. However, there are limited data on the optimal options. The present study was designed to compare the efficacy of prophylactic lamivudine (LAM) with lamivudine plus adefovir dipivoxil (LAM+ADV) in preventing hepatitis B virus (HBV) reactivation in lymphoma with, pre-chemotherapy HBV DNA load >=2000 IU/ml. We retrospectively analyzed the medical records of 86 lymphoma patients with baseline HBV DNA load >=2000 IU/ml during chemotherapy and received LAM or LAM+ADV as prophylaxis between January 1, 2008 and November 30, 2014 at Sun Yat-sen University Cancer Center, China. Sixty five patients received LAM and 21 received LAM+ADV. The rate was significantly lower in the LAM+ADV group compared with the LAM group for HBV reactivation (23.8% vs 55.4%; p = 0.012), while no difference was observed between the two groups in patients for HBV-related hepatitis (21.3% vs 33.3%; p = 0.349), and chemotherapy disruption (10.9% vs 19.0%; p = 0.337). In a multivariate analysis of factors associated with HBV reactivation in these patients, LAM+ADV treatment and HBeAg negative were the independent protective factors. Therefore, LAM+ADV should be considered for antiviral prophylaxis in lymphoma patients with pre chemotherapy HBV DNA load >=2000 IU/ml. Further study is warranted to confirm these findings. PMID- 27711137 TI - Comparison Study between Conventional Sequence and Slice-Encoding Metal Artifact Correction (SEMAC) in the Diagnosis of Postoperative Complications in Patients Receiving Lumbar Inter-Body Fusion and Pedicle Screw Fixation Surgery. AB - BACKGROUND AND PURPOSE: Slice-Encoding Metal Artifact Correction (SEMAC) sequence is one of the metal artifact reduction techniques of anatomical structure, but there has been no report about evaluation of post-operative complications. The purpose of this article is to compare the anatomical visibility between fast spin echo (FSE) and FSE-SEMAC and to evaluate the additional value of FSE-SEMAC in diagnostic confidence of the complications. MATERIALS AND METHODS: We conducted a retrospective study with 54 patients who received lumbar spinal surgery and MR images including FSE-SEMAC. For the semi-quantitative evaluation, the visibility of anatomical structures (neural foramen, bone-inter-body cage interface, central canal, nerve root in epidural space, back muscle, and bone-pedicle screw interface) was evaluated. For qualitative evaluation, we evaluated FSE and FSE with FSE-SEMAC independently, and recorded the diagnostic confidence level of post-operative complications. Generalized estimating equation regression analysis was used for statistical analysis, and a weighted kappa was used for inter observer agreement. RESULTS: Scores of 6 imaging findings with FSE-SEMAC were significantly higher than that of FSE (P-value < .0001). Inter-observer agreements show good reliability (weighted kappa = 0.45-0.75). Both reviewers deemed 37 (reviewer 1) or 19 more (reviewer 2) post-operative complications with FSE plus FSE-SEMAC, compared to FSE only. Except for central canal stenosis (P value = .2408), diagnostic confidence level for other post-operative complications were significantly higher with FSE plus FSE-SEMAC (P-value = .0000) than FSE. CONCLUSIONS: FSE-SEMAC significantly reduces image distortion, compared to FSE sequence in 3.0-T MR. Also, diagnostic confidence for post-operative complications was higher when FSE with additional FSE-SEMAC compared to FSE only. PMID- 27711136 TI - Peripersonal Space and Margin of Safety around the Body: Learning Visuo-Tactile Associations in a Humanoid Robot with Artificial Skin. AB - This paper investigates a biologically motivated model of peripersonal space through its implementation on a humanoid robot. Guided by the present understanding of the neurophysiology of the fronto-parietal system, we developed a computational model inspired by the receptive fields of polymodal neurons identified, for example, in brain areas F4 and VIP. The experiments on the iCub humanoid robot show that the peripersonal space representation i) can be learned efficiently and in real-time via a simple interaction with the robot, ii) can lead to the generation of behaviors like avoidance and reaching, and iii) can contribute to the understanding the biological principle of motor equivalence. More specifically, with respect to i) the present model contributes to hypothesizing a learning mechanisms for peripersonal space. In relation to point ii) we show how a relatively simple controller can exploit the learned receptive fields to generate either avoidance or reaching of an incoming stimulus and for iii) we show how the robot can select arbitrary body parts as the controlled end point of an avoidance or reaching movement. PMID- 27711138 TI - A Potential Magnetic Resonance Imaging Technique Based on Chemical Exchange Saturation Transfer for In Vivo gamma-Aminobutyric Acid Imaging. AB - PURPOSE: We developed a novel magnetic resonance imaging (MRI) technique based on chemical exchange saturation transfer (CEST) for GABA imaging and investigated the concentration-dependent CEST effect ofGABA in a rat model of brain tumor with blood-brain barrier (BBB) disruption. MATERIALS AND METHODS: All MRI studies were performed using a 7.0-T Agilent MRI scanner. Z-spectra for GABA were acquired at 7.0 T, 37 degrees C, and a pH of 7.0 using varying B1 amplitudes. CEST images of phantoms with different concentrations of GABA solutions (pH, 7.0) and other metabolites (glutamine, myoinositol, creatinine, and choline) were collected to investigate the concentration-dependent CEST effect of GABA and the potential contribution from other brain metabolites. CEST maps for GABA in rat brains with tumors were collected at baseline and 50 min, 1.5 h, and 2.0 h after the injection of GABA solution. RESULTS: The CEST effect of GABA was observed at approximately 2.75 parts per million(ppm) downfield from bulk water, and this effect increased with an increase in the B1 amplitude and remained steady after the B1 amplitude reached 6.0 MUT (255 Hz). The CEST effect of GABA was proportional to the GABA concentration in vitro. CEST imaging of GABA in a rat brain with a tumor and compromised BBB showed a gradual increase in the CEST effect after GABA injection. CONCLUSION: The findings of this study demonstrate the feasibility and potential of CEST MRI with the optimal B1 amplitude, which exhibits excellent spatial and temporal resolutions, to map changes in GABA. PMID- 27711139 TI - Dichoptic Metacontrast Masking Functions to Infer Transmission Delay in Optic Neuritis. AB - Optic neuritis (ON) has detrimental effects on the transmission of neuronal signals generated at the earliest stages of visual information processing. The amount, as well as the speed of transmitted visual signals is impaired. Measurements of visual evoked potentials (VEP) are often implemented in clinical routine. However, the specificity of VEPs is limited because multiple cortical areas are involved in the generation of P1 potentials, including feedback signals from higher cortical areas. Here, we show that dichoptic metacontrast masking can be used to estimate the temporal delay caused by ON. A group of 15 patients with unilateral ON, nine of which had sufficient visual acuity and volunteered to participate, and a group of healthy control subjects (N = 8) were presented with flashes of gray disks to one eye and flashes of gray annuli to the corresponding retinal location of the other eye. By asking subjects to report the subjective visibility of the target (i.e. the disk) while varying the stimulus onset asynchrony (SOA) between disk and annulus, we obtained typical U-shaped masking functions. From these functions we inferred the critical SOAmax at which the mask (i.e. the annulus) optimally suppressed the visibility of the target. ON associated transmission delay was estimated by comparing the SOAmax between conditions in which the disk had been presented to the affected and the mask to the other eye, and vice versa. SOAmax differed on average by 28 ms, suggesting a reduction in transmission speed in the affected eye. Compared to previously reported methods assessing perceptual consequences of altered neuronal transmission speed the presented method is more accurate as it is not limited by the observers' ability to judge subtle variations in perceived synchrony. PMID- 27711140 TI - Do Resit Exams Promote Lower Investments of Study Time? Theory and Data from a Laboratory Study. AB - Although many educational institutions allow students to resit exams, a recently proposed mathematical model suggests that this could lead to a dramatic reduction in study-time investment, especially in rational students. In the current study, we present a modification of this model in which we included some well-justified assumptions about learning and performance on multiple-choice tests, and we tested its predictions in two experiments in which participants were asked to invest fictional study time for a fictional exam. Consistent with our model, the prospect of a resit exam was found to promote lower investments of study time for a first exam and this effect was stronger for participants scoring higher on the cognitive reflection test. We also found that the negative effect of resit exams on study-time investment was attenuated when access to the resit was made uncertain by making it probabilistic or dependent on obtaining a minimal, non passing grade for the first attempt. Taken together, these results suggest that offering students resit exams may compromise the achievement of learning goals, and they raise the more general implication that second chances promote risky behavior. PMID- 27711141 TI - Mycobacterium tuberculosis Rv2882c Protein Induces Activation of Macrophages through TLR4 and Exhibits Vaccine Potential. AB - Macrophages constitute the first line of defense against Mycobacterium tuberculosis and are critical in linking innate and adaptive immunity. Therefore, the identification and characterization of mycobacterial proteins that modulate macrophage function are essential for understanding tuberculosis pathogenesis. In this study, we identified the novel macrophage-activating protein, Rv2882c, from M. tuberculosis culture filtrate proteins. Recombinant Rv2882c protein activated macrophages to secrete pro-inflammatory cytokines and express co-stimulatory and major histocompatibility complex molecules via Toll-like receptor 4, myeloid differentiation primary response protein 88, and Toll/IL-1 receptor-domain containing adaptor inducing IFN-beta. Mitogen-activated protein kinases and NF kappaB signaling pathways were involved in Rv2882c-induced macrophage activation. Further, Rv2882c-treated macrophages induced expansion of the effector/memory T cell population and Th1 immune responses. In addition, boosting Bacillus Calmette Guerin vaccination with Rv2882c improved protective efficacy against M. tuberculosis in our model system. These results suggest that Rv2882c is an antigen that could be used for tuberculosis vaccine development. PMID- 27711142 TI - A Study of BMP-2-Loaded Bipotential Electrolytic Complex around a Biphasic Calcium Phosphate-Derived (BCP) Scaffold for Repair of Large Segmental Bone Defect. AB - A bipotential polyelectrolyte complex with biphasic calcium phosphate (BCP) powder dispersion provides an excellent option for protein adsorption and cell attachment and can facilitate enhanced bone regeneration. Application of the bipotential polyelectrolyte complex embedded in a spongy scaffold for faster healing of large segmental bone defects (LSBD) can be a promising endeavor in tissue engineering application. In the present study, a hollow scaffold suitable for segmental long bone replacement was fabricated by the sponge replica method applying the microwave sintering process. The fabricated scaffold was coated with calcium alginate at the shell surface, and genipin-crosslinked chitosan with biphasic calcium phosphate (BCP) dispersion was loaded at the central hollow core. The chitosan core was subsequently loaded with BMP-2. The electrolytic complex was characterized using SEM, porosity measurement, FTIR spectroscopy and BMP-2 release for 30 days. In vitro studies such as MTT, live/dead, cell proliferation and cell differentiation were performed. The scaffold was implanted into a 12 mm critical size defect of a rabbit radius. The efficacy of this complex is evaluated through an in vivo study, one and two month post implantation. BV/TV ratio for BMP-2 loaded sample was (42+/-1.76) higher compared with hollow BCP scaffold (32+/-0.225). PMID- 27711143 TI - Targeted Genome Editing via CRISPR in the Pathogen Cryptococcus neoformans. AB - Low rates of homologous integration have hindered molecular genetic studies in Cryptococcus neoformans over the past 20 years, and new tools that facilitate genome manipulation in this important pathogen are greatly needed. To this end, we have investigated the use of a Class 2 CRISPR system in C. neoformans (formerly C. neoformans var. grubii). We first expressed a derivative of the Streptococcus pyogenes Cas9 nuclease in C. neoformans, and showed that it has no effect on growth, production of virulence factors in vitro, or virulence in a murine inhalation model. In proof of principle experiments, we tested the CAS9 construct in combination with multiple self-cleaving guide RNAs targeting the well-characterized phosphoribosylaminoamidazole carboxylase-encoding ADE2 gene. Utilizing combinations of transient and stable expression of our constructs, we revealed that functionality of our CRISPR constructs in C. neoformans is dependent upon the CAS9 construct being stably integrated into the genome, whilst transient expression of the guide RNA is sufficient to enhance rates of homologous recombination in the CAS9 genetic background. Given that the presence of the CRISPR nuclease does not influence virulence in a murine inhalation model, we have successfully demonstrated that this system is compatible with studies of C. neoformans pathogenesis and represents a powerful tool that can be exploited by researchers in the field. PMID- 27711144 TI - Accelerated Training of Skilled Birth Attendants in a Marginalized Population on the Thai-Myanmar Border: A Multiple Methods Program Evaluation. AB - BACKGROUND: To evaluate a skilled birth attendant (SBA) training program in a neglected population on the Thai-Myanmar border, we used multiple methods to show that refugee and migrant health workers can be given effective training in their own environment to become SBAs and teachers of SBAs. The loss of SBAs through resettlement to third countries necessitated urgent training of available workers to meet local needs. METHODS AND FINDINGS: All results were obtained from student records of theory grades and clinical log books. Qualitative evaluation of both the SBA and teacher programs was obtained using semi-structured interviews with supervisors and teachers. We also reviewed perinatal indicators over an eight year period, starting prior to the first training program until after the graduation of the fourth cohort of SBAs. RESULTS: Four SBA training programs scheduled between 2009 and 2015 resulted in 79/88 (90%) of students successfully completing a training program of 250 theory hours and 625 supervised clinical hours. All 79 students were able to: achieve pass grades on theory examination (median 80%, range [70-89]); obtain the required clinical experience within twelve months; achieve clinical competence to provide safe care during childbirth. In 2010-2011, five experienced SBAs completed a train-the-trainer (TOT) program and went on to facilitate further training programs. Perinatal indicators within Shoklo Malaria Research Unit (SMRU), such as place of birth, maternal and newborn outcomes, showed no significant differences before and after introduction of training or following graduate deployment in the local maternity units. Confidence, competence and teamwork emerged from qualitative evaluation by senior SBAs working with and supervising students in the clinics. CONCLUSIONS: We demonstrate that in resource-limited settings or in marginalized populations, it is possible to accelerate training of skilled birth attendants to provide safe maternity care. Education needs to be tailored to local needs to ensure evidence based care of women and their families. PMID- 27711145 TI - Interaction of Staphylococci with Human B cells. AB - Staphylococcus aureus is a leading cause of human infections worldwide. The pathogen produces numerous molecules that can interfere with recognition and binding by host innate immune cells, an initial step required for the ingestion and subsequent destruction of microbes by phagocytes. To better understand the interaction of this pathogen with human immune cells, we compared the association of S. aureus and S. epidermidis with leukocytes in human blood. We found that a significantly greater proportion of B cells associated with S. epidermidis relative to S. aureus. Complement components and complement receptors were important for the binding of B cells with S. epidermidis. Experiments using staphylococci inactivated by ultraviolet radiation and S. aureus isogenic deletion mutants indicated that S. aureus secretes molecules regulated by the SaeR/S two-component system that interfere with the ability of human B cells to bind this bacterium. We hypothesize that the relative inability of B cells to bind S. aureus contributes to the microbe's success as a human pathogen.

AB - Adaptations of vestibulo-ocular and optokinetic response eye movements have been studied as an experimental model of cerebellum-dependent motor learning. Several previous physiological and pharmacological studies have consistently suggested that the cerebellar flocculus (FL) Purkinje cells (P-cells) and the medial vestibular nucleus (MVN) neurons targeted by FL (FL-targeted MVN neurons) may respectively maintain the memory traces of short- and long-term adaptation. To study the basic structures of the FL-MVN synapses by light microscopy (LM) and electron microscopy (EM), we injected green florescence protein (GFP)-expressing lentivirus into FL to anterogradely label the FL P-cell axons in C57BL/6J mice. The FL P-cell axonal boutons were distributed in the magnocellular MVN and in the border region of parvocellular MVN and prepositus hypoglossi (PrH). In the magnocellular MVN, the FL-P cell axons mainly terminated on somata and proximal dendrites. On the other hand, in the parvocellular MVN/PrH, the FL P-cell axonal synaptic boutons mainly terminated on the relatively small-diameter (< 1 MUm) distal dendrites of MVN neurons, forming symmetrical synapses. The majority of such parvocellular MVN/PrH neurons were determined to be glutamatergic by immunocytochemistry and in-situ hybridization of GFP expressing transgenic mice. To further examine the spatial relationship between the synapses of FL P-cells and those of vestibular nerve on the neurons of the parvocellular MVN/PrH, we added injections of biotinylated dextran amine into the semicircular canal and anterogradely labeled vestibular nerve axons in some mice. The MVN dendrites receiving the FL P-cell axonal synaptic boutons often closely apposed vestibular nerve synaptic boutons in both LM and EM studies. Such a partial overlap of synaptic boutons of FL P-cell axons with those of vestibular nerve axons in the distal dendrites of MVN neurons suggests that inhibitory synapses of FL P-cells may influence the function of neighboring excitatory synapses of vestibular nerve in the parvocellular MVN/PrH neurons. PMID- 27711147 TI - Practice Effects on Story Memory and List Learning Tests in the Neuropsychological Assessment of Older Adults. AB - Two of the most commonly used methods to assess memory functioning in studies of cognitive aging and dementia are story memory and list learning tests. We hypothesized that the most commonly used story memory test, Wechsler's Logical Memory, would generate more pronounced practice effects than a well validated but less common list learning test, the Neuropsychological Assessment Battery (NAB) List Learning test. Two hundred eighty-seven older adults, ages 51 to 100 at baseline, completed both tests as part of a larger neuropsychological test battery on an annual basis. Up to five years of recall scores from participants who were diagnosed as cognitively normal (n = 96) or with mild cognitive impairment (MCI; n = 72) or Alzheimer's disease (AD; n = 121) at their most recent visit were analyzed with linear mixed effects regression to examine the interaction between the type of test and the number of times exposed to the test. Other variables, including age at baseline, sex, education, race, time (years) since baseline, and clinical diagnosis were also entered as fixed effects predictor variables. The results indicated that both tests produced significant practice effects in controls and MCI participants; in contrast, participants with AD declined or remained stable. However, for the delayed-but not the immediate recall condition, Logical Memory generated more pronounced practice effects than NAB List Learning (b = 0.16, p < .01 for controls). These differential practice effects were moderated by clinical diagnosis, such that controls and MCI participants-but not participants with AD-improved more on Logical Memory delayed recall than on delayed NAB List Learning delayed recall over five annual assessments. Because the Logical Memory test is ubiquitous in cognitive aging and neurodegenerative disease research, its tendency to produce marked practice effects-especially on the delayed recall condition-suggests a threat to its validity as a measure of new learning, an essential construct for dementia diagnosis. PMID- 27711149 TI - Spatial Effects on the Multiplicity of Plasmodium falciparum Infections. AB - As malaria is being pushed back on many frontiers and global case numbers are declining, accurate measurement and prediction of transmission becomes increasingly difficult. Low transmission settings are characterised by high levels of spatial heterogeneity, which stands in stark contrast to the widely used assumption of spatially homogeneous transmission used in mathematical transmission models for malaria. In the present study an individual-based mathematical malaria transmission model that incorporates multiple parasite clones, variable human exposure and duration of infection, limited mosquito flight distance and most importantly geographically heterogeneous human and mosquito population densities was used to illustrate the differences between homogeneous and heterogeneous transmission assumptions when aiming to predict surrogate indicators of transmission intensity such as population parasite prevalence or multiplicity of infection (MOI). In traditionally highly malaria endemic regions where most of the population harbours malaria parasites, humans are often infected with multiple parasite clones. However, studies have shown also in areas with low overall parasite prevalence, infection with multiple parasite clones is a common occurrence. Mathematical models assuming homogeneous transmission between humans and mosquitoes cannot explain these observations. Heterogeneity of transmission can arise from many factors including acquired immunity, body size and occupational exposure. In this study, we show that spatial heterogeneity has a profound effect on predictions of MOI and parasite prevalence. We illustrate, that models assuming homogeneous transmission underestimate average MOI in low transmission settings when compared to field data and that spatially heterogeneous models predict stable transmission at much lower overall parasite prevalence. Therefore it is very important that models used to guide malaria surveillance and control strategies in low transmission and elimination settings take into account the spatial features of the specific target area, including human and mosquito vector distribution. PMID- 27711150 TI - The Association of Current Violence from Adult Family Members with Adolescent Bullying Involvement and Suicidal Feelings. AB - Although several studies have reported that child physical abuse increased the risk for bullying involvement, the effect of current violence from adult family members (CVA) on bullying involvement and suicidal feelings among adolescents has not been sufficiently examined. This study investigated the association of CVA with adolescent bullying involvement and the interaction effect of CVA and bullying involvement on suicidal feelings. This cross-sectional study used data from a school-based survey with a general population of adolescents (grades 7 to 12). Data were collected using a self-report questionnaire completed by 17,530 students. Logistic regression analyses were performed to explore the association of CVA with adolescent bullying involvement and suicidal feelings. The overall response rate was 90.2%. The odds of students being characterized as bullies, victims, and bully-victims were higher among adolescents with CVA than without CVA (odds ratios (OR) = 2.9, 95% confidence interval (CI), [2.3-3.7], 4.6 [3.6 5.8], and 5.8 [4.4-7.6], respectively). Both CVA (OR = 3.4 [95% CI 2.7-4.3]) and bullying (bullies, victims, and bully-victims; OR = 2.0 [95% CI 1.6-2.6], 4.0 [3.1-5.1], 4.1 [3.0-5.6], respectively), were associated with increased odds of current suicidal feelings after adjusting for confounding factors. Furthermore, positive additive effects of CVA and all three types of bullying involvement on suicidal feelings were found. For example, bully-victims with CVA had about 19 fold higher odds of suicidal feelings compared with uninvolved adolescents without CVA. This study, although correlational, suggested that CVA avoidance might prevent bullying involvement and suicidal feelings in adolescents. PMID- 27711148 TI - Altered Modulation of Silent Period in Tongue Motor Cortex of Persistent Developmental Stuttering in Relation to Stuttering Severity. AB - Motor balance in developmental stuttering (DS) was investigated with Transcranial Magnetic Stimulation (TMS), with the aim to define novel neural markers of persistent DS in adulthood. Eleven DS adult males were evaluated with TMS on tongue primary motor cortex, compared to 15 matched fluent speakers, in a "state" condition (i.e. stutterers vs. fluent speakers, no overt stuttering). Motor and silent period thresholds (SPT), recruitment curves, and silent period durations were acquired by recording tongue motor evoked potentials. Tongue silent period duration was increased in DS, especially in the left hemisphere (P<0.05; Hedge's g or Cohen's dunbiased = 1.054, i.e. large effect size), suggesting a "state" condition of higher intracortical inhibition in left motor cortex networks. Differences in motor thresholds (different excitatory/inhibitory ratios in DS) were evident, as well as significant differences in SPT. In fluent speakers, the left hemisphere may be marginally more excitable than the right one in motor thresholds at lower muscular activation, while active motor thresholds and SPT were higher in the left hemisphere of DS with respect to the right one, resulting also in a positive correlation with stuttering severity. Pre-TMS electromyography data gave overlapping evidence. Findings suggest the existence of a complex intracortical balance in DS tongue primary motor cortex, with a particular interplay between excitatory and inhibitory mechanisms, also in neural substrates related to silent periods. Findings are discussed with respect to functional and structural impairments in stuttering, and are also proposed as novel neural markers of a stuttering "state" in persistent DS, helping to define more focused treatments (e.g. neuro-modulation). PMID- 27711152 TI - Throat Swabs and Sputum Culture as Predictors of P. aeruginosa or S. aureus Lung Colonization in Adult Cystic Fibrosis Patients. AB - BACKGROUND: Due to frequent infections in cystic fibrosis (CF) patients, repeated respiratory cultures are obtained to inform treatment. When patients are unable to expectorate sputum, clinicians obtain throat swabs as a surrogate for lower respiratory cultures. There is no clear data in adult subjects demonstrating the adequacy of throat swabs as a surrogate for sputum or BAL. Our study was designed to determine the utility of throat swabs in identifying lung colonization with common organisms in adults with CF. METHODS: Adult CF subjects (n = 20) underwent bronchoscopy with BAL. Prior to bronchoscopy, a throat swab was obtained. A sputum sample was obtained from subjects who were able to spontaneously expectorate. All samples were sent for standard microbiology culture. RESULTS: Using BAL as the gold standard, we found the positive predictive value for Pseudomonas aeruginosa to be 100% in both sputum and throat swab compared to BAL. However, the negative predictive value for P. aeruginosa was 60% and 50% in sputum and throat swab, respectively. Conversely, the positive predictive value for Staphylococcus aureus was 57% in sputum and only 41% in throat swab and the negative predictive value of S. aureus was 100% in sputum and throat swab compared to BAL. CONCLUSIONS: Our data show that positive sputum and throat culture findings of P. aeruginosa reflect results found on BAL fluid analysis, suggesting these are reasonable surrogates to determine lung colonization with P. aeruginosa. However, sputum and throat culture findings of S. aureus do not appear to reflect S. aureus colonization of the lung. PMID- 27711151 TI - Intraocular Pressure Induced Retinal Changes Identified Using Synchrotron Infrared Microscopy. AB - Infrared (IR) spectroscopy has been used to quantify chemical and structural characteristics of a wide range of materials including biological tissues. In this study, we examined spatial changes in the chemical characteristics of rat retina in response to intraocular pressure (IOP) elevation using synchrotron infrared microscopy (SIRM), a non-destructive imaging approach. IOP elevation was induced by placing a suture around the eye of anaesthetised rats. Retinal sections were collected onto transparent CaF2 slides 10 days following IOP elevation. Using combined SIRM spectra and chemical mapping approaches it was possible to quantify IOP induced changes in protein conformation and chemical distribution in various layers of the rat retina. We showed that 10 days following IOP elevation there was an increase in lipid and protein levels in the inner nuclear layer (INL) and ganglion cell layer (GCL). IOP elevation also resulted in an increase in nucleic acids in the INL. Analysis of SIRM spectra revealed a shift in amide peaks to lower vibrational frequencies with a more prominent second shoulder, which is consistent with the presence of cell death in specific layers of the retina. These changes were more substantial in the INL and GCL layers compared with those occurring in the outer nuclear layer. These outcomes demonstrate the utility of SIRM to quantify the effect of IOP elevation on specific layers of the retina. Thus SIRM may be a useful tool for the study of localised tissue changes in glaucoma and other eye diseases. PMID- 27711154 TI - Conversion to No-Till Improves Maize Nitrogen Use Efficiency in a Continuous Cover Cropping System. AB - A two-year experiment was conducted in the field to measure the combined impact of tilling and N fertilization on various agronomic traits related to nitrogen (N) use efficiency and to grain yield in maize cultivated in the presence of a cover crop. Four years after conversion to no-till, a significant increase in N use efficiency N harvest index, N remobilization and N remobilization efficiency was observed both under no and high N fertilization conditions. Moreover, we observed that grain yield and grain N content were higher under no-till conditions only when N fertilizers were applied. Thus, agronomic practices based on continuous no-till appear to be a promising for increasing N use efficiency in maize. PMID- 27711153 TI - Fumarate Production by Torulopsis glabrata: Engineering Heterologous Fumarase Expression and Improving Acid Tolerance. AB - Fumarate is a well-known biomass building block compound. However, the poor catalytic efficiency of fumarase is one of the major factors preventing its widespread production. To address this issue, we selected residues 159HPND162 of fumarase from Rhizopus oryzae as targets for site-directed mutagenesis based on molecular docking analysis. Twelve mutants were generated and characterized in detail. Kinetic studies showed that the Km values of the P160A, P160T, P160H, N161E, and D162W mutants were decreased, whereas Km values of H159Y, H159V, H159S, N161R, N161F, D162K, and D162M mutants were increased. In addition, all mutants displayed decreased catalytic efficiency except for the P160A mutant, whose kcat/Km was increased by 33.2%. Moreover, by overexpressing the P160A mutant, the engineered strain T.G-PMS-P160A was able to produce 5.2 g/L fumarate. To further enhance fumarate production, the acid tolerance of T.G-PMS-P160A was improved by deleting ade12, a component of the purine nucleotide cycle, and the resulting strain T.G(?ade12)-PMS-P160A produced 9.2 g/L fumarate. The strategy generated in this study opens up new avenues for pathway optimization and efficient production of natural products. PMID- 27711155 TI - Prevalence of Latent Tuberculosis among Health Care Workers in High Burden Countries: A Systematic Review and Meta-Analysis. AB - BACKGROUND: Tuberculosis is one of the leading causes of death worldwide. Twenty two high burden countries contributed to the majority of worldwide tuberculosis cases in 2015. Health care workers are at high risk of acquiring tuberculosis through occupational exposure. OBJECTIVE: To estimate the prevalence of latent tuberculosis infection (LTBI) among health care workers in high burden countries. METHODS: Databases including MEDLINE (Ovid), EMBASE (Ovid), CINAHL (Ovid) and ISI Web of Science (Thompson-Reuters), and grey literature were searched for English language records on relevant medical subject headings (MeSH) terms of LTBI and health care providers. Literature was systematically reviewed using EPPI Reviewer4 software. Prevalence and incidence of LTBI and 95% confidence intervals (CI) were reported. Pooled prevalence of LTBI and 95% CI were calculated using random-effects meta-analysis models and heterogeneity was assessed using I2 statistics. Sub-group analysis was conducted to assess the cause of heterogeneity. RESULTS: A total of 990 records were identified. Of those, 18 studies from only 7 high burden countries representing 10,078 subjects were included. Tuberculin skin test results were available for 9,545 participants. The pooled prevalence of LTBI was 47% (95% CI 34% to 60%, I2 = 99.6%). In subgroup analyses according to the country of the study, the pooled prevalence of LTBI was lowest in Brazil (37%) and highest in South Africa (64%). The pooled prevalence of LTBI among medical and nursing students was 26% (95% CI 6% to 46%, I2 = 99.3%) while the prevalence among all types of health care workers was 57% (95% CI 44% to 70%, I2 = 99.1%). Incidence of LTBI was available for health care workers in four countries. The cumulative incidence ranged from 2.8% in Brazilian medical students to 38% among all types of health care workers in South Africa. CONCLUSION: The findings of this study suggest that there is a high burden of LTBI among health care workers in high burden countries. Adequate infection control measures are warranted to prevent and control transmission in health care settings. PMID- 27711156 TI - In Vitro Antibacterial Activity of Rhodanine Derivatives against Pathogenic Clinical Isolates. AB - Bacterial infections present a serious challenge to healthcare practitioners due to the emergence of resistance to numerous conventional antibacterial drugs. Therefore, new bacterial targets and new antimicrobials are unmet medical needs. Rhodanine derivatives have been shown to possess potent antimicrobial activity via a novel mechanism. However, their potential use as antibacterials has not been fully examined. In this study, we determined the spectrum of activity of seven rhodanine derivatives (compounds Rh 1-7) against clinical isolates of Gram positive and Gram-negative bacterial strains and Candida albicans. We also synthesized and tested three additional compounds, ethyl ester and amide of rhodanine 2 (Rh 8 and Rh 10, respectively) and ethyl ester of rhodanine 3 (Rh 9) to determine the significance of the carboxyl group modification towards antibacterial activity and human serum albumin binding. A broth microdilution assay confirmed Rh 1-7 exhibit bactericidal activity against Gram-positive pathogens. Rh 2 had significant activity against various vancomycin-resistant (MIC90 = 4 MUM) and methicillin-resistant (MIC90 = 4 MUM) Staphylococcus aureus (VRSA and MRSA), Staphylococcus epidermidis (MIC = 4 MUM) and vancomycin resistant Enterococcus (VRE) strains (MIC90 = 8 MUM). The rhodanine compounds exhibited potent activity against Bacillus spp., including Bacillus anthracis, with MIC range of 2-8 MUM. In addition, they had potent activity against Clostridium difficile. The most potent compound, Rh 2, at 4 and 8 times its MIC, significantly decreased S. epidermidis biofilm mass by more than 35% and 45%, respectively. None of the rhodanine compounds showed antimicrobial activity (MIC > 128 MUM) against various 1) Gram-negative pathogens (Acinetobacter baumannii, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa, and Salmonella Typhimurium) or 2) strains of Candida albicans (MIC > 64 MUM). The MTS assay confirmed that rhodanines were not toxic to mouse murine macrophage (J774.1A) up to 64 MUM, human keratinocytes (HaCat) up to 32 MUM, and human ileocecal colorectal cell (HRT-18) up to 128 MUM. Overall, these data suggest that certain rhodanine compounds may have potential use for the treatment of several multidrug resistant Gram-positive bacterial infections. PMID- 27711157 TI - Multisite Phosphorylation of NuMA-Related LIN-5 Controls Mitotic Spindle Positioning in C. elegans. AB - During cell division, the mitotic spindle segregates replicated chromosomes to opposite poles of the cell, while the position of the spindle determines the plane of cleavage. Spindle positioning and chromosome segregation depend on pulling forces on microtubules extending from the centrosomes to the cell cortex. Critical in pulling force generation is the cortical anchoring of cytoplasmic dynein by a conserved ternary complex of Galpha, GPR-1/2, and LIN-5 proteins in C. elegans (Galpha-LGN-NuMA in mammals). Previously, we showed that the polarity kinase PKC-3 phosphorylates LIN-5 to control spindle positioning in early C. elegans embryos. Here, we investigate whether additional LIN-5 phosphorylations regulate cortical pulling forces, making use of targeted alteration of in vivo phosphorylated residues by CRISPR/Cas9-mediated genetic engineering. Four distinct in vivo phosphorylated LIN-5 residues were found to have critical functions in spindle positioning. Two of these residues form part of a 30 amino acid binding site for GPR-1, which we identified by reverse two-hybrid screening. We provide evidence for a dual-kinase mechanism, involving GSK3 phosphorylation of S659 followed by phosphorylation of S662 by casein kinase 1. These LIN-5 phosphorylations promote LIN-5-GPR-1/2 interaction and contribute to cortical pulling forces. The other two critical residues, T168 and T181, form part of a cyclin-dependent kinase consensus site and are phosphorylated by CDK1-cyclin B in vitro. We applied a novel strategy to characterize early embryonic defects in lethal T168,T181 knockin substitution mutants, and provide evidence for sequential LIN-5 N-terminal phosphorylation and dephosphorylation in dynein recruitment. Our data support that phosphorylation of multiple LIN-5 domains by different kinases contributes to a mechanism for spatiotemporal control of spindle positioning and chromosome segregation. PMID- 27711158 TI - Plasmodium vivax VIR Proteins Are Targets of Naturally-Acquired Antibody and T Cell Immune Responses to Malaria in Pregnant Women. AB - P. vivax infection during pregnancy has been associated with poor outcomes such as anemia, low birth weight and congenital malaria, thus representing an important global health problem. However, no vaccine is currently available for its prevention. Vir genes were the first putative virulent factors associated with P. vivax infections, yet very few studies have examined their potential role as targets of immunity. We investigated the immunogenic properties of five VIR proteins and two long synthetic peptides containing conserved VIR sequences (PvLP1 and PvLP2) in the context of the PregVax cohort study including women from five malaria endemic countries: Brazil, Colombia, Guatemala, India and Papua New Guinea (PNG) at different timepoints during and after pregnancy. Antibody responses against all antigens were detected in all populations, with PNG women presenting the highest levels overall. P. vivax infection at sample collection time was positively associated with antibody levels against PvLP1 (fold-increase: 1.60 at recruitment -first antenatal visit-) and PvLP2 (fold-increase: 1.63 at delivery), and P. falciparum co-infection was found to increase those responses (for PvLP1 at recruitment, fold-increase: 2.25). Levels of IgG against two VIR proteins at delivery were associated with higher birth weight (27 g increase per duplicating antibody levels, p<0.05). Peripheral blood mononuclear cells from PNG uninfected pregnant women had significantly higher antigen-specific IFN-gamma TH1 responses (p=0.006) and secreted less pro-inflammatory cytokines TNF and IL-6 after PvLP2 stimulation than P. vivax-infected women (p<0.05). These data demonstrate that VIR antigens induce the natural acquisition of antibody and T cell memory responses that might be important in immunity to P. vivax during pregnancy in very diverse geographical settings. PMID- 27711159 TI - Poor Linkage to Care Despite Significant Improvement in Access to Early cART in Central Poland - Data from Test and Keep in Care (TAK) Project. AB - BACKGROUND: The main objective of the TAK project is investigating barriers in accessing HIV care after HIV-diagnosis at the CBVCTs of central Poland. Here we describe factors associated with and changes over time in linkage to care and access to cART. METHOD: Data collected in 2010-2013 in CBVCTs were linked with HIV clinics records using unique identifiers. Individuals were followed from the day of CBVCTs visit until first clinical visit or 4/06/2014. Cox-proportional hazard models were used to identify factors associated with being linked to care and starting cART. RESULTS: In total 232 persons were diagnosed HIV-positive and 144 (62.1% 95%CI: 55.5-68.3) persons were linked to care. There was no change over time in linkage to care (p = 0.48), while time to starting cART decreased (p = 0.02). Multivariate factors associated with a lower rate of linkage to care were hetero/bisexual sexual orientation, lower education, not having an HIV positive partner and not using condoms in a stable relationship. Multivariate factors associated with starting cART were lower education, recent year of linked to care, and first HIV RNA and CD4 cell count. CONCLUSIONS: Benefits of linkage to care, measured by access to early treatment, steadily improved in recent years. However at least 1 in 3 persons aware of their HIV status in central Poland remained outside professional healthcare. Persons at higher risk of remaining outside care, thus target population for future interventions, are bi/heterosexuals and those with lower levels of education.

PMID- 27711160 TI - Sexual Dimorphism in Alcohol Induced Adipose Inflammation Relates to Liver Injury. AB - Alcoholic liver disease occurs due to chronic, heavy drinking and is driven both by metabolic alterations and immune cell activation. Women are at a higher risk than men for developing alcohol induced liver injury and this dimorphism is reflected in animal models of alcoholic liver disease. The importance of adipose tissue in alcoholic liver disease is emerging. Chronic alcohol consumption causes adipose tissue inflammation, which can influence liver injury. Sex differences in body fat composition are well known. However, it is still unclear if alcohol induced adipose tissue inflammation occurs in a sex-dependent manner. Here we have employed the clinically relevant NIAAA model of chronic-binge alcohol consumption to investigate this sexual dimorphism. We report that female mice have greater liver injury than male mice despite lower alcohol consumption. Chronic-binge alcohol induces adipose tissue inflammation in vivo in female mice, which is illustrated by increased expression of TNFalpha, IL-6, and CCL2, compared to only IL-6 induction in male adipose tissue. Further, macrophage activation markers such as CD68 as well as the pro-inflammatory activation markers CD11b and CD11c were higher in female adipose tissue. Interestingly, alcohol induced expression of TLR2, 3, 4, and 9 in female but not male adipose tissue, without affecting the TLR adaptor, MyD88. Higher trends of serum endotoxin in female mice may likely contribute to adipose tissue inflammation. In vitro chronic alcohol-mediated sensitization of macrophages to endotoxin is independent of sex. In summary, we demonstrate for the first time that there is a sexual dimorphism in alcohol-induced adipose tissue inflammation and female mice exhibit a higher degree of inflammation than male mice. PMID- 27711164 TI - Partner Disclosure and Early CD4 Response among HIV-Infected Adults Initiating Antiretroviral Treatment in Nairobi Kenya. AB - BACKGROUND: Disclosure of HIV serostatus can have significant benefits for people living with HIV/AIDS. However, there is limited data on whether partner disclosure influences ART treatment response. METHODS: We conducted a retrospective cohort study of newly diagnosed, ART-naive HIV-infected adults (>18 years) who enrolled at the Coptic Hope Center in Nairobi, Kenya between January 1st 2009 and July 1st 2011 and initiated ART within 3 months. Analysis was restricted to adults who reported to have either disclosed or not disclosed their HIV status to their partner. Analysis of CD4 response at 6 and 12 months post-ART was stratified by age group. RESULTS: Among 615 adults newly initiating ART with partner disclosure data and 12 month follow-up, mean age was 38 years and 52% were male; 76% reported that they had disclosed their HIV-status to their partner. Those who disclosed were significantly younger and more likely to be married/cohabitating than non-disclosers. At baseline, median CD4 counts were similar between disclosure groups. Among younger adults (< 38 years) those who disclosed had higher CD4 recovery than those who did not at 6 months post- ART (mean difference = 31, 95% CI 3 to 58 p = 0.03) but not at 12 months (mean difference = 17, 95% CI -19 to 52, p = 0.4). Among older adults (>= 38years) there was no observed difference in CD4 recovery at 6 or 12 months between disclosure groups. CONCLUSION: Among younger adults, disclosure of HIV status to partners may be associated with CD4 recovery following ART. PMID- 27711162 TI - A De Novo Genome Sequence Assembly of the Arabidopsis thaliana Accession Niederzenz-1 Displays Presence/Absence Variation and Strong Synteny. AB - Arabidopsis thaliana is the most important model organism for fundamental plant biology. The genome diversity of different accessions of this species has been intensively studied, for example in the 1001 genome project which led to the identification of many small nucleotide polymorphisms (SNPs) and small insertions and deletions (InDels). In addition, presence/absence variation (PAV), copy number variation (CNV) and mobile genetic elements contribute to genomic differences between A. thaliana accessions. To address larger genome rearrangements between the A. thaliana reference accession Columbia-0 (Col-0) and another accession of about average distance to Col-0, we created a de novo next generation sequencing (NGS)-based assembly from the accession Niederzenz-1 (Nd 1). The result was evaluated with respect to assembly strategy and synteny to Col 0. We provide a high quality genome sequence of the A. thaliana accession (Nd-1, LXSY01000000). The assembly displays an N50 of 0.590 Mbp and covers 99% of the Col-0 reference sequence. Scaffolds from the de novo assembly were positioned on the basis of sequence similarity to the reference. Errors in this automatic scaffold anchoring were manually corrected based on analyzing reciprocal best BLAST hits (RBHs) of genes. Comparison of the final Nd-1 assembly to the reference revealed duplications and deletions (PAV). We identified 826 insertions and 746 deletions in Nd-1. Randomly selected candidates of PAV were experimentally validated. Our Nd-1 de novo assembly allowed reliable identification of larger genic and intergenic variants, which was difficult or error-prone by short read mapping approaches alone. While overall sequence similarity as well as synteny is very high, we detected short and larger (affecting more than 100 bp) differences between Col-0 and Nd-1 based on bi directional comparisons. The de novo assembly provided here and additional assemblies that will certainly be published in the future will allow to describe the pan-genome of A. thaliana. PMID- 27711165 TI - Spatiotemporal Dynamics of Dexmedetomidine-Induced Electroencephalogram Oscillations. AB - An improved understanding of the neural correlates of altered arousal states is fundamental for precise brain state targeting in clinical settings. More specifically, electroencephalogram recordings are now increasingly being used to relate drug-specific oscillatory dynamics to clinically desired altered arousal states. Dexmedetomidine is an anesthetic adjunct typically administered in operating rooms and intensive care units to produce and maintain a sedative brain state. However, a high-density electroencephalogram characterization of the neural correlates of the dexmedetomidine-induced altered arousal state has not been previously accomplished. Therefore, we administered dexmedetomidine (1mcg/kg bolus over 10 minutes, followed by 0.7mcg/kg/hr over 50 minutes) and recorded high-density electroencephalogram signals in healthy volunteers, 18-36 years old (n = 8). We analyzed the data with multitaper spectral and global coherence methods. We found that dexmedetomidine was associated with increased slow-delta oscillations across the entire scalp, increased theta oscillations in occipital regions, increased spindle oscillations in frontal regions, and decreased beta oscillations across the entire scalp. The theta and spindle oscillations were globally coherent. During recovery from this state, these electroencephalogram signatures reverted towards baseline signatures. We report that dexmedetomidine induced electroencephalogram signatures more closely approximate the human sleep onset process than previously appreciated. We suggest that these signatures may be targeted by real time visualization of the electroencephalogram or spectrogram in clinical settings. Additionally, these signatures may aid the development of control systems for principled neurophysiological based brain-state targeting.

AB - Evolutionary divergence of the mitochondrial genome has given rise to distinct haplogroups. These haplogroups have arisen in specific geographical locations and are responsible for subtle functional changes in the mitochondria that may provide an evolutionary advantage in a given environment. Based on these functional differences, haplogroups could define disease susceptibility in chronic settings. In this study, we undertook a detailed neuropsychological analysis of a cohort of long-term HIV-1-infected individuals in conjunction with sequencing of their mitochondrial genomes. Stepwise regression analysis showed that the best model for predicting both working memory and declarative memory were age and years since diagnosis. In contrast, years since diagnosis and sub haplogroup were significantly predictive of psychomotor speed. Consistent with this, patients with haplogroup L3e obtained better scores on psychomotor speed and dexterity tasks when compared to the remainder of the cohort, suggesting that this haplogroup provides a protective advantage when faced with the combined stress of HIV-1 infection and long-term antiretroviral therapies. Differential performance on declarative memory tasks was noted for individuals with other sub L haplogroups, but these differences were not as robust as the association between L3e and psychomotor speed and dexterity tasks. This work provides evidence that mitochondrial haplogroup is related to neuropsychological test performance among patients in chronic disease settings such as HIV-1 infection.

AB - Herpes zoster (HZ) is associated with complications such as postherpetic neuralgia (PHN) and HZ ophthalmicus (HZO). However, few studies have focused on identifying patients having a high risk of PHN and HZO according to the initial presentation sites. The current study investigated these factors in a nationwide population-based cohort derived from Taiwan's Longitudinal Health Insurance Database. The results indicate that the initial presentation sites can predict the complication site of HZ. In this study, elderly patients were found to be more susceptible to HZ and were the first to present with neurological signs (HZN). Furthermore, compared with patients with HZO and other signs (HZT), those with HZN had a higher comorbidity risk. Patients with HZN showed a significantly higher visceral complication risk than did those with HZO (adjusted hazard ratio [HR] = 1.47, 95% confidence interval [CI] = 1.27-1.71). In addition, patients with HZT showed lower risks of ocular and neurological complications than did those with HZN after stratification by age and sex (adjusted HR = 0.46, 95% CI = 0.31-0.68 and HR = 0.73, 95% CI = 0.59-0.91, respectively). PMID- 27711169 TI - Chinese Version of the EQ-5D Preference Weights: Applicability in a Chinese General Population. AB - OBJECTIVES: This study aimed to test the reliability, validity and sensitivity of Chinese version of the EQ-5D preference weights in Chinese general people, examine the differences between the China value set and the UK, Japan and Korea value sets, and provide methods for evaluating and comparing the EQ-5D value sets of different countries. METHODS: A random sample of 2984 community residents (15 years or older) were interviewed using a questionnaire including the EQ-5D scale. Level of agreement, convergent validity, known-groups validity and sensitivity of the EQ-5D China, United Kingdom (UK), Japan and Korea value sets were determined. RESULTS: The mean EQ-5D index scores were significantly (P<0.05) different among the UK (0.964), Japan (0.981), Korea (0.987), and China (0.985) weights. High level of agreement (intraclass correlations coefficients > 0.75) and convergent validity (Pearson's correlation coefficients > 0.95) were found between each paired schemes. The EQ-5D index scores discriminated equally well for the four versions between levels of 10 known-groups (P< 0.05). The effect size and the relative efficiency statistics showed that the China weights had better sensitivity. CONCLUSIONS: The China EQ-5D preference weights show equivalent psychometric properties with those from the UK, Japan and Korea weights while slightly more sensitive to known group differences than those from the Japan and Korea weights. Considering both psychometric and sociocultural issues, the China scheme should be a priority as an EQ-5D based measure of the health related quality of life in Chinese general population. PMID- 27711172 TI - NT-proBNP Predicts Cardiovascular Death in the General Population Independent of Left Ventricular Mass and Function: Insights from a Large Population-Based Study with Long-Term Follow-Up. AB - AIMS: B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) predict cardiovascular endpoints in patients and all-cause death in the general population. This was assigned to their association with clinical cardiac remodelling defined as changes in size, shape and function of the heart. The aim of this study was to evaluate whether NT-proBNP and BNP were associated with cardiovascular and overall death independent of clinical cardiac remodelling measured by echocardiography as left ventricular hypertrophy (LVH), diastolic dysfunction and left ventricular ejection fraction (EF). METHODS AND RESULTS: In a general population-based cohort study from Germany (KORA-S3) with subjects' baseline age ranging from 25 to 74 years, cardiac morphology and function were assessed as left ventricular mass (LVM), diastolic dysfunction and EF by echocardiography and circulating NT-proBNP and BNP were measured at baseline. In 1,223 subjects with mortality follow-up information, we examined the association of baseline NT-proBNP and BNP with cardiovascular mortality (number of deaths = 52, median follow-up time = 12.9years) using Cox regression without and with adjustment for cardiovascular risk factors, LVM, diastolic dysfunction and EF. The risk of cardiovascular mortality increased with higher NT-proBNP levels measured at baseline (hazard ratio HR = 1.67 per unit increment in logNT-proBNP, p = 2.78*10-4, adjusted for age and sex). This increased risk persisted after adjustment for cardiovascular risk factors, LVM, diastolic dysfunction and EF (HR = 1.73; p = 0.047). When excluding subjects with relevant LVH (LVM to body surface area > 149g/m2 in men / 122g/m2 in women), the NT-proBNP association with mortality was still significant (n = 1,138; number of deaths = 35; HR = 1.48; p = 0.04). We found similar results for BNP. CONCLUSION: Our data confirms NT-proBNP and BNP as predictor of cardiovascular mortality in a large general population based study with long-term follow-up. Our study extends previously published population-based studies to younger and potentially healthier individuals without relevant LVH, diastolic dysfunction or LVD. PMID- 27711170 TI - Health Seeking Behaviour among Individuals with Presumptive Tuberculosis in Zambia. AB - BACKGROUND: Tuberculosis (TB) prevalence surveys offer a unique opportunity to study health seeking behaviour at the population level because they identify individuals with symptoms that should ideally prompt a health consultation. OBJECTIVE: To assess the health-seeking behaviour among individuals who were presumptive TB cases in a national population based TB prevalence survey. METHODS: A cross sectional survey was conducted between 2013 and 2014 among 66 survey clusters in Zambia. Clusters were census supervisory areas (CSAs). Participants (presumptive TB cases) were individuals aged 15 years and above; having either cough, fever or chest pain for 2 weeks or more; and/or having an abnormal or inconclusive chest x-ray image. All survey participants were interviewed about symptoms and had a chest X-ray taken. An in-depth interview was conducted to collect information on health seeking behaviour and previous TB treatment. RESULTS: Of the 6,708 participants, the majority reported at least a history of chest pain (3,426; 51.1%) followed by cough (2,405; 35.9%), and fever (1,030; 15.4%) for two weeks or more. Only 34.9% (2,340) had sought care for their symptoms, mainly (92%) at government health facilities. Of those who sought care, 13.9% (326) and 12.1% (283) had chest x-ray and sputum examinations, respectively. Those ever treated for TB were 9.6% (644); while 1.7% (114) was currently on treatment. The average time (in weeks) from onset of symptoms to first care-seeking was 3 for the presumptive TB cases. Males, urban dwellers and individuals in the highest wealth quintile were less likely to seek care for their symptoms. The likelihood of having ever been treated for TB was highest among males, urban dwellers; respondents aged 35-64 years, individuals in the highest wealth quintile, or HIV positive. CONCLUSION: Some presumptive TB patients delay care-seeking for their symptoms. The health system misses opportunities to diagnose TB among those who seek care. Improving health-seeking behaviour among males, urban dwellers and those with a higher social economic status; and addressing health care lapses in TB case detection is required if TB is to be effectively controlled in Zambia. PMID- 27711171 TI - Identification of Reference Genes for Quantitative Real Time PCR Assays in Aortic Tissue of Syrian Hamsters with Bicuspid Aortic Valve. AB - Bicuspid aortic valve (BAV) is the most frequent congenital cardiac malformation in humans, and appears frequently associated with dilatation of the ascending aorta. This association is likely the result of a common aetiology. Currently, a Syrian hamster strain with a relatively high (~40%) incidence of BAV constitutes the only spontaneous animal model of BAV disease. The characterization of molecular alterations in the aorta of hamsters with BAV may serve to identify pathophysiological mechanisms and molecular markers of disease in humans. In this report, we evaluate the expression of ten candidate reference genes in aortic tissue of hamsters in order to identify housekeeping genes for normalization using quantitative real time PCR (RT-qPCR) assays. A total of 51 adult (180-240 days old) and 56 old (300-440 days old) animals were used. They belonged to a control strain of hamsters with normal, tricuspid aortic valve (TAV; n = 30), or to the affected strain of hamsters with TAV (n = 45) or BAV (n = 32). The expression stability of the candidate reference genes was determined by RT-qPCR using three statistical algorithms, GeNorm, NormFinder and Bestkeeper. The expression analyses showed that the most stable reference genes for the three algorithms employed were Cdkn1beta, G3pdh and Polr2a. We propose the use of Cdkn1beta, or both Cdkn1beta and G3pdh as reference genes for mRNA expression analyses in Syrian hamster aorta. PMID- 27711173 TI - Understanding Healthcare Workers Self-Reported Practices, Knowledge and Attitude about Hand Hygiene in a Medical Setting in Rural India. AB - AIM: To describe self-reported practices and assess knowledge and attitudes regarding hand hygiene among healthcare workers in a rural Indian teaching hospital. SETTING: A rural teaching hospital and its associated medical and nursing colleges in the district of Ujjain, India. METHOD: The study population consisted of physicians, nurses, teaching staff, clinical instructors and nursing students. Self-administered questionnaires based on the World Health Organization Guidelines on Hand Hygiene in Healthcare were used. RESULTS: Out of 489 healthcare workers, 259 participated in the study (response rate = 53%). The proportion of healthcare workers that reported to 'always' practice hand hygiene in the selected situations varied from 40-96% amongst categories. Reported barriers to maintaining good hand hygiene were mainly related to high workload, scarcity of resources, lack of scientific information and the perception that priority is not given to hand hygiene, either on an individual or institutional level. Previous training on the topic had a statistically significant association with self-reported practice (p = 0.001). Ninety three per cent of the respondents were willing to attend training on hand hygiene in the near future. CONCLUSION: Self-reported knowledge and adherence varied between situations, but hand hygiene practices have the potential to improve if the identified constraints could be reduced. Future training should focus on enhancing healthcare workers' knowledge and understanding regarding the importance of persistent practice in all situations. PMID- 27711174 TI - Runaway Competition: A Correction and Extension of Results for a Model of Competitive Helping. AB - We investigate and generalize an existing model of competitive helping within a biological market, first introduced for a population of competing individuals in which one individual provides help to all others; the rest compete for the help available from this individual by providing help themselves. Our generalized model comprises two strategies in which each individual of a specific type provides the same amount of help as all other individuals of that type. Each individual's fitness function is dependent on this level of help, the cost of providing the help, and the fact that help is proportionally reciprocated by other individuals. Competitive helping occurs when individuals actively try to help more than other individuals. To assess the emergence of equilibrium help strategies as adopted by proportions of the population, we examine the competition over available help within two settings: replicator dynamics and agent-based numerical simulations. To move one step further in our generalization, we use the agent-based model to study the N-person competitive helping game, where all individuals in the population are heterogeneous with respect to help provided. Our results show that helping does not increase indefinitely with the population size, as concluded previously, and while there are some instances of an increase in help provided as a result of competition, this competition can be detrimental to all individuals and in most cases, one type simply gives up (thus evolving to a "no help" strategy). The degree to which an individual's help is reciprocated by the others in the population has strong implications in the long-term behaviour of equilibrium help levels of types of individuals (and of individuals themselves); these equilibrium help levels diverge from existing conjectures in current literature. Lastly, small amounts of passively provided (costless) help results in runaway competition among all individuals. PMID- 27711175 TI - Genetic Variation in the TAS2R38 Bitter Taste Receptor and Smoking Behaviors. AB - Common TAS2R38 taste receptor gene variants specify the ability to taste phenylthiocarbamide (PTC), 6-n-propylthiouracil (PROP) and structurally related compounds. Tobacco smoke contains a complex mixture of chemical substances of varying structure and functionality, some of which activate different taste receptors. Accordingly, it has been suggested that non-taster individuals may be more likely to smoke because of their inability to taste bitter compounds present in tobacco smoke, but results to date have been conflicting. We studied three cohorts: 237 European-Americans from the state of Georgia, 1,353 European Americans and 2,363 African-Americans from the Dallas Heart Study (DHS), and 4,973 African-Americans from the Dallas Biobank. Tobacco use data was collected and TAS2R38 polymorphisms were genotyped for all participants, and PTC taste sensitivity was assessed in the Georgia population. In the Georgia group, PTC tasters were less common among those who smoke: 71.5% of smokers were PTC tasters while 82.5% of non-smokers were PTC tasters (P = 0.03). The frequency of the TAS2R38 PAV taster haplotype showed a trend toward being lower in smokers (38.4%) than in non-smokers (43.1%), although this was not statistically significant (P = 0.31). In the DHS European-Americans, the taster haplotype was less common in smokers (37.0% vs. 44.0% in non-smokers, P = 0.003), and conversely the frequency of the non-taster haplotype was more common in smokers (58.7% vs. 51.5% in non smokers, P = 0.002). No difference in the frequency of these haplotypes was observed in African Americans in either the Dallas Heart Study or the Dallas Biobank. We conclude that TAS2R38 haplotypes are associated with smoking status in European-Americans but not in African-American populations. PTC taster status may play a role in protecting individuals from cigarette smoking in specific populations. PMID- 27711176 TI - Complete Protection against Influenza Virus H1N1 Strain A/PR/8/34 Challenge in Mice Immunized with Non-Adjuvanted Novirhabdovirus Vaccines. AB - Novirhabdoviruses like Viral Hemorrhagic Septicemia Virus (VHSV) and Infectious Hematopoietic Necrosis Virus (IHNV) are fish-infecting Rhabdoviruses belonging to the Mononegavirales order. By reverse genetics, we previously showed that a recombinant VHSV expressing the West Nile Virus (WNV) E glycoprotein could serve as a vaccine platform against WNV. In the current study, we aimed to evaluate the potential of the Novirhabdovirus platform as a vaccine against influenza virus. Recombinant Novirhabdoviruses, rVHSV-HA and rIHNV-HA, expressing at the viral surface the hemagglutinin HA ectodomain were generated and used to immunized mice. We showed that mice immunized with either, rVHSV-HA or rIHNV-HA, elicited a strong neutralizing antibody response against influenza virus. A complete protection was conferred to the immunized mice when challenged with a lethal dose of influenza H1N1 A/PR/8/34 virus. Furthermore we showed that although acting as inert antigen in mice, since naturally inactivated over 20 degrees C, mice immunized with rVHSV-HA or rIHNV-HA in the absence of adjuvant were also completely protected from a lethal challenge. Novirhabdoviruses platform are of particular interest as vaccines for mammals since they are cost effective to produce, relatively easy to generate and very effective to protect immunized animals. PMID- 27711178 TI - Tobacco Smoke Exposure and Eustachian Tube Disorders in US Children and Adolescents. AB - OBJECTIVES: To describe the association between active, environmental tobacco smoke (ETS) exposure and the prevalence of eustachian tube dysfunction (ETD) in the U.S. pediatric population. STUDY DESIGN: Cross-sectional. SETTING: U.S. representative demographic and audiometric data from the National Health and Nutrition Examination Survey (NHANES);2005-2010. SUBJECTS AND METHODS: The study consisted of 2,977 children aged 12-19 years. ETD was defined as middle ear pressure <100mm H20. ETS was defined as non-active smoking in individuals with serum cotinine over the limit of detection (>=0.015 ng/mL) and <10 ng/mL(N = 1559). RESULTS: The prevalence of ETD was 6.1%. After multivariate adjustment for age, sex, body mass index, education level, ethnicity, or having a cold, sinus problem or earache during the last 24 hours, compared to unexposed children, the odds ratios (95% confidence interval) of ETD for those exposed to ETS ages 12-15 in the first, second and third tertile of cotinine concentrations were, respectively, 1.38 (0.53-3.60), 0.99 (0.53-3.60) and 2.67 (1.12-6.34). Similarly, the odds ratios (95% confidence interval) of ETD for those exposed to ETS ages 16 19 in the first, second and third tertile of cotinine concentrations were, respectively, 1.28 (0.48-3.41), 0.99 (0.40-2.48) and 2.86 (1.19-6.88). CONCLUSION: These data suggest that children and adolescents exposed to high concentrations of ETS may have an increased prevalence of ETD. PMID- 27711177 TI - Structural Basis of the Heterodimer Formation between Cell Shape-Determining Proteins Csd1 and Csd2 from Helicobacter pylori. AB - Colonization of the human gastric mucosa by Helicobacter pylori requires its high motility, which depends on the helical cell shape. In H. pylori, several genes (csd1, csd2, csd3/hdpA, ccmA, csd4, csd5, and csd6) play key roles in determining the cell shape by alteration of cross-linking or by trimming of peptidoglycan stem peptides. H. pylori Csd1, Csd2, and Csd3/HdpA are M23B metallopeptidase family members and may act as d,d-endopeptidases to cleave the d-Ala4-mDAP3 peptide bond of cross-linked dimer muropeptides. Csd3 functions also as the d,d carboxypeptidase to cleave the d-Ala4-d-Ala5 bond of the muramyl pentapeptide. To provide a basis for understanding molecular functions of Csd1 and Csd2, we have carried out their structural characterizations. We have discovered that (i) Csd2 exists in monomer-dimer equilibrium and (ii) Csd1 and Csd2 form a heterodimer. We have determined crystal structures of the Csd2121-308 homodimer and the heterodimer between Csd1125-312 and Csd2121-308. Overall structures of Csd1125 312 and Csd2121-308 monomers are similar to each other, consisting of a helical domain and a LytM domain. The helical domains of both Csd1 and Csd2 play a key role in the formation of homodimers or heterodimers. The Csd1 LytM domain contains a catalytic site with a Zn2+ ion, which is coordinated by three conserved ligands and two water molecules, whereas the Csd2 LytM domain has incomplete metal ligands and no metal ion is bound. Structural knowledge of these proteins sheds light on the events that regulate the cell wall in H. pylori. PMID- 27711179 TI - Prevalence, Risk Factors, and Complications of Diabetes in the Kilimanjaro Region: A Population-Based Study from Tanzania. AB - BACKGROUND: In sub-Saharan Africa, diabetes is a growing burden, yet little is known about its prevalence, risk factors, and complications. To address these gaps and help inform public health efforts aimed at prevention and treatment, we conducted a community-based study assessing diabetes epidemiology. METHODS AND FINDINGS: We conducted a stratified, cluster-designed, serial cross-sectional household study from 2014-2015 in the Kilimanjaro Region, Tanzania. We used a three-stage cluster probability sampling method to randomly select individuals. To estimate prevalence, we screened individuals for glucose impairment, including diabetes, using hemoglobin A1C. We also screened for hypertension and obesity, and to assess for potential complications, individuals with diabetes were assessed for retinopathy, neuropathy, and nephropathy. We enrolled 481 adults from 346 urban and rural households. The prevalence of glucose impairment was 21.7% (95% CI 15.2-29.8), which included diabetes (5.7%; 95% CI 3.37-9.47) and glucose impairment with increased risk for diabetes (16.0%; 95% CI 10.2-24.0). Overweight or obesity status had an independent prevalence risk ratio for glucose impairment (2.16; 95% CI 1.39-3.36). Diabetes awareness was low (35.6%), and few individuals with diabetes were receiving biomedical treatment (33.3%). Diabetes associated complications were common (50.2%; 95% CI 33.7-66.7), including renal (12.0%; 95% CI 4.7-27.3), ophthalmic (49.6%; 95% CI 28.6-70.7), and neurological (28.8%; 95% CI 8.0-65.1) abnormalities. CONCLUSIONS: In a northern region of Tanzania, diabetes is an under-recognized health condition, despite the fact that many people either have diabetes or are at increased risk for developing diabetes. Most individuals were undiagnosed or untreated, and the prevalence of diabetes-associated complications was high. Public health efforts in this region will need to focus on reducing modifiable risk factors, which appear to include obesity, as well as early detection that includes increasing awareness. These findings highlight a growing urgency of diabetes prevention in this region as well as the need for treatment, including management of complications. PMID- 27711180 TI - Magnaporthe oryzae Glycine-Rich Secretion Protein, Rbf1 Critically Participates in Pathogenicity through the Focal Formation of the Biotrophic Interfacial Complex. AB - Magnaporthe oryzae, the fungus causing rice blast disease, should contend with host innate immunity to develop invasive hyphae (IH) within living host cells. However, molecular strategies to establish the biotrophic interactions are largely unknown. Here, we report the biological function of a M. oryzae-specific gene, Required-for-Focal-BIC-Formation 1 (RBF1). RBF1 expression was induced in appressoria and IH only when the fungus was inoculated to living plant tissues. Long-term successive imaging of live cell fluorescence revealed that the expression of RBF1 was upregulated each time the fungus crossed a host cell wall. Like other symplastic effector proteins of the rice blast fungus, Rbf1 accumulated in the biotrophic interfacial complex (BIC) and was translocated into the rice cytoplasm. RBF1-knockout mutants (Deltarbf1) were severely deficient in their virulence to rice leaves, but were capable of proliferating in abscisic acid-treated or salicylic acid-deficient rice plants. In rice leaves, Deltarbf1 inoculation caused necrosis and induced defense-related gene expression, which led to a higher level of diterpenoid phytoalexin accumulation than the wild-type fungus did. Deltarbf1 showed unusual differentiation of IH and dispersal of the normally BIC-focused effectors around the short primary hypha and the first bulbous cell. In the Deltarbf1-invaded cells, symplastic effectors were still translocated into rice cells but with a lower efficiency. These data indicate that RBF1 is a virulence gene essential for the focal BIC formation, which is critical for the rice blast fungus to suppress host immune responses. PMID- 27711181 TI - Comparison of Drive Counts and Mark-Resight As Methods of Population Size Estimation of Highly Dense Sika Deer (Cervus nippon) Populations. AB - Assessing temporal changes in abundance indices is an important issue in the management of large herbivore populations. The drive counts method has been frequently used as a deer abundance index in mountainous regions. However, despite an inherent risk for observation errors in drive counts, which increase with deer density, evaluations of the utility of drive counts at a high deer density remain scarce. We compared the drive counts and mark-resight (MR) methods in the evaluation of a highly dense sika deer population (MR estimates ranged between 11 and 53 individuals/km2) on Nakanoshima Island, Hokkaido, Japan, between 1999 and 2006. This deer population experienced two large reductions in density; approximately 200 animals in total were taken from the population through a large-scale population removal and a separate winter mass mortality event. Although the drive counts tracked temporal changes in deer abundance on the island, they overestimated the counts for all years in comparison to the MR method. Increased overestimation in drive count estimates after the winter mass mortality event may be due to a double count derived from increased deer movement and recovery of body condition secondary to the mitigation of density-dependent food limitations. Drive counts are unreliable because they are affected by unfavorable factors such as bad weather, and they are cost-prohibitive to repeat, which precludes the calculation of confidence intervals. Therefore, the use of drive counts to infer the deer abundance needs to be reconsidered. PMID- 27711182 TI - Genome-Wide Identification and Characterization of MicroRNAs and Target Genes in Lonicera japonica. AB - MiRNAs function in post-transcriptional regulation of gene expression and play very important roles in plant development. Lonicera japonica is one of the important medicinal plants in China. However, few studies on the discovery of conserved and novel miRNAs from L. japonica were reported. In this study, we employed deep sequencing technology to identify miRNAs in leaf and flower tissues of L. japonica. A total of 22.97 million clean reads from flower and leaf tissues were obtained, which generated 146 conserved miRNAs distributed in 20 families and 110 novel miRNAs. Accordingly, 72 differentially expressed miRNAs (P<=0.001) between leaves and flowers and their potential target genes were identified and validated. The qRT-PCR validation showed that majority of the differentially expressed miRNAs showed significant tissue-specific expression in L. japonica. Furthermore, the miRNA-mRNA and mRNA-mRNA regulatory networks were constructed using Cytoscape software. Taken together, this study identified a large number of miRNAs and target genes in L. japonica, which not only provides the first global miRNA expression profiles, but also sheds light on functional genomics research on L. japonica in the future. PMID- 27711183 TI - XRN1 Is a Species-Specific Virus Restriction Factor in Yeasts. AB - In eukaryotes, the degradation of cellular mRNAs is accomplished by Xrn1 and the cytoplasmic exosome. Because viral RNAs often lack canonical caps or poly-A tails, they can also be vulnerable to degradation by these host exonucleases. Yeast lack sophisticated mechanisms of innate and adaptive immunity, but do use RNA degradation as an antiviral defense mechanism. One model is that the RNA of yeast viruses is subject to degradation simply as a side effect of the intrinsic exonuclease activity of proteins involved in RNA metabolism. Contrary to this model, we find a highly refined, species-specific relationship between Xrn1p and the "L-A" totiviruses of different Saccharomyces yeast species. We show that the gene XRN1 has evolved rapidly under positive natural selection in Saccharomyces yeast, resulting in high levels of Xrn1p protein sequence divergence from one yeast species to the next. We also show that these sequence differences translate to differential interactions with the L-A virus, where Xrn1p from S. cerevisiae is most efficient at controlling the L-A virus that chronically infects S. cerevisiae, and Xrn1p from S. kudriavzevii is most efficient at controlling the L A-like virus that we have discovered within S. kudriavzevii. All Xrn1p orthologs are equivalent in their interaction with another virus-like parasite, the Ty1 retrotransposon. Thus, the activity of Xrn1p against totiviruses is not simply an incidental consequence of the enzymatic activity of Xrn1p, but rather Xrn1p co evolves with totiviruses to maintain its potent antiviral activity and limit viral propagation in Saccharomyces yeasts. Consistent with this, we demonstrated that Xrn1p physically interacts with the Gag protein encoded by the L-A virus, suggesting a host-virus interaction that is more complicated than just Xrn1p mediated nucleolytic digestion of viral RNAs. PMID- 27711184 TI - A Plaque Disruption Index Identifies Patients with Non-STE-Type 1 Myocardial Infarction within 24 Hours of Troponin Positivity. AB - BACKGROUND: Markers of plaque destabilization and disruption may have a role in identifying non-STE- type 1 Myocardial Infarction in patients presenting with troponin elevation. We hypothesized that a plaque disruption index (PDI) derived from multiple biomarkers and measured within 24 hours from the first detectable troponin in patients with acute non-STE- type 1 MI (NSTEMI-A) will confirm the diagnosis and identify these patients with higher specificity when compared to individual markers and coronary angiography. METHODS: We examined 4 biomarkers of plaque destabilization and disruption: myeloperoxidase (MPO), high-sensitivity interleukin-6, myeloid-related protein 8/14 (MRP8/14) and pregnancy-associated plasma protein-A (PAPP-A) in 83 consecutive patients in 4 groups: stable non obstructive coronary artery disease (CAD), stable obstructive CAD, NSTEMI-A (enrolled within 24 hours of troponin positivity), and NSTEMI-L (Late presentation NSTEMI, enrolled beyond the 24 hour limit). The PDI was calculated and the patients' coronary angiograms were reviewed for evidence of plaque disruption. The diagnostic performance of the PDI and angiography were compared. RESULTS: Compared to other biomarkers, MPO had the highest specificity (83%) for NSTEMI-A diagnosis (P<0.05). The PDI computed from PAPP-A, MRP8/14 and MPO was higher in NSTEMI-A patients compared to the other three groups (p<0.001) and had the highest diagnostic specificity (87%) with 79% sensitivity and 86% accuracy, which were higher compared to those obtained with MPO, but did not reach statistical significance (P>0.05 for all comparisons). The PDI had higher specificity and accuracy for NSTEMI-A diagnosis compared to coronary angiography (P<0.05). CONCLUSIONS: A PDI measured within 24 hour of troponin positivity has potential to identify subjects with acute Non-ST-elevation type 1 MI. Additional evidence using other marker combinations and investigation in a sufficiently large non-selected cohort is warranted to establish the diagnostic accuracy of the PDI and its potential role in differentiating type 1 and type 2 MI in patients presenting with troponin elevation of uncertain etiology. PMID- 27711185 TI - Exit from Synchrony in Joint Improvised Motion. AB - Motion synchrony correlates with effective and well-rated human interaction. However, people do not remain locked in synchrony; Instead, they repeatedly enter and exit synchrony. In many important interactions, such as therapy, marriage and parent-infant communication, it is the ability to exit and then re-enter synchrony that is thought to build strong relationship. The phenomenon of entry into zero-phase synchrony is well-studied experimentally and in terms of mathematical modeling. In contrast, exit-from-synchrony is under-studied. Here, we focus on human motion coordination, and examine the exit-from-synchrony phenomenon using experimental data from the mirror game paradigm, in which people perform joint improvised motion, and from human tracking of computer-generated stimuli. We present a mathematical mechanism that captures aspects of exit-from synchrony in human motion. The mechanism adds a random motion component when the accumulated velocity error between the players is small. We introduce this mechanism to several models for human coordinated motion, including the widely studied HKB model, and the predictor-corrector model of Noy, Dekel and Alon. In all models, the new mechanism produces realistic simulated behavior when compared to experimental data from the mirror game and from tracking of computer generated stimuli, including repeated entry and exit from zero-phase synchrony that generates a complexity of motion similar to that of human players. We hope that these results can inform future research on exit-from-synchrony, to better understand the dynamics of coordinated action of people and to enhance human computer and human-robot interaction.

AB - Circulating tumour cells (CTCs) play a key role in the metastasis process, as they are responsible for micrometastasis and are a valuable tool for monitoring patients in real-time. Moreover, efforts to develop new strategies for CTCs isolation and characterisation, and the translation of CTCs into clinical practice needs to overcome the limitation associated with the sole use of Epithelial Cell Adhesion Molecule (EpCAM) expression to purify this tumour cell subpopulation. CTCs are rare events in the blood of patients and are believed to represent the epithelial population from a primary tumour of epithelial origin, thus EpCAM immunoisolation is considered an appropriate strategy. The controversy stems from the impact that the more aggressive mesenchymal tumour phenotypes might have on the whole CTC population. In this work, we first characterised a panel of cell lines representative of tumour heterogeneity, confirming the existence of tumour cell subpopulations with restricted epithelial features and supporting the limitations of EpCAM-based technologies. We next developed customised polystyrene magnetic beads coated with antibodies to efficiently isolate the phenotypically different subpopulations of CTCs from the peripheral blood mononuclear cells (PBMCs) of patients with metastatic cancer. Besides EpCAM, we propose Epidermal Growth Factor Receptor (EGFR) as an additional isolation marker for efficient CTCs detection.

AB - Glioblastoma multiforme (GBM) is the most common and aggressive primary intracranial brain tumor in adults with a mean survival of 14 to 15 months. Aberrant activation of the epidermal growth factor receptor (EGFR) plays a significant role in GBM progression, with amplification or overexpression of EGFR in 60% of GBM tumors. To target EGFR expressed by GBM, we have developed a strategy to deliver the coding sequence for cetuximab, an anti-EGFR antibody, directly to the CNS using an adeno-associated virus serotype rh.10 gene transfer vector. The data demonstrates that single, local delivery of an anti-EGFR antibody by an AAVrh.10 vector coding for cetuximab (AAVrh.10Cetmab) reduces GBM tumor growth and increases survival in xenograft mouse models of a human GBM EGFR expressing cell line and patient-derived GBM. AAVrh10.CetMab-treated mice displayed a reduction in cachexia, a significant decrease in tumor volume and a prolonged survival following therapy. Adeno-associated-directed delivery of a gene encoding a therapeutic anti-EGFR monoclonal antibody may be an effective strategy to treat GBM.

AB - Effective immunity against Bordetella pertussis is currently under discussion following the stacking evidence of pertussis resurgence in the vaccinated population. Natural immunity is more effective than vaccine-induced immunity indicating that knowledge on infection-induced responses may contribute to improve vaccination strategies. We applied a systems biology approach comprising microarray, flow cytometry and multiplex immunoassays to unravel the molecular and cellular signatures in unprotected mice and protected mice with infection induced immunity, around a B. pertussis challenge. Pre-existing systemic memory Th1/Th17 cells, memory B-cells, and mucosal IgA specific for Ptx, Vag8, Fim2/3 were detected in the protected mice 56 days after an experimental infection. In addition, pre-existing high activity and reactivation of pulmonary innate cells such as alveolar macrophages, M-cells and goblet cells was detected. The pro inflammatory responses in the lungs and serum, and neutrophil recruitment in the spleen upon an infectious challenge of unprotected mice were absent in protected mice. Instead, fast pulmonary immune responses in protected mice led to efficient bacterial clearance and harbored potential new gene markers that contribute to immunity against B. pertussis. These responses comprised of innate makers, such as Clca3, Retlna, Glycam1, Gp2, and Umod, next to adaptive markers, such as CCR6+ B-cells, CCR6+ Th17 cells and CXCR6+ T-cells as demonstrated by transcriptome analysis. In conclusion, besides effective Th1/Th17 and mucosal IgA responses, the primary infection-induced immunity benefits from activation of pulmonary resident innate immune cells, achieved by local pathogen-recognition. These molecular signatures of primary infection-induced immunity provided potential markers to improve vaccine-induced immunity against B. pertussis.

AB - Nasal airflow is greater in one nostril than in the other because of transient asymmetric nasal passage obstruction by erectile tissue. The extent of obstruction alternates across nostrils with periodicity referred to as the nasal cycle. The nasal cycle is related to autonomic arousal and is indicative of asymmetry in brain function. Moreover, alterations in nasal cycle periodicity have been linked to various diseases. There is therefore need for a tool allowing continuous accurate measurement and recording of airflow in each nostril separately. Here we provide detailed instructions for constructing such a tool at minimal cost and effort. We demonstrate application of the tool in 33 right handed healthy subjects, and derive several statistical measures for nasal cycle characterization. Using these measures applied to 24-hour recordings we observed that: 1: subjects spent slightly longer in left over right nostril dominance (left = 2.63 +/- 0.89 hours, right = 2.17 +/- 0.89 hours, t(32) = 2.07, p < 0.05), 2: cycle duration was shorter in wake than in sleep (wake = 2.02 +/- 1.7 hours, sleep = 4.5 +/- 1.7 hours, (t(30) = 5.73, p < 0.0001). 3: slower breathing was associated with a more powerful cycle (the extent of difference across nostrils) (r = 0.4, p < 0.0001), and 4: the cycle was influenced by body posture such that lying on one side was associated with greater flow in the contralateral nostril (p < 0.002). Finally, we provide evidence for an airflow cycle in each nostril alone. These results provide characterization of an easily obtained measure that may have diagnostic implications for neurological disease and cognitive state. PMID- 27711190 TI - The Role of Vitamin D in the Transcriptional Program of Human Pregnancy. AB - BACKGROUND: Patterns of gene expression of human pregnancy are poorly understood. In a trial of vitamin D supplementation in pregnant women, peripheral blood transcriptomes were measured longitudinally on 30 women and used to characterize gene co-expression networks. OBJECTIVE: Studies suggest that increased maternal Vitamin D levels may reduce the risk of asthma in early life, yet the underlying mechanisms have not been examined. In this study, we used a network-based approach to examine changes in gene expression profiles during the course of normal pregnancy and evaluated their association with maternal Vitamin D levels. DESIGN: The VDAART study is a randomized clinical trial of vitamin D supplementation in pregnancy for reduction of pediatric asthma risk. The trial enrolled 881 women at 10-18 weeks of gestation. Longitudinal gene expression measures were obtained on thirty pregnant women, using RNA isolated from peripheral blood samples obtained in the first and third trimesters. Differentially expressed genes were identified using significance of analysis of microarrays (SAM), and clustered using a weighted gene co-expression network analysis (WGCNA). Gene-set enrichment was performed to identify major biological pathways. RESULTS: Comparison of transcriptional profiles between first and third trimesters of pregnancy identified 5839 significantly differentially expressed genes (FDR<0.05). Weighted gene co-expression network analysis clustered these transcripts into 14 co-expression modules of which two showed significant correlation with maternal vitamin D levels. Pathway analysis of these two modules revealed genes enriched in immune defense pathways and extracellular matrix reorganization as well as genes enriched in notch signaling and transcription factor networks. CONCLUSION: Our data show that gene expression profiles of healthy pregnant women change during the course of pregnancy and suggest that maternal Vitamin D levels influence transcriptional profiles. These alterations of the maternal transcriptome may contribute to fetal immune imprinting and reduce allergic sensitization in early life. TRIAL REGISTRATION: clinicaltrials.gov NCT00920621. PMID- 27711192 TI - Structural Insights into the Methylation of C1402 in 16S rRNA by Methyltransferase RsmI. AB - RsmI and RsmH are conserved S-Adenosylmethionine (AdoMet)-dependent methyltransferases (MTases) that are responsible for the 2'-O-methylation and N4 methylation of C1402 in bacterial 16S rRNA, respectively. Methylation of m4Cm1402 plays a role in fine-tuning the shape and functions of the P-site to increase the decoding fidelity, and was recently found to contribute to the virulence of Staphylococcus aureus in host animals. Here we report the 2.20-A crystal structure of homodimeric RsmI from Escherichia coli in complex with the cofactor AdoMet. RsmI consists of an N-terminal putative RNA-binding domain (NTD) and a C terminal catalytic domain (CTD) with a Rossmann-like fold, and belongs to the class III MTase family. AdoMet is specifically bound into a negatively charged deep pocket formed by both domains by making extensive contacts. Structure-based mutagenesis and isothermal titration calorimetry (ITC) assays revealed Asp100 and Ala124 are vital for AdoMet-binding. Although the overall fold of RsmI shows remarkable similarities to the characterized MTases involved in vitamin B12 biosynthesis, it exhibits a distinct charge distribution especially around the AdoMet-binding pocket because of different substrate specificity. The docking model of RsmI-AdoMet-RNA ternary complex suggested a possible base-flipping mechanism of the substrate RNA that has been observed in several known RNA MTases. Our structural and biochemical studies provide novel insights into the catalytic mechanism of C1402 methylation in 16S rRNA. PMID- 27711191 TI - Vasodilator-Stimulated Phosphoprotein Activity Is Required for Coxiella burnetii Growth in Human Macrophages. AB - Coxiella burnetii is an intracellular bacterial pathogen that causes human Q fever, an acute flu-like illness that can progress to chronic endocarditis and liver and bone infections. Humans are typically infected by aerosol-mediated transmission, and C. burnetii initially targets alveolar macrophages wherein the pathogen replicates in a phagolysosome-like niche known as the parasitophorous vacuole (PV). C. burnetii manipulates host cAMP-dependent protein kinase (PKA) signaling to promote PV formation, cell survival, and bacterial replication. In this study, we identified the actin regulatory protein vasodilator-stimulated phosphoprotein (VASP) as a PKA substrate that is increasingly phosphorylated at S157 and S239 during C. burnetii infection. Avirulent and virulent C. burnetii triggered increased levels of phosphorylated VASP in macrophage-like THP-1 cells and primary human alveolar macrophages, and this event required the Calpha subunit of PKA. VASP phosphorylation also required bacterial protein synthesis and secretion of effector proteins via a type IV secretion system, indicating the pathogen actively triggers prolonged VASP phosphorylation. Optimal PV formation and intracellular bacterial replication required VASP activity, as siRNA-mediated depletion of VASP reduced PV size and bacterial growth. Interestingly, ectopic expression of a phospho-mimetic VASP (S239E) mutant protein prevented optimal PV formation, whereas VASP (S157E) mutant expression had no effect. VASP (S239E) expression also prevented trafficking of bead-containing phagosomes to the PV, indicating proper VASP activity is critical for heterotypic fusion events that control PV expansion in macrophages. Finally, expression of dominant negative VASP (S157A) in C. burnetii-infected cells impaired PV formation, confirming importance of the protein for proper infection. This study provides the first evidence of VASP manipulation by an intravacuolar bacterial pathogen via activation of PKA in human macrophages. PMID- 27711193 TI - Effective L-Tyrosine Hydroxylation by Native and Immobilized Tyrosinase. AB - Hydroxylation of L-tyrosine to 3,4-dihydroxyphenylalanine (L-DOPA) by immobilized tyrosinase in the presence of ascorbic acid (AH2), which reduces DOPA-quinone to L-DOPA, is characterized by low reaction yields that are mainly caused by the suicide inactivation of tyrosinase by L-DOPA and AH2. The main aim of this work was to compare processes with native and immobilized tyrosinase to identify the conditions that limit suicide inactivation and produce substrate conversions to L DOPA of above 50% using HPLC analysis. It was shown that immobilized tyrosinase does not suffer from partitioning and diffusion effects, allowing a direct comparison of the reactions performed with both forms of the enzyme. In typical processes, additional aeration was applied and boron ions to produce the L-DOPA and AH2 complex and hydroxylamine to close the cycle of enzyme active center transformations. It was shown that the commonly used pH 9 buffer increased enzyme stability, with concomitant reduced reactivity of 76%, and that under these conditions, the maximal substrate conversion was approximately 25 (native) to 30% (immobilized enzyme). To increase reaction yield, the pH of the reaction mixture was reduced to 8 and 7, producing L-DOPA yields of approximately 95% (native enzyme) and 70% (immobilized). A three-fold increase in the bound enzyme load achieved 95% conversion in two successive runs, but in the third one, tyrosinase lost its activity due to strong suicide inactivation caused by L-DOPA processing. In this case, the cost of the immobilized enzyme preparation is not overcome by its reuse over time, and native tyrosinase may be more economically feasible for a single use in L-DOPA production. The practical importance of the obtained results is that highly efficient hydroxylation of monophenols by tyrosinase can be obtained by selecting the proper reaction pH and is a compromise between complexation and enzyme reactivity.

PMID- 27711194 TI - Equine Chorionic Gonadotropin Modulates the Expression of Genes Related to the Structure and Function of the Bovine Corpus Luteum. AB - We hypothesized that stimulatory and superovulatory treatments, using equine chorionic gonadotropin (eCG), modulate the expression of genes related to insulin, cellular modelling and angiogenesis signaling pathways in the bovine corpus luteum (CL). Therefore, we investigated: 1-the effect of these treatments on circulating insulin and somatomedin C concentrations and on gene and protein expression of INSR, IGF1 and IGFR1, as well as other insulin signaling molecules; 2-the effects of eCG on gene and protein expression of INSR, IGF1, GLUT4 and NFKB1A in bovine luteal cells; and 3-the effect of stimulatory and superovulatory treatments on gene and protein expression of ANG, ANGPT1, NOS2, ADM, PRSS2, MMP9 and PLAU. Serum insulin did not differ among groups (P = 0.96). However, serum somatomedin C levels were higher in both stimulated and superovulated groups compared to the control (P = 0.01). In stimulated cows, lower expression of INSR mRNA and higher expression of NFKB1A mRNA and IGF1 protein were observed. In superovulated cows, lower INSR mRNA expression, but higher INSR protein expression and higher IGF1, IGFR1 and NFKB1A gene and protein expression were observed. Expression of angiogenesis and cellular modelling pathway-related factors were as follows: ANGPT1 and PLAU protein expression were higher and MMP9 gene and protein expression were lower in stimulated animals. In superovulated cows, ANGPT1 mRNA expression was higher and ANG mRNA expression was lower. PRSS2 gene and protein expression were lower in both stimulated and superovulated animals related to the control. In vitro, eCG stimulated luteal cells P4 production as well as INSR and GLUT4 protein expression. In summary, our results suggest that superovulatory treatment induced ovarian proliferative changes accompanied by increased expression of genes providing the CL more energy substrate, whereas stimulatory treatment increased lipogenic activity, angiogenesis and plasticity of the extracellular matrix (ECM). PMID- 27711196 TI - JAK3 as an Emerging Target for Topical Treatment of Inflammatory Skin Diseases. AB - The recent interest and elucidation of the JAK/STAT signaling pathway created new targets for the treatment of inflammatory skin diseases (ISDs). JAK inhibitors in oral and topical formulations have shown beneficial results in psoriasis and alopecia areata. Patients suffering from other ISDs might also benefit from JAK inhibition. Given the development of specific JAK inhibitors, the expression patterns of JAKs in different ISDs needs to be clarified. We aimed to analyze the expression of JAK/STAT family members in a set of prevalent ISDs: psoriasis, lichen planus (LP), cutaneous lupus erythematosus (CLE), atopic dermatitis (AD), pyoderma gangrenosum (PG) and alopecia areata (AA) versus healthy controls for (p)JAK1, (p)JAK2, (p)JAK3, (p)TYK2, pSTAT1, pSTAT2 and pSTAT3. The epidermis carried in all ISDs, except for CLE, a strong JAK3 signature. The dermal infiltrate showed a more diverse expression pattern. JAK1, JAK2 and JAK3 were significantly overexpressed in PG and AD suggesting the need for pan-JAK inhibitors. In contrast, psoriasis and LP showed only JAK1 and JAK3 upregulation, while AA and CLE were characterized by a single dermal JAK signal (pJAK3 and pJAK1, respectively). This indicates that the latter diseases may benefit from more targeted JAK inhibitors. Our in vitro keratinocyte psoriasis model displayed reversal of the psoriatic JAK profile following tofacitinib treatment. This direct interaction with keratinocytes may decrease the need for deep skin penetration of topical JAK inhibitors in order to exert its effects on dermal immune cells. In conclusion, these results point to the important contribution of the JAK/STAT pathway in several ISDs. Considering the epidermal JAK3 expression levels, great interest should go to the investigation of topical JAK3 inhibitors as therapeutic option of ISDs. PMID- 27711198 TI - Health Status of Sand Flathead (Platycephalus bassensis), Inhabiting an Industrialised and Urbanised Embayment, Port Phillip Bay, Victoria as Measured by Biomarkers of Exposure and Effects. AB - Port Phillip Bay, Australia, is a large semi-closed bay with over four million people living in its catchment basin. The Bay receives waters from the Yarra River which drains the city of Melbourne, as well as receiving the discharges of sewage treatment plants and petrochemical and agricultural chemicals. A 1999 study demonstrated that fish inhabiting Port Phillip Bay showed signs of effects related to pollutant exposure despite pollution management practices having been implemented for over a decade. To assess the current health status of the fish inhabiting the Bay, a follow up survey was conducted in 2015. A suite of biomarkers of exposure and effects were measured to determine the health status of Port Phillip Bay sand flathead (Platycephalus bassensis), namely ethoxyresorufin-O-deethylase (EROD) activity, polycyclic aromatic hydrocarbons (PAH) biliary metabolites, carboxylesterase activity (CbE) and DNA damage (8-oxo dG). The reduction in EROD activity in the present study suggests a decline in the presence of EROD activity-inducing chemicals within the Bay since the 1990s. Fish collected in the most industrialised/urbanised sites did not display higher PAH metabolite levels than those in less developed areas of the Bay. Ratios of PAH biliary metabolite types were used to indicate PAH contaminant origin. Ratios indicated fish collected at Corio Bay and Hobsons Bay were subjected to increased low molecular weight hydrocarbons of petrogenic origin, likely attributed to the close proximity of these sites to oil refineries, compared to PAH biliary metabolites in fish from Geelong Arm and Mordialloc. Quantification of DNA damage indicated a localised effect of exposure to pollutants, with a 10-fold higher DNA damage level in fish sampled from the industrial site of Corio Bay relative to the less developed site of Sorrento. Overall, integration of biomarkers by multivariate analysis indicated that the health of fish collected in industrialised areas was compromised, with biologically significant biomarkers of effects (LSI, CF and DNA damage) discriminating between individuals collected in industrialised areas from observations made in fish collected in less developed areas of the Bay. PMID- 27711197 TI - A Multistate Toggle Switch Defines Fungal Cell Fates and Is Regulated by Synergistic Genetic Cues. AB - Heritable epigenetic changes underlie the ability of cells to differentiate into distinct cell types. Here, we demonstrate that the fungal pathogen Candida tropicalis exhibits multipotency, undergoing stochastic and reversible switching between three cellular states. The three cell states exhibit unique cellular morphologies, growth rates, and global gene expression profiles. Genetic analysis identified six transcription factors that play key roles in regulating cell differentiation. In particular, we show that forced expression of Wor1 or Efg1 transcription factors can be used to manipulate transitions between all three cell states. A model for tristability is proposed in which Wor1 and Efg1 are self activating but mutually antagonistic transcription factors, thereby forming a symmetrical self-activating toggle switch. We explicitly test this model and show that ectopic expression of WOR1 can induce white-to-hybrid-to-opaque switching, whereas ectopic expression of EFG1 drives switching in the opposite direction, from opaque-to-hybrid-to-white cell states. We also address the stability of induced cell states and demonstrate that stable differentiation events require ectopic gene expression in combination with chromatin-based cues. These studies therefore experimentally test a model of multistate stability and demonstrate that transcriptional circuits act synergistically with chromatin-based changes to drive cell state transitions. We also establish close mechanistic parallels between phenotypic switching in unicellular fungi and cell fate decisions during stem cell reprogramming. PMID- 27711199 TI - A Randomized Controlled Trial Comparing the Effects of Sitagliptin and Glimepiride on Endothelial Function and Metabolic Parameters: Sapporo Athero Incretin Study 1 (SAIS1). AB - OBJECTIVES: The DPP-4 inhibitors are incretin-related drugs that improve hyperglycemia in a glucose-dependent manner and have been reported to exert favorable effects on atherosclerosis. However, it has not been fully elucidated whether DPP-4 inhibitors are able to improve endothelial function in patients with type 2 diabetes. Therefore, we investigated the efficacy of sitagliptin, a DPP-4 inhibitor, on endothelial function and glycemic metabolism compared with that of the sulfonylurea glimepiride. MATERIALS AND METHODS: In this multicenter, prospective, randomized parallel-group comparison study, 103 outpatients with type 2 diabetes (aged 59.9 +/- 9.9 years with HbA1c levels of 7.5 +/- 0.4%) with dietary cure only and/or current metformin treatment were enrolled and randomly assigned to receive sitagliptin or glimepiride therapy once daily for 26 weeks. Flow-mediated dilation (FMD), a comprehensive panel of hemodynamic parameters (Task Force(r) Monitor), and serum metabolic markers were assessed before and after the treatment. RESULTS: During the study period, no statistically significant change in %FMD was seen in both groups (sitagliptin, 5.6 to 5.6%; glimepiride, 5.6 to 6.0%). Secretory units of islets in transplantation, TNF alpha, adiponectin and biological antioxidant potential significantly improved in the sitagliptin group, and superoxide dismutase also tended to improve in the sitagliptin group, while improvements in HbA1c levels were similar between groups. Cardiac index, blood pressure and most other metabolic parameters were not different. CONCLUSIONS: Regardless of glycemic improvement, early sitagliptin therapy did not affect endothelial function but may provide favorable effects on beta-cell function and on inflammatory and oxidative stress in patients with type 2 diabetes without advanced atherosclerosis.

PMID- 27711200 TI - Cost-Effectiveness of Hepatitis C Treatment for People Who Inject Drugs and the Impact of the Type of Epidemic; Extrapolating from Amsterdam, the Netherlands. AB - BACKGROUND: People who inject drugs (PWID) are disproportionally affected by the hepatitis C virus (HCV) infection. The efficacy of HCV treatment has significantly improved in recent years with the introduction of direct-acting antivirals (DAAs). However, DAAs are more costly than pegylated-interferon and ribavirin (PegIFN/RBV). We aimed to assess the cost-effectiveness of four HCV treatment strategies among PWID and treatment scale-up. METHODS: An individual based model was used describing HIV and HCV transmission and disease progression among PWID. We considered two epidemiological situations. A declining epidemic, based on the situation in Amsterdam, the Netherlands, and a stable HCV epidemic, as observed in other settings. Data on HCV incidence, prevalence, treatment setting and uptake were derived from observed data among PWID in Amsterdam. We assessed the incremental cost-effectiveness ratio (ICER, costs in ?/quality adjusted life year (QALY)) of four treatment strategies: 1) PegIFN/RBV; 2) sofosbuvir/RBV for genotype 2-3 and dual DAA for genotype 1-4; 3) Dual DAA for all genotypes; 4) Dual DAA with 3x treatment uptake. RESULTS: In both types of epidemic, dual DAA therapy was most cost-effective strategy. In the declining epidemic, dual DAA yielded an ICER of 344 ?/QALY while in the stable epidemic dual DAA led to cost-savings. Scaling-up treatment was also highly cost effective. Our results were robust over a range of sensitivity analyses. CONCLUSION: HCV treatment with DAA-containing regimens is a highly cost-effective intervention among PWID. Based on the economic and population benefits of scaling up treatment, stronger efforts are needed to achieve higher uptake rates among PWID. PMID- 27711201 TI - Distinct Effects of p19 RNA Silencing Suppressor on Small RNA Mediated Pathways in Plants. AB - RNA silencing is one of the main defense mechanisms employed by plants to fight viruses. In change, viruses have evolved silencing suppressor proteins to neutralize antiviral silencing. Since the endogenous and antiviral functions of RNA silencing pathway rely on common components, it was suggested that viral suppressors interfere with endogenous silencing pathway contributing to viral symptom development. In this work, we aimed to understand the effects of the tombusviral p19 suppressor on endogenous and antiviral silencing during genuine virus infection. We showed that ectopically expressed p19 sequesters endogenous small RNAs (sRNAs) in the absence, but not in the presence of virus infection. Our presented data question the generalized model in which the sequestration of endogenous sRNAs by the viral suppressor contributes to the viral symptom development. We further showed that p19 preferentially binds the perfectly paired ds-viral small interfering RNAs (vsiRNAs) but does not select based on their sequence or the type of the 5' nucleotide. Finally, co-immunoprecipitation of sRNAs with AGO1 or AGO2 from virus-infected plants revealed that p19 specifically impairs vsiRNA loading into AGO1 but not AGO2. Our findings, coupled with the fact that p19-expressing wild type Cymbidium ringspot virus (CymRSV) overcomes the Nicotiana benthamiana silencing based defense killing the host, suggest that AGO1 is the main effector of antiviral silencing in this host-virus combination. PMID- 27711203 TI - Health-Related Quality of Life in Korean Adults with Hearing Impairment: The Korea National Health and Nutrition Examination Survey 2010 to 2012. AB - BACKGROUND: As the global population ages, disabling hearing impairment (HI) have been increased rapidly. The impact of HI on health-related quality of life (HRQoL) is of great importance to aid the development of strategic plans and to guide therapeutic interventions. PURPOSE: To evaluate HRQoL in Korean adults with different degrees of HI using EuroQol five-dimensional (EQ-5D) and EQ-visual analogue scale (VAS), the preference-based generic measures of HRQoL. METHODS: Using a representative dataset from the Korea National Health and Nutrition Examination Survey (KNHANES) from January 2010 to December 2012, EQ-5D questionnaire and EQ- VAS scores of subjects with HI were compared with those of subjects without HI. Logistic regression analysis, with adjustment for covariates, was used to evaluate the impact of HI on HRQoL scales. HI was defined according to the hearing thresholds of pure-tone averages at 0.5, 1, 2, and 3 kHz of the better hearing ear as follows; mild HI (26 to < 40 dB) and moderate to severe HI (>= 40 dB). RESULTS: Of the 16,449 Korean adults in KNHANES (age, 45.0 +/- 0.2 years; male, 49.7%), 1757 (weighted prevalence, 7.6%) had mild HI and 890 (3.6%) had moderate to severe HI. Subjects with HI had impaired HRQoL as compared with subjects without HI (EQ-5D, 0.96 +/- 0.00 vs. 0.88+/-0.00 vs. 0.86 +/- 0.01 for control vs. mild HI vs. moderate to severe HI, p < 0.001; EQ-VAS, 75.10 +/- 0.18 vs. 67.48 +/- 0.63 vs. 66.24 +/- 0.92 for control vs. mild HI vs. moderate to severe HI, p < 0.001). After adjusting for socio-demographic factors (age, gender, household income, education level, presence of spouse) and health-related behaviors (smoking status, alcohol intake, regular exercise), psychological stress, and the presence of comorbidities (diabetes, hypercholesterolemia, hypertension, decreased eGFR, and tinnitus), EQ-VAS remained impaired in the moderate to severe HI group (61.72+/-1.69) as compared with the control group (65.68 +/- 1.26, p = 0.004), but EQ-5D impairment disappeared (0.86 +/- 0.02 vs.0.88+/-0.01 for moderate to severe HI vs. control, p = 0.058). CONCLUSION: After adjusting for socio-demographic and psychosocial factors and comorbidities, Korean adults with moderate to severe HI rated their health statuses lower than subjects without HI. PMID- 27711202 TI - Sphingosine 1-Phosphate Activation of EGFR As a Novel Target for Meningitic Escherichia coli Penetration of the Blood-Brain Barrier. AB - Central nervous system (CNS) infection continues to be an important cause of mortality and morbidity, necessitating new approaches for investigating its pathogenesis, prevention and therapy. Escherichia coli is the most common Gram negative bacillary organism causing meningitis, which develops following penetration of the blood-brain barrier (BBB). By chemical library screening, we identified epidermal growth factor receptor (EGFR) as a contributor to E. coli invasion of the BBB in vitro. Here, we obtained the direct evidence that CNS infecting E. coli exploited sphingosine 1-phosphate (S1P) for EGFR activation in penetration of the BBB in vitro and in vivo. We found that S1P was upstream of EGFR and participated in EGFR activation through S1P receptor as well as through S1P-mediated up-regulation of EGFR-related ligand HB-EGF, and blockade of S1P function through targeting sphingosine kinase and S1P receptor inhibited EGFR activation, and also E. coli invasion of the BBB. We further found that both S1P and EGFR activations occurred in response to the same E. coli proteins (OmpA, FimH, NlpI), and that S1P and EGFR promoted E. coli invasion of the BBB by activating the downstream c-Src. These findings indicate that S1P and EGFR represent the novel host targets for meningitic E. coli penetration of the BBB, and counteracting such targets provide a novel approach for controlling E. coli meningitis in the era of increasing resistance to conventional antibiotics. PMID- 27711204 TI - Metabolic Response to NAD Depletion across Cell Lines Is Highly Variable. AB - Nicotinamide adenine dinucleotide (NAD) is a cofactor involved in a wide range of cellular metabolic processes and is a key metabolite required for tumor growth. NAMPT, nicotinamide phosphoribosyltransferase, which converts nicotinamide (NAM) to nicotinamide mononucleotide (NMN), the immediate precursor of NAD, is an attractive therapeutic target as inhibition of NAMPT reduces cellular NAD levels and inhibits tumor growth in vivo. However, there is limited understanding of the metabolic response to NAD depletion across cancer cell lines and whether all cell lines respond in a uniform manner. To explore this we selected two non-small cell lung carcinoma cell lines that are sensitive to the NAMPT inhibitor GNE-617 (A549, NCI-H1334), one that shows intermediate sensitivity (NCI-H441), and one that is insensitive (LC-KJ). Even though NAD was reduced in all cell lines there was surprising heterogeneity in their metabolic response. Both sensitive cell lines reduced glycolysis and levels of di- and tri-nucleotides and modestly increased oxidative phosphorylation, but they differed in their ability to combat oxidative stress. H1334 cells activated the stress kinase AMPK, whereas A549 cells were unable to activate AMPK as they contain a mutation in LKB1, which prevents activation of AMPK. However, A549 cells increased utilization of the Pentose Phosphate pathway (PPP) and had lower reactive oxygen species (ROS) levels than H1334 cells, indicating that A549 cells are better able to modulate an increase in oxidative stress. Inherent resistance of LC-KJ cells is associated with higher baseline levels of NADPH and a delayed reduction of NAD upon NAMPT inhibition. Our data reveals that cell lines show heterogeneous response to NAD depletion and that the underlying molecular and genetic framework in cells can influence the metabolic response to NAMPT inhibition. PMID- 27711205 TI - Zoonoses As Ecological Entities: A Case Review of Plague. AB - As a zoonosis, Plague is also an ecological entity, a complex system of ecological interactions between the pathogen, the hosts, and the spatiotemporal variations of its ecosystems. Five reservoir system models have been proposed: (i) assemblages of small mammals with different levels of susceptibility and roles in the maintenance and amplification of the cycle; (ii) species-specific chronic infection models; (ii) flea vectors as the true reservoirs; (iii) Telluric Plague, and (iv) a metapopulation arrangement for species with a discrete spatial organization, following a source-sink dynamic of extinction and recolonization with naive potential hosts. The diversity of the community that harbors the reservoir system affects the transmission cycle by predation, competition, and dilution effect. Plague has notable environmental constraints, depending on altitude (500+ meters), warm and dry climates, and conditions for high productivity events for expansion of the transmission cycle. Human impacts are altering Plague dynamics by altering landscape and the faunal composition of the foci and adjacent areas, usually increasing the presence and number of human cases and outbreaks. Climatic change is also affecting the range of its occurrence. In the current transitional state of zoonosis as a whole, Plague is at risk of becoming a public health problem in poor countries where ecosystem erosion, anthropic invasion of new areas, and climate change increase the contact of the population with reservoir systems, giving new urgency for ecologic research that further details its maintenance in the wild, the spillover events, and how it links to human cases. PMID- 27711206 TI - Emergence of Epidemic Dengue-1 Virus in the Southern Province of Sri Lanka. AB - BACKGROUND: Dengue is a frequent cause of acute febrile illness with an expanding global distribution. Since the 1960s, dengue in Sri Lanka has been documented primarily along the heavily urbanized western coast with periodic shifting of serotypes. Outbreaks from 2005-2008 were attributed to a new clade of DENV-3 and more recently to a newly introduced genotype of DENV-1. In 2007, we conducted etiologic surveillance of acute febrile illness in the Southern Province and confirmed dengue in only 6.3% of febrile patients, with no cases of DENV-1 identified. To re-evaluate the importance of dengue as an etiology of acute febrile illness in this region, we renewed fever surveillance in the Southern Province to newly identify and characterize dengue. METHODOLOGY/PRINCIPAL FINDINGS: A cross-sectional surveillance study was conducted at the largest tertiary care hospital in the Southern Province from 2012-2013. A total of 976 patients hospitalized with acute undifferentiated fever were enrolled, with 64.3% male and 31.4% children. Convalescent blood samples were collected from 877 (89.6%). Dengue virus isolation, dengue RT-PCR, and paired IgG ELISA were performed. Acute dengue was confirmed as the etiology for 388 (39.8%) of 976 hospitalizations, with most cases (291, 75.0%) confirmed virologically and by multiple methods. Among 351 cases of virologically confirmed dengue, 320 (91.2%) were due to DENV-1. Acute dengue was associated with self-reported rural residence, travel, and months having greatest rainfall. Sequencing of selected dengue viruses revealed that sequences were most closely related to those described from China and Southeast Asia, not nearby India. CONCLUSIONS/SIGNIFICANCE: We describe the first epidemic of DENV-1 in the Southern Province of Sri Lanka in a population known to be susceptible to this serotype because of prior study. Dengue accounted for 40% of acute febrile illnesses in the current study. The emergence of DENV-1 as the foremost serotype in this densely populated but agrarian population highlights the changing epidemiology of dengue and the need for continued surveillance and prevention. PMID- 27711208 TI - Modeled Impacts of Chronic Wasting Disease on White-Tailed Deer in a Semi-Arid Environment. AB - White-tailed deer are a culturally and economically important game species in North America, especially in South Texas. The recent discovery of chronic wasting disease (CWD) in captive deer facilities in Texas has increased concern about the potential emergence of CWD in free-ranging deer. The concern is exacerbated because much of the South Texas region is a semi-arid environment with variable rainfall, where precipitation is strongly correlated with fawn recruitment. Further, the marginally productive rangelands, in combination with erratic fawn recruitment, results in populations that are frequently density-independent, and thus sensitive to additive mortality. It is unknown how a deer population in semi arid regions would respond to the presence of CWD. We used long-term empirical datasets from a lightly harvested (2% annual harvest) population in conjunction with 3 prevalence growth rates from CWD afflicted areas (0.26%, 0.83%, and 2.3% increases per year) via a multi-stage partially deterministic model to simulate a deer population for 25 years under four scenarios: 1) without CWD and without harvest, 2) with CWD and without harvest, 3) with CWD and male harvest only, and 4) with CWD and harvest of both sexes. The modeled populations without CWD and without harvest averaged a 1.43% annual increase over 25 years; incorporation of 2% annual harvest of both sexes resulted in a stable population. The model with slowest CWD prevalence rate growth (0.26% annually) without harvest resulted in stable populations but the addition of 1% harvest resulted in population declines. Further, the male age structure in CWD models became skewed to younger age classes. We incorporated fawn:doe ratios from three CWD afflicted areas in Wisconsin and Wyoming into the model with 0.26% annual increase in prevalence and populations did not begin to decline until ~10%, ~16%, and ~26% of deer were harvested annually. Deer populations in variable environments rely on high adult survivorship to buffer the low and erratic fawn recruitment rates. The increase in additive mortality rates for adults via CWD negatively impacted simulated population trends to the extent that hunter opportunity would be greatly reduced. Our results improve understanding of the potential influences of CWD on deer populations in semi-arid environments with implications for deer managers, disease ecologists, and policy makers. PMID- 27711207 TI - Genetic Modifiers of White Blood Cell Count, Albuminuria and Glomerular Filtration Rate in Children with Sickle Cell Anemia. AB - Discovery and validation of genetic variants that influence disease severity in children with sickle cell anemia (SCA) could lead to early identification of high risk patients, better screening strategies, and intervention with targeted and preventive therapy. We hypothesized that newly identified genetic risk factors for the general African American population could also impact laboratory biomarkers known to contribute to the clinical disease expression of SCA, including variants influencing the white blood cell count and the development of albuminuria and abnormal glomerular filtration rate. We first investigated candidate genetic polymorphisms in well-characterized SCA pediatric cohorts from three prospective NHLBI-supported clinical trials: HUSTLE, SWiTCH, and TWiTCH. We also performed whole exome sequencing to identify novel genetic variants, using both a discovery and a validation cohort. Among candidate genes, DARC rs2814778 polymorphism regulating Duffy antigen expression had a clear influence with significantly increased WBC and neutrophil counts, but did not affect the maximum tolerated dose of hydroxyurea therapy. The APOL1 G1 polymorphism, an identified risk factor for non-diabetic renal disease, was associated with albuminuria. Whole exome sequencing discovered several novel variants that maintained significance in the validation cohorts, including ZFHX4 polymorphisms affecting both the leukocyte and neutrophil counts, as well as AGGF1, CYP4B1, CUBN, TOR2A, PKD1L2, and CD163 variants affecting the glomerular filtration rate. The identification of robust, reliable, and reproducible genetic markers for disease severity in SCA remains elusive, but new genetic variants provide avenues for further validation and investigation. PMID- 27711209 TI - The Association between Elevated Levels of Peripheral Serotonin and Its Metabolite - 5-Hydroxyindoleacetic Acid and Bone Strength and Metabolism in Growing Rats with Mild Experimental Chronic Kidney Disease. AB - Chronic kidney disease (CKD) is associated with disturbances in bone strength and metabolism. The alterations of the serotonergic system are also observed in CKD. We used the 5/6 nephrectomy model of CKD to assess the impact of peripheral serotonin and its metabolite- 5-hydroxyindoleacetic acid on bone biomechanical properties and metabolism in growing rats. The animals were sacrificed one and three months after nephrectomy. Biomechanical properties were determined on two different bone types: the cortical bone of the femoral diaphysis using three point bending test and the mixed cortico-trabecular bone by the bending test of the femoral neck. Biomechanical tests revealed preserved cortical bone strength, whereas work to fracture (W) and yield load (Fy) of mixed cortico-trabecular bone were significantly lower in CKD compared to controls. Serum activity of alkaline phosphatase (ALP), a bone formation marker, and tartrate-resistant acid phosphatase (TRACP 5b) reflecting bone resorption, were similar in CKD and controls. ALP was associated with lower femoral stiffness and strength, and higher displacements and W. TRACP 5b was inversely associated with cortical Fu and W. The elevated peripheral serotonergic system in CKD was: inversely associated with stiffness but positively related to the displacements and W; inversely associated with cortical Fy but positively correlated with this parameter in cortico-trabecular bone; inversely associated with ALP in controls but positively correlated with this biomarker in CKD animals. In conclusion, this study demonstrates the distinct effect of mild degree of CKD on bone strength in rapidly growing rats. The impaired renal function affects the peripheral serotonin metabolism, which in turn may influence the strength and metabolism of bones in these rats. This relationship seems to be beneficial on the biomechanical properties of the cortico-trabecular bone, whereas the cortical bone strength can be potentially reduced. PMID- 27711211 TI - Correlates of Unwanted Births in Bangladesh: A Study through Path Analysis. AB - BACKGROUND: Unwanted birth is an important public health concern due to its negative association with adverse outcomes of mothers and children as well as socioeconomic development of a country. Although a number of studies have been investigated the determinants of unwanted births through logistic regression analysis, an extensive assessment using path model is lacking. In the current study, we applied path analysis to know the important covariates for unwanted births in Bangladesh. METHODS: The study used data extracted from Bangladesh Demographic and Health Survey (BDHS) 2011. It considered sub-sample consisted of 7,972 women who had given most recent births five years preceding the date of interview or who were currently pregnant at survey time. Correlation analysis was used to find out the significant association with unwanted births. This study provided the factors affecting unwanted births in Bangladesh. The path model was used to determine the direct, indirect and total effects of socio-demographic factors on unwanted births. RESULTS: The result exhibited that more than one tenth of the recent births were unwanted in Bangladesh. The differentials of unwanted births were women's age, education, age at marriage, religion, socioeconomic status, exposure of mass-media and use of family planning. In correlation analysis, it showed that unwanted births were positively correlated with women age and place of residence and these relationships were significant. On the contrary, unwanted births were inversely significantly correlated with education and social status. The total effects of endogenous variables such as women age, place of residence and use of family planning methods had favorable effect on unwanted births. CONCLUSION: Policymakers and program planners need to design programs and services carefully to reduce unwanted births in Bangladesh, especially, service should focus on helping those groups of women who were identified in the analysis as being at increased risks of unwanted births- older women, illiterate, low socioeconomic status, early age at marriage and rural poor susceptible women. PMID- 27711210 TI - Signaling of Prostaglandin E Receptors, EP3 and EP4 Facilitates Wound Healing and Lymphangiogenesis with Enhanced Recruitment of M2 Macrophages in Mice. AB - Lymphangiogenesis plays an important role in homeostasis, metabolism, and immunity, and also occurs during wound-healing. Here, we examined the roles of prostaglandin E2 (PGE2) receptor (EP) signaling in enhancement of lymphangiogenesis in wound healing processes. The hole-punch was made in the ears of male C57BL/6 mice using a metal ear punch. Healing process and lymphangiogenesis together with macrophage recruitment were analyzed in EP knockout mice. Lymphangiogenesis was up-regulated in the granulation tissues at the margins of punched-hole wounds in mouse ears, and this increase was accompanied by increased expression levels of COX-2 and microsomal prostaglandin E synthase-1. Administration of celecoxib, a COX-2 inhibitor, suppressed lymphangiogenesis in the granulation tissues and reduced the induction of the pro lymphangiogenic factors, vascular endothelial growth factor (VEGF) -C and VEGF-D. Topical applications of selective EP receptor agonists enhanced the expressions of lymphatic vessel endothelial hyaluronan receptor-1 and VEGF receptor-3. The wound-healing processes and recruitment of CD11b-positive macrophages, which produced VEGF-C and VEGF-D, were suppressed under COX-2 inhibition. Mice lacking either EP3 or EP4 exhibited reduced wound-healing, lymphangiogenesis and recruitment of M2 macrophages, compared with wild type mice. Proliferation of cultured human lymphatic endothelial cells was not detected under PGE2 stimulation. Lymphangiogenesis and recruitment of M2 macrophages that produced VEGF-C/D were suppressed in mice treated with a COX-2 inhibitor or lacking either EP3 or EP4 during wound healing. COX-2 and EP3/EP4 signaling may be novel targets to control lymphangiogenesis in vivo. PMID- 27711212 TI - Fitting HIV Prevalence 1981 Onwards for Three Indian States Using the Goals Model and the Estimation and Projection Package. AB - Models are designed to provide evidence for strategic program planning by examining the impact of different interventions on projected HIV incidence. We employed the Goals Model to fit the HIV epidemic curves in Andhra Pradesh, Maharashtra and Tamil Nadu states of India where HIV epidemic is considered to have matured and in a declining phase. Input data in the Goals Model consisted of demographic, epidemiological, transmission-related and risk group wise behavioral parameters. The HIV prevalence curves generated in the Goals Model for each risk group in the three states were compared with the epidemic curves generated by the Estimation and Projection Package (EPP) that the national program is routinely using. In all the three states, the HIV prevalence trends for high-risk populations simulated by the Goals Model matched well with those derived using state-level HIV surveillance data in the EPP. However, trends for the low- and medium-risk populations differed between the two models. This highlights the need to generate more representative and robust data in these sub-populations and consider some structural changes in the modeling equation and parameters in the Goals Model to effectively use it to assess the impact of future strategies of HIV control in various sub-populations in India at the sub-national level. PMID- 27711213 TI - Determinants of Attitude toward the Public Health Spending and Its Relationship with Voting Behavior in the 2012 South Korean Presidential Election. AB - This study aimed to identify the factors influencing South Korean voters' attitudes towards increasing public expenditure on health and to identify whether the issue of healthcare expenditure influenced candidate choice in the 2012 Korean presidential election. The study used the data from a survey conducted by the Institute of Korean Politics at Seoul National University immediately following the 2012 presidential election. The survey was completed by a nationwide sample of 1,200 people aged 19 or over using a face-to-face interview method and proportional quota sampling based on sex, age, and region. About 44.3% of respondents had a positive attitude toward increasing public health expenditure. There was no significant difference by the candidate they supported (conservative Park Geun-hye or liberal Moon Jae-in). In particular, even 44.9% of conservative supporters agreed with more spending. Politically neutral respondents (OR = 1.76, 90% CI 1.22-2.54) and strong conservative party supporters (OR = 1.53, 90% CI 1.05-2.25) were more likely to support public health expenditure increase compared to strong liberal party supporters. Also, respondents who believed that the economic gap in the country was widening were 1.91 times more likely to support an increase in public health expenditures. However, the issue of health expenditure had no influence on voters' choice of presidential candidates, and in particular no negative effect of choice of the ruling (conservative) party's candidate. Our results should be interpreted with care; one possible reason for this lack of effect might be that constituents voted along partisan lines regardless of their attitude to the welfare issue; another possible explanation might be the success of the "left click strategy" of the conservative party. That is, the conservatives did not reject economic democratization or social welfare expansion. Further research should be done to explain why attitudes to health spending did not directly affect choice of candidate. PMID- 27711214 TI - Progressive Dystrophic Pathology in Diaphragm and Impairment of Cardiac Function in FKRP P448L Mutant Mice. AB - Mutations in the gene for fukutin-related protein represent a subset of muscular dystrophies known as dystroglycanopathies characterized by loss of functionally glycosylated-alpha-dystroglycan and a wide range of dystrophic phenotypes. Mice generated by our lab containing the P448L mutation in the fukutin-related protein gene demonstrate the dystrophic phenotype similar to that of LGMD2I. Here we examined the morphology of the heart and diaphragm, focusing on pathology of diaphragm and cardiac function of the mutant mice for up to 12 months. Both diaphragm and heart lack clear expression of functionally-glycosylated-alpha dystroglycan throughout the observed period. The diaphragm undergoes progressive deterioration in histology with increasing amount of centranucleation and inflammation. Large areas of mononuclear cell infiltration and fibrosis of up to 60% of tissue area were detected as early as 6 months of age. Despite a less severe morphology with only patches of mononuclear cell infiltration and fibrosis of ~5% by 12 months of age in the heart, cardiac function is clearly affected. High frequency ultrasound reveals a smaller heart size up to 10 months of age. There are significant increases in myocardial thickness and decrease in cardiac output through 12 months. Dysfunction in the heart represents a key marker for evaluating experimental therapies aimed at cardiac muscle. PMID- 27711215 TI - Heparanase Overexpression Reduces Hepcidin Expression, Affects Iron Homeostasis and Alters the Response to Inflammation. AB - Hepcidin is the key regulator of systemic iron availability that acts by controlling the degradation of the iron exporter ferroportin. It is expressed mainly in the liver and regulated by iron, inflammation, erythropoiesis and hypoxia. The various agents that control its expression act mainly via the BMP6/SMAD signaling pathway. Among them are exogenous heparins, which are strong hepcidin repressors with a mechanism of action not fully understood but that may involve the competition with the structurally similar endogenous Heparan Sulfates (HS). To verify this hypothesis, we analyzed how the overexpression of heparanase, the HS degrading enzyme, modified hepcidin expression and iron homeostasis in hepatic cell lines and in transgenic mice. The results showed that transient and stable overexpression of heparanase in HepG2 cells caused a reduction of hepcidin expression and of SMAD5 phosphorylation. Interestingly, the clones showed also altered level of TfR1 and ferritin, indices of a modified iron homeostasis. The heparanase transgenic mice showed a low level of liver hepcidin, an increase of serum and liver iron with a decrease in spleen iron content. The hepcidin expression remained surprisingly low even after treatment with the inflammatory LPS. The finding that modification of HS structure mediated by heparanase overexpression affects hepcidin expression and iron homeostasis supports the hypothesis that HS participate in the mechanisms controlling hepcidin expression. PMID- 27711216 TI - A Link No Longer Missing: New Evidence for the Cetotheriid Affinities of Caperea. AB - The origins of the enigmatic pygmy right whale Caperea marginata, the only living member of its subfamily (Neobalaeninae), are an outstanding mystery of cetacean evolution. Its strikingly disparate morphology sets Caperea apart from all other whales, and has turned it into a wildcard taxon that holds the key to understanding modern baleen whale diversity. Morphological cladistics generally ally this species with right whales, whereas molecular analyses consistently cluster it with rorquals and grey whales (Balaenopteroidea). A recent study potentially resolved this conflict by proposing that Caperea belongs with the otherwise extinct Cetotheriidae, but has been strongly criticised on morphological grounds. Evidence from the neobalaenine fossil record could potentially give direct insights into morphological transitions, but is currently limited to just a single species: the Late Miocene Miocaperea pulchra, from Peru. We show that Miocaperea has a highly unusual morphology of the auditory region, resulting from a-presumably feeding-related-strengthening of the articulation of the hyoid apparatus with the skull. This distinctive arrangement is otherwise only found in the extinct Cetotheriidae, which makes Miocaperea a "missing link" that demonstrates the origin of pygmy right whales from cetotheriids, and confirms the latter's resurrection from the dead. PMID- 27711218 TI - Behavioural and Psychiatric Phenotypes in Men and Boys with X-Linked Ichthyosis: Evidence from a Worldwide Online Survey. AB - BACKGROUND: X-linked ichthyosis (XLI) is a rare dermatological condition arising from deficiency for the enzyme steroid sulfatase (STS). Preliminary evidence in boys with XLI, and animal model studies, suggests that individuals lacking STS are at increased risk of developmental disorders and associated traits. However, the behavioural profile of children with XLI is poorly-characterised, and the behavioural profile of adults with XLI has not yet been documented at all. MATERIALS AND METHODS: Using an online survey, advertised worldwide, we collected detailed self- or parent-reported information on behaviour in adult (n = 58) and younger (<=18yrs, n = 24) males with XLI for comparison to data from their non affected brothers, and age/gender-matched previously-published normative data. The survey comprised demographic and background information (including any prior clinical diagnoses) and validated questionnaires assaying phenotypes of particular interest (Adult ADHD Self-Report Scale v1.1, Barrett Impulsiveness Scale-11, adult and adolescent Autism Quotient, Kessler Psychological Distress Scales, and Disruptive Behaviour Disorder Rating Scale). RESULTS: Individuals with XLI generally exhibited normal sensory function. Boys with XLI were at increased risk of developmental disorder, whilst adults with the condition were at increased risk of both developmental and mood disorders. Both adult and younger XLI groups scored significantly more highly than male general population norms on measures of inattention, impulsivity, autism-related traits, psychological distress and disruptive behavioural traits. CONCLUSIONS: These findings indicate that both adult and younger males with XLI exhibit personality profiles that are distinct from those of males within the general population, and suggest that individuals with XLI may be at heightened risk of psychopathology. The data are consistent with the notion that STS is important in neurodevelopment and ongoing brain function, and with previous work suggesting high rates of developmental disorders in boys with XLI. Our results suggest that individuals with XLI may require medical care from multidisciplinary teams, and should help to inform genetic counselling for the condition. PMID- 27711217 TI - Multi-Functional OCT Enables Longitudinal Study of Retinal Changes in a VLDLR Knockout Mouse Model. AB - We present a multi-functional optical coherence tomography (OCT) imaging approach to study retinal changes in the very-low-density-lipoprotein-receptor (VLDLR) knockout mouse model with a threefold contrast. In the retinas of VLDLR knockout mice spontaneous retinal-chorodoidal neovascularizations form, having an appearance similar to choroidal and retinal neovascularizations (CNV and RNV) in neovascular age-related macular degeneration (AMD) or retinal angiomatous proliferation (RAP). For this longitudinal study, the mice were imaged every 4 to 6 weeks starting with an age of 4 weeks and following up to the age of 11 months. Significant retinal changes were identified by the multi-functional imaging approach offering a threefold contrast: reflectivity, polarization sensitivity (PS) and motion contrast based OCT angiography (OCTA). By use of this intrinsic contrast, the long-term development of neovascularizations was studied and associated processes, such as the migration of melanin pigments or retinal choroidal anastomosis, were assessed in vivo. Furthermore, the in vivo imaging results were validated with histological sections at the endpoint of the experiment. Multi-functional OCT proves as a powerful tool for longitudinal retinal studies in preclinical research of ophthalmic diseases. Intrinsic contrast offered by the functional extensions of OCT might help to describe regulative processes in genetic animal models and potentially deepen the understanding of the pathogenesis of retinal diseases such as wet AMD. PMID- 27711219 TI - Assessing Basal and Acute Autophagic Responses in the Adult Drosophila Nervous System: The Impact of Gender, Genetics and Diet on Endogenous Pathway Profiles. AB - The autophagy pathway is critical for the long-term homeostasis of cells and adult organisms and is often activated during periods of stress. Reduced pathway efficacy plays a central role in several progressive neurological disorders that are associated with the accumulation of cytotoxic peptides and protein aggregates. Previous studies have shown that genetic and transgenic alterations to the autophagy pathway impacts longevity and neural aggregate profiles of adult Drosophila. In this study, we have identified methods to measure the acute in vivo induction of the autophagy pathway in the adult fly CNS. Our findings indicate that the genotype, age, and gender of adult flies can influence pathway responses. Further, we demonstrate that middle-aged male flies exposed to intermittent fasting (IF) had improved neuronal autophagic profiles. IF-treated flies also had lower neural aggregate profiles, maintained more youthful behaviors and longer lifespans, when compared to ad libitum controls. In summary, we present methodology to detect dynamic in vivo changes that occur to the autophagic profiles in the adult Drosophila CNS and that a novel IF-treatment protocol improves pathway response in the aging nervous system. PMID- 27711221 TI - Enlargement of the Axial Length and Altered Ultrastructural Features of the Sclera in a Mutant Lumican Transgenic Mouse Model. AB - Lumican (LUM) is a candidate gene for myopia in the MYP3 locus. In this study, a mutant lumican (L199P) transgenic mouse model was established to investigate the axial length changes and ultrastructural features of the sclera. The mouse model was established by pronuclear microinjection. Transgenic mice and wild-type B6 mice were killed at eight weeks of age. Gene expression levels of LUM and collagen type I (COL1) in the sclera were analyzed by quantitative real-time polymerase chain reaction (qPCR), and the protein levels were assessed by Western blot analysis. Ocular axial lengths were measured on the enucleated whole eye under a dissecting microscope. Ultrastructural features of collagen fibrils in the sclera were examined with transmission electron microscopy (TEM). Lumican and collagen type I were both elevated at the transcriptional and protein levels. The mean axial length of eyes in the transgenic mice was significantly longer than that in the wild-type mice (3,231.0 +/- 11.2 MUm (transgenic group) vs 3,199.7 +/ 11.1 MUm (controls), p<0.05 =). Some ultrastructural changes were observed in the sclera of the transgenic mice under TEM, such as evident lamellar disorganizations and abnormal inter-fibril spacing. The average collagen fibril diameter was smaller than that in their wild-type counterparts. These results indicate that the ectopic mutant lumican (L199P) may induce enlargement of axial lengths and abnormal structures and distributions of collagen fibrils in mouse sclera. This transgenic mouse model can be used for the mechanistic study of myopia. PMID- 27711220 TI - Acute Infectious Gastroenteritis Potentiates a Crohn's Disease Pathobiont to Fuel Ongoing Inflammation in the Post-Infectious Period. AB - Crohn's disease (CD) is a chronic inflammatory condition of diverse etiology. Exposure to foodborne pathogens causing acute gastroenteritis produces a long term risk of CD well into the post-infectious period but the mechanistic basis for this ongoing relationship to disease onset is unknown. We developed two novel models to study the comorbidity of acute gastroenteritis caused by Salmonella Typhimurium or Citrobacter rodentium in mice colonized with adherent-invasive Escherichia coli (AIEC), a bacterial pathobiont linked to CD. Here, we show that disease activity in the post-infectious period after gastroenteritis is driven by the tissue-associated expansion of the resident AIEC pathobiont, with an attendant increase in immunopathology, barrier defects, and delays in mucosal restitution following pathogen clearance. These features required AIEC resistance to host defense peptides and a fulminant inflammatory response to the enteric pathogen. Our results suggest that individuals colonized by AIEC at the time of acute infectious gastroenteritis may be at greater risk for CD onset. Importantly, our data identify AIEC as a tractable disease modifier, a finding that could be exploited in the development of therapeutic interventions following infectious gastroenteritis in at-risk individuals. PMID- 27711222 TI - Association between Traffic Air Pollution and Reduced Forced Vital Capacity: A Study Using Personal Monitors for Outdoor Workers. AB - BACKGROUND: The effects of outdoor air pollution on lung function in adults are still controversial. OBJECTIVE: Evaluate the effects of exposure to different levels of traffic-generated PM2.5 on workers' lung functions in Sao Paulo, Brazil. METHODS: To cover a wide range of exposures, 101 non-smoking workers from three occupations (taxi drivers, traffic controllers, and forest rangers) were selected for the study. After clinical evaluation, the participants were scheduled to attend four consecutive weekly visits in which they received a 24 hour personal PM2.5 sampler and had lung function tests measured on the following day. The association between the spirometric variables and the averaged PM2.5 levels was assessed using robust regression models adjusted for age, waist circumference, time at the job, daily work hours, diabetes or hypertension and former smoking habits. RESULTS: Relative to workers in the lowest exposed group (all measures < 25 MUg/m3), those with the highest level of exposure (all measures > 39.6 MUg/m3) showed a reduction of predicted FVC (-12.2%; CI 95%: [ 20.0% to -4.4%]), a marginal reduction of predicted FEV1 (-9.1%; CI 95%: [-19.1% to 0.9%]) and an increase of predicted FEF25-75%/FVC (14.9%; CI 95%: [2.9% to 26.8%]) without changes of FEV1/FVC. CONCLUSIONS: Exposure to vehicular traffic air pollution is associated with a small but significant reduction of FVC without a reduction of FEV1/FVC. PMID- 27711223 TI - The Bacterial Mfd Protein Prevents DNA Damage Induced by the Host Nitrogen Immune Response in a NER-Independent but RecBC-Dependent Pathway. AB - Production of reactive nitrogen species is an important component of the host immune defence against bacteria. Here, we show that the bacterial protein Mfd (Mutation frequency decline), a highly conserved and ubiquitous bacterial protein involved in DNA repair, confers bacterial resistance to the eukaryotic nitrogen response produced by macrophage cells and during mice infection. In addition, we show that RecBC is also necessary to survive this stress. The inactivation of recBC and mfd genes is epistatic showing that Mfd follows the RecBC repair pathway to protect the bacteria against the genotoxic effect of nitrite. Surprisingly given the role of Mfd in transcription-coupled repair, UvrA is not necessary to survive the nitrite response. Taken together, our data reveal that during the eukaryotic nitrogen response, Mfd is required to maintain bacterial genome integrity in a NER-independent but RecBC-dependent pathway. PMID- 27711224 TI - Benzodiazepine Use During Hospitalization: Automated Identification of Potential Medication Errors and Systematic Assessment of Preventable Adverse Events. AB - OBJECTIVE: Benzodiazepines and "Z-drug" GABA-receptor modulators (BDZ) are among the most frequently used drugs in hospitals. Adverse drug events (ADE) associated with BDZ can be the result of preventable medication errors (ME) related to dosing, drug interactions and comorbidities. The present study evaluated inpatient use of BDZ and related ME and ADE. METHODS: We conducted an observational study within a pharmacoepidemiological database derived from the clinical information system of a tertiary care hospital. We developed algorithms that identified dosing errors and interacting comedication for all administered BDZ. Associated ADE and risk factors were validated in medical records. RESULTS: Among 53,081 patients contributing 495,813 patient-days BDZ were administered to 25,626 patients (48.3%) on 115,150 patient-days (23.2%). We identified 3,372 patient-days (2.9%) with comedication that inhibits BDZ metabolism, and 1,197 (1.0%) with lorazepam administration in severe renal impairment. After validation we classified 134, 56, 12, and 3 cases involving lorazepam, zolpidem, midazolam and triazolam, respectively, as clinically relevant ME. Among those there were 23 cases with associated adverse drug events, including severe CNS-depression, falls with subsequent injuries and severe dyspnea. Causality for BDZ was formally assessed as 'possible' or 'probable' in 20 of those cases. Four cases with ME and associated severe ADE required administration of the BDZ antagonist flumazenil. CONCLUSIONS: BDZ use was remarkably high in the studied setting, frequently involved potential ME related to dosing, co-medication and comorbidities, and rarely cases with associated ADE. We propose the implementation of automated ME screening and validation for the prevention of BDZ-related ADE. PMID- 27711225 TI - Keratin 13 Is Enriched in Prostate Tubule-Initiating Cells and May Identify Primary Prostate Tumors that Metastasize to the Bone. AB - BACKGROUND: Benign human prostate tubule-initiating cells (TIC) and aggressive prostate cancer display common traits, including tolerance of low androgen levels, resistance to apoptosis, and microenvironment interactions that drive epithelial budding and outgrowth. TIC can be distinguished from epithelial and stromal cells that comprise prostate tissue via cell sorting based upon Epcam, CD44, and CD49f antigenic profiles. Fetal prostate epithelial cells (FC) possess a similar antigenic profile to adult TIC and are capable of inducing tubule formation. To identify the TIC niche in human prostate tissue, differential keratin (KRT) expression was evaluated. RESULTS: Gene expression data generated from Affymetrix Gene Chip human U133 Plus 2.0 array of sorted adult and fetal epithelial cells revealed KRT13 to be significantly enriched in FC and TIC compared to basal cells (BC) and luminal cells (LC) (p<0.001). Enriched KRT13 expression was confirmed by RT-PCR and cytospin immunostaining. Immunohistochemical analysis of KRT13 expression revealed rare KRT13+ epithelia throughout prostatic ducts/acini in adult tissue specimens and differentiated tubules in 24-week recombinant grafts, In contrast, abundant KRT13 expression was observed in developing ducts/acini in fetal prostate and cord-like structures composing 8-week recombinant grafts. Immunostaining of a prostate tissue microarray revealed KRT13+ tumor foci in approximately 9% of cases, and this subset displayed significantly shorter time to recurrence (p = 0.031), metastases (p = 0.032), and decreased overall survival (p = 0.004). Diagnostic prostate needle biopsies (PNBX) from untreated patients with concurrent bone metastases (clinical stage M1) displayed KRT13+ tumor foci, as did bone metastatic foci. CONCLUSIONS: The expression profile of KRT13 in benign fetal and adult prostate tissue and in recombinant grafts, as well as the frequency of KRT13 expression in primary and metastatic prostate cancer indicates that it may be a marker of a stem/progenitor-like cell state that is co-opted in aggressive tumor cells. KRT13 is enriched in benign stem-like cells that display androgen-resistance, apoptosis resistance, and branching morphogenesis properties. Collectively our data demonstrate that KRT13 expression is associated with poor prognosis at multiple stages of disease progression and may represent an important biomarker of adverse outcome in patients with prostate cancer.

AB - Embryo implantation requires synchronized dialogue between the receptive endometrium and activated blastocyst via locally produced soluble mediators. During the mid-secretory (MS) phase of the menstrual cycle, increased glandular secretion into the uterine lumen provides important mediators that modulate the endometrium and support the conceptus during implantation. Previously we demonstrated the importance of vascular endothelial growth factor (VEGF) in the human uterus, particularly with respect to embryo implantation. In the current study, proteomic analysis of human uterine lavage fluid identified the presence of placental growth factor (PlGF) a homolog of VEGF, that binds the VEGF receptor 1 (VEGFR1). Analysis of immunostaining for PlGF in human endometrial tissue across the menstrual cycle (from both fertile and infertile women) revealed PlGF was predominantly localised to glandular and luminal epithelial cells, with staining in the decidualising stromal cells surrounding the maternal spiral arteries in the secretory phase of the menstrual cycle. Immunoreactive PlGF was also detected in subpopulations of endometrial leukocytes. Functional studies demonstrated that culturing mouse embryos with recombinant human (rh)PlGF enhanced blastocyst cell number and outgrowth. Furthermore, treatment of human endometrial epithelial cells (EEC) with rhPlGF enhanced EEC adhesion. Taken together, these data demonstrate that PlGF is abundant in the human endometrium, and secreted into the uterine lumen where it mediates functional changes in cellular adhesion with important roles in implantation.

AB - Mesenchymal stem cells (MSCs) have innate ability to self-renew and immunosuppressive functions, and differentiate into various cell types. They have become a promising cell source for treating many diseases, particular for bone regeneration. Osteoporosis is a common metabolic bone disorder with elevated systemic inflammation which in turn triggers enhanced bone loss. We hypothesize that systemic infusion of MSCs may suppress the elevated inflammation in the osteoporotic subjects and slow down bone loss. The current project was to address the following two questions: (1) Will a single dose systemic administration of allogenic MSCs have any effect on osteoporotic bone loss? (2) Will multiple administration of allogenic MSCs from single or multiple donors have similar effect on osteoporotic bone loss? 18 ovariectomized (OVX) rats were assigned into 3 groups: the PBS control group, MSCs group 1 (receiving 2x106 GFP-MSCs at Day 10, 46, 91 from the same donor following OVX) and MSCs group 2 (receiving 2x106 GFP-MSCs from three different donors at Day 10, 46, 91). Examinations included Micro-CT, serum analysis, mechanical testing, immunofluorescence staining and bone histomorphometry analysis. Results showed that BV/TV at Day 90, 135, BMD of TV and trabecular number at Day 135 in the PBS group were significantly higher than those in the MSCs group 2, whereas trabecular spacing at Day 90, 135 was significantly smaller than that in MSCs group 2. Mechanical testing data didn't show significant difference among the three groups. In addition, the ELISA assay showed that level of Rantes in serum in MSCs group 2 was significantly higher than that of the PBS group, whereas IL-6 and IL-10 were significantly lower than those of the PBS group. Bone histomorphometry analysis showed that Oc.S/BS and Oc.N/BS in the PBS group were significant lower than those in MSCs group 2; Ob.S/BS and Ob.N/BS did not show significant difference among the three groups. The current study demonstrated that systemic administration of allogenic MSCs had no obvious effect on osteoporotic bone loss in OVX rats when using the cells from the same donor; and repeated injection of allogeneic MSCs from different donors might promote bone loss in OVX rats. These findings indicate that despite allogenic MSCs systemic infusion is safe, their administration alone may not be an effective mean for preventing osteoporotic bone loss.

AB - : GV-TH-01, a Phase 1 open-label trial of a DNA prime-Modified Vaccinia Ankara (MVA) boost vaccine (GOVX-B11), was undertaken in HIV infected participants on antiretroviral treatment (ART) to evaluate safety and vaccine-elicited T cell responses, and explore the ability of elicited CD8+ T cells to control viral rebound during analytical treatment interruption (TI). Nine men who began antiretroviral therapy (ART) within 18 months of seroconversion and had sustained plasma HIV-1 RNA <50 copies/mL for at least 6 months were enrolled. Median age was 38 years, median pre-ART HIV-1 RNA was 140,000 copies/ml and mean baseline CD4 count was 755/MUl. Two DNA, followed by 2 MVA, inoculations were given 8 weeks apart. Eight subjects completed all vaccinations and TI. Clinical and laboratory adverse events were generally mild, with no serious or grade 4 events. Only reactogenicity events were considered related to study drug. No treatment emergent viral resistance was seen. The vaccinations did not reduce viral reservoirs and virus re-emerged in all participants during TI, with a median time to re-emergence of 4 weeks. Eight of 9 participants had CD8+ T cells that could be stimulated by vaccine-matched Gag peptides prior to vaccination. Vaccinations boosted these responses as well as eliciting previously undetected CD8+ responses. Elicited T cells did not display signs of exhaustion. During TI, temporal patterns of viral re-emergence and Gag-specific CD8+ T cell expansion suggested that vaccine-specific CD8+ T cells had been stimulated by re-emergent virus in only 2 of 8 participants. In these 2, transient decreases in viremia were associated with Gag selection in known CD8+ T cell epitopes. We hypothesize that escape mutations, already archived in the viral reservoir, plus a poor ability of CD8+ T cells to traffic to and control virus at sites of re-emergence, limited the therapeutic efficacy of the DNA/MVA vaccine.

AB - The goal of bottom-up synthetic biology culminates in the assembly of an entire cell from separate biological building blocks. One major challenge resides in the in vitro production and implementation of complex genetic and metabolic pathways that can support essential cellular functions. Here, we show that phospholipid biosynthesis, a multiple-step process involved in cell membrane homeostasis, can be reconstituted starting from the genes encoding for all necessary proteins. A total of eight E. coli enzymes for acyl transfer and headgroup modifications were produced in a cell-free gene expression system and were co-translationally reconstituted in liposomes. Acyl-coenzyme A and glycerol-3-phosphate were used as canonical precursors to generate a variety of important bacterial lipids. Moreover, this study demonstrates that two-step acyl transfer can occur from enzymes synthesized inside vesicles. Besides clear implications for growth and potentially division of a synthetic cell, we postulate that gene-based lipid biosynthesis can become instrumental for ex vivo and protein purification-free production of natural and non-natural lipids. PMID- 27711231 TI - Comprehensive Retinal Image Analysis for Aggressive Posterior Retinopathy of Prematurity. AB - Computer aided analysis plays a nontrivial role in assisting the diagnosis of various eye pathologies. In this paper, we propose a framework to help diagnose the presence of Aggressive Posterior Retinopathy Of Prematurity (APROP), a pathology that is characterised by rapid onset and increased tortuosity of blood vessels close to the optic disc (OD). We quantify vessel characteristics that are of clinical relevance to APROP such as tortuosity and the extent of branching i.e., vessel segment count in the defined diagnostic region. We have adapted three vessel segmentation techniques: matched filter response, scale space theory and morphology with local entropy based thresholding. The proposed feature set equips us to build a linear discriminant classifier to discriminate APROP images from clinically healthy images. We have studied 36 images from 21 APROP subjects against a control group of 15 clinically healthy age matched infants. All subjects are age matched ranging from 33-40 weeks of post menstrual age. Experimental results show that we attain 100% recall and 95.45% precision, when the vessel network obtained from morphology is used for feature extraction. PMID- 27711230 TI - The Role of Hepatitis C Virus Core Antigen Testing in the Era of Direct Acting Antiviral Therapies: What We Can Learn from the Protease Inhibitors. AB - Direct-acting antiviral (DAA) therapies have revolutionised the treatment of hepatitis C virus (HCV). The financial cost of DAAs however is significant, and first generation protease inhibitors (PIs) also require frequent monitoring of viral RNA levels to guide treatment. In this context, we examined the relevance of HCV antigen testing to evaluate the potential role in monitoring virological response to HCV antiviral treatment with the PI-based triple therapies, telaprevir (TVR) and boceprevir (BOC). Chronic HCV-infected individuals (n = 152) enrolled in the Irish Hepatitis C Outcomes Research Network (ICORN) study were prospectively analysed for baseline markers and the early viral kinetics associated with SVR. The sustained virological response (SVR) rates in the cohort receiving TVR and BOC were 87.3% and 73.8%, respectively. Baseline factors associated with successful outcome in TVR therapy were age (P = 0.0098), IFNL3 genotype (P = 0.0330) and viral load (P = 0.0456). RNA level at week 4 (P = 0.0068) and viral antigen negativity at week 2 (P = 0.0359) were predictive of SVR for TVR-based therapy. In BOC therapy, prior interferon treatment (P = 0.0209) and IFNL3 genotype (P = 0.0410) were baseline predictors of SVR. Evidence of viraemia based either on viral RNA or antigen at week 4 predicted SVR in these patients. Our data showed that rapid decline of HCV antigen to negative level at week 2 in TVR treatment and <0.96 log fmol/l in BOC treatment after commencement of PI triple therapy were associated with SVR. HCV antigen measurement should be considered as a potential alternative for monitoring treatment response during DAA-based regimens. PMID- 27711232 TI - Self-Contained Statistical Analysis of Gene Sets. AB - Microarrays are a powerful tool for studying differential gene expression. However, lists of many differentially expressed genes are often generated, and unraveling meaningful biological processes from the lists can be challenging. For this reason, investigators have sought to quantify the statistical probability of compiled gene sets rather than individual genes. The gene sets typically are organized around a biological theme or pathway. We compute correlations between different gene set tests and elect to use Fisher's self-contained method for gene set analysis. We improve Fisher's differential expression analysis of a gene set by limiting the p-value of an individual gene within the gene set to prevent a small percentage of genes from determining the statistical significance of the entire set. In addition, we also compute dependencies among genes within the set to determine which genes are statistically linked. The method is applied to T-ALL (T-lineage Acute Lymphoblastic Leukemia) to identify differentially expressed gene sets between T-ALL and normal patients and T-ALL and AML (Acute Myeloid Leukemia) patients. PMID- 27711233 TI - Sterol Regulatory Element Binding Protein (Srb1) Is Required for Hypoxic Adaptation and Virulence in the Dimorphic Fungus Histoplasma capsulatum. AB - The Histoplasma capsulatum sterol regulatory element binding protein (SREBP), Srb1 is a member of the basic helix-loop-helix (bHLH), leucine zipper DNA binding protein family of transcription factors that possess a unique tyrosine (Y) residue instead of an arginine (R) residue in the bHLH region. We have determined that Srb1 message levels increase in a time dependent manner during growth under oxygen deprivation (hypoxia). To further understand the role of Srb1 during infection and hypoxia, we silenced the gene encoding Srb1 using RNA interference (RNAi); characterized the resulting phenotype, determined its response to hypoxia, and its ability to cause disease within an infected host. Silencing of Srb1 resulted in a strain of H. capsulatum that is incapable of surviving in vitro hypoxia. We found that without complete Srb1 expression, H. capsulatum is killed by murine macrophages and avirulent in mice given a lethal dose of yeasts. Additionally, silencing Srb1 inhibited the hypoxic upregulation of other known H. capsulatum hypoxia-responsive genes (HRG), and genes that encode ergosterol biosynthetic enzymes. Consistent with these regulatory functions, Srb1 silenced H. capsulatum cells were hypersensitive to the antifungal azole drug itraconazole. These data support the theory that the H. capsulatum SREBP is critical for hypoxic adaptation and is required for H. capsulatum virulence. PMID- 27711234 TI - A Virtual Reality Full Body Illusion Improves Body Image Disturbance in Anorexia Nervosa. AB - BACKGROUND: Patients with anorexia nervosa (AN) have a persistent distorted experience of the size of their body. Previously we found that the Rubber Hand Illusion improves hand size estimation in this group. Here we investigated whether a Full Body Illusion (FBI) affects body size estimation of body parts more emotionally salient than the hand. In the FBI, analogue to the RHI, participants experience ownership over an entire virtual body in VR after synchronous visuo-tactile stimulation of the actual and virtual body. METHODS AND RESULTS: We asked participants to estimate their body size (shoulders, abdomen, hips) before the FBI was induced, directly after induction and at ~2 hour 45 minutes follow-up. The results showed that AN patients (N = 30) decrease the overestimation of their shoulders, abdomen and hips directly after the FBI was induced. This effect was strongest for estimates of circumference, and also observed in the asynchronous control condition of the illusion. Moreover, at follow-up, the improvements in body size estimation could still be observed in the AN group. Notably, the HC group (N = 29) also showed changes in body size estimation after the FBI, but the effect showed a different pattern than that of the AN group. CONCLUSION: The results lead us to conclude that the disturbed experience of body size in AN is flexible and can be changed, even for highly emotional body parts. As such this study offers novel starting points from which new interventions for body image disturbance in AN can be developed. PMID- 27711235 TI - Transcriptome Profile of the Chicken Thrombocyte: New Implications as an Advanced Immune Effector Cell. AB - Thrombocytes are nucleated platelets involved in immune functions such as pathogen recognition and release of pro-inflammatory bioactive compounds when exposed to bacterial and viral molecules. However, the complete role of these cells in innate and adaptive immune responses is not understood, and little is known about their biology at the molecular-genetic level. Highly sensitive RNA sequencing technologies were used to analyze the complete transcriptome of thrombocytes for the first time with analytical resolution focused on cell-based components of the immune system/response. Amongst all the genes listed in the current chicken genome assembly, 10,041 gene transcripts were found in the chicken thrombocyte. After 1-hour in vitro stimulation with lipopolysaccharide (LPS, Salmonella minnesota), 490 genes were upregulated and 359 genes were downregulated, respectively, with at least a 1-fold change relative to unexposed thrombocytes. Additionally, by constructing a de novo assembly, we were able to identify a total of 3,030 novel genes in the thrombocyte transcriptome. The information generated here is useful in development of novel solutions to lower the economic burden and zoonotic threat that accompanies infectious diseases for birds and fish. In addition, the resources created here have translational utility as a model system to find orthologous genes and genes related to its enucleated counterpart, the platelet. PMID- 27711236 TI - An Examination of Not-For-Profit Stakeholder Networks for Relationship Management: A Small-Scale Analysis on Social Media. AB - Using a small-scale descriptive network analysis approach, this study highlights the importance of stakeholder networks for identifying valuable stakeholders and the management of existing stakeholders in the context of mental health not-for profit services. We extract network data from the social media brand pages of three health service organizations from the U.S., U.K., and Australia, to visually map networks of 579 social media brand pages (represented by nodes), connected by 5,600 edges. This network data is analyzed using a collection of popular graph analysis techniques to assess the differences in the way each of the service organizations manage stakeholder networks. We also compare node meta information against basic topology measures to emphasize the importance of effectively managing relationships with stakeholders who have large external audiences. Implications and future research directions are also discussed. PMID- 27711237 TI - Proteomic Analysis Implicates Dominant Alterations of RNA Metabolism and the Proteasome Pathway in the Cellular Response to Carbon-Ion Irradiation. AB - Radiotherapy with heavy ions is considered advantageous compared to irradiation with photons due to the characteristics of the Braggs peak and the high linear energy transfer (LET) value. To understand the mechanisms of cellular responses to different LET values and dosages of heavy ion radiation, we analyzed the proteomic profiles of mouse embryo fibroblast MEF cells exposed to two doses from different LET values of heavy ion 12C. Total proteins were extracted from these cells and examined by Q Exactive with Liquid Chromatography (LC)-Electrospray Ionization (ESI) Tandem MS (MS/MS). Using bioinformatics approaches, differentially expressed proteins with 1.5 or 2.0-fold changes between different dosages of exposure were compared. With the higher the dosage and/or LET of ion irradiation, the worse response the cells were in terms of protein expression. For instance, compared to the control (0 Gy), 771 (20.2%) proteins in cells irradiated at 0.2 Gy of carbon-ion radiation with 12.6 keV/MUm, 313 proteins (8.2%) in cells irradiated at 2 Gy of carbon-ion radiation with 12.6 keV/MUm, and 243 proteins (6.4%) in cells irradiated at 2 Gy of carbon-ion radiation with 31.5 keV/MUm exhibited changes of 1.5-fold or greater. Gene ontology (GO) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, Munich Information Center for Protein Sequences (MIPS) analysis, and BioCarta analysis all indicated that RNA metabolic processes (RNA splicing, destabilization and deadenylation) and proteasome pathways may play key roles in the cellular response to heavy-ion irradiation. Proteasome pathways ranked highest among all biological processes associated with heavy carbon-ion irradiation. In addition, network analysis revealed that cellular pathways involving proteins such as Col1a1 and Fn1 continued to respond to high dosages of heavy-ion irradiation, suggesting that these pathways still protect cells against damage. However, pathways such as those involving Ikbkg1 responded better at lower dosages than at higher dosages, implying that cell damage would occur when the networks involving these proteins stop responding. Our investigation provides valuable proteomic information for elucidating the mechanism of biological effects induced by carbon ions in general. PMID- 27711238 TI - The Highly Selective and Near-Quantitative Conversion of Glucose to 5 Hydroxymethylfurfural Using Ionic Liquids. AB - A number of ionic liquids have been shown to be excellent solvents for lignocellulosic biomass processing, and some of these are particularly effective in the production of the versatile chemical building block 5 hydroxymethylfurfural (HMF). In this study, the production of HMF from the simple sugar glucose in ionic liquid media is discussed. Several aspects of the selective catalytic formation of HMF from glucose have been elucidated using metal halide salts in two distinct ionic liquids, 1-butyl-3-methylimidazolium chloride and 1-butyl-3-methylimidazolium hydrogen sulfate as well as mixtures of these, revealing key features for accelerating the desired reaction and suppressing byproduct formation. The choice of ionic liquid anion is revealed to be of particular importance, with low HMF yields in the case of hydrogen sulfate based salts, which are reported to be effective for HMF production from fructose. The most successful system investigated in this study led to almost quantitative conversion of glucose to HMF (90% in only 30 minutes using 7 mol% catalyst loading at 120 degrees C) in a system which is selective for the desired product, has low energy intensity and is environmentally benign. PMID- 27711239 TI - Hemizygous Deletion on Chromosome 3p26.1 Is Associated with Heavy Smoking among African American Subjects in the COPDGene Study. AB - Many well-powered genome-wide association studies have identified genetic determinants of self-reported smoking behaviors and measures of nicotine dependence, but most have not considered the role of structural variants, such as copy number variation (CNVs), influencing these phenotypes. Here, we included 2,889 African American and 6,187 non-Hispanic White subjects from the COPDGene cohort (http://www.copdgene.org) to carefully investigate the role of polymorphic CNVs across the genome on various measures of smoking behavior. We identified a CNV component (a hemizygous deletion) on chromosome 3p26.1 associated with two quantitative phenotypes related to smoking behavior among African Americans. This polymorphic hemizygous deletion is significantly associated with pack-years and cigarettes smoked per day among African American subjects in the COPDGene study. We sought evidence of replication in African Americans from the population based Atherosclerosis Risk in Communities (ARIC) study. While we observed similar CNV counts, the extent of exposure to cigarette smoking among ARIC subjects was quite different and the smaller sample size of heavy smokers in ARIC severely limited statistical power, so we were unable to replicate our findings from the COPDGene cohort. But meta-analyses of COPDGene and ARIC study subjects strengthened our association signal. However, a few linkage studies have reported suggestive linkage to the 3p26.1 region, and a few genome-wide association studies (GWAS) have reported markers in the gene (GRM7) nearest to this 3p26.1 area of polymorphic deletions are associated with measures of nicotine dependence among subjects of European ancestry. PMID- 27711240 TI - Reference Ranges and Association of Age and Lifestyle Characteristics with Testosterone, Sex Hormone Binding Globulin, and Luteinizing Hormone among 1166 Western Chinese Men. AB - Decreased total testosterone (TT) is the recommended metric to identify age related hypogonadism. However, average TT and the extent to which it varies by age, can vary substantially among different populations. Population-specific reference ranges are needed to understand normal versus abnormal TT levels. Therefore, the goal for this study was to describe androgen concentrations and their correlates among Western Chinese men. We completed a population-based, cross-sectional study including 227 young adults (YA) (20-39 years) and 939 older adults (OA) (40-89 years). We measured TT, sex-hormone binding globulin (SHBG), luteinizing hormone (LH), testosterone secreting index (TSI), and calculated free testosterone (cFT). Reference ranges for this population were determined using average YA concentrations. Multivariable regression models were used to predict hormone concentrations adjusting for age, waist-to-height ratio (WHR), marital status, education, occupation, smoking, alcohol, blood glucose, and blood pressure. Among OA, 3.8% had low TT, 15.2% had low cFT, 26.3% had low TSI, 21.6% had high SHBG, and 6.1% had high LH. Average cFT was significantly lower in OA (0.30 nmol/L; standard deviation (SD): 0.09) versus YA (0.37; SD: 0.11) but TT was not different in OA (16.82 nmol/L; SD: 4.80) versus YA (16.88; SD: 5.29). In adjusted models increasing age was significantly associated with increased SHBG or LH, and decreased cFT or TSI; however, TT was not significantly associated with age (beta = 0.02 nmol/L; 95% confidence interval (CI): -0.01, 0.04). Higher WHR was associated with significantly decreased TT, SHBG, TSI, and LH. The only variable significantly related to cFT was age (beta = -0.0033; 95% CI:-0.0037, 0.0028); suggesting that cFT measurements would not be confounded by other lifestyle factors. In conclusion, cFT, but not TT, varies with age in this population, suggesting cFT may be a better potential marker for age-related androgen deficiency than TT among Western Chinese men. PMID- 27711241 TI - Population Genetic Structure of Glycyrrhiza inflata B. (Fabaceae) Is Shaped by Habitat Fragmentation, Water Resources and Biological Characteristics. AB - BACKGROUND: Habitat fragmentation, water resources and biological characteristics are important factors that shape the genetic structure and geographical distribution of desert plants. Analysis of the relationships between these factors and population genetic variation should help to determine the evolutionary potential and conservation strategies for genetic resources for desert plant populations. As a traditional Chinese herb, Glycyrrhiza inflata B. (Fabaceae) is restricted to the fragmented desert habitat in China and has undergone a dramatic decline due to long-term over-excavation. Determining the genetic structure of the G. inflata population and identifying a core collection could help with the development of strategies to conserve this species. RESULTS: We investigated the genetic variation of 25 G. inflata populations based on microsatellite markers. A high level of population genetic divergence (FST = 0.257), population bottlenecks, reduced gene flow and moderate genetic variation (HE = 0.383) were detected. The genetic distances between the populations significantly correlated with the geographical distances, and this suggests that habitat fragmentation has driven a special genetic structure of G. inflata in China through isolation by distance. STRUCTURE analysis showed that G. inflata populations were structured into three clusters and that the populations belonged to multiple water systems, which suggests that water resources were related to the genetic structure of G. inflata. In addition, the biological characteristics of the perennial species G. inflata, such as its long-lived seeds, asexual reproduction, and oasis ecology, may be related to its resistance to habitat fragmentation. A core collection of G. inflata, that included 57 accessions was further identified, which captured the main allelic diversity of G. inflata. CONCLUSIONS: Recent habitat fragmentation has accelerated genetic divergence. The population genetic structure of G. inflata has been shaped by habitat fragmentation, water resources and biological characteristics. This genetic information and core collection will facilitate the conservation of wild germplasm and breeding of this Chinese medicinal plant. PMID- 27711242 TI - Developing the Stroke Exercise Preference Inventory (SEPI). AB - BACKGROUND: Physical inactivity is highly prevalent after stroke, increasing the risk of poor health outcomes including recurrent stroke. Tailoring of exercise programs to individual preferences can improve adherence, but no tools exist for this purpose in stroke. METHODS: We identified potential questionnaire items for establishing exercise preferences via: (i) our preliminary Exercise Preference Questionnaire in stroke, (ii) similar tools used in other conditions, and (iii) expert panel consultations. The resulting 35-item questionnaire (SEPI-35) was administered to stroke survivors, along with measures of disability, depression, anxiety, fatigue and self-reported physical activity. Exploratory factor analysis was used to identify a factor structure in exercise preferences, providing a framework for item reduction. Associations between exercise preferences and personal characteristics were analysed using multivariable regression. RESULTS: A group of 134 community-dwelling stroke survivors (mean age 64.0, SD 13.3) participated. Analysis of the SEPI-35 identified 7 exercise preference factors (Supervision-support, Confidence-challenge, Health-wellbeing, Exercise context, Home-alone, Similar others, Music-TV). Item reduction processes yielded a 13-item version (SEPI-13); in analysis of this version, the original factor structure was maintained. Lower scores on Confidence-challenge were significantly associated with disability (p = 0.002), depression (p = 0.001) and fatigue (p = 0.001). Self reported barriers to exercise were particularly prevalent in those experiencing fatigue and anxiety. CONCLUSIONS: The SEPI-13 is a brief instrument that allows assessment of exercise preferences and barriers in the stroke population. This new tool can be employed by health professionals to inform the development of individually tailored exercise interventions. PMID- 27711244 TI - Is the Taklimakan Desert Highway Shelterbelt Sustainable to Long-Term Drip Irrigation with High Saline Groundwater? AB - Freshwater resources are scarce in desert regions. Highly saline groundwater of different salinity is being used to drip irrigate the Taklimakan Desert Highway Shelterbelt with a double-branch-pipe system controlling the irrigation cycles. In this study, to evaluate the dynamics of soil moisture and salinity under the current irrigation system, soil samples were collected to a 2-m depth in the shelterbelt planted for different years and irrigated with different groundwater salinities, and soil moisture and salinity were analyzed. The results showed that both depletion of soil moisture and increase of topsoil salinity occurred simultaneously during one irrigation cycle. Soil moisture decreased from 27.4% to 2.4% for a 15-day irrigation cycle and from 26.4% to 2.7% for a 10-day-cycle, respectively. Topsoil electrical conductivity (EC) increased from 0.64 to 3.32 dS/m and 0.70 to 3.99 dS/m for these two irrigation cycles. With increased shelterbelt age, profiled average soil moisture (0-200 cm) reduced from 12.8% (1 year) to 7.1% (10-year); however, soil moisture in 0-20-cm increased, while topsoil salinity decreased. In addition, irrigation salinity mainly affected soil salinity in the 0-20-cm range. We conclude that water supply with the double branch-pipe is a feasible irrigation method for the Taklimakan Desert Highway Shelterbelt, and our findings provide a model for shelterbelt construction and sustainable management when using highly saline water for irrigation in analogous habitats. PMID- 27711243 TI - cGMP-Dependent Protein Kinase Inhibition Extends the Upper Temperature Limit of Stimulus-Evoked Calcium Responses in Motoneuronal Boutons of Drosophila melanogaster Larvae. AB - While the mammalian brain functions within a very narrow range of oxygen concentrations and temperatures, the fruit fly, Drosophila melanogaster, has employed strategies to deal with a much wider range of acute environmental stressors. The foraging (for) gene encodes the cGMP-dependent protein kinase (PKG), has been shown to regulate thermotolerance in many stress-adapted species, including Drosophila, and could be a potential therapeutic target in the treatment of hyperthermia in mammals. Whereas previous thermotolerance studies have looked at the effects of PKG variation on Drosophila behavior or excitatory postsynaptic potentials at the neuromuscular junction (NMJ), little is known about PKG effects on presynaptic mechanisms. In this study, we characterize presynaptic calcium ([Ca2+]i) dynamics at the Drosophila larval NMJ to determine the effects of high temperature stress on synaptic transmission. We investigated the neuroprotective role of PKG modulation both genetically using RNA interference (RNAi), and pharmacologically, to determine if and how PKG affects presynaptic [Ca2+]i dynamics during hyperthermia. We found that PKG activity modulates presynaptic neuronal Ca2+ responses during acute hyperthermia, where PKG activation makes neurons more sensitive to temperature-induced failure of Ca2+ flux and PKG inhibition confers thermotolerance and maintains normal Ca2+ dynamics under the same conditions. Targeted motoneuronal knockdown of PKG using RNAi demonstrated that decreased PKG expression was sufficient to confer thermoprotection. These results demonstrate that the PKG pathway regulates presynaptic motoneuronal Ca2+ signaling to influence thermotolerance of presynaptic function during acute hyperthermia. PMID- 27711246 TI - Fault Diagnosis for Rotating Machinery: A Method based on Image Processing. AB - Rotating machinery is one of the most typical types of mechanical equipment and plays a significant role in industrial applications. Condition monitoring and fault diagnosis of rotating machinery has gained wide attention for its significance in preventing catastrophic accident and guaranteeing sufficient maintenance. With the development of science and technology, fault diagnosis methods based on multi-disciplines are becoming the focus in the field of fault diagnosis of rotating machinery. This paper presents a multi-discipline method based on image-processing for fault diagnosis of rotating machinery. Different from traditional analysis method in one-dimensional space, this study employs computing method in the field of image processing to realize automatic feature extraction and fault diagnosis in a two-dimensional space. The proposed method mainly includes the following steps. First, the vibration signal is transformed into a bi-spectrum contour map utilizing bi-spectrum technology, which provides a basis for the following image-based feature extraction. Then, an emerging approach in the field of image processing for feature extraction, speeded-up robust features, is employed to automatically exact fault features from the transformed bi-spectrum contour map and finally form a high-dimensional feature vector. To reduce the dimensionality of the feature vector, thus highlighting main fault features and reducing subsequent computing resources, t-Distributed Stochastic Neighbor Embedding is adopt to reduce the dimensionality of the feature vector. At last, probabilistic neural network is introduced for fault identification. Two typical rotating machinery, axial piston hydraulic pump and self-priming centrifugal pumps, are selected to demonstrate the effectiveness of the proposed method. Results show that the proposed method based on image processing achieves a high accuracy, thus providing a highly effective means to fault diagnosis for rotating machinery.

AB - BACKGROUND: A consistent association has been reported between low socioeconomic status (SES) and cardiovascular events (CE), whereas the association between SES and cerebrovascular events (CBVD) is less clear. The aim of this study was to investigate the association between SES (measured using education) and CE/CBVD in a cohort study, as well as to investigate lifestyle and clinical risk factors, to help to clarify the mechanisms by which SES influences CE/CBVD. MATERIAL AND METHODS: We searched for diagnoses of CE and CBVD in the clinical records of 47,749 members of the EPICOR cohort (average follow-up time: 11 years). SES was determined by the relative index of inequality (RII). RESULTS: A total of 1,156 CE and 468 CBVD were found in the clinical records. An increased risk of CE was observed in the crude Cox model for the third tertile of RII compared to the first tertile (hazard ratio [HR] = 1.39; 95% confidence interval [CI] 1.21-1.61). The increased risk persisted after adjustment for lifestyle risk factors (HR = 1.19; 95%CI 1.02-1.38), clinical risk factors (HR = 1.35; 95%CI 1.17-1.56), and after full adjustment (HR = 1.17; 95%CI 1.01-1.37). Structural equation model showed that lifestyle rather than clinical risk factors are involved in the mechanisms by which education influences CE. No significant association was found between education and CBVD. A strong relationship was observed between education and diabetes at baseline. CONCLUSION: The most important burden of inequality in CE incidence in Italy is due to lifestyle risk factors.

AB - Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a disabling autoimmune disorder of the peripheral nervous system (PNS). Intravenous immunoglobulins (IVIg) are effective in CIDP, but the treatment response varies greatly between individual patients. Understanding this interindividual variability and predicting the response to IVIg constitute major clinical challenges in CIDP. We previously established intercellular adhesion molecule (ICAM)-1 deficient non-obese diabetic (NOD) mice as a novel animal model of CIDP. Here, we demonstrate that similar to human CIDP patients, ICAM-1 deficient NOD mice respond to IVIg treatment by clinical and histological measures. Nerve magnetic resonance imaging and histology demonstrated that IVIg ameliorates abnormalities preferentially in distal parts of the sciatic nerve branches. The IVIg treatment response also featured great heterogeneity allowing us to identify IVIg responders and non-responders. An increased production of interleukin (IL) 17 positively predicted IVIg treatment responses. In human sural nerve biopsy sections, high numbers of IL-17 producing cells were associated with younger age and shorter disease duration. Thus, our novel animal model can be utilized to identify prognostic markers of treatment responses in chronic inflammatory neuropathies and we identify IL-17 production as one potential such prognostic marker.

AB - Tetrahydrobiopterin (BH4) is an essential cofactor of nitric oxide synthase (NOS) and aromatic amino acid hydroxylases. BH4 and 7,8-dihydrobiopterin (BH2) are metabolically interchangeable at the expense of NADPH. Exogenously administered BH4 can be metabolized by the body, similar to vitamins. At present, synthetic BH4 is used as an orphan drug for patients with inherited diseases requiring BH4 supplementation. BH4 supplementation has also drawn attention as a means of treating certain cardiovascular symptoms, however, its application in human patients remains limited. Here, we tracked biopterin (BP) distribution in blood, bile, urine, liver, kidney and brain after BH4 administration (5 mg/kg rat, i.v.) with or without prior treatment with probenecid, a potent inhibitor of uptake transporters particularly including organic anion transporter families such as OTA1 and OAT3. The rapid excretion of BP in urine was driven by elevated blood concentrations and its elimination reached about 90% within 120 min. In the very early period, BP was taken up by the liver and kidney and gradually released back to the blood. BH4 administration caused a considerable decrease in the BH4% in blood BP as an inevitable compensatory process. Probenecid treatment slowed down the decrease in blood BP and simultaneously inhibited its initial rapid excretion in the kidney. At the same time, the BH4% was further lowered, suggesting that the probenecid-sensitive BP uptake played a crucial role in BH2 scavenging in vivo. This suggested that the overproduced BH2 was taken up by organs by means of the probenecid-sensitive process, and was then scavenged by counter-conversion to BH4 via the BH4 salvage pathway. Taken together, BH4 administration was effective at raising BP levels in organs over the course of hours but with extremely low efficiency. Since a high BH2 relative to BH4 causes NOS dysfunction, the lowering of the BH4% must be avoided in practice, otherwise the desired effect of the supplementation in ameliorating NOS dysfunction would be spoiled.

AB - INTRODUCTION: Childhood Obsessive-Compulsive Disorder (OCD) is a prevalent and impairing condition that can be effectively treated with Cognitive Behavior Therapy (CBT). However, a majority of children and adolescents do not have access to CBT. Internet-delivered CBT (ICBT) has been suggested as a way to increase availability to effective psychological treatments. Yet, the research on ICBT in children and adolescents has been lagging behind significantly both when it comes to quantitative as well as qualitative studies. The aim of the current study was to describe the experience of ICBT in adolescents with OCD. METHOD: Eight adolescents with OCD that had received ICBT were interviewed with qualitative methodology regarding their experiences of the intervention. Data was summarized into thematic categories. RESULTS: Two overarching themes were identified, autonomy and support, each consisting of three primary themes (self-efficacy, flexibility, secure self-disclosure and clinician support, parental support, identification/normalization, respectively). CONCLUSIONS: The experiential hierarchical model that was identified in this study is, in part, transferrable to previous research. In addition, it highlights the need of further study of important process variables of ICBT in young patient populations. PMID- 27711250 TI - Five-Year Antimicrobial Resistance Patterns of Urinary Escherichia coli at an Australian Tertiary Hospital: Time Series Analyses of Prevalence Data. AB - This study describes the antimicrobial resistance temporal trends and seasonal variation of Escherichia coli (E. coli) urinary tract infections (UTIs) over five years, from 2009 to 2013, and compares prevalence of resistance in hospital- and community-acquired E. coli UTI. A cross sectional study of E. coli UTIs from patients attending a tertiary referral hospital in Canberra, Australia was undertaken. Time series analysis was performed to illustrate resistance trends. Only the first positive E. coli UTI per patient per year was included in the analysis. A total of 15,022 positive cultures from 8724 patients were identified. Results are based on 5333 first E. coli UTIs, from 4732 patients, of which 84.2% were community-acquired. Five-year hospital and community resistance rates were highest for ampicillin (41.9%) and trimethoprim (20.7%). Resistance was lowest for meropenem (0.0%), nitrofurantoin (2.7%), piperacillin-tazobactam (2.9%) and ciprofloxacin (6.5%). Resistance to amoxycillin-clavulanate, cefazolin, gentamicin and piperacillin-tazobactam were significantly higher in hospital- compared to community-acquired UTIs (9.3% versus 6.2%; 15.4% versus 9.7%; 5.2% versus 3.7% and 5.2% versus 2.5%, respectively). Trend analysis showed significant increases in resistance over five years for amoxycillin-clavulanate, trimethoprim, ciprofloxacin, nitrofurantoin, trimethoprim-sulphamethoxazole, cefazolin, ceftriaxone and gentamicin (P<0.05, for all) with seasonal pattern observed for trimethoprim resistance (augmented Dickey-Fuller statistic = 4.136; P = 0.006). An association between ciprofloxacin resistance, cefazolin resistance and ceftriaxone resistance with older age was noted. Given the relatively high resistance rates for ampicillin and trimethoprim, these antimicrobials should be reconsidered for empirical treatment of UTIs in this patient population. Our findings have important implications for UTI treatment based on setting of acquisition. PMID- 27711251 TI - A Comparison of the Costs and Benefits of Bacterial Gene Expression. AB - To study how a bacterium allocates its resources, we compared the costs and benefits of most (86%) of the proteins in Escherichia coli K-12 during growth in minimal glucose medium. The cost or investment in each protein was estimated from ribosomal profiling data, and the benefit of each protein was measured by assaying a library of transposon mutants. We found that proteins that are important for fitness are usually highly expressed, and 95% of these proteins are expressed at above 13 parts per million (ppm). Conversely, proteins that do not measurably benefit the host (with a benefit of less than 5% per generation) tend to be weakly expressed, with a median expression of 13 ppm. In aggregate, genes with no detectable benefit account for 31% of protein production, or about 22% if we correct for genetic redundancy. Although some of the apparently unnecessary expression could have subtle benefits in minimal glucose medium, the majority of the burden is due to genes that are important in other conditions. We propose that at least 13% of the cell's protein is "on standby" in case conditions change. PMID- 27711253 TI - HSPB1 Enhances SIRT2-Mediated G6PD Activation and Promotes Glioma Cell Proliferation. AB - Heat shock proteins belong to a conserved protein family and are involved in multiple cellular processes. Heat shock protein 27 (Hsp27), also known as heat HSPB1, participates in cellular responses to not only heat shock, but also oxidative or chemical stresses. However, the contribution of HSPB1 to anti oxidative response remains unclear. Here, we show that HSPB1 activates G6PD in response to oxidative stress or DNA damage. HSPB1 enhances the binding between G6PD and SIRT2, leading to deacetylation and activation of G6PD. Besides, HSPB1 activates G6PD to sustain cellular NADPH and pentose production in glioma cells. High expression of HSPB1 correlates with poor survivalrate of glioma patients. Together, our study uncovers the molecular mechanism by which HSPB1 activates G6PD to protect cells from oxidative and DNA damage stress. PMID- 27711252 TI - PG1058 Is a Novel Multidomain Protein Component of the Bacterial Type IX Secretion System. AB - Porphyromonas gingivalis utilises the Bacteroidetes-specific type IX secretion system (T9SS) to export proteins across the outer membrane (OM), including virulence factors such as the gingipains. The secreted proteins have a conserved carboxy-terminal domain essential for type IX secretion that is cleaved upon export. In P. gingivalis the T9SS substrates undergo glycosylation with anionic lipopolysaccharide (A-LPS) and are attached to the OM. In this study, comparative analyses of 24 Bacteroidetes genomes identified ten putative novel components of the T9SS in P. gingivalis, one of which was PG1058. Computer modelling of the PG1058 structure predicted a novel N- to C-terminal architecture comprising a tetratricopeptide repeat (TPR) domain, a beta-propeller domain, a carboxypeptidase regulatory domain-like fold (CRD) and an OmpA_C-like putative peptidoglycan binding domain. Inactivation of pg1058 in P. gingivalis resulted in loss of both colonial pigmentation and surface-associated proteolytic activity; a phenotype common to T9SS mutants. Immunoblot and LC-MS/MS analyses of subcellular fractions revealed T9SS substrates accumulated within the pg1058 mutant periplasm whilst whole-cell ELISA showed the Kgp gingipain was absent from the cell surface, confirming perturbed T9SS function. Immunoblot, TEM and whole-cell ELISA analyses indicated A-LPS was produced and present on the pg1058 mutant cell surface although it was not linked to T9SS substrate proteins. This indicated that PG1058 is crucial for export of T9SS substrates but not for the translocation of A-LPS. PG1058 is a predicted lipoprotein and was localised to the periplasmic side of the OM using whole-cell ELISA, immunoblot and LC-MS/MS analyses of subcellular fractions. The structural prediction and localisation of PG1058 suggests that it may have a role as an essential scaffold linking the periplasmic and OM components of the T9SS. PMID- 27711254 TI - Reversible Cryopreservation of Living Cells Using an Electron Microscopy Cryo Fixation Method. AB - Rapid cooling of aqueous solutions is a useful approach for two important biological applications: (I) cryopreservation of cells and tissues for long-term storage, and (II) cryofixation for ultrastructural investigations by electron and cryo-electron microscopy. Usually, both approaches are very different in methodology. Here we show that a novel, fast and easy to use cryofixation technique called self-pressurized rapid freezing (SPRF) is-after some adaptations also a useful and versatile technique for cryopreservation. Sealed metal tubes with high thermal diffusivity containing the samples are plunged into liquid cryogen. Internal pressure builds up reducing ice crystal formation and therefore supporting reversible cryopreservation through vitrification of cells. After rapid rewarming of pressurized samples, viability rates of > 90% can be reached, comparable to best-performing of the established rapid cooling devices tested. In addition, the small SPRF tubes allow for space-saving sample storage and the sealed containers prevent contamination from or into the cryogen during freezing, storage, or thawing. PMID- 27711255 TI - Scaffold Role of DUSP22 in ASK1-MKK7-JNK Signaling Pathway. AB - Mitogen-activated protein kinases (MAPKs) are involved in a variety of intracellular events such as gene expression, cell proliferation, and programmed cell death. MAPKs are activated by dual phosphorylation on threonine and tyrosine residues through sequential activation of protein kinases. Recent studies have shown that the protein kinases involved in MAPK signal transductions might be organized into signaling complexes by scaffold proteins. These scaffold proteins are essential regulators that function by assembling the relevant molecular components in mammalian cells. In this study, we report that dual-specificity phosphatase 22 (DUSP22), a member of the protein tyrosine phosphatase family, acts as a distinct scaffold protein in c-Jun N-terminal kinase (JNK) signaling. DUSP22 increased the phosphorylation in the activation loop of JNK regardless of its phosphatase activity but had no effect on phosphorylation levels of ERK and p38 in mammalian cells. Furthermore, DUSP22 selectively associated with apoptosis signal-regulating kinase 1 (ASK1), MAPK kinase 7 (MKK7), and JNK1/2. Both JNK phosphorylation and JNK-mediated apoptosis increased in a concentration-dependent manner regardless of DUSP22 phosphatase activity at low DUSP22 concentrations, but then decreased at higher DUSP22 concentrations, which is the prominent feature of a scaffold protein. Thus, our data suggest that DUSP22 regulates cell death by acting as a scaffold protein for the ASK1-MKK7-JNK signal transduction pathway independently of its phosphatase activity. PMID- 27711256 TI - The Effect of Gender on Mesenchymal Stem Cell (MSC) Efficacy in Neonatal Hyperoxia-Induced Lung Injury. AB - BACKGROUND: Mesenchymal stem cells (MSC) improve alveolar and vascular structures in experimental models of bronchopulmonary dysplasia (BPD). Female MSC secrete more anti-inflammatory and pro-angiogenic factors as compared to male MSC. Whether the therapeutic efficacy of MSC in attenuating lung injury in an experimental model of BPD is influenced by the sex of the donor MSC or recipient is unknown. Here we tested the hypothesis that female MSC would have greater lung regenerative properties than male MSC in experimental BPD and this benefit would be more evident in males. OBJECTIVE: To determine whether intra-tracheal (IT) administration of female MSC to neonatal rats with experimental BPD has more beneficial reparative effects as compared to IT male MSC. METHODS: Newborn Sprague-Dawley rats exposed to normoxia (RA) or hyperoxia (85% O2) from postnatal day (P) 2- P21 were randomly assigned to receive male or female IT bone marrow (BM)-derived green fluorescent protein (GFP+) MSC (1 x 106 cells/50 MUl), or Placebo on P7. Pulmonary hypertension (PH), vascular remodeling, alveolarization, and angiogenesis were assessed at P21. PH was determined by measuring right ventricular systolic pressure (RVSP) and pulmonary vascular remodeling was evaluated by quantifying the percentage of muscularized peripheral pulmonary vessels. Alveolarization was evaluated by measuring mean linear intercept (MLI) and radial alveolar count (RAC). Angiogenesis was determined by measuring vascular density. Data are expressed as mean +/- SD, and analyzed by ANOVA. RESULTS: There were no significant differences in the RA groups. Exposure to hyperoxia resulted in a decrease in vascular density and RAC, with a significant increase in MLI, RVSP, and the percentage of partially and fully muscularized pulmonary arterioles. Administration of both male and female MSC significantly improved vascular density, alveolarization, RVSP, percent of muscularized vessels and alveolarization. Interestingly, the improvement in PH and vascular remodeling was more robust in the hyperoxic rodents who received MSC from female donors. In keeping with our hypothesis, male animals receiving female MSC, had a greater improvement in vascular remodeling. This was accompanied by a more significant decrease in lung pro-inflammatory markers and a larger increase in anti inflammatory and pro-angiogenic markers in male rodents that received female MSC. There were no significant differences in MSC engraftment among groups. CONCLUSIONS: Female BM-derived MSC have greater therapeutic efficacy than male MSC in reducing neonatal hyperoxia-induced lung inflammation and vascular remodeling. Furthermore, the beneficial effects of female MSC were more pronounced in male animals. Together, these findings suggest that female MSC maybe the most potent BM-derived MSC population for lung repair in severe BPD complicated by PH.

PMID- 27711259 TI - Recent Progress in Self-Supported Metal Oxide Nanoarray Electrodes for Advanced Lithium-Ion Batteries. AB - The rational design and fabrication of electrode materials with desirable architectures and optimized properties has been demonstrated to be an effective approach towards high-performance lithium-ion batteries (LIBs). Although nanostructured metal oxide electrodes with high specific capacity have been regarded as the most promising alternatives for replacing commercial electrodes in LIBs, their further developments are still faced with several challenges such as poor cycling stability and unsatisfying rate performance. As a new class of binder-free electrodes for LIBs, self-supported metal oxide nanoarray electrodes have many advantageous features in terms of high specific surface area, fast electron transport, improved charge transfer efficiency, and free space for alleviating volume expansion and preventing severe aggregation, holding great potential to solve the mentioned problems. This review highlights the recent progress in the utilization of self-supported metal oxide nanoarrays grown on 2D planar and 3D porous substrates, such as 1D and 2D nanostructure arrays, hierarchical nanostructure arrays, and heterostructured nanoarrays, as anodes and cathodes for advanced LIBs. Furthermore, the potential applications of these binder-free nanoarray electrodes for practical LIBs in full-cell configuration are outlined. Finally, the future prospects of these self-supported nanoarray electrodes are discussed.

PMID- 27711263 TI - A Safer Sodium-Ion Battery Based on Nonflammable Organic Phosphate Electrolyte. AB - Sodium-ion batteries are now considered as a low-cost alternative to lithium-ion technologies for large-scale energy storage applications; however, their safety is still a matter of great concern for practical applications. In this paper, a safer sodium-ion battery is proposed by introducing a nonflammable phosphate electrolyte (trimethyl phosphate, TMP) coupled with NaNi0.35Mn0.35Fe0.3O2 cathode and Sb-based alloy anode. The physical and electrochemical compatibilities of the TMP electrolyte are investigated by igniting, ionic conductivity, cyclic voltammetry, and charge-discharge measurements. The results exhibit that the TMP electrolyte with FEC additive is completely nonflammable and has wide electrochemical window (0-4.5 V vs. Na/Na+), in which both the Sb-based anode and NaNi0.35Mn0.35Fe0.3O2 cathode show high reversible capacity and cycling stability, similarly as in carbonate electrolyte. Based on these results, a nonflammable sodium-ion battery is constructed by use of Sb anode, NaNi0.35Mn0.35Fe0.3O2 cathode, and TMP + 10 vol% FEC electrolyte, which works very well with considerable capacity and cyclability, demonstrating a promising prospect to build safer sodium-ion batteries for large-scale energy storage applications.

PMID- 27711266 TI - Beyond Traditional RAFT: Alternative Activation of Thiocarbonylthio Compounds for Controlled Polymerization. AB - Recent developments in polymerization reactions utilizing thiocarbonylthio compounds have highlighted the surprising versatility of these unique molecules. The increasing popularity of reversible addition-fragmentation chain transfer (RAFT) radical polymerization as a means of producing well-defined, 'controlled' synthetic polymers is largely due to its simplicity of implementation and the availability of a wide range of compatible reagents. However, novel modes of thiocarbonylthio activation can expand the technique beyond the traditional system (i.e., employing a free radical initiator) pushing the applicability and use of thiocarbonylthio compounds even further than previously assumed. The primary advances seen in recent years are a revival in the direct photoactivation of thiocarbonylthio compounds, their activation via photoredox catalysis, and their use in cationic polymerizations. These synthetic approaches and their implications for the synthesis of controlled polymers represent a significant advance in polymer science, with potentially unforeseen benefits and possibilities for further developments still ahead. This Research News aims to highlight key works in this area while also clarifying the differences and similarities of each system. PMID- 27711267 TI - High-Performance Polymer Solar Cells Based on a Wide-Bandgap Polymer Containing Pyrrolo[3,4-f]benzotriazole-5,7-dione with a Power Conversion Efficiency of 8.63. AB - A novel donor-acceptor type conjugated polymer based on a building block of 4,8 di(thien-2-yl)-6-octyl-2-octyl-5H-pyrrolo[3,4-f]benzotriazole-5,7(6H)-dione (TZBI) as the acceptor unit and 4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)-benzo-[1,2 b:4,5-b']dithiophene as the donor unit, named as PTZBIBDT, is developed and used as an electron-donating material in bulk-heterojunction polymer solar cells. The resulting copolymer exhibits a wide bandgap of 1.81 eV along with relatively deep highest occupied molecular orbital energy level of -5.34 eV. Based on the optimized processing conditions, including thermal annealing, and the use of a water/alcohol cathode interlayer, the single-junction polymer solar cell based on PTZBIBDT:PC71BM ([6,6]-phenyl-C71-butyric acid methyl ester) blend film affords a power conversion efficiency of 8.63% with an open-circuit voltage of 0.87 V, a short circuit current of 13.50 mA cm-2, and a fill factor of 73.95%, which is among the highest values reported for wide-bandgap polymers-based single-junction organic solar cells. The morphology studies on the PTZBIBDT:PC71BM blend film indicate that a fibrillar network can be formed and the extent of phase separation can be mani-pulated by thermal annealing. These results indicate that the TZBI unit is a very promising building block for the synthesis of wide bandgap polymers for high-performance single-junction and tandem (or multijunction) organic solar cells.

PMID- 27711279 TI - Microsecond resolution of cavitation bubble dynamics using a high-speed electrochemical impedance approach. AB - A new method to detect the uncompensated resistance, the capacitance and the Faradaic current at an electrode exposed to ultrasonic cavitation is presented. The method enables these parameters to be resolved with a 2 microsecond resolution and relies on the detection of the impedance of an electrode recorded as a function of time with a suitable AC excitation signal (here 500 kHz). Data obtained from an aluminium electrode, held under potentiostatic control, is used to illustrate the technique with particular relevance to the effects of cavitation bubbles generated by ultrasound. Analysis of the data recorded shows that the cavitation bubbles form close to the surface of the electrode and collapse, causing damage to the passive film formed at the aluminium surface. The capacitance, uncompensated resistance and Faradaic signals are used to explore the dynamic processes and show expansion and collapse of bubbles prior to erosion/corrosion. The close proximity of the bubbles to the surface is deduced from the reductions in capacitance and increases in resistance prior to bubble collapse, which is then shown to trigger the onset of a Faradaic signal, thus confirming the erosion/corrosion mechanism previously assumed.

AB - The first Pd-catalyzed Mizoroki-Heck-type reaction of [Ph2SRfn][OTf] with alkenes is described. The reaction of [Ph2SRfn][OTf] (Rfn = CF3, CH2CF3) with alkenes in the presence of 10 mol% Pd[P(t-Bu)3]2 and TsOH at room temperature provided the corresponding phenylation products in good to high yields.

PMID- 27711296 TI - Crystals on the move: mechanical effects in dynamic solids. AB - When exposed to external stimuli such as heat or light, certain single crystals can acquire momentum and undergo motion. On a molecular scale, the motility of such dynamic single crystals is triggered by a phase transition or chemical reaction without gaseous products, and macroscopically manifests as either slow (reversible or irreversible) deformation, or as rapid, almost instantaneous propulsion of the crystals that is oftentimes accompanied by disintegration. While the elastic energy of the slow reconfiguration processes such as bending, twisting and coiling can be utilized for actuation of other objects, the fast disintegrative processes could be exploited to initiate pressure-sensitive applications. This short review intends to summarize recent developments in the growing research on dynamic crystals, especially aspects of the mechanism of rapid motion of thermosalient and photosalient (leaping) crystals. The collective evidence indicates that these solids are organic-based analogues of the inorganic martensitic materials. While qualitative explanation of the molecular processes that lead to the related dynamic phenomena can be provided, quantification of their kinematics, estimation of the useful work that can be extracted, and prediction of their occurrence are yet to be established. Harnessing the potential of these materials to rapidly and efficiently perform the fundamentally important process of transduction of heat or light into kinetic energy appears as a prospective basis for their application in motion gears and devices.

PMID- 27711312 TI - Simple rules and the emergence of complexity in surface chirality. AB - Surface chirality arising from self-organized molecular monolayers may manifest both a handedness and footedness, leading to a dual level of chiral expression. Recent advances have determined both levels of chirality at the single-molecule level and, surprisingly, reveal a plethora of chiral orderings. There is yet no clear understanding of why such varied manifestations of interface chirality occur. Here, we show that the ordering of handedness and footedness of amino acids within (n* 2) assemblies on Cu(110) may be understood on the basis of three simple generic rules from which a variety chiral expressions naturally arise. These rules also provide insights into how enantiomer assembly at surfaces may be tailored to produce required chiral organizations and segregations.

PMID- 27711325 TI - Supramolecular metallogels with bulk self-healing properties prepared by in situ metal complexation. AB - In this feature article, we discuss a series of contributions dealing with the in situ fabrication of supramolecular metallogels (i.e. using low molecular weight ligands and metal ions) that show self-healing properties of the bulk gel phase after complete physical segregation. Most of the advances in this area have taken place during the last three years and are mainly represented by organogels, whereas examples of hydrogels and organic-aqueous gels are still a minority. In situ gelation via metal-coordination of low molecular weight compounds is conceptually different from the use of premade (e.g. in solution) coordination polymers and polymeric structures as gelators and ligands, respectively. In the case of in situ gelation, the cooperative effects of all components of the mixture (i.e. ligand, metal ion, counterions and solvent molecules) in an appropriate ratio under well-defined experimental conditions play a crucial role in the gelation phenomenon and self-healing properties of the material.

AB - A novel hierarchical porous carbon-carbon nanotube hybrid (HPCC) is prepared using a one-step strategy that uses nickel nanoparticles as the template for pore formation and at the same time, as the catalyst for carbon nanotube (CNT) growth. Such a structure can not only store sulfur in the micro- and mesopores, which restrict the shuttling of polysulfides, but also ensure good electrical conductivity of the whole system due to the incorporation of CNTs. The hierarchical porous structure also ensures fast mass transportation. These factors effectively guarantee the high electrochemical performance of sulfur stored in this carbon in lithium-sulfur batteries.

The significance of the protocol has been further highlighted by exhibition of functionality tolerance along with a late-stage modification of the branched olefinated products leading to the formation of other functionalized molecules.

AB - RbCl and CsCl react with BrF3 yielding the corresponding decafluoridotribromates(iii), MBr3F10 (M = Rb, Cs), which were structurally characterized for the first time. The Br3F10- anion is surprisingly not linear but contains a MU3-bridging fluorine atom and seems to be the first example of MU3-F bridging of Br atoms. The compounds are highly reactive and cannot be handled in glassware. As for the tetrafluoridobromates themselves, they are powerful oxidizers and thus suitable for the dry-chemical recycling of precious metals and additionally feature a significantly higher BrF3 content.

The tyrosinase-mediated oxidation of the Tyr residue in a fluorescently labeled peptide may lead to efficient fluorescence quenching, while the tyrosine kinase-catalyzed phosphorylation of the peptide can prevent the Tyr oxidation and thus maintain strong fluorescence. PMID- 27711351 TI - Superior electrochemical performance of N-doped nanocrystalline FeF3/C with a single-step solid-state process. AB - FeF3 is a promising cathode material for lithium ion batteries but its poor electronic conductivity makes it non-practical. Here, we significantly improve the electrochemical activity of FeF3 by reducing the strong ionic character of Fe F with the replacement of some F with N atoms. N-doped nanocrystalline FeF3/C achieves the best electrochemical performance among FeF3 compounds reported to date: ~95 mA h g-1 at 21.1C discharge rate for 250 cycles. The results illustrate that the poor electronic conductivity of metal fluorides can be controlled by doping and this enables FeF3 or metal fluorides to be practically utilized in possible applications including energy conversion and storage.

AB - The facile heterodehydrocoupling of a range of primary or secondary amines and even ammonia with pinacolborane (HBPin) was accomplished using {ArMe6Sn(MU-OMe)}2 (1, ArMe6 = C6H3-2,6-(C6H2-2,4,6-Me3)2) as pre-catalysts for a catalytically active tin(ii) hydride. The more sterically hindered pre-catalyst 2, {AriPr4Sn(MU OMe)}2 (AriPr4 = C6H3-2,6-(C6H3-2,6-iPr2)2) facilitated the dehydrocoupling only of primary amines with HBPin, and at an increased rate relative to the less crowded {ArMe6Sn(MU-OMe)}2. Also presented is {ArMe6Sn(MU-NEt2)}2 (3), which can be converted into the structurally characterizable {ArMe6Sn(MU-NEt2)(MU H)SnArMe6} (4) via the addition of pinacol borane.

PMID- 27711369 TI - The growth and thermal properties of Au deposited on Rh(111): formation of an ordered surface alloy. AB - Scanning tunnelling microscopy (STM), low energy ion scattering spectroscopy (LEIS), X-ray photoelectron spectroscopy (XPS) and high resolution electron energy loss spectroscopy (HREELS) were applied for studying Au deposited on the Rh(111) surface. Both the deposition of Au at different substrate temperatures (400-800 K) and the effect of annealing Au deposited at 500 K were investigated. Gold deposition at 500 K, investigated by STM and LEIS methods, revealed that up to half monolayer Au the system exhibits clearly layer-by layer growth; however, above this coverage a slight deviation was identified, mainly due to kinetic and morphological effects. A continuous cover layer of Au was formed only above ~2.5 monolayers (ML). Below this coverage, the pseudomorphic character of the Au overlayer was clearly proven by STM, but this feature disappears at 4 ML coverage. A moderate (5-10%) surface mixing of the two metals was observed only above 600 K, for both annealing the Au layer formed at lower temperatures and performing the deposition at elevated temperatures. Above 600 K a clear step-flow growth mechanism was verified. Depending on the Au coverage, a more extended mixing of the top layer and the sublayer was observed at even higher temperatures. In this case, nano-range ordering of the alloyed layer was detected by STM, where the lateral extension of the uniform commensurate (2 * 1) domains was around 4 * 4 nm2. In this case, the local intralayer mixing of Rh and Au can locally reach a value of 50%. The proposed structural model for the (2 * 1) alloy phase was also corroborated by HREELS investigations on CO adsorption.

PMID- 27711371 TI - Sulfur ion concentration dependent morphological evolution of CdS thin films and its subsequent effect on photo-electrochemical performance. AB - The sulfur ion concentration dependent morphological evolution and its subsequent effect on photo-electrochemical properties of chemically synthesized CdS thin films have been systematically investigated. The plausible growth mechanism for the morphological evolution of CdS thin films due to a change in sulfur ion concentration has been proposed. Scanning electron micrographs (SEMs) reveal that the morphology of CdS thin films has been changed from spherical grains to vertically aligned nanoflakes by systematic control of sulfur ion concentration. This article elucidates the astute relationships between precursor concentrations, reaction rate and morphological evolution. The X-ray diffraction (XRD) patterns reveal the formation of hexagonal wurtzite CdS thin films with the preferred (002) orientation for CdS nanoflakes, which is further supported by the analysis of the high resolution transmission electron micrographs (HRTEMs). Optical absorption studies show a red shift in the absorption edge with an increase in sulfur concentration. The beneficial role of nanoflake formation is easily reflected in the photo-electrochemical performance. Improved solar cell performances are observed for CdS nanoflakes grown with a sulfur to cadmium ion concentration ratio of 4 (S : Cd = 4).

AB - We show that the proportion of double Auger decay following creation of single 1s core holes in molecules containing C, N and O atoms is greater than usually assumed, amounting to about 10% of single Auger decay in many cases. It varies from molecule to molecule, where the size of the molecule has a positive correlation to the amount of double Auger decay. In neon, examined as a related benchmark, the proportion of double Auger decay is similar to that in methane, and is in the order of 5%.

AB - Peptide hydrolysis has been involved in a wide range of biological, biotechnological, and industrial applications. In this perspective, the mechanisms of three distinct peptide bond cleaving enzymes, beta secretase (BACE1), insulin degrading enzyme (IDE), and bovine lens leucine aminopeptidase (BILAP), have been discussed. BACE1 is a catalytic Asp dyad [Asp, Asp-] containing aspartyl protease, while IDE and BILAP are mononuclear [Zn(His, His, Glu)] and binuclear [Zn1(Asp, Glu, Asp)-Zn2(Lys, Glu, Asp, Asp)] core possessing metallopeptidases, respectively. Specifically, enzyme-substrate interactions and the roles of metal ion(s), the ligand environment, second coordination shell residues, and the protein environment in the functioning of these enzymes have been elucidated. This information will be useful to design small inhibitors, activators, and synthetic analogues of these enzymes for biomedical, biotechnological, and industrial applications.

AB - Two hexanuclear metalloprisms possessing three dibenzo[24]crown-8 units were generated in quantitative yields by complexation of the predesigned tetratopic 2,2':6',2''-terpyridine ligand (T) with CdII and ZnII ions, respectively. The prismatic hosts were subsequently self-assembled with the trifunctional guest molecule (TriG) containing dibenzylammonium ions to afford the corresponding metallo-supramolecular pseudo-suit[3]anes. It was serendipitously found that the host-guest inclusion rates could be modulated by the subtle dynamic difference in metal-ligand frameworks, finally leading to a selective encapsulation event in the presence of both metallo-suits.

AB - We report the synthesis and characterization of a pH-sensitive fluorescence switch based on a conformationally-locked green fluorescent protein (GFP) chromophore. The chromophore differs from difluoroboryl-locked parent by the addition of a titratable alcohol group on the imidazolinone ring. The chromophore is fluorescent at pH <= 5, but becomes non-fluorescent at higher pH, where the substituent is ionized. We use a quantum chemical model to show that the mechanism of the fluorescence turn-off is electronically analogous to photochemical meta effects in aryl-containing systems. PMID- 27711377 TI - Encapsulation capacity and natural payload delivery of an anticancer drug from boron nitride nanotube. AB - The behavior of confined anticancer carboplatin (CPT) molecules in a single (10, 10) boron nitride nanotube (BNNT) was studied by means of molecular dynamics simulations. Our study revealed a very large storage capacity of BNNT. Analysis of the energy profiles depending on the number of confined molecules, and on their spatial organization allowed us to quantify the ability of BNNT to vectorize CPT. Indeed, BNNT despite its small radius presented a large inner volume that favored stable encapsulation of multiple active anticancer molecules. Moreover, in our molecular dynamics simulations, the empty BNNT and the BNNT filled with CPT diffused spontaneously to the cell membrane and were able to passively enter inside lipid bilayers by a lipid-assisted mechanism. This property has been used to deliver naturally anticancer drugs to cellular targets. Using this enhanced drug delivery system, we have provided a definitive solution to the problem of drug release and have thus opened up a new way of targeting cancer cells. Indeed, regardless of the mode of action of the platinum complex towards the cell, the delivery of the drug on site should limit the side effects of the drug.

The new conjugates were radiolabeled with zirconium-89 to give complexes that are more resistant to ligand exchange when compared to currently used H3DFO derivatives and result in high quality positron emission tomography images in mouse models of HER2 positive breast cancer. PMID- 27711379 TI - Improving the photocatalytic activity of s-triazine based graphitic carbon nitride through metal decoration: an ab initio investigation. AB - Graphitic carbon nitride based semiconductor materials are found to be potential photocatalysts for generating hydrogen through solar water splitting. Through more accurate hybrid density functional theory calculations, we attempted to tune the electronic band structure of poly s-triazine based graphitic carbon nitride by decorating it with different metal atoms and clusters for improving its visible light absorption efficiency. For deposition on the two-dimensional carbon nitride surface, a range of metals have been considered which include all the 3d transition metals and the noble metals (Ag, Au, Pt and Pd). Our study reveals that though the band gaps of all the metal decorated systems were less than that of pristine carbon nitride, in most of the cases, metal decoration leads to the formation of mid gap impurity states, which can hinder the mobility of charge carriers. However, in the case of Ag and its four atom cluster deposited systems, no mid gap states were observed. In all the metal decorated systems, the measured band edge potentials were also found to satisfy the thermodynamic criterion for overall water splitting. The calculated optical absorption spectra show a shift in the absorption band towards the visible region upon metal decoration. Our results indicate that among all the considered metal atoms silver is the preferred candidate for deposition on the carbon nitride surface for improved photocatalytic activity.

PMID- 27711383 TI - Probing ligand-induced modulation of metallic states in small gold nanoparticles using conduction electron spin resonance. AB - Thiolate-protected gold nanoparticles have a rich history as model systems for understanding the physical and chemical properties of metallic nanoscale materials that, in turn, form the basis for applications in areas such as molecular electronics, photocatalytic systems, and plasmonic solar cells. It is well known that the electronic properties of gold nanoparticles can be tuned by modifying the geometry, size and dielectric surrounding of the particle. However, much less is known of how modifications to the surface chemistry modulates the electronic properties of gold nanoparticles. In part, this stems from the fact that there are few good tools for measuring the electronic properties with the sensitivity required for following the response to subtle changes in surface chemistry. In this work, we demonstrate conduction spin electron resonance (CESR) to be a sensitive and selective probe to determine how changes in surface chemistry of gold nanoparticles affect the metallic states near the Fermi energy. Using a series of para-substituted aromatic thiolate ligands, we find that the g factor, as measured using CESR, correlates well with experimental and computational parameters often used to understand ligand effects in classical inorganic complexes. This suggests classical inorganic reasoning can function as a framework for understanding how to control the electronic properties of gold nanoparticles using their surface chemistry.

PMID- 27711385 TI - Theoretical prediction of long-range ferromagnetism in transition-metal atom doped d0 dichalcogenide single layers SnS2 and ZrS2. AB - We have systematically investigated the effects of transition-metal (TM) atom (Sc Zn) doping in 2D d0 materials SnS2 and ZrS2via the density functional theory method. Our results demonstrate that the conductivity and magnetism of SnS2 and ZrS2 can be engineered to spin-polarize half-metal/metal with appropriate TM dopants. For both materials, nontrivial magnetic interactions can be induced by V/Cr/Mn/Fe/Co doping. Specifically, the various behaviors of the magnetic exchanges in TM-doped SnS2 and ZrS2 are due to the competition between the super exchange, the double exchange, and the p-d exchange interactions, which are dependent on the dopants' chemistry and spatial positions. Thus, our results give potential guidance for future experiments to create functionalized d0 nano electronic devices. PMID- 27711386 TI - Modelling the local atomic structure of molybdenum in nuclear waste glasses with ab initio molecular dynamics simulations. AB - The nature of chemical bonding of molybdenum in high level nuclear waste glasses has been elucidated by ab initio molecular dynamics simulations. Two compositions, (SiO2)57.5-(B2O3)10-(Na2O)15-(CaO)15-(MoO3)2.5 and (SiO2)57.3 (B2O3)20-(Na2O)6.8-(Li2O)13.4-(MoO3)2.5, were considered in order to investigate the effect of ionic and covalent components on the glass structure and the formation of the crystallisation precursors (Na2MoO4 and CaMoO4). The coordination environments of Mo cations and the corresponding bond lengths calculated from our model are in excellent agreement with experimental observations. The analysis of the first coordination shell reveals two different types of molybdenum host matrix bonds in the lithium sodium borosilicate glass. Based on the structural data and the bond valence model, we demonstrate that the Mo cation can be found in a redox state and the molybdate tetrahedron can be connected with the borosilicate network in a way that inhibits the formation of crystalline molybdates. These results significantly extend our understanding of bonding in Mo-containing nuclear waste glasses and demonstrate that tailoring the glass composition to specific heavy metal constituents can facilitate incorporation of heavy metals at high concentrations. PMID- 27711392 TI - Strong Fermi level pinning induces a high rectification ratio and negative differential resistance in hydrogen bonding bridged single cytidine pair junctions. AB - We propose a high performance single molecule rectifier by sandwiching a deoxycytidine base pair between gold electrodes. The conductance of the single base pair junction can be controlled by its protonation status, with ON/OFF ratios between the protonated (pCC) and deprotonated (CC) junctions of 3-5 orders of magnitude. In the conducting pCC state, we observed a high rectification ratio of two orders of magnitude at bias voltage values around 0.1 V. This rectification ratio surpasses most of the theoretical designs for single molecular rectifiers, while the low working voltage implies significant energy efficiency. Negative differential resistance (NDR) was also witnessed in the protonated state, with a peak to valley ratio of 24. Both the rectifying and NDR effects originate from strong Fermi level pinning effects. The electronic performance offers these single base pair junctions potential applications as a unimolecular rectifier or switch with an NDR effect. The current-voltage response is unique compared with those of the reported canonical A-T and G-C pairs, and provides the possibility to be used for i-motif DNA structure recognition or sequencing.

AB - As molecular machines move to exciting applications in various environments, the study of medium effects becomes increasingly relevant. It is difficult to predict how, for example, the large apolar structure of a light-driven rotary molecular motor is affected by a biological setting or surface proximity, while for future nanotechnology precise fine tuning and full understanding of the isomerization process are of the utmost importance. Previous investigations into solvent effects have mainly focused on the relatively large solvent-solute interaction of hydrogen bonding or polarization induced by the isomerization process. We present a detailed study of a key step in the rotary process i.e. the thermal helix inversion of a completely apolar rotary molecular motor in 50 different solvents and solvent mixtures. Due to the relative inertness of this probe, we are able to study the influence of subtle solvent-solvent interactions upon the rate of rotation. Statistical analysis reveals which solvent parameters govern the isomerization process.

AB - For decades, akuammiline alkaloids have attracted synthetic chemists due to their intriguing molecular architecture. Among the different structural elements embedded in their carboskeleton, the methanoquinolizidine system constitutes the signature structural element of this alkaloid family. Herein, we describe a novel synthetic access to this system which relies on a [2,3]-Stevens rearrangement and results in the formal synthesis of strictamine. PMID- 27711395 TI - A non-dissociative open-flask hydroboration with ammonia borane: ready synthesis of ammonia-trialkylboranes and aminodialkylboranes. AB - Under open-flask conditions, ammonia borane hydroborates olefins in refluxing tetrahydrofuran. Unlike conventional hydroboration, the Lewis base (ammonia) is not dissociated from the boron center. Terminal alkenes selectively provide ammonia-trialkylborane complexes. On the other hand, internal alkenes afford aminodialkylboranes via a metal-free hydroboration-dehydrogenation sequence. Alkaline hydrogen peroxide oxidation of the products provides the corresponding alcohols in high yields. PMID- 27711396 TI - Elastic coupling between spin-crossover particles and cellulose fibers. AB - Composite materials made of cellulose fibers and spin crossover micro-particles were investigated by magnetic measurements and dynamic mechanical analysis (DMA). The storage modulus of the cellulose handsheet (0.6 GPa at room T) is significantly enhanced in the composite (1.7 GPa). The latter also displays a reversible increase of ca. 10% when switching the magnetic spin state of the particles from the low spin (LS) to the high spin (HS) form. Around the spin transition temperature a loss modulus peak is also observed, highlighting the strong viscoelastic coupling between the particles and the cellulose matrix. These results pave the way for the development of a novel family of actuator materials based on spin crossover-polymer composites.

AB - Herein, we report the intriguing structure, optical absorption and electrochemical properties of the transition-sized Au92(TBBT)44 (Au92 for short, TBBT = 4-tert-butylbenzenethiolate) nanoparticle. An interesting observation is the 4H phase array of Au92 nanoparticles in the unit cells of single crystals. PMID- 27711399 TI - New insights into the photoswitching mechanisms of normal dithienylethenes. AB - The photoswitching and competitive processes of the referent photochromic diarylethene derivative 1,2-bis(2,4-dimethyl-5-phenyl-3 thienyl)perfluorocyclopentene (DTE) and a novel bridged analog DTE-m5 have been investigated by state-of-the-art TD-DFT calculations and ultrafast spectroscopy supported by advanced chemometric data treatments. Focusing on DTE, the overall deactivation pathway of both antiparallel (AP) and parallel (P) conformers of the open form (OF) (1 : 1 in solution) has been resolved and rationalized starting from the Franck-Condon (FC) region to the ground state recovery. For the photo excited P conformer, after ultrafast relaxation (~200 fs) towards the S1 relaxed state, an expected ISC occurred (55 ps) to produce a triplet state, 3P, the latter relaxing within 2.5 MUs. Concerning the AP conformer, the photocyclization reaction is reported to proceed immediately (100 fs) starting from the FC region while the relaxed singlet state is populated in parallel. For the first time, we discovered that the latter state evolves through an unexpected ISC process (1 ps) giving rise to a second triplet state,3AP. For DTE-m5, by slightly constraining the molecule with the bridge, this triplet becomes reactive and participates in the formation of 10% of closed form (CF) probably through an adiabatic mechanism. Concerning the photoreversion, in accordance with the literature, we report on a two-step process, a 190 fs vibrational relaxation followed by a 6 ps ring-opening reaction. For the overall species at the singlet or triplet manifold, the use of advanced MCR-ALS allows us to obtain specific spectral signatures. This study is therefore a new step within the comprehension of DTE photochemistry. PMID- 27711398 TI - Long-lived states to sustain SABRE hyperpolarised magnetisation. AB - The applicability of the magnetic resonance (MR) technique in the liquid phase is limited by poor sensitivity and short nuclear spin coherence times which are insufficient for many potential applications. Here we illustrate how it is possible to address both of these issues simultaneously by harnessing long-lived hyperpolarised spin states that are formed by adapting the Signal Amplification by Reversible Exchange (SABRE) technique. We achieve more than 4% net 1H polarisation in a long-lived form that remains detectable for over ninety seconds by reference to proton pairs in the biologically important molecule nicotinamide and a pyrazine derivative whose in vivo imaging will offer a new route to probe disease in the future. PMID- 27711400 TI - Understanding of the formation of shallow level defects from the intrinsic defects of lead tri-halide perovskites. AB - Organic-inorganic hybrid perovskites have unique electronic properties in which deep level defects are rarely formed. This unique defect characteristic is the source of the long carrier diffusion length. This theoretical study shows what causes this characteristic formation of shallow level defects in lead tri-halide perovskites. Comparative studies between iodides and other halides showed that deep level defect states were generated for Cl based perovskites. Longer Pb halide bond lengths and narrower band gaps are beneficial for preventing deep level defect states. Additionally, our study shows that the formation of shallow level defects does not change even when the lattice structures of the perovskites do not reach their equilibrium structures. PMID- 27711402 TI - Photodissociation dynamics of dinitrite at 355 nm: initiation of a reactive pathway. AB - Dinitrites are effective nitrosating reagents in preparative chemistry and their decomposition products are involved in the atmospheric reaction of volatile organic compounds with nitrogen oxides (NOx). In this work, photodissociation dynamics of five alkyl dinitrites were investigated by detecting the LIF spectra of the dissociation products and theoretical calculations. The results showed that the C-C bond connecting the two nitrosooxy (-ONO) functional groups was the weakest bond in vicinal dinitrites and aldehydes were the dissociation products. For dinitrites with two ONO groups separated by a CH2 group, vinoxy and 1 methylvinoxy radicals were detected as the fragments via photodissociation, indicating a different mechanism compared to thermal decomposition. This observation demonstrated that a new reactive pathway could be initiated by photolysis of dinitrites. PMID- 27711401 TI - Tandem neopentyl glycol maltosides (TNMs) for membrane protein stabilisation. AB - A novel class of detergents, designated tandem neopentyl glycol maltosides (TNMs), were evaluated with four target membrane proteins. The best detergent varied depending on the target, but TNM-C12L and TNM-C11S were notable for their ability to confer increased membrane protein stability compared to DDM. These agents have potential for use in membrane protein research. PMID- 27711403 TI - Removal of alkali and transition metal ions from water with hydrophobic deep eutectic solvents. AB - Hydrophobic deep eutectic solvents were used for the first time for the removal of metal ions from non-buffered water. It was shown that the extraction occurs via an ion exchange mechanism in which all transition metal ions could be extracted with high distribution coefficients, even for high Co2+ concentrations and low DES/water mass ratios. Maximum extraction efficiency could be reached within 5 s and regeneration was possible. PMID- 27711404 TI - Benzoannelated aza-, oxa- and azaoxa[8]circulenes as promising blue organic emitters. AB - In the present work, we studied the synergetic effect of benzoannelation and NH/O substitution for enhancing the absorption intensity in a series of novel designed benzoannelated aza- and oxa[8]circulenes. Semi-empirical estimations of the fluorescence rate constants allowed us to determine the most promising fluorophores among all the possible benzoannelated aza-, oxa- and mixed azaoza[8]circulenes. Among them, para-dibenzoannelated [8]circulenes demonstrated the most intense light absorption and emission due to the prevailing role of the linear acene chromophore. Calculated phifl values are in complete agreement with experimental data for a number of already synthesized circulenes. Thus, we believe that the most promising circulenes designed in this study can demonstrate an intensive fluorescence in the case of their successful synthesis, which in turn could be extremely useful for the fabrication of future blue OLEDs. Special attention is devoted to the aromaticity features and peculiarities of the absorption spectra for the two highly-symmetrical (D4h ground state symmetry) pi isoelectronic species as well as the so-called tetrabenzotetraaza[8]circulene and tetrabenzotetraoxa[8]circulene molecules. Both of them are characterized by rich electronic spectra, which can be assigned only by taking into account the vibronic coarse structure of the first electronic absorption band; the 0-1 and 0 2 transitions were found to be active in the absorption spectrum in complete agreement with experimental data obtained for both energy and intensity. The corresponding promotive vibrational modes have been determined and their vibronic activity estimated using the Franck-Condon approximation. PMID- 27711405 TI - Influence of electric potential on the apparent viscosity of an ionic liquid: facts and artifacts. AB - According to recent findings, the steady shear viscosity of the ionic liquid 1 ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([Emim][Tf2N]) decreases significantly under the influence of electric potential. This implies a causal connection between nanoscale ordering at the electrified interface and a macroscopic change of transport properties. To study this phenomenon in more detail, we reproduced the above-mentioned measurements; however, we find no evidence that the viscosity of [Emim][Tf2N] is a function of electric potential. Additionally, our results show that steady shear measurements can lead to artifacts that, at first glance, may appear to be potential-induced changes in viscosity. We demonstrate that the artifacts result from a sliding electrical contact at the working electrode of the electrochemical cell and we suggest to consider our findings for future viscosity measurements of ionic liquids. PMID- 27711406 TI - The flow patterning capability of localized natural convection. AB - Controlling flow patterns to align materials can have various applications in optics, electronics, and biosciences. In this study, we developed a natural convection-based method to create desirable spatial flow patterns by controlling the locations of heat sources. Fluid motion in natural convection is induced by the spatial fluid density gradient that is caused by the established spatial temperature gradient. To analyze the patterning resolution capability of this method, we used a mathematical model combined with nondimensionalization to correlate the flow patterning resolution with experimental operating conditions. The nondimensionalized model suggests that the flow pattern and resolution is only influenced by two dimensionless parameters, and , where Gr is the Grashof number, representing the ratio of buoyancy to the viscous force acting on a fluid, and Pr is the Prandtl number, representing the ratio of momentum diffusivity to thermal diffusivity. We used the model to examine all of the flow behaviors in a wide range of the two dimensionless parameter group and proposed a flow pattern state diagram which suggests a suitable range of operating conditions for flow patterning. In addition, we developed a heating wire with an angular configuration, which enabled us to efficiently examine the pattern resolution capability numerically and experimentally. Consistent resolutions were obtained between the experimental results and model predictions, suggesting that the state diagram and the identified operating range can be used for further application. PMID- 27711407 TI - Initial dissolution of D2O at the gas-liquid interface of the ionic liquid [C4min][NTf2] associated with hydrogen-bond network formation. AB - We have studied the initial dissolution of D2O at the interfacial surface of the flowing jet sheet beam of the ionic liquid (IL) [C4min][NTf2] using the King and Wells method as a function of both the temperature and collision energy of the IL. The initial dissolution probability of D2O into the IL [C4min][NTf2] was found to follow the general propensity that the solubility of gases into a liquid decreases with temperature. However, a large partial molar enthalpy and entropy for the initial dissolution of D2O in the IL [C4min][NTf2] were observed from the temperature dependence of the initial dissolution probability: DeltaHl = -53 +/- 8 kJ mol-1, DeltaSl = -210 +/- 30 J mol-1 K-1. In addition, it was found that the collision energy significantly reduced the initial dissolution probability. We propose that the associated D2O molecules at the interface of the IL [C4min][NTf2] make a hydrogen-bond network around the [NTf2]- anion before dissolution into the deeper portion of the interface layer. PMID- 27711408 TI - Complexes of Ni(ii) and Cu(ii) with small peptides: deciding whether to deprotonate. AB - The observed variety of metal-ion complexation sites offered by peptides reflects a basic tension between charge solvation of the ion by Lewis-basic chelating groups versus amide nitrogen deprotonation and formation of metal-nitrogen bonds. Gas-phase models of metal-ion coordination can illuminate the factors governing this choice in condensed-phase proteins and enzymes. Here, structures of gas phase complexes of Ni(ii) and Cu(ii) with tri- and tetra-peptide ligands are mapped out using a combination of Infrared Multiple Photon Dissociation (IRMPD) spectroscopy and density functional theory (DFT) computations. The two binding modes give distinctive IRMPD signatures, particularly in the diagnostic region 1500-1550 cm-1. Previous observations have suggested that Ni(ii) complexes preferentially show the iminol rearrangement pattern (Im) giving low-spin square planar geometries with metal-ion bonds to deprotonated amide nitrogens. In contrast, alkaline earth metal ion complexes prefer amide carbonyl oxygens chelating the metal ion with pyramidal geometry (charge-solvation, CS). Surprisingly, it is shown here that the Gly4 complexes are CS bound, in contrast with the expectation of Im binding. It is suggested that CS binding is actually a normal Ni(ii) and Cu(ii) binding mode to simple peptides lacking participating side chains. Three factors are suggested to influence the choice between CS and Im binding patterns: (1) presence of an accessible side-chain Lewis-basic proton interaction site (FGGF, FGG and HAA complexes); (2) short chain length of the peptide leading to a shortage of accessible carbonyl oxygen sites for CS binding, (AAA, FGG and HAA complexes); (3) outright deprotonation of the ligand giving net negatively charged Im[Ni2+(Gly4-3H+)]- and Im[Ni2+(Ala3-3H+)]- complexes, which have a triply-deprotonated ligand. IRMPD spectra of [Cu2+Gly4]2+ and [Cu2+(Gly4 3H+)]- complexes suggest that their structures are similar to their Ni2+ analogs. PMID- 27711409 TI - First-principles assessment of CO2 capture mechanisms in aqueous piperazine solution. AB - Piperazine (PZ) and its blends have emerged as attractive solvents for CO2 capture, but the underlying reaction mechanisms still remain uncertain. Our study particularly focuses on assessing the relative roles of PZCOO- and PZH+ produced from the PZ + CO2 reaction. PZCOO- is found to directly react with CO2 forming COO-PZCOO-, whereas PZH+ will not. However, COO-PZCOO- appears very unlikely to be produced in thermodynamic equilibrium with monocarbamates, suggesting that its existence would predominantly originate from the surface reaction that likely occurs. We also find production of H+PZCOO- to be more probable with increasing CO2 loading, due partly to the thermodynamic favorability of the PZH+ + PZCOO- -> H+PZCOO- + PZ reaction; the facile PZ liberation may contribute to its relatively high CO2 absorption rate. This study highlights an accurate description of surface reaction and the solvent composition effect is critical in thermodynamic and kinetic models for predicting the CO2 capture processes. PMID- 27711410 TI - C96H30 tailored single-layer and single-crystalline graphene quantum dots. AB - By controllable synthesis of a carbon precursor and with a suitable preparation routine, a series of single-layer and single-crystalline graphene quantum dots (GQDs) with uniform size distribution were prepared from C96H30. It was found that the absorption, photoluminescence (PL) and two-photon photoluminescence (TPPL) show a high size-dependent effect with a redshift that occurs as the size grows. Two-photon absorption (TPA) properties of GQDs were measured at 800 nm under a femtosecond pulse laser. Two-photon bioimaging of HeLa cells was carried out to determine TPA properties. Most significantly, the as-prepared GQDs showed potential in a practical application in two-photon cell bioimaging due to their high contrast TPPL. In addition, the superior nonlinear absorption, stable TPPL and excellent solubility were beneficial to the optical limiting (OL) properties. PMID- 27711411 TI - N2 activation on Al metal clusters: catalyzing role of BN-doped graphene support. AB - The successful sustenance of life demands an ambient abiotic process for N2 activation and dissociation. The Bosch-Haber process remains the only abiotic and synthetic means for N2 activation and its fixation. Metal nanoclusters have been recently reported for activating molecular nitrogen. Interestingly, the metal clusters explored so far for N2 activation are free clusters and, hence, are practically not applicable by experimental chemists. Using density functional theory (DFT) based methodology, we propose a potential catalytic system for di nitrogen activation, viz. supported Al clusters. Al clusters supported on BN doped graphene sheets are seen to activate N2 molecule with a red shift in the N N stretching frequency up to 874 cm-1 with activation barriers as low as 1.14 eV. PMID- 27711412 TI - Theoretical study of the binding profile of an allosteric modulator NS-1738 with a chimera structure of the alpha7 nicotinic acetylcholine receptor. AB - Potentiation of the function of the alpha7 nicotinic acetylcholine receptor (alpha7-nAChR) is believed to provide a possible way for the treatment of cholinergic system dysfunctions such as Alzheimer's disease and schizophrenia. Positive allosteric modulators (PAMs) are able to augment the peak current response of the endogenous agonist of alpha7-nAChR by binding to some allosteric sites. In this study, the binding profile of a potent type I PAM, NS-1738, with a chimera structure (termed alpha7-AChBP) constructed from the extracellular domain of alpha7-nAChR and an acetylcholine binding protein was investigated with molecular docking, molecular dynamics simulation, and free energy calculation methods. We found that NS-1738 could bind to three allosteric sites of alpha7 AChBP, namely, the top pocket, the vestibule pocket and the agonist sub-pocket. NS-1738 has moderate binding affinities (-6.76 to -9.15 kcal mol-1) at each allosteric site. The urea group is critical for binding and can form hydrogen bond interactions with the protein. The bulky trifluoromethyl group also has a great impact on the binding modes and binding affinities. We believe that our study provides valuable insight into the binding profiles of type I PAMs with alpha7-nAChR and is helpful for the development of novel PAMs. PMID- 27711413 TI - Solvent effects on de-excitation channels in the p-coumaric acid methyl ester anion, an analogue of the photoactive yellow protein (PYP) chromophore. AB - In an attempt to shed light on the environmental effects on the deactivation channels of the PYP chromophore, radiative and non-radiative deactivation mechanisms of the anionic p-coumaric acid methyl ester (pCE-) in the gas phase and water solution are compared at the CASPT2//CASSCF/cc-pVDZ level and, when necessary, at the CASPT2//CASPT2/cc-pVDZ level. We find that the solvent produces dramatic modifications on the free energy profile of the S1 state. Two twisted structures that are minima in the gas phase could not be localized in aqueous solution. Furthermore, the relative stability of minima and conical intersections (CIs) is reverted with respect to the gas phase values, affecting the prevalent de-excitation paths. As a consequence of these changes, three competitive de excitation channels are open in aqueous solution: the fluorescence emission from a planar minimum on S1, the trans-cis photoisomerization through a CI that involves the rotation of the vinyl double bond and the non-radiative, non reactive, de-excitation through the CI associated with the rotation of the single bond adjacent to the phenyl group. In the gas phase, the minima are the structures with lower energy, while in solution the CIbeta structure, characterized by a large charge separation, is strongly stabilized by interactions with water molecules and becomes the structure with the lowest energy on S1. These facts explain the low fluorescence signal of pCE- in aqueous solution and the presence of partial trans-cis photoisomerization in this system. PMID- 27711414 TI - Smart adsorbents with reversible photo-regulated molecular switches for selective adsorption and efficient regeneration. AB - Traditional adsorbents with fixed pore surface properties are unlikely to achieve both selective adsorption and efficient desorption, which are extremely desirable in adsorption processes. Here we report a new class of smart adsorbents by introducing photo-responsive azobenzene derivatives to pore interiors of mesoporous silica. The azobenzene molecules are applied as ON-OFF switches for active sites, and are reversibly regulated by UV/visible light irradiation, thus endowing the adsorbents with unprecedented properties to achieve selective adsorption and efficient desorption. PMID- 27711415 TI - Sorption of 3-hydroxyflavone within channel type zeolites: the effect of confinement on copper(ii) complexation. AB - The confinement effect on the complexation process of Cu(ii) by 3-hydroxyflavone (3HF) was investigated by studying 3HF incorporation in channel-type copper containing ZSM-5 and mordenite (MOR) zeolites characterized by different pore diameters. Complementary electronic and vibrational spectroscopy techniques point out two distinct behaviors upon 3HF sorption and subsequent complexation depending on the channel diameter in CuZSM-5 and CuMOR. To determine the influence of the internal environment on the interaction between the copper cation and the guest molecule, and to predict the structure of the complexes formed within the narrow-pore ZSM-5 and in the larger pore mordenite, the vibrational spectra of the complexes were calculated using quantum chemical calculations at the DFT level. From the calculations, it is derived that the Cu(3HF)+ chelate is formed in CuMOR indicating a weak interaction with the pore walls. In contrast, due to high confinement in CuZSM-5, interactions between copper cations and the narrower pore walls are assumed to take place in addition to 3HF metal complexation. To emphasize the fact that zeolites act as a solid solvent, 3HF complexation was also investigated in methanol solution. In such liquid media, a stable complex Cu(3HF)2 of 1 : 2 stoichiometry resulting in a double chelation with the metal cation was found to coexist with a minor species [Cu(3HF)(MeOH)2]+ of 1 : 1 stoichiometry. These two complexes show striking analogy with those observed in CuZSM-5 and CuMOR, respectively. Thus, it appears clearly that zeolites can constitute an ideal tool to control and orientate molecular reactivity for the guest in the isolated state.

AB - The active sites of hydrogenases have inspired the design of molecular catalysts for hydrogen evolution and oxidation. In this feature article, we showcase key elements of bio-inspiration before embarking on a tour of a representative series of molecular hydrogen evolving catalysts (HECs) and describing the toolbox available for benchmarking their performances. We then show how such catalysts can be immobilized on conducting substrates to prepare electrode materials active for hydrogen evolution and oxidation with a special emphasis on cobalt diimine dioxime complexes and DuBois' nickel diphosphine compounds. We finally discuss the optimization required for implementing molecular-engineered materials into operational devices and illustrate how such molecular approaches can be expanded to other fuel-forming processes such as the electrochemical valorisation of carbon dioxide and the oxygen reduction or water oxidation reactions.

PMID- 27711418 TI - From intermolecular interactions to structures and properties of a novel cocrystal explosive: a first-principles study. AB - By employing a first-principles method, we conducted a thorough study on a novel cocrystal explosive 1 : 1 NTO : TZTN and gained insight into the interaction structure-property interrelationship. Mulliken bond orders, Hirshfeld surfaces, intermolecular binding energies, packing coefficients, and oxygen balance were calculated to analyze the intermolecular interactions and structures of the cocrystal explosive. The cocrystallization of NTO and TZTN molecules enhances the intermolecular binding force, which drives the synthesis of the cocrystal. However, the cocrystallization decreases the molecular packing density along the closest packed directions, which reduces the density by 10.5% and deteriorates the oxygen balance. All of these lead to a reduction in the detonation performance compared to NTO explosives. We have also proposed a new method to evaluate the impact sensitivity according to the lattice dynamics calculation. The cocrystal explosive has a lower impact sensitivity than TZTN but higher than NTO, which agrees well with experiments.

PMID- 27711421 TI - Local, solvation pressures and conformational changes in ethylenediamine aqueous solutions probed using Raman spectroscopy. AB - Raman spectra of 1,2-ethylenediamine (EDA) in aqueous solutions are used to demonstrate that EDA molecules experience an anti-gauche conformational change resulting from the interactions with water. The observed Raman shift reveals a compressive (hydrophobic) effect of water on both methylene and amino groups of EDA. Raman spectra of EDA at high pressures are used as reference to quantify the intermolecular EDA-H2O interactions in terms of local pressures. These results are compared with macroscopic solvation pressures calculated from the cohesive energy parameter. We compare and discuss all our observations with available computational and experimental studies. PMID- 27711422 TI - Understanding the surface segregation behavior of transition metals on Ni(111): a first-principles study. AB - The surface composition of an alloying system has an important impact on its catalytic and chemical properties. The segregation behavior of 3d, 4d and 5d transition metals on an Ni(111) surface has been investigated by performing first principles calculations in the framework of density-functional theory with the generalized gradient approximation for the exchange-correlation functional. Our calculated surface segregation energies are in good agreement with the experimental data as well as with previous calculated results. Most importantly, we have made an attempt to correlate the surface segregation behavior with the surface energy difference between the alloying (solute) metal and the host metal, the elastic energy release, and the heat of solution of the alloying metal in the host metal. By doing so, we not only overcome the difficulties that empirical models encounter, but also clearly identify the importance of each contribution to the segregation behavior of an alloying metal. The present study provides valuable insight into the surface segregation behavior of solute atoms in alloying systems. PMID- 27711423 TI - Domain-dependent electronic structure and optical absorption property in hybrid organic-inorganic perovskite. AB - Hybrid organic-inorganic perovskites, represented by materials in the CH3NH3PbI3 series, have become one of the most promising materials for solar cells with a high power conversion efficiency and low cost. The ordered Pb-I cage in such hybrid perovskites can induce the polarized cations to form a variety of polarization domains with long-range order, which will lead to the formation of specific atomic conformations or metastable crystalline phases, unique electronic band structures and optical absorption properties. Such domain-dependent characteristics play a critical role in the phase transition and service stability of such solar cells, and also open up the opportunity of tuning their electronic structure. In the present study, we systematically investigate the band structures and optical absorption properties of different electronically ordered domains in CH3NH3PbI3. By comparing different perovskites containing various cations, we have clarified the important influence of cation polarization on domain-dependent properties. Our results provide not only a possible pathway for the manipulation of band structure by applying an external field, but also a novel scheme for improving the performance and stability of hybrid perovskites.

AB - The Birmingham Parallel Genetic Algorithm (BPGA) has been adopted for the global optimization of free and MgO(100)-supported Pd, Au and AuPd nanocluster structures, over the size range N = 4-10. Structures were evaluated directly using density functional theory, which has allowed the identification of Pd, Au and AuPd global minima. The energetics, structures, and tendency of segregation have been evaluated by different stability criteria such as binding energy, excess energy, second difference in energy, and adsorption energy. The ability of the approach in searching for putative global minimum has been assessed against a systematic homotop search method, which shows a high degree of success.

AB - The structure of the important technological glass Pyrex(r) was investigated by 1D- and 2D-correlation NMR techniques. Its local order was analysed in a first step by 1D 23Na, 27Al, 11B and 29Si MAS-NMR performed at 9.4 and 18.8 T. In a second step, its medium range order was documented using homo- and, for the first time, hetero-nuclear correlation NMR techniques: (i) the presence and the nature of BOB bonds were analysed using 2D 11B DQ-SQ map; (ii) the silicate speciation was probed using 2D 29Si/X (X = 11B, 23Na and 27Al) D-HMQC maps and (iii) the 27Al/11B interaction was studied using TRAPDOR-NMR experiments. Altogether, the set of NMR data was used to extract accurate NMR parameters, to rule out the presence of diborate and danburite superstructural units and to provide an updated structural model based on B3 based groups attached to a T4 network (T = Si, B, Al). PMID- 27711425 TI - Hydrogen evolution from water using Mo-oxide clusters in the gas phase: DFT modeling of a complete catalytic cycle using a Mo2O4-/Mo2O5- cluster couple. AB - Density functional theory (DFT) calculations using a small metal cluster couple, Mo2O4-/Mo2O5-, are used to model a complete catalytic cycle for H2 production from water. While Mo2O4- is known to readily react with water to form Mo2O5- and release H2, the principal challenge is in reducing Mo2O5- to Mo2O4- to complete the cycle. We investigate the role of several potential sacrificial reagents (ethylene, propylene, CO and acetylene) that can reduce Mo2O5- after the initial oxidation. DFT calculations of the free energy reaction pathways demonstrate the presence of overall kinetically accessible barriers that are below the entrance channel (separated reactants) in the Mo2O4- + H2O reaction (step I) followed by the Mo2O5- + sacrificial reagent reactions (step II). Though the overall reaction is thermodynamically favorable, the first step is highly exothermic while the second step is endothermic. The deepest part of the potential energy surface is a complex of Mo2O5- with the sacrificial reagent. If the energy gained in the first reaction and the succeeding complex formation is not lost due to collisions, the subsequent barriers can be overcome, leading to possible catalytic applications of the Mo2O4-/Mo2O5- cluster couple in H2 production reactions.

AB - Ligand H4LO(AP/AP) underwent ligand-centered C-O bond cleavage during a complexation reaction with Co(ii)-salt. The thus formed octahedral {CoII[(BQ-N Cat)]2}0 complex showed valence tautomerization in the solid state. While the process was triggered by the presence of lattice solvent, the nature of the solvent molecule has less effect on the process.

AB - The photocatalytic mechanism of a Cu2O/CuO hybrid system is disclosed in detail by density functional theory (DFT) calculations. The synergistic relationship of the two counterparts is confirmed by hydrogen peroxide (H2O2) formation on the CuO nanowires and dissociation on the Cu2O nanoparticles; this enables the system to self-sufficiently produce hydroxyl radicals, which is highly efficient in the photocatalytic degradation of methyl orange. The exposed surfaces are found to be crucial in the cooperative photocatalytic system, especially the Cu2O(111) surface, in the dissociation of H2O2. The distinct positions of the conduction band minimum and valence band maximum for CuO and Cu2O and synergic surface reactions enable the effective utilization of the electrons and holes generated by visible-light irradiation. Our results will contribute to a greater understanding of the specific mechanism of photodegradation catalyzed by Cu2O/CuO heterostructures, which may lead to promising directions in structure optimization for photocatalysts with high photocatalytic efficiency.

AB - In this work we utilize experimental and simulation techniques to examine the molecular level interaction of water with a MnO(1 * 1) thin film deposited onto Ag(100). The formation of MnO(1 * 1)/Ag(100) was characterized by low energy electron diffraction and scanning tunneling microscopy. Density functional theory (DFT) shows MnO(1 * 1) is thermodynamically more stable than MnO(2 * 1) by ~0.4 eV per MnO. Upon exposure to 2.5 Torr water vapor at room temperature, X-ray photoemission spectroscopy results show extensive surface hydroxylation attributed to reactivity at MnO(1 * 1) terrace sites. DFT calculations of a water monomer on MnO(1 * 1)/Ag(100) show the dissociated form is energetically more favorable than molecular adsorption, with a hydroxylation activation barrier 0.4 eV per H2O. These results are discussed and contrasted with previous studies of MgO/Ag(100) which show a stark difference in behavior for water dissociation.

AB - We have studied the melting process for crown-jewel structured Ir55, Ir54Au, Ir43Au12, Ir25Au30, Ir13Au42, and Au55 nanoclusters in the icosahedral, Ir55, Ir54Au, Ir43Au12, Ir19Au36, Ir13Au42, and Au55 nanoclusters in the cuboctahedral, and Ir54, Ir53Au, Ir47Au7, Ir17Au37, Ir7Au47, and Au54 nanoclusters in the decahedral morphologies. We have investigated the different thermodynamic, structural, and dynamical properties for the different nanoclusters in the different structures. Our thermodynamic results indicated that as the concentration of Au atoms in the nanoclusters increases, the absolute value of internal energy, and so the melting points, of the nanoclusters decrease. It is also shown that the Au atoms decrease the melting temperature of the pure cuboctahedral cluster more than that of the other structures. We have also found that the Au atoms were located in favorable positions at the surface sites of nanoalloys. Also, the doping of the Ir nanocluster by Au atoms makes the cluster more stable. It is also found that nanoclusters with different morphologies have almost the same stability. Our structural results indicated that after the melting process, the Au atoms generally tend to lie in the outer shell of the cluster, but the Ir atoms generally tend to lie in the core of the cluster (see the Ir13Au42 and Ir7Au47 nanoclusters, for example). We have also found the interesting result that the Ir7Au47 nanocluster shows a solid-solid transition from a decahedral structure to an icosahedral structure before melting. The Ir43Au12 nanocluster also shows a transformation from a cuboctahedral structure to an icosahedral-like structure before melting. Our dynamical results showed that doping of the Ir55 cluster with an Au atom sharply increases the self diffusion coefficient in the initial state in the solid phase, especially in icosahedral and cuboctahedral structures. It is also shown that the Ir13Au42 cluster in icosahedral and cuboctahedral and the Ir7Au47 and Ir17Au37 clusters in decahedral morphologies have smaller values of self-diffusion coefficients than other clusters after the melting point and that this could be due to the formation of core-shell structures.

AB - Although previous studies have indicated that the carbon nanotube (CNT) can be used for directed transportation of water and ions, it is still a challenging problem to design a CNT-based device for high performance water desalination. In this study, by using molecular dynamics simulations, we successfully design one type of CNT as a highly efficient desalination membrane through electrical resonance. By decorating the two ends of the CNT with vibrational charges, an alternating electric field is created inside the CNT. When the amplitude of the vibrational charge is 0.05 e, and the vibrational frequency is between 10 THz and 20 THz, the CNT can completely block the transportation of ions. The decrease of the amplitude or the deviation of the frequency in an appropriate range will gradually increase the ion flow. Besides, we also reveal the underlying molecular mechanism of ion blockage, i.e., the electric resonance can disrupt the water structure inside the CNT and then alter the hydration energy of ions inside the CNT. More importantly, we further demonstrate that this mechanism is universal, which is independent of the type of ions and the size of CNT. The present work could be useful for designing water desalination membranes with lower energy consumption and higher fresh water production.

PMID- 27711434 TI - The divide-and-conquer second-order proton propagator method based on nuclear orbital plus molecular orbital theory for the efficient computation of proton binding energies. AB - An efficient computational method to evaluate the binding energies of many protons in large systems was developed. Proton binding energy is calculated as a corrected nuclear orbital energy using the second-order proton propagator method, which is based on nuclear orbital plus molecular orbital theory. In the present scheme, the divide-and-conquer technique was applied to utilize local molecular orbitals. This use relies on the locality of electronic relaxation after deprotonation and the electron-nucleus correlation. Numerical assessment showed reduction in computational cost without the loss of accuracy. An initial application to model a protein resulted in reasonable binding energies that were in accordance with the electrostatic environment and solvent effects.

The obtained membrane 1 can be a platform to support Au nanoparticles (Au NPs) to generate an Au-MOF-polymer composite membrane Au@UiO-66-TEM (2). 1 and 2 can be used to build highly efficient continuous flow-through membrane reactors for Knoevenagel condensation of 4-nitrobenzaldehyde with malononitrile and 4-nitrophenol (4-NP) reduction at ambient temperature, respectively.

AB - The first palladium-catalyzed Sonogashira coupling of amides has been developed, which proceeds via a selective cleavage of the N-acylsaccharin C-N bond. Notably, the new approach employs N-acylsaccharins as coupling partners to give ynones in good to excellent yield.

PMID- 27711438 TI - Preparation and structure of Fe-containing aluminosilicate thin films. AB - In attempts to fabricate model systems of Fe-containing aluminosilicates, we studied the incorporation of iron into silicate and aluminosilicate bilayer films grown on Ru(0001). Structural characterization was performed by low energy electron diffraction, X-ray photoelectron spectroscopy, infrared reflection absorption spectroscopy and scanning tunneling microscopy. The experimental results show that even at low concentrations Fe does not randomly substitute Si(Al) cations in the silicate framework, but segregates into a pure silicate (aluminosilicate) phase and an Fe-silicate phase which is formed by an FeO(111) like layer underneath a silicate layer. At high Fe/(Si + Al) molar ratios, the resulting films showed two phases depending on the annealing temperature. In both phases, the surface exposes a silicate layer and the bottom layer is dominated by FeO. The Al ions seem to be present in the bottom layer at relatively low oxidation temperatures, but segregate as alumina clusters at the surface at higher temperatures. The results suggest that the formation of in-frame Fe species in silicalites and zeolites is thermodynamically unfavourable. This study provides further steps towards the rational design of model systems for studying surface chemistry of a wide class of layered minerals.

AB - Binding of Zn2+ to the coordinating supramolecular vesicle based on an aggregation induced emission amphiphile TPE-BPA immediately triggers the formation of charged vesicles. This induces vesicle fission and fluorescence reduction, suggesting a looser molecular packing in the charged vesicle membrane. Since cancer cells are highly charged, this indicates that the quick fission of cancer cells may have electrical charge origin.

AB - Synthetic glycopolypeptides are versatile glycopolymers used to conceive bioinspired nanoassemblies. In this work, novel amphiphilic glycopolypeptides were designed to incorporate lactose or galactan in order to prepare polymeric nanoassemblies with sizes below 50 nm. The bioactivity of the two different outer surface sugar units was evaluated by defining glycan relative binding affinities to human galectins 1 and 3. A specific multivalent effect was found only for polymeric nanoparticles displaying galactan with a significant increase of the binding activity as compared to free glycan in solution. Such synthetic designs present great potential as therapeutic tools to address galectin related pathologies.

AB - Bare alumina shows surprisingly high activity in non-oxidative dehydrogenation of isobutane to isobutylene. The activity is related to surface coordinatively unsaturated Al sites (Alcus), which are created upon removal of OH groups during alumina treatment at high temperatures. Alcus and neighbouring lattice oxygen represent the active site for isobutane dehydrogenation. PMID- 27711442 TI - Effects of atomic interaction stiffness on low-temperature relaxation of amorphous solids. AB - While low-temperature relaxations show significant differences among metallic glasses with different compositions, the underlying mechanism remains mysterious. Using molecular dynamics simulation, low-temperature relaxation of amorphous solids is investigated in model systems with different atomic interaction stiffness. It was found that as the interaction stiffness increases, the low temperature relaxation is enhanced. The fraction of mobile atoms increases with increasing interaction stiffness, while the length scale of dynamical heterogeneity does not change. The enhanced relaxation may be due to increased dynamical heterogeneity. These findings provide a physical picture for better understanding the origin of low-temperature relaxation dynamics in amorphous solids, and the experimentally observed different beta-relaxation behaviors in various metallic glasses. PMID- 27711443 TI - Acidity constants and redox potentials of uranyl ions in hydrothermal solutions. AB - We report a first principles molecular dynamics (FPMD) study of the structures, acidity constants (pKa) and redox potentials (E0) of uranyl (UO22+) from ambient conditions to 573 K. It is found that UO22+ keeps five coordination up to 573 K whereas UO2+ transforms from 5 to 4-coordinate as temperature increases to 573 K. The FPMD-based vertical energy gap method is used to derive pKas and E0s. The method is validated by comparing with available experimental data (for E0 under the ambient conditions and for pKas from ambient conditions to 367 K), with an uncertainty of 1-2 pKa units and 0.2 V for pKa and E0. The encouraging results demonstrate that the method may be used to predict the pH-Eh diagrams of f-block elements under the conditions of hydrothermal solutions. The results show that the acidity constants of uranyl decrease with temperature and are lower than 3.0 when the temperature is above 473 K, indicating that hydrolytic forms are dominant for U(vi) in the near neutral pH range. The reduction potential increases with temperature, indicating that the reduced state is more significant at higher temperatures. PMID- 27711444 TI - A multifunctional material of two-dimensional g-C4N3/graphene bilayer. AB - Using first-principles calculations, we present a multifunctional material of g C4N3/graphene bilayer with great potentials in the field of spintronics and photocatalysis. In g-C4N3/graphene bilayer, N atoms create localized spin polarization and p-doped graphene shows high charge carrier density, which makes this nanocomposite a perfect candidate for spintronic applications. Meanwhile, the charge redistribution occurred between the two layers also facilitates the separation of photogenerated electron-hole pairs. Moreover, the inclusion of C atoms into g-C3N4 closes the band gap of g-C3N4/graphene completely and induces more levels near the Fermi energy, and thus the g-C4N3/graphene bilayer displays enhanced visible light absorption compared to the g-C3N4/graphene bilayer. PMID- 27711446 TI - Experimental and computational studies of the roles of MgO and Zn in talc for the selective formation of 1,3-butadiene in the conversion of ethanol. AB - The one-step conversion of ethanol to 1,3-butadiene was performed using talc containing Zn (talc/Zn) as a catalyst. The influence of the MgO and Zn in the talc on the formation rate and selectivity for 1,3-butadiene were investigated. MgO as a catalyst afforded 1,3-butadiene with a selectivity that was nearly the same as talc/Zn at ~40% ethanol conversion at 673 K, although the rate of 1,3 butadiene formation over MgO was about 40 times lower than that over the talc/Zn. The introduced Zn cations were located in octahedral sites in place of Mg cations in the talc lattice. The Zn cations accelerated the rate of CH3CHO formation from ethanol, resulting in an increase in the rate of 1,3-butadiene formation. However, the rate of CH3CHO consumption to form crotonaldehyde was not influenced by Zn, although the distribution of crotonaldehyde was decreased with increasing Zn concentrations. X-ray photoelectron spectra of talc/Zn showed that the O1s binding energy was increased by increasing the concentration of Zn, while those of both Mg2p and Si2p were hardly influenced. DFT calculations were used to estimate the atomic charges on the O, Mg, Si, and Zn atoms when an atom of Zn per unit cell of talc was introduced into an octahedral site. On the basis of the results for the conversion of ethanol into 1,3-butadiene and the corresponding DFT calculations, the roles of the O, Zn, Mg, and Si atoms in the talc catalyst for the formation of 1,3-butadiene from ethanol were discussed. PMID- 27711447 TI - Pyrite surface environment drives molecular adsorption: cystine on pyrite(100) investigated by X-ray photoemission spectroscopy and low energy electron diffraction. AB - We have demonstrated that the annealing process for cleaning pyrite surfaces is a critical parameter in promoting ordering on the surface and driving surface reactivity. Furthermore, we describe a spectroscopic surface characterization of the presence or absence of the surface ordering, as indicated by the Low Energy Electron Diffraction (LEED) pattern, as a function of the surface annealing process. Complementary X-ray photoemission spectroscopy (XPS) results provide evidence that longer annealing processes of over 3 hours repair the sulfur vacancies in the pyrite, making FeS species partially disappear in favor of FeS2 species. These features play an important role in molecular adsorption. We show that in the case of the cystine amino acid on the (100) pyrite surface, the substrate structure is responsible for the chemical adsorption form. The presence of an ordered structure on the surface, as indicated by the LEED pattern, favors the cystine NH3+ chemical form, whereas the absence of the surface ordering promotes cystine NH2 adsorption due to the sulfur-deficient surface. The cystine molecule could then act by changing its chemical functionalities to compensate for the iron surface coordination. The chemical molecular adsorption form can be selected by the surface annealing conditions, implying that environmental conditions could drive molecular adsorption on mineral surfaces. These findings are relevant in several surface processes, and they could play a possible role in prebiotic chemistry surface reactions and iron-sulfur scenarios. PMID- 27711445 TI - Structures of the kinetically trapped i-motif DNA intermediates. AB - In the present work, the conformational dynamics and folding pathways of i-motif DNA were studied in solution and in the gas-phase as a function of the solution pH conditions using circular dichroism (CD), photoacoustic calorimetry analysis (PAC), trapped ion mobility spectrometry-mass spectrometry (TIMS-MS), and molecular dynamics (MD). Solution studies showed at thermodynamic equilibrium the existence of a two-state folding mechanism, whereas during the pH = 7.0 -> 4.5 transition a fast and slow phase (DeltaHfast + DeltaHslow = 43 +/- 7 kcal mol-1) with a volume change associated with the formation of hemiprotonated cytosine base pairs and concomitant collapse of the i-motif oligonucleotide into a compact conformation were observed. TIMS-MS experiments showed that gas-phase, kinetically trapped i-motif DNA intermediates produced by nanoESI are preserved, with relative abundances depending on the solution pH conditions. In particular, a folded i-motif DNA structure was observed in nanoESI-TIMS-MS for low charge states in both positive and negative ion mode (e.g., z = +/-3 to +/-5) at low pH conditions. As solution pH increases, the cytosine neutralization leads to the loss of cytosine-cytosine+ (C.CH+) base pairing in the CCC strands and in those conditions we observe partially unfolded i-motif DNA conformations in nanoESI TIMS-MS for higher charge states (e.g., z = -6 to -9). Collisional induced activation prior to TIMS-MS showed the existence of multiple local free energy minima, associated with the i-motif DNA unfolding at z = -6 charge state. For the first time, candidate gas-phase structures are proposed based on mobility measurements of the i-motif DNA unfolding pathway. Moreover, the inspection of partially unfolded i-motif DNA structures (z = -7 and z = -8 charge states) showed that the presence of inner cations may or may not induce conformational changes in the gas-phase. For example, incorporation of ammonium adducts does not lead to major conformational changes while sodium adducts may lead to the formation of sodium mediated bonds between two negatively charged sides inducing the stabilization towards more compact structures in new local, free energy minima in the gas-phase. PMID- 27711448 TI - Delayed ignition and propulsion of catalytic microrockets based on fuel-induced chemical dealloying of the inner alloy layer. AB - The delayed ignition and propulsion of catalytic tubular microrockets based on fuel-induced chemical dealloying of an inner alloy layer is demonstrated. Such timed delay motor activation process relies on the preferential gradual corrosion of Cu from the inner Pt-Cu alloy layer by the peroxide fuel. The dealloying process exposes the catalytically active Pt surface to the chemical fuel, thus igniting the microrockets propulsion autonomously without external stimuli. The delayed motor activation relies solely on the intrinsic material properties of the micromotor and the surrounding solution. The motor activation time can thus be tailored by controlling the composition of the Cu-Pt alloy layer and the surrounding media, including the fuel and NaCl concentrations and local pH. Speed acceleration in a given fuel solution is also demonstrated and reflects the continuous exposure of the Pt surface. The versatile "blastoff" control of these chemical microrockets holds considerable promise for designing self-regulated chemically-powered nanomachines with a "built-in" activation mechanism for diverse tasks.

AB - Collagen is the single most abundant protein in the extracellular matrix in the animal kingdom, with remarkable structural and functional diversity and regarded one of the most useful biomaterials. Etymologically, the term collagen comes from Greek kola 'glue' and gen 'giving birth to'. Thus, it is not surprising that the various collagens and the structures they form all serve the same purpose, to help tissues withstand stretching. Among the functions the various collagens are involved in are cell adhesion and migration, tissue repair, scaffolding and morphogenesis. Thus knowledge about the structure and properties of collagen, how they change depending on the nature of the local environment as well as the nature and specificity of collagen interactions with its partners is central to discerning the role of collagen in medical applications such as imaging, drug delivery and tissue engineering, and in the design and construction of synthetic collagen-like materials for tools in biomaterial science and nanotechnology. The main focus of this perspective is to review the molecular and packing structures of collagen and the computer simulations work performed up to now to further highlight the significance of collagen.

A novel concept of reverse polarization of the M-S intermediate allenyl cation has been realized by employing a cis-enoate assisted strategy.

AB - The binding of a Pt38-cluster on pristine graphene, mono-vacancy graphene, OH- and COOH-functionalised graphene has been investigated using DFT-calculations. Graphene containing a mono-vacancy site or OH and COOH functional groups on graphene anchor the Pt38-cluster more strongly than pristine graphene. The most favoured adsorption geometry for the cluster depends on the number of Pt-C bonds generated and the required distortion of the interacting facet. Adsorption of the cluster is associated with charge transfer between (functionalised) graphene and the Pt38-cluster, a localised charge re-distribution within the cluster and shift in the d-band centre. The modified electronic properties of the supported Pt38 cluster would imply a change in the reactivity of these supported Pt38-clusters towards adsorbates depending on the type of defect present in the support. PMID- 27711452 TI - Electronic structure and energy decomposition analyses as a tool to interpret the redox potential ranking of naphtho-, biphenyl- and biphenylene-quinone isomers. AB - By calling on modelling approaches we have performed a comparative study on the redox properties of various naphtho-, biphenyl- and biphenylene-quinone isomers. These different compounds exhibit as a whole a redox potential range between 2.09 and 2.90 V vs. Li+/Li. A specific methodology was used to decrypt the interplay among isomerism, aromaticity and antiaromaticity modifications and the stabilization/destabilization effects due to other molecular components on this key electrochemical feature for electrode materials of batteries. In particular, energy decomposition analysis, within the Quantum Theory of Atoms in Molecules, along with the electron and electron spin population changes upon reduction nicely rationalise the observed potential trends. While 1,2- and 2,3-isomers show the highest/lowest redox potential in the biphenylene-quinone series, a reverse trend is observed for the naphtho-quinone, the compound having the two carbonyl groups on distinct rings being characterized by an intermediate value in both cases. There is instead almost no differentiation between 1,2 and 2,3 isomers for the biphenyl-quinone family.

AB - An oxygen plasma treatment of ZnO nanostructures has frequently been used for obtaining a desired optoelectrical property. Nevertheless, a detailed study regarding carrier transport behaviors affected by the plasma has scarcely been managed, especially in the thin film structure, owing to its more complex physics than those of a one-dimensional nanostructure. Herein, we demonstrate an analysis of carrier transport behaviors on an oxygen plasma-treated ZnO nanofilm (50 nm thick) on a SiO2/Si substrate. By comparison with the as-grown sample, we observed drastic changes in carrier transport behavior according to the short exposure times of 30 s and 60 s. The plasma effect leading to the distinction was confirmed to originate from the bombardment of energetic ions near the surface and the diffusion of various oxygen ions and radicals into the host. The mechanism of the resulting carrier transport was comprehended through the revelation of two orthogonally directional energy band structures (surface band bending in the surface layer and localized energy bending at the grain boundary). Furthermore, we experimentally observed that the increased electrical barrier of the grain boundary, due to negatively absorbed oxygen ions, could be helpful in impeding persistent photoconductivity and in reducing dark current.

AB - Structural and selected Raman features of pristine single-walled carbon nanotubes (SWCTNs) with diameters from 0.4 to 1.2 nm and total lengths up to 2.15 nm were studied using the density functional theory (DFT) at the UB3LYP/6-31G* level. Models of different lengths (1, 4, 6 and 10 adjacent bamboo-units) of zigzag (n, 0) SWCNTs, for n ranging from 5 to 15, were studied. Highly systematic changes of individual CC bond lengths and angles along the nanotube axis were observed and described for the longest models. Predicted Raman active radial breathing mode (RBM) vibrational frequencies regularly decreased upon increasing the nanotube diameter and only a negligible effect of the tube length was observed. The changes in calculated RBM frequencies with increasing diameter were close to values estimated using empirical formulas. The experimental G-mode characteristics were reasonably well reproduced using the 4-unit model, especially for tubes with the diameter d > 1 nm. Raman features were also determined for cyclacenes representing the shortest models of SWCNTs. Calculated RBM frequencies of cyclacenes match closely the values for longer SWCNT models but are too inaccurate in the case of the G-mode. For the first time, the Raman properties of SWCNTs were also determined using the Cartesian coordinate tensor (CCT) transfer technique, thus providing reasonable frequencies of Raman active bands for long tubes consisting of 10 bamboo-units.

AB - The transformation of zwitterionic Sparfloxacin (SPX) to the neutral form is achieved by cocrystallization. Neutral forms of drugs are important for higher membrane permeability, while zwitterions are more soluble in water. The twin advantages of higher solubility/dissolution rate and good stability of neutral SPX are achieved in a molecular cocrystal compared to its zwitterionic SPX hydrate.

AB - The maximum magnetisation (saturation magnetisation) obtainable for iron oxide nanoparticles can be increased by doping the nanocrystals with non-magnetic elements such as zinc. Herein, we closely study how only slightly different synthesis approaches towards such doped nanoparticles strongly influence the resulting sub-nano/atomic structure. We compare two co-precipitation approaches, where we only vary the base (NaOH versus NH3), and a thermal decomposition route. These methods are the most commonly applied ones for synthesising doped iron oxide nanoparticles. The measurable magnetisation change upon zinc doping is about the same for all systems. However, the sub-nano structure, which we studied with Mossbauer and X-ray absorption near edge spectroscopy, differs tremendously. We found evidence that a much more complex picture has to be drawn regarding what happens upon Zn doping compared to what textbooks tell us about the mechanism. Our work demonstrates that it is crucial to study the obtained structures very precisely when "playing" with the atomic order in iron oxide nanocrystals.

AB - Recent experimental advances for the fabrication of various borophene sheets introduced new structures with a wide range of applications. Borophene is the boron atom analogue of graphene. Borophene exhibits various structural polymorphs all of which are metallic. In this work, we employed first-principles density functional theory calculations to investigate the mechanical properties of five different single-layer borophene sheets. In particular, we analyzed the effect of the loading direction and point vacancy on the mechanical response of borophene. Moreover, we compared the thermal stabilities of the considered borophene systems. Based on the results of our modelling, borophene films depending on the atomic configurations and the loading direction can yield a remarkable elastic modulus in the range of 163-382 GPa nm and a high ultimate tensile strength from 13.5 GPa nm to around 22.8 GPa nm at the corresponding strain from 0.1 to 0.21. Our study reveals the remarkable mechanical characteristics of borophene films.

AB - Lead halide based perovskite solar cells are presently the flagship among the third generation solution-processed photovoltaic technologies. The organic cation part in the perovskite plays an important role in terms of crystal structure tuning from tetragonal to trigonal or pseudocubic or vice versa depending on the organic cations used, while it also displays different microstructure. In this paper, we demonstrate the influence of the organic cation part with respect to optical properties, hysteresis behavior, and stability. This study offers a clear understanding of the perovskite properties and how they can be modulated by compositional engineering. With a rational choice, light harvesting abilities and hysteresis behavior can be controlled in these systems. The substitution of formamidinium cation by methylammonium cation allows achieving low temperature annealing and inducing stability in perovskites together with enhanced photovoltaic properties. By the use of in-situ scanning force microscopy experiments the conversion of precursors to perovskite at a particular temperature can be visualized.

AB - Na-SO2 batteries are promising power sources for energy storage systems. However, it is unclear what happens on the cathode surface at the molecular level during the discharge process. Here, we provide the working mechanism of Na-SO2 batteries through a combination of nuclear magnetic resonance (NMR) spectroscopy and first principles NMR calculations.

AB - The breaking of bonds by catalytic electrons has gained prominence very recently but has been limited to cases where electrons from external sources have been used. Here, we show that upon photoexcitation, an electron of intramolecular origin is transferred from one part of a molecule to another followed by bond cleavage and then returns to its original moiety on completion of its catalytic function. By a proper assessment of the dramatic changes in aromaticity in excited-state intermediates along the photoreaction coordinate captured by the magnetically induced current density (MICD) technique, we show that in 5 phenyltetrazole, an excited electron, which migrates from the phenyl ring to the tetrazole ring, induces bond cleavage catalytically. Using the MICD technique, we establish for the first time a link between the phenomenon of excited-state electron/charge transfer among aromatic rings and the intricate interplay of aromatic, antiaromatic and non-aromatic states.

AB - In this work, a novel polymer thermo-optic switch with loss compensation function is successfully designed and fabricated by direct UV-writing technology. The waveguide core and cladding layer material of the switch are based on the low loss fluorinated photopolymer and erbium-containing gain copolymer. The absorption loss characteristics and thermal stabilities of the core and cladding materials are studied. The optimal optical field distribution for loss compensation structures is analyzed by modifying refractive index difference between the core and cladding. The thermo-optic modulation effect of the optical signal transmission for the device is simulated. The insertion loss of the switch device is about 6 dB. The switching rise and fall time are 396.2 MUs and 461.2 MUs applied by 500 Hz square-wave voltage, respectively. The switching power is 6.5 mW, the extinction ratio of the switch is about 14 dB. The loss-compensation value of the entire chip is obtained as 1.9 dB at 1530 nm wavelength. The flexible loss-compensation multi-functional waveguide switch is appropriate for incorporation in large-scale opti-electronic integrated circuits.

AB - Graphitic carbon nitride (g-C3N4) synthesised from a urea precursor is an excellent CO2 reduction photocatalyst using [Co(bpy)n]2+ as a co-catalyst. A five fold increase in activity for the highly polymerised urea derived g-C3N4 is achieved compared to alternative precursors. Transient absorption, time-resolved and steady-state emission studies indicate that the enhanced activity is related to both an increased driving force for photoelectron transfer and a greater availability of photogenerated charges. PMID- 27711465 TI - 35Cl dynamic nuclear polarization solid-state NMR of active pharmaceutical ingredients. AB - In this work, we show how to obtain efficient dynamic nuclear polarization (DNP) enhanced 35Cl solid-state NMR (SSNMR) spectra at 9.4 T and demonstrate how they can be used to characterize the molecular-level structure of hydrochloride salts of active pharmaceutical ingredients (APIs) in both bulk and low wt% API dosage forms. 35Cl SSNMR central-transition powder patterns of chloride ions are typically tens to hundreds of kHz in breadth, and most cannot be excited uniformly with high-power rectangular pulses or acquired under conditions of magic-angle spinning (MAS). Herein, we demonstrate the combination of DNP and 1H 35Cl broadband adiabatic inversion cross polarization (BRAIN-CP) experiments for the acquisition of high quality wideline spectra of APIs under static sample conditions, and obtain signals up to 50 times greater than in spectra acquired without the use of DNP at 100 K. We report a new protocol, called spinning-on spinning-off (SOSO) acquisition, where MAS is applied during part of the polarization delay to increase the DNP enhancements and then the MAS rotation is stopped so that a wideline 35Cl NMR powder pattern free from the effects of spinning sidebands can be acquired under static conditions. This method provides an additional two-fold signal enhancement compared to DNP-enhanced SSNMR spectra acquired under purely static conditions. DNP-enhanced 35Cl experiments are used to characterize APIs in bulk and dosage forms with Cl contents as low as 0.45 wt%. These results are compared to DNP-enhanced 1H-13C CP/MAS spectra of APIs in dosage forms, which are often hindered by interfering signals arising from the binders, fillers and other excipient materials. PMID- 27711466 TI - Deposition of ZnO on bismuth species towards a rechargeable Zn-based aqueous battery. AB - Zn aqueous batteries typically suffer from poor cycle life because water soluble zincate ions are formed during the oxidation of Zn. When Zn is oxidized, most of the Zn2+ ions detach from the current collector and become electrochemically inactive, leaving the battery non-rechargeable. Numerous reports demonstrate the use of Bi2O3 as an electrode additive to enhance electrochemical performance and they attribute this phenomenon to the improvement in electrical conductivity. However, conductivity does not have an effect on the intrinsic solubility of the zincate ion. We conduct a series of characterizations to provide a comprehensive mechanistic role of Bi2O3 in the Zn electrode. We find that upon oxidation, zincate ions are formed but they relax into ZnO on the surface of the bismuth species. This work proposes that the reason for the prolonged cycle life is due to the deposition of ZnO through relaxation and this prevents losing electrochemically active materials. This finding paves the way for further improving the cycle life and understanding the mechanism of the Zn based rechargeable aqueous batteries and possibly other conversion types of rechargeable batteries. PMID- 27711467 TI - Ice nucleation on nanotextured surfaces: the influence of surface fraction, pillar height and wetting states. AB - In this work, we address the nucleation behavior of a supercooled monatomic cylindrical water droplet on nanoscale textured surfaces using molecular dynamics simulations. The ice nucleation rate at 203 K on graphite based textured surfaces with nanoscale roughness is evaluated using the mean fast-passage time method. The simulation results show that the nucleation rate depends on the surface fraction as well as the wetting states. The nucleation rate enhances with increasing surface fraction for water in the Cassie-Baxter state, while contrary behavior is observed for the case of Wenzel state. Based on the spatial histogram distribution of ice formation, we observed two pathways for ice nucleation. Heterogeneous nucleation is observed at a high surface fraction. However, the probability of homogeneous ice nucleation events increases with decreasing surface fraction. We further investigate the role of the nanopillar height in ice nucleation. The nucleation rate is enhanced with increasing nanopillar height. This is attributed to the enhanced contact area with increasing nanopillar height and the shift in nucleation events towards the three-phase contact line associated with the nanotextured surface. The ice-surface work of adhesion for the Wenzel state is found to be 1-2 times higher than that in the Cassie-Baxter state. Furthermore, the work of adhesion of ice in the Wenzel state is found to be linearly dependent on the contour length of the droplet, which is in line with that reported for liquid droplets.

AB - Gemini amphiphilic zwitterions exhibit thermotropic bicontinuous cubic liquid crystalline phases having a 3D continuous ionic domain. Incorporation of an acid into the materials led to the creation of novel electrolytes transporting protons efficiently through the 3D continuous domain. PMID- 27711469 TI - Influence of counterions on the conformation of conjugated polyelectrolytes: the case of poly(thiophen-3-ylacetic acid). AB - The addition of simple salt to a solution of conjugated polyelectrolyte can lead to substantial changes in its optical properties caused by the conformational change of the polymer chain. The effect of the addition of alkali metal and tetraalkylammonium chlorides to solutions of lithium salt of poly(thiophen-3 ylacetic acid) is investigated by NMR. The fractions of free alkali metal counterions are in agreement with predictions of the cylindrical Poisson Boltzmann cell model. On the other hand, the fractions of free tetraalkylammonium counterions deviate from the prediction of this model and diminish with increasing size of these counterions. This trend is consistent with observed ultraviolet-visible absorption spectra and measured self-diffusion coefficients of the polyion in mixtures with tetraalkylammonium salts. A transition to more constricted conformation of the polyion chain becomes more pronounced with the lengthening of alkyl groups in the added tetraalkylammonium cation. Taking into account the obtained fractions of free counterions, existing thermodynamic data are reanalysed in order to determine thermodynamic parameters for binding of different counterions to the polyion. This analysis shows that standard enthalpies of binding of alkali metal counterions are distinctively different, which is most probably related to differences in hydration shells of counterions. On the other hand, such an analysis fails in the case of tetraalkylammonium chlorides where obviously more complex changes take place. PMID- 27711470 TI - Catalytic effects of silver plasmonic nanoparticles on the redox reaction leading to ABTS+ formation studied using UV-visible and Raman spectroscopy. AB - ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) is a compound extensively employed to evaluate the free radical trapping capacity of antioxidant agents and complex mixtures such as biological fluids or foods. This evaluation is usually performed by using a colourimetric experiment, where preformed ABTS radical cation (ABTS+) molecules are reduced in the presence of an antioxidant causing an intensity decrease of the specific ABTS+ UV-visible absorption bands. In this work we report a strong effect of silver plasmonic nanoparticles (Ag NPs) on ABTS leading to the formation of ABTS+. The reaction of ABTS with Ag NPs has been found to be dependent on the interfacial and plasmonic properties of NPs. Specifically, this reaction is pronounced in the presence of spherical nanoparticles prepared by the reduction of silver nitrate with hydroxylamine (AgH) and in the case of star-shaped silver nanoparticles (AgNS). On the other hand, spherical nanoparticles prepared by the reduction of silver nitrate with citrate apparently do not react with ABTS. Additionally, the formation of ABTS+ is investigated by surface-enhanced Raman scattering (SERS) and the assignment of the most intense vibrational bands of this compound is performed. The SERS technique enables us to detect this radical cation at very low concentrations of ABTS (~2 MUM). Altogether, these findings allow us to suggest the use of ABTS/Ag NPs-systems as reliable and easy going substrates to test the antioxidant capacity of various compounds, even at concentrations much lower than those usually used in the spectrophotometric assays. Moreover, we have suggested that ABTS could be employed as a suitable agent to investigate the interfacial and plasmonic properties of the metal nanoparticles and, thus, to characterize the nanoparticle metal systems employed for various purposes. PMID- 27711471 TI - The influence of solution environment on the nucleation kinetics and crystallisability of para-aminobenzoic acid. AB - The influence of solvent type on the solution thermodynamics, nucleation-kinetics and crystal growth of alpha para-aminobenzoic acid (PABA) crystallising from supersaturated ethanol, acetonitrile and water solutions, is examined using poly thermal analysis of the metastable zone width. Application of a recently proposed model for analysis of crystallisation kinetics (J. Cryst. Growth, 2010, 312, 698 704) indicates a solvent and concentration dependence of the nucleation mechanism and key nucleation parameters for the alpha form of PABA. The mechanism of nucleation is found to change from instantaneous to progressive with decreasing concentration and also when changing the solvent from ethanol to acetonitrile to water. The dependence of the nucleation mechanism is correlated to the kinetic component of the nucleation rate through calculated values of instantaneously nucleated crystallites, which increase from 1.40 * 109 m-3 in ethanol to 1.08 * 1010 m-3 in acetonitrile to 2.58 * 1010 m-3 in water. This in combination with low calculated number concentrations of interfacial tension between 1.13 and 2.71 mJ m-2, supports the conclusion that the kinetic component of the nucleation rate is more limiting when crystallising PABA from ethanol solutions in comparison to water solutions. This finding is further supported by molecular dynamics simulations of the solvation free energy of PABA, which is found to be greatest in water, -42.4 kJ mol-1 and lowest in ethanol, -58.5 kJ mol-1.

AB - A novel cascade reaction of alkynyl-tethered alpha-iminodiazoacetates has been developed, which provides a general access to both multi-substituted and fused pyrroles in high yields with a broad substrate scope. The gamma-imino carbene is proposed as the key intermediate in this divergent reaction and followed by unpresented transformations. PMID- 27711473 TI - Excited-state intramolecular proton transfer and conformational relaxation in 4' N,N-dimethylamino-3-hydroxyflavone doped in acetonitrile crystals. AB - The effect of intermolecular interactions on excited-state intramolecular proton transfer (ESIPT) in 4'-N,N-dimethylamino-3-hydroxyflavone (DMHF) doped in acetonitrile crystals was investigated by measuring its temperature dependence of steady-state fluorescence excitation and fluorescence spectra and picosecond time resolved spectra. The relative intensity of emission from the excited state of the normal form (N*) to that from the excited state of the tautomer form (T*) and spectral features changed markedly with temperature. Unusual changes in the spectral shift and spectral features were observed in the fluorescence spectra measured between 200 and 218 K, indicating that a solid-solid phase transition of DMHF-doped acetonitrile crystals occurred. Time-resolved fluorescence spectra suggested conformational relaxation of the N* state competed with ESIPT after photoexcitation and the ESIPT rate increased with temperature in the low temperature phase of acetonitrile. However, the intermolecular interaction of N* with acetonitrile in the high-temperature phase markedly stabilized the potential minimum of the fluorescent N* state and slowed the ESIPT. This stabilization can be explained by reorganization of acetonitrile originating from the strong electric dipole-dipole interaction between DMHF and acetonitrile molecules. PMID- 27711474 TI - Conformation controlled turn on-turn off phosphorescence in a metal-free biluminophore: thriving the paradox that exists for organic compounds. AB - The legacy of phosphorescence from expensive organometallic compounds has inspired researchers to develop efficient metal-free organic phosphors. Although organic phosphors offer a cheaper alternative, the long-lived triplets of organic phosphors that are primarily consumed by vibrational dissipation need to be adequately suppressed, and this provides an opportunity to design new organic entities, at par with the organometallic compounds, based on conformational control and incorporation of useful functional groups to alter their emissive properties, especially phosphorescence. Here, we have achieved a proficient dual state emission, underlining the key design rule of conformational control in an organic molecular platform for 2-(6-chlorobenzo[d]thiazol-2-yl)-1H benzo[de]isoquinoline-1,3(2H)-dione (CBIQD). In contrast to other known naphthalimides, the system limiting access to non-radiative triplet states is achieved by steric encumbrance which exhibits strong phosphorescence. Here, in addition to strong fluorescence (from planar conformer), phosphorescence is unlocked by suppression of non-radiative channels from the non-planar conformer in glassy solvents (77 K) and when embedded in a polymer matrix of poly(methyl methacrylate) (PMMA) at RT. The spectroscopic delineation of adopted geometry and optical property relationship is sought by a steric approach, extent of intramolecular charge transfer (ICT), presence of carbonyl groups, directed heavy atom effect and the spin-orbit coupling (SOC) invoked by -S- and -Cl atoms. Time dependent density functional theory (TD-DFT) is used to explain the favourable mechanistic path for the decay of excited states (ESs) leading to phosphorescence from a non-planar conformer and fluorescence from a planar conformer. The spectacular access to the radiative singlet and triplet states suggests that there is less scope for loss channels. The phosphorescence of the CBIQD-PMMA system may find use in other biomedical applications due to the biocompatibility of each component.

PMID- 27711476 TI - Role of ion hydration for the differential capacitance of an electric double layer. AB - The influence of soft, hydration-mediated ion-ion and ion-surface interactions on the differential capacitance of an electric double layer is investigated using Monte Carlo simulations and compared to various mean-field models. We focus on a planar electrode surface at physiological concentration of monovalent ions in a uniform dielectric background. Hydration-mediated interactions are modeled on the basis of Yukawa potentials that add to the Coulomb and excluded volume interactions between ions. We present a mean-field model that includes hydration mediated anion-anion, anion-cation, and cation-cation interactions of arbitrary strengths. In addition, finite ion sizes are accounted for through excluded volume interactions, described either on the basis of the Carnahan-Starling equation of state or using a lattice gas model. Both our Monte Carlo simulations and mean-field approaches predict a characteristic double-peak (the so-called camel shape) of the differential capacitance; its decrease reflects the packing of the counterions near the electrode surface. The presence of hydration-mediated ion-surface repulsion causes a thin charge-depleted region close to the surface, which is reminiscent of a Stern layer. We analyze the interplay between excluded volume and hydration-mediated interactions on the differential capacitance and demonstrate that for small surface charge density our mean-field model based on the Carnahan-Starling equation is able to capture the Monte Carlo simulation results. In contrast, for large surface charge density the mean-field approach based on the lattice gas model is preferable.

AB - In this paper, the structural, electronic and magnetic properties of fully and partially surface modified SiGe nanosheets (NSs) have been investigated using first-principles calculations based on density functional theory. The results demonstrate that the electronic and magnetic properties of SiGe NSs can be tuned by decorating H, Cl and F atoms on Si sites in SiGe NSs. It is shown that by decorating their surface with H, F, and Cl atoms, H-SiGe, F-SiGe, and Cl-SiGe NSs in FM states are predicted to behave as a semiconductor, half-metal, and metal, respectively. The diverse electronic and magnetic properties define the potential applications of SiGe nanosheets in electronics and spintronics. PMID- 27711478 TI - Observation of a new channel, the production of CH3, in the abstraction reaction of OH radicals with acetaldehyde. AB - Using laser flash photolysis coupled to photo-ionization time-of-flight mass spectrometry (PIMS), methyl radicals (CH3) have been detected as primary products from the reaction of OH radicals with acetaldehyde (ethanal, CH3CHO) with a yield of ~15% at 1-2 Torr of helium bath gas. Supporting measurements based on laser induced fluorescence studies of OH recycling in the OH/CH3CHO/O2 system are consistent with the PIMS study. Master equation calculations suggest that the origin of the methyl radicals is from prompt dissociation of chemically activated acetyl products and hence is consistent with previous studies which have shown that abstraction, rather than addition/elimination, is the sole route for the OH + acetaldehyde reaction. However, the observation of a significant methyl product yield suggests that energy partitioning in the reaction is different from the typical early barrier mechanism where reaction exothermicity is channeled preferentially into the newly formed bond. The master equation calculations predict atmospheric yields of methyl radicals of ~9%. The implications of the observations in atmospheric and combustion chemistry are briefly discussed.

AB - Oligosaccharide-based block copolymers (OBCPs) are synthesized by thiol click conjugation using reducing-end thiol-containing xyloglucooligosaccharides and maleimide- or bromomaleimide-terminated polycaprolactone. The self-assembled OBCPs in aqueous solution lead to redox-sensitive micelles with different responsiveness. This distinguishing feature allows us to control the release of entrapped hydrophobic Nile red by mixing both OBCPs. PMID- 27711480 TI - Benchmark values of chemical potential and chemical hardness for atoms and atomic ions (including unstable anions) from the energies of isoelectronic series. AB - We present benchmark values for the electronic chemical potential and chemical hardness from reference data for ionization potentials and electron affinities. In cases where the energies needed to compute these quantities are not available, we estimate the ionization potential of the metastable (di)anions by extrapolation along the isoelectronic series, taking care to ensure that the extrapolated data satisfy reasonable intuitive rules to the maximum possible extent. We also propose suitable values for the chemical potential and chemical hardness of zero-electron species. Because the values we report are faithful to the trends in accurate data on atomic energies, we believe that our proposed values for the chemical potential and chemical hardness are ideally suited to conceptual studies of chemical trends across the periodic table. The critical nuclear charge (Z critical) of the isoelectronic series with 2 < N < 96 has also been reported for the first time. PMID- 27711481 TI - Theoretical and experimental investigation on structural, electronic and magnetic properties of layered Mn5O8. AB - We have investigated the crystal, electronic, and magnetic structures of Mn5O8 by means of state-of-the-art density functional theory calculations and neutron powder diffraction (NPD) measurements. This compound stabilizes in the monoclinic structure with space group C2/m where the Mn ions are in the distorted octahedral and trigonal prismatic coordinations with oxygen atoms. The calculated structural parameters based on total energy calculations are found to be in excellent agreement with low temperature NPD measurements when we accounted for the correct magnetic structure and Coulomb correlation effect in the computation. Using fully relativistic generalized-gradient approximation with Hubbard U (GGA+U) we found that the magnetic ordering in Mn5O8 is A-type antiferromagnetic and the direction of the easy axis is [1 0 0] in agreement with susceptibility and NPD measurements. However, the calculation without the inclusion of Hubbard U leads to ferrimagnetic half metal as a ground state contradictory to experimental findings, indicating the presence of a strong Coulomb correlation effect in this material. The GGA calculation without the Coulomb correction effect itself is sufficient to reproduce the experimentally observed magnetic moments in various Mn sites. We found that Mn in this material exhibits mixed valence behavior with 2+ and 4+ oxidation states reflecting different magnetic moments in the Mn sites. We explored the electronic band characteristics using total, site-, and orbital projected density of states which emphasized the mixed-valent nature of Mn. A dominant Mn 3d character of the density of states at Fermi energy is the origin for the metallic behavior of Mn5O8. The bond strength analysis based on the crystal orbital Hamiltonian population between constituents indicates strong anisotropy in the bonding behavior which results from the layered nature of its crystal structure. Our bonding analysis shows that there is a noticeable covalent bond between Mn 3d-O 2p states which stabilizes the observed low symmetric structure. Our experimental findings and theoretical predictions suggest that Mn5O8 can be classified as a strongly correlated mixed valent antiferromagnetic metal. PMID- 27711482 TI - Photocatalytic oxidation of methane over SrCO3 decorated SrTiO3 nanocatalysts via a synergistic effect. AB - Because of the high C-H bond energy as well as the non-polar feature of CH4 molecules, oxidation of methane under mild conditions remains a challenging task for both C1 utilization and atmospheric environmental cleansing. Here we report that by using a sol-gel method SrCO3 decorated SrTiO3 nanocatalysts (SrTiO3-S) with an average particle size of ~25 nm can be readily prepared, which surprisingly show efficient performance for photocatalytic oxidation of methane with the activity close to fourfold of P25, a benchmark photocatalyst. Further investigation revealed a synergistic effect between SrCO3 and SrTiO3 when combined together into a composite material as both of which are totally inactive for methane oxidation if used alone. Gas adsorption characterization disclosed that the SrCO3 can adsorb methane and cannot adsorb carbon dioxide, whereas the SrTiO3 will preferentially adsorb CO2 instead of CH4. Photocurrent and photoluminescence measurements indicate that SrCO3 exhibits a negligible photocurrent response relative to the SrTiO3 semiconductor under simulated solar light illumination but the formation of the SrCO3/SrTiO3 junction structure (SrTiO3-S) helps reduce surface recombination of the photogenerated electrons and holes. All these results refer to the synergistic mechanism in which the SrCO3 acts as a trapping agent to adsorb methane and weaken its C-H bond while the SrTiO3 acts as a photocatalyst to activate and oxidize methane under light illumination. The underlying photooxidation mechanism is further investigated with the aid of in situ electron paramagnetic resonance and infrared spectroscopy. PMID- 27711483 TI - Electronic and optical properties of MAPbX3 perovskites (X = I, Br, Cl): a unified DFT and GW theoretical analysis. AB - Materials engineering is a key for the enhancement of photovoltaics technology. This is particularly true for the novel class of perovskite solar cells. Accurate theoretical modelling can help establish general trends of behavior when addressing structural changes. Here, we consider the effects due to halide substitution in organohalide CH3NH3PbX3 perovskites exploring the halide series with X = Cl, Br, I. For this task, we use accurate DFT and GW methods including spin-orbit coupling. We find the expected band gap increase when moving from X = I to Cl, in line with the experimental data. Most notably, the calculated absorption coefficients for I, Br and Cl are nicely reproducing the behavior reported experimentally. A common feature of all the simulated band structures is a significant Rashba effect. This is similar for MAPbI3 and MAPbBr3 while MAPbCl3 shows in general a reduced Rashba interaction coefficient. Finally, a monotonic increase of the exciton reduced masses is calculated when moving from I to Br to Cl, in line with the stronger excitonic character of the lighter perovskite halides. PMID- 27711484 TI - Thermodynamics and kinetics of carbon deposits on cobalt: a combined density functional theory and kinetic Monte Carlo study. AB - We have built a lattice gas model for cobalt-carbon interaction to investigate the thermodynamics and kinetics of carbon deposition on Co(0001) surfaces. The formation of carbon structures on cobalt is considered to be one of the causes of deactivation of a cobalt Fischer-Tropsch (FT) catalyst. The formation of graphene - the most thermodynamically stable phase under FT conditions - is kinetically inhibited during the first 30 hours of exposure of the surface to carbon, while the build-up of surface carbide is the fastest reaction. Our simulations clearly show that the kinetics of carbon deposition is the result of two competing effects: a fast subsurface diffusion and a slower surface diffusion to form a carbon-carbon bond.

AB - The influence of urea on the conducting salt lithium bis (trifluoromethanesulfonyl)-imide (LiTFSI) in terms of lithium ion coordination numbers and lithium ion transport properties is studied via atomistic molecular dynamics simulations. Our results indicate that the presence of urea favors the formation of a deep eutectic electrolyte with pronounced ion conductivities which can be explained by a competition between urea and TFSI in occupying the first coordination shell around lithium ions. All simulation findings verify that high urea concentrations lead to a significant increase of ionic diffusivities and an occurrence of relatively high lithium transference numbers in good agreement with experimental results. The outcomes of our study point at the possible application of deep eutectic electrolytes as ion conducting materials in lithium ion batteries.

AB - We investigate the motion of electrically charged metallic nano- and microparticles produced by laser ablation in He gas and injected into superfluid helium. In the presence of a vertical static electric field, the particles either perform a repetitive shuttle-like motion transporting the charge across the liquid-gas interface or become trapped under the free surface of liquid He and coalesce into long filaments and complex two-dimensional mesoscopic networks. A classical electrohydrodynamic model is used to describe the motion of charged microparticles in superfluid He. The resulting filaments and networks are analyzed using electron microscopy. It is demonstrated that each filament is in fact composed of a large number of nanowires with a characteristic diameter of order of 10 nm and extremely large aspect ratios.

AB - Particle size significantly affects the properties and therefore the potential applications of multiferroics. However, is there special particle size effect in BiFeO3, which has a spiral modulated spin structure? This is still under investigation for sub-5 nm BiFeO3. In this report, the structural, electronic and magnetic properties are investigated for chemically synthesized BiFeO3 nanoparticles with an average size of 3 nm. We observed nanotwinning features in the specific size regime of the nanoparticles (2-4 nm). A weak Bi-O-Fe coordination and weak covalent nature has been observed in the nanoparticles through high-resolution electron energy loss spectroscopy and theoretical analysis, confirming that BiFeO3 nanoparticles a retain rudimentary R3c phase even at sub-5 nm dimensions. The R3c phase of sub-5 nm BiFeO3 nanoparticles has also been confirmed using Raman spectroscopy and Raman mapping of the vibrational modes. The nanoparticles display cluster spin glass, room temperature ferromagnetism, and a metamictization-davidite phase. The observation of weak magnetic entropy features confirmed the presence of a weak correlation between the magnetic and ferroelectric components. To support our experimental observations, we have simulated a sub-5 nm BiFeO3 nanocluster. Using density functional theory, the ferromagnetic ground state and the presence of a weak covalent nature in the nanocluster is established considering the first Brillouin zone, thus confirming our experimental results. Finding of new physicochemical features in sub-5 nm BiFeO3 would be beneficial for the understanding of the fundamental physical and chemical science as well as potential device development.

AB - Vertically stacked van der Waals (vdW) heterojunctions of two-dimensional (2D) transition metal dichalcogenides (TMDs) have attracted a great deal of attention due to their fascinating properties. In this work, we report two important gate tunable phenomena in new artificial vdW p-n heterojunctions created by vertically stacking p-type multilayer ReSe2 and n-type multilayer WS2: (1) well-defined strong gate-tunable diode-like current rectification across the p-n interface is observed, and the tunability of the electronic processes is attributed to the tunneling-assisted interlayer recombination induced by majority carriers across the vdW interface; (2) the distinct ambipolar behavior under gate voltage modulation both at forward and reverse bias voltages is found in the vdW ReSe2/WS2 heterojunction transistors and a corresponding transport model is proposed for the tunable polarity behaviors. The findings may provide some new opportunities for building nanoscale electronic and optoelectronic devices.

AB - The development of advanced materials for CO2 capture is of great importance for mitigating climate change. In this paper, we outline our discovery that calcium decorated carbon nanostructures, i.e., zigzag graphene nanoribbons (ZGNRs), carbyne, and graphyne, have great potential for selective CO2 capture, as demonstrated via first-principles calculations. Our findings show that Ca decorated ZGNRs can bind up to three CO2 molecules at each Ca atom site with an adsorption energy of ~-0.8 eV per CO2, making them suitable for reversible CO2 capture. They adsorb CO2 molecules preferentially, compared with other gas molecules such as H2, N2, and CH4. Moreover, based on equilibrium thermodynamical simulations, we confirm that Ca-decorated ZGNRs can capture CO2 selectively from a gas mixture with a capacity of ~4.5 mmol g-1 under ambient conditions. Similar results have been found in other carbon nanomaterials, indicating the generality of carbon based nanostructures for selective CO2 capture under ambient conditions.

PMID- 27711493 TI - Raman excess spectroscopy vs. principal component analysis: probing the intermolecular interactions between chiral molecules and imidazolium-based ionic liquids. AB - Raman spectroscopy is a very sensitive and specific measurement tool for probing intermolecular interaction structures. As imidazolium-based ionic liquids can favorably be used for enantioseparation, in this work two approaches for Raman signal analysis, namely by means of excess spectra and principal component analysis (PCA), are compared to extract detailed information about the interaction structure of the enantiomers d- and l-glucose in an aqueous solution of the ionic liquid [EMIM][EtSO4]. In contrast to the excess calculations, the loadings obtained from PCA lead to significant results since the interactions are weighted by their strength and significance. Moreover, the analysis of the weighted vibrations in the loadings indicate that hydrogen bonds are particularly formed between the ethyl sulphate anion of [EMIM][EtSO4] and the hydrogen atom of the OH-group at the C6-atom of glucose. PMID- 27711494 TI - Outstanding surface plasmon resonance performance enabled by templated oxide gratings. AB - Here we report a simple and scalable soft-lithography-based templating technology for fabricating Au-covered oxide (titania and zirconia) gratings by using DVDs as a structural template. The resulting plasmonic gratings simultaneously exhibit very high surface plasmon resonance (SPR) sensitivity (up to ~940 nm per refractive index unit, nm per RIU) and figure of merit (FOM, up to 62.5). The effects of thermal annealing of the templated oxide gratings on their final plasmonic properties have been systematically investigated by both experiments and finite-difference time-domain (FDTD) simulations. Higher SPR sensitivities and slightly reduced FOMs have been observed for the annealed gratings. Additionally, the amplitude of the SPR dips gradually decreases with increasing annealing temperatures. Scanning electron microscopy and X-ray diffraction show that the annealing process enlarges the crystal domain sizes of the oxides and smoothens the final plasmonic grating surface. Systematic FDTD simulations reveal that the SPR properties (e.g., dip amplitude) of Au-covered oxide gratings are significantly affected by the deformation of the track-pitch structure caused by thermal annealing, agreeing with the experimental results. The outstanding SPR performance combined with the high thermal stability of the crystalline oxides could make the templated plasmonic gratings a promising SPR platform for many important sensing applications, such as in situ probing heterogeneous catalytic reactions under realistic conditions.

AB - Crown ethers, as a kind of heterocycle, have been the subject of great interest over recent decades due to their selective capability to bind to metal cations. The use of a constant crown ether, such as naphtho-15-crown-5 (N15C5), and varied metal cations (Li+, Na+, K+, Be2+, Mg2+, Ca2+, Co2+, Ni2+, Cu2+) makes it possible to determine the contributions of the metal cations to nonlinear optical (NLO) responses and to design an appropriate NLO-based cation detector. N15C5 and its metal cation derivatives have been systematically investigated by density functional theory. It is found that the dependency of the first hyperpolarizability relies on the metal cation, especially for transition metals. The decrease of the first hyperpolarizabilities for alkali metal cation derivatives is due to their relatively low oscillator strengths, whereas the significant increase of the first hyperpolarizabilities for transition metal cation derivatives can be further illustrated by their low transition energies, large amplitudes and separate distributions of first hyperpolarizability density. Thus, the alkali metal and transition metal cations are distinguishable and the transition metal cations are easier to detect by utilizing the variations in NLO responses.

AB - A strategy based on tandem alkynylation of o-hydroxyarylenaminones followed by intramolecular cyclization has been developed to generate a diverse array of 3 alkynyl chromones.

PMID- 27711497 TI - Induction of unidirectional pi-electron rotations in low-symmetry aromatic ring molecules using two linearly polarized stationary lasers. AB - A new laser-control scenario of unidirectional pi-electron rotations in a low symmetry aromatic ring molecule having no degenerate excited states is proposed. This scenario is based on dynamic Stark shifts of two relevant excited states using two linearly polarized stationary lasers. Each laser is set to selectively interact with one of the two electronic states, the lower and higher excited states are shifted up and down with the same rate, respectively, and the two excited states become degenerate at their midpoint. One of the four control parameters of the two lasers, i.e. two frequencies and two intensities, determines the values of all the other parameters. The direction of pi-electron rotations, clockwise or counter-clockwise rotation, depends on the sign of the relative phase of the two lasers at the initial time. An analytical expression for the time-dependent expectation value of the rotational angular momentum operator is derived using the rotating wave approximation (RWA). The control scenario depends on the initial condition of the electronic states. The control scenario with the ground state as the initial condition was applied to toluene molecules. The derived time-dependent angular momentum consists of a train of unidirectional angular momentum pulses. The validity of the RWA was checked by numerically solving the time-dependent Schrodinger equation. The simulation results suggest an experimental realization of the induction of unidirectional pi electron rotations in low-symmetry aromatic ring molecules without using any intricate quantum-optimal control procedure. This may open up an effective generation method of ring currents and current-induced magnetic fields in biomolecules such as amino acids having aromatic ring molecules for searching their interactions. PMID- 27711498 TI - Exploration of the phase diagram of liquid water in the low-temperature metastable region using synthetic fluid inclusions. AB - We present new experimental data of the low-temperature metastable region of liquid water derived from high-density synthetic fluid inclusions (996-916 kg m 3) in quartz. Microthermometric measurements include: (i) prograde (upon heating) and retrograde (upon cooling) liquid-vapour homogenisation. We used single ultrashort laser pulses to stimulate vapour bubble nucleation in initially monophase liquid inclusions. Water densities were calculated based on prograde homogenisation temperatures using the IAPWS-95 formulation. We found retrograde liquid-vapour homogenisation temperatures in excellent agreement with IAPWS-95. (ii) Retrograde ice nucleation. Raman spectroscopy was used to determine the nucleation of ice in the absence of the vapour bubble. Our ice nucleation data in the doubly metastable region are inconsistent with the low-temperature trend of the spinodal predicted by IAPWS-95, as liquid water with a density of 921 kg m-3 remains in a homogeneous state during cooling down to a temperature of -30.5 degrees C, where it is transformed into ice whose density corresponds to zero pressure. (iii) Ice melting. Ice melting temperatures of up to 6.8 degrees C were measured in the absence of the vapour bubble, i.e. in the negative pressure region. (iv) Spontaneous retrograde and, for the first time, prograde vapour bubble nucleation. Prograde bubble nucleation occurred upon heating at temperatures above ice melting. The occurrence of prograde and retrograde vapour bubble nucleation in the same inclusions indicates a maximum of the bubble nucleation curve in the rho-T plane at around 40 degrees C. The new experimental data represent valuable benchmarks to evaluate and further improve theoretical models describing the p-V-T properties of metastable water in the low-temperature region.

PMID- 27711501 TI - First exploration of freestanding and flexible Na2+2xFe2-x(SO4)3@porous carbon nanofiber hybrid films with superior sodium intercalation for sodium ion batteries. AB - The design of a freestanding electrode is the key to the development of energy storage devices with superior electrochemical performance and mechanical durability. Herein, we propose a highly-scalable strategy for the facile synthesis of a freestanding alluaudite Na2+2xFe2-x(SO4)3@porous carbon-nanofiber hybrid film, which is used as a self-supported and flexible electrode for sodium ion batteries. By the combined use of electrospinning and electrospraying, the freestanding hybrid film is constructed in the form of sulfate nanoparticles enwrapped in highly porous graphitic-like carbon-nanofibers. The multimodal porous architecture of the freestanding hybrid film ensures its superiority in mechanical flexibility and structural stability during repeated electrochemical processes, which meets the long-standing challenge of practical application. Moreover, both the highly conductive and porous framework and the nanoscale particles are favorable for promoting fast electron/ion transport capability. Compared with other carbon based supports such as graphene (GA), carbon nanotubes (CNTs) and active carbons (ACs), the flexible carbon nanofiber shows better interaction with electrochemical active materials and superior electrochemical properties. It retains over 95% of the capacity after five hundred cycles at alternate rates of 40C and 5C, which demonstrates the superior ultralong time and high-rate cycling capability. Therefore, the present work provides a facile and highly scalable strategy for the design and fabrication of high-performance freestanding sulfate cathodes for advanced sodium ion batteries.

AB - Investigations carried out at MP2 and CCSD(T) levels of theory show that water dimers can compete with formic and sulfuric acids in catalyzing the isomerization of methoxy radicals in the lower troposphere. The rate coefficients for water catalyzed reactions showed opposite temperature dependence to that of acid catalyzed reactions and they were found to play an important role in determining the relative impacts of these catalysts under different atmospheric conditions. PMID- 27711503 TI - Ab initio study of hydrogen chemisorption in nitrogen-doped carbon nanotubes. AB - The electronic structure of single walled nitrogen-doped carbon nanotubes is calculated by first principles using density functional theory within the supercell approach with periodic boundary conditions. The effect of the adsorption of hydrogen atoms on different sites, relative to the position of the nitrogen atom, is explicitly taken into account. Both non-chiral and chiral geometries are analyzed. The obtained band structure shows that the non-chiral (6,0) nanotube is a semimetal under all different doping and adsorption configurations treated. The non-chiral (10,0) nanotube behaves mostly as a semiconductor, with the band gap width modulated by nitrogen doping and the relative position of the adsorbed hydrogen atom. The increase of substitutional N doping from one to three atoms per cell turns a (6,5) single-walled carbon nanotube from a semiconductor into a semimetal at zero temperature. Optical absorption related to carrier transitions between the calculated states is investigated from the imaginary part of the dielectric function, constructed with the use of the calculated Kohn-Sham states. The importance of the variation of the relative position of the adsorbed hydrogen atom on the chemical and physical properties investigated is particularly highlighted. PMID- 27711504 TI - Thermoelectric properties of fullerene-based junctions: a first-principles study. AB - This study is built on density functional calculations in combination with the non-equilibrium Green's function, and we probe the thermoelectric transport mechanisms through C60 molecules anchored to Al nano-electrodes in three different ways, such as, the planar, pyramidal, and asymmetric surfaces. When the electrode is switched from the planar and pyramidal surfaces, the electrical conductance (sigma) and electron's thermal conductance (kappael) decrease almost two orders of magnitude due to the reduction of the molecule-electrode contact coupling, whereas the Seebeck coefficients (S) are reduced by ~55%. Furthermore, the maximum electron's thermoelectric figure of merit (ZelT = S2sigmaT/kappael, assuming a vanishing phonon's thermal conductance) is about 0.12 in the asymmetric junction. In particular, all sigma, S, kappael, and ZelT increase along with the average temperature (T) in all C60-junctions, although their growth is really quite negligible in the pyramidal junction because the Fermi level is far away from the frontier orbitals. In addition, when the strain increases from the compressive (-1.0 A) to tensile (1.0 A) strain, the Seebeck coefficient in the planar junction increases drastically, while the Seebeck coefficients in the asymmetric and pyramidal junctions reach their maximum values at 0.2 A tensile and -0.4 A compressive strains, respectively. This is because the Seebeck coefficient is inversely proportional to the magnitudes and proportional to the slopes of the transmission spectrum around the Fermi level. Finally, it is found that the shift of the Fermi level is an effective scheme to obtain the maximum ZelT of any molecular junction, including fullerene-based junctions.

AB - Two-dimensional (2D) carbonitrides have attracted intense interest because of their intriguing physical and chemical properties. One such 2D system is the so called phthalo-carbonitride (pc-C3N2) with stoichiometry C3N2 and an extended network of phthalocyanine-like cores. Here we use first-principles calculations to study pc-C3N2 sheets with Al, Zn, or Cu atoms attached at the cores. We describe the structural details of various possible geometries and probe the electronic properties of the most stable configurations. The decorated sheets are metallic, with the exception of the Zn case, which is a semiconductor with a small energy band gap. Moreover, the Cu-laden monolayers bear finite magnetization. These key properties highlight the potential of C3N2-based 2D materials as multi-functional components in various applications. PMID- 27711507 TI - Versatile fabrication of a superhydrophobic and ultralight cellulose-based aerogel for oil spillage clean-up. AB - To deal with marine oil spillage and chemical leakage issues, a highly efficient absorbent (cellulose based aerogel) with a low density (rho < 0.034 g cm-3, phi > 98.5%) and high mechanical strength was fabricated via a novel physical-chemical foaming method, plasma treatment and subsequent silane modification process. This aerogel has a perfect 3D skeleton and interconnected pores similar to honeycomb, which are favorable to oil adsorption and storage. More importantly, without introducing additional micro/nanoparticles, the rough micro/nano structure of the surface was directly constructed using plasma irradiation in this study. The low surface energy substrate was further introduced using a simple physical-soaking method and the resulting aerogel exhibited excellent superhydrophobicity (WCA > 156 degrees ) and superoleophilicity (OCA = 0 degrees ), which can selectively and efficiently absorb various oils or organic solvents from polluted water. In addition, this aerogel has a high storage capacity and absorption capacity (up to 4300% and 99% of its weight and volume, respectively). More interestingly, this aerogel exhibits excellent mechanical abrasion resistance and corrosion resistance even in strong acid, alkali solution and salt marine environment. The aerogel could be reused more than 30 times after removal of the absorbed oil by rinsing with ethanol. PMID- 27711508 TI - How do random superficial defects influence the electro-oxidation of glycerol on Pt(111) surfaces? AB - The glycerol electrooxidation reaction (GEOR) has attracted huge interest in the last decade due to the very low price and availability of this polyol. In this work, we studied the GEOR on Pt(111) electrodes by introducing different densities of random defects. Our results showed that the generation of defects on Pt(111) slightly modified the GEOR onset potential, however it generates changes in the voltammetric oxidation charges and also in the relative production of CO2 to carbonyl containing compounds, C[double bond, length as m-dash]O. The voltammetric profiles in the forward scan show two oxidation peaks. FTIR data show that the first one is connected with the GlOH dissociative adsorption to form CO (and others intermediates) while the second one, at higher potentials, matches the onsets of the CO oxidation to CO2 and the C[double bond, length as m dash]O production. FTIR also confirms that the lower activity of defected electrodes at lower potentials is connected to a higher CO poisoning. DFT calculations show that the presence of CO molecules on a Pt defected surface keeps water and GlOH molecules far from the surface and linked by H bonds. This paper is the last of a series of three works where we explore the GEOR on an important number of different Pt surfaces. These works show that it is difficult to oxidize GlOH at potentials lower than 0.6 V (under our experimental conditions) without suffering an important electrode poisoning (mainly by CO). Since the structure of nanoparticles might be mimicked by defected single crystals, these sets of reports provide a considerable amount of information concerning the influence of such surfaces towards GlOH reaction in acidic media. Therefore, if the well-known "nano"-effect does not produce substantial changes in the activity of Pt materials, they are not useful to be applied in a Direct Glycerol Fuel Cell (DGFC). On the other hand, it is very interesting that the density of electrode defects permits us to tune the relative production of CO2 to C[double bond, length as m-dash]O. PMID- 27711509 TI - Nonresonant electronic transitions induced by vibrational motion in light-induced potentials. AB - We find a new mechanism of electronic population inversion using strong femtosecond pulses, where the transfer is mediated by vibrational motion on a light-induced potential. The process can be achieved with a single pulse tuning its frequency to the red of the Franck-Condon window. We show the determinant role that the gradient of the transition dipole moment can play on the dynamics, and extend the method to multiphoton processes with odd number of pulses. As an example, we show how the scheme can be applied to population inversion in Na2. PMID- 27711510 TI - An attempt to correlate surface physics with chemical properties: molecular beam and Kelvin probe investigations of Ce1-xZrxO2 thin films. AB - What is the correlation between physical properties of the surfaces (such as surface potential, electronic nature of the surface), and chemical and catalysis properties (such as chemisorption, sticking probability of surface)? An attempt has been made to explore any correlation that might exist between the physical and chemical properties of thin film surfaces. Kelvin probe microscopy (KPM) and the molecular beam (MB) methods were employed to carry out the surface potential, and oxygen adsorption and oxygen storage capacity (OSC) measurements on Ce1 xZrxO2 thin films. A sol-gel synthesis procedure and spin-coating deposition method have been applied to make continuous nanocrystalline Ce1-xZrxO2 (x = 0-1) (CZ) thin films with uniform thickness (35-50 nm); however, surface roughness and porosity inherently changes with CZ composition. MB studies of O2 adsorption on CZ reveal high OSC for Ce0.9Zr0.1O2, which also exhibits highly porous and significantly rough surface characteristics. The surface potential observed from KPM studies varied between 30 and 80 mV, with Ce-rich compositions exhibiting the highest surface potential. Surface potential shows large changes after reduction or oxidation of the CZ film demonstrating the influence of Ce3+/Ce4+ on surface potential, which is also a key to catalytic activity for ceria-based catalysts. The surface potential measured from KPM and the OSC measured from MB vary linearly and they depend on the Ce3+/Ce4+ ratio. More and detailed studies are suggested to arrive at a correlation between the physical and chemical properties of the surfaces.

AB - Very recently two dimensional layers of boron atoms, so called borophene, have been successfully synthesized. It presents a metallic band structure, with a strong anisotropic character. Upon further hydrogen adsorption a new material is obtained, borophane; giving rise to a Dirac cone structure like the one in graphene. We have performed a first-principles study of the electronic and transport properties of borophene and borophane through the Landauer-Buttiker formalism. We find that borophene presents an electronic current two orders of magnitude larger than borophane. In addition we verified the direction dependence of the electronic current in two perpendicular directions, namely, Ix and Iy; where for both systems, we found a current ratio, eta = Ix/Iy, of around 2. Aiming to control such a current anisotropy, eta, we performed a study of its dependence with respect to an external strain. Where, by stretching the borophane sheet, eta increases by 11% for a bias voltage of 50 mV.

AB - Using the TiO2(110)-supported Pd7 cluster as a model catalyst, we have identified from density functional theory calculations that the dynamics of supported metal nanoparticles, particularly at the sub-nanometer scale, can be complex under reactive environments. Increasing the CO coverage can induce a structural transformation from Pd7-3D/TiO2(110) at low coverage to Pd7-2D/TiO2(110) at the saturation coverage wherein CO saturation-driven Pd7-2D/TiO2(110) structure displays superior CO oxidation activity at the interfacial sites, which are highly active for catalyzing O2 dissociation and CO oxidation via bifunctional synergy. PMID- 27711513 TI - 17O MAS NMR studies of oxo-based olefin metathesis catalysts: a critical assessment of signal enhancement methods. AB - The DFS enhancement method as applied to 17O MAS NMR was critically assessed, first on NaPO3, a simple binary glass system, and in a second step, on a series of catalysis-related organometallic molecules and materials. The robustness of DFS was investigated for the wide range of anisotropic parameters (quadrupolar coupling and chemical shift anisotropy) encountered in these samples. Emphasis has been put on the variation of signal enhancements with respect to the DFS final sweep frequency, pulse amplitude and pulse duration, while line shape distortion issues were also addressed. Finally, the robustness of DFS enhancement of the 17O MAS NMR signal is shown through its successful application to silica supported olefin metathesis catalysts. PMID- 27711514 TI - Growth patterns and structural motifs of cadmium clusters with up to 60 atoms: disordered or not? AB - Using two different approaches, the structures of Cdn clusters are optimized. At first, parameterized density-functional calculations using the DFTB method in combination with evolutionary algorithms provide one set of candidate structures. Second, earlier proposed structures based on the Gupta potential provide a second set. Subsequently, all structures of each set are re-optimized using parameter free density-functional calculations. It turned out that those based on the DFTB calculations in almost all cases were those of the lowest total energy. By analysing the structural properties as a function of cluster size information on growth patterns can be extracted. Thereby, the results show a certain preference that the atoms of the inner parts have surroundings as found in bulk hcp Cd. Furthermore, for larger size ranges, we could identify a specific growth pattern, implying that most of these clusters cannot be classified as being disordered. The results show also that the 4d electrons have only a weak influence on the properties of the clusters that, however, is so strong that a jellium-like model occasionally becomes inaccurate in describing the properties. In particular, the question at which size the clusters can be considered to be metallic becomes non trivial to answer. Further arguments based on a comparison of the HOMO-LUMO gaps with the Kubo gap, however, suggested the non-metallic properties in the studied size range. PMID- 27711515 TI - Large enhancement in photocurrent by Mn doping in CdSe/ZTO quantum dot sensitized solar cells. AB - We find a large enhancement in the efficiency of CdSe quantum dot sensitized solar cells by doping with manganese. In the presence of Mn impurities in relatively small concentrations (2.3%) the photoelectric current increases by up to 190%. The average photocurrent enhancement is about 160%. This effect cannot be explained by a light absorption mechanism because the experimental and theoretical absorption spectra demonstrate that there is no change in the absorption coefficient in the presence of the Mn impurities. To explain such a large increase in the injection current we propose a tunneling mechanism of electron injection from the quantum dot LUMO state to the Zn2SnO4 (ZTO) semiconductor photoanode. The calculated enhancement is approximately equal to 150% which is very close to the experimental average value of 160%. The relative discrepancy between the calculated and experimentally measured ratios of the IPCE currents is only 6.25%. For other mechanisms (such as electron trapping, etc.) the remaining 6.25% cannot explain the large change in the experimental IPCE. Thus we have indirectly proved that electron tunneling is the major mechanism of photocurrent enhancement. This work proposes a new approach for a significant improvement in the efficiency of quantum dot sensitized solar cells. PMID- 27711516 TI - Phosphine passivated gold clusters: how charge transfer affects electronic structure and stability. AB - A systematic evaluation of small phosphine ligand-protected gold clusters with six to nine gold atoms using density functional theory with dispersion correction has been performed in order to understand the major factors determining stability, including its size, shape, and charge dependence. We show that the charge per atom of the cluster is much more important for the interaction between the ligand shell and gold cluster than the system size. Thus, strong charge transfer effects determine the binding strength between the ligand shell and cluster. The clusters in this series are all non-spherical and exhibit large HOMO LUMO gaps (above 2.7 eV). Analysis of the delocalized nature of the electronic states at the centre of the clusters demonstrates the presence of nascent superatomic states. However the number of delocalized electrons in these systems is significantly influenced by the charge transfer from the phosphine ligands, contrary to the usual accounting rule for superatom complex systems. Thus, not only electron withdrawing but also charge transfer effects should be considered to influence the superatomic structure of charged ligand surrounded clusters. In consequence in the phosphine gold cluster series under consideration the systems Au7(PPh3)7+ and Au8(PPh3)82+ exhibit nearly fully filled S and P states and the HOMO-LUMO gap increases by 0.2 eV and 0.9 eV, respectively. The interpretation for the stability of the gold phosphine systems is in agreement with experimental results and demonstrates the importance of the superatomic concept. PMID- 27711517 TI - Wetting behavior of water on silicon carbide polar surfaces. AB - Technically important wide band-gap semiconductors such as GaN, AlN, ZnO and SiC are crystallized in polar structures. Taking SiC as an example, we investigate the effect of surface polarity on the wetting behavior by water using experiments and molecular dynamic simulations. It is found that the contact angle (CA) of deionized water on the carbon-face (C-face) is significantly larger than that on the silicon-face (Si-face) for both 6H-SiC and 4H-SiC, while the CA of tetrachloromethane is almost the same on these two faces. This finding clearly indicates that polar interactions between water and SiC induce such a large difference in the CA. Extensive molecular dynamics simulations suggest that a larger CA on the C-face than that on the Si-face is resulted from the different charge agglomeration on the two faces. These results will not only be helpful in improving the state of the art processes such as rinsing and wet etching in device fabrication, but also offer a reliable method to determine the polarity of SiC crystals quickly, simply, accurately and nondestructively, which is easily extendable for the measurement of other polar crystals. PMID- 27711518 TI - Fast and slow dynamics and the local structure of liquid and supercooled water next to a hydrophobic amino acid. AB - We study, through molecular dynamics simulations, the structure and orientational dynamics of water next to a blocked hydrophobic amino acid, valine (Val), above and below the freezing point of water. The structure and the orientational dynamics of waters with four water neighbors (4WN) and less than four water neighbors (L4WN) in the Val's coordination sphere are deconvoluted. We find that in spite of the excluded volume effects waters with L4WN have faster librational dynamics than bulk water, reminiscent of water at the liquid-vapor interface, and faster orientational dynamics than waters with 4WN, at every temperature. Furthermore, our results show that the pronounced decrease of the orientational retardation factor below ~255 K observed experimentally is mostly caused by the acceleration of the orientational dynamics of waters with L4WN, while waters with 4WN exhibit only moderate acceleration. The differences between the hydrogen-bond acceptor switching mechanism in the shell and the bulk are also analyzed, and no evidence of especially slow OH groups neither in the 4WN nor in the L4WN populations is found. Finally, we show that waters with 4WN have higher tetrahedrality than bulk water at every temperature although this difference decreases at both high and low temperatures. PMID- 27711519 TI - Theoretical calculation of the vibrational state dependent photodetachment spectra of X-H2O, X = F, Cl, Br. AB - Vibrational spectra of X-H2O (X = F, Cl, Br) were simulated using full dimensional vibrational calculations using quantum chemistry potential energy surfaces. Furthermore, utilizing the reflection approximation, we simulated the photodetachment spectra obtained from different vibrational excited states. From these spectra, we can observe changes in the hydrogen bond interaction between the anion and the neutral XH2O system. Notably, for F-H2O, the excitation of the ionic hydrogen bonded (IHB) OH stretching vibration generates a large tail on the low energy side of the photodetachment spectra compared to the detachment from the zero-point vibration state. This shows that the IHB OH stretching vibration of F-H2O causes charge delocalization from F- to the oxygen atom in H2O, and that the photodetachment from FHOH- occurs at lower energies. PMID- 27711520 TI - The possible formation of a magnetic FeS2 phase in the two-dimensional MoS2 matrix. AB - The possibility of a FeS2 phase formation in the 2D MoS2 structure was investigated by an ab initio DFT approach. Various concentrations of FeS2 in MoS2 have been analyzed, and it is shown that the energy favorable structures of the Mo1-xFexS2 composition are in-plane hybrid phases, FeS2 and MoS2 domains. After increasing the Fe/Mo concentration ratio up to 0.68, a complete transformation of the whole structure is predicted. We have found that the introduction of only a small amount of Fe atoms leads to a change in the electronic and magnetic properties of the film. An increase of the FeS2 nucleus size leads to the nearly monotonous increase of the magnetic moment governed by the exponential law.

AB - Ab initio calculations predict that pyridine (Py) can act as a photo-catalyst to split water by the absorption of a UV photon following the reaction Py-H2O + hnu > PyH + OH. To test this prediction, we performed two types of experiments: in the first, we characterize the electronic spectroscopy of the PyH radical in the gas phase. In the second, we evidence the reaction through the UV excitation of molecular Py-(H2O)n clusters obtained in a supersonic expansion and monitoring the PyH reaction product. The results show unambiguously that PyH is produced, and thus that water is split using pyridine as a photo-catalyst.

AB - Density-functional theory and symmetry-adapted perturbation theory calculations on complexes of the enantiomers of CHFClBr with the most stable isomer of C82-3 fullerene show that despite the guests being too large for the host cage, they are nevertheless stabilized by electrostatic interactions. The complexation leads to considerable strain on the cage and the guests accompanied by compression of the bonds of the guest molecule, resulting in considerable complexation-induced changes in the infrared (IR), vibrational circular dichroism (VCD), nuclear magnetic resonance (NMR), and UV-vis spectra. The effect of chiral recognition is pronounced only for the 19F signal in the NMR spectra and in a sign reversal of the rotational strength of the nuCH stretching vibration of S-CHFClBr@C82-3 in the VCD spectrum as compared to that of the free guest, making the sign of this band for the C82 complexes with the S- and R-guest enantiomers the same. This is a surprising result since vibrational circular dichroism is considered a reliable method for determining the absolute chirality of small molecules and for establishing dominant conformations in biopolymers.

AB - The thermally induced Spin-CrossOver (SCO) undergone by the mononuclear iron(ii) complex [Fe(PM-AzA)2(NCS)2] (PM = N-2'-pyridylmethylene, AzA = 4 (phenylazo)aniline) is fully pictured by a quasi-continuous structural determination all along the spin-state modification within the sample. This large scale multi-temperature Single-Crystal X-Ray Diffraction (SCXRD) investigation leads to making structural movies. The latter reveal or confirm some features of the SCO that are subsequently validated by the same systematic investigation performed on a zinc isostructural analogue complex. Notably, the continuous views of the temperature dependencies of the unit-cell parameters, the dilatation tensors, the metal coordination sphere geometry and the intermolecular distances confirm a few of the structure-property relationships already known for SCO materials. In parallel, the examination of the temperature dependencies of the atomic coordinates and the atomic displacement parameters reveals unexpected behaviours in this gradual SCO material such as antagonistic atomic movements due to the single SCO and the pure thermal effects.

AB - In this study, a series of random copolymer poly(acrylic acid-co-styrene) (P(AA co-St)) and block copolymer poly(acrylic acid)-b-polystyrene (PAA-b-PSt) with similar chemical composition but different chain microstructure were synthesized. The self-assembly behavior of random and block copolymers in selective solvent was investigated, and the structural evaluation of random and block copolymers micelles was carried out by transmission electron microscopy (TEM), dynamic light scattering (DLS) measurement, and X-ray photoelectron spectroscopy (XPS). Moreover, together with experimental characterization, the theoretical method dissipative particle dynamics (DPD) approach was applied to investigate the morphological structures of micelles composed from random and block copolymers. Results revealed that the structure of polymeric micelles is significantly affected by the distribution sequence of hydrophilic and hydrophobic monomers in copolymer chains. Furthermore, polymeric micelles based on P(AA-co-St) and PAA-b PSt with about 50 mol% hydrophilic composition were chosen as the model to investigate the influence of micellar structure on emulsifying performance. For PAA-b-PSt micelles (B48), stable water-in-oil (w/o) emulsions could only obtained when the pH values were lower than 5. As a comparison, the P(AA-co-St) micelles (R49) had an excellent emulsification performance at 4-10 pH, and the pH-induced phase inversion derived from obtained emulsions observed at pH higher than 6. Preliminary results confirm that the micellar structure controlled by chain microstructure plays an important role in the interface behavior of polymer micelles. Compared with PAA-b-PSt micelles, P(AA-co-St) micelles have better interfacial performance and are more tailorable and controllable; thus they can be used as a model for further study of polymeric particulate emulsifiers. This paper provides new insight into the principles governing extremely high emulsifying efficiency of polymeric particulate emulsifiers and pH-responsive properties of the formed emulsions.

AB - We interpreted the mechanisms of energy harvesting and conversion for intrinsic upconverted mechano-persistent luminescence in CaZnOS through a native point defects study. We found that vacancy defects such as Zn and O vacancies, as well as Schottky pair defects, act as energy harvesting centers; they are very readily formed and very active. They are found to be extra deep electron or hole trap levels near the valence or conduction band edges, respectively. This leads to a coupling and exchange effect to continuously collect and transport host charges along a path via localized states to deep recombination levels. The initiating energy barrier is small and can be overcome by ambient thermal stimulation or quantum tunneling. Native activators such as V, V, and V function as energy conversion centers to transfer energy into photon emissions. This gives a solid theoretical reference for developing upconverted mechano-persistent luminescence. PMID- 27711527 TI - Determination of the local structure of CsBi4-xPbxTe6 (x = 0, 0.5) by X-ray absorption spectroscopy. AB - We have studied the local structure and valence electronic unoccupied states of thermoelectric CsBi4Te6 and superconducting CsBi3.5Pb0.5Te6 (Tc ~ 3 K) by extended X-ray absorption fine structure (EXAFS) and X-ray absorption near edge structure (XANES) measurements. The Bi-L3 edge EXAFS reveals wide Bi-Te distance distribution for both compounds indicating complex atomic arrangements in the studied system. The mean square relative displacements (MSRDs) of the Bi-Te bond distances appear largely increased in Pb substituted system due to larger overall local disorder, however, one of the Bi-Te bonds shows a reduced disorder. On the other hand, the Bi-L3 edge XANES is hardly affected by Pb substitution while the Te-L1 edge XANES reveals increased density of unoccupied Te 5p states. This suggests that the carriers introduced by the Pb substitution in CsBi4-xPbxTe6 preferentially goes on Te sites. Similarly, the Cs-L3 edge XANES also shows small changes due to Pb-substitution and reduced local disorder indicated by the reduced width of the Cs-L3 edge white line. We have also shown that the X-ray photoemission spectroscopy (XPS) measurements on various electronic core levels are in a qualitative agreement with the XANES results. These findings are consistent with carrier doping and a reduced disorder in one direction to be likely factors to drive the thermoelectric CsBi4Te6 into a bulk superconductor by Pb-substitution in CsBi4-xPbxTe6.

AB - Layered lithium transition metal oxides are one of the most important types of cathode materials in lithium-ion batteries (LIBs) that possess high capacity and relatively low cost. Nevertheless, these layered cathode materials suffer structural changes during electrochemical cycling that could adversely affect the battery performance. Clear explanations of the cathode degradation process and its initiation, however, are still under debate and not yet fully understood. We herein systematically investigate the chemical evolution and structural transformation of the LiNixMnyCo1-x-yO2 (NMC) cathode material in order to understand the battery performance deterioration driven by the cathode degradation upon cycling. Using high-resolution electron energy loss spectroscopy (HR-EELS) we clarify the role of transition metals in the charge compensation mechanism, particularly the controversial Ni2+ (active) and Co3+ (stable) ions, at different states-of-charge (SOC) under 4.6 V operation voltage. The cathode evolution is studied in detail from the first-charge to long-term cycling using complementary diagnostic tools. With the bulk sensitive 7Li nuclear magnetic resonance (NMR) measurements, we show that the local ordering of transition metal and Li layers (R3[combining macron]m structure) is well retained in the bulk material upon cycling. In complement to the bulk measurements, we locally probe the valence state distribution of cations and the surface structure of NMC particles using EELS and scanning transmission electron microscopy (STEM). The results reveal that the surface evolution of NMC is initiated in the first charging step with a surface reduction layer formed at the particle surface. The NMC surface undergoes phase transformation from the layered structure to a poor electronic and ionic conducting transition-metal oxide rock-salt phase (R3[combining macron]m -> Fm3[combining macron]m), accompanied by irreversible lithium and oxygen loss. In addition to the electrochemical cycling effect, electrolyte exposure also shows non-negligible influence on cathode surface degradation. These chemical and structural changes of the NMC cathode could contribute to the first-cycle coulombic inefficiency, restrict the charge transfer characteristics and ultimately impact the cell capacity.

AB - In this publication we conduct calculations on a newly synthesised red-shifted emitter of luciferin in order to understand what are the main contributions to the colour-shifting emission. Indeed the bioluminescent system, especially from fireflies, is one of the main resources for medical imaging but its efficiency greatly depends on the wavelength of the emission. We performed classical molecular dynamics followed by quantum mechanics/molecular mechanics (QM/MM) calculations, with either density functional theory or multiconfigurational reference second-order perturbation theory on different emitters to obtain bioluminescence emission. We analysed the calculations and investigated the effects which play a non-negligible role in the emission, like the effect of the surroundings or the effect of the conformation of the emitter. Finally, in the absence of crystallographic structures, we proposed the most likely conformation for the emitter in the bioluminescence process.

AB - Infrared absorption spectra of glycine and glycine-water aggregates embedded in superfluid helium nanodroplets were recorded in the frequency range 1000-1450 cm 1. For glycine monomer, absorption bands were observed at 1106 cm-1, 1134 cm-1, and 1389 cm-1. These bands were assigned to the C-OH stretch mode of the glycine conformers I, III and II, respectively. For glycine-water aggregates, we observed two bands at 1209 cm-1 and 1410 cm-1 which we assign to distinct conformers of glycine-H2O. In all cases, the water is found to preferentially bind to the carboxyl group of the glycine. PMID- 27711532 TI - EPR characterization of Mn(ii) complexes for distance determination with pulsed dipolar spectroscopy. AB - The four Mn(ii) complexes Mn-DOTA, Mn-TAHA, Mn-PyMTA, and Mn-NO3Py were characterized by electron paramagnetic resonance (EPR), electron-nuclear double resonance (ENDOR), and relaxation measurements, to predict their relative performance in the EPR pulse dipolar spectroscopy (PDS) experiments. High spin density localization on the metal ions was proven by ENDOR on 1H, D, 14N, and 55Mn nuclei. The transverse relaxation of the Mn(ii) complexes appears to be slow enough for PDS-based spin-spin distance determination. Rather advantageous ratios of T1/Tm were measured allowing for good relaxation induced dipolar modulation enhancement (RIDME) performance and, in general, fast shot repetitions in any PDS experiment. Relaxation properties of the Mn(ii) complexes correlate with the strengths of their zero field splitting (ZFS). Further, a comparison of Mn(ii) DOTA and Gd(iii)-DOTA based spin labels is presented. The RIDME technique to measure nanometer-range Mn(ii)-Mn(ii) distances in biomolecules is discussed as an alternative to the well-known DEER technique that often appears challenging in cases of metal-metal distance measurements. The use of a modified kernel function that includes dipolar harmonic overtones allows model-free computation of the Mn(ii)-Mn(ii) distance distributions. Mn(ii)-Mn(ii) distances are computed from RIDME data of Mn-rulers consisting of two Mn-PyMTA complexes connected by a rodlike spacer of defined length. Level crossing effects seem to have only a weak influence on the distance distributions computed from this set of Mn(ii)-Mn(ii) RIDME data. PMID- 27711535 TI - Temperature dependence of the reaction of anti-CH3CHOO with water vapor. AB - The kinetics of the reaction of anti-CH3CHOO with water vapor were investigated using transient UV absorption spectroscopy at temperatures from 288 to 328 K and 500 Torr. We found that both the water monomer and the water dimer react with anti-CH3CHOO. The rate coefficients of the reaction of the water monomer and dimer with anti-CH3CHOO at 298 K were determined to be (1.31 +/- 0.26) * 10-14 cm3 s-1 and (4.40 +/- 0.29) * 10-11 cm3 s-1, respectively. Furthermore, for the water dimer reaction, we observed very large negative temperature dependence with an activation energy of -12.17 +/- 0.66 kcal mol-1. On the other hand, the monomer reaction showed minimal temperature dependence with nearly zero activation energy. At atmospherically relevant humidity, in opposition to previous experiments conducted for CH2OO in which water dimer reaction predominates at room temperature, for anti-CH3CHOO, the water monomer reaction can contribute significantly (~30% of the reaction with water vapor at relative humidity RH = 40% and 298 K). These results show that substitution of an alkyl group can greatly affect the reaction of Criegee intermediates with water vapor, especially changing the contributions of water monomer and dimer reactions. PMID- 27711536 TI - Post-perovskite CaIrO3: a conventional Slater type antiferromagnetic insulator. AB - To resolve the controversy of whether or not the origin of an electronic gap in antiferromagnetic post-perovskite (pPv) CaIrO3 is due to Coulomb repulsion or spin-orbit coupling, and/or both, we have performed comprehensive full potential density functional theory based calculations. A rather consistent electronic structure, which explains the origin and magnitude of the electronic gap, inter band d-d transition energies, high thermopower and large magneto-crystalline anisotropy, is obtained with the use of a modified Becke-Johnson (mBJ) exchange potential. Fundamentally, mBJ calculations correctly capture the strong interplay of the crystal field and long range antiferromagnetic ordering of Ir spins as the mechanism that drives pPv-CaIrO3 to an insulating state. Based on our findings, we propose that pPv-CaIrO3 is a conventional Slater type antiferromagnetic insulator.

AB - An ab initio molecular dynamics investigation is carried out on various water borne Se(iv) species, H2SeO3, HSeO3- and SeO32-, in aqueous environment. Consistent with the reported acid dissociation constants, in neutral solution H2SeO3 exchanges protons with the surrounding water molecules establishing a dynamic equilibrium with HSeO3-. The SeO32- species is found to be stable only in basic environment, which is emulated in the present simulation through introducing a hydroxide ion, OH-, in the system. The hydration structure, hydrogen bonding and spectroscopic signatures of the species are comprehensively analyzed. The influence of the solute's hydration structure on the structural and dynamic response of the solvent is discussed. The correlation between the strength as well as the number of hydrogen bonds accepted by the solute on its vibrational properties are analyzed. PMID- 27711538 TI - Concerted nitrogen inversion and hydrogen bonding to Glu451 are responsible for protein-controlled suppression of the reverse reaction in human DPP III. AB - Human dipeptidyl-peptidase III (h.DPP III) is a zinc-exopeptidase that hydrolyses dipeptides from the N-terminus of its substrates. Its mechanism of action was assumed to be similar to that of thermolysin, but was never thoroughly investigated. This study presents the first insight into the reaction mechanism of h.DPP III, determined on the model and real (hydrated enzyme with Leu enkephalin bound in the active site) systems. The Glu451-assisted water addition on amide carbon atoms and nitrogen inversion (i.e. change of pyramidalization on the leaving nitrogen) are shown to be the rate-determining steps with the activation energies in a good agreement with the experimental results for the Leu enkephalin hydrolysis. The energy barrier for nucleophilic attack is about 28 kJ mol-1, while barriers for the N-inversion differ as a consequence of the number of hydrogen bonds that have to be changed, which is smaller in the model active site than in the solvated enzyme. Although precisely defined geometry of the enzyme binding site puts an additional restraint on the hydrogen bonding interactions, at the same time it stimulates the forward reaction towards the final hydrolytic product. Namely, different from the model, the N-inversion is in a concerted fashion followed by favourable hydrogen bonding with Glu451 that immediately "locks" the system into the configuration where reversion to the enzyme-substrate complex is hardly achievable. Therefore we propose that the functional significance of DPP III is dual: to lower the energy barrier of the peptide hydrolysis and to suppress the reverse reaction. PMID- 27711539 TI - Computational investigation into the gas-phase ozonolysis of the conjugated monoterpene alpha-phellandrene. AB - Reaction with ozone is a major atmospheric sink for alpha-phellandrene, a monoterpene found in both indoor and outdoor environments, however experimental literature concerning the reaction is scarce. In this study, high-level G4(MP2) quantum chemical calculations are used to theoretically characterise the reaction of ozone with both double bonds in alpha-phellandrene for the first time. Results show that addition of ozone to the least substituted double bond in the conjugated system is preferred. Following addition, thermal and chemically activated unimolecular reactions, including the so-called hydroperoxide and ester or 'hot' acid channels, and internal cyclisation reactions, are characterised to major first generation products. Conjugation present in alpha-phellandrene allows two favourable Criegee intermediate reaction pathways to proceed that have not previously been considered in the literature; namely a 1,6-allyl resonance stabilised hydrogen shift and intramolecular dioxirane isomerisation to an epoxide. These channels are expected to play an important role alongside conventional routes in the ozonolysis of a-phellandrene. Computational characterisation of the potential energy surface thus provides insight into this previously unstudied system, and will aid future mechanism development and experimental interpretation involving alpha-phellandrene and structurally similar species, to which the results are expected to extend. PMID- 27711540 TI - Systematic design and application of unimolecular star-like block copolymer micelles: a coarse-grained simulation study. AB - Unimolecular polymeric micelles have several features, such as thermodynamic stability, small particle size, biocompatibility, and the ability to internalize hydrophobic molecules. These micelles have recently attracted significant attention in various applications, such as nano-reactors, catalysis, and drug delivery. However, few attempts have explored the formation mechanisms and conditions of unimolecular micelles due to limited experimental techniques. In this study, a unimolecular micelle system formed from beta-cyclodextrin-graft {poly(lactide)-block-poly(2-(dimethylamino) ethyl multimethacrylate)-block poly[oligo (2-ethyl-2-oxazoline) methacrylate]} beta-CD-g-(PLA-b-PDMAEMA-b PEtOxMA) star-like block copolymers in aqueous media was investigated by dissipative particle dynamics (DPD) to explore the formation process of unimolecular micelles. The simulation results showed that using longer hydrophobic or pH-sensitive chains, shorter hydrophilic backbones, smaller hydrophilic side chain grafting density, and fewer polymer arms resulted in micellar aggregation. Furthermore, this unimolecular polymeric micelle could be used for encapsulating gold nanoparticles, whose mesoscopic structure was also explored. The gold nanoparticles tended to distribute in the middle layer formed by PDMAEMA, and the unimolecular micelles were capable of impeding gold nanoparticle aggregation. This study could help understand the formation mechanism of unimolecular micelles formed from star-like block copolymers in dilute solutions and offer a theoretical guide to the design and preparation of promising unimolecular polymeric micelles with targeting properties. PMID- 27711541 TI - Electron transfer across the germanium-polyelectrolyte-gold nanoparticle interface: convenient detection and applications in sensing. AB - Germanium-polyelectrolyte-gold nanoparticle composites were prepared and characterized using FTIR-ATR spectroscopy and scanning electron microscopy. The germanium (Ge) element served as an internal reflection element and the buildup of the layered system was followed in situ. A positively charged polyelectrolyte, poly (allylamine hydrochloride) (PAH) adsorbs spontaneously on negatively charged Ge. Citrate-stabilized gold nanoparticles can then be adsorbed onto the PAH layer. Upon illumination of the device with visible light a prominent absorption over the entire mid infrared region is observed which is due to intervalence band transitions in Ge. The strong infrared signals are evidence for holes in the valence band of the Ge semiconductor, which arise due to electron transfer to the gold nanoparticles (GNPs). The electron transfer, as evidenced by the holes in Ge, is affected by the nature of the gap between the Ge semiconductor and the GNPs. Increasing the gap by adsorbing polyelectrolyte multilayers hinders the electron transfer. Also, heating and vacuum have a pronounced effect. The device is proposed as a sensor, where the sensing event is transduced into an optical signal in the infrared region, as demonstrated for a thiol molecule. The thiol has a large affinity for gold, and therefore affects the germanium-gold nanoparticle gap. This reduces the electron transfer, and therefore the absorption in the infrared region upon illumination with visible light. Removal of the thiol from the solution leads to the recovery of the signal. PMID- 27711542 TI - Bottom-up excited state dynamics of two cinnamate-based sunscreen filter molecules. AB - Methyl-E-4-methoxycinnamate (E-MMC) is a model chromophore of the commonly used commercial sunscreen agent, 2-ethylhexyl-E-4-methoxycinnamate (E-EHMC). In an effort to garner a molecular-level understanding of the photoprotection mechanisms in operation with E-EHMC, we have used time-resolved pump-probe spectroscopy to explore E-MMC's and E-EHMC's excited state dynamics upon UV-B photoexcitation to the S1 (11pipi*) state in both the gas- and solution-phase. In the gas-phase, our studies suggest that the excited state dynamics are driven by non-radiative decay from the 11pipi* to the S3 (11npi*) state, followed by de excitation from the 11npi* to the ground electronic state (S0). Using both a non polar-aprotic solvent, cyclohexane, and a polar-protic solvent, methanol, we investigated E-MMC and E-EHMC's photochemistry in a more realistic, 'closer-to shelf' environment. A stark change to the excited state dynamics in the gas-phase is observed in the solution-phase suggesting that the dynamics are now driven by efficient E/Z isomerisation from the initially photoexcited 11pipi* state to S0. PMID- 27711543 TI - Exploring the substrate specificity and catalytic mechanism of imidazolonepropionase (HutI) from Bacillus subtilis. AB - Imidazolonepropionase (HutI, EC 3.5.2.7) catalyzes the hydrolytic cleavage of carbon-nitrogen bond in 4-imidazolone-5-propionic acid (IPA) to yield l formiminoglutamic acid, which is the third step in the universal histidine degradation pathway. In this article, using a combined quantum mechanics and molecular mechanics (QM/MM) approach, the specificity and catalytic mechanism of HutI from Bacillus subtilis have been explored by considering the four isomers of (S)- and (R)-enantiomers of IPA (SIPA-1, SIPA-2, RIPA-1 and RIPA-2). Our calculations reveal that the activation of hydrolytic water (a zinc-bound water) is performed by residue E252 via a "bridging" water molecule, which occurs before binding of the substrate. After the substrate binding, this activation channel is blocked by the substrate, and the other two residues (D324 and H272) cannot act as the general base to activate the hydrolytic water. For the two (S)-enantiomers of IPA, HutI can specifically convert one isomer of (S)-enantiomer (SIPA-1) to l formiminoglutamic acid with an energy barrier of 16.6 kcal mol-1. The conversion of another (S)-enantiomer (SIPA-2) corresponds to the energy barrier of 21.9 kcal mol-1. However, for the two isomers of (R)-enantiomer, RIPA-1 corresponds to a higher energy barrier (21.8 kcal mol-1), and RIPA-2 is associated with a weak binding in the active site compared to SIPA-2. Thus, on the basis of our calculations, SIPA-1 is suggested to be the most favorable substrate for HutI, whereas the hydrolytic cleavage of SIPA-2 may require a preliminary isomerization to SIPA-1. PMID- 27711545 TI - Adsorption in zeolites using mechanically embedded ONIOM clusters. AB - We have explored mechanically embedded three-layer QM/QM/MM ONIOM models for computational studies of binding in Al-substituted zeolites. In all the models considered, the high-level-theory layer consists of the adsorbate molecule and of the framework atoms within the first two coordination spheres of the Al atom and is treated at the M06-2X/6-311G(2df,p) level. For simplicity, flexibility and routine applicability, the outer, low-level-theory layer is treated with the UFF. We have modelled the intermediate-level layer quantum mechanically and investigated the performance of HF theory and of three DFT functionals, B3LYP, M06-2X and omegaB97x-D, for different layer sizes and various basis sets, with and without BSSE corrections. We have studied the binding of sixteen probe molecules in H-MFI and compared the computed adsorption enthalpies with published experimental data. We have demonstrated that HF and B3LYP are inadequate for the description of the interactions between the probe molecules and the framework surrounding the metal site of the zeolite on account of their inability to capture dispersion forces. Both M06-2X and omegaB97x-D on average converge within ca. 10% of the experimental values. We have further demonstrated transferability of the approach by computing the binding enthalpies of n-alkanes (C1-C8) in H MFI, H-BEA and H-FAU, with very satisfactory agreement with experiment. The computed entropies of adsorption of n-alkanes in H-MFI are also found to be in good agreement with experimental data. Finally, we compare with published adsorption energies calculated by periodic-DFT for n-C3 to n-C6 alkanes, water and methanol in H-ZSM-5 and find very good agreement. PMID- 27711546 TI - Morphological modulation of graphene-mediated hybridization in plasmonic systems. AB - We investigated the plasmonic response of a 2-dimensional ordered array of closely spaced (few-nm apart) Au nanoparticles covered by a large-area single layer graphene sheet. The array consisted of coherently aligned nanoparticle chains, endowed with a characteristic uniaxial anisotropy. The joint effect of such a morphology and of the very small particle size and spacing led to a corresponding uniaxial wrinkling of graphene in the absence of detectable strain. The deposition of graphene redshifted the Au plasmon-resonance, strongly increased the optical absorption of the array and, most importantly, induced a marked optical anisotropy in the plasmonic response, absent in the pristine nanoparticle array. The experimental observations are accounted for by invoking a graphene-mediated resistive coupling between the Au nanoparticles, where the optical anisotropy arises from the wrinkling-induced anisotropic electron mobility in graphene at optical frequencies. PMID- 27711547 TI - A computational study of the competing reaction mechanisms of the photo-catalytic reduction of CO2 on anatase(101). AB - We perform a computational study of three different reaction mechanisms for the photo-catalytic reduction of CO2 on the TiO2 anatase(101) surface known as (i) the carbene, (ii) the formaldehyde and (iii) the glyoxal pathways. We define a set of approximations that allows testing a number of mechanistic hypotheses and design experiments to validate them. We find that the energetically most favourable reaction mechanism among those proposed in the literature is the formaldehyde path, and the rate-limiting step is likely to be the formation of CH3 radicals from dissociation of CH3OH. We show that an intermediate that supports this mechanism is OCH2OH. We also find that formaldehyde would be an energetically favorable intermediate forming from CO and HCO, intermediates that are proposed in the early stage of the carbene and glyoxal pathways respectively. Some possible variants of mechanisms and methods to ease the formation of CH3 radicals are also discussed. PMID- 27711548 TI - Superelastic stress-strain behavior in ferrogels with different types of magneto elastic coupling. AB - Colloidal magnetic particles embedded in an elastic polymer matrix constitute a smart material called a ferrogel. It responds to an applied external magnetic field by changes in elastic properties, which can be exploited for various applications such as dampers, vibration absorbers, or actuators. Under appropriate conditions, the stress-strain behavior of a ferrogel can display a fascinating feature: superelasticity, the capability to reversibly deform by a huge amount while barely altering the applied load. In previous work, using numerical simulations, we investigated this behavior assuming that the magnetic moments carried by the embedded particles can freely reorient to minimize their magnetic interaction energy. Here, we extend the analysis to ferrogels where restoring torques by the surrounding matrix hinder rotations towards a magnetically favored configuration. For example, the particles can be chemically cross-linked into the polymer matrix and the magnetic moments can be fixed to the particle axes. We demonstrate that these systems still feature a superelastic regime. As before, the nonlinear stress-strain behavior can be reversibly tailored during operation by external magnetic fields. Yet, the different coupling of the magnetic moments causes different types of response to external stimuli. For instance, an external magnetic field applied parallel to the stretching axis hardly affects the superelastic regime but stiffens the system beyond it. Other smart materials featuring superelasticity, e.g. metallic shape memory alloys, have already found widespread applications. Our soft polymer systems offer many additional advantages such as a typically higher deformability and enhanced biocompatibility combined with high tunability.

AB - In this paper we apply the computational analysis recently proposed by our group to characterize the solvation properties of a native protein in aqueous solution, and to four model aqueous solutions of globular proteins in their unfolded states thus characterizing the protein unfolded state hydration shell and quantitatively evaluating the protein unfolded state partial molar volumes. Moreover, by using both the native and unfolded protein partial molar volumes, we obtain the corresponding variations (unfolding partial molar volumes) to be compared with the available experimental estimates. We also reconstruct the temperature and pressure dependence of the unfolding partial molar volume of Myoglobin dissecting the structural and hydration effects involved in the process.

AB - The effects of external inhomogenous (gradient) magnetic fields on the movement of the rare-earth ions: Dy3+, Gd3+ and Y3+, in initially homogeneous aqueous solutions have been investigated. Differences in the migration of rare-earth ions in gradient magnetic fields were observed, depending on the magnetic character of the ions: paramagnetic ions of Dy3+ and Gd3+ move towards regions of the sample where the magnetic field gradient is the strongest, while diamagnetic ions of Y3+ move in the opposite direction. It has been showed that the low magnetic field gradients, such the ones generated by permanent magnets, are sufficient to observe the magnetomigration effects of the ions in solution. The present work clearly establishes the behavior of magnetically different ions in initially homogeneous aqueous solutions exposed to magnetic field gradients. To this avail, a methodology for measuring the local concentration differences of metal ions in liquid samples was developed.

AB - While halogenation of graphene presents a fascinating avenue to the construction of a chemically and physically diverse class of systems, their application in photovoltaics has been hindered by often prohibitively large optical gaps. Herein we study the effects of partial bromination and chlorination on the structure and optoelectronic properties of both graphane and fluorographene. We find brominated and chlorinated fluorographene derivatives to be as stable as graphane with a detailed investigation of the systems band structure revealing significant 1D localization of the charge carriers as well as strongly electron-hole asymmetric effective masses. Lastly using G0W0 and BSE, we investigate the optical adsorption spectra of the aforementioned materials whose first adsorption peak is shown to lie close to the optimal peak position for photovoltaic applications (~1.5 eV).

AB - The conformational preferences of a series of capped peptides containing the helicogenic amino acid aminoisobutyric acid (Aib) (Z-Aib-OH, Z-(Aib)2-OMe, and Z (Aib)4-OMe) are studied in the gas phase under expansion-cooled conditions. Aib oligomers are known to form 310-helical secondary structures in solution and in the solid phase. However, in the gas phase, accumulation of a macrodipole as the helix grows could inhibit helix stabilization. Implementing single-conformation IR spectroscopy in the NH stretch region, Z-Aib-OH and Z-(Aib)2-OMe are both observed to have minor conformations that exhibit dihedral angles consistent with the 310-helical portion of the Ramachandran map (phi, psi = -57 degrees , -30 degrees ), even though they lack sufficient backbone length to form 10-membered rings which are a hallmark of the developed 310-helix. For Z-(Aib)4-OMe three conformers are observed in the gas phase. Single-conformation infrared spectroscopy in both the NH stretch (Amide A) and C[double bond, length as m dash]O stretch (Amide I) regions identifies the main conformer as an incipient 310-helix, having two free NH groups and two C10 H-bonded NH groups, labeled an F F-10-10 structure, with a calculated dipole moment of 13.7 D. A second minor conformer has an infrared spectrum characteristic of an F-F-10-7 structure in which the third and fourth Aib residues have phi, psi = 75 degrees , -74 degrees and -52 degrees , 143 degrees , Ramachandran angles which fall outside of the typical range for 310-helices, and a dipole moment that shrinks to 5.4 D. These results show Aib to be a 310-helix former in the gas phase at the earliest stages of oligomer growth.

AB - During nitriding of nanocrystalline iron and reduction of iron nitrides with NH3/H2 mixtures, at the stationary states a hysteresis phenomenon is observed where two phases coexist, according to the extended phase rule of Gibbs due to the presence of an additional degree of freedom associated with the size of the nanocrystallites. Nanocrystallites transform from the biggest ones to the smallest due to differences in energy demand.

AB - Dichlorophosphanyl isocyanate, Cl2PNCO, was synthesized and characterized by IR, Raman and 31P NMR spectroscopy. The conformational properties and molecular structures were studied by using gas electron diffraction (GED), X-ray crystallography and quantum-chemical calculations. Extensive DFT and ab initio calculations show that the potential energy surface of Cl2PNCO upon rotating the P-N bond is rather flat; three conformers, namely syn, anti and gauche between the NCO group and the bisector of the ClPCl angle, were theoretically predicted. Experimentally, only one conformer was indicated by gas-phase IR spectroscopy and the preference for a gauche conformation in both gas phase and solid state was unambiguously ascertained by gas electron diffraction and X-ray crystallographic data. In the solid state, the Cl2PNCO molecules adopt a gauche conformation with two distinct dihedral angles Cl-P-N-C of -121.3(2) and 137.4(2) degrees and form polymeric chains through weak intermolecular CO contacts. Additionally, the dynamic character of the position of the isocyanate group of Cl2PNCO was examined in the gas phase.

AB - Based on density functional theory, we have systematically studied the crystal and electronic structures, and the diffusion mechanism of the NASICON-type solid electrolyte Na3Zr2Si2PO12. Four possible elementary processes are addressed: three inner-chain and one inter-chain processes. In inner-chain processes, Na tends to move inside the Na diffusion chain, while Na moves across the Na diffusion chain in the inter-chain process. The activation energies for the inner chain and inter-chain processes are 230 meV and 260 meV, respectively. By combining possible elementary processes, three preferable pathways along a, b, and c directions are found.

AB - Combining in vacuo deposition of ultrathin ionic liquid (UTIL) films with angle resolved X-ray photoelectron spectroscopy (ARXPS), we demonstrate that by deposition of submonolayer amounts of Pd onto Au(111) the initial growth mode of the ionic liquid (IL) 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([C2C1Im][OTf]) can be switched from three-dimensional (3D) to two-dimensional (2D) growth, that is, from non-wetting to wetting. On clean Au(111), pronounced 3D growth occurs on top of an initially formed 2D wetting layer with cations and anions next to each other in a checkerboard arrangement. After pre- or postdeposition of only 0.7 ML Pd, two-dimensional layer-by-layer growth is found, which is attributed to strong attractive interactions between [C2C1Im][OTf] and surface Pd. For Pd post deposition onto the IL, the ARXPS data revealed particularly strong interactions between the dialkylimidazolium cation and Pd atoms, which considerably reduce the regular surface alloying of Pd with the Au substrate stabilizing Pd at the metal surface. In the context of heterogeneous catalysis using the SCILL (solid catalyst coated with ionic liquid layer) concept, these results directly provide a possible explanation on the molecular level for the beneficial influence of the IL layer in case of heterogeneous metal alloy catalysts. PMID- 27711557 TI - Theoretical characterization of the conformational features of unnatural oligonucleotides containing a six nucleotide genetic alphabet. AB - The addition of the unnatural P:Z base pair to the four naturally occurring DNA bases expands the genetic alphabet and yields an artificially expanded genetic information system (AEGIS). Herein, the structural feature of oligonucleotides containing a novel unnatural P:Z base pair is characterized using both molecular dynamics and quantum chemistry. The results show that the incorporation of the novel artificial base pair (P:Z) preserves the global conformational feature of duplex DNA except for some local structures. The Z-nitro group imparts new properties to the groove width, which widens the major groove. The unnatural oligonucleotides containing mismatched base pairs exhibit low stability. This ensures efficient and high-fidelity replication. In general, the incorporation of the P:Z pair strengthens the stability of the corresponding DNA duplex. The calculated results also show that the thermostability originates from both hydrogen interaction and stacking interaction. The Z-nitro group plays an important role in enhancing the stability of the H-bonds and stacking strength of the P:Z pair. Overall, the present results provide theoretical insights in the exploration of artificially expanded genetic information systems. PMID- 27711558 TI - Molecular origin of photoluminescence of carbon dots: aggregation-induced orange red emission. AB - The molecular origin of the photoluminescence of carbon dots (CDs) is not known. This restricts the design of CDs with desired optical properties. We have synthesized CDs starting from carbohydrates by employing a simple synthesis method. We were able to demonstrate that the CDs are composed of aggregated hydroxymethylfurfural (HMF) derivatives. The optical properties of these CDs are quite unique. These CDs exhibit an excitation-independent PL emission maximum in the orange-red region (lambda ~ 590 nm). These CDs also exhibit excitation as well as monitoring wavelength-independent single exponential PL decay. These observations indicate that only one type of chromophore (HMF derivative) is present within the CDs. Several HMF derivatives are aggregated within the CDs; therefore, the aggregated structure cause a large Stokes shift (~150 nm). By several control experiments, we showed that the same aggregated chromophore unit (HMF derivative), and not the individual fluorophores, is the fluorescing unit. The emission maximum and the single exponential PL lifetime are independent of the polarity of the medium. The existence of a low-lying trap state could be reduced quite significantly. A model has been proposed to explain the interesting steady state and dynamical photoluminescence behaviour of the CDs. As the molecular origin of their photoluminescence is known, CDs with desired optical properties can be designed. PMID- 27711559 TI - Conductive multi-walled boron nitride nanotubes by catalytic etching using cobalt oxide. AB - Boron nitride nanotubes (BNNTs) are ceramic compounds which are hardly oxidized below 1000 degrees C due to their superior thermal stability. Also, they are electrically almost insulators with a large band gap of 5 eV. Thus, it is a challenging task to etch BNNTs at low temperature and to convert their electrical properties to a conductive behavior. In this study, we demonstrate that BNNTs can be easily etched at low temperature by catalytic oxidation, resulting in an electrically conductive behavior. For this, multi-walled BNNTs (MWBNNTs) impregnated with Co precursor (Co(NO3)2.6H2O) were simply heated at 350 degrees C under air atmosphere. As a result, diverse shapes of etched structures such as pits and thinned walls were created on the surface of MWBNNTs without losing the tubular structure. The original crystallinity was still kept in the etched MWBNNTs in spite of oxidation. In the electrical measurement, MWBNNTs with a large band gap were converted to electrical conductors after etching by catalytic oxidation. Theoretical calculations indicated that a new energy state in the gap and a Fermi level shift contributed to MWBNNTs being conductive. PMID- 27711560 TI - The effect of halide and iodate anions on the hydrogen-bonding network of water in aqueous nanodrops. AB - The hydration of halide and iodate anions was investigated using electrospray ionization (ESI) mass spectrometry and infrared photodissociation (IRPD) spectroscopy. The average cluster sizes, determined from the abundances of X (H2O)n (X- = F-, Cl-, Br-, I-, IO3-) in the ESI mass spectra, follow the order F- > IO3- ~ Cl- > Br- > I-. The average cluster sizes and solution hydration enthalpies of the halides increase linearly with decreasing ionic radii, but IO3- does not fit this trend. The correlation between average cluster sizes and solution hydration enthalpies indicates that there is a similar relationship between ion-water interactions in these large gas-phase clusters and in bulk solution. The abundances of odd number clusters between n = 49 and 55 for I-, Br- and Cl- are enhanced but those for F- and IO3- are not. I- and IO3- have nearly the same ionic radii, but evidence suggests that these ions interact with water molecules differently both in solution and in small clusters. IRPD spectra of I (H2O)n and IO3-(H2O)n, measured for select cluster sizes between n = 30 and 75 reveal differences in the hydrogen-bonding network of water molecules in these two ions even for sizes around n = 50. This indicates that differences in hydration motifs reported previously for the first hydration shells of I- and IO3 propagate to water molecules past the second solvation shell, a phenomenon that has not been reported previously for singly charged anions. PMID- 27711562 TI - Incorporating QM and solvation into docking for applications to GPCR targets. AB - A great number of GPCR crystal structures have been solved in recent years, enabling GPCR-targeted drug discovery using structure-based approaches such as docking. GPCRs generally have wide and open entrances to the binding sites, which render the binding sites readily accessible to solvent. GPCRs are also populated with hydrophilic residues in the extracellular regions. Thus, including solvent and polarization effects can be important for accurate GPCR docking. To test this hypothesis, a new docking protocol which incorporates quantum mechanical/molecular mechanical (QM/MM) calculations along with an implicit solvent model is developed. The new docking method treats the ligands and the protein residues in the binding sites as QM regions and performs QM/MM calculations with implicit solvent. The results of a test on all solved GPCR cocrystals show a significant improvement over the conventional docking method. PMID- 27711561 TI - Evidence of spin-temperature in dynamic nuclear polarization: an exact computation of the EPR spectrum. AB - In dynamic nuclear polarization (DNP) experiments, the compound is driven out-of equilibrium by the microwave (MW) irradiation of the radical electron spins. Their stationary state has been recently probed via electron double resonance (ELDOR) techniques showing, at low temperature, a broad depolarization of the electron paramagnetic resonance (EPR) spectrum under microwave irradiation. In this theoretical manuscript, we develop a numerical method to compute exactly the EPR spectrum in the presence of dipolar interactions. Our results reproduce the observed broad depolarisation and provide a microscopic justification for the spectral diffusion mechanism. We show the validity of the spin-temperature approach for typical radical concentration used in dissolution DNP protocols. In particular once the interactions are properly taken into account, the spin temperature is consistent with the non-monotonic behavior of the EPR spectrum with a wide minimum around the irradiated frequency. PMID- 27711563 TI - Preparation and electrochemical properties of Li2MoO3/C composites for rechargeable Li-ion batteries. AB - Layered Li2MoO3 is a potential candidate for a high-capacity positive electrode material for Li-ion batteries because of its excess lithium composition. However, the difficulty of single-phase preparation and its insulating nature are drawbacks for its application in lithium-ion batteries. A small quantity of acetylene black added in the starting material solves these drawbacks, i.e. the formation of impurity phases and the low conductivity. As a result, a Li2MoO3/C composite is successfully synthesized with the simple addition of acetylene black. Since the electronic conductivity of the composite is enhanced to more than 1000 times higher than that of bare Li2MoO3, the Li2MoO3/C composite delivers approximately 230 mA h g-1 of initial discharge capacity in a voltage range of 1.5-4.3 V, while carbon-free Li2MoO3 shows only 110 mA h g-1 of initial discharge capacity. During the initial lithium extraction and insertion, a partial transformation from a layered into a cation-disordered cubic structure is evidenced in the Li2MoO3/C composite electrode by X-ray diffraction. PMID- 27711564 TI - The i-TTM model for ab initio-based ion-water interaction potentials. II. Alkali metal ion-water potential energy functions. AB - A new set of i-TTM potential energy functions describing the interactions between alkali metal ions and water molecules is reported. Following our previous study on halide ion-water interactions [J. Phys. Chem. B, 2016, 120, 1822], the new i TTM potentials are derived from fits to CCSD(T) reference energies and, by construction, are compatible with the MB-pol many-body potential, which has been shown to accurately predict the properties of water from the gas to the condensed phase. Within the i-TTM formalism, two-body repulsion, electrostatic, and dispersion energies are treated explicitly, while many-body effects are represented by classical induction. The accuracy of the new i-TTM potentials is assessed through extensive comparisons with results obtained from different ab initio methods, including CCSD(T), CCSD(T)-F12b, DF-MP2, and several DFT models, as well as from polarizable force fields for M+(H2O)n clusters with M+ = Li+, Na+, K+, Rb+, and Cs+, and n = 1-4. PMID- 27711565 TI - Understanding the effect of an in situ generated and integrated spinel phase on a layered Li-rich cathode material using a non-stoichiometric strategy. AB - Recently, spinel-layered integrated Li-rich cathode materials have attracted great interest due to the large enhancement of their electrochemical performances. However, the modification mechanism and the effect of the integrated spinel phase on Li-rich layered cathode materials are still not very clear. Herein, we have successfully synthesized the spinel-layered integrated Li rich cathode material using a facile non-stoichiometric strategy (NS-LNCMO). The rate capability (84 mA h g-1vs. 28 mA h g-1, 10 C), cycling stability (92.4% vs. 80.5%, 0.2 C), low temperature electrochemical capability (96.5 mA h g-1vs. 59 mA h g-1, -20 degrees C), initial coulomb efficiency (92% vs. 79%) and voltage fading (2.77 V vs. 3.02 V, 200 cycles@1 C) of spinel-layered integrated Li-rich cathode materials have been significantly improved compared with a pure Li-rich phase cathode. Some new insights into the effect of the integrated spinel phase on a layered Li-rich cathode have been proposed through a comparison of the structure evolution of the integrated and Li-rich only materials before and after cycling. The Li-ion diffusion coefficient of NS-LNCMO has been enlarged by about 3 times and almost does not change even after 100 cycles indicating an enhanced structure stability. The integration of the spinel phase not only enhances the structure stability of the layered Li-rich phase during charging-discharging but also expands the interslab spacing of the Li-ion diffusion layer, and elongates TM-O covalent bond lengths, which lowers the activation barrier of Li+ transportation, and alleviates the structure strain during the cycling procedure. PMID- 27711566 TI - Light-induced charge separation in a P3HT/PC70BM composite as studied by out-of phase electron spin echo spectroscopy. AB - A composite material of semiconducting polymer P3HT and fullerene derivative PC70BM was studied by means of electron spin echo (ESE) spectroscopy. The out-of phase ESE signal was observed under laser irradiation of the composite at low temperature. We assume that during the charge separation process firstly the spin correlated radical pairs in the singlet-polarized spin state are formed, and then the net polarization of radical pairs arises due to spin evolution. Both types of polarizations contribute to the out-of-phase ESE signal in the case of non-ideal microwave pulses. Analytical calculation of the echo shape for both types of initial polarization revealed that the contribution of the net polarization becomes zero after averaging over the whole EPR spectrum of the radical pair. This behavior was experimentally confirmed; thus the analysis of the out-of-phase ESE signal was simplified. Interspin distance distributions in the charge transfer state were obtained by modeling the out-of-phase ESE envelope modulation measured at different delays after laser flash TDAF from 300 ns to 3.3 MUs at a temperature of 65 K. Due to geminate recombination and diffusion of the radicals from the interface the distribution becomes significantly broader with larger distances prevailing at longer TDAF values. The average distance between charges increases from 3.5 nm to 5.6 nm with an increase in TDAF. PMID- 27711567 TI - Design and simple synthesis of composite Bi12TiO20/Bi4Ti3O12 with a good photocatalytic quantum efficiency and high production of photo-generated hydroxyl radicals. AB - Hybrid Bi12TiO20/Bi4Ti3O12 composites with different Bi : Ti molar ratios were successfully fabricated using a one-step solid-state calcination. These samples were characterized using X-ray diffraction, specific surface area analysis, scanning electron microscopy, high-resolution microscopy, selected-area electron diffraction, X-ray photoelectron spectroscopy, UV-vis diffuse reflection spectroscopy, photoluminescence analyses, and photocurrent and electrochemical impedance spectroscopy. Some specified techniques were also used to investigate the photocatalytic properties and the formation of radical species under UV-vis irradiation. The composites provide an efficient pathway for photo-produced electrons and holes to diffuse and transfer to the exterior of the particles for photodegradation, because of the good contact between hybrid Bi12TiO20 and Bi4Ti3O12. Therefore, the hybrid Bi12TiO20/Bi4Ti3O12 can prolong the carrier lifetime as compared to any individual material (Bi12TiO20 or Bi4Ti3O12). In particular, the hybrid Bi12TiO20/Bi4Ti3O12 composite with a Bi : Ti ratio of 12 : 6 had the longest photo-generated carrier lifetime and produced the maximum amount of hydroxyl radicals during UV-vis irradiation; therefore, it demonstrated the best photo-catalytic properties. A Z-scheme mechanism was proposed to explain the hydroxyl radical yield and photodegradation. PMID- 27711568 TI - Generation of highly reactive oxygen species on metal-supported MgO(100) thin films. AB - The formation of highly reactive oxygen species (ROS) on metal oxide surfaces has attracted considerable interest due to their diverse applications. In this work, we have performed density functional theory calculations to investigate the co adsorption of oxygen and water on ultrathin MgO(100) films deposited on a Mo(100) substrate. We reveal that molecular oxygen can be completely decomposed stepwise with the assistance of water. Consequently, a series of highly ROS including superoxide, hydroperoxide, hydroxyl and single oxygen adatoms are formed on Mo(100) supported MgO(100) thin films. The reaction barriers accompanied by the generation of ROS are reported, and the influence of the thickness of MgO(100) films is also discussed. The promising routes to produce these species provide valuable information to understand the importance of synergy effects between the substrate, the co-adsorbed species, and the film thickness in multiphase catalyst design. PMID- 27711569 TI - Excited-state relaxation of the solar cell dye D49 in organic solvents and on mesoporous Al2O3 and TiO2 thin films. AB - We present an ultrafast UV-Vis-NIR transient absorption study of the donor acceptor solar-cell dye D49 in diisopropyl ether, THF and acetonitrile, as well as on mesoporous Al2O3 and TiO2 thin films. Photoexcitation at 505 nm initially populates the first electronically excited state of the dye having significant intramolecular charge transfer character ("S1/ICT"). On Al2O3 and in the three organic solvents, the dynamics are fully explained in terms of S1/ICT stabilisation (by reorientation of adjacent solvent or D49 molecules and collisional cooling), intramolecular vibrational redistribution and S1/ICT -> S0 electronic decay. A substantial decrease of the S1/ICT lifetime is observed with increasing polarity of the surrounding medium suggesting an acceleration of internal conversion. In agreement with these results, the addition of the nonpolar co-adsorbent deoxycholic acid (DCA) to the Al2O3 surface leads to a substantial increase of the S1/ICT lifetime. DCA spacers reduce the local polarity around the dye molecules, thus interrupting D49 "self-solvation". These results are in contrast to a recent experimental study for the indoline dye D131 on Al2O3, where charge transfer from electronically excited D131 to adjacent dye molecules was proposed (Cappel et al., Sci. Rep., 2016, 6, 21276). We do not see evidence for charge transfer processes between D49 molecules and also not for electron injection from D49 into Al2O3 trap states. Charge separation is only observed for D49 bound to TiO2 thin films, with efficient injection of electrons into the conduction band of the semiconductor via formation of a [D49+e-] complex and a transient Stark effect signalling the formation of mobile electrons upon dissociation of the complex. PMID- 27711570 TI - Probing the microhydration of metal carbonyls: a photoelectron velocity-map imaging spectroscopic and theoretical study of Ni(CO)3(H2O)n. AB - A series of microhydrated nickel carbonyls, Ni(CO)3(H2O)n- (n = 0-4), are prepared via a laser vaporization supersonic cluster source in the gas phase and identified by mass-selected photoelectron velocity-map imaging spectroscopy and quantum chemical calculations. Vertical detachment energies for the n = 1-4 anions are measured from the photoelectron spectra to be 1.429 +/- 0.103, 1.698 +/- 0.090, 1.887 +/- 0.080, and 2.023 +/- 0.074 eV, respectively. The C-O stretching vibrational frequencies in the corresponding neutral clusters are determined to be 1968, 1950, 1945, and 1940 cm-1 for n = 1-4, respectively, which are characteristic of terminal CO. It is determined that the hydrogen atom of the first water molecule is bound to the nickel center. Addition of a second water molecule prefers solvation at the carbonyl terminal. Spectroscopy combined with theory suggests that the solvation of nickel tricarbonyl is dominated by a water ring network. The present findings would have important implications for the fundamental understanding of the multifaceted mechanisms of the multibody interaction of water and carbon monoxide with transition metals. PMID- 27711571 TI - Kinetics of prebiotic depsipeptide formation from the ester-amide exchange reaction. AB - In this work, we introduce a kinetic model to study the effectiveness of ester mediated amide bond formation under prebiotic conditions. In our previous work, we found that a simple system composed of alpha-hydroxy acids and alpha-amino acids is capable of forming peptide bonds via esterification followed by the ester-amide exchange reaction. To further understand the kinetic behavior of this copolymerization, we first tracked the growth of initial species from a valine/lactic acid mixture in a closed system reactor. A mathematical model was developed to simulate the reactions and evaluate the rate constants at different temperatures. We found these reactions can be described by the empirical Arrhenius equation even when reaction occurred in the solid (dry) state. Further calculations for activation parameters showed that the ester-mediated pathway facilitates amide bond formation by lowering activation entropies. These results provide a theoretical framework that illustrates why the ester-mediated pathway for peptide bond formation is efficient and why it would have been more favorable on the early Earth, compared to peptide bond formation without the aid of hydroxy acids. PMID- 27711572 TI - Influence of asymmetric depletion of solvents on the electric double layer of charged objects in binary polar solvent mixtures. AB - For binary solvent mixtures composed of ions and two kinds of polar solvents, the electric double layer near a charged object is strongly affected by not only the binary solvent composition but also the nature of the solvents, such as the volume and dipole moment of the solvent molecule. Accounting for the difference in sizes of solvents and the orientational ordering of solvent dipoles, we theoretically obtain general expressions for the spatial distribution functions of solvents and ions, in planar geometry and within the mean-field approach. While focusing on long-range electrostatic interaction and neglecting short-range interactions such as preferential solvation, our approach predicts an asymmetric depletion of the two solvents from the charged surface and a behavior of decreased permittivity of the binary solvent mixture. Furthermore, we suggest that the key factor for the depletion is the ratio of the solvent dipole moment to the solvent volume. The influence of the binary solvent composition, the volume of solvent and the dipole moment of the solvent on the number density of solvents, the permittivity and the differential capacitance is presented and discussed. We conclude that accounting for the difference in the volume and dipole moment between polar solvents is necessary for a new approach to represent more realistic situations such as preferential solvation. PMID- 27711573 TI - A comparative study of small 3d-metal oxide (FeO)n, (CoO)n, and (NiO)n clusters. AB - Geometrical and electronic structures of the 3d-metal oxide clusters (FeO)n, (CoO)n, and (NiO)n are computed using density functional theory with the generalized gradient approximation in the range of 1 <= n <= 10. It is found that the cluster geometries are similar in the (FeO)n and (CoO)n series but noticeably different in the (NiO)n series for several values of n. All of the lowest total energy states are found to possess relatively small spin multiplicities and are either antiferromagnetic or ferrimagnetic except for the states of (NiO)3, (NiO)4, (NiO)9, and (NiO)10, which are ferromagnetic. The computed polarizabilities per atom undergo a steep decrease when compared to the atomic values of the MO monomers (M = Fe, Co, and Ni). Surprisingly, the polarizability does not strongly depend on either M or n in all the considered series when n varies from 3 to 10. The binding energies per atom are the largest in the (FeO)n series, followed by the binding energies of (CoO)n and (NiO)n. PMID- 27711574 TI - Classification of hydrogen bond flips in small water polyhedra applied to concerted proton tunneling. AB - Recently a new mechanism of proton tunneling in a prism-like water hexamer was revealed [Richardson et al., Science, 2016, 351, 1310]. The tunneling motion involves the concerted breaking of two hydrogen bonds and rotations of two nearest water molecules. Eventually, this structural transformation means flipping one of the hydrogen bonds without the creation of defects in the hydrogen bond network. On the surface of polyhedral water clusters, there are five essentially different types of hydrogen bonds, and only two of them can be changed in this manner. In this article, the topological classification of such transformations for five small water polyhedra: triangular, pentagonal, and hexagonal prisms as well as cube and polyhedron 4454, consisting of four square and four pentagonal faces, is presented. Our classification includes the enumeration of all possible one-bond-flips with consideration of the types of hydrogen bonds on the polyhedral surface. Attention is paid to the most stable proton configurations which can be studied in experiments. It was established that a number of one-bond-flip transitions between the low energy configurations are possible in clusters in the shape of triangular and pentagonal prisms.

AB - The present study discusses the design and development of a dye sensitized solar cell (DSSC) using a hybrid composite of ZnO nanoparticles (ZnO NP) and silica nanospheres (SiO2 NS). A ~22% enhancement in the overall power conversion efficiency (PCE, eta) was observed for the device fabricated with a binary hybrid composite of 1 wt% SiO2 NS and ZnO NP compared to the pristine ZnO NP device. A systematic investigation revealed the dual function of the silica nanospheres in enhancing the device efficacy compared to the bare ZnO NP based device. Sub micron sized SiO2 NS can boost the light harvesting efficiency of the photoanode by optical confinement, resulting in increased propagation length of the incident light by multiple internal reflections, which was confirmed by UV-Vis diffused reflectance spectroscopy. Electrochemical impedance spectroscopic (EIS) analysis showed a reduced recombination of photo-generated electrons to the I-/I3- redox shuttle in the case of the composite photoanode. The higher recombination resistance (Rct) in the case of a 1 wt% composite indicates that the SiO2 NS serves as a partial energy barrier layer to retard the interfacial recombination (back transfer) of photo-generated electrons at the working electrode/electrolyte interface, increasing the device efficiency. PMID- 27711576 TI - Dynamics of silver ions in AgI doped Ag2O-SeO2-MoO3 mixed former glasses. AB - We have studied the dynamics of silver ions in AgI-doped Ag2O-SeO2-MoO3 mixed former glasses in wide frequency and temperature ranges. We have observed that the ionic conductivity exhibits a mixed glass network former effect for low AgI content. The scaling for the conductivity spectra shows that the mechanism of charge carrier dynamics is independent of temperature and composition. We have obtained a mobile Ag+ ion concentration from the Nernst-Einstein relation, which is found to be independent of temperature, but slightly dependent on composition. We have also obtained the characteristic mean square displacement of the silver ions from the mapping of the conductivity spectra in the time domain. It is observed that the composition dependence of the characteristic displacement is opposite to that of the conductivity. We have also studied the influence of the network structure of these glasses on ion dynamics using infrared spectra and established a correlation between the ion dynamics and the SeO32- structural units. It is observed that the available hopping sites for Ag+ ions increase in the glass network with the increase of non-bridging oxygens of SeO32- units. PMID- 27711577 TI - Enhanced low-temperature ionic conductivity via different Li+ solvated clusters in organic solvent/ionic liquid mixed electrolytes. AB - We investigate Li+ coordination in mixed electrolytes based on ionic liquids (ILs) and organic solvents and its relation with the macroscopic properties such as phase behaviour and ionic conductivity. Using Raman spectroscopy we determine the solvation shell around Li+ in mixtures formed by the IL N-butyl-N methylpyrrolidinium bis(trifluoromethanesulfonyl)imide, the organic solvents ethylene carbonate and dimethyl carbonate (EC : DMC 1 : 1), and the salt LiTFSI. We find that the organic solvent molecules preferentially solvate Li+ as long as there are enough of them. Our results are consistent with a model where Li(EC)3(DMC)1 and Li(EC)2(DMC)2 are the main complexes formed by the organic solvent molecules and where TFSI- mainly participates in Li(TFSI)2- clusters. As the amount of organic solvent is increased, the number of TFSI- around Li+ rapidly decreases showing a higher affinity of the organic solvents to solvate Li+. The changes in the local configurations are also reflected in the ionic conductivity and the phase behaviour. The formation of larger clusters leads to a decrease in the conductivity, whereas the presence of several different clusters at intermediate compositions effectively hinders crystallization at low temperatures. The result is an enhanced low-temperature ionic conductivity in comparison with the pure IL or organic solvent electrolytes.

AB - Luminescent-magnetic bifunctional NaGdF4:Dy3+ nanofibers and nanobelts have been successfully fabricated by a combination of electrospinning followed by subsequent calcination with fluorination technology for the first time. The structure, morphologies, and luminescence and magnetic properties of the synthesized materials have been investigated by a variety of techniques. X-ray diffraction (XRD) analysis shows that as-prepared NaGdF4:Dy3+ nanostructures are pure hexagonal structures. Scanning electron microscopy (SEM) observations indicate that directly electrospinning-made PVP/[NaNO3 + Gd(NO3)3 + Dy(NO3)3] composite nanofibers and nanobelts have smooth surfaces, good dispersion and uniform size, and surfaces of NaGdF4:Dy3+ nanofibers and nanobelts become rough after calcination and fluorination processes. The mean diameters of PVP/[NaNO3 + Gd(NO3)3 + Dy(NO3)3] composite nanofibers and NaGdF4:0.5%Dy3+ nanofibers are, respectively, 402.20 +/- 2.39 nm and 246.06 +/- 5.84 nm at the confidence level of 95%. The mean widths and thicknesses of PVP/[NaNO3 + Gd(NO3)3 + Dy(NO3)3] composite nanobelts and NaGdF4:0.5%Dy3+ nanobelts are 4.16 +/- 0.17 MUm and 279 nm, and 0.83 +/- 0.01 MUm and 130 nm, respectively. Under the excitation of 274 nm ultraviolet light, NaGdF4:Dy3+ nanofibers and nanobelts show the predominant blue and yellow emission peaks at 478 and 570 nm corresponding to the 4F9/2 -> 6HJ/2 (J = 15, 13) energy level transitions of Dy3+ ions, respectively. NaGdF4:0.5%Dy3+ nanofibers have higher photoluminescence intensity than their nanobelt counterpart. In addition, all the NaGdF4:Dy3+ nanofibers and nanobelts display superparamagnetic properties. The NaGdF4:0.5%Dy3+ nanobelts show the highest magnetization, and NaGdF4:0.5%Dy3+ nanofibers have slightly higher magnetization values than NaGdF4 nanofibers. NaGdF4:Dy3+ nanofibers and nanobelts simultaneously possess excellent luminescence and enhanced superparamagnetic properties, which make them ideally suitable for application in many fields such as solid-state lasers, lighting and displays, and magnetic resonance imaging. The design conception and construction strategy developed in this work may provide some new guidance for the synthesis of other rare earth fluoride nanostructures with various morphologies.

AB - In this work, the effects of the structural (crystallite size, stress) and electronic parameters (band gap, lifetime) on the photoelectrocatalysis and electron transport over CdSe electrodeposited inside TiO2-nanotubes (CdSe@TiO2NT) were investigated. Density functional theory (DFT) calculations of TiO2 were used to elucidate the electronic band structure and to correlate with experimental values. CdSe was grown by pulsed electrodeposition into previous and late thermal treated TiO2NT (Sample-PTT and Sample-LTT, respectively) without blocking the nanotube's entrance. The Rietveld refinement method was used to obtain information from crystallographic data of each photoelectrode. The lattice strains calculated from the Rietveld analysis for Sample-PTT and Sample-LTT were 0.472 and 0.540, and the average volume of the TiO2-anatase unit cell increased from 133.235(0) A3 to 136.950(6) A3, respectively. Sample-PTT exhibited higher experimental electron lifetime, larger than 1.0 order of magnitude compared to Sample-LTT photoanodes. The band structures and DOS obtained by computational modelling showed theoretical band gap values of 2.54 eV and 2.75 eV, which were close to the experimental values. All studies evidenced a strong dependence of the electronic properties of the CdSe@TiO2 samples on their morphology, and, consequently, on their photoelectrochemical activity in water splitting.

AB - The recent synthesis of monolayer borophene (triangular boron monolayer) on a substrate has opened the era of boron nanosheets (Science, 2015, 350, 1513), but the structural instability and a need to explore the novel physical properties are still open issues. Here we demonstrated that borophene can be stabilized by full surface hydrogenation (borophane), from first-principles calculations. Most interestingly, our calculations show that borophane has direction-dependent Dirac cones, which are mainly caused by the in-plane px and py orbitals of boron atoms. The Dirac fermions possess an ultrahigh Fermi velocity of up to 3.5 * 106 m s-1 under the HSE06 level, which is 4 times higher than that of graphene. The Young's moduli are calculated to be 190 and 120 GPa nm along two different directions, which are comparable to those of steel. The ultrahigh Fermi velocity and good mechanical features render borophane ideal for nanoelectronic applications. PMID- 27711581 TI - In situ Raman investigation of electrolyte solutions in the vicinity of graphite negative electrodes. AB - The structure of electrolyte solutions plays an important role in the lithium-ion intercalation reaction at graphite negative electrodes. The solvation structure of an electrolyte solution in bulk has been investigated previously. However, the structure of an electrolyte solution at the graphite negative electrode/electrolyte solution interface, where the lithium-ion intercalation reaction occurs is more important. In this study, the structure of electrolyte solutions in the vicinity of a graphite negative electrode was investigated using in situ Raman spectroscopy during the 1st reduction process in 1 mol dm-3 LiClO4/ethylene carbonate (EC) + diethyl carbonate (DEC) (1 : 1 volume ratio), 1 mol dm-3 LiCF3SO3/propylene carbonate (PC), and 1 mol dm-3 LiCF3SO3/PC + tetraethylene glycol dimethyl ether (tetraglyme) (20 : 1 volume ratio). As a result, in the electrolyte solutions in which the lithium-ion intercalation reaction can occur (LiClO4/EC + DEC and LiCF3SO3/PC + tetraglyme), the Raman spectra of free solvent molecules (EC or PC) and anions showed a positive vibrational frequency shift during the co-intercalation reaction, and these shifts returned to their original positions during the lithium-ion intercalation reaction. On the other hand, there is no vibrational frequency shift in LiCF3SO3/PC, an electrolyte in which the lithium-ion intercalation reaction cannot occur. Based on our results, the relationship between the Raman shift and the solid electrolyte interphase (SEI) formation process was discussed. PMID- 27711582 TI - Evidence for dissolved hydrogen in the mixed ionic-electronic conducting perovskites La0.6Sr0.4FeO3-delta and SrTi0.7Fe0.3O3-delta. AB - Two mixed ionic-electronic conducting, Fe-containing perovskites were investigated regarding their reducibility in dry H2, namely lanthanum strontium ferrite (LSF4, La0.6Sr0.4FeO3-delta) and strontium titanium ferrite (STF3, SrTi0.7Fe0.3O3-delta). Upon treatment under comparable reduction conditions, LSF4 is by far more affected by reduction and is reduced more deeply than STF3. Thermal treatments of fully oxidized or slightly reduced LSF4/STF3 at decreased O2 partial pressure lead to spontaneous desorption of O2. Temperature-programmed desorption (TPD) spectra of H2 reveal distinct differences in H2 and H2O desorption. A simple mass balance of H2 reveals that oxygen vacancies formed on STF3 are more resilient towards O2 re-oxidation compared to those on LSF4. The results also imply that substantial amounts of hydrogen are dissolved in the bulk of LSF4 or STF3. 4.9 * 10-2 mol H2 per mol LSF4 and 1.6 * 10-2 mol H2 per mol STF3 are incorporated if the specimens are heated in flowing/dry H2 up to 550 degrees C and 612 degrees C, respectively. For LSF4 this equals about 13 hypothetical ML of H2 and for STF3 about 20 hypothetical ML of H2. This conclusion is also supported by Fourier-transform infrared spectroscopy (FT-IR). FT-IR reveals water formation during static H2 treatment of LSF4/STF3, which indicates perovskite reduction. Furthermore, both samples behave extraordinarily hydrophobic and no chemistry involving surface hydroxy groups was observed. PMID- 27711583 TI - Magnetic behavior of superatomic-fullerene assemblies. AB - It has recently been possible to synthesize ordered assemblies composed of magnetic superatomic clusters Ni9Te6(PEt3)8 separated by C60 and study their magnetic behavior. We have carried out theoretical studies on model systems consisting of magnetic superatoms separated by non-magnetic species to examine the evolution in magnetic response as the nature of the magnetic superatom (directions of spin quantization), the strength of isotropic and anisotropic interactions, the magnetic anisotropy energy, and the size of the assembly are varied. We have examined square planar configurations consisting of 16, 24 and 48 sites with 8, 12 and 24 magnetic superatoms respectively. The magnetic atoms are allowed 2 or 5 orientations. The model Hamiltonian includes isotropic exchange interactions with second nearest neighbor ferromagnetic and nearest neighbor antiferromagnetic couplings and anisotropic Dzyaloshinskii-Moriya interactions. It is shown that the inclusion of Dzyaloshinskii-Moriya interaction that cause spin canting is necessary to get qualitative response as observed in experiments. PMID- 27711584 TI - Emission in Gd6O5F8:Yb3+,Er3+ micro-particles for multimodal luminescence and temperature sensing upon 980 nm excitation. AB - Mono-dispersed Gd6O5F8:Yb3+/Er3+ micro-particles with different doping concentrations (Er3+: 0.1-1%) were synthesized by a facile hydrothermal route. The emission spectra, luminescent dynamic power-dependence and temperature sensing of up-conversion photoluminescence were investigated in detail. Under 980 nm excitation, the as-prepared samples exhibit intense red up-conversion and NIR emissions, which are influenced by the doping concentrations of Er3+ within Gd6O5F8. With increasing concentrations of Er3+ ions, the visible up-conversion emissions first increase and then decrease, but NIR down-conversion emissions display a distinct trend, in which one peak at 1010 nm is highly suppressed and another at 1530 nm is increased quickly. Furthermore, the 980 nm excited optical temperature sensing property of the synthesized sample is realized over a wide temperature range by monitoring the intensity of up-conversion luminescence. The study provides a novel strategy based on lanthanide oxy-fluoride micro-particles for multifunctional displays, lighting and temperature sensing in a single system. PMID- 27711585 TI - Rational selection of amorphous or crystalline V2O5 cathode for sodium-ion batteries. AB - Vanadium oxide (V2O5), as a potential positive electrode for sodium ion batteries (SIBs), has attracted considerable attention from researchers. Herein, amorphous and crystalline V2O5 cathodes on a graphite paper without a binder and conductive additives have been synthesized via facile anodic electrochemical deposition following different heat treatments. Both the amorphous V2O5 (a-V2O5) cathode and crystalline V2O5 (c-V2O5) cathode show good rate cycling performance and long cycling life. After five rate cycles, the reversible capacities of both the cathodes were almost unchanged at different current densities from 40 to 5120 mA g-1. Long cycling tests with 10 000 cycles were carried out and the two cathodes exhibit excellent cycling stability. The c-V2O5 cathode retains a high specific capacity of 54 mA h g-1 after 10 000 cycles at 2560 mA g-1 and can be charged within 80 s. Interestingly, the a-V2O5 cathode possesses higher reversible capacities than the c-V2O5 cathode at low current densities, whereas it is inversed at high current densities. The c-V2O5 cathode shows faster capacity recovery from 5120 to 40 mA g-1 than the a-V2O5 cathode. When discharged at 80 mA g-1 (long discharge time of 140 min) and charged at 640 mA g-1 (short charge time of 17 min), the a-V2O5 cathode shows a higher discharge capacity than its c-V2O5 counterpart. The different electrochemical performance of a-V2O5 and c-V2O5 cathodes during various electrochemical processes can provide a rational selection of amorphous or crystalline V2O5 cathode materials for SIBs in their practical applications to meet the variable requirements. PMID- 27711586 TI - Charge-transfer and isomerization reactions of trans-4-(N-arylamino)stilbenes. AB - We studied the excited-state dynamics of trans-4-(N-arylamino)stilbenes with aryl = phenyl (p1H), 4-methoxyphenyl (p1OM), or 4-cyanophenyl (p1CN) in solvents of varied polarity and viscosity by using femtosecond transient absorption and time correlated single photon counting techniques. In nonpolar solvents the decay is triexponential, in which the rapid component corresponds to vibrational cooling combined with solvation, the intermediate temporal component 41-120 ps to trans cis isomerization, and the long one ~1 ns to fluorescence decay of the S1 state. The S1 state has a delocalized geometry and charge-transfer characteristics, corresponding to a planar intramolecular charge transfer (PICT) state. In polar solvents, an excited-state absorption band appears near 520 and 480 nm for p1OM and p1CN, respectively but not for p1H. This band has a rise lifetime of 4.3/7.5, 16.3/9.4, and 29.5/16 ps for p1CN/p1OM in acetonitrile (ACN), dimethylformamide (DMF), and dimethyl sulfoxide (DMSO), respectively and matches the decay of the 600 nm PICT band. This band is thus assigned to the absorption of a singlet twisted intramolecular charge transfer state (TICT). The conversion rate decreases as the solvent viscosity is increased and is consistent with a large structural variation amplitude. Theoretical calculations using density functional theory (DFT), method PEB0, were employed to obtain the optimized structures and energies of those states. The PICT state possesses delocalized pi electrons along the molecule. The TICT for p1CN is formed by twisting about the aminostilbene benzonitrile C-N bond by ~90 degrees , but it is about the stilbene-aniline C-N bond for p1OM. We observed faster conversion rates for p1CN in alcoholic solvents, in which the lifetimes for both the PICT and TICT states are shortened to 20-99 ps and 120-660 ps, respectively, as a result of solvent-solute H-bonding interactions. In p1OM, the TICT state has an elongated C[double bond, length as m dash]C bond in the stilbene moiety, which might facilitate the trans-cis isomerization reaction and thus account for the relatively short lifetime of 58 420 ps in polar solvents. PMID- 27711587 TI - Towards understanding the kinetic behaviour and limitations in photo-induced copper(i) catalyzed azide-alkyne cycloaddition (CuAAC) reactions. AB - The kinetic behaviour of the photo-induced copper(i) catalyzed azide-alkyne cycloaddition (CuAAC) reaction was studied in detail using real-time Fourier transform infrared (FTIR) spectroscopy on both a solvent-based monofunctional and a neat polymer network forming system. The results in the solvent-based system showed near first-order kinetics on copper and photoinitiator concentrations up to a threshold value in which the kinetics switch to zeroth-order. This kinetic shift shows that the photo-CuAAC reaction is not susceptible from side reactions such as copper disproportionation, copper(i) reduction, and radical termination at the early stages of the reaction. The overall reaction rate and conversion is highly dependent on the initial concentrations of photoinitiator and copper(ii) as well as their relative ratios. The conversion was decreased when an excess of photoinitiator was utilized compared to its threshold value. Interestingly, the reaction showed an induction period at relatively low intensities. The induction period is decreased by increasing light intensity and photoinitiator concentration. The reaction trends and limitations were further observed in a solventless polymer network forming system, exhibiting a similar copper and photoinitiator threshold behaviour. PMID- 27711588 TI - Coalescence behavior of liquid immiscible metal drops in two-wall confinement. AB - Molecular dynamics (MD) simulations are performed to investigate the coalescence of the liquid Al and Pb drops in the graphene (G) walls and pillared-graphene (PG) walls. The confining walls can affect the coalescence dynamics of two adjacent films by restricting the movement of one of the metal drops; however, the coalescence behavior is different in the G-walls and the PG-walls. Two un contacted films can still merge into one bigger drop because of the restricting effect of the walls, in which the movement of the Pb drop plays a predominant role. The coalescence time decreases with the decrease of the confining space. Our findings demonstrate that the coalescence dynamics can be controlled by tuning the confining space or wall surface. PMID- 27711589 TI - Multivalent bonds in self-assembled bundles of ultrathin gold nanowires. AB - Ultrathin gold nanowires are unusual colloidal objects that assemble into bundles with line contacts between parallel wires. Each molecule in the contact line interacts with many ligand and solvent molecules. We used X-ray scattering and electron microscopy to study how these interactions control assembly. PMID- 27711590 TI - pH-Responsive drug release and NIR-triggered singlet oxygen generation based on a multifunctional core-shell-shell structure. AB - A multifunctional platform with pH-responsive drug release and near-infrared (NIR) light-triggered photodynamic therapy (PDT) was designed and prepared using the novel core-shell-shell structure. The multifunctional platform consists of an upconversion nanoparticle (UCNP) emission core, a photosensitizer methylene blue (MB) embedded dense silica sandwich shell, and a polyethyleneimine conjugated folic acid (PEI-FA) gated mesoporous silica (MS) outmost shell with doxorubicin hydrochloride (DOX) loaded inside. The simulated drug release experiments revealed that DOX will release from the nanoparticles because of the distortion in the PEI-FA layer under acidic conditions. Moreover, under 980 nm NIR irradiation, a 660 nm red light emission was excited, activating MB to generate a singlet oxygen (1O2), which acts as the PDT drug. The multifunctional platform integrated pH-responsive drug release and UCNP-based PDT drug together show promising potential in nanomedicine for future chemotherapy and NIR-triggered PDT. PMID- 27711591 TI - Black-box determination of temperature-dependent susceptibilities for crystalline organic radicals with complex magnetic topologies. AB - In all but the simplest crystal structures, the identification of all relevant interactions between magnetic sites as well as the setup of magnetic model spaces, which are necessary for modeling macroscopic magnetism, are tedious and error-prone tasks. Here, we present a procedure to generate magnetic susceptibility versus temperature curves using only a crystal structure as input. The procedure, which is based on the first-principles bottom-up approach [Deumal et al., J. Phys. Chem. A, 2002, 106, 1299], is designed in a way to require as little user interference as possible. We employ quantum chemical calculations to parametrize a Heisenberg Hamiltonian, which is set up and diagonalized for different magnetic model spaces to ensure convergence of the model. We apply the procedure to several 6-oxo-verdazyl radical structures, including newly synthesized compounds, and compare the results to data we obtained from magnetic susceptibility measurements as well as published data to further benchmark our procedure. Furthermore, the different impact of certain dominating coupling constants is systematically analyzed. PMID- 27711592 TI - Cation-cation and anion-anion complexes stabilized by halogen bonds. AB - Stable minima showing halogen bonds between charged molecules with the same sign have been explored by means of theoretical calculations. The dissociation transition states and their corresponding barriers have also been characterized. In all cases, the results indicate that the complexes are thermodynamically unstable but kinetically stable with respect to the isolated monomers in gas phase. A corrected binding energy profile by removing the charge-charge repulsion of the monomers shows a profile similar to the one observed for the dissociation of analogous neutral systems. The nature of the interaction in the minima and TSs has been analyzed using the symmetry adapted perturbation theory (SAPT) method. The results indicate the presence of local favorable electrostatic interactions in the minima that vanish in the TSs. Natural bond orbital (NBO) and "atoms-in molecules" (AIM) theories were used to analyze the complexes, obtaining good correlations between Laplacian and electron density values with both bond distances and charge-transfer energy contributions E(2). The largest E(2) orbital interaction energies for cation-cation and anion-anion complexes are 561.2 and 197.9 kJ mol-1, respectively. PMID- 27711593 TI - Multifunctional heterostructures constructed using MoS2 and WS2 nanoribbons. AB - Using first-principles calculations based on nonequilibrium Green's function together with density functional theory, we investigated the electronic transport properties of some devices consisting of armchair and zigzag MoS2NRs/WS2NRs in plane heterostructures. The results indicate that these heterostructures exhibit rectifying performance, which are depressed as the number of WS2NR unit cell decreases. In addition, the NDR effect is observed and can be modulated. Importantly, the zigzag MoS2NRs/WS2NRs heterostructures can be used as spintronic devices because of their tunable spin filtering behavior and NDR effect. The devices with WS2NRs electrode display a better NDR effect and spin filtering behavior. The unique properties of these heterostructures suggest promising applications in the next generation nanoelectronic devices. PMID- 27711594 TI - Vapour adsorption kinetics: statistical rate theory and zeta adsorption isotherm approach. AB - The equilibrium zeta adsorption isotherm for vapours indicates the amount adsorbed is finite for vapour-phase pressures approaching the saturation value, and is strongly supported by experimental measurements for a number of different vapour-solid surface systems. This isotherm assumes the adsorbate consists of differently sized molecular clusters in local equilibrium rather than the adsorbate being in layers. We use the local-equilibrium approximation and develop a method to determine the expression for chemical potential of the adsorbate in terms of the amount adsorbed, nA(t). This allows us to apply statistical rate theory to calculate nA(t) at five different vapour-phase pressures, xV (=PV/Psat), in terms of a parameter, re. Statistical rate theory indicates that re describes the dynamics of a given isolated system under equilibrium conditions. We consider two methods for determining the value of re that give the best agreement with the measurements performed at each of five values of xV. In one method, we assume, re, is a function of both temperature, T, and pressure, xV, and determine the five best-fit values of re. In the experiments, xV changes by a factor of more than two, but the standard deviation in the re values is 6%. In the second method, we assume re is a function only of T; and find that the value of re is not changed significantly. In all cases, the calculated nA(t) agree with the measurements. PMID- 27711595 TI - Density functional simulation of resonant inelastic X-ray scattering experiments in liquids: acetonitrile. AB - In this paper we report an experimental and computational study of liquid acetonitrile (H3C-C[triple bond, length as m-dash]N) by resonant inelastic X-ray scattering (RIXS) at the N K-edge. The experimental spectra exhibit clear signatures of the electronic structure of the valence states at the N site and incident-beam-polarization dependence is observed as well. Moreover, we find fine structure in the quasielastic line that is assigned to finite scattering duration and nuclear relaxation. We present a simple and light-to-evaluate model for the RIXS maps and analyze the experimental data using this model combined with ab initio molecular dynamics simulations. In addition to polarization-dependence and scattering-duration effects, we pinpoint the effects of different types of chemical bonding to the RIXS spectrum and conclude that the H2C-C[double bond, length as m-dash]NH isomer, suggested in the literature, does not exist in detectable quantities. We study solution effects on the scattering spectra with simulations in liquid and in vacuum. The presented model for RIXS proved to be light enough to allow phase-space-sampling and still accurate enough for identification of transition lines in physical chemistry research by RIXS.

AB - Stacking interactions between cyclohexane and benzene were studied in crystal structures from the Cambridge Structural Database and by ab initio calculations. Calculated at the very accurate CCSD(T)/CBS level of theory, the cyclohexane benzene interaction energy is -3.27 kcal mol-1, which is significantly stronger than the interaction in the benzene dimer (-2.84 kcal mol-1) indicating the importance of aliphatic-aromatic interactions. PMID- 27711597 TI - Coronene-based metal-organic framework: a theoretical exploration. AB - With the help of first-principle calculations we have proposed a new 2D metal organic framework (MOF) consisting of a -NH substituted coronene molecule and transition metals. Our study reveals that formation of such crystals is exothermic in nature, i.e. it is an energetically favourable process. The mode of magnetic coupling between the local magnetic moments and hence the overall magnetic moment of the MOF can be tuned by changing the transition metal. Not only the magnetic properties, but also the electronic structure of the MOF can be regulated from half-metal to spin-semiconductor to semimetallic-semiconductor by altering the metal center from Cr to Mn to Fe/Co. Our study also indicates that the change in the ligand structure and its anchoring group is also very effective in tuning the electronic properties of MOFs. The study of transport properties reveals that the half-metallic crystal possesses the maximum value of the spin filtering efficiency, i.e. 100%. PMID- 27711599 TI - Bidirectional particle transport and size selective sorting of Brownian particles in a flashing spatially periodic energy landscape. AB - We demonstrate a size sensitive experimental scheme which enables bidirectional transport and fractionation of paramagnetic colloids in a fluid medium. It is shown that two types of magnetic colloidal particles with different sizes can be simultaneously transported in opposite directions, when deposited above a stripe patterned ferrite garnet film subjected to a square-wave magnetic modulation. Due to their different sizes, the particles are located at distinct elevations above the surface, and they experience two different energy landscapes, generated by the modulated magnetic substrate. By combining theoretical arguments and numerical simulations, we reveal such energy landscapes, which fully explain the bidirectional transport mechanism. The proposed technique does not require pre imposed channel geometries such as in conventional microfluidics or lab-on-a-chip systems, and permits remote control over the particle motion, speed and trajectory, by using relatively low intense magnetic fields. PMID- 27711598 TI - Viscometry of single nanoliter-volume droplets using dynamic force spectroscopy. AB - The viscometry of minute amounts of liquid has been in high demand as a novel tool for medical diagnosis and biological assays. Various microrheological techniques have shown the capability to handle small volumes. However, as the liquid volume decreases down to nanoliter scale, increasingly dominant surface effects complicate the measurement and analysis, which remain a challenge in microrheology. Here, we demonstrate an atomic force microscope-based platform that determines the viscosity of single sessile drops of 1 nanoliter Newtonian fluids. We circumvent interfacial effects by measuring the negative-valued shear elasticity, originating from the retarded fluidic response inside the drop. Our measurement is independent of the liquid-boundary effects, and thus is valid without a priori knowledge of surface tension or contact angle, and consistently holds at a 1 milliliter-scale volume. Importantly, while previous methods typically need a much larger 'unrecoverable' volume above 1 microliter, our simple platform uses only ~1 nanoliter. Our results offer a quantitative and unambiguous methodology for viscosity measurements of extremely minute volumes of Newtonian liquids on the nanoliter scale. PMID- 27711600 TI - Solvothermal synthesis, stirring-assisted assembly and photoelectric performance of Te nanowires. AB - Tellurium nanowires (NWs) are attractive one-dimensional materials for many applications, yet most synthesis processes require hazardous chemical reducing agents and extreme operating conditions. Here we described a solvothermal synthesis of Te NWs using a non-toxic reducing agent, ascorbic acid. Then the Te NWs were assembled into a well-aligned film through a stirring-assisted oil-water air interface assembly method and a Te NWs photodetector was fabricated which is sensitive to infrared radiation. The photodetector based on the well-aligned Te NWs film had a series of more excellent photoelectric properties than that based on those being randomly oriented. For example, the photoresponsivity of the former is 103 times larger, and the response time is 1.15 * 103 times shorter, than those of the latter. PMID- 27711601 TI - Low energy electron catalyst: the electronic origin of catalytic strategies. AB - Using a low energy electron (LEE) as a catalyst, the electronic origin of the catalytic strategies corresponding to substrate selectivity, reaction specificity and reaction rate enhancement is investigated for a reversible unimolecular elementary reaction. An electronic energy complementarity between the catalyst and the substrate molecule is the origin of substrate selectivity and reaction specificity. The electronic energy complementarity is induced by tuning the electronic energy of the catalyst. The energy complementarity maximizes the binding forces between the catalyst and the molecule. Consequently, a new electronically metastable high-energy reactant state and a corresponding new low barrier reaction path are resonantly created for a specific reaction of the substrate through the formation of a catalyst-substrate transient adduct. The LEE catalysis also reveals a fundamental structure-energy correspondence in the formation of the catalyst-substrate transient adduct. Since the energy complementarities corresponding to the substrate molecules of the forward and the backward steps of the reversible reactions are not the same due to their structural differences, the LEE catalyst exhibits a unique one-way catalytic strategy, i.e., the LEE catalyst favors the reversible reaction more effectively in one direction. A characteristic stronger binding of the catalyst to the transition state of the reaction than in the initial reactant state and the final product state is the molecular origin of barrier lowering. PMID- 27711603 TI - The influence of mass-transport conditions on the ethanol oxidation reaction (EOR) mechanism of Pt/C electrocatalysts. AB - This study aims to provide further understanding of the influence of different parameters that control mass-transport (the revolution rate of the rotating disk electrode and the potential scan rate) on the ethanol oxidation reaction (EOR). The experiments were conducted on a home-made carbon-supported 20 wt% Pt/C electrocatalyst, synthesized using a modified polyol method, and characterized in terms of physicochemical properties by thermogravimetric analysis (TGA), powder X ray diffraction (XRD) and transmission electron microscopy (TEM). The EOR at the thin active layer of this electrocatalyst was characterized using both differential electrochemical mass spectrometry (DEMS) in a flow cell configuration and the rotating disc electrode (RDE). The results demonstrate that operating under stationary conditions (low scan rate and high RDE speed) hinders complete ethanol electrooxidation into CO2 and favors the poisoning of the electrocatalyst surface by hydroxide and strong ethanol adsorbates. As such, the EOR appears to be more efficient and faster under dynamic conditions than in near steady-state. PMID- 27711602 TI - Nuclear spin hyperpolarization with ansa-aminoboranes: a metal-free perspective for parahydrogen-induced polarization. AB - The parahydrogen-induced polarization (PHIP) phenomenon, observed when parahydrogen is used in H2 addition processes, provides a means for substantial NMR signal enhancements and mechanistic studies of chemical reactions. Commonly, noble metal complexes are used for parahydrogen activation, whereas metal-free activation is rare. Herein, we report a series of unimolecular metal-free frustrated Lewis pairs based on an ansa-aminoborane (AAB) moiety in the context of PHIP. These molecules, which have a "molecular tweezers" structure, differ in their substituents at the boryl site (-H, -Ph, -o-iPr-Ph, and -Mes). PHIP effects were observed for all the AABs after exposing their solutions to parahydrogen in a wide temperature range, and experimental measurements of their kinetic and thermodynamic parameters were performed. A theoretical analysis of their nuclear spin polarization effects is presented, and the roles of chemical exchange, chemical equilibrium and spin dynamics are discussed in terms of the key dimensionless parameters. The analysis allowed us to formulate the prerequisites for achieving strong polarization effects with AAB molecules, which can be applied for further design of efficient metal-free tweezers-like molecules for PHIP. Mechanistic (chemical and physical) aspects of the observed effects are discussed in detail. In addition, we performed quantum chemical calculations, which confirmed that the J-coupling between the parahydrogen-originated protons in AAB-H2 molecules is mediated through dihydrogen bonding. PMID- 27711604 TI - Bifurcated dissociative photoionization mechanism of acetic acid anhydride revealed by imaging photoelectron photoion coincidence spectroscopy. AB - The fragmentation processes of internal energy selected acetic acid anhydride cations, Ac2O+, were investigated by imaging photoelectron photoion coincidence (iPEPICO) spectroscopy. The first dissociation channel leads to the formation of CH3C(O)OCO+ (m/z = 87) by a CH3-loss. The 0 K appearance energy (E0) was determined to be 10.289 +/- 0.010 eV, in excellent agreement with the G4 calculated 10.28 eV transition state (TS) energy. Based on the thermochemical onset of CH3C(O)OCO+, a reverse barrier of 40 kJ mol-1 was found. The second dissociation channel leads to the formation of the acetyl cation, CH3CO+ (m/z = 43). The appearance of trace amounts of acetone in the mass spectra, statistical modeling of the branching ratios, and quantum chemical calculations point to the existence of a post-transition-state bifurcation on the potential energy surface and a single TS leading to multiple products. That is, at higher excess energies, the CH3-group may swerve back along an orbiting pathway to form the acetone cation by CO2-loss instead of leaving directly. The acetone cation thus formed is then energetic enough to lose a methyl group and yield the acetyl cation at a phenomenological E0 = 10.316 +/- 0.015 eV. The acetyl cation, which dominates the breakdown diagram up to 16 eV photon energy, is also formed by sequential CO2 loss from the CH3C(O)OCO+ intermediate at E0 = 10.53 +/- 0.03 eV. The CH3+ (m/z = 15) fragment ion appears above 13 eV photon energy. This species can be produced directly from the parent ion or via two sequential dissociation channels: by acetyl radical loss from the acetone cation or CO-loss from the acetyl cation.

AB - This Perspective addresses the use of coupled diabatic potential energy surfaces (PESs) together with rigorous quantum dynamics in full or reduced dimensional coordinate spaces to obtain accurate solutions to problems in nonadiabatic dynamics. A recently developed technique for obtaining the requisite diabatic PESs is reviewed. Three examples are considered in detail, two, H2O and NH3 photodissociation, are treated in the full dimensionality while for the third, phenol photodissociation, a reduced dimensionality treatment is used. In all three examples, nonadiabatic dynamics is dominated by conical intersections, near which the Born-Oppenheimer approximation fails. The role of the conical intersection induced geometric phase in the adiabatic representation, as evinced by the molecular Aharonov-Bohm effect, is discussed.

AB - The sequence of phase transitions and structural instabilities of the Sr2MWO6 double perovskites are investigated using a rigid ion model. The parametrization of the short range empirical potential allows the control of the cation sizes by means of independent parameters, and in particular, the effective size of the M cation can be tuned to reproduce the behaviour of the whole family. The coupling of symmetry modes and its role in the stability of the phases are discussed, and molecular dynamics simulations are carried out to determine structural phase transitions as a function of temperature. A satisfactory agreement between experiments and ab initio calculations is obtained for the relevant range of ionic radii and temperatures, indicating that the range of stability of the structures is mainly governed by steric effects.

AB - The structure-property relationships of bulk CeO2 and Ce2O3 have been investigated using AM05 and PBEsol exchange-correlation functionals within the frameworks of Hubbard-corrected density functional theory (DFT+U) and density functional perturbation theory (DFPT+U). Compared with conventional PBE+U, RPBE+U, PW91+U and LDA+U functionals, AM05+U and PBEsol+U describe experimental crystalline parameters and properties of CeO2 and Ce2O3 with superior accuracy, especially when +U is chosen close to its value derived by the linear-response approach. The present findings call for a reexamination of some of the problematic oxide materials featuring strong f- and d-electron correlation using AM05+U and PBEsol+U.

AB - Most of the pristine graphene-like two-dimensional materials have been found to be non-magnetic, and the emergence of magnetism usually needs an external electric field, substrate, strain, vacancy, or doping, which is not easily controlled in an experiment, limiting the potential applications in spintronics. Very recently, layered transition-metal dinitrides were explored experimentally and theoretically, and a pristine YN2 monolayer was predicted to be a half metallic ferromagnet with a graphene-like structure. To demonstrate the possible spintronic applications, herein, we designed spintronic devices based on the half metallic YN2 monolayer, and found perfect dual spin filtering and dual spin diode effects when a bias voltage was applied. Moreover, the devices also exhibited excellent spin Seebeck effects under a temperature gradient, which make the YN2 monolayer a promising candidate for both spintronic and spin caloritronic applications. These peculiar spin transport properties were analyzed and explained from the calculated spin-resolved band structure and transmission spectrum based on first-principles combined with the non-equilibrium Green's function method.

AB - For more than half a century, the phenomenon of pi-pi stacking has attracted much attention in several research fronts including materials science, chemical synthesis, and even drug design. Despite intense theoretical and experimental exploration, no unified description of the factors contributing to pi-pi stacking interactions and their weak bonding process has been proposed. In this work, based on calculations of the simplest prototype of pi-pi stacking, namely the benzene sandwich dimer (together with benzene-phenol, toluene and benzonitrile) using the density functional theory with dispersion correction, previously rarely studied intermolecular orbital interaction is discussed in detail and shown to involve considerable hybridizations of some of the orbitals which make a large contribution to the total interaction energy. We now propose a unified model for the often nebulous pi-pi stacking process and its analogs: firstly when the two monomers are too far apart, the dispersion effect will play a dominant role in bringing them together, but when they are too close, Pauli repulsion will force them apart. Secondly, at the equilibrium distance, electrostatic interaction, Pauli repulsion, dispersion and intermolecular orbital interaction are all pronounced, with part of the molecular orbitals of the two monomers interacting with each other to form a weak intermolecular bond.

Despite the long history of experimental and theoretical studies, the structure of this material is still under intensive discussion. In this work, we have applied structure searching coupled with density functional theory methods to provide a multiphase description of this material at x = 0.4. We demonstrate that the permutational freedom of B-site cations leads to the stabilisation of a variety of local phases reflecting a relatively flat energy landscape of PZT. Using a set of predicted local phases we reproduce the experimental pair distribution function (PDF) profile with high accuracy. We introduce a complex multiphase picture of the structure of PZT and show that additional monoclinic and rhombohedral phases account for a better description of the experimental PDF profile. We propose that such a multiphase picture reflects the entropy reached in the sample during the preparation process. PMID- 27711611 TI - Do group 1 metal salts form deep eutectic solvents? AB - Mixtures of metal salts such as ZnCl2, AlCl3 and CrCl3.6H2O form eutectic mixtures with complexing agents, such as urea. The aim of this research was to see if alkali metal salts also formed eutectics in the same way. It is shown that only a limited number of sodium salts form homogeneous liquids at ambient temperatures and then only with glycerol. None of these mixtures showed eutectic behaviour but the liquids showed the physical properties similar to the group of mixtures classified as deep eutectic solvents. This study focussed on four sodium salts: NaBr, NaOAc, NaOAc.3H2O and Na2B4O7.10H2O. The ionic conductivity and viscosity of these salts with glycerol were studied, and it was found that unlike previous studies of quaternary ammonium salts with glycerol, where the salt decreased the viscosity, most of the sodium salts increased the viscosity. This suggests that sodium salts have a structure making effect on glycerol. This phenomenon is probably due to the high charge density of Na+, which coordinates to the glycerol. 1H and 23Na NMR diffusion and relaxation methods have been used to understand the molecular dynamics in the glycerol-salt mixtures, and probe the effect of water on some of these systems. The results reveal a complex dynamic behaviour of the different species within these liquids. Generally, the translational dynamics of the 1H species, probed by means of PFG NMR diffusion coefficients, is in line with the viscosity of these liquids. However, 1H and 23Na T1 relaxation measurements suggest that the Na-containing species also play a crucial role in the structure of the liquids.

AB - The stability and the electronic properties of new AB-stacking and moire bilayer graphene superlattices with closed edge nanoholes are studied using DFT calculations. The closing of the edges is made of C-C bonds that form after folding the borders of the holes. Superlattices with periodic hexagonal symmetry are considered in more detail. The electronic band structure of the nanomeshes has metallic to semiconductor characteristics, depending not only on the size of the holes and the distance between them, but also on the hole shape. Bilayered graphene is considered as a platform for the engineering of nanostructures with folded edge holes. PMID- 27711613 TI - Improvement in surface-enhanced Raman spectroscopy from cubic SiC semiconductor nanowhiskers by adjustment of energy levels. AB - Enhanced reproducible Raman signals of the 4-MBA molecule were observed on the surface of semiconducting SiC nanowhiskers (SiCNWs) by surface-enhanced Raman spectroscopy (SERS). The SERS enhancement was further tuned and boosted by doping with B. Theoretical calculations were performed to unravel the mechanism of the SERS enhancement and it was found that the SERS effect was strongly associated with the energy level structure between the substrate and analyte. Appropriate energy level matching facilitated the charge transfer process during laser illumination, enhancing the SERS signal. This proposed mechanism was verified through multiple control experiments. PMID- 27711614 TI - Temperature- and pressure-dependent studies of niccolite-type formate frameworks of [NH3(CH2)4NH3][M2(HCOO)6] (M = Zn, Co, Fe). AB - We report temperature-dependent electric, IR and Raman studies of niccolite-type formate frameworks templated by protonated 1,4-diaminobutane. Our results show that the zinc-analogue exhibits a first-order phase transition close to 240 K. Single-crystal dielectric data show a much stronger anomaly at the phase transition for epsilon' along the a-direction compared to the c-direction. They also reveal that dipole relaxation exists in bnZn. Pronounced temperature dependence observed for bending and torsion modes of the NH3+ groups proves that ordering of protonated amine plays a major role in the phase transition mechanism. The ordering is associated with distortion of the zinc formate framework but the number of observed vibrational modes is much smaller than expected assuming 36-fold multiplication of the unit cell below TC. It is also much smaller than reported for the Mn-analogue, which exhibits only a two-fold increase of the unit cell below TC. We discuss the origin of this behavior. Our results also show that the Co-analogue exhibits a similar phase transition to its Zn-counterpart. However, the observed narrowing and splitting of the corresponding bands is significantly smaller, suggesting weaker distortion of the framework and the presence of some disorder for this compound even at 5 K. The Raman and IR spectra of the Fe-analogue show weak narrowing of bands upon cooling, indicative of statistical freezing of the protonated amine at low temperatures. We also report high-pressure Raman scattering studies of the zinc analogue. This study revealed a pressure-induced reversible phase transition between 3.4 and 4.1 GPa. Large shifts and splitting of modes corresponding to the vibrations of HCOO- ions associated with weak changes of the protonated amine prove that the major contribution to the phase transition mechanism comes from distortion of the zinc formate framework.

AB - Organometallic multiple-decker sandwich clusters are topics of great interest due to their unique electronic and magnetic properties originating from anisotropic structures. We report a joint anion photoelectron spectroscopic and computational study on a new family of manganese (Mn)-benzene (Bz) anionic clusters MnnBzn-. In stark contrast to the most widely studied vanadium-Bz sandwich clusters, it is found that MnnBzn- (n = 1-5) clusters exhibit unprecedented multiple-decker structures with a tilted Mn-Bz stacking and a monotonically increasing behavior of their high spin multiplicities. Furthermore, a couple of closed ring forms of Mn18Bz18- and its neutral state are computationally anticipated as an intriguing "cluster of Mn1Bz1 clusters" in which the neutral Mn18Bz18 has extremely high C18h symmetry with an uncommon spin state of 2S + 1 = 55. The extensively delocalized electron environment of Mn18Bz18 allows the simple Huckel model to reveal the strong intra-atomic exchange interactions within the Mn 3d electrons.

PMID- 27711617 TI - Investigation on the conversion of ethylene to ethylidyne on Pt(100) and Pd(100) using density functional theory. AB - The comprehensive formation network of ethylidyne (CH3C) from ethylene (CH2CH2) is investigated on Pt(100) and Pd(100) using the density functional theory method. The structural and energetic features of all intermediate products were considered. We found that the trend of the activation barriers in each pathway on Pt(100) and Pd(100) are the same, whereas the barriers on Pt(100) are higher than that on Pd(100). The activation barriers of 1,2-H shift reactions are relatively high compared with the other reactions. We screened three possible pathways and selected the optimal route as CH2CH2(ethylene) -> CH2CH(vinyl) -> CH2C(vinylidene) -> CH3C(ethylidyne). PMID- 27711618 TI - Structure-dependent vibrational dynamics of Mg(BH4)2 polymorphs probed with neutron vibrational spectroscopy and first-principles calculations. AB - The structure-dependent vibrational properties of different Mg(BH4)2 polymorphs (alpha, beta, gamma, and delta phases) were investigated with a combination of neutron vibrational spectroscopy (NVS) measurements and density functional theory (DFT) calculations, with emphasis placed on the effects of the local structure and orientation of the BH4- anions. DFT simulations closely match the neutron vibrational spectra. The main bands in the low-energy region (20-80 meV) are associated with the BH4- librational modes. The features in the intermediate energy region (80-120 meV) are attributed to overtones and combination bands arising from the lower-energy modes. The features in the high-energy region (120 200 meV) correspond to the BH4- symmetric and asymmetric bending vibrations, of which four peaks located at 140, 142, 160, and 172 meV are especially intense. There are noticeable intensity distribution variations in the vibrational bands for different polymorphs. This is explained by the differences in the spatial distribution of BH4- anions within various structures. An example of the possible identification of products after the hydrogenation of MgB2, using NVS measurements, is presented. These results provide fundamental insights of benefit to researchers currently studying these promising hydrogen-storage materials.

AB - The effect of chiral and achiral ligands protecting the inner Au9 core of the Au18(SR)14 cluster is studied based on density functional theory (DFT) and its corrected long-range interaction (DFT-D) approach. It was found that the electronic properties (energy levels) depend on the specific ligands, which induce distinct distortions on the Au-S framework. However, the substitution of S c-C6H11 as SCH3 ligands may be considered to be correct given the obtained resemblance to the displayed bonding, optical and chiroptical properties. A further comparison of the CD and UV spectra displayed by the Au18 cluster protected by chiral and achiral ligands attests that more intense profiles are featured by ligands including phenyl rings and/or oxygen atoms such that the Au18 cluster protected by either achiral meta-mercaptobenzoic acid (m-MBA) or achiral SPh ligands displays more intense UV and CD signals. These results provide new insight into the effect of ligands on thiolated gold clusters. PMID- 27711620 TI - In situ S-K XANES study of polymer electrolyte fuel cells: changes in the chemical states of sulfonic groups depending on humidity. AB - Changes in the chemical states of sulfonic groups of Nafion in polymer electrolyte fuel cells (PEFCs) under gas-flowing conditions were studied using in situ S-K XANES spectroscopy. The applied potential to the electrodes and the humidity of the cell were changed under flowing H2 gas in the anode and He gas in the cathode. While the potential shows no significant effect on the S-K XANES spectra, the humidity is found to induce reversible changes in the spectra. Comparison of the spectral changes with simulations based on the density functional theory calculations indicates that the humidity influences the chemical state of the sulfonic group; under wet conditions the sulfonic group is in the form of a sulfonate ion. By drying treatment the sulfonate ion binds to hydrogen and becomes sulfonic acid. Furthermore, a small fraction of the sulfonic acid irreversibly decomposes to atomic sulfur. The peak energy of the atomic sulfur suggests that the generated atomic sulfur is adsorbed on the Pt catalyst surfaces.

AB - Ceramics based on Sr0.8La0.067Ti0.8Nb0.2O3-delta have been prepared by the mixed oxide route. The La1/3NbO3 component generates ~13.4% A-site vacancies; this was fixed for all samples. Powders were sintered under air and reducing conditions at 1450 to 1700 K; products were of high density (>90% theoretical). Processing under reducing conditions led to the formation of a Ti1-xNbxO2-y second phase, core-shell structures and oxygen deficiency. X-ray diffraction (XRD) confirmed a simple cubic structure with space group Pm3[combining macron]m. Transmission electron microscopy revealed a high density of dislocations while analytical scanning transmission electron microscopy at atomic resolution demonstrated a uniform distribution of La, Nb and vacancies in the lattice. X-ray photoemission spectroscopy and thermogravimetry showed the oxygen deficiency (delta value) to be ~0.08 in reduced samples with enhanced carrier concentrations ~2 * 1021 cm-3. Both carrier concentration and carrier mobility increased with sintering time, giving a maximum figure of merit (ZT) of 0.25. Selective additional doping by La or Nb, with no additional A site vacancies, led to the creation of additional carriers and reduced electrical resistivity. Together these led to enhanced ZT values of 0.345 at 1000 K. The contributions from oxygen vacancies and charge carriers have been investigated independently. PMID- 27711622 TI - Elucidation of the local dynamics of domain-III of human serum albumin over the ps-MUs time regime using a new fluorescent label. AB - The ps-MUs dynamics of domain-III of human serum albumin (HSA) has been investigated using a new fluorescent marker selectively labeled to the Tyr-411 residue. The location of the marker has been confirmed using Forster resonance energy transfer (FRET) study. Steady state, time-resolved and single molecular level fluorescence techniques have been employed to understand the dynamics within the domain-III of HSA. It is found that solvent reorganization dynamics in domain-III is 1.7 times faster than that in domain-I. The timescale of the local rotational dynamics of domain-III is found to be 2.3 times faster than that of domain-I. Fluorescence correlation spectroscopic experiments reveal that domain III of HSA has more conformational flexibility than domain-I. Together, the results deliver useful details of the local environment around the domain-III of HSA, which have not been explored earlier, mainly because of a lack of a suitable fluorescent marker for domain-III. The newly synthesized probe serves well as a site specific fluorescent marker for HSA, and can be used for further investigation of the ligand binding properties and enzymatic activity of domain III of HSA.

AB - Histidine is a key component of a number of enzymatic mechanisms, and undertakes a myriad of functionalities in biochemical systems. Its computational modelling can be problematic, as its capacity to take on a number of distinct formal charge states, and tautomers thereof, is difficult to capture by conventional techniques. We demonstrate a means for recovering the experimental Raman optical activity (ROA) spectra of histidine to a high degree of accuracy. The resultant concordance between experiment and theory is of particular importance in characterising physically insightful quantities, such as band assignments. We introduce a novel conformer selection scheme that unambiguously parses snapshots from a molecular dynamics trajectory into a smaller conformational ensemble, suitable for reproducing experimental spectra. We show that the "dissimilarity" of the conformers within the resultant ensemble is maximised and representative of the physically relevant regions of molecular conformational space. In addition, we present a conformer optimisation strategy that significantly reduces the computational costs associated with alternative optimisation strategies. This conformer optimisation strategy yields spectra of equivalent quality to those of the aforementioned alternative optimisation strategies. Finally, we demonstrate that microsolvated models of small molecules yield spectra that are comparable in quality to those obtained from ab initio calculations involving a large number of solvent molecules. PMID- 27711624 TI - The photophysics of photoredox catalysis: a roadmap for catalyst design. AB - Recently, the use of transition metal based chromophores as photo-induced single electron transfer reagents in synthetic organic chemistry has opened up a wealth of possibilities for reinventing known reactions as well as creating new pathways to previously unattainable products. The workhorses for these efforts have been polypyridyl complexes of Ru(ii) and Ir(iii), compounds whose photophysics have been studied for decades within the inorganic community but never extensively applied to problems of interest to organic chemists. While the nexus of synthetic organic and physical-inorganic chemistries holds promise for tremendous new opportunities in both areas, a deeper appreciation of the underlying principles governing the excited-state reactivity of these charge-transfer chromophores is needed. In this Tutorial Review, we present a basic overview of the photophysics of this class of compounds with the goal of explaining the concepts, ground- and excited-state properties, as well as experimental protocols necessary to probe the kinetics and mechanisms of photo-induced electron and/or energy transfer processes.

AB - We investigate the electronic transport properties of four types of lateral graphene/h-BN nanoribbon heterojunctions using the non-equilibrium Green's function method in combination with the density functional theory. The results show that the heterojunction displays an interesting rectifying effect when the interface has a left-right type structure, while a pronounced negative differential resistance (NDR) effect when the interface has an up-down type structure. Moreover, when the interface of the heterojunction has a left-bank or right-bank type structure, it presents the rectifying (with a larger rectification ratio) and NDR effects. This work is helpful to further construct and prepare a nanodevice based on the graphene/h-BN heterojunction materials according to the proposed structures.

Their common one-dimensional structure can be extended into the second dimension to create conjugated planar sheets of covalently linked molecules. Extending pi-conjugation into the second dimension unlocks a new class of semiconductive polymers which as a consequence of their unique electronic properties can find usability in numerous applications. In this article the theoretical band structures of a set of conjugated 2D polymers are compared and information on the important characteristics band gap and valence/conduction band dispersion is extracted. The great variance in these characteristics within the investigated set suggests 2D polymers as exciting materials in which band structure engineering can be used to tailor sheet-like organic materials with desired electronic properties. PMID- 27711627 TI - Electrochemical oxidation of dihydronicotinamide adenine dinucleotide (NADH): comparison of highly oriented pyrolytic graphite (HOPG) and polycrystalline boron doped diamond (pBDD) electrodes. AB - The electro-oxidation of nicotinamide adenine dinucleotide (NADH) is studied at bare surfaces of highly oriented pyrolytic graphite (HOPG) and semi-metallic polycrystalline boron-doped diamond (pBDD). A comparison of these two carbon electrode materials is interesting because they possess broadly similar densities of electronic states that are much lower than most metal electrodes, but graphite has carbon sp2-hybridization, while in diamond the carbon is sp3-hybridised, with resulting major differences in bulk structure and surface termination. Using cyclic voltammetry (CV), it is shown that NADH oxidation is facile at HOPG surfaces but the reaction products tend to strongly adsorb, which causes rapid deactivation of the electrode activity. This is an important factor that needs to be taken into account when assessing HOPG and its intrinsic activity. It is also shown that NADH itself adsorbs at HOPG, a fact that has not been recognized previously, but has implications for understanding the mechanism of the electro oxidation process. Although pBDD was found to be less susceptible to surface fouling, pBDD is not immune to deterioration of the electrode response, and the reaction showed more sluggish kinetics on this electrode. Scanning electrochemical cell microscopy (SECCM) highlights a significant voltammetric variation in electroactivity between different crystal surface facets that are presented to solution with a pBDD electrode. The electroactivity of different grains correlates with the local dopant level, as visualized by field emission scanning electron microscopy. SECCM measurements further prove that the basal plane of HOPG has high activity towards NADH electro-oxidation. These new insights on NADH voltammetry are useful for the design of optimal carbon-based electrodes for NADH electroanalysis. PMID- 27711628 TI - Hydrogen bonding and delocalization in the ELF analysis approach. AB - Delocalization of the electron density in the proton donor fragment has been studied for 21 complexes, A-HB (A = F, Cl; B = Ne, Ar, CO2, N2, FH, ClH, H2O, PH3, NH3, Cl-, F-, covering the whole range of hydrogen bond strength. The proton donor and proton acceptor fragments are defined by a minimum variance principle achieved by the ELF partition. It is shown that the variance of the proton donor population as well as the charge transfer between the fragments calculated from the ELF partition is always smaller than that evaluated within the QTAIM framework. For both partition schemes, the variance and the charge transfer are correlated with the hydrogen bond strength. It is shown that the variance varies as the square root of the value of the ELF at the hydrogen bond interaction point (i.e. the saddle point at the boundary of the proton donor and proton acceptor moieties)etavv' providing a numerical proof of the conjecture that the ELF partition satisfies a minimum variance condition and an explanation of the success of the core valence bifurcation index as an indicator of the hydrogen bond strength. The ELF technique has been then applied to the study of hydrogen bonded crystals for which the variance of the fragment population has been estimated from etavv'. The systems investigated are KHF2, KDP and ice VIII. The results are consistent with very strong hydrogen bonds in the two former crystals and medium-weak bonding in ice. In ice VIII the variance, and therefore the hydrogen bond strength, increases with pressure yielding a phase transition toward ice X in which the hydrogen bond is characterized as very strong. Our study emphasizes the importance of the partition scheme which defines the proton donor fragment and the role of electron density delocalization between the fragments which is, according to us, often improperly termed as covalence.

AB - Searching for realistic materials able to realize room-temperature quantum spin Hall (QSH) effects is currently a growing field, especially when compatibility with the current group-IV electronics industry is required. Here we predict, through first-principles calculations, a new class of QSH phases in flattened germanene and stanene functionalized with X atoms (f-GeX2 and f-SnX2; X = H, F, Cl, Br, I) with a bulk gap as large as 0.56 eV, that can be tuned efficiently under mechanical strain. More interestingly, different from the normal band order in buckled germanane and stanane, the structural flatness leads to an inverted band order without spin-orbit coupling (SOC), whereas the SOC only opens the band gap. We also find that the characteristics of edge states, such as the Fermi velocity, are enhanced greatly by edge modification. When these films are deposited on a BN substrate, a nontrivial QSH state is preserved with a Dirac cone lying within the nontrivial band gap. These findings provide a promising platform for future realistic applications of the QSH effect at room temperature in two-dimensional group-IV films.

AB - A series of Ca9-x-yCe(PO4)7:xEu2+,yMn2+ phosphors were synthesized by a high temperature solid-state reaction method. The as-prepared samples were characterized by XRD and EDX measurements, which showed that Eu2+ and Mn2+ could be efficiently doped into the host. Ce3+ acts concurrently as activator and sensitizer in Ca9Ce(PO4)7, and the energy transfer mechanisms between Ce3+/Eu2+ and Ce3+/Mn2+ in Ca9Ce(PO4)7 were validated and proven to be a resonant type via dipole-quadrupole and dipole-dipole interactions, respectively. Besides, there is also energy transfer from Eu2+ to Mn2+ ions. The host, Ca9Ce(PO4)7, emits blue white light and Ca9Ce(PO4)7:xEu2+,yMn2+ phosphors emit blue-green through white to orange-red light under near-ultraviolet radiation as a result of tuning the ratio of Eu2+/Mn2+. Ca9Ce(PO4)7:0.04Eu2+,0.08Mn2+ emits white light with CIE coordinates (0.333, 0.310), a CCT of 5446 K, and a high CRI of 81. The energy transfer efficiency between Ce3+ and Mn2+ increases significantly with temperature. These results reveal that Ca9Ce(PO4)7:Eu2+,Mn2+ may be a potential candidate for white light-emitting phosphors.

AB - Mass transport processes of conjugated organic molecules (COMs) on inorganic surfaces are essential elements in thin film deposition for hybrid optoelectronic devices. Defects and in particular surface step-edges dictate the molecular nucleation and growth morphology, which itself determine many physical properties of the resulting hybrid interface. Here, we explore the detailed molecular kinetics and transport rates of a single physisorbed para-sexiphenyl (p-6P) molecule crossing a step-edge (a "hetero-Ehrlich-Schwoebel barrier") on the inorganic ZnO (101[combining macron]0) surface by a combination of all-atom molecular dynamics simulations and passage time theory. We determine temperature- and charge-dependent (free) energy landscapes, position-dependent diffusion coefficients, and ultimately the mean first passage time over the step-edges. We find two completely different step-edge crossing mechanisms, the occurrence and rates of which simultaneously depend on both electrostatic and thermal molecule surface coupling. In weakly coupled systems, the molecule crosses the step relatively quickly (in nanoseconds) by log-roll mechanisms while for strongly coupled systems, it crosses relatively slowly (in microseconds) in a strictly perpendicular fashion. In the latter process, "internal friction" from intramolecular bending and torsional degrees of freedom contribute a significant corrugation to the overall crossing barrier. Furthermore, we show that crossing pathways can also change qualitatively with step-edge height. The great complexity in hetero-barrier crossing of COMs (in contrast to simple atoms) revealed in this study has implications on the interpretation and possible control of nucleation and growth mechanisms at surface defects in hybrid systems.

AB - Chemical databases store information such as molecular formulas, chemical structures, and the physical and chemical properties of compounds. Although the massive databases of organic compounds exist, the search of target materials is constrained by a lack of physical and chemical properties necessary for specific applications. With increasing interest in the development of energy storage systems such as high-voltage rechargeable batteries, it is critical to find new electrolytes efficiently. Here we build a search map to screen organic additives and solvents with novel core and functional groups, and thus establish a database of electrolytes to identify the most promising electrolyte for high-voltage rechargeable batteries. This search map is generated from MAssive Molecular Map BUilder (MAMMBU) by combining a high-throughput quantum chemical simulation with an artificial neural network algorithm. MAMMBU is designed for predicting the oxidation and reduction potentials of organic compounds existing in the massive organic compound database, PubChem. We develop a search map composed of ~1 000 000 redox potentials and elucidate the quantitative relationship between the redox potentials and functional groups. Finally, we screen a quinoxaline compound for an anode additive and apply it to electrolytes and improve the capacity retention from 64.3% to 80.8% near 200 cycles for a lithium ion battery in experiments.

AB - SyPixD (Slr1694) is a blue-light receptor that contains a BLUF (blue-light sensor using a flavin chromophore) domain for the function of phototaxis. The key reaction of this protein is a light-induced conformational change and subsequent dissociation reaction from the decamer to the dimer. In this study, anomalous effects of pressure on this reaction were discovered, and changes in the compressibility of its short-lived intermediates were investigated. While the absorption spectra of the dark and light states are not sensitive to pressure, the formation yield of the first intermediate decreases with pressure to about 40% at 150 MPa. Upon blue-light illumination with a sufficiently strong intensity, the transient grating signal, which represents the dissociation of the SyPixD decamer, was observed at 0.1 MPa, and the signal intensity significantly decreased with increasing pressure. This behavior shows that the dissociation of the decamer from the second intermediate state is suppressed by pressure. However, while the decamer undergoes no dissociation upon excitation of one monomer unit at 0.1 MPa, dissociation is gradually induced with increasing pressure. For solving this strange behavior, the compressibility changes of the intermediates were measured as a function of pressure at weak light intensity. Interestingly, the compressibility change was negative at low pressure, but became positive with increasing pressure. Because the compressibility is related to the volume fluctuation, this observation suggests that the driving force for this reaction is fluctuation of the protein. The relationship between the cavities at the interfaces of the monomer units and the reactivity was also discussed.

AB - A new fluorescent conjugate (PNBD) with a structure of D-pi-A was designed and synthesized, where the donor (D), the acceptor (A) and the bridge (pi) are naphthalyl, dicyanovinyl and phenylethynyl-phenylethynyl, respectively. To improve the solubility of the conjugate, two long alkyl chains were introduced as substituents of the central aromatic ring. Spectroscopic studies demonstrated that PNBD is a strongly solvatochromic probe which is characterized by a large molar absorption coefficient (>32 000 cm-1 M-1), long wavelength absorption (>410 nm), large solvatochromic emission range (470-650 nm), high photochemical stability, and good solubility in common organic solvents. The fluorescent quantum yield of PNBD is limited in some polar solvents due to dual emission, a phenomenon ascribed to radiative decay from a higher excited singlet state. To eliminate dual emission, a covalently bound dimer (BPNBD) of PNBD characterized by weak vibronic coupling, was designed and synthesized. The dimer constituents are linked by a single bond between the naphthalyl moieties of the two PNBD monomers. As expected, BPNBD maintains almost all the strong points of the monomer, exhibits a substantial increase in fluorescence quantum yield, and eliminates dual emission by facilitating efficient internal conversion. Importantly, the use of PNBD and BPNBD in concert provides unprecedented discrimination among solvents of similar structures, such as (CH2Cl2, CHCl3, CCl4), (ethyl ether, THF, dioxane), or (methanol, ethanol, n-propanol, n-butanol, n-pentanol, n-hexanol, n-heptanol, n-octanol, n-decanol), allowing rapid and selective visual identification.

AB - The influence of the mass in the photodissociation dynamics of a homonuclear diatomic molecule (X2), embedded in a superfluid helium nanodroplet (T = 0.37 K) of 300 atoms, has been investigated using a hybrid quantum dynamics method recently proposed by us. Several hypothetical isotopic variants of Cl2 have been examined in order to make possible the analysis of a wide diversity of masses (mX: 0.25mCl-1.50mCl). This is probably the first time that this problem has been considered theoretically. The photodissociation mechanism of X2(B) is very similar to that of Cl2(B) and the efficiency of the X2-helium energy exchange mechanism can be so great that it leads to the full and partial (~86%) geminate recombination for the lower masses explored (mX = 0.25mCl and 0.50mCl, respectively). From the energy exchange perspective two dynamic regimes have been identified. The first regime occurs at the initial times of the photodissociation and corresponds to a perfectly inelastic collision (IC) between the atomic fragments (X) and some helium atoms of the solvation shell. The second regime occurs when the atomic fragments are moving through the nanodroplet, which behaves as a viscous fluid (VF). The ICVF mechanism has probably general character in the photodissociation of molecules embedded in superfluid helium nanodroplets.

AB - Organic transformations that involve direct functionalization of C-H bonds represent an attractive synthetic strategy that maximizes atom- and step-economy. With the generally high stability of C-H bonds, these processes have mostly required harsh reaction conditions, in combination with the necessity of activation of the C-H substrates and/or the coupling partners. As a class of activated coupling partners, strained or reactive rings exhibited high activity in the coupling with aryl and alkyl C-H bonds. Such a high reactivity of the rings allowed the facile construction of various new structural platforms via coupling with scission of the ring structures. The combination of C-H activation and scission of the rings allowed for applications of a broader scope of C-H bonds, including those less reactive alkyl ones. This synthetic diversity of these rings has been realized owing to the intrinsically different mechanisms of the interactions of transition metal catalysts and the strained/reactive rings.

AB - The metallic cyanoacetylides CuCCCN, AgCCCN, and AuCCCN have been synthesized in the throat of a pulsed supersonic expansion by reaction of metal vapors, produced by laser ablation, and BrCCCN. Their pure rotational spectra in the (X1Sigma+) electronic ground state were observed by Fourier transform microwave spectroscopy in the 2-10 GHz frequency region. Importantly, the rotational spectroscopy constants determined from the analysis of the rotational spectra clearly established the existence of metal-CCCN arrangements for all the mentioned cyanoacetylides. A study of the chemical bonding by means of a topological analysis of the electron density helps to understand the preference for metal-C bonding over metal-N bonding. PMID- 27711638 TI - Interfacial charge separation and photovoltaic efficiency in Fe(ii)-carbene sensitized solar cells. AB - The first combined theoretical and photovoltaic characterization of both homoleptic and heteroleptic Fe(ii)-carbene sensitized photoanodes in working dye sensitized solar cells (DSSCs) has been performed. Three new heteroleptic Fe(ii) NHC dye sensitizers have been synthesized, characterized and tested. Despite an improved interfacial charge separation in comparison to the homoleptic compounds, the heteroleptic complexes did not show boosted photovoltaic performances. The ab initio quantitative analysis of the interfacial electron and hole transfers and the measured photovoltaic data clearly evidenced fast recombination reactions for heteroleptics, even associated with un unfavorable directional electron flow, and hence slower injection rates, in the case of homoleptics. Notably, quantum mechanics calculations revealed that deprotonation of the not anchored carboxylic function in the homoleptic complex can effectively accelerate the electron injection rate and completely suppress the electron recombination to the oxidized dye. This result suggests that introduction of strong electron-donating substituents on the not-anchored carbene ligand in heteroleptic complexes, in such a way of mimicking the electronic effects of the carboxylate functionality, should yield markedly improved interfacial charge generation properties. The present results, providing for the first time a detailed understanding of the interfacial electron transfers and photovoltaic characterization in Fe(ii) carbene sensitized solar cells, open the way to a rational molecular engineering of efficient iron-based dyes for photoelectrochemical applications. PMID- 27711639 TI - Calculations of the light absorption spectra of porphyrinoid chromophores for dye sensitized solar cells. AB - Solar power is a strong alternative to the currently used fossil fuels in order to satisfy the world's energy needs. Among them, dye-sensitized solar cells (DSSC) represent a low-cost option. Efficient and cheap dyes are currently needed to make DSSCs competitive. Computational chemistry can be used to guide the design of new light-absorbing chromophores. Here, we have computationally studied the lowest excited states of ZnPBAT, which is a recently synthesized porphyrinoid chromophore with high light-absorption efficiency. The calculations have been performed at ab initio correlated levels of theory employing second-order coupled clusters (CC2) and algebraic diagrammatic construction using second order (ADC(2)) methods and by performing density functional theory (DFT) calculations using the time-dependent DFT (TDDFT) approach for excitation energies. The ultraviolet-visible (UV-vis) spectrum calculated at the ADC(2) and CC2 levels agrees well with the experimental one. The calculations show that ZnPBAT has six electronic transitions in the visible range of the absorption spectrum. The ab initio correlated calculations and previously reported experimental data have been used to assess the performance of several well-known density functionals that have been employed in the present TDDFT study. Solvent effects have been estimated by using the conductor-like screening model (COSMO). The influence of the addition of a TiO2 cluster to the chromophore systems has also been investigated. The results indicate that both CAM-B3LYP and Becke's "half-and half" (BHLYP) density functionals are appropriate for the studies of excitation energies in the blue range of the visible spectrum for these kinds of porphyrinoid chromophores, whereas the excitation energies of the Q band calculated at the ab initio correlated level are more accurate than those obtained in the present TDDFT calculations. The inclusion of solvent effects has a modest influence on the spectrum of the protonated form of the studied chromophores, whereas solvent models are crucial when studying the absorption spectrum of the anionic chromophore. The calculated UV-vis spectrum for the chromophore anion is not significantly affected by attaching a TiO2 cluster to it.

AB - Within an attempt to unravel the conundrum of irregular bandgap variations in hybrids of white-graphene (hBN) and graphene (G) observed in both experiment and theory, strong proofs about the decisive role of aromaticity in their electronic properties are brought to light. Sound numerical experiments conducted on zero-, one- and two-dimensional hBNG hybrids demonstrate that upon structural and/or electronic perturbation caused by foreign doping agents, the uniformity in local cyclic electron delocalization of ideal graphene restructures locally creating carbon hexagons of contrasting cyclic electron delocalization (c.c. local aromatic patterns) which may dominate the bandgap size of the resulting systems. In addition, relying on the quantum chemical aspect of aromaticity in terms of quantitative computations of cyclic electron delocalization together with pictorial intrinsic polarizability density representations, this work provides a solid and handy rule-of-thumb to be used in qualitative and intuitive predictions. According to this empirical rule, the origin of any nonmonotonic bandgap variation observed in stoichiometric 0D (BN)n/graphene hybrids with increasing hBN segment lies in instabilities caused by partially substituted benzenoid rings formed locally at the hBNG interfaces. This relationship, established in 0D graphene flakes and extended to 1D periodic ribbons, can be used to understand and qualitatively predict conflicting bandgap variations of vacancy-free 2D periodic lattices, pointing at the property of aromaticity as the missing link needed to solve the puzzle of conflicting bandgap variations in hBNG hybrids observed in experiment. PMID- 27711642 TI - Stress-strain behavior of block-copolymers and their nanocomposites filled with uniform or Janus nanoparticles under shear: a molecular dynamics simulation. AB - Although numerous research studies have been focused on studying the self assembled morphologies of block-copolymers (BCPs) and their nanocomposites, little attention has been directed to explore the relation between their ordered structures and the resulting mechanical properties. We adopt coarse-grained molecular dynamics simulation to study the influence of the morphologies on the stress-strain behavior of pure block copolymers and block copolymers filled with uniform or Janus nanoparticles (NPs). At first, we examine the effect of the arrangement (di-block, tri-block, alternating-block) and the components of the pure block copolymers, and by varying the component ratio between A and B blocks, spherical, cylindrical and lamellar phases are all formed, showing that spherical domains bring the largest reinforcing effect. Then by studying BCPs filled with NPs, the Janus NPs induce stronger bond orientation of polymer chains and greater mechanical properties than the uniform NPs, when these two kinds of NPs are both located in the interface region. Meanwhile, some other anisotropic Janus NPs, such as Janus rods and Janus sheets, are incorporated to examine the effect on the morphology and the stress-strain behavior. These findings deepen our understanding of the morphology-mechanics relation of BCPs and their nanocomposites, opening up a vast number of approaches such as designing the arrangement and components of BCPs, positioning uniform or Janus NPs with different shapes and shear flow to tailor their stress-strain performance.

AB - Excitons play a key role in technological applications since they have a strong influence on determining the efficiency of photovoltaic devices. Recently, it has been shown that the allotropes of phosphorus possess an optical band gap that can be tuned over a wide range of values including the near-infrared and visible spectra, which would make them promising candidates for optoelectronic applications. In this work we carry out ab initio many-body perturbation theory calculations to study the excitonic effects on the optical properties of two dimensional phosphorus allotropes: the case of blue and black monolayers. We elucidate the most relevant optical transitions, exciton binding energy spectrum as well as real-space exciton distribution, particularly focusing on the absorption spectrum dependence on the incident light polarization. In addition, based on our results, we use a set of effective hydrogenic models, in which the electron-hole Coulomb interaction is included to estimate exciton binding energies and radii. Our results show an excellent agreement between the many-body methodology and the effective models.

AB - The effect of Mg doping on the growth behavior and the electronic properties of aluminum clusters has been investigated theoretically using the CALYPSO (Crystal structure AnaLYsis by Particle Swarm Optimization) method in combination with density functional theory calculations. Compared to pure aluminum clusters, the structure of Mg-doped clusters shows the charming transformation with increasing atomic number. The photoelectron spectra (PES) of the global minima of anionic Aln and AlnMg (n = 3-20) clusters have been calculated based on the time dependent density functional theory (TD-DFT) method. The reliability of our theoretical methodology is easily corroborated by the good agreement between the experimental PES and the simulated spectra. Our findings bring forth an ionic bonding with enhanced stability for the Al6Mg cluster, paired with a surprisingly large HOMO-LUMO gap, as would be expected from the magic number of 20 valence electrons.

AB - With a combination of scanning tunneling microscopy and density functional theory, effects on molecular self-assembly involving two distinct chemical groups were investigated.

The viability of such a systematic approach to study self-assembled structures by considering the interplay between substrate effects and molecular design is demonstrated.

AB - An unusual linear dependency of viscosity with temperature has been observed in aqueous solutions of 1-octyl-3-methylimidazolium-based ionic liquids because of the ion induced structural transition which leads to the violation of both the Stokes-Einstein and fractional Stokes-Einstein equations, suggesting the presence of dynamic heterogeneity in the system. PMID- 27711647 TI - Interfacial properties of POPC/GDO liquid crystalline nanoparticles deposited on anionic and cationic silica surfaces. AB - Reversed lipid liquid crystalline nanoparticles (LCNPs) of the cubic micellar (I2) phase have high potential in drug delivery applications due to their ability to encapsulate both hydrophobic and hydrophilic drug molecules. Their interactions with various interfaces, and the consequences for the particle structure and integrity, are essential considerations in their effectiveness as drug delivery vehicles. Here, we have studied LCNPs formed of equal fractions of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine and glycerol dioleate in the presence of different fractions of the stabilizer Polysorbate 80. We have used a combination of ellipsometry, quartz crystal microbalance with dissipation monitoring and neutron reflectometry to reveal the structure and composition of the adsorbed layer on both anionic silica and cationic (aminopropyltriethoxysilane) silanized surfaces. For both types of surfaces, there is a spread near-surface layer comprising lipid and polymer as well as a sparse coverage of intact particles. The composition of the near-surface layer is very close to that of the particles, in contrast to the lipid bilayer observed with related systems. The interaction is stronger for cationic than anionic surfaces, which is rationalized in terms of the negative zeta potential of the LCNPs. The work shows that the attachment of and spreading from LCNPs is influenced by the properties of the surface, the internal structure, composition and stability of the particles as well as the nature of the stabilizer. PMID- 27711648 TI - Mechanistic insights into lithium ion battery electrolyte degradation - a quantitative NMR study. AB - The changes in electrolyte composition on the molecular level and the reaction mechanisms of electrolyte degradation upon thermal aging are monitored by quantitative NMR spectroscopy, revealing similar rates of degradation for pristine and already aged electrolytes. The data analysis is not in favor of an autocatalytic reaction mechanism based on OPF3 but rather indicates that the degradation of LiPF6 in carbonate based solvents proceeds via a complex sequence of "linear" reactions rather than a cyclic reaction pattern which is determined by the amount of water present in the samples. All investigated electrolytes are reasonably stable at temperatures of up to 60 degrees C in the presence of minor amounts or absence of water hence indicating that chemical instability of electrolyte components against water is decisive for degradation and an increase in temperature ("thermal aging") just accelerates the degradation impact of water. PMID- 27711649 TI - Probing the potential of halogen-free superhalogen anions as effective electrolytes of Li-ion batteries: a theoretical prospect from combined ab initio and DFT studies. AB - The potential of 23 superhalogen anions of halogen-free structures as high performance electrolytes of Li-ion batteries is theoretically explored here. According to high-level ab initio results at the CCSD(T) level, eight candidates, obeying the Wade-Mingos rule, should be capable of forming electrolytes, which are better than the currently used commercial products. When comparing different methods, MP2 was found to be in good agreement with CCSD(T) in the calculation of DeltaELi+ and DeltaEH2O, which are parameters describing the performance of potential electrolytes. Thus, MP2 represents a good choice for such calculations, particularly for large potential electrolyte systems wherein CCSD(T) calculations are actually impractical. The five functionals selected here (omegaB97XD, B2GP PLYP, B2K-PLYP, B2T-PLYP and B3LYP) are also capable of reproducing the variational trends of the relative values of different structures at the CCSD(T) level. However, the actual DFT values of DeltaELi+ are usually different from those of CCSD(T) by more than 1 eV. These significant deviations may be a problem when accurate DeltaELi+ values are required. PMID- 27711650 TI - Scaling of excitons in graphene nanodots. AB - The binding energy of an exciton in a semiconductor or an insulator is known to scale linearly with epsilonr-2, where epsilonr is its dielectric constant. In graphene however, since the kinetic energy scales linearly with the wave number instead of its square, the exciton binding energy is thus expected to scale with epsilonr-1. In this work we make use of the configuration interaction approach to study the properties of excitons in graphene nanodots embedded in various dielectric environments. With tens of million configurations taken into account in the calculation, we find that the exciton binding energy can be well described by a single scaling rule in which the scaling factor is found to vary with the dimension of the nanodots as well as with the on-site interaction parameter, which agrees well with a recent experiment. The linear relation of the exciton binding energy found with the quasi-particle gap also agrees with the previous work on bulk graphene and other two-dimensional materials.

AB - Fluorescence imaging is a powerful approach for noninvasive and real-time visualization and tracking of biomolecules and biological processes in living systems. The fluorescent chemosensors with dual/triple interplaying sensing mechanisms tend to provide diverse fluorescence signals or amplify the response signals, which are propitious to simultaneously track multiple analytes or to improve the selectivity and sensitivity of the chemosensors. Thus, the development of dual/triple sensing mechanism-based chemosensors has attracted great interest recently. This review highlights the representative cases of the fluorescent chemosensors with dual/triple interplaying sensing mechanisms published since 2010, and these chemosensors are classified according to the types of the interplaying sensing mechanisms, including ICT-FRET, PET-FRET, PET ICT-ESIPT, etc. PMID- 27711652 TI - Ethylene decomposition on Ir(111): initial path to graphene formation. AB - The complete mechanism behind the thermal decomposition of ethylene (C2H4) on Ir(111), which is the first step of graphene growth, is established for the first time employing a combination of experimental and theoretical methods. High resolution X-ray photoelectron spectroscopy was employed, along with calculations of core level binding-energies, to identify the surface species and their evolution as the surface temperature is increased. To understand the experimental results, we have developed a reaction sequence between the various CnHm species, from ethylene to C monomers and dimers, based on ab initio density functional calculations of all the energy barriers and the Arrhenius prefactors for the most important processes. The resulting temperature evolution of all species obtained from the simulated kinetics of ethylene decomposition agrees with photoemission measurements. The molecular dissociation mechanism begins with the dehydrogenation of ethylene to vinylidene (CH2C), which is then converted to acetylene (CHCH) by the removal and addition of an H atom. The C-C bond is then broken to form methylidyne (CH), and in the same temperature range a small amount of ethylidyne (CH3C) is produced. Finally methylidyne dehydrogenates to produce C monomers that are available for the early stage nucleation of the graphene islands. PMID- 27711653 TI - Tuning the structure and mechanical property of polymer nanocomposites by employing anisotropic nanoparticles as netpoints. AB - Introducing carbon nanotubes or graphene sheets into polymer matrices has received lots of scientific and technological attention. For the first time, we report a new kind of polymer nanocomposite (PNC) by means of employing anisotropic nanoparticles (NPs) as netpoints (referred to as an end-linked system), namely with NPs acting as netpoints to chemically connect the dual end groups of each polymer chain to form a network. By taking advantage of this strategy, the anisotropic NPs can be uniformly distributed in the polymer matrix, with the NPs being separated via the connected polymer chains. And the separation distance between NPs, the stress-strain behavior and the dynamic hysteresis loss (HL) can be manipulated by varying the temperature and the polymer chain flexibility. Meanwhile, the physically mixed system is investigated by changing the interaction strength between polymer and NPs, and the temperature. It is emphasized that compared to the physically mixed system, the end-linked system which employs carbon nanotubes or graphene as netpoints possesses good thermal stability because of its thermodynamically stable morphology, exhibiting both excellent static and dynamic mechanical properties. These results help us to design and fabricate high performance and multi-functional PNCs filled with carbon nanotubes or graphene, facilitating the potentially large industrial application of these nanomaterials.

AB - A CNNs/Ag/AgCl (defined as CNAAC) plasmonic photocatalyst with efficient photocatalytic degradation ability was obtained by depositing Ag/AgCl nanoparticles on g-C3N4 nanosheets (CNNS). Methyl orange (MO) and rhodamine B (RhB) were selected to evaluate the photocatalytic degradation performance of the as-synthesized CNAAC plasmonic photocatalysts. Among all of the prepared CNAAC plasmonic photocatalysts, CNAAC4 showed the most efficient photocatalytic degradation performance under visible light. Recycling experiments were also performed to confirm the superior stability of CNAAC4. The synergistic effect between the surface plasmon resonance effect (SPR) of the Ag nanoparticles and the steady heterojunction of CNNs-Ag/AgCl may mainly contribute to the enhanced photocatalytic activity and high stability of CNAAC. PMID- 27711655 TI - Shuttle inhibition by chemical adsorption of lithium polysulfides in B and N co doped graphene for Li-S batteries. AB - The advance of lithium sulfur batteries is now greatly restricted by the fast capacity fading induced by shuttle effect. Using first-principles calculations, various vacancies, N doping, and B,N co-doping in graphene sheets have been systematically explored for lithium polysufides entrapped in Li-S batteries. The LiS, LiC, LiN and SB bonds and Hirshfeld charges in the Li2S6 adsorbed defective graphene systems have been analyzed to understand the intrinsic mechanism of retaining lithium polysulfides in these systems. Total and local densities of states analyses elucidate the strongest adsorption sites among the N and B-N co doped graphene systems. The overall electrochemical performance of Li-S batteries varies with the types of defects in graphene. Among the defective graphene systems, only the reconstructed pyrrole-like vacancy is effective for retaining lithium polysulfides. N doping induces a strong LiN interaction in the defective graphene systems, in which the pyrrolic N rather than the pyridinic N plays a dominant role in trapping of lithium polysulfides. The shuttle effect can be further depressed via pyrrolic B,N co-doped defective graphene materials, especially the G-B-N-hex system with extremely strong adsorption of lithium polysulfides (4-5 eV), and simultaneous contribution from the strong LiN and SB interactions.

PMID- 27711657 TI - The origin of cooperative solubilisation by hydrotropes. AB - The signature of hydrotropic solubilisation is the sigmoidal solubility curve; when plotted against hydrotrope concentration, solubility increases suddenly after the minimum hydrotrope concentration (MHC), and reaches a plateau at higher hydrotrope concentrations. This sigmoidal curve is characteristic of cooperative phenomena, yet the true molecular basis of hydrotropic cooperativity has long remained unclear. Here we develop a theory, derived from the first principles of statistical thermodynamics using partially-open ensembles, to identify the origin of hydrophobic cooperativity. Our theory bears a close resemblance to the cooperative binding model used for protein-ligand binding. The cause of cooperativity is the enhancement of the hydrotrope m-body interaction induced by the presence of the solute; m can be estimated from the experimental solubility data.

AB - Soft lanthanide luminescent materials are impressive because of their tunable and self-assembling characteristics, which make them an attractive emerging materials field of research. In this report, novel luminescent lyotropic liquid crystals (LLCs) with four different mesophases have been fabricated by a protic ionic liquid (IL) based europium beta-diketonate complex EA[Eu(TTA)4] (EA = ethylammonium, TTA = 2-thenoyltrifluoro-acetone) and an amphiphilic block copolymer (Pluronic P123). The protic IL, ethylammonium nitrate (EAN), was used as both the solvent and linkage to stabilize the doped complexes. Analyses by single-crystal X-ray diffraction for EA[Eu(TTA)4] and Fourier transform infrared spectroscopy for the LLC materials reveal convincingly that the ethylammonium cations establish an effective connection with both the carbonyl group of the beta-diketonate ligand and the EO blocks of the amphiphilic block copolymer P123 via strong hydrogen bonding interactions. Due to this, an extremely long decay time of the excited state is obtained in EA[Eu(TTA)4] and excellent photostability of the luminescent LLCs could be achieved. The long-period ordered structures of the luminescent LLCs have been investigated by small-angle X-ray scattering measurements and the best luminescence performance was found in the most organized mesophase. Noteworthy, the LLCs could yield an effective confining effect on the europium complex accompanied by a sizeable elongation of the excited-state lifetime and an enhancement of the energy transfer efficiency, which reaches a remarkably high value of 52.6%. More importantly, the modulated luminescence properties observed in the four mesophase structures offer the potential and powerful possibility for these unique composite LLCs to be used in the fabrication of soft luminescent materials with tunable functions.

AB - The complexation behaviour of an imidazolium based ionic liquid surfactant (ILS) 3-methyl-1-dodecylimidazolium chloride, [C12mim][Cl], and its amide and ester functionalized counterparts 3-(2-(dodecylamino)-2-oxoethyl)-1-methyl-1H-imidazol 3-ium chloride, [C12Amim][Cl], and 3-methyl-1-dodecyloxycarbonylmethylimidazolium chloride, [C12Emim][Cl], with a model protein gelatin (G) in aqueous solution has been investigated. Complexation of G with ILSs at the air-solution interface has been monitored by tensiometry, whereas complexation and ILS mediated self assembly of G-ILS complexes in the bulk have been followed by dynamic light scattering (DLS), zeta-potential measurements, conductivity, and fluorescence techniques. The morphology of different self-assembled architectures has been monitored by scanning electron microscopy (SEM). Different transitions observed from various techniques in different concentration regimes of ILSs have been assigned to the varying extent of complexation and ILS mediated self-assembly of G-ILS complexes. The functionalization of the alkyl chain of the ILS [C12mim][Cl] with an amide ([C12Amim][Cl]) or ester ([C12Emim][Cl]) moiety owing to their additional hydrogen bonding (H-bonding) ability along with rigidity ([C12Amim][Cl]) or flexibility ([C12Emim][Cl]) near the imidazolium head group has been found to exert great influence on their complexation with G. This influence is fashioned as self-assembled structures of G-ILS complexes into discrete large hexagonal sheet-like or near spherical architectures, depending on the concentration and type of functionality of the alkyl chain of ILSs. The thermodynamic forces behind the complexation and self-assembly processes have been monitored by isothermal titration calorimetry (ITC) measurements and are discussed in detail. As both the nature of the ILS and protein (charge and structure) could affect their interactional behavior, the present results are expected to be very useful in deeply understanding the structure-property relationship between the nature of the ILS and proteins, which would be of great importance in the field of functional soft-materials.

AB - Dendrimers are arrays of coupled chromophores, where the energy of each unit depends on its structure and conformation. The light harvesting and energy funneling properties are strongly dependent on their highly branched conjugated architecture. Herein, the photoexcitation and subsequent ultrafast electronic energy relaxation and redistribution of a first generation dendrimer (1) are analyzed combining theoretical and experimental studies. Dendrimer 1 consists of three linear phenylene-ethynylene (PE) units, or branches, attached in the meta position to a central group opening up the possibility of inter-branch energy transfer. Excited state dynamics are explored using both time-resolved spectroscopy and non-adiabatic excited state molecular dynamics simulations. Our results indicate a subpicosecond loss of anisotropy due to an initial excitation into several states with different spatial localizations, followed by exciton self-trapping on different units. This exciton hops between branches. The absence of an energy gradient leads to an ultrafast energy redistribution among isoenergetic chromophore units. At long times we observe similar probabilities for each branch to retain significant contributions of the transition density of the lowest electronic excited-state. The observed unpolarized emission is attributed to the contraction of the electronic wavefunction onto a single branch with frequent interbranch hops, and not to its delocalization over the whole dendrimer.

AB - Carboxyl group modified zinc phthalocyanines (ZnPc) are classic and widely used photosensitizers (PSs) in upconversion nanoparticles (UCNPs) mediated photodynamic therapy (PDT) for tumor treatment. To improve the PDT activity of the complex system of ZnPc and UCNPs, many UCNPs with high red emission intensity were design and prepared. ZnPc-(COOH)4 tends to aggregate both in water and under physiological conditions, which can sharply decrease its PDT activity. Therefore, choosing monomeric COOH groups modified ZnPc as PSs is an alternative way to improve their activity. In this manuscript, three zinc(ii) phthalocyanines, substituted with 4 (ZnPc-(COOH)4), 8 (ZnPc-(COOH)8) and 16 (ZnPc-(COOH)16) COOH groups, were synthesized. A comparison of the results indicated that ZnPc (COOH)16 existed in its monomeric form under physiological conditions because of its large substituents. Moreover, ZnPc-(COOH)16 showed superior singlet oxygen (1O2) generation ability when compared to ZnPc-(COOH)4 and ZnPc-(COOH)8. Therefore, we chose ZnPc-(COOH)16 as PSs for absorption on the surface of the UCNPs. Then, they were encapsulated by crosslinked methacrylated hyaluronic acid (m-HA), which provides active tumor accumulation ability by binding its overexpressed receptors on the surface of cancer cells. The resulting nanoparticles can be effectively taken up by cancer cells and shows strong near infrared (NIR) light triggered PDT in vitro.

AB - In this contribution we show that it is possible to build accurate force fields for small organic molecules allowing the reliable reproduction of a large panel of bulk properties, which are seldom addressed in the same context. Starting from the results obtained in recent studies, we developed a protocol for charge estimation and virtual site generation for the amide class of molecules. The parametrization of electrostatic properties is based on population analysis and orbital localization of quantum mechanical computations rooted in density functional theory and the polarizable continuum model, without any additional external information. The new protocol, coupled to other recent studies in our group targeted at an accurate fitting of internal degrees of freedom, makes available a method for building force fields from scratch (excluding for the moment intermolecular van der Waals interactions) with focus on reproducing the structure and dynamics of hydrogen bonded liquids, yielding results that are in line or better than those delivered by current general force fields. The approach is tested on the demanding series formed by formamide and its two N-methyl derivatives, N-methylformamide and N,N-dimethylformamide. We show that the atomistic structure of the liquids arising from classical molecular dynamics (MD) simulations employing the new force field is in full agreement with X-ray and neutron diffraction experiments and the corresponding spatial distribution functions are in remarkable agreement with the results of ab initio MD simulations. It is noteworthy that the latter result has never been obtained before without using ad hoc (and system dependent) scale factors and that, in addition, our parameter-free procedure is able to reproduce static dielectric constants over a wide range of values without sacrificing the force field accuracy with respect to other observables. Finally, we are able to explain the trend of static dielectric constants followed by the three amides in terms of properties obtained from the simulations, namely hydrogen bond patterns and reorientational lifetimes.

AB - Transition metal spinel oxides have recently been suggested for the creation of efficient photovoltaic cells or photocatalysts. These compounds can be easily tuned by doping to adapt their electronic or magnetic properties. However, their cation distribution is very complex and band structures are still a subject of controversy. We propose a complete density functional theory investigation of MnxCo3-xO4 compounds, using different approximations in order to explain the variation of these properties as a function of composition (for 0 <= x <= 3) and determine the electronic structure over the whole solid solution range. A detailed study of their atomic structure, magnetic properties and electronic structure is given and compared with experimental data. The unit cell volume calculated for each composition is in agreement with the volume obtained experimentally in ceramics, while a cubic-to-tetragonal structural transition is predicted at x = 2.0. An antiferromagnetic to ferrimagnetic behavior is observed at the lowest ordering temperature depending on the composition. The band gap, deduced from our band structure calculations, strongly decreases upon doping of the end members Co3O4 and Mn3O4, but is partly restored by the tetragonal distortion. A direct band gap, close to 0.5-0.8 eV, is calculated for 0.25 <= x <= 2.25, justified by inter-metal transitions from Mn ions on octahedral sites.

AB - This paper discusses the fundamental features of the dielectric-dependent screened exchange potential approach for organic molecules and photocell materials. The energy difference (gap) between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) is a key factor when designing organic photocell materials. The magnitude of this energy gap strongly depends on the ratio of the Hartree-Fock (HF) exchange term combined with hybrid density functional theory (DFT) functionals. In ordinary hybrid DFT functionals, the HF exchange term ratio is often determined empirically and a constant value is employed for all materials. Conversely, the dielectric dependent exchange potential approach employs a system-dependent value for this parameter, which is proportional to the inverse of the dielectric constant. The organic materials examined in this paper take different dielectric constant values according to their material types and unit lengths; therefore, their HF exchange ratios are also different. This paper discusses the relationship between the energy gaps, the dielectric constants, and the HF exchange ratios in the dielectric-dependent screened exchange potential approach. For a series of acene type compounds, it was found that the HOMO-LUMO gap decreased when their conjugation systems are extended. The dielectric-dependent screened exchange potential approach demonstrated that the values of the dielectric constants of the compounds increased; consequently, the HF exchange ratio decreased. Similar results were obtained for a series of thiophene-based donor molecules. The calculated values were compared with those obtained via experimental measurements. We found that although the theoretical calculations of the HOMO LUMO gap usually overestimate experimental optical gaps, a better agreement between the experimental and calculated values can be obtained if we correct for the exciton binding energy.

AB - Crown ethers, discovered by the winner of the Nobel Prize Charles Pedersen, are cyclic chemical compounds that consist of a ring or multiple rings containing several ether groups that are capable of binding alkali ions. A smart fluorescent probe containing a crown ether moiety could be developed as a sensor for metal ions, anions and other bio-molecules and be further applied to monitor the relevant biological process in vivo. This review highlights recent advances which can be divided into seven parts: (i) fluorescent probes containing a simple crown ether or an aza-crown ether structure; (ii) fluorescent probes containing an azathia crown ether; (iii) fluorescent probes containing a cryptand; (iv) fluorescent probes containing two or more binding sites; (v) crown ether derivatives-metal complex assisted chemosensing of bioactive species; (vi) crown ether-based chemosensors for bioactive molecular detection; and (vii) efforts to improve biological relevance. PMID- 27711666 TI - Distinctive electron transport on pyridine-linked molecular junctions with narrow monolayer graphene nanoribbon electrodes compared with metal electrodes and graphene electrodes. AB - The electrodes in the molecular devices are essential for creating functional organic electronic devices. We investigate theoretically the pyridine-terminated molecule - 4,4'-bipyridyl attached to the narrow monolayer zigzag graphene nanoribbon electrodes, compared to the metal (Au, Ag and Cu) and 2D graphene electrodes. Results show that this zigzag graphene nanoribbon-based junction shows excellent electron transport performances. It possesses great transmission at the fermi level due to the strongest delocalization of the electronic state. The coupling of the dominant molecular orbital to the ZGNR electrodes is much stronger than that to the metal electrodes due to a higher contributing proportion of PDOS on N atoms in the molecule at the fermi level. Also the molecular orbital couples more strongly to the ZGNR electrodes than the graphene electrodes because of a larger device density of state around the fermi level. Moreover, the different molecule-electrode coupling among these metal-based devices stems from the different proportion of density of d-states of the electrodes at the fermi level. In addition, the device with the narrow ZGNR electrodes exhibits the NDR effect unexpectedly. PMID- 27711667 TI - Gels with sense: supramolecular materials that respond to heat, light and sound. AB - Advances in the field of supramolecular chemistry have made it possible, in many situations, to reliably engineer soft materials to address a specific technological problem. Particularly exciting are "smart" gels that undergo reversible physical changes on exposure to remote, non-invasive environmental stimuli. This review explores the development of gels which are transformed by heat, light and ultrasound, as well as other mechanical inputs, applied voltages and magnetic fields. Focusing on small-molecule gelators, but with reference to organic polymers and metal-organic systems, we examine how the structures of gelator assemblies influence the physical and chemical mechanisms leading to thermo-, photo- and mechano-switchable behaviour. In addition, we evaluate how the unique and versatile properties of smart materials may be exploited in a wide range of applications, including catalysis, crystal growth, ion sensing, drug delivery, data storage and biomaterial replacement. PMID- 27711669 TI - Adsorption dynamics and rate assessment of volatile organic compounds in active carbon. AB - In this paper, an investigation was presented about terahertz time-domain spectroscopy (THz-TDS) as a novel tool for the characterization of the dynamic adsorption rate of volatile organic compounds, including isooctane, ethanol, and butyl acetate, in the pores of active carbon. The THz-TDS peak intensity (EP) was extracted and corresponded to the measurement time frames. By analyzing EP with time, the entire process could be divided into three physical parts including volatilization, adsorption and stabilization so that the adsorption dynamics could be clearly identified. In addition, based on the pseudo-second-order kinetic model and the relationship between EP and time in the adsorption process, a mathematical model was built in terms of the adsorbed rate parameter and the THz parameter. Consequently, the adsorption rate of isooctane, ethanol, and butyl acetate could be assessed by the THz measurement, indicating that THz spectroscopy could be used as a promising selection tool to monitor the adsorption dynamics and evaluate adsorption efficiency in the recovery of pollutants. PMID- 27711670 TI - Direct simulation of electron transfer in the cobalt hexammine(ii/iii) self exchange reaction. AB - We present an atomistic simulation of the cobalt hexammine(ii/iii) self-exchange reaction using path integral (PI) methods. We construct a simple force field for the system in its reactant state that includes parameters for both atom-atom interactions, and interactions with an explicit transferring electron represented in the PI framework. We then calculate the outer sphere free energy barrier due to solvent reorganization from a PI molecular dynamics simulation and we obtain the dynamic transmission coefficient using ring polymer molecular dynamics. Combining these calculated values with literature values for the inner sphere reorganization energy, we obtain a reaction rate in good agreement with experimental measurements. The protocol introduced here circumvents the need for complex, system-specific force field parameterization along an assumed reaction coordinate making it sufficiently accurate, efficient, and broadly applicable to the study of both adiabatic and nonadiabatic charge transfer reactions in transition metal complexes. PMID- 27711668 TI - Synthesis, characterization, biological activity, DNA and BSA binding study: novel copper(ii) complexes with 2-hydroxy-4-aryl-4-oxo-2-butenoate. AB - A serie of novel square pyramidal copper(ii) complexes [Cu(L)2H2O] (3a-d) with O,O-bidentate ligands [L = ethyl-2-hydroxy-4-aryl-4-oxo-2-butenoate; aryl = 3 methoxyphenyl-2a, (E)-2-phenylvinyl-2b, (E)-2-(4'-hydroxy-3'-methoxyphenyl)vinyl 2c, 3-nitrophenyl-2d, 2-thienyl-2e] were synthesized and characterized by spectral (UV-Vis, IR, ESI-MS and EPR), elemental and X-ray analysis. The antimicrobial activity was estimated by the determination of the minimal inhibitory concentration (MIC) using the broth microdilution method. The most active antibacterial compounds were 3c and 3d, while the best antifungal activity was showed by complexes 3b and 3e. The lowest MIC value (0.048 mg mL-1) was measured for 3c against Proteus mirabilis. The cytotoxic activity was tested using the MTT method on human epithelial carcinoma HeLa cells, human lung carcinoma A549 cells and human colon carcinoma LS174 cells. All complexes showed extremely better cytotoxic activity compared to cisplatin at all tested concentrations. Compound 3d expressed the best activity against all tested cell lines with IC50 values ranging from 7.45 to 7.91 MUg mL-1. The type of cell death and the impact on the cell cycle for 3d and 3e were evaluated by flow cytometry. Both compounds induced apoptosis and S phase cell cycle arrest. The interactions between selected complexes (3d and 3e) and CT-DNA or bovine serum albumin (BSA) were investigated by the fluorescence spectroscopic method. Competitive experiments with ethidium bromide (EB) indicated that 3d and 3e have a propensity to displace EB from the EB-DNA complex through intercalation suggesting strong competition with EB [Ksv = (1.4 +/- 0.2) and (2.9 +/- 0.1) * 104 M-1, respectively]. Ksv values indicate that these complexes bind to DNA covalently and non-covalently. The achieved results in the fluorescence titration of BSA with 3d and 3e [Ka = (2.9 +/- 0.2) * 106 and (2.5 +/- 0.2) * 105 M, respectively] showed that the fluorescence quenching of BSA is a result of the formation of the 3d- and 3e-BSA complexes. The obtained Ka values are high enough to ensure that a significant amount of 3d and 3e gets transported and distributed through the cells. PMID- 27711671 TI - Axial coordination and electronic structure of diatomic NO, CO, and O2 molecules adsorbed onto Co-tetraphenylporphyrin on Au(111), Ag(111), and Cu(111): a density functional theory study. AB - Based on density functional theory calculations, we investigated the axial bindings of diatomic molecules (NO, CO, and O2) to metalloporphyrins and their spin switching behaviors. These binding reactions provide the ways to control molecular states and spins in metalloporphyrin systems that can be used in bio sensing and spintronic applications. To microscopically understand the non trivial axial binding structures and spin-switching behaviors of diatomic molecules (NO, CO, and O2) adsorbed onto Co-tetraphenylporphyrin (CoTPP), we performed spin-polarized density functional theory (DFT) calculations for various CoTPP systems on Au(111), Ag(111), and Cu(111) substrates. We also systematically evaluated the effects of van der Waals and Hubbard U corrections by directly comparing the electronic structure with the results of scanning tunnelling microscopy. From the calculation results, we have found that a NO molecule, almost 60 degrees tilted away from the axial direction, is coordinated with CoTPP with a binding energy of 1.2-1.7 eV depending on substrates, and the spin state of CoTPP is completely switched off due to the charge transfer from NO to CoTPP. On the other hand, CO and O2 molecules rather weakly interact with a binding energy of 0.4-0.8 eV, and a spin polarization of ~1MUB is still present at CoTPP. A CO molecule is expected to be almost straightly coordinated along the axial direction of CoTPP, but O2 is tilted similarly to the NO case. Regarding the substrate effects, we have found that there is noticeable charge transfer from Ag(111) and Cu(111) to CoTPP, but no significant charge transfer from Au(111) to CoTPP. These findings of the axial coordination and spin states for NO, CO, and O2 adsorbed CoTPP systems will be useful for understanding bio sensing mechanisms and designing molecular spintronic systems.

AB - Two-photon excitation (TPE) nanoparticle-based photosensitizers (PSs) that combine the advantages of TPE and nanotechnology have emerged as attractive therapeutic agents for near-infrared red (NIR) light excited photodynamic therapy (PDT) for cancer treatment. TPE PDT is characterized by nonlinear absorption of two relatively low-energy photons of NIR light with the resulting emission of high-energy visible light. This high-energy light can sensitize oxygen to produce cytotoxic reactive oxygen species (ROS) and singlet oxygen (1O2) which can kill cancer cells. The long-wavelength light used to excite TPE NPs allows for deeper tissue penetration to achieve efficient PDT of deep-seated tumors. Moreover, TPE nanoparticles normally have large two-photon absorption (TPA) cross-sections, which hold great potential as efficient two-photon donors in PDT. In this review, we will summarize the recent advances made in the development of TPE nanoparticles for cancer PDT. Five different TPE nanoparticles, including quantum dots (QDs), carbon nanomaterials, silica nanoparticles, gold nanomaterials, and polymer nanoparticles, are summarized in detail, and the existing challenges as well as the future perspectives are also discussed. PMID- 27711674 TI - Structure and Li+ ion transport in a mixed carbonate/LiPF6 electrolyte near graphite electrode surfaces: a molecular dynamics study. AB - Electrolyte and electrode materials used in lithium-ion batteries have been studied separately to a great extent, however the structural and dynamical properties of the electrolyte-electrode interface still remain largely unexplored despite its critical role in governing battery performance. Using molecular dynamics simulations, we examine the structural reorganization of solvent molecules (cyclic ethylene carbonate : linear dimethyl carbonate 1 : 1 molar ratio doped with 1 M LiPF6) in the vicinity of graphite electrodes with varying surface charge densities (sigma). The interfacial structure is found to be sensitive to the molecular geometry and polarity of each solvent molecule as well as the surface structure and charge distribution of the negative electrode. We also evaluated the potential difference across the electrolyte-electrode interface, which exhibits a nearly linear variation with respect to sigma up until the onset of Li+ ion accumulation onto the graphite edges from the electrolyte. In addition, well-tempered metadynamics simulations are employed to predict the free-energy barriers to Li+ ion transport through the relatively dense interfacial layer, along with analysis of the Li+ solvation sheath structure. Quantitative analysis of the molecular arrangements at the electrolyte electrode interface will help better understand and describe electrolyte decomposition, especially in the early stages of solid-electrolyte-interphase (SEI) formation. Moreover, the computational framework presented in this work offers a means to explore the effects of solvent composition, electrode surface modification, and operating temperature on the interfacial structure and properties, which may further assist in efforts to engineer the electrolyte electrode interface leading to a SEI layer that optimizes battery performance. PMID- 27711673 TI - Metal-organic frameworks as competitive materials for non-linear optics. AB - The last five years have witnessed a huge breakthrough in the creation and the study of the properties of a new class of compounds - metamaterials. The next stage of this technological revolution will be the development of active, controllable, and non-linear metamaterials, surpassing natural media as platforms for optical data processing and quantum information applications. However, scientists are constantly faced with the need to find new methods that can ensure the formation of quantum and non-linear metamaterials with higher resolution. One such method of producing metamaterials in the future, which will provide scalability and availability, is chemical synthesis. Meanwhile, the chemical synthesis of organized 3D structures with a period of a few nanometers and a size of up to a few millimeters is not an easy task and is yet to be resolved. The most promising avenue seems to be the use of highly porous structures based on metal-organic frameworks that have demonstrated their unique properties in the field of non-linear optics (NLO) over the past three years. Thus, the aim of this review is to examine current progress and the possibilities of using metal organic frameworks in the field of non-linear optics as chemically obtained metamaterials of the future. The review begins by presenting the theoretical principles of physical phenomena represented by mathematical descriptions for clarity. Major attention is paid to the second harmonic generation (SHG) effect. In this section we compare inorganic single crystals, which are most commonly used to study the effect in question, to organic materials, which also possess the required properties. Based on these data, we present a rationale for the possibility of studying the non-linear optical properties of metal-organic structures as well as describing the use of synthetic approaches and the difficulties associated with them. The second part of the review explicitly acquaints the reader with a new class of materials which successfully combines the positive properties of organic and inorganic materials. Using recently synthesized metal-organic frameworks and coordination polymers in the field of non-linear optics as an example, we consider synthetic approaches used for obtaining materials with desired properties and the factors to be considered in this case. Finally, probable trends towards improving the quality of the synthesized materials with regards to their further use in the field of non linear optical effects are described. PMID- 27711675 TI - Mobility and association of ions in aqueous solutions: the case of imidazolium based ionic liquids. AB - The mobility and the mechanism of ion pairing of 1,1 electrolytes in aqueous solutions were investigated systematically on nine imidazolium based ionic liquids (ILs) from 1-methylimidazolium chloride, [MIM][Cl], to 1-dodecyl-3 methylimidazolium chloride, [1,3-DoMIM][Cl], with two isomers 1,2 dimethylimidazolium chloride, [1,2-MMIM][Cl], and 1,3-dimethylimidazolium chloride, [1,3-MMIM][Cl]. Molecular dynamics (MD) simulations, statistical mechanics calculations in the framework of the integral equation theory using one dimensional (1D-) and three-dimensional (3D-) reference interaction site model (RISM) approaches as well as conductivity measurements were applied. From experiment and MD simulations it was found that the mobility/diffusion coefficients of cations in the limit of infinite dilution decrease with an increasing length of the cation alkyl chain, but not linearly. The aggregation tendency of cations with long alkyl chains at higher IL concentrations impedes their diffusivity. Binding free energies of imidazolium cations with the chloride anion estimated by RISM calculations, MD simulations and experiments reveal that the association of investigated ILs as model 1,1 electrolytes in water solutions is weak but evidently dependent on the molecular structure (alkyl chain length), which also strongly affects the mobility of cations. PMID- 27711676 TI - Surface and shape modification of mackinawite (FeS) nanocrystals by cysteine adsorption: a first-principles DFT-D2 study. AB - The control of nanoparticle shape offers promise for improving catalytic activity and selectivity through optimization of the structure of the catalytically active site. Here, we have employed density functional theory calculations with a correction for the long-range interactions (DFT-D2) to investigate the effect of adsorption of the amino acid cysteine on the {001}, {011}, {100}, and {111} surfaces of mackinawite, which are commonly found in FeS nanoparticles. We have calculated the surface energies and adsorption energies for all the surfaces considered, and compared the surface energies of the pure and adsorbed systems. Based on the calculated surface energies, we have simulated the thermodynamic crystal morphology of the pure and cysteine-modified FeS nanoparticles using Wulff's construction. The strength of cysteine adsorption is found to be related to the stability of different surfaces, where it adsorbs most strongly onto the least stable FeS{111} surface via bidentate Fe-S and Fe-N chemical bonds and most weakly onto the most stable FeS{001} surface via hydrogen-bonded interactions; the adsorption energy decreases in the order {111} > {100} > {011} > {001}. We demonstrate that the stronger binding of the cysteine to the {011}, {100}, and {111} surfaces rather than to the {001} facet results in shape modulation of the FeS nanoparticles, with the reactive surfaces more expressed in the thermodynamic crystal morphology compared to the unmodified FeS crystals. Information regarding the structural parameters, electronic structures and vibrational frequency assignments of the cysteine-FeS complexes is also presented.

AB - The solid-state NMR spectra of many NMR active elements are often extremely broad due to the presence of chemical shift anisotropy (CSA) and/or the quadrupolar interaction (for nuclei with spin I > 1/2). These NMR interactions often give rise to wideline solid-state NMR spectra which can span hundreds of kHz or several MHz. Here we demonstrate that by using fast MAS, proton detection and dipolar hetero-nuclear multiple-quantum (D-HMQC) pulse sequences, it is possible to rapidly acquire 2D spectra which correlate 1H chemical shifts to the indirectly detected wideline MAS powder patterns of dipolar coupled hetero nuclei. The D-HMQC pulse sequence enables broadband excitation of the wideline hetero-nuclear NMR spectrum and provides higher sensitivity by detecting the narrower and more sensitive 1H NMR signal. This approach is demonstrated for the rapid acquisition of 2D 1H detected 195Pt solid-state NMR spectra of cisplatin and transplatin and the 71Ga solid-state NMR spectrum of a self-assembled Ga coordination polymer of unconfirmed structure. This approach should be broadly applicable for the rapid acquisition of wideline MAS solid-state NMR spectra of moderately abundant NMR nuclei.

AB - The high-temperature/high-pressure treatment of the K-Te-U oxo-family at 1100 degrees C and 3.5 GPa results in the crystallization of a series of novel uranyl tellurium compounds, K2[(UO2)3(TeIVO3)4], K2[(UO2)TeO14], alpha-K2[(UO2)TeVIO5] and beta-K2[(UO2)TeVIO5]. In contrast to most of the reported uranyl compounds which are favorable in layered structures, we found that under extreme conditions, the potassium uranyl oxo-tellurium compounds preferably crystallized in three-dimensional (3D) framework structures with complex topologies. Anion topology analysis indicates that the 3D uranyl tellurite anionic framework observed in K2[(UO2)3(TeIVO3)4] is attributable to the additional linkages of TeO3 polyhedra connecting with TeO4 disphenoids from the neighboring U-Te layers. The structure of K2[(UO2)TeO14] can be described based on [UTe6O26]22- clusters, where six TeO5 polyhedra enclose a hexagonal cavity in which a UO8 polyhedron is located. The [UTe6O26]22- clusters are further linked by TeO5 square pyramids to form the 3D network. Similar to uranyl tellurates, both alpha-K2[(UO2)TeVIO5] and beta-K2[(UO2)TeVIO5] contain TeO6 octahedra which share a common face to form a dimeric Te2O10 unit. However, in alpha-K2[(UO2)TeVIO5], these Te2O10 units connect with UO6 tetragonal bipyramids to form a 3D structural framework, while in beta-K2[(UO2)TeVIO5], the same Te2O10 dimers are observed to link with UO7 pentagonal bipyramids, forming 2D layers. Raman measurements were carried out and the vibration bands related to TeIV-O, TeVI-O and UVI-O bonds are discussed.

AB - A one dimensional nanostructure array has been considered as a successful charge transport material for perovskite solar cells (PSCs), because of its large internal surface area, superior charge collection efficiency and fast charge transport. Herein we demonstrate a ZnO nanorod (NR) array as the electron collector in a hole-conductor-free PSC with a carbon counter electrode (CE). A relatively low initial power conversion efficiency (PCE) of 5.6% was achieved using a 1 MUm long ZnO NR array as an electron collector. However, by introduction of a thin TiO2 coating layer on the surface of ZnO via TiCl4 treatment, the PCE of the cell has been improved to the highest value of 8.24%. It is revealed that the performance enhancement of the ZnO/TiO2 NR based PSCs is largely attributed to the larger surface area, reduced electron combination, and superior electron transport properties.

AB - Epitaxial La0.67Ba0.33Ti0.02Mn0.98O3 (denoted as LBTMO hereafter) thin films of approximately 95 nm thickness were deposited by a pulsed laser deposition technique onto SrTiO3 (STO) (001) substrates. High-resolution X-ray diffraction (HRXRD) and transmission electron microscopy (TEM) investigations revealed that the films are epilayers with a four-fold symmetry around the [001] direction. Cross-sectional TEM and the presence of Pendellosung fringes in the XRD profiles demonstrate smooth interfaces. The STO substrate induces an in-plane compressive strain, which leads to a slight tetragonality of the film structure. The epilayers exhibit paramagnetic-to-ferromagnetic phase transitions at the Curie temperature TC (286 K), close to room temperature. The magnetization easy axis lies in the film plane along the [100] direction of the (001) substrate. The magnetic entropy change (DeltaSM) associated with the second-order magnetic phase transition was determined via magnetization measurements in the temperature range between 210 and 350 K under different magnetic fields. The relative cooling power (RCP) of this film is about 220 J kg-1, somewhat lower than that of bulk Gd (410 J kg-1) for a 50 kOe field change, making the LBTMO ferromagnetic thin films a promising candidate for micro/nanomagnetic refrigeration around room temperature. The proposed universal curve provides a simple method for extrapolating DeltaSM in a wide range of fields and temperatures, thus confirming the order of the magnetic transition in this system. The magnetic entropy (DeltaSM)max around TC is proportional to (MU0H/TC)2/3 in agreement with the mean-field theory, indicating the existence of long-range ferromagnetic interactions in epitaxial LBTMO thin films. PMID- 27711681 TI - Tunability of the two-dimensional electron gas at the LaAlO3/SrTiO3 interface by strain-induced ferroelectricity. AB - The two-dimensional electron gas (2DEG) formed at the interface between two insulating materials LaAlO3 (LAO) and SrTiO3 (STO) has recently generated a lot of interest. Here, based on first-principles density functional theory calculations, we investigate the existence and stability of the 2DEG under the application of a biaxial strain on the LAO/STO(001) heterostructure. The compressive strain induces ferroelectric (FE) polarization in STO, which allows for the tunability of the 2DEG by reversing the STO polarization orientation. We show that the formation of the 2DEG is unstable when LAO and STO have the same polarization direction. On the other hand, the 2DEG will always form if the two polarizations are in the opposite directions regardless of the LAO thickness, which is in contrast to the unstrained interface that has a critical thickness for stabilizing the 2DEG. We show that the underpinnings of this behavior are due to charge passivation and band gap alignment. PMID- 27711682 TI - Effects of chemical substitutions on the properties of azacalixphyrins: a first principles study. AB - Azacalixphyrins are particularly stable macrocycles absorbing light up to the near infrared region, which makes them good candidates for applications in a wide panel of fields. However, to date, only a very limited number of substituted azacalixphyrins are experimentally known. Herein, aiming to drive the synthesis towards the most promising substitution patterns, we explore with first principles approaches the impact of adding substituents on both the aromaticity and absorption spectrum of these macrocycles. Both neutral and dicationic species are considered. For the former, we show that the substituents have an impact on the relative stabilities of the different tautomers, which can lead to significant tuning of the properties. Depending on the electron donating or electron attracting character of the chemical groups added at the periphery, the first absorption band in the near infrared region can be remarkably red or blueshifted, respectively. Our calculations also predict that replacing the macrocycle phenyl rings with pyridine rings leads to a more planar structure - due to the reduction of the steric stress at the centre - and to more equalised bond lengths. This results in an increase of the aromatic strength of the macrocycle by ca. 20%, at the cost of a large blueshift of the first absorption band. Compared to the neutral forms, the latter dicationic species are found to be more aromatic. Flatter and therefore more aromatic macrocycles can also be obtained for the neutral species by replacing the peripheral NH2/NH groups with OH/O groups/atoms, owing to the interaction between the oxygen lone pairs and the vicinal hydrogen atom. It is found that the combination of nitrogenation and oxidation allows doubling the aromatic character strength compared to the parent compound. This work therefore paves the way to the control of the properties of azacalixphyrins by purpose-designed substitutions.

AB - We show that chirality transfer from chiral polyoxometalates to achiral polyoxometalates can occur in aqueous solution with unexpected selectivity of surrounding counterions. In comparison with sodium ions, protonated dimethylammonium counterions play a critical role in shortening the inter-cluster distance, thus promoting the efficiency of chirality transfer.

AB - Based on Cd(NO3)2.4H2O and 4,4'-((5-carboxy-1,3-phenylene)bis(oxy))dibenzoic acid (H3cpbda), two isomeric coordination polymers, {[Cd1.5(cpbda)(bpa)(H2O)2].1.5H2O}n (1), [Cd(H2cpbda)2(bpa)0.5(H2O)]n (2), were synthesized by using different solvent-systems. The complexes were characterized by single-crystal X-ray diffraction, IR spectroscopy, powder X-ray diffraction, and thermogravimetric analysis. Owing to the obvious structural difference between the two isomeric complexes, the further fluorescence sensing and dye selection and adsorption were investigated. The 3D tight stacking structure of 1 strengthened the fluorescence emission and the loose 2D layer structure of 2 generated the active selection and adsorption of the Malachite Green Oxalate (MGO) dye.

AB - 1-Octyl-3-methyl imidazolium halides ([OMIM]I and [OMIM]Cl) were loaded on top of CCl4, and an in situ inclusion process was monitored from the CCl4 phase as time elapses by infrared absorption spectroscopy. Absorption from the bands corresponding to the C(2)-H and C(4,5)-H stretch modes in the imidazolium cation was reduced significantly compared to the bulk IL spectra. This indicates that (1) the [OMIM] cation exists in CCl4 as a monomer, dissociated from the anion and other cations, and (2) hydrogen bonding between the anion and the cation increases the dipole strength of the CH moieties in the imidazolium ring. [OMIM]I was found to transfer into the CCl4 phase much faster than [OMIM]Cl, and this instigated us to compare the transfer of aqueous solutions of ionic liquids, 1 butyl-3-methyl imidazolium halides ([BMIM]I and [BMIM]Cl) into the CCl4 matrix. Not only [BMIM]I but also water molecules transferred faster compared to those in the [BMIM]Cl aqueous solution. Water molecules in CCl4 were shown to form clusters in [BMIM]I; presumably, I- anions work as nucleation centers of water clusters. PMID- 27711685 TI - Self-assembly of like-charged nanoparticles into Voronoi diagrams. AB - The self-assembly of nanoscopic building blocks into higher order macroscopic patterns is one possible approach for the bottom-up fabrication of complex functional systems. Macroscopic pattern formation, in general, is determined by the reaction and diffusion of ions and molecules. In some cases macroscopic patterns emerge from diffusion and interactions existing between nanoscopic or microscopic building blocks. In systems where the distribution of the interaction determining species is influenced by the presence of a diffusion barrier, the evolving macroscopic patterns will be determined by the spatiotemporal evolution of the building blocks. Here we show that a macroscopic pattern can be generated by the spatiotemporally controlled aggregation of like-charged carboxyl terminated gold nanoparticles in a hydrogel, where clustering is induced by the screening effect of the sodium ions that diffuse in a hydrogel. Diffusion fronts of the sodium ions and the induced nanoparticle aggregation generate Voronoi diagrams, where the Voronoi cells consist of aggregated nanoparticles and their edges are aggregation-free and nanoparticle-free zones. We also developed a simple aggregation-diffusion model to adequately describe the evolution of the experimentally observed Voronoi patterns.

AB - Monoclinic VO2 (M) is a key material for energy-efficient smart window applications. Fine crystalline VO2 particles with an ambient phase transition temperature are urgently required to achieve excellent properties including high luminous transmittance and solar heat shielding ability. Moreover, the anti oxidation ability is regarded as a significant factor which determines the lifetime of VO2-based products. In this paper, well-crystallized W-doped VO2 with low phase transition temperature, excellent solar heat shielding ability and considerable anti-oxidation ability was synthesized by a solid-state reaction process. The phase transition temperature was reduced from 67.3 degrees C to 10.8 degrees C at 2.0% W doping with an efficiency of -28.1 degrees C per at%. Importantly, an excellent balance between the phase transition temperature and the latent heat was obtained at high doping levels (1.5-2.0%). Furthermore, W doped VO2 particles exhibited a significantly longer exposure time (more than 5 h) at 300 degrees C in air than the previously reported 2 h in the literature, and the corresponding derived composite foils showed excellent luminous transmittance and solar heat shielding properties (Tlum = 49.9% and Tsol = 44.8% for 2.0% W doping). PMID- 27711688 TI - The influences of operating conditions and design configurations on the performance of symmetric electrochemical capacitors. AB - The influence of different charging current densities, charging times and several structural designs on symmetric electrochemical capacitor (EC) performance, including capacitance, energy density and power density, has been investigated via modelling and simulation. Understanding the effects of different operating conditions and structural design variables on a capacitor's performance will guide in the optimal design and fabrication of high performance ECs. The operating conditions and design configurations examined were charging current density, charging times, electrode and electrolyte effective conductivity, electrode thickness and electrode porosity. The results reveal that ECs with low electrode and electrolyte effective conductivities can only be effectively charged at low current density for long times. ECs with a high concentration of impurity ions or redox species exhibit high self-discharge rates, and fast charging of the ECs greatly reduces the self-discharge rate, compared to slow charging, provided that the effective conductivities of the electrode and electrolyte are high enough. The simulation showed the typical electrode length scale over which the liquid potential drop occurs and electrode utilization can be employed as a design parameter to optimize electrode thickness (effective thickness) for ECs designed to operate under a specific current density range. The expression for electrode utilization (u) and the guidelines that can also be used to determine optimum electrode thickness/effective thickness (100% electrode utilization), optimum charging time and optimum current density in a cell of a given voltage and effective conductivity of electrode and electrolyte, were derived. The energy and power density of ECs were increased when the electrode thickness was reduced in the given charging conditions. The Ragone plots can be used to select optimum electrode dimensions to attain given energy and power density specifications.

AB - Using inexpensive and environmentally friendly Mn oxide, a very simple method to synthesize an efficient and stable water-oxidizing electrode on the surface of a fluorine doped tin oxide electrode was reported. The electrode at pH = 13 yields a current density of 1 mA cm-2 at an overpotential of 450 mV, which is promising to be used as an anode in water-splitting systems. In higher overpotential (800 mV), a current density of 7 mA cm-2 was observed. Proposed different states of the growth of layered Mn oxide on the surface of FTO based on SEM images were also discussed. PMID- 27711690 TI - Near infrared light-mediated photoactivation of cytotoxic Re(i) complexes by using lanthanide-doped upconversion nanoparticles. AB - Platinum-based chemotherapy, although it has been well proven to be effective in the battle against cancer, suffers from limited specificity, severe side effects and drug resistance. The development of new alternatives with potent anticancer effects and improved specificity is therefore urgently needed. Recently, there are some new chemotherapy reagents based on photoactive Re(i) complexes which have been reported as promising alternatives to improve specificity mainly attributed to the spatial and temporal activation process by light irradiation. However, most of them respond to short-wavelength light (e.g. UV, blue or green light), which may cause unwanted photo damage to cells. Herein, we demonstrate a system for near-infrared (NIR) light controlled activation of Re(i) complex cytotoxicity by integration of photoactivatable Re(i) complexes and lanthanide doped upconversion nanoparticles (UCNPs). Upon NIR irradiation at 980 nm, the Re(i) complex can be locally activated by upconverted UV light emitted from UCNPs and subsequently leads to enhanced cell lethality. Cytotoxicity studies showed effective inactivation of both drug susceptible human ovarian carcinoma A2780 cells and cisplatin resistant subline A2780cis cells by our UCNP based system with NIR irradiation, and there was minimum light toxicity observed in the whole process, suggesting that such a system could provide a promising strategy to control localized activation of Re(i) complexes and therefore minimize potential side effects. PMID- 27711691 TI - HONH3Cl optimized CH3NH3PbI3 films for improving performance of planar heterojunction perovskite solar cells via a one-step route. AB - Planar heterojunction perovskite solar cells (PHJ-PSCs) constructed with one-step precursor solution spin-coating deposition (OPSSD) usually give an extremely low performance mainly due to the poor morphology and low crystallinity of the perovskite films. In this work, by incorporating a suitable HONH3Cl additive in the perovskite precursor solution, a high quality perovskite film with improved morphology and crystallinity was obtained. The UV-vis measurement of the CH3NH3I solutions without and with HONH3Cl demonstrates that the improved quality of the perovskite film can be easily attributed to a combined effect of N2, I2, H2O and CH3NH3Cl originating from the oxidation of CH3NH3I triggered by the HONH3Cl additive, which can manipulate the crystallization process of the perovskite. Accordingly, the improved performance for the HONH3Cl-induced PHJ-PSCs can also be demonstrated. At the optimized molar ratio of 1 : 1 : 0.1 for PbI2 : CH3NH3I : HONH3Cl, the PHJ-PSCs exhibit an average power conversion efficiency (PCE) of 10.61 +/- 0.51%, which is much higher than that of pristine 1 : 1 : 0 based cells without additive (7.21 +/- 0.61%), and the best performing HONH3Cl-induced device can yield a PCE as high as 11.12% with a Jsc of 18.42 mA cm-2, Voc of 0.95 V and FF of 0.63. Introducing suitable HONH3Cl as an additive into the perovskite precursor solution is really an effective route to enhance the performance of the PHJ-PSCs via OPSSD.

AB - Graphene based nanocomposites have been investigated intensively, as electrode materials for energy storage applications. In the current work, a graphene-CNT MnO2-PANI (GCM@PANI) nanocomposite has been synthesized on 3D graphene grown on nickel foam, as a highly efficient binder free electrode material for supercapacitors. Interestingly, the specific capacitance of the synthesized electrode increases up to the first 1500 charge-discharge cycles, and is thus referred to as an electrode activation process. The activated GCM@PANI nanocomposite electrode exhibits an extraordinary galvanostatic specific capacitance of 3037 F g-1 at a current density of 8 A g-1. The synthesized nanocomposite exhibits an excellent cyclic stability with a capacitance retention of 83% over 12 000 charge-discharge cycles, and a high rate capability by retaining a specific capacitance of 84.6% at a current density of 20 A g-1. The structural and electrochemical analysis of the synthesized nanocomposite suggests that the astonishing electrochemical performance might be attributed to the growth of a novel PANI nanoparticle layer and the synergistic effect of CNT/MnO2 nanostructures. PMID- 27711693 TI - Room temperature magnetoelectric coupling in intrinsic multiferroic Aurivillius phase textured ceramics. AB - Spark plasma sintering was employed in order to obtain textured Aurivillius phase ceramics that simultaneously exhibit ferroelectric and ferromagnetic properties at room temperature. The sintered multiferroics are layer-structured, nearly single-phase materials. Although a small amount of the secondary phase consisting of magnetic Co and Fe was detected by SEM/EDX, a majority of the observed ferromagnetic behaviour was attributed to the Aurivillius phase Bi4.25La0.75Ti3Fe0.5Co0.5O15 based on the observed magnetic anisotropy. The ferroelectric switching was demonstrated to exist in the Aurivillius phase ceramics by measuring the current peaks upon electric field reversal. Piezoresponse force microscopy at room temperature revelaed substantial changes of the ferroelectric domain structure when the Aurivillius phase material is subjected to an external magnetic field. PMID- 27711694 TI - Control of calcium accessibility over hydroxyapatite by post-precipitation steps: influence on the catalytic reactivity toward alcohols. AB - Hydroxyapatites are increasingly used as heterogeneous catalysts since they present atypical behaviours for many acid base reactions. The aim of this study was to discuss the possible involvement of Ca2+ Lewis and/or PO-H Bronsted acid sites belonging to the hydroxyapatite system in the conversion of 2-methylbut-3 yn-1-ol, a model molecule that is known to account for the acid base properties, and of ethanol into n-butanol. A series of hydroxyapatite samples with similar bulk properties was prepared from a lone precipitation batch, but by varying the conditions of the washing and drying steps. Although the surface depth probed by XPS exhibited similar average composition, ISS analysis revealed a gradient of calcium concentration in the first surface layers. In fact, the different conditions of drying and washing resulted in a modulation of the relative amount of Ca2+ and PO-H accessible on the top surface, as revealed by the adsorption of the CO molecule monitored by FTIR. The conversion in the two alcohol molecules is linearly dependent on the nature of the acid base pairs involved: when accessible on the top surfaces, due to their stronger acidity, the Ca2+ Lewis acid sites are preferentially involved, but they are less efficient than PO-H, as illustrated by the linear decrease of the conversion levels with the increasing relative amount of accessible Ca2+ cations. It is thus concluded that PO-H sites enhance the performances of the catalysts for the two reactions, and that washing and drying conditions allowing us to decrease the calcium accessibility at the benefit of PO H should be favoured. PMID- 27711695 TI - Ultrafast relaxation dynamics of electronically excited piperidine: ionization signatures of Rydberg/valence evolution. AB - We have investigated the electronic relaxation dynamics of gas-phase piperidine (a secondary aliphatic amine) using time-resolved photoelectron imaging. Following 200 nm excitation, spectrally sharp and highly anisotropic photoelectron data reveal ultrafast (60 fs) internal conversion between the initially excited 3px Rydberg state and the lower-lying 3s Rydberg state, mediated by the evolution of nsigma* valence character along the 3px N-C bond. This behaviour is in good agreement with previously reported findings for several tertiary aliphatic amines. In contrast to the these systems, however, much broader photoelectron signals exhibiting only very small angular anisotropy and two distinct decay timescales (180 fs and 1.7 ps) were also observed. As confirmed by our supporting calculations, this is attributable to nsigma* valence character now evolving along the N-H stretching coordinate within the 3s Rydberg state as the molecule starts dissociating to yield H atom photoproducts in conjunction with ground state piperidinyl radicals. By analogy with systems such as ammonia and morpholine, we conclude this event may occur either promptly or, alternatively, via a "frustrated" process where the system repeatedly traverses the upper cone of a conical intersection with the ground state until the required region of phase space is sampled to facilitate non-adiabatic population transfer. Our findings reveal the role of several different nuclear coordinate motions in driving stepwise internal conversion across multiple potential energy surfaces and the distinct photoionization signatures that are associated with these processes. PMID- 27711696 TI - Attachment of composite porous supra-particles to air-water and oil-water interfaces: theory and experiment. AB - We developed and tested a theoretical model for the attachment of fluid-infused porous supra-particles to a fluid-liquid interface. We considered the wetting behaviour of agglomerated clusters of particles, typical of powdered materials dispersed in a liquid, as well as of the adsorption of liquid-infused colloidosomes at the liquid-fluid interface. The free energy of attachment of a composite spherical porous supra-particle made from much smaller aggregated spherical particles to the oil-water interface was calculated. Two cases were considered: (i) a water-filled porous supra-particle adsorbed at the oil-water interface from the water phase, and, (ii) an oil-filled porous supra-particle adsorbed at the oil-water interface from the oil-phase. We derived equations relating the three-phase contact angle of the smaller "building block" particles and the contact angle of the liquid-infused porous supra-particles. The theory predicts that the porous supra-particle contact angle attached at the liquid interface strongly depends on the type of fluid infused in the particle pores and the fluid phase from which it approaches the liquid interface. We tested the theory by using millimetre-sized porous supra-particles fabricated by evaporation of droplets of polystyrene latex suspension on a pre-heated super-hydrophobic surface, followed by thermal annealing at the glass transition temperature. Such porous particles were initially infused with water or oil and approached to the oil-water interface from the infusing phase. The experiment showed that when attaching at the hexadecane-water interface, the porous supra-particles behaved as hydrophilic when they were pre-filled with water and hydrophobic when they were pre-filled with hexadecane. The results agree with the theoretically predicted contact angles for the porous composite supra-particles based on the values of the contact angles of their building block latex particles measured with the Gel Trapping Technique. The experimental data for the attachment of porous supra particles to the air-water interface from both air and water also agree with the theoretical model. This study gives important insights about how porous particles and particle aggregates attach to the oil-water interface in Pickering emulsions and the air-water surface in particle-stabilised aqueous foams relevant in ore flotation and a range of cosmetic, pharmaceutical, food, home and personal care formulations.

PMID- 27711699 TI - Facile synthesis of hierarchical Mn3O4 superstructures and efficient catalytic performance. AB - The development of novel materials with excellent performance depends not only on the constituents but also on their remarkable micro/nanostructures. In this work, manganese oxide (Mn3O4) hausmannite structures with a uniform three-dimensional (3D) flower-like hierarchical architecture have been successfully synthesized by a novel chemical route using surfactants as structure-directing agents. Microstructure analysis indicates that the obtained 3D flower-like Mn3O4 superstructure consists of a large number of two-dimensional (2D) Mn3O4 nanosheets, which is different from the reported 3D Mn3O4 hierarchical structures based on zero-dimensional nanoparticles or one-dimensional nanowires and nanorods. This 3D Mn3O4 hierarchical architecture provides us with another type of manganese oxide with different superstructural characteristics, which may have potential practical applications in the catalytic degradation of organic pollutants. The catalytic performance of this hierarchical Mn3O4 superstructure, which was prepared by three different types of structure-directing agents, including cetyltrimethylammonium bromide (CTAB), poly(vinylpyrrolidone) (PVP), and poly(ethylene oxide)-poly(propylene oxide) (P123), was evaluated for the catalytic degradation of organic pollutants, e.g. methylene blue. Interestingly, the hierarchical Mn3O4 superstructure prepared using CTAB as a template showed efficient catalytic degradation. The formation processes and possible growth mechanism of this novel 3D Mn3O4 hierarchical superstructure assembled by 2D Mn3O4 nanosheets are discussed in detail. PMID- 27711700 TI - Insight into the mechanism about the initiation, growth and termination of the C C chain in syngas conversion on the Co(0001) surface: a theoretical study. AB - The initiation, growth and termination mechanism of the C-C chain from syngas on the Co(0001) surface have been investigated using DFT calculations. Our results show that CHx (x = 1-3) formation is easier than CH3OH, both CH and CH2 species are the dominant forms of CHx (x = 1-3), both CH and CH2 species dominantly interact with CHO to form CHCHO and CH2CHO, and realizes the initial C-C chain formation. Then, CHCHO and CH2CHO prefer to be successively hydrogenated to CH3CHO, followed by C-O bond cleavage to give CH3CH; subsequently, CHO insertion into CH3CH can realize the further chain growth to form CH3CHCHO, followed by dissociation and hydrogenation to give CH3CHCH and CH3CH2CHO, respectively; further, CH3CHCH hydrogenation or CH3CH2CHO dissociation via the C-O bond cleavage can form the CH3CH-like species CH3CH2CH intermediate. Thus, the mechanism of a C-C chain growth cycle has been proposed that starts from a CH3CH2CH intermediate, followed by repeating the above C-C chain growth cycle via CH3CH intermediates, and the C-C chain growth to higher C2+ hydrocarbons and oxygenates can be realized, in which RCH2CH prefers to interact with CHO to form RCH2CHCHO, followed by its C-O bond cleavage and its hydrogenation to form R'CHCH (R' = RCH2) and R'CH2CHO (R' = RCH2), respectively, where R'CHCH hydrogenation and C-O bond cleavage of R'CH2CHO will produce R'CH2CH. Moreover, aldehyde intermediates R'CH2CHO are expected to undergo C-O bond cleavage to five R'CH2CH (R' = RCH2) rather than its desorption and its hydrogenation to alcohol. The C-C chain termination occurs at three possible positions along the growth cycle: R'CH2CHO desorption, R'CHCH with successive hydrogenation steps to alkanes or alkenes, and R'CH2CH hydrogenation to alkanes, in which the relative importance of termination of R'CHCH and R'CH2CH with hydrocarbons will depend strongly on the hydrogen coverage on the metal surface. The results of this work not only illustrate the initiation, growth and termination mechanism of the C-C chain involved in FTS on the Co(0001) surface, but also serve as a basis for the rational design of other Co surfaces toward desirable higher hydrocarbons or oxygenates.

The combined use of impact electrochemistry on screen-printed electrodes (SPEs) for the successful detection of silver nanoparticles provides an avenue for future on-site, point-of-care detection devices to be made for environmental, medicinal and biological uses.

PMID- 27711703 TI - Quantum molecular motion in the mixed ion-radical complex, [(H2O)(H2S)]. AB - The cation dimer of water and hydrogen sulfide, [(H2O)(H2S)]+, serves as a fundamental model for the oxidation chemistry of H2S. The known oxidative metabolism of H2S by biological species in sulfur-rich environments has motivated the study of the inherent properties of this benchmark complex, with possible mechanistic implications for modern water oxidation chemistry. The low-energy isomer of this open-shell ion is a proton-transferred (PT) structure, H3O+SH. An alternative PT structure, H3S+OH, and a hemibonded (HB) isomer, [H2O.SH2]+, are also stable isomers, placing this complex intermediate to known (H2O)2+ (PT) and (H2S)2+ (HB) limiting regimes. This intermediate character suggested the possibility of unique molecular motion, even in the vibrational ground state. Path integral molecular dynamics and anharmonic vibrational spectroscopy simulations have been performed in this study, in order to understand the inherent quantum molecular motion of this complex. The resulting structural distributions were found to deviate significantly from both classical and harmonic analyses, including the observation of large-amplitude anharmonic motion of the central proton and nearly free rotation of the terminal hydrogens. The predicted vibrational spectra are particularly unique and suggest characteristic signatures of the strong electronic interactions and anharmonic vibrational mode couplings in this radical cation.

The in vitro transfection experiment demonstrates that the complexes can be used to deliver pCMV-tdTomato-N1 plasmid which expresses red fluorescent protein. The confocal studies show that the fluorescent nature of complexes is advantageous for visualizing the intracellular delivery of metal complexes as well as transfection efficiency using two distinct emission windows.

AB - Molecular spintronics is an effervescent field of research, which aims at combining spin physics and molecular nano-objects. In this article, we show that phthalocyanine molecules integrated in magnetic tunnel junctions (MTJs) can lead to magnetoresistance effects of different origins. We have investigated cobalt and manganese phthalocyanine molecule based magnetic tunnel junctions. CoPc MTJs exhibit both tunneling magnetoresistance (TMR) and tunneling anisotropic magnetoresistance (TAMR) effects of similar magnitude. However, for MnPc MTJs, a giant TAMR dominates with ratios up to ten thousands of percent. Strong features visible in the conductance suggest that spin-flip inelastic electron tunneling processes occur through the Mn atomic chain formed by the MnPc stacks. These results show that metallo-organic molecules could be used as a template to connect magnetic atomic chains or even a single magnetic atom in a solid-state device.

AB - A series of silver tris(perfluoroethyl)trifluorophosphate (Ag[FAP]) complexes with various ligands (acetonitrile ACN, chloroacetonitrile Cl-ACN, acrylonitrile acryl-CN, pyridine py, ethylenediamine en and propene C3H6) have been synthesized starting from Ag[NO3] and K[FAP] using three different routes. Physicochemical properties as well as crystal structures ([Ag(ACN)2/4][FAP], [Ag(py)2][FAP]) were determined and the suitability of such Ag salts for propene/propane separation processes was investigated. The investigated silver complexes exhibit either low melting points or form liquid complexes when contacted with gaseous propene at 30 degrees C. This makes them promising separation materials for both liquid membranes and absorber fluids due to their high silver content and significant propene capacity. Single (iGSC) and mixed (NMR) gas solubilities as well as diffusion coefficients (PFG-NMR) of propene and propane were determined to predict the theoretical selectivity of solubility, membrane selectivity, capacity and transport properties of the silver salts according to the solution diffusion model. A strong influence of the number and type of ligands on chemical complexation, physicochemical properties and separation performance has been observed.

AB - In conjunction with ab initio potential energy and dipole moment surfaces for the electronic ground state, we have made a theoretical study of the radiative lifetimes for the hydronium ion H3O+ and its deuterated isotopologues. We compute the ro-vibrational energy levels and their associated wavefunctions together with Einstein coefficients for electric dipole transitions. A detailed analysis of the stability of the ro-vibrational states has been carried out and the longest living states of the hydronium ions have been identified. We report estimated radiative lifetimes and cooling functions for temperatures <200 K. A number of long-living meta-stable states are identified, capable of population trapping. PMID- 27711707 TI - Prediction of proton affinities of organic molecules using the any-particle molecular-orbital second-order proton propagator approach. AB - We assess the performance of the recently developed any-particle molecular orbital second-order proton propagator (APMO/PP2) scheme [M. Diaz-Tinoco, J. Romero, J. V. Ortiz, A. Reyes and R. Flores-Moreno, J. Chem. Phys., 2013, 138, 194108] on the calculation of gas phase proton affinities (PAs) of a set of 150 organic molecules comprising several functional groups: amines, alcohols, aldehydes, amides, ketones, esters, ethers, carboxylic acids and carboxylate anions. APMO/PP2 PAs display an overall mean absolute error of 0.68 kcal mol-1 with respect to experimental data. These results suggest that the APMO/PP2 method is an alternative approach for the quantitative prediction of gas phase proton affinities. One novel feature of the method is that a PA can be obtained from a single calculation of the optimized protonated molecule. PMID- 27711708 TI - Coordination versatility of p-hydroquinone-functionalized dibenzobarrelene-based PC(sp3)P pincer ligands. AB - The manuscript describes the synthesis and coordination chemistry of a novel diphosphine pincer ligand based on a p-hydroquinone-functionalized dibenzobarrelene scaffold. The p-hydroquinone fragment of the ligand is oxidatively and coordinatively non-innocent and may render new reactivity to the metal center due to implied reversible redox behavior, tautomeric interconversion and metal-hydroxyl/alkoxide coordination switch of the pendant hydroxyl side-arm. Palladium, platinum and iridium complexes were prepared and characterized. Investigation of their coordination chemistry revealed that while tautomeric equilibrium exists in free ligands and in the chelate non-metalated complexes, it is essentially blocked in the corresponding C(sp3)-pincer compounds due to stabilizing hemilabile coordination of the hydroxyl group. However, its presence in close proximity to the metal center is essential for catalyzing acceptorless dehydrogenation of alcohols by the iridium complexes via the outer-sphere hydrogen transfer mechanism. Remarkably, we found a similar activity for the analogous palladium complexes, which is not characteristic of this metal. This unprecedented reactivity of palladium stresses the fact that besides the choice of an active metal, transformation-oriented design of the ligand is crucial for catalysis. PMID- 27711709 TI - A scalable architecture for quantum computation with molecular nanomagnets. AB - A proposal for a magnetic quantum processor that consists of individual molecular spins coupled to superconducting coplanar resonators and transmission lines is carefully examined. We derive a simple magnetic quantum electrodynamics Hamiltonian to describe the underlying physics. It is shown that these hybrid devices can perform arbitrary operations on each spin qubit and induce tunable interactions between any pair of them. The combination of these two operations ensures that the processor can perform universal quantum computations. The feasibility of this proposal is critically discussed using the results of realistic calculations, based on parameters of existing devices and molecular qubits. These results show that the proposal is feasible, provided that molecules with sufficiently long coherence times can be developed and accurately integrated into specific areas of the device. This architecture has an enormous potential for scaling up quantum computation thanks to the microscopic nature of the individual constituents, the molecules, and the possibility of using their internal spin degrees of freedom.

AB - This article demonstrates comprehensive studies on different visible-light driven photoelectrochemical and photocatalytic aspects of a hydrothermally synthesized n type H2Ti3O7 (HTO) nanowire mesh and its carbon and nitrogen functionalized counterparts, namely C-HTO and N-HTO. It was found that the presence of various defect states within the band gap of HTO, C-HTO and N-HTO nanowires, make them photoactive under visible-light. The photo-conversion efficiencies of HTO, C-HTO, and N-HTO nanowire electrodes are about 0.066, 0.129, and 0.076%, respectively, at around 1 V vs. Ag/AgCl. Carbon functionalization of HTO nanowires has been found to be most beneficial in increasing the charge carrier density, resulting in the highest current density, high photo conversion efficiency, remarkable photoelectrochemical water splitting performance and enhanced photocatalytic activity. The photocurrent density of the C-HTO NWs was found to be 0.0562 mA cm 2 at 1 V vs. Ag/AgCl, which is almost two times that of the pristine HTO NWs (0.029 mA cm-2). Although nitrogen functionalization increases the charge carrier density of the HTO nanowires, nitrogen incorporation produces lots of recombination centres in the nanowires, which are found to play a detrimental role in the photoelectrochemical and photocatalytic performance of N-HTO nanowires, limiting the expected performance. Therefore, the present study demonstrates a suitable surface engineering technique for nanostructures to maximize the utilization of green solar light.

The design features a 2,2-bis(aminomethyl)propionic acid core to connect and pre organize binding groups. The cation binding is provided by a sodium selective N acyl aza-18-crown-6 subunit whereas for anion complexation, two urea groups (receptor 2) or two squaramide groups (receptor 3) were introduced. Beyond acting as anion binding sites, the urea and squaramide groups were used to support sodium cation complexation through metal carbonyl oxygen lone pair interactions. The receptors were found to bind sodium salts of chloride, bromide and nitrate much more strongly than the corresponding ions accompanied by counterions that do not coordinate to the receptor. For example, chloride binding to receptor 2 enhances the strength of sodium complexation by up to 23 times. Conversely, sodium binding enhances chloride recognition by a factor of three. Receptor 3 containing squaramide units, binds sodium chloride and bromide with a similar albeit lower cooperativity. Moreover, unprecedentedly tight binding of these salts was achieved, with association constants as high as log Ka = 6.52 M-1 for NaCl salt complexation.

AB - A nanofluid (NF) is composed of a base liquid and suspended nanoparticles (NPs). High-performance NFs exhibit significantly better heat conductivities, as compared to their base liquids. In the present work, we applied all-atom molecular dynamics (MD) simulations to characterize diffusive and ballistic energy transfer mechanisms within nanodiamonds (NDs), carbon nanotubes (CNTs), and N-butylpyridinium tetrafluoroborate ionic liquid (IL). We showed that heat transfer within both NDs and CNTs is orders of magnitude faster than that in the surrounding IL, whereas diffusion of all particles in the considered NF is similar. Intramolecular heat transfer in NPs is a key factor determining the difference of NFs from base liquids. Solvation free energy of NDs and CNTs in ILs was estimated from MD simulations. The geometric dimensions of NPs were shown to be a major source of entropic penalty. Temperature adjusts the entropic factor substantially by modifying a genuine local structure of the bulk base liquid. Our work contributes to engineering more stable and productive suspensions of NPs in ILs, which are necessary for essential progress in the field of NFs.

AB - A new trimeric cluster [(SiW9Nb3O38)3MnO3(H2O)3]13- (1) with three Keggin-type trilacunary SiW9 units connected by a {MnNb9} core were structurally characterized. The polyanion 1 features three corner-shared {Nb3O3} fragments that are linked to each other on two sides via three Nb-O-Nb bridges and by a {MnII} linker. To the best of our knowledge, polyanion 1 represents the first example of a trimeric niobotungstate cluster reported to date, and is revealed for the first time uniting a family of polytungstosilicate clusters. The formation of polyanion 1 exemplifies the reactivity of {(NbO2)3SiW9} with a manganese metal ion, defining a new in situ synthetic strategy for {(NbO2)3SiW9} based derivatives, featuring POM chemistry between Nb/W mixed-addendum POMs and various transition-metal or lanthanide species. PMID- 27711714 TI - Reaction mechanisms of carbon dioxide, ethylene oxide and amines catalyzed by ionic liquids BmimBr and BmimOAc: a DFT study. AB - The mechanisms of the one-pot conversion of carbon dioxide, ethylene oxide, and aniline to 3-phenyl-2-oxazolidionone catalyzed by the binary ionic liquids of BmimBr and BmimOAc were explored using the DFT methods. The complex reaction above comprises of two parallel reactions and a subsequent cascade reaction. DFT calculations on reaction pathways and energy profiles reveal that the electrostatic and hydrogen-bond effects of BmimBr play a crucial role in the parallel reactions for the generation of ethylene carbonate and 2-phenylamino ethanol. Further, the subsequent cascade reaction to generate 3-phenyl-2 oxazolidinone catalyzed by BmimOAc follows a stepwise mechanism, which is more favorable than the concerted mechanism governed by BmimBr. In addition, BmimBr can accelerate the side reaction of aniline and ethylene oxide to yield a mixture of oligomers, which accords with the experimental observation. This theoretical work provides a deep insight into the catalytic roles of binary ionic liquids and also inspires us to design high efficient catalysts for the conversion of carbon dioxide further. PMID- 27711715 TI - Maximizing ion current rectification in a bipolar conical nanopore fluidic diode using optimum junction location. AB - The ion current rectification has been obtained as a function of the location of a heterojunction in a bipolar conical nanopore fluidic diode for different parameters to determine the junction location for maximum ion current rectification using numerical simulations. Forward current peaks for a specific location of the junction and reverse current decreases with the junction location due to a change in ion enrichment/depletion in the pore. The optimum location of the heterojunction shifts towards the tip with base/tip diameter and surface charge density, and towards the base with the electrolyte concentration. The optimum location of the heterojunction has been approximated by an equation as a function of pore length, base/tip diameter, surface charge density and electrolyte concentration. The study is useful to design a rectifier with maximum ion current rectification for practical purposes.

AB - An efficient oxygen-phosphoryl bond-forming reaction via iron-catalyzed cross dehydrogenative coupling has been developed. This transformation proceeds efficiently under oxidant- and halide-free reaction conditions with H2 liberation, and represents a straightforward method to prepare valuable organophosphoryl compounds from the readily available alcohols and P(O)-H compounds. PMID- 27711717 TI - Transition metal complexes of the pyridylphosphine ligand o-C6H4(CH2PPy2)2. AB - The synthesis and coordination behaviour of the pyridylphosphine ligand o C6H4(CH2PPy2)2 (Py = 2-pyridyl) are reported. The phosphine selenide was synthesised and the 1JPSe value of 738 Hz indicates the phosphorus atoms have a similar basicity to PPh3. The ligand reacts with platinum(ii) and palladium(ii) complexes to give simple diphosphine complexes of the type [MX2(PP)] (M = Pt, X = Cl, I, Me, Et; M = Pd, X = Cl, Me). When the ligand is reacted with chloromethyl(hexa-1,5-diene)platinum the [PtClMe(PP)] complex results, from which a series of unsymmetrical platinum complexes of the type [PtMeL(PP)]+ (L = PPh3, PTA, SEt2 and pyridine) can be made. This enabled the comparison of the cis and trans influences of a range of ligands. The following cis influence series was compiled based on 31P NMR data of these complexes: Py ~ Cl > SEt2 > PTA > PPh3. Reaction of [PtClMe(PP)] with NaCH(SO2CF3)2 and carbon monoxide slowly formed an acyl complex, where the CO had inserted in the Pt-Me bond. Attempts to achieve P,P,N chelation, through abstracting the chloride ligand in [PtClMe(PP)], were unsuccessful. When the ligand reacted with platinum(0), palladium(0) and silver(i) complexes the bis-chelated complexes [M(PP)2] (M = Pt, Pd) and [Ag(PP)2]+ were formed respectively. Reaction of the ligand with [Ir(COD)(MU Cl)]2 formed [IrCl(PP)(COD)]. When the chloride ligand was abstracted, the pyridyl nitrogens were able to interact with the iridium centre facilitating the isomerisation of the 1,2,5,6-eta4-COD ligand to a 1-kappa-4,5,6-eta3-C8H12 ligand. The X-ray crystal structure of [Ir(1-kappa-4,5,6-eta3-C8H12)(PPN)]BPh4 confirmed the P,P,N chelation mode of the ligand. In solution, this complex displayed hemilabile behaviour, with the pyridyl nitrogens exchanging at a rate faster than the NMR time scale at room temperature. PMID- 27711718 TI - Water bridges anchored by a C-HO hydrogen bond: the role of weak interactions in molecular solvation. AB - The imidazole group, characterized by an activated C(2)-H bond sandwiched between two N atoms, occurs in several biomolecules including alkaloids, amino acids, and nucleobases. The speculated role of this potential hydrogen bond donor in shaping the solvation shell around the neutral imidazole moiety, however, remains unidentified. In contrast, hydrogen bonding and electrostatic interactions are commonly observed in the imidazolium cation where the acidity of the C(2)-H bond is markedly enhanced. Here, we show direct evidence of the weakly activated C(2) H bond in shaping the solvation shell of neutral imidazole, via spectroscopic characterization of the water clusters (Wn, n = 2-4) of two model compounds, benzimidazole (BIM) and N-methylbenzimidazole (MBIM). Infrared spectra in the OH, NH, and CH stretching regions allow unambiguous detection of a N-WW-C(2)H binding motif in the doubly hydrated cluster of both molecules. Remarkably, H-bonded water bridges between the N atom and N-H bond in BIM-W3,4 clusters are switched to the C(2)-H bond in MBIM-W3,4 with comparable binding strength, indicating that the weakly activated C(2)-H bond in the neutral imidazole moiety can serve as a potent H-bond donor.

AB - The effect of the alkyl chain length and alkoxy groups on the viscosity and related properties of polysilsesquioxanes (PSQs) prepared by cosolvent-free hydrolytic polycondensation from n-alkyltrialkoxysilane-water binary systems via aging was investigated. n-Alkyltrialkoxysilanes with ethyl, n-propyl, and n-butyl groups gave PSQ liquids, whereas those with methyl groups yielded gels. The viscosity of the PSQ liquids remained stable over a month at room temperature despite the presence of many SiOH groups, and decreased with an increase in the alkyl chain length. The aging step was crucial for obtaining PSQ liquids with low viscosities, and both n-alkyltrimethoxysilane and n-alkyltriethoxysilane with the same alkyl group produced PSQ liquids with comparable viscosities. However, during aging, liquid-liquid phase separation occurred only in the solutions derived from alkyltrimethoxysilanes. These observations confirmed that liquid liquid phase separation is not essential for the preparation of PSQ liquids. The temperature dependence of the viscosity indicated that the PSQ liquids are fragile. PMID- 27711720 TI - Fabrication of RGD-conjugated Gd(OH)3:Eu nanorods with enhancement of magnetic resonance, luminescence imaging and in vivo tumor targeting. AB - The development of multimodal probes with magnetic resonance imaging (MRI) and intraoperative fluorescence imaging is the most challenging task in the field of tumor diagnosis. Herein, a simple one-pot hydrothermal method is used to prepare Eu-doped Gd(OH)3 nanorods (Gd(OH)3:Eu NRs) with good fluorescence and the longitudinal relaxivity r1 value of 4.78 (Gd mM s-1). After dual-functionalized maleimide-polyethylene glycol-succinimide (Mal-PEG-NHS) macromolecules are coated on the surface of Gd(OH)3:Eu NRs (PEG-NRs), the results of a lower degradation ratio in newborn calf serum (NCS), reactive oxygen species (ROS) generation in L929 cells and the hemolytic rate of PEG-NRs show their good cyto-compatibility and longer blood circulation time. Moreover, the actively tumor-targeting properties are endowed to NRs through the conjugation of cyclic arginine-glycine aspartic acid (cRGD) (denoted RGD-NRs). The bio-distributions of RGD-NRs in tumor bearing nude mice via tail-vein injection indicate that RGD-NRs are specifically taken-up by gliomas. The tests of in vivo T1-weighted MR imaging via tail-vein injection confirm that RGD-NRs possess a higher positive signal-enhancement ability in gliomas. Besides, the better luminescence imaging of living cells under a fluorescence microscope and the clear in vivo fluorescence imaging further confirm the targeting properties and better in vivo optical imaging behavior of RGD-NRs. PMID- 27711721 TI - Unraveling the sub-nanoscopic structure at interphase in a poly(vinyl alcohol) MOF nanocomposite, and its role in thermo-mechanical properties. AB - A microscopic model of the interfacial region is required to improve understanding of the role of local structure in bulk physical properties in metal organic framework-based polymer nanocomposites. A zeolitic imidazolate framework (ZIF-8)-based (loading 2-30 wt%) composite of poly vinyl alcohol (PVA) is studied as a model system to investigate the role of interfacial interaction in molecular packing, glass transition process and tensile properties. Attractive interfacial interaction between the surface of ZIF particles and PVA chains is established by Fourier transform infra red (FTIR) measurements. The morphology of the nanocomposites is characterized using X-ray diffraction and scanning electron microscopy (SEM), showing that aggregation of particles started from 5 wt% of ZIF 8. At low loadings, occurrence of two glass transitions measured using differential scanning calorimetry indicates two spatial zones, viz. interphase and bulk layers, of different packing density in the PVA matrix. With increase in loading, molecular packing throughout the polymer matrix is changed as the interparticle distance and interphase width become comparable. At the highest loading, PVA shows bulk glass transition temperature because of the non significant volume fraction of interphase resulting from aggregation of ZIF. Molecular packing (free volume structure) of PVA in the nanocomposites is investigated using ortho-positronium lifetime distributions, which show that large vacant spaces are created at the interfacial region leading to a low density interphase. The existence of a low-density interphase is also supported by bulk-density measurements of the nanocomposites. Tensile testing measurements show a decrease in ductility of the nanocomposites, indicating enhancement in rigidity of polymer chains at the interfacial region because of attractive interfacial interaction. This study indicates that the polymer chain framework at the interfacial region in PVA-MOF nanocomposites can be represented by a rigid but rather open network. PMID- 27711722 TI - Hydrazine as a hydrogen carrier in the photocatalytic generation of H2 using CdS quantum dots. AB - The compelling need for safe storage and transportation of H2 has made liquid phase materials safer H2-carriers with a high gravimetric and volumetric hydrogen density. Unlike thermal or electrocatalytic decomposition on precious metal catalysts, a photocatalytic route to decomposing these liquid-phase materials can offer triggered onboard production of H2 and help mitigate the safety issues concerned with H2 storage. We have investigated visible-light induced H2 evolution from aqueous hydrazine using CdS quantum dots (QDs) as metal-free photocatalysts. Hydrazine acts as a H2 carrier as well as a donor, giving rise to a visible-light induced H2 evolution activity as high as 33 mmol h-1 g-1 at pH 8. This has been achieved by the use of CdS QDs capped with S2- ligands. The use of larger ligands such as mercaptopropionic acid hinders the adsorption of hydrazine onto CdS QDs and significantly decreases the activity. The effect of pH on the hydrogen yield in aqueous hydrazine has also been examined.

AB - beta-Functionalization of meso-tetrakis(3,5-di-tert-butyl-4 hydroxyphenyl)porphyrin with electron acceptors such as formyl and dicyanovinyl has been reported for the first time. 2-Formyl-5,10,15,20-tetrakis(3',5'-di-tert butyl-4'-hydroxyphenyl)porphyrinatocopper(ii) (Cu-TDtBHPP-CHO) crystallizes in the triclinic space group P1[combining macron], [a = 10.8479(4) A, b = 14.6207(5) A, c = 15.9745(5) A, V = 2198.97(13) A3] and exhibits an almost planar structure and a square planar geometry. beta-Formyl/dicyanovinyl substituted porphyrins such as Cu-TDtBHPP-CHO, Ni-TDtBHPP-CHO, Cu-TDtBHPP-MN (1), Ni-TDtBHPP-MN (2) and H2-TDtBHPP-MN (3) exhibited red-shifted optical absorption features (Deltalambdamax = 13-40 nm) in CH2Cl2 compared to the corresponding MTPPs. beta Dicyanovinyl substituted porphyrins were developed as a quantitatively operating 'lab-on-a-molecule' for the visual detection of F- and CN- ions. Having a CN- ion responsive dicyanovinyl moiety and a F- ion responsive redox-active 3,5-di-tert butyl-4-hydroxyphenyl groups, they detect F- and CN- ions simultaneously by switching unique structural changes between porphyrin, porphodimethene and porphyrinogen along with distinct colour changes which were monitored by UV-Vis NIR, fluorescence and NMR spectroscopic techniques.

AB - We report a detailed experimental and theoretical study of the gas phase reactivity of Au+ with CO, O2, N2 and their mixtures in the presence of a trace amount of water impurity. The gold cation is found to strongly interact with CO and H2O molecules via successive addition reactions until reaching saturation. The stoichiometry of the formed complex is determined by the strength of the binding energy of the neutral molecule to the gold cation. CO binds the strongest to Au+, followed by H2O, N2 and then O2. We found that the gold cation (Au+) can activate the O2 molecule within the Au+(CO)2(O2) complex which could react with another CO molecule to form Au+(CO)(CO2) + CO2. The product Au+(CO)(CO2) is observed experimentally with a small intensity at room temperature. However, the presence of water leads to the formation of Au+(CO)(H2O)(O2) instead of Au+(CO)2(O2) due to the strong interaction between Au+ and water. The current experiments and calculations might lead to a molecular level understanding of the interactions between the active sites, reactants and impurities which could pave the way for the design of efficient nanocatalysts.

AB - The syntheses of two new ligands based on a calix[4]arene scaffold in the cone conformation functionalized on the phenolic positions 1 and 3 by diethylthiophosphonates (L1) or tetra(tri)thioethyleneglycol (L2) crowns are described. Together with ligand L3, the parent calix[4]arene substituted by a penta(tetra)thioethyleneglycol crown, the spectroscopic properties of the ligands were determined by means of UV-Vis absorption spectroscopy and steady-state and time-resolved fluorescence spectroscopy, showing that the ligands display modest but non-negligible intrinsic fluorescence properties (phifluo = 0.023; 0.026 and 0.029 for L1, L2 and L3 in CH2Cl2, respectively). The X-ray crystal structures of ligand L1, and of its synthetic precursor were determined and analyzed for their capacity to accommodate the incoming cationic species. The ligands were further investigated for their complexation properties of divalent cations such as Cu2+, Zn2+, Hg2+ and Cd2+ (under their nitrate salts) in 1 : 1 CH3CN/CH2Cl2 solutions (I = 0.01 M Et4NNO3, T = 25.0(2) degrees C), in which the additions of cations were monitored by absorption and steady-state fluorescence spectrophotometries. The stoichiometries of the corresponding complexes were assessed by ESI-MS, while insights into the structures of the complexes in solution were obtained with density functional theory (DFT) calculations. The influence of the sulphur and phenol coordinating moieties was addressed to show that the thiocrown compounds L2 and L3 displayed a marked affinity towards the soft mercuric cation (Deltalog K >= 2), with no particular size selectivity effect, whereas ligand L1 can accommodate both the thio and phenol units to coordinate with Cu(ii). Altogether, these results point to the use of L3 as a selective fluoroionophore for detection of Hg2+.

AB - Bladder cancer is still a common malignancy of the urinary tract due to the high metastasis rate and unexpected side effects of drug treatments. The acidic environment of the urinary bladder also strongly limits the efficacy of the chemotherapeutic agents during the treatment of bladder cancer. In this study, a series of selenadiazole derivatives (SeDs) have been rationally designed and synthesized and could actively suppress the progression and metastasis of bladder cancer cells. SeDs demonstrated better antiproliferative activity and higher stability under different physiological conditions, especially in an acidic urocystic environment, than mitomycin, a clinically used anti-bladder cancer drug. In particular, compound 1b displayed better selectivity between cancer and normal cells in comparison with other compounds. Studies on the structure activity relationship revealed that the introduction of strong electron donating substituents, such as the methoxy group, resulted in a dramatic enhancement in the anticancer efficacy. Furthermore, 1b induced anti-migration and anti-invasion activities against bladder cancer cells. Mechanistic investigation revealed that compound 1b was able to enter the cells through endocytosis and then trigger reactive oxygen species (ROS) overproduction, further causing DNA damage-mediated p53 phosphorylation and promoting cancer cell apoptosis by regulating the AKT and MAPKs signaling pathways. Altogether, the study provides a strategy for rational design of selenadiazole derivatives with improved stability to antagonize bladder cancer.

AB - Octahedral tungsten iodide clusters equipped with apical ligands (L) are synthesized to implement substantial photophysical properties. The [W6I8(CF3COO)6]2- cluster reported herein is the first example of a family of ligand substituted [W6I8L6]2- clusters. Such compounds are expected to exhibit a rich photochemistry in which the apical ligands play a crucial role. The versatile solid state and solution phase photophysical properties of (TBA)2[W6I8(CF3COO)6] described herein parallel characteristics obtained in some photophysically active organic compounds, including a broad absorption in the UV/VIS region. Upon irradiation of this compound, a broad red emission is observed in the VIS/NIR region resulting from excited triplet states, and singlet oxygen (a1Deltag) is generated in the presence of O2.

AB - First principles calculations predict the promising thermoelectric material ZnGeSb2 with a huge power factor (S2sigma/tau) on the order of 3 * 1017 W m-1 K-2 s-1, due to the ultra-high electrical conductivity scaled by a relaxation time of around 8.5 * 1025 Omega-1 m-1 s-1, observed in its massive Dirac state. The observed electrical conductivity is higher than the well-established Dirac materials, and is almost carrier concentration independent with similar behaviour of both n and p type carriers, which may certainly attract device applications. The low range of thermal conductivity is also evident from the phonon dispersion. Our present study further reports the gradual phase change of ZnGeSb2 from a normal semiconducting state, through massive Dirac states, to a topological semi metal. The maximum power factor is observed in the massive Dirac states compared to the other two states.

AB - Isometrically dibromated thienyl-containing aza-BODIPYs CDB-1 and BDB-2 with potential use as photosensitizers (PSs) were successfully prepared and their photophysical properties were fully characterized. Singlet oxygen generation experiments were also performed. In this regard, PS CDB-1 was found to be more effective and had about two-fold rate enhancement compared to PS BDB-2.

AB - A series of heteroleptic [Cu(N^N)(P^P)][PF6] complexes is described in which P^P = bis(2-(diphenylphosphino)phenyl)ether (POP) or 4,5-bis(diphenylphosphino)-9,9 dimethylxanthene (xantphos) and N^N = 4,4'-diphenyl-6,6'-dimethyl-2,2'-bipyridine substituted in the 4-position of the phenyl groups with atom X (N^N = 1 has X = F, 2 has X = Cl, 3 has X = Br, 4 has X = I; the benchmark N^N ligand with X = H is 5). These complexes have been characterized by multinuclear NMR spectroscopy, mass spectrometry, elemental analyses and cyclic voltammetry; representative single crystal structures are also reported. The solution absorption spectra are characterized by high energy bands (arising from ligand-centred transitions) which are red-shifted on going from X = H to X = I, and a broad metal-to-ligand charge transfer band with lambdamax in the range 387-395 nm. The ten complexes are yellow emitters in solution and yellow or yellow-orange emitters in the solid state. For a given N^N ligand, the solution photoluminescence (PL) spectra show no significant change on going from [Cu(N^N)(POP)]+ to [Cu(N^N)(xantphos)]+; introducing the iodo-functionality into the N^N domain leads to a red-shift in lambda compared to the complexes with the benchmark N^N ligand 5. In the solid state, [Cu(1)(POP)][PF6] and [Cu(1)(xantphos)][PF6] (fluoro-substituent) exhibit the highest PL quantum yields (74 and 25%, respectively) with values of tau1/2 = 11.1 and 5.8 MUs, respectively. Light-emitting electrochemical cells (LECs) with [Cu(N^N)(P^P)][PF6] complexes in the emissive layer have been tested. Using a block-wave pulsed current driving mode, the best performing device employed [Cu(1)(xantphos)]+ and this showed a maximum luminance (Lummax) of 129 cd m-2 and a device lifetime (t1/2) of 54 h; however, the turn-on time (time to reach Lummax) was 4.1 h. Trends in performance data reveal that the introduction of fluoro-groups is beneficial, but that the incorporation of heavier halo substituents leads to poor devices, probably due to a detrimental effect on charge transport; LECs with the iodo-functionalized N^N ligand 4 failed to show any electroluminescence after 50 h.

AB - Tin(iv) sulfide (SnS2), as a mid-band-gap semiconductor shows good potential as an excellent photocatalyst due to its low cost, wide light spectrum response and environment-friendly nature. However, to meet the demands of large-scale water treatment, a SnS2 photocatalyst with a red-shifted band gap, increased surface area and accelerated molecule and ion diffusion is required. Doping is a facile method to manipulate the optical and chemical properties of semiconductor materials simultaneously. In this work, SnS2 photocatalysts with varied Ag doping content are synthesized through a facile one-step hydrothermal method. The product is characterized by XRD, SEM, TEM and UV-Vis spectrometry. The photocatalytic activity of the as-prepared Sn1-xAgxS2 is studied by the degradation of methylene blue (MB) dye under solar light irradiation. It is found that increasing the Ag dopant concentration can effectively increase the solar light adsorption efficiency of the photocatalyst and accelerate heterogeneous photocatalysis. The optimal concentration of Ag dopant is found to be 5% with the highest rate constant being 1.8251 hour-1. This study demonstrates that an optimal amount of Ag doping can effectively increase the photocatalytic performance of SnS2 and will promote the commercialization of such photocatalysts in the photocatalytic degradation of organic compounds.

AB - With the aim of tuning the structures by using oxime ligands with different non coordinating groups, three aromatic oxime ligands were designed by fusing oxime groups ([double bond, length as m-dash]N-OH) onto different non-coordinating groups. Their reactions with the corresponding Mn(ii) salts gave five manganese clusters [Mn(MU3-O)(L1)3(DMF)(H2O)3Cl].2DMF.CH3OH (1), [Mn(MU3 O)(L2)3(OAc)(CH3OH)2] (2), [Mn(MU3-O)2(L2)6(H2O)(py)7](ClO4)2.py.0.5CH3OH.2H2O (3), [MnO4(L2)8(DMF)4].DMF.6CH3CN (4), and [MnMnO4(L3)12].3DMF.6H2O (5), in which H2L1, H2L2 and HL3 represent indane-1,2,3-trione-1,2-dioxime, acenaphthenequinone dioxime, and 9,10-phenanthrenedione-9-oxime, respectively. Their structures were determined and studied in detail. 1 and 2 show planar triangular trinuclear Mn structures. 3 has a hexanuclear Mn skeleton formed from two Mn triangular units through inter-trinuclear mutual coordination. 4 and 5 present octanuclear skeletons constructed from planar triangular Mn3O and tetrahedral Mn4O secondary building units, respectively, with different symmetries and different oxidation states of the manganese ions. Their structural studies reveal a significant contribution of the parent rings for fusing oxime groups, different non coordinating groups and anions to the formation of different cluster skeletons. Their magnetic properties were investigated and simulated, which revealed the presence of dominant antiferromagnetic interactions between the metal ions in these compounds.

AB - We report a simple, low-cost methodology for unprecedentedly enhancing the photocatalytic activity of layered inorganic semiconductors. A layered titanate with a lepidocrocite-type structure scarcely showed photocatalytic activity for a test reaction, the oxidative decomposition of formic acid in water into CO2, under simulated solar light, but it showed highly enhanced photocatalytic activity upon mixing with a much smaller amount (approximately 10 wt%) of commercially available TiO2 nanoparticles (P25) in water. The photocatalytic activity of the mixture was approximately 5 times that of P25, a benchmark photocatalyst. From various analyses, the enhancement resulted from the transfer of photoexcited electrons from the layered titanate to P25 at their particle interfaces and retardation of charge recombination. When applied to a photocatalyst for H2 production from water containing methanol under simulated solar light, the layered titanate/P25 mixture showed considerably enhanced activity and the apparent quantum yield was 23% (at 320 nm). By replacing P25 with Pt co-catalyst-loaded P25, the apparent quantum yield of the mixture increased from 23 to 73%, although an extremely small amount (below 0.06%) of Pt was used in the system.

Herein, we have studied the coordination of three amidoxime ligands (6-methoxyl-naphtha-2 amidoxime, NAO; glutarimidedioxime, GIO; and gluardiamidoxime, GDO) with uranyl in the gas phase by mass spectrometry. The identifications of the electrospray ionization (ESI) generated species, the fragmentation pathways upon dissociation, the relative binding affinities of the ligands, and the hydration reactions have been conducted and compared to reveal their structural information in the gas phase. The binding modes for all the complexes were suggested based on the experimental results and were further studied by density functional theory (DFT) calculations.

AB - To overcome tough conditions currently used for the preparation of nanostructured hematite films on a conducting substrate, a rational and easy method of chemical etching involving Fe3+ release and material growth in the presence of OH- has been developed. By carefully tuning the parameters influencing the morphologies of hematite, including the synthetic procedure, the concentration of etching solution, temperature, etching time and the morphology controlling surfactant, hematite films grown on iron foil with various morphologies (e.g. nanorod, nanowire, ultrathin nanoflake and cauliflower-like shape) have been achieved. In particular, it is found that F- is an effective surfactant to control the morphology as well as the crystallization process of hematite. Ultrathin nanoflakes having a minimized feature size exhibit the best photocurrent of 0.5 mA cm-2 (1.23 V vs. RHE, RHE is reversible hydrogen electrode) among the samples tested as a result of facilitated hole diffusion to the electrolyte and thus lowered carrier recombination. Compared with pristine hematite, a nearly tripled photocurrent is observed when H2O2 is added in the electrolyte as a hole scavenger, suggesting the presence of a charge injection barrier in the surface of samples. According to this, the strategy of Co2+ treatment is utilized and the improved photocurrent is seen, likely due to the improved water oxidation kinetics and surface state passivation. We believe that this convenient and economical method can be extended to the synthesis of other alkaline metal oxide nanomaterials as long as the redox potential of S2O82-/SO42- is higher than Mn+/M (M refers to metal).

AB - Electronic and free energy barriers for a series of gas-phase RDX decomposition mechanisms have been obtain using coupled cluster singles, doubles, and perturbative triples with complete basis set (CCSD(T)/CBS) electronic energies for MBPT(2)/cc-pVTZ structures. Importantly, we have located a well-defined transition state for NN homolysis, in the initial RDX decomposition step, thereby obtaining a true barrier for this reaction. These calculations support the view that HONO elimination is preferred at STP over other proposed mechanisms, including NN homolysis, "triple whammy" and NONO isomerization. Indeed, our calculated values of Arrhenius parameters are in agreement with experimental findings for gas phase RDX decomposition. We also investigate a number of new pathways leading to breakdown of the intermediate formed by the initial HONO elimination, and find that NN homolysis in this intermediate has an activation energy barrier comparable with that computed for HONO elimination.

AB - The role of Cu and Zn ions in Alzheimer's disease is linked to the consequences of their coordination to the amyloid-beta (Abeta) peptide, i.e. to the modulation of Abeta aggregation and to the production of Reactive Oxygen Species (ROS), two central events of the so-called amyloid cascade. The role of both ions in Abeta aggregation is still controversial. Conversely the higher toxicity of the redox competent Cu ions (compared to the redox inert Zn ions) in ROS production is acknowledged. Thus the Cu ions can be considered as the main therapeutic target. Because Zn ions are present in higher quantity than Cu ions in the synaptic cleft, they can prevent detoxification of Cu by chelators unless they have an unusually high Cu over Zn selectivity. We describe a proof-of-concept study where the role of Zn on the metal swap reaction between two prototypical ligands and the Cu(Abeta) species has been investigated by several complementary spectroscopic techniques (UV-Vis, EPR and XANES). The first ligand has a higher Cu over Zn selectivity relative to the one of Abeta peptide while the second one exhibits a classical Cu over Zn selectivity. How Zn impacts the effect of the ligands on Cu-induced ROS production and Abeta aggregation is also reported.

These effects, however, are limited due to its poor aqueous stability and solubility. A hydrogel of 3% octadecyl randomly substituted polyacrylate (PAAC18) has been shown to provide high aqueous stability for curcumin under physiological conditions, offering a route for photodynamic therapy. In this study, the excited-state photophysics of curcumin in the PAAC18 hydrogel is investigated using a combination of femtosecond transient absorption and fluorescence upconversion spectroscopy. The transient absorption results reveal a multiexponential decay in the excited-state kinetics with fast (1 ps & 15 ps) and slow (110 ps & ~5 ns) components. The fast decay component exhibits a deuterium isotope effect with D2O in the hydrogel, indicating that the 15 ps decay component is attributable to excited-state intramolecular hydrogen atom transfer of curcumin in the PAAC18 hydrogel. In addition, solvent reorganisation of excited-state curcumin is investigated using multiwavelength femtosecond fluorescence upconversion spectroscopy. The results show that the dominant solvation response (tau = 0.08 ps) is a fast inertial motion owing to the presence of bulk-like water in the vicinity of the hydrophobic octadecyl substituents of the PAAC18 hydrogel. The results also show an additional response with longer time constants of 1 and 6 ps, which is attributable to translational diffusion of confined water molecules in the three-dimensional, cross-linking network of the octadecyl substituents of PAAC18. Overall, we show that excited-state intramolecular hydrogen atom transfer and solvent reorganisation are major photophysical events for curcumin in the PAAC18 hydrogel.

AB - A class of novel organic-inorganic hybrid lanthanide (Ln)-substituted Keggin-type borotungstates K4Na4H4[Ln2(gly)4(alpha-BW11O39)2].23H2O [Ln = Ce3+ (1), Pr3+ (2), Nd3+ (3), Sm3+ (4), Eu3+ (5), Tm3+ (6); gly = glycine] have been synthesized from the reaction of K8[BW11O39H].13H2O, NaAc.6H2O and Ln(NO3)3.6H2O by employing gly ligands as structure-stabilizing agents in the conventional aqueous solution system and structurally characterized by elemental analyses, IR spectroscopy, thermogravimetric (TG) analyses, powder X-ray diffraction (PXRD) and single crystal X-ray diffraction. The common prominent structural feature of isomorphic 1-6 is that all of them consist of two mono-Ln-substituted Keggin [Ln(alpha BW11O39)]6- fragments linked by four gly ligands, furnishing an intriguing dimeric assembly of the quadruple-gly-connective mono-Ln-substituted borotungstate, in which each carboxylic oxygen atom from gly ligands is bound to Ln3+ cations in the MU2-O or MU3-O mode. To the best of our knowledge, 1-6 represent the first examples of inorganic-organic hybrid Ln-substituted borotungstates functionalized by quadruple amino acid bridges. The solid-state photoluminescence properties of 3-5 have been determined at ambient temperature and the photoluminescence emission spectra exhibit the characteristic emission bands derived from Ln3+ centers. The thermostability of 1-6 has been studied and the thermal decomposition procedure of 3 has been comprehensively investigated with the assistance of variable-temperature PXRD patterns and variable temperature IR spectra. Furthermore, magnetic susceptibility measurements of 1, 2 and 4 have been conducted.

AB - Reactions of cyclopentadienyl transition-metal halide complexes [Cp*Mo(CO)3Cl], 1, and [CpFe(CO)2I], 2, (Cp = C5H5; Cp* = eta5-C5Me5) with borate ligands are reported. Treatment of 1 with [NaBt2] (Bt2 = dihydrobis(2-mercapto benzothiazolyl)borate) in toluene yielded [Cp*Mo(CO)2(C7H4S2N)], 3, and [Cp*Mo(CO)2(eta3-CH2C6H5)], 4, with a selective binding of toluene through C-H activation followed by orthometallation. Note that compound 4 is a structurally characterized toluene-activated molecule in which the metal is in eta3 coordination mode. Under similar reaction conditions, [NaPy2] (Py2 = dihydrobis(2 mercaptopyridyl)borate) produced only the mercaptopyridyl molybdenum complex [Cp*Mo(CO)2(C5H4SN)], 5, in good yield. On the other hand, when compound 2 was treated individually with [NaBt] (Bt = trihydro(2-mercapto-benzothiazolyl)borate) and [NaPy2] in THF, formation of the eta1-coordinated complexes [CpFe(CO)2(C7H4S2N)], 6, and [CpFe(CO)2(C5H4SN)], 7, was observed. The solid state molecular structures of compounds 3, 4, 6, and 7 have been established by single-crystal X-ray crystallographic analyses.

AB - The exploration of low-cost and highly efficient non-platinum electrocatalysts for the oxygen reduction reaction (ORR) is vital for renewable systems. Herein, we report a novel non-platinum electrocatalyst consisting of B and N separately co-doped graphitic carbon encapsulated Fe/Fe3C nanoparticles (BNGFe), which were synthesized from a facile method by adopting melamine, iron nitrate and boric acid as the precursors. In this synthesis, the N atoms in melamine first bond with the iron ions in iron nitrate, which could prevent the formation of BN covalent bonds during the subsequent pyrolysed process, resulting in the formation of effective B and N separately co-doped graphitic carbon encapsulated on the Fe/Fe3C nanoparticles. The synthetic BNGFe catalyst shows outstanding catalytic performance for ORR with an onset potential of 0.98 V (vs. RHE) and a high limiting diffusion current density, which could be comparable to the state of-the-art commercial Pt/C catalyst in alkaline electrolyte. PMID- 27711743 TI - Overview of the crystal chemistry of the actinide chalcogenides: incorporation of the alkaline-earth elements. AB - This review focuses on the results of exploratory syntheses of alkaline-earth metal actinide chalcogenides Ak-An-Q (Ak = Ba, Sr; An = Th, U; Q = S, Se, and Te). About thirty new compounds are described. Although the basic building blocks of their structures are usually AnQ6 octahedra and AkQ8 bicapped trigonal prisms, these are combined in diverse ways to afford eleven new structure types. The structures reconfirm the prevailing presence of An4+ in chalcogenides, although some of the compounds discovered are mixed An4+/An5+ systems, and a few contain only An5+. The tendency of the chalcogens to form Q-Q bonds is again evident from the presence of S-S single bonds and infinite Te-Te-Te linear chains. The latter possess interatomic distances of lengths greater than that of a Te-Te single bond but less than that of a Te-Te van der Waals interaction. Assignment of formal oxidation states in compounds containing these chains is arbitrary at best. Addition of metal atoms (M) affords quaternary structures, some of which show remarkable flexibility in the positions of the An and M atoms, and in such compounds the nature of the M elements influences directly the dimensionality of the resultant structure. The presence of adventitious oxygen, often from etching of the fused-silica tubes by oxyphilic An elements, results in new quintary compounds that show remarkable structural variations with change of M. The compounds discussed have shown transport and electronic structures that range from metallic-like to semiconducting. We find, with the exception of BaUSe3, when comparisons can be made that the values of the calculated band gaps are reasonably close but usually lower than the experimentally derived values. Thus the method used, in particular the HSE functional, has been generally successful on these 5f actinides. This is an important result because in the absence of suitable crystals, and hence experimental measurements, it still may be possible to offer credible predictions of some of the magnetic and electronic properties of the compounds.

AB - NbCl4 reacts with the dithioethers MeS(CH2)nSMe (n = 2 or 3), iPrS(CH2)2SiPr or o C6H4(CH2SEt)2 in a 1 : 1 molar ratio in CH2Cl2 or toluene over several days, to give red or orange, paramagnetic complexes, [NbCl4(dithioether)]. Their X-ray crystal structures confirm distorted octahedral geometries with chelating dithioether. MeS(CH2)2SMe, alone, also forms an [NbCl4{MeS(CH2)2SMe}2] complex based upon eight-coordinate Nb(iv) in a square antiprismatic geometry. Similar six-coordinate cis-[NbCl4(diselenoether)] are formed by MeSe(CH2)nSeMe (n = 2 or 3) and nBuSe(CH2)3SenBu. The monodentate ligands Me2S, Me2Se and nBu2Se form [NbCl4(R2E)2] (E = S, Se) which are unstable in solution, losing R2E to form complexes with a 1 : 1 stoichiometry, which are shown to be diamagnetic dimers, [(Me2E)Cl3Nb(MU-Cl)2NbCl3(Me2E)], with single Nb-Nb sigma-bonds. Tellurium ligands tend to decompose in these reactions, but reaction at room temperature of Me2Te and NbCl4 formed [NbCl4(Me2Te)2], the X-ray structure of which revealed an eight-coordinate dimer, [Nb2Cl4(MU-Cl)4(Me2Te)4]. The new complexes have been characterised by microanalysis, IR, UV-visible spectroscopy and magnetic measurements. X-ray crystal structures are reported for [NbCl4(L-L)] (L-L = MeS(CH2)nSMe, n = 2 or 3, iPrS(CH2)2SiPr, o-C6H4(CH2SEt)2, MeSe(CH2)3SeMe), [Nb2Cl8(Me2Te)4], [Nb2Cl8(Me2S)2] and [Nb2Cl8(Me2Se)2]. The complexes are very sensitive to moisture and dioxygen, and some also readily undergo C-E bond cleavage. Two ligand fragmentation products were identified -[Nb2Cl4(MU S)2{MeS(CH2)3SMe}2] and [Nb2Cl4(MU-Se)2{o-C6H4(CH2)2Se}4]. X-ray crystal structures are also reported for the oxidation/hydrolysis products [NbOCl3(Me2S)] and [NbOCl3{MeS(CH2)2SMe}]. PMID- 27711745 TI - Four new 3D metal-organic frameworks constructed by the asymmetrical pentacarboxylate: gas sorption behaviour and magnetic properties. AB - By using an asymmetrical rigid pentacarboxylic acid ligand, 2,4-di(3',5' dicarboxylphenyl)benzoic acid (H5L), four new three-dimensional (3D) metal organic frameworks (MOFs), namely {[Cu2(HL)(H2O)2].2DMF.2H2O}n (1), {[Co2(L)(DMA)].H2N(Me)2}n (2), {[Co2(L)(H2O)].H2N(Me)2}n (3), {[Mn2(L)(DMF)(H2O)].H2N(Me)2}n (4), were solvothermally synthesized. H5L in 1-4 shows different coordination modes and can easily form various metal clusters (secondary building units, SBUs) in the final structures. 1 is a 3D porous framework with a (4,4)-connected pts topology based on the [Cu2(COO)4] paddlewheel SBU, wherein six SBUs are connected by twelve HL4- to get an unprecedented Cu12 hendecahedron nanocage. 2-4 possess similar dinuclear [M2(COO)5] SBUs (M = Co, Mn), which are further extended by L5- to give rise to 3D frameworks with the uncommon (5,5)-connected nia-5,5-P21/c and bnn topologies. In addition, the desolvated framework of 1 contains polar channels decorated with uncoordinated carboxylate groups, leading to selective adsorption for CO2 over CH4 at 195, 273 and 298 K. Moreover, the magnetic properties of 1-4 show that there exist antiferromagnetic interactions between metal ions. PMID- 27711746 TI - Highly sensitive and selective fluorescent probes for Hg2+ in Ag(i)/Cu(ii) 3D supramolecular architectures based on noncovalent interactions. AB - Three novel metal-organic assemblies (MOAs), namely, [Ag(2,4'-Hpdc)(4,4'-bpy)]n (1), [Ag(2,2'-Hpdc)(4,4'-bpy)0.5]n (2), and [Cu(2,2'-Hpdc)2(1,4-bib)]n (3) [2,4' H2pdc = 2,4'-biphenyldicarboxylic acid; 2,2'-H2pdc = 2,2'-biphenyldicarboxylic acid; 4,4'-bpy = 4,4'-bipyridine; 1,4-bib = 1,4-bis(1-imidazolyl)benzene] have been hydrothermally synthesized by using mixed ligands and characterized by single crystal X-ray diffraction, infrared (IR), elemental analysis and thermogravimetric analysis (TGA). The crystal structures of the three compounds indicate that the hydrogen bonding (C-HO and C-Hpi) and pipi stacking interactions play critical roles in the formation of an extended supramolecular array. The combination of C-Hpi and pipi stacking interactions endow 1 with a 3D network. 2 displays a rare 3D structure with a unique 1D structure based on an eight-membered {Ag2C2O4} ring and compound 3 shows a 1D chain structure, which is propagated to form an extended 3D structure only by C-Hpi hydrogen bonding. The two Ag(i)-compounds display blue emissions in the solid state at 298 K and 77 K. More significantly, compound 1 shows excellent selectivity, fast detection time (<5 min), and high sensitivity (detection limit, 9.63 nM) for Hg2+ ions in aqueous solution due to a great enhancement of 1-luminescence, which can be attributed to Hg2+ cation binding by a non-coordinated carboxyl group efficiently. This is a rare example of Hg2+ detection in aqueous solution based on luminescent silver MOAs. In addition, adsorption spectra reveal the semiconductive nature (2.76 eV for 2, but not detected for 1), thus the role of the AgAg interaction in controlling the performance of the semiconductor properties is highlighted.

AB - Crystal structures and photophysical properties (IR and UV-vis-NIR) of two compounds, [C(NH2)3]5[Eu(DOTP)].12.5H2O and K5[Eu(DOTP)].11H2O (DOTP = 1,4,7,10 tetraazacyclododecane-1,4,7,10-tetrakis (methylenephosphonic acid)), were determined. The DOTP ligand is bonded to Eu3+via four O and four N atoms, filling thus eight coordination sites of Eu3+. The experimental structures of two [K4Eu(DOTP)]- clusters were used as a starting point for theoretical ab initio calculations based on a multireference wavefunction approach. Positions of the energy levels of the 4f6 configuration of the Eu3+ ion have been calculated and compared with those derived from the experimental spectra. This enabled us to tentatively assign energy levels of the Eu3+ ion. The relationship between calculated energies of excited states and Eu-N and Eu-O bond lengths was discussed with respect to the nephelauxetic effect.

AB - Bis(glycolato)copper(ii) [Cu(HOCH2CO2)2] shows a structural phase transition around 220 K under cooling and 270 K under heating, and ferromagnetic ordering at 1.1 K. Deuterium substitution of the hydroxyl groups in it induced a large shift in the structural transition temperature while no shift in the ferromagnetic transition temperature took place.

AB - Copper complexes have anti-inflammatory activity in the treatment of inflammation associated with rheumatoid arthritis (RA). The preferred route of administration is through the skin, so the rate of dermal absorption and bioavailability of copper is important. Based on previous studies, 3-amino-N-(pyridin-2-ylmethyl) propanamide, [H(56)NH2], was designed as a potential chelator of copper. The stability constant measurements revealed that MLH-1 is the most stable species at the physiological pH of 7.4. The X-ray crystal structure of this species was solved and copper was found in a rectangular pyramidal geometry. The ligand occupied three coordination sites while bridging chloride linked copper ions together in a chain. The ligand bound to the metal ion through the pyridyl nitrogen, the amide nitrogen and the terminal amino group. Spectroscopic studies confirmed that this structure persisted in aqueous solution. Octanol/water partition coefficients and Franz cell permeation studies showed that [H(56)NH2] is able to promote the dermal absorption of Cu(ii).

AB - The diffusion of a particle is slowed as it moves close to a surface. We identify the conditions under which this hindered diffusion is significant and show that is strongly dependant on the sizes of both the particle and the target. We focus particularly on the transport of nano-particles to a variety of targets including a planar surface, a sphere, a disc and a wire, and provide data which allows the frequency of impacts to be inferred for a variety of experimental conditions. Equations are given to estimate the particle fluxes and we explain literature observations reported on the detected frequency of impacts. Finally we observe a drastic effect on the calculation of the mean first passage time of a single particle impacting a sub-micron sized target, showing the importance of this effect in biological systems.

AB - Ruthenium (Ru) nanoparticles (NPs) are supported on nitrogen-doped porous carbon (NPC) derived from metal-organic-framework (MOF) ZIF-8 for the first time. NPC is prepared by the direct carbonization of ZIF-8 crystals, which not only retains the original morphology of ZIF-8 but also provides a high surface area and stable chemical-physical properties. Ru NPs were supported by different methods. Four types of Ru-based catalysts are tested in the selective hydrogenation of p chloronitrobenzene (p-CNB) and p-bromonitrobenzene (p-BNB) to haloanilines. Different catalytic activities and selectivities are obtained through these catalysts. After the screening of the catalysts and reaction conditions, high conversion and selectivity were obtained. The hydrogen pressure is limited to 1.5 MPa, which is much lower than most previous reports, and the dehalogenation reaction is restricted to a very low level. Furthermore, the dehalogenation properties of the Ru/NPC catalysts are also studied. PMID- 27711754 TI - Characteristics and reactivity of ruthenium-oxo complexes. AB - In this perspective, we have surveyed the synthetic procedure, characteristics, and reactivity of high-valent ruthenium-oxo complexes. The ruthenium-oxo complexes have served as ideal species to elucidate the characteristics of metal oxo complexes in terms of not only geometrical and electronic structures but also oxidation reactivity and mechanisms of oxidation reactions. Due to the high stability and excellent reversibility of redox processes, ruthenium-oxo complexes have provided significant mechanistic insights into the oxidation of organic compounds including alcohols, alkenes, and alkanes and also water on the basis of detailed kinetic analysis.

AB - Effective separation of lithium isotopes is of strategic value which attracts growing attention worldwide. This study reports a new class of macrocyclic ligand decorated ordered mesoporous silica (OMS) with large-pore and short-channel characteristics, which holds the potential to effectively separate lithium isotopes in aqueous solutions. Initially, a series of benzo-15-crown-5 (B15C5) derivatives containing different electron-donating or -withdrawing substituents were synthesized. Extractive separation of lithium isotopes in a liquid-liquid system was comparatively studied, highlighting the effect of the substituent, solvent, counter anion and temperature. The optimal NH2-B15C5 ligands were then covalently anchored to a short-channel SBA-15 OMS precursor bearing alkyl halides via a post-modification protocol. Adsorptive separation of the lithium isotopes was fully investigated, combined with kinetics and thermodynamics analysis, and simulation by using classic adsorption isotherm models. The NH2-B15C5 ligand functionalized OMSs exhibited selectivity to lithium ions against other alkali metal ions including K(i). Additionally, a more efficient separation of lithium isotopes could be obtained at a lower temperature in systems with softer counter anions and solvents with a lower dielectric constant. The highest value separation factor (alpha = 1.049 +/- 0.002) was obtained in CF3COOLi aqueous solution at 288.15 K. Moreover, theoretical computation based on the density functional theory (DFT) was performed to elucidate the complexation interactions between the macrocyclic ligands and lithium ions. A suggested mechanism involving an isotopic exchange equilibrium was proposed to describe the lithium isotope separation by the functionalized OMSs.

AB - The employment of a new Schiff base ligand, 2-{[(2-hydroxy-3 methoxybenzyl)imino]methyl}naphthalen-1-ol (H2L), in 4f-metal chemistry has led to the formation of seven new isostructural lanthanide(iii) complexes. More specifically the 1 : 1 reaction of Ln(NO3)3.6H2O and H2L in ethanol in the presence of 3 equivalents of pyridine yielded seven dinuclear complexes of compositions [Ln2L2(NO3)2(C2H5OH)2].0.5py (Ln = Eu (1), Gd (2), Tb (3), Dy (4), Ho (5), Er (6), Yb (7); py = pyridine). The structures of the isomorphous complexes 1-7 were determined by single-crystal X-ray crystallography. X-ray crystallography data reveal that each compound is neutral, and contains two doubly-deprotonated ligands, two chelated nitrates and two coordinated ethanol molecules. The two LnIII atoms in 1-7 are doubly bridged by the two phenolato oxygen atoms of two L2- ligands. Each of the two lanthanide ions is eight coordinated and possesses distorted dodecahedron geometry. Dc magnetic susceptibility studies in the 2-300 K range reveal probably a weak antiferromagnetic interaction for 2, 3 and 6, and a ferromagnetic interaction at low temperature for 4 and 5. Complexes 4 and 5 show slow magnetic relaxation behavior. The Ueff for 4 of 66.7 K is a relatively high value among the reported Dy2 SMMs. Complex 5 is a very rare example of a Ho2 compound which exhibits slow magnetic relaxation.

AB - Non-refractory submicron (NR-PM1) aerosols were measured during the late winter period (February-March) via an Aerodyne High Resolution Time of Flight Aerosols Mass Spectrometer (HR-ToF-AMS) along with Black Carbon (BC) and trace gasses in an industrial city, Kanpur, situated in the Gangetic Plain (GP) of India. The composition of NR-PM1 aerosols was dominated by organics (54%), followed by inorganics (36%), and BC (10%). Source apportionment via Positive Matrix Factorization (PMF) of AMS measured organic aerosols (OAs) revealed 6 factors. Factors are identified as 2 types of oxidized organic aerosols (OOAs), 2 types of biomass burning organic aerosols (BBOAs), freshly emitted hydrocarbon-like organic aerosols (HOAs) and oxygenated primary organic aerosols (OPOAs). A substantial increase in relative OOA contributions (200%) and O/C ratio (26%) has been observed from the high loading events (HLE) to the low loading events (LLE). Back trajectory analysis indicated that the study location received contributions from regional and long-range transported aerosols. OA composition and evolution during this study period were also very different from those observed during a fog influenced peak winter period of December-January. This is the first study to present detailed aerosol composition during the late winter period in India highlighting the changes in OA composition and chemistry within the same winter season. PMID- 27711758 TI - Crystal, electronic, and magnetic structures of M2AgF4 (M = Na-Cs) phases as viewed from the DFT+U method. AB - Theoretical investigations of the magneto-structural correlations of M2AgF4 (M = Na-Cs) compounds show that they adopt two polymorphs, the layered perovskite and post-perovskite structures, which differ greatly in the connectivity of the Ag/F sub-lattice and hence in their magnetic properties. With the use of the DFT+U method, the relative stabilities of various M2AgF4 phases were established and the collective JT effect within the Ag/F sub-lattice of these systems was modelled. Calculations show that for all studied stoichiometries, the preferred scenario of the collective JT effect in the layered perovskite phase corresponds to an antiferrodistortive order of elongated octahedra, which leads to 2D ferromagnetic coupling, in agreement with the experimental findings for the M = Cs, and Rb systems. The layered perovskite phase is found to be progressively destabilized with respect to the post-perovskite structure when moving from Cs to Na, again in agreement with the experimental findings. Our results strongly indicate that the layered polymorph of K2AgF4 should not exhibit a ferrodistortive order of compressed octahedra, which contradicts the previous experimental results. PMID- 27711759 TI - A computational study of doped olivine structured Cd2GeO4: local defect trapping of interstitial oxide ions. AB - Computational modelling techniques have been employed to investigate defects and ionic conductivity in Cd2GeO4. We show due to highly unfavourable intrinsic defect formation energies the ionic conducting ability of pristine Cd2GeO4 is extremely limited. The modelling results suggest trivalent doping on the Cd site as a viable means of promoting the formation of the oxygen interstitial defects. However, the defect cluster calculations for the first time explicitly suggest a strong association of the oxide defects to the dopant cations and tetrahedral units. Defect clustering is a complicated phenomenon and therefore not trivial to assess. In this study the trapping energies are explicitly quantified. The trends are further confirmed by molecular dynamic simulations. Despite this, the calculated diffusion coefficients do suggest an enhanced oxide ion mobility in the doped system compared to the pristine Cd2GeO4.

AB - The synthesis, single-crystal structure characterization and detailed magnetic study of a homometallic hexanuclear CuII cluster [Cu6(MU3-OH)2(ppk)6(H2O)2(NO3)4] (1) and a three-dimensional (3D) compound [{MnCu2(dpkO2H)2(dpkO2)N3}.(NO3).H2O]n (2) (ppk = phenyl-2-pyridyl ketoxime; dpk = di-2-pyridyl ketone) consisting of heterometallic MnII-CuII hexanuclear cores as secondary building units are reported in this paper. In compound 1, two symmetry-related Cu3 triangles consisting of a hydroxido-bridged trinuclear unit, [Cu3(MU3 OH)(ppk)3(H2O)(NO3)]+, are assembled through nitrate bridging giving rise to the homometallic Cu6 cluster. Compound 2 contains heterometallic {MnCu} cores, which are further connected to each other through an azido bridging ligand in all the crystallographic directions, resulting in a 3D metal-organic framework. Construction of such a heterometallic 3D framework from {MnCu} units is until now, unknown. Magnetic studies of both 1 and 2 were performed in detail and both compounds show dominant antiferromagnetic interaction in the respective clusters. Compound 1 reveals significant spin frustration and anti-symmetric exchange interaction in the trinuclear cores, with a significantly high value of Jav (-655 cm-1). Furthermore, compound 2 exhibits a dominant antiferromagnetic interaction, which is also supported by an extensive magneto-structural correlation which considers the different magnetic pathways.

AB - By using 1-methyl-4-(carbomethoxy)pyridinium (MCMP+) as counterions, two iodoargentate hybrids, 1D [MCMP][AgI2] (1) and 3D [MCMP][Ag3I4] (2) have been synthesized and they exhibit rare electron transfer photochromism with a fast response rate, a wide response range and a long-lived charge-separated state in iodometallate systems. Noteworthily, the marked differences in the structure and photochromic performance of 1 and 2 are largely ascribed to the different aggregating behavior of electron-deficient MCMP+ counterions (C-HO hydrogen bonded trimer in 1 and pi-pi/C-Hpi chain in 2).

AB - Inclusion complexes of ferrocene (Fc) with cucurbit[n]urils (n = 7, 8) have been prepared via a rapid microwave-assisted hydrothermal approach. Solids were isolated and characterised by elemental analysis, powder X-ray diffraction (PXRD), spectroscopic, and thermoanalytical methods. The UV-Vis spectra support the presence of Fc in Fc@CB7 and a mixture of Fc and ferrocenium ions in Fc@CB8. Partial oxidation of Fc to Fc+ takes place in situ mainly due to the presence of acid of crystallisation in CB8. On the basis of PXRD, the complex Fc@CB8 is classified into an isostructural series that is formed by several CB8-containing compounds that crystallise in the space group I41/a and have similar unit cell dimensions and CB8 packing motifs. The FT-IR and Raman spectra of Fc@CB7 are compared with those of the CB7 host and the Fc guest starting materials, revealing significant frequency shifts of some Fc-centered vibrational modes upon complexation. Blueshifts of the Fe-Cp stretching and ring tilt bands are attributed to encapsulation of Fc monomers in a constrained environment, leading to restricted motion effects and/or a change in the Fc conformation from staggered to eclipsed. The absence of comparable shifts for Fc@CB8 point to a weaker host-guest interaction as a consequence of the larger cavity size. The different host-guest interactions are also evident through a comparison of the 13C{1H} CP MAS NMR spectra. Thermogravimetric analysis for the inclusion compounds reveals that sublimation of Fc is inhibited by molecular encapsulation to the extent that oxidative decomposition of the organoiron species takes place concurrently with cucurbituril decomposition, leading to the formation of hematite, alpha-Fe2O3. PMID- 27711764 TI - Increasing the triplet lifetime and extending the ground-state absorption of biscyclometalated Ir(iii) complexes for reverse saturable absorption and photodynamic therapy applications. AB - The synthesis, photophysics, reverse saturable absorption, and photodynamic therapeutic effect of six cationic biscyclometalated Ir(iii) complexes (1-6) with extended pi-conjugation on the diimine ligand and/or the cyclometalating ligands are reported in this paper. All complexes possess ligand-localized 1pi,pi* absorption bands below 400 nm and charge-transfer absorption bands above 400 nm. They are all emissive in the 500-800 nm range in deoxygenated solutions at room temperature. All complexes exhibit strong and broad triplet excited-state absorption at 430-800 nm, and thus strong reverse saturable absorption for ns laser pulses at 532 nm. Complexes 1-4 are strong reverse saturable absorbers at 532 nm, while complex 6 could be a good candidate as a broadband reverse saturable absorber at 500-850 nm. The degree of pi-conjugation of the diimine ligand mainly influences the 1pi,pi* transitions in their UV-vis absorption spectra, while the degree of pi-conjugation of the cyclometalating ligand primarily affects the nature and energies of the lowest singlet and emitting triplet excited states. However, the lowest-energy triplet excited states for complexes 3-6 that contain the same benzo[i]dipyrido[3,2-a:2',3'-c]phenazine (dppn) diimine ligand but different cyclometalating ligands remain the same as the dppn ligand-localized 3pi,pi* state, which gives rise to the long-lived, strong excited-state absorption in the visible to the near-IR region. All of the complexes exhibit a photodynamic therapeutic effect upon visible or red light activation, with complex 6 possessing the largest phototherapeutic index reported to date (>400) for an Ir(iii) complex. Interactions with biological targets such as DNA suggest that a novel mechanism of action may be at play for the photosensitizing effect. These Ir(iii) complexes also produce strong intracellular luminescence that highlights their potential as theranostic agents.

Relying on a simplistic model of RNA guided DNA binding and cleavage, this molecular toolbox has found application in nearly every branch of biological sciences. The story of CRISPR-Cas9 is one of discovery and development where a component of bacterial adaptive immunity has been harnessed to address important biological questions using significant inputs from physicochemical structure-function studies.

PMID- 27711768 TI - Three and four coordinate Fe carbodiphosphorane complexes. AB - Carbodiphosphoranes (CDPs) are a family of divalent carbon ligands that are known for their exceptional electron donor properties. Herein, the preparation and reactivity of a family of three and four co-ordinate Fe carbodiphosphorane complexes is described. Hexaphenylcarbodiphosphorane (HCDP) [1] is shown to react with FeCl2(PPh3)2 to form the three coordinate adduct Fe(HCDP)Cl2 [2], which is equilibrium with its four coordinate dimer. Reaction of [2] with two equivalents of benzyl Grignard yields the corresponding dialkyl complex (HCDP)FeBn2 [3]. Combination of [2] with LiHMDS results in salt metathesis and the formation of the monosilylated derivative Fe(HCDP)Cl(N(SiMe3)2) [4]. Subsequent anion exchange leads to the three coordinate Fe(HCDP)(OTf)(N(SiMe3)2) [5] which was characterized crystallographically and in solution. PMID- 27711766 TI - Cyclometallated iridium complexes inducing paraptotic cell death like natural products: synthesis, structure and mechanistic aspects. AB - Six mononuclear Ir complexes (1-6) using polypyridyl-pyrazine based ligands (L1 and L2) and {[cp*IrCl(MU-Cl)]2 and [(ppy)2Ir(MU-Cl)]2} precursors have been synthesised and characterised. Complexes 1-5 have shown potent anticancer activity against various human cancer cell lines (MCF-7, LNCap, Ishikawa, DU145, PC3 and SKOV3) while complex 6 is found to be inactive. Flow cytometry studies have established that cellular accumulation of the complexes lies in the order 2 > 1 > 5 > 4 > 3 > 6 which is in accordance with their observed cytotoxicity. No changes in the expression of the proteins like PARP, caspase 9 and beclin-1, Atg12 discard apoptosis and autophagy, respectively. Overexpression of CHOP, activation of MAPKs (P38, JNK, and ERK) and massive cytoplasmic vacuolisation collectively suggest a paraptotic mode of cell death induced by proteasomal dysfunction as well as endoplasmic reticulum and mitochondrial stress. An intimate relationship between p53, ROS production and extent of cell death has also been established using p53 wild, null and mutant type cancer cells.

AB - An amidinato-phosphino ligand ArN[double bond, length as m-dash]C(R)NH(o Ph2PC6H4) (Ar = 2,4,6-Me3C6H2, R = Ph (1); Ar = 2,6-iPr2C6H3, R = Ph (2); Ar = 2,6-iPr2C6H3, R = tBu (3)) was prepared. The ligand reacted with CrCl3(THF)3 to yield the N,P-chelation complex [ArNHC(R)[double bond, length as m-dash]N(o Ph2PC6H4)]CrCl3(THF) (4-6), and the ligand's lithium salt ArN[double bond, length as m-dash]C(R)N(o-Ph2PC6H4)Li reacted with the respective CrCl3(THF)3 and CrCl2(THF)2 to give the N,N,P-chelation complexes [ArN[double bond, length as m dash]C(R)N(o-Ph2PC6H4)]CrCl2(THF) (7-8) and {[ArN[double bond, length as m dash]C(R)N(o-Ph2PC6H4)]Cr(MU-Cl)}2 (9-11). Complexes 1-11 were characterized by IR, NMR (for 1-3), EPR (for 4-11) spectroscopy and CHN elemental analysis, of which 3, 5, 8, and 11 were further studied by X-ray crystallography. Upon activation with an organoaluminum cocatalyst, complexes 4-6 were all catalytically active in ethylene tri-/tetramerization along with ethylene polymerization, and complexes 7-11 functioned as well but in ethylene polymerization. The correlation between the structure and the catalytic properties of the catalyst system is discussed. PMID- 27711771 TI - Pseudocontact shifts from mobile spin labels. AB - This paper presents a detailed analysis of the pseudocontact shift (PCS) field induced by a mobile spin label that is viewed as a probability density distribution with an associated effective magnetic susceptibility anisotropy. It is demonstrated that non-spherically symmetric density can lead to significant deviations from the commonly used point dipole approximation for the PCS. Analytical and numerical solutions are presented for the general partial differential equation that describes the non-point case. It is also demonstrated that it is possible, with some reasonable approximations, to reconstruct paramagnetic centre probability distributions from the experimental PCS data.

AB - The condensation reactions of 2-formylindole (1) or 2-formylphenanthro[9,10 c]pyrrole (2) with various aromatic amines afforded the corresponding phenyl or phenanthrene ring fused mono-/bis-iminopyrrole ligand precursors 3-8, which, upon reaction with BPh3 in an appropriate molar ratio, led to the new mono- and diboron chelate compounds Ph2B[NC8H5C(H)[double bond, length as m-dash]N-2,6-Ar] (Ar = 2,6-iPr2C6H39; C6H510), Ph2B[(NC8H5C(H)[double bond, length as m-dash]N)2 1,4-C6H4]BPh211, Ph2B(NC16H9C(H)[double bond, length as m-dash]N-Ar) (Ar = 2,6 iPr2C6H312; C6H513), and Ph2B[(NC16H9C(H)[double bond, length as m-dash]N)2-1,4 C6H4]BPh214, respectively. Boron complexes 12-14, containing a phenanthrene fragment fused to the pyrrolyl C3-C4 bond, are highly fluorescent in solution, with quantum efficiencies of 37%, 61% and 58% (in THF), respectively, their emission colours ranging from blue to orange depending on the extension of pi conjugation. Complexes 9-11, containing a benzene fragment fused to the pyrrolyl C4-C5 bond, are much weaker emitters, exhibiting quantum efficiencies of 10%, 7% and 6%, respectively. DFT and TDDFT calculations showed that 2,6-iPr2C6H3N substituents or, to a smaller extent, the indolyl group prevent a planar geometry of the ligand in the excited state and reveal the existence of a low energy weak band in all the indolyl complexes, which is responsible for the different optical properties. Non-doped single-layer light-emitting diodes (OLEDs) were fabricated with complexes 9-14, deposited by spin coating, that of complex 13 revealing a maximum luminance of 198 cd m-2.

PMID- 27711774 TI - 1001 lights: luciferins, luciferases, their mechanisms of action and applications in chemical analysis, biology and medicine. AB - Bioluminescence (BL) is a spectacular phenomenon involving light emission by live organisms. It is caused by the oxidation of a small organic molecule, luciferin, with molecular oxygen, which is catalysed by the enzyme luciferase. In nature, there are approximately 30 different BL systems, of which only 9 have been studied to various degrees in terms of their reaction mechanisms. A vast range of in vitro and in vivo analytical techniques have been developed based on BL, including tests for different analytes, immunoassays, gene expression assays, drug screening, bioimaging of live organisms, cancer studies, the investigation of infectious diseases and environmental monitoring. This review aims to cover the major existing applications for bioluminescence in the context of the diversity of luciferases and their substrates, luciferins. Particularly, the properties and applications of d-luciferin, coelenterazine, bacterial, Cypridina and dinoflagellate luciferins and their analogues along with their corresponding luciferases are described. Finally, four other rarely studied bioluminescent systems (those of limpet Latia, earthworms Diplocardia and Fridericia and higher fungi), which are promising for future use, are also discussed. PMID- 27711775 TI - Dehalogenation of chloroalkanes by nickel(i) porphyrin derivatives, a computational study. AB - The nickel(i) octaethylisobacteriochlorin anion ([OEiBCh-Ni(I)]-) is commonly used as a synthetic model of cofactor F430 from Methyl-Coenzyme M Reductase. In this regard, experimental studies show that [OEiBCh-Ni(I)]- can catalyze dehalogenation of aliphatic halides in DMF solution by a highly efficient SN2 reaction. To better understand this process, we constructed theoretical models of the dehalogenation of chloromethane by a simple nickel(i) isobacteriochlorin anion and compared its reactivity with that of similar Ni(I) complexes with other porphyrin-derived ligands: porphyrin, chlorin, bactreriochlorin, hexahydroporphyrin and octahydroporphyrin. Our calculations predict that all of the porphyrin derivative's model reactions proceed through low-spin complexes. Relative to the energy of the separate reactants the theoretical activation energies (free-energy barriers with solvation corrections) for the dehalogenation of chloromethane are similar for all of the porphyrin derivatives and range for the different functionals from 10-15 kcal mol-1 for B3LYP to 5-10 kcal mol-1 for M06-L and to 13-18 kcal mol-1 for omegaB97X-D. The relative free energies of the products of the dehalogenation step, L-Ni-Me adducts, have a range from -5 to -40 kcal mol-1 for all functionals; generally becoming more negative with increasing saturation of the porphyrin ligand. Moreover, no significant differences in the theoretical chlorine kinetic isotope effect were discernable with change of porphyrin ligand. PMID- 27711776 TI - Thermodynamics of biphasic lanthanide extraction by tripodal diglycolamide: a solution calorimetry study. AB - Isothermal titration calorimetry was employed for the direct measurement of the enthalpy of extraction (DeltaHextr) of Eu(NO3)3 by using a tripodal diglycolamide (T-DGA) ligand dissolved in n-dodecane containing 5% (v/v) 2-decanol. The enthalpy of extraction obtained by titration calorimetry was in good agreement with the enthalpy of extraction calculated from the temperature dependence of the distribution coefficients by using the van't Hoff equation. The Gibbs free energy and the entropy of extraction (DeltaGextr and DeltaSextr) for the extraction of Eu(NO3)3 by T-DGA were also obtained by solvent extraction experiments. The complexation of Eu3+ with T-DGA in a mixture of acetonitrile/nitric acid was also studied by spectrophotometry and calorimetry to determine the stability constants and the enthalpy of complexation (DeltaHcomp) for the Eu3+/T-DGA complexes in a single phase. The enthalpy of complexation, though obtained in a solvent different from that in the solvent extraction, allows a rough estimate of the enthalpy of phase transfer of the Eu3+/T-DGA complexes from the aqueous phase to the organic phase.

AB - A series of dimethyldihydropyrene (DHP)-pyridyl photochromic derivatives has been synthesized and its photochemical behaviour characterized by spectroscopic and electrochemical methods. The corresponding noncovalently-linked electron donor acceptor complexes have been isolated. They combine the DHP-pyridyl ligand as a donor and the zinc(ii) tetraphenylporphyrin as acceptor. Such association allowed to explore the efficiency of dative bonds to monitor the interactions between the two units. PMID- 27711778 TI - Interference stabilization of autoionizing states in molecular N2 studied by time and angular-resolved photoelectron spectroscopy. AB - An autoionizing resonance in molecular N2 is excited by an ultrashort XUV pulse and probed by a subsequent weak IR pulse, which ionizes the contributing Rydberg states. Time- and angular-resolved photoelectron spectra recorded with a velocity map imaging spectrometer reveal two electronic contributions with different angular distributions. One of them has an exponential decay rate of 20 +/- 5 fs, while the other one is shorter than 10 fs. This observation is interpreted as a manifestation of interference stabilization involving the two overlapping discrete Rydberg states. A formalism of interference stabilization for molecular ionization is developed and applied to describe the autoionizing resonance. The results of calculations suggest, that the effect of the interference stabilization is facilitated by rotationally-induced couplings of electronic states with different symmetry.

PMID- 27711780 TI - Synthesis of three series of ruthenium tris-diimine complexes containing acridine based pi-extended ligands using an efficient "chemistry on the complex" approach. AB - The preparation and characterization of three series of novel ruthenium(ii) complexes are reported, each series differing by the nature of the ancillary ligands (2,2'-bipyridine - bpy, 1,10-phenanthroline - phen or 1,4,5,8 tetraazaphenanthrene - TAP). The third ligand was either the heptacyclic heterocycle dipyrido[3,2-a:2',3'-c]quinolino[3,2-h]phenazine (dpqp) substituted at position 12 by an hydroxyl (oxo), 2,2-dimethoxyethylamine (DMEA) or halogeno (Cl or Br) substituent, or the octacyclic dipyrido[3,2-a:2',3'-c]pyrido[2,3,4 de]quinolino[3,2-h]phenazine (dppqp), prepared by a multi-step "chemistry on the complex" strategy from [RuL2(oxo-dpqp)](PF6)2. The three steps, halogenation, substitution by a dimethoxyethylamino group and cyclization in trifluoroacetic acid, were performed in reasonable to high yields depending on the nature of the ancillary ligands. Isolation and purification processes were facilitated by the ability to switch the solubility of the complex from aqueous to organic solvents, depending on the counter-ion. All new complexes were fully characterized; in particular their absorption properties were compared by UV-vis spectroscopy. Finally, pi-stacking properties induced by these extended ligands were studied by 1H NMR studies and quantum chemical calculations.

AB - The characterization of plasma and atomic radical parameters along with the energy influx from plasma to the substrate during plasma enhanced chemical vapor deposition (PECVD) of Si quantum dot (QD) films is presented and discussed. In particular, relating to the Si QD process optimization and control of film growth, the necessity to control the deposition environment by inducing the effect of the energy of the key plasma species is realized. In this contribution, we report dual frequency PECVD processes for the low-temperature and high-rate deposition of Si QDs by chemistry and energy control of the key plasma species. The dual frequency plasmas can effectively produce a very high plasma density and atomic H and N densities, which are found to be crucial for the growth and nucleation of QDs. Apart from the study of plasma chemistry, the crucial role of the energy imparted due to these plasma activated species on the substrate is determined in light of QD formation. Various plasma diagnostics and film analysis methods are integrated to correlate the effect of plasma and energy flux on the properties of the deposited films prepared in the reactive mixtures of SiH4/NH3 at various pressures. The present results are highly relevant to the development of the next-generation plasma process for devices that rely on effective control of the QD size and film properties.

AB - A method for the synthesis of non-aggregated and highly uniform Eu3+ doped NaGd(MoO4)2 nanoparticles is reported for the first time. The obtained particles present tetragonal structure, ellipsoidal shape and their size can be varied by adjusting the experimental synthesis parameters. These nanoparticles, which were coated with citrate anions and functionalised with PLL, have also been developed in order to improve their colloidal stability in physiological medium (2-(N morpholino)ethanesulfonic acid, MES). A study of the luminescent dynamics of the samples as a function of the Eu doping level has been conducted in order to find the optimum nanophosphors, whose magnetic relaxivity and cell viability have also been evaluated for the first time for this system, in order to assess their suitability as multifunctional probes for optical (in vitro) and magnetic bioimaging applications. PMID- 27711784 TI - Visualization of bond rearrangements in acetylene using near single-cycle laser pulses. AB - The migration of hydrogen atoms resulting in the isomerization of hydrocarbons is an important process which can occur on ultrafast timescales. Here, we visualize the light-induced hydrogen migration of acetylene to vinylidene in an ionic state using two synchronized 4 fs intense laser pulses. The first pulse induces hydrogen migration, and the second is used for monitoring transient structural changes via Coulomb explosion imaging. Varying the time delay between the pulses reveals the migration dynamics with a time constant of 54 +/- 4 fs as observed in the H+ + H+ + CC+ channel. Due to the high temporal resolution, vibrational wave packet motions along the CC- and CH-bonds are observed. Even though a maximum in isomerization yield for kinetic energy releases above 16 eV is measured, we find no indication for a backwards isomerization - in contrast to previous measurements. Here, we propose an alternative explanation for the maximum in isomerization yield, namely the surpassing of the transition state to the vinylidene configuration within the excited dication state. PMID- 27711785 TI - The effect of imidazole on the enhancement of gadolinium-porphyrin phosphorescence at room temperature. AB - A mechanism for the enhanced room-temperature phosphorescence (RTP) of gadolinium coordinated hematoporphyrin monomethyl ether (Gd-HMME) in the presence of imidazole and free gadolinium ions (Gd3+) is revealed. Imidazole, the molten solvent used in the synthesis of Gd-HMME, was effective in enhancing the Gd-HMME RTP. In the presence of imidazole, further enhancement of the Gd-HMME RTP was observed upon adding Gd3+. Overall, a 40-fold enhancement of Gd-HMME RTP intensity was achieved by adding both imidazole and Gd3+. In addition, there was an increase in the RTP lifetime. Through spectroscopic analysis, we deduced that a protective medium is formed by the imidazole and the degree of this protection is further increased by Gd3+. The protective medium enhances the Gd-HMME RTP by partially inhibiting energy transfer from the lowest triplet state of Gd-HMME to oxygen. This was demonstrated by the presence of lower levels of singlet oxygen in the Gd-HMME solution after the addition of imidazole. These results indicate that imidazole could have potential application as an RTP enhancer or triplet state protector.

AB - The extraction of Pd(ii) and Rh(iii) from acidic solutions containing between 1 and 8 M HCl towards three ionic liquids, namely [P66614][Cl], [P66614][Br] and [P66614][DCA], based on the trihexyltetradecylphosphonium cation ([P66614]) and chloride, bromide or dicyanamide (DCA) anions, respectively, is reported. Extraction of Pd(ii) is quantitative up to 6 M HCl (D > 3000). A value of 258 for the distribution coefficient of Rh(iii) extracted from 1 M HCl towards [P66614][Br] is also reported. [P66614][Cl] and [P66614][Br] were found to be very efficient at separating these two metals from aqueous solutions containing at least 6 mol L-1 HCl.

AB - C, N co-modified niobium pentoxide (Nb2O5) nanoneedles have been successfully synthesized via a facile hydrothermal method with Niobium Chloride (NbCl5) as a precursor and triethylamine as both the carbon and nitrogen source. The formation process of Nb2O5 nanoneedles has been presented in detail by investigating the effect of the crystallization temperature, the amount of triethylamine and the calcination temperature. The as-prepared Nb2O5 nanoneedles exhibit more efficient photocatalytic activity than commercial Degussa P25 and commercial Nb2O5 towards photodegradation of Rhodamine B (RhB) at a concentration of 10 mg L-1 under visible light. Special chemical species, such as carbonate species and NOX species, that exist on the surface of the as-prepared catalyst could extend the absorption into the visible region and thus enhance the photocatalytic activity of the Nb2O5 nanoneedles. At the same time, the obtained Nb2O5 nanoneedles exhibit excellent stability even after three successive cycles. A possible photodegradation mechanism was proposed and the corresponding photodecomposition process of RhB over the Nb2O5 nanoneedles was elucidated by a reactive species trapping experiment, suggesting that h+ and O2- play a major role in the photodegradation of RhB in aqueous solution.

AB - A new type of polyoxometalate material, K6SiW11O39Ni(H2O).xH2O (denoted as SiW11Ni), was successfully synthesized and introduced to a dye-sensitized solar cell (DSSC) with modified traditional Pt as a novel composite counter electrode. The new counter electrode showed superior electrochemical catalytic activity for the reduction of I3- to I- in analysis utilizing a Tafel-polarization curve, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The DSSC assembled with the SiW11Ni/Pt photocathode exhibited an enhanced performance (7.03%) under the standard AM 1.5G illumination compared to the DSSC with a pristine Pt photocathode (6.65%). Furthermore, the DSSC based on the SiW11Ni/Pt photocathode had an increased light-harvesting efficiency and was very stable. The results demonstrate that SiW11Ni/Pt is an alternative and highly efficient counter electrode for dye-sensitized solar cells. Moreover, the facile design strategy is promising for fabricating efficient and inexpensive composite counter electrode catalysts for DSSCs. PMID- 27711787 TI - Effects of a nanoceria fuel additive on the physicochemical properties of diesel exhaust particles. AB - Nanoceria (i.e., CeO2 nanoparticles) fuel additives have been used in Europe and elsewhere to improve fuel efficiency. Previously we have shown that the use of a commercial fuel additive EnviroxTM in a diesel-powered electricity generator reduced emissions of diesel exhaust particle (DEP) mass and other pollutants. However, such additives are currently not permitted for use in on-road vehicles in North America, largely due to limited data on the potential health impact. In this study, we characterized a variety of physicochemical properties of DEPs emitted from the same engine. Our methods include novel techniques such as Raman spectrometry for analyzing particle surface structure and an assay for DEP oxidative potential. Results show that with increasing EnviroxTM concentrations in the fuel (0*, 0.1*, 1*, and 10* of manufacturer recommended 0.5 mL EnviroxTM per liter fuel), DEP sizes decreased from 194.6 +/- 20.1 to 116.3 +/- 14.8 nm; the zeta potential changed from -28.4 mV to -22.65 mV; DEP carbon content decreased from 91.8% to 79.4%; cerium and nitrogen contents increased from 0.3% to 6.5% and 0.2% to 0.6%, respectively; the ratio of organic carbon (OC) to elemental carbon (EC) increased from 22.9% to 38.7%; and the ratio of the disordered carbon structure to the ordered carbon structure (graphitized carbon) in DEPs decreased. Compared to DEPs emitted from 0*, 0.1*, and 1* fuels, DEPs from the 10* fuel had a lower oxidative potential likely due to the increased ceria content because pure ceria nanoparticles exhibited the lowest oxidative potential compared to all the DEPs. Since the physicochemical parameters tested here are among the determinants of particle toxicity, our findings imply that adding ceria nanoparticles into diesel may alter the toxicity of DEPs. The findings from the present study, hence, can help future studies that will examine the impact of nanoceria additives on DEP toxicities.

AB - The uranium metallacyclopropene (eta5-C5Me5)2U[eta2-C2(SiMe3)2] (1) reacts with various small unsaturated organic molecules. For example, replacement of bis(trimethylsilyl)acetylene occurs when complex 1 is exposed to alkynes, conjugated alkenes, nitriles and quinones. Reaction of 1 with internal phenyl(alkyl)acetylene PhC[triple bond, length as m-dash]CMe selectively yields the Cs symmetric uranium metallacyclopentadiene (eta5-C5Me5)2U[eta2-C(Ph)[double bond, length as m-dash]C(Me)-C(Ph)[double bond, length as m-dash]C(Me)] (6) after the loss of bis(trimethylsilyl)acetylene, while treatment of 1 with phenyl(silyl)acetylenes (PhC[triple bond, length as m-dash]CR, R = SiHMe2, SiMe3) gives the corresponding C2v symmetric isomers (eta5-C5Me5)2U[eta2-C(R)[double bond, length as m-dash]C(Ph)-C(Ph)[double bond, length as m-dash]C(R)] (R = SiHMe2 (7), SiMe3 (8)). Furthermore, while no deprotonation occurs between complex 1 and pyridine derivatives, cyclohexanone can be inserted into the uranium metallacyclopropene moiety of 1 to yield the five-membered, heterocyclic complex (eta5-C5Me5)2U[OC(CH2)5(C2(SiMe3)2)] (14) in quantitative conversion. Density functional theory (DFT) studies have been performed to complement the experimental studies. PMID- 27711791 TI - Towards controlling the dissociation probability by light-induced conical intersections. AB - Light-induced conical intersections (LICIs) can be formed both by standing or by running laser waves. The position of a LICI is determined by the laser frequency while the laser intensity controls the strength of the nonadiabatic coupling. Recently, it was shown within the LICI framework that linearly chirped laser pulses have an impact on the dissociation dynamics of the D2+ molecule (J. Chem. Phys., 143, 014305, (2015); J. Chem. Phys., 144, 074309, (2016)). In this work we exploit this finding and perform calculations using chirped laser pulses in which the time dependence of the laser frequency is designed so as to force the LICI to move together with the field-free vibrational wave packet as much as possible. Since nonadiabaticity is strongest in the vicinity of the conical intersection, this is the first step towards controlling the dissociation process via the LICI. Our showcase example is again the D2+ molecular ion. To demonstrate the impact of the LICIs on the dynamical properties of diatomics, the total dissociation probabilities and the population of the different vibrational levels after the dissociation process are studied and discussed.

AB - Triple molybdate NaCaLa(1-x-y)(MoO4)3:xEr3+,yYb3+ (x = y = 0, x = 0.05 and y = 0.45, x = 0.1 and y = 0.2, x = 0.2 and y = 0) phosphors were successfully synthesized for the first time by the microwave sol-gel method. Well-crystallized particles formed after heat treatment at 900 degrees C for 16 h showed a fine and homogeneous morphology with particle sizes of 2-3 MUm. The structures were refined by the Rietveld method in the space group I41/a. The optical properties were examined comparatively using photoluminescence emission and Raman spectroscopy. Under excitation at 980 nm, the NaCaLa0.7(MoO4)3:0.1Er3+,0.2Yb3+ and NaCaLa0.5(MoO4)3:0.05Er3+,0.45Yb3+ particles exhibited a strong 525 nm emission band, a weaker 550 nm emission band in the green region, and three weak 655 nm, 490 nm and 410 nm emission bands in the red, blue and violet regions. The pump power dependence and Commission Internationale de L'Eclairage chromaticity of the upconversion emission intensity were evaluated in detail.

AB - In this work, flexible 3D Co3O4@MnO2 heterostructures have been successfully obtained without using any surfactants. The as-prepared flexible electrodes exhibit high efficiency, high discharge areal capacitance (1397.2 mF cm-2 at 1 mA cm-2), long cycle life (13.9% loss after 6000 repetitive cycles at 1 mA cm-2) and excellent electrical stability. In addition, hybrid 3D Co3O4@MnO2 structures are also used as photocatalysts for the photocatalytic degradation of several harmful organic dyes under visible light illumination. The results show that the as-grown products possess excellent photocatalytic performance, demonstrating their potential applications in wastewater treatment.

AB - Two types of zinc flavonolato complexes ([(6-Ph2TPA)Zn(flavonolato)]ClO4 and Zn(flavonolato)2) of four extended flavonols have been prepared, characterized, and evaluated for visible light-induced CO release reactivity. Zinc coordination of each flavonolato anion results in a red-shift of the lowest energy absorption feature and in some cases enhanced molar absorptivity relative to the free flavonol. The zinc-coordinated flavonolato ligands undergo visible light-induced CO release with enhanced reaction quantum yields relative to the neutral flavonols. Most notable is the discovery that both types of zinc flavonolato derivatives undergo similar visible light-induced CO release reactivity in solution and in the solid state. A solid film of a Zn(flavonolato)2 derivative was evaluated as an in situ CO release agent for aerobic oxidative palladium catalyzed alkoxycarbonylation to produce esters in ethanol. The CO release product was found to undergo ester alcolysis under the conditions of the carbonylation reaction.

AB - The photodegradation rate of the herbicide imazethapyr on epicuticular waxes of soybean and corn plants was investigated. Plant age, relative humidity, temperature, and number of light banks were varied during plant growth, analyzed statistically, and examined to determine if these factors had an effect on the photodegradation of imazethapyr. Through ultraviolet/visible (UV-Vis) and fluorescence spectroscopy, epicuticular wax characteristics of soybean and corn plants were explored, were used to confirm observations determined statistically, and explain correlations between the rate constants and the composition of the epicuticular waxes. Plant age, the interaction between plant age and light, and the quadratic dependence on temperature were all determined to have a significant impact on the photodegradation rate of imazethapyr on the epicuticular waxes of soybean plants. As for the photodegradation rate on the epicuticular waxes of corn plants, the number of light banks used during growing and temperature were significant factors. PMID- 27711796 TI - Unimolecular dissociation of peptides: statistical vs. non-statistical fragmentation mechanisms and time scales. AB - In the present work we have investigated mechanisms of gas phase unimolecular dissociation of a relatively simple dipeptide, the di-proline anion, by means of chemical dynamics simulations, using the PM3 semi-empirical Hamiltonian. In particular, we have considered two activation processes that are representative limits of what occurs in collision induced dissociation experiments: (i) thermal activation, corresponding to several low energy collisions, in which the system is prepared with a microcanonical distribution of energy; (ii) collisional activation where a single shock of hundreds of kcal mol-1 (300 kcal mol-1 in the present case) can transfer sufficient energy to allow dissociation. From these two activation processes we obtained different product abundances, and for one particular fragmentation pathway a clear mechanistic difference for the two activation processes. This mechanism corresponds to the leaving of an OH- group and subsequent formation of water by taking a proton from the remaining molecule. This last reaction is always observed in thermal activation while in collisional activation it is less favoured and the formation of OH- as a final product is observed. More importantly, we show that while in thermal activation unimolecular dissociation follows exponential decay, in collision activation the initial population decays with non-exponential behaviour. Finally, from the thermal activation simulations it was possible to obtain rate constants as a function of temperature that show Arrhenius behaviour. Thus activation energies have also been extracted from these simulations.

PMID- 27711798 TI - Towards elucidating the photochemistry of the sunscreen filter ethyl ferulate using time-resolved gas-phase spectroscopy. AB - Ultrafast time-resolved ion yield (TR-IY) and velocity map imaging spectroscopies are employed to reveal the relaxation dynamics after photoexcitation in ethyl 4 hydroxy-3-methoxycinnamate (ethyl ferulate, EF), an active ingredient in commercially available sunscreens. In keeping with a bottom-up strategy, the building blocks of EF, 2-methoxy-4-vinylphenol (MVP) and 4-hydroxy-3 methoxycinnamyl alcohol (coniferyl alcohol, ConA), were also studied to assist in our understanding of the dynamics of EF as we build up in molecular complexity. In contrast to the excited state dynamics of MVP and ConA, which are described by a single time constant (>900 ps), the dynamics of EF are described by three time constants (15 +/- 4 ps, 148 +/- 47 ps, and >900 ps). A mechanism is proposed involving internal conversion (IC) between the initially excited S1(11pipi*) and S2(11npi*) states followed by intramolecular vibrational redistribution (IVR) on both states, in competition with intersystem crossing onto neighbouring triplet states (15 +/- 4 ps). IVR and IC within the triplet manifold then ensues (148 +/- 47 ps) to populate a low-lying triplet state (>900 ps). Importantly, the fluorescence spectrum of EF at the S1 origin, along with the associated lifetime (6.9 +/- 0.1 ns), suggests that population is trapped, during initial IVR, on the S1(11pipi*) state. This serves to demonstrate the complex, competing dynamics in this sunscreen filter molecule. PMID- 27711799 TI - Bilayer structured supramolecular light harvesting arrays based on zinc porphyrin coordination polymers for enhanced photocurrent generation in dye sensitized solar cells. AB - An acylhydrazone zinc porphyrin P1 and its coordination polymers (CPs, denoted as P1M, M = Mn, Co, Ni, Cu, Zn) with different metal ions (Mn2+, Co2+, Ni2+, Cu2+ and Zn2+) were synthesized. Then these coordination polymers were assembled into bilayer structured supramolecular chromophores through axially coordinating with anchoring porphyrin AP, and their performance in dye sensitized solar cells was investigated. Our results reveal that the bilayer structured supramolecular chromophore based solar cells show significantly improved photocurrent conversion efficiency. Particularly, P1Mn and P1Zn based solar cells showed a relatively higher short circuit current density (JSC) due to their broad absorption bands and remarkable light harvesting abilities. Meanwhile, the VOC values of the cells fabricated with the bilayered chromophores slightly decreased. Electrochemical impedance spectroscopy (EIS) in combination with charge extraction (CE) and transient photovoltage decay (TPD) measurements indicates that the decreased VOC resulted from the vigorous electron recombination and the downward shifted conduction band edge (ECB) of titania.

AB - Paradoxically, N- and O-donor substituted tri-arylphosphanes are shown to be weaker donors than PPh3 when binding the soft Lewis acid moiety [PPh2]+. This arises from internal solvation and rehybridisation at phosphorus, precluding chelation and increasing steric demand, in direct contrast to coordination modes observed for metal complexes. PMID- 27711801 TI - Plasmon resonance energy transfer and hot electron injection induced high photocurrent density in liquid junction Ag@Ag2S sensitized solar cells. AB - An in situ technique was developed to deposit Ag@Ag2S core-shell quantum dots on a SnO2 mesoporous film for solar energy conversion. When adopted as a photoanode, an impressive high photocurrent density of ~25.6 mA cm-2 was demonstrated in a cell configuration using polysulfide S2-/Sn2- as an electrolyte and Cu2S/brass as a counter electrode, which leads to a power conversion efficiency of ~0.784% for this environmentally benign device. Optical measurements showed that Ag nanoparticles could be employed as plasmon resonance centers to enhance the harvesting efficiency of incident light at the visible and near-infrared range. Moreover, photoluminescence spectra demonstrated fast charge transfer at Ag@Ag2S/SnO2 interfaces, which facilitates direct hot electron injection from sensitizers to the SnO2 matrix and finally gives rise to the high photocurrent density. PMID- 27711802 TI - An organo-functionalized metal-oxide cluster, [VO6{(OCH2CH2)2N(CH2CH2OH)}6], with Anderson-like structure. AB - A new polyoxovanadium cluster compound, [VO6{(OCH2CH2)2N(CH2CH2OH)}6].0.5CH3CN, was synthesized and characterized by single-crystal X-ray diffraction analysis, FTIR and UV-vis spectroscopy, and TGA. The cluster is composed of a fully reduced cyclic {V6N6O18} framework, which adopts an Anderson-like structure and is comprised of a ring of six edge-sharing {VO5N} octahedra incorporating six {(OCH2CH2)2N(CH2CH2OH)} ligands. Two (OCH2CH2-) arms of each of the six triethanolamine ligands are directly incorporated into the oxometalate core and the third {-CH2CH2OH} arm remains pendant. In the condensed phase, the clusters form discrete hcp layers through inter-cluster hydrogen bonding. These layers stack through soft chemical interactions to form a 3D network structure. The neutral cluster, [VO6{(OCH2CH2)2N(CH2CH2OH)}6], is the isopolyoxovanadium analogue to the cationic clusters contained in a series of heteropolyoxovanadium compounds previously introduced by our laboratory, e.g., [LiVO6{(OCH2CH2)2N(CH2CH2OH)}6]+; its existence shows that a heteroatom is not required to form or stabilize the common organofunctionalized vanadium oxide framework: [VO6{(OCH2CH2)2N(CH2CH2OH)}6]. To the best of our knowledge, the isopolyoxovanadium and heteropolyoxovanadium clusters represent the first reported isopoly-heteropoly analogues in the polyoxometalate field. We compare the TGA profile, FTIR and UV-vis spectra of the new compound with two of its cationic heteropoly analogues.

AB - The behavior of a series of Manganese (Mn) carbonyl compounds with 2,2':6',2'' terpyridine (tpy) in kappa2-N,N' and kappa3-N,N',N'' coordination modes under electrochemically reducing conditions is reported. In the presence of carbon dioxide (CO2) and Bronsted acid (phenol), two-electron reduction to carbon monoxide (CO) and water (H2O) is observed. Based on data obtained from cyclic voltammetry and infrared spectroelectrochemistry, the active state of the catalyst in the proposed mechanism for all cases is [Mn(kappa3-N,N',N'' tpy)(CO)2]-. Under these conditions, competing decomposition reactions limit the overall Faradaic efficiency. These results suggest the possibility of developing new tridentate ligand frameworks suitable for catalytic systems with Mn carbonyl cores. PMID- 27711805 TI - The structure of a one-electron oxidized Mn(iii)-bis(phenolate)dipyrrin radical complex and oxidation catalysis control via ligand-centered redox activity. AB - The tetradentate ligand dppH3, which features a half-porphyrin and two electron rich phenol moieties, was prepared and chelated to manganese. The mononuclear Mn(iii)-dipyrrophenolate complex 1 was structurally characterized. The metal ion lies in a square pyramidal environment, the apical position being occupied by a methanol molecule. Complex 1 displays two reversible oxidation waves at 0.00 V and 0.47 V vs. Fc+/Fc, which are assigned to ligand-centered processes. The one electron oxidized species 1+ SbF6- was crystallized, showing an octahedral Mn(iii) center with two water molecules coordinated at both apical positions. The bond distance analysis and DFT calculations disclose that the radical is delocalized over the whole aromatic framework. Complex 1+ SbF6- exhibits an Stot = 3/2 spin state due to the antiferromagnetic coupling between Mn(iii) and the ligand radical. The zero field splitting parameters are D = 1.6 cm-1, E/D = 0.18(1), g? = 1.99 and g? = 1.98. The dication 12+ is an integer spin system, which is assigned to a doubly oxidized ligand coordinated to a Mn(iii) metal center. Both 1 and 1+ SbF6- catalyze styrene oxidation in the presence of PhIO, but the nature of the main reaction product is different. Styrene oxide is the main reaction product when using 1, but phenylacetaldehyde is formed predominantly when using 1+ SbF6-. We examined the ability of complex 1+ SbF6- to catalyze the isomerization of styrene oxide and found that it is an efficient catalyst for the anti-Markovnikov opening of styrene oxide. The formation of phenylacetaldehyde from styrene therefore proceeds in a tandem E-I (epoxidation isomerization) mechanism in the case of 1+ SbF6-. This is the first evidence of control of the reactivity for styrene oxidation by changing the oxidation state of a catalyst based on a redox-active ligand.

AB - The ultra-bright femtosecond X-ray pulses provided by X-ray Free Electron Lasers (XFELs) open capabilities for studying the structure and dynamics of a wide variety of biological and inorganic systems beyond what is possible at synchrotron sources. Although the structure and chemistry at the catalytic sites have been studied intensively in both biological and inorganic systems, a full understanding of the atomic-scale chemistry requires new approaches beyond the steady state X-ray crystallography and X-ray spectroscopy at cryogenic temperatures. Following the dynamic changes in the geometric and electronic structure at ambient conditions, while overcoming X-ray damage to the redox active catalytic center, is key for deriving reaction mechanisms. Such studies become possible by using the intense and ultra-short femtosecond X-ray pulses from an XFEL, where sample is probed before it is damaged. We have developed methodology for simultaneously collecting X-ray diffraction data and X-ray emission spectra, using an energy dispersive spectrometer, at ambient conditions, and used this approach to study the room temperature structure and intermediate states of the photosynthetic water oxidizing metallo-protein, photosystem II. Moreover, we have also used this setup to simultaneously collect the X-ray emission spectra from multiple metals to follow the ultrafast dynamics of light induced charge transfer between multiple metal sites. A Mn-Ti containing system was studied at an XFEL to demonstrate the efficacy and potential of this method. PMID- 27711806 TI - Synthesis and reactivity of N,N'-1,4-diazabutadiene derived borocations.

AB - We present an account of our recent effort to improve simulation of the photodissociation of small heteroaromatic molecules using the Ab Initio Multiple Cloning (AIMC) algorithm. The ultimate goal is to create a quantitative and converged technique for fully quantum simulations which treats both electrons and nuclei on a fully quantum level. We calculate and analyse the total kinetic energy release (TKER) spectra and Velocity Map Images (VMI), and compare the results directly with experimental measurements. In this work, we perform new extensive calculations using an improved AIMC algorithm that now takes into account the tunnelling of hydrogen atoms. This can play an extremely important role in photodissociation dynamics. PMID- 27711809 TI - In situ video-STM studies of the mechanisms and dynamics of electrochemical bismuth nanostructure formation on Au. AB - The microscopic mechanisms of Bi electrodeposition on Au(111) and Au(100) electrodes in the overpotential regime were studied by in situ scanning tunneling microscopy with high spatial and temporal resolution. Atomic resolution images of the needle-like Bi(110) deposits formed on Au(111) reveal the central influence of covalent Bi-Bi bonds on the deposit morphology. In the straight steps along the needle edges the Bi atoms are interlinked by these bonds, whereas at the needle tip and at kinks along the needle edges dangling bonds exist, explaining the rapid structural fluctuations at these sites. For ultrathin Bi deposits on Au(100) a more open atomic arrangement was found within the surface plane, which was tentatively assigned to an epitaxially stabilised Bi(111) film. Furthermore, well-defined nanowires, consisting of zigzag chains of Bi surface atoms, were observed on this surface. PMID- 27711810 TI - Activation of aldehydes by exocyclic iridium(i)-eta4:pi2-diene complexes derived from 1,3-oxazolidin-2-ones. AB - The Ir(i) complexes [TpMe2Ir(eta4-1,4-diene)] 2b and 2c react thermally with a variety of aromatic aldehydes, 3a-e, to generate the metallabicyclic compounds 4e k and the Fischer-type carbenes 5a-b in moderate yields. These reactions are proposed to take place with the initial formation of eta1-aldehyde adducts as key intermediates. The formation of the metallabicyclic compounds 4e-k involves a formal decarboxylation process at the exo-2-oxazolidinone diene and an ortho metallation of the aromatic ring. The generation of the Fischer-type carbenes 5a b is the result of a series of metal-based rearranged intermediates with no decarboxylation observed. Treatment of the eta4-diene complex 2b with a variety of Lewis bases induces a change in the binding mode of the diene ligand from eta4:pi2 to eta2:sigma2 to form the Ir(iii) derivatives 6b-d of composition TpMe2Ir-(eta4:pi2-1,4-diene)(L) (L = CO, MeCN, and C5H5N). A study of reactions of complex 2b with either mono- or poly-deuterated aldehydes was performed to understand the mechanisms of such processes. The results of these studies were used to determine plausible formation mechanisms of the metallabicyclic compounds 4e-4k and Fischer-type carbenes 5a-b compound series. These mechanisms were corroborated by density functional theory (DFT) calculations of the free energy profiles. PMID- 27711811 TI - S-shooting: a Bennett-Chandler-like method for the computation of rate constants from committor trajectories. AB - Mechanisms of rare transitions between long-lived stable states are often analyzed in terms of commitment probabilities, determined from swarms of short molecular dynamics trajectories. Here, we present a computer simulation method to determine rate constants from such short trajectories combined with free energy calculations. The method, akin to the Bennett-Chandler approach for the calculation of reaction rate constants, requires the definition of a valid reaction coordinate and can be applied to both under- and overdamped dynamics. We verify the correctness of the algorithm using a one-dimensional random walker in a double-well potential and demonstrate its applicability to complex transitions in condensed systems by calculating cavitation rates for water at negative pressures. PMID- 27711812 TI - Decoherence, control and attosecond probing of XUV-induced charge migration in biomolecules. A theoretical outlook. AB - The sudden ionization of a molecule by an attosecond pulse is followed by charge redistribution on a time scale from a few femtoseconds down to hundreds of attoseconds. This ultrafast redistribution is the result of the coherent superposition of electronic continua associated with the ionization thresholds that are reached by the broadband attosecond pulse. Thus, a correct theoretical description of the time evolution of the ensuing wave packet requires the knowledge of the actual ionization amplitudes associated with all open ionization channels, a real challenge for large and medium-size molecules. Recently, the first calculation of this kind has come to light, allowing for interpretation of ultrafast electron dynamics observed in attosecond pump-probe experiments performed on the amino acid phenylalanine [Calegari et al., Science 2014, 346, 336]. However, as in most previous theoretical works, the interpretation was based on various simplifying assumptions, namely, the ionized electron was not included in the description of the cation dynamics, the nuclei were fixed at their initial position during the hole migration process, and the effect of the IR probe pulse was ignored. Here we go a step further and discuss the consequences of including these effects in the photoionization of the glycine molecule. We show that (i) the ionized electron does not affect hole dynamics beyond the first femtosecond, and (ii) nuclear dynamics has only a significant effect after approximately 8 fs, but does not destroy the coherent motion of the electronic wave packet during at least few additional tens of fs. As a first step towards understanding the role of the probe pulse, we have considered an XUV probe pulse, instead of a strong IR one, and show that such an XUV probe does not introduce significant distortions in the pump-induced dynamics, suggesting that pump-probe strategies are suitable for imaging and manipulating charge migration in complex molecules. Furthermore, we show that hole dynamics can be changed by shaping the attosecond pump pulse, thus opening the door to the control of charge dynamics in biomolecules. PMID- 27711814 TI - Theory of electrostatic phenomena in water-filled Pt nanopores. AB - The emerging field of nanoprotonics is concerned with controlling proton distribution and transport in nanoporous media. These phenomena, dictated by the surface charging properties of the host medium, are of vital importance in porous electrodes for fuel cells, electrolysers, supercapacitors and nanofluidic devices. In this theoretical study, we explore the interplay of the metal charging relation with the proton density and oxygen reduction activity in a water-filled nanopore with walls made of platinum. We exploit a non-monotonic charging behavior derived from a refined structural model of the Pt-solution interface. This charging relation replaces the oversimplified linear relation that has been widely used in practical applications. The water-filled pore, with one opening interfacing with a polymer electrolyte membrane as a proton source, always possesses negative surface charge in the potential range of 0-1.0 V (RHE). Therefore, its proton conductivity can be several orders higher than that of pure water. We obtain an analytical expression for the oxygen reduction activity of the nanopore and parameterize it using the polarization data of an ionomer-free thin-film Pt electrode. The structure vs. performance relation of the water filled Pt nanopore is examined. PMID- 27711813 TI - Novel dinitromethyl-featured polynitro energetic salts. AB - A unique and facile method was developed to synthesize a new class of energetic salts based on 2-amino-1,1,5,5-tetranitro-4-oxo-3-aza-pentene. All the salts were fully characterized by NMR (1H and 13C), IR spectroscopy and elemental analysis. Furthermore, the crystal structure of the guanidinium salt (5) was determined by single-crystal X-ray diffraction. The differential scanning calorimetry (DSC) results showed that the decomposition temperatures of these salts were between 126.2 degrees C (10) and 148.8 degrees C (9). The densities of these salts lie in the range of 1.745 (8) to 1.880 (4) g cm-3. Their impact sensitivities and friction sensitivities were measured to be in the range of 1-16 J and 48-84 N, respectively. All the salts exhibited promising detonation performances (detonation pressure: 28.6 to 34.3 GPa; detonation velocity: 8037 to 8674 m s-1), and the detonation performances of salt 4 were comparable to those of RDX.

AB - The preparation of metal-free, Zn(ii), In(iii), and Cu(ii)-phthalocyanines containing tetrakis-(3-phenylphenoxy) groups was achieved by employing 3-(3 phenylphenoxy)phthalonitrile (1) and 4-(3-phenylphenoxy)phthalonitrile (2) as starting materials. The phthalonitriles and phthalocyanines were characterized by elemental analysis, infrared, proton nuclear magnetic resonance, ultraviolet visible, and matrix-assisted laser desorption/ionization time-of-flight mass spectroscopic techniques. The effect of the substituent group on the kinetics of benzene vapour adsorption onto these novel compounds was examined using three kinetics models: the pseudo first-order model, the Elovich equation, and a simple adsorption-desorption model. Results show that the benzene adsorption kinetics strongly depend on the position of the substituent groups. PMID- 27711816 TI - A theoretical consideration of ion size effects on the electric double layer and voltammetry of nanometer-sized disk electrodes. AB - Considering that an electric-double-layer (EDL) structure may significantly impact on the mass transport and charge transfer kinetics at the interfaces of nanometer-sized electrodes, while EDL structures could be altered by the finite sizes of electrolyte and redox ions, the possible effects of ion sizes on EDL structures and voltammetric responses of nanometer-sized disk (nanodisk) electrodes are investigated. Modified Boltzmann and Nernst-Planck (NP) equations, which include the influence of the finite ion volumes, are combined with the Poisson equation and modified Butler-Volmer equation to gain knowledge on how the finite sizes of ions and the nanometer sizes of electrodes may couple with each other to affect the structures and reactivities of a nanoscale electrochemical interface. Two typical ion radii, 0.38 nm and 0.68 nm, which could represent the sizes of the commonly used aqueous electrolyte ions (e.g., the solvated K+) and the organic electrolyte ions (e.g., the solvated TEA+) respectively, are considered. The finite size of ions can result in decreased screening of electrode charges, therefore magnifying EDL effects on the ion transport and the electron transfer at electrochemical interfaces. This finite size effect of ions becomes more pronounced for larger ions and at smaller electrodes as the electrode radii is larger than 10 nm. For electrodes with radii smaller than 10 nm, however, the ion size effect may be less pronounced with decreasing the electrode size. This can be explained in terms of the increased edge effect of disk electrodes at nanometer scales, which could relax the ion crowding at/near the outer Helmholtz plane. The conditions and situations under which the ion sizes may have a significant effect on the voltammetry of electrodes are discussed.

Ongoing developments in ultrafast extreme vacuum ultraviolet (XUV) and soft X-ray sources present new probes of coupled electronic-structural dynamics because of their novel and desirable characteristics. As one example, inner-shell spectroscopy offers localized, atom-specific probes of evolving electronic structure and bonding (via chemical shifts). In this work, we present the first on-the-fly ultrafast X-ray time-resolved absorption spectrum simulations of excited state wavepacket dynamics: photo-excited ethylene. This was achieved by coupling the ab initio multiple spawning (AIMS) method, employing on-the-fly dynamics simulations, with high-level algebraic diagrammatic construction (ADC) X-ray absorption cross section calculations. Using the excited state dynamics of ethylene as a test case, we assessed the ability of X-ray absorption spectroscopy to project out the electronic character of complex wavepacket dynamics, and evaluated the sensitivity of the calculated spectra to large amplitude nuclear motion. In particular, we demonstrate the pronounced sensitivity of the pre-edge region of the X-ray absorption spectrum to the electronic and structural evolution of the excited-state wavepacket. We conclude that ultrafast time-resolved X-ray absorption spectroscopy may become a powerful tool in the interrogation of excited state non-adiabatic molecular dynamics.

AB - An atomic scale model of the electrical double layer is used to calculate the mechanism and rate of electrochemical reduction of CO2 as well as H2 formation at a Pt(111) electrode. The water layer contains solvated protons and the electrode has excess electrons at the surface. Density functional theory within the generalized gradient approximation is used to describe the electronic structure while the mechanism and activation energy of the various elementary reactions is obtained by calculating minimum energy paths using the nudged elastic band method. The applied electrical potential is deduced from the calculated work function. The optimal reaction mechanism for CO2 reduction to either methane or methanol is found and the estimated rate compared with that of the competing reaction, H2 formation. When the free energy of only the intermediates and reactants is taken into account, not the activation energy, Pt(111) would seem to be a good electrocatalyst for CO2 reduction, significantly better than Cu(111). This, however, contradicts experimental findings. Detailed calculations reported here show that the activation energy for CO2 reduction is high for both Heyrovsky and Tafel mechanisms on Pt(111) in the relevant range of applied potential. The rate-limiting step of the Heyrovsky mechanism, *COOH + H+ + e- -> *CO + H2O, is estimated to have an activation energy of 0.95 eV at -0.9 V vs. standard hydrogen electrode. Under the same conditions, the activation energy for H2 formation is estimated to be only 0.5 eV. This explains why attempts to reduce CO2 using platinum electrodes have produced only H2. A comparison is made with analogous results for Cu(111) [J. Hussain et al., Procedia Comput. Sci., 2015, 51, 1865] where a reaction mechanism with low activation energy for CO2 electroreduction to methane was identified. The difference between the two electrocatalysts is discussed.

AB - The three new blue-fluorescent ligands 2,7-bis(tetramethylguanidino)-1,8 naphthyridine (1), 2,7-bis(N,N'-dimethylethylene-guanidino)-1,8-naphthyridine (2) and 2,7-bis(N,N'-diisopropylguanidino)-1,8-naphthyridine (3) are synthesized, and their optical properties (electronic absorption and emission spectroscopy) studied. Reactions of 1 or 2 with [Cu(CH3CN)4]BF4 yield the Cu4 chain compounds [Cu4(1)2](BF4)4 (that crystallizes as [Cu4(1)2(CH3CN)2](BF4)4.2CH2Cl2) and [Cu4(2)2](BF4)4. The variations of the optical properties upon coordination are evaluated, and the electronic transitions identified by time-dependent DFT (TD DFT) calculations. Then the redox properties of the new Cu4 chain complexes are studied. In the course of these experiments, the new Cu6 complex [Cu4(1)2(CuCl2)2]2+, in which two CuCl2- units coordinate to the Cu4 chain in [Cu4(1)2]4+, was fully characterized. In addition, the Cu3 chain complexes [Cu3(1)3]3+ and [Cu3(1)2]3+ were isolated as products of redox-induced degradation processes. Finally, we show by quantum chemical calculations that in [M4(1)2]4+ complexes (M = coinage metal), the HOMO changes from a ligand-centered to a metal-centered orbital for replacement of M = Cu by Au. PMID- 27711820 TI - Interactions of anions and cations in carbon nanotubes. AB - We consider the insertion of alkali-halide ion pairs into a narrow (5,5) carbon nanotube. In all cases considered, the insertion of a dimer is only slightly exothermic. While the image charge induced on the surface of the tube favors insertion, it simultaneously weakens the Coulomb attraction between the two ions. In addition, the anion experiences a sizable Pauli repulsion. For a one dimensional chain of NaCl embedded in the tube the most favorable position for the anion is at the center, and for the cation near the wall. The phonon spectrum of such chains shows both an acoustic and an optical branch. PMID- 27711821 TI - The antioxidant effect of mulberry and jamun fruit wines by ameliorating oxidative stress in streptozotocin-induced diabetic Wistar rats. AB - Polyphenols act by scavenging reactive oxygen species during oxidative stress and hence are useful in the treatment of metabolic disorders including diabetes. This study describes the effect of polyphenol rich mulberry and jamun wines fed to streptozotocin-induced diabetic rats. To male adult Wistar rats, divided into groups (n = 10 per group) intraperitoneal injection was administered with streptozotocin at 38 mg per kg body weight for inducing diabetes. After confirmation of diabetes, rats divided into groups were fed each day with 5.7 milliliter per kg body weight of mulberry, jamun, white and red grape wines for 6 weeks. One group of animals received resveratrol at 20 mg per kg body weight. After six weeks of treatment, blood glucose, urinary profile, lipid profile, plasma, liver, kidney, brain and eye antioxidant enzyme activities, lipid peroxidation, non-esterified fatty acids (NEFA) and hepatic glutathione (GSH) content were determined. Though wine and resveratrol feeding did not improve the glycemic status of diabetic rats, increases in antioxidant enzymes and GSH content accompanied by reduced NEFA and lipid peroxidation were observed. The kidneys and brains of resveratrol fed rats showed significant reduction in malondialdehyde equivalents, exhibited an improved antioxidant status of tissues and an increased glutathione content. The findings suggested that the wines can ameliorate the consequences of diabetes due to their antioxidants. PMID- 27711822 TI - Controllable fabrication of urchin-like Co3O4 hollow spheres for high-performance supercapacitors and lithium-ion batteries. AB - Urchin-like cobalt oxide (Co3O4) hollow spheres can be successfully prepared by thermal decomposition of cobalt carbonate hydroxide hydrate (Co(CO3)0.5(OH).0.11H2O) obtained by template-assisted hydrothermal synthesis. The morphology, crystal structure evolution and thermal decomposition behaviors of the as-prepared products have been carefully investigated. A plausible formation mechanism of the urchin-like Co3O4 hollow spheres in the presence of hexadecyl trimethyl ammonium bromide (CTAB) as the surfactant template is proposed. The urchin-like Co3O4 hollow spheres are further constructed as electrode materials for high-performance supercapacitors with a high specific capacitance of 460 F g-1 at a current density of 4 A g-1 and excellent cycling stability. Furthermore, as anode materials for lithium-ion batteries (LIBs), superior lithium storage performance of 1342.2 mA h g-1 (0.1 C) and 1122.7 mA h g 1 (0.2 C) can also be achieved. The excellent performances can be ascribed to the unique hierarchical urchin-like hollow structure of the electrode materials, which offers a large specific surface area, short electron and ion diffusion paths and high permeability while being directly in contact with the electrolyte. Moreover, the hollow structure with sufficient internal void spaces can self accommodate volume change during electrochemical reactions, which improves the structural stability and integrity.

AB - We report novel ion-pair bisphosphine CuI/CuIII trifluoromethyl complexes [(P2)2CuI]+[CuIII(CF3)4]- (P2 = DPPE, BINAP or Xantphos) featuring tetrahedral CuI and square planar CuIII units that are prepared via oxidative trifluoromethylation of CuI with CF3SiMe3 in the presence of AgF. The bisphosphine CuI/CuIII CF3 complexes are highly reactive for aerobic trifluoromethylation of arylboronic acids to produce trifluoromethylated arenes in good to quantitative yields, which is in sharp contrast to the CuI/CuIII complex with phen/PPh3 ligands (1'). These results not only provide strong evidence that both the neutral and ion-pair CuIII CF3 complexes are competent catalytic species for Cu-mediated oxidative trifluoromethylation reactions, but also have important mechanistic implications that the active catalyst and reaction mechanism should be distinct and ligand-dependent for trifluoromethylation reactions with different types of ancillary ligands.

AB - The covalent functionalization of metal oxide surfaces with organic ligands gives unique organic-inorganic hybrids. Here we report a bifunctional organic tether combining a phosphonate for metal oxide anchoring with an organic azide for attachment of organic groups. Stable binding of the tether to molecular and solid state metal oxides is demonstrated and the subsequent "CLICKability" of the TiO2 anchored tether is shown. The phosphonate-azide reported could in future allow the general linkage of functional organic groups to metal oxides. PMID- 27711824 TI - The effect of a plant extract enriched in stigmasterol and beta-sitosterol on glycaemic status and glucose metabolism in alloxan-induced diabetic rats. AB - Banana is an extensively cultivated plant worldwide, mainly for its fruit, while its ancillary product, the banana pseudostem, is consumed as a vegetable and is highly recommended for diabetics in the traditional Indian medicine system. The present study was aimed at elucidating the mechanism of antihyperglycaemia exerted by the ethanol extract of banana pseudostem (EE) and its isolated compounds viz., stigmasterol (C1) and beta-sitosterol (C2), in an alloxan-induced diabetic rat model. Diabetic rats which were administered with C1, C2 and EE (100 and 200 mg per kg b. wt.) for 4 weeks showed reduced levels of fasting blood glucose and reversal of abnormalities in serum/urine protein, urea and creatinine in diabetic rats compared to the diabetic control group of rats. Diabetic symptoms such as polyphagia, polydipsia, polyuria, urine glucose and reduced body weight were ameliorated in the diabetic group of rats fed with EE, C1 and C2 (100 mg per kg b. wt., once daily) for 28 days. The levels of insulin and Hb were also increased, while the HbA1c level was reduced. The altered activities of hepatic marker enzymes viz., aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP); glycolytic enzyme (hexokinase); shunt enzyme (glucose 6-phosphate dehydrogenase); gluconeogenic enzymes (glucose-6-phosphatase, fructose-1,6-bisphosphatase and lactate dehydrogenase) and pyruvate kinase were significantly reverted to normal levels by the administration of EE, C1 and C2. In addition, increased levels of hepatic glycogen and glycogen synthase and the corresponding decrease of glycogen phosphorylase activity in diabetic rats illustrated the antihyperglycaemic potential of EE and its components. The histological observations revealed a marked regeneration of the beta-cells in the drug treated diabetic rats. These findings suggest that EE might exert its antidiabetic potential in the presence of C1 and C2, attributable to the enhanced glycolytic activity, besides increasing the hepatic glucose utilization in diabetic rats by stimulating insulin secretion from the remnant beta-cells. PMID- 27711826 TI - Femtosecond gas phase electron diffraction with MeV electrons. AB - We present results on ultrafast gas electron diffraction (UGED) experiments with femtosecond resolution using the MeV electron gun at SLAC National Accelerator Laboratory. UGED is a promising method to investigate molecular dynamics in the gas phase because electron pulses can probe the structure with a high spatial resolution. Until recently, however, it was not possible for UGED to reach the relevant timescale for the motion of the nuclei during a molecular reaction. Using MeV electron pulses has allowed us to overcome the main challenges in reaching femtosecond resolution, namely delivering short electron pulses on a gas target, overcoming the effect of velocity mismatch between pump laser pulses and the probe electron pulses, and maintaining a low timing jitter. At electron kinetic energies above 3 MeV, the velocity mismatch between laser and electron pulses becomes negligible. The relativistic electrons are also less susceptible to temporal broadening due to the Coulomb force. One of the challenges of diffraction with relativistic electrons is that the small de Broglie wavelength results in very small diffraction angles. In this paper we describe the new setup and its characterization, including capturing static diffraction patterns of molecules in the gas phase, finding time-zero with sub-picosecond accuracy and first time-resolved diffraction experiments. The new device can achieve a temporal resolution of 100 fs root-mean-square, and sub-angstrom spatial resolution. The collimation of the beam is sufficient to measure the diffraction pattern, and the transverse coherence is on the order of 2 nm. Currently, the temporal resolution is limited both by the pulse duration of the electron pulse on target and by the timing jitter, while the spatial resolution is limited by the average electron beam current and the signal-to-noise ratio of the detection system. We also discuss plans for improving both the temporal resolution and the spatial resolution. PMID- 27711827 TI - 1/f 2 noise in bistable electrocatalytic reactions on mesoscale electrodes. AB - The formation of a self-organized spatial domain during current-controlled CO oxidation, a kinetically bistable reaction, is investigated experimentally and by deterministic simulations as a function of the electrode size and of the supporting electrolyte concentration. Decreasing the microelectrode size leads to the suppression of the spatial instability at the electrode and thus stabilizes the S-NDR branch of the reaction. The critical microelectrode size capable of supporting sustained domain formation is shown to be strongly affected by the sulfuric acid concentration, the characteristic time of the positive feedback loop increasing with the sulfate concentration. Furthermore, we demonstrate that for microelectrode diameters close to the instability threshold, small amplitude electrochemical potential fluctuations appear in the system. These potential fluctuations cannot be captured by deterministic mathematical models and are attributed to a strong enhancement of molecular fluctuations or intrinsic noise in the vicinity of the spatial instability. Analysis of the electrochemical noise revealed a 1/f 2 frequency dependence and several common features with neuronal shot noise. PMID- 27711828 TI - A comparison of MOP-phosphonite ligands and their applications in Rh(i)- and Pd(ii)-catalysed asymmetric transformations. AB - Six chiral MOP-phosphonites have been synthesised and compared via experimental and computational methods in an effort to quantify their differing structural and electronic profiles. They were found to be electron-poor ligands in comparison to their arylphosphine analogues and have a larger trans influence in square planar Pt(ii) complexes. Four [Rh(LP)(eta2:eta2-cod)Cl] complexes were synthesised and characterised by NMR, HRMS and X-ray crystallography. Two [Rh(LP)2]BF4 complexes were prepared where one ligand acts as a chelating P,C-pi-donor; detailed NMR studies demonstrated a hemilabile eta6-coordination mode, which in one case was confirmed by X-ray crystallography. Rh(i) complexes were used as catalysts in asymmetric hydrogenation and hydroformylation reactions and in the addition of phenyl boronic acid to an isatin. Pd(ii) complexes were successfully employed in asymmetric Suzuki-Miyaura cross-coupling reactions yielding binaphthyl products. Two [Pd(LP)2Cl2] complexes were synthesised and characterised by X-ray crystallography, both adopting cis orientations, with one of the complexes crystallising as two pseudo-polymorphs. PMID- 27711829 TI - Probing spin-vibronic dynamics using femtosecond X-ray spectroscopy. AB - Ultrafast pump-probe spectroscopy within the X-ray regime is now possible owing to the development of X-ray Free Electrons Lasers (X-FELs) and is opening new opportunities for the direct probing of femtosecond evolution of the nuclei, the electronic and spin degrees of freedom. In this contribution we use wavepacket dynamics of the photoexcited decay of a new Fe(ii) complex, [Fe(bmip)2]2+ (bmip = 2,6-bis(3-methyl-imidazole-1-ylidine)pyridine), to simulate the experimental observables associated with femtosecond Fe K-edge X-ray Absorption Near-Edge Structure (XANES) and X-ray emission (XES) spectroscopy. We show how the evolution of the nuclear wavepacket is translated into the spectroscopic signal and the sensitivity of these approaches for following excited state dynamics. PMID- 27711830 TI - Role of tunnel ionization in high harmonic generation from substituted benzenes. AB - We theoretically study high-harmonic generation in toluene, ortho-xylene and fluorobenzene driven by a 1.8 MUm ultrashort pulse. We find that the chemical substitutions have a strong influence on the amplitude and phase of the emission from the highest occupied molecular orbital, despite having a small influence on the orbital itself. We show that this influence is due to the tunnel ionization step, which depends critically on the sign and amplitude of the asymptotic part of the wave function. We discuss how these effects would manifest in phase sensitive high-harmonic generation spectroscopy experiments. PMID- 27711831 TI - Four-wave-mixing experiments with seeded free electron lasers. AB - The development of free electron laser (FEL) sources has provided an unprecedented bridge between the scientific communities working with ultrafast lasers and extreme ultraviolet (XUV) and X-ray radiation. Indeed, in recent years an increasing number of FEL-based applications have exploited methods and concepts typical of advanced optical approaches. In this context, we recently used a seeded FEL to demonstrate a four-wave-mixing (FWM) process stimulated by coherent XUV radiation, namely the XUV transient grating (X-TG). We hereby report on X-TG measurements carried out on a sample of silicon nitride (Si3N4). The recorded data bears evidence for two distinct signal decay mechanisms: one occurring on a sub-ps timescale and one following slower dynamics extending throughout and beyond the probed timescale range (100 ps). The latter is compatible with a slower relaxation (time decay > ns), that may be interpreted as the signature of thermal diffusion modes. From the peak intensity of the X-TG signal we could estimate a value of the effective third-order susceptibility which is substantially larger than that found in SiO2, so far the only sample with available X-TG data. Furthermore, the intensity of the time-coincidence peak shows a linear dependence on the intensity of the three input beams, indicating that the measurements were performed in the weak field regime. However, the timescale of the ultrafast relaxation exhibits a dependence on the intensity of the XUV radiation. We interpreted the observed behaviour as the generation of a population grating of free-electrons and holes that, on the sub-ps timescale, relaxes to generate lattice excitations. The background free detection inherent to the X-TG approach allowed the determination of FEL-induced electron dynamics with a sensitivity largely exceeding that of transient reflectivity and transmissivity measurements, usually employed for this purpose. PMID- 27711832 TI - Transformation of chlorpyrifos and chlorpyrifos-methyl in prairie pothole pore waters. AB - Non-point source pesticide pollution is a concern for wetlands in the prairie pothole region (PPR). Recent studies have demonstrated that reduced sulfur species (e.g., bisulfide and polysulfides) in PPR wetland pore waters directly undergo reactions with chloroacetanilide and dinitroaniline compounds. In this paper, the abiotic transformation of two organophosphate compounds, chlorpyrifos and chlorpyrifos-methyl, was studied in PPR wetland pore waters. Chlorpyrifos methyl reacted significantly faster (up to 4 times) in pore water with reduced sulfur species relative to hydrolysis. No rate enhancement was observed in the transformation of chlorpyrifos in pore water with reduced sulfur species. The lack of reactivity was most likely caused by steric hindrance from the ethyl groups and partitioning to dissolved organic matter (DOM), thereby shielding chlorpyrifos from nucleophilic attack. Significant decreases in reaction rates were observed for chlorpyrifos in pore water with high concentrations of DOM. Rate enhancement due to other reactive species (e.g., organo-sulfur compounds) in pore water was minor for both compounds relative to the influence of bisulfide and DOM. PMID- 27711833 TI - Arsenic releasing characteristics during the compaction of muddy sediments. AB - Muddy sediments are abundant in pore water and capable of preserving a large amount of chemicals, such as arsenic. Muddy sediments would transform into aquicludes or aquitards during long-term compaction and burial. It remains unclear whether the release of arsenic from muddy sediments poses a potential contamination risk to groundwater in the adjacent aquifer. An indoor compaction simulation experiment was conducted, coupled with an investigation on vertical geochemical profiles of muddy sediments in one actual borehole. In this experiment, aqueous arsenic in released pore water ranged from 17.5 to 21.3 MUg L 1 and the accumulated content of the released arsenic was 17.576 MUg during the compaction. As(iii) was the main As species in released pore water and had good correlations with Fe2+ and Mn. The analysis of the solid phase showed a remarkable depletion of Fe-Mn oxide bound arsenic during the compaction. In the profiles of the actual borehole, the contents of Fe-Mn oxide bound arsenic also exhibited a gradual decreasing trend from shallow to deep. Based on both the indoor experiment and the field profile, it can be concluded that the reductive dissolution of Fe-Mn oxides took place in arsenic-rich muddy sediments and Fe-Mn oxide-bound arsenic transformed into soluble arsenic, then soluble arsenic was released into the adjacent aquifer along with the pore water in the long-term compaction and burial. PMID- 27711834 TI - Discrimination of chiral copper(ii) complexes upon binding of galactonoamidine ligands. AB - The coordination between N-p-methylbenzyl-d-galactonoamidine, a putative transition state analogue of the hydrolyis of glycosidic bonds, and symmetric and chiral binuclear copper(ii) complexes was characterized by spectroscopic titration, isothermal titration calorimetry, circular dichroism spectroscopy, and DFT calculations to elucidate the binding sites in the carbohydrate upon coordination to selected metal complexes. For the formation of metal complex glyconoamidine assemblies, contributions of the amidine site and of the hydroxyl group at C-2 in the glycon of the amidine are noted. The chiral complexes S- and R-Cu2bpdbo are discriminated by a third binding site in the carbohydrate that leads to higher stability of complexes derived from S-Cu2bpdbo (4-5 kcal mol-1) compared to those formed from R-Cu2bpdbo. PMID- 27711835 TI - Structure property relationships affecting the proton conductivity in imidazole loaded Al-MOFs. AB - The structures of the imidazole loaded derivatives of Al-MIL-53 [Al(OH)(1,4-BDC (CH3)x)] (x = 0, 1, 2) and CAU-11 ([Al(OH)(SDBA)]) (1,4-H2BDC = terephthalic acid; H2SDBA = 4,4'-sulfonyldibenzoic acid) were determined from powder X-ray diffraction data. Impedance spectroscopy measurements were carried out to evaluate their proton conductivities under anhydrous conditions at temperatures up to 110 degrees C. In Al-MIL-53-(CH3)x_HIm (x = 0, 1, 2) the formation of hydrogen bonds between the framework and the guest molecules results in a decrease in proton conductivity (x0 = 1.7 * 10-6, x1 = 1.9 * 10-8 and x2 = 1.7 * 10-9 S cm-1 at 110 degrees C and Eact = 0.42, 0.41 and 0.46 eV, for 0, 1 and 2 CH3-groups, respectively). The highest conductivity has been measured for CAU 11_HIm with 3.0 * 10-4 S cm-1 at 110 degrees C (Eact = 0.19 eV), where no host guest hydrogen bonding interactions are observed. PMID- 27711836 TI - Pressure-dependent rate constants for PAH growth: formation of indene and its conversion to naphthalene. AB - Unraveling the mechanisms for growth of polycyclic aromatic hydrocarbons (PAHs) requires accurate temperature- and pressure-dependent rate coefficients for a great variety of feasible pathways. Even the pathways for the formation of the simplest PAHs, indene and naphthalene, are fairly complex. These pathways provide important prototypes for modeling larger PAH growth. In this work we employ the ab initio RRKM theory-based master equation approach to predict the rate constants involved in the formation of indene and its conversion to naphthalene. The reactions eventually leading to indene involve C9Hx (x = 8-11) potential energy surfaces (PESs) and include C6H5 + C3H4 (allene and propyne), C6H6 + C3H3, benzyl + C2H2, C6H5 + C3H6, C6H6 + C3H5 and C6H5 + C3H5. These predictions allow us to make a number of valuable observations on the role of various mechanisms. For instance, we demonstrate that reactions which can significantly contribute to the formation of indene include phenyl + allene and H-assisted isomerization to indene of its major product, 3-phenylpropyne, benzyl + acetylene, and the reactions of the phenyl radical with propene and the allyl radical, both proceeding via the 3-phenylpropene intermediate. 3-Phenylpropene can be activated to a 1-phenylallyl radical, which in turn rapidly decomposes to indene. Next, indene can be converted to benzofulvene or naphthalene under typical combustion conditions, via its activation by H atom abstraction and methyl substitution on the five-membered ring followed by isomerization and decomposition of the resulting 1-methylindenyl radical, C10H9 -> C10H8 + H. Alternatively, the same region of the C10H9 PES can be accessed through the reaction of benzyl with propargyl, C7H7 + C3H3 -> C10H10 -> C10H9 + H, which therefore can also contribute to the formation of benzofulvene or naphthalene. Benzofulvene easily transforms to naphthalene by H-assisted isomerization. An analysis of the effect of pressure on the reaction outcome and relative product yields is given, and modified Arrhenius fits of the rate constants are reported for the majority of the considered reactions. Ultimately, the implementation of such expressions in detailed kinetic models will help quantify the role of these reactions for PAH growth in various environments. PMID- 27711838 TI - Low-temperature chemistry using the R-matrix method. AB - Techniques for producing cold and ultracold molecules are enabling the study of chemical reactions and scattering at the quantum scattering limit, with only a few partial waves contributing to the incident channel, leading to the observation and even full control of state-to-state collisions in this regime. A new R-matrix formalism is presented for tackling problems involving low- and ultra-low energy collisions. This general formalism is particularly appropriate for slow collisions occurring on potential energy surfaces with deep wells. The many resonance states make such systems hard to treat theoretically but offer the best prospects for novel physics: resonances are already being widely used to control diatomic systems and should provide the route to steering ultracold reactions. Our R-matrix-based formalism builds on the progress made in variational calculations of molecular spectra by using these methods to provide wavefunctions for the whole system at short internuclear distances, (a regime known as the inner region). These wavefunctions are used to construct collision energy-dependent R-matrices which can then be propagated to give cross sections at each collision energy. The method is formulated for ultracold collision systems with differing numbers of atoms. PMID- 27711837 TI - Cyanotoxin degradation activity and mlr gene expression profiles of a Sphingopyxis sp. isolated from Lake Champlain, Canada. AB - A bacterium capable of degrading five microcystin (MC) variants, microcystin-LR, YR, LY, LW and LF at an initial total concentration of 50 MUg l-1 in less than 16 hours was isolated from Missisquoi Bay, in the south of Quebec, Canada. Phylogenetic analysis of the 16S rRNA gene sequence identified the bacterium as Sphingopyxis sp., designated strain MB-E. It was shown that microcystin biodegradation activity was reduced at acidic and basic pH values. Even though no biodegradation occurred at pH values of 5.05 and 10.23, strain MB-E was able to degrade MCLR and MCYR at pH 9.12 and all five MCs variants tested at pH 6.1. Genomic sequencing revealed that strain MB-E contained the microcystin degrading gene cluster, including the mlrA, mlrB, mlrC and mlrD genes, and transcriptomic analysis demonstrated that all of these genes were induced during the degradation of MCLR alone or in the mixture of all five MCs. This novel transcriptomic analysis showed that the expression of the mlr gene cluster was similar for MCLR alone, or the mixture of MCs, and appeared to be related to the total concentration of substrate. The results suggested that the bacterium used the same pathway for the degradation of all MC variants. PMID- 27711839 TI - The half-sandwich 18- and 16-electron arene ruthenium iminophosphonamide complexes. AB - Novel half-sandwich 18e and 16e arene ruthenium iminophosphonamide complexes [(eta6-C6Me6)RuCl{(R'N)2PR2}] (3a-c) and [(eta6-C6Me6)Ru{(R'N)2PR2}]+(X-) (4a-c) (a, R = Ph, R' = p-Tol; b, R = Et, R' = p-Tol; c, R = Ph, R' = Me. X = BF4, PF6 or BArF4) were synthesized. The elongated Ru-Cl bond in the 18e complexes is shown to dissociate even in apolar solvents to form the corresponding 16e cations, which can be readily isolated as salts with non-coordinating anions. The coordinatively unsaturated 16e complexes are stable species due to efficient pi electron donation from the nitrogen atoms of the zwitterionic NPN-ligand. The ruthenium iminophosphonamides are moderately active in the ROMP polymerization of norbornene; the 16e complexes 4a,b yield high molecular weight polymers (Mn~ 300 * 103) with a narrow distribution Mw/Mn~ 1.6, while the 18e complexes 3a,b give polymers of lower molecular weight (Mn < 50 * 103) with a wider polydispersity index Mw/Mn~ 2.5. PMID- 27711840 TI - A simple approach to a new T8-POSS based MRI contrast agent. AB - A fast and simple route was developed to synthesize a new T8-silsesquioxane based contrast agent for potential application in Magnetic Resonance Imaging. For this purpose the novel C2-thiol-functionalized T8-silsesquioxane (3) was constructed as a carrier molecule as well as the DOTA based gadolinium(iii) complex (11) equipped with allyl terminated linkers was prepared. The linkage of the complexes to the T8-silsesquioxane was performed via an UV-light catalyzed thiol-ene click reaction within one hour which affords the desired product 13 in a yield of 80%. The successful transformation as well as the intactness of the cube was confirmed by spectroscopic methods and mass spectrometry. This new and simple approach offers a highly effective access to T8-silsesquioxanes functionalized with eight metal complexes. Longitudinal relaxivity measurements of compound 13 (9.5 +/- 0.9 mM-1 s-1) at 3 T in HEPES buffered cell culture medium (physiological conditions) show a significant enhancement of r1 per 1 mM gadolinium in comparison to the clinically applied contrast agent DotaremTM (3.4 mM-1 s-1). In relation to the former reported T8-silsesquioxane based contrast agent Gadoxane G (10.6 mM-1 s-1) a similar relaxivity is found. As the T8-core of polyhedral oligosilsesquioxanes (POSS) based contrast agents undergoes a hydrolysis process depending on the pH, long-term r1 measurements in different solutions (water, cell culture medium and HEPES buffered medium) as well as 1H, 1H/29Si HSQC and PGSE diffusion 1H NMR spectroscopic investigations on aqueous solutions were performed. In solutions featuring an approximately neutral pH (D2O, pD = 7.0; water and HEPES buffered medium, pH = 7.4-7.5) contrast agent 13 (t1/2 = 2.4 d, HEPES/medium) shows a slower decomposition of the T8-cage in comparison to the previously synthesized Gadoxane G (t1/2 = 15 +/- 3 h, HEPES/medium). However, under more basic conditions (medium, pH = 8.4-8.5) the decomposition process of 13 is considerably accelerated (t1/2 ~ 55-60 min), indicating a higher sensitivity of the T8-cage to pH shifts into the basic range similar to Gadoxane G.

AB - Here we investigate the mechanistic aspects of Pt nanoparticle (NP) aggregation in solutions typically used for detecting NP/electrode impacts by electrocatalytic amplification (ECA). We previously proposed a general mechanism for Pt colloid destabilization that involved the participation of both the hydrazine redox probe and the pH buffer species as coagulants. Herein the Pt NP coagulation and aggregation mechanisms were further investigated with microscopic kinetic NP concentration monitoring and zeta potential measurements using nanoparticle tracking analysis (NTA), as well as open circuit potential experiments with a citrate-treated polycrystalline Pt surface to assess electrical double layer potential. After considering the combined results of these experiments we propose that the colloidal stability of citrate-capped platinum nanoparticles involves much more than the typical physicochemical interactions predicted by DLVO theory. A structure based on intermolecular H bonding in the citrate capping layer is the most plausible explanation for the exceptional stability of large Pt NPs in high ionic strength buffers. Thus, the mechanism of Pt NP aggregation includes specific reactive contributions from hydrazine. The catalytic decomposition of hydrazine, in particular, is thought to occur to some extent at the citrate-coated Pt surface while the citrate remains adsorbed. Evolved gases such as ammonia and possible surface bound intermediates from Pt-catalyzed decomposition of hydrazine may disrupt the stability of the citrate layer, causing colloidal instability and thus promoting Pt NP coagulation. In the closing section, we demonstrate nanoparticle impact electroanalysis by ECA detection as a method to quantify Pt NP concentration with adequate time resolution for monitoring the kinetics of Pt NP coagulation.

AB - Over the past few years, the organometalled compounds, including ruthenium, gained a lot of attention as anticancer agents. We report on the clioquinol ruthenium complex [Ru(eta6-p-cymene)(Cq)Cl] as a potent inhibitor of cathepsin B, a lysosomal cysteine peptidase, involved in tumour cell invasion and metastasis. In the low micromolar concentration range, the clioquinol-ruthenium complex did not exhibit cytotoxic effects on MCF-10A neoT and U-87 MG cells; it did, however, significantly reduce their ability for extracellular matrix degradation and invasiveness in two independent cell-based models, measuring either electrical impedance in real time or the growth of multicellular tumour spheroids implanted in Matrigel, a model representing the extracellular matrix. These results establish ruthenium based organometallic compounds as promising candidates for further pre-clinical studies as anticancer therapeutics.

AB - The phosphorus interhalides [PBr4][IBr2] (1) and [PBr4]2[I5Br7] (2) were prepared by reaction of PBr5 and the interhalogen IBr in the ionic liquid [MeBu3N][N(Tf)2] (N(Tf)2: bis(trifluoromethylsulfonyl)amide). [PBr4][IBr2] (1) consists of tetrahedral [PBr4]+ cations and linear [IBr2]- anions. [PBr4]2[I5Br7] (2) also contains [PBr4]+ cations as well as the iodine bromide anion [I5Br7]2-. The latter represents the yet largest known polyiodinebromide. Moreover, (2) shows remarkable halogen release (IBr and Br2) of 96.8 wt% below 300 degrees C. For the ternary system P-Br-I, (1) and (2) are the first compounds that were characterized by crystal structure analysis. Composition, bonding situation and properties were further validated by energy dispersive X-ray (EDX) analysis, thermogravimetry (TG) and Raman spectroscopy. PMID- 27711844 TI - Femtosecond photodissociation dynamics of 1,4-diiodobenzene by gas-phase X-ray scattering and photoelectron spectroscopy. AB - We present a multifaceted investigation into the initial photodissociation dynamics of 1,4-diiodobenzene (DIB) following absorption of 267 nm radiation. We combine ultrafast time-resolved photoelectron spectroscopy and X-ray scattering experiments performed at the Linac Coherent Light Source (LCLS) to study the initial electronic excitation and subsequent rotational alignment, and interpret the experiments in light of Complete Active Space Self-Consistent Field (CASSCF) calculations of the excited electronic landscape. The initially excited state is found to be a bound 1B1 surface, which undergoes ultrafast population transfer to a nearby state in 35 +/- 10 fs. The internal conversion most likely leads to one or more singlet repulsive surfaces that initiate the dissociation. This initial study is an essential and prerequisite component of a comprehensive study of the complete photodissociation pathway(s) of DIB at 267 nm. Assignment of the initially excited electronic state as a bound state identifies the mechanism as predissociative, and measurement of its lifetime establishes the time between excitation and initiation of dissociation, which is crucial for direct comparison of photoelectron and scattering experiments. PMID- 27711845 TI - Single oxygen generation sensitized by spiro(dipyridinogermole)(dithienogermole)s. AB - Three spiro(dipyridinogermole)(dithienogermole) derivatives (1-3), including newly prepared spiro(dipyridinogermole)[di(2-pyridyl)dithienogermole] (3), were examined as photosensitizers for singlet oxygen (1O2) generation in dichloromethane-methanol. Irradiation of their air-saturated solutions led to the generation of 1O2, which was readily trapped by well-known scavengers, dihydronaphthoquinone (DHN) and diphenylisobenzofuran (DPBF). Spiro(dipyridinogermole)[bis(n-hexylbithiophenyl)dithienogermole] (2) showed the best performance with a first-order rate constant that was higher than that of tetraphenylporphyrin (TPP), an efficient photosensitizer for 1O2 generation. This is ascribable to the efficient intersystem crossing characteristic of the dipyridinogermole unit. The quantum yield of 1O2 generation was phiDelta = 0.72 for 2, relative to that for rose bengal (RB) in methanol as reference (phiDelta = 0.8).

AB - Two isostructural vanadium-based metal-organic polyhedra (denoted as VMOP-16 and VMOP-17) were synthesized by a solvothermal method, which are built from unprecedented {V7} isopolyoxometalate clusters and dicarboxylate ligands.

PMID- 27711847 TI - Atom tunnelling in the reaction NH3+ + H2 -> NH4+ + H and its astrochemical relevance. AB - The title reaction is involved in the formation of ammonia in the interstellar medium. We have calculated thermal rates including atom tunnelling using different rate theories. Canonical variational theory with microcanonically optimised multidimensional tunnelling was used for bimolecular rates, modelling the gas-phase reaction and also a surface-catalysed reaction of the Eley-Rideal type. Instanton theory provided unimolecular rates, which model the Langmuir Hinshelwood type surface reaction. The potential energy was calculated on the CCSD(T)-F12 level of theory on the fly. We report thermal rates and H/D kinetic isotope effects. The latter have implications for observed H/D fractionation in molecular clouds. Tunnelling causes rate constants to be sufficient for the reaction to play a role in interstellar chemistry even at cryogenic temperature. We also discuss intricacies and limitations of the different tunnelling approximations to treat this reaction, including its pre-reactive minimum. PMID- 27711849 TI - Novel photochemistry of molecular polaritons in optical cavities. AB - Violations of the Born-Oppenheimer approximation (BOA) and the consequent nonadiabatic dynamics have long been an object of intense study. Recently, such dynamics have been induced via strong coupling of the molecule to a high amplitude (spatially confined) mode of the electromagnetic field in optical cavities. However, the effects of a cavity on a pre-existing avoided crossing or conical intersection are relatively unexplored. The dynamics of molecules dressed by cavity modes are usually calculated by invoking the rotating wave approximation (RWA), which greatly simplifies the calculation but breaks down when the cavity mode frequency is higher than the relevant material frequencies. We develop a protocol for computing curve crossing dynamics in an optical cavity by exploiting a recently-developed method of solving the quantum Rabi model without invoking the RWA. The method is demonstrated for sodium iodide. PMID- 27711848 TI - Metabolism and growth inhibitory activity of cranberry derived flavonoids in bladder cancer cells. AB - In the present study, anti-proliferative activities of cranberry derived flavonoids and some of their in vivo metabolites were evaluated using a panel of human bladder tumor cell lines (RT4, SCABER, and SW-780) and non-tumorigenic immortalized human uroepithelial cells (SV-HUC). Among the compounds tested, quercetin 3-O-glucoside, isorhamnetin (3'-O-methylquercetin), myricetin and quercetin showed strong concentration-dependent cell growth inhibitory activities in bladder cancer cells with IC50 values in a range of 8-92 MUM. Furthermore, isorhamnetin and myricetin had very low inhibitory activity against SV-HUC even at very high concentrations (>200 MUM) compared to bladder cancer cells, indicating that their cytotoxicity is selective for cancer cells. To determine whether the differential cell growth inhibitory effects of isomeric flavonoids quercetin 3-O-glucoside (active) and hyperoside (quercetin 3-O-galactoside) (inactive) are related to their metabolism by the cancer cells, SW-780 cells were incubated with these compounds and their metabolism was examined by LC-MS/MS. Compared to quercetin 3-O-glucoside, hyperoside undergoes relatively less metabolic biotransformation (methylation, glucuronidation and quinone formation). These data suggest that isorhamnetin and quercetin 3-O-glucoside may be the active forms of quercetin in prevention of bladder cancer in vivo and emphasize the importance of metabolism for the prevention of bladder cancer by diets rich in cranberries. PMID- 27711850 TI - Effect of tomato juice consumption on the plasmatic lipid profile, hepatic HMGCR activity, and fecal short chain fatty acid content of rats. AB - The aims of the present study were to ascertain, indirectly, the prebiotic role of tomato juice, by analyzing its effect on the content of short chain fatty acids (SCFA) in feces of rats, and to determine the plausible mechanisms related to the hypocholesterolemic effects of tomato juice and lycopene, evaluating the activity of hepatic HMGCR and the formation of propionic acid. Two commercially available tomato juices with differing contents of lycopene (low and high lycopene contents: Llyc and Hlyc tomato juices) were used. Sprague-Dawley male rats were randomly divided into three experimental groups (n = 8): control group, normal diet and water; group 1, normal diet and Llyc tomato juice; and group 2, normal diet and Hlyc tomato juice, which were fed ad libitum for three weeks. Feces were collected at the beginning and the end of the study to determine SCFA, and blood and liver were obtained (after sacrificing the animals) to analyze the lipid plasmatic parameters and the HMGCR activity and total cholesterol, respectively. No significant differences were observed in the plasmatic parameters, except that HDL-cholesterol increased significantly after consumption of both tomato juices. Lycopene was accumulated in the liver in proportion to the amount ingested, and was observed to have an inhibitory effect on the HMGCR enzyme, according to the amount of lycopene in the liver. In relation to the SCFA in feces, no differences were observed in acetate and propionate after the consumption of tomato juice, but a significant increase in butyrate was observed in group 2 after the intake of Hlyc tomato juice. The content of this carboxylic acid together with excreted lycopene in feces could have a beneficial effect on colonic cells. PMID- 27711851 TI - Dissipative dynamics at conical intersections: simulations with the hierarchy equations of motion method. AB - The effect of a dissipative environment on the ultrafast nonadiabatic dynamics at conical intersections is analyzed for a two-state two-mode model chosen to represent the S2(pipi*)-S1(npi*) conical intersection in pyrazine (the system) which is bilinearly coupled to infinitely many harmonic oscillators in thermal equilibrium (the bath). The system-bath coupling is modeled by the Drude spectral function. The equation of motion for the reduced density matrix of the system is solved numerically exactly with the hierarchy equation of motion method using graphics-processor-unit (GPU) technology. The simulations are valid for arbitrary strength of the system-bath coupling and arbitrary bath memory relaxation time. The present computational studies overcome the limitations of weak system-bath coupling and short memory relaxation time inherent in previous simulations based on multi-level Redfield theory [A. Kuhl and W. Domcke, J. Chem. Phys. 2002, 116, 263]. Time evolutions of electronic state populations and time-dependent reduced probability densities of the coupling and tuning modes of the conical intersection have been obtained. It is found that even weak coupling to the bath effectively suppresses the irregular fluctuations of the electronic populations of the isolated two-mode conical intersection. While the population of the upper adiabatic electronic state (S2) is very efficiently quenched by the system-bath coupling, the population of the diabatic pipi* electronic state exhibits long lived oscillations driven by coherent motion of the tuning mode. Counterintuitively, the coupling to the bath can lead to an enhanced lifetime of the coherence of the tuning mode as a result of effective damping of the highly excited coupling mode, which reduces the strong mode-mode coupling inherent to the conical intersection. The present results extend previous studies of the dissipative dynamics at conical intersections to the nonperturbative regime of system-bath coupling. They pave the way for future first-principles simulations of femtosecond time-resolved four-wave-mixing spectra of chromophores in condensed phases which are nonperturbative in the system dynamics, the system bath coupling as well as the field-matter coupling. PMID- 27711852 TI - Microbial toxicity and biodegradability of perfluorooctane sulfonate (PFOS) and shorter chain perfluoroalkyl and polyfluoroalkyl substances (PFASs). AB - Perfluorooctane sulfonate (PFOS) and related perfluoroalkyl and polyfluoroalkyl substances (PFASs) are emerging contaminants that have been widely applied in consumer and industrial applications for decades. However, PFOS has raised public concern due to its high bioaccumulative character, environmental persistence, and toxicity. Shorter PFASs such as perfluorobutane sulfonate (PFBS) and polyfluoroalkyl compounds have been proposed as alternatives to PFOS but it is unclear whether these fluorinated substances pose a risk for public health and the environment. The objective of this research was to investigate the microbial toxicity and the susceptibility to microbial degradation of PFOS and several related fluorinated compounds, i.e., short-chain perfluoroalkyl and polyfluoroalkyl sulfonic and carboxylic acids. None of the compounds tested were toxic to the methanogenic activity of anaerobic wastewater sludge even at very high concentrations (up to 500 mg L-1). All PFASs evaluated were highly resistant to microbial degradation. PFOS was not reductively dehalogenated by the anaerobic microbial consortium even after very long periods of incubation (3.4 years). Similarly, the tested short chain perfluoroalkyl substances (i.e., PFBS and trifluoroacetic acid) and a polyfluoroalkyl PFOS analogue, 6 : 2 fluorotelomer sulfonic acid (FTSA) were also resistant to anaerobic biodegradation. Likewise, no conclusive evidence of microbial degradation was observed under aerobic conditions for any of the short-chain perfluoroalkyl and polyfluoroalkyl carboxylic acids tested after 32 weeks of incubation. Collectively, these results indicate that PFOS and its alternatives such as short chain perfluoroalkyl sulfonates and carboxylates and their polyfluorinated homologues are highly resistant to microbial degradation. PMID- 27711853 TI - Strong-field-induced wave packet dynamics in carbon dioxide molecule. AB - Temporal evolution of electronic and nuclear wave packets created in strong-field excitation of the carbon dioxide molecule is studied employing momentum-resolved ion spectroscopy and channel-selective Fourier analysis. Combining the data obtained with two different pump-probe set-ups, we observed signatures of vibrational dynamics in both, ionic and neutral states of the molecule. We consider far-off-resonance two-photon Raman scattering to be the most likely mechanism of vibrational excitation in the electronic ground state of the neutral CO2. Using the measured phase relation between the time-dependent yields of different fragmentation channels, which is consistent with the proposed mechanism, we suggest an intuitive picture of the underlying vibrational dynamics. For ionic states, we found signatures of both, electronic and vibrational excitations, which involve the ground and the first excited electronic states, depending on the particular final state of the fragmentation. While our results for ionic states are consistent with the recent observations by Erattupuzha et al. [J. Chem. Phys.144, 024306 (2016)], the neutral state contribution was not observed there, which we attribute to a larger bandwidth of the 8 fs pulses we used for this experiment. In a complementary measurement employing longer, 35 fs pulses in a 30 ps delay range, we study the influence of rotational excitation on our observables, and demonstrate how the coherent electronic wave packet created in the ground electronic state of the ion completely decays within 10 ps due to the coupling to rotational motion. PMID- 27711854 TI - Towards efficient time-resolved X-ray absorption studies of electron dynamics at photocatalytic interfaces. AB - We present a picosecond time-resolved X-ray absorption spectroscopy (tr-XAS) setup designed for synchrotron-based studies of interfacial photochemical dynamics. The apparatus combines a high power, variable repetition rate picosecond laser system with a time-resolved X-ray fluorescence yield detection technique. Time-tagging of the detected fluorescence signals enables the parallel acquisition of X-ray absorption spectra at a variety of pump-probe delays employing the well-defined time structure of the X-ray pulse trains. The viability of the setup is demonstrated by resolving dynamic changes in the fine structure near the O1s X-ray absorption edge of cuprous oxide (Cu2O) after photo excitation with a 355 nm laser pulse. Two distinct responses are detected. A pronounced, quasi-static, reversible change of the Cu2O O1s X-ray absorption spectrum by up to ~30% compared to its static line shape corresponds to a redshift of the absorption edge by ~1 eV. This value is small compared to the 2.2 eV band gap of Cu2O but in agreement with previously published results. The lifetime of this effect exceeds the laser pulse-to-pulse period of 8 MUs, resulting in a quasi-static spectral change that persists as long as the sample is exposed to the laser light, and completely vanishes once the laser is blocked. Additionally, a short-lived response corresponding to a laser-induced shift of the main absorption line by ~2 eV to lower energies appears within <200 ps and decays with a characteristic timescale of 43 +/- 5 ns. Both the picosecond rise and nanosecond decay of this X-ray response are simultaneously captured by making use of a time-tagging approach - highlighting the prospects of the experimental setup for efficient probing of the electronic and structural dynamics in photocatalytic systems on multiple timescales. PMID- 27711855 TI - Synthesis, crystal structure and characterization of novel open framework CHA type aluminophosphate involving a chiral diamine. AB - A highly crystalline new precursor of CHA-type zeolite AlPO4-34 was obtained by using an aluminophosphate gel with a chiral diamine [(S)-(+)-1-(2 pyrrolidinylmethyl)pyrrolidine; C9H18N2] as an organic structure directing agent under hydrothermal synthesis conditions. This precursor (called GAM-1) was changed into the zeolite AlPO4-34 which had a high porosity (the Brunauer-Emmett Teller (BET) surface area is approximately 700 m3 g-1) using calcination. The GAM 1 obtained was characterized by various measurements, e.g., powder X-ray diffraction, scanning electron microscopy, and solid-state nuclear magnetic resonance spectroscopy, and so on. Structure determination from powder diffraction data revealed that the new precursor GAM-1 has triclinic symmetry [space group P1[combining macron], a = 9.16535(11) A, b = 9.23042(11) A, c = 9.29228(11) A, alpha = 79.8243(7) degrees , beta = 87.4593(7) degrees , gamma = 86.5365(7) degrees ] and the chemical formula was estimated to be: |Al6P6O24H2F2|(C9H18N2).2.5(H2O). It also revealed that a two edge sharing AlO4F2 octahedron with an [triple bond, length as m-dash]Al-F-Al[triple bond, length as m-dash] bridge was included in the framework. GAM-1 was transformed into AlPO4-34 with rhombohedral symmetry (R3[combining macron]) by elevating temperature to over 400 degrees C. At high temperatures, AlO4F2 octahedron connectivity was changed into an AlO4 tetrahedron. The crystal structure of the dehydrated AlPO4 34 changed back to a triclinic symmetry (P1) model again after rehydration in the atmosphere.

AB - Outer sphere electron transfer between two ions in aqueous solution is a rare event on the time scale of first principles molecular dynamics simulations. We have used transition path sampling to generate an ensemble of reactive trajectories of the self-exchange reaction between a pair of Ru2+ and Ru3+ ions in water. To distinguish between the reactant and product states, we use as an order parameter the position of the maximally localised Wannier center associated with the transferring electron. This allows us to align the trajectories with respect to the moment of barrier crossing and compute statistical averages over the path ensemble. We compare our order parameter with two typical reaction coordinates used in applications of Marcus theory of electron transfer: the vertical gap energy and the solvent electrostatic potential at the ions.

AB - A super-stable multifunctional terbium(iii)-organic framework, namely {[Tb(TATAB) (H2O)2].NMP.H2O}n (Tb-MOF, H3TATAB = 4,4',4''-s-triazine-1,3,5-triyltri-m aminobenzoic acid, NMP = N-methyl-2-pyrrolidone) was synthesized. Tb-MOF exhibits a 2D sql structure with binuclear [Tb2(COO)4(H2O)4]2+ units as 4-connected nodes, and free water and NMP molecules are inserted between 2D layers through hydrogen bonding interactions, forming a sandwich-type architecture. Observably, such a framework remains intact in a remarkable variety of environments such as common solvents and aqueous solutions with metal cations and inorganic anions, as well as with a pH ranging from 1 to 13. In particular, Tb-MOF can not only detect small organic molecules, metal cations and inorganic anions with high sensitivity and high selectivity, but also can accurately detect explosive 2-nitrophenol, 3 nitrophenol, 4-nitrophenol and 2,4,6-trinitrophenol in water. Its luminescence quenching response to Fe3+ and Cr2O72- ions can be explained in terms of the competitive absorption mechanism. In addition, the luminescence intensity of Tb MOF is strongly correlated with the pH value in a pH range from 1 to 13. Thus, this material can be potentially used as a multi-responsive luminescent sensor.

AB - Yb3+/Er3+ co-doped La2.4Mo1.6O8 up-conversion phosphors with thermometric properties were synthesized by a conventional solid-state reaction. The optimal synthesis conditions for the pure phase have been determined by varying the types and contents of fluxes. Structural studies verify that all samples retain the same face-centered cubic structure, and the morphology via SEM observation also verified the cubic-like crystal growth behaviour. Yb3+/Er3+ co-doped La2.4Mo1.6O8 phosphors mainly emit green emission peaks, ascribed to the emission from the excited states 2H11/2 and 4S3/2 to the ground state 4I15/2 of Er3+ ion, and the weak red emission from the excited state 4F9/2 to the ground state 4I15/2 of Er3+ ion when they are excited by 980 nm laser diodes. The up-conversion process has been discussed in detail by pump-power dependence of luminescence intensities and further explained via the energy level diagram. The temperature-dependence properties of La2.4Mo1.6O8 phosphors were investigated in detail, which show their potential prospect in temperature-sensing applications.

AB - The increasing interest in producing bimetallic nanoparticles and utilizing them in modern technologies sets the demand for fast and affordable characterization of these materials. To date Scanning Transmission Electron Microscopy (STEM) coupled to energy dispersive X-ray spectroscopy is usually used to determine the size and composition of alloy nanoparticles, which is time-consuming and expensive. Here electrochemical single nanoparticle analysis is presented as an alternative approach to infer the particle size and composition of alloy nanoparticles, directly in a dispersion of these particles. As a proof of concept, 14 nm sized Ag0.73Au0.27 alloy nanoparticles are analyzed using a combination of chronoamperometric single nanoparticle analysis and cyclic voltammetry ensemble studies. It is demonstrated that the size, the alloying and the composition can all be inferred using this approach. Thus, the electrochemical characterization of single bimetallic alloy nanoparticles is suggested here as a powerful and convenient complement or alternative to TEM characterization of alloy nanoparticles. PMID- 27711863 TI - Bacterial components are the major contributors to the macrophage stimulating activity exhibited by extracts of common edible mushrooms. AB - Recent studies have indicated that a major contributor to the innate immune enhancing properties of some medicinal plants is derived from the cell wall components of bacteria colonizing these plants. The purpose of the current study was to assess if the bacteria present within edible and medicinal mushrooms substantially contribute to the innate immune stimulating potential of these mushrooms. Whole mushrooms from thirteen types of edible fungi and individual parts from Agaricus bisporus were analyzed for in vitro macrophage activation as well as bacterial lipopolysaccharides (LPS) content, cell load, and community composition. Substantial variation between samples was observed in macrophage activation (over 500-fold), total bacterial load (over 200-fold), and LPS content (over 10 million-fold). Both LPS content (rho = 0.832, p < 0.0001) and total bacterial load (rho = 0.701, p < 0.0001) correlated significantly with macrophage activation in the whole mushroom extracts. Extract activity was negated by treatment with NaOH, conditions that inactivate LPS and other bacterial components. Significant correlations between macrophage activation and total bacterial load (rho = 0.723, p = 0.0001) and LPS content (rho = 0.951, p < 0.0001) were also observed between different tissues of Agaricus bisporus. Pseudomonas and Flavobacterium were the most prevalent genera identified in the different tissue parts and these taxa were significantly correlated with in vitro macrophage activation (rho = 0.697, p < 0.0001 and rho = 0.659, p = 0.0001, respectively). These results indicate that components derived from mushroom associated bacteria contribute substantially to the innate immune enhancing activity exhibited by mushrooms and may result in similar therapeutic actions as reported for ingestion of bacterial preparations such as probiotics. PMID- 27711864 TI - Potassium uranyl borate 3D framework compound resulted from temperature directed hydroborate condensation: structure, spectroscopy, and dissolution studies. AB - The equatorial coordination nature of the uranyl unit has resulted in only three uranyl borate 3D framework compounds reported so far formed from boric acid flux reactions conducted at 190 degrees C while all others are 2D layers. Here in this work, by increasing the reaction temperature to 250 degrees C, a new potassium uranyl borate K[(UO2)B6O10(OH)] (KUBO-4) framework compound is synthesized that shares the same layer topology with the previously reported 2D layered KUBO-1. The 3D structure of KUBO-4 is achieved by interlayer hydroborate condensation. The KUBO-4 was further characterized with single crystal XRD, SHG and fluorescence spectra, and TG/DSC measurements. A deep understanding regarding the dissolution behaviours of uranyl borate is achieved via solubility studies of the KUBO-1 and KUBO-4 performed using a combination of ICP-MS, powder XRD, and fluorescence spectroscopy techniques. The results confirm the lack of stability of borates in aqueous solutions with the presence of coordinating ligands in the environment regardless of the structure types.

In both cases an appreciably high growth rate of ~1.2 A per cycle is achieved. The spinel-structured Mn3O4 thin films are shown to be ferrimagnetic with the transition temperature determined to be at ~47 K.

Analysis of the experimental data is supported by ab initio coupled-cluster calculations evaluating excited state energies and the evolution of several excited state physical properties as a function of N-H/N-CH3 bond extension - a critical reaction coordinate. The use of site-selective methylation brings considerable new insight to the existing body of literature concerning photochemical dynamics in the related system aniline at similar excitation wavelengths. The present work also builds on our own previous investigations in the same species at 250 nm. The TRPEI method provides highly differential energy- and angle-resolved data and, in particular, the temporal evolution of the photoelectron angular distributions afforded by the imaging approach offers much of the new dynamical information. In particular, we see no clear evidence of the second excited 2pipi* state non-adiabatically coupling to the lower-lying S1(pipi*) state or the mixed Rydberg/valence S2(3s/pisigma*) state. This, in turn, potentially raises some unresolved questions about the overall nature of the dynamics operating in these systems, especially in regard to the 2pipi* state's ultimate fate. More generally, the findings for the aromatic systems N,N DMA and 3,5-DMA, taken along with our recent TRPEI results for several aliphatic amine species, highlight interesting questions about the nature of electronic character evolution in mixed Rydberg-valence states as a function of certain key bond extensions and the extent of system conjugation. We begin exploring these ideas computationally for a systematically varied series of tertiary amines.

AB - The detailed mechanisms of the dehydrogenation of benzyl alcohol with N2O as the hydrogen acceptor catalyzed by the rhodium(i) carbene complex for the formation of the corresponding carboxylic acid or ester have been investigated via density functional theory (DFT) calculations at the M06 level of theory. Three cycles were considered for the formation of benzaldehyde, benzyl benzoate and benzoic acid. On the basis of the calculations, the rate-determining step for these three cycles is involved in N2O activation by the rhodium ammine hydride complex with an activation barrier of only 22.6 kcal mol-1, which is different from the previous mechanism proposed by Gianetti and co-workers, where the hydride is transferred from the Rh atom to the oxygen atom of N2O with a barrier of 30.5 kcal mol-1. In addition, the calculations also demonstrated that one more N2O is necessary to give benzoic acid, and the reaction can only take place under anhydrous conditions. Present calculations are in good agreement with the experimental observations and provide new insights into the dehydrogenation of benzyl alcohol with N2O as the hydrogen acceptor.

AB - Reactions of Sn-S clusters with [IrCl(cod)]2 afforded an Ir-Sn-S cluster with unprecedented topology, {[Ir3(cod)3(MU3-S)2](MU3-S)SnCl}2, in which two [Ir3S2] units and a central [Sn2S2] unit are connected via Ir-S and Ir-Sn bonds. Each of the crystallographically independent Ir atoms exhibits a specific chemical environment. Quantum chemical studies shed light on the electronic structure of the multinary cluster and the Ir-Sn bonds. PMID- 27711870 TI - Comparison of lipases for in vitro models of gastric digestion: lipolysis using two infant formulas as model substrates. AB - The aim of this study was to find a lipase suitable as a surrogate for Human Gastric Lipase (HGL), since the development of predictive gastrointestinal lipolysis models are hampered by the lack of a lipase with similar digestive properties as HGL. Three potential surrogates for HGL; Rhizopus Oryzae Lipase (ROL), Rabbit Gastric Lipase (RGL) and recombinant HGL (rHGL), were used to catalyze the in vitro digestion of two infant formulas (a medium-chain triacylglyceride enriched formula (MC-IF) and a predominantly long-chain triacylglyceride formula (LC-IF)). Digesta were withdrawn after 0, 5, 15, 30, 60 min of gastric digestion and after 90 or 180 min of intestinal digestion with or without the presence of pancreatic enzymes, respectively. The digesta were analyzed by scanning electron microscopy and gas chromatography to quantify the release of fatty acids (FAs). Digestions of both formulas, catalyzed by ROL, showed that the extent of gastric digestion was higher than expected from previously published in vivo data. ROL was furthermore insensitive to FA chain length and all FAs were released at the same pace. RGL and rHGL favoured the release of MC-FAs in both formulas, but rHGL did also release some LC-FAs during digestion of MC-IF, whereas RGL only released MC-FAs. Digestion of a MC-IF by HGL in vivo showed that MC-FAs are preferentially released, but some LC-FAs are also released. Thus of the tested lipase rHGL replicated the digestive properties of HGL the best and is a suitable surrogate for HGL for use in in vitro gastrointestinal lipolysis models. PMID- 27711872 TI - Demonstration of intramolecular energy transfer in asymmetric bimetallic ruthenium(ii) complexes. AB - A new family of bimetallic Ru(ii) complexes derived from an asymmetric bridging ligand (tpy-Hbzim-dipy) consisting of both bipyridine and terpyridine chelating sites covalently connected via phenyl-imidazole spacer were designed in this work to demonstrate intramolecular energy transfer from one component to the other in asymmetric dyads. To fine tune the photo-redox properties, both bidentate and tridentate terminal ligands in the complexes were varied systematically. Both steady state and time-resolved luminescence spectral results indicated photo induced intramolecular energy transfer from the excited MLCT state of the [(bpy/phen)2RuII(dipy-Hbzim-tpy)] component to the MLCT state of the tpy containing unit [(dipy-Hbzim-tpy)RuII(tpy-PhCH3/H2pbbzim)] in dyads with rate constant values on the order of 106-107 s-1. Temperature-dependent luminescence studies indicated an enhancement in the luminescence intensity and excited state lifetimes upon decreasing the temperature. PMID- 27711873 TI - Synthesis of a new class of silsesquioxanes with alkynyl and germyl functionality. AB - Although there are a variety of functional compounds in the vast family of silsesquioxanes (POSS), the number of protocols describing specific monosubstituted silsesquioxanes is limited. There are even fewer reports on alkynyl and/or germyl functionalities appearing together with the POSS compounds. Here, a series of novel kinds of cubic monosubstituted POSS bearing alkynyl and germyl functionality in one molecule are reported. These compounds were synthesized by effective germylative coupling of terminal alkynes with vinylgermanes in the presence of a Ru-H complex. The structures of the products were determined. Moreover, stoichiometric reactions of a complex possessing Ru-Ge were also performed to propose the general mechanistic scheme of this reaction. PMID- 27711871 TI - On the mechanism of electrochemical vesicle cytometry: chromaffin cell vesicles and liposomes. AB - The mechanism of mammalian vesicle rupture onto the surface of a polarized carbon fiber microelectrode during electrochemical vesicle cytometry is investigated. It appears that following adsorption to the surface of the polarized electrode, electroporation leads to the formation of a pore at the interface between a vesicle and the electrode and this is shown to be potential dependent. The chemical cargo is then released through this pore to be oxidized at the electrode surface. This makes it possible to quantify the contents as it restricts diffusion away from the electrode and coulometric oxidation takes place. Using a bottom up approach, lipid-only transmitter-loaded liposomes were used to mimic native vesicles and the rupture events occurred much faster in comparison with native vesicles. Liposomes with added peptide in the membrane result in rupture events with a lower duration than that of liposomes and faster in comparison to native vesicles. Diffusional models have been developed and suggest that the trend in pore size is dependent on soft nanoparticle size and diffusion of the content in the nanometer vesicle. In addition, it appears that proteins form a barrier for the membrane to reach the electrode and need to move out of the way to allow close contact and electroporation. The protein dense core in vesicles matrixes is also important in the dynamics of the events in that it significantly slows diffusion through the vesicle. PMID- 27711874 TI - Gold nanoparticles supported by imidazolium-based porous organic polymers for nitroarene reduction. AB - Two imidazolium-based porous organic polymers (Im-POP-1 and Im-POP-2) were synthesized through the Yamamoto reaction of different molar ratios of 1,3-bis(4 bromophenyl)imidazolium bromide and tetrakis(4-bromophenyl)methane, subsequent anion exchange with HAuCl4 and reduction with NaBH4 produced well-dispersed gold nanoparticles (NPs), Au@Im-POP-1 and Au@Im-POP-2. These NPs possess a small size and narrow size distribution, their application in the reduction of nitroarenes was evaluated, and the reduction process was tracked by 13C NMR experiments for reaction mechanism studies. In comparison with gold NPs supported by a non-ionic analogue from the Yamamoto reaction of tetrakis(4-bromophenyl)methane (Au@POP TPM), Au@Im-POP-2 exhibits high catalytic activity, good selectivity of aniline and superior recyclability in nitrobenzene reduction. The gold NPs in Au@Im-POP-2 increase slightly after four consecutive reaction runs, while an apparent agglomeration of NPs in Au@POP-TPM was observed after the second run. This research provides a new type of support for the stabilization of gold NPs and for the improvement of catalytic performances. PMID- 27711875 TI - Classical to quantum mechanical tunneling mechanism crossover in thermal transitions between magnetic states. AB - Transitions between states of a magnetic system can occur by jumps over an energy barrier or by quantum mechanical tunneling through the energy barrier. The rate of such transitions is an important consideration when the stability of magnetic states is assessed for example for nanoscale candidates for data storage devices. The shift in transition mechanism from jumps to tunneling as the temperature is lowered is analyzed and a general expression derived for the crossover temperature. The jump rate is evaluated using a harmonic approximation to transition state theory. First, the minimum energy path for the transition is found with the geodesic nudged elastic band method. The activation energy for the jumps is obtained from the maximum along the path, a saddle point on the energy surface, and the eigenvalues of the Hessian matrix at that point as well as at the initial state minimum used to estimate the entropic pre-exponential factor. The crossover temperature for quantum mechanical tunneling is evaluated from the second derivatives of the energy with respect to orientation of the spin vector at the saddle point. The resulting expression is applied to test problems where analytical results have previously been derived, namely uniaxial and biaxial spin systems with two-fold anisotropy. The effect of adding four-fold anisotropy on the crossover temperature is demonstrated. Calculations of the jump rate and crossover temperature for tunneling are also made for a molecular magnet containing an Mn4 group. The results are in excellent agreement with previously reported experimental measurements on this system. PMID- 27711876 TI - Evaluation of bis-cyclometalated alkynylgold(iii) sensitizers for water photoreduction to hydrogen. AB - Well-defined gold sensitizers for hydrogen production from water remain extremely rare despite decades of interest, and are currently limited to systems based on ruthenium, iridium or platinum complexes. This report details the synthesis and characterization of a series of neutral cyclometalated gold(iii) complexes of the type [(RC^N^CR)Au(C[triple bond, length as m-dash]C-R')] (R = H or tert-butyl group; R' = aryl groups) that have been found to be good candidates to function as harvesting materials in light-induced electron transfer reactions. We established the efficacy of systems with these gold(iii) complexes as photosensitizers (PSs) in the production of renewable hydrogen in the presence of [Co(2,2'-bipyridine)3]Cl2 or [Rh(4,4'-di-tert-butyl-2,2'-bipyridine)3](PF6)3 as a H2-evolved catalyst and triethanolamine (TEOA) as a sacrificial electron donor in acetone-water solution. All complexes are active, and there is a more than threefold increase over other candidates in photocatalytic H2 generation activity. Under the optimal reaction conditions, hydrogen evolution took place through a photochemical route with the highest efficiency and with a turnover number (TON) of up to 1441.5 relative to the sensitizer over 24 hours. In the initial photochemical path, the reductive quenching of the excited gold(iii) complex by TEOA due to the latter's greater concentration in the system followed by electron transfer to the catalyst species is proposed to be the dominant mechanism. A photo-to-H2 quantum yield of approximately 13.7% was attained when illuminated with monochromatic light of 400 nm. Such gold(iii) complexes have demonstrated significant utility in solar-to-hydrogen reactions and thus represent a new effective class of light-harvesting materials. These results open possibilities for pursuing more efficient photosensitizers featuring gold(iii) complexes in photocatalytic solar energy conversion. PMID- 27711877 TI - Rare-earth metal diisopropylamide-catalyzed intramolecular hydroamination. AB - Rare-earth metal diisopropylamide complexes LiLn(NiPr2)4(THF) (Ln = Sc, Y, La), [LiY(NiPr2)4]n, NaLn(NiPr2)4(THF) (Ln = Sc, Y), Sc(NiPr2)3(THF) and Ce(NiPr2)4 were screened as catalysts for the intramolecular hydroamination/cyclization (IHC) of 1-amino-2,2-dimethyl-4-pentene, 1-amino-2,2-diphenyl-4-pentene, and 1 amino-2,2-diphenyl-5-hexene at ambient and moderately increased temperature of 60 degrees C in C6D6. The lithium ate complexes displayed the most efficient precatalysts with high conversion rates at 60 degrees C for the phenyl substituted substrates and Ln = Y and La, affording turnover frequencies Nt as high as 164 h-1. The catalytic activity could be increased by employing THF-free complex [LiY(NiPr2)4]n (Nt = 45.8 h-1 at 26 degrees C; 34.1 h-1 for LiY(NiPr2)4(THF)). In situ generation of putative LiY(NiPr2)4(THF) from YCl3(THF)3.3 and four equivalents of LiNiPr2 (LDA) in C6D6 generated a catalyst revealing Nt comparable to pre-isolated crystallized LiY(NiPr2)4(THF) but yielding even higher substrate conversion. The IHC reactions were also examined for rare-earth metal bis(trimethylsilyl)amide catalysts Ln[N(SiMe3)2]3 (Ln = Sc, Y, La) as well as for LDA using the same reaction conditions, revealing overall superior activity of the silylamide derivatives but poor performance of LDA compared to the rare-earth metal diisopropylamide complexes LiLn(NiPr2)4(THF). Cyclization of 1-amino-2,2-diphenyl-5-hexene to the 6-membered heterocycle 2 methyl-4,4-diphenylpiperidine by lanthanum derivative LiLa(NiPr2)4(THF) was accompanied by a competitive isomerization reaction affording max. 20% of 1-amino 2,2-diphenyl-4-hexene after 2 h at 60 degrees C. Crystalline tetravalent Ce(NiPr2)4 showed a better IHC performance than crystalline trivalent Sc(NiPr2)3(THF) as preliminary examined for 1-amino-2,2-diphenyl-4-pentene at 26 degrees C (Nt = 5.6 and 0.9 h-1, respectively), but cyclization came to a halt after 2 h, probably due to decomposition of the catalyst.

The molecular structure of this intensely red coloured nanoscale Cu2S mimic was established by single crystal X-ray diffraction. PMID- 27711880 TI - Facile preparation of NiCo2O4@rGO composites for the removal of uranium ions from aqueous solutions. AB - A hierarchical structure of NiCo2O4@rGO composite has been fabricated, with its structure and morphology well characterized by XRD, TEM, XPS and BET. The results proved that the NiCo2O4 nanosheets grow uniformly on both sides of the graphene sheets. In batch adsorption experiments, the effects of equilibrium time, pH and temperature on uranium(vi) adsorption were investigated. The main results show that the NiCo2O4@rGO composite has a higher affinity towards the uptake of uranium(vi) from aqueous solutions. The highest adsorption capacity reached 342.4 mg U g-1 at pH 5.0. Kinetic analysis shows that the adsorption process is described best by a pseudo-second-order kinetic model. The uranium(vi) sorption equilibrium data correlates well with the Langmuir sorption isotherm model in the thermodynamic analysis. Thus, NiCo2O4@rGO composite is an excellent adsorbent for removing uranium(vi) ions. PMID- 27711881 TI - Structural dynamics of photochemical reactions probed by time-resolved photoelectron spectroscopy using high harmonic pulses. AB - Femtosecond ring-opening dynamics of 1,3-cyclohexadiene (CHD) in gas phase upon two-photon excitation at 400 nm (=3.1 eV) was investigated by time-resolved photoelectron spectroscopy using 42 nm (=29.5 eV) high harmonic photons probing the dynamics of the lower-lying occupied molecular orbitals (MOs), which are the fingerprints of the molecular structure. After 500 fs, the photoelectron intensity of the MO constituting the C[double bond, length as m-dash]C sigma bond (sigmaC[double bond, length as m-dash]C) of CHD was enhanced, while that of the MO forming the C-C sigma bond (sigmaCC) of CHD was decreased. The changes in the photoelectron spectra suggest that the ring of CHD opens to form a 1,3,5 hexatriene (HT) after 500 fs. The dynamics of the sigmaC[double bond, length as m dash]C and sigmaCC bands between 200 and 500 fs reflects the ring deformation to a conical intersection between the 21A and 11A potential energy surfaces prior to the ring-opening reaction.

AB - The effect of Mo-substitution was investigated for the LaCoxNiyMozO3 system, obtaining single-phase perovskite for Mo-substitutions up to 20 at%. The crystal structure of the perovskite changed from rhombohedral, orthorhombic to monoclinic with increasing Mo-content. The thermal expansion was suppressed by Mo substitution, while the electrical conductivity was also suppressed, but remained relatively high. PMID- 27711883 TI - Deterministic modeling of the exposure of individual participants in the National Health and Nutrition Examination Survey (NHANES) to polychlorinated biphenyls. AB - A population's exposure to persistent organic pollutants, e.g., polychlorinated biphenyls (PCBs), is typically assessed through national biomonitoring programs, such as the United States National Health and Nutrition Examination Survey (NHANES). To complement statistical methods, we use a deterministic modeling approach to establish mechanistic links between human contaminant concentrations and factors (e.g. age, diet, lipid mass) deemed responsible for the often considerable variability in these concentrations. Lifetime exposures to four PCB congeners in 6128 participants from NHANES 1999-2004 are simulated using the ACC Human model supplied with individualized input parameters obtained from NHANES questionnaires (e.g., birth year, sex, body mass index, dietary composition, reproductive behavior). Modeled and measured geometric mean PCB-153 concentrations in NHANES participants of 13.3 and 22.0 ng g-1 lipid, respectively, agree remarkably well, although lower model-measurement agreement for air, water, and food suggests that this is partially due to fortuitous error cancellation. The model also reproduces trends in the measured data with key factors such as age, parity and sex. On an individual level, 62% of all modeled concentrations are within a factor of three of their corresponding measured values (Spearman rs = 0.44). However, the model attributes more of the inter individual variability to differences in dietary lipid intake than is indicated by the measured data. While the model succeeds in predicting levels and trends on the population level, the accuracy of individual-specific predictions would need to be improved for refined exposure characterization in epidemiological studies. PMID- 27711884 TI - Imaging electrocatalytic processes on single gold nanorods. AB - Imaging electrochemical processes has attracted increasing attention in past decades. Particularly, monitoring electrochemical reactions rapidly at the nano scale is still a challenge due to the ultra-low current detection and long scanning time required. The development of optical techniques provide a new way to demonstrate electrochemical processes through optical signals which enhance sensitivity and spatial resolution. Herein, we developed a novel method to image electrocatalytic processes on single gold nanorods (GNRs) during Cyclic Voltammetry (CV) scanning based on plasmon resonance scattering information by using dark-field microscopy. The electrocatalytic oxidation of hydrogen peroxide was selected as a typical reaction and the catalytic mechanism was revealed using the obtained spectra. Notably, observation on single GNRs avoided the averaging effects in bulk systems and confirmed that the individual nanoparticles had variable catalytic properties with different spectral change during the reaction process. Furthermore, a color-amplified system was introduced to convert light intensity into imaging information via the Matlab program which was able to image thousands of nanoparticles simultaneously. This approach offered the statistical intensity distribution of all of the nanoparticles in a dark-field image which dramatically enhanced the detection accuracy and avoided random events. PMID- 27711885 TI - A passive dosing method to determine fugacity capacities and partitioning properties of leaves. AB - The capacity of leaves to take up chemicals from the atmosphere and water influences how contaminants are transferred into food webs and soil. We provide a proof of concept of a passive dosing method to measure leaf/polydimethylsiloxane partition ratios (Kleaf/PDMS) for intact leaves, using polychlorinated biphenyls (PCBs) as model chemicals. Rhododendron leaves held in contact with PCB-loaded PDMS reached between 76 and 99% of equilibrium within 4 days for PCBs 3, 4, 28, 52, 101, 118, 138 and 180. Equilibrium Kleaf/PDMS extrapolated from the uptake kinetics measured over 4 days ranged from 0.075 (PCB 180) to 0.371 (PCB 3). The Kleaf/PDMS data can readily be converted to fugacity capacities of leaves (Zleaf) and subsequently leaf/water or leaf/air partition ratios (Kleaf/water and Kleaf/air) using partitioning data from the literature. Results of our measurements are within the variability observed for plant/air partition ratios (Kplant/air) found in the literature. Log Kleaf/air from this study ranged from 5.00 (PCB 3) to 8.30 (PCB 180) compared to log Kplant/air of 3.31 (PCB 3) to 8.88 (PCB 180) found in the literature. The method we describe could provide data to characterize the variability in sorptive capacities of leaves that would improve descriptions of uptake of chemicals by leaves in multimedia fate models. PMID- 27711886 TI - Review of chemical and electrokinetic remediation of PCBs contaminated soils and sediments. AB - Polychlorinated biphenyls (PCBs) are manmade organic compounds, and pollution due to PCBs has been a global environmental problem because of their persistence, long-range atmospheric transport and bioaccumulation. Many physical, chemical and biological technologies have been utilized to remediate PCBs contaminated soils and sediments, and there are some emerging new technologies and combined methods that may provide cost-effective alternatives to the existing remediation practice. This review provides a general overview on the recent developments in chemical treatment and electrokinetic remediation (EK) technologies related to PCBs remediation. In particular, four technologies including photocatalytic degradation of PCBs combined with soil washing, Fe-based reductive dechlorination, advanced oxidation process, and EK/integrated EK technology (e.g., EK coupled with chemical oxidation, nanotechnology and bioremediation) are reviewed in detail. We focus on the fundamental principles and governing factors of chemical technologies, and EK/integrated EK technologies. Comparative analysis of these technologies including their major advantages and disadvantages is summarized. The existing problems and future prospects of these technologies regarding PCBs remediation are further highlighted. PMID- 27711887 TI - High-bandwidth detection of short DNA in nanopipettes. AB - Glass or quartz nanopipettes have found increasing use as tools for studying the biophysical properties of DNA and proteins, and as sensor devices. The ease of fabrication, favourable wetting properties and low capacitance are some of the inherent advantages, for example compared to more conventional, silicon-based nanopore chips. Recently, we have demonstrated high-bandwidth detection of double stranded (ds) DNA with microsecond time resolution in nanopipettes, using custom designed electronics. The electronics design has now been refined to include more sophisticated control features, such as integrated bias reversal and other features. Here, we exploit these capabilities and probe the translocation of short dsDNA in the 100 bp range, in different electrolytes. Single-stranded (ss) DNA of similar length are in use as capture probes, so label-free detection of their ds counterparts could therefore be of relevance in disease diagnostics. PMID- 27711889 TI - Probing the excited state relaxation dynamics of pyrimidine nucleosides in chloroform solution. AB - Ultrafast transient electronic and vibrational absorption spectroscopy (TEAS and TVAS) of 2'-deoxy-cytidine (dC) and 2'-deoxy-thymidine (dT) dissolved in chloroform examines their excited-state dynamics and the recovery of ground electronic state molecules following absorption of ultraviolet light. The chloroform serves as a weakly interacting solvent, allowing comparisons to be drawn with prior experimental studies of the photodynamics of these nucleosides in the gas phase and in polar solvents such as water. The pyrimidine base nucleosides have some propensity to dimerize in aprotic solvents, but the monomer photochemistry can be resolved clearly and is the focus of this study. UV absorption at a wavelength of 260 nm excites a 1pipi* <- S0 transition, but prompt crossing of a significant fraction (50% in dC, 17% in dT) of the 1pipi* population into a nearby 1npi* state is too fast for the experiments to resolve. The remaining flux on the 1pipi* state leaves the vertical Franck-Condon region and encounters a conical intersection with the ground electronic state of ethylenic twist character. In dC, the 1pipi* state decays to the ground state with a time constant of 1.1 +/- 0.1 ps. The lifetime of the 1npi* state is much longer in the canonical forms of both molecules: recovery of the ground state population from these states occurs with time constants of 18.6 +/- 1.1 ps in amino-oxo dC and ~114 ps in dT, indicating potential energy barriers to the 1npi*/S0 conical intersections. The small fraction of the imino-oxo tautomer of dC present in solution has a longer-lived 1npi* state with a lifetime for ground state recovery of 193 +/- 55 ps. No evidence is found for photo-induced tautomerization of amino-oxo dC to the imino-oxo form, or for population of low lying triplet states of this nucleoside. In contrast, ~8% of the UV-excited dT molecules access the long-lived T1 (3pipi*) state through the 1npi* state. The primary influence of the solvent appears to be the degree to which it destabilizes the states of 1npi* character, with consequences for the lifetimes of these states as well as the triplet state yields. PMID- 27711888 TI - Energetics of base flipping at a DNA mismatch site confined at the latch constriction of alpha-hemolysin. AB - Unique, two-state modulating current signatures are observed when a cytosine cytosine mismatch pair is confined at the 2.4 nm latch constriction of the alpha hemolysin (alphaHL) nanopore. We have previously speculated that the modulation is due to base flipping at the mismatch site. Base flipping is a biologically significant mechanism in which a single base is rotated out of the DNA helical stack by 180 degrees . It is the mechanism by which enzymes are able to access bases for repair operations without disturbing the global structure of the helix. Here, temperature dependent ion channel recordings of individual double-stranded DNA duplexes inside alphaHL are used to derive thermodynamic (DeltaH, DeltaS) and kinetic (EA) parameters for base flipping of a cytosine at an unstable cytosine cytosine mismatch site. The measured activation energy for flipping a cytosine located at the latch of alphaHL out of the helix (18 +/- 1 kcal mol-1) is comparable to that previously reported for base flipping at mismatch sites from NMR measurements and potential mean force calculations. We propose that the alphaHL nanopore is a useful tool for measuring conformational changes in dsDNA at the single molecule level. PMID- 27711890 TI - Applications: general discussion. PMID- 27711891 TI - Transformation of mackinawite to greigite by trichloroethylene and tetrachloroethylene. AB - Trichloroethylene (TCE) and tetrachloroethylene (PCE) are common ground water contaminants susceptible to reductive dechlorination by FeS (mackinawite) in anaerobic environments. The objective of this study was to characterize the mineral-associated products that form when mackinawite reacts with TCE and PCE. The dissolved products of the reaction included Cl- and Fe2+, and trace amounts of cis 1,2-dichloroethylene (for TCE) and TCE (for PCE). Selected area electron diffraction (SAED) analysis identified greigite as a mackinawite oxidation product formed after reaction between TCE or PCE and FeS over seven weeks. Release of Fe2+ is consistent with the solid state transformation of mackinawite to greigite, resulting in depletion of the solid with Fe. X-ray photoelectron spectroscopy of the sulfur 2p peak showed a shift to a higher binding energy after FeS reacted with TCE or PCE, also observed in other studies of mackinawite oxidation to greigite. The results may help efforts to maintain the reactivity of FeS generated to remediate chlorinated aliphatic contaminants in ground water. PMID- 27711892 TI - Electrochemical transformation of individual nanoparticles revealed by coupling microscopy and spectroscopy. AB - Although extremely sensitive, electrical measurements are essentially unable to discriminate complex chemical events involving individual nanoparticles. The coupling of electrochemistry to dark field imaging and spectroscopy allows the triggering of the electrodissolution of an ensemble of Ag nanoparticles (by electrochemistry) and the inference of both oxidation and dissolution processes (by spectroscopy) at the level of a single nanoparticle. Besides the inspection of the dissolution process from optical scattering intensity, adding optical spectroscopy reveals chemical changes through drastic spectral changes. The behaviours of single NPs and NP agglomerates are differentiated: in the presence of thiocyanate ions, the transformation of Ag single nanoparticles to AgSCN is investigated in the context of plasmonic coupling with the electrode; tentative interpretations for optically unresolved groups of nanoparticles are proposed. PMID- 27711893 TI - Single molecular catalysis of a redox enzyme on nanoelectrodes. AB - Due to a high turnover coefficient, redox enzymes can serve as current amplifiers which make it possible to explore their catalytic mechanism by electrochemistry at the level of single molecules. On modified nanoelectrodes, the voltammetric behavior of a horseradish peroxidase (HRP) catalyzed hydroperoxide reduction no longer presents a continuous current response, but a staircase current response. Furthermore, single catalytic incidents were captured through a collision mode at a constant potential, from which the turnover number of HRP can be figured out statistically. In addition, the catalytic behavior is dynamic which may be caused by the orientation status of HRP on the surface of the electrode. This modified nanoelectrode methodology provides an electrochemical approach to investigate the single-molecule catalysis of redox enzymes. PMID- 27711894 TI - Nanocapillary electrokinetic tracking for monitoring charge fluctuations on a single nanoparticle. AB - We introduce nanoCapillary Electrokinetic Tracking (nanoCET), an optofluidic platform for continuously measuring the electrophoretic mobility of a single colloidal nanoparticle or macromolecule in vitro with millisecond time resolution and high charge sensitivity. This platform is based on using a nanocapillary optical fiber in which liquids may flow inside a channel embedded inside the light-guiding core and nanoparticles are tracked using elastic light scattering. Using this platform we have experimentally measured the electrophoretic mobility of 60 nm gold nanoparticles in an aqueous environment. Further, using numerical simulations, we demonstrate the underlying electrokinetic dynamics inside the nanocapillary and the necessary steps for extending this method to probing single biomolecules, which can be achieved with existing technologies. This achievement will immensely facilitate the daunting challenge of monitoring biochemical or catalytic reactions on a single entity over a wide range of timescales. The unique measurement capabilities of this platform pave the way for a wide range of discoveries in colloid science, analytical biochemistry, and medical diagnostics. PMID- 27711895 TI - Confronting surface hopping molecular dynamics with Marcus theory for a molecular donor-acceptor system. AB - We investigate the performance of fewest switches surface hopping (SH) in describing electron transfer (ET) for a molecular donor-acceptor system. Computer simulations are carried out for a wide range of reorganisation energy (lambda), electronic coupling strength (Hab) and driving force using our recently developed fragment orbital-based SH approach augmented with a simple decoherence correction. This methodology allows us to compute SH ET rates over more than four orders of magnitude, from the sub-picosecond to the nanosecond time regime. We find good agreement with semi-classical ET theory in the non-adiabatic ET regime. The correct scaling of the SH ET rate with electronic coupling strength is obtained and the Marcus inverted regime is reproduced, in line with previously reported results for a spin-boson model. Yet, we find that the SH ET rate falls below the semi-classical ET rate in the adiabatic regime, where the free energy barrier is in the order of kBT in our simulations. We explain this by first signatures of non-exponential population decay of the initial charge state. For even larger electronic couplings (Hab = lambda/2), the free energy barrier vanishes and ET rates are no longer defined. At this point we observe a crossover from ET on the vibronic time scale to charge relaxation on the femtosecond time scale that is well described by thermally averaged Rabi oscillations. The extension of the analysis from the non-adiabatic limit to large electronic couplings and small or even vanishing activation barriers is relevant for our understanding of charge transport in organic semiconductors.

AB - Electrochemical reactions at nanoscale structures possess unique characteristics, e.g. fast mass transport, high signal-to-noise ratio at low concentration, and insignificant ohmic losses even at low electrolyte concentrations. These properties motivate the fabrication of high density, laterally ordered arrays of nanopores, embedding vertically stacked metal-insulator-metal electrode structures and exhibiting precisely controlled pore size and interpore spacing for use in redox cycling. These nanoscale recessed ring-disk electrode (RRDE) arrays exhibit current amplification factors, AFRC, as large as 55-fold with Ru(NH3)62/3+, indicative of capture efficiencies at the top and bottom electrodes, Phit,b, exceeding 99%. Finite element simulations performed to investigate the concentration distribution of redox species and to assess operating characteristics are in excellent agreement with experiment. AFRC increases as the pore diameter, at constant pore spacing, increases in the range 200-500 nm and as the pore spacing, at constant pore diameter, decreases in the range 1000-460 nm. Optimized nanoscale RRDE arrays exhibit a linear current response with concentration ranging from 0.1 MUM to 10 mM and a small capacitive current with scan rate up to 100 V s-1. At the lowest concentrations, the average pore occupancy is ~ 0.13 molecule establishing productive electrochemical signals at occupancies at and below the single molecule level in these nanoscale RRDE arrays.

PMID- 27711899 TI - Stimulated X-ray Raman scattering - a critical assessment of the building block of nonlinear X-ray spectroscopy. AB - With the invention of femtosecond X-ray free-electron lasers (XFELs), studies of light-induced chemical reaction dynamics and structural dynamics reach a new era, allowing for time-resolved X-ray diffraction and spectroscopy. To ultimately probe coherent electron and nuclear dynamics on their natural time and length scales, coherent nonlinear X-ray spectroscopy schemes have been proposed. In this contribution, we want to critically assess the experimental realisation of nonlinear X-ray spectroscopy at current-day XFEL sources, by presenting first experimental attempts to demonstrate stimulated resonant X-ray Raman scattering in molecular gas targets. PMID- 27711900 TI - Stochastic electrochemistry and photoelectrochemistry of colloidal dye-sensitized anatase nanoparticles at a Pt ultramicroelectrode. AB - We report the stochastic interactions between dye sensitized anatase nanoparticles, suspended in a colloid, and a Pt ultramicroelectrode (UME) that result in step-wise behavior in the current vs. time response. The stochastic currents are observed in the dark and under illumination. In the dark, the currents are anodic, consistent with the oxidation of the dye N719 at the Pt surface. The electrochemical behavior of the dye was investigated in MeOH and MeCN with a quasireversible cyclic voltammogram (CV) observed at 1 V s-1. The anodic currents observed in the dark due to nanoparticles (NPs) at the Pt surface are consistent with the CVs in MeOH and MeCN. Under illumination cathodic steps are observed and assigned to the reduction of the oxidized form of the dye generated after electrons are injected into the TiO2 NPs. The colloidal behavior is a strong function of the history of the colloid with illumination time increasing the size of the agglomerates and with larger agglomerates being less photoelectrochemically active. Agglomerates of ca. 100 nm in diameter are proposed to be photoactive entities with a higher probability of detection that contribute to the staircase photocurrent response. PMID- 27711898 TI - Imaging ultrafast excited state pathways in transition metal complexes by X-ray transient absorption and scattering using X-ray free electron laser source. AB - This report will describe our recent studies of transition metal complex structural dynamics on the fs and ps time scales using an X-ray free electron laser source, Linac Coherent Light Source (LCLS). Ultrafast XANES spectra at the Ni K-edge of nickel(ii) tetramesitylporphyrin (NiTMP) were measured for optically excited states at a timescale from 100 fs to 50 ps, providing insight into its sub-ps electronic and structural relaxation processes. Importantly, a transient reduced state Ni(i) (pi, 3dx2-y2) electronic state is captured through the interpretation of a short-lived excited state absorption on the low-energy shoulder of the edge, which is aided by the computation of X-ray transitions for postulated excited electronic states. The observed and computed inner shell to valence orbital transition energies demonstrate and quantify the influence of the electronic configuration on specific metal orbital energies. A strong influence of the valence orbital occupation on the inner shell orbital energies indicates that one should not use the transition energy from 1s to other orbitals to draw conclusions about the d-orbital energies. For photocatalysis, a transient electronic configuration could influence d-orbital energies up to a few eV and any attempt to steer the reaction pathway should account for this to ensure that external energies can be used optimally in driving desirable processes. NiTMP structural evolution and the influence of the porphyrin macrocycle conformation on relaxation kinetics can be likewise inferred from this study. PMID- 27711902 TI - Challenges in nanoelectrochemical and nanomechanical studies of individual anisotropic gold nanoparticles. AB - The characterization of nanoparticles and the correlation of physical properties such as size and shape to their (electro)chemical properties is an emerging field, which may facilitate future optimization and tuning of devices involving nanoparticles. This requires the investigation of individual particles rather than obtaining averaged information on large ensembles. Here, we present atomic force - scanning electrochemical microscopy (AFM-SECM) measurements of soft conductive PDMS substrates modified with gold nanostars (i.e., multibranched Au nanoparticles) in peak force tapping mode, which next to the electrochemical characterization provides information on the adhesion, deformation properties, and Young's modulus of the sample. AFM-SECM probes with integrated nanodisc electrodes (radii < 50 nm) have been used for these measurements. Most studies attempting to map individual nanoparticles have to date been performed at spherical nanoparticles, rather than highly active asymmetric gold nanoparticles. Consequently, this study discusses challenges during the nanocharacterization of individual anisotropic gold nanostars.

AB - Goat meat is extensively known for its interesting nutritional value and for being an important source of protein with high quality. Its food derivatives are, therefore, a good alternative to develop new products addressed to health conscious consumers. In this work, a healthier goat product, namely, a low fat fresh sausage, was produced with the objective of evaluating the effect of inclusion of chitosan on quality, stability and shelf life. Sausages containing 2% chitosan were formulated with different fat levels (5%, 12.5% and 20%, w/w) and stored at 4 degrees C for 15 days. Results indicated the incorporation of 2% (w/w) chitosan was technologically feasible, due to the reduction of microbial growth and lipid oxidation, as well as the enhancement of red color. Additionally, the treated samples improved all the characteristics associated with cooking, showing the ability to bind water and fat and acquiring a firmer texture compared with control samples. Additionally, the reduction of fat content is technologically feasible without negative influences on the final product. PMID- 27711903 TI - Quantification of microbial uptake of quercetin and its derivatives using an UHPLC-ESI-QTOF mass spectrometry assay. AB - A liquid chromatography-mass spectrometry-based method for the quantification of intracellular concentrations of dietary phenolics in bacteria was developed. Using this assay, the time-dependent uptake of quercetin and two of its glycosides into gut microbiota model organisms (Escherichia coli and Bifidobacterium bifidum) under aerobic and anaerobic conditions was studied. For the first time, quantitative data on the uptake of dietary phenols were obtained indicating a time-dependent differential uptake of the dietary compounds. The shape of the uptake curve and the comparative use of bacterial mutants lacking porins OmpFC or the multi-drug efflux pump AcrAB, respectively, along with the identification and quantification of selected bacterial metabolites provided a mechanistic insight into the uptake process.

PMID- 27711906 TI - Proteomic response of inflammatory stimulated intestinal epithelial cells to in vitro digested plums and cabbages rich in carotenoids and polyphenols. AB - Due to their anti-oxidant and anti-inflammatory potential, polyphenol and carotenoid-rich plant foods have been suggested as promising phytochemicals in the prevention of or as adjuvants regarding inflammatory bowel diseases (IBD). In the present study, we investigated whether plum (Italian Plum, Prunus cocomilla), or cabbage (Kale, Brassica oleracea var. sabellica), selected for their high phytochemical content, are able to reduce inflammation in cellular models of the intestinal epithelium, employing proteomic methods. For this purpose, plum/cabbage (carotenoid content: 1.9 mg per 100 g resp. 13 mg per 100 g; polyphenol content: 83 mg per 100 g resp. 27 mg per 100 g) were gastro intestinally digested, and aliquots exposed (18 h) to either a monoculture (Caco 2) or a triple culture (Caco-2/HT-29-MTX (90 : 10, v/v) with THP-1 like macrophages), stimulated (with LPS, TNF-alpha, and IL-1beta) to induce inflammation. Cells (Caco-2, Caco-2/HT-29-MTX, and THP-1) were then harvested separately, and proteomic analyses of total cell extracts were carried out by 2D DIGE. In the monoculture, 68 protein-spots were significantly (p < 0.05, expression ratio >1.5) differentially regulated due to the Kale and Italian plum digesta, and in the co-culture 206 protein-spots, compared to digesta without plum/cabbage. These belonged to 27 (monoculture) and 76 (coculture) uniquely identified proteins, suggesting the coculture to be a more sensitive model. Proteins included antioxidant enzymes such as catalase, superoxide dismutase and glutathione-S-transferases. Only 3 proteins were differentially regulated in the THP-1 cells, perhaps as these were only indirectly exposed. The results show promise regarding some aspects related to IBD complications, however, employing phytochemical-rich food items should be further investigated in in vivo trials. PMID- 27711908 TI - Membrane patches as ion channel probes for scanning ion conductance microscopy. AB - We describe dual-barrel ion channel probes (ICPs), which consist of an open barrel and a barrel with a membrane patch directly excised from a donor cell. When incorporated with scanning ion conductance microscopy (SICM), the open barrel (SICM barrel) serves to measure the distance-dependent ion current for non invasive imaging and positioning of the probe in the same fashion of traditional SICM. The second barrel with the membrane patch supports ion channels of interest and was used to investigate ion channel activities. To demonstrate robust probe control with the dual-barrel ICP-SICM probe and verify that the two barrels are independently addressable, current-distance characteristics (approach curves) were obtained with the SICM barrel and simultaneous, current-time (I-T) traces were recorded with the ICP barrel. To study the influence that the distance between ligand-gated ion channels (i.e., large conductance Ca2+-activated K+ channels/BK channels) and the ligand source (i.e., Ca2+ source) has on channel activations, ion channel activities were recorded at two fixed probe-substrate distances (Dps) with the ICP barrel. The two fixed positions were determined from approach curves acquired with the SICM barrel. One position was defined as the "In-control" position, where the probe was in close proximity to the ligand source; the second position was defined as the "Far" position, where the probe was retracted far away from the ligand source. Our results confirm that channel activities increased dramatically with respect to both open channel probability and single channel current when the probe was near the ligand source, as opposed to when the probe was far away from the ligand source. PMID- 27711907 TI - Influence of the addition of Lactobacillus acidophilus La-05, Bifidobacterium animalis subsp. lactis Bb-12 and inulin on the technological, physicochemical, microbiological and sensory features of creamy goat cheese. AB - The effects of the addition of Lactobacillus acidophilus LA-05, Bifidobacterium animalis subsp. lactis BB-12 and inulin on the quality characteristics of creamy goat cheese during refrigerated storage were evaluated. The manufactured cheeses included the addition of starter culture (Lactococcus lactis subsp. lactis and Lactococcus lactis subsp. cremoris - R-704) (CC); starter culture, L. acidophilus LA-05 and inulin (CLA); starter culture, B. lactis BB-12 and inulin (CBB); or starter culture, L. acidophilus LA-05, B. lactis BB-12 and inulin (CLB). In the synbiotic cheeses (CLA, CBB and CLB), the counts of L. acidophilus LA-05 and B. lactis BB-12 were greater than 6log CFU g-1, the amount of inulin was greater than 6 g per 100 g, and the firmness was reduced. The cheeses evaluated had high brightness values (L*), with a predominance of yellow (b*). CC had higher contents of proteins, lipids and minerals compared to the other cheeses. There was a decrease in the amount of short-chain fatty acids (SCFAs) and an increase of medium-chain (MCFAs) and long-chain fatty acids (LCFAs) in the synbiotic cheeses compared to CC. The amount of conjugated linoleic acid increased in CLA, CBB and CLB. The highest depth of proteolysis and the greatest changes in the release of free amino acids were found in CLB. The addition of inulin and probiotics, alone or in co-culture, did not affect the cheese acceptance. Inulin and probiotics can be used together for the production of creamy goat cheese without negatively affecting the general quality characteristics of the product, and to add value because of its synbiotic potential.

PMID- 27711909 TI - Reduced Levels of Tear Lacritin Are Associated With Corneal Neuropathy in Patients With the Ocular Component of Sjogren's Syndrome. AB - Purpose: To determine whether levels of endogenous tear protein, lacritin, are linked to altered corneal innervation and dry eye severity in patients with Sjogren's syndrome (SS). Methods: Clinical data were obtained from 10 SS and 10 age-matched controls. Enzyme-linked immunosorbent assay was used to assess total tear lacritin extracted from Schirmer strips. Western blot was used to detect active lacritin monomer (~25 kDa), active lacritin fragment (~12-15 kDa), and inactive tissue transglutaminase-generated lacritin (>=40 kDa). In vivo confocal microscopy was used to assess nerve fiber density (NFD) and length (NFL). Relationships between nerve morphology and tear lacritin were examined by Spearman correlation. Diagnostic performance of tear lacritin was analyzed using receiver operating characteristic. Results: Active tear lacritin was significantly reduced in SS patients (3.72 +/- 5.62 [SS] versus 18.17 +/- 4.57 ng/100 ng total tear protein [controls]; P < 0.001), while inactive lacritin was increased (84.99% +/- 11.15% [SS] versus 51.04% +/- 12.03% [controls]; P < 0.001). Nerve fiber density (21.70 +/- 18.93 vs. 31.80 +/- 9.35; P = 0.03) and NFL (4.18 +/- 3.44 vs. 6.54 +/- 2.47; P < 0.05) were significantly decreased in SS patients compared to controls. Reduced NFL (r = 0.74, P < 0.01) and NFD (r = 0.70, P < 0.01) were highly correlated with reduced tear lacritin. Similarly, total tear lacritin was highly correlated with Schirmers (r = 0.77, P < 0.01), ocular staining (r = -0.80, P < 0.01), and corneal sensitivity (r = 0.81, P < 0.01). Tear lacritin showed equivalent or better diagnostic performance compared to traditional clinical measures for SS (100.00% sensitivity, 85.71% specificity, cutoff = 14.50 ng/100 ng tear protein). Conclusions: Reduced tear lacritin levels in SS patients are highly correlated with clinical signs of dry eye, as well as decreased NFD and NFL. Lacritin and its components provide excellent diagnostic sensitivity and specificity in SS.

PMID- 27711912 TI - Association of Changes in Visual Acuity With Vision-Specific Functioning in the Singapore Malay Eye Study. AB - Importance: Longitudinal population-based data on the effect of vision loss on vision-specific functioning (VSF) are scarce, particularly in Asian populations. Objective: To examine the association between changes in presenting visual acuity (PVA) and VSF. Design, Setting, and Participants: Vision-specific functioning of 1895 adults was assessed in the baseline (January 20, 2004-July 31, 2006) and follow-up (June 28, 2010-July 31, 2014) phases of the longitudinal population based Singapore Malay Eye Study. Mean (SD) differences and effect sizes for results of the modified Visual Function Index were calculated for 3 categories of change in PVA in the eye with better vision during the follow-up period (PVA gain of >=2 lines [+0.2 logMAR], no change [PVA between a loss of 2 lines and a gain of 2 lines], and PVA loss of >=2 lines [-0.2 logMAR]). The group with PVA loss was further stratified into incident vision impairment (VI) (baseline PVA >=6/12) and progression of VI (baseline PVA <6/12) that worsened by 2 or more lines at follow-up. Associations between PVA and VSF changes were assessed using multiple linear regression models. Exposures: Presenting visual acuity was measured using a logMAR chart during an ophthalmic examination at baseline and follow-up. Main Outcomes and Measures: Vision-specific functioning and associations between PVA and changes in VSF. Results: Of the 1895 participants (mean [SD] age at baseline, 56.9 [10.1] years; 862 men and 1033 women), at follow-up, 319 (16.8%) had lost 2 or more lines of PVA (mean [SD] PVA loss, 0.34 [0.22] logMAR; P < .001), which was associated with a mean (SD) -0.87 [2.12] logit decrease in VSF (medium effect size, -0.61). Of these 319 participants, 153 (48%) had incident VI and 166 (52%) had progression of VI, which were associated with mean (SD) -1.08 (2.15) (effect size, -0.86) and -0.64 (2.06) (effect size, -0.41) logit reductions in VSF, respectively. In adjusted models, compared with participants with no change in PVA, those who lost 2 or more lines had a significant 117% reduction in VSF (beta, -0.39; 95% CI, -0.62 to -0.16). Older age (-0.55 logit decrease in VSF; 95% CI, -0.66 to -0.43) and female sex (-0.25 logit decrease in VSF; 95% CI, 0.45 to -0.06) were also independently associated with poorer VSF at follow-up (P < .01). Conclusions and Relevance: Approximately 1 in 6 Malay adults lost 2 or more lines of PVA during the 6 years of the study; this loss was associated with a sizable deterioration in VSF. Loss of VSF was greater in participants with new onset VI compared with those whose existing VI worsened. In older adults, strategies to prevent the onset of new VI may have more relative effect than delaying further progression among those with existing VI.

PMID- 27711914 TI - Second Malignant Neoplasms and Cause of Death in Patients With Germ Cell Cancer: A Danish Nationwide Cohort Study. AB - Importance: Patients given systemic treatment for testicular germ cell cancer (GCC) are at increased risk for a second malignant neoplasm (SMN). Previous studies on SMN and causes of death lacked information on the exact treatment applied or were based on patients receiving former treatment options. Objective: To evaluate the treatment-specific risks for SMN and death in a nationwide population-based cohort of patients with GCC treated with current standard regimens. Design, Setting, and Participants: This study examined a Danish nationwide cohort of 5190 men with GCC who entered the Danish Testicular Cancer database between January 1, 1984, and December 31, 2007. Treatment results were compared with a randomly sampled, age-stratified, population-based control group. Cases of gonadal and extragonadal primary were included in the nationwide cohort. The treatments were surveillance only; retroperitoneal radiotherapy (RT); bleomycin, etoposide, and cisplatin (BEP); or more than 1 line of treatment (MTOL). Main Outcomes and Measures: Cumulative incidence and hazard ratios (HRs) for SMN and death calculated by the Cox proportional hazards model were compared with those of age-matched controls. Results: The study population comprised 2804 patients with seminoma and 2386 with nonseminoma. The median follow-up was 14.4 years (interquartile range, 8.6-20.5 years). The 20-year cumulative incidence of SMN with death as a competing risk was 7.8% (surveillance), 7.6% (BEP), 13.5% (RT), 9.2% (MTOL), and 7.0% (controls). We found no increased risk for SMN after surveillance, while the HRs were 1.7 (95% CI, 1.4-2.0), 1.8 (95% CI, 1.5-2.3), and 3.7 (95% CI, 2.5-5.5), respectively, after BEP, RT, and MTOL. Mortality owing to non-GCC causes was decreased after surveillance, but increased by 1.3 times after BEP and RT and by 2.6 times after MTOL. Excess mortality due to SMN was found after BEP (HR, 1.6; 95% CI, 1.2-2.2), RT (HR, 2.1; 95% CI, 1.5-2.9), and MTOL (HR, 5.8; 95% CI, 3.6-9.6). Conclusions and Relevance: We found no increased risk for SMN or death among patients undergoing surveillance only. The risks for SMN and death due to SMN were increased after BEP alone, RT alone, and MTOL. Approaches to define patients who might benefit from less intensive treatment are needed. PMID- 27711916 TI - Intimacy, Body Image, and Cancer. PMID- 27711915 TI - Palatal Motion After Primary and Secondary Furlow Palatoplasty. AB - Importance: Indications for Furlow palatoplasty include primary repair of cleft palate as well as secondary repair, or secondary palatoplasty for treatment of velopharyngeal insufficiency. Speculation exists surrounding the benefit of secondary Furlow palatoplasty in cases of a previously well-reconstructed palate or a short but otherwise anatomically normal soft palate because it has been theorized that reorientation of a previously reconstructed or normal muscular levator sling should in fact worsen palatal motion. Objective: To compare palatal motion following primary and secondary Furlow palatoplasty using footage from postoperative nasopharyngoscopy videos. Design, Setting, and Participants: In this retrospective case series, medical records in a database of an urban academic pediatric otolaryngology practice was used to identify patients who had undergone either primary or secondary Furlow palatoplasty. Subjects with adequate postoperative nasopharyngoscopy footage were randomized, and 2 blinded reviewers assessed soft palate motion in each video using an abbreviated version of the Golding-Kushner scale. Main Outcomes and Measures: Reviewers' blinded ratings of soft palate motion were quantified using a modified Golding-Kushner scale to generate a mean palatal motion score for each subject (range, 0.0-2.0). Scores of primary and secondary Furlow palatoplasty patients were compared. Results: Over a 4-year period, 20 patients with adequate postoperative nasopharyngoscopy footage were identified (12 primary Furlow palatoplasty patients and 8 secondary Furlow palatoplasty patients). Patients consisted of 8 males and 12 females and ranged in age from 12 months to 22 years at the time of postoperative nasopharyngoscopy. Modified Golding-Kushner scores were similar between groups: mean primary group, 1.61 (range, 0.5-2.0); mean secondary group, 1.53 (range, 0.75-2.0); absolute difference in mean, 0.08 (95% CI, 0.00-0.43); effect size, Hedges g, 0.18. There was fair interrater reliability (interclass coefficient, R = 0.45), consistent with prior reports using this scale. No significant difference in postoperative palatal motion scores was identified between primary and secondary palatoplasty groups in this study. Conclusions and Relevance: When examined in isolation, postoperative motion of the soft palate appears similar following both primary and secondary Furlow palatoplasty procedures, suggesting that there are no major deleterious effects on palatal motion following secondary Furlow palatoplasty. PMID- 27711917 TI - Advances in 3-Dimensional Printing in Otolaryngology: A Review. AB - Importance: Three-dimensional (3-D) printing is an exponentially growing technology that enables the use of a patient's image data to create patient specific models, devices, and implants. Three-dimensional printing, developed in the 1980s, has emerged in the past decade with the potential to create new paradigms in personalized medicine. Observations: The field of otolaryngology has advanced many current and evolving future medical applications of 3-D printing. The predominant uses of 3-D printing have rapidly progressed from patient specific models and simulators to intraoperative guides. Continued advancements now include 3-D-printed implants and future tissue-engineered constructs, which bring new regulatory challenges. This review summarizes the literature and provides a comprehensive guide to the background, applications, and current limitations of 3-D printing across the head and neck. Conclusions and Relevance: Three-dimensional printing enables the rapid production of patient-specific devices for personalized medicine. The field of otolaryngology has pioneered many of the underlying advancements in medical 3-D printing and will continue to remain at the forefront of 3-D printing technology. PMID- 27711918 TI - Anti-Vascular Endothelial Growth Factor Comparative Effectiveness Trial for Diabetic Macular Edema: Additional Efficacy Post Hoc Analyses of a Randomized Clinical Trial. AB - Importance: Post hoc analyses from the Diabetic Retinopathy Clinical Research Network randomized clinical trial comparing aflibercept, bevacizumab, and ranibizumab for diabetic macular edema (DME) might influence interpretation of study results. Objective: To provide additional outcomes comparing 3 anti vascular endothelial growth factor (VEGF) agents for DME. Design, Setting, and Participants: Post hoc analyses performed from May 3, 2016, to June 21, 2016, of a randomized clinical trial performed from August 22, 2012, to September 23, 2015, of 660 participants comparing 3 anti-VEGF treatments in eyes with center involved DME causing vision impairment. Exposures: Randomization to intravitreous aflibercept (2.0 mg), bevacizumab (1.25 mg), or ranibizumab (0.3 mg) administered up to monthly based on a structured retreatment regimen. Focal/grid laser treatment was added after 6 months for the treatment of persistent DME. Main Outcomes and Measures: Change in visual acuity (VA) area under the curve and change in central subfield thickness (CST) within subgroups based on whether an eye received laser treatment for DME during the study. Results: Post hoc analyses were performed for 660 participants (mean [SD] age, 61 [10] years; 47% female, 65% white, 16% black or African American, 16% Hispanic, and 3% other). For eyes with an initial VA of 20/50 or worse, VA improvement was greater with aflibercept than the other agents at 1 year but superior only to bevacizumab at 2 years. Mean (SD) letter change in VA over 2 years (area under curve) was greater with aflibercept (+17.1 [9.7]) than with bevacizumab (+12.1 [9.4]; 95% CI, +1.6 to +7.3; P < .001) or ranibizumab (+13.6 [8.5]; 95% CI, +0.7 to +6.0; P = .009). When VA was 20/50 or worse at baseline, bevacizumab reduced CST less than the other agents at 1 year, but at 2 years the differences had diminished. In subgroups stratified by baseline VA, anti-VEGF agent, and whether focal/grid laser treatment was performed for DME, the only participants to have a substantial reduction in mean CST between 1 and 2 years were those with a baseline VA of 20/50 or worse receiving bevacizumab and laser treatment (mean [SD], -55 [108] um; 95% CI, -82 to -28 um; P < .001). Conclusions and Relevance: Although post hoc analyses should be viewed with caution given the potential for bias, in eyes with a VA of 20/50 or worse, aflibercept has the greatest improvement in VA over 2 years. Focal/grid laser treatment, ceiling and floor effects, or both may account for mean thickness reductions noted only in bevacizumab-treated eyes between 1 and 2 years.

PMID- 27711920 TI - Association of Adjuvant Tamoxifen and Aromatase Inhibitor Therapy With Contralateral Breast Cancer Risk Among US Women With Breast Cancer in a General Community Setting. AB - Importance: Within 10 years after breast cancer diagnosis, roughly 5% of patients develop contralateral breast cancer (CBC). Randomized trials have found that therapy including tamoxifen citrate and aromatase inhibitors (AIs) reduces CBC risk. But little is known about the magnitude and duration of protective associations within the context of real-world clinical management settings, where varying durations of and gaps in treatment are common. Objective: To determine the association between adjuvant tamoxifen and AI therapy and CBC risk within a general community setting. Design, Setting, and Participants: A retrospective cohort study of CBC risk among 7541 patients diagnosed with a first primary unilateral invasive breast cancer at Kaiser Permanente Institute for Health Research (Colorado) or Kaiser Permanente Northwest Center for Health Research (Oregon) between January 1, 1990, and December 31, 2008. Data were analyzed from 1 year after diagnosis of the first breast cancer through the earliest of the following events: CBC diagnosis, other second cancer diagnosis, death, last tumor registry follow-up, exit from the Kaiser Permanente health care plan, or end of study follow-up (December 31, 2010, for Oregon and December 31, 2011, for Colorado). Exposures: Adjuvant tamoxifen use and AI therapy were treated as time dependent exposures, assessed using electronic prescription records. Main Outcomes and Measures: Incident CBC based on long-term systematic follow-up. Results: Among 7541 women with invasive breast cancer, median age at initial breast cancer diagnosis was 60.6 years (age range, 24.9-84.9 years). Women were predominantly (92.9% [7009 of 7541]) of white race. During a median of 6.3 years (range, 1-20.9 years) of follow-up, 248 women developed CBC (45 in situ and 203 invasive). Contralateral breast cancer risk decreased significantly with increasing tamoxifen therapy duration. In current users, the relative risk (RR) per year of tamoxifen use was 0.76 (95% CI, 0.64-0.89), with an estimated 66% (RR, 0.34; 95% CI, 0.29-0.40) RR reduction for 4 years of use compared with nonusers. Risk reductions were slightly smaller for past users but were still significant at least 5 years after stopping tamoxifen therapy (RR per year of use, 0.85; 95% CI, 0.71-0.995). In addition, AI use without tamoxifen therapy was associated with reduced CBC risk (RR for AI users compared with nonusers, 0.48; 95% CI, 0.22-0.97). Risk reductions were most apparent among women whose primary and CBCs were estrogen receptor positive. Conclusions and Relevance: Tamoxifen therapy was associated with reduced CBC risk during treatment and after its cessation, with risk progressively decreasing as tamoxifen therapy duration increased. Among those surviving at least 5 years, tamoxifen use for at least 4 years was estimated to prevent 3 CBCs per 100 women by 10 years after an estrogen receptor-positive first breast cancer, an absolute risk reduction that is consistent with findings from clinical trials. If adjuvant endocrine therapy is indicated for breast cancer treatment, these findings in concert with trial data suggest that women should be encouraged to complete the full course.

PMID- 27711922 TI - Sociodemographic Factors Associated With Knowledge and Risk Perception of Human Papillomavirus and Human Papillomavirus-Associated Oropharyngeal Squamous Cell Carcinoma Among a Predominantly Black Population. AB - Importance: The incidence of human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is increasing in the United States and may be underestimated among black individuals. Characterizing the current knowledge level among black individuals is critical to developing interventions to increase awareness. Objective: To describe the sociodemographic correlates of knowledge and risk perception of HPV and HPV-associated OPSCC among a predominantly black population. Design, Setting, and Participants: A cross-sectional survey was conducted at a drag racing event on September 12 and 13, 2015, in Madison, Illinois. The setting was a community-based oral head and neck cancer screening and education initiative. Participants were 301 drag race attendees 18 years or older who were conveniently sampled from attendees at an annual drag racing event predominantly patronized by black individuals. Main Outcomes and Measures: The primary outcome was knowledge and risk perception of HPV and HPV-associated OPSCC. An electronic-based questionnaire elicited sociodemographic information and contained oral cancer knowledge and risk perception items, which were combined to form knowledge and risk perception scores. Multivariable linear regression analysis assessed estimates of knowledge and risk perception of HPV and HPV-associated OPSCC. Results: Of the 301 participants (111 female and 190 male) completing the questionnaire, 194 (64.5%) were black. Overall, respondents ranged in age from 18 to 78 years, with a mean (SD) age of 48.0 (13.0) years. The mean (SD) knowledge score was 5.7 (4.6) of 15, and the mean (SD) risk perception score was 2.2 (1.4) of 6. Using multivariable linear regression, we found that, for every 1-year increase in age, knowledge of HPV-associated OPSCC decreased by 5.0% and was worse in men (beta = -1.26; 95% CI, -2.33 to -0.18), black vs white individuals (beta = -1.29; 95% CI, -2.35 to -0.23), and those with a high school diploma or less vs college graduates (beta = -3.23; 95% CI, -4.67 to -1.80). Black individuals also had lower perceived risk of developing HPV-associated OPSCC (beta = -0.36; 95% CI, -0.69 to -0.02) compared with white individuals, and participants with a high school diploma or less had lower perceived risk of developing HPV-associated OPSCC compared with those with a college degree or higher (beta = -0.59; 95% CI, -1.04 to -0.14). Conclusions and Relevance: Age and sex were independent correlates of knowledge of HPV-associated OPSCC, while race and education level were correlates of both knowledge and risk perception of HPV associated OPSCC. These findings should inform future interventions targeted at increasing knowledge of HPV-associated OPSCC in black communities.

AB - Importance: To our knowledge, yield strength testing in human nasal septal cartilage has not been reported to date. An understanding of the basic mechanics of the nasal septum may help surgeons decide how much of an L-strut to preserve and how much grafting is needed. Objectives: To determine the factors correlated with yield strength of the cartilaginous nasal septum and to explore the association between L-strut width and thickness in determining yield strength. Design, Setting, and Participants: In an anatomy laboratory, yield strength of rectangular pieces of fresh cadaver nasal septal cartilage was measured, and regression was performed to identify the factors correlated with yield strength. To measure yield strength in L-shaped models, 4 bonded paper L-struts models were constructed for every possible combination of the width and thickness, for a total of 240 models. Mathematical modeling using the resultant data with trend lines and surface fitting was performed to quantify the associations among L strut width, thickness, and yield strength. The study dates were November 1, 2015, to April 1, 2016. Main Outcomes and Measures: The factors correlated with nasal cartilage yield strength and the associations among L-strut width, thickness, and yield strength in L-shaped models. Results: Among 95 cartilage pieces from 12 human cadavers (mean [SD] age, 67.7 [12.6] years) and 240 constructed L-strut models, L-strut thickness was the only factor correlated with nasal septal cartilage yield strength (coefficient for thickness, 5.54; 95% CI, 4.08-7.00; P < .001), with an adjusted R2 correlation coefficient of 0.37. The mean (SD) yield strength R2 varied with L-strut thickness exponentially (0.93 [0.06]) for set widths, and it varied with L-strut width linearly (0.82 [0.11]) or logarithmically (0.85 [0.17]) for set thicknesses. A 3-dimensional surface model of yield strength with L-strut width and thickness as variables was created using a 2-dimensional gaussian function (adjusted R2 = 0.94). Estimated yield strengths were generated from the model to allow determination of the desired yield strength with different permutations of L-strut width and thickness. Conclusions and Relevance: In this study of human cadaver nasal septal cartilage, L-strut thickness was significantly associated with yield strength. In a bonded paper L-strut model, L-strut thickness had a more important role in determining yield strength than L-strut width. Surgeons should consider the thickness of potential L-struts when determining the amount of cartilaginous septum to harvest and graft. Level of Evidence: NA.

AB - Importance: Although mostly asymptomatic, patients with choroidal nevi carry a moderate risk for malignant transformation and visual loss. A novel noninvasive imaging assessment could change the current clinical evaluation of choroidal nevi. Observation: Three patients with a recent diagnosis of choroidal nevi underwent a novel adaptive optical assessment that detected potential photoreceptor abnormalities in the retina overlying the choroidal nevi. Conclusions and Relevance: Adaptive optics imaging may provide high-resolution en face images of retinal structural changes in the photoreceptor mosaic overlying the choroidal nevi. Cone attenuation may be an important component of structural damage in choroidal nevi and may correlate and possibly predict functional visual loss.

AB - The purpose of the current study was to use grounded theory to explore the experiences of caring for pets from the perspective of Taiwanese community dwelling older adults. Twelve participants ages 65 to 73 were interviewed. Data were analyzed using the constant comparative method of qualitative analysis. Pets as an integral part of the family unit and beyond was the core category. The pet becomes part of my family was identified as the antecedent condition; this process undertakes action and interaction among the categories of the pet is part of my daily life, the pet provides positive life energy, and the pet is a sweet companion. Older adults believe caring for pets can bring them self-affirmation and lead them to blessings and luck. The results provide a framework to understand the experiences of older adults who reside with their pets, and serve as a guide for the design of animal-assisted therapy in future research and practice.

AB - In recent years, 1,200 long-term care facility (LTCF) beds have been closed in Ireland, resulting in residents being transferred between facilities. The current study examined morbidity and mortality in residents relocated between LTCFs. The outcomes were studied for residents who transferred between LTCFs compared to residents who did not move (i.e., controls). A retrospective analysis was performed recording demographic data and markers of function and frailty. As a measure of morbidity, new antidepressant medication prescriptions and antibiotic drug use were examined. Mortality at 30 and 90 days was recorded. In total, 76 transferred residents and 62 control residents were studied. Both groups were highly dependent and had a high 90-day mortality rate (18.4% versus 17.7%). Higher prescription rates of antibiotic drugs occurred among relocated residents prior to transfer (59.2% versus 27.4%, p = 0.017). Residents who transferred had a greater number of new antidepressant medication prescriptions than control residents (19.7% versus 8.1%, p = 0.05). Proper planning and vigilance by staff are essential to minimize any distress caused to residents during times of relocation. [Journal of Gerontological Nursing, 42(11), 34-38.]. PMID- 27711931 TI - Managing Challenging Behaviors of Dementia in Veterans: Identifying and Changing Activators and Consequences Using STAR-VA. AB - One of the most challenging clinical issues for long-term care staff is the management of dementia-related behavioral symptoms. STAR-VA is an interdisciplinary intervention for managing challenging behaviors of Veterans with dementia in Community Living Centers (CLCs) within the U.S. Department of Veterans Affairs. The goals of the current article are to delineate categories of challenging behaviors found in CLCs, the context in which behaviors occurred, and the interventions used by CLC clinical teams when implementing STAR-VA. In 2013, 17 CLC teams completed STAR-VA training, enrolling 71 Veteran participants. Four independent raters identified common assessment and intervention themes for six behavior categories, coding activators, consequences, goal behaviors, and care plans for each category. Successful care plans included staff changes in communication approaches, incorporation of pleasant events into care, and individualized environmental modifications. Findings illustrate the range of interventions that CLC teams may apply as a result of systematic behavioral assessment informing an understanding of activators and consequences of dementia related behaviors.

PMID- 27711932 TI - Behavioral Symptoms of Dementia that Present Management Difficulties in Nursing Homes: Staff Perceptions and Their Concordance With Informant Scales. AB - The current study aimed to profile behaviors associated with dementia that pose management difficulties for staff and determine whether existing rating scales capture these reported behaviors. Staff in 17 nursing homes described the behavioral symptoms of 229 residents with predominantly moderate-severe dementia associated with management difficulties. Behaviors were categorized by an expert clinical panel and compared to items in four dementia behavior rating scales. Staff reported 59 discrete behavioral symptoms, with physically agitated, aggressive verbal, non-aggressive verbal, and aggressive physical behaviors most common, followed by resistance to care and inappropriate social and sexual behaviors. Results suggested that some scales omit important behaviors reported by staff for residents with particularly challenging behaviors. The current study highlights the clinical complexity faced by nursing home staff in managing residents with behavioral symptoms of dementia. [Journal of Gerontological Nursing, 43(1), 34-43.]. PMID- 27711934 TI - Relevant areas of functioning in patients with adolescent idiopathic scoliosis on the International Classification of Functioning, Disability and Health: The patients' perspective. AB - OBJECTIVE: To investigate relevant aspects of functioning and disability, and environmental factors in people with adolescent idiopathic scoliosis according to patients' self-reports based on the International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY). DESIGN: Multicentre, empirical, cross-sectional study. SETTING: Four departments of orthopaedics in 4 hospitals, and 5 departments of rehabilitation medicine in 5 hospitals. METHODS: Semi-structured interviews were conducted with 975 patients with adolescent idiopathic scoliosis from 5 hospitals according to the patients' self-reporting. In addition, patients were divided into 3 groups according to clinical outcome. Participant information included demographic and disease-related characteristics. Three adolescent idiopathic scoliosis groups were then compared with respect to the problems identified. Interviews were transcribed verbatim. Categories identified by qualitative analysis were subsequently mapped to the ICF-CY using established linking rules. In order to enrich these findings, we also translated the Scoliosis Research Society 22 Patient Questionnaire (SRS-22 PQ) into the language of the ICF-CY, based on ICF linking rules. RESULTS: A total of 1278 themes that linked to 54 ICF-CY cate-gories from 18 chapters were identified. Twenty-two (41%) categories were identified as Body Functions, 7 (13%) as Body Structures, 15 (27%) as Activities and Participation, and 10 (19%) as Environmental Factors. Of the 54 categories, 45 (83%) were second-level, 5 (9%) were third-level, and 4 (7%) were fourth-level. Differences between the SRS-22 PQ results and our findings were observed for several ICF-CY categories. CONCLUSION: Patients with AIS reported activity limitations and participation restrictions combined with impaired body structures and functions. Environmental factors may act as a barrier to, or facilitator of, patient functioning in daily life. The ICF-CY provides a valuable framework for representing the complexity and multifaceted impact of AIS, and for comparing and examining the content of the SRS-22 PQ for AIS in children and adolescents. These results will be used to develop ICF Core Sets for AIS in China. PMID- 27711935 TI - Admission-Based Prevalence of Schizophrenia, Schizoaffective Disorder and Bipolar I Disorder in a Catchment Area in Sinop, Turkey. AB - OBJECTIVE: To provide registry-based prevalence estimates of schizophrenia, schizoaffective, and bipolar I (BPI) disorders in a defined area of Sinop, Turkey. MATERIAL AND METHODS: All patients that presented to primary and secondary health services over three year time (2009-2011) with diagnosis of psychotic disorder (F06.1, F06.2, F10.5, F12.5, F19.5, F20-29, F30-31, F32.3, F33.3, F39 in ICD-10) covering a population of 73,503 aged 15-64 were included via case registry systems. All accessed case records were pooled. Case ascertainment and diagnostic assessment were achieved through structured clinical interview for DSM-IV, phone interview, or farming a best-estimated diagnosis via records on registers. RESULTS: Registries provided 1,410 probable cases. The successful clinical reappraisal rate was 66.8% (n: 955) while, the final diagnoses were determined via phone interview or best-estimate diagnosis in the rest of the cases. Seven hundred twenty seven individuals were diagnosed with DSM IV yielding a prevalence of 9.8 per 1,000 (95% confidence interval [CI]: 8.2 11.5). Registry-based prevalence of schizophrenia, schizoaffective disorder, BPI disorder, and depression with psychotic features were 3.6 (95% CI: 3.0-4.2), 1.1 (95% CI: 0.8-1.4), 2.7 (95% CI: 2.0-3.3), and 1.0 (95% CI: 0.6-1.3) per 1,000, respectively. CONCLUSION: Ten individuals per 1,000 adult persons admit for any disorder with psychotic symptoms. Registry-based prevalence estimates are lower than the lifetime prevalence estimates. However, analyses of administrative data appear to provide information needed for effectively plan and implement psychiatric services. PMID- 27711936 TI - Evaluation of Changes in Anxiety and Depression Symptoms, and Sexual Functions in Patients Receiving Antidepressants: 3 Months-Long Naturalistic Follow-Up Study. AB - OBJECTIVE: The aim of this study was to study the change in sexual functions within 3 months period following the initiation of antidepressant treatment in psychiatry outpatients, and its relationship with the change in anxiety and depression symptoms. MATERIAL AND METHOD: Eighty two patients, who consecutively applied to the psychiatry outpatient clinic and who were prescribed antidepressants, were included in the study. Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, General Assessment of Functioning Scale and Arizona Sexual Experience Questionnaire (ASEC) were administered to the patients at the first interview, then repeated on a monthly basis during 3 months. RESULTS: Fifty seven of the patients (69.50 %) has been diagnosed with sexual dysfunctions prior to the antidepressant treatment. During the third month after the antidepressant treatment, 24 patients in this group (42.11%) showed no impairment in ASEC scores, whereas 33 patients' (57.89%) scores were still at impairment level. Eight patients out of 25 (32%) who weren't diagnosed with sexual dysfunctions prior to the treatment were later diagnosed with sexual dysfunctions. Sexual dysfunctions correlated with patients' level of functioning, separately from anxiety and depression symptoms. RESULTS: Our study results show that the sexual dysfunction rate is quite high in psychiatric patients population. However, sexual dysfunctions rate which can be related to antidepressant treatment is 36%. It would be appropriate for clinicians to determine benefit-loss balance by considering patients' mental syndromes together with sexual functions. PMID- 27711937 TI - IL-4, TGF-?, NF-?B and MPO levels in Patients with Treatment Resistant Schizophrenia. AB - OBJECTIVE: Schizophrenia is a chronic psychotic disorder in which genetics and environmental factors such as infection and the corresponding immune response play a role in the etiopathogenesis. The aim of this study was to compare some immune factors such as nuclear factor-?B (NF-?B) activation, myeloperoxidase (MPO), the anti-inflammatory cytokine interleukin-4 (IL-4), and regulatory cytokine transforming growth factor-? (TGF-?) in schizophrenia patients and an age- and gender-matched control group. METHOD: Plasma levels of IL-4, TGF-?, MPO, and NF-?B activation in 20 subjects with treatment-resistant schizophrenia and 20 age- and gender-matched healthy controls were analyzed. Disease severity was evaluated using the Brief Psychiatric Rating Scale (BPRS). RESULTS: Plasma TGF-? levels were found to be significantly lower and NF-?B to be significantly higher in antipsychotic treatment-resistant schizophrenia patients than in controls in this study. No significant differences were found between the patient and control groups for serum IL-4 and MPO levels. CONCLUSION: The low TGF-? level in treatment-resistant schizophrenia patients in the symptom exacerbation period indicates that there is inadequate Th1/Th2 balance. Large-scale studies are required to investigate whether this is responsible for resistance in schizophrenia. The fact that the increase in NF-?B that we found in treatment resistant schizophrenia patients in this study has also been reported in the first attack in untreated schizophrenia patients in previous studies indicates that NF-?B plays a role in the disorder's physiopathology from the beginning. PMID- 27711938 TI - The Effect of Medical Education on Attitudes Towards Schizophrenia: A Five-Year follow-Up Study. AB - OBJECTIVE: It has been widely acknowledged that the community and health professionals hold negative attitudes toward patients with impaired mental health. This constitutes a major obstacle for those patients in coping with their disease, managing their care, and hence regulating their lives. Although studies carried out in Turkey document the presence of stigma, they provide limited information about the ways for solving this problem. Drawing on the litrature, the present study investigated the effect of medical education on stigmatization. METHOD: During 2008/2009 academic year, 106 freshmen who were majoring in the Medical School at Celal Bayar University volunteered to participate in the present study. Participants have not yet received any theoretical or practical training on psychiatry. At the beginning of the study, they were informed about the purpose of the study and accordingly requested to fill a consent form. The 32 item schizophrenia subscale of the Attitude Questionnaire developed by Psychiatric Investigations and Education Center (PAREM) was administered to the participants. Along with the questionnaire, they were also requested demographic information. After 5 years, the participants who completed their psychiatry internship were reassessed with the same instrument. RESULTS: 106 volunteers participated in the present study. The majority of the participants were females (54.7%) with equal balance of income and expidentures (65.1%) having a mental disease percentage of 5.6%. Findings showed that students' attitudes towards schizophrenic patients changed significantly positive as they proceed from first year to the fifth year. Results demonstrated that as students move through the years they report more positive attitudes in the areas of etiology of schizophrenia (p<0.01), treatment options (p<0.01), approach to schizophrenic patients (p<0.01), and social interactions (p<0.01). CONCLUSION: We claim that the development of positive attitudes should be integrated in to the mental health curriculum not only in particular years but also throughout the whole years of education. Along this continuum, we believe that students would become more aware of the needs of the schizophrenic patients and gain an on going intuition toward the difficulties that the patients encounter. Viewed together, at the stage of acquiring medical/psychological skills students should be given the opportunity to have direct contact with patients in order to give adequate response to patients' needs and thus observe the improvement at the end of the treatment. PMID- 27711939 TI - The Ege Agraphia Test Battery for Identifying the Writing Disorders in Cases with Mild Cognitive Impairment and Alzheimer's Disease. AB - OBJECTIVE: The purpose of this study is to create an agraphia test battery specific to Turkish language, to obtain normative data for the performance and error types of this test and to demonstrate its success in detecting cognitive disorders in mild cognitive impairment (MCI) cases that can't be diagnosed by formal neuropsychological tests due to the fact that writing is a complex function. METHOD: For this purpose, 20 healthy control (HC) subjects, 20 MCI cases and 20 Alzheimer's disease (AD) patients with Clinical Dementia Rating (CDR) of 1 were evaluated with Ege Agraphia Test Battery. RESULTS: Significant differences between the performance points and the error types of HC subjects, MCI cases and AD patients were obtained. As the cognitive impairment of the subjects in the study got worse, the writing skills also became worse revealing lower test points. Besides, some statistically significant differences between the error types of MCI cases and AD patients were found. CONCLUSION: Ege Agraphia Test Battery is not only a practical test, but also is the first defined agraphia test specific for Turkish language. Writing disorders in cases with MCI support the view that MCI is a transition period for AD. Further studies are required to increase the test data and proper rearrangements of the test battery. PMID- 27711940 TI - Construct Validity of Auditory Verbal Learning Test. AB - OBJECTIVE: Auditory Verbal Learning Test (AVLT) is frequently used in neuropsychology literature to comprehensively assess the memory. The test measures verbal learning as immediate and delayed free recall, recognition, and retroactive and proactive interference. Adaptation of AVLT to the Turkish society has been completed, whereas research and development studies are still underway. The purpose of the present study is to investigate the construct validity of the test in order to contribute to the research and development process. METHOD: In line with this purpose, the research data were obtained from 78 healthy participants aged between 20 and 69. The exclusion criteria included neurological and/or psychiatric disorders as well as untreated auditory/visual disorders. AVLT was administered to participants individually by two trained psychologists. RESULTS: Principal component analysis that is used to investigate the components represented by the AVLT scores consisted of learning, free recall and recognition, in line with the construct of the test. Distractors were also added to these two components in structural equation model. Analyses were carried out on descriptive level to establish the relatioships between age, education, gender and AVLT scores. CONCLUSION: These findings, which are consistent with the literature indicating that memory is affected by the developmental process, suggest that learning/free recall, recognition, and distractor scores of the AVLT demonstrate a component pattern consistent with theoretical knowledge. This conclusion suggests that AVLT is a valid measurement test for the Turkish society. PMID- 27711941 TI - Understanding Treatment Response and Resistance in Obsessive Compulsive Disorder in the Context of Cognitive Neuropsychological Model. AB - Cognitive-behavioral therapies (CBT), antidepressants and neuromodulation techniques are current treatment options used in various stages of treatment procedure for obsessive-compulsive disorder (OCD). The factors that disparate treatment options from psychological approaches to invasive surgical techniques in a psychiatric disorder have in common have scarcely been described in the relevant literature. Cognitive neuropsychological model (CNM) as a novel approach offers a common framework in which psychological and neurobiological models of different psychopathologies are reconciled by means of impaired emotional processing. In this paper, an integrated approach of disrupted top-down and bottom-up emotional processing has been described to understand the efficacy of the different treatment modalities for OCD. In this model, the cognitive therapy is proposed to contribute to the gradual breakdown of schemata through the effect on top-down emotional processing instead of acting on information processing biases directly. Antidepressant drugs and behavioral therapy are proposed to alter the brain's emotion processing in a bottom-up process. Resistance to pharmacotherapy and CBT is a common problem in the patients with OCD, and a lot of factors have been described as negative predictors of these treatment options. The severity of symptoms, presence of specific symptoms, poorer insight, high level of dissociation and family accommodation are the factors associated with resistance to both pharmacotherapy and CBT. The underlying reasons establishing an association between the presence of these diverse factors and treatment resistance were discussed in the context of CNM. PMID- 27711942 TI - Reversible Valproic Acid-Induced Parkinsonism and Cognitive Impairment in an Elderly Patient With Bipolar Disorder I. AB - Valproic acid (VPA) is approved by the Food and Drug Administration (FDA) for the treatment of manic or mixed episodes associated with bipolar disorder. VPA is also used off-label to treat other conditions in psychiatry such as impulse control disorders, major depression, and posttraumatic stress disorder (PTSD). Although VPA is mostly well-tolerated, common adverse effects include gastrointestinal symptoms (nausea, vomiting, diarrhea), neurological symptoms (sedation, ataxia, tremor), weight gain, and alopecia. Less common adverse effects include VPA-induced parkinsonism and cognitive impairment. We describe a patient who developed parkinsonism and cognitive impairment eight years after starting divalproex sodium for bipolar disorder, type I. Over time, the patient's parkinsonian symptoms progressed, and the motor symptoms were partially responsive to carbidopa/levodopa. Her mild cognitive impairment was, for the most part, stable on donepezil. Rapid discontinuation of divalproex sodium resolved the parkinsonian symptoms as well as the cognitive impairment. A brief review of the literature regarding VPA-induced parkinsonism and cognitive impairment in adults is included. Given the reversible nature and potential severity of VPA induced parkinsonism, improved recognition in psychiatric populations is critical, particularly after extended VPA exposure. To the best of our knowledge there are no reports describing the onset of VPA-induced parkinsonism in psychiatric patients more than eight years after starting VPA. PMID- 27711943 TI - Investigating Connectivity of Orbitomedial Prefrontal Region in a Patient with Traumatic Brain Injury. AB - The majority of the research studying the prefrontal region has focused on gray matter injury. However, recent studies show that damage to white matter also contributes to the development of cognitive impairment after traumatic brain injury (TBI). Through the use of diffusion tensor imaging (DTI), it is now possible to assess the white matter fiber pathways between brain regions. With Diffusion Tensor Tractography (DTT), fibers of interest can be three dimensionally reconstructed and associated measurements can be performed. In this paper, we present the case of an individual that suffered from panic attacks, behavioral changes, auditory hallucinations and disturbing bodily sensations after traumatic brain injury. The patient was evaluated with a detailed clinical and neuropsychological assessment, magnetic resonance imaging (MRI) and DTI. MRI revealed cystic encephalomalasia with a diameter of 3.4 cm in the left orbitomedial frontal region. With DTT, major white matter tracts of the traumatized area were compared with symmetrical tracts in the contralateral side. Streamline count for the right inferior fronto-occipital fasciculus (iFOF) was 54 while no streamlines could be found for the left iFOF. For the left uncinate fasciculus and the left cingulum, streamline counts were significantly lower compared with the right side (62% and 34% lower; respectively). White matter damage in TBI can cause dysfunction of different brain regions through disruption of connections with the traumatized area. In this case report, we emphasized that symptoms were not limited with dysfunction of the traumatized region and the regular functions of other brain regions were also affected via the disturbance of connection pathways.

PMID- 27711945 TI - [Laboratory requirements to diagnose viral hepatitis under the development of guidelines]. AB - Infections with hepatitis B-, C- and D- viruses have a significant health burden. In Germany, the seroprevalence of HBs-Ag is calculated with 0.6 % and of HCV antibodies with 0.3 %. However, most patients are not diagnosed. Sequelae are liver-cirrhosis and hepatocellular carcinoma. Several S3-guidelines for the diagnosis and treatment of viral hepatitis have been established. However, implementation of guidelines is not easy to evaluate. To estimate the changes of medical knowledge and diagnostic procedures about viral hepatitis, 7 parameters of liver-diagnostics were elected to analyze the requirements profile in the years 2005 - 2011 in 4 German federal states. GPT/ALT showed no important change except the influence of the laboratory-reformation. HBs-Ag and HCV-Ab show only a minor increase in adults. The molecular differentiation of HBV-DNA and HCV-RNA showed changes up to 200 % in some regions; however, this might not be explained by more screening but rather increased treatment monitoring or new region specific regulations. The most significant increase was observed for HDV antibodies, but the amount of testing is still at a low level. The development and update of guidelines, the World-Hepatitis-Awareness-Day, and other specific nationwide activities did not result in a major increase in the screening of viral hepatitis with the exception of HDV. The results and the new treatment options against hepatitis C should motivate to continue the education in the field of viral hepatitis in an intensified manor. PMID- 27711946 TI - [Biosimilars in inflammatory bowel disease]. AB - After the expiry date of the patent protection for Infliximab in 2013, the biosimilar CT-P13 was approved for indications in Crohn's disease and ulcerative colitis in adults as well as in children. The approval has been based on two randomized clinical studies indicating equivalence for the biosimilar with regard to pharmacokinetics, efficacy, as well as side-effects. The clinical experience since, in addition to multiple non-randomized studies, indicate a comparable efficacy and immunogenicity of the Infliximab biosimilar CT-P13 in inflammatory bowel disease. Thus, the introduction of the biosimilar as primary therapy seems to be justified. Tight monitoring of the safety of biosimilars with regard to efficacy and side effects has to be ensured. PMID- 27711947 TI - [Opportunities and challenges of extrapolation for biosimilars]. AB - Although biosimilars approved in the European Union have proved to be safe and efficacious, their licensing requirements continue to be disputed by medical professionals. In particular, extrapolation to indications of the originator without one's own clinical data of the biosimilar is controversial. Conceptually, the development of biosimilars is derived from that of generics. However, due to their complexity and inherent variability, considerably more data are necessary for biosimilars to demonstrate comparability with the originator (the reference product) than for the usually low-molecular generics. Biosimilars increase competition and help contain healthcare, and they improve access for patients to valuable treatments with biologicals. However, biosimilar development is a laborious and lengthy process and requires major biotechnological know-how. The basis is comprehensive, structural, and functional characterization of the biosimilar and reference product as well as their comparison with suitable and sensitive methods. The clinical development programme is reduced and tailored to address remaining uncertainties and to confirm comparable clinical performance. Extrapolation of data to other indications of the reference product is the greatest cost advantage of biosimilar development, but must always be scientifically justified and, if necessary, substantiated by further data. The scientific principles underlying the comparability exercise for a biosimilar are the same as those applied to a change in the manufacturing process of an already licensed biological. In both cases, different versions of a biological substance are compared and the clinical relevance of observed differences is assessed. Competent authorities do have decades of experience in evaluating changes in the manufacturing process, which they can now apply to biosimilars. For approval of a biosimilar and extrapolation of data, the totality of the evidence from the complete comparability exercise is considered, as has been the case for the first biosimilar infliximab.

AB - Highly porous metaphyseal cones are used for the management of large bone defects in revision total knee arthroplasty. These cones fill defects and allow bony ongrowth while providing several sizing and offset options. In this case series, we evaluated three patients who received these latest generation metaphyseal cones. Specifically, these cases will be explored in detail with respect to history, indications, operative technique, and short-term outcomes. Overall, these newer generation porous coated cones are excellent options for large contained bone loss in the absence of infection, and they have demonstrated good clinical and radiological outcomes at short-term follow-up. PMID- 27711949 TI - Advanced endoscopic imaging: European Society of Gastrointestinal Endoscopy (ESGE) Technology Review. AB - Background and aim: This technical review is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the utilization of advanced endoscopic imaging in gastrointestinal (GI) endoscopy. Methods: This technical review is based on a systematic literature search to evaluate the evidence supporting the use of advanced endoscopic imaging throughout the GI tract. Technologies considered include narrowed-spectrum endoscopy (narrow band imaging [NBI]; flexible spectral imaging color enhancement [FICE]; i-Scan digital contrast [I-SCAN]), autofluorescence imaging (AFI), and confocal laser endomicroscopy (CLE). The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was adopted to define the strength of recommendation and the quality of evidence. Main recommendations:1. We suggest advanced endoscopic imaging technologies improve mucosal visualization and enhance fine structural and microvascular detail. Expert endoscopic diagnosis may be improved by advanced imaging, but as yet in community-based practice no technology has been shown consistently to be diagnostically superior to current practice with high definition white light. (Low quality evidence.) 2. We recommend the use of validated classification systems to support the use of optical diagnosis with advanced endoscopic imaging in the upper and lower GI tracts (strong recommendation, moderate quality evidence). 3. We suggest that training improves performance in the use of advanced endoscopic imaging techniques and that it is a prerequisite for use in clinical practice. A learning curve exists and training alone does not guarantee sustained high performances in clinical practice. (Weak recommendation, low quality evidence.) Conclusion: Advanced endoscopic imaging can improve mucosal visualization and endoscopic diagnosis; however it requires training and the use of validated classification systems. PMID- 27711950 TI - [Periprosthetic Acetabulum Fractures]. AB - In contrast to periprosthetic fractures of the femur, periprosthetic fractures of the acetabulum are rare complications - both primary fractures and fractures in revision surgery. This topic is largely under-reported in the literature; there are a few case reports and no long term results. Due to an increase in life expectancy, the level of patients' activity and the number of primary joint replacements, one has to expect a rise in periprosthetic complications in general and periprosthetic acetabular fractures in particular. This kind of fracture can be intra-, peri- or postoperative. Intraoperative fractures are especially associated with insertion of cementless press-fit acetabular components or revision surgery. Postoperative periprosthetic fractures of the acetabulum are usually related to osteolysis, for example, due to polyethylene wear. There are also traumatic fractures and fractures missed intraoperatively that lead to some kind of insufficiency fracture. Periprosthetic fractures of the acetabulum are treated conservatively if the implant is stable and the fracture is not dislocated. If surgery is needed, there are many possible different surgical techniques and challenging approaches. That is why periprosthetic fractures of the acetabulum should be treated by experts in pelvic surgery as well as revision arthroplasty and the features specific to the patient, fracture and prosthetic must always be considered. PMID- 27711951 TI - Novel Heterozygous Genetic Variants in Patients with 46,XY Gonadal Dysgenesis. AB - 46,XY gonadal dysgenesis (GD) constitutes a rare group of disorders characterized by the presence of dysfunctional testes in genotypic males. The molecular etiology is not known in about 2 thirds of instances. The aim of this study was to identify the genetic cause in patients with 46,XY gonadal dysgenesis. Based on clinical, cytogenetic, and biochemical screening, 10 patients with 46,XY GD were recruited. Direct sequencing of SRY, NR5A1, SOX9, DAX1, DHH, DMRT1 genes was carried out for molecular analysis. Among 10 patients, 5 were diagnosed with complete gonadal dysgenesis (CGD), 3 with partial gonadal dysgenesis (PGD), and 3 with testicular agenesis. Molecular analysis revealed 12 heterozygous genetic changes, 4 of which were novel. One (c.416T>A) was observed in evolutionary conserved region of DMRT1 gene in a patient with CGD and was found to be probably damaging on in silico analysis. Other 3 were identified in NR5A1 gene (c.990+22 C>A, c.1387+1403T>A and p.131P), but their association with gonadal dysgenesis is not evident from our study. These genetic changes were absent in parents and 50 healthy control samples, which were also studied. With targeted sequencing approach, a molecular diagnosis was made in only one patient with 46,XY GD. The application of new genomic technologies is required for the precise evaluation of these rare genetic defects. PMID- 27711952 TI - Are Thyroid Hormone Values Obtained in Hospitalized Elderly Patients Reproducible? - A Cohort Study. AB - It is unclear whether TSH should be obtained in elderly hospitalized patients as several factors associated with hospitalization influence these levels, which may not truly represent the thyroid status of the individual. All patients>=65 years old hospitalized in a geriatric ward in the years 2012-2014 had TSH measured irrespective of the cause for hospitalization. All patients in whom TSH levels were performed in an ambulatory setting 2-12 months following hospitalization were identified and these TSH levels were correlated with levels recorded during hospitalization. Factors influencing TSH reproducibility were identified through review of patients' medical records. Of 562 patients hospitalized during the study period, 198 had repeat ambulatory TSH measurements during follow-up. The Katz Index of Independence was higher (9.43+/-2.98 vs. 8.43+/-3.67 p=0.002) and cerebrovascular disease was less prevalent (15.6 vs. 25.2% p=0.014) in those who had a repeat TSH measurement compared with those who did not, but other baseline characteristics and TSH levels on admission were similar. Ambulatory TSH values were significantly correlated with those obtained during hospitalization (correlation coefficient=0.677), irrespective of baseline systolic blood pressure, cause of hospitalization, or admission albumin levels. Mean TSH difference between in-hospital and ambulatory was 0.65+/-2.36 mIU/l and in more than 94% of cases TSH values differed by less than 2 mIU/l between the 2 measurements. In hospitalized patients>=65 years old, TSH levels are highly concordant with ambulatory values. TSH obtained during hospitalization may be used for making treatment decisions and has clinical utility in this population. PMID- 27711953 TI - [Safety of Hyaluronic Acid in Postoperative Treatment after Penetrating Keratoplasty]. AB - BACKGROUND: The objective of this clinical trial was to confirm the safety of phosphate-free high molecular weight hyaluronate (HYLO(r)-GEL) as lubricant for postoperative care after penetrating keratoplasty. PATIENTS AND METHODS: 51 eyes were followed up 6 weeks after penetrating keratoplasty under therapy with phosphate-free high molecular weight hyaluronate. Visual acuity, intraocular pressure, conjunctival hyperaemia, conjunctival chemosis, corneal fluorescein staining, corneal infiltrates, corneal endothelial-epithelial decompensation, Descemet's folds, Tyndall effect, cells in the anterior chamber and subjective assessment of lacrimation, foreign body sensation, pressure sensation, burning, mucus and itching were recorded on the first, third and fifth postoperative days and six weeks postoperatively. Tolerance was rated by the patient and the attending ophthalmologist. RESULTS: The following objective parameters improved significantly from day 1 to week 6 in patients treated with phosphate-free high molecular weight hyaluronate: visual acuity, conjunctival hyperaemia, conjunctival chemosis, corneal fluorescein-staining, corneal endothelial epithelial decompensation, Descemet's folds, the maximum diameter of corneal erosion, Tyndall effect and cells in the anterior chamber. In addition, there was significant improvement in the course of the following subjective complaints: lacrimation, foreign body sensation, pressure sensation and itching. In total 63 % (32/47) of the study patients reported excellent local tolerance of phosphate free high molecular weight hyaluronate on day one postoperatively. This proportion rose to 86 % (37/43) 6 weeks postoperatively. The safety of phosphate free high molecular weight hyaluronate was rated by the ophthalmologists as "perfect" in 92 %, as "acceptable" in 6 % and as "unacceptable" in 2 % of eyes. CONCLUSION: Therapy with phosphate-free high molecular weight hyaluronate results in significant improvements in objective findings and subjective symptoms after penetrating keratoplasty. Tolerance was rated as "excellent" by the ophthalmologist in 92 % of patients in the early postoperative follow-up. PMID- 27711954 TI - [Imagery Rescripting and Psychophysical Relations Based on the ImRs-Therapy Concept Used for Test Anxiety: Review and First Experience]. AB - Imagery Rescripting (ImRs) is an emotion-focused treatment technique, which was developed for persons suffering from traumatic experiences. ImRs includes imaginary exposure and rescripting alongside cognitive re-structuring. The principle of ImRs is based on the activation of emotions and the structuring of dysfunctional affective-cognitive schemata. ImRs is an effective treatment for PTSD and could be adapted to suit other psychological disorders. The current state of research focuses primarily on the wide range of uses. To date, physiological processes during the imagery rescripting have not been explored. Because of this, together with the cooperation of colleagues at Bar-Ilan University in Israel, we have conducted a pilot study to investigate psychophysiological patterns during ImRS sessions. Specifically, we examine the effectiveness of a targeted 6-session protocol developed for the treatment of test anxiety on a student sample, during which we monitor the sympathetic response of both clients and therapists. First feedback from the participants supports the power of imagery. PMID- 27711955 TI - [Validation of a German-language Version of the Body Checking Questionnaire (BCQ) in Adolescents with Anorexia and Bulimia Nervosa]. AB - Body-related checking behavior, as a behavioral manifestation of a disturbed body image, fosters the development and maintenance of eating disorders. The Body Checking Questionnaire (BCQ) is the most commonly used questionnaire for measuring body-related checking behavior internationally. To date, validation studies are only available for adult populations. Therefore, the aim of this study was to statistically test the German-language version of the BCQ in adolescents. A total of N=129 female adolescents were examined, comprising n=57 with Anorexia Nervosa, n=24 with Bulimia Nervosa, and n=48 healthy female adolescents. A confirmatory factor analysis supports the subdivision of the BCQ into a general factor and the subfactors "overall appearance", "specific body parts" and "idiosyncratic checking", which was also found in the original version. The internal consistencies are good (alpha>=0.81), and the BCQ is able to differentiate well between adolescents with and without eating disorders. Significant correlations between the BCQ and other body image questionnaires point to a good convergent validity. The German-language BCQ thus constitutes a valid and reliable instrument for measuring body-related checking behavior among adolescents in clinical research and practice. PMID- 27711956 TI - [Psycho-Oncologic Care by a Consultation-Liaison Service - Differences between Oncologic Patients with and without Psychiatric Comorbidity]. AB - Background: Psycho-oncologic consultation and liaison services (CLS) are mainly psychosomatic oriented teams in acute care hospitals. Their interventions are electively, setting-related or universal like in accredited centers. Objectives: We investigated whether clinical and care-related differences between cancer patients with and without psychiatric comorbidity exist as well as between patients treated in oncologic centers and aside thereof. We also investigated possible differences according to psychiatric as well as to oncologic diagnoses. Method: A 4-year study (2012-15, for center-related comparisons: 2013-15) in a regional hospital (520 beds, 18 wards, 6 oncologic centers) based on data from a basic documentation covering selected clinical as well as care variables. Data was been collected on occasion of each consultation (N=3441 corresponding to 2257 patients). Associations between clinical and care-related variables were identified by means of chi-square, ANOVA, Scheffe post hoc tests as well as by means of multivariate linear and logistic regression models. Results: The sample was on average 64 years old, about 68% women, and they showed a distress about 4.63. Affective disorders were found for 4.4% and adjustment disorders for 7.8% of the sample. Bivariate tests show that patients with psychiatric comorbidity (19%) and patients aside the centers (24%) were highly significant (p<0.001) clinically more impaired and received more intensive care by CLS. Within the centers the psychiatric comorbidity amounted on average 9% (range:4-16%), that was lower than aside the centers (33,5%). Multivariate regression models largely confirm the differences found in bivariate tests; no gender differences were found, but a negative association between age and care density. Discussion: This study supports that psychooncologic CLS follow a good practice, because patients with a higher clinical burden related to psychiatric comorbidity receive more intensive care. Comorbidity quotas found were lower than in other similar German investigations. Conclusions: Oncologic patients with psychiatric comorbidity should be identified by CLS because they have a larger clinical burden and more distress. The fact that older patients receive less face to face interventions may have to be balanced with systemic interventions. Care needs - and not only received care - have to be assessed in further research. PMID- 27711957 TI - Evaluation of Ovarian Reserve with AMH Level in Patients with Well-Differentiated Thyroid Cancer Receiving Radioactive Iodine Ablation Treatment. AB - Introduction: Radioactive iodine (RAI) ablation treatment is used for patients diagnosed with well-differentiated thyroid cancer in order to reduce the risk of recurrence. RAI ablation treatment can adversely affect gonads in males and females. In this study, we aimed to determine ovary damage and infertility risk due to RAI, using serum anti-Mullerian hormone (AMH) level, in females who received RAI ablation treatment. Materials and Methods: 45 female patients who have not gone through the menopause and had received RAI ablation treatment for well-differentiated thyroid cancer in premenopausal period, and 40 healthy females as control groups were included in this study. The serum AMH, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), thyroid stimulating hormone (TSH) and creatinine levels of the patients included in the study were analyzed and compared to those of the control group with similar demographical characteristics. Results: No differences were found between the patient group and control group in terms of age, height, weight, body mass index, LH, E2 and creatinine. The difference in AMH, FSH and TSH between both groups were found to be significant. There was no statistically significant relation between the age and AMH levels. Similarly, no statistically significant relation between RAI exposure duration and AMH levels was determined. When the patients below and above the age of 35 were compared with regard to AMH (2.95+/-1.79 and 2.75+/-1.94, respectively) and FSH (5.45+/-1.63 and 5.99+/-3.06, respectively), the difference between them was found to be statistically insignificant. Oligo/anovulation was detected in 7 patients (15.6% of the patient group) after RAI treatment, 8 (17.8%) patients became pregnant after RAI treatment, and none of the patients, who were actively trying to get pregnant, were unable to achieve it. Conclusion: According to these results, it may be concluded that low AMH levels due to RAI treatment can cause damage to the ovaries of patients; nevertheless, considering the AMH levels and the absence of infertility in the patients, the infertility risk was found to be low. PMID- 27711958 TI - Sexual Functioning and Depressive Symptoms in Women with Diabetes and Prediabetes Receiving Metformin Therapy: A Pilot Study. AB - Aim:Metformin is a drug of choice for the management of type 2 diabetes mellitus. Very little is known about its effect on human sexual function. Methods: The study included 3 age- and weight-matched groups of premenopausal women: individuals with type 2 diabetes, women with prediabetes and healthy controls. All women with diabetes and 50% of those with prediabetes were then treated with metformin and complied with lifestyle modification. The remaining individuals, not receiving pharmacotherapy, only complied with dietary recommendations. Apart from measuring plasma glucose and assessing insulin sensitivity, all enrolled women completed questionnaires evaluating sexual function (Female Sexual Function Index - FSFI) and the presence and severity of depressive symptoms (Beck Depression Inventory-Second Edition - BDI-II) initially and after 6 months. Results: Women with diabetes had a lower total FSFI score, as well as lower scores for all domains: sexual desire, sexual arousal, lubrication, orgasm, sexual satisfaction and dyspareunia, and these scores correlated with a degree of insulin resistance. Women with prediabetes had lower scores for sexual desire and sexual satisfaction. Moreover, women with diabetes and prediabetes were characterized by a higher total BDI-II score. Metformin treatment not only normalized sexual desire and sexual satisfaction in both studied groups, but also normalized or improved the remaining domains of FSFI in patients with diabetes, and these effects correlated with an improvement in insulin resistance. Conclusions: Metformin treatment provides a beneficial effect on female sexual function and the strength of this effect depends on the degree of insulin resistance. PMID- 27711959 TI - Novel Approaches for the Treatment of Familial Hypercholesterolemia. AB - Familial hypercholesterolemia (FH) is an autosomal disorder characterized by increased levels of total cholesterol and low density lipoprotein (LDL) cholesterol.The extent of underdiagnosis and undertreatment of individuals with FH is largely unknown.The LDL-lowering capacity of statins in combination with other lipid-lowering drugs is maximally around 50-60%. FH patients have a strongly elevated LDL-C and in most cases maximal current treatment is not sufficient to reach the desired LDL targets.Therefore, FH patients have a large residual cardiovascular risk despite the use of statins and there is a medical need for new additional drugs to further lower LDL-C in patients with FH to improve their prognosis.PCSK9 inhibitors have shown great efficacy in lowering lipids with very few side effects. No synergism between statins and PCSK9 inhibition was observed in many trials, allowing clinicians to select a statin dose before considering the initiation of PCSK9-inhibitor therapy.In patients with FH, who are at risk for markedly accelerated atherosclerosis and premature cardiovascular death, also treatment with lomitapide or mipomersen has the potential to reduce the risk of atherosclerotic cardiovascular disease and premature mortality.These new drugs will be probably reserved for the most severely affected FH patients and could help clinicians to reduce their residual cardiovascular risk.

AB - Coralline algae are conspicuous members of many marine assemblages, especially those characterized by intense grazing pressure. We explored whether articulated species, especially Corallina vancouveriensis, depend on grazing invertebrates to both establish and flourish in an exposed rocky intertidal setting, and whether this plant-grazer relationship varied over more than three orders of magnitude (~100->300,000 MUm). Three experimental manipulations, supplemented by observations on recruitment, demonstrated that (i) C. vancouveriensis failed to recover rapidly from disturbed areas when grazers were experimentally excluded; (ii) recruitment occurred in the presence of grazers; (iii) increasing surface texture of molded surfaces enhanced coralline recruitment more when grazers were present; and (iv) settlement occurred predominately in microtopographical low areas of a molded surface, whereas a competitively superior fleshy red alga tended to recruit to high areas. These results confirm that coralline algal establishment and persistence are enhanced by grazers and reveal that this relationship is consistent over a range of biologically relevant scales. PMID- 27711962 TI - Effects of a diet containing dried grape pomace on blood metabolites and milk composition of dairy cows. AB - BACKGROUND: The effect of a diet containing 15% grape pomace (GP) on the general health status and milk quality of dairy cows was assessed by plasma biochemistry and total polyphenol (TP) content, milk polyphenols, milk composition and milk protein fractions. RESULTS: Among the polyphenols measured by liquid chromatography-mass spectroscopy in GP, in feed containing GP (GP+) or not containing GP (GP-), gallic acid and epicatechin were present in the highest concentrations (67.58 and 19.23 ug mL-1 , respectively). Higher amounts of TP were also detected in the blood plasma of GP+ cows (114.06 and 83.93 mg GAE L-1 , respectively) but not in their milk (233.17 and 245.75 mg GAE L-1 , respectively). Also a significant increase was found for lactose and beta lactoglobulin, although there was no effect on alpha-lactalbumin, albumin, secretory components and caseins. CONCLUSION: Inclusion of 15% GP in the diets of dairy cows is beneficial for overall normal blood constituent metabolism and helps to maintain cow health. The milk of cows fed with a GP diet preserves the normal levels of fat, protein and caseins, and has increased levels of components that make this milk a versatile ingredient material for the food industry (e.g. model whey powders, stability of lactose-rich powders).

AB - OBJECTIVE: To examine the technical feasibility of percutaneous endoscopic pediculectomy using a lateral approach and to evaluate its use for decompression and examination of the thoracic and lumbar spinal canals in small dogs. STUDY DESIGN: Experimental study. ANIMALS: Clinically normal adult dogs (n=10). METHODS: After optimizing the technique in cadavers, percutaneous endoscopic pediculectomy was performed using a lateral approach to the thoracic (T12) or lumbar (L2) vertebrae in 5 dogs each. Using fluoroscopic guidance, a K-wire, dilator, and (cannula) working sleeve were placed. A window for visualizing the spinal cord and floor of the spinal canal was created using a specialized drill, rongeurs, trephine, and elevator. Gait and neurologic status were monitored postoperatively, and computed tomography (CT) and magnetic resonance imaging (MRI) performed. RESULTS: All procedures were completed successfully (T12, 45 +/- 13 minutes; L2, 59 +/- 14 minutes) with clear observation of the spinal cord and floor of the spinal canal. Normal ambulation was maintained in 9 dogs. One dog in the L2 group had ipsilateral hind limb weakness that resolved within 4 days. One dog in the L2 group suffered a fracture of the accessory process. One dog each in the T12 and L2 groups had hyperintense lesions on T2-weighted MRI images, suspicious of focal edema, which reduced at 4 weeks after initial examination, possibly reflecting gliosis. CONCLUSION: Pediculectomy using a percutaneous endoscopic thoracolumbar lateral approach is feasible, provides a good view of the spinal canal, and may be an alternative for treatment of disk disease in dogs. PMID- 27711965 TI - Measuring circulating placental RNAs to non-invasively assess the placental transcriptome and to predict pregnancy complications. AB - Circulating nucleic acids have revolutionized prenatal diagnosis in the last decade, allowing non-invasive screening for single gene or chromosomal defects using a single sample of maternal blood. In addition to DNAs, RNAs from the placenta are released into the maternal blood from early in pregnancy and may reflect changes in gene expression occurring within the placenta. Measuring circulating RNA may therefore provide insights into the placental transcriptome without the need for invasive testing. Combined with advances in next-generation sequencing and molecular analyses, it may be possible to measure circulating RNA to improve our understanding of placental pathology and develop novel non invasive biomarkers for pregnancy complications and monitoring high-risk pregnancies. This review summarizes the current technologies available and the studies that have measured circulating placental RNA to predict and/or monitor pregnancies complicated by preeclampsia, fetal growth restriction, preterm birth, early pregnancy complications, invasive placentation and twin-twin transfusion syndrome. Prospective cohort studies are now required to validate these findings to determine the clinical applicability of measuring circulating placental RNA to develop novel biomarkers for a wide spectrum of pregnancy complications.

AB - Ibandronate (IBN) and pulsed electromagnetic field (PEMF) have each shown positive effects for treating osteoporosis, but no study has evaluated the relative effects of these treatments combined. This study investigated the effects of IBN + PEMF on bone turnover, mineral density, microarchitecture, and biomechanical properties in an ovariectomized (OVX) rat model of osteoporosis. Fifty 3-month-old rats were randomly apportioned to receive a sham-operation (n = 10), or ovariectomy (n = 40). The latter group was equally divided as the model (OVX control) or to receive IBN, PEMF, or IBN + PEMF. Beginning the day after surgery, the IBN and IBN + PEMF groups received weekly subcutaneous IBN; the PEMF and IBN + PEMF groups were given daily PEMF during the same 12 weeks. After 12 weeks of treatments, biochemical parameters, bone mineral density (BMD), microarchitecture parameters, biomechanical properties, and some metabolic modulators that are involved in bone resorption were compared. The L5 lumbar vertebral body BMDs of the IBN, PEMF, and IBN + PEMF groups were 121.6%, 119.5%, and 139.6%; maximum loads were 111.4%, 112.7%, and 121.9%; and energy to failure was 130.8%, 129.2%, and 154.9% of the OVX model, respectively. The IBN + PEMF group had significantly lower levels of serum tartrate-resistant acid phosphatase 5b, and greater improvement in BMD, bone microarchitecture, and strength of the lumbar spine compared with monotherapy groups. Results showed that IBN + PEMF had a more favorable effect on the lumbar spine in this osteoporosis model than did either monotherapy. Bioelectromagnetics. 38:31-40, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27711966 TI - An Argument for Fewer Clinical Trials. AB - The volume of clinical research is increasing exponentially-far beyond our ability to process and absorb the results. Given this situation, it may be beneficial to consider reducing the flow at its source. In what follows, I will motivate and critically evaluate the following proposal: researchers should conduct fewer clinical trials. More specifically, I c onsider whether researchers should be permitted to conduct only clinical research of very high quality and, in turn, whether research ethics committees (RECs) should prohibit all other, lower-quality research, even when it might appear to meet some minimal ethical standard. Following a close analysis of the social-value requirement of ethical clinical research, I argue that this proposal is defensible. The problem identified in this paper has two parts, quantity and quality, and some clarification is needed about the latter because "quality" is a highly contested term in the medical literature. When some scholars advocate for high-quality trials, they mean large-scale, simple, explanatory randomized controlled trials. Others, including myself, have defended a different characterization of high quality research that tends more toward pragmatic trial design and the use of methods other than RCTs. Pragmatic trials aim to provide evidence that directly supports clinical decision-making in "usual" care settings. Unlike explanatory trials, which aim to abstract away from particular settings and patients, in the hopes of creating ideal conditions for the success of an intervention, pragmatic trials deliberately pursue knowledge of high applicability, through the use of representative subjects, clinically important questions, flexible treatment protocols, patient-oriented outcome measures, and so on. I see applicability as a marker of high-quality research. The context in which research is meant to be applied should be the context in which new interventions are evaluated. PMID- 27711967 TI - Augmented Repair of an Achilles Tendon Rupture Using the Flexor Digitorum Lateralis Tendon in a Toy Poodle. AB - OBJECTIVE: To report appositional augmentation of Achilles tendon rupture in a toy breed dog with an intact flexor digitorum lateralis (FDL) muscle tendon. STUDY DESIGN: Clinical case report. ANIMALS: Two-year-old spayed female Toy Poodle with Achilles tendon rupture. METHODS: The Achilles tendon was accidentally ruptured by hair clippers during grooming. The dog demonstrated a plantigrade stance without digital flexion of the right hind limb. The ruptured gastrocnemius and superficial digital flexor tendons were sutured to their respective cut ends using a simple locking loop pattern under a surgical microscope. The repair site was appositionally augmented by the caudally retracted intact FDL. An aluminum splint was applied on the plantar aspect to immobilize the tarsal joint for the first 2 weeks, after which a soft bandage was applied for another 2 weeks. RESULTS: At the 7 month follow-up no lameness was detected during walking and no complications associated with decreased FDL function such as digital contracture were observed. The range of motion of the tarsal joint had improved and could be flexed to ~60 degrees and extended fully. CONCLUSION: Use of the FDL is feasible for augmenting Achilles tendon repair in toy breed dogs.

AB - From 2009 to 2011, freshly harvested processing tomatoes from California commercial fields were surveyed for mold species present in the mature fruit. Molds were recovered from the majority of fruit that had visual symptoms of black mold and other decays and from about a quarter of randomly sampled, asymptomatic fruit. Alternaria, Fusarium, and Geotrichum spp. were the most commonly recovered fungi in both symptomatic and random samples. Based on pairwise statistical analysis, the frequencies of 2 different fungal genera in a composite 11 kg sample were, in general, statistically independent events, with the exception of a weak association between the incidence of Geotrichum with Alternaria, Cladosporium, or Stemphylium. The mold genera distribution data in this study provide the processing tomato industry with a valuable informational resource that can be used in the management of fungal infection in both the crop and in the final thermally processed finished product. Because of the relative abundance of these fungi, this survey supported the development of genera-specific immunochromatographic diagnostic assays to detect and quantify mold occurrence in Californian processing tomatoes as a potential alternative to the current subjective visual methods, which are characterized by imprecision and nonuniform species sensitivity. A simulation of 1 million 11 kg-composite samples based upon the distributional survey data projected that a multiantibody immunochromatographic assay using monoclonal antibodies for Alternaria, Cladosporium, Fusarium, and Geotrichum could successfully detect the presence of mold in 94% of moldy processing tomato samples collected randomly at harvest.

PMID- 27711971 TI - Future warming and acidification effects on anti-fouling and anti-herbivory traits of the brown alga Fucus vesiculosus (Phaeophyceae). AB - Human-induced ocean warming and acidification have received increasing attention over the past decade and are considered to have substantial consequences for a broad range of marine species and their interactions. Understanding how these interactions shift in response to climate change is particularly important with regard to foundation species, such as the brown alga Fucus vesiculosus. This macroalga represents the dominant habitat former on coastal rocky substrata of the Baltic Sea, fulfilling functions essential for the entire benthic community. Its ability to withstand extensive fouling and herbivory regulates the associated community and ecosystem dynamics. This study tested the interactive effects of future warming, acidification, and seasonality on the interactions of a marine macroalga with potential foulers and consumers. F. vesiculosus rockweeds were exposed to different combinations of conditions predicted regionally for the year 2100 (+?5 degrees C, +?700 MUatm CO2 ) using multifactorial long-term experiments in novel outdoor benthic mesocosms ("Benthocosms") over 9-12-week periods in four seasons. Possible shifts in the macroalgal susceptibility to fouling and consumption were tested using consecutive bioassays. Algal susceptibility to fouling and grazing varied substantially among seasons and between treatments. In all seasons, warming predominantly affected anti-fouling and anti-herbivory interactions while acidification had a subtle nonsignificant influence. Interestingly, anti-microfouling activity was highest during winter under warming, while anti-macrofouling and anti-herbivory activities were highest in the summer under warming. These contrasting findings indicate that seasonal changes in anti-fouling and anti-herbivory traits may interact with ocean warming in altering F. vesiculosus community composition in the future. PMID- 27711972 TI - Distinct and shared three-dimensional chromosome organization patterns in lymphocytes, monoclonal gammopathy of undetermined significance and multiple myeloma. AB - The consistent appearance of specific chromosomal translocations in multiple myeloma has suggested that the positioning of chromosomes in the interphase nucleus might play a role in the occurrence of particular chromosomal rearrangements associated with malignant transformation. Using fluorescence in situ hybridization, we have determined the positions of selected chromosome pairs (18 and 19, 9 and 22, 4 and 14, 14 and 16, 11 and 14) in interphase nuclei of myeloma cells compared to normal lymphocytes of treatment-naive patients. All chromosome pairs were arranged in a nonrandom pattern. Chromosomes commonly involved in myeloma-associated translocations (4 and 14, 14 and 16, 11 and 14) were found in close spatial proximity, and this is correlated with the occurrence of overlapping chromosome territories. The spatial distribution of chromosomes may increase the possibility of chromosomal translocations in multiple myeloma. PMID- 27711973 TI - Pharmacological interventions other than botulinum toxin for spasticity after stroke. AB - BACKGROUND: The long-term risk of stroke increases with age, and stroke is a common cause of disability in the community. Spasticity is considered a significantly disabling impairment that develops in people who have had a stroke. The burden of care is higher in stroke survivors who have spasticity when compared with stroke survivors without spasticity with regard to treatment costs, quality of life, and caregiver burden. OBJECTIVES: To assess if pharmacological interventions for spasticity are more effective than no intervention, normal practice, or control at improving function following stroke. SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (May 2016), the Cochrane Central Register of Controlled Trials (CENTRAL, 2016, Issue 5), MEDLINE (1946 to May 2016), Embase (2008 to May 2016), CINAHL (1982 to May 2016), AMED (1985 to May 2016), and eight further databases and trial registers. In an effort to identify further studies, we undertook handsearches of reference lists and contacted study authors and commercial companies. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that compared any systemically acting or locally acting drug versus placebo, control, or comparative drug with the aim of treating spasticity. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the studies for inclusion and extracted the data. We assessed the included studies for both quality and risk of bias. We contacted study authors to request further information when necessary. MAIN RESULTS: We included seven RCTs with a total 403 participants. We found a high risk of bias in all but one RCT. Two of the seven RCTs assessed a systemic drug versus placebo. We pooled data on an indirect measure of spasticity (160 participants) from these two studies but found no significant effect (odds ratio (OR) 1.66, 95% confidence interval (CI) 0.21 to 13.07; I2 = 85%). We identified a significant risk of adverse events per participant occurring in the treatment group versus placebo group (risk ratio (RR) 1.65, 95% CI 1.12 to 2.42; 160 participants; I2 = 0%). Only one of these studies used a functional outcome measure, and we found no significant difference between groups.Of the other five studies, two assessed a systemic drug versus another systemic drug, one assessed a systemic drug versus local drug, and the final two assessed a local drug versus another local drug. AUTHORS' CONCLUSIONS: The lack of high-quality RCTs limited our ability to make specific conclusions. Evidence is insufficient to determine if systemic antispasmodics are effective at improving function following stroke. PMID- 27711974 TI - Next-generation sequencing-based detection of circulating tumour DNA After allogeneic stem cell transplantation for lymphoma. AB - Next-generation sequencing (NGS)-based circulating tumour DNA (ctDNA) detection is a promising monitoring tool for lymphoid malignancies. We evaluated whether the presence of ctDNA was associated with outcome after allogeneic haematopoietic stem cell transplantation (HSCT) in lymphoma patients. We studied 88 patients drawn from a phase 3 clinical trial of reduced-intensity conditioning HSCT in lymphoma. Conventional restaging and collection of peripheral blood samples occurred at pre-specified time points before and after HSCT and were assayed for ctDNA by sequencing of the immunoglobulin or T-cell receptor genes. Tumour clonotypes were identified in 87% of patients with adequate tumour samples. Sixteen of 19 (84%) patients with disease progression after HSCT had detectable ctDNA prior to progression at a median of 3.7 months prior to relapse/progression. Patients with detectable ctDNA 3 months after HSCT had inferior progression-free survival (PFS) (2-year PFS 58% vs. 84% in ctDNA negative patients, P = 0.033). In multivariate models, detectable ctDNA was associated with increased risk of progression/death (Hazard ratio 3.9, P = 0.003) and increased risk of relapse/progression (Hazard ratio 10.8, P = 0.0006). Detectable ctDNA is associated with an increased risk of relapse/progression, but further validation studies are necessary to confirm these findings and determine the clinical utility of NGS-based minimal residual disease monitoring in lymphoma patients after HSCT. PMID- 27711975 TI - Observational research rigour alone does not justify causal inference. AB - BACKGROUND: Differing opinions exist on whether associations obtained in observational studies can be reliable indicators of a causal effect if the observational study is sufficiently well controlled and executed. MATERIALS AND METHODS: To test this, we conducted two animal observational studies that were rigorously controlled and executed beyond what is achieved in studies of humans. In study 1, we randomized 332 genetically identical C57BL/6J mice into three diet groups with differing food energy allotments and recorded individual self selected daily energy intake and lifespan. In study 2, 60 male mice (CD1) were paired and divided into two groups for a 2-week feeding regimen. We evaluated the association between weight gain and food consumption. Within each pair, one animal was randomly assigned to an S group in which the animals had free access to food. The second paired animal (R group) was provided exactly the same diet that their S partner ate the day before. RESULTS: In study 1, across all three groups, we found a significant negative effect of energy intake on lifespan. However, we found a positive association between food intake and lifespan among the ad libitum feeding group: 29.99 (95% CI: 8.2-51.7) days per daily kcal. In study 2, we found a significant (P = 0.003) group (randomized vs. self-selected) by-food consumption interaction effect on weight gain. CONCLUSION: At least in nutrition research, associations derived from observational studies may not be reliable indicators of causal effects, even with the most rigorous study designs achievable. PMID- 27711977 TI - Evaluation of the Penetration of Multiple Classes of Pesticides in Fresh Produce Using Surface-Enhanced Raman Scattering Mapping. AB - Understanding pesticide penetration is important for effectively applying pesticides and in reducing pesticide exposures from food. This study aims to evaluate multiclass systemic and nonsystemic pesticide penetration in 3 representative fresh produce (apples, grapes, and spinach leaves). Surface enhanced Raman scattering mapping was applied for in situ and real-time tracking of pesticide penetration over time. The results show that 100 mg/L of systemic pesticides, thiabendazole and acetamiprid, penetrated more rapidly and deeply with maximum depth around 220 MUm after 48-h exposure into the tested fresh produce than 100 mg/L of nonsystemic pesticides, ferbam and phosmet, with maximum depth about 80 MUm. The fact that 2 nonsystemic pesticides were also able to penetrate over time into all 3 fresh produce tested may raise additional food safety concerns. Comparatively, grapes were generally more resistant for pesticide penetration with all pesticides penetration depth below 80 MUm compared to apples and spinach leaves. The information obtained here could provide technical support and guidance for accurate, effective, and safe application of pesticides and for the reduction of pesticide exposure from fresh produce. PMID- 27711976 TI - Identification of peptide sequences that selectively bind to pentaerythritol trinitrate hemisuccinate-a surrogate of PETN, via phage display technology. AB - The present research investigates the identification of amino acid sequences that selectively bind to a pentaerythritol tetranitrate (PETN) explosive surrogate. Through the use of a phage display technique and enzyme-linked immunosorbent assays (ELISA), a peptide library was tested against pentaerythritol trinitrate hemisuccinate (PETNH), a surrogate of PETN, to screen for those with amino acids having affinity toward the explosive. The results suggest that the library contains peptides selective to PETNH. Following three rounds of panning, clones were picked and tested for specificity toward PETNH. ELISA results from these samples show that each phage clone has some level of selectivity for binding to PETNH. The peptides from these clones have been sequenced and shown to contain certain common amino acid segments among them. This work represents a technological platform for identifying amino-acid sequences selective toward any bio-chem analyte of interest. PMID- 27711978 TI - Development and validation of an assessment tool for a national young worker curriculum. AB - BACKGROUND: An online, multiple-choice assessment was developed and validated for Youth@Work-Talking Safety, a NIOSH curriculum that equips middle and high school students with foundational workplace safety and health knowledge and skills. METHODS: Classical Test Theory was used for the test development and validation; the Jaeger method was used for cut score determination. A total of 118 multiple choice items were developed to measure the acquisition of knowledge and skills taught through the NIOSH curriculum. Pilot testing was conducted with 192 8-12th grade students and a cut score was determined. RESULTS: The mean score for all test-takers on the Talking Safety assessment was 80.9%; total test reliability measured using an Alpha/KR20 statistic was 0.93. A minimum passing (cut) score of 74% was established. CONCLUSIONS: The assessment provides an objective measure of students' acquisition of the foundational workplace safety and health competencies taught through the Talking Safety curriculum. Am. J.

PMID- 27711980 TI - Interventions for patients and caregivers to improve knowledge of sickle cell disease and recognition of its related complications. AB - BACKGROUND: Sickle cell disease is a group of genetic diseases which is especially prevalent in tropical and subtropical regions; however, forced migration and ongoing population movement have spread it throughout the world, with estimated birth rates reaching 0.49 per 1000 in the Americas, 0.07 per 1000 in Europe, 0.68 per 1000 in South and Southeast Asia, and 10.68 per 1000 in Africa. Life for individuals with sickle cell disease can be affected by repeated acute complications and compounded by progressive organ damage. Studies reveal that when people with chronic illness learn self-management, their clinical outcomes and quality of life improves; and they show lower dependence on healthcare services. There are, however, no reviews identifying which interventions improve knowledge and little is known about the impact of patient or care-giver knowledge on clinical and psychosocial outcomes in people with sickle cell disease. OBJECTIVES: 1. To determine the effectiveness of patient- and caregiver-centred educational interventions for changing knowledge and understanding of sickle cell disease among patients as well as caregivers of people with the disease.2. To assess the effectiveness and safety of patient- and caregiver-centred educational interventions and programs for the recognition of signs and symptoms of disease-related morbidity, adherence to treatment and healthcare utilization in patients with sickle cell disease. SEARCH METHODS: The authors searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. Additional trials were sought from the reference lists of the trials and reviews identified by the search strategy.Date of last search: 11 April 2016. SELECTION CRITERIA: Randomized and quasi-randomized controlled trials which evaluate the effectiveness of individual- and group-based interventions for either the patient with sickle cell disease or their caregivers, or both. Eligible interventions will aim to change knowledge, attitudes or skills, improve psychosocial aspects of the disease as well as treatment adherence and healthcare utilization. Trials evaluating the intervention versus no program, comparing two interventions and those which are part of a multi-faceted intervention to improve a range of sickle cell-related health outcomes are all eligible for inclusion. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials based on stated inclusion criteria and thereafter examined each selected report to extract data using a prepared, piloted, data collection form. A third author assisted in reaching consensus if there were any discrepancies. Similarly, risk of bias was assessed by two authors and verified by a third author. MAIN RESULTS: A total of 12 trials (11 randomized controlled trials and one quasi-randomized trial) of 563 people with HbSS, HbSC or HbSbetathal, aged six to 35 years old, were included in the review; the majority of participants were African-American. Interventions ranged from a total of one hour to weekly sessions for eight weeks and the post intervention assessments ranged from the end of the intervention period to 12 months after completion. The heterogeneity of the included trials, which encompasses setting, inclusion and exclusion criteria, interventional method and time of assessment, ranged from 'not important' to 'moderate to substantial' for different review outcomes. The overall risk of bias was low for selective reporting, unclear for random sequence generation, allocation concealment, blinding of participants and blinding of outcome assessment. Incomplete outcome reporting and blinding of personnel showed mixed bias representations.Patient knowledge was assessed by four trials (160 participants) with moderate to substantial heterogeneity. There was evidence that educational programs improved patient knowledge, standardised mean difference 0.87 points (95% confidence interval 0.28 to 1.45, moderate quality evidence), which improved further when a trial with high bias was removed in a sensitivity analysis. Caregiver knowledge, reported in a single trial of 20 families, also showed an improvement, standardised mean difference 0.52 points (95% confidence interval 0.03 to 1.00, moderate quality evidence). The effect on patient knowledge was sustained at longer follow-up periods, whereas the effect on caregiver knowledge was not sustained.There were two primary outcomes related to the effectiveness of educational programs on the recognition of signs and symptoms of disease-related morbidity. No comparative data were reported for patients or caregivers (or both) recognising signs and symptoms leading to self-management. Data from two trials were analysed for the utilization of health services and showed no evidence of an effect, mean difference 0.33 (95% confidence interval -0.57 to 1.23, moderate quality evidence).With regard to the review's secondary outcomes, depression showed a statistically significant decline in intervention groups, standardised mean difference -0.66 points (95% confidence interval -1.18, to -0.14, moderate quality evidence). Adherence to treatment was not assessed in any of the identified trials. No effects of interventions were seen on coping, family relationships or health-related quality of life of patients.The quality of evidence was low for positive coping and moderate for child knowledge, healthcare utilization and depression. This suggests that further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimates. AUTHORS' CONCLUSIONS: This review identifies important positive effects of educational interventions on improving patient knowledge of sickle cell disease and depression. Effects on patients' knowledge were maintained for longer than for caregivers. The effect on knowledge was significant but small and whether it offers any clinical benefit is uncertain. Significant factors limiting these effects could be trials being under powered as well as attrition rates. Effects were not statistically significant in assessments of secondary outcomes, possibly due to the paucity of the number of trials and patients and caregivers. Trials showed moderate to high heterogeneity which might impact the results. To better study effects on outcomes, further controlled trials are needed with rigorous attention given to improve recruitment and retention and to decrease bias. Predetermined protocols using similar measurements should be used across multiple sites. PMID- 27711981 TI - Assessing moderated mediation in linear models requires fewer confounding assumptions than assessing mediation. AB - It is well known from the mediation analysis literature that the identification of direct and indirect effects relies on strong no unmeasured confounding assumptions of no unmeasured confounding. Even in randomized studies the mediator may still be correlated with unobserved prognostic variables that affect the outcome, in which case the mediator's role in the causal process may not be inferred without bias. In the behavioural and social science literature very little attention has been given so far to the causal assumptions required for moderated mediation analysis. In this paper we focus on the index for moderated mediation, which measures by how much the mediated effect is larger or smaller for varying levels of the moderator. We show that in linear models this index can be estimated without bias in the presence of unmeasured common causes of the moderator, mediator and outcome under certain conditions. Importantly, one can thus use the test for moderated mediation to support evidence for mediation under less stringent confounding conditions. We illustrate our findings with data from a randomized experiment assessing the impact of being primed with social deception upon observer responses to others' pain, and from an observational study of individuals who ended a romantic relationship assessing the effect of attachment anxiety during the relationship on mental distress 2 years after the break-up. PMID- 27711979 TI - Innate immune responses in the ageing lung. AB - The world is undergoing an unprecedented shift in demographics, with the number of individuals over the age of 60 years projected to reach 2 billion or more by 2050, representing 22% of the global population. Elderly people are at a higher risk for chronic disease and more susceptible to infection, due in part to age related dysfunction of the immune system resulting from low-grade chronic inflammation known as 'inflamm-ageing'. The innate immune system of older individuals exhibits a diminished ability to respond to microbial threats and clear infections, resulting in a greater occurrence of many infectious diseases in elderly people. In particular, the incidence of and mortality from lung infections increase sharply with age, with such infections often leading to worse outcomes, prolonged hospital stays and life-threatening complications, such as sepsis or acute respiratory distress syndrome. In this review, we highlight research on bacterial pneumonias and pulmonary viral infections and discuss age related changes in innate immunity that contribute to the higher rate of these infections in older populations. By understanding more clearly the innate immune defects in elderly individuals, we can design age-specific therapies to address lung infections in such a vulnerable population. PMID- 27711983 TI - Hot spots become cold spots: coevolution in variable temperature environments. AB - Antagonistic coevolution between hosts and parasites is a key process in the genesis and maintenance of biological diversity. Whereas coevolutionary dynamics show distinct patterns under favourable environmental conditions, the effects of more realistic, variable conditions are largely unknown. We investigated the impact of a fluctuating environment on antagonistic coevolution in experimental microcosms of Pseudomonas fluorescens SBW25 and lytic phage SBWPhi2. High frequency temperature fluctuations caused no deviations from typical coevolutionary arms race dynamics. However, coevolution was stalled during periods of high temperature under intermediate- and low-frequency fluctuations, generating temporary coevolutionary cold spots. Temperature variation affected population density, providing evidence that eco-evolutionary feedbacks act through variable bacteria-phage encounter rates. Our study shows that environmental fluctuations can drive antagonistic species interactions into and out of coevolutionary cold and hot spots. Whether coevolution persists or stalls depends on the frequency of change and the environmental optima of both interacting players. PMID- 27711982 TI - Association of Anticholinergic Burden with Cognitive Impairment and Health Care Utilization Among a Diverse Ambulatory Older Adult Population. AB - STUDY OBJECTIVE: To determine the association between Anticholinergic Cognitive Burden (ACB) score and both cognitive impairment and health care utilization among a diverse ambulatory older adult population. DESIGN: Retrospective cohort study. DATA SOURCE: Medication exposure and other clinical data were extracted from the Regenstrief Medical Record System (RMRS), and cognitive diagnosis was derived from a dementia screening and diagnosis study. PATIENTS: A total of 3344 community-dwelling older adults (age 65 yrs and older) who were enrolled in a previously published dementia screening and diagnosis study; of these, 3127 were determined to have no cognitive impairment, and 217 were determined to have cognitive impairment. MEASUREMENTS AND MAIN RESULTS: The study followed a two phase screening and comprehensive neuropsychiatric examination to determine a cognitive diagnosis, which defined cognitive impairment as dementia or mild cognitive impairment. The ACB scale was used to identify anticholinergics dispensed in the 12 months prior to screening. A total daily ACB score was calculated by using pharmacy dispensing data from RMRS; each anticholinergic was multiplied by 1, 2, or 3 consistent with anticholinergic burden defined by the ACB scale. The sum of all ACB medications was divided by the number of days with any medication dispensed to achieve the total daily ACB score. Health care utilization included visits to inpatient, outpatient, and the emergency department, and it was determined by using visit data from the RMRS. The overall population had a mean age of 71.5 years, 71% were female, and 58% were African American. Each 1-point increase in mean total daily ACB score was associated with increasing risk of cognitive impairment (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.004-1.27, p=0.043). Each 1-point increase in mean total daily ACB score increased the likelihood of inpatient admission (OR 1.11, 95% CI 1.02-1.29, p=0.014) and number of outpatient visits after adjusting for demographic characteristics, number of chronic conditions, and prior visit history (estimate 0.382, standard error [SE] 0.113; p=0.001). The number of visits to the emergency department was also significantly different after similar adjustments (estimate 0.046, SE 0.023, p=0.043). CONCLUSION: Increasing total ACB score was correlated with an increased risk for cognitive impairment and more frequent health care utilization. Future work should study interventions that safely reduce ACB and evaluate the impact on brain health and health care costs. PMID- 27711984 TI - Ordinary least squares regression is indicated for studies of allometry. AB - When it comes to fitting simple allometric slopes through measurement data, evolutionary biologists have been torn between regression methods. On the one hand, there is the ordinary least squares (OLS) regression, which is commonly used across many disciplines of biology to fit lines through data, but which has a reputation for underestimating slopes when measurement error is present. On the other hand, there is the reduced major axis (RMA) regression, which is often recommended as a substitute for OLS regression in studies of allometry, but which has several weaknesses of its own. Here, we review statistical theory as it applies to evolutionary biology and studies of allometry. We point out that the concerns that arise from measurement error for OLS regression are small and straightforward to deal with, whereas RMA has several key properties that make it unfit for use in the field of allometry. The recommended approach for researchers interested in allometry is to use OLS regression on measurements taken with low (but realistically achievable) measurement error. If measurement error is unavoidable and relatively large, it is preferable to correct for slope attenuation rather than to turn to RMA regression, or to take the expected amount of attenuation into account when interpreting the data. PMID- 27711985 TI - Dysfunction of Arabidopsis MACPF domain protein activates programmed cell death via tryptophan metabolism in MAMP-triggered immunity. AB - Plant immune responses triggered upon recognition of microbe-associated molecular patterns (MAMPs) typically restrict pathogen growth without a host cell death response. We isolated two Arabidopsis mutants, derived from accession Col-0, that activated cell death upon inoculation with nonadapted fungal pathogens. Notably, the mutants triggered cell death also when treated with bacterial MAMPs such as flg22. Positional cloning identified NSL1 (Necrotic Spotted Lesion 1) as a responsible gene for the phenotype of the two mutants, whereas nsl1 mutations of the accession No-0 resulted in necrotic lesion formation without pathogen inoculation. NSL1 encodes a protein of unknown function containing a putative membrane-attack complex/perforin (MACPF) domain. The application of flg22 increased salicylic acid (SA) accumulation in the nsl1 plants derived from Col-0, while depletion of isochorismate synthase 1 repressed flg22-inducible lesion formation, indicating that elevated SA is needed for the cell death response. nsl1 plants of Col-0 responded to flg22 treatment with an RBOHD-dependent oxidative burst, but this response was dispensable for the nsl1-dependent cell death. Surprisingly, loss-of-function mutations in PEN2, involved in the metabolism of tryptophan (Trp)-derived indole glucosinolates, suppressed the flg22-induced and nsl1-dependent cell death. Moreover, the increased accumulation of SA in the nsl1 plants was abrogated by blocking Trp-derived secondary metabolite biosynthesis, whereas the nsl1-dependent hyperaccumulation of PEN2 dependent compounds was unaffected when the SA biosynthesis pathway was blocked. Collectively, these findings suggest that MAMP-triggered immunity activates a genetically programmed cell death in the absence of the functional MACPF domain protein NSL1 via Trp-derived secondary metabolite-mediated activation of the SA pathway. PMID- 27711987 TI - Physical Microfabrication of Shape-Memory Polymer Systems via Bicomponent Fiber Spinning. AB - As emerging technologies continue to require diverse materials capable of exhibiting tunable stimuli-responsiveness, shape-memory materials are of considerable significance because they can change size and/or shape in controllable fashion upon environmental stimulation. Of particular interest, shape-memory polymers (SMPs) have secured a central role in the ongoing development of relatively lightweight and remotely deployable devices that can be further designed with specific surface properties. In the case of thermally activated SMPs, two functional chemical species must be present to provide (i) an elastic network capable of restoring the SMP to a previous strain state and (ii) switching elements that either lock-in or release a temporary strain at a well defined thermal transition. While these species are chemically combined into a single macromolecule in most commercially available SMPs, this work establishes that, even though they are physically separated across one or more polymer/polymer interfaces, their shape-memory properties are retained in melt spun bicomponent fibers. In the present study, we investigate the effects of fiber composition and cross-sectional geometry on both conventional and cold-draw shape memory, and report surprisingly high levels of strain fixity and recovery that generally improve upon strain cycling. PMID- 27711986 TI - Esophageal carcinoma: Ex vivo evaluation by high-spatial-resolution T2 -mapping MRI compared with histopathological findings at 3.0T. AB - PURPOSE: To prospectively determine the feasibility of T2 -mapping magnetic resonance imaging (MRI) to quantitatively describe the signal characteristics of the normal esophageal wall and assess the depth of esophageal wall invasion by carcinoma at 3.0T. MATERIALS AND METHODS: Thirty-two patient specimens, each having foci of carcinoma, were studied using 3.0T MR. Freehand regions of interest were placed to measure the T2 value of the normal esophageal layers and were compared with the regions of carcinoma. Three independent readers reviewed the MR images to evaluate the depth of carcinoma invasion; when the three radiologists could not fully agree with each other, the final stage was determined by consensus. The Games-Howell test was used to compare the difference between the normal esophageal layers and carcinoma. Spearman correlation coefficient analysis was used to compare the stage at MRI with that at histopathological analysis. The interobserver agreement was compared with Cohen's kappa. The sensitivity, specificity, and accuracy for detecting carcinoma invasion were calculated. RESULTS: The T2 values between the carcinoma and normal esophageal layers were different (all P < 0.01), except for the inner circular muscle (P = 0.511). The T2 value of each layer of the normal esophageal wall was also different from that of the adjacent layer (all P < 0.01). In 29 of 32 lesions, the depth of the esophageal wall invasion determined by MR was consistent with the histopathological stage (r = 0.969, P < 0.001). The sensitivity, specificity, and accuracy were 80%, 96.3%, and 93.8%, respectively, for invasion into the mucosa; 77.8%, 95.7%, and 90.6%, respectively, for invasion into submucosa; 100%, 95.8%, and 96.9%, respectively, for invasion into muscularis propria; and 100%, 100%, and 100%, respectively, for invasion into the adventitia. CONCLUSION: T2 -mapping MR images obtained using a 3.0T MR scanner can be used to depict the precise histopathological layers of the esophageal wall clearly and provide excellent diagnostic accuracy for assessing esophageal carcinoma invasion.

PMID- 27711988 TI - Status of Removable Dentures and Relationship with Oral Candida-Associated Factors in a Geriatric Population in Catalonia. AB - PURPOSE: Colonization by Candida is related to wearing a denture. How denture type, status, and maintenance play a role in determining Candida colonization remains unknown. This work evaluated removable denture status in an elderly population and explored the association between denture-related factors and oral Candida colonization as determined by systemic and local factors. MATERIALS AND METHODS: Socio-demographic, general health, and behavioral data and oral factors were registered by means of a questionnaire. Oral, dental, and denture-related factors were assessed by clinical examination, and yeasts were isolated from oral and denture specimens. Multiple logistic regression analysis was used to explore the relative relevance of risk factors. RESULTS: Overall, 52.4% of subjects used complete dentures in both lower and upper arches, and 90% of the prostheses were in good condition. Denture plaque index was high in most cases, and 75% of subjects had yeasts in their oral cavities. Oral Candida colonization was significantly associated with low saliva pH, sugar consumption, and the fault of a denture component; however, only sugar consumption was found to be an independent factor related with oral Candida colonization, showing an odds ratio of 3.04 in a multiple logistic regression model. CONCLUSIONS: Elderly people in this study used a complete denture in good condition, with a median age of 15 years. Daily or weekly sugar consumption was found to be highly associated with oral colonization by Candida.

PMID- 27711990 TI - Identification of fungal candidates for asthma protection in a large population based study. AB - BACKGROUND: Exposure to molds has been related to asthma risk both positively and negatively, depending on the environmental setting. The pertinent results are based on generic markers or culturing methods although the majority of present fungi cannot be cultured under laboratory conditions. The aim of the present analysis was to assess environmental dust samples for asthma-protective fungal candidates with a comprehensive molecular technique covering also non-cultivable and non-viable fungi. METHODS: Mattress dust samples of 844 children from the GABRIELA study were analyzed by polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) of the fungus-specific internal transcribed spacer (ITS) region. Known asthma candidate species were tested for their associations with asthma, and further gel positions were sought to explain the above. As a second, data-driven, analysis, we tested the association of each individual gel position with asthma. RESULTS: In the hypothesis-driven approach, Penicillium chrysogenum emerged with an odds ratio of 0.80 (95% confidence interval 0.66-0.96; p = 0.020). The effect size was changed by 39% toward the null when adjusting for the two bands 683 (DNA of Metschnikowia sp., Aureobasidium spp.) and 978 (DNA of Epicoccum spp., Galactomyces spp., uncultured Penicillium). The data-driven approach yielded an additional band (containing DNA of Pseudotaeniolina globosa) with reduced risk of asthma (OR = 0.80 [0.66-0.96], p = 0.012). CONCLUSIONS: A large population-based study revealed several fungal taxa with inverse associations with childhood asthma. Molds produce a variety of bioactive compounds with detrimental but also beneficial immunoregulatory capacities, which renders them promising targets for further asthma research. PMID- 27711992 TI - ABI4 represses the expression of type-A ARRs to inhibit seed germination in Arabidopsis. AB - The plant hormone abscisic acid (ABA) plays a crucial role in regulating seed germination and post-germination growth. ABSCISIC ACID INSENSITIVE4 (ABI4), an APETALA2 (AP2)-type transcription factor, is required for the ABA-mediated inhibition of seed germination. Cytokinins promote seed germination and seedling growth by antagonizing ABA signaling. However, the interaction between ABA and cytokinin signaling during seed germination remains unclear. Here, we report that ABA signaling downregulates Arabidopsis response regulators (ARRs), a class of cytokinin-inducible genes, during seed germination and cotyledon greening. We found that the application of exogenous ABA repressed the expression of type-A ARRs in Arabidopsis seeds and seedlings. Among the type-A ARR family members, the expression of ARR6, ARR7 and ARR15 was upregulated in ABA-deficient mutants, indicating that the transcriptional inhibition of type-A ARRs requires the ABA signaling pathway. Single and multiple mutations of these ARRs resulted in increased ABA sensitivity during germination and cotyledon greening; overexpression of ARR7 or ARR15 led to an ABA-insensitive phenotype. These observations suggest that type-A ARRs inhibit the ABA response during seed germination and cotyledon greening. Further analysis showed that ABI4 negatively regulated the transcription of ARR6, ARR7 and ARR15 by directly binding to their promoters. Genetic analysis showed that loss-of-function mutations of ARR7 and ARR15 partially rescued the ABA insensitivity of abi4-1. Thus, this study revealed that ABI4 plays a key role in ABA and cytokinin signaling by inhibiting the transcription of type-A ARRs to inhibit seed germination and cotyledon greening. PMID- 27711994 TI - Methods and terminology used in cell-culture studies of low-dose effects of matrix constituents of polymer resin-based dental materials. AB - General comprehension of terms and confounding factors associated with in vitro experiments can maximize the potential of in vitro testing of substances. In this systematic review, we present an overview of the terms and methods used to determine low-dose effects of matrix constituents in polymer resin-based dental materials in cell-culture studies and discuss the findings in light of how they may influence the comprehension and interpretation of results. Articles published between 1996 and 2015 were identified by searches in the Scopus, Web of Science, MEDLINE, PubMed, and Embase databases using keywords associated with low-dose effects, polymer resin-based materials, in vitro parameters, and dental materials. Twenty-nine articles were included. Subtoxic (n = 11), sublethal (n = 10), and nontoxic (n = 6) were the terms most commonly used to describe the low dose effects of methacrylates. However, definition of terms varied. Most (82%) studies employed only one method to define the exposure scenario, and no agreement was seen between studies on the use of solvents. Prophylactic use of antibiotics was widespread, and mycoplasma screening was not reported. In conclusion, cell-culture conditions and tests used to define exposure scenarios have changed little in the last decades, despite development in recommendations. Nomenclature alignment is needed for a better understanding of possible biohazards of methacrylates. PMID- 27711993 TI - High sensitivity of spontaneous spike frequency to sodium leak current in a Lymnaea pacemaker neuron. AB - The spontaneous rhythmic firing of action potentials in pacemaker neurons depends on the biophysical properties of voltage-gated ion channels and background leak currents. The background leak current includes a large K+ and a small Na+ component. We previously reported that a Na+ -leak current via U-type channels is required to generate spontaneous action potential firing in the identified respiratory pacemaker neuron, RPeD1, in the freshwater pond snail Lymnaea stagnalis. We further investigated the functional significance of the background Na+ current in rhythmic spiking of RPeD1 neurons. Whole-cell patch-clamp recording and computational modeling approaches were carried out in isolated RPeD1 neurons. The whole-cell current of the major ion channel components in RPeD1 neurons were characterized, and a conductance-based computational model of the rhythmic pacemaker activity was simulated with the experimental measurements. We found that the spiking rate is more sensitive to changes in the Na+ leak current as compared to the K+ leak current, suggesting a robust function of Na+ leak current in regulating spontaneous neuronal firing activity. Our study provides new insight into our current understanding of the role of Na+ leak current in intrinsic properties of pacemaker neurons.

AB - Alopecia areata (AA) affects anagen hair follicles, resulting in non-scarring hair loss. Since introduced by Huang et al., superficial cryotherapy has been accepted as a considerable primary therapeutic modality for AA. The aim of this study was to objectively clarify the therapeutic efficacy and safety of superficial hypothermic cryotherapy for treatment of AA. Medical records of 353 patients from 1993 to 2014 were retrospectively analyzed. According to the response to the superficial cryotherapy, patients were categorized into four groups: "marked", "partial", "poor" and "no recovery". The marked and partial recovery groups were considered as responders. The proportions of the responders among patient subgroups which were defined by various patients, disease, and treatment factors were compared. Of the patients, 60.9% were classified as responders after 3 months of superficial hypothermic cryotherapy. The proportion of the responders were higher when the treatment interval was 2 weeks or less and in the incipient disease stage, with statistical significance. No severe side effects other than mild pain and pruritus were reported. In conclusion, superficial cryotherapy is an effective and safe therapeutic modality for AA. Especially when the treatment interval is 2 weeks or less and in the first occurrence of the disease, the therapeutic outcome is superior.

PMID- 27711998 TI - VTA dopamine neuron plasticity - the unusual suspects. AB - Dopamine neurons in the ventral tegmental area (VTA) are involved in a variety of physiological and pathological conditions, ranging from motivated behaviours to substance use disorders. While many studies have shown that these neurons can express plasticity at excitatory and inhibitory synapses, little is known about how inhibitory inputs and glial activity shape the output of DA neurons and therefore, merit greater discussion. In this review, we will attempt to fill in a bit more of the puzzle, with a focus on inhibitory transmission and astrocyte function. We summarize the findings within the VTA as well as observations made in other brain regions that have important implications for plasticity in general and should be considered in the context of DA neuron plasticity. PMID- 27712001 TI - Alveolar ridge preservation after tooth extraction: a Bayesian Network meta analysis of grafting materials efficacy on prevention of bone height and width reduction. AB - AIMS: To conduct a traditional meta-analysis and a Bayesian Network meta-analysis to synthesize the information coming from randomized controlled trials on different socket grafting materials and combine the resulting indirect evidence in order to make inferences on treatments that have not been compared directly. MATERIALS AND METHODS: RCTs were identified for inclusion in the systematic review and subsequent statistical analysis. Bone height and width remodelling were selected as the chosen summary measures for comparison. First, a series of pairwise meta-analyses were performed and overall mean difference (MD) in mm with 95% CI was calculated between grafted versus non-grafted sockets. Then, a Bayesian Network meta-analysis was performed to draw indirect conclusions on which grafting materials can be considered most likely the best compared to the others. RESULTS: From the six included studies, seven comparisons were obtained. Traditional meta-analysis showed statistically significant results in favour of grafting the socket compared to no-graft both for height (MD 1.02, 95% CI 0.44 1.59, p value < 0.001) than for width (MD 1.52 95% CI 1.18-1.86, p value <0.000001) remodelling. Bayesian Network meta-analysis allowed to obtain a rank of intervention efficacy. CONCLUSIONS: On the basis of the results of the present analysis, socket grafting seems to be more favourable than unassisted socket healing. Moreover, Bayesian Network meta-analysis indicates that freeze-dried bone graft plus membrane is the most likely effective in the reduction of bone height remodelling. Autologous bone marrow resulted the most likely effective when width remodelling was considered. Studies with larger samples and less risk of bias should be conducted in the future in order to further strengthen the results of this analysis.

AB - Cyclic amines such as pyrrolidine and piperidine are known to undergo condensations with aldehydes to furnish pyrrole and pyridine derivatives, respectively. A combined experimental and computational study provides detailed insights into the mechanism of pyrrole formation. A number of reactive intermediates (e.g., azomethine ylides, conjugated azomethine ylides, enamines) were intercepted, outlining strategies for circumventing aromatization as a valuable pathway for amine C-H functionalization. PMID- 27712002 TI - Multi-parameter machine learning approach to the neuroanatomical basis of developmental dyslexia. AB - Despite decades of research, the anatomical abnormalities associated with developmental dyslexia are still not fully described. Studies have focused on between-group comparisons in which different neuroanatomical measures were generally explored in isolation, disregarding potential interactions between regions and measures. Here, for the first time a multivariate classification approach was used to investigate grey matter disruptions in children with dyslexia in a large (N = 236) multisite sample. A variety of cortical morphological features, including volumetric (volume, thickness and area) and geometric (folding index and mean curvature) measures were taken into account and generalizability of classification was assessed with both 10-fold and leave-one out cross validation (LOOCV) techniques. Classification into control vs. dyslexic subjects achieved above chance accuracy (AUC = 0.66 and ACC = 0.65 in the case of 10-fold CV, and AUC = 0.65 and ACC = 0.64 using LOOCV) after principled feature selection. Features that discriminated between dyslexic and control children were exclusively situated in the left hemisphere including superior and middle temporal gyri, subparietal sulcus and prefrontal areas. They were related to geometric properties of the cortex, with generally higher mean curvature and a greater folding index characterizing the dyslexic group. Our results support the hypothesis that an atypical curvature pattern with extra folds in left hemispheric perisylvian regions characterizes dyslexia. Hum Brain Mapp 38:900 908, 2017.

AB - Photosynthesis is known to produce reactive oxygen species together with the transformation of light into biochemical energy. To fill the gap of the knowledge on the protective antioxidant network of microalgae, a series of experiments to explore the role of spectral composition and intensity of light in the modulation of the photodefence mechanisms developed by the coastal diatom Skeletonema marinoi were performed. The modulation of the total phenolic content, ascorbic acid and the enzymes glutathione reductase, catalase, ascorbate peroxidase and superoxide dismutase together with xanthophyll cycle and non-photochemical quenching in response to variations in the light environment were analysed. Most of the enzymes' activity was promptly affected by the red light. Yet, the monochromatic high intensity blue light enhanced the synthesis of total phenolic content and ascorbic acid in parallel to the xanthophyll cycle activity. This study reveals the dual effects of spectral composition and intensity of light on the modulation of photoprotective mechanisms. Diatoms developed a complementary and/or alternative tuning processes to cope with the variable light environment they experience in the water column. They also provided valuable insights into light manipulation regimes for diatom cultivation that will help to maximize production of bioactive molecules. PMID- 27712005 TI - Glyoxal measurement with a proton transfer reaction time of flight mass spectrometer (PTR-TOF-MS): characterization and calibration. AB - We examine the potential for PTR-TOF-MS systems to quantitatively measure glyoxal in ambient air by characterizing the response of the instrument to a dilute glyoxal sample, calibrating the system as a function of humidity. The concentration of glyoxal in a sample air-stream was measured with an UV absorption spectrometer in parallel to a PTR-TOF-MS. This calibration demonstrated that the PTR-TOF-MS has a relatively low sensitivity to glyoxal particularly at high humidity. Extensive fragmentation of glyoxal to formaldehyde was observed. This behaviour not only desensitizes PTR-MS system to glyoxal; it may also pose a problem to the quantification of formaldehyde. (c) 2016 The Authors.

AB - Increased pulmonary vascular resistance is a critical complication in sepsis. Toll-like receptor (TLR) as well as angiopoietin (ANG) signalling both contribute to the emergence of pulmonary arterial hypertension. We hypothesized that TLR stimulation by bacterial ligands directly affects expression and secretion of ligands and receptors of the angiopoietin/TIE axis. Microvascular endothelial (HPMEC) and smooth muscle cells (SMC) of pulmonary origin were incubated with thrombin and with ligands for TLR2, -4, -5, and -9. Expression and secretion of ANG1, -2, TIE2 and IL-8 were determined using quantitative real-time PCR and ELISA. TLR stimulation had no impact either on the expression of ANG2 and TIE2 in HPMEC or on that of ANG1 in SMC. However, overall levels of both released ANG1 and -2 were halved upon stimulation with the TLR9 ligand CpG, and ANG2 release was significantly enhanced by TLR4 activation when initially provoked by sequentially performed stimulation. Furthermore, enhanced ANG2 activity increased endothelial permeability, as demonstrated in an in vitro transwell assay. We conclude that sole TLR stimulation by bacterial ligands plays no significant role for altered expression and secretion of ANG1, -2 and TIE2 in human pulmonary vascular cells. The interplay between various stimuli is required to induce imbalances between ANG1 and -2.

PMID- 27712007 TI - A Cooperative Strategy for the Highly Selective Intermolecular Oxycarbonylation Reaction of Alkenes using a Palladium Catalyst. AB - A novel method for intermolecular functionalization of terminal and internal alkenes has been designed. The electrophilic reagent, hypervalent iodine, plays a key role in this process by activating the alkene C=C bond for nucleophilic addition of the palladium catalyst. This process generates an iodonium-containing palladium species which undergoes CO insertion. The new approach, intermolecular oxycarbonylaton reactions of alkenes, has been achieved and carried out under mild reaction conditions to produce the corresponding beta-oxycarbonylic acids with excellent efficiencies and levels of regio- and diastereoselectivity. PMID- 27711999 TI - NMR Hyperpolarization Techniques of Gases. AB - Nuclear spin polarization can be significantly increased through the process of hyperpolarization, leading to an increase in the sensitivity of nuclear magnetic resonance (NMR) experiments by 4-8 orders of magnitude. Hyperpolarized gases, unlike liquids and solids, can often be readily separated and purified from the compounds used to mediate the hyperpolarization processes. These pure hyperpolarized gases enabled many novel MRI applications including the visualization of void spaces, imaging of lung function, and remote detection. Additionally, hyperpolarized gases can be dissolved in liquids and can be used as sensitive molecular probes and reporters. This Minireview covers the fundamentals of the preparation of hyperpolarized gases and focuses on selected applications of interest to biomedicine and materials science. PMID- 27712008 TI - Overexpression of a tomato miR171 target gene SlGRAS24 impacts multiple agronomical traits via regulating gibberellin and auxin homeostasis. AB - In Arabidopsis, the miR171-GRAS module has been clarified as key player in meristem maintenance. However, the knowledge about its role in fruit crops like tomato (Solanum lycopersicum) remains scarce. We previously identified tomato SlGRAS24 as a target gene of Sly-miR171. To study the role of this probable transcription factor, we generated transgenic tomato plants underexpressing SlGRAS24, overexpressing SlGRAS24, overexpressing Sly-miR171 and expressing beta glucuronidase (GUS) under the SlGRAS24 promoter (proSlGRAS24-GUS). Plants overexpressing SlGRAS24 (SlGRAS24-OE) had pleiotropic phenotypes associated with multiple agronomical traits including plant height, flowering time, leaf architecture, lateral branch number, root length, fruit set and development. Many GA/auxin-related genes were down-regulated and altered responsiveness to exogenous IAA/NAA or GA3 application was observed in SlGRAS24-OE seedlings. Moreover, compromised fruit set and development in SlGRAS24-OE was also observed. These newly identified phenotypes for SlGRAS24 homologs in tomato were later proved to be caused by impaired pollen sacs and fewer viable pollen grains. At anthesis, the comparative transcriptome results showed altered expression of genes involved in pollen development and hormone signalling. Taken together, our data demonstrate that SlGRAS24 participates in a series of developmental processes through modulating gibberellin and auxin signalling, which sheds new light on the involvement of hormone crosstalk in tomato development. PMID- 27712009 TI - Broad phylogeny and functionality of cellulosomal components in the bovine rumen microbiome. AB - The cellulosome is an extracellular multi-enzyme complex that is considered one of the most efficient plant cell wall-degrading strategies devised by nature. Its unique modular architecture, achieved by high affinity and specific interaction between protein modules (cohesins and dockerins) enables formation of various enzyme combinations. Extensive research has been dedicated to the mechanistic nature of the cellulosome complex. Nevertheless, little is known regarding its distribution and abundance among microbes in natural plant fibre-rich environments. Here, we explored these questions in bovine rumen microbial communities, specialized in efficient degradation of lignocellulosic plant material. We bioinformatically screened for cellulosomal modules in this complex environment using a previously published ultra-deep fibre-adherent rumen metagenome. Intriguingly, a large portion of the functions of the dockerin containing proteins were related to alternative biological processes, and not necessarily to the classic fibre degradation function. Our analysis was experimentally validated by characterizing specific interactions between selected cohesins and dockerins and revealed that cellulosome is a more generalized strategy used by diverse bacteria, some of which were not previously associated with cellulosome production. Remarkably, our results provide additional proof of similarity among rumen microbial communities worldwide. This study suggests a broader and widespread role for the cellulosomal machinery in nature. PMID- 27712010 TI - Hepatic manifestations of inflammatory bowel diseases. AB - Inflammatory bowel diseases are associated with various hepatobiliary disorders, reported both in Crohn's disease and ulcerative colitis. They may occur at any moment in the natural course of the disease. The prevalence of liver dysfunction rises from 3% to 50% accordingly to definitions used in different studies. Fatty liver is considered as the most common hepatobiliary complication in inflammatory bowel diseases while primary sclerosing cholangitis is the most specific one. Less frequently, inflammatory bowel diseases-associated hepatobiliary disorders include: autoimmune hepatitis/ primary sclerosing cholangitis overlap syndrome, IgG4-associated cholangiopathy, primary biliary cholangitis, hepatic amyloidosis, granulomatous hepatitis, cholelithiasis, portal vein thrombosis and liver abscess. The spectrum of these manifestations varies according to the type of inflammatory bowel diseases. Treatments of inflammatory bowel diseases may cause liver toxicity, although incidence of serious complications remains low. However, early diagnosis of drug-induced liver injury is of major importance as it affects future clinical management. When facing abnormal liver tests, clinicians should undertake a full diagnostic work-up in order to determine whether the hepatic abnormalities are related to the inflammatory bowel diseases or not. Management of hepatic manifestations in inflammatory bowel diseases usually involves both hepatologists and gastroenterologists because of the complexity of some situations. PMID- 27712011 TI - Theory of Ultralong-Range Rydberg Molecule Formation Incorporating Spin-Dependent Relativistic Effects: Cs(6s)-Cs(np) as Case Study. AB - We calculate vibrational spectra of ultralong-range Cs(32p) Rydberg molecules that form in an ultracold gas of Cs atoms. We account for the partial-wave scattering of the Rydberg electrons from the Cs perturber atoms by including the full set of spin-resolved 1,3 SJ and 1,3 PJ scattering phase shifts, and allow for the mixing of singlet (S=0) and triplet (S=1) spin states through Rydberg electron spin-orbit and ground state electron hyperfine interactions. Excellent agreement with observed data in Sabetamannshausen et al. [Phys. Rev. Lett. 2015, 113, 133201] in line positions and profiles is obtained. We also determine the spin-dependent permanent electric dipole moments for these molecules. This is the first such calculation of ultralong-range Rydberg molecules for which all of the relativistic contributions are accounted. PMID- 27712012 TI - Impulsive Collision Dynamics of CO Super Rotors from an Optical Centrifuge. AB - We report state-resolved collision dynamics for CO molecules prepared in an optical centrifuge and measured with high-resolution transient IR absorption spectroscopy. Time-resolved polarization-sensitive measurements of excited CO molecules in the J=29 rotational state reveal that the oriented angular momentum of CO rotors is relaxed by impulsive collisions. The translational energy gains for molecules in the initial plane of rotation are threefold larger than for randomized angular momentum orientations, indicating the presence of anisotropic kinetic energy. The transient data show enhanced population for CO molecules in the initial plane of rotation immediately following the optical centrifuge pulse. A comparison with previous CO2 super rotor studies illustrates the behavior of molecular gyroscopes; spatial reorientation of CO2 J=76 rotors takes substantially longer than that for CO J=29 rotors, despite similarities in classical rotational period and rotational energy gap. High-resolution transient IR absorption measurements of the CO J=29-39 rotational states show that the collisional depopulation rates increase with J quantum number. PMID- 27712013 TI - An in vitro comparison of the effects of voluven (6% hydroxyethyl starch 130/0.4) and hespan (6% hydroxyethyl starch 670/0.75) on measures of blood coagulation in canine blood. AB - OBJECTIVE: To assess primary and secondary hemostasis following in vitro dilution of canine whole blood (WB) with hydroxyethyl starch (HES) 130/0.4 and HES 670/0.75. DESIGN: In vitro experimental study. SETTING: Private practice, teaching hospital. ANIMALS: Twenty-five healthy dogs. INTERVENTIONS: Each dog underwent venipuncture and 18 mL of venous blood was sampled once. MEASUREMENTS AND MAIN RESULTS: Collected blood was separated in 4 aliquots. Aliquot A served as baseline sample. The remaining tubes of WB were diluted with 0.9% saline, HES 670/0.75 and HES 130/0.4 at a ratio of 1:5.5. Dilutional effects were evaluated using prothrombin time (PT), activated partial thromboplastin time (aPTT), packed cell volume (PCV), thromboelastography (TEG), and platelet closure time (Ct), which was measured using a platelet function analyzer (PFA). Clot strength (ie, G value) was calculated from measured TEG values. Significant increases in PT (P < 0.05) and aPTT (P < 0.05) were documented following WB dilution with saline. Dilution of WB with HES 670/0.75 and HES 130/0.4 resulted in significant hypocoagulable changes in K, MA and G (P < 0.05) compared to baseline and saline. When comparing saline to HES 670/0.75, both R and K values were significantly increased (P < 0.05). K value was significantly increased (P < 0.05) when comparing baseline to HES 130/0.4 and HES 670/0.75. Ct (P < 0.05) was significantly prolonged after WB dilution with HES solutions but not after saline. CONCLUSIONS: Dilution of WB with HES 670/0.75 and HES 130/0.4 resulted in changes in primary and secondary hemostasis. Although there were small differences between saline and HES 670/0.75, no differences between HES solutions were evident in this small study. This may suggest there would be minimal increases in bleeding risk when either solution is administered to dogs at low doses. Clinical relevance of our findings requires further investigation. PMID- 27712014 TI - Generation of a NK1R-CreER knockin mouse strain to study cells involved in Neurokinin 1 Receptor signaling. AB - The Neurokinin 1 Receptor (NK1R), which binds Substance P, is expressed in discrete populations of neurons throughout the nervous system, where it has numerous roles including the modulation of pain and affective behaviors. Here, we report the generation of a NK1R-CreER knockin allele, in which CreERT2 replaces the coding sequence of the TACR1 gene (encoding NK1R) in order to gain genetic access to these cells. We find that the NK1R-CreER allele mediates recombination in many regions of the nervous system that are important in pain and anxiety including the amygdala, hypothalamus, frontal cortex, raphe nucleus, and dorsal horn of the spinal cord. Other cell types that are labeled by this allele include amacrine cells in the retina and fibroblasts in the skin. Thus, the NK1R-CreER mouse line is a valuable new tool for conditional gene manipulation enabling the visualization and manipulation of cells that express NK1R. PMID- 27712016 TI - Post-transplant blood transfusions and pediatric renal allograft outcomes. AB - The association of blood transfusions with GS after pediatric KTx is unclear. We retrospectively analyzed blood transfusions post-KTx and subsequent outcomes. Between 1984 and 2013, 482 children (<18 years of age) underwent KTx at our center. Recipient demographics, outcomes and transfusion data were collected. Cox regression with post-KTx blood transfusion as a time-dependent covariate was performed to model the impact of blood transfusion on outcomes. Of the 208 (44%) that were transfused, 39% had transfusion <1 month post-KTx; 48% >12 months. Transfused and non-transfused recipients were not significantly different. In univariate and multivariate analyses, there was no difference between transfused and non-transfused recipient patient survival, antibody-mediated and ACR, and DSA free survival. Transfusions <1 month post-KTx did not impact DCGS (P=NS). Patients transfused >12 months post-KTx had significantly lower 12 month eGFR (compared to non-transfused) and worse subsequent DCGS. Post-KTx blood transfusions have increased in pediatric KTx over time but have no negative association with rejection or DSA production. DCGS is unaffected by transfusion within first month. Transfusions after the first year occur in patients with more advanced chronic kidney disease and are associated with significantly worse DCGS. PMID- 27712015 TI - Randomized study of FOLFIRI plus either panitumumab or bevacizumab for wild-type KRAS colorectal cancer-WJOG 6210G. AB - This randomized phase II trial compared panitumumab plus fluorouracil, leucovorin, and irinotecan (FOLFIRI) with bevacizumab plus FOLFIRI as second-line chemotherapy for wild-type (WT) KRAS exon 2 metastatic colorectal cancer (mCRC) and to explore the values of oncogenes in circulating tumor DNA (ctDNA) and serum proteins as predictive biomarkers. Patients with WT KRAS exon 2 mCRC refractory to first-line chemotherapy containing oxaliplatin and bevacizumab were randomly assigned to panitumumab plus FOLFIRI or bevacizumab plus FOLFIRI. Of 121 randomly assigned patients, 117 were eligible. Median overall survival (OS) for panitumumab plus FOLFIRI and bevacizumab plus FOLFIRI were 16.2 and 13.4 months [hazard ratio (HR), 1.16; 95% CI, 0.76-1.77], respectively. Progression-free survival (PFS) was also similar (HR, 1.14; 95% CI, 0.78-1.66). KRAS, NRAS, and BRAF status using ctDNA was successfully examined in 109 patients, and mutations were identified in 19 patients (17.4%). Panitumumab plus FOLFIRI showed favorable survival compared with bevacizumab plus FOLFIRI in WT patients and unfavorable survival in those with mutations (P for interaction = 0.026 in OS and 0.054 in PFS). OS with bevacizumab plus FOLFIRI was better than panitumumab plus FOLFIRI in patients with high serum vascular endothelial growth factor-A (VEGF-A) levels and worse in those with low levels (P for interaction = 0.016). Second-line FOLFIRI plus panitumumab and FOLFIRI plus bevacizumab showed a similar efficacy in patients with WT KRAS exon 2 mCRC. RAS and BRAF mutation in ctDNA could be a negative predictive marker for panitumumab. PMID- 27712018 TI - Prevalence of hair shedding among women. AB - Hair shedding in female patients is a frequent complaint in dermatological, endocrinological, and gynecological consults. Previously, the Sinclair Hair Shedding Scale was developed to assess normal versus excessive hair shedding in female pattern hair loss (FPHL) subjects. However, the prevalence of hair shedding in females not suffering from FPHL is unknown. To gain better understanding of hair shedding in the general population, we recruited 300 subjects visiting a public hospital for conditions other than alopecia. Of the 300 subjects recruited, 263 did not suffer from FPHL. Among those subjects, approximately 40% reported experiencing excessive hair shedding (as defined by the Sinclair Hair Shedding Scale) on hair washing days. In comparison, in our subject population, approximately 60% of subjects with FPHL reported excessive hair shedding on hair washing days. To best of our knowledge, this is the first study to quantify the prevalence of hair shedding in women. While, no treatment currently exists for this condition, we hope that this study would encourage physicians and researchers to address this frequent concern. PMID- 27712017 TI - Real life Egyptian experience of efficacy and safety of Simeprevir/Sofosbuvir therapy in 6211 chronic HCV genotype IV infected patients. AB - BACKGROUND & AIMS: Major changes have emerged during the last few years in the therapy of chronic HCV. Several direct acting antiviral agents have been developed showing potent activity with higher rates of sustained virological response, even in difficult-to-treat patients. This study explores real life experience concerning efficacy, safety and possible predictors of response for the first cohort of Egyptian patients with chronic HCV genotype IV treated with Sofosbuvir/Simprevir combination therapy. METHODS: This real life study recruited the first (6211) chronic HCV genotype IV Egyptian patients, who received antiviral therapy in viral hepatitis specialized treatment centres affiliated to the National committee for control of viral hepatitis. All enrolled patients received 12 weeks course of daily combination of sofosbuvir (400 mg) and simeprevir (150 mg). Patients were closely monitored for treatment safety and efficacy. RESULTS: Overall sustained virological response 12 rate was 94.0% while the end of treatment response rate was 97.6%. sustained virological response 12 rates in easy and difficult-to-treat groups were 96% and 93% respectively. Univariate and multivariate logistic regression analysis revealed significant association of low albumin (<3.5), cirrhosis and Fib-4 score (>3.25) with treatment failure. Fatal adverse events occurred in 23/6211 cases (0.37%) due to liver cell failure adverse events or SAEs leading to treatment discontinuation occurred in 97 patients (1.6%). CONCLUSION: Sofosbuvir/Simeprevir combination is an effective and well tolerated regimen for patients with chronic HCV genotype IV. PMID- 27712019 TI - Highly Efficient Cooperative Catalysis by CoIII (Porphyrin) Pairs in Interpenetrating Metal-Organic Frameworks. AB - A series of porous twofold interpenetrated In-CoIII (porphyrin) metal-organic frameworks (MOFs) were constructed by in situ metalation of porphyrin bridging ligands and used as efficient cooperative catalysts for the hydration of terminal alkynes. The twofold interpenetrating structure brings adjacent CoIII (porphyrins) in the two networks parallel to each other with a distance of about 8.8 A, an ideal distance for the simultaneous activation of both substrates in alkyne hydration reactions. As a result, the In-CoIII (porphyrin) MOFs exhibit much higher (up to 38 times) catalytic activity than either homogeneous catalysts or MOF controls with isolated CoIII (porphyrin) centers, thus highlighting the potential application of MOFs in cooperative catalysis. PMID- 27712020 TI - Anti-PD-L1 treatment enhances antitumor effect of everolimus in a mouse model of renal cell carcinoma. AB - Immunotherapy based on blockade of the programmed death-1 (PD-1)/programmed death ligand 1 (PD-L1) axis has shown promising clinical activity for renal cell carcinoma (RCC) patients; however, the most effective use of these agents in combination with conventional targeted therapy remains to be resolved. Here we evaluated the therapeutic efficacy of the combination of the mTOR inhibitor everolimus (EVE) and anti-PD-L1 using an immunocompetent mouse model of RCC. We first assessed the in vitro effect of EVE on PD-L1 expression in the human 786-O and mouse RENCA RCC cell lines and found that EVE upregulated PD-L1 expression in these RCC cell lines. We then treated RENCA tumor-bearing mice with EVE and found that PD-L1 expression was also increased in tumor cells after EVE treatment. To determine the antitumor effects of EVE alone, anti-PD-L1 alone, and EVE in combination with anti-PD-L1, we evaluated their antitumor effects on RENCA tumor bearing mice. A significant decrease in the tumor burden was observed in the EVE alone but not in the anti-PD-L1 alone treatment group compared with the control group. Importantly, the combination of EVE with anti-PD-L1 significantly reduced tumor burden compared with the EVE alone treatment, increasing tumor infiltrating lymphocytes (TILs) and the ratio of cytotoxic CD8+ T cells to TILs. The results of the present study demonstrated that anti-PD-L1 treatment enhanced the antitumor effect of EVE in a mouse model, supporting a direct translation of this combination strategy to the clinic for the treatment of RCC.

AB - BACKGROUND AND OBJECTIVE: Acute respiratory failure (ARF) in patients with interstitial lung disease (ILD) is associated with significant morbidity and mortality. Recommended assessment for acute exacerbation (AE) of ILD includes exclusion of secondary causes via fibreoptic bronchoscopy. Our aim is to assess the role of bronchoscopy during ARF-ILD. METHODS: Consecutive ILD patients (2002 2014) hospitalized with ARF who underwent bronchoscopy were included. Baseline demographics, underlying ILD diagnoses and presenting clinical features were reviewed. Characteristics of bronchoscopy including diagnostic findings, management and complications were collated. RESULTS: One hundred and six patients accounted for 119 unique bronchoscopies. Sixteen (13%) were abnormal (12 infections and 4 haemorrhages). Baseline presenting clinical features did not differ between those with and without abnormal findings. About half were performed in an intensive care unit (ICU) (53%), with 25% of bronchoscopies performed in a general floor setting resulting in ICU transfer; 71% of whom resulted in immediate mechanical ventilation. Overall management of ARF in those with positive bronchoscopy findings was similar to those without, resulting in similar in-hospital mortality. CONCLUSION: Bronchoscopy in the clinical assessment of ARF-ILD is often performed with only a 13% yield in this large retrospective cohort. As management and in-hospital mortality were similar, routine diagnostic bronchoscopy in ARF-ILD should be further studied given its low yield and high procedural risk.

AB - Contrary to the simple expectations from Coulomb's law, Weinhold proposed that anions can stabilize each other as metastable dimers, yet experimental evidence for these species and their mutual stabilization is missing. We show that two bisulfate anions can form such dimers, which stabilize each other with self complementary hydrogen bonds, by encapsulation inside a pair of cyanostar macrocycles. The resulting 2:2 complex of the bisulfate homodimer persists across all states of matter, including in solution. The bisulfate dimer's OH???O hydrogen bonding is seen in a 1 H NMR peak at 13.75 ppm, which is consistent with borderline-strong hydrogen bonds.

AB - In ionic liquid crystals, the orthogonal smectic A phase is the most common phase whereas the tilted smectic C phase is rather rare. We present a new study with five novel ionic liquid crystals exhibiting both a smectic A as well as the rare smectic C phase. Two of them have a phenylpyrimidine core whereas the other three are imidazolium azobenzenes. Their phase sequences and tilt angles were studied by polarizing microscopy and their temperature-dependent layer spacing as well as their translational and orientational order parameters were studied by X-ray diffraction. The X-ray tilt angles derived from X-ray studies of the layer contraction and the optically measured tilt angles of the five ionic liquid crystals were compared to obtain their de Vries character. Four of our five mesogens turned out to show de Vries-like behavior with a layer shrinkage that is far less than that expected for conventional materials. These materials can thus be considered as the first de Vries-type materials among ionic liquid crystals.

AB - Highly crystalline graphitic carbon nitride (g-C3 N4 ) with decreased structural imperfections benefits from the suppression of electron-hole recombination, which enhances its hydrogen generation activity. However, producing such g-C3 N4 materials by conventional heating in an electric furnace has proven challenging. Herein, we report on the synthesis of high-quality g-C3 N4 with reduced structural defects by judiciously combining the implementation of melamine cyanuric acid (MCA) supramolecular aggregates and microwave-assisted thermolysis. The g-C3 N4 material produced after optimizing the microwave reaction time can effectively generate H2 under visible-light irradiation. The highest H2 evolution rate achieved was 40.5 MUmol h-1 , which is two times higher than that of a g-C3 N4 sample prepared by thermal polycondensation of the same supramolecular aggregates in an electric furnace. The microwave-assisted thermolysis strategy is simple, rapid, and robust, thereby providing a promising route for the synthesis of high-efficiency g-C3 N4 photocatalysts. PMID- 27712026 TI - De novo autoimmune hepatitis after liver transplantation: A focus on glutathione S-transferase theta 1. AB - De novo autoimmune hepatitis (DAIH) is a rare clinical condition with features that resemble those of autoimmune hepatitis (AIH) in patients undergoing liver transplantation (LT) for nonautoimmune liver disease. The diagnosis of this entity has been based on the presence of biochemical and histological patterns similar to those observed in the primary AIH, although several considerations must be taken into account. The impact of DAIH on graft survival is relevant, and early diagnosis and treatment is associated with a good longterm outcome. Although glutathione S-transferase theta 1 (GSTT1) alloimmune recognition has been shown to be involved in the pathogenesis of DAIH, further studies are necessary to fully determine its pathogenic mechanisms and risk factors. We review the pathophysiology, the most common histological patterns, the treatment strategies, and the longterm outcomes of DAIH after LT with a special focus on GSTT1.

AB - Herein, we report an intramolecular rhodium-catalyzed decarbonylative coupling between cyclobutanones and alkenes that proceeds by C-C activation and provides a distinct approach to a diverse range of saturated bridged cyclopentane derivatives. In this reaction, cyclobutanones serve as cyclopropane surrogates, reacting in a formal (4+2-1) transformation. To demonstrate the efficacy of this method, it was applied in a concise synthesis of the antifungal drug Tolciclate. PMID- 27712027 TI - Clinical practice guidelines for the noninvasive management of low back pain: A systematic review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration. AB - : We conducted a systematic review of guidelines on the management of low back pain (LBP) to assess their methodological quality and guide care. We synthesized guidelines on the management of LBP published from 2005 to 2014 following best evidence synthesis principles. We searched MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane, DARE, National Health Services Economic Evaluation Database, Health Technology Assessment Database, Index to Chiropractic Literature and grey literature. Independent reviewers critically appraised eligible guidelines using AGREE II criteria. We screened 2504 citations; 13 guidelines were eligible for critical appraisal, and 10 had a low risk of bias. According to high-quality guidelines: (1) all patients with acute or chronic LBP should receive education, reassurance and instruction on self-management options; (2) patients with acute LBP should be encouraged to return to activity and may benefit from paracetamol, nonsteroidal anti-inflammatory drugs (NSAIDs), or spinal manipulation; (3) the management of chronic LBP may include exercise, paracetamol or NSAIDs, manual therapy, acupuncture, and multimodal rehabilitation (combined physical and psychological treatment); and (4) patients with lumbar disc herniation with radiculopathy may benefit from spinal manipulation. Ten guidelines were of high methodological quality, but updating and some methodological improvements are needed. Overall, most guidelines target nonspecific LBP and recommend education, staying active/exercise, manual therapy, and paracetamol or NSAIDs as first-line treatments. The recommendation to use paracetamol for acute LBP is challenged by recent evidence and needs to be revisited. SIGNIFICANCE: Most high-quality guidelines recommend education, staying active/exercise, manual therapy and paracetamol/NSAIDs as first-line treatments for LBP. Recommendation of paracetamol for acute LBP is challenged by recent evidence and needs updating. PMID- 27712028 TI - Prediction of suicidal behavior in high risk psychiatric patients using an assessment of acute suicidal state: The suicide crisis inventory. AB - BACKGROUND: We have developed the Suicide Crisis Inventory (SCI) to evaluate the intensity of the Suicidal Crisis Syndrome, an acute state hypothesized to precede suicide attempt. The psychometric properties of the SCI, including predictive validity for suicidal behavior (SB), were assessed. METHODS: Adult psychiatric patients (n = 201) hospitalized for high suicide risk were assessed. Logistic regression models assessed the SCI's predictive validity for SB in the 4-8 weeks following hospital discharge and its incremental predictive validity over traditional risk factors (n = 137, 64% f/u rate). Internal structure, reliability, convergent and discriminant validity, and state versus trait properties were also assessed. RESULTS: The SCI had excellent internal consistency (Cronbach's alpha 0.970). The SCI total score at discharge predicted short-term SB with 64% sensitivity 88% specificity (OR = 13, P = .003) at its optimal cut score. In a test of its incremental predictive validity, SCI total score at discharge improved prediction of SB over traditional risk factors (Chi squared 5.597, P = .024, model P = .001), with AOR 2.02 (P = .030). The SCI admission versus discharge test-retest reliability and score distributions showed it to be an acute state measure. CONCLUSION: The SCI was predictive of future SB in high-risk psychiatric inpatients during the crucial weeks following their hospital discharge. Further validation in diverse patient populations is needed. PMID- 27712029 TI - High serum lipopolysaccharide binding protein is associated with increased mortality in patients with decompensated cirrhosis. AB - BACKGROUND & AIMS: Lipopolysaccharide-binding-protein (LBP) is an acute-phase protein produced by hepatocytes. Changes in LBP are associated with the dynamics of bacterial translocation and intestinal permeability in decompensated cirrhosis (DC). We assessed serum and ascitic-fluid (AF) LBP and examined their association with mortality in patients with DC. METHODS: Eighty-eight consecutive patients (73.9% males) underwent thorough diagnostic investigations for infection. LBP (ng/mL) was assessed in serum (N=88) and AF (n=49) by enzyme-linked-immunosorbent assay and expressed in natural logarithm (ln). RESULTS: Serum lnLBP was higher in 18 patients with overt infection compared to those without (P<.001). Serum and AF lnLBP 13.49 and 12.11 displayed a very good-negative-predictive value of 90% and 95.1% to rule out infection and spontaneous-bacterial-peritonitis (SBP), respectively. LBP was higher in serum than in AF (P<.001). Serum and AF LBP levels showed a positive correlation with surrogate markers of inflammation. Patients without overt infection were prospectively followed up. The 90-day mortality rate was 48% and 24.4% in patients with high (>=13.49) and low (<13.49) lnLBP, respectively, (log rank P=0.045). In univariate Cox regression analysis, neutrophils, LBP, MELD score and CRP were predictive of mortality. However, only high LBP (HR 8.1 95%CI 2.0-31.5, P=0.003) and MELD (HR 1.1 95%CI 1.0-1.2, P=0.002) were predictive of mortality in multivariate analysis. CONCLUSIONS: Serum and AF LBP concentrations showed a high negative-predictive-value to exclude infection and SBP, respectively. High serum LBP was detected in patients without infection at presentation who died during the 90-day-follow-up period. Elevated serum LBP is a marker of short-term mortality in patients without overt bacterial infection. PMID- 27712030 TI - Effectiveness of Pressure Ulcer Prevention Strategies for Adult Patients in Intensive Care Units: A Systematic Review. AB - BACKGROUND: Pressure ulcers are associated with substantial health burden, but could be preventable. Hospital-acquired pressure ulcers (HAPUs) prevention has become a priority for all healthcare settings, as it is considered a sign of quality of care providing. Intensive care unit (ICU) patients are at higher risk for HAPUs development. Despite the availability of published prevention strategies, there is a little evidence about which strategies can be safely integrated into routine standard care and have an impact on HAPUs prevention. AIMS: The aim was to synthesize the best available evidence regarding the effectiveness of single strategies designed to reduce the incidence and prevalence of HAPUs development in ICUs. METHODS: The search strategy was designed to retrieve studies published in English across CINAHL, Medline, Cochrane Central Register of Controlled Trials, Embase, Scopus, and Mednar between 2000 and 2015. All adult ICU participants were aged 18 years or over. This review included randomized controlled trials, quasi-experimental and comparative studies. The studies that were selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical-appraisal instruments. RESULTS: The review included 25 studies, and the meta-analysis revealed a statistically significant effect of a silicon foam dressing strategy in reducing HAPUs incidence (effect size = 4.62; 95% CI: 0.05-0.29; p < .00001, effect size = 4.50; 95% CI: 0.05 0.31; p = .00001, respectively) in critically ill patients. Evidence of the effectiveness of nutrition, skin-care regimen, positioning and repositioning schedule, support surfaces, and the role of education in prevention of HAPUs development in the ICU was limited, which precludes strong conclusions. LINKING EVIDENCE TO ACTION: The review provides an evidence-based guide to future priorities for clinical practice. In particular, a silicone foam dressing has positive impact in reducing sacrum and heel HAPUs incidence in the ICU. PMID- 27712031 TI - Facile and Green Production of Impurity-Free Aqueous Solutions of WS2 Nanosheets by Direct Exfoliation in Water. AB - To obtain 2D materials with large quantity, low cost, and little pollution, liquid-phase exfoliation of their bulk form in water is a particularly fascinating concept. However, the current strategies for water-borne exfoliation exclusively employ stabilizers, such as surfactants, polymers, or inorganic salts, to minimize the extremely high surface energy of these nanosheets and stabilize them by steric repulsion. It is worth noting, however, that the remaining impurities inevitably bring about adverse effects to the ultimate performances of 2D materials. Here, a facile and green route to large-scale production of impurity-free aqueous solutions of WS2 nanosheets is reported by direct exfoliation in water. Crucial parameters such as initial concentration, sonication time, centrifugation speed, and centrifugation time are systematically evaluated to screen out an optimized condition for scaling up. Statistics based on morphological characterization prove that substantial fraction (66%) of the obtained WS2 nanosheets are one to five layers. X-ray diffraction and Raman characterizations reveal a high quality with few, if any, structural distortions. The water-borne exfoliation route opens up new opportunities for easy, clean processing of WS2 -based film devices that may shine in the fields of, e.g., energy storage and functional nanocomposites owing to their excellent electrochemical, mechanical, and thermal properties. PMID- 27712032 TI - Insights into the Impact of Impurities and Non-Stoichiometric Effects on the Electrochemical Performance of Li2 MnSiO4. AB - A series of Li2 MnSiO4 samples with various Li, Mn, and/or Si concentrations are reported to study for the first time the effect of impurities and deviation from ideal stoichiometry on electrochemical behavior. Carbon-coated and nanosized powders are obtained at 600 degrees C and compared with those synthetized at 900 degrees C. Samples are investigated using XRD, SEM, high-resolution TEM, attenuated total reflection infrared spectroscopy and Brunauer-Emmett-Teller surface area to characterize crystal structure, particle size, impurity amount, morphology, and surface area. Electrochemical performance depends on impurities such as MnO as well as crystallite size, surface area, and non-stoichiometric phases, which lead to the formation of additional polymorphs such as Pmnb and P21 /n of Li2 MnSiO4 at low calcination temperatures. A systematic analysis of the main parameters affecting the electrochemical behavior is performed and trends in synthesis are identified. The findings can be applied to optimize different synthesis routes for attaining stoichiometric and phase-pure Pmn21 Li2 MnSiO4 as cathode material for Li-ion batteries.

PMID- 27712034 TI - Delay of insulin initiation in patients with type 2 diabetes mellitus inadequately controlled with oral hypoglycemic agents (analysis of patient- and physician-related factors): A prospective observational DIPP-FACTOR study in Korea. AB - AIMS/INTRODUCTION: To assess the time to initiation of insulin therapy, and concurrently investigate both patient- and physician-related factors associated with delaying insulin therapy in Korean patients with type 2 diabetes uncontrolled by oral hypoglycemic agents (OHAs). MATERIALS AND METHODS: This prospective, observational disease registry study was carried out across 69 centers in Korea. Type 2 diabetes patients who had received two or more OHAs within the past 5 years, had a glycated hemoglobin >=8% in the past 6 months and had not received insulin were included. Data recorded on data collection forms during a 12-month period were analyzed. RESULTS: Of 2168 patients enrolled, 1959 were evaluated and classified as the insulin-initiated or insulin-delayed group. Insulin was prescribed for just 20% of the patients during a 1-year follow-up period, and less than half (44.5%) of the patients who were taking two OHAs started insulin after 6 years. Patient-related factors for delay in insulin initiation included older age, shorter duration of diabetes and lower glycated hemoglobin. Physician-related factors included age (~50 to <60 years), sex (women) and number (<1000) of patients consulted per month. Patient refusal (33.6%) and physicians' concerns of patient non-compliance (26.5%) were the major physician-reported reasons for delaying insulin therapy. Inconvenience of insulin therapy (51.6%) and fear of injection (48.2%) were the major reasons for patient refusal. CONCLUSIONS: Insulin initiation is delayed in patients with type 2 diabetes uncontrolled by two or more OHAs in Korea. Patient- and physician related factors associated with this delay need to be addressed for better diabetes management. PMID- 27712033 TI - Reduced intensity conditioned allograft yields favorable survival for older adults with B-cell acute lymphoblastic leukemia. AB - Older adults with B-cell acute lymphoblastic leukemia (B-ALL) have poor survival. We examined the effectiveness of reduced intensity conditioning (RIC) hematopoietic cell transplant (HCT) in adults with B-ALL age 55 years and older and explored prognostic factors associated with long-term outcomes. Using CIBMTR registry data, we evaluated 273 patients (median age 61, range 55-72) with B-ALL with disease status in CR1 (71%), >CR2 (17%) and Primary Induction Failure (PIF)/Relapse (11%), who underwent RIC HCT between 2001 and 2012 using mostly unrelated donor (59%) or HLA-matched sibling (32%). Among patients with available cytogenetic data, the Philadelphia chromosome (Ph+) was present in 50%. The 3 year cumulative incidences of nonrelapse mortality (NRM) and relapse were 25% (95% confidence intervals (CI): 20-31%) and 47% (95% CI: 41-53%), respectively. Three-year overall survival (OS) was 38% (95% CI: 33-44%). Relapse remained the leading cause of death accounting for 49% of all deaths. In univariate analysis, 3 year risk of NRM was significantly higher with reduced Karnofsky performance status (KPS <90: 34% (95% CI: 25-43%) versus KPS >=90 (18%; 95% CI: 12-24%, P = 0.006). Mortality was increased in older adults (66+ vs. 55-60: Relative Risk [RR] 1.51 95% CI: 1.00-2.29, P = 0.05) and those with advanced disease (RR 2.13; 95% CI: 1.36-3.34, P = 0.001). Survival of patients in CR1 yields 45% (95% CI: 38 52%) at 3 years and no relapse occurred after 2 years. We report promising OS and acceptable NRM using RIC HCT in older patients with B-ALL. Disease status in CR1 and good performance status are associated with improved outcomes. Am. J. Hematol. 92:42-49, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27712036 TI - In vitro evaluation of poly (lactic-co-glycolic acid)/polyisoprene fibers for soft tissue engineering. AB - The polymeric blend of poly (lactic-co-glycolic acid) (PLGA) and polyisoprene (PI) has recently been explored for application as stents for tracheal stenosis and spring for the treatment of craniosynostosis. From the positive results presented in other biomedical applications comes the possibility of investigating the application of this material as scaffold for tissue engineering (TE), acquiring a deeper knowledge about the polymeric blend by exploring a new processing technique while attending to the most fundamental demands of TE scaffolds. PLGA/PI was processed into randomly oriented microfibers through the dripping technique and submitted to physical-chemical and in vitro characterization. The production process of fibers did not show an effect over the polymer's chemical composition, despite the fact that PLGA and PI were observed to be immiscible. Mechanical assays reinforce the suitability of these scaffolds for soft tissue applications. Skeletal muscle cells demonstrated increases in metabolic activity and proliferation to the same levels of the control group. Human dermal fibroblasts didn't show the same behaviour, but presented cell growth with the same development profile as presented in the control group. It is plausible to believe that PLGA/PI fibrous three-dimensional scaffolds are suitable for applications in soft tissue engineering. (c) 2016 Wiley Periodicals, Inc.

AB - OBJECTIVE: To assess whether an oral direct factor Xa inhibitor (DiXaI) anticoagulant drug used at the low end of the recommended dose in people achieves presumed prophylactic plasma concentrations and does not induce bleeding in horses. DESIGN: Experimental study. SETTING: Field study. ANIMALS: Ten healthy adult horses. INTERVENTIONS: A DiXaI was administered at a dose of 0.125 mg/kg every 24 h orally for 4 days. Following a wash-out period of 2 weeks, 8 of 10 horses received daily subcutaneous doses of a low molecular weight heparin (dalteparin) for 4 consecutive days at 50 IU/kg. In both trials, antifactor Xa activity was measured at baseline time and 3 hours after each dose administration. Activated partial thromboplastin time, prothrombin time, hematocrit, erythrocyte agglutination, and platelet aggregation were monitored throughout the study. In addition, an in vitro spiking experiment was performed to demonstrate anticoagulant activity of this DiXaI in horse plasma. MAIN RESULTS: When treated with the DiXaI, this group of horses did not achieve the suggested thromboprophylactic plasma range of antifactor Xa activity (0.1-0.2 IU/mL), except for 1 horse after the first administration of the drug. In contrast, median values of plasma antifactor Xa activity 3 hours after receiving dalteparin were within the prophylactic range (0.16 IU/mL). No hemorrhagic events or erythrocyte agglutination were observed. In vitro addition of this DiXaI caused a concentration-dependent effect in antifactor Xa activity. CONCLUSIONS: At the low end of the recommended dose in people this oral formulation of DiXaI did not reach prophylactic plasma antifactor Xa activity in this group of healthy adult horses. Further studies are warranted in order to establish the prophylactic dose for horses. PMID- 27712037 TI - In vivo cytochrome P450 activity alterations in diabetic nonalcoholic steatohepatitis mice. AB - Nonalcoholic steatohepatitis (NASH) has been identified as a source of significant interindividual variation in drug metabolism. A previous ex vivo study demonstrated significant changes in hepatic Cytochrome P450 (CYP) activity in human NASH. This study evaluated the in vivo activities of multiple CYP isoforms simultaneously in prominent diabetic NASH mouse models. The pharmacokinetics of CYP selective substrates: caffeine, losartan, and omeprazole changed significantly in a diabetic NASH mouse model, indicating attenuation of the activity of Cyp1a2 and Cyp2c29, respectively. Decreased mRNA expression of Cyp1a2 and Cyp2c29, as well as an overall decrease in CYP protein expression, was found in the diabetic NASH mice. Overall, these data suggest that the diabetic NASH model only partially recapitulates the human ex vivo CYP alteration pattern. Therefore, in vivo determination of the effects of NASH on CYP activity should be conducted in human, and more appropriate models are required for future drug metabolism studies in NASH.

AB - Major concerns about donor morbidity and mortality still limit the use of living donor liver transplantation (LDLT) to overcome the organ shortage. The present study assessed donor safety in LDLT in Italy reporting donor postoperative outcomes in 246 living donation procedures performed by 7 transplant centers. Outcomes were evaluated over 2 time periods using the validated Clavien 5-tier grading system, and several clinical variables were analyzed to determine the risk factors for donor morbidity. Different grafts were obtained from the 246 donor procedures (220 right lobe, 10 left lobe, and 16 left lateral segments). The median follow-up after donation was 112 months. There was no donor mortality. One or more complications occurred in 82 (33.3%) donors, and 3 of them had intraoperative complications (1.2%). Regardless of graft type, the rate of major complications (grade >= 3) was 12.6% (31/246). The overall donor morbidity and the rate of major complications did not differ significantly over time: 26 (10.6%) donors required hospital readmission throughout the follow-up period, whereas 5 (2.0%) donors required reoperation. Prolonged operative time (>400 minutes), intraoperative hypotension (systolic < 100 mm Hg), vascular abnormalities, and intraoperative blood loss (>300 mL) were multivariate risk factors for postoperative donor complications. In conclusion, from the standpoint of living donor surgery, a meticulous and well-standardized technique that reduces operative time and prevents blood loss and intraoperative hypotension may reduce the incidence of donor complications. Transparency in reporting results after LDLT is mandatory, and we should continue to strive for zero donor mortality. Liver Transplantation 23 184-193 2017 AASLD.

PMID- 27712041 TI - Functional anatomy of the mammalian sperm flagellum. AB - The eukaryotic flagellum is the organelle responsible for the propulsion of the male gamete in most animals. Without exception, sperm of all mammalian species use a flagellum for swimming. The mammalian sperm has a centrally located 9 + 2 arrangement of microtubule doublets and hundreds of accessory proteins that together constitute an axoneme. However, they also possess several characteristic peri-axonemal structures that make the mammalian sperm tail function differently. These modifications include nine outer dense fibers (ODFs) that are paired with the nine outer microtubule doublets of the axoneme, and are anchored in a structure called the connecting piece located at the base. The presence of the ODFs and connecting piece, and the absence of a basal body, dictate that physical forces generated by the dynein motors are transmitted to the base of the flagellum through the ODFs. Mammalian sperm flagella also possess a mitochondrial and a fibrous sheath that encircle most of the axoneme. These sheaths and the ODFs add mechanical rigidity to the flagellum creating the functional effect of increasing bend wavelength, which requires the entrainment of more dynein motors in the production of a single wave. The sheaths also act as a retinaculum and maintain the integrity of the central axoneme when large bending torques are generated by dynein. Large torque production is crucial to the process of hyperactivation and the unique motility transitions associated with effective fertilizing capacity. Consequently, these specialized anatomical features are essential for the effective interaction of sperm with the female reproductive tract and ovum. (c) 2016 Wiley Periodicals, Inc. PMID- 27712043 TI - Molecular Simulations Bring New Insights into Protoporphyrinogen IX Oxidase/Protoporphyrinogen IX Interaction Modes. AB - Protoporphyrinogen IX oxidase (PPO, EC 1.3.3.4) catalyzes the oxidation of protoporphyrinogen IX (protogen IX) to protoporphyrin IX (proto IX) in the haem/chlorophyll biosynthetic pathway. Although extensive studies of PPO have already afforded many insights into its biological function and its significance to agriculture and medicine, details of the enzymatic mechanism as well as the nature of the specific amino acids involved in substrate binding still remain largely unknown due to the lack of structural information about protogen IX binding to PPO. In this study, we carried out a detailed and systematic investigation on the binding mode of protogen IX in the Nicotiana tabacum PPO (mtPPO) by performing a computational docking followed by molecular simulations, quantum mechanics calculations, and an integrated analysis. The proposed binding mode was consistent with experimental studies, and several potential key residues that have not been investigated in previous studies, such as Thr70, Arg233, Ser235, Ser474 and Lys477, were identified. In addition, we compared the binding modes of protogen IX in mtPPO and Homo sapiens PPO, and found their differences. Considering the low sequence identity and the differences of biochemical properties among the PPOs from various species, the investigation could provide a valuable basis for the design of PPO inhibitors with high potency and species selectivity.

AB - Molecular interaction potential (MIP) maps are a powerful tool to develop structure-activity relationships of a series of compounds. In the present study we have studied the effect of molecular polarization on the description of the toxicity of a series of dioxins and benzofurans using their MIPs. Specifically, we have used principal component analysis in an exploratory way to understand the common structural features that describe the toxicity of these molecules through the analysis of their MIPs and each of their components, i.e.; molecular electrostatic and polarization potentials. Moreover, we have developed a predictive model using PLS that permits to evaluate the toxicity of compounds belonging to any of the families of compounds studied in the present work on the basis of their molecular electrostatic and interaction potentials.

AB - Probiotics may be used to enhance the functionality and nutritional values of fermented sausages. This study aims to evaluate the physicochemical and sensory properties of beef sausages fermented by lactic acid bacteria of Lactobacillus plantarum IIA-2C12 and L. acidophilus IIA-2B4. These strains were isolated from beef cattle and have shown to display probiotic features. While the nutrient contents were not affected by the probiotics, the pH, texture, and color varied among the sausages. Further analysis on fatty acids showed different profiles of saturated (C14:0, C17:0, and C20:0) and unsaturated (C14:1, C18:1n9c, C18:2n6c, and C22:6n3) fatty acids in sausages with probiotics. Gas chromatography-mass spectrometry further revealed some flavor development compounds including acid, alcohols, aldehydes, aromatic, ketones, sulfur, hydrocarbons and terpenes, varied among the sausages. Hedonic test showed no difference in the preference toward aroma, texture, and color for untrained panelists.

AB - The proto-oncogene protein RET is a receptor tyrosine kinase that plays an important role in the development and progress of various human cancers. Currently, targeting RET with small-molecule tyrosine kinase inhibitors (TKIs) has been established as promising therapeutic strategy for thyroid carcinoma (TC). However, two gatekeeper mutations V804M and V804L in RET kinase domain have been frequently observed to cause drug resistance during the targeted therapy, largely limiting the application of reversible TKIs in TC. Here, we described an integrative protocol that combined literature curation, computational analysis, and in vitro kinase assay to systematically investigate the response profile of 9 approved RET TKIs to the two clinical RET gatekeeper mutations. It was revealed that the two mutations exhibit a similar energetic behavior to influence TKI binding, which can moderately decrease competitive inhibitor affinity and modestly increase substrate ATP affinity simultaneously. However, the binding potency of few second-generation kinase inhibitors such as Ponatinib and Alectinib can be improved to overcome the increased ATP affinity, thus restoring their inhibitory activity against the kinase mutants. Subsequently, the established protocol was employed to investigate the response profile of 4 commercially available RET TKIs that are under preclinical or clinical development. Three out of the four TKIs were found to become resistant upon the mutations due to steric hindrance effect introduced by the mutated residues, while the remaining one was moderately sensitized by the mutations since the mutated residues can form additional hydrophobic and van der Waals interactions with the inhibitor.

AB - Multidimensional mass spectrometry interfaces a suitable ionization technique and mass analysis (MS) with fragmentation by tandem mass spectrometry (MS2 ) and an orthogonal online separation method. Separation choices include liquid chromatography (LC) and ion-mobility spectrometry (IMS), in which separation takes place pre-ionization in the solution state or post-ionization in the gas phase, respectively. The MS step provides elemental composition information, while MS2 exploits differences in the bond stabilities of a polymer, yielding connectivity and sequence information. LC conditions can be tuned to separate by polarity, end-group functionality, or hydrodynamic volume, whereas IMS adds selectivity by macromolecular shape and architecture. This Minireview discusses how selected combinations of the MS, MS2 , LC, and IMS dimensions can be applied, together with the appropriate ionization method, to determine the constituents, structures, end groups, sequences, and architectures of a wide variety of homo- and copolymeric materials, including multicomponent blends, supramolecular assemblies, novel hybrid materials, and large cross-linked or nonionizable polymers.

AB - Autonomic activity in neurological and psychiatric disorders is often dysregulated, particularly in the context of attentional behaviors. This suggests that interplay between the autonomic nervous system and aspects of the central nervous system subserving attention may be disrupted in these conditions. Better understanding these interactions and their relationship with individual variation in attentional behaviors could facilitate development of mechanistic biomarkers. We identified brain regions defined by trait-sensitive central-autonomic coupling as a first step in this process. As spontaneous neural activity measured during the resting state is sensitive to phenotypic variability, unconfounded by task performance, we examined whether spontaneous fluctuations in brain activity and an autonomic measure, pupil diameter, were coupled during the resting state, and whether that coupling predicted individual differences in attentional behavior. By employing concurrent pupillometry and fMRI during the resting state, we observed positive coupling in regions comprising cingulo-opercular, default mode, and fronto-parietal networks, as well as negative coupling with visual and sensorimotor regions. Individuals less prone to distractibility in everyday behavior demonstrated stronger positive coupling in cingulo-opercular regions often associated with sympathetic activity. Overall, our results suggest that individuals less prone to distractibility have tighter intrinsic coordination between specific brain areas and autonomic systems, which may enable adaptive autonomic shifts in response to salient environmental cues. These results suggest that incorporating autonomic indices in resting-state studies should be useful in the search for biomarkers for neurological and psychiatric disorders.

AB - INTRODUCTION: Home ventilation (HV) for children is growing rapidly worldwide. The aim was to describe (1) the sociodemographic characteristics of children on HV and (2) the indications for, means and outcome of initiating HV in children from a developing country. METHODOLOGY: This retrospective study included patients sent home on noninvasive or invasive ventilation, over 13 years, by the pediatric respiratory unit in a single center. Children who declined treatment were excluded. RESULTS: Seventy children were initiated on HV: 85.7% on noninvasive ventilation, 14.3% on invasive ventilation. There was about a threefold increase from 2001-2008 (n = 18) to 2009-2014 (n = 52). Median (range) age of initiating HV was 11 (1-169) months and 73% of children were <2 years old. Common indications for HV were respiratory (57.2%), chest/spine anomalies (11.4%), and neuromuscular (10.0%). Fifty-two percent came off their devices with a median (interquartile range) usage duration of 12 (4.8, 21.6) months. Ten children (14.3%) died with one avoidable death. Children with neuromuscular disease were less likely to come off their ventilator (0.0%) compared to children with respiratory disease (62.1%). Forty-one percent of parents bought their equipment, whereas 58.6% borrowed their equipment from the medical social work department and other sources. CONCLUSION: HV in a resource-limited country is possible. Children with respiratory disease made up a significant proportion of those requiring HV and were more likely to be weaned off. The mortality rate was low. The social work department played an important role in facilitating early discharge. Pediatr Pulmonol. 2017;52:500-507. (c) 2016 Wiley Periodicals, Inc.

AB - Removal of excess amount of hydrogen in a catalytic route is a safety measure to be implemented in fuel cell technologies and in nuclear power plants. Hydrogen and oxygen activation are crucial steps for hydrogen combustion that can be achieved by modifying supports with suitable noble metals. In the present study, Pt- and Pd-substituted Co3O4-ZrO2 (CZ) were synthesized using PEG-assisted sonochemical synthesis. Ionic states of Pt and Pd in CZ supports were analyzed by X-ray photoelectron spectroscopy. Pd and Pt improved H2 and O2 activation extensively, which reduced the temperature of 50% conversion (T50%) to 33 degrees C compared with the support (CZ). The activation energy of PdCZ catalyst was decreased by more than 2 folds (13.4 +/- 1.2 kJ mol-1) compared with CZ (34.3 +/- 2.3 kJ mol-1). The effect of oxygen vacancies in the reaction mechanism is found to be insignificant with Pt- and Pd-substituted CZ supports. However, oxygen vacancies play an important role when CZ alone was used as catalyst. The importance of hydrogen and oxygen activation as well as the oxygen vacancies in mechanism was studied by H2-TPD, H2-TPR, and in situ FTIR spectroscopy.

AB - In the brain and central nervous system, dopamine plays a crucial role as a neurotransmitter or a local chemical messenger for interneuronal communication. Dopamine is associated with renal, hormonal, and cardiovascular systems. Additionally, dopamine dysfunction is known to cause serious illnesses, such as Parkinson's disease and Alzheimer's disease. Therefore, dopamine detection is essential for medical diagnosis and disease prevention and requires a novel strategy with high sensitivity and selectivity and a rapid response. Herein, we present a novel human dopamine receptor (hDRD1)-conjugated multidimensional conducting polymer nanofiber (NF) membrane for the selective and sensitive detection of dopamine. The membrane, which consists of multidimensional carboxylated poly(3,4-ethylenedioxythiophene) (MCPEDOT) NFs with nanorods, is used as a transistor in a liquid-ion gated field-effect transistor (FET)-based biosensor. Interestingly, hDRD1 is first expressed in Escherichia coli before it is immobilized onto the MCPEDOT NF. The hDRD1-MCPEDOT NF-based FET exhibits a rapid real-time response (<2 s) with high dopamine selectivity and sensitivity performance (approximately 100 fM). Furthermore, this FET device can be integrated into a poly(dimethylsiloxane)-based microfluidic system and also can retain its high performance in the integrated system, which results in the generation of large-scale dopamine biosensors with a novel geometry. PMID- 27712052 TI - Antibacterial Adhesion of Poly(methyl methacrylate) Modified by Borneol Acrylate. AB - Poly(methyl methacrylate) (PMMA) is a widely used biomaterial. But there is still a challenge facing its unwanted bacterial adhesion because the subsequent biofilm formation usually leads to failure of related implants. Herein, we present a borneol-modified PMMA based on a facile and effective stereochemical strategy, generating antibacterial copolymer named as P(MMA-co-BA). It was synthesized by free radical polymerization and studied with different ratio between methyl methacrylate (MMA) and borneol acrylate (BA) monomers. NMR, GPC, and EA, etc., were used to confirm their chemical features. Their films were challenged with Escherichia coli (Gram-negative) and Bacillus subtilis (Gram-positive), showing a BA content dependent antibacterial performance. The minimum effective dose should be 10%. Then in vivo subcutaneous implantations in mice demonstrated their biocompatibilities through routine histotomy and HE staining. Therefore, P(MMA-co BA)s not only exhibited their unique antibacterial character but also suggested a potential for the safe usage of borneol-modified PMMA frame and devices for further implantation.

AB - The methylation status of multiplexed methylcytosine sites can be simultaneously monitored by ligation-depended PCR assay. The ability of quantitative detection of multiplexed sites in one PCR reaction makes it a good choice for detecting methylation at both CpG and non-CpG sites for research and diagnosis of disease compared with others. The assay can determine as low as 20 aM methylated DNA and has been successfully applied to the genomic DNA sample derived from cancer cell lines.

AB - Bioethanol as an alternative fuel is widely used as a substitute for gasoline and also in gasoline direct injection (GDI) vehicles, which are quickly replacing traditional port-fuel injection (PFI) vehicles. Better fuel efficiency and increased engine power are reported advantages of GDI vehicles. However, increased emissions of soot-like nanoparticles are also associated with GDI technology with yet unknown health impacts. In this study, we compare emissions of a flex-fuel Euro-5 GDI vehicle operated with gasoline (E0) and two ethanol/gasoline blends (E10 and E85) under transient and steady driving conditions and report effects on particle, polycyclic aromatic hydrocarbon (PAH), and alkyl- and nitro-PAH emissions and assess their genotoxic potential. Particle number emissions when operating the vehicle in the hWLTC (hot started worldwide harmonized light-duty vehicle test cycle) with E10 and E85 were lowered by 97 and 96% compared with that of E0. CO emissions dropped by 81 and 87%, while CO2 emissions were reduced by 13 and 17%. Emissions of selected PAHs were lowered by 67-96% with E10 and by 82-96% with E85, and the genotoxic potentials dropped by 72 and 83%, respectively. Ethanol blending appears to reduce genotoxic emissions on this specific flex-fuel GDI vehicle; however, other GDI vehicle types should be analyzed. PMID- 27712056 TI - Size-Dependent Fullerene-Fullerene Interactions in Water: A Molecular Dynamics Study. AB - Nested fullerenes display a range of unique properties influenced by their size and shape. In this paper, the size- and shape-dependent aggregation of nested fullerenes in water is studied using explicit solvent molecular dynamic simulations. It is shown that water forms a layered structure near the surface of the particle, with the density of interfacial water increasing with increasing particle size. Meanwhile, water molecules near the extended facets of large nested fullerenes are unable to maintain their hydrogen bonding network, leading to a shape and size mediated structuring of surrounding waters. These distortions affect the overall association kinetics of particles in water with spherically shaped particles transitioning quickly into contact, while larger fullerenes, characterized by a lower sphericity, cluster at a much slower rate. PMID- 27712055 TI - Discovery and Characterization of Allosteric WNK Kinase Inhibitors. AB - Protein kinases are known for their highly conserved adenosine triphosphate (ATP) binding site, rendering the discovery of selective inhibitors a major challenge. In theory, allosteric inhibitors can achieve high selectivity by targeting less conserved regions of the kinases, often with an added benefit of retaining efficacy under high physiological ATP concentration. Although often overlooked in favor of ATP-site directed approaches, performing a screen at high ATP concentration or stringent hit triaging with high ATP concentration offers conceptually simple methods of identifying inhibitors that bind outside the ATP pocket. Here, we applied the latter approach to the With-No-Lysine (K) (WNK) kinases to discover lead molecules for a next-generation antihypertensive that requires a stringent safety profile. This strategy yielded several ATP noncompetitive WNK1-4 kinase inhibitors, the optimization of which enabled cocrystallization with WNK1, revealing an allosteric binding mode consistent with the observed exquisite specificity for WNK1-4 kinases. The optimized compound inhibited rubidium uptake by sodium chloride cotransporter 1 (NKCC1) in HT29 cells, consistent with the reported physiology of WNK kinases in renal electrolyte handling. PMID- 27712058 TI - Inhibition and Promotion of Heat-Induced Gelation of Whey Proteins in the Presence of Calcium by Addition of Sodium Caseinate. AB - Heat-induced aggregation and gelation of aqueous solutions of whey protein isolate (WPI) in the presence of sodium caseinate (SC) and CaCl2 was studied at pH 6.6. The effect of adding SC (0-100 g/L) on the structure of the aggregates and the gels was investigated by light scattering and confocal laser scanning microscopy at different CaCl2 concentration ([CaCl2] = 0-30 mM). The gelation process was studied by oscillatory shear rheology. At the whey protein concentrations studied here (34 and 60 g/L), no gels were formed in the absence of CaCl2 and SC. However, WPI solutions gelled above a critical CaCl2 concentration that increased with increasing SC concentration. In the absence of CaCl2, WPI gels were formed only above a critical SC concentration. The critical SC concentration needed to induce WPI gelation decreased weakly when CaCl2 was added. In an intermediate range of CaCl2 concentrations, gels were formed both at low and high SC concentrations, but not at intermediate SC concentrations. Finally, at high CaCl2 concentrations gels were formed at all SC concentrations. The gelation rate and the gel structure of the gels formed at low and high casein concentrations were very different. The effect of SC on the thermal gelation of WPI was interpreted by competition for Ca2+, a chaperon effect, and microphase separation.

AB - Nanoscience and nanotechnology are poised to contribute to a wide range of fields, from health and medicine to electronics, energy, security, and more. These contributions come both directly in the form of new materials, interfaces, tools, and even properties as well as indirectly by connecting fields together. We celebrate how far we have come, and here, we look at what is to come over the next decade that will leverage the strong and growing base that we have built in nanoscience and nanotechnology. PMID- 27712057 TI - Selective Uptake of Alkaline Earth Metals by Cyanobacteria Forming Intracellular Carbonates. AB - The uptakes of calcium (Ca), strontium (Sr), and barium (Ba) by two cyanobacterial strains, Cyanothece sp. PCC7425 and Gloeomargarita lithophora, both forming intracellular carbonates, were investigated in laboratory cultures. In the culture medium BG-11 amended with 250 MUM Ca and 50 or 250 MUM Sr and Ba, G. lithophora accumulated first Ba, then Sr, and finally Ca. Sr and Ba were completely accumulated by G. lithophora cells at rates between 0.02 and 0.10 fmol h-1 cell-1 and down to extracellular concentrations below the detection limits of inductively coupled plasma atomic emission spectroscopy. Accumulation of Sr and Ba did not affect the growth rate of the strain. This sequential accumulation occurred mostly intracellularly within polyphosphate and carbonate granules and resulted in the formation of core-shell structures in carbonates. In contrast, Cyanothece sp. PCC7425 showed neither a preferential accumulation of heavier alkaline earth metals nor core-shell structures in the carbonates. This indicated that fractionation between alkaline earth metals was not inherent to intracellularly calcifying cyanobacteria but was likely a genetically based trait of G. lithophora. Overall, the capability of G. lithophora to sequester preferentially Sr and Ba at high rates may be of considerable interest for designing new remediation strategies and better understanding the geochemical cycles of these elements. PMID- 27712060 TI - Composition by LC-MS/MS of New Carotenoid Esters in Mango and Citrus. AB - Interest in the composition of carotenoid esters of fruits is growing because esterification may affect their bioavailability. Thus, the aim was to provide a detailed identification of carotenoid esters in citrus and mango. Orange cv. 'Valencia' and cv. 'Pera' presented 9 free carotenoids, 38 monoesters, and 60 diesters. Violaxanthin and luteoxanthin derivatives were the major ones, followed by antheraxanthin, lutein, zeaxanthin, beta-cryptoxanthin, and zeinoxanthin esters, many of them reported for the first time in orange pulp. The carotenoid ester composition of tangor cv. 'Murcott', reported for the first time, showed 8 free carotenoids, 34 monoesters, and 33 diesters, with beta-cryptoxanthin esters as major compounds, followed by violaxanthin and zeaxanthin esters. In citrus, carotenoids were acylated mainly with capric, lauric, myristic, myristoleic, palmitic, palmitoleic, and oleic acids. In mango, 5 free carotenoids, 2 monoesters, and 19 diesters were identified, from which many violaxanthin and neoxanthin esters were reported for the first time. PMID- 27712061 TI - Simultaneous Microcystis Algicidal and Microcystin Degrading Capability by a Single Acinetobacter Bacterial Strain. AB - Measures for removal of toxic harmful algal blooms often cause lysis of algal cells and release of microcystins (MCs). In this study, Acinetobacter sp. CMDB-2 that exhibits distinct algal lysing activity and MCs degradation capability was isolated. The physiological response and morphological characteristics of toxin producing Microcystis aeruginosa, the dynamics of intra- and extracellular MC-LR concentration were studied in an algal/bacterial cocultured system. The results demonstrated that Acinetobacter sp. CMDB-2 caused thorough decomposition of algal cells and impairment of photosynthesis within 24 h. Enhanced algal lysis and MC LR release appeared with increasing bacterial density from 1 * 103 to 1 * 107 cells/mL; however, the MC-LR was reduced by nearly 94% within 14 h irrespective of bacterial density. Measurement of extracellular and intracellular MC-LR revealed that the toxin was decreased by 92% in bacterial cell incubated systems relative to control and bacterial cell-free filtrate systems. The results confirmed that the bacterial metabolite caused 92% lysis of Microcystis aeruginosa cells, whereas the bacterial cells were responsible for approximately 91% reduction of MC-LR. The joint efforts of the bacterium and its metabolite accomplished the sustainable removal of algae and MC-LR. This is the first report of a single bacterial strain that achieves these dual actions. PMID- 27712062 TI - Dual Detection System for Simultaneous Measurement of Intracellular Fluorescent Markers and Cellular Secretion. AB - Glucose-stimulated insulin secretion from pancreatic beta-cells within islets of Langerhans plays a critical role in maintaining glucose homeostasis. Although this process is essential for maintaining euglycemia, the underlying intracellular mechanisms that control it are still unclear. To allow simultaneous correlation between intracellular signal transduction events and extracellular secretion, an analytical system was developed that integrates fluorescence imaging of intracellular probes with high-speed automated insulin immunoassays. As a demonstration of the system, intracellular [Ca2+] ([Ca2+]i) was measured by imaging Fura-2 fluorescence simultaneously with insulin secretion from islets exposed to elevated glucose levels. Both [Ca2+]i and insulin were oscillatory during application of 10 mM glucose with temporal and quantitative profiles similar to what has been observed elsewhere. In previous work, sinusoidal glucose levels have been used to test the entrainment of islets while monitoring either [Ca2+]i or insulin levels; using this newly developed system, we show unambiguously that oscillations of both [Ca2+]i and insulin release are entrained to oscillatory glucose levels and that the temporal correlation of these are maintained throughout the experiment. It is expected that the developed analytical system can be expanded to investigate a number of other intracellular messengers in islets or other stimulus-secretion pathways in different cells.

AB - We report full quantum integral and differential cross sections and rate constants for the 17O + 32O2 collision, possibly reactive, process. This constitutes the first quantum scattering study of the 17O16O16O system. We emphasize the comparison with the 18O + 32O2 collision in close connection to the mass independent fractionation (thereafter refered to as MIF) puzzle for ozone in atmospheric chemistry. We find similar general trends in the cross sections and rate constants for both rare isotopes, but we note some singular behaviors peculiar to the use of 17O isotope, particularly at the lowest collision energies. PMID- 27712064 TI - Shape-Controlled Synthesis of All-Inorganic CsPbBr3 Perovskite Nanocrystals with Bright Blue Emission. AB - We developed a colloidal synthesis of CsPbBr3 perovskite nanocrystals (NCs) at a relative low temperature (90 degrees C) for the bright blue emission which differs from the original green emission (~510 nm) of CsPbBr3 nanocubes as reported previously. Shapes of the obtained CsPbBr3 NCs can be systematically engineered into single and lamellar-structured 0D quantum dots, as well as face to-face stacking 2D nanoplatelets and flat-lying 2D nanosheets via tuning the amounts of oleic acid (OA) and oleylamine (OM). They exhibit sharp excitonic PL emissions at 453, 472, 449, and 452 nm, respectively. The large blue shift relative to the emission of CsPbBr3 bulk crystal can be ascribed to the strong quantum confinement effects of these various nanoshapes. PL decay lifetimes are measured, ranging from several to tens of nanoseconds, which infers the higher ratio of exciton radiative recombination to the nonradiative trappers in the obtained CsPbBr3 NCs. These shape-controlled CsPbBr3 perovskite NCs with the bright blue emission will be widely used in optoelectronic applications, especially in blue LEDs which still lag behind compared to the better developed red and green LEDs.

AB - Meta-C-H amination and meta-C-H alkynylation using a modified norbornene (methyl bicyclo[2.2.1]hept-2-ene-2-carboxylate) as a transient mediator has been developed for the first time. Both the identification of a mono-protected 3-amino 2-hydroxypyridine/pyridone type ligand and the use of methyl bicyclo[2.2.1]hept-2 ene-2-carboxylate as the mediator are crucial for realizing these two unprecedented meta-C-H transformations. A variety of substrates are compatible with both meta-C-H amination and meta-C-H alkynylation. Amination and alkynylation of heterocyclic substrates including indole, indoline, and indazole afford the desired products in moderate to high yields. PMID- 27712066 TI - Characterization of Key Odorants Causing a Fusty/Musty Off-Flavor in Native Cold Pressed Rapeseed Oil by Means of the Sensomics Approach. AB - The sensomics approach was used to clarify the formation of the fusty/musty off flavor of native cold-pressed rapeseed oil. A "positive control" (PC) showing the desired sensory attributes and an oil eliciting a fusty/musty off-flavor (OF) were analyzed. Comparative aroma extract dilution analysis (cAEDA), identification experiments, quantitation by stable isotope dilution assays (SIDAs), calculation of odor activity values (OAVs), and aroma recombination resulted in 11 odorants with an OAV >= 1 in PC. Main differences between both oils were obtained for compounds caused by microbial influence revealing significantly higher concentrations in OF, e.g., for ethyl 2-methylbutanoate, 2 methoxyphenol, 3-hydroxy-4,5-dimethylfuran-2(5H)-one (sotolon), 2- and 3 methylbutanoic acid, and 4-methylphenol. Comparison of the key odorants in OF with those of the rapeseeds (OFS), from which it was pressed, showed the same 18 compounds proving that the grade of the seeds and their storage conditions are important criteria for the quality of the final oil. Finally, a further 7 native cold-pressed rapeseed oils, eliciting the same sensory defect, were analyzed to confirm aroma-active marker compounds responsible for the fusty/musty off-flavor. PMID- 27712067 TI - Hollow Nano- and Microstructures as Catalysts. AB - Catalysis is at the core of almost every established and emerging chemical process and also plays a central role in the quest for novel technologies for the sustainable production and conversion of energy. Particularly since the early 2000s, a great surge of interest exists in the design and application of micro- and nanometer-sized materials with hollow interiors as solid catalysts. This review provides an updated and critical survey of the ever-expanding material architectures and applications of hollow structures in all branches of catalysis, including bio-, electro-, and photocatalysis. First, the main synthesis strategies toward hollow materials are succinctly summarized, with emphasis on the (regioselective) incorporation of various types of catalytic functionalities within their different subunits. The principles underlying the scientific and technological interest in hollow materials as solid catalysts, or catalyst carriers, are then comprehensively reviewed. Aspects covered include the stabilization of catalysts by encapsulation, the introduction of molecular sieving or stimuli-responsive "auxiliary" functionalities, as well as the single particle, spatial compartmentalization of various catalytic functions to create multifunctional (bio)catalysts. Examples are also given on the applications which hollow structures find in the emerging fields of electro- and photocatalysis, particularly in the context of the sustainable production of chemical energy carriers. Finally, a critical perspective is provided on the plausible evolution lines for this thriving scientific field, as well as the main practical challenges relevant to the reproducible and scalable synthesis and utilization of hollow micro- and nanostructures as solid catalysts. PMID- 27712068 TI - Stable Graphene-Isolated-Au-Nanocrystal for Accurate and Rapid Surface Enhancement Raman Scattering Analysis. AB - Various interferences from measurement conditions and substrate inhomogeneity are well-known confounding factors for poor reproducibility, which is a challenge in surface-enhanced Raman scattering (SERS) quantification. To address these issues, novel substrates and versatile internal standards have been designed and the repeatability is improved to some degree. However, these internal standards are either complex or unstable enough to resist harsh environments such as acid and oxidation. Graphene-isolated-Au-nanocrystal (GIAN) has unique properties and been applied for cell multimodal imaging and chemotherapy but not for SERS quantification analysis yet. Herein, we chose GIANs to improve the accuracy of SERS analysis. GIAN integrates the SERS effect and internal standard into a simple nanoparticle and is proved to be an ideal platform for SERS analysis given its superior properties: (1) chemical stability, it remains stable in strong acid and oxidation, even mimic bioenvironment; (2) a simple core-shell structure, with a thin graphitic shell which is not only a protector that avoiding inner Au catalysis unnecessary reaction but also an internal standard to eliminate the interference during the Raman detections; (3) the big-Pi structure can absorb target molecule thus achieve an enrichment effect and quench background fluorescence. Laser power, focus, and substrate fluctuations as well as coexist substance interferences were investigated and the accuracy was improved greatly with the introduction of 2D band internal standard in Raman silent region with less background. Moreover, GIAN was applied for crystal violet determination directly on fish muscle and scale, which was rapid and convenient without complex extraction process. All these results indicate GIAN is an optimum choice for SERS analysis in complex systems. PMID- 27712069 TI - Stable Disk Assemblies of a Tobacco Mosaic Virus Mutant as Nanoscale Scaffolds for Applications in Drug Delivery. AB - Current approaches to nanoscale therapeutic delivery rely on the attachment of a drug of interest to a nanomaterial scaffold that is capable of releasing the drug selectively in a tumor environment. One class of nanocarriers receiving significant attention is protein nanomaterials, which are biodegradable and homogeneous in morphology and can be equipped with multiple functional handles for drug attachment. Although most protein-based nanocarriers are spherical in morphology, recent research has revealed that nonspherical nanomaterials may have favorable tumor uptake in comparison to their spherical counterparts. It is therefore important to expand the number of nonspherical protein-based nanocarriers that are available. Herein, we report the development of a self assembling nanoscale disk derived from a double arginine mutant of recombinantly expressed tobacco mosaic virus coat protein (RR-TMV). RR-TMV disks display highly stable double-disk assembly states. These RR-TMV disks were functionalized with the chemotherapy drug doxorubicin (DOX) and further modified with polyethylene glycol (PEG) for improved solubility. RR-TMVDOX-PEG displayed cytotoxic properties similar to those of DOX alone when incubated with U87MG glioblastoma cells, but unmodified RR-TMV did not cause any cytotoxicity. The RR-TMV disk assembly represents a promising protein-based nanomaterial for applications in drug delivery. PMID- 27712070 TI - Molecular Dynamics Simulations Predict the Pathways via Which Pristine Fullerenes Penetrate Bacterial Membranes. AB - Carbon fullerenes are emerging as effective devices for different biomedical applications, including the transportation of nanosized drugs and extraction of harmful oxidants and radicals. It has been proposed that fullerenes could be used as novel antibacterial agents, given the realization that the nanoparticles can kill pathogenic Gram-negative bacteria. To explore this at the molecular level, we simulated C60 fullerenes with bacterial membranes using the coarse-grain molecular dynamics Martini force field. We found that pristine C60 has a limited tendency to penetrate (incomplete core) Re mutant lipopolysaccharide (LPS) leaflets, but the translocation of C60 fullerenes into (complete core) Ra mutant LPS leaflets is not thermodynamically favored. Moreover, we showed that the permeability of the Re LPS bilayers depends sensitively on the system temperature, charge of ambient ions, and prevalence of palmitoyloleoylphosphoethanolamine (POPE) defect domains. The different permeabilities are rationalized in terms of transitory head group pore formation, which underpins the translocation of C60 into the lipid core. The Re LPS lipids readily form transient micropores when they are linked with monovalent cations or when they are heated to a high temperature. POPE lipids are shown to be particularly adept at forming these transient surface cavities, and their inclusion into Re LPS membranes facilitates the formation of particularly large pores that are tunneled by C60 aggregates of a significant size (~5 nm wide). After insertion into the lipid core, the aggregates dissociate, and the disbanded nanoparticles migrate to the interface between separate POPE and LPS domains, where they weaken the boundaries between the coexisting lipid fractions and thereby promote lipid mixing. PMID- 27712071 TI - Tetraazacalix[2]arence[2]triazine Coated Fe3O4/SiO2 Magnetic Nanoparticles for Simultaneous Dispersive Solid Phase Extraction and Determination of Trace Multitarget Analytes. AB - To satisfy the requirement of simultaneous extraction and characterization of diverse kinds of multitarget analytes, the preparation, characterization, and application of a novel tetraazacalix[2]arene[2]triazine (TCT) coated magnetic nanoparticle (TCT MNP) adsorbent are presented in this paper. TCT assembles two benzene rings and two triazines with nitrogen cross-bridging links, which exhibits a unique structural framework and versatile recognition features based on the multiple recognition sites. These include pi electron stacking, charge transfer, hydrogen bonding, and ion-exchange. TCT MNPs acted as a dispersive SPE adsorbent showing strong interaction with and adsorption of polycyclic aromatic hydrocarbons (PAHs), nitroaromatics, and heavy metal ions. The dispersive magnetic nanoparticle solid phase extraction (d-MNSPE) strategy with the simultaneous extraction and stepwise elution (SESE) procedure was designed and optimized for the five PAHs (phenanthrene, anthracene, pyrene, chrysene, and benzo(a)pyrene), six nitroaromatics (4-nitrotoluene, 2,4-dinitrotoluene, 2,4,6 trinitrotoluene, 4-nitrophenol, 2,4-dinitrophenol, and 2,4,6-trinitrophenol), and four metal ions (Cu, Zn, Mn, Cd) in aqueous samples. Due to the high stability, desirable durability, larger saturation magnetization, reuse and distinct enrichment capacity of TCT MNPs, the d-MNSPE method with the SESE strategy provided high recovery (>90%) and good precision (relative standard deviations, RSD < 10%). Coupled with the commonly used HPLC-fluorescence detection, HPLC-UV detection, and atomic absorption spectrometry, these trace probes in tap water, river water, and lake water were determined with very low detection limits, in the range of 0.09-0.15 pg mL-1 for PAHs, 6-11 pg mL-1 for nitroaromatics, and 17 53 pg mL-1 for metal ions after being enriched by the d-MNSPE. The determination of trace PAHs in urine samples from smokers and nonsmokers was successfully carried out with this method, which implied that the versatile TCT MNPs and the robust method together represent a significant potential application in the analysis of body fluids and disease markers. Such methods for accurate quantification of trace components in water are very valuable as they fulfill an unmet need in environmental and medicinal chemistry. PMID- 27712072 TI - Computational Study of Reduction Potentials of Th4+ Compounds and Hydrolysis of ThO2(H2O)n, n = 1, 2, 4. AB - The stability of Th4+ to reduction in water is studied by DFT methods. The standard reduction potential (SRP) of homoleptic complexes including Th(H2O)94+, Th(H2O)104+, Th(NO3)4, Th(NO2)62-, Th(NO3)62-, Th(COT)2, Th(acac)4, ThCp4, ThF4, and ThCl4 have been investigated. The values vary widely (from -3.50 V for Th(OH)4 to -0.62 V for Th(NO3)4 depending on whether the ligands are redox active (noninnocent) or not. Several additional topics of thorium chemistry are explored, including the hydrolysis mechanism of ThO2(H2O)n, n = 1, 2, 4, and the solution phase nonzero dipole moment of ThCp4. Dinuclear complexes are also characterized, including Th2O4, Th2O2(OH)4, Th2O2(H2O)8, Th2(OH)8(H2O)4, and Th2(OH)2(NO3)6(H2O)4 and condensed thorium complexes as [Th4(OH)6(H2O)12]10+ and [Th6(OH)14(H2O)12]10+. For the Th2(OH)2(NO3)6(H2O)4 dinuclear complex, the first SRP is -0.82 V and the second is 1.59 V. The first SRP corresponds to the reduction of the ligand NO3-, and the second SRP corresponds to dissociative electron transfer to the NO32- ligand. The calculated formation constant of Th(EDTA)(H2O)4 is in reasonable agreement with experiment. The different stereochemistries of the bidentate ligands NO2-, NO3-, and acetylacetonate (acac) around the thorium center have very similar stabilities.

AB - Translocation of substrates across the cell membrane by adenosine 5'-triphosphate (ATP)-binding cassette (ABC) transporters depends on the energy provided by ATP hydrolysis within the nucleotide-binding domains (NBDs). However, the detailed mechanism remains unclear. In this study, we focused on maltose transporter NBDs (MalK2) and performed a quantum mechanical/molecular mechanical (QM/MM) well tempered metadynamics simulation to address this issue. We explored the free energy profile along an assigned collective variable. As a result, it was determined that the activation free energy is approximately 10.5 kcal/mol, and the reaction released approximately 3.8 kcal/mol of free energy, indicating that the reaction of interest is a one-step exothermic reaction. The dissociation of the ATP gamma-phosphate seems to be the rate-limiting step, which supports the so called dissociative model. Moreover, Glu159, located in the Walker B motif, acts as a base to abstract the proton from the lytic water, but is not the catalytic base, which corresponds to an atypical general base catalysis model. We also observed two interesting proton transfers: transfer from the His192 epsilon position nitrogen to the dissociated inorganic phosphate, Pi, and transfer from the Lys42 side chain to adenosine 5'-diphosphate beta-phosphate. These proton transfers would stabilize the posthydrolysis state. Our study provides significant insight into the ATP hydrolysis mechanism in MalK2 from a dynamical viewpoint, and this insight would be applicable to other ABC transporters.

AB - The stability dilemma and limited tumor penetration of nanocarriers in cancer chemotherapy remain two predominant challenges for their successful clinical translation. Herein, the pH-sensitive fluorocarbon-functionalized nanocarriers (SFNs) with a tumor-homing and penetrating peptide iRGD are reported to overcome the stability dilemma and enhance tumor accumulation and penetration in an orthotopic breast cancer. The highly stable SFNs with a low critical association concentration provide a safe and spacious harbor for hydrophobic drugs. Furthermore, the stimulus-responsive evaluation and in vitro drug release study show that the SFNs can balance intracellular dissociation for drug release and extracellular stability in the blood circulation. Additionally, the tumor penetration capacity has been dramatically enhanced in 3D multicellular spheroids, effectively affecting cells far from the periphery. This can be ascribed to the coadministration of iRGD having tumor-penetrating ability and fluorocarbon chains having good cell membrane permeability. The combination of SFNs and iRGD is a viable approach to assist drugs' effective accumulation in primary and metastasized tumor sites, significantly inhibiting the breast tumor growth and curbing lung and liver metastases in an orthotopic-tumor-bearing mouse model. Taken together, this pH-sensitive fluorinated nanosystem having excellent stability and tumor accumulation and penetration properties paves the way to combat cancer. PMID- 27712075 TI - Ferromagnetic/Nonmagnetic Nanostructures for the Electrical Measurement of the Spin Hall Effect. AB - Spin-orbitronics is based on the ability of spin-orbit interactions to achieve the conversion between charge currents and pure spin currents. As the precise evaluation of the conversion efficiency becomes a crucial issue, the need for straightforward ways to observe this conversion has emerged as one of the main challenges in spintronics. Here, we propose a simple device, akin to the ferromagnetic/nonmagnetic bilayers used in most spin-orbit torques experiments, and consisting of a spin Hall effect wire connected to two transverse ferromagnetic electrodes. We show that this system allows probing electrically the direct and inverse conversion in a spin Hall effect system and measuring both the spin Hall angle and the spin diffusion length. By applying this method to several spin Hall effect materials (Pt, Pd, Au, Ta, W), we show that it represents a promising tool for the metrology of spin-orbit materials. PMID- 27712076 TI - Nanoscale Coordination Polymers Codeliver Carboplatin and Gemcitabine for Highly Effective Treatment of Platinum-Resistant Ovarian Cancer. AB - Due to the ability of ovarian cancer (OCa) to acquire drug resistance, it has been difficult to develop efficient and safe chemotherapy for OCa. Here, we examined the therapeutic use of a new self-assembled core-shell nanoscale coordination polymer nanoparticle (NCP-Carbo/GMP) that delivers high loadings of carboplatin (28.0 +/- 2.6 wt %) and gemcitabine monophosphate (8.6 +/- 1.5 wt %). A strong synergistic effect was observed between carboplatin and gemcitabine against platinum-resistant OCa cells, SKOV-3 and A2780/CDPP, in vitro. The coadministration of carboplatin and gemcitabine in the NCP led to prolonged blood circulation half-life (11.8 +/- 4.8 h) and improved tumor uptake of the drugs (10.2 +/- 4.4% ID/g at 24 h), resulting in 71% regression and 80% growth inhibition of SKOV-3 and A2780/CDDP tumors, respectively. Our findings demonstrate that NCP particles provide great potential for the codelivery of multiple chemotherapeutics for treating drug-resistant cancer. PMID- 27712077 TI - PEGylation of Reduced Graphene Oxide Induces Toxicity in Cells of the Blood-Brain Barrier: An in Vitro and in Vivo Study. AB - Polyethylene glycol (PEG) coating has been frequently used to improve the pharmacokinetic behavior of nanoparticles. Studies that contribute to better unravel the effects of PEGylation on the toxicity of nanoparticle formulation are therefore highly relevant. In the present study, reduced graphene oxide (rGO) was functionalized with PEG, and its effects on key components of the blood-brain barrier, such as astrocytes and endothelial cells, were analyzed in culture and in an in vivo rat model. The in vitro studies demonstrated concentration dependent toxicity. The highest concentration (100 MUg/mL) of non-PEGylated rGO had a lower toxic influence on cell viability in primary cultures of astrocytes and rat brain endothelial cells, while PEGylated rGO induced deleterious effects and cell death. We assessed hippocampal BBB integrity in vivo by evaluating astrocyte activation and the expression of the endothelial tight and adherens junctions proteins. From 1 h to 7 days post-rGO-PEG systemic injection, a notable and progressive down-regulation of protein markers of astrocytes (GFAP, connexin 43), the endothelial tight (occludin), and adherens (beta-catenin) junctions and basal lamina (laminin) were observed. The formation of intracellular reactive oxygen species demonstrated by increases in the enzymatic antioxidant system in the PEGylated rGO samples was indicative of oxidative stress-mediated damage. Under the experimental conditions and design of the present study the PEGylation of rGO did not improve interaction with components of the blood-brain barrier. In contrast, the attachment of PEG to rGO induced deleterious effects in comparison with the effects caused by non-PEGylated rGO. PMID- 27712078 TI - Extracellular Proteome and Citrullinome of the Oral Pathogen Porphyromonas gingivalis. AB - Porphyromonas gingivalis is an oral pathogen associated with the inflammatory disease periodontitis. Periodontitis and P. gingivalis have been associated with rheumatoid arthritis. One of the hallmarks of rheumatoid arthritis is the loss of tolerance against citrullinated proteins. Citrullination is a post-translational modification of arginine residues, leading to a change in structure and function of the respective protein. This modification, which is catalyzed by peptidylarginine deiminases (PADs), plays a role in several physiological processes in the human body. Interestingly, P. gingivalis secretes a citrullinating enzyme, known as P. gingivalis PAD (PPAD), which targets bacterial and human proteins. Because the extent of P. gingivalis protein citrullination by PPAD was not yet known, the present study was aimed at identifying the extracellular proteome and citrullinome of P. gingivalis. To this end, extracellular proteins of two reference strains, two PPAD-deficient mutants, and three clinical isolates of P. gingivalis were analyzed by mass spectrometry. The results uncovered substantial heterogeneity in the extracellular proteome and citrullinome of P. gingivalis, especially in relation to the extracellular detection of typical cytoplasmic proteins. In contrast, the major virulence factors of P. gingivalis were identified in all investigated isolates, although their citrullination was shown to vary. This may be related to post-translational processing of the PPAD enzyme. Altogether, our findings focus attention on the possible roles of 6 to 25 potentially citrullinated proteins, especially the gingipain RgpA, in periodontitis and rheumatoid arthritis.

PMID- 27712080 TI - Diet, the intestinal microbiota, and immune health in aging. AB - Many countries are facing aging populations, with those over 65 years of age likely to represent the largest population over the next 10-20 years. Living longer often comes with poor health and, in particular, a decline in the immune function characterized by poor vaccine responses and increased risk of infection and certain cancers. Aging and diet represent major intrinsic and extrinsic factors that influence the makeup and activity of resident intestinal microbes, the microbiota, the efficient functioning of which is essential for sustaining overall health and the effectiveness of the immune system. The provision of elderly specific dietary recommendations appears to be lacking but is necessary since this population has an altered microbiota and immune response and may not respond in the same way as their healthy and younger counterparts. We have reviewed the evidence supporting the role of diet and, in particular, dietary carbohydrate, protein, and fat in influencing the microbiota and its generation of key metabolites that influence the efficient functioning of immune cells during aging, and how dietary intervention might be of benefit in improving the intestinal health and immune status in the elderly. PMID- 27712082 TI - Fit-for-purpose biomarker immunoassay qualification and validation: three case studies. AB - AIM: To improve on the efficiency of biomarker assay readiness, and for reliable biomarker data to support three drug programs, we implemented a fit-for-purpose approach, qualifying two biomarker assays and validating a third. Results/methodology: The qualification strategy and selection of experiments for two exploratory biomarkers (CXCL1, CCL19) was determined by the intended use of the biomarker data. The third biomarker, IL-6, was validated as the data would be used in monitoring patient safety during dose-escalation studies in a Phase I trial. All three assays passed a priori acceptance criteria. CONCLUSION: These assays highlight strategies and methodologies for a fit-for-purpose approach. Minimum qualification, full qualification and validation were chosen and supported programs at different stages of drug development. PMID- 27712081 TI - 2016 White Paper on recent issues in bioanalysis: focus on biomarker assay validation (BAV) (Part 1 - small molecules, peptides and small molecule biomarkers by LCMS). AB - The 2016 10th Workshop on Recent Issues in Bioanalysis (10th WRIB) took place in Orlando, Florida with participation of close to 700 professionals from pharmaceutical/biopharmaceutical companies, biotechnology companies, contract research organizations, and regulatory agencies worldwide. WRIB was once again a 5-day, weeklong event - A Full Immersion Week of Bioanalysis including Biomarkers and Immunogenicity. As usual, it was specifically designed to facilitate sharing, reviewing, discussing and agreeing on approaches to address the most current issues of interest including both small and large molecule analysis involving LCMS, hybrid LBA/LCMS, and LBA approaches, with the focus on biomarkers and immunogenicity. This 2016 White Paper encompasses recommendations emerging from the extensive discussions held during the workshop, and is aimed to provide the bioanalytical community with key information and practical solutions on topics and issues addressed, in an effort to enable advances in scientific excellence, improved quality and better regulatory compliance. This white paper is published in 3 parts due to length. This part (Part 1) discusses the recommendations for small molecules, peptides and small molecule biomarkers by LCMS. Part 2 (Hybrid LBA/LCMS and regulatory inputs from major global health authorities) and Part 3 (large molecule bioanalysis using LBA, biomarkers and immunogenicity) will be published in the Bioanalysis journal, issue 23. PMID- 27712083 TI - Aortic valve leaflet wall shear stress characterization revisited: impact of coronary flow. AB - Computational characterizations of aortic valve hemodynamics have typically discarded the effects of coronary flow. The objective of this study was to complement our previous fluid-structure interaction aortic valve model with a physiologic coronary circulation model to quantify the impact of coronary flow on aortic sinus hemodynamics and leaflet wall shear stress (WSS). Coronary flow suppressed vortex development in the two coronary sinuses and altered WSS magnitude and directionality on the three leaflets, with the most substantial differences occurring in the belly and tip regions. PMID- 27712084 TI - Hope and social support in elderly patients with cancer and their partners: an actor-partner interdependence model. AB - AIM: Assess relationships between oldest-old (minimum 86 years) patients' perceived social support to their own and their spousal caregivers' hope through application of the actor-partner interdependence model (APIM). PATIENTS & METHODS: 58 dyads of patients and their spousal caregivers completed standardized self-report measures of depression, distress, hope and social support. RESULTS: Patients presented high distress levels. Among patients and spouses, perceived social support was positively correlated to their own level of hope (beta = 0.44, p < 0.0001; beta = 0.56, p < 0.0001, respectively) and negatively correlated to the other's level of hope (beta = -0.25, p < 0.024; beta = -0.44, p < 0.0001, respectively). CONCLUSION: The actor-partner interdependence model was found to be adequate for describing relationships between social support and hope among dyads of oldest-old patients and their spousal caregivers. Patients and caregiver seem to utilize social support to enhance hope. PMID- 27712085 TI - 'They've invited me into their world': a focus group with clinicians delivering a behaviour change intervention in a UK contraceptive service. AB - Although teenage conceptions rates in the United Kingdom (UK) have seen a downward trend recently, it remains imperative that contraceptive services for young people continue to improve. To ensure that evidence-based interventions are sustained in clinical practice, it is useful to assess the experiences of those delivering them. This study explores the experiences of sexual health clinicians who were trained to deliver a one-to-one behaviour change intervention aiming to improve contraceptive use in young women. The intervention was set in a UK NHS contraceptive and sexual health service and involved clinicians' facilitating (within one-to-one consultations) the formation of implementation intentions (or 'if-then' plans) that specified when, where and how young women would use contraception. A focus group was conducted with seven clinicians who had delivered the intervention. A thematic analysis of the focus group revealed three overall themes: (1) How the intervention worked in practice; (2) barriers and benefits to delivering the intervention; and (3) positive changes to individual consultation style and wider 'best practice' within the clinic. Our findings show that, with support, clinical staff would be in favour of incorporating if-then planning as a strategy to help promote contraceptive adherence in young women. PMID- 27712086 TI - Evaluation and selection of a non-PCR based technology for improved gene expression profiling from clinical formalin-fixed, paraffin-embedded samples. AB - AIM: Formalin-fixed, paraffin-embedded (FFPE) clinical tissue samples have the potential to provide valuable gene-expression data for the development of cancer biomarkers. However, FFPE RNA is extensively fragmented, presenting a significant challenge for reliably detecting gene expression using traditional qPCR methods. RESULTS: We evaluated three novel methodologies along with the traditional qPCR method for their ability to detect Notch pathway gene expression in colorectal cancer FFPE tissue RNAs. We found that quantitative nuclease protection assay detected gene expression in high-quality RNAs as sensitively as qPCR, and consistently detected mRNAs in highly fragmented FFPE tissue RNAs. CONCLUSION: Quantitative nuclease protection assay represents an improved methodology for detecting gene expression in FFPE tissue and has the potential to advance the development of cancer biomarkers. PMID- 27712087 TI - Development and validation of an IA-LC/MS method to quantitate active and total B type natriuretic peptide in human plasma. AB - AIM: Patients with elevated levels of B-type natriuretic peptide (BNP) and/or NT proBNP as measured by clinical tests have an elevated risk of heart failure (HF). Despite utility in large clinical studies, both assays are plagued by large biological variability and specificity issues. To address these concerns and further investigate BNP in the HF setting, we developed an LC/MS assay to characterize the ratio of active to total BNP. RESULTS: We have developed and validated a novel immunoaffinity LC/MS assay to measure BNP-derived fragments, as well as 'total BNP' in human plasma. The ratio of active BNP1-32 to total BNP in 11 HF subjects was found to be <8%, and the sum of detectable BNP fragments contributed approximately 20% of total BNP. CONCLUSION: We developed an assay with the specificity to measure the active form of BNP, which may aid in the accurate diagnosis and better management of HF. PMID- 27712088 TI - Are school meals a viable and sustainable tool to improve the healthiness and sustainability of children's diet and food consumption? A cross-national comparative perspective. AB - There is little agreement among governments, institutions, scientists and food activists as to how to best tackle the challenging issues of health and sustainability in the food sector. This essay discusses the potential of school meals as a platform to promote healthy and sustainable food behavior. School meal programs are of particular interest for improving public diet because they reach children at a population scale across socio-economic classes and for over a decade of their lives, and because food habits of children are more malleable than those of adults. Current research on the history and health implications of school meal programs is reviewed in a cross-national comparative framework, and arguments explored that speak for the need of a new developmental phase of school meals as an integrative learning platform for healthy and sustainable food behavior. Nutritional, social, practical, educational, economical, political, and cultural perspectives and challenges linked to the implementation of healthy and sustainable school meals are discussed. Finally, the need for long-term interventions and evaluations is highlighted and new research directions are proposed. PMID- 27712089 TI - Tolerance and hyperaccumulation of a mixture of heavy metals (Cu, Pb, Hg, and Zn) by four aquatic macrophytes. AB - In the present investigation, four macrophytes, namely Typha latifolia (L.), Lemna minor (L.), Eichhornia crassipes (Mart.) Solms-Laubach, and Myriophyllum aquaticum (Vell.) Verdc, were evaluated for their heavy metal (Cu, Pb, Hg, and Zn) hyperaccumulation potential under laboratory conditions. Tolerance analyses were performed for 7 days of exposure at five different treatments of the metals mixture (Cu+2, Hg+2, Pb+2, and Zn+2). The production of chlorophyll and carotenoids was determined at the end of each treatment. L. minor revealed to be sensitive, because it did not survive in all the tested concentrations after 72 hours of exposure. E. crassipes and M. aquaticum displayed the highest tolerance to the metals mixture. For the most tolerant species of aquatic macrophytes, The removal kinetics of E. crassipes and M. aquaticum was carried out, using the following mixture of metals: Cu (0.5 mg/L) and Hg, Pb, and Zn 0.25 mg/L. The obtained results revealed that E. crassipes can remove 99.80% of Cu, 97.88% of Pb, 99.53% of Hg, and 94.37% of Zn. M. aquaticum withdraws 95.2% of Cu, 94.28% of Pb, 99.19% of Hg, and 91.91% of Zn. The obtained results suggest that these two species of macrophytes could be used for the phytoremediation of this mixture of heavy metals from the polluted water bodies. PMID- 27712090 TI - Use of horizontal subsurface flow constructed wetlands to treat reverse osmosis concentrate of rolling wastewater. AB - According to the characteristics of the reverse osmosis concentrate (ROC) generated from iron and steel company, we used three sets of parallel horizontal subsurface flow (HSF) constructed wetlands (CWs) with different plants and substrate layouts to treat the high-salinity wastewater. The plant growth and removal efficiencies under saline condition were evaluated. The evaluation was based entirely on routinely collected water quality data and the physical and chemical characteristics of the plants (Phragmites australis, Typha latifolia, Iris wilsonii, and Scirpus planiculmis). The principal parameters of concern in the effluent were chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP). The results showed that the CWs were able to remove COD, TN, and TP from ROC. S. planiculmis was not suitable for the treatment of high-saline wastewater. The sequence of metals accumulated in CW plants was K>Ca>Na>Mg>Zn>Cu. More than 70% of metals were accumulated in the aboveground of P. australis. The CW filled with gravel and manganese ore and planted with P. australis and T. latifolia had the best performance of pollutant removal, with average removal of 49.96%, 39.45%, and 72.01% for COD, TN, and TP, respectively. The effluent water quality met the regulation in China. These results suggested that HSF CW planted with P. australis and T. latifolia can be applied for ROC pollutants removal. PMID- 27712091 TI - Sustained high-pressure in the spinal subarachnoid space while arterial expansion is low may be linked to syrinx development. AB - Syringomyelia (a spinal cord cyst) usually develops as a result of conditions that cause cerebrospinal fluid (CSF) obstruction. The mechanism of syrinx formation and enlargement remains unclear, though previous studies suggest that the fluid enters via the perivascular spaces (PVS) of the penetrating arteries of the spinal cord, and that alterations in the CSF pulse timing and pressure could contribute to enhanced PVS inflow. This study uses an idealised computational model of the PVS to investigate the factors that influence peri-arterial fluid flow. First, we used three sample patient-specific models to explore whether changes in subarachnoid space (SAS) pressures in individuals with and without syringomyelia could influence PVS inflow. Second we conducted a parametric study to determine how features of the CSF pulse altered perivascular fluid, including alterations to timing and magnitude of the peak SAS pressure, the timing of reversal from high to low pressure (diastolic phase), and the area under the pressure-time curve. The model for the patient with syringomyelia had higher net CSF inflow to the PVS than the two subjects without syringomyelia. In the parametric study, only increasing the area under the high pressure region of the SAS pulse substantially increased PVS inflow, when coupled with a temporal shift in arterial and SAS pulses. This suggests that a period of sustained high SAS pressure while arterial diameter is low may increase net CSF pumping into the PVS.

PMID- 27712093 TI - Addressing taxane resistance in metastatic castration-resistant prostate cancer: a focus on chaperone proteins. AB - Despite the significant survival benefit of taxane therapy in metastatic castration-resistant prostate cancer (mCRPC), all patients inevitably develop treatment resistance. An understanding of resistance mechanisms has led to new therapies for prostate cancer (cabazitaxel, abiraterone and enzalutamide), all of which have improved survival following first-line docetaxel. Another treatment, currently in development, targets the prosurvival molecule clusterin. Custirsen, an antisense molecule that inhibits clusterin production, has shown promise in combination with docetaxel in mCRPC patients at risk for poor outcomes. Although optimal sequence and combination of available therapies is unclear, the heterogeneity of mCRPC suggests a continuing need for personalized treatment regimens and improved abilities to predict which patients will respond to the available treatment options. PMID- 27712094 TI - Relationship between daily training load and psychometric status of professional soccer players. AB - We studied the relationship between daily training load (TL) experienced by professional soccer players and the Hooper questionnaire reflecting their perceived quality of sleep, fatigue, stress and delayed onset muscle soreness. During a 16-week training period, the rating of perceived exertion and duration were collected after each training session, and daily TL was calculated from 14 professional soccer players. The Hooper questionnaire was completed every day before the first training session and the Hooper's score (HS) was then calculated. The daily TL and HS were 379.9 +/- 198.3 AU and 16.2 +/- 5.1, respectively. Pearson correlation showed significant relationships (p < 0.01) between TL and perceived fatigue, muscle soreness, sleep and stress. Our findings revealed that the perceived sleep, stress, fatigue and muscle soreness are moderately related to the daily TL in professional soccer players. The Hooper questionnaire is both a simple and useful tool for monitoring perceived wellness and psychometric players' status of professional soccer players. PMID- 27712095 TI - Predicting dental attendance from dental hygienists' autonomy support and patients' autonomous motivation: A randomised clinical trial. AB - OBJECTIVE: To test the hypothesis that a Self-Determination Theory (SDT) intervention designed to promote oral health care competence in an autonomy supportive way would predict change in caries competence relative to standard care. Further, to test the SDT process path-model hypotheses with: (1) the intervention and individual differences in relative autonomous locus of causality (RALOC) predicting increases in caries competence, which in turn would positively predict dental attendance; (2) RALOC negatively predicting dental anxiety, which would negatively predict dental attendance; (3) RALOC and caries disease referred to the dentist after an autonomy-supportive clinical exam directly positively predicting dental attendance; and (4) the intervention moderating the link between RALOC and dental attendance. DESIGN: A randomised two-group experiment was conducted at a dental clinic with 138 patients (Mage = 23.31 yr., SD = 3.5), with pre- and post-measures in a period of 5.5 months. RESULTS: The experimental model was supported. The SDT path model fit the data well and supported the hypotheses explaining 63% of the variance in dental attendance. CONCLUSIONS: Patients personality (RALOC) and hygienists promoting oral health care competence in an autonomy-supportive way, performance of autonomy-supportive clinical exams and reductions of anxiety for dental treatment have important practical implications for patients' dental attendance. PMID- 27712096 TI - Guardians' Perceptions of Dogs' Welfare and Behaviors Related to Visiting the Veterinary Clinic. AB - A large survey of Italian dog guardians (n = 906) was conducted to assess dog behavior and welfare at the veterinary clinic and to investigate how guardians and veterinarians affect them. This study confirmed that the veterinary clinic is a source of stress for most dogs, who showed impaired welfare in all phases: in the waiting room, entering the examination room, on the examination table, and when approached by the vet. This study also characterizes some factors related to the guardians' and veterinarians' behavior that affect the dogs' behavior and welfare during the veterinary examination. If dogs had not been examined by a vet since puppyhood, if they did not accept treatments by their guardians, and if they were scolded when refusing a treatment, the risk for having problems with dog welfare and behavior at the veterinary clinic increased. The attention paid by the vet to the dog was found to be positively related with a good response of the dog to the vet. Prevention seems to be the key for the protection of dog welfare related to veterinary care.

AB - Investigation of the ethanol extract of the corms of Liatris spicata (L.) willd led to the isolation of two sterols: stigmasterol and its 3-O-glucoside, a triterpene: obtusifoliyl acetate, two benzofurans: euparin and 6-hydroxy-3 methoxytremetone, three phenolic acids: protocatechuic, vanillic and ferulic acid and a sesquiterpene lactone igalan. The structures of the isolated compounds were established on the basis of physicochemical properties and spectral analysis (IR, EI/MS, 1H NMR and 13C NMR). The ethanol extract and its isolated compounds evidenced cytotoxic activities against human liver cancer cell line (HepG2), where igalan showed the highest potency (3.83 +/- 0.043) MUg/mL, its effect was comparable to that of the standard drug doxorubicin(r) (3.73 +/- 0.036) MUg/mL.

AB - Biomechanical forces are emerging as critical regulators of embryogenesis, particularly in the developing cardiovascular system. From the onset of blood flow, the embryonic vasculature is continuously exposed to a variety of hemodynamic forces. These biomechanical stimuli are key determinants of vascular cell specification and remodeling and the establishment of vascular homeostasis. In recent years, major advances have been made in our understanding of mechano activated signaling networks that control both spatiotemporal and structural aspects of vascular development. It has become apparent that a major site for mechanotransduction is situated at the interface of blood and the vessel wall and that this process is controlled by the vascular endothelium. In this review, we discuss the hemodynamic control of endothelial cell fates, focusing on arterial venous specification, lymphatic development, and the endothelial-to-hematopoietic transition, and present some recent insights into the mechano-activated pathways driving these cell fate decisions in the developing embryo. PMID- 27712103 TI - Monitoring of pistachio (Pistacia Vera) ripening by high field nuclear magnetic resonance spectroscopy. AB - The metabolic profiling of pistachio (Pistacia vera) aqueous extracts from two different cultivars, namely 'Bianca' and 'Gloria', was monitored over the months from May to September employing high field NMR spectroscopy. A large number of water-soluble metabolites were assigned by means of 1D and 2D NMR experiments. The change in the metabolic profiles monitored over time allowed the pistachio development to be investigated. Specific temporal trends of amino acids, sugars, organic acids and other metabolites were observed and analysed by multivariate Partial Least Squares (PLS) analysis. Statistical analysis showed that while in the period from May to September there were few differences between the two cultivars, the ripening rate was different. PMID- 27712102 TI - TCR Signal Strength and T Cell Development. AB - Thymocyte selection involves the positive and negative selection of the repertoire of T cell receptors (TCRs) such that the organism does not suffer autoimmunity, yet has the benefit of the ability to recognize any invading pathogen. The signal transduced through the TCR is translated into a number of different signaling cascades that result in transcription factor activity in the nucleus and changes to the cytoskeleton and motility. Negative selection involves inducing apoptosis in thymocytes that express strongly self-reactive TCRs, whereas positive selection must induce survival and differentiation programs in cells that are more weakly self-reactive. The TCR recognition event is analog by nature, but the outcome of signaling is not. A large number of molecules regulate the strength of the TCR-derived signal at various points in the cascades. This review discusses the various factors that can regulate the strength of the TCR signal during thymocyte development. PMID- 27712104 TI - Assessment of Welfare Issues During Traditional Slaughter of Goats in Pretoria, South Africa. AB - Goats are traditionally slaughtered to celebrate marriages and births, venerate ancestors, address personal problems, or perform a ritual during funerals. The objective of this study was to assess nonhuman animal welfare issues associated with the traditional slaughter of goats in and around Pretoria, South Africa. Participatory research methods were used to interview 105 respondents. Four of those interviewed were visited to observe the slaughter process. The most common method of transport was a vehicle (47%), followed by transport on foot (30%). The distance traveled (68%) was usually less than 10 km, and in all cases, it was less than 50 km. The most common (57%) method of restraining goats during transport was tying all 4 legs together. During slaughter, assistants held the head and legs of the goat (55%). Prior to slaughter, the majority of goats were tied under a tree (66%). In total, 97% of the goats were slaughtered within 24 hr, and no stunning was performed. In this study, animal welfare problems were widespread. Research should be undertaken to find practical ways to address animal welfare issues during traditional slaughter. PMID- 27712106 TI - A Pilot Study of Eight-Session Mindfulness-Based Cognitive Therapy Adapted for Women's Sexual Interest/Arousal Disorder. AB - While few treatment options exist for low sexual desire and arousal, the most common sexual dysfunction in women, a growing body of research supports the efficacy of mindfulness-based approaches. The mechanisms underlying improvements, and whether they are due to mindfulness practice or other treatment components, are unclear. As a result, we designed and pilot-tested an eight-session group mindfulness-based cognitive therapy for sexuality (MBCT-S) program that includes more extensive practice of mindfulness skills and closely aligns with the evidence-based MBCT program for depression and anxiety. A total of 26 women (mean age 43.9, range 25 to 63) with a diagnosis of sexual interest/arousal disorder participated in eight weekly group sessions, before and after which they completed validated questionnaires. The majority of women attended all sessions and completed the recommended at-home mindfulness exercises. Compared to baseline, women reported significant improvements in sexual desire, overall sexual function, and sex-related distress, regardless of treatment expectations, relationship duration, or low desire duration. Depressed mood and mindfulness also significantly improved and mediated increases in sexual function. These pilot data suggest that eight-session MBCT-S is feasible and significantly improves sexual function, and provide the basis for a larger randomized controlled trial (RCT) with a longer follow-up period. PMID- 27712099 TI - The Pathophysiologic Role of Disrupted Circadian and Neuroendocrine Rhythms in Breast Carcinogenesis. AB - Most physiological processes in the brain and body exhibit daily (circadian) rhythms coordinated by an endogenous master clock located in the suprachiasmatic nucleus of the hypothalamus that are essential for normal health and functioning. Exposure to sunlight during the day and darkness at night optimally entrains biological rhythms to promote homeostasis and human health. Unfortunately, a major consequence of the modern lifestyle is increased exposure to sun-free environments during the day and artificial lighting at night. Additionally, behavioral disruptions to circadian rhythms (ie, repeated transmeridian flights, night or rotating shift work, or sleep disturbances) have a profound influence on health and have been linked to a number of pathological conditions, including endocrine-dependent cancers. Specifically, night shift work has been identified as a significant risk factor for breast cancer in industrialized countries. Several mechanisms have been proposed by which shift work-induced circadian disruptions promote cancer. In this review, we examine the importance of the brain-body link through which circadian disruptions contribute to endocrine dependent diseases, including breast carcinogenesis, by negatively impacting neuroendocrine and neuroimmune cells, and we consider preventive measures directed at maximizing circadian health. PMID- 27712105 TI - Normative data for evaluating mild traumatic brain injury with a handheld neurocognitive assessment tool. AB - The BrainScope Ahead 300 is designed for use by health care professionals to aid in the assessment of patients suspected of a mild traumatic brain injury. The purpose of the current study was to establish normative data for the cognitive test component of the Ahead 300 system and to evaluate the role of demographic factors on test performance. Healthy, community-dwelling adults between the ages of 18 and 80 recruited from five geographically distributed sites were administered Android versions of the ANAM Matching to Sample and Procedural Reaction Time tests that comprise the cognitive test component of the Ahead 300 system by trained personnel. Scores were correlated with age, education, and race. Age accounted for the majority of the variance in test scores with additional significant, but minor, contributions of education and race. Gender did not account for a significant proportion of the variance for either test. Based on these results, the normative data for 551 individuals are presented stratified by age. These are the first available normative data for these tests when administered using the Ahead 300 system and will assist health care professionals in determining the degree to which scores on the cognitive tests reflect impaired performance. PMID- 27712107 TI - Light Therapy With Scheduled Rise Times in Young Adults With Delayed Sleep Phase Disorder: Therapeutic Outcomes and Possible Predictors. AB - Clinical trials with light therapy (LT) for delayed sleep phase disorder (DSPD) are sparse and little is known about factors that are favorable for improvements. In this study, LT with scheduled rise times was conducted at home for 14 days by 44 participants with DSPD aged 16-26 years. Primary outcomes were sleep onset and sleep offset. Potential predictors were demographic characteristics, chronotype, dim light melatonin onset, the number of days the LT lamp was used, the daily duration of LT, daytime sleepiness, anxiety, depression, worry, and rumination. Significant advances were observed in sleep onset and sleep offset from baseline to the end of treatment. The number of days of LT predicted earlier sleep onset and sleep offset. PMID- 27712108 TI - Sexual Behavior Latent Classes Among Men Who Have Sex With Men: Associations With Sexually Transmitted Infections. AB - Men who have sex with men (MSM) are at disproportionate risk of acquisition of sexually transmitted infections (STIs). We used latent class analysis (LCA) to examine patterns of sexual behavior among MSM and how those patterns are related to STIs. We examined patterns of sexual behavior using behavioral and clinical data from a cross-sectional study of 235 MSM who presented to an urban sexual health clinic for STI testing. Analyzed data were collected using a combination of interviewer- and self-administered surveys and electronic health records. We used LCA to identify underlying subgroups of men based on their sexual behavior, described the demographics of the latent classes, and examined the association between the latent classes and STI status. We identified three latent classes of sexual behavior: Unprotected Anal Intercourse (UAI) Only (67%), Partner Seekers (14%), and Multiple Behaviors (19%). Men in the Multiple Behaviors class had a 67% probability of being STI positive, followed by men in the UAI Only class (27%) and men in the Partner Seekers class (22%). Examining the intersection of a variety of sexual practices indicates particular subgroups of MSM have the highest probability of being STI positive. PMID- 27712109 TI - Assessing Stress-Induced Sleep Reactivity in College Students: The European Portuguese Version of the Ford Insomnia Response to Stress Test (FIRST). AB - OBJECTIVE AND BACKGROUND: Over the past few years, the comprehensive models of insomnia have exhibited impressive developments. However, there is scarce knowledge on predisposing or vulnerability factors for insomnia. One of the most promising constructs to aid in filling this gap is stress-induced sleep reactivity assessed through self-report. Our aim was to study the psychometric properties of the European Portuguese version of the Ford Insomnia Response to Stress Test (FIRST). PARTICIPANTS: We recruited a large sample of students attending medical school (N = 699). METHODS: Several analyses were carried out such as internal consistency, construct validity, and discriminant groups' analysis. RESULTS: It was observed that FIRST-PT shows good internal consistency (Cronbach's alpha = .81) and validity indicators. Interestingly, and contrary to what was observed in the previously published studies on psychometric properties of the FIRST, it was observed that a two-factor solution (Factor I = rumination, Factor II = worry) was the most adequate one to explain the correlation matrix, accounting for approximately 44% of the total variance. CONCLUSIONS: The FIRST-PT proved to be a useful and reliable tool to measure stress-induced sleep reactivity. However, these results should be replicated in other groups, particularly clinical samples, in order to verify the stability of its factorial dimension. PMID- 27712110 TI - CADASIL and multiple sclerosis: A case report of prolonged misdiagnosis. AB - CADASIL is Cerebral Autosomal-Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy [corrected]. (CADASIL) is sometimes misdiagnosed as multiple sclerosis (MS). MS and CADASIL are not known to co-occur and brain magnetic resonance imagining (MRI) findings can help with differential diagnosis. Despite the availability of this information, a case report is presented of a 61-year-old woman who was misdiagnosed with MS at age 50, tested positive for CADASIL at age 56, described incorrectly as having both conditions simultaneously, and continued on MS disease-modifying medications, resulting in financial and physical hardship. Neuropsychological consultation helped initiate removal of the MS diagnosis and treatment. Better understanding is needed among clinicians that MS and CADASIL are not known to co-exist, that no association has been found between MS and the NOTCH3 mutations that cause CADASIL, and that neuroimaging and clinical features can help distinguish between the two conditions in addition to genetic testing. This case study highlights how neuropsychological consultation involves more than testing, can help improve diagnostic decision making, and can improve outcomes by reducing costs to the patient and the healthcare system. PMID- 27712111 TI - Mastery, Isolation, or Acceptance: Gay and Bisexual Men's Construction of Aging in the Context of Sexual Embodiment After Prostate Cancer. AB - Age is the predominant risk factor for developing prostate cancer, leading to its description as an "older man's disease." Changed sexual embodiment is a concern for men who develop prostate cancer, often compounding experiences of age-related sexual decline. Although research has examined heterosexual men's experiences of aging in the context of sexual embodiment after prostate cancer, gay and bisexual men have received little attention. This qualitative study used a material discursive analysis, drawing on positioning theory and intersectionality, to explore constructions of aging following prostate cancer in 46 gay or bisexual men. Thematic decomposition of one-to-one interviews identified three subject positions: "mastering youth," involving maintaining an active sex life through biomedical interventions, accessing commercial sex venues, or having sex with younger men; "the lonely old recluse," involving self-positioning as prematurely aged and withdrawal from a gay sexual scene; and "accepting embodied aging," involving the incorporation of changed sexual function into intimate relationships and finding pleasure through nonsexual activities. These subject positions are conceptualized as the product of intersecting masculine and gay identities, interpreted in relation to broader cultural discourses of "new aging" and "sexual health," in which sexual activity is conceptualized as a lifelong goal. PMID- 27712112 TI - Attentional bias toward alcohol-related stimuli in heavy drinkers: evidence from dynamic eye movement recording. AB - BACKGROUND: It has been proposed that attentional biases toward alcohol stimuli are contributing factors maintaining problematic drinking behavior. OBJECTIVE: The main goal of the present set of studies was to provide an examination of dynamic attentional mechanisms associated with alcohol consumption derived from eye movement monitoring. METHOD: Undergraduate students were recruited for two studies. In Experiment 1, 80 students were exposed to complex scenes (containing alcohol-related cues or not) viewed at a self-determined presentation rate. In Experiment 2, 80 students were exposed to the stimuli for a fixed presentation time and asked to memorize the photographs. In both studies, participants completed the Khavari Alcohol Test (KAT) to measure their drinking behaviors. RESULTS: Experiment 1 revealed that alcohol consumption was unrelated to eye movement measures on alcohol-related objects within pictures. However, results of Experiment 2 indicated that saccades into and out of the alcohol-related zones were more frequent as alcohol consumption increased. The time spent and the speed of the first fixation in the alcohol-related zone did not explain the variance in alcohol consumption. CONCLUSION: Attentional biases associated with alcohol consumption might be better understood in terms of dynamic attention mechanisms. More precisely, heavy drinker's attention seems to be constantly drawn back to alcohol-related objects once they are first fixated and when attention is enforced through other cognitive demands. From a clinical viewpoint, dynamic attentional biases might contribute to the development or maintenance of alcohol related problems and this observation might help guide attention-based interventions. PMID- 27712114 TI - Hidden Markov Item Response Theory Models for Responses and Response Times. AB - Current approaches to model responses and response times to psychometric tests solely focus on between-subject differences in speed and ability. Within subjects, speed and ability are assumed to be constants. Violations of this assumption are generally absorbed in the residual of the model. As a result, within-subject departures from the between-subject speed and ability level remain undetected. These departures may be of interest to the researcher as they reflect differences in the response processes adopted on the items of a test. In this article, we propose a dynamic approach for responses and response times based on hidden Markov modeling to account for within-subject differences in responses and response times. A simulation study is conducted to demonstrate acceptable parameter recovery and acceptable performance of various fit indices in distinguishing between different models. In addition, both a confirmatory and an exploratory application are presented to demonstrate the practical value of the modeling approach. PMID- 27712113 TI - Palonosetron and hydroxyzine pre-treatment reduces the objective signs of experimentally-induced acute opioid withdrawal in humans: a double-blinded, randomized, placebo-controlled crossover study. AB - BACKGROUND: Treatments for reducing opioid withdrawal are limited and prone to problematic side effects. Laboratory studies, clinical observations, and limited human trial data suggest 5-HT3-receptor antagonists and antihistamines may be effective. OBJECTIVES: This double-blind, crossover, placebo-controlled study employing an acute physical dependence model evaluated whether (i) treatment with a 5-HT3-receptor antagonist (palonosetron) would reduce opioid withdrawal symptoms, and (ii) co-administration of an antihistamine (hydroxyzine) would enhance any treatment effect. METHODS: At timepoint T = 0, healthy (non-opioid dependent, non-substance abuser) male volunteers (N = 10) were pre-treated with either a) placebo, b) palonosetron IV (0.75 mg), or c) palonosetron IV (0.75 mg) and hydroxyzine PO (100 mg) in a crossover study design. This was followed at T = 30 by intravenous morphine (10 mg/70kg). At T = 165, 10 mg/70kg naloxone IV was given to precipitate opioid withdrawal. The objective opioid withdrawal score (OOWS) and subjective opioid withdrawal score (SOWS) were determined 5 and 15 minutes after naloxone administration (T = 170, 180, respectively). Baseline measurements were recorded at T = -30 and T = -15. RESULTS: Comparison of average baseline OOWS scores with OOWS scores obtained 15 minutes after naloxone was significant (p = 0.0001). Scores from 15 minutes post-naloxone infusion showed significant differences in OOWS scores between treatment groups: placebo, 3.7 +/- 2.4; palonosetron, 1.5 +/- 0.97; and palonosetron with hydroxyzine, 0.2 +/- 0.1333. CONCLUSIONS: Pretreatment with palonosetron significantly reduced many signs of experimentally-induced opioid withdrawal. Co-administration with hydroxyzine further reduced opioid withdrawal severity. These results suggest that 5-HT3 receptor antagonists, alone or in combination with an antihistamine, may be useful in the treatment of opioid withdrawal. PMID- 27712115 TI - An exploration of pain-related vocabulary: implications for AAC use with children. AB - Children with significant communication difficulties who experience pain need appropriate means to communicate their pain in order to receive appropriate treatment. Augmentative and alternative communication (AAC) strategies could be used to enable children to self-report pain. The aim of this research study was to identify the common vocabulary children with typical development use to describe physical pain experiences and develop and socially validate an appropriate pain-related vocabulary list for children who use or could benefit from using AAC. A sequential, exploratory, mixed-method design was employed. This paper focuses on the quantitative phase. A set of scenarios was developed to gather pain-related vocabulary appropriate for children aged 6;0-7;11 (years;months) and children aged 8;0-9;11, from 74 children, 61 parents, and 56 teachers. Some 629 pain-related words or phrases were suggested and then classified into seven categories. A composite list of the 84 most frequently occurring pain-related vocabulary items was compiled and socially validated by three adults who used AAC. They emphasized the need to individualize vocabulary and provided suggestions for vocabulary organization for display on any type of AAC system. Despite similarities in the categories of words offered by the various respondent groups, the differences underscore the importance of more than one perspective (particularly that of children and adults) in generating a comprehensive vocabulary list. PMID- 27712116 TI - Estimation of the Coefficient of Variation with Minimum Risk: A Sequential Method for Minimizing Sampling Error and Study Cost. AB - The coefficient of variation is an effect size measure with many potential uses in psychology and related disciplines. We propose a general theory for a sequential estimation of the population coefficient of variation that considers both the sampling error and the study cost, importantly without specific distributional assumptions. Fixed sample size planning methods, commonly used in psychology and related fields, cannot simultaneously minimize both the sampling error and the study cost. The sequential procedure we develop is the first sequential sampling procedure developed for estimating the coefficient of variation. We first present a method of planning a pilot sample size after the research goals are specified by the researcher. Then, after collecting a sample size as large as the estimated pilot sample size, a check is performed to assess whether the conditions necessary to stop the data collection have been satisfied. If not an additional observation is collected and the check is performed again. This process continues, sequentially, until a stopping rule involving a risk function is satisfied. Our method ensures that the sampling error and the study costs are considered simultaneously so that the cost is not higher than necessary for the tolerable sampling error. We also demonstrate a variety of properties of the distribution of the final sample size for five different distributions under a variety of conditions with a Monte Carlo simulation study. In addition, we provide freely available functions via the MBESS package in R to implement the methods discussed. PMID- 27712118 TI - Zika virus epidemic: an update. AB - INTRODUCTION: Zika Virus (ZIKV), previously the cause of only rare and sporadic human infections, is now considered a Public Health Emergency of International Concern. Over the past two years, ZIKV has become a pandemic encompassing much of the Americas. ZIKV is now proven to cause microcephaly and ophthalmic anomalies in the newborn. Hydrops fetalis, developmental delay, and other anomalies are increasingly being attributed to ZIKV infection in fetuses and neonates. Sequelae of congenital infection and rapid spread of ZIKV throughout the Americas has catapulted Zika virus concerns to the forefront of the medical community. Areas covered: This review seeks to consolidate ZIKV epidemiology, diagnostic testing methods, CDC screening recommendations, and preventive strategies including potential vaccines. Expert commentary: Many unknowns still exist regarding ZIKV infections and its long-term effects in neonates. In addition, further studies need to evaluate if genomic differences that have occurred from the African to the Asian lineage of the virus have led to increased virulence of the virus. The authors believe that all pregnant women with fetuses showing microcephaly and/or intracranial calcifications should be tested for ZIKV infection if they cannot recall their sexual partner travel history. This change from the current CDCs recommendations could increase substantially the number of pregnant women and neonates, screened for ZIKV. PMID- 27712120 TI - Craving, prayer, and the brain. PMID- 27712117 TI - Clinical relevance of midline fluid percussion brain injury: Acute deficits, chronic morbidities and the utility of biomarkers. AB - BACKGROUND: After 30 years of characterisation and implementation, fluid percussion injury (FPI) is firmly recognised as one of the best-characterised reproducible and clinically relevant models of TBI, encompassing concussion through diffuse axonal injury (DAI). Depending on the specific injury parameters (e.g. injury site, mechanical force), FPI can model diffuse TBI with or without a focal component and may be designated as mild-to-severe according to the chosen mechanical forces and resulting acute neurological responses. Among FPI models, midline FPI may best represent clinical diffuse TBI, because of the acute behavioural deficits, the transition to late-onset behavioural morbidities and the absence of gross histopathology. REVIEW: The goal here was to review acute and chronic physiological and behavioural deficits and morbidities associated with diffuse TBI induced by midline FPI. In the absence of neurodegenerative sequelae associated with focal injury, there is a need for biomarkers in the diagnostic, prognostic, predictive and therapeutic approaches to evaluate outcomes from TBI. CONCLUSIONS: The current literature suggests that midline FPI offers a clinically-relevant, validated model of diffuse TBI to investigators wishing to evaluate novel therapeutic strategies in the treatment of TBI and the utility of biomarkers in the delivery of healthcare to patients with brain injury. PMID- 27712119 TI - Identification of problems in the functioning of individuals with schizophrenia from the expert perspective: an Internet-based survey. AB - PURPOSE: The purpose of the study was to identify aspects of functioning and related environmental factors that are relevant to schizophrenia from the perspective of health professionals experienced in treating individuals with this disorder using the International Classification of Functioning, Disability and Health (ICF). METHOD: An international pool of experts from diverse health care disciplines was surveyed to identify problems in functioning experienced by individuals with schizophrenia and the environmental factors that impact their functioning. On the basis of established rules, all answers were translated to the ICF by two independent researchers. RESULTS: One-hundred and eighty-nine experts from all six World Health Organization regions identified 4776 meaningful concepts, of which 92% were linked to 347 different ICF categories. Of the 347 categories, 194 were second-level categories, 151 were third-level categories and 2 were fourth-level categories. Ninety-five second-level ICF categories, 43 third level categories and 1 fourth-level category reached percentage frequency of at least 5%. The majority of the categories were attributed to body functions, activities and participation, and environmental factors. CONCLUSIONS: Health professionals identified a wide range of problems in functioning that reflect the complexity and breadth of schizophrenia, specifically activity limitations and participation restrictions that are particularly relevant for individuals with schizophrenia. Knowing these functioning problems can guide the design of patient oriented rehabilitation programmes. Implications for rehabilitation Schizophrenia may result in impaired functioning in multiple daily life activities. The International Classification of Functioning, Disability and Health (ICF) can help in identifying the needs and problems of these individuals. The reported list of ICF categories can facilitate a systematic application of the ICF in schizophrenia and can help to design and implement coordinated and patient oriented rehabilitation programmes with a biopsychosocial approach. According to health professionals surveyed, activity limitations and participation restrictions are broadly affected in this population and are highly influenced by neurocognitive and social cognitive deficits and environmental factors. PMID- 27712121 TI - The importance of building trust and tailoring interactions when meeting older adults' health literacy needs. AB - PURPOSE: Health literacy is the ability to access, understand and use health information. This study qualitatively explored the views and experiences of older adults with varying health literacy levels who had attended a falls clinic on their overall experience of the falls clinic, access to the service and provider patient interaction. METHODS: Individual semi-structured interviews were conducted with nine older adults using a falls clinic in England. Health literacy was assessed using the REALM and NVS-UK. Interviews were audio-recorded, transcribed verbatim and interrogated using interpretative phenomenological analysis (IPA). RESULTS: Two superordinate themes emerged from the analysis: The importance of trust and relationship building to achieve effective communication with older adults; and the importance of tailoring education and healthcare to older adults' individual health literacy needs and preferences. CONCLUSIONS: The findings corroborate previous research emphasising the importance of face-to-face communication in responding to older adults' individual health literacy needs. Building trust in the relationship and tailoring communication to older adults' individual attributes and preferred learning styles is essential. Healthcare practitioners and managers should consider how service organisation and communication methods can enhance positive and effective relationships with patients. Improved training could support healthcare providers in meeting patients' personal communication needs. Implications for Rehabilitation Rehabilitation professionals should be aware of their patients' individual health literacy needs and communication/learning preferences. It is important to build relationships and trust with older adults attending rehabilitation services. Further training for rehabilitation professionals could support them in meeting patients' personal communication needs. PMID- 27712122 TI - The relationship between circulating visfatin/nicotinamide phosphoribosyltransferase, obesity, inflammation and lipids profile in elderly population, determined by structural equation modeling. AB - BACKGROUND: The available literature suggests that circulating visfatin/Nicotinamide Phosphoribosyltransferase (NAMPT) level variability in humans is related to obesity, insulin resistance, inflammation, and lipid profile. The aim of the study was to assess the relationship between circulating visfatin/NAMPT, obesity, insulin resistance, inflammation, and lipid profile in a large population-based, elderly cohort, applying structural equation modeling. MATERIALS AND METHODS: The analysis included 2983 elderly participants of the PolSenior study with assessed total blood count, fasting concentrations of lipids, glucose, insulin, hs-CRP, interleukin-6, and visfatin/NAMPT (by ELISA), and calculated HOMA-IR. RESULTS: The circulating visfatin/NAMPT levels were higher in obese compared to normal weight subjects, in those with hs-CRP above 3 mg/L, with low serum HDL cholesterol, and in insulin resistant subjects. Based on results of the exploratory factor analysis, a baseline model of mutual relationship between four latent and measured variables was created and a final model was developed by maintaining only two significant categories. The important variables for 'latent inflammation' proved to be hs-CRP and IL-6 serum levels. In the case of 'nutritional status', important variables were BMI, waist circumference, and to a lesser extent insulin resistance. Additionally, the residual correlation between those two constructs was also statistically significant. CONCLUSION: The structural equation modeling provided support for the existence of a link between nutritional status, inflammation and circulating visfatin/NAMPT level. This indicates that circulating visfatin/NAMPT can be considered as a novel surrogate marker of systemic inflammation associated with fat depot, especially visceral, in the elderly population. PMID- 27712123 TI - Intervening to address communication difficulties in incarcerated youth: A Phase 1 clinical trial. AB - PURPOSE: Although a number of studies have described high rates of wide-ranging language difficulties in youth offender samples, minimal intervention research has been conducted with this population. The aim of this study was to implement a small-scale speech-language pathology (SLP) intervention study in a secure youth justice facility and to identify key practical challenges associated with conducting SLP interventions in youth custodial settings. METHOD: Six young males were recruited and underwent assessment via a range of standardised and self report communication measures. Measures of nonverbal IQ and of therapeutic engagement were also employed, and participants' own goals concerning communication competence were incorporated into treatment. Participants completed seven to 16 weeks' of 1:1 SLP intervention, once or twice per week. RESULT: Therapeutic engagement was generally strong. All participants made gains and responded favourably regarding the usefulness of the intervention. Many practical issues conspired to make this a challenging SLP intervention setting. CONCLUSION: Youth custodial sentences represent an important opportunity for high-risk youths with compromised communication skills to receive specialist SLP therapeutic services to reduce the impact of their communication difficulties post-release into the community. PMID- 27712125 TI - The impact of childhood language difficulties on healthcare costs from 4 to 13 years: Australian longitudinal study. AB - PURPOSE: This study investigated the relationship between children's language difficulties and health care costs using the 2004-2012 Longitudinal Study of Australian Children (LSAC). METHOD: Language difficulties were defined as scores <=1.25SD below the standardised mean on measures of directly assessed receptive vocabulary (4-9 years) and teacher-reported language and literacy (10-13 years). Participant data were individually linked to administrative data, which were sourced from Australia's universal subsidised healthcare scheme (Medicare). RESULT: It was found that healthcare costs over each 2-year age band were higher for children with language difficulties than without in the 4-5-year-age bracket (mean difference = AU$357, 95%CI $59, $659), in the 6-7-year-age bracket (mean difference = AU$602, 95%CI $136, $1068) and in the 10-11-year-age bracket (mean difference = AU$504, 95%CI $153, $854). Out-of-pocket costs, that is the portion of healthcare costs paid for by the family, were also higher for children with than without language difficulties in the 4-5-year-age bracket (mean difference = AU$123, 95%CI $46, $199), in the 6-7-year-age bracket (mean difference = AU$176, 95%CI $74,278) and in the 10-11-year-age bracket (mean difference = AU$79, 95%CI $6, $152). Medical services accounted for 97% of total healthcare cost differences. CONCLUSION: Overall the findings from this study suggest that language difficulties are associated with increased healthcare costs at key developmental milestones, notably early childhood and as a child approaches the teenage years. PMID- 27712126 TI - Perceptions of e-cigarettes: a comparison of adult smokers and non-smokers in a Mechanical Turk sample. AB - BACKGROUND: Given plans to extend its regulatory authority to e-cigarettes, the Food and Drug Administration (FDA) urgently needs to understand how e-cigarettes are perceived by the public. OBJECTIVES: To examine how smoking status impacts adult perceptions and expectations of e-cigarettes. METHODS: We used Mechanical Turk (MTurk), a "crowdsourcing" platform, to rapidly survey a large (n = 796; female = 381; male = 415), diverse sample of adult ever (44%) and never smokers (56%), including ever (28%) and never (72%) users of e-cigarettes. RESULTS: Smokers and non-smokers learned about e-cigarettes primarily through the internet and conversations with others. Ever smokers were more likely than never smokers, and female current smokers were more likely than female former smokers, to have learned about e-cigarettes from point of sale advertising (p's < 0.05) and to believe that e-cigarettes help smokers quit (ps < 0.05). Among never users of e cigarettes, current smokers were more likely than never smokers and former smokers to report that they would try e-cigarettes in the future (ps < 0.01). Current smokers' top reason for wanting to try e-cigarettes was to quit or reduce smoking (56%), while never and former smokers listed curiosity. In contrast, female current smokers' top reason for not trying e-cigarettes was health and safety concerns (44%) while males were deterred by expense (44%). CONCLUSIONS: Adult smokers and non-smokers have different perceptions and expectations of e cigarettes. Public health messages regarding e-cigarettes may need to be tailored separately for persons with and without a history of using conventional cigarettes. Tailoring messages by gender within smoker groups may also improve their impact. PMID- 27712127 TI - Quantifying pupillary asymmetry through objective binocular pupillometry in the normal and mild traumatic brain injury (mTBI) populations. AB - INTRODUCTION: Little is known about human inter-ocular pupillary asymmetry (IOPA). Thus, the purpose of the present investigation was to assess objectively static and dynamic IOPA in normals and in individuals with mild traumatic brain injury (mTBI). METHODS: The pupillary light reflex (PLR) was assessed in an adult population of normals and in those with mTBI using the Neuroptics DP-2000 binocular pupillometer. Four stimulus conditions were used to optimize the assessment. Two aspects of the pupil were assessed: baseline diameter prior to light stimulation and the dynamic amplitude of constriction following light stimulation. RESULTS: There was no statistical difference in either the static or dynamic IOPA between the two groups. Thus, the data were combined for a better global parameter estimate. The mean average static IOPA was 0.26 mm (SD = +/- 0.20 mm) or 4.17% (+/- 3.29%). The mean average dynamic IOPA was dependent on the light stimulus condition, with the average across all four test conditions being 0.11 mm (+/- 0.10 mm) or 1.84% (+/- 1.70%). DISCUSSION: The inter-ocular pupillary effects of mTBI appear to be symmetrical rather than asymmetrical in nature. The findings provide clinicians and researchers a useful quantitative guideline to assess normal vs abnormal static and dynamic inter-ocular pupillary asymmetry (IOPA) in these two populations. PMID- 27712124 TI - Leveraging allostery to improve G protein-coupled receptor (GPCR)-directed therapeutics: cannabinoid receptor 1 as discovery target. AB - INTRODUCTION: Allosteric modulators of G-protein coupled receptors (GPCRs) hold the promise of improved pharmacology and safety over typical orthosteric GPCR ligands. These features are particularly relevant to the cannabinoid receptor 1 (CB1R) GPCR, since typical orthosteric CB1R ligands are associated with adverse events that limit their translational potential. Areas covered: The contextual basis for applying allostery to CB1R is considered from pharmacological, drug discovery, and medicinal standpoints. Rational design of small-molecule CB1R allosteric modulators as potential pharmacotherapeutics would be greatly facilitated by direct experimental characterization of structure-function correlates underlying the biological activity of chemically-diverse CB1R allosteric modulators, CB1R allosteric ligand-binding binding pockets, and amino acid contact residues critical to allosteric ligand engagement and activity. In these regards, designer covalent probes exhibiting well-characterized molecular pharmacology as CB1R allosteric modulators are emerging as valuable molecular reporters enabling experimental interrogation of CB1R allosteric site(s) and informing the design of new CB1R agents as drugs. Expert opinion: Synthesis and pharmacological profiling of CB1R allosteric ligands will continue to provide valuable insights into CB1R structure-function correlates. The resulting data should expand the repertoire of novel agents capable of exerting therapeutic benefit by modulating CB1R-dependent signaling. PMID- 27712129 TI - Corrigendum. PMID- 27712128 TI - Association between Q192R paraoxonase 1 polymorphism and serumadipocyte-fatty acid binding protein (FABP4) levels in Mexican women. AB - AIM: This study aimed to evaluate the genetic effects of PON1 Q192R polymorphism on serum FABP4 levels in Mexican women. METHODS: PON1 Q192R polymorphism was genotyped using a TaqMan allelic discrimination assay and serum FABP4 concentration was measured using an enzyme-linked immunosorbent assay. RESULTS: The distribution of genotype frequencies in the assessed women (PON1 Q192R polymorphism) was QQ = 20%, QR = 48% and RR = 32%. Significantly higher serum FABP4 levels were found in women with genotype QR/RR (20.6 +/- 2.20 ng/mL), when compared with the levels found in the QQ group (12.8 +/- 1.70 ng/mL) (p = .004). After, the odds ratio (OR) was calculated by binomial logistic regression analysis and a significantly higher OR was found in the QR/RR group when compared with the QQ group (OR = 3.45; 95% CI = 1.80-16.50; p < .05). CONCLUSION: The results support an association between 192R-allele of the PON1 polymorphism (Q192R) and increased serum FABP4 levels (suggested as an early biomarker of CVDs risk) in assessed Mexican women. PMID- 27712130 TI - Serum levels of second-generation antipsychotics are associated with cognitive function in psychotic disorders. AB - OBJECTIVES: Antipsychotics are effective in treating psychosis and mood episodes; however, the effect on cognition is less known. We investigated the association between serum levels of second-generation antipsychotics (SGAs) and cognitive performance in psychosis spectrum disorders in a naturalistic setting. METHODS: A total of 495 patients with a DSM-IV Schizophrenia and Other Psychotic Disorders (SCZ, n = 373) or Bipolar Disorder (BD, n = 122) diagnosis treated with olanzapine, quetiapine, aripiprazole or risperidone were tested neuropsychologically with concurrent measurement of the serum concentration of the drug. Linear regression was used for association analyses. RESULTS: Attention was positively associated with the olanzapine concentration (standardised beta (beta) coefficient = 0.19, P = .006), and short-term verbal memory and verbal fluency were negatively associated with the quetiapine (beta = -0.24, P = .004) and risperidone (beta = -0.37, P = .007) concentrations respectively. CONCLUSIONS: The present results suggest that SGA serum concentration is associated with better attention (small effect size), and worse verbal memory (small effect size) and verbal fluency (medium effect size). These findings are in line with the notion that SGAs affect aspects of cognitive function, and suggest careful dosing in patients with severe memory and executive problems. PMID- 27712131 TI - Sudden sensorineural hearing loss: is there a relationship between routine haematological parameters and audiogram shapes? AB - OBJECTIVE: To investigate the relationship between haematological routine parameters and audiogram shapes in patients affected by sudden sensorineural hearing loss (SSNHL). DESIGN: A retrospective study. All patients were divided into four groups according to the audiometric curve and mean values of haematological parameters (haemoglobin, white blood cell, neutrophils and lymphocytes relative count, platelet count, haematocrit, prothrombin time, activated partial thromboplastin time, fibrinogen and neutrophil-to-lymphocite ratio) of each group were statistically compared. The prognostic role of blood profile and coagulation test was also examined. STUDY SAMPLE: A cohort of 183 SSNHL patients without comorbidities. RESULTS: With a 48.78% of complete hearing recovery, individuals affected by upsloping hearing loss presented a better prognosis instead of flat (18.36%), downsloping (19.23%) and anacusis (2.45%) groups (p = 0.0001). The multivariate analysis of complete blood count values revealed lower mean percentage of lymphocytes (p = 0.041) and higher platelet levels (p = 0.015) in case of downsloping hearing loss; with the exception of fibrinogen (p = 0.041), none of the main haematological parameters studied resulted associated with poorer prognosis. CONCLUSIONS: Our work suggested a lack of association between haematological parameters and a defined audiometric picture in SSNHL patients; furthermore, only fibrinogen seems to influence the prognosis of this disease. PMID- 27712132 TI - Diagnostic utility of the HIV dementia scale and the international HIV dementia scale in screening for HIV-associated neurocognitive disorders among Spanish speaking adults. AB - Given that neurocognitive impairment is a frequent complication of HIV-1 infection in Spanish-speaking adults, the limited number of studies assessing HIV associated neurocognitive disorders (HAND) in this population raises serious clinical concern. In addition to being appropriately translated, instruments need to be modified, normed, and validated accordingly. The purpose of the current study was to examine the diagnostic utility of the HIV Dementia Scale (HDS) and International HIV Dementia Scale (IHDS) to screen for HAND in Spanish-speaking adults living with HIV infection. Participants were classified as either HAND (N = 47) or No-HAND (N = 53) after completing a comprehensive neuropsychological evaluation. Receiver operating characteristic analyses found the HDS (AUC = .706) was more sensitive to detecting HAND than the IHDS (AUC = .600). Optimal cutoff scores were 9.5 for the HDS (PPV = 65.2%, NPV = 71.4%) and 9.0 for the IHDS (PPV = 59.4%, NPV = 59.1%). Canonical Correlation Analysis found the HDS converged with attention and executive functioning. Findings suggest that while the IHDS may not be an appropriate screening instrument with this population, the HDS retains sufficient statistical validity and clinical utility to screen for HAND in Spanish-speaking adults as a time-efficient and cost-effective measure in clinical settings with limited resources. PMID- 27712133 TI - EEG Derived Brain Activity Reflects Treatment Response from Vagus Nerve Stimulation in Patients with Epilepsy. AB - The mechanism of action of vagus nerve stimulation (VNS) is yet to be elucidated. To that end, the effects of VNS on the brain of epileptic patients were studied. Both when VNS was switched "On" and "Off", the brain activity of responders (R, seizure frequency reduction of over 50%) was compared to the brain activity of nonresponders (NR, seizure frequency reduction of less than 50%). Using EEG recordings, a significant increase in P300 amplitude for R and a significant decrease in P300 amplitude for NR were found. We found biomarkers for checking the efficacy of VNS with accuracy up to 94%. The results show that P300 features recorded in nonmidline electrodes are better P300 biomarkers for VNS efficacy than P300 features recorded in midline electrodes. Using source localization and connectivity analyses, the activity of the limbic system, insula and orbitofrontal cortex was found to be dependent on VNS switched "On" versus "Off" or patient group (R versus NR). The results suggest an important role for these areas in the mechanism of action of VNS, although a larger patient study should be done to confirm the findings. PMID- 27712134 TI - Dietary calcium intake is inversely associated with blood pressure in Brazilian children. AB - This study aimed to evaluate the dietary calcium intake and its association with blood pressure in childhood. It is a cross-sectional study with a sample of 347 Brazilian children aged 8 and 9 years. We evaluated calcium intake through three dietary records. Blood pressure was measured following the recommendations of the Brazilian Society of Cardiology. The intake of calcium was below recommendations for almost all children (96.3%). There was statistically significant difference in the means of systolic (p = .041) and diastolic (p = .047) blood pressure in the tertiles of calcium intake. After adjustment of regression model, each tertile of calcium intake showed that the systolic and diastolic blood pressure was reduced in 1.53 (95% confidence interval: -2.84 to -0.21) and 1.83 mmHg (95% confidence interval: -3.49 to -0.19), respectively. Our results showed an inverse association between dietary calcium intake and blood pressure in childhood. PMID- 27712135 TI - Functional assessment of autologous platelet-rich plasma (PRP) after long-term storage at -20 degrees C without any preservation agent. AB - BACKGROUND: Platelet-rich plasma (PRP) is increasingly being used in the treatment of chronic wounds, pathologies of the musculoskeletal system, and in cosmetic medicine; however, the preparation of platelet-rich plasma is both time consuming and requires invasive intervention. Additional costs are introduced if special equipment is used during preparation. The aim of the present study is to test whether autologous platelet-rich plasma (PRP) preserves the feature of growth factor release when stored at -20 degrees C after preparation. METHOD: Autologous PRP concentrates were prepared using whole blood samples obtained from 20 healthy subjects and divided into three parts to form three groups. Epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), platelet derived growth factor-AB (PDGF-AB), insulin-like growth factor 1 (IGF-1), transforming growth factor-beta (TGF-beta), and P-Selectin levels were immediately analysed in the control group. The other groups were defined as the experimental groups and were stored at -20 degrees C and analysed on the 7th and the 14th days. The same growth factors were tested in the experimental groups. RESULTS: The growth factors (EGF, VEGF, PDGF-AB, IGF-1, TGF-beta) and P-selectin levels were significantly decreased in the autologous PRP samples stored at -20 degrees C compared to the control group. CONCLUSION: The growth factor levels on days 7 and 14 suggest that autologous PRP can be stored at -20 degrees C without preservative agents, although in vivo studies are required in order to evaluate the clinical efficacy of the detected growth factor levels. PMID- 27712136 TI - Association between the variability of the ABCA13 gene and the risk of major depressive disorder and schizophrenia in the Han Chinese population. AB - OBJECTIVES: The ATP-binding cassette transporter superfamily is one of the largest membrane protein families, which is responsible for transportation of substances across the membranes by utilising energy. Some research has bridged the variations in ABCA13 with occurrence of psychiatric disorders. To investigate the overlapping risk conferred by ABCA13 for both major depressive disorder and schizophrenia, we analysed tag single nucleotide polymorphisms (tag SNPs). METHODS: We used TaqMan(r) technology to genotype 1045 major depressive disorder patients, 1235 schizophrenia patients and 1235 healthy controls of Han Chinese origin. RESULTS: We found that rs7789493 (Pallele = 7.23E-04, Pgenotype =.001) was associated with major depressive disorder, while rs17132388 (Pallele = 1.63E 04, Pgenotype = 7.50E-04) and rs6583476 (Pallele = 5.50E-04, Pgenotype =.002) showed statistically significant association with schizophrenia. CONCLUSIONS: Our results indicate that the ABCA13 gene may contain overlapping common genetic risk factors for both major depressive disorder and schizophrenia in the Han Chinese population. The study on variants conferring overlapping risk for multiple psychiatric disorders could be tangible pathogenesis support in clinical or diagnostic references. PMID- 27712139 TI - Louise Crosby.

PMID- 27712137 TI - An update on the management of urinary tract infections in the era of antimicrobial resistance. AB - Urinary tract infections (UTIs) caused by antibiotic-resistant Gram-negative bacteria are a growing concern due to limited therapeutic options. Gram-negative bacteria, specifically Enterobacteriaceae, are common causes of both community acquired and hospital acquired UTIs. These organisms can acquire genes that encode for multiple antibiotic resistance mechanisms, including extended-spectrum lactamases (ESBLs), AmpC- beta -lactamase, and carbapenemases. The assessment of suspected UTI includes identification of characteristic symptoms or signs, urinalysis, dipstick or microscopic tests, and urine culture if indicated. UTIs are categorized according to location (upper versus lower urinary tract) and severity (uncomplicated versus complicated). Increasing rates of antibiotic resistance necessitate judicious use of antibiotics through the application of antimicrobial stewardship principles. Knowledge of the common causative pathogens of UTIs including local susceptibility patterns are essential in determining appropriate empiric therapy. The recommended first-line empiric therapies for acute uncomplicated bacterial cystitis in otherwise healthy adult nonpregnant females is a 5-day course of nitrofurantion or a 3-g single dose of fosfomycin tromethamine. Second-line options include fluoroquinolones and beta-lactams, such as amoxicillin-clavulanate. Current treatment options for UTIs due to AmpC- beta lactamase-producing organisms include fosfomycin, nitrofurantion, fluoroquinolones, cefepime, piperacillin-tazobactam and carbapenems. In addition, treatment options for UTIs due to ESBLs-producing Enterobacteriaceae include nitrofurantion, fosfomycin, fluoroquinolones, cefoxitin, piperacillin-tazobactam, carbapenems, ceftazidime-avibactam, ceftolozane-tazobactam, and aminoglycosides. Based on identification and susceptibility results, alternatives to carbapenems may be used to treat mild-moderate UTIs caused by ESBL-producing Enterobacteriaceae. Ceftazidime-avibactam, colistin, polymixin B, fosfomycin, aztreonam, aminoglycosides, and tigecycline are treatment options for UTIs caused by carbapenem-resistant Enterobacteriaceae (CRE). Treatment options for UTIs caused by multidrug resistant (MDR)-Pseudomonas spp. include fluoroquinolones, ceftazidime, cefepime, piperacillin-tazobactam, carbapenems, aminoglycosides, colistin, ceftazidime-avibactam, and ceftolozane-tazobactam. The use of fluoroquinolones for empiric treatment of UTIs should be restricted due to increased rates of resistance. Aminoglycosides, colistin, and tigecycline are considered alternatives in the setting of MDR Gram-negative infections in patients with limited therapeutic options.

PMID- 27712141 TI - Expression and methylation of BDNF in the human brain in schizophrenia. AB - OBJECTIVES: To examine the combined effect of the BDNF Val66Met (rs6265) polymorphism and BDNF DNA methylation on transcriptional regulation of the BDNF gene. METHODS: DNA methylation profiles were generated for CpG sites proximal to Val66Met, within BDNF promoter I and exon V for prefrontal cortex samples from 25 schizophrenia and 25 control subjects. Val66Met genotypes and BDNF mRNA expression data were generated by transcriptome sequencing. Expression, methylation and genotype data were correlated and examined for association with schizophrenia. RESULTS: There was 43% more of the BDNF V-VIII-IX transcript in schizophrenia samples. BDNF mRNA expression and DNA methylation of seven CpG sites were not associated with schizophrenia after accounting for age and PMI effects. BDNF mRNA expression and DNA methylation were not altered by Val66Met after accounting for age and PMI effects. DNA methylation of one CpG site had a marginally significant positive correlation with mRNA expression in schizophrenia subjects. CONCLUSIONS: Schizophrenia risk was not associated with differential BDNF mRNA expression and DNA methylation. A larger age-matched cohort with comprehensive clinical history is required to accurately identify the effects of genotype, mRNA expression and DNA methylation on schizophrenia risk. PMID- 27712142 TI - Chronic obstructive airway disease among patients hospitalized with acute heart failure; clinical characteristics, precipitating factors, management and outcome: Observational report from the Middle East. AB - BACKGROUND: The purpose of this study was to report the prevalence, clinical characteristics, contributing factors, management and outcome of patients with chronic obstructive pulmonary disease (COPD) among patients hospitalized with heart failure (HF). METHODS: Data were derived from Gulf Care (Gulf acute heart failure registry), a prospective multicenter study of 5005 consecutive patients hospitalized with acute heart failure during February to November 2012 in seven Middle Eastern countries. Data were described and compared for demographics, management and outcomes. RESULTS: The prevalence of COPD among HF patients was 10%. COPD patients were older, more likely to be female and to have diabetes, hypertension, chronic kidney disease and sleep apnea (P = 0.001 for all) when compared to non-COPD patients. Contributing factors for hospitalization were systemic infection and atrial arrhythmias in COPD patients compared to acute coronary syndrome, uncontrolled hypertension and anemia in the non-COPD patients. Left-ventricular ejection fraction was higher in COPD patients; while BNP levels were comparable between the two groups. Non-invasive ventilation was used more frequently among COPD patients compared to non-COPD patients (P = 0.001). On multivariate logistic regression analysis, COPD was not associated with increased risk in-hospital and one-year death among acute heart failure (AHF) population and beta blockers treatment appear to have neutral mortality effect in COPD patients with HF. CONCLUSION: COPD have distinct cardiovascular risk profile and precipitating factors for hospitalization with HF when compared to non-COPD patients. COPD history had no impact on the short-term and one-year mortality. PMID- 27712143 TI - Mayo registry for telemetry efficacy in arrest (MR TEA) study: An assessment of the effect of admission diagnosis on outcomes from in-hospital cardiopulmonary arrest. AB - INTRODUCTION: Little data exists evaluating how different risk factors influence outcomes following in-hospital arrests. METHODS: A retrospective review of patients that suffered a cardiopulmonary arrest between 1 May 2008 and 30 June 2014 was performed. Patients were stratified into subsets based on cardiac versus non-cardiac reasons for admission. RESULTS: 199 patients met inclusion criteria, of which 138 (69.3%) had a non-cardiac reason for admission and 61 (30.7%) a cardiac etiology. No difference in demographics and non-cardiac comorbidities were present. Cardiac-related comorbidities were more prevalent in the cardiac etiology subset. Arrests with a shockable rhythm were more common in the cardiac group (P < 0.0001), yet return of spontaneous circulation from the index event was similar (P = 0.254). More patients in the cardiac group were alive at 24-h post resuscitation (n = 34, 55.7% versus n = 49, 35.5%; P = 0.0085), discharge (n = 21, 34.4% versus n = 19, 13.8%; P = 0.0018), and at last follow-up (n = 13, 21.3% versus n = 14, 10.1%; P = 0.0434). CONCLUSION: Although patients with cardiac and non-cardiac etiologies for admission have similar rates of return of spontaneous circulation, those with cardiac etiologies are more likely to survive to hospital discharge and outpatient follow-up.

PMID- 27712146 TI - Make the strategy a reality. AB - The National Dementia Strategy was published in February 2009 with the intention that dementia would be a national priority. Yet a year on, services for people with dementia still do not provide value for money.

The Department of Health is criticised, with a call for stronger leadership and joined up working between health and social care services for people with dementia. PMID- 27712147 TI - Alcohol Is alcohol misuse only a problem in the younger generation? AB - The popular image of older people requesting a small sherry with their Christmas lunch and becoming tipsy is an erroneous view of their drinking habits. People do not stop drinking hazardously simply because they are older. Bereavement, isolation and pain are a potent mix when combined with the low cost and accessibility of alcohol. It is likely therefore that there will be an increase in the need for alcohol services for older people. PMID- 27712144 TI - Regulation of fixLJ by Hfq Controls Symbiotically Important Genes in Sinorhizobium meliloti. AB - The RNA-binding chaperone Hfq plays critical roles in the establishment and functionality of the symbiosis between Sinorhizobium meliloti and its legume hosts. A mutation in hfq reduces symbiotic efficiency resulting in a Fix- phenotype, characterized by the inability of the bacterium to fix nitrogen. At least in part, this is due to the ability of Hfq to regulate the fixLJ operon, which encodes a sensor kinase-response regulator pair that controls expression of the nitrogenase genes. The ability of Hfq to bind fixLJ in vitro and in planta was demonstrated with gel shift and coimmunoprecipitation experiments. Two (ARN)2 motifs in the fixLJ message were the likely sites through which Hfq exerted its posttranscriptional control. Consistent with the regulatory effects of Hfq, downstream genes controlled by FixLJ (such as nifK, noeB) were also subject to Hfq regulation in planta.

AB - AlTHOUGH THIS book focuses predominantly on a lay carer's experiences of caring for a relative with dementia in the UK it would be suitable for health and social care staff likely to encounter people with dementia and their carers. It highlights the need for staff to think outside their comfort zones and look at the lived experience of dementia. PMID- 27712184 TI - Talking about death. AB - A narrative approach was used to engage older adults in conversation about death in general and their own death in particular. Comments such as 'I am 89 now, how many more years do I have' and 'I don't want to go, I love this life. But it doesn't bother me,' suggest that people's anxiety about dying and fear decrease with age. PMID- 27712185 TI - Risks of taking antidepressants.

AB - Developing successful tissue engineering strategies requires an understanding of how cells within an implanted scaffold interact with the host environment. The objective of this study was to use a computational mechanobiological model to explore how the design of a cell-laden scaffold influences the spatial formation of cartilage and bone within an osteochondral defect. Tissue differentiation was predicted using a previously developed model, in which cell fate depends on the local oxygen tension and the mechanical environment within a damaged joint. This model was first updated to include a rule through which mature cartilage was resistant to both terminal differentiation and vascularization, and then used to simulate osteochondral defect repair following the implantation of various cell free and cell-laden scaffolds. While delivery of a cell-free scaffold led to only marginal improvements in joint repair, implantation of a cell-laden bilayered scaffold was predicted to significantly increase cartilage formation in the chondral phase of the scaffold. Despite these improvements, bone still progressed into the chondral regions of these engineered implants by means of endochondral ossification during the later stages of repair. This led to thinning of the cartilage tissue, which in turn resulted in a prediction of increased tissue strain and, eventually, increases in fibrocartilage formation as a result of this altered mechanical stimulus. In contrast to this, the model predicted that implantation of a trilayered scaffold, which included a compact layer to confine angiogenesis to the osseous phase of the defect, further improves joint regeneration. This is achieved by allowing chondrogenically primed mesenchymal stem cells, which are seeded into the chondral phase of the implant, to form stable cartilage, which was ultimately resistant to both vascularization and endochondral ossification. These models provide a framework for exploring how environmental factors impact bone, cartilage, and joint regeneration and can be used to inform the design of new tissue engineering strategies for use in orthopedic medicine. PMID- 27712194 TI - Exercise-induced hypoalgesia: Pain tolerance, preference and tolerance for exercise intensity, and physiological correlates following dynamic circuit resistance exercise. AB - Previous research has demonstrated significant decreases in pain perception in healthy individuals following both aerobic and upper body resistance exercise, but research on circuit training has been limited. The purpose of the study was to determine the effects of a strenuous bout of dynamic circuit resistance exercise on pain threshold and pain tolerance in conjunction with changes in blood lactate levels, heart rate (HR), and perceived exertion. A sample of 24 college-age students participated in 2 sessions: (1) a maximal strength testing session and (2) a circuit training bout of exercise that consisted of 3 sets of 12 repetitions with a 1:1 work to rest ratio at 60% one-repetition maximum (1-RM) predicted from a three-repetition maximum (3-RM) for 9 exercises. Participants exhibited increases in pain tolerance, blood lactate levels, HR and perceived exertion following resistance exercise. Preference for exercise intensity was positively correlated with lactate post exercise and tolerance for exercise intensity was positively correlated with pain tolerance and lactate post exercise. In conclusion, this is the first study to demonstrate increases in pain tolerance following a dynamic circuit resistance exercise protocol and disposition for exercise intensity may influence lactate and pain responses to circuit resistance exercise. PMID- 27712195 TI - Information theoretic sub-network mining characterizes breast cancer subtypes in terms of cancer core mechanisms. AB - A breast cancer subtype classification scheme, PAM50, based on genetic information is widely accepted for clinical applications. On the other hands, experimental cancer biology studies have been successful in revealing the mechanisms of breast cancer and now the hallmarks of cancer have been determined to explain the core mechanisms of tumorigenesis. Thus, it is important to understand how the breast cancer subtypes are related to the cancer core mechanisms, but multiple studies are yet to address the hallmarks of breast cancer subtypes. Therefore, a new approach that can explain the differences among breast cancer subtypes in terms of cancer hallmarks is needed. We developed an information theoretic sub-network mining algorithm, differentially expressed sub network and pathway analysis (DeSPA), that retrieves tumor-related genes by mining a gene regulatory network (GRN) of transcription factors and miRNAs. With extensive experiments of the cancer genome atlas (TCGA) breast cancer sequencing data, we showed that our approach was able to select genes that belong to cancer core pathways such as DNA replication, cell cycle, p53 pathways while keeping the accuracy of breast cancer subtype classification comparable to that of PAM50. In addition, our method produces a regulatory network of TF, miRNA, and their target genes that distinguish breast cancer subtypes, which is confirmed by experimental studies in the literature. PMID- 27712196 TI - Identifying cancer type specific oncogenes and tumor suppressors using limited size data. AB - Cancer is a complex and heterogeneous genetic disease. Different mutations and dysregulated molecular mechanisms alter the pathways that lead to cell proliferation. In this paper, we explore a method which classifies genes into oncogenes (ONGs) and tumor suppressors. We optimize this method to identify specific (ONGs) and tumor suppressors for breast cancer, lung adenocarcinoma (LUAD), lung squamous cell carcinoma (LUSC) and colon adenocarcinoma (COAD), using data from the cancer genome atlas (TCGA). A set of genes were previously classified as ONGs and tumor suppressors across multiple cancer types (Science 2013). Each gene was assigned an ONG score and a tumor suppressor score based on the frequency of its driver mutations across all variants from the catalogue of somatic mutations in cancer (COSMIC). We evaluate and optimize this approach within different cancer types from TCGA. We are able to determine known driver genes for each of the four cancer types. After establishing the baseline parameters for each cancer type, we identify new driver genes for each cancer type, and the molecular pathways that are highly affected by them. Our methodology is general and can be applied to different cancer subtypes to identify specific driver genes and improve personalized therapy.

PMID- 27712198 TI - Performance and physiological effects of different descending strategies for cross-country mountain biking. AB - This study investigated the performance-related feasibility and physiological benefits of purposefully eliminating propulsive work while descending in mountain biking and compared values to those measured during road descending. Participants cycled uphill on a road at race pace before descending over three conditions (off road pedalling; off-road coasting; road coasting). Relatively low power output during off-road pedalling was associated with a greater oxygen uptake (p < .01) when compared with off-road coasting despite no difference in vibration exposure (p > .05). Importantly, pedalling did not invoke a performance benefit (p > .05) on the descent used in this study. Significantly greater heart rate and oxygen uptake (both p < .01) were observed between road and off-road descending, likely caused by the increase in terrain-induced vibrations (p < .01) experienced between the bicycle and rider. Results indicate that reducing propulsive work during descending can improve recovery without being disadvantageous to performance. Similarly, the vibrations experienced during road descending are relatively low, and further reduce oxygen cost. In an effort to increase efficiency, it is recommended that mountain bike athletes focus on skills to increase descending speed without the addition of pedalling, and that equipment be used to decrease vibrations nearer to those seen on the road.

AB - In Italy, no specific recommendation toward maternal pertussis immunization during pregnancy has been issued. However, vaccination during pregnancy will be likely integrated in the Italian immunization program in the future. In order to identify barriers to achieving a sufficient vaccination coverage during pregnancy, we investigated knowledge, attitude and practice toward pertussis vaccination during pregnancy through a web-based survey. A total of 343 Italian pregnant women (N = 164) and women in the postpartum period (N = 183) completed the online questionnaire. More than a half of the study population was uncertain regarding the benefits of the vaccination during pregnancy. Only 1.7% of women in the postpartum had received the vaccination during pregnancy, and 21% of pregnant women declared the intention to be vaccinated in pregnancy. Only 34% would accept the vaccination in the current or in a future pregnancy, if recommended by a physician, and a half would remain uncertain. Perceiving the vaccine as harmful for the fetus' development is associated to a decreased willingness to be vaccinated if recommended by a HCP, both in pregnant women (OR 0.25 p = 0.010 95% CI 0.09-0.72) and in women in the postpartum period (OR 0.32 p = 0.006 95% CI 0.15-0.72). Our study suggests that the vaccination recommendation by physicians might not be sufficient to adequately raise vaccination coverage against pertussis among Italian pregnant women. A combination of educational interventions and tailored communi-cation campaigns could be implemented to promote maternal immunization. PMID- 27712244 TI - Letter from the editor.

This paper presents 760 challenges which 330 NHS staff reported as preventing the delivery of effective, high quality and safe care. Some problems have been known for over 25 years (staff shortages, finance and patient complexity) but other challenges raise questions about the commitment of the NHS to patient and staff safety. For example, Organisational Culture leading to 'stifling bureaucracy', 'odds stacked against smooth [...] working' and Workload resulting in 'firefighting daily' and 'perpetual crisis mode'. The role of Human Factors/Ergonomics professional input (engagement with safety scientists) is discussed in the context of success stories and examples of Human Factors Integration from other safety critical industries (Defence, Nuclear and Rail). Practitioner Summary: 760 challenges to the quality, effectiveness and safety of health care were identified at Human Factors/Ergonomics taster workshops in England. These are used to challenge health care providers to think about a Human Factors Integration (HFI systems) approach for safety, well-being and performance for all people involved in providing and receiving health care.

AB - Aim To develop and evaluate the use of a specific picture book aiming to prepare children for anaesthesia and surgery. Methods An intervention comparing two different information methods before ear, nose and throat day surgery was performed. The intervention involved using a specific information sheet and a specific picture book. Parents (n=104) of children aged 2-12 years completed open ended questions that were analysed with qualitative content analysis. They were divided into two groups: one group received routine information and one received routine information and the intervention. Findings The picture sheet and picture book were valuable aids to prepare small children for anaesthesia and surgery by explaining the procedures that would take place. The parents expressed that knowledge of the procedures made them and the child feel secure. Conclusion Peri operative information through pictures supports children and their parents during day surgery and may be helpful in future healthcare visits.

AB - In England last year, nearly 40,000 babies and young children with bronchiolitis were admitted to hospital. This infection is usually caused by the respiratory syncytial virus, and in most cases symptoms are mild and last only a few days. However, a quality standard published in the summer by the National Institute for Health and Care Excellence (NICE) states that admissions for bronchiolitis are rising. NICE quality standards describe high-priority areas for improvement in a defined field of care.

It also discusses the effects of CF on the patient and her family, and how it affects their quality of life and well-being. PMID- 27712326 TI - Nurse-initiated and criteria-led discharge from hospital for children and young people. AB - The readiness of a child or young person for discharge includes patient safety, the family's ability to care for the child at home and the ongoing treatment they will need, which has a direct influence on their health outcomes and future readmissions to hospital. There are no standard criteria for discharge practice and registered nurses have reported concerns about their ability to provide education and discharge planning to meet the needs of the patient and their family. A literature review was carried out to ascertain the current discharge principles adhered to in practice and the implemented tools used. The problems faced by registered nurses include ineffective communication, poorly defined role in discharge planning and lack of agreement with the multidisciplinary team. The standardisation of discharge procedures may reduce the risk of readmission and health deterioration of the patient and ensure positive health outcomes, improve family health literacy and continuity of care.

PMID- 27712327 TI - Understanding the endocrinopathies associated with the treatment of childhood cancer: part 1. AB - This article explores endocrinopathies associated with late effects of treatments for childhood cancers. It is the first of two articles on the subject, the second to be published in November. This is a growing area of care, as more than 80% of all childhood cancer is treatable, resulting in an increase in survivors of childhood cancer. However, up to two thirds of these children are reported to present with significant health problems resulting from their treatments, and approximately 25% of survivors have endocrine problems. This article explains how an understanding of oncology and endocrinology enables nurse specialists to educate young people about their past treatment and its implications for their health. This knowledge is the foundation for individually-tailored care plans that enable young people to be confident to self-care and self-monitor their long term health.

While appropriate theoretical insights are provided the emphasis is on practical application and the book is particularly useful in this regard. PMID- 27712350 TI - Meta-analyses of clinical neuropsychological tests of executive dysfunction and impulsivity in alcohol use disorder. AB - BACKGROUND: Promising models for cognitive rehabilitation in alcohol treatment rest on a more nuanced understanding of the associated impairments in the multifaceted domains of executive functioning (EF) and impulsivity. OBJECTIVES: This meta-analysis examined the effects of alcohol on the individual subcomponents of EF and impulsivity in recently detoxified participants, including 1) Inhibition & Self-Regulation, 2) Flexibility & Set Shifting, 3) Planning & Problem Solving, 4) Reasoning & Abstraction, and 5) Verbal Fluency. Impulsivity was further examined through an analysis of motor, cognitive, and decisional subcategories. METHOD: Investigators searched, coded, and calculated effect sizes of impairments demonstrated in a broad range of neuropsychological tests for EF. A total of 77 studies were selected covering 48 years of research with a sample size of 5140. RESULTS: Findings ranged from a Hedges' g effect size of 0.803 for Inhibition to a Hedges' g of 0.359 for Verbal Fluency. Results also varied for the individual subcategories of Inhibition, including a large effect size for decisional impulsivity (g = 0.817) and cognitive impulsivity (0.860), and a moderate effect size for motor impulsivity (g = 0.529). The Hayling Test, Wisconsin Card Sorting Test, and Iowa Gambling Task were the measures most sensitive for alcohol effects. CONCLUSION: Planning, problem solving, and inhibitory abilities are significantly affected by alcohol abuse, with decisional and cognitive forms of impulsivity most impacted. Cognitive remediation targeting these deficits might increase the related functions that mediate the ability to moderate or abstain from alcohol, and so lead to improved treatment results.

AB - How older women cope with challenges and losses in later life influences not only their physical health, but also their psychological wellbeing and quality of life. The Red Hat Society is an international social group for women over 50, and has a mission to 'celebrate the silliness of life'; the main feature of society's meetings is that members must dress up in gaudy red hats and garish purple outfits. The women interviewed said participation helped them to cope with emotional stressors of later life. Although growing old is not something that can be changed, participation in the society helps circumstances seem less distressing and more manageable. PMID- 27712362 TI - One chance to get it right.

The charity, which offers care services for older people in residential accommodation and their own homes across the South West, has developed a specialist dementia care programme. Maureen Howe, who spearheaded the training programme, said: 'Although the standard of care within our care homes was good, we wanted to be much better at meeting the needs of people living with a dementia. We wanted to change the culture of care from being task-based to person-centred, seeing each resident for the unique person they are. The training was for everyone, not just the care staff so it encompassed admin, laundry staff, catering staff, everyone.' PMID- 27712366 TI - Early discharge fuels A&E visits.

AB - Link nurses should have background knowledge of palliative care, be able to support and develop others and be in a position to implement change. This paper explored link nurses' views of supports and barriers to implementation of the role in the nursing home. The nurses found external support, monthly meetings and access to a resource file helpful but were hindered by lack of management support, a transient workforce and lack of preparation for the role.

They are calling for the government to cancel plans to raise the income threshold for eligibility for nursing care assistance, as they say this could deprive 30,000 senior citizens of home help. PMID- 27712373 TI - The four-hour waiting target in A&E is not always helping older people. AB - The Department of Health document, The NHS Plan, stated that no patient should wait more than four hours in Accident and Emergency (A&E). Nurses argue that the pressures of meeting the four-hour target have led to hasty transfers to other departments, often with incomplete assessments and misdiagnosis. Transferring patients in this manner poses problems for the ward and for the older person, particularly those with dementia who are further disorientated by multiple moves. PMID- 27712374 TI - Scientific approach to nursing recommended.

AB - Oral hygiene care reduces risk of pneumonia three-fold Good oral hygiene can prevent death from pneumonia, according to a new study from the US National Institute of Dental and Craniofacial Research in Bethesda, Maryland. Pneumonia is the leading cause of death in older nursing home residents, and is often triggered by aspirating saliva or food. However, analysis of medical records of 143 older people in a nursing home showed that the help of a certified nursing assistant assigned to provide oral hygiene care reduced the risk of dying from pneumonia three-fold.

AB - Numbers of older people with schizophrenia are likely to increase with the ageing population and they require special attention when considering care and treatment. Medication is the mainstay of treatment for patients with schizophrenia, to control hallucinations and delusions. Older people are more prone to the adverse effects of antipsychotic medication, particularly torso movements and buccal twitches. They are also more likely to be prescribed inappropriate doses and types of medication. Where drugs are required, smaller doses should be prescribed. PMID- 27712380 TI - Australia.

AB - You never see TV advertisements about dementia care services, perhaps because there are more buyers than sellers, and providers have all the business they can cope with. But Bupa has changed that with an ad that it claims is the first one ever on offering care for people with dementia. PMID- 27712385 TI - Act now, save later. AB - The second interim report evaluating 29 local authority-led pilot schemes, known as POPPs (Partnerships for Older People Projects), presents encouraging news on their performance ( PSSRU 2008 ). These projects have been established for two years with funding from the Department of Health. The first phase - 19 projects - started in 2006, with the remainder a year later.

PMID- 27712390 TI - If nurses feel they are poorly treated by management it affects care. AB - This study found that nurses' time pressure and their perceptions of unfair management contribute to the prevalence of anti-anxiety or hypnotic drug use and pressure ulcers, even when controlling for nurse staffing levels. Where employees perceive that they are being treated unfairly there is reduced commitment and lack of involvement as well as increased staff health problems. Nurses' perception of unfairness may reflect a failure to engage nurses in decisions about use of anti-anxiety or hypnotic drugs and an under-use of nurses' expertise on the daily care needs of residents. Long-term care units should review work loads and management practices to support effective communication and collaboration among nursing staff. PMID- 27712389 TI - Study suggests geriatric patients should have pulse oximetry at night. AB - Older people have lower oxygen retention in the supine position during sleep.

AB - This article defines three levels of personhood: ? Biological personhood: Central to biological system is sentience or the ability to experience pleasure or pain. There is little disagreement that all individuals living with dementia retain personhood at a basic biological level. ? Individual personhood: This relates to an individual's characteristics including such things as the past, roles, personality, values, self-worth and spirituality. ? Sociological personhood: This is defined by the perceptions of society and other people's approach to the person with dementia. As social contacts become aware of cognitive decline, their behaviour towards the individual begins to change. Residents become more isolated and sociological personhood is threatened. Individuals living in nursing homes can become increasingly socially isolated. PMID- 27712392 TI - Exercise and weight loss are key to treating osteoarthritis. AB - Osteoarthritis is the most common joint disease and a leading cause of pain and disability in older people. Joint replacement for osteoarthritis of the hip is the only intervention with a large effect, but is only appropriate for patients with advanced disease. There is evidence that topical application of non steroidal anti-inflammatory drugs (NSAIDs) is helpful. Although less effective in pain relief, oral paracetamol should be tried before oral NSAIDs as it has a lower risk of side effects. Some long-used treatments, such as arthroscopic debridement and glucosamine, are now thought to be ineffective. PMID- 27712393 TI - A whole-systems approach for dementia careDrawing on his 30 years' experience as a nurse, Trevor Adams has written a book on dementia care nursing. Here, he refers to its contents to explain why nurses should look beyond person-centred and relationship-centred care to consider wider social, psychological and biological systems that help construct a more rounded picture of the needs of people with dementia. AB - The nursing care of people with dementia is carried out mainly by general and mental health nurses, and takes place in a wide variety of settings such as accident and emergency units, orthopaedic wards, people's homes, long- stay wards and day hospitals ( care Services Improvement Partnership (CSIP) 2005 ). My own experience of nursing people with dementia is as a mental health nurse, but my mother developed dementia and this has enabled me to see dementia care nursing from a different angle. PMID- 27712395 TI - Age no indicator of cancer survival. AB - Age is not a key factor in cancer survival, according to a team of researchers in Spain. And although 60 per cent of cancers occur in patients over 65, most clinical trials still exclude older people. This makes it difficult to predict how older people will respond to new cancer treatments. PMID- 27712394 TI - The right place to die. AB - The government's end-of-life care strategy aims to help people have a dignified death in the place of their choosing. For many people this means dying in the place where they have lived - at home. 'Is It That Time Already?', a new report by Housing 21, the older people's housing and care organisation, and the National End-of-Life Care programme, suggests that older people who live in extra care housing may be denied this choice because extra care housing is not recognised as a 'home for life'. PMID- 27712396 TI - First TV ad for dementia care. AB - Last month, viewers saw the first-ever TV advertisement about providing care for people with dementia. Screened as part of Bupa's initiative, bringing the issue of dementia care 'out of the shadows,' the ad features Ernie visiting his sister June, who has dementia, in a Bupa care home and shows the personalised care being delivered by specially trained staff. PMID- 27712398 TI - Nurses address winter's effect on ill health. AB - Nurses in the West Midlands have developed an award-winning scheme which aims to combat the effects of cold, damp weather on ill health. They identify patients whose health could be worsened by poor heating conditions, for example, those with asthma, angina, osteoporosis, or those recovering from surgery, and help them access grants and other funds to pay for heating and insulation improvements.

That's because the 83-year-old resident of a Bupa nursing home in Wilmslow, Cheshire, has had her festive design (inset) chosen from 200 entries to be the company's Christmas card for 2008. Joan has enjoyed painting from an early age and runs a weekly art class for other residents at the home. Bupa is the largest operator of care homes for older people in the UK and runs 304 nursing and residential homes with more than 21,000 registered beds - more than 25 per cent of which are registered for specialist dementia care. PMID- 27712401 TI - Longitudinal quantitative research designs. AB - In this paper I aim to present some of the advantages and problems associated with longitudinal quantitative research designs. The main feature of longitudinal designs is that the effect of time on the subjects of the research can be studied better than in cross-sectional designs where several groups (called cohorts), or one cohort divided up on the basis of a feature such as age, may be required. If you compare two groups on the basis of age you cannot assume that any differences you observe are due to age - this is known as the cohort effect. However, longitudinal designs bring some problems in terms of keeping subjects in the study and the longer the time between points at which stages of the study are carried out, the greater the difficulty in retaining subjects. In addition to these general features of longitudinal quantitative research designs, some specific designs and methods of statistical analysis will be considered. PMID- 27712403 TI - Editorial. AB - Writing for publication can be a tricky business. Finding the time, finding the words, submitting your work to be disfigured by the sharp red pens of reviewers and editors, and doing a day job at the same time, can conspire to deter even the most motivated and diligent potential author. However, and at risk of boring you on a topic that has probably been done to death, writing for publication is an important issue. Especially for researchers. So important in fact, that at the Workgroup of European Nurse Researchers (WENR) conference in Helsinki earlier in July scientific writing featured heavily in workshops and symposia. PMID- 27712399 TI - Priming Equine Bone Marrow-Derived Mesenchymal Stem Cells with Proinflammatory Cytokines: Implications in Immunomodulation-Immunogenicity Balance, Cell Viability, and Differentiation Potential. AB - Mesenchymal stem cells (MSCs) have a great potential for treating equine musculoskeletal injuries. Although their mechanisms of action are not completely known, their immunomodulatory properties appear to be key in their functions. The expression of immunoregulatory molecules by MSCs is regulated by proinflammatory cytokines; so inflammatory priming of MSCs might improve their therapeutic potential. However, inflammatory environment could also increase MSC immunogenicity and decrease MSC viability and differentiation capacity. The aim of this study was to assess the effect of cytokine priming on equine bone marrow derived MSC (eBM-MSC) immunoregulation, immunogenicity, viability, and differentiation potential, to enhance MSC immunoregulatory properties, without impairing their immune-evasive status, viability, and plasticity. Equine BM-MSCs (n = 4) were exposed to 5 ng/mL of TNFalpha and IFNgamma for 12 h (CK5-priming). Subsequently, expression of genes coding for immunomodulatory, immunogenic, and apoptosis-related molecules was analyzed by real-time quantitative polymerase chain reaction. Chromatin integrity and proliferation assays were assessed to evaluate cell viability. Trilineage differentiation was evaluated by specific staining and gene expression. Cells were reseeded in a basal medium for additional 7 days post-CK5 to elucidate if priming-induced changes were maintained along the time. CK5-priming led to an upregulation of immunoregulatory genes IDO, iNOS, IL-6, COX-2, and VCAM-1. MHC-II and CD40 were also upregulated, but no change in other costimulatory molecules was observed. These changes were not maintained 7 days after CK5-priming. Viability and differentiation potential were maintained after CK5-priming. These findings suggest that CK5-priming of eBM MSCs could improve their in vivo effectiveness without affecting other eBM-MSC properties. PMID- 27712400 TI - Visual and audio emotion processing training for outpatients with schizophrenia: an integrated multisensory approach. AB - Deficits in emotion processing (EP) represent a target of rehabilitation in schizophrenia, as they have been related to poor personal and social functioning. To date neither the relationship between these deficits and the generalised cognitive impairment, nor the involvement of specific mechanisms of perception (visual or auditory) are fully comprehended. We developed two treatments targeting EP, through visual or auditory channels, with the aim of disentangling possible differences and/or interactions between the two modalities in schizophrenia-related impairments, also taking into account the role of cognition and social functioning. Thirty five outpatients with schizophrenia were assessed for neurocognition, social functioning and EP (visual and auditory channel) and participated in either visual or auditory EP training or in an active control group. Results showed a significant improvement in EP through the specific channel trained for both groups, with an extended effect also on vocal stimuli for the visual training group. Positive correlations were found between working memory, social functioning and EP. Our findings help to shed light on the possible different involvement of perceptual channels in schizophrenia, as well as supporting previous evidence that emotion recognition may be inter-related but does not overlap with neurocognition and can be specifically trained. PMID- 27712404 TI - The crossover study design and its clinical application. AB - This paper describes the crossover design in research methodology and illustrates its use in a clinical study in an intensive care unit (ICU). The benefits and shortcomings of the design are described. Strategies to avoid or minimise the shortcomings are explained with reference to examples from a study carried out in clinical practice. By linking theory to practice in this way, we hope to help to increase the understanding of this methodology for the nurse researcher. PMID- 27712405 TI - Introducing single case study research design: an overview. AB - An overview of case study research The use of case study design in research has a long and distinguished history in many disciplines ( 1 ). It is used in law, education, history, medicine, psychology and business ( 2 ). Yin ( 3 ) stated that case studies are essential for social science and that they are used extensively in practice-oriented professions. Examples of studies include those of Freud, from which he derived his theories of personality ( 4 ), and Whyte's study of neighbourhood gangs in Chicago ( 5 ), which was found by other researchers ( 6 ) to be a typical case and again, as in the example of Freud, led to the development of theory. The term 'case study' refers to both a process of inquiry - that is, studying a case or designing and executing a case study - and its end product, the case study or 'case report' ( 7 ). PMID- 27712406 TI - Single case experimental design: controlling the study. AB - Single case reports are popular in nursing, as well as, for example, in education, psychology and medicine, and can give a clear picture of aspects of individual characteristics in a way that neither large scale controlled trials nor even large scale qualitative studies can hope to do. In both these latter cases, considerable individual detail is lost, owing to the need to present what is essentially a precis of these characteristics in the final published report. PMID- 27712407 TI - Linking philosophy and method in the research process: the case for realism. AB - The early stages of a research study involve much thought, reflection and planning. A clear understanding of the philosophical basis of the research strategy is important for a number of reasons. It helps to clarify research design; enables recognition of whether the strategy will or will not work; helps to identify and create designs beyond past experience ( 1 ); helps to ensure consistency in the application of different methods to a research question; and provides grounding for research methods within an accepted epistemological paradigm. This differentiates academic work from lay knowledge, by increasing its validity ( 2 ). PMID- 27712408 TI - Dilemmas of interviewing women who have given birth in Pakistan. AB - This paper focuses upon dilemmas that arose when Pakistani women were interviewed about their birth experiences in Pakistan. The dilemmas are grounded in issues from my own background and research stance and the methodology used. These factors expose issues from my white Western heritage and entry to the research field, as well as dilemmas ranging from power within the method to the sensitivity around the role and accountability of the interviewer. The over arching dilemma involves the heavy weight of responsibility incumbent upon me to interpret the women's words accurately and leave them unharmed by the experience of being interviewed. PMID- 27712409 TI - Anisotropic Shape-Memory Alginate Scaffolds Functionalized with Either Type I or Type II Collagen for Cartilage Tissue Engineering. AB - Regenerating articular cartilage and fibrocartilaginous tissue such as the meniscus is still a challenge in orthopedic medicine. While a range of different scaffolds have been developed for joint repair, none have facilitated the development of a tissue that mimics the complexity of soft tissues such as articular cartilage. Furthermore, many of these scaffolds are not designed to function in mechanically challenging joint environments. The overall goal of this study was to develop a porous, biomimetic, shape-memory alginate scaffold for directing cartilage regeneration. To this end, a scaffold was designed with architectural cues to guide cellular and neo-tissue alignment, which was additionally functionalized with a range of extracellular matrix cues to direct stem cell differentiation toward the chondrogenic lineage. Shape-memory properties were introduced by covalent cross-linking alginate using carbodiimide chemistry, while the architecture of the scaffold was modified using a directional freezing technique. Introducing such an aligned pore structure was found to improve the mechanical properties of the scaffold, and promoted higher levels of sulfated glycosaminoglycans (sGAG) and collagen deposition compared to an isotropic (nonaligned) pore geometry when seeded with adult human stem cells. Functionalization with collagen improved stem cell recruitment into the scaffold and facilitated more homogenous cartilage tissue deposition throughout the construct. Incorporating type II collagen into the scaffolds led to greater cell proliferation, higher sGAG and collagen accumulation, and the development of a stiffer tissue compared to scaffolds functionalized with type I collagen. The results of this study demonstrate how both scaffold architecture and composition can be tailored in a shape-memory alginate scaffold to direct stem cell differentiation and support the development of complex cartilaginous tissues.

PMID- 27712416 TI - A good read. AB - Actively ageing magazines are a publishing hit. Magazines specifically directed at older people, such as The Oldie, Choice, Saga and Yours, have achieved success at the national level. Actively ageing is the market with potential these days. This year, three magazines for the over-55s have appeared as part of that other publishing phenomenon, the county magazines. 'The idea is to produce a good, reader-based magazine,' says Paul Hazeldine, editor of Our Time Staffordshire. 'We want to get reaction and participation from readers, so they make the magazine part of their life.' PMID- 27712417 TI - Dynamic role boundaries in intermediate care services. AB - The rapid growth and development of intermediate care services for older people has led to wide variations in service delivery and istaffing arrangements. This paper reports an exploratory investigation which used a case study approach to examine two services run by one primary care trust. One focused on admission avoidance (Rapid Response), while the other supported discharges from institutional care (Hospital at Home). Even though both services were labelled as 'intermediate care', they were different in almost every major aspect of service organisation and delivery. Nurses and therapists working with the rapid response team felt that there was little role overlap, while the longer term nature of hospital at home provided more scope for it. The researchers conclude that role overlap can benefit all concerned. PMID- 27712422 TI - ?

This study conducted in Florida built upon an earlier one by the same authors to follow up subjects after an interval of 18 months. There were 70 women aged 65 and over in the sample. Instruments employed included the Multidimensional Health Locus of Control Scale, and the Perceived Health Competence Scale. The study revealed that the prevalence of herbal product usage and the number of products used remained the same over the 18-month period. Differences in locus of control between users and non-users were not statistically significant. PMID- 27712425 TI - New scheme offers protection to vulnerable older people.

AB - This Dutch study reports the results of using maggots to treat Gram-positive and Gramnegative infected wounds in 16 patients, half of whom had suffered trauma. The authors stress the limitations of this trial as it was an open label, non comparative cohort study in design, and all patients with a severe wound infection were treated with antibiotics. However, even though no definite conclusions regarding the effectiveness of maggot therapy could be drawn, useful pointers for clinical practice were reported. The mean treatment time was found to be 27 days, with a range of 11 to 83 days, and with the maggots being changed an average of seven times. Maggot therapy was found to be more effective in Gram positive wounds. The authors conclude by discussing what is known about the mechanisms through which maggots affect wounds.

In addition, social support, eating-related disabilities and age were found to have a significant impact. PMID- 27712429 TI - ? AB - Mixed methodologies were employed in this study of hope-fostering strategies. The sample of ten older people, drawn from Canadian rural prairie communities, was arrived at through theoretical purposive sampling. The data collection instruments employed were the Herth Hope Index and the Edmonton Symptom Assessment Scale. The interviews revealed a range of hopefostering strategies, including 'leaving a legacy', 'short term goals', 'faith', and 'symbols of hope'. As one participant said, 'These robins, they hop along, and they sing to me, they say "cheer up, cheer up".' The authors discuss their findings in the light of previous studies of hope-fostering strategies. PMID- 27712430 TI - Lessons learned from NHS leadership programme.

PMID- 27712432 TI - A chemical stability study of trimethylsilane plasma nanocoatings for coronary stents. AB - Trimethylsilane (TMS) plasma nanocoatings were deposited onto stainless steel coupons in direct current (DC) and radio frequency (RF) glow discharges and additional NH3/O2 plasma treatment to tailor the coating surface properties. The chemical stability of the nanocoatings were evaluated after 12 week storage under dry condition (25 degrees C) and immersion in simulated body fluid (SBF) at 37 degrees C. It was found that nanocoatings did not impact surface roughness of underlying stainless steel substrates. X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy were used to characterize surface chemistry and compositions. Both DC and RF nanocoatings had Si- and C-rich composition; and the O- and N-contents on the surfaces were substantially increased after NH3/O2 plasma treatment. Contact angle measurements showed that DC-TMS nanocoating with NH3/O2 treatment generated very hydrophilic surfaces. DC TMS nanocoatings with NH3/O2 treatment showed minimal surface chemistry change after 12 week immersion in SBF. However, nitrogen functionalities on RF-TMS coating with NH3/O2 post treatment were not as stable as in DC case. Cell culture studies revealed that the surfaces with DC coating and NH3/O2 post treatment demonstrated substantially improved proliferation of endothelial cells over the 12 week storage period at both dry and wet conditions, as compared to other coated surfaces. Therefore, DC nanocoatings with NH3/O2 post treatment may be chemically stable for long-term properties, including shelf-life storage and exposure to the bloodstream for coronary stent applications.

PMID- 27712455 TI - Independent Component Decomposition of Human Somatosensory Evoked Potentials Recorded by Micro-Electrocorticography. AB - High-density surface microelectrodes for electrocorticography (ECoG) have become more common in recent years for recording electrical signals from the cortex. With an acceptable invasiveness/signal fidelity trade-off and high spatial resolution, micro-ECoG is a promising tool to resolve fine task-related spatial temporal dynamics. However, volume conduction - not a negligible phenomenon - is likely to frustrate efforts to obtain reliable and resolved signals from a sub millimeter electrode array. To address this issue, we performed an independent component analysis (ICA) on micro-ECoG recordings of somatosensory-evoked potentials (SEPs) elicited by median nerve stimulation in three human patients undergoing brain surgery for tumor resection. Using well-described cortical responses in SEPs, we were able to validate our results showing that the array could segregate different functional units possessing unique, highly localized spatial distributions. The representation of signals through the root-mean-square (rms) maps and the signal-to-noise ratio (SNR) analysis emphasizes the advantages of adopting a source analysis approach on micro-ECoG recordings in order to obtain a clear picture of cortical activity. The implications are twofold: while on one side ICA may be used as a spatial-temporal filter extracting micro-signal components relevant to tasks for brain-computer interface (BCI) applications, it could also be adopted to accurately identify the sites of nonfunctional regions for clinical purposes. PMID- 27712457 TI - Do we understand pain from a biopsychosocial perspective? A review and discussion of the usefulness of some pain terms. AB - Pain is a biopsychosocial phenomenon and should be assessed and managed from this perspective. However, the dualistic mind-body perspective is still present and affects the way this health situation is addressed. Following this approach, pain can either be attributed to an identifiable cause or considered as 'psychological' pain, for which there is neither an identifiable cause nor adequate treatment. Faced with this situation, first, we introduce some concepts that have been used (and are still frequently being used) to refer to pain with no identifiable cause. Next, we question the usefulness of these 'dualistic terms' and, finally, defend the biopsychosocial perspective to advance in the conceptualization of pain and avoid using terms that can foster a dualistic perspective. PMID- 27712456 TI - Emergence of Narrowband High Frequency Oscillations from Asynchronous, Uncoupled Neural Firing. AB - Previous experimental studies have demonstrated the emergence of narrowband local field potential oscillations during epileptic seizures in which the underlying neural activity appears to be completely asynchronous. We derive a mathematical model explaining how this counterintuitive phenomenon may occur, showing that a population of independent, completely asynchronous neurons may produce narrowband oscillations if each neuron fires quasi-periodically, without requiring any intrinsic oscillatory cells or feedback inhibition. This quasi-periodicity can occur through cells with similar frequency-current ([Formula: see text]-[Formula: see text]) curves receiving a similar, high amount of uncorrelated synaptic noise. Thus, this source of oscillatory behavior is distinct from the usual cases (pacemaker cells entraining a network, or oscillations being an inherent property of the network structure), as it requires no oscillatory drive nor any specific network or cellular properties other than cells that repetitively fire with continual stimulus. We also deduce bounds on the degree of variability in neural spike-timing which will permit the emergence of such oscillations, both for action potential- and postsynaptic potential-dominated LFPs. These results suggest that even an uncoupled network may generate collective rhythms, implying that the breakdown of inhibition and high synaptic input often observed during epileptic seizures may generate narrowband oscillations. We propose that this mechanism may explain why so many disparate epileptic and normal brain mechanisms can produce similar high frequency oscillations. PMID- 27712458 TI - Acceptability of a brief computerized intervention targeting anxiety sensitivity. AB - Despite the well-documented efficacy of cognitive behavioral treatments for anxiety disorders, the acceptability of these treatments remains an under researched area. A better understanding of acceptability could help to improve the initiation of, and engagement in, these effective interventions. Recent research has suggested computerized interventions of anxiety-related risk factors may be one way to improve acceptability and overcome several common barriers to treatment. Considering this, the current study tested the acceptability of a computerized, anxiety sensitivity (AS)-focused treatment among a sample of treatment-seeking community participants and military veterans (N = 58). Results indicated that the majority of participants rated the intervention as acceptable, and that drop-out rate was low (ie 5%). Moreover, higher acceptability scores were associated with older age, veteran status, lower income levels, African American race, and being separated/divorced. Findings suggest that a computerized AS-focused treatment may be an acceptable treatment method, and may have advantages in acceptability for hard to reach populations. PMID- 27712461 TI - Oral Health-Related Quality of Life Before and After Treatment of Dentin Hypersensitivity With Cyanoacrylate and Laser. AB - BACKGROUND: The aim of this longitudinal study is to verify changes in the oral health-related quality of life of patients 180 days after treatment of dentin hypersensitivity (DH) with laser and cyanoacrylate. METHODS: This clinical, controlled, randomized, double-masked trial used a split-mouth design, and quadrants were randomized to receive either laser or cyanoacrylate treatments. All patients received both treatments. The study included 62 patients aged 12 to 60 years (mean: 31.4 years) in whom a total of 432 teeth were treated. Quadrants were randomly distributed into two groups: cyanoacrylate (n = 218 teeth) or laser (n = 216 teeth) treatment. DH was evaluated with air and cold stimuli at 24 hours, 30, 90, and 180 days after treatment. The Oral Health Impact Profile (OHIP 14) questionnaire was applied at baseline and 180 days after treatment. RESULTS: There were statistically significant differences in the following OHIP-14 subscales before and after treatment: physical pain (P = 0.002), psychologic discomfort (P <0.001), psychologic disability (P = 0.003), social disability (P = 0.01), and total score (P <0.001). At the end of the study, 80.6% of participants reported an improvement in their condition. CONCLUSION: There was a reduction in the impact of DH on the quality of life of study participants after interventions with laser and cyanoacrylate. PMID- 27712462 TI - Mandibular Degree II Furcation Defects Treatment With Platelet-Rich Fibrin and 1% Alendronate Gel Combination: A Randomized Controlled Clinical Trial. AB - BACKGROUND: Different materials have been investigated for renewal of lost supporting periodontal structures and tested for furcation defect treatment. Platelet-rich fibrin (PRF) is a pool of growth-promoting factors and cytokines that promote bone regeneration and maturation of soft tissue. Alendronate (ALN), an influential member of the bisphosphonate group, is known to enhance osteoblastogenesis and inhibit osteoclastic bone resorption, thus promoting tissue regeneration. This randomized trial was done to assess effectiveness of PRF and 1% ALN gel combination in mandibular degree II furcation defect treatment in comparison with PRF and access therapy alone. METHODS: Seventy-two mandibular molar furcation defects were treated with either access therapy alone (group 1), access therapy with PRF (group 2), or access therapy with PRF and 1% ALN (group 3). Plaque index, modified sulcus bleeding index, probing depth (PD), relative vertical attachment level (RVAL) and relative horizontal attachment level (RHAL), and intrabony defect depth were recorded at baseline and 9 months postoperatively. Radiographically, defect fill, assessed in percentage, was evaluated at baseline, before surgery, and 9 months post-therapy. RESULTS: Group 3 showed greater PD reduction and RVAL and RHAL gain when compared with groups 1 and 2 postoperatively. Moreover, group 3 sites showed a significantly greater percentage of radiographic defect fill (56.01% +/- 2.64%) when compared with group 2 (49.43% +/- 3.70%) and group 1 (10.25% +/- 3.66%) at 9 months. CONCLUSIONS: Furcation defect treatment with autologous PRF combined with 1% ALN gel results in significant therapeutic outcomes when compared with PRF and access therapy alone. Combining ALN with PRF has potential for regeneration of furcation defects without any adverse effect on healing process. PMID- 27712463 TI - Peptide 19 of Porphyromonas gingivalis Heat Shock Protein Is a Potent Inducer of Low-Density Lipoprotein Oxidation. AB - BACKGROUND: Although periodontal pathogens show a strong association with development of atherosclerosis, little is known about how a microorganism contributes to disease onset and progression. Oxidation of low-density lipoprotein (LDL) is a major risk factor of atherogenesis. The principal objective of this study is to evaluate the ability of peptide 19 (Pep19) of Porphyromonas gingivalis (Pg) heat shock protein (HSP) as a potent inducer of LDL oxidation, and a secondary objective is to compare this ability with that of Pep19 from different bacteria. METHODS: HSP60, Pep14, and Pep19 from Pg and THP-1 monocytes were cultured, and the extent of LDL oxidation induced by each peptide was evaluated by an assay for thiobarbituric acid-reactive substances (TBARS). Pep19 and HSP60 from Chlamydia pneumoniae and Mycobacterium tuberculosis were also cultured with THP-1 monocytes and evaluated by the TBARS assay. After incubation of macrophages with LDL and peptides from Pg, Oil Red O staining was performed for examination of foam cells, macrophages that took up the oxidized LDL. RESULTS: Monocyte-mediated native-LDL oxidation under the influence of Pep19 or HSP60 from Pg was significantly stronger than oxidation induced by the counterpart Pep19 or HSP60 from C. pneumoniae or M. tuberculosis. Pep19 from Pg HSP60 showed a stronger ability to induce LDL oxidation than did Pep14 from Pg HSP60. CONCLUSION: These results suggest Pep19 from Pg HSP60 has a distinct ability to induce native-LDL oxidation as a plausible mechanism by which this peptide may drive epitope spreading to the neoantigen, i.e., oxidized LDL, in the pathogenesis of atherosclerosis. PMID- 27712464 TI - In Vitro Biofilm Formation on Titanium and Zirconia Implant Surfaces. AB - BACKGROUND: It has been hypothesized that zirconia might have a reduced bacterial adhesion compared with titanium; however, results from experimental studies are rather controversial. The aim of the present study is to compare biofilm formation on zirconia and titanium implant surfaces using an in vitro three species biofilm and human plaque samples. METHODS: Experimental disks made of titanium (Ti) or zirconia (ZrO2) with a machined (M) or a sandblasted (SLA) and acid-etched (ZLA) surface topography were produced. An in vitro three-species biofilm or human plaque samples were applied for bacterial adhesion to each type of disk, which after 72 hours of incubation was assessed using an anaerobic flow chamber model. RESULTS: Zirconia showed a statistically significant reduction in three-species biofilm thickness compared with titanium (ZrO2-M: 8.41 MUm; ZrO2 ZLA: 17.47 MUm; Ti-M: 13.12 MUm; Ti-SLA: 21.97 MUm); however, no differences were found regarding three-species-biofilm mass and metabolism. Human plaque analysis showed optical density values of 0.06 and 0.08 for ZrO2-M and ZrO2-ZLA, and values of 0.1 and 0.13 for Ti-M and Ti-SLA, respectively; indicating a statistically significant reduction in human biofilm mass on zirconia compared with titanium. Additionally, zirconia revealed a statistically significant reduction in human plaque thickness (ZrO2-M: 9.04 MUm; ZrO2-ZLA: 13.83 MUm; Ti-M: 13.42 MUm; Ti-SLA: 21.3 MUm) but a similar human plaque metabolism compared with titanium. CONCLUSION: Zirconia implant surfaces showed a statistically significant reduction in human plaque biofilm formation after 72 hours of incubation in an experimental anaerobic flow chamber model compared with titanium implant surfaces. PMID- 27712465 TI - Antioxidant capacity of (+)-catechin visible-light photoirradiated in the presence of vitamin B2. AB - OBJECTIVES: Catechins are important components of human diet and have received special attention due to their antioxidant capacity. The purpose of this paper was to study the antioxidant action of (+)-catechin (CTQ) in the presence of vitamin B2 (riboflavin) as light-absorbing agent. Furthermore, two model compounds, catechol (CTC) and resorcinol (RSC), were selected in order to elucidate the reactive target of the CTQ molecule. The influence of pH-medium was investigated. METHODS: Stationary photolysis, polarographic detection of dissolved oxygen, reactive oxygen species (ROS)-scavengers, time-resolved near-IR phosphorescence detection, stationary, and time-resolved fluorescence and laser flash photolysis techniques were employed. RESULTS: CTQ interacts with riboflavin under visible-light photoirradiation as well as with different ROS which are generated in this mechanism. Radical-scavenging activity increases with increasing of pH-medium. DISCUSSION: pH-effect of the medium on radical scavenging activity comes from the increased electron-donating ability of CTQ upon deprotonation. These results are very interesting due to the fact that the pH of the food products displays important variations. The [Formula: see text] scavenging ability of CTQ, would be equal to the additive contribution of each reactive center, CTC, and RSC, present at the molecule of CTQ. However, CTQ would have a moderate ability to removal of [Formula: see text]-species at pH 7. PMID- 27712468 TI - Issues in research.

The role of traditional medicine in mental health care in Rwanda and Eastern Cape Province, South Africa. AB - Traditional medicine (TM) and biomedicine represent parallel health systems in many developing countries; the latter dominating in public policies, while the former still retain considerable influence among the general public. This study investigates how mental health care professionals responsible for mental health care implementation comprehend and relate to the intersection between TM and biomedicine in the cases of Rwanda and the Eastern Cape Province, South Africa. The material is based on semi-structured interviews with mental health care stakeholders in Eastern Cape, South Africa and Rwanda. The findings confirm an impact of TM in the treatment of mental health issues in Rwanda and South Africa due to TM being more accessible than biomedical medicine, widespread traditional perceptions of mental illness in society, and the lack of knowledge of biomedical treatments. Furthermore, the respondents identified three strategies to manage the impact of TM; improved accessibility of biomedical facilities, outreach education about mental illness, and, in the Eastern Cape case, collaboration between traditional healers and biomedicine. The study points to the necessity to take TM into consideration as an important component of health systems and policies in the Global south. PMID- 27712469 TI - Collaboration in research.

Modifiable risk factors have been identified and poor folate status is suspected of being one such risk factor. This trial compared three years of folic acid supplementation with placebo in people, aged 50-70, who had raised blood concentrations of homocysteine (associated with atherosclerosis). The findings were that folic acid supplementation significantly improved those domains of cognitive function (memory and information processing) that tend to decline with age. PMID- 27712487 TI - Cognitive impairment may not hamper ability to describe quality of life. AB - Subjective accounts of quality of life are vital if we are to better understand the experience of people with dementia; however, cognitive limitations and lack of insight have been seen as barriers to self-reporting in quality of life assessment. Nevertheless, it has been suggested that awareness of feelings may be preserved even when awareness of cognitive deficits is impaired.

Between 10 20 per cent of falls cause injury of some sort and even apparently 'minor' soft tissue injury can lead to significant loss of function in frailer people. Falls can also result in distressing 'long lie' where victims are unable to get up, and this may lead to pressure damage, dehydration or hypothermia. Falls are also frequently an indicator of underlying medical or social problems and the first 'red flag' suggesting that something is wrong. PMID- 27712493 TI - Heather Middleton. AB - The things the older people I have known value most are the company of family and friends, being seen as a person (or even just 'being seen'), and being able to maintain their independence.

AB - Multifactorial assessment and targeted intervention to reduce falls among older people has for some time been considered an effective intervention ( Gillespie et al 2003 ; Chang et al 2004 ). This practice normally involves identifying the risk status of individuals and then intervening to reduce such risks by, for example, medication review, offering professionally prescribed gait training, exercise programmes toimprove strength and balance, modification of environmental hazards and so on. It has been the cornerstone of UK NHS policy implemented by NICE ( 2004 ). PMID- 27712496 TI - Sharing funding for long term care.

AB - Anxiety and depressive disorders are often comorbid. Transdiagnostic and tailored treatments seem to be promising approaches in dealing with comorbidity. Although several primary studies have examined the effects of Internet-delivered cognitive behavior therapy (iCBT) for anxiety and depression, no meta-analysis including different types of iCBT that address comorbidity has been conducted so far. We conducted systematic searches in databases up to 1 July 2016. Only randomized trials comparing transdiagnostic/tailored iCBT for adult anxiety and/or depression with control groups were included. Nineteen randomized trials with a total of 2952 participants that met inclusion criteria were analyzed. The quality of the studies was high, however the blinding criteria were not fulfilled. The uncontrolled effect size (Hedges' g) of transdiagnostic/tailored iCBT on anxiety and depression outcomes was large and medium for quality of life. The controlled effect size for iCBT on anxiety and depression outcomes was medium to large (anxiety: g = .82, 95% CI: .58-1.05, depression: g = .79, 95% CI: .59-1.00) and medium on quality of life (g = .56, 95% CI: .37-.73). Heterogeneity was small (quality of life) to moderate (anxiety, depression). There was a large effect on generic outcome measures and a moderate effect on comorbidities. When compared to disorder-specific treatments there were no differences on anxiety and quality of life outcomes, however there were differences in depression outcomes. Transdiagnostic and tailored iCBT are effective interventions for anxiety disorders and depression. Future studies should investigate mechanisms of change and develop outcome measures for these interventions. PMID- 27712545 TI - How does the small picture relate to the bigger picture?

This study explores the decisions therapists make regarding self-disclosure, which impacts the psychotherapy process. METHOD: This grounded theory study explores psychotherapists' S/R/N self-disclosure based on qualitative interviews with 21 psychotherapists representing varied theoretical orientations and spiritual, religious, atheist, and agnostic backgrounds. RESULTS: Findings reveal that while some self-disclosure happens on an explicit level, more often psychotherapists find implicit ways to share S/R/N aspects of the self for purposes of enhancing the therapeutic alliance and to convey openness. Psychotherapists also attempt to avoid the topic altogether, either to protect the therapeutic relationship or because of unresolved S/R/N identity in the therapist. CONCLUSIONS: Developing skills related to S/R/N self-disclosure represents an important aspect of multicultural competence, which can impact clients' feelings of safety and comfort discussing their own S/R/N identity. This capacity is strongly influenced by the therapist's self-awareness regarding S/R/N identity. Suggestions for engaging S/R/N identity and disclosure in supervisory experiences and academic preparation are discussed. PMID- 27712550 TI - Delinquency, Drug Abuse and Alcoholism.

AB - This paper introduces the special issue focused on the relationship between residence and health in Australia. We present six papers conducted in different Australian states that demonstrate different elements of the complex impact of residential context on health. Through this series of papers, we demonstrate the impact of housing quality and safety on vulnerable populations, but also the way in which processes around housing (e.g., data collection, renewal, allocation) can have either negative or positive outcomes. The broader residential context (i.e., neighborhood, community, geographic location) also must be considered in housing decisions, along with variables that closely track housing (e.g., stigma, poverty). Australia is in the middle of a housing crisis that can still be resolved in positive ways if adequate attention is given to the nuances and complexities of housing decisions. PMID- 27712553 TI - A place to call my own: Young people with complex disabilities living in long term care. AB - It is important to consider the nature of home in more detail when thinking about living environments for vulnerable groups of people, especially as it has been found that the nature of home can impact on the quality of life. The aim of this study was to understand the "lived experience" of home for a group of young people with complex disabilities who had recently relocated to a specially designed residential apartment building. Multiple domains of home, as they were experienced over time, were examined through a series of semi-structured interviews conducted with seven residents at their apartments. The findings revealed two major themes ("perceived quality of the place" and "identity in place") that were inextricably interlinked. To the extent that they overlapped, the experience of home was enhanced. The interaction between the two themes was associated with a dynamic ongoing process whereby the sense of home was either created or damaged ("deconstruction and reconstruction of home"). The current study has implications for how residential care workers are trained and supported if the well-being of individuals with complex disabilities is to be promoted within residential settings. PMID- 27712554 TI - Where you live and who you live with matters: Housing and mental health. AB - This article considers the relationship between where a person lives and who they live with and their mental health and well-being. In particular, this article considers the regional locale as an important factor in understanding the perspective of a person with lived experience of mental illness. This article questions the influential, yet somewhat narrow, argument that living in the community and in the family home is somehow better for people with mental illness. The arguments presented in this article illustrate that for some people with mental illness, the issues of stigma, autonomy, and lack of alternatives (choice) are just as prevalent for them now, living in the community, as when they lived in institutions. The assumption that place alone can redress the lack of choice and autonomy is unfounded. PMID- 27712555 TI - The cunning of data in Indigenous housing and health. AB - This article explores why it is so difficult to provide and sustain decent public housing in Indigenous communities, highlighting the curious role that data reporting and analysis plays in perpetuating this state of affairs. Drawing on data amassed by the Housing for Health (HFH) program that has focused on "health hardware" functionality in almost 9,000 houses in over 215 communities across Australia, we note inroads made to the language of policy (through, for example, the development of a National Indigenous Housing Guide). However, we also note the more limited effect on those policy practices that ordain substandard housing function. There is an intimate relationship between this outcome and the paradoxical state of the Indigenous housing and health evidence base, a field which is simultaneously awash with multiple databases providing synoptic information at regional, state/territory, and national levels, yet lacking specificity in relation to the health-enabling status of housing infrastructure. PMID- 27712556 TI - Public housing renewal and social determinants of health. AB - This article draws on the concept of residential context of housing and its relationship to health. It considers a bundle of changes through implementation of a housing renewal initiative as part of the Carlton Housing Estate Upgrading Project in Melbourne, Australia. Beyond the quality and appropriateness of the housing, pertinent factors explored include social networks, safety and security, and green open space. Data collection for the research project included in-depth interviews with public housing tenants, private residents, and service providers who live on and service the estate, as well as neighborhood observations and participation in on-site events. A key finding was that the relational processes of how tenants were related to by others-specifically, the way housing was reallocated during the processes of renewal-affected social housing tenants' self perceived health and well-being. PMID- 27712557 TI - Poor housing quality: Prevalence and health effects. AB - Housing is a central component of productive, healthy, and meaningful lives, and a principle social determinant of health and well-being. Surprisingly, though, evidence on the ways that housing influences health in Australia is poorly developed. This stems largely from the fact that the majority of the population are accommodated in good quality housing. The dominance of a "good housing paradigm" means that households living in poor quality and unhealthy housing are doubly disadvantaged-by the quality of their housing and because policy makers in Australia do not acknowledge the health effects of housing. In this article, we examine the relationship between health outcomes and quality of housing. We base our analysis on data from the Household Income and Labour Dynamics in Australia (HILDA) survey, a panel dataset that is representative across Australia. We find a sizeable, policy-important, and to date under-acknowledged cohort of Australians whose health is influenced by poor-condition dwellings. PMID- 27712558 TI - Self-assessed health status and neighborhood context. AB - In recent years, there has been growing interest in the relationship between the characteristics of neighborhoods and the health and well-being of residents. The focus on neighborhood as a health determinant is based on the hypothesis that residing in a disadvantaged neighborhood can negatively influence health outcomes beyond the effect of individual characteristics. In this article, we examine three possible ways of measuring neighborhood socio-economic status, and how they each impact on self-reported health status beyond the effect contributed by individual-level factors. Using individual-level data from the Household Income and Labor Dynamics Australia survey combined with neighborhood-level (suburb) data, we tested the proposition that how one measures neighborhood socio-economic characteristics may provide an important new insight into understanding the links between individual-level outcomes and neighborhood-level characteristics. The findings from the analysis illustrate that although individual-level factors may be important to understanding health outcomes, how one accounts for neighborhood level socio-economic status may be equally important. The findings suggest that in developing place-based health programs, policy makers need to account for the complex interactions between individual drivers and the potential complexities of accounting for neighborhood socio-economic status.

AB - BACKGROUND: In Chinese folk medicine, Corni fructus (C. fructus) has traditionally been used to improve liver function, although the mechanism underlying its activity remains unclear. The aim of the present study was to evaluate the protective effects of wild C. fructus methanolic extract against acute alcoholic liver injury. METHODS: Alcohol was administered to mice for three consecutive days, either alone or in combination with C. fructus methanolic extract (50, 100, or 200 mg/kg body weight/d). Serum and liver tissue were collected from the animals and subjected to biochemical and histopathological analyses. RESULTS: C. fructus significantly alleviated alcohol-induced liver injury by reducing serum alanine aminotransferase, aspartate aminotransferase, and thiobarbituric acid reactive species, inhibiting hydroxyl radicals (*OH), and increasing total superoxide dismutase, glutathione peroxidase, and glutathione in the liver (P < 0.05). In addition, the C. fructus treatment inhibited the expression and activity of cytochrome P450 2E1 (P < 0.05). CONCLUSIONS: C. fructus could be a promising natural substance for ameliorating acute alcohol induced oxidative stress and hepatic injury.

PMID- 27712567 TI - Development and Optimization of Controlled Porosity Osmotic Tablets of Lamotrigine Solid Dispersion. AB - BACKGROUND: The purpose of this study was to investigate the application of a controlled porosity osmotic tablet (CPOT) utilizing solid dispersion (SD) of poorly soluble drug. The patents on Cyclobenzaprine HCl (US4968507 A) and Venlafaxine salts (EP 2085078 A1) helped in the selection of drug and polymers. METHOD: The SDs having different ratio of drug to carrier (PVP K 30) were prepared by kneading method and optimized. Effect of three independent variables, total amount of osmogen (mannitol& potassium chloride), total amount of polymer (polyethylene oxide WSR 301, hydroxy propyl methyl cellulose K100 M) and polymer1: polymer 2 ratio were investigated using Box Behnken design. Core and coated tablets were evaluated for various parameters. In-vitro drug release profiles of CPOT tablets were compared with reference product Diffcore tablet, Lamictal XR (GlaxoSmith Kline Inc., USA). RESULTS: All formulations showed acceptable parameters. Drug release from CPOT was determined as complete, zero order and pH-independent within the physiological pH range of the GI tract. Drug release was directly proportional to initial level of polymers and osmogens. CONCLUSION: The present results confirmed that prepared LTG SD serves as solubility modulator. Further, CPOT of LTG based on SD proved to be successful in delivering the drug in a controlled manner ensuring the once daily dosing for the treatment of convulsive disorders. PMID- 27712568 TI - Formulation Development and Optimization of Matrix Tablet of Tramadol Hydrochloride. AB - BACKGROUND: The aim of the present investigation is to formulate and optimize oral sustained release matrix tablet of highly water soluble drug Tramadol HCl and to evaluate the effect of varying concentration of hydrophilic and hydrophobic polymer on drug release, based on a survey done on the recent patents of Tramadol HCl (US7374781, CA 2479252) and sustained release matrix tablets. METHODS: The tablets were prepared by double granulation process, by melt granulation and wet granulation technique using Carnauba wax (CW) and HPMC K100 as release retardant. RESULTS: Pre and post compression factors were evaluated and all the parameters were found within the limit. The drug release data were subjected to different models in order to evaluate release kinetics and mechanism of drug release. The prepared formulations showed drug release in the range 100+/ 2% in 6hrs, 7hrs, 8hrs and 9hrs and upto 12 hrs respectively. The optimized tablet having 25% CW and 20% HPMC showed sustained drug release pattern. Hydrophilic matrix of HPMC alone could not control the Tramadol release effectively for 12 h whereas when combined with CW could slow down the release of drug and can be successfully employed for formulating sustained-release matrix tablets. Similarity factor, f2 shows the test and reference profile are identical. CONCLUSION: Double granulation technique with CW and HPMC K100 proved as a better technique for sustaining the drug release from the matrix tablet.

AB - BACKGROUND: In this review article, authors reviewed about the liposomes which are amongst various drug delivering systems for the delivery of the therapeutic agents at the target site. METHODS: Advances in liposomal drug delivery systems for the cancer therapy have enhanced the therapeutic levels of the anticancer moieties. Liposomes show promising action on the tumor by incorporating less amount of drug at the target site, with minimum toxic effect and maximum therapeutic effect and thereby enhancing the bioavailability. RESULTS: Liposome based drug delivery systems provide the potential to elevate the effect of drug concentration in tumor cells.

PMID- 27712572 TI - Old, New and Hidden Causes of Perioperative Hypersensitivity. AB - Perioperative hypersensitivity reactions are rare, often life-threatening events, and subsequent investigations to identify the culprit are important to avoid re exposure. All exposures in the perioperative setting may potentially be the cause of a hypersensitivity reaction, but drugs administered intravenously such as neuromuscular blocking agents (NMBA), induction agents and antibiotics have traditionally been reported to be implicated most commonly. It has recently become apparent that there are geographical differences in sensitization patterns related to variation in exposures, referral patterns and performance and interpretation of investigations. Differences in sensitization to NMBAs are partly explained by cross sensitization to pholcodine, an ingredient in cough medicines available in some countries. While NMBAs are the most common causes of perioperative hypersensitivity in some countries, this may not necessarily be the case in all countries. New and hidden allergens have emerged as causes of perioperative hypersensitivity such as blue dyes, chlorhexidine and excipients. Detailed knowledge of the events at the time of reaction is necessary to identify potential culprits including rare and hidden allergens. Cooperation between allergists and anaesthetists, or other staff present perioperatively, is often needed to identify hidden or even undocumented exposures. The objectives of this review are to provide an overview of the history of investigation of perioperative hypersensitivity, to describe the differences in causes of perioperative hypersensitivity emerging over time and to increase awareness about the "hidden allergens" in the perioperative setting. Some practical advice on how to approach the patient testing negative on all initial investigations is also included. PMID- 27712573 TI - Diagnosing beta-Lactam Hypersensitivity. AB - Hypersensitivity reactions to beta-lactam antibiotics are commonly reported. They can be classified as immediate or non-immediate according to the time interval between the last drug administration and their onset. Immediate reactions occur within one hour after the last drug administration and are manifested clinically by urticaria and/or angioedema, rhinitis, bronchospasm, and anaphylactic shock; they may be mediated by specific IgEantibodies. Non-immediate reactions occur more than one hour after the last drug administration. The most common manifestations are maculopapular exanthemas; specific T lymphocytes may be involved in this type of manifestation. In the diagnostic evaluation of hypersensitivity reactions to beta -lactam antibiotics, the patient's history is fundamental. The allergy examination is based on in vitro and in vivo tests selected on the basis of the clinical features and the type of reaction, immediate or non-immediate. Immediate reactions can be assessed in vitro by serum specific IgE assays and basophil activation tests and in vivo by immediate reading skin tests and, in selected cases, drug provocation tests (DPTs). Non immediate reactions can be evaluated mainly by delayed-reading skin tests, patch tests, and DPTs. PMID- 27712574 TI - Progress in Polysaccharide Derivatization and Properties. AB - Polysaccharides and their derivatives have opened up new industrial field because of their special biochemical functions. Their biological immune, biological inhibition, antioxidant and anticoagulant properties have begun to help people enhance their physique, the fight against aging. Molecular modification is an important way to study the structure-activity relationship of polysaccharides which should be focused on. After molecular modification, various derivatives of different types of structures and biological activities are gained. Chemical modification of polysaccharides, e.g., carboxymethylation, sulfonylation, phosphorylation, acetylation, and hydroxypropylation, cationic or other derivatives, can improve their bioavailability and applications in different biological systems. PMID- 27712575 TI - Selective Serotonin Reuptake Inhibitors and Serotonin and Noradrenaline Reuptake Inhibitors Improve Cognitive Function in Partial Responders Depressed Patients: Results from a Prospective Observational Cohort Study. AB - BACKGROUND: Major Depressive disorder (MDD) is often accompanied by cognitive deficits, involving attention, learning, memory and executive functioning. Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin and Noradrenaline Reuptake Inhibitors (SNRIs) show efficacy on affective symptoms, but it is unclear whether or not they improve cognitive symptoms. METHODS: We carried out a 12 week-prospective observational study in two cohorts of recurrent moderate severe partial responder MDD patients, to test the hypothesis that SSRIs and/or SNRIs may affect cognitive symptoms and assess whether or not such an effect was correlated to their effect on affective symptoms. All patients underwent cognitive and neuropsychiatric assessment at baseline, 4- and 12-week follow-up. Thirty-three patients in the SSRI- and sixteen patients in the SNRI-cohort completed the follow-up. RESULTS: Both SSRIs and SNRIs reduced affective symptoms and improved global cognitive function. Both SSRIs and SNRIs improved executive function and verbal memory. Global cognitive function, verbal memory and executive function improved both in full and partial responder patients. Finally, there was no correlation between baseline Mini Mental State Examination, Montreal Cognitive Assessment and Frontal Assessment Battery scores and the mean change in Hamilton Psychiatric Rating scale for Depression or Beck Depression Inventory at the end of the 12 weeks of treatment. CONCLUSION: Present data show that SSRIs and SNRIs improve cognitive symptoms in MDD independently from their efficacy on affective symptoms. Affective and cognitive symptoms may represent distinct psychopathological dimensions of MDD with different response to antidepressant drugs. PMID- 27712576 TI - Multiple Targets for the Management of Alzheimer's Disease. AB - AD is a progressive and irreversible neurodegenerative disease and the most common cause of dementia in the elderly population. Betaeta- amyloid cascade formation along with several cytoskeleton abnormalities succeeding to the hyperphosphorylation of microtubule-associated tau protein in neurons leads to the elicitation of several neurotoxic incidents. As an outcome of these phenomena, steady growth of dementia in aged population is becoming ubiquitous in both developed and developing countries. Thus, the key aspiration is to endow with stable daily life functionality to the person suffering from dementia and to cut down or slower the symptoms of disease leading to disruptive behavior. In sight of this, the proteins amyloid-beta, BACE-1, RAGE and AChE are being aimed for the treatment of AD successfully. Currently, there are several medicines for the treatment of AD under survey like Galangin, Cymserine, Tolserine, Bisnorcymserine and Huperzine A. The article emphasizes clinical and neurobiological aspects of AD. The purpose of this review article is to provide a brief introduction of AD along with the related concept of beta-secretase, beta amyloid and neurotransmitter in the progression of disease. In the present review, we summarize the available evidence on the new therapeutic approaches that target amyloid and neurotransmitter in the AD.

PMID- 27712580 TI - PCR amplification of GC-rich DNA regions using the nucleotide analog N4-methyl-2' deoxycytidine 5'-triphosphate. AB - GC-rich DNA regions were PCR-amplified with Taq DNA polymerase using either the canonical set of deoxynucleoside triphosphates or mixtures in which the dCTP had been partially or completely replaced by its N4-methylated analog, N4-methyl-2' deoxycytidine 5'-triphosphate (N4me-dCTP). In the case of a particularly GC-rich region (78.9% GC), the PCR mixtures containing N4me-dCTP produced the expected amplicon in high yield, while mixtures containing the canonical set of nucleotides produced numerous alternative amplicons. For another GC-rich DNA region (80.6% GC), the target amplicon was only generated by re-amplifying a gel purified sample of the original amplicon with N4me-dCTP-containing PCR mixtures. In a direct PCR comparison on a highly GC-rich template, mixtures containing N4me dCTP clearly performed better than did solutions containing the canonical set of nucleotides mixed with various organic additives (DMSO, betaine, or ethylene glycol) that have been reported to resolve or alleviate problems caused by secondary structures in the DNA. This nucleotide analog was also tested in PCR amplification of DNA regions with intermediate GC content, producing the expected amplicon in each case with a melting temperature (Tm) clearly below the Tm of the same amplicon synthesized exclusively with the canonical bases. PMID- 27712581 TI - Optimization of Diamond Nucleic Acid Dye for quantitative PCR. AB - Here, we evaluate Diamond Nucleic Acid Dye (DD) for use in quantitative PCR (qPCR) applications. Although DD is a commercially available stain for detection of DNA separated by gel electrophoresis, its use as a detection dye in qPCR has yet to be described. To determine if DD can be used in qPCR, we investigated its inhibitory effects on qPCR at concentrations ranging 0.1-2.5*. Serial dilution of DNA was used to determine the efficiency, sensitivity, and linearity of DD generated qPCR data in comparison to other commonly used fluorescent dyes such as SYBR Green (SG), EvaGreen (EG), and BRYT Green (BG). DD was found to be comparable with other dyes for qPCR applications, with an R2 value >0.9 and an efficiency of 0.83. Mitochondrial DNA (mtDNA) target signals were successfully produced by DD over a DNA dilution range of ~28 ng- 0.28 pg, demonstrating comparable sensitivity to the other dyes investigated. Cq values obtained using DD were lower than those using EG by almost 7 cycles. We conclude that Diamond Nucleic Acid Dye is a cheaper, less toxic alternative for qPCR applications.

AB - Microbial colony growth can serve as a useful readout in assays for studying complex genetic interactions or the effects of chemical compounds. Although computational tools for acquiring quantitative measurements of microbial colonies have been developed, their utility can be compromised by inflexible input image requirements, non-trivial installation procedures, or complicated operation. Here, we present the Spotsizer software tool for automated colony size measurements in images of robotically arrayed microbial colonies. Spotsizer features a convenient graphical user interface (GUI), has both single-image and batch-processing capabilities, and works with multiple input image formats and different colony grid types. We demonstrate how Spotsizer can be used for high throughput quantitative analysis of fission yeast growth. The user-friendly Spotsizer tool provides rapid, accurate, and robust quantitative analyses of microbial growth in a high-throughput format. Spotsizer is freely available at https://data.csiro.au/dap/landingpage?pid=csiro:15330 under a proprietary CSIRO license. PMID- 27712583 TI - Extraction of high-molecular-weight genomic DNA for long-read sequencing of single molecules. AB - De novo sequencing of complex genomes is one of the main challenges for researchers seeking high-quality reference sequences. Many de novo assemblies are based on short reads, producing fragmented genome sequences. Third-generation sequencing, with read lengths >10 kb, will improve the assembly of complex genomes, but these techniques require high-molecular-weight genomic DNA (gDNA), and gDNA extraction protocols used for obtaining smaller fragments for short-read sequencing are not suitable for this purpose. Methods of preparing gDNA for bacterial artificial chromosome (BAC) libraries could be adapted, but these approaches are time-consuming, and commercial kits for these methods are expensive. Here, we present a protocol for rapid, inexpensive extraction of high molecular-weight gDNA from bacteria, plants, and animals. Our technique was validated using sunflower leaf samples, producing a mean read length of 12.6 kb and a maximum read length of 80 kb. PMID- 27712584 TI - A cost-effective method to immobilize hydrated soft-tissue samples for atomic force microscopy. AB - Immobilizing hydrated soft tissue specimens for atomic force microscopy (AFM) is a challenge. Here, we describe a simple and very cost-effective immobilization method, based on the use of transglutaminase in an aqueous environment, and successfully apply it to AFM characterization of human native Wharton's Jelly (nWJ), the gelatinous connective tissue matrix of the umbilical cord. A side-by side comparison with a widely used polyphenolic protein-based tissue adhesive (Corning Cell-Tak), which is known to bind strongly to virtually all inorganic and organic surfaces in aqueous environments, shows that both adhesives successfully immobilize nWJ in its physological hydrated state. The cost of transglutaminase, however, is over 3000-fold lower than that of Cell-Tak, making it a very attractive method for immobilizing soft tissues for AFM characterization. PMID- 27712585 TI - Knockdown of Rap1b Enhances Apoptosis and Autophagy in Gastric Cancer Cells via the PI3K/Akt/mTOR Pathway. AB - Gastric cancer (GC) is the fourth most common malignancy and the second leading cause of cancer mortality around the world. However, the regulatory mechanisms of GC tumorigenesis and cancer cell motility are completely unknown. We investigated the role of a RAS-related protein (Rap1b) in the progression of GC. Our results showed that the expression of Rap1b is aberrantly upregulated in GC tissue samples and human GC cell lines, and the high expression of Rap1b indicated a positive correlation with poor prognosis in patients with GC. Inhibition of endogenous Rap1b dramatically reduced the cell cycle progression but strongly enhanced the apoptosis capacity of human GC cell lines MKN-28 and SGC-7901 cells compared with the control group. Western blotting assay showed that Rap1b inhibition resulted in a significant increase in the ratio of LC3-II to LC3-I, and the levels of p62 protein were decreased in both MKN-28 and SGC-7901 cells. Furthermore, PI3K/Akt/mTOR activation was found to be maintained in a low level in the normal gastric mucosal epithelial cells, while it was significantly upregulated in GC cells, which could be decreased by Rap1b inhibition. The PI3K inhibitor LY294002 was enhanced but activator insulin-like growth factor 1 (IGF 1) blocked the Rap1b silencing-induced enhancement of apoptosis and autophagy in MKN-28 and SGC-7901 cells. In conclusion, we demonstrate that Rap1b expression is aberrantly increased in GC, resulting in the inhibition of autophagy and apoptosis of GC cells by the PI3K/Akt/mTOR pathway. This might provide a new understanding and represent a novel therapeutic target for human GC. PMID- 27712586 TI - Anexelekto (AXL) Increases Resistance to EGFR-TKI and Activation of AKT and ERK1/2 in Non-Small Cell Lung Cancer Cells. AB - Recently, epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have revolutionized non-small cell lung cancer (NSCLC) treatment. However, resistance remains a major obstacle. Anexelekto (AXL) is a member of receptor tyrosine kinases (RTKs) and shares the same downstream signaling pathways with EGFR, such as PI3K/AKT and MAPK/ERK. AXL overexpression in resistant tumors has been implicated in many previous studies in vitro and in vivo. In this study, we further examined whether expression of AXL and its downstream targets increased in gefitinib-resistant PC9 cells (PC9GR). In addition, we hypothesize that knocking down AXL in PC9GR and overexpressing AXL in PC9 using genetic tools can restore and decrease the sensitivity to gefitinib, respectively. We found that silencing AXL could sensitize the resistance to gefitinib, and the downstream pathways were significantly inhibited. Interestingly, we also discovered that increased AXL expression did promote the resistance, and its downstream targets were activated accordingly. Then 69 NSCLC patients who harbored EGFR mutation were recruited to analyze the expression of AXL and the association between AXL expression and clinical characteristics. We found that 5 of the 69 patients were AXL positive (about 7%), and AXL was related to tumor differentiation and tumor size. In this study, we concluded that the molecular mechanisms of AXL mediated resistance involved in the increased activity of the PI3K/AKT and MAPK/ERK1/2 pathways, and AXL overexpression could promote resistance, but it can be weakened when AXL expression is silenced. PMID- 27712587 TI - TIPE2 Overexpression Suppresses the Proliferation, Migration, and Invasion in Prostate Cancer Cells by Inhibiting PI3K/Akt Signaling Pathway. AB - Tumor necrosis factor-alpha (TNF-alpha)-induced protein 8-like 2 (TNFAIP8L2, TIPE2) is involved in the invasion and metastasis of human tumors. However, the functional role of TIPE2 in prostate cancer remains unclear. In the present study, we explored the role of TIPE2 in prostate cancer and cancer progression including the molecular mechanism that drives TIPE2-mediated oncogenesis. Our results showed that TIPE2 was lowly expressed in human prostate cancer tissues and cell lines. In addition, restored TIPE2 obviously inhibits proliferation in prostate cancer cells. TIPE2 overexpression also suppresses the epithelial mesenchymal transition (EMT) process and migration/invasion in prostate cancer cells. Mechanistically, TIPE2 overexpression obviously inhibits the phosphorylation levels of phosphatidylinositol 3-kinase (PI3K) and Akt in prostate cancer cells. In conclusion, for the first time we demonstrated that TIPE2 overexpression may suppress proliferation, migration, and invasion in prostate cancer cells by inhibiting the PI3K/Akt signaling pathway. Therefore, TIPE2 might serve as a potential therapeutic target for human prostate cancer. PMID- 27712588 TI - Knockdown of REV7 Inhibits Breast Cancer Cell Migration and Invasion. AB - REV7 (also known as MAD2L2) is a multifunctional protein involved in DNA damage tolerance, cell cycle regulation, gene expression, and carcinogenesis. Although its expression is reportedly associated with poor prognosis in several kinds of human cancers, the significance of REV7 expression in breast malignancies is unclear. In this study, REV7 was found to be increased in breast cancer. We found that knockdown of REV7 inhibited the migration, invasion, and epithelial mesenchymal transition (EMT) of breast cancer cells. Meanwhile, overexpression of REV7 promoted the migration, invasion, and EMT of breast cancer cells. As shown by Western blot, knockdown of REV7 can promote TGF-beta1 expression. Western blot analysis indicated that TGF-beta1 may play a role as a downstream factor of REV7. Moreover, interference of TGF-beta1 can also inhibit the cell's ability for migration, invasion, and EMT, as well as in a cell line whose REV7 is overexpressed. Taken together, these results contributed to a recognition of the oncogene functions of REV7 in breast cancer cells and provided a novel direction to treat breast cancer. PMID- 27712589 TI - Ritonavir Interacts With Belinostat to Cause Endoplasmic Reticulum Stress and Histone Acetylation in Renal Cancer Cells. AB - The histone deacetylase (HDAC) inhibitor belinostat increases the amount of unfolded proteins in cells by promoting the acetylation of heat shock protein 90 (HSP90), thereby disrupting its chaperone function. The human immunodeficiency virus protease inhibitor ritonavir, on the other hand, not only increases unfolded proteins by suppressing HSP90 but also acts as a proteasome inhibitor. We thought that belinostat and ritonavir together would induce endoplasmic reticulum (ER) stress and kill renal cancer cells effectively. The combination of belinostat and ritonavir induced drastic apoptosis and inhibited the growth of renal cancer cells synergistically. Mechanistically, the combination caused ER stress (evidenced by the increased expression of the ER stress markers) and also enhanced histone acetylation by decreasing the expression of HDACs. To our knowledge, this is the first study that showed a beneficial combined effect of belinostat and ritonavir in renal cancer cells, providing a framework for testing the combination in renal cancer patients. PMID- 27712590 TI - Knockdown of Long Noncoding RNA uc.338 by siRNA Inhibits Cellular Migration and Invasion in Human Lung Cancer Cells. AB - Lung cancer remains a critical health concern worldwide. Long noncoding RNAs with ultraconserved elements have recently been implicated in human tumorigenesis. The present study investigated the role of ultraconserved element 338 (uc.338) in the regulation of cell proliferation and metastasis in human lung cancer. Our data showed that the expression of uc.338 in lung cancer was remarkably increased in vivo and in vitro. Depletion of uc.338 with specific siRNA interference retarded the cell proliferative rate in lung cancer cell lines NCI-H929 and H1688. Furthermore, knockdown of uc.338 caused cell cycle arrest in the G0/G1 phase in both cell lines. Transwell assays showed that inhibition of uc.338 notably decreased migration and invasion in NCI-H929 and H1688 cells. Moreover, uc.338 depletion decreased the expression of cyclin B1, Cdc25C, Snail, vimentin, and N cadherin while increasing the protein level of E-cadherin, shown with Western blot analysis. These results suggested the pro-oncogenic potential of uc.338 in lung cancer, which might provide novel clues for the diagnosis and treatment of lung cancer in the clinic. PMID- 27712591 TI - MicroRNA-16-1 Inhibits Tumor Cell Proliferation and Induces Apoptosis in A549 Non Small Cell Lung Carcinoma Cells. AB - Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. Plenty of microRNAs (miRs), except miR-16-1, have been reported to be associated with the initiation and progression of NSCLC. This study was aimed to explore the impacts of miR-16-1 on NSCLC cells. Human NSCLC cell line A549 was used, and the expression of miR-16-1 was up- or downregulated by transfecting with miR-16-1 mimics or inhibitors. Afterward, cell proliferation and apoptosis were detected using MTT assay, BrdU assay, and Annexin V/FITC Apoptosis Detection Kit. The expression changes of proliferation- and apoptosis-related factors were measured by Western blot. Results showed that miR-16-1 overexpression significantly inhibited cell proliferation and induced apoptosis when compared with the control group. Besides, miR-16-1 overexpression significantly upregulated the protein expressions of p27, Bax, procaspase 3, and cleaved caspase 3, whereas it downregulated Bcl-2. Conversely, miR-16-1 suppression affected NSCLC cell proliferation and apoptosis, and these protein expressions resulted in completely opposite impacts. In conclusion, miR-16-1 overexpression could inhibit cell proliferation and induce apoptosis via regulating the expression of p27, Bcl-2, Bax, and caspase 3 in NSCLC cells. PMID- 27712592 TI - Suppressive Role of MicroRNA-148a in Cell Proliferation and Invasion in Ovarian Cancer Through Targeting Transforming Growth Factor-beta-Induced 2. AB - Ovarian cancer (OC) is one of the most common gynecological malignancies. MicroRNAs (miRs) play a crucial role in the development and progression of OC, but the underlying mechanism remains largely unclear. Our study investigated the regulatory role of miR-148a in OC cell proliferation and invasion. We found that miR-148a was significantly downregulated in OC tissues compared to their matched adjacent nontumor tissues. In addition, its expression was also reduced in OC cell lines (SKOV3, ES-2, OVCAR, and A2780) compared to normal ovarian epithelial cells. Overexpression of miR-148a caused a significant decrease in OC cell proliferation and invasion, as well as reduced MMP9 protein levels. Transforming growth factor-beta-induced 2 (TGFI2) was further identified as a target gene of miR-148a, and its protein expression was downregulated in OC cells after miR-148a overexpression. Restoration of TGFI2 attenuated the suppressive effects of miR 148a on OC cell proliferation and invasion. Moreover, we found that TGFI2 was remarkably upregulated in OC tissues when compared with their matched adjacent nontumor tissues, and observed a reverse correlation between miR-148a and TGFI2 expression in OC tissues. On the basis of these findings, we suggest that miR 148a inhibits OC cell proliferation and invasion partly through inhibition of TGFI2. Therefore, our study highlights the importance of the miR-148a/TGFI2 axis in the malignant progression of OC. PMID- 27712593 TI - Knockdown of UBE2T Inhibits Osteosarcoma Cell Proliferation, Migration, and Invasion by Suppressing the PI3K/Akt Signaling Pathway. AB - Ubiquitin-conjugating enzyme E2T (UBE2T), a member of the E2 family, was found to be overexpressed in a great many cancers such as bladder cancer, lung cancer, and prostate cancer. However, there have been no reports on the role of UBE2T in osteosarcoma. In this study, we tried to make the effects of UBE2T on osteosarcoma clear. The study results showed that UBE2T was overexpressed in osteosarcoma tissues and cell lines. Moreover, UBE2T knockdown inhibited osteosarcoma cell proliferation, migration, and invasion. We also observed that UBE2T downregulation could suppress the activity of the PI3K/Akt signaling pathway. Therefore, we concluded that UBE2T exerted its inhibitory effects on osteosarcoma cells via suppressing the PI3K/Akt signaling pathway. These findings indicated that UBE2T may be a potential therapeutic target for osteosarcoma treatment. PMID- 27712594 TI - MicroRNA-21 Regulates the Proliferation, Differentiation, and Apoptosis of Human Renal Cell Carcinoma Cells by the mTOR-STAT3 Signaling Pathway. AB - MicroRNA-21 (miRNA-21), a kind of short, noncoding RNAs, functioned as a tumor marker and was upregulated in renal cell carcinoma (RCC). However, the underlying mechanisms of miRNA-21 in RCC were uncertain. Therefore, the effects and mechanisms of miRNA-21 on the proliferation, differentiation, and apoptosis of cultured human RCC cells were further investigated in this study. After slicing miRNA-21 in RCC cells, the viability, mRNA expression of C/EBPalpha and PPARgamma, caspase 3 activity, and protein expression of mTOR, STAT3, and pSTAT3 were determined. It was found that knockdown of miRNA-21 downregulated the optical density (OD) value of cells, inhibited mRNA expression of PPARgamma and C/EBPalpha, and enhanced activity of caspase 3. Furthermore, protein expression of pSTAT3 was also decreased in the absence of miRNA-21. Notably, miRNA-21 changed proliferation, differentiation, and apoptosis of human RCC cells were partially regulated following the block of the mTOR-STAT3 signaling pathway by the mTOR inhibitor (XL388). It was indicated that miRNA-21 promoted proliferation and differentiation and decreased apoptosis of human RCC cells through the activation of the mTOR-STAT3 signaling pathway. PMID- 27712595 TI - Armadillo Repeat-Containing Protein 8 (ARMC8) Silencing Inhibits Proliferation and Invasion in Osteosarcoma Cells. AB - Armadillo repeat-containing protein 8 (ARMC8) plays an important role in regulating cell migration, proliferation, tissue maintenance, signal transduction, and tumorigenesis. However, the expression pattern and role of ARMC8 in osteosarcoma are still unclear. In this study, our aims were to examine the effects of ARMC8 on osteosarcoma and to explore its underlying mechanism. Our results demonstrated that ARMC8 was overexpressed in osteosarcoma cell lines. Knockdown of ARMC8 significantly inhibited osteosarcoma cell proliferation in vitro and markedly inhibited xenograft tumor growth in vivo. ARMC8 silencing also suppressed the epithelial-mesenchymal transition (EMT) phenotype, as well as inhibited the migration and invasion of osteosarcoma cells. Furthermore, knockdown of ARMC8 obviously inhibited the expression of beta-catenin, c-Myc, and cyclin D1 in MG-63 cells. In conclusion, this report demonstrates that ARMC8 silencing inhibits proliferation and invasion of osteosarcoma cells. Therefore, ARMC8 may play an important role in the development and progression of human osteosarcoma and may represent a novel therapeutic target in the treatment of osteosarcoma. PMID- 27712596 TI - MicroRNA-221-3p Plays an Oncogenic Role in Gastric Carcinoma by Inhibiting PTEN Expression. AB - Gastric carcinoma is one of the most common malignancies in men, and microRNA plays a critical role in regulating the signaling networks of gastric carcinoma tumorigenesis and metastasis. We first report the functional characteristics of miR-221-3p in gastric carcinoma. Quantification in gastric carcinoma cell lines and tumor samples reveals significantly increasing miR-221-3p expression. Moreover, a high level of miR-221-3p is correlated with a poor prognosis for gastric carcinoma patients. Ectopic miR-221-3p expression significantly promotes gastric carcinoma cell proliferation, invasion, and sphere formation, while silencing miR-221-3p significantly inhibits these abilities in gastric carcinoma cells. Tests in vivo showed that miR-221-3p significantly promotes tumor growth in xenograft mouse models. In this study, we reveal that miR-221-3p targets PTEN mRNA and downregulates PTEN, which is the possible mechanism of miR-221-3p induced oncogenic properties. Collectively, we reveal a critical role for miR-221 3p in gastric carcinoma development and progression. PMID- 27712597 TI - Knockdown of Latent Transforming Growth Factor-beta (TGF-beta)-Binding Protein 2 (LTBP2) Inhibits Invasion and Tumorigenesis in Thyroid Carcinoma Cells. AB - Latent transforming growth factor-beta (TGF-beta)-binding protein 2 (LTBP2) is one of four proteins in the LTBP family of proteins (LTBP1-4) and was shown to play a vital role in tumorigenesis. However, little is known regarding the functional role of LTBP2 in thyroid carcinoma. Therefore, the current study aimed to evaluate the effect of LTBP2 expression on the proliferation, invasion, and tumorigenesis in thyroid carcinoma cells and to explore the molecular mechanism of LTBP2 in tumor progression. Our results showed that the expression of LTBP2 is upregulated in human thyroid carcinoma and cell lines. Knockdown of LTBP2 inhibits the proliferation, invasion, and EMT phenotype in thyroid carcinoma cells. Furthermore, knockdown of LTBP2 attenuates thyroid carcinoma growth in nude mice. Finally, knockdown of LTBP2 inhibits activation of the PI3K/Akt pathway in thyroid carcinoma cells. In summary, the present study has provided further evidence that knockdown of LTBP2 inhibits invasion and tumorigenesis in thyroid carcinoma cells. Our findings may help to further elucidate the molecular mechanisms underlying thyroid carcinoma progression and provide candidate targets for the prevention and treatment of thyroid carcinoma. PMID- 27712599 TI - Exosomes Derived From Hypoxic Colorectal Cancer Cells Promote Angiogenesis Through Wnt4-Induced beta-Catenin Signaling in Endothelial Cells. AB - Cancer cell-derived exosomes have been actively released into the tumor microenvironment with pleiotropic roles in tumor growth and metastasis, including angiogenesis and immune modulation. However, the functions and underlying mechanisms of exosomes shed by colorectal cancer (CRC) cells under hypoxic conditions remain unknown. Here we found that exosomes derived from hypoxic CRC cells promoted the proliferation and migration of endothelial cells. Suppression of exosome secretion through RAB27a knockdown in CRC cells inhibited exosomal induced proliferation and migration of endothelial cells. Furthermore, we discovered that these exosomes enriched with Wnt4 were dependent on HIF1alpha. Exosomal Wnt4 increased beta-catenin nuclear translocation in endothelial cells. The induction of beta-catenin signaling is critical for the proliferation and migration of endothelial cells, which could be abolished by the inhibitor ICG001. The in vivo animal study further revealed the tumor-promoting effects of CRC cell derived exosomes with enhanced tumor growth and angiogenesis. Taken together, our study indicates that CRC cells promote angiogenesis through exosome-mediated Wnt/beta-catenin signaling in endothelial cells under hypoxia, which might be a new mechanism in CRC development. PMID- 27712600 TI - Empty Spiracles Homeobox 2 (EMX2) Inhibits the Invasion and Tumorigenesis in Colorectal Cancer Cells. AB - Empty spiracles homeobox 2 (EMX2) is a homeodomain-containing transcription factor that plays an essential role in tumorigenesis. However, to the best of our knowledge, the role of EMX2 in human colorectal cancer (CRC) is still unclear. Thus, the aim of this study was to investigate the expression and role of EMX2 in CRC. Our results demonstrated that the expression of EMX2 was greatly decreased in CRC tissues and cell lines. Overexpression of EMX2 significantly inhibited the proliferation in vitro and CRC tumor growth in nude mice. In addition, EMX2 also inhibited the migration and invasion of CRC cells. Mechanically, overexpression of EMX2 downregulated the expression levels of beta-catenin, cyclin D1, and c-Myc in CRC cells. Taken together, our study demonstrates that EMX2 inhibits proliferation and tumorigenesis through inactivation of the Wnt/beta-catenin pathway in CRC cells. Therefore, EMX2 may be a potential therapeutic target for the treatment of CRC. PMID- 27712601 TI - The Quality Measurement Crisis: An Urgent Need for Methodological Standards and Transparency. PMID- 27712602 TI - Consumer Rankings and Health Care: Toward Validation and Transparency. AB - BACKGROUND: Differences between the Centers for Medicare & Medicaid Services (CMS)-measured rates of safety events for Rush University Medical Center (RUMC; Chicago) and the U. S. News & World Report (USNWR)-deter mined patient safety score were evaluated in an attempt to validate the USNWR patient safety score based ranking. METHODS: The USNWR findings for Patient Safety Indicators (PSIs) were compared with findings derived from RUMC internal billing data, and sensitivity analyses were conducted using a simulated data set derived from the Healthcare Cost and Utilization Project (HCUP) state inpatient data sets. RESULTS: Discrepancies were found for PSIs 3 (Pressure Ulcer Rate), 9 (Perioperative Hemorrhage or Hematoma Rate), and 11 (Postoperative Respiratory Failure Rate)-an excess of 0.72, 0.63, and 0.26 cases/1,000 admissions, in USNWR versus RUMC, respectively). The sensitivity analysis, which included missing present on admission (POA) flags and dates, resulted in an increase of rates by 1.83 (95% confidence interval [CI] = 1.10-2.56) cases/1,000 hospital- izations, 2.72 (CI = 0.00-5.90) cases/1,000 hospitalizations, and 3.89 (CI = 1.60-6.20) cases/1,000 hospitalizations for PSI 3, 9, and 11, respectively. Regression modeling showed that each 1% increase in transfers was associated with an in- crease of 0.06 cases of PSI 3/1,000 admissions; each 1,000 increase in admissions was associated with an increase of 0.04 cases of PSI 9/1,000 admissions. CONCLUSION: The USNWR data set produced inaccurate PSI rates for RUMC, and false positive event rates were more common among high-transfer and high-volume hos- pitals. More transparency and validation is needed for con- sumer-based benchmarking methods. In response to these findings and concerns raised by others, in 2016 USNWR made changes to its methodology and data sources and reported them in announcing its 2016-17 Best Hospitals. PMID- 27712604 TI - A New Performance Improvement Model: Adding Benchmarking to the Analysis of Performance Indicator Data. AB - BACKGROUND: A performance improvement model was developed that focuses on the analysis and interpretation of performance indicator (PI) data using statistical process control and benchmarking. PIs are suitable for comparison with benchmarks only if the data fall within the statistically accepted limit-that is, show only random variation. Specifically, if there is no significant special-cause variation over a period of time, then the data are ready to be benchmarked. METHODS: The proposed Define, Measure, Control, Internal Threshold, and Benchmark model is adapted from the Define, Measure, Analyze, Improve, Control (DMAIC) model. The model consists of the following five steps: Step 1. Define the process; Step 2. Monitor and measure the variation over the period of time; Step 3. Check the variation of the process; if stable (no significant variation), go to Step 4; otherwise, control variation with the help of an action plan; Step 4. Develop an internal threshold and compare the process with it; Step 5.1. Compare the process with an internal benchmark; and Step 5.2. Compare the process with an external benchmark. RESULTS: The steps are illustrated through the use of health care-associated infection (HAI) data collected for 2013 and 2014 from the Infection Control Unit, King Fahd Hospital, University of Dammam, Saudi Arabia. CONCLUSION: Monitoring variation is an important strategy in understanding and learning about a process. In the example, HAI was monitored for variation in 2013, and the need to have a more predictable process prompted the need to control variation by an action plan. The action plan was successful, as noted by the shift in the 2014 data, compared to the historical average, and, in addition, the variation was reduced. The model is subject to limitations: For example, it cannot be used without benchmarks, which need to be calculated the same way with similar patient populations, and it focuses only on the "Analyze" part of the DMAIC model. PMID- 27712603 TI - Viewing Prevention of Catheter-Associated Urinary Tract Infection as a System: Using Systems Engineering and Human Factors Engineering in a Quality Improvement Project in an Academic Medical Center. AB - BACKGROUND: Urinary tract infections (UTIs) are the most commonly reported health care-associated infection (HAI) in the United States. Among UTIs acquired in the hospital, approximately 75% are associated with urinary catheters, with an estimated 15%-25% of all hospitalized patients receiving urinary catheters during their hospitalization. Despite ambitious national goals to reduce these infections, catheter-associated urinary tract infection (CAUTI) has not decreased in the United States. METHODS: Systems engineering (SE) and human factors engi- neering (HFE) methods were used to reduce urinary catheter utilization and CAUTIs in a three-year (June 1, 2012-May 31, 2015) quality improvement project in a 610 bed academic medical center. These methods were used to define the factors leading to CAUTI and promote standardization of urinary catheter utilization, insertion, and maintenance. RESULTS: The total systemwide CAUTI count decreased from 135 cases at baseline to 74 cases at the end of the project's Year 1, to 59 cases at the end of Year 2, and 25 cases at the end of Year 3-alone, an 81.5% reduction from baseline. The control chart showed a steady decline in the CAUTI count within a few months after the project's start. By the end of Year 3, on the basis of an average attributable-per-patient cost of CAUTI ($1,007 per case), the estimated annual avoidable CAUTI costs decreased from approximately $135,945 to $25,175 per year. Urinary catheter utilization decreased by 27.3% during the same three-year period, and the systemwide CAUTI standardized infection ratio (SIR) decreased from 3.2 to 0.51 (84.1% from baseline). CONCLUSION: SE and HFE methods and principles can effectively decrease urinary catheter utilization and CAUTI incidence in an academic medical center hospital environment. PMID- 27712605 TI - Creating a Professional Ladder for Interpreters for Improvement of Care. AB - BACKGROUND: Children's Hospital Los Angeles (CHLA), a metropolitan academic medical center, recognized limitations in how the professional interpreters from the Diversity Services Department were used to support effective patient-provider communication across the organization. Given the importance of mitigating language and communication barriers, CHLA sought to minimize clinical and structural barriers to health care for limited English proficiency populations through a comprehensive restructuring of the Diversity Services Department. This approach entailed a new delivery model for hospital language assistance and cultural consultancy resources. METHODS: The intervention focused on restructuring the Diversity Services Department, redefining priorities, reallocating resources, and redefining the roles of the language staff positions in the department. The language staff role was redesigned to fit a four-level professional career ladder modeled after the professional career ladders commonly used in hospitals for the RN role and other professional disciplines. The approach involved creating new levels of language specialist, each with progressive requirements for performance, leadership, and accountability for patient care outcomes. Language staff in the inpatient, clinic, and emergency department settings worked alongside nurses, physicians, and other disciplines to care for a specific set of patients. RESULTS: The result of this work was a positive culture change resulting in service efficiencies, care improvements, and improved access to language services. CONCLUSIONS: A professional career ladder for language staff contributed to improving the quality and access of language services and advancing the interpreting profession by incorporating care coordination support, vital document translation, and cultural consultancy.

PMID- 27712610 TI - Contextual factors in geosocial-networking smartphone application use and engagement in condomless anal intercourse among gay, bisexual, and other men who have sex with men who use Grindr. AB - : Background Geosocial-networking smartphone applications (apps) have been used increasingly by men who have sex with men (MSM) to meet new sexual partners. The purpose of this study was to examine associations between contexts of app use (e.g. using apps when drinking) and condomless anal intercourse among a sample of MSM who use these apps. METHODS: MSM (n=174) in New York City were recruited through Grindr, a geosocial-networking app popular among MSM, using broadcast advertisements asking MSM to complete an Internet-based survey about their app use and sexual behaviours. Log-binomial regression models were fit to assess the association between each of the six app-use contexts (e.g. using apps when lonely, when drinking) and engagement in condomless insertive and receptive anal intercourse with one or more partners in the past 3 months. RESULTS: Engagement in condomless receptive and insertive anal intercourse with one or more partners in the preceding 3 months was common (39.7% and 43.1% respectively) and was associated with several app-use contexts. For example, significant associations (P<0.05) were observed between alcohol and other drug use when using these apps and engagement in condomless receptive and insertive anal intercourse. CONCLUSION: Given that 57.5% of respondents had engaged in condomless anal intercourse in the preceding 3 months and the associations of app-use contexts with condomless sexual behaviours, these findings suggest that reductions in substance use may lead to safer sexual practices among MSM who use apps to meet sexual partners. PMID- 27712611 TI - Social participation as an indicator of successful aging: an overview of concepts and their associations with health. AB - Objectives Social participation has generated a wealth of research in gerontology, but the concept suffers from a lack of conceptual clarity that renders it difficult to define and measure. This means that research on social participation is difficult to compare directly. The aim of the present study was to draw the literature on social participation in older adults together to inform health services researchers seeking to investigate social participation as an indicator of successful aging. Methods A narrative review of studies investigating the association between social participation and health in adults aged 65 years and older was conducted. Results Three concepts of social participation (i.e. social connections, informal social participation and volunteering) were defined, their measurement instruments described and evidence of their associations with health explored. All three concepts have demonstrated associations with an array of health indicators. Prospective studies reveal that social participation at baseline is positively associated with mental and physical health. Conclusion A model of social participation on health is presented, showing the evidence that all three concepts contribute to the association between social participation and health through their shared mechanisms of social support and social cohesion with the wider community. Using an instrument that can be separated into these three distinct concepts will assist health services researchers to determine the relative effect of each form of participation on the health of older adults. What is known about the topic? Social participation has generated a wealth of research in gerontology. The scope of the literature on social participation is broad and the concepts diverse. For this reason, most previous systematic reviews have been unable to comprehensively assess the effect of all concepts of social participation on health. This means the research on social participation is difficult to compare directly, and indicators of social participation in older adults are difficult for policy makers to select. What does this paper add? This paper overviews the three concepts of social participation, their methods of measurement and their associations with health in older adults. We present a model of social participation that incorporates all three concepts of social participation and their effects on health. We argue that the use of a measure that can be segmented into each of the three forms of social participation will predict more of the variance in health outcomes than any measure on its own. What are the implications for practitioners? Enhancing the social participation of older adults is a key factor in successful aging that many older adults value. However, many service provision organisations tend to focus on meeting the specific physical needs of clients, rather than targeting services that connect older adults with their community. Targeting social participation may present one of the greatest opportunities to improve older adults' general health, and will also generate societal benefits by increasing community contributions from this group. Selecting an indicator of social participation that measures each of the three concepts overviewed in this paper will enable policy makers to identify the areas in which social interventions for older adults will have the most effect. PMID- 27712612 TI - Prevalence of oral human papillomavirus in men attending an Italian sexual health clinic. AB - A high-risk population, formed by 79 consecutive male attendees of our sexually transmissible infections clinic, and who did not have any overt signs of human papillomavirus (HPV) infection, were examined. Oral HPV prevalence (37%) was much higher than previously reported. Periurethral HPV-DNA was found in 49% of the patients and anal HPV-DNA was found in 43% of the patients. Considering the high prevalence of oral HPV obtained in the current study, it is important to further investigate the burden of oral HPV, not only in men who have sex with men, but also in heterosexual men and in women. PMID- 27712613 TI - Exploring attitudes towards sexting of young people: a cross-sectional study. AB - : Background Sexting is a common emerging phenomenon. This study aims to explore young people's attitudes towards sexting. METHODS: Participants (n=469, age range 15-29 years) were recruited at a music festival and self-completed a questionnaire. Attitudes towards sexting were assessed using a series of seven statements, rated on a five-point Likert scale from 'strongly agree' to 'strongly disagree'. Correlates of sexting attitudes were determined using multivariable regression. RESULTS: Forty-six percent of respondents reported ever sexting. Most (88%) agreed 'It's risky for a girl to send a naked picture of herself,' fewer agreed with the statement 'It's risky for a boy to send a naked picture of himself' (77%). Thirty percent agreed that 'If someone I'd just started seeing sent me a sext I might show it to some friends,' however, only 14% might do the same with a sext from a boyfriend or girlfriend (this did not differ by sex). More permissive attitudes to sexting were associated with being male, lower sexual health knowledge, inconsistent condom use with casual partners, and higher alcohol consumption. CONCLUSIONS: Although the majority of young people surveyed agreed that sexting was risky it was a common practice. Given the potential psychosocial impact of sharing sexts without consent, it was concerning that up to a third of participants indicated they might do so. The findings of this study have implications for informing education on sexting. PMID- 27712614 TI - Seasonal variation in gonorrhoea incidence among men who have sex with men. AB - : Background After reviewing urethral gonorrhoea cases among men who have sex with men (MSM) at the South Australia Specialist Sexual Health (SASSH) in Adelaide, Australia, we noticed peaks of gonorrhoea among MSM occurred predominantly in the first quarter of the year (January-March). The aim of this study was to formally test this hypothesis against data from a similar period at three sexual health services, one each in Adelaide, Melbourne and Sydney. METHODS: This study was a retrospective analysis of computerised records at the three Australian sexual health services. Potential risk factors for urethral gonorrhoea among MSM were also reviewed at the SASSH. RESULTS: More peaks of gonorrhoea cases were observed in the first quarter of the year in Adelaide and Sydney and in the second and fourth quarter in Melbourne. Factors independently associated with urethral gonorrhoea at the SASSH were being a young MSM, especially those aged 25-29 (odds ratio (OR) 2.66, 95% confidence interval (CI): 2.00-3.54), having more than one sexual partner (OR 1.71, 95% CI: 1.43-2.04), having had sex interstate and overseas (OR 1.52, 95% CI: 1.06-2.17), and presenting in the first quarter (OR 1.30, 95% CI: 1.10-1.55). CONCLUSION: Our data suggest that gonorrhoea among MSM occurs in a seasonal pattern, particularly late summer into early autumn. This has implications for the provision of health services over the year and for the timing of health promotion activities. PMID- 27712615 TI - Integration of nurse practitioners using a change management framework: the way forward. AB - Objective The aim of the present study was to investigate and describe the application of a change management theoretical framework in relation to nurse practitioner (NP) role integration. Methods A survey formed Phase 1 of a broader mixed-methods study to explore perceptions of the change process involved with integrating NPs into Australian health care settings. The stakeholder participants were NPs, nurse managers and nurse policy advisers. Results Key themes were identified adding information about how NPs, nurse managers and nurse policy advisers perceive the integration of NPs into Australian healthcare. The themes correlate to the components of organisational change management necessary to embed NPs into the healthcare workforce. Conclusions Healthcare reform is a complex organisational change. Alignment of several key elements is required for the process to be successful. A change management proposal for reframing organisations provides an apt framework for use in the Australian context of reforming workforce to integrate NPs into healthcare teams. The theoretical framework proposes that multiple lenses be applied to change processes, to integrate NPs into the workforce and highlights the need for exceptional leadership throughout such endeavours. What is known about the topic? NPs provide safe and efficient care to patients, often in settings where access to health care is limited. NPs have been identified as a key strategic workforce reform initiative to address some of the known healthcare gaps. What does this paper add? This paper adds information about how NPs, nurse managers and nurse policy advisers perceive progress of the integration of NPs into healthcare settings. The findings are contextualised within an organisational change framework and highlight the complexity of healthcare reform. What are the implications for practitioners? The findings provide a novel approach for managing workforce reform and identify the components of change management necessary to embed NPs into the healthcare workforce. PMID- 27712616 TI - The future of drugs: recreational drug use and sexual health among gay and other men who have sex with men. AB - There are complex historical connections between sexual minoritisation and desires to chemically alter bodily experience. For gay men, drug and alcohol use can be a creative or experimental response to social marginalisation - and not necessarily a problematic one in every instance. Numerous studies have found that infection with HIV and other sexually transmissible infections (STIs) is more likely among gay and men who have sex with men (MSM) who use recreational drugs than those who do not, but the causal nature of these relations is uncertain. Sexualised drug use is associated with a range of other problems, including dependence, mental health issues, accident and overdose. A growing body of work in the Alcohol and Other Drugs (AOD) field demonstrates the action of drugs and their purported effects to be a product of their relations with various other actors, contexts and practices. Given these contingencies, it is impossible to predict the future of drugs or their effect on the sexual health of gay and MSM with any degree of certainty. This article outlines some of the conditions most likely to mediate such futures in the medium term. Public funding for lesbian, gay, bisexual, transgender and queer drug issues should not remain restricted to questions of HIV prevention and sexual health. It should be expanded to equip sexual health and AOD service providers with the cultural and sexual literacy to mitigate stigma and allow them to respond constructively to drug problems among sexual and gender minorities as a matter of priority. PMID- 27712617 TI - What is the extent of repeat prescriptions for post-exposure prophylaxis for HIV after sexual exposure among men who have sex with men in the UK? AB - People who repeatedly present for post-exposure prophylaxis (PEP) for prevention of HIV following a high-risk sexual exposure are of concern according to the British HIV Association PEP guidelines. The aim of this audit was to determine the extent of repeat PEP prescriptions for men who have sex with men (MSM) by conducting a retrospective review of patient notes from a 5-year period at one genitourinary medicine clinic. Over the 5 years, 107 of 929 MSM (11.5%; 95% confidence interval: 9.45-13.55) received more than one PEP prescription (repeat range 1-8; mean=3.3, s.d.=1.44). Forty percent of these had received three or more PEP prescriptions. Seven of the 107 became HIV positive. Patients need to be offered and encouraged to take up behavioural risk reduction interventions at the time of each PEP prescription. PMID- 27712618 TI - Sexual transmission of hepatitis C virus among gay and bisexual men: a systematic review. AB - A systematic review was performed on the evidence of sexual transmission of hepatitis C virus (HCV) in gay and bisexual men (GBM). Studies conducted in industrialised countries and published in English from 2000 to 2015 with data on HCV in GBM were included. Pooled estimates of prevalence and incidence of HCV infection were stratified by study settings and participants' HIV status using random effect models. Case-series reports were summarised descriptively. Of the 38 cross-sectional studies, the pooled HCV prevalence was substantially higher in HIV-positive men (8.3%, 95% CI: 6.7-9.9) than in HIV-negative men (1.5%, 95% CI 0.8-2.1), and higher in those who reported injecting drug use (34.8%, 95% CI 26.9 42.7) than in those who did not (3.5%, 95% CI 2.4-4.5). Of the 16 longitudinal studies, the pooled HCV incidence was markedly higher in clinic-based (7.0 per 1000 person-years, 95% CI 4.6-9.5) than in community-based (1.4 per 1000 person years, 95% CI 0.7-2.1) studies, and in HIV-positive men (6.4 per 1000 person years, 95% CI 4.6-8.1) than in HIV-negative men (0.4 per 1000 person-years, 95% CI 0-0.9). Since the early 2000s, 15 case-series reports increasingly pointed to the importance of sexual transmission of HCV in mainly HIV-positive men. Injecting drug use remained the major transmission route of HCV in GBM. Receptive condomless intercourse and concurrent ulcerative sexually transmissible infections are likely drivers that facilitated HCV sexual transmission in HIV positive men. HCV incidence remains very low in HIV-negative GBM. PMID- 27712619 TI - Organizing graduate medical education programs into communities of practice. AB - BACKGROUND: A new organizational model of educational administrative support was instituted in the Department of Medical Education (DME) to better meet increasing national accreditation demands. Residency and fellowship programs were organized into four 'Communities of Practice' (CoOPs) based on discipline similarity, number of learners, and geographic location. Program coordinator reporting lines were shifted from individual departments to a centralized reporting structure within the DME. The goal of this project was to assess the impact on those most affected by the change. METHODS: This was a mixed methods study that utilized structured interviews and the Organizational Culture Assessment Instrument (OCAI). Eleven members of the newly formed CoOPs participated in the study. RESULTS: Three major themes emerged after review and coding of the interview transcripts: improved group identity, improved availability of resources, and increased opportunity for professional growth. OCAI results indicated that respondents are committed to the DME and perceived the culture to be empowering. The 'preferred culture' was very similar to the culture at the time of the study, with some indication that DME employees are ready for more creativity and innovation in the future. CONCLUSION: Reorganization within the DME of residency programs into CoOPs was overwhelmingly perceived as a positive change. Improved resources and accountability may position our DME to better handle the increasing complexity of graduate medical education. PMID- 27712621 TI - Supramolecular Architecture of the Coronavirus Particle. AB - Coronavirus particles serve three fundamentally important functions in infection. The virion provides the means to deliver the viral genome across the plasma membrane of a host cell. The virion is also a means of escape for newly synthesized genomes. Lastly, the virion is a durable vessel that protects the genome on its journey between cells. This review summarizes the available X-ray crystallography, NMR, and cryoelectron microscopy structural data for coronavirus structural proteins, and looks at the role of each of the major structural proteins in virus entry and assembly. The potential wider conservation of the nucleoprotein fold identified in the Arteriviridae and Coronaviridae families and a speculative model for the evolution of corona-like virus architecture are discussed. PMID- 27712620 TI - The experiences of patients with Duchenne muscular dystrophy in facing and learning about their clinical conditions. AB - Patients experience extreme difficulty when facing an intractable genetic disease. Herein, we examine the experiences of patients with Duchenne muscular dystrophy in facing and learning about their disease. A total of seven patients with Duchenne muscular dystrophy (age range: 20-48) participated. We conducted in depth interviews with them about how they learned of their disease and how their feelings regarding the disease changed over time. Transcribed data were analysed using thematic analysis. The following themes emerged from this analysis: "experiences before receiving the diagnosis," "experiences when they learned of their condition and progression of the disease," "supports," and "desired explanations." Anxiety and worry were most pronounced when they had to transition to using wheelchairs or respirators due to disease progression; indeed, such transitions affect the patients psychological adjustment. In such times, support from significant others in their lives helped patients adjust. PMID- 27712622 TI - Coronavirus cis-Acting RNA Elements. AB - Coronaviruses have exceptionally large RNA genomes of approximately 30 kilobases. Genome replication and transcription is mediated by a multisubunit protein complex comprised of more than a dozen virus-encoded proteins. The protein complex is thought to bind specific cis-acting RNA elements primarily located in the 5'- and 3'-terminal genome regions and upstream of the open reading frames located in the 3'-proximal one-third of the genome. Here, we review our current understanding of coronavirus cis-acting RNA elements, focusing on elements required for genome replication and packaging. Recent bioinformatic, biochemical, and genetic studies suggest a previously unknown level of conservation of cis acting RNA structures among different coronavirus genera and, in some cases, even beyond genus boundaries. Also, there is increasing evidence to suggest that individual cis-acting elements may be part of higher-order RNA structures involving long-range and dynamic RNA-RNA interactions between RNA structural elements separated by thousands of nucleotides in the viral genome. We discuss the structural and functional features of these cis-acting RNA elements and their specific functions in coronavirus RNA synthesis. PMID- 27712624 TI - Feline Coronaviruses: Pathogenesis of Feline Infectious Peritonitis. AB - Feline infectious peritonitis (FIP) belongs to the few animal virus diseases in which, in the course of a generally harmless persistent infection, a virus acquires a small number of mutations that fundamentally change its pathogenicity, invariably resulting in a fatal outcome. The causative agent of this deadly disease, feline infectious peritonitis virus (FIPV), arises from feline enteric coronavirus (FECV). The review summarizes our current knowledge of the genome and proteome of feline coronaviruses (FCoVs), focusing on the viral surface (spike) protein S and the five accessory proteins. We also review the current classification of FCoVs into distinct serotypes and biotypes, cellular receptors of FCoVs and their presumed role in viral virulence, and discuss other aspects of FIPV-induced pathogenesis. Our current knowledge of genetic differences between FECVs and FIPVs has been mainly based on comparative sequence analyses that revealed "discriminatory" mutations that are present in FIPVs but not in FECVs. Most of these mutations result in amino acid substitutions in the S protein and these may have a critical role in the switch from FECV to FIPV. In most cases, the precise roles of these mutations in the molecular pathogenesis of FIP have not been tested experimentally in the natural host, mainly due to the lack of suitable experimental tools including genetically engineered virus mutants. We discuss the recent progress in the development of FCoV reverse genetics systems suitable to generate recombinant field viruses containing appropriate mutations for in vivo studies. PMID- 27712625 TI - Interaction of SARS and MERS Coronaviruses with the Antiviral Interferon Response. AB - Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) are the most severe coronavirus (CoV)-associated diseases in humans. The causative agents, SARS-CoV and MERS-CoV, are of zoonotic origin but may be transmitted to humans, causing severe and often fatal respiratory disease in their new host. The two coronaviruses are thought to encode an unusually large number of factors that allow them to thrive and replicate in the presence of efficient host defense mechanisms, especially the antiviral interferon system. Here, we review the recent progress in our understanding of the strategies that highly pathogenic coronaviruses employ to escape, dampen, or block the antiviral interferon response in human cells. PMID- 27712627 TI - Coronavirus Spike Protein and Tropism Changes. AB - Coronaviruses (CoVs) have a remarkable potential to change tropism. This is particularly illustrated over the last 15 years by the emergence of two zoonotic CoVs, the severe acute respiratory syndrome (SARS)- and Middle East respiratory syndrome (MERS)-CoV. Due to their inherent genetic variability, it is inevitable that new cross-species transmission events of these enveloped, positive-stranded RNA viruses will occur. Research into these medical and veterinary important pathogens-sparked by the SARS and MERS outbreaks-revealed important principles of inter- and intraspecies tropism changes. The primary determinant of CoV tropism is the viral spike (S) entry protein. Trimers of the S glycoproteins on the virion surface accommodate binding to a cell surface receptor and fusion of the viral and cellular membrane. Recently, high-resolution structures of two CoV S proteins have been elucidated by single-particle cryo-electron microscopy. Using this new structural insight, we review the changes in the S protein that relate to changes in virus tropism. Different concepts underlie these tropism changes at the cellular, tissue, and host species level, including the promiscuity or adaptability of S proteins to orthologous receptors, alterations in the proteolytic cleavage activation as well as changes in the S protein metastability. A thorough understanding of the key role of the S protein in CoV entry is critical to further our understanding of virus cross-species transmission and pathogenesis and for development of intervention strategies. PMID- 27712623 TI - Viral and Cellular mRNA Translation in Coronavirus-Infected Cells. AB - Coronaviruses have large positive-strand RNA genomes that are 5' capped and 3' polyadenylated. The 5'-terminal two-thirds of the genome contain two open reading frames (ORFs), 1a and 1b, that together make up the viral replicase gene and encode two large polyproteins that are processed by viral proteases into 15-16 nonstructural proteins, most of them being involved in viral RNA synthesis. ORFs located in the 3'-terminal one-third of the genome encode structural and accessory proteins and are expressed from a set of 5' leader-containing subgenomic mRNAs that are synthesized by a process called discontinuous transcription. Coronavirus protein synthesis not only involves cap-dependent translation mechanisms but also employs regulatory mechanisms, such as ribosomal frameshifting. Coronavirus replication is known to affect cellular translation, involving activation of stress-induced signaling pathways, and employing viral proteins that affect cellular mRNA translation and RNA stability. This chapter describes our current understanding of the mechanisms involved in coronavirus mRNA translation and changes in host mRNA translation observed in coronavirus infected cells. PMID- 27712626 TI - Molecular Basis of Coronavirus Virulence and Vaccine Development. AB - Virus vaccines have to be immunogenic, sufficiently stable, safe, and suitable to induce long-lasting immunity. To meet these requirements, vaccine studies need to provide a comprehensive understanding of (i) the protective roles of antiviral B and T-cell-mediated immune responses, (ii) the complexity and plasticity of major viral antigens, and (iii) virus molecular biology and pathogenesis. There are many types of vaccines including subunit vaccines, whole-inactivated virus, vectored, and live-attenuated virus vaccines, each of which featuring specific advantages and limitations. While nonliving virus vaccines have clear advantages in being safe and stable, they may cause side effects and be less efficacious compared to live-attenuated virus vaccines. In most cases, the latter induce long lasting immunity but they may require special safety measures to prevent reversion to highly virulent viruses following vaccination. The chapter summarizes the recent progress in the development of coronavirus (CoV) vaccines, focusing on two zoonotic CoVs, the severe acute respiratory syndrome CoV (SARS CoV), and the Middle East respiratory syndrome CoV, both of which cause deadly disease and epidemics in humans. The development of attenuated virus vaccines to combat infections caused by highly pathogenic CoVs was largely based on the identification and characterization of viral virulence proteins that, for example, interfere with the innate and adaptive immune response or are involved in interactions with specific cell types, such as macrophages, dendritic and epithelial cells, and T lymphocytes, thereby modulating antiviral host responses and viral pathogenesis and potentially resulting in deleterious side effects following vaccination. PMID- 27712628 TI - The Nonstructural Proteins Directing Coronavirus RNA Synthesis and Processing. AB - Coronaviruses are animal and human pathogens that can cause lethal zoonotic infections like SARS and MERS. They have polycistronic plus-stranded RNA genomes and belong to the order Nidovirales, a diverse group of viruses for which common ancestry was inferred from the common principles underlying their genome organization and expression, and from the conservation of an array of core replicase domains, including key RNA-synthesizing enzymes. Coronavirus genomes (~26-32 kilobases) are the largest RNA genomes known to date and their expansion was likely enabled by acquiring enzyme functions that counter the commonly high error frequency of viral RNA polymerases. The primary functions that direct coronavirus RNA synthesis and processing reside in nonstructural protein (nsp) 7 to nsp16, which are cleavage products of two large replicase polyproteins translated from the coronavirus genome. Significant progress has now been made regarding their structural and functional characterization, stimulated by technical advances like improved methods for bioinformatics and structural biology, in vitro enzyme characterization, and site-directed mutagenesis of coronavirus genomes. Coronavirus replicase functions include more or less universal activities of plus-stranded RNA viruses, like an RNA polymerase (nsp12) and helicase (nsp13), but also a number of rare or even unique domains involved in mRNA capping (nsp14, nsp16) and fidelity control (nsp14). Several smaller subunits (nsp7-nsp10) act as crucial cofactors of these enzymes and contribute to the emerging "nsp interactome." Understanding the structure, function, and interactions of the RNA-synthesizing machinery of coronaviruses will be key to rationalizing their evolutionary success and the development of improved control strategies.

PMID- 27712631 TI - Role of Neuroinflammation in Parkinson Disease: The Enigma Continues. PMID- 27712632 TI - Physician Attitudes About Maintenance of Certification: A Cross-Specialty National Survey. AB - OBJECTIVES: To determine physicians' perceptions of current maintenance of certification (MOC) activities and to explore how perceptions vary across specialties, practice characteristics, and physician characteristics, including burnout. PATIENTS AND METHODS: We conducted an Internet and paper survey among a national cross-specialty random sample of licensed US physicians from September 23, 2015, through April 18, 2016. The questionnaire included 13 MOC items, 2 burnout items, and demographic variables. RESULTS: Of 4583 potential respondents, we received 988 responses (response rate 21.6%) closely reflecting the distribution of US physician specialties. Twenty-four percent of physicians (200 of 842) agreed that MOC activities are relevant to their patients, and 15% (122 of 824) felt they are worth the time and effort. Although 27% (223 of 834) perceived adequate support for MOC activities, only 12% (101 of 832) perceived that they are well-integrated in their daily routine and 81% (673 of 835) believed they are a burden. Nine percent (76 of 834) believed that patients care about their MOC status. Forty percent or fewer agreed that various MOC activities contribute to their professional development. Attitudes varied statistically significantly (P<.001) across specialties, but reflected low perceived relevance and value in nearly all specialties. Thirty-eight percent of respondents met criteria for being burned out. We found no association of attitudes toward MOC with burnout, certification status, practice size, rural or urban practice location, compensation model, or time since completion of training. CONCLUSION: Dissatisfaction with current MOC programs is pervasive and not localized to specific sectors or specialties. Unresolved negative perceptions will impede optimal physician engagement in MOC. PMID- 27712633 TI - Reduced Risk of Parkinson Disease in Patients With Rheumatoid Arthritis: A Nationwide Population-Based Study. AB - OBJECTIVE: To investigate the association between rheumatoid arthritis (RA) and the risk of developing Parkinson disease (PD). PATIENTS AND METHODS: This retrospective cohort study was conducted from January 1, 1998, through December 31, 2010, using data from the Taiwan National Health Insurance Research Database. We identified 33,221 patients with newly diagnosed RA and 132,884 randomly selected age- and sex-matched patients without RA. A multivariable Cox proportional hazards regression model was used to evaluate the risk of developing PD in the RA cohort. RESULTS: The multivariable Cox proportional hazards regression analysis revealed an adjusted hazard ratio of 0.65 (95% CI, 0.58-0.73) for the development of PD in the RA cohort relative to the non-RA cohort. The cumulative incidence of PD was 2.42% lower in the RA cohort than in the non-RA cohort. The risk reduction of PD development in patients affected with RA was independent of treatment with disease-modifying antirheumatic drugs (DMARDs); subgroup analysis of patients treated with biologic DMARDs revealed further risk reduction (adjusted hazard ratio, 0.57; 95% CI, 0.41-0.79). CONCLUSION: Patients with RA have a reduced risk of developing PD. This risk reduction was independent of treatment with DMARDs; however, biologic DMARDs appear to further reduce this risk. Further research is necessary to explore the underlying mechanism. PMID- 27712634 TI - Systemic Immunoglobulin Light Chain Amyloidosis-Associated Myopathy: Presentation, Diagnostic Pitfalls, and Outcome. AB - OBJECTIVE: To characterize the natural history of immunoglobulin light chain amyloidosis-associated myopathy and to provide guidelines for recognition. PATIENTS AND METHODS: Fifty-one patients with systemic immunoglobulin light chain amyloidosis and biopsy-confirmed muscle amyloid deposition diagnosed between January 1, 1995, and December 31, 2015, were included in this study. RESULTS: Common presenting symptoms were muscle weakness in 49 patients (96%), dysphagia in 23 (45%), myalgia in 17 (33%), macroglossia in 17 (33%), jaw claudication in 13 (25%), and hoarseness in 9 (18%). The median time from the onset of symptoms to diagnosis was almost 2 years. Less than two-thirds of the patients with an outside muscle biopsy (16 of 27) had an established pathologic confirmation of amyloidosis due to failure to routinely incorporate Congo red staining. Moreover, 12 patients were incorrectly treated before diagnosis of amyloid myopathy. More than half of the patients had normal creatine kinase levels at diagnosis. Cardiac troponin T levels were elevated above the reference range in 5 of 12 patients who lacked evidence of cardiac involvement. Median overall survival was 32 months. Factors associated with inferior survival were involvement of more than 2 organs (median survival, 13 months), cardiac involvement (median survival, 15 months), and absence of stem cell transplant (median survival, 18 months). With the exclusion of patients treated with stem cell transplant, no improvement in survival was seen over the 1995-2004 and 2005-2015 decades. CONCLUSION: Immunoglobulin light chain amyloidosis-associated myopathy is rare. Delay in diagnosis is common, and there is a high rate of pathologic and clinical misdiagnosis. Awareness of elevation of cardiac troponin T levels in the absence of cardiac disease may be a clue to diagnosis. PMID- 27712636 TI - Diet Quality and Mortality Risk in Metabolically Obese Normal-Weight Adults. AB - OBJECTIVE: To examine the associations among the Dietary Approaches to Stop Hypertension (DASH)-style diet, the Healthy Eating Index (HEI), and mortality risk in metabolically obese normal-weight (MONW) adults. PATIENTS AND METHODS: Data were from normal-weight (body mass index of 18.5 to <25) adults aged 30 to 90 years at baseline in the Third National Health and Nutrition Examination Survey, October 18, 1988, through October 15, 1994, followed up for deaths (all cause, cardiovascular, and cancer related) until December 31, 2011. A total of 2103 participants without known cardiovascular disease and cancer at baseline were included in this prospective cohort study. Metabolic obesity was defined as having 2 or more of the following: high glucose, blood pressure, triglyceride, C reactive protein, and insulin resistance values and low high-density lipoprotein cholesterol levels; metabolic healthy status was defined as having 0 or 1 of these metabolic derangements. RESULTS: During median follow-up of 18.6 years, there were 344 and 296 deaths in the MONW and metabolically healthy normal-weight (MHNW) phenotypes, respectively. In MONW individuals, a 1-SD increment in adherence to a DASH diet (2 points) or HEI (14 points) was significantly associated with reductions (17% [hazard ratio (HR), 0.83; 95% CI, 0.72-0.97] and 22% [HR, 0.78; 95% CI, 0.68-0.90], respectively) in the risk of all-cause mortality, after adjustment for potential confounders. The corresponding HRs for cardiovascular disease mortality were 0.72 (95% CI, 0.55-0.94) and 0.79 (95% CI, 0.65-0.97), respectively. In addition, reduction of cancer mortality was observed with 1-SD increment of HEI (HR, 0.63; 95% CI, 0.46-0.88). However, no association was observed in the MHNW phenotype. Sensitivity analyses suggested relationships robust to different definitions of MONW and also dose responses with the number of metabolic derangements. CONCLUSION: Higher diet quality scores were associated with lower risk of mortality in normal-weight individuals with metabolic abnormalities. PMID- 27712637 TI - Survival, Risk Factors, and Effect of Treatment in 101 Patients With Calciphylaxis. AB - OBJECTIVE: To report on the survival and the associations of treatments upon survival of patients with calciphylaxis seen at a single center. PATIENTS AND METHODS: Using the International Classification of Diseases, Ninth Revision diagnosis code of 275.49 and the keyword "calciphylaxis" in the dismissal narrative, we retrospectively identified 101 patients with calciphylaxis seen at our institution between January 1, 1999, through September 20, 2014, using a predefined, consensus-developed classification scheme. RESULTS: The average age of patients was 60 years: 81 (80.2%) were women; 68 (68.0%) were obese; 19 (18.8%) had stage 0 to 2 chronic kidney disease (CKD), 19 (18.9%) had stage 3 or 4 CKD; 63 (62.4%) had stage 5 or 5D (dialysis) CKD. Seventy-five patients died during follow-up. Six-month survival was 57%. Lack of surgical debridement was associated with insignificantly lower 6-month survival (hazard ratio [HR]=1.99; 95% CI, 0.96-4.15; P=.07) and significantly poorer survival for the entire duration of follow-up (HR=1.98; 95% CI, 1.15-3.41; P=.01), which was most pronounced in stage 5 or 5D CKD (HR=1.91; 95% CI, 1.03-3.56; P=.04). Among patients with stage 5/5D CKD, subtotal parathyroidectomy (performed only in patients with hyperparathyroidism) was associated with better 6-month (HR=0.12; 95% CI, 0.02-0.90; P=.04) and overall survival (HR= 0.37; 95% CI, 0.15-0.87; P=.02). CONCLUSION: Calciphylaxis is associated with a high mortality rate. Significantly effective treatments included surgical debridement and subtotal parathyroidectomy in patients with stage 5/5D CKD with hyperparathyroidism. Treatments with tissue-plasminogen activator, sodium thiosulfate, and hyperbaric oxygen therapy were not associated with higher mortality. PMID- 27712635 TI - A Predictive Model of Mortality in Patients With Bloodstream Infections due to Carbapenemase-Producing Enterobacteriaceae. AB - OBJECTIVE: To develop a score to predict mortality in patients with bloodstream infections (BSIs) due to carbapenemase-producing Enterobacteriaceae (CPE). PATIENTS AND METHODS: A multinational retrospective cohort study (INCREMENT project) was performed from January 1, 2004, through December 31, 2013. Patients with clinically relevant monomicrobial BSIs due to CPE were included and randomly assigned to either a derivation cohort (DC) or a validation cohort (VC). The variables were assessed on the day the susceptibility results were available, and the predictive score was developed using hierarchical logistic regression. The main outcome variable was 14-day all-cause mortality. The predictive ability of the model and scores were measured by calculating the area under the receiver operating characteristic curve. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated for different cutoffs of the score. RESULTS: The DC and VC included 314 and 154 patients, respectively. The final logistic regression model of the DC included the following variables: severe sepsis or shock at presentation (5 points); Pitt score of 6 or more (4 points); Charlson comorbidity index of 2 or more (3 points); source of BSI other than urinary or biliary tract (3 points); inappropriate empirical therapy and inappropriate early targeted therapy (2 points). The score exhibited an area under the receiver operating characteristic curve of 0.80 (95% CI, 0.74-0.85) in the DC and 0.80 (95% CI, 0.73-0.88) in the VC. The results for 30-day all-cause mortality were similar. CONCLUSION: A validated score predictive of early mortality in patients with BSIs due to CPE was developed. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT01 764490. PMID- 27712638 TI - Calciphylaxis: A Disease of Pannicular Thrombosis. AB - OBJECTIVE: To identify coagulation risk factors in patients with calciphylaxis and the relationship between anticoagulation use and overall survival. PATIENTS AND METHODS: Study subjects were 101 patients with calciphylaxis seen at Mayo Clinic from 1999 to September 2014. Data including thrombophilia profiles were extracted from the medical records of each patient. Survival status was determined using patient registration data and the Social Security Death Index. Survival was estimated using the Kaplan-Meier method, and associations were evaluated using Cox proportional hazards models. RESULTS: Sixty-four of the 101 patients underwent thrombophilia testing. Of these, a complete test panel was performed in 55 and a partial panel in 9. Severe thrombophilias observed in 60% (33 of 55) of the patients included antiphospholipid antibody syndrome protein C, protein S, or antithrombin deficiencies or combined thrombophilias. Of the 55 patients, severe thrombophilia (85%, 23 of 27) was noted in patients who were not on warfarin at the time of testing (27). Nonsevere thrombophilias included heterozygous factor V Leiden (n=2) and plasminogen deficiency (n=1). For the comparison of survival, patients were divided into 3 treatment categories: Warfarin (n=63), other anticoagulants (n=20), and no anticoagulants (n=18). There was no statistically significant survival difference between treatment groups. CONCLUSION: Laboratory testing reveals a strikingly high prevalence of severe thrombophilias in patients with calciphylaxis, underscoring the importance of congenital and acquired thrombotic propensity potentially contributing to the pathogenesis of this disease. These findings may have therapeutic implications; however, to date, survival differences did not vary by therapeutic choice. PMID- 27712639 TI - Antithrombotic Approaches in Acute Coronary Syndromes: Optimizing Benefit vs Bleeding Risks. AB - It is estimated that in the United States, each year, approximately 620,000 persons will experience an acute coronary syndrome and approximately 70% of these will have non-ST-elevation acute coronary syndrome. Cardiovascular disease still accounts for 1 of every 3 deaths in the United States, and there is an urgent need to improve the prognosis of patients presenting with acute coronary syndrome. Cardiovascular mortality and ischemic complications are common after acute coronary syndrome, and the advent of newer antithrombotic therapies has reduced ischemic complications, but at the expense of greater bleeding. The new antithrombotic agents also raise the challenge of choosing between multiple potential therapeutic combinations to minimize recurrent ischemia without a concomitant increase in bleeding, a decision that often varies according to an individual patient's relative propensity for ischemia versus hemorrhage. In this review, we will synthesize the available information to arm health care providers with the contemporary knowledge on antithrombotic therapy and individualize treatment decisions. PMID- 27712640 TI - Importance of Rapid Eye Movement Sleep Behavior Disorder to the Primary Care Physician. AB - Sleep disorders and neurodegenerative diseases are commonly encountered in primary care. A common, but underdiagnosed sleep disorder, rapid eye movement sleep behavior disorder (RBD), is highly associated with Parkinson disease and related disorders. Rapid eye movement sleep behavior disorder is common. It is estimated to affect 0.5% of the general population and more than 7% of individuals older than 60 years; however, most cases go unrecognized. Rapid eye movement sleep behavior disorder presents as dream enactment, often with patients thrashing, punching, and kicking while they are sleeping. Physicians can quickly assess for the presence of RBD with high sensitivity and specificity by asking patients the question "Have you ever been told that you act out your dreams, for example by punching or flailing your arms in the air or screaming and shouting in your sleep?" Patients with RBD exhibit subtle signs of neurodegenerative disease, such as mild motor slowing, constipation, or changes in sense of smell. These signs and symptoms may predict development of a neurodegenerative disease within 3 years. Ultimately, most patients with RBD develop a neurodegenerative disease, highlighting the importance of serial neurological examinations to assess for the presence of parkinsonism and/or cognitive impairment and prognostic counseling for these patients. Rapid eye movement sleep behavior disorder is treatable with melatonin (3-6 mg before bed) or clonazepam (0.5-1 mg before bed) and may be the most common, reversible cause of sleep-related injury. Thus, it is important to identify patients at risk of RBD in a primary care setting so that bedroom safety can be addressed and treatment may be initiated.

PMID- 27712641 TI - Anorectal and Pelvic Pain. AB - Although pelvic pain is a symptom of several structural anorectal and pelvic disorders (eg, anal fissure, endometriosis, and pelvic inflammatory disease), this comprehensive review will focus on the 3 most common nonstructural, or functional, disorders associated with pelvic pain: functional anorectal pain (ie, levator ani syndrome, unspecified anorectal pain, and proctalgia fugax), interstitial cystitis/bladder pain syndrome, and chronic prostatitis/chronic pelvic pain syndrome. The first 2 conditions occur in both sexes, while the latter occurs only in men. They are defined by symptoms, supplemented with levator tenderness (levator ani syndrome) and bladder mucosal inflammation (interstitial cystitis). Although distinct, these conditions share several similarities, including associations with dysfunctional voiding or defecation, comorbid conditions (eg, fibromyalgia, depression), impaired quality of life, and increased health care utilization. Several factors, including pelvic floor muscle tension, peripheral inflammation, peripheral and central sensitization, and psychosocial factors, have been implicated in the pathogenesis. The management is tailored to symptoms, is partly supported by clinical trials, and includes multidisciplinary approaches such as lifestyle modifications and pharmacological, behavioral, and physical therapy. Opioids should be avoided, and surgical treatment has a limited role, primarily in refractory interstitial cystitis. PMID- 27712645 TI - Foreword: Child Health Disparities. PMID- 27712646 TI - Child Health Disparities in the 21st Century. AB - The topic of persistent child health disparities remains a priority for policymakers and a concern for pediatric clinicians. Health disparities are defined as differences in adverse health outcomes for specific health indicators that exist across sub-groups of the population, frequently between minority and majority populations. This review will highlight the gains that have been made since the 1990s as well as describe disparities that have persisted or have worsened into the 21st century. It will also examine the most potent social determinants and their impact on the major disparities in mortality, preventive care, chronic disease, mental health, educational outcomes, and exposure to selected environmental toxins. Each section concludes with a description of interventions and innovations that have been successful in reducing child health disparities.

PMID- 27712648 TI - Impact of Lipoprotein(a) on Long-term Outcomes in Patients With Diabetes Mellitus Who Underwent Percutaneous Coronary Intervention. AB - Patients with diabetes mellitus (DM) are at twofold to fourfold higher cardiovascular risk than those without DM. Serum levels of lipoprotein(a) (Lp(a)) can be risk factors for adverse events. However, the clinical implications of Lp(a) in patients with DM who underwent percutaneous coronary intervention (PCI) is unknown. The aim of the study was to determine the role of Lp(a) in patients with DM who underwent PCI. A total of 3,508 patients were treated by PCI from 1997 to 2011 at our institution. Among them, we analyzed consecutive 1,546 patients with DM. Eligible 1,136 patients were divided into 2 groups (high Lp(a) [n = 575] and low Lp(a) [n = 561]) by the median of Lp(a) levels. The number of chronic kidney disease, multivessel disease, and the level of LDL-C were higher in the group with high Lp(a) than with low Lp(a). The median follow-up period was 4.7 years. Event rate of all-cause death was same between the 2 groups (p = 0.37). However, cumulative incidence of cardiac death and acute coronary syndrome was significantly higher in the high Lp(a) than in the low Lp(a) group (p = 0.03). Multivariable analysis selected a high Lp(a) level as an independent predictor of cardiac death and acute coronary syndrome (hazard ratio 1.20; 95% confidence interval 1.00 to 1.42; p = 0.04). In conclusion, a high Lp(a) value could be associated with advanced cardiac events after PCI for patients with DM. PMID- 27712650 TI - Effects of NMDA and non-NMDA ionotropic glutamate receptors in the medial preoptic area on body temperature in awake rats. AB - Glutamate when microinjected at the medial preoptic area (mPOA) influences brain temperature (Tbr) and body temperature (Tb) in rats. Glutamate and its various receptors are present at the mPOA. The aim of this study was to identify the contribution of each of the ionotropic glutamatergic receptors at the mPOA on changes in Tbr and Tb in freely moving rats. Adult male Wistar rats (n=40) were implanted with bilateral guide cannula with indwelling styli above the mPOA. A telemetric transmitter was implanted at the peritoneum to record Tb and locomotor activity (LMA). A precalibrated thermocouple wire implanted near the hypothalamus was used to assess Tbr. Specific agonist for each ionotropic glutamate receptor was microinjected into the mPOA and its effects on temperature and LMA were measured in the rats. The rats were also microinjected with the respective ionotropic receptor antagonists, 15min prior to the microinjection of each agonist. Amongst amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), N methyl-d-aspartate (NMDA) and kainic acid, AMPA increased Tb and LMA when injected at the mPOA. Specific antagonists for AMPA receptors was able to attenuate this increase (p<0.005). Pharmacological blockade of NMDA was able to lower Tbr only. Microinjection of kainic acid and its antagonist had no effect on the variables. The finding of the study suggests that activation of the AMPA receptors at the mPOA, leads to the rise in body temperature. PMID- 27712651 TI - Cooler performance breadth in a viviparous skink relative to its oviparous congener. AB - Susceptibility of species to climate change varies depending on many biological and environmental traits, such as reproductive mode and climatic exposure. For example, wider thermal tolerance breadths are associated with more climatically variable habitats and viviparity could be associated with greater vulnerability relative to oviparity. However, few examples exist detailing how such physiological and environmental traits together might shape species thermal performance. In this study we compared the thermal tolerance and performance of two sympatric skink congeners in Hong Kong that differ in habitat use and reproductive mode. The viviparous Sphenomorphus indicus lives on the forest floor while the oviparous Sphenomorphus incognitus occupies stream edges. We quantified the thermal environments in each of these habitats to compare climatic exposure and then calculated thermal safety margins, potential daily activity times within each species' thermal optimal range, and possible climate change vulnerability. Although we did not detect any differences in thermal tolerance range or thermal environments across habitats, we found cooler performance in S. indicus relative to S. incognitus. Moreover, while optimal activity time increases for both skinks under a warming scenario, we project that the thermal safety margin of S. indicus would narrow to nearly zero, thus losing its buffering capacity to potential extreme climate events in the future. This research is thus consistent with recent studies emphasizing the vulnerability of viviparous reptiles to a warming climate. The results together furthermore highlight the complexity in how environmental and physiological traits at multiple spatial scales structure climate change vulnerability of ectothermic species. PMID- 27712649 TI - High-Sensitivity C-Reactive Protein and Risk of Stroke in Atrial Fibrillation (from the Reasons for Geographic and Racial Differences in Stroke Study). AB - The relation between inflammation and prothrombotic state in atrial fibrillation (AF) is well recognized. This suggests a potential role for high-sensitivity C reactive protein (hs-CRP), a marker of systemic inflammation, in improving prediction of stroke in participants with AF. Cox proportional hazard analysis was used to examine the risk of stroke in 25,841 participants (40% black and 55% women) with and without AF who were enrolled in the Reasons for Geographic and Racial Differences in Stroke study from 2003 to 2007. Baseline AF (n = 2,132) was ascertained by electrocardiogram and self-reported history of previous physician diagnosis. Stroke events were identified and adjudicated during 8.3 years of follow-up. A total of 655 incident strokes occurred during follow-up. In a model adjusted for sociodemographics, traditional stroke risk factors, and use of aspirin and warfarin, higher levels of hs-CRP were associated with increased overall stroke risk (hazard ratio [HR] 1.30, 95% confidence interval [CI] 1.10 to 1.54, and HR 1.06, 95% CI 1.01 to 1.12 for hs-CRP >3 mg/L and per 1-SD increase, respectively). Higher levels of hs-CRP continued to be associated with incident stroke in participants without AF (HR 1.31, 95% CI 1.09 to 1.57, and HR 1.06, 95% CI 1.01 to 1.12 for hs-CRP >3 mg/L and per 1-SD increase, respectively) but not in those with AF (HR 1.22, 95% CI 0.78 to 1.91, and HR 1.01, 95% CI 0.82 to 1.23 for hs-CRP >3 mg/L and per 1-SD increase, respectively). In conclusion, although hs-CRP was significantly associated with stroke risk in this population, it seems to be limited to those without AF. These findings suggest a limited value of hs CRP in improving stroke risk stratification in subjects with AF. PMID- 27712652 TI - Life-history responses of the rice stem borer Chilo suppressalis to temperature change: Breaking the temperature-size rule. AB - Temperature is a key environmental factor for ectotherms and affects a large number of life history traits. In the present study, development time from hatching to pupation and adult eclosion, pupal and adult weights of the rice stem borer, Chilo suppressalis were examined at 22, 25, 28 and 31 degrees C under L18:D 6. Larval and pupal times were significantly decreased with increasing rearing temperature and growth rate was positively correlated with temperature. Larval and pupal developmental times were not significantly different between females and males. The relationship between body weight and rearing temperature in C. suppressalis did not follow the temperature-size rule (TSR), both males and females gained the highest body weight at 31 degrees C. Females were significantly larger than males at all temperatures, showing a female biased sex size dimorphism (SSD). Contrary to Rensch's rule, SSD and body weight in C. suppressalis tended to increase with rising temperature. Male pupae lost significantly more weight at metamorphosis compared to females. We discuss the adaptive significance of the reverse-TSR in the moth's life history. PMID- 27712653 TI - The influence of cooling and TRPM8 ion channel activation on the level of pro inflammatory cytokines in normotensive and hypertensive rats. AB - The role of thermosensitive TRP ion channels in physiological processes in the whole organism is far from being clear. In present work we tried to understand the possible participation of the cold-sensitive ion channel TRPM8 in regulation of the pro-inflammatory cytokine level in blood, and to see if hypertension (widely spread disease) changes this relationship. Experiments were carried out on normotensive Wistar rats and rats with inherited stress-induced arterial hypertension. The effects of deep rapid and slow cooling with decrease in rectal temperature by 3 degrees C, and activation of the skin TRPM8 ion channel by its agonist menthol (application of 1% L-menthol) on the concentration of pro inflammatory cytokines (IL-6, IL-1beta and TNFalpha) in blood have been studied. The data have shown that the TRPM8 ion channel participates in regulation of pro inflammatory cytokine in the whole organism, as well as exposure to cold. In normotensive animals the activation of the cold-sensitive TRPM8 ion channel in skin by its agonist menthol without any temperature shifts causes an increase (about two fold) of pro-inflammatory cytokines IL-6 and IL-1 beta in blood without any changes in the level of TNFalpha. The effect of cooling (slow or rapid) on IL-6 and IL-1beta is comparable with the effect of the TRPM8 activation. The changes in TNFalpha concentration were observed only at slow cooling. In hypertensive rats there were no changes in the level of pro inflammatory cytokines under the effect of cooling or activation of the TRPM8 ion channel. This evidences for the decrease in TRPM8 activity under arterial hypertension. One of possible mechanisms of profound changes at arterial hypertension may be the alteration in activity of some ion channels, and TRPM8 is one of them. PMID- 27712654 TI - Thermal and substrate color-induced melanization in laboratory reared red-eared sliders (Trachemys scripta elegans). AB - Color and pigmentation patterns of the integument can facilitate crypsis, thermoregulation, and social signaling. According to the "thermal melanism hypothesis", cold environmental temperature should increase the quantity of melanin that is deposited in the integument thereby facilitating radiative warming. We studied the influences of water temperature (26 degrees C or 31 degrees C) and substrate color (black or white) on the degree of melanization in the red-eared slider, Trachemys scripta elegans, under laboratory conditions. Turtles reared on a black substrate, or in 26 degrees C water, for 120 days were darker than those reared on a white substrate or in 31 degrees C water. A potential tradeoff between the fitness benefits of crypsis and the benefits of radiative warming through melanism was detected because turtles reared in 26 degrees C water and on a white substrate were darker than those reared on a white substrate and in 31 degrees C water. Low temperatures limited metabolic processes because turtles reared in 26 degrees C water grew more slowly than those reared in 31 degrees C water. However, histological analyses revealed that melanization was a dynamic process in all treatments confirming that the degree of melanization in the cool water treatment was not influenced by the initial and relatively dark hatchling coloration in individuals that grew relatively slowly. PMID- 27712655 TI - Comparison of abdominal skin temperature between fertile and infertile women by infrared thermography: A diagnostic approach. AB - This retrospective study aimed to evaluate the differences in abdominal temperature (AT) between fertile (n=206; age) and infertile (n=250) women between the ages of 30 and 39 years. We evaluated the differences in two distinctive skin temperatures by thermography: DeltaT1 (CV8 index) - difference in temperature between the mid-abdomen (CV8 acupuncture area) and ventral upper arm (VUA) and DeltaT2 (CV4 index) - difference in temperature between the lower abdomen (CV4 acupuncture area) and VUA. The results indicated that the DeltaT1 and DeltaT2 of infertile women were significantly lower (by 1.05 degrees C and 0.79 degrees C, respectively; p<0.001, both) compared to those of fertile women. Additionally, the area under the curve of DeltaT1 (0.78) was greater compared to that of DeltaT2 (0.736), and its threshold was set at 0.675 degrees C, by which, the sensitivity and specificity of DeltaT1 for determination of fertility were found to be 80.8% and 68.4%, respectively. In conclusion, infertility is associated with lower AT. The decrease in AT in infertile women might be due to poor blood perfusion to the core muscles and tissues of the body. These findings provide a basis for further research for evaluation of clinical feasibility of thermography for analysis of infertility in women. Further evaluation of the influence of AT on fertility outcomes is required to determine the causal relationship between AT and infertility. PMID- 27712656 TI - Numerical investigation of thermal response of laser-irradiated biological tissue phantoms embedded with gold nanoshells. AB - The work presented in this paper focuses on numerically investigating the thermal response of gold nanoshells-embedded biological tissue phantoms with potential applications into photo-thermal therapy wherein the interest is in destroying the cancerous cells with minimum damage to the surrounding healthy cells. The tissue phantom has been irradiated with a pico-second laser. Radiative transfer equation (RTE) has been employed to model the light-tissue interaction using discrete ordinate method (DOM). For determining the temperature distribution inside the tissue phantom, the RTE has been solved in combination with a generalized non Fourier heat conduction model namely the dual phase lag bio-heat transfer model. The numerical code comprising the coupled RTE-bio-heat transfer equation, developed as a part of the current work, has been benchmarked against the experimental as well as the numerical results available in the literature. It has been demonstrated that the temperature of the optical inhomogeneity inside the biological tissue phantom embedded with gold nanoshells is relatively higher than that of the baseline case (no nanoshells) for the same laser power and operation time. The study clearly underlines the impact of nanoshell concentration and its size on the thermal response of the biological tissue sample. The comparative study concerned with the size and concentration of nanoshells showed that 60nm nanoshells with concentration of 5*1015mm-3 result into the temperature levels that are optimum for the irreversible destruction of cancer infected cells in the context of photo-thermal therapy. To the best of the knowledge of the authors, the present study is one of the first attempts to quantify the influence of gold nanoshells on the temperature distributions inside the biological tissue phantoms upon laser irradiation using the dual phase lag heat conduction model. PMID- 27712657 TI - Effects of rapid temperature fluctuations prior to breeding on reproductive efficiency in replacement gilts. AB - Rapidly cooling pigs after heat stress (HS) results in a pathophysiological condition, and because rapid temperature fluctuations may be associated with reduced reproductive success in sows, it lends itself to the hypothesis that these conditions may be linked. Objectives were to determine the effects of rapid cooling on thermal response and future reproductive success in pigs. Thirty-six replacement gilts (137.8+/-0.9kg BW) were estrus synchronized and then 14.1+/-0.4 d after estrus confirmation, pigs were exposed to thermoneutral conditions (TN; n=12; 19.7+/-0.9 degrees C) for 6h, or HS (36.3+/-0.5 degrees C) for 3h, followed by 3h of rapid cooling (HSRC; n=12; immediate TN exposure and water dousing) or gradual cooling (HSGC; n=12; gradual decrease to TN conditions) repeated over 2 d. Vaginal (TV) and gastrointestinal tract temperatures (TGI) were obtained every 15min, and blood was collected on d 1 and d 2 during the HS and recovery periods at 180 and 60min, respectively. Pigs were bred 8.3+/-0.8 d after thermal treatments over 2 d. Reproductive tracts were collected and total fetus number and viability were recorded 28.0+/-0.8 d after insemination. HS increased TV and TGI (P=0.01; 0.98 degrees C) in HSRC and HSGC compared to TN pigs. During recovery, TV was reduced from 15 to 105min (P=0.01; 0.33 degrees C) in HSRC compared to HSGC pigs, but no overall differences in TGI were detected (P<0.05; 39.67 degrees C). Rapid cooling increased (P<0.05) TNFalpha compared to HSGC and TN pigs during recovery-d 1 (55.2%), HS-d 2 (35.1%), and recovery-d 2 (64.9%). Viable fetuses tended to be reduced (P=0.08; 10.5%) and moribund fetuses tended to be increased (P=0.09; 159.3%) in HSRC compared to HSGC and TN pigs. In summary, rapid cooling prior to breeding may contribute to reduced fetal viability and reproductive success in pigs. PMID- 27712658 TI - Effect of thermal stress on fertility and egg quality of Japanese quail. AB - Heat stress is one of the major causes of a decreased performance of laying quail in tropical and subtropical countries. The aim of this study was to investigate the impact of temperature humidity index (THI) on fertility aspects, external and internal egg quality parameters in Japanese quail. One hundred and forty four (144) Japanese quail, 12 of weeks age, were used. Birds were divided randomly into three equal groups, control (at low THI, lower than 70), H1 (at moderate THI, 70-75) and H2 (at high THI, 76-80). Quail in the control and H1 groups had significant greater fertility (p=0.021) and hatchability % (p=0.037), compared with H2 group. Quail in the control group (at low THI) laid heavier egg weight with a higher external (egg weight (p=0.03), shell thickness, shell weight, eggshell ratio and eggshell density (p=0.001)) and internal egg quality score (albumin weight (p=0.026), yolk height (p=0.003), yolk index (p=0.039) and Haugh unit (p=0.001)). Otherwise, such quality traits were compromised in heat-stressed quail. At the high THI level, egg weight had a significant positive correlation with albumin weight (r=0.58, p<0.01), yolk weight (r=0.22, p<0.05), albumen ratio (r=0.17, p<0.05), yolk height (r=0.14, p<0.05) and yolk index (r=0.18, p<0.05), but was negatively correlated with yolk ratio (r=-0.15, p<0.05). Japanese quail exposed to heat stress (THI over 75) revealed drop in fertility indices and egg quality traits, indicating a detrimental policy of economic income. PMID- 27712659 TI - Sexual differences in behavioral thermoregulation of the lizard Scelarcis perspicillata. AB - Temperature determines all aspects of the biology of ectotherms. Although sexual differences in thermal ecology are not the rule in lizards, some species exhibit such differences. We studied the effect of sex and reproductive condition on the thermoregulation of an introduced population of Scelarcis perspicillata during the summer in Menorca (Balearic Islands, Spain). These lizards live in the wall surfaces of a limestone quarry, where the sun is scarce because of the narrowness of the quarry walls. The population is sexually dimorphic, with larger males than females. We measured body temperature (Tb) of adult males and females in the field, and air (Ta) and substrate temperature (Ts) at the capture sites, and recorded exposure to sunlight, height of the perch, and type of substrate. We also recorded operative temperatures (Te) as a null hypothesis of thermoregulation. Finally, we studied the thermal preferences of adult males and females in a laboratory thermal gradient. Thermal preferences were similar for pregnant and non-pregnant females, and sex did not affect the thermal preferences of lizards, even after controlling for the effect of body size. However, in the field, females achieved higher Tb than males, and occupied microhabitats with higher Ta and Ts and lower perch heights than males. Furthermore, females selected perches in full sun at a higher frequency than males. As a consequence, females achieved a higher accuracy and effectiveness of thermoregulation (0.89) than males (0.84). Thus, all else being equal, females would achieve a higher performance than males. The observed results are attributable to sexual differences in behaviour, probably in relation with the reproductive season. PMID- 27712660 TI - Effect of cyclical cold stress during embryonic development on aspects of physiological responses and HSP70 gene expression of chicks. AB - The objective of the present study was to evaluate the effects of cyclical lower incubation temperature at different embryonic ages on the hatchability, body and organs weights, thyroid hormones, and liver HSP70 gene expression of newly hatched chicks. In a completely randomized design, fertile eggs of a broiler breeder (34 weeks of age) were assigned to three treatment groups with six replicates and 145 eggs per each. The treatment groups were as: control group (C) that eggs were incubated at 37.6 degrees C during the whole incubation period; incubation temperature was decreased to 36 degrees C for 3h per day at embryonic age from 12 to 14 (T1); and incubation temperature was decreased to 36 degrees C for 3h per day at embryonic age from 15 to 17 (T2). No significant difference was found among treatments for hatchability (P>0.05). There were no differences (P>0.05) among treatments for body weight and liver weight, while heart weight of chicks in T1 and T2 groups were significantly higher than the control group (P<0.05). There were no differences (P>0.05) among treatments for the levels of thyroid hormones, however, the levels of both hormones tended to increase in chicks exposed to cold stress (T1 and T2). Chicks in T2 group had higher liver HSP70 gene expression compared with those in T1 and the control group (P<0.05). Cold stress in both incubation periods had no significant effect on the plasma levels of aspartate aminotransferase and alanine aminotransferase. Treatments had no effect on the plasma levels of glucose, cholesterol and triglyceride. The results of this study suggest that cyclical lower incubation temperatures (36 degrees C) at the embryonic age from day 15-17 could induce the liver HSP70 gene expression, without negative effects on the hatchability and body weight of hatched chicks. PMID- 27712661 TI - The particularities of a remote islet shape the thermoregulatory profile of an endemic Mediterranean lizard. AB - Environmental temperatures considerably affect the reptilian ability for thermoregulation and harsh climatic conditions may impose a highly effective body temperature regulation to lizards. Such demanding conditions are more common to extreme mainland habitats (e.g. deserts or mountains). To the contrary, islands have more benign climate conditions thanks to the thermal buffering effect of the surrounding sea. However, this favorable effect may be eliminated in small size islets where the scarcity of thermal shelters and exposure to high winds create challenging conditions. Here we investigate the impact of a tough islet habitat on the thermoregulation of Podarcis levendis, a lacertid lizard endemic to two rocky islets in the north Cretan Sea, Greece. To evaluate the thermoregulatory effectiveness of P. levendis we measured operative and body temperatures in the field and the preferred body temperatures in the lab. Analyses of the thermal data revealed an accurate, precise, and effective thermoregulator, achieving very high thermoregulation values (E =0.91, de--db- =7.6). This high effectiveness comes to compensate living in an inhospitable habitat as the operative temperatures denote (de =7.79). Our findings, together with the limited published literature, suggested the lack of a general pattern for all insular lizards and indicated a possible deviation for islet habitats. PMID- 27712662 TI - Effect of stride frequency on thermoregulatory responses during endurance running in distance runners. AB - Changing stride frequency may influence oxygen uptake and heart rate during running as a function of running economy and central command. This study investigated the influence of stride frequency manipulation on thermoregulatory responses during endurance running. Seven healthy endurance runners ran on a treadmill at a velocity of 15km/h for 60min in a controlled environmental chamber (ambient temperature 27 degrees C and relative humidity 50%), and stride frequency was manipulated. Stride frequency was intermittently manipulated by increasing and decreasing frequency by 10% from the pre-determined preferred frequency. These periods of increase or decrease were separated by free frequency running in the order of free stride frequency, stride frequency manipulation (increase or decrease), free stride frequency, and stride frequency manipulation (increase or decrease) for 15min each. The increased and decreased stride frequencies were 110% and 91% of the free running frequency, respectively (196+/ 6, 162+/-5, and 178+/-5steps/min, respectively, P<0.01). Compared to the control, stride frequency manipulation did not affect rectal temperature, heart rate, or the rate of perceived exhaustion during running. Whole-body sweat loss increased significantly when stride frequency was manipulated (1.48+/-0.11 and 1.57+/ 0.11kg for control and manipulated stride frequencies, respectively, P<0.05), but stride frequency had a small effect on sweat loss overall (Cohen's d=0.31). A higher mean skin temperature was also observed under mixed frequency conditions compared to that in the control (P<0.05). While the precise mechanisms underlying these changes remain unknown (e.g. running economy or central command), our results suggest that manipulation of stride frequency does not have a large effect on sweat loss or other physiological variables, but does increase mean skin temperature during endurance running. PMID- 27712663 TI - Whole- and partial-body cryostimulation/cryotherapy: Current technologies and practical applications. AB - Cold therapy is commonly used as a method to relieve pain and inflammation. This review focuses primarily on two methods of cold therapy that have received recent attention: whole-body cryotherapy and partial-body cryotherapy. These methods are used to induce physiological and psychological benefits in humans in the context of medicine, health and sports. The subjects experiencing cryotherapy are dressed in minimal clothing and are exposed to very cold air (at -110 degrees C or less) for 1-4min. Despite the increasing scientific interest in these methods, there is a lack of information about the technologies used. Moreover, there is no existing reference concerning exposure protocols and the relationship between temperature, duration, number of repetitions and the treatments' desired effects. The aim of this review is to compare whole- and partial-body cryotherapy effects (especially on skin temperature) and to classify the protocols for exposure according to the desired effects. This review emphasises 1) the lack of information concerning the actual temperatures inside the cabin or chamber during exposure and 2) the heterogeneity among the exposure protocols that have been reported in the scientific literature. This review will be valuable and relevant to health professionals endeavouring to optimize the cold treatments offered to patients and producers of cryotherapy apparatus striving to create more efficient devices that meet market requirements. PMID- 27712664 TI - Evaluation of physiological strain in hot work areas using thermal imagery. AB - BACKGROUND: Monitoring core body temperature to identify heat strain in workers engaged in hot work in heat stress environments is intrusive and expensive. Nonintrusive, inexpensive methods are needed to calculate individual Physiological Strain Index (PSI). OBJECTIVE: Thermal imaging and heart rate monitoring were used in this study to calculate Physiological Strain Index (PSI) from thermal imaging temperatures of human subjects wearing thermal protective garments during recovery from hot work. METHODS: Ten male subjects were evaluated for physiological strain while participating in hot work. Thermal images of the head and neck were captured with a high-resolution thermal imaging camera concomitant with measures of gastrointestinal and skin temperature. Lin's concordance correlation coefficient (rho_c), Pearson's coefficient (r) and bias correction factor (C-b) were calculated to compare thermal imaging based temperatures to gastrointestinal temperatures. Calculations of PSI based thermal imaging recorded temperatures were compared to gastrointestinal based PSI. RESULTS: Participants reached a peak PSI of 5.2, indicating moderate heat strain. Sagittal measurements showed low correlation (rho_c=0.133), moderate precision (r=0.496) and low accuracy (C_b=0.269) with gastrointestinal temperature. Bland Altman plots of imaging measurements showed increasing agreement as gastrointestinal temperature rose; however, the Limits of Agreement (LoA) fell outside the +/-0.25C range of clinical significance. Bland-Altman plots of PSI calculated from imaging measurements showed increasing agreement as gastrointestinal temperature rose; however, the LoA fell outside the +/-0.5 range of clinical significance. CONCLUSION: Results of this study confirmed previous research showing thermal imagery is not highly correlated to body core temperature during recovery from moderate heat strain in mild ambient conditions. Measurements display a trend toward increasing correlation at higher body core temperatures. Accuracy was not sufficient at mild to moderate heat strain to allow calculation of individual physiological stress. PMID- 27712665 TI - Proteomic response of mouse pituitary gland under heat stress revealed active regulation of stress responsive proteins. AB - The mapping of tissue proteomes can identify the molecular regulators and effectors of their physiological activity. However, proteomic response of a mammalian tissue against heat stress (HS) particularly of the pituitary gland has not yet been resolved. The proteomic response of the mouse pituitary gland against HS at 40oC was evaluated by iTRAQ. We found that, HS actively regulates stress-related proteins. Among 375 differentially expressed proteins, 26 up and 46 downregulated proteins were found as stress responsive proteins. Two proteins belonging to the HSP70 and one to HSP90 family were found upregulated. Meanwhile, the expression of HSP90alpha (Cytosolic), HSP60, and HSP84b were observed to be downregulated. A neuroprotective enzyme Nmnat3 was observed to be significantly upregulated. Three proteins related to the intermediate filament (IF) proteins (lamins, vimentin and keratins) were also found to be upregulated. We reported, an association between the IF proteins and HSPs as a biological marker of HS. The expression of Apo A-IV was upregulated and might be one explanation for low food intake during HS. Our findings indicated that, differentially expressed proteins might be played important roles in combating HS. PMID- 27712666 TI - Altitudinal variation in lifespan of Drosophila melanogaster populations from the Firtina Valley, northeastern Turkey. AB - Studies of altitudinal changes in phenotype and genotype can complement studies of latitudinal patterns and provide evidence of natural selection in response to climatic factors. In Drosophila melanogaster, latitudinal variation in phenotype and genotype has been well studied, but altitudinal patterns have rarely been investigated. We studied populations from six different altitudes varying between 35m and 2173m in the Firtina Valley in northeastern part of Turkey to evaluate clinal trends in lifespan under experimental conditions. Lifespan in the D. melanogaster populations was examined in relation to altitude, sex, temperature (25 degrees C and 29 degrees C), and dietary yeast concentration (5g/L and 25g/L). As expected high temperature decrease lifespan in all populations. However, it was shown that lifespan was slightly affected by dietary stress. We found that lifespan decreases significantly under thermal stress conditions with increasing altitude. Moreover, there was a slightly negative relationship between altitude and lifespan, which was closely associated with climatic factors such as temperature and precipitation, may suggest local adaptation to climate. PMID- 27712667 TI - Effects of environmental variables on surface temperature of breeding adult female northern elephant seals, Mirounga angustirostris, and pups. AB - Pinnipeds spend extended periods of time on shore during breeding, and some temperate species retreat to the water if exposed to high ambient temperatures. However, female northern elephant seals (Mirounga angustirostris) with pups generally avoid the water, presumably to minimize risks to pups or male harassment. Little is known about how ambient temperature affects thermoregulation of well insulated females while on shore. We used a thermographic camera to measure surface temperature (Ts) of 100 adult female elephant seals and their pups during the breeding season at Point Reyes National Seashore, yielding 782 thermograms. Environmental variables were measured by an onsite weather station. Environmental variables, especially solar radiation and ambient temperature, were the main determinants of mean and maximum Ts of both females and pups. An average of 16% of the visible surface of both females and pups was used as thermal windows to facilitate heat loss and, for pups, this area increased with solar radiation. Thermal window area of females increased with mean Ts until approximately 26 degrees C and then declined. The Ts of both age classes were warmer than ambient temperature and had a large thermal gradient with the environment (female mean 11.2+/-0.2 degrees C; pup mean 14.2+/-0.2 degrees C). This large gradient suggests that circulatory adjustments to bypass blubber layers were sufficient to allow seals to dissipate heat under most environmental conditions. We observed the previously undescribed behavior of females and pups in the water and determined that solar radiation affected this behavior. This may have been possible due to the calm waters at the study site, which reduced the risk of neonates drowning. These results may predict important breeding habitat features for elephant seals as solar radiation and ambient temperatures change in response to changing climate. PMID- 27712668 TI - Keeping it in the family: the impact of marital status and next of kin on cancer treatment and survival. AB - BACKGROUND: This study examines the impact of marriage and next of kin identity on timing of diagnosis, treatment, and survival in cancer patients. METHODS: Retrospective review of patients with 5 solid tumor types treated at an academic medical center from 2002 to 2012. Exposures of interest were marriage status at time of diagnosis and familial relationship with next of kin (NOK). Association with overall survival determined via Cox regressions and with early diagnosis (stage I to II) and receipt of surgery via logistic regressions. RESULTS: Marriage was not associated with early diagnosis for any cancer type. After adjustment, being married was associated with significantly higher odds of receiving surgery only for pancreatic cancer and with improved survival for breast and lung cancers. Having a nuclear relationship with NOK was not associated with any outcomes. CONCLUSIONS: Marriage status was associated with improved outcomes for certain cancers whereas familial relationship with NOK was not.

AB - BACKGROUND: Irreversible electroporation is increasingly used for treatment of solid tumors, but safety data remain scarce. This study aimed to describe intraoperative adverse events associated with irreversible electroporation in patients undergoing solid tumor ablation. METHODS: We analyzed demographic and intraoperative data for patients (n = 43) undergoing irreversible electroporation for hepato-pancreato-biliary and retroperitoneal malignancies (2012 to 2015). Adverse events were defined as cardiac, surgical, or equipment-related. RESULTS: Adverse events (n = 20, 47%) were primarily cardiac (90%, n = 18), including blood pressure elevation (77%, n = 14/18) and arrhythmia (16%, n = 7/43). All but one was managed medically, 1 patient with arrhythmia required termination of ablation. Bleeding and technical problems with the equipment occurred in 1 patient each. Multivariable analysis revealed previous cardiovascular disease and needle placement close to the celiac trunk associated with increased likelihood for cardiac events. CONCLUSIONS: Intraoperative cardiac adverse events are common during irreversible electroporation but rarely impair completion of the procedure. PMID- 27712670 TI - Insecure times? Workers' perceived job and labor market security in 23 OECD countries. AB - By examining the association between employees' perceptions of job security and central labor market policies and characteristics, this paper seeks to understand the mechanisms through which institutions generate confidence and positive expectations among individuals regarding their economic future. The analyses distinguish between different facets of perceived job security and different institutional mechanisms. My multilevel analyses of a data set that contains information on 12,431 individuals and 23 countries show that some labor market policies and characteristics are more likely than others to provide workers with subjective security. Unemployment assistance in particular is an effective means of reducing workers' worries about job loss. Dismissal protection, by contrast, only unleashes its psychologically protective effects under certain conditions. The paper's main conclusion is that the effectiveness of policies varies and that different types of labor market institutions serve as complements rather than as substitutes. PMID- 27712671 TI - The exclusion from welfare benefits: Resentment and survey attrition in a randomized controlled trial in Mexico. AB - Public policy programs must often impose limits on who may be eligible for benefits. Despite research on the impact of exclusion in developed countries, there is little evidence on how people react to being excluded from benefits in developing societies. Utilizing repeated waves of data from an experimental evaluation of Mexico's foundational PROGRESA antipoverty program, we examine the impact of exclusion and distinguish two separate forms. "Statistical exclusion" occurs where determination of benefits is based on randomized assignment to a treatment and control group. "Needs-based exclusion" occurs when benefits programs are designed to be selective rather than universal, basing eligibility on characteristics, like relative poverty, that are difficult to measure simply and accurately. Focusing on temporal variation in survey non-response as our behavioral outcome, we show that needs-based exclusion has much greater negative effects on continued participation than statistical exclusion. We also show that these effects are concentrated among the wealthy, that is, those furthest from the eligibility cut-off line. These findings reinforce general concerns about the validity of evaluation studies when incentives are at work. We discuss both the behavioral explanations that might underlie these findings as well as some potential approaches to reduce threats to evaluation validity. PMID- 27712672 TI - Life satisfaction, ethnicity and neighbourhoods: Is there an effect of neighbourhood ethnic composition on life satisfaction? AB - Immigrants and ethnic minorities tend to have lower life satisfaction than majority populations. However, current understanding of the drivers of these gaps is limited. Using a rich, nationally representative data set with a large sample of ethnic minorities and matched neighbourhood characteristics, we test whether first and second generation minorities experience lower life satisfaction once accounting for compositional differences and whether, specifically, neighbourhood deprivation impacts their wellbeing. We further investigate whether a larger proportion of own ethnic group in the neighbourhood improves satisfaction. We find life satisfaction is lower among ethnic minorities, and especially for the second generation, even controlling for individual and area characteristics. Neighbourhood concentration of own ethnic group is, however, associated with higher life satisfaction for Black Africans and UK born Indians and Pakistanis. The effect for Black Africans may stem from selection into areas, but findings for Indians and Pakistanis are robust to sensitivity tests. PMID- 27712673 TI - How the macroeconomic context impacts on attitudes to immigration: Evidence from within-country variation. AB - This study investigates the effects of the macroeconomic context on attitudes to immigration. Earlier studies do in some cases not provide significant empirical support for the existence of important such effects. In this article it is argued that this lack of consistent evidence is mainly due to the cross-national setup of these studies being vulnerable to estimation bias caused by country-specific factors. The present study instead analyzes attitude variation within countries over time. The results provide firm empirical support in favor of macroeconomic variation importantly affecting attitudes to immigration. As an illustration, the estimates indicate that the number of individuals in the average European country in 2012 who were against all immigration from poorer countries outside Europe was 40% higher than it would have been if macroeconomic conditions in that year had been as good as they were in 2006. PMID- 27712674 TI - Context effects and the temporal stability of stated preferences. AB - In stated preference studies it is assumed that individuals' answers reflect true preferences and are stable over time. We test these two assumptions of validity and reliability using as an example a choice experiment study on ethical consumption that measures preferences for a Peace Product jointly produced by Israeli and Palestinian producers as well as for organic products. In a web survey conducted in Germany, we investigate the validity assumption by manipulating the question context and presenting one group of respondents with questions on anti-Semitic and anti-Arabic attitudes before the choice tasks, and presenting another group with these questions after the choice tasks. In order to test the assumption of temporal stability, the same experimental set-up was repeated in a second survey based on a new sample ten months after the first. However, prior to the second survey an external event, a major violent dispute between Israelis and the Palestinians occurred. Overall, we find evidence for a context effect but not for temporal instability. In both surveys, the placement of the attitudinal questions before the choice tasks has a positive effect on the valuation of products from Israel, Palestinian products and the Peace Product (i.e. a directional context effect). The respondents seem to act according to an anti-discrimination norm. In line with this reasoning, we find an attention shift caused by the attitudinal questions. Organic products are valued much less positively if discriminatory attitudes are surveyed before the choice tasks. Furthermore, despite the violent dispute, stated preferences are very stable over time. This indicates high reliability of stated preference studies and encourages the use of study results by private and public decision makers. PMID- 27712676 TI - The state of domestic affairs: Housework, gender and state-level institutional logics. AB - Multi-level cross-national research consistently shows individual housework arrangements are structured by broader contexts of equality. Across this body of research, the United States is treated as a single entity. Yet, individual-level housework time may vary by state-to-state differences in institutional market, family and legislative logics. To test these relationships, we pair individual level data from the American Time Use Survey (2003-2012; aged 18 to 64 n = 106,190) with three state-level indices - female labor force empowerment, family traditionalism and state government liberalism. For market institutional logics, we find wives and husbands spend more but mothers less time in housework in states where women have more labor market power. For family logics, we find mothers spend more and husbands less time in housework in more traditional states. For legislative logics, we find women and husbands spend more time in housework in more liberal states. Our results highlight the importance of state to-state institutional logics on individuals' housework time. PMID- 27712675 TI - Does higher education expansion promote educational homogamy? Evidence from married couples of the post-80s generation in Shanghai, China. AB - The expansion of higher education witnessed in many societies influences the pattern of educational assortative mating. Structural transition theory predicts growing educational homogamy due to increasing preference for highly-educated partners who become more widely available. In contrast, social closure theory suggests depressed educational homogamy because the inflation of the education elite circle fosters the openness of marriage market, reducing the preference for a highly-educated mate and increasing the penetrability across social-status boundaries. Capitalizing the survey data that are representative of the post-80s one-child generation collected in Shanghai, China, we test the hypotheses derived from the two theories. Empirical results suggest that, with increasing availability of highly educated individuals, the extent of educational homogamy by birth cohort reveals a U-shaped pattern. This U-shaped pattern demonstrates increasing levels of educational homogamy and lends support to structural transition theory. PMID- 27712677 TI - It takes two: A dyadic model of recruitment to civic activity. AB - Why are some people, but not others, asked to engage in civic activity? Rather than focus on the personal traits of either potential recruits or recruiters for this initial stage of recruitment, we develop and test a theoretical framework that emphasizes the importance of shared relationships and characteristics between those doing the recruiting and those being recruited. Specifically, the nature of interactions, overlapping community and associational space, status and value homophily, and strength and intimacy are assessed to explain differential recruitment among people's closest ties. Furthermore, unlike previous studies, we do so across three different forms of civic activity-blood donation, volunteer work, and political activism-allowing us to identify larger patterns in civic solicitation. Results from multilevel analyses of dyads reorganized from ego centric data of U.S. adults show that while certain personal traits of egos and alters remain significant, attributes of the dyad are equally, if not more, consequential for explaining variation in who gets asked to participate in civic activity. Importantly, while certain dyadic characteristics-such as romantic partnerships-promote recruitment to all three forms of civic activity, the effects of others-such as sex homophily-are unique to specific forms. Broadly speaking, our results indicate that some types of dyadic characteristics are more powerful than others and that there are important differences in how particular dimensions of social connections shape recruitment efforts across the specific activities of donating blood, volunteering time, and engaging in political activism. PMID- 27712678 TI - Donations and dependence: Individual contributor strategies in house elections. AB - Despite the importance of individual contributors to financing federal candidates, past work has largely neglected this crucial financial constituency in favor of research on corporate and trade political action committees (PACs). By contrast, in this study I offer the first analysis of aggregate contributions from the population of individual contributors to House candidates. Using an original big dataset constructed from over fifteen million Federal Election Commission (FEC) disclosure records, I identify individual contributors (rather than contributions) and trace the variation in their strategies across types of House candidates. I distinguish between frequent donors, who are theorized to have more contact with members of Congress, versus infrequent donors in these elections. I find evidence that the character of aggregate donations from repeat donors is more access-oriented even while controlling for other salient candidate characteristics. Funds from infrequent donors, in contrast, appear more ideologically motivated. By also examining the percentage of funds that House candidates receive from repeat donors, I show that the fundraising coalitions of candidates may reproduce reliance on more access-oriented, repeat donors despite the influx of dollars from infrequent donors. I suggest that my findings provide a persuasive case for re-evaluating the diversity of roles individual contributors play in the campaign finance system, and for systematically analyzing variation in contributor strategies. PMID- 27712679 TI - Socially organized sentiments: Exploring the link between religious density and protest mobilization, 1960-1995. AB - Extensive research has shown individual religiosity to have an impact upon U.S. protest participation. But very little work has examined the role of religious density in a community on the likelihood of protest mobilization. Our research links the religious density across 62 counties in New York State to various protest mobilization issues during the period of 1960-1995. In this research, we develop a theory of socially organized sentiments to examine religious influences on overall protest event mobilizations in local communities, a specific example of a more general theory that can link community structure to multiple forms of civic engagement. The impact of various religious traditions is assessed by using measures for the density of religious population per congregation of three religious traditions-Mainline Protestantism, Evangelical Protestantism and Catholicism. The analysis also assesses the likelihood of mobilization concerning four specific issues-African-American civil rights, gender, anti-nuclear/peace, and anti-poverty movements. PMID- 27712680 TI - Does the standard voluntary association question capture informal associations? AB - Sociologists have long been attentive to participation in associational life. Yet, despite being repeatedly cautioned to consider more informal groups, most researchers focus on participation in formal voluntary associations using national surveys with fixed group categories, such as the General Social Survey (GSS). In this paper, we use new GSS data on the names of the voluntary associations listed by respondents to evaluate whether voluntary association prompts capture or miss various types of informal associations. We code the formality of the associations listed by respondents and also compare to a new sample of bottom-up, informal voluntary associations. We demonstrate that some response categories adequately capture both formal and informal associations, e.g., sports groups. However, our results also suggest that the standard voluntary association question both omits entire categories of informal associations and omits some informal variants of associations within categories. In the tradition of Baumgartner and Walker (1988), Wuthnow (1994), and Wellman et al. (2001), we suggest that we may misunderstand citizen associations if we ignore informal associating. PMID- 27712681 TI - Risky sexual behavior of foreign and native-born women in emerging adulthood: The long reach of mother-daughter relationships in adolescence. AB - Parents' influence on young adult sexual behavior receives little attention compared to influence on adolescent behavior. Yet effective parenting should have lasting effects. Even fewer studies examine parents' influence on sexual behavior of both foreign and native-born young adults. Using the National Longitudinal Study of Adolescent to Adult Health (Add Health) Waves I (1994-95) and III (2001 02), we examine longitudinal associations among mother-daughter relationship quality and nativity during adolescence and young adults' risky sexual behaviors of condom use at last intercourse, number of sexual partners, and STI diagnoses (N = 4460). Women, 18-26 years old, who had good mother-adolescent daughter relationships have fewer partners and STIs in the past year. Second generation women have worse mother-adolescent daughter relationships, compared to third generation. Relationship quality does not explain associations between nativity and risky behavior. Lasting associations between relationship quality and risk behaviors suggest that reproductive health interventions should enhance mother adolescent relationships. PMID- 27712682 TI - Home sweet home? Home physical environment and inflammation in children. AB - The home environment includes important social and physical contexts within which children develop. Poor physical home environments may be a potential source of stress for children through difficult daily experiences. Using a sub-sample from the Los Angeles Family and Neighborhood Survey (N = 425), we consider how the home physical environment affects stress-related immune system dysregulation in children ages 3-18 years. Results indicated that children in poorer quality homes had higher inflammation (measured by C-reactive protein). The associations were particularly strong for younger children. We also found that part of the home physical environment association with CRP worked through increased risk of obesity for children living in low-quality homes. Future research should assess how home physical environments could be improved to reduce stress and improve health outcomes in children. PMID- 27712683 TI - Child support and mixed-status families an analysis using the Fragile Families and Child Wellbeing Study. AB - A large body of literature documents the importance of child support for children's wellbeing, though little is known about the child support behaviors of mixed-status families, a large and rapidly growing population in the United States. In this paper, we use data from the Fragile Families and Child Wellbeing Study to investigate the impact of citizenship status on formal and informal child support transfers among a nationally representative sample of parents who have citizen children. Probit regression models and propensity score matching (PSM) estimators show that mixed-status families are significantly less likely to have child support orders and child support receipt compared to their citizen counterparts. We found that mothers' knowledge of the child support system increases the probability of establishing paternity. However, cultural differences in knowledge of and perception about the U.S. child support system between mixed-status families and citizen families do not have an impact on the probability of getting a child support order, child support receipt, or in-kind child support. Rather, institutional factors such as collaborations between welfare agencies and child support enforcement agencies as well as state child support enforcement efforts have a significant impact on formal child support outcomes. The results are robust against different model specifications, measure constructions, and use of datasets. These findings have important policy implications for policy makers and researchers interested in reducing child poverty in complex family structures and underscore the need to revisit child support policies for mixed-status families. PMID- 27712684 TI - Tethered lives: A couple-based perspective on the consequences of parenthood for time use, occupation, and wages. AB - Prior research on parenthood effects has typically used single-sex models and estimated average effects. By contrast, we estimate population-level variability in partners' changes in housework hours, paid work hours, occupation traits, and wages after becoming parents, and we explore whether one partner's adjustment offsets or supplements the other's. We find tradeoffs between spouses on paid work adjustments to parenthood, but complementarity in adjustments to housework hours, occupation traits, and wages. The effect of parenthood on wives' behaviors is larger and more variable than on husbands' behaviors in every domain. The modest variation between husbands in work responses to parenthood explains little of the variation in the motherhood penalty, while variation in wives' own behaviors plays a larger role. We refer to this pattern as tethered autonomy: variation across American couples in work responses to parenthood is shaped primarily by variation in wives' adjustments, while husbands' work acts largely as a fixed point. PMID- 27712686 TI - Displacement in new economy labor markets: Post-displacement wage loss in high tech versus low tech cities. AB - While scholars and politicians tout education as the salve to employment disruptions, we argue that the geography of the new economy, and the social closure mechanisms that geography creates, may be just as important as individuals' characteristics for predicting post-displacement wage loss (or gain). We use data from the 2012 Displaced Workers ement of the Current Population Survey and from the 2010 United States Census to test hypotheses linking local labor markets in different industrial contexts to post-displacement wage loss. Our results point to age as a closure mechanism, and to the partially protective effect of education in high-tech versus low-tech economic sectors. This study is the first to use national level data to examine how employment in high-tech cities influences post-displacement wages. These findings are relevant both for theorizing about the new economy and for public policy. PMID- 27712685 TI - Factors associated with two types of child custody loss among a sample of African American mothers: A novel approach. AB - African American families are overrepresented in the Child Welfare System; however, extant research on this phenomenon has (1) focused mostly on Caucasian or mixed-race samples and (2) has not examined informal custody arrangements alongside official child custody loss. This research addresses these gaps in the literature by examining factors associated with both official and informal child custody loss among a sample of African American mothers. Multinomial regression results show that having ever been incarcerated following a conviction increases the odds of experiencing both types of custody loss relative to no loss. Additionally, mother's experiences of childhood victimization increase the likelihood of informal custody loss relative to no loss, while being older, past year homelessness, number of minor children, being lesbian or bisexual, crack/cocaine use, and more family social support increase the odds of official loss versus no loss. Finally, increases in social support from friends decrease the odds of official loss. Implications are discussed. PMID- 27712688 TI - Segregation by race and income in the United States 1970-2010. AB - A systematic analysis of residential segregation and spatial interaction by income reveals that as income rises, minority access to integrated neighborhoods, higher levels of interaction with whites, and more affluent neighbors also increase. However, the income payoffs are much lower for African Americans than other groups, especially Asians. Although Hispanics and Asians have always displayed declining levels of minority-white dissimilarity and rising levels of minority-white interaction with rising income, income differentials on these outcomes for blacks did not appear until 1990 and since then have improved at a very slow pace. Given their higher overall levels of segregation and income's limited effect on residential attainment, African Americans experience less integration, more neighborhood poverty at all levels of income compared to other minority groups. The degree of black spatial disadvantage is especially acute in the nation's 21 hypersegregated metropolitan areas.

PMID- 27712690 TI - Altering the life course: Military service and contact with the criminal justice system. AB - Using data taken from the 1997 National Longitudinal Survey of Youth, we examine the relationship between military service and contact with the criminal justice system. Drawing on the life course concept of a turning point, we show that military service does little to affect the risk of being arrested or being convicted of crimes involving violence or destructive behavior, while at the same time significantly reducing the risk of being arrested or being convicted of non violent crimes. We find no evidence that service in a combat zone alters these relationships. Our results demonstrate how participation in a large-scale institution can serve as a turning point, altering the life course trajectories of young persons. PMID- 27712687 TI - Risk factors and outcomes of chronic sexual harassment during the transition to college: Examination of a two-part growth mixture model. AB - A two-part latent growth mixture model was implemented in order to examine heterogeneity in the growth of sexual harassment (SH) victimization in college and university students, and the extent to which SH class membership explains substance use and mental health outcomes for certain groups of students. Demographic risk factors, mental health, and substance use were examined as they related to chronically experienced SH victimization. Incoming freshmen students (N = 2855; 58% female; 54% White) completed a survey at five time points. In addition to self-reporting gender, race, and sexual orientation, students completed measures of sexual harassment, anxiety, depression, binge drinking, and marijuana use. Overall, self-reported SH declined upon college entry, although levels rebounded by the third year of college. Results also supported a two-class solution (Infrequent and Chronic) for SH victimization. Being female, White, and a sexual minority were linked to being classified into the Chronic (relative to the Infrequent) SH class. In turn, Chronic SH class membership predicted greater anxiety, depression, and substance use, supporting a mediational model. PMID- 27712691 TI - Reversing welfare reform? Immigrant restoration efforts and food stamp receipt among Mexican immigrant families. AB - The safety net that immigrants face today differs significantly from the immediate post-Welfare Reform era in terms of eligibility and economic context. To inform debates on immigrant access to the safety net, this paper examines implications of the 2002 Farm Security and Rural Investment Act, which restored food stamp eligibility to nearly two-thirds of immigrants who lost eligibility under Welfare Reform. Using data from the 1995-2013 Current Population Survey and a difference-in-difference design, I examine how restoration efforts have influenced food stamp participation and food insecurity rates among low-income Mexican immigrant households with children. I then examine trends in food stamp receipt across policy and economic changes since Welfare Reform. Overall, results suggest that immigrant restoration efforts have reversed some but not all of the negative consequences of Welfare Reform and that immigrant households' use of food stamps has increased, particularly in the wake of the Great Recession.

PMID- 27712695 TI - Estimating Health-State Utility for Economic Models in Clinical Studies: An ISPOR Good Research Practices Task Force Report. AB - Cost-utility models are increasingly used in many countries to establish whether the cost of a new intervention can be justified in terms of health benefits. Health-state utility (HSU) estimates (the preference for a given state of health on a cardinal scale where 0 represents dead and 1 represents full health) are typically among the most important and uncertain data inputs in cost-utility models. Clinical trials represent an important opportunity for the collection of health-utility data. However, trials designed primarily to evaluate efficacy and safety often present challenges to the optimal collection of HSU estimates for economic models. Careful planning is needed to determine which of the HSU estimates may be measured in planned trials; to establish the optimal methodology; and to plan any additional studies needed. This report aimed to provide a framework for researchers to plan the collection of health-utility data in clinical studies to provide high-quality HSU estimates for economic modeling. Recommendations are made for early planning of health-utility data collection within a research and development program; design of health-utility data collection during protocol development for a planned clinical trial; design of prospective and cross-sectional observational studies and alternative study types; and statistical analyses and reporting. PMID- 27712696 TI - When Future Change Matters: Modeling Future Price and Diffusion in Health Technology Assessments of Medical Devices. AB - BACKGROUND: Health technology assessments (HTAs) that take account of future price changes have been examined in the literature, but the important issue of price reductions that are generated by the reimbursement decision has been ignored. OBJECTIVES: To explore the impact of future price reductions caused by increasing uptake on HTAs and decision making for medical devices. METHODS: We demonstrate the use of a two-stage modeling approach to derive estimates of technology price as a consequence of changes in technology uptake over future periods on the basis of existing theory and supported by empirical studies. We explore the impact on cost-effectiveness and expected value of information analysis in an illustrative example on the basis of a technology in development for preterm birth screening. RESULTS: The application of our approach to the case study technology generates smaller incremental cost-effectiveness ratios compared with the commonly used single cohort approach. The extent of this reduction in the incremental cost-effectiveness ratio depends on the magnitude of the modeled price reduction, the speed of diffusion, and the length of the assumed technology life horizon. Results of value of information analysis are affected through changes in the expected net benefit calculation, the addition of uncertain parameters, and the diffusion-adjusted estimate of the affected patient population. CONCLUSIONS: Because modeling future changes in price and uptake has the potential to affect HTA outcomes, modeling techniques that can address such changes should be considered for medical devices that may otherwise be rejected. PMID- 27712697 TI - International Experiences in Quantitative Benefit-Risk Analysis to Support Regulatory Decisions. PMID- 27712699 TI - Patient-Focused Benefit-Risk Analysis to Inform Regulatory Decisions: The European Union Perspective. AB - Regulatory decisions are often based on multiple clinical end points, but the perspectives used to judge the relative importance of those end points are predominantly those of expert decision makers rather than of the patient. However, there is a growing awareness that active patient and public participation can improve decision making, increase acceptance of decisions, and improve adherence to treatments. The assessment of risk versus benefit requires not only information on clinical outcomes but also value judgments about which outcomes are important and whether the potential benefits outweigh the harms. There are a number of mechanisms for capturing the input of patients, and regulatory bodies within the European Union are participating in several initiatives. These can include patients directly participating in the regulatory decision-making process or using information derived from patients in empirical studies as part of the evidence considered. One promising method that is being explored is the elicitation of "patient preferences." Preferences, in this context, refer to the individual's evaluation of health outcomes and can be understood as statements regarding the relative desirability of a range of treatment options, treatment characteristics, and health states. Several methods for preference measurement have been proposed, and pilot studies have been undertaken to use patient preference information in regulatory decision making. This article describes how preferences are currently being considered in the benefit-risk assessment context, and shows how different methods of preference elicitation are used to support decision making within the European context. PMID- 27712698 TI - Regulatory Decision Making in Canada-Exploring New Frontiers in Patient Involvement. AB - Recent legislative amendments aim to enhance the transparency of the regulatory review processes about drugs, and provide public information about Health Canada's review decisions. There is also growing recognition of the value, with respect to regulatory benefit-risk assessment, of information that could be gathered from patients-the direct users of these products. Patients can provide unique insights into practical aspects of living with their disease and its treatments-as well as gaps in treatment needs. An enhanced understanding of patients' experiences and perspectives can contribute directly to better-informed decision making about these products by regulators. Health Canada is currently exploring and examining the most effective ways to collect and consider patient input in the evaluation of therapeutic products. As part of this process, Health Canada is assessing the suitability of other existing models through environmental scans, discussions with other health authorities, and pilot projects. Lessons learned from these models can inform best practices and opportunities for patient involvement when designing a model to meet Canada's needs and context. Health Canada launched a Patient Involvement Pilot Project in 2014 to simulate how input from patients, their caregivers, health care professionals, and patient groups could be collected and incorporated in the drug submission review process. This ongoing experience and continuous learning will define better how to incorporate patient input into benefit-risk assessment and regulatory decision making throughout the life cycle of therapeutic products in Canada. PMID- 27712700 TI - Patient Preferences in Regulatory Benefit-Risk Assessments: A US Perspective. AB - Demands for greater transparency in US regulatory assessments of benefits and risks, together with growing interest in engaging patients in Food and Drug Administration regulatory decision making, have resulted in several recent regulatory developments. Although Food and Drug Administration's Center for Drug Evaluation and Research (CDER) and Center for Devices and Radiological Health (CDRH) have established patient-engagement initiatives, CDRH has proposed guidelines for considering quantitative data on patients' benefit-risk perspectives, while CDER has focused on a more qualitative approach. We summarize two significant studies that were developed in collaboration and consultation with CDER and CDRH. CDER encouraged a patient advocacy group to propose draft guidance on engaging patient and caregiver stakeholders in regulatory decision making for Duchenne muscular dystrophy. CDRH sponsored a discrete-choice experiment case study to quantify obese respondents' perspectives on "meaningful benefits." CDRH and CDER issued draft guidance in May and June 2015, respectively, on including patient-preference data in regulatory submissions. Both organizations face challenges. CDER is working on integrating qualitative data into existing evidence-based review processes and is exploring options for therapeutic areas not included on a priority list. CDRH has adopted an approach that requires patient-preference data to satisfy standards of valid scientific evidence. Although that strategy could facilitate integrating patient perspectives directly with clinical data on benefits and harms, generating such data requires building capacity. PMID- 27712701 TI - A Framework for Incorporating Patient Preferences Regarding Benefits and Risks into Regulatory Assessment of Medical Technologies. AB - BACKGROUND: In response to 2012 guidance in which the US Food and Drug Administration's (FDA) Center for Devices and Radiological Health (CDRH) stated the importance of patient-centric measures in regulatory benefit-risk assessments, the Medical Device Innovation Consortium (MDIC) initiated a project. The project was used to develop a framework to help the Food and Drug Administration (FDA) and industry sponsors understand how patient preferences regarding benefit and risk might be integrated into the review of innovative medical devices. METHODS: A public-private partnership of experts from medical device industry, government, academia and non-profits collaborated on development of the MDIC patient centered benefit-risk framework. RESULTS: The MDIC Framework examines what patient preference information is and the potential use and value of patient preference information in the regulatory process and across the product development life cycle. The MDIC Framework also includes a catalog of patient preference assessment methods and an agenda for future research to advance the field. CONCLUSIONS: This article discusses key concepts in patient preference assessment of particular importance for regulators and researchers that are addressed in the MDIC Framework for patient centered benefit-risk assessment as well as the unique public-private collaboration that led its development. PMID- 27712702 TI - Developing a Patient-Centered Benefit-Risk Survey: A Community-Engaged Process. AB - OBJECTIVES: To provide a community-engaged process to inform the design of a stated-preferences experiment. The process involved integrating patients and caregivers of people with Duchenne/Becker muscular dystrophy, advocates, clinicians, and the sponsor in conceptualizing and developing a benefit-risk survey on the basis of phase III trial results. METHODS: Our community-engagement process for the development of a stated-preference survey included a set of five guiding principles with a foundation in the principles of community-engaged research. Engagement efforts were carried out through an informal network of three committees. Members of the leadership, stakeholder, and review committees comprised patients, caregivers, clinicians, advocacy leadership, and industry representatives. RESULTS: Committee members participated in 15 hours of formal engagement including interviews and conference calls that ranged from 45 to 90 minutes, plus additional less-formal ad hoc communication. Committees comprised 20 individuals across three committees including adults with DMD (n = 6), parents of children with DMD (n = 6), clinicians (n = 3), members of research and advocacy organizations (n = 4), and an industry representative (n = 1). Community engagement informed attribute selection, survey length, word choice, and eligibility criteria. Challenges in the process included managing diverse stakeholder perspectives, time requirements, and the inherent tension between outcomes used in clinical trials versus attributes that correspond to patient- and family-relevant outcomes. CONCLUSIONS: We demonstrated how community engagement can successfully influence study design to support the design of a relevant survey instrument that is ethical, acceptable, meaningful to the community, and enhances patient-centered benefit-risk assessment for regulatory decision making. PMID- 27712703 TI - Attribute Development Using Continuous Stakeholder Engagement to Prioritize Treatment Decisions: A Framework for Patient-Centered Research. AB - OBJECTIVES: To develop a methodological approach for selecting, validating, and prioritizing attributes for health care decision making. METHODS: Participants (n = 48) were recruited from community support groups if they had a child aged 26 years or younger diagnosed with a coexisting mental health condition and cognitive impairment. Six in-depth interviews eliciting care management experiences were transcribed and coded into themes following the principles of grounded theory and the constant comparative method. Six focus groups involving 42 participants assessed the relevance, priority, and meaning and inter relationship among the themes. The positive predictive value and sensitivity assessed agreement on thematic meaning. A final list was selected from the top priorities with good agreement as candidate attributes. Attribute levels reflecting the range of experiences in care management decisions emerged from the verbatim passages within each coded theme. RESULTS: Participants were the child's mother (73%), white (77%), married (69%), and on average 48 years old. The children were on average 14 years old; 44% had an intellectual disability, 25% had autism, and more than half had anxiety or attention-deficit/hyperactivity disorder. All 14 attributes identified from the in-depth interviews were deemed relevant. The positive predictive value exceeded 90%, and the sensitivity ranged from 64% to 89%. The final set of attributes formed the framework for care management decisions consisting of six attributes (medication, behavior, services, social, treatment effects, and school) each with three levels. CONCLUSIONS: A systematic approach grounded in qualitative methods produced a framework of relevant, important, and actionable attributes representing competing alternatives in clinical decisions. PMID- 27712704 TI - Measuring High-Risk Patients' Preferences for Pharmacogenetic Testing to Reduce Severe Adverse Drug Reaction: A Discrete Choice Experiment. AB - OBJECTIVES: To investigate patient preferences and willingness to pay (WTP) for a genetic test that can reduce the risk of life-threatening adverse drug reactions (ADRs). We hypothesize that test features (risk of developing the adverse reaction with and without testing, test cost, and treatment cost) and the choice context (physician recommendation and the most common choice made by peer patients) will influence choices. METHODS: A discrete choice experiment was conducted in which 189 patients at high risk for gout were asked to choose between treatment options that varied along key attributes. A latent class logit model was used to analyze the choice data and test the hypotheses. RESULTS: We identified two classes of patients: the risk-averse class and the cost-conscious class. The WTP to reduce the risk of life-threatening ADRs from 1 out of 600 to 1 out of 1 million was SGD1215 in the risk-averse class. In contrast, in the cost conscious class, the WTP was insensitive to the extent of risk reduction. Overall, the predicted take-up rate for the test is 65% at a price of SGD400. If the test was recommended by a physician or was chosen by most of the patients, the take-up rate for the test would increase by 8.5 and 1.5 percentage points, respectively. CONCLUSIONS: There is a potentially large demand for genetic tests that could reduce the risk of life-threatening ADRs. Physician recommendations and providing information on the choices of others are powerful influences on demand, even more so than moderate price reductions. PMID- 27712705 TI - First and Foremost Battle the Virus: Eliciting Patient Preferences in Antiviral Therapy for Hepatitis C Using a Discrete Choice Experiment. AB - BACKGROUND: There has been tremendous progress regarding treatment options for hepatitis C virus (HCV) infection. Several interferon-free regimens are awaiting regulatory approval. These innovations promise substantial reductions in the burden of disease and side effects as well as a decrease in treatment duration. OBJECTIVES: The aim of this quantitaitive study was to elicit patient preferences for attributes of innovative antiviral therapies for hepatitis C. METHODS: A systematic literature search and 14 semi-structured interviews were performed, resulting in eight patient-relevant characteristics. For the discrete choice experiment, an experimental design (3*3 + 5*6) was generated using Ngene software. The survey was conducted in August 2014 through computer-assisted personal interviews. The data were effects-coded in a random parameter logit estimation. RESULTS: Participants were patients with HCV (N = 561; 58.1% men) in different treatment states. The analysis revealed a predominance of the attribute "reaching sustained virological response." When considering confidence intervals, the results showed three different preference ranks. At first place was "sustained virological response" (level difference [LD] 3.98), second was "anemia" (LD 1.10), followed by "number of interferon injections" (LD 0.92), "rash" (LD 0.82), "nausea and/or diarrhea" (LD 0.79), and "duration of antiviral therapy" (LD 0.78). The last position was occupied by both "tiredness/fatigue" (LD 0.31) and "headache" (LD 0.34). CONCLUSIONS: From the patients' point of view, sustained virological response is the most essential criterion for choosing an HCV therapy. It was ranked at the highest, dominating all side effects and modes of administration. Furthermore, this study proved that patients consider both the probability of occurrence and the severity of treatment-induced side effects. Results clearly point to valuation of probabilities that is separate from that of severity. PMID- 27712707 TI - The Capability Approach: A Critical Review of Its Application in Health Economics. AB - The capability approach is an approach to assessing well-being developed by Amartya Sen. Interest in this approach has resulted in several attempts to develop questionnaires to measure and value capability at an individual level in health economics. This commentary critically reviews the ability of these questionnaires to measure and value capability. It is argued that the method used in the questionnaires to measure capability will result in a capability set that is an inaccurate description of the individual's true capability set. The measured capability set will either represent only one combination and ignore the value of choice in the capability set, or represent one combination that is not actually achievable by the individual. In addition, existing methods of valuing capability may be inadequate because they do not consider that capability is a set. It may be practically more feasible to measure and value capability approximately rather than directly. Suggestions are made on how to measure and value an approximation to capability, but further research is required to implement the suggestions. PMID- 27712706 TI - Impact of Treatment Subsidies and Cash Payouts on Treatment Choices at the End of Life. AB - OBJECTIVES: To examine the extent to which financial assistance, in the form of subsidies for life-extending treatments (LETs) or cash payouts, distorts the demand for end-of-life treatments. METHODS: A discrete choice experiment was administered to 290 patients with cancer in Singapore to elicit preferences for LETs and only palliative care (PC). Responses were fitted to a latent class conditional logistic regression model. We also quantified patients' willingness to pay to avoid and willingness to accept a less effective LET or PC-only. We then simulated the effects of various LET subsidy and cash payout policies on treatment choices. RESULTS: We identified three classes of patients according to their preferences. The first class (26.1% of the sample) had a strong preference for PC and were willing to give up life expectancy gains and even pay for receiving only PC. The second class (29.8% of the sample) had a strong preference for LETs and preferred to extend life regardless of cost or quality of life. The final class (44.1% of the sample) preferred LETs to PC, but actively traded off costs and length and quality of life when making end-of-life treatment choices. Policy simulations showed that LET subsidies increase demand for LETs at the expense of demand for PC, but an equivalent cash payout was not shown to distort demand. CONCLUSIONS: Patients with cancer have heterogeneous end-of-life preferences. LET subsidies and cash payouts have differing effects on the use of LETs. Policymakers should be mindful of these differences when designing health care financing schemes for patients with life-limiting illnesses. PMID- 27712708 TI - Patient Heterogeneity in Health Economic Decision Models for Chronic Obstructive Pulmonary Disease: Are Current Models Suitable to Evaluate Personalized Medicine? AB - OBJECTIVES: To assess how suitable current chronic obstructive pulmonary disease (COPD) cost-effectiveness models are to evaluate personalized treatment options for COPD by exploring the type of heterogeneity included in current models and by validating outcomes for subgroups of patients. METHODS: A consortium of COPD modeling groups completed three tasks. First, they reported all patient characteristics included in the model and provided the level of detail in which the input parameters were specified. Second, groups simulated disease progression, mortality, quality-adjusted life-years (QALYs), and costs for hypothetical subgroups of patients that differed in terms of sex, age, smoking status, and lung function (forced expiratory volume in 1 second [FEV1] % predicted). Finally, model outcomes for exacerbations and mortality for subgroups of patients were validated against published subgroup results of two large COPD trials. RESULTS: Nine COPD modeling groups participated. Most models included sex (seven), age (nine), smoking status (six), and FEV1% predicted (nine), mainly to specify disease progression and mortality. Trial results showed higher exacerbation rates for women (found in one model), higher mortality rates for men (two models), lower mortality for younger patients (four models), and higher exacerbation and mortality rates in patients with severe COPD (four models). CONCLUSIONS: Most currently available COPD cost-effectiveness models are able to evaluate the cost-effectiveness of personalized treatment on the basis of sex, age, smoking, and FEV1% predicted. Treatment in COPD is, however, more likely to be personalized on the basis of clinical parameters. Two models include several clinical patient characteristics and are therefore most suitable to evaluate personalized treatment, although some important clinical parameters are still missing. PMID- 27712709 TI - Cost-Effectiveness of Rotavirus Vaccination in France-Accounting for Indirect Protection. AB - BACKGROUND: Vaccination against rotavirus has shown great potential for reducing the primary cause of severe childhood gastroenteritis. Previous economic evaluations of rotavirus vaccination in France have not modeled the potential impact of vaccines on disease burden via reduced transmission. OBJECTIVE: To determine the cost-effectiveness of the introduction of pentavalent rotavirus vaccination into the French infant vaccination schedule. METHODS: We developed an age-structured model of rotavirus transmission calibrated to 6 years of French gastroenteritis incidence and vaccine clinical trial data. We evaluated the cost effectiveness of pentavalent rotavirus vaccination considering that 75% of infants would receive the three-dose vaccine course. RESULTS: Our model predicts that rotavirus vaccination will decrease rotavirus gastroenteritis incidence and associated clinical outcomes in vaccinated and unvaccinated individuals, delay the seasonal peak of infection, and increase the age of infection. From the societal perspective, our base-case scenario predicts that vaccination coverage would be cost-effective at ?115 or ?135 per vaccine course at ?28,500 and ?39,500/quality-adjusted life-year (QALY) gained, respectively, and suggests that almost 95% of the financial benefits will be recouped within the first 5 years following vaccination implementation. From the third-party payer perspective, incremental cost-effectiveness ratios ranged from ?12,500 to ?20,000/QALY, respectively. Our uncertainty analysis suggests that findings were sensitive to various assumptions including the number of hospitalizations, outpatient visits, and the extent of QALY losses per rotavirus episode. CONCLUSIONS: Introducing pentavalent rotavirus vaccination into the French infant vaccination schedule would significantly reduce the burden of rotavirus disease in children, and could be cost-effective under plausible conditions. PMID- 27712710 TI - Measuring Health and Broader Well-Being Benefits in the Context of Opiate Dependence: The Psychometric Performance of the ICECAP-A and the EQ-5D-5L. AB - BACKGROUND: Measuring outcomes in economic evaluations of social care interventions is challenging because both health and well-being benefits are evident. The ICEpop CAPability instrument for adults (ICECAP-A) and the five level EuroQol five-dimensional questionnaire (EQ-5D-5L) are measures potentially suitable for the economic evaluation of treatments for substance use disorders. Evidence for their validity in this context is, however, lacking. OBJECTIVES: To assess the construct validity of the ICECAP-A and the EQ-5D-5L in terms of convergent and discriminative validity and sensitivity to change on the basis of standard clinical measures (Clinical Outcomes in Routine Evaluation-Outcome Measure, Treatment Outcomes Profile, Interpersonal Support Evaluation List, Leeds Dependence Questionnaire, and Social Satisfaction Questionnaire). METHODS: A secondary analysis of pilot trial data for heroin users in opiate substitution treatment was conducted. Baseline convergence with clinical measures was assessed using the Pearson correlation coefficient. Discriminative validity was assessed using one-way analysis of variance and stepwise regressions. Sensitivity to changes in clinical indicators was assessed at 3 and 12 months using the standardized response mean statistic and parametric and nonparametric testing. RESULTS: Both measures had the same level of construct validity, except for clinical indicators of well-being, for which the ICECAP-A performed better. The ICECAP-A was sensitive to changes in both health and well-being indicators. The EQ-5D-5L had lower levels of sensitivity to change, and a ceiling effect (27%), particularly evident in the dimensions of self-care (89%), mobility (75%), and usual activities (72%). CONCLUSIONS: The findings support the construct validity of both measures, but the ICECAP-A gives more attention to broader impacts and is more sensitive to change. The ICECAP-A shows promise in evaluating treatments for substance use disorders for which recovery is the desired outcome. PMID- 27712711 TI - Comparison of Daily versus Weekly Recording of Gastroesophageal Reflux Disease Symptoms in Patients with a Partial Response to Proton Pump Inhibitor Therapy. AB - BACKGROUND: The Reflux Symptom Questionnaire electronic Diary (RESQ-eD) and the Reflux Symptom Questionnaire 7-day recall (RESQ-7) are versions of a patient reported outcome instrument that was developed and validated for measuring the frequency and intensity of symptoms in patients with gastroesophageal reflux disease (GERD) who have a partial response to proton pump inhibitor (PPI) therapy. OBJECTIVE: The aim of these analyses was to assess the ability of the RESQ-7 to reproduce findings based on RESQ-eD reports of the same symptoms. METHODS: These analyses are based on data from patients with GERD with a partial response to PPI (ClinicalTrials.gov identifier: NCT00703534). Participants completed the RESQ-eD twice daily for 7 days and the RESQ-7 on day 7. RESULTS: Data from 446 patients were available for these analyses. Symptom-level analyses showed that, for intensity, mean domain scores were higher for the RESQ-7 (range 1.49-2.72) than for the RESQ-eD (range 1.45-2.57); for frequency, scores were lower for the RESQ-7 (range 2.58-4.82) than for the RESQ-eD (range 4.22-6.24). Correspondence analyses of RESQ-7 and RESQ-eD mean domain scores indicated excellent agreement for intensity (correlation-concordance coefficient 0.77-0.83) and fair agreement for frequency (correlation-concordance coefficient 0.40-0.58). Mean RESQ-eD subscale intensity scores for GERD symptoms were higher for symptoms experienced during the daytime than for those occurring at nighttime. Symptom recall was not associated with peak or recency effects. CONCLUSIONS: Patients with GERD slightly overestimated the intensity of their reflux symptoms and markedly underestimated the frequency on weekly recall compared with twice-daily reporting. PMID- 27712712 TI - Which Questionnaire Should Be Used to Measure Quality-of-Life Utilities in Patients with Acute Leukemia? An Evaluation of the Validity and Interpretability of the EQ-5D-5L and Preference-Based Questionnaires Derived from the EORTC QLQ C30. AB - OBJECTIVES: The aim of this study was to assess the validity and interpretability of different preference-based questionnaires (generic 5-level EuroQol five dimensional questionnaire [EQ-5D-5L], cancer-specific Quality of Life Questionnaire Preference-Based Measure, and European Organization of Randomized Controlled Trials 8 Dimension [EORTC-8D]) in patients with acute leukemia. METHODS: Patients who participated in Hemato-Oncologie voor Volwassenen Nederland (HOVON - the Haemato Oncology Foundation for Adults in the Netherlands) clinical trials between 1999 and 2011 at a single hospital were invited to complete the questionnaires. Interpretability was evaluated by the frequency of incomplete data and highest and lowest possible scores. Content validity was evaluated by exploring the health-related quality-of-life domains included in the questionnaires. Construct validity was assessed using correlations with other quality-of-life scales (EQ-visual analogue scale score and global quality-of-life scale of the EORTC Quality of Life Questionnaire) and ability to distinguish between patients with different health statuses. RESULTS: Questionnaires were returned by 89% (111 of 125) of the patients. Six to seven respondents did not return full questionnaires. Perfect health on the EQ-5D-5L was reported by 32 respondents and many of them (N = 17) did report health problems on other questionnaires. All questionnaires were strongly correlated (range 0.61-0.78) with other quality-of-life scales and yielded substantially different utility values for patients with different health statuses. Nevertheless, the disease specific preference-based questionnaires showed greater discriminatory power. CONCLUSIONS: Although the Quality of Life Questionnaire Preference-Based Measure and the EORTC-8D appear to have better validity, this study does not provide any strong evidence against the use of the EQ-5D-5L for measuring quality-of-life utilities in acute leukemia. However, our findings need to be confirmed in larger longitudinal studies. PMID- 27712713 TI - Adherence to Self-Care Behaviors among Patients with Type 2 Diabetes-The Role of Risk Preferences. AB - OBJECTIVES: To examine whether the degree of risk aversion is associated with adherence to disease self-management among adults with type 2 diabetes. METHODS: This was a cross-sectional study of patients with type 2 diabetes (n = 408) aged 21 to 70 years who presented for routine visits in the diabetes clinic at a university medical center in Beer-Sheva, Israel. The authors used validated questionnaires to estimate adherence, risk preferences, motivation, self efficacy, impulsivity, perceptions about the disease and the interpersonal process of care, and demographic and socioeconomic characteristics, in addition to retrieving data from computerized patient medical records of clinical indicators of disease severity. Multivariable linear and ordered-logit models examined predictors of adherence to each self-care behavior. RESULTS: Multivariable analyses revealed that, compared with others, risk-seeking patients reported lower general adherence (beta = -0.32; P <= 0.05), and specifically, lower adherence to healthful eating plan (beta = -0.48; P <= 0.1), consumption of low-fat food (beta = -0.47; P <= 0.1), exercise (beta = -0.73; P <= 0.05), blood glucose monitoring (beta = -0.69; P <= 0.05), and foot care (beta = -0.36; P <= 0.1). Risk-seeking patients did not report lower consumption of fruits and vegetables (beta = -0.19; P > 0.1). Because 96% of the study population reported optimal adherence to medication, determinants of this behavior could not be analyzed. CONCLUSIONS: Risk preference is associated with adherence to self-care behaviors. Identifying risk seekers may enable practitioners to target these patients with tailored strategies to improve adherence, thus more efficiently allocating scarce health care resources. PMID- 27712714 TI - Development and Validation of Algorithms to Identify Statin Intolerance in a US Administrative Database. AB - OBJECTIVES: To develop and validate algorithms to define statin intolerance (SI) in an administrative database using electronic medical records (EMRs) as the reference comparison. METHODS: One thousand adults with one or more qualifying changes in statin therapy and one or more previous diagnoses of hyperlipidemia, hypercholesterolemia, or mixed dyslipidemia were identified from the Henry Ford Health System administrative database. Data regarding statin utilization, comorbidities, and adverse effects were extracted from the administrative database and corresponding EMR. Patients were stratified by cardiovascular (CV) risk. SI was classified as absolute intolerance or titration intolerance on the basis of changes in statin utilization and/or the occurrence of adverse effects and laboratory testing for creatine kinase. Measures of concordance (Cohen's kappa [kappa]) and accuracy (sensitivity, specificity, positive predictive value [PPV], and negative predictive value) were calculated for the administrative database algorithms. RESULTS: Half of the sample population was white, 52.9% were women, mean age was 60.6 years, and 35.7% were at high CV risk. SI was identified in 11.5% and 14.0%, absolute intolerance in 2.2% and 3.1%, and titration intolerance in 9.7% and 11.8% of the patients in the EMR and the administrative database, respectively. The algorithm identifying any SI had substantial concordance (kappa = 0.66) and good sensitivity (78.1%), but modest PPV (64.0%). The titration intolerance algorithm performed better (kappa = 0.74; sensitivity 85.4%; PPV 70.1%) than the absolute intolerance algorithm (kappa = 0.40; sensitivity 50%; PPV 35.5%) and performed best in the high CV-risk group (n = 353), with robust concordance (kappa = 0.73) and good sensitivity (80.9%) and PPV (75.3%). CONCLUSIONS: Conservative but comprehensive algorithms are available to identify SI in administrative databases for application in real-world research. These are the first validated algorithms for use in administrative databases available to decision makers. PMID- 27712715 TI - Financing a Cure for Diabetes in a Multipayer Environment. AB - BACKGROUND: Financing medical breakthroughs or cures is becoming increasingly challenging in the current fiscal environment. OBJECTIVES: In this paper, we develop the precise conditions needed for a financing mechanism, HealthCoin, to work between a private payer and Medicare, to incentivize the former to invest in breakthrough therapies or cures in the US. METHODS: We illustrate the valuation of such a currency for a cure of Type 2 diabetes. RESULTS: We show that without a HealthCoin, a private payer does not invest in the cure, a small fraction of the patients live up to age 65, Medicare pays for the full price of the cure at age 65 and incurs net loss in returns over the elderly ages, and the manufacturer only sells cures for those who reach age 65. In contrast, a HealthCoin is feasible in this market, incentivizing the private payer to invest in the cure during the non-elderly ages and leading to Pareto improvements for all three stakeholders. CONCLUSIONS: Discussions around the applicability of HealthCoin for breakthrough therapies on the horizon, such as gene therapies for blindness and hemophilia B, and the feasibility of instituting such payments through new legislations or demonstration projects could be of great value. PMID- 27712716 TI - Increasing Patient Involvement in Drug Development. AB - BACKGROUND: To ensure the creation of treatments that maximize value at the lowest cost, all aspects of the health care system need to align with patient needs and preferences. Despite growing efforts to engage patients in research and regulatory activities, the pharmaceutical industry has yet to maximize patient involvement in the drug development process. OBJECTIVE: To gain a better understanding of the present state of patient involvement in drug development. METHODS: Through a semistructured interview methodology, we sought to identify opportunities, barriers, and examples of patient involvement in the drug development process. Telephone interviews were conducted with six senior leaders of evidence generation within the pharmaceutical industry and four patients. These interviews were supplemented with interviews with a research funder, a regulator, a patient advocacy group, and a caregiver. RESULTS: Although our interviewees spoke of the potential benefits of aligning research around the needs of patients, there were few examples they could share to suggest this was occurring at scale. A number of barriers were identified including the added burden associated with adverse event reporting, concerns about patient representativeness or their ability to participate in drug development conversations, and the costs in time and resources involved relative to returns on investment. CONCLUSIONS: As health care systems continue to evolve and establish patients as the primary stakeholder in their health care decision making, the pharmaceutical industry will need to be innovative to demonstrate the value of their products relative to the outcomes experienced by patients. Pharmaceutical companies should recognize the value of involving patients across the entire product life cycle and work to transform present perceptions and practices throughout their organizations. PMID- 27712717 TI - Did It Matter That the Cancer Drugs Fund Was Not NICE? A Retrospective Review. AB - BACKGROUND: The Cancer Drugs Fund (CDF) will have spent more than L1 billion between October 2010 and the introduction of reforms to its structure and operations in July 2016. There has been much more debate about the existence of the fund than about how it spent its substantial budget. It is important to undertake a retrospective examination of "where the money went" in light of the substantial reforms that will be introduced in 2016. OBJECTIVES: We review the means by which the CDF made recent funding decisions for cancer drugs to provide an assessment of the merits of the CDF "model" as a basis for allocation decisions. We assess the extent to which proposed reforms could overcome defects in the original CDF model of prioritization, and lessons for other countries. METHODS: We provide a narrative commentary on CDF's methods and processes since 2014. We evaluate methods against best practice in cost-effectiveness analysis, and processes against the "accountability for reasonableness" framework. We comment on reforms to the fund. RESULTS: There are no grounds for concluding that the opportunity costs imposed on cancer patients were well evidenced, or the product of legitimate deliberative processes. We note that some of these issues will be addressed in the next incarnation of the fund, but the rationale for the fund's existence remains unconvincing. CONCLUSIONS: It is important and timely to debate how cancer drugs appraisal ought to be conducted to confront the consequences of CDF's model of appraisal. We conclude that it did matter that the CDF was not NICE. PMID- 27712718 TI - A Comprehensive Algorithm for Approval of Health Technologies With, Without, or Only in Research: The Key Principles for Informing Coverage Decisions. AB - BACKGROUND: The value of evidence about the performance of a technology and the value of access to a technology are central to policy decisions regarding coverage with, without, or only in research and managed entry (or risk-sharing) agreements. OBJECTIVES: We aim to outline the key principles of what assessments are needed to inform "only in research" (OIR) or "approval with research" (AWR) recommendations, in addition to approval or rejection. METHODS: We developed a comprehensive algorithm to inform the sequence of assessments and judgments that lead to different types of guidance: OIR, AWR, Approve, or Reject. This algorithm identifies the order in which assessments might be made, how similar guidance might be arrived at through different combinations of considerations, and when guidance might change. RESULTS: The key principles are whether the technology is expected to be cost-effective; whether the technology has significant irrecoverable costs; whether additional research is needed; whether research is possible with approval and whether there are opportunity costs that once committed by approval cannot be recovered; and whether there are effective price reductions. Determining expected cost-effectiveness is only a first step. In addition to AWR for technologies expected to be cost-effective and OIR for those not expected to be cost-effective, there are other important circumstances when OIR should be considered. CONCLUSIONS: These principles demonstrate that cost effectiveness is a necessary but not sufficient condition for approval. Even when research is possible with approval, OIR may be appropriate when a technology is expected to be cost-effective due to significant irrecoverable costs. PMID- 27712719 TI - Economic Impact of Integrated Care Models for Patients with Chronic Diseases: A Systematic Review. AB - OBJECTIVES: To assess the costs and potential financial benefits of integrated care models for patients with chronic diseases, that is, type 2 diabetes mellitus, schizophrenia, and multiple sclerosis, respectively. METHODS: A systematic search of the literature was performed using EMBASE, MEDLINE, and Web of Science. Studies that conducted a cost analysis, considered at least two components of the chronic care model, and compared integrated care with standard care were included. RESULTS: Out of 575 articles, 26 were included. Most studies examined integrated care models for type 2 diabetes mellitus (n = 18) and to a lesser extent for schizophrenia (n = 6) and multiple sclerosis (n = 2). Across the three disease groups, the incremental cost per patient per year ranged from - ?3860 to + ?613.91 (x- = - ?533.61 +/- ?902.96). The incremental cost for type 2 diabetes mellitus ranged from - ?1507.49 to + ?299.20 (x- = - ?518.22 +/- + ?604.75), for schizophrenia from - ?3860 to + ?613.91 (x- = - ?677.21 +/- + ?1624.35), and for multiple sclerosis from - ?822 to + ?339.43 (x- = - ?241.29 +/ + ?821.26). Most of the studies (22 of 26 [84.6%]) reported a positive economic impact of integrated care models: for type 2 diabetes mellitus (16 of 18 [88.9%]), schizophrenia (4 of 6 [66.7%]), and multiple sclerosis (1 of 2 [50%]). CONCLUSIONS: In this systematic literature review, predominantly positive economic impacts of integrated care models for patients with chronic diseases were found. PMID- 27712720 TI - A Systematic Review of Health Economic Evaluation Studies Using the Patient's Perspective. AB - BACKGROUND: Patient-centered care has become increasingly important and relevant for informed health care decision making. OBJECTIVE: Our study aimed to perform a systematic review of health economic evaluation studies from the patient's perspective. METHODS: PubMed, EMBASE, and Cochrane Central databases were searched through May 2014 for cost-effectiveness, cost-utility, and cost-benefit studies using the patient's perspective in their analysis. The reporting quality of the studies was evaluated on the basis of Consolidated Health Economic Evaluation Reporting Standards. RESULTS: We identified 30 health economic evaluations using the patient's perspective, of which 7 were conducted in the United States, 9 in Europe, and 14 in Asian or other countries. Seventeen of 23 health conditions evaluated were chronic in nature. Among 12 studies that justified the use of the patient's perspective, patient's financial burden associated with medical treatment was the most commonly cited rationale. A total of 29, 17, and 15 studies examined direct medical, direct nonmedical, and indirect costs, respectively. Seventeen studies also included societal, governmental or payer's, and/or provider's perspective(s) in their analyses. Based on Consolidated Health Economic Evaluation Reporting Standards, more than 20% of the reporting items in these studies were either partially satisfied or not satisfied. CONCLUSIONS: There is a paucity of health economic evaluations conducted from the patient's perspective in the literature. For those studies using the patient's perspective, the true patient costs were not fully explored and study reporting quality was not optimal. With the increasing focus on patient centered outcomes in health policy research, more frequent use of the patient's perspective in economic studies should be advocated. PMID- 27712721 TI - Redox-electrodes for selective electrochemical separations. AB - Redox-active materials hold great promise as platforms for selective liquid-phase separations. In contrast to capacitive electrodes that rely purely on double layer charge for deionization, redox-modified electrodes can be used to control Faradaic reactions at the interface to selectively bind various charged and uncharged molecules, thus modulating surface interactions through electrochemical potential solely. These electrodes can be composed of a range of functional materials, from organic and organometallic polymers to inorganic crystalline compounds, each relying on its own distinct ion-exchange process. Often, redox electrochemical systems can serve as pseudocapacitors or batteries, thus offering an advantageous combination of adsorption selectivity and energy storage/recovery. This review summarizes redox-interfaces for electrosorption and release, outlines methods for preparation and synthesis, discusses the diverse mechanisms for interaction, and gives a perspective on the future of redox mediated separations.

AB - Intravascular ultrasound has been used for >20 years to guide percutaneous coronary intervention in different subsets of coronary lesions. During the last decade, the interest in percutaneous coronary intervention for chronic total occlusion (CTO) has increased dramatically, leading to high success rates. Failure of guidewire crossing is the most common reason for failed CTO attempts. Certain angiographic features, such as blunt proximal CTO cap, tortuosity, heavy calcification, and lack of visibility of path in the distal vessel, increase procedural difficulty. A better understanding of the behavior of the guidewire within the CTO segment may represent a key issue to achieve successful outcome. In this respect, intravascular ultrasound imaging might have potential roles in the recanalization of CTOs. In this paper, we focused on the usefulness and the applications of intravascular ultrasound imaging in percutaneous CTO recanalization, underlying its impact on clinical outcome. PMID- 27712733 TI - Prevention of Radial Artery Occlusion After Transradial Catheterization: The PROPHET-II Randomized Trial. AB - OBJECTIVES: The study sought to evaluate whether prophylactic ipsilateral ulnar artery compression during radial artery hemostasis could reduce the risk of radial artery occlusion (RAO). BACKGROUND: RAO after transradial access (TRA) is a structural complication of TRA. It limits future ipsilateral TRA and may cause transient pain. Maintaining radial artery flow during hemostasis reduces the incidence of acute RAO. Ipsilateral ulnar compression increases radial artery flow and could impact the incidence of RAO. METHODS: Three thousand patients undergoing diagnostic cardiac catheterization using TRA were randomized to receive either standard patent hemostasis protocol (Group I) or prophylactic ipsilateral ulnar compression in addition to patent hemostasis (Group II). Using plethysmography, radial artery patency was evaluated at the time of removal of the compression device as well as 24 h and 30 days after the procedure. The primary study endpoint was 30-day RAO. RESULTS: The primary endpoint, 30-day RAO, was significantly reduced in patients with patent hemostasis and prophylactic ulnar compression compared with standard patent hemostasis (0.9% vs. 3.0%; p = 0.0001). Baseline patient and procedural characteristics were similar between the 2 groups. RAO was significantly reduced by prophylactic ulnar compression at all time intervals (p < 0.0001). CONCLUSIONS: Prophylactic ipsilateral ulnar compression during radial artery hemostasis is an effective, simple, and inexpensive technique that lowers the risk of RAO after TRA.

PMID- 27712735 TI - Does Residual Thrombus After Aspiration Thrombectomy Affect the Outcome of Primary PCI in Patients With ST-Segment Elevation Myocardial Infarction?: An Optical Coherence Tomography Study. AB - OBJECTIVES: The aim of this study was to evaluate if residual thrombus burden after aspiration thrombectomy affects the outcomes of primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction (STEMI). BACKGROUND: Recent studies failed to show clinical benefit of aspiration thrombectomy in STEMI patients. This might be due to insufficient removal of thrombus at the culprit lesion. METHODS: A total of 109 STEMI patients who underwent aspiration thrombectomy followed by stenting within 24 h from symptom onset were included. Optical coherence tomography was performed after thrombectomy to measure residual thrombus burden. Patients were divided into tertiles based on the amount of residual thrombus and the outcomes were compared. RESULTS: Myocardial no reflow, defined as TIMI (Thrombolysis In Myocardial Infarction) flow grade of <=2 and/or myocardial blush grade of <=1 after stenting, was more observed frequently in patients in the highest tertile compared with those in the lowest tertile (44.4% vs. 16.7%; p = 0.001). Patients in the highest tertile also had greater myocardial damage measured by creatine kinase MB compared with those in the lowest tertile (p = 0.002). CONCLUSIONS: STEMI patients with greater residual thrombus burden after aspiration thrombectomy had worse microvascular dysfunction and greater myocardial damage compared with those with smaller residual thrombus burden.

PMID- 27712737 TI - Safety and Efficacy of a Pharmacoinvasive Strategy in ST-Segment Elevation Myocardial Infarction: A Patient Population Study Comparing a Pharmacoinvasive Strategy With a Primary Percutaneous Coronary Intervention Strategy Within a Regional System. AB - OBJECTIVES: This study investigated the safety and efficacy of a pharmacoinvasive strategy compared with a primary percutaneous coronary intervention (PCI) strategy for ST-segment elevation myocardial infarction (STEMI) in the context of a real-world system. BACKGROUND: Primary PCI continues to be the optimal reperfusion therapy; however, in areas where PCI centers are not readily available, a pharmacoinvasive strategy has been proposed. METHODS: The University of Ottawa Heart Institute regional STEMI system provides a primary PCI strategy for patients presenting within a 90-km radius from the PCI center, and a pharmacoinvasive strategy for patients outside this limit. We included all confirmed STEMI patients between April 2009 and May 2011. The primary efficacy outcome was a composite of mortality, reinfarction, or stroke and the primary safety outcome was major bleeding. RESULTS: We identified 236 and 980 consecutive patients enrolled in pharmacoinvasive and primary PCI strategies, respectively. The median door-to-needle time was 31 min in the pharmacoinvasive group and the median door-to-balloon time was 95 min in the primary PCI group. In a multivariable model, there was no significant difference in the primary efficacy outcome (odds ratio: 1.54; p = 0.21); however, the propensity for more bleeding with a pharmacoinvasive strategy approached statistical significance (odds ratio: 2.02; p = 0.08). CONCLUSIONS: Within the context of a STEMI system, a pharmacoinvasive strategy was associated with similar rates of the composite of mortality, reinfarction, or stroke as compared with a primary PCI strategy; however, there was a propensity for more bleeding with a pharmacoinvasive strategy.

PMID- 27712739 TI - Diagnostic Accuracy of Fast Computational Approaches to Derive Fractional Flow Reserve From Diagnostic Coronary Angiography: The International Multicenter FAVOR Pilot Study. AB - OBJECTIVES: The aim of this prospective multicenter study was to identify the optimal approach for simple and fast fractional flow reserve (FFR) computation from radiographic coronary angiography, called quantitative flow ratio (QFR). BACKGROUND: A novel, rapid computation of QFR pullbacks from 3-dimensional quantitative coronary angiography was developed recently. METHODS: QFR was derived from 3 flow models with: 1) fixed empiric hyperemic flow velocity (fixed flow QFR [fQFR]); 2) modeled hyperemic flow velocity derived from angiography without drug-induced hyperemia (contrast-flow QFR [cQFR]); and 3) measured hyperemic flow velocity derived from angiography during adenosine-induced hyperemia (adenosine-flow QFR [aQFR]). Pressure wire-derived FFR, measured during maximal hyperemia, served as the reference. Separate independent core laboratories analyzed angiographic images and pressure tracings from 8 centers in 7 countries. RESULTS: The QFR and FFR from 84 vessels in 73 patients with intermediate coronary lesions were compared. Mean angiographic percent diameter stenosis (DS%) was 46.1 +/- 8.9%; 27 vessels (32%) had FFR <= 0.80. Good agreement with FFR was observed for fQFR, cQFR, and aQFR, with mean differences of 0.003 +/- 0.068 (p = 0.66), 0.001 +/- 0.059 (p = 0.90), and -0.001 +/- 0.065 (p = 0.90), respectively. The overall diagnostic accuracy for identifying an FFR of <=0.80 was 80% (95% confidence interval [CI]: 71% to 89%), 86% (95% CI: 78% to 93%), and 87% (95% CI: 80% to 94%). The area under the receiver-operating characteristic curve was higher for cQFR than fQFR (difference: 0.04; 95% CI: 0.01 to 0.08; p < 0.01), but did not differ significantly between cQFR and aQFR (difference: 0.01; 95% CI: -0.04 to 0.06; p = 0.65). Compared with DS%, both cQFR and aQFR increased the area under the receiver-operating characteristic curve by 0.20 (p < 0.01) and 0.19 (p < 0.01). The positive likelihood ratio was 4.8, 8.4, and 8.9 for fQFR, cQFR, and aQFR, with negative likelihood ratio of 0.4, 0.3, and 0.2, respectively. CONCLUSIONS: The QFR computation improved the diagnostic accuracy of 3-dimensional quantitative coronary angiography-based identification of stenosis significance. The favorable results of cQFR that does not require pharmacologic hyperemia induction bears the potential of a wider adoption of FFR based lesion assessment through a reduction in procedure time, risk, and costs.

PMID- 27712741 TI - Transcatheter Mitral Annuloplasty in Chronic Functional Mitral Regurgitation: 6 Month Results With the Cardioband Percutaneous Mitral Repair System. AB - OBJECTIVES: This study sought to show safety and efficacy of the Cardioband system during 6 months after treatment. BACKGROUND: Current surgical and medical treatment options for functional mitral regurgitation (FMR) are limited. The Cardioband system (Valtech Cardio, OrYehuda, Israel) is a novel transvenous, transseptal direct annuloplasty device. METHODS: Thirty-one patients (71.8 +/- 6.9 years of age; 83.9% male; EuroSCORE II: 8.6 +/- 5.9) with moderate to severe FMR, symptomatic heart failure, and depressed left ventricular function (left ventricular ejection fraction 34 +/- 11%) were prospectively enrolled. RESULTS: Procedural success rate, defined as delivery of the entire device, was 100%. There were no periprocedural deaths (0%), and mortality rate at 1 month or prior to hospital discharge and at 7 months was 5% and 9.7% respectively. Cinching of the implanted Cardioband reduced the annular septolateral dimension by >30% from 3.7 +/- 0.5 cm at baseline to 2.5 +/- 0.4 cm after 1 month and to 2.4 +/- 0.4 cm after 6 months, respectively (p < 0.001). Percentage of patients with FMR >=3 was reduced from 77.4% to 10.7% 1 month after the procedure (p < 0.001) and 13.6% (p < 0.001) at 7 months. Percentage of patients with New York Heart Association functional class III/IV decreased from 95.5% to 18.2% after 7 months (p < 0.001); exercise capacity as assessed by 6-min walking test increased from 250 +/- 107 m to 332 +/- 118 m (p < 0.001) and quality of life (Minnesota Living With Heart Failure Questionnaire) was also significantly improved (p < 0.001). CONCLUSIONS: In this feasibility trial in symptomatic patients with FMR, transcatheter mitral annuloplasty with the Cardioband was effective in reducing MR and was associated with improvement in heart failure symptoms and demonstrated a favorable safety profile.

PMID- 27712746 TI - Setting the Goals in the Management of Mutilated Injuries of the Hand-Impressions Based on the Ganga Hospital Experience. AB - Mutilated injuries need to be treated aggressively and appropriately to avoid amputation or severe disability in the individual. Assessment of the management of these injuries on a global level reveals that there is a gap between the need and availability of the skilled manpower to manage these injuries. There is also a gap in the utilization of the available services. These gaps need to be covered or narrowed as far as possible. Although some measures need policy changes and improvement of health care delivery infrastructure, simpler measures taken at the final health care delivery level can significantly improve the final outcome. PMID- 27712747 TI - The Biomechanical Impact of Digital Loss and Fusion Following Trauma: Setting the Patient up for Success. AB - Surgeons managing mutilating hand injures are faced with difficult decisions between attempting to salvage remaining or injured digits or proceeding to amputation and fusion. Through application of a basic understanding of hand biomechanics, the surgeon may more accurately predict what motion and function can best be salvaged. This article provides an explanation of how amputation, fusion, and tendon loss can affect postoperative hand motion. The surgeon can use these concepts in planning the reconstruction or preparing the foundation for secondary reconstructive procedures to achieve the highest functional outcome for the patient. PMID- 27712749 TI - Mutilating Hand Injuries in Children. AB - Mutilating hand injuries in children are injuries that are significant not only because of the actual injury caused to tissue but also owing to the significant psychological impact they have on the patient and family alike. Management of these injuries requires significant surgical skill as well as a well-planned and well-executed treatment protocol. This article discusses the etiology, incidence as well as treatment of mutilating hand injuries in a child. Relevant literature has been reviewed and appropriate treatment guidelines have been provided. PMID- 27712748 TI - Measuring Functional and Patient-Reported Outcomes After Treatment of Mutilating Hand Injuries: A Global Health Approach. AB - Understanding the global burden of trauma, particularly upper extremity trauma, is necessary in addressing the need for surgical services. Critical to that mission is to understand, and accurately measure, disability and related disability-adjusted life-years from massive upper extremity trauma. The impact of these injuries is magnified when considering that they frequently occur to young people in prime working years. This article discusses these social and medical system issues and reviews components of a comprehensive approach to measuring outcomes after these injuries. Patient-reported outcomes are highlighted. Methods of optimizing outcomes measurements and studies, disability assessments, and associated research are also discussed. PMID- 27712750 TI - Skin Coverage Considerations in a Mutilating Hand Injury. AB - The foremost goal of managing a mutilated hand is provision of adequate skin coverage. The most suitable method is free tissue transfer. The specific role of volar surface requires replacement tissue to have similar texture for aesthetically satisfactory and functionally acceptable outcomes. Hand surgeons must approach mutilating hand injuries with the recognition that no 2 injuries are ever the same. The injured hand must be evaluated on the individual demand and characteristics of hand use. Optimal function and aesthetic outcomes require appropriate selection of skin coverage. Lost tissues must be replaced like with like tissue. PMID- 27712751 TI - Skeletal Fixation in a Mutilated Hand. AB - Hand fracture fixation in mutilating injuries is characterized by multiple challenges due to possible skeletal disorganization and concomitant severe injury of soft tissue structures. The effects of skeletal disruption are best analyzed as divided into specific locales in the hand: radial, ulnar, proximal, and distal. Functional consequences of injuries in each of these regions are discussed. Although a variety of implants are now in vogue, K-wire fixation has stood the test of time and is especially useful in multiple fracture situations. Segmental bone loss is quite common in such injuries, which can be safely reconstructed in a staged manner. PMID- 27712752 TI - Primary Thumb Reconstruction in a Mutilated Hand. AB - The thumb should be preserved at all costs, and major efforts to preserve it are justified. If nothing can be done (or desperate measures fail), classic procedures or a toe-to-hand are indicated. This article will not only discuss some tips to succeed in extreme acute scenarios, but will also consider the indications of other alternatives in the acute or subacute setting. PMID- 27712753 TI - Secondary Thumb Reconstruction in a Mutilated Hand. AB - The thumb plays an integral role in hand function. Traumatic amputation results in significant morbidity. With loss of the thumb, up to a 40% reduction in hand function may result. Thumb replantation must be attempted when possible. The goals of thumb reconstruction are to replicate normal function as closely as possible, minimize donor site morbidity, and expedite recovery. In the setting of a mutilated hand, the status of the remaining digits must be carefully assessed. Toe transfers, osteoplastic thumb reconstruction, and pollicization are commonly used. This article summarizes the indications and technical considerations in addressing the deficiencies after thumb amputation. PMID- 27712754 TI - Metacarpal-Like and Metacarpal Hand. AB - The metacarpal-like and metacarpal hand injuries are devastating conditions that render the hand nonfunctional. Although the metacarpal hand is well-studied, the metacarpal-like hand is never addressed. The authors, using the same principles as in the classification and treatment of metacarpal hand, propose an easy to follow treatment algorithm for metacarpal-like hand injury to guide the reconstructive surgeon. For both injuries, microsurgical toe-to-hand transplantation can restore an acceptable level of function if done properly. Meticulous planning is essential for the toe-to-hand surgery to achieve its prime goal of stable tripod pinch with insignificant morbidity at the donor sites. PMID- 27712755 TI - Secondary Interventions for Mutilating Hand Injuries. AB - Care of the reconstructed hand following mutilating injury is akin to the care of a vintage car. Its mechanisms are delicate, spare parts are limited, touch-ups are required often, and a major overhaul is indicated rarely. Secondary interventions are indicated for completion of staged primary procedures, management of complications, targeted improvement of function, and enhancement of appearance of the reconstructed hand. The approach to secondary reconstruction depends on the patient's age, and vocational and recreational requirements. It is also influenced by the constant evolution of surgeons' reconstructive philosophy, experience, and technology. PMID- 27712756 TI - Challenges Posed by Delayed Presentation of Mutilating Hand Injuries. AB - Management of mutilating hand injury is a challenge for any hand surgeon. Delay in presentation makes management even more challenging, usually because of inadequate initial assessment, inadequate debridement leading to infection, and secondary loss of tissues from exposure and desiccation. The aim is to obtain a functional hand by radical debridement, adequate assessment of the injury, appropriately timed reconstruction, and physiotherapy and rehabilitation. The hand surgeon must pay attention to the appearance of the hand by elimination of deformities, unsightly scars and bulky flaps to help to restore confidence in the patient to face the demands of daily living. PMID- 27712757 TI - Pushing the Boundaries of Salvage in Mutilating Upper Limb Injuries: Techniques in Difficult Situations. AB - With the available microsurgical techniques, salvage of the limb can almost always provide a useful upper limb, even in the most complex combined injuries. Having a low threshold for revascularization of doubtfully viable extremities and making full use of the current armamentarium of soft tissue cover techniques, including flow through free flaps, will salvage many limbs. Secondary procedures, including free functioning muscle transfers and toe transfers, further increase the possible functional outcome. Even in the most complex combined injuries, intelligent reconstruction will obtain better outcomes than the best available prosthesis, making the efforts of salvage worthwhile. PMID- 27712758 TI - Reconstructing Lives. PMID- 27712759 TI - An Overview of Nonsteroidal Antiinflammatory Drug Reactions. AB - Nonsteroidal antiinflammatory drugs (NSAIDs), including aspirin, are among the most commonly used drugs worldwide. They account for a large number of adverse drug reactions (ADRs). The prevalence of NSAID-induced reactions is increasing. Distinguishing between a predicted side effect of a drug and a potentially life threatening hypersensitivity reaction is essential to manage the affected patient. However, most clinicians find it difficult to diagnose these types of reactions despite published classification schemes. In this overview, we provide an in-depth review of NSAID classification, types of NSAID reactions, diagnostic tactics, and management strategies to provide the reader with a greater understanding of NSAID-induced reactions. PMID- 27712760 TI - Clinical Characteristics of Aspirin-Exacerbated Respiratory Disease. AB - Aspirin-exacerbated respiratory disease is a significant endotype of both asthma and chronic rhinosinusitis with nasal polyps. The disease demonstrates what seems to be a unified inflammatory mechanism culminating in highly eosinophilic nasal polyp disease and asthma. The rate of polyp recurrence and morbidity from asthma exacerbations are significant and warrant separating this group diagnostically from aspirin-tolerant peers. Given the unique anti-inflammatory effects of aspirin and the evolving landscape of new, targeted biologic treatments, it is even more incumbent to consider this diagnosis and offer patients treatment specific for the disease. PMID- 27712761 TI - Diagnostic Evaluation in Aspirin-Exacerbated Respiratory Disease. AB - Aspirin-exacerbated respiratory disease (AERD) is a distinct clinical condition characterized by chronic sinusitis with nasal polyps, asthma, and hypersensitivity reactions to nonsteroidal anti-inflammatory drugs (NSAIDs). Distinguishing AERD from other forms of chronic sinusitis, asthma, and NSAID reactivity has important clinical implications for management. The clinical history is helpful, but not adequate for confirming the diagnosis of AERD, in most cases. Diagnostic provocation challenge remains the only way to confirm or exclude the diagnosis of AERD. This article discusses the utility of the clinical history and the current evidence regarding measures that optimize the safety of performing diagnostic NSAID provocation challenges. PMID- 27712762 TI - Aspirin-Exacerbated Respiratory Disease as an Endotype of Chronic Rhinosinusitis. AB - Aspirin-Exacerbated Respiratory Disease (AERD) and Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) are both characterized by the presence of chronic sinonasal inflammation and nasal polyps. Unlike in CRSwNP, AERD patients develop respiratory reactions following ingestion of COX-1 inhibitors. AERD patients also, on average, have worse upper respiratory disease with increased sinonasal symptoms, mucosal inflammation and requirements for revision sinus surgery when compared to CRSwNP patients. While no single genetic factor has been identified in either CRSwNP or AERD to date, differences in the metabolism of arachidonic acid as well as innate immune cell activation may uniquely contribute to AERD pathogenesis. PMID- 27712763 TI - Pathogenesis of Aspirin-Induced Reactions in Aspirin-Exacerbated Respiratory Disease. AB - The acute clinical symptoms that develop following the oral ingestion of aspirin, or any other inhibitor of cyclooxygenase-1, are well established in aspirin exacerbated respiratory disease: nasal congestion, rhinorrhea, and bronchospasm. Less commonly, gastrointestinal distress, rash, angioedema, or urticaria also develops. However, the pathobiology that drives these clinical reactions is poorly understood. Use of an intranasal aspirin challenge protocol or administration of premedications inhibiting the leukotriene pathway decreases the severity of clinical reaction, which suggests the involvement of both local effector cells and cysteinyl leukotrienes in the pathogenesis of aspirin-induced reactions. PMID- 27712764 TI - Performing Aspirin Desensitization in Aspirin-Exacerbated Respiratory Disease. AB - Aspirin-exacerbated respiratory disease (AERD) is characterized by chronic rhinosinusitis with nasal polyps, asthma, and reactions to cyclooxygenase-1 inhibiting drugs. This condition is often refractory to standard medical treatments and results in aggressive nasal polyposis that often requires multiple sinus surgeries. Aspirin desensitization followed by daily aspirin therapy is an important treatment option, and its efficacy has been validated in multiple research studies. Aspirin desensitization is not without risk, but specific protocols and recommendations exist to mitigate the risk. Most patients with AERD can undergo aspirin desensitization in an outpatient setting under the supervision of an allergist. PMID- 27712765 TI - Clinical Trials of Aspirin Treatment After Desensitization in Aspirin-Exacerbated Respiratory Disease. AB - The clinical efficacy of aspirin treatment after desensitization in patients with respiratory disease exacerbated by nonsteroidal anti-inflammatory drugs has been documented in observational studies and in double-blind placebo-controlled trials. There is no general agreement with regard to the optimal maintenance dose or duration of treatment with acetylsalicylic acid after desensitization, thus further studies are necessary to offer clear guidelines to clinicians. This article summarizes data from noncontrolled, active-control, and placebo controlled trials assessing clinical effectiveness and reporting on safety of treatment with acetylsalicylic acid in desensitized patients with respiratory disease exacerbated by nonsteroidal anti-inflammatory drugs. PMID- 27712767 TI - Mechanisms of Benefit with Aspirin Therapy in Aspirin-Exacerbated Respiratory Disease. AB - Aspirin-exacerbated respiratory disease (AERD) is a clinical syndrome characterized by severe persistent asthma, hyperplastic eosinophilic sinusitis with nasal polyps, and an intolerance to aspirin and other NSAIDs that preferentially inhibit COX-1. For more than 30 years, aspirin desensitization has proven to be of significant long-term benefit in carefully selected patients with AERD. Despite this, the exact mechanisms behind the therapeutic effects of aspirin desensitization remain poorly understood. In this article, we review the current understanding of the mechanisms of aspirin desensitization and discuss future areas of investigation. PMID- 27712766 TI - Eosinophils and Mast Cells in Aspirin-Exacerbated Respiratory Disease. AB - Aspirin-exacerbated respiratory disease (AERD) involves overexpression of proinflammatory mediators, including 5-lipoxygenase and leukotriene C4 synthase (LTC4S), resulting in constitutive overproduction of cysteinyl leukotrienes. Mast cells and eosinophils have roles in mediating many of the observed effects. Increased levels of both interleukin-4 (IL-4) and interferon (IFN)-gamma are present in the tissue of patients with AERD. Previous studies showed that IL-4 is primarily responsible for the upregulation of LTC4S by mast cells. Our studies show that IFN-gamma, but not IL-4, drives this process in eosinophils. This article examines the overall role that eosinophils and mast cells contribute to the pathophysiology of AERD. PMID- 27712768 TI - Lipid Mediators in Aspirin-Exacerbated Respiratory Disease. AB - Aspirin-exacerbated respiratory disease (AERD) is a syndrome of severe asthma and rhinosinusitis with nasal polyposis with exacerbations of baseline eosinophil driven and mast cell-driven inflammation after nonsteroidal antiinflammatory drug ingestion. Although the underlying pathophysiology is poorly understood, dysregulation of the cyclooxygenase and 5-lipoxygenase pathways of arachidonic acid metabolism is thought to be key. Central features of AERD pathogenesis are overproduction of proinflammatory and bronchoconstrictor cysteinyl leukotrienes and prostaglandin (PG) D2 and inhibition of bronchoprotective and antiinflammatory PGE2. Imbalance in the ratio of these lipid mediators likely leads to the increased eosinophilic and mast cell inflammatory responses in the respiratory tract.

PMID- 27712769 TI - Genetic and Epigenetic Components of Aspirin-Exacerbated Respiratory Disease. AB - Aspirin-exacerbated respiratory disease (AERD) severity and its clinical phenotypes are characterized by genetic variation within pathways for arachidonic acid metabolism, inflammation, and immune responses. Epigenetic effects, including DNA methylation and histone protein modification, contribute to regulation of many genes that contribute to inflammatory states in AERD. The development of noninvasive, predictive clinical tests using data from genetic, epigenetic, pharmacogenetic, and biomarker studies will improve precision medicine efforts for AERD and asthma treatment.

PMID- 27712772 TI - Sodium Intake and All-Cause Mortality Over 20 Years in the Trials of Hypertension Prevention. AB - BACKGROUND: The relationship between lower sodium intake and total mortality remains controversial. OBJECTIVES: This study examined the relationship between well-characterized measures of sodium intake estimated from urinary sodium excretion and long-term mortality. METHODS: Two trials, phase I (1987 to 1990), over 18 months, and phase II (1990 to 1995), over 36 months, were undertaken in TOHP (Trials of Hypertension Prevention), which implemented sodium reduction interventions. The studies included multiple 24-h urine samples collected from pre-hypertensive adults 30 to 54 years of age during the trials. Post-trial deaths were ascertained over a median 24 years, using the National Death Index. The associations between mortality and the randomized interventions as well as with average sodium intake were examined. RESULTS: Among 744 phase I and 2,382 phase II participants randomized to sodium reduction or control, 251 deaths occurred, representing a nonsignificant 15% lower risk in the active intervention (hazard ratio [HR]: 0.85; 95% confidence interval [CI]: 0.66 to 1.09; p = 0.19). Among 2,974 participants not assigned to an active sodium intervention, 272 deaths occurred. There was a direct linear association between average sodium intake and mortality, with an HR of 0.75, 0.95, and 1.00 (references) and 1.07 (p trend = 0.30) for <2,300, 2,300 to <3,600, 3,600 to <4,800, and >=4,800 mg/24 h, respectively; and with an HR of 1.12 per 1,000 mg/24 h (95% CI: 1.00 to 1.26; p = 0.05). There was no evidence of a J-shaped or nonlinear relationship. The HR per unit increase in sodium/potassium ratio was 1.13 (95% CI: 1.01 to 1.27; p = 0.04). CONCLUSIONS: We found an increased risk of mortality for high-sodium intake and a direct relationship with total mortality, even at the lowest levels of sodium intake. These results are consistent with a benefit of reduced sodium and sodium/potassium intake on total mortality over a 20-year period.

PMID- 27712774 TI - Percutaneous Intervention for Concurrent Chronic Total Occlusions in Patients With STEMI: The EXPLORE Trial. AB - BACKGROUND: In 10% to 15% of patients with ST-segment elevation myocardial infarction (STEMI), concurrent coronary chronic total occlusion (CTO) in a non infarct-related artery is present and is associated with increased morbidity and mortality. OBJECTIVES: The EXPLORE (Evaluating Xience and Left Ventricular Function in Percutaneous Coronary Intervention on Occlusions After ST-Elevation Myocardial Infarction) trial evaluated whether patients with STEMI and concurrent CTO in a non-infarct-related artery benefit from additional percutaneous coronary intervention (PCI) of CTO shortly after primary PCI. METHODS: From November 2007 through April 2015, we enrolled 304 patients with acute STEMI who underwent primary PCI and had concurrent CTO in 14 centers in Europe and Canada. A total of 150 patients were randomly assigned to early PCI of the CTO (CTO PCI), and 154 patients were assigned to conservative treatment without PCI of the CTO (no CTO PCI). Primary outcomes were left ventricular ejection fraction (LVEF) and left ventricular end diastolic volume (LVEDV) on cardiac magnetic resonance imaging after 4 months. RESULTS: The investigator-reported procedural success rate in the CTO PCI arm of the trial was 77%, and the adjudicated success rate was 73%. At 4 months, mean LVEF did not differ between the 2 groups (44.1 +/- 12.2% vs. 44.8 +/ 11.9%, respectively; p = 0.60). Mean LVEDV at 4 months was 215.6 +/- 62.5 ml in the CTO PCI arm versus 212.8 +/- 60.3 ml in the no-CTO PCI arm (p = 0.70). Subgroup analysis revealed that patients with CTO located in the left anterior descending coronary artery who were randomized to the CTO PCI strategy had significantly higher LVEF compared with patients randomized to the no-CTO PCI strategy (47.2 +/- 12.3% vs. 40.4 +/- 11.9%; p = 0.02). There were no differences in terms of 4-month major adverse coronary events (5.4% vs. 2.6%; p = 0.25). CONCLUSIONS: Additional CTO PCI within 1 week after primary PCI for STEMI was feasible and safe. In patients with STEMI and concurrent CTO, we did not find an overall benefit for CTO PCI in terms of LVEF or LVEDV. The finding that early CTO PCI in the left anterior descending coronary artery subgroup was beneficial warrants further investigation.

METHODS: Simultaneous pressure and flow were measured in the proximal left anterior descending artery in 33 patients with HCM and 20 control patients at rest and during hyperemia, allowing calculation of wave intensity. Patients also underwent quantitative first-pass perfusion cardiac magnetic resonance to measure myocardial perfusion reserve. RESULTS: Patients with HCM had a lower coronary flow reserve than control subjects (1.9 +/- 0.8 vs. 2.7 +/- 0.9; p = 0.01). Coronary hemodynamics in HCM were characterized by a very large backward compression wave during systole (38 +/- 11% vs. 21 +/- 6%; p < 0.001) and a proportionately smaller backward expansion wave (27% +/- 8% vs. 33 +/- 6%; p = 0.006) compared with control subjects. Patients with severe left ventricular outflow tract obstruction had a bisferiens pressure waveform resulting in an additional proximally originating deceleration wave during systole. The proportion of waves acting to accelerate coronary flow increased with hyperemia, and the magnitude of change was proportional to the myocardial perfusion reserve (rho = 0.53; p < 0.01). CONCLUSIONS: Coronary flow in patients with HCM is deranged. Distally, compressive deformation of intramyocardial blood vessels during systole results in an abnormally large backward compression wave, whereas proximally, severe left ventricular outflow tract obstruction is associated with an additional deceleration wave. Perfusion abnormalities in HCM are not simply a consequence of supply/demand mismatch or remodeling of the intramyocardial blood vessels; they represent a dynamic interaction with the mechanics of myocardial ischemia that may be amenable to treatment.

AB - BACKGROUND: Carbamylation alters low-density lipoprotein (LDL) structure and is thought to promote vascular inflammation and dysfunction in patients with chronic kidney disease (CKD). OBJECTIVES: This study sought to determine whether carbamylated LDL (cLDL) exerts prothrombotic effects in vascular cells and platelets and whether cLDL enhances arterial thrombus formation in vivo. METHODS: LDL was isolated from healthy subjects or patients with CKD by sequential ultracentrifugation. Ex vivo carbamylation of LDL from healthy subjects was induced with potassium cyanate. Arterial thrombus formation was analyzed in a murine carotid artery photochemical injury model. Protein expression and mRNA levels were analyzed by Western blotting, flow cytometry, and real-time PCR. Platelet aggregation was measured by impedance aggregometry. RESULTS: Intravenous administration of cLDL in mice accelerated arterial thrombus formation compared to treatment with native LDL (nLDL) or vehicle. Tissue lysates of mouse carotid arteries revealed that cLDL induced the expression of TF, PAI-1, and LOX-1 mRNA in vascular cells. In human aortic smooth muscle and endothelial cells, cLDL induced TF and PAI-1 expression. In contrast, nLDL had no effect on either cell type. While nLDL and cLDL had no aggregatory effect on resting platelets, cLDL enhanced platelet aggregation in response to different agonists. This effect was mediated by mitogen-activated protein kinase p38 phosphorylation and LOX-1 translocation to the surface. LDL isolated from patients with CKD mimicked the prothrombotic effects of cLDL on vascular cells, platelets, and thrombus formation in vivo. CONCLUSIONS: We found that cLDL induces prothrombotic effects in vascular cells and platelets by activation of the LOX-1 receptor and enhances thrombus formation in vivo. This observation reveals a new mechanism underlying the increased incidence of acute thrombotic events observed in patients with CKD and may lead to the development of new lipid-targeting therapies in this population. PMID- 27712776 TI - Late Outcomes of Transcatheter Aortic Valve Replacement in High-Risk Patients: The FRANCE-2 Registry. AB - BACKGROUND: Transcatheter aortic valve replacement (TAVR) has revolutionized management of high-risk patients with severe aortic stenosis. However, survival and the incidence of severe complications have been assessed in relatively small populations and/or with limited follow-up. OBJECTIVES: This report details late clinical outcome and its determinants in the FRANCE-2 (FRench Aortic National CoreValve and Edwards) registry. METHODS: The FRANCE-2 registry prospectively included all TAVRs performed in France. Follow-up was scheduled at 30 days, at 6 months, and annually from 1 to 5 years. Standardized VARC (Valve Academic Research Consortium) outcome definitions were used. RESULTS: A total of 4,201 patients were enrolled between January 2010 and January 2012 in 34 centers. Approaches were transarterial (transfemoral 73%, transapical 18%, subclavian 6%, and transaortic or transcarotid 3%) or, in 18% of patients, transapical. Median follow-up was 3.8 years. Vital status was available for 97.2% of patients at 3 years. The 3-year all-cause mortality was 42.0% and cardiovascular mortality was 17.5%. In a multivariate model, predictors of 3-year all-cause mortality were male sex (p < 0.001), low body mass index, (p < 0.001), atrial fibrillation (p < 0.001), dialysis (p < 0.001), New York Heart Association functional class III or IV (p < 0.001), higher logistic EuroSCORE (p < 0.001), transapical or subclavian approach (p < 0.001 for both vs. transfemoral approach), need for permanent pacemaker implantation (p = 0.02), and post-implant periprosthetic aortic regurgitation grade >=2 of 4 (p < 0.001). Severe events according to VARC criteria occurred mainly during the first month and subsequently in <2% of patients/year. Mean gradient, valve area, and residual aortic regurgitation were stable during follow-up. CONCLUSIONS: The FRANCE-2 registry represents the largest database available on late results of TAVR. Late mortality is largely related to noncardiac causes. Incidence rates of severe events are low after the first month. Valve performance remains stable over time.

AB - As the burden of cardiovascular disease in the United States continues to increase, uncertainty remains on how well-equipped the cardiovascular workforce is to meet the challenges that lie ahead. In a time when health care is rapidly shifting, numerous factors affect the supply and demand of the cardiovascular workforce. This Council Commentary critically examines several factors that influence the cardiovascular workforce. These include current workforce demographics and projections, evolving health care and practice environments, and the increasing burden of cardiovascular disease. Finally, we propose 3 strategies to optimize the workforce. These focus on cardiovascular disease prevention, the effective utilization of the cardiovascular care team, and alterations to the training pathway for cardiologists. PMID- 27712783 TI - Refining Statin Prescribing in Lower-Risk Individuals: Informing Risk/Benefit Decisions. AB - Guidelines from the American College of Cardiology/American Heart Association, as well as those from the Veterans Affairs/Department of Defense and the Joint British Societies all recommended treating more people with statins than previous guidelines. In each guideline, the decision-making process began with an assessment of overall cardiovascular risk. Each group proposed updated treatment thresholds, and all of them lowered the threshold compared with earlier guidelines. Since release of these new guidelines in 2013 and 2014, additional evidence has emerged to suggest a rationale for extending statin consideration to an even larger proportion of asymptomatic adults-even those with a 10-year atherosclerotic cardiovascular disease risk below 7.5%. This review discusses new findings since 2013 and proposes strategies emanating from the current guidelines to help clinicians and patients make more informed decisions about long-term statin use, especially pertinent to lower-risk patients.

AB - In adults, the most common expansile "mass" lesion in the posterior fossa is a subacute stroke, whereas the most common neoplastic lesion in the posterior fossa is cerebellar metastasis (intra-axial) or vestibular schwannoma (extra-axial). Those diseases fall outside the scope of this article, which focuses on primary intra-axial tumors of the posterior fossa in adults. This category of tumors is uncommon and more frequently encountered in children. This article reviews tumors of the cerebellum, brainstem, and fourth ventricle that are seen in adult patients, following categories from the 2007 World Health Organization classification of central nervous system tumors. PMID- 27712792 TI - Lymphomas-Part 1. AB - Primary central nervous system lymphomas are aggressive, high-cell-density tumors. There is recent increase in their incidence in immunocompetent patients. Knowledge of imaging findings on computed tomography and conventional MR imaging is important to suggest the diagnosis. Moreover, information obtained from advanced MR imaging techniques, such as diffusion-weighted imaging, diffusion tensor imaging, MR spectroscopy, perfusion-weighted imaging, and dynamic contrast enhanced studies, increases diagnostic confidence and helps distinguish them from other aggressive intracranial tumors. This article discusses typical imaging findings of primary and secondary central nervous system lymphomas on computed tomography and conventional MR imaging, advanced MR imaging techniques, and changes related to steroid therapy. PMID- 27712793 TI - Lymphomas-Part 2. AB - There are 2 types of central nervous system lymphoma: primary and secondary. Both have variable imaging features making them diagnostic challenges. Furthermore, a patient's immune status significantly alters the imaging findings. Familiarity with typical appearances, variations, and common mimics aids radiologists in appropriately considering lymphoma in the differential diagnosis. Moreover, special types of lymphoma, such as lymphomatosis cerebri, intravascular lymphoma, and lymphomatoid granulomatosis, also are found. This article discusses uncommon types of lymphoma and the differential diagnosis for focal, multifocal, meningeal, and infiltrative lymphomas. PMID- 27712794 TI - Pretreatment Evaluation of Glioma. AB - Glioma is considered the most common type of primary central nervous system (CNS) tumor. Imaging is crucial for diagnosis, characterization, grading, and therapeutic planning of CNS gliomas. Along with a brief description of conventional computed tomography and magnetic resonance imaging techniques, this article reviews the ever-developing role of modern imaging techniques in preoperative management of CNS gliomas. It discusses current clinical applications, promising features, and limitations of each imaging method. PMID- 27712795 TI - Posttreatment Evaluation of Brain Gliomas. AB - The imaging of treated gliomas is complicated by a variety of treatment related effects, which can falsely simulate disease improvement or progression. Distinguishing between disease progression and treatment effects is difficult with standard MR imaging pulse sequences and added specificity can be gained by the addition of advanced imaging techniques. PMID- 27712796 TI - Metastasis in Adult Brain Tumors. AB - Metastatic cancer to the central nervous system is primarily deposited by hematogenous spread in various anatomically distinct regions: calvarial, pachymeningeal, leptomeningeal, and brain parenchyma. A patient's overall clinical status and the information needed to make treatment decisions are the primary considerations in initial imaging modality selection. Contrast-enhanced MR imaging is the preferred imaging modality. Morphologic MR imaging is limited to delineating anatomic deraignment of tissues. Dynamic susceptibility contrast enhanced perfusion and diffusion-weighted physiology-based MR imaging sequences have been developed that complement morphologic MR imaging by providing additional diagnostic information.

All cases of orofacial clefts have an underlying genetic cause, ranging from multifactorial with an underlying genetic predisposition to chromosomal and single-gene etiologies. More than 50% of cases of Pierre Robin sequence are syndromic and 25% of craniosynostoses are syndromic. Clinical genetics evaluation is important for each patient with a craniofacial condition to make a proper diagnosis, counsel the family, and assist in management. This is an overview of the major components of the clinical genetics evaluation with a review of many syndromes associated with craniofacial disorders. PMID- 27712810 TI - Early Airway Intervention for Craniofacial Anomalies. AB - This article reviews the presentation of children with craniofacial anomalies by the most common sites of airway obstruction. Major craniofacial anomalies may be categorized into those with midface hypoplasia, mandible hypoplasia, combined midface and mandible hypoplasia, and midline deformities. Algorithms of airway interventions are provided to guide the initial management of these complex patients. PMID- 27712811 TI - Feeding Management in Infants with Craniofacial Anomalies. AB - The instinctual drive to gain nourishment can become complicated by structural differences, physiologic instability and environmental influences. Infants with craniofacial anomalies may experience significant feeding and swallowing difficulties related to the type and severity of the anomalies present as well as social-emotional interactions with caregivers. Typical outcome measures and feeding goals are discussed. Details regarding clinical and instrumental evaluation, including fiberoptic endoscopic evaluation of swallowing and modified barium swallow study, as well as management techniques are reported. PMID- 27712812 TI - Evaluation of Speech and Resonance for Children with Craniofacial Anomalies. AB - Children with craniofacial anomalies often demonstrate disorders of speech and/or resonance. Anomalies that affect speech and resonance are most commonly caused by clefts of the primary palate and secondary palate. This article discusses how speech-language pathologists evaluate the effects of dental and occlusal anomalies on speech production and the effects of velopharyngeal insufficiency on speech sound production and resonance. How to estimate the size of a velopharyngeal opening based on speech characteristics is illustrated. Nasometry, nasopharyngoscopy, and low-tech tools are discussed as adjunct methods to aid in the evaluation, treatment planning, and measurement of outcomes. PMID- 27712813 TI - Cleft Lip Repair, Nasoalveolar Molding, and Primary Cleft Rhinoplasty. AB - Cleft lip and palate are the fourth most common congenital birth defect. Management requires multidisciplinary care owing to the complexity of these clefts on midface growth, dentition, Eustachian tube function, and lip and nasal cosmesis. Repair requires planning, but can be performed systematically to reduce variability of outcomes. The use of primary rhinoplasty at the time of cleft lip repair can improve nose symmetry and reduce nasal deformity. Use of nasoalveolar molding ranging from lip taping to the use of preoperative infant orthopedics has played an important role in improving functional and cosmetic results of cleft lip repair. PMID- 27712814 TI - Cleft Palate Repair, Gingivoperiosteoplasty, and Alveolar Bone Grafting. AB - Repair of the cleft palate intends to establish the division between the oral and nasal cavity, thereby improving feeding, speech, and eustachian tube dysfunction all while minimizing the negative impact on maxillary growth. Before palate repair candidacy, timing and surgical method of repair is dependent on comorbid conditions, particularly cardiac disease, mandibular length, and palate width. Additionally, management of the alveolar cleft and the indications for gingivoperiosteoplasty versus secondary alveolar bone grafting is a controversial topic that weighs the risks and benefits of potentially sparing the patient an additional surgery against iatrogenic restriction of facial growth and malocclusion.

AB - Velopharyngeal dysfunction (VPD) can significantly impair a child's quality of life and may have lasting consequences if inadequately treated. This article reviews the work-up and management options for patients with VPD. An accurate perceptual speech analysis, nasometry, and nasal endoscopy are helpful to appropriately evaluate patients with VPD. Treatment options include nonsurgical management with speech therapy or a speech bulb and surgical approaches including double-opposing Z-plasty, sphincter pharyngoplasty, pharyngeal flap, or posterior wall augmentation. PMID- 27712816 TI - Intermediate and Definitive Cleft Rhinoplasty. AB - Intermediate and definitive cleft rhinoplasties are a challenging part of definitive cleft care. The anatomy of the cleft nose is severely affected by the structural deficits associated with congenital orofacial clefting. A comprehensive understanding of the related anatomy is crucial for understanding how to improve the appearance and function in patients with secondary cleft nasal deformities. Timing of intermediate and definitive rhinoplasty should be carefully considered. A thorough understanding of advanced rhinoplasty techniques is an important part of providing adequate care for patients with these deformities.

Detailed discussion is presented regarding indications for surgical intervention and management options, including frontoorbital advancement, cranial vault reconstruction, endoscopic strip craniectomy, spring-assisted strip craniectomy, and cranial vault distraction osteogenesis. Deformational plagiocephaly is also presented with treatment options including repositioning, physical therapy, and helmet therapy. PMID- 27712817 TI - Craniofacial Microsomia. AB - Craniofacial microsomia (CFM) encompasses a broad spectrum of phenotypes. It is thought to result from defective development of the first and second pharyngeal arch structures, and generally presents with anomalies of the mandible and other facial bones, ears, and overlying soft tissues. The cause of CFM is thought to involve both extrinsic and genetic risk factors. Several classification systems have been developed to help stratify patients based on the severity of their defects. Treatment of patients includes repair of bony asymmetry as well as soft tissue defects and auricular anomalies. Surgical intervention is individualized based on each patient's deficits. PMID- 27712819 TI - Syndromic Craniosynostosis. AB - Syndromic craniosynostosis affects up to 1:30,000 live births with characteristic craniofacial growth restrictions, deformities, and other associated abnormalities, such as carpal-pedal anomalies and cognitive function impairment. More than 150 syndromes are associated with craniosynostosis. This article describes some commonalities and distinguishing features and management of syndromic synostosis. Also addressed is secondary synostosis, which is often found in syndromic children with problems related to microcephaly, hydrocephalus, or shunt-induced craniosynostosis, although pathophysiologically and genetically different. The importance of obtaining a thorough history and a complete physical and examination is highlighted. Adjuvant testing and multidisciplinary management are discussed.

PMID- 27712822 TI - Facial Nerve Rehabilitation. AB - Facial nerve paralysis, although uncommon in the pediatric population, occurs from several causes, including congenital deformities, infection, trauma, and neoplasms. Similar to the adult population, management of facial nerve disorders in children includes treatment for eye exposure, nasal obstruction/deviation, smile asymmetry, drooling, lack of labial function, and synkinesis. Free tissue transfer dynamic restoration is the preferred method for smile restoration in this population, with outcomes exceeding those of similar procedures in adults. PMID- 27712821 TI - Vascular Lesions. AB - Classification of vascular lesions based of off the biological behavior has greatly facilitated more accurate diagnoses, optimally defined treatment plans, and better outcomes. Treatment of vascular lesions has taken a more conservative surgical approach with reliance on select medical treatment options, which has greatly reduced morbidity and mortality resulting from extensive surgery. A multidisciplinary approach involving multiple surgical and pediatric subspecialties has led to advancement in both understanding and ideal treatment strategies of these lesions. PMID- 27712823 TI - Microtia Reconstruction. AB - Microtia reconstruction is a challenging endeavor that has seen significant technique evolution. It is important to educate patients and their families to determine the best hearing rehabilitation and ear reconstructive options. Microtia is often associated with aural atresia, hearing loss, and craniofacial syndromes. Optimal care is provided by multiple disciplines, including a reconstructive surgeon, an otologic surgeon, an audiologist, and a craniofacial pediatrician. Microtia management includes observation, prosthetic ear, autologous cartilage reconstruction, or alloplastic implant placement. Hearing management options are observation, bone conduction sound processor, or atresiaplasty with and without hearing aids. Appropriate counseling should be done to manage expectations.

With injuries varying widely, the clinical benefits of antibiotics use in facial fracture treatment are not easily determined. The pediatric population is more predisposed to craniofacial trauma secondary to their increased cranial mass to body ratio. All patients with traumatic injury should be assessed according to the Advanced Trauma Life Support protocol. This article discusses the types and prevalence of injuries and approaches to management.

Until the last few decades, rehabilitation was typically prosthesis based with a limited role for surgery. The advent of microsurgical techniques allowed large-volume tissue reconstitution from a distant donor site, revolutionizing the potential approaches to these defects. The authors report a novel surgery-based algorithm and a classification scheme for complete midface reconstruction with a foundation in the Gillies principles of like-to-like reconstruction and with a significant role of computer aided virtual planning. With this approach, the authors have been able to achieve significantly better patient outcomes. PMID- 27712826 TI - Craniofacial Surgery for the Facial Plastic Surgeon. PMID- 27712827 TI - Are Filopodia Privileged Signaling Structures in Migrating Cells? AB - Filopodia are thin, fingerlike structures that contain bundled actin filaments and project from the cell periphery. These structures are dogmatically endowed with the ability to sense cues in the microenvironment, implying that filopodia foster local signal transduction, yet their small diameter hampers the imaging of dynamic processes therein. To overcome this challenge, we analyzed total internal reflection fluorescence images of migrating fibroblasts coexpressing either a plasma membrane marker or tagged AktPH domain, a translocation biosensor for signaling through the phosphoinositide 3-kinase pathway, along with a cytosolic volume marker. We devised a scheme to estimate the radii of filopodia using either the membrane marker or volume marker data, and we used that information to account for geometry effects in the biosensor data. With conservative estimates of relative target molecule abundance, it is revealed that filopodia typically harbor higher densities of 3' phosphoinositides than adjacent regions at the cell periphery. In this context at least, the analysis supports the filopodial signaling hypothesis. PMID- 27712828 TI - Sperm morphometry and chromatin condensation in Nelore bulls of different ages and their effects on IVF. AB - The aim of this study was to evaluate the chromatin packing and sperm head morphometry of cryopreserved semen of Nelore bulls (Bos taurus indicus) of different ages. Furthermore, the influence of the degree of chromatin compaction on in vitro embryo production (IVP) was investigated. Forty bulls were divided into three groups: young (1.8-2 years), adult (3.5-7 years), and senile (8-14.3 years). The ejaculates were frozen according to standards established by the Artificial Insemination Center located in the Southeast of Brazil. Toluidine blue staining was used for simultaneous evaluation of the sperm chromatin and sperm head morphometry. Chromomycin A3 (CMA3) was applied to analyze sperm protamination and IVP for embryonic development. Spermatozoa of young bulls presented higher values for area (A, pixels), perimeter (P, pixels), and width (W, pixels) compared to adults and senile (young: A = 1848.5 +/- 119.79, P = 10.23 +/- 0.29, and W = 1.95 +/- 0.1; adults: A = 1672.9 +/- 104.46, P = 9.86 +/- 0.33, and W = 1.81 +/- 0.06; senile: A = 1723.1 +/- 124.41, P = 9.97 +/- 0.33, and W = 1.83 +/- 0.09; P < 0.0001) and showed higher protamination deficiency when analyzed by CMA3 (young: 1.57 +/- 0.76; adults: 1.09 +/- 0.63, and senile: 0.90 +/- 0.59; P < 0.05). Likewise, variables of sperm head size (A, P, and W) and protamination assessed by CMA3 showed negative correlation with age and positive correlation with ellipticity, evaluated by toluidine blue method (P < 0.05). Sperm head area was larger in spermatozoa presenting chromatin instabilities than spermatozoa without chromatin alteration (P < 0.0001). There was no difference in IVP when using semen with larger or smaller portions of spermatozoa with chromatin instabilities, indicating that the proportion of sperm with abnormal chromatin compaction (4%-16.15%) did not interfere with early embryonic development. From our results, it can be concluded that sperm of young Nelore bulls have larger heads compared to adults and senile due to reduced protamine content when evaluated by CMA3 and higher proportion of major sperm defects assessed by differential interference contrast microscopy.

PMID- 27712830 TI - Parsing Heterogeneity in the Brain Connectivity of Depressed and Healthy Adults During Positive Mood. AB - BACKGROUND: There is well-known heterogeneity in affective mechanisms in depression that may extend to positive affect. We used data-driven parsing of neural connectivity to reveal subgroups present across depressed and healthy individuals during positive processing, informing targets for mechanistic intervention. METHODS: Ninety-two individuals (68 depressed patients, 24 never depressed control subjects) completed a sustained positive mood induction during functional magnetic resonance imaging. Directed functional connectivity paths within a depression-relevant network were characterized using Group Iterative Multiple Model Estimation (GIMME), a method shown to accurately recover the direction and presence of connectivity paths in individual participants. During model selection, individuals were clustered using community detection on neural connectivity estimates. Subgroups were externally tested across multiple levels of analysis. RESULTS: Two connectivity-based subgroups emerged: subgroup A, characterized by weaker connectivity overall, and subgroup B, exhibiting hyperconnectivity (relative to subgroup A), particularly among ventral affective regions. Subgroup predicted diagnostic status (subgroup B contained 81% of patients; 50% of control subjects; chi2 = 8.6, p = .003) and default mode network connectivity during a separate resting-state task. Among patients, subgroup B members had higher self-reported symptoms, lower sustained positive mood during the induction, and higher negative bias on a reaction-time task. Symptom-based depression subgroups did not predict these external variables. CONCLUSIONS: Neural connectivity-based categorization travels with diagnostic category and is clinically predictive, but not clinically deterministic. Both patients and control subjects showed heterogeneous, and overlapping, profiles. The larger and more severely affected patient subgroup was characterized by ventrally driven hyperconnectivity during positive processing. Data-driven parsing suggests heterogeneous substrates of depression and possible resilience in control subjects in spite of biological overlap.

AB - BACKGROUND: Hospitalized adults with fever and "pneumonia" can be a difficult diagnostic challenge particularly when the clinical findings may be due to different infectious diseases. METHODS: We recently had an elderly female who presented with fever, fatigue and dry cough with elevated serum transaminases and lung infiltrates. The diagnosis of Epstein-Barr virus (EBV) infectious mononucleosis (IM) was made based on a positive Monospot test, elevated EBV VCA IgM titer, and highly elevated EBV viral load. Her chest infiltrates were not accompanied by hilar adenopathy which may occur with EBV IM. Her dry cough persisted and she developed abdominal pain. RESULTS: Legionnaire's disease was considered because she had extra-pulmonary findings characteristic of Legionnaire's disease, e.g., relative bradycardia, abdominal pain, hyponatremia, hypophosphatemia, elevated ferritin levels, microscopic hematuria. Legionella titers were negative, but Legionella (serogroup 1) urinary antigen was positive. CONCLUSIONS: We present a diagnostic dilemma in an elderly female with both Legionnaire's disease and Epstein-Barr virus infectious mononucleosis with pulmonary involvement.

PMID- 27712835 TI - Utility of 18 fludeoxyglucose in preoperative positon-emission tomography computed tomography (PET-CT) in the early diagnosis of exocrine pancreatic cancer: A study of 139 resected cases. AB - INTRODUCTION: In pancreatic ductal adenocarcinoma (PDA), surgical resection is the only curative treatment, but due to its late clinical presentation only 15 25% patients are candidates for curative resection. The aim of this prospective, single-center study is to determine the diagnostic utility of preoperative PET-CT for early detection of PDA and early panIN lesions. METHODS: We studied the histopathological features of PDA and different panIN lesions in 139 surgical samples from patients undergoing pancreatic resection (from 2010-2014), comparing these results with preoperative PET-CT and MDCT study. For tumor diagnosis in PET CT maximum standard SUV 2.5 was used. Pancreatic baseline SUVmax is the maximum uptake of the radiotracer 18-2FDG on the ROI curve determined for the area of the normal pancreas after pathological reassessment with areas not affected by tumours or preneoplastic lesions. Tumour Uptake Index is the ratio between the tumour SUVmax and pancreatic baseline SUVmax. RESULTS: Using an standard maximum SUV value of 2.5, PET-CT sensitivity was 77.7% (108 of the 139 cases) against 75.5% (105 of the 139 cases) of MDCT. But when we combined this value with maximum SUV of normal pancreatic tissue from each patient, PET-CT sensitivity improved its value to 94.9%. CONCLUSION: A combination of studies of PET-CT in tumor and non-tumor tissue of each patient might be a very useful diagnostic tool not only for preoperative diagnosis of PDA, but also for early panIN lesions.

AB - BACKGROUND: The poor air quality and cigarette smoking are the most important reasons for increased carbon monoxide (CO) level in exhaled air. However, the influence of high air pollution concentration in big cities on the exhaled CO level has not been well studied yet. OBJECTIVES: To evaluate the impact of smoking habit and air pollution in the place of living on the level of CO in exhaled air. METHODS: Citizens from two large cities and one small town in Poland were asked to complete a survey disclosing their place of residence, education level, work status and smoking habits. Subsequently, the CO level in their exhaled air was measured. Air quality data, obtained from the Regional Inspectorates of Environmental Protection, revealed the differences in atmospheric CO concentration between locations. RESULTS: 1226 subjects were divided into 4 groups based on their declared smoking status and place of living. The average CO level in exhaled air was significantly higher in smokers than in non-smokers (p<0.0001) as well as in non-smokers from big cities than non-smokers from small ones (p<0.0001). Created model showed that non-smokers from big cities have odds ratio of 125.3 for exceeding CO cutoff level of 4ppm compared to non smokers from small towns. CONCLUSIONS: The average CO level in exhaled air is significantly higher in smokers than non-smokers. Among non-smokers, the average exhaled CO level is significantly higher in big city than small town citizens. These results suggest that permanent exposure to an increased concentration of air pollution and cigarette smoking affect the level of exhaled CO. PMID- 27712839 TI - ? PMID- 27712840 TI - Development and psychometric testing of a measure of older adult patients' attitudes towards mobility during hospitalization (ATM-H). AB - This paper describes the development and psychometric testing of a questionnaire evaluating attitudes towards mobility during hospitalization of older adults, an understudied phenomenon that lacks a valid and reliable measure. An instrument development procedure, followed by an empirical study, was conducted between December 2013 and June 2014. Instrument development included item generation and analysis of content validity, which was established by six experts. The validation study used a prospective within-patients design with a sample of 100 patients, age 70+, hospitalized in general medical units in a large medical center. Internal consistency, reliability, and divergent and predictive validity of the measure were tested. Reliability analysis revealed an acceptable estimate for the total score (0.76). Predictive validity was good. The divergent validity coefficient was in the expected direction. Preliminary psychometric properties of the measure showed acceptable results. The measure should be explored further in different cultural settings. PMID- 27712841 TI - Frailty defined by the SHARE Frailty Instrument and adverse outcomes after an ED visit.

PMID- 27712844 TI - Prenatal versus Postnatal Screening for Familial Retinoblastoma. AB - PURPOSE: To compare overall outcomes of conventional postnatal screening of familial retinoblastoma and prenatal RB1 mutation identification followed by planned early-term delivery. DESIGN: Retrospective, observational study. PARTICIPANTS: Twenty children with familial retinoblastoma born between 1996 and 2014 and examined within 1 week of birth. METHODS: Cohort 1 included spontaneously delivered neonates examined within 1 week of birth and confirmed postnatal to carry their family's RB1 mutant allele. Cohort 2 included infants identified by amniocentesis to carry their family's RB1 mutant allele, and therefore scheduled for early-term delivery (36-38 weeks' gestation). Treatment for retinoblastoma was performed at the Hospital for Sick Children, Toronto, Canada. MAIN OUTCOME MEASURES: Age at first tumor in each eye, eye stage, treatments given, ocular salvage, treatment success (defined as avoidance of enucleation, external-beam irradiation, or both), visual outcome, number of anesthetics, pregnancy or delivery complications, and estimated treatment burden. RESULTS: Vision-threatening tumors were present at birth in 4 of 8 infants in cohort 1 and in 3 of 12 infants in cohort 2. Eventually, all infants demonstrated tumors in both eyes. At the first treatment, 1 of 8 infants in cohort 1 had eyes in stage cT1a/cT1a or cT1a/cT0 (smallest and least vision-threatening tumors), compared with 8 of 12 infants in cohort 2 (P = 0.02). Null RB1 germline alleles induced earlier tumors than low-penetrance alleles (P = 0.03). Treatment success was achieved in 3 of 8 children in cohort 1 compared with 11 of 12 children in cohort 2 (P = 0.002). Acceptable vision (better than 0.2 decimal) was achieved for 8 of 16 eyes in cohort 1 compared with 21 of 24 eyes in cohort 2 (P = 0.014). Useful vision (better than 0.1, legal blindness) was achieved for 8 of 9 children in cohort 1 compared with 12 of 12 children in cohort 2. There were no complications related to early-term delivery. Median follow-up was 5.6 years, cohort 1 and 5.8 years, cohort 2. CONCLUSIONS: When a parent had retinoblastoma, prenatal molecular diagnosis with early-term delivery increased the likelihood of infants born with no detectable tumors, better vision outcomes, and less invasive therapy. Prenatal molecular diagnosis facilitates anticipatory planning for both the child and family. PMID- 27712846 TI - Methylation of the circadian Clock gene in the offspring of a free-living passerine bird increases with maternal and individual exposure to PM10. AB - The consequences of exposure to particulate matter (PM) have been thoroughly investigated in humans and other model species, but there is a dearth of studies of the effects of PM on physiology and life-history traits of non-human organisms living in natural or semi-natural environments. Besides toxicological relevance, PM has been recently suggested to exert epigenetic effects by altering DNA methylation patterns. Here, we investigated for the first time the association between the exposure to free-air PM10 and DNA methylation at two loci ('poly-Q exon' and '5'-UTR') of the Clock gene in blood cells of the nestlings of a synanthropic passerine bird, the barn swallow (Hirundo rustica). The Clock gene is a phylogenetically highly conserved gene playing a major role in governing circadian rhythms and circannual life cycles of animals, implying that change in its level of methylation can impact on important fitness traits. We found that methylation at both loci significantly increased with PM10 levels recorded few days before blood sampling, and also with PM10 exposure experienced by the mother during or shortly before egg laying. This study is the first where methylation at a functionally important gene has been shown to vary according to the concentration of anthropogenic pollutants in any animal species in the wild. Since early-life environmental conditions produce epigenetic effects that can transgenerationally be transmitted, DNA methylation of genes controlling photoperiodic response can have far reaching consequences for the ecology and the evolution of wild animal populations.

Cigarette smoking persists in part because long-term smoking cessation rates are modest on existing treatments. Smoking cessation outcomes are influenced by genetic factors, including genetic variation in enzymes that metabolize nicotine and smoking cessation medications, as well as in receptor targets for nicotine and treatment medications. For example, smokers with genetically slow nicotine metabolism have higher cessation success on behavioural counseling and nicotine patches compared with smokers with genetically fast nicotine metabolism. In this review, we highlight new progress in our understanding of how genetic variation in the pharmacological targets of nicotine and smoking cessation medications could be used to tailor smoking cessation therapy, increase quit rates, and reduce tobacco related harm. PMID- 27712849 TI - A safe an easy method for building consensus HIV sequences from 454 massively parallel sequencing data. AB - OBJECTIVE: To show how to generate a consensus sequence from the information of massive parallel sequences data obtained from routine HIV anti-retroviral resistance studies, and that may be suitable for molecular epidemiology studies. MATERIAL AND METHODS: Paired Sanger (Trugene-Siemens) and next-generation sequencing (NGS) (454 GSJunior-Roche) HIV RT and protease sequences from 62 patients were studied. NGS consensus sequences were generated using Mesquite, using 10%, 15%, and 20% thresholds. Molecular evolutionary genetics analysis (MEGA) was used for phylogenetic studies. RESULTS: At a 10% threshold, NGS-Sanger sequences from 17/62 patients were phylogenetically related, with a median bootstrap-value of 88% (IQR83.5-95.5). Association increased to 36/62 sequences, median bootstrap 94% (IQR85.5-98)], using a 15% threshold. Maximum association was at the 20% threshold, with 61/62 sequences associated, and a median bootstrap value of 99% (IQR98-100). CONCLUSION: A safe method is presented to generate consensus sequences from HIV-NGS data at 20% threshold, which will prove useful for molecular epidemiological studies.

PMID- 27712852 TI - Renin-Angiotensin System Blockade and Long-term Clinical Outcomes in Kidney Transplant Recipients: A Meta-analysis of Randomized Controlled Trials. AB - BACKGROUND: Renin-angiotensin system [RAS] blockade has been established as the cornerstone of therapy in the general population, and especially in chronic kidney disease. However, its efficacy in the kidney transplant population remains unknown. STUDY DESIGN: We conducted a systematic review and meta-analysis using MEDLINE (1966 to November 2015), Embase (1980 to November 2015), and the Cochrane Library (third quarter 2015), as well as a PubMed search for recent nonindexed citations. SETTINGS & POPULATION: Adult kidney transplant recipients. SELECTION CRITERIA FOR STUDIES: Randomized controlled trials, with follow-up of 1 year or longer and reporting clinical outcomes of interest. INTERVENTION: RAS blockade (angiotensin-converting enzyme inhibitors or angiotensin receptor blockers) versus placebo, active comparator, or standard of care. OUTCOMES: All-cause mortality, all-cause transplant failure, and doubling of serum creatinine level. RESULTS: 8 trials (1,502 participants) were included in the systematic review. RAS blockade did not significantly alter all-cause mortality (risk ratio [RR], 0.96; 95% CI, 0.62-1.51), transplant failure (RR, 0.76; 95% CI, 0.49-1.18), or creatinine level doubling (RR, 0.84; 95% CI, 0.51-1.39) compared to the control group. This result was robust across the subgroups of interest (angiotensin converting enzyme inhibitor or angiotensin receptor blocker intervention, follow up >= 1 year, and baseline proteinuria as an inclusion criterion). There was significantly higher risk for hyperkalemia with RAS blockade (RR, 2.44; 95% CI, 1.53-3.90). There was no statistical heterogeneity in any of these pooled analyses. LIMITATIONS: Relatively smaller number of events (overall, 71 deaths and 72 transplant failures among 8 trials) and relatively short follow-up (only 2 trials > 5 years). CONCLUSIONS: This analysis neither supports nor refutes the hypothesis that RAS blockade improves clinical outcomes in kidney transplant recipients. A trial with more than 10,000 patients would be needed to definitively answer whether RAS blockade reduces transplant loss in this population. In the meantime, clinicians should weigh the risks and benefits of using these medications with their patients on a case-by-case basis. PMID- 27712853 TI - Commercial vaccines provide limited protection to NADC30-like PRRSV infection. AB - NADC30-like PRRSV has been recently reported and became endemic in vaccinated pig herds in China. The outbreaks of disease in vaccinated pigs indicated the inefficacy of commercial PRRSV vaccines. In this study, five commercial PRRSV vaccines that have been widely used in China were used to evaluate the efficacy to a NADC30-like PRRSV infection. The vaccinated pigs were challenged with HNjz15, a NADC30-like PRRSV at 28days post vaccination. Compared to unvaccinated pigs, the vaccinated pigs clinically shortened the period of fever with less pig numbers of clinical manifestations and had improved body weight gain at the end of the study. However, the vaccinated pigs developed viremia with similar kinetics and suffered pathological lesions in lung and lymphoid tissues as the unvaccinated pigs. The virus load in tonsil, lung and lymph nodes detected by immunohistochemistry staining in vaccinated pigs was also similar to that in unvaccinated pigs which indicated the inability of vaccination to eradicate the virus from tissues of vaccinated pigs. Therefore, the above results suggested current commercial PRRSV vaccines could not provide complete protection to the NADC30-like PRRSV infection. PMID- 27712854 TI - A Hidden Cause of Hemorrhage: Cavernous Venous Malformation. PMID- 27712855 TI - Patient selection does not improve the success rate of infected TKA one stage exchange. AB - BACKGROUND: One stage exchange of a chronically infected total knee arthroplasty (TKA) is recommended in selected cases only. However, there is little evidence regarding the usefulness of selection criteria. The goal of this retrospective study was to compare the results of two concomitant cohorts of patients with chronically infected TKA: one treated with a routine one-stage exchange (study group) and one treated with one-stage exchange in selected cases only (control group). The hypoyhesis tested was that the failure rate and repeat surgery rate were higher in the study group than in the control group. METHODS: One hundred and thirty one cases were selected: 54 in the study group and 77 in the control group. There were 63 men and 68 women with a mean age of 70years. All patients were followed up for a minimal period of time of two years or until death or recurrence of infection. RESULTS: Twenty five cases had a recurrence of infection: 9/54 in the study group and 16/77 in the control group (NS). The survival rate for being free of infection after four years was 85% in the study group and 78% in the control group (NS). The repeat surgery rate was significantly higher in the control group. CONCLUSION: The tested hypothesis was rejected. When one stage exchange is considered, patient selection does not improve outcome. PMID- 27712856 TI - Knee joint position sense ability in elite athletes who have returned to international level play following ACL reconstruction: A cross-sectional study. AB - BACKGROUND: Following an ACL injury, reconstruction (ACL-R) and rehabilitation, athletes may return to play with a proprioceptive deficit. However, literature is lacking to support this hypothesis in elite athletic groups who have returned to international levels of performance. It is possible the potentially heightened proprioceptive ability evidenced in athletes may negate a deficit following injury. The purpose of this study was to consider the effects of ACL injury, reconstruction and rehabilitation on knee joint position sense (JPS) on a group of elite athletes who had returned to international performance. METHODS: Using a cross-sectional design ten elite athletes with ACL-R and ten controls were evaluated. JPS was tested into knee extension and flexion using absolute error scores. Average data with 95% confidence intervals between the reconstructed, contralateral and uninjured control knees were analyzed using t-tests and effect sizes. RESULTS: The reconstructed knee of the injured group demonstrated significantly greater angle of error scores when compared to the contralateral and uninjured control into knee flexion (p=0.0001, r=0.98) and knee extension (p=0.0001, r=0.91). There were no significant differences between the contralateral uninjured knee of the injured group and the uninjured control group. CONCLUSIONS: Elite athletes who have had an ACL injury, reconstruction, rehabilitation and returned to international play demonstrate lower JPS ability compared to control groups. It is unclear if this deficiency affects long-term performance or secondary injury and re-injury problems. In the future physical therapists should monitor athletes longitudinally when they return to play. PMID- 27712857 TI - Removable air-cathode to overcome cathode biofouling in microbial fuel cells. AB - An innovative microbial fuel cell (MFC) design is described, which allows the air cathode to be replaced easily without draining the electrolyte. MFCs equipped with 9-cm2 or 50-cm2 bioanodes provided 0.6 and 0.7W/m2 (referred to the cathode surface area) and were boosted to 1.25 and 1.96W/m2, respectively, when the initial air-cathode was replaced by a new one. These results validate the practical interest of removable air-cathodes and evidence the importance of the cathode biofouling that takes place during the MFC starting phase. As this biofouling is compensated by the concomitant improvement of the bioanodes it cannot be detected on the power curves and may be a widespread cause of performance underestimation. PMID- 27712858 TI - Fine mapping of the GWAS loci identifies SLC35D1 and IL23R as potential risk genes for leprosy. AB - BACKGROUND: Previous genome-wide association study (GWAS) identified two new leprosy associated loci (1p31.3 [rs3762318] and 6q24.3 [rs2275606]). However, there were insufficient validations in independent populations. OBJECTIVE: To validate the association and to map the potentially causal variants/genes underlying the association between the confirmed GWAS hit and leprosy. METHODS: We genotyped 10 variants in the regions encompassing the two loci in 1110 Han Chinese subjects with and without leprosy, followed by expression quantitative trait loci (eQTL), mRNA expression profiling, and network analysis. We further sequenced the exon region of four genes that were located in the confirmed GWAS hit region in 80 leprosy patients and 99 individuals without leprosy. RESULTS: We validated the positive association of rs3762318 with multibacillary leprosy (P=7.5*10-4), whereas the association of rs2275606 could not be validated. eQTL analysis showed that both the GWAS locus rs3762318 and one surrounding positively associated SNP rs2144658 (P=1.8*10-3) significantly affected the mRNA expression of a nearby gene SLC35D1, which might be involved in metabolism. Moreover, SLC35D1 was differentially expressed in skin tissues of leprosy patients, and the differential expression pattern was consistent among leprosy subtypes. Rare damaging missense variants in IL23R were significantly enriched in leprosy patients. CONCLUSION: Our results supported the positive association between the GWAS reported rs3762318 and leprosy, and SLC35D1 and IL23R might be the causal genes. PMID- 27712859 TI - Foeniculum vulgare extract and its constituent, trans-anethole, inhibit UV induced melanogenesis via ORAI1 channel inhibition. AB - BACKGROUND: Ultraviolet radiation exposure is the most important cause of extrinsic skin aging (photoaging), which causes skin wrinkling and hyperpigmentation. Although many factors are involved in the photoaging process, calcium release-activated calcium channel protein 1 (ORAI1) has been reported to be involved in UV-induced melanogenesis. OBJECTIVE: The aim of the present study was to find inhibitory effects of the extract of Foeniculum vulgare (fennel) fruits on ORAI1 ion channels and UV-induced melanogenesis in melanoma cells and to identify its active constituents. METHODS: Active compounds were isolated and quantitatively analyzed. An electrophysiological assay was performed by using the whole-cell patch-clamp technique. Intracellular free calcium concentration was measured by Fura-2. Tyrosinase activity was evaluated by levodopa colorimetry. Effects of the most active compound on cell viability of murine B16F10 melanoma cells and inhibition of melanin content after UVB irradiation were determined. RESULTS: F. vulgare fruits extract and its hexane fraction strongly blocked ORAI1 currents and tyrosinase activity and significantly inhibited UV-induced melanogenesis. Of the 13 compounds isolated from the hexane fraction, trans anethole (TA) exhibited inhibitory effects on ORAI1 (IC50=8.954+/-1.36MUM) and increased cytoplasmic Ca2+ concentrations in response. TA inhibited UV-induced melanogenesis without affecting tyrosinase activity. CONCLUSION: Our findings suggest that the fruits extract of F. vulgare and its active constituent, TA, provide a possible novel approach for treating and preventing UV-induced melanogenesis. PMID- 27712860 TI - A high-resolution operational forecast system for oil spill response in Belfast Lough. AB - This paper presents a high-resolution operational forecast system for providing support to oil spill response in Belfast Lough. The system comprises an operational oceanographic module coupled to an oil spill forecast module that is integrated in a user-friendly web application. The oceanographic module is based on Delft3D model which uses daily boundary conditions and meteorological forcing obtained from COPERNICUS and from the UK Meteorological Office. Downscaled currents and meteorological forecasts are used to provide short-term oil spill fate and trajectory predictions at local scales. Both components of the system are calibrated and validated with observational data, including ADCP data, sea level, temperature and salinity measurements and drifting buoys released in the study area. The transport model is calibrated using a novel methodology to obtain the model coefficients that optimize the numerical simulations. The results obtained show the good performance of the system and its capability for oil spill forecast. PMID- 27712862 TI - Chemogenetic activation of dopamine neurons in the ventral tegmental area, but not substantia nigra, induces hyperactivity in rats. AB - Hyperactivity is a core symptom in various psychiatric disorders, including attention-deficit/hyperactivity disorder, schizophrenia, bipolar disorders, and anorexia nervosa. Although hyperactivity has been linked to dopaminergic signalling, the causal relationship between midbrain dopamine neuronal activity and locomotor hyperactivity remains unknown. In this study, we test whether increased dopamine neuronal activity is sufficient to induce locomotor hyperactivity. To do so, we used designer receptors exclusively activated by designer drugs (DREADD) to chemogenetically enhance neuronal activity in two main midbrain dopamine neuron populations, i.e. the ventral tegmental area (VTA) and substantia nigra pars compacta (SN), in TH:Cre rats. We found that activation of VTA dopamine neurons induced a pronounced and long-lasting hyperactive phenotype, whilst SN dopamine neuron activation only modestly increased home cage locomotion. Furthermore, this hyperactive phenotype was replicated by selective activation of the neuronal pathway from VTA to the nucleus accumbens (NAC). These results show a clear functional difference between neuronal subpopulations in the VTA and SN with regards to inducing locomotor hyperactivity, and suggest that the dopaminergic pathway from VTA to NAC may be a promising target for the treatment of hyperactivity disorders. PMID- 27712861 TI - Occurrence and distribution of bacteria indicators, chemical tracers and pathogenic vibrios in Singapore coastal waters. AB - Water quality in Singapore's coastal area was evaluated with microbial indicators, pathogenic vibrios, chemical tracers and physico-chemical parameters. Sampling sites were grouped into two clusters (coastal sites at (i) northern and (ii) southern part of Singapore). The coastal sites located at northern part of Singapore along the Johor Straits exhibited greater pollution. Principal component analysis revealed that sampling sites at Johor Straits have greater loading on carbamazepine, while turbidity poses greater influence on sampling sites at Singapore Straits. Detection of pathogenic vibrios was also more prominent at Johor Straits than the Singapore Straits. This study examined the spatial variations in Singapore's coastal water quality and provided the baseline information for health risk assessment and future pollution management. PMID- 27712863 TI - Patients' Perceptions and Experiences of Shared Decision-Making in Primary HIV Care Clinics. AB - Shared decision-making (SDM) is considered best practice in health care. Prior studies have explored attitudes and barriers/facilitators to SDM, with few specific to HIV care. We interviewed 53 patients in HIV primary care clinics in California to understand the factors and situations that may promote or hinder engagement in SDM. Studies in other populations have found that patients' knowledge about their diseases and their trust in providers facilitated SDM. We found these features to be more nuanced for HIV. Perceptions of personal agency, knowledge about one's disease, and trust in provider were factors that could work for or against SDM. Overall, we found that participants described few experiences of SDM, especially among those with no comorbidities. Opportunities for SDM in routine HIV care (e.g., determining antiretroviral therapy) may arise infrequently because of treatment advances. These findings yield considerations for adapting SDM to fit the context of HIV care. PMID- 27712864 TI - Mean annual temperatures of mid-latitude regions derived from delta2H values of wood lignin methoxyl groups and its implications for paleoclimate studies. AB - Tree-rings are widely used climate archives providing annual resolutions on centennial to millennial timescales. Stable isotope ratios of tree-rings have been applied to assist with the delineation of climate parameters such as temperature and precipitation. Here, we investigated stable hydrogen isotope ratios (expressed as delta2H values) of lignin methoxyl groups of wood from various tree species collected along a ~3500km north-south transect across Europe with mean annual temperatures (MAT) ranging from -4 to +17 degrees C. We found a strong linear relationship between MATs and delta2H values of wood lignin methoxyl groups. We used this relationship to predict MATs from randomly collected wood samples and found general agreement between predicted and observed MATs for the mid-latitudes on a global scale. Our results are discussed in context of their paleoclimate relevance and suggest that delta2H values of lignin methoxyl groups might have the potential to reconstruct MATs when applied on mid latitudinal tree-ring chronologies of the Late Holocene. PMID- 27712865 TI - Artificial macropores attract crop roots and enhance plant productivity on compacted soils. AB - The structure of compacted soils is characterised by decreased (macro-)porosity, which leads to increased mechanical impedance and decreased fluid transport rates, resulting in reduced root growth and crop productivity. Particularly in soils with high mechanical impedance, macropores can be used by roots as pathways of least resistance. This study investigated how different soil physical states relate to whole plant growth and whether roots grow towards spots with favourable soil physical conditions. Experiments were conducted under controlled and field conditions. Soybean (Glycine max L.), wheat (Triticum aestivum L.) and maize (Zea mays L.) were grown on uncompacted soil, compacted soil and compacted soil with artificial macropores. The interactions between roots and artificial macropores were quantified using X-ray computed tomography. Active growth of roots towards artificial macropores was observed for all three species. Roots grew either into macropores (predominantly in maize) or crossed them (predominantly in wheat). The presence of artificial macropores in compacted soil enabled all three species to compensate for decreased early vigour at later developmental stages. These results show that roots sense their physical environment, enabling them to grow towards spots with favourable soil conditions. The different kinds of root macropore interaction indicated that macropores serve as a path of least resistance and a source of oxygen, both resulting in increased crop productivity on compacted soils. PMID- 27712866 TI - Energy demand for elimination of organic micropollutants in municipal wastewater treatment plants. AB - Organic micropollutants (OMP), e.g. pharmaceuticals and household/industrial chemicals, are not fully eliminated in state-of-the-art municipal wastewater treatment plants and can potentially harm the aquatic environment. Therefore, several pilot and large-scale investigations on the elimination of organic micropollutants have taken place in recent years. Based on the present findings, the most efficient treatment steps to eliminate organic micropollutants have proven to be ozonation, adsorption on powdered activated carbon (PAC), or filtration through granular activated carbon (GAC). Yet a further treatment step implies an increase in energy demand of the wastewater treatment plant, which has to be considered along with OMP elimination. To this aim, data on energy demand of ten large-scale municipal wastewater treatment plants (WWTP) with processes for OMP elimination was collected and analyzed. Moreover, calculations on energy demand beyond the WWTP for production and transport of ancillary materials were performed to assess the cumulative energy demand of the processes. An assessment of the greenhouse gas emissions of the processes was achieved, which shall facilitate future life cycle analyses. The results show that energy demand of ozonation at the wastewater treatment plant is dependent upon the ozone dosage and is significantly higher than energy demand of PAC addition or GAC filtration (2 to 4 times higher without consideration of delivery heads). Despite uncertainties regarding the energy demand for production of activated carbon, it could be shown that the cumulative energy demand of adsorption steps is significantly higher than the energy demand at the WWTP. Using reactivated GAC can lead to energy and greenhouse gas emissions savings compared to using fresh GAC/PAC. Moreover, energy demand is always plant-specific and depends on different factors (delivery heads, existing filtration or post-treatment etc.). Since processes for elimination of organic micropollutants are still in a developing phase, future optimization steps shall minimize their energy demand. PMID- 27712867 TI - The water productivity score (WPS) at global and regional level: Methodology and first results from remote sensing measurements of wheat, rice and maize. AB - Scarce water resources are one of the major constraints to achieve more food production. Food production needs therefore also to be evaluated in terms of water consumption, besides the conventional unit of land. Crop Water Productivity (CWP) is defined as the crop yield per unit of water evaporated. Contrary to crop yield, local benchmark values for CWP do not exist. This paper shows how operational earth observation satellites can measure CWP indirectly on a pixel-by pixel basis, which provides an opportunity to define local, regional and global benchmark values. In analogy to a grading system for earthquakes (Richter) or wind force (Beaufort), a grading system for CWP is introduced: the Water Productivity Score (WPS). A regional scale WPS and a global version - Global Water Productivity Score (GWPS) - are presented. Crop yield zones are used to reflect local production potential, which reflects also the presence of irrigation systems besides general physio-graphical conditions. The 99th percentiles of climatic normalized CWP values at global scale are 2.45, 2.3 and 4.9kgm-3 for wheat, rice and maize respectively. There is significant scope to produce the same - or more - food from less water resources, provided that locally specific best on-farm practices are implemented. At the upstream level, Governments can use (G)WPS to define national water and food policies and use it as a means to report to the Sustainable Development Goal standards. At the downstream level, WPS helps to improve on-farm water management practices by growers, both for rainfed and irrigated crops. While the current paper is based on wheat, rice and maize, the same framework can be expanded to potatoes, sugarbeet, sugarcane, fruit trees, cotton and other crops. PMID- 27712868 TI - Mass, nutrient pool, and mineralization of litter and fine roots in a tropical mountain cloud forest. AB - We used fine root and litter mass from a tropical mountain cloud forest to assess their relative contribution to nutrient content and to examine mineralization processes during a laboratory incubation experiment. Our results showed that average fine root mass density ranged from 2.86kgm-3 to 11.59kgm-3, while litter mass density ranged from 72.5kgm-3 to 177.3kgm-3. On average, fine root mass density represented 4.7% of the mass density of the O horizon. Fine root mass density followed an exponentially declining trend with soil depth. On average, 83% of fine root mass density within the soil profile was concentrated in the O horizon. Mean element pools in litter decreased from 44.08mgcm-3 to 0.49MUgcm-3 in the following sequence: C>N>Fe>S>Ca>P>K>Mg>Na>Mn>Zn>Cu. For fine roots, a different mean element pool sequence (C>N>Ca>K>Fe>S>Mg>Na>P>Mn>Zn>Cu) in decreasing abundance (from 2.88mgcm-3 to 0.13MUgcm-3) was observed with respect to litter. Regarding C, litter mineralized faster than fine roots, with a mean k value of 0.25d-1 for litter and 0.13d-1 for fine roots. Principal component analysis (PCA) combined with stepwise regression analysis revealed that the main mass density predictors were N, S, Zn, and Mn for litter (p<0.0001, R2=0.92), and S and C/N ratio for fine roots (p<0.0001, R2=0.82). These results demonstrate the potential of chemical composition to influence the mineralization of fine root and litter mass and therefore the nutrient availability and C sequestration.

As the main flow contributor to the River Nile, quantifying the effect of LULC change on water resources in the source regions is very important for the assessment of water resources availability and management downstream in the riparian states in general and the study watersheds in particular. In this study, an integrated approach comprising hydrological modeling and partial least squares regression (PLSR) was used to quantify the contributions of changes in individual LULC classes to changes in hydrological components. Two watersheds, namely Lake Tana and Beles in the Upper Blue Nile Basin in Ethiopia, were considered for the conduction of hydrological modeling using LULC maps and the Soil and Water Assessment Tool (SWAT). In the Tana sub-basin, it is found that expansion of cultivation land and decline in woody shrub are the major contributors to the rise in surface run-off and to the decline in the groundwater component. Similarly, decline of woodland and expansion of cultivation land are the major contributors to the increase in surface run-off and water yield in the Beles sub-basin. Increased run-off and reduced baseflow and actual evapotranspiration would have negative impacts on water resources, especially in relation to erosion and sedimentation in the upper Blue Nile River Basin. As a result, expansion of cultivation land and decline in woody shrub/woodland appear to be major environmental stressors affecting local water resources. The wider implications of the hydrological changes on the Easter Nile water resources are briefly discussed. The approach to assessing changes in basin hydrology could generally be applied to a variety of other watersheds for which temporal digital LULC maps are available. PMID- 27712869 TI - Assessing the population equivalent and performance of wastewater treatment through the ratios of pharmaceuticals and personal care products present in a river basin: Application to the River Thames basin, UK. AB - The quality of surface waters in lowland rivers is largely dependent on the efficiency of wastewater treatment. Even in the developed countries, there have been difficulties in evaluating the effectiveness of wastewater management and the proportion of wastewater content (WWC) in the river, as well as in estimating the contributing human population. This study aimed to develop a wastewater quality and quantity assessment based on the occurrence of pharmaceuticals in the receiving waters. A survey of 53 pharmaceuticals in 324 samples (river water and influent and effluent of sewage (wastewater) treatment plants) was carried out in southern England in the River Thames catchment over four years. Carbamazepine was selected as stable marker and from its concentration WWC in the rivers and cumulative human populations along the catchment were estimated. The estimated population had a strong relationship (R2=0.94) with that reported by the local water company. The concentration ratio of the labile marker caffeine to carbamazepine indicated the efficiency of wastewater treatment in the different treatment systems (i.e. trickling filter or activated sludge) and in the receiving waters. The ratio in some river samples revealed unexpected discharges of untreated or poorly treated wastewater, with a total concentration of the analytes (up to 20MUg/L) five times higher than that in treated wastewater. Such information could be valuable to estimate the discharge or occurrence of not only non-targeted chemicals, but also pathogens within the basin. PMID- 27712871 TI - Risk assessment of replacing conventional P fertilizers with biomass ash: Residual effects on plant yield, nutrition, cadmium accumulation and mycorrhizal status. AB - Reutilizing biomass ashes in agriculture can substitute inputs of P from finite primary sources. However, recycling of ashes is disputed due to their content of toxic substances such as heavy metals. This study evaluates the potential risk of replacing easily soluble inorganic P fertilizer with P in biomass ashes in a barley crop grown on soil with adequate P status. Two contrasting doses of three different types of ashes were applied to an agricultural field with spring barley and compared to similar doses of triple-superphosphate fertilizer. In the second growing season after biomass ash application, grain, straw and root dry matter yield, and P and Cd uptake were determined. Resin-extractable P was measured in soil and the symbiotic arbuscular mycorrhizal fungal activity, colonization, and community composition were assessed. Crop yield was not affected by ash application, while P-uptake and mycorrhizal status were slightly enhanced with high ash applications. Changes to the mycorrhizal community composition were evident with high ash doses. Cadmium uptake in aboveground plant tissue was unaffected by ash treatments, but increased in roots with increasing doses. Consequently, we conclude that fertilization with biomass ashes can replace conventional fertilizers without risk to barley crops in the short term. PMID- 27712872 TI - Verification of the oncologic inferiority of percutaneous biliary drainage to endoscopic drainage: A propensity score matching analysis of resectable perihilar cholangiocarcinoma. AB - BACKGROUND: Percutaneous transhepatic biliary drainage is an established biliary drainage method but is associated with a potential risk of seeding metastasis. The aim of this retrospective study was to evaluate whether percutaneous transhepatic biliary drainage really increases seeding metastasis and worsens the postoperative survival in patients with resectable perihilar cholangiocarcinoma. METHODS: Patients who underwent resection for perihilar cholangiocarcinoma after percutaneous transhepatic biliary drainage or endoscopic biliary drainage were retrospectively reviewed. Seeding metastasis was defined as peritoneal/pleural dissemination and percutaneous transhepatic biliary drainage sinus tract recurrence. Univariate and multivariate analyses followed by propensity score matching were performed to adjust the data for the baseline characteristics of the percutaneous transhepatic biliary drainage and endoscopic biliary drainage patients. RESULTS: Of 320 resected patients, 168 underwent percutaneous transhepatic biliary drainage and the remaining 152 received endoscopic biliary drainage before operation. The survival of the percutaneous transhepatic biliary drainage patients was significantly lower than that of the endoscopic biliary drainage patients (37.0% vs 44.3% at 5 years, P = .019). Multivariate analyses showed that percutaneous transhepatic biliary drainage was an independent predictor of poor survival (P = .011) and a risk factor for seeding metastasis (P = .005). After propensity score matching (71 patients in each group), the survival of the percutaneous transhepatic biliary drainage patients was significantly worse than that of the endoscopic biliary drainage patients (P = .018). The estimated cumulative recurrence rate of seeding metastasis was significantly higher in the percutaneous transhepatic biliary drainage patients than in the endoscopic biliary drainage patients (P = .005), while the recurrence rates at other sites were similar between the 2 groups (P = .413). CONCLUSION: Percutaneous transhepatic biliary drainage increases the incidence of seeding metastasis and shortens the postoperative survival in patients with perihilar cholangiocarcinoma. Endoscopic biliary drainage is recommended as the optimal method for preoperative biliary drainage. PMID- 27712873 TI - Impact of different sarcopenia stages on the postoperative outcomes after radical gastrectomy for gastric cancer. AB - BACKGROUND: The association between sarcopenia and postoperative outcomes has been well reported. However, the impact of different sarcopenia stages on postoperative outcomes has never been investigated. METHODS: We conducted a large, prospective study of patients who underwent radical gastrectomy for gastric cancer from August 2014 to December 2015. Sarcopenia was staged as "presarcopenia," "sarcopenia," and "severe sarcopenia" according to the definition of the European Working Group on Sarcopenia in Older People. Univariate and multivariate analyses evaluating the risk factors for total, surgical, and medical complications were performed. RESULTS: A total of 470 patients were included, in which 20.6%, 10%, and 6.8% of the patients were identified as having "presarcopenia," "sarcopenia," and "severe sarcopenia," respectively. Postoperative complications, duration of hospital stays, and costs increased with advancing sarcopenia stages. Severe sarcopenia, visceral fat area to total abdominal muscle area ratio, American Society of Anesthesiologists grade III, and tumor located at the cardia were independent risk factors for total complications. Visceral fat area to total abdominal muscle area ratio and tumor located at the cardia were independent risk factors for operative complications. Presarcopenia, sarcopenia, and severe sarcopenia were all identified as independent risk factors for medical complications, as well as age >=75 years and Charlson Comorbidity Index. CONCLUSION: Patients had worse postoperative outcomes after gastric cancer operation with advancing sarcopenia stages. Severe sarcopenia, but not presarcopenia or sarcopenia, was an independent risk factor for total postoperative complications. The 3 sarcopenia stages independently influence medical but not surgical complications. Recognizing sarcopenia stages is important for preoperative risk stratification. PMID- 27712874 TI - Variability in postoperative resource utilization after pancreaticoduodenectomy: Who is responsible. AB - BACKGROUND: We aimed to quantify and predict variability that exists in resource utilization after pancreaticoduodenectomy and determine how such variability impacts postoperative outcomes. METHODS: The University HealthSystems Consortium database was queried for all pancreaticoduodenectomies performed between 2011 2013 (n = 9,737). A composite resource utilization score was created using z scores of 8 clinically significant postoperative care delivery variables including number of laboratory tests, imaging tests, computed tomographic scans, days on antibiotics, anticoagulation, antiemetics, promotility agents, and total number of blood products transfused per patient. Logistic, Poisson, and gamma regression models were used to determine predictors of increased variability in care between patients. RESULTS: Having a high (versus low) resource utilization score after pancreaticoduodenectomy correlated with increased duration of stay; (odds ratio 2.28), cost (odds ratio 1.89), readmission rate (odds ratio 1.46), and mortality (odds ratio 7.54). Patient-specific factors were the strongest predictors and included extreme severity of illness (odds ratio 114), major comorbidities/complications (odds ratio 5.99), and admission prior to procedure (odds ratio 2.72; all P < .01). Surgeon and center volume were not associated with resource utilization. CONCLUSION: Public reporting of patient outcomes and resource utilization, invariably tied to reimbursement in the near future, should consider that much of the postoperative variability after complex pancreatic operation is related to patient-specific risk factors. PMID- 27712875 TI - Insurance status is associated with complex presentation among emergency general surgery patients. AB - BACKGROUND: The Affordable Care Act has the potential to significantly affect access to care for previously uninsured patients in need of emergency general surgical care. Our objective was to determine the relationship between insurance status and disease complexity at presentation among a national sample of emergency general surgical patients. METHODS: Data from the National Emergency Department Sample from 2006-2009 were queried to identify all patients aged 18-64 years old admitted through the emergency department with a primary diagnosis of appendicitis, diverticulitis, inguinal hernia, or bowel obstruction. Primary outcome of complex presentation was defined as also presenting with generalized peritonitis, intra-abdominal abscess, perforated bowel, intestinal gangrene, or other disease-specific measures of complexity. We used multivariable logistic regression to determine the independent association between insurance status and complex presentation. Models accounted for patient- and hospital-level covariates. Counterfactual models were used to estimate the risk of complex presentation attributable to lack of insurance. RESULTS: A total of 1,373,659 patients were included, with an overall uninsured rate of 12.3%. Uninsured patients had significantly higher, unadjusted rates of complex presentation, and uninsured payer status was independently associated with complex presentation (odds ratio 1.38, 95% confidence interval: 1.34-1.42). Counterfactual models suggest that having insurance would result in a 22.37% (95% confidence interval: 22.35-22.39%) relative decline in risk of complex emergency general surgical presentation among the uninsured population. CONCLUSION: Insurance status is independently associated with severity of disease at presentation among emergency general surgical conditions nationally. In light of recently reaffirmed Affordable Care Act insurance expansion provisions, these results anticipate increased timely access to operative care for newly insured patients and a corresponding decline in complex, emergency general surgical presentations. PMID- 27712876 TI - Allicin ameliorates intraintestinal bacterial translocation after trauma/hemorrhagic shock in rats: The role of mesenteric lymph node dendritic cell. AB - BACKGROUND: Intestinal dendritic cells play important roles in regulating the function of the intestinal immune barrier and the intestinal bacterial translocation. In this study, we aim to investigate the effects of allicin on the function of mesenteric lymph node-dendritic cells after trauma/hemorrhagic shock. METHODS: One hundred and eight-four Sprague-Dawley rats were randomly assigned into a sham group (n = 46), sham + allicin group (n = 46), trauma/hemorrhagic shock group (n = 46), and trauma/hemorrhagic shock + allicin group (n = 46). Studies were performed on an in vivo model of spontaneously breathing rats with induced trauma/hemorrhagic shock. Allicin was diluted in resuscitation fluid and was administered through the right jugular vein. Flow cytometry was used to determine the expression of CD80, CD86, and major histocompatibility complex II (MHC II) on the surface of mesenteric lymph node-dendritic cells, as well as apoptosis. Intraintestinal bacterial translocation was monitored by using bioluminescent citrobacter. Intestinal permeability tests were conducted by using both FITC-Dextran and Ussing-Chember assay. RESULT: CD80 and MHC-II expression levels were downregulated in the trauma/hemorrhagic shock group compared with the sham and sham + allicin groups; however, the expression was upregulated after allicin treatment. Also, allicin could ameliorate the trauma/hemorrhagic shock induced increase in early apoptosis of mesenteric lymph node-dendritic cells. A significant increase was observed in the permeability of the intestinal barrier after severe traumatic shock, along with an obvious intraintestinal bacterial translocation to mesenteric lymph node. No difference was noticed in the bacterial translocation in mesenteric lymph node in the trauma/hemorrhagic shock group compared with trauma/hemorrhagic shock + allicin group (P = .589), which indicated allicin could not block bacterial translocation into mesenteric lymph node after trauma/hemorrhagic shock. However, it may increase the capacity of mesenteric lymph node to block intraintestinal bacterial translocation to extraintestinal organs as a statistical difference was noticed in the bacterial translocation in liver, blood, and spleen between trauma/hemorrhagic shock and trauma/hemorrhagic shock + allicin groups (P < .05). CONCLUSION: Trauma/hemorrhagic shock resulted in a decrease of mature mesenteric lymph node dendritic cells. Allicin treatment could block intraintestinal bacterial translocation through increasing the immunologic barrier function of mesenteric lymph node by modulating dendritic cells maturation. PMID- 27712877 TI - Safety and feasibility of phlebotomy with controlled hypovolemia to minimize blood loss in liver resections. AB - BACKGROUND: Liver resection can be associated with significant blood loss and transfusion. Whole blood phlebotomy is an under-reported technique, distinct from acute normovolemic hemodilution, the goal of which is to minimize blood loss in liver operation. This work sought to report on its safety and feasibility and to describe technical considerations. METHODS: Consecutive patients who had an elective liver resection and concurrent phlebotomy between 2013 and 2016 were examined prospectively. Formal Inclusion and exclusion criteria were defined a priori. All surgical indications were allowed. All procedures were carried out with a stated goal of low central venous pressure anesthesia (<5 cm H2O). The target phlebotomy volume was 7-10 mL/kg of patient body weight. The removed blood was not replaced by intravenous fluid. Removed blood was returned back to the patient after parenchymal transection. Safety end points were examined. A historic cohort (2010-2014) of major resections was included for comparison. RESULTS: A total of 37 patients underwent liver resection with phlebotomy (86% major) and 101 without. Half had metastatic colorectal cancer. The median phlebotomy volume was 7.2 mg/kg (4.7-10.2), yielding a median drop in central venous pressure of 3 cm H2O (0-15). Median blood loss was 400 vs 700 mL (P = .0016), and the perioperative transfusion rate was 8.1% vs 32% (P = .0048). There was no difference between the 2 groups in overall complications, mortality, intensive care admission, duration of stay, or end-organ ischemic complications. CONCLUSION: Whole blood phlebotomy with controlled hypovolemia prior to liver resection seems to be safe and feasible. Comparative studies are required to determine its effectiveness.

PMID- 27712879 TI - Primary hyperparathyroidism with normal baseline intraoperative parathyroid hormone: A challenging population. AB - BACKGROUND: Patients with primary hyperparathyroidism and baseline intraoperative parathyroid hormone levels in the normal range are challenging. This study compares the predictive value of a commonly used intraoperative parathyroid hormone algorithm, a software model for cure prediction, and surgeon judgment in this population. METHODS: This was a retrospective review of consecutive patients who underwent parathyroidectomy for primary hyperparathyroidism at a single institution from March 2013 to October 2014. RESULTS: Of 541 operative patients, 114 (21.1%) had a mean normal baseline intraoperative parathyroid hormone of <=69 pg/mL (median 59.0 +/- 10.3; range 26-69). Of the 114 patients, 93 (81.6%) were women, median age was 61 years (range 18-88). Overall, 107/108 (99.1%) patients were cured; 47 (41.2%) patients had single adenomas, 16 (14%) had double adenomas, and 51 (44.7%) had multigland hyperplasia. Using the 50% decline algorithm, a correct prediction was made in 86 (75.4%) patients. Using the computer software, a correct prediction was made in 88 (77.2%) patients. Surgeon judgment, however, was 99.1% accurate. CONCLUSION: Patients with normal baseline intraoperative parathyroid hormone have a high incidence of multigland disease (58.8%), greater than reported previously. Current software modeling and the 50% decline algorithm are insufficient to predict cure in this population; intraoperative parathyroid hormone interpretation combined with operative findings and surgical judgment yield optimal outcomes. PMID- 27712880 TI - Peritonitis in Rwanda: Epidemiology and risk factors for morbidity and mortality. AB - BACKGROUND: Few studies discuss causes and outcomes of peritonitis in low-income settings. This study describes epidemiology of patients with peritonitis at a Rwandan referral hospital. Identification of risk factors associated with mortality and unplanned reoperation could improve management of peritonitis. METHODS: Data were collected on demographics, clinical presentation, operative findings, and outcomes for all patients with peritonitis. Multivariate regression analysis identified factors associated with in-hospital mortality and unplanned reoperation. RESULTS: A total of 280 patients presented with peritonitis over a 6 month period. Causes of peritonitis were complications of intestinal obstruction (39%) and appendicitis (17%). Thirty-six (13%) patients required unplanned reoperation, and in-hospital mortality was 17%. Factors associated with increased odds of in-hospital mortality were unplanned reoperation (adjusted odds ratio 34.12), vasopressor use (adjusted odds ratio 24.91), abnormal white blood cell count (adjusted odds ratio 12.6), intensive care unit admission (adjusted odds ratio 9.06), and American Society of Anesthesiologist score >=3 (adjusted odds ratio 7.80). Factors associated with increased odds of unplanned reoperation included typhoid perforation (adjusted odds ratio 5.92) and hypoxia on admission (adjusted odds ratio 3.82). CONCLUSION: Peritonitis in Rwanda presents with high morbidity and mortality. Minimizing delays in care is important, as many patients with intestinal obstruction present with features of peritonitis. A better understanding of patient care and management prior to arrival at the referral hospital is needed to identify areas for improvement at the health center and district hospital.

PMID- 27712882 TI - Spatial frequency content of plantar pressure and shear profiles for diabetic and non-diabetic subjects. AB - How high does pressure and shear stress sensor resolution need to be in order to reliably measure the plantar pressure and shear profiles (PPSPs) under normal and diabetic feet? In this study, pressure and shear stress data were collected from 26 total diabetic and control subjects using new instrumentation that measures vertical and horizontal force vectors of the plantar contact surface during multiple instances in the gait cycle. The custom built shear-and-pressure evaluating-camera-system (SPECS) performs simultaneous recordings of pressure and both components of the horizontal force vector (medio-lateral and antero posterior) at distinctive regions under one's foot, at a spatial resolution for each sensor equal to 1.6mm by 1.6mm. A linear interpolation method was used to simulate the effect of increasing sensor size on PPSPs. Ten square-shaped sensors were included in the analysis, having edge lengths of: (1.6mm, 3.2mm, 4.8mm, 6.4mm, 8mm, 9.6mm, 11.2mm, 12.8mm, 14.4mm, and 16mm). A two-dimensional Discrete Fourier Transform was performed on each data set, for each of the ten sensor sizes. To quantify the difference between sensor sizes, a comparison was made using the maximum pressure and shear stress data over the entire plantar contact surface, equivalent to the peak of the spatial frequency spectrum. A reduction of 5% of any component of the stress vector (i.e., pressure, or medio-lateral shear stress, or anter-posterior shear stress) due to an increase in sensor size was deemed significant. The results showed that a sensor measuring 9.6mm by 9.6mm caused meaningful reductions in all three stress components (p<0.001), whereas sensors measuring 1.6mm by 1.6mm, up to 4.8mm by 4.8mm, can capture the full range of spatial frequencies in both pressure and shear stress data. PMID- 27712883 TI - Effects of sex, age, body height and body weight on spinal loads: Sensitivity analyses in a subject-specific trunk musculoskeletal model. AB - Subject-specific parameters influence spinal loads and the risk of back disorders but their relative effects are not well understood. The objective of this study is to investigate the effects of changes in age (35-60 years), sex (male, female), body height (BH: 150-190cm) and body weight (BW: 50-120kg) on spinal loads in a full-factorial simulation using a personalized (spine kinematics, geometry, musculature and passive properties) kinematics driven musculoskeletal trunk finite element model. Segmental weight distribution (magnitude and location along the trunk) was estimated by a novel technique to accurately represent obesity. Five symmetric sagittal loading conditions were considered, and main effect plots and analyses of variance were employed to identify influential parameters. In all 5 tasks simulated, BW (98.9% in compression and 96.1% in shear) had the greatest effect on spinal loads at the L4-L5 and L5-S1 levels followed by sex (0.7% in compression and 2.1% in shear), BH (0.4% in compression and 1.5% in shear) and finally age (<5.4%). At identical BH and BW, spinal loads in females were slightly greater than those in males by ~4.7% in compression and ~8.7% in shear. In tasks with no loads in hands, BW-normalized spinal loads further increased with BW highlighting the exponential increase in spinal loads with BW that indicates the greater risk of back disorders especially in obese individuals. Uneven distribution of weight in obese subjects, with more BW placed at the lower trunk, further (though slightly <7.5%) increased spinal loads. PMID- 27712884 TI - Predicting protein partition coefficients in aqueous two phase system. AB - The present work aims to achieve an additional insight into the protein partitioning behavior in aqueous two phase systems (ATPSs), together with a study on the viability of a semi-empirical model based on continuum electrostatics to predict the protein partition characteristics. The partitioning behaviors of 14 globular proteins, with different properties, were explored in three polymer/polymer ATPSs. By the Collander equation, a linear correlation between protein partitioning coefficients in all systems was observed. Using the semi empirical model it was possible to predict the partitioning behavior of proteins. The electrostatic energy depends on the protein size and ATPSs characteristics and varies in agreement with the difference in phase dielectric constants. Linear correlation of nonpolar energy, and the solvent accessible surface area was observed. Polymer structure and concentration have a significant influence on model viability. A good qualitative prediction of preferred phase for studied proteins was observed. PMID- 27712885 TI - Intelligent peak deconvolution through in-depth study of the data matrix from liquid chromatography coupled with a photo-diode array detector applied to pharmaceutical analysis. AB - Multivariate curve resolution-alternating least squares (MCR-ALS) method was investigated for its potential to accelerate pharmaceutical research and development. The fast and efficient separation of complex mixtures consisting of multiple components, including impurities as well as major drug substances, remains a challenging application for liquid chromatography in the field of pharmaceutical analysis. In this paper we suggest an integrated analysis algorithm functioning on a matrix of data generated from HPLC coupled with photo diode array detector (HPLC-PDA) and consisting of the mathematical program for the developed multivariate curve resolution method using an expectation maximization (EM) algorithm with a bidirectional exponentially modified Gaussian (BEMG) model function as a constraint for chromatograms and numerous PDA spectra aligned with time axis. The algorithm provided less than +/-1.0% error between true and separated peak area values at resolution (Rs) of 0.6 using simulation data for a three-component mixture with an elution order of a/b/c with similarity (a/b)=0.8410, (b/c)=0.9123 and (a/c)=0.9809 of spectra at peak apex. This software concept provides fast and robust separation analysis even when method development efforts fail to achieve complete separation of the target peaks. Additionally, this approach is potentially applicable to peak deconvolution, allowing quantitative analysis of co-eluted compounds having exactly the same molecular weight. This is complementary to the use of LC-MS to perform quantitative analysis on co-eluted compounds using selected ions to differentiate the proportion of response attributable to each compound. PMID- 27712886 TI - Chromatographic behaviour of synthetic high pressure high temperature diamond in aqueous normal phase chromatography. AB - The chromatographic properties of high pressure high temperature synthesised diamond (HPHT) are investigated under the conditions of hydrophilic interaction liquid chromatography (HILIC). A 50*4.6mm ID stainless steel column packed with HPHT particles of mean diameter 1.6MUm and specific surface area 5.1m2g-1 is used. According to the results of acid-base titration with NaOH the purified HPHT batch contains 4.59MUeqg-1 of protogenic, mainly carboxyl- and hydroxyl-, groups, which make this polar adsorbent suitable for use as a stationary phase in HILIC. The retention behaviour of several classes of polar compounds including benzoic and benzenesulfonic acids, nitro- and chlorophenols, various organic bases, and quaternary ammonium compounds are studied using acetonitrile and methanol based mobile phases containing 5-30v/v% of water. The effects of the buffer pH and concentration, column temperature and organic solvent content on retention of model compounds are also investigated. It is shown that both pH and acetonitrile/methanol ratio in the mobile phase can be used to vary the separation selectivity. Molecular adsorption mechanism (related to aqueous normal phase mode), rather than partitioning is established to be responsible for the retention.

PMID- 27712887 TI - Resectability and tumor response after preoperative chemotherapy in hepatoblastoma treated by the Japanese Study Group for Pediatric Liver Tumor (JPLT)-2 protocol. AB - BACKGROUND/PURPOSE: We aimed to clarify whether surgical resectability and tumor response after preoperative chemotherapy (preCTx) represented prognostic factors for patients with hepatoblastoma (HBL) in the JPLT-2 study (1999-2012). METHODS: Patients (N=342) with HBL who underwent preCTx were eligible. PRETEXT, CHIC risk stratification (standard [SR], intermediate [IR] and high risk [HR]) at diagnosis, POST-TEXT, and tumor resectability were evaluated by imaging. Tumor response was classified into responders (CR or PR) and nonresponders (NC or PD) according to RECIST criteria. RESULTS: There were 7 PRETEXT I, 106 II, 143 III, and 86 IV, including 71 metastatic HBLs. In POST-TEXT, 12 PRETEXT II, 42 III, and 58 IV were down-staged. The 5-year EFS/OS rates of 198 SR, 73 IR, and 71 HR-HBLs were 82/94%, 49/64%, and 28/34%, respectively. In 198 SR, 154 of 160 responders and 24 of 38 nonresponders survived event-free (P<0.01). In 73 IR, 12 of 24 whose tumors remained unresectable experienced recurrence, 9 of whom were nonresponders (P<0.01). In 71 HR, chemoresponders and tumor resectability after preCTx correlated with favorable outcomes (P<0.05). CONCLUSIONS: Evaluation of response and tumor resectability after preCTx is useful for predicting prognosis in HBLs. To improve outcomes, we should reconsider surgical procedures according to resectability and chemoresponsiveness. LEVEL OF EVIDENCE: Level II. PMID- 27712890 TI - Acute gastrointestinal compromise in neonates with congenital diaphragmatic hernia prior to repair. AB - BACKGROUND: Congenital diaphragmatic hernia (CDH) affects 1 in 3000 live births. Modern management strategies include delayed repair of the diaphragm to permit pre-operative optimization of cardiorespiratory status. We describe a cohort of neonates in whom early emergency operative intervention was required for potentially fatal intestinal compromise. METHODS: A retrospective review was performed of all neonatal CDH patients managed at a tertiary center in an 8-year period (2005-2012). RESULTS: A total of 126 CDH patients were managed during the 8-year period. Five neonates (male - 1; gestation 37+4-39+7; birth weight 2.9 3.7kg; left CDH - 5) required emergency operative intervention for presumed gastrointestinal compromise. All five neonates demonstrated systemic hypotension despite inotropic support, raised serum lactate (>2mmol/L), and abnormal radiographic findings. Operative intervention occurred within 3days of birth (1 3days). Findings included gastric volvulus, jejunal volvulus, and perforated caecum. All patients underwent primary diaphragmatic repair without a patch. Temporary ileostomy was required in 1 patient. All patients remain alive. CONCLUSION: Gastrointestinal compromise is a rare, but potentially catastrophic, complication of CDH. Emergency operative intervention may be required in a select cohort of patients. Early deterioration following birth should alert clinicians to the possibility of significant intestinal pathology. LEVEL OF EVIDENCE: Level IV case series with no comparison group.

We describe two children with clinical presentations mimicking appendicitis. A correct diagnosis was eventually achieved by magnetic resonance imaging (MRI) and confirmed at laparoscopy in the initial case. Our preliminary experience suggests that MRI is a valid and non-invasive alternative to computed tomography for characterization of unusual causes of pediatric abdominal pain in the acute hospital care setting. PMID- 27712891 TI - Usefulness of posterior sagittal anorectoplasty for redo pull-through in complicated and recurrent Hirschsprung disease: Experience with a single surgical group. AB - AIM: To retrospectively examine 12 patients with Hirschsprung disease (HD) who underwent posterior sagittal anorectoplasty (PSARP) for various complications. METHODS: This study included patients with HD who underwent redo pull-through (PT) via PSARP at our institute between 2005 and 2014. The type of initial procedure, clinical presentations, indications, and functional results were analyzed. Postoperative excretory function was assessed using the Krickenbeck classification. RESULTS: The study group comprised 9 boys and 3 girls (total, 12). Five patients were diagnosed with rectosigmoid aganglionosis, 5 with long segment aganglionosis, and 2 with total colonic aganglionosis. The primary operations performed on these patients included the Soave, Duhamel, Swenson, Rehbein, and Ikeda-Soper procedures. The interval between the primary operations and reoperation ranged from 5months to 8years (median, 3years). The indications for PSARP were rectocutaneous fistulae (6 cases), frozen pelvis (5 cases), severe anastomotic stricture (3 cases), rectovaginal fistulae (2 cases), and hemorrhagic proctitis with an inflammatory polyp (1 case). All fistulae were repaired using PSARP; only one rectocutaneous fistula recurred and required two additional surgeries. Stricture and hemorrhagic proctitis were cured in all involved cases. Nine patients were followed up for 8months to 10years after PSARP surgery (average, 5.1years). All 9 patients had voluntary bowel movements within 6months after the last PSARP and stoma closure: 3 had normal bowel movement, while 6 had varying degrees of soiling, depending on the length of residual colon. None complained of constipation. CONCLUSION: PSARP is useful for treating severe complications of failed PT in HD. Complex and recurrent rectocutaneous fistulae and frozen pelvis are the main indications for PSARP, while soiling is the most common surgical complication.

AB - PURPOSE: Inspissated bile syndrome (IBS) is a rare cause of obstructive jaundice in neonates and infants with several treatment options reported. We present our experience with the use of minimally invasive ultrasound-guided percutaneous cholecystostomy drain catheter placement with ongoing saline lavage in neonates and infants. METHODS: Retrospective chart review of patients treated with percutaneous cholecystostomy, from February 2010 till June 2015. We reviewed the technical and clinical success along with complications of the procedure. RESULTS: There were 6 patients, mean age 17weeks (range 4-40). Most had significant risk factors for IBS presenting with biliary obstruction. A total of 7 procedures performed on the 6 patients, with a technical success rate of 6/7. One patient required cannulation of the intrahepatic biliary system. Drains were flushed for a median of 26days (10-70). Clinical success was achieved in all patients. 3 had displacement of the drain, one of which required re-insertion. Another developed a small sub-hepatic collection post procedure with pyrexia. On long term follow up one was found to have a forme fruste choledochal cyst. CONCLUSION: Centers with suitable interventional radiology services ultrasound guided percutaneous cholecystostomy drain catheter placement with ongoing saline lavage is a safe and effective minimally invasive treatment for IBS in neonates and infants.

AB - The last two years of insulin-like growth factor (IGF) research has yielded a vast literature highlighting the central role IGFs factors play in processes such as development, growth, aging and neurological function. It also provides our latest understanding of how IGF system perturbation is linked to diseases including growth deficiency, cancer, and neurological and cardiovascular diseases. A snapshot of the highlights is presented in this review, focussing on the topics of IGFs and growth, comparative and structural biology to understand insulin-like peptide function, IGFs and cancer, and IGFs and neurological function. New revelations in the IGF field include the unexpected discovery that the gut microbiome has a remarkable influence on the GH/IGF axis to influence growth, that the insulin of cone snails provides novel insight into the mechanism of receptor binding, and that macrophages in the tumour microenvironment can provide IGF-I to promote drug resistance. These advances and many others provide the exciting basis for future development of disease treatments and for biomarkers of disease. PMID- 27712895 TI - Osteochondroma. PMID- 27712896 TI - Choroid Detachment, a Rare Cause of Vision Loss Diagnosed by Point-of-Care Ultrasound. AB - BACKGROUND: Choroid detachment is a rare disease process that has a multitude of etiologies; usually related to recent ophthalmological surgery, eye trauma, corneal ulcers, or intraocular pressure-lowering agents. Point-of-care ocular ultrasound has high utility and accuracy in diagnosing pathology of the eye. CASE REPORT: We present a case of a patient who presented with vision loss caused by a choroid detachment diagnosed on point-of-care ultrasound because fundoscopic examination was limited due to cataracts. Ultrasound findings based on location and appearance during both static and dynamic evaluation that help differentiate a choroid vs. a retinal detachment are also described. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Choroid detachments have a different sonographic appearance, as well as management, compared to a retinal detachment.

AB - BACKGROUND: Epistaxis is a common emergency department (ED) complaint; however, this entity is rare among children younger than 2 years of age. In this age group, epistaxis may be a presenting sign of a bleeding disorder or nonaccidental trauma. CASE REPORT: We present a case of a 2-month-old infant who was evaluated in the pediatric ED for epistaxis and discharged home. The infant returned 2 days later with facial swelling and irritability, and was found to have significant head trauma. In this article we review the epidemiology and differential diagnoses for epistaxis among infants, as well as the initial approach to the evaluation of this uncommon clinical entity in this age group. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Potential etiologies for epistaxis among infants and young children include severe systemic disease and nonaccidental trauma. Given its rarity and possible clinical significance, the approach to epistaxis differs in this age group. Emergency physicians should screen for and exclude a bleeding disorder while also having a very low threshold for a nonaccidental trauma evaluation.

PMID- 27712901 TI - Electronic Cigarette Explosion Resulting in a C1 and C2 Fracture: A Case Report. AB - BACKGROUND: Electronic cigarettes have seen a drastic increase in use. A lithium ion battery is often used as the rechargeable battery of the electronic cigarette device and has recently received much attention in terms of safety. There are several recent case reports in the scientific literature of injuries due to electronic cigarette explosions that involved soft-tissue injuries. CASE REPORT: We report a significant spinal fracture from an electronic-cigarette explosion in a 27-year-old male. The electronic cigarette exploded during use, sending the mouthpiece through the pharynx and into the first cervical vertebra and resulting in fractures of the first and second vertebrae. An x-ray study of the neck showed a foreign body in the neck at the level of C1. A computed tomography scan of the neck showed fractures of C1. The foreign body was removed in the operating room. The patient was discharged home without neurologic sequelae. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Our case report is the first case of a cervical spine injury due to the explosion of an electronic cigarette. This case demonstrates that an electronic cigarette explosion can cause potentially serious penetrating neck injury. Emergency physicians should be aware of the potential danger of electronic cigarettes and have a low threshold to obtain radiographic tests and surgical consultation in the case of electronic cigarette explosion in the oral cavity. As the use of electronic cigarettes continue to increase, it is likely that injuries associated with them will also increase. PMID- 27712902 TI - Response to Letter to the Editor. PMID- 27712905 TI - Whole-breast US following mammography and breast MRI in newly diagnosed breast cancer patients: can it be more than just a guidance tool for biopsy? AB - AIM: To evaluate the role of ultrasound (US) following magnetic resonance imaging (MRI) and mammography in patients with newly diagnosed breast cancers by assessing the additional cancer detection rate of US. MATERIAL AND METHODS: Two hundred and twenty-five women who had undergone 225 MRI examinations followed by US were included. An US-detected additional cancer was defined as a lesion detected using breast US that had not been detected by MRI, and which was shown to be malignant at histopathology. The rate of additional cancer detection, incidence of additional malignancies, positive predictive value (PPV), and false positive (FP) rate were analysed. Factors associated with an increase in the additional cancer detection rate were analysed. RESULTS: The additional cancer detection rate was 0% (0/225) for the ipsilateral breast and 0.9% (2/225) for the contralateral breast, and the PPVs were 0% (0/5) and 100% (2/2), respectively. The overall TP:FP ratio was 0.4 (2:5). The additional cancer detection rate was higher for cases with moderate and severe background parenchymal enhancement than cases with minimal and mild background parenchymal enhancement (p=0.003). The additional cancer detection rate for cases with moderate and severe background parenchymal enhancement was 5.7% (2/35) for the contralateral breast (p=0.003). CONCLUSION: Preoperative breast US following MRI and mammography can help clinicians screen for contralateral cancers with an additional detection rate of 0.9%. Moreover, whole-breast US might be a useful contralateral screening modality in cases with moderate or marked parenchymal enhancement on breast MRI. PMID- 27712903 TI - End-tidal CO2 on admission is associated with hemorrhagic shock and predicts the need for massive transfusion as defined by the critical administration threshold: A pilot study. AB - BACKGROUND: Critical administration threshold (>=3 units of packed red blood cells/h or CAT+) has been proposed as a new definition for massive transfusion (MT) that includes volume and rate of blood transfusion. CAT+ has been shown to eliminate survivor bias and be a better predictor of mortality than the traditional MT (>10 units/24h). End-tidal CO2 (ET CO2) negatively correlates with lactate and is an early predictor of shock in trauma patients. We conducted a pilot study to test the hypothesis that low ET CO2 on admission predicts CAT+. METHODS: ET CO2 via capnography and serum lactate were prospectively collected on admission for 131 patients requiring trauma team activation. Demographic data were obtained from patient charts. Excluded were patients with isolated head injuries, traumatic arrests, or pre-hospital intubations. CAT+/- status was determined for each hour up to 6h from admission as described; likewise, MT+/- status was determined up to 24h from admission. RESULTS: After exclusion criteria, 67 patients were analyzed. Mean age was 41.2 (SD 18.5). Thirty-three patients had a blunt mechanism of injury (49%), median ISS was 9 (interquartile range 4-19), and there were 6 deaths (9%). ET CO2 and lactate were negatively correlated by Spearman rank-based correlation (rho=-0.41, p=0.0006). Twenty-one (31%) and 8 (12%) patients were CAT+ and traditional MT+, respectively. There were a significantly greater proportion of patients with ISS>15, ET CO2 <35, or who died found to be CAT+. A binomial logistic regression model adjusting for age, SBP <90, HR, and ISS >15 revealed ET CO2 < 35 to be independently predictive of CAT+ (OR 9.24, 95% CI 1.51-56.57, p=0.016). CONCLUSIONS: This pilot study demonstrated that low ET CO2 had strong association with standard indicators for shock and was predictive of patients meeting CAT+ criteria in the first 6h after admission. Further study to verify these results and to elucidate CAT criteria's association with mortality will require a larger sample size. PMID- 27712904 TI - Factors affecting planned return to work after trauma: A prospective descriptive qualitative and quantitative study. AB - The use of patient reported outcome measures (PROMs) in trauma is limited. The aim of this pilot study is to evaluate qualitative responses and factors affecting planned return to work following significant trauma, for which there is currently a poor evidence base. National ethical approval was obtained for routine prospective PROMs data collection, including EQ-5D, between Sept 2013 and March 2015 for trauma patients admitted to the Sussex Major Trauma Centre (n=92). 84 trauma patients disclosed their intended return to work at discharge. Additional open questions asked 'things done well' and 'things to be improved'. EQ-5D responses were valued using the time trade-off method. Statistical analysis between multiple variables was completed by ANOVA, and with categorical categories by Chi squared analysis. Only 18/68 of patients working at admission anticipated returning to work within 14days post-discharge. The injury severity scores (ISS) of those predicting return to work within two weeks and those predicting return to work longer than two weeks were 14.17 and 13.59, respectively. Increased physicality of work showed a trend towards poorer return to work outcomes, although non-significant in Chi-squared test in groups predicting return in less than or greater than two weeks (4.621, p=0.2017ns). No significant difference was demonstrated in the comparative incomes of patients with different estimated return to work outcomes (ANOVA r2=0.001, P=0.9590ns). EQ 5D scores were higher in those predicting return to work within two weeks when compared to greater than two weeks. Qualitative thematic content analysis of open responses was possible for 66/92 of respondents. Prominent positive themes were: care, staff, professionalism, and communication. Prominent negative themes were: food, ward response time, and communication. This pilot study highlights the importance of qualitative PROMs analysis in leading patient-driven improvements in trauma care. We provide standard deviations for ISS scores and EQ-5D scores in our general trauma cohort, for use in sample size calculations for further studies analysing factors affecting return to work after trauma. PMID- 27712906 TI - Distribution of intravoxel incoherent motion MRI-related parameters in the brain: evidence of interhemispheric asymmetry. AB - AIM: To compare intravoxel incoherent motion (IVIM) magnetic resonance imaging (MRI)-derived true diffusion (D) and perfusion fraction (f)-values of the two hemispheres to detect the presence of asymmetrical differences. MATERIALS AND METHODS: Forty-seven healthy right-handed volunteers were assessed using IVIM imaging. The interhemispheric D- and f-values were compared using paired t-tests and two related-samples Wilcoxon's test. RESULTS: Comparison of the interhemispheric D- and f-values of the grey matter revealed a significant difference in the D-value of the frontal lobe and the f-value of the temporal lobe (p=0.028, p=0.030, respectively). A significant difference in the D-values of the frontal, temporal, and occipital lobes (p=0.003, p=0.005, and p=0.001, respectively) was seen, whereas no significant difference in f-values was seen. CONCLUSIONS: The distribution of the IVIM-derived D- and f-values in the two hemispheres was not completely symmetrical. Radiologists should consider this difference when the contralateral region is used as internal reference to normalise the IVIM imaging results. Average values of the interhemispheric white matter within the same lobe as the lesion may be the best internal reference. PMID- 27712907 TI - Classic signs in head and neck imaging. AB - Radiologists have long relied upon the use of metaphoric imaging signs to attribute meaning to disease or anatomy-specific imaging patterns encountered in clinical imaging. Teachers of radiology often employ the use of such signs to help learners rapidly identify the typical appearance of various pathologies. Head and neck (H&N) imaging is no exception, and as a specialty that deals with uncommon pathologies and complex anatomy, learners and practising radiologists alike may benefit from this simplistic, pattern-based approach. In this review, we present a compendium of classic imaging signs of H&N lesions, including signs related to traumatic, infectious, neoplastic, congenital, and inflammatory aetiologies found throughout the spectrum of H&N sites (temporal bones, orbits, paranasal sinuses, larynx, salivary glands, and neck soft tissues). Additionally, we identify potential pitfalls and detail critical clinical ramifications related to the rapid and accurate diagnosis of these pathologies.

PMID- 27712908 TI - How to improve the diagnosis of eosinophilic esophagitis: Experience from a case series in Mexico. AB - INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic, immune disorder mediated largely by food antigens. It shares nonspecific symptoms with gastroesophageal reflux disease (GERD). EoE is rarely reported in Mexico, perhaps due to the racial characteristics of the population or because of insufficient diagnostic suspicion. AIMS: Our aim was to describe a Mexican cohort with EoE and evaluate the usefulness of the clinical history and endoscopy in the EoE diagnosis, in comparison with GERD patients. MATERIALS AND METHODS: A retrospective study was carried out on the clinical characteristics and endoscopic and histopathologic findings in patients with EoE, along with a case control study on patients with GERD. The endoscopic images obtained were interpreted in a blind and randomized manner by 4 gastroenterologists, before and after providing them with information on the characteristic alterations of EoE. The esophageal biopsies were also blinded to 2 pathologists that evaluated their diagnostic correlation. The Fisher's exact test and Mann-Whitney U test were used in the statistical analysis. RESULTS: Fourteen patients with EoE were included in the study. Ten (71%) of them were men and the mean age of the patients was 35 years. There were more subjects with a personal history of asthma (p=0.0023) and food impaction (p=0.04) in the EoE group. The initial evaluation of the endoscopic findings showed 53% correct EoE interpretations and rose to 96% in the second revision (sensitivity 100%, specificity 71%, PPV 65%, NPV 100%). CONCLUSIONS: Mexican patients with EoE have similar characteristics to those of patients in western case series. Clinical awareness of the disorder increases endoscopic diagnosis in up to 40% of cases. PMID- 27712910 TI - Health-Related Quality of Life after Coronary Revascularization: A systematic review with meta-analysis. AB - OBJECTIVE: To conduct a systematic review and meta-analysis to summarize evidence and determine the impact of coronary revascularization (CR) on cardiac patients' Health-Related Quality of Life (HRQoL), highlighting factors that may affect this outcome in patients. METHODS: A systematic search of Medline (Pubmed), EMBASE, Cochrane Library, Sciverse (Science Direct and Scopus) and PsycInfo was conducted to identify studies published from January 2000 to December 2012. Data were analyzed using MIX 2.0 Pro and SPSS 20. RESULTS: Thirty-four longitudinal studies met the inclusion criteria; these studies included 15,992 patients, of whom 8,027 had undergone PCI, 6,348 had undergone CABG and 1,617 had received medication treatment. Moderate long-term effect sizes were revealed for both CR procedures. Both percutaneous coronary interventions (PCI) and coronary artery bypass graft surgery (CABG) had significantly greater effects on HRQoL than did medication; however, the CR procedures did not differ significantly from each other. Moderators included the type of instrument used to assess HRQoL and the study quality. Benefits related to physical functioning were greater than those related to psychosocial functioning in patients treated with CABG. CONCLUSIONS: Empirical research highlights the positive effect of CR on patient HRQoL. Researchers should carefully select the instrument they use to measure HRQoL, as this may affect the results and thus conclusions. More RCTs and between-group studies employing pre-post designs should be conducted before clear conclusions can be drawn. PMID- 27712911 TI - Ulnar artery: The Ulysses ultimate resort for coronary procedures. AB - Despite the increasing worldwide adoption of the transradial access site, the ulnar artery (UA) only very infrequently serves as a primary option for coronary procedures. In contrast to the uncertainty surrounding previous reports regarding the feasibility and safety, recent data from larger registries and randomized trials provide more conclusive evidence that the transulnar route may be safely selected as an alternative arterial access approach. However, a default transulnar strategy appears time-consuming and is associated with higher crossover rates compared with the radial artery (RA). Once arterial access is obtained, the likelihood of a successful coronary procedure is high and similar between the two forearm arteries. The UA has similar flow-mediating vasodilating properties with and seems at least as vulnerable as the RA with regard to incident occlusion, with UA occlusion (UAO) rates being probably higher than previously anticipated. A learning curve effect may not be apparent for crossover rates among experienced radialists, but increasing experience is associated with reduction in the fluoroscopy time, contrast volume and frequency of large hematoma formation. The UA may represents an important alternative access site for coronary procedures, and experienced radial operators should obtain additional skills to perform the transulnar approach. Nevertheless, in view of this method's lower feasibility compared to the RA, an initial ulnar access strategy should be reserved for carefully selected patients to ensure satisfactory cannulation rates.

AB - INTRODUCTION: Local anesthesia using urethral gel has been proven to reduce discomfort of male patients during flexible cystoscopy. This study was a non inferiority study between two lidocain-containing urethral gel (Instillagel(r) Lido and Xylocaine(r) gel). METHODS: A prospective single center study was conducted between June 2014 and November 2014. Male patients seen in the office and in whom a flexible cystoscopy was planned were included in the present study and received urethral instillation of either Xylocaine(r) gel or Instillagel(r) Lido at least 5minutes before flexible cystoscopy. No other anesthetic agent was used. Primary endpoint was pain during the procedure, assessed through visual analog scale (VAS) from 0 to 10. RESULTS: Four hundred and sixty-one men were included: 233 in the Instillagel(r) Lido group and 228 in the Xylocaine(r) gel group. Indications of flexible cystoscopy non-muscle invasive bladder cancer follow-up in 44 % of cases, hematuria work-up in 21 % of cases and lower urinary tract symptoms work-up in 35 %. Patients' age was comparable betwwen both groups: 64.5 years (+/-1.1) in the Instillagel(r) Lido group and 66.2 years (+/-1.1) in the Xylocaine(r) gel group (P=0.29). The mean VAS was 0.8 (+/-0.1) in the Instillagel(r) Lido group and 0.6 (+/-0.1) in the Xylocaine(r) gel group (P=0.10). The non-inferiority criterion was reached (P<0.001) as the average difference in VAS between the two groups was 0.2 with a confidence interval not comprising 1 (CI 97.5 %: -0.47; 0.07). CONCLUSION: In this prospective study, Instillagel(r) Lido was not inferior to Xylocaine(r) gel for local analgesia during flexible cystoscopy in male patients. LEVEL OF EVIDENCE: 4.

AB - : Non-muscle-invasive bladder cancer (NMIBC) is characterised by a high risk of recurrence when performing only a transurethral resection of the bladder (TURB). Intravesical instillations are performed postoperatively to decrease the rate of recurrence. The standard agents currently used are Mitomycin-C (MMC) or bacillus Calmette-Guerin (BCG). In order to further enhance the efficacy of the adjuvant treatments and/or diminish their side effects, alternative treatments are studied. Intravesical MMC combined with hyperthermia could be an interesting alternative active treatment for intermediate- and possibly high-risk NMIBC, and has been investigated in the past years. Two methods for achieving hyperthermia are described and presently evaluated: heating the bladder wall by the mean of an intravesical microwave generator (Synergo(r)) and heating the MMC before it is instilled in the bladder (Combat BRS(r)).

AB - Members of the Acidithiobacillus genus are widely found in extreme environments characterized by low pH and high concentrations of toxic substances, thus it is necessary to identify the cellular mechanisms needed to cope with these harsh conditions. Pan-genome analysis of ten bacteria belonging to the genus Acidithiobacillus suggested the existence of core genome, most of which were assigned to the metabolism-associated genes. Additionally, the unique genes of Acidithiobacillus ferrooxidans were much less than those of other species. A large proportion of Acidithiobacillus ferrivorans-specific genes were mapped especially to metabolism-related genes, indicating that diverse metabolic pathways might confer an advantage for adaptation to local environmental conditions. Analyses of functional metabolisms revealed the differences of carbon metabolism, nitrogen metabolism, and sulfur metabolism at the species and/or strain level. The findings also showed that Acidithiobacillus spp. harbored specific adaptive mechanisms for thriving under extreme environments. The genus Acidithiobacillus had the genetic potential to resist and metabolize toxic substances such as heavy metals and organic solvents. Comparison across species and/or strains of Acidithiobacillus populations provided a deeper appreciation of metabolic differences and environmental adaptation, as well as highlighting the importance of cellular mechanisms that maintain the basal physiological functions under complex acidic environmental conditions. PMID- 27712917 TI - Postoperative (Chemo)Radiotherapy for Oral Cavity Squamous Cell Carcinomas: Outcomes and Patterns of Failure. AB - AIMS: To determine outcomes after adjuvant radiotherapy for squamous cell carcinoma of the oral cavity and to correlate locoregional recurrence patterns with radiotherapy target volumes. MATERIALS AND METHODS: All patients receiving adjuvant radiotherapy+/-chemotherapy after surgery with curative intent for oral cavity squamous cell carcinoma between 2007 and 2012 were retrospectively analysed. Locoregional recurrences were reconstructed on the planning computed tomography scan by both deformable image co-registration and by visual assessment. Recurrences were categorised as in-field, marginal or out-of-field if >95%, 20-95%, and <20% of the recurrence volume was encompassed by 95% of the prescription isodose, respectively. RESULTS: In total, 106 patients with a median follow-up of 42 months were included. Oral cavity subsites included oral tongue (54%) and floor of mouth (32%). Thirty (28%) patients received concurrent chemotherapy. Fifty-five (52%) patients received bilateral neck radiotherapy. Two year overall, disease-free, local disease-free, regional disease-free and distant metastases-free survival were 72, 83, 92, 89, 94%, respectively. On multivariate analysis, extracapsular nodal spread was the only factor significantly associated with inferior overall survival. Fourteen (13%) patients have experienced locoregional failure. Of the eight local recurrences at the primary tumour site, four, three and one were classified as in-field, marginal and out-of-field, respectively. Of 10 regional recurrences, one, one and eight were in-field, marginal and out-of-field. There were 7/21 (33%) contralateral regional recurrences in patients with pN2a/b disease who did not receive contralateral neck irradiation; there were 0/21 (0%) and 0/9 (0%) contralateral regional recurrences in patients with pN0 or pN1 disease, respectively, who did not receive contralateral neck irradiation. CONCLUSION: Marginal recurrences highlight the need for generous target volume delineation. Based upon rates of contralateral regional recurrences, a comprehensive approach to target volume selection should be advised for tumour subsites with bilateral lymphatic drainage in the presence of pN2a/b disease. PMID- 27712916 TI - Mesorhizobium olivaresii sp. nov. isolated from Lotus corniculatus nodules. AB - In this study four Mesorhizobium strains isolated from Lotus corniculatus nodules in Granada (Spain) were characterized. Their 16S rRNA gene sequences were closely related to those of M. albiziae LMG 23507T and M. chacoense Pr5T showing 99.4 and 99.2% similarity values, respectively. The analysis of concatenated rpoB, recA, atpD and glnII genes showed they formed a cluster with internal similarities higher than 97%. The closest species also were M. albiziae LMG 23507T and M. chacoense Pr5T showing similarity values lower than 92% in rpoB, recA and glnII genes and lower than 96.5% in the atpD gene. These results indicated that the L. corniculatus strains belong to a new species of genus Mesorhizobium which was confirmed by DNA-DNA hybridization and phenotypic characterization. Therefore a new species with the name Mesorhizobium olivaresii sp. nov. is proposed, and the type strain is CPS13T (LMG 29295T=CECT 9099T). PMID- 27712918 TI - Enrichment and characterization of acid-tolerant nitrifying sludge. AB - Nitrification is an acidifying process that requires the addition of external alkalinity because of the alkaliphilic nature of the most ammonia-oxidizing bacteria. In this study, aerobic activated sludge was used as inoculum in an internal loop air-lift reactor, which resulted in successful enrichment of acid tolerant nitrifying (ACIN) sludge at pH 6.0 by sequential addition of tea orchard soil suspension. The results showed that ACIN sludge had a remarkable acid tolerant capability with a volumetric ammonia conversion rate of 1.13 kg N m-3 day-1. ACIN sludge showed a higher maximum specific ammonia conversion rate (0.29 g N g-1 VSS day-1) than neutrophilic nitrifying sludge (0.14 g N g-1 VSS day-1) at pH 6.0 and had good resistance against pH fluctuations, with a maximum specific ammonia conversion rate (0.584 g N g-1 VSS day-1) at pH 7.5. Microbial community analysis indicated that the higher abundance of acid tolerant Nitrosospira and ammonia-oxidizing archaea laid a solid foundation for the remarkable acid-tolerant capability of ACIN sludge.

However, there are environmental concerns with the long term storage and implications of a leak from a carbon capture storage (CCS) site. Traditional monitoring lacks clear protocols and relies heavily on physical methods. Here, we discuss the potential of biotechnology, focusing on microbes with a natural ability to utilize and assimilate CO2 through different metabolic pathways. We propose the use of natural microbial communities for CCS monitoring and CO2 utilization, and, with examples, demonstrate how synthetic biology may maximize CO2 uptake within and above storage sites. An integrated physical and biological approach, combined with metagenomics data and biotechnological advances, will enhance CO2 sequestration and prevent large-scale leakages.

PMID- 27712921 TI - Does physiological response to disease incur cost to reproductive ecology in a sexually dichromatic amphibian species? AB - It is well known that the disease chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis (Bd) has contributed to amphibian declines worldwide. The impact of Bd varies, with some species being more susceptible to infection than others. Recent evidence has shown that Bd can have sub-lethal effects, whereby increases in stress hormones have been associated with infection. Could this increased stress response, which is a physiological adaptation that provides an increased resilience against Bd infection, potentially be a trade-off with important life-history traits such as reproduction? We studied this question in adult male frogs of a non-declining species (Litoria wilcoxii). Frogs were sampled for (1) seasonal hormone (testosterone and corticosterone), color and disease profiles, (2) the relationship between disease infection status and hormone levels or dorsal color, (3) subclinical effects of Bd by investigating disease load and hormone level, and (4) reproductive and stress hormone relationships independent of disease. Testosterone levels and color score varied seasonally (throughout the spring/summer months) while corticosterone levels remained stable. Frogs with high Bd prevalence had significantly higher corticosterone levels and lower testosterone levels compared to uninfected frogs, and no differences in color were observed. There was a significant positive correlation between disease load and corticosterone levels, and a significant negative relationship between disease load and testosterone. Our field data provides novel evidence that increased physiological stress response associated with Bd infection in wild frogs, could suppress reproduction by down-regulating gonadal hormones in amphibians, however the impacts on reproductive output is yet to be established. PMID- 27712924 TI - Testosterone administration does not affect men's rejections of low ultimatum game offers or aggressive mood. AB - Correlative evidence suggests that testosterone promotes dominance and aggression. However, causal evidence is scarce and offers mixed results. To investigate this relationship, we administered testosterone for 48h to 41 healthy young adult men in a within-subjects, double-blind placebo-controlled balanced crossover design. Subjects played the role of responders in an ultimatum game, where rejecting a low offer is costly, but serves to destroy the proposer's profit. Such action can hence be interpreted as non-physical aggression in response to social provocation. In addition, subjects completed a self-assessed mood questionnaire. As expected, self-reported aggressiveness was a key predictor of ultimatum game rejections. However, while testosterone affected subjective ratings of feeling energetic and interested, our evidence strongly suggests that testosterone had no effect on ultimatum game rejections or on aggressive mood. Our findings illustrate the importance of using causal interventions to assess correlative evidence.

AB - In open surgical procedures, image-ablate ultrasound arrays performed thermal ablation and imaging on rabbit liver lobes with implanted VX2 tumor. Treatments included unfocused (bulk ultrasound ablation, N = 10) and focused (high-intensity focused ultrasound ablation, N = 13) exposure conditions. Echo decorrelation and integrated backscatter images were formed from pulse-echo data recorded during rest periods after each therapy pulse. Echo decorrelation images were corrected for artifacts using decorrelation measured prior to ablation. Ablation prediction performance was assessed using receiver operating characteristic curves. Results revealed significantly increased echo decorrelation and integrated backscatter in both ablated liver and ablated tumor relative to unablated tissue, with larger differences observed in liver than in tumor. For receiver operating characteristic curves computed from all ablation exposures, both echo decorrelation and integrated backscatter predicted liver and tumor ablation with statistically significant success, and echo decorrelation was significantly better as a predictor of liver ablation. These results indicate echo decorrelation imaging is a successful predictor of local thermal ablation in both normal liver and tumor tissue, with potential for real-time therapy monitoring. PMID- 27712925 TI - Serotonin 1A agonism decreases affiliative behavior in pair-bonded titi monkeys. AB - Relatively little is known about serotonergic involvement in pair-bonding despite its putative role in regulating social behavior. Here we sought to determine if pharmacological elevation of serotonin 1A (5-HT1A) receptor activity would lead to changes in social behavior in pair-bonded male titi monkeys (Callicebus cupreus). Adult males in established heterosexual pairs were injected daily with the selective 5-HT1A agonist 8-OH-DPAT or saline for 15days using a within subjects design. Social behavior with the female pair-mate was quantified, and plasma concentrations of oxytocin, vasopressin, and cortisol were measured. When treated with saline, subjects showed reduced plasma oxytocin concentrations, while 8-OH-DPAT treatment buffered this decrease. Treatment with 8-OH-DPAT also led to decreased plasma cortisol 15minutes post-injection and decreased social behavior directed toward the pair-mate including approaching, initiating contact, lipsmacking, and grooming. The reduction in affiliative behavior seen with increased activity at 5-HT1A receptors indicates a substantial role of serotonin activity in the expression of social behavior. In addition, results indicate that the effects of 5-HT1A agonism on social behavior in adulthood differ between rodents and primates.

AB - beta-Haemolytic streptococci of groups C (GCS) and G (GGS) from human infections typically belong to Streptococcus dysgalactiae and are important human pathogens. Among GGS (183 isolates), several emm-types were identified without significant differences between different sites of isolation. For GCS (79 isolates), the type distribution was markedly different and more restricted.

PMID- 27712928 TI - Colistin enhances therapeutic efficacy of daptomycin or teicoplanin in a murine model of multiresistant Acinetobacter baumannii sepsis. AB - We investigated the efficacy of colistin combined with teicoplanin or daptomycin in an experimental mouse model of multiresistant Acinetobacter baumannii infection. Animal received intraperitoneally 1ml saline containing 2*1010CFU of A. baumannii. Colistin, daptomycin, teicoplanin, and colistin plus daptomycin or teicoplanin were given by intraperitoneal administration 2h after bacterial challenge. A control group received sodium chloride solution. In the in vitro study A. baumannii showed to be susceptible only to colistin with MIC of 2mg/l. In the in vivo study, colistin alone showed a good antimicrobial efficacy. When combined with teicoplanin or daptomycin, colistin produced the lowest bacterial and the best survival rates. In immunological studies, when colistin was associated to daptomycin or teicoplanin, both the number and the cytotoxic activity of NK cells increased. In conclusion, colistin combined with teicoplanin or daptomycin may improve the therapy of multiresistant A. baumannii infection.

PMID- 27712930 TI - Type 4 cardiorenal syndrome. AB - The Acute Dialysis Quality Initiative consensus conference proposed a classification of cardiorenal syndrome (CRS), aiming for a better delineation of each subtype. Although the exact pathophysiology of type 4 CRS is not completely understood, the mechanisms involved are probably multifactorial. There is growing evidence that oxidative stress is a major connector in the development and progression of type 4 CRS. Giving its complexity, poor prognosis and increasing incidence, type 4 CRS is becoming a significant public health problem. Patients with chronic kidney disease are particularly predisposed to cardiac dysfunction, due to the high prevalence of traditional cardiovascular risk factors in this population, but the contribution of risk factors specific to chronic kidney disease should also be taken into account. Much remains to be elucidated about type 4 CRS: despite progress over the last decade, there are still significant questions regarding its pathophysiology and there is as yet no specific therapy. A better understanding of the mechanisms involved may provide potential targets for intervention. The present review will provide a brief description of the definition, epidemiology, diagnosis, prognosis, biomarkers and management strategies of type 4 CRS, and the pathophysiological mechanisms and risk factors presumably involved in its development will be particularly highlighted.

PMID- 27712932 TI - Comparison of cardiovascular responses after injection of lidocaine with either clonidine or adrenaline: a two-year comparative analysis. AB - Our aim was to evaluate the efficacy of clonidine with lidocaine as a local anaesthetic agent for inferior alveolar mandibular nerve blocks for dental extraction. We studied 200 patients who required extraction of mandibular teeth and divided them into two groups of 100 each, the first of which was given lidocaine and adrenaline (12.5MUg/ml) and the second lidocaine and clonidine (15MUg/ml). Cardiovascular vascular variables (blood pressure, heart rate, and mean arterial pressure) were assessed before, during, and after extraction, and postoperative pain was measured on a visual analogue scale. There was a significant reduction in systolic blood pressure (p=0.0001) and heart rate (p=0.000) after injection of clonidine. However, they both increased after injections of lidocaine plus adrenaline, and there was a significant reduction in pain at four hours postoperatively with clonidine (p=0.000). Our results showed that anaesthesia with lidocaine and clonidine decreases systolic blood pressure and heart rate 10minutes after injection for extraction of lower mandibular teeth. We suggest that patients who have local anaesthetic with lidocaine and clonidine are at minimal cardiovascular risk and there is no difference in the onset of anaesthesia.

PMID- 27712934 TI - Effects of TiO2 nanoparticles and sunscreens on coastal marine microalgae: Ultraviolet radiation is key variable for toxicity assessment. AB - Given the large numbers of sunbathers on beaches, sunscreen compounds are being released into the coastal aquatic environment in significant amounts. Until now the effect of these potential pollutants on microbiota has been not well-known. Phytoplankton is a key component of the microbiota community. It forms the basis of the aquatic trophic networks, and any change in the natural population of phytoplankton can affect the structure of aquatic biota. This paper describes an experiment performed outdoors (in natural sunlight conditions including ultraviolet radiation (UVR) and with UVR blocked) on mixed microalgae populations (four species from different key marine taxonomic groups, Nannochloropsis gaditana, Chaetoceros gracilis, Pleurochrysis roscoffensis and Amphidinium carterae), for three days, exposed to a range of concentrations of three commercial sunscreens (with variable TiO2 concentrations: highest concentration for sunscreen C, followed by sunscreen A; and sunscreen B did not contain TiO2 in its composition). With regard to UVR effect, in the absence of sunscreens, the most sensitive species is the centric diatom, Chaetoceros gracilis, and the least is Nannochloropsis gaditana; this last species presented the same behavior in the absence of UVR and with high sunscreen concentrations. The toxicity gradient obtained for sunscreens and nanoparticles under UVR is: TiO2 NPs>Sunscreen C>Sunscreen A>Sunscreen B. The differential sensitivity of microalgae to sunscreens and TiO2 NPs can produce a change in the dynamics of phytoplankton populations and provoke undesirable ecological effects (such as giving dinoflagellates more prominence). The effects of UVR, commonly neglected in bioassays, could alter the results in important ways and should be considered when performing environmentally-relevant bioassays. The toxicity mediated by hydrogen peroxide production associated with the concentration of TiO2 NPs cannot be considered the only factor responsible for the toxicity: the organic compounds in the sunscreens must also be taken into account. PMID- 27712935 TI - Associations of night-time road traffic noise with carotid intima-media thickness and blood pressure: The Whitehall II and SABRE study cohorts. AB - BACKGROUND: Road traffic noise has been linked to increased risk of stroke, for which hypertension and carotid intima-media thickness (cIMT) are risk factors. A link between traffic noise and hypertension has been established, but there are few studies on blood pressure and no studies on cIMT. OBJECTIVES: To examine cross-sectional associations for long-term exposure to night-time noise with cIMT, systolic blood pressure (SBP), diastolic blood pressure (DBP) and hypertension. METHODS: The study population consisted of 2592 adults from the Whitehall II and SABRE cohort studies living within Greater London who had cIMT, SBP and DBP measured. Exposure to night-time road traffic noise (A-weighted dB, referred to as dBA) was estimated at each participant's residential postcode centroid. RESULTS: Mean night-time road noise levels were 52dBA (SD=4). In the pooled analysis adjusted for cohort, sex, age, ethnicity, marital status, smoking, area-level deprivation and NOx there was a 9.1MUm (95% CI: -7.1, 25.2) increase in cIMT in association with 10dBA increase in night-time noise. Analyses by noise categories of 55-60dBA (16.2MUm, 95% CI: -8.7, 41.2), and >60dBA (21.2MUm, 95% CI: -2.5, 44.9) vs. <55dBA were also positive but non-significant, expect among those not using antihypertensive medication and exposed to >60dBA vs. <55dBA (32.6MUm, 95% CI: 6.2, 59.0). Associations for SBP, DPB and hypertension were close to null. CONCLUSIONS: After adjustments, including for air pollution, the association between night-time road traffic noise and cIMT was only observed among non-medication users but associations with blood pressure and hypertension were largely null. PMID- 27712936 TI - GSK621 activates AMPK signaling to inhibit LPS-induced TNFalpha production. AB - LPS stimulation in macrophages/monocytes induces TNFalpha production. We here tested the potential effect of GSK621, a novel AMP-activated protein kinase (AMPK) activator, against the process. In RAW264.7 macrophages, murine bone marrow-derived macrophages (BMDMs), and chronic obstructive pulmonary disease (COPD) patients' monocytes, GSK621 significantly inhibited LPS-induced TNFalpha protein secretion and mRNA synthesis. Inhibition of AMPK, through AMPKalpha shRNA knockdown or dominant negative mutation (T172A), almost abolished GSK621's suppression on TNFalpha in RAW264.7 cells. Reversely, forced-expression of a constitutively-active AMPKalpha (T172D) mimicked GSK621 actions and reduced LPS induced TNFalpha production. Molecularly, GSK621 suppressed LPS-induced reactive oxygen species (ROS) production and nuclear factor kappa B (NFkappaB) activation. In vivo, GSK621 oral administration inhibited LPS-induced TNFalpha production and endotoxin shock in mice. In summary, GSK621 activates AMPK signaling to inhibit LPS-induced TNFalpha production in macrophages/monocytes. PMID- 27712937 TI - Will Medicare Readmission Penalties Motivate Hospitals to Reduce Arthroplasty Readmissions? AB - BACKGROUND: The Centers for Medicare & Medicaid Services (CMS) recently imposed penalties against hospitals with above-average 30-day readmission rates following total joint arthroplasty (TJA). Hospitals must decide whether investments in readmission prevention are worthwhile. This study examines the financial incentives associated with unplanned readmissions before and after invocation of these penalties. METHODS: Financial data were reviewed for 2028 consecutive primary TJAs performed on Medicare beneficiaries over a 2-year period at an urban academic health system. Readmission penalties were estimated in accordance with CMS policies. RESULTS: Unplanned readmissions generated a $4416 median contribution margin. The initial hospitalizations (when the TJA was performed) were financially unfavorable for patients subsequently readmitted relative to those not readmitted due to increased costs of care (P = .002), but these costs were more than outweighed by the increased reimbursement earned during the readmission (P < .001), ultimately making readmitted patients financially preferable (P < .001). Going forward, penalties will be levied for risk-adjusted readmission rates above the national rate of 4.8%. For the institution under review, the penalty per readmission outweighs the financial gains earned through readmission by $12,184, resulting in a net loss from readmissions if the rate exceeds 6.5%. It will be financially optimal to maintain a readmission rate (after risk adjustment) equal to the national average but exceeding that rate will be $7768 more expensive per readmission than undershooting that target. CONCLUSION: If our results are generalizable, unplanned Medicare readmissions have traditionally been financially beneficial, but CMS penalties outweigh this benefit. Thus, penalties should incentivize institutions to maintain below average arthroplasty readmissions rates. PMID- 27712938 TI - Synthesis and anti-inflammatory activity of paeonol analogues in the murine model of complete Freund's adjuvant induced arthritis. AB - A new series of paeonol alkyl ether analogues were synthesized and confirmed with IR, 1H NMR, 13C NMR and HRMS spectra. They have shown anti-inflammatory activities by scavenging mediator of free radicals and inhibiting lipid mediator of inflammation on complete Freund's adjuvant (CFA) induced arthritis in mice. The in vitro and in vivo scavenging ability of free radicals was determined by using chemical analysis and commercial assay kits, respectively. The in vivo inhibiting lipid mediator of inflammation was examined by ELISA. Our results indicated that the substitution of the hydrogen in hydroxyl group at C2 position of paeonol 1 by short carbon chain, in the presence or absence of bromo atom at C5 position, decreased its scavenging ability on radicals (3a or 4a vs 1), while the long alkyl substitution (Cn>14) increased the activity. Compared with 3a or 4a, scavenging abilities of 3a-h or 4a-h gradually increased following the length elongation of alkyl carbon chain. Compounds 3h and 4h showed great scavenging ability on OH, O2-, DPPH, ATBS+ and MDA, and good promotion on T-AOC and SOD. The results of the in vivo inhibiting lipid mediator of inflammation also demonstrated that 3h, 4h exhibited substantial inhibition on enzyme activity of COX-2, PGE2. Therefore, 3h and 4h have great potential to be the novel anti inflammatory drug candidates for the therapy of arthritis. PMID- 27712939 TI - Design, synthesis, and activity evaluation of selective inhibitors of anti apoptotic Bcl-2 proteins: The effects on the selectivity of the P1 pockets in the active sites. AB - The anti-apoptotic Bcl-2 proteins are attractive targets for anti-cancer drug development, and the discovery of their selective inhibitors has become a research focus. In this Letter, obvious differences in the P1 pocket of the active site between Bcl-2, Bcl-xL, and Mcl-1 proteins were proposed by the structural comparison of these proteins. As a result, the groups in their inhibitors binding to the P1 pockets may have significant effect on the selectivity for these proteins. Based on this hypothesis, five types of derivatives of the lead compound B-1 were designed, and several highly selective inhibitors of Bcl-xL (E-1) or Mcl-1 proteins (G) were found. The selective inhibitors of Mcl-1 protein found in this Letter provide new structural types for the development of novel antitumor agents. PMID- 27712940 TI - Host use and seasonality of Culex (Melanoconion) iolambdis (Diptera: Culicidae) from eastern Florida, USA. AB - Culex (Melanoconion) iolambdis (Dyar, 1918) is a mosquito (Diptera: Culicidae) species found throughout much of tropical America, including southern Florida. Relatively few reports are available regarding the ecology of Cx. iolambdis, despite its widespread distribution and putative involvement in transmission of Venezuelan equine encephalitis virus. To quantify habitat and host utilization, adults of Cx. iolambdis were sampled from resting shelters at a field site in Vero Beach, Florida, over a 12-month period. Culex iolambdis (1109 males, 3072 females) constituted more than half (56.76%) of all mosquitoes sampled (24 species) and was active year-round. Unfed females and gravid females of Cx. iolambdis were significantly more abundant in mangrove habitat, while males and blood-fed females were not. PCR-based bloodmeal analysis of 305 females revealed that Cx. iolambdis has very wide host breadth, feeding on birds (37.0% overall), reptiles (26.6%), amphibians (23.3%) and mammals (13.1%). Green heron (Butorides virescens), Southern leopard frog (Lithobates sphenocephala) and American alligator (Alligator mississippiensis) were the most commonly fed upon hosts. Bloodmeals from different host classes varied significantly with season, suggesting that Cx. iolambdis may play a role in the amplification and epidemic transmission of zoonotic arboviruses affecting human health. PMID- 27712941 TI - Effect of energy grass on methane production and heavy metal fractionation during anaerobic digestion of sewage sludge. AB - Anaerobic digestion (AD) is one of the most widely used processes to stabilize waste sewage sludge and produce biogas as renewable energy. The relatively low organic matter content and high heavy metal concentrations in sewage sludge have severely restricted the application and development of AD technology in China. In this study, the effect of energy grass (Pennisetum alopecuroides) addition on methane production and heavy metal fractionation during the AD of sewage sludge was evaluated. Methane production was enhanced by 11.2% by the addition of P. alopecuroides. The addition of P. alopecuroides significantly reduced the percentages of the water-soluble and exchangeable fractions of the target heavy metals in the sewage sludge after AD, and the dominant species were concentrated in Fe-Mn oxide-bound and organic- and sulfide-bound fractions of the digested sludge. The addition of P. alopecuroides at a dosage of 0.3kg significantly (P<0.05) decreased the mobility factors (MFs) of the target heavy metals after AD. In particular, the MFs of Cr and Ni were 61% and 32% lower, respectively, relative to the control. The increase in the added dose did not necessarily lead to further decreases in the MFs of the heavy metals. These results demonstrate that an appropriate addition of energy grass could enhance AD, decrease the mobility of heavy metals and promote heavy metal stabilization in sewage sludge during AD, which is beneficial for the subsequent land application of sewage sludge. PMID- 27712942 TI - Cost and efficiency of disaster waste disposal: A case study of the Great East Japan Earthquake. AB - This paper analyzes the cost and efficiency of waste disposal associated with the Great East Japan Earthquake. The following two analyses were performed: (1) a popular parametric approach, which is an ordinary least squares (OLS) method to estimate the factors that affect the disposal costs; (2) a non-parametric approach, which is a two-stage data envelopment analysis (DEA) to analyze the efficiency of each municipality and clarify the best performance of the disaster waste management. Our results indicate that a higher recycling rate of disaster waste and a larger amount of tsunami sediments decrease the average disposal costs. Our results also indicate that area-wide management increases the average cost. In addition, the efficiency scores were observed to vary widely by municipality, and more temporary incinerators and secondary waste stocks improve the efficiency scores. However, it is likely that the radioactive contamination from the Fukushima Daiichi nuclear power station influenced the results. PMID- 27712943 TI - Liberation of Printed Circuit Assembly (PCA) and dust generation in relation to mobile phone design in a size reduction process. AB - Complex electronic devices entering our recycling systems often generate losses in the whole treatment chain. For better liberation, crucial for the mechanical separation process, the devices are crushed which also generates dusts that are not recovered. This study investigated the relation between the liberation of Printed Circuit Assembly (PCA) and dust generation in the crushing process of two different types of mobile phone samples. The results revealed that the overall PCA grade in both samples was approximately 70% with around 3.4% dust generation. However, the liberation distribution of PCAs differed between mobile phones resulting in better distribution for sophisticated mobile phones due among other things to the initial size of the phones. Further, the dust fractions comprised both noble and valuable metals but also contaminants that need to be taken into account when further processing is planned. A higher gold concentrate was detected in dusts from regular phones since the protective plastic casing crushed more easily thus exposing the PCA surface for grinding. PMID- 27712944 TI - Degradation of organic pollutants by Ag, Cu and Sn doped waste non-metallic printed circuit boards. AB - The disposal and reuse of waste printed circuit boards have been the major global concerns. Printed circuit boards, a form of Electronic waste (hereafter e-waste), have been chemically processed, doped with Ag+, Cu2+ and Sn2+, and used as visible light photocatalysts against the degradation of methylene blue and methyl violet. The elemental analyses of pristine and metal doped printed circuit board were obtained using energy dispersive X-ray fluorescence (EDXRF) spectra and inductively coupled plasma optical emission spectroscopy (ICP-OES). The morphology of parent and doped printed circuit board was obtained from scanning electron microscopy (SEM) measurements. The photocatalytic activity of parent and metal doped samples was carried out for the decomposition of organic pollutants, methylene blue and methyl violet, under visible light irradiation. Metal doped waste printed circuit boards (WPCBs) have shown higher photocatalytic activity against the degradation of methyl violet and methylene blue under visible light irradiation. Scavenger experiments were performed to identify the reactive intermediates responsible for the degradation of methylene blue and methyl violet. The reactive species responsible for the degradation of MV and MB were found to be holes and hydroxyl radicals. A possible mechanism of degradation of methylene blue and methyl violet is given. The stability and reusability of the catalysts are also investigated. PMID- 27712945 TI - A holistic approach to the environmental evaluation of food waste prevention. AB - The environmental evaluation of food waste prevention is considered a challenging task due to the globalised nature of the food supply chain and the limitations of existing evaluation tools. The most significant of these is the rebound effect: the associated environmental burdens of substitutive consumption that arises as a result of economic savings made from food waste prevention. This study introduces a holistic approach to addressing these challenges, with a focus on greenhouse gas (GHG) emissions from household food waste in the UK. It uses a hybrid life cycle assessment model coupled with a highly detailed multi-regional environmentally extended input output analysis to capture environmental impacts across the global food supply chain. The study also takes into consideration the rebound effect, which was modelled using a linear specification of an almost ideal demand system. The study finds that food waste prevention could lead to substantial reductions in GHG emissions in the order of 706-896kg CO2-eq. per tonne of food waste, with most of these savings (78%) occurring as a result of avoided food production overseas. The rebound effect may however reduce such GHG savings by up to 60%. These findings provide a deeper insight into our understanding of the environmental impacts of food waste prevention: the study demonstrates the need to adopt a holistic approach when developing food waste prevention policies in order to mitigate the rebound effect and highlight the importance of increasing efficiency across the global food supply chain, particularly in developing countries.

PMID- 27712948 TI - Community Organizing for Healthier Communities: Environmental and Policy Outcomes of a National Initiative. AB - INTRODUCTION: Childhood obesity is disproportionately prevalent in communities of color, partially because of structural inequities in the social and built environment (e.g., poverty, food insecurity, pollution) that restrict healthy eating and active living. Community organizing is an underexamined, grassroots health promotion approach that empowers and mobilizes community residents to advocate for, and achieve, environmental and policy changes to rectify these structural inequities. This paper presents outcomes of the Robert Wood Johnson Foundation's Communities Creating Healthy Environments initiative: the first national program to apply community organizing to combat childhood obesity causing structural inequities in communities of color. METHODS: Twenty-one community-based organizations and tribal nations (grantees) conducted 3-year community organizing-based interventions primarily designed to increase children's healthy food and safe recreational access. Grantees' policy wins (environmental and policy changes resulting from grantee interventions) were measured from 2009 to 2014 using semi-structured interviews conducted quarterly and 6 months post-grant, and independently coded and reviewed in 2015 by researchers and expert community organizers. RESULTS: The 21 grantees achieved 72 policy wins (mean=3.43, SD=1.78) across six domains: two directly addressed childhood obesity by enhancing children's healthy food (37.50%) and recreational access (33.33%), whereas four indirectly addressed obesity by promoting access to quality health care (8.33%); clean environments (9.73%); affordable housing (8.33%); and discrimination- and crime-free neighborhoods (2.78%). CONCLUSIONS: These findings provide compelling evidence that community organizing-based interventions designed and led by community stakeholders can achieve diverse environmental and policy solutions to the structural inequities that foment childhood obesity in communities of color.

AB - BACKGROUND: Maintaining high treatment adherence levels is critical for effective management of chronic diseases. The Adherence Starts with Knowledge 20 (ASK-20) questionnaire is the only linguistically validated patient-reported treatment adherence tool available in Japan. We conducted additional analyses on ASK-20 data from Japanese adults with asthma. METHODS: This was a prospective, non interventional, single-visit, multi-centre study in Japanese adults (n = 300) with asthma receiving long-term treatment with inhaled corticosteroids (ICS) or ICS/long-acting beta-agonists. We tested the reliability, validity and the relationship between different adherence conditions and ASK-20 score. At one centre, ICS adherence prescription rate was calculated retrospectively based on 2 year percentage ICS adherence data contained within medical records. RESULTS: The ASK-20 had good internal consistency reliability (Cronbach's alpha = 0.76; n = 290). Discriminant validity was demonstrated with significant correlations between the percentage ICS adherence rates and both the mean ASK-20 total score and mean total barrier count (TBC) (r = -0.51 and -0.58, p < 0.001; n = 111). The ASK-20 total score discriminated between subjects with good and poor adherence measured by patients' reported questionnaire and between those of high and low percentage ICS adherence rates. All other factors that possibly affect adherence were correlated with the mean ASK-20 total score and mean TBC in addition to the number of medicines taken every day. CONCLUSIONS: The Japanese ASK-20 is a reliable tool for assessing possible medication adherence barriers and adherence behaviour in Japanese adults with asthma. Furthermore, our results are comparable with those obtained using the ASK-20 in the United States. PMID- 27712950 TI - Health Disparities and the Microbiome.

PMID- 27712951 TI - Meningococcal Biofilm Formation: Let's Stick Together. AB - Extracellular DNA (eDNA) is an essential constituent of the extracellular matrix of biofilms of many microorganisms. In spite of many studies, it has long remained unclear how exactly eDNA exerts its role in biofilm formation. Here, we describe recent advances that have been made in understanding biofilm formation in the human pathogen Neisseria meningitidis. Several cell-surface-exposed proteins have been identified that bind DNA and other negatively charged polymers, such as heparin, by electrostatic interactions. By virtue of these proteins, eDNA can act as an adhesive that binds the bacteria together. We provide examples that indicate that the mechanism of binding eDNA via DNA/heparin binding proteins is a conserved feature in biofilms of many different microorganisms, including fungi.

AB - In this narrative review, we locate within the tradition of great diagnosticians in internal medicine, a fundamental development in patient-centered care: shared decision making (SDM).

PMID- 27712955 TI - Neural stem cells from mouse strain Thy1 YFP-16 are a valuable tool to monitor and evaluate neuronal differentiation and morphology. AB - To analyse events following transplantation of stem cells in the brain robust tools for tracing stem cells are required. Here we took advantage of the mouse strain B6.Cg-Tg(Thy1-YFP)16Jrs/J (Thy1 YFP-16), where yellow fluorescent protein (YFP) is under control of the promoter of Thy1 gene. This allows visualising whole neurons, i.e. their cell body, axons and dendrites. In this work fluorescent cells were followed during embryonic development, in vitro differentiation, and after transplantation in the healthy and stroke-affected mouse brain. During embryonic development Thy1-YFP positive cells were first observed on E12.5 and subsequently located in the prosencephalon, rhombencephalon, spinal cord and peripheral nerves. Quantitative analysis by RT PCR and immunocytochemistry revealed that Thy1-YFP positive cells during embryo development and in vitro differentiation were expressing nestin and SOX2 then MAP2, beta3-tubulin and NeuN. Thy1-YFP positive cells isolated from E14.5 represented 21.88+/-053% (SD) of the cultivated neurons and this remained constant along in vitro differentiation. On the other hand, proportion of Thy1 YFP positive cells reached 50% of neurons in perinatal and one month old mouse brain. Neural stem cells isolated from Thy1 YFP-16 mouse strain transplanted near hippocampus of the healthy and stroke-affected brain were distinguishable by YFP fluorescence. They differentiated into mature neurons and were detectable even 14 weeks after transplantation, the end point of our experiment. In conclusion, stem cells originating from Thy1 YFP-16 mice represent an outstanding tool to monitor neurogenesis enabling morphological analyses of new neurons and their projections, in particular after transplantation in the brain. PMID- 27712952 TI - Chlamydial Plasmid-Dependent Pathogenicity. AB - Most Chlamydia species carry a 7.5kb plasmid encoding eight open reading frames conventionally called plasmid glycoproteins 1-8 or pGP1-8. Although the plasmid is not critical for chlamydial growth in vitro, its role in chlamydial pathogenesis is clearly demonstrated in the genital tracts of mice infected with Chlamydia muridarum, a model for investigating the human pathogen Chlamydia trachomatis. Plasmid-free C. trachomatis is also attenuated in both the mouse genital tract and nonhuman primate ocular tissue. Deficiency in pGP3 alone, which is regulated by pGP4, largely reproduced the in vivo but not in vitro phenotypes of the plasmid-free organisms, suggesting that pGP3 is a key in vivo virulence factor. The positive and negative regulations of some chromosomal genes by pGP4 and pGP5, respectively, may allow the plasmid to promote chlamydial adaptation to varied animal tissue environments. The focus of this review is to summarize the progress on the pathogenic functions of the plasmid-encoded open reading frames, which may motivate further investigation of the molecular mechanisms of chlamydial pathogenicity and development of medical utility of the chlamydial plasmid system.

AB - Since the publication of the 2012 guidelines new literature has emerged to inform decision-making. The 2016 guidelines primary panel selected a number of clinically relevant questions and has produced updated recommendations, on the basis of important new findings. In subjects with clinical atherosclerosis, abdominal aortic aneurysm, most subjects with diabetes or chronic kidney disease, and those with low-density lipoprotein cholesterol >= 5 mmol/L, statin therapy is recommended. For all others, there is an emphasis on risk assessment linked to lipid determination to optimize decision-making. We have recommended nonfasting lipid determination as a suitable alternative to fasting levels. Risk assessment and lipid determination should be considered in individuals older than 40 years of age or in those at increased risk regardless of age. Pharmacotherapy is generally not indicated for those at low Framingham Risk Score (FRS; <10%). A wider range of patients are now eligible for statin therapy in the FRS intermediate risk category (10%-19%) and in those with a high FRS (> 20%). Despite the controversy, we continue to advocate for low-density lipoprotein cholesterol targets for subjects who start therapy. Detailed recommendations are also presented for health behaviour modification that is indicated in all subjects. Finally, recommendation for the use of nonstatin medications is provided. Shared decision-making is vital because there are many areas in which clinical trials do not fully inform practice. The guidelines are meant to be a platform for meaningful conversation between patient and care provider so that individual decisions can be made for risk screening, assessment, and treatment. PMID- 27712956 TI - Alternative Splicing May Not Be the Key to Proteome Complexity. AB - Alternative splicing is commonly believed to be a major source of cellular protein diversity. However, although many thousands of alternatively spliced transcripts are routinely detected in RNA-seq studies, reliable large-scale mass spectrometry-based proteomics analyses identify only a small fraction of annotated alternative isoforms. The clearest finding from proteomics experiments is that most human genes have a single main protein isoform, while those alternative isoforms that are identified tend to be the most biologically plausible: those with the most cross-species conservation and those that do not compromise functional domains. Indeed, most alternative exons do not seem to be under selective pressure, suggesting that a large majority of predicted alternative transcripts may not even be translated into proteins. PMID- 27712957 TI - Increased risk for knee replacement surgery after arthroscopic surgery for degenerative meniscal tears: a multi-center longitudinal observational study using data from the osteoarthritis initiative. AB - OBJECTIVE: The primary objective was to assess whether patients with knee osteoarthritis and whom undergo arthroscopic meniscectomy have an increased risk for future knee replacement surgery. DESIGN: Data used were obtained from the Osteoarthritis Initiative (OAI) study. SETTING: Participants were enrolled, in four clinical centers, between February 2004 and May 2006 and were followed up on an annual basis up to and including 108-months from enrollment. PARTICIPANTS: 4674 participants (58.4% female), aged 45-79, of all ethnic groups, who had, and those who were at high risk for developing, symptomatic knee osteoarthritis were included, of which 3337 (71.4%) were included in the final follow up visit. MAIN OUTCOME MEASURES: Hazard ratio of knee replacement surgery for participants who underwent arthroscopic meniscectomy during follow up compared to propensity score matched participants who did not undergo arthroscopic meniscectomy during follow up. RESULTS: 335 participants underwent arthroscopic meniscectomy during follow up, of which 63 (18.8%) underwent knee replacement surgery in the same knee. Of the 335 propensity score matched participants 38 (11.1%) underwent knee replacement surgery during follow up. Results from the Cox-proportional hazards model demonstrated that the hazard ratio of knee replacement surgery was 3.03 (95% CI (1.67-5.26)) for participants who underwent arthroscopic meniscectomy relative to the propensity score matched participants who did not undergo arthroscopic meniscectomy. CONCLUSIONS: In patients with knee osteoarthritis arthroscopic knee surgery with meniscectomy is associated with a three fold increase in the risk for future knee replacement surgery.

AB - BACKGROUND/PURPOSE: Myofunctional therapy is one of the recommended treatments for obstructive sleep apnea, but the level of compliance has often been low in children. This study aims to investigate the therapeutic effect of passive myofunctional therapy using an oral appliance during sleep in children suffering from obstructive sleep apnea. METHODS: Twenty-nine children who suffered from obstructive sleep apnea were divided into two groups: premature children and full term children. All children wore an oral device to induce their tongue muscle activity during sleep for 6 months. Polysomnography during sleep was performed before and 1 week after the end of 6-month treatment. RESULTS: Both groups showed positive polysomnographic changes. Full-term children had a significant decrease in the apnea-hypopnea index, hypopnea index, and percentage of arousals. Prematurely born children had a significant decrease in the apnea-hypopnea index during rapid eye movement sleep and in the mean heart rate during sleep. CONCLUSION: Using a specialized oral device to perform myofunctional therapy during sleep may improve the breathing during sleep of children with obstructive sleep apnea. PMID- 27712962 TI - Risk factors for candidemia mortality in hospitalized children. AB - OBJECTIVE: To evaluate risk factors associated with death due to bloodstream infection caused by Candida spp. in pediatric patients and evaluate the resistance to the main anti-fungal used in clinical practice. METHODS: This is a cross-sectional, observational, analytical study with retrospective collection that included 65 hospitalized pediatric patients with bloodstream infection by Candida spp. A univariate analysis was performed to estimate the association between the characteristics of the candidemia patients and death. RESULTS: The incidence of candidemia was 0.23 cases per 1000patients/day, with a mortality rate of 32% (n=21). Clinical outcomes such as sepsis and septic shock (p=0.001), comorbidities such as acute renal insufficiency (p=0.01), and risks such as mechanical ventilation (p=0.02) and dialysis (p=0.03) are associated with increased mortality in pediatric patients. The resistance and dose-dependent susceptibility rates against fluconazole were 4.2% and 2.1%, respectively. No resistance to amphotericin B and echinocandin was identified. CONCLUSION: Data from this study suggest that sepsis and septic shock, acute renal insufficiency, and risks like mechanical ventilation and dialysis are associated with increased mortality in pediatric patients. The mortality among patients with candidemia is high, and there is no species difference in mortality rates. Regarding the resistance rates, it is important to emphasize the presence of low resistance in this series. PMID- 27712961 TI - Physical self-efficacy is associated to body mass index in schoolchildren. AB - OBJECTIVE: The present study aimed to investigate the relationship between physical self-efficacy and body mass index in a large sample of schoolchildren. METHODS: The Perceived Physical Ability Scale for Children was administered to 1560 children (50.4% boys; 8-12 years) from three different countries. Weight and height were also recorded to obtain the body mass index. RESULTS: In agreement with the literature, the boys reported greater perceived physical self-efficacy than girls. Moreover, the number of boys who are obese is double that of girls, while the number of boys who are underweight is half that found in girls. In the linear regression model, the increase in body mass index was negatively related to the physical self-efficacy score, differently for boys and girls. Furthermore, age and nationality also were predictors of low physical self-efficacy only for girls. CONCLUSION: The results of this study reinforce the importance of psychological aspect of obesity, as the perceived physical self-efficacy and body mass index were negatively associated in a sample of schoolchildren for boys and girls. PMID- 27712963 TI - Effect of classic ketogenic diet treatment on lipoprotein subfractions in children and adolescents with refractory epilepsy. AB - OBJECTIVE: The aim of this study was to evaluate the effects of the classic ketogenic diet (KD) on low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subfractions in children and adolescents with refractory epilepsy. METHODS: This prospective study recruited children and adolescents of either sex, whose epilepsy was refractory to treatment with multiple drugs. To be included, the patient had to have an indication for treatment with the KD and be treated as an outpatient. At baseline and after 3 and 6 mo of the KD, lipid profile (total cholesterol [TC], triacylglycerols [TG], LDL cholesterol [LDL-C], and HDL cholesterol [HDL-C]), apolipoproteins (apoA-I and apoB), 10 subfractions of HDL, 7 subfractions of LDL, LDL phenotype, and LDL size were analyzed using the Lipoprint system. RESULTS: The lipid profile components (TC, TG, LDL-C, HDL-C, apoA-I, and apoB) increased during the 3-mo follow-up, and remained consistent after 6 mo of treatment. Similarly, non-HDL-C, TC/HDL-C, LDL-C/HDL-C, and apoB/apoA-I ratios, representing atherogenic particles, significantly increased. In contrast, qualitative lipoprotein characteristics progressively changed during the follow-up period. Small LDL subfractions increased, and this profile was related with reduced LDL size (27.3 nm to 26.7 nm). The LDL phenotype became worse; 52.1% of the patients had a non-A phenotype after 6 mo of the KD. Small HDL subfractions decreased only after 6 mo of the KD. CONCLUSIONS: KD treatment promotes negative changes in lipoprotein size and phenotype, contributing to atherogenic risk in these patients. PMID- 27712958 TI - Nutrients and the microenvironment to feed a T cell army. AB - T cells have dramatic functional and proliferative shifts in the course of maintaining immune protection from pathogens and cancer. To support these changes, T cells undergo metabolic reprogramming upon stimulation and again after antigen clearance. Depending on the extrinsic cell signals, T cells can differentiate into functionally distinct subsets that utilize and require diverse metabolic programs. Effector T cells (Teff) enhance glucose and glutamine uptake, whereas regulatory T cells (Treg) do not rely on significant rates of glycolysis. The dependence of these subsets on specific metabolic programs makes T cells reliant on these signaling pathways and nutrients. Metabolic pathways, such as those regulated by mTOR and Myc, augment T cell glycolysis and glutaminolysis programs to promote T cell activity. These pathways respond to signals and control metabolism through both transcriptional or post-transcriptional mechanisms. Epigenetic modifications also play an important role by stabilizing the transcription factors that define subset specific reprogramming. In addition, circadian rhythm cycling may also influence energy use, immune surveillance, and function of T cells. In this review, we focus on the metabolic and nutrient requirements of T cells, and how canonical pathways of growth and metabolism regulate nutrients that are essential for T cell function. PMID- 27712964 TI - Relationship between sodium and potassium intake and blood pressure in a sample of overweight adults. AB - OBJECTIVE: The aim of this study was to examine the relationship between sodium and potassium intakes and blood pressure (BP) in a clinical sample. METHODS: Secondary analysis of baseline data from 328 participants (mean age: 43.6 +/- 8 y, mean body mass index [BMI]: 32.4 +/- 4.2 kg/m2, mean systolic BP [SBP]/diastolic BP [DBP]: 124.9 +/- 14.5/73.3 +/- 9.9 mm Hg) of the 12-mo HealthTrack randomized controlled weight loss trial was conducted. Resting BP and 24-h urine sodium and potassium were measured. Dietary intake was evaluated with 4-d food records and self-reported diet histories. RESULTS: Urinary sodium was positively correlated (Spearman's rho) with SBP (r = 0.176; P = 0.001) and DBP (r = 0.150; P = 0.003). The ratio of sodium to potassium was positively correlated with SBP (r = 0.1; P = 0.035). Urinary sodium (F [4,323] = 20.381; P < 0.0005; adjusted R2 = 0.231) and sodium-to-potassium ratio (F[4,323] = 25.008; P < 0.0005; adjusted R2 = 0.227) significantly predicted SBP after controlling for age, sex, BMI, and hypertension medication use. Dietary sodium and potassium significantly predicted urinary sodium (B = 0.33, t = 4.032, P < 0.01) and potassium (B = 0.67, t = 8.537, P < 0.01) excretion, respectively, after adjustment for energy and BMI. Median dietary sodium intake was 3197 mg/d and median dietary potassium intake was 2886 mg/d. Cereal-based products and dishes were the major contributors (22%) to total sodium intake. CONCLUSIONS: In the present study, a high dietary sodium intake and high sodium-to-potassium ratio predicted high SBP. This suggests a need to focus dietary advice on reduction of sources of sodium and increasing sources of potassium in weight loss interventions to improve BP control. PMID- 27712965 TI - Systemic inflammation, growth factors, and linear growth in the setting of infection and malnutrition. AB - OBJECTIVES: Deficits in weight gain and linear growth are seen frequently among children in areas where malnutrition and recurrent infections are common. Although both inflammation and malnutrition can result in growth hormone (GH) resistance, the interrelationships of infection, inflammation, and growth deficits in developing areas remain unclear. The aim of this study was to evaluate relationships between low levels of systemic inflammation, growth factors, and anthropometry in a case-control cohort of underweight and normal weight children in northern Brazil. METHODS: We evaluated data from 147 children ages 6 to 24 mo evaluated in the MAL-ED (Interactions of Malnutrition and Enteric Disease) case-control study following recruitment from a nutrition clinic for impoverished families in Fortaleza, Brazil. We used nonparametric tests and linear regression to evaluate relationships between current symptoms of infections (assessed by questionnaire), systemic inflammation (assessed by high sensitivity C-reactive protein [hsCRP]), the GH insulin-like growth factor-1 (IGF 1) axis, and measures of anthropometry. All models were adjusted for age and sex. RESULTS: Children with recent symptoms of diarrhea, cough, and fever (compared with those without symptoms) had higher hsCRP levels; those with recent diarrhea and fever also had lower IGF-1 and higher GH levels. Stool myeloperoxidase was positively associated with serum hsCRP. hsCRP was in turn positively associated with GH and negatively associated with IGF-1 and IGF-binding protein-3 (IGFBP-3), suggesting a state of GH resistance. After adjustment for hsCRP, IGF-1 and IGFBP 3 were positively and GH was negatively associated with Z scores for height and weight. CONCLUSIONS: Infection and inflammation were linked to evidence of GH resistance, whereas levels of GH, IGF-1, and IGFBP-3 were associated with growth indices independent of hsCRP. These data implicate complex interrelationships between infection, nutritional status, GH axis, and linear growth in children from a developing area. PMID- 27712966 TI - Impact of glucose tolerance status on the development of coronary artery disease among working-age men. AB - AIMS: To examine the impact of glucose tolerance status on the development of coronary artery disease (CAD) in working-age men in Japan. METHODS: This population-based retrospective cohort study included 111,621 men aged 31-60 years [63,558 with normal glucose tolerance (NGT); 37,126 with prediabetes; 10,937 with diabetes]. The Cox proportional-hazards regression model was used to identify variables related to the incidence of CAD. RESULTS: Multivariate analysis showed that, compared with NGT, diabetes increased the risk of CAD by 17.3 times (95% CI: 6.36-47.0) at ages 31-40 years, by 2.74 times (95% CI: 1.85-4.05) at ages 41 50 years and by 2.47 times (95% CI: 1.69-3.59) at ages 51-60 years. The HRs for CAD in men with diabetes aged 31-40 equaled that of men with NGT aged 51-60 [18.2 (7.15-46.4) and 19.4 (8.28-45.4), respectively]. CONCLUSION: The impact of diabetes on CAD was markedly greater in men aged 31-40 years compared with those aged 41-60 years.

PMID- 27712970 TI - Implementing a Statistical Model for Protamine Titration: Effects on Coagulation in Cardiac Surgical Patients. AB - OBJECTIVES: To implement a statistical model for protamine titration. DESIGN: Prospective randomized trial. SETTING: University hospital. PARTICIPANTS: Sixty (n = 30+30) patients scheduled for elective coronary artery bypass surgery were randomly assigned to 2 groups. INTERVENTIONS: Protamine dose calculated according to an algorithm established from a statistical model or to a fixed protamine heparin dose ratio (1:1). MEASUREMENTS AND MAIN RESULTS: Both groups demonstrated comparable patient demographics and intraoperative data. Coagulation effects were evaluated using rotational thromboelastometry. Using the statistical model reduced (p<0.01) the protamine dose from 426+/-43 mg to 251+/-66 mg, followed by significantly (p<0.01) shorter intrinsic clotting time (208+/-29 seconds versus 244+/-52 seconds) and stronger clot firmness (p = 0.01), and effects on indices of extrinsic or fibrinogen coagulation pathways were insignificant. Test of residual heparin was negative in all patients after protamine administration, aligned with insignificant (p = 0.27) intergroup heparinase-verified clotting time differences. CONCLUSIONS: The statistical model for protamine titration is clinically feasible and protects the patient from exposure to excessive doses of protamine, with advantageous effects on coagulation as measured using rotational thromboelastometry. Significance regarding clinical outcome is yet to be defined.

AB - BACKGROUND: In times of modern surgery, transplantation and percutaneous techniques, pyogenic liver abscess (PLA) has essentially become a problem of biliary or iatrogenic origin. In the current scenario, diagnostic approach, clinical behavior and therapeutic outcomes have not been profoundly studied. This study analyzes the clinical and microbiological features, diagnostic methods, therapeutic management and predictive factors for recurrence and mortality of first episodes of PLA. METHODS: A retrospective single-center study was conducted including 142 patients admitted to the Hospital Italiano de Buenos Aires, between 2005 and 2015 with first episodes of PLA. RESULTS: Prevailing identifiable causes were biliary diseases (47.9%) followed by non-biliary percutaneous procedures (NBIPLA, 15.5%). Seventeen patients (12%) were liver recipients. Eleven patients (7.8%) died and 18 patients (13.7%) had recurrence in the first year of follow up. The isolation of multiresistant organisms (p = 0.041) and a history of cholangitis (p < 0.001) were independent risk factors for recurrence. Mortality was associated with serum bilirubin >5 mg/dL (p = 0.022) and bilateral involvement (p = 0.014) in the multivariate analysis. CONCLUSION: NBPLA and PLA after transplantation may be increasing among the population of PLA in referral centers. History of cholangitis is a strong predictor for recurrence. Mortality is associated to hiperbilirrubinemia and anatomical distribution of the lesions. PMID- 27712974 TI - Utility of cytopathological specimens and an automated image analysis for the evaluation of HER2 status and intratumor heterogeneity in breast carcinoma. AB - OBJECTIVES: Although updated HER2 testing guidelines have been improved by a collaboration between the American Society of Clinical Oncology (ASCO) and the College of American Pathologists (CAP) in 2013, HER2 evaluation is still problematic because of issues involving CEP17 polysomy, heterogeneity, and HER2 score 2+ cases. The aim of this retrospective study was to evaluate the relationship between HER2 gene heterogeneity, or so called CEP17 polysomy, using breast carcinoma cells sampled by scraping and the IHC score graded by automated image analysis using whole slide image. MATERIAL AND METHODS: We randomly selected 23 breast carcinoma cases with a HER2 score 0, 24 cases with a HER2 score 1+, 24 cases with HER2 score 2+, and 23 cases with HER2 score 3+ from the records of patients with breast cancer at Hiroshima University Hospital. We compared the results of fluorescent in situ hybridization (FISH) using formalin fixed, paraffin-embedded (FFPE) tissues and cytological samples and compared the HER2 score calculated using an automated image analysis using wholly scanned slide images and visual counting. RESULTS: We successfully performed the FISH assay in 78 of 94 cases (83%) using FFPE tissues and in all 94 (100%) cases using cytological samples. Frequency of both HER2 amplification and CEP17 polysomy was higher when cytological samples were used than when FFPE tissue was used. Frequency of HER2 heterogeneity using cytological samples was higher that than using FFPE tissue, except for the IHC score 3+ cases. CONCLUSIONS: When assessment of HER2 status based on FISH using FFPE tissue cannot be accomplished, FISH using cytological samples should be considered. When intensity of HER2 is heterogeneous in the tumor tissue, particularly in cases regarded as score 2+, they should be evaluated by automated image analysis using the whole slide image. PMID- 27712973 TI - Ebselen exerts antifungal activity by regulating glutathione (GSH) and reactive oxygen species (ROS) production in fungal cells. AB - BACKGROUND: Ebselen, an organoselenium compound and a clinically safe molecule has been reported to possess potent antifungal activity, but its antifungal mechanism of action and in vivo antifungal activity remain unclear. METHODS: The antifungal effect of ebselen was tested against Candida albicans, C. glabrata, C. tropicalis, C. parapsilosis, Cryptococcus neoformans, and C. gattii clinical isolates. Chemogenomic profiling and biochemical assays were employed to identify the antifungal target of ebselen. Ebselen's antifungal activity in vivo was investigated in a Caenorhabditis elegans animal model. RESULTS: Ebselen exhibits potent antifungal activity against both Candida spp. and Cryptococcus spp., at concentrations ranging from 0.5 to 2MUg/ml. Ebselen rapidly eradicates a high fungal inoculum within 2h of treatment. Investigation of the drug's antifungal mechanism of action indicates that ebselen depletes intracellular glutathione (GSH) levels, leading to increased production of reactive oxygen species (ROS), and thereby disturbs the redox homeostasis in fungal cells. Examination of ebselen's in vivo antifungal activity in two Caenorhabditis elegans models of infection demonstrate that ebselen is superior to conventional antifungal drugs (fluconazole, flucytosine and amphotericin) in reducing Candida and Cryptococcus fungal load. CONCLUSION: Ebselen possesses potent antifungal activity against clinically relevant isolates of both Candida and Cryptococcus by regulating GSH and ROS production. The potent in vivo antifungal activity of ebselen supports further investigation for repurposing it for use as an antifungal agent. GENERAL SIGNIFICANCE: The present study shows that ebselen targets glutathione and also support that glutathione as a potential target for antifungal drug development. PMID- 27712975 TI - Decreased PLK1 expression denotes therapy resistance and unfavourable disease free survival in rectal cancer patients receiving neoadjuvant chemoradiotherapy. AB - AIM: Polo-like kinase 1 (Plk1) plays a key role in mitotic cell division and DNA damage repair. It has been observed that either up-regulated or down-regulated Plk1 could induce mitotic defects that results in aneuploidy and tumorigenesis, probably depending on the context. Few previous reports have associated Plk1 expression with prognosis and response to radiotherapy in rectal carcinomas. The aim of this study is to investigate the prognostic impact of Plk1 expression and its role in predicting response to neoadjuvant cheomoradiotherapy in rectal cancer. METHODS AND RESULTS: Immunohistochemical analysis of Plk1 expression was performed in the pre-treatment tumour specimens from 75 rectal cancer patients. We analysed the assocation between Plk1 expression and clinicopathological parameters, pathologic response and outcome. Opposed to previous reports on this issue, low expression of Plk1 was significantly associated with a high grade of differentiation (P=0.0007) and higher rate of distant metastasis (P=0.014). More importantly, decreased levels of Plk1 were associated with absence of response after neoadjuvant therapy (P=0.049). Moreover, low Plk1 expression emerged as an unfavourable prognostic factor for disease-free survival in the non-responder group of patients (P=0.037). CONCLUSIONS: Decreased Plk1 expression was associated with poor pathologic response and worse disease-free survival in rectal cancer patients receiving neoadjuvant chemoradiotherapy, suggesting Plk1 as a clinically relevant marker to predict chemoradiotherapy response and outcome. PMID- 27712976 TI - A rare, low-grade appendiceal mucinous neoplasm (Pseudomyxoma peritonei) with ossification: A case report with morphoproteomic analysis of bone formation. AB - Heterotopic ossification occurring to low-grade appendiceal mucinous neoplasm (LAMN) (pseudomyxoma peritonei) is extremely rare. The pathogenetic mechanism of the tumor-related heterotopic bone formation remains as yet unconfirmed. Here, we describe a rare case of LAMN with ossification in a 72-year-old woman, and concentrate on the etiology of heterotopic ossification by the immunohistochemical evaluation of the novel markers such as BMP9, osteocalcin, and osteopontin. BMP9 is one of the most effective osteogenetic proteins. However, no researches associated with BMP9 in the heterotopic ossification occurring to LAMN have been performed. Consequently, we suggest the trustworthy hypothesis of tumor-associated heterotopic bone formation through this case. When osteoblastic markers such as BMP9, osteocalcin, and osteopontin are overexpressed in tumor cells, osteoblast-like transformation of such tumor cells occurs. In turn, these tumor cells increase secretion of interactive osteogenetic factors, such as BMP9, osteocalcin, and osteopontin, thus contributing to heterotopic bone formation through a microenvironmental change to mesenchymal stromal cells (osteoblastic differentiation). This phenomenon is considered a type of EMT. Patients should be followed closely because EMT-like transformed tumors have shown a tendency toward local recurrence. Our findings provide insight into the pathogenetic etiology of the heterotopic ossification in LAMN (pseudomyxoma peritonei). PMID- 27712977 TI - Breast cancer in young women of Chinese Han population: A retrospective study of patients under 25 years. AB - BACKGROUND: Breast cancer has aggressive clinical and pathological features in younger women and is characterized by poorer prognosis than in older women. However, data on women <25 years are limited. OBJECTIVE: The aim of the present study was to evaluate the different pathological characteristics and prognostic factors in Chinese women with breast cancer <25 years at the time of diagnosis. METHODS: This retrospective study included 94 patients (aged <25) of Chinese Han population with operable breast cancer at the National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences between January 1, 2000 and September 30, 2015. Univariate and multivariate Cox regression analysis were performed. The median follow-up duration was 64 months (range, 11-200 months). RESULTS: The HER2-positive and triple-negative groups had a higher T (P=0.002) and N stage than the luminal A group (P=0.014). The 5-year overall survival (OS) was 90.4%, and the disease-free survival (DFS) was 74.5%. The 5-year DFS varied among the four groups were 94.1 vs. 76.9 vs. 45.5 vs. 66.7%, respectively; P=0.009. Multivariate analysis showed that only estrogen receptor (ER) status was a significant predictor of OS and DFS [Hazard ratio (HR)=5.3, 95% confidence interval (CI)=1.11-25.27, P=0.036; HR=2.712, 95%CI=1.27-5.80, P=0.01). CONCLUSION: HER2-positive and triple-negative breast cancer are more likely to have poor prognosis in patients<25years. Hence, ER status may be identified as an independent prognostic factor for predicting young women with breast cancer. PMID- 27712978 TI - MMP-14 promotes VSMC migration via up-regulating CD44 expression in cardiac allograft vasculopathy. AB - Cardiac allograft vasculopathy (CAV) was the leading cause of late death in heart transplantation recipients. Matrix metalloproteinase-14 (MMP-14), as a member of the MMPs family, has been reported to play a vital role in coronary vascular lesions of allotransplanted hearts. However, concrete mechanism is still unclear. Herein, we showed that the expression of MMP-14 was different between isografts and allografts. Interestingly, we found MMP-14 could interact with CD44 in allografts. Cluster of differentiation 44 (CD44), as a cell adhesion receptor and is involved in cell migration, caused our interest in MMP-14/CD44 complex in allografts. Then we analyzed the effect of MMP-14/CD44 complex on pro-MMP-9 activation and vascular smooth muscle cell (VSMC) migration in rat VSMC TNF-alpha treated model. Then, we further found intervention of MMP-14/CD44 complex could inhibit VSMC migration. Our results elucidate the molecular mechanism of VSMC migration after cardiac transplantation and provide theoretical basis for seeking new specific drug targets for CAV prevention and treatment. PMID- 27712979 TI - Novel polyacrylate-based cationic nanoparticles for survivin siRNA delivery combined with mitoxantrone for treatment of breast cancer. AB - As a gene delivery method in breast cancer therapy, knocking down the undesired genes in the cancerous cells would be promising. Inhibitors of Apoptosis Protein (IAP) family genes are some of the genes whose responsibility is inhibition of apoptosis in cells. Silencing these genes seems to be helpful directing the tumor cells to death. siRNA sequence designed against survivin anti-apoptotic gene can play this role if carried to the cytoplasm. Here we prepared a positive charged biocompatible nano-sized particle made up of a Fe3O4 core covered respectively by polyacrylate (PA) and polyethyleneimine (PEI) layer, which could successfully deliver the siRNA into the MCF-7 cells. The particle structure was checked and having less than 50 nm diameter in size, positive charge and, safety towards MCF 7 cells besides being able to form nanoplexes with the siRNA strand helps it entering into the biologic assays part. The siRNA delivery evaluated via flowcytometry. Apoptosis induction was determined by DAPI staining. The efficiency of survivin gene knockdown was evaluated in mRNA and protein levels using Real time PCR and western blotting methods. Overall, the Fe3O4-PA-PEI nanoparticles can deliver siRNA effectively into the cytoplasm of the MCF-7 breast cancer cells and induce apoptosis. PMID- 27712980 TI - Resampling: An improvement of importance sampling in varying population size models. AB - Sequential importance sampling algorithms have been defined to estimate likelihoods in models of ancestral population processes. However, these algorithms are based on features of the models with constant population size, and become inefficient when the population size varies in time, making likelihood based inferences difficult in many demographic situations. In this work, we modify a previous sequential importance sampling algorithm to improve the efficiency of the likelihood estimation. Our procedure is still based on features of the model with constant size, but uses a resampling technique with a new resampling probability distribution depending on the pairwise composite likelihood. We tested our algorithm, called sequential importance sampling with resampling (SISR) on simulated data sets under different demographic cases. In most cases, we divided the computational cost by two for the same accuracy of inference, in some cases even by one hundred. This study provides the first assessment of the impact of such resampling techniques on parameter inference using sequential importance sampling, and extends the range of situations where likelihood inferences can be easily performed.

AB - The development of genome-wide massively parallel sequencing, ie, whole-genome and whole-exome sequencing, and copy number approaches has raised high expectations for the identification of novel hereditary colorectal cancer genes. Although relatively successful for genes causing adenomatous polyposis syndromes, both autosomal dominant and recessive, the identification of genes associated with hereditary non-polyposis colorectal cancer has proven extremely challenging, mainly because of the absence of major high-penetrance genes and the difficulty in demonstrating the functional impact of the identified variants and their causal association with tumor development. Indeed, most, if not all, novel candidate non-polyposis colorectal cancer genes identified so far lack corroborative data in independent studies. Here we review the novel hereditary colorectal cancer genes and syndromes identified and the candidate genes proposed in recent years as well as discuss the challenges we face.

AB - OBJECTIVE: To characterize the conditions of quality of working life, the presence of muscle- skeletal disorders and the association between these variables in nursing staff of a public hospital in Zacatecas, Mexico. METHOD: A cross-sectional study with descriptive-correlational scope was designed. A stratified random sampling per shift was used in 107 cases. The Questionnaire Professional Quality of Life (CVP-35) was applied as well as the Nordic Questionnaire Standardized for musculoskeletal pain and work-related risk factors questionnaire. RESULTS: The quality of working life gained an average of 55.62 (SD=13.57), the intrinsic motivation was the best rated component with (M=75.06, SD=18.44), contrary to managerial support that got the lowest scores with (M=43.74, SD=21.71). The presence of risk factors in the development work of musculoskeletal problems obtained a mean of 50.10 (SD=26.69). The main musculoskeletal disorders occurred in the neck region, lumbar spine and knees with 42.1% for each one. The quality of working life decreased in the presence of muscle-skeletal problems in the lumbar region with (-0.188, p<=.050), dorsal ( 0.206, p<=.050), neck (-0.175, p<=.050) and knees (-0.220, p<=.010). CONCLUSIONS: It is necessary to improve the working conditions of nurses to reduce the presence of musculoskeletal problems and improve their quality of working life. PMID- 27712986 TI - Increased Bone Mineral Density in Cervical or Thoracic Diffuse Idiopathic Skeletal Hyperostosis (DISH): A Case-Control Study. AB - We aim to compare the bone mineral density (BMD) in a group of patients with cervical or thoracic diffuse idiopathic skeletal hyperostosis (DISH) with that in a matched control group. We also investigated the prevalence of osteoporosis in the two groups and determined the correlation between BMD and the extent of spinal DISH. From 1999 to July 2015, 65 patients with DISH underwent dual-energy X-ray absorptiometry at our institute. The control group was matched with regard to age, sex, and body mass index to the patient group on a 1:1 basis. BMD was measured at the lumbar spine (L1-L4), femur neck, and femur total areas using dual-energy X-ray absorptiometry. The BMDs of the DISH and control groups were significantly different at the lumbar spine (L1-L4) and the femur neck (p = 0.005, 0.001). The rates of patients with osteopenia and osteoporosis were lower in the DISH than in the control group for the lumbar spine (L1-L4) (p = 0.05). A positive correlation was observed between the lumbar spine (L1-L4) BMD and the number of spine levels affected by DISH (p = 0.04). The BMDs of the lumbar spine and femur neck were found to be higher in the DISH group than in a matched control group, when patients with lumbar DISH involvement were excluded. The rates of osteopenia and osteoporosis tended to be lower in the DISH group than in the control group. Lumbar spine BMD is significantly correlated with the number of spine levels affected by DISH.

AB - Determination of cardiac troponin I (cTnI) is one central means for diagnosis of myocardial infarction. Assay performance of three troponin I assays was compared previously in a large reference population detecting sex-differences in the 99th percentile only for the Dimension Vista cTnI assay. The present study examined the underlying effects. Values for cTnI were reused. Creatine kinase (CK) activity was determined in 2358 samples from blood donors. Information on physical activity was evaluated from health questionnaires. Using quantile regression data were analysed to investigate the impact of sex, physical activity, and CK on the 99th percentile of the cTnI assay. We report significant sex-differences for the 99th percentile of cTnI. Physical activity was significantly associated with cTnI values. Strong association of CK activity with cTnI values was detected only in men. Adjustment for CK in quantile regression abolished sex-differences in the 99th percentile. Two other contemporary sensitive cTnI assays were not relevantly affected by physical activity or CK. Sex-differences in the 99th percentile for the Dimension Vista cTnI assay arise from a positive association between cTnI and physical activity and were abrogated when data were adjusted for CK activity. These findings should be taken into account when using this assay. PMID- 27712988 TI - Estimated glomerular filtration rate calculated using different creatinine and cystatin based formulas in prediction of trough plasma Dabigtran concentration. AB - BACKGROUND: In this paper we evaluated the relationship between trough DAB concentration with eGFR calculated using CRE and CYS based formulas. MATERIALS AND METHODS: We considered 100 patients. eGFR was calculated using CKD-EPIcreat, CG, MDRD, CKD-EPIcys and CKD-EPIcombined equations. DAB dosage was selected on the basis of CKD-EPIcreat and relationship between trough DAB concentration and eGFRs was evaluated. RESULTS: Trough DAB concentration roughly correlates with eGFR calculated using various formulas. CKD-EPIcreat eGFR was higher than CKD EPIcys. In patients receiving a DAB dosage considered adequate using CKD-EPIcreat eGFR but considered excessive using CKD-EPIcys, we observed higher DAB trough concentration and an increased prevalence of subjects with drug concentration >200ng/mL. CONCLUSION: These results suggest that eGFR alone was unable to fully explain trough DAB plasma concentration. Therefore a drug's prescription schedule based on eGFR only should be inadequate. We observed a better correlation between trough DAB concentration and CKD-EPIcys rather than CKD-EPIcreat eGFR. Thus, in patients chronically treated with DAB for thromboprophylaxis in nonvalvular atrial fibrillation evaluation of eGFR using a cystatin base formula should be considered.

It also contributes competing saturation transfer pathways in T1-exchange spectroscopy, and the determination of paramagnetic relaxation enhancement in site-directed spin labelling. A survey shows that the definition of nitrogen nuclear relaxation rate Wn commonly used in the CW-EPR literature for 14N nitroxyl spin labels is inconsistent with that currently adopted in time-resolved EPR measurements of saturation recovery. Redefinition of the normalised 14N spin lattice relaxation rate, b=Wn/(2We), preserves the expressions used for CW-EPR, whilst rendering them consistent with expressions for saturation recovery rates in pulsed EPR. Furthermore, values routinely quoted for nuclear relaxation times that are deduced from EPR spectral diffusion rates in 14N-nitroxyl spin labels do not accord with conventional analysis of spin-lattice relaxation in this three level system. Expressions for CW-saturation EPR with the revised definitions are summarised. Data on nitrogen nuclear spin-lattice relaxation times are compiled according to the three-level scheme for 14N-relaxation: T1n=1/Wn. Results are compared and contrasted with those for the two-level 15N-nitroxide system. PMID- 27712990 TI - Influence of concurrency, partner choice, and viral suppression on racial disparity in the prevalence of HIV infected women. AB - In 1992, Watts and May introduced a simple dynamical systems model of the spread of HIV based on disease transmission per partnership including the length of partnership duration. This model allowed for the treatment of concurrent partnerships, although it was hampered by the assumption of an important latent phase which generated a non-autonomous system. Subsequent models including concurrency have been based on networks, Monte Carlo, and stochastic simulations which lose a qualitative understanding of the effects of concurrency. We present a new autonomous deterministic model of the effect of concurrent sexual partnerships that allows for an analytical study of disease transmission. We incorporate the effect of concurrency through the newly derived force of infection term in a mathematical model of the transmission of HIV through sexual contact in a population stratified by sexual behavior and race/ethnicity. The model also includes variations in population mixing (partner choice) and non uniform Highly Active Anti-Retroviral Treatment (HAART) leading to viral suppression. We use this mathematical model to understand the non-uniform spread of HIV in women who were infected through heterosexual contact. In addition, an analytical study shows the importance of continued condom use in virally suppressed MSM. Numerical simulations of the reproduction number as a function of concurrency, viral suppression level, and mixing show a reservoir of disease present in both heterosexual and MSM populations. Statistical analysis of parameter values show that viral suppression level, mixing and progression to AIDS without viral suppression have a strong correlation (either positive or negative) with the number of HIV positive women. Concurrency and assortative mixing are shown to be essential to reproduce infection levels in women, as reported by 2010 data from the Center for Disease Control (CDC). PMID- 27712991 TI - Sensitivity and elasticity analysis of a Lur'e system used to model a population subject to density-dependent reproduction. AB - Sensitivity and elasticity analyzes have become central to the analysis of models in population biology and ecology. While much work has been done applying sensitivity and elasticity analysis to study density-independent (linear) matrix and integral projection models, little work has been done to study the sensitivity and elasticity of density-dependent models, especially integral projection models. In this paper we derive sensitivity and elasticity formulas for the equilibrium population n* of a structured population modeled by a Lur'e system, which consists of a linear system plus a nonlinearity modeling density dependent fecundity. Sensitivity and elasticity formulas are easy to interpret ecologically, and we apply these formulas to published models for Chinook Salmon and Platte thistle (Cirsium canescens). In the C. canescens example we show that models with identical equilibrium populations can have sensitivities that are an order-of-magnitude apart, depending on the functional form for the nonlinearity. PMID- 27712992 TI - Smartphone-based sensing system using ZnO and graphene modified electrodes for VOCs detection. AB - Volatile organic compounds (VOCs) detection is in high demand for clinic treatment, environment monitoring, and food quality control. Especially, VOCs from human exhaled breath can serve as significant biomarkers of some diseases, such as lung cancer and diabetes. In this study, a smartphone-based sensing system was developed for real-time VOCs monitoring using alternative current (AC) impedance measurement. The interdigital electrodes modified with zinc oxide (ZnO), graphene, and nitrocellulose were used as sensors to produce impedance responses to VOCs. The responses could be detected by a hand-held device, sent out to a smartphone by Bluetooth, and reported with concentration on an android program of the smartphone. The smartphone-based system was demonstrated to detect acetone at concentrations as low as 1.56ppm, while AC impedance spectroscopy was used to distinguish acetone from other VOCs. Finally, measurements of the exhalations from human being were carried out to obtain the concentration of acetone in exhaled breath before and after exercise. The results proved that the smartphone-based system could be applied on the detection of VOCs in real settings for healthcare diagnosis. Thus, the smartphone-based system for VOCs detection provided a convenient, portable and efficient approach to monitor VOCs in exhaled breath and possibly allowed for early diagnosis of some diseases.

PMID- 27712994 TI - Identification of high-affinity anti-CD16A allotype-independent human antibody domains. AB - CD16A (FcgammaRIIIA) is an activating receptor mostly expressed on natural killer (NK) cells and monocytes/macrophages. It can mediate antibody-dependent cell mediated cytotoxicity (ADCC) through low-affinity interaction with human immunoglobulin G (IgG) Fc. It can also mediate cell lysis if NK cells are guided by bispecific killer cells engagers (BiKEs). BiKEs showed some success in clinical trials of cancer and are promising candidate therapeutics. However, currently reported BiKEs are based on antibody fragments (scFvs) of relatively large size. The CD16A-specific antibodies are also typically from animal origin. Decreasing the BiKE size could result in enhanced penetration into solid tumor and normal tissues, and using fully human antibodies could decrease the likelihood of immunogenicity. Here we report the identification and characterization of two antibody domains, D6 and E11, isolated from a very large human VH antibody domain library displayed on phage. D6 and E11 bound CD16A with EC50 of 4nM and 8nM, respectively, but not other Fc gamma receptors (FcgammaRs) such as CD64 (FcgammaRI), CD32 (FcgammaRII) and CD16B (FcgammaRIIIB). They bound to both CD16A allotypes (158F,V) with equal affinity and competed with each other as well as with human IgG1 and the mouse anti-CD16A antibody 3G8. These and other results were used to build a molecular docking model predicting that D6 and E11 may bind to the CD16A membrane proximal D2 domain by interacting with its BC, C'E and EF loops. Importantly, cross-linked (bivalent) D6 and E11 induced secretion of IL-2 after binding to CD16A-expressing Jurkat T cells. The small size of these antibody domains combined with their high-affinity, specific, allotype independent, activating interactions with CD16A could allow generation of novel highly effective BiKEs and other candidate protein therapeutics.

PMID- 27712997 TI - Revisiting secondary capsulotomy for posterior capsule management in pediatric cataract surgery. AB - PURPOSE: To evaluate the development and treatment of visual axis opacification following pediatric cataract extraction with intraocular lens placement (IOL) without primary posterior capsulotomy and anterior vitrectomy (PPC+AV). METHODS: The medical records of children who underwent cataract extraction and IOL at an academic medical center were reviewed retrospectively for development of posterior capsular opacification (PCO) to identify risk factors for development of treatment-requiring posterior capsular opacification. RESULTS: A total of 63 eyes of 47 children 7 months to 16 years of age were included. The rate of PCO formation following cataract extraction without PPC+AV was 90%. Of those, 96% required a secondary capsular procedure to clear the visual axis; 55% had a clear visual axis after 1 procedure, almost exclusively with a YAG capsulotomy, and 3.5% did not require any secondary capsular procedure. Younger age was the only statistically significant characteristic associated with both PCO formation and need for more than one secondary capsular procedure. Children <3 years of age had an average of 2.1 capsular procedures. CONCLUSIONS: Cataract extraction and IOL without PPC+AV leads to an expected high rate of PCO formation, which can be effectively managed with a secondary capsular procedure in all age groups. Leaving the posterior capsule intact at primary surgery is an option to discuss with parents to avoid a more complicated primary surgery. PMID- 27712995 TI - Combination strategy of PARP inhibitor with antioxidant prevent bioenergetic deficits and inflammatory changes in CCI-induced neuropathy. AB - Neuropathic pain, a debilitating pain condition and the underlying pathogenic mechanisms are complex and interwoven amongst each other and still there is scant information available regarding therapies which promise to treat the condition. Evidence indicate that oxidative/nitrosative stress induced poly (ADP-ribose) polymerase (PARP) overactivation initiate neuroinflammation and bioenergetic crisis culminating into neurodegenerative changes following nerve injury. Hence, we investigated the therapeutic effect of combining an antioxidant, quercetin and a PARP inhibitor, 4-amino 1, 8-naphthalimide (4-ANI) on the hallmark deficits induced by chronic constriction injury (CCI) of sciatic nerve in rats. Quercetin (25 mg/kg, p.o.) and 4-ANI (3 mg/kg, p.o.) were administered either alone or in combination for 14 days to examine sciatic functional index, allodynia and hyperalgesia using walking track analysis, Von Frey, acetone spray and hot plate tests respectively. Malondialdehyde, nitrite and glutathione levels were estimated to detect oxidative/nitrosative stress; mitochondrial membrane potential and cytochrome c oxidase activity to assess mitochondrial function; NAD & ATP levels to examine the bioenergetic status and levels of inflammatory markers were evaluated in ipsilateral sciatic nerve. Quercetin and 4-ANI alone improved the pain behaviour and biochemical alterations but the combination therapy demonstrated an appreciable reversal of CCI-induced changes. Nitrotyrosine and Poly ADP-Ribose (PAR) immunopositivity was decreased and nuclear factor erythroid 2-related factor (Nrf-2) levels were increased significantly in micro-sections of the sciatic nerve and dorsal root ganglion (DRG) of treatment group. These results suggest that simultaneous inhibition of oxidative stress-PARP activation cascade may potentially be useful strategies for management of trauma induced neuropathic pain. PMID- 27712999 TI - Evaluation of the cytotoxic, apoptosis inducing activity and molecular docking of spiroquinazolinone benzamide derivatives in MCF-7 breast cancer cells. AB - Previous studies have suggested that quinazolinone derivatives are potent apoptosis-inducing agents in various cancer cell lines. In the present study, we have investigated cytotoxic, apoptosis induction, and molecular docking activities of the spiroquinazolinone benzamide derivatives family on MCF-7 human breast cancer cells. The MTT cytotoxicity assays and docking studies showed that 4t-CHQB was the most active compound among the prepared spiroquinazolinone benzamide compounds with IC50 of 50 +/- 1.2 MUM and was selected for further assessments. Apoptosis, as the mechanism of cell death, was assessed morphologically by acridine orange/ethidium bromide (AO/EtBr) double staining, evaluation of the cell surface phosphatidylserine (PS) expression through annexin V/PI technique and, the formation of DNA ladder. Down regulation of survivin was evaluated in protein level after cell treatment with 4t-CHQB using western blotting method. Molecular modeling experiments involving 4t-CHQB binding site of survivin showed several strong hydrogen bonds and hydrophobic interactions between many important amino acid residues. Overall, the obtained data suggest that the assessed spiroquinazolinone benzamide compounds may provide a novel therapeutic approach for further evaluation, as an effective chemotherapeutic family acting through down regulation of survivin and apoptosis induction in breast cancer. PMID- 27713000 TI - Overlapping effects of age on associative memory and the anterior hippocampus from middle to older age. AB - The anterior hippocampus has been implicated in associative memory, and along with hippocampal volume, this type of memory declines with age. However, few cross-sectional studies include middle-aged samples, making it unclear at what point these age-related changes occur. In addition, although men and women have been shown to differ in associative memory and rates of age-related hippocampal atrophy, sex-differences in aging are rarely studied. To address these issues, we assessed memory for word-pairs, hippocampal volume and activation during encoding and retrieval, across middle-aged (n=39) and older (n=44) participants, specifically in relation to sex. Older adults showed significantly poorer associative memory compared to middle-aged adults, paralleled by smaller anterior hippocampi and less activation during successful retrieval. The age-by-sex interaction observed in memory performance was also mirrored in the volume and activation of the hippocampus, indicating more pronounced age-effects in men as compared to women. These results indicate a specific role of the anterior hippocampus in verbal associative memory and suggest they both decline between middle-age and older age. PMID- 27712998 TI - Inhibitors of retrograde trafficking active against ricin and Shiga toxins also protect cells from several viruses, Leishmania and Chlamydiales. AB - Medical countermeasures to treat biothreat agent infections require broad spectrum therapeutics that do not induce agent resistance. A cell-based high throughput screen (HTS) against ricin toxin combined with hit optimization allowed selection of a family of compounds that meet these requirements. The hit compound Retro-2 and its derivatives have been demonstrated to be safe in vivo in mice even at high doses. Moreover, Retro-2 is an inhibitor of retrograde transport that affects syntaxin-5-dependent toxins and pathogens. As a consequence, it has a broad-spectrum activity that has been demonstrated both in vitro and in vivo against ricin, Shiga toxin-producing O104:H4 entero-hemorrhagic E. coli and Leishmania sp. and in vitro against Ebola, Marburg and poxviruses and Chlamydiales. An effect is anticipated on other toxins or pathogens that use retrograde trafficking and syntaxin-5. Since Retro-2 targets cell components of the host and not directly the pathogen, no selection of resistant pathogens is expected. These lead compounds need now to be developed as drugs for human use. PMID- 27713001 TI - Levo-tetrahydropalmatine inhibits the acquisition of ketamine-induced conditioned place preference by regulating the expression of ERK and CREB phosphorylation in rats. AB - Levo-tetrahydropalmatine (l-THP) is an alkaloid purified from the Chinese herbs Corydalis and Stephania and has been used in many traditional Chinese herbal preparations for its sedative, analgesic and hypnotic properties. Previous studies demonstrated that l-THP has antagonistic activity on dopamine receptors; thus, it may have potential therapeutic effects on drug abuse. However, whether l THP affects ketamine-induced conditioned place preference (CPP) remains unclear. Therefore, the present study was designed to evaluate the effects of l-THP on the rewarding behavior of ketamine through CPP. Results revealed that ketamine (5, 10 and 15mg/kg) induced CPP in rats. Furthermore, Ketamine (10mg/kg) promoted the phosphorylation of extracellular-regulated kinase (ERK) and cAMP responsive element binding protein (CREB) in the hippocampus (Hip) and caudate putamen (CPu), but not in the prefrontal cortex (PFc). l-THP (20mg/kg) co-administered with ketamine during conditioning inhibited the acquisition of ketamine-induced CPP in rats. Furthermore, l-THP (20mg/kg) prevented the enhanced phosphorylation of ERK and CREB in CPu and Hip. These results suggest that l-THP has potential therapeutic effects on ketamine-induced CPP. The underlying molecular mechanism may be related to its inhibitory effect on ERK and CREB phosphorylation in Hip and CPu. The present data supports the potential use of l-THP for the treatment of ketamine addiction. PMID- 27713002 TI - Sex differences in angiotensin II responses contribute to a differential regulation of cox-mediated vascular dysfunction during aging. AB - Aging is a cardiovascular risk factor partially related to activation of the Renin-Angiotensin System (RAS). RAS activation is also influenced by sex. In this regard, our study aims to determine whether sex-associated differences in RAS contribute to a differential regulation of vascular aging and associated dysfunction. Male and female outbreed CD-1 mice were studied at 3 and 12months of age (M). Contribution of RAS was determined by treating mice from 3M to 12M with the AngII type 1 receptor blocker losartan (0.6g/L in the drinking water). At 12M, contractions to AngII were higher in males compared to females (P<0.05). This effect was paralleled by a decrease in AngII type 2 receptors in 12M males. Aging also diminished ACh relaxation in males, but did not modify female responses. Treatment of aortas with indomethacin (10MUM) restored the impaired endothelium-dependent relaxation in 12M males, suggesting an increase of cyclooxygenase (COX)-derived vasoconstrictors in aged males. Chronic treatment of mice with losartan also improved endothelium-dependent relaxation. Besides, losartan significantly decreased COX-2 expression and activity in 12M male, with a minor effect in aged females. Aging increases AngII contraction and induces endothelial dysfunction differently in males and females. In aged males, RAS contributed to increased COX-2 expression and activity, which in turn may lead to vascular dysfunction. PMID- 27713003 TI - Diacylglycerol kinase epsilon suppresses expression of p53 and glycerol kinase in mouse embryo fibroblasts. AB - The incorporation of glycerol into lipid was measured using SV40 transformed mouse embryo fibroblasts (MEFs) from either wild-type (WT) mice or from mice in which the epsilon isoform of diacylglycerol kinase (DGKepsilon) was knocked out (DGKepsilon-/-). We present an explanation for our finding that DGKepsilon-/- MEFs exhibited greater uptake of 3H-glycerol into the cell and a greater incorporation into lipids compared with their WT counterparts, with no change in the relative amounts of various lipids between the DGKepsilon-/- and WT MEFs. Glycerol kinase is more highly expressed in the DGKepsilon-/- cells than in their WT counterparts. In addition, the activity of glycerol kinase is greater in the DGKepsilon-/- cells than in their WT counterparts. Other substrates that enter the cell independent of glycerol kinase, such as pyruvate or acetate, are incorporated into lipid to the same extent between DGKepsilon-/- and WT cell lines. We also show that expression of p53, a transcription factor that increases the synthesis of glycerol kinase, is increased in DGKepsilon-/- MEFs in comparison to WT cells. We conclude that the increased incorporation of glycerol into lipids in DGKepsilon-/- cells is a consequence of up-regulation of glycerol kinase and not a result of an increase in the rate of lipid synthesis. Furthermore, increased expression of the pro-survival gene, p53, in cells knocked out for DGKepsilon suggests that cells over-expressing DGKepsilon would have a greater propensity to become tumorigenic. PMID- 27713005 TI - Deep sedation without intubation during second trimester surgical termination in an inpatient hospital setting. AB - OBJECTIVES: Safety of outpatient dilation and evacuations with intravenous (iv) sedation without intubation has been demonstrated, but there is a paucity of data on deep iv sedation on an inpatient second trimester surgical termination population. The purpose of this study is to evaluate complications of deep sedation with propofol without the use of intubation during second trimester surgical terminations in an inpatient teaching institution. STUDY DESIGN: A retrospective chart review of all obstetrical and anesthetic data from inpatient dilation and evacuations between gestational ages 15 0/7 and 24 0/7 during the years 2002 to 2015. We examined 332 patient charts. Primary outcomes included suspected perioperative pulmonary aspiration and conversion to an intubated general anesthesia. RESULTS: No perioperative pulmonary aspiration cases were either suspected or confirmed. There were a total of 14 (4.2%) patients that had intubation compared to 313 with natural airway (94.3%) or laryngeal mask (1.5%). Of the 14 intubated, 9 (64%) were started with intubation, and 5 (36%) were converted during the procedure (1.7% of those started with nonintubated anesthesia). Cases requiring intubation were associated with longer procedure times (p=<0.001), higher American Society of Anesthesiologists (ASA) class (p=0.038), greater estimated blood loss (p=<0.001) and a primary indication of maternal health (p=<0.001) for the dilation and evacuation. CONCLUSIONS: Deep sedation without intubation appears safe in a hospital setting with few complications reported. IMPLICATIONS: Deep sedation without intubation for operating room dilation and evacuation is a safe option that rarely resulted in conversion to intubation and, in most cases, should be the anesthesia method of choice at initiation in an inpatient setting. PMID- 27713006 TI - Medical exchange with Japan and the UK. PMID- 27713004 TI - Biological and pathophysiological roles of end-products of DHA oxidation. AB - BACKGROUND: Polyunsaturated fatty acids (PUFA) are known to be present and/or enriched in vegetable and fish oils. Among fatty acids, n-3 PUFA are generally considered to be protective in inflammation-related diseases. The guidelines for substituting saturated fatty acids for PUFAs have been highly publicized for decades by numerous health organizations. Recently, however, the beneficial properties of n-3 PUFA are questioned by detailed analyses of multiple randomized controlled clinical trials. The reported heterogeneity of results is likely due not only to differential effects of PUFAs on various pathological processes in humans, but also to the wide spectrum of PUFA's derived products generated in vivo. SCOPE OF REVIEW: The goal of this review is to discuss the studies focused on well-defined end-products of PUFAs oxidation, their generation, presence in various pathological and physiological conditions, their biological activities and known receptors. Carboxyethylpyrrole (CEP), a DHA-derived oxidized product, is especially emphasized due to recent data demonstrating its pathophysiological significance in many inflammation-associated diseases, including atherosclerosis, hyperlipidemia, thrombosis, macular degeneration, and tumor progression. MAJOR CONCLUSIONS: CEP is a product of radical-based oxidation of PUFA that forms adducts with proteins and lipids in blood and tissues, generating new powerful ligands for TLRs and scavenger receptors. The interaction of CEP with these receptors affects inflammatory response, angiogenesis, and wound healing. GENERAL SIGNIFICANCE: The detailed understanding of CEP-mediated cellular responses may provide a basis for the development of novel therapeutic strategies and dietary recommendations.

PMID- 27713008 TI - CT-based morphological analysis of spinal fractures in patients with diffuse idiopathic skeletal hyperostosis. AB - PURPOSE: To clarify correlations between spinal fracture and delayed paralysis in patients with diffuse idiopathic skeletal hyperostosis (DISH) using computed tomography (CT) with multiplanar reformatting (CT-MPR). DISH increases susceptibility to unstable spinal fractures, leading to neurological deterioration. The pathomechanism of the neurological injury is unclear. METHODS: This multicenter retrospective study included 42 DISH patients (32 male; 10 female) treated for 45 spinal fractures during a 5-year period. The mean age at the time of injury was 77.1 +/- 10.1 years. The cause of injury, delay in diagnosis, fracture location, and neurological status were recorded, and anterior and posterior-column fractures, a fracture displacement over 3 mm, and posterior column ankylosis were assessed using CT-MPR. RESULTS: Most fractures (73.8%) resulted from trivial trauma, such as falling from a standing or sitting position. Diagnosis was delayed in 47.6% of the patients, primarily due to delays in seeking medical attention (65.0%). Although 78.6% of the patients were neurologically intact at the time of injury, 54.8% developed paralysis, defined by a change in one or more Frankel-score levels during short-term follow-up. Of the fractures, 39.1% were in the vertebral body, and 60.9% were at the disc level. Fractures with posterior-column ankylosis were significantly associated with delayed paralysis. CONCLUSIONS: CT-MPR was useful for evaluating spinal fractures and determining treatment in patients with DISH. Fractures associated with posterior-column ankylosis resulted in unstable three-column injuries that led to delayed neurological deterioration. Early surgical stabilization of such fractures is recommended to avoid delayed paralysis. PMID- 27713009 TI - Cervical spinal canal stenosis first presenting after spinal cord injury due to minor trauma: An insight into the value of preventive decompression. AB - PURPOSE: Patients with pre-existing cervical spinal canal stenosis (CSCS) may have minimal or no symptoms. However, performing preventive decompression is controversial as the incidence of CSCS leading to severe cord injury is unknown. Hence, this study aims to revisit the threshold for surgery in "silent" CSCS by reviewing the neurologic outcomes of patients with undiagnosed CSCS who sustained a cervical spinal cord injury (CSCI). METHODS: Two groups of subjects were recruited for analysis. Firstly, patients with trauma-induced CSCI without fracture or dislocation were included. Pre-existing CSCS was diagnosed by MRI measurements. The second group consisted of asymptomatic subjects recruited from the general population who also had MRIs performed. Canal sizes were compared between this control group and the patient group. Within the patient group, neurological assessments and outcomes by Frankel classification were performed in patients treated surgically or conservatively. RESULTS: 32 patients with CSCS were recruited. The mean spinal canal sagittal diameter (disc-level) of all CSCS cases was 5.3 +/- 1.4 mm (1.3-8.2). In comparison, the diameter was 10.5 +/- 1.7 mm (6.6-14.6) in the 47 asymptomatic individuals recruited from the general population. Decompression was performed in 17 patients and conservative treatment in 15. Mean follow-up was 19.3 +/- 17.0 months (6-84). At the final follow-up, 3 patients (9.3%) returned to their pre-injury Frankel grade, whereas 26 patients (83.3%) lost one or more neurological grade. Three patients (9.3%) died. CONCLUSIONS: Majority of patients with "silent" CSCS who sustained cervical cord injuries did not return to their pre-injury neurological status. All of these subjects have pre-existing canal stenosis hence the risk of cord injury. Given the poor neurological outcome of CSCS, a lower threshold for surgery could be indicated to avoid these disastrous injuries. However, before making any conclusive recommendation we must first identify the prevalence of "silent" CSCS in the general population and the risk of developing spinal cord injury with more prospective population-based studies. PMID- 27713010 TI - Phosphorylated Codonopsis pilosula polysaccharide could inhibit the virulence of duck hepatitis A virus compared with Codonopsis pilosula polysaccharide. AB - To screen effective anti-duck hepatitis A virus (DHAV) drugs, we applied STMP STPP method to prepare phosphorylated Codonopsis pilosula polysaccharide (pCPPS), the phosphorylation-modified product of Codonopsis pilosula polysaccharide (CPPS). The IR spectrum and field emission scanning electron microscope (FE-SEM) were subsequently used to analyze the structure of pCPPS. Several tests were conducted to compare the anti-DHAV activities of CPPS and pCPPS. The MTT method was used to compare the effect of the drugs on DHAV-infected duck embryonic hepatocytes (DEHs), and the Reed-Muench assay was employed to observe changes in the virulence of DHAV. We also applied real-time PCR to examine the relationship between virus replication and the expression of IFN-beta. The results indicated that CPPS could not inhibit the replication of DHAV. In contrast, pCPPS increased the virus TCID50, inhibited viral replication and, accordingly, increased the survival rate of DEHs infected with DHAV. Because DHAV induced the expression of IFN-beta, and the IFN-beta expression level was positively associated with the number of DHAV, the reduction of IFN-beta expression levels after pCPPS treatment demonstrated a decrease in the number of virus particles. These results indicated that pCPPS, which reduces the number of DHAV, was more effective than CPPS in anti-DHAV activity.

AB - In this study, the effect of the enrichment of rice starch with metal ions on its capability to generate free radicals during microwave processing was investigated. The underlying mechanism was explored from two aspects: dielectric and thermal properties. Rice starch was modified with ions of iron, copper, manganese and calcium. The modified starches were analyzed in terms of dielectric properties, activation energy (Ea) and thermodynamic characteristics of gelatinization. The quantity and character of the free radicals were analyzed using electron paramagnetic resonance (EPR). The results showed that the metal ions could change the dielectric property and inter structure of rice starch, thus influencing the ability of rice starch to generate radicals under microwave irradiation.

AB - Central infusion of Insulin-Regulated Aminopeptidase (IRAP) inhibitors improves memory in both normal rodents and in models of memory deficit. However, in contrast, the global IRAP knockout mice (KO) demonstrate age-accelerated spatial memory deficits and no improvements in performance in any memory tasks. Potentially, the observed memory deficit could be due to the absence of IRAP in the developing brain. We therefore generated a postnatal forebrain neuron specific IRAP knockout mouse line (CamKIIalphaCre; IRAPlox/lox). Unexpectedly, we demonstrated that postnatal deletion of IRAP in the brain results in significant deficits in both spatial reference and object recognition memory at three months of age, although spatial working memory remained intact. These results indicate a significant role for IRAP in postnatal brain development and normal function of the hippocampus in adulthood. PMID- 27713014 TI - Synthesis and biological evaluation of furocoumarin derivatives on melanin synthesis in murine B16 cells for the treatment of vitiligo. AB - Furocoumarins, isolated from Psoralen corylifolia L., were found to be the most effective drug in the treatment of vitiligo nowadays. Twenty-five furocoumarin derivatives were thus designed and synthesized in order to improve the melanogenesis in B16 cells for the first time. Among them, twenty-three compounds were more potent than the positive control (8-MOP), the commonly used drug for vitiligo in clinic. Noticeably, compounds 6m (350.5%) and 6p (313.1%) based on the scaffold of 6k (2H-benzofuro[2,3-h]chromen-2-one) were nearly 3-fold stronger than 8-MOP (114.50%). The in vitro melanin synthesis evaluation of these structurally diverse analogues had also led to an outline of structure-activity relationship. PMID- 27713013 TI - Synthesis, photophysical properties and biological evaluation of beta alkylaminoporphyrin for photodynamic therapy. AB - A series of beta-alkylaminoporphyrins conjugated with different amines at beta position (D1-D3) or with electron-donating and electron-withdrawing substituents at phenyl position (D4-D6) were synthesized. Their photophysical and photochemical properties, intracellular localization, photocytotoxicities in vitro and vivo were also investigated. All target compounds exhibited no cytotoxicities in the dark and excellent photocytotoxicities against HeLa cells. Among them, D6 showed the highest phototoxicity and the lowest dark toxicity, which was more phototoxic than Hematoporphyrin monomethyl ether (HMME). In addition, D6 exhibited best photodynamic antitumor efficacy on BALB/c nude mice bearing HeLa tumor. Therefore, D6 is a powerful and promising antitumor photosensitizer for photodynamic therapy.

AB - Herein we report the synthesis, PDE-4B and TNF-alpha inhibitory activities of a few dibenzo[b,d]furan-1-yl-thiazole derivatives. The hydroxycyclohexanol amide derivatives 14, 18, 24, 29, 31 and 33 exhibited promising in vitro PDE-4B and TNF alpha inhibitory activities. Compound 24 showed good systemic availability in preclinical animal models and was also found to be non-toxic (exploratory mutagenicity test). Further it exhibited promising results in in vivo asthma/COPD and Uveitis models. PMID- 27713016 TI - A cell-based approach to characterize antimicrobial compounds through kinetic dose response. AB - The rapid spread of antibiotic resistance has created a pressing need for the development of novel drug screening platforms. Herein, we report on the use of cell-based kinetic dose response curves for small molecule characterization in antibiotic discovery efforts. Kinetically monitoring bacterial growth at sub inhibitory concentrations of antimicrobial small molecules generates unique dose response profiles. We show that clustering of profiles by growth characteristics can classify antibiotics by mechanism of action. Furthermore, changes in growth kinetics have the potential to offer insight into the mechanistic action of novel molecules and can be used to predict off-target effects generated through structure-activity relationship studies. Kinetic dose response also allows for detection of unstable compounds early in the lead development process. We propose that this kinetic approach is a rapid and cost-effective means to gather critical information on antimicrobial small molecules during the hit selection and lead development pipeline. PMID- 27713017 TI - Purification and characterization of d-allulose 3-epimerase derived from Arthrobacter globiformis M30, a GRAS microorganism. AB - An enzyme that catalyzes C-3 epimerization between d-fructose and d-allulose was found in Arthrobacter globiformis strain M30. Arthrobacter species have long been used in the food industry and are well-known for their high degree of safety. The enzyme was purified by ion exchange and hydrophobic interaction chromatographies and characterized as a d-allulose 3-epimerase (d-AE). The molecular weight of the purified enzyme was estimated to be 128 kDa with four identical subunits. The enzyme showed maximal activity and thermostability in the presence of Mg2+. The optimal pH and temperature for enzymatic activity were 7.0-8.0 and 70 degrees C, respectively. The enzyme was immobilized to ion exchange resin whereupon it was stable for longer periods than the free enzyme when stored at below 10 degrees C. In the column reaction, the enzyme activity also maintained stability for more than 4 months. Under these conditions, 215 kg of d-allulose produced per liter immobilized enzyme, and this was the highest production yield of d-allulose reported so far. These highly stable properties suggest that this enzyme represents an ideal candidate for the industrial production of d-allulose. PMID- 27713018 TI - Use of phylogenetical analysis to predict susceptibility of pathogenic Candida spp. to antifungal drugs. AB - Successful treatment of a Candida infection relies on 1) an accurate identification of the pathogenic fungus and 2) on its susceptibility to antifungal drugs. In the present study we investigated the level of correlation between phylogenetical evolution and susceptibility of pathogenic Candida spp. to antifungal drugs. For this, we compared a phylogenetic tree, assembled with the concatenated sequences (2475-bp) of the ATP2, TEF1, and TUF1 genes from 20 representative Candida species, with published minimal inhibitory concentrations (MIC) of the four principal antifungal drug classes commonly used in the treatment of candidiasis: polyenes, triazoles, nucleoside analogues, and echinocandins. The phylogenetic tree revealed three distinct phylogenetic clusters among Candida species. Species within a given phylogenetic cluster have generally similar susceptibility profiles to antifungal drugs and species within Clusters II and III were less sensitive to antifungal drugs than Cluster I species. These results showed that phylogenetical relationship between clusters and susceptibility to several antifungal drugs could be used to guide therapy when only species identification is available prior to information pertaining to its resistance profile. An extended study comprising a large panel of clinical samples should be conducted to confirm the efficiency of this approach in the treatment of candidiasis. PMID- 27713019 TI - Galleria mellonella hemocytes: A novel phagocytic assay for Leishmania (Viannia) braziliensis. AB - Galleria mellonella is an excellent invertebrate model for the study of diseases that involve interactions with cells from the innate immune system, since they have an innate immune system capable of recognizing the pathogens. Here we present for the first time, an alternative model for an in vitro phagocytic assay using hemocytes of G. mellonella larvae to study infection by Leishmania (Viannia) braziliensis. We showed that the insect phagocytic cells were able to engulf promastigotes. Furthermore, this infective form differentiated into the amastigote form inside those cells. However, the cells in this model seem resistant to the parasite, since amastigotes were depleted after 24h and NO levels were maintained after infection. Our model opens an avenue of possibilities for new investigations regarding other Leishmania species, mechanisms of invasion and evasion, receptors involved, release of signaling molecules and, above all, it is a novel infection model using invertebrate animals. PMID- 27713020 TI - Evaluation of urine for Leishmania infantum DNA detection by real-time quantitative PCR. AB - The availability of some sorts of biological samples which require noninvasive collection methods has led to an even greater interest in applying molecular biology on visceral leishmaniasis (VL) diagnosis, since these samples increase the safety and comfort of both patients and health professionals. In this context, this work aimed to evaluate the suitability of the urine as a specimen for Leishmania infantum kinetoplast DNA detection by real-time quantitative PCR (qPCR). Subsequent to the reproducibility analysis, the detection limit of the qPCR assay was set at 5fg (~0.025 parasites) per MUL of urine. From the comparative analysis performed with a set of diagnostic criteria (serological and molecular reference tests), concordance value of 96.08% was obtained (VL suspected and HIV/AIDS patients, n=51) (P>0.05). Kappa coefficient (95% CI) indicated a good agreement between the test and the set of diagnostic criteria (k=0.778+/-0.151). The detection of Leishmania DNA in urine by qPCR was possible in untreated individuals, and in those with or without suggestive renal impairment. Fast depletion of the parasite's DNA in urine after treatment (from one dose of meglumine antimoniate) was suggested by negative qPCR results, thus indicating it as a potential alternative specimen to follow up the efficacy of therapeutic approaches. Even when evaluated in a clinically heterogeneous set of patients, the urine showed good prospect as sample for VL diagnosis by qPCR, also indicating a good negative predictive value for untreated suspected patients. PMID- 27713021 TI - Disodium cromoglycate inhibits asthma-like features induced by sphingosine-1 phosphate. AB - Compelling evidence suggests the involvement of sphingosine-1-phosphate (S1P) in the pathogenesis of asthma. The systemic administration of S1P causes asthma like features in the mouse involving mast cells. In this study we investigated whether disodium cromoglycate (DSCG), administered as a preventative treatment as in human therapy, could affect S1P effects on airways. BALB/c mice, treated with DSCG, received subcutaneous administration of S1P. Bronchi and pulmonary tissues were collected and functional, molecular and cellular studies were performed. DSCG inhibited S1P-induced airway hyper-reactivity as well as pulmonary inflammation. DSCG decreased the recruitment of solely mast cells and B cells in the lung. IgE serum levels, prostaglandin D2, mucus production and IL-13 were also reduced when mice were pretreated with DSCG. S1P induced pulmonary expression of CD23 on T and B cells, that was reversed by DSCG. Conversely, S1P failed to upregulate CD23 in mast cell-deficient Kit W-sh/W-sh mice. In conclusion we have shown that DSCG inhibits S1P-induced asthma like features in the mouse. This beneficial effect is due to a regulatory action on mast cell activity, and in turn to an inhibition of IgE-dependent T and B cells responses. PMID- 27713022 TI - The underappreciated in vitro activity of tedizolid against Bacteroides fragilis species, including strains resistant to metronidazole and carbapenems. AB - Because Bacteroides fragilis has the ability to develop mechanisms of resistance to almost all antibiotics, we studied the comparative in vitro activity of tedizolid against 124 Bacteroides group species clinical isolates, including carbapenem, metronidazole and piperacillin-tazobactam resistant strains. Tedizolid had an MIC90 of 2 MUg/ml (range, 0.5-4 MUg/ml) and was 1-4 times more active than linezolid that had an MIC90 of 8 MUg/ml (range, 2-16 MUg/ml). It was also active (MICs 0.5-2 MUg/ml) against the 27 ertapenem, 2 metronidazole and 12 piperacillin-tazobactam resistant strains tested. This suggests that tedizolid may be useful treating infections, including bacteremias, due to resistant B. fragilis group species, as well as, mixed skin and soft tissue infections such as diabetic foot infections caused by Gram-positive aerobes and B. fragilis group species. PMID- 27713023 TI - Development of a screening tool to prioritize testing for the carcinogenic hazard of residual aromatic extracts and related petroleum streams. AB - Residual aromatic extracts (RAE) are petroleum substances with variable composition predominantly containing aromatic hydrocarbons with carbon numbers greater than C25. Because of the high boiling nature of RAEs, the aromatics present are high molecular weight, with most above the range of carcinogenic polycyclic aromatic hydrocarbons (PAHs). However, refinery distillations are imperfect; some PAHs and their heteroatom-containing analogs (collectively referred to as polycyclic aromatic content or PAC) may remain in the parent stream and be extracted into the RAE, and overall PAC content is related to the carcinogenic potential of an RAE. We describe here a real-time analytical chemistry-based tool to assess the carcinogenic hazard of RAE via the development of a functional relationship between carcinogenicity and boiling point. Samples representative of steps along the RAE manufacturing process were obtained from five refineries to evaluate relationships between mutagenicity index (MI), PAC ring content and gas chromatographic distillation (GCD) curves. As expected, a positive linear relationship between MI and PAC ring content occurred, most specifically for 3-6 ring PAC (R2=0.68). A negative correlation was found between MI and temperature at 5% vaporization by GCD (R2=0.72), indicating that samples with greater amounts of lower boiling constituents were more likely to be carcinogenic. The inverse relationship between boiling range and carcinogenicity was further demonstrated by fractionation of select RAE samples (MI=0.50+0.07; PAC=1.70+0.51wt%; n=5) into low and high boiling fractions, where lower boiling fractions were both more carcinogenic than the higher boiling fractions (MI=2.36+/-0.55 and 0.17+/-0.11, respectively) and enriched in 3-6 ring PACs (5.20+0.70wt% and 0.97+0.35wt%, respectively). The criteria defining carcinogenicity was established as 479 degrees C for the 5% vaporization points by GCD, with an approximate 95% probability of a future sample having an MI below the recommended limit of 0.4 for RAEs. Overall, these results provide a cost efficient and real-time tool by which the carcinogenic potential of RAEs can be assessed at the refinery level, ultimately providing a means to readily monitor and minimize the carcinogenic potential of RAEs. PMID- 27713024 TI - MicroRNA-877-5p is involved in the trovafloxacin-induced liver injury. AB - Trovafloxacin develops severe hepatotoxicity; however, the underlying mechanism of the trovafloxacin-induced liver injury has not been cleared. It has been shown that microRNAs (miRNAs) can be involved in the development of drug-induced liver injuries. We performed a miRNA microarray analysis to identify hepatic miRNAs that were induced or reduced by trovafloxacin in mice. It was demonstrated that miR-877-5p was the most increased miRNA in the mouse liver 24h after the trovafloxacin administration. To investigate the role of miR-877-5p in the liver, we established miR-877-5p-overexpressed HepG2 cells. Microarray analysis detected altered expressions in 2077 (>2-fold) and 1547 (<0.5-fold) genes in the miR-877 5p overexpressing cells compared to the mock cells. Especially, SLCO4C1, PEPCK, MT1M, HIST1H2BM, LGI1, and PLA2G2A were markedly increased or decreased in the miR-877-5p overexpressing cells. We conducted a correlation analysis between the expression levels of miR-877-5p and the six genes in eight miR-877-5p stably expressed clones. It was shown that the PEPCK expression levels were correlated with miR-877-5p expression levels. PEPCK is associated with development of apoptotic cell death; therefore, the increased miR- 877-5p-induced PEPCK can be a trigger that is involved in the development of trovafloxacin-induced liver injury. PMID- 27713025 TI - Event related potentials changes associated with the processing of auditory valid and invalid targets as a function of previous trial validity in a Posner's paradigm. AB - The present study tries to analyze the neural basis of the so-called "Inter-trial Validity-Invalidity Effects" by means of Event-Related Potentials. The N1, P2, P3a and P3b components were examined. The aim is to show the sequential effects on Event-Related Potentials by analyzing the effect of previous trial condition (n-1) in the processing of current trial target (n). Event-Related Potentials results indicate that the N1 and P2 components show higher negativity in valid trials preceded by invalid trials with respect to valid trials preceded by valid trials, elicited by the so-called "Processing Negativity". Next, the P3a and P3b components show increased positivity in invalid trials preceded by valid trials compared to invalid trials preceded by invalid trials. Present results suggest that there is a dynamic updating of attentional resources and working memory, due to the influence of previous trial condition (n-1) on the current trial processing (n). This dynamic updating would be higher after trial validity changes, and it would be compatible with the Bayesian Brain Model. PMID- 27713026 TI - Agents that activate the High Osmolarity Glycerol pathway as a means to combat pathogenic molds. AB - Treatment of invasive fungal infections often fails due to the limited number of therapeutic options. In this study, we have analyzed the impact of agents activating the High Osmolarity Glycerol (HOG) pathway on molds that cause infections in humans and livestock. We found that agents like fludioxonil and iprodione, have a clear anti-fungal activity against pathogenic Aspergillus, Lichtheimia, Rhizopus and Scedosporium species. Only A. terreus turned out to be resistant to fludioxonil, even though it is sensitive to iprodione and able to adapt to hyperosmotic conditions. Moreover, the A. terreus tcsC gene can fully complement an A. fumigatus DeltatcsC mutant, thereby also restoring its sensitivity to fludioxonil. The particular phenotype of A. terreus is therefore likely to be independent of its TcsC kinase. In a second part of this study, we further explored the impact of fludioxonil using A. fumigatus as a model organism. When applied in concentrations of 1-2MUg/ml, fludioxonil causes an immediate growth arrest and, after longer exposure, a quantitative killing. Hyphae respond to fludioxonil by the formation of new septa and closure of nearly all septal pores. Mitosis occurs in all compartments and is accompanied by a re localization of the NimA kinase to the cytoplasm. In the swollen compartments, the massive extension of the cell wall triggers a substantial reorganization resulting in an enhanced incorporation of chitin and, most strikingly, a massive loss of galactomannan. Hence, HOG-activating agents have dramatic cell biological consequences and may represent a valuable, future element in the armory that can be used to combat mold infections. PMID- 27713027 TI - The secretome of Acinetobacter baumannii ATCC 17978 type II secretion system reveals a novel plasmid encoded phospholipase that could be implicated in lung colonization. AB - Acinetobacter baumannii infections are compounded with a striking lack of treatment options. In many Gram-negative bacteria, secreted proteins play an important early role in avoiding host defences. Typically, these proteins are targeted to the external environment or into host cells using dedicated transport systems. Despite the fact that medically relevant species of Acinetobacter possess a type II secretion system (T2SS), only recently, its significance as an important pathway for delivering virulence factors has gained attention. Using in silico analysis to characterize the genetic determinants of the T2SS, which are found clustered in other organisms, in Acinetobacter species, they appear to have a unique genetic organization and are distributed throughout the genome. When compared to other T2SS orthologs, individual components of the T2SS apparatus showed the highest similarity to those of Pseudomonas aeruginosa. A mutant of Acinetobacter baumannii strain ATCC 17978 lacking the secretin component of the T2SS (DeltagspD), together with a trans-complemented mutant, were tested in a series of in vitro and in vivo assays to determine the role of T2SS in pathogenicity. The DeltagspD mutant displayed decreased lipolytic activity, associated with attenuated colonization ability in a murine pneumonia model. These phenotypes are linked to LipAN, a novel plasmid-encoded phospholipase, identified through mass spectroscopy as a T2SS substrate. Recombinant LipAN showed specific phospholipase activity in vitro. Proteomics on the T2-dependent secretome of ATCC 17978 strain revealed its potential dedication to the secretion of a number of lipolytic enzymes, among others which could contribute to its virulence. This study highlights the role of T2SS as an active contributor to the virulence of A. baumannii potentially through secretion of a newly identified phospholipase. PMID- 27713028 TI - Colistin-entrapped liposomes driven by the electrostatic interaction: Mechanism of drug loading and in vivo characterization. AB - The potential in vivo application of liposome for polycationic colistin has been hindered by the poor entrapment efficiency (EE) due to their phospholipid membrane permeability. The objective of this study is to investigate the loading mechanism and validity of applying electrostatic attraction for the colistin entrapment and delivery in liposomes. Anionic lipids with various structures were used for colistin entrapment, and the properties of resulting liposomes (i.e. zeta-potential, EE and release rate) were highly dependent on the structure of anionic lipids. Based on consideration of intermolecular interactions, the retention of electrostatically entrapped colistin is essentially determined by the balance of interfacial hydrophobic attraction and electrostatic repulsion. The liposomal colistin showed the reduced bacterial killing rate, but did not compromise the in vitro antibacterial activity. Specially, the PEGylated liposomal colistin of sodium cholesteryl sulfate (Chol-SO4-) showed the best drug retention, resulting in the significantly increased maximum-tolerated dose, prolonged blood circulation and decreased colistin distribution in kidney after intravenous administration in mice. These results highlight the potential utility of electrostatically entrapped liposome for polycationic colistin delivery. PMID- 27713029 TI - Colon targeted oral drug delivery system based on alginate-chitosan microspheres loaded with icariin in the treatment of ulcerative colitis. AB - In recent years, oral colon specific drug delivery system has been paid more attention in the treatment of inflammatory bowel disease (IBD). As the special pH condition in gastrointestinal tract, the challenge for treatment of IBD was that the colon drug delivery system should endure the low pH in stomach and release drugs quickly in high pH in colon. Icariin with the poor solubility and low bioavailability limited the treatment of many diseases in clinic. In this study, the protective mechanism of alginate-chitosan microspheres loaded with icariin were investigated with trinitrobenzene sulfonic acid (TNBS)/ethanol induced colonic mucosal injury in rats. The results of drug release showed that the icariin loaded into microspheres released only 10% in simulated gastric fluid and a high amount of 65.6% released in simulated colonic fluid. The fluorescence tracer indicated high retention of targeted microspheres more than 12h in colon. The microspheres loaded with icariin could not only reduce the colonic injury by decreasing the colon mucosa damage index in rats, but also reduce the inflammatory response by reducing the production and gene expression of inflammatory mediators and cytokines in colonic mucosa. All the results indicate that targeted microspheres loaded with icariin could exert the colon-protective effects through reducing the inflammatory response, which would be developed as a potential drug controlled release system for treatment of ulcerative colitis.

AB - Recombination-activating gene (RAG) 1 and 2 mutations in humans cause T- B- NK+ SCID and Omenn syndrome, but milder phenotypes associated with residual protein activity have been recently described. We report a male patient with a diagnosis of common variable immunodeficiency (CVID) born from non-consanguineous parents, whose immunological phenotype was characterized by severe reduction of B cells and agammaglobulinemia for which several candidate genes were excluded by targeted Sanger sequencing. Next Generation Sequencing revealed two compound heterozygous mutations in the RAG1 gene: the previously described p.R624H, and the novel p.Y728H mutation, as well as the known polymorphism p.H249R. This case reinforces the notion of large phenotypic spectrum in RAG deficiency and opens questions on the management and follow-up of these patients.

PMID- 27713030 TI - Role of the JAK/STAT signaling pathway in regulation of innate immunity in neuroinflammatory diseases. AB - The Janus Kinase/Signal Transducers and Activators of Transcription (JAK/STAT) signaling pathway is utilized by numerous cytokines and interferons, and is essential for the development and function of both innate and adaptive immunity. Aberrant activation of the JAK/STAT pathway is evident in neuroinflammatory diseases such as Multiple Sclerosis and Parkinson's Disease. Innate immunity is the front line defender of the immune system and is composed of various cell types, including microglia, macrophages and neutrophils. Innate immune responses have both pathogenic and protective roles in neuroinflammation, depending on disease context and the microenvironment in the central nervous system. In this review, we discuss the role of innate immunity in the pathogenesis of neuroinflammatory diseases, how the JAK/STAT signaling pathway regulates the innate immune response, and finally, the potential for ameliorating neuroinflammation by utilization of JAK/STAT inhibitors. PMID- 27713033 TI - A 10-Year Longitudinal Study of Effects of a Multifaceted Residency Spiritual Care Curriculum: Clinical Ability, Professional Formation, End of Life, and Culture. AB - CONTEXT: Although spiritual care (SC) is recognized as important in whole-person medicine, physicians infrequently address patients' spiritual needs, citing lack of training. Although many SC curricula descriptions exist, few studies report effects on physicians. OBJECTIVES: To broadly examine immediate and long-term effects of a required, longitudinal, residency SC curriculum, which emphasized inclusive patient-centered SC, compassion, and spiritual self-care. METHODS: We conducted in-depth individual interviews with 26 physicians (13 intervention; 13 comparison) trained at a 13-13-13 residency. We interviewed intervention physicians three times over 10 years-1) preintervention, as PGY1s, 2) postintervention, as PGY3s, 3) eight-year postintervention, as practicing physicians. We interviewed comparison physicians as PGY3s. Interviews were audio recorded, transcribed, and analyzed by four researchers. RESULTS: Forty-nine interviews were analyzed. General: Both groups were diverse regarding personal importance of spirituality/religion. All physicians endorsed the value of SC, sharing rich patient stories particularly related to end of life and cultural diversity. Curricular effects: 1) skills/barriers-intervention physicians demonstrated progressive improvements in clinical approach, accompanied by diminishing worries related to SC. PGY3 comparison physicians struggled with SC skills and worries more than PGY3 intervention physicians, 2) physician formation most physicians described residency as profoundly challenging and transformative. Even after eight years, many intervention physicians noted that reflection on their diverse beliefs and values in safety, coupled with compassion shown to them through this curriculum, had deeply positive effects. High impact training: patient-centered spiritual assessment; chaplain rounds; spiritual self-care workshop/retreats; multicultural SC framework. CONCLUSION: A longitudinal, multifaceted residency SC curriculum can have lasting positive effects on physicians' SC skills and their professional/personal formation.

AB - The in vivo fate of lipid-based nanoparticles (LBNs) is essentially determined by the properties of their lipid compositions. LBNs are rapidly degraded via lipolysis wherever lipases are abundant, especially in the gastrointestinal tract. LBNs that survive lipolysis can be translocated through the circulation to reach terminal organs or tissues. Lipid composition, particle size, and surface decoration, as well as the formation of protein corona, are the main factors influencing the in vivo fate of LBNs. As we discuss here, elucidation of the in vivo fate of LBNs helps weigh the balance between lipolysis and biorecognition, and is emerging as a new field of research. PMID- 27713036 TI - Insulin resistance and Parkinson's disease: A new target for disease modification? AB - There is growing evidence that patients with Type 2 diabetes have an increased risk of developing Parkinson's disease and share similar dysregulated pathways suggesting common underlying pathological mechanisms. Historically insulin was thought solely to be a peripherally acting hormone responsible for glucose homeostasis and energy metabolism. However accumulating evidence indicates insulin can cross the blood-brain-barrier and influence a multitude of processes in the brain including regulating neuronal survival and growth, dopaminergic transmission, maintenance of synapses and pathways involved in cognition. In conjunction, there is growing evidence that a process analogous to peripheral insulin resistance occurs in the brains of Parkinson's disease patients, even in those without diabetes. This raises the possibility that defective insulin signalling pathways may contribute to the development of the pathological features of Parkinson's disease, and thereby suggests that the insulin signalling pathway may potentially be a novel target for disease modification. Given these growing links between PD and Type 2 diabetes it is perhaps not unsurprising that drugs used the treatment of T2DM are amongst the most promising treatments currently being prioritised for repositioning as possible novel treatments for PD and several clinical trials are under way. In this review, we will examine the underlying cellular links between insulin resistance and the pathogenesis of PD and then we will assess current and future pharmacological strategies being developed to restore neuronal insulin signalling as a potential strategy for slowing neurodegeneration in Parkinson's disease.

AB - High-throughput sequencing analysis has accelerated searches for genes associated with risk for colorectal cancer (CRC); germline mutations in NTHL1, RPS20, FANCM, FAN1, TP53, BUB1, BUB3, LRP6, and PTPN12 have been recently proposed to increase CRC risk. We attempted to validate the association between variants in these genes and development of CRC in a systematic review of 11 publications, using sequence data from 863 familial CRC cases and 1604 individuals without CRC (controls). All cases were diagnosed at an age of 55 years or younger and did not carry mutations in an established CRC predisposition gene. We found sufficient evidence for NTHL1 to be considered a CRC predisposition gene-members of 3 unrelated Dutch families were homozygous for inactivating p.Gln90Ter mutations; a Canadian woman with polyposis, CRC, and multiple tumors was reported to be heterozygous for the inactivating NTHL1 p.Gln90Ter/c.709+1G>A mutations; and a man with polyposis was reported to carry p.Gln90Ter/p.Gln287Ter; whereas no inactivating homozygous or compound heterozygous mutations were detected in controls. Variants that disrupted RPS20 were detected in a Finnish family with early-onset CRC (p.Val50SerfsTer23), a 39-year old individual with metachronous CRC (p.Leu61GlufsTer11 mutation), and a 41-year-old individual with CRC (missense p.Val54Leu), but not in controls. We therefore found published evidence to support the association between variants in NTHL1 and RPS20 with CRC, but not of other recently reported CRC susceptibility variants. We urge the research community to adopt rigorous statistical and biological approaches coupled with independent replication before making claims of pathogenicity. PMID- 27713041 TI - Reply.

Iron overload was induced in male ICR mice by injection of iron sucrose (10mg/kg/day) for eight weeks. Iron overload was evidenced by increased serum iron indices. The mice developed increased blood pressure, impaired vascular function and blunted response of the autonomic nervous system. These effects were accompanied by increased malondialdehyde levels in various tissues, increased nitric oxide metabolites in plasma and urine, and decreased blood glutathione. Tetrahydrocurcumin (THU, 50mg/kg/day), deferiprone (or L1, 50mg/kg/day) or both was orally administered throughout the period of iron sucrose injection. The treatments significantly alleviated the deleterious cardiovascular effects of iron overload, and were associated with modulation of nitric oxide levels. An imbalance between endothelial nitric oxide synthase (eNOS) and inducible NOS (iNOS) expression in response to iron overload was normalized by THU, L1 or the combination treatment. Moreover, the treatment decreased the upregulated expression levels of gp91phox, p47phox and HO-1. The combination of THU and L1 exerted a greater effect than THU or L1 monotherapy. These results suggest beneficial effects of THU and L1 on iron-induced oxidative stress, hypertension, and vascular dysfunction. PMID- 27713042 TI - An Uncommon Cause of Gas Gangrene.

AB - OBJECTIVE: Since reconstruction of composite defects in the head and neck region is a challenging and demanding problem for head and neck surgeons, surgical aids have been sought for decades. The purpose of this study was to evaluate the accuracy of prefabricated surgical resection templates used in mandibular segmental resections in comparison to the virtual surgical plan. MATERIALS AND METHODS: A prospective study was performed in 11 consecutive patients, with a primary T4 oral squamous cell carcinoma or osteoradionecrosis of the mandible. Preoperatively, a CBCT scan was acquired to delineate the size and extension of tumor invasion; a virtual patient-specific resection template was designed based on this information. Intraoperatively, the resection template was positioned on the mandible and secured using four fixation screws. Postoperatively, a CBCT scan was acquired. This scan was superimposed on the preoperative scan. Positioning of the resection template and inclination of the resection planes were evaluated on the virtual head model. In order to test the interobserver reliability of these new measurement methods, two different observers executed all measurements. RESULTS: The mean shift of the proximal resection templates was 3.76 mm (standard deviation [SD] 3.10 mm). For the distal resection templates, the mean shift was 3.06 mm (SD 1.57 mm) with no significant interobserver difference (ICC = 0.99). An absolute mean deviation of 8.5 degrees (SD 5.3 degrees ) was found for the proximal resection angle and 10.4 degrees (SD 5.0 degrees ) for the distal resection angle. Again, no significant interobserver differences were found (ICC = 0.98). CONCLUSION: The resection templates used in this study proved reasonably accurate. Although the concept of virtual surgical planning aids significantly in mandibular reconstruction with microvascular free flaps, further improvement of resection accuracy is necessary for further improvement of reconstruction accuracy. PMID- 27713053 TI - Development of a virtual reality training system for endoscope-assisted submandibular gland removal. AB - PURPOSE: Endoscope-assisted surgery has widely been adopted as a basic surgical procedure, with various training systems using virtual reality developed for this procedure. In the present study, a basic training system comprising virtual reality for the removal of submandibular glands under endoscope assistance was developed. The efficacy of the training system was verified in novice oral surgeons. MATERIAL AND METHODS: A virtual reality training system was developed using existing haptic devices. Virtual reality models were constructed from computed tomography data to ensure anatomical accuracy. Novice oral surgeons were trained using the developed virtual reality training system. RESULTS: The developed virtual reality training system included models of the submandibular gland and surrounding connective tissues and blood vessels entering the submandibular gland. Cutting or abrasion of the connective tissue and manipulations, such as elevation of blood vessels, were reproduced by the virtual reality system. A training program using the developed system was devised. Novice oral surgeons were trained in accordance with the devised training program. CONCLUSIONS: Our virtual reality training system for endoscope-assisted removal of the submandibular gland is effective in the training of novice oral surgeons in endoscope-assisted surgery. PMID- 27713054 TI - Improving the accuracy of mandibular reconstruction with vascularized iliac crest flap: Role of computer-assisted techniques. AB - While vascularized iliac crest flap is widely used for mandibular reconstruction, it is often challenging to predict the clinical outcome in a conventional operation based solely on the surgeon's experience. Herein, we aimed to improve this procedure by using computer-assisted techniques. We retrospectively reviewed records of 45 patients with mandibular tumor who underwent mandibulectomy and reconstruction with vascularized iliac crest flap from January 2008 to June 2015. Computer-assisted techniques including virtual plan, stereomodel, pre-bending individual reconstruction plate, and surgical navigation were used in 15 patients. The other 30 patients underwent conventional surgery based on the surgeon's experience. Condyle position and reconstructed mandible contour were evaluated based on post-operative computed tomography. Complications were also evaluated during the follow-up. Flap success rate of the patients was 95.6% (43/45). Those in the computer-assisted group presented with better outcomes of the mandibular contour (p = 0.001) and condyle position (p = 0.026). Further, they also experienced beneficial dental restoration (p = 0.011) and postoperative appearance (p = 0.028). The difference between postoperative effect and virtual plan was within the acceptable error margin. There is no significant difference in the incidence of post-operative complications. Thus, computer-assisted techniques can improve the clinical outcomes of mandibular reconstruction with vascularized iliac crest flap.

AB - The genotype V has been the most prevalent dengue virus type 1 (DENV-1) clade circulating in the Americas over the last 40years. In this study, we investigate the spatiotemporal pattern of emergence and dissemination of DENV-1 lineages in the continent. We applied phylogenetic and phylogeographic approaches to a comprehensive data set of 836 DENV-1 E gene sequences of the genotype V isolated from 46 different countries around the world over a period of 50years (1962 to 2014). Our study reveals that genetic diversity of DENV-1 genotype V in the Americas resulted from two independent introductions of this genotype from India. The first genotype V strain was most probably introduced into the Lesser Antilles at around the early 1970s and this Caribbean region becomes the source population of several DENV-1 lineages that spread in the Americas during the 1970s and 1980s. Most of those lineages appear to become extinct during the 1990s, except one that persisted in Venezuela and later spread to other American countries, dominating the DENV-1 epidemics in the region from the early 2000s onwards. The second genotype V strain of Indian origin was also most probably introduced into the Lesser Antilles at around the early 1980s. This lineage remained almost undetected for nearly 15years, until it was introduced in Northern Brazil around the middle 1990s and later spread to other country regions. These results demonstrate that different geographic regions have played a role in maintaining and spreading the DENV-1 genotype V in the Americas over time. DENV-1 genotype V lineages have originated, spread and died out in the Americas with very different dynamics and the phenomenon of lineage replacement across successive DENV-1 epidemic outbreaks was a common characteristic in most American countries. PMID- 27713056 TI - Cross-Disciplinary Analysis of Lymph Node Classification in Lung Cancer on CT Scanning. AB - BACKGROUND: Accurate and consistent regional lymph node classification is an important element in the staging and multidisciplinary management of lung cancer. Regional lymph node definition sets-lymph node maps-have been created to standardize regional lymph node classification. In 2009, the International Association for the Study of Lung Cancer (IASLC) introduced a lymph node map to supersede all preexisting lymph node maps. Our aim was to study if and how lung cancer specialists apply the IASLC lymph node map when classifying thoracic lymph nodes encountered on CT scans during lung cancer staging. METHODS: From April 2013 through July 2013, invitations were distributed to all members of the Fleischner Society, Society of Thoracic Radiology, General Thoracic Surgical Club, and the American Association of Bronchology and Interventional Pulmonology to participate in an anonymous online image-based and text-based 20-question survey regarding lymph node classification for lung cancer staging on CT imaging. RESULTS: Three hundred thirty-seven people responded (approximately 25% participation). Respondents consisted of self-reported thoracic radiologists (n = 158), thoracic surgeons (n = 102), and pulmonologists who perform endobronchial ultrasonography (n = 77). Half of the respondents (50%; 95% CI, 44%-55%) reported using the IASLC lymph node map in daily practice, with no significant differences between subspecialties. A disparity was observed between the IASLC definition sets and their interpretation and application on CT scans, in particular for lymph nodes near the thoracic inlet, anterior to the trachea, anterior to the tracheal bifurcation, near the ligamentum arteriosum, between the bronchus intermedius and esophagus, in the internal mammary space, and adjacent to the heart. CONCLUSIONS: Use of older lymph node maps and inconsistencies in interpretation and application of definitions in the IASLC lymph node map may potentially lead to misclassification of stage and suboptimal management of lung cancer in some patients. PMID- 27713057 TI - Signalling pathways in trophic skeletal development and morphogenesis: Insights from studies on teleost fish. AB - During the development of the vertebrate feeding apparatus, a variety of complicated cellular and molecular processes participate in the formation and integration of individual skeletal elements. The molecular mechanisms regulating the formation of skeletal primordia and their development into specific morphological structures are tightly controlled by a set of interconnected signalling pathways. Some of these pathways, such as Bmp, Hedgehog, Notch and Wnt, are long known for their pivotal roles in craniofacial skeletogenesis. Studies addressing the functional details of their components and downstream targets, the mechanisms of their interactions with other signals as well as their potential roles in adaptive morphological divergence, are currently attracting considerable attention. An increasing number of signalling pathways that had previously been described in different biological contexts have been shown to be important in the regulation of jaw skeletal development and morphogenesis. In this review, I provide an overview of signalling pathways involved in trophic skeletogenesis emphasizing studies of the most species-rich group of vertebrates, the teleost fish, which through their evolutionary history have undergone repeated episodes of spectacular trophic diversification. PMID- 27713058 TI - Organogenesis of adult lung in a dish: Differentiation, disease and therapy. AB - The remarkable regenerative capacity of the lung suggests that stem cells could be of therapeutic importance in diverse lung diseases; however, the successful exploitation of lung stem cell biology has long been hampered by our inability to maintain and expand adult lung stem cells while retaining their multi-lineage potential in vitro. Recently, advances in our understanding of stem cell niches and the role of key signalling modulators in controlling stem cell maintenance and differentiation have fuelled the development of new in vitro three dimensional (3D) culture technologies that sustain the stem cell-driven formation of near-physiological, self-organizing structures called organoids. Here we review basic approaches to organoid model systems and highlight recent achievements in the generation of organoids from adult stem and progenitor cells of both the murine and human lungs. We evaluate current applications in studying cellular changes in proliferation, differentiation, plasticity, and cell polarity, and cellular and molecular crosstalk of epithelial cells with stroma. Advantages and limitations of organoids for clinical use are also discussed. PMID- 27713060 TI - Affinity purification of native glycodelin from amniotic fluid for biological investigations and development of a glycodelin ELISA for clinical studies. AB - INTRODUCTION: Glycodelin is a glycoprotein with different oligosaccharides that are responsible for its diverse biological functions in contraception and immunosuppression. Therefore, it is necessary to have access to adequate amounts of glycodelin with retained carbohydrate structure for functional studies because the carbohydrate part can be lacking or be insufficient in recombinant glycodelin from prokaryotic and eukaryotic cell systems. METHODS AND RESULTS: Native glycodelin was purified from amniotic fluid by a series of affinity chromatography steps and had many glycosylated forms verified by mass spectrometry. About 7.5 mg glycodelin was obtained from 1.5 L amniotic fluid. No high molecular mass forms of glycodelin were found in amniotic fluid. Aliquots of the purified glycodelin were used as an immunogen in rabbits for antibody production against glycodelin and a calibrator in a highly sensitive glycodelin enzyme-linked immunosorbent assay (ELISA) with a detection limit of about 1 MUg/L. CONCLUSIONS: Native glycodelin was purified from amniotic fluid and used as an immunogen for raising a rabbit antibody against glycodelin and a calibrator in a highly sensitive glycodelin ELISA. We found no high molecular mass forms of glycodelin in amniotic fluid. Aliquots of the purified glycodelin were set aside for functional studies which are in progress. PMID- 27713059 TI - Bmp4-Msx1 signaling and Osr2 control tooth organogenesis through antagonistic regulation of secreted Wnt antagonists. AB - Mutations in MSX1 cause craniofacial developmental defects, including tooth agenesis, in humans and mice. Previous studies suggest that Msx1 activates Bmp4 expression in the developing tooth mesenchyme to drive early tooth organogenesis. Whereas Msx1-/- mice exhibit developmental arrest of all tooth germs at the bud stage, mice with neural crest-specific inactivation of Bmp4 (Bmp4ncko/ncko), which lack Bmp4 expression in the developing tooth mesenchyme, showed developmental arrest of only mandibular molars. We recently demonstrated that deletion of Osr2, which encodes a zinc finger transcription factor expressed in a lingual-to-buccal gradient in the developing tooth bud mesenchyme, rescued molar tooth morphogenesis in both Msx1-/- and Bmp4ncko/ncko mice. In this study, through RNA-seq analyses of the developing tooth mesenchyme in mutant and wildtype embryos, we found that Msx1 and Osr2 have opposite effects on expression of several secreted Wnt antagonists in the tooth bud mesenchyme. Remarkably, both Dkk2 and Sfrp2 exhibit Osr2-dependent preferential expression on the lingual side of the tooth bud mesenchyme and expression of both genes was up-regulated and expanded into the tooth bud mesenchyme in Msx1-/- and Bmp4ncko/ncko mutant embryos. We show that pharmacological activation of canonical Wnt signaling by either lithium chloride (LiCl) treatment or by inhibition of DKKs in utero was sufficient to rescue mandibular molar tooth morphogenesis in Bmp4ncko/ncko mice. Furthermore, whereas inhibition of DKKs or inactivation of Sfrp2 alone was insufficient to rescue tooth morphogenesis in Msx1-/- mice, pharmacological inhibition of DKKs in combination with genetic inactivation of Sfrp2 and Sfrp3 rescued maxillary molar morphogenesis in Msx1-/- mice. Together, these data reveal a novel mechanism that the Bmp4-Msx1 pathway and Osr2 control tooth organogenesis through antagonistic regulation of expression of secreted Wnt antagonists. PMID- 27713061 TI - The Total Calvarial Transsutural Distraction Osteogenesis for 26 Children with Slit Ventricle, Craniosynostosis, or Microcephaly After Shunt Operation. AB - OBJECTIVE: Among shunt complications, the postshunt slit ventricle (PSSV) and the postshunt craniosynostosis (PSCS) may be managed by shunt valve upgrade and/or cranial expansion surgery. Here, we analyzed 26 children with PSSV, PSCS, or microcephaly who received simple generalized cranial expansion (ie, total calvarial transsutural distraction osteogenesis [TC-TSuDO]). METHODS: Among 254 children with shunt surgery, 26 children received TC-TSuDO. These 26 children included 14 with PSSV, 4 with PSCS, and 8 with both PSSV and PSCS. The mean age of patients who underwent shunt procedures was 8.2 +/- 10.6 months, and the mean time interval from shunt surgery to TC-TSuDO was 26.8 +/- 29.5 months. The mean age of children at the time of TC-TSuDO was 33.3 +/- 30.2 months. We analyzed head circumferences, lumbar puncture pressures, development status, operative factors, and postoperative complications. RESULTS: The mean preoperative head circumference was -2.1 +/- 1.9, which increased to -1.4 +/- 2.1 (P < 0.001) postsurgically. The mean preoperative lumbar puncture pressure was 26.2 +/- 10.7 cm H2O which decreased to 11.9 +/- 3.5 cm H2O (P < 0.001) after surgery. The mean operation time was 138 +/- 66 minutes. The mean intensive care unit stay was 0.27 +/- 0.53 days. There were no mortalities but 2 patients suffered from distractor malfunction and 1 patient showed wound discharge. CONCLUSIONS: We suggest that postshunt complications such as PSSV or PSCS, especially those that are accompanied by increased intracranial pressure or postshunt microcephaly, may be managed for patients with TC-TSuDO, which has been shown to be safe, simple, and effective. PMID- 27713062 TI - Intradural Carcinoid Tumor Found in a Patient with No History of Cancer. AB - BACKGROUND: Carcinoid tumors are rare neoplasms that often arise from the gastrointestinal or respiratory tracts. They often metastasize to bone tissue and pancreatic and hepatic sites. The central nervous system and most specifically the spinal cord are rarely involved. Primary carcinoid tumors of the central nervous system are even rarer. CASE DESCRIPTION: A 58-year-old man presented with progressive bilateral lower extremity weakness and a negative history of cancer. Imaging revealed an intradural mass at the L1 and L2 spinal levels. Surgical resection of the tumor via laminectomy was performed. The tumor was observed to have eroded through the dura and was compressing the spinal nerves. Histopathologically, the mass was observed to be of carcinoid origin. A subsequent octreoscan revealed no primary sites of carcinoid tumor. Postoperatively, the patient was followed for 1.5 years. The patient reported improvement in sensation to his lower extremities with no change in motor findings. CONCLUSIONS: Carcinoid tumors of the central nervous system are extremely rare, but they should remain in the differential diagnosis for patients experiencing extremity weakness and back or neck pain with an intradural mass and no primary source of the tumor identified or other manifestations of a primary tumor. PMID- 27713063 TI - Radiation-Induced Meningiomas: An Exhaustive Review of the Literature. AB - OBJECTIVE: Radiation-induced meningioma (RIM) is an uncommon late risk of cranial irradiation. We conducted an exhaustive review of individual patient data to characterize RIM. METHODS: Using a systematic search of the PubMed database, we performed a comprehensive literature review to characterize and investigate RIM. Student t tests were used to evaluate differences between variables. A Kaplan Meier analysis was used to assess survival. Statistical significance was assessed using a log-rank test. RESULTS: Our analysis included 251 cases of RIM. The average age at onset for the primary lesion was 13.0 +/- 13.5 years, and the average radiation dose delivered to this lesion was 38.8 +/- 16.8 Gy. Secondary meningiomas could be divided into grades I (140), II (55), and III (10) tumors. Thirty patients (11.9%) had multiple lesions, and 46 (18.3%) had recurrent meningiomas. The latency period between radiotherapy for primary lesions and the onset of meningiomas was 22.9 +/- 11.4 years. The latency period was shorter for patients with grade III meningioma and for those in the high-dose and intermediate-dose radiation groups who received systemic chemotherapy. Aggressive meningiomas and multiple meningiomas were more common in the high-dose and intermediate-dose groups than in the low-dose group. The 5-year and 10-year survival rates for all patients with meningioma were 77.7% and 66.1%, respectively. CONCLUSIONS: For patients treated with cranial radiotherapy, the risk of secondary meningioma warrants a longer follow-up period beyond the standard time frame typically designated for determining the risk of primary tumor relapse. PMID- 27713064 TI - Aggressive Pituitary Adenomas: The Dark Side of the Moon. AB - BACKGROUND: Although pituitary adenomas are considered benign lesions, a small group may show clinically aggressive behavior, sometimes independently from the classic markers of aggressiveness, including the Ki67 labeling index or p53 expression. METHODS: We selected 7 patients harboring a pituitary tumor with clinical features of aggressiveness. Patients underwent a full preoperative and postoperative endocrinologic and neuroradiologic workup. Two were nonfunctioning, 2 prolactin-secreting, 2 adrenocorticotrophic hormone-secreting, and 1 a growth hormone-secreting adenoma. RESULTS: The 7 patients underwent a total of 17 surgical procedures. At the first surgical procedure, gross total removal was achieved in none of the patients, whereas subtotal removal (>90% of tumor removed) was achieved in 4/7 cases and partial removal (<90% of tumor removed) in 3/7 cases. At first operation, 4/7 patients showed a Ki67 index <=3% and 2/7 >3%; this information was not available for 1 patient. Postoperatively, all patients underwent radiation therapy. Three patients received chemotherapy with temozolomide. Three patients underwent peptide receptor radionuclide therapy. To date, 1 patient has died of tumor progression, and 2 patients are in a poor general condition. The remaining 4 patients are in a fair/good condition, without any major complaints. The mean follow-up is 43.42 months. CONCLUSIONS: Aggressive pituitary adenomas represent a specific and still underestimated entity, often diagnosed late. Clinical and neuroradiologic rapid progression is often the only marker of aggressiveness. Surgical debulking remains the first therapeutic option. Multidisciplinary management is mandatory to offer these patients targeted therapeutic options. PMID- 27713065 TI - Using Intraoperative Ultrasonography for Spinal Cord Tumor Surgery. AB - BACKGROUND: Our aim was to evaluate the usefulness of modern intraoperative ultrasonography (iUS) in the resection of a wide variety of spinal intradural pathologic entities. METHODS: We evaluated patients with spinal cord disease treated between January 2006 and September 2015. Intraoperative standard B-mode images were acquired using a 3.5-MHz to 12-MHz ultrasonographic probes (linear and curvilinear) on various ultrasound machines. The benefits and disadvantages of iUS were assessed for each case. RESULTS: A total number of 158 intradural spinal lesions were operated on using iUS. Of these, 107 lesions (68%) were intradural extramedullary and 51 (32%) were intramedullary. All lesions were clearly visible using the ultrasound probe. The high-frequency linear probes (10 12 MHz) provided a better image quality compared with lower-frequency probes. Color and power-angiography modes were helpful in assessing the vascularization of the tumors and location of the major vessels in the vascular lesions. DISCUSSION: We document how iUS was used to facilitate safe and efficient spinal tumor resection at each stage of the operation. iUS was beneficial in confirmation of tumor location and extension, planning myelotomy, and estimation of degree of resection of the intramedullary tumors. It was particularly helpful in guiding the approach in redo surgeries for recurrent spinal cord tumors. CONCLUSIONS: iUS has a fast learning curve and offers additional intraoperative information that can help improve surgical accuracy and therefore may reduce procedure-related morbidity. PMID- 27713066 TI - Impact of Age on Change in Self-Image 5 Years After Complex Spinal Fusion (>=5 Levels). AB - BACKGROUND: Spinal deformities that require >=5 fusion levels are difficult and challenging for both the surgeon and patient. Corrections of moderate to severe deformities have been shown to improve patient-reported outcomes (PROs), and provide patients with a better quality of life. Self-image is an important PRO because it sheds insight into the patient's perception of health, as well as serving as a proxy of satisfaction for patients with spine deformity undergoing corrective surgery. However, with an aging population, the impact of age on long term change in self-image is unknown. The aim of this study is to determine the effects of age on self-image 5 years after undergoing an elective complex spinal fusion (>=5 levels). METHODS: This was a retrospective analysis of prospectively collected data of 55 adult patients (>=18 years old) undergoing >=5 levels of spinal fusion to the sacrum with iliac fixation from January 2002 to December 2008. Patients were grouped by age: young (<60 years old) and older (>=60 years old). Patient demographics, comorbidities, preoperative variables (sagittal and Cobb angles) and postoperative complication rates were collected. All patients had prospectively collected outcome measures and a minimum of 5 years follow-up. PRO instrument SRS-22r (function, self-image, mental health, and pain) was completed before surgery then at follow-up (at least 5 years after surgery). The primary outcome investigated in this study was the change in self-image after surgery. RESULTS: Baseline characteristics and preoperative variables were similar in both cohorts. There were no significant differences in intraoperative variables, including the mean +/- standard deviation number of fusion levels between the cohorts (young, 11.2 +/-4.3 vs. older, 12.1 +/- 4.0; P = 0.42). Complication rates were similar between the cohorts, with no significant differences in the types of complications (young, 29.63% vs. older, 25.0%; P = 0.77). There were no significant differences in preoperative and follow-up PROs between the cohorts. The mean +/- standard deviation preoperative and follow-up self-image scores were (young, 2.35+/-0.58 vs. older, 2.68 +/- 0.64; P = 0.51) and (young, 3.82 +/- 0.63 vs. older, 3.51 +/- 0.94), respectively. There were no significant differences in the change of function, mental health, or pain between the cohorts. However, the younger cohort experienced a significantly greater overall change in self-image than did the older cohort (young, 1.49 +/- 0.87 vs. older, 0.70+/-1.14; P = 0.01). CONCLUSIONS: Our study suggests that age significantly affects the perception of self-image after deformity correction surgery; with younger patients reporting a greater change from baseline in self image after surgery. Further studies are necessary to corroborate our observed findings. PMID- 27713067 TI - Clinical Experience with Intraoperative Ultrasonographic Image in Microsurgical Resection of Cerebral Arteriovenous Malformations. AB - BACKGROUND: Intraoperative ultrasonography is widely used in neurosurgery for the management of intracerebral hematoma and brain tumor. However, the clinical value of this method in the surgery of cerebral arteriovenous malformations (AVMs) has not been reported. In this study, the application of intraoperative ultrasonography for AVM surgery was evaluated prospectively. METHODS: This prospective clinical study comprised 41 patients who underwent microsurgical resection of cerebral AVMs at our institute. After routine craniotomy, ultrasonographic imaging with color Doppler ultrasonography and real-time contrast-enhanced ultrasonographic angiography if necessary were applied as navigated images on the monitor during the operation. RESULTS: Ultrasonographic imaging made it easier to understand the vascular architecture during the operation. Color Doppler flow imaging clearly delineated the shape and margin of the AVMs. Intraoperative real-time contrast-enhanced ultrasonographic angiography enabled the surgeons to categorically identify AVM feeders both on the surface and deep in the tissue. CONCLUSIONS: Microneurosurgery with intraoperative ultrasonographic image guidance was a safe, effective, and reliable method for identifying the afferent and efferent vessels and for confirming the complete resection of AVMs. These benefits of image-guided microsurgery were mostly apparent for deep-seated AVMs that were not visible on the surface of the brain. PMID- 27713068 TI - Cloning and expression study of a Toll-like receptor 2 (tlr2) gene from turbot, Scophthalmus maximus. AB - Toll-like receptor 2 (TLR2) in mammals is a member of the ancient Toll-like family of receptors that predominantly recognizes conserved components of Gram positive bacteria. In the present study, a tlr2 gene and its 5'-flanking sequence were cloned from turbot, Scophthalmus maximus, its responsive expressions to various immunostimulants were subsequently studied in vivo. The turbot (sm)tlr2 gene spans over 9.0 kb with a structure of 12 exon-11 intron and encodes 816 amino acids. The deduced protein shows the highest sequence identity (76.1%) to Japanese flounder Tlr2 and possesses a signal peptide sequence, a leucine-rich repeat (LRR) domain composed of 19 LRR motifs, a transmembrane region and a Toll/interleukin-1 receptor (TIR) domain. Phylogenetic analysis grouped it with other neoteleostei Tlr2as. A number of transcription factor binding sites known to be important for the basal transcriptional activity of TLR3 and response of TLR2 to lipopolysaccharide (LPS) signalling in mammals were predicted in the 5' flanking sequence of smtlr2. Quantitative real-time PCR (qPCR) analysis demonstrated the constitutive expression of smtlr2 mRNA in all twelve examined tissues with higher levels in the lymphomyeloid-rich tissues and liver. Further, smtlr2 expression was up-regulated following stimulation with LPS, peptidoglycan (PGN) or polyinosinic: polycytidylic acid [poly(I:C)] in the gills, head kidney, spleen and muscle. Finally, for all three immunostimulants, a two-wave induced smtlr2 expression was observed in the head kidney and spleen in a 7-day time course and the strongest inducibility in the head kidney. These findings suggest a possible role of Smtlr2 in the immune responses to the infections of a broad range of pathogens that include Gram-positive and Gram-negative bacteria and RNA virus. PMID- 27713069 TI - A Neurophysiological examination of quality of learning in a feedback-based learning task. AB - The efficiency with which one processes external feedback contributes to the speed and quality of one's learning. Previous findings that the feedback related negativity (FRN) event related potential (ERP) is modulated by learning outcomes suggested that this ERP reflects the extent to which feedback is used by the learner to improve performance. To further test this suggestion, we measured whether the FRN and the fronto-central positivity (FCP) that follows it are modulated by learning slopes, and as a function of individual differences in learning outcomes. Participants were tasked with learning names (non-words) of 42 novel objects in a two-choice feedback-based visual learning task. The items were divided into three sets of 14 items, each presented in five learning blocks and a sixth test block. Individual learning slopes based on performance on the task, as well as FRN and FCP slopes based on positive and negative feedback related activation in each block were created for 53 participants. Our data pointed to an interaction between slopes of the FRN elicited by negative feedback and learning slopes, such that a sharper decrease in the amplitude of the FRN to negative feedback was associated with sharper learning slopes. We further examined the predictive power of the FRN and FCP elicited in the training blocks on the learning outcomes as measured by performance on the test blocks. We found that small FRN to negative feedback, large FRN to positive feedback, and large FCP to negative feedback in the first training block predicted better learning outcomes. These results add to the growing evidence that the processes giving rise to the FRN and FCP are sensitive to individual differences in the extent to which feedback is used for learning. PMID- 27713070 TI - Renal Parenchyma to Hydronephrosis Area Ratio (PHAR) as a Predictor of Future Surgical Intervention for Infants With High-grade Prenatal Hydronephrosis. AB - OBJECTIVE: To explore the potential value of an objective assessment, renal parenchyma to hydronephrosis area ratio (PHAR), as an early predictor of surgery. METHODS: Initial sagittal renal ultrasound (US) images of patients prospectively entered into a prenatal hydronephrosis database from January 2008 to January 2016 with baseline Society for Fetal Urology (SFU) grades III and IV prenatal hydronephrosis, without vesicoureteral reflux, were evaluated using the National Institutes of Health-sponsored image processing software. PHAR, anteroposterior diameter, SFU grade, and urinary tract dilation risk categories were contrasted with nuclear scan data (differential renal function and drainage time [t1/2]) and analyzed for predictive value in determining the decision to proceed with surgery by drawing receiver operating characteristic curves. RESULTS: Out of 196 infants (162 male; 138 left sided hydronephrosis), 58 (30%) underwent surgery to address obstruction. Surgical patients compared with those managed conservatively had longer t1/2 (60 vs 18 min; P < .01) and lower differential renal function (46 vs 50%; P = .01). Of the initial US parameters, PHAR (area under the curve = 0.816; P < .001) had a better predictive performance than anteroposterior diameter, SFU grade, or urinary tract dilation classification. PHAR values correlated with subsequent parameters obtained on nuclear scan. CONCLUSION: PHAR is a promising parameter that can be estimated on presentation US to help predict future need for surgery in newborns with high-grade hydronephrosis.

AB - OBJECTIVE: The objective of this study is to describe the current situation regarding the training, working conditions, future plans, fields of interest and satisfaction of orthopaedics and traumatology residents in Turkey. METHODS: A descriptive survey questionnaire consisting of 24 questions was designed to identify the problems and solution suggestions concerning training of orthopaedic residents. All orthopaedics and traumatology residents who took the 2013 Progress Testing for Speciality in Medicine (UEGS) held by Turkish Orthopaedics and Traumatology Education Council (TOTEK) were surveyed in the class at the end thereof as well as the young orthopaedic surgeons who were reached through the email groups of Turkish Society of Orthopaedics and Traumatology - Residents and Young Attendings Council (TOTBID-AGUH). RESULTS: A total of 725 residents and 132 young attendings were surveyed. The most outstanding answers are as follows: 62,7% of the respondents replied to the question "Is there a training program/Is it being applied" as "yes/yes". It was found out that 94,3% of the respondents wanted to be involved in a rotation abroad. The "patient care" was the most common answer, with a ratio of 36,9%, to the question "What's the priority of the department you are studying in?". Regarding work conditions, "many emergency on calls" was found to be the most important parameter affecting life conditions (p < 0.05). CONCLUSION: Aiming to identify the challenges that orthopaedics and traumatology residents in Turkey face as regards their training, this survey stands as a pioneering study with a high participation rate. Analysis of survey data highlights the importance of several key factors such as the development of training programs and increasing the time spent with academicians as well as spreading and promotion of log book application. PMID- 27713072 TI - GRADE Evidence to Decision (EtD) frameworks for adoption, adaptation, and de novo development of trustworthy recommendations: GRADE-ADOLOPMENT. AB - BACKGROUND: Guideline developers can: (1) adopt existing recommendations from others; (2) adapt existing recommendations to their own context; or (3) create recommendations de novo. Monetary and nonmonetary resources, credibility, maximization of uptake, as well as logical arguments should guide the choice of the approach and processes. OBJECTIVES: To describe a potentially efficient model for guideline production based on adoption, adaptation, and/or de novo development of recommendations utilizing the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Evidence to Decision (EtD) frameworks. STUDY DESIGN AND SETTING: We applied the model in a new national guideline program producing 22 practice guidelines. We searched for relevant evidence that informs the direction and strength of a recommendation. We then produced GRADE EtDs for guideline panels to develop recommendations. RESULTS: We produced a total of 80 EtD frameworks in approximately 4 months and 146 EtDs in approximately 6 months in two waves. Use of the EtD frameworks allowed panel members understand judgments of others about the criteria that bear on guideline recommendations and then make their own judgments about those criteria in a systematic approach. CONCLUSION: The "GRADE-ADOLOPMENT" approach to guideline production combines adoption, adaptation, and, as needed, de novo development of recommendations. If developers of guidelines follow EtD criteria more widely and make their work publically available, this approach should prove even more useful. PMID- 27713073 TI - A chronological review of experimental infection studies of the role of wild animals and livestock in the maintenance and transmission of Crimean-Congo hemorrhagic fever virus. AB - This article provides a definitive review of experimental studies of the role of wild animals and livestock in the maintenance and transmission of Crimean-Congo hemorrhagic fever virus (CCHFV), the etiologic agent of Crimean-Congo hemorrhagic fever (CCHF), beginning with the first recognized outbreak of the human disease in Crimea in 1944. Published reports by researchers in the former Soviet Union, Bulgaria, South Africa, and other countries where CCHF has been observed show that CCHFV is maintained in nature in a tick-vertebrate-tick enzootic cycle. Human disease most commonly results from the bite of an infected tick, but may also follow crushing of infected ticks or exposure to the blood and tissues of infected animals during slaughter. Wild and domestic animals are susceptible to infection with CCHFV, but do not develop clinical illness. Vertebrates are important in CCHF epidemiology, as they provide blood meals to support tick populations, transport ticks across wide geographic areas, and transmit CCHFV to ticks and humans during the period of viremia. Many aspects of vertebrate involvement in the maintenance and spread of CCHFV are still poorly understood. Experimental investigations in wild animals and livestock provide important data to aid our understanding of CCHFV ecology. This article is the second in a series of reviews of more than 70 years of research on CCHF, summarizing important findings, identifying gaps in knowledge, and suggesting directions for future research. PMID- 27713076 TI - Fear of Movement Is Not Associated With Objective and Subjective Physical Activity Levels in Chronic Nonspecific Low Back Pain. AB - OBJECTIVES: To assess the association of physical activity measures, derived with an accelerometer and a self-reported questionnaire, with fear of movement in patients with chronic nonspecific low back pain (LBP) and to investigate the association between disability and fear of movement in this population. DESIGN: Cross-sectional study. SETTING: Outpatient physical therapy university clinics. PARTICIPANTS: Patients (N=119) presenting with nonspecific LBP of >3 months' duration. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Physical activity levels measured objectively with an accelerometer (ie, counts per minute, time spent in moderate-to-vigorous and light physical activity per day, number of steps per day, and number of 10-minute bouts of moderate-to-vigorous physical activity per day) and subjectively with a self-reported questionnaire (Baecke Physical Activity Questionnaire); fear of movement (Tampa Scale of Kinesiophobia); pain (11-point numerical rating scale); disability (Roland Morris Disability Questionnaire); and depression (Beck Depression Inventory). The associations were examined with correlational, univariate, and multivariable linear regression analyses. RESULTS: None of the objective physical activity measures were associated with fear of movement. The apparent association of self reported physical activity levels with fear of movement (correlational analyses: r=-.18; P<.05; univariate regression analyses: beta=-.04; 95% confidence interval [CI], -.07 to -.01; P=.04) was not confirmed in multivariable analyses. Fear of movement was consistently associated with disability in both correlational (r=.42; P<.01) and multivariable (beta=.21; 95% CI, .11-.31; P<.001) analyses. CONCLUSIONS: Our data support one aspect of the fear-avoidance model-that higher fear of movement is associated with more disability-but not the aspect of the model linking fear of movement with inactivity. PMID- 27713074 TI - An influenza A virus (H7N9) anti-neuraminidase monoclonal antibody with prophylactic and therapeutic activity in vivo. AB - Zoonotic A(H7N9) avian influenza viruses emerged in China in 2013 and continue to be a threat to human public health, having infected over 800 individuals with a mortality rate approaching 40%. Treatment options for people infected with A(H7N9) include the use of neuraminidase (NA) inhibitors. However, like other influenza viruses, A(H7N9) can become resistant to these drugs. The use of monoclonal antibodies is a rapidly developing strategy for controlling influenza virus infection. Here we generated a murine monoclonal antibody (3c10-3) directed against the NA of A(H7N9) and show that prophylactic systemic administration of 3c10-3 fully protected mice from lethal challenge with wild-type A/Anhui/1/2013 (H7N9). Further, post-infection treatment with a single systemic dose of 3c10-3 at either 24, 48 or 72 h post A(H7N9) challenge resulted in both dose- and time dependent protection of up to 100% of mice, demonstrating therapeutic potential for 3c10-3. Epitope mapping revealed that 3c10-3 binds near the enzyme active site of NA, and functional characterization showed that 3c10-3 inhibits the enzyme activity of NA and restricts the cell-to-cell spread of the virus in cultured cells. Affinity analysis also revealed that 3c10-3 binds equally well to recombinant NA of wild-type A/Anhui/1/2013 and to a variant NA carrying a R289K mutation known to infer NAI resistance. These results suggest that 3c10-3 has the potential to be used as a therapeutic to treat A(H7N9) infections either as an alternative to, or in combination with, current NA antiviral inhibitors. PMID- 27713077 TI - Noninfectious complications in patients with pediatric-onset common variable immunodeficiency correlated with defects in somatic hypermutation but not in class-switch recombination. AB - BACKGROUND: Common variable immunodeficiency (CVID) is a heterogeneous syndrome characterized by impaired immunoglobulin production and usually presents with a normal quantity of peripheral B cells. Most attempts aiming to classify these patients have mainly been focused on T- or B-cell phenotypes and their ability to produce protective antibodies, but it is still a major challenge to find a suitable classification that includes the clinical and immunologic heterogeneity of these patients. OBJECTIVE: In this study we evaluated the late stages of B cell differentiation in a heterogeneous population of patients with pediatric onset CVID to clinically correlate and assess their ability to perform somatic hypermutation (SHM), class-switch recombination (CSR), or both. METHODS: We performed a previously reported assay, the restriction enzyme hotspot mutation assay (IgkappaREHMA), to evaluate in vivo SHM status. We amplified switch regions from genomic DNA to investigate the quality of the double-strand break repairs in the class-switch recombination process in vivo. We also tested the ability to generate immunoglobulin germline and circle transcripts and to upregulate the activation-induced cytidine deaminase gene through in vitro T-dependent and T independent stimuli. RESULTS: Our results showed that patients could be classified into 2 groups according to their degree of SHM alteration. This stratification showed a significant association between patients of group A, severe alteration, and the presence of noninfectious complications. Additionally, 60% of patients presented with increased microhomology use at switched regions. In vitro activation revealed that patients with CVID behaved heterogeneously in terms of responsiveness to T-dependent stimuli. CONCLUSIONS: The correlation between noninfectious complications and SHM could be an important tool for physicians to further characterize patients with CVID. This categorization would help to improve elucidation of the complex mechanisms involved in B-cell differentiation pathways. PMID- 27713075 TI - Quality and Equity in Wheelchairs Used by Veterans. AB - OBJECTIVES: To assess in Veterans with spinal cord injury (SCI) or amputated limb (AL) the following: (1) patient demographics, medical factors, cultural and psychosocial characteristic by race; (2) wheelchair quality by race; and (3) the independent associations of patient race and the other factors with wheelchair quality. DESIGN: Cross-sectional cohort study. SETTING: Three Department of Veterans Affairs (VA) medical centers affiliated with academic medical centers. PARTICIPANTS: Eligible participants were Veterans with SCI or ALs (N=516); 482 of them completed the interview. Analyses were restricted to white and African American participants. Because there was no variation in wheelchair quality among AL patients (n=42), they were excluded from all but descriptive analyses, leading to a final sample size of 421. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Wheelchair quality as defined by the Medicare Healthcare Common Procedure Coding System. RESULTS: We found race differences in many of our variables, but not in quality for manual (odds ratio [OR]=.67; 95% confidence interval [CI], .33-1.36) or power (OR=.82; 95% CI, .51-1.34) wheelchairs. Several factors including age (OR=.96; 95% CI, .93-.99) and income (OR=3.78; 95% CI, 1.43 9.97) were associated with wheelchair quality. There were no significant associations of cultural or psychosocial factors with wheelchair quality. CONCLUSIONS: Although there were no racial differences in wheelchair quality, we found a significant association of older age and lower income with poorer wheelchair quality among Veterans. Efforts are needed to raise awareness of such disparities among VA wheelchair providers and to take steps to eliminate these disparities in prescription practice across VA sites. PMID- 27713079 TI - Corrigendum to "The transport mechanism of the mitochondrial ADP/ATP carrier" [Biochim. Biophys. Acta 1863/10 (2016) 2379-2393]. PMID- 27713078 TI - Cardiac ankyrin repeat protein attenuates cardiomyocyte apoptosis by upregulation of Bcl-2 expression. AB - Cardiac ankyrin repeat protein (CARP) is a nuclear transcriptional co-factor that has additional functions in the myoplasm as a component of the muscle sarcomere. Previous studies have demonstrated increased expression of CARP in cardiovascular diseases, however, its role in cardiomyocyte apoptosis is unclear and controversial. In the present study, we investigated possible roles of CARP in hypoxia/reoxygenation (H/R) -induced cardiomyocyte apoptosis and the underlying mechanisms. Neonatal mouse ventricular cardiomyocytes were isolated and infected with adenovirus encoding Flag-tagged CARP (Ad-CARP) and lentivirus encoding CARP targeted shRNA (sh-CARP), respectively. Cardiomyocyte apoptosis induced by exposure to H/R conditions was evaluated by TUNEL staining and western blot analysis of cleaved caspase-3. The results showed that H/R-induced apoptosis was significantly decreased in Ad-CARP cardiomyocytes and increased in sh-CARP cardiomyocytes, suggesting a protective anti-apoptosis role for CARP. Interestingly, over-expressed CARP was mainly distributed in the nucleus, consistent with its role in regulating transcriptional activity. qPCR analysis showed that Bcl-2 transcripts were significantly increased in Ad-CARP cardiomyocytes. ChIP and co-IP assays confirmed the binding of CARP to the Bcl-2 promoter through interaction with transcription factor GATA4. Collectively, our results suggest that CARP can protect against H/R induced cardiomyocyte apoptosis, possibly through increasing anti-apoptosis Bcl-2 gene expression. PMID- 27713080 TI - Synthetic and editing reactions of aminoacyl-tRNA synthetases using cognate and non-cognate amino acid substrates. AB - The covalent coupling of cognate amino acid-tRNA pairs by corresponding aminoacyl tRNA synthetases (aaRS) defines the genetic code and provides aminoacylated tRNAs for ribosomal protein synthesis. Besides the cognate substrate, some non-cognate amino acids may also compete for tRNA aminoacylation. However, their participation in protein synthesis is generally prevented by an aaRS proofreading activity located in the synthetic site and in a separate editing domain. These mechanisms, coupled with the ability of certain aaRSs to discriminate well against non-cognate amino acids in the synthetic reaction alone, define the accuracy of the aminoacylation reaction. aaRS quality control may also act as a gatekeeper for the standard genetic code and prevents infiltration by natural amino acids that are not normally coded for protein biosynthesis. This latter finding has reinforced interest in understanding the principles that govern discrimination against a range of potential non-cognate amino acids. This paper presents an overview of the kinetic assays that have been established for monitoring synthetic and editing reactions with cognate and non-cognate amino acid substrates. Taking into account the peculiarities of non-cognate reactions, the specific controls needed and the dedicated experimental designs are discussed in detail. Kinetic partitioning within the synthetic and editing sites controls the balance between editing and aminoacylation. We describe in detail steady state and single-turnover approaches for the analysis of synthetic and editing reactions, which ultimately enable mechanisms of amino acid discrimination to be determined. PMID- 27713081 TI - TrackMate: An open and extensible platform for single-particle tracking. AB - We present TrackMate, an open source Fiji plugin for the automated, semi automated, and manual tracking of single-particles. It offers a versatile and modular solution that works out of the box for end users, through a simple and intuitive user interface. It is also easily scriptable and adaptable, operating equally well on 1D over time, 2D over time, 3D over time, or other single and multi-channel image variants. TrackMate provides several visualization and analysis tools that aid in assessing the relevance of results. The utility of TrackMate is further enhanced through its ability to be readily customized to meet specific tracking problems. TrackMate is an extensible platform where developers can easily write their own detection, particle linking, visualization or analysis algorithms within the TrackMate environment. This evolving framework provides researchers with the opportunity to quickly develop and optimize new algorithms based on existing TrackMate modules without the need of having to write de novo user interfaces, including visualization, analysis and exporting tools. The current capabilities of TrackMate are presented in the context of three different biological problems. First, we perform Caenorhabditis-elegans lineage analysis to assess how light-induced damage during imaging impairs its early development. Our TrackMate-based lineage analysis indicates the lack of a cell-specific light-sensitive mechanism. Second, we investigate the recruitment of NEMO (NF-kappaB essential modulator) clusters in fibroblasts after stimulation by the cytokine IL-1 and show that photodamage can generate artifacts in the shape of TrackMate characterized movements that confuse motility analysis. Finally, we validate the use of TrackMate for quantitative lifetime analysis of clathrin-mediated endocytosis in plant cells. PMID- 27713082 TI - Cytotoxic melodinus-type alkaloids from the ethanol extract of Melodinus fusiformis. AB - A chemical investigation of the ethanol extract of the aerial parts of Melodinus fusiformis led to the isolation of six new melodinus-type alkaloids, melofusines A-E (1-6), along with one known compound, melodinine B. Structural elucidation of all the compounds was performed by spectral methods such as 1D and 2D NMR, IR, UV and HRESIMS. The isolated compounds were tested in vitro for cytotoxic potential against six tumor cell lines (Hep-2, SCL-1, CAL-27, UMSCC-1, Detroit-562 and TCA 83). As a result, compound 1 exhibited significant cytotoxic activities against all tested tumor cell lines with IC50 values <5MUM. PMID- 27713083 TI - The antihypercholesterolemic effect of columbamine from Rhizoma Coptidis in HFHC diet induced hamsters through HNF-4alpha/FTF-mediated CYP7A1 activation. AB - The aim of this study was to investigate the antihypercholesterolemic activity and potential molecular mechanism of columbamine (COL) that was prepared by extraction from Rhizoma Coptidis in hamsters and HepG2 cells. The results displayed that the COL from Rhizoma Coptidis was a safe natural compound with a LD50 0f 1524.6mg/kg and no detectable toxic symptoms during the observation of chronic toxicity. COL dose-dependently reversed the abnormal lipid levels induced by HFHC diet. Specifically, COL(M) and COL(H) significantly reduced the blood lipid levels(TC, TG and LDL-c) and enhanced the fecal contents of TBA by 21.8% and 25.1% respectively in hamsters. COL up-regulated the genes of CYP8B1, CYP7A1 and LDLR in mRNA and protein level, and down-regulated those of HMGCR to a different degree. Especially, CYP7A1 were significantly up-regulated by COL in hamsters (p<0.01). Further analysis indicated that COL obviously activated the mRNA and protein expression of the transcription factors FTF, HNF-4alpha, and inhibited those of SHP. Promoter luciferase assay showed that COL induced the expression of FTF and HNF-4alpha, further transactivating CYP7A1, which accelerated the conversion of liver cholesterol to bile acids. It concluded that the COL showed high lipid-lowering activities through indirectly transactivating CYP7A1 by upregulating FTF and HNF-4alpha, and directly activating CYP7A1 catalytic activity by strongly interacting with receptor and ligand, therefore promoting cholesterol catabolism and accelerating the excretion of bile acids. PMID- 27713084 TI - Pseudolaric acid B induces mitotic arrest and apoptosis in both 5-fluorouracil sensitive and -resistant colorectal cancer cells. AB - 5-fluorouracil (5-FU)-based chemotherapy is the main chemotherapeutic approach for colorectal cancer (CRC) treatment. Because chemoresistance occurs frequently and significantly limits CRC therapies, a novel agent is needed. Pseudolaric acid B (PAB), a small molecule derived from the Chinese medicinal herb ''Tujinpi'', exhibits strong cytotoxic effects on a variety of cancers. However, the detailed mechanisms by which PAB inhibits CRC cell growth and its potential role in overcoming 5-FU resistance have not been well studied. In this study, we showed that PAB significantly inhibited the viability of various CRC cell lines but induced minor cytotoxicity in normal cells. Both the in vitro and in vivo results showed that PAB induced proliferation inhibition, mitotic arrest and subsequently caspase-dependent apoptosis in both 5-FU-sensitive and -resistant CRC cells. Moreover, PAB was shown to interfere with CRC cell mitotic spindle apparatus and activate the spindle assembly checkpoint. Finally, CDK1 activity was involved in PAB-induced mitotic arrest and apoptosis in CRC cells. Taken together, these data reveal that PAB induces CRC cell mitotic arrest followed by apoptosis and overcomes 5-FU resistance in vitro and in vivo, suggesting that PAB may be a potential agent for CRC treatment, particularly for 5-FU-resistant CRC. PMID- 27713085 TI - The effect of high-fat diet consumption on appetitive instrumental behavior in rats. AB - Evidence now indicates that the chronic consumption of high-calorie foods, such as a high-fat diet (HFD), is associated with impaired control over food-seeking, yet the extent of this alteration is not fully understood. Using different reinforcement schedules, we evaluated whether HFD intake from weaning to adulthood modifies instrumental responding and induces a shift from goal-directed actions to habitual responding. We first observed reduced instrumental performance and motivation for a food reward in HFD-fed rats trained under schedules of reinforcement that facilitate habitual responding [Random Interval (RI)]. However, this deficit was alleviated if rats trained under RI were subsequently trained with reinforcement schedules that promote goal-directed strategies [Random Ratio (RR)]. Using an outcome devaluation procedure, we then demonstrated that consumption of a HFD promoted habitual behavior in rats trained under RI but not RR schedules. Finally, extended HFD exposure did not interfere with the ability of RR training to overcome impaired RI instrumental performance and to favor goal-directed behavior. These results indicate that chronic consumption of a HFD changes the co-ordination of goal-directed actions and habits and that alteration of food-seeking may be reversed under particular behavioral conditions. PMID- 27713087 TI - A nanovehicle developed for treating deep-seated bacteria using low-dose X-ray. AB - : Many non-antibiotic strategies, such as photocatalysis and photodynamic therapy, have been proposed to inhibit and/or kill bacteria. However, these approaches still have drawbacks such as insufficient bacterial specificity and the limited penetration depth of ultraviolet and near-infrared light. To overcome these limitations, we developed a bacteria-specific anti-bacterial technique via using low-dose X-ray. Graphene oxide quantum dots (GQDs, a multifunctional vehicle) conjugated with vancomycin (Van, a bacteria-targeting ligand) were assembled with Protoporphyrin IX (PpIX, a photo/radiation sensitizer) to yield a novel Van-GQDs/PpIX complex that specifically attached to Escherichia coli and efficiently generated intracellular reactive oxygen species following X-ray activation. Delivery using GQDs increased the PpIX/Van ratio in the target bacterial cell, damaged bacterial cell wall, and enhanced X-ray-induced PpIX activation. Hence, this approach allowed for the use of a low-dose X-ray to efficiently activate the Van-GQDs/PpIX complex to exert its bactericidal effects on Escherichia coli without damaging normal cells. Furthermore, the E. coli did not develop resistance to the proposed approach for at least 7 rounds of repeated administration during one week. Thus, this proposed vehicle exhibiting bacteria specific X-ray-triggered toxicity is a promising alternative to antibiotics for treating serious bacterial infections occurring in deep-seated tissues/organs (e.g., osteomyelitis and peritonitis). STATEMENTS OF SIGNIFICANCE: Administration of antibiotics is the most common treatment modality for bacterial infections. However, in some cases, patient attributes such as age, health, tolerance to antibiotics do not allow for the use of high-dose antibiotics. In addition, some bacteria develop resistance to antibiotics because of improper and long-term use of these agents. Therefore, non-antibiotic strategies to treat deeply situated bacterial infections, such as osteomyelitis, are urgently needed for avoiding amputation. To date, several non-antibiotic approaches, such as Ag nanoparticles, graphene-based materials, photocatalysis, and photodynamic therapy have been proposed to inhibit and/or kill bacteria. However, the major challenges of photochemical strategies, specificity and limited penetration depth of light source, still remain for treating the deep-seated bacteria. To overcome these problems, we developed a novel nanovehicle that exerted toxic effects specifically on bacteria following activation by a deeply penetrative low-dose X ray, without damaging normal cells. As such, it realizes a deeply photochemical route for treating the deep-seated bacteria. PMID- 27713086 TI - Silk-based biomaterials functionalized with fibronectin type II promotes cell adhesion. AB - : The objective of this work was to exploit the fibronectin type II (FNII) module from human matrix metalloproteinase-2 as a functional domain for the development of silk-based biopolymer blends that display enhanced cell adhesion properties. The DNA sequence of spider dragline silk protein (6mer) was genetically fused with the FNII coding sequence and expressed in Escherichia coli. The chimeric protein 6mer+FNII was purified by non-chromatographic methods. Films prepared from 6mer+FNII by solvent casting promoted only limited cell adhesion of human skin fibroblasts. However, the performance of the material in terms of cell adhesion was significantly improved when 6mer+FNII was combined with a silk elastin-like protein in a concentration-dependent behavior. With this work we describe a novel class of biopolymer that promote cell adhesion and potentially useful as biomaterials for tissue engineering and regenerative medicine. STATEMENT OF SIGNIFICANCE: This work reports the development of biocompatible silk-based composites with enhanced cell adhesion properties suitable for biomedical applications in regenerative medicine. The biocomposites were produced by combining a genetically engineered silk-elastin-like protein with a genetically engineered spider-silk-based polypeptide carrying the three domains of the fibronectin type II module from human metalloproteinase-2. These composites were processed into free-standing films by solvent casting and characterized for their biological behavior. To our knowledge this is the first report of the exploitation of all three FNII domains as a functional domain for the development of bioinspired materials with improved biological performance. The present study highlights the potential of using genetically engineered protein-based composites as a platform for the development of new bioinspired biomaterials. PMID- 27713088 TI - Comparison of three lymph node classifications for survival prediction in distant metastatic gastric cancer. AB - BACKGROUND: The optimal lymph node (LN) classification system for prognostic assessment in distant metastatic gastric cancer (DMGC) patients who undergo LN dissection remains unclear. Therefore, we compared the prognostic performance of positive LN (PLN), LN ratio (LNR), and log odds of positive LNs (LODDS) in DMGC patients. METHODS: A total of 1999 DMGC patients who underwent lymphadenectomy recorded in the Surveillance Epidemiology and End Results database from 2004 to 2012 were reviewed. RESULTS: Univariate analyses showed that the PLN, LNR and LODDS systems were all significantly correlated with cancer-specific survival (CSS). However, only the LODDS classification remained an independent prognostic factor through the multivariate analysis. Furthermore, this classification could efficiently discriminate survival outcomes in patients within the same positive PLN category, as well as in patients with no positive node involvement. Both the LODDS and LNR classifications had better discriminatory ability, monotonicity, and homogeneity of prognostic stratification, as well as more accurate 1 or 2 year CSS prediction, than the PLN classification. The performances of the LNR and LODDS classifications were similar. Additionally, we found that inclusion of PORT carried a survival benefit across all LODDS intervals except the "LODDS <= -1.0" subgroup. CONCLUSION: Our findings indicate that the LODDS classification is the most optimal system for prognostic assessment in DMGC patients. Incorporating LODDS into the staging system of DMGC patients will enable clinicians to more accurately predict prognosis and guide regional therapy regimen decisions in DMGC patients. PMID- 27713089 TI - The Fibrodysplasia Ossificans Progressiva (FOP) mutation p.R206H in ACVR1 confers an altered ligand response. AB - Patients with Fibrodysplasia Ossificans Progressiva (FOP) suffer from ectopic bone formation, which progresses during life and results in dramatic movement restrictions. Cause of the disease are point mutations in the Activin A receptor type 1 (ACVR1), with p.R206H being most common. In this study we compared the signalling responses of ACVR1WT and ACVR1R206H to different ligands. ACVR1WT, but not ACVR1R206H inhibited BMP signalling of BMP2 or BMP4 in a ligand binding domain independent manner. Likewise, the basal BMP signalling activity of the receptor BMPR1A or BMPR1B was inhibited by ACVR1WT, but enhanced by ACVR1R206H. In comparison, BMP6 or BMP7 activated ACVR1WT and caused a hyper-activation of ACVR1R206H. These effects were dependent on an intact ligand binding domain. Finally, the neofunction of Activin A in FOP was tested and found to depend on the ligand binding domain for activating ACVR1R206H. We conclude that the FOP mutation ACVR1R206H is more sensitive to a number of natural ligands. The mutant receptor apparently lost some essential inhibitory interactions with its ligands and co-receptors, thereby conferring an enhanced ligand-dependent signalling and stimulating ectopic bone formation as observed in the patients. PMID- 27713090 TI - A Comprehensive Assessment of Toxicities in Patients with Central Nervous System Lymphoma Undergoing Autologous Stem Cell Transplantation Using Thiotepa, Busulfan, and Cyclophosphamide Conditioning. AB - High-dose therapy and autologous stem cell transplantation (ASCT) with thiotepa, busulfan, and cyclophosphamide (TBC) conditioning has emerged as an effective postinduction treatment strategy for patients with primary central nervous system lymphoma (PCNSL) or secondary central nervous system lymphoma (SCNSL), but it is associated with considerable toxicity and transplantation-related mortality (TRM) in the modern era. Forty-three adult patients with chemosensitive PCNSL or SCNSL underwent TBC-conditioned ASCT between 2006 and 2015. Twenty-eight of these patients received pharmacokinetically (PK)-targeted busulfan dosing. The median number of clinically relevant individual grade >=3 nonhematologic toxicities per patient was 5. We found no association between pretransplantation patient characteristics and the presence of more than 5 grade >=3 nonhematologic toxicities. Patients with elevated first-dose busulfan area under the curve values did not experience more toxicity. Paradoxically, patients treated with more than 2 regimens before undergoing ASCT had lower first-dose busulfan AUC values. With a median follow-up among survivors of 20 months, 1-year progression free survival (PFS) and overall survival (OS) from the time of ASCT were 83% and 87%, respectively. Although this study reaffirms the favorable PFS and OS associated with TBC-conditioned ASCT for PCNSL or SCNSL, this treatment strategy carries a large toxicity burden. PMID- 27713091 TI - National Institutes of Health Blood and Marrow Transplant Late Effects Initiative: The Healthcare Delivery Working Group Report. AB - Hematopoietic cell transplantation (HCT) survivors are at risk for development of late complications and require lifelong monitoring for screening and prevention of late effects. There is an increasing appreciation of the issues related to healthcare delivery and coverage faced by HCT survivors. The 2016 National Institutes of Health Blood and Marrow Transplant Late Effects Initiative included an international and broadly representative Healthcare Delivery Working Group that was tasked with identifying research gaps pertaining to healthcare delivery and to identify initiatives that may yield a better understanding of the long term value and costs of care for HCT survivors. There is a paucity of literature in this area. Critical areas in need of research include pilot studies of novel and information technology supported models of care delivery and coverage for HCT survivors along with development and validation of instruments that capture patient-reported outcomes. Investment in infrastructure to support this research, such as linkage of databases including electronic health records and routine inclusion of endpoints that will inform analyses focused around care delivery and coverage, is required. PMID- 27713093 TI - Cross-generational effects of parental low dose BPA exposure on the Gonadotropin Releasing Hormone3 system and larval behavior in medaka (Oryzias latipes). AB - Growing evidence indicates that chronic exposure to Bisphenol A (BPA) may disrupt normal brain function and behavior mediated by gonadotropin-releasing hormone (GnRH) pathways. Previous studies have shown that low dose BPA (200ng/ml) exposure during embryogenesis altered development of extra-hypothalamic GnRH3 systems and non-reproductive locomotor behavior in medaka. Effects of parental low-dose BPA exposure on the development of GnRH3 systems and locomotor behavior of offspring are not well known. This study examines whether the neurophysiological and behavioral effects of BPA in parents (F0 generation) are carried over to their offspring (F1 generation) using stable transgenic medaka embryos/larvae with GnRH3 neurons tagged with green fluorescent protein (GFP). Parental fish were exposed to BPA (200ng/ml) for either life-long or different developmental time windows. Fertilized F1 eggs were collected and raised in egg/fish water with no environmental exposure to BPA. All experiments were performed on F1 embryos/larvae, which were grouped based on the following parental (F0) BPA exposure conditions - (i) Group 1 (G1): through life; (ii) G2: during embryogenesis and early larval development [1-14days post fertilization (dpf)]; (iii) G3: during neurogenesis (1-5dpf); and (iv) G4: during sex differentiation (5-14dpf). Embryos from unexposed vehicle treated parents served as controls (G0). G1 embryos showed significantly reduced survival rates and delayed hatching time compared to other groups, while G4 embryos hatched significantly earlier than all other groups. At 3 dpf, the GnRH3-GFP intensity was increased by 47% in G3 embryos and decreased in G4 embryos by 59% compared to controls. At 4dpf, G1 fish showed 42% increased intensity, while GFP intensity was reduced by 44% in G3 subjects. In addition, the mean brain size of G1, G3 and G4 embryos were smaller than that of control at 4dpf. At 20dpf, all larvae from BPA-treated parents showed significantly decreased total movement (distance covered) compared with controls, with G2 and G3 fish showing reduced velocity of movement. While at 20 dpf no group differences were seen in the soma diameter of GnRH3-GFP neurons, a 34% decrease in SV2 expression, a marker for synaptic transmission, in G1 larvae was observed. These data suggest that parental BPA exposure during critical windows of embryonic development or chronic treatment affects next-generation offspring both in embryonic and larval brain development as well as larval behavior. PMID- 27713094 TI - Genetic variation associated with the occurrence and progression of neurological disorders. AB - This paper presents an overview of genetic variation associated with the onset and progression of 14 neurological disorders, focusing primarily on association studies. The 14 disorders are heterogeneous in terms of their frequency, age of onset, etiology and progression. There is substantially less evidence on progression than onset. With regard to onset, the conditions are diverse in terms of their epidemiology and patterns of familial aggregation. While the muscular dystrophies and Huntington's disease are monogenic diseases, for the other 12 conditions only a small proportion of cases is associated with specific genetic syndromes or mutations. Excluding these, some familial aggregation remains for the majority of cases. There is considerable variation in the volume of evidence by condition, and by gene within condition. The volume of evidence is greatest for Alzheimer's disease, Parkinson's disease, multiple sclerosis and amyotrophic lateral sclerosis. As for common complex chronic diseases, genome wide association studies have found that validated genomic regions account for a low proportion of heritability. Apart from multiple sclerosis, which shares several susceptibility loci with other immune-related disorders, variation at HLA-DRB5 being associated both with Parkinson's disease and Alzheimer's disease, and the association of the C9orf72 repeat expansion with ALS and frontotemporal degeneration, there was little evidence of gene loci being consistently associated with more than one neurological condition or with other conditions. With the exception of spina bifida, for which maternal MTHFR genotype is associated with risk in the offspring, and corroborates other evidence of the importance of folate in etiology, there was little evidence that the pathways influenced by genetic variation are related to known lifestyle or environmental exposures. PMID- 27713095 TI - Nutrition for the ageing brain: Towards evidence for an optimal diet. AB - As people age they become increasingly susceptible to chronic and extremely debilitating brain diseases. The precise cause of the neuronal degeneration underlying these disorders, and indeed normal brain ageing remains however elusive. Considering the limits of existing preventive methods, there is a desire to develop effective and safe strategies. Growing preclinical and clinical research in healthy individuals or at the early stage of cognitive decline has demonstrated the beneficial impact of nutrition on cognitive functions. The present review is the most recent in a series produced by the Nutrition and Mental Performance Task Force under the auspice of the International Life Sciences Institute Europe (ILSI Europe). The latest scientific advances specific to how dietary nutrients and non-nutrient may affect cognitive ageing are presented. Furthermore, several key points related to mechanisms contributing to brain ageing, pathological conditions affecting brain function, and brain biomarkers are also discussed. Overall, findings are inconsistent and fragmented and more research is warranted to determine the underlying mechanisms and to establish dose-response relationships for optimal brain maintenance in different population subgroups. Such approaches are likely to provide the necessary evidence to develop research portfolios that will inform about new dietary recommendations on how to prevent cognitive decline. PMID- 27713096 TI - Regulation of Mitofusin1 by Mahogunin Ring Finger-1 and the proteasome modulates mitochondrial fusion. AB - Health and homoeostasis are maintained by a dynamic balance between mitochondrial fission and fusion. Mitochondrial fusion machinery is largely unknown in mammals. Only a few reports have illustrated the role of Fzo1 in mitochondrial fusion known in Saccharomyces cerevisiae. We demonstrate that the ubiquitin ligase Mahogunin Ring Finger-1 (MGRN1) interacts with and constitutively ubiquitinates the mammalian homolog, Mitofusin1 (Mfn1) via K63 linkages. In mice models, loss of Mgrn1 function leads to severe developmental defects and adult-onset spongiform neurodegeneration, similar to prion diseases. The tethering of mitochondria to form the ~180kDa Mfn1 complex is independent of MGRN1-mediated ubiquitination. However, successful mitochondrial fusion requires formation of higher oligomers of Mfn1 which in turn needs GTPase activity, intact heptad repeats of Mfn1 and ubiquitination by MGRN1. Following ubiquitination, proteasomal processing of Mfn1 completes the mitochondrial fusion process. This step requires functional p97 activity. These findings suggest a sequence of events where GTPase activity of Mfn1 and tethering of adjacent mitochondria precedes its MGRN1-mediated ubiquitination and proteasomal degradation culminating in mitochondrial fusion. PMID- 27713097 TI - Cytoplasmic RNA decay pathways - Enzymes and mechanisms. AB - RNA decay plays a crucial role in post-transcriptional regulation of gene expression. Work conducted over the last decades has defined the major mRNA decay pathways, as well as enzymes and their cofactors responsible for these processes. In contrast, our knowledge of the mechanisms of degradation of non-protein coding RNA species is more fragmentary. This review is focused on the cytoplasmic pathways of mRNA and ncRNA degradation in eukaryotes. The major 3' to 5' and 5' to 3' mRNA decay pathways are described with emphasis on the mechanisms of their activation by the deprotection of RNA ends. More recently discovered 3'-end modifications such as uridylation, and their relevance to cytoplasmic mRNA decay in various model organisms, are also discussed. Finally, we provide up-to-date findings concerning various pathways of non-coding RNA decay in the cytoplasm. PMID- 27713098 TI - First report on Babesia vogeli infection in dogs in the Philippines. AB - Babesia vogeli is a tick-borne protozoal pathogen that infects erythrocytes. In Southeast Asia, this pathogen has only been reported in Thailand. In this study, nine dogs presented at three different veterinary clinics in Cebu City, Philippines were found positive for B. vogeli. DNA was extracted from blood samples and tested using a PCR for genus Babesia and a PCR specific for B. vogeli (both based on the 18S rRNA gene). Blood smears (triplicate) from each sample were found negative. All positive amplicons were sequenced and were found to be 99.4% identical to registered B. vogeli sequences at Genbank. Phylogenetic analysis revealed monophyletic grouping of Philippine sequences with the registered A. platys Genbank sequences. This is the first report of B. vogeli infection in dogs in the Philippines. PMID- 27713099 TI - Dispelling the myth: Exploring associations between the HPV vaccine and inconsistent condom use among college students. AB - Human papillomavirus (HPV) vaccination is safe and effective in preventing anogenital cancers and warts. However, myths have surrounded the HPV vaccine since its approval, including the possibility that HPV vaccinated young people are more likely to engage in risky sexual behaviors. The purpose of this study was to assess the association between HPV vaccination and engaging in inconsistent condom use in a sample of U.S. college students. A secondary data analysis of the National College Health Assessment-II (Fall 2013) was conducted in 2015. Risky sexual activity was operationalized as inconsistent condom use for oral, vaginal or anal sexual activity. Logistic regression models were stratified by sexual activity and gender, and controlled for socio-demographics and history of STIs. Inconsistent condom use was reported among females for vaginal (47%), oral (94%), and anal sex (75%); while males reported levels of inconsistency for vaginal (38%), oral (94%), and anal sex (58%). Sixty-nine percent of females reported receiving the HPV vaccine compared to 43% of males. Among females, there was no significant association between HPV vaccination and inconsistent condom use in any of the sexual activities. Among males, there was no significant association between HPV vaccination and inconsistent condom use in oral or vaginal sex. HPV-vaccinated males were less likely to report inconsistent condom use during anal sexual activity. This study contributes to the increasing evidence that HPV vaccination is not associated with risky sexual behavior. Dispelling this myth is important to facilitate uptake and completion of the HPV vaccine in the U.S. PMID- 27713100 TI - Do cigarette health warning labels comply with requirements: A 14-country study. AB - The Framework Convention on Tobacco Control, a global health treaty ratified by over 175 countries, calls on countries to ensure that tobacco packages carry health warning labels (HWLs) describing the harmful effects of tobacco use. We assessed the extent of compliance with 14 countries' HWL requirements. Unique cigarette packs were purchased in 2013 using a systematic protocol in 12 distinct neighborhoods within three of the ten most populous cities in the 14 low- and middle-income countries with the greatest number (count) of smokers. HWL compliance codebooks were developed for each country based on the details of country-specific HWL requirements, with up to four common compliance indicators assessed for each country (location, size, label elements, text size). Packs (n=1859) were double coded for compliance. Compliance was examined by country and pack characteristics, including parent company and brand family. Overall, 72% of coded cigarette packs were compliant with all relevant compliance indicators, ranging from 17% in the Philippines to 94% in Mexico. Compliance was highest for location of the warning (ranging from 75%-100%) and lowest for warning size (ranging from 46%-99%). Compliance was higher for packs bought in high SES neighborhoods, and varied by parent company and brand family. This multi-country study found at least one pack in every country - and many packs in some countries - that were not compliant with key requirements for health warning labels in the country of purchase. Non-compliance may be exacerbating health disparities. Tobacco companies should be held accountable for complying with country HWL requirements. PMID- 27713092 TI - The Biology of Chronic Graft-versus-Host Disease: A Task Force Report from the National Institutes of Health Consensus Development Project on Criteria for Clinical Trials in Chronic Graft-versus-Host Disease. AB - Chronic graft-versus-host disease (GVHD) is the leading cause of late, nonrelapse mortality and disability in allogeneic hematopoietic cell transplantation recipients and a major obstacle to improving outcomes. The biology of chronic GVHD remains enigmatic, but understanding the underpinnings of the immunologic mechanisms responsible for the initiation and progression of disease is fundamental to developing effective prevention and treatment strategies. The goals of this task force review are as follows: This document is intended as a review of our understanding of chronic GVHD biology and therapies resulting from preclinical studies, and as a platform for developing innovative clinical strategies to prevent and treat chronic GVHD. PMID- 27713101 TI - Cardiorespiratory fitness levels and moderators in people with HIV: A systematic review and meta-analysis. AB - Cardiorespiratory fitness (CRF) is a modifiable risk factor for cardiovascular disease and premature mortality. CRF levels and moderators among people living with HIV (PLWH) are unknown. The aim of the current meta-analysis was to (1) determine mean CRF in PLWH and compare levels with age- and gender-matched healthy controls (HCs), (2) explore moderators of CRF, (3) and (4) explore moderators of CRF outcomes following physical activity (PA) interventions. Major electronic databases were searched systematically for articles reporting CRF expressed as maximum or peak oxygen uptake (ml/min/kg) in PLWH. A random effects meta-analysis calculating the pooled mean CRF including subgroup- and meta regression analyses was undertaken. Across 21 eligible studies, the CRF level was 26.4ml/kg/min (95% CI=24.6 to 28.1) (n=1010; mean age=41years). There were insufficient data to compare CRF levels with HCs. A higher body mass index (beta= 0.99, 95% CI=-1.93 to -0.06, P=0.04), older age (beta=-0.31, 95% CI=-0.58 to 0.04, P=0.02) and the presence of lipodystrophy (beta=-4.63, 95% CI=-7.88 to 1.39, P=0.005) were significant moderators of lower CRF levels. Higher CD4+ counts (beta=0.004, 95% CI=0.0007 to 0.007, P=0.016), supervised interventions (P<0.001) and interventions with a lower frequency of weekly sessions (2 or 3 versus 4 times) (P<0.001) predicted a better CRF-outcome following PA. CRF levels of PLWH are among the lowest in comparison to other vulnerable populations. More research on the most optimal physical activity intervention characteristics is needed. PMID- 27713102 TI - Pedestrian-oriented zoning is associated with reduced income and poverty disparities in adult active travel to work, United States. AB - : Active travel to work can provide additional minutes of daily physical activity. While the literature points to the relationship between zoning, equity and socioeconomic status, and physical activity, no study has quantitatively explored these connections. This study examined whether zoning may help to moderate any income and poverty inequities in active travel and taking public transit to work. Research was conducted between May 2012 and June 2015. Zoning data were compiled for 3914 jurisdictions covering 45.45% of the U.S. population located in 471 of the most populous U.S. counties and 2 consolidated cities located in 48 states and the District of Columbia. (Sensitivity analyses also captured unincorporated areas which, with the municipalities, collectively covered ~72% of the U.S. POPULATION: ) Zoning codes were obtained and evaluated to assess the pedestrian-orientation of the zoning codes. Public transit use, active travel to work, median household income, and poverty data were obtained for all study jurisdictions from the 2010-2014 American Community Survey estimates. Associations were examined through multivariate regression models, controlling for community sociodemographics, clustered on county, with robust standard errors. We found that certain pedestrian-oriented zoning provisions (e.g., crosswalks, bike-pedestrian connectivity, street connectivity, bike lanes, bike parking, and more zoning provisions) were associated with reduced income and/or poverty disparities in rates of public transit use and active travel to work. Findings from this study can help to inform cross-sectoral collaborations between the public health, planning, and transportation fields regarding zoning for pedestrian-orientation and active travel. PMID- 27713103 TI - Burden of skin cancer in Belgium and cost-effectiveness of primary prevention by reducing ultraviolet exposure. AB - Skin cancer (melanoma- and non-melanoma skin cancer) is one of the most rapidly increasing cancers worldwide. This study analysed the current and future economic burden of skin cancer in Belgium and the cost-effectiveness of primary prevention of skin cancer. A retrospective bottom-up cost-of-illness study was performed, together with a Markov model in order to analyse the cost-effectiveness and the budget impact analysis of primary prevention of skin cancer in Belgium. Total prevalence of skin cancer in Belgium was estimated to triple in the next 20years. The total economic burden of skin cancer in 2014 in Belgium was estimated at ?106 million, with a cumulative cost of ?3 billion in 2034. The majority of this total cost was due to melanoma (65%). Over a period of 50years, both a sensitisation campaign and a total ban on sunbed use would lead to a gain in quality-adjusted life-years and cost-savings. For every euro invested in the campaign, ?3.6 would be saved on the long-term for the healthcare payer. Policy makers and clinicians should promote UV protection strategies, as they were estimated to be dominant strategies. PMID- 27713104 TI - Quantitative morphometric study of the subaxial cervical vertebrae end plate. AB - BACKGROUND CONTEXT: Cervical disc arthroplasty has been gradually adopted as an alternative for the treatment of cervical degenerative disease. However, there is a large discrepancy between footprints of currently available cervical disc prostheses and anatomic dimensions of cervical end plates. PURPOSE: This study aimed to accurately and comprehensively quantify the three-dimensional (3D) anatomic morphology of the cervical vertebral end plate and provide a theoretical basis for designing appropriate disc prostheses. Moreover, we introduced a novel geometric and mechanical model for 3D reconstruction techniques of the cervical end plate. STUDY DESIGN: A descriptive study of the geometry of the middle and lower cervical vertebral end plates in cadaveric spines was carried out. METHODS: A total of 138 cervical vertebral end plates were digitized using an optical 3D range scanning system, and then each end plate was reconstructed using the digitized image. For each end plate, the morphologic characteristics of six surface curves and the end plate concavity depth were symmetrically chosen and depicted. RESULTS: The cranial end plates (relative to the disc) were concave and the caudal end plates were relatively flat at all disc levels, with mean concavity depths of 2.04 and 0.69 mm, respectively. For the caudal end plates, the end plate concavity apex was most often (81.42%) located in the posterior portion, whereas in the cranial end plates, the distribution was relatively even. For the sagittal curves, the foremost point and the rearmost point on the middle curve had a more forward position than those in the left curve and the right curve. Regarding the frontal plane curves, the length of the middle curve was longer than that of the anterior curve and posterior curve. For the cranial end plate, the maximal mean depth was the middle curve, whereas for the caudal end plate, the maximum depth was the posterior curve. CONCLUSIONS: There is marked morphologic asymmetry, in that the cranial end plate is more concave than the corresponding caudal end plate. In the sagittal plane, the caudal end plates are aerofoil-shaped, whereas the cranial end plates are arc-shaped. In the transverse plane, the end plates are kidney-shaped. These morphologic characteristics of cervical vertebral end plates should be taken into consideration when designing cervical devices, such as artificial discs. PMID- 27713105 TI - Associations between Long-Term Particulate Matter Exposure and Adult Renal Function in the Taipei Metropolis. AB - BACKGROUND: Studies on the effect of air pollutions on kidney diseases are still limited. OBJECTIVE: We aimed to investigate the associations between particulate matter (PM) exposures and renal function among adults. METHODS: We recruited 21,656 adults as participants from 2007 to 2009. The Taiwanese Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was used to derive the estimated glomerular filtration rate (eGFR). Subjects with an eGFR lower than 60 mL/min/1.73 m2 were defined as having chronic kidney disease (CKD). Land use regression (LUR) models were used to estimate individual exposures to PM with an aerodynamic diameter < 10 MUm (PM10), coarse particles (PMCoarse), fine particles (PM2.5), and PM2.5Absorbance. Generalized linear and logistic regression models were used to estimate the associations between PM exposure and renal function. RESULTS: An IQR increase in PM10 (5.83 MUg/m3) was negatively associated with eGFR by -0.69 (95% CI: -0.89, -0.48) mL/min/1.73 m2 and positively associated with the prevalence of CKD with adjusted OR = 1.15 (95% CI: 1.07, 1.23). An IQR increase in PMCoarse (6.59 MUg/m3) was significantly associated with lower eGFR by -1.07 (95% CI: -1.32, -0.81) mL/min/1.73 m2 and CKD with OR = 1.26 (95% CI: 1.15, 1.38). In contrast, neither outcome was significantly associated with PM2.5 or PM2.5Absorbance. Stratified analyses indicated that associations of CKD with both PM10 and PMCoarse were limited to participants < 65 years of age, and were stronger (for PM10) or limited to (PMCoarse) women. Associations also appeared to be stronger in those without (vs. with) hypertension, and in normal versus overweight participants. CONCLUSIONS: Exposure during the previous year to PM10 and PMCoarse, but not PM2.5 or PM2.5Absorbance, was associated with reduced renal function among Taiwanese adults. PMID- 27713106 TI - An Analysis of the Potential Impact of Climate Change on Dengue Transmission in the Southeastern United States. AB - BACKGROUND: Dengue fever, caused by a mosquito-transmitted virus, is an increasing health concern in the Americas. Meteorological variables such as temperature and precipitation can affect disease distribution and abundance through biophysical impacts on the vector and on the virus. Such tightly coupled links may facilitate further spread of dengue fever under a changing climate. In the southeastern United States, the dengue vector is widely established and exists on the current fringe of dengue transmission. OBJECTIVES: We assessed projected climate change-driven shifts in dengue transmission risk in this region. METHODS: We used a dynamic mosquito population and virus transmission model driven by meteorological data to simulate Aedes aegypti populations and dengue cases in 23 locations in the southeastern United States under current climate conditions and future climate projections. We compared estimates for each location with simulations based on observed data from San Juan, Puerto Rico, where dengue is endemic. RESULTS: Our simulations based on current climate data suggest that dengue transmission at levels similar to those in San Juan is possible at several U.S. locations during the summer months, particularly in southern Florida and Texas. Simulations that include climate change projections suggest that conditions may become suitable for virus transmission in a larger number of locations and for a longer period of time during each year. However, in contrast with San Juan, U.S. locations would not sustain year-round dengue transmission according to our model. CONCLUSIONS: Our findings suggest that Dengue virus (DENV) transmission is limited by low winter temperatures in the mainland United States, which are likely to prevent its permanent establishment. Although future climate conditions may increase the length of the mosquito season in many locations, projected increases in dengue transmission are limited to the southernmost locations. PMID- 27713107 TI - A Longitudinal Study of Peripubertal Serum Organochlorine Concentrations and Semen Parameters in Young Men: The Russian Children's Study. AB - BACKGROUND: Exposures to endocrine-disrupting chemicals during critical phases of testicular development may be related to poorer semen parameters. However, few studies have assessed the association between childhood organochlorine (OC) exposure and adult semen parameters. OBJECTIVE: We examined whether peripubertal serum OC concentrations are associated with semen parameters among young Russian men. METHODS: From 2003 through 2005, 516 boys were enrolled at age 8-9 years and followed for up to 10 years. Serum OCs were measured in the enrollment samples using high-resolution mass spectrometry. At 18-19 years, 133 young men provided 1 or 2 semen samples (256 samples) collected approximately 1 week apart, which were analyzed for volume, sperm concentration, and motility. Unadjusted and adjusted linear mixed models were used to examine the associations of quartiles of lipid standardized concentrations of dioxins [2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), polychlorinated dibenzo-p-dioxins (PCDDs)], furans, polychlorinated biphenyls (PCBs), and corresponding toxic equivalents (TEQs) with semen parameters. RESULTS: The median (range) for TCDD was 2.9 (0.4-12.1) pg/g lipid and PCDD TEQ was 8.7 (1.0-36.0) pg TEQ/g lipid. Higher quartiles of TCDD and PCDD TEQs were associated with lower sperm concentration, total sperm count, and total motile sperm count (p-trends <= 0.05). The highest quartile of peripubertal serum TCDD concentrations was associated with a decrease (95% CI) of 40% (18, 66%), 29% (3, 64%), and 30% (2, 70%) in sperm concentration, total sperm count, and total motile sperm count, respectively, compared with the lowest quartile. Similar associations were observed for serum PCDD TEQs with semen parameters. Serum PCBs, furans, and total TEQs were not associated with semen parameters. CONCLUSION: Higher peripubertal serum TCDD concentrations and PCDD TEQs were associated with poorer semen parameters.

PMID- 27713109 TI - Population-Level Exposure to Particulate Air Pollution during Active Travel: Planning for Low-Exposure, Health-Promoting Cities. AB - BACKGROUND: Providing infrastructure and land uses to encourage active travel (i.e., bicycling and walking) are promising strategies for designing health promoting cities. Population-level exposure to air pollution during active travel is understudied. OBJECTIVES: Our goals were a) to investigate population-level patterns in exposure during active travel, based on spatial estimates of bicycle traffic, pedestrian traffic, and particulate concentrations; and b) to assess how those exposure patterns are associated with the built environment. METHODS: We employed facility-demand models (active travel) and land use regression models (particulate concentrations) to estimate block-level (n = 13,604) exposure during rush-hour (1600-1800 hours) in Minneapolis, Minnesota. We used the model-derived estimates to identify land use patterns and characteristics of the street network that are health promoting. We also assessed how exposure is correlated with indicators of health disparities (e.g., household income, proportion of nonwhite residents). Our work uses population-level rates of active travel (i.e., traffic flows) rather than the probability of walking or biking (i.e., "walkability" or "bikeability") to assess exposure. RESULTS: Active travel often occurs on high traffic streets or near activity centers where particulate concentrations are highest (i.e., 20-42% of active travel occurs on blocks with high population level exposure). Only 2-3% of blocks (3-8% of total active travel) are "sweet spots" (i.e., high active travel, low particulate concentrations); sweet spots are located a) near but slightly removed from the city-center or b) on off-street trails. We identified 1,721 blocks (~ 20% of local roads) where shifting active travel from high-traffic roads to adjacent low-traffic roads would reduce exposure by ~ 15%. Active travel is correlated with population density, land use mix, open space, and retail area; particulate concentrations were mostly unchanged with land use. CONCLUSIONS: Public health officials and urban planners may use our findings to promote healthy transportation choices. When designing health-promoting cities, benefits (physical activity) as well as hazards (air pollution) should be evaluated. PMID- 27713108 TI - Chronic Exposure to Low Doses of Dioxin Promotes Liver Fibrosis Development in the C57BL/6J Diet-Induced Obesity Mouse Model. AB - BACKGROUND: Exposure to persistent organic pollutants (POPs) has been associated with the progression of chronic liver diseases, yet the contribution of POPs to the development of fibrosis in non-alcoholic fatty liver disease (NAFLD), a condition closely linked to obesity, remains poorly documented. OBJECTIVES: We investigated the effects of subchronic exposure to low doses of the POP 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD), an aryl hydrocarbon receptor ligand, on NAFLD progression in diet-induced obese C57BL/6J mice. METHODS: Male C57BL/6J mice were fed either a 10% low-fat (LFD) or a 45% high-fat (HFD) purified diet for 14 weeks and TCDD-exposed groups were injected once a week with 5 MUg/kg TCDD or the vehicle for the last 6 weeks of the diet. RESULTS: Liver histology and triglyceride levels showed that exposure of HFD fed mice to TCDD worsened hepatic steatosis, as compared to either HFD alone or LFD plus TCDD and the mRNA levels of key genes of hepatic lipid metabolism were strongly altered in co-treated mice. Further, increased liver collagen staining and serum transaminase levels showed that TCDD induced liver fibrosis in the HFD fed mice. TCDD in LFD fed mice increased the expression of several inflammation and fibrosis marker genes with no additional effect from a HFD. CONCLUSIONS: Exposure to TCDD amplifies the impairment of liver functions observed in mice fed an enriched fat diet as compared to a low fat diet. The results provide new evidence that environmental pollutants promote the development of liver fibrosis in obesity-related NAFLD in C57BL/6J mice.

PMID- 27713110 TI - Associations between Environmental Quality and Mortality in the Contiguous United States, 2000-2005. AB - BACKGROUND: Assessing cumulative effects of the multiple environmental factors influencing mortality remains a challenging task. OBJECTIVES: This study aimed to examine the associations between cumulative environmental quality and all-cause and leading cause-specific (heart disease, cancer, and stroke) mortality rates. METHODS: We used the overall Environmental Quality Index (EQI) and its five domain indices (air, water, land, built, and sociodemographic) to represent environmental exposure. Associations between the EQI and mortality rates (CDC WONDER) for counties in the contiguous United States (n = 3,109) were investigated using multiple linear regression models and random intercept and random slope hierarchical models. Urbanicity, climate, and a combination of the two were used to explore the spatial patterns in the associations. RESULTS: We found 1 standard deviation increase in the overall EQI (worse environment) was associated with a mean 3.22% (95% CI: 2.80%, 3.64%) increase in all-cause mortality, a 0.54% (95% CI: -0.17%, 1.25%) increase in heart disease mortality, a 2.71% (95% CI: 2.21%, 3.22%) increase in cancer mortality, and a 2.25% (95% CI: 1.11%, 3.39%) increase in stroke mortality. Among the environmental domains, the associations ranged from -1.27% (95% CI: -1.70%, -0.84%) to 3.37% (95% CI: 2.90%, 3.84%) for all-cause mortality, -2.62% (95% CI: -3.52%, -1.73%) to 4.50% (95% CI: 3.73%, 5.27%) for heart disease mortality, -0.88% (95% CI: -2.12%, 0.36%) to 3.72% (95% CI: 2.38%, 5.06%) for stroke mortality, and -0.68% (95% CI: -1.19%, 0.18%) to 3.01% (95% CI: 2.46%, 3.56%) for cancer mortality. Air had the largest associations with all-cause, heart disease, and cancer mortality, whereas the sociodemographic index had the largest association with stroke mortality. Across the urbanicity gradient, no consistent trend was found. Across climate regions, the associations ranged from 2.29% (95% CI: 1.87%, 2.72%) to 5.30% (95% CI: 4.30%, 6.30%) for overall EQI, and larger associations were generally found in dry areas for both overall EQI and domain indices. CONCLUSIONS: These results suggest that poor environmental quality, particularly poor air quality, was associated with increased mortality and that associations vary by urbanicity and climate region.

AB - BACKGROUND: Evaluation of short-term mortality displacement is essential to accurately estimate the impact of short-term air pollution exposure on public health. OBJECTIVES: We quantified mortality displacement by estimating single-day lag effects and cumulative effects of air pollutants on mortality using distributed lag models. METHODS: We performed a daily time series of nonaccidental and cause-specific mortality among elderly residents of Sao Paulo, Brazil, between 2000 and 2011. Effects of particulate matter smaller than 10 MUm (PM10), nitrogen dioxide (NO2) and carbon monoxide (CO) were estimated in Poisson generalized additive models. Single-day lag effects of air pollutant exposure were estimated for 0-, 1- and 2-day lags. Distributed lag models with lags of 0 10, 0-20 and 0-30 days were used to assess mortality displacement and potential cumulative exposure effects. RESULTS: PM10, NO2 and CO were significantly associated with nonaccidental and cause-specific deaths in both single-day lag and cumulative lag models. Cumulative effect estimates for 0-10 days were larger than estimates for single-day lags. Cumulative effect estimates for 0-30 days were essentially zero for nonaccidental and circulatory deaths but remained elevated for respiratory and cancer deaths. CONCLUSIONS: We found evidence of mortality displacement within 30 days for nonaccidental and circulatory deaths in elderly residents of Sao Paulo. We did not find evidence of mortality displacement within 30 days for respiratory or cancer deaths. Citation: Costa AF, Hoek G, Brunekreef B, Ponce de Leon AC. 2017.

AB - BACKGROUND: The US Department of Veterans Affairs (VA) has developed various health information technology (HIT) resources to provide accessible veteran centered health care. Currently, the VA is undergoing a major reorganization of VA HIT to develop a fully integrated system to meet consumer needs. Although extensive system documentation exists for various VA HIT systems, a more centralized and integrated perspective with clear documentation is needed in order to support effective analysis, strategy, planning, and use. Such a tool would enable a novel view of what is currently available and support identifying and effectively capturing the consumer's vision for the future. OBJECTIVE: The objective of this study was to develop the VA HIT Systems Matrix, a novel tool designed to describe the existing VA HIT system and identify consumers' vision for the future of an integrated VA HIT system. METHODS: This study utilized an expert panel and veteran informant focus groups with self-administered surveys. The study employed participatory research methods to define the current system and understand how stakeholders and veterans envision the future of VA HIT and interface design (eg, look, feel, and function). Directed content analysis was used to analyze focus group data. RESULTS: The HIT Systems Matrix was developed with input from 47 veterans, an informal caregiver, and an expert panel to provide a descriptive inventory of existing and emerging VA HIT in four worksheets: (1) access and function, (2) benefits and barriers, (3) system preferences, and (4) tasks. Within each worksheet is a two-axis inventory. The VA's existing and emerging HIT platforms (eg, My HealtheVet, Mobile Health, VetLink Kiosks, Telehealth), My HealtheVet features (eg, Blue Button, secure messaging, appointment reminders, prescription refill, vet library, spotlight, vitals tracker), and non-VA platforms (eg, phone/mobile phone, texting, non-VA mobile apps, non-VA mobile electronic devices, non-VA websites) are organized by row. Columns are titled with thematic and functional domains (eg, access, function, benefits, barriers, authentication, delegation, user tasks). Cells for each sheet include descriptions and details that reflect factors relevant to domains and the topic of each worksheet. CONCLUSIONS: This study provides documentation of the current VA HIT system and efforts for consumers' vision of an integrated system redesign. The HIT Systems Matrix provides a consumer preference blueprint to inform the current VA HIT system and the vision for future development to integrate electronic resources within VA and beyond with non-VA resources. The data presented in the HIT Systems Matrix are relevant for VA administrators and developers as well as other large health care organizations seeking to document and organize their consumer-facing HIT resources. PMID- 27713113 TI - A Web-Based Psychosocial Intervention for Family Caregivers of Older People: Results from a Mixed-Methods Study in Three European Countries. AB - BACKGROUND: Informal caregiving is the main source of care for older people in Europe. An enormous amount of responsibility and care activity is on the shoulders of family caregivers, who might experience problems in their psychological well-being and in reconciling caregiving and their personal sphere. In order to alleviate such burden, there is increasing interest and growing research in Europe on Web-based support addressing family caregivers and their needs. However, the level of development and penetration of innovative Web-based services for caregivers is still quite low and the access to traditional face-to face services can be problematic for logistic, availability, and quality reasons. OBJECTIVE: As part of the European project INNOVAGE, a pilot study was conducted for developing and testing a Web-based psychosocial intervention aimed at empowering family caregivers of older people in Italy, Sweden, and Germany. The program offered information resources and interactive services to enable both professional and peer support. METHODS: A mixed-methods, sequential explanatory design was adopted. Caregivers' psychological well-being, perceived negative and positive aspects of caregiving, and social support received were assessed before and after the 3-month intervention. Poststudy, a subsample of users participated in focus groups to assist in the interpretation of the quantitative results. RESULTS: A total of 94 out of 118 family caregivers (79.7%) from the three countries used the Web platform at least once. The information resources were used to different extents in each country, with Italian users having the lowest median number of visits (5, interquartile range [IQR] 2-8), whereas German users had the highest number (17, IQR 7-66) (P<.001). The interactive services most frequently accessed (more than 12 times) in all countries were the social network (29/73, 40%) and private messages (27/73, 37%). The pretest-posttest analysis revealed some changes, particularly the slight worsening of perceived positive values of caregiving (Carers of Older People in Europe [COPE] positive value subscale: P=.02) and social support received (COPE quality-of-support subscale: P=.02; Multidimensional Scale of Perceived Social Support subscale: P=.04), in all cases with small effect size (r range -.15 to -.18). Focus groups were conducted with 20 family caregivers and the content analysis of discussions identified five main themes: online social support, role awareness, caregiving activities, psychological well-being, and technical concerns. The analysis suggested the intervention was useful and appropriate, also stimulating a better self-efficacy and reappraisal of the caregivers' role. CONCLUSIONS: The intervention seemed to contribute to the improvement of family caregivers' awareness, efficacy, and empowerment, which in turn may lead to a better self recognition of their own needs and improved efforts for developing and accessing coping resources. A major implication of the study was the finalization and implementation of the InformCare Web platform in 27 European countries, now publicly accessible (www.eurocarers.org/informcare). PMID- 27713114 TI - Influence of Pedometer Position on Pedometer Accuracy at Various Walking Speeds: A Comparative Study. AB - BACKGROUND: Demographic growth in conjunction with the rise of chronic diseases is increasing the pressure on health care systems in most OECD countries. Physical activity is known to be an essential factor in improving or maintaining good health. Walking is especially recommended, as it is an activity that can easily be performed by most people without constraints. Pedometers have been extensively used as an incentive to motivate people to become more active. However, a recognized problem with these devices is their diminishing accuracy associated with decreased walking speed. The arrival on the consumer market of new devices, worn indifferently either at the waist, wrist, or as a necklace, gives rise to new questions regarding their accuracy at these different positions. OBJECTIVE: Our objective was to assess the performance of 4 pedometers (iHealth activity monitor, Withings Pulse O2, Misfit Shine, and Garmin vivofit) and compare their accuracy according to their position worn, and at various walking speeds. METHODS: We conducted this study in a controlled environment with 21 healthy adults required to walk 100 m at 3 different paces (0.4 m/s, 0.6 m/s, and 0.8 m/s) regulated by means of a string attached between their legs at the level of their ankles and a metronome ticking the cadence. To obtain baseline values, we asked the participants to walk 200 m at their own pace. RESULTS: A decrease of accuracy was positively correlated with reduced speed for all pedometers (12% mean error at self-selected pace, 27% mean error at 0.8 m/s, 52% mean error at 0.6 m/s, and 76% mean error at 0.4 m/s). Although the position of the pedometer on the person did not significantly influence its accuracy, some interesting tendencies can be highlighted in 2 settings: (1) positioning the pedometer at the waist at a speed greater than 0.8 m/s or as a necklace at preferred speed tended to produce lower mean errors than at the wrist position; and (2) at a slow speed (0.4 m/s), pedometers worn at the wrist tended to produce a lower mean error than in the other positions. CONCLUSIONS: At all positions, all tested pedometers generated significant errors at slow speeds and therefore cannot be used reliably to evaluate the amount of physical activity for people walking slower than 0.6 m/s (2.16 km/h, or 1.24 mph). At slow speeds, the better accuracy observed with pedometers worn at the wrist could constitute a valuable line of inquiry for the future development of devices adapted to elderly people. PMID- 27713115 TI - A comprehensive transcriptomic analysis of differentiating embryonic stem cells in response to the overexpression of Mesogenin 1. AB - The mutation of somitogenesis protein Mesogenin 1 (Msgn1) has been widely used to study the direct link between somitogenesis and the development of an embryo. Several studies have used gene expression profiling of somitogenesis to identify the key genes in the process, but few have focused on the pathways involved and the coexpression patterns of associated pathways. Here we employed time-course microarray datasets of differentiating embryonic stem cells by overexpressing the transcription factor Msgn1 from the public database library of Gene Expression Omnibus (GEO). Then we applied gene set enrichment analysis (GSEA) to the datasets and performed candidate transcription factors selection. As a result, several significantly regulated pathways and transcription factors (TFs), as well as some of the specific signaling pathways, were identified during somitogenesis under Msgn1 overexpression, most of which had not been reported previously. Finally, significant core genes such as Hes1 and Notch1 as well as some of the TFs such as PPARs and FOXs were identified to construct coexpression networks of related pathways, the expression patterns of which had been validated by our following quantitative real-time PCR (qRT-PCR). The results of our study may help us better understand the molecular mechanisms of somitogenesis in mice at the genome-wide level. PMID- 27713116 TI - Prostate-specific membrane antigen (PSMA) assembles a macromolecular complex regulating growth and survival of prostate cancer cells "in vitro" and correlating with progression "in vivo". AB - The expression of Prostate Specific-Membrane Antigen (PSMA) increases in high grade prostate carcinoma envisaging a role in growth and progression. We show here that clustering PSMA at LNCaP or PC3-PSMA cell membrane activates AKT and MAPK pathways thus promoting proliferation and survival. PSMA activity was dependent on the assembly of a macromolecular complex including filamin A, beta1 integrin, p130CAS, c-Src and EGFR. Within this complex beta1 integrin became activated thereby inducing a c-Src-dependent EGFR phosphorylation at Y1086 and Y1173 EGF-independent residues. Silencing or blocking experiments with drugs demonstrated that all the complex components were required for full PSMA dependent promotion of cell growth and/or survival in 3D culture, but that p130CAS and EGFR exerted a major role. All PSMA complex components were found assembled in multiple samples of two high-grade prostate carcinomas and associated with EGFR phosphorylation at Y1086. The expression of p130CAS and pEGFRY1086 was thus analysed by tissue micro array in 16 castration-resistant prostate carcinomas selected from 309 carcinomas and stratified from GS 3+4 to GS 5+5. Patients with Gleason Score <=5 resulted negative whereas those with GS>=5 expressed p130CAS and pEGFRY1086 in 75% and 60% of the cases, respectively.Collectively, our results demonstrate for the first time that PSMA recruits a functionally active complex which is present in high-grade patients. In addition, two components of this complex, p130CAS and the novel pEGFRY1086, correlate with progression in castration-resistant patients and could be therefore useful in therapeutic or surveillance strategies of these patients. PMID- 27713117 TI - New combined microRNA and protein plasmatic biomarker panel for pancreatic cancer. AB - INTRODUCTION: Lack of diagnostic makers results in loss of operation opportunity in that most patients are diagnosed at the late stage. Pancreatic cancer (PC) has been regarded as a fatal disease with a 5-year survival rate below 10%. Therefore, the development of diagnostic biomarkers for PC is in urgent need to control the mortality of the disease. MATERIALS AND METHODS: This is a case control study including 640 plasma samples from healthy controls (HC), patients with benign pancreatic diseases (BPD), patients with PC; and patients with other gastrointestinal (GI) cancers. Eight biomarker candidates, including miR-20a, miR 21, miR-25, miR-155, miR-196a, miR-210, Macrophage Inhibitory Cytokine-1(MIC-1) and CA19-9, were evaluated to establish two diagnostic indexes in this study. RESULTS: The plasma level of the six miRNAs and MIC-1, CA19-9 were elevated in PC patients compared with those of healthy controls (P<0.001). Among them, miR-20a, miR-21, miR-25, MIC-1 and CA19-9 could distinguish PC patients from those with other GI cancers or BPD. With multivariable logistic regression, we established two specific indexes for diagnosis of PC(Index1 contains miR-21, MIC-1 and CA19 9; Index2 contains miR-25, MIC-1 and CA19-9). In a randomized setting of 260 HC, 168 PC, 132 other GI cancers and 80 BPD patients, both indexes performed not only better sensitivity for PC but also better specificity to distinguish PC from other GI cancers than CA19-9 and individual biomarkers. CONCLUSIONS: These results indicated that combination of biomarkers as a panel could improve diagnostic values compared with using a single marker. Such panels as illustrated in this study could provide novel plasmatic biomarker for PC diagnosis. PMID- 27713118 TI - Exploring the interactions of the RAS family in the human protein network and their potential implications in RAS-directed therapies. AB - RAS proteins are the founding members of the RAS superfamily of GTPases. They are involved in key signaling pathways regulating essential cellular functions such as cell growth and differentiation. As a result, their deregulation by inactivating mutations often results in aberrant cell proliferation and cancer. With the exception of the relatively well-known KRAS, HRAS and NRAS proteins, little is known about how the interactions of the other RAS human paralogs affect cancer evolution and response to treatment. In this study we performed a comprehensive analysis of the relationship between the phylogeny of RAS proteins and their location in the protein interaction network. This analysis was integrated with the structural analysis of conserved positions in available 3D structures of RAS complexes. Our results show that many RAS proteins with divergent sequences are found close together in the human interactome. We found specific conserved amino acid positions in this group that map to the binding sites of RAS with many of their signaling effectors, suggesting that these pairs could share interacting partners. These results underscore the potential relevance of cross-talking in the RAS signaling network, which should be taken into account when considering the inhibitory activity of drugs targeting specific RAS oncoproteins. This study broadens our understanding of the human RAS signaling network and stresses the importance of considering its potential cross talk in future therapies. PMID- 27713119 TI - Concurrent MEK targeted therapy prevents MAPK pathway reactivation during BRAFV600E targeted inhibition in a novel syngeneic murine glioma model. AB - Inhibitors of BRAFV600E kinase are currently under investigations in preclinical and clinical studies involving BRAFV600E glioma. Studies demonstrated clinical response to such individualized therapy in the majority of patients whereas in some patients tumors continue to grow despite treatment. To study resistance mechanisms, which include feedback activation of mitogen-activated protein kinase (MAPK) signaling in melanoma, we developed a luciferase-modified cell line (2341luc) from a BrafV600E mutant and Cdkn2a- deficient murine high-grade glioma, and analyzed its molecular responses to BRAFV600E- and MAPK kinase (MEK)-targeted inhibition. Immunocompetent, syngeneic FVB/N mice with intracranial grafts of 2341luc were tested for effects of BRAFV600E and MEK inhibitor treatments, with bioluminescence imaging up to 14-days after start of treatment and survival analysis as primary indicators of inhibitor activity. Intracranial injected tumor cells consistently generated high-grade glioma-like tumors in syngeneic mice. Intraperitoneal daily delivery of BRAFV600E inhibitor dabrafenib only transiently suppressed MAPK signaling, and rather increased Akt signaling and failed to extend survival for mice with intracranial 2341luc tumor. MEK inhibitor trametinib delivered by oral gavage daily suppressed MAPK pathway more effectively and had a more durable anti-growth effect than dabrafenib as well as a significant survival benefit. Compared with either agent alone, combined BRAFV600E and MEK inhibitor treatment was more effective in reducing tumor growth and extending animal subject survival, as corresponding to sustained MAPK pathway inhibition. Results derived from the 2341luc engraftment model application have clinical implications for the management of BRAFV600E glioma. PMID- 27713120 TI - Automated analysis of acute myeloid leukemia minimal residual disease using a support vector machine. AB - We investigated the ability of support vector machines (SVM) to analyze minimal residual disease (MRD) in flow cytometry data from patients with acute myeloid leukemia (AML) automatically, objectively and standardly. The initial disease data and MRD review data in the form of 159 flow cytometry standard 3.0 files from 36 CD7-positive AML patients in whom MRD was detected more than once were exported. SVM was used for training with setting the initial disease data to 1 as the flag and setting 15 healthy persons to set 0 as the flag. Based on the two training groups, parameters were optimized, and a predictive model was built to analyze MRD data from each patient. The automated analysis results from the SVM model were compared to those obtained through conventional analysis to determine reliability. Automated analysis results based on the model did not differ from and were correlated with results obtained through conventional analysis (correlation coefficient c = 0.986, P > 0.05). Thus the SVM model could potentially be used to analyze flow cytometry-based AML MRD data automatically, objectively, and in a standardized manner. PMID- 27713121 TI - MicroRNA-130a alleviates human coronary artery endothelial cell injury and inflammatory responses by targeting PTEN via activating PI3K/Akt/eNOS signaling pathway. AB - Our study aims to investigate the roles of microRNA-130a (miR-130a) in human coronary artery endothelial cells (HCAECs) injury and inflammatory responses by targeting PTEN through the PI3K/Akt/eNOS signaling pathway. HCAECs were treated with 1.0 mmol/L homocysteine (HCY) and assigned into eight groups: the blank group, the negative control (NC) group, the miR-130a mimics group, the miR-130a inhibitors group, the si-PTEN group, the Wortmannin group, the miR-130a inhibitors + si-PTEN group and the miR-130a mimics + Wortmannin group. Luciferase reporter gene assay was used to validate the relationship between miR-130a and PTEN. The expressions of miR-130a, PTEN and PI3K/Akt/eNOS signaling pathway related proteins were detected by qRT-PCR assay and Western blotting. MTT assay and Hoechst 33258 staining were adopted to testify cell growth and apoptosis. The NO kit assay was used to detect the NO release. ELISA was conducted to measure serum cytokine levels. Luciferase reporter gene assay confirmed the target relationship between miR-130a and PTEN. Compared with the blank and NC groups, the miR-130a mimics and si-PTEN groups showed significant increases in the expressions of PI3K/Akt/eNOS signaling pathway-related proteins, cell viability and the NO release, while serum cytokine levels and cell apoptosis were decreased; by contrast, an opposite trend was observed in miR-130a inhibitors and Wortmannin groups. However, no significant difference was found in the miR-130a inhibitors + si-PTEN and miR-130a mimics + Wortmannin groups when compared with the blank group. These results indicate that miR-130a could alleviate HCAECs injury and inflammatory responses by down-regulating PTEN and activating PI3K/Akt/eNOS signaling pathway. PMID- 27713122 TI - Depletion of pro-oncogenic RUNX2 enhances gemcitabine (GEM) sensitivity of p53 mutated pancreatic cancer Panc-1 cells through the induction of pro-apoptotic TAp63. AB - Recently, we have described that siRNA-mediated silencing of runt-related transcription factor 2 (RUNX2) improves anti-cancer drug gemcitabine (GEM) sensitivity of p53-deficient human pancreatic cancer AsPC-1 cells through the augmentation of p53 family TAp63-dependent cell death pathway. In this manuscript, we have extended our study to p53-mutated human pancreatic cancer Panc-1 cells. According to our present results, knockdown of mutant p53 alone had a marginal effect on GEM-mediated cell death of Panc-1 cells. We then sought to deplete RUNX2 using siRNA in Panc-1 cells and examined its effect on GEM sensitivity. Under our experimental conditions, RUNX2 knockdown caused a significant enhancement of GEM sensitivity of Panc-1 cells. Notably, GEM-mediated induction of TAp63 but not of TAp73 was further stimulated in RUNX2-depleted Panc 1 cells, indicating that, like AsPC-1 cells, TAp63 might play a pivotal role in the regulation of GEM sensitivity of Panc-1 cells. Consistent with this notion, forced expression of TAp63alpha in Panc-1 cells promoted cell cycle arrest and/or cell death, and massively increased luciferase activities driven by TAp63-target gene promoters such as p21WAF1 and NOXA. In addition, immunoprecipitation experiments indicated that RUNX2 forms a complex with TAp63 in Panc-1 cells. Taken together, our current observations strongly suggest that depletion of RUNX2 enhances the cytotoxic effect of GEM on p53-mutated Panc-1 cells through the stimulation of TAp63-dependent cell death pathway even in the presence of a large amount of pro-oncogenic mutant p53, and might provide an attractive strategy to treat pancreatic cancer patients with p53 mutations. PMID- 27713123 TI - Abnormal amphiregulin expression correlates with gastric cancer prognosis. AB - Gastric cancer (GC) is a global health issue with a high mortality rate. Early diagnosis and tracking of GC is a challenge due to a lack of reliable tools. Amphiregulin (AREG) is a member of the epidermal growth factor (EGF) family that activates growth signaling upon binding of EGF receptors. Elevated AREG expression is associated with various pathological conditions, including cancer. Here, we investigated whether increased AREG expression is a disease indicator and/or prognostic biomarker for GC. We used tissue microarray and quantitative real-time polymerase chain reaction to assess AREG expression in clinical tissue specimens at various stages of GC and a conducted bioinformatics analysis to evaluate the value of AREG over-expression as a GC biomarker. We found that both mRNA and protein expression of AREG were increased in the tissues of GC patients when compared to tissues from non-cancer patients or normal tissues. High expression of AREG was also associated with GC clinicopathological characteristics and poor survival. Thus, over-expression of AREG could serve as a novel GC biomarker, and active surveillance of its expression could be a novel approach to GC diagnosis and monitoring. PMID- 27713125 TI - Secondary malignancies after partial versus whole breast irradiation: a systematic review and meta-analysis. AB - Secondary malignancies are a common complication for patients receiving radiotherapy. Here, we compared rates of secondary malignancies after partial breast irradiation (PBI) and whole breast irradiation (WBI). The MEDLINE, EMBASE, and the Cochrane Library databases were systematically searched to identify relevant randomized clinical trials comparing PBI with WBI in breast cancer patients treated with breast-conserving therapy. Four studies including 2,185 patients were selected. Compared to WBI, the pooled odds ratios (OR) for contralateral breast cancer were 0.86 (95% confidence interval (CI) 0.31-2.42; p = 0.78) after 5 years and 1.15 (95% CI 0.43-3.09; p = 0.78) after 10 years for PBI. The pooled ORs for secondary non-breast cancer were 0.91 (95% CI 0.49-1.67; p = 0.77) after 5 years and 1.20 (95% CI 0.39-3.66; p = 0.75) after 10 years for PBI compared to WBI. These results demonstrate that the risk of secondary malignancies is similar for PBI and WBI after breast-conserving radiotherapy. PMID- 27713124 TI - Neutrophilia in locally advanced cervical cancer: A novel biomarker for image guided adaptive brachytherapy? AB - OBJECTIVE: To study the prognostic value of leucocyte disorders in a prospective cohort of cervical cancer patients receiving definitive chemoradiation plus image guided adaptive brachytherapy (IGABT). RESULTS: 113 patients were identified. All patients received a pelvic irradiation concomitant with chemotherapy, extended to the para-aortic area in 13 patients with IVB disease. Neutrophilia and leukocytosis were significant univariate prognostic factors for poorer local failure-free survival (p = 0.000 and p = 0.002, respectively), associated with tumor size, high-risk clinical target volume (HR-CTV) and anemia. No effect was shown for distant metastases but leukocytosis and neutrophila were both poor prognostic factors for in-field relapses (p = 0.003 and p < 0.001). In multivariate analysis, HR-CTV volume (p = 0.026) and neutrophils count > 7,500/MUl (p = 0.018) were independent factors for poorer survival without local failure, with hazard ratio (HR) of 3.1. MATERIALS AND METHODS: We examined patients treated in our Institution between April 2009 and July 2015 by concurrent chemoradiation (45 Gy in 25 fractions +/- lymph node boosts) followed by a magnetic resonance imaging (MRI)-guided adaptive pulse-dose rate brachytherapy (15 Gy to the intermediate-risk clinical target volume). The prognostic value of pretreatment leucocyte disorders was examined. Leukocytosis and neutrophilia were defined as a leukocyte count or a neutrophils count exceeding 10,000 and 7,500/MUl, respectively. CONCLUSIONS: Neutrophilia is a significant prognostic factor for local relapse in locally advanced cervical cancer treated with MRI-based IGABT. This biomarker could help identifying patients with higher risk of local relapse and requiring dose escalation. PMID- 27713126 TI - 18beta-glycyrrhetinic acid suppresses gastric cancer by activation of miR-149-3p Wnt-1 signaling. AB - 18beta-glycyrrhetinic acid (GRA) exerts anti-tumor effects on various types of cancer. In the present study, we found that GRA attenuated the severity of gastritis and suppressed gastric tumorigenesis in transgenic mice. We also discovered that miR-149-3p was downregulated in gastric cancer tissues and cell lines as compared to normal gastric tissues and epithelial cells, but was upregulated by GRA. miR-149-3p expression also correlated negatively with lymphnode metastasis. Our functional assays showed that miR-149-3p overexpression inhibited cell proliferation and cell cycle progression while inducing apoptosis, while inhibition of miR-149-3p had the opposite effects. In addition, we identified Wnt-1 as a direct target of miR-149-3p. These data suggest that GRA inhibits the initiation and progression of gastric tumors by ameliorating the inflammatory microenvironment through downregulation of COX-2 expression and by inhibiting Wnt-1 expression through the upregulation of tumor suppressor miR-149 3p. GRA may thus have the potential to serve as a useful therapeutic agent for the prevention and treatment of gastric cancer. PMID- 27713127 TI - Induction treatments for acute promyelocytic leukemia: a network meta-analysis. AB - BACKGROUND: 9 treatments for acute promyelocytic leukemia (APL) have been compared in many randomized controlled trials (RCT). The conclusions have been inconsistent and the purpose of this study is to conduct a network meta-analysis. RESULTS: Rankings of event-free survival are ATRA+RIF (81.2%), ATRA+ATO (69.6%), ATO (50.6%). Rankings of complete remission are ATRA+RIF (79.3%), ATRA+ATO (64.8%), RIF (60.3%), ATO (55.9%). Rankings of avoiding differentiation syndromes are CT (84.3%), ATO (80.3%), RIF (71.6%), ATRA+RIF (49%), ATRA+ATO (40.8%). METHODS: A total of 1,666 patients from 12 RCTs were enrolled. The frequentist method was used. Relative risks with 95% confidence intervals were calculated. We produced a network plot, a contribution plot, and a forest plot predictive intervals. The inconsistency factor, the surface under the cumulative ranking curve and the publication bias were evaluated. CONCLUSIONS: ATRA+ATO is eligible to be the first-line treatment for APL. ATRA+RIF is a prospective alternative to the first-line treatment. RIF or ATO should be reconsidered as another option for de novo APL. PMID- 27713128 TI - Spc24 is required for meiotic kinetochore-microtubule attachment and production of euploid eggs. AB - Mammalian oocytes are particularly error prone in chromosome segregation during two successive meiotic divisions. The proper kinetochore-microtubule attachment is a prerequisite for faithful chromosome segregation during meiosis. Here, we report that Spc24 localizes at the kinetochores during mouse oocyte meiosis. Depletion of Spc24 using specific siRNA injection caused defective kinetochore microtubule attachments and chromosome misalignment, and accelerated the first meiosis by abrogating the kinetochore recruitment of spindle assembly checkpoint protein Mad2, leading to a high incidence of aneuploidy. Thus, Spc24 plays an important role in genomic stability maintenance during oocyte meiotic maturation. PMID- 27713130 TI - Increased gene expression noise in human cancers is correlated with low p53 and immune activities as well as late stage cancer. AB - Gene expression in metazoans is delicately organized. As genetic information transmits from DNA to RNA and protein, expression noise is inevitably generated. Recent studies begin to unveil the mechanisms of gene expression noise control, but the changes of gene expression precision in pathologic conditions like cancers are unknown. Here we analyzed the transcriptomic data of human breast, liver, lung and colon cancers, and found that the expression noise of more than 74.9% genes was increased in cancer tissues as compared to adjacent normal tissues. This suggested that gene expression precision controlling collapsed during cancer development. A set of 269 genes with noise increased more than 2 fold were identified across different cancer types. These genes were involved in cell adhesion, catalytic and metabolic functions, implying the vulnerability of deregulation of these processes in cancers. We also observed a tendency of increased expression noise in patients with low p53 and immune activity in breast, liver and lung caners but not in colon cancers, which indicated the contributions of p53 signaling and host immune surveillance to gene expression noise in cancers. Moreover, more than 53.7% genes had increased noise in patients with late stage than early stage cancers, suggesting that gene expression precision was associated with cancer outcome. Together, these results provided genomic scale explorations of gene expression noise control in human cancers. PMID- 27713129 TI - New strategy to rescue the inhibition of osteogenesis of human bone marrow derived mesenchymal stem cells under oxidative stress: combination of vitamin C and graphene foams. AB - To rescue the oxidative stress induced inhibition of osteogenesis, vitamin C (VC) was chemically modified onto three-dimensional graphene foams (3D GFs), then their regulation on osteogenesis of human bone marrow-derived mesenchymal stem cells (BM-MSCs) was studied. Combined action of VC + GF significantly decreased H2O2-induced oxidative stress, and rescued H2O2-inhibited cell viability, differentiation and osteogenesis of BM-MSCs in vitro. Further studies revealed that Wnt pathway may be involved in this protection of osteogenesis. Furthermore, an in vivo mouse model of BM-MSCs transplantation showed that VC + GF remarkably rescued oxidative stress inhibited calcium content and bone formation. The combination of VC and GF exhibited more pronounced protective effects against oxidative stress induced inhibition of osteogenesis, compared to monotherapy of VC or GF. Our study proposed a new strategy in stem cell-based therapies for treating bone diseases. PMID- 27713131 TI - Discovery of cell surface vimentin targeting mAb for direct disruption of GBM tumor initiating cells. AB - Intracellular vimentin overexpression has been associated with epithelial mesenchymal transition, metastasis, invasion, and proliferation, but cell surface vimentin (CSV) is less understood. Furthermore, it remains unknown whether CSV can serve as a therapeutic target in CSV-expressing tumor cells. We found that CSV was present on glioblastoma multiforme (GBM) cancer stem cells and that CSV expression was associated with spheroid formation in those cells. A newly developed monoclonal antibody against CSV, 86C, specifically and significantly induced apoptosis and inhibited spheroid formation in GBM cells in vitro. The addition of 86C to GBM cells in vitro also led to rapid internalization of vimentin and decreased GBM cell viability. These findings were associated with an increase in caspase-3 activity, indicating activation of apoptosis. Finally, treatment with 86C inhibited GBM progression in vivo. In conclusion, CSV expressing GBM cells have properties of tumor initiating cells, and targeting CSV with the monoclonal antibody 86C is a promising approach in the treatment of GBM. PMID- 27713132 TI - Highly elevated serum lactate dehydrogenase is associated with central nervous system relapse in patients with diffuse large B-cell lymphoma: Results of a multicenter prospective cohort study. AB - Central nervous system involvement remains a challenging issue in the treatment of patients with diffuse large B-cell lymphoma. We conducted a prospective cohort study with newly diagnosed diffuse large B-cell lymphoma patients receiving rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone to identify incidence and risk factors for central nervous system involvement. Among 595 patients, 279 patients received pre-treatment central nervous system evaluation, and 14 patients had central nervous system involvement at diagnosis (2.3% out of entire patients and 5.0% out of the 279 patients). For those patients, median follow-up duration was 38.2 months and some of them achieved long-term survival. Out of 581 patients who did not have central nervous system involvement at diagnosis, 26 patients underwent secondary central nervous system relapse with a median follow-up of 35 months, and the median time to central nervous system involvement was 10.4 months (range: 3.4-29.2). Serum lactate dehydrogenase > *3 upper limit of normal range, the Eastern Cooperative Oncology Group performance status >= 2, and involvement of sinonasal tract or testis, were independent risk factors for central nervous system relapse in multivariate analysis. Our study suggests that enhanced stratification of serum lactate dehydrogenase according to the National Comprehensive Cancer Network-International Prognostic Index may contribute to better prediction for central nervous system relapse in patients with diffuse large B-cell lymphoma. This trial was registered at clinicaltrials.gov identifier: 01202448. PMID- 27713133 TI - Long non-coding RNAs in anti-cancer drug resistance. AB - Chemotherapy is one of the basic treatments for cancers; however, drug resistance is mainly responsible for the failure of clinical treatment. The mechanism of drug resistance is complicated because of interaction among various factors including drug efflux, DNA damage repair, apoptosis and targets mutation. Long non-coding RNAs (lncRNAs) have been a focus of research in the field of bioscience, and the latest studies have revealed that lncRNAs play essential roles in drug resistance in breast cancer, gastric cancer and lung cancer, et al. Dysregulation of multiple targets and pathways by lncRNAs results in the occurrence of chemoresistance. In this review, we will discuss the mechanisms underlying lncRNA-mediated resistance to chemotherapy and the therapeutic potential of lncRNAs in future cancer treatment. PMID- 27713135 TI - Recombinant heat shock protein 70 functional peptide and alpha-fetoprotein epitope peptide vaccine elicits specific anti-tumor immunity. AB - Alpha-fetoprotein (AFP) is a marker of hepatocellular carcinoma (HCC) and serves as a target for immunotherapy. However, current treatments targeting AFP are not reproducible and do not provide complete protection against cancer. This issue may be solved by developing novel therapeutic vaccines with enhanced immunogenicity that could effectively target AFP-expressing tumors. In this study, we report construction of a therapeutic peptide vaccine by linking heat shock protein 70 (HSP70) functional peptide to the AFP epitope to obtain HSP70 P/AFP-P. This novel peptide was administered into BALB/c mice to observe the effects. Quantification of AFP-specific CD8 + T cells that secrete IFN-gamma in these mice via ELISPOT revealed the synergistic effects of HSP70-P/AFP-P with increased numbers of AFP-specific CD8 + T cells. Similarly, ELISA analysis showed increased granzyme B and perforin released by natural killer cells. Moreover, in vitro cytotoxic T-lymphocyte assays and in vivo tumor preventive experiments clearly showed the higher antitumor effects of HSP70-P/AFP-P against AFP expressing tumors. These results show that treatment of BALB/c mice with HSP70 P/AFP-P induced stronger T-cells responses and improved protective immunity. Our data suggest that HSP70-P/AFP-P may be used as a therapeutic approach in the treatment of AFP-expressing cancers. PMID- 27713134 TI - A three ion channel genes-based signature predicts prognosis of primary glioblastoma patients and reveals a chemotherapy sensitive subtype. AB - Increasing evidence suggests that ion channels not only regulate electric signaling in excitable cells but also play important roles in the development of brain tumor. However, the roles of ion channels in glioma remain controversial. In the present study, we systematically analyzed the expression patterns of ion channel genes in a cohort of Chinese patients with glioma using RNAseq expression profiling. First, a molecular signature comprising three ion channel genes (KCNN4, KCNB1 and KCNJ10) was identified using Univariate Cox regression and two tailed student's t test conducted in overall survival (OS) and gene expression. We assigned a risk score based on three ion channel genes to each primary Glioblastoma multiforme (pGBM) patient. We demonstrated that pGBM patients who had a high risk of unfavorable outcome were sensitive to chemotherapy. Next, we screened the three ion genes-based signature in different molecular glioma subtypes. The signature showed a Mesenchymal subtype and wild-type IDH1 preference. Gene ontology (GO) analysis for the functional annotation of the signature showed that patients with high-risk scores tended to exhibit the increased expression of proteins associated with apoptosis, immune response, cell adhesion and motion and vasculature development. Gene Set Enrichment Analysis (GSEA) results showed that pathways associated with negative regulation of programmed cell death, cell proliferation and locomotory behavior were highly expressed in the high-risk group. These results suggest that ion channel gene expression could improve the subtype classification in gliomas at the molecular level. The findings in the present study have been validated in two independent cohorts. PMID- 27713137 TI - A long noncoding RNA positively regulates CD56 in human natural killer cells. AB - Natural killer (NK) cells are innate immune lymphocytes that play critical roles in host defense against viral infection and surveillance against malignant transformation. Long noncoding RNAs (lncRNAs) are important immune system regulators. Here, we analyzed human primary lymphocyte lncRNA expression profiles to identify NK-lncRNA signatures. We detected numerous novel NK-specific lncRNAs with potential roles in regulating human NK cell differentiation and function. Expression of lnc-CD56, an NK-specific lncRNA, was positively correlated with that of CD56, a classical human NK cell surface marker. We showed that lnc-CD56 may function as a positive regulator of CD56 in primary human NK cells and differentiated NK cells from human CD34+ hematopoietic progenitor cells. Our data provide an annotated human NK cell lncRNA expression catalog and demonstrate a key role for lncRNAs in NK cell biology. PMID- 27713138 TI - Transgenic and gene knockout mice in gastric cancer research. AB - Mouse models are useful tool for carcinogenic study. They will greatly enrich the understanding of pathogenesis and molecular mechanisms for gastric cancer. However, only few of mice could develop gastric cancer spontaneously. With the development and improvement of gene transfer technology, investigators created a variety of transgenic and knockout/knockin mouse models of gastric cancer, such as INS-GAS mice and gastrin knockout mice. Combined with helicobacter infection and carcinogens treatment, these transgenic/knockout/knockin mice developed precancerous or cancerous lesions, which are proper for gene function study or experimental therapy. Here we review the progression of genetically engineered mouse models on gastric cancer research, and emphasize the effects of chemical carcinogens or infectious factors on carcinogenesis of genetically modified mouse. We also emphasize the histological examination on mouse stomach. We expect to provide researchers with some inspirations on this field. PMID- 27713139 TI - Hypomethylation of HLA-DRB1 and its clinical significance in psoriasis. AB - Increasing evidences indicate that the abnormal DNA methylation is involved in the pathogenesis of psoriasis. A number of SNPs in HLA-DRB1 have been found being associated with the risk of psoriasis, however it is unclear that metylation status within HLA-DRB1 in psoriasis. Here, DNA and RNA were obtained from epidermis of 56 patients with plaque psoriasis and 28 healthy volunteers served as the control group. For the first time, we discovered mean methylation rate for HLA-DRB1 is 52.2%, 64.3% and 68.1% in epidermis from psoriatic lesions, psoriatic non-lesions and healthy controls, respectively. HLA-DRB1 methylation in psoriatic lesions is significantly lower than in psoriatic non-lesions (t = 13.077, p < 0.001). However, there is no significant difference for HLA-DRB1 methylation between in psoriatic non-lesions and in healthy controls (t = 1.046, p = 0.299). HLA-DRB1 methylation in psoriatic lesions is negatively correlated to PASI score (r = -0.431, p = 0.001). HLA-DRB1 methylation in psoriatic lesions of the patients with onset age<=18 years is significantly lower than the other patients (t = 3.968, p < 0.001). Meanwhile, HLA-DRB1 mRNA expression is significantly increased in psoriatic lesions comparing to psoriatic non-lesions (t = 12.119, p < 0.001). There are no significant difference for HLA-DRB1 mRNA expression between in psoriatic non-lesions and in healthy controls (t = 1.172, p = 0,245). Moreover, HLA-DRB1 mRNA expression is negatively associated with HLA-DRB1 methylation in psoriatic lesions (r = 0.932, p < 0.001). In conclusions, our results showed hypomethylation of HLA-DRB1 is associated with HLA-DRB1 mRNA expression and severity of the disease, indicating that hypomethylation of HLA DRB1 may play roles in the pathogenesis of psoriasis. PMID- 27713136 TI - The role of extracellular vesicles in mediating progression, metastasis and potential treatment of hepatocellular carcinoma. AB - Hepatocellular carcinoma (HCC) is a major cause of cancer-related death worldwide. As vectors for intercellular information exchange, the potential role of extracellular vesicles (EVs) in HCC formation, progression and therapy has been widely investigated. In this review, we explore the current status of the researches in this field. Altogether there is undeniable evidence that EVs play a crucial role in HCC development, metastasis. Moreover, EVs have shown great potential as drug delivery systems (DDSs) for the treatment of HCC. Exosomal miRNAs derived from HCC cells can enhance transformed cell growth in recipient cells by modulating the expression of transforming growth factor-beta activated kinase-1(TAK1) and downstream signaling molecules. Furthermore, vacuolar protein sortin 4 homolog A(VPS4A) and insulin-like growth factor(IGF)-1 regulate exosome mediated miRNAs transfer. Immune cells- derived EVs containing integrin alphaMbeta2 or CD147 may facilitate HCC metastasis. In addition, EVs-mediated shuttle of long non-coding RNAs (lncRNAs), specifically linc- VLDLR and linc-ROR promote chemoresistance of malignant cells. Heat shock proteins (HSPs)-harboring exosomes derived from HCC tumor cells increase the antitumor effect of natural killer (NK) cells, thus enhancing HCC immunotherapy. Indeed, inhibition of HCC tumor growth has been associated with tumor cell-derived exosomes (TEX)-pulsed dentritic cells (DCs). Exosomes are also essential in liver metastasis during colorectal carcinoma (CRC) and pancreatic ductal adenocarcinomas (PDAC). Therefore, as nucleic acid and drug delivery vehicles, EVs show a tremendous potential for effective treatment against HCC. PMID- 27713140 TI - Neuroprotective effects of CD4+CD25+Foxp3+ regulatory T cells in a 3xTg-AD Alzheimer's disease model. AB - Alzheimer's disease patients display neuropathological lesions, including the accumulation of amyloid-beta (Abeta) peptide and neurofibrillary tangles. Although the mechanisms causing the neurodegenerative process are largely unknown, increasing evidence highlights a critical role of immunity in the pathogenesis of Alzheimer's disease. In the present study, we investigated the role of regulatory T cells (Tregs) on Alzheimer's disease progression. First, we explored the effect of Tregs (CD4+CD25+ T cells) and Teffs (CD4+CD25- T cells) in an adoptive transfer model. Systemic transplantation of purified Tregs into 3xTg AD mice improved cognitive function and reduced deposition of Abeta plaques. In contrast, adoptive transfer of Teffs diminished behavioral function and cytokine production. Next, we transiently depleted Treg population using an anti-CD25 antibody (PC61). Depletion of Tregs for four months resulted in a marked aggravation of the spatial learning deficits of six-month-old 3xTg-AD mice. Additionally, it resulted in decreasing glucose metabolism, as assessed by positron emission tomography (PET) with 18F-2 fluoro-2-deoxy-D-glucose ([F-18] FDG) neuroimaging. Importantly, the deposition of Abeta plaques and microglia/macrophage was increased in the hippocampal CA1 and CA3 regions of the Treg depleted 3xTg-AD compared to the vehicle-treated 3xTg-AD group. Our finding suggested that systemic Treg administration ameliorates disease progression and could be an effective Alzheimer's disease treatment. PMID- 27713141 TI - Fibroblast growth factor 23 dysregulates late sodium current and calcium homeostasis with enhanced arrhythmogenesis in pulmonary vein cardiomyocytes. AB - Fibroblast growth factor 23 (FGF23), elevated in chronic renal failure, increases atrial arrhythmogenesis and dysregulates calcium homeostasis. Late sodium currents (INa-Late) critically induces ectopic activity of pulmoanry vein (the most important atrial fibrillation trigger). This study was to investigate whether FGF23 activates the INa-Late leading to calcium dysregulation and increases PV arrhythmogenesis. Patch clamp, western blot, and confocal microscopy were used to evaluate the electrical activities, calcium homeostasis, and mitochondrial reactive oxygen species (ROS) in PV cardiomyocytes with or without FGF23 (0.1 or 1 ng/mL) incubation for 4~6 h. Compared to the control, FGF23 (1 ng/mL, but not 0.1 ng/mL)-treated PV cardiomyocytes had a faster beating rate. FGF23 (1 ng/mL)-treated PV cardiomyocytes had larger INa-Late, calcium transients, and mitochondrial ROS than controls. However, ranolazine (an inhibitor of INa-Late) attenuated FGF23 (1 ng/mL)-increased beating rates, calcium transients and mitochondrial ROS. FGF23 (1 ng/mL)-treated PV cardiomyocytes exhibited larger phosphorylation of calcium/calmodulin-dependent protein kinase II (CaMKII). Chelerythrine chloride (an inhibitor of protein kinase C) decreased INa-Late in FGF23 (1 ng/mL)-treated PV cardiomyocytes. However, KN93 (a selective CaMKII blocker) decreased INa-Late in control and FGF23 (1 ng/mL)-treated PV cardiomyocytes to a similar extent. In conclusion, FGF23 increased PV arrhythmogenesis through sodium and calcium dysregulation by acting protein kinase C signaling. PMID- 27713142 TI - Novel circulating lipid measurements for current dyslipidemias in non-treated patients undergoing coronary angiography: PCSK9, apoC3 and sdLDL-C. AB - Plasma levels of proprotein convertase subtilisin/kexin type 9 (PCSK9), apolipoprotein C-III (apoC3) and small dense low density lipoprotein cholesterol (sdLDL-C), have been recently recognized as circulating atherosclerosis-related lipid measurements. We aimed to elucidate their associations with current dyslipidemias, and identify their levels at increased risk to dyslipidemia. A total of 1,605 consecutive, non-treated patients undergoing diagnostic/interventional coronary angiography were examined. Plasma PCSK9 and apoC3 levels were determined using a validated ELISA assay, and sdLDL-C was measured by the Lipoprint LDL System. Plasma levels of PCSK9, apoC3, and sdLDL-C were associated with the current dyslipidemias classification (all p<0.001). PCSK9 significantly conferred prediction of both hypercholesterolemia and combined hyperlipidemia at a level of 235 ng/ml; apoC3 levels for hypertriglyceridemia, hypercholesterolemia and combined hyperlipidemia were 80.0, 71.5, and 86.4 MUg/ml, respectively; and sdLDL-C for hypertriglyceridemia, hypercholesterolemia, combined hyperlipidemia and hypo high density lipoprotein (HDL) cholesterolemia 3.5, 2.5, 4.5, and 2.5 mg/dl, respectively (all p<0.001 for area under the receiver-operating characteristic curve). In a polytomous logistic model comparing increasing LDL-C categories, the interactions with high PCSK9, apoC3, and sdLDL-C elevated gradually. Similarly, apoC3 and sdLDL-C showed elevated interaction with increased triglyceride categories, and only sdLDL-C showed interaction with decreased HDL cholesterol (HDL-C) categories. Furthermore, discordances of PCSK9, apoC3, and sdLDL-C with current dyslipidemias were observed. PCSK9, apoC3, and sdLDL-C showed significant interactions with current dyslipidemias, and were predictive in the screening. The substantial discordances with current dyslipidemias might provide novel view in lipid management and further cardiovascular benefit. PMID- 27713143 TI - Signaling through hepatocyte vasopressin receptor 1 protects mouse liver from ischemia-reperfusion injury. AB - : Terlipressin has been used extensively in the management of certain complications associated with end-stage liver diseases (ESLDs). In our pilot study, terlipressin treatment showed beneficial effects on liver function in patients with decompensated cirrhosis, however whether it plays a role in liver ischemia-reperfusion injury (IRI) remains unknown. Using a mouse nonlethal hepatic IR model, we found terlipressin administration significantly ameliorated IR-induced liver apoptosis, necrosis and inflammation. Furthermore, despite its known effect on visceral vasoconstriction, hemodynamic evaluation of murine hepatic tissue after IR revealed no change of overall hepatic blood flow after terlipressin treatment. Further studies identified the upregulation of vasopressin receptor 1 (V1R) expression on hepatocytes upon IR. In isolated hepatocyte hypoxia/reoxygenation model, the active component of terlipressin, lysine vasopressin, conferred hepatocytes resistant to oxidative stress-induced apoptosis. Mechanistic studies revealed the V1R engagement activated the Wnt/beta catenin/FoxO3a/AKT pathway, which subsequently circumvented the proapoptotic events, thus ameliorated hepatocyte apoptosis. Furthermore, genetic knockdown of V1R expression in hepatocyte cell lines or blockade of this signaling pathway abrogated such protective effect. CONCLUSION: These data highlight the functional importance of the hepatocyte V1R/Wnt/beta-catenin/FoxO3a/AKT pathway in protecting liver from oxidative stress-induced injury. PMID- 27713144 TI - RGS6 is an essential tumor suppressor that prevents bladder carcinogenesis by promoting p53 activation and DNMT1 downregulation. AB - Urinary bladder cancer (UBC) is largely caused by exposure to toxic chemicals including those in cigarette smoke (i.e. BBN). An activating SNP in RGS6 is associated with a pronounced reduction in UBC risk, especially among smokers. However, the mechanism underlying this reduction remains unknown. Here we demonstrate that RGS6 is robustly expressed in human urothelium, where urothelial cell carcinoma originates, and is downregulated in human UBC. Utilizing RGS6-/- mice we interrogated a possible role for RGS6 as a tumor suppressor using the BBN induced bladder carcinogenesis model that closely recapitulates human disease. As in humans, RGS6 is robustly expressed in mouse urothelium. RGS6 loss dramatically accelerates BBN-induced bladder carcinogenesis, with RGS6-/- mice consistently displaying more advanced pathological lesions than RGS6+/+ mice. Furthermore, BBN treatment promotes urothelial RGS6 mRNA and protein downregulation. RGS6 loss impairs p53 activation and promotes aberrant accumulation of oncogenic protein DNMT1 in urothelium. Tumor suppressor RASSF1A, a DNMT1-regulated gene, is also silenced, likely via methylation of its promoter during BBN exposure. We hypothesize that this BBN-induced RGS6 loss represents a critical hit in UBC as it irrevocably impairs the anti-proliferative actions of the ATM/p53 and RASSF1A pathways. Consistent with these findings, RGS6-/- mice treated with CP-31398, a p53-stablizing agent, and/or 5-Aza, a DNMT1 inhibitor, are protected from BBN induced tumorigenesis. Together, our data identify RGS6 as a master tumor suppressor modulating two critical signaling pathways that are often dysregulated in UBC; therefore, RGS6 represents a potential novel biomarker for UBC diagnosis/prognosis and an appealing new target in its treatment. PMID- 27713145 TI - Glycodelin is a potential novel follow-up biomarker for malignant pleural mesothelioma. AB - Malignant pleural mesothelioma (MPM) is a rare and aggressive tumor with a short survival time arising from the mesothelial cells of the pleura. Soluble mesothelin-related peptide (SMRP), osteopontin or EFEMP1 (Fibulin-3) are well described biomarkers for malignant mesothelioma with moderate sensitivity and specificity. In this study, we characterized the expression of glycodelin, a marker for risk pregnancy, in MPM by RNA and protein analyses and investigated its potential as a MPM biomarker. We were able to detect glycodelin in the serum of MPM patients. Compared to benign lung diseases, the serum levels were significant increased. Patients with high glycodelin serum levels revealed a worse overall survival. The glycodelin serum levels correlated with the tumor response to treatment. A comparison of SMRP and glycodelin serum measurement in a large patient cohort demonstrated that the detection of both soluble factors can increase the reliable diagnostic of MPM. Glycodelin was highly expressed in MPM tumors. Analyses of a tissue micro array indicated that the immunomodulatory form glycodelin A was expressed in MPM and correlated with the survival of the patients. Altogether, glycodelin seems to be a new potential biomarker for the aggressive malignant pleural mesothelioma. PMID- 27713146 TI - TGF-beta and NF-kappaB signaling pathway crosstalk potentiates corneal epithelial senescence through an RNA stress response. AB - The corneal epithelium plays important roles in the maintenance of corneal transparency for good vision, and acts as a protective barrier against foreign insults. Structural and functional changes with aging in the corneal epithelium have been documented. Here we found that transforming growth factor-beta (TGF beta) is highly expressed in the elderly donor corneal epithelium, as are senescence-associated genes, such as p16 and p21. In human corneal epithelial cell (HCEC) models, TGF-beta induces cellular senescence, characterized by increased SA-beta-gal positive cells and elevated expression of p16 and p21. Pharmacological inhibition of TGF-beta signaling alleviates TGF-beta-induced cellular senescence. In addition, we determined that senescence-associated inflammation was significantly aggravated in TGF-beta-induced cellular senescence by detecting the expression of interleukin-6 (IL-6), IL-8, and tumor necrosis factor alpha (TNFalpha). Both genetic and pharmacological approaches revealed that blocking nuclear factor-kappaB (NF-kappaB) signaling not only inhibited the production of inflammatory factors, but also rescued the senescent phenotype induced by TGF-beta in HCECs. Mechanistically, TGF-beta induced an atypical RNA stress responses, leading to accelerated mRNA degradation of IkappaBalpha, an inhibitor of NF-kappaB. Together, our data indicate that TGF-beta-driven NF kappaB activation contributes to corneal epithelial senescence via RNA metabolism and the inflammation blockade can attenuate TGF-beta-induced senescence. PMID- 27713147 TI - MiR-608, pre-miR-124-1 and pre-miR26a-1 polymorphisms modify susceptibility and recurrence-free survival in surgically resected CRC individuals. AB - Genetic variation within microRNA (miRNA) may result in its abnormal folding or aberrant expression, contributing to colorectal turmorigenesis and metastasis. However, the association of six polymorphisms (miR-608 rs4919510, miR-499a rs3746444, miR-146a rs2910164, pre-miR-143 rs41291957, pre-miR-124-1 rs531564 and pre-miR-26a-1 rs7372209) with colorectal cancer (CRC) risk, therapeutic response and survival remains unclear. A retrospective study was carried out to investigate the association in 1358 0-III stage resected CRC patients and 1079 healthy controls using Sequenom's MassARRAY platform. The results showed that rs4919510 was significantly associated with a decreased susceptibility to CRC in co-dominant, allele and recessive genetic models, and the protective role of rs4919510 allele G and genotype GG was more pronounced among stage 0-II cases; significant association between rs531564 and poor RFS was observed in cases undergoing adjuvant chemo-radiotherapy in co-dominant, allele and dominant models; moreover, there was a positive association between rs7372209 and recurrence-free survival in stage II cases in co-dominant and over-dominant models; additionally, a cumulative effect of rs531564 and rs7372209 at-risk genotypes with hazard ratio at 1.30 and 1.95 for one and two at-risk genotypes was examined in stage II cases, respectively. Our findings indicated that rs4919510 allele G and genotype GG were protective factors for 0-II stage CRC, rs7372209 and rs531564 could decrease RFS in II stage individuals and resected CRC patients receiving adjuvant chemo-radiology. PMID- 27713149 TI - Human beta-defensin 3 contributes to the carcinogenesis of cervical cancer via activation of NF-kappaB signaling. AB - Human beta-defensin 3 (hBD3), an antimicrobial peptide (AMP) expressed in epithelium in response to various stimulations including human papillomavirus infection, has recently been found to be overexpressed in head and neck cancers and exhibit tumorigenic activities. However, the role of hBD3 in cervical cancer remains to be investigated. In this study, we showed by immunohistochemistry that hBD3 expression was elevated in cervical cancer samples of different stages versus the normal tissue, and was positively correlated with the progression of the disease. Overexpression of hBD3 in cervical cancer cell lines promoted cell proliferation by accelerating G1/S progression and enhanced cell migration and invasion in vitro. These oncogenic effects of hBD3 were associated with activation of NF-kappaB signaling. Using a mouse xenograft model, we further demonstrated that hBD3 overexpression promoted the growth of cervical cancer cells in vivo. Our results suggested that hBD3 is involved in the carcinogenesis and development of cervical cancer, and may serve as a biomarker or therapeutic target of this disease. PMID- 27713148 TI - A novel mechanism of action of HER2 targeted immunotherapy is explained by inhibition of NRF2 function in ovarian cancer cells. AB - Nuclear erythroid related factor-2 (NRF2) is known to promote cancer therapeutic detoxification and crosstalk with growth promoting pathways. HER2 receptor tyrosine kinase is frequently overexpressed in cancers leading to uncontrolled receptor activation and signaling. A combination of HER2 targeting monoclonal antibodies shows greater anticancer efficacy than the single targeting antibodies, however, its mechanism of action is largely unclear. Here we report novel actions of anti-HER2 drugs, Trastuzumab and Pertuzumab, involving NRF2.HER2 targeting by antibodies inhibited growth in association with persistent generation of reactive oxygen species (ROS), glutathione (GSH) depletion, reduction in NRF2 levels and inhibition of NRF2 function in ovarian cancer cell lines. The combination of antibodies produced more potent effects than single antibody alone; downregulated NRF2 substrates by repressing the Antioxidant Response (AR) pathway with concomitant transcriptional inhibition of NRF2. We showed the antibody combination produced increased methylation at the NRF2 promoter consistent with repression of NRF2 antioxidant function, as HDAC and methylation inhibitors reversed such produced transcriptional effects. These findings demonstrate a novel mechanism and role for NRF2 in mediating the response of cancer cells to the combination of Trastuzumab and Pertuzumab and reinforce the importance of NRF2 in drug resistance and as a key anticancer target. PMID- 27713150 TI - Second-generation proteasome inhibitor carfilzomib sensitizes neuroblastoma cells to doxorubicin-induced apoptosis. AB - Neuroblastoma (NB), which accounts for about 15% of cancer-related mortality in children, is the most common extracranial malignant neoplasm in children. Elevated level of proteasome activity promotes cancer development and the inhibition of proteasome activity is a promising strategy for cancer treatment. Therefore, targeting proteasome by small molecule inhibitors may be a viable option for NB therapy. Here in this study, we show that a novel proteasome inhibitor Carfilzomib (CFZ) exerts anti-tumor effect on NB. CFZ caused decreased cell viability and attenuated colony formation ability of a subset of NB cell lines. CFZ induced cell apoptosis in NB cells. Moreover, CFZ enhanced the cytotoxic effect of doxorubicin (Dox) on NB cells and Dox-induced p38 and JNK phosphorylation. In addition, CFZ inhibited Dox-induced NF-kappaB activation by stabilizing the protein level of IkappaBalpha. Furthermore, CFZ induced apoptosis and augmented Dox-induced apoptosis in NB tumor cells in orthotopic xenograft mouse models. In summary, our study suggests that proteasome is a therapeutic target in NB and proteasome inhibition by CFZ is a potential therapeutic strategy for treating NB patients. PMID- 27713151 TI - Selinexor, a Selective Inhibitor of Nuclear Export (SINE) compound, acts through NF-kappaB deactivation and combines with proteasome inhibitors to synergistically induce tumor cell death. AB - The nuclear export protein, exportin-1 (XPO1/CRM1), is overexpressed in many cancers and correlates with poor prognosis. Selinexor, a first-in-class Selective Inhibitor of Nuclear Export (SINE) compound, binds covalently to XPO1 and blocks its function. Treatment of cancer cells with selinexor results in nuclear retention of major tumor suppressor proteins and cell cycle regulators, leading to growth arrest and apoptosis. Recently, we described the selection of SINE compound resistant cells and reported elevated expression of inflammation-related genes in these cells. Here, we demonstrated that NF-kappaB transcriptional activity is up-regulated in cells that are naturally resistant or have acquired resistance to SINE compounds. Resistance to SINE compounds was created by knockdown of the cellular NF-kappaB inhibitor, IkappaB-alpha. Combination treatment of selinexor with proteasome inhibitors decreased NF-kappaB activity, sensitized SINE compound resistant cells and showed synergistic cytotoxicity in vitro and in vivo. Furthermore, we showed that selinexor inhibited NF-kappaB activity by blocking phosphorylation of the IkappaB-alpha and the NF-kappaB p65 subunits, protecting IkappaB-alpha from proteasome degradation and trapping IkappaB-alpha in the nucleus to suppress NF-kappaB activity. Therefore, combination treatment of selinexor with a proteasome inhibitor may be beneficial to patients with resistance to either single-agent. PMID- 27713152 TI - Detection of cellular senescence within human invasive breast carcinomas distinguishes different breast tumor subtypes. AB - Oncogene-induced senescence is thought to act as a barrier to tumorigenesis by arresting cells at risk of malignant transformation. Nevertheless, numerous findings suggest that senescent cells may conversely promote tumor progression through the development of the senescence-associated secretome they produce. It is likely that the composition and the physiological consequences mediated by the senescence secretome are dependent on the oncogenes that trigger the senescence program. Breast cancer represents a heterogenous disease that can be divided into breast cancer subtypes due to different subsets of genetic and epigenetic abnormalities. As tumor initiation and progression of these breast cancer subtypes is triggered by diverse oncogenic stimuli, differences in the senescence secretomes within breast tumors might be responsible for tumor initiation, progression, metastasis and therapeutic response. Many studies have addressed the role of senescence as a barrier to tumor progression using murine xenograft models. However, few investigations have been performed to elucidate the degree to which senescent tumor cells are present within untreated human tumors, and if present, whether these senescent tumor cells may play a role in disease progression. In the present study we analysed the appearance of senescent cells within invasive breast cancers. Detection of cellular senescence by the use of SAbeta-galactosidase (SAbeta-gal) staining within invasive breast carcinoms from 129 untreated patients revealed differences in the amount of SAbeta-gal+ tumor cells between breast cancer subtypes. The highest percentages of SAbeta-gal+ tumor cells were found in HER2-positive and luminal A breast carcinomas whereas triple negative tumors showed either little or no positivity. PMID- 27713153 TI - CCND1 mutations increase protein stability and promote ibrutinib resistance in mantle cell lymphoma. AB - Mantle cell lymphoma (MCL) is characterized by the t(11;14) translocation, which leads to deregulated expression of the cell cycle regulatory protein cyclin D1 (CCND1). Genomic studies of MCL have also identified recurrent mutations in the coding region of CCND1. However, the functional consequence of these mutations is not known. Here, we showed that, compared to wild type (WT), single E36K, Y44D or C47S CCND1 mutations increased CCND1 protein levels in MCL cell lines. Mechanistically, these mutations stabilized CCND1 protein through attenuation of threonine-286 phosphorylation, which is important for proteolysis through the ubiquitin-proteasome pathway. In addition, the mutant proteins preferentially localized to the nucleus. Interestingly, forced expression of WT or mutant CCND1 increased resistance of MCL cell lines to ibrutinib, an FDA-approved Bruton tyrosine kinase inhibitor for MCL treatment. The Y44D mutant sustained the resistance to ibrutinib even at supraphysiologic concentrations (5-10 MUM). Furthermore, primary MCL tumors with CCND1 mutations also expressed stable CCND1 protein and were resistant to ibrutinib. These findings uncover a new mechanism that is critical for the regulation of CCND1 protein levels, and is directly relevant to primary ibrutinib resistance in MCL. PMID- 27713155 TI - Chicken GHR natural antisense transcript regulates GHR mRNA in LMH cells. AB - Growth hormone receptor (GHR) played key roles in human and animal growth. Both human laron type dwarfism and sex linked dwarf chicken were caused by the mutation of GHR gene. In this study, we identified an endogenously expressed long non-coding natural antisense transcript, GHR-AS, which overlapped with the GHR mRNA (GHR-S) in a tail to tail manner. Spatial and temporal expression analyses indicated that GHR-AS were highly expressed in chicken liver and displayed ascending with the development of chicken from E10 to 3 w of age. Interfering GHR AS caused GHR-S decreasing, accompanied with increasing of the inactive gene indicator, H3K9me2, in the GHR-S promoter regions in LMH cells. RNase A experiment exhibited that GHR-AS and GHR-S can form double strand RNAs at the last exon of GHR gene in vivo and in vitro, which hinted they could act on each other via the region. In addition, the levels of GHR-S and GHR-AS can be affected by DNA methylation. Compared the normal chicken with the dwarfs, the negative correlation trends were showed between the GHR-S promoter methylation status and the GHR-AS levels. This is the first report of that GHR gene possessed natural antisense transcript and the results presented here further highlight the fine and complicated regulating mechanism of GHR gene in chicken development. PMID- 27713154 TI - NRF2 promotes breast cancer cell proliferation and metastasis by increasing RhoA/ROCK pathway signal transduction. AB - Nuclear factor erythroid 2-related factor (NRF2) is an important transcription factor in oxidative stress regulation. Overexpression of NRF2 is associated with human breast carcinogenesis, and increased NRF2 mRNA levels predict poor patient outcome for breast cancer. However, the mechanisms linking gain of NRF2 expression and poor prognosis in breast cancer are still unclear. Here, we provide evidence that NRF2 deletion inhibits proliferation and metastasis of breast cancer cells by down-regulating RhoA. Restoration of RhoA in MCF7 and MDA MB-231 cells induced NRF2 knockdown-suppressed cell growth and metastasis in vitro, and NRF2 silencing suppressed stress fiber and focal adhesion formation leading to decreased cell migration and invasion. Mechanistic studies showed that NRF2 binds to the promoter region of estrogen-related receptor alpha (ERR1) and may function as a silencer. This may enhance RhoA protein stability and lead to RhoA overexpression in breast cancer cell. Our findings indicate that NRF2 silencing-mediated reduction of RhoA expression contributes, at least in part, to the poor outcome of breast cancer patients with high NRF2 expression. PMID- 27713156 TI - Kindlin-2 interacts with beta-catenin and YB-1 to enhance EGFR transcription during glioma progression. AB - Kindlin-2 promotes carcinogenesis through regulation of cell-cell and cell extracellular matrix adhesion. However, the role of Kindlin-2 in glioma has not been elucidated. We investigated Kindlin-2 expression in 188 human glioma tissue samples. High Kindlin-2 expression was correlated with high pathological grade and a worse prognosis. Kindlin-2 promoted glioma cell motility and proliferation both in vitro and in vivo. Importantly, Kindlin-2 activated the EGFR pathway and increased EGFR mRNA levels. In addition to up-regulating Y-box binding protein-1 (YB-1) and beta-catenin expression, Kindlin-2 formed a transcriptional complex with YB-1 and beta-catenin that bound to the EGFR promoter and enhanced transcription. The beta-catenin/YB-1/EGFR pathway was required for Kindlin-2 mediated functions. Our data provide a better understanding of the mechanisms underlying glioma progression, and suggest that Kindlin-2 may be a biomarker and therapeutic target in glioma. PMID- 27713158 TI - Cancer cell-binding peptide fused Fc domain activates immune effector cells and blocks tumor growth. AB - Therapeutic strategies aiming at mobilizing immune effector cells to kill tumor cells independent of tumor mutational load and MHC expression status are expected to benefit cancer patients. Recently, we engineered various peptide-Fc fusion proteins for directing Fcg receptor-bearing immune cells toward tumor cells. Here, we investigated the immunostimulatory and anti-tumor effects of one of the engineered Fc fusion proteins (WN-Fc). In contrast to the Fc control, soluble WN Fc-1 fusion protein activated innate immune cells (e.g. monocytes, macrophages, dendritic cells, NK cells), resulting in cytokine production and surface display of the lytic granule marker CD107a on NK cells. An engineered Fc-fusion variant carrying two peptide sequences (WN-Fc-2) also activated immune cells and bound to various cancer cell types with high affinity, including the murine 4T1 breast carcinoma cells. When injected into 4T1 tumor-bearing BALB/c mice, both peptide Fc fusions accumulated in tumor tissues as compared to other organs such as the lungs. Moreover, treatment of 4T1 tumor-bearing BALB/c mice by means of two intravenous injections of the WN-Fc fusion proteins inhibited tumor growth with WN-Fc-2 being more effective than WN-Fc-1. Treatment resulted in tumor infiltration by T cells and NK cells. These new engineered WN-Fc fusion proteins may be a promising alternative to existing immunotherapies for cancer. PMID- 27713157 TI - Delayed reendothelialization with rapamycin is rescued by the addition of nicorandil in balloon-injured rat carotid arteries. AB - Rapamycin is an immunosuppressive agent that is added to drug eluting stents. It prevents restenosis, but it also impairs reendothelialization. Nicorandil is a hybrid agent with adenosine triphosphated (ATP)-sensitive K+ (KATP) channel opener and nitrate properties. It prevents oxidative stress and cell apoptosis induced by rapamycin in endothelial cells in vitro. However, whether nicorandil promotes reendothelialization after angioplasty delayed by rapamycin remains to be determined. Balloon injury model was established in SD rats. Nicorandil increased reendothelialization impaired by rapamycin, and it decreased xanthine oxidase (XO)-generated reactive oxygen species (ROS) induced by rapamycin. In addition, eNOS expression inhibited by rapamycin was increased by nicorandil in vivo. In vitro, rapamycin-impeded cardiac microvascular endothelial cells (CMECs) migration, proliferation and rapamycin-induced ROS production were reversed by nicorandil. Knockdown of XO partially inhibited rapamycin-induced ROS production and cell apoptosis in CMECs, and it promoted CMECs migration and proliferation suppressed by rapamycin. Knockdown of Akt partially prevents eNOS upregulation promoted by nicorandil. The beneficial effect of nicorandil is exhibited by inhibiting XO and up-regulating Akt pathway. Nicorandil combined with rapamycin in effect rescue the deficiencies of rapamycin alone in arterial healing after angioplasty. PMID- 27713159 TI - Lipopolysaccharide increases the release of VEGF-C that enhances cell motility and promotes lymphangiogenesis and lymphatic metastasis through the TLR4- NF kappaB/JNK pathways in colorectal cancer. AB - Lipopolysaccharide (LPS) exists in the outer membrane of Gram-negative bacteria. Colorectal normal epithelium and colorectal cancer cells in situ are continuously exposed to LPS from intestinal bacteria, while little is known about the influence of LPS on colorectal cancer progression and metastasis. In this study, we investigated the potential role of LPS on colorectal cancer progression and metastasis as well as the underlying mechanisms. We measured higher LPS concentration in colorectal cancer tissues and even higher LPS concentration in colorectal cancer tissues with lymph node metastasis. LPS significantly enhanced cancer cell motility and promoted human dermal lymphatic endothelial cells' (HDLECs') capacity of tube-like formation in vitro, as well as accelerates lymphangiogenesis and lymph node metastasis in nude mice. Furthermore, we demonstrated LPS notably increased the expression of VEGF-C in a time-dependent and concentration-dependent manner. VEGF-C is a key regulator for lymphangiogenesis and lymph node metastasis. By constructing lentivirus-mediated shVEGF-C cells, VEGF-C down-regulation suppressed LPS' promotive effect on cancer cell motility and HDLEC tube-like formation capacity. In addition, we found TLR4- NF-kappaB/JNK signal pathways were important for LPS to increase VEGF-C expression. All these result suggested a critical role for LPS in migration, invasion, lymphangiogenesis and lymph node metastasis of colorectal cancer, providing evidence that LPS increased VEGF-C secretion to promote cell motility and lymphangiogenesis via TLR4- NF-kappaB/JNK signaling. PMID- 27713161 TI - Role of long noncoding RNA UCA1 as a common molecular marker for lymph node metastasis and prognosis in various cancers: a meta-analysis. AB - Accumulating evidences indicated that UCA1 expression was up-regulated in various cancers, and high UCA1 expression was correlated with metastasis and prognosis. This meta-analysis collected all eligible studies and explored the relationships between UCA1 expression and lymph node metastasis (LNM) or overall survival (OS). Literature collection was performed by using electronic databases PubMed, Cochrane Library, and Web of Science (up to June 13, 2016). According to the inclusion and exclusion criteria, twelve studies were included in the meta analysis. The result showed that high UCA1 expression was correlated with more LNM (OR=2.50, 95 %CI: 1.58-3.96, p<0.0001) in a random-effects model (I2=45 %, p=0.08) and could predict poor OS in cancer patients, with pooled hazard ratio (HR) of 1.65 [95% confidence interval (CI) 1.44-1.88, p<0.00001] indicated by a fixed-effects model (I2=35%, p=0.11). In conclusion, the present meta-analysis demonstrated that high expression of UCA1 might serve as a common molecular marker for predicting lymph node metastasis and prognosis in various cancers. PMID- 27713162 TI - MTOR inhibition reversed drug resistance after combination radiation with erlotinib in lung adenocarcinoma. AB - OBJECTIVE: To investigate the effects of mTOR inhibition on drug resistance in lung adenocarcinoma after combined radiation and erlotinib therapy. RESULTS: Combined radiation and erlotinib therapy produced clear radiosensitization effects both in vitro and in vivo; however, tumor cells remained drug resistant. Additionally, combined radiation and erlotinib therapy significantly increased p AKT and p-P70 levels. After mTOR inhibition, the number of surviving cells significantly decreased compared with that before inhibition, and the in vivo growth curve was significantly reduced. METHODS: The effects of combined radiation and erlotinib therapy on tumor inhibition and drug resistance were evaluated by in vitro survival curves in PC9 lung adenocarcinoma cell line and in vivo growth curves in nude mouse xenograft tumor model respectively. The association between tumor drug resistance and the phosphatidylinositol 3 kinase/protein kinase B/mechanistic target of rapamycin (PI3K-AKT-mTOR) pathway was measured by western blot, assessing the changes in protein kinase B (AKT), phosphor-AKT (p-AKT), P70, and p-P70 protein levels. MTOR was inhibited using everolimus, and changes in AKT, p-AKT, P70, and p-P70 levels were observed. Furthermore, changes in in vitro survival curves, and in vivo growth curves before and after mTOR inhibition were evaluated to confirm its effects on drug resistance in lung adenocarcinoma after combined radiation and TKI therapy. CONCLUSION: mTOR was associated with drug resistance in lung adenocarcinoma after radiation combined with TKI, and MTOR inhibition reversed drug resistance in lung adenocarcinoma after combined radiation and TKI therapy. PMID- 27713160 TI - Role of BCL9L in transforming growth factor-beta (TGF-beta)-induced epithelial-to mesenchymal-transition (EMT) and metastasis of pancreatic cancer. AB - Pancreatic ductal adenocarcinoma (PDAC) has a low overall survival rate, which is approximately 20% during the first year and decreases to less than 6% within five years of the disease. This is due to premature dissemination accompanied by a lack of disease-specific symptoms during the initial stages. Additionally, to date there are no biomarkers for an early prognosis available.A growing number of studies indicate that epithelial to mesenchymal transition (EMT), triggered by WNT-, TGF-beta- and other signaling pathways is crucial for the initiation of the metastatic process in PDAC. Here we show, that BCL9L is up-regulated in PDAC cell lines and patient tissue compared to non-cancer controls. RNAi-induced BCL9L knockdown negatively affected proliferation, migration and invasion of pancreatic cancer cells. On a molecular basis, BCL9L depletion provoked an increment of E cadherin protein levels, with concomitant increase of beta-catenin retention at the plasma membrane. This is linked to the induction of a strong epithelial phenotype in pancreatic cancer cells upon BCL9L knockdown even in the presence of the EMT-inducer TGF-beta. Finally, xenograft mouse models of pancreatic cancer revealed a highly significant reduction in the number of liver metastases upon BCL9L knockdown. Taken together, our findings underline the key importance of BCL9L for EMT and thus progression and metastasis of pancreatic cancer cells. Direct targeting of this protein might be a valuable approach to effectively antagonize invasion and metastasis of PDAC. PMID- 27713164 TI - Upregulation of HSF1 in estrogen receptor positive breast cancer. AB - Heat shock transcription factor 1 (HSF1), a key regulator of the heat-shock response, is deregulated in many cancers. HSF1 can mediate cancer cell survival and metastasis. High levels of HSF1 have been associated with poor prognosis in breast cancer. The nature of HSF1 upregulation needs to be validated in different cohorts to further validate its prognostic utility in breast cancer.We first evaluated its expression in a cohort of breast cancer tissue microarrays with Oncotype DX recurrence scores available using immunohistochemistry. To further confirm the clinical relevance and prognostic impact, mutational and methylation status of the gene were also assessed in The Cancer Genome Atlas and publically available microarray datasets.Immunohistochemical analysis showed that HSF1 expression is independent of Oncotype DX high recurrence score in ER-positive node-negative patients. Analysis of The Cancer Genome Atlas data revealed upregulation of HSF1 is not due to methylation or mutation. HSF1 copy number variations and amplifications (15%) were not associated with survival. In publicly available microarray datasets, a prognostic impact was observed in ER positive tumors, but not in ER-negative tumors. Patients with ER-positive tumors with high HSF1 levels were associated with shorter overall survival (P = 0.00045) and relapse-free survival (P = 0.0057). In multivariable analysis, HSF1 remained a significant prognostic parameter.The mRNA expression levels of HSF1 in ER positive breast cancer are associated with both shorter relapse-free and overall survival. This prognostic impact is specific to mRNA expression, but stayed insignificant by protein expression or by analyzing amplification events. PMID- 27713163 TI - Premalignant alteration assessment in liver-like tissue derived from embryonic stem cells by aristolochic acid I exposure. AB - The in vitro predictive evaluation of chemical carcinogenicity based on hepatic premalignance has so far not been established. Here, we report a novel approach to investigate the premalignant events triggered by human carcinogen aristolochic acid I (AAI) in the liver-like tissue derived from mouse embryonic stem cells. By AAI exposure, the liver-like tissue exhibited the paracrine interleukin-6 phenotypic characteristics. Hepatocytes expressed STAT3/p-STAT3, c-Myc and Lin28B in parallel. Some of them displayed the dedifferentiation characteristics, such as full of alpha-fetoprotein granules, increase in size, and nucleocytoplasmic shuttle of Oct4. When these cells were injected into mice, the xenografts mostly displayed the uniform area of hepatic-like tissue with malignant nuclei. The hepatic malignant markers, alpha-fetoprotein, cytokeratin 7 and cytokeratin 19, were co-expressed in albumin-positive areas, respectively. In conclusion, we established an approach to predict the hepatic premalignance triggered by carcinogen AAI. This premalignant assay system might aid to evaluate the effects of potential carcinogens in liver, and probably to screen the protecting against hepatocarcinogenic efficacy of pharmaceuticals in vitro. PMID- 27713165 TI - Generation of V alpha13/beta21+T cell specific target CML cells by TCR gene transfer. AB - Adoptive immunotherapy with antigen-specific T cells can be effective for treating melanoma and chronic myeloid leukemia (CML). However, to obtain sufficient antigen-specific T cells for treatment, the T cells have to be cultured for several weeks in vitro, but in vitro T cell expansion is difficult to control. Alternatively, the transfer of T cell receptors (TCRs) with defined antigen specificity into recipient T cells may be a simple solution for generating antigen-specific T cells. The objective of this study was to identify CML-associated, antigen-specific TCR genes and generate CML-associated, antigen specific T cells with T cell receptor (TCR) gene transfer. Our previous study has screened an oligoclonal Vbeta21 with a different oligoclonal Valpha partner in peripheral blood mononuclear cells (PBMCs) derived from patients with CML. In this study, oligoclonally expanded TCR alpha genes, which pair with TCR Vbeta21, were cloned into the pIRES eukaryotic expression vector (TCR Valpha-IRES Vbeta21). Next, two recombinant plasmids, TCR Valpha13-IRES-Vbeta21 and TCR Valpha18-IRES-Vbeta21, were successfully transferred into T cells, and the TCR gene-modified T cells acquired CML-specific cytotoxicity with the best cytotoxic effects for HLA-A11+ K562 cells observed for the TCR Valpha13/Vbeta21 gene redirected T cells. In summary, our data confirmed TCRValpha13/Vbeta21 as a CML associated, antigen-specific TCR. This study provided new evidence that genetically engineered antigen-specific TCR may become a druggable approach for gene therapy of CML. PMID- 27713166 TI - MFAP5 and TNNC1: Potential markers for predicting occult cervical lymphatic metastasis and prognosis in early stage tongue cancer. AB - The purpose of this study is to identify candidate genes that could predict prognosis of early-stage tongue squamous cell carcinoma (TSCC) and its occult cervical lymphatic metastasis by large-scale gene expression profiling. Tumor tissue and matched normal mucosa samples were collected from patients with TSCC and analyzed with Affymetrix HTA2.0 high-density oligonucleotide array. Differentially expressed genes in TSCC with cervical lymph node metastasis (CLNM) were further analyzed with Gene Ontology and Kyoto Encyclopedia of Genes and Genomes for their functions and related pathways. A total of 107 differentially expressed genes (p < 0.05) were identified by microarray in TSCC samples with CLNM (n = 6) compared to those without CLNM (n = 6). Genes involved in the cell matrix adherens junction and migration function including MFAP5, TNNC1, MGP, FBFBP1 and FBXO32 were selected and validated by RT-PCR in TSCC samples (n = 32). Of the five genes, MFAP5 and TNCC1 expressions were further validated by immohistochemistry (n = 61). The significant positive correlation between MFAP5 and TNNC1 expression (p<0.001) was observed. Notably, over-expression of MFAP5 and TNNC1 were correlated with CLNM, metastasis relapse-free survival and overall survival. Our findings indicated that MFAP5 and TNNC1 may be potential markers for predicting occult cervical lymphatic metastasis and prognosis of oral tongue carcinoma. PMID- 27713167 TI - Simultaneous high expression of PLD1 and Sp1 predicts a poor prognosis for pancreatic ductal adenocarcinoma patients. AB - Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease with few therapeutic options. Recently, insight into cancer biology suggested abnormal lipid metabolism to be a risk factor for human malignancies. As a key enzyme implicated in lipid metabolism, PLD1 was elevated in various human cancer associating with malignant phenotypes. However, little was known about its expression and function in PDAC. We showed that PLD1 was elevated in both the cell lines and clinical samples of PDAC, and it positively correlated with vascular invasion (p = 0.041) and responsible for a poor prognosis (p = 0.009). Meanwhile, we also found Sp1 to be elevated in the disease, correlating with vascular invasion (p = 0.007). Moreover, the correlation assay suggested that PLD1 positively correlated with Sp1 in the clinical sample (r = 0.390; p < 0.001) and the cell lines. Finally, we showed that co-high expression of both the factors confers the poorest prognosis for the patients, and that their simultaneous high expression might be an independent prognostic factor (p = 0.001; HR = 3.427; 95% CI 1.629-7.211). PMID- 27713168 TI - The Aurora kinase A inhibitor TC-A2317 disrupts mitotic progression and inhibits cancer cell proliferation. AB - Mitotic progression is crucial for the maintenance of chromosomal stability. A proper progression is ensured by the activities of multiple kinases. One of these enzymes, the serine/threonine kinase Aurora A, is required for proper mitosis through the regulation of centrosome and spindle assembly. In this study, we functionally characterized a newly developed Aurora kinase A inhibitor, TC-A2317. In human lung cancer cells, TC-A2317 slowed proliferation by causing aberrant formation of centrosome and microtubule spindles and prolonging the duration of mitosis. Abnormal mitotic progression led to accumulation of cells containing micronuclei or multinuclei. Furthermore, TC-A2317-treated cells underwent apoptosis, autophagy or senescence depending on cell type. In addition, TC-A2317 inactivated the spindle assembly checkpoint triggered by paclitaxel, thereby exacerbating mitotic catastrophe. Consistent with this, the expression level of Aurora A in tumors was inversely correlated with survival in lung cancer patients. Collectively, these data suggest that inhibition of Aurora kinase A using TC-A2317 is a promising target for anti-cancer therapeutics. PMID- 27713169 TI - A phase 1 study of oral ridaforolimus in pediatric patients with advanced solid tumors. AB - PURPOSE: Ridaforolimus is an investigational, potent, selective mTOR inhibitor. This study was conducted to determine the recommended phase 2 dose (RP2D), maximum tolerated dose, safety, pharmacokinetics, and antitumor activity of oral ridaforolimus in children with advanced solid tumors. EXPERIMENTAL DESIGN: In this phase 1, multicenter, open-label study in children aged 6 to <18 years with advanced solid tumors, ridaforolimus was administered orally for 5 consecutive days/week in 28-day cycles until progression, unacceptable toxicity, or consent withdrawal. Dose started at 22 mg/m2 and increased to 28 mg/m2 and 33 mg/m2, followed by expansion at the RP2D. RESULTS: Twenty patients were treated; 18 were evaluable for dose-limiting toxicities. One dose-limiting toxicity (grade 3 increased alanine aminotransferase) occurred in 1 patient at 33 mg/m2. Dose escalation concluded at 33 mg/m2; the maximum tolerated dose was not determined. The most common treatment-related adverse events (frequency >=40%) were manageable grade 1-2 stomatitis, thrombocytopenia, hypertriglyceridemia, increased alanine aminotransferase, fatigue, hypercholesterolemia, anemia, and increased aspartate aminotransferase. Ridaforolimus exposure at 28 mg/m2 and 33 mg/m2 exceeded adult target levels. The RP2D for oral ridaforolimus in children was defined as 33 mg/m2. Four patients received at least 4 cycles; 2 with pineoblastoma and diffuse intrinsic pontine glioma had stable disease for 12 and 46 cycles, respectively. CONCLUSIONS: Ridaforolimus is orally bioavailable and well tolerated in children with advanced solid tumors. The RP2D (33 mg/m2, 5 days/week) exceeds the adult RP2D. The favorable toxicity and pharmacokinetic profiles may allow for combination therapy, a promising therapeutic option in pediatric malignancies. PMID- 27713170 TI - Gremlin inhibits UV-induced skin cell damages via activating VEGFR2-Nrf2 signaling. AB - Ultra Violet (UV) radiation induces reactive oxygen species (ROS) production, DNA oxidation and single strand breaks (SSBs), which will eventually lead to skin cell damages or even skin cancer. Here, we tested the potential activity of gremlin, a novel vascular endothelial growth factor (VEGF) receptor 2 (VEGFR2) agonist, against UV-induced skin cell damages. We show that gremlin activated VEGFR2 and significantly inhibited UV-induced death and apoptosis of skin keratinocytes and fibroblasts. Pharmacological inhibition or shRNA-mediated knockdown of VEGFR2 almost abolished gremlin-mediated cytoprotection against UV in the skin cells. Further studies showed that gremlin activated VEGFR2 downstream NF-E2-related factor 2 (Nrf2) signaling, which appeared required for subsequent skin cell protection. Nrf2 shRNA knockdown or S40T dominant negative mutation largely inhibited gremlin-mediated skin cell protection against UV. At last, we show that gremlin dramatically inhibited UV-induced ROS production and DNA SSB formation in skin keratinocytes and fibroblasts. We conclude that gremlin protects skin cells from UV damages via activating VEGFR2-Nrf2 signaling. Gremlin could be further tested as a novel anti-UV skin protectant. PMID- 27713171 TI - Sulfuretin promotes osteoblastic differentiation in primary cultured osteoblasts and in vivo bone healing. AB - Although sulfuretin, the major flavonoid of Rhus verniciflua Stokes, has a variety of biological actions, its in vitro and in vivo effects on osteogenic potential remain poorly understood. The objective of the present study was to investigate the effects of sulfuretin on in vitro osteoblastic differentiation and the underlying signal pathway mechanisms in primary cultured osteoblasts and on in vivo bone formation using critical-sized calvarial defects in mice. Sulfuretin promoted osteogenic differentiation of primary osteoblasts, with increased ALP activity and mineralization, and upregulated differentiation markers, including ALP, osteocalcin, and osteopontin, in a concentration dependent manner. The expression levels of Runx2, BMP-2, and phospho-Smad1/5/8 were upregulated by sulfuretin. Moreover, sulfuretin increased phosphorylation of Akt, mTOR, ERK, and JNK. Furthermore, sulfuretin treatment increased mRNA expression of Wnt ligands, phosphorylation of GSK3, and nuclear beta-catenin protein expression. In vivo studies with calvarial bone defects revealed that sulfuretin significantly enhanced new bone formation by micro-computed tomography and histologic analysis. Collectively, these data suggest that sulfuretin acts through the activation of BMP, mTOR, Wnt/beta-catenin, and Runx2 signaling to promote in vitro osteoblast differentiation and facilitate in vivo bone regeneration, and might be have therapeutic benefits in bone disease and regeneration. PMID- 27713173 TI - Dot1l expression predicts adverse postoperative prognosis of patients with clear cell renal cell carcinoma. AB - BACKGROUND: Disruptor of telomeric silencing 1-like (Dot1l), a histone methyltransferase that targets the histone H3 lysine 79 (H3K79), has been reported that its high expression is associated with various cancers, while the association between Dot1l expression and clear-cell renal cell carcinoma (ccRCC) is still unknown. PATIENTS AND METHODS: We retrospectively enrolled 282 patients with ccRCC undergoing nephrectomy from a single institution between 2005 and 2007, with a median follow-up of 99 months. Dot1l expression was evaluated by immunohistochemistry in clinical specimens. We compared the clinical outcomes by Kaplan-Meier survival analyses and assessed the prognostic value of Dot1l expression. Harrell's concordance index (C-index) was used to assess the predictive accuracy of different prognostic models. RESULTS: Higher Dot1l expression indicated poorer OS (P<0.001) and RFS (P<0.001) in patients with ccRCC. Moreover, Dot1l expression could stratify ccRCC patients in pT stage, Fuhrman grade and SSIGN/ Leibovich subgroups, which might redefine individual risk stratification. Multivariate analyses further indicated that Dot1l expression was an independent prognostic factor for OS (P=0.007) and RFS (P=0.001). The prognostic accuracy of conventional prognostic models was notably improved with Dot1l integration. Two nomograms and calibration plots were built to predict OS and RFS for patients with ccRCC and performed better based on C index value. CONCLUSION: Dot1l expression is a promising independent prognostic indicator for postoperative recurrence and survival of patients with ccRCC. PMID- 27713174 TI - Protective effects of oxymatrine against arsenic trioxide-induced liver injury. AB - Oxymatrine, a quinolizidine natural drug extracted from Sophora japonica, has been reported to have neuroprotective effect and cardioprotective effect. However, the protective effect of oxymatrine on arsenic trioxide (As2O3)-induced liver injury has not been reported. In the present study, we investigated the protective effects of oxymatrine on As2O3-induced liver injury in rats. Male Wistar rats were administrated 3mg/kg As2O3 intravenous injection on alternate days for 4 days. Oxymatrine was given 1 h before As2O3 treatment. The results showed that oxymatrine inhibited As2O3-induced hepatic pathological damage, liver ROS level and MDA level in a dose-dependent manner. As2O3 decreased the antioxidant enzymes SOD, GPX, and CAT activity and the decrease was inhibited by treatment of oxymatrine. Furthermore, oxymatrine attenuated the retention of arsenic in liver tissues and improved the expression of Nrf2 and HO-1. In conclusion, our results suggested that oxymatrine protected against As2O3-induced oxidative damage by activating Nrf2/HO-1 signaling pathway. PMID- 27713172 TI - Blood and lung microRNAs as biomarkers of pulmonary tumorigenesis in cigarette smoke-exposed mice. AB - Cigarette smoke (CS) is known to dysregulate microRNA expression profiles in the lungs of mice, rats, and humans, thereby modulating several pathways involved in lung carcinogenesis and other CS-related diseases. We designed a study aimed at evaluating (a) the expression of 1135 microRNAs in the lung of Swiss H mice exposed to mainstream CS during the first 4 months of life and thereafter kept in filtered air for an additional 3.5 months, (b) the relationship between lung microRNA profiles and histopathological alterations in the lung, (c) intergender differences in microRNA expression, and (d) the comparison with microRNA profiles in blood serum. CS caused multiple histopathological alterations in the lung, which were almost absent in sham-exposed mice. An extensive microRNA dysregulation was detected in the lung of CS-exposed mice. Modulation of microRNA profiles was specifically related to the histopathological picture, no effect being detected in lung fragments with non-neoplastic lung diseases (emphysema or alveolar epithelial hyperplasia), whereas a close association occurred with the presence and multiplicity of preneoplastic lesions (microadenomas) and benign lung tumors (adenomas). Three microRNAs regulating estrogen and HER2-dependent mechanisms were modulated in the lung of adenoma-bearing female mice. Blood microRNAs were also modulated in mice affected by early neoplastic lesions. However, there was a poor association between lung microRNAs and circulating microRNAs, which can be ascribed to an impaired release of mature microRNAs from the damaged lung. Studies in progress are evaluating the feasibility of analyzing blood microRNAs as a molecular tool for lung cancer secondary prevention. PMID- 27713175 TI - Fatty acid synthase is a primary target of MiR-15a and MiR-16-1 in breast cancer. AB - Fatty acid synthase (FASN) is upregulated in breast cancer and correlates with poor prognosis. FASN contributes to mammary oncogenesis and serves as a bona fide target in cancer therapies. MicroRNAs inhibit gene expression through blocking mRNA translation or promoting mRNA degradation by targeting their 3'-UTRs. We identified four microRNAs in two microRNA clusters miR-15a-16-1 and miR-497-195 that share a common seed sequence to target the 3'-UTR of the FASN mRNA. In reporter assays, both of these microRNA clusters inhibited the expression of a reporter construct containing the FASN 3'-UTR. However, only ectopic miR-15a-16 1, but not miR-497-195, markedly reduced the levels of endogenous FASN in breast cancer cells. Both miR-15a and miR-16-1 contributes to inhibiting FASN expression and breast cancer cell proliferation. Consistently, a sponge construct consisting of eight repeats of the FASN 3'-UTR region targeted by these microRNAs could markedly increase endogenous FASN levels in mammary cells. When FASN expression was restored by ectopic expression in breast cancer cells, retarded cell proliferation caused by miR-15a-16-1 was partially rescued. In conclusion, we demonstrated that FASN expression is primarily downregulated by miR-15a and miR 16-1 in mammary cells and FASN is one of the major targets of these two tumor suppressive microRNAs. PMID- 27713176 TI - A functional signal profiling test for identifying a subset of HER2-negative breast cancers with abnormally amplified HER2 signaling activity. AB - The results of clinical trials evaluating the efficacy of HER2 inhibitors in patients with breast cancer indicate that the correlation between HER2 receptor levels and patient outcomes is as low as 50%. The relatively weak correlation between HER2 status and response to HER2-targeting drugs suggests that measurement of HER2 signaling activity, rather than absolute HER2 levels, may more accurately diagnose HER2-driven breast cancer. A new diagnostic test, the CELx HER2 Signaling Profile (CELx HSP) test, is demonstrated to measure real-time HER2 signaling function in live primary cells. In the present study, epithelial cells extracted fresh from breast cancer patient tumors classified as HER2 negative (HER2-, n = 34 of which 33 were estrogen receptor positive) and healthy subjects (n = 16) were evaluated along with reference breast cancer cell lines (n = 19). Live cell response to specific HER2 agonists (NRG1b and EGF) and antagonist (pertuzumab) was measured. Of the HER2- breast tumor cell samples tested, 7 of 34 patients (20.5%; 95% CI = 10%-37%) had HER2 signaling activity that was characterized as abnormally high. Amongst the tumor samples there was no correlation between HER2 protein status (by cell cytometry) and HER2 signaling activity (hyperactive or normal) (Regression analysis P = 0.144, R2 = 0.068). One conclusion is that measurement of HER2 signaling activity can identify a subset of breast cancers with normal HER2 receptor levels with abnormally high levels of HER2 signaling. This result constitutes a new subtype of breast cancer that should be considered for treatment with HER2 pathway inhibitors. PMID- 27713180 TI - The Kondo tip decorated by the Co atom. AB - The Kondo effect of single Co adatoms on Ru(0001) is detected with two different kinds of co-decorated tip (Kondo tip) by using low temperature scanning tunneling microscopy and scanning tunneling spectroscopy. We call the relatively separated two magnetic impurities in the tunneling region 'two Kondo system' to distinguish it from the 'two-impurity Kondo system'. We find that the artificially constructed Kondo tips can be generally categorized into two types of Kondo resonances, which have distinct Fano line shapes with quantum interference factor |q| ? 1 and |q| ~ 1, respectively. The tunneling spectra of six constructed two Kondo systems can be well fitted by summing the two Fano resonances of the two subsystems and a linear background. More interestingly, by extracting the amplitudes of the two Fano resonances in the spectra, we find that the electron transmission of such a two Kondo system in the tunneling region is dominated by the quantum interference of the Kondo tip, which is directly related to the geometric configuration of the adsorbed Kondo atom on the tip. PMID- 27713177 TI - LDB1 overexpression is a negative prognostic factor in colorectal cancer. AB - BACKGROUND: Colorectal cancer (CRC) is the third most common cancer in western countries and is driven by the Wnt signaling pathway. LIM-domain-binding protein 1 (LDB1) interacts with the Wnt signaling pathway and has been connected to malignant diseases. We therefore aimed to evaluate the role of LDB1 in CRC. RESULTS: Overexpression of LDB1 in CRC is associated with strikingly reduced overall and metastasis free survival in all three independent patient cohorts. The expression of LDB1 positively correlates with genes involved in the Wnt signaling pathway (CTNNB1, AXIN2, MYC and CCND1). Overexpression of LDB1 in CRC cell lines induced Wnt pathway upregulation as well as increased invasivity and proliferation. Upon separate analysis, the role of LDB1 proved to be more prominent in proximal CRC, whereas distal CRC seems to be less influenced by LDB1. MATERIALS AND METHODS: The expression of LDB1 was measured via RT-qPCR in 59 clinical tumor and normal mucosa samples and correlated to clinical end points. The role of LDB1 was examined in two additional large patient cohorts from publicly available microarray and RNAseq datasets. Functional characterization was done by lentiviral overexpression of LDB1 in CRC cell lines and TOP/FOP, proliferation and scratch assays. CONCLUSIONS: LDB1 has a strong role in CRC progression, confirmed in three large, independent patient cohorts. The in vitro data confirm an influence of LDB1 on the Wnt signaling pathway and tumor cell proliferation. LDB1 seems to have a more prominent role in proximal CRC, which confirms the different biology of proximal and distal CRC. PMID- 27713178 TI - Impact of Polo-like kinase 1 inhibitors on human adipose tissue-derived mesenchymal stem cells. AB - Polo-like kinase 1 (Plk1) has been established as one of the most promising targets for molecular anticancer intervention. In fact, various Plk1 inhibitors have been identified and characterized. While the data derived from the bench are prospective, the clinical outcomes are less encouraging by showing modest efficacy. One of the explanations for this discrepancy could be unintendedly targeting of non-malignant cells by Plk1 inhibitors. In this work, we have addressed the effect of Plk1 inhibition in adipose tissue-derived mesenchymal stem cells (ASCs). We show that both visceral and subcutaneous ASCs display monopolar spindles, reduced viability and strong apoptosis induction upon treatment with BI 2536 and BI 6727, the Plk1 kinase domain inhibitors, and with Poloxin, the regulatory Polo-box domain inhibitor. While Poloxin triggers quickly apoptosis, BI 2536 and BI 6727 result in mitotic arrest in ASCs. Importantly, survived ASCs exhibit DNA damage and a pronounced senescent phenotype. In addition, Plk1 inhibition impairs ASCs' motility and homing ability. These results show that Plk1 inhibitors target slowly proliferating ASCs, an important population of anti-inflammation and immune modulation. The toxic effects on primary cells like ASCs could be partially responsible for the reported moderate antitumor activity in patients treated with Plk1 inhibitors. PMID- 27713181 TI - Reduction of magnetic damping and isotropic coercivity and increase of saturation magnetization in Rh-incorporated CoIr system. AB - Replacing Ir with Rh in a CoIr system possessing negative uniaxial magnetocrystalline anisotropy (K u ) substantially reduces its magnetic damping and coercivity by more than half while retaining its high negative K u . Moreover, a higher saturation magnetization (M s ) and more isotropic coercivity are achieved. Such material development makes it particularly suitable for use as the soft underlayer (SUL) of magnetic recording media for reducing noise, and as the oscillation layer of a spin-torque oscillator (STO) for achieving higher oscillation frequency, larger AC magnetic field and lower driving current, which can be readily integrated with the current recording head for microwave-assisted magnetic recording. Finally, we recommend a composite free layer by coupling CoIr with a spin polarizer (Co or Co/Cu/Co) for the enhancement of the spin polarization rate and, therefore, the improvement of STO efficiency. These could pave the way for CoIr-based materials to be implemented in devices requiring a negative Ku with low damping and high 'softness', such as oscillators.

AB - Limited data exists regarding the combination of Hedgehog signaling (Hh) inhibition and radiotherapy, even though there are several indications that this might be a promising treatment strategy. In this study, we evaluated the combination of two Hh inhibitors, the SMO inhibitor GDC-0449 and the GLI inhibitor GANT61 with radiotherapy in different prostate cancer (PCa) models. In vitro, GANT61 was able to sensitize 22Rv1 PCa cells but not PC3 and DU145 PCa cells. The lack of radiosensitization in the latter cell lines was shown to be dependent on the presence of mutated p53. Introduction of WT p53 into PC3 cells resulted in radiosensization following GANT61 treatment, suggesting that the p53 transcription factor plays an important role in the GANT61-induced radiosensitization in vitro. Targeting at the level of SMO (GDC-0449) did not show cytotoxicity or synergy with radiation. Furthermore, we confirmed the radiosensitization effect of GANT61 in two in vivo xenograft PCa models. The decrease in tumor growth was associated with decreased proliferation and increased apoptosis. In conclusion, we provide evidence that GANT61 in combination with radiation treatment might represent a promising therapeutic strategy for enhancing the radiation response of PCa patients. PMID- 27713182 TI - Vertical Si nanowire arrays fabricated by magnetically guided metal-assisted chemical etching. AB - In this work, vertically aligned Si nanowire arrays were fabricated by magnetically guided metal-assisted directional chemical etching. Using an anodized aluminum oxide template as a shadow mask, nanoscale Ni dot arrays were fabricated on an Si wafer to serve as a mask to protect the Si during the etching. For the magnetically guided chemical etching, we deposited a tri-layer metal catalyst (Au/Fe/Au) in a Swiss-cheese configuration and etched the sample under the magnetic field to improve the directionality of the Si nanowire etching and increase the etching rate along the vertical direction. After the etching, the nanowires were dried with minimal surface-tension-induced aggregation by utilizing a supercritical CO2 drying procedure. High-resolution transmission electron microscopy (HR-TEM) analysis confirmed the formation of single-crystal Si nanowires. The method developed here for producing vertically aligned Si nanowire arrays could find a wide range of applications in electrochemical and electronic devices. PMID- 27713183 TI - Recombination dynamics in aerotaxy-grown Zn-doped GaAs nanowires. AB - In this paper we have investigated the dynamics of photo-generated charge carriers in a series of aerotaxy-grown GaAs nanowires (NWs) with different levels of Zn doping. Time-resolved photo-induced luminescence and transient absorption have been employed to investigate radiative (band edge transition) and non radiative charge recombination processes, respectively. We find that the photo luminescence (PL) lifetime of intrinsic GaAs NWs is significantly increased after growing an AlGaAs shell over them, indicating that an AlGaAs shell can effectively passivate the surface of aerotaxy-grown GaAs NWs. We observe that PL decay time as well as PL intensity decrease with increasing Zn doping, which can be attributed to thermally activated electron trapping with the trap density increased due to the Zn doping level. PMID- 27713184 TI - Quenching of the luminescence intensity of GaN nanowires under electron beam exposure: impact of C adsorption on the exciton lifetime. AB - Electron irradiation of GaN nanowires in a scanning electron microscope strongly reduces their luminous efficiency as shown by cathodoluminescence imaging and spectroscopy. We demonstrate that this luminescence quenching originates from a combination of charge trapping at already existing surface states and the formation of new surface states induced by the adsorption of C on the nanowire sidewalls. The interplay of these effects leads to a complex temporal evolution of the quenching, which strongly depends on the incident electron dose per area. Time-resolved photoluminescence measurements on electron-irradiated samples reveal that the carbonaceous adlayer affects both the nonradiative and the radiative recombination dynamics.

AB - We report on the coupling of single nitrogen vacancy (NV) centers to ultrathin fiber-taper nanofibers by the manipulation of single diamond nanocrystals on the nanofibers under real-time observation of nanodiamond fluorescence. Spin dependent fluorescence of the single NV centers is efficiently detected through the nanofiber. We show control of the spin sub-level structure of the electronic ground state using an external magnetic field and clearly observe a frequency fine tuning of [Formula: see text]. This observation demonstrates a possibility of realizing fiber-integrated quantum lambda-systems, which can be used for various quantum information devices including push-pull quantum memory and quantum gates. PMID- 27713186 TI - Fluorescent protein integrated white LEDs for displays. AB - The usage time of displays (e.g., TVs, mobile phones, etc) is in general shorter than their functional life time, which worsens the electronic waste (e-waste) problem around the world. The integration of biomaterials into electronics can help to reduce the e-waste problem. In this study, we demonstrate fluorescent protein integrated white LEDs to use as a backlight source for liquid crystal (LC) displays for the first time. We express and purify enhanced green fluorescent protein (eGFP) and monomeric Cherry protein (mCherry), and afterward we integrate these proteins as a wavelength-converter on a blue LED chip. The protein-integrated backlight exhibits a high luminous efficacy of 248 lm/Wopt and the area of the gamut covers 80% of the NTSC color gamut. The resultant colors and objects in the image on the display can be well observed and distinguished. Therefore, fluorescent proteins show promise for display applications. PMID- 27713187 TI - Transforming gate misalignment into a unique opportunity to facilitate steep switching in junctionless nanotransistors. AB - In this work, we examine the feasibility of triggering impact ionisation at sub bandgap voltages through optimal utilisation of structural non-ideality induced electric field redistribution in the semiconductor film for an energy efficient steep switching junctionless (JL) transistor. While misalignment between front and back gates is often considered as a disadvantage due to loss of gate controllability, the work highlights its usefulness and applicability in nanoscale devices to engineer the electric field to enhance the product of current density (J) and electric field (E) and activate impact ionisation at sub bandgap applied voltages. Results show that intentionally misaligned gates in silicon and germanium based JL devices exhibit an inclined conduction channel and achieve a nearly ideal value of steep subthreshold swing (~ 1 mV decade-1) at room temperature. The work provides new viewpoints to realise energy efficient JL devices through the sharp increase of drain current from off-state to on-state achieved due to intentional misalignment between front and back gates.

AB - First-principles calculations based on density-functional theory including anharmonicity within the variational stochastic self-consistent harmonic approximation are applied to understand how the quantum character of the proton affects the candidate metallic molecular Cmca - 4 structure of hydrogen in the 400-450 GPa pressure range, where metallization of hydrogen is expected to occur. Anharmonic effects, which become crucial due to the zero-point motion, have a large impact on the hydrogen molecules by increasing the intramolecular distance by approximately a 6%. This induces two new electron pockets at the Fermi surface opening new scattering channels for the electron-phonon interaction. Consequently, the electron-phonon coupling constant and the superconducting critical temperature are approximately doubled by anharmonicity and Cmca - 4 hydrogen becomes a superconductor above 200 K in all the studied pressure range. Contrary to many superconducting hydrides, where anharmoncity tends to lower the superconducting critical temperature, our results show that it can enhance superconductivity in molecular hydrogen. PMID- 27713190 TI - Stretchable and transparent electrodes based on patterned silver nanowires by laser-induced forward transfer for non-contacted printing techniques. AB - Silver nanowires (AgNWs) are excellent candidate electrode materials in next generation wearable devices due to their high flexibility and high conductivity. In particular, patterning techniques for AgNWs electrode manufacture are very important in the roll-to-roll printing process to achieve high throughput and special performance production. It is also essential to realize a non-contact mode patterning for devices in order to keep the pre-patterned components away from mechanical damages. Here, we report a successful non-contact patterning of AgNWs-based stretchable and transparent electrodes by laser-induced forward transfer (LIFT) technique. The technique was used to fabricate a 100% stretchable electrode with a width of 200 MUm and electrical resistivity 10-4 Omegacm. Experiments conducted integrating the stretchable electrode on rubber substrate in which LED was pre-fabricated showed design flexibility resulting from non contact printing. Further, a patterned transparent electrode showed over 80% in optical transmittance and less than 100 Omega sq-1 in sheet resistance by the optimized LIFT technique. PMID- 27713191 TI - Not ery small bowel submucosal mass is a GIST A rare case of small bowel schwannoma. AB - INTRODUCTION: Schwannomas are slow-growing tumors, rarely occurring in the GI tract. When found, their location is mostly in the stomach. Presentation in the small bowel is extremely rare, anecdotal. CASE REPORT: We present the case of a 47-year old male who underwent laparoscopic elective left hemicolectomy for recurrent diverticulitis. RESULTS: At surgery an exophytic mass originating from the first jejunal loop was identified and resected, under the suspicion of a GIST. Post-operative pathologic report was consistent with the diagnosis of jejunal schwannoma. Unfortunately resection margins were positive and the patient was taken back to the OR for an additional jejunal segmental resection. CONCLUSIONS: GI schwannomas have excellent prognosis after surgical resection. It is important to differentiate them from GISTs, which may have a malignant behavior in 10-30% of the cases. To ensure complete surgical resection with negative margins is mandatory and is the curative treatment of choice.

PMID- 27713193 TI - [Prevention and Treatment Strategy for Infectious Complication after Lung Transplantation]. AB - The most frequent cause of death within a year after lung transplantation is infectious complications, which shifts to chronic allograft rejection or chronic lung allograft dysfunction(CLAD) thereafter. It is no doubt that minimization of the dose of immunosuppression within the acceptable therapeutic range is a best strategy to avoid infectious complications however, adequate dose of immunosuppressant is mandatory to protect lung allografts from acute or chronic rejection. Carefully balanced therapy of immunosuppression and infection control is extremely important for patient's long term survival after lung transplantation. Total 344 transplants were performed in Japan until the end of 2013, and the 5-year post-operative survival was reported as more than 70% which is superior than North American or European registry data. However, more than 30% of death is still caused by infectious complications thus appropriate prevention and treatment for infection is important for better long term results. Here in this paper, the 1st 10-year experience of Fukuoka University Lung Transplant Program was reported and discussed especially focusing on infectious complications. PMID- 27713192 TI - [Infectious Diseases after Lung Transplantation]. AB - Lung transplantation is getting to be a common treatment for the end-stage respiratory failure. Therefore we might encounter the various issues associated with infection under immunosuppression. At 1st, virus infections occur by Cytomegalovirus, Epstein-Barr virus, hepatitis B and C virus and John Cunningham virus. The 2nd, bacterial infections exacerbate graft condition by methicillin resistant Staphylococcus aureus, Pseudomonas, Burkholderia cepacia and coagulase negative staphylococci. The 3rd, fungal infections are induced by Aspergillus, Candida and Cryptococcus. Lastly there is mycobacterial infection. These opportunistic infections contribute poor prognosis for lung transplant recipients, so that we have to manage these infectious diseases. PMID- 27713195 TI - [Cardiac Function after Lung Transplantation of Eisenmenger Syndrome]. AB - Eisenmenger syndrome(ES) could occur at the end-stage of congenital heart disease and is one of the indications for lung transplantation. Survival following heart lung transplantation is better than that following bilateral lung transplantation (LT). However, in Japan, because of limitations in regard to the numbers of donors available, LT with cardiac repair is usually chosen. Following LT with cardiac repair, careful management of the repaired heart is necessary, though there are few reports available regarding such postoperative cardiac management. Here, we present findings from careful postoperative monitoring and management of cardiac function in a patient with ES with a ventricular septal defect, for whom LT with cardiac repair was performed. In addition, follow-up results of cardiac function are presented as well as discussion of important points related to such cases. PMID- 27713194 TI - [Anti-thymocyte Globulin Therapy for Cases of Acute Rejection Following Lung Transplantation]. AB - A 58-year-old male underwent right lung transplantation from a brain-dead donor, after which acute rejection developed that was resistant to steroid pulse therapy. Rabbit-derived anti-thymocyte globulin (rATG) therapy was successful for controlling the rejection. However, following that therapy, the patient was affected by an opportunistic infection and suffered from repeated empyema. It is important to pay attention to immunosuppressive agent levels in blood following treatment, because ATG is a potent immunosuppressive drug and its effects can continue for more than 6 months after administration. PMID- 27713196 TI - [Overview of Clinical Issues after Lung Transplantation]. AB - Lung allograft encounters changeable issues over the pre-and postransplant period. It is important to realize individual problems in each specific peritransplant stage and share the awareness between transplant team and patients. Long-sighted management policy is encouraged throughout posttransplant care because morbidities in each stage trigger each other and graft condition and management in acute posttransplant period have a considerable impact on long-term recipient survival after lung transplantation. The specific issues at hand are reviewed by going through the current important literature. PMID- 27713197 TI - [Anastomotic Airway Complications after Lung Transplantation]. AB - Anastomotic airway complications still remain an important issue after lung transplantation. Most of the complications are stenosis and anastomotic leakage. Stent insertion is one option for the stenosis. We review the anastomotic airway complications and report our recent experience of stent insertion using 3 dimensional printed airway model. PMID- 27713198 TI - [The History and Development of Experimental Rodent Models of Chronic Lung Allograft Dysfunction after Lung Transplantation]. AB - Chronic lung allograft dysfunction (CLAD) is a critical impediment to the long term survival after lung transplantation. A rat orthotopic lung transplantation model was developed in the early 1970s, and using this model, our laboratory has shown that the immunopathogenesis of CLAD involves both allogeneic immunity and autoimmunity. However, further investigation of CLAD is limited by the scarcity of transgenic and knockout strains. The model most widely used to study CLAD, the mouse model of heterotopic tracheal transplantation, has some incomplete pathophysiologic features of CLAD, which limits the utility of this model. Unlike other solid organ transplants, vascularized and aerated murine lung transplantation has only recently been developed. We have also reported that minor, but not major, histocompatibility antigens mismatch induced the development of CLAD in murine orthotopic lung transplants and that CLAD development was interleukin-17-dependent. This mini-review underscores the history and development of rodent models of CLAD after lung transplant, including the findings from our previous studies. In addition, the future direction of rodent models is also discussed. PMID- 27713199 TI - [Development of Personalized and Targeted Preventive Therapies for Chronic Lung Allograft Dysfunction Subtypes;A Novel Strategy]. AB - Chronic lung allograft dysfunction (CLAD) is a major limitation to long-term success of lung transplantation. Restrictive allograft syndrome (RAS) is a recently discovered subtype of CLAD, showing distinct clinical, pathological and radiological features compared with the major CLAD subtype, bronchiolitis obliterans syndrome (BOS). Introduction of the novel CLAD classification system that differentiates CLAD into BOS and RAS has stimulated research activities aiming delineation of the underlying pathological mechanism in the 2 CLAD subtypes. Accumulating evidences suggest that BOS and RAS could be biologically distinct, indicating that optimal therapeutic strategy could be different. Further efforts in refinements in biologic profiling of BOS and RAS will lead to a better understanding of CLAD, as well as the development of personalized and targeted preventive therapies for underlying CLAD subtypes. PMID- 27713200 TI - [Characteristics of Postoperative Malignancies after Lung Transplantation]. AB - Patients after lung transplantation are at risk for postoperative malignancy mainly due to postoperative immunosuppression. Skin cancer and post-transplant lymphoproliferative disorder (PTLD) are common in Western countries. We retrospectively reviewed the medical records of 120 patients undergoing lung transplantation between April 2002 and July 2015 at Kyoto University. Postoperative malignancy developed in 14 patients(11.7%):PTLD in 8, gastric cancer in 2, breast cancer in 1, glioblastoma in 1, lung cancer in 1, and adenocarcinoma of unknown primary in 1. Seven patients(11.3%)and 7 patients (12.1%)were after living-donor lung transplantation( LDLLT) and cadaveric lung transplantation (CLT), respectively (p=1.00). The overall 5-year survival of patients with postoperative malignancy was 39.3%, which tended to be worse (p=0.059), compared to those without postoperative malignancy(71.4%). All postoperative malignancies were de novo malignancies without any recurrence of original malignancies. Postoperative malignancies occurred after LDLLT as well as after CLT, and seemed to have a negative impact on long-term outcome of lung transplant recipients. The majority was PTLD;however, skin cancer was not recognized, suggesting ethnic differences. We should be careful about postoperative malignancies in follow-up of the lung transplant recipients. PMID- 27713201 TI - [Fatal Respiratory Failure Developed during Chemotherapy for Diffuse Large B Cell Lymphoma that Occurred Late after Lung Transplantation]. AB - We report here a case of fatal respiratory failure developed during chemotherapy for diffuse large B cell lymphoma that occurred late after lung transplantation. 25-year- old man underwent lung transplantation from brain death donor for respiratory failure due to interstitial pneumonia at the age of 16 years old. Two years after transplantation, his respiratory function decreased gradually. Chronic lung allograft dysfunction including bronchiolitis obliterans( BOS) and restrictive allograft syndrome was suspected and immunosuppression was enhanced. Nine years after transplantation, he had abdominal pain and physical examination suggested intestinal obstruction. Small intestine endoscopy revealed an ulcer at jejunum and diffuse large B cell lymphoma( DLBCL) was finally diagnosed by biopsy. Chemotherapy was planned for lymphoma, but respiratory failure progressed just before chemotherapy. Chest computed tomography showed infiltrative shadow in right lung, so we suspected presence of lymphoma and chemotherapy was carried out. After chemotherapy, abnormal shadow in the right lung disappeared. Although chemotherapy was effective, respiratory failure progressed and he died. Pathological examination from autopsy showed mixture of BOS, diffuse alveolar damage, invasion of aspergillus and acute fibrinoid organizing pneumonia but no residual DLBCL was found in the lung. PMID- 27713202 TI - [Unplanned Ascending Aortic Graft Replacement at Valvuler Surgery in a Patient with Systemic Lupus Erythematosus;Report of a Case]. AB - A 65-year-old woman with severe mitral stenosis was admitted to our hospital. She had been previously diagnosed with systemic lupus erythematosus (SLE) and had been taking prednisolone (5 mg/day) for 19 years. As SLE patients with prolonged steroid use are known to be at risk of an aortic dissection and aneurysm, femoral artery was chosen for arterial perfusion to reduce the risk of a dissection of the ascending aorta. However, hemostasis was difficult at the insertion point of the catheter to infuse the antegrade cardioplegic solution. An ascending aortic graft replacement was therefore performed. Histopathological examination of the aortic wall showed the presence of intimal hypertrophy and a decrease in elastic fiber content but without any evidence of vasculitis. Because prolonged steroids use is a risk factor of atherosclerotic change in the aortic wall, the aorta should be treated carefully during cardiovascular surgery in such patients. PMID- 27713203 TI - [Left Ventricular Patch Plasty for Post-infarct Ventricular True Aneurysm with Ventricular Septal Perforation;Report of a Case]. AB - We experienced a rare case of post-infarct left ventricular aneurysm (LVA) and ventricular septal perforation (VSP). An 83-year-old woman was treated for acute cardiac insufficiency. Three weeks later after hospitalization, she had sudden cardiorespiratory failure and was diagnosed with VSP and LVA. She underwent emergency heart surgery. After establishing extracorporeal circulation, the LVA was excised longitudinally from the left side of the left anterior descending branch. Endoventricular patch plasty (Dor procedure) was performed to exclude the ventricular aneurysm, and the VSP was closed using Dacron patch. After surgery, echocardiography found no residual shunts and exclusion of the LVA. The patient underwent successful surgical treatment of VSP and LVA.

AB - A 52-years-old man, who had undergone coil embolization of saccular aneurysm of the brachiocephalic artery, presented with right back discomfort. Diagnosis by computed tomography was difficult because of an artifact from the coils. Angiography, on the other hand, revealed a rupture of the aneurysm, and emergency surgery was performed. A Y-shaped graft was anastomosed to the ascending aorta under partial clamp. Then, one of its branches was anastomosed to the common carotid artery also under partial clamp in an end-to-side fashion. The cerebral blood flow monitored by a regional oximetry system (INVOS) remained stable. The other branch was anastomosed to the subclavian artery in end-to end fashion. No postoperative neurologic complications occurred. Angiography was useful in diagnosis of brachiocephalic artery aneurysm rupture after coil embolization. INVOS was also useful for monitoring the cerebral blood flow during surgery. PMID- 27713205 TI - [Reconstruction of Unilateral Absent Pulmonary Artery Using Ringed Prosthetic Graft;Report of a Case]. AB - We have repaired a unilateral absent pulmonary artery(UAPA) using a prosthetic graft with a ring. Case 1 was a 1-month old girl. The right pulmonary artery(RPA) was anti-anatomically reconstructed with a 4 mm ePTFE graft. In postoperative year 1, however, the graft became stenosed due to compression by the ascending aorta. We reversed the stenosis with a 6 mm stent by percutaneous transluminal angioplasty. Case 2 was 6-year old boy. His RPA was anatomically reconstructed with a ringed 5 mm ePTFE graft when he was 5-months old. In postoperative year 6, he needed the graft exchanged because of the relatively decreased pulmonary flow due to body growth. Therefore, we exchanged the graft with an anti-anatomically ringed 12 mm ePTFE graft. No graft stenosis was observed during the perioperative course. Using a prosthetic graft with a ring may be a good solution to avoid compression from the ascending aorta. PMID- 27713206 TI - Bacterial Community Shift during the Startup of a Full-Scale Oxidation Ditch Treating Sewage. AB - The oxidation ditch (OD) is one of the most widely used processes for treating municipal wastewater. However, the microbial communities in the OD systems have not been well characterized, and little information about the shift of bacterial community during the startup process of the OD systems is available. In this study, we investigated the bacterial community changes during the startup period (over 100 days) of a full-scale OD. The results showed that the bacterial community dramatically changed during the startup period. Similar to the activated sludge samples in other studies, Proteobacteria (accounting for 26.3% 48.4%) was the most dominant bacterial phylum in the OD system, but its relative abundance declined nearly 40% during the startup process. It was also found that Planctomycetes proliferated greatly (from 4.79% to 13.5%) and finally replaced Bacteroidetes as the second abundant phylum in the OD system. Specifically, some bacteria affiliated with genus Flavobacterium exhibited remarkable decreasing trends, whereas bacterial species belonging to the OD1 candidate division and Saprospiraceae family were found to increase during the startup process. Despite of the bacterial community shift, the organic matter, nitrogen, and phosphorus in the effluent were always in low concentrations, suggesting the functional redundancy of the bacterial community. Moreover, by comparing with the bacterial community in other municipal wastewater treatment bioreactors, some potentially novel bacterial species were found to be present in the OD system. Collectively, this study improved our understandings of the bacterial community structure and microbial ecology during the startup of a full-scale wastewater treatment bioreactor. PMID- 27713207 TI - Identification of a Bacillus thuringiensis Surface Layer Protein with Cytotoxic Activity against MDA-MB-231 Breast Cancer Cells. AB - In this work, we isolated a surface layer protein (SLP) from a Bacillus thuringiensis (Bt) strain to evaluate it cytotoxic effects against MDA-MB-231 human breast cancer cells. AP11 was selected from a group of Bt strains using SLP oligonucleotides developed from Bacillus conserved regions. The AP11 strain was grown in Luria Bertani medium until the late exponential phase; an 86 kDa protein was extracted using 5 M LiCl and identified by liquid chromatography- tandem mass spectrometry. It corresponded to a multispecies SLP highly similar to previously described SLPs in Bt. The MDA-MB-231 breast cancer cells LC50 was obtained using 0.25 MUg/ml of the isolated SLP. HaCat non-cancerous cells presented 90% survival using the same protein concentration. Our data suggest that SLP cytotoxicity against MDA-MB-231 could be induced by an interaction with the CDH11 cell membrane receptor. PMID- 27713208 TI - Antimicrobial Activity of Flaxseed Meal Extract against Escherichia coli O157:H7 and Staphylococcus aureus Inoculated on Red Mustard. AB - This study examined the antimicrobial activity of flaxseed meal extract (FME) against Staphylococcus aureus and Escherichia coli O157:H7 inoculated on red mustard. With the treatment of 0.7% FME for 3 min, the reduction levels of S. aureus and E. coli O157:H7 populations were 1.23 and 1.83 log CFU/g, respectively. In addition, the combined treatment of 0.7% FME at 50 degrees C for 3 min reduced the populations of the pathogenic bacteria by 2.28 and 2.41 log CFU/g, respectively. The color and the vitamin C content were not significantly different between treatments. Thus, FME can be used as a novel antimicrobial agent in freshcut vegetables. PMID- 27713209 TI - Virulence Factors and Stability of Coliphages Specific to Escherichia coli O157:H7 and to Various E. coli Infection. AB - Characteristics of E. coli O157:H7-specific infection bacteriophages (O157 coliphages) and broad-host-range bacteriophages for other E. coli serotypes (broad-host coliphages) were compared. The burst sizes of the two groups ranged from 40 to 176 PFU/infected cell. Distributions of the virulence factors stx1, stx2, ehxA, and saa between the two groups were not differentiated. Broad-host range coliphages showed lower stability at 70 degrees C, in relation to O157 coliphages. However, O157 coliphages showed high acid and ethanol tolerance by reduction of only 22% and 11% phages, respectively, under pH 3 and 70% ethanol for 1 h exposure. Therefore, these results revealed that the O157 coliphages might be more stable under harsh environments, which might explain their effective infection of the acid-tolerant E. coli O157:H7.

AB - Acetoin (AC) is a volatile platform compound with various potential industrial applications. AC contains two stereoisomeric forms: (3S)-AC and (3R)-AC. Optically pure AC is an important potential intermediate and widely used as a precursor to synthesize novel optically active materials. In this study, chiral (3R)-AC production from meso-2,3-butanediol (meso-2,3-BD) was obtained using recombinant Escherichia coli cells co-expressing meso-2,3-butanediol dehydrogenase (meso-2,3-BDH), NADH oxidase (NOX), and hemoglobin protein (VHB) from Serratia sp. T241, Lactobacillus brevis, and Vitreoscilla, respectively. The new biocatalyst of E. coli/pET-mbdh-nox-vgb was developed and the bioconversion conditions were optimized. Under the optimal conditions, 86.74 g/l of (3R)-AC with the productivity of 3.61 g/l/h and the stereoisomeric purity of 97.89% was achieved from 93.73 g/l meso-2,3-BD using the whole-cell biocatalyst. The yield and productivity were new records for (3R)-AC production. The results exhibit the industrial potential for (3R)-AC production via whole-cell biocatalysis. PMID- 27713211 TI - Characterization of Interphase Microbial Community in Luzhou-Flavored Liquor Manufacturing Pits of Various Ages by Polyphasic Detection Methods. AB - It is vital to understand the changing characteristics of interphase microbial communities and interspecies synergism during the fermentation of Chinese liquors. In this study, microbial communities in the three indispensable phases (pit mud, zaopei, and huangshui) of Luzhou-flavored liquor manufacturing pits and their shifts during cellars use were first investigated by polyphasic culture independent approaches. The archaeal and eubacterial communities in the three phases were quantitatively assessed by combined phospholipid ether lipids/phospholipid fatty acid analysis and fluorescence in situ hybridization. In addition, qualitative information regarding the microbial community was analyzed by PCR-denaturing gradient gel electrophoresis. Results suggested that the interphase microbial community profiles were quite different, and the proportions of specific microbial groups evolved gradually. Anaerobic bacteria and gram-positive bacteria were dominant and their numbers were higher in pit mud (109 cells/g) than in huangshui (107 cells/ml) and zaopei (107cells/g). Hydrogenotrophic methanogenic archaea were the dominant archaea, and their proportions were virtually unchanged in pit mud (around 65%), whereas they first increased and then decreased in zaopei (59%-82%-47%) and increased with pit age in huangshui (82%-92%). Interactions between microbial communities, especially between eubacteria and methanogens, played a key role in the formation of favorable niches for liquor fermentation. Furthermore, daqu (an essential saccharifying and fermentative agent) and metabolic regulation parameters greatly affected the microbial community. PMID- 27713212 TI - Isolation, Identification, and Expression of Microbial Cellulases from the Gut of Odontotermes formosanus. AB - Termites are destructive to agriculture, forestry, and buildings, but they can also promote agro-ecosystem balance through the degradation of lignocellulose. Termite-triggered cellulose digestion may be clarified through microbial metabolism of cellulose products. In the present study, we characterized the activities of cellulase and its three components synthesized by the cellulase producing fungal strain HDZK-BYTF620 isolated from the gut of Odontotermes formosanus. The protein components of cellulases were synthesized by strain HDZK BYTF620, which were isolated and characterized using polyacrylamide gel electrophoresis, and the expression of the cellulases was studied at the proteome level. PMID- 27713213 TI - Identification of Uncommon Candida Species Using Commercial Identification Systems. AB - Recently, several studies have revealed that commercial microbial identification systems do not accurately identify the uncommon causative species of candidiasis, including Candida famata, Meyerozyma guilliermondii, and C. auris. We investigated the accuracy of species-level identification in a collection of clinical isolates previously identified as C. famata (N = 38), C. lusitaniae (N = 1 2), and M. guilliermondii (N = 5) by the Vitek 2 system. All 55 isolates were re-analyzed by the Phoenix system (Becton Dickinson Diagnostics), two matrix assisted laser desorption ionization-time of flight mass spectrometry analyzers (a Vitek MS and a Bruker Biotyper), and by sequencing of internal transcribed spacer (ITS) regions or 26S rRNA gene D1/D2 domains. Among 38 isolates previously identified as C. famata by the Vitek 2 system, the majority (27/38 isolates, 71.1%) were identified as C. tropicalis (20 isolates) or C. albicans (7 isolates) by ITS sequencing, and none was identified as C. famata. Among 20 isolates that were identified as C. tropicalis, 17 (85%) were isolated from urine. The two isolates that were identified as C. auris by ITS sequencing originated from ear discharge. The Phoenix system did not accurately identify C. lusitaniae, C. krusei, or C. auris. The correct identification rate for 55 isolates was 92.7% (51/55 isolates) for the Vitek MS and 94.6% (52/55 isolates) for the Bruker Biotyper, as compared with results from ITS sequencing. These results suggest that C. famata is very rare in Korea, and that the possibility of misidentification should be noted when an uncommon Candida species is identified. PMID- 27713214 TI - Trametes villosa Lignin Peroxidase (TvLiP): Genetic and Molecular Characterization. AB - White-rot basidiomycetes are the organisms that decompose lignin most efficiently, and Trametes villosa is a promising species for ligninolytic enzyme production. There are several publications on T. villosa applications for lignin degradation regarding the expression and secretion of laccase and manganese peroxidase (MnP) but no reports on the identification and characterization of lignin peroxidase (LiP), a relevant enzyme for the efficient breakdown of lignin. The object of this study was to identify and partially characterize, for the first time, gDNA, mRNA, and the corresponding lignin peroxidase (TvLiP) protein from T. villosa strain CCMB561 from the Brazilian semiarid region. The presence of ligninolytic enzymes produced by this strain grown in inducer media was qualitatively and quantitatively analyzed by spectrophotometry, qPCR, and dye fading using Remazol Brilliant Blue R. The spectrophotometric analysis showed that LiP activity was higher than that of MnP. The greatest LiP expression as measured by qPCR occurred on the 7th day, and the ABSA medium (agar, sugarcane bagasse, and ammonium sulfate) was the best that favored LiP expression. The amplification of the TvLiP gene median region covering approximately 50% of the T. versicolor LPGIV gene (87% identity); the presence of Trp199, Leu115, Asp193, Trp199, and Ala203 in the translated amplicon of the T. villosa mRNA; and the close phylogenetic relationship between TvLiP and T. versicolor LiP all indicate that the target enzyme is a lignin peroxidase. Therefore, T. villosa CCMB561 has great potential for use as a LiP, MnP, and Lac producer for industrial applications. PMID- 27713215 TI - Structural Analyses of Zinc Finger Domains for Specific Interactions with DNA. AB - Zinc finger proteins are among the most extensively applied metalloproteins in the field of biotechnology owing to their unique structural and functional aspects as transcriptional and translational regulators. The classical zinc fingers are the largest family of zinc proteins and they provide critical roles in physiological systems from prokaryotes to eukaryotes. Two cysteine and two histidine residues (Cys2His2) coordinate to the zinc ion for the structural functions to generate a betabetaalpha fold, and this secondary structure supports specific interactions with their binding partners, including DNA, RNA, lipids, proteins, and small molecules. In this account, the structural similarity and differences of well-known Cys2His2-type zinc fingers such as zinc interaction factor 268 (ZIF268), transcription factor IIIA (TFIIIA), GAGA, and Ros will be explained. These proteins perform their specific roles in species from archaea to eukaryotes and they show significant structural similarity; however, their aligned amino acids present low sequence homology. These zinc finger proteins have different numbers of domains for their structural roles to maintain biological progress through transcriptional regulations from exogenous stresses. The superimposed structures of these finger domains provide interesting details when these fingers are applied to specific gene binding and editing. The structural information in this study will aid in the selection of unique types of zinc finger applications in vivo and in vitro approaches, because biophysical backgrounds including complex structures and binding affinities aid in the protein design area. PMID- 27713216 TI - In Vivo Wound Healing Activity of Crocodile (Crocodylus siamensis) Hemoglobin and Evaluation of Antibacterial and Antioxidant Properties of Hemoglobin and Hemoglobin Hydrolysate. AB - The hydrolysis of proteins constitutes an invaluable tool, granting access to a variety of peptide fragments with potentially interesting biological properties. Therefore, a hemoglobin (Hb) hydrolysate of Crocodylus siamensis was generated by digestion under acidic conditions. The antibacterial and antioxidant activities of the Hb hydrolysate were assessed in comparison with intact Hb. A disc diffusion assay revealed that the Hb hydrolysate exhibited antibacterial activity against eight strains of gram-positive bacteria and showed a higher efficacy than intact Hb. Moreover, the antioxidant activity of intact Hb and its hydrolysate was evaluated using ABTS and DPPH radical scavenging assays. The Hb hydrolysate exhibited free radical scavenging rates of 6-32%, whereas intact Hb showed a slightly higher activity. In addition, non-toxicity to human erythrocytes was observed after treatment with quantities of Hb hydrolysate up to 10 MUg. Moreover, active fragmented Hb (P3) was obtained after purifying the Hb hydrolysate by reversed-phase HPLC. Scanning electron microscopy demonstrated the induction of bacterial cell membrane abnormalities after exposure to P3. Antibacterial and antioxidant activities play crucial roles for supporting the wound healing activity. Consequently, an in vivo mice excisional skin wound healing assay was carried out to investigate the effects of intact Hb treatment on wound healing in more detail. The results clearly demonstrate that intact Hb is capable of promoting 75% wound closure within 6 days. These findings imply that intact Hb of C. siamensis and its acid hydrolysate may serve as valuable precursors for food supplementary products benefitting human health. PMID- 27713217 TI - The Predictive Value of Pathologic Features in Pituitary Adenoma and Correlation with Pituitary Adenoma Recurrence. AB - BACKGROUND: The 2004 World Health Organization classification introduced atypical pituitary adenoma (aPA), which was equivocally defined as invasion with increased mitotic activity that had a Ki-67 labeling index (LI) greater than 3%, and extensive p53 immunoreactivity. However, aPAs that exhibit all of these features are rare and the predictive value for recurrence in pituitary adenomas (PAs) remains uncertain. Thus, we sought to characterize pathological features of PAs that correlated with recurrence. METHODS: One hundred and sixty-seven cases of surgically resected PA or aPA were retrieved from 2011 to 2013 in Seoul St. Mary's Hospital. Among them, 28 cases were confirmed to be recurrent, based on pathologic or radiologic examination. The pathologic characteristics including mitosis, invasion, Ki-67 LI and p53 immunoreactivity were analyzed in relation to recurrence. RESULTS: Analysis of the pathologic features indicated that only Ki 67 LI over 3% was significantly associated with tumor recurrence (p = .02). The cases with at least one pathologic feature showed significantly higher recurrence rates (p < .01). Analysis indicated that cases with two pathologic features, Ki 67 LI over 3% and extensive p53 immunoreactivity 20% or more, were significantly associated with tumor recurrence (p < .01). CONCLUSIONS: Based on these results, PA tumor recurrence can be predicted by using mitosis, invasion, Ki-67 LI (3%), or extensive p53 immunoreactivity (>= 20%). Assessment of these features is recommended for PA diagnosis for more accurate prediction of recurrence. PMID- 27713218 TI - Resumed Publication of Pharmaceuticals in 2009. AB - After a five year hiatus, we are pleased to announce the resumption of publication of the MDPI journal Pharmaceuticals (ISSN 1424-8247). First launched in 2004, few suitable papers were submitted and only one was published [1], before our limited editorial resources at the time led us to temporarily discontinue publication. Several things have changed since then. First, there has been an explosive growth in the number of manuscripts submitted and published in MDPI's various current journals [2], whose topics clearly fall within the intended scope of Pharmaceuticals and we feel that these manuscripts merit a dedicated forum. Second, the expansion of MDPI, now with Editorial Offices and staff in Basel (Switzerland) and Beijing (China), allows us to provide Pharmaceuticals' authors with all the services they could desire and deserve: a simple manuscript submission process, rigorous peer review, quick revision turnaround, Open Access publication on a new and attractive platform and coverage by all the major abstracting services. In addition, a new Editorial Board comprised of noted academic and industry scientists has been set up for Pharmaceuticals. Finally, to better focus the subject matter published in Pharmaceuticals on molecular medicines, we have also set up a special section in International Journal of Molecular Sciences (IJMS, ISSN 1422-0067) for papers on nutraceuticals or chemopreventives. We look forward to receiving and publishing your papers and as always, we welcome your comments and suggestions. [...].

AB - Mastic gum is a viscous light-green liquid obtained from the bark of Pistacia lentiscus var. chia. which belongs to the Anacardiaceae family. The gum has been fractionated to investigate the antimicrobial activity of the whole gum and its fractions against various strains of Helicobacter pylori. The polymeric gum fraction was separated from the essential oil and the resin (trunk exudates without essential oil) to assess and compare the anti-H. pylori activity of the polymer fraction against lower molecular weight fractions, the gum itself and masticated gum. The polymer fraction was also oxidized and assessed for antimicrobial activity. PMID- 27713220 TI - Knowledge and Implementation of the New European Guide in the Management of Arterial Hypertension. The Cigema Survey. AB - Knowledge of guideline implementation pitfalls allows anticipation and solving of problems and may help to promote implementation. The aims of this study were: 1) to find out how much is known among medical professionals about the recommendations for the Management of Arterial Hypertension; 2) to study in depth the extent of implementation and 3) to evaluate the manner in which this guide will be applied to daily medical practice. The Delphi method was used for this work. The total estimated sample size was 2,250 physicians. The carefully selected experts answered questionnaires in two or more rounds. The final sample size was 2,475 physicians. Results of the study are detailed in the article. Among the resultsIt is noteworthy that the guide is viewed as needed among all those who have been interviewed and this agreement about its need is generalised and that the improvement in medical practice, together with individual treatment and cardiovascular risk stratification are viewed positively in opinions reached by consensus by the majority of physicians, regardless of whether they are specialists or general practitioners. The main results of this study emphasize the fact that physicians need a guideline for the management of hypertensive patients and that most of physicians agree with them. The new guidelines on arterial hypertension management are widely known among physicians and there appears to be a global agreement regarding the need for the implementation of the new recommendations. PMID- 27713221 TI - Antitumor Activity of Some Prenylated Xanthones. AB - Pyranoxanthones 6-8 were obtained by dehydrogenation of the respective dihydropyranoxanthones 3-5 with DDQ in dry dioxane. Two prenylated xanthones 10,11 were obtained from the reaction of 1-hydroxyxanthone (9) with prenyl bromide in alkaline medium, or by condensation of xanthone 9 with isoprene in the presence of orthophosphoric acid. The structural elucidation of the two new compounds 6,11, as well as an update of data for the already described prenylated derivatives 7,8,10 were accomplished by IR, UV, HRMS and NMR (1H, 13C, HSQC and HMBC) techniques. The effect of the prenylated xanthone derivatives on the in vitro growth of human tumor cell lines MCF-7 (breast adenocarcinoma) and NCI-H460 (non-small cell lung cancer) is also reported. Compounds 10 and 11 have been found to exhibit a moderate growth inhibitory activity against the MCF-7 cell line. PMID- 27713222 TI - Antihypertensive Drug and Inner Ear Perfusion: An Otologist's Point of View. AB - A number of labyrinthine disorders with sensorineural hearing loss, vertigo, and tinnitus are known to occur to young people without vascular risk factors, thus being classified as "idiopathic" in the absence of satisfactory explanations; in the last decade, this phenomenon has found a reliable explanation by the adverse effect of a sharp decrease of blood pressure values followed by an abnormal vasomotor regulation. This model may not only be applied to healthy subjects, but even had some confirmation in conditions possibly affecting hemodynamic changes, such as heart failure or treated hypertension. In particular, the results of a recent study on the impact of different antihypertensive therapies, which was analyzed by monitoring the onset or enhancement of tinnitus as a symptom of inner ear sufferance, unequivocally demonstrated an increased prevalence of tinnitus in subjects submitted to more "aggressive" treatments. This seems in agreement with recent observations about the model of fluid homeostasis of the inner ear, and suggests, when possible, to resort to treatments with modulatory effects in order to maintain a steady perfusion to the labyrinth thus protecting its function. PMID- 27713223 TI - Fusion of a Short HA2-Derived Peptide Sequence to Cell-Penetrating Peptides Improves Cytosolic Uptake, but Enhances Cytotoxic Activity. AB - Cell-penetrating peptides (CPP) have become a widely used tool for efficient cargo delivery into cells. However, one limiting fact is their uptake by endocytosis causing the enclosure of the CPP-cargo construct within endosomes. One often used method to enhance the outflow into the cytosol is the fusion of endosome-disruptive peptide or protein sequences to CPP. But, until now, no studies exist investigating the effects of the fusion peptide to the cellular distribution, structural arrangements and cytotoxic behaviour of the CPP. In this study, we attached a short modified sequence of hemagglutinin subunit HA2 to different CPP and analysed the biologic activity of the new designed peptides. Interestingly, we observed an increased cytosolic distribution but also highly toxic activities in the micromolar range against several cell lines. Structural analysis revealed that attachment of the fusion peptide had profound implications on the whole conformation of the peptide, which might be responsible for membrane interaction and endosome disruption. PMID- 27713224 TI - Hypertensive Emergency in Aortic Dissection and Thoracic Aortic Aneurysm-A Review of Management. AB - Over the last few decades, treatment for aortic dissection and thoracic aortic aneurysms has evolved significantly with improvement in outcomes. Treatment paradigms include medical, endovascular and surgical options. As aortic dissection presents as a hypertensive emergency, diligent control of BP is of utmost importance in order to reduce the progression of dissection with possible aortic branch malperfusion. Treatment should begin on arrival to the emergency department and continues in the intensive care unit, endovascular suite or the operating room. Novel antihypertensive medications with improved pharmacological profile and improved surgical techniques, have improved the prognosis of patients with aortic aneurysm and/or aortic dissection. Nevertheless, morbidity and mortality remain high and hypertensive emergency poses a significant challenge in aortic dissection and thoracic aortic aneurysms. PMID- 27713225 TI - A New Classification of Prodrugs: Regulatory Perspectives. AB - Many therapeutic agents are manufactured and administered in prodrug forms. In this paper, a new classification system for prodrugs is proposed to provide useful information about where in the body a prodrug is converted to the active drug. In this system, prodrugs are classified into Type I or Type II and the respective Subtypes IA, IB, IIA, IIB or IIC based on their sites of conversion into the final active drug form. For Type I prodrugs, conversion occurs intracellularly (e.g., antiviral nucleoside analogs, lipid-lowering statins), whereas conversion of Type II prodrugs occurs extracellularly, for examples in digestive fluids, systemic circulation or other extracellular body fluids (e.g., etoposide phosphate, valganciclovir, fosamprenavir). Type IA prodrugs refer to those that are converted at the cellular targets of therapeutic actions, whereas Type IB prodrugs' conversion occurs in the primary metabolic tissues such as liver, gut, or lung. For Type II prodrugs, the conversion process could either take place extracellularly in the milieu of gastrointestinal fluids (Type IIA), in the systemic circulation and/or other systemic extracellular fluid compartments (Type IIB), or near therapeutical target cells (Type IIC). A prodrug may belong to multiple categories and be recognized as a Mixed-Type prodrug. For example a prodrug may be converted both in target cells and metabolic tissues such as liver (i.e., named as a Type IA/IB prodrug), or one converted in both GI fluids and systemic circulations (i.e., named as a Type IIA/IIB prodrug). The Mixed-Type compound can be further distinguished as a Parallel Mixed-Type or Sequential Mixed-Type prodrug depending on the conversion processes that proceed with, either in concurrent or in sequential steps. Because traditional analysis of drug actions has always been focused on the site of action and mode of action, the proposed classification of prodrugs based on cellular locations of conversion is in line with current thought processes of regulatory review and risk assessment of both prodrug and active drug. By gaining insights regarding the site of action through prodrug nomenclature, risk benefit evaluation can be made more efficiently because both information on kinetics and impact of tissues involved are adequately revealed through prodrug subtype designated. In conclusion, the new system of classification will add to existing knowledge of prodrug classifications, and will provide improved insight into the contributory roles of both prodrug and active drug in the product's efficacy and safety, and their risk-benefit assessment. PMID- 27713226 TI - Obsessive-Compulsive and Post Traumatic Avoidance Symptoms Influence the Response to Antihypertensive Therapy: Relevance in Uncontrolled Hypertension. AB - AIM: To investigate the association of uncontrolled hypertension with psychological factors associated with high cardiovascular morbidity and mortality (type D personality, depression, posttraumatic stress-related symptoms). METHODS: 205 consecutive outpatient hypertensives completed three questionnaires evaluating Type D personality (DS 16), post traumatic symptoms (revised Impact of Events Scale), symptoms of anxiety, hostility, depression and obsessive compulsive traits (subscales of the Symptom Checklist). Uncontrolled hypertension was diagnosed when clinic sitting blood pressure was above 140/90 mmHg (130/80 in the presence of diabetes or nephropathy), despite reported adherence to treatment with at least three antihypertensive medications, including a diuretic. RESULTS: Uncontrolled hypertension (39%), was predicted by lower scores at Symptom Checklist obsessive-compulsive subscale and higher number of post traumatic avoidance symptoms, older age, diabetes, higher systolic pressure at first visit and longstanding hypertension. Type D personality correlated with depression, hostility, anxiety, compulsiveness, history of malignancy, and older age, but not with uncontrolled hypertension. CONCLUSIONS: Uncontrolled hypertension is associated with low obsessionality and avoidance symptoms, which reduce compliance to treatment. On the contrary, type D personality is not correlated with uncontrolled hypertension, as it includes compulsiveness, which improves compliance. A multidisciplinary approach to the hypertensive patient is mandatory to establish if the psychological profile affects compliance. PMID- 27713228 TI - Aliskiren: Just a New Drug for Few Selected Patients or an Innovative Molecule Predestinated to Replace Arbs and Ace-Inhibitors? AB - The renin-angiotensin-aldosterone system (RAAS) plays a dominant role in the pathophysiology of hypertension, diabetes mellitus, chronic kidney disease and chronic heart failure. Therefore, drugs that block key components of the RAAS such as ACE inhibitors (ACEI) and angiotensin receptor blockers (ARBs) have gained wide clinical use for these indications. Despite progress, the morbidity and mortality of patients treated with ACEI or ARBs remain high. Aliskiren (Tekturna, Rasilez) is the first orally active inhibitor of renin approved for clinical use as an antihypertensive agent. The development program has established that at the licensed doses of 150 mg and 300 mg. Aliskiren is effective either as monotherapy or in combination with drugs from the other major classes. In this review we analyze and review the information already gained with Aliskiren, raises questions regarding the advantages of DRIs as monotherapy compared to marketed ACEIs and ARBs, their potential added value in combination with other RAAS modulators and other still unproven benefits in relation to prorenin and renin receptor biology.

AB - BACKGROUND: Combination therapy with antihypertensive agents utilises different mechanisms of action and may be responsible for a more effective decrease in blood pressure. OBJECTIVE: To review the recently published trials on efficacy and safety of the combination therapy with olmesartan and amlodipine. RESULTS: The double-blind American COACH (Combination of Olmesartan Medoxomil and Amlopdine Besylate in Controlling High Blood Pressure) study (2008) showed in 1,940 patients that after eight weeks of treatment the BP goals were most frequently achieved in the 'combination therapy group', with 56.3% (54.1-58.5%) and 54.0% (51.8-56.2%) of patients reaching adequate blood pressure of.

AB - In the past several years a number of alterations in the PAFAH/PLA2G7/LpPLA2 gene have been described. These include inactivating mutations, polymorphisms in the coding region, and other genetic changes located in promoter and intronic regions of the gene. The consequences associated with these genetic variations have been evaluated from different perspectives, including in vitro biochemical and molecular studies and clinical analyses in human subjects. This review highlights the current state of the field and suggests new approaches that can be used to evaluate functional consequences associated with mutations and polymorphisms in the PAF-AH gene. PMID- 27713230 TI - Coenzyme Q10 and Neurological Diseases. AB - Coenzyme Q10 (CoQ10, or ubiquinone) is a small electron carrier of the mitochondrial respiratory chain with antioxidant properties. CoQ10 supplementation has been widely used for mitochondrial disorders. The rationale for using CoQ10 is very powerful when this compound is primary decreased because of defective synthesis. Primary CoQ10 deficiency is a treatable condition, so heightened "clinical awareness" about this diagnosis is essential. CoQ10 and its analogue, idebenone, have also been widely used in the treatment of other neurodegenerative disorders. These compounds could potentially play a therapeutic role in Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Friedreich's ataxia, and other conditions which have been linked to mitochondrial dysfunction. This article reviews the physiological roles of CoQ10, as well as the rationale and the role in clinical practice of CoQ10 supplementation in different neurological diseases, from primary CoQ10 deficiency to neurodegenerative disorders. PMID- 27713231 TI - Oxytocin: Old Hormone, New Drug. AB - Oxytocin (OT), traditionally associated with reproductive functions, was revisited recently, and several new functions in cardiovascular regulation were discovered. These functions include stimulation of the cardioprotective mediators nitric oxide (NO) and atrial natriuretic peptide. OT's cardiovascular outcomes comprise: (i) natriuresis, (ii) blood pressure reduction, (iii) negative inotropic and chronotropic effects, (iv) parasympathetic neuromodulation, (v) NO pathway involvement in vasodilatation and endothelial cell growth, (vi) anti inflammatory and (vii) antioxidant activities as well as (viii) metabolic effects. In addition, we have reported abundant OT in the early developing heart with its capacity to generate cardiomyocytes (CMs) from mouse embryonic stem cells and stem cells residing in the heart. OT increases glucose uptake by cultured CMs, in normal, hypoxic and even in insulin resistance conditions. In experimentally-induced myocardial infarction in rats, continuous in vivo OT delivery improves the cardiac healing process and cardiac work, diminishes inflammation, and stimulates angiogenesis. Therefore, in pathological situations, OT plays an anti-inflammatory and cardioprotective role, enhancing vascular and metabolic functions, with potential therapeutic application(s). PMID- 27713232 TI - Effect of Different Metal Ions on the Biological Properties of Cefadroxil. AB - The effect of different metal ions on the intestinal transport and the antibacterial activity of cefadroxil [(6R,7R)-7-{[(2R)-2-amino-2-(4 hydroxyphenyl)acetyl]amino}-3-methyl-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2 carboxylic acid] was investigated. The [14C]Gly-Sar uptake via PEPT1 was inhibited by Zn2+ and Cu2+ treatment in a concentration-dependent manner (Ki values 107 +/- 23 and 19 +/- 5 MUM, respectively). Kinetic analysis showed that the Kt of Gly-Sar uptake was increased 2-fold in the presence of zinc sulphate (150 MUM) whereas the Vmax value were not affected suggesting that zinc ions inhibited Gly-Sar uptake by PEPT1 in a competitively manner. Ni2+ exhibited moderate inhibitory effect, whereas Co2+, Mg2+, Al3+ ions showed no inhibitory effect on Gly-Sar uptake via PEPT1. Subsequently, we examined the effect of Zn2+ and Al3+ ions on the transepithelial transport of cefadroxil across Caco-2 cells cultured on permeable supports. The results showed that zinc ions inhibited the transepithelial flux of cefadroxil at Caco-2 cell monolayers while Al3+ ions had no effect. The interaction of cephalosporins with the metal ions could suggest negative effects of some metal ions on the clinical aspects of small intestinal peptide and drug transport. Finally, the effect of Zn2+, Cu2+ and Al3+ ions on the antibacterial activity of cefadroxil was tested. It was found that there is no significant difference between the activity of cefadroxil and the cefadroxil metal ion complexes studied against the investigated sensitive bacterial species. PMID- 27713233 TI - Resveratrol: An Antiaging Drug with Potential Therapeutic Applications in Treating Diseases. AB - The prevention of aging is one of the most fascinating areas in biomedicine. The first step in the development of effective drugs for aging prevention is a knowledge of the biochemical pathways responsible for the cellular aging process. In this context it seems clear that free radicals play a key role in the aging process. However, in recent years it has been demonstrated that the families of enzymes called sirtuins, specifically situin 1 (SIRT1), have an anti-aging action. Thus, the natural compound resveratrol is a natural compound that shows a very strong activation of SIRT1 and also shows antioxidant effects. By activating sirtuin 1, resveratrol modulates the activity of numerous proteins, including peroxisome proliferator-activated receptor coactivator-1alpha (PGC-1 alpha), the FOXO family, Akt (protein kinase B) and NFkappabeta. In the present review, we suggest that resveratrol may constitute a potential drug for prevention of ageing and for the treatment of several diseases due to its antioxidant properties and sirtuin activation.

PMID- 27713235 TI - The Soluble Epoxide Hydrolase Inhibitor AR9281 Decreases Blood Pressure, Ameliorates Renal Injury and Improves Vascular Function in Hypertension. AB - Soluble epoxide hydrolase inhibitors (sEHIs) are demonstrating promise as potential pharmaceutical agents for the treatment of cardiovascular disease, diabetes, inflammation, and kidney disease. The present study determined the ability of a first-inclass sEHI, AR9281, to decrease blood pressure, improve vascular function, and decrease renal inflammation and injury in angiotensin hypertension. Rats were infused with angiotensin and AR9281 was given orally during the 14-day infusion period. Systolic blood pressure averaged 180 +/- 5 mmHg in vehicle treated and AR9281 treatment significantly lowered blood pressure to 142 +/- 7 mmHg in angiotensin hypertension. Histological analysis demonstrated decreased injury to the juxtamedullary glomeruli. Renal expression of inflammatory genes was increased in angiotensin hypertension and two weeks of AR9281 treatment decreased this index of renal inflammation. Vascular function in angiotensin hypertension was also improved by AR9281 treatment. Decreased afferent arteriolar and mesenteric resistance endothelial dependent dilator responses were ameliorated by AR9281 treatment of angiotensin hypertensive rats. These data demonstrate that the first-in-class sEHI, AR9281, lowers blood pressure, improves vascular function and reduces renal damage in angiotensin hypertension.

AB - Three thermally and hydrolytically stable silylamide trioxanes have been prepared from the natural trioxane artemisinin in only five simple chemical steps and in at least 56% overall yield. Two of these new chemical entities completely cured malariainfected mice at a single oral dose of only 8 mg/kg combined with 24 mg/kg of mefloquine hydrochloride. The high efficacy of this ACT chemotherapy is considerably better than the efficacy using the popular trioxane drug artemether plus mefloquine hydrochloride. PMID- 27713237 TI - Real Time Imaging of Biomarkers in the Parkinson's Brain Using Mini-Implantable Biosensors. II. Pharmaceutical Therapy with Bromocriptine. AB - We used Neuromolecular Imaging (NMI) and trademarked BRODERICK PROBE(r) mini implantable biosensors, to selectively and separately detect neurotransmitters in vivo, on line, within seconds in the dorsal striatal brain of the Parkinson's Disease (PD) animal model. We directly compared our results derived from PD to the normal striatal brain of the non-Parkinson's Disease (non-PD) animal. This advanced biotechnology enabled the imaging of dopamine (DA), serotonin (5-HT), homovanillic acid (HVA) a metabolite of DA, L-tryptophan (L-TP) a precursor to 5 HT and peptides, dynorphin A 1-17 (Dyn A) and somatostatin (somatostatin releasing inhibitory factor) (SRIF). Each neurotransmitter and neurochemical was imaged at a signature electroactive oxidation/half-wave potential in dorsal striatum of the PD as compared with the non-PD animal. Both endogenous and bromocriptine-treated neurochemical profiles in PD and non-PD were imaged using the same experimental paradigm and detection sensitivities. Results showed that we have found significant neurotransmitter peptide biomarkers in the dorsal striatal brain of endogenous and bromocriptine-treated PD animals. The peptide biomarkers were not imaged in dorsal striatal brain of non-PD animals, either endogenously or bromocriptine-treated. These findings provide new pharmacotherapeutic strategies for PD patients. Thus, our findings are highly applicable to the clinical treatment of PD. PMID- 27713239 TI - Spironolactone Plus Full-Dose ACE Inhibition in Patients with Idiopathic Membranous Nephropathy and Nephrotic Syndrome: Does It Really Work? AB - We have studied the effects of add-on spironolactone treatment (100 mg/day) in 11 patients with idiopathic membranous nephropathy (IMN) and > 3 gm proteinuria/day despite angiotensin converting enzyme (ACE) inhibitor therapy titrated to a systolic/diastolic blood pressure < 120/80 mmHg. Blood pressure, 24-hour urinary protein excretion, and creatinine clearance were measured prior to, after two months of combined therapy, and after a 2-month withdrawal period of spironolactone. While systolic and diastolic blood pressure decreased significantly after spironolactone therapy, proteinuria did not improve. Serum potassium increased significantly as well, with three patients requiring resin binding therapy. Thus, spironolactone seems to have no additional antiproteinuric effects over ACE inhibitor therapy in patients with IMN and nephrotic syndrome and carries the risk of significant hyperkalemia. PMID- 27713240 TI - Hypersensitivity Reactions to Nonsteroidal Anti-Inflammatory Drugs: An Update. AB - After beta lactam antibiotics, hypersensitivity reactions to nonsteroidal antiinflammatory drugs are the second cause of hypersensitivity to drugs. Acute manifestations affect the respiratory tract (aspirin exacerbated respiratory disease), the skin (urticaria and angioedema), or are generalized (anaphylaxis). Correct diagnosis and treatment in order to prevent unnecessary morbidity and the potential risk of death from these severe reactions, and to provide proper medical advice on future drug use frequently requires the participation of allergology specialists familiar with these clinical conditions. PMID- 27713242 TI - Role of Glycogen Synthase Kinase-3beta in APP Hyperphosphorylation Induced by NMDA Stimulation in Cortical Neurons. AB - The phosphorylation of Amyloid Precursor Protein (APP) at Thr668 plays a key role in APP metabolism that is highly relevant to AD. The c-Jun-N-terminal kinase (JNK), glycogen synthase kinase-3beta (GSK-3beta) and cyclin-dependent kinase 5 (Cdk5) can all be responsible for this phosphorylation. These kinases are activated by excitotoxic stimuli fundamental hallmarks of AD. The exposure of cortical neurons to a high dose of NMDA (100 MUM) for 30'-45' led to an increase of P-APP Thr668. During NMDA stimulation APP hyperphosphorylation has to be assigned to GSK-3beta activity, since addition of L803-mts, a substrate competitive inhibitor of GSK-3beta reduced APP phosphorylation induced by NMDA. On the contrary, inhibition of JNK and Cdk5 with D-JNKI1 and Roscovitine respectively did not prevent NMDA-induced P-APP increase. These data show a tight connection, in excitotoxic conditions, between APP metabolism and the GSK-3beta signaling pathway. PMID- 27713241 TI - The Timing of Antidepressant Effects: A Comparison of Diverse Pharmacological and Somatic Treatments. AB - Currently available antidepressants used to treat major depressive disorder (MDD) unfortunately often take weeks to months to achieve their full effects, commonly resulting in considerable morbidity and increased risk for suicidal behavior. Our lack of understanding of the precise cellular underpinnings of this illness and of the mechanism of action of existing effective pharmacological treatments is a large part of the reason that therapies with a more rapid onset of antidepressant action (ROAA) have not been developed. Other issues that need to be addressed include heterogeneous clinical concepts and statistical models to measure rapid antidepressant effects. This review describes the timing of onset of antidepressant effects for various therapies used to treat MDD. While several agents produce earlier improvement of depressive symptoms (defined as occurring within one week), the response rate associated with such agents can be quite variable. These agents include both currently available antidepressants as well as other pharmacological and non-pharmacological interventions. Considerably fewer treatments are associated with ROAA, defined as occurring within several hours or one day. Treatment strategies for MDD whose sustained antidepressant effects manifest within hours or even a few days would have an enormous impact on public health. PMID- 27713244 TI - Comparison of Functional Protein Transduction Domains Using the NEMO Binding Domain Peptide. AB - Protein transduction domains (PTDs), both naturally occurring and synthetic, have been extensively utilized for intracellular delivery of biologically active molecules both in vitro and in vivo. However, most comparisons of transduction efficiency have been performed using fluorescent markers. To compare efficiency of functional protein transduction, a peptide derived from IkB kinase beta (IKKbeta) that prevents formation of an active IKK complex was used as a biologically active cargo. This peptide, termed NEMO Binding Domain (NBD), is able to block activation of the transcriptional factor NF-kappaB by IKK, but not basal NF-kappaB activity. Our results demonstrate that Antp and Tat PTDs were most effective for delivery of NBD for inhibition of NF-kB activation compared to other PTD-NBD in both Hela and 293 cells, however, at higher concentrations (100 uM), the Antp-NBD as well as the FGF-NBD peptide caused significant cellular toxicity. In contrast to the cell culture results, delivery of NBD using 8K (octalysine) and 6R (six arginine) were the most effect in blocking inflammation following local, footpad delivery in a KLH-induced DTH murine model of inflammatory arthritis. These results demonstrate differences between PTDs for delivery of a functional cargo between cell types. PMID- 27713238 TI - Insulin and Insulin-Sensitizing Drugs in Neurodegeneration: Mitochondria as Therapeutic Targets. AB - Insulin, besides its glucose lowering effects, is involved in the modulation of lifespan, aging and memory and learning processes. As the population ages, neurodegenerative disorders become epidemic and a connection between insulin signaling dysregulation, cognitive decline and dementia has been established. Mitochondria are intracellular organelles that despite playing a critical role in cellular metabolism are also one of the major sources of reactive oxygen species. Mitochondrial dysfunction, oxidative stress and neuroinflammation, hallmarks of neurodegeneration, can result from impaired insulin signaling. Insulin sensitizing drugs such as the thiazolidinediones are a new class of synthetic compounds that potentiate insulin action in the target tissues and act as specific agonists of the peroxisome proliferator-activated receptor gamma (PPAR gamma). Recently, several PPAR agonists have been proposed as novel and possible therapeutic agents for neurodegenerative disorders. Indeed, the literature shows that these agents are able to protect against mitochondrial dysfunction, oxidative damage, inflammation and apoptosis. This review discusses the role of mitochondria and insulin signaling in normal brain function and in neurodegeneration. Furthermore, the potential protective role of insulin and insulin sensitizers in Alzheimer's, Parkinson's and Huntington's diseases and amyotrophic lateral sclerosis will be also discussed. PMID- 27713246 TI - Impact of Glycosylation on Effector Functions of Therapeutic IgG. AB - Human IgG has only one conserved glycosylation site located in the Cgamma2 domain of the Fc region that accounts for the presence of two sugar moieties per IgG. These IgG sugar cores play a critical role in a number of IgG effector functions. In the present review, we describe the main characteristics of IgG Fc glycosylation and some abnormalities of serum IgG glycosylation. We also discuss how glycosylation impacts on monoclonal antibodies (mAbs) and IVIg effector functions and how these molecules can be engineered. Several therapeutic antibodies have now been engineered to be no- or low-fucose antibodies and are currently tested in clinical trials. They exhibit an increased binding to activating FcgammaRIIIA and trigger a strong antibody-dependent cell cytotoxicity (ADCC) as compared to their highly-fucosylated counterparts. They represent a new generation of therapeutic antibodies that are likely to show a better clinical efficacy in patients, notably in cancer patients where cytotoxic antibodies are needed. PMID- 27713245 TI - Approved and Off-Label Uses of Obesity Medications, and Potential New Pharmacologic Treatment Options. AB - Available anti-obesity pharmacotherapy options remain very limited and development of more effective drugs has become a priority. The potential strategies to achieve weight loss are to reduce energy intake by stimulating anorexigenic signals or by blocking orexigenic signals, and to increase energy expenditure. This review will focus on approved obesity medications, as well as potential new pharmacologic treatment options. PMID- 27713249 TI - A New Baroreceptor Sensitivity-Restoring Ca-Channel Blocker Diminishes Age Related Morning Blood Pressure Increase in Hypertensive Patients: Open-Label Monitoring of Azelnidipine Treatment for Hypertension in the Early Morning (At HOME) Study. AB - BACKGROUND: Morning blood pressure (BP) surge, which exhibits an age-related increase, is a risk factor for stroke in elderly hypertensive patients, independently of the 24-h BP level. We studied the effect of the new baroreceptor sensitivity (BRS)-restoring Ca-channel blocker (CCB) azelnidipine (AZ) on this age-related morning BP increase. METHODS: We conducted a 16-week prospective study to clarify the effect of morning dosing of AZ on home BPs measured in the morning and in the evening in 2,546 hypertensive patients (mean age, 65.1 years; female, 53.6%). RESULTS: At baseline, ME-Dif (morning systolic BP [SBP]-evening SBP) increased with age, independently of ME-Ave (average of the morning and evening SBPs). This age-related increase of ME-Dif was exaggerated by regular alcohol drinking and beta-blocker use. After AZ treatment (14.3 +/- 3.6 mg/day), ME-AV and ME-Dif were significantly reduced independently of each other, with reductions of -18.1 +/- 15.6 and -2.5 +/- 13.2 mmHg, respectively (both p < 0.001). AZ treatment decreased age-related increase in ME-Dif particularly in patients who were regular consumers of alcohol and in beta-blocker users. CONCLUSIONS: The new BRS-restoring CCB AZ significantly reduced age-related increase in morning BP and had some potential benefit on cardiovascular protection in hypertension, particularly in elderly patients and/or consumers of alcohol. PMID- 27713243 TI - A Novel Category of Anti-Hypertensive Drugs for Treating Salt-Sensitive Hypertension on the Basis of a New Development Concept. AB - Terrestrial animals must conserve water and NaCl to survive dry environments. The kidney reabsorbs 95% of the sodium filtered from the glomeruli before sodium reaches the distal connecting tubules. Excess sodium intake requires the renal kallikrein-kinin system for additional excretion. Renal kallikrein is secreted from the distal connecting tubule cells of the kidney, and its substrates, low molecular kininogen, from the principal cells of the cortical collecting ducts (CD). Formed kinins inhibit reabsorption of NaCl through bradykinin (BK)-B2 receptors, localized along the CD. Degradation pathway of BK by kinin-destroying enzymes in urine differs completely from that in plasma, so that ACE inhibitors are ineffective. Urinary BK is destroyed mainly by a carboxypeptidase-Y-like exopeptidase (CPY) and partly by a neutral endopeptidase (NEP). Inhibitors of CPY and NEP, ebelactone B and poststatin, respectively, were found. Renal kallikrein secretion is accelerated by potassium and ATP-sensitive potassium (KATP) channel blockers, such as PNU-37883A. Ebelactone B prevents DOCA-salt hypertension in rats. Only high salt intake causes hypertension in animals deficient in BK-B2 receptors, tissue kallikrein, or kininogen. Hypertensive patients, and spontaneously hypertensive rats, excrete less kallikrein than normal subjects, irrespective of races, and become salt-sensitive. Ebelactone B, poststatin, and KATP channel blockers could become novel antihypertensive drugs by increase in urinary kinin levels. Roles of kinin in cardiovascular diseases were discussed. PMID- 27713248 TI - Effects of Adaptogens on the Central Nervous System and the Molecular Mechanisms Associated with Their Stress-Protective Activity. AB - Adaptogens were initially defined as substances that enhance the "state of nonspecific resistance" in stress, a physiological condition that is linked with various disorders of the neuroendocrine-immune system. Studies on animals and isolated neuronal cells have revealed that adaptogens exhibit neuroprotective, anti-fatigue, antidepressive, anxiolytic, nootropic and CNS stimulating activity. In addition, a number of clinical trials demonstrate that adaptogens exert an anti-fatigue effect that increases mental work capacity against a background of stress and fatigue, particularly in tolerance to mental exhaustion and enhanced attention. Indeed, recent pharmacological studies of a number of adaptogens have provided a rationale for these effects also at the molecular level. It was discovered that the stress-protective activity of adaptogens was associated with regulation of homeostasis via several mechanisms of action, which was linked with the hypothalamic-pituitary-adrenal axis and the regulation of key mediators of stress response, such as molecular chaperons (e.g., HSP70), stress-activated c Jun N-terminal protein kinase 1 (JNK1), Forkhead box O (FOXO) transcription factor DAF-16, cortisol and nitric oxide. PMID- 27713247 TI - Oxidative Stress Induced Mitochondrial Failure and Vascular Hypoperfusion as a Key Initiator for the Development of Alzheimer Disease. AB - Mitochondrial dysfunction may be a principal underlying event in aging, including age-associated brain degeneration. Mitochondria provide energy for basic metabolic processes. Their decay with age impairs cellular metabolism and leads to a decline of cellular function. Alzheimer disease (AD) and cerebrovascular accidents (CVAs) are two leading causes of age-related dementia. Increasing evidence strongly supports the theory that oxidative stress, largely due to reactive oxygen species (ROS), induces mitochondrial damage, which arises from chronic hypoperfusion and is primarily responsible for the pathogenesis that underlies both disease processes. Mitochondrial membrane potential, respiratory control ratios and cellular oxygen consumption decline with age and correlate with increased oxidant production. The sustained hypoperfusion and oxidative stress in brain tissues can stimulate the expression of nitric oxide synthases (NOSs) and brain endothelium probably increase the accumulation of oxidative stress products, which therefore contributes to blood brain barrier (BBB) breakdown and brain parenchymal cell damage. Determining the mechanisms behind these imbalances may provide crucial information in the development of new, more effective therapies for stroke and AD patients in the near future. PMID- 27713250 TI - Quercetin: A Treatment for Hypertension?-A Review of Efficacy and Mechanisms. AB - Quercetin is a polyphenolic flavonoid. Common sources in the diet are apples, onions, berries, and red wine. Epidemiological studies have found an inverse relationship between dietary quercetin intake and cardiovascular disease. This has led to in vitro, in vivo, and clinical research to determine the mechanism by which quercetin exerts cardioprotective effects. Recent studies have found a reduction in blood pressure when hypertensive (>140 mm Hg systolic and >90 mm Hg diastolic) animals and humans are supplemented with quercetin. Proposed mechanisms for the antihypertensive effect of quercetin include decreased oxidative stress, inhibition of angiotensin converting enzyme activity, improved endothelial function, direct action on the vascular smooth muscle, and/or modulation in cell signaling and gene expression. Although in vitro and in vivo evidence exists to support and refute each possibility, it is likely that quercetin influences multiple targets via a combination of known and as yet undiscovered mechanisms. The purpose of this review is to examine the mechanisms whereby quercetin might reduce blood pressure in hypertensive individuals. PMID- 27713251 TI - Antihypertensive Peptides from Milk Proteins. AB - Dietary proteins possess a wide range of nutritional and functional properties. They are used as a source of energy and amino acids, which are needed for growth and development. Many dietary proteins, especially milk proteins, contain physiologically active peptides encrypted in the protein sequence. These peptides may be released during gastrointestinal digestion or food processing and once liberated, cause different physiological functions. Milk-derived bioactive peptides are shown to have antihypertensive, antimicrobial, immunomodulatory, antioxidative and mineral-binding properties. During the fermentation of milk with certain lactobacilli, two interesting tripeptides Ile-Pro-Pro and Val-Pro Pro are released from casein to the final product. These lactotripeptides have attenuated the development of hypertension in several animal models and lowered blood pressure in clinical studies. They inhibit ACE in vitro at micromolar concentrations, protect endothelial function in vitro and reduce arterial stiffness in humans. Thus, milk as a traditional food product can after certain processing serve as a functional food and carry specific health-promoting effects, providing an option to control blood pressure. PMID- 27713252 TI - Monoclonal Antibodies for Systemic Lupus Erythematosus (SLE). AB - A number of monoclonal antibodies (mAb) are now under investigation in clinical trials to assess their potential role in Systemic Lupus Erythematosus (SLE). The most frequently used mAb is rituximab, which is directed against CD20, a membrane protein expressed on B lymphocytes. Uncontrolled trials reported an improvement of SLE activity in non-renal patients and other studies even reported an improvement of severe lupus nephritis unresponsive to conventional treatments. However two randomized trials failed to show the superiority of rituximab over conventional treatment in non renal SLE and in lupus nephritis. Preliminary trials reported promising results with epratuzumab, a humanized mAb directed against CD22, and with belimumab, a human mAb that specifically recognizes and inhibits the biological activity of BLyS a cytokine of the tumornecrosis-factor (TNF) ligand superfamily. Other clinical trials with mAb directed against TNF alpha, interleukin-10 (Il-10), Il-6, CD154, CD40 ligand, IL-18 or complement component C5 are under way. At present, however, in spite of good results reported by some studies, no firm conclusion on the risk-benefit profile of these mAbs in patients with SLE can be drawn from the available studies. PMID- 27713256 TI - Structural Examination of 6-Methylsulphonylphenanthro- [9,10-C]-furan-1(3H)-one-A Rofecoxib Degradation Product. AB - In the attempt to discover a new polymorph of rofecoxib (Vioxx(r)), an unexpected product resulted. The product was characterised by chemical composition, thermal behaviour and structure and found to be 6-methylsulphonylphenanthro-[9,10-C] furan-1(3H)-one, a photo-cyclization degradation product of rofecoxib. This is a significant finding because it indicates that without appropriate control of the recrystallisation procedures, the structural integrity of rofecoxib may be seriously compromised. PMID- 27713254 TI - Oromucosal Administration of Interferon to Humans. AB - The prevailing dogma is that, to be systemically effective, interferon-alpha (IFNalpha) must be administered in sufficiently high doses to yield functional blood concentrations. Such an approach to IFNa therapy has proven effective in some instances, but high-dose parenteral IFNalpha therapy has the disadvantage of causing significant adverse events. Mounting evidence suggests that IFNalpha delivered into the oral cavity in low doses interacts with the oral mucosa in a unique manner to induce systemic host defense mechanisms without IFNalpha actually entering the circulation, thus reducing the potential for toxic side effects. A better understanding of the applications and potential benefits of this treatment modality are under active investigation. This paper provides a review of the relevant literature on the clinical use of the oromucosal route of administration of interferon, with an emphasis on the treatment of influenza. PMID- 27713255 TI - Olesoxime (TRO19622): A Novel Mitochondrial-Targeted Neuroprotective Compound. AB - Olesoxime (TRO19622) is a novel mitochondrial-targeted neuroprotective compound undergoing a pivotal clinical efficacy study in Amyotrophic Lateral Sclerosis (ALS) and also in development for Spinal Muscular Atrophy (SMA). It belongs to a new family of cholesterol-oximes identified for its survival-promoting activity on purified motor neurons deprived of neurotrophic factors. Olesoxime targets proteins of the outer mitochondrial membrane, concentrates at the mitochondria and prevents permeability transition pore opening mediated by, among other things, oxidative stress. Olesoxime has been shown to exert a potent neuroprotective effect in various in vitro and in vivo models. In particular olesoxime provided significant protection in experimental animal models of motor neuron disorders and more particularly ALS. Olesoxime is orally active, crosses the blood brain barrier, and is well tolerated. Collectively, its pharmacological properties designate olesoxime as a promising drug candidate for motor neuron diseases. PMID- 27713253 TI - Nitric Oxide Synthase Inhibitors as Antidepressants. AB - Affective and anxiety disorders are widely distributed disorders with severe social and economic effects. Evidence is emphatic that effective treatment helps to restore function and quality of life. Due to the action of most modern antidepressant drugs, serotonergic mechanisms have traditionally been suggested to play major roles in the pathophysiology of mood and stress-related disorders. However, a few clinical and several pre-clinical studies, strongly suggest involvement of the nitric oxide (NO) signaling pathway in these disorders. Moreover, several of the conventional neurotransmitters, including serotonin, glutamate and GABA, are intimately regulated by NO, and distinct classes of antidepressants have been found to modulate the hippocampal NO level in vivo. The NO system is therefore a potential target for antidepressant and anxiolytic drug action in acute therapy as well as in prophylaxis. This paper reviews the effect of drugs modulating NO synthesis in anxiety and depression. PMID- 27713257 TI - Cell Permeable Peptides: A Promising Tool to Deliver Neuroprotective Agents in the Brain. AB - The inability of most drugs to cross the blood-brain barrier and/or plasma membrane limits their use for biomedical applications in the brain. Cell Permeable Peptides (CPPs) overcome this problem and are effective in vivo, crossing the plasma membrane and the blood-brain barrier. CPPs deliver a wide variety of compounds intracellularly in an active form. In fact, many bioactive cargoes have neuroprotective properties, and due to their ability to block protein-protein interactions, offer exciting perspectives in the clinical setting. In this review we give an overview of the Cell Permeable Peptides strategy to deliver neuroprotectants against neurodegeneration in the CNS. PMID- 27713258 TI - Renal Side Effects of Non-Steroidal Anti-Inflammatory Drugs in Neonates. AB - Non-steroidal anti-inflammatory drugs like ibuprofen or indomethacin are commonly prescribed drugs to induce pharmacologic closure of a patent ductus arteriosus in preterm neonates. Based on a recently published Cochrane meta-analysis, both drugs are equally effective to induce closure. Drug choice can therefore be based on differences in side effects or pharmaco-economic arguments. The current review quantifies the negative impact of either ibuprofen or indomethacin on renal function, including diuresis, glomerular filtration rate and renal tubular function. Both ibuprofen and indomethacin have a quantifiable impact on renal function. However, compared to ibuprofen, the negative impact of indomethacin is more pronounced. PMID- 27713259 TI - Deregulation of Interferon Signaling in Malignant Cells. AB - Interferons (IFNs) are a family of cytokines with potent antiproliferative, antiviral, and immunomodulatory properties. Much has been learned about IFNs and IFN-activated signaling cascades over the last 50 years. Due to their potent antitumor effects in vitro and in vivo, recombinant IFNs have been used extensively over the years, alone or in combination with other drugs, for the treatment of various malignancies. This review summarizes the current knowledge on IFN signaling components and pathways that are deregulated in human malignancies. The relevance of deregulation of IFN signaling pathways in defective innate immune surveillance and tumorigenesis are discussed. PMID- 27713260 TI - Home and Office Blood Pressure Control among Treated Hypertensive Patients in Japan: Findings from the Japan Home versus Office Blood Pressure Measurement Evaluation (J-HOME) Study. AB - Appropriate control of blood pressure (BP) is essential for prevention of future cardiovascular events. However, BP control among treated hypertensive patients has been insufficient. Recently, the usefulness of self-measured BP at home (home BP measurement) for the management of hypertension has been reported in many studies. We evaluated BP control both at home and in the office among treated hypertensive patients in primary care settings in Japan (the J-HOME study). We found poor control of home and office BPs and clarified some factors affecting control. We also examined factors associated with the magnitude of the white-coat effect, the morning-evening BP difference, and home heart rate in this J-HOME study. PMID- 27713262 TI - Degradation of Methyldopa by Banana. AB - Methyldopa, an antihypertensive, is a very close analogue of DOPA. Drug interaction accompanied by degradation in a banana juice mixture was reported for DOPA. However, the effect of banana on methyldopa has not been reported. Therefore, we have investigated the impact of banana juice on methyldopa. The drug and supernatant of banana pulp were mixed, and the mixture was observed for changes in color, drug concentration, and ultraviolet-visible absorption spectra at 30 degrees C. The originally clear and colorless mixture started to acquire a yellow coloration after about 30 seconds after the mixing. The color tone increasingly deepened, then blistered solid particles that do not dissolve were observed after 3 hours. Concentration of methyldopa in the mixture decreased by 60% after 5 min, to 0.5% after 30 min of the mixing. From these findings, it was suggested that the drastic alterations were caused by banana polyphenol oxidase that plays a role in the biosynthesis of melanin pigment from levodopa in banana pulp. Because the degradation of methyldopa occurs extremely fast, it was suggested concomitant use of this anti-hypertensive and banana juice consumption should be avoided in clinical practice. PMID- 27713261 TI - The Vasohibin Family. AB - Angiogenesis is regulated by the local balance between angiogenesis stimulators and inhibitors. A number of endogenous angiogenesis inhibitors have been found in the body. The origin of these inhibitors is mostly extrinsic to the vasculature. Recently, however, vascular endothelial cells themselves have been found to produce angiogenesis inhibitors including vasohibin-1. These intrinsic inhibitors are thought to regulate angiogenesis by an auto-regulatory or negative-feedback mechanism. This review will focus on vasohibin-1 produced by vascular endothelial cells and on its homologue, vasohibin-2. PMID- 27713263 TI - Cell-Penetrating Peptides for Antiviral Drug Development. AB - Viral diseases affect hundreds of millions of people worldwide, and the few available drugs to treat these diseases often come with limitations. The key obstacle to the development of new antiviral agents is their delivery into infected cells in vivo. Cell-penetrating peptides (CPPs) are short peptides that can cross the cellular lipid bilayer with the remarkable capability to shuttle conjugated cargoes into cells. CPPs have been successfully utilized to enhance the cellular uptake and intracellular trafficking of antiviral molecules, and thereby increase the inhibitory activity of potential antiviral proteins and oligonucleotide analogues, both in cultured cells and in animal models. This review will address the notable findings of these studies, highlighting some promising results and discussing the challenges CPP technology has to overcome for further clinical applications. PMID- 27713264 TI - Generic Medicine Pricing Policies in Europe: Current Status and Impact. AB - Generic medicine pricing is an area of national responsibility of European Union countries. This article aims to present the current status and impact of generic medicine pricing policies in ambulatory care in Europe. The study conducts a literature review of policies relating to free-pricing systems, price-regulated systems, price differentiation, price competition and discounts, and tendering procedures; and a survey of European generic medicine pricing policies. Competition from Indian generic medicine manufacturers, European variation in generic medicine prices and competition between generic medicine manufacturers by discount suggest that the potential savings to health care payers and patients from generic medicines are not fully realized in Europe. One way of attaining these savings may be to move away from competition by discount to competition by price. Free-pricing systems may drive medicine prices downwards under specific conditions. In price-regulated systems, regulation may lower prices of originator and generic medicines, but may also remove incentives for additional price reductions beyond those imposed by regulation. To date, little is known about the current status and impact of tendering procedures for medicines in ambulatory care. In conclusion, the European experience suggests that there is not a single approach towards developing generic medicine pricing policies in Europe. PMID- 27713267 TI - Molecular Model of Plasma PAF Acetylhydrolase-Lipoprotein Association: Insights from the Structure. AB - Plasma platelet-activating factor acetylhydrolase (PAF-AH), also called lipoprotein-associated phospholipase A2 (Lp-PLA2), is a group VIIA PLA2 enzyme that catalyzes the hydrolysis of PAF and certain oxidized phospholipids. Although the role of PAF-AH as a pro- or anti-atherosclerotic enzyme is highly debated, several studies have shown it to be an independent marker of cardiovascular diseases. In humans the majority of plasma PAF-AH is bound to LDL and a smaller portion to HDL; the majority of the enzyme being associated with small dense LDL and VHDL-1 subclasses. Several studies suggest that the anti- or pro atherosclerotic tendency of PAF-AH might be dependent on the type of lipoprotein it is associated with. Amino acid residues in PAF-AH necessary for binding to LDL and HDL have been identified. However our understanding of the interaction of PAF AH with LDL and HDL is still incomplete. In this review we present an overview of what is already known about the interaction of PAF-AH with lipoprotein particles, and we pose questions that are yet to be answered. The recently solved crystal structure of PAF-AH, along with functional work done by others is used as a guide to develop a model of interaction of PAF-AH with lipoprotein particles. PMID- 27713266 TI - Inhaled Corticosteroids. AB - Inhaled corticosteroids (ICS) are the most effective controllers of asthma. They suppress inflammation mainly by switching off multiple activated inflammatory genes through reversing histone acetylation via the recruitment of histone deacetylase 2 (HDAC2). Through suppression of airway inflammation ICS reduce airway hyperresponsiveness and control asthma symptoms. ICS are now first-line therapy for all patients with persistent asthma, controlling asthma symptoms and preventing exacerbations. Inhaled long-acting beta2-agonists added to ICS further improve asthma control and are commonly given as combination inhalers, which improve compliance and control asthma at lower doses of corticosteroids. By contrast, ICS provide much less clinical benefit in COPD and the inflammation is resistant to the action of corticosteroids. This appears to be due to a reduction in HDAC2 activity and expression as a result of oxidative stress. ICS are added to bronchodilators in patients with severe COPD to reduce exacerbations. ICS, which are absorbed from the lungs into the systemic circulation, have negligible systemic side effects at the doses most patients require, although the high doses used in COPD has some systemic side effects and increases the risk of developing pneumonia. PMID- 27713268 TI - NSAIDs and Acute Pancreatitis: A Systematic Review. AB - The resulting pain is the main symptom of acute pancreatitis and it should be alleviated as soon as possible. NSAIDs are the first line therapy for pain and they are generally administered to acute pancreatitis patients upon admission to the hospital. In addition, these drugs have also been used to prevent post endoscopic cholangiopancreatography (ERCP) acute pancreatitis. On the other hand, there are several reports indicating that NSAIDs may be the actual cause of acute pancreatitis. We carried out a literature search on PubMed/MEDLINE; all full text papers published in from January 1966 to November 2009 on the use of NSAIDs in acute pancreatitis were collected; the literature search was also supplemented by a review of the bibliographies of the papers evaluated. Thus, in this article, we will systematically review the current literature in order to better illustrate the role of NSAIDs in acute pancreatitis, in particular: i) NSAIDs as a cause of acute pancreatitis; ii) their use to prevent post-retrograde ERCP pancreatitis and iii) their efficacy for pain relief in the acute illness of the pancreas. PMID- 27713271 TI - Distribution of CPP-Protein Complexes in Freshly Resected Human Tissue Material. AB - Interest in cell-penetrating peptides (CPPs) as delivery agents has fuelled a large number of studies conducted on cultured cells and in mice. However, only a few studies have been devoted to the behaviour of CPPs in human tissues. Therefore, we performed ex vivo tissue-dipping experiments where we studied the distribution of CPP-protein complexes in samples of freshly harvested human tissue material. We used the carcinoma or hyperplasia-containing specimens of the uterus and the cervix, obtained as surgical waste from nine hysterectomies. Our aim was to evaluate the tissue of preference (epithelial versus muscular/connective tissue, carcinoma versus adjacent histologically normal tissue) for two well-studied CPPs, the transportan and the TAT-peptide. We complexed biotinylated CPPs with avidin-?-galactosidase (ABG), which enabled us to apply whole-mount X-gal staining as a robust detection method. Our results demonstrate that both peptides enhanced the tissue distribution of ABG. The enhancing effect of the tested CPPs was more obvious in the normal tissue and in some specimens we detected a striking selectivity of CPP-ABG complexes for the normal tissue. This unexpected finding encourages the evaluation of CPPs as local delivery agents in non-malignant situations, for example in the intrauterine gene therapy of benign gynaecological diseases. PMID- 27713270 TI - Targeting the Tumour: Cell Penetrating Peptides for Molecular Imaging and Radiotherapy. AB - Over the last couple of years, the number of original papers and reviews discussing various applications of cell penetrating peptides (CPPs) has grown exponentially. This is not remarkable since CPPs are capable of transporting the most varying cargo across cell membranes which is one of the biggest problems in drug delivery and targeted therapy. In this review, we focus on the use of CPPs and related peptides for delivery of imaging contrast agents and radionuclides to cells and tissues with the ultimate goal of in vivo molecular imaging and molecular radiotherapy of intracellular and even intranuclear targets. PMID- 27713269 TI - Platelet-Derived Growth Factor (PDGF)/PDGF Receptors (PDGFR) Axis as Target for Antitumor and Antiangiogenic Therapy. AB - Angiogenesis in normal and pathological conditions is a multi-step process governed by positive and negative endogenous regulators. Many growth factors are involved in different steps of angiogenesis, like vascular endothelial growth factors (VEGF), fibroblast growth factor (FGF)-2 or platelet-derived growth factors (PDGF). From these, VEGF and FGF-2 were extensively investigated and it was shown that they significantly contribute to the induction and progression of angiogenesis. A lot of evidence has been accumulated in last 10 years that supports the contribution of PDGF/PDGFR axis in developing angiogenesis in both normal and tumoral conditions. The crucial role of PDGF-B and PDGFR-beta in angiogenesis has been demonstrated by gene targeting experiments, and their expression correlates with increased vascularity and maturation of the vascular wall. PDGF and their receptors were identified in a large variety of human tumor cells. In experimental models it was shown that inhibition of PDGF reduces interstitial fluid pressure in tumors and enhances the effect of chemotherapy. PDGFR have been involved in the cardiovascular development and their loss leads to a disruption in yolk sac blood vessels development. PDGFRbeta expression by pericytes is necessary for their recruitment and integration in the wall of tumor vessels. Endothelial cells of tumor-associated blood vessels can express PDGFR. Based on these data, it was suggested the potential benefit of targeting PDGFR in the treatment of solid tumors. The molecular mechanisms of PDGF/PDGFR-mediated angiogenesis are not fully understood, but it was shown that tyrosine kinase inhibitors reduce tumor growth and angiogenesis in experimental xenograft models, and recent data demonstrated their efficacy in chemoresistant tumors. The in vivo effects of PDGFR inhibitors are more complex, based on the cross-talk with other angiogenic factors. In this review, we summarize data regarding the mechanisms and significance of PDGF/PDGFR expression in normal conditions and tumors, focusing on this axis as a potential target for antitumor and antiangiogenic therapy. PMID- 27713265 TI - The Chick Embryo Chorioallantoic Membrane as an In Vivo Assay to Study Antiangiogenesis. AB - Antiangiogenesis, e.g., inhibition of blood vessel growth, is being investigated as a way to prevent the growth of tumors and other angiogenesis-dependent diseases. Pharmacological inhibition interferes with the angiogenic cascade or the immature neovasculature with synthetic or semi-synthetic substances, endogenous inhibitors or biological antagonists.The chick embryo chorioallantoic membrane (CAM) is an extraembryonic membrane, which serves as a gas exchange surface and its function is supported by a dense capillary network. Because its extensive vascularization and easy accessibility, CAM has been used to study morphofunctional aspects of the angiogenesis process in vivo and to study the efficacy and mechanism of action of pro- and anti-angiogenic molecules. The fields of application of CAM in the study of antiangiogenesis, including our personal experience, are illustrated in this review article. PMID- 27713273 TI - Hybridoma-Derived Idiotype Vaccine for Lymphoma: Approval Must Wait. AB - Hybridoma-derived idiotype vaccines have been used for the experimental treatment of human lymphoma over the last twenty years, providing evidence of biological efficacy, clinical efficacy and clinical benefit. However, the product that has come closer to regulatory approval is unlikely to clear that hurdle due to the insufficiently robust data obtained in a recently closed clinical trial. This review aims at discussing the reasons for hybridoma-derived idiotype vaccines, more difficult to produce but also more successful than recombinant idiotype vaccines so far, are unlikely to gain regulatory approval. In particular, it is necessary to examine the many peculiar features of this therapeutic approach in a broader context, with special attention to concepts like customized active immunotherapy and randomization. Most published trials based on hybridoma-derived idiotype vaccines are being analyzed, together with the yet non-peer reviewed data from the only randomized study conducted so far with this product, and with the main trials on recombinant idiotype vaccines for thorough comparison. All in all, the sole randomized trial ever conducted on hybridoma-derived idiotype vaccines failed to achieve its primary clinical end point because of an insufficient accrual and because the statistical significance achieved was not as stringent as required for regulatory approval. PMID- 27713272 TI - Dendritic Guanidines as Efficient Analogues of Cell Penetrating Peptides. AB - The widespread application of cell penetrating agents to clinical therapeutics and imaging agents relies on the ability to prepare them on a large scale and to readily conjugate them to their cargos. Dendritic analogues of cell penetrating peptides, with multiple guanidine groups on their peripheries offer advantages as their high symmetry allows them to be efficiently synthesized, while orthogonal functionalities at their focal points allow them to be conjugated to cargo using simple synthetic methods. Their chemical structures and properties are also highly tunable as their flexibility and the number of guanidine groups can be tuned by altering the dendritic backbone or the linkages to the guanidine groups. This review describes the development of cell-penetrating dendrimers based on several different backbones, their structure-property relationships, and comparisons of their efficacies with those of known cell penetrating peptides. The toxicities of these dendritic guanidines are also reported as well as their application towards the intracellular delivery of biologically significant cargos including proteins and nanoparticles. PMID- 27713274 TI - 2-Deoxystreptamine Conjugates by Truncation-Derivatization of Neomycin. AB - A small library of truncated neomycin-conjugates is prepared by consecutive removal of 2,6-diaminoglucose rings, oxidation-reductive amination of ribose, oxidation-conjugation of aminopyridine/aminoquinoline and finally dimerization. The dimeric conjugates were evaluated for antibacterial activity with a unique hemocyanin-based biosensor. Based on the outcome of these results, a second generation set of monomeric conjugates was prepared and found to display significant antibacterial activity, in particular with respect to kanamycin resistant E. coli. PMID- 27713278 TI - Liraglutide Therapy for Type 2 Diabetes: Overcoming Unmet Needs. AB - Although advances have been achieved in the management of type 2 diabetes, current treatment options for patients with this disease still fail to address disease progression, glycaemic control remains suboptimal and therapies are often associated with weight gain and hypoglycaemia. Thus, new antidiabetes therapies are being sought. Glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are incretin hormones that have been the recent focus of research. The physiological action of GLP-1, in particular, has demonstrated its potential in addressing the therapeutic needs of patients with type 2 diabetes. To exploit this action, liraglutide, a human GLP-1 analogue that shares 97% of its amino acid sequence identity with native GLP-1, has been developed. In a recent phase 3 trial programme (LEAD, Liraglutide Effect and Action in Diabetes), treatment with liraglutide was associated with substantial improvements in glycaemic control and low risk of hypoglycaemia. In addition, reductions in weight and systolic blood pressure were reported. There is also an indication that liraglutide is capable of improving beta-cell function and increasing beta-cell mass. Thus, liraglutide may overcome the limitations with current therapies and help to address the unmet clinical needs of patients with type 2 diabetes. PMID- 27713276 TI - Theophylline. AB - Theophylline (3-methyxanthine) has been used to treat airway diseases for over 70 years. It was originally used as a bronchodilator but the relatively high doses required are associated with frequent side effects, so its use declined as inhaled beta2-agonists became more widely used. More recently it has been shown to have anti-inflammatory effects in asthma and COPD at lower concentrations. The molecular mechanism of bronchodilatation is inhibition of phosphodiesterase(PDE)3 and PDE4, but the anti-inflammatory effect may be due to histone deacetylase (HDAC) activation, resulting in switching off of activated inflammatory genes. Through this mechanism theophylline also reverses corticosteroid resistance and this may be of particular value in severe asthma and COPD where HDAC2 activity is markedly reduced. Theophylline is given systemically (orally as slow-release preparations for chronic treatment and intravenously for acute exacerbations of asthma) and blood concentrations are determined mainly by hepatic metabolism, which may be increased or decreased in several diseases and by concomitant drug therapy. Theophylline is now usually used as an add-on therapy in asthma patients not well controlled on inhaled corticosteroids and in COPD patients with severe disease not controlled by bronchodilator therapy. Side effects are related to plasma concentrations and include nausea, vomiting and headaches due to PDE inhibition and at higher concentrations to cardiac arrhythmias and seizures due to adenosine A1-receptor antagonism. PMID- 27713279 TI - Implications of Inter-Individual Differences in Clopidogrel Metabolism, with Focus on Pharmacogenetics. AB - Increasing evidence for the role of pharmacogenetics in treatment resistance to the antiplatelet agent clopidogrel has been gained during the last years. Apart from CYP2C19 genetic polymorphisms, nongenetic factors, particularly drug-drug interactions, age and other clinical characteristics influence the interindividual variability in clopidogrel response to varying degrees. The present article reviews the so far accumulated evidence on the role of pharmacogenetic traits influencing CYP-activity as determinants of the antiplatelet response to clopidogrel, and its clinical implications. The genetic variation in CYP2C19 activity seems to influence short- and long-term antithrombotic effects of clopidogrel to a substantial extent. Prediction models for clopidogrel non-responsiveness that include CYP2C19 genotyping together with relevant non-genetic risk factors are needed to be verified for their potential benefit in individualization of antithrombotic therapy. PMID- 27713275 TI - Oxytocin and Major Depressive Disorder: Experimental and Clinical Evidence for Links to Aetiology and Possible Treatment. AB - Affective disorders represent the most common psychiatric diseases, with substantial co-morbidity existing between major depressive disorders (MDD) and anxiety disorders. The lack of truly novel acting compounds has led to non monoaminergic based research and hypotheses in recent years. The large number of brain neuropeptides, characterized by discrete synthesis sites and multiple receptors, represent likely research candidates for novel therapeutic targets. The present review summarises the available preclinical and human evidence regarding the neuropeptide, oxytocin, and its implications in the aetiology and treatment of MDD. While the evidence is not conclusive at present additional studies are warranted to determine whether OXT may be of therapeutic benefit in subsets of MDD patients such as those with comorbid anxiety symptoms and low levels of social attachment. PMID- 27713277 TI - Phytochemicals in the Control of Human Appetite and Body Weight. AB - Since obesity has grown to epidemic proportions, its effective management is a very important clinical issue. Despite the great amount of scientific effort that has been put into understanding the mechanisms that lead to overconsumption and overweight, at the moment very few approaches to weight management are effective in the long term. On the other hand, modern society is also affected by the growing incidence of eating disorders on the other side of the spectrum such as anorexia and bulimia nervosa which are equally difficult to treat. This review will try to summarise the main findings available in the literature regarding the effect of plants or plant extracts (phytochemicals) on human appetite and body weight. The majority of plant extracts are not single compounds but rather a mixture of different molecules, therefore their mechanism of action usually targets several systems. In addition, since some cellular receptors tend to be widely distributed, sometimes a single molecule can have a widespread effect. This review will attempt to describe the main phytochemicals that have been suggested to affect the homeostatic mechanisms that influence intake and body weight. Clinical data will be summarised and scientific evidence will be reviewed. PMID- 27713280 TI - Lambda Interferons: New Cytokines with Old Functions. AB - Interferon lambda (IFN-lambda) is a member of the class II cytokine family, and like the other members of this family, they are small helical proteins. Since their discovery significant efforts have been made to determine their role in innate and adaptive immunity. Their strong antiviral activity, both in vitro and in vivo, has firmly established their interferon status. However, in contrast to type I interferon, only a very limited subset of cells/tissues responds to interferon lambda. In addition to inducing an antiviral state in responsive cells, recent data suggest that IFN-l plays a role in shaping the adaptive immune response. However, the data is not in complete agreement regarding the effect of IFN-lambda on the adaptive immune system. Recently IFN-l has entered clinical trials against hepatitis C Virus and IFN-l is a promising future therapeutic, against different viruses replicating in responsive tissues, like that of the airway epithelia. In this review we describe the knowledge acquired during the past six years about the structure and function of interferon lambda. PMID- 27713281 TI - Synthetic Medicinal Chemistry in Chagas' Disease: Compounds at The Final Stage of "Hit-To-Lead" Phase. AB - Chagas' disease, or American trypanosomosiasis, has been the most relevant illness produced by protozoa in Latin America. Synthetic medicinal chemistry efforts have provided an extensive number of chemodiverse hits at the "active-to hit" stage. However, only a more limited number of these have been studied in vivo in models of Chagas' disease. Herein, we survey some of the cantidates able to surpass the "hit-to-lead" stage discussing their limitations or merit to enter in clinical trials in the short term. PMID- 27713282 TI - Combating Combination of Hypertension and Diabetes in Different Rat Models. AB - Rat experimental models are used extensively for studying physiological mechanisms and treatments of hypertension and diabetes co-existence. Each one of these conditions is a major risk factor for cardiovascular disease (CVD), and the combination of the two conditions is a potent enhancer of CVD. Five major animal models that advanced our understanding of the mechanisms and therapeutic approaches in humans are discussed in this review: Zucker, Goto-Kakizaki, SHROB, SHR/NDmcr-cp and Cohen Rosenthal diabetic hypertensive (CRDH) rats. The use of various drugs, such as angiotensin-converting enzyme (ACE) inhibitors (ACEIs), various angiotensin receptor blockers (ARBs), and calcium channel blockers (CCBs), to combat the effects of concomitant pathologies on the combination of diabetes and hypertension, as well as the non-pharmacological approach are reviewed in detail for each rat model. Results from experiments on these models indicate that classical factors contributing to the pathology of hypertension and diabetes combination-Including hypertension, hyperglycemia, hyperinsulinemia and hyperlipidemia-can now be treated, although these treatments do not completely prevent renal complications. Animal studies have focused on several mechanisms involved in hypertension/diabetes that remain to be translated into clinical medicine, including hypoxia, oxidative stress, and advanced glycation. Several target molecules have been identified that need to be incorporated into a treatment modality. The challenge continues to be the identification and interpretation of the clinical evidence from the animal models and their application to human treatment. PMID- 27713283 TI - The Renin-Angiotensin System in the Development of Salt-Sensitive Hypertension in Animal Models and Humans. AB - Hypertension is still one of the major causes of death from cardiovascular failure. Increased salt intake may aggravate the rise in blood pressure and the development of consequential damage of the heart, the vessels and other organs. The general necessity of restricted salt intake regardless of blood pressure or salt sensitivity has been a matter of debate over the past decades. This review summarizes the main pathogenic mechanisms of hypertension and salt sensitivity in rat models, particularly in the spontaneously hypertensive rat (SHR), and in patients with essential hypertension (EH). Although SHRs are commonly considered to be salt-resistant, there is much evidence that salt loading may deteriorate blood pressure and cardiovascular function even in these animals. Similarly, EH is not a homogenous disorder - some patients, but not all, exhibit pronounced salt sensitivity. The renin-angiotensin system (RAS) plays a key role in the regulation of blood pressure and salt and fluid homeostasis and thus is one of the main targets of antihypertensive therapy. This review focuses on the contribution of the RAS to the pathogenesis of salt-sensitive hypertension in SHRs and patients with EH. PMID- 27713286 TI - Cell-Penetrating Peptides: A Comparative Study on Lipid Affinity and Cargo Delivery Properties. AB - A growing number of natural and/or synthetic peptides with cell membrane penetrating capability have been identified and described in the past years. These molecules have been considered promising tools for delivering bioactive compounds into various cell types. Although the mechanism of uptake is still unclear, it is reasonable to assume that the relative contribute of each proposed mechanism could differ for the same peptide, depending on experimental protocol and cargo molecule composition. In this work we try to connect the capability to interact with model lipid membrane and structural and chemical characteristics of CPPs in order to obtain a biophysical classification that predicts the behavior of CPP-cargo molecules in cell systems. Indeed, the binding with cell membrane is one of the primary step in the interaction of CPPs with cells, and consequently the studies on model membrane could become important for understanding peptide membrane interaction on a molecular level, explaining how CPPs may translocate a membrane without destroying it and how this interactions come into play in shuttling CPPs via different routes with different efficiency. We analyzed by CD and fluorescence spectroscopies the binding properties of six different CPPs (kFGF, Nle54-Antp and Tat derived peptides, and oligoarginine peptides containing 6, 8 or 10 residues) in absence or presence of the same cargo peptide (the 392 401pTyr396 fragment of HS1 protein). The phospholipid binding properties were correlated to the conformational and chemical characteristics of peptides, as well as to the cell penetrating properties of the CPP-cargo conjugates. Results show that even if certain physico-chemical properties (conformation, positive charge) govern CPP capability to interact with the model membrane, these cannot fully explain cell-permeability properties. PMID- 27713287 TI - Synthesis and Neuroprotective Action of Optically Pure Neoechinulin A and Its Analogs. AB - We developed an efficient, stereoselective synthetic method for the diketopiperazine moiety of neoechinulin A and its derivatives. The intramolecular cyclization at 80 oC proceeded with minimal racemization of the stereogenic center at C-12 on neoechinulin A, even though the cyclization at 110 oC caused partial racemization. In contrast with these results, the cyclization on diketopiperazine of 8,9-dihydroneoechinulin A derivatives did not cause epimerization of the stereogenic centers, even at 110 degrees C. We examined the structure-activity relationships for the cytoprotective activity against cytotoxicity induced by 3-morpholinosydnonimine (SIN-1) in nerve growth factor (NGF)-differentiated PC12 cells. The C-8/C-9 double bond, but not the stereogenic center derived from alanine, was found to play a key role in the cytoprotective activity. PMID- 27713288 TI - Lessons Learned from Surveillance of Antimicrobial Susceptibilities of Pseudomonas aeruginosa at a Large Academic Medical Center. AB - This research report assessed the differences in resistance rates and antimicrobial usage-versus-susceptibility relationships of Pseudomonas aeruginosa found in various hospital patient care areas. A simplified case control study was also performed to identify patient-specific risk factors associated with cefepime resistant P. aeruginosa isolates. Last, we determined the consequence of combining mucoid and non-mucoid derived antimicrobial susceptibilities of P.aeruginosa into hospital antibiograms. Overall, susceptibility rates remained lower in the intensive care units (ICUs) compared to the non-ICU patient care areas, except for cefepime over the last time period. Cefepime utilization and antimicrobial-resistance rates among P. aeruginosa isolates had a significant relationship. Decreased meropenem exposure was associated with lower resistance rates relative to cefepime. Risk factors independently associated with cefepime resistant P. aeruginosa were structural lung disease, ICU admission, recent third generation cephalosporin use, frequent hospital admission and non-urine isolates. Large and statistically significant differences were observed between non-mucoid and combined percent susceptibility data for aminoglycosides. To control antimicrobial resistance and optimize initial empiric antimicrobial therapy, antimicrobial susceptibility and utilization patterns in specific patient care areas should be monitored and risk factors for antimicrobial resistance should be assessed. Mucoid strains of P. aeruginosa should not be included into antimicrobial susceptibility data as this may underestimate activity of most antipseudomonal agents. PMID- 27713290 TI - Imperatoxin A, a Cell-Penetrating Peptide from Scorpion Venom, as a Probe of Ca2+ Release Channels/Ryanodine Receptors. AB - Scorpion venoms are rich in ion channel-modifying peptides, which have proven to be invaluable probes of ion channel structure-function relationship. We previously isolated imperatoxin A (IpTxa), a 3.7 kDa peptide activator of Ca2+ release channels/ryanodine receptors (RyRs) [1,2,3] and founding member of the calcin family of scorpion peptides. IpTxa folds into a compact, mostly hydrophobic molecule with a cluster of positively-charged, basic residues polarized on one side of the molecule that possibly interacts with the phospholipids of cell membranes. To investigate whether IpTxa permeates external cellular membranes and targets RyRs in vivo, we perfused IpTxa on intact cardiomyocytes while recording field-stimulated intracellular Ca2+ transients. To further investigate the cell-penetrating capabilities of the toxin, we prepared thiolated, fluorescent derivatives of IpTxa. Biological activity and spectroscopic properties indicate that these derivatives retain high affinity for RyRs and are only 5- to 10-fold less active than native IpTxa. Our results demonstrate that IpTxa is capable of crossing cell membranes to alter the release of Ca2+in vivo, and has the capacity to carry a large, membrane-impermeable cargo across the plasma membrane, a finding with exciting implications for novel drug delivery. PMID- 27713285 TI - Beta-Adrenergic Agonists. AB - Inhaled beta2-adrenoceptor (beta2-AR) agonists are considered essential bronchodilator drugs in the treatment of bronchial asthma, both as symptoms relievers and, in combination with inhaled corticosteroids, as disease controllers. In this article, we first review the basic mechanisms by which the beta2-adrenergic system contributes to the control of airway smooth muscle tone. Then, we go on describing the structural characteristics of beta2-AR and the molecular basis of G-protein-coupled receptor signaling and mechanisms of its desensitization/ dysfunction. In particular, phosphorylation mediated by protein kinase A and beta-adrenergic receptor kinase are examined in detail. Finally, we discuss the pivotal role of inhaled beta2-AR agonists in the treatment of asthma and the concerns about their safety that have been recently raised. PMID- 27713284 TI - Cell-Penetrating Peptides-Mechanisms of Cellular Uptake and Generation of Delivery Systems. AB - The successful clinical application of nucleic acid-based therapeutic strategies has been limited by the poor delivery efficiency achieved by existing vectors. The development of alternative delivery systems for improved biological activity is, therefore, mandatory. Since the seminal observations two decades ago that the Tat protein, and derived peptides, can translocate across biological membranes, cell-penetrating peptides (CPPs) have been considered one of the most promising tools to improve non-invasive cellular delivery of therapeutic molecules. Despite extensive research on the use of CPPs for this purpose, the exact mechanisms underlying their cellular uptake and that of peptide conjugates remain controversial. Over the last years, our research group has been focused on the S413-PV cell-penetrating peptide, a prototype of this class of peptides that results from the combination of 13-amino-acid cell penetrating sequence derived from the Dermaseptin S4 peptide with the SV40 large T antigen nuclear localization signal. By performing an extensive biophysical and biochemical characterization of this peptide and its analogs, we have gained important insights into the mechanisms governing the interaction of CPPs with cells and their translocation across biological membranes. More recently, we have started to explore this peptide for the intracellular delivery of nucleic acids (plasmid DNA, siRNA and oligonucleotides). In this review we discuss the current knowledge of the mechanisms responsible for the cellular uptake of cell-penetrating peptides, including the S413-PV peptide, and the potential of peptide-based formulations to mediate nucleic acid delivery. PMID- 27713289 TI - Non Steroidal Anti-Inflammatory Drugs and Inflammatory Bowel Disease. AB - Inflammatory Bowel Diseases (IBD) are an immune mediated chronic or relapsing disorders of the gastrointestinal (GI) tract. IBD is characterized by a chronic intestinal inflammatory process with various components contributing to the pathogenesis of the disease including environmental factors such as smoking or use of Non Steroidal Anti-Inflammatory Drugs (NSAIDS). NSAIDS are among the most commonly used medications for the treatment of various inflammatory conditions. The main factor limiting NSAIDS use is the concern for the development of gastrointestinal toxicity including mucosal injury. A possible association between the use of NSAIDS and the onset or relapse of IBD has been repeatedly suggested. This article will review the current concepts and evidence of the relationship between IBD and NSAIDS. PMID- 27713291 TI - Ingested Type I Interferon-State of the Art as Treatment for Autoimmunity Part 2. AB - We have proposed a unifying hypothesis of the etiopathogenesis of autoimmunity that defines autoimmunity as a type I interferon (IFN) immunodeficiency syndrome. We have examined toxicity and potential efficacy in two phase I (type 1 diabetes [T1D], multiple sclerosis [MS]) and phase II clinical trials in T1D and MS. In a phase I open label trial in T1D, ingested IFN-alpha preserved residual beta-cell function in recent onset patients. In a second phase I trial in MS, there was a significant decrease in peripheral blood mononuclear cell IL-2 and IFN-gamma production after ingesting IFN-alpha. In a phase II randomized, placebo controlled, double-blind trial in MS, 10,000 IU ingested IFN-alpha significantly decreased gadolinium enhancements compared to the placebo group at month 5. TNF alpha and IFN-gamma cytokine secretion in the 10,000 IU group at month 5 showed a significant decrease that corresponded with the effect of ingested IFN-alpha on decreasing gadolinium enhancements. In a phase II randomized, placebo-controlled, double-blind trial in T1D, patients in the 5,000 unit hrIFN-alpha treatment group maintained more beta-cell function one year after study enrollment compared to individuals in the placebo group. Ingested IFN-alpha was not toxic in these clinical trials. These studies suggest that ingested IFN-alpha may have a potential role in the treatment of autoimmunity. PMID- 27713292 TI - The Impact of CYP2D6 Genotyping on Tamoxifen Treatment. AB - Tamoxifen remains a cornerstone of treatment for patients with oestrogen-receptor positive breast cancer. Tamoxifen efficacy depends on the biotransformation, predominantly via the cytochrome P450 2D6 (CYP2D6) isoform, to the active metabolite endoxifen. Both genetic and environmental (drug-induced) factors may alter CYP2D6 enzyme activity directly affecting the concentrations of active tamoxifen metabolites. Several studies suggest that germline genetic variants in CYP2D6 influence the clinical outcomes of patients treated with adjuvant tamoxifen. Here, we review the existing data relating CYP2D6 genotypes to tamoxifen efficacy. PMID- 27713293 TI - Lysostaphin: A Staphylococcal Bacteriolysin with Potential Clinical Applications. AB - Lysostaphin is an antimicrobial agent belonging to a major class of antimicrobial peptides and proteins known as the bacteriocins. Bacteriocins are bacterial antimicrobial peptides which generally exhibit bactericidal activity against other bacteria. Bacteriocin production is a self-protection mechanism that helps the microorganisms to survive in their natural habitats. Bacteriocins are currently distributed into three main classes. Staphylococcins are bacteriocins produced by staphylococci, which are Gram-positive bacteria of medical and veterinary importance. Lysostaphin is the only class III staphylococcin described so far. It exhibits a high degree of antistaphylococcal bacteriolytic activity, being inactive against bacteria of all other genera. Infections caused by staphylococci continue to be a problem worldwide not only in healthcare environments but also in the community, requiring effective measures for controlling their spread. Since lysostaphin kills human and animal staphylococcal pathogens, it has potential biotechnological applications in the treatment of staphylococcal infections. In vitro and in vivo studies performed with lysostaphin have shown that this staphylococcin has potential to be used, solely or in combination with other antibacterial agents, to prevent or treat bacterial staphylococcal infectious diseases. PMID- 27713295 TI - A Review of Anti-Inflammatory Drug-Induced Gastrointestinal Injury: Focus on Prevention of Small Intestinal Injury. AB - Capsule endoscopy and balloon endoscopy, advanced modalities that allow full investigation of the entire small intestine, have revealed that nonsteroidal anti inflammatory drugs (NSAIDs) can cause a variety of abnormalities in the small intestine. Recently, several reports show that traditional NSAIDs (tNSAIDs) and acetylsalicylic acid (ASA) can induce small intestinal injuries. These reports have shown that the preventive effect of proton pump inhibitors (PPIs) does not extend to the small intestine, suggesting that concomitant therapy may be required to prevent small intestinal side effects associated with tNSAID/ASA use. Recently, several randomized controlled trials used capsule endoscopy to evaluate the preventive effect of mucoprotective drugs against tNSAID/ASA-induced small intestinal injury. These studies show that misoprostol and rebamipide reduce the number and types of tNSAID-induced small intestinal mucosal injuries. However, those studies were limited to a small number of subjects and tested short-term tNSAID/ ASA treatment. Therefore, further extensive studies are clearly required to ascertain the beneficial effect of these drugs. PMID- 27713294 TI - Safety, Tolerability, and Immunogenicity of Interferons. AB - Interferons (IFNs) are class II cytokines that are key components of the innate immune response to virus infection. Three IFN sub-families, type I, II, and III IFNs have been identified in man, Recombinant analogues of type I IFNs, in particular IFNalpha2 and IFNbeta1, have found wide application for the treatment of chronic viral hepatitis and remitting relapsing multiple sclerosis respectively. Type II IFN, or IFN gamma, is used principally for the treatment of chronic granulomatous disease, while the recently discovered type III IFNs, also known as IFN lambda or IL-28/29, are currently being evaluated for the treatment of chronic viral hepatitis. IFNs are in general well tolerated and the most common adverse events observed with IFNalpha or IFNbeta therapy are "flu-like" symptoms such as fever, headache, chills, and myalgia. Prolonged treatment is associated with more serious adverse events including leucopenia, thrombocytopenia, increased hepatic transaminases, and neuropsychiatric effects. Type I IFNs bind to high-affinity cell surface receptors, composed of two transmembrane polypeptides IFNAR1 and IFNAR2, resulting in activation of the Janus kinases Jak1 and Tyk2, phosphorylation and activation of the latent cytoplasmic signal transducers and activators of transcription (STAT1) and STAT2, formation of a transcription complex together with IRF9, and activation of a specific set of genes that encode the effector molecules responsible for mediating the biological activities of type I IFNs. Systemic administration of type I IFN results in activation of IFN receptors present on essentially all types of nucleated cells, including neurons and hematopoietic stem cells, in addition to target cells. This may well explain the wide spectrum of IFN associated toxicities. Recent reports suggest that certain polymorphisms in type I IFN signaling molecules are associated with IFN-induced neutropenia and thrombocytopenia in patients with chronic hepatitis C. IFNgamma binds to a cell surface receptor composed of two transmembrane polypeptides IFGR1 and IFGR2 resulting in activation of the Janus kinases Jak1 and Jak2, phosphorylation of STAT1, formation of STAT1 homodimers, and activation of a specific set of genes that encode the effector molecules responsible for mediating its biological activity. In common with type I IFNs, IFNgamma receptors are ubiquitous and a number of the genes activated by IFNgamma are also activated by type I IFNs that may well account for a spectrum of toxicities similar to that associated with type I IFNs including "flu-like" symptoms, neutropenia, thrombocytopenia, and increased hepatic transaminases. Although type III IFNs share the major components of the signal transduction pathway and activate a similar set of IFN stimulated genes (ISGs) as type I IFNs, distribution of the IFNlambda receptor is restricted to certain cell types suggesting that IFNlambda therapy may be associated with a reduced spectrum of toxicities relative to type I or type II IFNs. Repeated administration of recombinant IFNs can cause in a break in immune tolerance to self-antigens in some patients resulting in the production of neutralizing antibodies (NABs) to the recombinant protein homologue. Appearance of NABs is associated with reduced pharmacokinetics, pharmacodynamics, and a reduced clinical response. The lack of cross-neutralization of IFNbeta by anti IFNalpha NABs and vice versa, undoubtedly accounts for the apparent lack of toxicity associated with the presence of anti-IFN NABs with the exception of relatively mild infusion/injection reactions. PMID- 27713297 TI - Tyrosine Kinase Inhibitors as Antiangiogenic Drugs in Multiple Myeloma. AB - Tyrosine kinase inhibitors are a new class of anticancer drugs, that are capable of directly interacting with the catalytic site of the target enzyme and thereby inhibiting catalysis. Therapeutically useful tyrosine kinase inhibitors are not specific for a single tyrosine kinase, but rather they are selective against a limited number of tyrosine kinases. The success of imatinib-mesylate (Gleevec(r)) for the treatment of patients with chronic myeloid leukemia has opened a intensive search for new small molecular compounds able to target other protein tyrosine kinases involved in the malignant transformation. This review article is focused on the use of tyrosine kinase inhibitors as antiangiogenic molecules in the treatment of multiple myeloma. PMID- 27713296 TI - New Trends in Cancer Therapy: Targeting Ion Channels and Transporters. AB - The expression and activity of different channel types mark and regulate specific stages of cancer establishment and progression. Blocking channel activity impairs the growth of some tumors, both in vitro and in vivo, which opens a new field for pharmaceutical research. However, ion channel blockers may produce serious side effects, such as cardiac arrhythmias. For instance, Kv11.1 (hERG1) channels are aberrantly expressed in several human cancers, in which they control different aspects of the neoplastic cell behaviour. hERG1 blockers tend to inhibit cancer growth. However they also retard the cardiac repolarization, thus lengthening the electrocardiographic QT interval, which can lead to life-threatening ventricular arrhythmias. Several possibilities exist to produce less harmful compounds, such as developing specific drugs that bind hERG1 channels in the open state or disassemble the ion channel/integrin complex which appears to be crucial in certain stages of neoplastic progression. The potential approaches to improve the efficacy and safety of ion channel targeting in oncology include: (1) targeting specific conformational channel states; (2) finding ever more specific inhibitors, including peptide toxins, for channel subtypes mainly expressed in well-identified tumors; (3) using specific ligands to convey traceable or cytotoxic compounds; (4) developing channel blocking antibodies; (5) designing new molecular tools to decrease channel expression in selected cancer types. Similar concepts apply to ion transporters such as the Na+/K+ pump and the Na+/H+ exchanger. Pharmacological targeting of these transporters is also currently being considered in anti-neoplastic therapy. PMID- 27713298 TI - Cell-Penetrating Fragments of the Cdk5 Regulatory Subunit Are Protective in Models of Neurodegeneration. AB - Cdk5 is essential for neuronal differentiation processes in the brain. Activation of Cdk5 requires the association with the mostly neuron-specific p35 or p39. Overactivation of CDK5 by cleavage of p35 into p25 is thought to be involved in neurodegenerative processes. Here, we have tested an approach to inhibit pathological Cdk5 activation with a Tat-linked dominant-negative fragment of p25. It reduced cell death induced by staurosporine and showed a tendency to alleviate manganese-induced cell death, while it did not protect against 6-OHDA toxicity. Our results suggest that the Tat technique is a suitable tool to inhibit dysregulated CDK5. PMID- 27713300 TI - Significant Acute Kidney Injury Due to Non-steroidal Anti-inflammatory Drugs: Inpatient Setting. AB - In the United States non-steroidal anti-inflammatory drugs (NSAID) are freely available over-the-counter. Because of the adverse effects on the kidneys and the popularity of these drugs, unregulated use of NSAIDs is an under recognized and potentially dangerous problem. Fifteen inpatients, mean age of 15.2 +/- 2.3 years (five males, 10 females), were referred to nephrology for acute kidney injury. All patients admitted to taking ibuprofen and six also consumed naproxen. None of the patients had underlying renal diseases at the time of admission. Nine patients had proteinuria and 12 had hematuria (including one with gross hematuria). One patient had nephrotic syndrome but the condition resolved spontaneously without steroids and has remained in remission for four years. Two patients required dialysis. Only one of the dialyzed patients required steroid therapy for recovery of renal function. The mean duration of hospitalization was 7.4 +/- 5.5 days. The serum creatinine peaked at 4.09 +/- 4.24 (range 1.2-15.3) mg/dL. All patients recovered renal function with normalization of serum creatinine to 0.71 +/- 0.15 mg/dL. The estimated GFR (glomerular filtration rate) at peak of renal failure was 38.2 +/- 20.5 mL/min but did improve to a baseline of 134 +/- 26.2 mL/min (range 89-177, p < 0.01). However, the duration from onset to normalization of serum creatinine was 37 +/- 42 days indicating that majority of patients had abnormal renal function for a prolonged period. In conclusion, NSAIDs pose a significant risk of renal failure for significant duration and as an entity may be under recognized. PMID- 27713302 TI - The Treatment of Melioidosis. AB - Melioidosis is a complex bacterial infection, treatment of which combines the urgency of treating rapidly fatal Gram negative septicaemia with the need for eradication of long-term persistent disease in pulmonary, soft tissue, skeletal and other organ systems. Incremental improvements in treatment have been made as a result of multicentre collaboration across the main endemic region of Southeast Asia and northern Australia. There is an emerging consensus on the three main patterns of antimicrobial chemotherapy; initial (Phase 1) treatment, subsequent eradication (Phase 2) therapy and most recently post-exposure (Phase 0) prophylaxis. The combination of agents used, duration of therapy and need for adjunct modalities depends on the type, severity and antimicrobial susceptibility of infection. New antibiotic and adjunct therapies are at an investigational stage but on currently available data are unlikely to make a significant impact on this potentially fatal infection. PMID- 27713301 TI - Effects of NSAIDs on the Inner Ear: Possible Involvement in Cochlear Protection. AB - Cyclooxygenase and lipoxygenase, two important enzymes involved in arachidonic acid metabolism, are major targets of non-steroidal anti-inflammatory drugs (NSAIDs). Recent investigations suggest that arachidonic cascades and their metabolites may be involved in maintaining inner ear functions. The excessive use of aspirin may cause tinnitus in humans and impairment of the outer hair cell functions in experimental animals. On the other hand, NSAIDs reportedly exhibit protective effects against various kinds of inner ear disorder. The present review summarizes the effects of NSAIDs on cochlear pathophysiology. NSAIDs are a useful ameliorative adjunct in the management of inner ear disorders. PMID- 27713303 TI - The Role of Non-Steroidal Anti-Inflammatory Drugs in Renal Colic. AB - NSAIDs provide optimal analgesia in renal colic due to the reduction in glomerular filtration and renal pelvic pressure, ureteric peristalsis and ureteric oedema. Prevention of glomerular afferent arteriolar vasodilatation renders these patients at risk of renal impairment. NSAIDs have the additional benefit of reducing the number of new colic episodes and preventing subsequent readmission to hospital. Despite recent work promoting the use of pharmacological agents to improve stone passage rates, NSAIDs do not appear to reduce the time to stone passage or increase the likelihood of stone passage in renal colic. PMID- 27713299 TI - Thrombospondin-1 as a Paradigm for the Development of Antiangiogenic Agents Endowed with Multiple Mechanisms of Action. AB - Uncontrolled neovascularization occurs in several angiogenesis-dependent diseases, including cancer. Neovascularization is tightly controlled by the balance between angiogenic growth factors and antiangiogenic agents. The various natural angiogenesis inhibitors identified so far affect neovascularization by different mechanisms of action. Thrombospondin-1 (TSP-1) is a matricellular modular glycoprotein that acts as a powerful endogenous inhibitor of angiogenesis. It acts both indirectly, by sequestering angiogenic growth factors and effectors in the extracellular environment, and directly, by inducing an antiangiogenic program in endothelial cells following engagement of specific receptors including CD36, CD47, integrins and proteoglycans (all involved in angiogenesis ). In view of its central, multifaceted role in angiogenesis, TSP-1 has served as a source of antiangiogenic tools, including TSP-1 fragments, synthetic peptides and peptidomimetics, gene therapy strategies, and agents that up-regulate TSP-1 expression. This review discusses TSP-1-based inhibitors of angiogenesis, their mechanisms of action and therapeutic potential, drawing our experience with angiogenic growth factor-interacting TSP-1 peptides, and the possibility of exploiting them to design novel antiangiogenic agents. PMID- 27713304 TI - Prospects for the Use of ATR Inhibitors to Treat Cancer. AB - ATR is an apical kinase in one of the DNA-damage induced checkpoint pathways. Despite the development of inhibitors of kinases structurally related to ATR, as well as inhibitors of the ATR substrate Chk1, no ATR inhibitors have yet been developed. Here we review the effects of ATR downregulation in cancer cells and discuss the potential for development of ATR inhibitors for clinical use. PMID- 27713306 TI - Health Economics of Antibiotics. AB - Antibiotics have made a significant contribution to improving patient health, but policy makers and health care payers are concerned about the costs of antibiotics in addition to their effectiveness. This paper aims to assess the value of antibiotics by examining incremental cost-utility ratios of antibiotics. Evidence was derived from cost-utility analyses of antibiotics included in the Tufts-New England Center Cost-Effectiveness Analysis Registry through September 2009. The analysis included 85 incremental cost-utility ratios from 23 cost-utility analyses. The findings showed that 38.8% of incremental cost-utility ratios related to dominant antibiotics (i.e., more effective and less costly than the comparator); 45.9% referred to antibiotics that improved effectiveness, but also increased costs; and 15.3% related to dominated antibiotics (i.e., less effective and more costly than the comparator). The median ratio was 748 ? per quality adjusted life year. Using threshold values of 20,000 ? per quality-adjusted life year and 50,000 ? per quality-adjusted life year, the probability that an antibiotic provides value for money was 64% and 67%, respectively. The current evidence base suggests that the majority of antibiotics provide value for money and that antibiotics can aid decision makers to attain further population health improvements, whilst containing pharmaceutical expenditures. PMID- 27713305 TI - NSAIDs, Opioids, Cannabinoids and the Control of Pain by the Central Nervous System. AB - Nonsteroidal anti-inflammatory drugs (NSAIDs) act upon peripheral tissues and upon the central nervous system to produce analgesia. A major central target of NSAIDs is the descending pain control system. The rostral structures of the descending pain control system send impulses towards the spinal cord and regulate the transmission of pain messages. Key structures of the descending pain control system are the periaqueductal gray matter (PAG) and the rostral ventromedial region of the medulla (RVM), both of which are critical targets for endogenous opioids and opiate pharmaceuticals. NSAIDs also act upon PAG and RVM to produce analgesia and, if repeatedly administered, induce tolerance to themselves and cross-tolerance to opioids. Experimental evidence shows that this is due to an interaction of NSAIDs with endogenous opioids along the descending pain control system. Analgesia by NSAIDs along the descending pain control system also requires an activation of the CB1 endocannabinoid receptor. Several experimental approaches suggest that opioids, NSAIDs and cannabinoids in PAG and RVM cooperate to decrease GABAergic inhibition and thus enhance the descending flow of impulses that inhibit pain. PMID- 27713307 TI - Lp-PLA2 Inhibition-The Atherosclerosis Panacea? AB - Based on the complex pathophysiology of atherosclerosis, a large number of biomarkers that relate to lipids, inflammation, immunity, thrombosis and hemostasis, have been investigated experimentally, in epidemiologic studies and in clinical trials. Interest focuses on their potential role to aid in risk stratification, as possible surrogate markers of atherosclerosis, and potential targets for therapy. More recently, one lipid associated biomarker, lipoprotein associated phospholipase A2 (Lp-PLA2), has gained considerable interest. In addition to a plausible pathophysiological role by generating pro-inflammatory and pro-atherogenic compounds from oxidized LDL in the vessel wall, there is a large, fairly consistent epidemiological database indicating that increased levels of Lp-PLA2 mass or activity are associated with increased risk for cardiovascular outcomes; such data further suggest that it might improve risk stratification. In addition, clinical studies indicate that increased Lp-PLA2 levels are associated with endothelial dysfunction. Moreover, it may also serve as an interesting therapeutic target, since a specific inhibitor of the enzyme is available with promising animal data and initial positive data in humans. Recent experimental data from a hyperlipidemic diabetic pig model strongly suggest that increased Lp-PLA2 in the vessel wall is associated with a more vulnerable plaque phenotype which can be modulated by inhibiting Lp-PLA2 activity. A biomarker study in more than 1,000 patients with CHD over three months has demonstrated a positive effect on various inflammatory molecules. In addition, an imaging study using IVUS based modalities (greyscale, virtual histology, and palpography) together with a panel of biomarkers (IBIS-2) has been done in more than 300 patients with CHD treated over 12 months and results indicate that the progression of the necrotic core of the plaque can be retarded. Inhibition of the pro-atherogenic and pro-inflammatory effects of Lp-PLA2 may therefore contribute to decrease the residual risk in high risk patients already on polypharmacotherapy. This hypothesis is now being tested in two large phase 3 clinical trials. Thus, Lp-PLA2 indeed may represent a biomarker and a promising target for intervention. PMID- 27713308 TI - Combining Biofilm-Controlling Compounds and Antibiotics as a Promising New Way to Control Biofilm Infections. AB - Many bacteria grow on surfaces forming biofilms. In this structure, they are well protected and often high dosages of antibiotics cannot clear infectious biofilms. The formation and stabilization of biofilms are mediated by diffusible autoinducers (e.g. N-acyl homoserine lactones, small peptides, furanosyl borate diester). Metabolites interfering with this process have been identified in plants, animals and microbes, and synthetic analogues are known. Additionally, this seems to be not the only way to control biofilms. Enzymes capable of cleaving essential components of the biofilm matrix, e.g. polysaccharides or extracellular DNA, and thus weakening the biofilm architecture have been identified. Bacteria also have mechanisms to dissolve their biofilms and return to planktonic lifestyle. Only a few compounds responsible for the signalling of these processes are known, but they may open a completely novel line of biofilm control. All these approaches lead to the destruction of the biofilm but not the killing of the pathogens. Therefore, a combination of biofilm-destroying compounds and antibiotics to handle biofilm infections is proposed. In this article, different approaches to combine biofilm-controlling compounds and antibiotics to fight biofilm infections are discussed, as well as the balance between biofilm formation and virulence. PMID- 27713309 TI - Effects of NSAIDs on Differentiation and Function of Human and Murine Osteoclasts - Crucial 'Human Osteoclastology'. AB - Osteoclasts play a critical role in both normal bone metabolism and bone resorption in the joints of patients with rheumatoid arthritis. It has been reported that non-steroidal anti-inflammatory drugs (NSAIDs) inhibit murine osteoclastogenesis in vitro and murine arthritis models in vivo, but not the destruction of joints of patients with rheumatoid arthritis. In the current review article, we review the recent findings in the effect of NSAIDs on the formation and function of human and murine osteoclasts both in vitro and in vivo, underlining the importance of studies using human osteoclasts. Since 2009, we have suggested a novel term 'human osteoclastology'. PMID- 27713311 TI - Natural Products in Epilepsy-the Present Situation and Perspectives for the Future. AB - More efficacious and better tolerated treatments for epilepsy are clearly needed. Complementary and alternative medicine (CAM) has a long history of use in certain parts of the world and has gained increasing interest over the last decades in Western countries. In countries with a Western-based type of medical system, people with epilepsy (PWE) take natural products or engage in other forms of CAM mainly to enhance general health, but also to prevent seizures or to alleviate symptoms of comorbidities or side effects of antiepileptic medications. In other countries, well developed medical systems, such as traditional Chinese Medicine and Ayurveda, are often the basis for treating PWE. Based on anecdotal reports of efficacy in PWE, natural products from these and other traditions are increasingly being studied in animal models of epilepsy, and candidates for further clinical development have been identified. It is likely, therefore, that natural products will be further evaluated for safety, tolerability and efficacy in PWE with drug-resistant seizures. PMID- 27713310 TI - Acid-Sensing Ion Channels and Pain. AB - Pathophysiological conditions such as inflammation, ischemia, infection and tissue injury can all evoke pain, and each is accompanied by local acidosis. Acid sensing ion channels (ASICs) are proton-gated cation channels expressed in both central and peripheral nervous systems. Increasing evidence suggests that ASICs represent essential sensors for tissue acidosis-related pain. This review provides an update on the role of ASICs in pain sensation and discusses their therapeutic potential for pain management. PMID- 27713312 TI - Suppression of Autoimmune Arthritis by Small Molecule Inhibitors of the JAK/STAT Pathway. AB - A skewed ratio of pro-inflammatory to anti-inflammatory cytokines, elevated growth factor synthesis and T- and B-lymphocyte activation are 3 hallmarks of rheumatoid arthritis (RA) pathology. Interleukin-6 (IL-6), IL-7, IL-17, IL-12/IL 23 and growth factors, granulocyte macrophage-colony stimulating factor, IL-3, and erythropoietin activate the Janus Kinase/Signal Transducers and Activators of Transcription (JAK/STAT) pathway. Evidence showed that STAT protein phosphorylation (p-STAT) by activated JAKs is permissive for p-STAT to act as transcription factors by binding to STAT-responsive gene promoter sequences. This event is critical for perpetuating RA, in part, by up-regulating pro-inflammatory cytokine gene transcription. Activation of JAK/STAT by cytokines and growth factors can induce 'cross-talk' with other signaling pathways by which Stress Activated Protein/Mitogen-Activated Protein Kinase (SAP/MAPK) and Phosphatidylinositide-3-Kinase (PI3K)-mediated signaling are also activated. JAK specific small molecule inhibitors (SMIs) were developed to test whether JAK/STAT pathway blockade would regulate autoimmune-mediated inflammation. JAK-specific SMI blockade inhibited p-STAT induced by pro-inflammatory cytokines in vitro. Systemically administered JAK-specific SMI blockade also ameliorated biomarkers of inflammation in well-validated arthritis animal models. A few JAK-specific SMIs have made their way into RA clinical trials. In fact, the JAK3-specific SMI, CP-690,500 is the first JAK/STAT SMI to be assessed for clinical efficacy in a Phase III RA trial. PMID- 27713314 TI - Critical Overview on the Benefits and Harms of Aspirin. AB - Aspirin is widely used internationally for a variety of indications, with the most prominent one being that of cardiovascular disease. However, aspirin has also been proposed as a treatment option in a diverse range of conditions such as diabetes mellitus, cancer prevention, and obstetrics. In our overview, we critically appraise the current evidence from recent systematic reviews and meta analyses covering the benefits of aspirin across these conditions. We also look at evidence that some patients may not derive benefit due to the concept of aspirin resistance. Aspirin is also associated with the potential for significant harm, principally from haemorrhagic adverse events. We critically appraise the threat of haemorrhagic complications, and weigh up these risks against that of any potential benefit. PMID- 27713313 TI - Building Cell Selectivity into CPP-Mediated Strategies. AB - There is a pressing need for more effective and selective therapies for cancer and other diseases. Consequently, much effort is being devoted to the development of alternative experimental approaches based on selective systems, which are designed to be specifically directed against target cells. In addition, a large number of highly potent therapeutic molecules are being discovered. However, they do not reach clinical trials because of their low delivery, poor specificity or their incapacity to bypass the plasma membrane. Cell-penetrating peptides (CPPs) are an open door for cell-impermeable compounds to reach intracellular targets. Putting all these together, research is sailing in the direction of the design of systems with the capacity to transport new drugs into a target cell. Some CPPs show cell type specificity while others require modifications or form part of more sophisticated drug delivery systems. In this review article we summarize several strategies for directed drug delivery involving CPPs that have been reported in the literature. PMID- 27713315 TI - Targeted Therapy of Cancer Using Photodynamic Therapy in Combination with Multi faceted Anti-Tumor Modalities. AB - Photodynamic therapy (PDT) has emerged as one of the important therapeutic options in the management of cancer and other diseases. PDT involves a tumor localized photosensitizer (PS), which when appropriately illuminated by visible light converts oxygen into cytotoxic reactive oxygen species (ROS), that attack key structural entities within the targeted cells, ultimately resulting in necrosis or apoptosis. Though PDT is a selective modality, it can be further enhanced by combining other targeted therapeutic strategies that include the use of synthetic peptides and nanoparticles for selective delivery of photosensitizers. Another potentially promising strategy is the application of targeted therapeutics that exploit a myriad of critical pathways involved in tumorigenesis and metastasis. Vascular disrupting agents that eradicate tumor vasculature during PDT and anti-angiogenic agents that targets specific molecular pathways and prevent the formation of new blood vessels are novel therapeutic approaches that have been shown to improve treatment outcome. In addition to the well-documented mechanisms of direct cell killing and damage to the tumor vasculature, PDT can also activate the body's immune response against tumors. Numerous pre-clinical studies and clinical observations have demonstrated the immuno-stimulatory capability of PDT. Herein, we aim to integrate the most important findings with regard to the combination of PDT and other novel targeted therapy approaches, detailing its potential in cancer photomedicine. PMID- 27713317 TI - The Role of Non-Steroidal Anti-Inflammatory Drugs in the Chemoprevention of Breast Cancer. AB - Epidemiological evidence suggests that non-steroidal anti-inflammatory drugs (NSAIDs) which act as cyclooxygenase (COX-2) inhibitors may reduce breast cancer incidence by up to 20%. These agents are often taken for pain relief by older women with osteoarthritis. Age is the major risk factor for breast cancer in women with 50% cases being diagnosed in those aged >65 years. NSAIDs reduce serum estradiol by 17% in post-menopausal women and since most of these who develop breast cancers have estrogen receptor positive tumours; this suggests a possible preventative role. Careful use of these agents could provide a strategy for both relief of symptoms of osteoarthritis and also breast cancer prevention. Instead of conducting a randomised trial, proof of efficacy could be from an adequately powered cohort study within the breast screening programme. PMID- 27713316 TI - Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Progress in Small Molecule Drug Development. AB - Ever since the discovery of aspirin, small molecule therapeutics have been widely prescribed to treat inflammation and pain. Aspirin and several small molecule NSAIDs are known to inhibit the enzymes cyclooxygenase-1 (COX-1) and -2 (COX-2). Despite the success of NSAIDs to treat inflammatory disorders, the development of a clinically useful small molecule NSAIDs with decreased side effect profiles is an ongoing effort. The recent discovery and development of selective COX-2 inhibitors was a step toward this direction. Emerging trends are represented by the progress in the development of hybrid agents such as nitric oxide donor NSAIDs (NO-NSAIDs) and dual COX/lipoxygenase (LOX) inhibitors. This review focuses on the recent advances in the rational design of small molecule NSAIDs in therapy. PMID- 27713318 TI - Chemoprophylaxis of Tropical Infectious Diseases. AB - Travelers to tropical countries are at risk for a variety of infectious diseases. In some cases effective vaccinations are available, but for other infections chemoprophylaxis can be offered. Malaria prevention has become increasingly complex as Plasmodium species become resistant to available drugs. In certain high risk settings, antibiotics can be used to prevent leptospirosis, scrub typhus and other infections. Post-exposure prophylaxis is appropriate for selected virulent infections. In this article the evidence for chemoprophylaxis will be reviewed. PMID- 27713321 TI - Beyond Genetics-Stratified and Personalised Medicines Using Multiple Parameters. AB - Prescribers have been practicing stratified medicine for many years. Patient characteristics, usually non-genetic, including age, comorbidities and concomitant medications are taken into account when deciding which drug to prescribe. In addition, the majority of drugs require dose adjustments across patient subgroups, usually determined by non-genetic differences between the subgroups. Whilst pharmacogenetics hold promise for enhancing treatment stratification and even treatment individualisation, non-genetic factors will continue to be very important. Both non-genetic and genetic factors must be considered to improve understanding and quantification of the variability in treatment outcomes and to guide stratification and targeting of patient subgroups to the right drug and also to the right range of doses within that subgroup. Development of stratified medicines must consider non-genetic as well as genetic factors and, where appropriate, include stratification through optimising the dose for each patient or subgroup as well as by choosing the drug most likely to deliver efficacy to that patient or group. PMID- 27713319 TI - NSAIDs, Mitochondria and Calcium Signaling: Special Focus on Aspirin/Salicylates. AB - Aspirin (acetylsalicylic acid) is a well-known nonsteroidal anti-inflammatory drug (NSAID) that has long been used as an anti-pyretic and analgesic drug. Recently, much attention has been paid to the chemopreventive and apoptosis inducing effects of NSAIDs in cancer cells. These effects have been thought to be primarily attributed to the inhibition of cyclooxygenase activity and prostaglandin synthesis. However, recent studies have demonstrated unequivocally that certain NSAIDs, including aspirin and its metabolite salicylic acid, exert their anti-inflammatory and chemopreventive effects independently of cyclooxygenase activity and prostaglandin synthesis inhibition. It is becoming increasingly evident that two potential common targets of NSAIDs are mitochondria and the Ca2+ signaling pathway. In this review, we provide an overview of the current knowledge regarding the roles of mitochondria and Ca2+ in the apoptosis inducing effects as well as some side effects of aspirin, salicylates and other NSAIDs, and introducing the emerging role of L-type Ca2+ channels, a new Ca2+ entry pathway in non-excitable cells that is up-regulated in human cancer cells. PMID- 27713320 TI - Molecular Mechanism for Various Pharmacological Activities of NSAIDS. AB - The anti-inflammatory action of non-steroidal anti-inflammatory drugs (NSAIDs) is mediated through their inhibitory effects on cyclooxygenase (COX) activity. On the other hand, NSAID use is often associated with gastrointestinal complications. The inhibition of COX by NSAIDs is not the sole explanation for the gastrointestinal side effects of NSAIDs. Furthermore, recent epidemiological studies have revealed that prolonged NSAID use reduces the risk of cancer and Alzheimer's disease (AD) and a COX-independent unknown mechanism is suggested to be involved in these activities of NSAIDs. In this article, I review our recent work on the COX-independent mechanism involved in NSAID-induced gastric lesions and anti-tumor and anti-AD activities of NSAIDs. Using DNA microarray analysis, we found that NSAIDs affect expression of various genes in a COX-independent manner. We found that membrane permeabilization activity of NSAIDs and resulting NSAID-induced apoptosis are involved in NSAID-induced gastric lesions. On the other hand, induction of expression of tight junction-related genes and endoplasmic reticulum chaperones were suggested to be involved in anti-tumor and anti-AD, respectively, activities of NSAIDs. These results suggest that NSAIDs affect expression of various genes in a COX-independent manner, which is involved in various pharmacological activities of NSAIDs. PMID- 27713322 TI - NSAIDs: Old Drugs Reveal New Anticancer Targets. AB - There is compelling evidence that nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase-2 selective inhibitors have antineoplastic activity, but toxicity from cyclooxygenase (COX) inhibition and the suppression of physiologically important prostaglandins limits their use for cancer chemoprevention. Previous studies as reviewed here suggest that the mechanism for their anticancer properties does not require COX inhibition, but instead involves an off-target effect. In support of this possibility, recent molecular modeling studies have shown that the NSAID sulindac can be chemically modified to selectively design out its COX-1 and COX-2 inhibitory activity. Unexpectedly, certain derivatives that were synthesized based on in silico modeling displayed increased potency to inhibit tumor cell growth. Other experiments have shown that sulindac can inhibit phosphodiesterase to increase intracellular cyclic GMP levels and that this activity is closely associated with its ability to selectively induce apoptosis of tumor cells. Together, these studies suggest that COX-independent mechanisms can be targeted to develop safer and more efficacious drugs for cancer chemoprevention.

We review here the antimicrobial properties of cobalt coordination complexes in oxidation state 3+. In addition to reviewing the cobalt complexes containing polydentate donor ligands, we also focus on the antimicrobial activity of the homoleptic [Co(NH3)6]3+ ion. PMID- 27713326 TI - The Role of Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) in the Management of the Post-Embolization Symptoms after Uterine Artery Embolization. AB - Uterine artery embolization (UAE) is usually a very painful procedure. Although pain after the procedure can occur as a single symptom, it usually is associated with other symptoms such as nausea, vomiting, pelvic pain, general malaise, fever and leukocytosis that characterize the post-embolization syndrome. Management of the post-embolization symptoms and of pain in particular, is paramount if UAE is to be performed as an outpatient procedure. Different protocols have used analgesic and/or anti-inflammatory agents to control these symptoms. Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used in association with analgesic drugs to control post-embolization symptoms. In our institution the patients start oral medication with NSAIDs the day before the procedure and continue it during and after UAE. We also mix NSAIDs with the embolizing particles. This enables a reduction in the inflammation present in the uterine fibroids and helps controlling the pain. The purpose of this paper is to review the importance of NSAIDs in the management of the post-embolization symptoms. We describe the protocol that we use in our institution that enables us to perform the procedure on an outpatient basis with same day discharge and good control of the post-embolization symptoms with oral NSAIDs and analgesics. PMID- 27713323 TI - Effect of Non-Steroidal Anti-Inflammatory Drugs on Bone Healing. AB - Nonspecific and COX-2 selective nonsteroidal anti-inflammatory drugs (NSAIDs) function by inhibiting the cyclooxygenase isoenzymes and effectively reduce pain and inflammation attributed to acute or chronic musculoskeletal pathologies. However, use of NSAIDs as an analgesic is thought to negatively contribute to bone healing. This review strived to provide a thorough unbiased analysis of the current research conducted on animals and humans regarding NSAIDs and their effect on bone healing. Specifically, this review discusses the role of animal models, dosing regiments, and outcome parameters when examining discrepancies about NSAIDS and their effects on bone regeneration. The role of COX-2 in bone regeneration needs to be better defined in order to further elucidate the impact of NSAIDs on bone healing. PMID- 27713324 TI - Beneficial and Harmful Interactions of Antibiotics with Microbial Pathogens and the Host Innate Immune System. AB - In general antibiotics interact cooperatively with host defences, weakening and decreasing the virulence of microbial pathogens, thereby increasing vulnerability to phagocytosis and eradication by the intrinsic antimicrobial systems of the host. Antibiotics, however, also interact with host defences by several other mechanisms, some harmful, others beneficial. Harmful activities include exacerbation of potentially damaging inflammatory responses, a property of cell wall targeted agents, which promotes the release of pro-inflammatory microbial cytotoxins and cell-wall components. On the other hand, inhibitors of bacterial protein synthesis, especially macrolides, possess beneficial anti inflammatory/cytoprotective activities, which result from interference with the production of microbial virulence factors/cytotoxins. In addition to these pathogen-directed, anti-inflammatory activities, some classes of antimicrobial agent possess secondary anti-inflammatory properties, unrelated to their conventional antimicrobial activities, which target cells of the innate immune system, particularly neutrophils. This is a relatively uncommon, potentially beneficial property of antibiotics, which has been described for macrolides, imidazole anti-mycotics, fluoroquinolones, and tetracyclines. Although of largely unproven significance in the clinical setting, increasing awareness of the pro inflammatory and anti-inflammatory properties of antibiotics may contribute to a more discerning and effective use of these agents. PMID- 27713327 TI - Opportunities to Target Specific Contractile Abnormalities with Smooth Muscle Protein Kinase Inhibitors. AB - Smooth muscle is a major component of most hollow organ systems (e.g., airways, vasculature, bladder and gut/gastrointestine); therefore, the coordinated regulation of contraction is a key property of smooth muscle. When smooth muscle functions normally, it contributes to general health and wellness, but its dysfunction is associated with morbidity and mortality. Rho-associated protein kinase (ROCK) is central to calcium-independent, actomyosin-mediated contractile force generation in the vasculature, thereby playing a role in smooth muscle contraction, cell motility and adhesion. Recent evidence supports an important role for ROCK in the increased vasoconstriction and remodeling observed in various models of hypertension. This review will provide a commentary on the development of specific ROCK inhibitors and their clinical application. Fasudil will be discussed as an example of bench-to-bedside development of a clinical therapeutic that is used to treat conditions of vascular hypercontractility. Due to the wide spectrum of biological processes regulated by ROCK, many additional clinical indications might also benefit from ROCK inhibition. Apart from the importance of ROCK in smooth muscle contraction, a variety of other protein kinases are known to play similar roles in regulating contractile force. The zipper-interacting protein kinase (ZIPK) and integrin-linked kinase (ILK) are two well-described regulators of contraction. The relative contribution of each kinase to contraction depends on the muscle bed as well as hormonal and neuronal stimulation. Unfortunately, specific inhibitors for ZIPK and ILK are still in the development phase, but the success of fasudil suggests that inhibitors for these other kinases may also have valuable clinical applications. Notably, the directed inhibition of ZIPK with a pseudosubstrate molecule shows unexpected effects on the contractility of gastrointestinal smooth muscle. PMID- 27713328 TI - Aptamers for Targeted Drug Delivery. AB - Aptamers are a class of therapeutic oligonucleotides that form specific three dimensional structures that are dictated by their sequences. They are typically generated by an iterative screening process of complex nucleic acid libraries employing a process termed Systemic Evolution of Ligands by Exponential Enrichment (SELEX). SELEX has traditionally been performed using purified proteins, and cell surface receptors may be challenging to purify in their properly folded and modified conformations. Therefore, relatively few aptamers have been generated that bind cell surface receptors. However, improvements in recombinant fusion protein technology have increased the availability of receptor extracellular domains as purified protein targets, and the development of cell based selection techniques has allowed selection against surface proteins in their native configuration on the cell surface. With cell-based selection, a specific protein target is not always chosen, but selection is performed against a target cell type with the goal of letting the aptamer choose the target. Several studies have demonstrated that aptamers that bind cell surface receptors may have functions other than just blocking receptor-ligand interactions. All cell surface proteins cycle intracellularly to some extent, and many surface receptors are actively internalized in response to ligand binding. Therefore, aptamers that bind cell surface receptors have been exploited for the delivery of a variety of cargoes into cells. This review focuses on recent progress and current challenges in the field of aptamer-mediated delivery. PMID- 27713329 TI - The Pharmacogenomics of Anti-Hypertensive Therapy. AB - Hypertension is a major public health problem, but measures to reduce blood pressure and thus cardiovascular risk are complicated by the high prevalence of treatment resistance, despite the availability of multiple drugs. Drug side effects contribute considerably to suboptimal blood pressure control. Clinicians must often rely on empirical methods to match patients with effective drug treatment. Hypertension pharmacogenomics seeks to find genetic predictors of response to drugs that lower blood pressure and to translate this knowledge into clinical practice. In this review we summarise the current status of hypertension pharmacogenetics from monogenic hypertension to essential hypertension and discuss the issues that need to be considered in a hypertension pharmacogenomic study. PMID- 27713330 TI - Role of Leukotrienes and Leukotriene Modifiers in Asthma. AB - Leukotrienes (LTs), including cysteinyl LTs (CysLTs) and LTB4, are potent lipid mediators that are pivotal in the pathophysiology of asthma phenotypes. At least two receptor subtypes for CysLTs - CysLT1 and CysLT2 - have been identified. Most of the pathophysiological effects of CysLTs in asthma, including increased airway smooth muscle activity, microvascular permeability and airway mucus secretion, are mediated by the activation of the CysLT1 receptor. LTB4 may have a role in the development of airway hyperresponsiveness, severe asthma and asthma exacerbations. Although generally less effective than inhaled glucocorticoids, CysLT1 receptor antagonists can be given orally as monotherapy in patients with persistent mild asthma. In patients with more severe asthma, CysLT1 receptor antagonists can be combined with inhaled glucocorticoids. This therapeutic strategy improves asthma control and enables the dose of inhaled glucocorticoids to be reduced, while maintaining similar efficacy. The identification of subgroups of patients with asthma who respond to CysLT1 receptor antagonists is relevant for asthma management, as the response to these drugs is variable. The potential anti-remodeling effect of CysLT1 receptor antagonists might be important for preventing or reversing airway structural changes in patients with asthma. This review discusses the role of LTs in asthma and the therapeutic implications of the pharmacological modulation of the LT pathway for asthma. PMID- 27713333 TI - In Response to: 'Impact of Glycosylation on Effector Functions of Therapeutic IgG' (Pharmaceuticals 2010, 3, 146-157). AB - To complete the review article by Abes and colleagues (Pharmaceuticals 2010, 3, 146-157) which provides a good overview on recently developed approaches for generation of glyco-modified antibodies and the impact of glyco-modification of antibodies on their effector functions, important information should be added, namely that - besides the Glycart and the Biowa approach to generate de fucosylated antibodies - innovative, moss derived methods have been shown to generate glyco-modified antibodies with improved effector function profile. PMID- 27713332 TI - Use of p38 MAPK Inhibitors for the Treatment of Werner Syndrome. AB - Werner syndrome provides a convincing model for aspects of the normal ageing phenotype and may provide a suitable model for therapeutic interventions designed to combat the ageing process. Cultured primary fibroblast cells from Werner syndrome patients provide a powerful model system to study the link between replicative senescence in vitro and in vivo pathophysiology. Genome instability, together with an increased pro-oxidant state, and frequent replication fork stalling, all provide plausible triggers for intracellular stress in Werner syndrome cells, and implicates p38 MAPK signaling in their shortened replicative lifespan. A number of different p38 MAPK inhibitor chemotypes have been prepared rapidly and efficiently using microwave heating techniques for biological study in Werner syndrome cells, including SB203580, VX-745, RO3201195, UR-13756 and BIRB 796, and their selectivity and potency evaluated in this cellular context. Werner syndrome fibroblasts treated with a p38 MAPK inhibitor reveal an unexpected reversal of the accelerated ageing phenotype. Thus the study of p38 inhibition and its effect upon Werner pathophysiology is likely to provide new revelations into the biological mechanisms operating in cellular senescence and human ageing in the future. PMID- 27713334 TI - A Review of Topical Diclofenac Use in Musculoskeletal Disease. AB - Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed medications for the treatment of musculoskeletal disorders. Osteoarthritis is the most common form of arthritis in humans and its prevalence rises with age. Oral NSAIDs have potential associated toxicities that must be monitored for and can limit the use of these drugs in certain populations including people of older age. Topical NSAIDs are now being recognized as an option for the treatment strategy of osteoarthritis. We review the efficacy and safety of one of the most common topical NSAIDS, topical diclofenac, for the treatment of osteoarthritis. PMID- 27713331 TI - Non-Steroidal Anti-Inflammatory Drugs in Alzheimer's Disease and Parkinson's Disease: Reconsidering the Role of Neuroinflammation. AB - Alzheimer's disease (AD) and Parkinson's disease (PD) are the most common neurodegenerative diseases with age as the greatest risk factor. As the general population experiences extended life span, preparation for the prevention and treatment of these and other age-associated neurological diseases are warranted. Since epidemiological studies suggested that non-steroidal anti-inflammatory drug (NSAID) use decreased risk for AD and PD, increasing attention has been devoted to understanding the costs and benefits of the innate neuroinflammatory response to functional recovery following pathology onset. This review will provide a general overview on the role of neuroinflammation in these neurodegenerative diseases and an update on NSAID treatment in recent experimental animal models, epidemiological analyses, and clinical trials. PMID- 27713335 TI - Unlocking the Door to Neuronal Woes in Alzheimer's Disease: Abeta and Mitochondrial Permeability Transition Pore. AB - Mitochondrial dysfunction occurs early in the progression of Alzheimer's disease. Amyloid-beta peptide has deleterious effects on mitochondrial function and contributes to energy failure, respiratory chain impairment, neuronal apoptosis, and generation of reactive oxygen species in Alzheimer's disease. The mechanisms underlying amyloid-beta induced mitochondrial stress remain unclear. Emerging evidence indicates that mitochondrial permeability transition pore is important for maintenance of mitochondrial and neuronal function in aging and neurodegenerative disease. Cyclophilin D (Cyp D) plays a central role in opening mitochondrial permeability transition pores, ultimately leading to cell death. Interaction of amyloid-beta with cyclophilin D triggers or enhances the formation of mitochondrial permeability transition pores, consequently exacerbating mitochondrial and neuronal dysfunction, as shown by decreased mitochondrial membrane potential, impaired mitochondrial respiration function, and increased oxidative stress and cytochrome c release. Blockade of cyclophilin D by genetic abrogation or pharmacologic inhibition protects mitochondria and neurons from amyloid-beta induced toxicity, suggesting that cyclophilin D dependent mitochondrial transition pores are a therapeutic target for Alzheimer's disease. PMID- 27713336 TI - Non-Steroidal Anti-Inflammatory Drugs and Brain Inflammation: Effects on Microglial Functions. AB - The term NSAID refers to structurally diverse chemical compounds that share the ability to inhibit the activity of the prostaglandin (PG) biosynthetic enzymes, the cyclooxygenase (COX) isoforms 1 and 2. The suppression of PG synthesis at sites of inflammation has been regarded as primarily responsible for the beneficial properties of NSAIDs, but several COX-independent effects have been described in recent years. Epidemiological studies indicate that NSAIDs are neuroprotective, although the mechanisms underlying their beneficial effect remain largely unknown. Microglial cells play a major role in brain inflammation and are often viewed as major contributors to the neurodegeneration. Therefore, microglia represent a likely target for NSAIDs within the brain. In the present review, we focused on the direct effects of NSAIDs and selective COX-2 inhibitors on microglial functions and discuss the potential efficacy in controlling brain inflammation. PMID- 27713338 TI - Linezolid Resistance in Staphylococci. AB - Linezolid, the first oxazolidinone to be used clinically, is effective in the treatment of infections caused by various Gram-positive pathogens, including multidrug resistant enterococci and methicillin-resistant Staphylococus aureus. It has been used successfully for the treatment of patients with endocarditis and bacteraemia, osteomyelitis, joint infections and tuberculosis and it is often used for treatment of complicated infections when other therapies have failed. Linezolid resistance in Gram-positive cocci has been encountered clinically as well as in vitro, but it is still a rare phenomenon. The resistance to this antibiotic has been, until now, entirely associated with distinct nucleotide substitutions in domain V of the 23S rRNA genes. The number of mutated rRNA genes depends on the dose and duration of linezolid exposure and has been shown to influence the level of linezolid resistance. Mutations in associated ribosomal proteins also affect linezolid activity. A new phenicol and clindamycin resistance phenotype has recently been found to be caused by an RNA methyltransferase designated Cfr. This gene confers resistance to lincosamides, oxazolidinones, streptogramin A, phenicols and pleuromutilins, decrease the susceptibility of S. aureus to tylosin, to josamycin and spiramycin and thus differs from erm rRNA methylase genes. Research into new oxazolidinones with improved characteristics is ongoing. Data reported in patent applications demonstrated that some oxazolidinone derivatives, also with improved characteristics with respect to linezolid, are presently under study: at least three of them are in an advanced phase of development. PMID- 27713337 TI - NSAIDs in the Acute Treatment of Migraine: A Review of Clinical and Experimental Data. AB - Migraine is a common disabling neurological disorder with a serious socio economical burden. By blocking cyclooxygenase nonsteroidal anti-inflammatory drugs (NSAIDs) decrease the synthesis of prostaglandins, which are involved in the pathophysiology of migraine headaches. Despite the introduction more than a decade ago of a new class of migraine-specific drugs with superior efficacy, the triptans, NSAIDs remain the most commonly used therapies for the migraine attack. This is in part due to their wide availability as over-the-counter drugs and their pharmaco-economic advantages, but also to a favorable efficacy/side effect profile at least in attacks of mild and moderate intensity. We summarize here both the experimental data showing that NSAIDs are able to influence several pathophysiological facets of the migraine headache and the clinical studies providing evidence for the therapeutic efficacy of various subclasses of NSAIDs in migraine therapy. Taken together these data indicate that there are several targets for NSAIDs in migraine pathophysiology and that on the spectrum of clinical potency acetaminophen is at the lower end while ibuprofen is among the most effective drugs. Acetaminophen and aspirin excluded, comparative trials between the other NSAIDs are missing. Since evidence-based criteria are scarce, the selection of an NSAID should take into account proof and degree of efficacy, rapid GI absorption, gastric ulcer risk and previous experience of each individual patient. If selected and prescribed wisely, NSAIDs are precious, safe and cost-efficient drugs for the treatment of migraine attacks. PMID- 27713339 TI - NSAIDs and Cell Proliferation in Colorectal Cancer. AB - Colon cancer is common worldwide and accounts for significant morbidity and mortality in patients. Fortunately, epidemiological studies have demonstrated that continuous therapy with NSAIDs offers real promise of chemoprevention and adjunct therapy for colon cancer patients. Tumour growth is the result of complex regulation that determines the balance between cell proliferation and cell death. How NSAIDs affect this balance is important for understanding and improving treatment strategies and drug effectiveness. NSAIDs inhibit proliferation and impair the growth of colon cancer cell lines when tested in culture in vitro and many NSAIDs also prevent tumorigenesis and reduce tumour growth in animal models and in patients, but the relationship to inhibition of tumour cell proliferation is less convincing, principally due to gaps in the available data. High concentrations of NSAIDs are required in vitro to achieve cancer cell inhibition and growth retardation at varying time-points following treatment. However, the results from studies with colon cancer cell xenografts are promising and, together with better comparative data on anti-proliferative NSAID concentrations and doses (for in vitro and in vivo administration), could provide more information to improve our understanding of the relationships between these agents, dose and dosing regimen, and cellular environment. PMID- 27713341 TI - Phospholipase D2 Enhances Epidermal Growth Factor-Induced Akt Activation in EL4 Lymphoma Cells. AB - Phospholipase D2 (PLD2) generates phosphatidic acid through hydrolysis of phosphatidylcholine. PLD2 has been shown to play a role in enhancing tumorigenesis. The epidermal growth factor receptor (EGFR) can both activate and interact with PLD2. Murine lymphoma EL4 cells lacking endogenous PLD2 present a unique model to elucidate the role of PLD2 in signal transduction. In the current study, we investigated effects of PLD2 on EGF response. Western blotting and RT PCR were used to establish that both parental cells and PLD2 transfectants express endogenous EGFR. Levels of EGFR protein are increased in cells expressing active PLD2, as compared to parental cells or cells expressing inactive PLD2. EGF stimulates proliferation of EL4 cells transfected with active PLD2, but not parental cells or cells transfected with inactive PLD2. EGF-mediated proliferation in cells expressing active PLD2 is dependent on the activities of both the EGFR and the PI3K/Akt pathway, as demonstrated by studies using protein kinase inhibitors. EGF-induced invasion through a synthetic extracellular matrix is enhanced in cells expressing active PLD2, as compared to parental cells or cells expressing inactive PLD2. Taken together, the data suggest that PLD2 acts in concert with EGFR to enhance mitogenesis and invasion in lymphoma cells. PMID- 27713340 TI - Demethylating Agents in the Treatment of Cancer. AB - Gene silencing resulting from aberrant DNA methylation can lead to tumorigenesis. Therefore, drugs that inhibit or interfere with DNA methylation have been used to reactivate and induce silenced gene re-expression in malignancies. Two demethylating agents, azacitidine and decitabine, are approved for the treatment of myelodysplastic syndromes (MDS) by the U.S. Food and Drug Administration (FDA), and are now considered the standard of care in MDS. In this review, we discuss clinical data, including clinical benefits and toxicities, which led to the approval of azacitidine and decitabine. We also summarize findings from clinical trials that used these two demethylating agents in the treatment of solid tumors. Lastly, we discuss some limitations in the use of azacitidine and decitabine in cancer therapy. PMID- 27713343 TI - Role of Non-Steroidal Anti-Inflammatory Drugs in Gynecology. AB - This review summarizes the current use of non-steroidal anti-inflammatory drugs (NSAIDs) in obstetrics, gynecology and infertility. These medications are commonly used in different fields of reproductive medicine, for pain management after operative procedures and to relieve dysmenorrhea. In addition to their analgesic effect, NSAIDs are helpful in the management of menorrhagia by decreasing menstrual blood loss. NSAIDs alleviate pain associated with medical abortion, assist in undertaking natural cycle in-vitro fertilization by preventing follicular rupture and reducing premature ovulation, and serve as tocolytics in preterm labor. New NSAIDs may have a growing role in management of women's health. PMID- 27713342 TI - In Silico Screening of Nonsteroidal Anti-Inflammatory Drugs and Their Combined Action on Prostaglandin H Synthase-1. AB - The detailed kinetic model of Prostaglandin H Synthase-1 (PGHS-1) was applied to in silico screening of dose-dependencies for the different types of nonsteroidal anti-inflammatory drugs (NSAIDs), such as: reversible/irreversible, nonselective/selective to PGHS-1/PGHS-2 and time dependent/independent inhibitors (aspirin, ibuprofen, celecoxib, etc.) The computational screening has shown a significant variability in the IC50s of the same drug, depending on different in vitro and in vivo experimental conditions. To study this high heterogeneity in the inhibitory effects of NSAIDs, we have developed an in silico approach to evaluate NSAID action on targets under different PGHS-1 microenvironmental conditions, such as arachidonic acid, reducing cofactor, and peroxide concentrations. The designed technique permits translating the drug IC50, obtained in one experimental setting to another, and predicts in vivo inhibitory effects based on the relevant in vitro data. For the aspirin case, we elucidated the mechanism underlying the enhancement and reduction (aspirin resistance) of its efficacy, depending on PGHS-1 microenvironment in in vitro/in vivo experimental settings. We also present the results of the in silico screening of the combined action of sets of two NSAIDs (aspirin with ibuprofen, aspirin with celecoxib), and study the mechanism of the experimentally observed effect of the suppression of aspirin-mediated PGHS-1 inhibition by selective and nonselective NSAIDs. Furthermore, we discuss the applications of the obtained results to the problems of standardization of NSAID test assay, dependence of the NSAID efficacy on cellular environment of PGHS-1, drug resistance, and NSAID combination therapy. PMID- 27713344 TI - Difficulties in Treatment and Management of Epilepsy and Challenges in New Drug Development. AB - Epilepsy is a serious neurological disorder that affects around 50 million people worldwide. Almost 30% of epileptic patients suffer from pharmacoresistance, which is associated with social isolation, dependent behaviour, low marriage rates, unemployment, psychological issues and reduced quality of life. Currently available antiepileptic drugs have a limited efficacy, and their negative properties limit their use and cause difficulties in patient management. Antiepileptic drugs can provide only symptomatic relief as these drugs suppress seizures but do not have ability to cure epileptogenesis. The long term use of antiepileptic drugs is limited due to their adverse effects, withdrawal symptoms, deleterious interactions with other drugs and economic burden, especially in developing countries. Furthermore, some of the available antiepileptic drugs may even potentiate certain type of seizures. Several in vivo and in vitro animal models have been proposed and many new antiepileptic drugs have been marketed recently, but large numbers of patients are still pharmacoresistant. This review will highlight the difficulties in treatment and management of epilepsy and the limitations of available antiepileptic drugs and animal seizure models. PMID- 27713346 TI - Non-Steroidal Anti-Inflammatory Drugs: An Overview of Cardiovascular Risks. AB - While aspirin may offer protection, other non-aspirin non-steroidal anti inflammatory drugs (NSAIDs) can cause serious cardiovascular side effects and complications. This has led to a general "black box" warning for cardiovascular adverse events for NSAIDs. This review explores the different mechanisms underlying the protective effects of aspirin, the NSAID associated renovascular effects causing hypertension, edema and heart failure, the cardiovascular effects causing myocardial infarction and stroke, and the possible deleterious interaction between NSAIDs and aspirin. PMID- 27713347 TI - Cannabinoid-Induced Hyperemesis: A Conundrum-From Clinical Recognition to Basic Science Mechanisms. AB - Cannabinoids are used clinically on a subacute basis as prophylactic agonist antiemetics for the prevention of nausea and vomiting caused by chemotherapeutics. Cannabinoids prevent vomiting by inhibition of release of emetic neurotransmitters via stimulation of presynaptic cannabinoid CB1 receptors. Cannabis-induced hyperemesis is a recently recognized syndrome associated with chronic cannabis use. It is characterized by repeated cyclical vomiting and learned compulsive hot water bathing behavior. Although considered rare, recent international publications of numerous case reports suggest the contrary. The syndrome appears to be a paradox and the pathophysiological mechanism(s) underlying the induced vomiting remains unknown. Although some traditional hypotheses have already been proposed, the present review critically explores the basic science of these explanations in the clinical setting and provides more current mechanisms for the induced hyperemesis. These encompass: (1) pharmacokinetic factors such as long half-life, chronic exposure, lipid solubility, individual variation in metabolism/excretion leading to accumulation of emetogenic cannabinoid metabolites, and/or cannabinoid withdrawal; and (2) pharmacodynamic factors including switching of the efficacy of Delta8-THC from partial agonist to antagonist, differential interaction of Delta8-THC with Gs and Gi signal transduction proteins, CB1 receptor desensitization or downregulation, alterations in tissue concentrations of endocannabinoid agonists/inverse agonists, Delta8-THC-induced mobilization of emetogenic metabolites of the arachidonic acid cascade, brainstem versus enteric actions of Delta8-THC, and/or hypothermic versus hyperthermic actions of Delta8-THC. In addition, human and animal findings suggest that chronic exposure to cannabis may not be a prerequisite for the induction of vomiting but is required for the intensity of emesis. PMID- 27713348 TI - The Molecular Mechanisms of Anesthetic Action: Updates and Cutting Edge Developments from the Field of Molecular Modeling. AB - For over 160 years, general anesthetics have been given for the relief of pain and suffering. While many theories of anesthetic action have been purported, it has become increasingly apparent that a significant molecular focus of anesthetic action lies within the family of ligand-gated ion channels (LGIC's). These protein channels have a transmembrane region that is composed of a pentamer of four helix bundles, symmetrically arranged around a central pore for ion passage. While initial and some current models suggest a possible cavity for binding within this four helix bundle, newer calculations postulate that the actual cavity for anesthetic binding may exist between four helix bundles. In either scenario, these cavities have a transmembrane mode of access and may be partially bordered by lipid moieties. Their physicochemical nature is amphiphilic. Anesthetic binding may alter the overall motion of a ligand-gated ion channel by a "foot-in-door" motif, resulting in the higher likelihood of and greater time spent in a specific channel state. The overall gating motion of these channels is consistent with that shown in normal mode analyses carried out both in vacuo as well as in explicitly hydrated lipid bilayer models. Molecular docking and large scale molecular dynamics calculations may now begin to show a more exact mode by which anesthetic molecules actually localize themselves and bind to specific protein sites within LGIC's, making the design of future improvements to anesthetic ligands a more realizable possibility. PMID- 27713345 TI - Protein Kinases as Drug Development Targets for Heart Disease Therapy. AB - Protein kinases are intimately integrated in different signal transduction pathways for the regulation of cardiac function in both health and disease. Protein kinase A (PKA), Ca2+-calmodulin-dependent protein kinase (CaMK), protein kinase C (PKC), phosphoinositide 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) are not only involved in the control of subcellular activities for maintaining cardiac function, but also participate in the development of cardiac dysfunction in cardiac hypertrophy, diabetic cardiomyopathy, myocardial infarction, and heart failure. Although all these kinases serve as signal transducing proteins by phosphorylating different sites in cardiomyocytes, some of their effects are cardioprotective whereas others are detrimental. Such opposing effects of each signal transduction pathway seem to depend upon the duration and intensity of stimulus as well as the type of kinase isoform for each kinase. In view of the fact that most of these kinases are activated in heart disease and their inhibition has been shown to improve cardiac function, it is suggested that these kinases form excellent targets for drug development for therapy of heart disease. PMID- 27713349 TI - Therapeutic Potential of Non-Psychotropic Cannabidiol in Ischemic Stroke. AB - Cannabis contains the psychoactive component delta8-tetrahydrocannabinol (delta8 THC), and the non-psychoactive components cannabidiol (CBD), cannabinol, and cannabigerol. It is well-known that delta8-THC and other cannabinoid CB1 receptor agonists are neuroprotective during global and focal ischemic injury. Additionally, delta8-THC also mediates psychological effects through the activation of the CB1 receptor in the central nervous system. In addition to the CB1 receptor agonists, cannabis also contains therapeutically active components which are CB1 receptor independent. Of the CB1 receptor-independent cannabis, the most important is CBD. In the past five years, an increasing number of publications have focused on the discovery of the anti-inflammatory, anti oxidant, and neuroprotective effects of CBD. In particular, CBD exerts positive pharmacological effects in ischemic stroke and other chronic diseases, including Parkinson's disease, Alzheimer's disease, and rheumatoid arthritis. The cerebroprotective action of CBD is CB1 receptor-independent, long-lasting, and has potent anti-oxidant activity. Importantly, CBD use does not lead to tolerance. In this review, we will discuss the therapeutic possibility of CBD as a cerebroprotective agent, highlighting recent pharmacological advances, novel mechanisms, and therapeutic time window of CBD in ischemic stroke. PMID- 27713350 TI - High-Dose Ibuprofen in Cystic Fibrosis. AB - Cystic Fibrosis (CF) is the most common lethal genetic disorder in North America and Europe. Most patients succumb to progressive lung disease characterized by an exaggerated neutrophilic inflammation. In animal models of chronic infection, high-dose ibuprofen was demonstrated to reduce inflammation without hindering bacterial clearance. This led to two clinical trials, which demonstrated a benefit in slowing the progression of lung disease in CF. However, concerns about potential adverse effects have limited the use of high-dose ibuprofen in CF patients. There are a variety of potential mechanisms to account for the observed clinical benefit. A better understanding of these mechanisms could potentially lead to more targeted and better-tolerated anti-inflammatory therapies. PMID- 27713351 TI - Nonsteroidal Anti-Inflammatory Drug-Induced Gastroduodenal Bleeding: Risk Factors and Prevention Strategies. AB - Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most widely prescribed medications in the World. A frequent complication of NSAID use is gastroduodenal bleeding. Risk factors for gastroduodenal bleeding while on NSAID therapy are age, prior peptic ulcer and co-medication with anti-platelet agents, anticoagulants, glucocorticosteroids and selective serotonin-reuptake inhibitors (SSRI). Prevention strategies for at-risk patients include the use of the lowest effective dose of NSAIDs, co-therapy with proton-pump inhibitors and/or the use of a COX-2 selective agent. Treatment of Helicobacter pylori infection is beneficial for primary prophylaxis of NSAID-induced gastroduodenal bleeding in NSAID-naive patients. For patients with cardiovascular risk factors requiring NSAIDs, naproxen should be selected. In very high risk patients for both gastrointestinal and cardiovascular complications NSAID therapy should be avoided altogether. PMID- 27713352 TI - EGFR Targeting in Hormone-Refractory Prostate Cancer: Current Appraisal and Prospects for Treatment. AB - The incidence of prostate cancer increases with age and because of its high prevalence this disease has become a major public health concern. Despite advances in our understanding of the biological mechanisms responsible for the development of this cancer, the transition to the hormone refractory stage (HRPC) and metastatic progression pose real problems of clinical management. Currently, docetaxel chemotherapy has been shown to have a slight but significant impact on survival, though the gain in median survival is still less than three months. Research is therefore continuing to improve treatment outcomes. The progression of prostate cancer is accompanied by the overexpression of EGFR (epidermal growth factor receptor) in a very large majority of cases, suggesting that this may play a mechanistic role. Unfortunately, although preclinical findings seem to be promising for therapies targeting the EGFR in HRPC, current clinical results are disappointing. These results should however encourage us to look for different ways of using anti-EGFR agents or combining them with other targeted therapies. PMID- 27713353 TI - Emerging Families of Ion Channels Involved in Urinary Bladder Nociception. AB - The expression of multiple ion channels and receptors is essential for nociceptors to detect noxious stimuli of a thermal, mechanical or chemical nature. The peripheral sensory transduction systems of the urinary bladder include sensory nerve endings, urothelial cells and others whose location is suitable for transducing mechanical and chemical stimuli. There is an increasing body of evidence implicating the Deg/ENaC and TRP channel families in the control of bladder afferent excitability under physiological and pathological conditions. Pharmacological interventions targeting these ion channels may provide a new strategy for the treatment of pathological bladder sensation and pain. PMID- 27713355 TI - Artesunate: The Best Drug in the Treatment of Severe and Complicated Malaria. AB - This review summarizes progress in treating severe and complicated malaria, which are global problems, claiming at least one million lives annually, and have been accompanied by advances in our understanding of the pathogenesis of severe malaria complications. New drugs such as intravenous artesunate (AS) and intramuscular artemether (AM) are improving outcomes and decreasing malaria deaths. Trials comparing AM to the traditional parenteral drug, quinine, have not demonstrated however convincing evidence of a mortality advantage for AM. The South East Asian Quinine Artesunate Malaria Trials (SEAQUAMAT), a multicenter, randomized, open-label study comparing AS with quinine showed that parenteral AS was shown to be associated with a 35% reduction in the risk of mortality compare to quinine, and is now the recommended treatment by the WHO for severe and complicated malaria in low-transmission areas and in the second and third trimesters of pregnancy, with almost all the benefit reported in those with high parasite counts. Artesunate is a semisynthetic derivative of artemisinin whose water solubility facilitates absorption and provides an advantage over other artemisinins because it can be formulated as oral, rectal, intramuscular, and intravenous preparations. Artesunate is rapidly hydrolyzed to dihydroartemisinin, which is the most active schizonticidal metabolite. Injectable AS results in a more rapid systemic availability of AS compared with intramuscular AM. This pharmacokinetic advantage may provide a clinical advantage in the treatments of severe and complicated malaria. PMID- 27713354 TI - Nonsteroidal Anti-Inflammatory Drugs and the Kidney. AB - Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit the isoenzymes COX-1 and COX-2 of cyclooxygenase (COX). Renal side effects (e.g., kidney function, fluid and urinary electrolyte excretion) vary with the extent of COX-2-COX-1 selectivity and the administered dose of these compounds. While young healthy subjects will rarely experience adverse renal effects with the use of NSAIDs, elderly patients and those with co-morbibity (e.g., congestive heart failure, liver cirrhosis or chronic kidney disease) and drug combinations (e.g., renin angiotensin blockers, diuretics plus NSAIDs) may develop acute renal failure. This review summarizes our present knowledge how traditional NSAIDs and selective COX-2 inhibitors may affect the kidney under various experimental and clinical conditions, and how these drugs may influence renal inflammation, water transport, sodium and potassium balance and how renal dysfunction or hypertension may result. PMID- 27713357 TI - Rational Polytherapy with Antiepileptic Drugs. AB - Approximately 30-40% of patients do not achieve seizure control with a single antiepileptic drug (AED). With the advent of multiple AEDs in the past 15 years, rational polytherapy, the goal of finding combinations of AEDs that have favorable characteristics, has become of greater importance. We review the theoretical considerations based on AED mechanism of action, animal models, human studies in this field, and the challenges in finding such optimal combinations. Several case scenarios are presented, illustrating examples of rational polytherapy. PMID- 27713358 TI - Rational Use of Antibiotics in the Treatment of Functional Bowel Disorders. AB - Functional gastrointestinal symptoms such us bloating, fullness, flatulence, diarrhea, and constipation due to irritable bowel syndrome (IBS) were recently attributed to small bowel bacterial overgrowth, a condition depending on the presence of an increased number of bacteria in the small bowel. However, the methodology used to describe this association may be harshly criticized, since it has already been shown to be quite inaccurate. As a result an inappropriate use of antibiotics was consequently generated. In fact, antibiotics could be effective in the treatment of functional complaints, but only in a limited subgroup of patients, characterized by an increase of fermentation at colonic level. In this review, we have examined the papers suggesting a pathophysiological link between IBS and small bowel bacterial overgrowth, underlining its inappropriateness, and put forth our personal view on the rationale for antibiotic use in IBS. PMID- 27713359 TI - Measurement of Neuropsychiatric Symptoms in Clinical Trials Targeting Alzheimer's Disease and Related Disorders. AB - Behavioral and psychological symptoms (BPSD) are now known to be frequently associated to cognitive and functional decline in Alzheimer's disease and related disorders. They are present since the early stages of the disease and have negative impact on the disease process. BPSD assessment is crucial in clinical practice and also in future clinical trials targeting disease-modifying therapies for dementia. In this article, we will first review current assessment tools for BPSD, mainly global and domain-specific scales, and new assessment methods, currently available or in development, including new scales, diagnostic criteria and new technologies such as ambulatory actigraphy. PMID- 27713356 TI - The Health Effect of Psychostimulants: A Literature Review. AB - Prevalence of psychostimulant use is high, and raising in several countries. Nicotine is the legal stimulant causing the most important public health impact. Cocaine ranks among the most used illicit substances after cannabis. Stimulant medications are frequently misused. Psychostimulants can lead to addiction, have physical, psychological and social health consequences and can induce a great disease burden. The aim of the present article is to provide a literature review on the health effects of stimulants as potential drugs of abuse. It will cover essentially cocaine, amphetamines and its derivatives (including methamphetamines and 3-4-methylenedioxymethamphetamine, ecstasy), nicotine, caffeine and khat, and touch upon the issues of prescribed substances (anti-depressants, weight control medications, attention-deficit hyperactivity disorder medications, hypersomniac disorder). Their pharmacology, addictive potential, health consequences and treatment will be discussed. We used Medline for the literature review from 1990 to the date of this review, and mention the findings of human and animal studies (the latter only if they are of clinical relevance). PMID- 27713361 TI - Synthesis and Antimicrobial Activity of Some New Quinoxaline Derivatives. AB - 2-Chloro-3-methylquinoxaline was selected as a nucleus around which various molecular transformations were performed to obtain new compounds expected to possess optimized antimicrobial activity. As very little work regarding attachment of ether linkages replacing chlorine at C-2 has been reported, it was thought worthwhile to synthesize various quinoxaline derivatives by replacing the C2 chlorine with an ether linkage attached to a benzene ring possessing an aldehyde or a free amino group which can be further reacted with aromatic amines and aromatic aldehydes, respectively, to yield new Schiff bases containing quinoxaline moieties. Thus the compounds 4-(2-methylquinoxalinyloxy) benzaldehyde (4), 2-[4-(substituted-benziminomethyl)-phenoxy]-3-methyl quinoxalines 5a-e, 4-(2 methyl-quinoxaline-3-yloxy)benzamine (6) and 4-(2-methylquinoxalin-3-yloxy)-N substituted benzylidine benzamines 7a-e were synthesized and tested for their antimicrobial activity. The structures of the compounds were confirmed on the basis of their elemental and spectral data. PMID- 27713360 TI - Combinations of drugs in the Treatment of Obesity. AB - Obesity is a chronic disease associated with excess morbidity and mortality. Clinical treatment, however, currently offers disappointing results, with very high rates of weight loss failure or weight regain cycles, and only two drugs (orlistat and sibutramine) approved for long-term use. Drugs combinations can be an option for its treatment but, although widely used in clinical practice, very few data are available in literature for its validation. Our review focuses on the rationale for their use, with advantages and disadvantages; on combinations often used, with or without studies; and on new perspectives of combinations being studied mainly by the pharmaceutical industry. PMID- 27713362 TI - The Impact of Residual Symptoms in Major Depression. AB - The current definition of remission from major depressive disorder does not fully take into account all aspects of patient recovery. Residual symptoms of depression are very common in patients who are classified as being in remission. Patients with residual symptoms are at increased risk of functional and interpersonal impairments, and are at high risk for recurrence of depression. This article discusses the incidence of residual symptoms of depression, as well as the risks and consequences of these symptoms, and will review the state of current treatment. PMID- 27713363 TI - Use of Generics-A Critical Cost Containment Measure for All Healthcare Professionals in Europe? AB - Pharmaceutical expenditures in ambulatory care rose rapidly in Europe in the 1990s and early 2000s. This was typically faster than other components of healthcare spending, leading to reforms to moderate future growth. A number of these centered on generic medicines with measures to lower reimbursed prices as well as enhance their prescribing and dispensing. The principal objective of this paper is to review additional measures that some European countries can adopt to further reduce reimbursed prices for generics. Secondly, potential approaches to address concerns with generics when they arise to maximize savings. Measures to enhance the prescribing of generics will also briefly be discussed. A narrative review of the extensive number of publications and associated references from the co-authors was conducted supplemented with known internal or web-based articles. In addition, health authority and health insurance databases, principally from 2001 to 2007, were analyzed to assess the impact of the various measures on price reductions for generic omeprazole and generic simvastatin vs. pre-patent loss prices, as well as overall efficiency in Proton Pump Inhibitor (PPI) and statin prescribing. The various initiatives generally resulted in considerable lowering of the prices of generics as well as specifically for generic omeprazole and generic simvastatin vs. pre-patent loss prices. At one stage in the UK, generic simvastatin was just 2% of the originator price. These measures also led to increased efficiency for PPI and statin prescribing with reimbursed expenditure for the PPIs and statins either falling or increasing at appreciably lower rates than increases in utilization. A number of strategies have also been introduced to address patient and physician concerns with generics to maximize savings. In conclusion, whilst recent reforms have been successful, European countries must continue learning from each other to fund increased volumes and new innovative drugs as resource pressures grow. Policies regarding generics and their subsequent impact on reimbursement and utilization of single sourced products will continue to play a key role to release valuable resources. However, there must continue to be strategies to address concerns with generics when they exist.

AB - It is estimated that underlying infections and inflammatory responses are linked to 15-20% of all deaths from cancer worldwide. Inflammation is a physiologic process in response to tissue damage resulting from microbial pathogen infection, chemical irritation, and/or wounding. Tissues injured throughout the recruitment of inflammatory cells such as macrophages and neutrophils, generate a great amount of growth factors, cytokines, and reactive oxygen and nitrogen species that may cause DNA damage that in turn predisposes to the transformation from chronic inflammation to neoplasia. Cyclooxygenase (COX), playing a key role in cell homeostasis, angiogenesis and tumourigenesis, may represent the link between inflammation and cancer. Currently COX is becoming a pharmacological target for cancer prevention and treatment.It is estimated that underlying infections and inflammatory responses are linked to 15-20% of all deaths from cancer worldwide.

AB - Exenatide is a GLP-1 (glucagon-like peptide-1) agonist that has been approved in the UK for use in the management of Type 2 Diabetes Mellitus (T2DM) since 2006. It acts by increasing glucose-induced insulin release and by reducing glucagon secretion postprandially. It therefore increases insulin secretion and reduces glucose levels, especially postprandially. It also reduces gastric emptying and acts centrally to promote satiety. In clinical practice it reduces HbA1c (range; 0.4% to -1.3%), fasting and postprandial blood glucose levels and is the only antidiabetic agent (together with liraglutide; a human GLP-1 analogue) to promote weight loss (range; -1.5 kg to -5.5 kg). It can be used as monotherapy or in combination with metformin and/or sulphonylureas (SU) and/or thiazolinediones (TZD). When compared with insulin it causes similar reductions in HbA1c and glucose levels, but unlike insulin it has the advantage of inducing weight loss. Its main side effect is gastrointestinal (GI) disturbances; nausea is the commonest GI adverse effect, albeit usually mild and transient. Hypoglycaemia is uncommon, especially when used as monotherapy or in combination with metformin. In this review article we scrutinize the currently available evidence for use of exenatide in the management of T2DM. PMID- 27713367 TI - Clinical Pharmacokinetics of Penicillins, Cephalosporins and Aminoglycosides in the Neonate: A Review. AB - Bacterial infections are common in the neonates and are a major cause of morbidity and mortality. Sixty percent of preterm infants admitted to neonatal intensive care units received at least one antibiotic during the first week of life. Penicillins, aminoglycosides and cephalosporins comprised 53, 43 and 16%, respectively. Kinetic parameters such as the half-life (t1/2), clearance (Cl), and volume of distribution (Vd) change with development, so the kinetics of penicillins, cephalosporins and aminoglycosides need to be studied in order to optimise therapy with these drugs. The aim of this study is to review the pharmacokinetics of penicillins, cephalosporins and aminoglycosides in the neonate in a single article in order to provide a critical analysis of the literature and thus provide a useful tool in the hands of physicians. The bibliographic search was performed electronically using PubMed, as the search engine, until February 2nd, 2010. Medline search terms were as follows: pharmacokinetics AND (penicillins OR cephalosporins OR aminoglycosides) AND infant, newborn, limiting to humans. Penicillins, cephalosporins and aminoglycosides are fairly water soluble and are mainly eliminated by the kidneys. The maturation of the kidneys governs the pharmacokinetics of penicillins, cephalosporins and aminoglycosides in the neonate. The renal excretory function is reduced in preterms compared to term infants and Cl of these drugs is reduced in premature infants. Gestational and postnatal ages are important factors in the maturation of the neonate and, as these ages proceed, Cl of penicillins, cephalosporins and aminoglycosides increases. Cl and t1/2 are influenced by development and this must be taken into consideration when planning a dosage regimen with these drugs. More pharmacokinetic studies are required to ensure that the dose recommended for the treatment of sepsis in the neonate is evidence based. PMID- 27713365 TI - Brain CB2 Receptors: Implications for Neuropsychiatric Disorders. AB - Although previously thought of as the peripheral cannabinoid receptor, it is now accepted that the CB2 receptor is expressed in the central nervous system on microglia, astrocytes and subpopulations of neurons. Expression of the CB2 receptor in the brain is significantly lower than that of the CB1 receptor. Conflicting findings have been reported on the neurological effects of pharmacological agents targeting the CB2 receptor under normal conditions. Under inflammatory conditions, CB2 receptor expression in the brain is enhanced and CB2 receptor agonists exhibit potent anti-inflammatory effects. These findings have prompted research into the CB2 receptor as a possible target for the treatment of neuroinflammatory and neurodegenerative disorders. Neuroinflammatory alterations are also associated with neuropsychiatric disorders and polymorphisms in the CB2 gene have been reported in depression, eating disorders and schizophrenia. This review will examine the evidence to date for a role of brain CB2 receptors in neuropsychiatric disorders. PMID- 27713368 TI - Mechanism of Allosteric Modulation of the Cys-loop Receptors. AB - The cys-loop receptor family is a major family of neurotransmitter-operated ion channels. They play important roles in fast synaptic transmission, controlling neuronal excitability, and brain function. These receptors are allosteric proteins, in that binding of a neurotransmitter to its binding site remotely controls the channel function. The cys-loop receptors also are subject to allosteric modulation by many pharmaceutical agents and endogenous modulators. By binding to a site of the receptor distinct from the neurotransmitter binding site, allosteric modulators alter the response of the receptors to their agonists. The mechanism of allosteric modulation is traditionally believed to be that allosteric modulators directly change the binding affinity of receptors for their agonists. More recent studies support the notion that these allosteric modulators are very weak agonists or antagonists by themselves. They directly alter channel gating, and thus change the distribution of the receptor across multiple different affinity states, indirectly influencing receptors' sensitivity to agonists. There are two major locations of allosteric modulator binding sites. One is in subunit interfaces of the amino-terminal domain. The other is in the transmembrane domain close to the channel gating machinery. In this review, we also give some examples of well characterized allosteric binding pockets. PMID- 27713369 TI - The Potential Role of Cannabinoids in Modulating Serotonergic Signaling by Their Influence on Tryptophan Metabolism. AB - Phytocannabinoids present in Cannabis plants are well known to exert potent anti inflammatory and immunomodulatory effects. Previously, we have demonstrated that the psychoactive D9-tetrahydrocannabinol (THC) and the non-psychotropic cannabidiol (CBD) modulate mitogen-induced Th1-type immune responses in peripheral blood mononuclear cells (PBMC). The suppressive effect of both cannabinoids on mitogen-induced tryptophan degradation mediated by indoleamine 2,3-dioxygenase (IDO), suggests an additional mechanism by which antidepressive effects of cannabinoids might be linked to the serotonergic system. Here, we will review the role of tryptophan metabolism in the course of cell mediated immune responses and the relevance of cannabinoids in serotonergic signaling. We conclude that in particular the non-psychotropic CBD might be useful for the treatment of mood disorders in patients with inflammatory diseases, since this cannabinoid seems to be safe and its effects on activation-induced tryptophan degradation by CBD were more potent as compared to THC. PMID- 27713371 TI - Overview of Histone Deacetylase Inhibitors in Haematological Malignancies. AB - Histone deacetylase inhibitors (HDACi) can induce hyperacetylation of both histone and non-histone target resulting in epigenetic reprogramming and altered activity, stability and localisation of non-histone proteins to ultimately mediate diverse biological effects on cancer cells and their microenvironment. Clinical trials have demonstrated single agent HDACi to have activity in hematological malignancies, in particular T-cell lymphoma and Hodgkin lymphoma. Combination strategies with standard therapies based on pre-clinical data are being employed with significant success due to their excellent side effect profile. Correlative studies will provide valuable information on the sub-groups of patients more likely to respond or be resistant to HDACi therapy, while long term monitoring for toxicities is also needed. PMID- 27713370 TI - The Role of Cannabinoid Receptors in the Descending Modulation of Pain. AB - The endogenous antinociceptive descending pathway represents a circuitry of the supraspinal central nervous system whose task is to counteract pain. It includes the periaqueductal grey (PAG)-rostral ventromedial medulla (RVM)-dorsal horn (DH) axis, which is the best characterized pain modulation system through which pain is endogenously inhibited. Thus, an alternative rational strategy for silencing pain is the activation of this anatomical substrate. Evidence of the involvement of cannabinoid receptors (CB) in the supraspinal modulation of pain can be found in several studies in which intra-cerebral microinjections of cannabinoid ligands or positive modulators have proved to be analgesic in different pain models, whereas cannabinoid receptor antagonists or antisense nucleotides towards CB1 receptors have facilitated pain. Like opioids, cannabinoids produce centrally mediated analgesia by activating a descending pathway which includes PAG and its projection to downstream RVM neurons, which in turn send inhibitory projections to the dorsal horn of the spinal cord. Indeed, several studies underline a supraspinal regulation of cannabinoids on g-aminobutyric acid (GABA) and glutamate release which inhibit and enhance the antinociceptive descending pathway, respectively. Cannabinoid receptor activation expressed on presynaptic GABAergic terminals reduces the probability of neurotransmitter release thus dis inhibiting the PAG-RVM-dorsal horn antinociceptive pathway. Cannabinoids seem to increase glutamate release (maybe as consequence of GABA decrease) and to require glutamate receptor activation to induce antinociception. The consequent outcome is behavioral analgesia, which is reproduced in several pain conditions, from acute to chronic pain models such as inflammatory and neuropathic pain. Taken together these findings would suggest that supraspinal cannabinoid receptors have broad applications, from pain control to closely related central nervous system diseases such as anxiety and depression. PMID- 27713372 TI - Cannabinoids and Dementia: A Review of Clinical and Preclinical Data. AB - The endocannabinoid system has been shown to be associated with neurodegenerative diseases and dementia. We review the preclinical and clinical data on cannabinoids and four neurodegenerative diseases: Alzheimer's disease (AD), Huntington's disease (HD), Parkinson's disease (PD) and vascular dementia (VD). Numerous studies have demonstrated an involvement of the cannabinoid system in neurotransmission, neuropathology and neurobiology of dementias. In addition, several candidate compounds have demonstrated efficacy in vitro. However, some of the substances produced inconclusive results in vivo. Therefore, only few trials have aimed to replicate the effects seen in animal studies in patients. Indeed, the literature on cannabinoid administration in patients is scarce. While preclinical findings suggest causal treatment strategies involving cannabinoids, clinical trials have only assessed the suitability of cannabinoid receptor agonists, antagonists and cannabidiol for the symptomatic treatment of dementia. Further research is needed, including in vivo models of dementia and human studies. PMID- 27713373 TI - Update on the Genetic Polymorphisms of Drug-Metabolizing Enzymes in Antiepileptic Drug Therapy. AB - Genetic polymorphisms in the genes that encode drug-metabolizing enzymes are implicated in the inter-individual variability in the pharmacokinetics and pharmaco-dynamics of antiepileptic drugs (AEDs). However, the clinical impact of these polymorphisms on AED therapy still remains controversial. The defective alleles of cytochrome P450 (CYP) 2C9 and/or CYP2C19 could affect not only the pharmacokinetics, but also the pharmacodynamics of phenytoin therapy. CYP2C19 deficient genotypes were associated with the higher serum concentration of an active metabolite of clobazam, N-desmethylclobazam, and with the higher clinical efficacy of clobazam therapy than the other CYP2C19 genotypes. The defective alleles of CYP2C9 and/or CYP2C19 were also found to have clinically significant effects on the inter-individual variabilities in the population pharmacokinetics of phenobarbital, valproic acid and zonisamide. EPHX1 polymorphisms may be associated with the pharmacokinetics of carbamazepine and the risk of phenytoin induced congenital malformations. Similarly, the UDP-glucuronosyltransferase 2B7 genotype may affect the pharmacokinetics of lamotrigine. Gluthatione S transferase null genotypes are implicated in an increased risk of hepatotoxicity caused by carbamazepine and valproic acid. This article summarizes the state of research on the effects of mutations of drug-metabolizing enzymes on the pharmacokinetics and pharmacodynamics of AED therapies. Future directions for the dose-adjustment of AED are discussed. PMID- 27713375 TI - Clinical Toxicities of Histone Deacetylase Inhibitors. AB - The HDAC inhibitors are a new family of antineoplastic agents. Since the entry of these agents into our therapeutic armamentarium, there has been increasing interest in their use. Although this family comprises chemical compounds from unrelated chemical classes that have different HDAC isoform specificities, they surprisingly have very similar toxicity profiles. In contrast, the observed toxicity profile is somewhat different from that of traditional cytotoxic chemotherapeutic agents and from other epigenetic agents. While some of the side effects may be familiar to the oncologist, others are less commonly seen. As some patients remain on therapy for a prolonged period of time, the long-term sequelae need to be characterized. In addition, since preclinical models suggest promising activity when used in combination with other antineoplastic agents, combination trials are being pursued. It will thus be important to distinguish the relative toxicity attributed to these agents and be alert to the exacerbation of toxicities observed in single agent studies. Notably, few of the agents in this class have completed phase 2 testing. Consequently, more clinical experience is needed to determine the relative frequency of the observed side effects, and to identify and develop approaches to mitigate potential clinical sequelae. PMID- 27713374 TI - Dendritic Cell Regulation by Cannabinoid-Based Drugs. AB - Cannabinoid pharmacology has made important advances in recent years after the cannabinoid system was discovered. Studies in experimental models and in humans have produced promising results using cannabinoid-based drugs for the treatment of obesity and cancer, as well as neuroinflammatory and chronic inflammatory diseases. Moreover, as we discuss here, additional studies also indicates that these drugs have immunosuppressive and anti-inflammatory properties including modulation of immune cell function. Thus, manipulation of the endocannabinoid system in vivo may provide novel therapeutic strategies against inflammatory disorders. At least two types of cannabinoid receptors, cannabinoid 1 and cannabinoid 2 receptors are expressed on immune cells such as dendritic cells (DC). Dendritic cells are recognized for their critical role in initiating and maintaining immune responses. Therefore, DC are potential targets for cannabinoid mediated modulation. Here, we review the effects of cannabinoids on DC and provide some perspective concerning the therapeutic potential of cannabinoids for the treatment of human diseases involving aberrant inflammatory processes. PMID- 27713378 TI - Role of the G Protein-Coupled Receptor, mGlu1, in Melanoma Development. AB - Melanoma remains one of the cancers for which a decline in morbidity has not been achieved with current scientific and medical advances. Mono-therapies targeting melanoma have been largely ineffective, increasing the need for identification of new drugable targets. Multiple tumor suppressors and oncogenes that impart genetic predisposition to melanoma have been identified and are being studied in an attempt to provide insight on the development of anti-melanoma therapies. Metabotropic Glutamate Receptor I (GRM1) has recently been implicated as a novel oncogene involved in melanomagenesis. GRM1 (mGlu1, protein) belongs to the G protein coupled receptor (GPCR) super family and is normally functional in the central nervous system. Our group showed in a transgenic mouse model system that ectopic expression of Grm1 in melanocytes is sufficient to induce spontaneous melanoma development in vivo. GPCRs are some of the most important therapeutic drug targets discovered to date and they make up a significant proportion of existing therapies. This super family of transmembrane receptors has wide spread expression and interacts with a diverse array of ligands. Diverse physiological responses can be induced by stimulator(s) or suppressor(s) of GPCRs, which contributes to their attractiveness in existing and emerging therapies. GPCR targeting therapies are employed against a variety of human disorders including those of the central nervous system, cardiovascular, metabolic, urogenital and respiratory systems. In the current review, we will discuss how the identification of the oncogenic properties of GRM1 opens up new strategies for the design of potential novel therapies for the treatment of melanoma. PMID- 27713376 TI - Identifying the Ion Channels Responsible for Signaling Gastro-Intestinal Based Pain. AB - We are normally unaware of the complex signalling events which continuously occur within our internal organs. Most of us only become cognisant when sensations of hunger, fullness, urgency or gas arise. However, for patients with organic and functional bowel disorders pain is an unpleasant and often debilitating reminder. Furthermore, chronic pain still represents a large unmet need for clinical treatment. Consequently, chronic pain has a considerable economic impact on health care systems and the afflicted individuals. In order to address this need we must understand how symptoms are generated within the gut, the molecular pathways responsible for generating these signals and how this process changes in disease states. PMID- 27713379 TI - Allosteric Modulation of Muscarinic Acetylcholine Receptors. AB - An allosteric modulator is a ligand that binds to an allosteric site on the receptor and changes receptor conformation to produce increase (positive cooperativity) or decrease (negative cooperativity) in the binding or action of an orthosteric agonist (e.g., acetylcholine). Since the identification of gallamine as the first allosteric modulator of muscarinic receptors in 1976, this unique mode of receptor modulation has been intensively studied by many groups. This review summarizes over 30 years of research on the molecular mechanisms of allosteric interactions of drugs with the receptor and for new allosteric modulators of muscarinic receptors with potential therapeutic use. Identification of positive modulators of acetylcholine binding and function that enhance neurotransmission and the discovery of highly selective allosteric modulators are mile-stones on the way to novel therapeutic agents for the treatment of schizophrenia, Alzheimer's disease and other disorders involving impaired cognitive function. PMID- 27713381 TI - Antiepileptic Drug Discovery and Development: What Have We Learned and Where Are We Going? AB - Current marketed antiepileptic drugs (AEDs) consist of a variety of structural classes with different mechanisms of action. These agents typically have non overlapping efficacy and side-effect profiles presenting multiple treatment options for the patient population. However, approximately 30% of seizure sufferers fail to respond to current therapies often because poorly tolerated side-effects limit adequate dosing. The scope of this review is to summarize selected advances in 2nd and 3rd generation AEDs as well as compounds in development with novel mechanisms of action. PMID- 27713377 TI - Vulnerability Factors for the Psychiatric and Behavioral Effects of Cannabis. AB - Cogent evidence shows that cannabis plays a variable role on behavioral regulation and the pathophysiology of most psychiatric conditions. Accordingly, cannabis has been alternatively shown to exacerbate or ameliorate mental symptoms, depending on its composition and route of consumption, as well as specific individual and contextual characteristics. The vulnerability to the psychological effects of cannabis is influenced by a complex constellation of genetic and environmental factors. In the present article, we will review the current evidence on the pharmacological, individual and situational factors that have been documented to affect the behavioral and psychiatric effects of cannabinoids. PMID- 27713380 TI - Antidepressants and Suicide Risk: A Comprehensive Overview. AB - The annual worldwide suicide rate currently averages approximately 13 per 100,000 individuals per year (0.013% per year), with higher average rates for men than for women in all but a few countries, very low rates in children, and relatively high rates in elderly men. Suicide rates vary markedly between countries, reflecting in part differences in case-identification and reporting procedures. Rates of attempted suicide in the general population average 20-30 times higher than rates of completed suicide, but are probably under-reported. Research on the relationship between pharmacotherapy and suicidal behavior was rare until a decade ago. Most ecological studies and large clinical studies have found that a general reduction in suicide rates is significantly correlated with higher rates of prescribing modern antidepressants. However, ecological, cohort and case control studies and data from brief, randomized, controlled trials in patients with acute affective disorders have found increases, particularly in young patients and particularly for the risk of suicide attempts, as well as increases in suicidal ideation in young patients. whether antidepressants are associated with specific aspects of suicidality (e.g., higher rates of completed suicide, attempted suicide and suicidal ideation) in younger patients with major affective disorders remains a highly controversial question. In light of this gap this paper analyzes research on the relationship between suicidality and antidepressant treatment. PMID- 27713382 TI - Antifungal Properties of Chenopodium ambrosioides Essential Oil Against Candida Species. AB - The essential oil of the aerial part (leaves, flowers and stem) of Chenopodium ambrosioides was obtained by hydrodistillation and its chemical composition analyzed by GC and GC/MS, which permitted the identification of 14 components, representing 98.8% of the total oil. Major components were alpha-terpinene (51.3%), p-cymene (23.4%) and p-mentha-1,8-diene (15.3%). The antifungal properties of this essential oil were investigated in vitro by the well diffusion and broth microdilution methods. The in vitro antifungal activity was concentration dependent and minimum inhibitory concentration values varied from 0.25 to 2 mg/mL. The in vivo antifungal activity was evaluated on an induced vaginal candidiasis rat model. The in vivo activity of the oil on mice vaginal candidiasis was not dose-dependent. Indeed, all the three tested doses; 0.1%, 1% and 10% led to the recovery of mice from the induced infection after 12 days of treatment. The effect of the essential oil on C. albicans ATCC 1663 fatty acid profile was studied. This oil has a relatively important dose-dependent effect on the fatty acids profile. PMID- 27713385 TI - The Art of Managing Conversions between Antiepileptic Drugs: Maximizing Patient Tolerability and Quality of Life. AB - Conversion between anti-epilectic drugs (AEDs) is frequently necessary in epilepsy care, exposing patients to a risk of incurring adverse effects and reduced quality of life. Little practical guidance is available to practitioners to guide conversions between AED monotherapies, or in adding a new adjunctive AED into a polytherapy regimen. This article reviews the impact of adverse effects of AEDs on quality of life in epilepsy patients, then reviews several important patient-related factors such as age, gender, medical and psychiatric co morbidities, and co-medications that must be considered when selecting AEDs and ensuring tolerable and safe AED conversions. Practical strategies for transitional polytherapy AED conversion are then considered in different commonly encountered clinical scenarios in newly diagnosed and refractory epilepsy care, including inadequate seizure control, intolerable adverse effects, or idiosyncratic safety hazards. Successful conversion between AEDs requires regular monitoring for patient-reported adverse effects and appropriately reactive adjustment of AED therapy to maximize patient quality of life. PMID- 27713384 TI - Mechanisms of Broad-Spectrum Antiemetic Efficacy of Cannabinoids against Chemotherapy-Induced Acute and Delayed Vomiting. AB - Chemotherapy-induced nausea and vomiting (CINV) is a complex pathophysiological condition and consists of two phases. The conventional CINV neurotransmitter hypothesis suggests that the immediate phase is mainly due to release of serotonin (5-HT) from the enterochromaffin cells in the gastrointestinal tract (GIT), while the delayed phase is a consequence of release of substance P (SP) in the brainstem. However, more recent findings argue against this simplistic neurotransmitter and anatomical view of CINV. Revision of the hypothesis advocates a more complex, differential and overlapping involvement of several emetic neurotransmitters/modulators (e.g. dopamine, serotonin, substance P, prostaglandins and related arachidonic acid derived metabolites) in both phases of emesis occurring concomitantly in the brainstem and in the GIT enteric nervous system (ENS) [1]. No single antiemetic is currently available to completely prevent both phases of CINV. The standard antiemetic regimens include a 5-HT3 antagonist plus dexamethasone for the prevention of acute emetic phase, combined with an NK1 receptor antagonist (e.g. aprepitant) for the delayed phase. Although NK1 antagonists behave in animals as broad-spectrum antiemetics against different emetogens including cisplatin-induced acute and delayed vomiting, by themselves they are not very effective against CINV in cancer patients. Cannabinoids such as D8-THC also behave as broad-spectrum antiemetics against diverse emetic stimuli as well as being effective against both phases of CINV in animals and patients. Potential side effects may limit the clinical utility of direct-acting cannabinoid agonists which could be avoided by the use of corresponding indirect acting agonists. Cannabinoids (both phyto-derived and synthetic) behave as agonist antiemetics via the activation of cannabinoid CB1 receptors in both the brainstem and the ENS emetic loci. An endocannabinoid antiemetic tone may exist since inverse CB1 agonists (but not the corresponding silent antagonists) cause nausea and vomiting. PMID- 27713383 TI - From Fertilisation to Implantation in Mammalian Pregnancy-Modulation of Early Human Reproduction by the Endocannabinoid System. AB - There is an increasing recognition that the endocannabinoid system is the crucial cytokine-hormone system regulating early human pregnancy. The synchronous development of the fertilized embryo and the endometrium to ensure timely implantation has been shown to be one of the pivotal steps to successful implantation. This development is thought to be regulated by a finely balanced relationship between various components of the endocannabinoid system in the endometrium, the embryo and the Fallopian tube. In addition, this system has also been shown to be involved in the regulation of the development and maturation of the gametes prior to fertilization. In this review, we will examine the evidence from animal and human studies to support the role of the endocannabinoid system in gametogenesis, fertilization, implantation, early pregnancy maintenance, and in immunomodulation of pregnancy. We will discuss the role of the cannabinoid receptors and the enzymes involved in the synthesis and degradation of the key endocannabinoid ligands (e.g., anandamide and 2-arachinoylglycerol) in early reproduction. PMID- 27713386 TI - Tissue Engineering of Cartilage; Can Cannabinoids Help? AB - This review discusses the role of the cannabinoid system in cartilage tissue and endeavors to establish if targeting the cannabinoid system has potential in mesenchymal stem cell based tissue-engineered cartilage repair strategies. The review discusses the potential of cannabinoids to protect against the degradation of cartilage in inflamed arthritic joints and the influence of cannabinoids on the chondrocyte precursors, mesenchymal stem cells (MSCs). We provide experimental evidence to show that activation of the cannabinoid system enhances the survival, migration and chondrogenic differentiation of MSCs, which are three major tenets behind the success of a cell-based tissue-engineered cartilage repair strategy. These findings highlight the potential for cannabinoids to provide a dual function by acting as anti-inflammatory agents as well as regulators of MSC biology in order to enhance tissue engineering strategies aimed at cartilage repair. PMID- 27713387 TI - The Use of Antiepileptic Drugs (AEDs) for the Treatment of Pediatric Aggression and Mood Disorders. AB - Aggressive symptomatology presents across multiple psychiatric, developmental, neurological and behavioral disorders, complicating the diagnosis and treatment of the underlying pathology. Anti-Epileptic Drugs (AEDs) have become an appealing alternative in the treatment of aggression, mood lability and impulsivity in adult and pediatric populations, although few controlled trials have explored their efficacy in treating pediatric populations. This review of the literature synthesizes the available data on ten AEDs - valproate, carbamazepine, oxcarbazepine, phenytoin, lamotrigine, topiramate, levetiracetam, zonisamide, gabapentin and tiagabine - in an attempt to assess evidence for the efficacy of AEDs in the treatment of aggression in pediatric populations. Our review revealed modest evidence that some of the AEDs produced improvement in pediatric aggression, but controlled trials in pediatric bipolar disorder have not been promising. Valproate is the best supported AED for aggression and should be considered as a first line of treatment. When monotherapy is insufficient, combining an AED with either lithium or an atypical anti-psychotic can result in better efficacy. Additionally, our review indicates that medications with predominately GABA-ergic mechanisms of action are not effective in treating aggression, and medications which decrease glutaminergic transmission tended to have more cognitive adverse effects. Agents with multiple mechanisms of action may be more effective.

AB - Type 2 diabetes is a syndrome characterized by relative insulin deficiency, insulin resistance and increased hepatic glucose output. Medications used to treat the disease are designed to correct one or more of these metabolic abnormalities. Current recommendations of the American Diabetes Association (ADA) and European Association for the Study of Diabetes (EASD) include diet and exercise as first-line therapy plus hypoglycemic drugs. Actually there are seven distinct classes of anti-hyperglicemic agents, each of them displaying unique pharmacologic properties. The aim of this review is to describe the pathophysiological basis of their mechanism of action, a necessary step to individualize treatment of diabetic people, taking into proper consideration potential benefits and secondary effects of drugs. PMID- 27713390 TI - Association of STin2 VNTR Polymorphism of Serotonin Transporter Gene with Lifelong Premature Ejaculation: A Case-Control Study in Han Chinese Subjects. AB - BACKGROUND The STin2 VNTR polymorphism has a variable number of tandem repeats in intron 2 of the serotonin transporter gene. We aimed to explore the relationship between STin2 VNTR polymorphism and lifelong premature ejaculation (LPE). MATERIAL AND METHODS We recruited a total of 115 outpatients who complained of ejaculating prematurely and who were diagnosed as LPE, and 101 controls without PE complaint. Allelic variations of STin2 VNTR were genotyped using PCR-based technology. We evaluated the associations between STin2 VNTR allelic and genotypic frequencies and LPE, as well as the intravaginal ejaculation latency time (IELT) of different STin2 VNTR genotypes among LPE patients. RESULTS The patients and controls did not differ significantly in terms of any characteristic except age. A significantly higher frequency of STin2.12/12 genotype was found among LPE patients versus controls (P=0.026). Frequency of patients carrying at least 1 copy of the 10-repeat allele was significantly lower compared to the control group (28.3% vs. 41.8%, OR=0.55; 95%CI=0.31-0.97, P=0.040). In the LPE group, the mean IELT showed significant difference in STin2.12/12 genotype when compared to those with STin2.12/10 and STin2.10/10 genotypes. The mean IELT in10 repeat allele carriers was 50% longer compared to homozygous carriers of the STin2.12 allele. CONCLUSIONS Our results indicate the presence of STin2.10 allele is a protective factor for LPE. Men carrying the higher expression genotype STin2. 12/12 have shorter IELT than 10-repeat allele carriers. PMID- 27713389 TI - Diagnosis and Treatment of Small Bowel Strangulation Due To Congenital Band: Three Cases of Congenital Band in Adults Lacking a History of Trauma or Surgery. AB - BACKGROUND Among the causes of constipation are bands and adhesions that lead to obstructions at different points in the intestinal tract. These can occur as a consequence of healing following surgery or trauma. However, an entity known as congenital band exists where a band is present from birth. Here we report three such cases of adults with symptoms of intestinal obstruction, in whom a congenital band was discovered through exploratory laparoscopy. CASE REPORT All three of these patients presented lacking a history of any abdominal trauma or previous abdominal surgeries, a fact that is often used to exclude an adhesion as a differential. All three recovered quickly and had relief of their symptoms following surgical intervention. CONCLUSIONS Bands and adhesions are common surgical causes of small bowel obstruction, leading to symptoms such as nausea, vomiting, constipation, and obstipation. These bands almost always result from a prior abdominal surgery or from a recent abdominal trauma. The three cases presented here show a far more unusual picture of a band, one that is congenitally present, as there was an absence of such a history. This is significant because clinical suspicion of a band is often very low due to a lack of distinguishing clinical and diagnostic features, and when the past history is negative. PMID- 27713391 TI - Resolution of Hepatic Venous Congestion Following Gradual Occlusion of Middle Hepatic Vein Interposition Graft in Living Donor Liver Transplantation. AB - BACKGROUND The middle hepatic vein (MHV) interposition vessel graft (IVG) is often occluded within a few months after living-donor liver transplantation (LDLT). We aimed to assess the mechanisms of resolving the hepatic venous congestion (HVC) that develops after gradual occlusion of the MHV-IVG. MATERIAL AND METHODS This study comprised two parts. Part I involved an assessment of the process of HVC resolution in the remnant right liver after donation of an extended left liver graft (n=100). Part II involved an evaluation of the timing and patterns of gradual MHV-IVG occlusion and HVC resolution in LDLT recipients (n=100). RESULTS In Part I, the analysis of 1-week dynamic computed tomography (CT) showed pre-existing collaterals in 8, appropriate compensation in 44, and HVC in 48 patients. In Part II, reconstruction of a segment V vein (V5) and a segment VIII vein (V8) was the most common reconstruction type (n=65). The patency rates of MHV-IVG were 90% at 3 months, 65% at 6 months, 37% at 12 months, and 18% at 24 months. The patency rate of V5 was inferior to that of V8. CT imaging analysis indicated that extrinsic compression of IVG, development of intrahepatic collaterals, and IVG shrinkage were the main mechanisms underlying late MHV-IVG occlusion. Moreover, the timing of MHV-IVG occlusion was well correlated with that of neo-collateralization. CONCLUSIONS MHV-IVG reconstruction effectively prevents HVC in LDLT. Although gradual MHV-IVG occlusion is well compensated by neo-collateralization, we believe that the patency of the IVG should be maintained for at least 6 months after LDLT. PMID- 27713392 TI - [Linee guida flebo-linfologiche SIF-SICVE 2016 della Societa Italiana di Flebologia e della Societa Italiana di Chirurgia Vascolare ed Endovascolare]. AB - Phlebology is not a specialty for its own in Italy. Phlebological patients are treated by vascular and general surgeons, dermatologists, phlebologists, angiologists, internists and even general practitioners. Even tough guidelines present a series of recommendations based on evidence-based medicine, guidelines may also be a tool to unify the diagnostic and therapeutic approach in a vast medical field like phlebology. Since vascular surgeons and phlebologists are particularly involved in phlebology-related pathologies the scientific societies of the Italian Society of Phlebology (SIF) and the Italian Society for Vascular and Endovascular Surgery (SICVE) decided to cooperate for the preparation of phlebo-lymphological guidelines. These guidelines comprehend also an important chapter dealing with the lymphology of the lower extremities; phlebological active physicians are often faced with lymphatic pathologies and a good differential diagnosis can be sometimes very helpful. Sclerotherapy and Surgery as the major therapeutical alternatives are extensively analyzed, but also the compression therapy, the medical and physical therapy are presented under the critical view of evidence based analyses. Separate chapters deal with the treatment alternatives for superficial and deep venous thromboses and the recommendations for the treatment of venous ulcers. The current scientific evidences were confronted with the experiences of Italian specialists and the particular practice and reality in Italy. They represent therefore the actual valid positions and recommendations in Italy which shall be updated regularly. PMID- 27713393 TI - Impact of inhibitor of apoptosis proteins on immune modulation and inflammation. AB - The routes leading to programmed cell death are as tightly regulated as those of cellular growth and proliferation, and a finely synchronized balance between the life and death of cells ensures proper organ size and function. Inhibitors of apoptosis (IAPs) proteins were initially characterized by their ability to directly bind and inhibit apoptotic caspases. However, recent studies have clarified that IAPs are much more functionally versatile, modulating a vast range of signaling pathways that have an impact on antimicrobial responses, tumorigenesis, metastasis and cellular migration. A significant contribution of IAPs in tumorigenesis is their inherent function as E3 ubiquitin ligases to modulate cellular signaling downstream of death receptors or certain pattern recognition receptors. In this review, we focus on modulation of the innate and adaptive immune systems, macrophage plasticity and inflammatory responses by IAP family members. We also explore the rationale to target IAPs pharmacologically for the treatment of a number of inflammatory diseases and cancer. PMID- 27713394 TI - Effect of growth hormone and IgG aggregates on dendritic cells activation and T cells polarization. AB - Patients treated with therapeutic biological products (BP) frequently develop anti-drug antibodies (ADA) with potential neutralizing capacities leading to loss of clinical response or serious side effects. BP aggregates have been suggested to promote immunogenicity, thus enhancing ADA production. Dendritic cells (DC) are key effectors in T-cell and B-cell fates, and the subsequent generation of immunogenicity. The objective of this work was to determine if BP aggregates can participate to DC maturation and T-cell activation. We compared aggregates from three different proteins: human growth hormone (hGH), Rituximab, a chimeric anti CD20 antibody and a serum-purified human IgG1. All three proteins underwent a stir stress, generating comparable populations of aggregated particles. Maturation of human monocyte-derived DC (moDC) upon exposure to native BPs or aggregates was evaluated in vitro. Results showed that hGH aggregates induced an increased expression of moDC co-stimulation markers, and augmented levels of IL 6, IL-8, IL-12p40, CCL2, CCL3, CCL4 and CXCL10. Both antibodies aggregates were also able to modify DC phenotype, but cytokine and chemokine productions were seen only with IL-6, IL-8, IL-12p40 and CXCL10. Aggregates-treated moDC enhanced allogenic T-cell proliferation and cytokines production, suggesting Th1 polarization with hGH, and mixed T-cell responses with antibodies aggregates. These results showed that BP aggregates provoked DC maturation, thus driving adaptive T-cell responses and polarization. PMID- 27713395 TI - An interdigit signalling centre instructs coordinate phalanx-joint formation governed by 5'Hoxd-Gli3 antagonism. AB - The number of phalanges and joints are key features of digit 'identity' and are central to limb functionality and evolutionary adaptation. Prior chick work indicated that digit phalanges and their associated joints arise in a different manner than the more sparsely jointed long bones, and their identity is regulated by differential signalling from adjacent interdigits. Currently, there is no genetic evidence for this model, and the molecular mechanisms governing digit joint specification remain poorly understood. Using genetic approaches in mouse, here we show that functional 5'Hoxd-Gli3 antagonism acts indirectly, through Bmp signalling from the interdigital mesenchyme, to regulate specification of joint progenitors, which arise in conjunction with phalangeal precursors at the digit tip. Phalanx number, although co-regulated, can be uncoupled from joint specification. We propose that 5'Hoxd genes and Gli3 are part of an interdigital signalling centre that sets net Bmp signalling levels from different interdigits to coordinately regulate phalanx and joint formation. PMID- 27713396 TI - Motor cortex activity predicts response alternation during sensorimotor decisions. AB - Our actions are constantly guided by decisions based on sensory information. The motor cortex is traditionally viewed as the final output stage in this process, merely executing motor responses based on these decisions. However, it is not clear if, beyond this role, the motor cortex itself impacts response selection. Here, we report activity fluctuations over motor cortex measured using MEG, which are unrelated to choice content and predict responses to a visuomotor task seconds before decisions are made. These fluctuations are strongly influenced by the previous trial's response and predict a tendency to switch between response alternatives for consecutive decisions. This alternation behaviour depends on the size of neural signals still present from the previous response. Our results uncover a response-alternation bias in sensorimotor decision making. Furthermore, they suggest that motor cortex is more than an output stage and instead shapes response selection during sensorimotor decision making. PMID- 27713397 TI - Experimental creation of quantum Zeno subspaces by repeated multi-spin projections in diamond. AB - Repeated observations inhibit the coherent evolution of quantum states through the quantum Zeno effect. In multi-qubit systems this effect provides opportunities to control complex quantum states. Here, we experimentally demonstrate that repeatedly projecting joint observables of multiple spins creates quantum Zeno subspaces and simultaneously suppresses the dephasing caused by a quasi-static environment. We encode up to two logical qubits in these subspaces and show that the enhancement of the dephasing time with increasing number of projections follows a scaling law that is independent of the number of spins involved. These results provide experimental insight into the interplay between frequent multi-spin measurements and slowly varying noise and pave the way for tailoring the dynamics of multi-qubit systems through repeated projections. PMID- 27713398 TI - Mechanisms of aging-related proteinopathies in Caenorhabditis elegans. AB - Aging is the most important risk factor for human neurodegenerative diseases such as Alzheimer's and Parkinson's diseases. Pathologically, these diseases are characterized by the deposition of specific protein aggregates in neurons and glia, representing the impairment of neuronal proteostasis. However, the mechanism by which aging affects the proteostasis system and promotes protein aggregation remains largely unknown. The short lifespan and ample genetic resources of Caenorhabditis elegans (C. elegans) have made this species a favorite model organism for aging research, and the development of proteinopathy models in this organism has helped us to understand how aging processes affect protein aggregation and neurodegeneration. Here, we review the recent literature on proteinopathies in C. elegans models and discuss the insights we have gained into the mechanisms of how aging processes are integrated into the pathogenesis of various neurodegenerative diseases. PMID- 27713399 TI - A novel anti-IL4Ralpha nanoparticle efficiently controls lung inflammation during asthma. AB - Drug resistance and the harmful side effects accompanying the prolonged corticosteroid treatment of chronic pulmonary diseases prompted the development of more specific anti-inflammatory approaches. Several strategies aiming to block IL4Ralpha, the receptor for a key pro-inflammatory pathway, were investigated. However, their efficiency was limited, mostly due to the systemic or subcutaneous route of administrations. In this paper, we examined the ability of an intranasal treatment with biocompatible nanoparticles targeting IL4Ralpha to control lung inflammation in ovalbumin (OVA)-sensitized mice. OVA-sensitized mice were treated with anti-IL4Ralpha-conjugated nanoparticles. The levels of pro-inflammatory cytokines in the lungs and broncho-alveolar lavage fluid (BALF) were determined using a cytokine array assay. The effects of nanoparticle treatment on the activation of lung inflammatory cells and their ability to proliferate and produce cytokines were determined using fluorescence-activated cell sorting (FACS) analysis. Lung inflammation was also monitored using immunohistochemical staining. Treatment with the anti-IL4Ralpha nanoparticles significantly decreased pro-inflammatory cytokine expression and release in BALF and airway lung tissue in mice. The numbers of lung tissue lymphocytes, neutrophils and eosinophils were also decreased. Interestingly, anti-IL4Ralpha nanoparticles deactivated CD4 and CD8 T cells in lung tissue and inhibited their ability to produce pro inflammatory cytokines to a significantly lower level than the treatment with free anti-IL4Ralpha. Moreover, they induced a sustained low level of lung inflammation for 1 week following the last instillation compared with the treatment with free anti-IL4Ralpha antibodies. Together, this data suggested that the enhanced tissue penetrability and sustainability of these nanoparticles improved the strength and durability of the immunosuppressive effects of anti IL4Ralpha. PMID- 27713400 TI - Non-enzymatic pyridine ring formation in the biosynthesis of the rubrolone tropolone alkaloids. AB - The pyridine ring is a potent pharmacophore in alkaloid natural products. Nonetheless, its biosynthetic pathways are poorly understood. Rubrolones A and B are tropolone alkaloid natural products possessing a unique tetra-substituted pyridine moiety. Here, we report the gene cluster and propose a biosynthetic pathway for rubrolones, identifying a key intermediate that accumulates upon inactivation of sugar biosynthetic genes. Critically, this intermediate was converted to the aglycones of rubrolones by non-enzymatic condensation and cyclization with either ammonia or anthranilic acid to generate the respective pyridine rings. We propose that this non-enzymatic reaction occurs via hydrolysis of the key intermediate, which possesses a 1,5-dione moiety as an amine acceptor capable of cyclization. This study suggests that 1,5-dione moieties may represent a general strategy for pyridine ring biosynthesis, and more broadly highlights the utility of non-enzymatic diversification for exploring and expanding natural product chemical space. PMID- 27713401 TI - Synergism between RIZ1 gene therapy and paclitaxel in SiHa cervical cancer cells. AB - RIZ1 is a tumor suppressor gene. The purpose of the present study was to investigate the inhibitory effect of RIZ1 gene therapy on the growth of SiHa cervical cancer cells and its synergism with paclitaxel. The expression levels of RIZ1 were examined by real-time PCR and western blotting before and after transfection of RIZ1. The effects of paclitaxel or pcDNA3.1(+)-RIZ1 alone or in combination, on the proliferation of SiHa cells were evaluated by MTT method. The inhibitory effect on the proliferation of SiHa cells was more significant in the pcDNA3.1(+)-RIZ1 combined with paclitaxel group than in the pcDNA3.1(+)-RIZ1 or paclitaxel groups (P<0.05). The expression level of RIZ1 in SiHa cells increased after treatment with paclitaxel, which indicated a synergism between them. RIZ1 gene therapy combined with paclitaxel showed stronger cell inhibition than paclitaxel alone, which indicated a synergism between them. PMID- 27713402 TI - Structural characterization of antibiotic self-immunity tRNA synthetase in plant tumour biocontrol agent. AB - Antibiotic-producing microbes evolved self-resistance mechanisms to avoid suicide. The biocontrol Agrobacterium radiobacter K84 secretes the Trojan Horse antibiotic agrocin 84 that is selectively transported into the plant pathogen A. tumefaciens and processed into the toxin TM84. We previously showed that TM84 employs a unique tRNA-dependent mechanism to inhibit leucyl-tRNA synthetase (LeuRS), while the TM84-producer prevents self-poisoning by expressing a resistant LeuRS AgnB2. We now identify a mechanism by which the antibiotic producing microbe resists its own toxin. Using a combination of structural, biochemical and biophysical approaches, we show that AgnB2 evolved structural changes so as to resist the antibiotic by eliminating the tRNA-dependence of TM84 binding. Mutagenesis of key resistance determinants results in mutants adopting an antibiotic-sensitive phenotype. This study illuminates the evolution of resistance in self-immunity genes and provides mechanistic insights into a fascinating tRNA-dependent antibiotic with applications for the development of anti-infectives and the prevention of biocontrol emasculation. PMID- 27713403 TI - Scaled laboratory experiments explain the kink behaviour of the Crab Nebula jet. AB - The remarkable discovery by the Chandra X-ray observatory that the Crab nebula's jet periodically changes direction provides a challenge to our understanding of astrophysical jet dynamics. It has been suggested that this phenomenon may be the consequence of magnetic fields and magnetohydrodynamic instabilities, but experimental demonstration in a controlled laboratory environment has remained elusive. Here we report experiments that use high-power lasers to create a plasma jet that can be directly compared with the Crab jet through well-defined physical scaling laws. The jet generates its own embedded toroidal magnetic fields; as it moves, plasma instabilities result in multiple deflections of the propagation direction, mimicking the kink behaviour of the Crab jet. The experiment is modelled with three-dimensional numerical simulations that show exactly how the instability develops and results in changes of direction of the jet. PMID- 27713404 TI - Multi-omics integration accurately predicts cellular state in unexplored conditions for Escherichia coli. AB - A significant obstacle in training predictive cell models is the lack of integrated data sources. We develop semi-supervised normalization pipelines and perform experimental characterization (growth, transcriptional, proteome) to create Ecomics, a consistent, quality-controlled multi-omics compendium for Escherichia coli with cohesive meta-data information. We then use this resource to train a multi-scale model that integrates four omics layers to predict genome wide concentrations and growth dynamics. The genetic and environmental ontology reconstructed from the omics data is substantially different and complementary to the genetic and chemical ontologies. The integration of different layers confers an incremental increase in the prediction performance, as does the information about the known gene regulatory and protein-protein interactions. The predictive performance of the model ranges from 0.54 to 0.87 for the various omics layers, which far exceeds various baselines. This work provides an integrative framework of omics-driven predictive modelling that is broadly applicable to guide biological discovery. PMID- 27713406 TI - Formation of metastable phases by spinodal decomposition. AB - Metastable phases may be spontaneously formed from other metastable phases through nucleation. Here we demonstrate the spontaneous formation of a metastable phase from an unstable equilibrium by spinodal decomposition, which leads to a transient coexistence of stable and metastable phases. This phenomenon is generic within the recently introduced scenario of the landscape-inversion phase transitions, which we experimentally realize as a structural transition in a colloidal crystal. This transition exhibits a rich repertoire of new phase ordering phenomena, including the coexistence of two equilibrium phases connected by two physically different interfaces. In addition, this scenario enables the control of sizes and lifetimes of metastable domains. Our findings open a new setting that broadens the fundamental understanding of phase-ordering kinetics, and yield new prospects of applications in materials science. PMID- 27713405 TI - Molecular analysis of aggressive renal cell carcinoma with unclassified histology reveals distinct subsets. AB - Renal cell carcinomas with unclassified histology (uRCC) constitute a significant portion of aggressive non-clear cell renal cell carcinomas that have no standard therapy. The oncogenic drivers in these tumours are unknown. Here we perform a molecular analysis of 62 high-grade primary uRCC, incorporating targeted cancer gene sequencing, RNA sequencing, single-nucleotide polymorphism array, fluorescence in situ hybridization, immunohistochemistry and cell-based assays. We identify recurrent somatic mutations in 29 genes, including NF2 (18%), SETD2 (18%), BAP1 (13%), KMT2C (10%) and MTOR (8%). Integrated analysis reveals a subset of 26% uRCC characterized by NF2 loss, dysregulated Hippo-YAP pathway and worse survival, whereas 21% uRCC with mutations of MTOR, TSC1, TSC2 or PTEN and hyperactive mTORC1 signalling are associated with better clinical outcome. FH deficiency (6%), chromatin/DNA damage regulator mutations (21%) and ALK translocation (2%) distinguish additional cases. Altogether, this study reveals distinct molecular subsets for 76% of our uRCC cohort, which could have diagnostic and therapeutic implications. PMID- 27713407 TI - Striatal prediction errors support dynamic control of declarative memory decisions. AB - Adaptive memory requires context-dependent control over how information is retrieved, evaluated and used to guide action, yet the signals that drive adjustments to memory decisions remain unknown. Here we show that prediction errors (PEs) coded by the striatum support control over memory decisions. Human participants completed a recognition memory test that incorporated biased feedback to influence participants' recognition criterion. Using model-based fMRI, we find that PEs-the deviation between the outcome and expected value of a memory decision-correlate with striatal activity and predict individuals' final criterion. Importantly, the striatal PEs are scaled relative to memory strength rather than the expected trial outcome. Follow-up experiments show that the learned recognition criterion transfers to free recall, and targeting biased feedback to experimentally manipulate the magnitude of PEs influences criterion consistent with PEs scaled relative to memory strength. This provides convergent evidence that declarative memory decisions can be regulated via striatally mediated reinforcement learning signals. PMID- 27713408 TI - Mutually exclusive sense-antisense transcription at FLC facilitates environmentally induced gene repression. AB - Antisense transcription through genic regions is pervasive in most genomes; however, its functional significance is still unclear. We are studying the role of antisense transcripts (COOLAIR) in the cold-induced, epigenetic silencing of Arabidopsis FLOWERING LOCUS C (FLC), a regulator of the transition to reproduction. Here we use single-molecule RNA FISH to address the mechanistic relationship of FLC and COOLAIR transcription at the cellular level. We demonstrate that while sense and antisense transcripts can co-occur in the same cell they are mutually exclusive at individual loci. Cold strongly upregulates COOLAIR transcription in an increased number of cells and through the mutually exclusive relationship facilitates shutdown of sense FLC transcription in cis. COOLAIR transcripts form dense clouds at each locus, acting to influence FLC transcription through changed H3K36me3 dynamics. These results may have general implications for other loci showing both sense and antisense transcription. PMID- 27713409 TI - Evolutionary interplay between sister cytochrome P450 genes shapes plasticity in plant metabolism. AB - Expansion of the cytochrome P450 gene family is often proposed to have a critical role in the evolution of metabolic complexity, in particular in microorganisms, insects and plants. However, the molecular mechanisms underlying the evolution of this complexity are poorly understood. Here we describe the evolutionary history of a plant P450 retrogene, which emerged and underwent fixation in the common ancestor of Brassicales, before undergoing tandem duplication in the ancestor of Brassicaceae. Duplication leads first to gain of dual functions in one of the copies. Both sister genes are retained through subsequent speciation but eventually return to a single copy in two of three diverging lineages. In the lineage in which both copies are maintained, the ancestral functions are split between paralogs and a novel function arises in the copy under relaxed selection. Our work illustrates how retrotransposition and gene duplication can favour the emergence of novel metabolic functions. PMID- 27713410 TI - Abundant DNA 6mA methylation during early embryogenesis of zebrafish and pig. AB - DNA N6-methyldeoxyadenosine (6mA) is a well-known prokaryotic DNA modification that has been shown to exist and play epigenetic roles in eukaryotic DNA. Here we report that 6mA accumulates up to ~0.1-0.2% of total deoxyadenosine during early embryogenesis of vertebrates, but diminishes to the background level with the progression of the embryo development. During this process a large fraction of 6mAs locate in repetitive regions of the genome. PMID- 27713411 TI - Electronic control of H+ current in a bioprotonic device with Gramicidin A and Alamethicin. AB - In biological systems, intercellular communication is mediated by membrane proteins and ion channels that regulate traffic of ions and small molecules across cell membranes. A bioelectronic device with ion channels that control ionic flow across a supported lipid bilayer (SLB) should therefore be ideal for interfacing with biological systems. Here, we demonstrate a biotic-abiotic bioprotonic device with Pd contacts that regulates proton (H+) flow across an SLB incorporating the ion channels Gramicidin A (gA) and Alamethicin (ALM). We model the device characteristics using the Goldman-Hodgkin-Katz (GHK) solution to the Nernst-Planck equation for transport across the membrane. We derive the permeability for an SLB integrating gA and ALM and demonstrate pH control as a function of applied voltage and membrane permeability. This work opens the door to integrating more complex H+ channels at the Pd contact interface to produce responsive biotic-abiotic devices with increased functionality. PMID- 27713412 TI - Nanoscale probing of electron-regulated structural transitions in silk proteins by near-field IR imaging and nano-spectroscopy. AB - Silk protein fibres produced by silkworms and spiders are renowned for their unparalleled mechanical strength and extensibility arising from their high-beta sheet crystal contents as natural materials. Investigation of beta-sheet-oriented conformational transitions in silk proteins at the nanoscale remains a challenge using conventional imaging techniques given their limitations in chemical sensitivity or limited spatial resolution. Here, we report on electron-regulated nanoscale polymorphic transitions in silk proteins revealed by near-field infrared imaging and nano-spectroscopy at resolutions approaching the molecular level. The ability to locally probe nanoscale protein structural transitions combined with nanometre-precision electron-beam lithography offers us the capability to finely control the structure of silk proteins in two and three dimensions. Our work paves the way for unlocking essential nanoscopic protein structures and critical conditions for electron-induced conformational transitions, offering new rules to design protein-based nanoarchitectures. PMID- 27713413 TI - Thermally-nucleated self-assembly of water and alcohol into stable structures at hydrophobic interfaces. AB - At the interface with solids, the mobility of liquid molecules tends to be reduced compared with bulk, often resulting in increased local order due to interactions with the surface of the solid. At room temperature, liquids such as water and methanol can form solvation structures, but the molecules remain highly mobile, thus preventing the formation of long-lived supramolecular assemblies. Here we show that mixtures of water with methanol can form a novel type of interfaces with hydrophobic solids. Combining in situ atomic force microscopy and multiscale molecular dynamics simulations, we identify solid-like two-dimensional interfacial structures that nucleate thermally, and are held together by an extended network of hydrogen bonds. On graphite, nucleation occurs above ~35 degrees C, resulting in robust, multilayered nanoscopic patterns. Our findings could have an impact on many fields where water-alcohol mixtures play an important role such as fuel cells, chemical synthesis, self-assembly, catalysis and surface treatments. PMID- 27713414 TI - N-type organic electrochemical transistors with stability in water. AB - Organic electrochemical transistors (OECTs) are receiving significant attention due to their ability to efficiently transduce biological signals. A major limitation of this technology is that only p-type materials have been reported, which precludes the development of complementary circuits, and limits sensor technologies. Here, we report the first ever n-type OECT, with relatively balanced ambipolar charge transport characteristics based on a polymer that supports both hole and electron transport along its backbone when doped through an aqueous electrolyte and in the presence of oxygen. This new semiconducting polymer is designed specifically to facilitate ion transport and promote electrochemical doping. Stability measurements in water show no degradation when tested for 2 h under continuous cycling. This demonstration opens the possibility to develop complementary circuits based on OECTs and to improve the sophistication of bioelectronic devices. PMID- 27713416 TI - Single-shot observation of optical rogue waves in integrable turbulence using time microscopy. AB - Optical fibres are favourable tabletop laboratories to investigate both coherent and incoherent nonlinear waves. In particular, exact solutions of the one dimensional nonlinear Schrodinger equation such as fundamental solitons or solitons on finite background can be generated by launching periodic, specifically designed coherent waves in optical fibres. It is an open fundamental question to know whether these coherent structures can emerge from the nonlinear propagation of random waves. However the typical sub-picosecond timescale prevented-up to now-time-resolved observations of the awaited dynamics. Here, we report temporal 'snapshots' of random light using a specially designed 'time microscope'. Ultrafast structures having peak powers much larger than the average optical power are generated from the propagation of partially coherent waves in optical fibre and are recorded with 250 femtoseconds resolution. Our experiment demonstrates the central role played by 'breather-like' structures such as the Peregrine soliton in the emergence of heavy-tailed statistics in integrable turbulence. PMID- 27713417 TI - Social learning strategies modify the effect of network structure on group performance. AB - The structure of communication networks is an important determinant of the capacity of teams, organizations and societies to solve policy, business and science problems. Yet, previous studies reached contradictory results about the relationship between network structure and performance, finding support for the superiority of both well-connected efficient and poorly connected inefficient network structures. Here we argue that understanding how communication networks affect group performance requires taking into consideration the social learning strategies of individual team members. We show that efficient networks outperform inefficient networks when individuals rely on conformity by copying the most frequent solution among their contacts. However, inefficient networks are superior when individuals follow the best member by copying the group member with the highest payoff. In addition, groups relying on conformity based on a small sample of others excel at complex tasks, while groups following the best member achieve greatest performance for simple tasks. Our findings reconcile contradictory results in the literature and have broad implications for the study of social learning across disciplines. PMID- 27713415 TI - Endoglin integrates BMP and Wnt signalling to induce haematopoiesis through JDP2. AB - Mechanisms of haematopoietic and cardiac patterning remain poorly understood. Here we show that the BMP and Wnt signalling pathways are integrated in an endoglin (Eng)-dependent manner in cardiac and haematopoietic lineage specification. Eng is expressed in early mesoderm and marks both haematopoietic and cardiac progenitors. In the absence of Eng, yolk sacs inappropriately express the cardiac marker, Nkx2.5. Conversely, high levels of Eng in vitro and in vivo increase haematopoiesis and inhibit cardiogenesis. Levels of Eng determine the activation of both BMP and Wnt pathways, which are integrated downstream of Eng by phosphorylation of Smad1 by Gsk3. By interrogating Eng-dependent Wnt-mediated transcriptional changes, we identify Jdp2 as a key Eng-dependent Wnt target, sufficient to establish haematopoietic fate in early mesoderm when BMP and Wnt crosstalk is disturbed. These studies provide mechanistic insight into the integration of BMP and Wnt signalling in the establishment of haematopoietic and cardiac progenitors during embryogenesis. PMID- 27713418 TI - Papillary thyroid carcinoma with nodular fasciitis-like stroma and beta-catenin mutations should be renamed papillary thyroid carcinoma with desmoid-type fibromatosis. AB - Various histological variants of papillary thyroid carcinoma have been reported, some with clinical implications, some with peculiar, sometimes misleading morphologies. One of these rare and poorly characterized variants is papillary thyroid carcinoma with nodular fasciitis-like stroma, of which fewer than 30 cases have been documented, mostly as isolated reports. It is a dual tumor comprising a malignant epithelial proliferation that harbors typical features of conventional papillary thyroid carcinoma, admixed with a prominent mesenchymal proliferation resembling nodular fasciitis or fibromatosis. Thus, the terms papillary thyroid carcinoma with nodular fasciitis-like stroma and papillary thyroid carcinoma with fibromatosis-like stroma are used interchangeably; however, the former term suggests a self-limited and regressing disease, whereas the latter one suggests a recurrent and potentially aggressive one. Better genetic and ultrastructural characterization could lead to more appropriate terminology and management. We performed detailed clinicopathological and molecular analyses of two cases of PTC with prominent mesenchymal proliferation that developed in the thyroid gland of two male patients aged 34 and 48. In both cases, the epithelial component harbored a heterozygous somatic activating BRAF mutation (p.V600E). Also, in both cases, the mesenchymal component showed typical aberrant nuclear and cytoplasmic immunoreactivity for beta-catenin and harbored a heterozygous somatic activating mutation in the corresponding CTNNB1 gene (p.S45P). This mutation has never been reported in thyroid stroma; in other tissues, it is typical of desmoid-type fibromatosis rather than nodular fasciitis like stroma. We therefore propose that in cases of papillary thyroid carcinoma with a prominent mesenchymal component, mutations in CTNNB1 should be sought; when they are present, the term 'papillary thyroid carcinoma with desmoid-type fibromatosis' should be used. As the mesenchymal component of these tumors is not expected to concentrate radioactive iodine, special considerations apply to clinical evaluation and follow-up, which should be brought to the attention of the treating specialist. PMID- 27713420 TI - Colorectal carcinomas with submucosal invasion (pT1): analysis of histopathological and molecular factors predicting lymph node metastasis. AB - Submucosally invasive colorectal carcinoma (pT1) has the potential to be cured by local excision. In US surgical intervention is reserved for tumors with high grade morphology, lymphvascular invasion, and close/positive margin. In other countries, particularly Japan, surgical therapy is also recommended for mucinous tumors, tumors with >1000 MUm of submucosal invasion, and those with high tumor budding. These histological features have not been well evaluated in a western cohort of pT1 carcinomas. In a cohort of 116 surgically resected pT1 colorectal carcinomas, high tumor budding (P<0.001), lymphatic invasion (P=0.003), depth of submucosal invasion >1000 MUm (P=0.04), and high-grade morphology (P=0.04) were significantly associated with lymph node metastasis on univariate analysis. Mucinous differentiation, tumor location, tumor growth pattern, and size of invasive component were not significant. On multivariate analysis, only high tumor budding was associated with lymph node metastasis with an odds ratio of 4.3 (P=0.004). A subset of 48 tumors (22 node-positive and 26 node-negative) was analyzed for mutations in 50 oncogenes and tumor suppressors. No statistically significant molecular alterations in these 50 genes were associated with lymph node status. However, lymphatic invasion was associated with BRAF mutations (P=0.01). Furthermore, high tumor budding was associated with mutations in TP53 (P=0.03) and inversely associated with mutations in the mTOR pathway (PIK3CA and AKT, P=0.02). In conclusion, this study demonstrates the importance of identifying high tumor budding in pT1 carcinomas when considering additional surgical resection. Molecular alterations associated with adverse histological features are identified. PMID- 27713419 TI - Genetic analysis of microglandular adenosis and acinic cell carcinomas of the breast provides evidence for the existence of a low-grade triple-negative breast neoplasia family. AB - Acinic cell carcinoma is an indolent form of invasive breast cancer, whereas microglandular adenosis has been shown to be a neoplastic proliferation. Both entities display a triple-negative phenotype, and may give rise to and display somatic genomic alterations typical of high-grade triple-negative breast cancers. Here we report on a comparison of previously published data on eight carcinoma associated microglandular adenosis and eight acinic cell carcinomas subjected to targeted massively parallel sequencing targeting all exons of 236 genes recurrently mutated in breast cancer and/or DNA repair-related. Somatic mutations, insertions/ deletions, and copy number alterations were detected using state-of-the-art bioinformatic algorithms. All cases were of triple-negative phenotype. A median of 4.5 (1-13) and 4.0 (1-7) non-synonymous somatic mutations per carcinoma-associated microglandular adenosis and acinic cell carcinoma were identified, respectively. TP53 was the sole highly recurrently mutated gene (75% in microglandular adenosis versus 88% in acinic cell carcinomas), and TP53 mutations were consistently coupled with loss of heterozygosity of the wild-type allele. Additional somatic mutations shared by both groups included those in BRCA1, PIK3CA, and INPP4B. Recurrent (n=2) somatic mutations restricted to microglandular adenosis or acinic cell carcinomas included those affecting PTEN and MED12 or ERBB4, respectively. No significant differences in the repertoire of somatic mutations were detected between microglandular adenosis and acinic cell carcinomas, and between this group of lesions and 77 triple-negative carcinomas from The Cancer Genome Atlas. Microglandular adenosis and acinic cell carcinomas, however, were genetically distinct from estrogen receptor-positive and/or HER2 positive breast cancers from The Cancer Genome Atlas. Our findings support the contention that microglandular adenosis and acinic cell carcinoma are part of the same spectrum of lesions harboring frequent TP53 somatic mutations, and likely represent low-grade forms of triple-negative disease with no/minimal metastatic potential, of which a subset has the potential to progress to high-grade triple negative breast cancer. PMID- 27713422 TI - Diagnosis of T1 colorectal cancer in pedunculated polyps in daily clinical practice: a multicenter study. AB - T1 colorectal cancer can be mimicked by pseudo-invasion in pedunculated polyps. British guidelines are currently one of the few which recommend diagnostic confirmation of T1 colorectal cancer by a second pathologist. The aim of this study was to provide insights into the accuracy of histological diagnosis of pedunculated T1 colorectal cancer in daily clinical practice. A sample of 128 cases diagnosed as pedunculated T1 colorectal cancer between 2000 and 2014 from 10 Dutch hospitals was selected for histological review. Firstly, two Dutch expert gastrointestinal pathologists reviewed all hematoxylin-eosin stained slides. In 20 cases the diagnosis T1 colorectal cancer was not confirmed (20/128; 16%). The discordant cases were subsequently discussed with a third Dutch gastrointestinal pathologist and a consensus diagnosis was agreed. The revised diagnoses were pseudo-invasion in 10 cases (10/128; 8%), high-grade dysplasia in 4 cases (4/128; 3%), and equivocal in 6 cases (6/128; 5%). To further validate the consensus diagnosis, the discordant cases were reviewed by an independent expert pathologist from the United Kingdom. A total of 39 cases were reviewed blindly including the 20 cases with a revised diagnosis and 19 control cases where the Dutch expert panel agreed with the original reporting pathologists diagnosis. In 19 of the 20 cases with a revised diagnosis the British pathologist agreed that T1 colorectal cancer could not be confirmed. Additionally, amongst the 19 control cases the British pathologist was unable to confirm T1 colorectal cancer in a further 4 cases and was equivocal in 3 cases. In conclusion, both generalist and expert pathologists experience diagnostic difficulty distinguishing pseudo-invasion and high-grade dysplasia from T1 colorectal cancer. In order to prevent overtreatment, review of the histology of pedunculated T1 colorectal cancers by a second pathologist should be considered with discussion of these cases at a multidisciplinary meeting. PMID- 27713421 TI - Upper tract urothelial carcinomas: frequency of association with mismatch repair protein loss and lynch syndrome. AB - Increased risk for upper tract urothelial carcinoma is described in patients with Lynch syndrome, caused by germline mutations in mismatch repair genes. We aimed to identify the frequency of mismatch repair protein loss in upper tract urothelial carcinoma and its potential for identifying an association with Lynch syndrome. We queried our database to identify upper tract urothelial carcinomas. Patients were cross-referenced for history of colorectal carcinoma or other common Lynch syndrome-associated neoplasms to enrich for potential Lynch syndrome cases. Tumor histopathologic characteristics were reviewed and each case was analyzed for loss of mismatch repair proteins, MLH1, MSH2, MSH6, and PMS2, by immunohistochemistry. Of 444 patients with upper tract urothelial carcinoma, a subset of 215 (encompassing 30 with upper tract urothelial carcinoma and another common Lynch syndrome-associated neoplasm) was analyzed for loss of mismatch repair protein expression. Of 30 patients with Lynch syndrome-associated neoplasms, six had documented Lynch syndrome, including two with Muir-Torre syndrome. Mismatch repair protein loss was identified in 7% of total upper tract urothelial carcinomas and 30% of patients with Lynch syndrome-associated neoplasms (including all patients with Lynch syndrome/Muir-Torre syndrome). Of patients without history of Lynch syndrome-associated neoplasms, 5 of 184 (2.7%) had loss of mismatch repair protein expression. Twelve cases with mismatch repair protein loss demonstrated loss of MSH2 and MSH6, and 2 had isolated loss of MSH6. MLH1 and PMS2 expression were consistently retained. Although increased intratumoral lymphocytes, inverted growth, pushing tumor-stromal interface, and lack of nuclear pleomorphism were more commonly seen in cases with mismatch repair protein loss, only intratumoral lymphocytes and presence of pushing borders were statistically significant. MLH1 and PMS2 testing appear to have little utility in upper tract urothelial carcinoma; however, mismatch repair protein loss of MSH2 and/or MSH6 by immunohistochemistry seems relatively sensitive and specific for identifying patients with potential Lynch syndrome. PMID- 27713423 TI - Downregulation of acetyl-CoA synthetase 2 is a metabolic hallmark of tumor progression and aggressiveness in colorectal carcinoma. AB - Acetyl-CoA synthetase-2 is an emerging key enzyme for cancer metabolism, which supplies acetyl-CoA for tumor cells by capturing acetate as a carbon source under stressed conditions. However, implications of acetyl-CoA synthetase-2 in colorectal carcinoma may differ from other malignancies, because normal colonocytes use short-chain fatty acids as an energy source, which are supplied by fermentation of the intestinal flora. Here we analyzed acetyl-CoA synthetase-2 mRNA expression by reverse-transcription quantitative PCR in paired normal mucosa and tumor tissues of 12 colorectal carcinomas, and subsequently evaluated acetyl CoA synthetase-2 protein expression by immunohistochemistry in 157 premalignant colorectal lesions, including 60 conventional adenomas and 97 serrated polyps, 1,106 surgically resected primary colorectal carcinomas, and 23 metastatic colorectal carcinomas in the liver. In reverse-transcription quantitative PCR analysis, acetyl-CoA synthetase-2 mRNA expression was significantly decreased in tumor tissues compared with corresponding normal mucosa tissues. In acetyl-CoA synthetase-2 immunohistochemistry analysis, all 157 colorectal polyps showed moderate-to-strong expression of acetyl-CoA synthetase-2. However, cytoplasmic acetyl-CoA synthetase-2 expression was downregulated (acetyl-CoA synthetase-2 low expression) in 771 (69.7%) of 1,106 colorectal carcinomas and 21 (91.3%) of 23 metastatic lesions. The colorectal carcinomas with acetyl-CoA synthetase-2-low expression were significantly associated with advanced TNM stage, poor differentiation, and frequent tumor budding. Regarding the molecular aspect, acetyl-CoA synthetase-2-low expression exhibited a tendency of frequent KRT7 expression and decreased KRT20 and CDX2 expression. In survival analysis, acetyl CoA synthetase-2-low expression was an independent prognostic factor for poor 5 year progression-free survival (hazard ratio, 1.39; 95% confidence interval, 1.08 1.79; P=0.01). In conclusion, these findings suggest that downregulation of acetyl-CoA synthetase-2 expression is a metabolic hallmark of tumor progression and aggressive behavior in colorectal carcinoma. PMID- 27713424 TI - 5-Hydroxymethylcytosine is an independent predictor of survival in malignant melanoma. AB - Outcomes for melanoma patients vary within cancer stage. Prognostic biomarkers are potential adjuncts to provide more precise prognostic information. Simple, low-cost biomarker assays, such as those based on immunohistochemistry, have strong translational potential. 5-hydroxymethylcytosine (5 hmC) shows prognostic potential in melanoma but prior studies were small. We, therefore, analysed 5 hmC in a retrospective cohort to provide external validation of its prognostic value. Two hundred primary melanomas were evaluated for 5 hmC expression using immunohistochemistry. The primary objective was to assess the effect on overall survival while controlling for important confounders. Univariable and multivariable analyses were performed. REMARK guidelines were followed. The 5 hmC immunohistochemistry scoring showed very strong inter-observer agreement (ICC 0.88) and expression was significantly related to age, site, Breslow thickness, ulceration, mitotic rate, and stage. Kaplan-Meier analysis showed 5 hmC was associated with metastasis-free, melanoma-specific, and overall survival, P<0.0001 for each. In univariable Cox proportional hazards models, 5 hmC hazard ratios were significant and remained so in a multivariable model. A two-step cox model was created using stage and 5 hmC, as stage is the gold standard for clinical practice. The addition of 5 hmC produced significant improvement in the model and 5 hmC and stage were independent significant predictors. This is the largest study of the prognostic value of 5 hmC immunohistochemistry in melanoma. The 5 hmC scoring was easily and reproducibly performed and it was an independent predictor of metastasis-free survival, melanoma-specific survival, and overall survival. This work supports further development of 5 hmC as a prognostic biomarker and suggests that it could add more precision to American Joint Committee on Cancer staging. PMID- 27713426 TI - Orbital disproportionation of electronic density is a universal feature of alkali doped fullerides. AB - Alkali-doped fullerides show a wide range of electronic phases in function of alkali atoms and the degree of doping. Although the presence of strong electron correlations is well established, recent investigations also give evidence for dynamical Jahn-Teller instability in the insulating and the metallic trivalent fullerides. In this work, to reveal the interplay of these interactions in fullerides with even electrons, we address the electronic phase of tetravalent fulleride with accurate many-body calculations within a realistic electronic model including all basic interactions extracted from first principles. We find that the Jahn-Teller instability is always realized in these materials too. In sharp contrast to the correlated metals, tetravalent system displays uncorrelated band-insulating state despite similar interactions present in both fullerides. Our results show that the Jahn-Teller instability and the accompanying orbital disproportionation of electronic density in the degenerate lowest unoccupied molecular orbital band is a universal feature of fullerides. PMID- 27713425 TI - Bimodal antagonism of PKA signalling by ARHGAP36. AB - Protein kinase A is a key mediator of cAMP signalling downstream of G-protein coupled receptors, a signalling pathway conserved in all eukaryotes. cAMP binding to the regulatory subunits (PKAR) relieves their inhibition of the catalytic subunits (PKAC). Here we report that ARHGAP36 combines two distinct inhibitory mechanisms to antagonise PKA signalling. First, it blocks PKAC activity via a pseudosubstrate motif, akin to the mechanism employed by the protein kinase inhibitor proteins. Second, it targets PKAC for rapid ubiquitin-mediated lysosomal degradation, a pathway usually reserved for transmembrane receptors. ARHGAP36 thus dampens the sensitivity of cells to cAMP. We show that PKA inhibition by ARHGAP36 promotes derepression of the Hedgehog signalling pathway, thereby providing a simple rationale for the upregulation of ARHGAP36 in medulloblastoma. Our work reveals a new layer of PKA regulation that may play an important role in development and disease. PMID- 27713431 TI - Antibiotic resistance: Correct dosage. PMID- 27713428 TI - Sensory feedback synchronizes motor and sensory neuronal networks in the neonatal rat spinal cord. AB - Early stages of sensorimotor system development in mammals are characterized by the occurrence of spontaneous movements. Whether and how these movements support correlated activity in developing sensorimotor spinal cord circuits remains unknown. Here we show highly correlated activity in sensory and motor zones in the spinal cord of neonatal rats in vivo. Both during twitches and complex movements, movement-generating bursts in motor zones are followed by bursts in sensory zones. Deafferentation does not affect activity in motor zones and movements, but profoundly suppresses activity bursts in sensory laminae and results in sensorimotor uncoupling, implying a primary role of sensory feedback in sensorimotor synchronization. This is further supported by largely dissociated activity in sensory and motor zones observed in the isolated spinal cord in vitro. Thus, sensory feedback resulting from spontaneous movements is instrumental for coordination of activity in developing sensorimotor spinal cord circuits. PMID- 27713432 TI - Orthodontic therapists - has their introduction affected outcomes? AB - Objective To assess the effect of the introduction of orthodontic therapists (OTs) on the quality of orthodontic treatment outcomes in two specialist orthodontic practices in the UK.Study design Retrospective cross sectional observational study.Setting Multi-centre evaluation at two specialist orthodontic practices in Yorkshire. Data collection was carried out during 2014.Materials and methods The treatment undertaken by three specialist orthodontic clinicians (A, B and C) was evaluated at two time points. The first time point (T1) was before the introduction of OTs when the specialist orthodontic clinicians were solo operators. The second time point (T2) followed the introduction of OTs. Patients at T2 had their treatment planned by a specialist orthodontist and were seen for care by both the orthodontist and an OT who had been qualified for a minimum of three years. A sample size of 30 orthodontic patients per clinician at each time point was chosen. Included participants had completed a course of fixed appliance therapy. They were consecutively selected from cases that had been completed in the specified time frame for each clinician.Main outcome measures The quality of treatment was assessed objectively using the quantitative Peer Assessment Rating index (PAR index). Data extracted from the specialist practice databases also allowed conclusions to be drawn about the length of treatment time and number of appointments in each treatment group.Results and conclusions There appears to have been no change in orthodontic treatment outcomes following the introduction of supervised OTs at two specialist orthodontic practices. PMID- 27713429 TI - Disaggregating the evidence linking biodiversity and ecosystem services. AB - Ecosystem services (ES) are an increasingly popular policy framework for connecting biodiversity with human well-being. These efforts typically assume that biodiversity and ES covary, but the relationship between them remains remarkably unclear. Here we analyse >500 recent papers and show that reported relationships differ among ES, methods of measuring biodiversity and ES, and three different approaches to linking them (spatial correlations, management comparisons and functional experiments). For spatial correlations, biodiversity relates more strongly to measures of ES supply than to resulting human benefits. For management comparisons, biodiversity of 'service providers' predicts ES more often than biodiversity of functionally unrelated taxa, but the opposite is true for spatial correlations. Functional experiments occur at smaller spatial scales than management and spatial studies, which show contrasting responses to scale. Our results illuminate the varying dynamics relating biodiversity to ES, and show the importance of matching management efforts to the most relevant scientific evidence.

AB - An investigation of the clinical experiences of dentists within the national dental foundation training programme in the North West of England. PMID- 27713427 TI - Insulin and TOR signal in parallel through FOXO and S6K to promote epithelial wound healing. AB - The TOR and Insulin/IGF signalling (IIS) network controls growth, metabolism and ageing. Although reducing TOR or insulin signalling can be beneficial for ageing, it can be detrimental for wound healing, but the reasons for this difference are unknown. Here we show that IIS is activated in the cells surrounding an epidermal wound in Drosophila melanogaster larvae, resulting in PI3K activation and redistribution of the transcription factor FOXO. Insulin and TOR signalling are independently necessary for normal wound healing, with FOXO and S6K as their respective effectors. IIS is specifically required in cells surrounding the wound, and the effect is independent of glycogen metabolism. Insulin signalling is needed for the efficient assembly of an actomyosin cable around the wound, and constitutively active myosin II regulatory light chain suppresses the effects of reduced IIS. These findings may have implications for the role of insulin signalling and FOXO activation in diabetic wound healing.

AB - A recent national survey has shown the need for clarification regarding the various disciplines encompassed by restorative dentistry and their respective training pathways. This document aims to address this by outlining the remit of restorative dentistry, in addition to the various job roles involved. This information is being disseminated by the British Society for Restorative Dentistry, and given the relevance to referrers and those looking for insight into the speciality, it has been reproduced here. Roles within the speciality range from dentists with special interests to specialists and consultants, whether primarily academic or clinical. The choice that a new graduate may make to choose a specific route will likely depend on a number of factors, often specific to each individual. Guidance on ways to gain experience and sources of further information are also provided. PMID- 27713437 TI - Snap, send &screen.

AB - Background The 2013 Children's Dental Health Survey is the fifth in a series of national surveys.Aims This paper reports the orthodontic condition of 12- and 15 year-olds and how they and their parents feel about the appearance of their teeth.Methodology A representative sample of children (5y, 8y, 12y, 15y) in England, Wales and Northern Ireland were invited to participate in dental examinations. A modified Index of Orthodontic Treatment Need (IOTN) was used as a measure of orthodontic treatment need for 12- and 15-year-olds. Children and parents were invited to complete a questionnaire about oral health behaviour and attitudes.Results Nine percent of 12-year-olds and 18% of 15-year-olds were undergoing orthodontic treatment at the time of the survey. Forty-four percent of 12-year-olds and 29% of 15-year-olds expressed a desire for straighter teeth, however over half of this group would not qualify for NHS treatment. Unmet treatment need was higher in children eligible for free school meals (P <0.05 at 15y).Conclusions Provision of and demand for orthodontic treatment is increasing, with a significant proportion of children who desire orthodontic care not eligible to receive it. Children from deprived backgrounds have greater unmet orthodontic treatment need. PMID- 27713451 TI - Ecological hypothesis of dentin and root caries. AB - '...questionable whether bacteria play a role in the initial stages of the degradation of the organic components of teeth.' PMID- 27713449 TI - Validity and reliability of remote dental screening by different oral health professionals using a store-and-forward telehealth model. AB - Objective This study was conducted to evaluate the validity and reliability of intraoral photographic assessments by different members of a dental team as a means for dental screening in children.Methods The intraoral photographic records of 126 children (2 to 18 years old) were obtained from routine clinical records taken before dental treatment. Intraoral photographs were obtained using a DSLR camera and then uploaded to a cloud-based server using store-and-forward telehealth technology. Images were reviewed by an expert panel to formulate a benchmark screening baseline, to which the screeners' data were compared. The photographic assessments conducted by a mid-level dental practitioner (MLDP) and dentist, were compared to the benchmark expert panel assessment.Results The screeners' assessments by means of intraoral photography, when compared to the expert panel assessment had a sensitivity value of 82-89% and specificity value of 97%. The inter-examiner agreement between the expert panel assessment and photographic method (assessed by a dentist and MLDP), was almost perfect, with a kappa score ranging from 0.82 to 0.88. The mean DFT/dft score for the children as determined by the expert panel's review and photographic assessment ranging from 5.41 to 5.79, with mean scores between the two assessment methods not significantly different (P = 0.746).Conclusion Our results suggested that oral health professionals (other than dentists) have the potential to screen for caries from intraoral photographs with the same diagnostic accuracy and reliability as dentists. This strategy has implications for supporting the use of MLDPs such as dental therapists or hygienists to screen for oral disease using telehealth.

AB - Dens invaginatus is a developmental malformation, in which there is an infolding of enamel into dentine. These infolds represent stagnation sites for bacteria and can predispose to dental caries. The carious infection can spread via enamel and dentine to contaminate the pulp and cause soft tissue necrosis. The altered and sometimes complex anatomy of affected teeth can make endodontic management challenging. Early diagnosis is therefore essential as prophylactic treatment of the dens can prevent degeneration and pulpal necrosis. The aim of this article is to review the aetiology, classification, diagnosis and management of teeth affected with dens invaginatus. Emphasis will be placed on describing the clinical features of this anomaly. Treatment options, management strategies and the challenges faced in managing this condition will be discussed.

PMID- 27713469 TI - Fast sintering of silver nanoparticle and flake layers by infrared module assistance in large area roll-to-roll gravure printing system. AB - We present fast sintering for silver (Ag) nanoparticle (NP) and flake layers printed using roll-to-roll (R2R) gravure printing. An infrared (IR) sintering module was applied to an R2R system to shorten the sintering duration of an R2R gravure-printed Ag layer. IR sintering of the conductive layer was improved by optimising the process condition. After printing of the Ag NP and Ag flake layers, additional IR sintering was performed in the R2R system. The lowest sheet resistance obtained in the Ag NP layer was 0.294 Omega/?, the distance between the substrate and lamp was 50-mm long, the IR lamp power was 500 W, and the sintering time was 5.4 s. The fastest sintering of 0.34 Omega/? was achieved with 50-mm distance, 1,000-W IR lamp power, and 1.08-s sintering time. In the Ag flake layer, the lowest sheet resistance obtained was 0.288 Omega/? with a 20-mm distance, 1,000-W IR lamp power, and 10.8-s sintering time. Meanwhile, the fastest sintering was obtained with a 3.83 Omega/? sheet resistance, 20-mm distance, 1000-W IR lamp, and 1.08-s sintering time. Thus, the IR sintering module can easily be employed in an R2R system to obtain excellent layer sheet resistance. PMID- 27713472 TI - Real internal microstructure based key mechanism analysis on the micro-damage process of short fibre-reinforced composites. AB - In this work, the underlying micro-damage mechanisms of randomly oriented short fibre-reinforced composites were revealed based on real internal microstructural characteristics obtained by high-resolution (0.7 MUm/pixel) synchrotron radiation X-ray computed tomography (SR-CT). The special 'pore dominant micro-damage processes' were directly observed through SR-CT three-dimensional reconstructed images, which were different from the well-known 'fibre breakage dominant failure mode'. The mechanisms of pore formation and pore evolution were further investigated on the basis of the microstructural parameters extracted from the SR CT results. On one hand, the pore formation mechanism caused by shear stress concentration was proposed by combining the shear-lag model with the microstructural parameters obtained from the experiment, including the fibre length and orientation angle. On the other hand, the 'fibre-end aggregation induced pore connection' mode of crack initiation was proposed through a composites model, which considered the parameters of real internal microstructure, including the critical value of the distance between neighbouring fibre ends and the number of neighbouring fibre ends. The study indicated that the shear stress concentration was significant in the region with a large number of neighbouring fibre ends, thus causing pore connection and crack initiation. PMID- 27713470 TI - In-vivo Dynamics of the Human Hippocampus across the Menstrual Cycle. AB - Sex hormones fluctuate during the menstrual cycle. Evidence from animal studies suggests similar subtle fluctuations in hippocampal structure, predominantly linked to estrogen. Hippocampal abnormalities have been observed in several neuropsychiatric pathologies with prominent sexual dimorphism. Yet, the potential impact of subtle sex-hormonal fluctuations on human hippocampal structure in health is unclear. We tested the feasibility of longitudinal neuroimaging in conjunction with rigorous menstrual cycle monitoring to evaluate potential changes in hippocampal microstructure associated with physiological sex-hormonal changes. Thirty longitudinal diffusion weighted imaging scans of a single healthy female subject were acquired across two full menstrual cycles. We calculated hippocampal fractional anisotropy (FA), a measure sensitive to changes in microstructural integrity, and investigated potential correlations with estrogen. We observed a significant positive correlation between FA values and estrogen in the hippocampus bilaterally, revealing a peak in FA closely paralleling ovulation. This exploratory, single-subject study demonstrates the feasibility of a longitudinal DWI scanning protocol across the menstrual cycle and is the first to link subtle endogenous hormonal fluctuations to changes in FA in vivo. In light of recent attempts to neurally phenotype single humans, our findings highlight menstrual cycle monitoring in parallel with highly sampled individual neuroimaging data to address fundamental questions about the dynamics of plasticity in the adult brain. PMID- 27713474 TI - Carbon-Coated, Diatomite-Derived Nanosilicon as a High Rate Capable Li-ion Battery Anode. AB - Silicon is produced in a variety of ways as an ultra-high capacity lithium-ion battery (LIB) anode material. The traditional carbothermic reduction process required is expensive and energy-intensive; in this work, we use an efficient magnesiothermic reduction to convert the silica-based frustules within diatomaceous earth (diatomite, DE) to nanosilicon (nanoSi) for use as LIB anodes. Polyacrylic acid (PAA) was used as a binder for the DE-based nanoSi anodes for the first time, being attributed for the high silicon utilization under high current densities (up to 4C). The resulting nanoSi exhibited a high BET specific surface area of 162.6 cm2 g-1, compared to a value of 7.3 cm2 g-1 for the original DE. DE contains SiO2 architectures that make ideal bio-derived templates for nanoscaled silicon. The DE-based nanoSi anodes exhibit good cyclability, with a specific discharge capacity of 1102.1 mAh g-1 after 50 cycles at a C-rate of C/5 (0.7 A gSi-1) and high areal loading (2 mg cm-2). This work also demonstrates the fist rate capability testing for a DE-based Si anode; C-rates of C/30 - 4C were tested. At 4C (14.3 A gSi-1), the anode maintained a specific capacity of 654.3 mAh g-1 - nearly 2x higher than graphite's theoretical value (372 mAh g-1). PMID- 27713473 TI - Identification of the nuclear localisation signal of O-GlcNAc transferase and its nuclear import regulation. AB - Nucleocytoplasmic O-GlcNAc transferase (OGT) attaches a single GlcNAc to hydroxyl groups of serine and threonine residues. Although the cellular localisation of OGT is important to regulate a variety of cellular processes, the molecular mechanisms regulating the nuclear localisation of OGT is unclear. Here, we characterised three amino acids (DFP; residues 451-453) as the nuclear localisation signal of OGT and demonstrated that this motif mediated the nuclear import of non-diffusible beta-galactosidase. OGT bound the importin alpha5 protein, and this association was abolished when the DFP motif of OGT was mutated or deleted. We also revealed that O-GlcNAcylation of Ser389, which resides in the tetratricopeptide repeats, plays an important role in the nuclear localisation of OGT. Our findings may explain how OGT, which possesses a NLS, exists in the nucleus and cytosol simultaneously. PMID- 27713471 TI - Hepatic Deletion of Janus Kinase 2 Counteracts Oxidative Stress in Mice. AB - Genetic deletion of the tyrosine kinase JAK2 or the downstream transcription factor STAT5 in liver impairs growth hormone (GH) signalling and thereby promotes fatty liver disease. Hepatic STAT5 deficiency accelerates liver tumourigenesis in presence of high GH levels. To determine whether the upstream kinase JAK2 exerts similar functions, we crossed mice harbouring a hepatocyte-specific deletion of JAK2 (JAK2Deltahep) to GH transgenic mice (GHtg) and compared them to GHtgSTAT5Deltahep mice. Similar to GHtgSTAT5Deltahep mice, JAK2 deficiency resulted in severe steatosis in the GHtg background. However, in contrast to STAT5 deficiency, loss of JAK2 significantly delayed liver tumourigenesis. This was attributed to: (i) activation of STAT3 in STAT5-deficient mice, which was prevented by JAK2 deficiency and (ii) increased detoxification capacity of JAK2 deficient livers, which diminished oxidative damage as compared to GHtgSTAT5Deltahep mice, despite equally severe steatosis and reactive oxygen species (ROS) production. The reduced oxidative damage in JAK2-deficient livers was linked to increased expression and activity of glutathione S-transferases (GSTs). Consistent with genetic deletion of Jak2, pharmacological inhibition and siRNA-mediated knockdown of Jak2 led to significant upregulation of Gst isoforms and to reduced hepatic oxidative DNA damage. Therefore, blocking JAK2 function increases detoxifying GSTs in hepatocytes and protects against oxidative liver damage.

AB - Reticulate evolution, introgressive hybridisation, and phenotypic plasticity have been documented in scleractinian corals and have challenged our ability to interpret speciation processes. Stylophora is a key model system in coral biology and physiology, but genetic analyses have revealed that cryptic lineages concealed by morphological stasis exist in the Stylophora pistillata species complex. The Red Sea represents a hotspot for Stylophora biodiversity with six morphospecies described, two of which are regionally endemic. We investigated Stylophora species boundaries from the Red Sea and the associated Symbiodinium by sequencing seven DNA loci. Stylophora morphospecies from the Red Sea were not resolved based on mitochondrial phylogenies and showed nuclear allele sharing. Low genetic differentiation, weak isolation, and strong gene flow were found among morphospecies although no signals of genetic recombination were evident among them. Stylophora mamillata harboured Symbiodinium clade C whereas the other two Stylophora morphospecies hosted either Symbiodinium clade A or C. These evolutionary patterns suggest that either gene exchange occurs through reticulate evolution or that multiple ecomorphs of a phenotypically plastic species occur in the Red Sea. The recent origin of the lineage leading to the Red Sea Stylophora may indicate an ongoing speciation driven by environmental changes and incomplete lineage sorting. PMID- 27713476 TI - The fates of 15N-labeled fertilizer in a wheat-soil system as influenced by fertilization practice in a loamy soil. AB - Appropriate fertilization practice is crucial to achieve maximum wheat grain yield with minimum nitrogen (N) loss. A field 15N micro-plot experiment was conducted to determine the effects of application methods [split application (SA) and band application (BA)] and N rates (60, 150 and 240 kg ha-1) on the wheat grain yield, urea-15N fate and N efficiency in Jiangyan County, China. At high N rates, wheat grain yield was significantly higher for SA than BA treatment, but there was no difference at the lower N rates. Plant N derived from fertilizer was higher in SA than in BA treatment. The high N fertilizer application increased total N uptake by wheat derived from fertilizer, but wheat plant N derived from soil was not affected by the N rate. Fertilizer-N recovery in SA treatment was higher than in BA treatment. Residual N recovery in the 0-80 cm soil layer was 31 51%, which decreased with increasing N rate. The highest N loss was found for BA treatment at the N application of 240 kg ha-1. The one-time BA of N fertilizer, especially for higher N rates, led to reduced wheat grain yield and N efficiency, and increased the N loss. PMID- 27713478 TI - Polymer-dispersed liquid crystal elastomers. AB - The need for mechanical manipulation during the curing of conventional liquid crystal elastomers diminishes their applicability in the field of shape programmable soft materials and future applications in additive manufacturing. Here we report on polymer-dispersed liquid crystal elastomers, novel composite materials that eliminate this difficulty. Their thermal shape memory anisotropy is imprinted by curing in external magnetic field, providing for conventional moulding of macroscopically sized soft, thermomechanically active elastic objects of general shapes. The binary soft-soft composition of isotropic elastomer matrix, filled with freeze-fracture-fabricated, oriented liquid crystal elastomer microparticles as colloidal inclusions, allows for fine-tuning of thermal morphing behaviour. This is accomplished by adjusting the concentration, spatial distribution and orientation of microparticles or using blends of microparticles with different thermomechanical characteristics. We demonstrate that any Gaussian thermomechanical deformation mode (bend, cup, saddle, left and right twist) of a planar sample, as well as beat-like actuation, is attainable with bilayer microparticle configurations. PMID- 27713477 TI - Antiestrogen Resistant Cell Lines Expressing Estrogen Receptor alpha Mutations Upregulate the Unfolded Protein Response and are Killed by BHPI. AB - Outgrowth of metastases expressing ERalpha mutations Y537S and D538G is common after endocrine therapy for estrogen receptor alpha (ERalpha) positive breast cancer. The effect of replacing wild type ERalpha in breast cancer cells with these mutations was unclear. We used the CRISPR-Cas9 genome editing system and homology directed repair to isolate and characterize 14 T47D cell lines in which ERalphaY537S or ERalphaD538G replace one or both wild-type ERalpha genes. In 2 dimensional, and in quantitative anchorage-independent 3-dimensional cell culture, ERalphaY537S and ERalphaD538G cells exhibited estrogen-independent growth. A progestin further increased their already substantial proliferation in micromolar 4-hydroxytamoxifen and fulvestrant/ICI 182,780 (ICI). Our recently described ERalpha biomodulator, BHPI, which hyperactivates the unfolded protein response (UPR), completely blocked proliferation. In ERalphaY537S and ERalphaD538G cells, estrogen-ERalpha target genes were constitutively active and partially antiestrogen resistant. The UPR marker sp-XBP1 was constitutively activated in ERalphaY537S cells and further induced by progesterone in both cell lines. UPR-regulated genes associated with tamoxifen resistance, including the oncogenic chaperone BiP/GRP78, were upregulated. ICI displayed a greater than 2 fold reduction in its ability to induce ERalphaY537S and ERalphaD538G degradation. Progestins, UPR activation and perhaps reduced ICI-stimulated ERalpha degradation likely contribute to antiestrogen resistance seen in ERalphaY537S and ERalphaD538G cells. PMID- 27713479 TI - Intrinsic noise and deviations from criticality in Boolean gene-regulatory networks. AB - Gene regulatory networks can be successfully modeled as Boolean networks. A much discussed hypothesis says that such model networks reproduce empirical findings the best if they are tuned to operate at criticality, i.e. at the borderline between their ordered and disordered phases. Critical networks have been argued to lead to a number of functional advantages such as maximal dynamical range, maximal sensitivity to environmental changes, as well as to an excellent tradeoff between stability and flexibility. Here, we study the effect of noise within the context of Boolean networks trained to learn complex tasks under supervision. We verify that quasi-critical networks are the ones learning in the fastest possible way -even for asynchronous updating rules- and that the larger the task complexity the smaller the distance to criticality. On the other hand, when additional sources of intrinsic noise in the network states and/or in its wiring pattern are introduced, the optimally performing networks become clearly subcritical. These results suggest that in order to compensate for inherent stochasticity, regulatory and other type of biological networks might become subcritical rather than being critical, all the most if the task to be performed has limited complexity. PMID- 27713480 TI - The transcription factor Ets21C drives tumor growth by cooperating with AP-1. AB - Tumorigenesis is driven by genetic alterations that perturb the signaling networks regulating proliferation or cell death. In order to block tumor growth, one has to precisely know how these signaling pathways function and interplay. Here, we identified the transcription factor Ets21C as a pivotal regulator of tumor growth and propose a new model of how Ets21C could affect this process. We demonstrate that a depletion of Ets21C strongly suppressed tumor growth while ectopic expression of Ets21C further increased tumor size. We confirm that Ets21C expression is regulated by the JNK pathway and show that Ets21C acts via a positive feed-forward mechanism to induce a specific set of target genes that is critical for tumor growth. These genes are known downstream targets of the JNK pathway and we demonstrate that their expression not only depends on the transcription factor AP-1, but also on Ets21C suggesting a cooperative transcriptional activation mechanism. Taken together we show that Ets21C is a crucial player in regulating the transcriptional program of the JNK pathway and enhances our understanding of the mechanisms that govern neoplastic growth. PMID- 27713481 TI - Computational prediction shines light on type III secretion origins. AB - Type III secretion system is a key bacterial symbiosis and pathogenicity mechanism responsible for a variety of infectious diseases, ranging from food borne illnesses to the bubonic plague. In many Gram-negative bacteria, the type III secretion system transports effector proteins into host cells, converting resources to bacterial advantage. Here we introduce a computational method that identifies type III effectors by combining homology-based inference with de novo predictions, reaching up to 3-fold higher performance than existing tools. Our work reveals that signals for recognition and transport of effectors are distributed over the entire protein sequence instead of being confined to the N terminus, as was previously thought. Our scan of hundreds of prokaryotic genomes identified previously unknown effectors, suggesting that type III secretion may have evolved prior to the archaea/bacteria split. Crucially, our method performs well for short sequence fragments, facilitating evaluation of microbial communities and rapid identification of bacterial pathogenicity - no genome assembly required. pEffect and its data sets are available at http://services.bromberglab.org/peffect. PMID- 27713482 TI - Understanding the multiferroicity in TmMn2O5 by a magnetically induced ferrielectric model. AB - The magnetically induced electric polarization behaviors in multiferroic TmMn2O5 in response to varying temperature and magnetic field are carefully investigated by means of a series of characterizations including the high precision pyroelectric current technique. Here polycrystalline rather than single crystal samples are used for avoiding the strong electrically self-polarized effect in single crystals, and various parallel experiments on excluding the thermally excited current contributions are performed. The temperature-dependent electric polarization flop as a major character is identified for different measuring paths. The magneto-current measurements indicate that the electric polarization in the low temperature magnetic phase region has different origin from that in the high temperature magnetic phase. It is suggested that the electric polarization does have multiple components which align along different orientations, including the Mn3+-Mn4+-Mn3+ exchange striction induced polarization PMM, the Tm3+-Mn4+-Tm3+ exchange striction induced polarization PTM, and the low temperature polarization PLT probably associated with the Tm3+ commensurate phase. The observed electric polarization flop can be reasonably explained by the ferrielectric model proposed earlier for DyMn2O5, where PMM and PTM are the two antiparallel components both along the b-axis and PLT may align along the a-axis. Finally, several issues on the unusual temperature dependence of ferroelectric polarizations are discussed. PMID- 27713483 TI - The smallest chimera state for coupled pendula. AB - Chimera states in the systems of coupled identical oscillators are spatiotemporal patterns in which different groups of oscillators can exhibit coexisting synchronous and incoherent behaviors despite homogeneous coupling. Although these states are typically observed in large ensembles of oscillators, recently it has been suggested that chimera states may occur in the systems with small numbers of oscillators. Here, considering three coupled pendula showing chaotic behavior, we find the pattern of the smallest chimera state, which is characterized by the coexistence of two synchronized and one incoherent oscillator. We show that this chimera state can be observed in simple experiments with mechanical oscillators, which are controlled by elementary dynamical equations derived from Newton's laws. Our finding suggests that chimera states are observable in small networks relevant to various real-world systems.

PMID- 27713484 TI - A Novel Genetic Variant in Long Non-coding RNA Gene NEXN-AS1 is Associated with Risk of Lung Cancer. AB - Lung cancer etiology is multifactorial, and growing evidence has indicated that long non-coding RNAs (lncRNAs) are important players in lung carcinogenesis. We performed a large-scale meta-analysis of 690,564 SNPs in 15,531 autosomal lncRNAs by using datasets from six previously published genome-wide association studies (GWASs) from the Transdisciplinary Research in Cancer of the Lung (TRICL) consortium in populations of European ancestry. Previously unreported significant SNPs (P value < 1 * 10-7) were further validated in two additional independent lung cancer GWAS datasets from Harvard University and deCODE. In the final meta analysis of all eight GWAS datasets with 17,153 cases and 239,337 controls, a novel risk SNP rs114020893 in the lncRNA NEXN-AS1 region at 1p31.1 remained statistically significant (odds ratio = 1.17; 95% confidence interval = 1.11 1.24; P = 8.31 * 10-9). In further in silico analysis, rs114020893 was predicted to change the secondary structure of the lncRNA. Our finding indicates that SNP rs114020893 of NEXN-AS1 at 1p31.1 may contribute to lung cancer susceptibility.

PMID- 27713486 TI - The phasor-FLIM fingerprints reveal shifts from OXPHOS to enhanced glycolysis in Huntington Disease. AB - Huntington disease (HD) is an autosomal neurodegenerative disorder caused by the expansion of Polyglutamine (polyQ) in exon 1 of the Huntingtin protein. Glutamine repeats below 36 are considered normal while repeats above 40 lead to HD. Impairment in energy metabolism is a common trend in Huntington pathogenesis; however, this effect is not fully understood. Here, we used the phasor approach and Fluorescence Lifetime Imaging Microscopy (FLIM) to measure changes between free and bound fractions of NADH as a indirect measure of metabolic alteration in living cells. Using Phasor-FLIM, pixel maps of metabolic alteration in HEK293 cell lines and in transgenic Drosophila expressing expanded and unexpanded polyQ HTT exon1 in the eye disc were developed. We found a significant shift towards increased free NADH, indicating an increased glycolytic state for cells and tissues expressing the expanded polyQ compared to unexpanded control. In the nucleus, a further lifetime shift occurs towards higher free NADH suggesting a possible synergism between metabolic dysfunction and transcriptional regulation. Our results indicate that metabolic dysfunction in HD shifts to increased glycolysis leading to oxidative stress and cell death. This powerful label free method can be used to screen native HD tissue samples and for potential drug screening.

Cameroon is one of the most active volcanoes in Africa and poses a possible threat to about half a million people in the area, yet knowledge of the volcano's underlying magma supply system is sparse. To characterize Mt. Cameroon's magma plumbing system, we employed mineral-melt equilibrium thermobarometry on the products of the volcano's two most recent eruptions of 1999 and 2000. Our results suggest pre-eruptive magma storage between 20 and 39 km beneath Mt. Cameroon, which corresponds to the Moho level and below. Additionally, the 1999 eruption products reveal several shallow magma pockets between 3 and 12 km depth, which are not detected in the 2000 lavas. This implies that small-volume magma batches actively migrate through the plumbing system during repose intervals. Evolving and migrating magma parcels potentially cause temporary unrest and short-lived explosive outbursts, and may be remobilized during major eruptions that are fed from sub-Moho magma reservoirs. PMID- 27713493 TI - SDF-1alpha-induced dual pairs of E-selectin/ligand mediate endothelial progenitor cell homing to critical ischemia. AB - Homing of endothelial progenitor cells (EPC) to the ischemic tissues is a key event in neovascularization and tissue regeneration. In response to ischemic insult, injured tissues secrete several chemo-cytokines, including stromal cell derived factor-1alpha (SDF-1alpha), which triggers mobilization and homing of bone marrow-derived EPC (BMD-EPC). We previously reported that SDF-1alpha-induced EPC homing is mediated by a panel of adhesion molecules highly or selectively expressed on the activated endothelium in ischemic tissues, including E-selectin. Elevated E-selectin on wound vasculature serve as docking sites for circulating EPC, which express counterpart E-selectin ligands. Here, we show that SDF-1alpha presented in wound tissue and released into circulation can act both locally and remotely to induce ischemic tissue endothelium and BMD-EPC to express both E selectin and its ligands. By performing BM transplantation using E-selectin-/- and E-selectin+/+ mice as the donors and recipients respectively, we demonstrate that upregulated dual E-selectin/ligand pairs reciprocally expressed on ischemic tissue endothelium and BMD-EPC act as double-locks to secure targeted EPC- endothelium interactions by which to facilitate EPC homing and promote neovascularization and tissue repair. These findings describe a novel mechanism for BMD-EPC homing and indicate that dual E-selectin/ligand pairs may be effective targets/tools for therapeutic neovascularization and targeted cell delivery.

AB - A numerical model for amplification of ultrashort pulses with high repetition rates in fiber amplifiers is presented. The pulse propagation is modeled by jointly solving the steady-state rate equations and the generalized nonlinear Schrodinger equation, which allows accurate treatment of nonlinear and dispersive effects whilst considering arbitrary spatial and spectral gain dependencies. Comparison of data acquired by using the developed model and experimental results prove to be in good agreement. PMID- 27713495 TI - Allosteric regulation in NMDA receptors revealed by the genetically encoded photo cross-linkers. AB - Allostery is essential to neuronal receptor function, but its transient nature poses a challenge for characterization. The N-terminal domains (NTDs) distinct from ligand binding domains are a major locus for allosteric regulation of NMDA receptors (NMDARs), where different modulatory binding sites have been observed. The inhibitor ifenprodil, and related phenylethanoamine compounds specifically targeting GluN1/GluN2B NMDARs have neuroprotective activity. However, whether they use differential structural pathways than the endogenous inhibitor Zn2+ for regulation is unknown. We applied genetically encoded unnatural amino acids (Uaas) and monitored the functional changes in living cells with photo-cross linkers specifically incorporated at the ifenprodil binding interface between GluN1 and GluN2B subunits. We report constraining the NTD domain movement, by a light induced crosslinking bond that introduces minimal perturbation to the ligand binding, specifically impedes the transduction of ifenprodil but not Zn2+ inhibition. Subtle distance changes reveal interfacial flexibility and NTD rearrangements in the presence of modulators. Our results present a much richer dynamic picture of allostery than conventional approaches targeting the same interface, and highlight key residues that determine functional and subtype specificity of NMDARs. The light-sensitive mutant neuronal receptors provide complementary tools to the photo-switchable ligands for opto-neuropharmacology.

AB - The "reverse dipping" blood pressure (BP) pattern has been studied among the general population and in individuals suffering from hypertension. However, the prognosis of this pattern in chronic kidney disease (CKD) patients is not known. We monitored BP throughout the day and followed health outcomes in 588 CKD patients admitted to our hospital. Time to all-cause mortality, cardiovascular mortality, renal events and cardiovascular events was recorded. Multivariate adjusted Cox regression analyses were carried out to detect the prognostic value of a reverse dipping BP pattern. Prevalence of a "dipper", "non-dipper" and "reverse dippers" was 34.69%, 43.54% and 18.03%, respectively. Patients with a reverse dipping pattern had a higher prevalence of total mortality, cardiovascular mortality, renal events and cardiovascular events than patients with a dipping pattern (P < 0.025). Multivariate-adjusted Cox regression analyses showed that reverse dippers (versus dippers) were associated with a higher risk of total mortality (hazard ratio [HR], 5.08; 95% confidence interval [CI], 1.79~14.47), cardiovascular mortality (4.17; 1.25~13.88), renal events (3.00; 1.59~5.65) and cardiovascular events (4.12; 1.78~9.51) even after adjustment by 24-h systolic BP. These data suggest that a reverse dipping BP pattern, independent of 24-h levels of systolic BP, has prognostic value in CKD patients not undergoing dialysis. PMID- 27713500 TI - Genome Sequencing of the Pyruvate-producing Strain Candida glabrata CCTCC M202019 and Genomic Comparison with Strain CBS138. AB - Candida glabrata CCTCC M202019 as an industrial yeast strain that is widely used to produce alpha-oxocarboxylic acid. Strain M202019 has been proven to have a higher pyruvate-producing capacity than the reference strain CBS138. To characterize the genotype of the M202019 strain, we generated a draft sequence of its genome, which has a size of 12.1 Mbp and a GC content of 38.47%. Evidence accumulated during genome annotation suggests that strain M202019 has strong capacities for glucose transport and pyruvate biosynthesis, defects in pyruvate catabolism, as well as variations in genes involved in nutrient and dicarboxylic acid transport, oxidative phosphorylation, and other relevant aspects of carbon metabolism, which might promote pyruvate accumulation. In addition to differences in its central carbon metabolism, a genomic analysis revealed genetic differences in adhesion metabolism. Forty-nine adhesin-like proteins of strain M202019 were identified classified into seven subfamilies. Decreased amounts of adhesive proteins, and deletions or changes of low-complexity repeats and functional domains might lead to lower adhesion and reduced pathogenicity. Further virulence experiments validated the biological safety of strain M202019. Analysis of the C. glabrata CCTCC M202019 genome sequence provides useful insights into its genetic context, physical characteristics, and potential metabolic capacity. PMID- 27713499 TI - Disruption of ArhGAP15 results in hyperactive Rac1, affects the architecture and function of hippocampal inhibitory neurons and causes cognitive deficits. AB - During brain development, the small GTPases Rac1/Rac3 play key roles in neuronal migration, neuritogenesis, synaptic formation and plasticity, via control of actin cytoskeleton dynamic. Their activity is positively and negatively regulated by GEFs and GAPs molecules, respectively. However their in vivo roles are poorly known. The ArhGAP15 gene, coding for a Rac-specific GAP protein, is expressed in both excitatory and inhibitory neurons of the adult hippocampus, and its loss results in the hyperactivation of Rac1/Rac3. In the CA3 and dentate gyrus (DG) regions of the ArhGAP15 mutant hippocampus the CR+, PV+ and SST+ inhibitory neurons are reduced in number, due to reduced efficiency and directionality of their migration, while pyramidal neurons are unaffected. Loss of ArhGAP15 alters neuritogenesis and the balance between excitatory and inhibitory synapses, with a net functional result consisting in increased spike frequency and bursts, accompanied by poor synchronization. Thus, the loss of ArhGAP15 mainly impacts on interneuron-dependent inhibition. Adult ArhGAP15-/- mice showed defective hippocampus-dependent functions such as working and associative memories. These findings indicate that a normal architecture and function of hippocampal inhibitory neurons is essential for higher hippocampal functions, and is exquisitely sensitive to ArhGAP15-dependent modulation of Rac1/Rac3. PMID- 27713501 TI - In vivo analysis of internal ribosome entry at the Hairless locus by genome engineering in Drosophila. AB - Cell communication in metazoans requires the highly conserved Notch signaling pathway, which is subjected to strict regulation of both activation and silencing. In Drosophila melanogaster, silencing involves the assembly of a repressor complex by Hairless (H) on Notch target gene promoters. We previously found an in-frame internal ribosome entry site in the full length H transcript resulting in two H protein isoforms (Hp120 and Hp150). Hence, H may repress Notch signalling activity in situations where cap-dependent translation is inhibited. Here we demonstrate the in vivo importance of both H isoforms for proper fly development. To this end, we replaced the endogenous H locus by constructs specifically affecting translation of either Hp150 or Hp120 isoforms using genome engineering. Our findings indicate the functional relevance of both H proteins. Based on bristle phenotypes, the predominant isoform Hp150 appears to be of particular importance. In contrast, growth regulation and venation of the wing require the concomitant activity of both isoforms. Finally, the IRES dependent production of Hp120 during mitosis was verified in vivo. Together our data confirm IRES mediated translation of H protein in vivo, supporting strict regulation of Notch in different cellular settings. PMID- 27713502 TI - Nutrient reduction induced stringent responses promote bacterial quorum-sensing divergence for population fitness. AB - Bacteria use a cell-cell communication system termed quorum-sensing (QS) to adjust population size by coordinating the costly but beneficial cooperative behaviors. It has long been suggested that bacterial social conflict for expensive extracellular products may drive QS divergence and cause the "tragedy of the commons". However, the underlying molecular mechanism of social divergence and its evolutionary consequences for the bacterial ecology still remain largely unknown. By using the model bacterium Pseudomonas aeruginosa PAO1, here we show that nutrient reduction can promote QS divergence for population fitness during evolution but requiring adequate cell density. Mechanically, decreased nutrient supplies can induce RpoS-directed stringent response and enhance the selection pressure on lasR gene, and lasR mutants are evolved in association with the DNA mismatch repair "switch-off". The lasR mutants have higher relative fitness than QS-intact individuals due to their energy-saving characteristic under nutrient decreased condition. Furthermore an optimal incorporation of lasR mutants is capable of maximizing the fitness of entire population during in vitro culture and the colonization in mouse lung. Consequently, rather than worsen the population health, QS-coordinated social divergence is an elaborate evolutionary strategy that renders the entire bacterial population more fit in tough times. PMID- 27713503 TI - Left Atrial trajectory impairment in Hypertrophic Cardiomyopathy disclosed by Geometric Morphometrics and Parallel Transport. AB - The analysis of full Left Atrium (LA) deformation and whole LA deformational trajectory in time has been poorly investigated and, to the best of our knowledge, seldom discussed in patients with Hypertrophic Cardiomyopathy. Therefore, we considered 22 patients with Hypertrophic Cardiomyopathy (HCM) and 46 healthy subjects, investigated them by three-dimensional Speckle Tracking Echocardiography, and studied the derived landmark clouds via Geometric Morphometrics with Parallel Transport. Trajectory shape and trajectory size were different in Controls versus HCM and their classification powers had high AUC (Area Under the Receiving Operator Characteristic Curve) and accuracy. The two trajectories were much different at the transition between LA conduit and booster pump functions. Full shape and deformation analyses with trajectory analysis enabled a straightforward perception of pathophysiological consequences of HCM condition on LA functioning. It might be worthwhile to apply these techniques to look for novel pathophysiological approaches that may better define atrio ventricular interaction. PMID- 27713504 TI - Metabolomics of aging assessed in individual parasitoid wasps. AB - Metabolomics studies of low-biomass organisms, such as small insects, have previously relied on the pooling of biological samples to overcome detection limits, particularly using NMR. We show that the differentiation of metabolite profiles of individual 1 mg parasitoid wasps of different ages is possible when using a modified sample preparation and a combination of untargeted NMR and LC-MS based metabolomics. Changes were observed between newly emerged and older wasps in glycerolipids, amino acids and circulatory sugars. This advance in chemical profiling has important implications for the study of the behaviour and ecology of parasitoids and many other species of small organisms because predictions and observations are typically made at the level of the individual. Thus, the metabolomic state of low-biomass individuals can now be related to their behaviour and ecological performance. We discuss specifically the utility of age related metabolomic profiling but our new approach can be applied to a wide range of biological research. PMID- 27713505 TI - Zika virus infection during the period of maximal brain growth causes microcephaly and corticospinal neuron apoptosis in wild type mice. AB - Zika virus (ZIKV) infection in pregnant women has been established as a cause of microcephaly in newborns. Here we test the hypothesis that neurodevelopmental stages when the brain is undergoing rapid growth are particularly vulnerable to the effects of ZIKV infection. We injected ZIKV intracranially into wild type C57BL/6 mice at two different time points: early postnatal development, when the brain is growing at its maximal rate, and at weaning, when the brain has largely reached adult size. Both time points showed widespread immunoreactivity for ZIKV and cleaved caspase 3 (CC3, a marker of apoptosis) throughout the brain. However, in early postnatal ZIKV injected mice, some brain areas and cell types display particularly large increases in apoptosis that we did not observe in older animals. Corticospinal pyramidal neurons, a cell type implicated in human microcephaly associated with ZIKV infection, are an example of one such cell type. Proliferating cells in the ventricular zone stem cell compartment are also depleted. These findings are consistent with the hypothesis that periods of rapid brain growth are especially susceptible to neurodevelopmental effects of ZIKV infection, and establish a valuable model to investigate mechanisms underlying neurodevelopmental effects of ZIKV infection and explore candidate therapeutics. PMID- 27713506 TI - PAK1 confers chemoresistance and poor outcome in non-small cell lung cancer via beta-catenin-mediated stemness. AB - PAK1 confers resistance to the estrogen antagonist tamoxifen in breast cancer. However, a role for PAK1 remains to be elucidated for chemoresistance and prognosis in non-small cell lung cancer (NSCLC). We provide evidence that PAK1 confers cisplatin resistance by increasing beta-catenin expression through ERK/GSK3beta signaling. The increased beta-catenin expression promotes sphere cell formation and expression of stemness markers and this beta-catenin-induced stemness is responsible for PAK1-mediated cisplatin resistance. We enrolled 87 NSCLC patients who had received cisplatin-based chemotherapy to confirm the association between PAK1 expression and response to chemotherapy and outcomes. PAK1 expression, evaluated by immunohistochemistry, was positively correlated with pERK and beta-catenin expression in lung tumors. Patients with high-PAK1, high-pERK, and high-nuclear beta-catenin tumors more frequently showed an unfavorable response to cisplatin-based chemotherapy when compared to their counterparts. Kaplan-Meier and Cox regression analysis also indicated a poorer overall survival (OS) and relapse free survival (RFS) in patients with high-PAK1, high-pERK, and high-nuclear beta-catenin tumors. In conclusion, PAK1 confers cisplatin resistance in NSCLC via beta-catenin-mediated stemness. Therefore, we suggest that clinical use of a combination of the MEK/ERK inhibitor AZD6244 and cisplatin might improve sensitivity to cisplatin-based chemotherapy and outcomes in NSCLC patients who harbor high-PAK1-expressing tumors.

AB - Parkinson's disease is one of the most common neurodegenerative disorders and several mutations in different genes have been identified to contribute to the disease. A loss of function parkin RING1 domain mutant (C289G) is associated with autosomal-recessive juvenile-onset Parkinsonism (AR-JP) and displays altered solubility and sequesters into aggregates. Single overexpression of almost each individual member of the Hsp40 (DNAJ) family of chaperones efficiently reduces parkin C289G aggregation and requires interaction with and activity of endogenously expressed Hsp70 s. For DNAJB6 and DNAJB8, potent suppressors of aggregation of polyglutamine proteins for which they rely mainly on an S/T-rich region, it was found that the S/T-rich region was dispensable for suppression of parkin C289G aggregation. Our data implies that different disease-causing proteins pose different challenges to the protein homeostasis system and that DNAJB6 and DNAJB8 are highly versatile members of the DNAJ protein family with multiple partially non-overlapping modes of action with respect to handling disease-causing proteins, making them interesting potential therapeutic targets.

AB - Islanding is known as a management procedure of the power system that is implemented at the distribution level to preserve sensible loads from outages and to guarantee the continuity in electricity supply, when a high amount of distributed generation occurs. In this paper we study islanding on the level of the transmission grid and shall show that it is a suitable measure to enhance energy security and grid resilience. We consider the German and Italian transmission grids. We remove links either randomly to mimic random failure events, or according to a topological characteristic, their so-called betweenness centrality, to mimic an intentional attack and test whether the resulting fragments are self-sustainable. We test this option via the tool of optimized DC power flow equations. When transmission lines are removed according to their betweenness centrality, the resulting islands have a higher chance of being dynamically self-sustainable than for a random removal. Less connections may even increase the grid's stability. These facts should be taken into account in the design of future power grids.

AB - Breast carcinoma amplified sequence 2 (BCAS2) is a core component of the hPrP19 complex that controls RNA splicing. Here, we performed an exon array assay and showed that beta-catenin is a target of BCAS2 splicing regulation. The regulation of dendrite growth and morphology by beta-catenin is well documented. Therefore, we generated conditional knockout (cKO) mice to eliminate the BCAS2 expression in the forebrain to investigate the role of BCAS2 in dendrite growth. BCAS2 cKO mice showed a microcephaly-like phenotype with a reduced volume in the dentate gyrus (DG) and low levels of learning and memory, as evaluated using Morris water maze analysis and passive avoidance, respectively. Golgi staining revealed shorter dendrites, less dendritic complexity and decreased spine density in the DG of BCAS2 cKO mice. Moreover, the cKO mice displayed a short dendrite length in newborn neurons labeled by DCX, a marker of immature neurons, and BrdU incorporation. To further examine the mechanism underlying BCAS2-mediated dendritic malformation, we overexpressed beta-catenin in BCAS2-depleted primary neurons and found that the dendritic growth was restored. In summary, BCAS2 is an upstream regulator of beta-catenin gene expression and plays a role in dendrite growth at least partly through beta-catenin. PMID- 27713510 TI - Hierarchically-structured silver nanoflowers for highly conductive metallic inks with dramatically reduced filler concentration. AB - Silver has long been employed as an electrically conductive component, and morphology-dependent properties have been actively investigated. Here we present a novel scalable synthesis method of flower-shaped silver nanoparticles (silver nanoflowers, Ag NFs). The preferential affinity of citrate molecules on (111) surface of silver enabled spontaneous anisotropic growth of Ag NFs (bud size: 250~580 nm, single crystalline petal thickness: 9~22 nm) with high reproducibility and a high yield of >99.5%. The unique hierarchical structure resulted in coalescence of petals over 80~120 degrees C which was practically employed in conductive inks to construct percolation pathways among Ag NFs. The ink with only 3 wt% of Ag NFs provided two orders of magnitude greater conductivity (1.008 * 105 Scm-1), at a low curing temperature of 120 degrees C, compared with the silver nanoparticle ink with a much higher silver concentration (50 wt%). This extraordinary property may provide an excellent opportunity for Ag NFs for practical applications in printable and flexible electronics. PMID- 27713511 TI - Cell surface GRP78 as a biomarker and target for suppressing glioma cells. AB - High-grade glioma is a highly malignant and metastatic brain cancer, resistant to many existing anticancer treatments. In such glioma cancer cells, the glucose regulated protein 78 kDa (GRP78) is particularly highly up-regulated. Former studies have thus targeted mutation-free GRP78 not only to detect glioma cancer cells specifically but also to enhance cytotoxic effect. We focus on cell surface expressed GRP78 as a target for suppressing high-grade glioma cell lines. Glioblastoma multiforme (GBM) cell line, highly malignant glioma cells, was first injected into 5-week-old athymic mice to confirm and compare GRP78 expression in vivo in xenografted and normal brain tissue. Immunofluorescence and immunoblotting were utilized to detect surface-localized GRP78 in diverse high grade glioma cell lines. By treating glioma cell lines with the polyclonal N-20 antibody against surface-localized GRP78, we subsequently studied the significance of surface GRP78 to the survival and growth of the glioma cell lines. We found that inhibiting the function of surface GRP78 suppressed cancer cell survival and growth proving that the surface-expressed GRP78 is a vital receptor involved in the proliferation of high-grade glioma. Our findings provide opportunities to target surface GRP78 as a biomarker for high-grade glioma and to develop effective cell-specific anticancer therapy. PMID- 27713512 TI - Marangoni effect visualized in two-dimensions Optical tweezers for gas bubbles. AB - In the report we demonstrate how, using laser light, effectively trap gas bubbles and transport them through a liquid phase to a desired destination by shifting the laser beam position. The physics underlying the effect is complex but quite general as it comes from the limited to two-dimension, well-known, Marangoni effect. The experimental microscope-based system consists of a thin layer of liquid placed between two glass plates containing a dye dissolved in a solvent and a laser light beam that is strongly absorbed by the dye. This point-like heat source locally changes surface tension of nearby liquid-air interface. Because of temperature gradients a photo-triggered Marangoni flows are induced leading to self-amplification of the effect and formation of large-scale whirls. The interface is bending toward beam position allowing formation of a gas bubble upon suitable beam steering. Using various techniques (employing luminescent particles or liquid crystals), we visualize liquid flows propelled by the tangential to interface forces. This helped us to understand the physics of the phenomenon and analyze accompanying effects leading to gas bubble trapping. The manipulation of sessile droplets moving on the glass surface induced via controlled with laser light interface bending (i.e. "droplet catapult") is demonstrated as well. PMID- 27713513 TI - Computational identification of putative lincRNAs in mouse embryonic stem cell. AB - As the regulatory factors, lncRNAs play critical roles in embryonic stem cells. And lincRNAs are most widely studied lncRNAs, however, there might still might exist a large member of uncovered lncRNAs. In this study, we constructed the de novo assembly of transcriptome to detect 6,701 putative long intergenic non coding transcripts (lincRNAs) expressed in mouse embryonic stem cells (ESCs), which might be incomplete with the lack coverage of 5' ends assessed by CAGE peaks. Comparing the TSS proximal regions between the known lincRNAs and their closet protein coding transcripts, our results revealed that the lincRNA TSS proximal regions are associated with the characteristic genomic and epigenetic features. Subsequently, 1,293 lincRNAs were corrected at their 5' ends using the putative lincRNA TSS regions predicted by the TSS proximal region prediction model based on genomic and epigenetic features. Finally, 43 putative lincRNAs were annotated by Gene Ontology terms. In conclusion, this work provides a novel catalog of mouse ESCs-expressed lincRNAs with the relatively complete transcript length, which might be useful for the investigation of transcriptional and post transcriptional regulation of lincRNA in mouse ESCs and even mammalian development. PMID- 27713514 TI - Anti-neuropathic effects of Rosmarinus officinalis L. terpenoid fraction: relevance of nicotinic receptors. AB - Traditional uses and current results highlight the neuroprotective properties of Rosmarinus officinalis L. The compelling need for novel strategies able to relieve neuropathic pain encouraged us to analyze different rosemary leaf extracts in rats following chronic constriction injury (CCI) of sciatic nerve. Ethanol, acetone, and the innovative ultrasound-hexane extractive methods were used to obtain: EE, AE, and for hexane extracts UREprel and URE. Extracts were characterized in terms of typical constituents and repeatedly administered to CCI rats (13-days treatment, from the day of surgery). URE showed the best efficacy and potency in reducing hypersensitivity to noxious- and non-noxious stimuli and spontaneous pain. URE contained the higher quantity of the terpenoid carnosic acid (CA) and its efficacy was compared to pure CA. Histological analysis of the sciatic nerve revealed that URE prevented axon and myelin derangement, edema and inflammatory infiltrate. In the dorsal horn of the spinal cord, URE did not reduce astrocyte activation. Both the pain reliever and the neuroconservative effects of URE were significantly prevented by the nicotinic receptor (nAChR) antagonist mecamylamine. In conclusion, the hexane-ultrasound rosemary extract is able to reduce neuropathic hypersensitivity and protect nervous tissues. Effectiveness is mainly related to the terpenoid fraction by mechanisms involving nAChRs. PMID- 27713515 TI - The influence of single nucleotide polymorphisms on the association between dietary acrylamide intake and endometrial cancer risk. AB - It is unclear whether the association between dietary acrylamide intake and endometrial cancer risk as observed in some epidemiological studies reflects a causal relationship. We aimed at clarifying the causality by analyzing acrylamide gene interactions for endometrial cancer risk. The prospective Netherlands Cohort Study on diet and cancer includes 62,573 women, aged 55-69 years. At baseline, a random subcohort of 2589 women was selected for a case cohort analysis approach. Acrylamide intake of subcohort members and endometrial cancer cases (n = 315) was assessed with a food frequency questionnaire. Single nucleotide polymorphisms (SNPs) in genes in acrylamide metabolism, sex steroid systems, oxidative stress and DNA repair were assessed through a MassARRAY iPLEX Platform. Interaction between acrylamide and SNPs was assessed with Cox proportional hazards analysis, based on 11.3 years of follow-up. Among the results for 57 SNPs and 2 gene deletions, there were no statistically significant interactions after adjustment for multiple testing. However, there were nominally statistically significant interactions for SNPs in acrylamide-metabolizing enzymes: CYP2E1 (rs915906 and rs2480258) and the deletions of GSTM1 and GSTT1. Although in need of confirmation, the interactions between acrylamide intake and CYP2E1 SNPs contribute to the evidence for a causal relationship between acrylamide and endometrial cancer risk. PMID- 27713516 TI - How Humans Solve Complex Problems: The Case of the Knapsack Problem. AB - Life presents us with problems of varying complexity. Yet, complexity is not accounted for in theories of human decision-making. Here we study instances of the knapsack problem, a discrete optimisation problem commonly encountered at all levels of cognition, from attention gating to intellectual discovery. Complexity of this problem is well understood from the perspective of a mechanical device like a computer. We show experimentally that human performance too decreased with complexity as defined in computer science. Defying traditional economic principles, participants spent effort way beyond the point where marginal gain was positive, and economic performance increased with instance difficulty. Human attempts at solving the instances exhibited commonalities with algorithms developed for computers, although biological resource constraints-limited working and episodic memories-had noticeable impact. Consistent with the very nature of the knapsack problem, only a minority of participants found the solution-often quickly-but the ones who did appeared not to realise. Substantial heterogeneity emerged, suggesting why prizes and patents, schemes that incentivise intellectual discovery but discourage information sharing, have been found to be less effective than mechanisms that reveal private information, such as markets. PMID- 27713517 TI - Implementation of Arithmetic and Nonarithmetic Functions on a Label-free and DNA based Platform. AB - A series of complex logic gates were constructed based on graphene oxide and DNA templated silver nanoclusters to perform both arithmetic and nonarithmetic functions. For the purpose of satisfying the requirements of progressive computational complexity and cost-effectiveness, a label-free and universal platform was developed by integration of various functions, including half adder, half subtractor, multiplexer and demultiplexer. The label-free system avoided laborious modification of biomolecules. The designed DNA-based logic gates can be implemented with readout of near-infrared fluorescence, and exhibit great potential applications in the field of bioimaging as well as disease diagnosis. PMID- 27713518 TI - Large gap Quantum Spin Hall Insulators of Hexagonal III-Bi monolayer. AB - In the present work, we demonstrate that both GaBi3 and InBi3 monolayers are Quantum Spin Hall insulators. Here, the electronic band structures and edge states of the two novel monolayers are systematically investigated by first principle calculation. Our analysis of the band inversion and Z2 number demonstrate that both GaBi3 and InBi3 are promising 2D TIs with large gaps of 283meV and 247meV, respectively. Taking GaBi3 as example, it is illustrated that the edge states are impacted by SOC and finite size effect. In addition, it is found that the compression and tension totally affect differently on the edge states. Finally, the electron velocity is studied in detail, which is highly important in the manufacturing of spintronics device. PMID- 27713519 TI - Use of aerosol route to fabricate positively charged Au/Fe3O4 Janus nanoparticles as multifunctional nanoplatforms. AB - Gold (Au)-decorated iron oxide (Fe3O4), Au/Fe3O4, Janus nanoparticles were fabricated via the continuous route for aerosol Au incorporation with Fe3O4 domains synthesized in an aqueous medium as multifunctional nanoplatforms. The fabricated nanoparticles were subsequently exposed to 185-nm UV light to generate positive charges on Au surfaces, and their activities were tested in computed tomography (CT) and magnetic resonance (MR) imaging, gene-delivery and photothermal therapy. No additional polymeric coatings of the Janus particles also had a unique ability to suppress inflammatory responses in macrophages challenged with lipopolysaccharide, which may be due to the absence of amine groups. PMID- 27713520 TI - Identifying molecular signatures of hypoxia adaptation from sex chromosomes: A case for Tibetan Mastiff based on analyses of X chromosome. AB - Genome-wide studies on high-altitude adaptation have received increased attention as a classical case of organismal evolution under extreme environment. However, the current genetic understanding of high-altitude adaptation emanated mainly from autosomal analyses. Only a few earlier genomic studies paid attention to the allosome. In this study, we performed an intensive scan of the X chromosome of public genomic data generated from Tibetan Mastiff (TM) and five other dog populations for indications of high-altitude adaptation. We identified five genes showing signatures of selection on the X chromosome. Notable among these genes was angiomotin (AMOT), which is related to the process of angiogenesis. We sampled additional 11 dog populations (175 individuals in total) at continuous altitudes in China from 300 to 4,000 meters to validate and test the association between the haplotype frequency of AMOT gene and altitude adaptation. The results suggest that AMOT gene may be a notable candidate gene for the adaptation of TM to high-altitude hypoxic conditions. Our study shows that X chromosome deserves consideration in future studies of adaptive evolution. PMID- 27713521 TI - Transcriptome Comparison Analysis of Ostrinia furnacalis in Four Developmental Stages. AB - The Asian corn borer, Ostrinia furnacalis, is one of the most destructive pests of maize and causes huge losses in maize yield each year. In order to characterize the different developmental stages, a high-throughput sequencing platform was employed to perform de novo transcriptome assembly and gene expression analysis for the egg, larva, pupa and adult stages. Approximately 185 million reads were obtained, trimmed, and assembled into 42,638 unigenes with an average length of 801.94 bp and an N50 length of 1,152 bp. These unigene sequences were annotated and classified by performing Gene Ontology (GO), Cluster of Orthologous Groups (KOG) and Kyoto Encyclopedia of Genes and Genomes (KEGG) functional classifications. Comparison of the gene expression profiles of the two transitional stages revealed dramatic differences. Some differentially expressed genes are associated with digestion, cuticularization olfactory recognition and wing formation as well as growth and development. In total, 12 putative insect development-related genes were identified. Real-time quantitative PCR (RT-qPCR) results and sequencing based on relative expression levels of randomly selected genes confirmed these expression patterns. These data represent the most comprehensive transcriptomic resource currently available for O. furnacalis and will facilitate the study of developmental pathways, cuticularization, wing formation and olfactory recognition. PMID- 27713522 TI - Ultrafast spin dynamics and switching via spin transfer torque in antiferromagnets with weak ferromagnetism. AB - The spin-torque driven dynamics of antiferromagnets with Dzyaloshinskii-Moriya interaction (DMI) were investigated based on the Landau-Lifshitz-Gilbert Slonczewski equation with antiferromagnetic and ferromagnetic order parameters (l and m, respectively). We demonstrate that antiferromagnets including DMI can be described by a 2-dimensional pendulum model of l. Because m is coupled with l, together with DMI and exchange energy, close examination of m provides fundamental understanding of its dynamics in linear and nonlinear regimes. Furthermore, we discuss magnetization reversal as a function of DMI and anisotropy energy induced by a spin current pulse. PMID- 27713523 TI - Effects of Melanocortin 3 and 4 Receptor Deficiency on Energy Homeostasis in Rats. AB - Melanocortin-3 and 4 receptors (MC3R and MC4R) can regulate energy homeostasis, but their respective roles especially the functions of MC3R need more exploration. Here Mc3r and Mc4r single and double knockout (DKO) rats were generated using CRISPR-Cas9 system. Metabolic phenotypes were examined and data were compared systematically. Mc3r KO rats displayed hypophagia and decreased body weight, while Mc4r KO and DKO exhibited hyperphagia and increased body weight. All three mutants showed increased white adipose tissue mass and adipocyte size. Interestingly, although Mc3r KO did not show a significant elevation in lipids as seen in Mc4r KO, DKO displayed even higher lipid levels than Mc4r KO. DKO also showed more severe glucose intolerance and hyperglycaemia than Mc4r KO. These data demonstrated MC3R deficiency caused a reduction of food intake and body weight, whereas at the same time exhibited additive effects on top of MC4R deficiency on lipid and glucose metabolism. This is the first phenotypic analysis and systematic comparison of Mc3r KO, Mc4r KO and DKO rats on a homogenous genetic background. These mutant rats will be important in defining the complicated signalling pathways of MC3R and MC4R. Both Mc4r KO and DKO are good models for obesity and diabetes research. PMID- 27713526 TI - NO gas sensing kinetics at room temperature under UV light irradiation of In2O3 nanostructures. AB - In2O3 nanostructure sensors were fabricated by arc-discharging a source composed of a graphite tube containing indium. The NO gas sensing properties, as well as the morphology, structure, and electrical properties, were examined at room temperature under UV light illumination. In particular, the response and recovery kinetics of the sensor at room temperature under various UV light intensities were studied. The maximum response signal was observed at an intermediate UV light intensity, which could be corroborated by a nano-size effect based on the conduction model of a resistive chemical nano sensor. The mechanism for the enhanced adsorption/desorption kinetics for NO in an air environment under UV light irradiation is discussed in detail. Furthermore, the general requirements of the sensor, including the stability, repeatability, and selectivity, are discussed. PMID- 27713525 TI - Behaviors of Microcystis aeruginosa cells during floc storage in drinking water treatment process. AB - This is the first study to systematically investigate the different behaviors of Microcystis aeruginosa in the sludges formed by AlCl3, FeCl3, and polymeric aluminium ferric chloride (PAFC) coagulants during storage. Results show that the viability of Microcystis aeruginosa in PAFC sludge was stronger than that of cells in either AlCl3 or FeCl3 sludge after the same storage time, while the cells' viability in the latter two systems stayed at almost the same level. In AlCl3 and FeCl3 sludges high concentrations of Al and Fe were toxic to Microcystis aeruginosa, whereas in PAFC sludge low levels of Al showed little toxic effect on Microcystis aeruginosa growth and moderate amounts of Fe were beneficial to growth. The lysis of Microcystis aeruginosa in AlCl3 sludge was more serious than that in PAFC sludge, for the same storage time. Although the cell viability in FeCl3 sludge was low (similar to AlCl3 sludge), the Microcystis aeruginosa cells remained basically intact after 10 d storage (similar to PAFC sludge). The maintenance of cellular integrity in FeCl3 sludge might be due to the large floc size and high density, which had a protective effect for Microcystis aeruginosa. PMID- 27713524 TI - GhABF2, a bZIP transcription factor, confers drought and salinity tolerance in cotton (Gossypium hirsutum L.). AB - The bZIP transcription factor (TF) act as an important regulator for the abscisic acid (ABA) mediated abiotic stresses signaling pathways in plants. Here, we reported the cloning and characterization of GhABF2, encoding for typical cotton bZIP TF. Overexpression of GhABF2 significantly improved drought and salt stress tolerance both in Arabidopsis and cotton. However, silencing of GhABF2 made transgenic cotton sensitive to PEG osmotic and salt stress. Expression of GhABF2 was induced by drought and ABA treatments but repressed by high salinity. Transcriptome analysis indicated that GhABF2 increases drought and salt tolerance by regulating genes related to ABA, drought and salt response. The proline contents, activity of superoxide dismutase (SOD) and catalase (CAT) were also significantly increased in GhABF2-overexpression cottons in comparison to wild type after drought and salt treatment. Further, an increase in fiber yield under drought and saline-alkali wetland exhibited the important role of GhABF2 in enhancing the drought and salt tolerance in transgenic lines. In conclusion, manipulation of GhABF2 by biotechnological tools could be a sustainable strategy to deploy drought and salt tolerance in cotton. PMID- 27713527 TI - Thermal and Thermoelectric Transport in Highly Resistive Single Sb2Se3 Nanowires and Nanowire Bundles. AB - In this study, we measured the thermal conductivity and Seebeck coefficient of single Sb2Se3 nanowires and nanowire bundles with a high resistivity (sigma ~ 4.37 * 10-4 S/m). Microdevices consisting of two adjacent suspended silicon nitride membranes were fabricated to measure the thermal transport properties of the nanowires in vacuum. Single Sb2Se3 nanowires with different diameters and nanowire bundles were carefully placed on the device to bridge the two membranes. The relationship of temperature difference on each heating/sensing suspension membranes with joule heating was accurately determined. A single Sb2Se3 nanowire with a diameter of ~ 680 nm was found to have a thermal conductivity (kNW) of 0.037 +/- 0.002 W/m.K. The thermal conductivity of the nanowires is more than an order of magnitude lower than that of bulk materials (k ~ 0.36-1.9 W/m.K) and highly conductive (sigma ~ 3 * 104 S/m) Sb2Se3 single nanowires (k ~ 1 W/m.K). The measured Seebeck coefficient with a positive value of ~ 661 MUV/K is comparable to that of highly conductive Sb2Se3 single nanowires (~ 750 MUV/K). The thermal transport between wires with different diameters and nanowire bundles was compared and discussed. PMID- 27713528 TI - Heat-induced phytohormone changes are associated with disrupted early reproductive development and reduced yield in rice. AB - Heat stress causes morphological and physiological changes and reduces crop yield in rice (Oryza sativa). To investigate changes in phytohormones and their relationships with yield and other attributes under heat stress, four rice varieties (Nagina22, Huanghuazhan, Liangyoupeijiu, and Shanyou 63) were grown in pots and subjected to three high temperature treatments plus control in temperature-controlled greenhouses for 15 d during the early reproductive phase. Yield reductions in Nagina22, Huanghuazhan, and Liangyoupeijiu were attributed to reductions in spikelet fertility, spikelets per panicle, and grain weight. The adverse effects of high temperature were alleviated by application of exogenous 6 benzylaminopurine (6-BA) in the heat-susceptible Liangyoupeijiu. High temperature stress reduced active cytokinins, gibberellin A1 (GA1), and indole-3-acetic acid (IAA), but increased abscisic acid (ABA) and bound cytokinins in young panicles. Correlation analyses and application of exogenous 6-BA revealed that high temperature-induced cytokinin changes may regulate yield components by modulating the differentiation and degradation of branches and spikelets, panicle exsertion, pollen vigor, anther dehiscence, and grain size. Heat-tolerant Shanyou 63 displayed minor changes in phytohormones, panicle formation, and grain yield under high temperature compared with those of the other three varieties. These results suggest that phytohormone changes are closely associated with yield formation, and a small reduction or stability in phytohormone content is required to avoid large yield losses under heat stress. PMID- 27713529 TI - A novel proposal of a simplified bacterial gene set and the neo-construction of a general minimized metabolic network. AB - A minimal gene set (MGS) is critical for the assembly of a minimal artificial cell. We have developed a proposal of simplifying bacterial gene set to approximate a bacterial MGS by the following procedure. First, we base our simplified bacterial gene set (SBGS) on experimentally determined essential genes to ensure that the genes included in the SBGS are critical. Second, we introduced a half-retaining strategy to extract persistent essential genes to ensure stability. Third, we constructed a viable metabolic network to supplement SBGS. The proposed SBGS includes 327 genes and required 431 reactions. This report describes an SBGS that preserves both self-replication and self-maintenance systems. In the minimized metabolic network, we identified five novel hub metabolites and confirmed 20 known hubs. Highly essential genes were found to distribute the connecting metabolites into more reactions. Based on our SBGS, we expanded the pool of targets for designing broad-spectrum antibacterial drugs to reduce pathogen resistance. We also suggested a rough semi-de novo strategy to synthesize an artificial cell, with potential applications in industry. PMID- 27713530 TI - A probabilistic assessment of the likelihood of vegetation drought under varying climate conditions across China. AB - Climate change significantly impacts the vegetation growth and terrestrial ecosystems. Using satellite remote sensing observations, here we focus on investigating vegetation dynamics and the likelihood of vegetation-related drought under varying climate conditions across China. We first compare temporal trends of Normalized Difference Vegetation Index (NDVI) and climatic variables over China. We find that in fact there is no significant change in vegetation over the cold regions where warming is significant. Then, we propose a joint probability model to estimate the likelihood of vegetation-related drought conditioned on different precipitation/temperature scenarios in growing season across China. To the best of our knowledge, this study is the first to examine the vegetation-related drought risk over China from a perspective based on joint probability. Our results demonstrate risk patterns of vegetation-related drought under both low and high precipitation/temperature conditions. We further identify the variations in vegetation-related drought risk under different climate conditions and the sensitivity of drought risk to climate variability. These findings provide insights for decision makers to evaluate drought risk and vegetation-related develop drought mitigation strategies over China in a warming world. The proposed methodology also has a great potential to be applied for vegetation-related drought risk assessment in other regions worldwide. PMID- 27713531 TI - Translation Elongation Factor eEF1A2 is a Novel Anticancer Target for the Marine Natural Product Plitidepsin. AB - eEF1A2 is one of the isoforms of the alpha subunit of the eukaryotic Elongation Factor 1. It is overexpressed in human tumors and is endowed with oncogenic properties, favoring tumor cell proliferation while inhibiting apoptosis. We demonstrate that plitidepsin, an antitumor agent of marine origin that has successfully completed a phase-III clinical trial for multiple myeloma, exerts its antitumor activity by targeting eEF1A2. The drug interacts with eEF1A2 with a KD of 80 nM and a target residence time of circa 9 min. This protein was also identified as capable of binding [14C]-plitidepsin in a cell lysate from K-562 tumor cells. A molecular modelling approach was used to identify a favorable binding site for plitidepsin at the interface between domains 1 and 2 of eEF1A2 in the GTP conformation. Three tumor cell lines selected for at least 100-fold more resistance to plitidepsin than their respective parental cells showed reduced levels of eEF1A2 protein. Ectopic expression of eEF1A2 in resistant cells restored the sensitivity to plitidepsin. FLIM-phasor FRET experiments demonstrated that plitidepsin localizes in tumor cells sufficiently close to eEF1A2 as to suggest the formation of drug-protein complexes in living cells. Altogether, our results strongly suggest that eEF1A2 is the primary target of plitidepsin. PMID- 27713533 TI - Comprehensive mutational analysis of primary and relapse acute promyelocytic leukemia. PMID- 27713532 TI - PB1 as a potential target for increasing the breadth of T-cell mediated immunity to Influenza A. AB - Recently, we showed that combined intranasal and subcutaneous immunization with a non-replicating adenoviral vector expressing NP of influenza A, strain PR8, induced long-standing protection against a range of influenza A viruses. However, H-2b mice challenged with an influenza A strain mutated in the dominant NP366 epitope were not efficiently protected. To address this problem, we envision the use of a cocktail of adenovectors targeting different internal proteins of influenza A virus. Consequently, we investigated the possibility of using PB1 as a target for an adenovector-based vaccine against influenza A. Our results showed that PB1 is not as immunogenic as the NP protein. However, by tethering PB1 to the murine invariant chain we were able to circumvent this problem and raise quite high numbers of PB1-specific CD8+ T cells in the circulation. Nevertheless, mice immunized against PB1 were not as efficiently protected against influenza A challenge as similarly NP-vaccinated animals. The reason for this is not a difference in the quality of the primed cells, nor in functional avidity. However, under similar conditions of immunization fewer PB1-specific cells were recruited to the airways, and surface expression of the dominant PB1 peptide, PB1703, was less stable than in the case of NP366. PMID- 27713534 TI - Moku virus; a new Iflavirus found in wasps, honey bees and Varroa. AB - There is an increasing global trend of emerging infectious diseases (EIDs) affecting a wide range of species, including honey bees. The global epidemic of the single stranded RNA Deformed wing virus (DWV), driven by the spread of Varroa destructor has been well documented. However, DWV is just one of many insect RNA viruses which infect a wide range of hosts. Here we report the full genome sequence of a novel Iflavirus named Moku virus (MV), discovered in the social wasp Vespula pensylvanica collected in Hawaii. The novel genome is 10,056 nucleotides long and encodes a polyprotein of 3050 amino acids. Phylogenetic analysis showed that MV is most closely related to Slow bee paralysis virus (SBPV), which is highly virulent in honey bees but rarely detected. Worryingly, MV sequences were also detected in honey bees and Varroa from the same location, suggesting that MV can also infect other hymenopteran and Acari hosts. PMID- 27713535 TI - The effect of topical atropine on the choroidal thickness of healthy children. AB - The purpose of the current study was to investigate the effect of topical atropine on choroidal thickness using spectral-domain optical coherence tomography. A total of 30 healthy eyes from 30 children were analyzed in this study. A single drop of 1% atropine gel was administered twice daily for a week. Choroidal thickness (CT) was measured using SD-OCT, and changes in CT before and after administration of the eye drops were analyzed at the subfovea and at 1.0-mm intervals (up to 3.0 mm) from the fovea at superior, inferior, nasal, and temporal locations. Pre- and post-cycloplegic axial length (AL) was also measured using the IOLMaster. We observed that administration of 1% atropine gel led to a significant increase in the choroidal thickness under the fovea and at all intervals from the fovea. The greatest change in CT was observed in the inferior meridian, while the nasal meridian exhibited the least change. AL did not significantly differ before and after cycloplegia, and there was no significant correlation between the changes in AL and subfoveal CT. It was concluded that administration of 1% atropine gel can significantly increase CT in the eyes of young Chinese children, albeit with different magnitude at different locations.

AB - Here, we demonstrate a facile approach for the preparation of ZnO nanowires (NWs) with tunable surface wettability that can be manipulated reversibly in a controlled manner from a superhydrophilic state to a superhydrophobic state. The as-synthesized ZnO NWs obtained by a chemical vapor deposition method are superhydrophilic with a contact angle (CA) value of ~0 degrees . After H2 gas annealing at 300 degrees C for 90 minutes, ZnO NWs display superhydrophobic behavior with a roll-off angle less than 5 degrees . However, O2 gas annealing converts these superhydrophobic ZnO NWs into a superhydrophilic state. For switching from superhydrophobic to superhydrophilic state and vice versa in cyclic manner, H2 and O2 gas annealing treatment was used, respectively. A model based on density functional theory indicates that the oxygen-related defects are responsible for CA switching. The water resistant properties of the ZnO NWs coating is found to be durable and can be applied to a variety of substrates including glass, metals, semiconductors, paper and even flexible polymers.

AB - Genetically modified HSV-1 viruses serve as promising vectors for tumour therapy and vaccine development. The CRISPR/Cas9 system is one of the most powerful tools for precise gene editing of the genomes of organisms. However, whether the CRISPR/Cas9 system can precisely and efficiently make gene replacements in the genome of HSV-1 remains essentially unknown. Here, we reported CRISPR/Cas9 mediated editing of the HSV-1 genome in human cells, including the knockout and replacement of large genes. In established cells stably expressing CRISPR/Cas9, gRNA in coordination with Cas9 could direct a precise cleavage within a pre defined target region, and foreign genes were successfully used to replace the target gene seamlessly by HDR-mediated gene replacement. Introducing the NHEJ inhibitor SCR7 to the CRISPR/Cas9 system greatly facilitated HDR-mediated gene replacement in the HSV-1 genome. We provided the first genetic evidence that two copies of the ICP0 gene in different locations on the same HSV-1 genome could be simultaneously modified with high efficiency and with no off-target modifications. We also developed a revolutionized isolation platform for desired recombinant viruses using single-cell sorting. Together, our work provides a significantly improved method for targeted editing of DNA viruses, which will facilitate the development of anti-cancer oncolytic viruses and vaccines.

AB - A geostatistical model to predict human skeletal oxygen isotope values (delta18Op) in Britain is presented here based on a new dataset of Chalcolithic and Early Bronze Age human teeth. The spatial statistics which underpin this model allow the identification of individuals interpreted as 'non-local' to the areas where they were buried (spatial outliers). A marked variation in delta18Op is observed in several areas, including the Stonehenge region, the Peak District, and the Yorkshire Wolds, suggesting a high degree of human mobility. These areas, rich in funerary and ceremonial monuments, may have formed focal points for people, some of whom would have travelled long distances, ultimately being buried there. The dataset and model represent a baseline for future archaeological studies, avoiding the complex conversions from skeletal to water delta18O values a process known to be problematic. PMID- 27713539 TI - Mechanism of high affinity inhibition of the human urate transporter URAT1. AB - Gout is caused by elevated serum urate levels, which can be treated using inhibitors of the uric acid transporter, URAT1. We exploited affinity differences between the human and rat transporters to map inhibitor binding sites in URAT1. Human-rat transporter chimeras revealed that human URAT1 serine-35, phenylalanine 365 and isoleucine-481 are necessary and sufficient to provide up to a 100-fold increase in affinity for inhibitors. Moreover, serine-35 and phenylalanine-365 are important for high-affinity interaction with the substrate urate. A novel URAT1 binding assay provides support for direct interaction with these amino acids; thus, current clinically important URAT1 inhibitors likely bind the same site in URAT1. A structural model suggests that these three URAT1 residues are in close proximity potentially projecting within the channel. Our results indicate that amino acids from several transmembrane segments functionally cooperate to form a high-affinity URAT1 inhibitor binding site that, when occupied, prevents substrate interactions. PMID- 27713540 TI - Polar Superhelices in Ferroelectric Chiral Nanosprings. AB - Topological objects of nontrivial spin or dipolar field textures, such as skyrmions, merons, and vortices, interacting with applied external fields in ferroic materials are of great scientific interest as an intriguing playground of unique physical phenomena and novel technological paradigms. The quest for new topological configurations of such swirling field textures has primarily been done for magnets with Dzyaloshinskii-Moriya interactions, while the absence of such intrinsic chiral interactions among electric dipoles left ferroelectrics aside in this quest. Here, we demonstrate that a helical polarization coiled into another helix, namely a polar superhelix, can be extrinsically stabilized in ferroelectric nanosprings. The interplay between dipolar interactions confined in the chiral geometry and the complex strain field of mixed bending and twisting induces the superhelical configuration of electric polarization. The geometrical structure of the polar superhelix gives rise to electric chiralities at two different length scales and the coexistence of three order parameters, i.e., polarization, toroidization, and hypertoroidization, both of which can be manipulated by homogeneous electric and/or mechanical fields. Our work therefore provides a new geometrical configuration of swirling dipolar fields, which offers the possibility of multiple order-parameters, and electromechanically controllable dipolar chiralities and associated electro-optical responses. PMID- 27713541 TI - Femtosecond dynamics of energetic electrons in high intensity laser-matter interactions. AB - Highly energetic electrons are generated at the early phases of the interaction of short-pulse high-intensity lasers with solid targets. These escaping particles are identified as the essential core of picosecond-scale phenomena such as laser based acceleration, surface manipulation, generation of intense magnetic fields and electromagnetic pulses. Increasing the number of the escaping electrons facilitate the late time processes in all cases. Up to now only indirect evidences of these important forerunners have been recorded, thus no detailed study of the governing mechanisms was possible. Here we report, for the first time, direct time-dependent measurements of energetic electrons ejected from solid targets by the interaction with a short-pulse high-intensity laser. We measured electron bunches up to 7 nanocoulombs charge, picosecond duration and 12 megaelectronvolts energy. Our 'snapshots' capture their evolution with an unprecedented temporal resolution, demonstrat- ing a significant boost in charge and energy of escaping electrons when increasing the geometrical target curvature. These results pave the way toward significant improvement in laser acceleration of ions using shaped targets allowing the future development of small scale laser-ion accelerators. PMID- 27713542 TI - Electrostatic repulsive out-of-plane actuator using conductive substrate. AB - A pseudo-three-layer electrostatic repulsive out-of-plane actuator is proposed. It combines the advantages of two-layer and three-layer repulsive actuators, i.e., fabrication requirements and fill factor. A theoretical model for the proposed actuator is developed and solved through the numerical calculation of Schwarz-Christoffel mapping. Theoretical and simulated results show that the pseudo-three-layer actuator offers higher performance than the two-layer and three-layer actuators with regard to the two most important characteristics of actuators, namely, driving force and theoretical stroke. Given that the pseudo three-layer actuator structure is compatible with both the parallel-plate actuators and these two types of repulsive actuators, a 19-element two-layer repulsive actuated deformable mirror is operated in pseudo-three-layer electrical connection mode. Theoretical and experimental results demonstrate that the pseudo three-layer mode produces a larger displacement of 0-4.5 MUm for a dc driving voltage of 0-100 V, when compared with that in two-layer mode.

PMID- 27713544 TI - AML1/ETO accelerates cell migration and impairs cell-to-cell adhesion and homing of hematopoietic stem/progenitor cells. AB - The AML1/ETO fusion protein found in acute myeloid leukemias functions as a transcriptional regulator by recruiting co-repressor complexes to its DNA binding site. In order to extend the understanding of its role in preleukemia, we expressed AML1/ETO in a murine immortalized pluripotent hematopoietic stem/progenitor cell line, EML C1, and found that genes involved in functions such as cell-to-cell adhesion and cell motility were among the most significantly regulated as determined by RNA sequencing. In functional assays, AML1/ETO expressing cells showed a decrease in adhesion to stromal cells, an increase of cell migration rate in vitro, and displayed an impairment in homing and engraftment in vivo upon transplantation into recipient mice. Our results suggest that AML1/ETO expression determines a more mobile and less adherent phenotype in preleukemic cells, therefore altering the interaction with the hematopoietic niche, potentially leading to the migration across the bone marrow barrier and to disease progression. PMID- 27713545 TI - Fully inkjet-printed microfluidics: a solution to low-cost rapid three dimensional microfluidics fabrication with numerous electrical and sensing applications. AB - As the needs for low-cost rapidly-produced microfluidics are growing with the trend of Lab-on-a-Chip and distributed healthcare, the fully inkjet-printing of microfluidics can be a solution to it with numerous potential electrical and sensing applications. Inkjet-printing is an additive manufacturing technique featuring no material waste and a low equipment cost. Moreover, similar to other additive manufacturing techniques, inkjet-printing is easy to learn and has a high fabrication speed, while it offers generally a great planar resolution down to below 20 um and enables flexible designs due to its inherent thin film deposition capabilities. Due to the thin film feature, the printed objects also usually obtain a high vertical resolution (such as 4.6 um). This paper introduces a low-cost rapid three-dimensional fabrication process of microfluidics, that relies entirely on an inkjet-printer based single platform and can be implemented directly on top of virtually any substrates. PMID- 27713546 TI - Testing multi-scale processing in the auditory system. AB - Natural sounds contain information on multiple timescales, so the auditory system must analyze and integrate acoustic information on those different scales to extract behaviorally relevant information. However, this multi-scale process in the auditory system is not widely investigated in the literature, and existing models of temporal integration are mainly built upon detection or recognition tasks on a single timescale. Here we use a paradigm requiring processing on relatively 'local' and 'global' scales and provide evidence suggesting that the auditory system extracts fine-detail acoustic information using short temporal windows and uses long temporal windows to abstract global acoustic patterns. Behavioral task performance that requires processing fine-detail information does not improve with longer stimulus length, contrary to predictions of previous temporal integration models such as the multiple-looks and the spectro-temporal excitation pattern model. Moreover, the perceptual construction of putatively 'unitary' auditory events requires more than hundreds of milliseconds. These findings support the hypothesis of a dual-scale processing likely implemented in the auditory cortex. PMID- 27713547 TI - Hierarchical Micro/Nano-Porous Acupuncture Needles Offering Enhanced Therapeutic Properties. AB - Acupuncture as a therapeutic intervention has been widely used for treatment of many pathophysiological disorders. For achieving improved therapeutic effects, relatively thick acupuncture needles have been frequently used in clinical practice with, in turn, enhanced stimulation intensity. However due to the discomforting nature of the larger-diameter acupuncture needles there is considerable interest in developing advanced acupuncture therapeutical techniques that provide more comfort with improved efficacy. So motivated, we have developed a new class of acupuncture needles, porous acupuncture needles (PANs) with hierarchical micro/nano-scale conical pores upon the surface, fabricated via a simple and well known electrochemical process, with surface area approximately 20 times greater than conventional acupuncture needles. The performance of these high-surface-area PANs is evaluated by monitoring the electrophysiological and behavioral responses from the in vivo stimulation of Shenmen (HT7) points in Wistar rats, showing PANs to be more effective in controlling electrophysiological and behavioral responses than conventional acupuncture needles. Comparative analysis of cocaine induced locomotor activity using PANs and thick acupuncture needles shows enhanced performance of PANs with significantly less pain sensation. Our work offers a unique pathway for achieving a comfortable and improved acupuncture therapeutic effect. PMID- 27713548 TI - Intra-islet lesions and lobular variations in beta-cell mass expansion in ob/ob mice revealed by 3D imaging of intact pancreas. AB - The leptin deficient ob/ob mouse is a widely used model for studies on initial aspects of metabolic disturbances leading to type 2 diabetes, including insulin resistance and obesity. Although it is generally accepted that ob/ob mice display a dramatic increase in beta-cell mass to compensate for increased insulin demand, the spatial and quantitative dynamics of beta-cell mass distribution in this model has not been assessed by modern optical 3D imaging techniques. We applied optical projection tomography and ultramicroscopy imaging to extract information about individual islet beta-cell volumes throughout the volume of ob/ob pancreas between 4 and 52 weeks of age. Our data show that cystic lesions constitute a significant volume of the hyperplastic ob/ob islets. We propose that these lesions are formed by a mechanism involving extravasation of red blood cells/plasma due to increased islet vessel blood flow and vessel instability. Further, our data indicate that the primary lobular compartments of the ob/ob pancreas have different potentials for expanding their beta-cell population. Unawareness of the characteristics of beta-cell expansion in ob/ob mice presented in this report may significantly influence ex vivo and in vivo assessments of this model in studies of beta-cell adaptation and function. PMID- 27713549 TI - A study of the temporal robustness of the growing global container-shipping network. AB - Whether they thrive as they grow must be determined for all constantly expanding networks. However, few studies have focused on this important network feature or the development of quantitative analytical methods. Given the formation and growth of the global container-shipping network, we proposed the concept of network temporal robustness and quantitative method. As an example, we collected container liner companies' data at two time points (2004 and 2014) and built a shipping network with ports as nodes and routes as links. We thus obtained a quantitative value of the temporal robustness. The temporal robustness is a significant network property because, for the first time, we can clearly recognize that the shipping network has become more vulnerable to damage over the last decade: When the node failure scale reached 50% of the entire network, the temporal robustness was approximately -0.51% for random errors and -12.63% for intentional attacks. The proposed concept and analytical method described in this paper are significant for other network studies. PMID- 27713550 TI - Chromatic Mechanical Response in 2-D Layered Transition Metal Dichalcogenide (TMDs) based Nanocomposites. AB - The ability to convert photons of different wavelengths directly into mechanical motion is of significant interest in many energy conversion and reconfigurable technologies. Here, using few layer 2H-MoS2 nanosheets, layer by layer process of nanocomposite fabrication, and strain engineering, we demonstrate a reversible and chromatic mechanical response in MoS2-nanocomposites between 405 nm to 808 nm with large stress release. The chromatic mechanical response originates from the d orbitals and is related to the strength of the direct exciton resonance A and B of the few layer 2H-MoS2 affecting optical absorption and subsequent mechanical response of the nanocomposite. Applying uniaxial tensile strains to the semiconducting few-layer 2H-MoS2 crystals in the nanocomposite resulted in spatially varying energy levels inside the nanocomposite that enhanced the broadband optical absorption up to 2.3 eV and subsequent mechanical response. The unique photomechanical response in 2H-MoS2 based nanocomposites is a result of the rich d electron physics not available to nanocomposites based on sp bonded graphene and carbon nanotubes, as well as nanocomposite based on metallic nanoparticles. The reversible strain dependent optical absorption suggest applications in broad range of energy conversion technologies that is not achievable using conventional thin film semiconductors. PMID- 27713551 TI - Pomegranate extract decreases oxidative stress and alleviates mitochondrial impairment by activating AMPK-Nrf2 in hypothalamic paraventricular nucleus of spontaneously hypertensive rats. AB - High blood pressure, or "hypertension," is associated with high levels of oxidative stress in the paraventricular nucleus of the hypothalamus. While pomegranate extract is a known antioxidant that is thought to have antihypertensive effects, the mechanism whereby pomegranate extract lowers blood pressure and the tissue that mediates its antihypertensive effects are currently unknown. We have used a spontaneously hypertensive rat model to investigate the antihypertensive properties of pomegranate extract. We found that chronic treatment of hypertensive rats with pomegranate extract significantly reduced blood pressure and cardiac hypertrophy. Furthermore, pomegranate extract reduced oxidative stress, increased the antioxidant defense system, and decreased inflammation in the paraventricular nucleus of hypertensive rats. We determined that pomegranate extract reduced mitochondrial superoxide anion levels and increased mitochondrial function in the paraventricular nucleus of hypertensive rats by promoting mitochondrial biogenesis and improving mitochondrial dynamics and clearance. We went on to identify the AMPK-nuclear factor-erythroid 2 p45 related factor 2 (Nrf2) pathway as a mechanism whereby pomegranate extract reduces oxidative stress in the paraventricular nucleus to relieve hypertension. Our findings demonstrate that pomegranate extract alleviates hypertension by reducing oxidative stress and improving mitochondrial function in the paraventricular nucleus, and reveal multiple novel targets for therapeutic treatment of hypertension.

AB - The unprecedented outbreak of Ebola in West Africa resulted in over 28,000 cases and 11,000 deaths, underlining the need for a better understanding of the biology of this highly pathogenic virus to develop specific counter strategies. Two filoviruses, the Ebola and Marburg viruses, result in a severe and often fatal infection in humans. However, bats are natural hosts and survive filovirus infections without obvious symptoms. The molecular basis of this striking difference in the response to filovirus infections is not well understood. We report a systematic overview of differentially expressed genes, activity motifs and pathways in human and bat cells infected with the Ebola and Marburg viruses, and we demonstrate that the replication of filoviruses is more rapid in human cells than in bat cells. We also found that the most strongly regulated genes upon filovirus infection are chemokine ligands and transcription factors. We observed a strong induction of the JAK/STAT pathway, of several genes encoding inhibitors of MAP kinases (DUSP genes) and of PPP1R15A, which is involved in ER stress-induced cell death. We used comparative transcriptomics to provide a data resource that can be used to identify cellular responses that might allow bats to survive filovirus infections. PMID- 27713556 TI - Non-equilibrium quantum phase transition via entanglement decoherence dynamics. AB - We investigate the decoherence dynamics of continuous variable entanglement as the system-environment coupling strength varies from the weak-coupling to the strong-coupling regimes. Due to the existence of localized modes in the strong coupling regime, the system cannot approach equilibrium with its environment, which induces a nonequilibrium quantum phase transition. We analytically solve the entanglement decoherence dynamics for an arbitrary spectral density. The nonequilibrium quantum phase transition is demonstrated as the system-environment coupling strength varies for all the Ohmic-type spectral densities. The 3-D entanglement quantum phase diagram is obtained. PMID- 27713554 TI - Glibenclamide impairs responses of neutrophils against Burkholderia pseudomallei by reduction of intracellular glutathione. AB - The major risk factor for melioidosis, an infectious disease caused by B. pseudomallei, is diabetes mellitus. More than half of diabetic melioidosis patients in Thailand were prescribed glibenclamide. Recent evidence demonstrates that glibenclamide reduces pro-inflammatory cytokine production by polymorphonuclear neutrophils (PMNs) of diabetic individuals in response to this bacterial infection. However, the mechanisms by which glibenclamide affects cytokine production are unknown. We found that PMNs from glibenclamide-treated diabetic individuals infected with live B. pseudomallei in vitro showed lower free glutathione (GSH) levels compared with those of healthy individuals. Glibenclamide decreased GSH levels and glutathione peroxidase (GPx) of PMNs after exposed to live B. pseudomallei. Moreover, glibenclamide reduced cytokine production and migration capacity of infected PMNs, whereas GSH could restore these functions. Taken together, our data show a link between the effect of glibenclamide on GSH and PMN functions in response to B. pseudomallei that may contribute to the susceptibility of diabetic individuals to B. pseudomallei infection. PMID- 27713557 TI - Olfactory experiences dynamically regulate plasticity of dendritic spines in granule cells of Xenopus tadpoles in vivo. AB - Granule cells, rich in dendrites with densely punctated dendritic spines, are the most abundant inhibitory interneurons in the olfactory bulb. The dendritic spines of granule cells undergo remodeling during the development of the nervous system. The morphological plasticity of the spines' response to different olfactory experiences in vivo is not fully known. In initial studies, a single granule cell in Xenopus tadpoles was labeled with GFP plasmids via cell electroporation; then, morphologic changes of the granule cell spines were visualized by in vivo confocal time-lapse imaging. With the help of long-term imaging, the total spine density, dynamics, and stability of four types of dendritic spines (mushroom, stubby, thin and filopodia) were obtained. Morphological analysis demonstrated that odor enrichment produced a remarkable increase in the spine density and stability of large mushroom spine. Then, with the help of short-term imaging, we analyzed the morphological transitions among different spines. We found that transitions between small spines (thin and filopodia) were more easily influenced by odor stimulation or olfactory deprivation. These results indicate that different olfactory experiences can regulate the morphological plasticity of different dendritic spines in the granule cell. PMID- 27713555 TI - Lipid metabolism is associated with developmental epigenetic programming. AB - Maternal diet and metabolism impact fetal development. Epigenetic reprogramming facilitates fetal adaptation to these in utero cues. To determine if maternal metabolite levels impact infant DNA methylation globally and at growth and development genes, we followed a clinical birth cohort of 40 mother-infant dyads. Targeted metabolomics and quantitative DNA methylation were analyzed in 1st trimester maternal plasma (M1) and delivery maternal plasma (M2) as well as infant umbilical cord blood plasma (CB). We found very long chain fatty acids, medium chain acylcarnitines, and histidine were: (1) stable in maternal plasma from pregnancy to delivery, (2) significantly correlated between M1, M2, and CB, and (3) in the top 10% of maternal metabolites correlating with infant DNA methylation, suggesting maternal metabolites associated with infant DNA methylation are tightly controlled. Global DNA methylation was highly correlated across M1, M2, and CB. Thus, circulating maternal lipids are associated with developmental epigenetic programming, which in turn may impact lifelong health and disease risk. Further studies are required to determine the causal link between maternal plasma lipids and infant DNA methylation patterns. PMID- 27713558 TI - Occurrence and preliminarily environmental risk assessment of selected pharmaceuticals in the urban rivers, China. AB - Twelve selected pharmaceuticals including antibiotics, analgesics, antiepileptics and lipid regulators were analysed and detected in water samples collected from 18 sampling sections along the three main urban rivers in Yangpu District of Shanghai, China during four sampling campaigns. Besides, algal growth inhibition test was conducted to preliminarily assess the eco-toxicology induced by the target pharmaceuticals in the rivers. Mean levels for most of target compounds were generally below 100 ng/L at sampling sections, with the exception of caffeine and paracetamol presenting considerably high concentration. The detected pharmaceuticals in the urban rivers ranged from .05) with both groups displaying equal outcomes. Two studies measured an IASTM intervention versus a control or alternate intervention group on the effects of joint ROM. The IASTM intervention produced significant (P<.05) short term gains up to 24 hours. CONCLUSION: The literature measuring the effects of IASTM is still emerging. The current research has indicated insignificant results which challenges the efficacy of IASTM as a treatment for common musculoskeletal pathology, which may be due to the methodological variability among studies. There appears to be some evidence supporting its ability to increase short term joint ROM. PMID- 27713577 TI - A narrative review of new trends in the diagnosis of myofascial trigger points: diagnostic ultrasound imaging and biomarkers. AB - Myofascial pain syndrome (MPS) is one of the most common conditions of chronic musculoskeletal pain encountered by primary healthcare practitioners on a daily basis. It is generally accepted amongst the broad profile of healthcare practitioners treating MPS that the presence of discrete, palpable and tender nodules within the muscle, known as myofascial trigger points (MTrP), is necessary to confirm the diagnosis of MPS. Manual palpation is currently the most common technique used to detect MTrP, however, previous research has shown that the reliability of manual palpation for detecting MTrP is poor, and in our opinion unacceptably poor, leading to inconsistent diagnosis of MPS and poor patient outcomes. There are currently no objective accepted diagnostic criteria for the clinical detection of MTrP, nor are there standardized diagnostic criteria for MPS. Two promising areas of research with potential for enhancing the diagnosis of MPS include the use of diagnostic ultrasound and biomarkers. Further research is needed to advance the development of composite diagnostic criteria employing ultrasound imaging, biomarker assessments and physical assessment to enhance the accuracy and objectivity of MTrP detection and diagnosis of chronic MPS disorder. PMID- 27713576 TI - Neck pain in children: a retrospective case series. AB - INTRODUCTION: Spinal pain in the paediatric population is a significant health issue, with an increasing prevalence as they age. Paediatric patients attend for chiropractor care for spinal pain, yet, there is a paucity of quality evidence to guide the practitioner with respect to appropriate care planning. METHODS: A retrospective chart review was used to describe chiropractic management of paediatric neck pain. Two researchers abstracted data from 50 clinical files that met inclusion criteria from a general practice chiropractic office in the Greater Toronto Area, Canada. Data were entered into SPSS 15 and descriptively analyzed. RESULTS: Fifty paediatric neck pain patient files were analysed. Patients' age ranged between 6 and 18 years (mean 13 years). Most (98%) were diagnosed with Grade I-II mechanical neck pain. Treatment frequency averaged 5 visits over 19 days; with spinal manipulative therapy used in 96% of patients. Significant improvement was recorded in 96% of the files. No adverse events were documented. CONCLUSION: Paediatric mechanical neck pain appears to be successfully managed by chiropractic care. Spinal manipulative therapy appears to benefit paediatric mechanical neck pain resulting from day-today activities with no reported serious adverse events. Results can be used to inform clinical trials assessing effectiveness of manual therapy in managing paediatric mechanical neck pain. PMID- 27713578 TI - A rare cause of chronic elbow pain in an adolescent baseball player: a case report. AB - OBJECTIVE: To present a case of chronic elbow pain as a result of a hidden underlying osteochondral defect. CLINICAL FEATURES: A 17-year old baseball player presented with chronic lateral elbow pain. Examination revealed swelling of the elbow with signs of possible ligament, muscle, and tendon injury. DIAGNOSIS AND TREATMENT: Although there was apparent soft-tissue injury, the elbow swelling created immediate suspicion of a more serious underlying condition. Examination revealed a swollen and tender elbow, with plain x-ray confirming a subchondral bone disorder (osteochondral defect) of the capitellum. Surgical repair was performed by an orthopedic surgeon using DeNovo NT Natural Tissue Grafts: the implantation of small pieces of juvenile joint cartilage into the affected area, using glue-like fibrin. Rehabilitation of the elbow began immediately following surgery. SUMMARY: Examination and imaging indicated that elbow pain in an adolescent baseball player could be from multiple sources, however, the chronic swelling raised suspicion of a condition requiring immediate and further investigation. PMID- 27713579 TI - Differences in hip range of motion among collegiate pitchers when compared to youth and professional baseball pitcher data. AB - The purpose of this study was to measure passive hip internal (IR) and external rotation (ER) range of motion (ROM) in collegiate baseball pitchers and compare to published youth and professional values. Measures were taken on the bilateral hips of 29 participants (mean age 20.0+/-1.4, range 18-22 years). Results identified no significant differences between the stance and stride hip in collegiate right handed pitchers for IR (p= 0.22, ES 0.23) and ER (p=.08, ES= 0.25). There was no significant difference in left handed pitchers for IR (p= 0.80, ES= 0.11) and ER (p= 0.56, ES= 0.15). When comparing youth to collegiate, IR increased in the stance (2o) and stride (5o) hip and an increase in the stance (5o) and stride (5o) hip were present for ER as well. From collegiate to professional, IR increased in the stance (4o) and stride (3o) hip whereas a decrease in the stance (9o) and stride (12o) hip was present for ER. The data suggests an increase in passive ROM from youth to collegiate and a decrease from collegiate to professional. Understanding passive hip ROM values among the different levels of pitchers may assist clinicians in developing time dependent interventions to prevent future injury and enhance performance. PMID- 27713580 TI - The meaning of it all: evaluating knowledge of Minimal Clinically Important Difference (MCID) among chiropractic students. AB - INTRODUCTION: Patient-reported outcome measures are frequently used to monitor patient progress during chiropractic care, yet student interns utilizing such assessments are unfamiliar with what magnitude of change (MCID) is considered beneficial to the patient. OBJECTIVE: This work seeks to determine chiropractic intern knowledge of MCID. METHODS: A five-item survey was administered to 104 chiropractic student interns. RESULTS: Nearly one-third of the interns correctly defined the MCID acronym, and approximately one-third of the interns knew at least one MCID value for the outcome assessments in the EHR. Surprisingly, 20% of the interns reported knowledge of at least one MCID value, but answered incorrectly pertaining to the MCID acronym. CONCLUSION: Student interns value patient perception, but have limited knowledge of MCID values. Addressing this gap will improve their understanding of patient progress and inform their treatment decisions both in the outpatient clinic and in their practices following graduation.

AB - BACKGROUND: Musculoskeletal injuries stemming from forceful muscular contractions during seizures have been documented in the literature. Reports of multiple seizure-induced spinal fractures, in the absence of external trauma and without risk factors for fracture, are rare. CASE PRESENTATION: A 28-year-old male, newly diagnosed with epilepsy, presented to a chiropractic clinic with the complaint of mid-thoracic pain beginning after a tonic-clonic seizure with no associated external trauma. Radiographs revealed the impression of five new vertebral compression fractures from T4 to T8. DISCUSSION: This report highlights the importance of a complete history and examination of patients with a history of tonic-clonic seizures and back pain, especially when considering spinal adjustments. SUMMARY: This case report presents an argument that a tonic-clonic seizure, in the absence of external trauma or significant risk factors for fracture, resulted in multiple vertebral compression fractures.

AB - Novel techniques that enable reagent free detection and analysis of single cells are of great interest for the development of biological and medical sciences as well as point-of-care health service technologies. Highly sensitive and broadband radio-frequency (RF) sensors are promising candidates for such a technique. In this work, we present a highly sensitive and tunable RF sensor, which is based on interference processes and built with a 100 nm slotline structure. The highly concentrated RF fields, up to ~1.76*107 V/m, enable strong interactions between Giant unilamellar vesicles (GUVs) and fields for high sensitivity operations. We also provide two modeling approaches to extract cell dielectric properties from measured scattering parameters. GUVs of different molecular compositions are synthesized and analyzed with the RF sensor at ~2 GHz, ~2.5 GHz, and ~2.8 GHz with an initial |S21 | min of ~-100 dB. Corresponding GUV dielectric properties are obtained. A one-dimensional scanning of single GUV is also demonstrated. PMID- 27713586 TI - ?Educacion o desintegracion? Parental migration, remittances and left-behind children's education in western Guatemala. AB - A growing body of literature addresses the positive impacts of international migration and remittances on children's education. This paper offers a nuanced, qualitative view that addresses the positive remittance-related benefits to children's education and the negative repercussions of parental absences on children's relationships with schooling from the perspectives of parents and local educators. A case study approach including field interviews of parents, teachers and school administrators from five western Guatemalan communities was used. Findings suggest that remittances improve basic living conditions, allowing many children to access a more comfortable and substantive education. However, parental absences can disrupt the educational opportunities for others. PMID- 27713587 TI - Priming effect of benthic gastropod mucus on sedimentary organic matter remineralization. AB - Mucous gels are produced by benthic animals rapidly and in copious amounts, and consequently they are a possible priming substrate whose addition in modest amounts may affect sedimentary organic matter (SOM) remineralization. The priming effect of benthic infaunal mucus was tested using mucus of the common gastropod Neverita duplicata as model substrate. Its composition is typical of marine molluscan mucus, consisting primarily of water (>96% by weight). Salt-free dry weight constitutes 0.7% of total mucus. Relationships between C, N and S content show the presence of N-free and S-free fractions, indicative of mucopolysaccharides, that account for approximately half of the total C present. The C/N ratios of the N-containing fraction (6.1 and 8.75 for pedal and hypobranchial mucus, respectively) are indicative of a carbohydrate-protein complex. Relatively low C/S ratios for the S-containing fraction (21.8 and 10.5 for pedal and hypobranchial mucus, respectively) and positive staining with Alcian Blue dye are indicative of S-ester and alkyl-SO42- groups bridging mucopolysaccharide and glycoprotein components. Anaerobic incubations of pedal mucus, sediment and mucus-sediment mixture resulted in the generation of SigmaCO2 and NH4+ at ratios lower than substrate C/N ratios, indicating the preferential decomposition of N-rich components. Production rates of SigmaCO2 and NH4+ in mucus-sediment incubations are higher, by 9+/-16% and 29+/-11%, respectively, than those predicted from linear addition of mucus-only and sediment-only rates. The accelerated remineralization rate of N in the presence of modest mucus contribution suggests that benthic mucus addition can affect SOM remineralization processes through a "priming" effect.

AB - Investigation of titanium-centered metallacycle-mediated cross-coupling between unsymmetrical internal alkynes has led to the discovery that TMSCl significantly accelerates the C-C bond forming event. We report a collection of results that compare the efficiency of this reaction employing Ti(Oi-Pr)4/2n-BuLi in PhMe with and without TMSCl, demonstrating in every case that the presence of TMSCl has a profound impact on efficiency. While relevant in the context of developing this fundamental bond-forming process as an entry to more complex organometallic transformations, these modified reaction conditions allow coupling processes to be run at > 10 times the concentrations previously possible [in 2.4M n-BuLi (hexanes)], without the requirement of additional solvent. Finally, we demonstrate the effectiveness of these modified reaction conditions for the annulative cross-coupling between TMS-alkynes and 1,6-enynes leading to the formation of angularly substituted hydrindanes with, now well appreciated, high levels of regio- and stereoselection. PMID- 27713590 TI - Spatio-Temporal EEG Models for Brain Interfaces. AB - Multichannel electroencephalography (EEG) is widely used in non-invasive brain computer interfaces (BCIs) for user intent inference. EEG can be assumed to be a Gaussian process with unknown mean and autocovariance, and the estimation of parameters is required for BCI inference. However, the relatively high dimensionality of the EEG feature vectors with respect to the number of labeled observations lead to rank deficient covariance matrix estimates. In this manuscript, to overcome ill-conditioned covariance estimation, we propose a structure for the covariance matrices of the multichannel EEG signals. Specifically, we assume that these covariances can be modeled as a Kronecker product of temporal and spatial covariances. Our results over the experimental data collected from the users of a letter-by-letter typing BCI show that with less number of parameter estimations, the system can achieve higher classification accuracies compared to a method that uses full unstructured covariance estimation. Moreover, in order to illustrate that the proposed Kronecker product structure could enable shortening the BCI calibration data collection sessions, using Cramer-Rao bound analysis on simulated data, we demonstrate that a model with structured covariance matrices will achieve the same estimation error as a model with no covariance structure using fewer labeled EEG observations.

AB - We describe a convergent synthesis of a bryostatin analogue in which the natural A- and B-ring pyrans have been replaced by phenyl rings. The new analogue exhibited PMA like behavior in cell assays, but failed to maintain high affinity binding for PKC, despite retaining an unaltered C-ring 'binding domain'. PMID- 27713591 TI - Inter- and intra-specific variation in drought sensitivity in Abies spec. and its relation to wood density and growth traits. AB - Understanding drought sensitivity of tree species and its intra-specific variation is required to estimate the effects of climate change on forest productivity, carbon sequestration and tree mortality as well as to develop adaptive forest management measures. Here, we studied the variation of drought reaction of six European Abies species and ten provenances of Abies alba planted in the drought prone eastern Austria. Tree-ring and X-ray densitometry data were used to generate early- and latewood measures for ring width and wood density. Moreover, the drought reaction of species and provenances within six distinct drought events between 1970 and 2011, as identified by the standardized precipitation index, was determined by four drought response measures. The mean reaction of species and provenances to drought events was strongly affected by the seasonal occurrence of the drought: a short, strong drought at the beginning of the growing season resulted in growth reductions up to 50%, while droughts at the end of the growing season did not affect annual increment. Wood properties and drought response measures showed significant variation among Abies species as well as among A. alba provenances. Whereas A. alba provenances explained significant parts in the variation of ring width measures, the Abies species explained significant parts in the variation of wood density parameters. A consistent pattern in drought response across the six drought events was observed only at the inter-specific level, where A. nordmanniana showed the highest resistance and A. cephalonica showed the best recovery after drought. In contrast, differences in drought reaction among provenances were only found for the milder drought events in 1986, 1990, 1993 and 2000 and the ranking of provenances varied at each drought event. This indicates that genetic variation in drought response within A. alba is more limited than among Abies species. Low correlations between wood density parameters and drought response measures suggest that wood density is a poor predictor of drought sensitivity in Abies spec.

AB - Polyether ether ketone (PEEK) rods were coated via ion beam asssited deposition (IBAD) at room temperature. The coating consists of a two-layer design of yttria stabilized zirconia (YSZ) as a heat-protection layer, and hydroxyapatite (HA) as a top layer to increase bioactivity. A rotating substrate holder was designed to deposit an even coating on the cylindrical surface of PEEK rods; the uniformity is verified by cross-sectional measurements using scanning electron microscopy (SEM). Deposition is followed by heat treatment of the coating using microwave annealing and autoclaving. Transmission electron microscopy (TEM) showed a dense, uniform columnar grain structure in the YSZ layer that is well bonded to the PEEK substrate, while the calcium phosphate layer was amorphous and pore-free in its as-deposited state. Subsequent heat treatment via microwave energy introduced HA crystallization in the calcium phosphate layer and additional autoclaving further expanded the crystallization of the HA layer. Chemical composition evaluation of the coating indicated the Ca/P ratios of the HA layer to be near that of stoichiometric HA, with minor variations through the HA layer thickness. The adhesion strength of as-deposited HA/YSZ coatings on smooth, polished PEEK surfaces was mostly unaffected by microwave heat treatment, but decreased with additional autoclave treatment. Increasing surface roughness showed improvement of bond strength. PMID- 27713593 TI - Multiple Imputation of a Randomly Censored Covariate Improves Logistic Regression Analysis. AB - Randomly censored covariates arise frequently in epidemiologic studies. The most commonly used methods, including complete case and single imputation or substitution, suffer from inefficiency and bias. They make strong parametric assumptions or they consider limit of detection censoring only. We employ multiple imputation, in conjunction with semi-parametric modeling of the censored covariate, to overcome these shortcomings and to facilitate robust estimation. We develop a multiple imputation approach for randomly censored covariates within the framework of a logistic regression model. We use the non-parametric estimate of the covariate distribution or the semiparametric Cox model estimate in the presence of additional covariates in the model. We evaluate this procedure in simulations, and compare its operating characteristics to those from the complete case analysis and a survival regression approach. We apply the procedures to an Alzheimer's study of the association between amyloid positivity and maternal age of onset of dementia. Multiple imputation achieves lower standard errors and higher power than the complete case approach under heavy and moderate censoring and is comparable under light censoring. The survival regression approach achieves the highest power among all procedures, but does not produce interpretable estimates of association. Multiple imputation offers a favorable alternative to complete case analysis and ad hoc substitution methods in the presence of randomly censored covariates within the framework of logistic regression. PMID- 27713594 TI - Environmental Perceptions and Health before and after Relocation to a Green Building. AB - Green buildings are designed to have low environmental impacts and improved occupant health and well-being. Improvements to the built environment including ventilation, lighting, and materials have resulted in improved indoor environmental quality (IEQ) in green buildings, but the evidence around occupant health is currently centered around environmental perceptions and self-reported health. To investigate the objective impact of green buildings on health, we tracked IEQ, self-reported health, and heart rate in 30 participants from green and conventional buildings for two weeks. 24 participants were then selected to be relocated to the Syracuse Center of Excellence, a LEED platinum building, for six workdays. While they were there, ventilation, CO2, and volatile organic compound (VOC) levels were changed on different days to match the IEQ of conventional, green, and green+ (green with increased ventilation) buildings. Participants reported improved air quality, odors, thermal comfort, ergonomics, noise and lighting and fewer health symptoms in green buildings prior to relocation. After relocation, participants consistently reported fewer symptoms during the green building conditions compared to the conventional one, yet symptom counts were more closely associated with environmental perceptions than with measured IEQ. On average, participants had 4.7 times the odds of reporting a lack of air movement, 1.4 more symptoms (p-value = 0.019) and a 2 bpm higher heart rate (p-value < 0.001) for a 1000 ppm increase in indoor CO2 concentration. These findings suggest that occupant health in green and conventional buildings is driven by both environmental perceptions and physiological pathways. PMID- 27713595 TI - Eurytemora carolleeae in the Laurentian Great Lakes revealed by phylogenetic and morphological analysis. AB - In the Laurentian Great Lakes, specimens of Eurytemora have been reported as E. affinis since its invasion in the late 1950s. During an intensive collection of aquatic invertebrates for morphological and molecular identification in Western Lake Erie in 2012-2013, several specimens of Eurytemora were collected. Analysis of these specimens identified them as the recently described species E. carolleeae Alekseev and Souissi 2011. This result led us to assess E. carolleeae's identifying features, geographic distribution and historical presence in the Laurentian Great Lakes in view of its recent description in 2011. Cytochrome oxidase I (COI) DNA sequences of Eurytemora specimens were identified as closer (2 - 4% different) to recently described E. carolleeae than to most Eurytemora affinis sequences (14% different). Eurytemora from other areas of the Great Lakes and from North American rivers as far west as South Dakota (Missouri River) and east to Delaware (Christina River) also keyed to E. carolleeae. Morphological analysis of archival specimens from 1962 and from all the Great Lakes were identified as E. carolleeae. Additionally, Eurytemora drawings in previous publications from studies in the Holarctic region were reassessed to determine if these specimens were E. carolleeae. Additional morphological characters that may distinguish the North American E. carolleeae from other taxa are also described. We conclude that E. carolleeae is the correct name for the species of Eurytemora that has inhabited the Great Lakes since its invasion, as established by both morphological and COI sequence comparisons to reference keys and sequence databases in present and archival specimens. PMID- 27713596 TI - [Focus on RNA polymerase II]. PMID- 27713597 TI - Sexual Orientation, Race, and Trauma as Predictors of Sexual Assault Recovery. AB - Sexual minorities and racial minorities experience greater negative impact following sexual assault. We examined recovery from sexual assault among women who identified as heterosexual and bisexual across racial groups. A community sample of women (N = 905) completed three yearly surveys about sexual victimization, recovery outcomes, race group, and sexual minority status. Bisexual women and Black women reported greater recovery problems. However, Black women improved more quickly on depression symptoms than non-Black women. Finally, repeated adult victimization uniquely undermined survivors' recovery, even when controlling for child sexual abuse. Sexual minority and race status variables and their intersections with revictimization play roles in recovery and should be considered in treatment protocols for sexual assault survivors. PMID- 27713599 TI - Influence of tree shape and evolutionary time-scale on phylogenetic diversity metrics. AB - During the last decades, describing, analysing and understanding the phylogenetic structure of species assemblages has been a central theme in both community ecology and macro-ecology. Among the wide variety of phylogenetic structure metrics, three have been predominant in the literature: Faith's phylogenetic diversity (PDFaith), which represents the sum of the branch lengths of the phylogenetic tree linking all species of a particular assemblage, the mean pairwise distance between all species in an assemblage (MPD) and the pairwise distance between the closest relatives in an assemblage (MNTD). Comparisons between studies using one or several of these metrics are difficult because there has been no comprehensive evaluation of the phylogenetic properties each metric captures. In particular it is unknown how PDFaith relates to MDP and MNTD. Consequently, it is possible that apparently opposing patterns in different studies might simply reflect differences in metric properties. Here, we aim to fill this gap by comparing these metrics using simulations and empirical data. We first used simulation experiments to test the influence of community structure and size on the mismatch between metrics whilst varying the shape and size of the phylogenetic tree of the species pool. Second we investigated the mismatch between metrics for two empirical datasets (gut microbes and global carnivoran assemblages). We show that MNTD and PDFaith provide similar information on phylogenetic structure, and respond similarly to variation in species richness and assemblage structure. However, MPD demonstrate a very different behaviour, and is highly sensitive to deep branching structure. We suggest that by combining complementary metrics that are sensitive to processes operating at different phylogenetic depths (i.e. MPD and MNTD or PDFaith) we can obtain a better understanding of assemblage structure. PMID- 27713598 TI - Shape Control of Colloidal Cu2-x S Polyhedral Nanocrystals by Tuning the Nucleation Rates. AB - Synthesis protocols for colloidal nanocrystals (NCs) with narrow size and shape distributions are of particular interest for the successful implementation of these nanocrystals into devices. Moreover, the preparation of NCs with well defined crystal phases is of key importance. In this work, we show that Sn(IV) thiolate complexes formed in situ strongly influence the nucleation and growth rates of colloidal Cu2-x S polyhedral NCs, thereby dictating their final size, shape, and crystal structure. This allowed us to successfully synthesize hexagonal bifrustums and hexagonal bipyramid NCs with low-chalcocite crystal structure, and hexagonal nanoplatelets with various thicknesses and aspect ratios with the djurleite crystal structure, by solely varying the concentration of Sn(IV)-additives (namely, SnBr4) in the reaction medium. Solution and solid-state 119Sn NMR measurements show that SnBr4 is converted in situ to Sn(IV)-thiolate complexes, which increase the Cu2-x S nucleation barrier without affecting the precursor conversion rates. This influences both the nucleation and growth rates in a concentration-dependent fashion and leads to a better separation between nucleation and growth. Our approach of tuning the nucleation and growth rates with in situ-generated Sn-thiolate complexes might have a more general impact due to the availability of various metal-thiolate complexes, possibly resulting in polyhedral NCs of a wide variety of metal-sulfide compositions. PMID- 27713600 TI - Association of Single Nucleotide Polymorphisms with Atrial Fibrillation and the Outcome after Catheter Ablation. AB - BACKGROUND: The association of gene variants with atrial fibrillation (AF) type and the recurrence of AF after catheter ablation in Taiwan is still unclear. In this study, we aimed to investigate the relationships between gene variants, AF type, and the recurrence of AF. METHODS: In our investigation, we examined 383 consecutive patients with AF (61.9 +/- 14.0 years; 63% men); of these 383 patients, 189 underwent catheter ablation for drug-refractory AF. Thereafter, the single nucleotide polymorphisms rs2200733, and rs7193343 were genotyped using real-time polymerase chain reaction. RESULTS: The rs7193343 variant was independently associated with non-paroxysmal AF (non-PAF). In the PAF group, the rs7193343 variant was independently associated with AF recurrence after catheter ablation. However, the rs2200733 variant was not associated with AF recurrence in this group. The combination of the rs7193343 and rs2200733 risk alleles was associated with a better predictive power in the PAF patients. In contrast, in the non-PAF group, the SNPs were not associated with recurrence. The rs7193343 and rs2200733 variants were not associated with different atrial voltage and activation times. CONCLUSIONS: The rs7193343 variants were associated with AF recurrence after catheter ablation in PAF patients but not in non-PAF patients. The rs7193343 CC variant was independently associated with non-PAF. PMID- 27713601 TI - Elevated Neutrophil-to-Lymphocyte Ratio Predicts Intermediate-Term Outcomes in Patients Who Have Advanced Chronic Kidney Disease with Peripheral Artery Disease Receiving Percutaneous Transluminal Angioplasty. AB - BACKGROUND: Inflammation plays an important role in the pathogenesis of cardiovascular disease in patients with advanced chronic kidney disease (CKD). Neutrophil-to-lymphocyte ratio (NLR), an inflammatory biomarker, has not been evaluated in patients who have advanced CKD with peripheral artery disease (PAD) undergoing percutaneous transluminal angioplasty (PTA), especially in Taiwan. METHODS: We retrospectively evaluated 148 advanced CKD (creatinine clearance rate <= 30 mL/min/1.73 m2) identified from a prospective registry in our hospital (303 PTA cases in total). Kaplan-Meier analysis with log-rank test was used to study event-free survival, and all univariables (p value < 0.1) were put into multivariate Cox regression analysis. RESULTS: During the mean follow-up time of 8.6 +/- 7.8 months, 35.1% of the cases achieved primary composite endpoint (all cause mortality or major amputation), 25.5% underwent death from any cause, and 14.9% underwent major or minor amputation. Rutherford grade 6, either NLR or NLR >= 3.76, and a history of hypertension had a positively prognostic impact on the occurrence of primary composite endpoint, whereas higher albumin level (>= 3.0 mg/dL) and technical success had a significantly protective effect. History of hypertension, either NLR or NLR >= 3.76, and age were associated with all-cause mortality. In addition, Rutherford 6, higher albumin level (>= 3.0 mg/dL), technical success, NLR, and age could predict the occurrence of major amputation. CONCLUSIONS: NLR, but not C-reactive protein or platelet-lymphocyte ratio, is an important prognostic predictor of all major clinical outcomes in patients with advanced CKD and PAD receiving PTA. Further studies are warranted to establish a better strategy and healthcare program in this clinical setting. PMID- 27713602 TI - Increased Platelet-to-Lymphocyte Ratios and Low Relative Lymphocyte Counts Predict Appropriate Shocks in Heart Failure Patients with ICDs. AB - BACKGROUND: Platelet-to-lymphocyte ratio (PLR) and relative lymphocyte count (L%) are commonly available tests that can be obtained from complete blood count. The aim of this study was to investigate the association between appropriate defibrillator therapy and PLR, and whether decreased lymphocyte count may predict appropriate implantable cardioverter defibrillator (ICD) shocks in heart failure (HF) patients. METHODS: A total of 147 patients with ischemic or non-ischemic HF who underwent ICD implantation for primary prevention were enrolled in this study. Peripheral venous blood samples were drawn on the same day as ICD implantation. White blood cell counts with differentials, red blood cell indices, and platelet counts were calculated with an automated blood cell counter. All patients were evaluated according to the presence of appropriate ICD therapy. RESULTS: Baseline ejection fraction was significantly lower in the appropriate shock received group (p = 0.040). Median PLR was significantly higher and L% was significantly lower in the appropriate shock received group (p < 0.001). In both ischemic and non-ischemic HF groups, median L% was significantly lower in the appropriate shock received group (p < 0.001; p = 0.006, respectively). In multivariable logistic regression analysis, only L% showed a strong association with appropriate shock therapy (p < 0.001). CONCLUSIONS: Higher PLRs are related to appropriate shocks in patients that received ICD with lower EF. Furthermore, decreased L% is independently associated with appropriate shocks in HF. PMID- 27713603 TI - The Early Predictive Value of Right Ventricular Strain in Epirubicin-Induced Cardiotoxicity in Patients with Breast Cancer. AB - BACKGROUND: As cancer therapies have improved, patient life spans have been extended but quality of life has been threatened by chemotherapy induced cardiotoxicity. Most cardiac complications remain unobserved until specific symptoms develop. Speckle-tracking echocardiography is a sensitive imaging modality in detecting early occult myocardial dysfunction. METHODS: A total number of 35 patients newly diagnosed with breast cancer and preparing for epirubicin therapy were prospectively recruited. Echocardiography, including speckle-tracking echocardiography, was performed sequentially at baseline (T1), after the first cycle (T2) and after the third cycle (T3) of epirubicin. At each visit, the severity of dyspnea was evaluated by the assessment scale. RESULTS: Compared with the baseline, right ventricular longitudinal strain (RVLS_FW) at T2 significantly declined (-22.49 +/- 4.97 vs. -18.48 +/- 4.46, p = 0.001), which was also positively associated with the development of dyspnea (R2 = 0.8, p = 0.01). At T3, both the left ventricular global longitudinal strain and RVLS_FW were significantly impaired (-21.4 +/- 4.12 vs. -16.94 +/- 6.81%; -22.49 +/- 4.97 vs. -16.86 +/- 7.27%, p = 0.01; 0.001, respectively). Also, the accumulating dose of epirubicin positively correlated with the development of dyspnea (R2 = 0.38, p = 0.04) and the decline of RVLS_FW (R2 = 0.53, p = 0.02). Notably, compared with the other echocardiographic parameters only RVLS_FW at the early stage (T2) significantly correlated with the development of dyspnea (odds ratio: 1.84, 95% confidence interval: 1.22-2.78, p = 0.04). CONCLUSIONS: RVLS_FW sensitively predicts dyspnea development in breast cancer patients receiving epirubicin therapy. However, larger scale studies are required to validate its role in long term patient survival. PMID- 27713604 TI - Echocardiography for Evaluation of Oncology Therapy-Related Cardiotoxicity. PMID- 27713605 TI - Impact of Statins Therapy for Ischemic Heart Disease Patients with Low-Density Lipoprotein Cholesterol Levels Less Than 100 mg/dL. AB - BACKGROUND: The objective of this study was to determine whether the use of statins prevents the progression of ischemic heart disease (IHD) in patients with low levels of low-density lipoprotein cholesterol (LDL-C). METHODS: We reviewed data obtained from IHD patients who underwent first percutaneous coronary intervention (PCI). Patients underwent follow-up coronary angiography (re-CAG) after PCI. However, only patients with LDL-C levels less than 100 mg/dL at PCI were included in this study. Ultimately, 92 patients were enrolled. All patients were divided into two groups: 1) patients who were treated with statins (n = 69), and 2) patients who were not treated with statins (n = 23). RESULTS: The two groups had similar LDL-C levels at PCI. At re-CAG, the ratio of patients who underwent PCI for de novo lesion in the statin group was lower than that in the non-statin group (12% vs. 48%) (p < 0.001). In multiple regression analysis, statin usage and LDL-C level at PCI were independent predictors of the ratio of patients undergoing PCI for de novo lesion. CONCLUSIONS: Statins therapy for patients whose LDL-C levels are less than 100 mg/dL has a beneficial effect on secondary prevention of IHD. PMID- 27713606 TI - Frequency of Vascular Inflammation and Impact on Neointimal Proliferation of Drug Eluting Stents in Porcine Coronary Arteries. AB - BACKGROUND: We aimed to describe the frequency of vascular inflammatory reactions with second generation drug eluting stents (DES) compared to first generation DES, and analyze the impact on inflammation and neointimal proliferation in a porcine coronary model. METHODS: A total of 26 stents (7 multi-link VISION, 6 CYPHER, 6 TAXUS and 7 XIENCE V) were deployed in the coronary arteries of 10 domestic swine for 28 days, after which each stent was harvested and processed (divided into 8 or 9 segments) for histomorphometric analysis. RESULTS: A total of 202 histological segments [146 DES and 56 bare metal stents (BMS)] were included in this study. The mean neointimal thickness was significantly reduced in the DES group compared to the BMS group. The DES group had higher injury scores (DES = 0.99 +/- 0.79 versus BMS = 0.67 +/- 0.44, p < 0.004), inflammatory scores (DES = 2.09 +/- 1.54 versus BMS = 0.64 +/- 0.98, p < 0.001) and presence of para-strut granulomas (DES = 35% versus BMS = 2%, p < 0.001). In logistic regression analysis, the presence of para-strut granulomas correlated with an area of stenosis > 50% (RR: 6.11, 95% CI: 2.97 to 12.59, p = 0.001). In the DES group, the second generation stents had a lower neointimal area (XIENCE V: 1.64 +/- 0.90 mm2) compared to the first generation stents (TAXUS: 2.36 +/- 1.56 mm2, p = 0.005; CYPHER 2.78 +/- 1.82 mm2, p = 0.001). The XIENCE V stents had lower inflammatory scores and lower frequency of para-strut granulomas compared to the first generation stents. CONCLUSIONS: Second generation DES had a lower incidence of vascular inflammatory reactions compared to first generation DES. This biological phenomenon appears to influence the patterns of neointimal formation. PMID- 27713607 TI - Impact of Atorvastatin Combined with Ezetimibe for the Treatment of Carotid Atherosclerosis in Patients with Coronary Heart Disease. AB - BACKGROUND: This study aimed to investigate the impact of atorvastatin (Ato) combined with ezetimibe (Eze) for the treatment of carotid atherosclerosis in patients with coronary heart disease (CHD). METHODS: One hundred and forty-eight CHD patients with carotid atherosclerosis were divided into the control (Ato alone) and combination (Ato and Eze) groups. The treatment course was 12 months; patient blood lipids, carotid intima-media thickness (CIMT), and carotid plaque area were measured before and after treatment. RESULTS: Twelve months after treatment, there was a decrease in the CIMT, and the horizontal and vertical axes of the carotid plaque areas in both groups, compared to pretreatment values. The serum low-density lipoprotein cholesterol (LDL-C) levels were significantly decreased (p < 0.05). There were statistically significant differences (p < 0.05) in the LDL-C (2.12 +/- 0.58 mmol/L vs. 2.63 +/- 0.56 mmol/L) and CIMT (1.06 +/- 0.12 mm vs. 1.13 +/- 0.11 mm) levels between the combination and the control groups after treatment. Compared to the control group, the horizontal (0.18 +/- 0.06 cm2 vs. 0.19 +/- 0.05 cm2) and vertical carotid arterial plaque areas (0.40 +/- 0.15 cm2 vs. 0.41 +/- 0.17 cm2) of the combination group were reduced after treatment. However, the difference was not statistically significant (p > 0.05). CONCLUSIONS: The combination of Ato and Eze further reduces LDL-C levels and CIMT, and affect the progression of carotid atherosclerosis in CHD patients with hypercholesterolemia. PMID- 27713608 TI - Aliskiren Inhibits Neointimal Matrix Metalloproteinases in Experimental Atherosclerosis. AB - BACKGROUND: The renin-angiotensin system (RAS) plays an important role in atherosclerosis. Acting via the angiotensin II receptor, type 1, oxidative stress increases and contributes to endothelial dysfunction and vascular inflammation. Renin exerts effects through a renin receptor causing an increase in the efficiency of angiotensinogen cleavage and facilitates angiotensin II (Ang II) generation and action on cell surfaces. Ang II enhances proliferation and migration of vascular smooth muscle cells, indicating a direct involvement of the RAS in smooth muscle cell proliferation during neointimal formation. Aliskiren, a direct renin inhibitor, is a new oral antihypertensive drug. However, the role of the direct renin inhibitor in neointimal formation and vascular matrix metalloproteinases remains unclear. METHODS: To investigate the effects of aliskiren on the expression of vascular matrix metalloproteinases, we evaluated the aortic neointimal formation of high-cholesterol-fed animals after vascular injury in vivo and the cellular function of the tumor necrosis factor-alpha stimulated human aortic smooth muscle cells in vitro. Thereafter, we evaluated vascular expression (by western blot), activity (by gelatin zymography) and molecular pathway. RESULTS: In this study we demonstrated that aliskiren reduced neointimal hyperplasia in hypercholesterolemic rabbits after vascular injury and the expression of matrix metalloproteinases in the neointima. Aliskiren also inhibited the expression and activities of matrix metalloproteinases on tumor necrosis factor-alpha (TNF-alpha)-stimulated human aortic smooth muscle cells via the mitogen-activated protein kinase pathway. CONCLUSIONS: The present study showed that aliskiren inhibited the expression of vascular matrix metalloproteinases. With these results, we have better clarified the potential role of renin inhibitors in human atherosclerosis. PMID- 27713609 TI - Secondhand Smoke Exposure Enhances Cardiac Fibrosis Effects on the Aging Rat Hearts. AB - BACKGROUND: Examining aging rats exposed to secondhand smoke (SHS) engenders changes in left ventricular remodeling due to age- or disease-dependent alterations. METHODS: Rats were placed in whole-body exposure chambers and exposed to 10 cigarettes. Filtered air was introduced into the chamber at a low rate. Rats were exposed to SHS for 30 min, twice a day, 5 days per week for 1 month. After 4 weeks SHS exposure, rats were sacrificed for morphological study with trichome staining and left ventricular remodeling related protein analysis using western blot. RESULTS: Characteristic fibrotic morphology in the left ventricle increased significantly with aging and exposure to SHS. Exposure to SHS elevated TGFbeta1/p-Smad2/3/CTGF and MMP2/MMP9 protein expression levels (p < 0.05). No significant differences in FGF-2 and UPA protein expression were noted as a result of SHS exposure. However, TIMP-1, TIMP-2, TIMP-3 and TIMP-4 protein expression were suppressed by SHS exposure. We also observed increased TGFbeta1/p Smad2/3/CTGF (p < 0.01), FGF-2/UPA (p < 0.05) and decreased TIMPs protein expression levels. Corresponding MMP2 and MMP9 upregulation occurred with aging and exposure to SHS. TGFbeta1/p-Smad2/3/CTGF and FGF-2/UPA protein expression from SHS exposure were higher than that from aging. In contrast, MMP2 and MMP9 were increased in aging rats compared with SHS exposed rats (p < 0.05); however, TIMP-1 (p < 0.01), TIMP-2 (p < 0.01) and TIMP-3 (p < 0.05) were decreased. TIMP-4 protein expression levels were decreased compared with SHS exposed rats (p < 0.01). CONCLUSIONS: Aging and SHS exposure in rats will produce elevated fibrosis. Exposure to SHS will accelerate aging and left ventricular fibrosis. PMID- 27713610 TI - Hydrogen Sulfide Modulates the S-Nitrosoproteome and the Mitochondrial Morphology in Endothelial Cells. AB - BACKGROUND: Hydrogen sulfide (H2S) is one of the endogenous gaseous molecules promoting the production of nitric oxide (NO) which has cardioprotective functions. However, the role of the H2S-mediated protein S-nitrosoproteome and its subsequent physiological response remains unclear. METHODS: Endothelial cells EAhy 926 were treated with 50 MUM of H2S for 2 hours. The NO bound S nitrosoproteins were purified by a biotin-switch and then digested by trypsin. Resulting peptides from control and H2S treatment were separately labeled by isobaric tag for relative and absolute quantitation 114/115, quantified by liquid chromatography tandem-mass spectrometry and analyzed by ingenuity pathway analysis (IPA) software. The microP software was applied to analyze the morphological changes of mitochondria. RESULTS: With the treatment of H2S, 416 S nitrosylated proteins were identified. IPA analysis showed that these proteins were involved in five signaling pathways. The NO-bound cysteine residues and the S-nitrosylation levels (115/114) were shown for ten S-nitrosoproteins. Western blot further verified the S-nitrosylation of thioredoxin-dependant peroxide reductase, cytochrome c oxidase and cytochrome b-c1 complex that are involved in the mitochondrial signaling pathway. H2O2-induced mitochondrial swelling can be reduced by the pretreatment of H2S. CONCLUSIONS: The H2S-mediated endothelial S nitrosoproteome has been confirmed. In the present study, we have proposed the cardioprotective role of H2S via maintaining mitochondrial homeostasis.

AB - Assessment of the pulmonary circulation status including pressure, resistance, size, and absence of anatomical distortion, is crucial to the successful Fontan operation. Most patients are found to have acceptable pulmonary arteries after previous palliation, although some degree of distortion is not uncommon. However, in rare instances, some patients have only one functioning lung with another pulmonary artery seriously hypoplastic or atretic. For theses patients, completion of a Fontan operation will be challenging. We reported a 17-year-old girl with a single ventricle and heterotaxy syndrome and only her left lung functioning, who underwent one-lung Fontan operation with a satisfactory result. PMID- 27713612 TI - Longitudinal Stent Deformation Caused by Retraction of the Looped Main Branch Guidewire. AB - A 66-year-old male was treated percutaneously for a bifurcation lesion of the left anterior descending coronary artery by provisional stenting using the jailed wire technique. After successfully stenting the main branch, retraction of the looped main branch guidewire was impossible. After using an intravascular ultrasound we discovered the guidewire was entangled with a stent strut. Thereafter, the proximal stent elongated after retraction. With the support of an over-the-wire microcatheter, we finally pulled out the entrapped guidewire. This rare complication should remind physicians that it is important to prevent the distal guidewire from being looped while retracting it through a stent, regardless of whether it is in the side branch or main vessel. If the guidewire becomes entangled with a stent, a microcatheter or low-profile balloon can be advanced to rescue it before the stent is damaged. Furthermore, the microcather should be maintained after successful retraction of the entangled guidewire to facilitate further wiring and subsequent rescue angioplasty as necessary.

AB - Endovascular stent-grafting is an alternative treatment for adult patent ductus arteriosus (PDA), especially in elderly patients. Regarding young adults, endovascular therapy is a reasonable choice if the landing zone is sufficient. In this study, we report on a young adult with PDA successfully treated with endovascular stent-grafting. PMID- 27713614 TI - Using Rivaroxaban as Thrombolytic Treatment for a Patient of Pedal Arch Arterial Thrombosis with Suboptimal Result of Endovascular Therapy. AB - A 77-year-old male with subacute right foot ischemia was treated with endovascular therapy to relieve total thrombosis of the pedal arch extending from the dorsalis pedis of the anterior tibial artery into the posterior tibial artery, plantar segment. Because the procedure was only partially successful, rivaroxaban was used for thrombolytic treatment resulting in improvement of the patient's ischemic pain and avoidance of gangrenous progression and surgical amputation. This is the first report describing successful recanalization of pedal arch arterial thrombosis using rivaroxaban in a patient after suboptimal results of endovascular therapy. PMID- 27713615 TI - Isolation and characterization of new secondary metabolites from Asphodelus microcarpus. AB - Phytochemical study of the ethanolic extract of Asphodelus microcarpus Salzm. et Viv. (Asphodelaceae) resulted in the isolation of two new compounds, methyl-1,4,5 trihydroxy-7-methyl-9,10-dioxo-9,10-dihydroanthracene-2-carboxylate (1), and (1R) 3,10-dimethoxy-5-methyl-1H-1,4-epoxybenzo[h]isochromene (2) as well as three known compounds; 3,4-dihydroxy-methyl benzoate (3), 3,4-dihydroxybenzoic acid (4), and 6-methoxychrysophanol (5). Compound 1 showed a potent activity against methicillin-resistant Staphylococcus aureus (MRSA) and Staphylococcus aureus with IC50 values of 1.5 and 1.2 ug/mL, respectively. Compound 3 showed antileishmanial activity with an IC50 value of 33.2 ug/mL. Compound 2 is the first isochromene possessing a highly strained 1,4-epoxy moiety. The structure elucidation of isolated metabolites was carried out using spectroscopic data, the absolute configuration of 2 based on optical rotation and electronic circular dichroism experiments and calculations. PMID- 27713616 TI - Cognitive Behavioural Suicide Prevention for Male Prisoners: Case examples. AB - Suicide is a serious public health problem but a problem that is preventable. This complex and challenging problem is particularly prevalent amongst prisoners; associated with a five-fold increase in risk compared to the general community. Being in prison can lead people to experience fear, distrust, lack of control, isolation, and shame, which is often experienced as overwhelming and intolerable with some choosing suicide as a way to escape. Few effective psychological interventions exist to prevent suicide although cognitive behaviour therapies appear to offer some promise. Offering cognitive behaviour suicide prevention (CBSP) therapy to high risk prisoners may help to reduce the likelihood of preventable self-inflicted deaths. In this paper we present three cases drawn from a randomised controlled trial designed to investigate the feasibility of CBSP for male prisoners. Implications of the current findings for future research and clinical practice are considered. PMID- 27713617 TI - Effects of laser in situ keratomileusis on mental health-related quality of life. AB - PURPOSE: The aims of our study were to investigate whether laser in situ keratomileusis (LASIK) improves health-related quality of life (HRQoL) and to identify factors that affect postoperative HRQoL. MATERIALS AND METHODS: A total of 213 Japanese patients who underwent primary LASIK were analyzed in this study. The average age of patients was 35.0+/-9.4 years. The subjects were asked to answer questions regarding subjective quality of vision, satisfaction, and quality of life (using the Japanese version of 36-Item Short Form Health Survey Version 2) at three time points: before LASIK, 1 month after LASIK, and 6 months after LASIK. Longitudinal changes over 6 months in the outputs of mental component summary (MCS) score and the physical component summary (PCS) score from the 36-Item Short Form Health Survey Version 2 questionnaire were compared between time points using a linear mixed-effects model. Delta MCS and PCS were calculated by subtracting the postoperative score (1 month after LASIK) from the preoperative score. Preoperative and postoperative factors associated with a change in the MCS score or PCS score were evaluated via a linear regression model. RESULTS: The preoperative MCS score was 51.0+/-9.4 and increased to 52.0+/ 9.8 and 51.5+/-9.6 at 1 month and 6 months after LASIK, respectively, and the trend for the change from baseline in MCS through 6 months was significant (P=0.03). PCS score did not change following LASIK. Delta MCS was significantly negatively associated with preoperative spherical equivalent, axial length, and postoperative quality of vision, after adjusting for potential confounding factors. CONCLUSION: Mental HRQoL is not lost with LASIK, and LASIK may improve mental HRQoL. Preoperative axial length may predict postoperative mental HRQoL. PMID- 27713618 TI - Radiolabeled tirofiban - a potential radiopharmaceutical for detection of deep venous thrombosis. AB - AIM: The aim of this study was to investigate the possibility of using 99mtechnetium (99mTc)-labeled tirofiban (a reversible antagonist of glycoprotein IIb/IIIa) for detection of deep venous thrombosis (DVT) in rats without causing an antiplatelet effect. METHODS: The ability of in vitro tirofiban to inhibit adenosine 5'-diphosphate (ADP)-induced platelet aggregation was evaluated using optical aggregometer. Binding of 99mTc-tirofiban to platelets was evaluated. Serum levels of unlabeled (a validated high performance liquid chromatography method) and 99mTc-tirofiban after single intravenous injection were evaluated in male Wistar rats with or without induced DVT (femoral vein ligation model), and the rats were also subjected to whole body scintigraphy. RESULTS: Tirofiban in vitro inhibits ADP-induced aggregation of human platelets in a dose- and concentration-dependent manner (10 nM to 2 MUM), but only if it is added before ADP and not after ADP. 99mTc labeling did not affect the ability of tirofiban to bind to either human or rat platelets, nor did it affect tirofiban pharmacokinetics in intact rats or in animals with induced DVT. When 99mTc tirofiban was injected to rats after induction of DVT, at a molar dose lower than the one showing only a weak antiaggregatory effect in vitro, whole body scintigraphy indicated localization of 99mTc-tirofiban around the place of the induced DVT. CONCLUSION: 99mTc labeling of tirofiban does not affect its ability to bind to glycoprotein IIb/IIIa or its in vivo pharmacokinetics in rats, either intact or with DVT. A low, nonantiaggregatory dose of 99mTc-tirofiban may be used to visualize DVT at an early stage. PMID- 27713619 TI - Spotlight on sirukumab for the treatment of rheumatoid arthritis: the evidence to date. AB - Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease primarily affecting synovial joints and is characterized by persistent high-grade systemic inflammation. Proinflammatory cytokines, particularly interleukin-6 (IL-6), are of crucial importance in the pathogenesis of the disease, driving both joint inflammation and extra-articular comorbidities. Tocilizumab, a humanized IL-6 receptor-inhibiting monoclonal antibody, has been the first, and, to date, the only, IL-6 inhibitor approved for the treatment of RA. Many studies have demonstrated the potency and effectiveness of tocilizumab in controlling disease activity and radiological progression of RA. These successful results have encouraged the development of novel IL-6 inhibitors, among which a promising agent is sirukumab (SRK), a human anti-IL-6 monoclonal antibody currently under evaluation in Phase II/III studies in patients with RA, systemic lupus erythematosus, giant-cell arteritis, and major depressive disorder. The evidence to date indicates SRK as an effective and well-tolerated new therapeutic tool for patients with active RA, with some preliminary data suggesting a specific beneficial impact on relevant systemic complications associated with the disease, such as depression and cardiovascular disease. Conversely, although pathophysiological considerations make plausible the hypothesis that IL-6 blockade with SRK may also be beneficial in the treatment of many diseases other than RA (either autoimmune or not), available clinical data in patients with systemic lupus erythematosus do not seem to support this view, also giving rise to potentially relevant concerns about drug safety. If large Phase III clinical trials currently in progress in patients with RA confirm the efficacy and tolerability of SRK, then in the long term, this drug could, in the near future, occupy a place in the treatment of the disease, potentially also opening the doors to a more extended use of SRK in a wide range of disorders in which IL-6 plays a key pathogenic role. PMID- 27713620 TI - Evaluation of effects of various drugs on platelet functions using phorbol 12 myristate 13-acetate-induced megakaryocytic human erythroid leukemia cells. AB - BACKGROUND: The hyperfunction and activation of platelets have been strongly implicated in the development and recurrence of arterial occlusive disease, and various antiplatelet drugs are used to treat and prevent such diseases. New antiplatelet drugs and many other drugs have been developed, but some drugs may have adverse effects on platelet functions. OBJECTIVE: The aim of this study was to establish an evaluation method for evaluating the effect and adverse effect of various drugs on platelet functions. MATERIALS AND METHODS: Human erythroid leukemia (HEL) cells were used after megakaryocytic differentiation with phorbol 12-myristate 13-acetate as an alternative to platelets. Drugs were evaluated by changes in intracellular Ca2+ concentration ([Ca2+]i) mobilization in Fura2 loaded phorbol 12-myristate 13-acetate-induced HEL cells. Aspirin and cilostazol were selected as antiplatelet drugs and ibuprofen and sodium valproate as other drugs. RESULTS: There was a positive correlation between [Ca2+]i and platelet aggregation induced by thrombin. Aspirin (5.6-560 uM) and cilostazol (5-10 uM) significantly inhibited thrombin-induced increases in [Ca2+]i in a concentration dependent manner. On the other hand, ibuprofen (8-200 uM) and sodium valproate (50-1,000 ug/mL) also significantly inhibited thrombin-induced increases in [Ca2+]i in a concentration-dependent manner. Furthermore, the interaction effects of the simultaneous combined use of aspirin and ibuprofen or sodium valproate were evaluated. When the inhibitory effect of aspirin was higher than that of ibuprofen, the effect of aspirin was reduced, whereas when the inhibitory effect of aspirin was lower than that of ibuprofen, the effect of ibuprofen was reduced. The combination of aspirin and sodium valproate synergistically inhibited thrombin-induced [Ca2+]i. CONCLUSION: It is possible to induce HEL cells to differentiate into megakaryocytes, which are a useful model for the study of platelet functions, and the quantification of the inhibition of thrombin-induced increases in [Ca2+]i is applicable to the evaluation of the effects of various drugs on platelets. PMID- 27713621 TI - "My patients are better than yours": optimistic bias about patients' medication adherence by European health care professionals. AB - OBJECTIVES: The objectives of this study were to determine the perceptions of European physicians, nurses, and pharmacists about the extent of nonadherence by patients in their country relative to their perception of nonadherence by their own patients, and to investigate the occurrence of optimistic bias about medication adherence. The study explored a key cognitive bias for prevalence and likelihood estimates in the context of health care professionals' beliefs about patients' use of medicines. METHODS: A cross-sectional online survey of 3,196 physicians (855), nurses (1,294), and pharmacists (1,047) in ten European countries (Austria, Belgium, England, France, Germany, Hungary, the Netherlands, Poland, Portugal, and Switzerland) was used. RESULTS: Participants differed in their perceptions of the prevalence of medication adherence initiation, implementation, and persistence present in their own patients with a chronic illness in comparison to patients with a chronic illness in general. Health care professionals demonstrated optimistic bias for initiation and persistence with medicine taking, perceiving their own patients to be more likely to initiate and persist with treatment than other patients, but reported significantly lower prevalence of medication adherence levels for their own patients than for patients in general. This finding is discussed in terms of motivational and cognitive factors that may foster optimistic bias by health care professionals about their patients, including heightened knowledge of, and positive beliefs about, their own professional competence and service delivery relative to care and treatment provided elsewhere. CONCLUSION: Health care professionals in Europe demonstrated significant differences in their perceptions of medication adherence prevalence by their own patients in comparison to patients in general. Some evidence of optimistic bias by health care professionals about their patients' behavior is observed. Further social cognitive theory-based research of health care professional beliefs about medication adherence is warranted to enable theory-based practitioner-focused interventions to be tested and implemented. PMID- 27713622 TI - Patient preferences for treatment of multiple sclerosis with disease-modifying therapies: a discrete choice experiment. AB - OBJECTIVES: To assess disease-modifying therapy (DMT) preferences in a population of patients with multiple sclerosis (MS) and to estimate the association between sociodemographic and clinical factors and these preferences. METHODS: Preferences for DMTs attributes were measured using a discrete choice experiment. Analysis of preferences was assessed using mixed-logit hierarchical Bayes regression. A multilinear regression was used to evaluate the association between the preferences for each attribute and patients' demographic and clinical characteristics. A Student's t-test or Welch's t-test was used for subgroup comparisons. RESULTS: A total of 125 patients were included in the final analysis (62.9% female, mean age 44.5 years, 71.5% with relapsing-remitting MS diagnosis). The most important factor for patients was the possibility of suffering from the side effects of the treatment (relative importance [RI] =50%), followed by a delay in disease progression (RI =19.4%), and route and frequency of administration (RI =14.3%). According to maximum acceptable risk, patients were willing to accept an increase of 3.8% in severity of side effects, for a delay of 1 year in disease progression. Treatment duration was the most prevalent factor affecting preferences, followed by the age of patients, type of MS, level of education, and the type of current treatment. Patients treated orally were significantly more concerned about the route and frequency of administration (P=0.026) than patients on injectable therapy. Naive patients stated significantly less importance to prevention of relapses (P=0.021) and deterioration of the capacity for performing usual daily life activities (P=0.015). Finally, patients with >5 years since diagnosis were significantly less concerned about preventing disease progression (P=0.021), and more concerned about treatment side effects (P=0.052) than compared with patients with <5 years of MS history. CONCLUSION: The most important attribute for MS patients was side effects of DMTs, followed by delay in disability progression. Experience with DMTs and time since MS diagnosis changed patients' preferences. These results give information to adjust new DMT treatment in order to satisfy patients' preferences and therefore, improve adherence to treatment. PMID- 27713623 TI - Patterns of scheduled follow-up appointments following hospitalization for heart failure: insights from an urban medical center in the United States. AB - OBJECTIVES: Although postdischarge outpatient follow-up appointments after a hospitalization for heart failure represent a potentially effective strategy to prevent heart failure readmissions, patterns of scheduled follow-up appointments upon discharge are poorly described. We aimed to characterize real-world patterns of scheduled follow-up appointments among adult patients with heart failure upon hospital discharge. PATIENTS AND METHODS: This was a retrospective cohort study performed at a large urban academic center in the United States among adults hospitalized with a principal diagnosis of congestive heart failure between January 1, 2013, and December 31, 2014. Patient demographics, administrative data, clinical parameters, echocardiographic indices, and scheduled postdischarge outpatient follow-up appointments were collected. RESULTS: Of the 796 patients hospitalized for heart failure, just over half of the cohort had a scheduled follow-up appointment upon discharge. Follow-up appointments were less likely among patients who were white and had heart failure with preserved ejection fraction and more likely among patients with Medicaid and chronic obstructive pulmonary disease. In an adjusted multivariable regression model, age >=65 years was inversely associated with a scheduled follow-up appointment upon hospital discharge, despite higher rates of several cardiovascular and noncardiovascular comorbidities. CONCLUSION: Just half of the patients discharged home following a hospitalization for heart failure had a follow-up appointment scheduled, representing a missed opportunity to provide a recommended care transition intervention. Despite a greater burden of both cardiovascular and noncardiovascular comorbidities, older adults (age >=65 years) were less likely to have a follow-up appointment scheduled upon discharge compared with younger adults, revealing a disparity that warrants further investigation. PMID- 27713624 TI - Evaluation of the Master's curriculum for elderly nursing: a qualitative study. AB - BACKGROUND: Improving the quality of health care and rehabilitation for the elderly is one of the most important priorities of the health care system. Given the importance of evaluating the strengths and weaknesses of any program after its implementation, this study was conducted to identify the advantages and weaknesses of a geriatric nursing program at Tehran University of Medical Sciences. METHODS: This was a qualitative study, and the study population comprised students, graduates, and professors of geriatric nursing at the Master of Science level. Data were collected through face-to-face interviews and focus groups. Sixteen interviews were conducted. The interview guide was used as a research tool. Interviews continued until data saturation was reached. Conventional content analysis was used to analyze the data. RESULTS: Three main themes including "motivation to enter geriatric nursing", "lack of employment groundwork", and "lack of practical implementation of the curriculum" were the main findings of the study. CONCLUSION: Efforts to restructure the administrative system and employment can deter geriatric nursing students from simply earning a degree and actually encourage them to learn the required content. Appraisal and improvement of education facilities for student recruitment can guarantee the practical implementation of the curriculum. Drafting policies to attract graduates in clinical environments, opening up employment opportunities, providing organizational positions for the recruitment of this group, as well as dedicating some wards for elderly special care and providing nursing care to elderly people only can increase students' motivation to learn and their hopes of good job prospects. PMID- 27713625 TI - Impact of pharmacist interventions in older patients: a prospective study in a tertiary hospital in Germany. AB - BACKGROUND: Inappropriate pharmacotherapy among older adults remains a critical issue in our health care systems. Besides polypharmacy and multiple comorbidities, the age-related pharmacokinetic and pharmacodynamic changes may increase the risk of adverse drug reactions and medication errors. OBJECTIVE: The main target of this study was to describe the characteristics of pharmaceutical interventions in two geriatric wards (orthogeriatric ward and geriatric day unit) of a general teaching hospital and to evaluate the clinical significance of the detected medication errors. MATERIALS AND METHODS: The study was conducted between August 2014 and October 2015 and was based on a triple approach that included validation of medical orders, medication reconciliation at patients' admission, and a predischarge planning appointment with the patient. The validation of medical orders was based on analyzing the suitability of the drugs prescribed, the drug dose depending on the patient's characteristics, the presence of contraindications and interactions between drugs, and the proposal of alternative drugs included in the hospital formulary. RESULTS: A total of 2,307 interventions associated to a medication error in 15,282 medical orders for 1,859 older patients were recorded. The greater part of the interventions carried out on the orthogeriatric ward at admission and at discharge were due to omission of a drug in the medical order (20.0%) and clinically significant interactions requiring monitoring (30.4%), respectively. The main factor triggering pharmacist's recommendations on the geriatric day unit was clinically significant interactions (21.1%). With regard to the clinical severity of the detected errors, 68.1% were considered significant, 24.8% were of minor significance, and 7.2% were clinically serious. CONCLUSION: Our findings show the importance of clinical pharmacist involvement in the optimization of pharmacotherapy in older adults, ensuring that they receive effective, safe, and efficient drug therapy. PMID- 27713626 TI - Increased mortality in patients with severe COPD associated with high-intensity exercise: a preliminary cohort study. AB - INTRODUCTION: Intensity of exercise is believed to be a key determinant of response to chronic obstructive pulmonary disease (COPD) rehabilitation. We hypothesized that a higher intensity of exercise, in combination with physiotherapist-led instructions and education in management of breathlessness, would lead to better self-management, possibly delaying calls to the emergency service and preventing hospitalization. OBJECTIVE: We aimed to test this hypothesis in a subsequent randomized trial, and in order to test study processes and estimate hospitalization rates, we did a small preliminary prospective cohort study on severe COPD patients referred to outpatient rehabilitation. METHODS: In 2013, four rehabilitation courses were scheduled (spring, summer, autumn, and winter) each lasting 8 weeks and including eight to ten patients. This preliminary study was designed as a controlled cohort study. The bi-weekly exercise sessions in the spring and autumn courses included a high-intensity walking exercise at 95% of estimated VO2 max for as long as possible. The other two rehabilitation courses included the usual walking exercise intensity (85% of estimated VO2 max). Hospitalization rates were assessed from the participants' medical records in an 18-month period. RESULTS: We were able to enroll 31 patients in total (15 in the high-intensity exercise group and 16 in regular intensity). There were no group differences in the hospitalization rates. However, during review of the medical records, we observed a striking mortality rate among participants who had attended the high-intensity rehabilitation courses (five deaths) compared to the standard rehabilitation (zero deaths). Four of the five deaths were COPD exacerbations. Fisher's exact test was statistically significant (P=0.046), as was a log-rank test (P=0.019) of the Kaplan-Meier estimated survival rates. CONCLUSION: These results from this small preliminary cohort study are alarming and raise concerns about the possible serious risks associated with high-intensity exercise rehabilitation of severe COPD patients. PMID- 27713628 TI - Can resistive breathing injure the lung? Implications for COPD exacerbations. AB - In obstructive lung diseases, airway inflammation leads to bronchospasm and thus resistive breathing, especially during exacerbations. This commentary discusses experimental evidence that resistive breathing per se (the mechanical stimulus) in the absence of underlying airway inflammation leads to lung injury and inflammation (mechanotransduction). The potential implications of resistive breathing-induced mechanotrasduction in COPD exacerbations are presented along with the available clinical evidence. PMID- 27713627 TI - Elevated circulating PAI-1 levels are related to lung function decline, systemic inflammation, and small airway obstruction in chronic obstructive pulmonary disease. AB - BACKGROUND: Plasminogen activator inhibitor-1 (PAI-1) and soluble urokinase-type plasminogen activator receptor (suPAR) participate in inflammation and tissue remolding in various diseases, but their roles in chronic obstructive pulmonary disease (COPD) are not yet clear. This study aimed to investigate if PAI-1 and suPAR were involved in systemic inflammation and small airway obstruction (SAO) in COPD. METHODS: Demographic and clinical characteristics, spirometry examination, and blood samples were obtained from 84 COPD patients and 51 healthy volunteers. Serum concentrations of PAI-1, suPAR, tissue inhibitor of metalloproteinase-1 (TIMP-1), Matrix metalloproteinase-9 (MMP-9), and C-reactive protein (CRP) were detected with Magnetic Luminex Screening Assay. Differences between groups were statistically analyzed using one-way analysis of variance or chi-square test. Pearson's partial correlation test (adjusted for age, sex, body mass index, cigarette status, and passive smoke exposure) and multivariable linear analysis were used to explore the relationships between circulating PAI-1 and indicators of COPD. RESULTS: First, we found that serum PAI-1 levels but not suPAR levels were significantly increased in COPD patients compared with healthy volunteers (125.56+/-51.74 ng/mL versus 102.98+/-36.62 ng/mL, P=0.007). Then, the correlation analysis showed that circulating PAI-1 was inversely correlated with pulmonary function parameters including the ratio of forced expiratory volume in 1 second to forced vital capacity (FEV1/FVC), FEV1/Pre (justified r=-0.308, P<0.001; justified r=-0.295, P=0.001, respectively) and SAO indicators such as FEV3/FVC, MMEF25-75/Pre (justified r=-0.289, P=0.001; justified r=-0.273, P=0.002, respectively), but positively related to the inflammatory marker CRP (justified r=0.351, P<0.001), the small airway remolding biomarker TIMP-1, and MMP-9 (justified r=0.498, P<0.001; justified r=0.267, P=0.002, respectively). Besides, multivariable linear analysis showed that FEV1/FVC, CRP, and TIMP-1 were independent parameters associated with PAI-1. CONCLUSION: Our findings first illustrate that elevated serum PAI-1 levels are related to the lung function decline, systemic inflammation, and SAO in COPD, suggesting that PAI-1 may play critical roles in the pathogenesis of COPD. PMID- 27713629 TI - Importance of fractional exhaled nitric oxide in the differentiation of asthma COPD overlap syndrome, asthma, and COPD. AB - BACKGROUND: Fractional exhaled nitric oxide (FeNO) is an easy, sensitive, reproducible, and noninvasive marker of eosinophilic airway inflammation. Accordingly, FeNO is extensively used to diagnose and manage asthma. Patients with COPD who share some of the features of asthma have a condition called asthma COPD overlap syndrome (ACOS). The feasibility of using FeNO to differentiate ACOS patients from asthma and COPD patients remains unclear. METHODS: From February 2013 to May 2016, patients suspected with asthma and COPD through physician's opinion were subjected to FeNO measurement, pulmonary function test (PFT), and bronchial hyperresponsiveness or bronchodilator test. Patients were divided into asthma alone group, COPD alone group, and ACOS group according to a clinical history, PFT values, and bronchial hyperresponsiveness or bronchodilator test. Receiver operating characteristic (ROC) curves were obtained to elucidate the clinical functions of FeNO in diagnosing ACOS. The optimal operating point was also determined. RESULTS: A total of 689 patients were enrolled in this study: 500 had asthma, 132 had COPD, and 57 had ACOS. The FeNO value in patients with ACOS was 27 (21.5) parts per billion (ppb; median [interquartile range]), which was significantly higher than that in the COPD group (18 [11] ppb). The area under the ROC curve was estimated to be 0.783 for FeNO. Results also revealed an optimal cutoff value of >22.5 ppb FeNO for differentiating ACOS from COPD patients (sensitivity 70%, specificity 75%). CONCLUSION: FeNO measurement is an easy, noninvasive, and sensitive method for differentiating ACOS from COPD. This technique is a new perspective for the management of COPD patients. PMID- 27713630 TI - Preparation and evaluation of a self-nanoemulsifying drug delivery system loaded with Akebia saponin D-phospholipid complex. AB - BACKGROUND: Akebia saponin D (ASD) exerts various pharmacological activities but with poor oral bioavailability. In this study, a self-nanoemulsifying drug delivery system (SNEDDS) based on the drug-phospholipid complex technique was developed to improve the oral absorption of ASD. METHODS: ASD-phospholipid complex (APC) was prepared using a solvent-evaporation method and characterized by infrared spectroscopy, differential scanning calorimetry, morphology observation, and solubility test. Oil and cosurfactant were selected according to their ability to dissolve APC, while surfactant was chosen based on its emulsification efficiency in SNEDDS. Pseudoternary phase diagrams were constructed to determine the optimized APC-SNEDDS formulation, which was characterized by droplet size determination, zeta potential determination, and morphology observation. Robustness to dilution and thermodynamic stability of optimized formulation were also evaluated. Subsequently, pharmacokinetic parameters and oral bioavailability of ASD, APC, and APC-SNEDDS were investigated in rats. RESULTS: The liposolubility significantly increased 11.4-fold after formation of APC, which was verified by the solubility test in n-octanol. Peceol (Glyceryl monooleate [type 40]), Cremophor(r) EL (Polyoxyl 35 castor oil), and Transcutol HP (Diethylene glycol monoethyl ether) were selected as oil, surfactant, and cosurfactant, respectively. The optimal formulation was composed of Glyceryl monooleate (type 40), Polyoxyl 35 castor oil, Diethylene glycol monoethyl ether, and APC (1:4.5:4.5:1.74, w/w/w/w), which showed a particle size of 148.0+/-2.7 nm and a zeta potential of -13.7+/-0.92 mV after dilution with distilled water at a ratio of 1:100 (w/w) and good colloidal stability. Pharmacokinetic studies showed that APC-SNEDDS exhibited a significantly greater Cmax1 (733.4+/-203.8 ng/mL) than ASD (437.2+/-174.2 ng/mL), and a greater Cmax2 (985.8+/-366.6 ng/mL) than ASD (180.5+/-75.1 ng/mL) and APC (549.7+/-113.5 ng/mL). Compared with ASD, Tmax1 and Tmax2 were both remarkably shortened by APC SNEDDS. The oral bioavailability in rats was enhanced significantly to 183.8% and 431.8% by APC and APC-SNEDDS, respectively. CONCLUSION: These results indicated that APC-SNEDDS was a promising drug delivery system to enhance the oral bioavailability of ASD. PMID- 27713632 TI - Is there any superiority among diagnostic methods in organizing pneumonia in terms of clinical features of the patients? AB - BACKGROUND: Organizing pneumonia (OP) can be idiopathic or secondary to some clinical situations. If an etiological cause is not present, this phenomenon is called cryptogenic OP. Secondary OP is associated with various diseases that are known to induce the OP. OBJECTIVES: The aim of this study was to evaluate the clinical features of the cases with OP and compare the patients diagnosed by bronchoscopic transbronchial biopsy with patients diagnosed by surgical lung biopsy. PATIENTS AND METHODS: Medical records of 41 patients diagnosed with OP between 2004 and 2014 were reviewed retrospectively. RESULTS: Totally, 41 patients with OP were identified. In all, 39.02% of the cases were diagnosed by bronchoscopic methods, and 60.97% of the cases were diagnosed by surgical procedures. Although the frequency of ground glass opacities, consolidations, and micronodules was higher in the group diagnosed by bronchoscopy, mass-like lesions were more common in the cases diagnosed by surgery. Bronchoscopy, performed in 30 patients totally, had a diagnostic efficacy of 53.33%. Diagnostic value of bronchoscopy was significantly higher in cryptogenic OPs. Although diffuse radiological pattern was more common in "successful bronchoscopy" group, frequency of focal pattern was higher in "failed bronchoscopy" group. Ground glass opacity in successful bronchoscopy group and mass-like lesions in failed bronchoscopy group reached significant differences. CONCLUSION: There were significant differences between the diagnostic procedures in terms of radiological patterns. This is the first study about the relationship between the diagnostic methods and the characteristics of OP. PMID- 27713631 TI - A longitudinal, event-related potential pilot study of adult obsessive-compulsive disorder with 1-year follow-up. AB - AIM: Earlier brain imaging research studies have suggested that brain abnormalities in obsessive-compulsive disorder (OCD) normalize as clinical symptoms improve. However, although many studies have investigated event-related potentials (ERPs) in patients with OCD compared with healthy control subjects, it is currently unknown whether ERP changes reflect pharmacological and psychotherapeutic effects. As such, the current study examined the neurocognitive components of OCD to elucidate the pathophysiological abnormalities involved in the disorder, including the frontal-subcortical circuits. METHODS: The Yale-Brown Obsessive-Compulsive Scale was used to evaluate 14 adult patients with OCD. The present study also included ten age-, sex-, and IQ-matched controls. The P300 and mismatch negativity (MMN) components during an auditory oddball task at baseline for both groups and after 1 year of treatment for patients with OCD were measured. RESULTS: Compared with controls, P300 amplitude was attenuated in the OCD group at Cz and C4 at baseline. Pharmacotherapy and psychotherapy treatment for 1 year reduced OCD symptomology. P300 amplitude after 1 year of treatment was significantly increased, indicating normalization compared with baseline at Fz, Cz, C3, and C4. We found no differences in P300 latency, MMN amplitude, or MMN latency between baseline and after one year of treatment. CONCLUSION: ERPs may be a useful tool for evaluating pharmacological and cognitive behavioral therapy in adult patients with OCD.

Identification of risks that predispose to coma are important in managing patients; however, the risk factors for nosocomial nontraumatic coma (NNC) are not well known. Our aim was to investigate the risk factors in patients with NNC. METHODS: A retrospective case-control design was used to compare patients with NNC and a control group of patients without coma in a population-based cohort of 263 participants from the neurological intensive care unit in Shuyang County People's Hospital of Northern China. Coma was diagnosed by a Glasgow Coma Scale score <=8. Adjusted odds ratios for patients with NNC were derived from multivariate logistic regression analyses. RESULTS: A total of 96 subjects had NNC. The prevalence of NNC was 36.5% among the subjects. Among these, 82% had acute cerebrovascular etiology. Most of the NNC usually occurred at day 3 after admission to the neurological intensive care unit. Patients with NNC had higher hospital mortality rates (67.7% vs 3%, P<0.0001) and were more likely to have a central herniation (47.9% vs 0%, P<0.001) or uncal herniation (11.5% vs 0%, P<0.001) than those without NNC. Multiple logistic regression showed that systemic inflammatory response syndrome-positive sepsis (odds ratio =4, 95% confidence interval =1.875-8.567, P<0.001) and acute respiratory failure (odds ratio =3.275, 95% confidence interval =1.014-10.573, P<0.05) were the factors independently associated with a higher risk of NNC. CONCLUSION: Systemic inflammatory response syndrome-positive sepsis and acute respiratory failure are independently associated with an increased risk of NNC. This information may be important for patients with NNC. PMID- 27713633 TI - Comparison of the acute-phase response after laparoscopic versus open aortobifemoral bypass surgery: a substudy of a randomized controlled trial. AB - PURPOSE: Minimally invasive surgical techniques have been shown to reduce the inflammatory response related to a surgical procedure. The main objective of our study was to measure the inflammatory response in patients undergoing a totally laparoscopic versus open aortobifemoral bypass surgery. This is the first randomized trial on subjects in this population. PATIENTS AND METHODS: This is a substudy of a larger randomized controlled multicenter trial (Norwegian Laparoscopic Aortic Surgery Trial). Thirty consecutive patients with severe aortoiliac occlusive disease eligible for aortobifemoral bypass surgery were randomized to either a totally laparoscopic (n=14) or an open surgical procedure (n=16). The inflammatory response was measured by perioperative monitoring of serum interleukin-6 (IL-6), IL-8, and C-reactive protein (CRP) at six different time points. RESULTS: The inflammatory reaction caused by the laparoscopic procedure was reduced compared with open surgery. IL-6 was significantly lower after the laparoscopic procedure, measured by comparing area under the curve (AUC), and after adjusting for the confounding effect of coronary heart disease (P=0.010). The differences in serum levels of IL-8 and CRP did not reach statistical significance. CONCLUSION: In this substudy of a randomized controlled trial comparing laparoscopic and open aortobifemoral bypass surgeries, we found a decreased perioperative inflammatory response after the laparoscopic procedure measured by comparing AUC for serum IL-6. PMID- 27713635 TI - Weekly nanoparticle albumin-bound paclitaxel in combination with cisplatin versus weekly solvent-based paclitaxel plus cisplatin as first-line therapy in Chinese patients with advanced esophageal squamous cell carcinoma. AB - OBJECTIVE: More effective regimens for advanced esophageal squamous cell carcinoma (ESCC) are urgently needed. Therefore, a retrospective study concerning the efficacy and safety of nanoparticle albumin-bound paclitaxel plus cisplatin (nab-TP) versus solvent-based paclitaxel plus cisplatin (sb-TP) as a first-line therapy was conducted in Chinese patients with advanced ESCC. METHODS: From June 2009 to June 2015, 32 patients were treated with nab-paclitaxel (125 mg/m2) on the first and eighth days (30 minutes infusion) and cisplatin (75 mg/m2) on the second day every 21 days (nab-TP arm). Also, 43 patients were treated with solvent-based paclitaxel (80 mg/m2) intravenously on the first and eighth days and the same dose of cisplatin (sb-TP arm). The two groups were compared in terms of objective response rate (ORR), disease control rate, progression-free survival (PFS), overall survival (OS), and safety profile. OS and PFS were estimated using Kaplan-Meier methods to determine associations between chemotherapy regimens and survival outcomes. RESULTS: Nab-TP demonstrated a higher ORR (50% vs 30%; P=0.082) and disease control rate (81% vs 65%; P=0.124) than sb-TP. Median OS was similar for nab-TP and sb-TP (12.5 vs 10.7 months; P=0.269). However, nab-TP resulted in a longer median PFS (6.1 months [95% confidence interval: 5.3-6.9]) than sb-TP (5.0 months [95% confidence interval: 4.4-5.6]) (P=0.029). The most common adverse events included anemia, leukopenia, neutropenia, febrile neutropenia, and thrombocytopenia in both the groups and no statistically significant differences were observed between the groups. With statistically significant differences, significantly less grade >=3 peripheral neuropathy, arthralgia, and myalgia occurred in the nab-TP arm (all P<0.05). Dose reduction, treatment delays, and second-line therapy were similar between the two regimens. There were no treatment-related deaths in either group. CONCLUSION: Nab paclitaxel plus cisplatin is found to be an effective and tolerable option for advanced ESCC in the People's Republic of China. PMID- 27713636 TI - Clinical use of cabozantinib in the treatment of advanced kidney cancer: efficacy, safety, and patient selection. AB - Clear cell (cc) renal cell carcinoma (RCC) is the most common type of cancer found in the kidney accounting for ~90% of all kidney cancers. In 2012, there were ~337,000 new cases of RCC diagnosed worldwide with an estimated 143,000 deaths, with the highest incidence and mortality in Western countries. Despite improvements in cancer control achieved with VEGF- and mTOR-targeted therapy for RCC, progression remains virtually universal and additional therapies are needed. The pivotal results of the METEOR trial led to cabozantinib's designation as a breakthrough drug by the US Food and Drug Administration and its approval for treatment of advanced RCC in 2016. Subsequent data from the CABOSUN trial, where caboxantinib is compared with sunitinib, will provide information on the relative activity of cabozantinib as first-line therapy for ccRCC. We review the development of cabozantinib in advanced RCC and its role in the treatment landscape for advanced RCC. PMID- 27713637 TI - Safety and efficacy of sunitinib in patients from Latin America: subanalysis of an expanded access trial in metastatic renal cell carcinoma. AB - BACKGROUND: Sunitinib is an approved treatment for metastatic renal cell carcinoma (mRCC). The safety profile and efficacy of sunitinib were confirmed in a global expanded access trial (ClinicalTrials.gov identifier: NCT00130897). This report presents a subanalysis of the final trial data from patients in Latin America. METHODS: Treatment-naive or previously treated mRCC patients aged >=18 years received oral sunitinib at a starting dose of 50 mg/day on a 4-weeks-on/2 weeks-off schedule. Treatment continued until disease progression, unacceptable toxicity, or withdrawal of consent. Safety was assessed regularly, and tumor measurements were scheduled per local practice (using Response Evaluation Criteria in Solid Tumors). RESULTS: In total, 348 patients from Latin America received sunitinib. Overall, 75% of patients had two or more sites of metastatic disease, 28% were aged >=65 years, 14% had an Eastern Cooperative Oncology Group performance status >=2, 9% had brain metastases, 9% had no prior nephrectomy, and 5% had non-clear cell RCC. Median treatment duration was 8 months, and median follow-up was 15.1 months. In total, 326 patients (94%) discontinued treatment, primarily due to death (41%) or lack of efficacy (22%). Most treatment-related adverse events were of mild to moderate severity (grade 1/2). Mucosal inflammation (reported in 54% of patients), diarrhea (53%), and asthenia (41%) were the most common any-grade treatment-related adverse events. Asthenia (12%), neutropenia (10%), and fatigue and thrombocytopenia (both 9%) were the most common grade 3/4 treatment-related adverse events. In total, 311 patients were included for tumor response, of whom eight (3%) had a complete response and 46 (15%) a partial response, yielding an objective response rate of 17%. Median duration of response, progression-free survival, and overall survival were 26.7, 12.1, and 16.9 months, respectively. CONCLUSION: The efficacy and safety profile of sunitinib in patients with mRCC from Latin America was comparable to that in the entire cohort of the global expanded access trial. PMID- 27713638 TI - Nanoradiopharmaceuticals for breast cancer imaging: development, characterization, and imaging in inducted animals. AB - Monoclonal antibodies as polymeric nanoparticles are quite interesting and endow this new drug category with many advantages, especially by reducing the number of adverse reactions and, in the case of radiopharmaceuticals, also reducing the amount of radiation (dose) administered to the patient. In this study, a nanoradiopharmaceutical was developed using polylactic acid (PLA)/polyvinyl alcohol (PVA)/montmorillonite (MMT)/trastuzumab nanoparticles labeled with technetium-99m (99mTc) for breast cancer imaging. In order to confirm the nanoparticle formation, atomic force microscopy and dynamic light scattering were performed. Cytotoxicity of the nanoparticle and biodistribution with 99mTc in healthy and inducted animals were also measured. The results from atomic force microscopy showed that the nanoparticles were spherical, with a size range of ~200-500 nm. The dynamic light scattering analysis demonstrated that over 90% of the nanoparticles produced had a size of 287 nm with a zeta potential of -14,6 mV. The cytotoxicity results demonstrated that the nanoparticles were capable of reaching breast cancer cells. The biodistribution data demonstrated that the PLA/PVA/MMT/trastuzumab nanoparticles labeled with 99mTc have great renal clearance and also a high uptake by the lesion, as ~45% of the PLA/PVA/MMT/trastuzumab nanoparticles injected were taken up by the lesion. The data support PLA/PVA/MMT/trastuzumab labeled with 99mTc nanoparticles as nanoradiopharmaceuticals for breast cancer imaging. PMID- 27713639 TI - Spotlight on pembrolizumab in non-small cell lung cancer: the evidence to date. AB - Immunotherapy with immune checkpoint inhibitors has opened a new arena in cancer therapeutics. Pembrolizumab is a highly selective anti-programmed cell death protein 1 (PD-1) antibody that has shown efficacy, leading to survival benefit and durable responses, in some patients with non-small cell lung cancer (NSCLC). It has been approved by the US Food and Drug Administration for the treatment of patients with metastatic NSCLC, whose tumors express PD-1 ligand 1 (PD-L1), with disease progression on or after platinum-containing chemotherapy. Here, we briefly discuss the PD-1/PD-L1 pathway and pembrolizumab before delving into the clinical trials that have led to its just-mentioned approval in NSCLC and ongoing clinical trials. Finally, we discuss the use of biomarkers, primarily PD-L1, in the context of pembrolizumab and NSCLC. PMID- 27713640 TI - The efficacy and safety of nivolumab in previously treated advanced non-small cell lung cancer: a meta-analysis of prospective clinical trials. AB - BACKGROUND: Nivolumab (BMS-936558/ONO-4538) was the first monoclonal antibody targeting programmed death (PD)-1. So far, a number of clinical trials on nivolumab have showed satisfactory efficacy in treating non-small-cell lung cancer (NSCLC). Herein, we present a meta-analysis evaluating the efficacy and safety of nivolumab for previously treated advanced NSCLC patients. METHODS: Electronic databases were searched for eligible literature. Data of objective response rate (ORR), disease control rate, overall survival, progression-free survival, and adverse effects (AEs) were extracted and pooled. Outcomes analyzed and presented in this study were according to the original data from nivolumab 3 mg/kg. RESULTS: In general, nine trials with 817 patients were included in this meta-analysis. The pooled ORR, disease control rate, 1-year overall survival rate, and 1-year progression-free survival rate were 20% (95% confidence interval [CI]: 17%-23%), 36% (95% CI: 22%-51%), 47% (95% CI: 40%-53%), 21% (95% CI: 18% 24%), respectively. In addition, the rate of grade 3-4 AEs was only 8% (95% CI: 6%-12%). Subgroup analysis showed no significant difference in terms of ORR between squamous and non-squamous NSCLC (odds ratio 1.23, 95% CI: 0.63-2.39, P=0.51). However, significantly greater ORR was presented in programmed cell death ligand 1 (PD-L1) positive cohort (ORR 31%, 95% CI: 24%-38%), compared to PD L1 negative cohort (ORR 12%, 95% CI: 9%-17%). The odds ratio for objective response to nivolumab in PD-L1 positive cases relative to negative cases was 3.08 (95% CI: 1.87-5.08, P<0.0001). CONCLUSION: In conclusion, nivolumab is a promising second-line agent for previously treated advanced NSCLC with manageable AEs. Both squamous and non-squamous NSCLC patients showed similar efficacy. In addition, patients with positive PD-L1 expression had better response from nivolumab. MICROABSTRACT: We present a meta-analysis evaluating the efficacy and safety of nivolumab for previously treated advanced NSCLC patients. In our study, nivolumab is a promising second-line agent for previously treated advanced NSCLC with manageable AEs. Both squamous and non-squamous NSCLC patients showed similar efficacy. In addition, patients with positive PD-L1 expression had better response from nivolumab. PMID- 27713641 TI - Radiation dose reduction for patients with extranodal NK/T-cell lymphoma with complete response after initial induction chemotherapy. AB - Previous studies have found that radiotherapy (RT) dose less than 50 Gy resulted in inferior outcomes for early stage extranodal NK/T-cell lymphoma (ENKTL). Nowadays, induction chemotherapy (CT) followed by RT consolidation is often used. For patients who get complete response (CR) after CT, whether RT dose can be safely reduced or not remains unknown. This retrospective study compared the survival outcomes between patients who received higher dose (>50 Gy) and lower dose (<=50 Gy) RT after CR was attained by CT. One hundred and forty four patients of early stage ENKTL got CR after induction CT and received RT consolidation. Thirty-one patients received lower dose RT (median 46 Gy, range, 36-50 Gy), and 113 patients received higher dose RT (median 56 Gy, range, 52-66 Gy). In univariate survival analysis, age >60, local tumor invasion, and non asparaginase-based CT were associated with inferior progression-free survival (PFS) and overall survival (OS). However, there were no differences in PFS and OS between patients treated with higher and lower dose RT, which was confirmed in the multivariate survival analysis. Furthermore, reduced dose RT did not affect local control rate. Most common RT-related side effects were grade 1/2 mucositis and dermatitis, and the incidence rate of grade 3 mucositis or dermatitis was lower in patients treated with reduced dose RT (9.7% vs 15.0% for mucositis, and 6.5% vs 17.7% for dermatitis). In conclusion, this study found that RT dose could be safely reduced without compromising survival outcomes and further improved RT related side effects. Prospective randomized controlled trials are warranted to validate our findings. PMID- 27713642 TI - Differential proteomics analysis of low- and high-grade of astrocytoma using iTRAQ quantification. AB - Astrocytoma is one of the most common types of brain tumor, which is histologically and clinically classified into four grades (I-IV): I (pilocytic astrocytoma), II (diffuse astrocytoma), III (anaplastic astrocytoma), and IV (glioblastoma multiforme). A higher grade astrocytoma represents a worse prognosis and is more aggressive. In this study, we compared the differential proteome profile of astrocytoma from grades I to IV. The protein samples from clinical specimens of grades I, II, III, and IV astrocytoma were analyzed by two dimensional liquid chromatography-tandem mass spectrometry and isobaric tags for relative and absolute quantitation and quantification. A total of 2,190 proteins were identified. Compared to grade I astrocytoma, 173 (12.4%), 304 (14%), and 462 (21.2%) proteins were aberrantly expressed in grades II, III, and IV, respectively. By bioinformatics analysis, the cell proliferation, invasion, and angiogenesis-related pathways increase from low- to high-grade of astrocytoma. Five differentially expressed proteins were validated by Western blot. Within them, matrix metalloproteinase-9 and metalloproteinase inhibitor 1 were upregulated in glioblastoma multiforme group; whereas fibulin-2 and -5 were downregulated in grade II/III/IV astrocytoma, and the negative expression was significantly associated with advanced clinical stage. Functional analysis showed that both fibulin-2 and -5 may exert an antitumor effect by inhibiting cell proliferation, in vitro migration/invasion in glioma cells. New molecular biomarkers are likely to be used for accurate classification of astrocytoma and likely to be the target for drug development. PMID- 27713643 TI - Postoperative prophylactic hepatic arterial infusion chemotherapy for stage III colorectal cancer: a retrospective study. AB - BACKGROUND: Radical resection is the main treatment for colorectal cancer (CRC), but metastasis or recurrence is common in which liver metastasis accounted for 83% of the cases. Therefore, the prognosis of patients with advanced CRC may be improved if liver metastasis is prevented. This study aims to investigate the efficacy of hepatic arterial infusion chemotherapy (HAIC) on liver metastases of stage III CRC patients after curative resection. METHODS: Between 2002 and 2008, 287 stage III CRC patients who had undergone radical resection were included in this study. According to postoperative adjuvant chemotherapy modality, these patients were divided into two groups. Patients in the combined therapy group received two cycles of HAIC plus four cycles of systemic chemotherapy, while patients in the monotherapy group received six cycles of systemic chemotherapy alone. The HAIC regimen consisted of hepatic arterial infusion of oxaliplatin (OXA, 85 mg/m2) on day 1 and 5-fluorouracil (5-FU, 2,400 mg/m2) on days 2 and 3 followed by a vein infusion of folinic acid (FA, 200 mg/m2) as a 2-hour infusion on days 2 and 3. The systemic chemotherapy regimen consisted of a 2-hour infusion of OXA (85 mg/m2) on day 1 followed by FA (200 mg/m2) as a 2-hour infusion on days 2 and 3, and by 5-FU (2,400 mg/m2) as a 48-hour infusion. This was repeated every 4 weeks. All cases were followed up for 5 years or until death. The 5-year overall survival, disease-free survival, liver metastases-free survival, and the overall liver metastases rates were retrospectively compared. RESULTS: Significant differences were found in the 5-year overall survival (combined therapy, 70.71%; monotherapy, 57.14%; P=0.014), disease-free survival (combined therapy, 69.29%; monotherapy, 55.78%; P=0.021), and liver metastases-free survival rates (combined therapy, 70%; monotherapy, 56.46%; P=0.019). CONCLUSION: Prophylactic adjuvant HAIC can prevent metachronous liver metastases and improve the prognosis of patients with stage III CRC after curative resection.

AB - PURPOSE: To retrospectively review the complications of ultrasound (US)-guided percutaneous microwave ablation (MWA) of renal cell carcinoma. PATIENTS AND METHODS: In this study, 101 patients with 105 tumors seen from April 2006 to Feb 2014 were enrolled retrospectively. The patients were treated with US-guided percutaneous MWA and were followed up with contrast-enhanced US and computed tomography or magnetic resonance imaging at 1, 3, and 6 months and every 6 months thereafter. RESULTS: Technical success was achieved in 99 of 105 tumors (94.3%). The median follow-up time was 25 (range 1.13-93.23) months. Among the 105 tumors, 26 complications in 24.8% of patients and 23 minor complications (Clavien-Dindo Grades I and II) in 21.9% of patients were noted, accounting for 88.5% of all complications. All the minor complications were cured. Three major complications (Clavien-Dindo Grade >=III) occurred in 2.9% of the patients, accounting for 11.5% of all complications: hydrothorax in two patients and bowel injury in one. The two patients who had hydrothorax post-MWA had a history of cirrhosis and were treated with catheter drainage. The bowel injury was treated surgically. In all patients, the changes in serum creatinine and urea nitrogen levels from before to after the procedure were small. CONCLUSION: US-guided percutaneous MWA is a beneficial treatment for renal cell carcinoma in selected patients; however, if the renal tumor is close to the bowel, or the patient has serious comorbidities or has undergone abdominal surgery, the procedure must be performed more carefully. PMID- 27713646 TI - Cost-effectiveness analysis of fesoterodine flexible dose in newly diagnosed patients with overactive bladder in routine clinical practice in Spain. AB - OBJECTIVE: To carry out cost-effectiveness analysis from the Spanish National Health System perspective, of treating overactive bladder (OAB), in newly diagnosed patients with two flexible doses of fesoterodine in routine clinical practice. PATIENTS AND METHODS: Economic evaluation of flexible-dose fesoterodine in newly diagnosed patients, including two treatment groups: standard escalating from 4 to 8 mg or fast escalating to 8 mg. Costs were estimated from health care resources utilization related to OAB, and were expressed in 2015 Euros. Quality adjusted life-years (QALYs) were obtained from overactive bladder questionnaire short form. Univariate and probabilistic sensitivity analyses were carried out. RESULTS: Three hundred and ninety symptomatic OAB patients treated with fesoterodine and newly diagnosed (141 in fast escalating group and 249 in standard escalating) were analyzed. Adjusted health care total costs were not statistically different; difference -?4.1 (confidence interval: -153.3; 25.1) P=0.842. QALYs were higher in fast escalating to high dose vs standard escalating group, resulting in a cost of -?16,020/QALY gained for fast escalating vs standard escalating group. CONCLUSION: When the cost-effectiveness threshold is set at a maximum value of ?30,000/QALY gained, fesoterodine fast escalating group was cost-effective vs standard escalating group 67.6% of the time. The treatment with fesoterodine, in female patients newly diagnosed, fast escalating to 8 mg was a cost-effective option relative to escalating traditionally from 4 to 8 mg, in the management of OAB in routine clinical practice, from the Spanish National Health System perspective. PMID- 27713647 TI - Efficacy and tolerance of an injectable medical device containing stable hybrid cooperative complexes of high- and low-molecular-weight hyaluronic acid: a monocentric 16 weeks open-label evaluation. AB - BACKGROUND: An injectable medical device containing stable hybrid cooperative complexes of high- and low-molecular-weight hyaluronic acid (HA) has been developed with characteristics suited for a global improvement of facial esthetics. OBJECTIVE: To evaluate the HA product performance in improving some key facial esthetic features. The study employed clinical scales, subjective evaluations, and facial skin objective measurements. METHODS: A single Italian site treated 64 female subjects aged 38-60 years, with injections at five predetermined points, on each side of the face, with a 4-week time lapse between the first and the second product administration. Subjects were evaluated after 4, 8, 12, and 16 weeks, using validated clinical scales, subjective evaluation, and objective quantitative outcome measures. Assessment of esthetic results included photographic documentation. RESULTS: Both the clinical and subjective assessments, and the majority of objective instrumental parameters indicated an improvement throughout the study and were already significant at week 4 or 8 and were still significant at week 16 (3 months after the second treatment). Minor and temporary local skin reactions were observed in 23% of subjects at the site of the injections, and the global judgment on tolerability was good or excellent, both in the investigators' opinion and volunteers' self-evaluation. CONCLUSION: Both subjective and objective improvement of the facial parameters was consistent with the bio-remodeling purpose, and persistent and still statistically significant at the end of the study. The tolerability and safety profile of the product were judged good or excellent both by investigators and volunteers. This study supports the claim for bio-remodeling of these stable hybrid cooperative complexes of low- and high-molecular-weight HA. PMID- 27713649 TI - Smartphone applications for chronic pain management: a critical appraisal. PMID- 27713648 TI - A novel paradigm to evaluate conditioned pain modulation in fibromyalgia. AB - INTRODUCTION: Application of noxious stimulation to one body area reduces pain sensitivity in a remote body area through activation of an endogenous pain inhibitory network, a behavioral phenomenon referred to as conditioned pain modulation (CPM). The efficiency of CPM is predictive of a variety of health outcomes, while impaired CPM has been associated with various chronic pain conditions. Current methods used to assess CPM vary widely, and interest in CPM method development remains strong. Here, we evaluated a novel method for assessing CPM in healthy controls and fibromyalgia (FM) patients using thumb pressure as both a test and conditioning stimulus. METHODS: Sixteen female FM patients and 14 matched healthy controls underwent CPM testing with thumbnail pressure as the test stimulus, and either cold water or noxious pressure as the conditioning stimulus. CPM magnitude was evaluated as the difference in pain rating of the test stimulus applied before and during the conditioning stimulus. RESULTS: In healthy controls, application of either pressure or cold water conditioning stimulation induced CPM as evidenced by a significant reduction in test stimulus pain rating during conditioning (P=0.007 and P=0.021, respectively). In contrast, in FM patients, neither conditioning stimulus induced a significant CPM effect (P>0.274). There was a significant difference in CPM magnitude for FM patients compared to healthy controls with noxious pressure conditioning stimulation (P=0.023); however, no significant difference in CPM was found between groups using cold water as a conditioning stimulus (P=0.269). CONCLUSION: The current study demonstrates that thumbnail pressure can be used as both a test and conditioning stimulus in the assessment of CPM. This study further confirms previous findings of attenuated CPM in FM patients compared with healthy controls. PMID- 27713650 TI - Glibenclamide population pharmacokinetic/pharmacodynamic modeling in South African type 2 diabetic subjects. AB - AIM: To determine the effective dose of glibenclamide by quantifying the dose response relationship in South African type 2 diabetic patients. PATIENTS AND METHODS: A total of 24 type 2 diabetic patients participated in a glibenclamide dose-escalation study during which glibenclamide, glucose, and insulin concentrations were quantified, while the dose of glibenclamide was progressively increased. All except four subjects contributed data on all dose-escalation steps; however, data from all 24 patients were included in the model-based analysis. Pharmacokinetic/pharmacodynamic (PKPD) relationships were modeled using the software Nonmem(r). Six models were utilized to explore the effect of alternative glibenclamide dose and plasma concentration inputs on various metrics of glucose response. RESULTS: Six models adequately described the experimental data. The effective dose for a glucose-lowering effect suggested by PKPD modeling is less than 5 mg/day. Doses beyond 5 mg/day do not meaningfully add to glibenclamide effects on blood-glucose response. CONCLUSION: The effective dose of glibenclamide, suggested by PKPD modeling, is less than 5 mg/day. Higher doses of glibenclamide, eg, 15 mg/day as originally recommended by the manufacturer, do not produce further decrease in the blood glucose level but may predispose the patients to adverse effects. PMID- 27713651 TI - Quality of life and use of health care resources among patients with chronic depression. AB - PURPOSE: This study estimates the health-related quality of life and the health care resource utilization of patients diagnosed with chronic depression (CD) in Spain. PATIENTS AND METHODS: We used the Spanish National Health Survey 2011 2012, a cross-sectional survey representative at the national level, that selects people aged between 18 and 64 years (n=14,691). We estimated utility indices through the EuroQol five-dimensional descriptive system questionnaire included in the survey. We calculated percentage use of health care resources (medical visits, hospitalizations, emergency services, and drug consumption) and average number of resources used when available. A systematic comparison was made between people diagnosed with CD and other chronic conditions (OCCs). The chi-square test, Mann-Whitney U-test, and Kruskal-Wallis test were used to determine the statistical significance of differences between comparison groups. Multivariate analyses (Poisson regression, logistic regression, and linear regression) were also carried out to assess the relationship between quality of life and consumption of health care resources. RESULTS: Approximately, 6.1% of the subjects aged between 18 and 64 years were diagnosed with CD (average age 48.3+/ 11 years, 71.7% females). After controlling for age, sex, and total number of comorbidities, a diagnosis of CD reduced utility scores by 0.09 (P<0.05) vs OCCs, and increased the average number of hospitalizations by 15%, the average number of days at hospital by 51%, and the average number of visits to emergency services by 15% (P<0.05). CD also increased the average number of visits to secondary care by 14% and visits to general practitioners by 4%. People with CD had a higher probability of consuming drugs than people with OCCs (odds ratio [OR]: 1.24, P<0.05), but only 38.6% took antidepressants. CONCLUSION: People with CD had significantly lower health-related quality of life than people with OCCs. CD was associated with increased hospital length of stay and involved a higher consumption of emergency services and drugs than OCCs.

PMID- 27713652 TI - Acquired hypofibrinogenemia: current perspectives. AB - Acquired hypofibrinogenemia is most frequently caused by hemodilution and consumption of clotting factors. The aggressive replacement of fibrinogen has become one of the core principles of modern management of massive hemorrhage. The best method for determining the patient's fibrinogen level remains controversial, and particularly in acquired dysfibrinogenemia, could have major therapeutic implications depending on which quantification method is chosen. This review introduces the available laboratory and point-of-care methods and discusses the relative advantages and limitations. It also discusses current strategies for the correction of hypofibrinogenemia. PMID- 27713654 TI - Iterative learning control with applications in energy generation, lasers and health care. AB - Many physical systems make repeated executions of the same finite time duration task. One example is a robot in a factory or warehouse whose task is to collect an object in sequence from a location, transfer it over a finite duration, place it at a specified location or on a moving conveyor and then return for the next one and so on. Iterative learning control was especially developed for systems with this mode of operation and this paper gives an overview of this control design method using relatively recent relevant applications in wind turbines, free-electron lasers and health care, as exemplars to demonstrate its applicability. PMID- 27713655 TI - Quantifying uncertainty in partially specified biological models: how can optimal control theory help us? AB - Mathematical models in biology are highly simplified representations of a complex underlying reality and there is always a high degree of uncertainty with regards to model function specification. This uncertainty becomes critical for models in which the use of different functions fitting the same dataset can yield substantially different predictions-a property known as structural sensitivity. Thus, even if the model is purely deterministic, then the uncertainty in the model functions carries through into uncertainty in model predictions, and new frameworks are required to tackle this fundamental problem. Here, we consider a framework that uses partially specified models in which some functions are not represented by a specific form. The main idea is to project infinite dimensional function space into a low-dimensional space taking into account biological constraints. The key question of how to carry out this projection has so far remained a serious mathematical challenge and hindered the use of partially specified models. Here, we propose and demonstrate a potentially powerful technique to perform such a projection by using optimal control theory to construct functions with the specified global properties. This approach opens up the prospect of a flexible and easy to use method to fulfil uncertainty analysis of biological models. PMID- 27713656 TI - Unifying dynamical and structural stability of equilibria. AB - We exhibit a fundamental relationship between measures of dynamical and structural stability of linear dynamical systems-e.g. linearized models in the vicinity of equilibria. We show that dynamical stability, quantified via the response to external perturbations (i.e. perturbation of dynamical variables), coincides with the minimal internal perturbation (i.e. perturbations of interactions between variables) able to render the system unstable. First, by reformulating a result of control theory, we explain that harmonic external perturbations reflect the spectral sensitivity of the Jacobian matrix at the equilibrium, with respect to constant changes of its coefficients. However, for this equivalence to hold, imaginary changes of the Jacobian's coefficients have to be allowed. The connection with dynamical stability is thus lost for real dynamical systems. We show that this issue can be avoided, thus recovering the fundamental link between dynamical and structural stability, by considering stochastic noise as external and internal perturbations. More precisely, we demonstrate that a linear system's response to white-noise perturbations directly reflects the intensity of internal white-noise disturbance that it can accommodate before becoming stochastically unstable.

(2010 J. Power Sources, 195, 5062-5066. (doi:10.1016/j.jpowsour.2010.02.013)) on the stress evolution during the lithiation/delithiation cycle of a thin film of amorphous silicon. Based on recent work that show a two-phase process of lithiation of amorphous silicon, we formulate a phase-field model coupled to elasticity in the framework of Larche-Cahn. Using an adaptive nonlinear multigrid algorithm for the finite-volume discretization of this model, our two-dimensional numerical simulations show the formation of a sharp phase boundary between the lithiated and the amorphous silicon that continues to move as a front through the thin layer. We show that our model captures the non-monotone stress loading curve and rate dependence, as observed in recent experiments and connects characteristic features of the curve with the structure formation within the layer. We take advantage of the thin film geometry and study the corresponding one-dimensional model to establish the dependence on the material parameters and obtain a comprehensive picture of the behaviour of the system. PMID- 27713658 TI - The Green's functions for peridynamic non-local diffusion. AB - In this work, we develop the Green's function method for the solution of the peridynamic non-local diffusion model in which the spatial gradient of the generalized potential in the classical theory is replaced by an integral of a generalized response function in a horizon. We first show that the general solutions of the peridynamic non-local diffusion model can be expressed as functionals of the corresponding Green's functions for point sources, along with volume constraints for non-local diffusion. Then, we obtain the Green's functions by the Fourier transform method for unsteady and steady diffusions in infinite domains. We also demonstrate that the peridynamic non-local solutions converge to the classical differential solutions when the non-local length approaches zero. Finally, the peridynamic analytical solutions are applied to an infinite plate heated by a Gauss source, and the predicted variations of temperature are compared with the classical local solutions. The peridynamic non-local diffusion model predicts a lower rate of variation of the field quantities than that of the classical theory, which is consistent with experimental observations. The developed method is applicable to general diffusion-type problems. PMID- 27713659 TI - Stress concentration in periodically rough Hertzian contact: Hertz to soft-flat punch transition. AB - We report on the elastic contact between a spherical lens and a patterned substrate, composed of a hexagonal lattice of cylindrical pillars. The stress field and the size of the contact area are obtained by means of numerical methods: a superposition method of discrete pressure elements and an iterative bisection-like method. For small indentations, a transition from a Hertzian to a soft-flat-punch behaviour is observed when the surface fraction of the substrate that is covered by the pillars is increased. In particular, we present a master curve defined by two dimensionless parameters, which allows one to predict the stress at the centre of the contact region in terms of the surface fraction occupied by pillars. The transition between the limiting contact regimes, Hertzian and soft-flat-punch, is well described by a rational function. Additionally, a simple model to describe the Boussinesq-Cerruti-like contact between the lens and a single elastic pillar, which takes into account the pillar geometry and the elastic properties of the two bodies, is presented. PMID- 27713661 TI - [Formula: see text]-symmetric graphene under a magnetic field. AB - We propose a [Formula: see text]-symmetrically deformed version of the graphene tight-binding model under a magnetic field. We analyse the structure of the spectra and the eigenvectors of the Hamiltonians around the K and K' points, both in the [Formula: see text]-symmetric and [Formula: see text]-broken regions. In particular, we show that the presence of the deformation parameter V produces several interesting consequences, including the asymmetry of the zero-energy states of the Hamiltonians and the breakdown of the completeness of the eigenvector sets. We also discuss the biorthogonality of the eigenvectors, which turns out to be different in the [Formula: see text]-symmetric and [Formula: see text]-broken regions. PMID- 27713660 TI - The interface of SrTiO3 and H2O from density functional theory molecular dynamics. AB - We use dispersion-corrected density functional theory molecular dynamics simulations to predict the ionic, electronic and vibrational properties of the SrTiO3/H2O solid-liquid interface. Approximately 50% of surface oxygens on the planar SrO termination are hydroxylated at all studied levels of water coverage, the corresponding number being 15% for the planar TiO2 termination and 5% on the stepped TiO2-terminated surface. The lateral ordering of the hydration structure is largely controlled by covalent-like surface cation to H2O bonding and surface corrugation. We find a featureless electronic density of states in and around the band gap energy region at the solid-liquid interface. The vibrational spectrum indicates redshifting of the O-H stretching band due to surface-to-liquid hydrogen bonding and blueshifting due to high-frequency stretching vibrations of OH fragments within the liquid, as well as strong suppression of the OH stretching band on the stepped surface. We find highly varying rates of proton transfer above different SrTiO3 surfaces, owing to differences in hydrogen bond strength and the degree of dissociation of incident water. Trends in proton dynamics and the mode of H2O adsorption among studied surfaces can be explained by the differential ionicity of the Ti-O and Sr-O bonds in the SrTiO3 crystal. PMID- 27713662 TI - Decadal variability of extreme wave height representing storm severity in the northeast Atlantic and North Sea since the foundation of the Royal Society. AB - Long-term estimation of extreme wave height remains a key challenge because of the short duration of available wave data, and also because of the possible impact of climate variability on ocean waves. Here, we analyse storm-based statistics to obtain estimates of extreme wave height at locations in the northeast Atlantic and North Sea using the NORA10 wave hindcast (1958-2011), and use a 5 year sliding window to examine temporal variability. The decadal variability is correlated to the North Atlantic oscillation and other atmospheric modes, using a six-term predictor model incorporating the climate indices and their Hilbert transforms. This allows reconstruction of the historic extreme climate back to 1661, using a combination of known and proxy climate indices. Significant decadal variability primarily driven by the North Atlantic oscillation is observed, and this should be considered for the long-term survivability of offshore structures and marine renewable energy devices. The analysis on wave climate reconstruction reveals that the variation of the mean, 99th percentile and extreme wave climates over decadal time scales for locations close to the dominant storm tracks in the open North Atlantic are comparable, whereas the wave climates for the rest of the locations including the North Sea are rather different. PMID- 27713663 TI - Edge wrinkling in elastically supported pre-stressed incompressible isotropic plates. AB - The equations governing the appearance of flexural static perturbations at the edge of a semi-infinite thin elastic isotropic plate, subjected to a state of homogeneous bi-axial pre-stress, are derived and solved. The plate is incompressible and supported by a Winkler elastic foundation with, possibly, wavenumber dependence. Small perturbations superposed onto the homogeneous state of pre-stress, within the three-dimensional elasticity theory, are considered. A series expansion of the plate kinematics in the plate thickness provides a consistent expression for the second variation of the potential energy, whose minimization gives the plate governing equations. Consistency considerations supplement a constraint on the scaling of the pre-stress so that the classical Kirchhoff-Love linear theory of pre-stretched elastic plates is retrieved. Moreover, a scaling constraint for the foundation stiffness is also introduced. Edge wrinkling is investigated and compared with body wrinkling. We find that the former always precedes the latter in a state of uni-axial pre-stretch, regardless of the foundation stiffness. By contrast, a general bi-axial pre-stretch state may favour body wrinkling for moderate foundation stiffness. Wavenumber dependence significantly alters the predicted behaviour. The results may be especially relevant to modelling soft biological materials, such as skin or tissues, or stretchable organic thin-films, embedded in a compliant elastic matrix. PMID- 27713664 TI - Mathematical and numerical framework for metasurfaces using thin layers of periodically distributed plasmonic nanoparticles. AB - In this paper, we derive an impedance boundary condition to approximate the optical scattering effect of an array of plasmonic nanoparticles mounted on a perfectly conducting plate. We show that at some resonant frequencies the impedance blows up, allowing for a significant reduction of the scattering from the plate. Using the spectral properties of a Neumann-Poincare type operator, we investigate the dependency of the impedance with respect to changes in the nanoparticle geometry and configuration. PMID- 27713665 TI - The interactive bending wrinkling behaviour of inflated beams. AB - A model is proposed based on a Fourier series method to analyse the interactive bending wrinkling behaviour of inflated beams. The whole wrinkling evolution is tracked and divided into three stages by identifying the bifurcations of the equilibrium path. The critical wrinkling and failure moments of the inflated beam can then be predicted. The global-local interactive buckling pattern is elucidated by the proposed theoretical model and also verified by non-contact experimental tests. The effects of geometric parameters, internal pressure and boundary conditions on the buckling of inflated beams are investigated finally. The results reveal that the interactive buckling characteristics of an inflated beam under bending are more sensitive to the dimensions of the structure and boundary conditions. We find that for beams which are simply supported at both ends or clamped and simply supported, boundary conditions may prevent the wrinkling formation. The results provide significant support for our understanding of the bending wrinkling behaviour of inflated beams.

Asymptotic solutions are obtained in the two limiting cases of a wide and a narrow pipette. PMID- 27713667 TI - Polyelectrolyte-graphene Nanocomposites for Biosensing Applications. AB - Due to their unique structure, the optical and mechanical properties graphene and its derivatives (e.g. graphene oxide, reduced graphene oxide) have captured the attention of a constantly increasing number of scientists with regards to biomolecule sensing. This mini review focuses on one specific type of sensor, that consisting of graphene and polyelectrolytes. Polyelectrolyte-graphene nanocomposites exhibit outstanding detection capabilities by synergistically combining the characteristics of both components, outperforming traditional sensors in many cases. Characteristics and mechanistic details of the most important polyelectrolyte-graphene based sensors will be discussed in detail in addition to some current challenges and future perspectives.

AB - Non-gay-identified men who have sex with men and women and who use alcohol and other drugs are a vulnerable population. Little is known about health and medical service provider interaction with these underserved clients. This article presents a thematic analysis of two focus groups undertaken with social and medical service providers regarding the needs of non-gay-identified men who have sex with men and women. Four emergent themes (labeling, constructions of masculinity, HIV/AIDS awareness, and treatment success) illustrate perceived barriers to HIV/AIDS prevention and treatment, as well as treatment success. Implications for policy, practice, and future research are discussed. PMID- 27713670 TI - Calprotectin: Clinical Applications in Pediatrics. AB - As seen over the past 20 years, calprotectin has evolved as a novel, non-invasive biomarker of gastrointestinal (GI) inflammation. We present this review of calprotectin in pediatrics. This article will focus on studies using calprotectin concentrations from different body fluids to monitor inflammation in different disease states and conditions. The ultimate goal of our group is to lay down a foundation as we consider using calprotectin prospectively as a marker of intestinal inflammation that could lead to further testing and possibly a marker of preparedness for feeding. We surveyed all published studies in English of calprotectin in neonates, infants, children, and adolescents through February 2014. We will discuss calprotectin's basic properties and analysis such as characteristics, identification, presence in body fluids, and maturational development. In addition, calprotectin's use in inflammatory diseases exploring both GI and non-GI conditions will be evaluated and compared with other serum markers presently available. Finally, a summary of our findings and discussion of future work that could be undertaken in order to render calprotectin as a more useful monitoring tool to the medical research community will complete the review. PMID- 27713671 TI - Stability and Sterility of Enoxaparin 8 mg/mL Subcutaneous Injectable Solution. AB - BACKGROUND: Enoxaparin is often diluted to accurately deliver doses to neonatal and infant patients. Current recommendations for dilutions may not be adequate for the smallest patients. METHODS: Review of dosing at our institution occurred, and an 8 mg/mL concentration of enoxaparin was chosen. A concentration of 8 mg/mL was compounded by diluting 0.4 mL of enoxaparin (100 mg/mL) into 4.6 mL of sterile water for injection into an empty sterile vial. Four syringes of the 8 mg/mL concentration were prepared by 5 technicians (20 total syringes). Stability and sterility testing occurred a 0, 7, 14, and 30 days. One-way repeated-measures analysis of variance was used to detect significant differences in Anti-Factor Xa concentrations at the testing time points. RESULTS: The dilution of enoxaparin was sterile at 30 days but exhibited significant degradation at the 30-day point (p < 0.05). CONCLUSION: A dilution of enoxaparin 8 mg/mL is stable and sterile for 14 days refrigerated but is not stable at 30 days. PMID- 27713672 TI - Outcomes in Postoperative Pediatric Cardiac Surgical Patients Who Received an Antiepileptic Drug. AB - BACKGROUND: Advances in cardiac operations over the last few decades, including corrective operations in early life, have dramatically increased the survival of children with congenital heart disease. However, postoperative care has been associated with neurologic complications, with seizures being the most common manifestation. The primary objective of this study is to describe the outcomes in pediatric patients who received an antiepileptic drug (AED) post-cardiac surgery. METHOD: A retrospective cohort study was performed in all patients less than 18 years of age who received an AED in the cardiovascular intensive care unit at Texas Children's Hospital from June 2002 until June 2012. Cardiac surgical patients initiated on phenobarbital, phenytoin, and levetiracetam were queried. Patients were excluded if the AED was not initiated on the admission for surgery. Patients who received 1 AED were compared to patients who received 2 AED, and differences in outcomes examined between the 3 AEDs used were evaluated. RESULTS: A total of 37 patients met the study criteria. Patients were initiated on an AED a median of 4 days following surgery and became seizure free a median of 1 day after initiation, with 65% remaining seizure free after the first dose. Half of all patients required 2 AEDs for seizure control, with a higher proportion of adolescents requiring 2 AEDs (p = 0.04). No differences were found when comparing the collected outcomes between phenobarbital, fosphenytoin, or levetiracetam. CONCLUSION: No adverse events were reported with the AEDs reviewed. Further work is necessary to evaluate long-term neurodevelopmental outcomes in this population and whether outcomes are a result of the AED or of other clinical sequelae. PMID- 27713673 TI - Does Combination Therapy With Vancomycin and Piperacillin-Tazobactam Increase the Risk of Nephrotoxicity Versus Vancomycin Alone in Pediatric Patients? AB - OBJECTIVES: To determine if the incidence of nephrotoxicity is higher in pediatric patients treated with the combination of vancomycin and piperacillin tazobactam, compared to patients treated with vancomycin alone. Secondary objectives were to determine if admission to an intensive care unit (ICU), higher serum vancomycin trough concentrations (>15 mg/L), or receipt of other nephrotoxic agents were related to the development of nephrotoxicity. METHODS: This was a retrospective, single-center, cohort study of 79 patients treated with vancomycin and 106 patients treated with vancomycin and pipracillin/tazobacatam (TZP). Serum creatinine was trended to determine if patients had nephrotoxicity, which was defined as at least a 100% increase in serum creatinine or an increase of >=0.5 mg/dL from the baseline value. Fisher's exact test was used to compare the incidence of nephrotoxicity in the vancomycin group to the combination group. Secondary objectives were evaluated by using relative risk (RR). RESULTS: Nephrotoxicity developed in 3 of 79 patients (3.8%) in the vancomycin group and in 25 of 106 patients (23.6%) on combination therapy (p = 0.0001). In patients receiving only vancomycin, there was no statistically significant increase in nephrotoxicity for patients in the ICU (RR 1.85, 95% confidence interval [CI] 0.175-19.62, p = 0.61), those with higher vancomycin troughs (RR 2.32, CI 0.226 23.86, p = 0.48), or those receiving other nephrotoxic medications (RR 2.94, CI 0.2779-31.05, p = 0.37). In the combination group, having higher serum vancomycin trough concentrations increased the risk of nephrotoxicity (RR 5.22, CI 2.407 11.306, p < 0.0001). CONCLUSIONS: Combination therapy with vancomycin and TZP is potentially more nephrotoxic than vancomycin alone. ICU admissions, high vancomycin troughs (>15 mg/L), and concomitant nephrotoxic medications cannot be excluded as risk factors for the observed increase in nephrotoxicity in patients receiving vancomycin and TZP. PMID- 27713674 TI - Impact of Computerized Provider Order Entry on Total Parenteral Nutrition in the Neonatal Intensive Care Unit. AB - OBJECTIVES: To determine if computerized provider order entry (CPOE) implementation impacts the time it takes for preterm neonates to reach their parenteral macronutrient goals. METHODS: Retrospective review of neonates <1750 g receiving parenteral nutrition (PN) before and after the implementation of CPOE. Primary outcome was the attainment of parenteral macronutrient goals. Secondary outcomes included time to attainment, the frequency of electrolyte abnormalities, and the incidence of required adjustments made to PN orders by verification pharmacists. RESULTS: Goal PN was achieved by 12/47 (25.5%) intervention vs. 2/44 (4.5%) control group infants (p < 0.05). This goal was attained in 10.8 +/- 7.5 days in the intervention group and 10 +/- 4.2 days in the control group (p = 0.90). Goal protein was reached by 74.5% of CPOE patients vs. 36.4% of controls, p < 0.05. Lipid goals were achieved by 98% vs. 100% (p = 0.33) of patients and were attained at an average of 1.5 +/- 0.8 days vs. 2.0 +/- 1.1 days (p < 0.05). Abnormal serum electrolyte values occurred more frequently in the control group (0.79 vs. 1.12/day PN). Adjustments by a verification pharmacist were required in 5.6% of CPOE compared with 30.4% of control group orders (p < 0.05). CONCLUSIONS: CPOE parenteral nutrition increased the proportion of preterm neonates attaining overall macronutrient goals. With CPOE, protein goals were reached by more patients and goal lipids were achieved faster. This system also decreased the number of pharmacist interventions during verification of PN orders and appeared to positively impact the incidence of serum electrolyte disturbances. PMID- 27713675 TI - Pharmacist-Led Model to Reduce Hospital Readmissions in Medically Complex Children. AB - OBJECTIVES: This pilot study investigated the feasibility and effect on health care utilization of medically complex children participating in a pharmacist-led model for care coordination. Quality of life and satisfaction with care were secondarily assessed for each patient. METHODS: Four medically complex children were enrolled and contacted by the pharmacist weekly for 5 consecutive months. Time for each encounter with a patient was collected. Each patient's hospital admissions, days of stay, emergency department visits, and clinic visits were recorded. At enrollment and at the end of the study, each caregiver completed the PedsQL 4.0 questionnaire to evaluate the child's quality of life and the Patient Assessment of Care for Chronic Conditions questionnaire to assess satisfaction with care. Patients aged 5 years and older completed an age-appropriate version of the PedsQL 4.0 as well. RESULTS: The pharmacist spent on average 60 to 80 minutes per patient per week. Hospital admissions and days of stay decreased for 3 patients and increased for 1 patient during this study. Quality of life increased for 2 patients and decreased for 2 patients and satisfaction with care increased for all 4 caregivers. CONCLUSIONS: This model was feasible for a pharmacist to coordinate and required frequent physician involvement. Health care utilization varied between patients, but overall decreased for the 4 patients pooled. Changes in quality of life varied and may be attributed to using a survey that was not specific to medically complex children. Overall, caregivers were highly satisfied with this service and the health care their child received. PMID- 27713676 TI - Meropenem-Induced Neutropenia in a Neonate. AB - Postmarketing surveillance has associated meropenem with the development of hematologic abnormalities, including agranulocytosis, neutropenia, and leukopenia, but the exact incidence in children is unknown. The case describes a full-term, 26-day-old neonate admitted for a sepsis workup. She was found to have a blood culture positive for Enterobacter cloacae and suspected meningitis and was initiated on meropenem 40 mg/kg/dose intravenously every 8 hours. On day 14 of antibiotic treatment, the patient developed an isolated neutropenia with an absolute neutrophil count of 288 cells/mm3. Meropenem was discontinued on hospital day 20, and a follow-up complete blood cell count 2 months later confirmed resolution of the hematologic abnormality. Clinicians should monitor complete blood cell counts diligently in children who receive large doses and prolonged courses of meropenem. PMID- 27713678 TI - Correspondence. PMID- 27713677 TI - Intraoperative Anaphylactic Reaction: Is it the Floseal? AB - When hemodynamic or respiratory instability occurs intraoperatively, the inciting event must be determined so that a therapeutic plan can be provided to ensure patient safety. Although generally uncommon, one cause of cardiorespiratory instability is anaphylactic reactions. During anesthetic care, these most commonly involve neuromuscular blocking agents, antibiotics, or latex. Floseal is a topical hemostatic agent that is frequently used during orthopedic surgical procedures to augment local coagulation function and limit intraoperative blood loss. As these products are derived from human thrombin, animal collagen, and animal gelatin, allergic phenomenon may occur following their administration. We present 2 pediatric patients undergoing posterior spinal fusion who developed intraoperative hemodynamic and respiratory instability following use of the topical hemostatic agent, Floseal. Previous reports of such reactions are reviewed, and the perioperative care of patients with intraoperative anaphylaxis is discussed. PMID- 27713679 TI - PPAG INDUCTS NEW FELLOWS. PMID- 27713680 TI - The influence of drinking motives on hookah use frequency among young multi substance users. AB - PURPOSE: The present work examined the influence of drinking motives on hookah use frequency among individuals reporting both alcohol and hookah use (multi substance users). Despite growing documentation of cross-substance effects between motives and substance use, limited research has examined these relationships specifically with respect to hookah use. METHODS: Participants were 134 (75.37% female) hookah and alcohol users, aged 18-47 years (M = 22.17, SD = 3.66) who completed measures of substance use, drinking motives, and reported demographic information. Structural equation modeling (SEM) was employed to investigate the predictive value of drinking motives on hookah use frequency, age taken into account. RESULTS: Findings showed that hookah use was negatively associated with age (beta = -.22, p <= .01). The model regressing hookah use on the four drinking motives provided adequate fit (chi2 = 314.31, df = 180, p < .05, CFI = .92, RMSEA = .075 [95% CI, .06-.09]). Hookah use was associated negatively with social motives (beta = -.43, p < .001) and positively with conformity motives (beta = .24, p <= .05). CONCLUSIONS: These findings are consistent with multi-substance use literature suggesting that drinking motives are associated with the use of other substances, including increased hookah use frequency. Additional examinations of cross-substance cognitive processes are needed, particularly with respect to understanding whether hookah use among multi substance users may be contingent in part on individual factors including negative affectivity. PMID- 27713681 TI - Mass spectrometry-based approaches to targeted quantitative proteomics in cardiovascular disease. AB - Mass spectrometry-based proteomics methodology has become an important tool in elucidating some of the underlying mechanisms involved in cardiovascular disease. The present review provides details on selected important protein targets where highly selective and specific mass spectrometry-based approaches have led to important new findings and provided new mechanistic information. The role of six proteins involved in the etiology of cardiovascular disease (acetylated platelet cyclooxygenase-1, serum apolipoprotein A1, apolipoprotein C-III, serum C-reactive protein, serum high mobility group box-1 protein, insulin-like growth factor I) and their quantification has been discussed. There are an increasing number of examples where highly selective mass spectrometry-based quantification has provided new important data that could not be obtained with less labor intensive and cheaper immunoassay-based procedures. It is anticipated that these findings will lead to significant advances in a number of important issues related to the role of specific proteins in cardiovascular disease. The availability of a new generation of high-resolution high-sensitivity mass spectrometers will greatly facilitate these studies so that in the future it will be possible to analyze serum proteins of relevance to cardiovascular disease with levels of specificity and/or sensitivity that cannot be attained by immunoassay-based procedures. PMID- 27713682 TI - Enantiomeric Profiling of Chiral Pharmacologically Active Compounds in the Environment with the Usage of Chiral Liquid Chromatography ?Coupled with Tandem Mass Spectrometry. AB - The issue of drug chirality is attracting increasing attention among the scientific community. The phenomenon of chirality has been overlooked in environmental research (environmental occurrence, fate and toxicity) despite the great impact that chiral pharmacologically active compounds (cPACs) can provoke on ecosystems. The aim of this paper is to introduce the topic of chirality and its implications in environmental contamination. Special attention has been paid to the most recent advances in chiral analysis based on liquid chromatography coupled with mass spectrometry and the most popular protein based chiral stationary phases. Several groups of cPACs of environmental relevance, such as illicit drugs, human and veterinary medicines were discussed. The increase in the number of papers published in the area of chiral environmental analysis indicates that researchers are actively pursuing new opportunities to provide better understanding of environmental impacts resulting from the enantiomerism of cPACs. PMID- 27713685 TI - Spectral Transfer Learning Using Information Geometry for a User-Independent Brain-Computer Interface. AB - Recent advances in signal processing and machine learning techniques have enabled the application of Brain-Computer Interface (BCI) technologies to fields such as medicine, industry, and recreation; however, BCIs still suffer from the requirement of frequent calibration sessions due to the intra- and inter individual variability of brain-signals, which makes calibration suppression through transfer learning an area of increasing interest for the development of practical BCI systems. In this paper, we present an unsupervised transfer method (spectral transfer using information geometry, STIG), which ranks and combines unlabeled predictions from an ensemble of information geometry classifiers built on data from individual training subjects. The STIG method is validated in both off-line and real-time feedback analysis during a rapid serial visual presentation task (RSVP). For detection of single-trial, event-related potentials (ERPs), the proposed method can significantly outperform existing calibration free techniques as well as outperform traditional within-subject calibration techniques when limited data is available. This method demonstrates that unsupervised transfer learning for single-trial detection in ERP-based BCIs can be achieved without the requirement of costly training data, representing a step forward in the overall goal of achieving a practical user-independent BCI system.

AB - Autism spectrum disorder (ASD) is a heterogeneous group of disorders which occurs with numerous medical conditions. In previous research, subtyping in ASD has been based mostly on cognitive ability and ASD symptom severity. The aim of the current study was to investigate whether specific medical conditions in ASD are associated with unique behavioral profiles. The medical conditions included in the study were macrocephaly, microcephaly, developmental regression, food selectivity, and sleep problems. The behavioral profile was composed of cognitive ability, adaptive skills, and autism severity, and was examined in each of the aforementioned medical conditions. The study population included 1224 participants, 1043 males and 181 females (M:F ratio = 5.8:1) with a mean age of 49.9 m (SD = 29.4) diagnosed with ASD using standardized tests. Groups with and without the specific medical conditions were compared on the behavioral measures. Developmental regression was present in 19% of the population and showed a more severe clinical presentation, with lower cognitive abilities, more severe ASD symptoms, and more impaired adaptive functioning. Microcephaly was observed in 6.3% of the population and was characterized by a lower cognitive ability and more impaired adaptive functioning in comparison to the normative head circumference (HC) group. Severe food selectivity was found in 9.8% and severe sleep problems in 5.1% of the ASD population. The food selectivity and sleep problem subgroups, both showed more severe autism symptoms only as described by the parents, but not per the professional assessment, and more impaired adaptive skills. Macrocephaly was observed in 7.9% of the ASD population and did not differ from the normative HC group in any of the examined behavioral measures. Based on these findings, two unique medical-behavioral subtypes in ASD that affect inherited traits of cognition and/or autism severity were suggested. The microcephaly phenotype occurred with more impaired cognition and the developmental regression phenotype with widespread, more severe impairments in cognition and autism severity. In contrast, severe food selectivity and sleep problems represent only comorbidities to ASD that affect functioning. Defining specific subgroups in ASD with a unique biological signature and specific behavioral phenotypes may help future genetic and neuroscience research.

AB - Methamphetamine (METH) is one of the psychostimulants that is co-abused with ethanol. Repeated exposure to high dose of METH has been shown to cause increases in extracellular glutamate concentration. We have recently reported that ethanol exposure can also increase the extracellular glutamate concentration and downregulate the expression of glutamate transporter subtype 1 (GLT-1). GLT-1 is a glial transporter that regulates the majority of extracellular glutamate. A Wistar rat model of METH and ethanol co-abuse was used to examine the expression of GLT-1 as well as other glutamate transporters such as cystine/glutamate exchanger (xCT) and glutamate aspartate transporter (GLAST). We also examined the body temperature in rats administered METH, ethanol or both drugs. We further investigated the effects of ceftriaxone (CEF), a beta-lactam antibiotic known to upregulate GLT-1, in this METH/ethanol co-abuse rat model. After 7 days of either ethanol (6 g/kg) or water oral gavage, Wistar rats received either saline or METH (10 mg/kg i.p. every 2 h * 4), followed by either saline or CEF (200 mg/kg) posttreatment. METH administered alone decreased GLT-1 expression in the nucleus accumbens (NAc) and prefrontal cortex (PFC) and increased body temperature, but did not reduce either xCT or GLAST expression in ethanol and water-pretreated rats. Interestingly, ethanol and METH were found to have an additive effect on the downregulation of GLT-1 expression in the NAc but not in the PFC. Moreover, ethanol alone caused GLT-1 downregulation in the NAc and elevated body temperature compared to control. Finally, CEF posttreatment significantly reversed METH-induced hyperthermia, restored GLT-1 expression, and increased xCT expression. These findings suggest the potential therapeutic role of CEF against METH- or ethanol/METH-induced hyperglutamatergic state and hyperthermia.

AB - The type 2 cannabinoid receptor (CB2) is a member of the endocannabinoid system and is known for its important role in (neuro)inflammation. A PET-imaging agent that allows in vivo visualization of CB2 expression may thus allow quantification of neuroinflammation. In this paper, we report the synthesis, radiosynthesis, biodistribution and in vitro evaluation of a carbon-11 ([11C]MA2) and a fluorine 18 ([18F]MA3) labeled analog of a highly potent N-arylamide oxadiazole CB2 agonist (EC50 = 0.015 nM). MA2 and MA3 behaved as potent CB2 agonist (EC50: 3 nM and 0.1 nM, respectively) and their in vitro binding affinity for hCB2 was found to be 87 nM and 0.8 nM, respectively. Also MA3 (substituted with a fluoro ethyl group) was found to have higher binding affinity and EC50 values when compared to the originally reported trifluoromethyl analog 12. [11C]MA2 and [18F]MA3 were successfully synthesized with good radiochemical yield, high radiochemical purity and high specific activity. In mice, both tracers were efficiently cleared from blood and all major organs by the hepatobiliary pathway and importantly these compounds showed high brain uptake. In conclusion, [11C]MA2 and [18F]MA3 are shown to be high potent CB2 agonists with good brain uptake, these favorable characteristics makes them potential PET probes for in vivo imaging of brain CB2 receptors. However, in view of its higher affinity and selectivity, further detailed evaluation of MA3 as a PET tracer for CB2 is warranted. PMID- 27713687 TI - Differential Effects of Toluene and Ethanol on Dopaminergic Neurons of the Ventral Tegmental Area. AB - Drugs of abuse increase the activity of dopaminergic neurons of the ventral tegmental area (VTA), and output from the VTA is critical for both natural and drug-induced reward and reinforcement. Ethanol and the abused inhalant toluene both enhance VTA neuronal firing, but the mechanisms of this effect is not fully known. In this study, we used extracellular recordings to compare the actions of toluene and ethanol on DA VTA neurons. Both ethanol and toluene increased the firing rate of DA neurons, although toluene was ~100 times more potent than ethanol. The mixed ion channel blocker quinine (100 MUM) blocked the increases in firing produced by ethanol and toluene, indicating some similarity in mechanisms of excitation. A mixture of antagonists of GABA and cholinergic receptors did not prevent toluene-induced or ethanol-induced excitation, and toluene-induced excitation was not altered by co-administration of ethanol, suggesting independent mechanisms of excitation for ethanol and toluene. Concurrent blockade of NMDA, AMPA, and metabotropic glutamate receptors enhanced the excitatory effect of toluene while having no significant effect on ethanol excitation. Nicotine increased firing of DA VTA neurons, and this was blocked by the nicotinic antagonist mecamylamine (1 MUM). Mecamylamine did not alter ethanol or toluene excitation of firing but the muscarinic antagonist atropine (5 MUM) or a combination of GABA antagonists (bicuculline and CGP35348, 10 MUM each) reduced toluene-induced excitation without affecting ethanol excitation. The Ih current blocker ZD7288 abolished the excitatory effect of toluene but unlike the block of ethanol excitation, the effect of ZD7288 was not reversed by the GIRK channel blocker barium, but was reversed by GABA antagonists. These results demonstrate that the excitatory effects of ethanol and toluene have some similarity, such as block by quinine and ZD7288, but also indicate that there are important differences between these two drugs in their modulation by glutamatergic, cholinergic, and GABAergic receptors. These findings provide important information regarding the actions of abused inhalants on central reward pathways, and suggest that regulation of the activation of central dopamine pathways by ethanol and toluene partially overlap. PMID- 27713689 TI - The Free Zinc Concentration in the Synaptic Cleft of Artificial Glycinergic Synapses Rises to At least 1 MUM. AB - Zn2+ is concentrated into presynaptic vesicles at many central synapses and is released into the synaptic cleft by nerve terminal stimulation. There is strong evidence that synaptically released Zn2+ modulates glutamatergic neurotransmission, although there is debate concerning the peak concentration it reaches in the synaptic cleft. Glycine receptors (GlyRs), which mediate inhibitory neurotransmission in the spinal cord and brainstem, are potentiated by low nanomolar Zn2+ and inhibited by micromolar Zn2+. Mutations that selectively ablate Zn2+ potentiation result in hyperekplexia phenotypes suggesting that Zn2+ is a physiological regulator of glycinergic neurotransmission. There is, however, little evidence that Zn2+ is stored presynaptically at glycinergic terminals and an alternate possibility is that GlyRs are modulated by constitutively bound Zn2+. We sought to estimate the peak Zn2+ concentration in the glycinergic synaptic cleft as a means of evaluating whether it is likely to be synaptically released. We employed 'artificial' synapses because they permit the insertion of engineered alpha1beta GlyRs with defined Zn2+ sensitivities into synapses. By comparing the effect of Zn2+ chelation on glycinergic IPSCs with the effects of defined Zn2+ and glycine concentrations applied rapidly to the same recombinant GlyRs in outside-out patches, we inferred that synaptic Zn2+ rises to at least 1 MUM following a single presynaptic stimulation. Moreover, using the fast, high affinity chelator, ZX1, we found no evidence for tonic Zn2+ bound constitutively to high affinity GlyR binding sites. We conclude that diffusible Zn2+ reaches 1 MUM or higher and is therefore likely to be phasically released in artificial glycinergic synapses. PMID- 27713688 TI - Connexins and Pannexins: New Insights into Microglial Functions and Dysfunctions. AB - Under physiological conditions, microglia adopt a resting phenotype associated with the production of anti-inflammatory and neurotrophic factors. In response to a wide variety of insults, these cells shift to an activated phenotype that is necessary for the proper restoration of brain homeostasis. However, when the intensity of a threat is relatively high, microglial activation worsens the progression of damage rather than providing protection, with potentially significant consequences for neuronal survival. Coordinated interactions among microglia and other brain cells, including astrocytes and neurons, are critical for the development of timely and optimal inflammatory responses in the brain parenchyma. Tissue synchronization is in part mediated by connexins and pannexins, which are protein families that form different plasma membrane channels to communicate with neighboring cells. Gap junction channels (which are exclusively formed by connexins in vertebrates) connect the cytoplasm of contacting cells to coordinate electrical and metabolic coupling. Hemichannels (HCs) and pannexons (which are formed by connexins and pannexins, respectively) communicate the intra- and extracellular compartments and serve as diffusion pathways for the exchange of ions and small molecules. In this review article, we discuss the available evidence concerning the functional expression and regulation of connexin- and pannexin-based channels in microglia and their contributions to microglial function and dysfunction. Specifically, we focus on the possible implications of these channels in microglia-to-microglia, microglia to-astrocyte and neuron-to-microglia interactions in the inflamed brain. PMID- 27713690 TI - The Endosome Localized Arf-GAP AGAP1 Modulates Dendritic Spine Morphology Downstream of the Neurodevelopmental Disorder Factor Dysbindin. AB - AGAP1 is an Arf1 GTPase activating protein that interacts with the vesicle associated protein complexes adaptor protein 3 (AP-3) and Biogenesis of Lysosome Related Organelles Complex-1 (BLOC-1). Overexpression of AGAP1 in non-neuronal cells results in an accumulation of endosomal cargoes, which suggests a role in endosome-dependent traffic. In addition, AGAP1 is a candidate susceptibility gene for two neurodevelopmental disorders, autism spectrum disorder (ASD) and schizophrenia (SZ); yet its localization and function in neurons have not been described. Here, we describe that AGAP1 localizes to axons, dendrites, dendritic spines and synapses, colocalizing preferentially with markers of early and recycling endosomes. Functional studies reveal overexpression and down-regulation of AGAP1 affects both neuronal endosomal trafficking and dendritic spine morphology, supporting a role for AGAP1 in the recycling endosomal trafficking involved in their morphogenesis. Finally, we determined the sensitivity of AGAP1 expression to mutations in the DTNBP1 gene, which is associated with neurodevelopmental disorder, and found that AGAP1 mRNA and protein levels are selectively reduced in the null allele of the mouse ortholog of DTNBP1. We postulate that endosomal trafficking contributes to the pathogenesis of neurodevelopmental disorders affecting dendritic spine morphology, and thus excitatory synapse structure and function. PMID- 27713692 TI - Determining Monkey Free Choice Long before the Choice Is Made: The Principal Role of Prefrontal Neurons Involved in Both Decision and Motor Processes. AB - When choices are made freely, they might emerge from pre-existing neural activity. However, whether neurons in the prefrontal cortex (PF) show this anticipatory effect and, if so, in which part of the process they are involved is still debated. To answer this question, we studied PF activity in monkeys while they performed a strategy task. In this task when the stimulus changed from the previous trial, the monkeys had to shift their response to one of two spatial goals, excluding the one that had been previously selected. Under this free choice condition, the prestimulus activity of the same neurons that are involved in decision and motor processes predicted future choices. These neurons developed the same goal preferences during the prestimulus presentation as they did later in the decision phase. In contrast, the same effect was not observed in motor only neurons and it was present but weaker in decision-only neurons. Overall, our results suggest that the PF neuronal activity predicts upcoming actions mainly through the decision-making network that integrate in time decision and motor task aspects. PMID- 27713693 TI - Patterns of Theta Activity in Limbic Anxiety Circuit Preceding Exploratory Behavior in Approach-Avoidance Conflict. AB - Theta oscillations within the hippocampus-amygdala-medial prefrontal cortex (HPC AMY-mPFC) circuit have been consistently implicated in the regulation of anxiety behaviors, including risk-assessment. To study if theta activity during risk assessment was correlated with exploratory behavior in an approach/avoidance paradigm we recorded simultaneous local field potentials from this circuit in rats exploring the elevated-plus maze (EPM). Opposing patterns of power variations in the ventral hippocampus (vHPC), basolateral amygdala (BLA), and prelimbic (PrL) mPFC, but not in the dorsal hippocampus (dHPC), during exploratory risk-assessment of the open arms preceded further exploration of the open arms or retreat back to the safer closed arms. The same patterns of theta power variations in the HPC-BLA-mPFC(PrL) circuit were also displayed by animals submitted to chronic unpredictable stress protocol known to induce an anxious state. Diverging patterns of vHPC-mPFC(PrL) theta coherence were also significantly correlated with forthcoming approach or avoidance behavior in the conflict situation in both controls and stressed animals; interestingly, vHPC BLA, and BLA-mPFC(PrL) theta coherence correlated with future behavior only in stressed animals, underlying the pivotal role of the amygdala on the stress response. PMID- 27713694 TI - Variation in the Oxytocin Receptor Gene Is Associated with Face Recognition and its Neural Correlates. AB - The ability to recognize faces is crucial for daily social interactions. Recent studies suggest that intranasal oxytocin administration improves social recognition in humans. Oxytocin signaling in the amygdala plays an essential role for social recognition in mice, and oxytocin administration has been shown to influence amygdala activity in humans. It is therefore possible that the effects of oxytocin on human social recognition depend on mechanisms that take place in the amygdala-a central region for memory processing also in humans. Variation in the gene encoding the oxytocin receptor (OXTR) has been associated with several aspects of social behavior. The present study examined the potential associations between nine OXTR polymorphisms, distributed across the gene, and the ability to recognize faces, as well as face-elicited amygdala activity measured by functional magnetic resonance imaging (fMRI) during incidental encoding of faces. The OXTR 3' polymorphism rs7632287, previously related to social bonding behavior and autism risk, was associated with participants' ability to recognize faces. Carriers of the GA genotype, associated with enhanced memory, displayed higher amygdala activity during face encoding compared to carriers of the GG genotype. In line with work in rodents, these findings suggest that, in humans, naturally occurring endogenous modulation of OXTR function affects social recognition through an amygdala-dependent mechanism. These findings contribute to the understanding of how oxytocin regulates human social behaviors. PMID- 27713695 TI - Are We Real When We Fake? Attunement to Object Weight in Natural and Pantomimed Grasping Movements. AB - Behavioral and neuropsychological studies suggest that real actions and pantomimed actions tap, at least in part, different neural systems. Inspired by studies showing weight-attunement in real grasps, here we asked whether (and to what extent) kinematics of pantomimed reach-to-grasp movement can reveal the weight of the pretended target. To address this question, we instructed participants (n = 15) either to grasp or pretend to grasp toward two differently weighted objects, i.e., a light object and heavy object. Using linear discriminant analysis, we then proceeded to classify the weight of the target - either real or pretended - on the basis of the recorded movement patterns. Classification analysis revealed that pantomimed reach-to-grasp movements retained information about object weight, although to a lesser extent than real grasp movements. These results are discussed in relation to the mechanisms underlying the control of real and pantomimed grasping movements. PMID- 27713691 TI - Characterizing and Modulating Brain Circuitry through Transcranial Magnetic Stimulation Combined with Electroencephalography. AB - The concurrent combination of transcranial magnetic stimulation (TMS) with electroencephalography (TMS-EEG) is a powerful technology for characterizing and modulating brain networks across developmental, behavioral, and disease states. Given the global initiatives in mapping the human brain, recognition of the utility of this technique is growing across neuroscience disciplines. Importantly, TMS-EEG offers translational biomarkers that can be applied in health and disease, across the lifespan, and in humans and animals, bridging the gap between animal models and human studies. However, to utilize the full potential of TMS-EEG methodology, standardization of TMS-EEG study protocols is needed. In this article, we review the principles of TMS-EEG methodology, factors impacting TMS-EEG outcome measures, and the techniques for preventing and correcting artifacts in TMS-EEG data. To promote the standardization of this technique, we provide comprehensive guides for designing TMS-EEG studies and conducting TMS-EEG experiments. We conclude by reviewing the application of TMS EEG in basic, cognitive and clinical neurosciences, and evaluate the potential of this emerging technology in brain research. PMID- 27713696 TI - Development of Effective Connectivity during Own- and Other-Race Face Processing: A Granger Causality Analysis. AB - Numerous developmental studies have suggested that other-race effect (ORE) in face recognition emerges as early as in infancy and develops steadily throughout childhood. However, there is very limited research on the neural mechanisms underlying this developmental ORE. The present study used Granger causality analysis (GCA) to examine the development of children's cortical networks in processing own- and other-race faces. Children were between 3 and 13 years. An old-new paradigm was used to assess their own- and other-race face recognition with ETG-4000 (Hitachi Medical Co., Japan) acquiring functional near infrared spectroscopy (fNIRS) data. After preprocessing, for each participant and under each face condition, we obtained the causal map by calculating the weights of causal relations between the time courses of [oxy-Hb] of each pair of channels using GCA. To investigate further the differential causal connectivity for own race faces and other-race faces at the group level, a repeated measure analysis of variance (ANOVA) was performed on the GCA weights for each pair of channels with the face race task (own-race face vs. other-race face) as the within-subject variable and the age as a between-subject factor (continuous variable). We found an age-related increase in functional connectivity, paralleling a similar age related improvement in behavioral face processing ability. More importantly, we found that the significant differences in neural functional connectivity between the recognition of own-race faces and that of other-race faces were modulated by age. Thus, like the behavioral ORE, the neural ORE emerges early and undergoes a protracted developmental course. PMID- 27713698 TI - Stress Assessment by Prefrontal Relative Gamma. AB - Stress assessment has been under study in the last years. Both biochemical and physiological markers have been used to measure stress level. In neuroscience, several studies have related modification of stress level to brain activity changes in limbic system and frontal regions, by using non-invasive techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG). In particular, previous studies suggested that the exhibition or inhibition of certain brain rhythms in frontal cortical areas indicates stress. However, there is no established marker to measure stress level by EEG. In this work, we aimed to prove the usefulness of the prefrontal relative gamma power (RG) for stress assessment. We conducted a study based on stress and relaxation periods. Six healthy subjects performed the Montreal Imaging Stress Task (MIST) followed by a stay within a relaxation room while EEG and electrocardiographic signals were recorded. Our results showed that the prefrontal RG correlated with the expected stress level and with the heart rate (HR; 0.8). In addition, the difference in prefrontal RG between time periods of different stress level was statistically significant (p < 0.01). Moreover, the RG was more discriminative between stress levels than alpha asymmetry, theta, alpha, beta, and gamma power in prefrontal cortex. We propose the prefrontal RG as a marker for stress assessment. Compared with other established markers such as the HR or the cortisol, it has higher temporal resolution. Additionally, it needs few electrodes located at non-hairy head positions, thus facilitating the use of non invasive dry wearable real-time devices for ubiquitous assessment of stress. PMID- 27713697 TI - Does the Cerebral Cortex Exploit High-Dimensional, Non-linear Dynamics for Information Processing? AB - The discovery of stimulus induced synchronization in the visual cortex suggested the possibility that the relations among low-level stimulus features are encoded by the temporal relationship between neuronal discharges. In this framework, temporal coherence is considered a signature of perceptual grouping. This insight triggered a large number of experimental studies which sought to investigate the relationship between temporal coordination and cognitive functions. While some core predictions derived from the initial hypothesis were confirmed, these studies, also revealed a rich dynamical landscape beyond simple coherence whose role in signal processing is still poorly understood. In this paper, a framework is presented which establishes links between the various manifestations of cortical dynamics by assigning specific coding functions to low-dimensional dynamic features such as synchronized oscillations and phase shifts on the one hand and high-dimensional non-linear, non-stationary dynamics on the other. The data serving as basis for this synthetic approach have been obtained with chronic multisite recordings from the visual cortex of anesthetized cats and from monkeys trained to solve cognitive tasks. It is proposed that the low-dimensional dynamics characterized by synchronized oscillations and large-scale correlations are substates that represent the results of computations performed in the high dimensional state-space provided by recurrently coupled networks. PMID- 27713699 TI - Plant Alkaloids as Antiplatelet Agent: Drugs of the Future in the Light of Recent Developments. AB - An alkaloid is a class of naturally occurring organic nitrogen-containing compounds that are frequently found in the plant kingdom. Many alkaloids are valuable medicinal agents that can be utilized to treat various diseases including malaria, diabetics, cancer, cardiac dysfunction etc. Similarly, platelet aggregation beyond the purpose of homeostasis is the underlying cause of blood clotting related diseases. This review presents a thorough understanding of alkaloids as antiplatelet agents with a possible mechanism of action based on the literature of the last decade. In addition, this review will address the antiplatelet activity of alkaloids and their medicinal usage as potent antiplatelet agents with a description of structural relationship activity and possible lead compounds for future drug discovery. PMID- 27713701 TI - Improvements in Cycling Time Trial Performance Are Not Sustained Following the Acute Provision of Challenging and Deceptive Feedback. AB - The provision of performance-related feedback during exercise is acknowledged as an influential external cue used to inform pacing decisions. The provision of this feedback in a challenging or deceptive context allows research to explore how feedback can be used to improve performance and influence perceptual responses. However, the effects of deception on both acute and residual responses have yet to be explored, despite potential application for performance enhancement. Therefore, this study investigated the effects of challenging and deceptive feedback on perceptual responses and performance in self-paced cycling time trials (TT) and explored whether changes in performance are sustained in a subsequent TT following the disclosure of the deception. Seventeen trained male cyclists were assigned to either an accurate or deceptive feedback group and performed four 16.1 km cycling TTs; (1 and 2) ride-alone baseline TTs where a fastest baseline (FBL) performance was identified, (3) a TT against a virtual avatar representing 102% of their FBL performance (PACER), and (4) a subsequent ride-alone TT (SUB). The deception group, however, were initially informed that the avatar accurately represented their FBL, but prior to SUB were correctly informed of the nature of the avatar. Affect, self-efficacy and RPE were measured every quartile. Both groups performed PACER faster than FBL and SUB (p < 0.05) and experienced lower affect (p = 0.016), lower self-efficacy (p = 0.011), and higher RPE (p < 0.001) in PACER than FBL. No significant differences were found between FBL and SUB for any variable. The presence of the pacer rather than the manipulation of performance beliefs acutely facilitates TT performance and perceptual responses. Revealing that athletes' performance beliefs were falsely negative due to deceptive feedback provision has no effect on subsequent perceptions or performance. A single experiential exposure may not be sufficient to produce meaningful changes in the performance beliefs of trained individuals beyond the acute setting. PMID- 27713702 TI - Population Dynamics and Flight Phenology Model of Codling Moth Differ between Commercial and Abandoned Apple Orchard Ecosystems. AB - Apple orchard management practices may affect development and phenology of arthropod pests, such as the codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), which is a serious internal fruit-feeding pest of apples worldwide. Estimating population dynamics and accurately predicting the timing of CM development and phenology events (for instance, adult flight, and egg-hatch) allows growers to understand and control local populations of CM. Studies were conducted to compare the CM flight phenology in commercial and abandoned apple orchard ecosystems using a logistic function model based on degree-days accumulation. The flight models for these orchards were derived from the cumulative percent moth capture using two types of commercially available CM lure baited traps. Models from both types of orchards were also compared to another model known as PETE (prediction extension timing estimator) that was developed in 1970s to predict life cycle events for many fruit pests including CM across different fruit growing regions of the United States. We found that the flight phenology of CM was significantly different in commercial and abandoned orchards. CM male flight patterns for first and second generations as predicted by the constrained and unconstrained PCM (Pennsylvania Codling Moth) models in commercial and abandoned orchards were different than the flight patterns predicted by the currently used CM model (i.e., PETE model). In commercial orchards, during the first and second generations, the PCM unconstrained model predicted delays in moth emergence compared to current model. In addition, the flight patterns of females were different between commercial and abandoned orchards. Such differences in CM flight phenology between commercial and abandoned orchard ecosystems suggest potential impact of orchard environment and crop management practices on CM biology. PMID- 27713700 TI - Drug Discovery via Human-Derived Stem Cell Organoids. AB - Patient-derived cell lines and animal models have proven invaluable for the understanding of human intestinal diseases and for drug development although both inherently comprise disadvantages and caveats. Many genetically determined intestinal diseases occur in specific tissue microenvironments that are not adequately modeled by monolayer cell culture. Likewise, animal models incompletely recapitulate the complex pathologies of intestinal diseases of humans and fall short in predicting the effects of candidate drugs. Patient derived stem cell organoids are new and effective models for the development of novel targeted therapies. With the use of intestinal organoids from patients with inherited diseases, the potency and toxicity of drug candidates can be evaluated better. Moreover, owing to the novel clustered regularly interspaced short palindromic repeats/CRISPR-associated protein-9 genome-editing technologies, researchers can use organoids to precisely modulate human genetic status and identify pathogenesis-related genes of intestinal diseases. Therefore, here we discuss how patient-derived organoids should be grown and how advanced genome editing tools may be applied to research on modeling of cancer and infectious diseases. We also highlight practical applications of organoids ranging from basic studies to drug screening and precision medicine. PMID- 27713703 TI - Gene Expression in Response to Exercise in Patients with Chronic Fatigue Syndrome: A Pilot Study. AB - Chronic fatigue syndrome (CFS) is a debilitating disorder of unknown pathogenesis, characterized by fatigue, which is exacerbated after minimal exercise. We examined the effect of a single bout of aerobic exercise on leucocyte mRNA expression of genes putatively linked to exaggerated afferent signaling as an under-pinning of the fatigue state. A carefully-characterized sample of patients with CFS (N = 10) and healthy matched control participants (N = 12) were included. Participant ratings of fatigue and other symptoms, as well as blood samples, were obtained at baseline, and five other time-points up to 72 h after 25 min of moderate-intensity cycling exercise. Leucocyte mRNA of 19 metabolite-sensing, adrenergic, immune, and neurotransmission genes was examined using quantitative polymerase chain reaction. Patients with CFS reported substantial fatigue, functional impairment, and poor sleep at baseline (all p < 0.02), and exercise immediately induced worsened patients' fatigue (effect size, ES = 1.17). There were no significant changes in gene expression after exercise and patients did not differ from control participants at any time point. Higher levels of expression of ficolin (FCN1) and a purinergic receptor (P2RX4) in patients with CFS were found when all time points were combined. Patients with CFS did not show significant exercise-induced changes in leucocyte mRNA of 19 metabolite-sensing, adrenergic, immune and neurotransmission genes despite a prominent exacerbation of fatigue.

PMID- 27713706 TI - Detecting Superior Face Recognition Skills in a Large Sample of Young British Adults. AB - The Cambridge Face Memory Test Long Form (CFMT+) and Cambridge Face Perception Test (CFPT) are typically used to assess the face processing ability of individuals who believe they have superior face recognition skills. Previous large-scale studies have presented norms for the CFPT but not the CFMT+. However, previous research has also highlighted the necessity for establishing country specific norms for these tests, indicating that norming data is required for both tests using young British adults. The current study addressed this issue in 254 British participants. In addition to providing the first norm for performance on the CFMT+ in any large sample, we also report the first UK specific cut-off for superior face recognition on the CFPT. Further analyses identified a small advantage for females on both tests, and only small associations between objective face recognition skills and self-report measures. A secondary aim of the study was to examine the relationship between trait or social anxiety and face processing ability, and no associations were noted. The implications of these findings for the classification of super-recognizers are discussed. PMID- 27713705 TI - Pacemaking Property of RVLM Presympathetic Neurons. AB - Despite several studies describing the electrophysiological properties of RVLM presympathetic neurons, there is no consensus in the literature about their pacemaking property, mainly due to different experimental approaches used for recordings of neuronal intrinsic properties. In this review we are presenting a historical retrospective about the pioneering studies and their controversies on the intrinsic electrophysiological property of auto-depolarization of these cells in conjunction with recent studies from our laboratory documenting that RVLM presympathetic neurons present pacemaking capacity. We also discuss whether increased sympathetic activity observed in animal models of neurogenic hypertension (CIH and SHR) are dependent on changes in the intrinsic electrophysiological properties of these cells or due to changes in modulatory inputs from neurons of the respiratory network. We also highlight the key role of INaP as the major current contributing to the pacemaking property of RVLM presympathetic neurons. PMID- 27713707 TI - How to Measure the Intervention Process? An Assessment of Qualitative and Quantitative Approaches to Data Collection in the Process Evaluation of Organizational Interventions. AB - Organizational interventions aiming at improving employee health and wellbeing have proven to be challenging to evaluate. To analyze intervention processes two methodological approaches have widely been used: quantitative (often questionnaire data), or qualitative (often interviews). Both methods are established tools, but their distinct epistemological properties enable them to illuminate different aspects of organizational interventions. In this paper, we use the quantitative and qualitative process data from an organizational intervention conducted in a national postal service, where the Intervention Process Measure questionnaire (N = 285) as well as an extensive interview study (N = 50) were used. We analyze what type of knowledge about intervention processes these two methodologies provide and discuss strengths and weaknesses as well as potentials for mixed methods evaluation methodologies. PMID- 27713708 TI - Implications of "Too Good to Be True" for Replication, Theoretical Claims, and Experimental Design: An Example Using Prominent Studies of Racial Bias. AB - In response to concerns about the validity of empirical findings in psychology, some scientists use replication studies as a way to validate good science and to identify poor science. Such efforts are resource intensive and are sometimes controversial (with accusations of researcher incompetence) when a replication fails to show a previous result. An alternative approach is to examine the statistical properties of the reported literature to identify some cases of poor science. This review discusses some details of this process for prominent findings about racial bias, where a set of studies seems "too good to be true." This kind of analysis is based on the original studies, so it avoids criticism from the original authors about the validity of replication studies. The analysis is also much easier to perform than a new empirical study. A variation of the analysis can also be used to explore whether it makes sense to run a replication study. As demonstrated here, there are situations where the existing data suggest that a direct replication of a set of studies is not worth the effort. Such a conclusion should motivate scientists to generate alternative experimental designs that better test theoretical ideas.

AB - Objective: The aim of the present study was to analyze the effects of a mindfulness training psycho-educative program on impulsivity and aggression levels in a sample of high school students. Methods: A randomized controlled trial with pre-test-post-test measurements was applied to an experimental group and a control group (waiting list). The Barratt Impulsivity Scale (BIS-11) Patton et al. (1995) and the Aggression Questionnaire (Buss and Perry, 1992) were used. Results: Statistical analyses showed a significant decrease in the levels of impulsivity and aggressiveness in the experimental group compared with the control group. These results have important implications for improving the level of academic engagement and self-efficacy of students and for reducing school failure. Conclusion: This is one of the first studies showing the effectiveness of mindfulness training at reducing impulsive and aggressive behaviors in the classroom. The efficacy of mindfulness-based programs is emphasized. PMID- 27713710 TI - Cognitive Reflection, Decision Biases, and Response Times. AB - We present novel evidence on response times and personality traits in standard questions from the decision-making literature where responses are relatively slow (medians around half a minute or above). To this end, we measured response times in a number of incentivized, framed items (decisions from description) including the Cognitive Reflection Test, two additional questions following the same logic, and a number of classic questions used to study decision biases in probability judgments (base-rate neglect, the conjunction fallacy, and the ratio bias). All questions create a conflict between an intuitive process and more deliberative thinking. For each item, we then created a non-conflict version by either making the intuitive impulse correct (resulting in an alignment question), shutting it down (creating a neutral question), or making it dominant (creating a heuristic question). For CRT questions, the differences in response times are as predicted by dual-process theories, with alignment and heuristic variants leading to faster responses and neutral questions to slower responses than the original, conflict questions. For decision biases (where responses are slower), evidence is mixed. To explore the possible influence of personality factors on both choices and response times, we used standard personality scales including the Rational Experiential Inventory and the Big Five, and used them as controls in regression analysis. PMID- 27713711 TI - Work Characteristics and Occupational Well-Being: The Role of Age. AB - Based on a lifespan perspective on work design, person-environment interaction and fit theories, models of successful aging at work, and role theory, we review research on the role of worker age in relationships between work characteristics and occupational well-being. We first focus on interaction effects of work characteristics and age on occupational well-being. Research has found that age can moderate associations between work characteristics and occupational well being indicators, and that work characteristics can moderate associations between age and occupational well-being indicators. Next, we describe research showing that work characteristics can mediate associations between age and occupational well-being indicators. The relationships of age with specific work characteristics and occupational well-being indicators can be linear or non linear. We conclude our literature review by discussing implications for future research. PMID- 27713714 TI - Editorial: When (and How) Is Theory of Mind Useful? Evidence from Life-Span Research. PMID- 27713713 TI - Isochronous Sequential Presentation Helps Children Orient Their Attention in Time. AB - Knowing when an event is likely to occur allows attentional resources to be oriented toward that moment in time, enhancing processing of the event. We previously found that children (mean age 11 years) are unable to use endogenous temporal cues to orient attention in time, despite being able to use endogenous spatial cues (arrows) to orient attention in space. Arrow cues, however, may have proved beneficial by engaging exogenous (automatic), as well as endogenous (voluntary), orienting mechanisms. We therefore conducted two studies in which the exogenous properties of visual temporal cues were increased, to examine whether this helped children orient their attention in time. In the first study, the location of an imperative target was predicted by the direction of a left or right spatial arrow cue while its onset was predicted by the relative duration of a short or long temporal cue. To minimize the influence of rhythmic entrainment in the temporal condition, the foreperiod (500 ms/1100 ms) was deliberately chosen so as not to precisely match the duration of the temporal cue (100 ms/400 ms). Targets appeared either at cued locations/onset times (valid trials) or at unexpected locations/onset times (invalid trials). Adults' response times were significantly slower for invalid versus valid trials, in both spatial and temporal domains. Despite being slowed by invalid spatial cues, children (mean age 10.7 years) were unperturbed by invalid temporal cues, suggesting that these duration-based temporal cues did not help them orient attention in time. In the second study, we enhanced the exogenous properties of temporal cues further, by presenting multiple temporal cues in an isochronous (rhythmic) sequence. Again, to minimize automatic entrainment, target onset did not match the isochronous interval. Children (mean age 11.4 years), as well as adults, were now significantly slowed by invalid cues in both the temporal and spatial dimension. The sequential, as opposed to single, presentation of temporal cues therefore helped children to orient their attention in time. We suggest that the exogenous properties of sequential presentation provide a temporal scaffold that supports the additional attentional and mnemonic requirements of temporal, as compared to spatial, processing. PMID- 27713712 TI - Vowels and Consonants in the Brain: Evidence from Magnetoencephalographic Studies on the N1m in Normal-Hearing Listeners. AB - Speech sound perception is one of the most fascinating tasks performed by the human brain. It involves a mapping from continuous acoustic waveforms onto the discrete phonological units computed to store words in the mental lexicon. In this article, we review the magnetoencephalographic studies that have explored the timing and morphology of the N1m component to investigate how vowels and consonants are computed and represented within the auditory cortex. The neurons that are involved in the N1m act to construct a sensory memory of the stimulus due to spatially and temporally distributed activation patterns within the auditory cortex. Indeed, localization of auditory fields maps in animals and humans suggested two levels of sound coding, a tonotopy dimension for spectral properties and a tonochrony dimension for temporal properties of sounds. When the stimulus is a complex speech sound, tonotopy and tonochrony data may give important information to assess whether the speech sound parsing and decoding are generated by pure bottom-up reflection of acoustic differences or whether they are additionally affected by top-down processes related to phonological categories. Hints supporting pure bottom-up processing coexist with hints supporting top-down abstract phoneme representation. Actually, N1m data (amplitude, latency, source generators, and hemispheric distribution) are limited and do not help to disentangle the issue. The nature of these limitations is discussed. Moreover, neurophysiological studies on animals and neuroimaging studies on humans have been taken into consideration. We compare also the N1m findings with the investigation of the magnetic mismatch negativity (MMNm) component and with the analogous electrical components, the N1 and the MMN. We conclude that N1 seems more sensitive to capture lateralization and hierarchical processes than N1m, although the data are very preliminary. Finally, we suggest that MEG data should be integrated with EEG data in the light of the neural oscillations framework and we propose some concerns that should be addressed by future investigations if we want to closely line up language research with issues at the core of the functional brain mechanisms.

AB - Executive function deficits have been linked to attention deficit hyperactivity disorder (ADHD), but it has been theorized that the symptom inattention is specifically related to problems with complex verbal working memory (WM). Using the Conners Adult ADHD rating scale, adults aged 18-35 were assessed for ADHD symptoms, and completed tasks designed to tap verbal and spatial aspects of WM (Experiment 1). Results showed that high inattention predicted poor performance on both simple and complex verbal WM measures. Results relating to spatial WM were inconclusive. In a follow up experiment based on the theory that those with inattention have problems receiving verbal instructions, a measure of goal neglect assessing integration of information into a task model in WM was employed (Experiment 2). Results showed that high inattention uniquely predicted performance on this task, representing the first reported association between inattention and the phenomenon of goal neglect. The results from both experiments lend support to the WM theory of inattention. PMID- 27713717 TI - Just Google It: Young Children's Preferences for Touchscreens versus Books in Hypothetical Learning Tasks. AB - Children today regularly interact with touchscreen devices (Rideout, 2013) and thousands of "educational" mobile applications are marketed to them (Shuler, 2012). Understanding children's own ideas about optimal learning has important implications for education, which is being transformed by electronic mobile devices, yet we know little about how children think about such devices, including what children think touchscreens are useful for. Based on a prior result that children prefer a book over a touchscreen for learning about dogs, the present study explored how children view touchscreens versus books for learning an array of different types of information. Seventy children ages 3-6 were presented with six different topics (cooking, today's weather, trees, vacuums, Virginia, and yesterday's football game) and chose whether a book or a touchscreen device would be best to use to learn about each topic. Some of this information was time-sensitive, like the current weather; we predicted that children would prefer a touchscreen for time-sensitive information. In addition, each child's parent was surveyed about the child's use of books and touchscreens for educational purposes, both at home and in school. Results indicated that younger children had no preference between books and touchscreen devices across learning tasks. However, 6-year-olds were significantly more likely to choose the touchscreen for several topics. Surprisingly, 6-year-olds chose a touchscreen device to learn about time-sensitive weather conditions, but not yesterday's football. Children's choices were not associated with their use of books and touchscreens at home and school. PMID- 27713718 TI - Processing Metrical Information in Silent Reading: An ERP Study. AB - Listeners are sensitive to the metric structure of words, i.e., an alternating pattern of stressed and unstressed syllables, in auditory speech processing: Event-related potentials recorded as participants listen to a sequence of words with a consistent metrical pattern, e.g., a series of trochaic words, suggest that participants register words metrically incongruent with the preceding sequence. Here we examine whether the processing of individual words in silent reading is similarly impacted by rhythmic properties of the surrounding context. We recorded participants' EEG as they read lists of either three trochaic or iambic disyllabic words followed by a target word that was either congruent or incongruent with the preceding metric pattern. Event-Related Potentials (ERPs) to targets were modulated by an interaction between metrical structure (iambic vs. trochaic) and congruence: for iambs, more positive ERPs were observed in the incongruent than congruent condition 250-400 ms and 400-600 ms post-stimulus, whereas no reliable impact of congruence was found for trochees. We suggest that when iambs are in an incongruent context, i.e., preceded by trochees, the context contains the metrical structure that is more typical in participants' native language which facilitates processing relative to when they are presented in a congruent context, containing the less typical, i.e., iambic, metrical structure. The results provide evidence that comprehenders are sensitive to the prosodic properties of the context even in silent reading, such that this sensitivity impacts lexico-semantic processing of individual words. PMID- 27713719 TI - Lay Explanatory Models of Depression and Preferred Coping Strategies among Somali Refugees in Norway. A Mixed-Method Study. AB - Objective: Refugees are at high risk of experiencing mental health problems due to trauma in their pasts and to acculturation stress as they settle in a new country. To develop efficient health services that meet the needs of refugees from different regions, an understanding is required of how they make sense of and prefer to cope with mental health problems. This study aims to investigate lay explanatory models of depression and preferred coping strategies among Somali refugees in Norway. Methods: The study used a mixed-method design with a vignette describing a moderately depressed person based on ICD-10 criteria. Firstly, a survey study was performed among Somali refugees (n = 101). Respondents were asked to give advice to the vignette character and complete the Cross-Cultural Depression Coping Inventory and the General Help-Seeking Questionnaire. Secondly, focus group interviews (n = 10) were conducted separately with males and females to examine the relationship between the explanatory models of depression and the preferred coping strategies. Results: The participants showed a strong preference for coping with depression by religious practices and reliance on family, friends, and their ethnic/religious community, rather than by seeking professional treatment from public health services (e.g., medical doctors, psychologists). Depressive symptoms were conceptualized as a problem related to cognition (thinking too much) and emotion (sadness), but not to biological mechanisms, and they were thought to result from spiritual possession, stress as a result of social isolation, and/or past trauma. Independently of time in exile, the participants showed a strong identification with their ethnic origin and associated values. Because participants emphasized the need to obey and follow the views of elders, fathers, and spiritual leaders, these authorities seemed to be "gatekeepers" for access to mental health services. Conclusion: The results highlight that mental health programs for Somali refugees should actively involve the ethnic community, including spiritual leaders, in order to reach patients in need and to foster treatment compliance. PMID- 27713720 TI - Romantic Love vs. Drug Addiction May Inspire a New Treatment for Addiction. AB - Drug addiction is a complex neurological dysfunction induced by recurring drug intoxication. Strategies to prevent and treat drug addiction constitute a topic of research interest. Early-stage romantic love is characterized by some characteristics of addiction, which gradually disappear as the love relationship progresses. Therefore, comparison of the concordance and discordance between romantic love and drug addiction may elucidate potential treatments for addiction. This focused review uses the evidences from our recent studies to compare the neural alterations between romantic love and drug addiction, moreover we also compare the behavioral and neurochemical alterations between romantic love and drug addiction. From the behavioral comparisons we find that there are many similarities between the early stage of romantic love and drug addiction, and this stage romantic love is considered as a behavioral addiction, while significant differences exist between the later stage of romantic love and drug addiction, and this stage of romantic love eventually developed into a prosocial behavior. The neuroimaging comparisons suggest that romantic love and drug addiction both display the functional enhancement in reward and emotion regulation network. Except the similar neural changes, romantic love display special function enhancement in social cognition network, while drug addiction display special dysfunction in cognitive control network. The neurochemical comparisons show that there are many similarities in the dopamine (DA) system, while significant differences in oxytocin (OT) system for romantic love and drug addiction. These findings indicate that the functional alterations in reward and emotion regulation network and the DA system may be the neurophysiological basis of romantic love as a behavioral addiction, and the functional alterations in social cognition network and the OT system may be the neurophysiological basis of romantic love as a prosocial behavior. It seems that the OT system is a critical factor for the development of addiction. So we then discuss strategies to treat drug addiction with OT, and suggest that future research should further investigate OT system interventions aiming to improve cognitive control and/or social cognition functions, in order to develop strategies designed to more effectively treat drug addiction. PMID- 27713721 TI - Modulating the Activity of Ventromedial Prefrontal Cortex by Anodal tDCS Enhances the Trustee's Repayment through Altruism. AB - Trust and trustworthiness are essential to an efficient economy and play crucial roles in social life. Previous evidence from behavioral experiments has revealed that the trustworthiness of individuals is closely related with their altruistic preference. It has been demonstrated that the ventromedial prefrontal cortex (vmPFC) is associated with decisions involving trustworthiness. Moreover, vmPFC lesion patients showed less trustworthiness and altruism than control subjects, indicating the indispensable role of this specific brain area in human social interactions. However, the causal relationship between this neural area and trustworthiness, as well as altruism, has not been fully revealed. The potential neural basis behind the behavior of trustees' repayment has also seldom been discussed. In the present study, we aimed to provide evidence of a direct link between the neural and behavioral results through the application of transcranial direct current stimulation (tDCS) over the vmPFC of our participants. We found that activating the vmPFC could promote both the trustworthiness and altruism of our participants. We also show that enhancing the excitability of the vmPFC using tDCS increased the trustworthiness of the participants, and this promoting effect might be attributable to the enhancement of individuals' altruistic preference. In addition, we revealed that the enhancing effect in trustworthiness and altruism might be specific to the activation of the vmPFC by applying tDCS over another brain region within the prefrontal cortex as a control site. Crucially, our findings provide direct evidence supporting the critical role of the vmPFC in cooperative behaviors in economic interactions, especially the trustees' repayment in the trust game and the dictators' altruistic transfer in the dictator game. PMID- 27713722 TI - Episodic Short-Term Recognition Requires Encoding into Visual Working Memory: Evidence from Probe Recognition after Letter Report. AB - Human vision is organized in discrete processing episodes (e.g., eye fixations or task-steps). Object information must be transmitted across episodes to enable episodic short-term recognition: recognizing whether a current object has been seen in a previous episode. We ask whether episodic short-term recognition presupposes that objects have been encoded into capacity-limited visual working memory (VWM), which retains visual information for report. Alternatively, it could rely on the activation of visual features or categories that occurs before encoding into VWM. We assessed the dependence of episodic short-term recognition on VWM by a new paradigm combining letter report and probe recognition. Participants viewed displays of 10 letters and reported as many as possible after a retention interval (whole report). Next, participants viewed a probe letter and indicated whether it had been one of the 10 letters (probe recognition). In Experiment 1, probe recognition was more accurate for letters that had been encoded into VWM (reported letters) compared with non-encoded letters (non reported letters). Interestingly, those letters that participants reported in their whole report had been near to one another within the letter displays. This suggests that the encoding into VWM proceeded in a spatially clustered manner. In Experiment 2, participants reported only one of 10 letters (partial report) and probes either referred to this letter, to letters that had been near to it, or far from it. Probe recognition was more accurate for near than for far letters, although none of these letters had to be reported. These findings indicate that episodic short-term recognition is constrained to a small number of simultaneously presented objects that have been encoded into VWM. PMID- 27713723 TI - A Tutorial on Hunting Statistical Significance by Chasing N. AB - There is increasing concern about the replicability of studies in psychology and cognitive neuroscience. Hidden data dredging (also called p-hacking) is a major contributor to this crisis because it substantially increases Type I error resulting in a much larger proportion of false positive findings than the usually expected 5%. In order to build better intuition to avoid, detect and criticize some typical problems, here I systematically illustrate the large impact of some easy to implement and so, perhaps frequent data dredging techniques on boosting false positive findings. I illustrate several forms of two special cases of data dredging. First, researchers may violate the data collection stopping rules of null hypothesis significance testing by repeatedly checking for statistical significance with various numbers of participants. Second, researchers may group participants post hoc along potential but unplanned independent grouping variables. The first approach 'hacks' the number of participants in studies, the second approach 'hacks' the number of variables in the analysis. I demonstrate the high amount of false positive findings generated by these techniques with data from true null distributions. I also illustrate that it is extremely easy to introduce strong bias into data by very mild selection and re-testing. Similar, usually undocumented data dredging steps can easily lead to having 20-50%, or more false positives. PMID- 27713724 TI - Paranoia as an Antecedent and Consequence of Getting Ahead in Organizations: Time Lagged Effects Between Paranoid Cognitions, Self-Monitoring, and Changes in Span of Control. AB - A 6-month, time-lagged online survey among 441 employees in diverse industries was conducted to investigate the role paranoia plays as an antecedent and as a consequence of advancement in organizations. The background of the study is the argument that it requires active social sense-making and behavioral adaptability to advance in organizations. The present paper thus explores the extent to which employees' paranoid cognitions-representative of a heightened albeit suspicious sense-making and behavioral adaptability-link with their advancement in organizations (operationalized as changes in afforded span of control), both as an antecedent and an outcome. Following the strategy to illuminate the process by interaction analysis, both conditions (antecedent and outcome) are examined in interaction with employees' self-monitoring, which is considered representative of a heightened but healthy sense-making and behavioral adaptability. Results support the expected interference interaction between paranoid cognitions and self-monitoring in that each can to some degree compensate for the other in explaining employees' organizational advancement. Reversely, changes in span of control also affected paranoid cognitions. In particular, low self-monitors, i.e., those low in adaptive sense-making, reacted with heightened paranoid cognitions when demoted. In effect, the present study is thus the first to empirically support that paranoid cognitions can be a consequence but also a prerequisite for getting ahead in organizations. Practical advice should, however, be suspended until it is better understood whether and under what circumstances paranoia may relate not only to personally getting ahead but also to an increased effectiveness for the benefit of the organization. PMID- 27713725 TI - A Price Paid for Our Internal Strife: Escalated Intragroup Aggression and the Evolution of Ingroup Derogation. AB - From evolutionary reasoning, we derived a novel hypothesis that ingroup derogation is an adaptation to a special ecological condition in which the greater threat of aggression is incurred by ingroup members. This hypothesis was tested and supported across five studies. Specifically, the computational modeling found that ingroup derogation could easily evolve if the chance of death incurred by intragroup conflicts was no less than 10%. Further behavioral experiments on Chinese participants showed that the ingroup derogation mechanism responded to heuristic social category cues and it responded more strongly when participants subjectively felt more vulnerable to interpersonal aggression, or when there were contextual cues of aggression in the immediate environment. Additional results showed that Chinese participants responded more strongly to aggression cues originating from ingroup members and that they endorsed more ingroup derogation attitudes even when the ingroup and outgroup members were both displaying cues of aggression. In addition, the results also revealed that the Chinese participants perceived more intentions of aggression from ingroup members than from outgroup members even in the absence of any clear signs of those intentions, and such a bias was positively correlated with ingroup derogation attitudes. Taken together, these results suggest that ingroup derogation is related to the evolved response of intragroup aggression management system. PMID- 27713726 TI - Optimization of Xylanase Production through Response Surface Methodology by Fusarium sp. BVKT R2 Isolated from Forest Soil and Its Application in Saccharification. AB - Xylanses are hydrolytic enzymes with wide applications in several industries like biofuels, paper and pulp, deinking, food, and feed. The present study was aimed at hitting at high yield xylanase producing fungi from natural resources. Two highest xylanase producing fungal isolates-Q12 and L1 were picked from collection of 450 fungal cultures for the utilization of xylan. These fungal isolates-Q12 and L1 were identified basing on ITS gene sequencing analysis as Fusarium sp. BVKT R2 (KT119615) and Fusarium strain BRR R6 (KT119619), respectively with construction of phylogenetic trees. Fusarium sp. BVKT R2 was further optimized for maximum xylanase production and the interaction effects between variables on production of xylanase were studied through response surface methodology. The optimal conditions for maximal production of xylanase were sorbitol 1.5%, yeast extract 1.5%, pH of 5.0, Temperature of 32.5 degrees C, and agitation of 175 rpm. Under optimal conditions, the yields of xylanase production by Fusarium sp. BVKT R2 was as high as 4560 U/ml in SmF. Incubation of different lignocellulosic biomasses with crude enzyme of Fusarium sp. BVKT R2 at 37 degrees C for 72 h could achieve about 45% saccharification. The results suggest that Fusarium sp. BVKT R2 has potential applications in saccharification process of biomass. PMID- 27713727 TI - Microbial Community Structure of Subglacial Lake Whillans, West Antarctica. AB - Subglacial Lake Whillans (SLW) is located beneath ~800 m of ice on the Whillans Ice Stream in West Antarctica and was sampled in January of 2013, providing the first opportunity to directly examine water and sediments from an Antarctic subglacial lake. To minimize the introduction of surface contaminants to SLW during its exploration, an access borehole was created using a microbiologically clean hot water drill designed to reduce the number and viability of microorganisms in the drilling water. Analysis of 16S rRNA genes (rDNA) amplified from samples of the drilling and borehole water allowed an evaluation of the efficacy of this approach and enabled a confident assessment of the SLW ecosystem inhabitants. Based on an analysis of 16S rDNA and rRNA (i.e., reverse-transcribed rRNA molecules) data, the SLW community was found to be bacterially dominated and compositionally distinct from the assemblages identified in the drill system. The abundance of bacteria (e.g., Candidatus Nitrotoga, Sideroxydans, Thiobacillus, and Albidiferax) and archaea (Candidatus Nitrosoarchaeum) related to chemolithoautotrophs was consistent with the oxidation of reduced iron, sulfur, and nitrogen compounds having important roles as pathways for primary production in this permanently dark ecosystem. Further, the prevalence of Methylobacter in surficial lake sediments combined with the detection of methanogenic taxa in the deepest sediment horizons analyzed (34-36 cm) supported the hypothesis that methane cycling occurs beneath the West Antarctic Ice Sheet. Large ratios of rRNA to rDNA were observed for several operational taxonomic units abundant in the water column and sediments (e.g., Albidiferax, Methylobacter, Candidatus Nitrotoga, Sideroxydans, and Smithella), suggesting a potentially active role for these taxa in the SLW ecosystem. Our findings are consistent with chemosynthetic microorganisms serving as the ecological foundation in this dark subsurface environment, providing new organic matter that sustains a microbial ecosystem beneath the West Antarctic Ice Sheet. PMID- 27713728 TI - Cell-Free Spent Media Obtained from Bifidobacterium bifidum and Bifidobacterium crudilactis Grown in Media Supplemented with 3'-Sialyllactose Modulate Virulence Gene Expression in Escherichia coli O157:H7 and Salmonella Typhimurium. AB - Complex oligosaccharides from human milk (HMO) possess an antimicrobial activity and can promote the growth of bifidobacteria such as Bifidobacterium bifidum and Bifidobacterium longum subsp. infantis. In addition, fermentation of carbohydrates by bifidobacteria can result in the production of metabolites presenting an antivirulence effect on several pathogenic bacteria. Whey is rich in complex bovine milk oligosaccharides (BMO) structurally similar to HMO and B. crudilactis, a species of bovine origin, is able to metabolize some of those complex carbohydrates. This study focused on the ability of B. bifidum and B. crudilactis to grow in a culture medium supplemented in 3'-sialyllactose (3'SL) as the main source of carbon, a major BMO encountered in cow milk. Next, the effects of cell-free spent media (CFSM) were tested against virulence expression of Escherichia coli O157:H7 and Salmonella enterica serovar Typhimurium. Both strains were able to grow in presence of 3'SL, but B. crudilactis showed the best growth (7.92 +/- 0.3 log cfu/ml) compared to B. bifidum (6.84 +/- 0.9 log cfu/ml). Then, CFSM were tested for their effects on virulence gene expression by ler and hilA promoter activity of luminescent mutants of E. coli and S. Typhimurium, respectively, and on wild type strains of E. coli O157:H7 and S. Typhimurium using RT-qPCR. All CFSM resulted in significant under expression of the ler and hilA genes for the luminescent mutants and ler (ratios of -15.4 and 8.1 respectively) and qseA (ratios of -2.1 and -3.1) for the wild type strain of E. coli O157:H7. The 3'SL, a major BMO, combined with some bifidobacteria strains of bovine or human origin could therefore be an interesting synbiotic to maintain or restore the intestinal health of young children. These effects observed in vitro will be further investigated regarding the overall phenotype of pathogenic agents and the exact nature of the active molecules. PMID- 27713729 TI - Pseudomonas fluorescens F113 Can Produce a Second Flagellar Apparatus, Which Is Important for Plant Root Colonization. AB - The genomic sequence of Pseudomonas fluorescens F113 has shown the presence of a 41 kb cluster of genes that encode the production of a second flagellar apparatus. Among 2,535 pseudomonads strains with sequenced genomes, these genes are only present in the genomes of F113 and other six strains, all but one belonging to the P. fluorescens cluster of species, in the form of a genetic island. The genes are homologous to the flagellar genes of the soil bacterium Azotobacter vinelandii. Regulation of these genes is mediated by the flhDC master operon, instead of the typical regulation in pseudomonads, which is through fleQ. Under laboratory conditions, F113 does not produce this flagellum and the flhDC operon is not expressed. However, ectopic expression of the flhDC operon is enough for its production, resulting in a hypermotile strain. This flagellum is also produced under laboratory conditions by the kinB and algU mutants. Genetic analysis has shown that kinB strongly represses the expression of the flhDC operon. This operon is activated by the Vfr protein probably in a c-AMP dependent way. The strains producing this second flagellum are all hypermotile and present a tuft of polar flagella instead of the single polar flagellum produced by the wild-type strain. Phenotypic variants isolated from the rhizosphere produce this flagellum and mutation of the genes encoding it, results in a defect in competitive colonization, showing its importance for root colonization. PMID- 27713730 TI - High Iron-Sequestrating Bifidobacteria Inhibit Enteropathogen Growth and Adhesion to Intestinal Epithelial Cells In vitro. AB - The gut microbiota plays an important role in host health, in particular by its barrier effect and competition with exogenous pathogenic bacteria. In the present study, the competition of Bifidobacterium pseudolongum PV8-2 (Bp PV8-2) and Bifidobacterium kashiwanohense PV20-2 (Bk PV20-2), isolated from anemic infant gut microbiota and selected for their high iron sequestration properties, was investigated against Salmonella Typhimurium (S. Typhi) and Escherichia coli O157:H45 (EHEC) by using co-culture tests and assays with intestinal cell lines. Single and co-cultures were carried out anaerobically in chemically semi-defined low iron (1.5 MUM Fe) medium (CSDLIM) without and with added ferrous iron (30 MUM Fe). Surface properties of the tested strains were measured by bacterial adhesion to solvent xylene, chloroform, ethyl acetate, and to extracellular matrix molecules, mucus II, collagen I, fibrinogen, fibronectin. HT29-MTX mucus secreting intestinal cell cultures were used to study bifidobacteria competition, inhibition and displacement of the enteropathogens. During co-cultures in CSDLIM we observed strain-dependent inhibition of bifidobacterial strains on enteropathogens, independent of pH, organic acid production and supplemented iron. Bp PV8-2 significantly (P < 0.05) inhibited S. Typhi N15 and EHEC after 24 h compared to single culture growth. In contrast Bk PV20-2 showed less inhibition on S. Typhi N15 than Bp PV8-2, and no inhibition on EHEC. Affinity for intestinal cell surface glycoproteins was strain-specific, with high affinity of Bp PV8-2 for mucin and Bk PV20-2 for fibronectin. Bk PV20-2 showed high adhesion potential (15.6 +/- 6.0%) to HT29-MTX cell layer compared to Bp PV8-2 (1.4 +/- 0.4%). In competition, inhibition and displacement tests, Bp PV8-2 significantly (P < 0.05) reduced S. Typhi N15 and EHEC adhesion, while Bk PV20-2 was only active on S. Typhi N15 adhesion. To conclude, bifidobacterial strains selected for their high iron binding properties inhibited S. Typhi N15 and EHEC in co-culture experiments and efficiently competed with the enteropathogens on mucus-producing HT29-MTX cell lines. Further studies in complex gut ecosystems should explore host protection effects of Bp PV8-2 and Bk PV20-2 mediated by nutritional immunity mechanism associated with iron-binding. PMID- 27713732 TI - Armadillidin H, a Glycine-Rich Peptide from the Terrestrial Crustacean Armadillidium vulgare, Displays an Unexpected Wide Antimicrobial Spectrum with Membranolytic Activity. AB - Antimicrobial peptides (AMPs) are key components of innate immunity and are widespread in nature, from bacteria to vertebrate animals. In crustaceans, there are currently 15 distinct AMP families published so far in the literature, mainly isolated from members of the Decapoda order. Up to now, armadillidin is the sole non-decapod AMP isolated from the haemocytes of Armadillidium vulgare, a crustacean isopod. Its first description demonstrated that armadillidin is a linear glycine-rich (47%) cationic peptide with an antimicrobial activity directed toward Bacillus megaterium. In the present work, we report identification of armadillidin Q, a variant of armadillidin H (earlier known as armadillidin), from crude haemocyte extracts of A. vulgare using LC-MS approach. We demonstrated that both armadillidins displayed broad spectrum antimicrobial activity against several Gram-positive and Gram-negative bacteria, fungi, but were totally inactive against yeasts. Membrane permeabilization assays, only performed with armadillidin H, showed that the peptide is membrane active against bacterial and fungal strains leading to deep changes in cell morphology. This damaging activity visualized by electronic microscopy correlates with a rapid decrease of cell viability leading to highly blebbed cells. In contrast, armadillidin H does not reveal cytotoxicity toward human erythrocytes. Furthermore, no secondary structure could be defined in this study [by circular dichroism (CD) and nuclear magnetic resonance (NMR)] even in a membrane mimicking environment. Therefore, armadillidins represent interesting candidates to gain insight into the biology of glycine-rich AMPs.

AB - Bacillus methanolicus is a thermophilic methylotroph able to overproduce amino acids from methanol, a substrate not used for human or animal nutrition. Based on our previous RNA-seq analysis a mannitol inducible promoter and a putative mannitol activator gene mtlR were identified. The mannitol inducible promoter was applied for controlled gene expression using fluorescent reporter proteins and a flow cytometry analysis, and improved by changing the -35 promoter region and by co-expression of the mtlR regulator gene. For independent complementary gene expression control, the heterologous xylose-inducible system from B. megaterium was employed and a two-plasmid gene expression system was developed. Four different replicons for expression vectors were compared with respect to their copy number and stability. As an application example, methanol-based production of cadaverine was shown to be improved from 11.3 to 17.5 g/L when a heterologous lysine decarboxylase gene cadA was expressed from a theta-replicating rather than a rolling-circle replicating vector. The current work on inducible promoter systems and compatible theta- or rolling circle-replicating vectors is an important extension of the poorly developed B. methanolicus genetic toolbox, valuable for genetic engineering and further exploration of this bacterium. PMID- 27713733 TI - Bacteriome-Localized Intracellular Symbionts in Pollen-Feeding Beetles of the Genus Dasytes (Coleoptera, Dasytidae). AB - Several insect taxa are associated with intracellular symbionts that provision limiting nutrients to their hosts. Such tightly integrated symbioses are especially common in insects feeding on nutritionally challenging diets like phloem sap or vertebrate blood, but also occur in seed-eating and omnivorous taxa. Here, we characterize an intracellular symbiosis in pollen-feeding beetles of the genus Dasytes (Coleoptera, Dasytidae). High-throughput tag-encoded 16S amplicon pyrosequencing of adult D. plumbeus and D. virens revealed a single gamma-proteobacterial symbiont ('Candidatus Dasytiphilus stammeri') that amounts to 52.4-98.7% of the adult beetles' entire microbial community. Almost complete 16S rRNA sequences phylogenetically placed the symbiont into a clade comprising Buchnera and other insect endosymbionts, but sequence similarities to these closest relatives were surprisingly low (83.4-87.4%). Using histological examination, three-dimensional reconstructions, and fluorescence in situ hybridization, we localized the symbionts in three mulberry-shaped bacteriomes that are associated with the mid- to hind-gut transition in adult male and female beetles. Given the specialized pollen-feeding habits of the adults that contrasts with the larvae's carnivorous lifestyle, the symbionts may provision limiting essential amino acids or vitamins as in other intracellular symbioses, or they might produce digestive enzymes that break up the fastidious pollen walls and thereby contribute to the host's nutrition. In either case, the presence of gamma proteobacterial symbionts in pollen-feeding beetles indicates that intracellular mutualists are more widely distributed across insects with diverse feeding habits than previously recognized. PMID- 27713734 TI - The Highly Conserved Escherichia coli Transcription Factor YhaJ Regulates Aromatic Compound Degradation. AB - The aromatic compound 2,4-dinitrotoluene (DNT), a common impurity in 2,4,6 trinitrotoluene (TNT) production, has been suggested as a tracer for the presence of TNT-based landmines due to its stability and high volatility. We have previously described an Escherichia coli bioreporter capable of detecting the presence of DNT vapors, harboring a fusion of the yqjF gene promoter to a reporter element. However, the DNT metabolite which is the direct inducer of yqjF, has not yet been identified, nor has the regulatory mechanism of the induction been clarified. We demonstrate here that the YhaJ protein, a member of the LysR type family, acts as a transcriptional regulator of yqjF activation, as well as of a panel of additional E. coli genes. This group of genes share a common sequence motif in their promoters, which is suggested here as a putative YhaJ-box. In addition, we have linked YhaJ to the regulation of quinol-like compound degradation in the cell, and identified yhaK as playing a role in the degradation of DNT. PMID- 27713735 TI - Modulation of the Bifidobacterial Communities of the Dog Microbiota by Zeolite. AB - During last decades canine health and well being is becoming an important issue for human owners. In dogs, several factors including diet, pathogenic bacterial and stress conditions can affect the composition of the gut microbiota. In this study, we evaluated the effect of dietary chabazitic zeolitite (CZ) supplementation on the contribution of bifidobacteria to the fecal microbiota in training hunting dogs. Fecal microbiota cataloging based on 16S rRNA microbial profiling analyses highlighted an increase of Lactobacillus and Bifidobacterium in animals treated with CZ, with a simultaneous decrease of pathogens associated with dog gastrointestinal infections, such as Klebsiella and Enterobacter. A detailed profiling of the bifidobacterial population of dogs receiving CZ based on the ITS-based sequencing approach, revealed an enhancement bifidobacterial of species typical of animals such as Bifidobacterium animalis and B. pseudolongum. Moreover, these analyses identified the occurrence of putative new bifidobacterial taxa in both treated and untreated samples. PMID- 27713736 TI - Identification and Characterization of an Aeromonas hydrophila Oligopeptidase Gene pepF Negatively Related to Biofilm Formation. AB - Bacterial biofilms are involved in adaptation to complex environments and are responsible for persistent bacterial infections. Biofilm formation is a highly complex process during which multifarious genes work together regularly. In this study, we screened the EZ-Tn5 transposon mutant library to identify genes involved in biofilm formation of Aeromonas hydrophila. A total of 24 biofilm associated genes were identified, the majority of which encoded proteins related to cell structure, transcription and translation, gene regulation, growth and metabolism. The mutant strain TM90, in which a gene encoding oligopeptidase F (pepF) was disturbed, showed significant upregulation of biofilm formation compared to the parental strain. The TM90 colony phenotype was smaller, more transparent, and splendent. The adhesive ability of TM90 to HEp-2 cells was significantly increased compared with the parental strain. Fifty percent lethal dose (LD50) determinations in zebrafish demonstrated that the enhanced-biofilm mutant TM90 was highly attenuated relative to the wild-type strain. In conclusion, the pepF gene is demonstrated for the first time to be a negative factor for biofilm formation and is involved in A. hydrophila pathogenicity. PMID- 27713737 TI - Development of a Method to Determine the Effectiveness of Cleaning Agents in Removal of Biofilm Derived Spores in Milking System. AB - Microbial damages caused by biofilm forming bacteria in the dairy industry are a fundamental threat to safety and quality of dairy products. In order to ensure the optimal level of equipment hygiene in the dairy industry, it is necessary to determine the biofilm removal efficiency of cleaning agents used for cleaning-in place (CIP) procedures. However, currently there is no standard method available for evaluating and comparing cleaning agents for use in CIP procedures in the dairy industry under realistic conditions. The present study aims to establish a CIP model system to evaluate the effectiveness of cleaning agents in removal of biofilm derived spores from the surfaces of stainless steel which is the predominant substrate in milking equipment on dairy farms. The system is based on Bacillus subtilis spores surrounded with exopolymeric substances produced by bacteria during biofilm formation. The spores applied on sampling plates were mounted on T-junctions protruding 1.5-11-times the milk pipe diameter from the main loop to resemble different levels of cleaning difficulty. The cleaning tests were conducted using commercial alkaline detergents and caustic soda at conditions which are relevant to actual farm environment. The spores removal effect was evaluated by comparing the number of viable spores (attached to sampling plates) before and after cleaning. Evaluation of the cleaning and disinfecting effect of cleaning agents toward biofilm derived spores was further performed, which indicates whether spores elimination effect of an agent is due to killing the spores or removing them from the surfaces of dairy equipment. Moreover, it was established that the presence of extracellular matrix is an important factor responsible for high level of cleaning difficulty characteristic for surface attached spores. In overall, the results of this study suggest that the developed model system simulates actual farm conditions for quantitative evaluation of the effectiveness of cleaning and disinfecting agents and their cleaning and disinfecting effect on removal of biofilm derived spores. PMID- 27713738 TI - Quantification of Virus Particles Using Nanopore-Based Resistive-Pulse Sensing Techniques. AB - Viruses have drawn much attention in recent years due to increased recognition of their important roles in virology, immunology, clinical diagnosis, and therapy. Because the biological and physical properties of viruses significantly impact their applications, quantitative detection of individual virus particles has become a critical issue. However, due to various inherent limitations of conventional enumeration techniques such as infectious titer assays, immunological assays, and electron microscopic observation, this issue remains challenging. Thanks to significant advances in nanotechnology, nanostructure based electrical sensors have emerged as promising platforms for real-time, sensitive detection of numerous bioanalytes. In this paper, we review recent progress in nanopore-based electrical sensing, with particular emphasis on the application of this technique to the quantification of virus particles. Our aim is to provide insights into this novel nanosensor technology, and highlight its ability to enhance current understanding of a variety of viruses. PMID- 27713739 TI - Quantification of Viral and Prokaryotic Production Rates in Benthic Ecosystems: A Methods Comparison. AB - Viruses profoundly influence benthic marine ecosystems by infecting and subsequently killing their prokaryotic hosts, thereby impacting the cycling of carbon and nutrients. Previously conducted studies, based on different methodologies, have provided widely differing estimates of the relevance of viruses on benthic prokaryotes. There has been no attempt so far to compare these independent approaches, including contextual comparisons among different approaches for sample manipulation (i.e., dilution or not of the sediments during incubations), between methods based on epifluorescence microscopy (EFM) or radiotracers, and between the use of different radiotracers. Therefore, it has been difficult to identify the most suitable methodologies and protocols to be used as standard approaches for the quantification of viral infections of prokaryotes. Here, we compared for the first time different methods for determining viral and prokaryotic production rates in marine sediments collected at two benthic sites, differing in depth and environmental conditions. We used a highly replicated experimental design, testing the potential biases associated to the incubation of sediments as diluted or undiluted. In parallel, we also compared EFM counts with the 3H-thymidine incubations for the determination of viral production rates, and the use of 3H-thymidine versus 3H-leucine radiotracers for the determination of prokaryotic production. We show here that, independent from sediment dilution, EFM-based values of viral production ranged from 1.4 to 4.6 * 107 viruses g-1 h-1, and were similar but overall less variable compared to those obtained by the 3H-thymidine method (0.3 to 9.0 * 107 viruses g 1h-1). In addition, the prokaryotic production rates were not affected by sediment dilution, and the use of different radiotracers provided very consistent estimates (10.3-35.1 and 9.3-34.6 ngC g-1h-1 using the 3H-thymidine or 3H-leucine method, respectively). These results indicated that viral lysis was responsible for the abatement of 55-81% of the prokaryotic heterotrophic production, corroborating previous findings of the major role of viruses in benthic deep-sea ecosystems. Moreover, our methodological comparison for the analysis of viral production in marine sediments suggests that microscopy-based approaches are simpler and more cost-effective than those based on radiotracers. These approaches also reduce time to results and overcome issues related to generation of radioactive waste. PMID- 27713741 TI - Engineering of TM1459 from Thermotoga maritima for Increased Oxidative Alkene Cleavage Activity. AB - Oxidative cleavage of alkenes is a widely employed process allowing oxyfunctionalization to corresponding carbonyl compounds. Recently, a novel biocatalytic oxidative alkene cleavage activity on styrene derivatives was identified in TM1459 from Thermotoga maritima. In this work we engineered the enzyme by site-saturation mutagenesis of active site amino acids to increase its activity and to broaden its substrate scope. A high-throughput assay for the detection of the ketone products was successfully developed. Several variants with up to twofold improved conversion level of styrene derivatives were successfully identified. Especially, changes in or removal of the C-terminus of TM1459 increased the activity most significantly. These best variants also displayed a slightly enlarged substrate scope. PMID- 27713743 TI - Mastitis Pathogens with High Virulence in a Mouse Model Produce a Distinct Cytokine Profile In Vivo. AB - Mastitis is a serious medical condition of dairy cattle. Here, we evaluated whether the degree of virulence of mastitis pathogens in a mouse model can be linked to the inflammatory response that they provoke. Clinical isolates of Staphylococcus aureus (S. aureus) (strain 556 and 392) and Escherichia coli (E. coli) (676 and 127), and laboratory control strains [8325-4 (S. aureus) and MG1655 (E. coli)], were injected i.p. into mice, followed by the assessment of clinical scores and inflammatory parameters. As judged by clinical scoring, E. coli 127 exhibited the largest degree of virulence among the strains. All bacterial strains induced neutrophil recruitment. However, whereas E. coli 127 induced high peritoneal levels of CXCL1, G-CSF, and CCL2, strikingly lower levels of these were induced by the less virulent bacterial strains. High concentrations of these compounds were also seen in blood samples taken from animals infected with E. coli 127, suggesting systemic inflammation. Moreover, the levels of CXCL1 and G-CSF, both in the peritoneal fluid and in plasma, correlated with clinical score. Together, these findings suggest that highly virulent clinical mastitis isolates produce a distinct cytokine profile that shows a close correlation with the severity of the bacterial infection. PMID- 27713742 TI - PtrA Is Functionally Intertwined with GacS in Regulating the Biocontrol Activity of Pseudomonas chlororaphis PA23. AB - In vitro inhibition of the fungal pathogen Sclerotinia sclerotiorum by Pseudomonas chlororaphis PA23 is reliant upon a LysR-type transcriptional regulator (LTTR) called PtrA. In the current study, we show that Sclerotinia stem rot and leaf infection are significantly increased in canola plants inoculated with the ptrA-mutant compared to the wild type, establishing PtrA as an essential regulator of PA23 biocontrol. LTTRs typically regulate targets that are upstream of and divergently transcribed from the LTTR locus. We identified a short chain dehydrogenase (scd) gene immediately upstream of ptrA. Characterization of a scd mutant revealed that it is phenotypically identical to the wild type. Moreover, scd transcript abundance was unchanged in the ptrA mutant. These findings indicate that PtrA regulation does not involve scd, rather this LTTR controls genes located elsewhere on the chromosome. Employing a combination of complementation and transcriptional analysis we investigated whether connections exist between PtrA and other regulators of biocontrol. Besides ptrA, gacS was the only gene able to partially rescue the wild-type phenotype, establishing a connection between PtrA and the sensor kinase GacS. Transcriptomic analysis revealed decreased expression of biosynthetic (phzA, prnA) and regulatory genes (phzI, phzR, rpoS, gacA, rsmX, rsmZ, retS) in the ptrA mutant; conversely, rsmE, and rsmY were markedly upregulated. The transcript abundance of ptrA was nine fold higher in the mutant background indicating that this LTTR negatively autoregulates itself. In summary, PtrA is an essential regulator of genes required for PA23 biocontrol that is functionally intertwined with GacS. PMID- 27713740 TI - Stuck in the Middle: Fibronectin-Binding Proteins in Gram-Positive Bacteria. AB - Fibronectin is a multidomain glycoprotein found ubiquitously in human body fluids and extracellular matrices of a variety of cell types from all human tissues and organs, including intestinal epithelial cells. Fibronectin plays a major role in the regulation of cell migration, tissue repair, and cell adhesion. Importantly, fibronectin also serves as a common target for bacterial adhesins in the gastrointestinal tract. Fibronectin-binding proteins (FnBPs) have been identified and characterized in a wide variety of host-associated bacteria. Single bacterial species can contain multiple, diverse FnBPs. In pathogens, some FnBPs contribute to virulence via host cell attachment, invasion, and interference with signaling pathways. Although FnBPs in commensal and probiotic strains are not sufficient to confer virulence, they are essential for attachment to their ecological niches. Here we describe the interaction between human fibronectin and bacterial adhesins by highlighting the FnBPs of Gram-positive pathogens and commensals. We provide an overview of the occurrence and diversity of FnBPs with a focus on the model pathogenic organisms in which FnBPs are most characterized. Continued investigation of FnBPs is needed to fully understand their divergence and specificity in both pathogens and commensals. PMID- 27713744 TI - Peripheral and Central Neuroinflammatory Changes and Pain Behaviors in an Animal Model of Multiple Sclerosis. AB - Pain is a widespread and debilitating symptom of multiple sclerosis (MS), a chronic inflammatory demyelinating disease of the central nervous system. Although central neuroinflammation and demyelination have been implicated in MS related pain, the contribution of peripheral and central mechanisms during different phases of the disease remains unclear. In this study, we used the animal model experimental autoimmune encephalomyelitis (EAE) to examine both stimulus-evoked and spontaneous pain behaviors, and neuroinflammatory changes, over the course of chronic disease. We found that mechanical allodynia of the hind paw preceded the onset of clinical EAE but was unmeasurable at clinical peak. This mechanical hypersensitivity coincided with increased microglial activation confined to the dorsal horn of the spinal cord. The development of facial mechanical allodynia also emerged in preclinical EAE, persisted at the clinical peak, and corresponded with pathology of the peripheral trigeminal afferent pathway. This included T cell infiltration, which arose prior to overt central lesion formation and specific damage to myelinated neurons during the clinical peak. Measurement of spontaneous pain using the mouse grimace scale, a facial expression-based coding system, showed increased facial grimacing in mice with EAE during clinical disease. This was associated with multiple peripheral and central neuroinflammatory changes including a decrease in myelinating oligodendrocytes, increased T cell infiltration, and macrophage/microglia and astrocyte activation. Overall, these findings suggest that different pathological mechanisms may underlie stimulus-evoked and spontaneous pain in EAE, and that these behaviors predominate in unique stages of the disease. PMID- 27713746 TI - Estrous Cycle and Gestational Age-Dependent Expression of Members of the Interleukin-36 Subfamily in a Semi-Allogeneic Model of Infected and Non-Infected Murine Pregnancy. AB - The IL-36 subfamily is a recently described group of cytokines with pro inflammatory behavior, comprising three agonists (alpha, beta, and gamma), its receptor (R), and one antagonist (Ra). The expression and function of IL-36 subfamily members in the estrous cycle in healthy and infected pregnancy has not been described. We evaluated mRNA and protein expression of IL-36 family members during the estrous cycle, implantation, fetal development, and post-labor periods in a model of allogenic pregnancy in mice. We also explored the ability of Listeria monocytogenes to modulate the expression of IL-36 subfamily members during pregnancy. Expression of IL-36 subfamily members showed different expression during the estrous cycle and pregnancy but was induced at estrous, 16.5 days post coitum (dpc), 18.5 dpc, and labor. IL-36 subfamily members showed a characteristic distribution in the glandular epithelium, perimetrium, myometrium, and stratum vasculare. Infection with L. monocytogenes during pregnancy induced strong production of IL-36 subfamily members, an observation that correlated with an increasing prevalence of fetal loss. In conclusion, IL-36 agonists showed specific patterns of mRNA and protein expression that might suggest functional specialization or specific target cells. Infection with L. monocytogenes during pregnancy induced strong production of IL-36 subfamily members. PMID- 27713745 TI - Phosphocholine-Specific Antibodies Improve T-Dependent Antibody Responses against OVA Encapsulated into Phosphatidylcholine-Containing Liposomes. AB - Liposomes containing phosphatidylcholine have been widely used as adjuvants. Recently, we demonstrated that B-1 cells produce dipalmitoyl-phosphatidylcholine (DPPC)-specific IgM upon immunization of BALB/c mice with DPPC-liposomes encapsulating ovalbumin (OVA). Although this preparation enhanced the OVA specific humoral response, the contribution of anti-DPPC antibodies to this effect was unclear. Here, we demonstrate that these antibodies are secreted by B 1 cells independently of the presence of OVA in the formulation. We also confirm that these antibodies are specific for phosphocholine. The anti-OVA humoral response was partially restored in B-1 cells-deficient BALB/xid mice by immunization with the liposomes opsonized with the serum total immunoglobulin (Ig) fraction containing anti-phosphocholine antibodies, generated in wild-type animals. This result could be related to the increased phagocytosis by peritoneal macrophages of the particles opsonized with the serum total Ig or IgM fractions, both containing anti-phosphocholine antibodies. In conclusion, in the present work, it has been demonstrated that phosphocholine-specific antibodies improve T dependent antibody responses against OVA carried by DPPC-liposomes. PMID- 27713747 TI - Crosstalk between Wnt/beta-Catenin and NF-kappaB Signaling Pathway during Inflammation. AB - Besides its important role in embryonic development and homeostatic self-renewal in adult tissues, Wnt/beta-catenin signaling exerts both anti-inflammatory and proinflammatory functions. This is, at least partially, due to either repressing or enhancing the NF-kappaB pathway. Similarly, the NF-kappaB pathway either positively or negatively regulates Wnt/beta-catenin signaling. Different components of the two pathways are involved in this crosstalk, forming a complex regulatory network. This review summarizes our current understanding of the molecular mechanisms underlying the cross-regulation between the two pathways and discusses their involvement in inflammation and inflammation-associated diseases such as cancer. PMID- 27713748 TI - Indomethacin Treatment of Mice with Premalignant Oral Lesions Sustains Cytokine Production and Slows Progression to Cancer. AB - Current treatment options for head and neck squamous cell carcinoma (HNSCC) patients are often ineffective due to tumor-localized and systemic immunosuppression. Using the 4-NQO mouse model of oral carcinogenesis, this study showed that premalignant oral lesion cells produce higher levels of the immune modulator, PGE2, compared to HNSCC cells. Inhibiting prostaglandin production of premalignant lesion cells with the pan-cyclooxygenase inhibitor indomethacin stimulated their induction of spleen cell cytokine production. In contrast, inhibiting HNSCC prostaglandin production did not stimulate their induction of spleen cell cytokine production. Treatment of mice bearing premalignant oral lesions with indomethacin slowed progression of premalignant oral lesions to HNSCC. Flow cytometric analysis of T cells in the regional lymph nodes of lesion bearing mice receiving indomethacin treatment showed an increase in lymph node cellularity and in the absolute number of CD8+ T cells expressing IFN-gamma compared to levels in lesion-bearing mice receiving diluent control treatment. The cytokine-stimulatory effect of indomethacin treatment was not localized to regional lymph nodes but was also seen in the spleen of mice with premalignant oral lesions. Together, these data suggest that inhibiting prostaglandin production at the premalignant lesion stage boosts immune capability and improves clinical outcomes. PMID- 27713749 TI - Genomic Dissection and Expression Profiling Revealed Functional Divergence in Triticum aestivum Leucine Rich Repeat Receptor Like Kinases (TaLRRKs). AB - The leucine rich repeat receptor like kinases (LRRK) constitute the largest subfamily of receptor like kinases (RLK), which play critical roles in plant development and stress responses. Herein, we identified 531 TaLRRK genes in Triticum aestivum (bread wheat), which were distributed throughout the A, B, and D sub-genomes and chromosomes. These were clustered into 233 homologous groups, which were mostly located on either homeologous chromosomes from various sub genomes or in proximity on the same chromosome. A total of 255 paralogous genes were predicted which depicted the role of duplication events in expansion of this gene family. Majority of TaLRRKs consisted of trans-membrane region and localized on plasma-membrane. The TaLRRKs were further categorized into eight phylogenetic groups with numerous subgroups on the basis of sequence homology. The gene and protein structure in terms of exon/intron ratio, domains, and motifs organization were found to be variably conserved across the different phylogenetic groups/subgroups, which indicated a potential divergence and neofunctionalization during evolution. High-throughput transcriptome data and quantitative real time PCR analyses in various developmental stages, and biotic and abiotic (heat, drought, and salt) stresses provided insight into modus operandi of TaLRRKs during these conditions. Distinct expression of majority of stress responsive TaLRRKs homologous genes suggested their specified role in a particular condition. These results provided a comprehensive analysis of various characteristic features including functional divergence, which may provide the way for future functional characterization of this important gene family in bread wheat. PMID- 27713751 TI - Comparative Evaluation of Biochemical Changes in Tomato (Lycopersicon esculentum Mill.) Infected by Alternaria alternata and Its Toxic Metabolites (TeA, AOH, and AME). AB - In the present study, we have evaluated the comparative biochemical defense response generated against Alternaria alternata and its purified toxins viz. alternariol (AOH), alternariol monomethyl ether (AME), and tenuazonic acid (TeA). The necrotic lesions developed due to treatment with toxins were almost similar as those produced by the pathogen, indicating the crucial role of these toxins in plant pathogenesis. An oxidative burst reaction characterized by the rapid and transient production of a large amount of reactive oxygen species (ROS) occurs following the pathogen infection/toxin exposure. The maximum concentration of hydrogen peroxide (H2O2) produced was reported in the pathogen infected samples (22.2-fold) at 24 h post inoculation followed by TeA (18.2-fold), AOH (15.9 fold), and AME (14.1-fold) in treated tissues. 3,3'- Diaminobenzidine staining predicted the possible sites of H2O2 accumulation while the extent of cell death was measured by Evans blue dye. The extent of lipid peroxidation and malondialdehyde (MDA) content was higher (15.8-fold) at 48 h in the sample of inoculated leaves of the pathogen when compared to control. The cellular damages were observed as increased MDA content and reduced chlorophyll. The activities of antioxidative defense enzymes increased in both the pathogen infected as well as toxin treated samples. Superoxide dismutase (SOD) activity was 5.9-fold higher at 24 h post inoculation in leaves followed by TeA (5.0-fold), AOH (4.1-fold) and AME (2.3-fold) treated leaves than control. Catalase (CAT) activity was found to be increased upto 48 h post inoculation and maximum in the pathogen challenged samples followed by other toxins. The native PAGE results showed the variations in the intensities of isozyme (SOD and CAT) bands in the pathogen infected and toxin treated samples. Ascorbate peroxidase (APx) and glutathione reductase (GR) activities followed the similar trend to scavenge the excess H2O2. The reduction in CAT activities after 48 h post inoculation demonstrate that the biochemical defense programming shown by the host against the pathogen is not well efficient resulting in the compatible host-pathogen interaction. The elicitor (toxins) induced biochemical changes depends on the potential toxic effects (extent of ROS accumulation, amount of H2O2 produced). Thus, a fine tuning occurs for the defense related antioxidative enzymes against detoxification of key ROS molecules and effectively regulated in tomato plant against the pathogen infected/toxin treated oxidative stress. The study well demonstrates the acute pathological effects of A. alternata in tomato over its phytotoxic metabolites. PMID- 27713752 TI - Using Deep Learning for Image-Based Plant Disease Detection. AB - Crop diseases are a major threat to food security, but their rapid identification remains difficult in many parts of the world due to the lack of the necessary infrastructure. The combination of increasing global smartphone penetration and recent advances in computer vision made possible by deep learning has paved the way for smartphone-assisted disease diagnosis. Using a public dataset of 54,306 images of diseased and healthy plant leaves collected under controlled conditions, we train a deep convolutional neural network to identify 14 crop species and 26 diseases (or absence thereof). The trained model achieves an accuracy of 99.35% on a held-out test set, demonstrating the feasibility of this approach. Overall, the approach of training deep learning models on increasingly large and publicly available image datasets presents a clear path toward smartphone-assisted crop disease diagnosis on a massive global scale. PMID- 27713750 TI - Non-invasive Presymptomatic Detection of Cercospora beticola Infection and Identification of Early Metabolic Responses in Sugar Beet. AB - Cercospora beticola is an economically significant fungal pathogen of sugar beet, and is the causative pathogen of Cercospora leaf spot. Selected host genotypes with contrasting degree of susceptibility to the disease have been exploited to characterize the patterns of metabolite responses to fungal infection, and to devise a pre-symptomatic, non-invasive method of detecting the presence of the pathogen. Sugar beet genotypes were analyzed for metabolite profiles and hyperspectral signatures. Correlation of data matrices from both approaches facilitated identification of candidates for metabolic markers. Hyperspectral imaging was highly predictive with a classification accuracy of 98.5-99.9% in detecting C. beticola. Metabolite analysis revealed metabolites altered by the host as part of a successful defense response: these were L-DOPA, 12 hydroxyjasmonic acid 12-O-beta-D-glucoside, pantothenic acid, and 5-O feruloylquinic acid. The accumulation of glucosylvitexin in the resistant cultivar suggests it acts as a constitutively produced protectant. The study establishes a proof-of-concept for an unbiased, presymptomatic and non-invasive detection system for the presence of C. beticola. The test needs to be validated with a larger set of genotypes, to be scalable to the level of a crop improvement program, aiming to speed up the selection for resistant cultivars of sugar beet. Untargeted metabolic profiling is a valuable tool to identify metabolites which correlate with hyperspectral data. PMID- 27713753 TI - The Woody-Preferential Gene EgMYB88 Regulates the Biosynthesis of Phenylpropanoid Derived Compounds in Wood. AB - Comparative phylogenetic analyses of the R2R3-MYB transcription factor family revealed that five subgroups were preferentially found in woody species and were totally absent from Brassicaceae and monocots (Soler et al., 2015). Here, we analyzed one of these subgroups (WPS-I) for which no gene had been yet characterized. Most Eucalyptus members of WPS-I are preferentially expressed in the vascular cambium, the secondary meristem responsible for tree radial growth. We focused on EgMYB88, which is the most specifically and highly expressed in vascular tissues, and showed that it behaves as a transcriptional activator in yeast. Then, we functionally characterized EgMYB88 in both transgenic Arabidopsis and poplar plants overexpressing either the native or the dominant repression form (fused to the Ethylene-responsive element binding factor-associated Amphiphilic Repression motif, EAR). The transgenic Arabidopsis lines had no phenotype whereas the poplar lines overexpressing EgMYB88 exhibited a substantial increase in the levels of the flavonoid catechin and of some salicinoid phenolic glycosides (salicortin, salireposide, and tremulacin), in agreement with the increase of the transcript levels of landmark biosynthetic genes. A change in the lignin structure (increase in the syringyl vs. guaiacyl, S/G ratio) was also observed. Poplar lines overexpressing the EgMYB88 dominant repression form did not show a strict opposite phenotype. The level of catechin was reduced, but the levels of the salicinoid phenolic glycosides and the S/G ratio remained unchanged. In addition, they showed a reduction in soluble oligolignols containing sinapyl p-hydroxybenzoate accompanied by a mild reduction of the insoluble lignin content. Altogether, these results suggest that EgMYB88, and more largely members of the WPS-I group, could control in cambium and in the first layers of differentiating xylem the biosynthesis of some phenylpropanoid derived secondary metabolites including lignin. PMID- 27713754 TI - Transcriptome Analysis of Sucrose Metabolism during Bulb Swelling and Development in Onion (Allium cepa L.). AB - Allium cepa L. is a widely cultivated and economically significant vegetable crop worldwide, with beneficial dietary and health-related properties, but its sucrose metabolism is still poorly understood. To analyze sucrose metabolism during bulb swelling, and the development of sweet taste in onion, a global transcriptome profile of onion bulbs was undertaken at three different developmental stages, using RNA-seq. A total of 79,376 unigenes, with a mean length of 678 bp, was obtained. In total, 7% of annotated Clusters of Orthologous Groups (COG) were involved in carbohydrate transport and metabolism. In the Kyoto Encyclopedia of Genes and Genomes (KEGG) database, "starch and sucrose metabolism" (147, 2.40%) constituted the primary metabolism pathway in the integrated library. The expression of sucrose transporter genes was greatest during the early-swelling stage, suggesting that sucrose transporters (SUTs) participated in sucrose metabolism mainly at an early stage of bulb development. A gene-expression analysis of the key enzymes of sucrose metabolism suggested that sucrose synthase, cell wall invertase, and invertase were all likely to participate in the hydrolysis of sucrose, generating glucose, and fructose. In addition, trehalose was hydrolyzed to two molecules of glucose by trehalase. From 15 to 40 days after swelling (DAS), both the glucose and fructose contents of bulbs increased, whereas the sucrose content decreased. The growth rate between 15 and 30 DAS was slower than that between 30 and 40 DAS, suggesting that the latter was a period of rapid expansion. The dataset generated by our transcriptome profiling will provide valuable information for further research. PMID- 27713756 TI - Effects of Selected Diazotrophs on Maize Growth. AB - Laboratory, greenhouse, and field experiments were conducted at the University of KwaZulu-Natal, Pietermaritzburg, South Africa in the 2010/2011 and 2011?2012 seasons to study the effects of eight strains of diazotrophic bacteria on the growth and yield of maize. Maize seeds were treated with Bacillus megaterium (V16), Pseudomonas sp. (StB5, A3, A6, and A61), Burkholderia ambifaria (V9), Enterobacter cloacae (L1) and Pantoea ananatis (LB5), aiming to stimulate plant growth, and maintain or increase yields while reducing the need for N fertilization. All the diazotrophic bacteria increased germination of maize seed, and Pseudomonas sp. (StB5) and B. megaterium (V16) significantly increased shoot length. Pseudomonas sp. (StB5), B. megaterium (V16), E. cloacae (L1), B. ambifaria (V9), and Pseudomonas sp. (A3) very significantly increased root length and seed vigor index. Under greenhouse conditions, plants treated with diazotrophic bacteria developed more leaf chlorophyll and greater dry weight, albeit not significantly (n.s.). In a field trial in 2010/2011, application of the best five diazotrophic bacteria, with or without 33% N-fertilizer, had no significant effect on germination, grain yield, dry weight, plant height and leaf chlorophyll. In the 2011/2012 growing season, at 60 days after planting (DAP), all the diazotrophic bacteria increased plant dry weights to equal that of the fertilized control (33%N-fertilizer) (n.s.). After inoculation with the diazotrophs alone increased plant heights (n.s.), and chlorophyll contents (n.s.). With the addition of 33%N-fertilizer at planting, the diazotrophs still caused increases of chlorophyll content relative to the control with 33%N (n.s.). It may be concluded that the tested diazotrophs alone may be beneficial for use on maize growth. PMID- 27713755 TI - GUN1, a Jack-Of-All-Trades in Chloroplast Protein Homeostasis and Signaling. AB - The GENOMES UNCOUPLED 1 (GUN1) gene has been reported to encode a chloroplast localized pentatricopeptide-repeat protein, which acts to integrate multiple indicators of plastid developmental stage and altered plastid function, as part of chloroplast-to-nucleus retrograde communication. However, the molecular mechanisms underlying signal integration by GUN1 have remained elusive, up until the recent identification of a set of GUN1-interacting proteins, by co immunoprecipitation and mass-spectrometric analyses, as well as protein-protein interaction assays. Here, we review the molecular functions of the different GUN1 partners and propose a major role for GUN1 as coordinator of chloroplast translation, protein import, and protein degradation. This regulatory role is implemented through proteins that, in most cases, are part of multimeric protein complexes and whose precise functions vary depending on their association states. Within this framework, GUN1 may act as a platform to promote specific functions by bringing the interacting enzymes into close proximity with their substrates, or may inhibit processes by sequestering particular pools of specific interactors. Furthermore, the interactions of GUN1 with enzymes of the tetrapyrrole biosynthesis (TPB) pathway support the involvement of tetrapyrroles as signaling molecules in retrograde communication.

AB - Recombination occurring during meiosis is critical for creating genetic variation and plays an essential role in plant evolution. In addition to creating novel gene combinations, recombination can affect genome structure through altering GC patterns. In maize (Zea mays) and other grasses, another intriguing GC pattern exists. Maize genes show a bimodal GC content distribution that has been attributed to nucleotide bias in the third, or wobble, position of the codon. Recombination may be an underlying driving force given that recombination sites are often associated with high GC content. Here we explore the relationship between recombination and genomic GC patterns by comparing GC gene content at each of the three codon positions (GC1, GC2, and GC3, collectively termed GCx) to instances of a variable GC-rich motif that underlies double strand break (DSB) hotspots and to meiocyte-specific gene expression. Surprisingly, GCx bimodality in maize cannot be fully explained by the codon wobble hypothesis. High GCx genes show a strong overlap with the DSB hotspot motif, possibly providing a mechanism for the high evolutionary rates seen in these genes. On the other hand, genes that are turned on in meiosis (early prophase I) are biased against both high GCx genes and genes with the DSB hotspot motif, possibly allowing important meiotic genes to avoid DSBs. Our data suggests a strong link between the GC-rich motif underlying DSB hotspots and high GCx genes. PMID- 27713759 TI - Genome-Wide Differentiation of Various Melon Horticultural Groups for Use in GWAS for Fruit Firmness and Construction of a High Resolution Genetic Map. AB - Melon (Cucumis melo L.) is a phenotypically diverse eudicot diploid (2n = 2x = 24) has climacteric and non-climacteric morphotypes and show wide variation for fruit firmness, an important trait for transportation and shelf life. We generated 13,789 SNP markers using genotyping-by-sequencing (GBS) and anchored them to chromosomes to understand genome-wide fixation indices (Fst) between various melon morphotypes and genomewide linkage disequilibrium (LD) decay. The FST between accessions of cantalupensis and inodorus was 0.23. The FST between cantalupensis and various agrestis accessions was in a range of 0.19-0.53 and between inodorus and agrestis accessions was in a range of 0.21-0.59 indicating sporadic to wide ranging introgression. The EM (Expectation Maximization) algorithm was used for estimation of 1436 haplotypes. Average genome-wide LD decay for the melon genome was noted to be 9.27 Kb. In the current research, we focused on the genome-wide divergence underlying diverse melon horticultural groups. A high-resolution genetic map with 7153 loci was constructed. Genome-wide segregation distortion and recombination rate across various chromosomes were characterized. Melon has climacteric and non-climacteric morphotypes and wide variation for fruit firmness, a very important trait for transportation and shelf life. Various levels of QTLs were identified with high to moderate stringency and linked to fruit firmness using both genome-wide association study (GWAS) and biparental mapping. Gene annotation revealed some of the SNPs are located in beta D-xylosidase, glyoxysomal malate synthase, chloroplastic anthranilate phosphoribosyltransferase, and histidine kinase, the genes that were previously characterized for fruit ripening and softening in other crops. PMID- 27713760 TI - Impact of Phenylpropanoid Compounds on Heat Stress Tolerance in Carrot Cell Cultures. AB - The phenylpropanoid and flavonoid families include thousands of specialized metabolites that influence a wide range of processes in plants, including seed dispersal, auxin transport, photoprotection, mechanical support and protection against insect herbivory. Such metabolites play a key role in the protection of plants against abiotic stress, in many cases through their well-known ability to inhibit the formation of reactive oxygen species (ROS). However, the precise role of specific phenylpropanoid and flavonoid molecules is unclear. We therefore investigated the role of specific anthocyanins (ACs) and other phenylpropanoids that accumulate in carrot cells cultivated in vitro, focusing on their supposed ability to protect cells from heat stress. First we characterized the effects of heat stress to identify quantifiable morphological traits as markers of heat stress susceptibility. We then fed the cultures with precursors to induce the targeted accumulation of specific compounds, and compared the impact of heat stress in these cultures and unfed controls. Data modeling based on projection to latent structures (PLS) regression revealed that metabolites containing coumaric or caffeic acid, including ACs, correlate with less heat damage. Further experiments suggested that one of the cellular targets damaged by heat stress and protected by these metabolites is the actin microfilament cytoskeleton. PMID- 27713762 TI - Assessment of CYP1A2 enzyme activity in relation to type-2 diabetes and habitual caffeine intake. AB - BACKGROUND: Coffee consumption is a known inducer of cytochrome P450 1A2 (CYP1A2) enzyme activity. We recently observed that a group of type-2 diabetes patients consumed more caffeine (coffee) on a daily basis than non-type-2 diabetes controls. Here, we investigated whether type-2 diabetes cases may metabolize caffeine faster than non-type-2 diabetes controls. METHODS: To estimate CYP1A2 enzyme activity, an established marker of caffeine metabolism, we quantified the paraxanthine/caffeine concentration ratio in saliva in 57 type-2 diabetes and 146 non-type-2 diabetes participants in a case-control field study. All participants completed validated questionnaires regarding demographic status, health and habitual caffeine intake, and were genotyped for the functional -163C > A polymorphism of the CYP1A2 gene. RESULTS: In the diabetes group, we found a larger proportion of participants with the highly inducible CYP1A2 genotype. Furthermore, the paraxanthine/caffeine ratio, time-corrected to mitigate the impact of different saliva sampling times with respect to the last caffeine intake, was higher than in the control group. Participants who reported habitually consuming more caffeine than the population average showed higher CYP1A2 activity than participants with lower than average caffeine consumption. Multiple regression analyses revealed that higher caffeine intake was potentially an important mediator of higher CYP1A2 activity. CONCLUSIONS: Estimated CYP1A2 enzyme activity, and thus speed of caffeine metabolism, was higher in our type-2 diabetes group; this was possibly due to higher intake of caffeine, a known inducer of CYP1A2 enzyme activity. Given the fairly small sample sizes, the results need to be considered as preliminary and require validation in larger populations. PMID- 27713761 TI - Genome-Wide Identification, Phylogeny, and Expression Analyses of the 14-3-3 Family Reveal Their Involvement in the Development, Ripening, and Abiotic Stress Response in Banana. AB - Plant 14-3-3 proteins act as critical components of various cellular signaling processes and play an important role in regulating multiple physiological processes. However, less information is known about the 14-3-3 gene family in banana. In this study, 25 14-3-3 genes were identified from the banana genome. Based on the evolutionary analysis, banana 14-3-3 proteins were clustered into epsilon and non-epsilon groups. Conserved motif analysis showed that all identified banana 14-3-3 genes had the typical 14-3-3 motif. The gene structure of banana 14-3-3 genes showed distinct class-specific divergence between the epsilon group and the non-epsilon group. Most banana 14-3-3 genes showed strong transcript accumulation changes during fruit development and postharvest ripening in two banana varieties, indicating that they might be involved in regulating fruit development and ripening. Moreover, some 14-3-3 genes also showed great changes after osmotic, cold, and salt treatments in two banana varieties, suggested their potential role in regulating banana response to abiotic stress. Taken together, this systemic analysis reveals the involvement of banana 14-3-3 genes in fruit development, postharvest ripening, and response to abiotic stress and provides useful information for understanding the functions of 14-3-3 genes in banana. PMID- 27713763 TI - In-hospital costs of an admission for adhesive small bowel obstruction. AB - BACKGROUND: Previous research on the costs of treatment for ASBO is outdated and often based on reimbursements, rather than true healthcare provider costs of the admission and related interventions. An accurate estimate of the true costs of treatment is necessary to understand the healthcare burden and to model cost efficacy of adhesion strategies. The aim of this study was to provide an accurate cost estimate of the in-hospital costs for treatment of adhesive small bowel obstruction (ASBO) using micro-costing methods. METHODS: Consecutive patients admitted for ASBO to the Radboud University Medical Center from November 2013 to November 2015 were included. An episode of ASBO was defined as an admission for SBO with operative confirmation of adhesions or after radiological exclusion of other causes for SBO. For the purpose of generalization we used the costs of medication and interventions as provided by the Dutch Healthcare Authority and only if these were not available local hospital costs. We evaluated costs separately for operative and non-operative treatment for ASBO. RESULTS: During the study period 39 admissions for ASBO were eligible for analysis. An operative treatment was required in 19 patients (48.7 %). Mean hospital stay for ASBO with operative treatment was 16.0 +/- 11 days versus 4.0 +/- 2.0 days for non operative treatment (P = 0.003). A total of 12 patients developed complications, 2 in the non-operative group (10 %) and 10 in the operative group (52.6 %; P = 0.004). Overall costs for an admission for ASBO with operative treatment were ?16 305 (SD ?2 513), and for non-operative treatment ? 2 277 (SD ? 265) (p = <0.001). The highest expenditure with operative treatment for ASBO was made for ward stay (mean ?7 856, SD ?6 882), OR time (mean ?2 6845, SD ?1 434), ICU stay (mean ?2 183, SD ?4 305) and (parenteral) feeding costs (mean ?1797, SD ?2070). A table with correction coefficient to correct for differences in price levels for goods and services between different countries has been added. CONCLUSION: The in hospital costs of an admission for ASBO are higher than previously thought. These costs can be used to guide hospital reimbursement policy and for the development of a cost-effective model for the use of adhesion barriers. PMID- 27713766 TI - Recalcitrant carbohydrates after enzymatic hydrolysis of pretreated lignocellulosic biomass. AB - BACKGROUND: To reduce the cost of the enzymes for the hydrolysis of lignocellulosic biomass, two main strategies have been followed: one, the reduction of enzyme dosing by the use of more efficient and stable enzymatic cocktails; another, to include accessory enzymes in the cocktails to increase yields by reducing the recalcitrant carbohydrate fraction remaining at the end of the process. To guide this second strategy, we have explored the chemical bond composition of different fractions of recalcitrant carbohydrates after enzymatic hydrolysis. RESULTS: Two lignocellulosic feedstocks of relevance for the biofuels industry have been analyzed, corn stover and sugarcane straw. On comparing the composition of chemical bonds of the starting pretreated material with samples after standard and forced hydrolysis (with enzyme overdosing), we obtained similar sugar and chemical bond composition. CONCLUSIONS: This suggests that the current enzymatic cocktails bear the set of enzymes needed to hydrolyze these feedstocks. From our point of view, the results show the need for a parallel fine tuning of the enzymatic cocktails with the pretreatment process to maximize sugar release yield. PMID- 27713764 TI - Cognitive and behavioral risk factors for child physical abuse among Chinese children: a multiple-informant study. AB - BACKGROUND: It has been well established that child physical abuse is a risk factor for cognitive deficits and behavioral problems. However, the possible link between cognitive deficits and behavioral problems placing children at a higher risk of physical abuse has been overlooked. Using a prospective design, the present study aims to examine whether previously measured cognition indicated by intelligence quotient (IQ), including performance IQ (PIQ) and verbal IQ (VIQ), and behavioral problems reported by multiple informants (i.e. mothers, teachers, and children) predict later child physical abuse (which may include minor and severe forms of abuse inflicted separately by mothers and fathers) in Chinese children. METHODS: A school-based survey was conducted to collect data from 265 Chinese children (52.8 % boys, mean age 13.71 +/- 0.60 years) in the Wave II of China Jintan Cohort study. When they were in the last year of elementary school, children completed the Chinese version of the Wechsler intelligence scale for children-revised that measured VIQ and PIQ during 2010-2012 when their behaviors were self-assessed. Mothers and teachers of these children used the Chinese versions of the youth self report, the child behavior checklist and the teacher report form, respectively, to assess the children's behaviors. These children reported minor and severe physical abuse experiences in the previous 12 months from mothers and fathers separately using the Chinese version of parent-child conflict tactics scale in 2013 when children were in grades 7 and 8 of middle school. RESULTS: The present study found that after controlling for the sociodemographic and other cognitive and/or behavior variables, high scores of child externalizing behavior rated by their mothers or teachers were associated with increased risks of experiencing maternal and paternal severe physical abuse, while a high score of self-reported externalizing behavior was associated with a decreased risk of paternal severe physical abuse. A high score of mother-rated internalizing behavior was associated with a decreased risk of maternal severe physical abuse. VIQ was associated with maternal minor physical abuse with small effect size. PIQ was not associated with any forms of physical abuse after adjusting for child behavior and sociodemographic variables. CONCLUSIONS: In this community sample of Chinese children, externalizing behavior perceived by mothers and teachers is linked to children being at risk for physical abuse, while internalizing behavior perceived by mothers is associated with a decreased risk of maternal physical abuse. Findings suggest that educating parents and teachers to appropriately perceive children's externalizing behavior may help prevent the occurrence of physical abuse. PMID- 27713765 TI - Sleep and behavioural problems associate with low mood in Finnish children aged 4 12 years: an epidemiological study. AB - BACKGROUND: Few studies have examined the associations between sleep, mood and behaviour in young children in the early stages of developing psychopathology. The purpose here was to examine the association of emotional problems, especially mood, with family and child characteristics, sleep and behavioural problems in 4 12 year-old children. METHODS: The sample was population-based and included 1714 children. Parents filled in the Strengths and Difficulties Questionnaire and a background questionnaire on child and family characteristics. The associations between (a) emotional symptoms/mood and background variables, (b) emotional problems and conduct problems/hyperactivity and (c) mood and conduct problems/hyperactivity were examined with ordinal regression in univariate and multivariate models. RESULTS: Of the background variables, child's sleeping problems had the most powerful association with emotional symptoms and mood. Abnormal emotional problems score and emotional symptoms were associated with abnormal conduct problems and hyperactivity scores. Of the emotional symptoms, low mood was the one associated most strongly with conduct problems and hyperactivity after controlling for all significant background variables and other emotional symptoms. CONCLUSIONS: We conclude that in young children sleep problems associate with low mood. Low mood associates with behavioural problems. When a child presents with low mood or behavioural problems, a comprehensive assessment of their psychiatric symptoms, as well as their sleep problems, is recommended. PMID- 27713767 TI - Prenatal diagnosis of 1p34.3 interstitial microdeletion by aCGH in a fetus with jaw bone abnormalities. AB - BACKGROUND: Interstitial microdeletions in 1p are extremely rare, as very few cases have been reported postnatally and only one prenatally, yet. There is a variability of phenotypic findings such as hypotonia, facial dysmorphisms, mild microcephaly, with being most common developmental delay. CASE PRESENTATION: The present case involved a female fetus with an interstitial deletion on 1p, presenting with micrognathia in the 2nd trimester routine ultrasound examination. Array-based comparative genomic hybridization (a-CGH) revealed a 2,7 Mb deletion located on 1p34.3 which could not be detected by standard karyotyping. CONCLUSIONS: This is the first prenatal case of an interstitial deletion in 1p34.3 with facial dysmorphism detected by a-CGH. Due to the use of a-CGH techniques submicroscopic imbalances could be detected, and a refined genotype phenotype correlation could be achieved. PMID- 27713768 TI - Neurorehabilitation and Music. PMID- 27713769 TI - Stem cells and colorectal carcinogenesis. AB - Colorectal cancer represents an important cause of mortality and morbidity. Unfortunately, the physiopathology is still under study. There are theories about carcinogenesis and it is known that not only a single factor is responsible for the development of a tumor, but several conditions. Stem cells are a promising target for the treatment of colorectal cancer, along with the environment that has an important role. It has been postulated that mutations within the adult colonic stem cells may induce neoplastic changes. This theory is based on the observation that within a colon cancer, less than 1% of the neoplastic cells have the ability to regenerate the tumor and therefore they are responsible for recurrence. It is important to know that a new way of treatment needs to be found, since these cells are resistant to chemotherapy and radiotherapy. PMID- 27713771 TI - Iridociliary melanoma - Clinical case. AB - Iris and ciliary body melanoma is an aggressive tumor, which, unfortunately, presents symptoms only in advanced stages and is often discovered accidentally during a routine eye examination. There are several treatment options, ranging from in time monitorization in order to observe the tumor's evolution to more aggressive methods such as radiotherapy and enucleation. We present a case of iridociliary melanoma, who underwent conservative surgery, iridocyclectomy under scleral flap, with good results, and maintenance of the function and integrity of the eyeball.

PMID- 27713770 TI - The role of Vitamin D in immuno-inflammatory responses in Ankylosing Spondylitis patients with and without Acute Anterior Uveitis. AB - Hypothesis:Abnormal Vitamin D (Vit D) level could have consequences on the immuno inflammatory processes in Ankylosing Spondylitis (AS). Aim:The purpose of this study was to analyze the role of Vitamin D in the interplay between immune and inflammation effectors in AS associated-Acute Anterior Uveitis (AAU). Methods and Results:25-hydroxyvitamin D (Vit D), LL-37 peptide, IL-8 and Serum Amyloid A (SAA) were identified and quantified in the serum/ plasma of thirty-four AS patients [eleven AS patients presenting AAU (AAU AS patients) and twenty-three AS patients without AAU (wAAU AS patients)] and eighteen healthy individuals (Control) using enzyme-linked immunosorbent assay. Acute-phase SAA level was significantly higher in AS patients compared to Controls. Contrary with wAAU AS patients, significantly elevated levels of IL-8, and diminished levels of Vit D characterized AAU AS patients. Regarding LL-37, its level decreased concomitantly with the level of Vit D. When AS patients were subgrouped based on AAU presence or on Vit D level, important associations between immuno-inflammatory assessed markers and AS features were noticed. Generally, Vit D levels were associated indirectly with leukocytes/ neutrophils number or with ESR, CRP, and Fibrinogen levels. The levels of SAA and IL-8 associated directly with AAU or with AAU relapses, especially in AS patients with Vit D insufficiency, while SAA associated directly with infection/ inflammatory markers and with disease activity indexes or with the degree of functional limitation. Discussion:Altered levels of Vit D affect the balance between LL-37, IL-8 and SAA, suggesting an association with AAU, an extra-articular manifestation of AS. Abbreviations:Vit D = Vitamin D, AS = Ankylosing Spondylitis, AAU = Acute Anterior Uveitis, AAU AS = AS patients with AAU, wAAU AS = AS patients without AAU, SSZ = Sulphasalazine, Leu = Leukocytes, Neu = Neutrophils. PMID- 27713773 TI - Effect of diets supplemented with different conjugated linoleic acid (CLA) isomers on protein expression in C57/BL6 mice. AB - BACKGROUND: The individual genetic variations, as a response to diet, have recently caught the attention of several researchers. In addition, there is also a trend to assume food containing beneficial substances, or to supplement food with specific compounds. Among these, there is the conjugated linoleic acid (CLA), which has been demonstrated to reduce fat mass and to increase lean mass, even though its mechanism of action is still not known. We investigated the effect of CLA isomers (CLA c9,t11 and CLA t10,c12) on the proteomic profile of liver, adipose tissue, and muscle of mouse, with the aim of verifying the presence of a modification in fat and lean mass, and to explore the mechanism of action. METHODS: C57/BL6 mice were fed for 2 months with different diets: (1) standard chow, (2) CLA c9,t11 diet, (3) CLA t10,c11 diet, (4) CLA isomers mixture diet, and (5) linoleic acid diet. The proteomic profile of liver, white adipose tissue, and muscle was investigated. Statistical significance of the spots with an intensity higher than twofold in expression compared to the control was tested using student's t test (two-tail). RESULTS: We found that both isomers modulate the proteomic profiles of liver, adipose tissue, and muscle by different mechanisms of action. Liver steatosis is mostly due to the isomer CLA t10,c12, since it alters the expression of lipogenetic proteins; it acts also reducing the adipose tissue and increasing fatty acid oxidation in muscle. Conversely, CLA c9,t11 has no relevant effects on liver and adipose tissue, but acts mostly on muscle, where it enhances muscular cell differentiation. CONCLUSIONS: Administration of CLA in humans has to be carefully personalized, since even considering the presence of a species-specific effect, adverse effects might occur on long-term supplementation. Here we demonstrated that, in mouse, CLA is effective in reducing fat mass, but it also induces liver steatosis. The increase of lean mass is linked to an induction of cell proliferation, which, on long-term supplementation, might also lead to adverse effects. PMID- 27713774 TI - Alternative staging of regional lymph nodes in gastric cancer. AB - The TNM pN stage based on the number of metastatic lymph nodes is an independent prognostic factor in gastric cancer. Many studies have highlighted the phenomenon of stage migration and problems in comparing groups of patients with different numbers of total lymph nodes harvested within TNM staging. The current version of UICC/AJCC and JGCA TNM classifications postulates a minimal number of 16 lymph nodes as the base for N stage determination. Alternative systems such as lymph node ratio (LNR), positive to negative lymph node ratio (PNLNR), and LOGODDS (or LODDS), were implemented to increase the quality of LN assessment. These methods have reached the background in the literature, but to date no standard approach according to the cut-offs for the stages has been implemented. LOGODDS is the method that most reflects the number of harvested lymph nodes. The rationale for alternative staging methods, their correlations, and limitations are presented. PMID- 27713775 TI - Diet and Helicobacter pylori infection. AB - Helicobacter pylori infection has accompanied man for thousands of years. In some infected patients, a complex and dynamic pathogen-host reaction triggers pathogenic pathways resulting in development, inter alia, of atrophic gastritis, peptic ulcer disease (both gastric and duodenal), gastric adenocarcinoma, and MALT lymphoma. Large-scale eradication therapy is associated with a rapid increase in antibiotic resistance, gut flora composition disturbances, and increased risk of development, inter alia, of paediatric infectious diarrhoeas, atopic diseases, and oesophageal adenocarcinoma. Our diet contains many substances with potent antibacterial activity against H. pylori. Dietary interventions enable a decrease in H. pylori colonisation and result in a decrease in gastritis prevalence, thus potentially lowering the risk of gastric adenocarcinoma development.

AB - AIM: To evaluate the use of a double-channel gastroscope in patients with Billroth II gastrectomy to perform endoscopic retrograde cholangiopancreatography (ERCP) and interventions. MATERIAL AND METHODS: From January 2008 to December 2013, 18 patients with Billroth II gastrectomy were enrolled in this study. Endoscopic retrograde cholangiopancreatography was performed using a straight forward gastroscope with double working channel (4.2-mm diameter, 2.8-mm diameter). RESULTS: The success rate of selective cannulation and accomplishment of planned procedures was 15 out of 18 patients (83.3%), and no serious complications were encountered. CONCLUSIONS: The double-channel gastroscope appears to be useful in performing endoscopic retrograde cholangiopancreatography in patients with Billroth II gastrectomy. PMID- 27713778 TI - A comparison of two methods of treatment for central catheter tunnel phlegmon in home parenteral nutrition patients. AB - INTRODUCTION: The ESPEN guidelines on long-term (> 3 months) parenteral nutrition recommend the use of tunnelled central venous catheters (CVCs) to minimise the risk of insertion site infection. A developed symptomatic infection of the soft tissue tunnel surrounding a CVC may rapidly become directly life threatening if the infection progresses along the catheter tunnel towards its end inserted into the venous system. This requires immediate management to eliminate infection and limit its effects. AIM: To compare two surgical techniques for the treatment of suppurative inflammation of a CVC tunnel: conventional drainage of the infected tissues (surgical technique A) vs. radical en bloc excision of the infected tissues together with the infected central catheter (surgical technique B). MATERIAL AND METHODS: Seventy-three patients hospitalised due to CVC tunnel phlegmon between April 2004 and May 2014 were included in the retrospective study. Thirty-four (46.5%) patients underwent surgical procedure A and another 39 (53.5%) underwent procedure B. RESULTS: The mean duration of antibiotic therapy following procedure A was 8 +/-3 days, whereas procedure B required 7 +/-2 days of antibiotic therapy (NS). The mean hospitalisation period following procedure B was over 8 days shorter in comparison to that following procedure A (16.54 +/ 7.59 vs. 24.87 +/-10.19, p = 0.009, respectively). CONCLUSIONS: The surgical treatment of CVC tunnel phlegmon involving radical en bloc excision of suppurated tissues along with the infected CVC shortens hospitalisation, expedites the insertion of a new CVC, and potentially reduces treatment costs. PMID- 27713776 TI - Adjuvant, neoadjuvant, and experimental regimens in overcoming pancreatic ductal adenocarcinoma. AB - Pancreatic cancer is one of the most aggressive and deadly malignancies. Despite better understanding of its biology and pathogenesis, contemporary treatment regimens are still insufficient. Along with the introduction of new treatment agents and combination therapy, the response rates are increasing, but these scores do not go with overall survival, and results are frequently conflicting. Therefore, contemporary medicine faces the challenge of expanding the knowledge base and practice on all grounds - pathology, factor risk, diagnosis, and finally surgical and palliative treatment of this disease. This paper provides a review of current adjuvant and neoadjuvant regimens and the role of experimental therapies in pancreatic ductal adenocarcinoma. PMID- 27713779 TI - The impact of induction therapy with three doses of infliximab on deep histological healing in paediatric patients with active Crohn's disease. AB - INTRODUCTION: The clinical efficacy of infliximab (IFX) for induction of remission in both adults and children with active Crohn's disease (CD) has been well documented. Recently, so-called "deep remission" defined as mucosal healing has become the ultimate endpoint of the most recent therapeutic advances for CD. However, endoscopic evidence of mucosal healing is not necessarily associated with histological evidence of suppression of inflammation. AIM: Since data on that issue are limited, especially in the paediatric population, the aim of this study was to assess the impact of induction therapy with IFX on deep microscopic remission in paediatric patients with CD. MATERIAL AND METHODS: Fifty-six children (32 boys and 24 girls) aged 13.0 +/-9.3 years with moderate to severely active CD diagnosed at the mean age of 5.5 +/-0.83 years were included into the study. Colonoscopy and gastroscopy with sample collection were performed in all patients before and after three injections of IFX. Clinical activity of the disease was assessed using the Paediatric Crohn's Disease Activity Index (PCDAI), and the endoscopic activity was scored using the Simple Endoscopic Score (SES CD). Histological changes were evaluated by a previously described numerical scoring system. RESULTS: Thirty-nine (69.6%) patients reached clinical remission (PCDAI <= 10). When comparing data at baseline and at week 10, a significant decrease was observed in median PCDAI, and in SES-CD score between the initial and control colonoscopies. We also reported a decrease in histological scale. However, the difference was not statistically significant (p = 0.63). Three (5.4%) patients had a score of zero in the control histological examination. The correlation was found only between histological score and SES-CD score. Clinical remission correlated better with mucosal healing expressed by a decrease in SES CD score than with microscopic changes. CONCLUSIONS: Biological therapy with infliximab enables mucosal healing in paediatric patients with CD, which is not necessarily associated with histological evidence of suppression of inflammation. Mucosal healing correlates better than microscopic healing with clinical remission. PMID- 27713780 TI - Medium-chain triglycerides/long-chain triglycerides versus long-chain triglycerides in treatment of cancer patients with major body mass loss. Survival in patients with refractory cachexia. AB - INTRODUCTION: Currently there are no established guidelines regarding the use of long-chain triglycerides (LCT) vs. medium-chain triglycerides medium-chain triglycerides (MCT)/long-chain triglycerides (LCT) in total parenteral nutrition (TPN). Severe malnutrition of patients with refractory cachexia (RC) often causes their disqualification from invasive methods of treatment thus decreasing their quality of life and survival time. AIM: To compare the changes in nutritional state of patients with RC receiving PN with LCT and LCT/MCT lipid emulsions and to assess the influence of enteral nutrition on their survival time. MATERIAL AND METHODS: The study group comprised of 50 patients (23 female, 27 male) with a median age of 66 years. Refractory cachexia was diagnosed in them due to dysphagia secondary to solid tumours causing obstruction of the gastrointestinal tract (GT). All patients were qualified for surgical gastrostomy due to contraindications to percutaneous endoscopic gastrostomy. The patients were randomly assigned into one of two groups and perioperatively received either LCT or LCT/MCT. Blood samples were collected four times and tested for: total protein, albumin, prealbumin, and C-reactive protein concentration. Patients received Home Enteral Nutrition after discharge from hospital. RESULTS: Changes in nutritional status parameters were similar among patients receiving lipid emulsions LCT vs. MCT/LCT in TPN for 11 days. The mean survival time of all patients operated to gain enteral access to nutrition was 192 +/-268 days, and the median survival was 98 days. CONCLUSIONS: Regarding the short-term TPN, the results of the study do not demonstrate any superiority of MCT/LCT lipid emulsions over LCT, or vice versa. The inability to eat significantly accelerates unintended body mass loss among patients with RC. Disqualification from invasive treatment options deprives some patients of the benefits they might have obtained from the surgical access to GT and enteral nutrition.

AB - INTRODUCTION: Objective assessment of Crohn's disease (CD) activity in patients treated with anti-tumour necrosis factor (anti-TNF) antibodies is crucial for the prediction of its long-term results. Mucosal healing estimated endoscopically has a strong predictive value; however, only combined assessment together with transmural healing in magnetic resonance enterography (MRE) gives full information about the whole spectrum of inflammatory lesions in CD. AIM: To assess the usefulness of intestinal healing phenomenon in CD, defined as improvement both in endoscopy and MRE, after anti-TNF induction therapy, in predicting long-term results of 1-year treatment. MATERIAL AND METHODS: Twenty six patients with ileocolonic CD were enrolled into the study. In this group a parallel assessment of disease activity was estimated before and after induction doses of anti-TNF antibodies with ileocolonoscopy and MRE by using appropriate scores. Subsequently the patients were treated until 12 months and then followed up. The associations between intestinal healing (assessed in MRE and endoscopy), and mucosal and transmural healing with long-term results of 1-year anti-TNF therapy were analysed statistically. RESULTS: The median time of follow-up was 29 months (interquartile range - IQR: 14-46). Intestinal healing was significantly associated with favourable therapeutic outcomes (p = 0.02) and had 75% (IQR: 35 97%) sensitivity and 72% (IQR: 46-90%) specificity in predicting long-term remission. Other parameters were not useful (transmural healing) or their usefulness was of borderline significance (mucosal healing). CONCLUSIONS: Dynamic assessment of intestinal healing is an accurate method in predicting long-term outcomes in CD patients responding to 1-year anti-TNF therapy. PMID- 27713782 TI - Endoscopic therapy of oesophageal strictures in children - a multicentre study. AB - INTRODUCTION: Oesophageal strictures are rare in children but may require endoscopic dilation. AIM: To gather information on centres performing endoscopic oesophageal dilation in Poland. MATERIAL AND METHODS: The data were obtained from questionnaires concerning the relevant data mailed to 22 paediatric endoscopy centres. Completed questionnaires were received from 11 centres. RESULTS: In 2010 the 11 Polish paediatric endoscopy centres performed a total of 10,650 endoscopic procedures. This included 347 oesophageal dilations in 106 paediatric patients aged from 1 month to 18 years. The numbers of patients treated at individual centres ranged from 2 to 40. The indications for oesophageal dilation were as follows: postoperative strictures in 68 children, oesophageal burns in 17 children, postinflammatory strictures in 14 children, achalasia in 4 children, and strictures caused by a foreign body in 3 children. Rigid guidewire dilators were used in the majority of procedures (271), rigid dilators without a guidewire in 32 procedures, and balloon dilators in 45 procedures. A total of 203 procedures were conducted under fluoroscopic guidance, and 144 without the use of fluoroscopy. The number of dilating sessions performed in individual children varied from 1 to 6 and more. CONCLUSIONS: Oesophageal dilation constituted a minor proportion of all paediatric endoscopic procedures. The majority of children requiring dilation were patients up to 3 years of age with postoperative oesophageal strictures. In the majority of the centres rigid guidewire dilators were used, and in one third of the procedures these dilators were introduced without fluoroscopic guidance. PMID- 27713783 TI - The effect of standard therapy on mean platelet volume in patients with chronic hepatitis C. AB - INTRODUCTION: Chronic hepatitis C (CHC) infection is a systemic disorder that can lead to liver inflammation, fibrosis, cirrhosis, and hepatocellular cancer. The mean platelet volume (MPV) is widely used as an inflammatory marker to evaluate the platelet function and the status of systemic inflammation. AIM: To determine the pre- and post-treatment MPV values in CHC patients who were administered a 48 week antiviral therapy based on systemic inflammation. MATERIAL AND METHODS: We enrolled 28 patients, diagnosed with CHC genotype 1b, who received a 48-week antiviral therapy and attended regular follow-up, and 28 healthy individuals. In diagnosing CHC, a positive anti-HCV for a minimum duration of 6 months and a positive serum HCV RNA were accepted as the criteria. The patients were assigned to one of two groups based on their group 1 (pre-treatment values) and group 2 (post-treatment values) after 3 months therapy. We analysed and compared the blood samples of all of the groups. RESULTS: The MPV value was 8.89 +/-1.20 in group 1 and 8.00 +/-1.07 in group 2, and 8.21 +/-1.18 in the control group. The value in group 1 was detected to be statistically significantly different from that in group 2 and the control group (p < 0.0001, p = 0.045, respectively). No statistically significant difference was observed between group 2 and the control group (p = 0.455). CONCLUSIONS: The results of this study suggest that MPV could represent an inexpensive marker for use in assessing low-grade inflammation in patients with CHC. PMID- 27713784 TI - Cyanoacrylate application on colonic anastomosis: is it safe or not? AB - INTRODUCTION: Major complications of colonic anastomosis include fistula, bleeding, and anastomotic stricture, and the most common one is anastomotic leakage. Many organic or inorganic tissue adhesives are being used such as fibrin glue or cyanoacrylate to strengthen or protect colonic anastomosis. Up to now, a great number of studies have been carried out to investigate the effects of these biomaterials. AIM: To determine the effect of cyanoacrylate application on anastomosis safety. MATERIAL AND METHODS: In this experimental study, rats were divided into two groups; a control group and an experimental group. Full thickness incisions were done on the left colon of the rats, and then end-to-end anastomosis was performed by using 5/0 silk separated sutures. In the experimental group we applied cyanoacrylate over the sutures. The samples were taken on the 7th day. RESULTS: In the control group the average tissue hydroxyproline levels and the average bursting pressures were significantly higher than in the experimental group. CONCLUSIONS: The purpose of all the experimental studies is to prevent and reduce anastomotic complications. Despite all the studies that have been done, colonic anastomosis complications continue to be a problem. As a result, we suggest that cyanoacrylate has a negative effect on the healing process of colonic anastomosis.

AB - INTRODUCTION: Urology residency training in Canada is quickly evolving from a time-based to a competency-based model. We aim to better define core surgical competencies that would comprise a surgical curriculum and assess any discrepancies in opinion nationally. METHODS: A web-based survey was validated and sent to the 536 practicing members of the Canadian Urological Association (CUA) in August and October 2014. The survey consisted of questions regarding practice demographics, fellowship training, and evaluated the 76 most common urological procedures (using a five-point Likert scale) in the context of the question, "After completion of residency training in Canada a urologist should be proficient in..." A core procedure was defined as one for which there was >=75% agreement. Descriptive statistics and non-parametric testing were used to summarize the findings. RESULTS: A total of 138 urologists completed the survey (25.7% response rate) with representation from all geographic regions. Respondents included 40.6% community and 59.4% academic urologists. The survey identified 16 procedures with 90-100% agreement and a total of 30 core procedures with >=75% agreement. When comparing community and academic urologists, there was statistically significant disagreement on 27 procedures, including 11 core procedures, most notably cystectomy (88.5% agreement vs. 67.1%; p=0.002), open pyeloplasty (84.6% vs. 65.8%; p=0.04), simple prostatectomy (78.9% vs. 69.7%; p=0.03), perineal urethrostomy (80.8% vs. 67.1%; p=0.02), open radical prostatectomy (96.1% vs. 80.3%; p=0.007), and Boari flap (90.4% vs. 76.3%; p=0.004). Regional discrepancies were also found, demonstrating eight procedures deemed uniquely core and three core procedures deemed less important regionally. CONCLUSIONS: This national survey has provided some consensus on 30 procedures that should comprise a core surgical curriculum in urology. However, there are some key differences of opinion (most notably between community and academic urologists) that must be considered. PMID- 27713792 TI - CUA brochure readability: On the right track. PMID- 27713791 TI - An analysis of the readability of patient information materials for common urological conditions. AB - INTRODUCTION: Health literacy has been shown to be an important determinant of outcomes in numerous disease states. In an effort to improve health literacy, the Canadian Urological Association (CUA) publishes freely accessible patient information materials (PIMs) on common urological conditions. We sought to evaluate the readability of the CUA's PIMs. METHODS: All PIMs were accessed through the CUA website. The Flesch Reading Ease Score (FRES), the Flesch-Kincaid Grade Level (FKGL), and the number of educational graphics were determined for each PIM. Low FRES scores and high FKGL scores are associated with more difficult to-read text. Average readability values were calculated for each PIM category based on the CUA-defined subject categorizes. The five pamphlets with the highest FKGL scores were revised using word substitutions for complex multisyllabic words and reanalyzed. The Kruskal-Wallis test was used to identify readability differences between PIM categories and paired t-tests were used to test differences between FKGL scores before and after revisions. RESULTS: Across all PIMs, FRES values were low (mean 47.5, standard deviation [SD] 7.47). This corresponded to an average FKGL of 10.5 (range 8.1-12.0). Among PIM categories, the infertility and sexual function PIMs exhibited the highest average FKGL (mean 11.6), however, differences in scores between categories were not statistically significant (p=0.38). The average number of words per sentence was also highest in the infertility and sexual function PIMs and significantly higher than other categories (mean 17.2; p=0.01). On average, there were 1.4 graphics displayed per PIM (range 0-4), which did not vary significantly by disease state (p=0.928). Simple words substitutions improved the readability of the five most difficult-to read PIMs by an average of 3.1 grade points (p<0.01). CONCLUSIONS: Current patient information materials published by the CUA compare favourably to those produced by other organizations, but may be difficult to read for low-literacy patients. Readability levels must be balanced against the required informational needs of patients, which may be intrinsically complex. PMID- 27713793 TI - The impact of teaching on the duration of common urological operations. AB - INTRODUCTION: The ability of academic (teaching) hospitals to offer the same level of efficiency as non-teaching hospitals in a publicly funded healthcare system is unknown. Our objective was to compare the operative duration of general urology procedures between teaching and non-teaching hospitals. METHODS: We used administrative data from the province of Ontario to conduct a retrospective cohort study of all adults who underwent a specified elective urology procedure (2002-2013). Primary outcome was duration of surgical procedure. Primary exposure was hospital type (academic or non-teaching). Negative binomial regression was used to adjust relative time estimates for age, comorbidity, obesity, anesthetic, and surgeon and hospital case volume. RESULTS: 114 225 procedures were included (circumcision n=12 280; hydrocelectomy n=7221; open radical prostatectomy n=22 951; transurethral prostatectomy n=56 066; or mid-urethral sling n=15 707). These procedures were performed in an academic hospital in 14.8%, 13.3%, 28.6%, 17.1%, and 21.3% of cases, respectively. The mean operative duration across all procedures was higher in academic centres; the additional operative time ranged from 8.3 minutes (circumcision) to 29.2 minutes (radical prostatectomy). In adjusted analysis, patients treated in academic hospitals were still found to have procedures that were significantly longer (by 10-21%). These results were similar in sensitivity analyses that accounted for the potential effect of more complex patients being referred to tertiary academic centres. CONCLUSIONS: Five common general urology operations take significantly longer to perform in academic hospitals. The reason for this may be due to the combined effect of teaching students and residents or due to inherent systematic inefficiencies within large academic hospitals. PMID- 27713794 TI - Slower but safe? Resident involvement in urological surgeries. PMID- 27713795 TI - A survey of Canadian urologists' opinions and prescribing patterns of testosterone replacement therapy in men on active surveillance for low-risk prostate cancer. AB - INTRODUCTION: Attitudes regarding the safety of testosterone replacement therapy (TRT) in hypogonadal men with prostate cancer (PCa) have changed over the past few years with the emergence of case studies suggesting a low risk of cancer progression and a better understanding of the interaction of different levels of androgen with prostate cellular metabolism. This new view has the potential to change clinical practice. METHODS: Active members of the Canadian Urological Association were surveyed about their opinions on the safety of TRT in men with low-risk PCa, as well as their current prescribing habits. RESULTS: Of 57 responding urologists, 86% actively prescribe TRT in men with testosterone deficiency syndrome (TDS), 93% are involved in the treatment of men with PCa, and 95% offer active surveillance as a management option for low-grade/low-stage disease. Furthermore, 65% stated that they would offer TRT to men with TDS who were on active surveillance for PCa and 63% believed that TRT did not increase the risk of progression of PCa in these men. In terms of treatment methods, 96% believed TRT was safe for men who have undergone radical prostatectomy, while a smaller number felt it was safe for patients who have undergone brachytherapy (86%) or external beam radiation (84%). Despite these figures, only 35% of the surveyed physicians had ever offered TRT for men on active surveillance and only 42% actually had men in their practice who were taking testosterone while on active surveillance. CONCLUSIONS: The discrepancy between urologists' beliefs about the safety of TRT and their clinical practice patterns may be due to multiple factors, such as hesitation in recommending treatment in real-life practice, low numbers of eligible patients, absence of screening for testosterone deficiency in patients on active surveillance, and patient preference or fears. Furthermore, the difference in perceived safety in men treated by radical prostatectomy vs. radiation therapy suggests that some urologists are concerned that the radiated gland remaining in-situ may be "reactivated" by TRT. The results from this survey will be used as the basis of developing a national Canadian registry of men with low-grade/stage PCa who are receiving TRT while on active surveillance. PMID- 27713796 TI - Addressing the pressing issues related to testosterone administration to men with prostate cancer. PMID- 27713798 TI - Well-trained staff is the key to the success of urodynamic testing. PMID- 27713797 TI - Trained and dedicated staff appears to be the main factor in decreasing anxiety and improving overall satisfaction during urodynamic testing: A prospective, randomized trial. AB - INTRODUCTION: We sought to determine whether listening to patient-selected music during urodynamic study (UDS) reduced pain and anxiety while increasing overall patient satisfaction and willingness to repeat the procedure. METHODS: Fifty-one (51) patients who underwent UDS from March to July 2014 were randomized into two groups: Group 1 with patient-selected music during the procedure (n=27) and Group 2 without music (n=24). Standard multichannel filling cystometry was performed. Anxiety was self-assessed using the State Trait Anxiety Inventory, while overall pain, satisfaction, and willingness to undergo the procedure again were self measured using a visual analogue scale. RESULTS: Demographic characteristics and reasons for testing were similar between the two groups. The state score for Groups 1 and 2 were 27.04 and 29.5, respectively (p=0.3225) and 31.78 and 33.86, respectively (p=0.4970) for the trait score. The mean pain scores were 1.04 and 1.57, respectively (p=0.2047); the mean satisfaction scores were 0.65 and 0.52, respectively (p=0.8169); and the scores for willingness to undergo the procedure again were 0.77 and 0.74, respectively (p=0.9442). While there were no significant differences between the two groups in anxiety and satisfaction scores, pain, and willingness to undergo the procedure again, both groups commented on the nurse as the most important factor in their overall comfort. CONCLUSIONS: Music during UDS did not appear to lower pain and anxiety, nor increase overall satisfaction and willingness to repeat the procedure. The most important aspect in alleviating patients' pain and anxiety was the person actually performing the testing, highlighting the importance of having trained and dedicated staff. PMID- 27713800 TI - Robotic prostatectomy and access to care: Canadian vs. U.S. experience. PMID- 27713799 TI - Robotic prostatectomy is associated with increased patient travel and treatment delay. AB - INTRODUCTION: New technologies may limit access to treatment. We investigated radical prostatectomy (RP) access over time since robotic introduction and the impact of robotic use on RP access relative to other approaches in the modern era. METHODS: Using the National Cancer Data Base, RPs performed during the eras of early (2004-2005) and late (2010-2011) robotic dissemination were identified. The primary endpoints, patient travel distance and treatment delay, were compared by era, and for 2010-2011, by surgical approach. Analyses included multivariable and multinomial logistic regression. RESULTS: 138 476 cases were identified, 32% from 2004-2005 and 68% from 2010-2011. In 2010-2011, 74%, 21%, and 4.3% of RPs were robotic, open, and laparoscopic, respectively. Treatment in 2010-2011 and robotic approach were independently associated with increased patient travel distance and longer treatment delay (p<0.001). Men treated robotically had 1.1 1.2 times higher odds of traveling medium-to-long-range distances and 1.2-1.3 higher odds of delays 90 days or greater compared to those treated open (p<0.001). Laparoscopic approach was associated with increased patient travel and treatment delay, but to a lesser extent than the robotic approach (p<0.001). In high-risk patients, treatment delays remained significantly longer for minimally invasive approaches (p<0.001). Other factors associated with the robotic approach included referral from an outside facility, treatment at an academic or high volume hospital, higher income, and private insurance. Potential limitations include the retrospective observational design and lack of external validation of the primary outcomes. CONCLUSIONS: The robotic approach is associated with increased travel burden and treatment delay, potentially limiting access to surgical care. PMID- 27713801 TI - The association between institution at orchiectomy and outcomes on active surveillance for clinical stage I germ cell tumours. AB - INTRODUCTION: Institutional experience has been associated with improved outcomes for various malignancies, including testicular cancer. The present study evaluated whether institution at orchiectomy was associated with outcomes on active surveillance (AS) for clinical stage (CS) I germ cell tumours (GCT). METHODS: 815 patients with CSI GCT managed with AS at the Princess Margaret Cancer Centre were identified. Princess Margaret is a tertiary academic institution with a multidisciplinary testicular cancer clinic involving radiation oncologists, medical oncologists, and urologists, and has research experience in testicular cancer care. The association between institution of orchiectomy (Princess Margaret vs. Other) and time to progression on AS was analyzed using multivariable Cox proportional hazards models. Academic vs. non-academic institutions were compared in a sensitivity analysis. RESULTS: Patients undergoing orchiectomy at Princess Margaret for non-seminoma GCT were significantly less likely to have pure embryonal carcinoma (EC) in orchiectomy pathology (odds ratio [OR] 0.33; p=0.008) and CSIB disease (OR 0.47; p=0.014). Seminoma characteristics did not differ significantly between institution groups. In non-seminoma GCT, median followup was 5.4 years, 27% progressed on AS, and institution of orchiectomy was not associated with time to progression in either univariate (hazard ratio [HR] 0.79; p=0.33) or multivariable analyses (HR 1.01; p=0.97). In seminoma, median followup was 4.7 years, 12% progressed on AS, and institution of orchiectomy was not associated with progression (univariate: HR 0.87; p=0.73; multivariable: HR 0.98; p=0.96). Sensitivity analyses demonstrated similar results. CONCLUSIONS: Among CSI GCT patients managed on AS at a specialized cancer centre, there appears to be no difference in oncologic outcomes based upon the institution where orchiectomy was performed.

AB - Urinary tract infections (UTIs) represent a common bacterial cause of febrile illness in children. Of children presenting with a febrile UTI, 25-40% are found to have vesicoureteral reflux (VUR). Historically, the concern regarding VUR was that it could lead to recurrent pyelonephritis, renal scarring, hypertension, and chronic kidney disease. As a result, many children underwent invasive surgical procedures to correct VUR. We now know that many cases of VUR are low-grade and have a high rate of spontaneous resolution. The roles of surveillance, antibiotic prophylaxis, endoscopic injection, and ureteral reimplantation surgery also continue to evolve. In turn, these factors have influenced the investigation of febrile UTIs. Voiding cystourethrography (VCUG) is the radiographic test of choice to diagnose VUR. Due to its invasive nature and questionable benefit in many cases, the American Academy of Pediatrics (AAP) no longer recommends VCUG routinely after an initial febrile UTI. Nevertheless, these guidelines pre-date the landmark Randomized Intervention of Children with Vesicoureteral Reflux (RIVUR) trial and there continues to be controversy regarding the diagnosis and management of VUR. This paper discusses the current literature regarding radiographic testing in children with febrile UTIs and presents a practical risk based approach for deciding when to obtain a VCUG. PMID- 27713804 TI - Cognitive Enhancement Therapy Improves Resting-State Functional Connectivity in Early Course Schizophrenia. AB - OBJECTIVE: Cognitive remediation is emerging as an effective psychosocial intervention for addressing untreated cognitive and functional impairments in persons with schizophrenia, and might achieve its benefits through neuroplastic changes in brain connectivity. This study seeks to examine the effects of cognitive enhancement therapy (CET) on fronto-temporal brain connectivity in a randomized controlled trial with individuals in the early course of schizophrenia. METHOD: Stabilized, early course outpatients with schizophrenia or schizoaffective disorder (N = 41) were randomly assigned to CET (n = 25) or an active enriched supportive therapy (EST) control (n = 16) and treated for 2 years. Functional MRI data were collected annually, and pseudo resting-state functional connectivity analysis was used to examine differential changes in fronto-temporal connectivity between those treated with CET compared with EST. RESULTS: Individuals receiving CET evidenced significantly less functional connectivity loss between the resting-state network and the left dorsolateral prefrontal cortex as well as significantly increased connectivity with the right insular cortex compared to EST (all corrected p < .01). These neural networks are involved in emotion processing and problem-solving. Increased connectivity with the right insula significantly mediated CET effects on improved emotion perception (z' = -1.96, p = .021), and increased connectivity with the left dorsolateral prefrontal cortex mediated CET-related improvements in emotion regulation (z' = -1.71, p = .052). CONCLUSIONS: These findings provide preliminary evidence that CET, a psychosocial cognitive remediation intervention, may enhance connectivity between frontal and temporal brain regions implicated in problem-solving and emotion processing in service of cognitive enhancement in schizophrenia. PMID- 27713805 TI - Vitamin D Supplementation and High-Density Lipoprotein Cholesterol: A Study in Healthy School Children. AB - BACKGROUND: The high-density lipoprotein cholesterol (HDL-C) level has been shown to have a significant role in the prevention of cardiovascular diseases and atherosclerosis. Low vitamin D levels have been shown to be correlated with dyslipidemia, but limited data exist on indigenous children. OBJECTIVES: We aimed to investigate the effect of vitamin D supplementation on HDL-C levels in school aged Iranian children. METHODS: In this prospective controlled clinical trial, 47 healthy children (23 boys) aged 10 - 14 years, students of Birjand (Iran) elementary schools, were selected and randomly divided into two groups. The study group received a vitamin D supplement (1000 mg capsule) daily for one month, and placebo tablets were prescribed to the controls. Before and after the treatment course, the serum HDL-C and 25-hydroxy vitamin D levels of both groups were measured. The data were analyzed by SPSS, ver. 16, and Chi-square tests, Fisher's exact test, paired-sample t-tests, and Pearson's correlation were used, wherever appropriate. The significance level was set at P < 0.05. RESULTS: Forty children completed the study; their mean age was 11.5 +/- 1.175 years. The mean serum levels of both HDL-C and vitamin D showed a significant rise following the treatment in the study group (P = 0.007 and P < 0.001, respectively), whereas both variables decreased slightly in the control group (P = 0.27). There was no statistically significant difference in the mean serum levels of HDL-C and vitamin D between the two groups after the intervention (P = 0.11 and P = 0.20, respectively). CONCLUSIONS: Vitamin D supplements seem to have a positive impact on serum HDL-C levels and may be effective in reducing the risk of cardiovascular diseases in the long term. PMID- 27713807 TI - The Diagnostic Significance of Comorbidities of Congenital Heart Diseases, Low Set Ears, and Intrauterine Growth Restriction in Neonates With Trisomies 13 and 18. AB - BACKGROUND: Trisomies 13 and 18 (T13/18) are autosomal trisomy syndromes with dismal prognoses. Deciding whether to perform a chromosomal analysis for the definitive diagnosis is often difficult (even for experienced pediatricians) because representative clinical signs may not be found in all T13/18 neonates. OBJECTIVES: This study aimed to investigate any clinical signs that could be useful for screening for T13/18 in participants without the representative clinical signs traditionally found in odd-looking neonates with malformation syndromes. PATIENTS AND METHODS: We retrospectively analyzed 15 T13/18 patients, 33 trisomy 21 patients, and 48 controls with other malformation syndromes, for apparent clinical signs during the neonatal period. All participants had been admitted to the neonatal intensive care unit of Kansai Medical University over a nine-year period. RESULTS: The three leading clinical signs in patients with T13/18 were congenital heart diseases (CHD; 100%), low-set ears (LSE; 80%), and intrauterine growth restriction (IUGR; 73.3%). A comorbidity of these two leading non-specific clinical signs was CHD with LSE, which showed the highest diagnostic accuracy between T13/18 and controls with a sensitivity of 80.0% and a negative predictive value of 92.5%. The chi-square test among these three groups (P < 0.01) and multiple comparison tests of proportional differences showed that the comorbidity of CHD with LSE was specific for autosomal trisomy syndromes. A comorbidity of CHD with IUGR also revealed a similar diagnostic accuracy with a sensitivity of 73.3% and a negative predictive value of 90.9% as well as a specificity for T13/18. CONCLUSIONS: The comorbidities of either CHD with LSE or CHD with IUGR should be suspected in neonates with autosomal trisomy syndromes, particularly T13/18 without the expected representative clinical signs. PMID- 27713806 TI - Obese Chinese Primary-School Students and Low Self-Esteem: A Cross-Sectional Study. AB - OBJECTIVES: The aim of this study was to examine several factors related to low self-esteem among obese Chinese primary-school students. METHODS: A cross sectional study was conducted between June 2009 and June 2010. A total of 1,410 primary-school students (China grades 4 - 6) in Changsha city were divided into normal weight (n = 1,084), overweight (n = 211), and obese groups (n = 115) according to world health organization (WHO) growth standards for body mass index (BMI). The students were assessed using the self-esteem scale (SES) and a general situation questionnaire. Caregivers completed questionnaires about their child's weight status. Self-esteem levels were explored; any factors related to low self esteem were analyzed using logistic regression analysis. RESULTS: The average self-esteem score among overweight or obese primary-school students was found to be lower than that of normal-weight students. The proportion of students with low self-esteem in the obese group was more than that in the normal-weight and overweight groups. Multiple logistic regression analysis showed that obesity status (odds ratio [OR], 3.74; 95% confidence interval [CI], 2.25 - 6.22), overweight status (OR, 2.60; 95% CI, 1.71 - 3.95), obesity considered by children's grandparents (OR, 1.76; 95% CI, 1.05 - 2.96), dissatisfaction with height (OR, 1.55; 95% CI, 1.11 - 2.18), and dissatisfaction with weight (OR, 1.45; 95% CI, 1.05 - 2.01) were the risk factors for low self-esteem for primary school students, while satisfaction with academic performance was a protective factor (OR, 0.22; 95% CI, 0.07 - 0.71). CONCLUSIONS: For Chinese primary-school students, low self-esteem is associated with higher weight status and self perceived body shape and academic performance. In addition, grandparental opinion of a child's weight also contributes to low self-esteem. PMID- 27713808 TI - Depressor Anguli Oris in IVF Twins. PMID- 27713809 TI - Comparison of Oral Acetaminophen Versus Ibuprofen in Premature Infants With Patent Ductus Arteriosus. AB - BACKGROUND: Patent ductus arteriosus (PDA) is a common cause of morbidity. The aim of this study was to compare the efficacy of oral Acetaminophen and oral Ibuprofen for the closure of patent ductus arteriosus (PDA) in preterm infants. OBJECTIVES: This study demonstrated that, there was no significant difference between treatment of PDA with either oral Acetaminophen or oral Ibuprofen in preterm neonates. PATIENTS AND METHODS: This clinical trial, randomized study, enrolled 120 infants, with a gestational age of < 37 weeks, who were admitted in neonatal intensive care unit of Afzalipour hospital, Kerman, Iran, in 2014. PDA was confirmed echocardiographically. The trial was registered in Iranian registry of clinical trials (Reg. No. 25542). Sixty-seven infants received oral Acetaminophen (15mg/kg every six hours for three days) and 62 infants received Ibuprofen (an initial dose of 20 mg/kg, followed by 10 mg/kg at 24 and 48 hours). To evaluate the efficacy of the treatment, a second echocardiography was done after completing the treatment. RESULTS: After the first course of the treatment, PDA closed in 55 (82.1 %) patients who received oral Acetaminophen vs. 47 (75.8 %) of those given oral Ibuprofen (P = 0.38). After the second course of treatment, PDA closed in 50 % of oral Acetaminophen group and 73.3% of oral Ibuprofen group (P = 0.21). CONCLUSIONS: This study demonstrated that, there was no significant difference between treatment of PDA with either oral Acetaminophen or oral Ibuprofen in preterm neonates. Oral Ibuprofen can effectively close PDA but is unfortunately associated with some adverse effects limiting its utility thus we studied an alternative drug with similar efficacy and less adverse effects. This study has recommends Acetaminophen with minimal complications for the treatment of PDA in preterm neonates instead of Ibuprofen. PMID- 27713810 TI - The Clinical Course of Patients With Atrial Septal Defects. AB - BACKGROUND: Atrial septal defect (ASD) is a common congenital heart disease. OBJECTIVES: The aim of this study was to assess the clinical course of ASD, as well as its frequency of spontaneous closure and regression of diameter. METHODS: In a study conducted from 2000 to 2011, 192 consecutive patients with an isolated ASD were followed up regularly with periodic echocardiographic evaluations according to a standardized protocol. The study was conducted in two series of patients: infants and children and adults. Infants were classified into three groups based on ASD diameter: small (<= 5 mm), medium (6 - 9 mm), and large (> 9 mm). In the same manner, the ASD size in children and adults was categorized into three groups: small (<= 10), medium (10 - 20 mm), and large (> 20 mm). RESULTS: The patients consisted of 76 (39.6%) males and 116 (60.4%) females. The mean age of patients at diagnosis was 16.12 +/- 15.66 years (range 1 week - 75 years). The mean follow-up duration was 70 +/- 9 months (range: 25 - 119 months). The most prevalent age group was adult patients (> 20 years), and most ASDs were of medium size (1 - 2 cm). The most common complication was mild pulmonary hypertension (31 cases, 16.2%), and Eisenmenger phenomenon was the rarest complication (2 cases, 1%). Overall spontaneous closure of ASD occurred in 42 (21.9%) cases. Spontaneous closure in cases with small defects occurred in 18 of 22 (81%) infants and 24 of 81 children > 1 years of age. Regression of ASD size occurred in 2 (9.5%) infants and 3 (3.7%) children. No spontaneous closure was observed in cases with a defect size > 10 mm, and no spontaneous occlusion was detected in adolescents or adults. Seventy-two percent (n = 139) of patients needed surgical repair or transcatheter closure of the ASD. CONCLUSIONS: It is concluded that atrial septal defects < 6 mm typically close spontaneously, and ASDs measuring 6 - 9 mm may regress in infants and children. An ASD > 1 cm has little chance of spontaneous closure and may need surgical or device closure. ASD diameter and age at diagnosis are the most important predictors of spontaneous closure and the need for possible surgical or device closure. PMID- 27713811 TI - High-Normal Arterial Blood Pressure in Children With Excess Body Weight. AB - BACKGROUND: Childhood overweight and obesity are common causes of metabolic disorders that persist until adulthood. OBJECTIVES: The purpose of this study was to determine the prevalence of high-normal arterial blood pressure (ABP) in children with excess body weight. MATERIAL AND METHODS: A total of 1,093 schoolchildren aged 10 - 12 years (51% girls and 49% boys) participated in the study. The children's weight, height, body fat percentage (BFP), waist and hip circumference, and ABP were measured. The waist-to-height ratio (WHtR) and body mass index (BMI) were calculated and compared to the normative reference values accepted by the International obesity task force (IOTF). RESULTS: Excess weight was identified in 20% of the participants, and obesity in 5%. A total of 35.5% of overweight children had above-normal ABP, which implied hypertension. In obese children, that proportion equaled 59.3%. BFP was 6.5% greater in children with hypertension than in those with normal BP. The children with hypertension also had a 7.6-cm larger waist circumference, a 7.6-cm larger hip circumference, and a greater WHtR (by 0.04). CONCLUSIONS: Excess body weight was identified in 25% of children aged 10 - 12 years, significantly increasing their risk of developing hypertension. PMID- 27713812 TI - Relationship Between the Presence of Eczema Herpeticum and the Significance of Clinical and Laboratory Tests in Korean Children With Atopic Dermatitis. AB - BACKGROUND: Eczema herpeticum (EH) is a herpes simplex virus (HSV) infection superimposed on atopic dermatitis (AD). OBJECTIVES: The aim of this study was to evaluate the relationship between clinical features and laboratory tests, including skin cultures, total IgE, eosinophil count, eosinophil cationic protein, and 25-hydroxyvitamin D3 (25-(OH)D3), in Korean children with AD according to the presence of EH. PATIENTS AND METHODS: We enrolled 380 patients aged 6 months to 18 years who were admitted to Busan St. Mary's hospital from January 2012 to December 2014. All 380 subjects were divided into two groups: the control and the AD group. The AD group was further divided into two subgroups: EH+ and EH-. RESULTS: The male gender was related to the presence of EH (odds ratio of 2.56; 95% confidence interval, 1.19 - 5.53, P = 0.01), but age and 25 (OH)D3 levels were not. After adjusting for age, gender, and 25-(OH)D3, no significant relationship was found between total IgE, eosinophil cationic protein or eosinophil count levels and the presence of EH. The relationship between positive skin cultures and the presence of EH was significant (P < 0.001) and the presence of methicillin-resistant Staphylococcus aureus (MRSA) was also related to the development of EH (OR, 0.19; 95% CI, 0.04 - 0.92, P = 0.03). CONCLUSIONS: We conclude that while male gender, positive skin culture results, and the presence of MRSA are factors influencing EH, serum 25-(OH)D3 levels are not associated with EH in Korean AD children.

PMID- 27713815 TI - Altered functional organization within the insular cortex in adult males with high-functioning autism spectrum disorder: evidence from connectivity-based parcellation. AB - BACKGROUND: The insular cortex comprises multiple functionally differentiated sub regions, each of which has different patterns of connectivity with other brain regions. Such diverse connectivity patterns are thought to underlie a wide range of insular functions, including cognitive, affective, and sensorimotor processing, many of which are abnormal in autism spectrum disorder (ASD). Although past neuroimaging studies of ASD have shown structural and functional abnormalities in the insula, possible alterations in the sub-regional organization of the insula and the functional characteristics of each sub-region have not been examined in the ASD brain. METHODS: Resting-state functional magnetic resonance imaging (rs-fMRI) data were acquired from 36 adult males with ASD and 38 matched typically developed (TD) controls. A data-driven clustering analysis was applied to rs-fMRI data of voxels in the left and right insula to automatically group voxels with similar intrinsic connectivity pattern into a cluster. After determining the optimal number of clusters based on information theoretic measures of variation of information and mutual information, functional parcellation patterns in both the left and the right insula were compared between the TD and ASD groups. Furthermore, functional profiles of each sub-region were meta-analytically decoded using Neurosynth and were compared between the groups. RESULTS: We observed notable alterations in the anterior sector of the left insula and the middle ventral sub-region of the right insula in the ASD brain. Meta-analytic decoding revealed that whereas the anterior sector of the left insula contained two functionally differentiated sub-regions for cognitive, sensorimotor, and emotional/affective functions in TD brain, only a single functional cluster for cognitive and sensorimotor functions was identified in the anterior sector in the ASD brain. In the right insula, the middle ventral sub region, which is primarily specialized for sensory- and auditory-related functions, showed a significant volumetric increase in the ASD brain compared with the TD brain. CONCLUSIONS: The results indicate an altered organization of sub-regions in specific parts of the left and right insula of the ASD brain. The alterations in the left and right insula may constitute neural substrates underlying abnormalities in emotional/affective and sensory functions in ASD. PMID- 27713816 TI - CGG-repeat dynamics and FMR1 gene silencing in fragile X syndrome stem cells and stem cell-derived neurons. AB - BACKGROUND: Fragile X syndrome (FXS), a common cause of intellectual disability and autism, results from the expansion of a CGG-repeat tract in the 5' untranslated region of the FMR1 gene to >200 repeats. Such expanded alleles, known as full mutation (FM) alleles, are epigenetically silenced in differentiated cells thus resulting in the loss of FMRP, a protein important for learning and memory. The timing of repeat expansion and FMR1 gene silencing is controversial. METHODS: We monitored the repeat size and methylation status of FMR1 alleles with expanded CGG repeats in patient-derived induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) that were grown for extended period of time either as stem cells or differentiated into neurons. We used a PCR assay optimized for the amplification of large CGG repeats for sizing, and a quantitative methylation-specific PCR for the analysis of FMR1 promoter methylation. The FMR1 mRNA levels were analyzed by qRT-PCR. FMRP levels were determined by western blotting and immunofluorescence. Chromatin immunoprecipitation was used to study the association of repressive histone marks with the FMR1 gene in FXS ESCs. RESULTS: We show here that while FMR1 gene silencing can be seen in FXS embryonic stem cells (ESCs), some silenced alleles contract and when the repeat number drops below ~400, DNA methylation erodes, even when the repeat number remains >200. The resultant active alleles do not show the large step-wise expansions seen in stem cells from other repeat expansion diseases. Furthermore, there may be selection against large active alleles and these alleles do not expand further or become silenced on neuronal differentiation. CONCLUSIONS: Our data support the hypotheses that (i) large expansions occur prezygotically or in the very early embryo, (ii) large unmethylated alleles may be deleterious in stem cells, (iii) methylation can occur on alleles with >400 repeats very early in embryogenesis, and (iv) expansion and contraction may occur by different mechanisms. Our data also suggest that the threshold for stable methylation of FM alleles may be higher than previously thought. A higher threshold might explain why some carriers of FM alleles escape methylation. It may also provide a simple explanation for why silencing has not been observed in mouse models with >200 repeats. PMID- 27713818 TI - Awareness of radiographic guidelines for low back pain: a survey of Australian chiropractors. AB - BACKGROUND: Chiropractors have been shown to refer for lumbar radiography in clinical scenarios inconsistent with the current clinical guidelines for low back pain. It is unknown whether this is due to lack of adherence with known guidelines or a lack of awareness of relevant guidelines. Therefore, the aim of this study is to determine Australian chiropractors' awareness of, and reported adherence to, radiographic guidelines for low back pain. Demographic, chiropractic practice and radiographic usage characteristics will be investigated for association with poor guideline adherence. METHODS: An online survey was distributed to Australian chiropractors from July to September, 2014. Survey questions assessed demographic, chiropractic practice and radiographic usage characteristics, awareness of radiographic guidelines for low back pain and the level of agreement with current guidelines. Results were analysed with descriptive statistics and logistic regression analysis. RESULTS: There were 480 surveys completed online. Only 49.6 % (95 % confidence interval (95 % CI): 44.9, 54.4) reported awareness of radiographic guidelines for low back pain. Chiropractors reported a likelihood of referring for radiographs for low back pain: in new patients (47.6 % (95 % CI: 42.9, 52.3)); to confirm biomechanical pathologies (69.0 % (95 % CI: 64.5, 73.1)); to perform biomechanical analysis (37.5 % (95 % CI: 33.1, 42.0)); or to screen for contraindications (39.4 % (95 % CI: 35.0, 44.0)). Chiropractors agreed that radiographs for low back pain could be useful for: acute low back pain (54.0 % (95 % CI: 49.2, 58.7)); screening for contraindications (55.8 % (95 % CI: 51.0, 60.5)); or to confirm diagnosis and direct treatment (61.3 % (95 % CI: 56.5, 65.9)). Poorer adherence to current guidelines was seen if the chiropractor referred to in-house radiographic facilities, practiced a technique other than diversified technique or was unaware or unsure of current radiographic guidelines for low back pain. CONCLUSION: Only 50 % of Australian chiropractors report awareness of current radiographic guidelines for low back pain. A poorer awareness of guidelines is associated with an increase in the reported likelihood of use, and the perceived usefulness of radiographs for low back pain, in clinical situations that fall outside of current guidelines. Therefore, education strategies may help to increase guideline knowledge and compliance. PMID- 27713817 TI - VAChT overexpression increases acetylcholine at the synaptic cleft and accelerates aging of neuromuscular junctions. AB - BACKGROUND: Cholinergic dysfunction occurs during aging and in a variety of diseases, including amyotrophic lateral sclerosis (ALS). However, it remains unknown whether changes in cholinergic transmission contributes to age- and disease-related degeneration of the motor system. Here we investigated the effect of moderately increasing levels of synaptic acetylcholine (ACh) on the neuromuscular junction (NMJ), muscle fibers, and motor neurons during development and aging and in a mouse model for amyotrophic lateral sclerosis (ALS). METHODS: Chat-ChR2-EYFP (VAChTHyp) mice containing multiple copies of the vesicular acetylcholine transporter (VAChT), mutant superoxide dismutase 1 (SOD1G93A), and Chat-IRES-Cre and tdTomato transgenic mice were used in this study. NMJs, muscle fibers, and alpha-motor neurons' somata and their axons were examined using a light microscope. Transcripts for select genes in muscles and spinal cords were assessed using real-time quantitative PCR. Motor function tests were carried out using an inverted wire mesh and a rotarod. Electrophysiological recordings were collected to examine miniature endplate potentials (MEPP) in muscles. RESULTS: We show that VAChT is elevated in the spinal cord and at NMJs of VAChTHyp mice. We also show that the amplitude of MEPPs is significantly higher in VAChTHyp muscles, indicating that more ACh is loaded into synaptic vesicles and released into the synaptic cleft at NMJs of VAChTHyp mice compared to control mice. While the development of NMJs was not affected in VAChTHyp mice, NMJs prematurely acquired age-related structural alterations in adult VAChTHyp mice. These structural changes at NMJs were accompanied by motor deficits in VAChTHyp mice. However, cellular features of muscle fibers and levels of molecules with critical functions at the NMJ and in muscle fibers were largely unchanged in VAChTHyp mice. In the SOD1G93A mouse model for ALS, increasing synaptic ACh accelerated degeneration of NMJs caused motor deficits and resulted in premature death specifically in male mice. CONCLUSIONS: The data presented in this manuscript demonstrate that increasing levels of ACh at the synaptic cleft promote degeneration of adult NMJs, contributing to age- and disease-related motor deficits. We thus propose that maintaining normal cholinergic signaling in muscles will slow degeneration of NMJs and attenuate loss of motor function caused by aging and neuromuscular diseases. PMID- 27713820 TI - Fibromyalgia syndrome: metabolic and autophagic processes in intermittent cold stress mice. AB - Fibromyalgia is characterized by widespread musculoskeletal pain, fatigue, and depression. The aim was to analyze potential mitochondrial dysfunction or autophagy in mice after exposure to intermittent cold stress (ICS). Muscle and liver specimens were obtained from 36 mice. Lactate dehydrogenase (LDH) activity was measured. Microtubule-associated protein light chain 3 (MAP1LC3B) and glycogen content were determined histologically; muscle ultrastructure by electron microscopy. Mitochondrial- and autophagy-related markers were analyzed by RT-qPCR and Western blotting. ATP level, cytotoxicity, and caspase 3 activity were measured in murine C2C12 myoblasts after ICS exposure. Coenzyme Q10B (COQ10B) transcript was up-regulated in limb muscle of ICS mice, whereas its protein content was stable. Cytochrome C oxidase 4 (COX4I1) and LDH activity increased in limb muscle of male ICS mice. Glycogen content was lower in muscle and liver tissue of male ICS mice. Electron micrographs of ICS mice specimens showed mitochondrial damage and autophagic vesicles. A significant up-regulation of autophagic transcripts of MAP1LC3B and BECLIN 1 (BECN1) was observed. Map1lc3b protein showed an aggregated distribution in ICS mice and SqSTM1/p62 (p62) protein level was stable. Furthermore, ATP level and caspase activity, detected as apoptotic marker, were significantly lowered after ICS exposure in differentiated C2C12 myoblasts. The present study shows that ICS mice are characterized by mitochondrial dysfunction, autophagic processes, and metabolic alterations. Further investigations could dissect autophagy process in the proposed model and link these mechanisms to potential therapeutic options for fibromyalgia. PMID- 27713821 TI - RGS14 regulates the lifetime of Galpha-GTP signaling but does not prolong Gbetagamma signaling following receptor activation in live cells. AB - RGS14 is a multifunctional scaffolding protein possessing two distinct G protein interaction sites including a regulator of G protein signaling (RGS) domain that acts as a GTPase activating protein (GAP) to deactivate Galphai/o-GTP proteins, and a G protein regulatory (GPR) motif that binds inactive Galphai1/3-GDP proteins independent of Gbetagamma. GPR interactions with Galphai recruit RGS14 to the plasma membrane to interact with Galphai-linked GPCRs and regulate Galphai signaling. While RGS14 actions on Galpha proteins are well characterized, consequent effects on Gbetagamma signaling remain unknown. Conventional RGS proteins act as dedicated GAPs to deactivate Galpha and Gbetagamma signaling following receptor activation. RGS14 may do the same or, alternatively, may coordinate its actions to deactivate Galpha-GTP with the RGS domain and then capture the same Galpha-GDP via its GPR motif to prevent heterotrimer reassociation and prolong Gbetagamma signaling. To test this idea, we compared the regulation of G protein activation and deactivation kinetics by a conventional RGS protein, RGS4, and RGS14 in response to GPCR agonist/antagonist treatment utilizing bioluminescence resonance energy transfer (BRET). Co expression of either RGS4 or RGS14 inhibited the release of free Gbetagamma after agonist stimulation and increased the deactivation rate of Galpha, consistent with their roles as GTPase activating proteins (GAPs). Overexpression of inactive Galphai1 to recruit RGS14 to the plasma membrane did not alter RGS14's capacity to act as a GAP for a second Galphao protein. These results demonstrate the role of RGS14 as a dedicated GAP and suggest that the G protein regulatory (GPR) motif functions independently of the RGS domain and is silent in regulating GAP activity in a cellular context. PMID- 27713822 TI - Population pharmacokinetic and pharmacodynamic analyses of safinamide in subjects with Parkinson's disease. AB - Safinamide is an orally administered alpha-aminoamide derivative with both dopaminergic and non-dopaminergic properties. Nonlinear mixed effects models for population pharmacokinetic (PK) and pharmacokinetic-pharmacodynamic (PKPD) analyses were developed using records from, respectively, 623 and 668 patients belonging to two Phase 3, randomized, placebo-controlled, double-blind efficacy studies. The aim was to estimate safinamide population PK parameters in patients with Parkinson's disease (PD) on stable levodopa therapy, and to develop a model of safinamide effect on the PD phase of normal functioning (ON-time). The final models were internally evaluated using visual predictive checks (VPCs), prediction corrected-VPC, and nonparametric bootstrap analysis. Safinamide profiles were adequately described by a linear one-compartmental model with first order absorption and elimination. CL/F, Vd/F, and KA (95% confidence interval [CI]) were 4.96 (4.73-5.21) L/h, 166 (158-174) L, and 0.582 (0.335-0.829) h-1, respectively. CL/F and Vd/F increased with body weight, while age, gender, renal function, and exposure to levodopa did not influence safinamide PK. The observed ON-time values were adequately described by a linear model, with time in the study period as dependent variable, and rate of ON-time change and baseline plus offset effect as slope and intercept parameters. Safinamide treatment resulted in an increase in ON-time of 0.73 h (week 4), with further ON-time increase with the same slope as placebo. The increase was not influenced by age, levodopa, or safinamide exposure. The population models adequately describe the population PK of safinamide and safinamide effect on ON-time. No dose adjustments in elderly and mild to moderate renally impaired patients are requested. PMID- 27713819 TI - Attention to emotional stimuli in borderline personality disorder - a review of the influence of dissociation, self-reference, and psychotherapeutic interventions. AB - Interactions between attention and processing of emotional stimuli shed light on both sensitivity to emotional stimuli as well as emotion dysregulation. Both of the latter processes have been proposed as central characteristics of altered emotion processing in those with borderline personality disorder (BPD). This review first summarizes the conflicting behavioural, psychophysiological and neuroimaging evidence for the hypothesis that emotional dysregulation should be reflected by higher distractibility through emotional stimuli in those with BPD. Dissociation, self-reference, as well as symptom severity modulated by psychotherapeutic interventions are proposed to help clarify divergent findings. Data suggest an association of dissociation with impaired task continuation during the presentation of interfering emotional and neutral stimuli, as well as high recruitment of neuronal attention networks together with a blunted emotional response. Considering self-reference, evidence suggests that negative rather than positive information may be more self-relevant to those with BPD. This may be due to a negative self-concept and self-evaluation. Social or trauma-relevant information attracts more attention from individuals with BPD and thus suggests higher self-relevance. After psychotherapeutic interventions, initial evidence may indicate normalization of the way attention and emotional stimuli interact in BPD. When studying attention-emotion interactions in BPD, methodological heterogeneities regarding sample, task, and stimulus characteristics need to be considered. When doing so, dissociation, self-reference, and psychotherapeutic interventions offer promising targets for future studies on attention-emotion interactions in those with BPD. This could promote a deeper insight into the affected individuals' struggle with emotions. PMID- 27713823 TI - Phenotyping and genotyping of CYP2C19 using comparative metabolism of proguanil in sickle-cell disease patients and healthy controls in Nigeria. AB - Polymorphic expression of metabolic enzymes have been identified as one of the key factors responsible for the interindividual/ethnic/racial variability in drug metabolism and effect. In Nigeria, there is a disproportionately high incidence of sickle-cell disease (SCD), a condition characterized by painful crisis frequently triggered by malaria. Proguanil, a substrate of the polymorphic CYP2C19, is a chemoprophylactic antimalarial drug widely used among SCD patients in Nigeria. This study aimed to conduct a comparative CYP2C19 phenotyping among SCD patients and healthy controls and to compare the results with those previously reported. One hundred seventy-seven unrelated subjects comprising 131 SCD patients and 46 non-SCD volunteers were phenotyped. This was carried out by collecting pooled urine samples over 8 h following PG administration. Proguanil and its major CYP2C19-dependent metabolites were measured by high-performance liquid chromatography. Metabolic ratios (MRs) were computed and employed in classifying subjects into poor or extensive metabolizers. Among SCD group, 130 (99.2%) were extensive metabolizers (EMs) and 1 (0.8%) was poor metabolizer (PM) of PG, while 95.7 and 4.3% non-SCDs were EMs and PMs, respectively. MRs ranged from 0.02 to 8.70 for SCD EMs and from 0.22 to 8.33 for non-SCD EMs . Two non SCDs with MRs of 18.18 and 25.76 and the SCD with MR of 16.77 regarded as PMs had earlier been genotyped as CYP2C19*2/*2. Poor metabolizers of proguanil in SCD patients are reported for the first time. Regardless of clinical significance, a difference in metabolic disposition of proguanil and CYP2C19 by SCDs and non-SCDs was established. PMID- 27713825 TI - Frequency and trends of disease-modifying antirheumatic drug (DMARD) use in Germany. AB - The aim of this study was to analyze the population-based frequency of classic (c ) and biologic (b-) disease-modifying antirheumatic drug (DMARD) use over time, selected underlying indications and the specialty of the prescribing physicians in Germany. Based on the claims data of the German Pharmacoepidemiological Research Database (GePaRD), yearly cross-sectional studies were conducted from 2004 to 2011. The prevalence of DMARD use was calculated as the number of persons with at least one dispensation per 1000 persons stratified by sex and age. In 2011, we also obtained the proportion of c- and b-DMARDs users with diagnoses of selected indications and the proportion of dispensations by specialty of the physician. Between 2004 and 2011, the annual prevalence of b-DMARD and c-DMARD use increased from 0.350/00 to 1.540/00 and from 6.530/00 to 8.930/00, respectively. In 2011, the study population comprised 12.8 million insurants with a mean age of 44.0 years. During this year, among c-DMARDs, methotrexate was prescribed most frequently (4.760/00), followed by azathioprine (1.720/00) and sulfasalazine (1.200/00). For b-DMARDs, adalimumab (0.570/00), etanercept (0.460/00), and rituximab (0.230/00) were most frequently used. Notably, b-DMARD users more often had a diagnosis of ankylosing spondylitis and psoriasis compared to c-DMARD-users (20.7% vs. 2.9% and 20.0% vs. 11.4%, respectively) and b-DMARDs were more frequently prescribed by rheumatologists and other specialists. Our population-based study highlights the increasing use of c- and b-DMARDs in Germany. Compared to c-DMARDs, b-DMARDs were commonly used for indications besides rheumatoid arthritis. Future research should therefore also focus on their prescription patterns and safety aspects in indications other than RA. PMID- 27713824 TI - Comparison of [11C]TZ1964B and [18F]MNI659 for PET imaging brain PDE10A in nonhuman primates. AB - Phosphodiesterase 10A (PDE10A) inhibitors show therapeutic effects for diseases with striatal pathology. PET radiotracers have been developed to quantify in vivo PDE10A levels and target engagement for therapeutic interventions. The aim of this study was to compare two potent and selective PDE10A radiotracers, [11C]TZ1964B and [18F]MNI659 in the nonhuman primate (NHP) brain. Double scans in the same cynomolgus monkey on the same day were performed after injection of [11C]TZ1964B and [18F]MNI659. Specific uptake was determined in two ways: nondisplaceable binding potential (BPND) was calculated using cerebellum as the reference region and the PDE-10A enriched striatum as the target region of interest (ROI); the area under the time-activity curve (AUC) for the striatum to cerebellum ratio was also calculated. High-performance liquid chromatography (HPLC) analysis of solvent-extracted NHP plasma identified the percentage of intact tracer versus radiolabeled metabolites samples post injection of each radiotracer. Both radiotracers showed high specific accumulation in NHP striatum. [11C]TZ1964B has higher striatal retention and lower specific striatal uptake than [18F]MNI659. The BPND estimates of [11C]TZ1964B were 3.72 by Logan Reference model (LoganREF) and 4.39 by simplified reference tissue model (SRTM); the BPND estimates for [18F]MNI659 were 5.08 (LoganREF) and 5.33 (SRTM). AUC ratios were 5.87 for [11C]TZ1964B and 7.60 for [18F]MNI659. Based on BPND values in NHP striatum, coefficients of variation were ~10% for [11C]TZ1964B and ~30% for [18F]MNI659. Moreover, the metabolism study showed the percentage of parent compounds were ~70% for [11C]TZ1964B and ~50% for [18F]MNI659 60 min post injection. These data indicate that either [11C]TZ1964B or [18F]MNI659 could serve as suitable PDE10A PET radiotracers with distinguishing features for particular clinical application. PMID- 27713826 TI - Soluble guanylate cyclase redox state under oxidative stress conditions in isolated monkey coronary arteries. AB - Coronary artery disease is associated with oxidative stress due to the excessive generation of free radicals in the vascular wall. This study investigated the impact of tert-butyl hydroperoxide (t-BuOOH), a peroxyl radical generator, on the redox state of soluble guanylate cyclase (sGC) in isolated monkey coronary arteries. Helically cut strips of endothelium-intact monkey coronary arteries treated with the nitric oxide synthase inhibitor NG-nitro-L-arginine (10 MUmol/L) were exposed for approximately 60 min to either no drug or t-BuOOH (100 MUmol/L) in the presence and absence of alpha-tocopherol (300 MUmol/L). Relaxation and cGMP levels in response to the sGC stimulator BAY 41-2272 and the sGC activator BAY 60-2770 were assessed by organ chamber technique and enzyme immunoassay, respectively. The relaxant response to BAY 41-2272 was significantly impaired by the exposure to t-BuOOH, whereas the response to BAY 60-2770 was significantly augmented. In addition, vascular cGMP accumulation caused by BAY 41-2272 was decreased by the exposure to t-BuOOH, whereas for BAY 60-2770, it was increased. These effects of t-BuOOH were abolished by coincubation with alpha-tocopherol. Furthermore, correlations were observed between BAY compound-induced relaxant magnitudes and cGMP levels. Therefore, it is concluded that increased oxidative stress leads to disruption of the sGC redox state in monkey coronary arteries. This finding is of great importance for understanding coronary physiology in primates. PMID- 27713827 TI - Evaluation of a novel PXR-knockout in HepaRGTM cells. AB - The nuclear pregnane X receptor (PXR) regulates the expression of genes involved in the metabolism, hepatobiliary disposition, and toxicity of drugs and endogenous compounds. PXR is a promiscuous nuclear hormone receptor (NHR) with significant ligand and DNA-binding crosstalk with the constitutive androstane receptor (CAR); hence, defining the precise role of PXR in gene regulation is challenging. Here, utilising a novel PXR-knockout (KO) HepaRG cell line, real time PCR analysis was conducted to determine PXR involvement for a range of inducers. The selective PXR agonist rifampicin, a selective CAR activator, 6-(4 chlorophenyl)imidazo[2,1-b][1,3]thiazole-5-carbaldehyde O-(3,4 dichlorobenzyl)oxime (CITCO), and dual activators of CAR and PXR including phenobarbital (PB) were analyzed. HepaRG control cells (5F clone) were responsive to prototypical inducers of CYP2B6 and CYP3A4. No response was observed in the PXR-KO cells treated with rifampicin. Induction of CYP3A4 by PB, artemisinin, and phenytoin was also much reduced in PXR-KO cells, while the response to CITCO was maintained. This finding is in agreement with the abolition of functional PXR expression. The apparent EC50 values for PB were in agreement between the cell lines; however, CITCO was ~threefold (0.3 MUmol/L vs. 1 MUmol/L) lower in the PXR KO cells compared with the 5F cells for CYP2B6 induction. Results presented support the application of the novel PXR-KO cells in the definitive assignment of PXR-mediated CYP2B6 and CYP3A4 induction. Utilization of such cell lines will allow advancement in composing structure activity relationships rather than relying predominantly on pharmacological manipulations and provide in-depth mechanistic evaluation. PMID- 27713828 TI - Efficacy and safety evaluation of claudin-4-targeted antitumor therapy using a human and mouse cross-reactive monoclonal antibody. AB - Claudin-4 (CLDN-4), a tight-junction protein, is overexpressed in various malignant tumors, including gastric, colorectal, pancreatic, and breast cancers. However, CLDN-4 is also expressed in normal tissues, including the liver, pancreas, kidney, and small intestine. Whether CLDN-4 is an effective and safe target for cancer therapy has been unclear owing to the lack of a binder with both CLDN-4 specificity and cross-reactivity to human and murine cells. In this study, we successfully generated a rat anti-CLDN-4 monoclonal antibody (5D12) that was specific to, and cross-reactive with, human and mouse CLDN-4. 5D12 recognized the second extracellular domain of human CLDN-4 in a conformation dependent manner. A human-rat chimeric IgG1 of 5D12 (xi-5D12) activated the Fcgamma IIIa receptor, indicating the activation of antibody-dependent cellular cytotoxicity in CLDN-4-expressing cells. Moreover, xi-5D12 significantly suppressed tumor growth in mice bearing human colorectal and gastric tumors without apparent adverse effects, such as weight loss or liver and kidney damage. These results suggest that CLDN-4 is a potent target for cancer therapy and that an anti-CLDN-4 antibody is a promising candidate anticancer agent. PMID- 27713829 TI - Equine hepatocytes: isolation, cryopreservation, and applications to in vitro drug metabolism studies. AB - Despite reports of the successful isolation of primary equine hepatocytes, there are no published data regarding the successful cryopreservation of these isolated cells. In this study, a detailed description of the procedures for isolation, cryopreservation, and recovery of equine hepatocytes are presented. Furthermore, the intrinsic clearance (Clint) and production of metabolites for three drugs were compared between freshly isolated and recovered cryopreserved hepatocytes. Primary equine hepatocytes were isolated using a two-step collagenase perfusion method, with an average cell yield of 2.47 +/- 2.62 * 106 cells/g of perfused liver tissue and viability of 84.1 +/- 2.62%. These cells were cryopreserved with William's medium E containing 10% fetal bovine serum with 10% DMSO. The viability of recovered cells, after a 30% Percoll gradient, was 77 +/- 11% and estimated recovery rate was approximately 27%. These purified cells were used to determine the in vitro Clint of three drugs used in equine medicine; omeprazole, flunixin, and phenylbutazone, via the substrate depletion method. Cryopreserved suspensions gave a comparable estimation of Clint compared to fresh cells for these three drugs as well as producing the same metabolites. This work paves the way for establishing a bank of cryopreserved equine hepatocytes that can be used for estimating pharmacokinetic parameters such as the hepatic metabolic in vivo clearance of a drug as well as producing horse-specific drug metabolites. PMID- 27713830 TI - Fighting falsified medicines with paperwork - a historic review of Danish legislation governing distribution of medicines. AB - BACKGROUND: Many areas of pharmaceutical legislation in the European Union (EU) are harmonised in order to promote the internal market and protect public health. Ideally, harmonisation leads to less fragmented regulation and cross-border complexities. This study, however, focuses on an increasingly harmonised legislative area that is subject to increases in requirements and complexities: the distribution of medicines. This study compared Danish legislation governing the distribution of medicines before and after Denmark joined the EU in order to assess the impact of EU harmonisation, as well as to evaluate whether the drastic increases in requirements mandated by the Falsified Medicines Directive of 2011 correspond to a new approach to governing the pharmaceutical supply chain. METHODS: A review was conducted of 115 applicable Danish laws, executive orders and guidelines from 1913 to 2014. Legal requirements were organised according to the year they were published and the companies they affected. Greater changes in legislative requirements were developed through inductive content analysis. RESULTS: Early legislation positioned pharmacies as gatekeepers, requiring them to identify and stop medicines of substandard quality. Legislation to regulate the supply chain was slow to materialise. After Denmark joined the EU, the scope of legislation widened to include all actors in the supply chain, and the quantity of legislation increased dramatically. Simultaneously, requirements became more specific, thereby promoting a formalistic interpretation and focusing the attention of companies and authorities on predefined areas with little room to implement innovative solutions. Over time, documentation became the focus of legislation, requiring companies to provide documentary evidence for their compliance with legislation. The Falsified Medicines Directive continues these trends by increasing requirements for documentation and promoting a formalistic interpretation. CONCLUSION: The legislative approach adopted since Denmark joined the EU gives companies and medicine inspectors little room to interpret legislation. The Falsified Medicines Directive does not depart from this approach. Legislation seems more focused on enforcing similar requirements than on benefiting public health. Legislation may benefit from allowing room for local interpretation of requirements. PMID- 27713831 TI - Potential perils of peri-Pokemon perambulation: the dark reality of augmented reality? AB - Recently, the layering of augmented reality information on top of smartphone applications has created unprecedented user engagement and popularity. One augmented reality-based entertainment application, Pokemon Go (Pokemon Company, Tokyo, Japan) has become the most rapidly downloaded in history. This technology holds tremendous promise to promote ambulatory activity. However, there exists the obvious potential for distraction-related morbidity. We report two cases, presenting simultaneously to our trauma center, with injuries sustained secondary to gameplay with this augmented reality-based application. PMID- 27713832 TI - A comparative study of enzyme initiators for crosslinking phenol-functionalized hydrogels for cell encapsulation. AB - BACKGROUND: Dityrosine crosslinking in proteins is a bioinspired method of forming hydrogels. This study compares oxidative enzyme initiators for their relative crosslinking efficiency and cytocompatibility using the same phenol group and the same material platform. Four common enzyme and enzyme-like oxidative initiators were probed for resulting material properties and cell viability post-encapsulation. RESULTS: All four initiators can be used to form phenol-crosslinked hydrogels, however gelation rates are dependent on enzyme type, concentration, and the oxidant. Horseradish peroxidase (HRP) or hematin with hydrogen peroxide led to a more rapid poly (vinyl alcohol)-tyramine (PVA Tyr) polymerization (10-60 min) because a high oxidant concentration was dissolved within the macromer solution at the onset of crosslinking, whereas laccase and tyrosinase require oxygen diffusion to crosslink phenol residues and therefore took longer to gel (2.5+ hours). The use of hydrogen peroxide as an oxidant reduced cell viability immediately post-encapsulation. Laccase- and tyrosinase-mediated encapsulation of cells resulted in higher cell viability immediately post-encapsulation and significantly higher cell proliferation after one week of culture. CONCLUSIONS: Overall this study demonstrates that HRP/H2O2, hematin/H2O2, laccase, and tyrosinase can create injectable, in situ phenol crosslinked hydrogels, however oxidant type and concentration are critical parameters to assess when phenol crosslinking hydrogels for cell-based applications.

AB - BACKGROUND: Depression and post-traumatic stress disorder (PTSD) are significant risks for suicide and other adverse events among US military personnel, but prevalence data among ship-assigned personnel at the onset of deployment are unknown. AIMS: To determine the prevalence of shipboard personnel who screen positive for PTSD and/or major depressive disorder (MDD) at the onset of deployment, and also those who reported these diagnoses made by a physician or healthcare professional in the year prior to deployment. METHOD: Active-duty ship assigned personnel (N = 2078) completed anonymous assessments at the beginning of deployment. Depression was measured using the Center for Epidemiologic Studies Depression Scale (CES-D; score of >=22), and PTSD was assessed using the PTSD Checklist-Civilian Version (PCL-C; both score and symptom criteria were used). RESULTS: In total, 7.3% (n = 151 of 2076) screened positive for PTSD and 22% (n = 461 of 2078) for MDD at deployment onset. Only 6% and 15% of those who screened positive for PTSD or MDD, respectively, had been diagnosed by a healthcare professional in the past year. CONCLUSIONS: Missed opportunities for mental healthcare among screen-positive shipboard personnel reduce the benefits associated with early identification and linkage to care. Improved methods of mental health screening that promote early recognition and referral to care may mitigate psychiatric events in theatre.

PMID- 27713834 TI - Loss of relational continuity of care in schizophrenia: associations with patient satisfaction and quality of care. AB - BACKGROUND: Users of mental health service are concerned about changes in clinicians providing their care, but little is known about their impact. AIMS: To examine associations between changes in staff, and patient satisfaction and quality of care. METHOD: A national cross-sectional survey of 3379 people aged 18 or over treated in secondary care for schizophrenia or schizoaffective disorder. RESULTS: Nearly 41.9% reported at least one change in their key worker during the previous 12 months and 10.5% reported multiple changes. Those reporting multiple changes were less satisfied with their treatment and less likely to report having a care plan, knowing how to obtain help when in a crisis or to have had recommended physical health assessments. CONCLUSIONS: Frequent changes in staff providing care for people with psychosis are associated with poorer quality of care. Greater efforts need to be made to protect relational continuity of care for such patients.

PMID- 27713835 TI - Sequence amplification via cell passaging creates spurious signals of positive adaptation in influenza virus H3N2 hemagglutinin. AB - Clinical influenza A virus isolates are frequently not sequenced directly. Instead, a majority of these isolates (~70% in 2015) are first subjected to passaging for amplification, most commonly in non-human cell culture. Here, we find that this passaging leaves distinct signals of adaptation, which can confound evolutionary analyses of the viral sequences. We find distinct patterns of adaptation to Madin-Darby (MDCK) and monkey cell culture absent from unpassaged hemagglutinin sequences. These patterns also dominate pooled datasets not separated by passaging type, and they increase in proportion to the number of passages performed. By contrast, MDCK-SIAT1 passaged sequences seem mostly (but not entirely) free of passaging adaptations. Contrary to previous studies, we find that using only internal branches of influenza virus phylogenetic trees is insufficient to correct for passaging artifacts. These artifacts can only be safely avoided by excluding passaged sequences entirely from subsequent analysis. We conclude that future influenza virus evolutionary analyses should appropriately control for potentially confounding effects of passaging adaptations. PMID- 27713836 TI - Evolutionary dynamics of Enterococcus faecium reveals complex genomic relationships between isolates with independent emergence of vancomycin resistance. AB - Enterococcus faecium, a major cause of hospital-acquired infections, remains problematic because of its propensity to acquire resistance to vancomycin, which currently is considered first-line therapy. Here, we assess the evolution and resistance acquisition dynamics of E. faecium in a clinical context using a series of 132 bloodstream infection isolates from a single hospital. All isolates, of which 49 (37 %) were vancomycin-resistant, underwent whole-genome sequencing. E. faecium was found to be subject to high rates of recombination with little evidence of sequence importation from outside the local E. faecium population. Apart from disrupting phylogenetic reconstruction, recombination was frequent enough to invalidate MLST typing in the identification of clonal expansion and transmission events, suggesting that, where available, whole-genome sequencing should be used in tracing the epidemiology of E. faecium nosocomial infections and establishing routes of transmission. Several forms of the Tn1549 like element-vanB gene cluster, which was exclusively responsible for vancomycin resistance, appeared and spread within the hospital during the study period. Several transposon gains and losses and instances of in situ evolution were inferred and, although usually chromosomal, the resistance element was also observed on a plasmid background. There was qualitative evidence for clonal expansions of both vancomycin-resistant and vancomycin-susceptible E. faecium with evidence of hospital-specific subclonal expansion. Our data are consistent with continuing evolution of this established hospital pathogen and confirm hospital vancomycin-susceptible and vancomycin-resistant E. faecium patient transmission events, underlining the need for careful consideration before modifying current E. faecium infection control strategies. PMID- 27713838 TI - Two-Dimensional Hermite Filters Simplify the Description of High-Order Statistics of Natural Images. AB - Natural image statistics play a crucial role in shaping biological visual systems, understanding their function and design principles, and designing effective computer-vision algorithms. High-order statistics are critical for conveying local features, but they are challenging to study - largely because their number and variety is large. Here, via the use of two-dimensional Hermite (TDH) functions, we identify a covert symmetry in high-order statistics of natural images that simplifies this task. This emerges from the structure of TDH functions, which are an orthogonal set of functions that are organized into a hierarchy of ranks. Specifically, we find that the shape (skewness and kurtosis) of the distribution of filter coefficients depends only on the projection of the function onto a 1-dimensional subspace specific to each rank. The characterization of natural image statistics provided by TDH filter coefficients reflects both their phase and amplitude structure, and we suggest an intuitive interpretation for the special subspace within each rank. PMID- 27713837 TI - SimBac: simulation of whole bacterial genomes with homologous recombination. AB - Bacteria can exchange genetic material, or acquire genes found in the environment. This process, generally known as bacterial recombination, can have a strong impact on the evolution and phenotype of bacteria, for example causing the spread of antibiotic resistance across clades and species, but can also disrupt phylogenetic and transmission inferences. With the increasing affordability of whole genome sequencing, the need has emerged for an efficient simulator of bacterial evolution to test and compare methods for phylogenetic and population genetic inference, and for simulation-based estimation. We present SimBac, a whole-genome bacterial evolution simulator that is roughly two orders of magnitude faster than previous software and includes a more general model of bacterial evolution, allowing both within- and between-species homologous recombination. Since methods modelling bacterial recombination generally focus on only one of these two modes of recombination, the possibility to simulate both allows for a general and fair benchmarking.

PMID- 27713839 TI - Community Engaged Leadership to Advance Health Equity and Build Healthier Communities. AB - Health is a human right. Equity in health implies that ideally everyone should have a fair opportunity to attain their full health potential and, more pragmatically, that no one should be disadvantaged from achieving this potential. Addressing the multi-faceted health needs of ethnically and culturally diverse individuals in the United States is a complex issue that requires inventive strategies to reduce risk factors and buttress protective factors to promote greater well-being among individuals, families, and communities. With growing diversity concerning various ethnicities and nationalities; and with significant changes in the constellation of multiple of risk factors that can influence health outcomes, it is imperative that we delineate strategic efforts that encourage better access to primary care, focused community-based programs, multi disciplinary clinical and translational research methodologies, and health policy advocacy initiatives that may improve individuals' longevity and quality of life. PMID- 27713840 TI - In silico identification of T-type calcium channel blockers: A ligand-based pharmacophore mapping approach. AB - Limited progress has been made in the quest to identify both selective and non toxic T-type calcium channel blocking compounds. The present research work was directed toward slaking the same by identifying the selective three dimensional (3D) pharmacophore map for T-type calcium channel blockers (CCBs). Using HipHop module in the CATALYST 4.10 software, both selective and non-selective HipHop pharmacophore maps for T-type CCBs were developed to identify its important common pharmacophoric features. HipHop pharmacophore map of the selective T-type CCBs contained six different chemical features, namely ring aromatic (R), positive ionizable (P), two hydrophobic aromatic (Y), hydrophobic aliphatic (Z), hydrogen bond acceptor (H) and hydrogen bond donor (D). However, non-selective T type CCBs contain all the above mentioned features except ring aromatic (R). The present ligand-based pharmacophore mapping approach could thus be utilized in classifying selective vs. non-selective T-type CCBs. Further, the model can be used for virtual screening of several small molecule databases. PMID- 27713841 TI - Late Effects: Focus on Adolescent and Young Adult Cancer Survivors.

PMID- 27713843 TI - Tyrosine Kinase Inhibitors for the Treatment of Chronic-Phase Chronic Myeloid Leukemia: Long-Term Patient Care and Management. AB - Several tyrosine kinase inhibitors (TKIs) are now approved for the treatment of chronic myeloid leukemia in chronic phase. The efficacy of these drugs has been repeatedly demonstrated, as has their tolerability in most patients. However, late and chronic toxicities become an important issue for many patients facing long-term TKI exposure. For patients on long-term imatinib, gastrointestinal events, fluid retention, muscle cramps, fatigue, and hepatotoxicity are among the most common and most clinically relevant adverse events (AEs). A few of these have also emerged as important AEs with some of the newer TKIs. Distinct long term toxicity concerns have emerged for dasatinib (pleural effusion, pulmonary hypertension, headache, and dyspnea) and nilotinib (rash, headache, myalgia, alopecia, and hyperglycemia), whereas due to the recent approval of bosutinib and ponatinib, their long-term toxicity profiles have not been fully characterized. Clinical experience with each of these drugs is accumulating, and ensuring proper adherence and monitoring for potential AEs is essential for effective treatment.

AB - BACKGROUND: Ischemic stroke following anterior cervical diskectomy and fusion (ACDF) is an exceedingly rare complication. There are only three previous cases focusing on this problem in the literature; here, we present the fourth case. CASE DESCRIPTION: A patient, cared for at an outside institution, developed a delayed ischemic stroke 3 days following an ACDF. This complication was attributed to carotid manipulation precipitating vascular injury in the setting of multiple comorbid vascular and coagulopathic risk factors, including previously undiagnosed carotid atherosclerosis, a prior history of pulmonary embolus requiring Warfarin anticoagulation (held perioperatively), acute dehydration, and atrial fibrillation. CONCLUSIONS: This case demonstrates the importance of focused history and examination in appropriate patients prior to ACDF, with special consideration given to the significance of age, comorbidities including coagulopathy and arrhythmia, and potential underlying vascular disease as markers for increased risk of perioperative thrombotic stroke associated with carotid manipulation. Patients at higher risk warrant comprehensive preoperative assessment, including medical evaluation, carotid imaging, and consideration for alternative surgical approaches. PMID- 27713853 TI - Dual diagnostic catheter technique in the endovascular management of anterior communicating artery complex aneurysms. AB - BACKGROUND: The configuration of the anterior communicating artery (AcomA) complex is important in the endovascular treatment of AcomA complex aneurysms. In cases of codominant anterior cerebral arteries (ACA), coil embolization may result in inadvertent occlusion of the contralateral ACA due to poor visualization. A second diagnostic catheter in the contralateral carotid artery may help with visualization of this angiographic blind spot. To our knowledge, the safety and efficacy of this dual diagnostic catheter technique have never been assessed. METHODS: A cohort of consecutive patients that underwent coil embolization of an AcomA complex aneurysm at a major academic institution in the United States between 2007 and 2014 were retrospectively reviewed. RESULTS: Eighty-two patients who had an AcomA complex aneurysm treated with coil embolization were identified. The dual diagnostic catheter technique was used in 17 (20.7%) patients. Aneurysms treated with the dual diagnostic catheter technique were less frequently ruptured and had less favorable dome-to-neck ratios as well as neck width for primary coil embolization. The rate of codominant ACAs was significantly higher and stent-assisted coil embolization was performed more frequently. The rate of thromboembolic complications, angiographic outcome, and retreatment did not differ between both the groups. CONCLUSIONS: The dual diagnostic catheter technique is a safe and effective method during coil embolization of AcomA complex aneurysms and preferred for aneurysms with codominant ACAs, incorporation of either A1 or A2 segments into the aneurysm, and aneurysms with a wide neck and low dome-to-neck ratios. PMID- 27713854 TI - Contralateral interlaminar approach for intraforaminal lumbar degenerative disease with special emphasis on L5-S1 level: A technical note. AB - BACKGROUND: Intraforaminal disc herniations at the L5-S1 level are extremely surgically challenging lesions. Intracanal approaches frequently require partial or total facetectomy, which may lead to instability. Solely extraforaminal approaches may offer limited visualization of the more medial superiorly exiting and inferiorly exiting nerve roots; this approach is also more complicated at L5 S1 due to the often large L5 transverse process and the iliac wing. METHODS: Nine patients with intraforaminal L5-S1 disc herniations, foraminal stenosis, or synovial cysts underwent contralateral interlaminar approaches for lesion resection. Preoperative and postoperative visual analog scale scores were evaluated, and complications were reviewed. RESULTS: All 9 patients demonstrated immediate postoperative clinical improvement. None of the patients exhibited complications and none developed instability or neuropathic disorders. CONCLUSIONS: Although the number of cases in our sample was very small (9 in total), the contralateral interlaminar approach appeared to effectively address multiple degenerative L5-S1 foraminal pathologies. Large studies are needed to further evaluate the pros and cons of this approach.

PMID- 27713857 TI - On Being in the Wrong Place: The Role of Children's Conceptual Understanding and Ballgame Experience when Judging a Football Player's Offside Position. AB - We investigated the role of children's conceptual understanding and ballgame experience when judging whether a football player is in an offside position, or not. In the offside position, a player takes advantage of being behind the defence line of the opposing team and just waits for the ball to arrive in order to score a goal. We explained the offside rule to 7- and 9-year-old children with a Subbuteo setup. They produced drawings of an offside position until it was correct (drawing to criterion). Thereafter, children judged whether a designated player was in an offside position in a computerized task. Like adults, also children found it easier to judge when a player was in a wrong rather than a right place. Only when including frequency of ballgame practice in the analysis it was revealed that boys were better independently of age as they judged the offside position more systematically. PMID- 27713855 TI - Orthostatic Tremor: An Update on a Rare Entity. AB - BACKGROUND: Orthostatic tremor (OT) remains among the most intriguing and poorly understood of movement disorders. Compared to Parkinson's disease or even essential tremor, there are very few articles addressing more basic science issues. In this review, we will discuss the findings of main case series on OT, including data on etiology, pathophysiology, diagnostic approach, treatment strategies, and outcome. METHODS: Data for this review were identified by searching PUBMED (January 1966 to August 2016) for the terms "orthostatic tremor" or "shaky leg syndrome," which yielded 219 entries. We did not exclude papers on the basis of language, country, or publication date. The electronic database searches were supplemented by articles in the authors' files that pertained to this topic. RESULTS: Owing to its rarity, the current understanding of OT is limited and is mostly based on small case series or case reports. Despite this, a growing body of evidence indicates that OT might be a progressive condition that is clinically heterogeneous (primary vs. secondary cases) with a broader spectrum of clinical features, mainly cerebellar signs, and possible cognitive impairment and personality disturbances. Along with this, advanced neuroimaging techniques are now demonstrating distinct anatomical and functional changes, some of which are consistent with neuronal loss. DISCUSSION: OT might be a family of diseases, unified by the presence of leg tremor, but further characterized by etiological and clinical heterogeneity. More work is needed to understand the pathogenesis of this condition. PMID- 27713858 TI - Ascending colon cancer associated with deposited ova of Schistosoma japonicum in non-endemic area. AB - Some reports suggest the positive correlation between Schistosoma japonicum infection and colorectal cancer, however the sufficient evidence that supports a causal relationship between them has not been established. Japan used be an endemic area of S. japonicum infection for 40 years ago. But now all of Japan is a non-endemic area of S. japonicum infection. We report a case of ascending colon cancer associated with deposited ova of S. japonicum in non-endemic area. PMID- 27713859 TI - Chronic Q fever: A missed prosthetic valve endocarditis possibly for years. AB - Chronic Coxiella burnetii endocarditis usually develops in people with underlying heart disease and accounts for 60-70% of chronic Q fever. Onset is generally insidious and manifestations are atypical. The authors report a case of Coxiella burnetii prosthetic valve endocarditis in a 53 years- old patient with recurrent mechanical valve dehiscence on mitral position. He lived in a rural area with sheep and goats on the surroundings. During a 9 year- period, he was submitted to three cardiac mitral valve surgeries two of which with no Q fever diagnosis suspicion. Diagnosis was based on a positive serology test (Indirect imunofluorescence). Treatment consisted in a combination of prolonged course of hydroxychloroquine plus doxycycline and surgical replacement of the mitral valve, with a favorable outcome. With this case report, the authors pretend to highlight the not always expected diagnosis of Q fever endocarditis. If not considered, Coxiella burnetii endocarditis may lead to multiple cardiac surgeries, greater morbidity and potentially death.

AB - We report a histologically pure stage 1 seminoma with an elevated human chorionic gonadotropin (hCG). A 38 year-old man was referred for the evaluation of the left testicular swelling. He showed an elevated serum hCG level of 25,265 mIU/ml with normal a fetoprotein and lactate dehydrogenase. Imaging showed heterogeneous tumor without any metastatic lesions. We conducted 4 courses of chemotherapy before detecting hCG nadir. The final pathological report showed pure seminoma with syncytiotrophoblastic cells but no choriocarcinoma components. The patient remains disease free until present time. The case raised several questions regarding diagnosis and treatment strategy for bulky testicular seminoma. PMID- 27713863 TI - Potential Impact on Clinical Decision Making via a Genome-Wide Expression Profiling: A Case Report. AB - Management of men with prostate cancer is fraught with uncertainty as physicians and patients balance efficacy with potential toxicity and diminished quality of life. Utilization of genomics as a prognostic biomarker has improved the informed decision-making process by enabling more rationale treatment choices. Recently investigations have begun to determine whether genomic information from tumor transcriptome data can be used to impact clinical decision-making beyond prognosis. Here we discuss the potential of genomics to alter management of a patient who presented with high-risk prostate adenocarcinoma. We suggest that this information help selecting patients for advanced imaging, chemotherapies, or clinical trial. PMID- 27713864 TI - Non-Radiographic Risk Factors Differentiating Atypical Lipomatous Tumors from Lipomas. AB - PURPOSE: To determine non-radiographic risk factors differentiating atypical lipomatous tumors (ALTs) from lipomas. METHODS: All patients with deep-seated lipomatous tumors of the extremities treated from January 2000 to October 2010 were retrospectively reviewed. Factors reviewed included age, gender, tumor location, size, histology, local recurrence, dedifferentiation, and metastasis. Multivariate logistic regression models were used to evaluate the effects of patient characteristics on ALT status. RESULTS: Ninety-four lipomas and 46 ALTs were included. Patients with an ALT were older (median: 60.5 vs. 55 years). Lipomas were evenly distributed between upper (48.9%) and lower extremities (51.1%), whereas ALTs predominately involved the lower extremities (91.3%). Median ALT size (22 cm) was greater than lipomas (10 cm), p < 0.0001. One lipoma (1.04%) recurred at 77 months and five ALTs (10.9%) recurred at an average of 39 months (19-64 months). Two ALTs originally treated with wide resection recurred with a dedifferentiated component and were treated with wide re-excision and chemotherapy. No metastases or tumor-related deaths occurred in either group at the time of last follow-up. Patients older than 60 years, tumors greater than 10 cm, or thigh location, were more likely to be diagnosed with an ALT (p < 0.05). CONCLUSION: Lipomatous tumors were more likely to be ALTs when the tumor was at least 10 cm in size, located in the thigh, or found in patients that were 60 years of age or older. These risk factors may be used to guide management and surveillance strategies, when lipomatous tumors do not display characteristic radiographic features. PMID- 27713865 TI - Characterization of the Adherence of Clostridium difficile Spores: The Integrity of the Outermost Layer Affects Adherence Properties of Spores of the Epidemic Strain R20291 to Components of the Intestinal Mucosa. AB - Clostridium difficile is the causative agent of the most frequently reported nosocomial diarrhea worldwide. The high incidence of recurrent infection is the main clinical challenge of C. difficile infections (CDI). Formation of C. difficile spores of the epidemic strain R20291 has been shown to be essential for recurrent infection and transmission of the disease in a mouse model. However, the underlying mechanisms of how these spores persist in the colonic environment remains unclear. In this work, we characterized the adherence properties of epidemic R20291 spores to components of the intestinal mucosa, and we assessed the role of the exosporium integrity in the adherence properties by using cdeC mutant spores with a defective exosporium layer. Our results showed that spores and vegetative cells of the epidemic R20291 strain adhered at high levels to monolayers of Caco-2 cells and mucin. Transmission electron micrographs of Caco-2 cells demonstrated that the hair-like projections on the surface of R20291 spores are in close proximity with the plasma membrane and microvilli of undifferentiated and differentiated monolayers of Caco-2 cells. Competitive binding assay in differentiated Caco-2 cells suggests that spore-adherence is mediated by specific binding sites. By using spores of a cdeC mutant we demonstrated that the integrity of the exosporium layer determines the affinity of adherence of C. difficile spores to Caco-2 cells and mucin. Binding of fibronectin and vitronectin to the spore surface was concentration-dependent, and depending on the concentration, spore-adherence to Caco-2 cells was enhanced. In the presence of an aberrantly-assembled exosporium (cdeC spores), binding of fibronectin, but not vitronectin, was increased. Notably, independent of the exosporium integrity, only a fraction of the spores had fibronectin and vitronectin molecules binding to their surface. Collectively, these results demonstrate that the integrity of the exosporium layer of strain R20291 contributes to selective spore adherence to components of the intestinal mucosa. PMID- 27713868 TI - The Effect of the Family Empowerment Model on Quality of Life in Children with Chronic Renal Failure: Children's and Parents' Views. AB - BACKGROUND: Chronic renal failure (CRF) causes a gradual decline in kidney function to the extent that CRF patients need long-term clinical care, which affects the patients' family function and quality of life (QoL). OBJECTIVES: The present study was conducted to study the effects of the family-centered empowerment model on QoL in children with CRF during 2012-2013. PATIENTS AND METHODS: In this quasi-experimental study, 68 children with CRF and their parents were randomly assigned to two groups, intervention and control, via a random numbers table. An empowerment program was then conducted over the course of seven 45-minute sessions, and a questionnaire to ascertain demographic characteristics and the core pediatric QoL Inventory (version 4) were administered to both groups before the sessions and one month after the last training session. The data were analyzed using SPSS 20. RESULTS: The mean age of the children was 10.2 and 10.5 years in the intervention and control groups, respectively. The duration of the disease was five years in both groups. Furthermore, a significant difference was seen in the mean score of the children's QoL from their own perspectives in the physical and psychosocial domains and the total QoL score in the intervention group before and after the training (P < 0.05). CONCLUSIONS: Since family centered empowerment interventions can determine the training- and treatment related needs of patients and are low cost and effective, they may help parents promote their children's self-efficacy and QoL. PMID- 27713866 TI - Hijacking Host Cell Highways: Manipulation of the Host Actin Cytoskeleton by Obligate Intracellular Bacterial Pathogens. AB - Intracellular bacterial pathogens replicate within eukaryotic cells and display unique adaptations that support key infection events including invasion, replication, immune evasion, and dissemination. From invasion to dissemination, all stages of the intracellular bacterial life cycle share the same three dimensional cytosolic space containing the host cytoskeleton. For successful infection and replication, many pathogens hijack the cytoskeleton using effector proteins introduced into the host cytosol by specialized secretion systems. A subset of effectors contains eukaryotic-like motifs that mimic host proteins to exploit signaling and modify specific cytoskeletal components such as actin and microtubules. Cytoskeletal rearrangement promotes numerous events that are beneficial to the pathogen, including internalization of bacteria, structural support for bacteria-containing vacuoles, altered vesicular trafficking, actin dependent bacterial movement, and pathogen dissemination. This review highlights a diverse group of obligate intracellular bacterial pathogens that manipulate the host cytoskeleton to thrive within eukaryotic cells and discusses underlying molecular mechanisms that promote these dynamic host-pathogen interactions. PMID- 27713869 TI - Short-Period Influence of Chronic Morphine Exposure on Serum Levels of Sexual Hormones and Spermatogenesis in Rats. AB - BACKGROUND: Increased rates of addiction and its broad societal complications are well known. One of the most important systems that may malfunction in drug abusers is the reproductive system, and evaluating patients for this potential risk may lead to increased awareness. MATERIALS AND METHODS: Thirty 60-day-old male rats were divided into control and target groups. The target group underwent 5 mg/kg intraperitoneal injections of morphine twice a day while the control group underwent normal saline injections (at the same dosage). After 60 days, the rats were anesthetized, and after blood sampling, they underwent bilateral orchiepididymectomy. Histological and hormonal evaluations were performed on the samples. RESULTS: Levels of sex hormonal features and spermatogenesis were significantly reduced in the target group compared to the control group. LH levels showed a meaningful decrease in the target group, but FSH and testosterone levels did not. On histological section analysis, mature sperm were meaningfully decreased in the target group. CONCLUSIONS: Chronic use of opioids may lead to alterations in sexual features and sexual hormones. Therefore, opioids have the potential to cause infertility. These changes may result from the effect of the drugs on the hypophysis or hypothalamus, the direct effect of the drugs on the seminiferous tubules, or a combination of both. The findings suggest that public awareness about addiction may cause decreased infertility rates. PMID- 27713867 TI - Anaplasma phagocytophilum APH0032 Is Exposed on the Cytosolic Face of the Pathogen-Occupied Vacuole and Co-opts Host Cell SUMOylation. AB - Anaplasma phagocytophilum, a member of the family Anaplasmataceae and the obligate intracellular bacterium that causes granulocytic anaplasmosis, resides in a host cell-derived vacuole. Bacterial proteins that localize to the A. phagocytophilum-occupied vacuole membrane (AVM) are critical host-pathogen interfaces. Of the few bacterial AVM proteins that have been identified, the domains responsible for AVM localization and the host cell pathways that they co opt are poorly defined. APH0032 is an effector that is expressed and localizes to the AVM late during the infection cycle. Herein, the APH0032 domain that is essential for associating with host cell membranes was mapped. Immunofluorescent labeling of infected cells that had been differentially permeabilized confirmed that APH0032 is exposed on the AVM's cytosolic face, signifying its potential to interface with host cell processes. SUMOylation is the covalent attachment of a member of the small ubiquitin-like modifier (SUMO) family of proteins to lysines in target substrates. Previous work from our laboratory determined that SUMOylation is important for A. phagocytophilum survival and that SUMOylated proteins decorate the AVM. Algorithmic prediction analyses identified APH0032 as a candidate for SUMOylation. Endogenous APH0032 was precipitated from infected cells using a SUMO affinity matrix, confirming that the effector co-opts SUMOylation during infection. APH0032 pronouncedly colocalized with SUMO1, but not SUMO2/3 moieties on the AVM. Ectopic expression of APH0032 in A. phagocytophilum infected host cells significantly boosted the bacterial load. This study delineates the first domain of any Anaplasmataceae protein that is essential for associating with the pathogen-occupied vacuole membrane, demonstrates the importance of APH0032 to infection, and identifies it as the second A. phagocytophilum effector that co-opts SUMOylation, thus underscoring the relevance of this post-translational modification to infection. PMID- 27713870 TI - Comparison of Hemoglobin Levels Before and After Hemodialysis and Their Effects on Erythropoietin Dosing and Cost. AB - BACKGROUND: Hemoglobin levels measured after hemodialysis, as compared to hemoglobin levels measured before hemodialysis, are suggested to be a more accurate reflection of the hemoglobin levels between hemodialysis sessions, and to be a better reference point for adjusting erythropoietin dosing. OBJECTIVES: The aim of this study was to compare the hemoglobin levels before and after hemodialysis, to calculate the required erythropoietin doses based on these levels, and to develop a model to predict effective erythropoietin dosing. PATIENTS AND METHODS: In this cross-sectional study, the hemoglobin levels of 52 patients with end-stage renal disease were measured before and after hemodialysis. The required erythropoietin doses and the differences in cost were calculated based on the hemoglobin levels before and after hemodialysis. A model to predict the adjusted erythropoietin dosages based on post-hemodialysis hemoglobin levels was proposed. RESULTS: Hemoglobin levels measured after hemodialysis were significantly higher than the hemoglobin levels before hemodialysis (11.1 +/- 1.1 vs. 11.9 +/- 1.2 g/dL, P < 0.001, 7% increase). The mean required erythropoietin dose based on post-hemodialysis hemoglobin levels was significantly lower than the corresponding erythropoietin dose based on pre hemodialysis hemoglobin levels (10947 +/- 6820 vs. 12047 +/- 7542 U/week, P < 0.001, 9% decrease). The cost of erythropoietin was also significantly lower when post-hemodialysis levels were used (15.96 +/- 9.85 vs. 17.57 +/- 11.00 dollars/patient/week, P < 0.001). This translated into 83.72 dollars/patient/year in cost reduction. The developed model for predicting the required dosage is: Erythropoietin (U/week) = 43540.8 + (-2734.8) * Post-hemodialysis Hb* (g/dL). [(R2) = 0.221; *P < 0.001]. CONCLUSIONS: Using post-hemodialysis hemoglobin levels as a reference point for erythropoietin dosing can result in significant dose and cost reduction, and can protect hemodialysis patients from hemoconcentration. The prediction of the erythropoietin adjusted dosage based on post-hemodialysis Hb may also help in avoiding overdosage. PMID- 27713871 TI - Sequence-identification of Candida species isolated from candidemia. AB - BACKGROUND: Candida species are the most prevalent cause of invasive fungal infections such as candidemia. Candidemia is a lethal fungal infection among immunocompromised patients worldwide. Main pathogen is Candida albicans but a global shift in epidemiology toward non-albicans species have reported. Species identification is imperative for good management of candidemia as a fatal infection. The aim of the study is to identify Candida spp. obtained from candidemia and determination of mortality rate among this population. MATERIALS AND METHODS: The study was performed during February 2014 to March 2015 in Tehran, Iran. Two-hundred and four blood cultures were evaluated for fungal bloodstream infection. Identification of isolates was carried out using phenotypic tests and polymerase chain reaction sequencing technique. RESULTS: Twenty-two out of 204 patients (10.8%) had candidemia. Candida parapsilosis was the most prevalent species (45.4%), followed by C. albicans (31.8%) and Candida glabrata (22.7%). Male to female sex ratio was 8/14. CONCLUSIONS: The emergence of resistant strains of Candida species should be considered by physicians to decrease the mortality of this fatal fungal infection by appropriate treatment. PMID- 27713872 TI - Prevalence of occult hepatitis B virus infection in hemodialysis patients in Isfahan, Iran. AB - BACKGROUND: The absence of a detectable hepatitis B surface antigen (HBsAg) with or without hepatitis B core antibody (anti-HBc) or hepatitis B surface antibody (anti-HBs) in the presence of hepatitis B virus-DNA (HBV-DNA) is defined as occult HBV infection. This study was aimed to evaluate the prevalence of occult HBV infection in patients receiving hemodialysis (HD) in Isfahan, Iran. MATERIALS AND METHODS: This cross sectional study was done on 400 patients without acute or chronic HBV infection with end-stage renal disease undergoing regular HD. Blood samples were collected prior to the HD session, and serological markers of viral hepatitis B included HBsAg, anti-HBs and anti-HBc were measured using standard third generation commercially available enzyme immunoassays kit, then samples of positive anti-HBc and negative anti-HBs were tested for HBV DNA using quantitative real-time polymerase chain reaction techniques. Data were analyzed by SPSS using t-test and Chi-square test. RESULTS: The mean age of patients was 51.6 +/- 11.2 years. Anti-HBc positive was observed in 32 (8%) of 400 studied patients with negative HBsAg. Of 32 patients with anti-HBc positive, 15 were males and 17 were females with mean age of 49.7 +/- 12.6 years. Among 32 patients with anti-HBc positive, 10 patients were negative for anti-HBs. All of 10 patients were negative for HBV DNA. The prevalence of occult HBV infection was 0%. CONCLUSIONS: The prevalence of occult HBV infection in HBsAg negative patients undergoing HD was 0% and look to be among the lowest worldwide. So, occult HBV infection is not a significant health problem in HD patients in this region. PMID- 27713873 TI - Computed tomography-guided percutaneous core needle biopsy for diagnosis of mediastinal mass lesions: Experience with 110 cases in two university hospitals in Isfahan, Iran. AB - BACKGROUND: Computed tomography-guided percutaneous core needle biopsy (PCNB) is a diagnostic technique for initial assessment of mediastinal mass lesions. This study was conducted to evaluate its diagnostic yield and its complication rate. MATERIALS AND METHODS: We reviewed the records of CT-guided PCNB in 110 patients with mediastinal mass lesions performed in Kashani and Alzahra Hospitals, Isfahan, from 2006 to 2012. Gender, age at biopsy, size, and anatomic location of the lesion, number of passes, site of approach, complications, and final diagnosis were extracted. RESULTS: Our series encompasses 52 (47.2%) females and 58 (52/7%) males with mean age of 41 +/- 8 years. The most common site of involvement was the anterior mediastinum (91.8% of cases). An average of 3/5 passes per patient has been taken for tissue sampling. Parasternal site was the most frequent approach taken for PCNB (in 78.1% of cases). Diagnostic tissue was obtained in 99 (90%) biopsies while, in 11 (10%) cases, specimen materials were inadequate. Lymphoma (49.5%) and bronchogenic carcinoma (33.3%) were the most frequent lesions in our series. The overall complication rate was 17.2% from which 10.9% was pneumothorax, 5.4% was hemoptysis, and 0.9% was vasovagal reflex. CONCLUSION: CT-guided PCNB is a safe and reliable procedure that can provide a precise diagnosis for patients with both benign and malignant mediastinal masses, and it is considered the preferred first diagnostic procedure use for this purpose. PMID- 27713874 TI - The difference in correlation between insulin resistance index and chronic inflammation in type 2 diabetes with and without metabolic syndrome. AB - BACKGROUND: Insulin resistance (IR) is associated with low-grade systemic inflammation. It plays an important role in the pathogenesis of type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) in patients with metabolic syndrome (MetS). It is unclear whether diabetic patients with MetS confer elevated CVD risk and outcomes beyond the impact of individual's components of MetS. The aim of this study is to highlight the central role of IR, inflammation, triglyceride/high-density lipoprotein- cholesterol (TG/HDL-C) ratio, and atherogenic index of plasma (AIP) in T2DM with MetS. MATERIALS AND METHODS: This cross-sectional study comprised 130 men distributed into three groups, namely Controls: 40 nondiabetic healthy volunteers; Group I: 40 T2DM patients without MetS, and Group II: 50 T2DM patients with MetS. Fasting blood samples were collected for the measurement of blood lipid profile, glucose, insulin, hemoglobin A1c, and high-sensitivity C-reactive protein (hs-CRP). TG/HDL-C ratio, AIP, and homeostasis model assessment of insulin resistance (HOMA-IR) were calculated. RESULTS: Significant positive association was observed between HOMA IR and hs-CRP only in Group II and between HOMA-IR and TG/HDL-C ratio in all subjects. Significant differences were seen in waist and hip circumferences, waist/hip ratio, body mass index, systolic blood pressure, fasting blood glucose, TGs, HDL-C, insulin, hs-CRP, HOMA-IR, TG/HDL ratio, and AIP between Controls and Group I with Group II. CONCLUSIONS: In T2DM with MetS, coexistence of elevated atherogenic indices, systemic inflammation, and association between HOMA-IR and TG/HDL-C ratio were seen. These factors are considered having important role in elevated CVD risk beyond MetS components in these patients. PMID- 27713875 TI - Symmetrical peripheral gangrene: Unusual complication of dengue fever. AB - Symmetrical peripheral gangrene (SPG) is a rare clinical entity, infective, and noninfective both types of etiologies are responsible. The basic underlying pathology in SPG is being disseminated intravascular coagulation and carries a high mortality. Here, we describe a 52-year-old male with dengue fever, who developed bilateral symmetrical dry gangrene of both hand and feet. His dengue IgM antibody was positive. All the peripheral pulses of the affected limbs were palpable. Color Doppler study of upper and lower limb vessels showed normal flow. The patient was managed with intravenous fluids, low molecular weight heparin, and fresh frozen plasma. His general condition was improved within 72 h with no further progression of gangrene. Clinician should suspect the possibility of SPG while dealing a case of dengue fever presenting as peripheral gangrene. PMID- 27713876 TI - The relationship between macro- and micro-nutrients intake and risk of preterm premature rupture of membranes in pregnant women of Isfahan. AB - BACKGROUND: Since preterm premature rupture of membranes (PPROM) is one of the most important complications of pregnancy and its relationship with nutrition status have not been surveyed comprehensively, we decided to study the relationship of maternal received nutrients (36 macro- and micro-nutrients) in three trimesters and PPROM which could be considered as a unique study. MATERIALS AND METHODS: In this prospective cohort study, data was collected by filling a questionnaire through interviews with 620 pregnant women who had no parameters to affect pregnancy outcome. 48-hr dietary recalls were completed for eligible women at 11th-15th, 26th, 34th-37th weeks of gestation. Physical activity was also assessed using a standard questionnaire. Also pregnant mother's reproductive and demographic characteristic and supplementation are considered. RESULTS: The mean value of received saturated fatty acids, polyunsaturated fatty acids and energy, in the first trimester (P < 0.001, P = 0.007, and P < 0.001 respectively), the mean values of calcium, sodium intake in the second trimester (P = 0.045, P = 0.006, and P = 0.004 respectively), Vitamins C, A (mg), beta-carotene, cartenoids intake in the second trimester (P = 0.03, P = 0.001, P = 0.007, and P = 0.01 respectively), and higher Vitamin C intake during the first trimester (P = 0.02) was significantly greater among subjects with PPROM compared to the others. CONCLUSIONS: The mean value of mentioned received nutrients in subjects who experienced PPROM later in pregnancy was higher than the others, which is independent of demographic and reproductive characteristic, estimated physical activity, and supplementation. Therefore, these findings could be considered in the nutritional programming for pregnant women to manage the risk of PPROM. PMID- 27713877 TI - The Spectrum of Congenital Heart Disease with Transposition of the Great Arteries from the Cardiac Registry of the University of Padua. AB - Transposition of the great arteries (TGA) is a cardiac condition in which the arterial trunks arise from the inappropriate ventricle: the aorta from the right ventricle and the pulmonary trunk from the left ventricle [discordant ventriculo arterial (VA) connection]. In complete TGA, the discordant VA connection is associated with situs solitus or inversus and concordant atrioventricular (AV) connection. The hemodynamic consequence of these combined connections is that systemic and pulmonary circulations function in "parallel" rather than in "series". The presence of situs solitus or inversus associated with both AV and VA discordant connections characterizes a different anatomical complex known as "corrected TGA." In these hearts, the double discordance at AV and VA levels permits a normal sequence of the blood flow from the right atrium to the pulmonary artery and from the left atrium to the aorta. The systemic and pulmonary circulation in these hearts functions regularly in series, and the blood sequence is "physiologically corrected." Thus, the term transposition, either complete or corrected, identifies two precise, different anatomical complexes, both characterized by VA discordance. However, among congenital heart disease (CHD), there are other anatomical complexes with discordant VA connection in the setting of isomeric atrial situs (right or left) or of univentricular AV connections (double inlet or absent connections). In these latter conditions, the term "transposition" is still necessary to stress that the great arteries are "transposed" in relation to the ventricular septum (aorta from the right ventricle and pulmonary trunk from the left ventricle) but certainly does not figure out the anatomical complexes named complete or corrected transposition. We reviewed the hearts with discordant VA connection of our Anatomical Collection, consisting of 1,640 specimens with CHD, with the aim to discuss the anatomy and the frequency of the anatomical variants of TGA and to clarify terminology and classification. The knowledge of the precise anatomy of these malformation are really important for clinical diagnosis and surgical planning.

PMID- 27713878 TI - ERK5 and Cell Proliferation: Nuclear Localization Is What Matters. AB - ERK5, the last MAP kinase family member discovered, is activated by the upstream kinase MEK5 in response to growth factors and stress stimulation. MEK5-ERK5 pathway has been associated to different cellular processes, playing a crucial role in cell proliferation in normal and cancer cells by mechanisms that are both dependent and independent of its kinase activity. Thus, nuclear ERK5 activates transcription factors by either direct phosphorylation or acting as co-activator thanks to a unique transcriptional activation TAD domain located at its C terminal tail. Consequently, ERK5 has been proposed as an interesting target to tackle different cancers, and either inhibitors of ERK5 activity or silencing the protein have shown antiproliferative activity in cancer cells and to block tumor growth in animal models. Here, we review the different mechanisms involved in ERK5 nuclear translocation and their consequences. Inactive ERK5 resides in the cytosol, forming a complex with Hsp90-Cdc37 superchaperone. In a canonical mechanism, MEK5-dependent activation results in ERK5 C-terminal autophosphorylation, Hsp90 dissociation, and nuclear translocation. This mechanism integrates signals such as growth factors and stresses that activate the MEK5-ERK5 pathway. Importantly, two other mechanisms, MEK5-independent, have been recently described. These mechanisms allow nuclear shuttling of kinase inactive forms of ERK5. Although lacking kinase activity, these forms activate transcription by interacting with transcription factors through the TAD domain. Both mechanisms also require Hsp90 dissociation previous to nuclear translocation. One mechanism involves phosphorylation of the C-terminal tail of ERK5 by kinases that are activated during mitosis, such as Cyclin-dependent kinase-1. The second mechanism involves overexpression of chaperone Cdc37, an oncogene that is overexpressed in cancers such as prostate adenocarcinoma, where it collaborates with ERK5 to promote cell proliferation. Although some ERK5 kinase inhibitors have shown antiproliferative activity it is likely that those tumors expressing kinase-inactive nuclear ERK5 will not respond to these inhibitors. PMID- 27713880 TI - An Algorithm Measuring Donor Cell-Free DNA in Plasma of Cellular and Solid Organ Transplant Recipients That Does Not Require Donor or Recipient Genotyping. AB - Cell-free DNA (cfDNA) has significant potential in the diagnosis and monitoring of clinical conditions. However, accurately and easily distinguishing the relative proportion of DNA molecules in a mixture derived from two different sources (i.e., donor and recipient tissues after transplantation) is challenging. In human cellular transplantation, there is currently no useable method to detect in vivo engraftment, and blood-based non-invasive tests for allograft rejection in solid organ transplantation are either non-specific or absent. Elevated levels of donor cfDNA have been shown to correlate with solid organ rejection, but complex methodology limits implementation of this promising biomarker. We describe a cost-effective method to quantify donor cfDNA in recipient plasma using a panel of high-frequency single nucleotide polymorphisms, next-generation (semiconductor) sequencing, and a novel mixture model algorithm. In vitro, our method accurately and rapidly determined donor:recipient DNA admixture. For in vivo testing, donor cfDNA was serially quantified in an infant with a urea cycle disorder after receiving six daily infusions of donor liver cells. Donor cfDNA isolated from 1 to 2 ml of recipient plasma was detected as late as 24 weeks after infusion suggesting engraftment. The percentage of circulating donor cfDNA was also assessed in pediatric and adult heart transplant recipients undergoing routine endomyocardial biopsy with levels observed to be stable over time and generally measuring <1% in cases without moderate or severe cellular rejection. Unlike existing non-invasive methods used to define the proportion of donor cfDNA in solid organ transplant patients, our assay does not require sex mismatch, donor genotyping, or whole-genome sequencing and potentially has broad application to detect cellular engraftment or allograft injury after transplantation. PMID- 27713881 TI - A Comparative Assessment of the Risks of Introduction and Spread of Foot-and Mouth Disease among Different Pig Sectors in Australia. AB - Small-scale pig producers are believed to pose higher biosecurity risks for the introduction and spread of exotic diseases than commercial pig producers. However, the magnitude of these risks is poorly understood. This study is a comparative assessment of the risk of introduction and spread of foot-and-mouth disease (FMD) through different sectors of the pig industry: (1) large-scale pig producers; (2) small-scale producers (<100 sows) selling at saleyards and abattoirs; and (3) small-scale producers selling through informal means. An exposure and consequence assessments were conducted using the World Organization for Animal Health methodology for risk analysis, assuming FMD virus was introduced into Australia through illegal importation of infected meat. A quantitative assessment, using scenario trees and Monte Carlo stochastic simulation, was used to calculate the probabilities of exposure and spread. Input data for these assessments were obtained from a series of data gathering exercises among pig producers, industry statistics, and literature. Findings of this study suggest there is an Extremely low probability of exposure (8.69 * 10-6 to 3.81 * 10-5) for the three sectors of the pig industry, with exposure through direct swill feeding being 10-100 times more likely to occur than through contact with infected feral pigs. Spread of FMD from the index farm is most likely to occur through movement of contaminated fomites, pigs, and ruminants. The virus is more likely to spread from small-scale piggeries selling at saleyards and abattoirs than from other piggeries. The most influential factors on the spread of FMD from the index farm is the ability of the farmer to detect FMD, the probability of FMD spread through contaminated fomites and the presence of ruminants on the farm. Although small-scale producers selling informally move animals less frequently and do not use external staff, movement of pigs to non commercial pathways could jeopardize animal traceability in the event of a disease outbreak. This study suggests that producers' awareness on and engagement with legislative and industry requirements in relation to biosecurity and emergency animal disease management needs to be improved. Results from this study could be used by decision-makers to prioritize resource allocation for improving animal biosecurity in the pig industry. PMID- 27713882 TI - Current epidemiology of sepsis in mainland China. AB - The disease burden of sepsis is a global issue. Most of the large-scale epidemiological investigations on sepsis have been carried out in developed countries. The population of 1.3 billion in mainland China accounts for approximately 1/5th of the whole world population. Thus, the knowledge of the incidence and mortality of sepsis in mainland China is vital before employing measures for its improvement. However, most of the epidemiological data of sepsis in mainland China was obtained from ICU settings, and thus lacks the population based incidence and mortality of sepsis. In the present review, we summarized the limited literature encompassing the incidence, mortality, long-term outcome, and pathogens of sepsis in mainland China. Therefore, it might provide some valuable information regarding the sepsis disease burden and current issues in the management of sepsis in mainland China. PMID- 27713883 TI - Epidemiologic trends of sepsis in western countries. AB - Since the American College of Chest Physicians (ACCP) and the Society of Critical care Medicine (SCCM) published the first consensus definition of syndromes related to sepsis in 1992, the knowledge of epidemiology of sepsis has clearly improved, although no prospective studies have been performed to analyse the incidence of sepsis in general population. There are differences in epidemiologic trends in sepsis between western countries and low-income and middle-income countries. In the United States (US), most of epidemiologic studies have been based on large, administrative databases, reporting an increase in the incidence of severe sepsis over years. In general, studies describing epidemiology of sepsis outside the US use clinical definitions and intensive care unit (ICU) observational cohort designs instead of administrative databases and definitions. Incidence of sepsis has increased over years, probably due to progressive aging of population, the existence of more comorbidities and maybe the liberal use of sepsis codification, by including patients with less severity. Notwithstanding, mortality due to sepsis is clearly decreasing over years, probably to improvement in ICU care, although absolute mortality is growing on account of the raise in incidence. Risk factors for sepsis are the two ends of life, male sex, US black race, presence of comorbidities and certain genetic variants. Respiratory tract infections are the most common source of sepsis, and, nowadays, Gram-positive infections are more frequent that Gram-negative sepsis in most prospective studies. PMID- 27713885 TI - The immunocompromised oncohematological critically ill patient: considerations in severe infections. AB - Sepsis and septic shock remain a major cause of mortality among critically ill patient. This is particularly relevant among cancer patients as highlighted by different series showing that up to one in five patients admitted to intensive care units (ICU) with sepsis have cancer, and also, sepsis is a leading reason for ICU admission in patients with cancer. The classic predictors of mortality among these patients (such as cancer lineage, neutropenia degree, or bone marrow transplantation history) have changed during the last decades, and they should no longer be used to rule out ICU admission. Instead, a newer approach to these patients should be performed taking into account organ failure assessment and prior performance status. When a doubt exists about the criteria for ICU admission, not only a trial of ICU management should be proposed to assert that no patients are withhold of the opportunity for recovering from the acute condition, but also an early admission, to prevent more derangement, and thus impact on mortality. PMID- 27713884 TI - Resistance mechanisms. AB - By definition, the terms sepsis and septic shock refer to a potentially fatal infectious state in which the early administration of an effective antibiotic is the most significant determinant of the outcome. Because of the global spread of resistant bacteria, the efficacy of antibiotics has been severely compromised. S. pneumonia, Escherichia coli (E. coli), Klebsiella, Acinetobacter, and Pseudomonas are the predominant pathogens of sepsis and septic shock. It is common for E. coli, Klebsiella, Acinetobacter and Pseudomonas to be resistant to multiple drugs. Multiple drug resistance is caused by the interplay of multiple resistance mechanisms those emerge via the acquisition of extraneous resistance determinants or spontaneous mutations. Extended-spectrum beta-lactamases (ESBLs), carbapenemases, aminoglycoside-modifying enzymes (AMEs) and quinolone resistance determinants are typically external and disseminate on mobile genetic elements, while porin-efflux mechanisms are activated by spontaneous modifications of inherited structures. Porin and efflux mechanisms are frequent companions of multiple drug resistance in Acinetobacter and P. aeruginosa, but only occasionally detected among E. coli and Klebsiella. Antibiotic resistance became a global health threat. This review examines the major resistance mechanisms of the leading microorganisms of sepsis. PMID- 27713887 TI - New role of biomarkers: mid-regional pro-adrenomedullin, the biomarker of organ failure. AB - Mid-regional pro-adrenomedullin (MR-proADM) has a good biomarker profile: its half-life is several hours, and its plasma concentrations can be determined in clinical practice, it is essentially irrelevant, but proportionally represents the levels and activity of adrenomedullin (ADM). ADM synthesis is widely distributed in tissues, including bone, adrenal cortex, kidney, lung, blood vessels and heart. Its fundamental biological effects include vasodilator, positive inotropic, diuretic, natriuretic and bronchodilator. It has been described high levels in septic patients, interacting directly with the relaxation of vascular tone, triggering hypotension of these patients. It is also found high levels in other diseases such as hypertension, heart failure, respiratory failure, renal failure, cirrhosis and cancer. MR-proADM has been identified as a prognostic marker, stratifying the mortality risk in patients with sepsis in emergency department (ED) and ICU. Evolutionary MR-proADM levels and clearance marker to the 2nd-5th days of admission help to determine the poor performance and the risk of mortality in patients with severe sepsis admitted to the ICU. The MR-proADM levels are more effective than procalcitonin (PCT) and C reactive protein (CRP) levels to determine an unfavorable outcome and the risk of mortality in patients with sepsis admitted to the ICU. It has also proved useful in patients diagnosed with organ dysfunction of infectious etiology. MR-proADM levels are independent of the germ conversely it is related to the magnitude of organ failure and therefore severity. We consider advisable incorporating the MR proADM the panel of biomarkers necessary for the diagnosis and treatment of critically ill patients admitted to the ICU with severe sepsis. The combined PCT and MR-proADM levels could represent a valid tool in the clinical practice to timely identify patients with bacterial infections and guide the diagnosis and treatment of sepsis and septic shock. PMID- 27713886 TI - The role of genetics and antibodies in sepsis. AB - During the course of sepsis when immunosuppression predominates, the concentrations of circulating immunoglobulins (IGs) are decreased and this is associated with adverse outcomes. The production of IGs as response to invasive bacterial pathogens takes place through a complex pathway starting from the recognition of the antigen (Ag) by innate immune cells that process and present Ags to T cells. The orchestration of T-helper (Th) lymphocyte responses directs specific B cells and ends with the production of IGs by plasma cells. All molecules implicated in this process are encoded by genes bearing single nucleotide polymorphisms (SNPs). Meta-analysis of case-control studies have shown that the carriage of minor frequency SNPs of CD14, TLR2 and TNF is associated with increased sepsis risk. The ambiguity of results of clinical trials studying the clinical efficacy of exogenous IG administration in sepsis suggests that efficacy of treatment should be considered after adjustment for SNPs of all implicated genes in the pathway of IG production. PMID- 27713888 TI - Current understanding in source control management in septic shock patients: a review. AB - Sepsis and septic shock is one of the leading causes of death worldwide. Antibiotics, fluid resuscitation support of vital organ function and source control are the cornerstones for the treatment of these patients. Source control measures include all those actions taken in the process of care to control the foci of infection and to restore optimal function of the site of infection. Source control represents the multidisciplinary team required in order to optimize critical care for septic shock patients. In the last decade an increase interest on fluids, vasopressors, antibiotics, and organ support techniques in all aspects whether time, dose and type of any of those have been described. However information of source control measures involving minimal invasion and new techniques, time of action and outcome without it, is scarce. In this review the authors resumes new information, recommendations and future directions on this matter when facing the more common types of infections. PMID- 27713889 TI - Right first time! AB - Septic shock is still a lethal disease in intensive care units (ICU). The mortality can exceed 40% even with therapeutic management. The high mortality is clearly associated with the delay of appropriate antimicrobial therapy. Early diagnosis and identification of infectious source is the mainstay of optimal therapeutic management. On the other hand, source control and optimize antibiotic dosing according to pharmacokinetics (PK)/pharmacodynamics (PD) properties of antibiotics and organ dysfunction of patients are required to get the best clinical outcome. PMID- 27713890 TI - Implementing sepsis bundles. AB - Sepsis bundles represent key elements of care regarding the diagnosis and treatment of patients with septic shock and allow ones to convert complex guidelines into meaningful changes in behavior. Sepsis bundles endorsed the early goal-directed therapy (EGDT) and their implementation resulted in an improved outcome of septic shock patients. They induced more consistent and timely application of evidence-based care and reduced practice variability. These benefits mainly depend on the compliance with sepsis bundles, highlighting the importance of dedicated performance improvement initiatives, such as multifaceted educational programs. Nevertheless, the interest of early goal directed therapy in septic shock patients compared to usual care has recently been questioned, leading to an update of sepsis bundles in 2015. These new sepsis bundles may also exhibit, as the previous bundles, some limits and pitfalls and the effects of their implementation still needs to be evaluated. PMID- 27713893 TI - Design and Psychometric Properties of Male Adolescent Health Needs-Assessment Scale. AB - BACKGROUND: Given the importance of adolescents' health in establishing health in the newly thriving generation of every society, the first step for adolescents' health promotion is health needs assessment. The present study was, therefore, conducted to design a valid and reliable scale for health needs assessment of male adolescents. METHODS: This is an exploratory sequential mixed method study (2014-2015). The qualitative part was performed using content analysis approach and aimed to generate items pool. Data collection was performed by 7 focus group discussions with 51 male adolescents, and 10 semi-structured in-depth interviews with 10 other adolescents. Nine further in-depth interviews were also performed with 9 key informants. Purposive sampling was used and continued until data saturation. In the quantitative part, the designed scale was psychometrically assessed through the examination of the face and content validities using qualitative and quantitative methods and also the construct validity using the exploratory factor analysis along with the tool's internal consistency and stability. RESULTS: The content analysis of the data from the qualitative part led to the extraction of 4 main themes and 103 items, which moved to the quantitative stage. The mean content validity index of the scale was estimated 0.91 and content validity ratio was 0.89. The exploratory factor analysis showed 4 factors for the designed scale (49 items), including physical, psychological, social and sexual health needs. The internal consistency and the stability assessment of the scale showed 0.79 and 0.89, respectively. (P<0.001). CONCLUSION: According to the psychometric assessment, MAHNAS is a valid and reliable scale compatible with the Iranian culture that can be used in the health needs assessment of male adolescents. PMID- 27713892 TI - Effects of a Lifestyle Modification Program on Knowledge, Attitude and Practice of Hypertensive Patients with Angioplasty: A Randomized Controlled Clinical Trial. AB - BACKGROUND: Lack of knowledge, attitude and practice are some of the barriers of having a healthy lifestyle and controlling high blood pressure. This study aimed to determine the effectiveness of a lifestyle modification program on knowledge, attitude and practice of hypertensive patients with angioplasty. METHODS: This study was a randomized controlled clinical trial conducted from November to April 2014 on 60 hypertensive patients with angioplasty in Shahid Chamran hospital of Isfahan, Iran. The samples were randomly assigned to two equal groups. Data collection was performed in three stages by a researcher-made questionnaire. The intervention plan was 6 education sessions and then follow up were done by phone call. The gathered data were analyzed via SPSS (V.20), using t-test, Chi-square, repeated measurement, and post hoc LSD test and ANOVA statistics. RESULTS: The mean score of knowledge, attitude and practice in the experimental group immediately after the intervention was 77.8+/-7.2, 88.3+/-6.4 and 86.2+/-6.5, respectively and one month after the intervention was 80.8+/-7.4, 91.1+/-3.5 and 92.5+/-2.2, respectively. But in the control group, the mean score of knowledge, attitude and practice immediately after the intervention (34.90+/-11.23, 61.11+/ 6.28, and 38.64+/-7.15) and one month after the intervention was (38.64+/-7.15, 59.56+/-6.31 and 37.27+/-7.26. CONCLUSION: Lifestyle modification program can be effective in promoting the knowledge, attitude and practice of hypertensive patients with angioplasty. Nurses can use this program in their care provision programs for these patients. Trial Registration Number:IRCT2015062420912N3. PMID- 27713891 TI - Vasoactive agents for the treatment of sepsis. AB - The article describes some commonly used vasoactive agents in patients with septic shock. Depending on their distinct pharmacological properties, their effects on vascular bed and cardiac function are different. For example, dopamine has equivalent effect on heart and vasculature, which can result in increases in cardiac output, mean arterial pressure and heart rate. Dobutamine is considered as inodilator because it has potent effect on cardiac systole and vasculature. Patients with sepsis and septic shock sometimes have coexisting cardiac dysfunction that justifies the use of dobutamine. Levosimendan is a relatively new agent exerting its inodilator effect by increasing sensitivity of myocardium to calcium. Some preliminary studies showed a promising result of levosimendan on reducing mortality. PMID- 27713894 TI - Pain Experience in Hemophilia Patients: A Hermeneutic Phenomenological Study. AB - BACKGROUND: Pain, as a crucial subsequence of joint hemorrhages in hemophilia patients, is chronic, debilitating, and distracting. This study aimed to describe and interpret pain experiences of hemophilia patients in their lives. METHODS: This qualitative study with hermeneutic phenomenological approach was conducted on fourteen hemophilia patients who had been referred to a hemophilia center affiliated to Shiraz University of Medical Sciences, Shiraz, Iran. The study question was "what is the meaning of pain in hemophilia patients' lives? The data were collected through semi-structured interviews and field notes through purposeful sampling. Then, thematic analysis with van Manen's six-step methodological framework was used. MAX.QDA qualitative software package, 2010, was used to analyze the data. RESULTS: The three main themes that emerged in this study were "alteration in physical health", "engagement in psychological problems", and "impairment in social relationships". Alteration in physical health consisted of three subthemes, namely "impairment of physical function", "change in body physics", and "disturbance in sleep quality". In addition, two subthemes including "nostalgia of pain in adults with hemophilia" and "psychological distress" emerged from engagement in psychological problems. Finally, "loss of social activity" and "change in relationships" were related to impairment in social relationships. CONCLUSION: The present study highlighted alteration in physical health, engagement in psychological problems, and impairment in social relationship as a result of pain in hemophilia patients. Thus, healthcare providers and family members have to pay special attention to these problems. Besides, providing complementary therapy interventions is suggested for reducing these issues. PMID- 27713895 TI - Effectiveness of Cognitive Behavioral Therapy on the Quality of Sleep in Women with Multiple Sclerosis: A Randomized Controlled Trial Study. AB - BACKGROUND: Multiple sclerosis is accompanied by secondary clinical signs such as insomnia. Considering the side effects of drugs and also increasing acceptability of psychotherapy methods in health systems, we aimed to determine the effect of group cognitive behavioral therapy on the quality of sleep in women with multiple sclerosis in 2014. METHODS: This study is a randomized controlled clinical conducted on 72 women with multiple sclerosis who referred to medical centers of Isfahan. After convenience sampling, participants were randomly allocated into two equal groups of control (n=36) and intervention (n=36). In the intervention group, cognitive behavioral therapy was performed in 8 sessions. The control group, along with receiving the common drugs, participated in 3 group sessions and talked about their feelings and experiences. Data were gathered using Pittsburgh Sleep Quality Index (PSQI) and analyzed through independent t-test, Chi-square, Mann Whitney, ANOVA with repeated measure, using SPSS 18. RESULTS: There was a significant difference between the mean score of sleep quality of the control and intervention groups immediately and one month after the intervention (P<0.001). ANOVA with repeated measure test showed that the mean score of sleep quality of patients in the intervention group had a significant difference at three stages of before, immediately and one month after the intervention. CONCLUSIONS: According to the results of this study, cognitive behavioral therapy, as an effective and cost-effective therapy, could improve sleep quality in patients with multiple sclerosis.

AB - BACKGROUND: Self-care needs are major problems among stroke patients. Nurses can support them through interventions such as education, a change in their attitude and emphasis on their remaining abilities. However, research has shown some weak points in the quality of care given to these patients. So the aim of this study was to improve the nurses' practice in self-care education to stroke patients. METHODS: The findings of evaluation phase showed that during action research, approaching the nurses' empowerment in self-care education to stroke patients has been set in motion. The nursing practice improvement, knowledge based practice, nurses' attitude change, ability to respond against routinization, and motivation promotion emphasize the success of change process. Facilitators and barriers of educating patients are acknowledged by the participants as a factor influencing the continuation of change. RESULTS: The lack of nurses' educating performance skills was overcome using action research and changes were made to improve the performance of nurses. CONCLUSIONS: The lack of nurses' educating performance skills was overcome using action research and changes were made to improve the performance of nurses. PMID- 27713897 TI - Psychological Empowerment Model in Iranian Pregnant Women. AB - BACKGROUND: Women's empowerment programs during pregnancy focus primarily on increasing women's health goals and psychological empowerment has been considered important in most issues related to pregnant mothers' mental health. Using path analysis, this study aims to examine the direct and indirect components of psychological empowerment of pregnant mothers. METHODS: This model-testing study was conducted in Gorgan, northwest of Iran during three months in spring of 2015. Through random cluster sampling, a total number of 160 pregnant women were selected from 10 urban medical centers and clinics as primary centers. We used Spritzer's Psychological empowerment scale. Suitable sampling based on Nunally and Bernstein was followed in the model. The relationships between the dependent variables were then examined by means of path analysis using Amos 18. RESULTS: The psychological empowerment of pregnant mothers (PEPW) model is impacted by individual factors, such as marriage age and employment, including some subjectively rated factors such as marital satisfaction and experience of violence. The PEPW model was deemed appropriate as optimum conditions indicators of goodness of fit; low index of chi2/df shows little difference between the conceptual model and observed data, while RMSEA value indicated the goodness of fit. Other indicators such as CMIN=0.957, CMIN/DF=0.957, P-CLOSE=0.418, chi2=0.957 and probability level=0.328 the fact that the model is ideal. The mothers' employment had the highest coefficient in the PEPW path model .731 (0.443, 0.965) bootstrap confidence intervals by 95%, and with a p-value of less than 0.05. CONCLUSIONS: The mothers' employment is the most important factor in psychological empowerment, but it cannot be addressed quickly. Programming to increase marital satisfaction followed by a decrease in family violence and prevention of early marriage are necessary for promotion of psychological empowerment during pregnancy. PMID- 27713899 TI - Relationship between Gender Roles and Sexual Assertiveness in Married Women. AB - BACKGROUND: Evidence indicates that sexual assertiveness is one of the important factors affecting sexual satisfaction. According to some studies, traditional gender norms conflict with women's capability in expressing sexual desires. This study examined the relationship between gender roles and sexual assertiveness in married women in Mashhad, Iran. METHODS: This cross-sectional study was conducted on 120 women who referred to Mashhad health centers through convenient sampling in 2014-15. Data were collected using Bem Sex Role Inventory (BSRI) and Hulbert index of sexual assertiveness. Data were analyzed using SPSS 16 by Pearson and Spearman's correlation tests and linear Regression Analysis. RESULTS: The mean scores of sexual assertiveness was 54.93+/-13.20. According to the findings, there was non-significant correlation between Femininity and masculinity score with sexual assertiveness (P=0.069 and P=0.080 respectively). Linear regression analysis indicated that among the predictor variables, only Sexual function satisfaction was identified as the sexual assertiveness summary predictor variables (P=0.001). CONCLUSION: Based on the results, sexual assertiveness in married women does not comply with gender role, but it is related to Sexual function satisfaction. So, counseling psychologists need to consider this variable when designing intervention programs for modifying sexual assertiveness and find other variables that affect sexual assertiveness. PMID- 27713898 TI - Factors Influencing School Health in Elementary Schools in Isfahan, Iran: A Qualitative Study. AB - BACKGROUND: Students' health and future health of the community are related to providing health care in schools and since in every society, different contextual factors affect this matter, the present study aims to recognize the factors influencing the health care elementary students are provided with. METHODS: This qualitative content analysis was performed in 2014 in Isfahan. This study was conducted on school health instructors of elementary schools. Through targeted sampling, 15 health care providers, two mothers and 3 principals from 23 elementary schools were selected. Twenty-two semi-structured interviews were performed. Qualitative data analysis was done using qualitative content analysis. RESULTS: In this study, 3 concepts were extracted: family umbrella over health (with two sub-categories of 'family's social status and its effect on health' and 'family and health'), functional resources (with two sub-categories of 'opportunity', 'availability of resources for diagnosis') and health components (with two sub-categories of 'culture', 'the value of school health'). These contextual factors must be considered in providing health care for schools. CONCLUSIONS: Consideration of effective contextual factors on providing elementary students with health care can help improve health for this group. PMID- 27713900 TI - The Burden of Care: Mothers' Experiences of Children with Congenital Heart Disease. AB - BACKGROUND: Mothers play a key role in caring for their sick children. Their experiences of care were influenced by culture, rules, and the system of health and care services. There are few studies on maternal care of children with congenital heart disease. Also, each of them has studied a particular aspect of care. The present research aimed to understand care experiences of mothers of children with congenital heart disease. METHODS: A conventional content analysis was used to obtain rich data. The goal of content analysis is "to provide knowledge and deeper understanding of the phenomenon under the study". The study was conducted in Kerman, Iran in 2014, on mothers of children with CHD. The purposive sampling technique was used to select the participants. Participants were 14 mothers of children with CHD and one father and one nurse of open heart surgery unit, from two hospitals affiliated with Kerman University of Medical Sciences. Eighteen semi-structured interviews were constructed. Data were analyzed using conventional content analysis. MAXQDA 2007 software (VERBI GmbH, Berlin, Germany) was used to classify and manage the coding. Constant comparative method was done for data analysis. The reliability and validity of the findings, including the credibility, confirm ability, dependability, and transferability, were assessed. RESULTS: According to the content analysis, the main theme was the catastrophic burden of child care on mothers that included three categories: 1) the tension resulting from the disease, 2) involvement with internal thoughts, and 3) difficulties of care process. CONCLUSION: The results of this study may help health care professionals to provide supportive and educational packages to the patients, mothers and Family members until improving the management of patient's care. PMID- 27713901 TI - Resilience and Its Contributing Factors in Adolescents in Long-Term Residential Care Facilities Affiliated to Tehran Welfare Organization. AB - BACKGROUND: Resilience is a quality that affects an individual's ability to cope with tension. The present study was conducted to determine resilience and its contributing factors in high-risk adolescents living in residential care facilities affiliated to Tehran Welfare Organization in order to help develop effective preventive measures for them. METHODS: The present descriptive study was conducted on 223 adolescents living in 15 different governmental residential care centers in 2014. Participants were selected through convenience sampling. The data required were collected via the Wagnild and Young Resilience Scale with content validity (S-CVI=0.92) and a reliability of alpha=0.77 and r=0.83 (P<0.001). The data obtained were analyzed in SPSS-20 using descriptive and inferential statistics including Chi-square test, independent t-test and ANOVA. RESULTS: The adolescents' mean score of resilience was 84.41+/-11.01. The level of resilience was moderate in 46.2% of the participants and was significantly higher in the female than in the male adolescents (P=0.006); moreover, the score obtained was lower in primary school children as compared to middle school and high school students (P<0.001). CONCLUSION: Directors of care facilities and residential care personnel should adopt preventive resilience-based strategies in order to optimize resilience among adolescents, particularly the male. It is important to provide a basis to prevent adolescents' academic failure and place a stronger value on education than the past.

PMID- 27713903 TI - Assessing Academic Self-Efficacy, Knowledge, and Attitudes in Undergraduate Physiology Students. AB - Academic self-efficacy affects the success of students in the sciences. Our goals were to develop an instrument to assess the self-efficacy and attitudes toward science of students in an undergraduate physiology course. We hypothesized 1) that our instrument would demonstrate that students taking this course would exhibit greater self-efficacy and more positive attitudes toward science than students in a non-science undergraduate course, and 2) that the physiology students' self-efficacy and attitudes would improve after completing the course. A 25-question survey instrument was developed with items investigating demographic information, self-efficacy, content knowledge, confidence, and attitudes regarding science. Students in either an undergraduate physiology course (Group P) or a history course (Group H) completed the survey. Forty-eight students in Group P completed both PRE- and POST-class surveys, while 50 students in Group H completed the pre-class survey. The academic self-efficacy of Group P as assessed by the PRE-survey was significantly higher than Group H (p=0.0003). Interestingly, there was no significant difference between groups in content knowledge in the PRE-survey. The self-efficacy of Group P was significantly higher as assessed by the POST-survey, when compared to the PRE-survey (p<0.0001) coincident with an improvement (p<0.001) in content knowledge for Group P in the POST-survey. This study established a survey instrument with utility in assessing self-efficacy, attitudes, and content knowledge. Our approach has applicability to studies designed to determine the impact of instructional variables on academic self-efficacy, attitudes, and confidence of students in the sciences. PMID- 27713904 TI - A Synthesis of Current Surveillance Planning Methods for the Sequential Monitoring of Drug and Vaccine Adverse Effects Using Electronic Health Care Data. AB - INTRODUCTION: The large-scale assembly of electronic health care data combined with the use of sequential monitoring has made proactive postmarket drug- and vaccine-safety surveillance possible. Although sequential designs have been used extensively in randomized trials, less attention has been given to methods for applying them in observational electronic health care database settings. EXISTING METHODS: We review current sequential-surveillance planning methods from randomized trials, and the Vaccine Safety Datalink (VSD) and Mini-Sentinel Pilot projects-two national observational electronic health care database safety monitoring programs. FUTURE SURVEILLANCE PLANNING: Based on this examination, we suggest three steps for future surveillance planning in health care databases: (1) prespecify the sequential design and analysis plan, using available feasibility data to reduce assumptions and minimize later changes to initial plans; (2) assess existing drug or vaccine uptake, to determine if there is adequate information to proceed with surveillance, before conducting more resource-intensive planning; and (3) statistically evaluate and clearly communicate the sequential design with all those designing and interpreting the safety-surveillance results prior to implementation. Plans should also be flexible enough to accommodate dynamic and often unpredictable changes to the database information made by the health plans for administrative purposes. CONCLUSIONS: This paper is intended to encourage dialogue about establishing a more systematic, scalable, and transparent sequential design-planning process for medical-product safety-surveillance systems utilizing observational electronic health care databases. Creating such a framework could yield improvements over existing practices, such as designs with increased power to assess serious adverse events. PMID- 27713906 TI - The role of substance use motives in the associations between minority stressors and substance use problems among young men who have sex with men. AB - Young men who have sex with men (YMSM) report higher rates of substance use than their heterosexual peers and minority stress has been posited as a risk factor for substance use. The associations between specific types of minority stress and substance use have been inconsistent throughout the literature and few studies have examined mechanisms underlying these associations. Drawing on minority stress theory and the motivational model of alcohol use, we propose that one mechanism underlying these associations may be people's motivations for using substances, including using substances to cope with negative emotions and to enhance pleasure. The goals of the current study were: (1) to examine the associations among minority stressors, substance use motives, and substance use problems; and (2) to examine substance use motives as mediators of the associations between minority stressors and substance use problems. Baseline self report data were used from a cohort of 370 YMSM enrolled in a larger study of substance use and sexual behavior. Results indicated that using marijuana to cope mediated the association between victimization and marijuana use problems. Using other drugs to cope mediated the associations between victimization and drug use problems and between internalized stigma and drug use problems. Drinking to cope and to enhance pleasure mediated the association between internalized stigma and alcohol use problems. In sum, substance use motives, especially using substances to cope, act as mechanisms through which certain types of minority stress influence substance use problems among YMSM. PMID- 27713907 TI - Utility of electronic medical record for recruitment in clinical research: from rare to common disease. AB - BACKGROUND: Recruitment for clinical trials is a major challenge. Movement disorders, which do not have associated diagnostic laboratory tests, may be especially prone to inaccuracy in coding. Our objective was to evaluate the accuracy of diagnostic codes such as cervical dystonia (CD) and PD in an electronic medical record. METHODS: Retrospective chart review was performed to confirm the ICD-9 diagnoses of PD, CD and diabetes mellitus type 2 (DM-2), using published clinical diagnostic criteria (PD, CD) and hemoglobin A1c >= 6.5 (DM-2). RESULTS: 421 charts (n=129, n=142, n=150 for PD, CD and DM-2, respectively) were reviewed. The accuracy rate was different between all diseases examined with an overall p<0.001. In post hoc pairwise comparisons, the accuracy of DM-2 diagnosis by ICD-9 (96.6%) was greater than CD (88.0%) and both greater than PD (55.0%) (p<=0.003). CONCLUSIONS: Using an electronic medical record based screening of clinically diagnosed diseases such as CD may be more accurate than previously thought and may identify potential clinical trial participants even without confirmatory lab tests available. PMID- 27713905 TI - A Harmonized Data Quality Assessment Terminology and Framework for the Secondary Use of Electronic Health Record Data. AB - OBJECTIVE: Harmonized data quality (DQ) assessment terms, methods, and reporting practices can establish a common understanding of the strengths and limitations of electronic health record (EHR) data for operational analytics, quality improvement, and research. Existing published DQ terms were harmonized to a comprehensive unified terminology with definitions and examples and organized into a conceptual framework to support a common approach to defining whether EHR data is 'fit' for specific uses. MATERIALS AND METHODS: DQ publications, informatics and analytics experts, managers of established DQ programs, and operational manuals from several mature EHR-based research networks were reviewed to identify potential DQ terms and categories. Two face-to-face stakeholder meetings were used to vet an initial set of DQ terms and definitions that were grouped into an overall conceptual framework. Feedback received from data producers and users was used to construct a draft set of harmonized DQ terms and categories. Multiple rounds of iterative refinement resulted in a set of terms and organizing framework consisting of DQ categories, subcategories, terms, definitions, and examples. The harmonized terminology and logical framework's inclusiveness was evaluated against ten published DQ terminologies. RESULTS: Existing DQ terms were harmonized and organized into a framework by defining three DQ categories: (1) Conformance (2) Completeness and (3) Plausibility and two DQ assessment contexts: (1) Verification and (2) Validation. Conformance and Plausibility categories were further divided into subcategories. Each category and subcategory was defined with respect to whether the data may be verified with organizational data, or validated against an accepted gold standard, depending on proposed context and uses. The coverage of the harmonized DQ terminology was validated by successfully aligning to multiple published DQ terminologies. DISCUSSION: Existing DQ concepts, community input, and expert review informed the development of a distinct set of terms, organized into categories and subcategories. The resulting DQ terms successfully encompassed a wide range of disparate DQ terminologies. Operational definitions were developed to provide guidance for implementing DQ assessment procedures. The resulting structure is an inclusive DQ framework for standardizing DQ assessment and reporting. While our analysis focused on the DQ issues often found in EHR data, the new terminology may be applicable to a wide range of electronic health data such as administrative, research, and patient-reported data. CONCLUSION: A consistent, common DQ terminology, organized into a logical framework, is an initial step in enabling data owners and users, patients, and policy makers to evaluate and communicate data quality findings in a well-defined manner with a shared vocabulary. Future work will leverage the framework and terminology to develop reusable data quality assessment and reporting methods. PMID- 27713908 TI - PPM1D/WIP1 in medulloblastoma. PMID- 27713910 TI - The anti-cancer components of Ganoderma lucidum possesses cardiovascular protective effect by regulating circular RNA expression. AB - To examine the role of oral Ganoderma spore oil in cardiovascular disease, we used transverse aortic constriction (TAC) in mice to model pressure overload induced cardiomyopathy. Our preliminary results demonstrated a potential cardioprotective role for spore oil extracted from Ganoderma. We found that Ganoderma treatment normalized ejection fraction and corrected the fractional shortening generated by TAC. We also found evidence of reduced left ventricular hypertrophy as assessed by left ventricular end diastolic diameter. Analysis of total RNA expression using cardiac tissue samples from these mice corroborated our findings. We found reduced expression of genes associated with heart failure, including a novel circular RNA circ-Foxo3. Thus our data provides evidence for Ganoderma lucidum as a potential cardioprotective agent, warranting further preclinical exploration. PMID- 27713909 TI - Selective glucocorticoid receptor-activating adjuvant therapy in cancer treatments. AB - Although adverse effects and glucocorticoid resistance cripple their chronic use, glucocorticoids form the mainstay therapy for acute and chronic inflammatory disorders, and play an important role in treatment protocols of both lymphoid malignancies and as adjuvant to stimulate therapy tolerability in various solid tumors. Glucocorticoid binding to their designate glucocorticoid receptor (GR), sets off a plethora of cell-specific events including therapeutically desirable effects, such as cell death, as well as undesirable effects, including chemotherapy resistance, systemic side effects and glucocorticoid resistance. In this context, selective GR agonists and modulators (SEGRAMs) with a more restricted GR activity profile have been developed, holding promise for further clinical development in anti-inflammatory and potentially in cancer therapies. Thus far, the research into the prospective benefits of selective GR modulators in cancer therapy limped behind. Our review discusses how selective GR agonists and modulators could improve the therapy regimens for lymphoid malignancies, prostate or breast cancer. We summarize our current knowledge and look forward to where the field should move to in the future. Altogether, our review clarifies novel therapeutic perspectives in cancer modulation via selective GR targeting. PMID- 27713911 TI - Weaponizing human EGF-containing fibulin-like extracellular matrix protein 1 (EFEMP1) for 21st century cancer therapeutics. AB - De-regulated EFEMP1 gene expression in solid tumors has been widely reported with conflicting roles. We dissected EFEMP1 to identify domains responsible for its cell context-dependent dual functions, with the goal being to construct an EFEMP1 derived tumor-suppressor protein (ETSP) that lacked tumor-promoting function. Exon/intron boundaries of EFEMP1 were used as boundaries of functional modules in constructing EFEMP1 variants, with removal of various module(s), and/or mutating an amino acid residue to convert a weak integrin binding-site into a strong one. A series of in vitro assays on cancerous features, and subcutaneous and intracranial xenograft-formation assays, were carried out for effects from overexpression of wild-type and variant forms of EFEMP1 in two glioma subpopulations characterized as tumor mass-forming cells (TMCs) or stem-like tumor initiating cells (STICs), where EFEMP1 showed cellcontext- dependent dual functions. One of the EFEMP1 variants was identified as the sought-after ETSP, which had a stronger tumor-suppression function in TMCs by targeting EGFR and angiogenesis, and a new tumor-suppression function in STICs by targeting NOTCH signaling and MMP2-mediated cell invasion. Therefore, ETSP may form the basis for further important research to develop a novel cancer therapy to treat many types of cancer by its tumor suppressor effect in the extracellular matrix compartment.

AB - Prostate cancer (PCa) is the sixth highest causes of cancer-related deaths in men. The molecular events underlying its behavior and evolution are not completely understood. Prostate-specific antigen (PSA) is the only approved Food and Drug Administration biomarker. A panel of ten stage-specific tumoral and adjacent non tumoral tissues from patients affected by PCa (Gleason score 6, 3+3; PSA 10 /19 ng/ml) was investigated by MS-based proteomics approach. The proposed method was based on identifying the base-soluble proteins from tissue, established an efficient study, which lead to a deeper molecular perspective understanding of the PCa. A total of 164 proteins were found and 132 of these were evaluated differentially expressed in tumoral tissues. The Ingenuity Pathway Analysis (IPA) showed that among all dataset obtained, 105 molecules were involved in epithelial neoplasia with a p-value of 3.62E-05, whereas, only 11 molecules detected were ascribed to sentinel tissue and bodily fluids.

AB - The angiogenic inducer CCN1 (Cysteine-rich 61, CYR61) is differentially activated in metastatic breast carcinomas. However, little is known about the precise mechanisms that underlie the pro-metastatic actions of CCN1. Here, we investigated the impact of CCN1 expression on fatty acid synthase (FASN), a metabolic oncogene thought to provide cancer cells with proliferative and survival advantages. Forced expression of CCN1 in MCF-7 cells robustly up regulated FASN protein expression and also significantly increased FASN gene promoter activity 2- to 3-fold, whereas deletion of the sterol response element binding protein (SREBP) binding site in the FASN promoter completely abrogated CCN1-driven transcriptional activation. Pharmacological blockade of MAPK or PI 3'K activation similarly prevented the ability of CCN1 to induce FASN gene activation. Pharmacological inhibition of FASN activity with the mycotoxin cerulenin or the small compound C75 reversed CCN1-induced acquisition of estrogen independence and resistance to hormone therapies such as tamoxifen and fulvestrant in anchorage-independent growth assays. This study uncovers FASNdependent endogenous lipogenesis as a new mechanism controlling the metastatic phenotype promoted by CCN1. Because estrogen independence and progression to a metastatic phenotype are hallmarks of therapeutic resistance and mortality in breast cancer, this previously unrecognized CCN1-driven lipogenic phenotype represents a novel metabolic target to clinically manage metastatic disease progression.

AB - The control of human bipedal locomotion is of great interest to the field of lower-body brain computer interfaces (BCIs) for rehabilitation of gait. While the feasibility of a closed-loop BCI system for the control of a lower body exoskeleton has been recently shown, multi-day closed-loop neural decoding of human gait in a virtual reality (BCI-VR) environment has yet to be demonstrated. In this study, we propose a real-time closed-loop BCI that decodes lower limb joint angles from scalp electroencephalography (EEG) during treadmill walking to control the walking movements of a virtual avatar. Moreover, virtual kinematic perturbations resulting in asymmetric walking gait patterns of the avatar were also introduced to investigate gait adaptation using the closed-loop BCI-VR system over a period of eight days. Our results demonstrate the feasibility of using a closed-loop BCI to learn to control a walking avatar under normal and altered visuomotor perturbations, which involved cortical adaptations. These findings have implications for the development of BCI-VR systems for gait rehabilitation after stroke and for understanding cortical plasticity induced by a closed-loop BCI system.

AB - Recurrence and progression to higher grade lesions are key biological events and characteristic behaviors in the evolution process of glioma. Malignant astrocytic tumors such as glioblastoma (GBM) are the most lethal intracranial tumors. However, the clinical practicability and significance of molecular parameters for the diagnostic and prognostic prediction of astrocytic tumors is still limited. In this study, we detected ATRX, IDH1-R132H and Ki-67 by immunohistochemistry and observed the association of IDH1-R132H with ATRX and Ki-67 expression. There was a strong association between ATRX loss and IDH1-R132H (p<0.0001). However, Ki-67 high expression restricted in the tumors with IDH1-R132H negative (p=0.0129). Patients with IDH1-R132H positive or ATRX loss astrocytic tumors had a longer progressive- free survival (p<0.0001, p=0.0044, respectively). High Ki-67 expression was associated with shorter PFS in patients with astrocytic tumors (p=0.002). Then we characterized three prognostic subgroups of astrocytic tumors (referred to as A1, A2 and A3). The new model demonstrated a remarkable separation of the progression interval in the three molecular subgroups and the distribution of patients' age in the A1-A2-A3 model was also significant different. This model will aid predicting the overall survival and progressive time of astrocytic tumors' patients.

AB - Ten annotated 3D reconstructions of Montipora capitata coral colonies contain x,y,z coordinates for all growth anomaly (GA) lesions affecting these corals. The 3D reconstructions are available as Virtual Reality Modeling Language (VRML) files, and the GA lesions coordinates are in accompanying text files. The VRML models and GA lesion coordinates can be spatially analyzed using Matlab. Matlab scripts are provided for three spatial statistical procedures in order to assess clustering of the GA lesions across the coral colony surfaces in a 3D framework: Ripley's K, Moran's I, and the Kolmogorov-Smirnov test.

PMID- 27713921 TI - Predicting later life health status and mortality using state-level socioeconomic characteristics in early life. AB - Studies extending across multiple life stages promote an understanding of factors influencing health across the life span. Existing work has largely focused on individual-level rather than area-level early life determinants of health. In this study, we linked multiple data sets to examine whether early life state level characteristics were predictive of health and mortality decades later. The sample included 143,755 U.S. employees, for whom work life claims and administrative data were linked with early life state-of-residence and mortality. We first created a "state health risk score" (SHRS) and "state mortality risk score" (SMRS) by modeling state-level contextual characteristics with health status and mortality in a randomly selected 30% of the sample (the "training set"). We then examined the association of these scores with objective health status and mortality in later life in the remaining 70% of the sample (the "test set") using multivariate linear and Cox regressions, respectively. The association between the SHRS and adult health status was beta=0.14 (95%CI: 0.084, 0.20), while the hazard ratio for the SMRS was 0.96 (95%CI: 0.93, 1.00). The association between the SHRS and health was not statistically significant in older age groups at a p-level of 0.05, and there was a statistically significantly different association for health status among movers compared to stayers. This study uses a life course perspective and supports the idea of "sensitive periods" in early life that have enduring impacts on health. It adds to the literature examining populations in the U.S. where large linked data sets are infrequently available.

PMID- 27713923 TI - The miR-132/212 locus: a complex regulator of neuronal plasticity, gene expression and cognition. AB - The microRNA (miRNA) class of small (typically 22-24 nt) non-coding RNA affects a wide range of physiological processes in the mammalian central nervous system (CNS). By acting as potent regulators of mRNA translation and stability, miRNAs fine-tune the expression of a multitude of genes that play critical roles in complex cognitive processes, including learning and memory. Of note, within the CNS, miRNAs can be expressed in an inducible, and cell-type specific manner. Here, we provide a brief overview of the expression and functional effects of the miR-132/212 gene locus in forebrain circuits of the CNS, and then discuss a recent publication that explored the contributions of miR-132 and miR-212 to cognition and to transcriptome regulation. We also discuss mechanisms by which synaptic activity regulates miR-132/212 expression, how miR-132 and miR-212 affect neuronal plasticity, and how the dysregulation of these two miRNAs could contribute to the development of cognitive impairments. PMID- 27713925 TI - Time scale bias in erosion rates of glaciated landscapes. AB - Deciphering erosion rates over geologic time is fundamental for understanding the interplay between climate, tectonic, and erosional processes. Existing techniques integrate erosion over different time scales, and direct comparison of such rates is routinely done in earth science. On the basis of a global compilation, we show that erosion rate estimates in glaciated landscapes may be affected by a systematic averaging bias that produces higher estimated erosion rates toward the present, which do not reflect straightforward changes in erosion rates through time. This trend can result from a heavy-tailed distribution of erosional hiatuses (that is, time periods where no or relatively slow erosion occurs). We argue that such a distribution can result from the intermittency of erosional processes in glaciated landscapes that are tightly coupled to climate variability from decadal to millennial time scales. In contrast, we find no evidence for a time scale bias in spatially averaged erosion rates of landscapes dominated by river incision. We discuss the implications of our findings in the context of the proposed coupling between climate and tectonics, and interpreting erosion rate estimates with different averaging time scales through geologic time. PMID- 27713924 TI - Empirical observations of the spawning migration of European eels: The long and dangerous road to the Sargasso Sea. AB - The spawning migration of the European eel (Anguilla anguilla L.) to the Sargasso Sea is one of the greatest animal migrations. However, the duration and route of the migration remain uncertain. Using fishery data from 20 rivers across Europe, we show that most eels begin their oceanic migration between August and December. We used electronic tagging techniques to map the oceanic migration from eels released from four regions in Europe. Of 707 eels tagged, we received 206 data sets. Many migrations ended soon after release because of predation events, but we were able to reconstruct in detail the migration routes of >80 eels. The route extended from western mainland Europe to the Azores region, more than 5000 km toward the Sargasso Sea. All eels exhibited diel vertical migrations, moving from deeper water during the day into shallower water at night. The range of migration speeds was 3 to 47 km day-1. Using data from larval surveys in the Sargasso Sea, we show that spawning likely begins in December and peaks in February. Synthesizing these results, we show that the timing of autumn escapement and the rate of migration are inconsistent with the century-long held assumption that eels spawn as a single reproductive cohort in the springtime following their escapement. Instead, we suggest that European eels adopt a mixed migratory strategy, with some individuals able to achieve a rapid migration, whereas others arrive only in time for the following spawning season. Our results have consequences for eel management. PMID- 27713926 TI - The social costs of nitrogen. AB - Despite growing recognition of the negative externalities associated with reactive nitrogen (N), the damage costs of N to air, water, and climate remain largely unquantified. We propose a comprehensive approach for estimating the social cost of nitrogen (SCN), defined as the present value of the monetary damages caused by an incremental increase in N. This framework advances N accounting by considering how each form of N causes damages at specific locations as it cascades through the environment. We apply the approach to an empirical example that estimates the SCN for N applied as fertilizer. We track impacts of N through its transformation into atmospheric and aquatic pools and estimate the distribution of associated costs to affected populations. Our results confirm that there is no uniform SCN. Instead, changes in N management will result in different N-related costs depending on where N moves and the location, vulnerability, and preferences of populations affected by N. For example, we found that the SCN per kilogram of N fertilizer applied in Minnesota ranges over several orders of magnitude, from less than $0.001/kg N to greater than $10/kg N, illustrating the importance of considering the site, the form of N, and end points of interest rather than assuming a uniform cost for damages. Our approach for estimating the SCN demonstrates the potential of integrated biophysical and economic models to illuminate the costs and benefits of N and inform more strategic and efficient N management. PMID- 27713927 TI - Relative impacts of mitigation, temperature, and precipitation on 21st-century megadrought risk in the American Southwest. AB - Megadroughts are comparable in severity to the worst droughts of the 20th century but are of much longer duration. A megadrought in the American Southwest would impose unprecedented stress on the limited water resources of the area, making it critical to evaluate future risks not only under different climate change mitigation scenarios but also for different aspects of regional hydroclimate. We find that changes in the mean hydroclimate state, rather than its variability, determine megadrought risk in the American Southwest. Estimates of megadrought probabilities based on precipitation alone tend to underestimate risk. Furthermore, business-as-usual emissions of greenhouse gases will drive regional warming and drying, regardless of large precipitation uncertainties. We find that regional temperature increases alone push megadrought risk above 70, 90, or 99% by the end of the century, even if precipitation increases moderately, does not change, or decreases, respectively. Although each possibility is supported by some climate model simulations, the latter is the most common outcome for the American Southwest in Coupled Model Intercomparison 5 generation models. An aggressive reduction in global greenhouse gas emissions cuts megadrought risks nearly in half. PMID- 27713928 TI - Quantum optical rotatory dispersion. AB - The phenomenon of molecular optical activity manifests itself as the rotation of the plane of linear polarization when light passes through chiral media. Measurements of optical activity and its wavelength dependence, that is, optical rotatory dispersion, can reveal information about intricate properties of molecules, such as the three-dimensional arrangement of atoms comprising a molecule. Given a limited probe power, quantum metrology offers the possibility of outperforming classical measurements. This has particular appeal when samples may be damaged by high power, which is a potential concern for chiroptical studies. We present the first experiment in which multiwavelength polarization entangled photon pairs are used to measure the optical activity and optical rotatory dispersion exhibited by a solution of chiral molecules. Our work paves the way for quantum-enhanced measurements of chirality, with potential applications in chemistry, biology, materials science, and the pharmaceutical industry. The scheme that we use for probing wavelength dependence not only allows one to surpass the information extracted per photon in a classical measurement but also can be used for more general differential measurements. PMID- 27713930 TI - Intracellular pH-Induced Tip-to-Tip Assembly of Gold Nanorods for Enhanced Plasmonic Photothermal Therapy. AB - The search for efficient plasmonic photothermal therapies using nonharmful pulse laser irradiation at the near-infrared (NIR) is fundamental for biomedical cancer research. Therefore, the development of novel assembled plasmonic gold nanostructures with the aim of reducing the applied laser power density to a minimum through hot-spot-mediated cell photothermolysis is an ongoing challenge. We demonstrate that gold nanorods (Au NRs) functionalized at their tips with a pH sensitive ligand assemble into oligomers within cell lysosomes through hydrogen bonding attractive interactions. The unique intracellular features of the plasmonic oligomers allow us to significantly reduce the femtosecond laser power density and Au NR dose while still achieving excellent cell killing rates. The formation of gold tip-to-tip oligomers with longitudinal localized surface plasmon resonance bands at the NIR, obtained from low-aspect-ratio Au NRs close in resonance with 800 nm Ti:sapphire 90 fs laser pulses, was found to be the key parameter for realizing the enhanced plasmonic photothermal therapy. PMID- 27713929 TI - Intrinsic Functional Connectivity in Attention-Deficit/Hyperactivity Disorder: A Science in Development. AB - Functional magnetic resonance imaging (fMRI) without an explicit task, i.e., resting state fMRI, of individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) is growing rapidly. Early studies were unaware of the vulnerability of this method to even minor degrees of head motion, a major concern in the field. Recent efforts are implementing various strategies to address this source of artifact along with a growing set of analytical tools. Availability of the ADHD 200 Consortium dataset, a large-scale multi-site repository, is facilitating increasingly sophisticated approaches. In parallel, investigators are beginning to explicitly test the replicability of published findings. In this narrative review, we sketch out broad, overarching hypotheses being entertained while noting methodological uncertainties. Current hypotheses implicate the interplay of default, cognitive control (frontoparietal) and attention (dorsal, ventral, salience) networks in ADHD; functional connectivities of reward-related and amygdala-related circuits are also supported as substrates for dimensional aspects of ADHD. Before these can be further specified and definitively tested, we assert the field must take on the challenge of mapping the "topography" of the analytical space, i.e., determining the sensitivities of results to variations in acquisition, analysis, demographic and phenotypic parameters. Doing so with openly available datasets will provide the needed foundation for delineating typical and atypical developmental trajectories of brain structure and function in neurodevelopmental disorders including ADHD when applied to large-scale multi site prospective longitudinal studies such as the forthcoming Adolescent Brain Cognitive Development study.

The assay was validated in cell culture lysates from breast cancer cells and in serum from a mouse model of breast cancer. PMID- 27713931 TI - Free Energy-Based Virtual Screening and Optimization of RNase H Inhibitors of HIV 1 Reverse Transcriptase. AB - We report the results of a binding free energy-based virtual screening campaign of a library of 77 alpha-hydroxytropolone derivatives against the challenging RNase H active site of the reverse transcriptase (RT) enzyme of human immunodeficiency virus-1. Multiple protonation states, rotamer states, and binding modalities of each compound were individually evaluated. The work involved more than 300 individual absolute alchemical binding free energy parallel molecular dynamics calculations and over 1 million CPU hours on national computing clusters and a local campus computational grid. The thermodynamic and structural measures obtained in this work rationalize a series of characteristics of this system useful for guiding future synthetic and biochemical efforts. The free energy model identified key ligand-dependent entropic and conformational reorganization processes difficult to capture using standard docking and scoring approaches. Binding free energy-based optimization of the lead compounds emerging from the virtual screen has yielded four compounds with very favorable binding properties, which will be the subject of further experimental investigations. This work is one of the few reported applications of advanced-binding free energy models to large-scale virtual screening and optimization projects. It further demonstrates that, with suitable algorithms and automation, advanced-binding free energy models can have a useful role in early-stage drug-discovery programs. PMID- 27713933 TI - Conformational Changes in High-Density Lipoprotein Nanoparticles Induced by High Payloads of Paramagnetic Lipids. AB - High-density lipoprotein (HDL) nanoparticles doped with gadolinium lipids can be used as magnetic resonance imaging diagnostic agents for atherosclerosis. In this study, HDL nanoparticles with different molar fractions of gadolinium lipids (0 < xGd-lipids < 0.33) were prepared, and the MR relaxivity values (r1 and r2) for all compositions were measured. Both r1 and r2 parameters reached a maximal value at a molar fraction of approximately xGd-lipids = 0.2. Higher payloads of gadolinium did not significantly increase relaxivity values but induced changes in the structure of HDL, increasing the size of the particles from dH = 8.2 +/- 1.6 to 51.7 +/- 7.3 nm. High payloads of gadolinium lipids trigger conformational changes in HDL, with potential effects on the in vivo behavior of the nanoparticles. PMID- 27713936 TI - The reactivity of platinum microelectrodes. AB - Despite the widespread application of ultramicroelectrodes (UMEs), the customary method of their electrochemical characterization via outer sphere redox probing has serious limitations. In this study we provide additional insights into this subject by measuring not only outer sphere redox couples, but also blank voltammetries and the reactivity towards various catalytic reactions of Pt UMEs. The data for the UMEs are compared to those for macroscale Pt electrodes that can be flame-annealed. Although the reactivity is similar for reactions that are rather insensitive to the surface structure (and/or composition), UMEs perform much worse for more surface sensitive catalytic reactions. This effect can be explained by the UMEs being contaminated much faster, though it remains to be established if the origin of this contamination lies in the preparation method or in the impurities in the (high-purity grade) chemicals used. Our study recommends that catalytic reactivity measurements on ultramicroelectrodes should always be accompanied by blank voltammetries and the results have to be interpreted extremely carefully.

PMID- 27713938 TI - Effects of extending the pi-conjugation of the acetylide ligand on the photophysics and reverse saturable absorption of Pt(ii) bipyridine bisacetylide complexes. AB - The synthesis and photophysics of four platinum(ii) bipyridine (bpy) bisacetylide complexes with different degrees of pi-conjugation and an electron-donating diphenylamino (NPh2) or electron-withdrawing benzothiazolyl (BTZ) terminal substituent on the acetylide ligands are reported. The UV-vis absorption spectra of these complexes are composed of intense ligand-localized 1pi,pi* transitions at 330-430 nm and broad, moderately strong ligand-to-ligand charge transfer/metal to-ligand charge transfer (1LLCT/1MLCT) transitions at 430-530 nm. All complexes are phosphorescent in solutions at room temperature and exhibit very broad and moderately strong triplet excited-state absorption in the visible to the NIR spectral region (425-800 nm). It is found that extending the pi-conjugation of the acetylide ligands via adding one or two more ethynylfluorenyl unit(s) to the acetylide ligand does not change the energies of the 1pi,pi* and 1LLCT/1MLCT transitions pronouncedly except for increasing the molar extinction coefficients of the 1pi,pi* transitions. The emitting triplet excited states of the four complexes are the 3MLCT/3LLCT states and have the same energy. However, the complex that contains the tris(ethynylfluorenyl) units and the terminal NPh2 substituent on the acetylide ligand exhibits longer triplet lifetimes than the corresponding complex that has the bis(ethynylfluorenyl) units. The transient absorption band maxima of the complexes with tris(ethynylfluorenyl) units are slightly red-shifted in comparison to those of their respective counterparts with bis(ethynylfluorenyl) units. The nature of the terminal substituent does not influence the parentage and energies of the lowest singlet and triplet excited states. However, the triplet excited-state lifetimes of the complexes with the NPh2 terminal substituent on the bis(ethynylfluorenyl) or tris(ethynylfluorenyl) ligands are much longer than that of their counterpart with monofluorenylacetylide ligands; while the triplet lifetimes of the complexes containing the BTZ terminal substituent are similar to their counterpart with monofluorenylacetylide ligands. All complexes exhibit strong reverse saturable absorption (RSA) at 532 nm for nanosecond laser pulses.

Solvent-exchange compounds of 3.CH3OH, [(MeTp)FeIII(CN)3]2[FeII(tpa)]2.2ClO4.2H2O (3.2H2O), and their solvent-free form (2 and 3) are also obtained, respectively. The spin crossover (SCO) properties of all compounds are confirmed by detailed structural analyses of the coordination environments of the FeII centres and magnetic susceptibility measurements. All compounds exhibit SCO behaviour near room temperature (T1/2 = 320 K for 2.H2O; 302 K for 2; 292 K for 3.CH3OH; 306 K for 3.2H2O and 290 K for 3) and reversible single-crystal to single-crystal (SC-SC) transformations induced by guest desorption and resorption or solvent exchange. The transition temperature close to room temperature can be tuned by the dehydration and re hydration processes. The structure-property analysis discloses that the distorted {Fe4(MU-CN)4} core and deviations of bent ?Fe-N[triple bond, length as m-dash]C angles play a key role in tuning the transition temperature of these similar mixed-valence {FeFe} complexes.

PMID- 27713943 TI - The influence of the dianhydride precursor in hyper-cross-linked hybrid polyPOSS imide networks. AB - Hybrid organic/inorganic hyper-cross-linked membranes based on imides covalently bonded with polyhedral oligomeric silsesquioxanes (POSS) have recently been developed for gas-separation applications under high pressure and/or temperature conditions. Their molecular sieving capabilities have been shown to depend on the nature of the organic dianhydride precursor. In the present work, realistic molecular models of such polyPOSS-imide films based on the flexible 6FDA dianhydride are compared to those based on the shorter and more rigid PMDA dianhydride. The models creation procedure closely mimicks the mixing, polycondensation and imidization steps of the experimental scheme. The resulting networks are found to be highly heterogeneous in terms of both the number of links (from zero to the maximum possible of eight per POSS cage with an average of four) and their structure (interPOSS, intraPOSS, single-links, double-links) because of the eight-equivalent-arms nature of the POSS precursor. For both dianhydride precursors, crosslinking with POSS and the subsequent imidization step decrease the density, create additional void-space and increase the solubility of the resulting membranes. However, when compared to PMDA, the added flexibility of the central 6FDA bridge leads to a larger thermally-induced dilation of the networks and a larger volume loss per H2O over the imidization step. With their better ability to redensify and to adapt to the added constraints, the cagecage distances and cage(organic bridge)cage angles in the 6FDA polyPOSS-imides span a larger range than in their PMDA counterparts. In addition, the stiffness of the PMDA moiety results in more unrelaxed free volume remaining trapped in the PMDA polyPOSS-imides upon imidization, and as such, to significantly more open structures with less favourable interactions. As expected from their enhanced flexibility, the thermomechanical properties of the 6FDA networks are slightly lower than those based on PMDA. However, the better mechanical resistance of PMDA over 6FDA does not really become significant before very large volume dilations.

AB - Kramers' turnover theory, based on the dynamics of the collective unstable normal mode (also known as PGH theory), is extended to the motion of a particle on a periodic potential interacting bilinearly with a dissipative harmonic bath. This is achieved by considering the small parameter of the problem to be the deviation of the collective bath mode from its value along the reaction coordinate, defined by the unstable normal mode. With this change, the effective potential along the unstable normal mode remains periodic, albeit with a renormalized mass, or equivalently a renormalized lattice length. Using second order classical perturbation theory, this not only enables the derivation of the hopping rates and the diffusion coefficient, but also the derivation of finite barrier corrections to the theory. The analytical results are tested against numerical simulation data for a simple cosine potential, ohmic friction, and different reduced barrier heights.

AB - Piceatannol (3,3',4',5-trans-tetrahydroxystilbene) is a polyphenolic compound abundant in the seeds of passion fruit (Passiflora edulis). Piceatannol is an analogue of resveratrol (3,4',5-trans-trihydroxystilbene) and shares the structural motif and biological activities such as activation of SIRT1. Several studies have shown that piceatannol is more potent than resveratrol. In this study, we examined the effects of piceatannol on neural stem cell differentiation into astrocytes compared with those of resveratrol. At a concentration of 2.5 MUM, piceatannol promoted astrocyte differentiation, while resveratrol had no effect at this concentration. Furthermore, we found that oral administration of piceatannol increased the number of astrocytes in the brains of adult mice, while resveratrol administration showed no effects. These results suggest that piceatannol has a superior effect to resveratrol in promoting astrocyte differentiation.

AB - Barrett's oesophagus (BE) is a premalignant condition that can progress to oesophageal adenocarcinoma. Endoscopic surveillance aims to identify potential progression at an early, treatable stage, but generates large numbers of tissue biopsies. Fourier transform infrared (FTIR) mapping was used to develop an automated histology tool for detection of BE and Barrett's neoplasia in tissue biopsies. 22 oesophageal tissue samples were collected from 19 patients. Contiguous frozen tissue sections were taken for pathology review and FTIR imaging. 45 mid-IR images were measured on an Agilent 620 FTIR microscope with an Agilent 670 spectrometer. Each image covering a 140 MUm * 140 MUm region was measured in 5 minutes, using a 1.1 MUm2 pixel size and 64 scans per pixel. Principal component fed linear discriminant analysis was used to build classification models based on spectral differences, which were then tested using leave-one-sample-out cross validation. Key biochemical differences were identified by their spectral signatures: high glycogen content was seen in normal squamous (NSQ) tissue, high glycoprotein content was observed in glandular BE tissue, and high DNA content in dysplasia/adenocarcinoma samples. Classification of normal squamous samples versus 'abnormal' samples (any stage of Barrett's) was performed with 100% sensitivity and specificity. Neoplastic Barrett's (dysplasia or adenocarcinoma) was identified with 95.6% sensitivity and 86.4% specificity. Highly accurate pathology classification can be achieved with FTIR measurement of frozen tissue sections in a clinically applicable timeframe.

AB - Zinc is an essential micronutrient that strongly influences human health and nutrition through its involvement in several biological processes. Zinc functions as structural and functional component of many transcription factors and enzymes that regulate cell growth, gene expression, and immune response, and its deficiency can lead to retarded growth and impaired immune functions. The physiological functions of zinc are dependent on its bioavailability in tissues, which in turn depends on intestinal absorption of dietary zinc. The presence of dietary fibre and phytates impedes intestinal zinc absorption, as they can form insoluble complexes with zinc, decreasing its bioavailability. Peptides derived from food proteins can enhance zinc absorption and bioavailability. Peptides that contain amino acid residues such as cysteine, histidine, serine, aspartate and glutamate can chelate divalent metals, including zinc, forming soluble metal coordinate complexes. The structure-function relationship of zinc-chelating peptides and the stability of the peptide-metal complexes to gastrointestinal digestion are critical to their relevance in human nutrition and health promotion.

AB - Multiple sclerosis (MS) is a demyelinating disease occurring in the central nervous system. In the present study, we evaluated the function of myricetin on the alleviation of behavioral dysfunction and myelin protection in the cuprizone induced demyelination model. Mice were daily fed with fodder including 0.2% cuprizone and were administrated myricetin (100 mg kg-1) by gavage administration for 5 weeks. The treatment of myricetin ameliorated hyper-locomotion and behavior impairment induced by cuprizone toxicity. With the administration of myricetin, the demyelinating lesion was lessened via increasing the LFB staining area and myelin phosphatide protein (MBP) expression. In addition, myricetin evidently promoted Nrf2 translocation in the nuclear fraction and enhanced the HO-1 and NQO1 expression levels. Our data revealed that myricetin may be a potential candidate for mitigating motor defects and demyelination in a cuprizone-induced mouse model via activating the Nrf2 pathway. PMID- 27713954 TI - Anti-inflammatory activities of essential oil isolated from the calyx of Hibiscus sabdariffa L. AB - Hibiscus sabdariffa Linn., belonging to the family of Malvaceae, is considered to be a plant with health care applications in China. The main purpose of this study was to analyze the composition of its essential oil and assess its potential therapeutic effect on anti-inflammatory activity. A water steam distillation method was used to extract the essential oil from H. Sabdariffa. The essential oil components were determined by gas chromatography/mass spectrometry (GC-MS) analysis and a total of 18 volatile constituents were identified, the majority of which were fatty acids and ester compounds. Biological activity showed that the essential oil extracted from H. Sabdariffa exhibited excellent anti-inflammatory activity in lipopolysaccharide (LPS)-stimulated macrophage RAW 264.7 cells. The nitric oxide (NO) inhibition rate reached 67.46% when the concentration of the essential oil was 200 MUg mL-1. Further analysis showed that the anti inflammatory activity of the essential oil extracted from H. Sabdariffa might be exerted through inhibiting the activation of NF-kappaB and MAPK (JNK and ERK1/2) signaling pathways to decrease NO and pro-inflammatory cytokine (IL-1, IL-6, TNF alpha, COX-2, and iNOS) production. Thus, the essential oil extracted from H. Sabdariffa is a good source of a natural product with a beneficial effect against inflammation, and it may be applied as a food supplement and/or functional ingredient. PMID- 27713955 TI - Bolus matters: the influence of food oral breakdown on dynamic texture perception. AB - This review article focuses on design of food structure, characterisation of oral processing by boli characterisation and dynamic texture perception. Knowledge of the food properties governing bolus formation and bolus properties determining temporal changes in texture perception is of major importance. Such knowledge allows academia to better understand the mechanisms underlying texture perception and food industry to improve product texture. For instance, such knowledge can be used for developing foods with desired texture perception that fit in a healthy diet or that are customized to specific consumer groups. The end point of oral processing is the formation of a safe-to-swallow bolus. The transitions of solid and soft solid foods into bolus are accompanied by tremendous modifications of food properties. The review discusses dynamic changes in bolus properties resulting in dynamic changes of texture perception during oral processing. Studies monitoring chewing behaviour are discussed to complement the relationships between bolus properties and dynamic texture perception. We conclude that texture perception evolves over mastication time and depends on food properties, such as mechanical properties, mainly in the beginning of oral processing. Towards the middle and end of oral processing, bolus properties depend on food properties and explain texture perception better than food properties. PMID- 27713956 TI - Lipidomic approach in young adult triathletes: effect of supplementation with a polyphenols-rich juice on neuroprostane and F2-dihomo-isoprostane markers. AB - The aim of the this study was to determine the effect of a polyphenols-rich juice (aronia-citrus juice, ACJ) on F4-neuroprostanes and F2-dihomo-isoprostanes markers of oxidative stress associated with the central nervous system (CNS)-in 16 elite triathletes under a controlled diet for triathlon training (145 days). In the triathletes, a decrease of the lipid peroxidation markers after ACJ intake, associated with neuronal membrane degradation (10-epi-10-F4t neuroprostane and 10-F4t-neuroprostane), was observed when compared with placebo stage values. Regarding the F2-dihomo-isoprostanes, a significant decrease of the neuromotor system damage biomarkers (17-F2t-dihomo-isoprostane) with an increase of training load during the study was observed, although the decrease of the load training at the last stage showed a significant increase of the values of ent-7 (RS)-7-F2t-dihomo-IsoP, suggesting a possible role in adaptation post-training. On the other hand, the changes in the excretion of 17-epi-17-F2t-dihomo-IsoP provided a positive connection between physical exercise and ACJ intake. Thus, the results showed in this clinical study in young triathletes will help to elucidate novel interactions and mechanisms between the excretion of lipid peroxidation metabolites from CNS, supplementation of polyphenols-rich juice in the diet and physical exercise during a training season. PMID- 27713957 TI - Antidiabetic (type 2) effects of Lactobacillus G15 and Q14 in rats through regulation of intestinal permeability and microbiota. AB - The antidiabetic effects of Lactobacillus. paracasei subsp. paracasei G15 and Lactobacillus. casei Q14 in high fat diet and streptozotocin-induced type 2 diabetic (T2D) rats were evaluated in this study. The strains were separated from Chinese traditional fermented dairy food. Administration of G15 and Q14 for 6 weeks significantly improved the glucose tolerance and reduced the HbA1c levels in T2D rats. The probiotic treatment reduced the intestinal mucosal permeability and improved the epithelial barrier function through modification of the gut microbiota, which in turn lowered circulating LPS and inflammation cytokines, including IL-1beta and IL-8, and eventually alleviated the inflammatory status and islet beta-cell dysfunction. Combination of Q14 and metformin reversed the thymic atrophy and both G15 and Q14 lowered the circulating IL-6 level, indicating the immune-modulating potential of the strains. Lactobacillus. paracasei subsp. paracasei G15 and Lactobacillus. casei Q14 provide an insight into the biotherapy application of traditional fermented foods and their functional ingredients in the treatment of diabetes. PMID- 27713958 TI - Laminarin favorably modulates gut microbiota in mice fed a high-fat diet. AB - We investigated the anti-obesity effects of the potential prebiotic, laminarin, on mice fed a high-fat diet. A metagenomics approach was applied to characterize the ecological and functional differences of gut microbiota among mice fed a normal diet (CTL), a high-fat diet (HFD), and a laminarin-supplemented high-fat diet (HFL). The HFL mice showed a slower weight gain than the HFD mice during the laminarin-feeding period, but the rate of weight gain increased after the termination of laminarin supplementation. Gut microbial community analysis showed clear differences between the CTL and HFD mice, whereas the HFL mice were between the two. A higher abundance of carbohydrate active enzymes was observed in the HFL mice compared to the HFD mice, with especially notable increases in glycoside hydrolase and polysaccharide lyases. A significant decrease in Firmicutes and an increase in the Bacteroidetes phylum, especially the genus Bacteroides, were observed during laminarin ingestion. Laminarin ingestion altered the gut microbiota at the species level, which was re-shifted after termination of laminarin ingestion. Therefore, supplementing laminarin could reduce the adverse effects of a high-fat diet by shifting the gut microbiota towards a higher energy metabolism. Thus, laminarin could be used to develop anti-obesity functional foods. Our results also suggest that laminarin would need to be consumed regularly in order to prevent or manage obesity. PMID- 27713959 TI - A chitosan-coated liposome encapsulating antibacterial peptide, Apep10: characterisation, triggered-release effects and antilisterial activity in thaw water of frozen chicken. AB - Contamination of Listeria monocytogenes in food and their processing environment is a focus of attention in the food industry. To achieve the controlled release of antibacterial agents to a food processing environment contaminated by L. monocytogenes, chitosan-stabilised liposomes encapsulating Apep10 (GLARCLAGTL), an antibacterial peptide derived from boiled-dried anchovies, were prepared by utilising listeria toxins to activate the peptide release. Characteristics including the particle size, polydispersity index (PDI), encapsulation efficiency (EE), and morphology of the chitosan-coated Apep10 liposomes were investigated. The chitosan liposomes were more stable than their uncoated counterparts, which indicated that the coating of chitosan on the surface of the liposomes inhibited undesirable vesicle fusion and payload release during storage. However, once the chitosan-stabilised liposomes encountered L. monocytogenes, which secretes pore forming toxins, the encapsulated antibacterial peptide was released and it exerted antimicrobial effects on the strain. The results of time-kill inhibition, scanning electron microscopy (SEM), crystal violet staining and confocal laser scanning microscopy (CLSM) images demonstrated that these liposomes have favourable antibacterial and anti-biofilm activities against L. monocytogenes in the thaw water of frozen chicken. This bacterial toxin-enabled release of the encapsulated antibacterial peptide from chitosan-coated liposomes provides an effective approach for the control of listerial contamination. This technique can be broadly applied to treat contamination by a variety of pathogens that secrete pore-forming toxins. PMID- 27713960 TI - Hypouricemic effects of Mesona procumbens Hemsl. through modulating xanthine oxidase activity in vitro and in vivo. AB - Uric acid is a metabolite obtained from purine by xanthine oxidase activity (XO) and high levels of serum uric acid leads to hyperuricemia and gout. Mesona procumbens Hemsl. has been used as a healthy beverage and a traditional remedy. In this study, the hypouricemic effects of M. procumbens extracts were evaluated in vitro and in vivo. The 50% ethanol extract of M. procumbens (EE50) showed the strongest inhibitory effect on monosodium urate (MSU)-induced XO activity in THP 1 cells. However, the phenolics and flavonoids in EE50 may not serve as inhibitors of XO. EE50 prevented an increase in the serum uric acid level in potassium oxonate (PO)-challenged ICR mice and streptozocin (STZ)-induced SD rats. EE50 down-regulated STZ-induced liver XO activity, and it restored renal OAT1 and urate transporter expression. STZ-induced renal interleukin-1beta (IL 1beta) and the tumor necrosis factor-alpha (TNF-alpha) level were inhibited by EE50 treatment. EE50 exhibits the hypouricemic effect via down-regulation of XO activity, suggesting that EE50 has potential to improve hyperuricemia and its complications. PMID- 27713961 TI - Anti-cancer properties of olive oil secoiridoid phenols: a systematic review of in vivo studies. AB - Epidemiological studies suggest that olive oil intake is associated to a reduced risk of cancer. Recently, the chemopreventive activity of olive oil has been attributed to its unique phenolic compounds represented by phenolic alcohols, hydroxytyrosol (3,4-dihydroxyphenylethanol: 3,4-DHPEA) and tyrosol (p hydroxyphenylethanol: p-HPEA), and their secoiridoid derivatives 3,4-DHPEA-EA (oleuropein aglycon), p-HPEA-EA (ligstroside aglycon), 3,4-DHPEA-EDA, p-HPEA-EDA (oleocanthal), and oleuropein. Several studies have demonstrated that these compounds are able to inhibit proliferation and induce apoptosis in different tumor cell lines. These in vitro effects have been recently summarized in several reviews. The aim of this systematic review was to evaluate the in vivo anti cancer activities of secoiridoid phenols as evidenced by either animal models of carcinogenesis or human intervention trials. From the literature research through "PubMed" and "Web of Science", 16 animal studies and 5 human intervention trials were identified and included in the review. Most of the animal studies have confirmed the ability of these compounds to inhibit the carcinogenesis process at both initiation and promotion/progression phases. All human intervention trials have investigated the effects of olive oil phenols on DNA damage. Among the five selected studies, three have shown a significant preventive effect on oxidative DNA damage in terms of reduction of 8-oxo-7,8-dihydro-2'-deoxyguanosine in urine, in mitochondria DNA of mononuclear cells and in lymphocyte DNA. The other two studies failed to see an effect on the urinary excretion of either etheno-DNA adducts or oxidation products of guanine. Further investigations are necessary to clarify the real chemopreventive potential of olive oil secoiridoid phenols on humans performing intervention studies on populations at high cancer risk. PMID- 27713962 TI - Dietary supplement based on stilbenes: a focus on gut microbial metabolism by the in vitro simulator M-SHIME(r). AB - Polyphenols and intestinal microbiota can influence each other, modifying metabolism and gut wellness. Data on this mutual effect need to be improved. Several studies on the biological activities of resveratrol and derivatives have been carried out, but the effects of a continuous administration of stilbenes on gut microbiota have not yet been investigated. This study evaluated the effects of an extract from Vitis vinifera, containing a combination of t-resveratrol and epsilon-viniferin, on intestinal microbiota, using the advanced gastrointestinal simulator M-SHIME(r). A triple M-SHIME(r) experiment was performed using two concentrations of the extract (i.e. 1 and 2 g L-1), simulating a continuous daily intake. The effects were evaluated in terms of microbial functionality (SCFA and NH4+) and composition (DGGE and Illumina sequencing), since the microbiological aspect has been less considered so far. The treatment induced changes in microbial functionality and composition. In fact, the levels of SCFA and NH4+ suffered a strong decrease (i.e. inhibition of the saccharolytic and proteolytic activity), while DGGE and Illumina showed important modifications of the microbiota composition, associated with an imbalance of the colonic microbiota (i.e. increase in the relative abundance of Enterobacteriaceae). HPLC-DAD-TOF-MS analyses demonstrated that the metabolism of t-resveratrol and other stilbenes was inhibited by continuous administration. Our results suggest M-SHIME(r) as an explorative tool to define the dosage of food supplements, in particular to simulate effective continuous administration in humans. PMID- 27713963 TI - delta and gamma tocotrienols suppress human hepatocellular carcinoma cell proliferation via regulation of Ras-Raf-MEK-ERK pathway-associated upstream signaling. AB - Tocotrienol (T3) has recently gained increasing interest due to its anti-cancer effect. Here, we investigated the modulating effect of delta and gamma T3 on the Ras-Raf-MEK-ERK oncogenic upstream signaling pathway in human hepatocellular carcinoma HepG2 cells. The results indicated that T3 regulated the upstream signaling cascades of this pathway. PMID- 27713964 TI - Effect of consumption of a carob pod inositol-enriched beverage on insulin sensitivity and inflammation in middle-aged prediabetic subjects. AB - This study assessed the effects of an inositol-enriched beverage (IEB) on blood glucose levels and inflammation status in subjects with an impaired fasting glucose (IFG) state according to body mass index (BMI). This was a 12 week, double-blind, randomized, controlled trial employing forty-four IFG subjects (fasting glucose levels 100-125 mg dl-1) that were divided into two intervention groups: one receiving a IEB (n = 24) containing mainly pinitol (2.0 g twice a day), and the other a sweetened beverage based on sucrose (SB; n = 20). Anthropometric and biochemical measurements, postprandial and fasting nocturnal glycaemia (continuous glucose monitoring system), and inflammatory parameters (IL 6 and TNF-alpha) were analyzed at baseline and after intervention according to BMI (non-obese: BMI < 30 kg m-2 or obese: BMI >= 30 kg m-2). Non-obese subjects who consumed IEB exhibited a significant decrease in insulin (-14.4%), HOMA-IR index (-15.1%) and percentage of glucose change after postprandial and fasting nocturnal periods (-10.0% and -10.3%, respectively) compared with the SB group ( 2.35% and 10.2%, respectively) although they did not show any change in inflammatory cytokine levels. By contrast, obese subjects who consumed IEB showed a smaller variation in glucose levels after nocturnal fasting (-4.34%) and a marked decrease in IL-6 and TNF-alpha (p < 0.05). These findings support that consumption of IEB in prediabetic subjects produces a response that is dependent on BMI, with a clear improvement of insulin resistance and postprandial and nocturnal glycemia in non-obese subjects and a marked anti-inflammatory response in obese subjects. PMID- 27713966 TI - Hydroxysafflor yellow A inhibits IL-1beta-induced release of IL-6, IL-8, and MMP 1 via suppression of ERK, NF-kappaB and AP-1 signaling in SW982 human synovial cells. AB - Hydroxysafflor yellow A (HSYA), the main active ingredient in medical and edible dual purpose plant safflower, is reported to have multiple bioactivities. In the present study, the anti-inflammatory effects of HSYA and the underlying mechanisms were investigated in interleukin (IL)-1beta-induced SW982 human synovial cells. The cells were pretreated with HSYA at various concentrations (2.5, 10 and 40 MUM) followed by IL-1beta (10 ng mL-1) stimulation. HSYA significantly inhibited the expression of IL-6, IL-8 and matrix metalloproteinase (MMP)-1 in IL-1beta-stimulated SW982 cells. HSYA also inhibited the phosphorylation of extracellular signal-regulated kinase (ERK), p65 and c-Jun. It also suppressed the degradation of IkappaBalpha and blocked p65 translocation into the nucleus. These results indicate that the inhibitory effects of HSYA on IL-1beta-induced IL-6, IL-8 and MMP-1 release might be mediated via suppression of ERK, nuclear factor-kappaB (NF-kappaB) and activator protein-1 (AP-1) signaling pathways. The present data support the potential role of HSYA as an effective therapeutic agent in osteoarthritis. PMID- 27713967 TI - Cell-cycle-dependent Ca2+ transients in human induced pluripotent stem cells revealed by a simultaneous imaging of cell nuclei and intracellular Ca2+ level. AB - Cell cycle phase and [Ca2+]i are key determinants of self-renewal and differentiation in pluripotent stem cells. However, little is known about their relationship in human pluripotent stem cells owing to the lack of an effective method. Here, we applied an imaging-based approach for evaluating the relationship between the cell cycle and Ca2+ transients in human induced pluripotent stem (iPS) cells. Ca imaging and DNA staining was simultaneously performed at the same site. Then, individual cells were recognized and the cell cycle phase was estimated from the image of nuclei. We found that 18 +/- 4% of human iPS cells exhibited spontaneous Ca2+ transients and their inter-transient interval was 119 +/- 19 s. Ca wave events were observed in 64% of the sample and the [Ca2+]i elevation propagated among 47 +/- 30 cells with a duration of 57 +/- 22 s. With the imaging-based approach, we demonstrated that the ratio of cells exhibiting Ca2+ transients significantly decreased during cell cycle progression, suggesting that the relationship previously described in mouse cells holds true in the human context as well. These results suggest that our method is suitable for evaluating Ca2+ transients, the cell cycle phase, and their relationship with densely cultured cells.

AB - The measured metabolizable energy (ME) of whole almonds has been shown to be less than predicted by Atwater factors. However, data are lacking on the effects of processing (roasting, chopping or grinding) on the ME of almonds. A 5-period randomized, crossover study in healthy individuals (n = 18) was conducted to measure the ME of different forms of almonds (42 g per day), as part of a controlled diet: whole, natural almonds; whole, roasted almonds; chopped almonds; almond butter; and control (0 g per day). After 9 days of adaptation to each diet, participants collected all urine and fecal samples for 9 days. Diets, urine, and feces were analyzed to determine ME. Fracture force and fracture properties of whole and chopped almonds were measured. Measured ME (kcal g-1) of whole natural almonds (4.42), whole roasted almonds (4.86), and chopped almonds (5.04) was significantly lower than predicted with Atwater factors (P < 0.001); ME of almond butter (6.53 kcal g-1) was similar to predicted (P = 0.08). The ME of whole roasted and chopped almonds was lower than almond butter (P < 0.0001). ME of whole natural almonds was lower than whole roasted almonds (P < 0.05). This may be due to lower hardness of whole roasted (298 +/- 1.3 N) compared to whole natural almonds (345 +/- 1.6 N) (P < 0.05), and to whole natural almonds fracturing into fewer, larger particles, thus inhibiting the release of lipids. Atwater factors overestimate the ME of whole (natural and roasted) and chopped almonds. The amount of calories absorbed from almonds is dependent on the form in which they are consumed. PMID- 27713965 TI - Dietary resistant starch type 4-derived butyrate attenuates nuclear factor-kappa B1 through modulation of histone H3 trimethylation at lysine 27. AB - Indigestible resistant starches (RS) are substrates for gut-microbial metabolism and have been shown to attenuate intestinal inflammation but the supporting evidence is inconsistent and lacks mechanistic explanation. We have recently reported dietary RS type 4 (RS4) induced improvements in immunometabolic functions in humans and a concomitant increase in butyrogenic gut-bacteria. Since inflammation is a key component in metabolic diseases, here we investigated the effects of RS4-derived butyrate on the epigenetic repression of pro-inflammatory genes in vivo and in vitro. RS4-fed mice, compared to the control-diet group, had higher cecal butyrate and increased tri-methylation of lysine 27 on histone 3 (H3K27me3) in the promoter of nuclear factor-kappa-B1 (NFkappaB1) in the colon tissue. The H3K27me3-enrichment inversely correlated with the concentration dependent down-regulation of NFkappaB1 in sodium butyrate treated human colon epithelial cells. Two additional inflammatory genes were attenuated by sodium butyrate, but were not linked with H3K27me3 changes. This exploratory study presents a new opportunity for studying underlying H3K27me3 and other methylation modifying mechanisms linked to RS4 biological activity. PMID- 27713969 TI - Effect of Bactrocera oleae on phenolic compounds and antioxidant and antibacterial activities of two Algerian olive cultivars. AB - Bactrocera oleae, an olive fruit fly, is a major olive pest in Algeria. In this study, olives of two Algerian cultivars (Limli and Rougette de Metidja) with different degrees of infestation by the Bactrocera oleae fly (0%, not attacked; 100%, all attacked; and real %) were analysed. The influence of this pest on individual phenolic compounds (HPLC-DAD-FLD) and antioxidant profiles was ascertained. The antibacterial activity against 8 human enteropathogenic bacteria was also assessed. The results show that Rougette de Metidja, the cultivar with higher drupe size, was attacked to a greater degree than Limli, and the B. oleae attack caused a significant decrease in the total phenolic contents (>50%), including oleuropein, verbascoside, luteolin-7-O-glucoside, tyrosol and hydroxytyrosol. The antioxidant and antibacterial activities were highly correlated with the phenolic levels. Extracts from healthy olives were more effective against bacteria than those obtained from attacked olives. Globally, olive fly affected significantly the phenolic compounds of olives and their biological properties. PMID- 27713970 TI - Actomyosin contractility and RhoGTPases affect cell-polarity and directional migration during haptotaxis. AB - Although much is known about chemotaxis- induced by gradients of soluble chemical cues - the molecular mechanisms involved in haptotaxis (migration induced by substrate-bound protein gradients) are largely unknown. We used micropatterning to produce discontinuous gradients consisting of MUm-sized fibronectin-dots arranged at constant lateral but continuously decreasing axial spacing. Parameters like gradient slope, protein concentration and size or shape of the fibronectin dots were modified to determine optimal conditions for directional cell migration in gradient patterns. We demonstrate that fibroblasts predominantly migrate uphill towards a higher fibronectin density in gradients with a dot size of 2 * 2 MUm, a 2% and 6% slope, and a low fibronectin concentration of 1 MUg ml-1. Increasing dot size to 3.5 * 3.5 MUm resulted in stationary cells, whereas rectangular dots (2 * 3 MUm) orientated perpendicular to the gradient axis preferentially induce lateral migration. During haptotaxis, the Golgi apparatus reorients to a posterior position between the nucleus and the trailing edge. Using pharmacological inhibitors, we demonstrate that actomyosin contractility and microtubule dynamics are a prerequisite for gradient recognition indicating that asymmetric intracellular forces are necessary to read the axis of adhesive gradients. In the haptotaxis signalling cascade, RhoA and Cdc42, and the atypical protein kinase C zeta (aPKCzeta), but not Rac, are located upstream of actomyosin contractility. PMID- 27713971 TI - Template-assisted extrusion of biopolymer nanofibers under physiological conditions. AB - Biomedical applications ranging from tissue engineering to drug delivery systems require versatile biomaterials based on the scalable and tunable production of biopolymer nanofibers under physiological conditions. These requirements can be successfully met by a novel extrusion process through nanoporous aluminum oxide templates, which is presented in this study. With this simple method we are able to control the nanofiber diameter by chosing the size of the nanopores and the concentration of the biopolymer feed solution. Nanofiber assembly into different hierarchical fiber arrangements can be achieved with a wide variety of different proteins ranging from the intracellular proteins actin, alpha-actinin and myosin to the extracellular matrix components collagen, fibronectin, fibrinogen, elastin and laminin. The extrusion of nanofibers can even be applied to the polysaccharides hyaluronan, chitosan and chondroitin sulphate. Moreover, blends of different proteins or proteins and polysaccharides can be extruded into composite nanofibers. With these features our template-assisted extrusion process will lead to new avenues in the development of nanofibrous biomaterials.

AB - The effects of chronic administration of piceatannol-enriched (9.5% w/w) passion fruit seed extract (PFSE) on the cardiovascular damage induced in a high-fat (HF) diet-fed model of Fischer 344 rats were evaluated. Rats were fed the control, HF, or HF diets containing PFSE (0.5% w/w) for 16 weeks, and the effects of the various diets on the tissue weight, serum lipid profile, hepatic fibrosis, hepatic ductular reaction, cardiac function and aortic ring reactivity were examined. HF diet-fed rats developed signs of cardiovascular disease with abnormal serum profiles compared to control diet-fed rats. PFSE supplementation improved the liver hypertrophy and hepatic histology of the HF diet-fed rats. In addition, the triglyceride and cholesterol levels, platelet aggregation, cardiac function, and acetylcholine-mediated relaxation of the aortic ring were improved. These results suggest that the chronic intake of PFSE containing piceatannol prevents HF diet-induced cardiovascular disease in rats. PMID- 27713973 TI - Effects of enzyme activities during steeping and sprouting on the solubility and composition of proteins, their bioactivity and relationship with the bread making quality of wheat flour. AB - The aim was to determine the effect of steeping and sprouting on wheat grain proteins and the functional consequences in this regard. The solubility of proteins and the polypeptide composition of albumins, globulins, gliadins and glutenins were determined, as well as the content of non-protein nitrogen and free sulfhydryl groups (-SH), and the activity of peroxidase (POD) and lipoxygenase (LOX). In addition, the pasting viscosity of flour and protein bioactivity such as antioxidant capacity and immunoreactivity were evaluated. The increase of non-protein nitrogen and free -SH groups by about 62.09 and 96.7%, respectively, as well as the decrease of albumin + globulin polypeptides with a molecular weight over 85.94 kDa and between 85.94-48.00 kDa by about 34 and 8.7%, respectively, were the most notable changes observed in the flour from whole sprouted wheat that clearly point to the intensive protein hydrolysis. The reduction of disulfide bonds and increased concentrations of free -SH groups significantly modify the visco-elastic properties of gliadins and glutenins causing pasting viscosity reduction. However, sprouted wheat flour could be considered as a potential food ingredient because of its improved antioxidant capacity that is a result of protein hydrolysis inter alia. As protein modification induced by steeping may have beneficial effects on the antigenicity of the glutenin fraction, this kind of wheat pretreatment can represent a putative strategy in the dietary modulation of diseases related to glutenin immunoreactivity, e.g. dermatitis herpetiformis.

AB - Modulation of the human gut microbiota has proven to have beneficial effects on host health. The aim of this work was to evaluate the effect of sun-dried raisins (SR) on the composition of the human gut microbiota. A full model of the gastrointestinal tract, which includes simulated mastication, a dynamic gastric model, a duodenal model and a colonic model of the human large intestine, was used. An increase in the numbers of bifidobacteria and lactobacilli was observed by plate-counting in response to the addition of either SR or FOS after 8 and 24 h fermentation. A significant decrease in Firmicutes and Bacteroidetes was observed in SR samples after 8 and 24 h fermentation. FOS resulted in the greatest production of short chain fatty acids. Sun-dried raisins demonstrated considerable potential to promote the colonization and proliferation of beneficial bacteria in the human large intestine and to stimulate the production of organic acids. PMID- 27713976 TI - Microfluidic partition with in situ biofabricated semipermeable biopolymer membranes for static gradient generation. AB - We report an in situ biofabrication strategy that conveniently partitions microfluidic networks into physically separated while chemically communicating microchannels with semipermeable biopolymer membranes, which enable the facile generation of static gradients for biomedical applications. The biofabrication of parallel biopolymer membranes was initiated with the dissipation of trapped air bubbles in parallel apertures in polydimethylsiloxane (PDMS) microfluidic devices, followed by tunable membrane growth with precise temporal and spatial control to the desired thickness. Static gradients were generated within minutes and well maintained over time by pure diffusion of molecules through the biofabricated semipermeable membranes. As an example application, the static gradient of alpha factor was generated to study the development of the "shmoo" morphology of yeast over time. The in situ biofabrication provides a simple approach to generate static gradients and an ideal platform for biological applications where flow-free static gradients are indispensable. PMID- 27713977 TI - Microfluidic technique for measuring wax appearance temperature of reservoir fluids. AB - A microfluidic technique for measuring wax appearance temperature (WAT) of reservoir fluids is presented. The technique is based on continuous monitoring of pressure across a microchannel as wax particles are deposited and gradually clog the channel. A rapid pressure increase was observed as the temperature was systematically decreased to wax appearance temperature. The relationship between pressure change rate and sample temperature is explored as the working principle in the proposed WAT measurement technique. This technique yields results which are comparable to measurements obtained from a cross-polar microscopy technique (CPM); the current industry-standard for WAT measurement. The method is validated by systematically investigating phase transition of pure hydrocarbons, binary mixtures, and real crude oils. The new technique has two distinct advantages over the existing industry standard methods in that its experimental setup is much simpler and it can be adapted to field applications. The microchannel can be easily cleaned and reused to test different samples. PMID- 27713975 TI - Modeling of the mechano-chemical behaviour of the nuclear pore complex: current research and perspectives. AB - Recent evidence suggests that mechanical deformation of the cell nucleus regulates the nuclear import of the transcriptional activators of genes involved in primary physiological cell responses such as stem cell differentiation. In addition, this nuclear mechanosensing response is de-regulated in pathological states, such as cancer and neurodegeneration. One hypothesis that could greatly advance the field is that the deformation of the nuclear envelope activates nuclear pore complexes through a direct mechanical link. The understanding of this possible mechanism for nuclear pore complex stretch-activation entails studying the mechanical connection of this complex to the nuclear envelope at the nanoscale. The nanomechanics of the nuclear pore complex is thus emerging as a novel research field, bridging nanoscience with nanotechnology. This review examines the frontier of research methodologies that are potentially useful for building a computational model of this interaction. This includes, for example, electron tomography to assess the geometrical features of the nuclear pore complex and nanoindentation to estimate its mechanical properties and that of the nuclear envelope. In order to summarize the state-of-the-art and perspectives in the field of NPC nanomechanics, this review covers highly interdisciplinary experimental and theoretical research methodologies pertaining to the fields of physics, chemistry, biology, materials and mechanics. PMID- 27713978 TI - Random design of microfluidics. AB - In this work we created functional microfluidic chips without actually designing them. We accomplished this by first generating a library of thousands of different random microfluidic chip designs, then simulating the behavior of each design on a computer using automated finite element analysis. The simulation results were then saved to a database which a user can query via to find chip designs suitable for a specific task. To demonstrate this functionality, we used our library to select chip designs that generate any three desired concentrations of a solute. We also fabricated and tested 16 chips from the library, confirmed that they function as predicted, and used these chips to perform a cell growth rate assay. This is one of many different applications for randomly-designed microfluidics; in principle, any microfluidic chip that can be simulated could be designed automatically using our method. Using this approach, individuals with no training in microfluidics can obtain custom chip designs for their own unique needs in just a few seconds. PMID- 27713979 TI - Magnetic separation of acoustically focused cancer cells from blood for magnetographic templating and analysis. AB - Liquid biopsies hold enormous promise for the next generation of medical diagnoses. At the forefront of this effort, many are seeking to capture, enumerate and analyze circulating tumor cells (CTCs) as a means to prognosticate and develop individualized treatments for cancer. Capturing these rare cells, however, represents a major engineering challenge due to their low abundance, morphology and heterogeneity. A variety of microfluidic tools have been developed to isolate CTCs from drawn blood samples; however, few of these approaches offer a means to separate and analyze cells in an integrated system. We have developed a microfluidic platform comprised of three modules that offers high throughput separation of cancer cells from blood and on-chip organization of those cells for streamlined analyses. The first module uses an acoustic standing wave to rapidly align cells in a contact-free manner. The second module then separates magnetically labeled cells from unlabeled cells, offering purities exceeding 85% for cells and 90% for binary mixtures of synthetic particles. Finally, the third module contains a spatially periodic array of microwells with underlying micromagnets to capture individual cells for on-chip analyses (e.g., staining, imaging and quantification). This array is capable of capturing with accuracies exceeding 80% for magnetically labeled cells and 95% for magnetic particles. Overall, by virtue of its holistic processing of complex biological samples, this system has promise for the isolation and evaluation of rare cancer cells and can be readily extended to address a variety of applications across single cell biology and immunology. PMID- 27713980 TI - Additively manufactured MEMS multiplexed coaxial electrospray sources for high throughput, uniform generation of core-shell microparticles. AB - This study reports the first MEMS multiplexed coaxial electrospray sources in the literature. Coaxial electrospraying is a microencapsulation technology based on electrohydrodynamic jetting of two immiscible liquids, which allows precise control with low size variation of the geometry of the core-shell particles it generates, which is of great importance in numerous biomedical and engineering applications, e.g., drug delivery and self-healing composites. By implementing monolithic planar arrays of miniaturized coaxial electrospray emitters that work uniformly in parallel, the throughput of the compound microdroplet source is greatly increased, making the microencapsulation technology compatible with low cost commercial applications. Miniaturized core-shell particle generators with up to 25 coaxial electrospray emitters (25 emitters cm-2) were fabricated via stereolithography, which is an additive manufacturing process that can create complex microfluidic devices at a small fraction of the cost per device and fabrication time associated with silicon-based counterparts. The characterization of devices with the same emitter structure but different array sizes demonstrates uniform array operation. Moreover, the data demonstrate that the per-emitter current is approximately proportional to the square root of the flow rate of the driving liquid, and it is independent of the flow rate of the driven liquid, as predicted by the theory. The core/shell diameters and the size distribution of the generated compound microparticles can be modulated by controlling the flow rates fed to the emitters. PMID- 27713981 TI - Field effect nanofluidics. AB - Nanoscale fluid transport through conduits in the 1-100 nm range is termed as nanofluidics. Over the past decade or so, significant scientific and technological advances have occurred in the domain of nanofluidics with a transverse external electrical signal through a dielectric layer permitting control over ionic and fluid flows in these nanoscale conduits. Consequently, this special class of nanofluidic devices is commonly referred to as field effect devices, analogous to the solid-state field effect transistors that form the basis for modern electronics. In this mini-review, we focus on summarizing the recent developments in field effect nanofluidics as a discipline and evaluate both tutorially and critically the scientific and technological advances that have been reported, including a discussion on the future outlook and identifying broad open questions which suggest that there are many breakthroughs still to come in field-effect nanofluidics. PMID- 27713982 TI - Smart hydrogels as storage elements with dispensing functionality in discontinuous microfluidic systems. AB - Smart hydrogels are useful elements in microfluidic systems because they respond to environmental stimuli and are capable of storing reagents. We present here a concept of using hydrogels (poly(N-isopropylacrylamide)) as an interface between continuous and discontinuous microfluidics. Their swelling and shrinking capabilities allow them to act as storage elements for reagents absorbed in the swelling process. When the swollen hydrogel collapses in an oil-filled channel, the incorporated water and molecules are expelled from the hydrogel and form a water reservoir. Water-in-oil droplets can be released from the reservoir generating different sized droplets depending on the flow regime at various oil flow rates (dispensing functionality). Different hydrogel sizes and microfluidic structures are discussed in terms of their storage and droplet formation capabilities. The time behaviour of the hydrogel element is investigated by dynamic swelling experiments and computational fluid dynamics simulations. By precise temperature control, the device acts as an active droplet generator and converts continuous to discontinuous flows. PMID- 27713983 TI - Scanning-SAXS of microfluidic flows: nanostructural mapping of soft matter. AB - The determination of in situ structural information of soft matter under flow is challenging, as it depends on many factors, such as temperature, concentration, confinement, channel geometry, and type of imposed flow. Here, we combine microfluidics and scanning small-angle X-ray scattering (scanning-SAXS) to create a two-dimensional spatially resolved map, which represents quantitatively the variation of molecular properties under flow. As application examples, mappings of confined amyloid fibrils and wormlike micelles under flow into various channel geometries are compared. A simple process to fabricate X-rays resistant chips, based on polyimide and UV-curing resin, is discussed. During experiments, these chips remained in high-energy synchrotron radiation for more than 24 hours, causing constant low background scattering. Thus, sufficient statistics were obtained from sample scattering at exposure times as low as 0.1 s, even with the small scattering volumes in microfluidic channels. Scanning-SAXS of microfluidic flows has many potential applications from biology to fundamental soft matter physics. In general, any fluid which has enough contrast for X-ray scattering can be measured to obtain the dependence of molecular shape, conformation, alignment and size on the flow field. Besides, dynamic processes of soft matter caused by flow, temperature, concentration gradient, and confinement, for example self assembling, aggregation, mixing, diffusion, and disintegration of macromolecules, can be quantified and visualized on a single image by this mapping technique. PMID- 27713985 TI - Fully automated chemiluminescence detection using an electrified-Lab-on-a-Disc (eLoaD) platform. AB - Typical Lab-on-a-Disc (LoaD) platforms cannot make a continuous measurement while the disc is spinning; this drawback means that the disc usually must be stopped and aligned with a sensor. This can result in measurement errors in time dependent assays along with inaccuracies due to liquid displacement and bubble formation in the absence of a stabilising centrifugal field. This paper presents a novel concept for a wirelessly electrified-Lab-on-a-Disc (eLoaD) platform that allows continuous measurement of experimental parameters while the disc is spinning. This platform incorporates all the components needed for measurement within the rotating frame of reference, and bidirectional transmission of data outside this reference frame, thus allowing for online measurement independent of the rotation of the disc. The eLoaD platform is conceived in a modular manner whereby an interchangeable and non-disposable 'Application Disc' can be fitted to the eLoaD platform and so the system can be adapted for a range of optical, electrochemical and other measurement types. As an application example, optical readout, using the Application Disc fitted with a silicon photomultiplier, is demonstrated using a tagged chemiluminescent antibody, which is commonly used, for instance, in ELISA assays. The precision of the eLoaD platform is >94%, while its accuracy, when compared to a commercial benchtop luminometer, is higher than 96%. The modular design of this platform will permit extension of this technology to many other LoaD applications. PMID- 27713984 TI - Heracleum orphanidis: chemical characterisation, and comparative evaluation of antioxidant and antimicrobial activities with specific interest in the influence on Pseudomonas aeruginosa PAO1. AB - GC-FID and GC-MS were used to determine the chemical composition of the essential oil of the aerial parts of Heracleum orphanidis Boiss. Also, the HPLC-DAD/ESI-ToF MS profile of the methanol extracts of aerial parts and roots was determined. The main components of the essential oil were n-octanol, octyl hexanoate and n-octyl acetate, while coumarins were the most prevalent compounds in methanol extracts. An evaluation of antioxidant activity showed that the methanol and aqueous extracts of the aerial parts had the highest potential. In terms of antimicrobial activity determined by microdilution assays, the essential oil and methanol extract of the roots showed the greatest effectiveness. The colonies of Pseudomonas aeruginosa PAO1 treated with H. orphanidis samples produced less toxic pyocyanin, showed lower twitching and flagella mobility and biofilm formatting was reduced. The analyses in this study showed the considerable biological potential of H. orphanidis considering free radicals and various pathogenic strains, including the wild type of P. aeruginosa. PMID- 27713986 TI - Micro-/nanoscale electroporation. AB - Electroporation has been one of the most popular non-viral technologies for cell transfection. However, conventional bulk electroporation (BEP) shows significant limitations in efficiency, cell viability and transfection uniformity. Recent advances in microscale-electroporation (MEP) resulted in improved cell viability. Further miniaturization of the electroporation system (i.e., nanoscale) has brought up many unique advantages, including negligible cell damage and dosage control capabilities with single-cell resolution, which has enabled more translational applications. In this review, we give an insight into the fundamental and technical aspects of micro- and nanoscale/nanochannel electroporation (NEP) and go over several examples of MEP/NEP-based cutting-edge research, including gene editing, adoptive immunotherapy, and cellular reprogramming. The challenges and opportunities of advanced electroporation technologies are also discussed. PMID- 27713988 TI - Magnetic-adhesive based valves for microfluidic devices used in low-resource settings. AB - Since the introduction of micro total analytical systems (MUTASs), significant advances have been made toward development of lab-on-a-chip platforms capable of performing complex biological assays that can revolutionize public health, among other applications. However, use of these platforms in low-resource environments (e.g. developing countries) has yet to be realized as the majority of technologies used to control microfluidic flow rely on off-device hardware with non-negligible size, cost, power requirements and skill/training to operate. In this paper we describe a magnetic-adhesive based valve that is simple to construct and operate, and can be used to control fluid flow and store reagents within a microfluidic device. The design consists of a port connecting two chambers on different planes in the device that is closed by a neodymium disk magnet seated on a thin ring of adhesive. Bringing an external magnet into contact with the outer surface of the device unseats and displaces the valve magnet from the adhesive ring, exposing the port. Using this configuration, we demonstrate on-device reagent storage and on-demand transport and reaction of contents between chambers. This design requires no power or external instrumentation to operate, is extremely low cost ($0.20 materials cost per valve), can be used by individuals with no technical training, and requires only a hand-held magnet to actuate. Additionally, valve actuation does not compromise the integrity of the completely sealed microfluidic device, increasing safety for the operator when toxic or harmful substances are contained within. This valve concept has the potential to simplify design of MUTASs, facilitating development of lab-on-a-chip systems that may be practical for use in point-of-care and low resource settings. PMID- 27713987 TI - Rapid, portable and cost-effective yeast cell viability and concentration analysis using lensfree on-chip microscopy and machine learning. AB - Monitoring yeast cell viability and concentration is important in brewing, baking and biofuel production. However, existing methods of measuring viability and concentration are relatively bulky, tedious and expensive. Here we demonstrate a compact and cost-effective automatic yeast analysis platform (AYAP), which can rapidly measure cell concentration and viability. AYAP is based on digital in line holography and on-chip microscopy and rapidly images a large field-of-view of 22.5 mm2. This lens-free microscope weighs 70 g and utilizes a partially coherent illumination source and an opto-electronic image sensor chip. A touch screen user interface based on a tablet-PC is developed to reconstruct the holographic shadows captured by the image sensor chip and use a support vector machine (SVM) model to automatically classify live and dead cells in a yeast sample stained with methylene blue. In order to quantify its accuracy, we varied the viability and concentration of the cells and compared AYAP's performance with a fluorescence exclusion staining based gold-standard using regression analysis. The results agree very well with this gold-standard method and no significant difference was observed between the two methods within a concentration range of 1.4 * 105 to 1.4 * 106 cells per mL, providing a dynamic range suitable for various applications. This lensfree computational imaging technology that is coupled with machine learning algorithms would be useful for cost-effective and rapid quantification of cell viability and density even in field and resource poor settings. PMID- 27713989 TI - Assessment of the prebiotic effect of quinoa and amaranth in the human intestinal ecosystem. AB - Quinoa and amaranth belong to the group of the so called "superfoods" and have a nutritional composition that confers multiple benefits. In this work, we explored the possibility of these foods exhibiting a prebiotic effect. These pseudocereals were subjected to an in vitro digestion and used as carbon sources in batch cultures with faecal human inocula. The effects on the microbiota composition and their metabolic products were determined by assessment of variations in pH, short chain fatty acid (SCFA) production and changes in the dynamic bacterial populations by fluorescence in situ hybridization (FISH). After 48 h of incubation, the total SCFAs were 106.5 mM for quinoa and 108.83 mM for amaranth, in line with the decrease in pH. Considerable differences (p < 0.05) were found in certain microbial groups, including Bifidobacterium spp., Lactobacillus Enterococcus, Atopobium, Bacteroides-Prevotella, Clostridium coccoides Eubacterium rectale, Faecalibacterium prausnitzii and Roseburia intestinalis. Our research suggests that these pseudocereals can have the prebiotic potential and that their intake may improve dysbiosis or maintain the gastrointestinal health through a balanced intestinal microbiota, although additional studies are necessary. PMID- 27713990 TI - Intake of cookies made with buriti oil (Mauritia flexuosa) improves vitamin A status and lipid profiles in young rats. AB - The oil extracted from Mauritia flexuosa (buriti) is rich in vitamin A, tocopherols and unsaturated fatty acids. This study evaluated the retinol status, blood glucose levels, lipid profiles, food efficiency rates (FERs), food conversion rates (FCRs) and murine anthropometric parameters of Wistar rats fed cookies made with buriti oil (BOC). The content of beta-carotene and monounsaturated fatty acids in the cookies was enhanced (p < 0.05) using buriti oil. Rats fed BOC showed an increase (p < 0.05) in serum and hepatic retinol levels compared to rats fed cookies made with soy oil (SOC - control). Rats fed BOC showed lower (p < 0.05) total and LDL cholesterol than the control; however, no changes in blood glucose levels or murine anthropometric parameters were observed. Serum retinol contents showed a strong correlation (r > 0.8) with hepatic retinol, and both groups of rats showed moderate correlations (r > 0.6 < 0.5) with FERs, FCRs and weight gain. Taken together, these results indicated that buriti is an alternative to increase vitamin A in baked goods, particularly in cookies. Intake of BOC improves lipid profiles and retinol status without affecting blood glucose in young rats. PMID- 27713991 TI - CMOS biosensors for in vitro diagnosis - transducing mechanisms and applications. AB - Complementary metal oxide semiconductor (CMOS) technology enables low-cost and large-scale integration of transistors and physical sensing materials on tiny chips (e.g., <1 cm2), seamlessly combining the two key functions of biosensors: transducing and signal processing. Recent CMOS biosensors unified different transducing mechanisms (impedance, fluorescence, and nuclear spin) and readout electronics have demonstrated competitive sensitivity for in vitro diagnosis, such as detection of DNA (down to 10 aM), protein (down to 10 fM), or bacteria/cells (single cell). Herein, we detail the recent advances in CMOS biosensors, centering on their key principles, requisites, and applications. Together, these may contribute to the advancement of our healthcare system, which should be decentralized by broadly utilizing point-of-care diagnostic tools. PMID- 27713992 TI - In vitro bioaccessibility, transepithelial transport and antioxidant activity of Urtica dioica L. phenolic compounds in nettle based food products. AB - Nettle (Urtica dioica L.) is a well-known plant with a wide historical background use of stems, roots and leaves. Nettle leaves are an excellent source of phenolic compounds, principally 3-caffeoylquinic acid (3-CQA), caffeoylmalic acid (CMA) and rutin. The aim of this work was to evaluate the bioaccessibility (BAC), the bioavailability (BAV) and the antioxidant activity of nettle phenolic compounds present in foods and supplements. The BAC of nettle phenolics was evaluated with an in vitro dynamic digestion of real food matrices: the type of food matrix and chemical characteristic affected the kinetics of release and solubilization, with the highest BAC after duodenal digestion. A study of duodenal trans epithelial transport evidenced low bioavailability of native forms of 3-CQA, CMA and rutin. Simulation of colonic metabolism confirmed that phenolic compounds are fermented by gut microflora, confirming the need for further investigations on the impact of phenolic compounds at the large intestine level. Photochemiluminescence assay of the simulated digestion fluids demonstrated that ingestion of Urtica based foods contributes to create an antioxidant environment against superoxide anion radicals in the entire gastrointestinal tract (GIT). PMID- 27713993 TI - Polymerase chain reaction in microfluidic devices. AB - The invention of the polymerase chain reaction (PCR) has caused a revolution in molecular biology, giving access to a method of amplifying deoxyribonucleic acid (DNA) molecules across several orders of magnitude. Since the first application of PCR in a microfluidic device was developed in 1998, an increasing number of researchers have continued the development of microfluidic PCR systems. In this review, we introduce recent developments in microfluidic-based space and time domain devices as well as discuss various designs integrated with multiple functions for sample preparation and detection. The development of isothermal nucleic acid amplification and digital PCR microfluidic devices within the last five years is also highlighted. Furthermore, we introduce various commercial microfluidic PCR devices. PMID- 27713995 TI - Dynamics of bacterial streamers induced clogging in microfluidic devices. AB - Using a microfabricated porous media mimic platform, we investigated the clogging dynamics of bacterial biomass that accumulated in the device due to the formation of bacterial streamers. Particularly, we found the existence of a distinct clogging front which advanced via pronounced 'stick-slip' of the viscoelastic bacterial biomass over the solid surface of the micro pillar. Thus, the streamer, the solid surface, and the background fluidic media defined a clear three-phase front influencing these advancing dynamics. Interestingly, we also found that once the clogging became substantial, contrary to a static homogenous saturation state, the clogged mimic exhibited an instability phenomena marked by localized streamer breakage and failure leading to extended water channels throughout the mimic. These findings have implications for design and fabrication of biomedical devices and membrane-type systems such as porous balloon catheters, porous stents and filtration membranes prone to bacteria induced clogging as well as understanding bacterial growth and proliferation in natural porous media such as soil and rocks. PMID- 27713994 TI - Screw-actuated displacement micropumps for thermoplastic microfluidics. AB - The fabrication of on-chip displacement pumps integrated into thermoplastic chips is explored as a simple and low cost method for achieving precise and programmable flow control for disposable microfluidic systems. The displacement pumps consist of stainless steel screws inserted into threaded ports machined into a thermoplastic substrate which also serve as on-chip reagent storage reservoirs. Three different methods for pump sealing are investigated to enable high pressure flows without leakage, and software-defined control of multiple pumps is demonstrated in a self-contained platform using a compact and self contained microcontroller for operation. Using this system, flow rates ranging from 0.5-40 MUl min-1 are demonstrated. The pumps are combined with on-chip burst valves to fully seal multiple reagents into fabricated chips while providing on demand fluid distribution in a downstream microfluidic network, and demonstrated for the generation of size-tunable water-in-oil emulsions. PMID- 27713996 TI - Emergence of microfluidic wearable technologies. AB - There has been an intense interest in the development of wearable technologies, arising from increasing demands in the areas of fitness and healthcare. While still at an early stage, incorporating microfluidics in wearable technologies has enormous potential, especially in healthcare applications. For example, current microfluidic fabrication techniques can be innovatively modified to fabricate microstructures and incorporate electrically conductive elements on soft, flexible and stretchable materials. In fact, by leverarging on such microfabrication and liquid manipulation techniques, the developed flexible microfluidic wearable technologies have enabled several biosensing applications, including in situ sweat metabolites analysis, vital signs monitoring, and gait analysis. As such, we anticipate further significant breakthroughs and potential uses of wearable microfluidics in active drug delivery patches, soft robotics sensing and control, and even implantable artificial organs in the near future. PMID- 27713998 TI - Diagnosis of iron deficiency anemia using density-based fractionation of red blood cells. AB - Iron deficiency anemia (IDA) is a nutritional disorder that impacts over one billion people worldwide; it may cause permanent cognitive impairment in children, fatigue in adults, and suboptimal outcomes in pregnancy. IDA can be diagnosed by detection of red blood cells (RBCs) that are characteristically small (microcytic) and deficient in hemoglobin (hypochromic), typically by examining the results of a complete blood count performed by a hematology analyzer. These instruments are expensive, not portable, and require trained personnel; they are, therefore, unavailable in many low-resource settings. This paper describes a low-cost and rapid method to diagnose IDA using aqueous multiphase systems (AMPS)-thermodynamically stable mixtures of biocompatible polymers and salt that spontaneously form discrete layers having sharp steps in density. AMPS are preloaded into a microhematocrit tube and used with a drop of blood from a fingerstick. After only two minutes in a low-cost centrifuge, the tests (n = 152) were read by eye with a sensitivity of 84% (72-93%) and a specificity of 78% (68-86%), corresponding to an area under the curve (AUC) of 0.89. The AMPS test outperforms diagnosis by hemoglobin alone (AUC = 0.73) and is comparable to methods used in clinics like reticulocyte hemoglobin concentration (AUC = 0.91). Standard machine learning tools were used to analyze images of the resulting tests captured by a standard desktop scanner to 1) slightly improve diagnosis of IDA-sensitivity of 90% (83-96%) and a specificity of 77% (64-87%), and 2) predict several important red blood cell parameters, such as mean corpuscular hemoglobin concentration. These results suggest that the use of AMPS combined with machine learning provides an approach to developing point-of-care hematology. PMID- 27713997 TI - Valve interstitial cell contractile strength and metabolic state are dependent on its shape. AB - The role of valvular interstitial cell (VIC) architecture in regulating cardiac valve function and pathology is not well understood. VICs are known to be more elongated in a hypertensive environment compared to those in a normotensive environment. We have previously reported that valve tissues cultured under hypertensive conditions are prone to acute pathological alterations in cell phenotype and contractility. We therefore aimed to rigorously study the relationship between VIC shape, contractile output and other functional indicators of VIC pathology. We developed an in vitro model to engineer VICs to take on the same shapes as those seen in normal and hypertensive conditions. VICs with longer cellular and nuclear shapes, as seen in hypertensive conditions, had greater contractile response to endothelin-1 that correlated with increased anisotropy of the actin architecture. These elongated VICs also demonstrated altered cell metabolism through a decreased optical redox ratio, which coincided with increased cellular proliferation. In the presence of actin polymerization inhibitor, however, these functional responses were significantly reduced, suggesting the important role of cytoskeletal actin organization in regulating cellular responses to abnormal shape. Overall, these results demonstrate the relationship between cell shape, cytoskeletal and nuclear organization, with functional output including contractility, metabolism, and proliferation. PMID- 27713999 TI - An LC-MS based untargeted metabolomics study identified novel biomarkers for coronary heart disease. AB - This study performed untargeted metabolomics for plasma samples from 40 coronary heart disease patients and 43 healthy controls by high-performance liquid chromatography coupled with mass spectrometry technology to find a set of effective biomarkers for CHD diagnosis and prognosis. The discriminating metabolites were extracted and analyzed by univariate and multivariate analysis methods. We found five metabolites (1-naphthol, 2-naphthol, methylitaconate, N acetyl-d-glucosamine 6-phosphate and l-carnitine) contributing to the separation of CHD patients from healthy controls, and a subset of two metabolites in these five were identified as potential plasma biomarkers for CHD diagnosis. Major metabolic pathways associated with these potential biomarkers included nicotinate and nicotinamide metabolism, protein glycosylation, lipid metabolism and fatty acid metabolism. In addition, two potential biomarkers (GlcNAc-6-P and l carnitine) were found be to be associated with intestinal microflora, indicating that intestinal microflora may be related to the metabolism and progression of CHD. PMID- 27714000 TI - Flow-induced phase inversion of emulsions in tapered microchannels. AB - Phase inversion emulsification (PIE) is a process of generating emulsions by inverting the continuous and dispersed phases of pre-existing emulsions. Although PIE is conventionally performed in batch processes, flowing emulsions through precisely engineered channels (i.e. flow-induced phase inversion emulsification (FIPIE)) can induce PIE and potentially enable continuous processing. In this study, we demonstrate flow-induced phase inversion of oil-in-water (O/W) emulsions using microfluidic channels with gradual constriction. We investigate the importance of wetting properties and geometric characteristics of microfluidic channels on FIPIE. We show that two dimensionless groups, Ca and the ratio of droplet-size to channel dimensions determine the outcome of the process. In situ observation of individual droplets undergoing FIPIE reveals that the rupture of films of the continuous (water) phase between oil droplets and a wetting oil layer on the surface of microchannels is the most crucial step for phase inversion. Finally, we compare our experimental observations with a scaling relationship that is based on the force balance between disjoining pressure and Laplace pressure, which provides insights into the underlying physical phenomena responsible for the rupture of the aqueous film and the occurrence of FIPIE. We believe our work provides critical insights and parameters for designing channels and pores that can be used for continuous PIE. PMID- 27714001 TI - Single-layer microfluidic device to realize hydrodynamic 3D flow focusing. AB - The recent rapid growth of microfluidic applications has witnessed the emergence of several particle flow focusing techniques for analysis and/or further processing. The majority of flow focusing techniques employ an external sheath fluid to achieve sample flow focusing independent of the flow rate, in contrast to sheath-free techniques. However, the introduction of a sheath fluid to surround the sample fluid has complicated the device design and fabrication, generally involving multi-layer fabrication and bonding of multiple polydimethylsiloxane (PDMS) layers. Several promising efforts have been made to reduce the complexity of fabrication. However, most of these methods involved the use of inertial/Dean effects, which in turn demanded the use of higher sample flow rates. In this paper, we report a method of flow focusing that uses a sheath fluid to enclose the sample in a single layer of PDMS, and that possesses applicability for a wide range of sample flow rates. This method of flow focusing uses abrupt channel depth variation and a shift of one of the sample-sheath junctions (termed as 'junction-shift') against the direction of the sample flow. This configuration serves to manipulate the sample fluid with respect to the sheath fluid and achieve the desired flow focusing. This design facilitates the attainment of 3D flow focusing in two sequential steps (depth-wise and then along the lateral direction) and in distinct regions, hence enabling the regions to be used in imaging and non-imaging flow cytometric applications, respectively. Simulations were performed to characterize and determine the optimum set of design parameters. Experimental demonstrations of this technique were carried out by focusing fluorescein dye and blood cells in flow.

AB - Aiming at investigating the potential effect of minimal dietary changes in NAFLD patients with non-significant fibrosis, 55 patients with NAFLD were enrolled in a randomized controlled clinical trial. Patients were assigned into two isocaloric dietary treatment groups for 24 weeks: (a) nutritional counseling (Control arm, N = 27), (b) nutritional counseling with currants included (two fruit servings, 36 g per day), substituting snacks of similar caloric content (Currant arm, N = 28). Clinical tests, anthropometrics, inflammatory and oxidative stress markers were conducted pre- and post-intervention. A total of 50 patients completed the trial. Significant differences between the two arms post-intervention were observed in fasting glucose and in IL-6 levels, these being significantly decreased only in Currant patients. Body weight, BMI, HbA1c, CRP and EUS values decreased in both arms, differences being insignificant between the two arms post-intervention. Participants in the Currant arm had significantly reduced total body fat, WC and trunk fat. Ultrasound scanning improved significantly in patients snacking currants daily. Also, volunteers enrolled in the Currant arm showed a reduced intake of saturated fatty acids. Because BW regulation has been officially recognised as a treatment approach in NAFLD an additional analysis was repeated in patients adhering to this. Post-intervention, the decrease in IL-6 and in fasting glucose was significantly higher in Currant patients who lost BW compared to their counterparts in the Control arm. Conclusively, minimal modifications in snacking choices, such as the inclusion of dried grapes in diet, are beneficial in NAFLD patients with non-significant fibrosis.

AB - The construction of a micro-platform capable of microscale control for continuous, dynamic, and high-throughput biomimetic tumor manipulation and analysis plays a significant role in biological and clinical research. Here, we introduce a pneumatic microstructure-based microfluidic platform for versatile three-dimensional (3D) tumor cultures. The manipulative potential of pneumatic microstructures in a fabrication-optimized microfluidic device can be stimulated to achieve ultra-repetitive (tens of thousands of times) and persistent (over several months) microfluidic control. We demonstrated that the microfluidic platform is reusable (dozens of times) for stable, reproducible, and high throughput generation of tumors with uniform size. Various heterotypic and homotypic 3D tumor arrays can be produced successfully in the device based on robust pneumatic control. On-chip monitoring and analysis of tumor phenotypes and responses to different culture conditions and chemotherapies were also achieved in real-time in the microfluidic platform. The results indicate that fibroblasts cocultured with tumor cells positively promote the phenotypical appearance of heterotypic tumors. This microfluidic advancement offers a new methodological approach for the development of high-performance and non-disposable 3D culture systems and for tissue-mimicking cancer research. We believe that it could be valuable for various tumor-related research fields such as oncology, pharmacology, tissue engineering, and bioimaging. PMID- 27714004 TI - Yerba mate (Ilex paraguariensis) inhibits lymphocyte activation in vitro. AB - Yerba mate (YM) has been shown to have anti-inflammatory properties in several studies. However, this effect has been found mainly in obesity-related inflammation. The aim of this work was to study the effect of YM on cultured peripheral blood mononuclear cells to see whether it has anti-inflammatory properties. We stimulated peripheral blood mononuclear cells in vitro with phytohemagglutinin (PHA) in the presence of yerba mate and determined their activation by measuring the expression of CD25 by flow cytometry. We observed that YM treatment produced a dose-dependent reduction in PBMC activation (CD25 positive cells) when they were stimulated with PHA. This effect was also observed in T cells' (CD3 positive) subpopulation. Microarray analysis revealed the differential expression of 128 genes in YM-treated cells. According to a protein protein interaction database, these genes were highly connected and they are involved in the inflammatory response. In summary, it was demonstrated that YM produces a reduction in the amount of activated cells under the stimulation of PHA. Therefore, it might be used in diseases with an inflammatory component. PMID- 27714005 TI - Polydatin attenuates d-galactose-induced liver and brain damage through its anti oxidative, anti-inflammatory and anti-apoptotic effects in mice. AB - Accumulating evidence has shown that chronic injection of d-galactose (d-gal) can mimic natural aging, with accompanying liver and brain injury. Oxidative stress and apoptosis play a vital role in the aging process. In this study, the antioxidant ability of polydatin (PD) was investigated using four established in vitro systems. An in vivo study was also conducted to investigate the possible protective effect of PD on d-gal-induced liver and brain damage. The results showed that PD had remarkable in vitro free radical scavenging activity on 2,2 diphenyl-1-picryl-hydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzo-thiazoline-6 sulfonic acid) (ABTS+) radical ions, and hydroxyl and superoxide anions. Results in vivo indicated that, in a group treated with d-gal plus PD, PD remarkably decreased the depression of body weight and organ indexes, reduced the levels of the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and alleviated alterations in liver and brain histopathology. PD also significantly decreased the level of MDA and elevated SOD, GSH-Px, CAT activity and T-AOC levels in the liver and brain. In addition, the levels of inflammatory mediators, such as TNF-alpha, IL-1beta and IL-6 in serum were markedly reduced after PD treatment. Western blotting results revealed that PD treatment noticeably attenuated the d-gal-induced elevation of Bcl-2/Bax ratio and caspase 3 protein expression in liver and brain. Overall, our findings indicate that PD treatment could effectively attenuate d-gal-induced liver and brain damage, and the mechanism might be associated with decreasing the oxidative stress, inflammation and apoptosis caused by d-gal. PD holds good potential for further development into a promising pharmaceutical candidate for the treatment of age associated diseases. PMID- 27714006 TI - Microfluidics in microbiology: putting a magnifying glass on microbes. AB - Microfluidic technologies enable unique studies in the field of microbiology to facilitate our understanding of microorganisms. Using miniaturized and high throughput experimental capabilities in microfluidics, devices with controlled microenvironments can be created for microbial studies in research fields such as healthcare and green energy. In this research highlight, we describe recently developed tools for diagnostic assays, high-throughput mutant screening, and the study of human disease development as well as a future outlook on microbes for renewable energy. PMID- 27714007 TI - Multiple actuation microvalves in wax microfluidics. AB - Microvalves are an essential component of microfluidic devices. In this work, a low-consumption (<35 mJ), fast-response (<0.3 s), small footprint (<0.5 mm2) wax microvalve capable of multiple actuation is described. This phase-change microvalve is electrically controlled, simple to operate and can be easily fabricated as a fully integrated element of wax microfluidic devices through a special decal-transfer microlithographic process. The valve is inherently latched and leak-proof to at least 100 kPa. A minimum pressure of 3 kPa is required for valve opening. Maximum pressures for a successful closing in air and liquid are 90 and 40 kPa, respectively. The wax valve exhibits reversible open-close behaviour without failure for up to 10 actuation cycles in air (60 kPa) and 5 in water (30 kPa). To the best of our knowledge, this microvalve has the lowest energy consumption (two orders of magnitude lower) reported so far for a plug type phase-change valve. Furthermore, its size, actuation mechanism and fabrication technology make it suitable for large-scale integration in microfluidic devices. Detailed characteristics in fabrication and actuation of the wax microfluidic valve as well as a test example of its performance for liquid dispensing are reported. PMID- 27714008 TI - Importance of proximity measures in clustering of cancer and miRNA datasets: proposal of an automated framework. AB - Distance plays an important role in the clustering process for allocating data points to different clusters. Several distance or proximity measures have been developed and reported in the literature to determine dissimilarities between two given points. The choice of distance measure depends on a particular domain as well as different data sets of the same domain. It is important to automatically determine the appropriate distance measure which acts best for a particular data set. In this study we have developed an automatic clustering technique using the search capability of multiobjective optimization which can automatically determine the relevant distance measure and the corresponding partitioning from a given data set. Our proposed automated framework is generic in nature i.e., any number of different distance measures can be incorporated into it. In our work we have used four existing widely used distance measures, i.e., Euclidean, line symmetry, point symmetry and city block distance to be explored for each data set. In order to measure the richness of an obtained partitioning using a particular distance, four cluster validity indices, the Silhouette index, the DB index, the adjusted rand index and classification accuracy are used. A new encoding strategy which can encode the set of cluster centers and the particular distance function is used to represent the problem. The appropriate distance function and the corresponding partitioning are determined using the search capability of a multiobjective optimization based technique. The efficiency of the proposed technique is shown on clustering three microRNA and three microarray gene expression data sets having varying complexities. The results show the usefulness of the proposed automated approach. PMID- 27714009 TI - Stiffness of the C-terminal disordered linker affects the geometry of the active site in endoglucanase Cel8A. AB - Cellulosomes are complex multi-enzyme machineries which efficiently degrade plant cell-wall polysaccharides. The multiple domains of the cellulosome proteins are often tethered together by intrinsically disordered regions. The properties and functions of these disordered linkers are not well understood. In this work, we study endoglucanase Cel8A, which is a relevant enzymatic component of the cellulosomes of Clostridium thermocellum. We use both all-atom and coarse-grained simulations to investigate how the conformations of the catalytic domain of Cel8A are affected by the disordered linker at its C terminus. We find that when the endoglucanase is bound to its substrate, the effective stiffness of the linker can influence the distances between groups of amino-acid residues throughout the entire enzymatic domain. In particular, variations in the linker stiffness can lead to small changes in the geometry of the active-site cleft. We suggest that such geometrical changes may have an effect on the catalytic activity of the enzyme. PMID- 27714010 TI - Correction: Nanoscale mechanics guides cellular decision making.

PMID- 27714011 TI - An on-demand gas segmented flow generator with high spatiotemporal resolution for in vivo analysis of neuronal response in C. elegans. AB - Studies of chemo-sensing in C. elegans to fluctuating gaseous cues are limited due to the lack of a method of precise gas control. In this paper, we describe a microfluidic-based on-demand gas segmented flow generator for performing fluctuating gaseous stimulations to worms. This highly versatile and programmable micro-device integrated with pneumatic valves for flexible and stable gas flow control and worm immobilization enabled us to examine the temporal features of neuronal response to multiple gas pulses with sub-second precision. As a result, we demonstrated the capability of the micro-device to generate repetitive gaseous chemical pulses with varying durations. By characterizing intracellular calcium signals, we showed that URX sensory neurons were sensitive to O2 pulses with duration of more than 0.5 s. Furthermore, URX neuronal adaptation and recovery in response to gaseous chemical pulses were investigated by varying the durations and intervals. The developed microfluidic system is shown to be a useful tool for studying the dynamics of in vivo gas-evoked neuronal responses and revealing the temporal properties of environmental stimulations. PMID- 27714012 TI - Molecular dynamics studies on the DNA-binding process of ERG. AB - The ETS family of transcription factors regulate gene targets by binding to a core GGAA DNA-sequence. The ETS factor ERG is required for homeostasis and lineage-specific functions in endothelial cells, some subset of haemopoietic cells and chondrocytes; its ectopic expression is linked to oncogenesis in multiple tissues. To date details of the DNA-binding process of ERG including DNA sequence recognition outside the core GGAA-sequence are largely unknown. We combined available structural and experimental data to perform molecular dynamics simulations to study the DNA-binding process of ERG. In particular we were able to reproduce the ERG DNA-complex with a DNA-binding simulation starting in an unbound configuration with a final root-mean-square-deviation (RMSD) of 2.1 A to the core ETS domain DNA-complex crystal structure. This allowed us to elucidate the relevance of amino acids involved in the formation of the ERG DNA-complex and to identify Arg385 as a novel key residue in the DNA-binding process. Moreover we were able to show that water-mediated hydrogen bonds are present between ERG and DNA in our simulations and that those interactions have the potential to achieve sequence recognition outside the GGAA core DNA-sequence. The methodology employed in this study shows the promising capabilities of modern molecular dynamics simulations in the field of protein DNA-interactions. PMID- 27714013 TI - Characterization of human pineal gland proteome. AB - The pineal gland is a neuroendocrine gland located at the center of the brain. It is known to regulate various physiological functions in the body through secretion of the neurohormone melatonin. Comprehensive characterization of the human pineal gland proteome has not been undertaken to date. We employed a high resolution mass spectrometry-based approach to characterize the proteome of the human pineal gland. A total of 5874 proteins were identified from the human pineal gland in this study. Of these, 5820 proteins were identified from the human pineal gland for the first time. Interestingly, 1136 proteins from the human pineal gland were found to contain a signal peptide domain, which indicates the secretory nature of these proteins. An unbiased global proteomic profile of this biomedically important organ should benefit molecular research to unravel the role of the pineal gland in neuropsychiatric and neurodegenerative diseases. PMID- 27714014 TI - Magnetophoretic transistors in a tri-axial magnetic field. AB - The ability to direct and sort individual biological and non-biological particles into spatially addressable locations is fundamentally important to the emerging field of single cell biology. Towards this goal, we demonstrate a new class of magnetophoretic transistors, which can switch single magnetically labeled cells and magnetic beads between different paths in a microfluidic chamber. Compared with prior work on magnetophoretic transistors driven by a two-dimensional in plane rotating field, the addition of a vertical magnetic field bias provides significant advantages in preventing the formation of particle clumps and in better replicating the operating principles of circuits in general. However, the three-dimensional driving field requires a complete redesign of the magnetic track geometry and switching electrodes. We have solved this problem by developing several types of transistor geometries which can switch particles between two different tracks by either presenting a local energy barrier or by repelling magnetic objects away from a given track, hereby denoted as "barrier" and "repulsion" transistors, respectively. For both types of transistors, we observe complete switching of magnetic objects with currents of ~40 mA, which is consistent over a range of particle sizes (8-15 MUm). The switching efficiency was also tested at various magnetic field strengths (50-90 Oe) and driving frequencies (0.1-0.6 Hz); however, we again found that the device performance only weakly depended on these parameters. These findings support the use of these novel transistor geometries to form circuit architectures in which cells can be placed in defined locations and retrieved on demand. PMID- 27714015 TI - A link between chromatin condensation mechanisms and Huntington's disease: connecting the dots. AB - Huntington's disease is a rare neurodegenerative disorder whose complex pathophysiology exhibits system-wide changes in the body, with striking and debilitating clinical features targeting the central nervous system. Among the various molecular functions affected in this disease, mitochondrial dysfunction and transcriptional dysregulation are some of the most studied aspects of this disease. However, there is evidence of the involvement of a mutant Huntingtin protein in the processes of DNA damage, chromosome condensation and DNA repair. This review attempts to briefly recapitulate the clinical features, model systems used to study the disease, major molecular processes affected, and, more importantly, examines recent evidence for the involvement of the mutant Huntingtin protein in the processes regulating chromosome condensation, leading to DNA damage response and neuronal death.

AB - We utilize an ac electric field to trigger the on-demand fusion of two aqueous cores inside water-in-oil-in-water (W/O/W) double-emulsion drops. We attribute the coalescence phenomenon to field-induced structural polarization and breakdown of the stress balance at interfaces. This method provides not only accurate control over the reaction time of coalescence but also protection of the reaction from cross contamination. PMID- 27714018 TI - Enhanced energy harvesting by concentration gradient-driven ion transport in SBA 15 mesoporous silica thin films. AB - Nanofluidic energy harvesting systems have attracted interest in the field of battery application, particularly for miniaturized electrical devices, because they possess excellent energy conversion capability for their size. In this study, a mesoporous silica (MPS)-based nanofluidic energy harvesting system was fabricated and selective ion transport in mesopores as a function of the salt gradient was investigated. Aqueous solutions with three different kinds of monovalent electrolytes-KCl, NaCl, and LiCl-with different diffusion coefficients (D+) were considered. The highest power density was 3.90 W m-2 for KCl, followed by 2.39 W m-2 for NaCl and 1.29 W m-2 for LiCl. Furthermore, the dependency of power density on the type of cation employed indicates that the harvested energy increases as the cation mobility increases, particularly at high concentrations. This cation-specific dependency suggests that the maximum power density increases by increasing the diffusion coefficient ratio of cations to anions, making this ratio a critical parameter in enhancing the performance of nanofluidic energy harvesting systems with extremely small pores ranging from 2 to 3 nm. PMID- 27714019 TI - Continuous plasma extraction under viscoelastic fluid in a straight channel with asymmetrical expansion-contraction cavity arrays. AB - In this paper, continuous plasma extraction under viscoelastic fluid in a straight channel with asymmetrical expansion-contraction cavity arrays (ECCA channel) is demonstrated by exploiting the Dean-flow-coupled elasto-inertial effects. First, the forces experienced by particles in the ECCA channel were discussed. Then, 4.8 MUm diameter particles, which mimic the behaviour of red blood cells (RBCs), were used to study the effects of poly(ethylene oxide) (PEO) concentrations and flow rates on particle viscoelastic focusing. Also, 3 MUm, 4.8 MUm and 10 MUm diameter particles, which are comparable in size to platelets, RBCs, and white blood cells (WBCs), respectively, were used to study the effect of particle size on particle viscoelastic focusing. Finally, plasma extraction from diluted blood samples under viscoelastic conditions was conducted, and the purity of the collected blood plasma was measured. After two series of filtration with the same ECCA channel, the purity of 3 MUm, 4.8 MUm and 10 MUm diameter particles reached 100%, and the plasma purity reached 99.99%, as measured by a hemocytometer. In addition, flow cytometry data further validated the filtration performance of blood plasma. By exploiting the Dean-flow-coupled elasto-inertial effects, the ECCA channel offers a continuous, sheathless, and high purity plasma extraction. PMID- 27714020 TI - Flow-less and shape-conformable CNT sheet nanogenerator for self-powered motion sensor. AB - A carbon nanotube (CNT) sheet nanogenerator that does not require any liquid or gas flow for power generation is developed on the basis of Coulombic interactions, making the device attractive as a building block for self-powered sensors. The working principle of the CNT nanogenerator is probed in terms of sweeping speed, distance between charged object and nanotube sheet, surface charge, and number of layers of nanotube sheet. The nature of the CNT sheet and its formation process is such that simply winding the CNT sheet stripe n times around a substrate leads to increasing the power n times. For a practical demonstration of the CNT nanogenerator, a self-powered sensor array screen is developed that can read finger movements, just as with a finger command on a smartphone screen. PMID- 27714021 TI - Toxicological aspects of soluble titanium - a review of in vitro and in vivo studies. AB - Owing to the widespread use of titanium dioxide (TiO2) in various food, household and cosmetic products and in industry, the number of publications concerned with the potential toxic effects and health risks related to this substance in both bulk and nano form is steadily increasing. On the other hand, there is also a third form of titanium, ionic, which is produced by the biodegradation of Ti alloy implants. Thus, the growing population of implant recipients should raise concerns about the impact of soluble Ti on human health. Today, the mechanism of this metal's action on the human body is still not fully understood. This review aims to explore the health risks associated especially with long-term use of titanium implants. The paper provides an analysis of data available from the last 10 years concerning investigations of the adverse effects of Ti ions, including in vitro models of various tissues, in vivo studies of implant corrosion in animals and humans, and potential pathomechanisms of the adverse health impact induced by soluble titanium. PMID- 27714022 TI - Hot off the press.

PMID- 27714023 TI - Launching deep subwavelength bulk plasmon polaritons through hyperbolic metamaterials for surface imaging with a tuneable ultra-short illumination depth. AB - Hyperbolic metamaterials (HMMs) composed of multiple nanometal-dielectric films are proposed for launching deep subwavelength bulk plasmon polaritons (BPPs) as uniform, large area surface imaging illumination sources with a skin depth even beyond 10 nm. Benefiting from the coupled plasmon modes over a wide wavevector range in HMMs, the illumination depth could be continually tuned, simply by adjusting the incidence angle of light impinged on a grating structure for BPP excitation. As an example, the illumination depths of 19-63 nm at a light wavelength of 532 nm are demonstrated with SiO2-Ag multifilms. Moreover, the structure holds its deep subwavelength illumination depth for a broad light wavelength range, resembling that of light total internal reflection in a prism with an ultra high refractive index. Furthermore, a fluorescent nanoparticle based micro-zone system was employed for estimating the illumination depth of the HMM structure. The method is believed to provide access for surface imaging features in ultra thin layers especially for bio-samples. PMID- 27714024 TI - Valence and oxide impurities in MoS2 and WS2 dramatically change their electrocatalytic activity towards proton reduction. AB - Layered molybdenum disulfide (MoS2) and tungsten disulfide (WS2) have received renewed interest in recent years as they are catalytic towards the hydrogen evolution reaction (HER) and they are touted as future replacements of platinum in electrolyzers. There is a significant discrepancy in the found onset potentials of MoS2 and WS2 towards the hydrogen evolution reaction. Here we show that the presence of valence sulfide impurities, such as MoS3 and WS3, and their oxide counterparts, such as MoO2, MoO3 and WO2, WO3 can contribute to the catalytic activity towards hydronium reduction to hydrogen of MoS2 and WS2. Therefore, it is highly possible that the differences in the reported onset potentials and thus catalytic activities of the MoS2 and WS2 are due to the presence of catalytic impurities. PMID- 27714025 TI - A label-free infrared opto-fluidic method for real-time determination of flow rate and concentration with temperature cross-sensitivity compensation. AB - The ability to accurately measure the flow rate, concentration, and temperature in real-time in micro total analysis systems (MUTAS) is crucial when improving their practical sensing capabilities within extremely small volumes. Our label free infrared (1500-1600 nm) opto-fluidic method, presented in this study, utilizes a cantilever-based flow meter integrated with two parallel optical fiber Fabry-Perot interferometers (FPIs). The first FPI serves as an ultra-sensitive flow meter and includes a Fiber Bragg Grating (FBG) tip for localized temperature sensing. The second FPI has a fabricated photopolymer micro-tip for highly sensitive refractive index (RI) determination. In this work, we performed 3-D simulation analysis to characterize cantilever deflection as well as temperature distribution and its effect on the RI. The experimental results from temperature cross-sensitivity analysis lead to real-time measurement resolutions of 5 nL min 1, 1 * 10-6 RIU and 0.05 degrees C, for the flow rate, refractive index, and temperature, respectively. PMID- 27714026 TI - Multiplex SNP genotyping in whole blood using an integrated microfluidic lab-on-a chip. AB - Pharmacogenetics has often been touted as a cornerstone for precision medicine as detailed knowledge of a specific genetic makeup may allow for accurate predictions of a patient's individual drug response. Still, the widespread use of genetic tests is limited as they remain expensive and cumbersome, requiring sophisticated tools and highly trained personnel. In order for pharmacogenetics to reach its full potential, more cost-effective and easily accessible genotyping methods are desired. To meet these challenges, we present a silicon-based integrated microsystem for the detection of multiple single nucleotide polymorphisms (SNPs) directly from human blood. The device combines a blood lysis chamber, a cross-flow filter, a T-junction mixer, and a microreactor for quantitative polymerase chain reaction (qPCR). Using this device, successful on chip genotyping of two clinically relevant SNPs in human CYP2C9 gene was demonstrated with TaqMan assays, starting from blood. The two SNPs were detected simultaneously by introducing a sequence of plugs, each containing a different set of primers and probes. The method can be easily extended to detect several SNPs. The microsystem described here offers a rapid, reproducible, and accurate sample-to-answer technology enabling multiplex SNP profiling in point-of-care settings, bringing pharmacogenetics-based precision medicine a step closer to reality. PMID- 27714027 TI - Characterization of substrate binding and enzymatic removal of a 3-methyladenine lesion from genomic DNA with TAG of MDR A. baumannii. AB - The rise of multiple-drug resistance in bacterial pathogens imposes a serious public health concern and has led to increased interest in studying various pathways as well as enzymes. Different DNA glycosylases collaborate during bacterial infection and disease by overcoming the effects of ROS- and RNS mediated host innate immunity response. 3-Methyladenine DNA glycosylase I, an essential DNA repair enzyme, was chosen for the present study from the MDR species of A. baumannii. The enzyme was especially chosen because of its functional significance in A. baumannii and due to its structural variation from its human homologue. MDR strains such as A. baumannii are interesting targets owing to their evolved mechanisms of evading a host defence. In the absence of any structural information, the enzyme was characterized biophysically and biochemically. Binding studies with 3mA and Zn2+ indicated that the activity of TAG-Ab is an enthalpy-driven process. Fluorescence thermal denaturation studies described that the denaturation of TAG-Ab is a two-step process. Modified RP-HPLC based glycosylase assay attested that the heterologously expressed and purified TAG-Ab enzyme is active and catalyses the removal of 3mA. Other binding parameters and the effect of adenine on substrate binding are also discussed in detail. PMID- 27714028 TI - Robust scalable high throughput production of monodisperse drops. AB - Monodisperse drops with diameters between 20 MUm and 200 MUm can be used to produce particles or capsules for many applications such as for cosmetics, food, and biotechnology. Drops composed of low viscosity fluids can be conveniently made using microfluidic devices. However, the throughput of microfluidic devices is limited and scale-up, achieved by increasing the number of devices run in parallel, can compromise the narrow drop-size distribution. In this paper, we present a microfluidic device, the millipede device, which forms drops through a static instability such that the fluid volume that is pinched off is the same every time a drop forms. As a result, the drops are highly monodisperse because their size is solely determined by the device geometry. This makes the operation of the device very robust. Therefore, the device can be scaled to a large number of nozzles operating simultaneously on the same chip; we demonstrate the operation of more than 500 nozzles on a single chip that produces up to 150 mL h 1 of highly monodisperse drops.

PMID- 27714030 TI - Identification of potential CCR5 inhibitors through pharmacophore-based virtual screening, molecular dynamics simulation and binding free energy analysis. AB - CC chemokine receptor 5 (CCR5), a member of G protein-coupled receptors (GPCRs), plays a vital role in inflammatory responses to infection. Alterations in the expression of CCR5 have been correlated with disease progression in many types of cancers. The idea of using CCR5 as a target for therapeutic intervention has been demonstrated to prevent disease progression. To date, only a few compounds have been reported as CCR5 inhibitors. In this study, a series of CCR5 antagonists were used to construct pharmacophore models. Then the optimal model was utilized as a 3D query to identify novel chemical entities from structural databases. After refinement by molecular docking, drug-likeness analysis, molecular dynamics simulations (MDS) and binding free energy analysis, three potential inhibitors (25, 29 and 45) were identified. MD simulations suggested that the screened compounds retained the important common binding mode known for CCR5 inhibitors (maraviroc and nifeviroc), which occupied the bottom of a pocket and stabilized the conformation of CCR5. During the binding process, van der Waals interactions provided the substantial driving force. The most favorable contributions were from Tyr37, Trp86, Tyr89, Tyr108, Phe109, Phe112, Gln194, Thr195, Ile198, Trp248, Tyr251, Leu255, Thr259, Met279, Glu283 and Met287. The above results suggest that the hybrid strategy would provide a basis for rational drug design. PMID- 27714031 TI - Designing metallodrugs with nuclease and protease activity. AB - The accidental discovery of cisplatin some 50 years ago generated renewed interest in metallopharmaceuticals. Beyond cisplatin, many useful metallodrugs have been synthesized for the diagnosis and treatment of various diseases, but toxicity concerns, and the propensity to induce chemoresistance and secondary cancers make it imperative to search for novel metallodrugs that address these limitations. The Amino Terminal Cu(ii) and Ni(ii) (ATCUN) binding motif has emerged as a suitable template to design catalytic metallodrugs with nuclease and protease activities. Unlike their classical counterparts, ATCUN-based metallodrugs exhibit low toxicity, employ novel mechanisms to irreversibly inactivate disease-associated genes or proteins providing in principle, a channel to circumvent the rapid emergence of chemoresistance. The ATCUN motif thus presents novel strategies for the treatment of many diseases including cancers, HIV and infections caused by drug-resistant bacteria at the genetic level. This review discusses their design, mechanisms of action and potential for further development to expand their scope of application. PMID- 27714032 TI - Insight into a reversible energy transfer system. AB - Resonance energy transfer (RET) processes have wide applications; these processes involve a unidirectional energy transfer from a particular donor to a particular acceptor. Here, we report a plasmonic resonance energy transfer (PRET), which occurs from the surface of gold nanoparticles to fluorescent organic dyes, and coexists with a nanometal surface energy transfer (NSET) that operates in the reverse direction. The coexistence of both PRET and NSET in opposite directions means that the roles of both donor and acceptor can be interchanged, which could be identified by using spectrofluorometric measurements and light scattering dark field microscopic imaging. The experimental data could be further theoretically supported using Persson and Lang's model, the quasi-static approximation and finite-difference time-domain simulation. Moreover, disruption of the PRET process by altering the energy transfer pairs suggests that interactions occur inside the reversible energy transfer system, which manifest by increasing the fluorescence quenching efficiency of the NSET process.

AB - Multiple advanced logic circuits including the full-adder, full-subtract and majority logic gate have been successfully realized on a DNA/GO platform for the first time. All the logic gates were implemented in an enzyme-free condition. The investigation provides a wider field of vision towards prototypical DNA-based algebra logical operations and promotes the development of advanced logic circuits. PMID- 27714034 TI - Protein-coding genes combined with long non-coding RNAs predict prognosis in esophageal squamous cell carcinoma patients as a novel clinical multi-dimensional signature. AB - Esophageal carcinoma is one of the most malignant gastrointestinal cancers worldwide, and has a high mortality rate. Both protein-coding genes (PCGs) and long non-coding RNAs (lncRNAs) have been shown to play an important role in the development of malignant tumors. However, the clinical significance of PCGs combined lncRNAs is yet to be investigated in esophageal squamous cell carcinoma (ESCC). Using probe re-annotation, univariable Cox regression and the random survival forest algorithm to identify PCG-lncRNA combinations predictive of the overall survival, we found a signature comprised of three PCGs (ANGPTL7, OBP2A, SLC27A5) and two lncRNAs (RP11-702B10.1, RP11-523H24.3) to have the highest accurate prediction, with an area under ROC curve (AUC) of 0.85 in the training group and 0.63 in the test group, and it was significantly associated with the survival of ESCC patients in the training group (median survival: 32.2 months > 60 months, P < 0.001). The application of the signature to the test group showed similar prognostic values (median survival: 39.3 months vs. >60 months, P = 0.03). The chi-square test and multivariable Cox regression analysis showed that the three-PCG, two-lncRNA signature was an independent prognostic factor for patients with ESCC. Stratified analysis suggested that the PCG-lncRNA signature combined with the TNM stage could more accurately categorize ESCC patients. Our study suggests that the three-PCG, two-lncRNA signature has clinical significance for the prognosis of patients with ESCC. This signature can serve as a potential auxiliary biomarker of the TNM stage to subdivide ESCC patients more precisely.

AB - Single-layer transition-metal dichalcogenides (TMDs) such as MoS2 and MoSe2 exhibit unique electronic band structures ideal for hosting many exotic spin orbital orderings. It has been widely accepted that Rashba spin splitting (RSS) is linearly proportional to the external field in heterostructure interfaces or to the potential gradient in polar materials. Surprisingly, an extraordinary nonlinear dependence of RSS is found in semiconducting TMD monolayers under a gate field. In contrast to small and constant RSS in polar materials, the potential gradient in non-polar TMDs gradually increases with the gate bias, resulting in nonlinear RSS with a Rashba coefficient an order-of-magnitude larger than the linear one. Most strikingly, under a large gate field MoSe2 demonstrates the largest anisotropic spin splitting among all known semiconductors to our knowledge. Based on the k.p model via symmetry analysis, we identify that the third-order contributions are responsible for the large nonlinear Rashba splitting. The gate tunable spin splitting found in semiconducting pristine TMD monolayers promises future spintronics applications in that spin polarized electrons can be generated by external gating in an experimentally accessible way. PMID- 27714036 TI - A solid-state cation exchange reaction to form multiple metal oxide heterostructure nanowires. AB - Metal oxide nanostructures have been investigated extensively due to their wide range of physical properties; zinc oxide is one of the most promising materials. It exhibits fascinating functional properties and various types of morphologies. In particular, ZnO heterostructures have attracted great attention because their performance can be modified and further improved by the addition of other materials. In this study, we successfully transformed ZnO nanowires (NWs) into multiple ZnO/Al2O3 heterostructure NWs via a solid-state cation exchange reaction. The experiment was carried out in situ via an ultrahigh vacuum transmission electron microscope (UHV-TEM), which was equipped with a video recorder. Moreover, we analyzed the structure and composition of the heterostructure NWs by Cs-corrected STEM equipped with EDS. Based on these experimental results, we inferred a cation exchange reaction ion path model. Additionally, we investigated the defects that appeared after the cation reaction, which resulted from the remaining zinc ions. These multiple heterostructure ZnO/Al2O3 NWs exhibited excellent UV sensing sensitivity and efficiency. PMID- 27714037 TI - Ultra-efficient electrocatalytic hydrogen evolution at one-step carbonization generated molybdenum carbide nanosheets/N-doped carbon. AB - The hydrogen evolution reaction (HER) from water through electrocatalysis using highly active noble metal-free catalysts as an alternative to precious Pt-based catalysts holds great promise for clean and renewable energy systems. Here, Mo2C nanosheets well-regulated in N-doped carbon (MCNS/NC)are facilely achieved by in situ confining carburization of a Mo-based inorganic-organic lamellar mesostructure at 900 degrees C, and demonstrated for the first time as an ultra efficient and durable HER catalyst. The MCNS/NC displays a very low onset overpotential of ~0 mV and an overpotential of 19 mV at 10 mA cm-2 with a small Tafel slope of 28.9 mV dec-1 in acid media, which is remarkably superior to most other transition metal-based catalysts and comparable to commercial Pt/C. The HER kinetics are further studied by EIS and Tafel slope analysis, suggesting the dominant Volmer-Tafel mechanism. An "outside-in" carburization mechanism for the evolution of MCNS/NC is proposed through detailed investigation of the samples annealed at different temperatures. This study highlights the importance of designing well-regulated functional nanostructures combined with a conductive carbonaceous matrix for versatile applications. PMID- 27714038 TI - Coated and uncoated cellophane as materials for microplates and open-channel microfluidics devices. AB - This communication describes the use of uncoated cellophane (regenerated cellulose films) for the fabrication of microplates, and the use of coated cellophane for the fabrication of open-channel microfluidic devices. The microplates based on uncoated cellophane are particularly interesting for applications that require high transparency in the ultraviolet (UV) regime, and offer a low-cost alternative to expensive quartz-well plates. Uncoated cellophane is also resistant to damage by various solvents. The microfluidic devices, based on coated cellophane, can have features with dimensions as small as 500 MUm, and complex, non-planar geometries. Electrodes can be printed on the surface of the coated cellophane, and embedded in microfluidic devices, to develop resistive heaters and electroanalytical devices for flow injection analysis, and continuous flow electrochemiluminescence (ECL) applications. These open-channel devices are appropriate for applications where optical transparency (especially in the visible regime), resistance to damage by water, biocompatibility and biodegradability are important. Cellophane microfluidic systems complement existing cellulose-based paper microfluidic systems, and provide an alternative to other materials used in microfluidics, such as synthetic polymers or glass. Cellulose films are plausible materials for uses in integrated microfluidic systems for diagnostics, analyses, cell-culture, and MEMS. PMID- 27714039 TI - Unveiling the atomic structure and electronic properties of atomically thin boron sheets on an Ag(111) surface. AB - Two-dimensional (2D) boron sheets (i.e., borophene) have a huge potential as a basic building block in nanoelectronics and optoelectronics; such a situation is greatly promoted by recent experiments on fabrication of borophene on silver substrates. However, the fundamental atomic structure of borophene on the Ag substrate is still under debate, which greatly impedes further exploration of its properties. Herein, the atomic structure and electronic properties of borophene on an Ag(111) surface have been studied using first-principles calculations and ab initio molecular dynamics simulations. Our results reveal that there exist three energetically favorable borophene structures (beta5, chi1, and chi2) on the Ag(111) surface and their simulated STM images are in good agreement with experimental results, suggesting the coexistence of boron phases during the growth. All these stable borophene structures have a planar structure with slight surface buckling (~0.15 A) and relatively high hexagonal vacancy density (1/6 and 1/5) and exhibit typical metallic conductivity. These findings not only can be applied to solve the experimental controversies about the atomic structure of borophene on the Ag substrate but also provide a theoretical basis for exploring the fundamental properties and applications of 2D boron sheets. PMID- 27714040 TI - Photon-induced generation and spatial control of extreme pressure at the nanoscale with a gold bowtie nano-antenna platform. AB - Precise spatial and temporal control of pressure stimulation at the nanometer scale is essential for the fabrication and manipulation of nano-objects, and for exploring single-molecule behaviour of matter under extreme conditions. However, state-of-the-art nano-mechanical transducers require sophisticated driving hardware and are currently limited to moderate pressure regimes. Here we report a gold plasmonic bowtie (AuBT) nano-antennas array that can generate extreme pressure stimulus of ~100 GPa in the ps (10-12 s) time scale with sub-wavelength resolution upon irradiation with ultra-short laser pulses. Our method leverages the non-linear interaction of photons with water molecules to excite a nano plasma in the plasmon-enhanced near-field and induce extreme thermodynamic states. The proposed method utilizes laser pulses, which in contrast to micro- and nano-mechanical actuators offers simplicity and versatility. We present time resolved shadowgraphic imaging, electron microscopy and simulation data that suggest that our platform can efficiently create cavitation nano-bubbles and generate intense pressure in specific patterns, which can be controlled by the selective excitation of plasmon modes of distinct polarizations. This novel platform should enable probing non-invasively the mechanical response of cells and single-molecules at time and pressure regimes that are currently difficult to reach with other methods.

AB - Covering: up to April 2016Aspergillus and Penicillium are fungal species known to produce a high diversity of secondary metabolites, many of them endowed with interesting bioactivity. The small but steadily growing family of the naturally occurring 5-hydroxy-4-aryl-quinolin-2(1H)-one alkaloids and closely related compounds, which represent the results of various research projects that spanned over 20 years and involved scientists from different continents, are covered here. Emphasis is placed on the isolation and chemical structures of the different compounds, together with their source microorganisms, environmental conditions, country or region of origin, and relevant biological activities. In addition, stereochemical aspects, as well as the proposed biosynthetic pathways for the different members, and the incipient synthetic efforts towards some of the compounds or their key intermediates, are discussed in detail. PMID- 27714042 TI - BiKEGG: a COBRA toolbox extension for bridging the BiGG and KEGG databases. AB - Development of an interface tool between the Biochemical, Genetic and Genomic (BiGG) and KEGG databases is necessary for simultaneous access to the features of both databases. For this purpose, we present the BiKEGG toolbox, an open source COBRA toolbox extension providing a set of functions to infer the reaction correspondences between the KEGG reaction identifiers and those in the BiGG knowledgebase using a combination of manual verification and computational methods. Inferred reaction correspondences using this approach are supported by evidence from the literature, which provides a higher number of reconciled reactions between these two databases compared to the MetaNetX and MetRxn databases. This set of equivalent reactions is then used to automatically superimpose the predicted fluxes using COBRA methods on classical KEGG pathway maps or to create a customized metabolic map based on the KEGG global metabolic pathway, and to find the corresponding reactions in BiGG based on the genome annotation of an organism in the KEGG database. Customized metabolic maps can be created for a set of pathways of interest, for the whole KEGG global map or exclusively for all pathways for which there exists at least one flux carrying reaction. This flexibility in visualization enables BiKEGG to indicate reaction directionality as well as to visualize the reaction fluxes for different static or dynamic conditions in an animated manner. BiKEGG allows the user to export (1) the output visualized metabolic maps to various standard image formats or save them as a video or animated GIF file, and (2) the equivalent reactions for an organism as an Excel spreadsheet. PMID- 27714043 TI - Investigation of uranium interactions with calcium phosphate-binding proteins using ICP/MS and CE-ICP/MS. AB - During long-term exposure, uranium accumulates in bone. Since uranium in U(vi) complexes shares similar coordination properties to calcium, this toxicant is assumed to be exchanged with calcium ions at the surfaces of bone mineral crystals. Recently, two proteins involved in bone turnover, fetuin A and osteopontin, were shown to exhibit a high affinity for U(vi). A common biochemical feature of both fetuin A and osteopontin is their inhibiting role in calcium phosphate precipitation. Therefore it is conceivable that complexation of U(vi) with these proteins may alter their interaction with calcium and/or calcium phosphate. Quantitative analyses of calcium, phosphorus and uranium performed using inductively coupled plasma/mass spectrometry (ICP/MS) demonstrated the inhibition of the precipitation of calcium phosphate by fetuin A and osteopontin for 2 h. In addition, the presence of U(vi) did not seem to alter the duration of this process. However, dynamic light scattering studies revealed that the size of the colloidal particles formed with osteopontin was altered by the presence of U(vi) in a concentration-dependent manner. Finally, using hyphenated capillary electrophoresis-ICP/MS (CE-ICP/MS), we showed that in these systems, at a low concentration of U(vi) (protein : U(vi) 8 : 1), U(vi) might remain in solution by forming a complex with proteins and not by sequestration of a precipitate of either autunite or uranyl orthophosphate. PMID- 27714044 TI - Knockdown of copper-transporting ATPase 1 (Atp7a) impairs iron flux in fully differentiated rat (IEC-6) and human (Caco-2) intestinal epithelial cells. AB - Intestinal iron absorption is highly regulated since no mechanism for iron excretion exists. We previously demonstrated that expression of an intestinal copper transporter (Atp7a) increases in parallel with genes encoding iron transporters in the rat duodenal epithelium during iron deprivation (Am. J. Physiol.: Gastrointest. Liver Physiol., 2005, 288, G964-G971). This led us to postulate that Atp7a may influence intestinal iron flux. Therefore, to test the hypothesis that Atp7a is required for optimal iron transport, we silenced Atp7a in rat IEC-6 and human Caco-2 cells. Iron transport was subsequently quantified in fully-differentiated cells plated on collagen-coated, transwell inserts. Interestingly, 59Fe uptake and efflux were impaired in both cell lines by Atp7a silencing. Concurrent changes in the expression of key iron transport-related genes were also noted in IEC-6 cells. Expression of Dmt1 (the iron importer), Dcytb (an apical membrane ferrireductase) and Fpn1 (the iron exporter) was decreased in Atp7a knockdown (KD) cells. Paradoxically, cell-surface ferrireductase activity increased (>5-fold) in Atp7a KD cells despite decreased Dcytb mRNA expression. Moreover, increased expression (>10-fold) of hephaestin (an iron oxidase involved in iron efflux) was associated with increased ferroxidase activity in KD cells. Increases in ferrireductase and ferroxidase activity may be compensatory responses to increase iron flux. In summary, in these reductionist models of the mammalian intestinal epithelium, Atp7a KD altered expression of iron transporters and impaired iron flux. Since Atp7a is a copper transporter, it is a logical supposition that perturbations in intracellular copper homeostasis underlie the noted biologic changes in these cell lines. PMID- 27714046 TI - Gap controlled plasmon-dielectric coupling effects investigated with single nanoparticle-terminated atomic force microscope probes. AB - Precise positioning of a plasmonic nanoparticle (NP) near a small dielectric surface is not only necessary for understanding gap-dependent interactions between a metal and dielectric but it is also a critical component in building ultrasensitive molecular rulers and force sensing devices. In this study we investigate the gap-dependent scattering of gold and silver NPs by controllably depositing them on an atomic force microscope (AFM) tip and monitoring their scattering within the evanescent field of a tin dioxide nanofiber waveguide. The enhanced distance-dependent scattering profiles due to plasmon-dielectric coupling effects show similar decays for both gold and silver NPs given the strong dependence of the coupling on the decaying power in the near-field. Experiments and simulations also demonstrate that the NPs attached to the AFM tips act as free NPs, eliminating optical interference typically observed from secondary dielectric substrates. With the ability to reproducibly place individual plasmonic NPs on an AFM tip, and optically monitor near-field plasmon dielectric coupling effects, this approach allows a wide-variety of light-matter interactions studies to be carried out on other low-dimensional nanomaterials. PMID- 27714047 TI - The role of carbon precursor on carbon nanotube chirality in floating catalyst chemical vapour deposition. AB - We have studied the influence of different carbon precursors (methane, ethanol and toluene) on the type, diameter and chiral angle distributions of carbon nanotubes (CNTs) grown with the floating catalyst technique in a horizontal gas flow reactor. Using electron diffraction to study their atomic structures, we found that ethanol and toluene precursors gave high single-wall CNT yields (92% and 89% respectively), with narrow diameter distributions: 1.1 nm to 1.7 nm (ethanol); 1.3 nm to 2.1 nm (toluene), with a propensity for armchair-type chiral angles. In contrast, methane-grown CNTs gave high double-wall CNT yields (75%) with broader diameter populations: 1.2 to 4.6 nm (inner CNT) and 2.2 to 5.3 nm (outer CNT) with a more uniform spread of chiral angles, but weakly peaked around 15 to 20 degrees. These observations agree with known growth models. However, double-wall CNTs grown with toluene showed an unusually narrow interlayer spacing of 0.286 +/- 0.003 nm with suggestions of large, 20 degrees to 25 degrees , differences between inner and outer CNT chiral angles. Methane gave a large interlayer spacing (0.385 +/- 0.002 nm) with suggestions of small 5 degrees to 10 degrees inter-tube chirality correlations. PMID- 27714045 TI - Mammalian Fe-S proteins: definition of a consensus motif recognized by the co chaperone HSC20. AB - Iron-sulfur (Fe-S) clusters are inorganic cofactors that are fundamental to several biological processes in all three kingdoms of life. In most organisms, Fe S clusters are initially assembled on a scaffold protein, ISCU, and subsequently transferred to target proteins or to intermediate carriers by a dedicated chaperone/co-chaperone system. The delivery of assembled Fe-S clusters to recipient proteins is a crucial step in the biogenesis of Fe-S proteins, and, in mammals, it relies on the activity of a multiprotein transfer complex that contains the chaperone HSPA9, the co-chaperone HSC20 and the scaffold ISCU. How the transfer complex efficiently engages recipient Fe-S target proteins involves specific protein interactions that are not fully understood. This mini review focuses on recent insights into the molecular mechanism of amino acid motif recognition and discrimination by the co-chaperone HSC20, which guides Fe-S cluster delivery. PMID- 27714048 TI - Skin-mountable stretch sensor for wearable health monitoring. AB - This work presents a wrinkled Platinum (wPt) strain sensor with tunable strain sensitivity for applications in wearable health monitoring. These stretchable sensors show a dynamic range of up to 185% strain and gauge factor (GF) of 42. This is believed to be the highest reported GF of any metal thin film strain sensor over a physiologically relevant dynamic range to date. Importantly, sensitivity and dynamic range are tunable to the application by adjusting wPt film thickness. Performance is reliable over 1000 cycles with low hysteresis after sensor conditioning. The possibility of using such a sensor for real-time respiratory monitoring by measuring chest wall displacement and correlating with lung volume is demonstrated. PMID- 27714049 TI - Flexible hierarchical membranes of WS2 nanosheets grown on graphene-wrapped electrospun carbon nanofibers as advanced anodes for highly reversible lithium storage. AB - It is still very challenging to achieve effective combination of carbon nanofibers and graphene sheets. In this study, a novel and facile method is developed to prepare flexible graphene/carbon nanofiber (GCNF) membranes with every carbon nanofiber wrapped by conductive graphene sheets, resulting in a remarkable improvement of their electrical conductivity. This method only entails a moderate process of soaking the pre-oxidized electrospun polyacrylonitrile (oPAN) nanofiber membranes in graphene oxide (GO) aqueous dispersion, and subsequent carbonization of the GO/oPAN hybrid membranes. By using the highly conductive GCNF membrane as a template, hierarchical WS2/GCNF hybrid membranes with few-layer WS2 nanosheets uniformly grown on GCNF nanofibers were fabricated as high-performance anodes for lithium ion batteries. Benefiting from the synergistic effects of GCNF nanofibers and WS2 nanosheets, the resulting WS2/GCNF hybrid membranes possessed a porous structure, large specific surface area, high electrical conductivity and good structural integrity, which are favorable for the rapid diffusion of lithium ions, fast transfer of electrons and overall electrochemical stability. As a result, the optimized WS2/GCNF hybrid membrane exhibited a high initial charge capacity of 1128.2 mA h g-1 at a current density of 0.1 A g-1 and outstanding cycling stability with 95% capacity retention after 100 cycles. PMID- 27714050 TI - Nonassociative learning implementation by a single memristor-based multi-terminal synaptic device. AB - Animals' survival is dependent on their abilities to adapt to the changing environment by adjusting their behaviours, which is related to the ubiquitous learning behaviour, nonassociative learning. Thus mimicking the indispensable learning behaviour in organisms based on electronic devices is vital to better achieve artificial neural networks and neuromorphic computing. Here a three terminal device consisting of an oxide-based memristor and a NMOS transistor is proposed. The memristor with gradual conductance tuning inherently functions as the synapse between sensor neurons and motor neurons and presents adjustable synaptic plasticity, while the NMOS transistor attached to the memristor is utilized to mimic the modulatory effect of the neuromodulator released by inter neurons. Such a memristor-based multi-terminal device allows the practical implementation of significant nonassociative learning based on a single electronic device. In this study, the experience-induced modification behaviour, both habituation and sensitization, was successfully achieved. The dependence of the nonassociative behavioural response on the strength and interval of presented stimuli was also discussed. The implementation of nonassociative learning offers feasible and experimental advantages for further study on neuromorphic systems based on electronic devices. PMID- 27714051 TI - Rational design of Pt-Ni-Co ternary alloy nanoframe crystals as highly efficient catalysts toward the alkaline hydrogen evolution reaction. AB - The rational design of highly efficient electrocatalysts for the hydrogen evolution reaction (HER) is of prime importance for establishing renewable and sustainable energy systems. The alkaline HER is particularly challenging as it involves a two-step reaction of water dissociation and hydrogen recombination, for which platinum-based binary catalysts have shown promising activity. In this work, we synthesized high performance platinum-nickel-cobalt alloy nanocatalysts for the alkaline HER through a simple synthetic route. This ternary nanostructure with a Cartesian-coordinate-like hexapod shape could be prepared by a one-step formation of core-dual shell Pt@Ni@Co nanostructures followed by a selective removal of the Ni@Co shell. The cobalt precursor brings about a significant impact on the control of size and shape of the nanostructure. The PtNiCo nanohexapods showed a superior alkaline HER activity to Pt/C and binary PtNi hexapods, with 10 times greater specific activity than Pt/C. In addition, the PtNiCo nanohexapods demonstrated excellent activity and durability for the oxygen reduction reaction in acidic media.

AB - MoSe2 nanosheets with small size and expanded spaces between the (002) planes were grown on the surfaces of porous N-doped carbon nanotubes (NCNTs) with much higher HER activity than carbon nanotubes without N dopants. Owing to the synergistic effects between the MoSe2 nanosheets and the porous NCNT substrate, MoSe2/NCNTs exhibit superior HER activity to layered metal chalcogenides reported previously. PMID- 27714053 TI - Decoupling the shape parameter to assess gold nanorod uptake by mammalian cells. AB - The impact of nanoparticles (NPs) upon biological systems can be fundamentally associated with their physicochemical parameters. A further often-stated tenet is the importance of NP shape on rates of endocytosis. However, given the convoluted parameters concerning the NP-cell interaction, it is experimentally challenging to attribute any findings to shape alone. Herein we demonstrate that shape, below a certain limit, which is specific to nanomedicine, is not important for the endocytosis of spherocylinders by either epithelial or macrophage cells in vitro. Through a systematic approach, we reshaped a single batch of gold nanorods into different aspect ratios resulting in near-spheres and studied their cytotoxicity, (pro-)inflammatory status, and endocytosis/exocytosis. It was found that on a length scale of ~10-90 nm and at aspect ratios less than 5, NP shape has little impact upon their entry into either macrophages or epithelial cells. Conversely, nanorods with an aspect ratio above 5 were preferentially endocytosed by epithelial cells, whereas there was a lack of shape dependent uptake following exposure to macrophages in vitro. These findings have implications both in the understanding of nanoparticle reshaping mechanisms, as well as in the future rational design of nanomaterials for biomedical applications. PMID- 27714054 TI - A flexible field-limited ordered ZnO nanorod-based self-powered tactile sensor array for electronic skin. AB - A tactile sensor is an essential component for realizing biomimetic robots, while the flexibility of the tactile sensor is a pivotal feature for its application, especially for electronic skin. In this work, a flexible self-powered tactile sensor array was designed based on the piezoelectricity of ZnO nanorods (NRs). The field-limited ordered ZnO NRs were synthesized on a flexible Kapton substrate to serve as the functional layer of the tactile sensor. The electrical output performances of the as-fabricated tactile sensor were measured under pressing and bending forces. Moreover, we measured the human-finger pressure detection performance of the tactile sensor array, suggesting that the corresponding mapping figure of finger pressure could be displayed on the monitor of a personal computer (PC) in the form of lighted LED and color density through a LabVIEW system. This as-grown sensory feedback system should be of potential valuable assistance for the users of hand prostheses to reduce the risk and obtain a greater feeling of using the prostheses. PMID- 27714055 TI - Strong dichroic emission in the pseudo one dimensional material ZrS3. AB - Zirconium trisulphide (ZrS3), a member of the layered transition metal trichalcogenides (TMTCs) family, has been studied by angle-resolved photoluminescence spectroscopy (ARPLS). The synthesized ZrS3 layers possess a pseudo one-dimensional nature where each layer consists of ZrS3 chains extending along the b-lattice direction. Our results show that the optical properties of few-layered ZrS3 are highly anisotropic as evidenced by large PL intensity variation with the polarization direction. Light is efficiently absorbed when the E-field is polarized along the chain (b-axis), but the field is greatly attenuated and absorption is reduced when it is polarized vertical to the 1D-like chains as the wavelength of the exciting light is much longer than the width of each 1D chain. The observed PL variation with polarization is similar to that of conventional 1D materials, i.e., nanowires, and nanotubes, except for the fact that here the 1D chains interact with each other giving rise to a unique linear dichroism response that falls between the 2D (planar) and 1D (chain) limit. These results not only mark the very first demonstration of PL polarization anisotropy in 2D systems, but also provide novel insight into how the interaction between adjacent 1D-like chains and the 2D nature of each layer influences the overall optical anisotropy of pseudo-1D materials. Results are anticipated to have an impact on optical technologies such as polarized detectors, near-field imaging, communication systems, and bio-applications relying on the generation and detection of polarized light.

AB - Magnetite nanoparticles combined with polymers produce white-light emission under multiphoton laser irradiation. Understanding the photonic reaction in magnetite polymer composites is critical for application of magnetite NPs as photothermal agents. Laser irradiated magnetite nanoparticle-poly(methyl methacrylate) (PMMA) composites exhibit fluorescence due to the carbon double-bond formation resulting from the oxidation of the PMMA. PMID- 27714057 TI - Rhodamine-doped nanoporous polymer films as high-performance anti-reflection coatings and optical filters. AB - We demonstrate a simple and robust procedure for the fabrication of rhodamine doped nanoporous poly(methyl methacrylate) (PMMA) films, whose optical properties, such as anti-reflection, fluorescence and absorption can be tailored to specific applications. By exploiting phase separation of a binary polymer blend (PMMA and polystyrene), we fabricated foam-like nanoporous films that could be easily and cost-effectively integrated into the fabrication process of optical components. We link film morphology, studied by multifrequency atomic force microscopy (AFM), to the effective refractive index of the films for use as anti reflection coatings. The film's morphology leads to superior broadband anti reflection performance compared with homogeneous films. For applications involving optical filters and spectral conversion layers (e.g., for photovoltaic applications), we doped the films with the fluorescent molecule rhodamine, whereby simple variations in the fabrication process enabled us to prepare rhodamine-doped nanoporous PMMA with tunable fluorescence and absorption, without losing the anti-reflective properties. The above combination of optical properties makes the films attractive for a wide range of applications. PMID- 27714058 TI - Self-adjusted all-dielectric metasurfaces for deep ultraviolet femtosecond pulse generation. AB - The advantage of metasurfaces and nanostructures with a high nonlinear response is that they do not require phase matching, and the generated pulses are short in the time domain without additional pulse compression. However, the fabrication of large-scale planar structures by lithography-based methods is expensive, time consuming, and requires complicated preliminary simulations to obtain the most optimized geometry. Here, we propose a novel strategy for the self-assembled fabrication of large-scale resonant metasurfaces, where incident femtosecond laser pulses adjust the initial silicon films via specific surface deformation to be as resonant as possible for a given wavelength. The self-adjusting approach eliminates the necessity of multistep lithography and designing, because interference between the incident and the scattered parts of each laser pulse "imprints" resonant field distribution within the film. The self-adjusted metasurfaces demonstrate a high damage threshold (~1012 W cm-2) and efficient frequency conversion from near-IR to deep UV. The conversion efficiency is up to 30-fold higher compared with nonresonant smooth Si films. The resulting metasurfaces allow for the generation of UV femtosecond laser pulses at a wavelength of 270 nm with a high peak and average power (~105 W and ~1.5 MUW, respectively). The results pave the way to the creation of ultrathin nonlinear metadevices working at high laser intensities for efficient deep UV generation at the nanoscale. PMID- 27714059 TI - In situ fabrication of Ni-Co (oxy)hydroxide nanowire-supported nanoflake arrays and their application in supercapacitors. AB - Three-dimensional (3D) hybrid nanostructured arrays grown on a flexible substrate have recently attracted great attention owing to their potential application as supercapacitor electrodes in portable and wearable electronic devices. Here, we report an in situ conversion of Ni-Co active electrode materials for the fabrication of high-performance electrodes. Ni-Co carbonate hydroxide nanowire arrays on carbon cloth were initially synthesized via a hydrothermal method, and they were gradually converted to Ni-Co (oxy)hydroxide nanowire-supported nanoflake arrays after soaking in an alkaline solution. The evolution of the supercapacitor performance of the soaked electrode was investigated in detail. The areal capacitance increases from 281 mF cm-2 at 1 mA cm-2 to 3710 and 3900 mF cm-2 after soaking for 36 h and 48 h, respectively. More interestingly, the electrode also shows an increased capacitance with charge/discharge cycles due to the long-time soaking in KOH solution, suggesting novel cycling durability. The enhancement in capacitive performance should be related to the formation of a unique nanowire-supported nanoflake array architecture, which controls the agglomeration of nanoflakes, making them fully activated. As a result, the facile in situ fabrication of the hybrid architectural design in this study provides a new approach to fabricate high-performance Ni/Co based hydroxide nanostructure arrays for next-generation energy storage devices. PMID- 27714060 TI - Serum metabolomics of Indian women with polycystic ovary syndrome using 1H NMR coupled with a pattern recognition approach. AB - Polycystic ovary syndrome (PCOS) is one of the most commonly occurring metabolic and endocrinological disorders affecting women of reproductive age. Metabolomics is an emerging field that holds promise in understanding disease pathophysiology. Recently, a few metabolomics based studies have been attempted in PCOS patients; however, none of them have included patients from the Indian population. The main objective of this study was to investigate the serum metabolomic profile of Indian women with PCOS and compare them with controls. Proton nuclear magnetic resonance (1H NMR) was used to first identify the differentially expressed metabolites among women with PCOS from the Eastern region of India during the discovery phase and further validated in a separate cohort of PCOS and control subjects. Multivariate analysis of the binned spectra indicated 16 dysregulated bins in the sera of these women with PCOS. Out of these 16 bins, 13 identified bins corresponded to 12 metabolites including 8 amino acids and 4 energy metabolites. Amongst the amino acids, alanine, valine, leucine and threonine and amongst the energy metabolites, lactate and acetate were observed to be significantly up-regulated in women with PCOS when compared with controls. The remaining 4 amino acids, l-glutamine, proline, glutamate and histidine were down regulated along with 2 energy metabolites: glucose and 3-hydroxybutyric acid. Our findings showed dysregulations in the expression of different metabolites in the serum of women with PCOS suggesting the involvement of multiple pathways including amino acid metabolism, carbohydrate/lipid metabolism, purine and pyrimidine metabolism and protein synthesis.

AB - Defects (Ti3+ or oxygen vacancies) have been demonstrated to promote the charge separation process in TiO2 based photocatalysts. Particularly, the bulk defects within a certain concentration can give a great enhancement for both light absorption and charge separation efficiency. In this report, we explored a one step molten salts route to synthesize SrTiO3 nanocubes with bulk defects (Ti3+ doped) by using SrCO3 as a Sr source, and TiO2 and Ti powder as Ti sources. The amount of defects can be tuned by changing the molar ratio of Ti/TiO2. The corresponding bandgap of SrTiO3 can be changed from 3.29 to 2.73 eV with the increase of defects. X-ray diffraction and electron microscopy disclose that SrTiO3 is highly crystalline and has a cubic morphology. X-ray photoelectron spectroscopy and electron paramagnetic resonance indicate that the as-prepared SrTiO3 is close to the Ti3+ doped SrTiO3. Surface photovoltage spectroscopy (SPS) and field-induced SPS confirm that Ti3+ doping in the SrTiO3 turns it from an n type semiconductor to p-type. The SrTiO3 with an optimal amount of defects exhibits highly enhanced photocatalytic performance. An excess amount of defects results in a weak SPS response and photocatalytic performance.

AB - We present an efficient strategy through surface functionalization to build a single silicon nanowire field-effect transistor-based biosensor that is capable of directly detecting protein adsorption/desorption at the single-event level. The step-wise signals in real-time detection of His-tag F1-ATPases demonstrate a promising electrical biosensing approach with single-molecule sensitivity, thus opening up new opportunities for studying single-molecule biophysics in broad biological systems. PMID- 27714063 TI - Analysis of the distribution of organic compounds and drugs between biological tissues in the framework of solute partitioning in aqueous two-phase systems. AB - Partition coefficients of non-ionic essentially nonpolar compounds between air and rat biological tissues and between blood and other tissues were examined and found to be linearly interrelated according to the previously established equation for partition coefficients of solutes in aqueous two-phase systems: log Kblood-tissue-1 = k0 + k1 log Kblood-tissue-2 + k2 log Kblood-tissue-3, where k0, k1, and k2 are constants. Analysis of partition coefficients of amphiphilic and ionizable drugs between blood and different tissues in rats in vivo showed that the above relationship holds for the blood-tissue partition coefficients of these compounds as well. The data obtained indicate that distribution of organic compounds between different biological tissues may be considered in the framework of solute partitioning in aqueous two-phase systems, and imply that aqueous media in different tissues have different solvent properties, and compound-water interactions in these media may respond to different environments governed by the tissue composition.

Rep., 2013, 30, 849 868The latest progress on the isolation, identification, biological activity and synthetic studies of the structurally diverse alkaloids from plants of family Amaryllidaceae has been summarized in this review. In addition, the structurally related alkaloids isolated from Sceletium species were discussed as well. PMID- 27714065 TI - Contact-dominated transport in carbon nanotube thin films: toward large-scale fabrication of high performance photovoltaic devices. AB - Semiconducting single-walled carbon nanotubes (s-SWCNTs) have been widely regarded as potential channel materials for not only replacing silicon to extend Moore's law but also for building high performance optoelectronic devices. To realize these goals, high quality s-SWCNTs and contacts are needed to outperform devices based on traditional materials such as silicon. For a high quality conducting or active channel, the ideal CNTs consist of a pure s-SWCNTs array with a confined pitch of less than 10 nm via e.g., chemical vapor deposition (CVD) methods, although this has not been realized experimentally. On the other hand, significant progress has been made on solution-processed CNTs. However, only network and low performance optoelectronic devices have been realized. In this study, we systematically studied the performance of devices using solution processed CNT films with different s-SWCNT purity, with particular emphasis being placed on disentangling those metallic-CNTs (m-CNTs)-dominated low performance and contacts-dominated high performance devices. We demonstrated that using high purity s-SWCNTs allowed for the construction of high performance diodes via a doping-free method. These diodes behave similarly to those based on individual CVD-grown s-CNTs, resulting in 250 mV photovoltage for a typical single diode and more than 4.35 V for cascading cells using the virtual contact technique and thus paving the way for large scale fabrication of higher performance photovoltaic devices using readily available solution processed CNTs. PMID- 27714066 TI - A nanoparticle-based thermo-dynamic aptasensor for small molecule detection. AB - Small molecules (MW < 1000 Da) represent a large class of biomarkers of interest. Recently, a new class of biosensors has been emerging thanks to the recognition properties of aptamers, short DNA or RNA single strands, selected against such small molecular targets. Among them, an adenosine-specific aptamer has been largely described and used due to its remarkable affinity to this small target (KD = 6 MUM). In this paper, we achieved the proof-of-principle of an aptasensor based on the thermodynamic follow-up of adenosine binding with engineered split aptamer sequences. The detection is carried out by surface plasmon resonance imaging of split-aptamer micro-arrays, while signal amplification is ensured by gold nanoparticles (AuNPs). This original approach based on DNA sequence engineering and AuNP conjugation enabled us to reach limits of detection (LOD) 200 times lower than the KD measured in solution with the native aptamer (LOD = 30 nM). PMID- 27714067 TI - Synthesis, self-assembly, and immunological activity of alpha-galactose functionalized dendron-lipid amphiphiles. AB - Nanoassemblies presenting multivalent displays of biologically active carbohydrates are of significant interest for a wide array of biomedical applications ranging from drug delivery to immunotherapy. In this study, glycodendron-lipid hybrids were developed as a new and tunable class of dendritic amphiphiles. A modular synthesis was used to prepare dendron-lipid hybrids comprising distearylglycerol and 0 through 4th generation polyester dendrons with peripheral protected amines. Following deprotection of the amines, an isothiocyanate derivative of C-linked alpha-galactose (alpha-Gal) was conjugated to the dendron peripheries, affording amphiphiles with 1 to 16 alpha-Gal moieties. Self-assembly in water through a solvent exchange process resulted in vesicles for the 0 through 2nd generation systems and micelles for the 3rd and 4th generation systems. The critical aggregation concentrations decreased with increasing dendron generation, suggesting that the effects of increasing molar mass dominated over the effects of increasing the hydrophilic weight fraction. The binding of the assemblies to Griffonia simplicifolia Lectin I (GSL 1), a protein with specificity for alpha-Gal was studied by quantifying the binding of fluorescently labeled assemblies to GSL 1-coated beads. It was found that binding was enhanced for amphiphiles containing higher generation dendrons. Despite their substantial structural differences with the natural ligands for the CD1d receptor, the glycodendron-lipid hybrids were capable of stimulating invariant natural killer T (iNKT) cells, a class of innate-like T cells that recognize lipid and glycolipid antigens presented by CD1d and that are implicated in a wide range of diseases and conditions including but not limited to infectious diseases, diabetes and cancer. PMID- 27714068 TI - A systems biology approach reveals new endoplasmic reticulum-associated targets for the correction of the ATP7B mutant causing Wilson disease. AB - Copper (Cu) is an important trace element required for the activity of essential enzymes. However, excess Cu compromises the redox balance in cells and tissues causing serious toxicity. The process of disposal of excess Cu from organisms relies on the activity of Cu-transporting ATPase ATP7B. ATP7B is mainly expressed in liver hepatocytes where it sequesters the potentially toxic metal and mediates its excretion into the bile. Mutations in the ATP7B gene cause Wilson disease (WD), which is characterized by the accumulation of toxic Cu in the liver due to the scarce expression of ATP7B as well as the failure of ATP7B mutants to pump Cu and/or traffic to the Cu-excretion sites. The most frequent ATP7B mutant, H1069Q, still presents a significant Cu-transporting activity, but undergoes retention within the endoplasmic reticulum (ER) where the mutant is rapidly degraded. Expression of this ATP7B mutant has been recently reported to activate the p38 and JNK stress kinase pathways, which, in turn, trigger quality control mechanisms leading to the arrest of ATP7B-H1069Q in the ER and to the acceleration of its degradation. However, the main molecular players operating in these p38/JNK-dependent ER quality control pathways remain to be discovered. By using a combination of RNAseq, bioinformatics and RNAi approaches, we found a cluster of ER quality control genes whose expression is controlled by p38 and JNK and is required for the efficient retention of the ATP7B-H1069Q mutant in the ER. Silencing these genes reduced the accumulation of the ATP7B mutant in the ER and facilitated the mutant sorting and export to the Golgi and post-Golgi copper excretion sites. In sum, our findings reveal the ER-associated genes that could be utilized for the correction of ATP7B mutants and, hence, for the normalization of Cu homeostasis in Wilson disease. PMID- 27714069 TI - Hidden symmetry of small spherical viruses and organization principles in "anomalous" and double-shelled capsid nanoassemblies. AB - We propose the principles of structural organization in spherical nanoassemblies with icosahedral symmetry constituted by asymmetric protein molecules. The approach modifies the paradigmatic geometrical Caspar and Klug (CK) model of icosahedral viral capsids and demonstrates the common origin of both the "anomalous" and conventional capsid structures. In contrast to all previous models of "anomalous" viral capsids the proposed modified model conserves the basic structural principles of the CK approach and reveals the common hidden symmetry underlying all small viral shells. We demonstrate the common genesis of the "anomalous" and conventional capsids and explain their structures in the same frame. The organization principles are derived from the group theory analysis of the positional order on the spherical surface. The relationship between the modified CK geometrical model and the theory of two-dimensional spherical crystallization is discussed. We also apply the proposed approach to complex double-shelled capsids and capsids with protruding knob-like proteins. The introduced notion of commensurability for the concentric nanoshells explains the peculiarities of their organization and helps to predict analogous, but yet undiscovered, double-shelled viral capsid nanostructures. PMID- 27714070 TI - CuGaS2-ZnS p-n nanoheterostructures: a promising visible light photo-catalyst for water-splitting hydrogen production. AB - In this work, novel CuGaS2-ZnS p-n type semiconductor nanoheterostructures were synthesized by a solution route, and demonstrated experimentally to be a very promising visible light active photo-catalyst for water-splitting hydrogen production. The construction of CuGaS2-ZnS heterostructures follows a multi-step strategy, employing Cu1.94S nanocrystals first as catalytic assistants for the hetero-growth of ZnS on their surfaces, and then as sacrificial seeds for the formation of CuGaS2. Excitingly, attributed to the efficient charge separation introduced by the p-n heterojunctions, the hydrogen production ability of the CuGaS2-ZnS nanoheterostructures under visible light irradiation is 15 times higher than that of the CuGaS2 component, and comparable to that of the CdS nanophase which is currently regarded as one of the most active visible photo catalysts for hydrogen generation. PMID- 27714071 TI - Artificial hydrolase based on carbon nanotubes conjugated with peptides. AB - An artificial enzyme was constructed by attaching short peptides with active sites (SHELKLKLKL, WLKLKLKL) onto carbon nanotubes (CNT). It was found that the combination of SHE amino acids was essential to form a catalytic triad. W was also incorporated into this artificial enzyme and acted as a substrate binding site, thus producing an enzyme model with synergism of 67.7% catalytic groups and 32.3% binding groups, CNT-(SHE/W)2:1-LKLKLKL. When the peptide SHELKLKLKL was attached with the catalytic triad site close to the surface of CNT, the composite had higher activity than a leucine-attached system terminated with the catalytic triad site, suggesting that CNT not only served as a platform for attaching active amino acids, but also created a hydrophobic microenvironment and facilitated the proton transfer process to enhance the catalytic activity. The artificial enzyme exhibited Michaelis-Menten behaviour, indicating that it was indeed a mimic of the corresponding natural enzyme. This work showed that a well designed combination of CNT and short peptides containing active sites can mimic a natural enzyme. PMID- 27714072 TI - Dynamic visualization of photothermal heating by gold nanocages using thermoresponsive elastin like polypeptides. AB - Understanding how plasmonic nanoparticles collectively generate heat upon exposure to light and thus increase the local temperature of the surrounding medium is critical for many applications such as plasmon-assisted microfluidics, plasmonic tweezers, and photothermal cancer therapy. Reliable temperature manipulation requires the capability to spatially and dynamically analyze local temperature profiles as a function of nanoparticle concentration and laser intensity. In this work, we present a novel method for visualization of local temperature increase using elastin-like polypeptides (ELP). We also propose a robust algorithm that allows the construction of reliable calibration curves using known boundary conditions and Boltzmann sigmoid fit applied to the ELP solution's temperature-absorption transfer function. Using this technique, for the first time, we successfully demonstrated how surface and volume distribution of the nano-heaters affect collective heat generation. This approach allows the visualization of dynamic 2D-temperature profiles and simultaneously enables the measurement of specific temperature at any point in a 2D-map. The experimental setup is compatible with conventional optical microscopy and requires no specialized hardware or complex sample preparation. Finally, the real time visualization of plasmonic heating offers an opportunity to control outcomes of thermo-plasmonics which enables a myriad of practical applications. PMID- 27714073 TI - Constructing bifunctional nanoparticles for dual targeting: improved grafting and surface recognition assessment of multiple ligand nanoparticles. AB - Nanoparticles (NPs) functionalized with two active targeting ligands have been proposed in drug delivery for their promising capability to stimulate different pathways with one object. Due to the multivalency, the construction and analysis of the effective surface of such bifunctional nanoparticles, however, is significantly more complex than for nanoparticles bearing only one ligand. Here, we optimize construction and analysis of bifunctional NPs containing recognizable combinations of human serum albumin (HSA), transferrin (Tf), and epidermal growth factor (EGF) on fluorescent silica NPs grafted via common polyethylene glycol (PEG) linkers as a model system. Combined with an overall protein quantification, a mapping of exposed recognizable sequences using monoclonal antibodies conjugated to gold nanoparticles (AuNPs) or quantum dots (QDs) for enhanced spectroscopic and microscopic detection revealed that active protein sequences can be one to two orders of magnitude lower than overall conjugated proteins while possessing specific cellular recognition. In addition, we found that common conjugation strategies lead to a large excess of non-specifically compared to covalently bound ligands and instabilities that may impact targeting. These can be avoided by certain synthetic conditions presented here for effective exploitation of multivalent surfaces in nanomedicine. PMID- 27714074 TI - miR-186 regulates chemo-sensitivity to paclitaxel via targeting MAPT in non-small cell lung cancer (NSCLC). AB - miR-186 has been reported to be implicated in tumorigenesis and chemoresistance in a few cancer types. However, its role in regulating chemoresistance has not been investigated in non-small cell lung cancer (NSCLC). To examine the effects of miR-186 on chemosensitivity in NSCLC, an miR-186 mimic and inhibitor were transfected, followed by CellTiter-Glo(r) assay in NSCLC cell lines. Western blot and luciferase assay were performed to investigate the direct targeting of miR 186. A xenograft mouse model was used to examine the in vivo chemosensitizing function of miR-186. We found that overexpression of miR-186 sensitized A549 and H1299 cells to paclitaxel, whereas inhibition of miR-186 conferred resistance in these cells. MAPT was the direct target of miR-186 which was required for the regulatory role of miR-186 in chemoresistance. This chemosensitizing function was partially due to the induction of the p53 mediated apoptotic pathway. The miR-186 mimic enhanced the tumor growth inhibitory effects of paclitaxel in A549 xenografts. In addition, miR-186 was found to be down-regulated in NSCLC patients who were chemoresistant and this down-regulation was associated with poor survival. Taken together, our study demonstrated that miR-186 regulates the chemoresistance of NSCLC cells by modulating the MAPT expression level both in vitro and in vivo. miR-186 may represent a new therapeutic target for the improvement of the clinical outcome in NSCLC.

PMID- 27714076 TI - Nanoengineering neural stem cells on biomimetic substrates using magnetofection technology. AB - Tissue engineering studies are witnessing a major paradigm shift to cell culture on biomimetic materials that replicate native tissue features from which the cells are derived. Few studies have been performed in this regard for neural cells, particularly in nanomedicine. For example, platforms such as magnetic nanoparticles (MNPs) have proven efficient as multifunctional tools for cell tracking and genetic engineering of neural transplant populations. However, as far as we are aware, all current studies have been conducted using neural cells propagated on non-neuromimetic substrates that fail to represent the mechano elastic properties of brain and spinal cord microenvironments. Accordingly, it can be predicted that such data is of less translational and physiological relevance than that derived from cells grown in neuromimetic environments. Therefore, we have performed the first test of magnetofection technology (enhancing MNP delivery using applied magnetic fields with significant potential for therapeutic application) and its utility in genetically engineering neural stem cells (NSCs; a population of high clinical relevance) propagated in biomimetic hydrogels. We demonstrate magnetic field application safely enhances MNP mediated transfection of NSCs grown as 3D spheroid structures in collagen which more closely replicates the intrinsic mechanical and structural properties of neural tissue than routinely used hard substrates. Further, as it is well known that MNP uptake is mediated by endocytosis we also investigated NSC membrane activity grown on both soft and hard substrates. Using high resolution scanning electron microscopy we were able to prove that NSCs display lower levels of membrane activity on soft substrates compared to hard, a finding which could have particular impact on MNP mediated engineering strategies of cells propagated in physiologically relevant systems. PMID- 27714077 TI - Monolayer graphene sensing enabled by the strong Fano-resonant metasurface. AB - Recent advances in graphene photonics reveal promising applications in the technologically important terahertz spectrum, where graphene-based active terahertz metamaterial modulators have been experimentally demonstrated. However, the sensitivity of the atomically thin graphene monolayer towards sharp Fano resonant terahertz metasurfaces remains unexplored. Here, we demonstrate thin film sensing of the graphene monolayer with a high quality factor terahertz Fano resonance in metasurfaces consisting of a two-dimensional array of asymmetric resonators. A drastic change in the transmission amplitude of the Fano resonance was observed due to strong interactions between the monolayer graphene and the tightly confined electric fields in the capacitive gaps of the Fano resonator. The deep-subwavelength sensing of the atomically thin monolayer graphene further highlights the extreme sensitivity of the resonant electric field excited at the dark Fano resonance, allowing the detection of an analyte that is lambda/1 000 000 thinner than the free space wavelength.

AB - Covering: 2005 to 2016Clavosolides A-D and cyanolide A are glycosidic macrolides and represent a new family of marine natural products. They possess a number of unusual structural features and have attracted considerable interest from the synthetic community. This review presents a comprehensive survey of all aspects of the clavosolides A-D and cyanolide A. Specific topics include isolation, structure determination, biological activity, and synthetic approaches. PMID- 27714079 TI - High-performance flexible ZnO nanorod UV photodetectors with a network-structured Cu nanowire electrode. AB - In this work, vertically aligned zinc oxide (ZnO) nanorod (NR)-based flexible ultraviolet (UV) photodetectors were successfully fabricated on a polyimide (PI) substrate with a copper (Cu) nanowire (NW) electrode. To enhance the flexibility and sensing properties, the entangled networks of Cu NWs were applied to UV photodetectors as a flexible electrode. Here, Cu NWs have a high conductivity with a low cost compared to other metals to achieve a Schottky contact with ZnO NRs. Moreover, because of forming a network structure, the surface of the sensing material has a large contact area with oxygen molecules, resulting in a faster response time. The Cu NW electrode exhibited a high optical transmittance of 90%, a considerable sheet resistance of 50 Omega sq-1, and a work function of 5.12 eV. Consequentially, the fabricated UV photodetector with Cu NW electrodes showed excellent UV sensing properties with a very fast rising time of 0.7 s and a decay time of 1.9 s in the dark and under UV illumination (365 nm, 0.40 mW cm-2) at a reverse bias of -2.0 V. Furthermore, during the bending test at a radius of curvature of 5 mm, the flexible ZnO NR UV photodetectors with Cu NW electrodes exhibited almost unchanged UV sensing properties even after 5000 cycles.

AB - We report the tracking of atom count in individual nanoparticles during photochemical Ostwald ripening. The nano-impact technique, in conjunction with UV Vis and TEM analysis, is used to follow the photochemical formation of silver nano-prisms from spherical seed particles. A mechanism of photochemical Ostwald ripening is deduced and key growth stages are identified. PMID- 27714081 TI - Protein clustering in chemically stressed HeLa cells studied by infrared nanospectroscopy. AB - Photo-Thermal Induced Resonance (PTIR) nanospectroscopy, tuned towards amide-I absorption, was used to study the distribution of proteic material in 34 different HeLa cells, of which 18 were chemically stressed by oxidative stress with Na3AsO3. The cell nucleus was found to provide a weaker amide-I signal than the surrounding cytoplasm, while the strongest PTIR signal comes from the perinuclear region. AFM topography shows that the cells exposed to oxidative stress undergo a volume reduction with respect to the control cells, through an accumulation of the proteic material around and above the nucleus. This is confirmed by the PTIR maps of the cytoplasm, where the pixels providing a high amide-I signal were identified with a space resolution of ~300 * 300 nm. By analyzing their distribution with two different statistical procedures we found that the probability to find protein clusters smaller than 0.6 MUm in the cytoplasm of stressed HeLa cells is higher by 35% than in the control cells. These results indicate that it is possible to study proteic clustering within single cells by label-free optical nanospectroscopy. PMID- 27714082 TI - A redox-responsive mesoporous silica nanoparticle with a therapeutic peptide shell for tumor targeting synergistic therapy. AB - In this study, we report a novel redox-responsive mesoporous silica nanoparticle (MSN)-based nanocarrier, capping with a therapeutic peptide ((RGDWWW)2KC) containing a RGD target motif, for tumor targeting synergistic therapy, which is designated as TTSTMSN. The MSN was decorated with a tumor-targeting therapeutic peptide as a potential gatekeeper. The two branched peptides containing rich tryptophans allowed the pores to be blocked via pi-pi stacking and hydrophobic interactions. Once the drug loaded nanoparticles were taken up by the cancer cells through integrin-mediated endocytosis, the therapeutic peptide capping shells on the surface of MSNs were released, inducing the loaded drug to diffuse into the cytoplasm after breaking of the disulfide bonds, triggered by the high concentration of glutathione (GSH) in cancer cells. At the same time, the falling therapeutic rich tryptophans in the branched chains interacted with DNA due to the indole rings, leading to disturbance of the DNA structure through the strong pi interactions and causing cell apoptosis. There is no such report on capping of drug loaded porous silica with a therapeutic peptide shell, co-delivering an anticancer drug and therapeutic agent for tumor targeting synergistic therapy, which will have great potential in developing multifunctional nanocarriers based on therapeutic peptides for synergistic treatment. PMID- 27714083 TI - Hydrogen bonding vs. molecule-surface interactions in 2D self-assembly of [C60]fullerenecarboxylic acids. AB - The adsorption of C60-malonic derivatives C61(CO2H)2 and C66(CO2H)12 on Au(111) and a pentafluorobenzenethiol-modified Au substrate (PFBT@Au) has been investigated using scanning tunneling microscopy (STM) at a liquid-solid interface. Monofunctionalized C61(CO2H)2 forms a hexagonal close-packed overlayer on Au(111) and individual aligned dimers on PFBT@Au(111). The difference is attributed to the nature of the substrateC61(CO2H)2 interaction (isotropic pi-Au bonding vs. anisotropic PFBTCOOH interactions). Surprisingly, in both cases, the directionality of the COOHCOOH motif is compromised in favor of synergistic van der Waals/H bonding interactions. Such van der Waals contacts are geometrically unfeasible in hexafunctionalized C66(CO2H)12 and its assembly on Au(111) leads to a 2D molecular network controlled exclusively by H bonding. For both molecules, the "free" CO2H groups on the monolayer surface can engage in out-of-plane H bonding interaction resulting in the epitaxial growth of subsequent molecular layers.

PMID- 27714085 TI - Solid-state colloidal CuInS2 quantum dot solar cells enabled by bulk heterojunctions. AB - Colloidal copper indium sulfide (CIS) nanocrystals (NCs) are Pb- and Cd-free alternatives for use as absorbers in quantum dot solar cells. In a heterojunction with TiO2, non-annealed ligand-exchanged CIS NCs form solar cells yielding a meager power conversion efficiency (PCE) of 0.15%, with photocurrents plummeting far below predicted values from absorption. Decreasing the amount of zinc during post-treatment leads to improved mobility but marginal improvement in device performance (PCE = 0.30%). By incorporating CIS into a porous TiO2 network, we saw an overall drastic improvement in device performance, reaching a PCE of 1.16%, mainly from an increase in short circuit current density (Jsc) and fill factor (FF) and a 10-fold increase in internal quantum efficiency (IQE). We have determined that by moving from a bilayer to a bulk heterojunction architecture, we have reduced the trap-assisted recombination as seen in changes in the ideality factor, the intensity dependence of the photocurrent and transient photocurrent (TPC) and photovoltage (TPV) characteristics. PMID- 27714086 TI - 1D Ni-Co oxide and sulfide nanoarray/carbon aerogel hybrid nanostructures for asymmetric supercapacitors with high energy density and excellent cycling stability. AB - The fabrication of supercapacitor electrodes with high energy density and excellent cycling stability is still a great challenge. A carbon aerogel, possessing a hierarchical porous structure, high specific surface area and electrical conductivity, is an ideal backbone to support transition metal oxides and bring hope to prepare electrodes with high energy density and excellent cycling stability. Therefore, NiCo2S4 nanotube array/carbon aerogel and NiCo2O4 nanoneedle array/carbon aerogel hybrid supercapacitor electrode materials were synthesized by assembling Ni-Co precursor needle arrays on the surface of the channel walls of hierarchical porous carbon aerogels derived from chitosan in this study. The 1D nanostructures grow on the channel surface of the carbon aerogel vertically and tightly, contributing to the enhanced electrochemical performance with ultrahigh energy density. The energy density of NiCo2S4 nanotube array/carbon aerogel and NiCo2O4 nanoneedle array/carbon aerogel hybrid asymmetric supercapacitors can reach up to 55.3 Wh kg-1 and 47.5 Wh kg-1 at a power density of 400 W kg-1, respectively. These asymmetric devices also displayed excellent cycling stability with a capacitance retention of about 96.6% and 92% over 5000 cycles.

AB - The research and development of advanced energy-storage systems must meet a large number of requirements, including high energy density, natural abundance of the raw material, low cost and environmental friendliness, and particularly reasonable safety. As the demands of high-performance batteries are continuously increasing, with large-scale energy storage systems and electric mobility equipment, lithium-sulfur batteries have become an attractive candidate for the new generation of high-performance batteries due to their high theoretical capacity (1675 mA h g-1) and energy density (2600 Wh kg-1). However, rapid capacity attenuation with poor cycle and rate performances make the batteries far from ideal with respect to real commercial applications. Outstanding breakthroughs and achievements have been made to alleviate these problems in the past ten years. This paper presents an overview of recent advances in lithium sulfur battery research. We cover the research and development to date on various components of lithium-sulfur batteries, including cathodes, binders, separators, electrolytes, anodes, collectors, and some novel cell configurations. The current trends in materials selection for batteries are reviewed and various choices of cathode, binder, electrolyte, separator, anode, and collector materials are discussed. The current challenges associated with the use of batteries and their materials selection are listed and future perspectives for this class of battery are also discussed. PMID- 27714088 TI - An ultrasensitive SERS sensor for simultaneous detection of multiple cancer related miRNAs. AB - Simultaneous detection of multiple trace cancer associated serum miRNA biomarkers is considered as a feasible method for early cancer screening and diagnosis. In the present work, an ultrasensitive SERS sensor was prepared based on an Ag nanorod array SERS substrate by assembling special hairpin-shaped molecular beacons (MBs) for the detection of multiple lung cancer-related miRNA biomarkers. The portable SERS sensor exhibits excellent performance for the qualitative and quantitative detection of miRNAs, with advantages of ultra-sensitivity, good specificity, uniformity, reproducibility and stability, as well as remarkable reusability. By monitoring the SERS signal quenching of the MBs in the presence of target miRNA biomarkers, three lung cancer related-miRNAs (miRNA-21, miRNA 486, and miRNA-375) in buffer and human serum were simultaneously assayed using the SERS sensor array, and the limits of detection of the three miRNAs in human serum are 393 aM, 176 aM, and 144 aM, respectively. The reliable results demonstrate that the proposed SERS sensor array can be a promising candidate with great potential for the screening and clinical diagnosis of cancer in the early stage. PMID- 27714089 TI - Field emission and anode etching during formation of length-controlled nanogaps in electrical breakdown of horizontally aligned single-walled carbon nanotubes. AB - We observe field emission between nanogaps and voltage-driven gap extension of single-walled carbon nanotubes (SWNTs) on substrates during the electrical breakdown process. Experimental results show that the gap size is dependent on the applied voltage and humidity, which indicates high controllability of the gap size by appropriate adjustment of these parameters in accordance with the application. We propose a mechanism for the gap formation during electrical breakdown as follows. After small gaps are formed by Joule heating-induced oxidation, SWNTs on the anode side are electrochemically etched due to physically adsorbed water from the air and the enhanced electric field at the SWNT tips. Field emission is measured in a vacuum as a possible mechanism for charge transfer at SWNT gaps. The relationship between the field enhancement factor and geometric features of SWNTs explains both the voltage dependence of the extended gap size and the field emission properties of the SWNT gaps. In addition, the similar field-induced etching can cause damage to adjacent SWNTs, which possibly deteriorates the selectivity for cutting metallic pathways in the presence of water vapor.

AB - Here we present the Mendeleev-Meyer Force Project which aims at tabulating all materials and substances in a fashion similar to the periodic table. The goal is to group and tabulate substances using nanoscale force footprints rather than atomic number or electronic configuration as in the periodic table. The process is divided into: (1) acquiring nanoscale force data from materials, (2) parameterizing the raw data into standardized input features to generate a library, (3) feeding the standardized library into an algorithm to generate, enhance or exploit a model to identify a material or property. We propose producing databases mimicking the Materials Genome Initiative, the Medical Literature Analysis and Retrieval System Online (MEDLARS) or the PRoteomics IDEntifications database (PRIDE) and making these searchable online via search engines mimicking Pubmed or the PRIDE web interface. A prototype exploiting deep learning algorithms, i.e. multilayer neural networks, is presented.

AB - This study was designed to assess the efficacy of hyaluronan (HA) functionalized well-aligned nanofibers of poly-l-lactic acid (PLLA) in modulating the phenotypic expression of vascular smooth muscle cells (vSMCs) for blood vessel regeneration. Highly aligned HA/PLLA nanofibers in core-shell structure were prepared using a novel stable jet electrospinning approach. Formation of a thin HA-coating layer atop each PLLA nanofiber surface endowed the uni-directionally oriented fibrous mats with increased anisotropic wettability and mechanical compliance. The HA/PLLA nanofibers significantly promoted vSMC to elongation, orientation, and proliferation, and also up-regulated the expression of contractile genes/proteins (e.g., alpha-SMA, SM-MHC) as well as the synthesis of elastin. Six weeks of in vivo scaffold replacement of rabbit carotid arteries showed that vascular conduits made of circumferentially aligned HA/PLLA nanofibers could maintain patency and promoted oriented vSMC regeneration, lumen endothelialization, and capillary formation. This study demonstrated the synergistic effects of nanotopographical and biochemical cues in one biomimetic scaffold design for efficacious vascular regeneration. PMID- 27714092 TI - Magnesium ions in yeast: setting free the metabolism from glucose catabolite repression. AB - In a recent work we showed that magnesium (MgII) plays an important role in industrial ethanol production, overcoming the negative effect of the excess of minerals, particularly copper, present in sugarcane juice, with a consequent increase in ethanol yield. This cation has been reported to be involved in several steps of yeast metabolism, acting mainly as a co-factor of several enzymes of fermentation metabolism and protecting yeast cells from stressful conditions. However, despite many physiological investigations, its effect in the molecular mechanisms that control such metabolic activities remains unclear and to date no information concerning its influence on gene expression has been provided. The present work took advantage of the DNA microarray technology to analyse the global gene expression in yeast cells upon fermentation in MgII supplemented medium. The results of the fermentation parameters confirmed the previous report on the increase in ethanol yield by MgII. Moreover, the gene expression data revealed an unexpected set of up-regulated genes currently assigned as being negatively-regulated by glucose, which belong to respiratory and energy metabolism, the stress response and the glyoxalate cycle. On the other hand, genes involved in ribosome biogenesis were down-regulated. Computational analysis provided evidence for a regulatory network commanded by key transcriptional factors that may be responsible for the biological action of MgII in yeast cells. In this scenario, MgII seems to act by reprogramming the yeast metabolism by releasing many genes from glucose catabolite repression with positive consequences for ethanol production and maintenance of cell viability.

AB - Carbon dot and BiVO4 quantum dot composites (CDs/BiVO4 QDs) show a significantly improved photocatalytic activity and high stability for overall water splitting. By using 5% CDs/BiVO4 QDs as photocatalysts, the H2 evolution of 0.92 MUmol h-1, was achieved under solar light irradiation without any cocatalysts or sacrificial reagents, which is about 4 times that of BiVO4 QDs (0.21 MUmol h-1). Note that, for the CD/BiVO4 QD catalyst, the produced H2 and O2 are approximately equal to the stoichiometric ratio (H2 : O2 = 1.80 : 1), while that of BiVO4 QDs is nonstoichiometric (about only 0.06 : 1). In addition, the present water splitting occurs via a two-electron pathway and CDs and BiVO4 QDs served as the reduction and oxidation reaction active sites, respectively. PMID- 27714094 TI - Skin inspired fractal strain sensors using a copper nanowire and graphite microflake hybrid conductive network. AB - This work demonstrates a facile "paint-on" approach to fabricate highly stretchable and highly sensitive strain sensors by combining one-dimensional copper nanowire networks with two-dimensional graphite microflakes. This paint-on approach allows for the fabrication of electronic skin (e-skin) patches which can directly replicate with high fidelity the human skin surface they are on, regardless of the topological complexity. This leads to high accuracy for detecting biometric signals for applications in personalised wearable sensors. The copper nanowires contribute to high stretchability and the graphite flakes offer high sensitivity, and their hybrid coating offers the advantages of both. To understand the topological effects on the sensing performance, we utilized fractal shaped elastomeric substrates and systematically compared their stretchability and sensitivity. We could achieve a high stretchability of up to 600% and a maximum gauge factor of 3000. Our simple yet efficient paint-on approach enabled facile fine-tuning of sensitivity/stretchability simply by adjusting ratios of 1D vs. 2D materials in the hybrid coating, and the topological structural designs. This capability leads to a wide range of biomedical sensors demonstrated here, including pulse sensors, prosthetic hands, and a wireless ankle motion sensor. PMID- 27714095 TI - Charge transfer in crystalline germanium/monolayer MoS2 heterostructures prepared by chemical vapor deposition. AB - Heterostructuring provides novel opportunities for exploring emergent phenomena and applications by developing designed properties beyond those of homogeneous materials. Advances in nanoscience enable the preparation of heterostructures formed incommensurate materials. Two-dimensional (2D) materials, such as graphene and transition metal dichalcogenides, are of particular interest due to their distinct physical characteristics. Recently, 2D/2D heterostructures have opened up new research areas. However, other heterostructures such as 2D/three dimensional (3D) materials have not been thoroughly studied yet although the growth of 3D materials on 2D materials creating 2D/3D heterostructures with exceptional carrier transport properties has been reported. Here we report a novel heterostructure composed of Ge and monolayer MoS2, prepared by chemical vapor deposition. A single crystalline Ge (110) thin film was grown on monolayer MoS2. The electrical characteristics of Ge and MoS2 in the Ge/MoS2 heterostructure were remarkably different from those of isolated Ge and MoS2. The field-effect conductivity type of the monolayer MoS2 is converted from n-type to p-type by growth of the Ge thin film on top of it. Undoped Ge on MoS2 is highly conducting. The observations can be explained by charge transfer in the heterostructure as opposed to chemical doping via the incorporation of impurities, based on our first-principles calculations. PMID- 27714096 TI - Tunable nanoblock lasers and stretching sensors. AB - Reconfigurable, reliable, and robust nanolasers with wavelengths tunable in the telecommunication bands are currently being sought after for use as flexible light sources in photonic integrated circuits. Here, we propose and demonstrate tunable nanolasers based on 1D nanoblocks embedded within stretchable polydimethylsiloxane. Our lasers show a large wavelength tunability of 7.65 nm per 1% elongation. Moreover, this tunability is reconfigurable and reliable under repeated stretching/relaxation tests. By applying excessive stretching, wide wavelength tuning over a range of 80 nm (spanning the S, C, and L telecommunication bands) is successfully demonstrated. Furthermore, as a stretching sensor, an enhanced wavelength response to elongation of 9.9 nm per % is obtained via the signal differential from two nanoblock lasers positioned perpendicular to each other. The minimum detectable elongation is as small as 0.056%. Nanoblock lasers can function as reliable tunable light sources in telecommunications and highly sensitive on-chip structural deformation sensors. PMID- 27714097 TI - Standalone anion- and co-doped titanium dioxide nanotubes for photocatalytic and photoelectrochemical solar-to-fuel conversion. AB - Several strategies are currently being investigated for conversion of incident sunlight into renewable sources of energy, and photocatalytic or photoelectrochemical production of solar fuels can provide an important alternative. Titanium dioxide (TiO2) has been heavily investigated as a material of choice due to its excellent optoelectronic properties and stability, and anion doping proposed as a pathway to improve light absorption as well as improving the efficiency of oxygen production. While several studies have used morphological tuning, elemental doping, and surface engineering in TiO2 to extend its absorption, there is a need to optimize simultaneously charge transport and improve interfacial chemical reaction kinetics. Here we show anion-doped (nitrogen, carbon) standalone TiO2 nanotube membranes that absorb visible light for the water-splitting reaction, using both wireless (photocatalysis) and wired (photoelectrochemical) solar-to-fuel conversion (STFC) cells. Using simulated solar radiation, we show generation of hydrogen as a solar fuel using visible light photocatalysis. Furthermore, using a model we elucidate detailed photophysics and photoelectrochemical properties of these nanotubes, and explain the kinetics of photogenerated charge carriers following light absorption. We show that while visible light induces a superlinear photoresponse for catalytic reduction and may benefit from higher incident light intensity, ultraviolet light shows a linear photoresponse and saturation with higher light flux due to trapping of photogenerated charges (mainly electrons). These results can have important implications for design of other metal-oxide membranes for solar fuel generation, and appropriate design of dopants and induced energy levels in these photocatalysts. PMID- 27714098 TI - Tuning the Fermi-level of TiO2 mesoporous layer by lanthanum doping towards efficient perovskite solar cells. AB - Tuning the band alignment is proved to be an effective way to facilitate carrier transportation and thus enhance the power conversion efficiency (PCE) of solar cells. Doping the compact layer with metal ions or modifying the interfaces among functional layers in perovskite solar cells (PSCs) can appreciably improve the PCE of PSCs. Inspired by the rare earth elemental doping of TiO2, which has witnessed the success in photocatalysis and dye-sensitized solar cells, we firstly demonstrated here that La3+ doping in the mesoporous TiO2 layer of a mesostructured PSC can tune its Fermi level and thus significantly enhance the device PCE. Systematic analysis reveals that doping La3+ into TiO2 raises the Fermi level of TiO2 through scavenging oxygen and inducing vacancies, which subsequently increases the open circuit voltage and the fill factor while reducing the series resistance of the PSC using La3+-doped TiO2 as a mesoporous layer. As a result, a PCE of 15.42% is achieved, which is appreciably higher than the PCE of a device with undoped TiO2 (12.11%). PMID- 27714099 TI - Three-dimensional (3D) plasmonic hot spots for label-free sensing and effective photothermal killing of multiple drug resistant superbugs. AB - Drug resistant superbug infection is one of the foremost threats to human health. Plasmonic nanoparticles can be used for ultrasensitive bio-imaging and photothermal killing by amplification of electromagnetic fields at nanoscale "hot spots". One of the main challenges to plasmonic imaging and photothermal killing is design of a plasmonic substrate with a large number of "hot spots". Driven by this need, this article reports design of a three-dimensional (3D) plasmonic "hot spot"-based substrate using gold nanoparticle attached hybrid graphene oxide (GO), free from the traditional 2D limitations. Experimental results show that the 3D substrate has capability for highly sensitive label-free sensing and generates high photothermal heat. Reported data using p-aminothiophenol conjugated 3D substrate show that the surface enhanced Raman spectroscopy (SERS) enhancement factor for the 3D "hot spot"-based substrate is more than two orders of magnitude greater than that for the two-dimensional (2D) substrate and five orders of magnitude greater than that for the zero-dimensional (0D) p aminothiophenol conjugated gold nanoparticle. 3D-Finite-Difference Time-Domain (3D-FDTD) simulation calculations indicate that the SERS enhancement factor can be greater than 104 because of the bent assembly structure in the 3D substrate. Results demonstrate that the 3D-substrate-based SERS can be used for fingerprint identification of several multi-drug resistant superbugs with detection limits of 5 colony forming units per mL. Experimental data show that 785 nm near infrared (NIR) light generates around two times more photothermal heat for the 3D substrate with respect to the 2D substrate, and allows rapid and effective killing of 100% of the multi-drug resistant superbugs within 5 minutes. PMID- 27714100 TI - Ordered gyroidal tantalum oxide photocatalysts: eliminating diffusion limitations and tuning surface barriers. AB - In this work we synthesized well-ordered, Ta2O5 films with a 3D-interconnected gyroid mesopore architecture with large pore sizes beyond 30 nm and extended crystalline domains through self-assembly of tailor-made triblock-terpolymers. This has effectively eliminated diffusion limitations inherent to previously reported mesoporous photocatalysts and resulted in superior hydrogen evolution with apparent quantum yields of up to 4.6% in the absence of any cocatalyst. We further show that the injection barrier at the solid-liquid interface constitutes a key criterion for photocatalytic performance and can be modified by the choice of the carbon template. This work highlights pore and surface engineering as a promising tool towards high-performance mesoporous catalysts and electrodes for various energy-related applications. PMID- 27714101 TI - Fractal growth of platinum electrodeposits revealed by in situ electron microscopy. AB - Fractals are commonly observed in nature and elucidating the mechanisms of fractal-related growth is a compelling issue for both fundamental science and technology. Here we report an in situ electron microscopy study of dynamic fractal growth of platinum during electrodeposition in a miniaturized electrochemical cell at varying growth conditions. Highly dendritic growth - either dense branching or ramified islands - are formed at the solid-electrolyte interface. We show how the diffusion length of ions in the electrolyte influences morphology selection and how instability induced by initial surface roughness, combined with local enhancement of electric field, gives rise to non-uniform branched deposition as a result of nucleation/growth at preferred locations. Comparing the growth behavior under these different conditions provides new insight into the fundamental mechanisms of platinum nucleation. PMID- 27714102 TI - Ultrafast fabrication of highly active BiVO4 photoanodes by hybrid microwave annealing for unbiased solar water splitting. AB - Hybrid microwave annealing (HMA) with a silicon susceptor in a household microwave oven produces BiVO4-based photoanodes of much improved performance in photoelectrochemical water oxidation in only 6 min relative to conventional thermal annealing in a traditional muffle furnace (FA) that needs a much longer time, 300 min. This technique can apply equally effectively to bare as well as modified BiVO4 by Mo-doping, heterojunction formation with WO3, and an oxygen evolution co-catalyst. Relative to FA, HMA forms BiVO4 films of smaller feature sizes, higher porosity, and increased three dimensional roughness, which decrease the diffusion distance of holes to the surface and thereby increase mainly the bulk charge separation efficiency (etabulk) of the photoanodes. Thus, the HMA treated BiVO4/WO3 film achieves the state-of-the art etabulk of ~90% for water oxidation. Combination of a photoanode of NiOOH/FeOOH/BiVO4/WO3 (HMA, 6 min) with a 2p c-Si solar cell allows a solar to hydrogen conversion efficiency of ~5.0% in unbiased overall water splitting, which is also comparable to the state-of-the art for a similar material combination. PMID- 27714103 TI - Competition between self-inclusion and drug binding explains the pH dependence of the cyclodextrin drug carrier - molecular modelling and electrochemistry studies. AB - A non-toxic lipoic acid derivative of beta cyclodextrin (betaCDLip) with an electron-rich aromatic linker was studied as a carrier for the drug doxorubicin with the aim of decreasing the toxic side effects of this drug. The modified cyclodextrin strengthened the drug binding and differentiated the complex-forming ability with dependence on pH. The stability constants of the complexes were evaluated by voltammetry and spectrofluorometry. Molecular modelling provided deeper insight into the nature of the ligand structure itself and the drug-ligand interactions, showing the different contributions of the self-inclusion of the ligand substituent at different pH values. As a result, the modes of interaction of betaCDLip with the drug and factors affecting the stabilities of the complex under the pH conditions of healthy and tumour cells could be discovered and explained. PMID- 27714104 TI - A 3D co-culture microtissue model of the human placenta for nanotoxicity assessment. AB - There is increasing evidence that certain nanoparticles (NPs) can overcome the placental barrier, raising concerns on potential adverse effects on the growing fetus. But even in the absence of placental transfer, NPs may pose a risk to proper fetal development if they interfere with the viability and functionality of the placental tissue. The effects of NPs on the human placenta are not well studied or understood, and predictive in vitro placenta models to achieve mechanistic insights on NP-placenta interactions are essentially lacking. Using the scaffold-free hanging drop technology, we developed a well-organized and highly reproducible 3D co-culture microtissue (MT) model consisting of a core of placental fibroblasts surrounded by a trophoblast cell layer, which resembles the structure of the in vivo placental tissue. We could show that secretion levels of human chorionic gonadotropin (hCG) were significantly higher in 3D than in 2D cell cultures, which indicates an enhanced differentiation of trophoblasts grown on 3D MTs. NP toxicity assessment revealed that cadmium telluride (CdTe) and copper oxide (CuO) NPs but not titanium dioxide (TiO2) NPs decreased MT viability and reduced the release of hCG. NP acute toxicity was significantly reduced in 3D co-culture MTs compared to 2D monocultures. Taken together, 3D placental MTs provide a new and promising model for the fast generation of tissue-relevant acute NP toxicity data, which are indispensable for the safe development of NPs for industrial, commercial and medical applications. PMID- 27714105 TI - Mechanism of potassium ion intercalation staging in few layered graphene from in situ Raman spectroscopy. AB - Recently emerging potassium ion (K-ion) batteries offer a lower-cost alternative to lithium-ion batteries while enabling comparably high storage capacity. Here, we leverage the strong Raman spectroscopic response of few-layered graphene to provide the first insight into the electrochemical staging sequence for K+ ions in graphitic carbons. Our analysis reveals the signature of a dilute stage I compound that precedes formation of ordered intercalation compounds transitioning from stage VI (KC72), stage II (KC24), and stage I (KC8) and correlates electrochemical responses to the stage formation. Overall, our study emphasizes a minimum barrier to transfer the general understanding acquired for lithium-ion battery anodes to cheaper, earth abundant K-ion battery systems ideally suited for grid-scale storage. PMID- 27714106 TI - The influence of interfacial tensile strain on the charge transport characteristics of MoS2-based vertical heterojunction devices. AB - We demonstrate the charge transport characteristics of MoS2-based vertical heterojunction devices through the formation of interfacial strain. Atomically thin MoS2 bilayers were directly synthesized on a p-type Si substrate by using chemical vapor deposition to introduce an interfacial tensile strain in the vertical heterojunction diode structure, which was confirmed by Raman, X-ray and ultraviolet photoelectron spectroscopy techniques. The electrical and optoelectronic properties of the heterojunction devices with the as-grown MoS2 (A MoS2) on p-Si were compared with those of transferred MoS2 (T-MoS2)/p-Si devices. To clearly understand the charge transport characteristics induced by the interfacial tensile strain, the Fowler-Nordheim (FN) analysis of the electrical properties of the diode devices was conducted with the corresponding energy band diagrams. All of the fabricated MoS2-based vertical diodes exhibited clearly rectifying behaviors, but the photoresponse properties of the A-MoS2-based and T MoS2-based heterojunctions exhibited distinct differences. Interestingly, we found that the tunneling barrier heights of the A-MoS2-based heterojunction devices were relatively higher than those of the T-MoS2-based devices and were almost the same before and after illumination due to the interfacial tensile strain, whereas those of the T-MoS2-based devices were lowered after illumination. Our study will help further understand the charge transport properties of 2D material-based heterojunction devices in the presence of interfacial strain, ultimately enabling the design of electronic and optoelectronic devices with novel functionalities. PMID- 27714107 TI - Combining surface plasmonic and light extraction enhancement on InGaN quantum well light-emitters. AB - Surface plasmon coupling with light-emitters and surface nano-patterning have widely been used separately to improve low efficiency InGaN light-emitting diodes. We demonstrate a method where dielectric nano-patterning and Ag nanoparticles (NPs) are combined to provide both light extraction and internal quantum efficiency enhancement for InGaN/GaN quantum-well light-emitters. By fabricating dielectric nano-rod pattern on the GaN surface, an optical coating that improves the light extraction is obtained, and furthermore has a low refractive index which blue-shifts the plasmonic resonance of Ag NPs towards the emission wavelength. We investigate emission components from both the GaN and sapphire surface of the semiconductor crystal and show that Ag NPs on dielectric nano-pattern compared to a planar surface, result in a stronger enhancement. PMID- 27714108 TI - Carbohydrate-based amphiphilic nano delivery systems for cancer therapy. AB - Nanoparticles (NPs) are novel drug delivery systems that have been attracting more and more attention in recent years, and have been used for the treatment of cancer, infection, inflammation and other diseases. Among the numerous classes of materials employed for constructing NPs, organic polymers are outstanding due to the flexibility of design and synthesis and the ease of modification and functionalization. In particular, NP based amphiphilic polymers make a great contribution to the delivery of poorly-water soluble drugs. For example, natural, biocompatible and biodegradable products like polysaccharides are widely used as building blocks for the preparation of such drug delivery vehicles. This review will detail carbohydrate based amphiphilic polymeric systems for cancer therapy. Specifically, it focuses on the nature of the polymer employed for the preparation of targeted nanocarriers, the synthetic methods, as well as strategies for the application and evaluation of biological activity. Applications of the amphiphilic polymer systems include drug delivery, gene delivery, photosensitizer delivery, diagnostic imaging and specific ligand assisted cellular uptake. As a result, a thorough understanding of the relationship between chemical structure and biological properties facilitate the optimal design and rational clinical application of the resulting carbohydrate based nano delivery systems for cancer therapy. PMID- 27714109 TI - Transparent multi-layer graphene/polyethylene terephthalate structures with excellent microwave absorption and electromagnetic interference shielding performance. AB - A high-performance electromagnetic interference (EMI) shielding structure based on pure graphene (without doping) consists of several graphene sheets separated by transparent polyethylene terephthalate (PET) films. We report the theoretical and experimental design, and characterization of the multi-layer graphene/PET structures. With a total graphene thickness of only 4 nm, the graphene/PET sample demonstrated an average shielding effectiveness of 19.14 dB at 18-26.5 GHz, with a maximum microwave absorbance of 95.82% at 25.7 GHz, while maintaining a normalized visible transmittance of 80.5%. For the multi-layer graphene/PET samples, the contribution of absorption to the total shielding exceeds 96%, indicating that absorption is the dominant shielding mechanism, instead of reflection. The microwave absorbance of the multi-layer graphene/PET structure increases rapidly from the mono- to the four-layer structures, and then more gradually as the number of layers continues to increase when the thickness of PET is 1 mm. In addition, the microwave absorbance can be improved two-fold by increasing the separation between graphene layers. We believe that this multi layer graphene/PET structure, which exhibits high-performance microwave absorption and shielding, has great potential for applications in transparent EMI shielding devices, especially if EMI absorption is required. PMID- 27714110 TI - Mechanism of photocatalytic activity improvement of AgNPs/TiO2 by oxygen plasma irradiation. AB - Plasmonic metal Ag nanoparticles (AgNPs) on TiO2 thin films (AgNPs/TiO2) are a kind of excellent photocatalyst of high efficiency under visible light, and thus draw great interest nowadays. Further improvement of their photocatalytic activity (PA) is difficult but is of high importance for their applications. In this paper, oxygen plasma was taken to partially oxidize AgNPs deposited on the surface of TiO2 to form a structure with the configuration of a p-type semiconductor/plasmonic metal/n-type semiconductor (Ag2O/AgNPs/TiO2). The localized surface plasmon resonance (LSPR) of the AgNPs was strongly damped after oxygen plasma irradiation (OPI) but the photocatalytic activity was improved. The mechanisms of the photocatalytic activity improvement under UV and visible light were explored based on charge kinetics. PMID- 27714111 TI - Transferrin conjugated nontoxic carbon dots for doxorubicin delivery to target pediatric brain tumor cells. AB - Among various cancers, pediatric brain tumors represent the most common cancer type in children and the second most common cause of cancer related deaths. Anticancer drugs and therapies, such as doxorubicin (Dox), have severe side effects on patients during chemotherapy, especially for children as their bodies are still under development. These side effects are believed to be due to the lack of a delivery system with high efficacy and targeting selectivity, resulting in serious damages of normal cells. To improve the efficacy and selectivity, the transferrin (Trans) receptor mediated endocytosis can be utilized for drug delivery system design, as transferrin receptors are expressed on the blood brain barrier (BBB) and often over expressed in brain tumor cells. Carbon dots (C-Dots) have recently emerged as benign nanoparticles in biomedical applications owing to their good water solubility, tunable surface functionalities and excellent biocompatibility. The unique characteristics of C-Dots make them promising candidates for drug delivery development. In this study, carbon dots-transferrin doxorubicin covalent conjugate (C-Dots-Trans-Dox) was synthesized, characterized by different spectroscopic techniques and investigated for the potential application as a drug delivery system for anticancer drug doxorubicin to treat pediatric brain tumors. Our in vitro results demonstrate greater uptake of the C Dots-Trans-Dox conjugate compared to Dox alone presumably owing to the high levels of transferrin receptors on these tumor cells. Experiment showed that C Dots-Trans-Dox at 10 nM was significantly more cytotoxic than Dox alone, reducing viability by 14-45%, across multiple pediatric brain tumor cell lines. PMID- 27714112 TI - Modulating the optical properties of the AIE fluophor confined within UiO-66's nanochannels for chemical sensing. AB - Transformation of aggregation induced emission (AIE) molecules into functional materials can greatly tune their fluorescence properties and expand their related potential applications. Here, we demonstrate a facile strategy to modulate the fluorescence properties of AIE molecules by confining them within the nanochannels of metal-organic frameworks (MOFs). AIE molecules (4,4'-(hydrazine 1,2-diylidene bis(methanylylidene)) bis(3-hydroxybenzoic acid), HDBB) with pH dependent emission were successfully integrated into UiO-66 resulting in a UiO 66?HDBB complex while maintaining the crystal structure by the host-guest process. The fluorescence properties of HDBB can be modulated by virtue of the unique nanospace confining effect. Furthermore, UiO-66?HDBB was used as a sensitive and selective fluorescent probe for Cu2+ detection in aqueous solution. This study provides a facile strategy for the construction of high performance AIE based luminescent materials with adjustable properties for potential applications. PMID- 27714113 TI - Thermal conductivity of disordered two-dimensional binary alloys. AB - Using non-equilibrium molecular dynamics simulations, we have studied the effect of disorder on the thermal conductivity of two-dimensional (2D) C1-xNx alloys. We find that the thermal conductivity not only depends on the substitution concentration of nitrogen, but also strongly depends on the disorder distribution. A general linear relationship is revealed between the thermal conductivity and the participation ratio of phonons in 2D alloys. Localization mode analysis further indicates that the thermal conductivity variation in the ordered alloys can be attributed to the number of inequivalent atoms. As for the disordered alloys, we find that the thermal conductivity variation can be described by a simple linear formula with the disorder degree and the substitution concentration. The present study suggests some general guidance for phonon manipulation and thermal engineering in low dimensional alloys. PMID- 27714114 TI - Highly controllable double Fano resonances in plasmonic metasurfaces. AB - Creating plasmonic nanostructures with controllable Fano resonances is of great interest for a number of important applications including metamaterials and biosensors. Realizing double Fano resonances is even more challenging but may become favorable to the applications such as surface enhanced Raman scattering (SERS) and second harmonic generation (SHG). Here we have developed plasmonic metasurfaces consisting of a nanoring array and a metallic film separated by a dielectric spacer for the generation of double Fano resonances. The double Fano resonances are realized by the strong plasmonic coupling between the localized surface plasmon resonance (LSPR) mode of the nanoring array and the cavity modes of the metal-insulator-metal (MIM) structure, and consequently exhibit large electric field enhancements at double frequencies. The resonance wavelength, the linewidth and the wavelength separation of double Fano resonances can be well tailored by changing the cavity length of the structure and the parameters of the top array pattern including the diameter, periodicity, and shape. In addition, we develop a far-field coupling model to efficiently determine the cavity length of metasurface structures with double Fano resonances at specific wavelengths with much ease and acceptable accuracy compared to the time-consuming and computing resource-needed numerical simulations. PMID- 27714115 TI - Size-tunable synthesis of monolayer MoS2 nanoparticles and their applications in non-volatile memory devices. AB - We report the CVD synthesis of a monolayer of MoS2 nanoparticles such that the nanoparticle size was controlled over the range 5-100 nm and the chemical potential of sulfur was modified, both by controlling the hydrogen flow rate during the CVD process. As the hydrogen flow rate was increased, the reaction process of sulfur changed from a "sulfiding" process to a "sulfo-reductive" process, resulting in the growth of smaller MoS2 nanoparticles on the substrates. The size control, crystalline quality, chemical configuration, and distribution uniformity of the CVD-grown monolayer MoS2 nanoparticles were confirmed. The growth of the MoS2 nanoparticles at different edge states was studied using density functional theory calculations to clarify the size-tunable mechanism. A non-volatile memory device fabricated using the CVD-grown size-controlled 5 nm monolayer MoS2 nanoparticles as a floating gate showed a good memory window of 5 8 V and an excellent retention period of a decade. PMID- 27714116 TI - Long-term stability improvement of light-emitting diode using highly transparent graphene oxide paste. AB - A highly transparent paste adhesive is successfully fabricated by introducing graphene oxide (GO) to silicone paste adhesive by using a solvent-exchange method. The GO incorporated in the paste adhesive has a significant role in improving thermal conductivity, transparency and adhesive strength. The GO embedded silicone paste is applied as a die-attach paste to light-emitting diodes (LEDs) in order to enhance the optical quality of the LEDs. The presence of GO in the die-attach layer of the LEDs gives rise to the enhancement of luminous intensity, effective heat dissipation, improvement of moisture barrier property as well as high adhesive strength. Consequently, the LEDs with the GO-embedded die-attach paste exhibit enhanced long-term stability. This novel approach provides a feasible and effective strategy for improving LED performance. PMID- 27714117 TI - A mesoporous organosilica nano-bowl with high DNA loading capacity - a potential gene delivery carrier. AB - Mesoporous organosilica nanoparticles with a novel bowl-like morphology were synthesized. These nano-bowls possess uniform particle sizes around 180 nm and open cavities around 140 nm, which lead to higher loading capability for plasmid DNA than traditional silica-based nanoparticles. In vitro DNA transfection using these nano-bowls is demonstrated. PMID- 27714118 TI - A strategy to improve the efficiency of hole transporting materials: introduction of a highly symmetrical core. AB - The electronic, optical and hole transport properties of three new hole transporting materials (HTMs) with a planar core have been investigated by using density functional theory and Marcus theory. A reliable semi-rational formula was adopted to calculate the highest occupied molecular orbital (HOMO) levels of new HTMs. The results showed that the HOMO levels of new HTMs were 0.07-0.30 eV lower than those of Spiro-OMeTAD, and their absorption peaks appeared outside or close to the visible region and overlapped slightly with the absorption band of perovskites. Moreover, the Stokes shifts of the designing molecules were calculated to lie in a range from 72 to 124 nm, meaning that they could undergo large geometrical changes on excitation. More importantly, the hole mobility of new HTMs (0.099-0.27 cm2 v-1 s-1) was approximately two orders of magnitude higher than that of Spiro-OMeTAD (0.0056 cm2 v-1 s-1) due to strong hole coupling from a face-to-face packing pattern. Our results indicated that planar core-based HTMs could become potential candidates to replace the widely established Spiro OMeTAD. PMID- 27714119 TI - Highly active, stable and self-antimicrobial enzyme catalysts prepared by biomimetic mineralization of copper hydroxysulfate. AB - A nature-inspired approach to encapsulate enzymes in spindle-like copper hydroxysulfate nanocrystals was developed by a biomimetic mineralization process. Several types of enzymes including glucose oxidase (GOx), horseradish peroxidase (HRP), Candida antarctica lipase B (CALB) and cytochrome c (Cyt c) were successfully encapsulated in copper hydroxysulfate nanocrystals quickly (within 1 hour) with maintained or even greatly enhanced catalytic efficiencies (kcat/KM of Cyt c showed a 143-fold increase) and high stabilities, demonstrating the feasibility of utilizing copper hydroxysulfate nanocrystals as a novel type of nanocarrier for enzyme immobilization. In addition, by this approach, for the first time, we showed that an immobilized enzyme can be endowed with self antibacterial activity by an inorganic component. This self-antibacterial performance together with the improved catalytic efficiencies and stabilities can greatly benefit the enzymatic catalysis in aqueous media and promote the future development of novel biosensors. PMID- 27714120 TI - Tuning of the photoluminescence and up-conversion photoluminescence properties of single-walled carbon nanotubes by chemical functionalization. AB - Single-walled carbon nanotubes (SWNTs) were subjected to alkylation using alkyl bromide and alkyl dibromide, and the photoluminescence (PL) properties of the resulting alkylated SWNTs were characterized. Two new PL peaks were observed along with the intrinsic PL peak at 976 nm when alkyl bromide was used (SWNT-Bu: ~1095 and 1230 nm, SWNT-Bn: 1104 and 1197 nm). In contrast, the use of alpha,alpha'-dibromo-o-xylene as an alkyl dibromide primarily resulted in only one new PL peak, which was observed at 1231 nm. The results revealed that the Stokes shift of the new peaks was strongly influenced by the addition patterns of the substituents. In addition, the time-resolved PL decay profiles of the alkylated SWNTs revealed that the PL peaks possessing a larger Stokes shift had longer exciton lifetimes. The up-conversion PL (UCPL) intensity of the alkylated SWNTs at excitation wavelengths of 1100 and 1250 nm was estimated to be ~2.38 and ~2.35 times higher than that of the as-dispersed SWNTs, respectively.

AB - In this work, we report the first direct experimental observations of carbon nanotubes (CNT) field emitting in an oxygen environment, using aberration corrected environmental transmission electron microscopy in combination with an electrical biasing specimen holder under low-dose, field-free imaging conditions. Our studies show that while the CNTs remain stable during high vacuum field emission, they experience abrupt decreases in length, also termed "burn-back", when field-emitting in an oxygen environment at around 30 Pa pressure. Furthermore, we perform correlative field-free and aberration-corrected, high resolution transmission electron microscopy imaging to understand how the structure of the CNTs - particularly the opening of the nanotube caps - is influenced by its gas environment during field emission. This work provides significant insight into the mechanism of carbon nanotube behavior under non ideal field emission conditions. PMID- 27714122 TI - Optofluidic sensing from inkjet-printed droplets: the enormous enhancement by evaporation-induced spontaneous flow on photonic crystal biosilica. AB - Novel transducers for detecting an ultra-small volume of an analyte solution play pivotal roles in many applications such as chemical analysis, environmental protection and biomedical diagnosis. Recent advances in optofluidics offer tremendous opportunities for analyzing miniature amounts of samples with high detection sensitivity. In this work, we demonstrate enormous enhancement factors (106-107) of the detection limit for optofluidic analysis from inkjet-printed droplets by evaporation-induced spontaneous flow on photonic crystal biosilica when compared with conventional surface-enhanced Raman scattering (SERS) sensing using the pipette dispensing technology. Our computational fluid dynamics simulation has shown a strong recirculation flow inside the 100 picoliter droplet during the evaporation process due to the thermal Marangoni effect. The combination of the evaporation-induced spontaneous flow in micron-sized droplets and the highly hydrophilic photonic crystal biosilica is capable of providing a strong convection flow to combat the reverse diffusion force, resulting in a higher concentration of the analyte molecules at the diatom surface. In the meanwhile, high density hot-spots provided by the strongly coupled plasmonic nanoparticles with photonic crystal biosilica under a 1.5 MUm laser spot are verified by finite-difference time domain simulation, which is crucial for SERS sensing. Using a drop-on-demand inkjet device to dispense multiple 100 picoliter analyte droplets with pinpoint accuracy, we achieved the single molecule detection of Rhodamine 6G and label-free sensing of 4.5 * 10-17 g trinitrotoluene from only 200 nanoliter solution. PMID- 27714123 TI - Controllable synthesis of ultra-small metal-organic framework nanocrystals composed of copper(ii) carboxylates. AB - Controlling the size of metal-organic frameworks (MOFs) down to the nanoscale is of great importance for the optimization of their properties. Chemically synthesized MOF nanoparticles commonly range from tens of nanometers to several microns. Herein, a general two-ligand modulation strategy in an interface reaction system is developed to synthesize a series of ultra-small MOF nanocrystals composed of copper(ii) ions and carboxylate linkers. The size of these MOF nanocrystals can be tuned within 10 nm by the alkyl chain length, the ligand to metal ion ratio and the reaction time. The ion exchange and self assembly of the MOF nanocrystals were also investigated. They are well dispersed in nonpolar solvents applicable for spin-coating, suggesting their application potentials in functional thin film devices. PMID- 27714124 TI - Distinct metal-exchange pathways of doped Ag25 nanoclusters. AB - Atomically precise metal nanoclusters (NCs) containing more than one type of metal atom (i.e., doped or alloyed), due to synergistic effects, open new avenues for engineering the catalytic and optical properties of NCs in a manner that homometal NCs cannot. Unfortunately, it is still a major challenge to controllably introduce multimetallic dopants in NCs, understanding the dopants' positions, mechanism, and synergistic effects. To overcome these challenges, we designed a metal-exchange approach involving NCs as molecular templates and metal ions as the source of the incoming dopant. In particular, two structurally similar monodoped silver-rich NCs, [MAg24(SR)18]2- (M = Pd/Pt and SR: thiolate), were synthesized as templates to study their mechanistic transformation in response to the introduction of gold atoms. The controllable incorporation of Au atoms into the MAg24 framework facilitated the elucidation of distinct doping pathways through high-resolution mass spectrometry, optical spectroscopy and elemental analysis. Interestingly, gold replaced the central Pd atom of [PdAg24(SR)18]2- clusters to produce predominantly bimetallic [AuAg24(SR)18]- clusters along with a minor product of an [Au2Ag23(SR)18]- cluster. In contrast, the central Pt atom remained intact in [PtAg24(SR)18]2- clusters, and gold replaced the non-central Ag atoms to form trimetallic [AuxPtAg24-x(SR)18]2- NCs, where x = 1-2, with a portion of the starting [PtAg24(SR)18]2- NCs remaining. This study reveals some of the unusual metal-exchange pathways of doped NCs and the important role played by the initial metal dopant in directing the position of a second dopant in the final product. PMID- 27714125 TI - Turning off the majority-rules effect in two-dimensional hierarchical chiral assembly by introducing a chiral mismatch. AB - Understanding the mechanism in chiral transmission from a single molecule to a supramolecular level is fundamentally important to decipher the nonlinear amplification effect in the two-dimensional (2D) chiral assembly process. In this contribution, we report on the dramatically different nonlinear amplification effect in the chiral co-adsorber induced homochiral assemblies constructed by a series of homologous achiral building blocks on the graphite surface under control of the majority-rules principle. Homologous hexagonal networks are formed for 5-(benzyloxy)-isophthalic acid (BIC) derivatives with different alkyl lengths. While globally homochiral monolayers of BIC-C6 or BIC-C16 can be obtained by using a mixture of chiral co-adsorber 2-octanol with a small enantiomeric excess, such majority-rules principle based nonlinear chiral amplification is inoperative for the assembly of BIC-C10. Molecular mechanistic analysis indicates that BIC-C10 assembly can accommodate a chiral mismatched motif to form long-range ordered but short-range disordered crystalline networks, leading to the co-adsorption of enantiomers without enantioselectivity. The present results shed important insights into the significance of chirality mismatch during chiral transmission and benefit the understanding of chiral communication in a surface monolayer. PMID- 27714126 TI - 2D/3D perovskite hybrids as moisture-tolerant and efficient light absorbers for solar cells. AB - The lifetime and power conversion efficiency are the key issues for the commercialization of perovskite solar cells (PSCs). In this paper, the development of 2D/3D perovskite hybrids (CA2PbI4/MAPbIxCl3-x) was firstly demonstrated to be a reliable method to combine their advantages, and provided a new concept for achieving both stable and efficient PSCs through the hybridization of perovskites. 2D/3D perovskite hybrids afforded significantly improved moisture stability of films and devices without encapsulation in a high humidity of 63 +/- 5%, as compared with the 3D perovskite (MAPbIxCl3-x). The 2D/3D perovskite-hybrid film did not undergo any degradation after 40 days, while the 3D perovskite decomposed completely under the same conditions after 8 days. The 2D/3D perovskite-hybrid device maintained 54% of the original efficiency after 220 hours, whereas the 3D perovskite device lost all the efficiency within only 50 hours. Moreover, the 2D/3D perovskite hybrid achieved comparable device performances (PCE: 13.86%) to the 3D perovskite (PCE: 13.12%) after the optimization of device fabrication conditions. PMID- 27714127 TI - Programmable RNA microstructures for coordinated delivery of siRNAs. AB - RNA is a natural multifunctional polymer, and is an essential component in both complex pathways and structures within the cellular environment. For this reason, artificial self-assembling RNA nanostructures are emerging as a powerful tool with broad applications in drug delivery and metabolic pathway regulation. To date, coordinated delivery of functional molecules via programmable RNA assemblies has been primarily done using nanosize RNA scaffolds. However, larger scaffolds could expand existing capabilities for spatial arrangement of ligands, and enable the controlled delivery of highly concentrated molecular loads. Here, we investigate whether micron-size RNA scaffolds can be assembled and further functionalized with different cargos (e.g. various siRNAs and fluorescent tags) for their synchronized delivery to diseased cells. Since known design approaches to build large RNA scaffolds are still underdeveloped, we apply a tiling method widely used in DNA nanotechnology. DNA tiles have been extensively used to build a variety of scalable and modular structures that are easily decorated with other ligands. Here, we adapt a double crossover (DX) DNA tile motif to design de novo DX RNA tiles that assemble and form lattices via programmed sticky end interactions. We optimize assembly protocols to guarantee high yield of RNA lattices. The resulting constructs are robust and modular with respect to the presence of distinct siRNAs and fluorophores. RNA tiles and lattices are successfully transfected in either human breast cancer or prostate cancer cells, where they efficiently knockdown the expression of target genes. Blood serum stability assays indicate that RNA lattices are more resilient to nuclease degradation when compared to individual tiles, thus making them better suited for therapeutic purposes. Overall, because of its design simplicity, we anticipate that this approach will be utilized for a wide range of applications in therapeutic RNA nanotechnology. PMID- 27714128 TI - Role of shape in substrate-induced plasmonic shift and mode uncovering on gold nanocrystals. AB - A number of plasmonic devices and applications, such as chemical and biological sensors, plasmon-enhanced solar cells, optical nanoantennas, metamaterials and metasurfaces, require the deposition of plasmonic metal nanocrystals on various substrates. Because the localized plasmon resonance modes, energies and strengths are strongly dependent on the dielectric function of the surrounding environment, the substrate is expected to largely affect the plasmonic properties of supported metal nanocrystals. Therefore, understanding the effects of the substrate on the plasmonic properties of metal nanocrystals and the roles of the involved factors will be crucial for designing various plasmonic devices that are made of metal nanocrystals deposited on different substrates. Herein we report on our study and results of the effects of substrates with distinct dielectric functions on the plasmonic properties of three types of Au nanocrystals. A combination of experiments and numerical simulations shows that the presence of a substrate causes plasmonic shifts as well as the appearance of new plasmon modes. The plasmonic shifts and the emergence of new plasmon modes are found to be dependent on the particle shape of Au nanocrystals and in turn on the fractional particle surface area that is in contact with the supporting substrate. For Au nanospheres and nanorods, plasmonic shifts, less than 100 nm, are observed on the scattering spectra by changing the supporting substrate from indium tin oxide to silicon. In comparison, a giant spectral shift of more than 300 nm is obtained for Au nanoplates. Moreover, silicon substrates induce the emergence of an out-of-plane quadrupolar mode of Au nanoplates, which interacts with an out-of-plane octupolar mode to give rise to a distinct Fano resonance. The Fano resonance is found to become stronger as the thickness of Au nanoplates is decreased. These results are of great importance for understanding the plasmonic properties of noble metal nanocrystals supported on various substrates, and for designing novel plasmonic nanostructures with desired optical properties and functions. PMID- 27714129 TI - Geometric structure, electronic structure and optical absorption properties of one-dimensional thiolate-protected gold clusters containing a quasi-face-centered cubic (quasi-fcc) Au-core: a density-functional theoretical study. AB - Based on the recently reported atomic structures of thiolate-protected Au28(SR)20, Au36(SR)24, Au44(SR)28, and Au52(SR)32 clusters, a family of homogeneous, linear, thiolate-protected gold superstructures containing novel quasi-face-centered-cubic (quasi-fcc) Au-cores is theoretically envisioned, denoted as the Au20+8N(SR)16+4N cluster. By means of density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations, a unified view of the geometric structure, electronic structure, magic stable size and size-dependent NIR absorption properties of Au20+8N(SR)16+4N clusters is provided. We find that the Au20+8N(SR)16+4N clusters demonstrate oscillating transformation energies dependent on N. The odd-N clusters show more favorable (negative) reaction energies than the even-N clusters. The magic stability of recently reported Au28(SR)20, Au36(SR)24, Au44(SR)28, Au52(SR)32 and Au76(SR)44 clusters can be addressed from the relative reaction energies and geometric distortion of Au cores. A novel 4N + 4 magic electron-number is suggested for the Au20+8N(SR)16+4N cluster. Using the polyhedral skeletal electron pair theory (PSEPT) and the extended Huckel molecular orbital (EHMO) calculations, we suggest that the magic 4N + 4 electron number is correlated with the quasi-fcc Au-cores, which can be viewed as double helical tetrahedron-Au4 chains. The size-dependent optical absorption properties of Au20+8N(SR)16+4N clusters are revealed based on TD-DFT calculations. We propose that these clusters are potential candidates for the experimental synthesis of atomically precise one-dimensional ligand protected gold superstructures with tunable NIR absorption properties. PMID- 27714130 TI - Covalently linked multimers of gold nanoclusters Au102(p-MBA)44 and Au~250(p MBA)n. AB - We present the synthesis, separation, and characterization of covalently-bound multimers of para-mercaptobenzoic acid (p-MBA) protected gold nanoclusters. The multimers were synthesized by performing a ligand-exchange reaction of a pre characterized Au102(p-MBA)44 nanocluster with biphenyl-4,4'-dithiol (BPDT). The reaction products were separated using gel electrophoresis yielding several distinct bands. The bands were analyzed by transmission electron microscopy (TEM) revealing monomer, dimer, and trimer fractions of the nanocluster. TEM analysis of dimers in combination with molecular dynamics simulations suggest that the nanoclusters are covalently bound via a disulfide bridge between BPDT molecules. The linking chemistry is not specific to Au102(p-MBA)44. The same approach yields multimers also for a larger monodisperse p-MBA-protected cluster of approximately 250 gold atoms, Au~250(p-MBA)n. While the Au102(p-MBA)44 is not plasmonic, the Au~250(p-MBA)n nanocluster supports localized surface plasmon resonance (LSPR) at 530 nm. Multimers of the Au~250(p-MBA)n exhibit additional transitions in their UV-vis spectrum at 630 nm and 810 nm, indicating the presence of hybridized LSPR modes. Well-defined structures and relatively small sizes make these systems excellent candidates for connecting ab initio theoretical studies and experimental quantum plasmonics. Moreover, our work opens new possibilities in the controlled synthesis of advanced monodisperse nanocluster superstructures. PMID- 27714131 TI - C60(OH)22: a potential histone deacetylase inhibitor with anti-angiogenic activity. AB - C60(OH)22 has been reported to suppress human cancer by inhibiting angiogenesis. However, its mechanism of action remains unclear. To explore the role and mechanism of C60(OH)22 in human pancreatic cancer, siRNA knockdown, immunofluorescence and a matrigel plug mouse model were employed. The results demonstrated that C60(OH)22 suppresses endothelial cell invasion and tube formation in vitro. C60(OH)22 suppresses angiogenesis in human umbilical vein endothelial cell (HUVEC) xenograft mice. The enzymatic activities of MMP2 and MMP9, as well as the expression levels of HDAC1, HDAC2, HIF-1alpha and VEGF, were inhibited by C60(OH)22. The expression of RECK was up-regulated by C60(OH)22 in HUVECs. The expression levels of HIF-1alpha and VEGF were down-regulated and the expression of RECK was up-regulated after the knockdown of HDAC1 and HDAC2 in HUVECs. Cell invasion, tube formation, and the enzymatic activities of MMP2 and MMP9 were suppressed after the knockdown of HDAC1 or HDAC2 in HUVECs. PMID- 27714132 TI - Enzyme-free colorimetric determination of EV71 virus using a 3D-MnO2-PEG nanoflower and 4-MBA-MA-AgNPs. AB - We present a simple colorimetric assay for EV71 virus detection based on the aggregation of 4-mercaptobenzoic acid (4-MBA) and melamine (MA) modified silver nanoparticles (4-MBA-MA-AgNPs) in the presence of Mn2+. The EV71-Ab1 was incubated on a 96-well plate and the EV71-Ab2 was labeled on the surface of three dimensional nanoflower-like MnO2-PEG (3D-MnO2-PEG). After layer-by-layer immunoreactions, the EV71 virus and the corresponding 3D-MnO2-PEG-Ab2 were captured on the plate. With the addition of Vitamin C (Vc), Mn2+ was released from the 3D-MnO2-PEG and then the aggregation of the 4-MBA-MA-AgNPs was induced, allowing a naked-eye detection limit of EV71 virus to be as low as 5 * 104 particles per mL, which is about three orders of magnitude lower than the conventional enzyme-linked immunosorbent assay (ELISA). This enzyme-free immunoassay based on a hybrid 3D-MnO2 features signal amplification strategies via a simple reduction reaction. PMID- 27714133 TI - Efficient vacuum-free-processed quantum dot light-emitting diodes with printable liquid metal cathodes. AB - Colloidal quantum dot light-emitting diodes (QLEDs) are recognized as promising candidates for next generation displays. QLEDs can be fabricated by low-cost solution processing except for the metal electrodes, which, in general, are deposited by costly vacuum evaporation. To be fully compatible with the low-cost solution process, we herein demonstrate vacuum-free and solvent-free fabrication of electrodes using a printable liquid metal. With eutectic gallium-indium (EGaIn) based liquid metal cathodes, vacuum-free-processed QLEDs are demonstrated with superior external quantum efficiencies of 11.51%, 12.85% and 5.03% for red, green and blue devices, respectively, which are about 2-, 1.5- and 1.1-fold higher than those of the devices with thermally evaporated Al cathodes. The improved performance is attributable to the reduction of electron injection by the native oxide of EGaIn, which serves as an electron-blocking layer for the devices and thus improves the balance of carrier injection. Also, the T50 half lifetime of the vacuum-free-processed QLEDs is about 2-fold longer than that of the devices with Al cathodes. Our results demonstrate that EGaIn-based solvent free liquid metals are promising printable electrodes for realizing efficient, low-cost and vacuum-free-processed QLEDs. The elimination of vacuum and high temperature processes significantly reduces the production cost and paves the way for industrial roll-to-roll manufacturing of large area displays. PMID- 27714134 TI - Superhalogens as building blocks of two-dimensional organic-inorganic hybrid perovskites for optoelectronics applications. AB - Organic-inorganic hybrid perovskites, well known for their potential as the next generation solar cells, have found another niche application in optoelectronics. This was demonstrated in a recent experiment (L. Dou, et al., Science, 2015, 349, 1518) on atomically thin (C4H9NH3)2PbBr4, where, due to quantum confinement, the bandgap and the exciton binding energy are enhanced over their corresponding values in the three-dimensional bulk phase. Using density functional theory we show that when halogen atoms (e.g. I) are sequentially replaced with superhalogen molecules (e.g. BH4) the bandgap and exciton binding energy increase monotonically with the superhalogen content with the exciton binding energy of (C4H9NH3)2Pb(BH4)4 approaching the value in monolayer black phosphorus. Lead-free admixtures (C4H9NH3)2MI4-x(BH4)x (M = Sn and Ge; x = 0-4) also show a similar trend. Thus, a combination of quantum confinement and compositional change can be used as an effective strategy to tailor the bandgap and the exciton binding energy of two-dimensional hybrid perovskites, making them promising candidates for optoelectronic applications. PMID- 27714135 TI - Folate-based single cell screening using surface enhanced Raman microimaging. AB - Recent progress in nanotechnology and its application to biomedical settings have generated great advantages in dealing with early cancer diagnosis. The identification of the specific properties of cancer cells, such as the expression of particular plasma membrane molecular receptors, has become crucial in revealing the presence and in assessing the stage of development of the disease. Here we report a single cell screening approach based on Surface Enhanced Raman Scattering (SERS) microimaging. We fabricated a SERS-labelled nanovector based on the biofunctionalization of gold nanoparticles with folic acid. After treating the cells with the nanovector, we were able to distinguish three different cell populations from different cell lines (cancer HeLa and PC-3, and normal HaCaT lines), suitably chosen for their different expressions of folate binding proteins. The nanovector, indeed, binds much more efficiently on cancer cell lines than on normal ones, resulting in a higher SERS signal measured on cancer cells. These results pave the way for applications in single cell diagnostics and, potentially, in theranostics. PMID- 27714136 TI - Parametrization of nanoparticles: development of full-particle nanodescriptors. AB - While metal oxide nanoparticles (NPs) are one of the most commonly used nanomaterials, the theoretical models used to analyze and predict their behavior have been mostly based on just the chemical composition or the extrapolation from small metal oxide clusters' calculations. In this study, a set of novel, theoretical full-particle descriptors for modeling, grouping or read-across of metal oxide NP properties and biological activity was developed based on the force-field calculation of the potential energies of whole NPs. The capability of these nanodescriptors to group the nanomaterials acoording to their biological activity was demonstrated by Principal Component Analysis (PCA). The grouping provided by the PCA approach was found to be in good accordance with the algal growth inhibition data of well characterized nanoparticles, synthesized and measured inside the consortia of the EU 7FP framework MODERN project. PMID- 27714137 TI - Confinement of a beta-barrel protein in nanoperforated free-standing nanomembranes for ion transport. AB - Bioinspired free-standing nanomembranes (FSNMs) for selective ion transport have been tailored by immobilizing the Omp2a beta-barrel membrane protein inside nanoperforations created in flexible poly(lactic acid) (PLA) nanomembranes. Perforated PLA FSNMs have been prepared by spin-coating a 99 : 1 PLA : poly(vinyl alcohol) mixture, and through a phase segregation process nanofeatures with dimensions similar to the entire nanomembrane thickness (~110 nm) were induced. These nanofeatures have subsequently been transformed into nanoperforations (diameter: ~51 nm) by selective solvent etching. The protein confined inside the nanopores of PLA FSNMs preserves the beta-barrel structure and organizes in ovoid aggregates. The transport properties of Na+, K+, and Ca2+ across non-perforated PLA, nanoperforated PLA, and Omp2a-filled nanoperforated PLA have been monitored by measuring the nanomembrane resistance with electrochemical impedance spectroscopy (EIS). The incorporation of nanoperforations enhances the transport of ions across PLA nanomembranes, whereas the functionality of immobilized Omp2a is essential to exhibit effects similar to those observed in biological nanomembranes. Indeed, Omp2a-filled nanoperforated PLA nanomembranes exhibit stronger affinity towards Na+ and Ca2+ ions than towards K+. In summary, this work provides a novel bioinspired strategy to develop mechanically stable and flexible FSNMs with channels for ion transport, which are precisely located inside artificial nanoperforations, thus holding great potential for applications in biofiltration and biosensing. PMID- 27714138 TI - A facile hybrid 'flow and batch' access to substituted 3,4-dihydro-2H benzo[b][1,4]oxazinones. AB - We describe a simple flow chemistry approach to libraries of ethyl 3-oxo-2 (substituted-phenylamino)-3,4-dihydro-2H-benzo[b][1,4]oxazine-6-carboxylates (12a l) and N-ethyl-3-oxo-2-(substituted-phenylamino)-3,4-dihydro-2H benzo[b][1,4]oxazine-6-carboxamides (13a-l) in 38-87% yields. This scaffold is poorly described in the chemical literature. Screening against a panel of 11 cancer and one normal cell line showed that the amide linked library 13a-l was devoid of toxicity. Whereas the ester linked analogues 12b, 12c, 12g, 12j and 12l were highly cytotoxic with growth inhibition (GI50) values from 0.34 to >50 MUM across all cell lines, with the 2-OH-Ph substituted 12l analogue presenting with sub-micromolar potency against the A2780 (ovarian; 0.34 +/- 0.04 MUM), BEC-2 (glioblastoma; 0.35 +/- 0.06 MUM), MIA (pancreas; 0.91 +/- 0.054 MUM) and SMA (murine glioblastoma; 0.77 +/- 0.029 MUM) carcinoma cell lines. Interestingly, the U87 glioblastoma cell line showed inherent resistance to growth inhibition by all analogues (GI50 32 to >50 MUM) while the A2780 cells were highly sensitive (GI50 3.8-0.34 MUM), suggesting that the analogues developed herein may be valuable lead compounds for the development of ovarian carcinoma specific cytotoxic agents. The differences in amide versus ester cytotoxicity was consitent with esterase cleaveage to release the cytotoxic warhead. PMID- 27714139 TI - Catalyst-free bottom-up growth of graphene nanofeatures along with molecular templates on dielectric substrates. AB - Synthesis of graphene nanostructures has been investigated to provide outstanding properties for various applications. Herein, we report molecular thin film assisted growth of graphene into nanofeatures such as nanoribbons and nanoporous sheets along with a predetermined molecular orientation on dielectric substrates without metal catalysts. A Langmuir-Blodgett (LB) method was used for the formation of the molecularly patterned SiO2 substrates with ferric stearate layers, which acted as a template for the directional growth of the polypyrrole graphene precursor. The nanofeatures of the graphene were determined by the number of ferric stearate layers (e.g., nanoribbons from multiple layers and nanoporous sheets from a single layer). The graphene nanoribbons (GNRs) containing pyrrolic N enriched edges exhibited a p-type semiconducting behavior, whereas the nanoporous graphene sheets containing inhomogeneous pores and graphitic N enriched basal planes exhibited the typical electronic transport of nitrogen-doped graphene. Our approaches provide two central methods for graphene synthesis such as bottom-up and direct processes for the future development of graphene nanoelectronics. PMID- 27714140 TI - Self-assembly of the full-length amyloid Abeta42 protein in dimers. AB - The self-assembly of amyloid (Abeta) proteins into nano-aggregates is a hallmark of Alzheimer's disease (AD) development, yet the mechanism of how disordered monomers assemble into aggregates remains elusive. Here, we applied long-time molecular dynamics simulations to fully characterize the assembly of Abeta42 monomers into dimers. Monomers undergo conformational changes during their interaction, but the resulting dimer structures do not resemble those found in fibril structures. To identify natural conformations of dimers among a set of simulated ones, validation approaches were developed and applied, and a subset of dimer conformations were characterized. These dimers do not contain long beta strands that are usually found in fibrils. The dimers are stabilized primarily by interactions within the central hydrophobic regions and the C-terminal regions, with a contribution from local hydrogen bonding. The dimers are dynamic, as evidenced by the existence of a set of conformations and by the quantitative analyses of the dimer dissociation process. PMID- 27714141 TI - Vertical nanocolumn-assisted pluripotent stem cell colony formation with minimal cell-penetration. AB - The biological applications of vertical nanostructures mostly rely on their intracellular accessibility through the cellular membrane by promoting cell-to nanostructure interactions. Herein, we report a seemingly counter-intuitive approach for the spontaneous formation of mouse induced pluripotent stem cell (iPSC)-derived three-dimensional spherical colonies with unlimited self-renewal and differentiation potential. The comprehensive analyses of iPSCs cultured on vertical silicon nanocolumn arrays (vSNAs) with various nanocolumn geometries show reduced cell-to-substrate adhesion and enhanced cell-to-cell interactions under optimized vSNA conditions, successfully accommodating the spontaneous production of iPSC-derived spherical colonies. Remarkably, these colonies which were only minimally penetrated by and thereby easily harvested from wafer-sized vSNAs display a substantial increase in pluripotency marker expression and successfully differentiate into three germ layers. Our vSNAs capable of large scale fabrication, efficient for spherical colony formation, and reusable for multiple iPSC culture could serve as a broad-impact culture platform for stem cell research.

AB - By a combination of scanning tunneling microscopy, X-ray spectroscopic techniques and density functional theory calculations, we prove the formation of extended patterns of parallel, graphene nanoribbons with alternate zig-zag and armchair edges and selected width by surface-assisted Ullmann coupling polymerization and dehydrogenation of 1,6-dibromopyrene (C16H8Br2). Besides the relevance of these nanostructures for their possible application in nanodevices, we demonstrate the peculiarity of halogenated pyrene derivatives for the formation of nanoribbons, in particular on Ag(110). These results open the possibility of tuning the shape and dimension of nanoribbons (and hence the correlated electronic properties) by choosing suitably tailored or on-purpose designed molecular precursors.

PMID- 27714144 TI - Superparamagnetic anisotropic nano-assemblies with longer blood circulation in vivo: a highly efficient drug delivery carrier for leukemia therapy. AB - Leukemia, unlike solid tumors, has no definite shape and spreads throughout the whole circulatory system, therefore the therapy of leukemia requires medication to stay longer in the circulatory system. Anisotropic nanoparticles, showing longer blood circulating life than that of isotropic nanoparticles reported in previous research, meet the demands of leukemia therapy. Based on this strategy, superparamagnetic anisotropic nano-assemblies (SANs) were fabricated and loaded with vincristine (VCR) to form VCR-SANs. When compared to the same dose of VCR loaded isotropic nano-assemblies (SINs), the decrease in the leukocytes count and the positive expression ratio of CD13 in the VCR-SANs group were 19.38% and 16.4%, respectively, which indicated the improved anti-leukemia activity of the VCR-SANs. From the results of the pharmacokinetics study, the VCR-SANs remarkably held the amount of drug removed from the whole body per unit time half of the isotropic group and the concentration of drug in blood plasma against time was 2.1 times the isotropic group, demonstrating the rapid and sustained release behavior and longer blood circulation when combined with the results of in vivo tissue distribution studies. In summary, anisotropic nano-assemblies were found to be more promising than isotropic nano-assemblies via our in vivo and in vitro examinations.

AB - We report on photo-current generation in freestanding monolayered gold nanoparticle membranes excited by using a focused laser beam. The absence of a substrate leads to a 50% increase of the photo-current at the surface plasmon resonance. This current is attributed to a combination of trap state dynamics and bolometric effects in a nanocomposite medium yielding a temperature rise of 40 K.

AB - 2-Dimensional (2D) and 0-dimensional (0D) hybrid nanostructures have been reported as promising new systems for highly-sensitive and wavelength-tunable photodetectors. Although the performance of hybrid photodetectors was enhanced by charge injection from 0D nanocrystals (NCs) to 2D nanosheets (NSs), the response time of hybrid photodetectors is still very slow due to the trapping and leakage of residual carriers at the interfaces of the hybrid materials. Here, we demonstrate a MoS2/CdSe hybrid phototransistor with enhanced responsivity of 2.5 * 105 A W-1 and detectivity of 1.24 * 1014 Jones. In addition, the device exhibited a fast rise (taurise) and decay time (taudecay) of 60 ms, respectively. The mechanism for the improved photoresponse time has been discussed using a charge injection model in an n-n type heterojunction energy band diagram of hybrid materials.

AB - Carbon nanotubes (CNTs) have promising applications in a wide range of biomedical fields, including imaging, drug/gene delivery and other therapeutics; however, the biosafety concerns of CNTs should be addressed. To date, many reports have documented the toxicological effects on the cells, tissue or organs that are in direct contact with the tubes; however, there is limited evidence to unravel the secondary toxicity upon CNT treatment. Moreover, more effort is needed to gain a definitive understanding of the adverse outcome pathway (AOP) for CNTs, and a pragmatic framework for risk assessment has not been established yet. In the current study, we aimed to decipher the secondary toxicity to joints under CNT exposure. We demonstrated that carboxylated multi-wall CNTs (MWCNTs-COOH) significantly provoked systemic pro-inflammatory responses, leading to synovial inflammation within knee joints, as evidenced by the infiltration of pro inflammatory cells in the synovium and meniscus. Mechanistic studies showed that MWCNTs-COOH stimulated pro-inflammatory effects by activating macrophages, and the secreted pro-inflammatory cytokines primed the synoviocytes and chondrocytes, resulting in enhanced production of a large array of enzymes involved in articular cartilage degeneration, including matrix metalloproteinase (MMP) members and cyclooxygenase (COX) members, and increased enzymatic activity of MMPs was demonstrated. Blockade of the cytokines by antibodies significantly attenuated the production of these enzymes. Our current study thus suggests that there is a novel secondary toxicity of CNTs, namely a new AOP to understand the indirect effects of carbon nanotubes: synovial inflammation due to the alteration of the priming state of synoviocytes and chondrocytes under CNT-induced systemic inflammatory conditions. PMID- 27714148 TI - Selective killing of cells triggered by their mRNA signature in the presence of smart nanoparticles. AB - The design of nanoparticles that can selectively perform multiple roles is of utmost importance for the development of the next generation of nanoparticulate drug delivery systems. So far most research studies are focused on the customization of nanoparticulate carriers to maximize their drug loading, enhance their optical signature for tracking in cells or provide photo-responsive effects for therapeutic purposes. However, a vital requirement of the new generation of drug carriers must be the ability to deliver their payload selectively only to cells of interest rather than the majority of various cells in the vicinity. Here we show for the first time a new design of nanoparticulate drug carriers that can specifically distinguish different cell types based on their mRNA signature. These nanoparticles sense and efficiently kill model tumour cells by the delivery of an anti-cancer drug but retain their payload in cells lacking the specific mRNA target. PMID- 27714149 TI - Filter-free, junctionless structures for color sensing. AB - A simple structure, efficient color splitting, sufficient output of electrical signals, and low power consumption are the important characteristics of contemporary devices for color sensing. In this study, we developed filter-free, junctionless structures that exhibited a superior photo-thermo-electrical response under a low bias voltage and a short response time in milliseconds. Although our compact sensor had a simple single-layer trench-like aluminum (Al) structure, it could perform multiple functions, including light harvesting, color selective absorption, photo-thermo-electrical transformation, and the ability to collect photoinduced differences in electrical signals. This device exploited near-field surface plasmon resonance and cavity effects to enhance the intensity of the electric field and the color-selective absorption, ultimately resulting in significant current signals in its structured Al film. This strategy significantly simplifies not only the components of the color sensor but also its fabrication; for example, red, green, and blue color detection devices could be prepared simultaneously through a single lithography, etching, and deposition step. With its ability to provide functional filter-free, junctionless structures, this strategy has great potential for the production of devices that operate on different kinds of substrates, thereby bridging various applications of color sensing technologies. PMID- 27714150 TI - Synthesis of hybrid metal-organic frameworks of {FexMyM'1-x-y}-MIL-88B and the use of anions to control their structural features. AB - The controlled formation of metal-organic frameworks (MOFs) or coordination polymers (CPs) with suitable components and structural features is one of the most important themes in MOF research. In particular, the reliable preparation of hybrid MOFs containing more than two different kinds of metal ions or organic linkers and a comprehensive understanding of the structural flexibility of MOFs are the central issues for the production of MOFs with the desired properties. We report the synthesis of micro-sized hybrid MOF particles [also known as coordination polymer particles (CPPs)] containing two or three kinds of metal ions in each particle: {FexMyM'1-x-y}-MIL-88B (MIL stands for Materials of Institut Lavoisier, M and M' = Ga, Co, or Mn). Scanning electron microscopy images revealed the formation of well-defined uniform micro-sized hexagonal rods, and energy-dispersive X-ray spectroscopy and elemental mapping images verified the simultaneous incorporation of two or three kinds of metal ions within the CPPs. Interestingly, the structural features of CPPs made from MIL-88B were controlled by altering the anions involved in the structure. Incorporating large acetylacetonate anions within the structure resulted in the closed MIL-88B structure with a small cell volume. However, the open MIL-88B structure with a large cell volume was obtained when small chloride anions were incorporated. The intermediate semi-open MIL-88B structure was also prepared using nitrate anions. Three different structural forms of MIL-88B were verified by powder X-ray diffraction, whole pattern fitting, and thermogravimetric analysis. PMID- 27714151 TI - High-energy lithium-ion hybrid supercapacitors composed of hierarchical urchin like WO3/C anodes and MOF-derived polyhedral hollow carbon cathodes. AB - A lithium-ion hybrid supercapacitor (Li-HSC) comprising a Li-ion battery type anode and an electrochemical double layer capacitance (EDLC) type cathode has attracted much interest because it accomplishes a large energy density without compromising the power density. In this work, hierarchical carbon coated WO3 (WO3/C) with a unique mesoporous structure and metal-organic framework derived nitrogen-doped carbon hollow polyhedra (MOF-NC) are prepared and adopted as the anode and the cathode for Li-HSCs. The hierarchical mesoporous WO3/C microspheres assembled by radially oriented WO3/C nanorods along the (001) plane enable effective Li+ insertion, thus exhibit high capacity, excellent rate performance and a long cycling life due to their high Li+ conductivity, electronic conductivity and structural robustness. The WO3/C structure shows a reversible specific capacity of 508 mA h g-1 at a 0.1 C rate (1 C = 696 mA h g-1) after 160 discharging-charging cycles with excellent rate capability. The MOF-NC achieved the specific capacity of 269.9 F g-1 at a current density of 0.2 A g-1. At a high current density of 6 A g-1, 92.4% of the initial capacity could be retained after 2000 discharging-charging cycles, suggesting excellent cycle stability. The Li HSC comprising a WO3/C anode and a MOF-NC cathode boasts a large energy density of 159.97 W h kg-1 at a power density of 173.6 W kg-1 and 88.3% of the capacity is retained at a current density of 5 A g-1 after 3000 charging-discharging cycles, which are better than those previously reported for Li-HSCs. The high energy and power densities of the Li-HSCs of WO3/C//MOF-NC render large potential in energy storage. PMID- 27714152 TI - Slow and fast absorption saturation of black phosphorus: experiment and modelling. AB - According to the excited-state decay time, a slow saturable absorber model was employed to obtain the ground-state absorption and excited-state absorption cross sections sigmags and sigmaes of black phosphorus (BP) nanosheets, which are (1.25 +/- 0.07) * 10-16 cm2 and (2.97 +/- 0.21) * 10-17 cm2 at 515 nm, and (5.95 +/- 0.17) * 10-18 cm2 and (5.19 +/- 0.71) * 10-19 cm2 at 1030 nm, respectively. In comparison, the sigmags and sigmaes of MoS2 and graphene were also obtained with the same model. The ratio sigmaes/sigmags of BP is the smallest (only 0.24 +/- 0.03 at 515 nm and 0.09 +/- 0.01 at 1030 nm) among the three two-dimensional layered materials both at 515 nm and 1030 nm. Relatively large ground-state transition probability and weak loss of excited-state absorption result in good saturable absorption performance. In comparison with MoS2 and graphene, the much lower saturation intensity of BP can be well explained from this perspective.

AB - Enzyme triggered probes with a self-immolative linker for rapid and sensitive hydrolase detection through a cascade reaction have been reported. Their utility was proved by the preparation of three model compounds and their evaluation as enzyme substrates and demonstration of their applicability as fluorogenic probes for screening lipase, esterase and protease activities. These probes represent a new class of fluorogenic compounds, are stable under aqueous conditions and not susceptible to nonspecific degradation. The utilization of the carbamate cleavable linkage in a probe structure allows moving away of the bulky fluorophore from the enzyme recognition unit and targets different classes of enzymes with the same substrate. PMID- 27714154 TI - Characterization of nanoporous structures: from three dimensions to two dimensions. AB - The scanning electron microscope (SEM) has revealed a colorful three-dimensional world due to its great depth of field. However, the abundance of structural information imposes tough challenges to quantitative image analysis. In the current investigation, we developed a SEM-image polishing (SIP) based quantitative SEM-image analysis (QSIA) technique. As an example, QSIA was employed to characterize nanoporous silica. The results confirmed that the nanoporous silica samples, processed via sol-gel methods, were single-parameter, with the pore size being the only variable. The QSIA technique may pave the way to fast and accurate data mining of nanoscaled materials. PMID- 27714155 TI - Chemical synthesis and enzymatic properties of RNase A analogues designed to enhance second-step catalytic activity. AB - In this paper, we have used total chemical synthesis of RNase A analogues in order to probe the molecular basis of enzyme catalysis. Our goal was to obligately fill the adenine-binding pocket on the enzyme molecule, and to thus pre-orient the imidazole side chain of His119 in its catalytically productive orientation. Two designed analogues of the RNase A protein molecule that contained an adenine moiety covalently bound to distinct amino acid side chains adjacent to the adenine binding pocket were prepared. A crystal structure of one analogue was determined at 2.3 A resolution. Kinetic data for RNA transphosporylation and 2',3' cyclic mononucleotide hydrolysis were acquired for the adenine-containing RNase A analogue proteins. As anticipated, the presence of a covalently attached adenine on the enzyme molecule decreased the rate of transphosphorylation and increased the rate of hydrolysis, although the magnitude of the effects was small. This work illustrates the use of total protein synthesis to investigate the chemistry of enzyme catalysis in ways not possible through traditional biochemistry or molecular biology. PMID- 27714156 TI - A simple melting-diffusing-reacting strategy to fabricate S/NiS2-C for lithium sulfur batteries. AB - S/NiS2-C composites were fabricated using a sample melting-diffusing-reacting strategy. When the elemental sulfur content in the composite is 54.9 wt%, it shows good cyclic performance and delivers a specific capacity of 730 mA h g-1 after 200 cycles at 0.5 C and 544 mA h g-1 after 500 cycles at 2 C. The elemental sulfur content can be adjusted, and when the elemental sulfur content is increased to 64.8 wt% and 76.0 wt%, the cathodes can maintain a stable cyclic capacity of 386 and 312 mA h g-1 after being discharged/charged at 2 C for 500 cycles respectively. The carbon structure and the uniformly distributed nickel disulfide in the S/NiS2-C composites efficiently stabilizes the polysulfides and also facilitates the conversion of electrochemical reactions. PMID- 27714157 TI - A direct assay of butyrylcholinesterase activity using a fluorescent substrate. AB - In this study, we report a direct fluorometric assay for butyrylcholinesterase (BChE) activity and screening of its inhibitor, using a fluorescent substrate. 2 (2-(5,6-Dimethoxy-1,3-dioxoisoindolin-2-yl)acetoxy)-N,N,N-trimethylethan-1 ammonium iodide (1) was hydrolyzed by BChE, and its fluorescence was quenched by an intramolecular photoinduced electron transfer process. The resulting change in fluorescence provided a facile method for real-time BChE activity testing. Remarkably, 1 was selectively hydrolyzed by BChE, even in the presence of excess acetylcholinesterase, thereby facilitating the specific monitoring of BChE activity. This assay method is also useful for screening potential BChE inhibitors. Given its simplicity, selectivity, and higher assay speed, this method may be extended to high-throughput screening of BChE inhibitors and relevant drug discovery. PMID- 27714158 TI - The role of the crystalline face in the ordering of 6-mercaptopurine self assembled monolayers on gold. AB - Well-ordered molecular films play an important role in nanotechnology, from device fabrication to surface patterning. Self-assembled monolayers (SAMs) of 6 mercaptopurine (6MP) on the Au(100)-(1 * 1) and Au(111)-(1 * 1) have been used to understand the interplay of molecule-substrate interactions for heterocyclic thiols capable of binding to the surface by two anchors, which spontaneously form a highly disordered film on Au(111). Our results reveal that for the same surface coverage the simple change of the substrate from Au(111)-(1 * 1) to Au(100)-(1 * 1) eliminates molecular disorder and yields well-ordered SAMs. We discuss these findings in terms of differences in the surface mobility of 6MP species on these surfaces, the energetics of the adsorption sites, and the number of degrees of freedom of these substrates for a molecule with reduced surface mobility resulting from its two surface anchors. These results reveal the presence of subtle molecule-substrate interactions involving the heteroatom that drastically alter SAM properties and therefore strongly impact on our ability to control physical properties and to build devices at the nanoscale. PMID- 27714159 TI - Switch on the high thermal conductivity of graphene paper. AB - This work reports on the discovery of a high thermal conductivity (kappa) switch on phenomenon in high purity graphene paper (GP) when its temperature is reduced from room temperature down to 10 K. The kappa after switch-on (1732 to 3013 W m-1 K-1) is 4-8 times that before switch-on. The triggering temperature is 245-260 K. The switch-on behavior is attributed to the thermal expansion mismatch between pure graphene flakes and impurity-embedded flakes. This is confirmed by the switch behavior of the temperature coefficient of resistance. Before switch-on, the interactions between pure graphene flakes and surrounding impurity-embedded flakes efficiently suppress phonon transport in GP. After switch-on, the structure separation frees the pure graphene flakes from the impurity-embedded neighbors, leading to a several-fold kappa increase. The measured kappa before and after switch-on is consistent with the literature reported kappa values of supported and suspended graphene. By conducting comparison studies with pyrolytic graphite, graphene oxide paper and partly reduced graphene paper, the whole physical picture is illustrated clearly. The thermal expansion induced switch-on is feasible only for high purity GP materials. This finding points out a novel way to switch on/off the thermal conductivity of graphene paper based on substrate-phonon scattering. PMID- 27714160 TI - A novel and highly efficient earth-abundant Cu3P with TiO2 "P-N" heterojunction nanophotocatalyst for hydrogen evolution from water. AB - Semiconductor-based photocatalytic hydrogen (H2) evolution from water is of great importance for solar-to-chemical conversion processes to boost and promote the future hydrogen economy. Here, for the first time, we demonstrate that p-Cu3P coupled with n-TiO2 forms a novel hybrid structure which accelerates electron hole pair separation and transfer for improved photocatalytic H2-evolution activity. The rate of H2 evolution of the optimized Cu3P/TiO2 (7940 MUmol h-1 g 1) is 11 times higher than that of bare TiO2, with an apparent quantum efficiency (AQE) of 4.6%. This work may provide more insight into the synthesis of novel phosphide-based hybrid materials with high photocatalytic H2-evolution activity and sufficient stability for solar-to-chemical conversion and utilization. PMID- 27714161 TI - Inflammation-sensitive in situ smart scaffolding for regenerative medicine. AB - To cope with the rapid evolution of the tissue engineering field, it is now essential to incorporate the use of on-site responsive scaffolds. Therefore, it is of utmost importance to find new 'Intelligent' biomaterials that can respond to the physicochemical changes in the microenvironment. In this present report, we have developed biocompatible stimuli responsive polyaniline-multiwalled carbon nanotube/poly(N-isopropylacrylamide), (PANI-MWCNT/PNIPAm) composite nanofiber networks and demonstrated the physiological temperature coordinated cell grafting phenomenon on its surface. The composite nanofibers were prepared by a two-step process initiated with an assisted in situ polymerization followed by electrospinning. To obtain a smooth surface in individual nanofibers with the thinnest diameter, the component ratios and electrospinning conditions were optimized. The temperature-gated rearrangements of the molecular structure are characterized by FTIR spectroscopy with simultaneous macromolecular architecture changes reflected on the surface morphology, average diameter and pore size as determined by scanning electron microscopy. The stimuli responsiveness of the nanofibers has first been optimized with computational modeling of temperature sensitive components (coil-like and globular conformations) to tune the mechanism for temperature dependent interaction during in situ scaffolding with the cell membrane. The nanofiber networks show excellent biocompatibility, tested with fibroblasts and also show excellent sensitivity to inflammation to combat loco regional acidosis that delay the wound healing process by an in vitro model that has been developed for testing the proposed responsiveness of the composite nanofiber networks. Cellular adhesion and detachment are regulated through physiological temperature and show normal proliferation of the grafted cells on the composite nanofibers. Thus, we report for the first time, the development of physiological temperature gated inflammation-sensitive smart biomaterials for advanced tissue regeneration and regenerative medicine.

AB - Correction for 'In situ growth of fluorescent silicon nanocrystals in a monolithic microcapsule as a photostable, versatile platform' by Guixian Zhu, et al., Nanoscale, 2016, 8, 15645-15657. PMID- 27714163 TI - A modular clamp-like mechanism to regulate the activity of nucleic-acid target responsive nanoswitches with external activators. AB - Here we demonstrate a general and modular approach to regulate the activity of target-responsive DNA-based nanoswitches. We do so by coupling together two DNA based responsive elements: a triplex-forming clamp-like probe able to bind a specific DNA sequence and a split aptamer selected to bind a small molecule. In the presence of the specific target of one of the above responsive elements, the nanoswitch partially folds and its ability to bind the second target is restored. With this approach we can finely modulate the affinity of both DNA-recognition elements and aptamers using an external ligand. The modular nature of our strategy makes it easily generalizable to different DNA based recognition elements. As a demonstration of this we successfully designed five different DNA nanoswitches whose responsiveness can be regulated by different molecular effectors and targets. The convenience with which this mechanism is designed suggests that it may prove a useful tool by which sensors, genetic networks and other biotechnology devices employing nucleic-acid based receptors can be controlled with an external input. PMID- 27714164 TI - Effect of temperature on the viscoelastic properties of nano-confined liquid mixtures. AB - The behaviour of fluids confined in nanoscale gaps plays a central role in molecular science and nanofluidics, with applications ranging from biological function to multiscale printing, osmosis and filtration, lab-on-chip technology and friction reduction. Here atomic force microscopy is used to shear five different mixtures of hexadecane and squalane confined between the tip apex and atomically flat graphite. The shearing amplitudes are typically <2 nm, hence reflecting highly localised information at the interface. The evolution of each mixture's viscoelastic properties is studied as a function of temperature, between 20 degrees C and 100 degrees C. The results, complemented by sub nanometre resolution images of the interface, show that spatial organisation of the liquid molecules at the surface of graphite largely dominates the measurements. Squalane presents a higher effective affinity for the surface by forming a robust self-assembled layer in all mixtures. This results in a step like change of the viscous and elastic response of the confined liquid as the confining pressure increases. In contrast, measurements in pure hexadecane show a continuous and linear increase in the apparent viscosity with pressure at all temperatures. This is interpreted as a more fragile interfacial layer and images show that it can be completely removed at high temperatures. Depending on the mixture composition, measurements can be strongly location-dependent which suggests molecular clustering and nanoscale phase separation at the interface. PMID- 27714165 TI - Plasmonic ELISA based on the controlled growth of silver nanoparticles. AB - Herein, we demonstrate a plasmonic ELISA based on the alkaline phosphatase (ALP) mediated growth of silver nanoparticles (AgNPs) for the sensitive, rapid, and naked-eye detection of cancer biomarkers in clinical serum samples. This approach was used to measure the low-abundance alpha fetal protein (AFP) in clinical sera, which demonstrates its great capability in the differentiation of cancers and evaluation of therapeutic responses. Impressively, the readout of the plasmonic assay depends on the rapid formation of Ag colloidal solutions with various degrees of yellow color, which can be distinguished by the naked eye, without the need for sophisticated platforms. The limit of detection of the plasmonic ELISA for alpha fetal protein (AFP) can be as low as 0.23 ng mL-1, which is approximately 10 folds lower than that of conventional ELISA. This plasmonic ELISA opens a new avenue for the early detection of cancers and monitoring of cancer reoccurrence especially in resource-poor regions where convenient diagnostic tools are highly desirable.

AB - Group III-VI compounds MIIIXVI (M = Ga, In; X = S, Se, Te) are one class of important 2D layered materials and are currently attracting increasing interest due to their unique electronic and optoelectronic properties and their great potential applications in various other fields. Similar to 2D layered transition metal dichalcogenides (TMDs), MIIIXVI also have the significant merits of ultrathin thickness, ultrahigh surface-to-volume ratio, and high compatibility with flexible devices. More impressively, in contrast with TMDCs, MIIIXVI demonstrate many superior properties, such as direct band gap electronic structure, high carrier mobility, rare p-type electronic behaviors, high charge density, and so on. These unique characteristics cause high-performance device applications in electronics, optoelectronics, and optics. In this review, we aim to provide a summary of the state-of-the-art of research activities in 2D layered MIIIXVI materials. The scope of the review covers the synthesis and properties of 2D layered MIIIXVI materials and their van der Waals heterostructures. We especially focus on the applications in electronics and optoelectronics. Moreover, the review concludes with some perspectives on future developments in this field. PMID- 27714167 TI - 3D-branched hierarchical 3C-SiC/ZnO heterostructures for high-performance photodetectors. AB - The ultra-sensitive photodetection of different wavelengths holds promising applications in high-performance optoelectronic devices and it requires an efficient and suitable semiconductor unit. Herein, we demonstrated the designable synthesis of 3D-branched hierarchical 3C-SiC/ZnO heterostructures by a three-step process and their assembling into an ultrasensitive photodetector. Microstructure analyses using high-resolution transmission electron microscopy reveal that the hierarchical 3C-SiC/ZnO heterostructure is composed of single-crystal 3C-SiC nanowires as a central stem and numerous well-aligned single-crystalline ZnO nanorods as branch shells. Optoelectronic tests on the 3C-SiC/ZnO heterostructure photodetector verify the outstanding photo-detection performance with an ultrahigh EQE (1.69 * 108%), a superior photoresponsivity (4.8 * 105 A W-1), a very fast response time (a rise time of 40 ms and a decay time of 60 ms), a high photo-dark current ratio of 187.8 and an excellent photocurrent stability and reproducibility, which is significantly advantageous or comparable to those of ZnO and other inorganic semiconductor nanostructure based photodetectors. To understand the excellent photodetection of hierarchical 3C-SiC/ZnO heterostructures, a band-gap energy diagram describing the photogenerated electron transport process is plotted and the corresponding mechanism is discussed. The strategy proposed in the present work will open up more opportunities for the design and boost of ultra-sensitive photodetectors based on semiconductor heterostructures. PMID- 27714168 TI - Targeted SERS nanosensors measure physicochemical gradients and free energy changes in live 3D tumor spheroids. AB - Use of multicellular tumor spheroids (MTS) to investigate therapies has gained impetus because they have potential to mimic factors including zonation, hypoxia and drug-resistance. However, analysis remains difficult and often destroys 3D integrity. Here we report an optical technique using targeted nanosensors that allows in situ 3D mapping of redox potential gradients whilst retaining MTS morphology and function. The magnitude of the redox potential gradient can be quantified as a free energy difference (DeltaG) and used as a measurement of MTS viability. We found that by delivering different doses of radiotherapy to MTS we could correlate loss of DeltaG with increasing therapeutic dose. In addition, we found that resistance to drug therapy was indicated by an increase in DeltaG. This robust and reproducible technique allows interrogation of an in vitro tumor model's bioenergetic response to therapy, indicating its potential as a tool for therapy development.

AB - There is a crucial demand for cost-effective hydrogen evolution reaction (HER) catalysts towards future renewable energy systems, and the development of such catalysts operating under all pH conditions still remains a challenging task. In this work, a one-step facile approach to synthesizing nitrogen-doped carbon encapsulating molybdenum phosphide nanoparticles (MoP NPs@NC) is introduced by using ammonium molybdate, ammonium dihydrogen phosphate and melamine as precursor. Benefitting from structural advantages, including ultrasmall nanoparticles, large exposed surface area and fast charge transfer, MoP NPs@NC exhibits excellent HER catalytic activities with small overpotentials at all pH values (j = 10 mA cm-2 at eta = 115, 136 and 80 mV in 0.5 M H2SO4, 1.0 M phosphate buffer solution and 1.0 M KOH, respectively.). Meanwhile, the high catalytic activities of MoP NPs@NC under both neutral and basic conditions have never been achieved before for molybdenum phosphide-based catalysts. Additionally, the encapsulation by N-doped carbon effectively prevents the MoP NPs from corrosion, exhibiting nearly unfading stability after 100 h testing in 0.5 M H2SO4. Thus, our work could pave a new avenue for unprecedented design and fabrication of novel low-cost metal phosphide electrocatalysts encapsulated by N doped carbon.

AB - The synthesis of a series of novel N-substituted tetrahydro-beta-carboline imidazolium salt derivatives is presented. The biological properties of the compounds were evaluated in vitro against a panel of human tumor cell lines. The results suggest that the benzimidazole ring and 1-(naphthalen-2-yl)ethan-1-one or 2-naphthylmethyl substituent at the imidazolyl-3-position were vital for modulating cytotoxic activity. Compound 41 was observed as a potent derivative with IC50 values of 3.24-8.78 MUM and exhibited cytotoxic activity selectively against HL-60, A-549 and MCF-7 cell lines. Meanwhile, high inhibitory activities selectively against HL-60 and MCF-7 cell lines were observed for compound 51. Moreover, compound 51 was able to induce G1 phase cell cycle arrest and apoptosis in MCF-7 cells. The cytotoxicity of compound 51 against human normal lung epithelial cell line BEAS-2B was further evaluated.

AB - A host-guest interaction between Ru(ii)-complexes and sugar-capped beta cyclodextrin was employed to synthesize metalloglycodendrimers. These glycodendrimers demonstrated selective carbohydrate-protein interactions and controlled the delivery of the Ru(ii) complexes into cancer cells, which may facilitate cell-specific apoptosis. Lectin binding assay revealed micromolar range IC50 values with different plant lectins. Cell viability assay and confocal imaging studies of Ru(ii) complexes exhibited cytotoxic activities in cancer cells compared to normal cells with IC50 values close to other literature Ru(ii) complexes. The cell death inducer was found to accumulate favorably to the endoplasmic reticulum (ER) and induced ER stress in cells. The upregulation of CHOP, caspase-3 and caspase-12 disturbed the ER morphology initiating the apoptosis pathway. PMID- 27714173 TI - Near-infrared emissive carbon dots for two-photon fluorescence bioimaging. AB - Fluorescent probes with both excitation and emission in the near-infrared (NIR) region are highly attractive in the field of bioimaging. Herein, NIR emissive carbon dots (CDs, lambdamax = 683 nm) capable of excitation with a NIR femtosecond pulse laser (850 nm) are reported for the first time. The NIR CDs also hold a variety of superior features including excellent water dispersibility, narrow emission bands, and high quantum yields (QY = 16.8%). Further studies reveal that the emission of the NIR CDs derives predominantly from the surface molecular state mechanism. More interestingly, the NIR CDs are verified to have very low cytotoxicity and show capabilities for two-photon fluorescence bioimaging. Finally, the NIR CDs are shown to be easily modified with fluorescein isothiocyanate (FITC) and moved into living cells. These findings demonstrate that the as-prepared NIR CDs could not only be potentially employed for deep-tissue two-photon bioimaging, but also used as an effective carrier for delivery of drugs that can't (or hardly) enter into living cells directly.

AB - Nuclear magnetic resonance (NMR) spectroscopy has been established as a potent method for the determination of foldamer structures in solution. However, the NMR techniques could be limited by averaging, so additional experimental techniques are often needed to fully endorse the folding properties of a sequence. We have recently demonstrated that oligo-gamma-peptides composed of 4-amino(methyl)-1,3 thiazole-5-carboxylic acids (ATCs) adopt an original helical fold stabilized by hydrogen bonds forming C9 pseudocycles. The main objective of the present work is to reinvestigate the folding of ATC oligomer 1 in order to identify reliable FT IR and NMR structural markers that are of value for tracking the degree of organization of ATC-based peptides. PMID- 27714175 TI - Inherent N,O-containing carbon frameworks as electrode materials for high performance supercapacitors. AB - N,O-Containing micropore-dominated materials have been developed successfully via temperature-dependent cross-linking of 4,4'-(dioxo-diphenyl-2,3,6,7 tetraazaanthracenediyl)dibenzonitrile (DPDN) monomers. By employing a molecular engineering strategy, we have designed and synthesized a series of porous heteroatom-containing carbon frameworks (PHCFs), in which nitrogen and oxygen heteroatoms are distributed homogeneously throughout the whole framework at the atomic level, which can ensure the stability of its electrical properties. The as made PHCFs@550 exhibits a high specific capacitance of 378 F g-1, with an excellent long cycling life, including excellent cycling stability (capacitance retention of ca. 120% over 20 000 cycles). Moreover, the successful preparation of PHCFs provides new insights for the fabrication of nitrogen and oxygen containing electrode materials from readily available components via a facile route. PMID- 27714176 TI - Nanoscale orbital excitations and the infrared spectrum of a molecular Mott insulator: A15-Cs3C60. AB - The quantum physics of ions and electrons behind low-energy spectra of strongly correlated molecular conductors, superconductors and Mott insulators is poorly known, yet fascinating especially in orbitally degenerate cases. The fulleride insulator Cs3C60 (A15), one such system, exhibits infrared (IR) spectra with low temperature peak features and splittings suggestive of static Jahn-Teller distortions with a breakdown of orbital symmetry in the molecular site. That is puzzling, since there is no detectable static distortion, and because the features and splittings disappear upon modest heating, which they should not. Taking advantage of the Mott-induced collapse of electronic wavefunctions from lattice-extended to nanoscale localized inside a caged molecular site, we show that the unbroken spin and orbital symmetry of the ion multiplets explains the IR spectrum without adjustable parameters. This demonstrates the importance of a fully quantum treatment of nuclear positions and orbital momenta in the Mott insulator sites, dynamically but not statically distorted. The observed demise of these features with temperature is explained by the thermal population of a multiplet term whose nuclear positions are essentially undistorted, but whose energy is very low-lying. That term is in fact a scaled-down orbital excitation analogous to that of other Mott insulators, with the same spin 1/2 as the ground state, but with a larger orbital momentum of two instead of one.

AB - Recent research efforts about iron oxide nanoparticles has focused on the development of iron oxide-based T1 contrast agents for magnetic resonance imaging (MRI), such as ultrasmall iron oxide nanospheres (USNPs <4 nm) and ultrathin nanowires (NW, diameter <4 nm). In this paper, we report the cellular uptake behaviors of these two types of ultrasmall scale nanostructures on HepG2 cells. Both these two nanostructures were functionalized with tannic acid and their physical and chemical properties were carefully analyzed before cellular tests. Both USNPs and NWs exhibited strong paramagnetic signals, a property suitable for T1 MRI contrast agents. The distinct shapes also caused much difference in their cellular uptake behaviors. Specifically, the uptake of USNPs was five times higher than that of NWs after 72 hours incubation. The shape-dependent cellular uptake can potentially lead to different blood circulation times, and subsequently different applications of these two types of ultrasmall nanostructures. PMID- 27714178 TI - 5-Bromo-2'-deoxycytidine-a potential DNA photosensitizer. AB - A double-stranded oligonucleotide, 80 base pairs in length, was multiply labeled with 5-bromo-2'-deoxycytidine (BrdC) using polymerase chain reaction (PCR). The modified oligonucleotide was irradiated with 300 nm photons and its damage was assayed by employing DHPLC, LC-MS and denaturing polyacrylamide gel electrophoresis (PAGE). Two types of damage were demonstrated, namely, single strand breaks (SSBs) and intrastrand cross-links (ICLs); the ICLs were in the form of d(G^C) and d(C^C) dimers. The former species are probably formed due to photoinduced electron transfer between the photoexcited BrdC and the ground state 2'-deoxyguanosine (dG), whereas the latter is a result of a cycloaddition reaction. Since SSBs and ICLs are potentially lethal to the cell, BrdC could be considered as a nucleoside with possible clinical applications. PMID- 27714179 TI - A one-pot synthesis of tetrazolones from acid chlorides: understanding functional group compatibility, and application to the late-stage functionalization of marketed drugs. AB - A one-pot and scalable synthesis of tetrazolones (tetrazol-5-ones) from acid chlorides using azidotrimethylsilane is presented. The reaction tolerates many functional groups and can furnish aryl-, heteroaryl-, alkenyl-, or alkyl substituted tetrazolone products in moderate to excellent yield (14-94%). No reduction in yield was observed when the reaction was undertaken on a larger scale (20-36 g). The method could be used for the late-stage functionalization of pharmaceuticals, to provide tetrazolone congeners of the marketed drugs aspirin, indomethacin, probenecid, telmisartan, bexarotene, niacin (vitamin B3), and the active metabolite of the recently-launched immuno-modulatory agent, BG-12 (Tecfidera(r)). The ability of a tetrazolone group to serve as a bioisostere of a carboxylic acid, and to improve drug pharmacokinetic profiles is also highlighted. PMID- 27714180 TI - Radical-mediated divergent cyclization of benzamides toward perfluorinated or cyanated isoquinolinediones. AB - A simple and efficient copper-controlled divergent cyclization of benzamides, which leads to perfluorinated or cyanated isoquinolinediones, is developed. In the presence of AIBN, methacryloyl benzamides with perfluoroalkyl iodides undergo cascade radical addition/cyclization to afford perfluoroinated isoquinolinediones as the major product under metal-free conditions, whereas the use of CuI (10 mol%) is able to redirect the cyclization to yield isoquinolinediones bearing an alpha-cyano quaternary carbon center. The cyclization features controllable divergent synthesis and a broad substrate scope as well as highly practical reaction conditions, thereby making this strategy a highly attractive means to fluorinate or cyanate isoquinolinediones.

Compared with pure Sb2O3 materials, the Sb2O3/graphene composite exhibits superior electrochemical performance as an anode material in lithium-ion batteries, and this should be attributed to the synergistic effects of the high conductivity of graphene and the novel nest-shaped structure of the composite. PMID- 27714183 TI - TiO2 nanotubes with laterally spaced ordering enable optimized hierarchical structures with significantly enhanced photocatalytic H2 generation. AB - In the present work we grow self-organized TiO2 nanotube arrays with a defined and controlled regular spacing between individual nanotubes. These defined intertube gaps allow one to build up hierarchical 1D-branched structures, conformally coated on the nanotube walls using a layer by layer nanoparticle TiO2 decoration of the individual tubes, i.e. having not only a high control over the TiO2 nanotube host structure but also on the harvesting layers. After optimizing the intertube spacing, we build host-guest arrays that show a drastically enhanced performance in photocatalytic H2 generation, compared to any arrangement of conventional TiO2 nanotubes or conventional TiO2 nanoparticle layers. We show this beneficial effect to be due to a combination of an increased large surface area (mainly provided by the nanoparticle layers) with a fast transport of the harvested charge within the passivated 1D nanotubes. We anticipate that this type of hierarchical structures based on TiO2 nanotubes with adjustable spacing will find even wider application, as they provide an unprecedented controllable combination of surface area and carrier transport. PMID- 27714184 TI - Functional nanocomposites with perfect nanoblending between water-soluble polymers and hydrophobic inorganic nanoparticles: applications to electric stimuli-responsive films. AB - There is rising demand for metal or metal oxide nanoparticle (NP)/polymer nanocomposite films with desired functionalities. However, it is difficult to directly combine well-defined NPs synthesized using organic fatty acids in nonpolar media with water-soluble polymers, except polyelectrolytes with specific functional moieties, because they differ in their hydrophobic/hydrophilic properties. We have developed a facile and universal hydrophilic/hydrophobic layer-by-layer (LbL) assembly method that enables perfect nanoblending between water-soluble polymers and hydrophobic NPs, maintaining their specific functionalities. Various hydrophobic NPs stabilized by using oleic acid (OA) (e.g., OA-TiO2, OA-Fe3O4, OA-Ag, and OA-Pt NPs) were directly LbL assembled with various water-soluble polymers (including biomaterials) containing carboxylic acid (-COOH), tertiary ammonium (N+), hydroxyl (-OH), and/or ether (-O-) groups. This adsorption behavior is based on the affinities between water-soluble polymers with multidentate binding sites and the surfaces of metal or metal oxide NPs stabilized by OA ligands. Our approach can be used to fabricate unipolar switching nonvolatile memory devices with ON/OFF current ratios greater than ~1010 and good memory stability, despite the use of water-soluble polymers. PMID- 27714185 TI - Self-propelled autonomous nanomotors meet microfluidics. AB - Self-propelled autonomous nano/micromotors are in the forefront of current materials science and technology research. These small machines convert chemical energy from the environment into propulsion, and they can move autonomously in the environment and are capable of chemotaxis or magnetotaxis. They can be used for drug delivery, microsurgeries or environmental remediation. It is of immense interest from a future biomedical application point of view to understand the motion of the nano/micromotors in microfluidic channels. In this minireview, we review the progress on the use of nano/micromotors in microfluidic channels and lab-on-chip devices.

AB - A highly efficient tetra-n-butylammonium iodide (TBAI) triggered procedure for 3 sulfenylation of indoles with Bunte salts is demonstrated. This protocol provides a simple strategy to prepare 3-alkylthioindoles and 3-arylthioindoles from the corresponding indoles under metal-free and oxidant-free conditions.

AB - A short, convergent and general strategy for stereoselective total synthesis of biologically active alpha-substituted gamma-hydroxymethyl gamma-lactone based natural products cananginone C and debilisone A has been developed. The salient features of this synthesis include Cadiot-Chodkiewicz coupling, Evans allylation, Sharpless asymmetric dihydroxylation and gamma-lactonization. The originally proposed structure of debilisone A has been revised. PMID- 27714188 TI - Direct nanopatterning of polymer/silver nanoblocks under low energy electron beam irradiation. AB - In this communication, we report on the growth, direct writing and nanopatterning of polymer/silver nanoblocks under low energy electron beam irradiation using a scanning electron microscope. The nanoblocks are produced by placing a droplet of an ethylene glycol solution containing silver nitrate and polyvinylpyrrolidone diluted in ethanol directly on a hot substrate heated up to 150 degrees C. Upon complete evaporation of the droplet, nanospheres, nano- and micro-triangles and nanoblocks made of silver-containing polymers, form over the substrate surface. Considering the nanoblocks as a model system, we demonstrate that such nanostructures are extremely sensitive to the e-beam extracted from the source of a scanning electron microscope operating at low acceleration voltages (between 5 and 7 kV). This sensitivity allows us to efficiently create various nanopatterns (e.g. arrays of holes, oblique slits and nanotrenches) in the material under e beam irradiation. In addition to the possibility of writing, the nanoblocks revealed a self-healing ability allowing them to recover a relatively smooth surface after etching. Thanks to these properties, such nanomaterials can be used as a support for data writing and erasing on the nanoscale under low energy electron beam irradiation. PMID- 27714189 TI - Reactions of 1,2-diaza-1,3-butadienes with propargyl alcohol as an approach to novel bi-heterocyclic systems. AB - Here we describe the reaction of 1,2-diaza-1,3-dienes and propargyl alcohol furnishing alpha-(prop-2-yn-1-yloxy)hydrazones that are converted into novel alkyl-1-oxa-7,8-diazaspiro[4.4]nona-3,8-dien-6-ones, by means of 2,3-Wittig rearrangement under very mild conditions. The same alpha-(prop-2-yn-1 yloxy)hydrazones, treated with benzyl azides furnish the corresponding alpha [(1,2,3-triazol-4-yl)methoxy]hydrazones, via Cu(ii)-catalyzed 1,3-dipolar cycloaddition. Their subsequent base-promoted cyclization produces interesting pyrazolone-triazole derivatives. The impact of this work can be ascribable to the attractiveness of the bi-heterocyclic systems obtained and to the ease of the synthetic methodologies proposed. PMID- 27714190 TI - Solid-phase synthesis and fluorine-18 radiolabeling of cycloRGDyK. AB - Solid-phase peptide synthesis, head-to-tail cyclization, and subsequent radiolabeling provided a reproducible, simple, rapid synthetic method to generate the cyclic peptide radiotracer cRGDyK([18F]FBA). Herein is reported the first on resin cyclization and 18F-radiolabeling of a cyclic peptide (cRGDyK) in an overall peptide synthesis yield of 88% (cRGDyK(NH2)) and subsequent radiolabeling yield of 14 +/- 2% (decay corrected, n = 4). This approach is generally applicable to the development of an automated process for the synthesis of cyclic radiolabeled peptides for positron emission tomography (PET).

AB - The first enantioselective synthesis of the fungal metabolite (+)-O methylasparvenone was achieved in eight steps and 22% overall yield from inexpensive 3,4,5-trimethoxybenzaldehyde dimethyl acetal. Key steps include (i) early-stage asymmetric alkynylation of an aromatic aldehyde with a propiolate, (ii) intramolecular Friedel-Crafts acylation, and (iii) site-selective cleavage of an aryl methyl ether. PMID- 27714192 TI - Preparation of a Fe3O4-Au-GO nanocomposite for simultaneous treatment of oil/water separation and dye decomposition. AB - A nanocomposite capable of simultaneously controlling multiple water pollutants (soluble organic dye and insoluble chemical solvent) has been obtained. The Au and Fe3O4 nanoparticles (NPs) were modified on a graphene oxide (GO) surface via light reduction and covalent attachment. The obtained Fe3O4-Au-GO nanocomposite has magnetic driving ability and catalytic applications. The nanocomposite can form emulsions after wrapping an insoluble and volatile organic solvent inside; moreover, the multi-layer graphene shell structure may delay volatilization of the solvent, ensuring that the oil droplets are collected efficiently and completely by the Fe3O4-Au-GO nanocomposite. At the same time, the Au NPs on the surface of the composite can effectively catalyze the decomposition of an organic dye in water and the recovery of the nanocomposite catalyst can also be realized using an external magnetic field. The simultaneous treatment of non-soluble oil (organic solvents) and organic dyes in water can be realized by the Fe3O4-Au-GO nanocomposite. Therefore, based on surface modification of GO, one material with two types of water pollution treatment functions was realized. This provides a new way for the simultaneous treatment of oil separation and dye decomposition, and the assembled structure may result in emulsions to give new applications in fuel cells and other fields.

This reaction has excellent functional group tolerance, and exhibits a broad range of potassium trifluoroborate components, allowing for the facile C-H functionalization of electronically varied N-carbamoyl THCs in high efficiency with excellent regioselectivity. PMID- 27714194 TI - Organic synthesis reactions on-water at the organic-liquid water interface. AB - Organic reactions that occur at the water interface for water-insoluble compounds, and reactions in water solution for water soluble compounds, has added a powerful dimension to prospects for organic synthesis under more beneficial economic and environmental conditions. Many organic molecules are partially soluble in water and reactions that appear as heterogeneous mixtures and suspensions may involve on-water and in-water reaction modes occurring simultaneously. The behavior of water molecules and organic molecules at this interface is discussed in the light of reported theoretical and experimental studies. The on-water catalytic effect, relative to neat reactions or organic solvents, ranges from factors of several hundred times to 1-2 times and it depends on the properties of reactant compounds. In some cases when on-water reactions produce quantitative yields of water-insoluble products they can reach ideal synthetic aspirations. PMID- 27714195 TI - A systematic exploration of the effects of flexibility and basicity on sigma (sigma) receptor binding in a series of substituted diamines. AB - The sigma-1 receptor (S1R) has attracted a great deal of attention as a prospective drug target due to its involvement in numerous neurological disorders and, more recently, for its therapeutic potential in neuropathic pain. As there was no crystal structure of this membrane-bound protein reported until 2016, ligand generation was driven by pharmacophore refinements to the general model suggested by Glennon and co-workers. The generalised S1R pharmacophore comprises a central region where a basic amino group is preferred, flanked by two hydrophobic groups. Guided by this pharmacophore, S1R ligands containing piperazines, piperazinones, and ethylenediamines have been developed. In the current work, we systematically deconstructed the piperazine core of a prototypic piperazine S1R ligand (vide infra) developed in our laboratories. Although we did not improve the affinity at the S1R compared to the lead, we identified several features important for affinity and selectivity. These included at least one basic nitrogen atom, conformational flexibility and, for S1R, a secondary or tertiary amine group proximal to the anisole. Furthermore, S2R selectivity can be tailored with functional group modifications of the N-atom proximal to the anisole. PMID- 27714196 TI - Monitoring interfacial lectin binding with nanomolar sensitivity using a plasmon field effect transistor. AB - By immobilizing glycopolymers onto the surface of the recently developed plasmonic field effect transistor (FET), the recognition between lectins and surface-immobilized glycopolymers can be detected over a wide dynamic range (10 10 to 10-4 M) in an environment that resembles the glycocalyx. The binding to the sensor surface by various lectins was tested, and the selectivities and relative binding affinity trends observed in solution were maintained on the sensor surface, and the significantly higher avidities are attributed to cluster glycoside effects that occur on the surface. The combination of polymer surface chemistry and optoelectronic output in this device architecture produces amongst the highest reported detection sensitivity for ConA. This work demonstrates the benefits that arise from combining emerging device architectures and soft-matter systems to create cutting edge nanotechnologies that lend themselves to fundamental biological studies and integration into point-of-use diagnostics and sensors. PMID- 27714197 TI - A diversity-oriented approach to indolocarbazoles via Fischer indolization and olefin metathesis: total synthesis of tjipanazole D and I. AB - New synthetic strategies to indolocarbazoles have been reported via two-fold Fischer indolization under green conditions using l-(+)-tartaric acid and N,N dimethyl urea. Starting with cyclohexanone, a bench-top starting material, this methodology has been extended to the total synthesis of natural products such as tjipanazoles D and I as well as the core structure of asteropusazole and racemosin B. Here, atom economical reactions like ring-closing metathesis, enyne metathesis, and the Diels-Alder reaction have been used as key steps. Diverse strategies demonstrated here are useful in medicinal chemistry and materials science to design a library of decorated indoles.

AB - Chemoenzymatic transglycosylation catalyzed by endo-S mutants is a powerful tool for in vitro glycoengineering of therapeutic antibodies. In this paper, we report a one-pot chemoenzymatic synthesis of glycoengineered Herceptin using an egg-yolk sialylglycopeptide (SGP) substrate. Combining this one-pot strategy with novel non-natural SGP derivatives carrying azido or alkyne tags, glycosite-specific conjugation was enabled for the development of new antibody-drug conjugates (ADCs). The site-specific ADCs and semi-site-specific dual-drug ADCs were successfully achieved and characterized with SDS-PAGE, intact antibody or ADC mass spectrometry analysis, and PNGase-F digestion analysis. Cancer cell cytotoxicity assay revealed that small-molecule drug release of these ADCs relied on the cleavable Val-Cit linker fragment embedded in the structure. These results represent a new approach for glycosite-specific and dual-drug ADC design and rapid synthesis, and also provide the structural requirement for their biologic activities.

These eight membered ring containing heterocycles exhibited moderately high anticancer activity against four cancer cell lines; human cervix cancer cell line (HeLa), human prostate cancer cell line (DU145), human breast cancer cell line (MCF-7) and human breast adenocarcinoma epithelial cell line (MDA-MB-231). Our results indicate that these compounds have a weak cytotoxic effect on normal human mammary epithelial cell line (MCF-10A). Cell cycle and apoptosis assay indicate that they inhibit the cell cycle at the G2/M phase and induce apoptosis. Through the RED100 assay, it is evident that they have potential to inhibit pBR 322 plasmid DNA cleavage by BamH1. UV-visible, fluorescence titration and viscosity studies suggested that these compounds possess DNA binding affinity. PMID- 27714203 TI - Hydro-actuation of hybrid carbon nanotube yarn muscles. AB - Hybrid hydro-responsive actuators are developed by infiltrating carbon nanotube yarns using poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate). These actuators demonstrate impressive rotation and contraction in response to water due to volumetric expansion of the helical arrangement of carbon nanotubes. The total torsional stroke is 3720 revolutions per m and the simultaneously generated contractive strain reaches 24% at a paddle-to-yarn mass ratio of 350. The contraction output can furthermore be significantly enhanced by constraining the rotational motion and it reaches 68% with an applied stress of 1 MPa. Additionally, hybrid yarns exhibit an approximately linear response to humidity changes and show extra capability of electrical actuation, which, combined with the excellent hydro-actuation performance, endow them with great potential for a variety of applications including artificial muscles, hydro-driven generators, moisture switches and microfluidic mixers.

AB - Organic-inorganic hybrid perovskites, direct band-gap semiconductors, have shown tremendous promise for optoelectronic device fabrication. We report the first colloidal synthetic approach to prepare ultrasmall (~1.5 nm diameter), white light emitting, organic-inorganic hybrid perovskite nanoclusters. The nearly pure white-light emitting ultrasmall nanoclusters were obtained by selectively manipulating the surface chemistry (passivating ligands and surface trap-states) and controlled substitution of halide ions. The nanoclusters displayed a combination of band-edge and broadband photoluminescence properties, covering a major part of the visible region of the solar spectrum with unprecedentedly large quantum yields of ~12% and photoluminescence lifetime of ~20 ns. The intrinsic white-light emission of perovskite nanoclusters makes them ideal and low cost hybrid nanomaterials for solid-state lighting applications.

AB - Supramolecular chemistry and self-assembly provide a valuable chance to understand the complicated topological structures on a molecular level. Two types of classical mechanically interlocked molecules, rotaxanes and catenanes, possess non-covalent mechanical bonds and have attracted more attention not only in supramolecular chemistry but also in the fields of materials science, nanotechnology and bioscience. In the past decades, the template-directed clipping reaction based on imine chemistry has become one of the most efficient methods for the construction of functionalized rotaxanes and catenanes. In this review, we outlined the main progress of rotaxanes and catenanes using the template-directed clipping approach of imine chemistry.

Theoretical (DFT) and experimental (NMR) studies on the free and Na+-complexed cyclic trimers (3-5) and tetramers (6-8) demonstrate that annulation of the rigidified peptoids can generate new hosts with the ability to sequestrate one or two sodium cations with the affinities and stoichiometries defined by the macrocycle morphology. Ion transport studies have been also performed in order to better appreciate the factors promoting transmembrane cation translocation. PMID- 27714210 TI - WO3-x sensitized TiO2 spheres with full-spectrum-driven photocatalytic activities from UV to near infrared. AB - To make full use of solar energy for photocatalytic reactions, in this work, we developed full-spectrum-responsive photocatalysts with noteworthy photocatalytic activities under either UV, visible or even near infrared irradiation for the photodegradation of methylene blue. The core-shell structure of TiO2@WO3-x is designed from the consideration of combining the full-spectrum photo-absorption properties of WO3-x with the excellent semiconductor properties of TiO2. As expected, the WO3-x sensitized TiO2 sphere gives rise to a prominently strong optical absorption in the whole region of 300-2500 nm and thus displays desired photocatalytic properties for the full utilization of all solar energy, especially in the unexploited NIR part, which accounts for most of the sunlight. Encouraged by the above exciting photocatalytic outcome, we then go further to propose a plausible mechanism for interpreting the NIR-driven photocatalytic properties, which is based on the hypothesis of low-valent W5+ site induced free electrons and evidence-based ESR results.

AB - A Cu(i)-catalyzed retro-aldol reaction of beta-hydroxyketones with ortho aminobenzaldehydes and nicotinaldehydes is reported that produces a range of quinolines and naphthyridines with high efficiency and selectivity. This reaction uses beta-hydroxyketones as a regiospecific ketone-protected enolate source via copper-catalyzed retro-aldol Calpha-Cbeta bond cleavage. The in situ generated copper enolate undergoes kinetically favorable cyclization with ortho-amino aryl aldehydes to produce quinolines and naphthyridines in a chemo- and regioselective manner. The mild and weakly basic reaction conditions also suppress possible side reactions of benzaldehydes under strongly basic conditions, resulting in improved reaction yields.

AB - Although the biosynthetic pathway of Neocarazostatin A (1) has been identified, the detailed enzymatic reactions underlying the assembly of the carbazole ring still remain largely unknown. We demonstrate here that NzsH, a putative thiamine diphosphate dependent enzyme, can catalyze an acyloin coupling reaction between indole-3-pyruvate and pyruvate to generate a beta-ketoacid intermediate. Our findings thus shed light on further characterization of the unusual biosynthetic pathway of the bacterial tricyclic carbazole alkaloids. PMID- 27714213 TI - The evolution of a stereoselective synthesis of the C1-C16 fragment of bryostatins. AB - The development of a synthesis of the C1-C16 fragment of bryostatins in which the key step is a stereoselective oxy-Michael reaction used to assemble the cis-2,6 disubstituted tetrahydropyran with the exocyclic alkene already installed, is described. Following early work using Stille reactions to prepare precursors for oxy-Michael reactions, a more efficient route was devised based on a ketophosphonate-aldehyde condensation to prepare the key dienone. Synthesis of the aldehyde required for the ketophosphonate condensation involved the highly stereoselective addition of a diorganocuprate derived from allylmagnesium bromide and copper(i) iodide to the methyl 5-hydroxyhex-2-ynoate prepared by ring-opening of a protected glycidol using lithiated methyl propiolate. Ester reduction, selective alcohol protection and oxidative cleavage of the terminal double bond gave the required aldehyde. The ketophosphonate was prepared in 13 steps from (R) pantolactone using a synthesis based on a chelation controlled aldol condensation and an anti-selective reduction of a 3-hydroxyketone. Following the ketophosphonate-aldehyde reaction, selective deprotection followed by treatment with base effected the oxy-Michael reaction that gave the cis-2,6-disubstituted tetrahydropyran via thermodynamic control. Subsequent functional group manipulation led to the synthesis of a hydroxy ester that corresponded to the C1 C16 fragment of the bryostatins in 23 steps from (R)-pantolactone. The synthesis was repeated using slightly different protecting groups for a study of a ring closing metathesis approach to the bryostatins.

AB - Prenylation is a key post-translational reaction to increase the structural diversity and bioactivity of peptides and proteins. Until now, only one post translational modification enzyme, ComQ, has been identified to mediate the prenylation of a tryptophan residue in ribosomally synthesized peptides. Here, we report the in vitro characterization of KgpF, a novel prenyltransferase which transfers dimethylallyl moieties to tryptophan residues during kawaguchipeptin A biosynthesis. The stereospecific prenylation by KgpF was determined by a combination of in vitro dimethylallylation of Fmoc-tryptophan by KgpF and chemical synthesis of dimethylallylated Fmoc-tryptophan diastereomers. KgpF modified the tryptophan derivative with a dimethylallyl group at the 3 position of its indole ring, resulting in the formation of a tricyclic structure with the same scaffold as prenylation by ComQ, but with the opposite stereochemistry.

AB - An operationally simple method for the copper-mediated trifluoromethylthiolation of iodopyridinones employing (bpy)CuSCF3 (1; bpy = 2,2'-bipyridine) as a trifluoromethylthiolating reagent is presented. Various types of iodopyridinones are applicable and the trifluoromethylthiolated pyridinones are obtained in moderate to excellent yields. This method tolerates a variety of protecting groups on the nitrogen atom of pyridinones. In addition, scalability of the reaction is demonstrated. PMID- 27714216 TI - Ethionamide biomimetic activation and an unprecedented mechanism for its conversion into active and non-active metabolites. AB - Ethionamide (ETH), a second-line anti-tubercular drug that is regaining a lot of interest due to the increasing cases of drug-resistant tuberculosis, is a pro drug that requires an enzymatic activation step to become active and to exert its therapeutic effect. The enzyme responsible for ETH bioactivation in Mycobacterium tuberculosis is a monooxygenase (EthA) that uses flavin adenine dinucleotide (FAD) as a cofactor and is NADPH- and O2-dependant to exert its catalytic activity. In this work, we investigated the activation of ETH by various oxygen donor oxidants and the first biomimetic ETH activation methods were developed (KHSO5, H2O2, and m-CPBA). These simple oxidative systems, in the presence of ETH and NAD+, allowed the production of short-lived radical species and the first non enzymatic formation of active and non-active ETH metabolites. The intermediates and the final compounds of the activation pathway were well characterized. Based on these results, we postulated a consistent mechanism for ETH activation, not involving sulfinic acid as a precursor of the iminoyl radical, as proposed so far, but putting forward a novel reactivity for the S-oxide ethionamide intermediate. We proposed that ETH is first oxidized into S-oxide ethionamide, which then behaves as a "ketene-like" compound via a formal [2 + 2] cycloaddition reaction with peroxide to give a dioxetane intermediate. This unstable 4-membered intermediate in equilibrium with its open tautomeric form decomposes through different pathways, which would explain the formation of the iminoyl radical and also that of different metabolites observed for ETH oxidation, including the ETH NAD active adduct. The elucidation of this unprecedented ETH activation mechanism was supported by the application of isotopic labelling experiments. PMID- 27714217 TI - Design, synthesis and biological activities of new brassinosteroid analogues with a phenyl group in the side chain. AB - We have prepared and studied a series of new brassinosteroid derivatives with a p substituted phenyl group in the side chain. To obtain the best comparison between molecular docking and biological activities both types of brassinosteroids were synthesized; 6-ketones, 10 examples, and B-lactones, 8 examples. The phenyl group was introduced into the steroid skeleton by Horner-Wadsworth-Emmons. The docking studies were carried out using AutoDock Vina 1.05. Plant biological activities were established using different brassinosteroid bioassays in comparison with natural brassinosteroids. Differences in the production of the plant hormone ethylene were also observed in etiolated pea seedlings after treatment with new brassinosteroids. The most active compounds were lactone 8f and 6-oxo derivatives 8c and 9c, their biological activities were comparable or even better than naturally occurring brassinolide. Finally the cytotoxicity of the new derivatives was studied using human normal and cancer cell lines.

AB - A linear, chiron approach for the synthesis of C13-C24 fragments of cytostatic maltepolides A, C and D consisting of a tetrahydrofuran subunit and a chiral alkenyl/alkyl substituent is achieved from (+)-diethyl l-tartrate.

AB - A xanthene derivative containing a borinate moiety emitted red fluorescence with a high quantum yield. The interaction between the borinate and a sugar molecule induced a fluorescence change based on the change in the HOMO-LUMO gap. The response was pH-resistant in a wide range. In addition, catechol quenched through photoinduced electron transfer. The red fluorescence and polyol binding ability of dyes will pave the way for new biological applications of chemical sensors.

AB - Four different iridium(iii) polypyridyl complexes with varying excited state lifetimes are used as photocatalysts to study the effect of excited state lifetime on the rate of a prototypical photoredox-catalyzed reaction, the trifluoromethylation of quinoline. An improved mechanistic understanding of the photocatalysis is achieved, enabling guided optimization of reaction conditions and elucidating the role of the photocatalyst excited state lifetime on the rate of photocatalysis.

AB - Air-stable N-sulfonyl and N-phosphonyl DBN hexafluorophosphate salts have been synthesised under mild conditions as sulfonylating and phosphonylating agents. These salts are highly efficient in the sulfonylation and phosphonylation of a range of N- and O-nucleophiles to generate sulfonamides, sulfonate esters, phosphoramidates and phosphonate esters in good yields. PMID- 27714222 TI - Structure and biocatalytic scope of thermophilic flavin-dependent halogenase and flavin reductase enzymes. AB - Flavin-dependent halogenase (Fl-Hal) enzymes have been shown to halogenate a range of synthetic as well as natural aromatic compounds. The exquisite regioselectively of Fl-Hal enzymes can provide halogenated building blocks which are inaccessible using standard halogenation chemistries. Consequently, Fl-Hal are potentially useful biocatalysts for the chemoenzymatic synthesis of pharmaceuticals and other valuable products, which are derived from haloaromatic precursors. However, the application of Fl-Hal enzymes, in vitro, has been hampered by their poor catalytic activity and lack of stability. To overcome these issues, we identified a thermophilic tryptophan halogenase (Th-Hal), which has significantly improved catalytic activity and stability, compared with other Fl-Hal characterised to date. When used in combination with a thermostable flavin reductase, Th-Hal can efficiently halogenate a number of aromatic substrates. X ray crystal structures of Th-Hal, and the reductase partner (Th-Fre), provide insights into the factors that contribute to enzyme stability, which could guide the discovery and engineering of more robust and productive halogenase biocatalysts.

AB - A de novo protecting-group-free total synthesis of (+)-muricadienin, (+) ancepsenolide and (+)-3-hexadecyl-5-methylfuran-2(5H)-one has been achieved. Ring closing-metathesis has been the key step in the synthesis. In (+)-muricadienin synthesis, a long chain alkyl group has been installed by an sp-sp3 Sonogashira type reaction followed by a cis-selective Lindlar reduction. The total synthesis is achieved in 7 steps and in excellent 43.5% overall yield. Similarly, (+) ancepsenolide and (+)-3-hexadecyl-5-methylfuran-2(5H)-one synthesis is completed in 5 steps each and in 48 and 68% overall yields, respectively.

PMID- 27714225 TI - Acoustically propelled nanoshells. AB - Herein we report a new design for acoustic nanoswimmers, making use of a nanoshell geometry that was synthesized using a sphere template process. Such shell-shaped nanomotors display highly efficient acoustic propulsion on the nanoscale by converting energy from the ambient acoustic field into motion. The propulsion mechanism of the nanoshell motors relies on acoustic streaming stress over the asymmetric surface to produce the driving force for motion. The shell shaped nanomotors offer a high surface area to volume ratio, allow for efficient scalability and provide higher cargo towing capacity (in comparison to acoustically propelled nanowires). Furthermore, a detailed study of the parameters relevant to propulsion performance, including the material density, size and shape of the motors, reveals that the nanoshell motors exhibit a different propulsion behavior from that predicted by recent theoretical and experimental models for acoustically propelled nanomotors. Such findings indicate that further studies are needed to predict the behavior of acoustic nanomotors with different geometry designs. Practical applications of the new nanoshell motors, including "on-the-move" capture and the transport of multiple cargoes and internalization and movement inside live MCF-7 cancer cells, are demonstrated. These capabilities hold considerable promise for designing fuel-free nanoswimmers capable of performing complex tasks for diverse biomedical applications. PMID- 27714226 TI - Base-mediated one-pot synthesis of 1,2,4-oxadiazoles from nitriles, aldehydes and hydroxylamine hydrochloride without addition of extra oxidant. AB - A simple base-mediated one-pot synthesis of 3,5-disubstituted 1,2,4-oxadiazoles from nitriles, aldehydes and hydroxylamine hydrochloride has been developed, in which the aldehydes act as both substrates and oxidants. The reactions include three sequential procedures: base-promoted intermolecular addition of hydroxylamine to nitrile to lead to amidoxime, treatment of the amidoxime with an aldehyde to form 4,5-dihydro-1,2,4-oxadiazole, and oxidization of the 4,5-dihydro 1,2,4-oxadiazole by using another aldehyde to afford 1,2,4-oxadiazole. This method represents a direct and simple protocol for the synthesis of 3,5 disubstituted 1,2,4-oxadiazoles. PMID- 27714227 TI - Racemic and enantioselective metal-catalyzed synthesis of SF5-containing diarylmethanols. AB - The racemic and enantioselective metal-catalyzed addition of arylboronic acids to 4- and 3-(pentafluorosulfur)benzaldehydes is reported. The racemic synthesis was accomplished using a Pd-based system and a wide range of arylboronic acids could be used, resulting in yields of 42 to 98% of the corresponding SF5-containing diarylmethanols. A ruthenium-based system, along with (R,R)-Me-BIPAM as the chiral ligand, was investigated and optimized for the enantioselective version. In this case, while the chiral SF5-containing diarylmethanols were generally obtained in good yields (up to 94%) and enantioselectivities (up to 98% ee), limitations were also observed. For instance, 4-(pentafluorosulfur)benzaldehyde generally provided slightly better yields than 3-(pentafluorosulfur)benzaldehyde. In addition, lower yields and enantioselectivities were observed when using either 4- and 3-substituted arylboronic acids bearing electron-withdrawing (e.g., CO2Et, NO2, CF3) or 2-substituted arylboronic acids (regardless of the nature of the substituent). Overall, the SF5-containing diarylmethanols described herein represent novel and potentially useful fluorinated building blocks for the synthesis of biologically active compounds. PMID- 27714228 TI - Titania-coated gold nanorods with expanded photocatalytic response. Enzyme-like glucose oxidation under near-infrared illumination. AB - Gold nanorods coated with a uniform titanium dioxide nanoshell have been prepared and used as glucose-oxidase surrogates. Remarkably, this core-shell photocatalytic nanostructure has been able to induce complete oxidation of glucose at near room temperature (32-34 degrees C) in a wide range of pH values with the aid of a near-infrared (NIR) irradiation source. In contrast, the uncoated gold nanorods exhibit negligible photo-oxidation response under identical experimental conditions thereby proving the photoactivity of the titania shell towards glucose oxidation. The process takes place via in situ photo-generation of singlet oxygen or hydroxyl radicals as reactive oxidative species (ROS). This underlines the role played by the core nanorods as plasmonic light harvesters in the NIR range and constitutes the first example of a NIR activated enzyme-like catalyst.

AB - Two new norditerpenoids, miltiolactones A and B (1a, 1b); seven new neolignans, miltiolignanolides A-G (2a, 2b and 3a, 3b and 4a, 4b, and 5) were obtained from the root extract of Salvia miltiorrhiza. Using HPLC separation with a chiral column, compounds 1-4 were found to exist as four pairs of enantiomers. Compounds 2-5 are novel neolignans with a dibenzocycloheptatriene ring system, which form an unprecedented 6/7/6 carbon skeleton. The structures were established via extensive spectroscopic analysis, and experimental and calculated electronic circular dichroism (ECD) spectra, and compound 1 was also elucidated by X-ray diffraction experiments. Compounds 2a and 2b significantly increased the viability of H9c2 cells from H2O2-induced cell death, and 3a showed significant antioxidant activity in an ABTS assay. In addition, compounds 2a, 2b and 3a, 3b display moderate inhibitory effects on nitric oxide (NO) production in LPS induced microglial cells.

AB - Herein, we report a simple fluoride-mediated reaction for the direct mono- and dialkylthio-functionalization of unsubstituted perylenediimides (PDIs) under very mild conditions. The aromatic substitution reaction offers the possibility to introduce primary, secondary and, even, tertiary alkanethiols either on the 1- or on the 1,6-bay positions of unsubstituted PDIs. 1,6-DialkylthioPDIs show that absorption and fluorescence spectra shifted to the red when compared with the unsubstituted PDI, with Stokes shifts around 70-80 nm.

With various substituents on the substrates, the reaction proceeded smoothly to give the corresponding products in good to excellent yields.

PMID- 27714232 TI - Carbocation-pi interaction: evaluation of the stabilization by phenylalanine of a biochemical carbocation intermediate. AB - Computational analyses, using primarily density functional theory, have been used to determine the stabilization associated with the carbocation-pi interaction of a biochemical carbocation intermediate binding to a phenylalanine residue in an enzyme active site. Studies of complexation between t-butyl cation and ethylbenzene, and of a model of a carbocation intermediate with a phenylalanine in the active site of geranyl diphosphate C-methyl transferase, have afforded the first quantitative evaluation of the stabilization that can be provided to a carbocation by an aromatic residue in an enzymatic reaction. Describing the hydrophobic surrounding medium using a dielectric constant between epsilon = 2 and epsilon = 4, the calculated carbocation-pi stabilization energy lies in the range of 10-7.5 kcal mol-1.

AB - Several of the lowest energy structures of small and medium sized boron clusters are two-dimensional systems made up of a pair of concentric rings. In some cases, the barriers to the rotation of one of those rings relative to the other are remarkably low. We find that a combination of electronic and geometrical factors, including apparently the relative sizes and symmetries of the inner and outer rings, are decisive for the diminished barriers to in-plane rotation in these two dimensional clusters. A sufficiently large outer ring is important; for instance, expansion of the outer ring by a single atom may reduce the barrier significantly. A crucial factor for an apparent rotation is that the sigma skeleton of the individual rings remains essentially intact during the rotation. Finally, the transition state for the rotation of the inner ring comprises the transformation of a square into a diamond, which may be linked to a mechanism suggested decades ago for the isomerization of carboranes and boranes.

This eventually leads to higher compacted DNA aggregates which are important for gene transfection.

The advent of deoxyribo- and ribopentose-sugars, nucleosides, nucleotides and oligonucleotides in the prebiotic soup is briefly discussed. Further, the formation of early single stranded oligomers, base-pairing possibilities and information transfer based on the stability parameters of the derived duplexes is reviewed. Each theory has its own merits and demerits which we have elaborated upon. Lastly, using clues from this literature, a possible explanation for the specific 3'-5'-linkages in RNA is proposed. PMID- 27714239 TI - Tetrazolone as an acid bioisostere: application to marketed drugs containing a carboxylic acid. AB - Matched molecular pair analysis was used to evaluate the ability of a tetrazolone group to act as a bioisostere of a carboxylic acid. Compound 7, a tetrazolone of the anti-hypertensive drug, telmisartan 6, was shown to be a potent AT1 antagonist (Kb = 0.14 nM), with activity comparable to telmisartan itself (Kb = 0.44 nM). Additionally, compound 9, a tetrazolone congener of the marketed anti cancer agent, bexarotene 8, was shown to be an agonist at the retinoid X receptor alpha (EC50 = 64 nM). Compounds containing a tetrazolone group showed similar microsomal stability and plasma protein binding to marketed acid counterparts, while also reducing the value for clog P. Furthermore, compound 7 displayed an improved rat pharmacokinetic profile cf. telmisartan 6. Taken together, the results demonstrate that a tetrazolone group may serve as a bioisostere for a carboxylic acid.

AB - Alkynyl ethers and alkynyl thioethers ('ynol ethers' and 'thioynol ethers') are appealing building-blocks in synthetic chemistry due to their ease of manipulation and predictable reactivity. Until recently however, their potential has remained underexploited due to difficulties in preparation and isolation. Although recent advances in synthetic chemistry have highlighted various applications for ynol ethers, the equivalent thioynol examples have been rather less exploited despite a unique and fascinating reactivity profile. Although superficially the chemistry of alkynyl ethers and their sulfide counterparts are similar, close examination of their chemistry reveals important differences which can be exploited by the synthetic chemist. This review will examine the preparation of both classes of compound and examine their reactivity to highlight their powerful synthetic applications. Particular focus will be made of thiynol ethers whose chemistry exhibits some fascinating differences compared to their oxygen counterparts and have immense untapped potential for synthetic chemistry.

PMID- 27714243 TI - Inhibitory properties of 1,4-dideoxy-1,4-imino-d-arabinitol (DAB) derivatives acting on glycogen metabolising enzymes. AB - Glycogen synthase (GS) and glycogen phosphorylase (GP) are the key enzymes that control, respectively, the synthesis and degradation of glycogen, a multi branched glucose polymer that serves as a form of energy storage in bacteria, fungi and animals. An abnormal glycogen metabolism is associated with several human diseases. Thus, GS and GP constitute adequate pharmacological targets to modulate cellular glycogen levels by means of their selective inhibition. The compound 1,4-dideoxy-1,4-imino-d-arabinitol (DAB) is a known potent inhibitor of GP. We studied the inhibitory effect of DAB, its enantiomer LAB, and 29 DAB derivatives on the activity of rat muscle glycogen phosphorylase (RMGP) and E. coli glycogen synthase (EcGS). The isoform 4 of sucrose synthase (SuSy4) from Solanum tuberosum L. was also included in the study for comparative purposes. Although these three enzymes possess highly conserved catalytic site architectures, the DAB derivatives analysed showed extremely diverse inhibitory potential. Subtle changes in the positions of crucial residues in their active sites are sufficient to discriminate among the structural differences of the tested inhibitors. For the two Leloir-type enzymes, EcGS and SuSy4, which use sugar nucleotides as donors, the inhibitory potency of the compounds analysed was synergistically enhanced by more than three orders of magnitude in the presence of ADP and UDP, respectively. Our results are consistent with a model in which these compounds bind to the subsite in the active centre of the enzymes that is normally occupied by the glucosyl residue which is transferred between donor and acceptor substrates. The ability to selectively inhibit the catalytic activity of the key enzymes of the glycogen metabolism may represent a new approach for the treatment of disorders of the glycogen metabolism. PMID- 27714244 TI - Can the analyte-triggered asymmetric autocatalytic Soai reaction serve as a universal analytical tool for measuring enantiopurity and assigning absolute configuration? AB - An investigation is reported on the use of the autocatalytic enantioselective Soai reaction, known to be influenced by the presence of a wide variety of chiral materials, as a generic tool for measuring the enantiopurity and absolute configuration of any substance. Good generality for the reaction across a small group of test analytes was observed, consistent with literature reports suggesting a diversity of compound types that can influence the stereochemical outcome of this reaction. Some trends in the absolute sense of stereochemical enrichment were noted, suggesting the possible utility of the approach for assigning absolute configuration to unknown compounds, by analogy to closely related species with known outcomes. Considerable variation was observed in the triggering strength of different enantiopure materials, an undesirable characteristic when dealing with mixtures containing minor impurities with strong triggering strength in the presence of major components with weak triggering strength. A strong tendency of the reaction toward an 'all or none' type of behavior makes the reaction most sensitive for detecting enantioenrichment close to zero. Consequently, the ability to discern modest from excellent enantioselectivity was relatively poor. While these properties limit the ability to obtain precise enantiopurity measurements in a simple single addition experiment, prospects may exist for more complex experimental setups that may potentially offer improved performance. PMID- 27714245 TI - Groove modification of siRNA duplexes to elucidate siRNA-protein interactions using 7-bromo-7-deazaadenosine and 3-bromo-3-deazaadenosine as chemical probes. AB - Elucidation of dynamic interactions between RNA and proteins is essential for understanding the biological processes regulated by RNA, such as RNA interference (RNAi). In this study, the logical chemical probes, comprising 7-bromo-7 deazaadenosine (Br7C7A) and 3-bromo-3-deazaadenosine (Br3C3A), to investigate small interfering RNA (siRNA)-RNAi related protein interactions, were developed. The bromo substituents of Br7C7A and Br3C3A are expected to be located in the major and the minor grooves, respectively, and to act as a steric hindrance in each groove when these chemical probes are incorporated into siRNAs. A comprehensive investigation using siRNAs containing these chemical probes revealed that (i) Br3C3A(s) at the 5'-end of the passenger strand enhanced their RNAi activity, and (ii) the direction of RISC assembly is determined by the interaction between Argonaute2, which is the main component of RISC, and siRNA in the minor groove near the 5'-end of the passenger strand. Utilization of these chemical probes enables the investigation of the dynamic interactions between RNA and proteins.

PMID- 27714247 TI - Strain-promoted azide-alkyne cycloaddition for protein-protein coupling in the formation of a bis-hemoglobin as a copper-free oxygen carrier. AB - Conventional chemical approaches to protein-protein coupling present challenges due to the intrinsic competition between the desired interactions of reagents with groups of the protein as well as reactions with water. Biorthogonal Cu(i) catalyzed azide-alkyne cycloaddition (CuAAC)-processes provide a basis to direct reactivity without functional group interference. However, the requirement for Cu(i) in CuAAC leads to complications that result from the metal ion's interactions with the protein. In principle, a similar but metal-free alternative approach to coupling could employ the reaction of an alkyne that is strained in combination with an azide (strain-promoted azide-alkyne cycloaddition, SPAAC). The method is exemplified by the combination of a cyclooctyne derivative of hemoglobin with an azide-modified hemoglobin. The bis-hemoglobin tetramer that is produced has properties consistent with those sought for use as a hemoglobin based oxygen carrier (HBOC).

For this purpose, the fluorescence, singlet oxygen and photodegradation quantum yields and fluorescence lifetime values of the compounds were determined in DMSO solutions. The phototoxicity and cytotoxicity of the systems were studied against the cervical cancer cell line named HeLa for an evaluation of their suitability for photodynamic therapy. The results showed that a maximum of 80% of HeLa cells were killed following light irradiation with photodynamic efficiency. All of the results showed that the novel activatable molecular beacons could be suitable candidates for cancer treatment via PDT technique.

AB - Samarium diiodide-water (SmI2-H2O) reagents have emerged as some of the most practical systems enabling reduction and reductive cyclizations of ketyl radicals. Recently, this reaction manifold has been extended to acyl-type radicals generated from cyclic polar carboxylic acid derivatives. However, the relationship between the fundamental electron- and proton-transfer steps in the generation of ketyl-type radicals with SmI2-H2O remains unclear. An intriguing scenario involves an initial proton-coupled electron transfer (PCET) mechanism from SmI2-H2O to the carbonyl group. Herein, we calculate with high accuracy bond dissociation free energies (BDFE) for the O-H bond in ketyl radicals in 14 cyclic and acyclic ketone, ester, imide and amide substrates and in anthracene relevant to reductions with SmI2-H2O and quantitatively assess the feasibility of concerted PCET in the reduction of carbonyl groups using SmI2-H2O. Reduction potentials of all substrates have been calculated. The data argue against concerted PCET from SmI2-H2O to carbonyl substrates.

AB - Sialic acids (Sias) are important terminal sugars on cell surfaces involved in a wide range of protein-carbohydrate interactions. Hence, agents modulating sias mediated protein interactions are promising inhibitors or vaccine candidates. Here, we report the synthesis of Neu5Acalpha(2-6)Gal structural analogs and their binding to a series of siglecs. The results showed distinct binding patterns with conserved siglecs (hCD22 and mCD22) compared to rapid evolving siglecs (Siglecs 3 & -10). PMID- 27714251 TI - Developments toward the synthesis and application of 3-hydroxyindanones. AB - 3-Hydroxyindanone is an important scaffold in many natural products, biologically active compounds, and functional materials. This review provides a comprehensive overview of the construction of 3-hydroxyindanone derivatives and their applications towards pharmaceutically promising drug candidates. The total synthesis of the complex natural products containing this simple core is discussed. The highlights of the literature from 1948 to 2015 are comprised. PMID- 27714252 TI - A protecting group-free synthesis of (-)-hortonones A-C from the Inhoffen-Lythgoe diol. AB - A synthesis of hortonones A-C has been accomplished from vitamin D2via the Inhoffen-Lythgoe diol without the use of protective groups. Key steps in the syntheses include a TMS-diazomethane mediated regioselective homologation of the cyclohexanone ring to a cycloheptanone moiety and a sodium naphthalenide-mediated allylic alcohol transposition. It has been found that the absolute configuration of the natural hortonones is opposite that of the synthetic material prepared from vitamin D2. PMID- 27714253 TI - A halogen bond does not dictate the conformational preferences of cis-1,3 disubstituted cyclohexanes. AB - Halogen bonds are defined as interactions between halogens and a Lewis base in which the halogen (X) acts as the electrophilic species, and is typically explained by the presence of a sigma-hole at the end of the C-X bond. Despite the important role of the halogen bond in intermolecularly interacting species, e.g. in acid-base reactions, enzyme inhibition and the supramolecular architecture, this interaction was not found to control the conformational equilibrium of some small model molecules, namely cis-1,3-disubstituted cyclohexanes. In addition, the attraction between the electrophilic (sigma-hole) and nucleophilic regions is used to explain that the halogen bond was weaker than that in the species with parallel C-X bonds. Therefore, intramolecular halogen bonds should be used with caution to explain the conformational stability of organic compounds.

AB - The development of new methods for the rapid assembly of spirocyclic frameworks with high molecular complexity is always of great importance for organic syntheses. In this perspective, we endeavour to cover the recent achievements from our group in the construction of synthetically valuable spirocyclohexadienones from easily accessible phenol-derived biaryls using a transition-metal-catalyzed C-H activation/dearomatization strategy. The key feature of these cooperative reactions is the simultaneous C-H bond activation and aromaticity disruption, leading to the formation of various spirocyclic molecules that are difficult or inaccessible using conventional approaches. PMID- 27714255 TI - Total synthesis of diptoindonesin G and its analogues as selective modulators of estrogen receptors. AB - We have developed a versatile synthetic strategy for the synthesis of the natural product diptoindonesin G and its analogues as selective modulators of estrogen receptors. The strategy involves a regioselective dehydrative cyclization of arylacetals, a regioselective bromination of benzofurans, a sequential cross coupling of bromo-benzofurans with aryl boronic acids, and a BBr3-mediated tandem cyclization and demethylation. Preliminary biological studies uncovered the critical and dispensable phenolic hydroxyl groups in the natural product and also revealed unexpected selectivity for isoforms of estrogen receptor. PMID- 27714256 TI - Magnesium salt promoted tandem nucleophilic addition-Oppenauer oxidation of aldehydes with organozinc reagents. AB - A magnesium salt promoted synthesis of ketones via tandem nucleophilic addition Oppenauer oxidation of aldehydes using organozinc chemistry was demonstrated. Magnesium salts concomitantly generated via magnesium metal mediated organohalide zincation exhibit high efficacy for nucleophilic addition of organozinc reagents to aromatic aldehydes and thereafter Oppenauer oxidation whereby ketones are formed in high to excellent yields. PMID- 27714258 TI - Comment on "Formation of polyelectrolyte multilayers: ionic strengths and growth regimes" by K. Tang and A. M. Besseling, Soft Matter, 2016, 12, 1032. AB - Tang and Besseling recently published a study on the growth of polyelectrolyte multilayers formed by poly(diallyl-dimethylammonium chloride), PDADMAC, and the sodium salt of poly(4-styrenesulfonate), PSSNa. They described the different growth regimes appearing in the (PDADMAC + PSS)n multilayers within a scenario in which the appearance of interdiffusion of the polyelectrolyte chains within the multilayer architecture plays a central role in the transition between the different regimes. However, this account contrasts, without an apparent explanation, with previous experimental evidence reported in the literature. PMID- 27714257 TI - New synthetic approaches towards analogues of bedaquiline. AB - Multi-drug resistant tuberculosis (MDR-TB) is of growing global concern and threatens to undermine increasing efforts to control the worldwide spread of tuberculosis (TB). Bedaquiline has recently emerged as a new drug developed to specifically treat MDR-TB. Despite being highly effective as a result of its unique mode of action, bedaquiline has been associated with significant toxicities and as such, safety concerns are limiting its clinical use. In order to access pharmaceutical agents that exhibit an improved safety profile for the treatment of MDR-TB, new synthetic pathways to facilitate the preparation of bedaquiline and analogues thereof have been discovered. PMID- 27714259 TI - Chemoselective photooxygenations of furans bearing unprotected amines: their use in alkaloid synthesis. AB - Very recent investigations are described, which have shown how basic and unprotected nitrogen functionalities can be included, problem-free, in the furan photooxidation step of singlet oxygen-initiated cascade reaction sequences. The amine groups do not react with singlet oxygen, but, instead, participate later on in the sequences that ultimately yield a diverse range of important alkaloid motifs. To illustrate the versatility of this chemistry, six natural products were synthesised very rapidly and efficiently. Furthermore, all the new technologies operated under green conditions and without the use of a single protecting group. PMID- 27714260 TI - The excitation intensity dependence of singlet fission dynamics of a rubrene microcrystal studied by femtosecond transient microspectroscopy. AB - We have investigated the excitation intensity dependence of the singlet fission in a crystalline rubrene by means of femtosecond transient absorption microspectroscopy. When a rubrene microcrystal was excited to higher energy levels than that of the lowest singlet excited (S1) state with a 397 nm femtosecond laser pulse, a triplet excited state was formed through two pathways of the singlet fission, i.e. the direct fission from higher vibrational levels of the S1 state with a time constant of 2.2 ps and the thermally activated fission from the S1 state in a few tens of ps. The time constant of the thermally activated fission changed from 35 to 17 ps for increasing of the laser fluence from 0.65 to 18 mJ cm-2 per pulse, although that of the direct fission was constant with the excitation laser intensity. On the other hand, the yield of the triplet formation was independent of the intensity. We also examined the temperature dependence of the singlet fission and demonstrated the activation energy of the thermally activated fission to be 0.21 eV. Based on the experimental results, we considered the excitation intensity dependence of the singlet fission of the rubrene crystal in terms of the effect of transient local heating on a ps time scale after femtosecond laser excitation owing to the nonradiative vibrational relaxation from the higher vibrational level to the lower one in the S1 state. PMID- 27714261 TI - A near-infrared fluorescent probe based on chloroacetate modified naphthofluorescein for selectively detecting cysteine/homocysteine and its application in living cells. AB - We have prepared a near-infrared (NIR) turn-on fluorescent probe (NFC) based on chloroacetate modified naphthofluorescein for specific detection of cysteine (Cys) and homocysteine (Hcy) over glutathione (GSH) and other amino acids (AAs) with the detection limits of 0.30 MUM and 0.42 MUM, respectively. The fluorescence intensity of the naphthofluorescein (NF) chromophore is modulated by an internal charge transfer (ICT) process. The probe NFC is readily available and weakly fluorescent, but of observably enhanced fluorescence after reacting with Cys or Hcy. We assumed and then demonstrated that the fluorescence off-on process involves a conjugate nucleophilic substitution/cyclization sequence. Furthermore, the probe has been successfully applied for detecting the total content of Cys and Hcy in human plasma and imaging in living cells with low toxicity. PMID- 27714262 TI - Synthesis of furostanol glycosides: discovery of a potent alpha-glucosidase inhibitor. AB - A convenient approach to the synthesis of furostanol glycosides has been developed with the features of both highly efficient incorporation of a 26-O-beta d-glucopyranosyl unit and ready formation of hemiketal ring E. The total syntheses of seven furostanol saponins including funlioside B, lilioglycoside, protobioside I, protodioscin, pallidifloside I, coreajaponins A and parisaponin I are efficiently achieved using an easily available 16beta-acetoxy-22-oxo-26 hydroxy-cholestanic derivative as a powerful building block. The alpha glucosidase inhibitory activity of the synthesized saponins is also evaluated, which reveals that funlioside B is a highly potential lead for developing alpha glucosidase inhibitors. PMID- 27714263 TI - Formation and flow behavior of micellar membranes in a T-shaped microchannel. AB - Understanding the formation and instability behavior of membranes is of fundamental interest and practical relevance to various biotechnological applications and self-assembly systems. Surfactant micellar membranes serve as a simple model system when surfactant molecules self-assemble into micellar structures under flow, but observing such process in real time is a major challenge due to limitations in spatiotemporal resolutions. We use a simple T shaped microchannel to capture the formation and flow behavior of an ionic surfactant micro-micellar-membrane (MUMM) when an aqueous stream of organic salt sodium salicylate (NaSal) meets a stream of cationic surfactant cetyltrimethylammonium bromide (CTAB). The MUMM is shown to grow and become unstable depending on the flow rate, as characterized using micro-particle image velocimetry, fluorescence microscopy, flow birefringence, and bulk rheometry. We propose a simple model that accounts for the flow, elasticity and inertia of the MUMM to analyze its flow behavior. Our experimental protocol can be easily replicated in conventional laboratories without the need of utilizing sophisticated equipment such as synchrotron small angle X-ray scattering and micro-electronics circuits. Our combined experimental and modeling results can be extrapolated to provide new insights to study the flow behavior and thermodynamic phases of lipid membranes, membrane proteins, and biological membranes. PMID- 27714264 TI - Topical treatment of green tea polyphenols emulsified in carboxymethyl cellulose protects against acute ultraviolet light B-induced photodamage in hairless mice. AB - Ultraviolet (UV) radiation causes skin injury and inflammation resulting in impaired immune response and increased risk of skin cancer. It has been shown that green tea polyphenols (GTPs) enhanced intracellular antioxidant defense and promoted the downregulation of proapoptotic genes, and they could be used to protect against the damage induced by UV irradiation. However, the high instability and poor bioavailability of GTPs impose restrictions on their potential pharmacological use. Here we show that carboxymethyl cellulose sodium (CMC-Na) had a stabilizing effect on GTPs under aqueous conditions and topical application of GTPs (emulsified in CMC-Na) had a strong photoprotective effect against acute UVB induced photodamage in uncovered (Uncv) hairless mice skin. After 8 h of incubation at 50 degrees C with CMC-Na, a percentage i.e. 93% of GTPs was preserved, while in the absence of CMC-Na, a percentage of only 61% was preserved. Topical treatment of emulsified GTPs effectively inhibited acute UVB induced infiltration of inflammatory cells, increase of skin thickness, oxidative stress such as depletion of antioxidant enzymes and lipid oxidation, and induced nuclear accumulation of Nrf2 in the mice skin. We also discovered the ability of GTPs to simultaneously trigger accumulation of nuclear Nrf2 and export of nuclear Bach1. Altogether, our findings reinforced the putative application of GTPs in the prevention/minimization of the deleterious effects of UV on the skin.

AB - A novel cyclic N-phosphoryl ketimine structure can efficiently react with olefins as useful directing groups to construct a myriad of phosphate scaffolds via rhodium(iii)-catalyzed ortho-alkenylation. This method provides a probability that the coupling products could be used as a building block to access more complex organic phosphorus compounds. PMID- 27714267 TI - An expeditious synthesis of the ascomycete metabolite rigidiusculamide B. AB - The ascomycete metabolite rigidiusculamide B was synthesised in six steps and 22% overall yield. The key steps were a Li2Te-triggered Dittmer-type Dieckmann cyclisation of an N-(alpha-haloacyl)tyrosine ester to give a 4-O-silyl tetramate, followed by its fluoride-assisted desilylation-oxidation with oxygen. The product 3-hydroxy-pyrrolidine-2,4-dione was obtained as a 6 : 1 mixture of separable diastereoisomers. PMID- 27714268 TI - Biphenyl urea derivatives as selective CYP1B1 inhibitors. AB - Highly selective CYP1B1 inhibitors have potential in the treatment of hormone induced breast and prostate cancers. Mimicry of potent and selective CYP1B1 inhibitors, alpha-naphthoflavone and stilbenes, revealed that two sets of hydrophobic clusters suitably linked via a polar linker could be implanted into a new scaffold 'biphenyl ureas' to create potentially a new class of CYP1B1 inhibitors. A series of sixteen biphenyl ureas were synthesized and screened for CYP1B1 and CYP1A1 inhibition in SacchrosomesTM, yeast-derived recombinant microsomal enzymes. The most active human CYP1B1 inhibitors were further studied for their selectivity against human CYP1A1, CYP1A2, CYP3A4 and CYP2D6 enzymes. The meta-chloro-substituted biphenyl urea 5h was the most potent inhibitor of CYP1B1 with IC50 value of 5 nM. It displayed excellent selectivity over CYP1A1, CYP1A2, CYP3A4 and CYP2D6 (IC50 >10 MUM in the four CYP assays, indicating >2000 fold selectivity). Similarly, two methoxy-substituted biphenyl ureas 5d and 5e also displayed potent and selective inhibition of CYP1B1 with IC50 values of 69 and 58 nM, respectively, showing >62 and >98-fold selectivity over CYP1A1, CYP1A2, CYP3A4 and CYP2D6 enzymes. In order to probe if the relatively insoluble biphenyl ureas were cell permeable and if they could at all be used for future cellular studies, their CYP1B1 inhibition was investigated in live recombinant human and yeast cells. Compound 5d displayed the most potent inhibition with IC50s of 20 nM and 235 nM, respectively, in the two cell-based assays. The most potent and selective CYP1B1 inhibitor (compound 5h) from Sacchrosomes, also displayed potent inhibition in live cell assays. Molecular modeling was performed to understand the trends in potency and selectivity observed in the panel of five CYP isoenzymes used for the in vitro studies. PMID- 27714269 TI - Phosphorylated cyclopropanes in the synthesis of alpha-alkylidene-gamma butyrolactones: total synthesis of (+/-)-savinin, (+/-)-gadain and (+/-) peperomin E. AB - Phosphorylated cyclopropanes, generated via the Rh(ii)-catalysed intramolecular cyclopropanation of alpha-(diethoxyphosphoryl)acetates, have been found to be useful precursors in the synthesis of alpha-alkylidene-gamma-butyrolactones. These cyclopropyl intermediates undergo regioselective reductive ring-opening and subsequent Horner-Wadsworth-Emmons olefination to complete the synthesis. Total syntheses of (+/-)-savinin and (+/-)-gadain, as well as the first total synthesis of (+/-)-peperomin E, are all described using this method. PMID- 27714270 TI - Synthesis of novel styryl-N-isopropyl-9H-carbazoles for designing trans conjugated regular silicon hybrid materials. AB - An efficient synthesis and characterization of several new, conjugated styryl carbazole compounds functionalized by monovinylsilanes in a stereocontrolled approach is presented. All N-organic derivatives were successfully examined in silylative coupling in the presence of ruthenium-hydride complexes 4 and 5. Furthermore, a novel class of vinylene-arylene linear oligomeric materials with 1,4-bis(dimethylvinylsilyl)naphthalene in the main chain was produced. Both reactions proceed very effectively, stereo- and regioselectively, allowing one to obtain E-isomer derivatives with high isolation yields. PMID- 27714271 TI - Radiation damage to single stranded oligonucleotide trimers labelled with 5 iodopyrimidines. AB - The radiolysis of deoxygenated aqueous solution containing trimeric oligonucleotides labelled with iodinated pyrimidines and Tris-HCl as the hydroxyl radical scavenger leads to electron attachment to the halogenated bases that mainly results in single strand breaks. The iodinated trimers are 2-fold more sensitive to solvated electrons than the brominated oligonucleotides, which is explained by the barrier-free dissociation of the iodinated base anions. The present study fills the literature gap concerning the chemistry triggered by ionizing radiation in the iodinated pyrimidines incorporated into DNA. PMID- 27714272 TI - Iron(iii) chloride hexahydrate-promoted selective hydroxylation and chlorination of benzyl ketone derivatives for the construction of hetero-quaternary scaffolds. AB - A novel and tunable alpha-hydroxylation/alpha-chlorination of benzyl ketone derivatives has been developed for the construction of hetero-quaternary carbon centers by iron(iii) chloride hexahydrate mediated selective transformations through the application of different oxidants, especially the crystal water in the catalyst as an OH source is firstly reported in this hydroxylation. PMID- 27714273 TI - Computation-guided improved one-pot synthesis of macrocyclic cation-binding aromatic pyridone pentamers. AB - By using polar DMF to relax the H-bonded rigid backbone and to lower the energetic penalty associated with the sterically-crowded environment, the yields for BOP-mediated one-pot synthesis of pentameric macrocycles can be improved from 10-25% as obtained in CH2Cl2 to 13-47% when 15% DMF in CH2Cl2 was used as the reaction medium. PMID- 27714274 TI - Enantioselective synthesis of alpha,alpha-disubstituted alpha-amino acids via direct catalytic asymmetric addition of acetonitrile to alpha-iminoesters. AB - alpha,alpha-Disubstituted alpha-amino acids have attracted increasing interest due to their potential utility as building blocks of unnatural peptides. Herein we document an enantioselective entry to this class of compounds through the direct catalytic addition of acetonitrile to alpha-iminoesters bearing an N thiophosphinoyl group. Chiral N-heterocyclic carbene complexes of [Ir(cod)(OMe)]2 catalytically rendered the catalytic generation of alpha-cyanocarbanions from acetonitrile in combination with Barton's base, followed by enantioselective addition to the imino carbonyl group, delivering a variety of enantioenriched alpha-cyanomethylated alpha,alpha-disubstituted alpha-amino acid derivatives. PMID- 27714275 TI - Photocatalytic degradation of ibuprofen using TiO2 sensitized by Ru(ii) polyaza complexes. AB - In this work, modification of TiO2 was carried out by incorporation of two novel Ru(ii) polyaza complexes. The N1-(2-aminobenzyliden)-N2,N2-bis(2-(2 aminobenzyliden)aminoethyl)ethane-1,2-diaminoruthenium(ii) and N1,N2-bis(2 aminobenziliden)ethane-1,2-diaminoruthenium(ii) complexes were synthesized via metal-ligand direct reaction. The complexes were characterized by UV-Vis, FTIR and fluorescence spectroscopy, and the chemical composition was obtained from elemental analysis by the combustion method; additionally, the sensitized TiO2 catalysts were also characterized by XRD, SEM and diffuse reflectance techniques. The photocatalytic activity of the prepared catalysts was tested in a batch reactor under visible radiation for the degradation of ibuprofen in aqueous solution. The evolution of the drug degradation process was evaluated by high performance liquid chromatography (HPLC), while the mineralization percentage was monitored by the determination of total organic carbon (TOC). The results indicated that the incorporation of these complexes improves the activation of TiO2 under visible light, increasing the degradation and mineralization percentage of ibuprofen up to 35% compared to the unmodified material, thereby making it suitable for application in heterogeneous photocatalysis of the said pharmaceutical in aqueous media using visible light as the energy source. PMID- 27714276 TI - Temperature-boosted photocatalytic H2 production and charge transfer kinetics on TiO2 under UV and visible light. AB - This study investigates the effect of reaction temperature (298-353 K) on photocatalytic H2 production in bare and platinized TiO2 (Pt/TiO2) suspensions containing various organic hole scavengers (EDTA, methanol, and formic acid) under UV (lambda > 320 nm) and visible light (lambda > 420 nm for ligand-to-metal charge transfer). H2 production rates are enhanced ~7.8- and ~2.5-fold in TiO2 and Pt/TiO2 suspensions, respectively, with EDTA under UV by simply elevating the reaction temperature from 298 K to 323 K (DeltaT = 25 degrees C). Such a temperature-boosted increase in H2 production is always observed, regardless of the TiO2 crystalline structure (anatase, rutile, and an anatase/rutile mixture), type of hole scavenger, and irradiation wavelength range. It is estimated that approximately 90% of incident photons are utilized in H2 production, for which the activation energy is 25.5 kJ mol-1. Detailed photoelectrochemical analyses show the positive relationship between reaction temperature and photocurrent generation, with charge carrier mobility and interfacial charge transfer improving at higher temperatures. Other possible factors, such as H2 solubility and mass transport, play a limited role. PMID- 27714277 TI - Spontaneous exfoliation of a drying gel. AB - Wet starch cracks when it dries inhomogeneously, while hot glass cracks when it cools non-uniformly. In both cases, differential shrinkage induced by drying/cooling from the surface causes superficial cracks to grow perpendicular to the surface in different patterns. In contrast with these observations of bulk cracking in brittle materials, when a soft and homogeneously swollen polymer gel dries, differential strains lead to the peeling of a thin layer that spontaneously tears away from the bulk. Continued drying leads to the process repeating itself, forming a peeled-layered structure. The emergent thickness of the exfoliated layer is a function of both the geometry of the original gel and the physical parameters associated with the drying rate and external temperature. We characterize the experimental conditions under which layer peeling can arise, and use simulations to corroborate these observations. Finally, a minimal theory explains the scaling of the peel thickness, consistent with our experiments. PMID- 27714278 TI - Radical-radical cross coupling reactions of photo-excited fluorenones. AB - Radical-radical cross coupling reactions of photoexcited 9-fluorenones have been accomplished for the first time, leading to the synthesis of 9-alkyl, pyrollidinyl and spiro-THF derivatives of 9-fluorenones. The method also reveals, for the first time, the behaviour of ketyl radicals in decarboxyaltive alkylation and ring expansion reactions. PMID- 27714279 TI - Lipid structure influences the ability of glucose monocorynomycolate to signal through Mincle. AB - Mincle (macrophage-inducible C-type lectin) is a C-type lectin receptor that provides the capacity for immune sensing of a range of pathogen- and commensal derived glycolipids. Mincle can recognize mycolic and/or corynomycolic acid esters of trehalose, glycerol and glucose from mycobacteria and corynebacteria. While simple straight-chain long fatty acids (e.g. behenic acid) can substitute for mycolic acid on trehalose and glycerol and maintain robust signalling through Mincle, glucose monobehenate has been reported to be much less active than glucose monocorynomycolate (GMCM). We report the preparation of a range of analogues of GMCM to explore structural requirements in the lipid chain for signalling through Mincle. GMCM analogues bearing simple straight chain or branched fatty acid esters provided only weak signalling through human and mouse Mincle. A GMCM variant with a truncated (pentyl) alpha-chain provided attenuated signalling, whereas an analogue with an extended (tricosyl; C23) alpha-chain signalled as potently as GMCM. This work suggests that Mincle has the ability to survey mycolate-derived glycolipids from actinomycetes, distinguishing non pathogenic (e.g. Rhodococcus spp.) and pathogenic (e.g. Mycobacterium tuberculosis) species on the basis of alpha-chain length. Finally, an alpha phenyldodecyl analogue of GMCM possessed similar potency to GMCM and was only slightly less potent than trehalose dimycolate (cord factor), showing that large functional groups may be tolerated in the alpha-chain. PMID- 27714280 TI - Recent progress towards gold-catalyzed synthesis of N-containing tricyclic compounds based on ynamides. AB - N-Containing tricyclic compounds, especially the tricyclic N-heterocycles, are important structural motifs that possess significant potential in organic chemistry for their momentous applications in natural and man-made bioactive molecules. Gold catalysis, which exhibits specific catalytic properties in terms of both high reactivity and selectivity for various organic transformations, has proven to be a powerful tool for the straightforward synthesis of cyclic compounds, especially the polycyclic molecules. Currently, several approaches towards polycycle synthesis have been developed via gold-catalyzed transformations of readily available ynamides. In this review, we will focus on the recent advances in the gold-catalyzed construction of N-containing tricycles based on ynamides by highlighting their specificity and applicability, and the mechanistic rationale is presented where possible.

AB - An efficient step-economical tandem approach for the direct synthesis of pyrido fused indole, quinoline, benzofuran and benzothiophene derivatives using a bimetallic Pd/Cu catalytic system has been described. The three component reaction of o-halo aldehydes, alkynes and tert-butylamine leads to the synthesis of biologically active polyheterocycles. The present strategy involves the dual role of tert-butylamine and copper(i) in Sonogashira coupling followed by electrophilic cyclization through imine formation. The chemistry has been validated by X-ray crystallographic studies. PMID- 27714282 TI - A fluorescent acrylamide-type monomer bearing an environment-sensitive methoxybenzocoumarin structure for the development of functional polymeric sensors. AB - A new fluorescent acrylamide-type monomer bearing a hydrogen bonding- and polarity-sensitive benzocoumarin fluorophore was synthesized. The absorption spectra, fluorescence spectra, and fluorescence lifetime of a model compound were measured in ten solvents with different hydrogen-bonding abilities and polarities to investigate the sensitivity of the fluorophore to the surrounding environment. These spectroscopic studies demonstrated that the fluorophore emits stronger fluorescence in more protic, polar environments. A fluorescent polymeric thermometer was prepared from N-isopropylacrylamide and the new fluorescent monomer, and it showed good functionality in aqueous solution (e.g., high sensitivity to temperature changes and high chemical stability), indicating the applicability of the herein developed fluorescent monomer for use in functional sensors. PMID- 27714283 TI - Synthesis and biological evaluation of triazole based uracil derivatives as novel DPP-4 inhibitors. AB - A series of triazole based uracil derivatives were designed and synthesized as novel DPP-4 inhibitors. Compound A01 was identified as a lead compound for SAR studies focused on the structural modification at the S2' subsite of DPP-4. The novel analogues A02-A25 were obtained by modifying the substituents at the phenyl group, and B01-B09, by introducing the carbonyl group. On screening in DPP-4, compounds B03, B04 and B08 showed a significant improvement in DPP-4 inhibitory activities compared to compound A01 and showed comparable activities to the marketed DPP-4 inhibitor, alogliptin. Docking studies revealed new favorable binding modes of designed compounds in the S2' subsite and proved that structural modifications in the S2' subsite were an effective option to increase the inhibition of DPP-4. In vitro DPP-8 and DPP-9 tests indicated that all compounds showed excellent selectivity against DPP-8 and DPP-9. Further in vivo evaluation showed that compound B04 could significantly improve oral glucose tolerance in ICR mice and dose-dependently reduced glucose levels in type 2 diabetic C57BL/6 mice. These data suggest that compound B04 could be a promising DPP-4 inhibitor for future treatment of T2DM.

AB - I2-Mediated benzyl C-H functionalization has been developed for the synthesis of 2H-indazoles, which features high efficiency, simple conditions and no need for metals. Mechanistic experiments and DFT calculations have revealed halogen bond assistance and a radical chain process for this reaction. The azo group and the bound iodine cooperate in the hydrogen abstraction step, which circumvents the thermodynamic disfavor of direct hydrogen abstraction by a simple iodine radical. PMID- 27714285 TI - Regioselective synthesis of functionalized dihydroisoquinolines from o alkynylarylaldimines via the Reformatsky reaction. AB - A novel approach for the synthesis of functionalized 1,2-dihydroisoquinolines from o-alkynylarylaldimines via the Reformatsky reaction without the aid of an external Lewis acid has been described. The chemistry involves the dual role of the Reformatsky reagent which has been generated in situ in the reaction. We propose that one molecule of the Reformatsky reagent is being utilised for the activation of alkynes, whereas the second molecule acts as a nucleophile on the iminium carbon. This synthetic pathway has high functional group tolerance, and can be utilized on a gram scale. The proposed mechanistic pathway is well supported by the control experiments. The 1,2-dihydroisoquinoline derivatives showed up to 90% inhibition of the strand transfer activity of the HIV integrase enzyme. PMID- 27714286 TI - Generalized drift velocity of a cholesteric texture in a temperature gradient. AB - We propose a general method to calculate the drift velocity of cholesteric textures subjected to a temperature gradient when the backflow effects are negligible. The textures may be Translationally Invariant Configurations (TICs) or localized structures such as cholesteric droplets or cholesteric fingers. For the TICs and for the droplets, the drift is rotational while for the fingers, the drift is translational. We show that for the TICs, the drift is only due to the thermomechanical coupling terms of Leslie (classical term) and of Akopyan and Zel'dovich (which are additional texture-dependent terms). For the localized structures, we show that another mechanism involving the temperature variations of the elastic constants and the existence of a transverse temperature gradient can lead to a drift which adds to the one due the classical thermomechanical effects.

AB - Visible light active photocatalysts consisting of gold nanoparticle (Au NP) decorated chemically reduced graphene oxide-P25 nanocomposite materials (CRGO-P25 Au NCMs) were prepared through a one-pot chemical reduction method. The nanocomposite materials were characterized using diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM) and electrochemical impedance spectroscopy (EIS) analyses. The performances of CRGO-P25-Au NCM modified ITO electrodes were evaluated towards the photoelectrochemical oxidation of methanol. The photoelectrode fabricated using CRGO-P25-Au NCM exhibited a higher photocurrent of 293 MUA cm-2 compared to other control electrodes. The CRGO-P25-Au NCMs were also used for the photocatalytic reduction of highly toxic chromium(vi) ions to chromium(iii) ions in the presence of oxalic acid as a sacrificial electron donor. The results showed that around 75% of the Cr(vi) ions were photocatalytically reduced to Cr(iii) ions by the CRGO-P25-Au NCM within the light irradiation time of 1 h. In both applications, the enhanced catalytic activity of the CRGO-P25-Au NCM was attributed to the improved visible light absorption and the reduced charge recombination exerted by the interaction of CRGO and Au NPs with P25 and their synergistic effects.

AB - A unified, asymmetric approach to the total synthesis of naturally occurring iridoids is presented. The synthesis features a recently discovered ortho -> alpha transmetalation of alkyl aryl sulfone carbanions, thus enabling Julia reactions, by which so far hardly accessible disilylated olefins have been obtained. A subsequent tandem alkoxycarbonylation/oxidative radical cyclization afforded substituted cyclopentane building blocks with high diastereoselectivity. These compounds serve as unique central intermediates for short access to dihydronepetalactone, dolicholactone and potentially other iridoids.

AB - We report regioselective N(1)-arylation of protected histidine using copper(i) iodide as a catalyst, trans-N,N'-dimethylcyclohexane-1,2-diamine as a ligand and readily available aryl iodides as coupling partners under microwave irradiation at 130 degrees C for 40 min. The reaction provides rapid access to electron donating, electron-withdrawing and bulky group substituted N-arylated histidines in high yields, including previously inaccessible N-heteroaryl histidines. These N(1)-(hetero)aryl histidines are promising building blocks in peptide-based drug design and discovery.

AB - The reaction of amines with pentafluorophenyl-substituted A3B-porphyrins has been used to obtain different useful reactive groups for further functionalization and/or conjugation of these porphyrins to other substrates or materials. Porphyrins with alkenyl, alkynyl, amino, azido, epoxide, hydroxyl, and maleimido groups have thus been synthesized. For the first time such functionalized porphyrins have been conjugated to hyperbranched polyglycerol (hPG) as a biocompatible carrier system for photodynamic therapy (PDT) using the copper(i) catalyzed 1,3-dipolar cycloaddition (CuAAC). The photocytotoxicity of selected porphyrins as well as of the porphyrin-hPG-conjugates has been assessed in cellular assays with human epidermoid carcinoma A-253 and squamous carcinoma CAL 27 cells. For several biomedical applications a release of the active drug and/or fluorescent dye is desired. Therefore, additionally, the synthesis of A3B porphyrins with cleavable linker moieties is presented, namely disulfide, cleavable in a reductive environment, and acetal linkers whose cleavage is pH triggered.

AB - The microphase separation behavior of block copolymers confined in cylindrical nanopores has been extensively investigated. Recently, the solvent-annealing induced nanowetting in templates (SAINT) method has been demonstrated to be a versatile approach for the infiltration of block copolymers into the nanopores of porous templates. The function of the annealing solvents, however, is still not well understood, especially in the morphology control of the fabricated block copolymer nanostructures. In this work, we elucidate the function of the annealing solvents in the SAINT method using a lamella-forming block copolymer, polystyrene-block-polydimethylsiloxane (PS-b-PDMS), and anodic aluminum oxide (AAO) templates. By changing the composition of the annealing solvents, different morphologies such as the concentric lamellar morphology, the winding cylinder morphology, and the irregular hybrid morphology are observed, mainly caused by the annealing-solvent-induced volume change. The morphology of the block copolymer nanostructures can be further confirmed using an HF solution to remove the PDMS domain selectively. PMID- 27714292 TI - Torsional stiffness determines aggregate structure in sheared colloidal rod suspensions. AB - We report the results of simulations of suspensions of sheared rigid rods in the presence of strong attractive inter-particle interactions, using dissipative particle dynamics for a coarse-grained representation of the suspending fluid. We find that the combined effect of the attractive interactions and shear-induced alignment generically produces aggregates of aligned bundles when the contact points between rods are free to rotate. However, the introduction of substantial torsional stiffness to the inter-particle contacts recapitulates the disordered aggregates often observed in suspensions of high aspect ratio particles. We show that the degree of alignment within the aggregates depends on the strength of the torsional stiffness, while the stability of the aggregates and their impact on system viscosity depend on the competition between the attractive interaction and the shear stresses. PMID- 27714293 TI - Enhancing and reducing chirality by opposite circularly-polarized light irradiation on crystalline chiral domains consisting of nonchiral photoresponsive W-shaped liquid crystal molecules. AB - We found possible chirality enhancement and reduction in chiral domains formed by photoresponsive W-shaped molecules by irradiation with circularly polarized light (CPL). The W-shaped molecules exhibit a unique smectic phase with spontaneously segregated chiral domains, although the molecules are nonchiral. The chirality control was generated in the crystalline phase, which shows chiral segregation as in the upper smectic phase, and the result appeared to be as follows: for a certain chiral domain, right-CPL stimuli enhanced the chirality, while left-CPL stimuli reduced the chirality, and vice versa for another chiral domain. Interestingly, no domain-size change could be observed after CPL irradiation, suggesting some changes in the causes of chirality. In this way, the present system can recognize the handedness of the applied chiral stimuli. In other words, the present material can be used as a sensitive chiral-stimuli-recognizing material and should find invaluable applications, including in chiroptical switches, sensors, and memories as well as in chiral recognition. PMID- 27714294 TI - Stretching liquid bridges with moving contact lines: comparison of liquid transfer predictions and experiments. AB - Transfer of liquid from one surface to another plays a key role in printing processes. During liquid transfer, a liquid bridge is formed and then undergoes significant extensional motion while its contact lines are free to move on the bounding solid surfaces. In this work, we develop one-dimensional (1D) slender jet and two-dimensional (2D) axisymmetric models of this phenomenon and compare the resulting predictions with previously published experimental data. For very low capillary numbers (Ca) (quasi-static stretching), predictions from both models of the amount of liquid transferred agree well with the experimental data, provided that the difference in receding contact angles (|Deltathetar|) between the two surfaces is sufficiently large. Notably, the amount of liquid transferred is primarily governed by the overall bridge shape and is not significantly influenced by contact-line motion toward the end of bridge stretching. For O(1) values of Ca, the models predict that each surface receives half the liquid, in agreement with experimental observations. For intermediate values of Ca (and very low values of Ca when |Deltathetar| is small enough), predictions from each model can deviate substantially from the experimental data, which we speculate is due to the influence of surface heterogeneities that are not included in the models. In this regime, there can be significant differences between the predictions of the 1D and 2D models, which is due to the tendency of the contact line to slip more in the 1D model. The models are also used to understand the influence of initial bridge shape on liquid transfer and to rationalize related experimental observations. The results from these fundamental studies will aid the optimization of gravure and other printing processes for manufacturing of printed electronic devices.

The key steps involve a stereoselective Lewis acid promoted C glycosylation of protected phloroglucinol with tetrabenzylglucopyranosyl acetate and a highly regioselective base-induced cyclization for the construction of the core xanthone skeleton. PMID- 27714297 TI - Structure-activity studies of non-steroid analogues structurally-related to neuroprotective estrogens. AB - Estrone and 17beta-estradiol are phenolic steroids that are known to be neuroprotective in multiple models of neuronal injury. Previous studies have identified the importance of their phenolic steroid A-ring for neuroprotection and have identified ortho substituents at the C-2 and C-4 positions on the phenol ring that enhance this activity. To investigate the importance of the steroid ring system for neuroprotective activity, phenolic compounds having the cyclopent[b]anthracene, cyclopenta[b]phenanthrene, benz[f]indene, benz[e]indene, indenes linked to a phenol, and a phenolic spiro ring system were prepared. New synthetic methods were developed to make some of the cyclopent[b]anthracene analogues as well as the spiro ring system. Compounds were evaluated for their ability to protect HT-22 hippocampal neurons from glutamate neurotoxicity and their activity relative to a potent neuroprotective analogue of 17beta-estradiol was determined. An adamantyl substituent placed ortho to the phenolic hydroxyl group gave neuroprotective analogues in all ring systems studied. PMID- 27714298 TI - Co-assembly of polyoxometalates and peptides towards biological applications. AB - The synergistic self-assembly of biomolecules with polyoxometalates (POMs) has recently been considered as an effective approach to construct nano-biomaterials with diverse structures and morphologies towards applications in drug delivery, controlled release, tissue engineering scaffolds, and biomineralization, due to the unique features of the clusters in addition to many well-known inorganic nanoparticles. This review presents an overview of recent work focusing on the noncovalent co-assembly of peptides and POMs as well as their biological applications. In the co-assemblies triggered by the interaction between the components significant advantages are observed that POMs or peptides alone do not possess; examples include chiral recognition of hybrid metal oxides, the quick hydrolysis of peptides, and enhanced inhibition of Abeta aggregation. Finally, we outline a brief perspective on possible unresolved issues and future opportunities in this field. PMID- 27714299 TI - Characterisation of 6-DMATSMo from Micromonospora olivasterospora leading to identification of the divergence in enantioselectivity, regioselectivity and multiple prenylation of tryptophan prenyltransferases. AB - Prenylated secondary metabolites including indole derivatives usually demonstrate improved biological and pharmacological activities, which make them promising candidates for drug discovery and development. The transfer reactions of a prenyl moiety from a prenyl donor, e.g. dimethylallyl diphosphate (DMAPP), to an acceptor is catalysed by prenyltransferases. One special group of such enzymes uses DMAPP and tryptophan as substrates with dimethylallyltryptophans as reaction products and functions therefore as dimethylallyltryptophan synthases (DMATSs). Sequence homology search with known tryptophan prenyltransferases from Streptomyces led to identification of a putative prenyltransferase gene MolI14.36 in Micromonospora olivasterospora. Expression and biochemical investigations revealed that MolI14.36 acts as a tryptophan C6-prenyltransferase (6-DMATSMo). Study on substrate specificity of 6-DMATSMo displayed a significantly high activity towards d-tryptophan, which prompted us to carry out comparative studies on enantioselectivity, regioselectivity and multiple prenylation ability of additional DMATSs including FgaPT2, 5-DMATS, 5-DMATSSc, 6-DMATSSv, 6-DMATSSa and 7-DMATS towards l- and d-isomers of tryptophan and their analogues. The relative activities of the tested enzymes towards d-tryptophan differ clearly from each other. Incubation of l-, d-isomers or the racemates of 5-, 6- and 7 methyltryptophan revealed distinctly different preferences of the DMATS enzymes. Interestingly, 6-DMATSMo and 5-DMATSSc accepted 5-methyl-d-tryptophan much better than the l-enantiomer. Furthermore, the conversion yields of the d-isomers were strongly inhibited in the reactions with racemates. More interestingly, the regioselectivities of FgaPT2, 5-DMATSSc and 7-DMATS towards d-tryptophan and its C5-methylated derivative differed clearly from those of the l-forms. In addition, both mono- and diprenylated products were clearly detected for 5-DMATSSc with l- and d-enantiomers of tryptophan and their methylated derivatives. PMID- 27714300 TI - 4,4'-Bismoschamine: biomimetic synthesis and evidence to support structural equivalency to montamine. AB - The dimeric natural product montamine was originally reported as two N feruloylserotonin (moschamine) units linked by a nitrogen-nitrogen bond, but our recent synthesis of this symmetrical diacyl hydrazide structure revealed this to be incorrect. We subsequently hypothesized that the moschamine subunits were linked through the indole C4 site and that montamine was structurally identical to 4,4'-bismoschamine, a known natural product present in safflower oil. However, given that authentic samples of both montamine and 4,4'-bismoschamine were unavailable and that the NMR data for the natural products were recorded in different solvents, we were unable to unequivocally prove this hypothesis. A recent publication that claims montamine and 4,4'-bismoschamine are not the same natural product prompts us to disclose our own findings on this matter. A biomimetic synthesis of 4,4'-bismoschamine was developed that hinged on oxidative coupling of N-Boc-serotonin followed by elaboration of the resulting 4,4'-dimer to the natural product. A detailed comparison of the NMR data for synthetic 4,4' bismoschamine with that reported for montamine revealed that while the 1H NMR data were in good agreement, the 13C NMR data displayed some discrepancies. In light of this result, the NMR data for several literature compounds was analyzed, the results of which revealed that the upfield chemical shifts of the methylene protons in the 1H NMR of montamine is unique to 4,4'-bistryptamines, supporting our initial statement that montamine and 4,4'-bismoschamine are structurally equivalent. Given that the main differences in the 13C NMR data between montamine and synthetic 4,4'-bismoschamine occur at the quaternary carbons, we propose that these peaks have been misassigned from a 13C NMR spectrum that was obtained from an impure sample and/or the small amount of montamine (4 mg) isolated from the natural source.

AB - We have measured the creep response of soft gels and cells after applying a step in loading force with atomic force microscopy (AFM). By analysing the creep response data using the standard linear solid model, we can quantify the viscous and elastic properties of these soft samples independently. Cells, in comparison with gels of similar softness, are much more viscous, as has been qualitatively observed in conventional force curve data before. Here, we quantify the spring constant and the viscous damping coefficient from the creep response data. We propose two different modes for applying a force step: (1) indirectly by increasing the sample height or (2) directly by employing magnetic cantilevers. Both lead to similar results, whereas the latter seems to be better defined since it resembles closely a constant strain mode. The former is easier to implement in most instruments, and thus may be preferable from a practical point of view. Creep analysis by step response is much more appropriate to analyse the viscoelastic response of soft samples like cells than the usually used force curve analysis.

AB - Optimal immobilization of enzymes on porous microbeads enables the fabrication of highly active and stable heterogeneous biocatalysts to implement biocatalysis in synthetic and analytical chemistry. However, empirical procedures for enzyme immobilization still prevail over rational ones because there is an unmet need for more comprehensive characterization techniques that aid to understand and trace the immobilization process. Here, we present the use of atomic force spectroscopy (AFS) as an innovative solution to indirectly characterize immobilized proteins on porous materials and monitor the immobilization process in real time. We investigate the mechanical properties of porous agarose microbeads immobilizing proteins by indenting a colloidal probe (silica microparticle) into a single bead. AFS demonstrates that the binding of proteins to the solid matrix of an agarose microbead alters its stiffness. Interestingly, we discovered that irreversible and multivalent immobilizations that make microbeads stiffer also stabilize the immobilized proteins against the temperature. Hence, we propose atomic force spectroscopy as a useful technique to indirectly unravel the stability of the immobilized enzymes investigating the mechanics of the heterogenous biocatalysts as a solid biomaterial beyond the intrinsic mechanics of the proteins.

The oxocene ring of the target compound is formed via ring-closing metathesis, a process that depends on certain structural requirements.

This synthetic strategy is also applicable to the synthesis of other oxocene terpenes. PMID- 27714306 TI - Collective ratchet effects and reversals for active matter particles on quasi-one dimensional asymmetric substrates. AB - Using computer simulations, we study a two-dimensional system of sterically interacting self-mobile run-and-tumble disk-shaped particles with an underlying periodic quasi-one-dimensional asymmetric substrate, and show that a rich variety of collective active ratchet behaviors arise as a function of particle density, activity, substrate period, and the maximum force exerted by the substrate. The net dc drift, or ratchet transport flux, is nonmonotonic since it increases with increased activity but is diminished by the onset of self-clustering of the active particles. Increasing the particle density decreases the ratchet transport flux for shallow substrates but increases the ratchet transport flux for deep substrates due to collective hopping events. At the highest particle densities, the ratchet motion is destroyed by a self-jamming effect. We show that it is possible to realize reversals of the direction of the net dc drift in the deep substrate limit when multiple rows of active particles can be confined in each substrate minimum, permitting emergent particle-like excitations to appear that experience an inverted effective substrate potential. We map out a phase diagram of the forward and reverse ratchet effects as a function of the particle density, activity, and substrate properties.

AB - We investigate polymer diffusion in a quasi-two-dimensional environment decorated with attractive cylindrical posts using Langevin dynamics simulation. We find that the polymer diffusivity has non-monotonic dependence on the post array density. This diffusive behavior strongly depends on the adsorption-desorption transition and the critical adsorption strength epsilonc. For epsilon < epsilonc, the polymer undergoes normal diffusion and the diffusivity decreases as the post density increases due to the reduction of the void volume. For epsilon > epsilonc, polymer dynamics is strongly mediated by post adsorption, and we observe a regime where the polymer diffusivity increases as the post density increases. The polymer diffusivity reaches a maximum, which can be attributed to cross-post translation enabled by large polymer conformation fluctuations. We find both cross-post transport and polymer conformation fluctuations strongly depend on the post absorption strength and the chain length. PMID- 27714309 TI - The self-assembly structure and the CO2-philicity of a hybrid surfactant in supercritical CO2: effects of hydrocarbon chain length. AB - Hybrid surfactants containing both fluorocarbon (FC) and hydrocarbon (HC) chains, as effective CO2-philic surfactants, could improve the solubility of polar substances in supercritical CO2. Varying the length of the HC of hybrid surfactants is an effective way to improve the CO2-philicity. In this paper, we have investigated the effects of the HC length on the self-assembly process and the CO2-philicity of hybrid surfactants (F7Hn, n = 1, 4, 7 and 10) in water/CO2 mixtures using molecular dynamics simulations. It is found that the self-assembly time of F7Hn exhibits a maximum when the length of the HC is equal to that of the FC (F7H7). In this case, the investigation of H-bonds between the water core and CO2 phase shows that F7H7 has the strongest CO2-philicity because it has the best ability to separate water and CO2. To explain the origin of the differences in separation ability, the analysis of the structures of the reverse micelles shows that there are two competing mechanisms with a shortening HC. Firstly, the volume of F7Hn is reduced, which thus decreases the separation ability. Moreover, this also leads to the curved conformation of the FC. As a result, the separation ability is enhanced. These two mechanisms are balanced in F7H7, which has the best ability to separate water and CO2. Our simulation results demonstrate that the increased volume and the curved conformation of the hybrid surfactant tail could enhance the CO2-philicity in F7Hn surfactants. It is expected that this work will provide valuable information for the design of CO2-philic surfactants. PMID- 27714310 TI - Nile red fluorescence for quantitative monitoring of micropolarity and microviscosity of pluronic F127 in aqueous media. AB - The photophysical behaviour and excited state decay kinetics of the fluorescent probe Nile red were used for quantitative monitoring of micropolarity, microviscosity and the sol-gel transition temperature of a copolymer hydrogel, pluronic F127. There was considerable enhancement of the emission intensity with a large blue shift in emission and an absorption maximum at and above the sol-gel transition temperature (20 degrees C), showing the sensitivity of Nile red fluorescence to the sol-gel transition. The estimation of micropolarity by comparing the Nile red emission maximum in dioxane-water mixtures suggested a considerable decrease in the polarity of the PF127 microenvironment from less polar (20% dioxane-water) in its sol phase to almost non-polar (90% dioxane water) microenvironments in the gel phase. The thermotropic response of the wavelength dependent fluorescence lifetime of the probe with a rise time in the longer wavelength region has enabled monitoring of the microheterogeneity of the gel medium. With an increase in temperature, the microviscosity progressively increases from ~10 mPa s (sol state) to ~23 mPa s (gel state). The mismatch between microviscosity as estimated by the Nile red and the corresponding bulk viscosity reflected the microheterogeneity of the pluronic medium and its sensitivity towards PF127 microenvironments.

AB - Photodynamic therapy (PDT) is a promising antineoplastic modality in the oncology field. We assessed the safety of repeated intravenous administrations of sinoporphyrin, a porphyrin derivative, with and without illumination in rats. Toxicokinetic studies of single and multiple administrations of sinoporphyrin were also carried out. Sprague-Dawley rats were randomly assigned to the dark toxicity and PDT groups. Animals in the dark toxicity group received an i.v. infusion of sinoporphyrin at 3 doses: 2 mg kg-1, 6 mg kg-1, and 18 mg kg-1. The PDT group included 2 doses of sinoporphyrin (2 mg kg-1 and 18 mg kg-1), and the rats received 60 J of 630 nm laser illumination 24 h after photosensitizer infusion. The treatments were repeated every 7 days for 5 cycles and were followed by a 14-day recovery period. Systematic analyses were conducted at the end of treatment and recovery periods. Blood samples were obtained 5 min, 30 min, 2 h, 8 h, 24 h, 48 h, 72 h, and 96 h after the first and fifth treatments for toxicokinetic studies. Sinoporphyrin-PDT led to the death of one out of 270 rats; the dead animal had been treated with 18 mg kg-1 sinoporphyrin and died at the end of the fifth PDT treatment. Liver injury, the primary toxicity observed in the study, was identified using biochemical tests, necropsy, and histopathology. Elevated white blood cell and neutrophil counts were found in the rats in both the dark toxicity and PDT groups. Skin lesions at the illumination site were obvious in the PDT group. Pigment deposits were detected in multiple organs such as the liver, spleen, lymph nodes, and ovaries in the 6 mg kg-1 and 18 mg kg-1 groups. No other abnormalities were observed. The toxicokinetic parameters of single and multiple sinoporphyrin administrations were calculated and compared. Repeated sinoporphyrin administrations both alone and in combination with laser illumination were tolerable, and all toxicities were transient. The no observed adverse effect level (NOAEL) for repeated sinoporphyrin administration and sinoporphyrin-PDT was 6 mg kg-1 and 2 mg kg-1, respectively. Further studies are warranted. PMID- 27714313 TI - The role of UVR and vitamin D on T cells and inflammatory bowel disease. AB - Vitamin D deficiency is associated with the development of inflammatory bowel disease (IBD). In experimental IBD the targets of vitamin D that result in protection from IBD include gut epithelial cells, innate immune cells, T cells, and the microbiota. Ultraviolet radiation (UVR) induces production of vitamin D in the skin and suppresses T cell responses in the host. There is limited data demonstrating an effect of UVR on experimental IBD but the mechanisms of UVR suppression in IBD have not been defined. There are several shared effects of vitamin D and UVR on T cells including inhibition of proliferation and suppression of IFN-gamma and IL-17 producing T cells. Conversely UVR decreases and vitamin D increases IL-4 production from T cells. Together the data suggest that UVR suppression of T cells and potentially IBD are both vitamin D dependent and independent.

AB - This study aimed at investigating the photocatalytic degradation of humic acid (HA) as a representative of natural organic matter (NOM) by using Ce-doped ZnO as a novel material. Following photocatalysis, HA degradation was characterized by specified UV-vis and fluorescence spectroscopic parameters as well as by the dissolved organic carbon (NPOC) content. Excitation-Emission Matrix (EEM) fluorescence features were also evaluated by using advanced techniques. Comparison of Ce-doped ZnO photocatalysis to TiO2 P-25 photocatalytic treatment of the HA samples was elucidated under similar experimental conditions. Kinetic modeling of the photocatalytic removal of HA expressed promising results indicating that Ce-doped ZnO could serve as an efficient catalyst for the degradation of NOM. PMID- 27714315 TI - Shear dynamics of an inverted nematic emulsion. AB - Here we study theoretically the dynamics of a 2D and a 3D isotropic droplet in a nematic liquid crystal under a shear flow. We find a large repertoire of possible nonequilibrium steady states as a function of the shear rate and of the anchoring of the nematic director field at the droplet surface. We first discuss homeotropic anchoring. For weak anchoring, we recover the typical behaviour of a sheared isotropic droplet in a binary fluid, which rotates, stretches and can be broken by the applied flow. For intermediate anchoring, new possibilities arise due to elastic effects in the nematic fluid. We find that in this regime the 2D droplet can tilt and move in the flow, or tumble incessantly at the centre of the channel. For sufficiently strong anchoring, finally, one or both of the topological defects which form close to the surface of the isotropic droplet in equilibrium detach from it and get dragged deep into the nematic state by the flow. In 3D, instead, the Saturn ring associated with the normal anchoring disclination line can be deformed and shifted downstream by the flow, but remains always localized in the proximity of the droplet, at least for the parameter range we explored. Tangential anchoring in 2D leads to a different dynamic response, as the boojum defects characteristic of this situation can unbind from the droplet under a weaker shear with respect to the normal anchoring case. Our results should stimulate further experiments with inverted liquid crystal emulsions under shear, as most of the predictions can be testable in principle by monitoring the evolution of liquid crystalline orientation patterns or by tracking the position and shape of the droplet over time.

Studies on its conformation in solution are critical for understanding its catalytic mechanism and functional optimization. Based on our previous research, two fluorescent nucleoside analogues 1 and 2 were designed for the introduction of a pyrenyl group at one of the five dA residues in the catalytic core and the unpaired adenosine residue in its full-DNA substrate, respectively. Ten pyrenyl-pyrenyl pairs are formed in the DNAzyme-substrate complexes in solution for sensing the spacial positions of the five dA residues relative to the cleavage site using fluorescence spectra. The position-dependent quenching effect of pyrene emission fluorescence by nucleobases, especially the pyrenyl-pyrenyl interaction, was observed for some positions. The adenine residues in the 3'-part of the catalytic loop seem to be closer to the cleavage site than the adenine residues in the 5'-part, which is consistent with the molecular dynamics simulation result. The catalytic activities and Tm changes also confirmed the effect of the pyrenyl-nucleobase and pyrenyl-pyrenyl pair interactions. Together with functional group mutations, catalytically relevant nucleobases will be identified for understanding the catalytic mechanism of 10-23 DNAzyme.

When frictional damping dominates over viscous dissipation, we eliminate flow in favor of active stresses to obtain a minimal dynamical model for the nematic order parameter, with elastic constants renormalized by activity. The renormalized elastic constants can become negative at large activity, leading to the selection of spatially inhomogeneous patterns via a mechanism analogous to that responsible for modulated phases arising at an equilibrium Lifshitz point. Tuning activity and the degree of nematic order in the passive system, we obtain a linear stability phase diagram that exhibits a nonequilibrium tricritical point where ordered, modulated and disordered phases meet. Numerical solution of the nonlinear equations yields a succession of spatial structures of increasing complexity with increasing activity, including kink walls and active turbulence, as observed in experiments on microtubule bundles confined at an oil-water interface. Our work provides a minimal model for an overdamped active nematic that reproduces all the nonequilibrium structures seen in simulations of the full active nematic hydrodynamics and provides a framework for understanding some of the mechanisms for selection of the nonequilibrium patterns in the language of equilibrium critical phenomena.

AB - We report a comparative X-ray diffraction study on three series of comb-like polymers with rigid backbones and layered morphologies [regio-regular poly(3 alkyl thiophenes), alkoxylated polyesters, alkoxylated polyphenylenevinylenes] highlighting the importance of the volume per methylene unit VCH2 in alkyl nanodomains for the overall packing state. We demonstrate that there is a large (~30%) variation in the VCH2 values for different polymer series and packing states but no significant change in VCH2 depending on the length of the alkyl side groups. This calls into question commonly used structural models which are based only on tilting and interdigitation of ideally stretched alkyl side groups. We argue that a linear dependence of the layer spacings with side chain length can also be explained by a constant VCH2 value and unchanged main chain packing. The potential importance of side chain packing for the occurrence of different (liquid-) crystalline modifications in various polymer series and possible interrelations between main and side chain packings are discussed.

AB - Modified Pt-TiO2 NPs/decorated carbon nanotubes were synthesized utilizing sonochemical/hydration-dehydration techniques. Pt was loaded on TiO2 by a photodeposition method keeping in mind the end goal to achieve electron-hole pair separation and promote the surface reaction. The morphological and basic properties of Pt-TiO2/fCNTs were investigated by field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM), powder X-ray diffraction (XRD), UV-vis diffuse reflectance spectroscopy (DRS), photoluminescence (PL) and Raman spectroscopy. The selected area electron diffraction (SAED) patterns of Pt-TiO2/fCNTs were obtained utilizing TEM-based energy dispersive X-ray spectroscopy (EDXS) analysis. It was found that the TiO2 nanoparticles were uniformly distributed on the fCNTs, and the Pt particles were decorated on the surface of TiO2/fCNTs. The photocatalytic hydrogen production activity of the Pt(0.5%)-TiO2/fCNTs(0.5%) nanoparticle composites was investigated using a sacrificial agent methanol solution. Pt-loaded TiO2 demonstrated a hydrogen evolution rate around 20 times that of TiO2/fCNTs(0.5%) (fSWCNTs, fMWCNTs). When compared with platinized TiO2 in methanol, which was utilized as a control material, Pt-TiO2/fCNTs demonstrated an almost 2-fold increment in hydrogen generation.

AB - A Prussian blue/carbon dot (PB/CD) nanocomposite was synthesised and used as a visible-light active photocatalyst for the oxidative cyanation of tertiary amines to alpha-aminonitriles by using NaCN/acetic acid as a cyanide source and H2O2 as an oxidant. The developed photocatalyst afforded high yields of products after 8 h of visible light irradiation at room temperature. The catalyst was recycled and reused several times without any significant loss in its activity. PMID- 27714322 TI - Spectroscopic studies of the interaction of 3-(2-thienyl)-[1,2,3]triazolo[1,5 a]pyridine with 2,6-dimethyl-beta-cyclodextrin and ctDNA. AB - The inclusion complexation behavior of 3-(2-thienyl)-[1,2,3]triazolo[1,5-a] pyridine (TTP) with native beta-cyclodextrin and derivatized cyclodextrins was investigated. Stability constants for complexes with 1 : 1 molar ratios were calculated from phase solubility diagrams. The solubilizing efficiency of the TTP inclusion complex is enhanced in the order of DMbetaCD > HPbetaCD > betaCD. The TTP-DMbetaCD inclusion complex was further characterized in solution by means of absorption, fluorescence, 2D NMR and molecular modeling methods. The thermodynamic studies indicate that the inclusion of TTP into the cyclodextrin cavity is mainly an enthalpy-driven process. The 2D NMR studies revealed that the thienyl moiety of TTP is inserted into the CD cavity while the triazolopyridine protrudes the primary rim of the DMbetaCD, which are in good agreement with docking results. The fluorescence titration of TTP by ctDNA suggested that the quenching mechanism is a dynamic quenching procedure resulting from the temperature dependence of the TTP-ctDNA complex. Thermodynamics of the interaction revealed that the positive values of DeltaH and DeltaS announced that the binding process was primarily driven by hydrophobic forces indicating that TTP interacts with ctDNA by means of the minor groove. These results are in good agreement with docking experiments and iodide experiments which reinforce TTP's interactions in the minor groove. PMID- 27714323 TI - Mesoporous self-assembled nanoparticles of biotransesterified cyclodextrins and nonlamellar lipids as carriers of water-insoluble substances. AB - Soft mesoporous hierarchically structured particles were created by the self assembly of an amphiphilic deep cavitand cyclodextrin betaCD-nC10 (degree of substitution n = 7.3), with a nanocavity grafted by multiple alkyl (C10) chains on the secondary face of the betaCD macrocycle through enzymatic biotransesterification, and the nonlamellar lipid monoolein (MO). The effect of the non-ionic dispersing agent polysorbate 80 (P80) on the liquid crystalline organization of the nanocarriers and their stability was studied in the context of vesicle-to-cubosome transition. The coexistence of small vesicular and nanosponge membrane objects with bigger nanoparticles with inner multicompartment cubic lattice structures was established as a typical feature of the employed dispersion process. The cryogenic transmission electron microscopy (cryo-TEM) images and small-angle X-ray scattering (SAXS) structural analyses revealed the dependence of the internal organization of the self-assembled nanoparticles on the presence of embedded betaCD-nC10 deep cavitands in the lipid bilayers. The obtained results indicated that the incorporated amphiphilic betaCD-nC10 building blocks stabilize the cubic lattice packing in the lipid membrane particles, which displayed structural features beyond the traditional CD nanosponges. UV-Vis spectroscopy was employed to characterize the nanoencapsulation of a model hydrophobic dimethylphenylazo-naphthol guest compound (Oil red) in the created nanocarriers. In perspective, these dual porosity carriers should be suitable for co-encapsulation and sustained delivery of peptide, protein or siRNA biopharmaceuticals together with small molecular weight drug compounds or imaging agents.

AB - Liquid foams are excellent systems to mitigate pressure waves such as acoustic or blast waves. The understanding of the underlying dissipation mechanisms however still remains an active matter of debate. In this paper, we investigate the attenuation of a weak blast wave by a liquid foam. The wave is produced with a shock tube and impacts a foam, with a cylindrical geometry. We measure the wave attenuation and velocity in the foam as a function of bubble size, liquid fraction, and the nature of the gas. We show that the attenuation depends on the nature of the gas and we experimentally evidence a maximum of dissipation for a given bubble size. All features are qualitatively captured by a model based on thermal dissipation in the gas. PMID- 27714325 TI - Light harvesting a gold porphyrin-zinc phthalocyanine supramolecular donor acceptor dyad. AB - We reported herein the spectroscopic, electrochemical and laser photolysis studies for the newly constructed light harvesting supramolecular dyad composed of gold porphyrin (AuPpy), as an electron acceptor, and zinc phthalocyanine (ZnPc), as an electron donor, to mimic the reaction centre in the photosynthetic system. For this, gold porphyrin has been functionalized by pyridine units, which axially coordinated with zinc phthalocyanine to form the stable supramolecular AuPpy:ZnPc with a rate of 2.94 * 104 M-1. Steady-state fluorescence measurements showed significant quenching of the singlet excited ZnPc emission with addition of AuPpy, suggesting an electron transfer from the singlet excited ZnPc to AuPpy. The electron transfer character was confirmed by recoding the characteristic absorption band of the zinc phthalocyanine radical cation in the NIR region by a femtosecond laser photolysis technique. The findings that the AuPpy:ZnPc supramolecular dyad exhibits relatively long-lived radical-ion pairs and absorbs light in a wide range of the solar spectrum suggest that it would be useful as a photosynthetic reaction centre. PMID- 27714326 TI - Formation of simple single-tailed vesicles mediated by lipophilic solid surfaces. AB - Adsorption and aggregation of surfactants at solid-liquid interfaces were fairly well understood, but there was limited knowledge regarding the effect of the presence of a solid surface on aggregate structures in bulk solution. Except for the fatty acid system, most simple single-tailed surfactants (STSs) are well known to form micelles but not vesicles in aqueous solution. Herein, we report a novel phenomenon: with the mediation of lipophilic solid surfaces (LSSs), the zwitterionic STS lauryl sulfobetaine (LSB) formed vesicles from its micellar solution without any additives, producing a mixed solution of vesicles and micelles. More interestingly, the STS vesicles coexisted stably with micelles in the solution and were thermally insensitive even after the removal of LSSs. The quantity of LSB vesicles decreases with the addition of ethanol. The pH effects (4.0-9.0) did not have an obvious influence on the formation and stability of the LSB vesicles. Similar results were obtained from the other STSs, suggesting that the LSS-mediated micelle-to-vesicle transition may be a general phenomenon. We proposed a possible mechanism that adsorption, the matrix effect, and interdigitated bilayer structures were probably crucial for the formation and stability of STS vesicles. We expect this work to provide important insights into the effect of the solid/liquid interface on the self-assembly chemistry of surfactants in bulk solution. PMID- 27714327 TI - Computational insight into the cooperative role of non-covalent interactions in the aza-Henry reaction catalyzed by quinine derivatives: mechanism and enantioselectivity. AB - Density functional theory (DFT) calculations were performed to elucidate the mechanism and the origin of the high enantioselectivity of the aza-Henry reaction of isatin-derived N-Boc ketimine catalyzed by a quinine-derived catalyst (QN). The C-C bond formation step is found to be both the rate-determining and the stereo-controlled step. The results revealed the important role of the phenolic OH group in pre-organizing the complex of nitromethane and QN and stabilizing the in situ-generated nitronate and protonated QN. Three possible activation modes for C-C bond formation involving different coordination patterns of catalyst and substrates were studied, and it was found that both the ion pair-hydrogen bonding mode and the Bronsted acid-hydrogen bonding mode are viable, with the latter slightly preferred for the real catalytic system. The calculated enantiomeric excess (ee) favouring the S enantiomer is in good agreement with the experimental result. The high reactivity and enantioselectivity can be ascribed to the cooperative role of the multiple non-covalent interactions, including classical and non-classical H bonding as well as anionpi interactions. These results also highlight the importance of the inclusion of dispersion correction for achieving a reasonable agreement between theory and experiment for the current reaction. PMID- 27714328 TI - Dynamics of liquid plugs in prewetted capillary tubes: from acceleration and rupture to deceleration and airway obstruction. AB - The dynamics of individual liquid plugs pushed at a constant pressure head inside prewetted cylindrical capillary tubes is investigated experimentally and theoretically. It is shown that, depending on the thickness of the prewetting film and the magnitude of the pressure head, the plugs can either experience a continuous acceleration leading to a dramatic decrease of their size and eventually their rupture or conversely, a progressive deceleration associated with their growth and an exacerbation of the airway obstruction. These behaviors are quantitatively reproduced using a simple nonlinear model [Baudoin et al., Proc. Natl. Acad. Sci. U. S. A., 2013, 110, 859] adapted here for cylindrical channels. Furthermore, an analytical criterion for the transition between these two regimes is derived and successfully compared with extensive experimental data. The potential implications of this work for pulmonary obstructive diseases are discussed. PMID- 27714329 TI - Total synthesis of wewakazole B. AB - Wewakazole B is a novel cyclodecapeptide with highly potent cytotoxic activity isolated from a sample of M. producens collected from the Red Sea. It contains nine common and three modified amino acid residues. The first total synthesis of Wewakazole B was successfully achieved on a gram scale, unambiguously confirming its structure. Notable features include the careful choice of amino acid protecting groups and the construction of three different substituted oxazoles present in this natural product. PMID- 27714330 TI - Controlling swelling/deswelling of stimuli-responsive hydrogel nanofilms in electric fields. AB - The swelling/deswelling transition of pH-sensitive, electrode-grafted, hydrogel nanofilms when exposed to electric fields is studied by theoretical analysis. In acidic conditions, the response of these films to changes in pH is dominated by network-surface interactions, while intra-network electrostatic repulsions, which are highly modulated by the adsorption of salt ions, determine material response at a higher pH. Film thickness is a non-monotonic function of solution pH and displays a local maximum, a local minimum or both, depending on the salt concentration and the applied voltage. We suggest the use of these materials in the development of biosensors and control of enzyme activity.

AB - As a part of our ongoing synthetic quest to expand the frontiers of contemporary medicinal chemistry, we now report an expedient synthesis of a potentially useful bicyclo[1.1.1]pentane building block, 3-(pyrazin-2-yl)bicyclo[1.1.1]pentane-1 carboxylic acid. This report also showcases the application of this motif as a probe in a biological study. PMID- 27714332 TI - Magnetic field induced modulated phases in a ferrofluid lutidine silicone oil mixture. AB - A mixture of an ester based ferrofluid with silicone oil and 2,6-lutidine is exposed to an external magnetic field. We find a region of composition of the ternary mixture, where weak magnetic fields of the order of a few kA m-1 induce a modulated phase with a pattern characterized by equilibrium size droplets of the minority phase immersed into the extended majority phase. While the pattern resembles in many ways the pattern of immiscible magnetic fluids, the dependence of the characteristic parameters of the pattern on the magnetic field are completely different than in immiscible fluids. We theoretically explain the pattern formation as a magnetic field induced polymerization of magnetic particles into magnetic chains that goes along with a reduction of the entropy of mixing. This entropy reduction causes the Ostwald ripening of chains into mesoscopic droplets the size of which is limited by repulsive dipolar interactions between the chains. PMID- 27714333 TI - Interfacial rheology of polymer/carbon nanotube films co-assembled at the oil/water interface. AB - At appropriate conditions, water-dispersed acid-functionalized single-walled carbon nanotubes (SWCNTs) co-assemble at the oil/water interface with toluene dissolved amine-terminated polystyrene (PS-NH2) to form composite thin films displaying pronounced interfacial viscoelasticity. To probe this viscoelasticity, the films were examined under dilatational deformations of pendant drop tensiometry/rheometry, with storage and loss moduli recorded against frequency omega (0.003 < omega < 3 Hz) and time-dependent relaxation modulus recorded against time t (0.2 < t < 2000 s). Without the SWCNTs, PS-NH2-decorated interfaces have little dilatational stiffness, i.e., low storage modulus, but their stiffness grows as SWCNTs are added, reaching 50-100 mN m-1 at large omega. Two characteristic relaxation processes are identified in the composite films: a fast process (omega ~ 0.1-0.2 Hz) attributable to local structural relaxation of confined PS-NH2 and a slow process (t ~ 300-2000 s) attributable to component adsorption/desorption (or attachment/detachment). Among the variables that affect positions and strengths of these relaxations are SWCNT and PS-NH2 bulk concentrations as well as water phase pH. In frequency or timescale ranges intermediate between the two relaxations, the co-assembled films display "soft glass" behavior, with the storage and loss moduli characterized by nearly equal power-law exponents. The relaxation modulus, better able to probe terminal behavior, eventually decays to zero, revealing that the films are fundamentally fluid-like due to the slow relaxation, and in support of this conclusion, large strain compression-induced film wrinkles disappear at large t. PMID- 27714334 TI - Poroelastic indentation of mechanically confined hydrogel layers. AB - We report on the poroelastic indentation response of hydrogel thin films geometrically confined within contacts with rigid spherical probes of radii in the millimeter range. Poly(PEGMA) (poly(ethylene glycol) methyl ether methacrylate), poly(DMA) (dimethylacrylamide) and poly(NIPAM) (N isopropylacrylamide) gel films with thickness less than 15 MUm were grafted onto glass substrates using a thiol-ene click chemistry route. Changes in the indentation depth under constant applied load were monitored over time as a function of the film thickness and the radius of curvature of the probe using an interferometric method. In addition, shear properties of the indented films were measured using a lateral contact method. In the case of poly(PEGMA) films, we show that poroelastic indentation behavior is adequately described within the framework of an approximate contact model derived within the limits of confined contact geometries. This model provides simple scaling laws for the characteristic poroelastic time and the equilibrium indentation depth. Conversely, deviations from this model are evidenced for poly(DMA) and poly(NIPAM) films. From lateral contact experiments, these deviations are found to result from strong changes in the shear properties as a result of glass transition (poly(DMA)) or phase separation (poly(NIPAM)) phenomena induced by the drainage of the confined films squeezed between the rigid substrates. PMID- 27714335 TI - Clusters of red blood cells in microcapillary flow: hydrodynamic versus macromolecule induced interaction. AB - We present experiments on RBCs that flow through micro-capillaries under physiological conditions. The strong flow-shape coupling of these deformable objects leads to a rich variety of cluster formation. We show that the RBC clusters form as a subtle imbrication between hydrodynamic interactions and adhesion forces because of plasma proteins, mimicked by the polymer dextran. Clusters form along the capillaries and macromolecule-induced adhesion contributes to their stability. However, at high yet physiological flow velocities, shear stresses overcome part of the adhesion forces, and cluster stabilization due to hydrodynamics becomes stronger. For the case of pure hydrodynamic interaction, cell-to-cell distances have a pronounced bimodal distribution. Our 2D-numerical simulations on vesicles capture the transition between adhesive and non-adhesive clusters at different flow velocities. PMID- 27714336 TI - Nanotubular self-organization of amide dendrons with focal beta-sheet forming peptide units. AB - To develop rational design principles for a self-organized structure using dendron-peptide conjugates, a beta-sheet forming short peptide (VVLL) was introduced to the focal point of a second-generation amide dendron (2G-VVLL) and its self-organization characteristics were investigated. 2G-VVLL self-organized into a nanotubular structure in the aqueous phase. The twisted beta-sheet structure of the focal peptide unit was essential for the construction of the nanotubular structure. The design principle could be applied to another dendron peptide conjugate (2G-AAVV). These findings are expected to assist in the construction of novel precisely controlled nanoarchitectures using amide dendrons with focal peptide units. PMID- 27714337 TI - One-step formation of multiple Pickering emulsions stabilized by self-assembled poly(dodecyl acrylate-co-acrylic acid) nanoparticles. AB - In this study, a one-step generation of stable multiple Pickering emulsions using pH-responsive polymeric nanoparticles as the only emulsifier was reported. The polymeric nanoparticles were self-assembled from an amphiphilic random copolymer poly(dodecyl acrylate-co-acrylic acid) (PDAA), and the effect of the copolymer content on the size and morphology of PDAA nanoparticles was determined by dynamic light scattering (DLS) and transmission electron microscopy (TEM). The emulsification study of PDAA nanoparticles revealed that multiple Pickering emulsions could be generated through a one-step phase inversion process by using PDAA nanoparticles as the stabilizer. Moreover, the emulsification performance of PDAA nanoparticles at different pH values demonstrated that multiple emulsions with long-time stability could only be stabilized by PDAA nanoparticles at pH 5.5, indicating that the surface wettability of PDAA nanoparticles plays a crucial role in determining the type and stability of the prepared Pickering emulsions. Additionally, the polarity of oil does not affect the emulsification performance of PDAA nanoparticles, and a wide range of oils could be used as the oil phase to prepare multiple emulsions. These results demonstrated that multiple Pickering emulsions could be generated via the one-step emulsification process using self-assembled polymeric nanoparticles as the stabilizer, and the prepared multiple emulsions have promising potential to be applied in the cosmetic, medical, and food industries. PMID- 27714338 TI - Nanostickers for cells: a model study using cell-nanoparticle hybrid aggregates. AB - We present direct evidence that nanoparticles (NPs) can stick together cells that are inherently non-adhesive. Using cadherin-depleted S180 murine cells lines, which exhibit very low cell-cell adhesion, we show that NPs can assemble dispersed single cells into large cohesive aggregates. The dynamics of aggregation, which is controlled by diffusion and collision, can be described as a second-order kinetic law characterized by a rate of collision that depends on the size, concentration, and surface chemistry of the NPs. We model the cell-cell adhesion induced by the "nanostickers" using a three-state dynamical model, where the NPs are free, adsorbed on the cell membrane or internalized by the cells. We define a "sticking efficiency parameter" to compare NPs and look for the most efficient type of NP. We find that 20 nm carboxylated polystyrene NPs are more efficient nanostickers than 20 nm silica NPs which were reported to induce fast wound healing and to glue soft tissues. Nanostickers, by increasing the cohesion of tissues and tumors, may have important applications for tissue engineering and cancer treatment. PMID- 27714339 TI - Curvature induced hierarchical wrinkling patterns in soft bilayers. AB - Sinusoidal wrinkling will occur in a planar film-substrate bilayer when the uniaxial compressive strain imposed to the system exceeds a critical value. However, when a core-shell soft cylinder is subjected to axial compression, surface wrinkling patterns may evolve from the sinusoidal mode to the diamond like mode, depending on the modular ratio and the curvature of the system. Inspired by this phenomenon, we here propose a simple yet robust strategy to fabricate hierarchical wrinkling patterns by controlling the curvature of a film substrate system. To quantitatively understand the experimental results, a three dimensional finite element model has been built to track the wrinkling pattern evolution. Furthermore, a phase diagram is provided based on the theoretical analysis and finite element simulations, which may guide the experimental design. In addition, the wetting properties of the surface with hierarchical micropatterns fabricated using the proposed method are investigated. The results show that the hierarchical surface wrinkles lead to anisotropic wetting behavior, which can be tuned by controlling the imposed compressive strain. The tunable anisotropic wetting surface fabricated here may find a broad range of applications such as in the development of sensors, fluidic devices, micro reactors and biomedical devices. PMID- 27714340 TI - The unique role of bond length in the glassy dynamics of colloidal polymers. AB - Bond length is generally not considered as a controllable variable for molecular polymers. Hence, no experimental, simulation or theoretical research, to our knowledge, has examined the influence of bond length on the glassy dynamics of polymers. Recently, a new class of assembling materials called "colloidal polymers" has been synthesized. These colloidal polymers have advantages over molecular polymers in the visibility and flexibility of tuning, for example, the size and shape of the "monomers", the interaction, and the bond length. Dense suspension of colloidal polymers will become a very promising ideal model system for exploring the fundamental problems in the glass transition of chain "molecules". Here, we study the static structure and activated dynamics of hard sphere colloidal polymers by generalizing the colloidal nonlinear Langevin equation theory to colloidal polymers. Surprisingly, we find that the bond length plays a critical and unique role in many aspects. For instance, the universal relations of the characteristic local lengths and the activated barrier versus the "degree of supercooling", and the structural relaxation versus local vibrational motion are found to be dependent on bond length and independent of chain length and rigidity. We hope that our findings inspire future experimental and simulation research studies on the glassy dynamics of colloidal polymers. PMID- 27714341 TI - Humic-like substances from urban waste as auxiliaries for photo-Fenton treatment: a fluorescence EEM-PARAFAC study. AB - In this work, analysis of excitation-emission-matrices (EEM) has been employed to gain further insight into the characterization of humic like substances (HLS) obtained from urban wastes (soluble bio-organic substances, SBOs). In particular, complexation of these substances with iron and changes along a photo-Fenton process have been studied. Recorded EEMs were decomposed by using parallel factor analysis (PARAFAC). Three fluorescent components were identified by PARAFAC modeling of the entire set of SBO solutions studied. The EEM peak locations (lambdaex/lambdaem) of these components were 310-330 nm/400-420 nm (C1), 340-360 nm/450-500 nm (C2), and 285 nm/335-380 nm (C3). Slight variations of the maximum position of each component with the solution pH were observed. The interaction of SBO with Fe(iii) was characterized by determining the stability constants of the components with Fe(iii) at different pH values, which were in the order of magnitude of the ones reported for humic substances and reached their highest values at pH = 5. Photochemical experiments employing SBO and Fe(iii), with and without H2O2, showed pH-dependent trends for the evolution of the modeled components, which exhibited a strong correlation with the efficiency reported for the photo-Fenton processes in the presence of SBO at different pH values. PMID- 27714342 TI - Understanding the role of molar mass and stirring in polymer dissolution. AB - When a dry soluble polymer is put in contact with a large quantity of solvent, it swells and forms a transient gel, and eventually, yields a dilute solution of polymers. Everyday lab experience shows that when the molar mass is large, namely tens of times larger than entanglement mass, this dissolution process is slow and difficult and may require stirring. Here, in agreement with previous results, we found that the time needed to turn a dry grain into a dilute solution is not limited by water diffusion in the glassy or semi-crystalline dry polymer, but rather by the life-time of the transient gel made of entangled chains. In addition, we shed new light on the dissolution process by demonstrating that, in contrast to theoretical predictions, the gel life-time is not governed by reptation. We show instead that swelling is simply controlled by the osmotic pressure and the gel permeability until the overlap concentration is reached within the gel. At this stage, the gel turns into a dilute solution in which polymers are dispersed by natural convection. The observed dependence of the dissolution process on the molar mass therefore originates from the molar mass dependent overlap concentration. Under stirring, or forced convection, the polymer gel disappears at a higher critical concentration that depends on the shear rate. We suggest a description of the experimental data which uses the rheological flow curves of the solutions of the considered polymer. Inversely, dissolution times of polymer powders under stirring can be inferred from classical rheological measurements of the polymer solutions at varied concentrations.

AB - Macromolecular interactions are used to form supramolecular assemblies, including through the interaction of guest-host chemical pairs. Microstructural heterogeneity has been observed within such physical hydrogels; yet, systematic investigation of the microstructure and its determining inputs are lacking. Herein, we investigated the hierarchical self-assembly of hyaluronic acid (HA) modified by the guest-host pair adamantane (Ad-HA, guest) and beta-cyclodextrin (CD-HA, host), as well as with methacrylate groups to both tether fluorescent agents and to covalently stabilize the material structure. We observed microporous materials in the hydrated state, which temporally arose from initially homogenous hydrogels composed of the two polymers. Independent fluorescent labeling of Ad-HA and CD-HA demonstrated spatiotemporal co localization, indicative of guest-host polymer condensation on the microscale. The hydrogel void fractions and pore diameters were independently tuned through incubation time (0-7 days), polymer concentration (1.25-10 wt%), and polymer modification (25-50% Ad-HA modification). Void fractions as great as 93.3 +/- 2.4% were achieved and pore diameters ranged from 2.1 +/- 0.5 to 1025.4 +/- 209.4 MUm. The segregation of discrete solid and solute phases was measured with both atomic force microscopy and diffusive microparticle tracking analysis, where the solute phase contained only dilute polymer. The study represents a systematic investigation of hierarchical self-assembly in binary associating hydrogels, and provides insights on mechanisms that control microstructure within supramolecular hydrogels.

AB - The "ball-on-film" template is used to construct concentric rings on the surface of PMMA-QDs (polymethyl methacrylate - quantum dots) nanocomposite films via the evaporation of pure chloroform droplets, which are confined by a steel ball. The concentric rings consist of QDs, as revealed by the fluorescence images of the concentric rings. The photoluminescence intensity of the concentric rings increases with the increase of the distance to the ball center, suggesting that the amount of QDs accumulated around the contact line at individual stick state increases with the increase of the distance to the ball center. Both the wavelength and cross-sectional area (width) of the concentric rings increase approximately linearly with increasing distance to the ball center, independent of the ball size, the film thickness and the QDs concentration. For the PMMA-QDs nanocomposite films prepared from the same QDs concentration in chloroform, the thicker the PMMA-QDs nanocomposite film, the larger the wavelength for the same distance to the ball center. The effect of confinement of two steel balls on the surface patterns over the PMMA-QDs nanocomposite films is studied via a template of "two spheres on film". Symmetric surface patterns are formed. There exist two types of featureless zone between the two balls, depending on the distance between the two balls: one is the inner featureless zone and the other is the outer featureless zone. The size of both featureless zones increases with the increase of the ball distance. PMID- 27714346 TI - Structural behaviour and gene delivery in complexes formed between DNA and arginine-containing peptide amphiphiles. AB - We describe in depth the structure of complexes formed between DNA and two classes of arginine-containing peptide amphiphiles, namely, the lipopeptide PRW C16 (P = proline, R = arginine, W = tryptophan, C16 = C16 : 0 alkyl chain) and the bolaamphiphile RFL4FR (R = arginine, F = phenylalanine, L = leucine). A combination of X-ray and neutron scattering provided unprecedented insights into the local structure of these complexes. Lipopeptide-based complexes self assembled into layered structures with large-scale fractal features, hosting DNA in the interstices. Bola-amphiphile scaffolds were characterized by planar structures with DNA strands presumably sandwiched in-between peptide nanotapes. Importantly, complexation did not affect the structural integrity of DNA in either of the two complexes. The bolaamphiphile conjugates displayed high levels of molecular ordering in contrast to the liquid-crystalline features observed in lipopeptide assemblies. Peptide-DNA complexes were assessed for their potential as a means to deliver the reporter vector pEGFP-N1 into SW480 human colon carcinoma cells. Successfully transfected cells expressed green fluorescent protein. The potentiating effect of PRW-C16 on the cellular uptake of ectopic DNA was found to be much greater than that observed with RFL4FR. In contrast to the bolaamphiphile-based conjugate, the liquid-crystalline nature of the lipopeptide complex is likely to play a key role in DNA release and transfection efficiency since these weakly bound structures require lower energy expenditure during disassembly and load release.

AB - We identify distinct mechanisms controlling slowing of nanoparticle diffusion through complex media featuring both rigid geometrical confinement and soft mobile crowders. Towards this end, we use confocal microscopy and single particle tracking to probe the diffusion of 400 nm nanoparticles suspended in Newtonian water, in a Newtonian glycerol/water mixture, or in a non-Newtonian polymer solution through a model porous medium, a packed bed of microscale glass beads. The mobility of nanoparticles, as quantified by the long-time diffusion coefficient extracted from the particle mean-squared displacement, slows as the average pore size of the packed bed media decreases for both Newtonian and non Newtonian solutions. The distribution of particle displacements is non-Gaussian, consistent with the spatial heterogeneity of the geometrical confinement imposed by the packed bed. The slowing of nanoparticle mobility in all solutions follows the predictions of models that describe hydrodynamic interactions with the packed bed. In non-Newtonian solutions, depletion interactions due to the polymers near the glass beads result in temporary adsorption of particles onto the bead surface, as indicated by a stretched-exponential distribution of residence times. Our results therefore suggest that the confined diffusive dynamics of nanoparticles in polymer solutions is controlled by two competing mechanisms: hydrodynamic interactions between particles and spatial obstacles, which dictate the long-time slowing of diffusion, and depletion interactions between particles and confining walls due to the macromolecules, which control transient adsorption and hence alter the statistics of the short-time motion.

AB - The absence of entanglements, the more compact structure and the faster diffusion in melts of cyclic poly(ethylene oxide) (PEO) chains have consequences on their crystallization behavior at the lamellar and spherulitic length scales. Rings with molecular weight below the entanglement molecular weight (M < Me), attain the equilibrium configuration composed from twice-folded chains with a lamellar periodicity that is half of the corresponding linear chains. Rings with M > Me undergo distinct step-like conformational changes to a crystalline lamellar with the equilibrium configuration. Rings melt from this configuration in the absence of crystal thickening in sharp contrast to linear chains. In general, rings more easily attain their extended equilibrium configuration due to strained segments and the absence of entanglements. In addition, rings have a higher equilibrium melting temperature. At the level of the spherulitic superstructure, growth rates are much faster for rings reflecting the faster diffusion and more compact structure. With respect to the segmental dynamics in their semi-crystalline state, ring PEOs with a steepness index of ~34 form some of the "strongest" glasses.

AB - In this study, the attraction between large hard polystyrene (PS) spheres is studied by using three types of small microgels as bridging agents. One is a purely soft poly(N-isopropylacrylamide) (PNIPAM) microgel, the other two have a non-deformable PS hard core surrounded by a soft PNIPAM shell but are different in the core-shell ratio. The affinity for bridging the large PS spheres is provided and thus affected by the PNIPAM constituent in the microgels. The bridging effects caused by the microgels can be indirectly incorporated into their influence on the effective attraction interaction between the large hard spheres, since the size of the microgels is very small in comparison to the size of the PS hard spheres. At a given volume fraction of large PS spheres, they behave essentially as hard spheres in the absence of small microgels. By gradually adding the microgels, the large spheres are connected to each other through the bridging of small particles until the attraction strength reaches a maximum value, after which adding more small particles slowly decreases the effective attraction strength and eventually the large particles disperse individually when saturated adsorption is achieved. The aggregation and gelation behaviors triggered by these three types of small microgels are compared and discussed. A way to tune the strength and range of the short-range attractive potential via changing the softness of bridging microgels (which can be achieved either by using core-shell microgels or by changing the temperature) is proposed.

AB - A controlled configurational change of micro-clusters in suspensions is essential for many smart material applications. In this paper, the dynamic process of ferromagnetic microrod clusters (FMRCs) under an external magnetic field was studied as a function of the cluster size N and the applied field B. The FMRCs rearranged from a side-by-side raft-like structure to an end-to-end chain-like structure, originating from coupled motions through the field-driven alignment of both ferromagnetic microrods and FMRCs. A theoretical model based on an extension of a zig-zag chain was developed, and both the cluster length and orientation could be characterized by a retardation time constant tau, with a relationship tau ~ N2/B, which agrees well with the experimental results, tau ~ N2.2+/ 0.2/B0.8+/-0.1. Such a model can be used to predict other cluster dynamics or the magneto-elastic behavior of other soft matters consisting of FMRCs.

AB - The ability to form transient, self-assembling solid networks that 'cocoon' emulsion droplets on-demand allows new possibilities in the rapidly expanding area of microfluidic droplet-based materials science. In this communication, we demonstrate the spontaneous formation of extended colloidal networks that encase large microfluidic droplet ensembles, thus completely arresting droplet motion and effectively isolating each droplet from others in the ensemble. To do this, we employ molecular inclusion complexes of beta-cyclodextrin, which spontaneously form and assemble into colloidal solids at the droplet interface and beyond, via the outward diffusion of a guest molecule (dichloromethane) from the droplets. We illustrate the advantage of such transient network-based droplet stabilization in the area of pharmaceutical crystallization, where we are able to fabricate monodisperse spherical crystalline microgranules of 5-methyl-2-[(2 nitrophenyl)amino]-3-thiophenecarbonitrile (ROY), a model hydrophobic drug, with a dramatic enhancement of particle properties compared to conventional methods.

AB - This article reports an in situ UV-Vis-NIR diffuse reflectance (DR) spectroscopic and kinetic study of the photoformation and thermal annealing of light absorbing electronic point defects (color centers) in photochromic TiO2 in the temperature range 90-720 K using a simple laboratory-made cryostat-type accessory (for a Cary 5000 spectrophotometer equipped with an integrating sphere). The accessory also allowed for UV-Vis-NIR DR studies to be undertaken either in vacuum or in an oxygen atmosphere at significantly high temperatures (to 720 K) to assess dark chemical events occurring in photochromic titania with the participation of color centers. The DR spectral and kinetic measurements provided the opportunity to examine the separation of photoinduced charge carriers at traps and thermally stimulated carrier detrapping and recombination, as well as the response of color centers to oxidative/reductive treatments of photochromic TiO2. Kinetic results also demonstrate the applicability of the fabricated DR accessory as a high temperature reaction cell in the systematic study of the principal regularities in the formation and destruction of color centers in titania at various temperatures and gaseous atmospheres. PMID- 27714354 TI - The surface tells it all: relationship between volume and surface fraction of liquid dispersions. AB - The properties of liquid dispersions, such as foams or emulsions, depend strongly on the volume fraction phi of the continuous phase. Concentrating on the example of foams, we show experimentally and theoretically that phi may be related to the fraction phis of the surface at a wall which is wetted by the continuous phase - given an expression for the interfacial energy or osmotic pressure of the bulk system. Since the surface fraction phis can be readily determined from optical measurement and since there are good general approximations available for interfacial energy and osmotic pressure we thus arrive at an advantageous method of estimating phi. The same relationship between phi and phis is also expected to provide a good approximation of the fraction of the bubble or drop surface which is wetted by the continuous phase. This is a parameter of great importance for the rheology and ageing of liquid dispersions. PMID- 27714355 TI - Bacterial swarmer cells in confinement: a mesoscale hydrodynamic simulation study. AB - A wide spectrum of Peritrichous bacteria undergo considerable physiological changes when they are inoculated onto nutrition-rich surfaces and exhibit a rapid and collective migration denoted as swarming. Thereby, the length of such swarmer cells and their number of flagella increases substantially. In this article, we investigated the properties of individual E. coli-type swarmer cells confined between two parallel walls via mesoscale hydrodynamic simulations, combining molecular dynamics simulations of the swarmer cell with the multiparticle particle collision dynamics approach for the embedding fluid. E. coli-type swarmer cells are three-times longer than their planktonic counter parts, but their flagella density is comparable. By varying the wall separation, we analyze the confinement effect on the flagella arrangement, on the distribution of cells in the gap between the walls, and on the cell dynamics. We find only a weak dependence of confinement on the bundle structure and dynamics. The distribution of cells in the gap changes from a geometry-dominated behavior for very narrow to fluid-dominated behavior for wider gaps, where cells are preferentially located in the gap center for narrower gaps and stay preferentially next to one of the walls for wider gaps. Dynamically, the cells exhibit a wide spectrum of migration behaviors, depending on their flagella bundle arrangement, and ranges from straight swimming to wall rolling. PMID- 27714356 TI - Geometrical instability in the imbibition of a sphere. AB - We study the imbibition of a spherical porous aggregate. When the difference in pressure between the inside and the outside of the aggregate is large enough, the imbibition front becomes unstable. This instability leads to the acceleration of the imbibition process. In more complex geometries with non-constant curvatures, the imbibition becomes locally unstable in the regions with the highest curvatures, leading to spatially heterogeneous front velocities. PMID- 27714357 TI - Enhanced photocatalytic degradation of phenol over anatase TiO2 in neutral water on addition of iron(iii) substituted polyoxotungstate. AB - PW12O40-type polyoxometalates have been widely used as electron mediators of TiO2 photocatalysis for organic degradation in water, but they are stable only at pH 1 2, which greatly limits their application for water treatment. Herein we report an iron(iii)-substituted PW11O39 (PW11Fe) capable of mediating the photocatalytic degradation of phenol and 2,4-dichlorophenol in an aerated aqueous suspension of anatase TiO2 at pH 2.0-7.2. As the initial concentration of PW11Fe or the initial pH of the suspension increased, the rate of phenol degradation increased, and then decreased. A maximum reaction rate was achieved at 2.0 mM PW11Fe and pH 5.5, which was 3.9 times higher than that measured without PW11Fe. In all cases, the rates of phenol degradation were of the first order in phenol, implying the recycling behavior of PW11Fe. Through electrochemical measurement, a possible mechanism is proposed, which involves the interfacial electron transfer from the irradiated TiO2 to PW11Fe, and the reduction of O2 by the reduced PW11Fe. This would improve the efficiency of the charge separation of TiO2, and consequently increase the rate of phenol degradation at interfaces. PMID- 27714358 TI - Segmental dynamics in lamellar phases of tapered copolymers. AB - Recent experiments have reported that the lamellar phase of salt-doped tapered copolymers exhibit higher ionic conductivity compared to those seen in similar morphologies of diblock copolymers. Such observations were in turn rationalized by invoking the corresponding glass transition temperature of the segregated copolymers. In this work we report the results of coarse-grained molecular dynamics simulations to identify the mechanisms underlying such characteristics. Explicitly, we probe the combined influences of the degree of segregation and the disparity in mobilities of the segments of the two blocks, upon the local relaxation dynamics of tapered copolymers segregated in lamellar phases. Our results show that the local dynamics of tapered copolymers depend on two independent factors, viz., the degree of segregation of such copolymers relative to their order-disorder transition temperature, and the relative mobilities (glass transition temperatures) of the two blocks. In qualitative correspondence with experiments, we find that for appropriate combinations of mobility ratios and degree of segregation, the lamellar phases of tapered copolymers can exhibit faster local segmental dynamics compared to diblock copolymers. PMID- 27714359 TI - Tracer diffusion in a sea of polymers with binding zones: mobile vs. frozen traps. AB - We use molecular dynamics simulations to investigate the tracer diffusion in a sea of polymers with specific binding zones for the tracer. These binding zones act as traps. Our simulations show that the tracer can undergo normal yet non Gaussian diffusion under certain circumstances, e.g., when the polymers with traps are frozen in space and the volume fraction and the binding strength of the traps are moderate. In this case, as the tracer moves, it experiences a heterogeneous environment and exhibits confined continuous time random walk (CTRW) like motion resulting in a non-Gaussian behavior. Also the long time dynamics becomes subdiffusive as the number or the binding strength of the traps increases. However, if the polymers are mobile then the tracer dynamics is Gaussian but could be normal or subdiffusive depending on the number and the binding strength of the traps. In addition, with increasing binding strength and number of polymer traps, the probability of the tracer being trapped increases. On the other hand, removing the binding zones does not result in trapping, even at comparatively high crowding. Our simulations also show that the trapping probability increases with the increasing size of the tracer and for a bigger tracer with the frozen polymer background the dynamics is only weakly non Gaussian but highly subdiffusive. Our observations are in the same spirit as found in many recent experiments on tracer diffusion in polymeric materials and question the validity of using Gaussian theory to describe diffusion in a crowded environment in general. PMID- 27714360 TI - Dendrimer assisted dispersion of carbon nanotubes: a molecular dynamics study. AB - Various unique physical, chemical, mechanical and electronic properties of carbon nanotubes (CNTs) make them very useful materials for diverse potential application in many fields. Experimentally synthesized CNTs are generally found in bundle geometry with a mixture of different chiralities and present a unique challenge to separate them. In this paper we have proposed the PAMAM dendrimer to be an ideal candidate for this separation. To estimate the efficiency of the dendrimer for the dispersion of CNTs from the bundle geometry, we have calculated potential of mean forces (PMF). Our PMF study of two dendrimer-wrapped CNTs shows lesser binding affinity compared to the two bare CNTs. PMF study shows that the binding affinity decreases for non-protonated dendrimer, and for the protonated case the interaction is fully repulsive in nature. For both the non-protonated as well as protonated cases, the PMF increases gradually with increasing dendrimer generations from 2 to 4 compared to the bare PMF. We have performed PMF calculations with (6,5) and (6,6) chirality to study the chirality dependence of PMF. Our study shows that the PMFs between two (6,5) and two (6,6) CNTs respectively are ~-29 kcal mol-1 and ~-27 kcal mol-1. Calculated PMF for protonated dendrimer-wrapped chiral CNTs is more compared to the protonated dendrimer-wrapped armchair CNTs for all the generations studied. However, for non protonated dendrimer-wrapped CNTs, such chirality dependence is not very prominent. Our study suggests that the dispersion efficiency of the protonated dendrimer is more compared to the non-protonated dendrimer and can be used as an effective dispersing agent for the dispersion of CNTs from the bundle geometry. PMID- 27714361 TI - Fracture toughness of hydrogels: measurement and interpretation. AB - The fracture mechanics of hydrogels, especially those with significantly enhanced toughness, has attracted extensive research interests. In this article we discuss the experimental measurement and theoretical interpretation of the fracture toughness for soft hydrogels. We first review the definition of fracture toughness for elastic materials, and the commonly used experimental configurations to measure it. In reality most gels are inelastic. For gels that are rate insensitive, we discuss how to interpret the fracture toughness associated with two distinct scenarios: crack initiation and steady-state crack propagation. A formulation to estimate energy dissipation during steady-state crack propagation is developed, and connections to previous models in the literature are made. For gels with rate-dependent behaviors, we review the physical mechanisms responsible for the rate-dependence, and outline the difficulties to rigorously define the fracture toughness for both crack initiation and propagation. We conclude by discussing a few fundamental questions on the fracture of tough gels that are yet to be answered. PMID- 27714362 TI - Solvent effects on the fracture of chemically crosslinked gels. AB - We have investigated how the fracture behavior of a polyacrylamide hydrogel is affected by different types of solvents poured into its crack tips. We obtained the following results: first, when water (good solvent or reaction solvent for the polyacrylamide gel) is poured, the fracture energy Gamma becomes smaller than that measured in air for small crack velocities V (V <= 10 mm s-1). Second, when good solvents other than water are poured, Gamma is enhanced for a large V region (5 <= V <= 60 mm s-1), but this effect is not observed for smaller V; Gamma(V) in good solvents converges to that in water as V -> 0. Third, when ethanol (poor solvent for polyacrylamide) is poured, stick-slip-like crack propagation appears in the entire V range, and Gamma calculated from the time-average of the oscillating tearing forces is larger than that in air or in other solvents. We discuss the results on the basis of diffusion dynamics around the crack tips of the gel. PMID- 27714363 TI - Programmable mechanical metamaterials: the role of geometry. AB - We experimentally and numerically study the role of geometry for the mechanics of biholar metamaterials, which are quasi-2D slabs of rubber patterned by circular holes of two alternating sizes. We recently showed how the response to uniaxial compression of these metamaterials can be programmed by lateral confinement. In particular, there is a range of confining strains epsilonx for which the resistance to compression becomes non-trivial-non-monotonic or hysteretic-in a range of compressive strains epsilony. Here we show how the dimensionless geometrical parameters t and chi, which characterize the wall thickness and size ratio of the holes that pattern these metamaterials, can significantly tune these ranges over a wide range. We study the behavior for the limiting cases where the wall thickness t and the size ratio chi become large, and discuss the new physics that arises there. Away from these extreme limits, the variation of the strain ranges of interest is smooth with porosity, but the variation with size ratio evidences a cross-over at low chi from biholar to monoholar (equal sized holes) behavior, related to the elastic instabilities in purely monoholar metamaterials. Our study provides precise guidelines for the rational design of programmable biholar metamaterials, tailored to specific applications, and indicates that the widest range of programmability arises for moderate values of both t and chi. PMID- 27714364 TI - Analysis of the aging effects on the viscoelasticity of alginate gels. AB - The effect of aging on the mechanical behaviour of ionically cross-linked alginate gels is studied in detail. Relaxation experiments upon both unconfined compression and torsion are performed on samples at different aging times. The elastic moduli of the gel are found to increase with the aging time, whereas the internal (constitutive) mechanism of the relaxation of the solid component of the gel is found to be unaffected by aging. It is demonstrated that the Linear Visco Elastic Stress/Diffusion Coupling model [D. Larobina, F. Greco, J. Chem. Phys., 2012, 136, 134904], recently developed by two of the present authors, is able to quantitatively reproduce the experimental data for differently aged samples, at early-to-intermediate relaxation times. Moreover, it is shown that the gel always undergoes a spontaneous expulsion of water (syneresis) and some spontaneous deformation for a sufficiently long observation time, even in the absence of any externally imposed strain. The latter phenomenology progressively slows down with increasing of the gel age. By proper time shifting of the late relaxation decays, i.e., by properly defining an "effective time", master curves can be obtained in all cases, with all data pertaining to differently aged samples collapsing on a single relaxation law for each deformation history. The dependence of the shift factors on the aging time is found to follow a power law behavior, with an exponent of 1.39. PMID- 27714365 TI - Mean-field beyond mean-field: the single particle view for moderately to strongly coupled charged fluids. AB - In a counter-ion only charged fluid, Coulomb coupling is quantified by a single dimensionless parameter. Yet, the theoretical treatment of moderately to strongly coupled charged fluids is a difficult task, central to the understanding of a wealth of soft matter problems, including biological systems. We show that the corresponding coupling regime can be remarkably well described by a single particle treatment, which, at variance with previous works, takes due account of inter-ionic interactions. To this end, the prototypical problem of a planar charged dielectric interface is worked out. Testing our predictions against Monte Carlo simulation data reveals an excellent agreement. PMID- 27714366 TI - A highly stretchable double-network composite. AB - Inspired by the toughening mechanism of double-network (DN) hydrogels, a soft composite consisting of a fabric mesh and VHB tape layers was fabricated. The composite was as stiff as the fabric mesh, and as stretchable as the VHB tape. At certain compositions, the composite was significantly stronger and tougher than the base materials. The extensibility and toughness of the composite can be attributed to a damage delocalization mechanism similar to that of the DN gels. In the partially damaged regions, the fabric mesh fragmented into small islands, surrounded by the highly stretched VHB tapes. Accommodated by the finite sliding at the interface, the large deformation of the composite is highly non-affine. Just as the DN gels, the coexistence of the partially damaged and intact regions resulted in a stable necking in the composite when subjected to uniaxial tension. The propagation of the necking zone corresponded to a plateau on the stress stretch curve. During cyclic loading, the composite also exhibited stress hysteresis with almost recoverable strain, similar to that in a DN gel. To rationalize these observations and to better understand the underlying physical mechanism, a simple 1D model has been developed for the damage evolution process in the composite. The predictions of the model have achieved good agreement with the measured properties of the composite of various compositions. Furthermore, the composite itself may also be regarded as a macroscopic model when studying the properties and toughening mechanism of the DN gels.

AB - Low molecular weight gelator hydrogels provide a viable alternative to traditional polymer based drug delivery platforms, owing to their tunable stability and in most cases inherent biocompatibility. Here we report the first self-healing nucleoside hydrogel using N4-octanoyl-2'-deoxycytidine (0.5% w/v) for drug delivery. The hydrogel's cross-linked nanofibrillar structure, was characterised using oscillatory rheology and confirmed using SEM and TEM imaging. The potential of this gel for drug delivery was explored in vitro using fluorescently labelled tracers. Cell viability assays were conducted using pancreatic cell lines which tolerated the gels well; whilst no adverse effects on the viability or proliferation of cells were observed for fibroblast cell lines. PMID- 27714368 TI - Reorientation mechanisms of block copolymer/CdSe quantum dot composites under application of an electric field. AB - Time- and temperature-resolved in situ birefringence measurements were applied to analyze the effect of nanoparticles on the electric field-induced alignment of a microphase separated solution of poly(styrene)-block-poly(isoprene) in toluene. Through the incorporation of isoprene-confined CdSe quantum dots the reorientation behavior is altered. Particle loading lowers the order-disorder transition temperature, and increases the defect density, favoring nucleation and growth as an alignment mechanism over rotation of grains. The temperature dependent alteration in the reorientation mechanism is analyzed via a combination of birefringence and synchrotron SAXS. The detailed understanding of the effect of nanoparticles on the reorientation mechanism is an important prerequisite for optimization of electric-field-induced alignment of block copolymer/nanoparticle composites where the block copolymer guides the nanoparticle self-assembly into anisotropic structures. PMID- 27714369 TI - Thermo-responsive shape and optical memories of photonic composite films enabled by glassy liquid crystalline polymer networks. AB - We propose a novel shape and optical memories of a photonic composite film based on a silica opal photonic crystal (PC) template and a liquid crystal polymer network (LCN). Here, the photonic composite film was fabricated by introducing a LCN precursor into a silica opal PC template, followed by UV photo-polymerization and then by the removal of the template. The obtained bilayer-structure photonic film was found to spontaneously form a three-dimensional (3D) temporary bending shape in response to heating, and thus the corresponding reflection color of the photonic composite film shows a blue shift during bending deformation. The inherent mechanisms of these two observations could be attributed to the variations of the LC molecule orientation and the light reflection in the photonic composite film during the thermal process. More intriguingly, the resulting temporary bending shape was fixed by applying mechanical force during slowly cooling down to the room temperature or autonomously fixed by a rapid cooling in liquid nitrogen. Additionally, this temporary state could restore back to the permanent flat shape when the film is cooled from the heat source without an external force. Finally, more complex 3D shape-memory samples could also be achieved by simply controlling the LC alignment or designing the sample geometry. This work opens up a new way to develop a novel shape-memory polymer photonic film. PMID- 27714370 TI - Thermoosmotic microfluidics. AB - Microchannels with asymmetrically ratcheted walls are here shown to behave as effective and versatile microfluidic pumps if locally heated. When the boundary walls have different temperatures, the confined liquid experiences a temperature gradient along the sawtooth edges, which can induce a thermoosmotic flow. A mesoscale molecular simulation approach is here employed to investigate the flows which are contrasted using an analytical approach. Microchannels can be composed by one or two ratcheted walls which can be straight or cylindrical. Varying the channel geometry can not only change the overall fluid flux, but also vary the flow patters from shear to capillary type, or even to extensional type flows. This scheme does not require multiphase fluids or any movable channel parts, although they are possible to be implemented. The proposed principle is then very versatile to locally manipulate complex fluids, and a promising tool to recover waste heat, to facilitate cooling of microchips, and to manufacture portable lab on-a-chip devices.

AB - Gemini supra-amphiphiles with different spacer lengths, [M-n-M]2+@2[DBS]- (n = 2, 6, 10), were easily constructed. The conformational flexibility and hydrophobicity of the spacer group can be effectively tailored through regulating the spacer length, leading to the fine control of the topologies and subsequent hierarchical self-assemblies of [M-n-M]2+@2[DBS]-. Vesicles are primarily fabricated by [M-n-M]2+@2[DBS]-, and then successively fused into vesicle clusters, nanotubes, and planar bilayers, whose bilayer curvatures are gradually decreased, with increasing spacer length. Coating [M-10-M]2+ with beta-CD can reduce the flexibility and hydrophobicity of the decyl spacer, resulting in the reversion from planar bilayers to vesicles. Furthermore, stable aqueous two-phase systems (ATPSs) that spontaneously formed via vesicle fusion in the solutions of [M-n-M]2+@2[DBS]- (n = 6, 10) can act as functional supramolecular systems in the isolation and purification of oil-soluble biomaterials. PMID- 27714372 TI - Electrokinetics of nanoparticle gel-electrophoresis. AB - Gel-electrophoresis has been demonstrated in recent decades to successfully sort a great variety of nanoparticles according to their size, charge, surface chemistry, and corona architecture. However, quantitative theoretical interpetations have been limited by the number and complexity of factors that influence particle migration. Theoretical models have been fragmented and incomplete with respect to their counterparts for free-solution electrophoresis. This paper unifies electrokinetic models that address complex nanoparticle corona architectures, corona and gel charge regulation (e.g., by the local pH), multi component electrolytes, and non-linear electrostatics and relaxation effects. By comprehensively addressing the electrokinetic aspects of the more general gel electrophoresis problem, in which short-ranged steric interactions are significant, a stage is set to better focus on the physicochemical and steric factors. In this manner, it is envisioned that noparticle gel-electrophoresis may eventually be advanced from a nanoparticle-characterization tool to one that explicitly probes the short-ranged interactions of nanoparticles with soft networks, such as synthetic gels and biological tissues. In this paper, calculations are undertaken that identify a generalized Huckel limit for nanoparticles in low-conductivity gels, and a new Smoluchowski limit for polyelectrolyte-coated particles in high-conductivity gels that is independent of the gel permeability. Also of fundamental interest is a finite, albeit small, electrophoretic mobility for uncharged particles in charged gels. Electrophoretic mobilities and drag coefficients (with electroviscous effects) for nanoparticles bearing non-uniform coronas show that relaxation effects are typically weak for the small nanoparticles (radius ~3-10 nm) to which gel-electrophoresis has customarily been applied, but are profound for the larger nanoparticles (radius ? 40 nm in low conductivity gels) to which passivated gel-electrophoresis experiments have recently been applied. To demonstrate its practical application, the model is applied to (pH charge regulating) carboxylated polystyrene nanospheres in low-density passivated agarose gels (weak steric effects). This furnishes a new theoretical interpretation of literature data for which a finite diffuse-layer-thickness, pH-charge regulation, high charge, and relaxation effects dominate over the steric influences. PMID- 27714373 TI - Coarse-grained modeling of crystal growth and polymorphism of a model pharmaceutical molecule. AB - We describe a systematic coarse-graining method to study crystallization and predict possible polymorphs of small organic molecules. In this method, a coarse grained (CG) force field is obtained by inverse-Boltzmann iteration from the radial distribution function of atomistic simulations of the known crystal. With the force field obtained by this method, we show that CG simulations of the drug phenytoin predict growth of a crystalline slab from a melt of phenytoin, allowing determination of the fastest-growing surface, as well as giving the correct lattice parameters and crystal morphology. By applying meta-dynamics to the coarse-grained model, a new crystalline form of phenytoin (monoclinic, space group P21) was predicted which is different from the experimentally known crystal structure (orthorhombic, space group Pna21). Atomistic simulations and quantum calculations then showed the polymorph to be meta-stable at ambient temperature and pressure, and thermodynamically more stable than the conventional orthorhombic crystal at high pressure. The results suggest an efficient route to study crystal growth of small organic molecules that could also be useful for identification of possible polymorphs as well. PMID- 27714374 TI - Hydrodynamic oscillations and variable swimming speed in squirmers close to repulsive walls. AB - We present a lattice Boltzmann study of the hydrodynamics of a fully resolved squirmer, confined in a slab of fluid between two no-slip walls. We show that the coupling between hydrodynamics and short-range repulsive interactions between the swimmer and the surface can lead to hydrodynamic trapping of both pushers and pullers at the wall, and to hydrodynamic oscillations in the case of a pusher. We further show that a pusher moves significantly faster when close to a surface than in the bulk, whereas a puller undergoes a transition between fast motion and a dynamical standstill according to the range of the repulsive interaction. Our results critically require near-field hydrodynamics and demonstrate that far field hydrodynamics is insufficient to give even a qualitatively correct account of swimmer behaviour near walls. Finally our simulations suggest that it should be possible to control the density and speed of squirmers at a surface by tuning the range of steric and electrostatic swimmer-wall interactions. PMID- 27714375 TI - The architecture of the adsorbed layer at the substrate interface determines the glass transition of supported ultrathin polystyrene films. AB - To elucidate the mechanism underlying the effect of polymer/solid interfacial interactions on the dynamics of thin polymer films, the glass transition of thin end-functionalized polystyrene films supported on SiO2-Si, such as proton terminated PS (PS-H), alpha,omega-dicarboxy-terminated PS (PS-COOH), and alpha,omega-dihydroxyl-terminated PS (PS-OH), was investigated. All the PS films exhibited a substantial depression in Tg with decreasing film thickness, while the extent of such depression was strongly dependent on the chemical structure of the end groups and molecular weights. It was found that T - T of the various PS films increased linearly with increasing hads/Rg, in which hads is the thickness of the interfacial adsorbed layer and Rg is the radius of gyration of PS. The hads/Rg is a direct reflection of the macromolecular chain conformation within the adsorbed layer which was affected by its end groups and molecular weights. These findings are in line with the work of Napolitano, and present direct experimental evidence. PMID- 27714376 TI - Shape oscillations of particle-coated bubbles and directional particle expulsion. AB - Bubbles stabilised by colloidal particles can find applications in advanced materials, catalysis and drug delivery. For applications in controlled release, it is desirable to remove the particles from the interface in a programmable fashion. We have previously shown that ultrasound waves excite volumetric oscillations of particle-coated bubbles, resulting in precisely timed particle expulsion due to interface compression on a ultrafast timescale [Poulichet et al., Proc. Natl. Acad. Sci. U. S. A., 2015, 112, 5932]. We also observed shape oscillations, which were found to drive directional particle expulsion from the antinodes of the non-spherical deformation. In this paper we investigate the mechanisms leading to directional particle expulsion during shape oscillations of particle-coated bubbles driven by ultrasound at 40 kHz. We perform high-speed visualisation of the interface shape and of the particle distribution during ultrafast deformation at a rate of up to 104 s-1. The mode of shape oscillations is found to not depend on the bubble size, in contrast with what has been reported for uncoated bubbles. A decomposition of the non-spherical shape in spatial Fourier modes reveals that the interplay of different modes determines the locations of particle expulsion. The n-fold symmetry of the dominant mode does not always lead to desorption from all 2n antinodes, but only those where there is favourable alignment with the sub-dominant modes. Desorption from the antinodes of the shape oscillations is due to different, concurrent mechanisms. The radial acceleration of the interface at the antinodes can be up to 105-106 ms 2, hence there is a contribution from the inertia of the particles localised at the antinodes. In addition, we found that particles migrate to the antinodes of the shape oscillation, thereby enhancing the contribution from the surface pressure in the monolayer.

AB - Chemically active colloids generate changes in the chemical composition of their surrounding solution and thereby induce flows in the ambient fluid which affect their dynamical evolution. Here we study the many-body dynamics of a monolayer of spherically symmetric active particles trapped at a fluid-fluid interface. To this end we consider a model for the large-scale spatial distribution of particles which incorporates the direct pair interaction (including also the capillary interaction which is caused specifically by the interfacial trapping) as well as the effect of hydrodynamic interactions (including the Marangoni flow induced by the response of the interface to the chemical activity). The values of the relevant physical parameters for typical experimental realizations of such systems are estimated and various scenarios, which are predicted by our approach for the dynamics of the monolayer, are discussed. In particular, we show that the chemically-induced Marangoni flow can prevent the clustering instability driven by the capillary attraction. PMID- 27714378 TI - A new model for fluid velocity slip on a solid surface. AB - A general adsorption model is developed to describe the interactions between near wall fluid molecules and solid surfaces. This model serves as a framework for the theoretical modelling of boundary slip phenomena. Based on this adsorption model, a new general model for the slip velocity of fluids on solid surfaces is introduced. The slip boundary condition at a fluid-solid interface has hitherto been considered separately for gases and liquids. In this paper, we show that the slip velocity in both gases and liquids may originate from dynamical adsorption processes at the interface. A unified analytical model that is valid for both gas solid and liquid-solid slip boundary conditions is proposed based on surface science theory. The corroboration with the experimental data extracted from the literature shows that the proposed model provides an improved prediction compared to existing analytical models for gases at higher shear rates and close agreement for liquid-solid interfaces in general. PMID- 27714379 TI - Determination of equilibrium and rate constants for complex formation by fluorescence correlation spectroscopy supplemented by dynamic light scattering and Taylor dispersion analysis. AB - The equilibrium and rate constants of molecular complex formation are of great interest both in the field of chemistry and biology. Here, we use fluorescence correlation spectroscopy (FCS), supplemented by dynamic light scattering (DLS) and Taylor dispersion analysis (TDA), to study the complex formation in model systems of dye-micelle interactions. In our case, dyes rhodamine 110 and ATTO-488 interact with three differently charged surfactant micelles: octaethylene glycol monododecyl ether C12E8 (neutral), cetyltrimethylammonium chloride CTAC (positive) and sodium dodecyl sulfate SDS (negative). To determine the rate constants for the dye-micelle complex formation we fit the experimental data obtained by FCS with a new form of the autocorrelation function, derived in the accompanying paper. Our results show that the association rate constants for the model systems are roughly two orders of magnitude smaller than those in the case of the diffusion-controlled limit. Because the complex stability is determined by the dissociation rate constant, a two-step reaction mechanism, including the diffusion-controlled and reaction-controlled rates, is used to explain the dye micelle interaction. In the limit of fast reaction, we apply FCS to determine the equilibrium constant from the effective diffusion coefficient of the fluorescent components. Depending on the value of the equilibrium constant, we distinguish three types of interaction in the studied systems: weak, intermediate and strong. The values of the equilibrium constant obtained from the FCS and TDA experiments are very close to each other, which supports the theoretical model used to interpret the FCS data. PMID- 27714380 TI - Concentration-induced planar-to-homeotropic anchoring transition of stiff ring polymers on hard walls. AB - We study the structure and interfacial ordering of stiff ring polymers close to repulsive walls. For this purpose, we employ an anisotropic effective model in which the rings are pictured as soft, penetrable discs [P. Poier, C. N. Likos, A. J. Moreno and R. Blaak, Macromolecules, 2015, 48, 4983]. We have studied this model in the bulk and in the presence of a wall, employing Density Functional Theory and computer simulations. While the Ornstein-Zernike equation in combination with the Hypernetted Chain Approximation gives results that are in quantitative agreement with computer simulations, a simple Mean Field approximation strongly overestimates the interaction between the effective particles in the bulk. We discover that by increasing density one can induce a reorientation of the effective rings in the vicinity of a wall, which prefer to orient themselves parallel to the surface (face-on or planar) for low densities rho and reorient orthogonal to the wall (edge-on or homeotropic) for higher values of rho. This transition in the surface-structure can be observed in both computer simulations, as well as in an appropriate density functional theory. We trace its physical origin in the penetrable character of the rings, which allows for a reduction of the surface tension contribution due to ring-ring interactions upon the emergence of homeotropic ordering on the wall and increasing the density of the system. PMID- 27714381 TI - Amphiphilic BODIPY derivatives: the solvophobic effect on their photophysical properties and bioimaging in living cells. AB - Three novel amphiphilic BODIPY derivatives were prepared and their photophysical properties in THF/water mixtures with varying fractions of water were investigated. BDP-1 could self-assemble into different vesicle architectures in aqueous solution, while BDP-2 and BDP-3 with more hydrophilic abilities formed spherical and worm-like micelles. The BODIPY derivatives could be absorbed by HeLa cells and showed no apparent toxicity during the course of the test. In particular, unlike traditional amines or morpholinyl functionalized lysosome fluorescent probes, BDP-1 nanovesicles without targeted groups exhibit red emission and show effective lysosome biological imaging. Co-staining experiments with lysosome specific trackers further confirmed the disassembly of BDP-1 nanovesicles in lysosomes. This research provides a new avenue of using probes without targeting the structural unit to stain special organelles and shows potential applications in cell imaging fields. PMID- 27714382 TI - Preparation and attachment of liquid-infused porous supra-particles to liquid interfaces. AB - We prepared model porous composite supra-particles and investigated the effect of the initial infused fluid phase on their attachment at the liquid-fluid interface. We used a simple method for fabrication of millimetre-sized spherical porous supra-particles from much smaller monodisperse latex microparticles as building blocks by evaporation of a polystyrene sulphate latex suspension on a hot super-hydrophobic surface. We annealed the dried supra-particles at the polymer's glass transition temperature to fuse partially their latex particle building blocks. Spherical porous supra-particles were produced above 40 wt% initial concentration of the latex particles in the suspension, which had a rough surface, with a porous and amorphous structure. We controlled the supra-particle size by varying the initial volume of the latex suspension drop, the latex particle concentration and the drop evaporation temperature. This preparation technique allowed limited control over the porosity of the supra-particles by varying the initial concentration of the latex particle suspension, the rate of evaporation and the annealing temperature. We characterised the surface morphology and the inner structure of supra-particles by SEM imaging. We report for the first time results of an MRI study of supra-particles attached to an air water or an oil-water interface, which indicated that only the surface layer of the building block particles attaches to the liquid interface while the pore fluid was not displaced by the outer fluid. We observed that supra-particles infused with water had different wettability and attachment positions at the oil water interface compared with the same particles infused with oil. Similarly, the infusion of the porous supra-particles with water led to a different attachment at the air-water interface compared to the attachment of the same supra-particle when dry. The fundamental importance of this result is that the porous particles (or colloid particle agglomerates) may give an oil-in-water or water-in-oil Pickering emulsion depending on whether they are initially impregnated with oil or water. The results of this study are relevant for particle-stabilised emulsions and foams in a range of pharmaceutical, food and cosmetic formulations as well as ore flotation.

AB - The New South Wales School Students Health Behaviours Survey (2014) reported a substantial reduction in students aged 12-17 years reporting that they had ever consumed alcohol, from 82.7% in 2005 to 65.1% in 2014. Similar downward trends are reported nationally and internationally. Although overall consumption is declining, national recommendations maintain that it is safest for young people to not drink at all; however, 17% of all young people in Australia consumed alcohol in the past 7 days, with 6% consuming at a significant risk of harm. The factors that influence young people's uptake of alcohol are complex, including biological and broader social factors. This paper identifies some of the diverse influences on young people's alcohol consumption, and policies and programs that support healthy behaviours. PMID- 27714385 TI - Estimating prevalence of drug and alcohol presentations to hospital emergency departments in NSW, Australia: impact of hospital consultation liaison services. AB - The impact of drug and alcohol misuse has been the subject of widespread media discussion in the past year, particularly in the context of restricted alcohol trading hours in an effort to reduce alcohol-fuelled violence. A recent study evaluating NSW Health's drug and alcohol consultation liaison (CL) services1 demonstrates how pervasive drug and alcohol problems are, and the impact they have on the health system. This paper highlights how expanding CL services to fill current unmet need could deliver a range of benefits to patients and hospitals. PMID- 27714386 TI - The impact of alcohol pharmacotherapies on public health in Australia is limited by low prescribing rates. AB - Alcohol use disorders are among the most common and disabling problems in Australia. A number of pharmacotherapies available in Australia have been shown to be effective and are subsidised through the Australian Government's Pharmaceutical Benefits Scheme. The uptake of these medicines is poor, and the majority of those who start treatment do not complete the recommended course. Use of these medicines is significantly lower in regions that are disadvantaged or remote, and in patients who are younger. Taken together, these factors limit the potential benefit to population health from treatment of alcohol use disorders. Barriers to treatment have been identified at the level of the patient, the provider, the medicine and the healthcare system. An integrated strategy may be required to overcome these barriers. PMID- 27714387 TI - Impacts of changes to trading hours of liquor licences on alcohol-related harm: a systematic review 2005-2015. AB - BACKGROUND: Legislative limits on trading hours for licensed premises have a long history in Australia as a key policy approach to managing alcohol-related problems. In recent years, following substantial extensions to permitted hours of sale, there has been renewed attention to policies aimed at reducing late-night trading hours. Restrictions on on-premise alcohol sales have been implemented in Australia after 3.30 am in Newcastle, and after 3 am in Kings Cross and the Sydney central business district in New South Wales. In July 2016, similar restrictions were introduced state-wide after 2 am, or 3 am in 'safe night precincts', in Queensland. Similar policy changes have occurred internationally (e.g. in the UK and the Nordic countries) and there is a growing body of research examining the impacts of trading hour policies on alcohol-related harm. Although there has been a series of reviews of the research in this area, the most recent is now 5 years old and limited to studies published before March 2008. Objective and importance of study: To examine recent (2005-2015) research about the impact of changing the hours of sale of alcohol on alcohol-related harms. The ongoing public discussion about trading hours policy in Australia can benefit from an up to-date and comprehensive review of the research. METHODS: Systematic review of the literature that considered the impact of policies that extended or restricted trading hours. MEDLINE, Core Collection, PsychINFO and EMBASE databases were searched from January 2005 to December 2015. Articles were summarised descriptively, focusing on studies conducted in Australia and published since the previous reviews. RESULTS: The search identified 21 studies, including seven from Australia. There were 14 studies published since previous reviews. A series of robust, well-designed Australian studies demonstrate that reducing the hours during which on-premise alcohol outlets can sell alcohol late at night can substantially reduce rates of violence. The Australian studies are supported by a growing body of international research. CONCLUSION: The evidence of effectiveness is strong enough to consider restrictions on late trading hours for bars and hotels as a key approach to reducing late-night violence in Australia. PMID- 27714388 TI - Genetic feedback to reduce alcohol consumption in hospital outpatients with risky drinking: feasibility and acceptability. AB - OBJECTIVE: There have been no trials in healthcare settings of genetic susceptibility feedback in relation to alcohol consumption. The purpose of this study was to determine the feasibility and acceptability of conducting a full scale randomised trial estimating the effect of personalised genetic susceptibility feedback on alcohol consumption in hospital outpatients with risky drinking. METHODS: Outpatients >=18 years of age who reported drinking more than 14 standard drinks in the past week or in a typical week were asked to provide a saliva sample for genetic testing. Genetic susceptibility feedback was posted to participants 6 months after recruitment. The co-primary outcomes were the proportion of participants who (i) provided a saliva sample that could be genotyped, and (ii) spoke with a genetic counsellor. Secondary outcomes included changes in patients' weekly alcohol consumption; scores on scales measuring readiness to change, importance of changing and confidence in ability to change drinking habits; knowledge about which cancers are alcohol-attributable; and acceptability of the saliva collection procedure and the genetic-feedback intervention. McNemar's test and paired t-tests were used to test for differences between baseline and follow-up in proportions and means, respectively. RESULTS: Of 100 participants who provided a saliva sample, 93 had adequate DNA for at least one genotyping assay. Three participants spoke to a genetic counsellor. Patients' readiness to change their drinking, their views on the importance of changing and their stated confidence in their ability to change increased between baseline and follow-up. There was no increase in patients' knowledge about alcohol-attributable cancers nor any reduction in how much alcohol they drank 4 months after receiving the feedback. Most participants (80%) were somewhat comfortable or very comfortable with the process used to collect saliva, 84% understood the genetic feedback, 54% found it useful, 10% had sought support to reduce their drinking after receiving the feedback, and 37% reported that the feedback would affect how much they drink in the future. CONCLUSION: Results of this study suggest it would be feasible to conduct a methodologically robust trial estimating the effect of genetic susceptibility feedback on alcohol consumption in hospital outpatients with risky drinking. PMID- 27714389 TI - Mesothelioma trends in the ACT and comparisons with the rest of Australia. AB - OBJECTIVES: Inhalation of asbestos fibres is the predominant cause of malignant mesothelioma. Domestic exposure to asbestos is a major community concern in the Australian Capital Territory (ACT) because of loose-fill asbestos home insulation. Little is known about how trends in mesothelioma rates in the ACT compare with those elsewhere. The objective of this study was to describe trends in mesothelioma rates in the ACT and compare them with those for the rest of Australia. METHODS: We used de-identified data from the ACT Cancer Registry (1982 2014), and the Western Australia (WA) Cancer Registry and the Australian Cancer Database (1982-2011). We calculated crude mesothelioma rates, by 3-year periods, for the ACT and for the rest of Australia (excluding WA). We used Poisson regression to analyse mesothelioma trends from 1994 to 2011 (complete reporting period) using an indirect standardisation approach to adjust for age and sex. RESULTS: There were 140 mesothelioma cases reported to the ACT Cancer Registry between 1982 and 2014 - 81% male and 19% female. Between 1994 and 2011, age- and sex-adjusted mesothelioma rates in the ACT increased over time, on average by 12% per 3-year period (relative risk [RR] 1.12; 95% confidence interval [CI] 0.99, 1.26). Compared with the rest of Australia (excluding WA), ACT rates were, on average, lower (RR 0.84; 95% CI 0.69, 1.02), but they increased at a higher rate (RR 1.12 per 3-year period; 95% CI 0.99, 1.27). These results are strongly influenced by the higher rate of mesothelioma observed in the ACT in 2009-2011, when ACT rates became similar to those for the rest of Australia (excluding WA). CONCLUSIONS: Although mesothelioma rates may have increased more in the ACT than the rest of Australia (excluding WA) during the past two decades, there is considerable uncertainty in the trends. More information is needed regarding the health risks associated with living in a house with loose-fill asbestos insulation. This is the subject of further studies within the ACT Asbestos Health Study. PMID- 27714390 TI - Developing a new Get Healthy Service program on reducing risky alcohol consumption. AB - Risky alcohol use has significant individual health and social impacts, and is related to short- and long-term harm, including injuries, accidents, liver diseases, some cancers, cardiovascular diseases and alcohol dependence. The Get Healthy Information & Coaching Service (GHS) is a free telephone coaching service supporting adults 16 years or older to reduce weight, improve nutrition and increase physical activity. Tailored programs are available for Aboriginal people, pregnant women and people at risk of type 2 diabetes. The GHS provides an opportunity to implement a specific program for participants wishing to reduce or cease their alcohol consumption. This paper describes the processes used to develop an Alcohol Program for the GHS. It outlines the contributions from clinical and program experts, the evidence base for the program's development, clinical screening tools, training for health coaches and referral processes for participants. The Alcohol Program has the potential to provide effective coaching to adults to voluntarily reduce short- and long-term risky alcohol consumption. PMID- 27714391 TI - Development of a multiple risk factor Brief Health Check for workplaces. AB - Health promotion in workplace settings has been prioritised to reduce chronic disease risk factors, both in Australia and internationally. This paper describes the design of a health risk assessment tool, the Brief Health Check (BHC). The BHC is one of two components of Get Healthy at Work, a state government-funded health promotion program for New South Wales workplaces. Policy imperatives required scaled-up delivery in the absence of a full pre-implementation summative evaluation. Translational formative evaluation was adapted to design an evidence based health risk assessment tool, a process for referring workers to healthy lifestyle programs, and a process for general practitioners to help workers mitigate their risk of chronic disease, independently of the workplace. The tool had good feasibility and acceptance, but barriers included business organisational issues (including the time taken to facilitate the health checks) and some scepticism among workers about the motivation of businesses and the absence of measurements other than waist circumference. A cluster nonrandomised trial showed no benefit of a modest incentive for participation. A significant proportion of workers were identified as being at risk of chronic disease, and many received an appropriate referral to an evidence based program. More work to improve uptake of referrals will increase the public health impact of the BHC. PMID- 27714392 TI - Public health advocacy in action: the case of unproven breast cancer screening in Australia. AB - In recent years, nonmammographic breast imaging devices, such as thermography, electrical impedance scanning and elastography, have been promoted directly to consumers, which has captured the attention of governments, researchers and health organisations. These devices are not supported by evidence and risk undermining existing mammographic breast cancer screening services. During a 5 year period, Cancer Council Western Australia (CCWA) used strategic research combined with legal, policy and media advocacy to contest claims that these devices were proven alternatives to mammography for breast cancer screening. The campaign was successful because it had input from people with public health, academic, clinical and legal backgrounds, and took advantage of existing legal and regulatory avenues. CCWA's experience provides a useful advocacy model for public health practitioners who are concerned about unsafe consumer products, unproven medical devices, and misleading health information and advertising.

AB - OBJECTIVES: Raw accelerometry is increasingly being used in physical activity research, but diversity in sensor design, attachment and signal processing challenges the comparability of research results. Therefore, efforts are needed to harmonize the methodology. In this article we reflect on how increased methodological harmonization may be achieved. METHODS: The authors of this work convened for a two-day workshop (March 2014) themed on methodological harmonization of raw accelerometry. The discussions at the workshop were used as a basis for this review. RESULTS: Key stakeholders were identified as manufacturers, method developers, method users (application), publishers, and funders. To facilitate methodological harmonization in raw accelerometry the following action points were proposed: i) Manufacturers are encouraged to provide a detailed specification of their sensors, ii) Each fundamental step of algorithms for processing raw accelerometer data should be documented, and ideally also motivated, to facilitate interpretation and discussion, iii) Algorithm developers and method users should be open about uncertainties in the description of data and the uncertainty of the inference itself, iv) All new algorithms which are pitched as "ready for implementation" should be shared with the community to facilitate replication and ongoing evaluation by independent groups, and v) A dynamic interaction between method stakeholders should be encouraged to facilitate a well-informed harmonization process. CONCLUSIONS: The workshop led to the identification of a number of opportunities for harmonizing methodological practice. The discussion as well as the practical checklists proposed in this review should provide guidance for stakeholders on how to contribute to increased harmonization. PMID- 27714397 TI - Comparing Graphical Formats for Feedback of Clinical Practice Data. A Multicenter Study among Anesthesiologists in France. AB - OBJECTIVES: Although graphical formats used to feedback clinical practice data may have an important impact, the most effective formats remain unknown. Using prevention of postoperative nausea and vomiting by anesthesiologists as an application, the objective of this study was to assess which graphical formats for feedback of clinical practice data are the most incentive to change practice. METHODS: We conducted a multicenter cross-sectional study among anesthesiologists randomized in two groups between March and June 2014. Each anesthesiologist assessed 15 graphical formats displaying an indicator of either prescription conformity or prescription effectiveness. Graphical formats varied by: type of graph (bar charts, linear sliders, or pictographs), presence or not of a target to reach, presence or not of a contrast between a hypothetical physician and his / her team, direction of the difference between the physician and his / her team, and restitution or not of the quality indicator evolution over the previous six months. The primary outcome was a numerical scale score expressing the anesthesiologists' motivation to change his / her practice (ranging from 1 to 10 points). A linear mixed model was fitted to explain variation in motivation. RESULTS: Sixty-six anesthesiologists assessed the conformity indicator and 67 assessed the effectiveness indicator. Factors associated with an increased motivation to change practice were: (i) presence of a clearly defined target to reach (conformity: beta = 0.24 points, p = 0.0046; effectiveness: beta = 1.11 points, p < 0.0001); (ii) contrast between the physician and his / her team (conformity: beta = 0.38 points, p < 0.0001; effectiveness: beta = 0.33 points, p = 0.0021); (iii) better results for the team than for the physician (conformity: beta = 0.65 points, p < 0.0001; effectiveness beta = 1.16 points, p < 0.0001). For the effectiveness indicator, anesthesiologists were more motivated to change practice with bar charts (beta = 0.24 points, p = 0.0447) and pictographs (beta = 0.45 points, p = 0.0001) than with linear sliders. CONCLUSIONS: Graphs associated with a defined target to reach should be preferred to deliver feedback, especially bar graphs or pictographs for indicators which are more complex to represent such as effectiveness indicators. Anesthesiologists are also more motivated to change practice when graphs report contrasted data between the physician and his / her team and a lower conformity or effectiveness for the physician than for his / her team. PMID- 27714398 TI - Seasonal influenza in octogenarians and nonagenarians admitted to a general hospital: epidemiology, clinical presentation and prognostic factors. AB - OBJECTIVE: Seasonal influenza is responsible for high annual morbidity and mortality worldwide, especially in elderly patients. The aim of the study was to analyse the epidemiological, clinical and prognostic features of influenza in octogenarians and nonagenarians admitted to a general hospital, as well as risk factors associated with mortality. METHODS: Retrospective, cross-sectional, descriptive study in patients admitted and diagnosed with influenza by molecular biology in the General University Hospital of Alicante from 1 January to 31 April 2015. RESULTS: A total of 219 patients were diagnosed with influenza in the study period: 55 (25.1%) were <=64 years-old; 77 (35.2%) were aged 65-79; 67 (30.6%) were aged 80-89 years; and 20 (9.1%) were aged >=90 years. Most flu episodes were caused by influenza A (n=181, 82.6%). Patients aged 80 years or older had lower glomerular filtration rate (mean: 49.7 mL/min vs. 62.2 mL/min; p=0.006), a greater need for non-invasive mechanical ventilation (22% vs 9.3%; p=0.02), greater co-morbidity due to cardiac insufficiency (40.5% vs. 16.4%; p<0.001) and chronic renal disease (32.9 vs. 20%, p=0.03), and greater mortality (19% vs. 2.9%; p<0.001). In a multivariate analysis, mortality was higher in those aged 80 or over (adjusted odds ratio [ORa] 9.2, 95% confidence interval [CI] 1.65-51.1), those who had acquired the flu in a long-term care facility (ORa 11.9, 95% CI 1.06-134), and those with hyperlactataemia (ORa 1.89, 95% CI 1.20-3.00). CONCLUSIONS: Seasonal influenza is a serious problem leading to elevated mortality in octogenarian and nonagenarian patients admitted to a general hospital. PMID- 27714399 TI - [Demographic and clinical features of diagnosed individuals of enterobiasis in the southern Gran Canaria: sampling assessment]. AB - OBJECTIVE: Enterobius vermicularis, also known as pinworn, is the responsible agent for Human Enterobiasis. It is one of the most prevalent, but underrated, parasitic disease in children population. Diagnosis involves demonstration of either eggs or adult worms by Graham test. The aim of this study is to describe the clinical, demographic and microbiological features of patients with suspected diagnosis of Enterobiasis in southern Gran Canaria. METHODS: Descriptive and prospective study of perianal samples evaluated by Graham test in the Microbiology Department of 'Insular de Gran Canaria' University Hospital between November 2014 and November 2015. Descriptive analysis to evaluate the correlation between clinical and demographic variables and the results of Graham test microbiological observation. RESULTS: 1,128 samples were analyzed. E. vermicularis was found in 11.4% of the samples. Among the positives samples, 88.4% belonged to children under 14 years, and 53.5% were male. Abdominal pain (18.6%), anal itching (11.6%), eosinophilia (8.5%) and intestinal parasitosis suspicion (7.8%) were the reasons of parasitological investigation request in positive samples. Nevertheless, a high proportion of the requests was not founded in a suspicious diagnosis or was unrelated to Enterobiasis. CONCLUSIONS: Enterobiasis is a common disease in primary health care and is of great importance in Gran Canaria. Quality in sample collection as well as diagnosis suspicious information are necessary for a good microbiological analysis.

AB - Liquid chromatography-high resolution mass spectrometry (LC-HRMS) is a well established technique for nontarget screening of contaminants in complex environmental samples. Automatic peak detection is essential, but its performance has only rarely been assessed and optimized so far. With the aim to fill this gap, we used pristine water extracts spiked with 78 contaminants as a test case to evaluate and optimize chromatogram and spectral data processing. To assess whether data acquisition strategies have a significant impact on peak detection, three values of MS cycle time (CT) of an LTQ Orbitrap instrument were tested. Furthermore, the key parameter settings of the data processing software MZmine 2 were optimized to detect the maximum number of target peaks from the samples by the design of experiments (DoE) approach and compared to a manual evaluation. The results indicate that short CT significantly improves the quality of automatic peak detection, which means that full scan acquisition without additional MS2 experiments is suggested for nontarget screening. MZmine 2 detected 75-100 % of the peaks compared to manual peak detection at an intensity level of 105 in a validation dataset on both spiked and real water samples under optimal parameter settings. Finally, we provide an optimization workflow of MZmine 2 for LC-HRMS data processing that is applicable for environmental samples for nontarget screening. The results also show that the DoE approach is useful and effort saving for optimizing data processing parameters. Graphical Abstract ?. PMID- 27714403 TI - Responses of the Antioxidant and Osmoregulation Systems of Fish Erythrocyte Following Copper Exposures in Differing Calcium Levels. AB - Freshwater fish Oreochromis niloticus were exposed to Cu in differing Ca2+ levels (15, 30 and 90 mg/L), using acute (0.3 uM, 3 d) and chronic (0.03 uM, 30 d) exposure protocols and enzyme activities related to the antioxidant (catalase, CAT, EC 1.11.1.6; superoxide dismutase, SOD, EC 1.15.1.1; glutathione peroxidase, GPx, EC 1.11.1.9) and osmoregulation (Total, Na+/K+-ATPase, EC 3.6.3.9, Mg2+ ATPase, EC 3.6.3.2) systems in the erythrocytes were measured. Activities of antioxidant enzymes generally decreased significantly following either Ca2+ alone or Ca2++Cu combinations in both acute and chronic exposures. Na+/K+-ATPase activity significantly decreased in chronic exposures, though there was no clear trend in acute exposures. Mg2+-ATPase activity increased significantly in acute exposures, but not in chronic ones. There were more significant alterations in acute exposure compared to chronic ones. There was no clear trend regarding Cu toxicity and its relationship with Ca2+, which may possibly be prompted by the compensatory mechanisms of the enzymes. It may be concluded that freshwater fish erythrocytes may face different degrees of more physiological stress from different waters. PMID- 27714404 TI - The influence of motor imagery on the learning of a fine hand motor skill. AB - Motor imagery has been argued to affect the acquisition of motor skills. The present study examined the specificity of motor imagery on the learning of a fine hand motor skill by employing a modified discrete sequence production task: the Go/NoGo DSP task. After an informative cue, a response sequence had either to be executed, imagined, or withheld. To establish learning effects, the experiment was divided into a practice phase and a test phase. In the latter phase, we compared mean response times and accuracy during the execution of unfamiliar sequences, familiar imagined sequences, and familiar executed sequences. The electroencephalogram was measured in the practice phase to compare activity between motor imagery, motor execution, and a control condition in which responses should be withheld. Event-related potentials (ERPs) and event-related lateralizations (ERLs) showed strong similarities above cortical motor areas on trials requiring motor imagery and motor execution, while a major difference was found with trials on which the response sequence should be withheld. Behavioral results from the test phase showed that response times and accuracy improved after physical and mental practice relative to unfamiliar sequences (so-called sequence-specific learning effects), although the effect of motor learning by motor imagery was smaller than the effect of physical practice. These findings confirm that motor imagery also resembles motor execution in the case of a fine hand motor skill. PMID- 27714406 TI - You neglected a few.

PMID- 27714408 TI - Single cell biology beyond the era of antibodies: relevance, challenges, and promises in biomedical research. AB - Research of the past two decades has proved the relevance of single cell biology in basic research and translational medicine. Successful detection and isolation of specific subsets is the key to understand their functional heterogeneity. Antibodies are conventionally used for this purpose, but their relevance in certain contexts is limited. In this review, we discuss some of these contexts, posing bottle neck for different fields of biology including biomedical research. With the advancement of chemistry, several methods have been introduced to overcome these problems. Even though microfluidics and microraft array are newer techniques exploited for single cell biology, fluorescence-activated cell sorting (FACS) remains the gold standard technique for isolation of cells for many biomedical applications, like stem cell therapy. Here, we present a comprehensive and comparative account of some of the probes that are useful in FACS. Further, we illustrate how these techniques could be applied in biomedical research. It is postulated that intracellular molecular markers like nucleostemin (GNL3), alkaline phosphatase (ALPL) and HIRA can be used for improving the outcome of cardiac as well as bone regeneration. Another field that could utilize intracellular markers is diagnostics, and we propose the use of specific peptide nucleic acid probes (PNPs) against certain miRNAs for cancer surgical margin prediction. The newer techniques for single cell biology, based on intracellular molecules, will immensely enhance the repertoire of possible markers for the isolation of cell types useful in biomedical research.

AB - The oomycete Phytophthora infestans is the cause of late blight in potato and tomato. It is a devastating pathogen and there is an urgent need to design alternative strategies to control the disease. To find novel potential drug targets, we used Lifeact-eGFP expressing P. infestans for high resolution live cell imaging of the actin cytoskeleton in various developmental stages. Previously, we identified actin plaques as structures that are unique for oomycetes. Here we describe two additional novel actin configurations; one associated with plug deposition in germ tubes and the other with appressoria, infection structures formed prior to host cell penetration. Plugs are composed of cell wall material that is deposited in hyphae emerging from cysts to seal off the cytoplasm-depleted base after cytoplasm retraction towards the growing tip. Preceding plug formation there was a typical local actin accumulation and during plug deposition actin remained associated with the leading edge. In appressoria, formed either on an artificial surface or upon contact with plant cells, we observed a novel aster-like actin configuration that was localized at the contact point with the surface. Our findings strongly suggest a role for the actin cytoskeleton in plug formation and plant cell penetration. PMID- 27714410 TI - Role of CFTR in epithelial physiology. AB - Salt and fluid absorption and secretion are two processes that are fundamental to epithelial function and whole body fluid homeostasis, and as such are tightly regulated in epithelial tissues. The CFTR anion channel plays a major role in regulating both secretion and absorption in a diverse range of epithelial tissues, including the airways, the GI and reproductive tracts, sweat and salivary glands. It is not surprising then that defects in CFTR function are linked to disease, including life-threatening secretory diarrhoeas, such as cholera, as well as the inherited disease, cystic fibrosis (CF), one of the most common life-limiting genetic diseases in Caucasian populations. More recently, CFTR dysfunction has also been implicated in the pathogenesis of acute pancreatitis, chronic obstructive pulmonary disease (COPD), and the hyper responsiveness in asthma, underscoring its fundamental role in whole body health and disease. CFTR regulates many mechanisms in epithelial physiology, such as maintaining epithelial surface hydration and regulating luminal pH. Indeed, recent studies have identified luminal pH as an important arbiter of epithelial barrier function and innate defence, particularly in the airways and GI tract. In this chapter, we will illustrate the different operational roles of CFTR in epithelial function by describing its characteristics in three different tissues: the airways, the pancreas, and the sweat gland. PMID- 27714412 TI - Ecology and sampling techniques of an understudied subterranean habitat: the Milieu Souterrain Superficiel (MSS). AB - The term Milieu Souterrain Superficiel (MSS) has been used since the early 1980s in subterranean biology to categorize an array of different hypogean habitats. In general terms, a MSS habitat represents the underground network of empty air filled voids and cracks developing within multiple layers of rock fragments. Its origins can be diverse and is generally covered by topsoil. The MSS habitat is often connected both with the deep hypogean domain-caves and deep rock cracks-and the superficial soil horizon. A MSS is usually characterized by peculiar microclimatic conditions, and it can harbor specialized hypogean, endogean, and surface-dwelling species. In light of the many interpretations given by different authors, we reviewed 235 papers regarding the MSS in order to provide a state-of the-art description of these habitats and facilitate their study. We have briefly described the different types of MSS mentioned in the scientific literature (alluvial, bedrock, colluvial, volcanic, and other types) and synthesized the advances in the study of the physical and ecological factors affecting this habitat-i.e., microclimate, energy flows, animal communities, and trophic interactions. We finally described and reviewed the available sampling methods used to investigate MSS fauna. PMID- 27714411 TI - How cardiomyocytes sense pathophysiological stresses for cardiac remodeling. AB - In the past decades, the cardiovascular community has laid out the fundamental signaling cascades that become awry in the cardiomyocyte during the process of pathologic cardiac remodeling. These pathways are initiated at the cell membrane and work their way to the nucleus to mediate gene expression. Complexity is multiplied as the cardiomyocyte is subjected to cross talk with other cells as well as a barrage of extracellular stimuli and mechanical stresses. In this review, we summarize the signaling cascades that play key roles in cardiac function and then we proceed to describe emerging concepts of how the cardiomyocyte senses the mechanical and environmental stimuli to transition to the deleterious genetic program that defines pathologic cardiac remodeling. As a highlighting example of these processes, we illustrate the transition from a compensated hypertrophied myocardium to a decompensated failing myocardium, which is clinically manifested as decompensated heart failure.

PMID- 27714414 TI - [Long-term outcome after endoscopic enucleation of the prostate : From monopolar enucleation to HoLEP and from HoLEP to EEP]. AB - BACKGROUND: In the last 20 years various transurethral endoscopic enucleation techniques (EEP) have been established as a substitute for open prostatectomy (OP) and TURP. Since the 2016 update of the "EAU Guidelines on Management of Non Neurogenic Male Lower Urinary Tract Symptoms (LUTS), including Benign Prostatic Obstruction (BPO)", Holmium laser enucleation of the prostate (HoLEP) and bipolar enucleation being summarized as anatomical enucleating techniques are proposed as first choice for the surgical management of BPO of large volume prostates. OBJECTIVES: The purpose of this review is to demonstrate the available data on long-term outcomes of current EEP techniques. MATERIALS AND METHODS: PubMed/Medline and Scopus were searched using the terms: long term, HoLEP, ThuLEP, ThuVEP, DiLEP, ELEP, GreenlEP, Greenlight enucleation, bipolar enucleation, plasmakinetic enucleation, monopolar enucleation, and transurethral enucleation. Studies with a follow-up >=48 months were selected. RESULTS: In all, 5 randomized controlled trials (2 HoLEP, 2 bipolar enucleation, 1 Thulium laser resection of the prostate in tangerine technique [TmLR-TT]), 3 prospective cohort studies (2 thulium vapoenucleation [ThuVEP], 1 TmLRP-TT), and 2 retrospective studies with large patient cohorts were selected. All EEP were equivalent to OP with regard to effectivity and durability of results. The rate of secondary surgical procedures in HolEP, ThuVEP, bipolar enucleation and tangerine technique (TmLRP-TT) was 0-1.2 % for reTURP, 1.9-3.75 % for urethrotomy, and 0.9-4 % for bladder neck resection. No significant difference in the individual studies was found when compared to OP. For bipolar enucleation vs. TURP long-term results for uroflow, residual urine, and IPSS were significantly better at 60 months for bipolar enucleation. One RCT TmLRP-TT vs. TURP at the 48-month follow-up found no significant difference. CONCLUSION: Various transurethral EEP can be considered as equally safe and effective anatomical enucleation techniques. All displayed EEPs match the durability of OP. The choice of energy source for EEP seems to be secondary and a function of resources and personal preference of the skilled surgeon.

PMID- 27714415 TI - Intravertebral cleft in pathological vertebral collapse resulting from cancer metastasis: report of three cases. AB - Intravertebral cleft (IVC) is a common finding in osteoporotic compression fracture. However, since the vertebral collapse attributable to cancer metastasis is rarely associated with IVC, the phenomenon is generally considered as a sign of a benign lesion. In this study, we retrospectively reviewed the radiographs, computed tomography scans, and magnetic resonance images of 111 patients with spinal metastasis. Three cases (2.7 %) had IVC in the collapsed thoracic vertebral bodies (T7, T8, and T11) attributable to cancer metastasis. IVC alone is not necessarily an indicator of a benign vertebral collapse. PMID- 27714417 TI - QTL mapping for downy mildew resistance in cucumber via bulked segregant analysis using next-generation sequencing and conventional methods. AB - KEY MESSAGE: QTL mapping using NGS-assisted BSA was successfully applied to an F 2 population for downy mildew resistance in cucumber. QTLs detected by NGS assisted BSA were confirmed by conventional QTL analysis. Downy mildew (DM), caused by Pseudoperonospora cubensis, is one of the most destructive foliar diseases in cucumber. QTL mapping is a fundamental approach for understanding the genetic inheritance of DM resistance in cucumber. Recently, many studies have reported that a combination of bulked segregant analysis (BSA) and next generation sequencing (NGS) can be a rapid and cost-effective way of mapping QTLs. In this study, we applied NGS-assisted BSA to QTL mapping of DM resistance in cucumber and confirmed the results by conventional QTL analysis. By sequencing two DNA pools each consisting of ten individuals showing high resistance and susceptibility to DM from a F2 population, we identified single nucleotide polymorphisms (SNPs) between the two pools. We employed a statistical method for QTL mapping based on these SNPs. Five QTLs, dm2.2, dm4.1, dm5.1, dm5.2, and dm6.1, were detected and dm2.2 showed the largest effect on DM resistance. Conventional QTL analysis using the F2 confirmed dm2.2 (R 2 = 10.8-24 %) and dm5.2 (R 2 = 14-27.2 %) as major QTLs and dm4.1 (R 2 = 8 %) as two minor QTLs, but could not detect dm5.1 and dm6.1. A new QTL on chromosome 2, dm2.1 (R 2 = 28.2 %) was detected by the conventional QTL method using an F3 population. This study demonstrated the effectiveness of NGS-assisted BSA for mapping QTLs conferring DM resistance in cucumber and revealed the unique genetic inheritance of DM resistance in this population through two distinct major QTLs on chromosome 2 that mainly harbor DM resistance.

AB - AIM: Serum total bilirubin (STB), a protective cardiovascular factor, was retrospectively investigated to determine the relationship between STB levels and the severity of disease in Chinese patients with stable coronary artery disease (CAD). PATIENTS AND METHODS: A total of 347 eligible patients presenting to our department from December 2007 to December 2012 were divided into tertiles according to their Syntax scores (low, moderate, and high). To clarify the association between STB levels and major adverse cardiovascular events (MACE), all patients were divided into two groups according to the median baseline STB (greater than or less than 13.2 MUmol/l), which was measured after at least 12-h fast. All participants were followed for a mean of 37.1 months for MACE, including all-cause death, recurrent nonfatal myocardial infarction, and recurrent percutaneous coronary intervention. RESULTS: The STB levels were significantly lower in the high Syntax score group than those of the other groups and were negatively correlated with the Syntax score and number of diseased vessels. Follow-up data showed a higher incidence of MACE in the low STB group compared with the high STB group. Elevated STB levels predict the long-term prognosis of patients with stable angina pectoris. Finally, Kaplan-Meier analysis showed a significantly higher event-free survival rate in the patients with high STB levels than those in the low STB group. CONCLUSIONS: STB levels were independently associated with the severity of disease in patients with stable CAD. Elevated STB is associated with cardiovascular events and may be useful as a biomarker of the severity and prognosis of stable CAD. PMID- 27714421 TI - Predictive ability of maximal tumor diameter on MRI for high-risk endometrial cancer. AB - AIM: To investigate the predictive ability of tumor size for deep myometrial invasion (>=50%) and metastatic lymphadenopathy, on maximal tumor diameter (MRI) of endometrial cancer. MATERIALS AND METHODS: Our study population consisted of 105 patients (mean age: 59.8 years) with histologically confirmed endometrial cancer. All patients underwent preoperative pelvic MRI. Tumor maximal diameter (size) was calculated on multiple sequences, and the largest value was recorded. Logistic regression analysis was performed to investigate the association of maximal tumor diameter (MRI) with the depth of myometrial invasion and the presence of pelvic nodal metastases (histology); optimal tumor size cut-off for the prediction of deep myometrial involvement and nodal metastases was calculated using ROC analysis. Surgicopathological specimen examination was the standard of reference. RESULTS: Tumor size on MRI, independently predicted deep myometrial invasion. Optimal maximal tumor diameter cut-off for the prediction of deep myometrial invasion was 2 cm (SE 90%, SP 50.9%). When tumor size was used as a categorical variable in the multiple logistic regression model, tumor size >2 cm had 10.04 times greater odds of deep myometrial invasion (95% CI 3.34-30.17, p < 0.001). Optimal tumor size cut-off for prediction of nodal metastases was 4 cm (SE 60%, SP 76.9%). Multiple logistic regression analysis with nodal metastases as a dependent variable showed that tumor size >4 cm had 4.79 times greater odds for malignant dissemination to the lymph nodes (95% CI 1.00-23.09, p = 0.047). CONCLUSION: Maximal tumor diameter on preoperative MRI may be yet another prognosticator for deep myometrial invasion and metastatic lymphadenopathy in patients with endometrial carcinoma. PMID- 27714420 TI - 3D T2-weighted and Gd-EOB-DTPA-enhanced 3D T1-weighted MR cholangiography for evaluation of biliary anatomy in living liver donors. AB - PURPOSE: To investigate whether the addition of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced 3D T1-weighted MR cholangiography (T1w-MRC) to 3D T2-weighted MRC (T2w-MRC) improves the confidence and diagnostic accuracy of biliary anatomy in living liver donors. METHODS: Two abdominal radiologists retrospectively and independently reviewed pre-operative MR studies in 58 consecutive living liver donors. The second-order bile duct visualization on T1w- and T2w-MRC images was rated on a 4-point scale. The readers also independently recorded the biliary anatomy and their diagnostic confidence using (1) combined T1w- and T2w-MRC, and (2) T2w-MRC. In the 23 right lobe donors, the biliary anatomy at imaging and the imaging-predicted number of duct orifices at surgery were compared to intra-operative findings. RESULTS: T1w MRC had a higher proportion of excellent visualization than T2w-MRC, 66% vs. 45% for reader 1 and 60% vs. 31% for reader 2. The median confidence score for biliary anatomy diagnosis was significantly higher with combined T1w- and T2w-MRC than T2w-MRC alone for both readers (Reader 1: 3 vs. 2, p < 0.001; Reader 2: 3 vs. 1, p < 0.001). Compared to intra-operative findings, the accuracy of imaging predicted number of duct orifices using combined T1w-and T2w-MRC was significantly higher than that using T2w-MRC alone (p = 0.034 for reader 1, p = 0.0082 for reader 2). CONCLUSION: The addition of Gd-EOB-DTPA-enhanced 3D T1w-MRC to 3D T2w-MRC improves second-order bile duct visualization and increases the confidence in biliary anatomy diagnosis and the accuracy in the imaging-predicted number of duct orifices acquired during right lobe harvesting.

PMID- 27714425 TI - Acting with the future in mind is impaired in long-term opiate users. AB - RATIONALE: Episodic foresight is a fundamental human capacity. It refers to the ability to simulate future situations and organise current actions accordingly. While there is some evidence that opiate users have a reduced capacity to imagine themselves in future situations, no study to date has assessed whether opiate users show deficits in the ability to take steps in the present in anticipation of future needs. OBJECTIVE: In this study, we assessed whether this functional aspect of episodic foresight is impaired in chronic opiate users and the extent to which any deficits are associated with executive dysfunction. METHODS AND RESULTS: Participants were 33 long-term opiate users enrolled in an opiate substitution program and 34 controls. Relative to controls, the opiate users displayed significant impairment (medium effect size eta 2p = 0.08) in the two behavioural measures of episodic foresight used (items acquired and items used in the VW Foresight task). Furthermore, executive functioning was associated with foresight ability, although this was restricted to items acquired, and the associations were generally stronger for the control group. CONCLUSIONS: These data provide important evidence suggesting that the functional aspect of episodic foresight is disrupted in long-term opiate users. While these deficits appear to have some links to impaired executive control, additional work is needed to gain a more complete understanding of the underlying cognitive and neural mechanisms involved. This, in turn, will have important implications for tailoring interventions with opiate users to maximise the likelihood of successful independent functioning. PMID- 27714423 TI - Scientific principles for the identification of endocrine-disrupting chemicals: a consensus statement. AB - Endocrine disruption is a specific form of toxicity, where natural and/or anthropogenic chemicals, known as "endocrine disruptors" (EDs), trigger adverse health effects by disrupting the endogenous hormone system. There is need to harmonize guidance on the regulation of EDs, but this has been hampered by what appeared as a lack of consensus among scientists. This publication provides summary information about a consensus reached by a group of world-leading scientists that can serve as the basis for the development of ED criteria in relevant EU legislation. Twenty-three international scientists from different disciplines discussed principles and open questions on ED identification as outlined in a draft consensus paper at an expert meeting hosted by the German Federal Institute for Risk Assessment (BfR) in Berlin, Germany on 11-12 April 2016. Participants reached a consensus regarding scientific principles for the identification of EDs. The paper discusses the consensus reached on background, definition of an ED and related concepts, sources of uncertainty, scientific principles important for ED identification, and research needs. It highlights the difficulty in retrospectively reconstructing ED exposure, insufficient range of validated test systems for EDs, and some issues impacting on the evaluation of the risk from EDs, such as non-monotonic dose-response and thresholds, modes of action, and exposure assessment. This report provides the consensus statement on EDs agreed among all participating scientists. The meeting facilitated a productive debate and reduced a number of differences in views. It is expected that the consensus reached will serve as an important basis for the development of regulatory ED criteria. PMID- 27714430 TI - Factors associated with the accuracy of self-reported osteoporosis in the community. AB - We examined the agreement between self-reported osteoporosis and bone mineral density (BMD) results through dual-energy x-ray absorptiometry (DXA) using data from a national representative sample taken from the US communities. Six-year data from the continuous National Health and Nutrition Examination Survey 2005 2006, 2007-2008, and 2009-2010 were merged. Participants included adults 50 years of age or older whose data appeared in both questionnaire and medical examination data files. Self-reported osteoporosis was defined by an affirmative response to a question in the osteoporosis questionnaire then compared with BMD-defined osteoporosis, defined by BMD values taken from the examination data. Agreement between self-reported osteoporosis and DXA results were low. Kappa was only 0.24 (95 % confidence interval = 0.21-0.27), and sensitivity and positive predictive value were 28.0 and 40.8 %, respectively. When stratified by gender or age group, agreement remained poor. Self-report of osteoporosis would not be suitable for accurate prevalence estimates for osteoporosis regardless of gender or age group. PMID- 27714428 TI - Pioglitazone attenuates the opioid withdrawal and vulnerability to relapse to heroin seeking in rodents. AB - RATIONALE: Relapse to opioids is often driven by the avoidance of the aversive states of opioid withdrawal. We recently demonstrated that activation of peroxisome proliferator-activated receptor gamma (PPARgamma) by pioglitazone reduces the motivation for heroin and attenuates its rewarding properties. However, the role of PPARgamma in withdrawal and other forms of relapse to heroin is unknown. OBJECTIVES: To further address this issue, we investigated the role of PPARgamma on the development and expression of morphine withdrawal in mice and the effect of pioglitazone on several forms of heroin relapse in rats. METHODS: We induced physical dependence to morphine in mice by injecting morphine twice daily for 6 days. Withdrawal syndrome was precipitated on day 6 with an injection of naloxone. In addition, different groups of rats were trained to self administer heroin and, after the extinction, the relapse was elicited by cues, priming, or stress. The effect of different doses of pioglitazone was tested on these different paradigms. RESULTS: Data show that chronic and acute administration of pioglitazone attenuates morphine withdrawal symptoms, and these effects are mediated by activation of PPARgamma receptors. Activation of PPARgamma by pioglitazone also abolishes yohimbine-induced reinstatement of heroin seeking and reduces heroin-induced reinstatement, while it does not affect cue-induced relapse. CONCLUSIONS: These findings provide new insights on the role of PPARgamma on opioid dependence and suggest that pioglitazone may be useful for the treatment of opioid withdrawal in opioid-addicted individuals. PMID- 27714429 TI - Alterations of consciousness and mystical-type experiences after acute LSD in humans. AB - RATIONALE: Lysergic acid diethylamide (LSD) is used recreationally and in clinical research. Acute mystical-type experiences that are acutely induced by hallucinogens are thought to contribute to their potential therapeutic effects. However, no data have been reported on LSD-induced mystical experiences and their relationship to alterations of consciousness. Additionally, LSD dose- and concentration-response functions with regard to alterations of consciousness are lacking. METHODS: We conducted two placebo-controlled, double-blind, cross-over studies using oral administration of 100 and 200 MUg LSD in 24 and 16 subjects, respectively. Acute effects of LSD were assessed using the 5 Dimensions of Altered States of Consciousness (5D-ASC) scale after both doses and the Mystical Experience Questionnaire (MEQ) after 200 MUg. RESULTS: On the MEQ, 200 MUg LSD induced mystical experiences that were comparable to those in patients who underwent LSD-assisted psychotherapy but were fewer than those reported for psilocybin in healthy subjects or patients. On the 5D-ASC scale, LSD produced higher ratings of blissful state, insightfulness, and changed meaning of percepts after 200 MUg compared with 100 MUg. Plasma levels of LSD were not positively correlated with its effects, with the exception of ego dissolution at 100 MUg. CONCLUSIONS: Mystical-type experiences were infrequent after LSD, possibly because of the set and setting used in the present study. LSD may produce greater or different alterations of consciousness at 200 MUg (i.e., a dose that is currently used in psychotherapy in Switzerland) compared with 100 MUg (i.e., a dose used in imaging studies). Ego dissolution may reflect plasma levels of LSD, whereas more robustly induced effects of LSD may not result in such associations. PMID- 27714432 TI - Abrupt transitions to tumor extinction: a phenotypic quasispecies model. AB - The dynamics of heterogeneous tumor cell populations competing with healthy cells is an important topic in cancer research with deep implications in biomedicine. Multitude of theoretical and computational models have addressed this issue, especially focusing on the nature of the transitions governing tumor clearance as some relevant model parameters are tuned. In this contribution, we analyze a mathematical model of unstable tumor progression using the quasispecies framework. Our aim is to define a minimal model incorporating the dynamics of competition between healthy cells and a heterogeneous population of cancer cell phenotypes involving changes in replication-related genes (i.e., proto-oncogenes and tumor suppressor genes), in genes responsible for genomic stability, and in house-keeping genes. Such mutations or loss of genes result into different phenotypes with increased proliferation rates and/or increased genomic instabilities. Despite bifurcations in the classical deterministic quasispecies model are typically given by smooth, continuous shifts (i.e., transcritical bifurcations), we here identify a novel type of bifurcation causing an abrupt transition to tumor extinction. Such a bifurcation, named as trans-heteroclinic, is characterized by the exchange of stability between two distant fixed points (that do not collide) involving tumor persistence and tumor clearance. The increase of mutation and/or the decrease of the replication rate of tumor cells involves this catastrophic shift of tumor cell populations. The transient times near bifurcation thresholds are also characterized, showing a power law dependence of exponent [Formula: see text] of the transients as mutation is changed near the bifurcation value. These results are discussed in the context of targeted cancer therapy as a possible therapeutic strategy to force a catastrophic shift by simultaneously delivering mutagenic and cytotoxic drugs inside tumor cells. PMID- 27714427 TI - Response to varying the nicotine content of cigarettes in vulnerable populations: an initial experimental examination of acute effects. AB - RATIONALE: The purpose of this study was to begin researching the effects of very low nicotine content cigarettes in smokers especially vulnerable to dependence to assess their potential as a less dependence-producing alternative to current commercial cigarettes. METHODS: Participants were 26 adult, daily cigarette smokers from one of three populations: economically disadvantaged women of reproductive age (n = 9), opioid-dependent individuals (n = 11), and individuals with affective disorders (n = 6). Participants completed fourteen 2-4-h experimental sessions in a within-subjects research design. Sessions were conducted following brief smoking abstinence. Four research cigarettes varying in nicotine content (0.4, 2.4, 5.2, and 15.8 mg/g) were studied under double-blind conditions, assessing smoking topography, subjective effects, and relative reinforcing effects of varying doses in concurrent choice tests. Results were collapsed across vulnerable populations and analyzed using repeated measures ANOVA. RESULTS: No significant differences between doses were discernible in smoking topography. All doses were equi-effective at reducing nicotine withdrawal. Ratings of satisfaction from smoking were lower at the 0.4 compared to 15.8 mg/g dose. Participants preferred the 15.8 mg/g dose over the 0.4 and 2.4 but not the 5.2 mg/g doses in concurrent choice testing; no differences between the two lowest doses were noted. CONCLUSIONS: All cigarettes effectively reduced nicotine withdrawal with no differences in smoking topography, suggesting minimal compensatory smoking. Dependence potential was lowest at the 0.4 mg/g dose. These initial results are promising regarding the feasibility of lowering nicotine content in cigarettes to very low levels in vulnerable populations without untoward effects. PMID- 27714431 TI - Augmentative biocontrol when natural enemies are subject to Allee effects. AB - Intraspecific interactions such as Allee effects are key properties that can guide population management. This contribution considers component Allee effects that are elementary mechanisms leading to declines of fitness at the population scale, i.e. demographic Allee effects. It especially focuses on the consequences of such properties in predator populations, and investigates their repercussions in a biological control context. A modelling framework able to account for reproductive and/or foraging component Allee effects is proposed. From this, four models of augmentative biological control, corresponding to the periodic introduction of natural enemies, have been investigated. This is done using semi discrete models: ordinary differential equations are used to depict predator-prey dynamics and a discrete equation describes the abrupt augmentation of predators at periodic intervals. In that context, stability of a prey-free solution corresponding to pest eradication has been analyzed. It has been found that rare but large introductions should be preferred over frequent and small ones, when Allee effects influence predator populations. In particular, the occurrence of foraging, rather than reproducing, Allee effects significantly hinders pest eradication. Cases where the pest-free solution is locally, but not globally, stable were also observed and were shown to be favored by the occurrence of reproductive Allee effects among predators. PMID- 27714426 TI - Chronic administration of the dopamine D2/3 agonist ropinirole invigorates performance of a rodent slot machine task, potentially indicative of less distractible or compulsive-like gambling behaviour. AB - RATIONALE: Whilst dopamine agonist therapies can successfully manage the symptoms of diseases such as Parkinson's disease (PD), fibromyalgia and restless leg syndrome, they can also cause impulse control and addiction disorders such as gambling disorder (GD). These compulsive behaviours seriously undermine the utility of such treatments. OBJECTIVES: The objective of the study was to model this phenomenon using a rodent slot machine task (rSMT) in order to investigate the neurobiological basis underlying such behavioural changes. METHODS: Male Long Evans rats were trained to perform the rSMT. The D2-like agonist ropinirole, or saline, was then delivered continuously for 28 days via osmotic mini-pump. The effects of ropinirole on baseline rSMT performance, as well as extinction and reinstatement sessions, were determined during this time. Brain samples from key frontostriatal regions implicated in GD and PD were then harvested immediately or after a 4-week washout period during which behaviour returned to pre-drug baseline. RESULTS: Ropinirole invigorated task performance, in that drug treatment resulted in a robust and sustained increase in the number of trials completed. Ex vivo analyses revealed that chronic ropinirole treatment led to a pattern of changes indicative of upregulation within the beta-arrestin-AKT GSK3beta intracellular cascade, recently theorised to dominate D2-mediated signalling under hyperdopaminergic conditions, in the dorsal striatum, rather than the canonical PKA-dependent signalling pathway associated with D2 receptor activation. CONCLUSIONS: Such findings provide novel insight into the role of dopamine signalling in mediating compulsive-like gambling behaviour and may inform more directed pharmacotherapies for the treatment of both idiopathic and iatrogenic GD. PMID- 27714435 TI - Transobturator versus single incision slings: 1-year results of a randomized controlled trial. AB - INTRODUCTION AND HYPOTHESIS: To compare 1-year surgical outcomes following transobturator (TO) sling placement and single incision (SI) sling placement for the treatment of stress urinary incontinence (SUI). METHODS: We performed a randomized trial at a single institution. Patients with urodynamically proven SUI were offered participation and randomized to placement of a TO sling (MonarcTM) or a SI sling (MiniArcTM) between 2008 and 2011. The primary outcome measure was urinary leakage during standardized cough stress test (CST). Forty subjects in each group were required to achieve 80 % power to detect an effect size of 0.25. RESULTS: A total of 98 patients were randomized with 49 patients in the TO group and 49 patients in the SI group. Preoperative demographics were similar between the groups (Table 1). The TO group had a significantly longer sling operative time (10.7 +/- 4.8 min vs. 7.8 +/- 4.9 min, p < 0.001) and greater estimated blood loss (31.6 +/- 26.6 mL vs. 22.9 +/- 22.1 mL, p = 0.02). At the 1-year follow-up, there was no difference in the primary outcome with 9 TO patients (21 %) and 12 SI patients (29 %) having a positive CST (p = 0.5). A composite measurement of 'failure', defined as patient-reported SUI and a positive CST, showed no difference between the TO group (17 %) and the SI group (27 %; p = 0.3). CONCLUSIONS: The SI sling provides comparable objective efficacy to the TO sling at 1 year.

AB - The most important goals for the field of immuno-oncology are to improve the response rate and increase the number of tumor indications that respond to immunotherapy, without increasing adverse side effects. One approach to achieve these goals is to use tumor-directed immunotherapy, i.e., to focus the immune activation to the most relevant part of the immune system. This may improve anti tumor efficacy as well as reduce immune-related adverse events. Tumor-directed immune activation can be achieved by local injections of immune modulators in the tumor area or by directing the immune modulator to the tumor using bispecific antibodies. In this review, we focus on therapies targeting checkpoint inhibitors and co-stimulatory receptors that can generate tumor-specific T cell responses through localized immune activation. PMID- 27714437 TI - Dynamic knee behaviour: does the knee deformity change as it is flexed-an assessment and classification with computer navigation. AB - PURPOSE: The aim of this study was to assess the kinematics of arthritic knees prior to TKA. The hypothesis was that the arthritic knee follows distinct patterns with regard to deformity in coronal plane as it flexes from extended position. METHOD: Data from 585 consecutive arthritic knees that had undergone TKA using two non-image-based navigation systems were included in the study. Coronal plane alignment given by the femoro-tibial mechanical angle (FTMA) was recorded in extension, 30 degrees , 60 degrees , 90 degrees and maximum flexion prior to making any bony cuts or ligamentous releases. RESULTS: Complete data were available for 512 (87.5 %) of arthritic knees. It was found that pre-implant arthritic knees behaved in different distinct patterns from full extension to 90 degrees flexion. These patterns in FTMA from extension through to 90 degrees of flexion were classified into 4 major types (1, 2, 3, and 4) and 8 subgroups (1A, 1B, 2A, 2B, 3, 4A, 4B, 4C) for varus and valgus knees. Beyond 90 degrees of flexion, there were no distinct or consistent patterns. There were differences between varus and valgus knee deformities not only in overall numbers (73.8 % varus vs. 21.1 % valgus) but also in kinematic behaviour. Only 14.1 % of total knees had a consistent deformity (Type 1A) which remained the same throughout the range of flexion. 14.1 % knees actually become opposite deformity as the knee flexes; thus, varus becomes valgus and valgus becomes varus as the knee flexes (Type 3 and 4C). CONCLUSION: This study has observed and categorised distinct patterns which arthritic knees follow in the coronal plane as it flexes. This dynamic change during flexion will have bearing on collateral releases that are traditionally done based on deformity in extension or 90 degrees flexion mainly. This may be the underlying cause of flexion instability especially for Types 3 and 4C knees if collateral soft tissue release is done based on deformity in extension. Full significance of this remains unknown and will need further investigation. LEVEL OF EVIDENCE: III. PMID- 27714434 TI - Contemporary experience with high-dose interleukin-2 therapy and impact on survival in patients with metastatic melanoma and metastatic renal cell carcinoma. AB - High-dose interleukin-2 (HD IL-2) was approved for treatment of metastatic renal cell carcinoma (mRCC) in 1992 and for metastatic melanoma (mM) in 1998, in an era predating targeted therapies and immune checkpoint inhibitors. The PROCLAIMSM registry was established to collect and analyze data for patients treated with HD IL-2 in the current era. This analysis includes 170 patients with mM and 192 patients with mRCC treated between 2005 and 2012 with survival data current as of July 27, 2015. For patients with mM, complete response (CR) was observed in 5 %, partial response (PR) in 10 %, stable disease (SD) in 22 %, and 63 % had progressive disease (PD). The median overall survival (mOS) for these patients was 19.6 months, with a median follow-up of 43.1 months. The mOS was not reached for patients achieving CR or PR, and was 33.4 months for patients with SD. For patients with mRCC, 6 % achieved CR, 9 % had PR, 22 % had SD, and 62 % had PD. The mOS was 41 months, with a median follow-up of 46.6 months. The mOS for patients who had CR and PR was not reached and was 49.6 months for patients with SD. There were no treatment-related deaths among 362 patients. The duration of mOS for patients with mM and mRCC is longer than historically reported. These data support a continued role for IL-2 in the treatment of eligible patients with mM or mRCC and warrant further evaluation of HD IL-2 in combination or sequence with other therapeutic agents. PMID- 27714439 TI - The Cumberland Ankle Instability Tool (CAIT) in the Dutch population with and without complaints of ankle instability. AB - PURPOSE: To develop a translated Dutch version of the Cumberland Ankle Instability Tool (CAIT) and test its psychometric properties in a Dutch population with foot and ankle complaints. METHODS: The CAIT was translated into the Dutch language using a forward-backward translation design. Of the 130 subsequent patients visiting the outpatient clinic for foot and ankle complaints who were asked to fill out a questionnaire containing the CAIT, the Foot and Ankle Outcome Score (FAOS), and the numeric rating scale (NRS) pain, 98 completed the questionnaire. After a 1-week period, patients were asked to fill out a second questionnaire online containing the CAIT and NRS pain. This second questionnaire was completed by 70 patients. With these data, the construct validity, test-retest reliability, internal consistency, measurement error, and ceiling and floor effects were assessed. Additionally, a cut-off value to discriminate between stable and unstable ankles, in patients with ankle complaints, was calculated. RESULTS: Construct validity showed moderate correlations between the CAIT and FAOS subscales (Spearman's correlation coefficient (SCC) = 0.36-0.43), and the NRS pain (SCC = -0.55). The cut-off value was found at 11.5 points of the total CAIT score (range 0-30). Test-retest reliability showed to be excellent with an intraclass correlation coefficient of 0.94. Internal consistency was high (Cronbach's alpha = 0.86). No ceiling or floor effects were detected. CONCLUSION: Based on the results, the Dutch version of the CAIT is a valid and reliable questionnaire to assess ankle instability in the Dutch population and is able to differentiate between a functionally unstable and stable ankle. The tool is the first suitable tool to objectify the severity of ankle instability specific complaints and assess change in the Dutch population. Level of evidence II. PMID- 27714438 TI - High mid-term revision rate after treatment of large, full-thickness cartilage lesions and OA in the patellofemoral joint using a large inlay resurfacing prosthesis: HemiCAP-Wave(r). AB - PURPOSE: The HemiCAP-Wave(r) implant for the patellofemoral resurfacing treatment of large cartilage lesions and osteoarthritis (OA) was introduced in 2009. The outcome of a prospective cohort study of 18 patients with large trochlea lesions or isolated OA treated with the HemiCAP-Wave(r) implant is presented with up to a 6-year survival rate, and hypothesised short-to mid-term reduced pain and improved function. METHODS: Indication for treatment with the HemiCAP-Wave(r) implant was a symptomatic, large cartilage lesion in trochlea demonstrated by MRI or arthroscopy, which was ICRS grades 3-4 and larger than 4 cm2. Patients were followed for 2 years with American Knee Society Subjective outcome Scores (AKSS), pain scores and radiographic evaluations and for up to 6 years with complications and reoperations. RESULTS: At the 1- and 2-year follow-up mean AKSS clinical score, the mean AKSS function score and mean pain score improved significantly. Within 6 years, 28 % of the implants were revised to arthroplasty due to the progression of cartilage lesions, osteoarthritis or increased knee pain. CONCLUSION: The present study demonstrated an improved short- to mid-term clinical outcome and reduced pain but high mid-term revision rate after patellofemoral inlay resurfacing using the HemiCAP-Wave(r) implant. Patellofemoral resurfacing implantation treatment with a large inlay prosthesis can offer temporary treatment for large isolated patellofemoral cartilage lesions or OA in younger patients with almost healthy cartilage in the other compartments who are not yet eligible for arthroplasty treatment. LEVEL OF EVIDENCE: IV. PMID- 27714436 TI - Suprapubic versus transurethral bladder drainage following reconstructive pelvic surgery: a comparison of patient satisfaction and quality of life. AB - INTRODUCTION AND HYPOTHESIS: To assess the differences in patient-reported, catheter-specific satisfaction and quality of life with either suprapubic or transurethral postoperative bladder drainage following reconstructive pelvic surgery. METHODS: This was a prospective study of all eligible women who were scheduled to undergo reconstructive surgery requiring bladder drainage during the study period November 2013 to March 2015. Women who did not undergo the planned procedure(s) or did not require bladder drainage were excluded. The primary outcome was patient-reported quality of life using catheter-specific instruments including the Catheter-related Quality of Life (CIQOL) instrument, and a modified version of the Intermittent Self-Catheterization Questionnaire (ISC-Q), designed to evaluate aspects of catheter-related quality of life and satisfaction specific to the needs of the individual. RESULTS: A total of 178 women were analyzed, 108 in the transurethral catheter group and 70 in the suprapubic group. Women with suprapubic bladder drainage had higher quality of life and satisfaction scores than women with transurethral bladder drainage as measured by the ISC-Q (68.31 +/ 16.87 vs. 54.04 +/- 16.95, mean difference 14.27, 95 % CI 9.15 - 19.39). There was no difference in quality of life by the CIQOL. After regression analysis, women with suprapubic bladder drainage were more satisfied with their catheter specific needs despite longer duration of catheter use, more concurrent continence surgery, and higher trait anxiety. CONCLUSIONS: Differences in catheter-specific quality of life and patient satisfaction scores favoring suprapubic bladder drainage support its continued use in appropriately selected women for treatment of temporary postoperative urinary retention after reconstructive pelvic surgery. PMID- 27714442 TI - Excess mortality following hip fracture: impact of self-perceived health, smoking, and body mass index. A NOREPOS study. AB - : Self-perceived health, smoking, and body mass index measured years before the hip fracture predicted excess post-hip fracture mortality, and even hip fracture patients with the most favorable levels of these risk factors had higher mortality than subjects who did not fracture. INTRODUCTION: This study aimed to investigate the impact of pre-fracture self-perceived health, smoking, and body mass index (BMI) on excess post-hip fracture mortality using matched peers without hip fracture as reference. METHODS: The study was based on the Cohort of Norway (CONOR) consisting of 10 regional health studies (1994-2003) and the NOREPOS hip fracture database (1994-2008). A matched cohort design was used to compare survival between hip fracture patients and subjects without fracture (matched on gender, age at participation in CONOR, and study site). Subjects aged >=60 years were included. Hazard ratios were estimated using stratified Cox regression. Age-standardized mortality was also calculated. RESULTS: Overall, hip fracture patients (N = 3177) had a 2.26-fold (95 % CI 2.13, 2.40) increased mortality compared to matched subjects (N = 20,282). The highest excess mortality was found in hip fracture patients reporting poor health (HR 4.08, 95 % CI 3.17, 5.26) and daily smoking (HR 3.25, 95 % CI 2.89, 3.66) and in patients with BMI <18.5 (HR 3.07, 95 % CI 2.11, 4.47) prior to the fracture. However, excess mortality was also observed in hip fracture patients in all other categories of BMI, self-perceived health, and smoking. CONCLUSIONS: Information on self perceived health, smoking, and BMI collected years before hip fracture predicted excess post-hip fracture mortality, and even hip fracture patients with the most favorable levels of these risk factors had higher mortality than the matched subjects who did not fracture. This suggests that both pre-fracture health status and factors related to the hip fracture itself might affect post-hip fracture mortality. PMID- 27714440 TI - Celiac disease is associated with reduced bone mineral density and increased FRAX scores in the US National Health and Nutrition Examination Survey. AB - : We investigated the association between celiac disease (CD) and bone mass density (BMD) and risk of osteoporotic fractures in the general US population. In children and men >=18 years, CD was associated with reduced BMD, and in men >=40 years, CD was associated with increased risk of osteoporotic fractures. INTRODUCTION: Celiac disease (CD) is an autoimmune condition, characterized by inflammation of the small intestine. CD has an increasing prevalence, and if unrecognized or untreated, CD can lead to complications from malabsorption and micronutrient deficiencies. We aimed to study whether CD is an independent predictor of reduced bone mineral density (BMD) and FRAX scores in the general US population. METHODS: We used data from the National Health and Nutrition Examination Survey, 2009-2010 and 2013-2014. CD was defined by positive tissue transglutaminase IgA antibody test. Multivariable models of BMD and FRAX scores were adjusted for BMI, serum 25-hydroxyvitamin D, vitamin D and calcium supplements, milk intake, serum calcium, and smoking status, when available. RESULTS: In children, aged 8-17 years, CD was associated with decreased Z-scores, by 0.85 for hip and 0.46 for spine (both P < 0.001). In men aged >= 18 years, CD was associated with 0.06 g/cm2 decrease in BMD in hip and with 0.11 g/cm2 decrease in BMD in spine (P = 0.08 and P < 0.001, respectively). In women, there were no statistically significant differences in the multiple-adjusted model. In men aged >= 40 years, CD predicted FRAX scores, resulting in increased scores by 2.25 % (P = 0.006) for hip fracture and by 2.43 % (P = 0.05) for major osteoporotic fracture. CD did not predict FRAX scores in women aged >=40 years. CONCLUSION: CD is independently associated with reduced BMD in children and adults aged >=18 years and is an independent risk factor of osteoporotic fractures in men aged >=40 years. PMID- 27714446 TI - Key elements of metabolomics in the study of biomarkers of diabetes. AB - Metabolomics is instrumental in the analysis of disease mechanisms and biomarkers of disease. The human metabolome is influenced by genetics and environmental interactions and reveals characteristic signatures of disease. Population studies with metabolomics require special study designs and care needs to be taken with pre-analytics. Gas chromatography coupled to mass spectrometry, liquid chromatography coupled to mass spectrometry or NMR are popular techniques used for metabolomic analyses in human cohorts. Metabolomics has been successfully used in the biomarker search for disease prediction and progression, for analyses of drug action and for the development of companion diagnostics. Several metabolites or metabolite classes identified by metabolomics have gained much attention in the field of diabetes research in the search for early disease detection, differentiation of progressor types and compliance with medication. This review summarises a presentation given at the 'New approaches beyond genetics' symposium at the 2015 annual meeting of the EASD. It is accompanied by another review from this symposium by Bernd Mayer (DOI: 10.1007/s00125-016-4032-2 ) and an overview by the Session Chair, Leif Groop (DOI: 10.1007/s00125-016-4014 4 ). PMID- 27714448 TI - Paul of Aegina (ca 625-690 AD), and his orthopaedic surgical reconstruction of the preternatural fingers. AB - Paul of Aegina lived in a era when the preservation of the ancient Greek tradition was for him almost a necessity. Eager to follow the dogma of "orhothetaopio(epsilon)deltaomega" (orthopodo: pace with no malformation), he introduced a series of surgical operations of reconstructive-cosmetic-plastic orthopaedic nature to confront any disfiguration of the human body. The aim of our study is to present the atmosphere of the era concerning the congenital malformations, describe briefly Paul's contribution on classic orthopaedics and present his views on the preternatural fingers. Our methodology mainly included the indexing of Paul's treatise, as published by the Sydenham Society during the nineteenth century, while references from the ancient Greek scholars were added to compose a better understanding of Paul's views. Inside his seven book treatise "Medical Compendium", he dedicated a separate chapter "On preternatural fingers, and on persons having six fingers", to introduce a detailed description of the extremities' additional digits and propose surgical treatment for their correction. He classified polydactylism according both to the presence of bones and to the anatomical origin of each additional finger. Paul marked the beginning of a new era for orthopaedics. PMID- 27714441 TI - Facilitators and barriers to exercise adherence in patients with osteopenia and osteoporosis: a systematic review. AB - : The aim of this study was to categorize the facilitators and barriers of exercise and identify methods to promote exercise adherence in the osteoporosis population. Despite the fair methodological quality of included randomized controlled trials (RCTs), less than 75 % identified facilitators and barriers to exercise. Methods to promote and measure exercise adherence were poorly reported. INTRODUCTION: Several studies have shown exercise to be successful in maintaining or increasing BMD in individuals with low bone mass. Yet, adherence to exercise is poor, with 50 % of those registered in an exercise program dropping out within the first 6 months, lack of time being the number one barrier in many populations. However, in the osteoporosis population, the main facilitator and barrier to exercise is still unclear. The aim of this study is to examine the extent to which RCTs reported the facilitators and the barriers to exercise and identified methods to promote adherence to an exercise program. METHODS: PubMed, CINHAL, EMBASE, and the Cochrane Review were queried using a predefined search criterion, and the resulting citations were imported into DistillerSR. Screening was carried out by two independent reviewers, and articles were included in the analysis by consensus. The methodological quality of included studies was assessed using the PEDro scale. RESULTS: Fifty-four RCTs examining exercise interventions in patients with osteopenia or osteoporosis were included. A spectrum of facilitators and barriers to exercise for osteoporotic patients were identified; however, no one facilitator was more frequently reported than the other. The most commonly reported barriers were lack of time and transportation. In most RCTs, methods to promote and measure exercise adherence were unsatisfactory. Of the 54 papers, 72 % reported an adherence rate to an exercise program; the lowest reported rate was 51.7 %, and the highest 100 %. CONCLUSIONS: Most RCTs found were of fair quality; however, less than three quarters identified facilitators and barriers to exercise. Reporting of methods to promote and measure exercise adherence were low. Future work should be directed toward identifying major facilitators and barriers to exercise adherence within RCTs. Only then can methods be identified to leverage facilitators and overcome barriers, thus strengthening the evidence for efficacy of optimal interventional exercise programs.

PMID- 27714447 TI - Alpha-defensin-novel synovial fluid biomarker for the diagnosis of periprosthetic joint infection. AB - PURPOSE: Periprosthetic joint infection (PJI) continues to be a significant complication after total joint arthroplasty. Diagnosis of PJI can be challenging and elusive in the absence of a gold standard. This purpose of this article is to review the current evidence on the utility of serum and synovial fluid biomarkers to help aid in the diagnosis of PJI with focusing on synovial fluid alpha defensin. METHODS: Articles and data for this review were identified by searches of PubMed and Ovid MEDLINE up to June 1, 2016. In addition, we manually reviewed the bibliographies of the retrieved articles for additional citations for references from relevant articles on the diagnosis of PJI. RESULTS: Serum biomarkers can be elevated in various inflammatory conditions. Synovial fluid biomarkers are more accurate for the diagnosis of PJI compared to serum biomarkers. Based on current available data, alpha-defensin is the most promising synovial fluid biomarker for the diagnosis of PJI and is commercially available. CONCLUSIONS: Synovial fluid alpha-defensin could enhance our ability to identify PJI and incorporate into the diagnostic algorithm in the future. Large-scale studies are needed to provide more data for its significance for the diagnosis of PJI. PMID- 27714451 TI - Kinematic femoral alignment with gap balancing and patient-specific instrumentation in total knee arthroplasty: a randomized clinical trial. AB - While patient-specific instrumentation (PSI) in total knee arthroplasty (TKA) allows for transfer of the preoperative plan onto bony landmarks, the soft tissue balancing is not affected. The goals of this randomized clinical trial were to compare PSI and the measured resection technique (conventional) with PSI and the gap balancing technique. Fifty patients were randomized to TKA with conventional PSI (PSI-S) (n = 25) or to PSI with additional gap balancing (PSI-GB) (n = 25). All patients were clinically examined at 3 and 12 months postoperatively. Data on the range of motion, the Knee Society Score, the Western Ontario and McMasters Universities Osteoarthritis Index, the High-Flexion Knee Score (HFKS), and the Forgotten Joint Score (FJS) were compiled at follow-up. Statistically significant improvements were found for all clinical parameters in the PSI-GB group compared to the PSI-S group at 3 months postoperatively and for FS, FJS, and HFKS at 12 months. However, the relevance of these differences, as well as their effect on long-term outcomes, needs to be evaluated further. In conclusion, patient specific instrumentation combined with gap balancing yielded good early clinical outcomes. PMID- 27714450 TI - Metabolic acidosis with hemodilution due to massive absorption of normal saline as bladder irrigation fluid following holmium laser enucleation of prostate. AB - Holmium laser enucleation of prostate (HoLEP) is being performed with increasing frequency as a minimally invasive alternative to transurethral resection of the prostate (TURP) for the surgical management of benign prostatic hyperplasia (BPH). HoLEP offers the advantage of use of normal saline for irrigation, instead of glycine which is utilized in TURP, decreasing the likelihood of fluid absorption and effects on serum electrolytes. We describe a patient who underwent HoLEP for BPH and subsequently developed non-ion gap metabolic acidosis and hemodilution associated with volume overload. PMID- 27714443 TI - Incident atrial fibrillation and the risk of fracture in the cardiovascular health study. AB - : In this prospective cohort of 4462 older adults, incident atrial fibrillation (AF) was not statistically significantly associated with subsequent risk of incident fracture. INTRODUCTION: AF is associated with stroke, heart failure, dementia, and death, but its association with fracture is unknown. Therefore, we examined the association of incident AF with the risk of subsequent fracture in the Cardiovascular Health Study (CHS) cohort. METHODS: Of the CHS participants aged >=65 years, 4462 were followed between 1991 and 2009, mean follow-up 8.8 years. Incident AF was identified by annual study electrocardiogram (ECG), hospital discharge diagnosis codes, or Medicare claims. Fractures of the hip, distal forearm, humerus, or pelvis were identified using hospital discharge diagnosis codes or Medicare claims. We used Cox proportional hazard models to estimate hazard ratios (HRs) and 95 % confidence intervals (CIs) for the association between incident AF (time-varying) and the risk of subsequent fracture. We also evaluated whether AF was associated with risk of sustaining a fall. RESULTS: Crude incident fracture rate was 22.9 per 1000 person-years in participants with AF and 17.7 per 1000 person-years in participants without AF. Individuals with incident AF were not at significantly higher risk of hip fracture (adjusted HR = 1.09, 95 % CI 0.83-1.42) or fracture at any selected site (adjusted HR = 0.97, 95 % CI 0.77-1.22) or risk of sustaining a fall (adjusted HR = 1.00, 95 % CI = 0.87-1.16) compared with those without AF. CONCLUSION: In this cohort of older, community-dwelling adults, incident AF was not shown to be associated with falls or hip or other fractures.

AB - Lignocellulosic biomass is the most abundant, low-cost, bio-renewable resource that holds enormous importance as alternative source for production of biofuels and other biochemicals that can be utilized as building blocks for production of new materials. Enzymatic hydrolysis is an essential step involved in the bioconversion of lignocellulose to produce fermentable monosaccharides. However, to allow the enzymatic hydrolysis, a pretreatment step is needed in order to remove the lignin barrier and break down the crystalline structure of cellulose. The present manuscript is dedicated to reviewing the most commonly applied "green" pretreatment processes used in bioconversion of lignocellulosic biomasses within the "biorefinery" concept. In this frame, the effects of different pretreatment methods on lignocellulosic biomass are described along with an in depth discussion on the benefits and drawbacks of each method, including generation of potentially inhibitory compounds for enzymatic hydrolysis, effect on cellulose digestibility, and generation of compounds toxic for the environment, and energy and economic demand. PMID- 27714452 TI - Malaria relapses were already known before 1900-a discussion. AB - For a long time, only two phases of the life cycle of the agents of malaria parasites were known: the cycle inside the mosquito body and the cycle in the red blood cells of humans as intermediate hosts. A possible tissue development cycle inside humans, however, had already been proposed before 1900. In general, Pieter Klaesz Pel is considered the first scientist who has described such a tissue cycle. However, a closer look at Pel's work shows that he still followed an old (conservative) way of thinking, since he still referred to "malaria poison and malaria miasma." Thus, the first idea of a possible tissue cycle must be searched in the work of earlier scientists. Referring to their observations on malaria, Vassilij Danilevsky, Arman Ruffer, Camillo Golgi and Battista Grassi suspected developing parasites in internal organs, before they can be found in the bloodstream. PMID- 27714453 TI - Life cycle and biology of Tristriata anatis (Digenea: Notocotylidae): morphological and molecular approaches. AB - Notocotylids are common digeneans parasitising birds and mammals. They have a two host life cycle with cercariae encysting in the open. Particular life cycles remain unknown for majority of notocotylid species, including a common parasite of sea ducks Tristriata anatis. Here we resolve the life cycle of T. anatis by means of D2 LSU, ITS1 and CO1 DNA sequence analysis, showing that the first intermediate hosts for this species are periwinkles Littorina spp. Morphological descriptions of rediae and cercariae are provided for the first time, and we also supplement the existing morphological data on adults. Apart from differential diagnosis, we discuss some features of cercariae and rediae biology, geographical distribution and host range. Our molecular data confirm that genus Tristriata is monotypic and that T. anatis has circumpolar distribution. CO1 sequence analysis has shown that isolation exists between the Atlantic and Pacific populations of T. anatis, suggesting that there are geographical races. We suppose that their formation may be linked to the Last Ice Age events, when trans-Arctic bird migrations ceased and periwinkle ranges shrunk. These made transfer of parasites across the Arctic impossible, and it still has not resumed. We discuss the possible influence of host vagility and adults' lifespan on digeneans' potential for geographical colonisation. PMID- 27714462 TI - Preoperative elevated platelet count and thrombocytosis in gynecologic malignancies. AB - PURPOSE: Platelets have multiple functions and they also play an important role in malignancies. Elevated platelet count and thrombocytosis at the time of diagnosis in patients with many solid tumors correlates with prognosis and is associated with poor survival. The aim of the following report is to review the literature concerning elevated platelet count and thrombocytosis in gynecologic malignancies. METHOD: A PubMed search of all English literature peer-reviewed publications was performed containing the terms elevated platelet count or thrombocytosis and vulvar cancer, cervical cancer, endometrial cancer, and ovarian cancer. All studies published until December 31, 2015, were included in the following review. RESULTS: A pretreatment elevated platelet count and thrombocytosis have been shown to be associated with a poor prognosis in many studies of gynecologic malignancies with the exception of vulvar carcinoma. CONCLUSION: Since elevated platelet count and thrombocytosis may be prevented by blocking thrombopoietic cytokines, their assessment may, in the future, be of therapeutic significance. PMID- 27714461 TI - Lithium chloride enhances bone regeneration and implant osseointegration in osteoporotic conditions. AB - Osteoporotic patients have a high risk of dental and orthopedic implant failure. Lithium chloride (LiCl) has been reported to enhance bone formation. However, the role of LiCl in the success rate of dental and orthopedic implants in osteoporotic conditions is still unknown. We investigated whether LiCl enhances implant osseointegration, implant fixation, and bone formation in osteoporotic conditions. Sprague-Dawley female rats (n = 18) were ovariectomized (OVX) to induce osteoporosis, and another nine rats underwent sham surgery. Three months after surgery, titanium implants were implanted in the tibia of the OVX and sham group rats. After implantation, the OVX rats were gavaged with 150 mg/kg/2 days of LiCl (OVX + LiCl group) or saline (OVX group), and sham group rats were gavaged with saline for 3 months. Implant osseointegration and bone formation were analyzed using histology, biomechanical testing, and micro computed tomography (micro-CT). More bone loss was observed in the OVX group compared to the control, and LiCl treatment enhanced bone formation and implant fixation in osteoporotic rats. In the OVX group, bone-implant contact (BIC) was decreased by 81.2 % compared to the sham group. Interestingly, the OVX + LiCl group showed 4.4 fold higher BIC compared to the OVX group. Micro-CT data of tibia from the OVX + LiCl group showed higher bone volume, trabecular thickness, trabecular number, and osseointegration compared to the OVX group. Maximum push-out force and implant-bone interface shear strength were 2.9-fold stronger in the OVX + LiCl group compared to the OVX group. In conclusion, LiCl enhanced implant osseointegration, implant fixation, and bone formation in osteoporotic conditions, suggesting LiCl as a promising therapeutic agent to prevent implant failure and bone loss in osteoporotic conditions. PMID- 27714454 TI - Plant-specific 4/1 polypeptide interacts with an endoplasmic reticulum protein related to human BAP31. AB - MAIN CONCLUSION: The plant-specific 4/1 protein interacts, both in yeast two hybrid system and in vitro, and co-localizes in plant cells with plant BAP-like protein, the orthologue of human protein BAP31. In yeast two-hybrid system, we identified a number of Nicotiana benthamiana protein interactors of Nt-4/1, the protein known to affect systemic transport of potato spindle tuber viroid. For one of these interactors, an orthologue of human B-cell receptor-associated protein 31 (BAP31) termed plant BAP-like protein (PBL), the ability to interact with Nt-4/1 was studied in greater detail. Analyses of purified proteins expressed in bacterial cells carried out in vitro with the surface plasmon resonance (SPR) spectroscopy revealed that the N. tabacum PBL (NtPBL) was able to interact with Nt-4/1 with high-affinity, and that their complex can form at physiologically relevant concentrations of both proteins. Subcellular localization studies of 4/1-GFP and NtPBL-mRFP transiently co-expressed in plant cells revealed the co-localization of the two fusion proteins in endoplasmic reticulum-associated bodies, suggesting their interaction in vivo. The N-terminal region of the Nt-4/1 protein was found to be required for the specific subcellular targeting of the protein, presumably due to a predicted amphipathic helix mediating association of the Nt-4/1 protein with cell membranes. Additionally, this region was found to contain a trans-activator domain responsible for the Nt-4/1 ability to activate transcription of a reporter gene in yeast. PMID- 27714459 TI - Sodium hyaluronate: an effective adjunct in temporomandibular joint arthrocentesis. AB - BACKGROUND: Internal derangement of the temporomandibular joint (TMJ) is one of the most common forms of temporomandibular disorders. The minimally invasive treatments such as arthrocentesis as well as arthroscopic lysis and lavage are often used as a first-line surgical treatment or in conjunction with nonsurgical modalities with low morbidity and high efficacy. Sodium hyaluronate (SH) has been proposed as an alternative therapeutic agent with similar therapeutic effects. OBJECTIVE: A prospective study was carried out for evaluation of efficacy of TMJ arthrocentesis with and without injection of SH in management of internal derangements. MATERIAL AND METHODS: A total of 30 patients suffering from internal derangement of TMJ were selected for this study. Patients were randomly divided into the following two groups: group 1-arthrocentesis-only group and group 2-arthrocentesis + SH group. Each group constituted 15 patients. RESULTS: Six-month postoperative mean mouth opening (MMO) increase was 13.61 +/- 1.64 and 15.53 +/- 3.01 mm in group 1 and group 2, respectively. At 6 months, there was marked improvement in masticatory efficiency with mean increase of 5.07 +/- 0.13 in group 1 and 6.40 +/- 0.04 in group 2. Mean pain reduction was 5.27 +/- 0.67 and 6.48 +/- 0.44 in group 1 and group 2, respectively. CONCLUSION: Although our series comprised a limited number of cases and a short follow-up period, initial results suggested that arthrocentesis with SH injection seemed to be superior to art.

AB - PURPOSE: This study aimed to evaluate the long-term efficacy of vagus nerve stimulation (VNS) in children and adolescents with intractable epilepsy and identify predictive factors for responsiveness to VNS. METHODS: Medical records of pediatric patients who underwent VNS implantation at two Korean tertiary centers were reviewed. At 0.5, 1, 3, and 5 years post-VNS implantation, the frequency of the most disabling seizures in each patient was assessed. Responders were defined as showing an overall 50 % reduction from baseline seizure frequency during follow-up. The clinical characteristics of responders and non-responders were compared. RESULTS: Among 58 patients, approximately half (29/58) were responders. The mean age at implantation was 10.9 years (range, 2.7-20.9) and the mean follow-up duration after VNS implantation was 8.4 years (range, 1-15.5). At 0.5, 1, 3, and 5 years after implantation, 43.1, 50.0, 56.9, and 58.1 % of patients exhibited >=50 % seizure frequency reduction disabling seizures. The patients with focal or multifocal epileptiform discharges were more likely to be responders than those with generalized epileptiform activities by video or conventional EEG at the time of VNS implantation (Pearson's and chi 2 test, p = 0.001). No other clinical variables were found to be associated with seizure outcomes. Wound infections caused VNS removal in two cases. All other adverse events, including cough and hoarseness, were tolerable. CONCLUSION: VNS is a well tolerated and effective adjuvant therapy in pediatric patients with intractable epilepsy. Notably, patients with focal epileptiform discharges alone rather than those with generalized epileptiform discharges maybe better candidates for VNS. PMID- 27714456 TI - Characterizing cerebral and locomotor muscle oxygenation to incremental ramp exercise in healthy children: relationship with pulmonary gas exchange. AB - AIMS: To characterize the oxygenation responses at cerebral and locomotor muscle level to incremental exercise in children and to assess the interrelationship with the pulmonary gas exchange responses. METHODS: Eighteen children (9 boys, 9 girls) (mean age 10.9 +/- 1.0 years) performed incremental cycle ramp exercise to exhaustion. The concentration of cerebral and muscle oxygenated (O2Hb) and deoxygenated (HHb) hemoglobin (by means of near-infrared spectroscopy) and pulmonary gas exchange was recorded. Cerebral and muscle O2Hb and HHb values were expressed as functions of oxygen uptake (VO2) and breakpoints were detected by means of double linear model analysis. The respiratory compensation point (RCP) was determined. The breakpoints in cerebral and muscle O2Hb and HHb were compared and correlated to RCP. RESULTS: The subjects reached peak power output of 105 +/- 18 W and VO2peak of 43.5 +/- 7.0 ml min-1 kg-1. Cerebral O2Hb increased to an intensity of 89.4 +/- 5.5 %VO2peak, where a breakpoint occurred at which cerebral O2Hb started to decrease. Cerebral HHb increased slightly to 88.1 +/- 4.8 %VO2peak, at which the increase was accelerated. Muscle HHb increased to 90.5 +/- 4.8 %VO2peak where a leveling-off occurred. RCP occurred at 89.3 +/- 4.3 %VO2peak. The breakpoints and RCP did not differ significantly (P = 0.13) and were strongly correlated (r > 0.70, P < 0.05). There were no differences between boys and girls (P = 0.43) and there was no significant correlation with VO2peak (P > 0.05). CONCLUSIONS: It was shown that cerebral and muscle oxygenation responses undergo significant changes as work rate increases and show breakpoints in the ongoing response at high intensity (85-95 %VO2peak). These breakpoints are strongly interrelated and associated with changes in pulmonary gas exchange. PMID- 27714445 TI - Human milk and mucosal lacto- and galacto-N-biose synthesis by transgalactosylation and their prebiotic potential in Lactobacillus species. AB - Lacto-N-biose (LNB) and galacto-N-biose (GNB) are major building blocks of free oligosaccharides and glycan moieties of glyco-complexes present in human milk and gastrointestinal mucosa. We have previously characterized the phospho-beta galactosidase GnbG from Lactobacillus casei BL23 that is involved in the metabolism of LNB and GNB. GnbG has been used here in transglycosylation reactions, and it showed the production of LNB and GNB with N-acetylglucosamine and N-acetylgalactosamine as acceptors, respectively. The reaction kinetics demonstrated that GnbG can convert 69 +/- 4 and 71 +/- 1 % of o-nitrophenyl-beta D-galactopyranoside into LNB and GNB, respectively. Those reactions were performed in a semi-preparative scale, and the synthesized disaccharides were purified. The maximum yield obtained for LNB was 10.7 +/- 0.2 g/l and for GNB was 10.8 +/- 0.3 g/l. NMR spectroscopy confirmed the molecular structures of both carbohydrates and the absence of reaction byproducts, which also supports that GnbG is specific for beta1,3-glycosidic linkages. The purified sugars were subsequently tested for their potential prebiotic properties using Lactobacillus species. The results showed that LNB and GNB were fermented by the tested strains of L. casei, Lactobacillus rhamnosus (except L. rhamnosus strain ATCC 53103), Lactobacillus zeae, Lactobacillus gasseri, and Lactobacillus johnsonii. DNA hybridization experiments suggested that the metabolism of those disaccharides in 9 out of 10 L. casei strains, all L. rhamnosus strains and all L. zeae strains tested relies upon a phospho-beta-galactosidase homologous to GnbG. The results presented here support the putative role of human milk oligosaccharides for selective enrichment of beneficial intestinal microbiota in breast-fed infants. PMID- 27714460 TI - Late onset postpartum psychoses. AB - It has been known since the eighteenth century that postpartum psychoses can begin several weeks after childbirth, not during the first fortnight. There are almost 400 non-organic episodes in the literature, starting more than 3 weeks after the birth; some of them are recurrent. The distinction of this disorder from early onset puerperal psychosis is supported by the distribution of onsets (which shows a steep fall after 14-15 days), survey data and the association with later pregnancies, not the first. Marce believed that these late onsets were related to the resumption of menstruation. This is a hypothesis worth investigating. PMID- 27714463 TI - Metacommunity ecology meets biogeography: effects of geographical region, spatial dynamics and environmental filtering on community structure in aquatic organisms. AB - Metacommunity patterns and underlying processes in aquatic organisms have typically been studied within a drainage basin. We examined variation in the composition of six freshwater organismal groups across various drainage basins in Finland. We first modelled spatial structures within each drainage basin using Moran eigenvector maps. Second, we partitioned variation in community structure among three groups of predictors using constrained ordination: (1) local environmental variables, (2) spatial variables, and (3) dummy variable drainage basin identity. Third, we examined turnover and nestedness components of multiple site beta diversity, and tested the best fit patterns of our datasets using the "elements of metacommunity structure" analysis. Our results showed that basin identity and local environmental variables were significant predictors of community structure, whereas within-basin spatial effects were typically negligible. In half of the organismal groups (diatoms, bryophytes, zooplankton), basin identity was a slightly better predictor of community structure than local environmental variables, whereas the opposite was true for the remaining three organismal groups (insects, macrophytes, fish). Both pure basin and local environmental fractions were, however, significant after accounting for the effects of the other predictor variable sets. All organismal groups exhibited high levels of beta diversity, which was mostly attributable to the turnover component. Our results showed consistent Clementsian-type metacommunity structures, suggesting that subgroups of species responded similarly to environmental factors or drainage basin limits. We conclude that aquatic communities across large scales are mostly determined by environmental and basin effects, which leads to high beta diversity and prevalence of Clementsian community types. PMID- 27714464 TI - Leaf anatomy of two reciprocally non-monophyletic mountain plants (Heliosperma spp.): does heritable adaptation to divergent growing sites accompany the onset of speciation? AB - Evolution is driven by natural selection, favouring individuals adapted in phenotypic traits to the environmental conditions at their growing site. To shed light on ecological and (epi-) genetically based differentiation between Heliosperma pusillum and Heliosperma veselskyi, two reciprocally non monophyletic, but morphologically and ecologically divergent species from the south-eastern Alps, we studied various leaf anatomical traits and investigated chloroplast ultrastructure in leaves of the two species grown either in their natural habitat or in a common garden. The alpine H. pusillum occurs in open, wet rock habitats, whereas its close relative H. veselskyi is restricted to dry, shady habitats below overhanging rocks in the montane belt. H. pusillum exhibited higher thickness of leaves and palisade layers as adjustments and/or adaptations to higher irradiance and a higher stomatal area index reflecting better water availability. Traits were adjusted plastically, but differed between species grown in a common garden, suggesting that the differentiation between the two species is not solely based on phenotypic plasticity but also has a genetic basis. Our study thus supports the hypothesis that differentiation between the highly interfertile species is likely driven by natural selection. PMID- 27714467 TI - Is the role of rhinoviruses as causative agents of pediatric community-acquired pneumonia over-estimated? AB - : The role that rhinoviruses, enteroviruses, parainfluenza viruses, coronaviruses and human bocavirus play in pediatric pneumonia is insufficiently studied. We used polymerase chain reaction (PCR) to study 9 virus groups, including 16 different viruses or viral strains, in 56 ambulatory children with radiologically confirmed community-acquired pneumonia (CAP). The same tests were carried out on 474 apparently healthy control children of the same age and sex. The mean age of children with CAP was 6.5 years (SD 4.2). Respiratory syncytial virus (RSV) was found in 19.6 % of 56 cases and in 2.1 % of 474 controls. Adenoviruses were present in 12.5 % of cases (0.2 % controls) and metapneumovirus and influenza A virus each in 10.7 % of cases (0.2 % controls). Interestingly, rhinoviruses were less common in cases (10.7 %) than in controls (22.4 %): odds ratio 0.36 (95%CI) 0.15-0.87) in conditional logistic regression including 56 cases and 280 controls matched for age, sex and sampling month. The prevalence of parainfluenza viruses, enteroviruses, coronaviruses and human bocavirus were similar in both groups. CONCLUSION: We conclude that the role of rhinoviruses as an etiology of pediatric CAP has been over-estimated, mainly due to the non-controlled designs of previous studies. What is Known: * In non-controlled studies, rhinovirus detection has been common, next to respiratory syncytial virus, in children with viral community-acquired pneumonia (CAP). * Enteroviruses, coronaviruses and the human bocavirus have been found less frequently. What is New: * In this controlled study, rhinoviruses were detected more often in healthy controls than in children with CAP, and enteroviruses, coronaviruses and human bocavirus were detected equally often in cases and controls. * We conclude that previous studies have over-estimated the role of rhinoviruses in the etiology of CAP in children. PMID- 27714466 TI - How I do it. The pedicled temporoparietal fascia flap for skull base reconstruction after endonasal endoscopic approaches. AB - BACKGROUND: Endoscopic endonasal approaches (EEA) are an alternative for removing challenging nasopharyngeal or skull base lesions. In some cases, a nasoseptal flap (NSF) is not always available and such complex procedures may lead to carotid arteries exposition and/or dura mater (DM) wide opening. Meticulous carotid coverage and DM reconstruction are crucial for preventing early and delayed complications. METHOD: We propose a step-by-step description of the pedicled temporoparietal fascia flap (TPFF) technique, with a focus on its pitfalls, advantages and limits. CONCLUSION: The TPFF is a reliable flap for skull base reconstruction when other pedicled flaps are not available. KEY POINTS: 1. Reliable flap even for irradiated patients 2. CT angiography with 3D reconstruction as pre-operative imaging 3. Doppler ultrasound probe to draw the artery's trajectory on skin 4. TPFF elevation concomitantly to the endoscopic procedure 5. Hemicoronal incision sufficient to harvest the TPFF 6. Superficial dissection in a plane just beneath the hair follicles 7. Dissection plane deep to the fad pad to preserve the frontal branch of the facial nerve 8. Surgical corridor wide enough to avoid any compression of the pedicle 9. Double visualization to avoid any twist and Doppler control of the STA patency 10. Close follow-up, toilet in clinics. PMID- 27714471 TI - Understanding toxicology: mechanisms and applications.

PMID- 27714474 TI - Predicting muscle fatigue: a response surface approximation based on proper generalized decomposition technique. AB - A novel technique is proposed to predict force reduction in skeletal muscle due to fatigue under the influence of electrical stimulus parameters and muscle physiological characteristics. Twelve New Zealand white rabbits were divided in four groups ([Formula: see text]) to obtain the active force evolution of in vitro Extensor Digitorum Longus muscles for an hour of repeated contractions under different electrical stimulation patterns. Left and right muscles were tested, and a total of 24 samples were used to construct a response surface based in the proper generalized decomposition. After the response surface development, one additional rabbit was used to check the predictive potential of the technique. This multidimensional surface takes into account not only the decay of the maximum repeated peak force, but also the shape evolution of each contraction, muscle weight, electrical input signal and stimulation protocol. This new approach of the fatigue simulation challenge allows to predict, inside the multispace surface generated, the muscle response considering other stimulation patterns, different tissue weight, etc. PMID- 27714457 TI - Identification and characterisation of Short Interspersed Nuclear Elements in the olive tree (Olea europaea L.) genome. AB - Short Interspersed Nuclear Elements (SINEs) are nonautonomous retrotransposons in the genome of most eukaryotic species. While SINEs have been intensively investigated in humans and other animal systems, SINE identification has been carried out only in a limited number of plant species. This lack of information is apparent especially in non-model plants whose genome has not been sequenced yet. The aim of this work was to produce a specific bioinformatics pipeline for analysing second generation sequence reads of a non-model species and identifying SINEs. We have identified, for the first time, 227 putative SINEs of the olive tree (Olea europaea), that constitute one of the few sets of such sequences in dicotyledonous species. The identified SINEs ranged from 140 to 362 bp in length and were characterised with regard to the occurrence of the tRNA domain in their sequence. The majority of identified elements resulted in single copy or very lowly repeated, often in association with genic sequences. Analysis of sequence similarity allowed us to identify two major groups of SINEs showing different abundances in the olive tree genome, the former with sequence similarity to SINEs of Scrophulariaceae and Solanaceae and the latter to SINEs of Salicaceae. A comparison of sequence conservation between olive SINEs and LTR retrotransposon families suggested that SINE expansion in the genome occurred especially in very ancient times, before LTR retrotransposon expansion, and presumably before the separation of the rosids (to which Oleaceae belong) from the Asterids. Besides providing data on olive SINEs, our results demonstrate the suitability of the pipeline employed for SINE identification. Applying this pipeline will favour further structural and functional analyses on these relatively unknown elements to be performed also in other plant species, even in the absence of a reference genome, and will allow establishing general evolutionary patterns for this kind of repeats in plants. PMID- 27714473 TI - Radiologists' Variation of Time to Read Across Different Procedure Types. AB - The workload of US radiologists has increased over the past two decades as measured through total annual relative value units (RVUs). This increase in RVUs generated suggests that radiologists' productivity has increased. However, true productivity (output unit per input unit; RVU per time) is at large unknown since actual time required to interpret and report a case is rarely recorded. In this study, we analyzed how the time to read a case varies between radiologists over a set of different procedure types by retrospectively extracting reading times from PACS usage logs. Specifically, we tested two hypotheses that; i) relative variation in time to read per procedure type increases as the median time to read a procedure type increases, and ii) relative rankings in terms of median reading speed for individual radiologists are consistent across different procedure types. The results that, i) a correlation of -0.25 between the coefficient of variation and median time to read and ii) that only 12 out of 46 radiologists had consistent rankings in terms of time to read across different procedure types, show both hypotheses to be without support. The results show that workload distribution will not follow any general rule for a radiologist across all procedures or a general rule for a specific procedure across many readers. Rather the findings suggest that improved overall practice efficiency can be achieved only by taking into account radiologists' individual productivity per procedure type when distributing unread cases. PMID- 27714478 TI - Clinically applied procedures for human ovarian tissue cryopreservation result in different levels of efficacy and efficiency. AB - PURPOSE: Different protocols are being used worldwide for the cryopreservation of human ovarian tissue for fertility preservation purposes. The efficiency and efficacy of the majority of these protocols has not been extensively evaluated, possibly resulting in sub-optimally cryopreserved ovarian tissue. To address the impact of this issue, we assessed the effects of two clinically successful human ovarian tissue slow-freezing cryopreservation procedures on the quality of the cryopreserved tissue. METHODS: To differentiate between cryopreservation (C) versus thawing (T) related effects, four combinations of these two (A and B) very different cryopreservation/thawing protocols (ACAT, ACBT, BCAT, BCBT) were studied. Before and after cryopreservation and thawing, the percentage of living and morphologically normal follicles, as well as the overall tissue viability, was assessed. RESULTS: Our experiments revealed that the choice of the cryopreservation protocol noticeably affected the overall tissue viability and percentage of living follicles, with a higher viability after protocol BC when compared to AC. No statistically significant differences in tissue viability were observed between the two thawing protocols, but thawing protocol BT required considerably more human effort and materials than thawing protocol AT. Tissue morphology was best retained using the BCAT combination. CONCLUSION: Our results indicate that extensive and systematical evaluation of clinically used protocols is warranted. PMID- 27714476 TI - Cardioprotection: Where to from here? AB - The size of the myocardial infarction remains an important therapeutic target, because heart attack size correlates with mortality and heart failure. In this era, myocardial infarct size is reduced primarily by timely reperfusion of the infarct related coronary artery. Whereas numerous pre-clinical studies have shown that certain pharmacologic agents and therapeutic maneuvers reduce myocardial infarction size greater than reperfusion alone, very few of these therapies have translated to successful clinical trials or standard clinical use. In this review we discuss both the recent successes as well as recent disappointments, and describe some of the newer potential therapies from the preclinical literature that have not yet been tested in clinical trials. PMID- 27714472 TI - Function-preserving gastrectomy based on the sentinel node concept in early gastric cancer. AB - Recent meta-analyses and a prospective multicenter trial of sentinel node (SN) mapping in early gastric cancer have demonstrated acceptable SN detection rates and accuracy of determination of lymph node status. SN mapping may play a key role in obtaining individual metastatic information. It also allows modification of surgical procedures, including function-preserving gastrectomy in patients with early gastric cancer. A dual-tracer method that uses radioactive colloids and blue dye is currently considered the most reliable method for the stable detection of SNs in patients with early gastric cancer. New technologies, such as indocyanine green infrared or fluorescence imaging, are also useful for accurate SN mapping in gastric cancer. Theoretically, laparoscopic function-preserving gastrectomy, including partial resection, proximal gastrectomy, segmental gastrectomy, and pylorus-preserving gastrectomy, is feasible in early gastric cancer when the SN(s) is/are nonmetastatic. Our study group conducted a multicenter prospective trial in Japan to evaluate function-preserving gastrectomy with SN mapping for long-term survival and patient quality of life. Non-exposed endoscopic wall-inversion surgery (NEWS) is a new technique for treating gastric cancer with partial resection involving full-thickness resection with endoscopy and laparoscopic surgery without transluminal access. The combination of NEWS and SN biopsy is expected to be a promising, minimally invasive, function-preserving surgery that is ideal for cases of cN0 early gastric cancer. PMID- 27714465 TI - IgA nephropathy with presentation of nephrotic syndrome at onset in children. AB - BACKGROUND: Despite a low incidence, nephrotic syndrome (NS) can present with IgA nephropathy (IgAN). The clinical characteristics and long-term outcomes of pediatric patients with IgAN presenting with NS (NS-IgAN) at onset have not been fully elucidated. METHODS: We retrospectively analyzed 426 patients, and compared clinical and pathological (Oxford) findings between those with NS-IgAN and those with non-NS-IgAN. RESULTS: Among 426 patients, 30 (7.0 %) had NS-IgAN. Logistic analyses showed that male sex (OR: 7.6, p = 0.0002), M1 (OR: 10.3, p = 0.002), and E1 (OR: 15.2, p = 0.0001) were significantly related to NS. The mean observation period was 6.2 +/- 3.2 years. Although NS-IgAN was associated with significantly lower renal survival than non-NS-IgAN according to Kaplan-Meier analysis (p = 0.02), renal survival of NS-IgAN was good (92.4 % at 10 years). The most significant prognostic factor for renal survival was remission of proteinuria after treatment, and NS at onset is also a significant prognostic factor for renal survival after adjusting for remission of proteinuria. Twenty children with NS-IgAN were treated with prednisolone alone, or prednisolone and immunosuppressant. Remission of proteinuria occurred in 21 patients. Three cases of NS-IgAN progressed to stage III-V chronic kidney disease at the most recent observation. They all demonstrated heavy proteinuria after the 2-year initial treatment. The significant factor for persistent proteinuria at 5 years was S1 in NS-IgAN. CONCLUSIONS: The most significant factor for renal survival was responsiveness to treatment, not NS itself. As modifiable acute lesions are the dominant pathological findings in NS-IgAN, histological improvements achieved by appropriate treatments can result in a favorable prognosis. PMID- 27714481 TI - TP53 and CDKN1A mutation analysis in families with Li-Fraumeni and Li-Fraumeni like syndromes. AB - Li-Fraumeni and Li-Fraumeni like syndromes (LFS/LFL) represent rare cancer-prone conditions associated mostly with sarcomas, breast cancer, brain tumors, and adrenocortical carcinomas. TP53 germline mutations are present in up to 80 % of families with classic Li-Fraumeni syndrome, and in 20-60 % of families with Li Fraumeni like phenotypes. The frequency of LFS/LFL families with no TP53 mutations detected suggests the involvement of other genes in the syndrome. In this study, we searched for mutations in TP53 in 39 probands from families with criteria for LFS/LFL. We also searched for mutations in the gene encoding the main mediator of p53 in cell cycle arrest, CDKN1A/p21, in all patients with no mutations in TP53. Eight probands carried germline disease-causing mutations in TP53: six missense mutations and two partial gene deletions. No mutations in CDKN1A coding region were detected. TP53 partial deletions in our cohort represented 25 % (2/8) of the mutations found, a much higher frequency than usually reported, emphasizing the need to search for TP53 rearrangements in patients with LFS/LFL phenotypes. Two benign tumors were detected in two TP53 mutation carriers: an adrenocortical adenoma and a neurofibroma, which raises a question about the possible implication of TP53 mutations on the development of such lesions. PMID- 27714469 TI - Ambulatory 24-h ECG monitoring and cardiovascular autonomic assessment for the screening of silent myocardial ischemia in elderly type 2 diabetic hypertensive patients. AB - The aim of the study was to evaluate the usefulness of Holter monitoring for the detection of silent myocardial ischemia (SMI) in elderly type 2 diabetic patients with hypertension and the possible relationship between SMI and cardiovascular autonomic neuropathy (CAN). Two hundred and forty-three asymptomatic outpatients, aged 65-75 years, with type 2 diabetes and essential hypertension underwent 24-h ECG monitoring and 5 tests for the evaluation of both parasympathetic (heart rate variability, response to breath deeping, and Valsalva manoeuvre) and sympathetic (cold pressor test and orthostatic hypotension test) autonomic function. A total of 518 asymptomatic episodes of ST depression during Holter monitoring indicative of SMI were detected in 51 of the 243 studied patients (20.9 %). None of the patients with ST depression episodes exhibited a normal response to at least one of the evaluated autonomic function tests, whereas 22 of the 192 patients without ST changes (11.4 %) exhibited a normal response to all tests. Abnormality in both parasympathetic and sympathetic function test responses was found in 94.1 % of patients with ST depression episodes vs 26.1 % of those without ST changes (P < 0.001). Statistical evaluation of the relationship between the abnormal response to single autonomic function test and episodes of ST depression was highly significant for all the 5 tests (P < 0.001). These results indicate that: (a) Holter monitoring enables to detect ST segment changes indicative of SMI in 20.9 % of elderly diabetic patients with hypertension; (b) the presence of autonomic cardiac dysfunction in these patients suggests a role of diabetic neuropathy in the pathogenesis of SMI; and PMID- 27714479 TI - Clinical pregnancy rate following frozen embryo transfer is higher with blastocysts vitrified on day 5 than on day 6. AB - PURPOSE: The aim of this study was to compare the pregnancy rates between good quality blastocysts vitrified on day 6 versus blastocysts vitrified on day 5 after fertilization. METHODS: This is a retrospective cohort study of 791 freeze thaw cycles of blastocysts vitrified either on day 5 or on day 6 and transferred between January 2012 and October 2015. Five hundred and thirty-seven cycles included blastocysts vitrified on day 5, and 254 cycles included blastocysts vitrified on day 6. RESULTS: The age of the patients and the proportion of embryos that survived the thawing process were comparable between the two groups. More good quality embryos were transferred in the group in which blastocysts were vitrified on day 6 (1.2 vs. 1.3, p = 0.005), but the clinical pregnancy rate (44 vs. 33 %, p = 0.002) and the ongoing pregnancy rate (41 vs. 28 %, p < 0.001) were higher in the group in which blastocysts were vitrified on day 5. Multivariate regression analysis adjusting for patient's age, number of good quality embryos transferred (>=3BB), and treatment protocol demonstrated that the day 6 vitrified group had a significantly lower clinical pregnancy rate compared to the day 5 vitrified group (OR 0.54, 95 % CI 0.38-0.76). CONCLUSIONS: The clinical pregnancy rate following frozen embryo transfer is significantly lower with blastocysts vitrified on day 6 compared to blastocysts vitrified on day 5. PMID- 27714477 TI - Targeted, Site-specific quantitation of N- and O-glycopeptides using 18O-labeling and product ion based mass spectrometry. AB - The site-specific quantitation of N- and O-glycosylation is vital to understanding the function(s) of different glycans expressed at a given site of a protein under physiological and disease conditions. Most commonly used precursor ion intensity based quantification method is less accurate and other labeled methods are expensive and require enrichment of glycopeptides. Here, we used glycopeptide product (y and Y0) ions and 18O-labeling of C-terminal carboxyl group as a strategy to obtain quantitative information about fold-change and relative abundance of most of the glycoforms attached to the glycopeptides. As a proof of concept, the accuracy and robustness of this targeted, relative quantification LC-MS method was demonstrated using Rituximab. Furthermore, the N glycopeptide quantification results were compared with a biosimilar of Rituximab and validated with quantitative data obtained from 2-AB-UHPLC-FL method. We further demonstrated the intensity fold-change and relative abundance of 46 unique N- and O-glycopeptides and aglycopeptides from innovator and biosimilar samples of Etanercept using both the normal-MS and product ion based quantitation. The results showed a very similar site-specific expression of N- and O-glycopeptides between the samples but with subtle differences. Interestingly, we have also been able to quantify macro-heterogeneity of all N- and O-glycopetides of Etanercept. In addition to applications in biotherapeutics, the developed method can also be used for site-specific quantitation of N- and O glycopeptides and aglycopeptides of glycoproteins with known glycosylation pattern. PMID- 27714484 TI - Reliability and Validity of a Newly Developed Measure of Citizenship Among Persons with Mental Illnesses. AB - Following development of a 46-item of measure citizenship, a framework for supporting the full membership in society of persons with mental illness, this study tested the measure's reliability and validity. 110 persons from a mental health center completed a questionnaire packet containing the citizenship measure and other measures to assess internal consistency and validity of the citizenship instrument. Correlation matrices were examined for associations between the citizenship instrument and other measures. Stepwise regression examines demographic factors, sense of community, and social capital as predictors of citizenship, recovery, and well-being. Analyses revealed that the measure is psychometrically sound. The measure captures subjective information about the degree to which individuals experience rights, sense of belonging, and other factors associated with community membership that have been previously difficult to assess. The measure establishes a platform for interventions to support the full participation in society of persons with mental illnesses. PMID- 27714483 TI - Developmental Trajectories of Youth Conduct Problems: Testing Later Development and Related Outcomes in a 12-Year Period. AB - Developmental heterogeneity of youth conduct problems has been widely assumed, leading to the identification of distinctive groups at particular risk of more serious problems later in development. The present study intends to expand the main results of a prior study focused on identifying developmental trajectories of conduct problems (Stable-low, Stable-high, and Decreasing), by analyzing their developmental course and related outcomes during middle/late adolescence and early adulthood. Two follow-up studies were conducted 10 and 12 years after the initial study with 115 and 122 youths respectively (mean = 17.29 and 19.18). Overall results underline that the Early-onset persistent group showed the highest risk-profile; the Childhood-limited group revealed a moderate level of later maladjustment; and the Adolescence-onset group, currently identified, showed a significant peak of risk particularly in middle/late adolescence. These findings provide a more comprehensive representation of youth conduct problems, and open new means of discussion in terms of preventive intervention. PMID- 27714470 TI - Oak protein profile alterations upon root colonization by an ectomycorrhizal fungus. AB - An increased knowledge on the real impacts of ectomycorrhizal symbiosis in forest species is needed to optimize forest sustainable productivity and thus to improve forest services and their capacity to act as carbon sinks. In this study, we investigated the response of an oak species to ectomycorrhizae formation using a proteomics approach complemented by biochemical analysis of carbohydrate levels. Comparative proteome analysis between mycorrhizal and nonmycorrhizal cork oak plants revealed no differences at the foliar level. However, the protein profile of 34 unique oak proteins was altered in the roots. Consistent with the results of the biochemical analysis, the proteome analysis of the mycorrhizal roots suggests a decreasing utilization of sucrose for the metabolic activity of mycorrhizal roots which is consistent with an increased allocation of carbohydrates from the plant to the fungus in order to sustain the symbiosis. In addition, a promotion of protein unfolding mechanisms, attenuation of defense reactions, increased nutrient mobilization from the plant-fungus interface (N and P), as well as cytoskeleton rearrangements and induction of plant cell wall loosening for fungal root accommodation in colonized roots are also suggested by the results. The suggested improvement in root capacity to take up nutrients accompanied by an increase of root biomass without apparent changes in aboveground biomass strongly re-enforces the potential of mycorrhizal inoculation to improve cork oak forest resistance capacity to cope with coming climate change. PMID- 27714480 TI - Impact of spinal cord compression from intradural and epidural spinal tumors on perioperative symptoms-implications for surgical decision making. AB - Spinal cord or cauda equina compression (SCC) is an increasing challenge in clinical oncology due to a higher prevalence of long-term cancer survivors. Our aim was to determine the clinical relevance of SCC regarding patient outcome depending on different tumor entities and their anatomical localization (extradural/intradural/intramedullary). We retrospectively analyzed 230 patients surgically treated for SCC. Preoperative status for pain and neurological impairment were correlated to the degree of compression, tumor location, and early as well as short-term follow-up outcome parameters. Interestingly, we did not observe any differences between intradural-extramedullary compared to extradural tumors. Unilaterally localized tumors were likely to present with pain (72.9 %, p < 0.01), whereas concentric growth was associated with motor deficits (41.0 %, p < 0.01, as primary symptom, 49.3 % on admission, p < 0.05). In concentric tumors, the pain pattern was diffuse (40.5 % vs. 17.5 in unilateral disease, p < 0.01), whereas unilateral tumors resulted in localized pain (61.4 % local axial or radicular, p < 0.01). Diffuse pain, patients without a sensory or motor deficit, progressive disease, cervical localization, and a higher degree of stenosis were identified as beneficial for an early improvement in pain (p < 0.05). Notably, 29 % of patients with unchanged pain and 30.8 % with unchanged neurologic function at day 7 postoperative improved during follow-up (p < 0.001). Our data demonstrate that the preoperative tumor anatomy in patients with SCC was closely related to their presenting symptoms and early clinical outcome. The detailed analysis elucidates the biology of SCC and might thereby aid in determining which patients will benefit from surgery. PMID- 27714482 TI - Biosimilars in rheumatic diseases: structural and functional variability that may impact clinical and regulatory decisions. AB - Biologics as therapeutic interventions for human disease represent both a distinctly modern novelty and an echo of ancient, or at least old, medical practice. The similarity lies in the sense that in both the synthetic effort occurs in living organisms (an extract of a plant, animal tissue, or a cell culture) while the difference is apparent in the bioengineering required in modern methods and the corresponding flexibility to customize the therapeutic product. Although the concept of looking to living systems as a source of medically useful compounds either for research or for actual patient care has never vanished, the development of biochemistry and advances in medicinal chemistry made production by total synthesis the standard for a safe, reliable, and commercial drug production at sufficient scale. In this interval was where much of the modern apparatus for approving medical therapies came to be developed, and as such, the most proper extension of the regulatory regime to modern biologics is not entirely obvious. In particular, the notion of generics for off-patent conventional pharmaceuticals and their role in the marketplace with respect to increasing the accessibility of treatment is not congruent with the relationship between what are known as biosimilars and off-patent originating biologics. In this article, we review elements of the scientific basis for challenges in the production, use, and regulation of biosimilars. In light of these advances, we propose suggestions to modify constraints on biosimilar regulations in the interest of patient care and access to therapies. PMID- 27714468 TI - Disc associating axial pain were indicated by PLL resection in ACDF surgery. AB - PURPOSE: The generation and tissue origination of disc-associated axial pain is still under exploration. This study was performed to evaluate disc-associated axial pain and to explore whether it originates in the disc or its surrounding components. METHODS: A 6-year series of 88 single-level Smith-Robinson disc and posterior longitudinal ligament (PLL) resections performed to treat single-level cervical spondylotic myelopathy was retrospectively examined. All single-level anterior disc decompressions were performed under local infiltration anesthesia; the PLL was not anesthetized to avoid cervical cord block. The patients were grouped by disc level. The centered foci of the pain localization were subjectively recorded before, during, and after the operation. Radiological examinations (plain X-ray, computed tomography, and magnetic resonance imaging) were performed before and after the operation to diagnose the compression and evaluate the decompression. RESULTS: All 88 patients who underwent single-level PLL resection had no intraoperative pain responses except during resection of the PLL. Their provoked pain responses were similar to their familiar pain responses. The axial pain disappeared postoperatively. Complications developed in six patients (6.8 %). All patients recovered well, and the absence of the axial pain was maintained at the 12-month follow-up. CONCLUSIONS: Preoperative axial pain due to single-level disc protrusion was triggered and aggravated only during PLL resection and disappeared postoperatively. This implies that the intervertebral PLL could be the site of origination of axial pain. Axial pain from the PLL at different disc levels had different distributions.

AB - Hepatitis virus infection is a leading cause of chronic liver disease, including cirrhosis and hepatocellular carcinoma (HCC). Although anti-viral therapies against hepatitis B virus (HBV) and hepatitis C virus (HCV) have dramatically progressed during the past decade, the estimated number of people chronically infected with HBV and/or HCV is ~370 million, and hepatitis virus-associated hepatocarcinogenesis is a serious health concern worldwide. Understanding the mechanism of virus-associated carcinogenesis is crucial toward both treatment and prevention, and the recently developed whole genome/exome sequencing analysis using next-generation sequencing technologies has contributed to unveiling the landscape of genetic and epigenetic aberrations in not only tumor tissues but also the background liver tissues underlying chronic liver damage caused by hepatitis virus infection. Several major mechanisms underlie the genetic and epigenetic aberrations in the hepatitis virus-infected liver, such as the generation of reactive oxidative stress, ectopic expression of DNA mutator enzymes, and dysfunction of the DNA repair system. In addition, direct oncogenic effects of hepatitis virus, represented by the integration of HBV-DNA, are observed in infected hepatocytes. Elucidating the whole picture of genetic and epigenetic alterations, as well as the mechanisms of tumorigenesis, will facilitate the development of efficient treatment and prevention strategies for hepatitis virus-associated HCC. PMID- 27714486 TI - Optimized workflow and imaging protocols for whole-body oncologic PET/MRI. AB - Although PET/MRI has the advantages of a simultaneous acquisition of PET and MRI, high soft-tissue contrast of the MRI images, and reduction of radiation exposure, its low profitability and long acquisition time are significant problems in clinical settings. Thus, MRI protocols that meet oncological purposes need to be used in order to reduce examination time while securing detectability. Currently, half-Fourier acquisition single-shot turbo spin echo and 3D-T1 volumetric interpolated breath-hold examination may be the most commonly used sequences for whole-body imaging due to their shorter acquisition time and higher diagnostic accuracy. Although there have been several reports that adding diffusion weighted image (DWI) to PET/MRI protocol has had no effect on tumor detection to date, in cases of liver, kidney, bladder, and prostate cancer, the use of DWI may be beneficial in detecting lesions. Another possible option is to scan each region with different MRI sequences instead of scanning the whole body using one sequence continuously. We herein report a workflow and imaging protocols for whole-body oncologic PET/MRI using an integrated system in the clinical routine, designed for the detection, for example by cancer screening, of metastatic lesions, in order to help future users optimize their workflow and imaging protocols. PMID- 27714487 TI - Neuroimaging findings of Zika virus infection: a review article. AB - Zika virus (ZIKV) is an arbovirus from the Flaviviridae family. It is usually transmitted by mosquito bite. There have been no reports of severe symptoms caused by ZIKV infection up until the last few years. In October 2013 an outbreak was reported in French Polynesia with severe neurological complications in some affected cases. In November 2015, the Ministry of Health of Brazil attributed the increased number of neonatal microcephaly cases in northeastern Brazil to congenital ZIKV infection. The rapid spread of the virus convinced the World Health Organization to announce ZIKV infection as a "Public Health Emergency of International Concern" in February 2016. The main neuroimaging findings in congenital ZIKV infection include microcephaly which is the hallmark of the disease, other malformations of cortical development (e.g., lissencephaly, heterotopia, etc.), parenchymal calcifications, unilateral or bilateral ventriculomegaly, enlarged extra-axial CSF spaces, dysgenesis of the corpus callosum, agenesis of the cavum septum pellucidum, cerebellar and brainstem hypoplasia, and ocular abnormalities. ZIKV infection may also cause Guillain Barre syndrome and acute disseminated encephalomyelitis in adults. Familiarity with neuroimaging findings of congenital and acquired ZIKV infection is crucial to suspect this disease in residents of endemic regions and travelers to these areas. PMID- 27714489 TI - Novel interaction between CCR4 and CAF1 in rice CCR4-NOT deadenylase complex. AB - KEY MESSAGE: Rice is an important crop in the world. However, little is known about rice mRNA deadenylation, which is an important regulation step of gene expression at the post-transcriptional level. The CCR4-NOT1 complex contains two key components, CCR4 and CAF1, which are the main cytoplasmic deadenylases in eukaryotic cells. In yeast and humans, CCR4 can interact with CAF1 via its N terminal LRR domain. However, no CCR4 protein containing N-terminal LRR motifs have been found in plants. In this manuscript, we demonstrate a novel pattern of interaction between OsCCR4 and OsCAF1 in the rice CCR4-NOT complex, and that OsCAF1 acts as a bridge between OsCCR4 and OsNOT1 in this complex. Our results revealed that the Mynd-like domain at the N-terminus of rice CCR4 proteins and the PXLXP motif at the rice CAF1 N-terminus play critical roles in OsCCR4-OsCAF1 interaction. Deadenylation, also called poly(A) tail shortening, is the first rate-limiting step in general cytoplasmic mRNA degradation in eukaryotic cells. Carbon catabolite repressor (CCR)4 and CCR4-associated factor (CAF)1 in the CCR4 NOT complex function in mRNA poly(A) tail shortening. CCR4s contain N-terminal leucine-rich repeat (LRR) motifs that interact with CAF1s in yeast, fruit fly and mammals. In silico analysis has not identified any plant CCR4 proteins that contain LRR motifs. Here, two rice CCR4 homologous genes, OsCCR4a and OsCCR4b, were identified. The isolated recombinant exonuclease-endonuclease-phosphatase domain of OsCCR4a and OsCCR4b exhibited 3'-5' exonuclease activity in vitro, and point mutation of a catalytic residue in this domain disrupted the deadenylase activity. Both OsCCR4a and OsCCR4b fluorescent fusion proteins were localized in the rice cytoplasm and nucleus, and both associated with processing bodies via their N-terminus. Binding analyses showed that OsCCR4a and OsCCR4b directly interacted with three rice CAF1 family members: OsCAF1A, OsCAF1G and OsCAF1H. The zf-MYND-like domain at the N terminus of rice CCR4 and the PXLXP motif of rice CAF1 play critical roles in OsCCR4-OsCAF1 interaction. OsCAF1 proteins, but not OsCCR4 proteins, can interact with the MIG4G domain of rice OsNOT1. Our studies thus reveal a hitherto undiscovered novel interaction pattern that connects OsCCR4 and OsCAF1 in the rice CCR4-NOT complex. PMID- 27714485 TI - A Pilot Study of Fragile X Syndrome Screening in Pregnant Women and Women Planning Pregnancy: Implementation, Acceptance, Awareness, and Geographic Factors. AB - We report herein results of a study performed in the Balearic Islands which had the following goals: 1) Determine the proportion of pregnant or non-pregnant women planning pregnancy, who would choose to undergo a screening test for Fragile X Syndrome (FXS), if it is accompanied by the appropriate information; 2) Assess satisfaction and any increase in stress among women who participate in screening; 3) Collect epidemiological information about the incidence of the disease in our population; and 4) Collect demographic and health history data and assess participants' awareness of the disease. Screening was performed on 3,731 pregnant and non-pregnant women of childbearing age and the results indicate: a very high voluntary rate of participation; a high level of self-reported satisfaction and low levels of stress because of the test; a very high incidence of premutation (1/106) in our population; and a low level of awareness about the existence of FXS (25 %). Additional findings indicate no significant correlation between self-reported health history and premutation detection, and the high premutation incidence does not seem to be specific to the indigenous Balearic population. Based on these results, we discuss the pros and cons of an implementation of preconception and pregnant women screening for FXS within a public health screening program. PMID- 27714491 TI - Early Sex Work Initiation and Violence against Female Sex Workers in Mombasa, Kenya. AB - Between 20 and 40 % of female sex workers (FSWs) began sex work before age 18. Little is known concerning whether early initiation of sex work impacts later experiences in adulthood, including violence victimization. This paper examines the relationship between early initiation of sex work and violence victimization during adulthood. The sample included 816 FSWs in Mombasa, Kenya, recruited from HIV prevention drop-in centers who were 18 years or older and moderate-risk drinkers. Early initiation was defined as beginning sex work at 17 or younger. Logistic regression modeled recent violence as a function of early initiation, adjusting for drop-in center, age, education, HIV status, supporting others, and childhood abuse. Twenty percent of the sample reported early initiation of sex work. Although both early initiators and other FSWs reported commonly experiencing recent violence, early initiators were significantly more likely to experience recent physical and sexual violence and verbal abuse from paying partners. Early initiation was not associated with physical or sexual violence from non-paying partners. Many FSWs begin sex work before age 18. Effective interventions focused on preventing this are needed. In addition, interventions are needed to prevent violence against all FSWs, in particular, those who initiated sex work during childhood or adolescence. PMID- 27714492 TI - Carcass characteristics and meat quality of lambs fed babassu cake (Orbignya speciosa) as a replacement for elephant grass silage. AB - The study aimed to evaluate the effect of the partial replacement of elephant grass silage with babassu cake (Orbignya speciosa) on the carcass characteristics and meat quality of feedlot lambs. Forty-five castrated male Santa Ines sheep (19.08 +/- 0.41 kg) approximately 4 months old were distributed in a completely randomized design, with five treatments 0.0, 12.5, 25.0, 37.5 and 50 % (%DM) replacement of babassu cake with silage forming isoproteic diets formulated at a ratio of 40 % roughage to 60 % concentrate. All of the studied animals were slaughtered at the end of the experiment. The liver weights and yields increased with the inclusion of babassu cake. The weight of the shoulder increased from 2.31 to 2.61 kg, while the loin yield decreased from 7.38 to 6.64 % with the inclusion of babassu cake, both linearly. The body length, thoracic perimeter, rump perimeter and carcass compactness index showed high and positive correlations with the hot and cold carcass weights. The myofibrillar fragmentation index decreased linearly as a function of the inclusion level of babassu cake, but other quality variables were not affected. The replacement of up to 50 % of the elephant grass silage with babassu cake in the diet of lambs does not cause negative effects on carcass characteristics or meat quality. PMID- 27714493 TI - Improved pose and affinity predictions using different protocols tailored on the basis of data availability. AB - The D3R 2015 grand drug design challenge provided a set of blinded challenges for evaluating the applicability of our protocols for pose and affinity prediction. In the present study, we report the application of two different strategies for the two D3R protein targets HSP90 and MAP4K4. HSP90 is a well-studied target system with numerous co-crystal structures and SAR data. Furthermore the D3R HSP90 test compounds showed high structural similarity to existing HSP90 inhibitors in BindingDB. Thus, we adopted an integrated docking and scoring approach involving a combination of both pharmacophoric and heavy atom similarity alignments, local minimization and quantitative structure activity relationships modeling, resulting in the reasonable prediction of pose [with the root mean square deviation (RMSD) values of 1.75 A for mean pose 1, 1.417 A for the mean best pose and 1.85 A for the mean all poses] and affinity (ROC AUC = 0.702 at 7.5 pIC50 cut-off and R = 0.45 for 180 compounds). The second protein, MAP4K4, represents a novel system with limited SAR and co-crystal structure data and little structural similarity of the D3R MAP4K4 test compounds to known MAP4K4 ligands. For this system, we implemented an exhaustive pose and affinity prediction protocol involving docking and scoring using the PLANTS software which considers side chain flexibility together with protein-ligand fingerprints analysis assisting in pose prioritization. This protocol through fares poorly in pose prediction (with the RMSD values of 4.346 A for mean pose 1, 4.69 A for mean best pose and 4.75 A for mean all poses) and produced reasonable affinity prediction (AUC = 0.728 at 7.5 pIC50 cut-off and R = 0.67 for 18 compounds, ranked 1st among 80 submissions). PMID- 27714490 TI - A genetic genomics-expression approach reveals components of the molecular mechanisms beyond the cell wall that underlie peach fruit woolliness due to cold storage. AB - Peach fruits subjected to prolonged cold storage (CS) to delay decay and over ripening often develop a form of chilling injury (CI) called mealiness/woolliness (WLT), a flesh textural disorder characterized by lack of juiciness. Transcript profiles were analyzed after different lengths of CS and subsequent shelf life ripening (SLR) in pools of fruits from siblings of the Pop-DG population with contrasting sensitivity to develop WLT. This was followed by quantitative PCR on pools and individual lines of the Pop-DG population to validate and extend the microarray results. Relative tolerance to WLT development during SLR was related to the fruit's ability to recover from cold and the reactivation of normal ripening, processes that are probably regulated by transcription factors involved in stress protection, stress recovery and induction of ripening. Furthermore, our results showed that altered ripening in WLT fruits during shelf life is probably due, in part, to cold-induced desynchronization of the ripening program involving ethylene and auxin hormonal regulation of metabolism and cell wall. In addition, we found strong correlation between expression of RNA translation and protein assembly genes and the visual injury symptoms. PMID- 27714495 TI - Molecular and biological properties of an endornavirus infecting winged bean (Psophocarpus tetragonolobus). AB - A double-stranded RNA (dsRNA) of approximately 15 kbp was isolated from asymptomatic winged bean (Psophocarpus tetragonolobus) plants. The size of the dsRNA, together with results of RT-PCR testing, suggested that it was the replicative form of a plant endornavirus. Cloning, sequencing, and sequence analyses confirmed the endornavirus nature of the dsRNA. Conserved motifs typical for endornaviruses were identified and their amino acid sequences compared with those of selected endornaviruses. Phylogenetic analyses revealed a close relationship with Bell pepper endornavirus, Phaseolus vulgaris endornavirus 2, and Hot pepper endornavirus. The dsRNA was present in most P. tetragonolobus genotypes tested. The virus was provisionally named Winged bean endornavirus 1 (WBEV-1). PMID- 27714494 TI - Role of R292K mutation in influenza H7N9 neuraminidase toward oseltamivir susceptibility: MD and MM/PB(GB)SA study. AB - The H7N9 avian influenza virus is a novel re-assortment from at least four different strains of virus. Neuraminidase, which is a glycoprotein on the surface membrane, has been the target for drug treatment. However, some H7N9 strains that have been isolated from patient after drug treatment have a R292K mutation in neuraminidase. This substitution was found to facilitate drug resistance using protein- and virus- assays, in particular it gave a high resistance to the most commonly used drug, oseltamivir. The aim of this research is to understand the source of oseltamivir resistance using MD simulations and the MM/PB(GB)SA binding free energy approaches. Both methods can predict the reduced susceptibility of oseltamivir in good agreement to the IC 50 binding energy, although MM/GBSA underestimates this prediction compared to the MM/PBSA calculation. Electrostatic interaction is the main contribution for oseltamivir binding in terms of both interaction and solvation. We found that the source of the drug resistance is a decrease in the binding interaction combined with the reduction of the dehydration penalty. The smaller K292 mutated residue has a larger binding pocket cavity compared to the wild-type resulting in the loss of drug carboxylate-K292 hydrogen bonding and an increased accessibility for water molecules around the K292 mutated residue. In addition, oseltamivir does not bind well to the R292K mutant complex as shown by the high degree of fluctuation in ligand RMSD during the simulation and the change in angular distribution of bulky side chain groups. PMID- 27714496 TI - Community- and hospital-acquired infections with oseltamivir- and peramivir resistant influenza A(H1N1)pdm09 viruses during the 2015-2016 season in Japan. AB - We report five cases of community- and hospital-acquired infections with oseltamivir- and peramivir-resistant A(H1N1)pdm09 viruses possessing the neuraminidase (NA) H275Y mutation during January-February 2016 in Japan. One case was hospitalized and was receiving oseltamivir for prophylaxis. The remaining four cases were not taking antiviral drugs at the time of sampling. These cases were geographically distant and epidemiologically unrelated. The five viruses showed ~300-fold rise in IC50 values against oseltamivir and peramivir, defined as highly reduced inhibition according to the WHO definition. Overall, the prevalence of the H275Y A(H1N1)pdm09 viruses was 1.8 % (5/282). The resistant viruses possessed the V241I, N369 K, and N386 K substitutions in the NA that have been previously reported among A(H1N1)pdm09 to alter transmission fitness. Analysis of Michaelis constant (Km) revealed that two of the isolates had reduced NA affinity to MUNANA, while the other three isolates displayed a slightly decreased affinity compared to the sensitive viruses. Further studies are needed to monitor the community spread of resistant viruses and to assess their transmissibility. PMID- 27714497 TI - Mechanisms of ear trauma and reconstructive techniques in 105 consecutive patients. AB - Acquired auricular deformities may diminish facial esthetics and cause psychological distress. The aim of this article is to provide an overview of the type of injuries and applied reconstructive techniques in a large academic hospital in The Netherlands. A retrospective chart review was conducted for the last 105 patients who underwent auricular reconstruction for an acquired deformity. Data concerning gender, affected side, cause of injury, anatomical region, the previous and further surgeries, type of cartilage, and skin cover used were collected and analyzed. 105 patients were included. Acquired auricular deformities were mainly caused by bite injuries (22 %), traffic accidents (17 %), burns (9.5 %), and post-otoplasty complications (9.5 %). The upper third of the auricle was most often injured (41 %), followed by the entire auricle (19 %). 70 % of cases required reconstruction with costal cartilage. The most common form of cutaneous cover was a postauricular skin flap (40 % of cases). This study gives a complete overview of causes and treatment of acquired auricular deformities. The results are comparable with the results of similar studies found in literature. Bite wounds are the leading cause of acquired auricular injuries. The upper third is most commonly affected. In the largest percentage of reconstructions, costal cartilage and a postauricular flap were used to correct the deformity. PMID- 27714498 TI - Effect of a liposomal hyaluronic acid gel loaded with dexamethasone in a guinea pig model after manual or motorized cochlear implantation. AB - Goals of cochlear implantation have shifted from complete insertion of the cochlear electrode array towards low traumatic insertion with minimally invasive techniques. The aim of this study was first to evaluate, in a guinea pig model of cochlear implantation, the effect of a motorized insertion technique on hearing preservation. The second goal was to study a new gel formulation containing dexamethasone phosphate loaded in liposomes (DEX-P). Guinea pigs had a unilateral cochlear implantation with either a manual technique (n = 12), or a motorized technique (n = 15), with a 0.4 mm diameter and 4 mm long array trough a cochleostomy. At the end of the procedure, hyaluronic acid gel containing drug free liposomes, or liposomes loaded with DEX-P, was injected into the bulla. Auditory brainstem responses thresholds were recorded before surgery and day 2 and 7 after surgery. All the animals had increased auditory brainstem responses thresholds after the cochlear implantation. Implanted animals with the motorized insertion tool experienced a partial hearing recovery at day 7 but not in those implanted with the manual insertion procedure (p < 0.001). In the manually implanted animals, a partial recovery was observed when DEX-P contained in liposomal gel was locally administrated (p < 0.0001). Finally, no additive effect with the motorized insertion was noticed. The deleterious effect of manual insertion, during cochlear implantation, can be prevented with local DEX-P administration in the bulla at day 7. The use of a motorized tool performed more atraumatic electrode array insertion for postoperative hearing. PMID- 27714499 TI - Description of patients consulting the voice clinic regarding gender, age, occupational status, and diagnosis. AB - The purpose of this paper was to describe the gender, age, occupational status, and diagnosis of dysphonic patients. We retrospectively analyzed the medical records of 1079 patients examined at the Voice clinic of the University hospital of Liege in French-speaking Belgium. Overall, seven out of ten patients who attended the voice clinic for dysphonia were females. The patients' ages ranged from 4 to 93 (mean = 43.5). Females predominantly consulted at the age of 54 and males at the age of 9. Regarding the occupational status, workers represented more than half of our patients (53 %), while 11.2 % were unemployed, 15.4 % were students, and 19.9 % were retired. Regarding the diagnoses of the 1079 patients, nodules were the most common pathologies (n = 182, 16.9 % of the patients), prevailing in females (n = 142, 18.8 % of the females), and encountered in 16.8 % of the workers and 42.8 % of the students consulting the voice clinic. Following nodules, laryngeal mobility disorders were diagnosed in 16.4 % of the patients (n = 177), mainly females (n = 115), and was the most frequent diagnosis in retirees (n = 75, 34.9 %). The majority of the patients consulting the voice clinic for dysphonia were adult females, in their workforce, diagnosed with vocal nodules. The identification of the patients' characteristics and diagnoses is important to develop treatments and prevention of dysphonia, estimate their costs, and allow comparisons across referral centers. PMID- 27714500 TI - Astaxanthin supplementation attenuates immobilization-induced skeletal muscle fibrosis via suppression of oxidative stress. AB - Immobilization induces skeletal muscle fibrosis characterized by increasing collagen synthesis in the perimysium and endomysium. Transforming growth factor beta1 (TGF-beta1) is associated with this lesion via promoting differentiation of fibroblasts into myofibroblasts. In addition, reactive oxygen species (ROS) are shown to mediate TGF-beta1-induced fibrosis in tissues. These reports suggest the importance of ROS reduction for attenuating skeletal muscle fibrosis. Astaxanthin, a powerful antioxidant, has been shown to reduce ROS production in disused muscle. Therefore, we investigated the effects of astaxanthin supplementation on muscle fibrosis under immobilization. In the present study, immobilization increased the collagen fiber area, the expression levels of TGF beta1, alpha-smooth muscle actin, and superoxide dismutase-1 protein and ROS production. However, these changes induced by immobilization were attenuated by astaxanthin supplementation. These results indicate the effectiveness of astaxanthin supplementation on skeletal muscle fibrosis induced by ankle joint immobilization. PMID- 27714501 TI - IL28B rs12980275 and HLA rs4273729 genotypes as a powerful predictor factor for rapid, early, and sustained virologic response in patients with chronic hepatitis C. AB - Single-nucleotide polymorphisms (SNPs) in the Interleukin-28B (IL28B) gene and rs4273729 in the human leukocyte antigen (HLA) gene in chronic hepatitis C (CHC) virus infection are important for predicting treatment outcome. In this study, the distribution of IL28B SNPs (rs12979860 and rs12980275) and HLA rs4273729 in rapid virologic response (RVR), complete early virologic response (cEVR) and sustained virologic response (SVR) in HCV Iranian patients with CHC virus infection was assessed. IL28B genotyping and rs4273729 were performed using the amplification refractory mutation system (ARMS)-PCR and direct sequencing in 190 CHC virus infections, respectively. RVR, cEVR, and SVR were 53.2 %, 78.9 %, and 65.8 %, respectively. Multivariate regression analysis demonstrated that the responses significantly predicted SVR in patients with age <40 years (p = 0.008), HCV genotypes (p = 0.032), IL28B rs12979860 CC genotype (p < 0.001), rs12980275 AA genotype (p < 0.001), rs4273729 GG genotype (p < 0.001), RVR (p < 0.001) and cEVR (p = 0.024). Three critical predictor factors based on RVR response were rs12979860 CC genotype (p = 0.033), rs12980275 AA genotype (p < 0.001) and rs4273729 GG genotype (p < 0.001), while rs12980275 AA (p = 0.003) and rs4273729 GG genotypes (p < 0.001) predicted cEVR. For the first time in Iran, these results revealed that the rs12980275 and HLA rs4273729 are important for the treatment of CHC infection. These findings may help predict responses to CHC infection treatment and reduce the cost and side effects of therapy. PMID- 27714502 TI - Development of an updated PCR assay for detection of African swine fever virus. AB - Due to the current unavailability of vaccines or treatments for African swine fever (ASF), which is caused by African swine fever virus (ASFV), rapid and reliable detection of the virus is essential for timely implementation of emergency control measures and differentiation of ASF from other swine diseases with similar clinical presentations. Here, an improved PCR assay was developed and evaluated for sensitive and universal detection of ASFV. Primers specific for ASFV were designed based on the highly conserved region of the vp72 gene sequences of all ASFV strains available in GenBank, and the PCR assay was established and compared with two OIE-validated PCR tests. The analytic detection limit of the PCR assay was 60 DNA copies per reaction. No amplification signal was observed for several other porcine viruses. The novel PCR assay was more sensitive than two OIE-validated PCR assays when testing 14 strains of ASFV representing four genotypes (I, V, VIII and IX) from diverse geographical areas. A total of 62 clinical swine blood samples collected from Uganda were examined by the novel PCR, giving a high agreement (59/62) with a superior sensitive universal probe library-based real-time PCR. Eight out of 62 samples tested positive, and three samples with higher Ct values (39.15, 38.39 and 37.41) in the real-time PCR were negative for ASFV in the novel PCR. In contrast, one (with a Ct value of 29.75 by the real-time PCR) and two (with Ct values of 29.75 and 33.12) ASFV-positive samples were not identified by the two OIE-validated PCR assays, respectively. Taken together, these data show that the novel PCR assay is specific, sensitive, and applicable for molecular diagnosis and surveillance of ASF.

AB - Severe influenza is characterized by a cytokine storm, and the influenza virus cytokine-trypsin cycle is one of the important mechanisms of viral multiplication and multiple organ failure. The aim of this study was to define the key cytokine(s) responsible for trypsin upregulation. Mice were infected with influenza virus strain A/Puerto Rico/8/34 (H1N1) or treated individually or with a combination of interleukin-1beta, interleukin-6, and tumor necrosis factor alpha. The levels of these cytokines and trypsin in the lungs were monitored. The neutralizing effects of anti-IL-1beta antibodies on cytokine and trypsin expression in human A549 cells and lung inflammation in the infected mice were examined. Infection induced interleukin-1beta, interleukin-6, tumor necrosis factor alpha, and ectopic trypsin in mouse lungs in a dose- and time-dependent manner. Intraperitoneal administration of interleukin-1beta combined with other cytokines tended to upregulate trypsin and cytokine expression in the lungs, but the combination without interleukin-1beta did not induce trypsin. In contrast, incubation of A549 cells with interleukin-1beta alone induced both cytokines and trypsin, and anti-interleukin-1beta antibody treatment abrogated these effects. Administration of the antibody in the infected mice reduced lung inflammation area. These findings suggest that IL-1beta plays a key role in trypsin upregulation and has a pathological role in multiple organ failure. PMID- 27714504 TI - Diabetic charcot neuroarthropathy: prevalence, demographics and outcome in a regional referral centre. AB - BACKGROUND: Diabetic Charcot neuroarthropathy (DCN) is a devastating complication for people with diabetes mellitus. The failure to diagnose DCN and institute treatment in the acute phase leads to permanent deformity and significant morbidity. There is a paucity of data on the prevalence and characteristics of patients who have developed this complication of diabetes. AIMS: To determine the prevalence, clinical characteristics and outcomes of patients with DCN from 2006 to 2012. METHODS: Case finding was performed by searching three independent lists for the period 2006-2012 including: SYNGO radiology database, HIPE database of hospital discharges, and, combined list from podiatry, endocrinology, vascular surgery and orthopaedic clinics. A consensus meeting with chart review was undertaken to confirm diagnosis of DCN. A proforma was completed from chart review to determine clinical characteristics, initial treatment and outcomes for patients with DCN. RESULTS: Forty cases of DCN were identified, resulting in an estimated period prevalence of 0.3 %. The majority of patients were male (68 %); most patients had T2DM (73 %). Mean +/- SD for age was 58 +/- 10 years and mean duration of diabetes was 15 +/- 9 years. In the acute phase of DCN, offloading was performed in 50 %. Bisphosphonates were administered to 5 % and surgery undertaken in 5 % of cases. 38 % of patients developed subsequent foot ulceration and 20 % required amputation. CONCLUSIONS: This is the first prevalence estimate of DCN in Ireland. These data suggest diagnosis of DCN is missed in the acute phase. There exists a significant risk of diabetic foot ulceration and amputation with DCN. PMID- 27714505 TI - Grapevine phenology and climate change in Georgia. AB - While the climate of Western Europe has been deeply affected by the abrupt climate change that took place in the late '1980s of the twentieth century, a similar signal is detected only few years later, in 1994, in Georgia. Grapevine phenology is deeply influenced by climate and this paper aimed to analyze how phenological timing changed before and after the climatic change of 1994. Availability of thermal resources in the two climatic phases for the five altitudinal belts in the 0-1250-m range was analyzed. A phenological dataset gathered in two experimental sites during the period 2012-2014, and a suitable thermal dataset was used to calibrate a phenological model based on the normal approach and able to describe BBCH phenological stages 61 (beginning of flowering), 71 (fruit set), and 81 (veraison). Calibration was performed for four relevant Georgian varieties (Mtsvane Kakhuri, Rkatsiteli, Ojaleshi, and Saperavi). The model validation was performed on an independent 3-year dataset gathered in Gorizia (Italy). Furthermore, in the case of variety Rkatsiteli, the model was applied to the 1974-2013 thermal time series in order to obtain phenological maps of the Georgian territory. Results show that after the climate change of 1994, Rkatsiteli showed an advance, more relevant at higher altitudes where the whole increase of thermal resource was effectively translated in phenological advance. For instance the average advance of veraison was 5.9 days for 250-500 m asl belt and 18.1 days for 750-1000 m asl). On the other hand, at lower altitudes, phenological advance was depleted by superoptimal temperatures. As a final result, some suggestions for the adaptation of viticultural practices to the current climatic phase are provided.

AB - This study aims to compare the effects of balneological treatments applied at consecutive and intermittent sessions without interfering with their daily routine in patients with knee osteoarthritis. This is a randomized, controlled, single-blind clinical trial. Fifty patients diagnosed with knee osteoarthritis were included. The patients were divided into two groups. All patients were given a total of ten sessions of balneological treatment consisting of hydrotherapy and mud pack therapy. Group 1 received consecutive treatment for 2 weeks, while group 2 received intermittent treatment for 5 weeks. Local peloid packs at 45 degrees C were applied for 20 min, after a tap water (38 degrees C) bath. Evaluations were conducted before, after treatment, and at 12th week of post-treatment by Pain (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Short Form-36 (SF-36). Both balneological treatment regimens of knee osteoarthritis had statistically significant clinical effects as well as effects on the quality of life. Patients' well-being continued at 3 months, except for joint stiffness (WOMAC), role-emotional (SF-36), and vitality (SF-36) in group 1 and for mental health (SF-36) in both groups. Both patient groups had improved compared to baseline. However, at 3 months after the treatment, the well-being of group 2 was unable to be maintained in terms of role-physical (SF-36) parameter, while the well-being of group 1 was unable to be maintained in terms of pain, WOMAC (pain, physical functions, total), and SF-36 (physical functioning, role physical, pain, role-emotional, and mental health) variables, compared to data obtained immediately after treatment. Our study suggests that traditional and intermittent balneological therapies have similar efficacy in patients with knee osteoarthritis. PMID- 27714507 TI - NMR assignments of the GacS histidine-kinase periplasmic detection domain from Pseudomonas aeruginosa PAO1. AB - Pseudomonas aeruginosa is a highly adaptable opportunistic pathogen. It can infect vulnerable patients such as those with cystic fibrosis or hospitalized in intensive care units where it is responsible for both acute and chronic infection. The switch between these infections is controlled by a complex regulatory system involving the central GacS/GacA two-component system that activates the production of two small non-coding RNAs. GacS is a histidine kinase harboring one periplasmic detection domain, two inner-membrane helices and three H1/D1/H2 cytoplasmic domains. By detecting a yet unknown signal, the GacS histidine-kinase periplasmic detection domain (GacSp) is predicted to play a key role in activating the GacS/GacA pathway. Here, we present the chemical shift assignment of 96 % of backbone atoms (HN, N, C, Calpha, Cbeta and Halpha), 88 % aliphatic hydrogen atoms and 90 % of aliphatic carbon atoms of this domain. The NMR-chemical shift data, on the basis of Talos server secondary structure predictions, reveal that GacSp consists of 3 beta-strands, 3 alpha-helices and a major loop devoid of secondary structures.

PMID- 27714511 TI - Interventional EUS Using a Flexible 19-Gauge Needle: An International Multicenter Experience in 162 Patients. AB - BACKGROUND AND AIMS: To facilitate access for interventional EUS, flexible (nitinol) 19-G needles have been introduced to permit needle puncture even when the echoendoscope is in an angulated position, such as in the second part of the duodenum. The aims of the study were to evaluate the performance of a flexible 19 G needle during interventional EUS procedures and compare outcomes when the echoendoscope was in the straight versus angulated position. METHODS: A retrospective review was undertaken of 162 consecutive patients that underwent a variety of interventional EUS procedures with a flexible 19-G needle across five centers. Patients were subdivided into categories (straight or angulated) depending on the echoendoscope position used for obtaining access to the area of interest (Fig. 1). Fig. 1 Flexible 19-G needle design. a The needle is able to exit the sheath despite the rotated position. b The needle beveled needle tip RESULTS: In the entire cohort, needle-specific technical success was achieved in 93.2 %, procedural success in 85.2 %, and overall clinical success in 76.5 % of cases at a mean follow-up of 3.1 months. Needle-specific technical success was similar between the straight and angulated cohorts (94.0 vs. 91.2 %, p = 0.74). Procedural success (86.7 vs. 77.2 %, p = 0.05), and rate of clinical success was similar between the cohorts (83.3 vs. 86.4 %, p = 0.79), respectively. Overall adverse events were noted in 14.2 % of patients with no difference between the straight and angulated cohorts (p = 0.48). CONCLUSIONS: This study demonstrates equivalent technical success, clinical success and safety of using a flexible 19 G needle in straight and angulated endoscope positions for interventional EUS. Therefore, a flexible needle may be considered where an angulated echoendoscope position is encountered. PMID- 27714512 TI - Optic disc tilt direction affects regional visual field progression rates in myopic eyes with open-angle glaucoma. AB - PURPOSE: To compare global and regional visual field (VF) progression rates and determine clinical factors associated with rapid VF progression in myopic patients with open-angle glaucoma (OAG) with different disc tilt directions. METHODS: The medical records of 182 eyes from 182 myopic OAG patients with progressive VF deterioration during follow-up were analyzed. The rates of change in the mean thresholds of the global and regional VF areas of the horizontal and vertical disc tilt (HDT and VDT) groups were compared using a linear mixed model after controlling for confounding covariates. Clinical factors associated with rapid VF progression in global and regional VF areas were investigated. RESULTS: The VDT group showed significantly faster VF progression at inferior regional zones than the HDT group (P < 0.05). Based on a multivariate linear mixed model, VDT was associated with faster bi-hemifield VF progression in the GHT map, whereas HDT was associated with faster single-hemifield VF progression. CONCLUSIONS: Myopic OAG eyes show significantly different regional VF progression rates according to disc tilt direction. VDT is an independent predictor of a rapid rate of regional VF progression in both hemifields, whereas HDT predicts rapid regional VF progression in a single hemifield. PMID- 27714510 TI - Cardiovascular Risk Reduction in Patients with Nonalcoholic Fatty Liver Disease: The Potential Role of Ezetimibe. AB - Nonalcoholic fatty liver disease (NAFLD) is widely considered to be the hepatic manifestation of the metabolic syndrome and is closely linked to dyslipidemia, obesity, and insulin resistance. Patients with NAFLD have increased mortality when compared to the general population, primarily related to cardiovascular disease or malignancy. The biologic mechanisms that link NAFLD to cardiovascular disease include expansion of visceral adipose tissue, atherogenic dyslipidemia, impaired insulin signaling, systemic inflammation, and endothelial dysfunction. Currently, there are no approved therapies for NAFLD. It has recently been hypothesized that reducing the delivery of dietary cholesterol using the hypolipidemic agent, ezetimibe, could benefit patients with NAFLD. By potently inhibiting the Niemann-Pick C1-Like 1 (NPC1L1) sterol receptor on intestinal enterocytes and within the liver, ezetimibe blocks exogenous cholesterol absorption and has been shown to improve biochemical markers of NAFLD, improve insulin sensitivity and decrease hepatic steatosis. This review summarizes the clinical and epidemiological evidence for the relationship between NAFLD and cardiovascular risk and examines the potential therapeutic role of ezetimibe. PMID- 27714513 TI - Comparison of two individualized treatment regimens with ranibizumab for diabetic macular edema. AB - PURPOSE: To compare outcomes between an as-needed and a treat-and-extend regimen in managing diabetic macular edema with intravitreal ranibizumab. METHODS: This was a retrospective, single-centre, comparative case series on 46 treatment naive patients with diabetic macular edema. Twenty-two patients were treated following an optical coherence tomography guided treat-and-extend protocol (OCTER), and 24 patients were treated according to a visual acuity guided pro re nata regimen (VAPRN) at a tertiarry referral centre. The main outcome measures were best corrected visual acuity, central retinal thickness, and the number of ranibizumab injections, as well as visits after 12 months of treatment. RESULTS: After 12 months, the mean gain in best-corrected visual acuity (+/- standard deviation) was 8.3 +/- 6.7 versus 9.3 +/- 8.9 letters in the VAPRN and OCTER group, respectively (p = 0.3). The mean decrease in central retinal thickness was 68.1 +/- 88.0 MUm in the VAPRN group and 117.6 +/- 114.4 MUm in the OCTER group (p = 0.2). The mean number of ranibizumab injections was significantly different between the VAPRN (5.9 +/- 1.8) and the OCTER protocol (8.9 +/- 2.0) (p < 0.001). CONCLUSION: The visual acuity driven retreatment regimen resulted in a similar visual acuity outcome like optical coherence tomography guided retreatment for diabetic macular edema. Although the number of visits was similar in both groups, patients in the VAPRN group received significantly fewer intravitreal injections than patients in the OCTER group. PMID- 27714514 TI - Hippocampal GluA2 and GluA4 protein but not corresponding mRNA and promoter methylation levels are modulated at retrieval in spatial learning of the rat. AB - AMPA receptors mediate most fast excitatory synaptic transmission in the brain. Highly dynamic AMPA receptors are subjected to trafficking, recycling, and/or degradation and replacement. Changes in AMPA receptor abundance is an important mechanism involved in learning and memory formation. Results obtained with the Morris water maze (MWM), a paradigm for testing spatial memory in rodent, correlate with hippocampal synaptic plasticity and NMDA function. Different phases of spatial learning like acquisition and retrieval involve AMPA receptors. Long-term memory formation requires dynamic changes in gene transcription and protein synthesis. It is, however, not known so far if epigenetic marks such as DNA methylation and mRNA levels participate in regulation of AMPA receptors in hippocampus during memory retrieval. In the present study, rats were trained or untrained in the MWM. Steady state levels of hippocampal GluA1-4 mRNA were determined by RT-PCR and promoter methylation levels of GluA1-4 by in-house developed bisulfite pyrosequencing methods. GluA1-4 protein levels were determined in parallel in a membrane fraction by SDS-PAGE followed by Western blotting. Our results indicate that changes of hippocampal membrane AMPA receptors were modulated at the protein level, while no changes were observed at the mRNA and at the promoter methylation level of hippocampal GluA1-4. Training in the MWM at retrieval may, therefore, involve GluA2 and GluA4 subunits that may be regulated by protein stability or trafficking as protein determinations were carried out in a hippocampal membrane fraction. PMID- 27714516 TI - Role of amino acid residues surrounding the phosphorylation site in peptide substrates of G protein-coupled receptor kinase 2 (GRK2). AB - A series of amino acid substitutions was made in a previously identified beta tubulin-derived GRK2 substrate peptide (404DEMEFTEAESNMN416) to examine the role of amino acid residues surrounding the phosphorylation site. Anionic amino acid residues surrounding the phosphorylation site played an important role in the affinity for GRK2. Compared to the original peptide, a modified peptide (Ac EEMEFSEAEANMN-NH2) exhibited markedly higher affinity for GRK2, but very low affinity for GRK5, suggesting that it can be a sensitive and selective peptide for GRK2. PMID- 27714515 TI - Human splanchnic amino-acid metabolism. AB - Plasma levels of several amino acids are correlated with metabolic dysregulation in obesity and type 2 diabetes. To increase our understanding of human amino-acid metabolism, we aimed to determine splanchnic interorgan amino-acid handling. Twenty patients planned to undergo a pylorus preserving pancreatico-duodenectomy were included in this study. Blood was sampled from the portal vein, hepatic vein, superior mesenteric vein, inferior mesenteric vein, splenic vein, renal vein, and the radial artery during surgery. The difference between arterial and venous concentrations of 21 amino acids was determined using liquid chromatography as a measure of amino-acid metabolism across a given organ. Whereas glutamine was significantly taken up by the small intestine (121.0 +/- 23.8 umol/L; P < 0.0001), citrulline was released (-36.1 +/- 4.6 umol/L; P < 0.0001). This, however, was not seen for the colon. Interestingly, the liver showed a small, but a significant uptake of citrulline from the circulation (4.8 +/- 1.6 umol/L; P = 0.0138) next to many other amino acids. The kidneys showed a marked release of serine and alanine into the circulation (-58.0 +/- 4.4 umol/L and -61.8 +/- 5.2 umol/L, P < 0.0001), and a smaller, but statistically significant release of tyrosine (-12.0 +/- 1.3 umol/L, P < 0.0001). The spleen only released taurine (-9.6 +/- 3.3 umol/L; P = 0.0078). Simultaneous blood sampling in different veins provides unique qualitative and quantitative information on integrative amino-acid physiology, and reveals that the well-known intestinal glutamine-citrulline pathway appears to be functional in the small intestine but not in the colon. PMID- 27714517 TI - Learning curve in robotic rectal cancer surgery: current state of affairs. AB - INTRODUCTION: Robotic-assisted rectal cancer surgery offers multiple advantages for surgeons, and it seems to yield the same clinical outcomes as regards the short-time follow-up of patients compared to conventional laparoscopy. This surgical approach emerges as a technique aiming at overcoming the limitations posed by rectal cancer and other surgical fields of difficult access, in order to obtain better outcomes and a shorter learning curve. MATERIAL AND METHODS: A systematic review of the literature of robot-assisted rectal surgery was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) statement. The search was conducted in October 2015 in PubMed, MEDLINE and the Cochrane Central Register of Controlled Trials, for articles published in the last 10 years and pertaining the learning curve of robotic surgery for colorectal cancer. It consisted of the following key words: "rectal cancer/learning curve/robotic-assisted laparoscopic surgery". RESULTS: A total of 34 references were identified, but only 9 full texts specifically addressed the analysis of the learning curve in robot-assisted rectal cancer surgery, 7 were case series and 2 were non-randomised case-comparison series. Eight papers used the cumulative sum (CUSUM) method, and only one author divided the series into two groups to compare both. The mean number of cases for phase I of the learning curve was calculated to be 29.7 patients; phase II corresponds to a mean number 37.4 patients. The mean number of cases required for the surgeon to be classed as an expert in robotic surgery was calculated to be 39 patients. CONCLUSION: Robotic advantages could have an impact on learning curve for rectal cancer and lower the number of cases that are necessary for rectal resections. PMID- 27714518 TI - Laparoscopic complete mesocolic excision for right-sided colon cancer using a cranial approach: anatomical and embryological consideration. AB - BACKGROUND: Complete mesocolic excision (CME) with central vascular ligation (CVL) should be employed for the treatment of colon cancer patients because of its superior oncological outcomes. However, this technique is technically challenging in laparoscopic right hemicolectomy because of the anatomical complexity of the transverse mesocolon. METHODS: We focused on the embryology and anatomy of the transverse mesocolon to overcome the difficulty of this surgery. The validity and efficacy of a cranial approach in achieving CME with CVL in laparoscopic right hemicolectomy was elucidated from the embryological point of view. RESULTS: In total, 28 consecutive patients with right-sided colon cancer were treated by laparoscopic right hemicolectomy using a cranial approach. There were no conversion to open surgery or switching to another approach. Using this approach, torsion and fusion of the transverse mesocolon, which occurred during embryological development, could be reversed and the complex anatomy of the transverse mesocolon could be simplified before performing CVL of colonic vessels. CONCLUSIONS: A cranial approach is considered valid and useful for CME with CVL in laparoscopic right hemicolectomy from the embryological point of view.

PMID- 27714520 TI - The use of transureteroureterostomy during ureteral reconstruction for advanced primary or recurrent pelvic malignancy in the era of multimodal therapy. AB - PURPOSE: Cancerous involvement of a ureter is sometimes encountered in pelvic surgery for malignancy. We usually perform transureteroureterostomy (TUU) in cases of unilateral lower ureteral cancerous involvement. We report the outcomes in patients treated with TUU in our institute. METHODS: We retrospectively reviewed the medical records of 11 patients who underwent TUU between June 2006 and September 2015. RESULTS: The primary disease was colon cancer in five patients, rectal cancer in four, and uterine cervical cancer and ovarian cancer in one patient each. Early postoperative complications relevant to TUU occurred in four patients; however, three patients were managed conservatively and recovered quickly. Only one patient developed ureteral obstruction, which resulted from anastomotic hematoma. Follow-up periods ranged from 5 to 78 months with a median of 28 months. The median estimated glomerular filtration rate before and after TUU was 59 ml/min (range, 31-90 ml/min) and 62.0 ml/min (range, 43-127 mL/min), respectively. No patients experienced worsening of their renal function or recurrent urinary tract infection. CONCLUSIONS: Short-term outcomes are good and long-term renal function is maintained following TUU. TUU is considered a feasible technique for ureteral reconstruction for pelvic malignancy, and TUU has great potential in the era of multimodal therapy. PMID- 27714521 TI - Prospective multicenter registration study of colorectal cancer: significant variations in radicality and oncosurgical quality-Swiss Group for Clinical Cancer Research Protocol SAKK 40/00. AB - PURPOSE: This study aimed to investigate in a multicenter cohort study the radicality of colorectal cancer resections, to assess the oncosurgical quality of colorectal specimens, and to compare the performance between centers. METHODS: One German and nine Swiss hospitals agreed to prospectively register all patients with primary colorectal cancer resected between September 2001 and June 2005. The median number of eligible patients with one primary tumor included per center was 95 (range 12-204). RESULTS: The following variations of median values or percentages between centers were found: length of bowel specimen 20-39 cm (25.8 cm), maximum height of mesocolon 6.5-12.5 cm (9.0 cm), number of examined lymph nodes 9-24 (16), distance to nearer bowel resection margin in colon cancer 4.8-12 cm (7 cm), and in rectal cancer 2-3 cm (2.5 cm), central ligation of major artery 40-97 % (71 %), blood loss 200-500 ml (300 ml), need for perioperative blood transfusion 5-40 % (19 %), tumor opened during mobilization 0-11 % (5 %), T4 tumors not en-bloc resected 0-33 % (4 %), inadvertent perforation of mesocolon/mesorectum 0-8 % (4 %), no-touch isolation technique 36-86 % (67 %), abdominoperineal resection for rectal cancer 0-30 % (17 %), rectal cancer specimen with circumferential margin <=1 mm 0-19 % (10 %), in-hospital mortality 0-6 % (2 %), anastomotic leak or intra-abdominal abscess 0-17 % (7 %), re operation 0-17 % (8 %). CONCLUSION: In colorectal cancer, surgery considerable variations between different centers were found with regard to radicality and oncosurgical quality, suggesting a potential for targeted improvement of surgical technique. PMID- 27714522 TI - Factors Associated with Health Information Seeking, Processing, and Use Among HIV Positive Adults in the Dominican Republic. AB - Effective treatment and management of human immunodeficiency virus (HIV) depend on patients' ability to locate, comprehend, and apply health information. This study's purpose was to identify characteristics associated with these skills among HIV positive adults in the Dominican Republic. An information behavior survey was administered to 107 participants then three logistic regressions were conducted to identify characteristics associated with information seeking, processing, and use. Never having cared for someone who was sick was significantly associated with less information seeking, processing, and use. Males were more likely to be active information seekers and those who had attended the clinic for six or fewer years were less likely to actively seek information. Younger individuals had increased odds of higher information processing and those without comorbidities had increased odds of more information use. Results may inform researchers, organizations, and providers about how patients interact with health information in limited resource settings.

AB - Once facing the most severe HIV epidemic in Eastern Europe, Ukraine has built an elaborate Monitoring and Evaluation (M&E) system to track the response to AIDS. This system was developed using recommendations and input from multiple international expert organizations and donors and, at the current stage, serves as a best practice model in many areas. The present paper aims to provide a comprehensive overview of the evolution of the M&E system in Ukraine since its inception. Notable achievements and challenges are described and illustrated by epidemiological data and the recommendations for future development are discussed. Unique experiences and advances in M&E in Ukraine may be useful to other countries facing similar epidemiological, structural or methodological issues. PMID- 27714523 TI - Two-Year Trajectories of Sexual Risk Behaviors Among Drug-Using Adolescents and Emerging Adults in an Urban Community. AB - Among 14-24 year-olds who used drugs and were recruited from an emergency department, we examined 2-year trajectories of sexual risk behaviors. We hypothesized that those in higher risk trajectories would have more severe substance use, mental health concerns, and dating violence involvement at baseline. Analyses identified three behavioral trajectories. Individuals in the highest risk trajectory had a more severe profile of baseline alcohol use, marijuana use, dating violence involvement, and mental health problems. Future research will examine longitudinal differences in risk factors across trajectories. Understanding risk factors for sexual risk behavior trajectories can inform the delivery and tailoring of prevention interventions. PMID- 27714525 TI - A Comparison of Adherence Timeframes Using Missed Dose Items and Their Associations with Viral Load in Routine Clinical Care: Is Longer Better? AB - Questions remain regarding optimal timeframes for asking about adherence in clinical care. We compared 4-, 7-, 14-, 30-, and 60-day timeframe missed dose items with viral load levels among 1099 patients on antiretroviral therapy in routine care. We conducted logistic and linear regression analyses examining associations between different timeframes and viral load using Bayesian model averaging (BMA). We conducted sensitivity analyses with subgroups at increased risk for suboptimal adherence (e.g. patients with depression, substance use). The 14-day timeframe had the largest mean difference in adherence levels among those with detectable and undetectable viral loads. BMA estimates suggested the 14-day timeframe was strongest overall and for most subgroups although findings differed somewhat for hazardous alcohol users and those with current depression. Adherence measured by all missed dose timeframes correlated with viral load. Adherence calculated from intermediate timeframes (e.g. 14-day) appeared best able to capture adherence behavior as measured by viral load. PMID- 27714526 TI - The Effectiveness and Safety of Sleeve Gastrectomy in the Obese Elderly Patients: a Systematic Review and Meta-Analysis. AB - BACKGROUND: This systematic review was performed to compare the effectiveness and safety of SG in the obese elderly patients with the young ones. METHODS: Cohort studies that compared outcomes among old and young patients who had undergone SG were included. Summary odds ratios were estimated using a random effect model. RESULTS: Eleven studies were included. Old patients had a worse outcome in percentage of excess weight loss than the young ones (SMD -0.39, 95 % CI -0.55 to -0.24). No significant differences were recorded in resolution of co-morbidities: type 2 diabetes mellitus (OR 1.60, 95 % CI 0.84-3.05), hypertension (OR 1.05, 95 % CI 0.65-1.68), dyslipidemia (OR 1.38, 95 % CI 0.68-2.80), OSAS (OR 0.64, 95 % CI 0.30-1.34), or postoperative complications (OR 0.89, 95 % CI 0.51-1.55) between the elderly and the young who had undergone SG. CONCLUSIONS: SG was effective for weight loss and resolution of co-morbidities with low complication rate in the obese elderly patients. PMID- 27714527 TI - Banded Gastric Bypass: Better Long-Term Results? A Cohort Study with Minimum 5 Year Follow-Up. AB - BACKGROUND: While gastric bypass has been the treatment of choice for morbid obesity, insufficient weight loss and even weight regain has been observed in a sub-group of patients. Dilatation of the pouch, pouch outlet, and proximal alimentary limb have been suggested to cause weight regain on the long term. The banded gastric bypass surgery has been introduced to overcome this problem. METHODS: Four hundred thirty-two patients (n = 254, non-banded/n = 178, banded GaBP RingTM) were followed-up for 5 years. Patients were evaluated for weight loss, % excess weight loss (%EWL), weight regain and BMI. RESULTS: No significant differences between groups in the first year following surgery were observed in terms of weight loss and %EWL. %EWL at 5 years was as follows: non-banded 65.2 +/ 20.0 %; banded 74.0 +/- 15.1 %. At 5 years, the banded group showed more weight loss (non-banded 35.4 +/- 12.5; banded 43.9 +/- 11.9 kg, P < 0.0001); weight regain was significantly higher in the non-banded group (P < 0.0001). Only minor complications were reported; no signs of ring migration or slippage were reported. CONCLUSION: Although, following the first year after surgery, no differences in treatment groups were observed in terms of weight loss, 5 years following surgery, patients who received banded surgery maintained better weight loss and had less weight regain compared to the non-banded group. These results suggest that laparoscopic banded gastric bypass using a silastic ring was effective in maintaining weight loss on the long term, while the complication rate was low. The banded gastric bypass is regarded by us as the new gold standard. PMID- 27714528 TI - Adhesion of multimode adhesives to enamel and dentin after one year of water storage. AB - OBJECTIVES: This study aimed to evaluate the ultramorphological characteristics of tooth-resin interfaces and the bond strength (BS) of multimode adhesive systems to enamel and dentin. METHODS: Multimode adhesives (Scotchbond Universal (SBU) and All-Bond Universal) were tested in both self-etch and etch-and-rinse modes and compared to control groups (Optibond FL and Clearfil SE Bond (CSB)). Adhesives were applied to human molars and composite blocks were incrementally built up. Teeth were sectioned to obtain specimens for microtensile BS and TEM analysis. Specimens were tested after storage for either 24 h or 1 year. SEM analyses were performed to classify the failure pattern of beam specimens after BS testing. RESULTS: Etching increased the enamel BS of multimode adhesives; however, BS decreased after storage for 1 year. No significant differences in dentin BS were noted between multimode and control in either evaluation period. Storage for 1 year only reduced the dentin BS for SBU in self-etch mode. TEM analysis identified hybridization and interaction zones in dentin and enamel for all adhesives. Silver impregnation was detected on dentin-resin interfaces after storage of specimens for 1 year only with the SBU and CSB. CONCLUSIONS: Storage for 1 year reduced enamel BS when adhesives are applied on etched surface; however, BS of multimode adhesives did not differ from those of the control group. In dentin, no significant difference was noted between the multimode and control group adhesives, regardless of etching mode. CLINICAL RELEVANCE: In general, multimode adhesives showed similar behavior when compared to traditional adhesive techniques. Multimode adhesives are one-step self-etching adhesives that can also be used after enamel/dentin phosphoric acid etching, but each product may work better in specific conditions.

AB - The claustrum is a brain region whose function remains unknown, though many investigators suggest it plays a role in conscious attention. Resting-state functional magnetic resonance imaging (RS-fMRI) has revealed how anesthesia alters many functional connections in the brain, but the functional role of the claustrum with respect to the awake versus anesthetized states remains unknown. Therefore, we employed a combination of seed-based RS-fMRI and neuroanatomical tracing to reveal how the anatomical connections of the claustrum are related to its functional connectivity during quiet wakefulness and the isoflurane-induced anesthetic state. In awake rats, RS-fMRI indicates that the claustrum has interhemispheric functional connections with the mediodorsal thalamus (MD) and medial prefrontal cortex (mPFC), as well as other known connections with cortical areas that correspond to the connections revealed by neuroanatomical tracing. During deep isoflurane anesthesia, the functional connections of the claustrum with mPFC and MD were significantly attenuated, while those with the rest of cortex were not significantly altered. These changes in claustral functional connectivity were also observed when seeds were placed in mPFC or MD during RS fMRI comparisons of the awake and deeply anesthetized states. Collectively, these data indicate that the claustrum has functional connections with mPFC and MD thalamus that are significantly lessened by anesthesia.

AB - PURPOSE: The purpose of this study is to determine the efficacy of ginger for reducing chemotherapy-induced nausea and vomiting (CINV) in breast cancer patients receiving adriamycin and cyclophosphamide (AC) regimens. METHODS: We enrolled breast cancer patients receiving AC who experienced moderate to severe nausea or vomiting during the first chemotherapy cycle. Subjects were randomized to receive a 500-mg ginger capsule or placebo twice a day for 5 days starting on the first day of the second AC cycle and were switched to the other treatment in the third cycle. All participants also received ondansetron and dexamethasone for CINV prophylaxis. Nausea severity was recorded once a day during the first 5 days of each cycle. The primary outcome was reduction in nausea score. RESULTS: Thirty four subjects (68 cycles of AC) were enrolled. Mean (range) maximum nausea score in the first AC cycle was 58 (40-90). Thirty-three subjects (97 %) received the same AC doses in the second as in the third cycle. Mean (+/-standard error) maximum nausea scores in patients receiving ginger and placebo were 35.36 (+/ 4.43) and 32.17 (+/-3.71), respectively. The difference in mean maximum nausea scores was 3 (95 % confidence interval, -3 to 9; P = 0.3). There were no significant differences between ginger and placebo in terms of vomiting incidence and severity, rescue medication use, chemotherapy compliance, and adverse events. CONCLUSIONS: Ginger (500 mg) twice daily was safe, but conferred no additional benefit in terms of reducing nausea severity in breast cancer patients receiving AC and ondansetron and dexamethasone for CINV prophylaxis. PMID- 27714531 TI - Unequal cancer survivorship care: addressing cultural and sociodemographic disparities in the clinic. AB - The number of individuals diagnosed with cancer is growing worldwide. Cancer patients from underserved populations have widely documented disparities through the continuum of cancer care. As the number of cancer survivors (i.e., individuals who have completed cancer treatment) from underserved populations also continue to grow, these individuals may continue to experience barriers to survivorship care, resulting in persistent long-term negative impacts on health and quality of life. In addition, there is limited participation of survivors from underserved populations in clinical trials and other research studies. To address disparities and change practices in survivorship care, a better understanding of the roles of both socioeconomic status (SES) and of culture in cancer care disparities and the relevance of these to providing high-quality care is needed. SES and culture often overlap but are not identical; understanding the impact of each is especially relevant to survivorship care. To enhance health equity among cancer survivors, clinicians need to practice culturally competent care, address cultural beliefs and practices that may influence survivors' beliefs and activities, gain awareness of historical patterns of medical care in the survivor's community, and consider how barriers to cross-cultural communications may hinder communication in clinical settings. While the design and implementation of survivorship care programs emphasizing effectiveness and equity is complex and potentially time consuming, it is critical for providing optimal care for all survivors, including those from the most vulnerable populations. PMID- 27714532 TI - Determining best methods to screen for religious/spiritual distress. AB - PURPOSE: This study sought to validate for the first time a brief screening measure for religious/spiritual (R/S) distress given the Commission on Cancer's mandated screening for psychosocial distress including spiritual distress. METHODS: Data were collected in conjunction with an annual survey of adult hematopoietic cell transplantation (HCT) survivors. Six R/S distress screeners were compared to the Brief RCOPE, Negative Religious Coping subscale as the reference standard. We pre-specified validity as a sensitivity score of at least 85 %. As no individual measure attained this, two post hoc analyses were conducted: analysis of participants within 2 years of transplantation and of a simultaneous pairing of items. Data were analyzed from 1449 respondents whose time since HCT was 6 months to 40 years. RESULTS: For the various single-item screening protocols, sensitivity ranged from 27 (spiritual/religious concerns) to 60 % (meaning/joy) in the full sample and 25 (spiritual/religious concerns) to 65 % (meaning/joy) in a subsample of those within 2 years of HCT. The paired items of low meaning/joy and self-described R/S struggle attained a net sensitivity of 82 % in the full sample and of 87 % in those within 2 years of HCT but with low net specificities. CONCLUSIONS: While no single-item screener was acceptable using our pre-specified sensitivity value of 85 %, the simultaneous use of meaning/joy and self-described struggle items among cancer survivors is currently the best choice to briefly screen for R/S distress. Future research should validate this and other approaches in active treatment cancer patients and survivors and determine the best times to screen. PMID- 27714533 TI - A method for predicting individual residue contributions to enzyme specificity and binding-site energies, and its application to MTH1. AB - A new method for predicting the energy contributions to substrate binding and to specificity has been developed. Conventional global optimization methods do not permit the subtle effects responsible for these properties to be modeled with sufficient precision to allow confidence to be placed in the results, but by making simple alterations to the model, the precisions of the various energies involved can be improved from about +/-2 kcal mol-1 to +/-0.1 kcal mol-1. This technique was applied to the oxidized nucleotide pyrophosphohydrolase enzyme MTH1. MTH1 is unusual in that the binding and reaction sites are well separated an advantage from a computational chemistry perspective, as it allows the energetics involved in docking to be modeled without the need to consider any issues relating to reaction mechanisms. In this study, two types of energy terms were investigated: the noncovalent interactions between the binding site and the substrate, and those responsible for discriminating between the oxidized nucleotide 8-oxo-dGTP and the normal dGTP. Both of these were investigated using the semiempirical method PM7 in the program MOPAC. The contributions of the individual residues to both the binding energy and the specificity of MTH1 were calculated by simulating the effect of mutations. Where comparisons were possible, all calculated results were in agreement with experimental observations. This technique provides fresh insight into the binding mechanism that enzymes use for discriminating between possible substrates. PMID- 27714534 TI - Calculations of BODIPY dyes in the ground and excited states using the M06-2X and PBE0 functionals. AB - A number of fluorescent dyes based on BODIPY (4,4'-difluoro-4-bora-3a,4a-diaza-s indacene) have been studied theoretically. This paper presents the results of calculations of these BODIPY dyes in their ground and excited states, performed using DFT and TD-DFT methods, respectively. The influences of N,N dimethylaminobenzyl, ortho-fluorophenol, and methyl substituents as well as the solvent polarity on the positions of the absorption and emission bands of the dyes were analyzed. The computational data obtained in this work were compared to the corresponding experimental data. The trends in the experimental data were found to agree with those shown by the computational data. Differences between the potential curves obtained when using linear-response (LR) and state-specific (SS) approaches for the ground and excited states are also reported. Graphical Abstract The article shows that the trends of the experimental dependencies lambdaabs = f(Deltaf) and lambdaem = f(Deltaf) well described by PBE0 (LR approach) and M06-2X (SS approach) calculations, respectively. The influence of substituents on the spectral characteristics of the BODIPY chromophore are analysed. PMID- 27714535 TI - Ultrastructural and physiological changes induced by different stress conditions on the human parasite Trypanosoma cruzi. AB - Trypanosoma cruzi is the etiological agent of Chagas disease. The life cycle of this protozoan parasite is digenetic because it alternates its different developmental forms through two hosts, a vector insect and a vertebrate host. As a result, the parasites are exposed to sudden and drastic environmental changes causing cellular stress. The stress response to some types of stress has been studied in T. cruzi, mainly at the molecular level; however, data about ultrastructure and physiological state of the cells in stress conditions are scarce or null. In this work, we analyzed the morphological, ultrastructural, and physiological changes produced on T. cruzi epimastigotes when they were exposed to acid, nutritional, heat, and oxidative stress. Clear morphological changes were observed, but the physiological conditions varied depending on the type of stress. The maintenance of the physiological state was severely affected by heat shock, acidic, nutritional, and oxidative stress. According to the surprising observed growth recovery after damage by stress alterations, different adaptations from the parasite to these harsh conditions were suggested. Particular cellular death pathways are discussed. PMID- 27714536 TI - Clinical outcomes of stage IV colorectal cancer after R0 resection: a multi institutional retrospective analysis. AB - BACKGROUND: We analyzed the treatment outcomes after curative surgery for stage IV colorectal cancer to develop outcome-based follow-up protocols and treatment strategies. METHODS: This study was a multi-institutional retrospective analysis of treatment outcomes in patients who underwent R0 surgery for stage IV colorectal cancer. RESULTS: A total of 1133 patients, of whom 837 had recurrence, were included in this study. Recurrence occurred within 12 and 24 months after R0 surgery in 452 (54.0 %) and 652 (77.9 %) patients, respectively. Surgical resection was performed less frequently for recurrence within 12 months of R0 surgery than for recurrence after more than 12 months (p = 0.003). Prognosis was significantly better in patients who had recurrence more than 24 months after R0 surgery than in those who had recurrence within 24 months; this was not only for all patients but also specifically for patients with resection for recurrent disease. Recurrence was less frequent in patients who received preoperative chemotherapy than in patients who did not receive preoperative chemotherapy (p = 0.04). Of significance, fewer patients who received preoperative chemotherapy (57.5 %) had recurrence within 24 months compared with patients who did not receive preoperative chemotherapy (79.8 %) (p = 0.00001). CONCLUSIONS: Intensive follow-up for at least 24 months was considered appropriate for monitoring disease recurrence after R0 surgery for stage IV colorectal cancer. In addition, preoperative chemotherapy contributed to improved outcomes.

PMID- 27714538 TI - Comparison of Salvage Total Pharyngolaryngectomy and Cervical Esophagectomy Between Hypopharyngeal Cancer and Cervical Esophageal Cancer. AB - BACKGROUND: Total pharyngolaryngectomy and cervical esophagectomy (TPLCE) after chemoradiotherapy remains a challenge because of the high rate of complications and few available data on outcomes and safety. The purpose of this study was to evaluate the clinical significance of salvage TPLCE and to compare treatment outcomes between hypopharyngeal cancer and cervical esophageal cancer. METHODS: Data from 37 consecutive patients who were diagnosed with potentially resectable hypopharyngeal and cervical esophageal cancer after chemoradiotherapy were retrospectively analyzed. The survival and surgical outcomes were investigated between the hypopharyngeal cancer and cervical esophageal cancer groups. RESULTS: Twenty-six patients were included in hypopharyngeal cancer group and 11 patients were included in cervical esophageal cancer group. The baseline characteristics were balanced between the two groups. Compared to the hypopharyngeal cancer group, the cervical esophageal cancer group had significantly more frequent tracheal-related complications (p < 0.05) and stronger association of distal margin of the cervical esophagus and radiation field with tracheal ischemia after salvage surgery. CONCLUSIONS: Salvage TPLCE can offer the exclusive chance of prolonged survival. Association of tracheal ischemia with salvage TPLCE was seen more frequently for cervical esophageal cancer. Therefore, the indication for salvage TPLCE must be carefully considered to maintain the balance between curability and safety. PMID- 27714539 TI - A Choice of Wine. PMID- 27714540 TI - Ultrasound-Guided Core-Needle Versus Vacuum-Assisted Breast Biopsy: A Cost Analysis Based on the American Society of Breast Surgeons' Mastery of Breast Surgery Registry. AB - PURPOSE: To evaluate the cost-efficacy of vacuum-assisted ultrasound-guided breast biopsy instruments compared to ultrasound-guided 14-gauge spring-loaded core-needle biopsy. METHODS: The American Society of Breast Surgeons' Mastery of Breast Surgery Registry was reviewed. Biopsy findings, any rebiopsy, and the instrument used were abstracted for 31,451 ultrasound-guided biopsy procedures performed between 2001 and July 2014. Rates of cancer diagnosis and rebiopsy were calculated for each instrument. A linear mathematical model was developed to calculate total cost per cancer diagnosis, including procedural costs and the costs of any additional surgical rebiopsy procedures. Mean cost per cancer diagnosis with confidence limits was then determined for 14-gauge spring-loaded core-needle biopsy and 14 different vacuum-assisted instruments. For 14-gauge spring-loaded core-needle biopsy, mean cost per cancer diagnosis was $4346 (4327 $4366). For the vacuum-assisted instruments, mean cost per cancer diagnosis ranged from a low of $3742 ($3732-$3752) to a high of $4779 ($4750-$4809). RESULTS: Vacuum-assisted instruments overall were more cost-effective than core with a mean cost per cancer diagnosis of $4052 ($4038-$4067) (p < 0.05). Tethered vacuum-assisted instruments performed best with a mean cost per cancer diagnosis of $3978 ($3964-$3991) (p < 0.05). Nontethered devices had a mean cost per cancer diagnosis of $4369 ($4350-$4388), a result no better than core (p < 0.05). CONCLUSIONS: Ultrasound-guided vacuum-assisted breast biopsy had a lower mean cost per cancer diagnosis than 14-gauge spring-loaded core-needle biopsy. This advantage was only seen in tethered vacuum-assisted instruments. Within device families, larger instruments tended to outperform smaller instruments. PMID- 27714542 TI - Lower Bounds to the Reliabilities of Factor Score Estimators. AB - Under the general common factor model, the reliabilities of factor score estimators might be of more interest than the reliability of the total score (the unweighted sum of item scores). In this paper, lower bounds to the reliabilities of Thurstone's factor score estimators, Bartlett's factor score estimators, and McDonald's factor score estimators are derived and conditions are given under which these lower bounds are equal. The relative performance of the derived lower bounds is studied using classic example data sets. The results show that estimates of the lower bounds to the reliabilities of Thurstone's factor score estimators are greater than or equal to the estimates of the lower bounds to the reliabilities of Bartlett's and McDonald's factor score estimators. PMID- 27714541 TI - Cabozantinib for metastatic breast carcinoma: results of a phase II placebo controlled randomized discontinuation study. AB - PURPOSE: Cabozantinib (XL184), a multi-targeted oral tyrosine kinase inhibitor with activity against MET, VEGFR2, AXL, and other tyrosine kinases, was assessed in a cohort of metastatic breast cancer (MBC) patients in a phase II randomized discontinuation trial (RDT). METHODS: Patients received 100 mg cabozantinib daily during a 12-week lead-in stage. Those with stable disease per modified Response Evaluation Criteria in Solid Tumors version 1.0 at 12 weeks were randomized to either continue cabozantinib or receive placebo. Primary endpoints were objective response rate (ORR) during the 12-week lead-in stage and progression-free survival (PFS) after randomization. Patients were also followed for overall survival (OS). RESULTS: Forty-five patients with MBC and a median of three prior lines of chemotherapy for metastatic disease were enrolled. The ORR during the lead-in stage was 13.6 % (95 % confidence interval [CI] 6-25.7 %), and the disease control rate at week 12 was 46.7 % (95 % CI 31.7-61.6 %). Per the initial RDT study design, patients with stable disease at week 12 were randomized to cabozantinib or placebo. Following a Study Oversight Committee recommendation, randomization was suspended. Patients in the lead-in stage continued on open label cabozantinib. Patients in the randomization stage were subsequently unblinded. The overall median PFS for all MBC patients was 4.3 months. Median OS was 11.4 months (95 % CI 10.5-16.5 months). The most common grade 3/4 adverse events in the lead-in stage were palmar-plantar erythrodysesthesia (13 %) and fatigue (11 %). One death from respiratory failure was reported as drug-related during the lead-in stage. CONCLUSIONS: In heavily pretreated MBC patients, cabozantinib monotherapy demonstrated clinical activity including objective response and disease control. PMID- 27714543 TI - Functional Generalized Structured Component Analysis. AB - An extension of Generalized Structured Component Analysis (GSCA), called Functional GSCA, is proposed to analyze functional data that are considered to arise from an underlying smooth curve varying over time or other continua. GSCA has been geared for the analysis of multivariate data. Accordingly, it cannot deal with functional data that often involve different measurement occasions across participants and a large number of measurement occasions that exceed the number of participants. Functional GSCA addresses these issues by integrating GSCA with spline basis function expansions that represent infinite-dimensional curves onto a finite-dimensional space. For parameter estimation, functional GSCA minimizes a penalized least squares criterion by using an alternating penalized least squares estimation algorithm. The usefulness of functional GSCA is illustrated with gait data. PMID- 27714544 TI - A Procedure for Assessing the Completeness of the Q-Matrices of Cognitively Diagnostic Tests. AB - The Q-matrix of a cognitively diagnostic test is said to be complete if it allows for the identification of all possible proficiency classes among examinees. Completeness of the Q-matrix is therefore a key requirement for any cognitively diagnostic test. However, completeness of the Q-matrix is often difficult to establish, especially, for tests with a large number of items involving multiple attributes. As an additional complication, completeness is not an intrinsic property of the Q-matrix, but can only be assessed in reference to a specific cognitive diagnosis model (CDM) supposed to underly the data-that is, the Q matrix of a given test can be complete for one model but incomplete for another. In this article, a method is presented for assessing whether a given Q-matrix is complete for a given CDM. The proposed procedure relies on the theoretical framework of general CDMs and is therefore legitimate for CDMs that can be reparameterized as a general CDM.

PMID- 27714546 TI - Characterization and in vitro sensitivity of cholinesterases of gilthead seabream (Sparus aurata) to organophosphate pesticides. AB - The characterization of cholinesterase activity in brain and muscle of gilthead seabream was carried out using four specific substrates and three selective inhibitors. In addition, K m and V max were calculated from the Michaelis-Menten equation for ASCh and BSCh substrates. Finally, the in vitro sensitivity of brain and muscle cholinesterases to three organophosphates (OPs) was also investigated by estimating inhibition kinetics. The results indicate that AChE is the enzyme present in the brain, whereas in muscle, a typical AChE form is present along with an atypical form of BChE. Very low ChE activity was found in plasma with all substrates used. The inhibitory potency of the studied OPs on brain and muscle AChEs based on bimolecular inhibition constants (k i ) was: omethoate < dichlorvos < azinphosmethyl-oxon. Furthermore, muscle BChE was found to be several orders of magnitude (from 2 to 4) more sensitive than brain and muscle AChE inhibition by dichlorvos and omethoate.

AB - (2E)-3-[4-(dimethylamino)phenyl]-1-(2-hydroxyphenyl)prop-2-en-1-one (DPHP) was synthesized by the reaction 4(dimethylamino) benzaldehyde with 1-(2 hydroxyphenyl) ethanone under microwave irradiation. Structure of DPHP was conformed by 1H and 13C NMR, FT-IR, EI-MS spectral studies and elemental analysis. The electronic absorption and fluorescence spectra of DPHP have been studied in solvents of different polarities, and the data were used to study the solvatochromic properties such as extinction coefficient, stokes shift, oscillator strength, transition dipole moment, fluorescence quantum yield and photochemical quantum yield. The absorption maximum and fluorescence emission maximum was observed red shift when increase solvent polarity n-Hexane to DMF. DPHP undergoes solubilization in different micelles and may be used as a probe and quencher to determine the critical micelle concentration (CMC) of CTAB and SDS. PMID- 27714550 TI - Mapping face encoding using functional MRI in multiple sclerosis across disease phenotypes. AB - Using fMRI during a face encoding (FE) task, we investigated the behavioral and fMRI correlates of FE in patients with relapse-onset multiple sclerosis (MS) at different stages of the disease and their relation with attentive-executive performance and structural MRI measures of disease-related damage. A fMRI FE task was administered to 75 MS patients (11 clinically isolated syndromes - CIS, 40 relapsing-remitting - RRMS - and 24 secondary progressive - SPMS) and 22 healthy controls (HC). fMRI activity during the face encoding condition was correlated with behavioral, clinical, neuropsychological and structural MRI variables. All study subjects activated brain regions belonging to face perception and encoding network, and deactivated areas of the default-mode network. Compared to HC, MS patients had the concomitant presence of areas of increased and decreased activations as well as increased and decreased deactivations. Compared to HC or RRMS, CIS patients experienced an increased recruitment of posterior-visual areas. Thalami, para-hippocampal gyri and right anterior cingulum were more activated in RRMS vs CIS or SPMS patients, while an increased recruitment of frontal areas was observed in SPMS vs RRMS. Areas of abnormal activations were significantly correlated with clinical, cognitive-behavioral and structural MRI measures. Abnormalities of FE network occur in MS and vary across disease clinical phenotypes. Early in the disease, an increased recruitment of areas typically devoted to face perception and encoding occurs. In SPMS patients, abnormal functional recruitment of frontal lobe areas might contribute to the severity of clinical manifestations. PMID- 27714549 TI - Systemic klotho is associated with KLOTHO variation and predicts intrinsic cortical connectivity in healthy human aging. AB - Cognitive decline is a major biomedical challenge as the global population ages. Elevated levels of the longevity factor klotho suppress aging, enhance cognition, and promote synaptic plasticity and neural resilience against aging and Alzheimer's disease (AD)-related pathogenic proteins. Here, we examined the relationship between human genetic variants of KLOTHO and systemic klotho levels and assessed neuroanatomic correlates of serum klotho in a cohort of healthy older adults. Serum klotho levels were increased with KL-VS heterozygosity, as anticipated. We report, for the first time, that serum klotho levels were paradoxically decreased with KL-VS homozygosity. Further, we found that higher serum klotho levels were associated with measures of greater intrinsic connectivity in key functional networks of the brain vulnerable to aging and AD such as the fronto-parietal and default mode networks. Our findings suggest that elevated klotho promotes a resilient brain, possibly through increased network connectivity of critical brain regions. PMID- 27714551 TI - Cerebral perfusion alterations in type 2 diabetes and its relation to insulin resistance and cognitive dysfunction. AB - To explore the effect of T2DM on cerebral perfusion, and the relationship between cerebral perfusion changes and cognitive impairment as well as diabetic variables, by using a whole-brain arterial spin-labeling (ASL) MRI technique. This prospective study was approved by the local institutional review board and was performed between November 2012 and October 2013. All subjects provided informed consent. Forty T2DM patients and 41 age-, sex- and education-matched healthy controls were included. Cerebral blood flow (CBF) map was obtained by pulsed ASL perfusion imaging at 3 T MRI. Voxel-wise comparisons on CBF maps with and without partial volume effects (PVEs) correction were performed between groups. Associations between CBF and cognitive functioning, and between CBF and diabetic variables were investigated by using voxel-wise, whole-brain correlation analyses. In T2DM patients, PVEs uncorrected CBF was decreased in the posterior cingulate cortex (PCC), precuneus and bilateral occipital lobe, and increased in the anterior cingulate cortex (corrected P < .05). These changes were largely unchanged after PVEs correction. Correlation analyses revealed that in patients, hypoperfusion in PCC and precuneus regions were related to higher insulin resistance level and deficits in clock-drawing performance, while the occipital hypoperfusion was associated with worse visual-memory performance, regardless of PVEs correction. The cerebral hypoperfusion pattern in T2DM resembles the pattern observed in the early stage of dementia, and increased insulin resistance might be an important risk factor as well as treatment target for such CBF dysregulation. PMID- 27714553 TI - Beta-adrenergic antagonism modulates functional connectivity in the default mode network of individuals with and without autism spectrum disorder. AB - The beta-adrenergic antagonist propranolol benefits some social and communication domains affected in autism spectrum disorder (ASD), and these benefits appear to be associated with increased functional connectivity (FC) in the brain during task performance. FC is implicated in ASD, with the majority of studies suggesting long distance hypo-connectivity combined with regionally specific local hyper-connectivity. The objective in the current investigation was to examine the effect of propranolol on FC at rest and determine whether ASD specific effects exist. Participants with and without ASD attended three sessions in which propranolol, nadolol (a beta-adrenergic antagonist that does not cross the blood-brain barrier), or placebo were administered. Resting-state fMRI data were acquired, and graph theory techniques were utilized to assess additional aspects of FC. Compared to placebo, propranolol administration was associated with decreased FC in the dorsal medial prefrontal cortex subnetwork of the default mode network and increased FC in the medial temporal lobe subnetwork, regardless of diagnosis. These effects were not seen with nadolol suggesting that the alterations in FC following propranolol administration were not exclusively due to peripheral cardiovascular effects. Thus, beta-adrenergic antagonism can up or down- regulate FC, depending on the network, and alter coordinated functional activation in the brain. These changes in information processing, as demonstrated by FC, may mediate some of the clinical and behavioral effects of beta-adrenergic antagonism previously reported in patients with ASD. PMID- 27714554 TI - Intrinsic functional connectivity alterations in cognitively intact elderly APOE epsilon4 carriers measured by eigenvector centrality mapping are related to cognition and CSF biomarkers: a preliminary study. AB - Apolipoprotein E (APOE) epsilon4 allele is the best established genetic risk factor for sporadic Alzheimer's disease (AD). However, there is a need to understand the effects of this genotype on the brain by simultaneously assessing intrinsic brain network and cerebral spinal fluid (CSF) biomarkers changes in healthy older epsilon4 carriers. Thirteen cognitively intact, elderly APOE epsilon4 carriers and 22 epsilon3 homozygotes were included in the present study. Eigenvector centrality mapping (ECM) was used to identify brain network hub organization based on resting-state functional MRI (rsfMRI). We evaluated comprehensive cognitive ability and tested levels of Abeta1-42, total-tau (t-tau) and phosphorylated-tau (p-tau181) in CSF. Comparisons of ECM between two groups were conducted, followed by correlations analyses between EC values with significant group differences and cognitive ability/CSF biomarkers. APOE epsilon4 carriers showed significantly decreased EC values in left medial temporal lobe (MTL), left lingual gyrus (LG) and increased EC values in left middle frontal gyrus (MFG) as compared to non-carriers. Correlation analysis demonstrated that left LG EC value correlated with Rey Auditory Verbal Learning Test total learning (RAVLT, r = 0.57, p < 0.05) and t-tau level (r = -0.57, p < 0.05), while left MFG EC values correlated with log-transformed Trail-Making Test B (TMT-B, r = -0.67, p < 0.05) in APOE epsilon4 carriers. This study suggests the APOE epsilon4 allele contributes to disruption of brain connectedness in certain functional nodes, which may result from neuronal death caused by toxicity of neurofibrillary tangles. PMID- 27714552 TI - Mapping temporo-parietal and temporo-occipital cortico-cortical connections of the human middle longitudinal fascicle in subject-specific, probabilistic, and stereotaxic Talairach spaces. AB - Originally, the middle longitudinal fascicle (MdLF) was defined as a long association fiber tract connecting the superior temporal gyrus and temporal pole with the angular gyrus. More recently its description has been expanded to include all long postrolandic cortico-cortical association connections of the superior temporal gyrus and dorsal temporal pole with the parietal and occipital lobes. Despite its location and size, which makes MdLF one of the most prominent cerebral association fiber tracts, its discovery in humans is recent. Given the absence of a gold standard in humans for this fiber tract, its precise and complete connectivity remains to be determined with certainty. In this study using high angular resolution diffusion MRI (HARDI), we delineated for the first time, six major fiber connections of the human MdLF, four of which are temporo parietal and two temporo-occipital, by examining morphology, topography, cortical connections, biophysical measures, volume and length in seventy brains. Considering the cortical affiliations of the different connections of MdLF we suggested that this fiber tract may be related to language, attention and integrative higher level visual and auditory processing associated functions. Furthermore, given the extensive connectivity provided to superior temporal gyrus and temporal pole with the parietal and occipital lobes, MdLF may be involved in several neurological and psychiatric conditions such as primary progressive aphasia and other aphasic syndromes, some forms of behavioral variant of frontotemporal dementia, atypical forms of Alzheimer's disease, corticobasal degeneration, schizophrenia as well as attention-deficit/hyperactivity Disorder and neglect disorders. PMID- 27714555 TI - Biocatalytic characterization of an endo-beta-1,4-mannanase produced by Paenibacillus sp. strain HY-8. AB - OBJECTIVES: To evaluate the biocatalytic characteristics of a new endo-beta-1,4-D mannan-degrading enzyme (ManP) from Paenibacillus sp. strain HY-8, a gut bacterium of the longicorn beetle Moechotypa diphysis. RESULTS: Purified ManP (32 kDa) with an N-terminal amino acid sequence of APSFAVGADFSYVPG displayed the greatest degree of biocatalytic activity toward locust bean gum (LBG) at 55 degrees C and pH 7.0. The enzyme degraded LBG, guar gum, ivory nut mannan, and mannooligosaccharides (M2-M5), but did not exhibit any hydrolytic activity against structurally unrelated substrates. The biocatalytic activity of ManP against LBG and guar gum was 695 and 450 U mg-1, respectively. Especially, enzymatic hydrolysis of mannobiose yielded a mixture of mannose (16.6 %) and mannobiose (83.4 %), although the degree of mannobiose degradation by ManP with was relatively limited. CONCLUSION: The present results suggest that ManP is an endo-beta-1,4-mannanase and is distinct from various other characterized endo beta-1,4-mannanases.

AB - OBJECTIVES: To characterize a biosynthetic gene that is selectively involved in the biosynthesis of yellow or orange components in the azaphilone polyketide pathway of Monascus. RESULTS: A reductive modification is predicted to control the relative levels of reduced (yellow) and oxidized (orange and red) components in the pathway of azaphilone pigment biosynthesis in Monascus. Targeted inactivation of a reductase gene mppE enhanced orange and red pigment production whereas overexpression of the gene promoted yellow pigment production. The effect of mppE overexpression was dependent on culture methods, and augmented yellow pigmentation was evident in a submerged culture employing a chemically defined medium. CONCLUSIONS: MppE controls the biosynthesis of the yellow pigments, ankaflavin and monascin, as a reductive enzyme in the azaphilone polyketide pathway.

AB - OBJECTIVES: To establish an efficient method of chemoenzymatic modification for making N-linked oligosaccharide chains of glycoproteins structurally homogeneous, which crucially affects their bioactivities. RESULTS: Deglycosylated-RNase B (GlcNAc-RNase B; acceptor), sialylglyco (SG)-oxazoline (donor) and an N180H mutant of Coprinopsis cinerea endo-beta-N-acetylglucosaminidase (Endo-CCN180H) were employed. pH 7.5 was ideal for both SG-oxazoline's stability and Endo-CC's transglycosylation reaction. The most efficient reaction conditions for producing glycosylated-RNase B, virtually modified completely with sialo-biantennary-type complex oligosaccharide, were: 80 MUg GlcNAc-RNase B, 200 MUg SG-oxazoline and 3 MUg Endo-CCN180H in 20 MUl 20 mM Tris/HCl pH 7.5 at 30 degrees C for 30-60 min. CONCLUSIONS: This transglycosylation method using SG-oxazoline and Endo-CCN180H is beneficial for producing pharmaceutical glycoproteins modified with homogenous biantennary-complex-type oligosaccharides. PMID- 27714558 TI - A novel trichosanthin fusion protein with increased cytotoxicity to tumor cells. AB - OBJECTIVE: To evaluate the anti-tumor effects of trichosanthin after fusion with a cell penetrating peptide, heparin-binding peptide (HBP), derived from human heparin-binding EGF-like growth factor (HB-EGF). RESULTS: The fusion protein of trichosanthin-HBP was expressed in Escherichia coli BL21 and purified by Ni-NTA affinity chromatography. The HBP domain had no influence on the topological inactivation activity and N-glycosidase activity of trichosanthin. Trichosanthin HBP significantly inhibited the growth of tested cancer cells which are impervious to trichosanthin. Tumor cell apoptosis and both the mitochondrial- and death receptor-mediated apoptotic signaling pathways induced by trichosanthin-HBP were more significant than those induced by trichosanthin in HeLa cells. CONCLUSION: HBP is an efficient intracellular delivery vehicle for trichosanthin and makes trichosanthin-HBP become a promising agent for cancer therapy. PMID- 27714559 TI - CaCO3 supplementation alleviates the inhibition of formic acid on acetone/butanol/ethanol fermentation by Clostridium acetobutylicum. AB - OBJECTIVE: To investigate the inhibiting effect of formic acid on acetone/butanol/ethanol (ABE) fermentation and explain the mechanism of the alleviation in the inhibiting effect under CaCO3 supplementation condition. RESULTS: From the medium containing 50 g sugars l-1 and 0.5 g formic acid l-1, only 0.75 g ABE l-1 was produced when pH was adjusted by KOH and fermentation ended prematurely before the transformation from acidogenesis to solventogenesis. In contrast, 11.4 g ABE l-1 was produced when pH was adjusted by 4 g CaCO3 l-1. The beneficial effect can be ascribed to the buffering capacity of CaCO3. Comparative analysis results showed that the undissociated formic acid concentration and acid production coupled with ATP and NADH was affected by the pH buffering capacity of CaCO3. Four millimole undissociated formic acid was the threshold at which the transformation to solventogenesis occurred. CONCLUSION: The inhibiting effect of formic acid on ABE fermentation can be alleviated by CaCO3 supplementation due to its buffering capacity. PMID- 27714560 TI - Barriers to Electronic Health Record Adoption: a Systematic Literature Review. AB - Federal efforts and local initiatives to increase adoption and use of electronic health records (EHRs) continue, particularly since the enactment of the Health Information Technology for Economic and Clinical Health (HITECH) Act. Roughly one in four hospitals not adopted even a basic EHR system. A review of the barriers may help in understanding the factors deterring certain healthcare organizations from implementation. We wanted to assemble an updated and comprehensive list of adoption barriers of EHR systems in the United States. Authors searched CINAHL, MEDLINE, and Google Scholar, and accepted only articles relevant to our primary objective. Reviewers independently assessed the works highlighted by our search and selected several for review. Through multiple consensus meetings, authors tapered articles to a final selection most germane to the topic (n = 27). Each article was thoroughly examined by multiple authors in order to achieve greater validity. Authors identified 39 barriers to EHR adoption within the literature selected for the review. These barriers appeared 125 times in the literature; the most frequently mentioned barriers were regarding cost, technical concerns, technical support, and resistance to change. Despite federal and local incentives, the initial cost of adopting an EHR is a common existing barrier. The other most commonly mentioned barriers include technical support, technical concerns, and maintenance/ongoing costs. Policy makers should consider incentives that continue to reduce implementation cost, possibly aimed more directly at organizations that are known to have lower adoption rates, such as small hospitals in rural areas. PMID- 27714561 TI - Estimation of Temporal Gait Events from a Single Accelerometer Through the Scale Space Filtering Idea. AB - The purpose of this paper is to develop an accelerometry system capable of performing gait event demarcation and calculation of temporal parameters using a single waist-mounted device. Particularly, a mobile phone positioned over the L2 vertebra is used to acquire trunk accelerations during walking. Signals from the acceleration magnitude and the vertical acceleration are smoothed through different filters. Cut-off points between filtered signals as a result of convolving with varying levels of Gaussian filters and other robust features against temporal variation and noise are used to identify peaks that correspond to gait events. Five pre-frail older adults and five young healthy adults were recruited in an experiment. Cadence, step/stride time, step/stride CV, step asymmetry and percentages of the stance/swing and single/double support phases, among the two groups of different mobility were quantified by the system. PMID- 27714562 TI - Patient-Controlled Attribute-Based Encryption for Secure Electronic Health Records System. AB - In recent years, many countries have been trying to integrate electronic health data managed by each hospital to offer more efficient healthcare services. Since health data contain sensitive information of patients, there have been much research that present privacy preserving mechanisms. However, existing studies either require a patient to perform various steps to secure the data or restrict the patient to exerting control over the data. In this paper, we propose patient controlled attribute-based encryption, which enables a patient (a data owner) to control access to the health data and reduces the operational burden for the patient, simultaneously. With our method, the patient has powerful control capability of his/her own health data in that he/she has the final say on the access with time limitation. In addition, our scheme provides emergency medical services which allow the emergency staffs to access the health data without the patient's permission only in the case of emergencies. We prove that our scheme is secure under cryptographic assumptions and analyze its efficiency from the patient's perspective. PMID- 27714563 TI - Performance Analysis of Fuzzy-PID Controller for Blood Glucose Regulation in Type 1 Diabetic Patients. AB - This paper presents Fuzzy-PID (FPID) control scheme for a blood glucose control of type 1 diabetic subjects. A new metaheuristic Cuckoo Search Algorithm (CSA) is utilized to optimize the gains of FPID controller. CSA provides fast convergence and is capable of handling global optimization of continuous nonlinear systems. The proposed controller is an amalgamation of fuzzy logic and optimization which may provide an efficient solution for complex problems like blood glucose control. The task is to maintain normal glucose levels in the shortest possible time with minimum insulin dose. The glucose control is achieved by tuning the PID (Proportional Integral Derivative) and FPID controller with the help of Genetic Algorithm and CSA for comparative analysis. The designed controllers are tested on Bergman minimal model to control the blood glucose level in the facets of parameter uncertainties, meal disturbances and sensor noise. The results reveal that the performance of CSA-FPID controller is superior as compared to other designed controllers. PMID- 27714564 TI - Heat shock protein-27 (HSP27) regulates STAT3 and eIF4G levels in first trimester human placenta. AB - During placental implantation, cytotrophoblast cells differentiate to extravillous trophoblast (EVT) cells that invade from the placenta into the maternal uterine blood vessels. The heat shock protein-27 (HSP27), the signal transducer and activator of transcription-3 (STAT3) and the eukaryotic translation initiation factor 4E (EIF4E) are involved in regulating EVT cell differentiation/migration. EIF4E and EIF4G compose the translation initiation complex, which is a major control point in protein translation. The molecular chaperone distinctiveness of HSP27 implies that it directly interferes with many target proteins. STAT3, EIF4E, and EIF4G were found to be HSP27 client proteins in tumor cells. We aimed to analyze if HSP27 regulate STAT3 and EIF4G levels in first trimester human placenta. We found that like STAT3, EIF4G is highly expressed in the EVT cells (immunohistochemistry). Silencing HSP27 in HTR-8/SVneo cells (siRNA, EVT cell line) and in placental explants reduced STAT3 level (47 and 33 %, respectively, p < 0.05). HSP27 silencing reduced the levels of STAT3 phosphorylation (33 % reduction, p < 0.05) and targets (IRF1, MUC1, MMP2/9 and EIF4E, 30-49 % reduction, p < 0.05) in the HTR-8/SVneo cells. Moreover, HSP27 silencing significantly reduced EIF4G level and elevated the level of its fragments in HTR-8/SVneo cells and in the placental explants (p < 0.05). In conclusion, Placental implantation and development are accompanied by trophoblast cell proliferation and differentiation, which necessitates intense protein translation and STAT3 activation. HSP27 was found to be regulator of translation initiation and STAT3 level. Therefore, it suggests that HSP27 is a key protein during placental development and trophoblast cell differentiation. PMID- 27714565 TI - Asthma and Hypogammaglobulinemia: an Asthma Phenotype with Low Type 2 Inflammation. AB - PURPOSE: Little is known about hypogammaglobulinemia (HGG) in asthma patients. No data are available on the characteristics of adult patients with asthma and HGG. METHODS: We conducted a retrospective monocentric study between January 2006 and December 2012. Asthma patients with a serum immunoglobulin (Ig) quantitative analysis were included and classified into two groups depending on their serum IgG concentration: presence or absence of HGG. Clinical, biological, functional, and radiologic characteristics were compared in univariate and multivariate analysis, using a logistic regression model. RESULTS: In univariate analysis, asthma patients with HGG (n = 25) were older (58 years old +/- 18 vs 49 +/- 18, p = 0.04) and more frequently active or former smokers as compared to patients with normoglobulinemia (n = 80) (56.0 vs 35.0 %, p = 0.01). Total IgE < 30 kUI/L was more frequently observed in patients with HGG (53.0 vs 18.3 %, p = 0.01). HGG asthma patients had lower fraction of exhaled nitric oxide (p = 0.02), blood eosinophilia (p = 0.0009), and presented with more severe composite score for bronchiectasis (p = 0.01). In multivariate analysis, asthma patients with HGG had increased risk of being smokers [OR = 6.11 (IC 95 % = 1.16-32.04)], having total IgE concentration < 30 kUI/L [OR = 12.87 (IC 95 % = 2.30-72.15)], and a more severe composite score of bronchiectasis [OR = 20.65 (IC 95 % = 2.13-199.74)]. CONCLUSION: Asthma patients with HGG are older and more often tobacco smoker than asthma patients without HGG. These patients have low type-2 inflammation markers. PMID- 27714566 TI - Acquisition models in intraoperative positron surface imaging. AB - PURPOSE: Intraoperative imaging aims at identifying residual tumor during surgery. Positron Surface Imaging (PSI) is one of the solutions to help surgeons in a better detection of resection margins of brain tumor, leading to an improved patient outcome. This system relies on a tracked freehand beta probe, using [Formula: see text]F-based radiotracer. Some acquisition models have been proposed in the literature in order to enhance image quality, but no comparative validation study has been performed for PSI. METHODS: In this study, we investigated the performance of different acquisition models by considering validation criteria and normalized metrics. We proposed a reference-based validation framework to perform the comparative study between acquisition models and a basic method. We estimated the performance of several acquisition models in light of four validation criteria: efficiency, computational speed, spatial accuracy and tumor contrast. RESULTS: Selected acquisition models outperformed the basic method, albeit with the real-time aspect compromised. One acquisition model yielded the best performance among all according to the validation criteria: efficiency (1-Spe: 0.1, Se: 0.94), spatial accuracy (max Dice: 0.77) and tumor contrast (max T/B: 5.2). We also found out that above a minimum threshold value of the sampling rate, the reconstruction quality does not vary significantly. CONCLUSION: Our method allowed the comparison of different acquisition models and highlighted one of them according to our validation criteria. This novel approach can be extended to 3D datasets, for validation of future acquisition models dedicated to intraoperative guidance of brain surgery. PMID- 27714567 TI - Central X-ray beam correction of radiographic acetabular cup measurement after THA: an experimental study. AB - PURPOSE: Accurate assessment of cup orientation on postoperative radiographs is essential for evaluating outcome after THA. However, accuracy is impeded by the deviation of the central X-ray beam in relation to the cup and the impossibility of measuring retroversion on standard pelvic radiographs. METHOD: In an experimental trial, we built an artificial cup holder enabling the setting of different angles of anatomical anteversion and inclination. Twelve different cup orientations were investigated by three examiners. After comparing the two methods for radiographic measurement of the cup position developed by Lewinnek and Widmer, we showed how to differentiate between anteversion and retroversion in each cup position by using a second plane. To show the effect of the central beam offset on the cup, we X-rayed a defined cup position using a multidirectional central beam offset. According to Murray's definition of anteversion and inclination, we created a novel corrective procedure to balance measurement errors caused by deviation of the central beam. RESULTS: Measurement of the 12 different cup positions with the Lewinnek's method yielded a mean deviation of [Formula: see text] (95 % CI 1.3-2.3) from the original cup anteversion. The respective deviation with the Widmer/Liaw's method was [Formula: see text] (95 % CI 2.4-4.0). In each case, retroversion could be differentiated from anteversion with a second radiograph. Because of the multidirectional central beam offset ([Formula: see text] cm) from the acetabular cup in the cup holder ([Formula: see text] anteversion and [Formula: see text] inclination), the mean absolute difference for anteversion was [Formula: see text] (range [Formula: see text] to [Formula: see text] and [Formula: see text] (range [Formula: see text] to [Formula: see text] for inclination. The application of our novel mathematical correction of the central beam offset reduced deviation to a mean difference of [Formula: see text] for anteversion and [Formula: see text] for inclination. CONCLUSION: This novel calculation for central beam offset correction enables highly accurate measurement of the cup position.

AB - Integration of multiple sensory cues can improve performance in detection and estimation tasks. There is an open theoretical question of the conditions under which linear or nonlinear cue combination is Bayes-optimal. We demonstrate that a neural population decoded by a population vector requires nonlinear cue combination to approximate Bayesian inference. Specifically, if cues are conditionally independent, multiplicative cue combination is optimal for the population vector. The model was tested on neural and behavioral responses in the barn owl's sound localization system where space-specific neurons owe their selectivity to multiplicative tuning to sound localization cues interaural phase (IPD) and level (ILD) differences. We found that IPD and ILD cues are approximately conditionally independent. As a result, the multiplicative combination selectivity to IPD and ILD of midbrain space-specific neurons permits a population vector to perform Bayesian cue combination. We further show that this model describes the owl's localization behavior in azimuth and elevation. This work provides theoretical justification and experimental evidence supporting the optimality of nonlinear cue combination. PMID- 27714571 TI - Correlation of TLR4 and KLF7 in Inflammation Induced by Obesity. AB - Objective Recent studies have revealed a link between toll-like receptors (TLRs), Kruppel-like factors (KLFs), and the adipose tissue inflammation associated with obesity. TLR4 is associated with chronic inflammation in obesity. KLF7 is known to play an important role in the differentiation of adipocytes, but its role in visceral adipose tissue inflammation has not yet been investigated. Thus, the objective of this study was to determine the correlation of TLR4 and KLF7 in inflammation induced by obesity. Methods A total of 32 Wistar male rat subjects were fed in the center for experimental animals of Shihezi University. The rats were divided into normal control (NC) and high-fat diet (HFD) group. Surgical instruments were used to collect rats' visceral adipose tissue samples in the 10th week after HFD feeding. Ninety-five Uygur subjects between 20 and 90 years old were enrolled in the present study. The subjects were divided into two groups: the normal control group (NC, 18.0 kg/m2 <= BMI <= 23.9 kg/m2, n = 50) and the obesity group (OB, BMI >= 28 kg/m2, n = 45), and visceral adipose tissue was collected from the subjects. Anthropometric and clinical parameters were measured using standard procedures; biochemical indices were detected using the glucose oxidase-peroxidase method and a standardized automatic biochemistry analyzer; the plasma levels of inflammatory factors and adipocytokines were measured by enzyme-linked immunosorbent assay (ELISA); the mRNA and protein expression levels of key genes involved in the inflammatory signaling pathway were measured by real-time PCR and Western blot. Results In rats, compared with the NC group, the weight, Lee's index, waist circumference, visceral fat mass, and the plasma level of Glu, TG, FFA, and TNF-alpha were higher in the HFD group, while the plasma levels of LPT and APN were significantly lower in the HFD group in the 10th week. Furthermore, compared with the NC group, visceral adipose tissue's mRNA expression levels of TLR4, KLF7, and SRC were higher in the HFD group, and KLF7 was significantly positively correlated with LDL, TLR4, SRC, and IL-6 (P < 0.05). Meanwhile, in the Uygur population, the plasma levels of TG, LDL, and TNF-alpha in the OB group were significantly higher than those in the NC group (P < 0.05). Moreover, compared with the NC group, visceral adipose tissue's mRNA expression levels of TLR4, KLF7, and SRC were significantly higher in the OB group (P < 0.05), and KLF7 was significantly positively correlated with TC, TLR4, MYD88, SRC, and IL-6 (P < 0.05); the protein expression levels of TLR4 and KLF7 were significantly higher than those in the NC group (P < 0.05). Conclusion Higher expression of TLR4 and KLF7 may play a vital role in the process of inflammation induced by obesity in visceral adipose tissue. PMID- 27714572 TI - Wound stability and surgically induced corneal astigmatism after transconjunctival single-plane sclerocorneal incision cataract surgery. AB - PURPOSE: To compare intraocular pressure (IOP) immediately after cataract surgery, and surgically induced corneal astigmatism (SIA) and corneal shape changes between eyes with transconjunctival single-plane sclerocorneal incisions (TSSIs) and eyes with clear corneal incisions (CCIs). METHODS: Bilateral eyes of 64 patients undergoing phacoemulsification were randomized to undergo 2.4-mm temporal TSSI or CCI. IOP was measured preoperatively, and in the immediate postoperative periods. SIA was determined using vector analysis, and corneal shape changes and irregular astigmatism were evaluated using a videokeratography preoperatively, and in the early postoperative periods. RESULTS: Wound hydration was performed in 23 eyes (35.9 %) of the TSSI group and in 60 (93.8 %) of the CCI group (P < 0.0001). Mean IOP was significantly higher in the TSSI group than in the CCI group at 30, 60, and 120 min postoperatively (P <= 0.0179). SIA tended to be smaller in the TSSI group than the CCI group, but the difference was not significant. The higher order irregular astigmatism was smaller in the TSSI group than in the CCI group at 2 days (P = 0.0312). The videokeratography revealed a wound-related flattening postoperatively in both groups; this change disappeared within 4 weeks in the TSSI group, whereas it persisted until 12 weeks in the CCI group. CONCLUSION: IOP was significantly higher immediately after TSSI than after CCI and required less wound hydration, suggesting better stability with TSSI. Higher order irregular astigmatism and wound-related corneal flattening were smaller after TSSI than after CCI in the early periods, suggesting that fewer corneal shape changes with TSSI. PMID- 27714570 TI - Mathematical Models for Immunology: Current State of the Art and Future Research Directions. AB - The advances in genetics and biochemistry that have taken place over the last 10 years led to significant advances in experimental and clinical immunology. In turn, this has led to the development of new mathematical models to investigate qualitatively and quantitatively various open questions in immunology. In this study we present a review of some research areas in mathematical immunology that evolved over the last 10 years. To this end, we take a step-by-step approach in discussing a range of models derived to study the dynamics of both the innate and immune responses at the molecular, cellular and tissue scales. To emphasise the use of mathematics in modelling in this area, we also review some of the mathematical tools used to investigate these models. Finally, we discuss some future trends in both experimental immunology and mathematical immunology for the upcoming years. PMID- 27714573 TI - Subjective Cognitive Complaints and Objective Cognitive Function in Aging: A Systematic Review and Meta-Analysis of Recent Cross-Sectional Findings. AB - Research investigating how subjective cognitive complaints (SCCs) might reliably indicate impairments in objective cognitive functioning has produced highly varied findings, and despite attempts to synthesise this literature (e.g., Jonker et al. International Journal of Geriatric Psychiatry, 15, 983-991, 2000; Reid and MacLullich Dementia and Geriatric Cognitive Disorders, 22(5-6), 471-485, 2006; Crumley et al. Psychology and Aging, 29(2), 250-263, 2014), recent work continues to offer little resolution. This review provides both quantitative and qualitative synthesis of research conducted since the last comprehensive review in 2006, with the aim of identifying reasons for these discrepancies that might provide fruitful avenues for future exploration. Meta-analysis found a small but significant association between SCCs and objective cognitive function, although it was limited by large heterogeneity between studies and evidence of potential publication bias. Often, assessments of SCCs and objective cognitive function were brief or not formally validated. However, studies that employed more comprehensive SCC measures tended to find that SCCs were associated independently with both objective cognitive function and depressive symptoms. Further explicit investigation of how assessment measures relate to reports of SCCs, and the validity of the proposed 'compensation theory' of SCC aetiology, is recommended. PMID- 27714574 TI - D-Pinitol in Fabaceae: an Oviposition Stimulant for the Common Grass Yellow Butterfly, Eurema mandarina. AB - The common grass yellow butterfly, Eurema mandarina (formerly Eurema hecabe mandarina) (Lepidoptera, Pieridae), recently has been separated taxonomically from a subtropical population of Eurema hecabe in Japan. This species is widely distributed in the temperate region of Japan, and feeds mainly on various ligneous plants within the Fabaceae. We attempted to identify an oviposition stimulant for E. mandarina from its primary hosts, Albizia julibrissin and Lespedeza cuneata. In both hosts, crude extract and an aqueous fraction elicited oviposition responses from gravid females. A polar subfraction of the aqueous fraction also stimulated high oviposition-stimulatory activity, comparable to the original aqueous fraction, suggesting that E. mandarina females use water-soluble compounds for host recognition. Subsequent activity-directed fractionation by ion exchange chromatography indicated that one of the key substances was contained in the neutral/amphoteric fraction. Chemical analyses revealed that the active fractions of both hosts contained D-(+)-pinitol as the major component. We examined female responses to authentic D-pinitol and found that it induced oviposition responses at concentrations greater than 0.1 %. Since this cyclitol is omnipresent in Fabaceae, we conclude that D-pinitol plays a role in mediating oviposition of E. mandarina on fabaceous plants. PMID- 27714575 TI - AGEs/sRAGE, a novel risk factor in the pathogenesis of end-stage renal disease. AB - Interaction of advanced glycation end products (AGEs) with its cell-bound receptor (RAGE) results in cell dysfunction through activation of nuclear factor kappa-B, increase in expression and release of inflammatory cytokines, and generation of oxygen radicals. Circulating soluble receptors, soluble receptor (sRAGE), endogenous secretory receptor (esRAGE) and cleaved receptor (cRGAE) act as decoy for RAGE ligands and thus have cytoprotective effects. Low levels of sRAGE and esRAGE have been proposed as biomarkers for many diseases. However sRAGE and esRAGE levels are elevated in diabetes and chronic renal diseases and still tissue injury occurs. It is possible that increases in levels of AGEs are greater than increases in the levels of soluble receptors in these two diseases. Some new parameters have to be used which could be an universal biomarkers for cell dysfunction. It is hypothesized that increases in serum levels of AGEs are greater than the increases in the soluble receptors, and that the levels of AGEs is correlated with soluble receptors and that the ratios of AGEs/sRAGE, AGEs/esRAGE and AGEs/cRAGE are elevated in patients with end-stage renal disease (ESRD) and would serve as an universal risk marker for ESRD. The study subject comprised of 88 patients with ESRD and 20 healthy controls. AGEs, sRAGE and esRAGE were measured using commercially available enzyme linked immune assay kits. cRAGE was calculated by subtracting esRAGE from sRAGE. The data show that the serum levels of AGEs, sRAGE, cRAGE are elevated and that the elevation of AGEs was greater than those of soluble receptors. The ratios of AGEs/sRAGE, AGEs/esRAGE and AGEs/cRAGE were elevated and the elevation was similar in AGEs/sRAGE and AGEs/cRAGE but greater than AGEs/esRAGE. The sensitivity, specificity, accuracy, and positive and negative predictive value of AGEs/sRAGE and AGEs/cRAGE were 86.36 and 84.88 %, 86.36 and 80.95 %, 0.98 and 0.905, 96.2 and 94.8 %, and 61.29 and 56.67 % respectively. There was a positive correlation of sRAGE with esRAGE and cRAGE, and AGEs with esRAGE; and negative correlation between sRAGE and AGEs/sRAGE, esRAGE and AGES/esRAGE, and cRAGE and AGES/cRAGE. In conclusion, AGEs/sRAGE, AGEs/cRAGE and AGEs/esRAGE may serve as universal risk biomarkers for ESRD and that AGEs/sRAGE and AGEs/cRAGE are better risk biomarkers than AGEs/esRAGE.

PMID- 27714576 TI - Comparison of the Adipose and Luminal Mammary Gland Compartment as Orthotopic Inoculation Sites in a 4T1-Based Immunocompetent Preclinical Model for Triple Negative Breast Cancer. AB - Breast tumorigenesis is classically studied in mice by inoculating tumor cells in the fat pad, the adipose compartment of the mammary gland. Alternatively, the mammary ducts, which constitute the luminal mammary gland compartment, also provide a suitable inoculation site to induce breast cancer in murine models. The microenvironments in these compartments influence tumor cell progression, yet this effect has not been investigated in an immunocompetent context. Here, we compared both mammary gland compartments as distinct inoculation sites, taking into account the immunological aspect by inoculating 4T1 tumor cells in immunocompetent mice. Following tumor cell inoculation in the adipose compartment of non-pretreated/naive, hormonally pretreated/naive and non-pretreated/lactating mice, the primary tumors developed similarly. However, a slower onset of primary tumor growth was found after inoculations in the luminal compartment of non pretreated/lactating mice. Despite this difference in tumor development rate, metastasis to the liver and lungs was equally observed and was accompanied by lymphatic spreading of tumor cells and progressive splenomegaly with both inoculation types. Chitinase 3-like 1 (CHI3L1) and lipocalin 2 (LCN2) served as innovative biomarkers for disease progression showing increased levels in primary tumors and sera of the non-pretreated/lactating inoculation groups. A slower increase in circulating CHI3L1 but not LCN2 levels, was observed after inoculations in the luminal compartment which corroborated the slower tumor development at this inoculation site. Our results highlight the critical impact of different mammary gland compartments on tumor development in syngeneic murine models and support the use of novel tumor progression biomarkers in an immune competent environment. PMID- 27714580 TI - Diabetes and Bone Marrow Adiposity. AB - PURPOSE OF REVIEW: This study aims to describe bone marrow fat changes in diabetes and to discuss the potential role of marrow fat in skeletal fragility. RECENT FINDINGS: Advances in non-invasive imaging have facilitated marrow fat research in humans. In contrast to animal studies which clearly demonstrate higher levels of marrow fat in diabetes, human studies have shown smaller and less certain differences. Marrow fat has been reported to correlate with A1c, and there may be a distinct marrow lipid saturation profile in diabetes. Greater marrow fat is associated with impaired skeletal health. Marrow fat may be a mediator of skeletal fragility in diabetes. Circulating lipids, growth hormone alterations, visceral adiposity, and hypoleptinemia have been associated with greater marrow fat and may represent potential mechanisms for the putative effects of diabetes on marrow fat, although other factors likely contribute. Additional research is needed to further define the role of marrow fat in diabetic skeletal fragility and to determine whether marrow fat is a therapeutic target. PMID- 27714582 TI - Galactose alters markers of oxidative stress and acetylcholinesterase activity in the cerebrum of rats: protective role of antioxidants. AB - We evaluated the in vitro effects of galactose at 0.1, 3.0, 5.0 and 10.0 mM on thiobarbituric acid-reactive substances (TBA-RS), total sulfhydryl content, protein carbonyl content, on the activities of the antioxidant enzymes catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and on acetylcholinesterase (AChE) activity in the cerebral cortex, cerebellum and hippocampus of rats. We also investigated the influence of the antioxidants (each at 1 mM), alpha-tocopherol, ascorbic acid and glutathione, on the effects elicited by galactose on the parameters tested. Results showed that galactose, at a concentration of 3.0 mM, enhanced TBA-RS levels in the hippocampus, cerebral cortex and cerebellum of rats. In the cerebral cortex, galactose at concentrations of 5.0 and 10.0 mM increased TBA-RS and protein carbonyl content, and at 10.0 mM increased CAT activity and decreased AChE activity. In the cerebellum, galactose at concentrations of 5.0 and 10.0 mM increased TBA-RS, SOD and GSH-Px activities. In the hippocampus, galactose at concentrations of 5.0 and 10.0 mM increased TBA-RS and CAT activity and at 10.0 mM decreased GSH-Px. Data showed that at the pathologically high concentration (greater than 5.0 mM), galactose induces lipid peroxidation, protein carbonylation, alters antioxidant defenses in the cerebrum, and also alters cholinesterase activity. Trolox, ascorbic acid and glutathione addition prevented the majority of alterations in oxidative stress parameters and the decrease in AChE activity that were caused by galactose. Our findings lend support to a potential therapeutic strategy for this condition, which may include the use of appropriate antioxidants for ameliorating the damage caused by galactose. PMID- 27714581 TI - Finite Element-Based Mechanical Assessment of Bone Quality on the Basis of In Vivo Images. AB - Beyond bone mineral density (BMD), bone quality designates the mechanical integrity of bone tissue. In vivo images based on X-ray attenuation, such as CT reconstructions, provide size, shape, and local BMD distribution and may be exploited as input for finite element analysis (FEA) to assess bone fragility. Further key input parameters of FEA are the material properties of bone tissue. This review discusses the main determinants of bone mechanical properties and emphasizes the added value, as well as the important assumptions underlying finite element analysis. Bone tissue is a sophisticated, multiscale composite material that undergoes remodeling but exhibits a rather narrow band of tissue mineralization. Mechanically, bone tissue behaves elastically under physiologic loads and yields by cracking beyond critical strain levels. Through adequate cell orchestrated modeling, trabecular bone tunes its mechanical properties by volume fraction and fabric. With proper calibration, these mechanical properties may be incorporated in quantitative CT-based finite element analysis that has been validated extensively with ex vivo experiments and has been applied increasingly in clinical trials to assess treatment efficacy against osteoporosis.

AB - The hypothalamus controls metabolism, stress responses, and instinctive behaviors for individual survival and species preservation. Recent studies suggest that hypothalamic neurons retain plasticity throughout adulthood, which enables these neurons to respond to various kinds of changes in environment, nutrients, and fluctuating hormones. One of the mechanisms underlying the regulation of neural plasticity is the formation of a stable extracellular matrix (ECM) structure called perineuronal nets (PNNs). PNNs are large aggregates of heterogeneous ECM molecules such as chondroitin sulfate proteoglycans (CSPGs), hyaluronan, their link proteins, and tenascin-R. PNNs surround the cell body and proximal dendrites of a subset of neurons and limit adult neural plasticity. This review describes the CSPG-based ECM, including the PNNs, with a special focus on the hypothalamus of mice. We first provide an overview of PNNs in terms of their structure, molecular components, and functions, most of which have been demonstrated by extrahypothalamic studies. Second, we show the presence or absence of PNNs within individual hypothalamic regions and then describe non-PNN-formed ECM containing CSPGs that can be observed in particular hypothalamic regions. Finally, we will introduce a newly identified mouse hypothalamic area that we named the perifornical area of the anterior hypothalamus (PeFAH), which contains a cluster of PNN-positive neurons. PeFAH neurons express enkephalin and have bidirectional connections with the lateral septum. The anterior hypothalamus and lateral septum are thought to regulate defensive behaviors; therefore, the PeFAH neurons and PNNs around them could be involved in the regulation of defensive behaviors.

PMID- 27714584 TI - Contemporary management of ST-segment elevation myocardial infarction. AB - ST-elevation myocardial infarction (STEMI), which constitutes nearly 25-40 % of current acute myocardial infarction (AMI) cases, is a medical emergency that requires prompt recognition and treatment. Since the 2013 STEMI practice guidelines, a wealth of additional data that may further advance optimal STEMI practices has emerged. These data highlight the importance of improving patient treatment and transport algorithms for STEMI from non-primary percutaneous coronary intervention (PCI) centers. In addition, a focus on the reduction of total pain-to-balloon (P2B) times rather than simply door-to-balloon (D2B) times may further improve outcomes after primary PCI for STEMI. The early administration of newer oral P2Y12 inhibitors, including crushed forms of these agents for faster absorption, represents another treatment advancement. Recent data also suggest avoiding concurrent morphine use due to interactions with P2Y12 inhibitors. Furthermore, new technological advancements and investigational therapies, including Bioresorbable Vascular Scaffolds and the use of pre intervention intravenous microbubbles with transthoracic ultrasound, hold promise to play a useful role in future STEMI care. Despite these advancements, the prompt recognition of STEMI, at both the patient and health care system level, remains the cornerstone of optimal treatment. PMID- 27714586 TI - FCG (FLIPI, Charlson comorbidity index, and histological grade) score is superior to FLIPI in advanced follicular lymphoma. AB - The Follicular Lymphoma International Prognostic Index (FLIPI) is widely used in the identification of risk groups among follicular lymphoma (FL) patients. The aim of the present study was to evaluate the prognostic value of FLIPI combined with the Charlson comorbidity index (CCI) and histological grade of lymphoma. 224 newly diagnosed FL patients (median age 56 years) treated with immunochemotherapy were retrospectively analysed. Low FLIPI had 21.0 % of patients, intermediate 28.1 % and high 46.9 %. 50.9 % of patients had no comorbidities. Only 7.1 % of patients had a high CCI score (>=2), while 25.9 % of patients were histological grade 3. Parameters that influenced overall survival were evaluated using Cox regression analysis, in which CCI, FLIPI and histological grade (p < 0.05) retained prognostic significance. By combining these parameters, we have developed the FCG score, which incorporates FLIPI, CCI, and histological grade. This score defines three risk categories (low: 41.5 %; intermediate: 37.5 %; high: 13.4 %), associated with significantly different survival (p < 0.0001); this consequently improves discriminative power by 9.1 % compared to FLIPI. FCG score represents a possible new prognostic index, highlighting the role of the patient's clinical state and the histological characteristics of disease, as indicated by comorbidity index and histological grade of lymphoma. PMID- 27714588 TI - Cancer Screening Among Patients Who Self-Identify as Muslim: Combining Self Reported Data with Medical Records in a Family Practice Setting. AB - Cancer screening is a core component of family medicine but screening inequalities are well documented in Canada for foreign-born persons. Although people of Muslim faith and culture are the fastest growing immigrant population in Canada, there is little information in the literature about their cancer screening practices. Determining screening gaps could inform practice-based quality improvement initiatives. We conducted a retrospective chart review combining patient-level medical record data with self-reported religious affiliation to examine the relationship between religion and cancer screening in a large multi-site urban family practice. Religious affiliation was classified as Muslim, other affiliation, or atheist/no religious affiliation. 5311 patients were included in the study sample. Muslim patients were significantly less likely to prefer English for spoken communication than the other two groups, less likely to be Canadian-born, more likely to have a female family physician, and were over represented in the lowest income quintile. Muslim women were most likely to be up to-date on breast cancer screening (85.2 vs. 77.5 % for those with other religions vs. 69.5 % for those with no religious affiliation). There were no significant differences in cancer screening by physician sex. In this pilot study conducted within a primary care practice, we used self-reported data on religious affiliation to examine possible inequities in cancer screening and observed intriguing variations in screening by self-identified religious affiliation. Future efforts to collect and use similar patient-level data should incorporate non-official languages and intensively outreach to patients with less health system contact. Regardless, the family medicine context may be the ideal setting to collect and act on patient-level sociodemographic data such as religious affiliation. PMID- 27714587 TI - Japanese phase II study of rituximab maintenance for untreated indolent B-cell non-Hodgkin lymphoma with high tumor burden. AB - Recent large-scale randomized clinical trials in Europe and the US demonstrated that maintenance therapy with rituximab significantly improved the progression free survival (PFS) in indolent B-cell non-Hodgkin lymphoma (B-NHL) patients, especially those with follicular lymphoma (FL). However, rituximab maintenance has not been approved in Japan, because there are no clinical data supporting the benefit of rituximab maintenance in Japanese patients. Therefore, we conducted a single-arm, multicenter bridging study in previously untreated indolent B-NHL patients with high tumor burden. The primary endpoint was 4-year PFS and was expected to be 70 % based on previous studies. Sixty-two patients, including 55 FL patients, were enrolled and received induction therapy with CHOP combined with rituximab (R-CHOP). Fifty-eight patients responding to R-CHOP induction received rituximab at 375 mg/m2 every 8 weeks for 2 years as for the rituximab maintenance arm in the PRIMA study. A 4-year PFS of 69.8 % was obtained (95 % confidence interval 55.9-80.0 %). Rituximab maintenance was well tolerated and common adverse events were infections, neutropenia, and/or leukopenia that were manageable with conventional supportive care. No patients died. These data were compatible with the PRIMA data. R-CHOP induction followed by rituximab is useful in Japanese patients with untreated indolent B-NHL having high tumor burden. Clinical trial number UMIN000001191. PMID- 27714589 TI - Expression of Two Novel beta-Glucosidases from Chaetomium atrobrunneum in Trichoderma reesei and Characterization of the Heterologous Protein Products. AB - Two novel GH3 family thermostable beta-glucosidases from the filamentous fungus Chaetomium atrobrunneum (CEL3a and CEL3b) were expressed in Trichoderma reesei, purified by two-step ion exchange chromatography, and characterized. Both enzymes were active over a wide range of pH as compared to Neurospora crassa beta glucosidase GH3-3, which was also expressed in T. reesei and purified. The optimum temperature of both C. atrobrunneum enzymes was around 60 degrees C at pH 5, and both enzymes had better thermal and pH stability and higher resistance to metallic compounds and to glucose inhibition than GH3-3. They also showed higher activity against oligosaccharides composed of glucose units and linked with beta-1,4-glycosidic bonds and moreover, had higher affinity for cellotriose over cellobiose. In hydrolysis tests against Avicel cellulose and steam-exploded sugarcane bagasse, performed at 45 degrees C, particularly the CEL3a enzyme performed similarly to N. crassa GH3-3 beta-glucosidase. Taking into account the thermal stability of the C. atrobrunneum beta-glucosidases, they both represent promising alternatives as enzyme mixture components for improved cellulose saccharification at elevated temperatures. PMID- 27714590 TI - Technical and clinical validation of three commercial real-time PCR kits for the diagnosis of neuroborreliosis in cerebrospinal fluid on three different real-time PCR platforms. AB - This study reports the evaluation of the technical and clinical validation of the O-DiaBorburg kit (DIA), Borrelia burgdorferi PCR kit, ISEX (GENE), and Borrelia burgdorferi sensu lato Real-TM (SAC) for the diagnosis of neuroborreliosis in cerebrospinal fluid based on both Borrelia DNA and CSF samples from patients with clinical suspicion of neuroborreliosis. This validation study was done by analysing the kits on the Rotorgene Q (RGQ), CFX96, and LightCycler480 (LC480). For all kits, the linear range was larger on RGQ than on CFX96 and LC480. A good reproducibility was obtained for all assays on all instruments. Storage at -20 degrees C resulted in a decreased reproducibility for SAC. Results of the limit of detection (LOD95) experiments indicated a better sensitivity than described in the kit insert for all kits on all PCR platforms. No cross-reactivity was found for genetically related organisms nor for other pathogens which may be present in CSF. All species of the Borrelia burgdorferi sensu lato complex were detected with the GENE and SAC kits. The DIA kit failed to detect B. lusitaniae. The results seemed to indicate a better overall performance for the GENE kit on RGQ. However, its diagnostic value could not be confirmed in the clinical validation study, wherein none of the 103 CSF samples from clinical neuroborreliosis cases showed a positive real-time PCR result with the GENE kit analysed on RGQ. PMID- 27714591 TI - Mitogen-activated protein kinases (MAPKs) are modulated during Francisella tularensis infection, but inhibition of extracellular-signal-regulated kinases (ERKs) is of limited therapeutic benefit. AB - Francisella tularensis is a Gram-negative intracellular bacterium that causes the disease tularemia. The disease can be fatal if left untreated and there is currently no licenced vaccine available; the identification of new therapeutic targets is therefore required. Toll-like receptors represent an interesting target for therapeutic modulation due to their essential role in generating immune responses. In this study, we analysed the in vitro expression of the key mitogen-activated protein kinases (MAPKs) p38, JNK and ERK in murine alveolar macrophages during infection with F. tularensis. The phosphorylation profile of ERK highlighted its potential as a target for therapeutic modulation and subsequently the effect of ERK manipulation was measured in a lethal intranasal F. tularensis in vivo model of infection. The selective ERK1/2 inhibitor PD0325901 was administered orally to mice either pre- or post-challenge with F. tularensis strain LVS. Both treatment regimens selectively reduced ERK expression, but only the pre-exposure treatment produced decreased bacterial burden in the spleen and liver, which correlated with a significant reduction in the pro-inflammatory cytokines IFN-gamma, MCP-1, IL-6, and TNF-alpha. However, no overall improvements in survival were observed for treated animals in this study. ERK may represent a useful therapeutic target where selective dampening of the immune response (to control the damaging pathology seen during infection) is combined with antibiotic treatment required to eradicate bacterial infection. This combination treatment strategy has been shown to be effective in other models of tularemia. PMID- 27714592 TI - Characteristics of cefazolin inoculum effect-positive methicillin-susceptible staphylococcus aureus infection in a multicentre bacteraemia cohort. AB - Cefazolin treatment failure has been observed in high-inoculum infections caused by methicillin-susceptible Staphylococcus aureus (MSSA) with a cefazolin inoculum effect (CIE). However, data on the characteristics and risk factors for the acquisition of CIE-positive MSSA infection are scarce. CIE positivity was measured as an MIC >= 16 MUg/ml with a high inoculum (~5 * 107 CFU/ml). The blaZ gene type was assessed through sequence analysis. The clinical characteristics and risk factors for the acquisition of CIE-positive MSSA infection were assessed. The association between the antimicrobial susceptibility profile and CIE positivity was evaluated. A total of 303 MSSA bacteraemia cases and their corresponding isolates were collected from ten hospitals: 61 (20.1 %) isolates showed a positive CIE; 254 (83.8 %) were positive for the blaZ gene. No significant association was found between CIE positivity and the site of infection. Metastatic cancer (aOR 2.86, 95 % CI, 1.10-7.48) and recent (<=1 month) close contact with a chronically ill patient (aOR 4.69, 95 % CI, 1.76 12.50) were identified as significant risk factors for CIE-positive MSSA infection through multivariate analyses. Resistances to clindamycin (OR 3.55, 95 % CI, 1.62-7.80) and erythromycin (OR 5.00, 95 % CI, 2.50-9.99) were associated with CIE positivity, presenting high specificity (92.9 %) and a negative predictive value (82.3 %). CIE-positive MSSA constituted approximately one-fifth of MSSA bacteraemia cases. Although CIE positivity was not clinically discernible, CIE positivity was associated with clindamycin or erythromycin susceptibility. Therefore, our findings suggest that cefazolin can be used in the treatment of high-inoculum MSSA infection if the isolates are susceptible to clindamycin or erythromycin. PMID- 27714593 TI - Emergence of New Delhi metallo-beta-lactamase 1 and other carbapenemase-producing Acinetobacter calcoaceticus-baumannii complex among patients in hospitals in Ha Noi, Viet Nam. AB - Acinetobacter baumannii is an important cause of multidrug-resistant hospital acquired infections in the world. Here, we investigate the presence of NDM-1 and other carbapenemases among carbapenem-resistant A. baumannii isolated between August 2010 and December 2014 from three large hospitals in Hanoi, Vietnam. We identified 23/582 isolates (4 %) (11 from hospital A, five from hospital B, and seven from hospital C) that were NDM-1 positive, and among them 18 carried additional carbapenemase genes, including seven isolates carrying NDM-1, IMP-1, and OXA-58 with high MICs for carbapenems. Genotyping indicated that NDM-1 carrying A. baumannii have expanded clonally in these hospitals. Five new STs (ST1135, ST1136, ST1137, ST1138, and ST1139) were identified. One isolate carried NDM-1 on a plasmid belonging to the N-repA replicon type; no NDM-1-positive plasmids were identified in the other isolates. We have shown the extent of the carbapenem resistance and the local clonal spread of A. baumannii carrying NDM-1 in these hospitals; coexistence of NDM-1 and IMP-1 is reported for the first time from Vietnam here, and this will further seriously limit future therapeutic options. PMID- 27714594 TI - Rapid diagnostic test and use of antibiotic against methicillin-resistant Staphylococcus aureus in adult intensive care unit. AB - Ventilator-associated pneumonia (VAP) due to methicillin-resistant Staphylococcus aureus (MRSA) is associated with excess mortality and costs. Molecular biology test allows rapid identification of MRSA in sputum with high negative predictive value. We hypothesized that use of a rapid diagnostic test in patients with suspected VAP was associated with reduced use of antibiotics directed against MRSA. This retrospective, observational study was conducted in a polyvalent intensive care unit (ICU) of a university hospital. We compared two periods: before (2007-2010) and after (2010-2015) the implementation of a rapid diagnostic test, which uses RT-PCR to detect pathogens in 60 minutes. The primary endpoint was the effect on the empirical use of anti-MRSA antibiotics. The second endpoint was the effect of this strategy on the cost regarding antibiotic treatment. The first group included 120 suspected VAP (88 patients) and the second group 121 suspected VAP (89 patients). Empirical use of vancomycin and linezolid decreased by 50 % between the two periods. Twenty-seven VAP (22 %) were treated with an anti-MRSA treatment between 2007 and 2010, and 13 (11 %) between 2010 and 2015 (p = 0.04). The mean cost of anti-MRSA treatment by patients in the first group was 63 +/- 223 ?, and 13 +/- 52 ? in the second group (p < 0.001). This study shows that a rapid diagnostic test was associated with reduced use and cost of anti MRSA antibiotics in patients with suspected VAP. These results should be confirmed by further multicenter prospective studies. PMID- 27714595 TI - Calcipotriol Plus Betamethasone Dipropionate Aerosol Foam is Effective, Independent of Body Mass Index and the Extent and Severity of Psoriasis. AB - INTRODUCTION: Good treatment adherence is important in the effective management of psoriasis and is related to both the frequency of applications and the amount of product used versus the recommended dose. The efficacy and safety of fixed combination calcipotriol 50 ug/g (Cal) and betamethasone 0.5 mg/g as dipropionate (BD) in the treatment of psoriasis is well established; an aerosol foam formulation has been developed to enhance adherence. This subanalysis from the Phase III PSO-FAST study evaluates the amount of Cal/BD foam used during treatment and the association between the extent and severity of baseline disease. METHODS: Patients (>=18 years) with mild-to-severe body psoriasis were randomized 3:1 to once-daily Cal/BD foam or vehicle. The amount of Cal/BD foam and vehicle used over the 4-week study period was evaluated according to three baseline disease assessments: extent of body surface area (BSA) affected by psoriasis, physician's global assessment of disease severity (PGA) and modified psoriasis area and severity index (mPASI). Treatment success and mPASI75 rates were assessed according to body mass index (BMI) and body weight. RESULTS: 323 patients were randomized to Cal/BD foam and 103 to vehicle. At week 4, the mean total amount of Cal/BD foam used was 120.8 g (n = 293), which was similar to the amount of vehicle used (128.9 g; n = 98). The total amount of Cal/BD foam used at week 4 was greater with increasing BSA and increasing severity of baseline PGA and mPASI. Throughout the study, 93.1% of patients in the Cal/BD foam group and 99.0% of patients in the vehicle group missed <=10% of treatment applications. Treatment success and mPASI75 rates were generally similar when stratified according to BMI and body weight. CONCLUSIONS: This subanalysis demonstrates that Cal/BD aerosol foam is used appropriately and is effective for the treatment of psoriasis, independent of BMI and the extent or severity of disease.

PMID- 27714596 TI - Analysis of the Appendicularia class (subphylum Urochordata) as a possible tool for biomonitoring four estuaries of the tropical region. AB - This study aims to characterize the differences between physical and chemical parameters of water quality indicators and eutrophication in four estuaries of the state of Rio de Janeiro and relate them to full density of the species that belong to the Appendicularia class with the purpose of seeking bioindicators for estuarine areas. The estuaries studied were from the rivers Macae, Sao Joao, Bracui, and Pereque-Acu. The physicochemical parameters monitored for evaluation of the water bodies and used for the correlation with the appendicularians were pH, temperature, nitrite, nitrate, N-ammonia, total nitrogen, phosphate, total phosphorus, dissolved oxygen (DO), suspended particulate matter (SPM), chlorophyll a, heterotrophic bacteria, and fecal coliform. The estuaries Bracui and Sao Joao showed enhanced qualities of water and lower degrees of eutrophication than Macae and Pereque-Acu estuaries. The species of the Appendicularia class found in this study were Oikopleura longicauda (Vogt, 1854), Oikopleura dioica Fol, 1872, Oikopleura fusiformis Fol, 1872, and Fritillaria haplostoma Fol, 1872. The density of appendicularians and O. longicauda was inversely related to the nutrient values and SPM; nonetheless, no species of appendicularians could be used as a bioindicator of any estuary in the current study. Studies on the quality of estuary waters and the search for other bioindicators belonging to other zooplankton groups are recommended to confirm the obtained results and to expand the knowledge of these coastal environments. PMID- 27714598 TI - ? PMID- 27714597 TI - Biomonitoring and exposure assessment of people living near or working at an Italian waste incinerator: methodology of the SPoTT study. AB - Only few studies on the health effect of waste incinerators were focused on human biomonitoring (HBM). Our aim is to describe a protocol for assessing early variation of selected items in a population group living close to a waste incinerator in Turin, Italy. A cohort of 394 subjects was randomly selected, among residents near the incinerator and residents far from it. To achieve this sample size, 765 subjects were contacted. The cohort was monitored before the start-up of the plant and will be followed up 1 and 3 years after, with measurements of respiratory function, selected blood and urine parameters including 19 metals, 17 congeners of PCDDs/Fs, 12 congeners of DL-PCBs, 30 congeners of NDL-PCBs, 11 OH-PAHs, specific hormones (T3, T4, TSH, cortisol and ACTH) and common health parameters. The same protocol is applied for plant workers and breeders living near the plant. Individual exposure to urban pollution and waste incinerator fallout were assessed through the use of mathematical models. Information on individual habits was assessed using a specific questionnaire. SPoTT is the first Italian study that adopts a longitudinal design of appropriate statistical power to assess health impacts of waste incinerator plants' emission. The initial results comparing the baseline to the first follow-up are due at the end of 2016. PMID- 27714599 TI - The influence of reported ADHD and substance abuse on suicidal ideation in a non clinical sample of young men. AB - This study intended to determine whether former and current ADHD symptomatology is associated with suicidal ideation in a non-clinical sample of 18 year old males. We performed a cross sectional descriptive study of 3280 men during the examination for military service. The investigation included a screening for substance abuse, past (WURS) and current (ADHD symptom checklist) ADHD symptomatology and an interview about suicidal ideations. We found a correlation of suicidal ideations with a history of ADHD symptomatology. ADHD symptoms were strongly consistent over time. These results indicate that a history of (diagnosed or undiagnosed) ADHD could be a predictor for suicidal ideations. Surveying a history of ADHD in primary care might help identify subjects at risk for suicidal tendencies. PMID- 27714600 TI - [End of a psychiatric era? : Impact on the use of mechanical restraints after prohibition of psychiatric cage beds in a regional psychiatric department in Vienna, Austria]. AB - BACKGROUND: Since June 1st, 2014 the use of cage beds, a physical coercive measure in psychiatric wards, is forbidden by Austrian law. The 3rd Psychiatric Department at the Otto Wagner Hospital in Vienna carried out a pilot-study prior to the application of this law and compared 6 months with and 6 months without the use of cage beds in psychiatric acute treatment. The investigation focused on the use of mechanical restraints, especially of 4-point-restraints at admission time. METHODS: The study collected clinical and epidemiological data from the patients and analyzed interviews taken with patients and staff-members after the use of coercive measures. RESULTS: The prohibition of cage beds was associated with a relative increase of the use of 4-point-restraints. Time spent in 4-point restraints is less than time spent in the cage beds. A trend could also be observed by a decrease of time spent in 4-point-restraints. Data from the interviews showed that there was no preference by patients of either kind of physical restraint. They strongly urged for more personal talks and non-physical and non-pharmacological therapies during admission. CONCLUSIONS: Team members required more human resources for the treatment of these acute psychiatric patients. PMID- 27714601 TI - Intravascular imaging comparison of two metallic limus-eluting stents abluminally coated with biodegradable polymers: IVUS and OCT results of the DESTINY trial. AB - We sought to compare, by means of IVUS and OCT imaging, the performance of a novel sirolimus-eluting drug-eluting stent (DES) with biodegradable polymer (InspironTM) to the BiomatrixTM DES. From the DESTINY trial, a total of 70 randomized patients (2:1) were enrolled in the IVUS substudy (InspironTM, n = 46; BiomatrixTM: n = 20) while 25 patients were evaluated with OCT (InspironTM, n = 19; BiomatrixTM: n = 06) at 9-month follow-up. The main endpoints were % of neointimal tissue obstruction (IVUS) and neointimal stut coverage (OCT) at 9 months. Patients treated with both DES had very little NIH formation at 9 months either by IVUS (% of NIH obstruction of 4.9 +/- 4.1 % with InspironTM vs. 2.7 +/- 2.9 % with BiomatrixTM, p = 0.03) or by OCT (neointimal thickness of 144.2 +/- 72.5 um InspironTM vs. 115.0 +/- 53.9 um with BiomatrixTM, p = 0.45). Regarding OCT strut-level assessment, again both devices showed excellent 9-month performance, with high rates of strut coverage (99.49 +/- 1.01 % with InspironTM vs. 97.62 +/- 2.21 % with BiomatrixTM, p < 0.001) and very rare malapposition (0.29 +/- 1.06 % with InspironTM vs. 0.53 +/- 0.82 % with BiomatrixTM, p = 0.44). Patients with any uncovered struts were more frequently identified in the BiomatrixTM group (9.78 +/- 7.13 vs. 2.29 +/- 3.91 %, p < 0.001). In the present study, midterm IVUS and OCT evaluations showed that both new generation DES with biodegradable polymer were effective in terms of suppressing excessive neointimal response, with very high rates of apposed and covered struts, suggesting a consistent and benign healing pattern.

PMID- 27714602 TI - Reference ranges and determinants of right ventricle outflow tract acceleration time in healthy adults by two-dimensional echocardiography. AB - The right ventricular outflow tract acceleration time (RVOT-AT) has shown to progressively shorten with increasing degrees of pulmonary pressure. However, the physiologic ranges of RVOT AT are based on small sample sizes and have not been investigated regarding their determining factors. The aim of this study was to investigate reference values and determining factors of RVOT-AT in a large population of healthy subjects and by values described in the literature. In the first part of the study, 1029 healthy subjects (mean age 45.6 +/- 16.0 years, 565 (54.7 %) females) were prospectively assessed by clinical examination including demography, vital signs and echocardiography. In the second part, we performed a pooled analysis of eight published studies describing RVOT-AT in healthy subjects (n = 450). Statistical analysis included the calculation of 5 % quantiles for defining reference values. RVOT-AT significantly but weakly correlated with age (r: -0.207; p < 0.001), body mass Index (r: -0.16), systolic (r: -0.158) and diastolic (r: -0.137) blood pressure, heart rate (r: -0.197) and left ventricular (LV) E/A ratio (r: 0.229) (all p < 0.001). No differences were found with regards to sex. In a synopsis of both prospective and literature-based data sets, RVOT-AT weighted means was 138.51 ms and the 5 % quantile was 104.7 ms (95 % confidence interval 98.2-110.1). This study delineates the range of RVOT-AT in healthy adults and it's determining factors. Our study is in line with the cut-off value stated by the European guidelines with an RVOT-AT <=105 ms denoting abnormal values. PMID- 27714604 TI - Improving education and coping of scoliosis patients undergoing surgery, and their families, using e-health. AB - PURPOSE: Healthcare providers have limited time to spend with scoliosis patients who are considering surgery and their families. The purpose of this study was to evaluate an e-health strategy to increase knowledge and coping in patients with scoliosis who are surgical candidates and their families. METHODS: We enrolled patients with scoliosis who were candidates for surgery and their families. Patients and their families completed the scoliosis knowledge questionnaire, meaning of illness questionnaire, social support and coping questionnaires before and after access to a comprehensive evidence-based scoliosis website ( http://www.aboutkidshealth.ca/scoliosis ). RESULTS: Seventy-four patients and 71 parents completed the evaluation. While both patients and parents improved their knowledge of scoliosis (p = 0.001 and p = 0.003, respectively), the scores of patients were consistently lower than those of the parents both before and after website use (p = 0.0001). Only parents demonstrated a change in the meaning of illness questionnaire, with a small increase in the negative attitude towards illness and a small decrease in the positive attitude towards illness (p = 0002 and p = 0.01, respectively). Of the 12 coping methods examined on the Adolescent Coping Orientation for Problem Experiences (A-COPE) instrument, patients were slightly more likely than parents to use relaxing and solving family problems as tools to cope following website access (p = 0.02 and p = 0.09, respectively). Parents demonstrated no significant changes in the four methods of coping on the Coping Health Inventory for Parents (CHIP) after website exposure. While the majority of patients and parents reported receiving sufficient support, over half of the patients indicated a need for more support in social participation. CONCLUSION: An evidence-based website increased the knowledge of patients and parents but simply providing access to the website had minimal impact on their coping and perceptions of social support. The website, however, provides users with the opportunity to absorb vital information about scoliosis across several media. PMID- 27714605 TI - Effect of left atrial volume and pulmonary vein anatomy on outcome of nMARQTM catheter ablation of paroxysmal atrial fibrillation. AB - PURPOSE: Left atrial volume (LA) and pulmonary vein (PV) anatomy may potentially relate to technical challenges in achieving stable and effective catheter position in case of atrial fibrillation (AF) ablation by means of "one-shot" catheters. The aim of this study was to investigate whether LA volume and PV anatomy, evaluated by computed tomography (CT) or magnetic resonance (MR) prior to ablation, predict acute and midterm outcome of AF ablation by nMARQTM. METHODS: We included 75 patients (mean age 58 +/- 11 years, 67 % male) with symptomatic paroxysmal AF. All patients underwent CT/MR scanning prior to catheter ablation to evaluate LA volume and PV anatomy. All the patients underwent PV isolation by nMARQTM, an open-irrigated mapping and radiofrequency (RF) decapolar ablation catheter. Ablation was guided by electroanatomic mapping allowing RF energy delivery in the antral region of PVs from ten irrigated electrodes simultaneously. RESULTS: Mean LA volume was 75 +/- 40 ml. A normal anatomy (4 PVs) was documented in 40 (53 %) patients and abnormal anatomy (common truncus or accessory PVs) in 35 patients. Mean procedural and fluoroscopy times were 94 +/- 55 and 8 +/- 5 min, respectively, without significant differences among patients with normal or abnormal anatomy (92 +/- 45 vs 95 +/- 64 min, p = 0.85 and 6 +/- 3 vs 8 +/- 4 min, p = 0.65, respectively). Mean ablation time was 14 +/- 3 min, and 99 % of the targeted veins were isolated with a mean of 23 +/- 5 RF pulses per patient. After a mean follow-up of 17 +/- 8 months, 23 (31 %) patients had an atrial arrhythmia recurrence. Neither LA volume nor PV anatomy was a predictor of outcome. CONCLUSIONS: LA volume and PV anatomy did not affect procedural data and outcome in patients who underwent PV isolation by an open irrigated mapping and RF decapolar ablation catheter.

AB - Fusions of elastin-like peptide (ELP) purification tags and self-cleaving inteins provide a powerful platform for purifying tagless recombinant proteins without the need for conventional packed-bed columns. A drawback to this method has been premature cleaving of the ELP tag during expression, before the purification procedure can take place. Here we demonstrate a split-intein method, where the self-cleaving intein is divided into two inactive segments during expression and purification. Spontaneous assembly of the purified intein segments then restores self-cleaving activity to deliver the tagless target protein. PMID- 27714606 TI - Affinity Purification of Proteins in Tag-Free Form: Split Intein-Mediated Ultrarapid Purification (SIRP). AB - Proteins purified using affinity-based chromatography often exploit a recombinant affinity tag. Existing methods for the removal of the extraneous tag, needed for many applications, suffer from poor efficiency and/or high cost. Here we describe a simple, efficient, and potentially low-cost approach-split intein-mediated ultrarapid purification (SIRP)-for both the purification of the desired tagged protein from Escherichia coli lysate and removal of the tag in less than 1 h. The N- and C-fragment of a self-cleaving variant of a naturally split DnaE intein from Nostoc punctiforme are genetically fused to the N-terminus of an affinity tag and a protein of interest (POI), respectively. The N-intein/affinity tag is used to functionalize an affinity resin. The high affinity between the N- and C fragment of DnaE intein enables the POI to be purified from the lysate via affinity to the resin, and the intein-mediated C-terminal cleavage reaction causes tagless POI to be released into the flow-through. The intein cleavage reaction is strongly inhibited by divalent ions (e.g., Zn2+) under non-reducing conditions and is significantly enhanced by reducing conditions. The POI is cleaved efficiently regardless of the identity of the N-terminal amino acid except in the cases of threonine and proline, and the N-intein-functionalized affinity resin can be regenerated for multiple cycles of use. PMID- 27714608 TI - Intracellular Production of Cyclic Peptide Libraries with SICLOPPS. AB - Cyclic peptides are an important class of molecules that are increasingly viewed as an ideal scaffold for inhibition of protein-protein interactions (PPI). Here we detail an approach that enables the intracellular synthesis of cyclic peptide libraries of around 108 members. The method utilizes split intein mediated circular ligation of peptides and proteins (SICLOPPS), taking advantage of split intein splicing to cyclize a library of peptide sequences. SICLOPPS allows the ring size, set residues and number of random residues within a library to be predetermined by the user. SICLOPPS libraries have been combined with a variety of cell-based screens to identify cyclic peptide inhibitors of a variety of enzymes and protein-protein interactions. PMID- 27714609 TI - Recombinant Expression of Cyclotides Using Split Inteins. AB - Cyclotides are fascinating microproteins (~30 residues long) present in several families of plants that share a unique head-to-tail circular knotted topology of three disulfide bridges, with one disulfide penetrating through a macrocycle formed by the two other disulfides and inter-connecting peptide backbones, forming what is called a cystine knot topology. Naturally occurring cyclotides have shown to posses various pharmacologically relevant activities and have been reported to cross cell membranes. Altogether, these features make the cyclotide scaffold an excellent molecular framework for the design of novel peptide-based therapeutics, making them ideal substrates for molecular grafting of biological peptide epitopes. In this chapter we describe how to express a native folded cyclotide using intein-mediated protein trans-splicing in live Escherichia coli cells. PMID- 27714610 TI - Ribosomal Synthesis of Thioether-Bridged Bicyclic Peptides. AB - Many biologically active peptides found in nature exhibit a bicyclic structure wherein a head-to-tail cyclic backbone is further constrained by an intramolecular linkage connecting two side chains of the peptide. Accordingly, methods to access macrocyclic peptides sharing this overall topology could be of significant value toward the discovery of new functional entities and bioactive compounds. With this goal in mind, we recently developed a strategy for enabling the biosynthesis of thioether-bridged bicyclic peptides in living bacterial cells. This method involves a split intein-catalyzed head-to-tail cyclization of a ribosomally produced precursor peptide, combined with inter-sidechain cross linking through a genetically encoded cysteine-reactive amino acid. This approach can be applied to direct the formation of structurally diverse bicyclic peptides with high efficiency and selectivity in living Escherichia coli cells and provides a platform for the generation of combinatorial libraries of genetically encoded bicyclic peptides for screening purposes. PMID- 27714611 TI - Preparation of Semisynthetic Peptides Macrocycles Using Split Inteins. AB - Cyclic peptides are highly desired molecules not only for basic research but also for many biomedical and pharmacological applications. Due to their potentially superior physicochemical properties as compared to their linear counterparts, they are considered as ideal candidates for studying protein-protein interactions, among others. Most of the methods developed in recent years to prepare cyclic peptides focus either on a synthetic or a recombinant route. While the former provides access to diversified, noncanonical peptides, including unnatural and D-amino acid, for example, the latter can harness the power of genetic randomization to generate and select from large peptide libraries. Only few approaches have been reported to prepare semisynthetic macrocycles that would benefit from both the advantages associated with synthetic and genetically encoded parts. We describe in this chapter a chemo-enzymatic method to make semisynthetic cyclic peptides in vitro from two fragments using protein trans splicing and bioorthogonal oxime ligation. PMID- 27714612 TI - Semisynthesis of Membrane-Attached Proteins Using Split Inteins. AB - The site-selective installation of lipid modifications on proteins is critically important in our understanding of how membrane association influences the biophysical properties of proteins as well as to study certain proteins in their native environment. Here, we describe the use of split inteins for the C-terminal attachment of lipid-modified peptides to virtually any protein of interest (POI) via protein trans-splicing (PTS). To achieve this, the protein of interest is expressed in fusion with the N-terminal split intein segment and the C-terminal split intein segment is prepared by solid phase peptide synthesis. A synthetic peptide carrying two lipid chains is also made chemically to serve as a membrane anchor and subsequently linked to the C-terminal split intein by native chemical ligation. Proteins of interest for our work are the prion protein as well as small GTPases; however, extensions to other POIs are possible. Detailed information for the C-terminal introduction of a lipidated membrane anchor (MA) peptide using split intein systems from Synechocystis spp. and Nostoc punctiforme for the Prion protein (PrP, as a challenging protein of interest) and the enhanced green-fluorescent protein (eGFP, as an easily trackable target protein) are provided here. PMID- 27714613 TI - Protein Chemical Modification Inside Living Cells Using Split Inteins. AB - Methods to visualize, track, measure, and perturb or activate proteins in living cells are central to biomedical efforts to characterize and understand the spatial and temporal underpinnings of life inside cells. Although fluorescent proteins have proven to be extremely useful for in vivo studies of protein function, their utility is inherently limited because their spectral and structural characteristics are interdependent. These limitations have spurred the creation of alternative approaches for the chemical labeling of proteins. We describe in this protocol the use of fluorescence resonance emission transfer (FRET)-quenched DnaE split-inteins for the site-specific labeling and concomitant fluorescence activation of proteins in living cells. We have successfully employed this approach for the site-specific in-cell labeling of the DNA binding domain (DBD) of the transcription factor YY1 using several human cell lines. Moreover, we have shown that this approach can be also used for modifying proteins in order to control their cellular localization and potentially alter their biological activity. PMID- 27714614 TI - Segmental Isotopic Labeling of Proteins for NMR Study Using Intein Technology. AB - Segmental isotopic labeling of samples for NMR studies is attractive for large complex biomacromolecular systems, especially for studies of function-related protein-ligand interactions and protein dynamics (Goto and Kay, Curr Opin Struct Biol 10:585-592, 2000; Rosa et al., Molecules (Basel, Switzerland) 18:440, 2013; Hiroaki, Expert Opin Drug Discovery 8:523-536, 2013). Advantages of segmental isotopic labeling include selective examination of specific segment(s) within a protein by NMR, significantly reducing the spectral complexity for large proteins, and allowing for the application of a variety of solution-based NMR strategies. By utilizing intein techniques (Wood and Camarero, J Biol Chem 289:14512-14519, 2014; Paulus, Annu Rev Biochem 69:447-496, 2000), two related approaches can generally be used in the segmental isotopic labeling of proteins: expressed protein ligation (Muir, Annu Rev Biochem 72:249-289, 2003) and protein trans-splicing (Shah et al., J Am Chem Soc 134:11338-11341, 2012). Here, we describe general implementation and latest improvements of expressed protein ligation method for the production of segmental isotopic labeled NMR samples. PMID- 27714615 TI - Segmental Isotope Labeling of Insoluble Proteins for Solid-State NMR by Protein Trans-Splicing. AB - Solid-state NMR spectroscopy (ssNMR) is uniquely suited for atomic-resolution structural investigations of large protein assemblies, which are notoriously difficult to study due to their insoluble and non-crystalline nature. However, assignment ambiguities because of limited resolution and spectral crowding are currently major hurdles that quickly increase with the length of the polypeptide chain. The line widths of ssNMR signals are independent of proteins size, making segmental isotope labeling a powerful approach to overcome this limitation. It allows a scalable reduction of signal overlap, aids the assignment of repetitive amino acid sequences, and can be easily combined with other selective isotope labeling strategies. Here we present a detailed protocol for segmental isotope labeling of insoluble proteins using protein trans-splicing. Our protocol exploits the ability of many insoluble proteins, such as amyloid fibrils, to fold correctly under in vitro conditions. In combination with the robust trans splicing efficiency of the intein DnaE from Nostoc punctiforme, this allows for high yields of segmentally labeled protein required for ssNMR analysis. PMID- 27714616 TI - Split-Intein Triggered Protein Hydrogels. AB - Proteins are nature's building blocks and indispensable in living organisms. Protein-based hydrogels have a wide variety of applications in research and biotechnology. In this chapter, we describe an intein-mediated protein hydrogel that utilizes two synthetic soluble protein block copolymers, each containing a subunit of a trimeric protein that serves as a cross-linker and one half of the naturally split DnaE intein from Nostoc punctiforme. Mixing of these two protein block copolymers initiates an intein trans-splicing reaction that constitutes a self-assembling polypeptide flanked by cross-linkers, triggering protein hydrogel formation. The generated hydrogels are highly stable under both acidic and basic conditions, and at temperatures up to 50 degrees C. In addition, these hydrogels are able to undergo rapid reassembly after shear-induced rupture. Incorporation of an appropriate binding motif into the protein block copolymers enables the convenient site-specific incorporation of functional globular proteins into the hydrogel network. PMID- 27714617 TI - A Recessive Pollination Control System for Wheat Based on Intein-Mediated Protein Splicing. AB - A transgene-expression system for wheat that relies on the complementation of inactive precursor protein fragments through a split-intein system is described. The N- and C-terminal fragments of a barnase gene from Bacillus amyloliquifaciens were fused to intein sequences from Synechocystis sp. and transformed into wheat plants. Upon translation, both barnase fragments are assembled by an autocatalytic intein-mediated trans-splicing reaction, thus forming a cytotoxic enzyme. This chapter focuses on the use of introns and flexible polypeptide linkers to foster the expression of a split-barnase expression system in plants. The methods and protocols that were employed with the objective to test the effects of such genetic elements on transgene expression and to find the optimal design of expression vectors for use in wheat are provided. Split-inteins can be used to form an agriculturally important trait (male sterility) in wheat plants. The use of this principle for the production of hybrid wheat seed is described. The suggested toolbox will hopefully be a valuable contribution to future optimization strategies in this commercially important crop. PMID- 27714618 TI - Conditional Toxin Splicing Using a Split Intein System. AB - Protein toxin splicing mediated by split inteins can be used as a strategy for conditional cell ablation. The approach requires artificial fragmentation of a potent protein toxin and tethering each toxin fragment to a split intein fragment. The toxin-intein fragments are, in turn, fused to dimerization domains, such that addition of a dimerizing agent reconstitutes the split intein. These chimeric toxin-intein fusions remain nontoxic until the dimerizer is added, resulting in activation of intein splicing and ligation of toxin fragments to form an active toxin. Considerations for the engineering and implementation of conditional toxin splicing (CTS) systems include: choice of toxin split site, split site (extein) chemistry, and temperature sensitivity. The following method outlines design criteria and implementation notes for CTS using a previously engineered system for splicing a toxin called sarcin, as well as for developing alternative CTS systems. PMID- 27714619 TI - Photocontrol of the Src Kinase in Mammalian Cells with a Photocaged Intein. AB - Recently developed methods that can photochemically control protein activities and functions in live cells have opened up new opportunities for studying signaling networks at the cellular and subcellular levels. Our laboratory has reported a genetically encoded photoactivatable intein, which allows the direct photocontrol of primary sequences of proteins, and consequently, their activities and functions in live mammalian cells. Herein, we provide details on experimental design and the utilization of this photocaged intein to photoactivate the Src tyrosine kinase in human embryonic kidney (HEK) 293T cells. The described procedures may be adopted to photocontrol other proteins in other types of mammalian cells. PMID- 27714620 TI - LOV2-Controlled Photoactivation of Protein Trans-Splicing. AB - Protein trans-splicing is a posttranslational modification that joins two protein fragments together via a peptide a bond in a process that does not require exogenous cofactors. Towards achieving cellular control, synthetically engineered systems have used a variety of stimuli such as small molecules and light. Recently, split inteins have been engineered to be photoactive by the LOV2 domain (named LOVInC). Herein, we discuss (1) designing of LOV2-activated target proteins (e.g., inteins), (2) selecting feasible splice sites for the extein, and (3) imaging cells that express LOVInC-based target exteins. PMID- 27714621 TI - A Cassette Approach for the Identification of Intein Insertion Sites. AB - Over the past decade split inteins have established themselves as powerful tools for protein engineering, protein semisynthesis, and protein functional control approaches. Their key advantage lies in the protein trans-splicing (PTS) reaction that enables posttranslational protein assembly from two independent, even synthetic, peptide precursors. However, since most split intein applications deal with fragmentation and modification of proteins, various issues can arise, ranging from reduced stability to impairment of protein folding. In this chapter I address how the usage of DNA encoded intein cassettes can streamline and speed up the identification of functional split intein insertion sites in novel proteins of interest (POI). PMID- 27714622 TI - Computational Prediction of New Intein Split Sites. AB - Split inteins have emerged as a powerful tool in protein engineering. We describe a reliable in silico method to predict viable split sites for the design of new split inteins. A computational circular permutation (CP) prediction method facilitates the search for internal permissive sites to create artificial circular permutants. In this procedure, the original amino- and carboxyl-termini are connected and new termini are created. The identified new terminal sites are promising candidates for the generation of new split sites with the backbone opening being tolerated by the structural scaffold. Here we show how to integrate the online usage of the CP predictor, CPred, in the search of new split intein sites.

AB - Background The inappropriate use of systemic antifungal agents can result in unnecessary exposure, adverse events, increased microbial resistance and increased costs. Aim This study analysed the use of systemic antifungal agents and adherence to treatment guidelines for fungal infections. Setting A Brazilian tertiary hospital. Methods This cross-sectional study investigated 183 patients who were treated with systemic antifungals. Antifungal drugs were classified according to the fourth level of the Anatomical Therapeutic Chemical classification system. The appropriateness of treatments was analysed with respect to the indication, dose and potential drug-drug interactions. Descriptive and univariate statistical analyses were performed. The main outcome measure was the frequency of adherence to treatment guidelines for fungal infections. Results The number of established treatments was 320, with 163 (50.9 %) pre-emptive, 63 (19.7 %) targeted, 56 (17.5 %) empirical and 38 (11.9 %) prophylactic treatments. The overall adherence to the treatment guidelines was 29.4 %. The proportion of appropriate treatment considering indication, dosage and drug-drug interactions was 84.1, 67.8 and 47.2 %, respectively. The most commonly prescribed systemic antifungal agents were fluconazole in 170 (53.1 %), voriconazole in 43 (13.4 %) and amphotericin B deoxycholate in 36 (11.3 %) cases. Conclusion The study showed a low proportion of appropriate antifungal drug use; the dosage and drug-drug interactions criteria were the determining factors for the high percentage of non adherence to treatment guidelines in the hospital. The profile of antifungal agents used showed the predominance of fluconazole as well as the use of new antifungal drugs. PMID- 27714627 TI - Non-graduation after comprehensive school, and early retirement but not unemployment are prominent in childhood cancer survivors-a Finnish registry-based study. AB - BACKGROUND: In order to assess neurocognitive and social outcomes after childhood cancer, we explored the educational and vocational attainments of Finnish survivors in comparison to matched population controls. METHODS: From national registries, we identified survivors (n = 3243) born from 1960 to 1992 and aged below 16 at cancer diagnosis (years 1964-2009) as well as their controls (n = 16,215). Data on educational achievements, yearly income, employment status, and retirement were retrieved from Statistics Finland. RESULTS: The median (range) age at study was 28 (17-50) years. The proportion of those with no education after comprehensive school was higher than controls for all the diagnostic groups: brain tumor (BT) (33.5 vs 23.0 %), solid tumor (ST) (25.0 vs 21.4 %), and leukemia/NHL (29.2 vs 23.1 %). Odds ratios (OR) for unemployment were not significantly elevated in any survivor group compared to controls, but OR for being retired was elevated in each survivor group (BT 14.8, ST 2.2, leukemia/NHL 4.0). Irradiation significantly increased that OR only in BT survivors. Leukemia/NHL survivors treated after 1992 had lower risk for early retirement (OR 0.6) compared to those diagnosed earlier. CONCLUSIONS: Survivors had higher frequencies than controls for lacking further education after comprehensive school. Unemployment was not common, but risk for early retirement was significantly increased in each three survivor group. IMPLICATIONS FOR CANCER SURVIVORS: Reassuring is that premature retirement was less common during the most recent treatment era. Screening and follow-up of psychosocial performance more effectively might be essential, and there is a need for studies on possibility for effective rehabilitation of the survivors.

AB - Ebola virus is a pathogen responsible for a severe disease that affects humans and several animal species. To date, the natural reservoir of this virus is not known with certainty, although it is believed that fruit bats (Chiroptera: Pteropodidae) play an important role in maintaining the virus in nature. Although information on viral transmission from animals to humans is not clear, the role of arthropods has come under suspicion. In this article, we review the potential role of arthropods in spreading Ebola virus, acting as mechanical or biological vectors. PMID- 27714629 TI - Discriminative Stimulus Effects of Abused Inhalants. AB - Inhalants are a loosely organized category of abused compounds defined entirely by their common route of administration. Inhalants include volatile solvents, fuels, volatile anesthetics, gasses, and liquefied refrigerants, among others. They are ubiquitous in modern society as ingredients in a wide variety of household, commercial, and medical products. Persons of all ages abuse inhalants but the highest prevalence of abuse is in younger adolescents. Although inhalants have been shown to act upon a host of neurotransmitter receptors, the stimulus effects of the few inhalants which have been trained or tested in drug discrimination procedures suggest that their discriminative stimulus properties are mediated by a few key neurotransmitter receptor systems. Abused volatile solvent inhalants have stimulus effects that are similar to a select group of GABAA positive modulators comprised of benzodiazepines and barbiturates. In contrast the stimulus effects of nitrous oxide gas appear to be at least partially mediated by uncompetitive antagonism of NMDA receptors. Finally, volatile anesthetic inhalants have stimulus effects in common with both GABAA positive modulators as well as competitive NMDA antagonists. In addition to a review of the pharmacology underlying the stimulus effects of inhalants, the chapter also discusses the scientific value of utilizing drug discrimination as a means of functionally grouping inhalants according to their abuse-related pharmacological properties. PMID- 27714630 TI - Low-Intensity Ultrasound Decreases alpha-Synuclein Aggregation via Attenuation of Mitochondrial Reactive Oxygen Species in MPP(+)-Treated PC12 Cells. AB - Many studies have shown that mitochondrial dysfunction and the subsequent oxidative stress caused by excessive reactive oxygen species (ROS) generation play a central role in the pathogenesis of Parkinson's disease (PD). We have previously shown that low-intensity ultrasound (LIUS) could reduce ROS generation by L-buthionine-(S,R)-sulfoximine (BSO) in retinal pigment epithelial cells. In this study, we studied the effects of LIUS stimulation on the ROS-dependent alpha synuclein aggregation in 1-methyl-4-phenylpyridinium ion (MPP+)-treated PC12 cells. We found that LIUS stimulation suppressed the MPP+-induced ROS generation and inhibition of mitochondrial complex I activity in PC12 cells in an intensity dependent manner at 30, 50, and 100 mW/cm2. Furthermore, LIUS stimulation at 100 mW/cm2 suppressed inhibition of mitochondrial complex activity by MPP+ and actually resulted in a decrease of alpha-synuclein phosphorylation and aggregation induced by MMP+ treatment in PC12 cells. LIUS stimulation also inhibited expression of casein kinase 2 (CK2) that appears to mediate ROS dependent alpha-synuclein aggregation. Finally, LIUS stimulation alleviated the death of PC12 cells by MPP+ treatment in an intensity-dependent manner. We, hence, suggest that LIUS stimulation inhibits ROS generation by MPP+ treatment, thereby suppressing alpha-synuclein aggregation in PC12 cells. PMID- 27714631 TI - Creatine Prevents Corticosterone-Induced Reduction in Hippocampal Proliferation and Differentiation: Possible Implication for Its Antidepressant Effect. AB - The benefits of creatine supplementation have been reported in a broad range of central nervous system diseases, including depression, although the mechanisms underlying these effects remain to be understood. In the present study, we investigated the ability of creatine to counteract the morphological and behavioral effects elicited by chronic administration of corticosterone (CORT, 20 mg/kg, p.o.) for 21 days to mice, a pharmacological model of depression that mimics exposure to stress. CORT treatment increased immobility time in the tail suspension test (TST) and forced swim test (FST), as well as latency to immobility in the FST, and decreased the sucrose consumption in the sucrose preference test (SPT). These behavioral effects were associated with decreased hippocampal cell proliferation and neuronal differentiation and increased glial fibrillary acid protein (GFAP) immunostaining (suggestive of astrogliosis) in dentate gyrus (DG) of the hippocampus. These CORT-induced alterations were abolished by treatment with either fluoxetine (a conventional antidepressant) or creatine for 21 days (both 10 mg/kg, p.o.). In addition, fluoxetine, but not creatine, was able to reverse the CORT-induced reduction in serum CORT levels. Collectively, our results suggest that creatine produces morphological alterations that contribute to the improvement of depressive-like behaviors triggered by chronic CORT administration in mice. PMID- 27714632 TI - Semaphorin 7A as a Potential Therapeutic Target for Multiple Sclerosis. AB - Semaphorin 7A (sema7A) is classified as an immune semaphorin with dual functions in the immune system and in the central nervous system (CNS). These molecules are of interest due to their potential role in multiple sclerosis (MS), which is a chronic demyelinating and neurodegenerative disease of autoimmune origin. In this study, we elucidated the role of sema7A in neuroinflammation using both in vitro and in vivo experimental models. In an in vitro model of neuroinflammation, using cerebellar organotypic slice cultures, we observed that challenge with lipopolysaccharide (LPS) endotoxin did not affect demyelination or cell death in sema7A-deficient cultures compared to wild-type cultures. Moreover, the in vivo outcome of experimental autoimmune encephalomyelitis (EAE) in sema7A-deficient mice was altered in an antigen- and adjuvant-dose-dependent manner, while no differences were observed in the wild-type counterparts. Altogether, these results indicate that sema7A is involved in peripheral immunity and CNS inflammation in MS pathogenesis. Indeed, these data suggest that sema7A might be a potential therapeutic target to treat MS and autoimmune conditions. PMID- 27714633 TI - Hypoxic and Reoxygenated Microenvironment: Stemness and Differentiation State in Glioblastoma. AB - Glioblastoma (GBM) is the most common and aggressive primary malignant brain tumor in adults. Hypoxia is a distinct feature in GBM and plays a significant role in tumor progression, resistance to treatment, and poor outcome. However, there is lack of studies relating type of cell death, status of Akt phosphorylation on Ser473, mitochondrial membrane potential, and morphological changes of tumor cells after hypoxia and reoxygenation. The rat glioma C6 cell line was exposed to oxygen deprivation (OD) in 5 % fetal bovine serum (FBS) or serum-free media followed by reoxygenation (RO). OD induced apoptosis on both 5 % FBS and serum-free groups. Overall, cells on serum-free media showed more profound morphological changes than cells on 5 % FBS. Moreover, our results suggest that OD combined with absence of serum provided a favorable environment for glioblastoma dedifferentiation to cancer stem cells, since nestin, and CD133 levels increased. Reoxygenation is present in hypoxic tumors through microvessel formation and cell migration to oxygenated areas. However, few studies approach these phenomena when analyzing hypoxia. We show that RO caused morphological alterations characteristic of cells undergoing a differentiation process due to increased GFAP. In the present study, we characterized an in vitro hypoxic microenvironment associated with GBM tumors, therefore contributing with new insights for the development of therapeutics for resistant glioblastoma. PMID- 27714634 TI - Zinc Oxide Nanoparticle Induces Microglial Death by NADPH-Oxidase-Independent Reactive Oxygen Species as well as Energy Depletion. AB - Zinc oxide nanoparticle (ZnO-NP) is one of the most widely used engineered nanoparticles. Upon exposure, nanoparticle can eventually reach the brain through various routes, interact with different brain cells, and alter their activity. Microglia is the fastest glial cell to respond to any toxic insult. Nanoparticle exposure can activate microglia and induce neuroinflammation. Simultaneous to activation, microglial death can exacerbate the scenario. Therefore, we focused on studying the effect of ZnO-NP on microglia and finding out the pathway involved in the microglial death. The present study showed that the 24 h inhibitory concentration 50 (IC50) of ZnO-NP for microglia is 6.6 MUg/ml. Early events following ZnO-NP exposure involved increase in intracellular calcium level as well as reactive oxygen species (ROS). Neither of NADPH oxidase inhibitors, apocynin, (APO) and diphenyleneiodonium chloride (DPIC) were able to reduce the ROS level and rescue microglia from ZnO-NP toxicity. In contrary, N-acetyl cysteine (NAC) showed opposite effect. Exogenous supplementation of superoxide dismutase (SOD) reduced ROS significantly even beyond control level but partially rescued microglial viability. Interestingly, pyruvate supplementation rescued microglia near to control level. Following 10 h of ZnO-NP exposure, intracellular ATP level was measured to be almost 50 % to the control. ZnO-NP-induced ROS as well as ATP depletion both disturbed mitochondrial membrane potential and subsequently triggered the apoptotic pathway. The level of apoptosis-inducing proteins was measured by western blot analysis and found to be upregulated. Taken together, we have deciphered that ZnO-NP induced microglial apoptosis by NADPH oxidase-independent ROS as well as ATP depletion.

AB - Dishevelled (DVL/Dvl) genes play roles in canonical and noncanonical Wnt signaling, both of which are essential in neural tube closing and are involved in balancing neural progenitor growth and differentiation, or neuroepithelial cell polarity, respectively. In mouse Dvl haploinsufficiency leads to neural tube defects (NTDs), which represent the second most common birth defects. However, DVL genes' genetic contributions in human NTDs are modest. We sought to explore the molecular impact on such genes in human NTDs in a Han Chinese cohort. In 47 cases with NTDs and 61 matched controls, in brain tissues, the DVL1/2 mRNA levels were correlated with the levels of a serine/threonine protein kinase MARK2, and in 20 cases with lumbosacral spina bifida, the mRNA levels of DVL1 and MARK2 were significantly decreased; by contrast, only an intronic rare variant was found. Moreover, in an extended population, we found merely three novel rare missense variants in 1 % of individuals with NTDs. In cell-based assays, Mark2 depletion indeed reduces Dvl gene expression and interrupts neural stem cell (NSCs) growth and differentiation, which are likely to be mediated through a decrease in class IIa HDAC phosphorylation and reduced H3K4ac and H3K27ac occupancies at the Dvl1/2 promoters. Finally, the detections of folate concentration in human brain tissue and NSCs and MEF cells indicates that folate deficiency contributes to the observed decreases in Mark2 and Dvl1 expression. Our present study raises a potential common pathogenicity mechanism in human lumbosacral spina bifida about DVL genes rather than their genetic pathogenic role.

AB - Four uncharacterized omega-transaminases (omegaTAs) from Pseudomonas putida NBRC 14164 have been identified and cloned from the pool of fully sequenced genomes. The genes were functionally expressed in Escherichia coli BL21, and the enzymes were purified and characterized. Four TAs showed highly (S)-selective omegaTA activity and converted (S)-alpha-methylbenzylamine and pyruvate to acetophenone and L-Ala. The maximum activity of cloned enzymes was in the pH range of 8.0-8.5 (Pp36420), 8.5-9.5 (Pp21050), 9.0-9.5 (PpspuC), and 9.5-10.5 (PpbauA), and the optimal temperatures were at 35 degrees C (Pp36420, Pp21050, and PpspuC) and 50 degrees C (PpbauA), respectively, with K M of 161.3 mM (Pp21050), 136.7 mM (PpbauA), 398.5 mM (Pp36420), and 130.9 mM (PpspuC) and yielding a catalytic efficiency k cat/K M of 0.015, 0.003, 0.012, and 0.023 mM-1 s-1. Several racemic amines and amino alcohols were resolved by the cloned omegaTAs; perfect conversions (48-50 %) were obtained by at least one enzyme, and the residual substrates were left with 97-99 % ee. Kinetic resolution of racemic phenylglycinol was done with PpspuC in a 100-mL scale. Enaniomeric excess of (S) phenylglycinol reached 99 % with 45 % isolated yield. The high enantioselectivity and large substrate spectra of the cloned PpTAs showed an attractive potency for biotechnology application in production of chiral amines and amino alcohols. PMID- 27714637 TI - Headaches: a Review of the Role of Dietary Factors. AB - Dietary triggers are commonly reported by patients with a variety of headaches, particularly those with migraines. The presence of any specific dietary trigger in migraine patients varies from 10 to 64 % depending on study population and methodology. Some foods trigger headache within an hour while others develop within 12 h post ingestion. Alcohol (especially red wine and beer), chocolate, caffeine, dairy products such as aged cheese, food preservatives with nitrates and nitrites, monosodium glutamate (MSG), and artificial sweeteners such as aspartame have all been studied as migraine triggers in the past. This review focuses the evidence linking these compounds to headache and examines the prevalence of these triggers from prior population-based studies. Recent literature surrounding headache related to fasting and weight loss as well as elimination diets based on serum food antibody testing will also be summarized to help physicians recommend low-risk, non-pharmacological adjunctive therapies for patients with debilitating headaches. PMID- 27714635 TI - Mitochondria-Associated Membranes (MAMs): Overview and Its Role in Parkinson's Disease. AB - Mitochondria-associated membranes (MAMs) are structures that regulate physiological functions between endoplasmic reticulum (ER) and mitochondria in order to maintain calcium signaling and mitochondrial biogenesis. Several proteins located in MAMs, including those encoded by PARK genes and some of neurodegeneration-related proteins (huntingtin, presenilin, etc.), ensure this regulation. In this regard, MAM alteration is associated with neurodegenerative diseases such as Parkinson's (PD), Alzheimer's (AD), and Huntington's diseases (HD) and contributes to the appearance of the pathogenesis features, i.e., autophagy dysregulation, mitochondrial dysfunction, oxidative stress, and lately, neuronal death. Moreover,, ER stress and/or damaged mitochondria can be the cause of these disruptions. Therefore, ER-mitochondria contact structure and function are crucial to multiple cellular processes. This review is focused on the molecular interaction between ER and mitochondria indispensable to MAM formation and on MAM alteration-induced etiology of neurodegenerative diseases. PMID- 27714640 TI - Cloning and Characterization of Cold-Adapted alpha-Amylase from Antarctic Arthrobacter agilis. AB - In this study, the gene encoding an alpha-amylase from a psychrophilic Arthrobacter agilis PAMC 27388 strain was cloned into a pET-28a(+) vector and heterologously expressed in Escherichia coli BL21(DE3). The recombinant alpha amylase with a molecular mass of about 80 kDa was purified by using Ni2+-NTA affinity chromatography. This recombinant alpha-amylase exhibited optimal activity at pH 3.0 and 30 degrees C and was highly stable at varying temperatures (30-60 degrees C) and within the pH range of 4.0-8.0. Furthermore, alpha-amylase activity was enhanced in the presence of FeCl3 (1 mM) and beta mercaptoethanol (5 mM), while CoCl2 (1 mM), ammonium persulfate (5 mM), SDS (10 %), Triton X-100 (10 %), and urea (1 %) inhibited the enzymatic activity. Importantly, the presence of Ca2+ ions and phenylmethylsulfonyl fluoride (PMSF) did not affect enzymatic activity. Thin layer chromatography (TLC) analysis showed that recombinant A. agilis alpha-amylase hydrolyzed starch, maltotetraose, and maltotriose, producing maltose as the major end product. These results make recombinant A. agilis alpha-amylase an attractive potential candidate for industrial applications in the textile, paper, detergent, and pharmaceutical industries. PMID- 27714639 TI - Caralluma umbellata Peroxidase: Biochemical Characterization and Its Detoxification Potentials in Comparison with Horseradish Peroxidase. AB - Caralluma umbellata peroxidase (CUP) is an acidic heme-containing protein having a molecular weight of ~42 kDa and is specific to guaiacol. It is not a glycoprotein. It was purified to 12.5-fold purity with 6.16 % yield. Its activity is dependent on hydrogen peroxide and has an optimum pH and temperature of 6.2 and 45 degrees C respectively. It can decolorize dyes, viz., Aniline Blue, Reactive Black 5, and Reactive Blue 19 but not Congo Red, while HRP can decolorize Congo Red also. It has lignin-degrading potentiality as it can decompose veratryl alcohol. Detoxification of phenol was more by CUP compared to HRP while with p-nitrophenol HRP has a greater detoxification rate. Based on our results, CUP was identified to be capable of oxidizing a variety of hazardous substances and also a lignin-degrading plant biocatalyst. PMID- 27714641 TI - Economic Growth, Climate Change, and Obesity. AB - Human and planetary health as well as economic growth are firmly interlinked and subject to complex interaction effects. In this paper, we provide an overview of interlinkages between economic growth, climate change, and obesity focusing on recent advances in the literature. In addition to empirical findings, we discuss different theoretical frameworks used to conceptualize these complex links and highlight policy options and challenges. We conclude that policies addressing both climate change and obesity simultaneously are particularly promising and often suitable for ensuring sustainable development. PMID- 27714642 TI - Role of New Antiplatelet Drugs on Cardiovascular Disease: Update on Cangrelor. AB - Dual therapy with a P2Y12 receptor antagonist in addition to aspirin is the antiplatelet treatment of choice in patients with acute coronary syndromes or undergoing percutaneous coronary intervention (PCI). However, available oral P2Y12 antagonists have several limitations, mostly due to their pharmacological profile, which can affect outcomes in certain clinical settings. Cangrelor is an intravenous, direct-acting, potent P2Y12 inhibitor with rapid onset and offset of action, which has been recently approved for clinical use in patients undergoing PCI. In clinical trials, cangrelor has demonstrated greater efficacy than clopidogrel with a favorable safety profile among PCI patients not receiving pretreatment with oral P2Y12 antagonists. However, its definitive role in contemporary practice is yet to be determined. This review aims to provide a comprehensive overview of the current status of knowledge on cangrelor, focusing on its pharmacological properties, clinical development, and the potential applications of this newly available agent. PMID- 27714643 TI - Transarterial Chemoembolization for the Treatment of Advanced-Stage Hepatocellular Carcinoma. AB - It remains controversial whether transarterial chemoembolization (TACE) should be performed in patients with advanced-stage hepatocellular carcinoma (HCC). The present large retrospective cohort study aimed to define the survival outcome following TACE of advanced HCC and to identify the prognostic factors. Five hundred eight patients with Barcelona Clinic Liver Cancer (BCLC) C-stage HCC, Child-Pugh A/B who were treated with TACE between November 1998 and December 2013 were identified. There was no significant difference in overall survival (OS) between patients with Eastern Cooperative Oncology Group (ECOG) 0 and those with ECOG >=1 (10.5 months vs. 11.9 months, P = 0.87). The median OS of patients without portal vein tumor thrombosis (PVTT) was longer than that of patients with PVTT (16.9 vs. 6.1 months, P < 0.001). Child-Pugh B class, PVTT, extrahepatic metastasis, tumor size >=5 cm, number of tumors >=3, and alpha-fetoprotein >=400 ng/dL were significantly associated with decreased survival and were used for determining the risk scores. All patients were divided into two groups (low-risk and high-risk groups) according to the cutoff value of 6.5 for risk scores. The patients with a value <6.5 (low-risk group) had significantly longer survival than those with >6.5 (high-risk group) (24.1 vs. 7.5 months, respectively; P < 0.001). TACE is an effective therapy for select patients with advanced stage HCC and may provide equal or improved survival as compared with reported outcomes with sorafenib. The results highlight the need for a differentiated approach to therapeutic recommendations for patients with BCLC C. PMID- 27714644 TI - Prognostic Value of Lymph Node Status and Extent of Lymphadenectomy in Pancreatic Neuroendocrine Tumors Confined To and Extending Beyond the Pancreas. AB - BACKGROUND: The impact of lymph node (LN) status and lymphadenectomy (LA) on survival in pancreatic neuroendocrine tumors (pNETs) remains controversial. We evaluated the impact of tumor extension and grade on nodal metastasis and survival. METHODS: Surgical pNET patients were queried in the Surveillance Epidemiology and End Results (SEER) database (1998-2012, N = 981). Factors associated with LN status were analyzed by logistic regression and by Cox analyses. RESULTS: For T1-T2 tumors, N status was associated only with tumor size. N status (p = 0.001), grade (p < 0.001), age (p = 0.001), and sex (p = 0.007) predicted overall survival (OS). For T3-T4, grade (p < 0.001), sex (p = 0.004), size (p = 0.013), and age (p = 0.007) but not N status (p = 0.789) predicted OS. For T1-T2, disease-specific survival (DSS; p = 0.003) and OS (p = 0.008) were longer for N0 vs N1, while N0 vs NX had similar OS (p = 0.59) and DSS (p = 0.80). While a difference was seen in DSS for NX vs N1 (p = 0.04), no significant difference in OS was seen (p = 0.08). For T3-T4, N status did not affect DSS (p = 0.365) or OS (p = 0.454). For all T groups and any N status, extended LA (>=10 nodes resected) was not associated with OS. CONCLUSION: While in T1-T2 pNET N1 status is a predictor of negative OS, similar outcome between NX and N0 supports limited LN resection in selected patients. Extended LA is unlikely to be helpful in T3-T4. PMID- 27714646 TI - Development of fistula between esophagogastric anastomotic site and cartilage portion of trachea after subtotal esophagectomy for cervical esophageal cancer: a case report. AB - A 65-year-old man with cT3N2M0 stage III cervical esophageal cancer underwent subtotal esophagectomy and gastric tube reconstruction through the retrosternal route after neoadjuvant chemoradiotherapy. The anastomosis was located adjacent to the left side of the trachea, and a circular stapler was used for anastomosis. Postoperative anastomotic leakage occurred, and an esophagotracheal fistula between the esophagogastric anastomotic site and cartilage portion of the trachea was observed on postoperative day 44. The patient underwent division of the fistula, direct suturing of the anastomotic leakage site, left pectoralis major muscle flap placement, and tracheotomy. He was discharged home on postoperative day 120 on an oral diet. All previous reports of tracheobronchial fistula describe the occurrence of the fistula at the membranous portion of the trachea. The formation of a fistula between the esophagogastric anastomotic site and cartilage portion of the trachea is considered a possible complication when a high esophagogastric anastomosis is created. PMID- 27714647 TI - Metastasis of colon cancer to the thyroid and cervical lymph nodes: a case report. AB - The incidence of thyroid metastasis among colorectal cancer patients is extremely rare. We report a case of colonic adenocarcinoma metastasis to the thyroid gland with treatment of lung and liver metastases, in a 61-year-old woman with a history of colon cancer. She showed a thyroid mass related to a 3-month history of hoarseness. Physical and imaging examinations disclosed a diffuse large thyroid mass with swollen cervical lymph nodes. Fine-needle aspiration cytology of the thyroid mass suggested malignancy. The patient underwent total thyroidectomy. Histopathological examination and immunohistochemical staining revealed adenocarcinoma, which was consistent with a diagnosis of metastases from primary colon cancer to the thyroid and cervical lymph nodes. At 2 years after thyroid surgery, the patient has been continuing outpatient chemotherapy for the lung and liver metastases. Thyroidectomy appeared to both relieve the patient and prevent local symptoms. PMID- 27714648 TI - Hereditary Hemorrhagic Telangiectasia (Osler-Weber-Rendu syndrome).

AB - Research on commensal microbiota and its contribution to health and disease is a new and very dynamically developing field of biology and medicine. Recent experimental and clinical investigations underscore the importance of gut microbiota in the pathogenesis and course of stroke. Importantly, microbiota may influence the outcome of cerebral ischemia by modulating central nervous system antigen-specific immune responses. In this review we summarize studies linking gut microbiota with physiological function and disorders of the central nervous system. Based on these insights we speculate about targeting the gut microbiome in order to treat stroke.

PMID- 27714649 TI - Telephone-Delivered Stepped Collaborative Care for Treating Anxiety in Primary Care: A Randomized Controlled Trial. AB - BACKGROUND: Collaborative care for depression is more effective in improving treatment outcomes than primary care physicians' (PCPs) usual care (UC). However, few trials of collaborative care have targeted anxiety. OBJECTIVE: To examine the impact and 12-month durability of a centralized, telephone-delivered, stepped collaborative care intervention (CC) for treating anxiety disorders across a network of primary care practices. DESIGN: Randomized controlled trial with blinded outcome assessments. PARTICIPANTS: A total of 329 patients aged 18-64 referred by their PCPs in response to an electronic medical record (EMR) prompt. They include 250 highly anxious patients randomized to either CC or to UC, and 79 moderately anxious patients who were triaged to a watchful waiting (WW) cohort and later randomized if their conditions clinically deteriorated. INTERVENTION: Twelve months of telephone-delivered CC involving non-mental health professionals who provided patients with basic psycho-education, assessed preferences for guideline-based pharmacotherapy, monitored treatment responses, and informed PCPs of their patients' care preferences and progress via the EMR. MAIN MEASURES: Mental health-related quality of life ([HRQoL]; SF-36 MCS); secondary outcomes: anxiety (Hamilton Anxiety Rating Scale [SIGH-A], Panic Disorder Severity Scale) and mood (PHQ-9). KEY RESULTS: At 12-month follow-up, highly anxious patients randomized to CC reported improved mental HRQoL (effect size [ES]: 0.38 [95 % CI: 0.13-0.63]; P = 0.003), anxiety (SIGH-A ES: 0.30 [0.05-0.55]; P = 0.02), and mood (ES: 0.45 [0.19-0.71] P = 0.001) versus UC. These improvements were sustained for 12 months among African-Americans (ES: 0.70-1.14) and men (ES: 0.43-0.93). Of the 79 WW patients, 29 % met severity criteria for randomization, and regardless of treatment assignment, WW patients reported fewer anxiety and mood symptoms and better mental HRQoL over the full 24-month follow-up period than highly anxious patients who were randomized at baseline. CONCLUSIONS: Telephone-delivered, centralized, stepped CC improves mental HRQoL, anxiety and mood symptoms. These improvements were durable and particularly evident among those most anxious at baseline, and among African-Americans and men.

PMID- 27714651 TI - Comparison of FOLFIRINOX Chemotherapy with Other Regimens in Patients with Biliary Tract Cancers: a Retrospective Study. AB - PURPOSE: The aim of this retrospective study was to compare the different treatment options of patients with advanced biliary tract carcinoma (BTC) who were treated with platinum-gemcitabine (CG) or platinum-5-fluorouracil (CF) or 5 Fluorouracil-oxaliplatin-irinotecan (FOLFIRINOX) chemotherapy. METHODS: We included the patients with advanced BTC who were registered at the Department of Oncology in Gaziantep University between January 2008 and January 2016. The following data were analyzed: disease control rate (DCR), progression free survival (PFS) of first and second-line of chemotherapy, and overall survival (OS). Kaplan-Meier method and Log-rank test was used to compare two survival curves, and hazard regression model was used to evaluate risk factors for PFS. RESULT: Ninety-two patients were recruited. 53 (57.6 %), 27 (29.3 %), and 12 (13 %) patients received CG, CF, and FOLFIRINOX regimen as first-line chemotherapy, respectively. Median PFS and DCR of CG group were 22 weeks and 56.6 %, and these were 12 weeks and 44.4 % for CF group, and 9 weeks and 41.7 % for FOLFIRINOX group. Median OS of CG, CF, and FOLFIRINOX groups was 28, 21,and 23.5 weeks, respectively (p = 0.497). Second-line PFS of fluoropyrimidine-based chemotherapy group and gemcitabine-based chemotherapy group was 12 vs. 14 weeks (p = 0.988). Second-line PFS of FOLFIRINOX was 20 weeks, whereas it was 14 weeks for other fuoropyrimidine-based chemotherapies (p = 0.190). CONCLUSIONS: This was the first study evaluating the FOLFIRINOX regimen in BTC. Cisplatin-gemcitabine therapy still provides better survival in BCT. However, FOLFIRINOX can be an option in the second-line treatment of BTC patients who are eligible for chemotherapy. PMID- 27714654 TI - Physical Activity, Endurance Exercise, and Excess-Can One Overdose? AB - OPINION STATEMENT: Although moderate levels of exercise reduce cardiovascular morbidity and mortality in the general population, recent data have questioned whether higher doses of physical activity are associated with diminished health benefits and adverse outcomes. This review focuses on several issues at the center of this controversy including epidemiologic data describing mortality trends in those who engage in high levels of physical activity and recent observational data suggesting adverse cardiovascular outcomes among long-term endurance athletes. Specifically for the endurance athlete, the evidence and limitations of the available data associating veteran endurance athletes with an increased risk of atrial fibrillation, pathologic, and arrhythmogenic cardiac remodeling and accelerated coronary atherosclerosis will be discussed. This review will also provide practitioners involved in the care of athletes and highly active patients a conceptual framework for these contemporary controversies and will highlight key areas of uncertainty that will require future research. PMID- 27714653 TI - Prognostic Impact of Neutrophil/Lymphocyte Ratio, Platelet Count, CRP, and Albumin Levels in Metastatic Colorectal Cancer Patients Treated with FOLFIRI Bevacizumab. AB - PURPOSE: Metastatic colorectal cancer (mCRC) is a lethal disease and fluorouracil leucovorin-irinotecan (FOLFIRI) plus bevacizumab (bev) is a standard approach. Hence, there is a strong need for identifying new prognostic factors to show the efficacy of FOLFIRI-bev. METHODS: This is a retrospective study including patients (n = 90) with mCRC from two centers in Turkey. Neutrophil/lymphocyte (N/L) ratio, platelet count, albumin, and C-reactive protein (CRP) were recorded before FOLFIRI-bev therapy. The efficacy of these factors on progression-free survival (PFS) was analyzed with Kaplan Meier and Cox regression analysis. And the cutoff value of N/L ratio was analyzed with ROC analysis. RESULTS: The median age was 56 years (range 21-80). Forty-seven percent of patients with N/L ratio >2.5 showed progressive disease versus 43 % in patients with N/L ratio <2.5 (p = 0.025). The median PFS was 8.1 months for the patients with N/L ratio >2.5 versus 13.5 months for the patients with N/L ratio <2.5 (p = 0.025). At univariate Cox regression analysis, high baseline neutrophil count, LDH, N/L ratio, and CRP were all significantly associated with poor prognosis. At multivariate Cox regression analysis, CRP was confirmed to be a better independent prognostic factor. CRP variable was divided into above the upper limit of normal (ULN) and normal value. The median PFSs of the patients with normal and above ULN were 11.3 versus 5.8 months, respectively (p = 0.022). CONCLUSIONS: CRP and N/L ratio are potential predictors for advanced mCRC treated with FOLFIRI-bev. PMID- 27714655 TI - Performance and microbial community structures of hydrolysis acidification process treating azo and anthraquinone dyes in different stages. AB - In this study, performance of hydrolysis acidification process treating simulated dyeing wastewater containing azo and anthraquinone dyes in different stages was investigated. The decolorization ratio, CODCr removal ratio, BOD5/CODCr value, and volatile fatty acids (VFAs) production were almost better in stage 1 than that in stage 2. Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS) confirmed the biodegradation of Reactive Black 5 (RB5) and Remazol Brilliant Blue R (RBBR) in hydrolysis acidification process. Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR DGGE) analyses revealed that significant difference of microbial community structures existed in stage 1 and 2. The dominant species in stage 1 was related to Bacteroidetes group, while the dominant species in stage 2 was related to Bacteroidetes and Firmicutes groups. From the results, it could be speculated that different dyes' structures might have significant influence on the existence and function of different bacterial species, which might supply information for bacteria screening and acclimation in the treatment of actual dyeing wastewater. PMID- 27714656 TI - Effects of four different phosphorus-locking materials on sediment and water quality in Xi'an moat. AB - To lower phosphorus concentration in Xi'an moat, four different phosphorus locking materials, namely, calcium nitrate, sponge-iron, fly ash, and silica alumina clay, were selected in this experiment to study their effects on water quality and sediment. Results of the continuous 68-day experiment showed that calcium nitrate was the most effective for controlling phosphorus concentration in overlying and interstitial water, where the efficiency of locking phosphorus was >97 and 90 %, respectively. Meanwhile, the addition of calcium nitrate caused Fe/Al-bound phosphorus (Fe/Al-P) content in sediment declining but Ca-bound phosphorus (Ca-P) and organic phosphorus (OP) content ascending. The phosphorus locking efficiency of sponge-iron in overlying and interstitial water was >72 and 66 %, respectively. Meanwhile, the total phosphorus (TP), OP, Fe/Al-P, and Ca-P content in sediment increased by 33.8, 7.7, 23.1, and 23.1 %, respectively, implying that under the action of sponge-iron, the locked phosphorus in sediment was mainly inorganic form and the phosphorus-locking efficiency of sponge-iron could be stable and persistent. In addition, the phosphorus-locking efficiency of fly ash was transient and limited, let alone silica alumina clay had almost no capacity for phosphorus-locking efficiency. Therefore, calcium nitrate and sponge iron were excellent phosphorus-locking agents to repair the seriously polluted water derived from an internal source. PMID- 27714657 TI - Accumulation of petroleum hydrocarbons in intracellular lipid bodies of the freshwater diatom Synedra acus subsp. radians. AB - The accumulation of hydrophobic compounds by phytoplankton plays a crucial role in the biogeochemical cycle of persistent organic pollutants (POPs) in aquatic environments. We studied the accumulation of polycyclic aromatic hydrocarbons (PAHs) in the freshwater diatom Synedra acus subsp. radians during its cultivation with crude oil hydrocarbons, using epifluorescent and laser confocal microscopy as well as gas chromatography-mass spectrometry (GC/MS) analysis. Our results revealed that in the presence of crude oil or an extract of a crude oil/n hexane solution (light oil), S. acus subsp. radians accumulated PAHs in its lipid bodies. During cultivation in the presence of a crude oil/n-hexane solution, the cells selectively accumulated C12-C18 alkanes, with a preference for C15 and C16 homologues. The length of n-alkane hydrocarbon chains accumulated in cells was similar to the acyl chains of fatty acids of the diatom. We therefore suggest that the insertion of n-alkanes into the membrane lipid bilayer promotes the transmembrane transport of PAH in diatoms. Our results confirm the hypothesis that diatoms play a role in the elimination of hydrophobic hydrocarbons from aquatic systems. PMID- 27714659 TI - Exposure to bisphenol A is directly associated with inflammation in healthy Korean adults. AB - It was recently discovered that bisphenol A (BPA) and phthalates are cardiovascular disruptors. Inflammation is central to the initiation and progression of cardiovascular disease (CVD). This study evaluated whether BPA and different phthalate metabolites are associated with the inflammation marker high sensitivity C-reactive protein (hs-CRP) in healthy Korean adults. This research is part of an ongoing, population-based study of Korean adults (30-64 years of age) conducted at the Cardiovascular and Metabolic Diseases Etiology Research Center (CMERC). The study enrolled 200 healthy volunteers (96 men, 104 women). Plasma hs-CRP was measured as an inflammation marker. BPA and five phthalate metabolites in urine were analyzed by using liquid chromatography/tandem mass spectrometry. BPA and monobenzyl phthalate (MBzP) differed significantly between the low-hs-CRP (<2 mg/L) and high-hs-CRP (>=2 mg/L) groups. BPA and MBzP were related to hs-CRP in an inverted L-shaped manner. High BPA levels (>=75th percentile) had significant odd ratios (ORs) for high hs-CRP even after adjusting for confounding factors related to obesity and insulin resistance, such as visceral fat volume, body mass index (BMI), adiponectin, high-density lipoprotein (HDL) cholesterol, hemoglobin A1c (HbA1c), and homeostasis model assessment of insulin resistance (HOMA-IR) (OR = 2.85; 95 % CI, 1.16-6.97). However, there was no significant association for MBzP >=75th percentile. BPA was significantly related to high hs-CRP, even after adjusting for factors related to obesity and insulin resistance. Therefore, BPA could have a direct relationship with systemic inflammation regardless of obesity or insulin resistance. PMID- 27714661 TI - The role of visible light active TiO2 specimens on the solar photocatalytic disinfection of E. coli. AB - Solar photocatalytic disinfection efficiency of novel visible light activated (VLA) photocatalysts was evaluated with the aim of assessing inactivation of Escherichia coli as the pathogen indicator organism present in drinking water. Influence of humic acid (HA) on the photocatalytic disinfection efficiency of the specified VLA TiO2 specimens i.e., N-doped, Se-doped, and Se-N co-doped TiO2 was also investigated. Photocatalytic disinfection efficiency was assessed by the enumeration of bacteria following selected irradiation periods. Degradation and compositional changes in organic matter (OM) was also tracked by means of UV-vis and advanced fluorescence spectroscopic (EEM features) parameters. Photocatalytic mineralization of the organic matter was followed by dissolved organic carbon contents. Presence of HA as a model organic compound of natural organic matter (NOM) displayed a retardation effect on solar photocatalytic abatement of E. coli. However, no distinctly different effect was observed under solar photolytic conditions due to the presence of HA. Regrowth of E. coli could not be assessed under the specified experimental conditions. A comparison was introduced with respect to the use of undoped TiO2 P-25 as the photocatalyst. PMID- 27714662 TI - Personality and uveitis. AB - BACKGROUND: Psycho-immunology is an emerging branch of science which studies the interaction between the brain and the immune system. The purpose of this study is to identify the types of personality factors in patients with non-infectious uveitis and to find its association with a particular uveitic entity if any. This is a prospective, observational, case-control study of 186 patients with non infectious uveitis (group A) and controls from general ophthalmology outpatient department (group B). "Global 5/SLOAN" personality questionnaire was used which is based on the five-factor theory of personality which describes personality factors based on the presence or absence of five primary dimensions, viz extroversion, orderliness, emotional stability, accommodation, and intellectual curiosity. Personality factors of patients from groups A and B were compared. History of present illness, clinical diagnosis, details of systemic ailment, and demographic information were collected. RESULTS: Group A comprised HLA-B27 related uveitis (n = 30), uveitis due to sarcoidosis (n = 10), Vogt-Koyanagi Harada syndrome (n = 5), sclero-kerato-uveitis due to rheumatoid arthritis (n = 5), and idiopathic uveitis in rest. Forty-five patients with uveitis had associated systemic ailment. Uveitis patients (n = 56) showed positive personality trait: S (social), C (calm), O (organized), A (accommodative), and I (inquisitive). In contrast, the control group (group B) which mainly comprised patients with non-pathological refractive error and visually insignificant cataract showed more number of negative personality traits (n = 62): R (reserved), L (limbic), U (unstructured), E (egocentric), and N (non-curious). This difference between the uveitis and control group was found to be statistically significant (p <= 0.001). The difference was also statistically significant for O (p = 0.008), U (p = 0.004), and C (p = 0.022) with chi-square test. Calm personality was found to be significantly associated with HLA-B27 related uveitis (p = 0.002). N, S, and A traits were seen almost equal in numbers in both the groups. U trait was absent in group A, whereas I trait had negligible presence in group B. CONCLUSIONS: Our finding of an association between organized personality type and uveitis and calm personality and HLA-B27-related uveitis warrants further studies to understand the complex mechanism of psycho-immunology in uveitis.

AB - Growing concern has been raised over the potential hazard of nanoparticles (NPs) on human health from ambient particulate air pollution. Silicon dioxide (SiO2) NPs are one of the most widely used nanoparticles in many sectors of industry. Research on NPs has focused mainly on their toxicity in organs. Meanwhile, NPs are present in the air year-round, but are more serious in winter. Thus, the aim of this study was to evaluate the inflammatory response to SiO2 NPs using in vivo test systems. The composition of particulate matter is complicated; however, elemental silicon accounts for a significant proportion. Cold exposure can induce many kinds of systemic reactions. Thus, the second aim of this study was also to evaluate the combined effect of NPs and cold exposure on human health. There is little research on the combined effects of nanoparticles and cold on inflammation. Sprague-Dawley rats were randomly divided into four groups: those exposed to SiO2 NPs by intratracheal instillation, those exposed to at 4 degrees C 4 h/day for 4 weeks, a combined SiO2 NPs and cold exposure group, and a control group. Inflammatory cell infiltration in the lungs was mainly observed after exposure to SiO2 NPs or cold. Hematoxylin and eosin staining revealed that inflammation of the lungs was more serious in the combined group. In the white adipose tissue and brown adipose tissue of the combined groups, the mRNA expressions of pro-inflammatory cytokines were upregulated. In conclusion, SiO2 NPs combined with cold exposure induced a stronger systemic inflammatory response, accompanied by more serious health hazards.

PMID- 27714658 TI - A systematic review on the adverse health effects of di-2-ethylhexyl phthalate. AB - Di (ethylhexyl) phthalate (DEHP) is a global environmental pollutant. This study aims to systematically review the literature on health effects of exposure to DEHP including effects on reproductive health, carcinogenesis, pregnancy outcome, and respiratory system. The literature search was done through Scopus, ISI Web of Science, Google Scholar, PubMed, Medline, and the reference lists of previous review articles to identify relevant articles published to June 2016 in each subject area. The inclusion criteria were as follows: original research, cross sectional studies, case-control studies, cohort studies, interventional studies, and review articles. Both human and animal studies were included. The search was limited to English language papers. Conference papers, editorials, and letters were not included. The systematic review was conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Overall, 152 of the 407 papers met the inclusion criteria. We provided an up-to-date comprehensive and critical assessment of both human and animal studies undertaken to explore the effects of DEHP. It revealed that in experimental studies, exposure to DEHP mainly targeted the reproductive, neurodevelopment, and respiratory systems. Human studies reported that exposure to this contaminant had carcinogenic effects and influenced neurodevelopment in early life. This systematic review underscored the adverse health effects of DEHP for pregnant women and the pediatric age group. It summarizes different response of humans and experimental animals to DEHP exposure, and some suggested underlying mechanisms. PMID- 27714665 TI - Picture-word interference is a Stroop effect: A theoretical analysis and new empirical findings. AB - The picture-word interference (PWI) paradigm and the Stroop color-word interference task are often assumed to reflect the same underlying processes. On the basis of a PRP study, Dell'Acqua et al. (Psychonomic Bulletin & Review, 14: 717-722, 2007) argued that this assumption is incorrect. In this article, we first discuss the definitions of Stroop- and picture-word interference. Next, we argue that both effects consist of at least four components that correspond to four characteristics of the distractor word: (1) response-set membership, (2) task relevance, (3) semantic relatedness, and (4) lexicality. On the basis of this theoretical analysis, we conclude that the typical Stroop effect and the typical PWI effect mainly differ in the relative contributions of these four components. Finally, the results of an interference task are reported in which only the nature of the target - color or picture - was manipulated and all other distractor task characteristics were kept constant. The results showed no difference between color and picture targets with respect to all behavioral measures examined. We conclude that the assumption that the same processes underlie verbal interference in color and picture naming is warranted. PMID- 27714666 TI - Sex differences in virtual navigation influenced by scale and navigation experience. AB - The Morris water maze is a spatial abilities test adapted from the animal spatial cognition literature and has been studied in the context of sex differences in humans. This is because its standard design, which manipulates proximal (close) and distal (far) cues, applies to human navigation. However, virtual Morris water mazes test navigation skills on a scale that is vastly smaller than natural human navigation. Many researchers have argued that navigating in large and small scales is fundamentally different, and small-scale navigation might not simulate natural human navigation. Other work has suggested that navigation experience could influence spatial skills. To address the question of how individual differences influence navigational abilities in differently scaled environments, we employed both a large- (146.4 m in diameter) and a traditional- (36.6 m in diameter) scaled virtual Morris water maze along with a novel measure of navigation experience (lifetime mobility). We found sex differences on the small maze in the distal cue condition only, but in both cue-conditions on the large maze. Also, individual differences in navigation experience modulated navigation performance on the virtual water maze, showing that higher mobility was related to better performance with proximal cues for only females on the small maze, but for both males and females on the large maze.

PMID- 27714667 TI - Challenges in the management of patients with maple syrup urine disease diagnosed by newborn screening in a developing country. AB - Maple syrup urine disease (MSUD) is a rare inborn error of metabolism resulting from a deficiency in the branched-chain alpha-ketoacid dehydrogenase complex. MSUD has been reported to be the most common inborn error of metabolism in the Philippines. We described all patients with maple syrup urine disease patients diagnosed through newborn screening during its first 2 years of implementation and the challenges encountered during their medical management. There were 24 patients diagnosed with maple syrup urine disease for the 2-year period. All patients needed hospital admission. The most common complication during hospital admission was infection, needing intravenous antibiotics which were given to 21 of the patients. Out of the 24 diagnosed, 16 patients are alive, while eight have died. Several neurologic and non-neurologic complications have been observed during the follow-up of the patients. The common challenges of MSUD management in a low-resource setting identified in this study were late diagnosis, lack of access to metabolic specialists and medical supplies, nosocomial septicemia, and protein deficiency. Aside from early properly timed collection, improvement in other logistical concerns will also help in earlier diagnosis. Mechanisms of transfer of critically ill patients must be improved. Hospitals in difficult-to reach areas must be equipped to handle critical metabolic cases when transfers are not possible. Newborn screening has been proven to improve outcome in patients with MSUD but the success of the program in preventing disability is also dependent on improvements in other aspects of healthcare. PMID- 27714670 TI - Mechanisms, Imaging, and Therapy in Stroke Recovery. PMID- 27714672 TI - miR-203 is a predictive biomarker for colorectal cancer and its expression is associated with BIRC5. AB - The purpose of this study was to explore the role of miR-203 in colorectal cancer (CRC) and evaluate the correlation between miR-203 and BIRC5. The expressions of miR-203 in the tissues of 122 CRC patients (with non-tumor tissues as controls) and those from 30 healthy donors were detected by TaqMan(r) MicroRNA assay. BIRC5s expressions in CRC and non-tumor tissues were detected by immunohistochemistry. Significantly less miR-203 was expressed in CRC tissues (P < 0.05) than in non-tumor tissues. Furthermore, low expression level of miR-203 was correlated with distant metastasis (DM), lymph node metastasis (LNM), and TNM stage (P < 0.05), but there were no significant differences between tumor size or gender. The positive expression rates of BIRC5 in CRC and non-tumor tissues were 73.77 % (90/122) and 30.32 % (37/122), respectively. The expression intensity of BIRC5 in CRC was significantly higher than that of non-tumor tissues (P < 0.05). It was significantly correlated with DM, LNM, and TNM stage (P < 0.05). Finally, miR-203 expression was negatively associated with that of BIRC5 (r = -0.8150, P < 0.05). In conclusion, miR-203 was down-regulated in CRC tissues and involved in the onset and progression of CRC. The expressions of miR-203 and BIRC5 in CRC were significantly negatively correlated, suggesting that BIRC5 may be regulated by miR-203. miR-203 is a potential suppressor and predictive biomarker for CRC. PMID- 27714669 TI - A Post-stroke Therapeutic Regimen with Omega-3 Polyunsaturated Fatty Acids that Promotes White Matter Integrity and Beneficial Microglial Responses after Cerebral Ischemia. AB - White matter injury induced by ischemic stroke elicits sensorimotor impairments, which can be further deteriorated by persistent proinflammatory responses. We previously reported that delayed and repeated treatments with omega-3 polyunsaturated fatty acids (n-3 PUFAs) improve spatial cognitive functions and hippocampal integrity after ischemic stroke. In the present study, we report a post-stroke n-3 PUFA therapeutic regimen that not only confers protection against neuronal loss in the gray matter but also promotes white matter integrity. Beginning 2 h after 60 min of middle cerebral artery occlusion (MCAO), mice were randomly assigned to receive intraperitoneal docosahexaenoic acid (DHA) injections (10 mg/kg, daily for 14 days), alone or in combination with dietary fish oil (FO) supplements starting 5 days after MCAO. Sensorimotor functions, gray and white matter injury, and microglial responses were examined up to 28 days after MCAO. Our results showed that DHA and FO combined treatment facilitated long-term sensorimotor recovery and demonstrated greater beneficial effect than DHA injections alone. Mechanistically, n-3 PUFAs not only offered direct protection on white matter components, such as oligodendrocytes, but also potentiated microglial M2 polarization, which may be important for white matter repair. Notably, the improved white matter integrity and increased M2 microglia were strongly linked to the mitigation of sensorimotor deficits after stroke upon n-3 PUFA treatments. Together, our results suggest that post-stroke DHA injections in combination with FO dietary supplement benefit white matter restoration and microglial responses, thereby dictating long-term functional improvements. PMID- 27714671 TI - BRCA1 and MDM2 as independent blood-based biomarkers of head and neck cancer. AB - We investigated the role of BRCA1, MDM2, and p53 in the pathogenesis of head and neck cancer (HNC) and evaluated their potential utility as blood-based predictive biomarkers of HNC. Immunostaining of tissue biopsies and whole blood lymphocytes (WBL) of 36 HNC patients were evaluated by immunohistochemistry (IHC) and immunocytochemistry (ICC), respectively. The staining intensities of BRCA1 and MDM2 in matched tissue and blood samples were significantly associated with cancer stage. Furthermore, the cellular levels of BRCA1, MDM2, and p53 were evaluated in peripheral blood lymphocytes (PBL) of 134 HNC patients and 126 controls by slot blotting. Expression levels of all three proteins in PBL of HNC patients varied significantly with respect to those of controls (p < 0.0001) with BRCA1 downregulated to 75 % of control and MDM2 and p53 upregulated to 1.7- and 1.4-fold the control level, respectively. Moreover, positive correlation was observed between expression levels of BRCA1, MDM2, and p53 in matched tissue biopsies-WBL (r s = 0.840, 0.754, and 0.806, respectively), tissue biopsies-PBL (r s = 0.745, 0.736, and 0.776, respectively), and PBL-WBL (r s = 0.709, 0.758, and 0.740, respectively), validating the hypothesis that these proteins may serve as blood-based biomarkers of HNC. Bias-corrected and accelerated (BCa) bootstrap cross-validation estimation of receiver operating characteristics (ROC) analysis established BRCA1 (AUC = 0.726, sensitivity = 89 %, NPV = 82 %) and MDM2 (AUC = 0.827, sensitivity = 85 %, NPV = 81 %) as predictive biomarkers for HNC. In conclusion, this study suggests that BRCA1 and MDM2 play a crucial role in the pathogenesis of HNC and could be used independently as predictive biomarkers for HNC. PMID- 27714673 TI - Regulation of exosomes released from normal ovarian epithelial cells and ovarian cancer cells. AB - As important cell to cell communicator, exosomes carry a range of bioactive molecules which can significantly influence phenotype of recipient cells. Inhibiting or removing cancer cell-derived exosomes are of therapeutic interest. However, regulation of secretion and release mechanism of exosomes is still unclear. To explore the regulation of exosomes released from normal ovarian epithelial cells and ovarian cancer cells, a normal ovarian epithelial cell line and three ovarian epithelial cancer cell lines were utilized to investigate their exosomes' release and regulation. A cervical cancer cell SiHa was used for identifying tissue specificity. NanoSight NS500 was used to quantify exosome numbers. Exosomes were labeled and observed by confocal microscopy to investigate their interaction with different ovarian cell lines. Exosomes released from normal or ovarian cancer cells were regulated by the extracellular exosomes. Exosome release was inhibited with the extracellular exosome concentration increase. Exosomes from normal ovarian cell and cervical cancer cell also inhibited ovarian cancer cell-derived exosome release, and there was no tissue specificity. PKH26-labeled exosomes from normal ovarian cell and cervical cancer cell were uptaken by ovarian cancer cells. Release of exosomes from ovarian cancer cell is regulated by a feedback mechanism without tissue specificity. This may provide a therapeutic approach to control the release of exosomes from ovarian cancer cells. PMID- 27714674 TI - Highly expressed lncRNA CRNDE promotes cell proliferation through Wnt/beta catenin signaling in renal cell carcinoma. AB - Recently, numerous studies revealed that long non-coding RNAs (lncRNAs) play complex roles in the field of tumor biology, while the functions of lncRNA in renal cell carcinoma (RCC) remain largely unknown. In the current study, we retrieved Oncomine database and found a lncRNA colorectal neoplasia differentially expressed (CRNDE) which is highly expressed in different cohorts of RCC patients; this clue reminds us that CRNDE might exert its functions in RCC tumorigenesis. We then detected the level of CRNDE in fresh RCC tissues and found that CRNDE is significantly up-regulated compared with adjacent tissues. Furthermore, both loss and gain function assays revealed that CRNDE promotes RCC cell proliferation and growth both in vitro and in vivo.In addition, we found that CRNDE regulates the cell cycle transition from G0/G1 stage to S stage and modulates the expression of CCND1 and CCNE1. Moreover, we further illustrated that CRNDE activates Wnt/beta-catenin signaling in RCC cell lines. Taken together, in the current study, we found that lncRNA CRNDE is highly expressed in RCC malignant tissues and the heightened CRNDE robustly promotes RCC cell proliferation through activating Wnt/beta-catenin signaling; our findings enlarge our knowledge in the molecular pathology of RCC tumorigenesis.

AB - INTRODUCTION: The benefits of rotavirus (RV) vaccination in developed countries have focused on reductions in mortality, hospitalization and medical visits, and herd protection. We investigated other aspects related to RV-induced nosocomial infection, duration of hospital stay, age shift, and sustained vaccine impact (VI) over time. METHOD: RotaBIS (Rotavirus Belgian Impact Study; ClinicalTrials.gov identifier, NCT01563146) annually collects retrospective data on hospitalization linked to RV testing in children up to 5 years old from 11 pediatric wards located all over Belgium. Data from 2005 to 2012 have been split in pre- (2005-2006) and post-vaccination (2007-2012) period. Information was collected on age, gender, RV test result, nosocomial infection caused by RV and duration of hospital stay. RESULTS: Over the 6-year period after the introduction of the RV vaccine, an 85% reduction in nosocomial infections was observed (221 in 2005 to 33 in 2012, p < 0.001). A significant reduction of almost 2 days in average duration of hospital stay per event was observed overall (7.62 days in 2005 to 5.77 days in 2012, p < 0.001). The difference is mainly explained by the higher reduction in number of nosocomial infections. A pronounced age shift (+24%, p < 0.01) of RV nosocomial infection to infants <=2 months old was observed, increasing with length of post-vaccination period. VI was maintained over the follow-up (+/-79% VI per birth cohort). A decrease was seen depending on age, 85% (95% CI 76-91%) in the youngest to 63% (95% CI 22-92%) in the oldest age group. CONCLUSION: The higher reduction in nosocomial infection may affect the overall average duration of hospital stay for RV infection. No change in VI by birth cohort, but a reduction by age group was observed. These findings could be important for decision-makers considering the introduction of universal mass RV vaccination programs. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT01563146. FUNDING: GlaxoSmithKline Biologicals SA (Rixensart, Belgium). PMID- 27714679 TI - Survey of electric bidet toilet use among community dwelling Japanese people and correlates for an itch on the anus. AB - OBJECTIVES: We conducted a survey to investigate the use of bidet toilets among community dwelling Japanese people and explored the correlates for an itch on the anus. METHODS: A questionnaire-based survey was conducted among a convenience sample of individuals, who were derived from outpatients and employees of Kameda Medical Center, and students and employees of two technical colleges. RESULTS: A total of 4,963 respondents were evaluated in this study, 55 % of whom used bidet toilets either before or after defecation, and at least 30 % of bidet users washed the anus before defecation, partly to aid defecation. Men rather than women, and older people (aged >=50 years) rather than younger people used bidets more actively. Logistic regression analysis showed that the correlates for an itch on the anus included male sex, younger age, washing the anus before defecation, warmer water for washing the anus after defecation, and the frequency of fecal leakage. CONCLUSIONS: Nearly, one-third of bidet toilet users washed the anus before defecation. An itch on the anus may be associated with the active use of bidets. PMID- 27714675 TI - The roles of microRNAs related with progression and metastasis in human cancers. AB - Metastasis is an important factor in predicting the prognosis of the patients with cancers and contributes to high cancer-related mortality. Recent studies indicated that microRNAs (miRNAs) played a functional role in the initiation and progression of human malignancies. MicroRNAs are small non-coding RNAs of about 22 nucleotides in length that can induce messenger RNA (mRNA) degradation or repress mRNA translation by binding to the 3' untranslated region (3'-UTR) of their target genes. Overwhelming reports indicated that miRNAs could regulate cancer invasion and metastasis via epithelial-to-mesenchymal transition (EMT) related and/or non-EMT-related mechanisms. In this review, we concentrate on the underlying mechanisms of miRNAs in regulating cancer progression and metastasis. PMID- 27714678 TI - Roles of defective ALDH2 polymorphism on liver protection and cancer development. AB - Because serum transaminases elevate alcohol dose dependently as a consequence of liver injury, they serve as useful biological markers of excessive drinking. However, these markers are inadequate in individuals with a defective allele of the aldehyde dehydrogenase 2 gene, ALDH2*2, because they show a different correlation with the amount of ethanol. For example, the serum alanine aminotransferase (ALT) level could become even lower than the baseline after alcohol intake in ALDH2*2 carriers. In fact, multiple studies suggest that ALDH2*2 is a hepato-protective factor in healthy individuals. Importantly, excessive drinking is particularly dangerous in carriers of ALDH2*2 because the risk of alcohol-related cancer is much higher than that for ALDH2*1/*1 carriers. Without recognizing the genotype interaction on serum transaminase, the opportunity to warn people about potential cancer risks is missed owing to incorrect interpretation. This is particularly important in East Asian countries where approximately half of the population carries the ALDH2*2 allele. To date, the mechanism of liver protection from ethanol load in individuals with ALDH2*2 has not been fully elucidated. However, some reasonable mechanisms have been suggested by experimental studies, including remodelling of detoxifying systems. Further studies to uncover the whole mechanism are anticipated. PMID- 27714680 TI - Live donor liver transplantation for alcoholic hepatitis. AB - Liver transplantation is a definitive therapy for patients with end-stage liver disease and cirrhosis, with improvement in survival and quality of life. Patients are carefully screened and selected for this modality of treatment to achieve maximum survival benefit. For example, a patient with hepatocellular carcinoma is a candidate if he or she is within Milan criteria and has no significant comorbidity. Similarly, patients with alcoholic cirrhosis are transplant candidates if they are deemed to have been rehabilitated from abusive alcohol consumption and are at low risk for recidivism. More recently, carefully selected patients with alcoholic hepatitis have been successfully transplanted. The preferred transplantation modality is cadaveric liver transplantation. However, living donor liver transplantation is carried out if there is no cadaveric liver organ allocation system, or if the patient is deemed to be at low priority for cadaveric organ transplantation based on the allocation system. Living donor liver transplantation for alcoholic hepatitis needs to be addressed with this background in mind. PMID- 27714682 TI - Glial Cells and Integrity of the Nervous System. AB - Today, there is enormous progress in understanding the function of glial cells, including astroglia, oligodendroglia, Schwann cells, and microglia. Around 150 years ago, glia were viewed as a glue among neurons. During the course of the twentieth century, microglia were discovered and neuroscientists' views evolved toward considering glia only as auxiliary cells of neurons. However, over the last two to three decades, glial cells' importance has been reconsidered because of the evidence on their involvement in defining central nervous system architecture, brain metabolism, the survival of neurons, development and modulation of synaptic transmission, propagation of nerve impulses, and many other physiological functions. Furthermore, increasing evidence shows that glia are involved in the mechanisms of a broad spectrum of pathologies of the nervous system, including some psychiatric diseases, epilepsy, and neurodegenerative diseases to mention a few. It appears safe to say that no neurological disease can be understood without considering neuron-glia crosstalk. Thus, this book aims to show different roles played by glia in the healthy and diseased nervous system, highlighting some of their properties while considering that the various glial cell types are essential components not only for cell function and integration among neurons, but also for the emergence of important brain homeostasis. PMID- 27714683 TI - NG2-glia, More Than Progenitor Cells. AB - NG2-glia are a mysterious and ubiquitous glial population with a highly branched morphology. Initial studies suggested that their unique function is the generation and maintenance of oligodendrocytes in the central nervous system (CNS), important for proper myelination and therefore for axonal support and fast conduction velocity. Over the last years this simplistic notion has been dramatically changed: the wide and homogeneous distribution of NG2-glia within all areas of the developing CNS that is maintained during the whole lifespan, their potential to also differentiate into other cell types in a spatiotemporal manner, their active capability of maintaining their population and their dynamic behavior in altered conditions have raised the question: are NG2-glia simple progenitor cells or do they play further major roles in the normal function of the CNS? In this chapter, we will discuss some important features of NG2-glia like their homeostatic distribution in the CNS and their potential to differentiate into diverse cell types. Additionally, we will give some further insights into the properties that these cells have, like the ability to form synapses with neurons and their plastic behavior triggered by neuronal activity, suggesting that they may play a role specifically in myelin and more generally in brain plasticity. Finally, we will briefly review their behavior in disease models suggesting that their function is extended to repair the brain after insult. PMID- 27714684 TI - Pharmacological Tools to Study the Role of Astrocytes in Neural Network Functions. AB - Despite that astrocytes and microglia do not communicate by electrical impulses, they can efficiently communicate among them, with each other and with neurons, to participate in complex neural functions requiring broad cell-communication and long-lasting regulation of brain function. Glial cells express many receptors in common with neurons; secrete gliotransmitters as well as neurotrophic and neuroinflammatory factors, which allow them to modulate synaptic transmission and neural excitability. All these properties allow glial cells to influence the activity of neuronal networks. Thus, the incorporation of glial cell function into the understanding of nervous system dynamics will provide a more accurate view of brain function. Our current knowledge of glial cell biology is providing us with experimental tools to explore their participation in neural network modulation. In this chapter, we review some of the classical, as well as some recent, pharmacological tools developed for the study of astrocyte's influence in neural function. We also provide some examples of the use of these pharmacological agents to understand the role of astrocytes in neural network function and dysfunction. PMID- 27714685 TI - Microglia Function in the Normal Brain. AB - The activation of microglia has been recognized for over a century by their morphological changes. Long slender microglia acquire a short sturdy ramified shape when activated. During the past 20 years, microglia have been accepted as an essential cellular component for understanding the pathogenic mechanism of many brain diseases, including neurodegenerative diseases. More recently, functional studies and imaging in mouse models indicate that microglia are active in the healthy central nervous system. It has become evident that microglia release several signal molecules that play key roles in the crosstalk among brain cells, i.e., astrocytes and oligodendrocytes with neurons, as well as with regulatory immune cells. Recent studies also reveal the heterogeneous nature of microglia diverse functions depending on development, previous exposure to stimulation events, brain region of residence, or pathological state. Subjects to approach by future research are still the unresolved questions regarding the conditions and mechanisms that render microglia protective, capable of preventing or reducing damage, or deleterious, capable of inducing or facilitating the progression of neuropathological diseases. This novel knowledge will certainly change our view on microglia as therapeutic target, shifting our goal from their general silencing to the generation of treatments able to change their activation pattern. PMID- 27714686 TI - Physiological Functions of Glial Cell Hemichannels. AB - The brain performs exceptionally complex and dynamic tasks that depend on the coordinated interaction of neurons, glial cells, endothelial cells, pericytes, smooth muscle cells, ependymal cells, and circulating blood cells. Among these cells, glial cells have emerged as crucial protagonists in the regulation of synaptic transmission and neural function. Indeed, these cells express a wide range of receptors that enable them to sense changes in neuronal activity and the microenvironment by responding locally via the release of bioactive molecules known as gliotransmitters. In the central nervous system (CNS), a novel mechanism that allows gliotransmission via the opening of hemichannels has been proposed. These channels are composed of six protein subunits consisting of connexins or pannexins, which are two highly conserved protein families that are encoded by 21 and 3 genes, respectively, in humans. Typically, glial cell hemichannels exhibit low levels of activity, but this activity is sufficient to ensure the release of a broad spectrum of gliotransmitters, including ATP, D-serine, glutamate, adenosine, and glutathione. Here, we briefly review the current findings regarding the effects of the hemichannel-dependent release of gliotransmitters on the physiology of the CNS. PMID- 27714687 TI - Role of Astrocytes in Central Respiratory Chemoreception. AB - Astrocytes perform various homeostatic functions in the nervous system beyond that of a supportive or metabolic role for neurons. A growing body of evidence indicates that astrocytes are crucial for central respiratory chemoreception. This review presents a classical overview of respiratory central chemoreception and the new evidence for astrocytes as brainstem sensors in the respiratory response to hypercapnia. We review properties of astrocytes for chemosensory function and for modulation of the respiratory network. We propose that astrocytes not only mediate between CO2/H+ levels and motor responses, but they also allow for two emergent functions: (1) Amplifying the responses of intrinsic chemosensitive neurons through feedforward signaling via gliotransmitters and; (2) Recruiting non-intrinsically chemosensitive cells thanks to volume spreading of signals (calcium waves and gliotransmitters) to regions distant from the CO2/H+ sensitive domains. Thus, astrocytes may both increase the intensity of the neuron responses at the chemosensitive sites and recruit of a greater number of respiratory neurons to participate in the response to hypercapnia. PMID- 27714681 TI - Asian-Pacific Association for the Study of the Liver (APASL) consensus guidelines on invasive and non-invasive assessment of hepatic fibrosis: a 2016 update. AB - Hepatic fibrosis is a common pathway leading to liver cirrhosis, which is the end result of any injury to the liver. Accurate assessment of the degree of fibrosis is important clinically, especially when treatments aimed at reversing fibrosis are being evolved. Despite the fact that liver biopsy (LB) has been considered the "gold standard" of assessment of hepatic fibrosis, LB is not favored by patients or physicians owing to its invasiveness, limitations, sampling errors, etc. Therefore, many alternative approaches to assess liver fibrosis are gaining more popularity and have assumed great importance, and many data on such approaches are being generated. The Asian Pacific Association for the Study of the Liver (APASL) set up a working party on liver fibrosis in 2007, with a mandate to develop consensus guidelines on various aspects of liver fibrosis relevant to disease patterns and clinical practice in the Asia-Pacific region. The first consensus guidelines of the APASL recommendations on hepatic fibrosis were published in 2009. Due to advances in the field, we present herein the APASL 2016 updated version on invasive and non-invasive assessment of hepatic fibrosis. The process for the development of these consensus guidelines involved review of all available published literature by a core group of experts who subsequently proposed consensus statements followed by discussion of the contentious issues and unanimous approval of the consensus statements. The Oxford System of the evidence-based approach was adopted for developing the consensus statements using the level of evidence from one (highest) to five (lowest) and grade of recommendation from A (strongest) to D (weakest). The topics covered in the guidelines include invasive methods (LB and hepatic venous pressure gradient measurements), blood tests, conventional radiological methods, elastography techniques and cost-effectiveness of hepatic fibrosis assessment methods, in addition to fibrosis assessment in special and rare situations. PMID- 27714688 TI - Purine Signaling and Microglial Wrapping. AB - Microglial cells are highly dynamic cells with processes continuously moving to survey the surrounding territory. Microglia possess a broad variety of surface receptors and subtle changes in their microenvironment cause microglial cell processes to extend, retract, and interact with neuronal synaptic contacts. When the nervous system is disturbed, microglia activate, proliferate, and migrate to sites of injury in response to alert signals. Released nucleotides like ATP and UTP are among the wide range of molecules promoting microglial activation and guiding their migration and phagocytic function. The increased concentration of nucleotides in the extracellular space could be involved in the microglial wrapping found around injured neurons in various pathological conditions, especially after peripheral axotomy. Microglial wrappings isolate injured neurons from synaptic inputs and facilitate the molecular dialog between endangered or injured neurons and activated microglia. Astrocytes may also participate in neuronal ensheathment. Degradation of ATP by microglial ecto-nucleotidases and the expression of various purine receptors might be decisive in regulating the function of enwrapping glial cells and in determining the fate of damaged neurons, which may die or may regenerate their axons and survive. PMID- 27714689 TI - Oligodendrocytes: Functioning in a Delicate Balance Between High Metabolic Requirements and Oxidative Damage. AB - The study of the metabolic interactions between myelinating glia and the axons they ensheath has blossomed into an area of research much akin to the elucidation of the role of astrocytes in tripartite synapses (Tsacopoulos and Magistretti in J Neurosci 16:877-885, 1996). Still, unlike astrocytes, rich in cytochrome-P450 and other anti-oxidative defense mechanisms (Minn et al. in Brain Res Brain Res Rev 16:65-82, 1991; Wilson in Can J Physiol Pharmacol. 75:1149-1163, 1997), oligodendrocytes can be easily damaged and are particularly sensitive to both hypoxia and oxidative stress, especially during their terminal differentiation phase and while generating myelin sheaths. In the present review, we will focus in the metabolic complexity of oligodendrocytes, particularly during the processes of differentiation and myelin deposition, and with a specific emphasis in the context of oxidative stress and the intricacies of the iron metabolism of the most iron-loaded cells of the central nervous system (CNS). PMID- 27714690 TI - Schwann Cell and Axon: An Interlaced Unit-From Action Potential to Phenotype Expression. AB - Here we propose a model of a peripheral axon with a great deal of autonomy from its cell body-the autonomous axon-but with a substantial dependence on its ensheathing Schwann cell (SC), the axon-SC unit. We review evidence in several fields and show that (i) axons can extend sprouts and grow without the concurrence of the cell body, but regulated by SCs; (ii) axons synthesize their proteins assisted by SCs that supply them with ribosomes and, probably, with mRNAs by way of exosomes; (iii) the molecular organization of the axoplasm, i.e., its phenotype, is regulated by the SC, as illustrated by the axonal microtubular content, which is down-regulated by the SC; and (iv) the axon has a program for self-destruction that is boosted by the SC. The main novelty of this model axon SC unit is that it breaks with the notion that all proteins of the nerve cell are specified by its own nucleus. The notion of a collaborative specification of the axoplasm by more than one nucleus, which we present here, opens a new dimension in the understanding of the nervous system in health and disease and is also a frame of reference to understand other tissues or cell associations. PMID- 27714691 TI - Age-Dependent Changes in the Activation and Regulation of Microglia. AB - As we age, a large number of physiological and molecular changes affect the normal functioning of cells, tissues, and the organism as a whole. One of the main changes is the establishment of a state of systemic inflammatory activation, which has been termed "inflamm-aging"; a mild chronic inflammation of the aging organism that reduces the ability to generate an efficient response against stressor stimuli. As any other system, the nervous system undergoes these aging related changes; the neuroinflammatory state depends mainly on the dysregulated activation of microglia, the innate immune cells of the central nervous system (CNS) and the principal producers of reactive oxygen species. As the brain ages, microglia acquire a phenotype that is increasingly inflammatory and cytotoxic, generating a hostile environment for neurons. There is mounting evidence that this process facilitates development of neurodegenerative diseases, for which the greatest risk factor is age. In this chapter, we will review key aging-associated changes occurring in the central nervous system, focusing primarily on the changes that occur in aging microglia, the inflammatory and oxidative stressful environment they establish, and their impaired regulation. In addition, we will discuss the effects of aged microglia on neuronal function and their participation in the development of neurodegenerative pathologies such as Parkinson's and Alzheimer's diseases. PMID- 27714692 TI - Astrocyte Dysfunction in Developmental Neurometabolic Diseases. AB - Astrocytes play crucial roles in maintaining brain homeostasis and in orchestrating neural development, all through tightly coordinated steps that cooperate to maintain the balance needed for normal development. Here, we review the alterations in astrocyte functions that contribute to a variety of developmental neurometabolic disorders and provide additional data on the predominant role of astrocyte dysfunction in the neurometabolic neurodegenerative disease glutaric acidemia type I. Finally, we describe some of the therapeutical approaches directed to neurometabolic diseases and discuss if astrocytes can be possible therapeutic targets for treating these disorders. PMID- 27714693 TI - Microglia in Cancer: For Good or for Bad? AB - Glioblastoma is a malignant tumor of astrocytic origin that is highly invasive, proliferative and angiogenic. Despite current advances in multimodal therapies, such as surgery, radio- and chemotherapy, the outcome for patients with glioblastoma is nearly always fatal. The glioblastoma microenvironment has a tremendous influence over the tumor growth and spread. Microglia and macrophages are abundant cells in the tumor mass. Increasing evidence indicates that glioblastoma recruits these cell populations and signals in a way that microglia and macrophages are subverted to promote tumor progression. In this chapter, we discuss some aspects of the interaction between microglia and glioblastoma, consequences of this interaction for tumor progression and the possibility of microglial cells being used as therapeutic vectors, which opens up new alternatives for the development of GBM therapies targeting microglia. PMID- 27714694 TI - Peripheral Inflammation and Demyelinating Diseases. AB - In recent decades, several neurodegenerative diseases have been shown to be exacerbated by systemic inflammatory processes. There is a wide range of literature that demonstrates a clear but complex relationship between the central nervous system (CNS) and the immunological system, both under naive or pathological conditions. In diseased brains, peripheral inflammation can transform "primed" microglia into an "active" state, which can trigger stronger pathological responses. Demyelinating diseases are a group of neurodegenerative diseases characterized by inflammatory lesions associated with demyelination, which in turn induces axonal damage, neurodegeneration, and progressive loss of function. Among them, the most important are multiple sclerosis (MS) and neuromyelitis optica (NMO). In this review, we will analyze the effect of specific peripheral inflammatory stimuli in the progression of demyelinating diseases and discuss their animal models. In most cases, peripheral immune stimuli are exacerbating. PMID- 27714695 TI - Regulation of Oligodendrocyte Differentiation and Myelination by Nuclear Receptors: Role in Neurodegenerative Disorders. AB - During development and through adulthood, differentiation of diverse cell types is controlled by specific genetic and molecular programs for which transcription factors are master regulators of gene expression. Here, we present an overview of the role of nuclear receptors and their selective pharmacological modulators in oligodendrocytes linage, their role in myelination and remyelination and their potential use as a therapeutic strategy for demyelinating diseases. We discuss several aspects of nuclear receptors including: (1) the biochemistry of nuclear receptors superfamily; (2) their role on stem cells physiology, focusing in differentiation and cell removal; (3) the role of nuclear receptor in the oligodendrocytes cell linage, from oligodendrocyte progenitors cells to mature myelinating cells; and (4) the therapeutics opportunities of nuclear receptors for specific demyelinating diseases. PMID- 27714696 TI - The Role of Galectin-3: From Oligodendroglial Differentiation and Myelination to Demyelination and Remyelination Processes in a Cuprizone-Induced Demyelination Model. AB - The aim of this work was to combine our previously published results with our new data to show how galectin-3 (Gal-3) controls myelin integrity and function, promotes oligodendroglial cell differentiation, and regulates microglial responses to limit cuprizone- (CPZ)-induced demyelination and foster remyelination. In this study, 8-week-old Gal-3-deficient (Lgals3 -/-) and wild type (WT) mice were fed a diet containing 0.2 % CPZ w/w for 6 weeks, after which CPZ was withdrawn in order to allow remyelination. Our results show that remyelination was less efficient in Lgals3 -/- than in WT mice. Electron microscopic images from remyelinated sections in Lgals3 -/- mice revealed collapsed axons with a defective myelin wrap, while remyelinated WT mice had normal axons without relevant myelin wrap disruption. MMP-3 expression increased during remyelination in WT but not in Lgals3 -/- mice. The number of CD45+, TNFalpha+ and TREM-2b+ cells decreased only in WT mice only, with no alterations in Lgals3 -/- mice during demyelination and remyelination. Therefore, Gal-3 influences remyelination by mechanisms involving the tuning of microglial cells, modulation of MMP activity, and changes in myelin architecture. PMID- 27714697 TI - Prenatal Systemic Hypoxia-Ischemia and Oligodendroglia Loss in Cerebellum. AB - Hypoxic-ischemic (HI) injury is an important cause of death and disabilities. Despite all improvements in neonatal care, the number of children who suffer some kind of injury during birth has remained stable in the last decade. A great number of studies have shown alterations in neural cells and many animal models have been proposed in the last 5 decades. Robinson et al. (2005) proposed an HI model in which the uterine arteries are temporarily clamped on the 18th gestation day. The findings were quite similar to the ones observed in postmortem studies. The white matter is clearly damaged, and a great amount of astrogliosis takes place both in the gray and white matters. Motor changes were also found but no data regarding the cerebellum, an important structure related to motor performance, was presented. Using this model, we have shown an increased level of iNOS at P0 and microgliosis and astrogliosis at P9, and astrogliosis at P23 (up to 4 weeks from the insult). NO is important in migration, maturation, and synaptic plasticity, but in exacerbated levels it may also contribute to cellular and tissue damage. We have also evaluated oligodendroglia development in the cerebellum. At P9 in HI animals, we found a decrease in the number of PDGFRalpha+ cells and an apparent delay in myelination, suggesting a failure in oligodendroglial progenitors migration/maturation and/or in the myelination process. These results point to an injury in cerebellar development that might help to explain the motor problems in HI. PMID- 27714698 TI - Acceptability of Mini-Tablets in Young Children: Results from Three Prospective Cross-over Studies. AB - To ensure optimal, reliable treatment, it is necessary to investigate the efficacy, safety and the optimal dose of drug substances and to develop suitable age-specific pharmaceutical formulations for the different paediatric age groups due to a lack of evidence-based therapeutic options for children. While WHO recommends the use of solid dosage forms in general, European Medicines Agency (EMA) requires evidence for the suitability of these dosage forms in the targeted age group. This review aims to summarize and discuss the data obtained in acceptability studies on the suitability of coated and uncoated mini-tablets in children of different ages in comparison to a sweet syrup considered as gold standard. The predefined outcome parameters 'acceptability' and 'capability to swallow' of the two different mini-tablet formulations (uncoated and film-coated) were statistically significantly higher than that of the syrup. PMID- 27714699 TI - Accelerated Stability Modeling for Peptides: a Case Study with Bacitracin. AB - The Accelerated Stability Assessment Program (ASAP) was applied for the first time to a peptide, the antibiotic active pharmaceutical ingredient bacitracin. Bacitracin and its complex with zinc were exposed to temperature and relative humidity conditions from 50 to 80 degrees C and from 0 to 63% for up to 21 days. High-performance liquid chromatography was used to analyze the stressed samples for both degradant formation and loss of the active (bacitracin A) and two inactive isoforms, with identities confirmed by mass spectrometry. These data were then analyzed using a humidity-corrected Arrhenius equation and isoconversion approach to create a shelf-life predicting model for typical storage conditions. Model fitting was found to be good with low residuals in both temperature and relative humidity axes for all parameters examined. The generated model's predictions for both the native and zinc complex of bacitracin for both formation of the major degradation product (F) and loss of the active isoform (A) were consistent with longer-term measured values at 30 degrees C/53%RH and 40 degrees C/75%RH, validating this approach for accelerating the determination of long-term stability of a peptide. PMID- 27714700 TI - Assessment Methodology for Process Validation Lifecycle Stage 3A. AB - The paper introduces evaluation methodologies and associated statistical approaches for process validation lifecycle Stage 3A. The assessment tools proposed can be applied to newly developed and launched small molecule as well as bio-pharma products, where substantial process and product knowledge has been gathered. The following elements may be included in Stage 3A: number of 3A batch determination; evaluation of critical material attributes, critical process parameters, critical quality attributes; in vivo in vitro correlation; estimation of inherent process variability (IPV) and PaCS index; process capability and quality dashboard (PCQd); and enhanced control strategy. US FDA guidance on Process Validation: General Principles and Practices, January 2011 encourages applying previous credible experience with suitably similar products and processes. A complete Stage 3A evaluation is a valuable resource for product development and future risk mitigation of similar products and processes. Elements of 3A assessment were developed to address industry and regulatory guidance requirements. The conclusions made provide sufficient information to make a scientific and risk-based decision on product robustness. PMID- 27714701 TI - Comparison of Nanoemulsion and Aqueous Micelle Systems of Paliperidone for Intranasal Delivery. AB - The objective of the study was to develop and compare the efficiency of nanoemulsion and aqueous micelle system of Paliperidone on intranasal administration. Both the formulations were evaluated for physical parameters such as globule size, pH, viscosity, conductivity and in vitro drug release studies. The reduction in spontaneous motor activity of L-dopa and Carbidopa-treated Swiss Albino mice on intranasal administration of nanoemulsion and micellar system of Paliperidone was compared with plain drug suspension. Histopathological evaluation of formulation treated nasal mucosal membrane was performed. Nasal spray device was evaluated for spray pattern and volume per actuation. Globule size of micellar system and nanoemulsion was found to be 16.14 & 38.25 nm, respectively. In vitro release of drug from micellar system was found to be 1.8 fold higher than nanoemulsion. The loading of drug in nanoemulsion was found to be superior (2.5 mg/mL) when compared to micellar system (0.41 mg/mL). The spray pattern of micellar system and nanoemulsion from the device was elliptical and circular, respectively. The locomotor activity of L-dopa and Carbidopa-treated Swiss albino mice was found to be 1096.5+/-78.49, 551.5+/-13.43 and 535.5+/-24.75 counts/min in case of plain drug suspension, micellar system and nanoemulsion, respectively. The intranasal administration of developed formulations showed significant difference (p<0.01) in the locomotor activity when compared to intranasal administration of plain drug. Thus it can be concluded that both the developed formulations have shown improved in vivo activity on intranasal administration and pose great potential for delivery of Paliperidone through intranasal route. PMID- 27714702 TI - Amorphous-based controlled-release gliclazide matrix system. AB - The aim of this study was to develop a hydrophilic oral controlled release system (CRS) using the amorphous form of gliclazide, a BCS class II compound, listed on the WHO list of essential medicines. For this purpose, spray-dried dispersions (SDDs) of gliclazide were produced using various grades of hydroxypropyl methylcellulose acetate succinate (HPMCAS) or copovidone as carrier under fully automated conditions. The solid-state properties of prepared SDDs were characterized using X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), modulated differential scanning calorimetry (MDSC), and Fourier transform infrared spectroscopy (FTIR). Supersaturated micro-dissolution testing of SDDs in fasted state-simulated intestinal fluid showed prolonged supersaturation state, with solubility increases of 1.5- to 4.0-fold. Solubility and stability characteristics of the most desirable SDDs in terms of relative dissolution area under the curves (AUCs) (AUC(SDD)/AUC(crystalline)) and stable supersaturated state concentration ratio up to 180 min (C180/Cmax) were determined. The optimized gliclazide-SDD amorphous forms were included into matrix tablets with HPMC blends using compaction simulator. Developed matrix systems were subjected to standard USP dissolution testing. Dissolution profiles obtained were linear with different slopes indicating varying rates of dissolution. Six-month storage stability testing was performed, and dissolution profiles remained stable with "similarity factor" (f 2 = 85). Results show that the use of various HPMCAS as a drug carrier in the spray-drying process produces homogeneous single-phase SDDs which are stable and promising for inclusion into HPMC-based hydrophilic matrix systems. PMID- 27714704 TI - Development and evaluation of enzyme-linked immunosorbent assay of nucleic acid sequence-based amplification for diagnosis of invasive aspergillosis. AB - Invasive aspergillosis (IA) is a life-threatening infection in immunocompromised patients, rapid and sensitive detection of Aspergillus from clinical samples has been a major challenge in the early diagnosis of IA. An enzyme-linked immunosorbent assay of nucleic acid sequence-based amplification (NASBA-ELISA) was developed to fulfil the need for the efficient diagnosis of these infections. The primers targeting 18S rRNA were selected for the amplification of Aspergillus RNA by the isothermal digoxigenin (DIG)-labeling NASBA process. The DIG-labeled RNA amplicons were hybridized with a specific biotinylated DNA probe immobilized on streptavidin-coated microtiter plate. The hybrids were colorimetrically detected by the addition of an anti-DIG antibodies linked to ALP and substrate (disodium 4-nitrophenyl phosphate). The detection limit of the Aspergillus NABSA ELISA system was 1 CFU and the RNA in non-target bacteria or fungus was not amplified. The performance of this NASBA-ELISA compared to RT-PCR and galactomannan (GM) was evaluated by testing blood samples from 86 patients at high risk for IA. The sensitivity of NASBA-ELISA, RT-PCR and GM-ELISA was 80.56 % (95 % CI 63.98-91.81), 72.22 % (95 % CI 54.81-85.80), 58.33 % (95 % CI 40.76 74.49), respectively, and the specificity was 80.00 % (95 % CI 66.28-89.97), 84.00 % (95 % CI 70.89-92.83), 82.00 % (95 % CI 68.56-91.42). The efficiency of the three methods in various combinations was also evaluated. Combination of NASBA-ELISA and GM-ELISA testing achieved perfect specificity (100 %; 95 % CI 92.89-100) and perfect positive predictive value (100 %; 95 % CI 83.16-100). The best sensitivity (97.22 %; 95 % CI 85.47-99.93) and the highest Youden index (0.652) were obtained by testing with both NASBA and RT-PCR in parallel. In conclusion, the NASBA-ELISA assay consists of an alternative process for large scale samples detection with semi-quantitative results and provides good clinical performance without resorting to expensive equipment. This assay makes it possible for the NASBA based RNA diagnosis to become a routine work in laboratories in less developed countries with fewer resources. PMID- 27714703 TI - Sustained delivery of recombinant human bone morphogenetic protein-2 from perlecan domain I - functionalized electrospun poly (epsilon-caprolactone) scaffolds for bone regeneration. AB - BACKGROUND: Biomaterial scaffolds that deliver growth factors such as recombinant human bone morphogenetic proteins-2 (rhBMP-2) have improved clinical bone tissue engineering by enhancing bone tissue regeneration. This approach could be further improved if the controlled delivery of bioactive rhBMP-2 were sustained throughout the duration of osteogenesis from fibrous scaffolds that provide control over dose and bioactivity of rhBMP-2. In nature, heparan sulfate attached to core proteoglycans serves as the co-receptor that delivers growth factors to support tissue morphogenesis. METHODS: To mimic this behavior, we conjugated heparan sulfate decorated recombinant domain I of perlecan/HSPG2 onto an electrospun poly(epsilon-caprolactone) (PCL) scaffold, hypothesizing that the heparan sulfate chains will enhance rhBMP-2 loading onto the scaffold and preserve delivered rhBMP-2 bioactivity. RESULTS: In this study, we demonstrated that covalently conjugated perlecan domain I increased loading capacity of rhBMP 2 onto PCL scaffolds when compared to control unconjugated scaffolds. Additionally, rhBMP-2 released from the modified scaffolds enhanced alkaline phosphatase activity in W20-17 mouse bone marrow stromal cells, indicating the preservation of rhBMP-2 bioactivity indicative of osteogenesis. CONCLUSIONS: We conclude that this platform provides a sophisticated and efficient approach to deliver bioactive rhBMP-2 for bone tissue regeneration applications. PMID- 27714705 TI - Predictive factors of bleeding events in adults undergoing extracorporeal membrane oxygenation. AB - BACKGROUND: Bleeding is the most frequent complication associated with extracorporeal membrane oxygenation (ECMO) support in critically ill patients. Nonetheless, risk factors for bleeding have been poorly described especially those associated with coagulation anomalies and anticoagulant therapy during ECMO support. The aim of this study is to describe bleeding complications in critically ill patients undergoing ECMO and to identify risk factors for bleeding events. METHODS: We retrospectively analysed ICU charts of adults who received either veno-venous (VV) or veno-arterial (VA) ECMO support in two participating ICUs between 2010 and 2013. Characteristics of patients with and without bleeding complications, as per the Extracorporeal Life Support Organisation (ELSO) definition, were compared, and the impact of bleeding complications on patient outcomes was assessed using survival analysis. Variables that were independently associated with bleeding, including daily clinical and biological variables during ECMO courses, were modelled. RESULTS: Of the 149 ECMO episodes (111 VA ECMO and 38 VV ECMO) performed in 147 adults, 89 episodes (60 %) were complicated by at least one bleeding event. The most common bleeding sources were: ECMO cannula (37 %), haemothorax or cardiac tamponade (17 %) and ear-nose and throat (16 %). Intra-cranial haemorrhage occurred in five (2.2 %) patients. Bleeding complications were independently associated with worse survival [adjusted hazard ratio (HR) 2.17, 95 % confidence interval (CI) 1.07-4.41, P = 0.03]. Higher activated partial thromboplastin time (aPTT) [adjusted odds ratio (OR) 3.00, 95 % CI 1.64-5.47, P < 0.01], APACHE III score [adjusted OR 1.01, 95 % CI 1.01-1.02, P = 0.01] and ECMO following surgery [adjusted OR 3.04, 95 % CI 1.62-5.69, P < 0.01] were independently associated with greater risk of bleeding occurrence. A similar association between bleeding and higher aPTT was found when non-post surgical VA ECMO was considered separately. CONCLUSIONS: Bleeding events based on the ELSO bleeding definition occurred in more than 60 % of ECMO episodes and were associated with hospital mortality. We identified higher aPTT prior bleeding as an independent risk factor for bleeding event, suggesting that better control of the aPTT (through a better control of either coagulopathy or anticoagulation) may improve patients' outcome. PMID- 27714706 TI - What's new in multidrug-resistant pathogens in the ICU? AB - Over the last several decades, antibacterial drug use has become widespread with their misuse being an ever-increasing phenomenon. Consequently, antibacterial drugs have become less effective or even ineffective, resulting in a global health security emergency. The prevalence of multidrug-resistant organisms (MDROs) varies widely among regions and countries. The primary aim of antibiotic stewardship programs is to supervise the three most influential factors contributing to the development and transmission of MDROs, namely: (1) appropriate antibiotic prescribing; (2) early detection and prevention of cross colonization of MDROs; and (3) elimination of reservoirs. In the future, it is expected that a number of countries will experience a rise in MDROs. These infections will be associated with a high consumption of healthcare resources manifested by a prolonged hospital stay and high mortality. As a counteractive strategy, minimization of broad-spectrum antibiotic use and prompt antibiotic administration will aid in reduction of antibiotic resistance. Innovative management approaches include development and implementation of rapid diagnostic tests that will help in both shortening the duration of therapy and allowing early targeted therapy. The institution of more accessible therapeutic drug monitoring will help to optimize drug administration and support a patient specific approach. Areas where further research is required are investigation into the heterogeneity of critically ill patients and the need for new antibacterial drug development.

PMID- 27714708 TI - Clinical and therapeutic relevance of the metabolic oncogene fatty acid synthase in HER2+ breast cancer. AB - Fatty acid synthase (FASN) is a key lipogenic enzyme for de novo fatty acid biosynthesis and a druggable metabolic oncoprotein that is activated in most human cancers. We evaluated whether the HER2-driven lipogenic phenotype might represent a biomarker for sensitivity to pharmacological FASN blockade. A majority of clinically HER2-positive tumors were scored as FASN overexpressors in a series of almost 200 patients with invasive breast carcinoma. Re-classification of HER2-positive breast tumors based on FASN gene expression predicted a significantly inferior relapse-free and distant metastasis-free survival in HER2+/FASN+ patients. Notably, non-tumorigenic MCF10A breast epithelial cells engineered to overexpress HER2 upregulated FASN gene expression, and the FASN inhibitor C75 abolished HER2-induced anchorage-independent growth and survival. Furthermore, in the presence of high concentrations of C75, HER2-negative MCF-7 breast cancer cells overexpressing HER2 (MCF-7/HER2) had significantly higher levels of apoptosis than HER2-negative cells. Finally, C75 at non-cytotoxic concentrations significantly reduced the capacity of MCF-7/HER2 cells to form mammospheres, an in vitro indicator of cancer stem-like cells. Collectively, our findings strongly suggest that the HER2-FASN lipogenic axis delineates a group of breast cancer patients that might benefit from treatment with therapeutic regimens containing FASN inhibitors. PMID- 27714711 TI - Denervation of the renal arteries - what next? PMID- 27714707 TI - Performance of the PEdiatric Logistic Organ Dysfunction-2 score in critically ill children requiring plasma transfusions. AB - BACKGROUND: Organ dysfunction scores, based on physiological parameters, have been created to describe organ failure. In a general pediatric intensive care unit (PICU) population, the PEdiatric Logistic Organ Dysfunction-2 score (PELOD 2) score had both a good discrimination and calibration, allowing to describe the clinical outcome of critically ill children throughout their stay. This score is increasingly used in clinical trials in specific subpopulation. Our objective was to assess the performance of the PELOD-2 score in a subpopulation of critically ill children requiring plasma transfusions. METHODS: This was an ancillary study of a prospective observational study on plasma transfusions over a 6-week period, in 101 PICUs in 21 countries. All critically ill children who received at least one plasma transfusion during the observation period were included. PELOD-2 scores were measured on days 1, 2, 5, 8, and 12 after plasma transfusion. Performance of the score was assessed by the determination of the discrimination (area under the ROC curve: AUC) and the calibration (Hosmer-Lemeshow test). RESULTS: Four hundred and forty-three patients were enrolled in the study (median age and weight: 1 year and 9.1 kg, respectively). Observed mortality rate was 26.9 % (119/443). For PELOD-2 on day 1, the AUC was 0.76 (95 % CI 0.71-0.81) and the Hosmer-Lemeshow test was p = 0.76. The serial evaluation of the changes in the daily PELOD-2 scores from day 1 demonstrated a significant association with death, adjusted for the PELOD-2 score on day 1. CONCLUSIONS: In a subpopulation of critically ill children requiring plasma transfusion, the PELOD-2 score has a lower but acceptable discrimination than in an entire population. This score should therefore be used cautiously in this specific subpopulation. PMID- 27714712 TI - Transapical off-pump mitral valve repair. First experience with the NeoChord system in Poland (report of two cases). AB - BACKGROUND: Artificial chord implantation to repair a flail or prolapsing mitral valve leaflet requires open heart surgery and cardiopulmonary bypass. AIM: Transapical off-pump artificial chordae implantation is a new surgical technique proposed to treat degenerative mitral valve regurgitation. The procedure is performed using the NeoChord DS1000 system (NeoChord, Inc., St. Louis Park, MN, USA), which facilitates both implantation and lenght adjustment of the artificial chordae under two (2D)- and three (3D)-dimensional transoesophageal echocardiographic (TEE) guidance on a beating heart. METHODS: Two male patients aged 60 and 55 years with severe mitral regurgitation due to posterior leaflet prolapse underwent transapical off-pump artificial chordae implantation on September 3, 2015. The procedure was performed by left minithoracotomy under general anaesthesia in a cardiac surgical theatre, using 2D and 3D TEE guidance. RESULTS: Early procedural success as confirmed by 3D TEE was achieved in both patients, with implantation of 6 artificial chordae in the first patient and 3 artificial chordae in the second patient. Both procedures were uneventful, and no postoperative complications were noted. The patients were discharged home on the 8th and 6th postoperative day, respectively. CONCLUSIONS: The NeoChord DS1000 system allows both implantation and lenght adjustment of artificial chordae under 2D and 3D TEE guidance on a beating heart. Our initial experience in 2 patients with posterior mitral leaflet prolapse indicates that the procedure is feasible and safe. PMID- 27714713 TI - Long-term prognosis is related to mid-term changes of glucometabolic status in patients with acute myocardial infarction treated invasively. AB - BACKGROUND: Glucometabolic status (GS) in patients with acute myocardial infarction (AMI) has an impact on prognosis, but it may change over time. AIM: To evaluate the prognosis after AMI treated invasively with respect to changes in GS assessed by oral glucose tolerance test at discharge and at mid-term follow-up visit (FU-visit). METHODS: Glucometabolic status was assessed by two-hour post load glycaemia and defined as abnormal glucose tolerance (AGT) or normal glucose tolerance (NGT). Out of 454 in-hospital AMI survivors, 368 (81%) patients completed an FU-visit and were divided into four groups with respect to GS at discharge and FU-visit: group 1 - AGT at discharge and FU-visit (n = 101); group 2 - AGT at discharge and NGT at FU-visit (n = 48); group 3 - NGT at discharge and AGT at FU-visit (n = 114); and group 4 - NGT at discharge and FU-visit (n = 105). All-cause mortality was compared between groups with log-rank test. RESULTS: Median time from AMI to FU-visit was seven months. Median remote follow-up duration after AMI was 31 months. Two-hour post load glycaemia was significantly higher in patients with confirmed AGT at FU-visit than in other groups. Mortality was higher in group 1 (11.9%) than in group 2 (2.1%; p = 0.034) and group 4 (2.9%; p = 0.009). Mortality rates between group 2 and 4 were similar (2.1% vs. 2.9%; p = 0.781). There was no significant difference in mortality between group 1 and group 3 (11.9% vs. 6.1%; p = 0.114). Mortality in group 3 was over two-fold higher than in group 4; however, this difference was statistically non significant (6.1% vs. 2.9%; p = 0.247). CONCLUSIONS: Prognosis for patients with confirmed AGT was unfavourable; however, patients with AGT at discharge, in whom GS improved, had similar mortality to subjects with persistent NGT. The major clinical implication from this study is the finding that reassessment of GS by repeated oral glucose tolerance test has significant prognostic value and makes initial risk stratification performed at discharge more reliable. PMID- 27714714 TI - Evaluation of mean platelet volume and platelet distribution width in patients with asymptomatic intermediate carotid artery plaque. AB - BACKGROUND: Platelets play a significant role in the pathogenesis of atherosclerosis. In atherosclerotic plaques, the risk of plaque rupture is more crucial than the severity of the stenosis they cause. Non-calcified carotid artery plaques are more unstable than calcified plaques, and they are associated with a higher risk of rupture, thromboembolism, and consequently, stroke. AIM: The purpose of the present study is to compare calcified and non-calcified plaques that cause intermediate carotid artery stenosis, with respect to mean platelet volume (MPV) and platelet distribution width (PDW). METHODS: A total of 139 asymptomatic patients with 50-70% stenosis of the carotid artery were included in this study. Carotid Doppler ultrasound imaging and computed tomography angiography were performed to divide the carotid artery plaques into two groups as calcified and non-calcified. Patients included in the calcified (n = 73) and non-calcified (n = 66) plaque groups were compared with respect to MPV and PDW. RESULTS: Mean platelet volume was statistically significantly higher in the non-calcified plaque group compared to the cal-cified plaque group (MPV in non-calcified/calcified plaque groups [fL]: 10.0/9.0, respectively) (p < 0.01). PDW was not significantly different between the two groups (p = 0.09). Platelet count was statistically significantly higher in the calcified plaque group compared to the non-calcified plaque group (platelet count in calcified/non calcified plaque groups [103/mm3]: 250 +/- 63/226 +/- 56, respectively) (p = 0.019). Multivariate regression analysis showed that MPV was independently associ ated with non-calcified carotid artery plaque (odds ratio 5.95, 95% confidence interval 2.63-13.45, p < 0.001). CONCLUSIONS: Mean platelet volume is increased in the presence of non-calcified carotid artery plaques that cause asymp-tomatic intermediate stenosis. Increased MPV can be used as a marker to predict the risk of rupture of the non-calcified carotid artery plaques. PMID- 27714715 TI - Total coronary occlusion of infarct-related arteries in patients with non-ST elevation myocardial infarction undergoing percutaneous coronary revascularisation. AB - BACKGROUND: The prevalence and impact of total coronary occlusion of an infarct related artery (IRA) on outcomes in patients with non-ST-elevation myocardial infarction (NSTEMI) remain unclear. AIM: We evaluated the clinical significance of total coronary occlusion in NSTEMI patients. METHODS: A total of 2767 patients with NSTEMI enrolled in the Polish Registry of Acute Coronary Syndromes, who underwent percutaneous coronary interventions, were analysed. The patients were divided into two groups according to preprocedural culprit vessel thrombolysis in myocardial infarction (TIMI) flows (TIMI flow 0 - total coronary occlusion [TO]: 728, 26.3% of the patients, and TIMI flow 1-3 - non-total occlusion [non-TO]: 2039, 73.7% of the patients). RESULTS: Patients with total occlusion were younger, were more often current smokers, and had lower incidence of hypertension and diabetes mellitus. The left circumflex artery (LCx) was the major IRA in the TO group (48.1%), whereas the left anterior descending artery (LAD) was more commonly the IRA in the non-TO group (38.8%). Multivariate analysis revealed that LCx as the culprit lesion (OR +/- 95 CI 1.54 [1.26-1.89], p < 0.0001) was an independent predictor of TIMI flow 0 in IRA. In-hospital and one-month mortality occurred more frequently in the TO group (4.0% vs. 1.7%, p = 0.0005 and 5.5% vs. 3.5%, p = 0.0175, respectively), no differences in the 12-, 24-, or 36-month mortalities were observed between these groups. CONCLUSIONS: Only LCx as a culprit lesion was an independent predictor of total occlusion in IRAs. The NSTEMI patients with TO had higher in-hospital and one-month mortalities, but their long-term outcomes were similar to those of non-TO patients. PMID- 27714716 TI - Exercise-induced changes in left ventricular global longitudinal strain in asymptomatic severe aortic stenosis. AB - BACKGROUND: The management of patients with asymptomatic severe aortic stenosis (ASAS) is still under discussion. Therefore, it is advisable to search for the parameters of early damage to left ventricular (LV) function. AIM: The aim of the study was to assess exercise-induced changes in LV global longitudinal strain (GLS) in ASAS. METHODS: The ASAS group consisted of 50 patients (26 women and 24 men, aged 38.4 +/- 18.1 years) meeting the echocardiographic criteria of severe aortic stenosis (AVA < 1 cm2, AVAI < 0.6 cm2/m2, Vmax > 4 m/s, mean aortic gradient > 40 mm Hg), with normal LV ejection fraction (LVEF >= 55%) and sinus rhythm on electrocardiogram, and without significant concomitant valvular heart diseases. The control group consisted of 21 people matched for age and sex. Echocardiographic examinations and echocardiographic stress tests with the assessment of GLS using the speckle tracking imaging were performed. RESULTS: The ASAS group was characterised by statistically significantly higher LV mass index (LVMI) and higher LVEF. GLS values at rest in both groups were within normal limits but were significantly higher in the control group (-18.9 +/- 2.4% vs. 20.7 +/- 1.7%, p = 0.006). An increase in GLS at peak exercise in both groups was observed, lower in the ASAS group (the difference was not statistically significant: -0.8 +/- 3.0% vs. -2.2 +/- 3.1%, p = 0.086). Changes in GLS during exercise (DeltaGLS) did not correlate with the parameters of the severity of aortic stenosis. In the multivariate model, LVMI proved to be a factor associated with GLS at rest and during exercise. CONCLUSIONS: In patients with ASAS, GLS is a non-invasive marker of an early stage of LV myocardial damage associated with myocardial hypertrophy. An increase in GLS during exercise in the ASAS group, smaller than in the control group, indicates a preserved functional reserve of the LV myocardium but smaller than in healthy individuals. The assessment of the clinical usefulness of exercise-induced changes in GLS requires further research. PMID- 27714717 TI - Annual prognostic factors in chronic heart failure in patients over 80 years old. AB - BACKGROUND: In the elderly the most common cause of hospitalisation and the leading cause of death is heart failure (HF). AIM: The purpose was to determine prognostic factors in chronic HF (CHF) in octogenarians and nonagenarians. METHODS: The analysis included 197 consecutive patients over 80 years old (mean age 83.63 +/- 3.01 years; 46.19% men) hospitalised in 2010-2013 due to CHF. Sixty two parameters were investigated, such as: age, gender, New York Heart Asso ciation functional class, body mass index, blood pressure, other comorbidities, the parameters of the 12-lead resting electro-cardiography and the echocardiography, the results of basic laboratory tests, and selected biomarkers, including N-terminal pro-B-type natriuretic peptide, high-sensitive troponin T (hs-TnT), and high-sensitive C-reactive protein. Participants remained in a prospective follow-up for 12 months. We defined the primary endpoint as death due to cardiovascular causes and the composite endpoint, which consisted of: death due to cardiovascular causes and/or hospitalisation for exacerbation of CHF. Follow-up concerning the deaths was performed in 189 patients, composite endpoint in 168 and hospitalisation in 166. The uni- and multivariate logistic regression stepwise analysis was performed for the entire population, according to left ventricular ejection fraction (LVEF < 45% and >= 45%) and in the group with glomerular filtration rate (GFR) < 60 mL/min. RESULTS: Patients who died constituted 11.1% of the study population (21/189). In multivariate analysis four variables were independently associated with the primary endpoint: GFR (OR = 0.92), hypertension (OR = 0.19), lung diseases (OR = 9.36), and vascular diseases (OR = 6.07). In turn, in the group of patients who reached the composite endpoint (55/168; 32.7%), the only statistically significant independent variable was anaemia (OR = 4.71). In the subpopulation of patients with LVEF < 45% the prognostics for each endpoint were vascular diseases and lung diseases, and they increased the risk from 10- to 24-fold. In the subgroup of patients with LVEF >= 45% the independent variable associated with the composite endpoint was haemoglobin (OR = 0.61), in turn for death the prognostics were: white blood cell count, hs-TnT, and vascular diseases (respectively OR = 1.30; OR = 1.04; OR = 3.96). In the population with GFR < 60 mL/min variables with prognostic importance for the composite endpoint were red blood cell parameters: red blood cell distribution width (OR = 1.42) and anaemia (OR = 3.79), while for occurrence of death they were the same as for the entire population - vascular (OR = 5.16) and lung diseases (OR = 4.72). CONCLUSIONS: In patients over 80 years old with CHF, comorbidities are of important prognostic value for annual prognosis. The most aggravating factor in studied subgroups was lung disease. PMID- 27714718 TI - The efficacy and safety of valsartan and combination of valsartan and hydrochlorothiazide in the treatment of patients with mild to moderate arterial hypertension - the VICTORY trial. AB - BACKGROUND AND AIM: The aim of the trial was to establish the efficacy and safety of Valsacor(r) (valsartan) and Valsacombi(r) (combination of valsartan and hydrochlorothiazide) in a wide variety of patient populations with mild to moderate arterial hypertension. METHODS: We performed an international, multicentre, open-label, prospective trial. After one week of washout in previously treated patients, the patients were treated for 16 weeks according to the protocol. Naive patients entered the treatment period immediately. During the active treatment, four visits were planned for each patient to obtain the data for the primary and secondary efficacy endpoints analysis. The principal methods were blood pressure (BP) measurement, additionally in a subgroup of patients, assessment of erectile function. The initial dosage of valsartan 80 mg/day was titrated up to 320 mg/day to achieve the BP goal, with the addition of hydrochlorothiazide (HCTZ) in a fixed-dose combination (FDC), if needed. RESULTS: Mean +/- standard deviation changes from baseline at week 16 were -26.6 +/- 10.4 mm Hg (systolic BP) and -14.8 +/- 7.6 mm Hg (diastolic BP). A total of 91% of the patients treated with either valsartan or valsartan FDC achieved the BP goal. Adverse reactions were experienced by 7.1% of the patients, with the most common being headache (1.9%), palpitation (1.6%), dizziness (1.6%), and fatigue (1.6%), during the whole trial. CONCLUSIONS: The results of the VICTORY trial show that valsartan and valsartan FDC effectively reduce the BP in patients with mild to moderate arterial hypertension and have a good tolerability profile. PMID- 27714719 TI - Platelet distribution width predicts left ventricular dysfunction in patients with acute coronary syndromes treated with percutaneous coronary intervention. AB - BACKGROUND: The role of platelets in the pathophysiology of acute coronary syndromes (ACS) is undeniable, but precise relationships between platelet activity and treatment outcomes are a matter of continuant investigation. Among platelet indices, mean platelet volume (MPV) has proven to be a valuable predicting factor in cardiac patients. However, platelet distribution width (PDW) is reported to be a more specific marker of platelet reactivity. Thus, application of PDW in risk stratification of ACS treatment is an up-to-date subject of research. PDW values in the assessment of left ventricular (LV) function have not been previously studied. AIM: The aim of the study was to evaluate whether admission PDW can predict LV systolic function in patients with ACS treated with stent implantation. METHODS: On-admission PDW was measured in 278 consecutive patients with diagnosis of ACS, who underwent stent(s) implantation. Echocardiogram with LV ejection fraction (LVEF) estimation was performed within 24 h of percutaneous coronary intervention. Additionally, patients were under one-year follow-up, and one-year all-cause mortality was assessed. RESULTS: According to receiver-operating characteristics (ROC) analysis, a PDW value greater than 12.8 fL could predict LVEF <= 35% with sensitivity of 81% and specificity of 39% (AUC 0.614; p = 0.0177). Only a trend was noted in ROC for PDW and one-year mortality (AUC 0.608; p = 0.0815). Multivariate logistic regression analysis has shown that the PDW parameter correlates independently with both systolic heart failure with LVEF <= 35% (PDW cut-off: 12.8 fL, OR 2.8107, CI 1.1401-6.9293, p = 0.0248) and one-year mortality (PDW cut-off: 16 fL, OR 2.6750, CI 1.0190-7.0225, p = 0.0457). CONCLUSIONS: Admission PDW may serve as a simple and widely available predictor of impaired LV function in patients with ACS. Association between PDW and mortality needs to be confirmed in larger studies. PMID- 27714720 TI - The effect of epicardial adipose tissue thickness on left ventricular diastolic functions in patients with normal coronary arteries. AB - BACKGROUND AND AIM: The aim of this study is to evaluate the effect of epicardial adipose tissue (EAT) thickness on left ventricular diastolic functions in patients with normal coronary arteries (NCA) proven by angiography. METHODS: We selected study patients who were referred to coronary angiography due to typical chest pain or atypical chest pain with a positive pre-test result for coronary artery disease (CAD). After coronary angiography, 85 patients with significant coronary lesion (>= 50% stenosis) served as the CAD group, 82 patients with non significant coronary lesion (< 50% stenosis) and/or a coronary plaque served as the non-significant CAD group, and 83 patients with NCA served as the NCA group. All patients underwent transthoracic echocardiographic examination to measure EAT thickness and left ventricular diastolic properties. RESULTS: Gensini score, total cholesterol, and C-reactive protein were significantly higher in the CAD group compared to the non-significant CAD group and the NCA group. The average of EAT thickness was 7.3 +/- 2.4 mm in all groups. It was 5.8 +/- 2.3 mm in the NCA group, 6.4 +/- 2.4 mm in the non-significant CAD group, and 7.8 +/- 2.2 mm in the CAD group (p < 0.001). In correlation analyses, average EAT thickness was significantly correlated with E/e' ratio in the NCA group. In multivariate analysis, average of EAT thickness was significantly associated with left ventricular diastolic dysfunction in subjects with NCA (OR 1.019, 95% CI 1.012 1.027, p < 0.001). CONCLUSIONS: Based on our findings, EAT thickness may have an effect on left ventricular diastolic functions. This independent relationship showed us the clinical importance of measuring of EAT thickness. PMID- 27714721 TI - Basic laboratory parameters as predictors of in-hospital death in patients with acute decompensated heart failure: data from a large single-centre cohort. AB - BACKGROUND: Heart failure (HF) is a growing cause of hospitalisation worldwide, and despite significant progress in its treat-ment it is still associated with high mortality. AIM: The aim of this study was to find factors predicting in hospital death in acute decompensated HF by analysis of basic laboratory data and echocardiography, routinely collected on admission to the hospital. METHODS: To this single-centre retrospective study we involved 638 consecutive patients hospitalised in the years 2007-2008 due to acute decompensated HF. To the initial univariate analysis we included the results of echocardiography and 36 basic laboratory tests performed at hospital admission. Parameters significantly associated with in-hospital death in univariate analysis were taken to multivariate regression analysis. RESULTS: In-hospital death occurred in 119 cases (median age 75 years; 40.3% females). The multivariate analysis revealed sig-nificant association between in-hospital death and: higher leukocyte count (death [D]: 13.5 vs. survival [S]: 8.8 G/L, p < 0.01), higher neutrophil count (D: 10.5 vs. S: 5.9 G/L, p < 0.01), lower lymphocyte count (D: 1.3 vs. S: 1.7 G/L, p < 0.05), higher C-reactive protein concentration (D: 20.8 vs. S: 6.7 mg/dL, p < 0.01), higher serum glucose concentration (D: 167.0 vs. S: 116.0 mg/dL, p < 0.00001), higher serum creatinine concentration (D: 1.5 vs. S: 1.2 mg/dL, p < 0.0001), higher blood urea nitrogen concentration (D: 29.0 vs. S: 22.0 mg/dL, p < 0.00001), and higher aspartate aminotransferase (D: 72.0 vs. S: 27.0 U/L, p < 0.0001). Surprisingly, there was no significant association with echocardiographic parameters. CONCLUSIONS: Analysis of basic laboratory data collected on admission to the hospital may help to identify patients with acute decompensated HF, who are at high risk of in-hospital death. PMID- 27714722 TI - Plasmatic NT-proBNP concentrations in patients with coexistent periodontal disease and congestive heart failure: pilot studies. AB - BACKGROUND: The presented pilot study was conducted in order to evaluate dynamic fluctuations of blood inflammation markers among patients with congestive heart failure (CHF) and coexistent periodontitis (PD). AIM: The study hypothesis stated that elimination of chronic inflammation caused by PD has a significant impact on inflammation markers and, secondarily, also on the course and prognosis of CHF. N terminal pro-B-type natriuretic peptide (NT-proBNP) and tumour necrosis factor alpha (TNF-alpha) markers were assessed due to their proven diagnostic significance. METHODS: Blood samples were collected at the time of CHF patients' admission to the clinical ward (I examination) and then after 3-9 months (average six months) after periodontal treatment completion (II examination). With antibiotic cover, basic periodontal parameters (such as CAL, PD, PI, BOP) were evaluated, scaling and root-planning were performed, and orthopantomogram X-rays were conducted. Patients received instructions about domestic oral hygiene procedures. Measurements were repeated during a second examination of blood samples. Obtained results were compared and statistically analysed. RESULTS: The initial outcome of the study confirmed the hypothesis that maintaining good and complex oral hygiene has an essential impact on blood concentration of NT-proBNP and TNF-alpha markers. CONCLUSIONS: Exploration of possibilities considering medical help and treatment optimisation seems to be evident also according to improvement of prognosis, therapy effectiveness, and patient comfort. Foregoing conclusions about biomarkers are, according to authors' best knowledge, the first such results reported in medical literature. PMID- 27714723 TI - Estimation of shear stress by using a myocardial bridge-mural coronary artery simulating device. AB - BACKGROUND: This study was aimed at developing a myocardial bridge-mural coronary artery simulative device and analyzing the relationship between shear stress on the mural coronary artery and atherosclerosis. METHODS: A myocardial bridge-mural coronary artery simulative device was used to simulate experiments in vitro. In the condition of maintaining any related parameters such as system temperature, average flow rate, and heart rate, we calculated and observed changes in proximal and distal mean values, and oscillatory value of shear stress on the mural coronary artery by regulating the compression level of the myocardial bridge to the mural coronary artery. RESULTS: Under 0% compression, no significant differences were observed in distal and proximal mean values and oscillatory value of the shear stress on the mural coronary artery. With the increase in the degree of compression, the mean shear stress at the distal end was greater than that at the proximal end, but the oscillatory value of the shear stress at the proximal end was greater than that at the distal end. CONCLUSIONS: The experimental results of this study indicate that myocardial bridge compression leads to abnormal hemodynamics at the proximal end of the mural coronary artery. This abnormal phenomenon is of great significance in the study of atherosclerosis hemodynamic pathogenesis, which has potential clinical value for pathological effects and treatments of myocardial bridge. PMID- 27714724 TI - Assessment of cardiovascular function following transcatheter aortic valve implantation based on six-minute walk test. AB - BACKGROUND: Transcatheter aortic valve implantation (TAVI) is presently a recognized treatment mo-dality for patients with severe aortic stenosis ineligible for surgery. It reduces mortality as compared to the conservative treatment. It is further expected from this therapy to improve quality of life by improving of the cardiovascular function performance. The aim of this study is to compare patients' cardiovascular system efficiency in the 6-minute walk test (6MWT) made before and after TAVI and at the 6-12-month follow-up. METHODS: From January 2009 until February 2012, in the Silesian Center for Heart Diseases in Zabrze, TAVI was performed in 104 patients. Eighty-two patients who underwent 6MWT before surgery were qualified for the analysis. The average age of the patients was 76.0 +/- 9.17 years, women made 45.1%. The risk of surgical treatment according to the Logistic Euroscore averaged 22.76 +/- 12.63%, and by the Society of Thoracic Surgeons - 5.55 +/- 3.34%. The 6MWT was performed within 1 month before the TAVI procedure, up to a month after the procedure and during the 6-12-month follow-up. RESULTS: The 6-minute walk test after TAVI was performed by 64 patients, and after 6-12 month follow-up by 46 patients. The average distance in 6MWT increased from 268.4 +/- 89.0 m before treat-ment to 290.0 +/- 98.2 m after the procedure (p = 0.008) and 276.1 +/- 93.5 m to 343.1 +/ 96.7 m after 6-12 months (p < 0.0001). CONCLUSIONS: Transcatheter aortic valve implantation procedures significantly improve function of the cardiovascular system evaluated by the 6MWT in 1- and 6-12-month observations. (Cardiol J 2017; 24, 2: 167-175). PMID- 27714726 TI - The variable origin of the lateral circumflex femoral artery: a meta-analysis and proposal for a new classification system. AB - The lateral circumflex femoral artery (LCFA) is responsible for vascularisation of the head and neck of the femur, greater trochanter, vastus lateralis and the knee. The origin of the LCFA has been reported to vary significantly throughout the literature, with numerous branching patterns described and variable distances to the mid-inguinal point reported. The aim of this study was to determine the estimated population prevalence and pooled means of these anatomical characteristics, and review their associated clinical relevance. A search of the major electronic databases was performed to identify all articles reporting data on the origin of the lateral circumflex femoral artery and its distance to the mid-inguinal point. Additionally, an extensive search of the references of all relevant articles was performed. All data on origin, branching, and distance to mid-inguinal point was extracted and pooled into a meta-analysis. A total of 26 articles (n = 3731 lower limbs) were included in the meta-analysis. Lateral circumflex femoral artery most commonly originates from the deep femoral artery with a pooled prevalence of 76.1% (95% confidence interval 69.4-79.3). The deep femoral artery-derived lateral circumflex femoral artery was found to originate with a mean pooled distance of 51.06 mm (95% confidence interval 44.61-57.51 mm) from the mid-inguinal point. Subgroup analysis of both gender and limb side data were consistent with these findings. Due to variability in the lateral circumflex femoral artery's origin and distance to mid-inguinal point, anatomical knowledge is crucial for clinicians to avoid iatrogenic injuries when performing procedures in the femoral region, and thus radiographic assessment prior to surgery is recommended. Lastly, we propose a new classification system for origin of the lateral circumflex femoral artery. PMID- 27714725 TI - In vitro assessment of six aspiration catheters using a distal protection filter. AB - BACKGROUND: We assessed performance of 6 aspiration catheters for distal embolization using a distal protection filter in an in vitro experiment. In acute myocardial infarction, a distal protection filter is used for lesions likely to induce a distal embolism. Which aspiration cathether is most effective when used with a distal protection filter remains still unclear. METHODS: A 0.5-cm3 bolus of gelatin as a model of stagnant pools of coronary plaque debris was captured in the distal protection filter and aspirated by 6 aspiration catheters. We measured and compared the length of the suspended embolus matter. RESULTS: Among the 6 catheters evaluated, the use of the Export Advance catheter (Medtronic) resulted in significantly shorter lengths of the suspended embolus matter compared to the use of the TVAC II (Nipro), Thrombuster III SL (Kaneka), and Rebirth Pro (Goodman) catheters (p < 0.01). The residual embolus matter in all cases had drained distally to the distal protection filter when the filter was retrieved. CONCLUSIONS: The use of the Export Advance catheter showed better performance using a distal protection filter in this in vitro experiment, and its use might be more effective in preventing distal embolisms in combination with a distal protection filter. PMID- 27714727 TI - Anatomy of the long peroneal muscle of the leg. AB - BACKGROUND: The aim of the work was to perform a morphometric analysis of the long peroneal muscle (LPM) of the leg and explore the relationship between muscle belly and tendon. MATERIALS AND METHODS: Ten lower limbs (8 right and 2 left) were fixed in formaldehyde and dissected using standard technique. The LPM was exposed from the proximal attachment to the top of a lateral malleolus. RESULTS: The tendon was subsequently freed and various measurements were taken. The tendon of the LPM enters deep into the muscle belly. Muscle fibres surround the tendon and descend as far down as 4 cm above the lateral malleolus. Muscle fibres insert mainly along posterior border of the tendon and on its medial surface, leaving lateral surface only partly covered. CONCLUSIONS: The LPM contains a long intramuscular segment of the tendon and area of the musculotendinous junction varies along the LPM. It makes the idea of uniform pennation pattern of the LPM unlikely. PMID- 27714728 TI - Developmental parallelism in primates. AB - The authors examined a large random sample of skulls from two species of macaques: rhesus monkeys and cynomolgus monkeys. The skulls were measured, divided into age and sex groups and thoroughly analysed using statistical methods. The analysis shows that skulls of young rhesuses are considerably more domed, i.e. have better-developed neurocrania, than their adult counterparts. Male and female skulls, on the other hand, were found to be very similar, which means that sexual dimorphism of the rhesus macaque was suppressed. Both of these patterns are known from the human evolutionary pattern. No such parallelism to the development of Homo sapiens was found in the cynomolgus monkeys. The authors conclude that mosaic hominisation trends may have featured in the evolution of all primates. This would mean that apes were not a necessary step on the evolutionary way leading to the development of Homo sapiens, who may have started to evolve at an earlier stage of monkeys. PMID- 27714729 TI - What can anthropometric measurements tell us about obstructive sleep apnoea? AB - BACKGROUND: Clinical detection of anatomic narrowing of the upper airway may facilitate early recognition of obstructive sleep apnoea (OSA). The aim of this study was to investigate whether anthropometric measurement can be used to predict OSA. MATERIALS AND METHODS: One hundred forty-seven subject were included from those patients who were referred to our sleep laboratory with suspected sleep apnoea. All patients were divided two groups with respect to the apnoea hypopnoea index (AHI). The first group was diagnosed as OSA, AHI greater than 5. The second group was not diagnosed with OSA, AHI less than 5 (non-OSA control). Anthropometric measurements such as lower face height (LFH), interincisial distance, nose height, anterior neck height (ANH), lateral neck height, posterior neck height (PNH), ramus mandible height, corpus mandible height (CML), bigonial distance (BGD), neck width, and neck depth were assessed. RESULTS: Patients with OSA had higher body mass index (BMI) and larger LFH, ANH, thyromental distance, CML, BGD, and neck circumference than those without OSA (p < 0.0001, p < 0.0001, p < 0.0001, p < 0.0001, p < 0.0001, p = 0.023, p < 0.0001, respectively). There was no difference between the two groups in terms of other parameters. CONCLUSIONS: In this study, it was determined that BMI, lower face height, neck height, mandible length, bigonial width, thyromental distance and neck circumference are in significant relationship with sleep disordered breathing. Thus, these measurements may be used in clinical practice for prediction of OSA. PMID- 27714730 TI - Anatomic assessment of the left main bifurcation and dynamic bifurcation angles using computed tomography angiography. AB - BACKGROUND: An understanding of the left main coronary artery (LMCA) anatomy is important for accurate diagnosis and therapy. We aimed to investigate LMCA anatomy via 128-multisliced coronary computed-tomography-angiography (CCTA) in patients with normal LMCA. MATERIALS AND METHODS: A total of 201 CCTA studies were included in this study. Anatomical features of LMCA including cross sectional areas of the LMCA ostial, LMCA distal, left anterior descending artery (LAD) ostial and left circumflex artery (LCX) ostial, and degree of tapering and LMCA bifurcation angles (BA) in the form of LMCA-LCX BA, LMCA-LAD BA, LAD-LCX BA at end-diastole and end-systole. RESULTS: The mean age was 55 +/- 11; 55.7% of patients were males. Right coronary artery was dominant in 173 (86.1%) patients. Mean LMCA length was 10.0 +/- 4.5 mm. The mean values of LMCA ostial, LMCA distal, LAD ostial and LCX ostial areas were 18.2 +/- 5.1 mm2, 13.2 +/- 4.0 mm2, 9.0 +/- 3.2 mm2 and 7.6 +/- +/- 2.8 mm2, respectively. LMCA ostial-distal area, LMCA distal-LAD ostial area and LMCA distal-LCX ostial area ratios were >= 1.44 - < 1.69 in 47 (23.4%), 53 (26.4%), 47 (23.4%) patients, respectively, and were >= 1.69 - < 1.96 in 19 (9.5%), 24 (11.9%), 40 (19.9%) patients respectively. Systolic motion modifies LMCA BAs; systolic motion begets an increment of LMCA LAD angle in 72.6% of patients and decrement of LAD-LCX angle in 75.6% of patients. Patients with T-shaped LAD-LCX BA was shown to have significantly longer LMCA, larger LAD ostial area, larger LCX ostial area and higher diastolic to-systolic range (DSR) of LAD-LCX BA compared to patients with Y-shaped LAD-LCX BA. CONCLUSIONS: LMCA with T-shaped distal BA was found to have significantly longer LMCA, larger LAD ostial area, larger LCX ostial area and higher DSR of distal BA compared to patients with Y-shaped distal BA. These findings may provide useful information for LMCA bifurcation stenting or designing dedicated stents for LMCA. PMID- 27714731 TI - An anatomical investigation of the carotid canal. AB - BACKGROUND: The carotid canal (CC) located in the petrous temporal bone transmits the internal carotid artery, internal carotid venous plexus and sympathetic nerve plexus from the neck into the cranial cavity. It is an accessible passage into the cranial cavity and is considered an important anatomical landmark for neurosurgeons. The aim of this study was to investigate the topographical, morphometric and morphological parameters of the CC. MATERIALS AND METHODS: An examination of the CC and related adjacent structures in 81 dry skull specimens was performed. Distribution of sample by sex was 34 females and 47 males, and by race 77 African and 4 Caucasian. The mean age was 50 years (range: 14-100 years). RESULTS: The external opening of the CC was found to be round-shaped, oval-shaped and tear-drop-shaped in 28.4%, 49.4% and 22.2% of the specimens, respectively. (1) Mean diameters [mm]: (a) medio-lateral 7.52 mm and (b) antero-posterior 5.41mm. Statistically significant difference in the vertical diameter was recorded in the race groups and laterality of the samples. (2) Mean distances [mm] between: (a) medial margins of external opening of CC was 50.03 mm, (b) lateral margins of external opening of CC was 62.73 mm and (c) external openings of CC and foramen lacerum was 15.6 mm. There was a statistically significant correlation between race and location of the opening of external CC in relation to foramen lacerum (viz. postero-lateral, lateral and diagonal, and lateral). CONCLUSIONS: The present study corroborated previous reports on the CC; however, the tear-drop shaped external CC opening was a unique finding. The knowledge of the reference measurements pertaining to the CC and its relationship to adjacent structures may postulate a suitable surgical "safe-zone" range within the CC area.

AB - Anatomic variations of axillary artery branches are commonly encountered during radiological investigation and surgical operations. Their existence can confuse interpretation of radiological results and lead to undesired complications during surgery. In this report authors describe a rare case of a subscapular arterial trunk that gave origin to thoracodorsal, circumflex scapular, posterior humeral circumflex, and lateral thoracic artery. Such a variation might cause undesired sequelae during trauma management and a variety of common flap harvesting operations including latissimus dorsi, scapular and parascapular flaps. Furthermore it presents embryological interest as it gives insight to embryologic development of axillary area. PMID- 27714733 TI - Enthesopathic patterns of two South African female cadavers. AB - Enthesopathy is considered to be an osseous phenomenon, either disease-specific or bone-site specific, which occurs at the enthesis of bone. Upon routine cadaveric dissection of the glenohumeral region in two Caucasian females, enthesopathy of the right proximal humerus was observed unilaterally in both cases. Case 1 exhibited an inconsistent pattern of bony protuberances and crests dispersed across the lesser and greater tuberosities of the right humeral head. Varying degrees of ossification of the distal subscapularis muscle was also observed. Case 2 presented with a distinctively large enthesophyte that protruded supero-medially from the proximal right humerus. In addition, ossification of the distal-most aspect of the supraspinatus muscle was identified. Cases 1 and 2 were both reflective of osteophytic enthesopathy as proliferative change was clearly visible on the proximal aspect of each humerus. Whilst the presence of enthesopathies may be indicative of underlying pathology, it may prove beneficial to the field of bioarchaeology for the remodelling of lifestyles of ancient civilizations through the provision of current day variations as seen in these two case studies.

PMID- 27714736 TI - Estimation of influenza and severe acute respiratory illness incidence (burden) in three provinces of the Islamic Republic of Iran, 2012 and 2013. AB - There are few estimates of influenza burden in the WHO Region for the Eastern Mediterranean. In this study we estimated the burden of severe acute respiratory infection (SARI) and influenza-associated SARI (F-SARI) in selected provinces of Islamic Republic of Iran, the trends of SARI and confirmed cases of influenza (F SARI) over 12 months (seasonality), and the age groups most at risk. Using the electronic Iranian influenza surveillance system and data of cases in sentinel hospitals of 3 selected provinces, we estimated the monthly trend (seasonality) of incidence for SARI and F-SARI, overall incidence of SARI and F-SARI and their disaggregation by age with the aid using the Monte Carlo technique. The age groups most at-risk were children aged under 2 years and adults older than 50 years.

AB - This study aims to describe etiological agents, demographic details of patients, seasonality and underlying conditions among patients hospitalized due to viral severe acute respiratory infection (SARI) in Yemen. We carried out a retrospective descriptive analysis of data from January 2014 to December 2015. Nasopharyngeal swabs were taken from each patient for laboratory testing. A total of 1346 diagnostic specimens were tested, of which 733 (54%) were positive for influenza viruses. Influenza A(H3) and A(H1N1) pdm09 predominated. Respiratory syncytial virus (RSV) was reported predominantly among children (41%). Males (61%) were more affected than females. The median age was 1 year (range 0.5 94.0). The median length of hospitalization was 6 days. Chronic cardiovascular disease was the most commonly reported underlying condition, but 67% had no documented underlying disease. Respiratory viruses, particularly RSV, adenovirus and influenza, were commonly associated with hospitalization for SARI.

AB - The World Health Organization (WHO) formulates recommendations for viruses to be included in vaccines for the influenza seasons in the northern and southern hemispheres on the basis of analyses by its collaborating centres (CCs). This report describes the contribution of influenza laboratories and national influenza centres in countries in the WHO Region for the Eastern Mediterranean to the selection process of seasonal and pre-pandemic influenza virus subtypes. Data submitted by 22 countries to FluNet and FluID between September 2010 and June 2015 were analysed. National Influenza Centres (NICs) in 12 countries (55%) reported data, 5 (23%) to both FluNet and FluID and 7 (32%) only to FluNet. The WHO CC in London characterized 78% of the samples, and the CC in Atlanta, characterized 21%. The contribution of influenza laboratories and NICs from this Region to global influenza surveillance is appreciable. However, enhancing the contribution through initiatives such as the Pandemic Influenza Preparedness Framework is still needed. PMID- 27714739 TI - Detection of influenza B viruses with reduced sensitivity to neuraminidase inhibitor in Morocco during 2014/15 season. AB - We monitored phenotypic and genotypic susceptibility of influenza viruses circulating in Morocco during 2014-2015 to oseltamivir and zanamivir. Throat and nasal swab specimens were collected from outpatients (with influenza-like illness) and inpatients (with severe acute respiratory illness) and tested for influenza viruses using real-time reverse transcription polymerase chain reaction. Positive samples were inoculated in MDCK cells and virus phenotypic susceptibility to neuraminidase inhibitors (NAIs) was assessed using fluorescent NA inhibition. Of 440 specimens, 135 were positive for influenza B Yamagata-like virus, 38 were A(H1N1)pdm09 and 25 were A(H3N2). Sixty influenza B viruses isolated from MDCK cells showed no significant resistance to NAIs. However, two of these strains, B/Morocco/176H/2015 and B/Morocco/CP10/2015, showed reduced susceptibility to oseltamivir. The two influenza B viruses with reduced susceptibility to oseltamivir show that ongoing NAI susceptibility surveillance is essential. PMID- 27714740 TI - Modelling of seasonal influenza and estimation of the burden in Tunisia. AB - The burden of influenza was estimated from surveillance data in Tunisia using epidemiological parameters of transmission with WHO classical tools and mathematical modelling. The incidence rates of influenza-associated influenza like illness (ILI) per 100 000 were 18 735 in 2012/2013 season; 5536 in 2013/14 and 12 602 in 2014/15. The estimated proportions of influenza-associated ILI in the total outpatient load were 3.16%; 0.86% and 1.98% in the 3 seasons respectively. Distribution of influenza viruses among positive patients was: A(H3N2) 15.5%; A(H1N1)pdm2009 39.2%; and B virus 45.3% in 2014/2015 season. From the estimated numbers of symptomatic cases, we estimated that the critical proportions of the population that should be vaccinated were 15%, 4% and 10% respectively. Running the model for the different values of R0, we quantified the number of symptomatic clinical cases, the clinical attack rates, the symptomatic clinical attack rates and the number of deaths. More realistic versions of this model and improved estimates of parameters from surveillance data will strengthen the estimation of the burden of influenza. PMID- 27714741 TI - An outbreak of Middle East Respiratory Syndrome (MERS) due to coronavirus in Al Ahssa Region, Saudi Arabia, 2015. AB - Between 19 April and 23 June 2015, 52 laboratory-confirmed cases of Middle East Respiratory Syndrome due to coronavirus (MERS) were reported from Al-Ahssa region, eastern Saudi Arabia. The first seven cases occurred in one family; these were followed by 45 cases in three public hospitals. The objectives of this investigation were to describe the epidemiological characteristic of the cluster and identify potential risk factors and control measures to be instituted to prevent further occurrence of MERS. We obtained the medical records of all confirmed cases, interviewed the members of the affected household and reviewed the actions taken by the health authorities. All the cases were connected. The index case was a 62-year-old man with a history of close contact with dromedary camels; three of the seven infected family members and 18 people in hospitals died (case-fatality rate, 40.4%). The median incubation period was about 6 days. The cluster of cases appeared to be due to high exposure to MERS, delayed diagnosis, inadequate risk communication and inadequate compliance of hospital health workers and visitors with infection prevention and control measures. PMID- 27714742 TI - Capacity of the national influenza surveillance system in Afghanistan, a chronic conflict setting. AB - Influenza surveillance is needed to monitor potential public health threats from the emergence of novel influenza viruses. This study assessed the capacity and performance of the national influenza surveillance system in Afghanistan from 2007 to 2014. Data were collected by review of hospital registers and the National Influenza Centre (NIC) database, interviews with influenza focal points at 9 influenza sentinel surveillance sites and the Centre staff, and observation of the sites. Out of 6900 specimens collected, influenza virus was detected in 253 (3.6%), predominantly H1N1 (63%); most of these cases were detected during the 2009 pandemic. The NIC had the capacity for virus isolation and PCR identification and performed reasonably until 2011 when support of the Naval American Medical Research Unit 3 was withdrawn. The limitations identified in the system indicated the need for: more complete data, improved technical competence and trained human resources, updating of the infrastructure/facilities, and the presence of standard operating procedures throughout surveillance. PMID- 27714743 TI - Circulation of Respiratory Syncytial Virus in Morocco during 2014-2016: Findings from a sentinel-based virological surveillance system for influenza. AB - Respiratory syncytial virus (RSV) is a leading cause of mortality and morbidity in young infants, little was known on its circulation types and patterns in Morocco. We conducted a prospective study using sentinel-based influenza surveillance to detect RSV by real time PCR in patients with acute respiratory infections, enrolled during two seasons (2014/15, 2015/16). During September 2014 April 2016, we obtained 1450 specimens, of which 267(18.4%) tested positive for RSV. The proportion of positive RSV infection was higher in patients hospitalized with acute respiratory infection compared to those with mild symptoms in out patient clinics. The proportion of RSV infection was highest in children aged 0-6 months (45%; P < 0.001). Higher positivity rate was observed between months of December and March. RSV remains important viral etiological agent causing influenza-like illness and severe acute respiratory infections especially among infants in Morocco. Further surveillance, is required to understand better the risk factors of RSV infections. PMID- 27714744 TI - Molecular epidemiology and evolution of A(H1N1) pdm09 and H3N2 viruses in Jordan, 2011-2013. AB - Understanding the genetic evolution of A(H1N1)pdm09 and H3N2 viruses can help better select strains to be included in the annual influenza vaccine. There is little information on their evolution in Jordan so this study investigated the genetic and antigenic variability of A(H1N1)pdm09 and H3N2 viruses in Jordan by performing phylogenetic and genetic analyses of the HA and NA genes of A(H1N1)pdm09 and H3N2 viruses between 2011 and 2013. The full HA and NA genes of 16 H1N1-positive samples obtained in our study and 21 published HA sequences and 20 published NA sequences from Jordanian viruses that were available on online gene databases were analysed. For H3N2, we generated 20 HA and 19 NA sequences and included 19 published HA and NA sequences each in the analysis. Jordanian H1N1 viruses had mutations that are characteristic of antigenic group 6 while H3N2 virus mutations belonged to group 3. No markers of resistance to oseltamivir were detected. The individual mutations are described in detail. PMID- 27714745 TI - Incidence of influenza virus-associated severe acute respiratory infection in Damanhour district, Egypt, 2013. AB - The epidemiology, seasonality and risk factors for influenza virus infection remains poorly defined in countries such as Egypt. Between 1 January and 31 December 2013, we used surveillance data on patients hospitalized with severe acute respiratory infection in three Egyptian government hospitals in Damanhour district to estimate the incidence rate of laboratory-confirmed seasonal influenza. Samples were taken from 1727 of 1856 patients; of these, 19% were influenza virus positive. The overall incidence of influenza virus-associated SARI during the study period was estimated to be 44 cases per 100 000 person years (95% CI: 39-48). The highest incidence of 166 cases per 100 000 person year (95% CI: 125-220) was observed in children aged 2 to 4 years. The incidence of influenza-virus associated SARI cases in pregnant women was estimated to be 17.3 cases per 100 000 person-years (95% CI: 6-54). Majority of influenza virus associated SARI occurred in autumn and early winter, and influenza A(H3N2) virus predominated. This was the first ever description of the epidemiology of seasonal influenza in Egypt. However, additional works are needed for greater understanding of influenza burden in Egypt. PMID- 27714746 TI - Burden of acute respiratory disease of epidemic and pandemic potential in the WHO Eastern Mediterranean Region: A literature review. AB - There are gaps in the knowledge about the burden of severe respiratory disease in the Eastern Mediterranean Region (EMR). This literature review was therefore conducted to describe the burden of epidemicand pandemic-prone acute respiratory infections (ARI) in the Region which may help in the development of evidence based disease prevention and control policies. Relevant published and unpublished reports were identified from searches of various databases; 83 documents fulfilled the search criteria. The infections identified included: ARI, avian influenza A(H5N1), influenza A(H1N1)pdm09 and Middle East respiratory syndrome coronavirus (MERS-CoV) infection. Pneumonia and ARIs were leading causes of disease and death in the Region. Influenza A(H1N1) was an important cause of morbidity during the 2009 pandemic. This review provides a descriptive summary of the burden of acute respiratory diseases in the Region, but there still remains a lack of necessary data. PMID- 27714747 TI - Influenza virus positivity and circulating subtypes among cases of influenza-like illness and severe acute respiratory infection, Egypt, 2012-2015. AB - Information on the prevalence of influenza, circulating virus subtypes and seasonality is essential for selecting strains for annual vaccines and for planning immunization programmes. Data were obtained from the 13 sentinel surveillance sites throughout Egypt during 2012-2015. Laboratory-confirmed influenza was found in 13% of cases of influenza-like illness (ILI) and 18% of cases of severe acute respiratory infection (SARI); positivity for influenza was similar in cases of ILI and SARI in patients up to 15 years of age but increased for SARI and decreased for ILI in people aged >= 15 years. The most commonly observed influenza virus subtypes were B followed by A/ H3 in ILI cases, and A/H1N1 followed by B in SARI cases. The seasonality of influenza in ILI cases was November- February, and that in SARI cases was November-March, peaking in January. PMID- 27714748 TI - Middle East respiratory syndrome coronavirus: current knowledge and future considerations. AB - A literature review of publically available information was undertaken to summarize current understanding and gaps in knowledge about Middle East respiratory syndrome coronavirus (MERS-CoV), including its origin, transmission, effective control measures and management. Major databases were searched and relevant published papers and reports during 2012-2015 were reviewed. Of the 2520 publications initially retrieved, 164 were deemed relevant. The collected results suggest that much remains to be discovered about MERS-CoV. Improved surveillance, epidemiological research and development of new therapies and vaccines are important, and the momentum of recent gains in terms of better understanding of disease patterns should be maintained to enable the global community to answer the remaining questions about this disease. PMID- 27714749 TI - Characterization of influenza outbreaks in Lebanon during the 2013/14 and 2014/15 seasons. AB - Despite the significant burden of influenza outbreaks, active disease monitoring has been largely absent in the Middle East, including Lebanon. In this study we characterized influenza virus in 440 nasopharyngeal swabs collected from patients with acute respiratory infections during two influenza seasons in Lebanon. Influenza A(H3N2) was dominant in the 2013/14 season while the A(H1N1)pdm09 and B/Yamagata strains were most prevalent in the 2014/15 season. All tested isolates were susceptible to 4 neuraminidase inhibitors (oseltamivir, zanamivir, peramivir and laninamivir). Genetic analysis of the haemagglutinin gene revealed multiple introductions of influenza viruses into Lebanon from different geographic sources during each season. Additionally, large data gaps were identified in the Middle East region, as indicated by the lack of current influenza sequences in the database from many countries in the region. PMID- 27714750 TI - The H1N1 influenza pandemic of 2009 in the Eastern Mediterranean Region: lessons learnt and future strategy. AB - A novel strain of influenza A virus H1N1 surfaced in Mexico in April 2009 and quickly spread across the globe, turning an epidemic into a pandemic. Within two months, the World Health Organization (WHO) declared an international health emergency and raised the threat bar from level V to level VI, i.e. containment to mitigation. During this time, the WHO Regional Office for the Eastern Mediterranean worked closely with its Member States, other stakeholders and WHO headquarters to manage the situation. This report examines the steps taken as part of this response. Programme documents were reviewed and key personnel interviewed for this study. A hallmark of the response was the establishment of the Strategic Health Operations Centre to bring together experts from different technical backgrounds at regional level. Several lessons were learnt that can provide the basis for standard operating procedures, protocols and guidelines for emergency events in future. PMID- 27714751 TI - Active surveillance of avian influenza viruses in Egyptian poultry, 2015. AB - Surveillance for avian influenza viruses in Egyptian poultry has been conducted since 2009. Up to 2011, all the detected viruses were H5N1, and the overall prevalence was 5%. In 2011, H9N2 viruses were observed to be co-circulating and co-infecting the same hosts as H5N1 viruses. Since then, the detection rate has increased to around 10%. In the 2014-2015 winter season, H5N1 was circulating heavily in poultry flocks and caused an unprecedented number of human infections. In contrast, surveillance in the last quarter of 2015 indicated a near absence of H5N1 in Egyptian poultry. Surveillance for avian influenza viruses must continue in Egypt to monitor further developments in H5N1 circulation in poultry. PMID- 27714752 TI - A new paradigm in global health security.

PMID- 27714754 TI - Paravertebral block and persistent postoperative pain after breast surgery: meta analysis and trial sequential analysis. AB - We examined whether paravertebral block has an effect on the prevalence of persistent postsurgical pain after breast surgery. Seven randomised, controlled trials (559 patients) which had the outcome assessor blinded were included, comparing patients who received paravertebral blocks after breast surgery with patients who did not. The risk ratio (95% CI) was 0.75 (0.48-1.15) for the incidence of postoperative pain at 3 months (four studies, 317 patients); the risk ratio (95% CI) obtained from three studies including 301 patients reporting on pain after 6 months was 0.57 (0.29-1.72), and the risk ratio (95% CI) for pain after 12 months (three trials, 237 patients) was 0.42 (0.15-1.23). Conventional meta-analysis using the random effects model thus showed no statistically significant risk reduction for persistent postoperative pain at 3 months, 6 months or 12 months. Trial sequential analysis, used to consider the risk of type 1 and type 2 random error, showed that at 3 months, 6 months and 12 months, the number of subjects in the analyses were only 18.3%, 6.8% and 4.2% of the required information sizes at those time points, respectively. Our study is the first to evaluate data on pain 12 months postoperatively. Trial sequential analysis revealed that the current evidence is not sufficient to reach a conclusion. These findings stand in contrast to previous meta-analyses with fewer studies that had concluded that paravertebral block effectively reduces chronic pain. PMID- 27714755 TI - Peri-operative management of anticoagulation and antiplatelet therapy. PMID- 27714756 TI - Cardiovascular pharmacogenetics: a promise for genomically-guided therapy and personalized medicine. AB - Cardiovascular disease (CVD) is the leading cause of death worldwide. The basic causes of CVD are not fully understood yet. Substantial evidence suggests that genetic predisposition plays a vital role in the physiopathology of this complex disease. Hence, identification of genetic contributors to CVD will likely add diagnostic accuracy and better prediction of an individual's risk. With high throughput genetics and genomics technology and newer genome-wide study approaches, a number of genetic variations across the human genome were uncovered. Evidence suggests that genetic defects could influence CVD development and inter-individual responses to widely used cardiovascular drugs like clopidogrel, aspirin, warfarin, and statins, and therefore, they may be integrated into clinical practice. If clinically validated, better understanding of these genetic variations may provide new opportunities for personalized diagnostic, pharmacogenetic-based drug selection and best treatment in personalized medicine. However, numerous gaps remain unsolved due to the lack of underlying pathological mechanisms for how genetic predisposition could contribute to CVD. This review provides an overview of the extraordinary scientific progress in our understanding of genetic and genomic basis of CVD as well as the development of relevant genetic biomarkers for this disease. Some of the actual limitations to the promise of these markers and their translation for the benefit of patients will be discussed. PMID- 27714758 TI - A randomised, controlled, double blind, non-inferiority trial of ultrasound guided fascia iliaca block vs. spinal morphine for analgesia after primary hip arthroplasty. AB - We performed a single centre, double blind, randomised, controlled, non inferiority study comparing ultrasound-guided fascia iliaca block with spinal morphine for the primary outcome of 24-h postoperative morphine consumption in patients undergoing primary total hip arthroplasty under spinal anaesthesia with levobupivacaine. One hundred and eight patients were randomly allocated to receive either ultrasound-guided fascia iliaca block with 2 mg.kg-1 levobupivacaine (fascia iliaca group) or spinal morphine 100 MUg plus a sham ultrasound-guided fascia iliaca block using saline (spinal morphine group). The pre-defined non-inferiority margin was a median difference between the groups of 10 mg in cumulative intravenous morphine use in the first 24 h postoperatively. Patients in the fascia iliaca group received 25 mg more intravenous morphine than patients in the spinal morphine group (95% CI 9.0-30.5 mg, p < 0.001). Ultrasound guided fascia iliaca block was significantly worse than spinal morphine in the provision of analgesia in the first 24 h after total hip arthroplasty. No increase in side-effects was noted in the spinal morphine group but the study was not powered to investigate all secondary outcomes. PMID- 27714757 TI - The protective effect of the natural compound hesperetin against fulminant hepatitis in vivo and in vitro. AB - BACKGROUND AND PURPOSE: Liver diseases are mostly accompanied by inflammation and hepatocyte death. Therapeutic approaches targeting both hepatocyte injury and inflammation are not available. Natural compounds are considered as potential treatment for inflammatory liver diseases. Hesperetin, a flavonoid component of citrus fruits, has been reported to have anti-inflammatory properties. The aim of this study was to evaluate the cytoprotective and anti-inflammatory properties of hesperetin both in vitro and in models of fulminant hepatitis. EXPERIMENTAL APPROACH: Apoptotic cell death and inflammation were induced in primary cultures of rat hepatocytes by bile acids and cytokine mixture respectively. Apoptosis was quantified by caspase-3 activity and necrosis by LDH release. The concanavalin A (ConA) and D-galactosamine/LPS (D-GalN/LPS) were used as models of fulminant hepatitis. Liver injury was assessed by alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, liver histology and TUNEL assay and inflammation by inducible NOS (iNOS) expression. KEY RESULTS: Hesperetin blocked bile acid-induced apoptosis and cytokine-induced inflammation in rat hepatocytes. Moreover, hesperetin improved liver histology and protected against hepatocyte injury in ConA- and D-GalN/LPS-induced fulminant hepatitis, as assessed by TUNEL assay and serum AST and ALT levels. Hesperetin also reduced expression of the inflammatory marker iNOS and the expression and serum levels of TNFalpha and IFN gamma, the main mediators of cell toxicity in fulminant hepatitis. CONCLUSION AND IMPLICATIONS: Hesperetin has anti-inflammatory and cytoprotective actions in models of acute liver toxicity. Hesperetin therefore has therapeutic potential for the treatment of inflammatory liver diseases accompanied by extensive hepatocyte injury, such as fulminant hepatitis. PMID- 27714759 TI - Prevalence of human papillomavirus infection among women in rural Nepal. AB - INTRODUCTION: In this study we aimed to determine the overall and type-specific prevalence of cervical human papillomavirus (HPV) infection and risk factors for such infection among women in rural Nepal, and to investigate the distribution of HPV infection by cervical cytology. MATERIAL AND METHODS: The study was conducted among women aged >=15 years in five rural villages within Kavre District in Nepal. Sociodemographic data and information on risk factors for cervical cancer were obtained through an interview, and a cervical specimen was collected for HPV DNA detection and typing using the AnyplexTM ll HPV28 Detection system, and for Papanicolaou test. RESULTS: Among the 1289 women in whom a valid HPV result was obtained the median age was 40 years (range 17-86 years). Overall, the HPV prevalence was 14.4%, 7.9% for high-risk and 6.5% for low-risk HPV types, and was similar between age groups. The five most common HR types were HPV-18 (2.3%), HPV 51 (1.2%), HPV-59 (1.1%), HPV-31 (0.9%), and HPV-16 (0.8%). The prevalence of high-risk types in women with and without abnormal cytology was 8.3 and 7.7%, respectively. HPV infection was associated with current smoking, formal education, and being married to a husband with at least one previous marriage. CONCLUSIONS: This is the first population-based study to report the prevalence of a broad range of HPV types among women from rural Nepal. These data are crucial for development of preventive strategies to reduce cervical cancer burden in the country.

PMID- 27714760 TI - Role of oxidative stress in oxaliplatin-induced enteric neuropathy and colonic dysmotility in mice. AB - BACKGROUND AND PURPOSE: Oxaliplatin is a platinum-based chemotherapeutic drug used as a first-line therapy for colorectal cancer. However, its use is associated with severe gastrointestinal side-effects resulting in dose limitations and/or cessation of treatment. In this study, we tested whether oxidative stress, caused by chronic oxaliplatin treatment, induces enteric neuronal damage and colonic dysmotility. EXPERIMENTAL APPROACH: Oxaliplatin (3 mg.kg-1 per day) was administered in vivo to Balb/c mice intraperitoneally three times a week. The distal colon was collected at day 14 of treatment. Immunohistochemistry was performed in wholemount preparations of submucosal and myenteric ganglia. Neuromuscular transmission was studied by intracellular electrophysiology. Circular muscle tone was studied by force transducers. Colon propulsive activity studied in organ bath experiments and faeces were collected to measure water content. KEY RESULTS: Chronic in vivo oxaliplatin treatment resulted in increased formation of reactive oxygen species (O2 -), nitration of proteins, mitochondrial membrane depolarisation resulting in the release of cytochrome c, loss of neurons, increased inducible NOS expression and apoptosis in both the submucosal and myenteric plexuses of the colon. Oxaliplatin treatment enhanced NO-mediated inhibitory junction potentials and altered the response of circular muscles to the NO donor, sodium nitroprusside. It also reduced the frequency of colonic migrating motor complexes and decreased circular muscle tone, effects reversed by the NO synthase inhibitor, Nomega-Nitro-L-arginine. CONCLUSION AND IMPLICATIONS: Our study is the first to provide evidence that oxidative stress is a key player in enteric neuropathy and colonic dysmotility leading to symptoms of chronic constipation observed in oxaliplatin-treated mice. PMID- 27714762 TI - Reductions in Medication-Related Hospitalizations in Older Adults with Medication Management by Hospital and Community Pharmacists: A Quasi-Experimental Study. AB - OBJECTIVES: To evaluate the association between a system of medication management services provided by specially trained hospital and community pharmacists (Pharm2Pharm) and rates and costs of medication-related hospitalization in older adults. DESIGN: Quasi-experimental interrupted time series design comparing intervention and nonintervention hospitals using a mixed-effects analysis that modeled the intervention as a time-dependent variable. SETTING: Sequential implementation of Pharm2Pharm at six general nonfederal acute care hospitals in Hawaii with more than 50 beds in 2013 and 2014. All five other such hospitals served as a contemporaneous comparison group. PARTICIPANTS: Adult inpatients who met criteria for being at risk for medication problems (N = 2,083), 62% of whom were aged 65 or older. INTERVENTION: A state-wide system of medication management services provided by specially trained hospital and community pharmacists serving high-risk individuals from hospitalization through transition to home and for up to 1 year after discharge. MEASUREMENTS: Medication-related hospitalization rate per 1,000 admissions of individuals aged 65 and older, adjusted for case mix; estimate of costs of hospitalizations and actual costs of pharmacist services. RESULTS: The predicted, case mix-adjusted medication-related hospitalization rate of individuals aged 65 and older was 36.5% lower in the Pharm2Pharm hospitals after implementation than in the nonintervention hospitals (P = .01). The estimated annualized cost of avoided admissions was $6.6 million. The annual cost of the pharmacist services for all Pharm2Pharm participants was $1.8 million. CONCLUSION: The Pharm2Pharm model was associated with an estimated 36% reduction in the medication-related hospitalization rate for older adults and a 2.6:1 return on investment, highlighting the value of pharmacists as drug therapy experts in geriatric care. PMID- 27714763 TI - Amiselimod, a novel sphingosine 1-phosphate receptor-1 modulator, has potent therapeutic efficacy for autoimmune diseases, with low bradycardia risk. AB - BACKGROUND AND PURPOSE: We conducted preclinical and clinical studies to examine the pharmacological, particularly cardiac, effects of amiselimod (MT-1303), a second-generation sphingosine 1-phosphate (S1P) receptor modulator, designed to reduce the bradycardia associated with fingolimod and other S1P receptor modulators. EXPERIMENTAL APPROACH: The selectivity of the active metabolite amiselimod phosphate (amiselimod-P) for human S1P receptors and activation of G protein-coupled inwardly rectifying K+ (GIRK) channels in human atrial myocytes were assessed. Its cardiac distribution was determined in rats, and cardiovascular telemetry was assessed in monkeys. We also examined the pharmacokinetics, pharmacodynamics and safety of amiselimod in healthy humans. KEY RESULTS: Amiselimod-P showed potent selectivity for S1P1 and high selectivity for S1P5 receptors, with minimal agonist activity for S1P4 and no distinct agonist activity for S1P2 or S1P3 receptors and approximately five-fold weaker GIRK activation than fingolimod-P. After oral administration of amiselimod or fingolimod at 1 mg.kg-1 , the concentration of amiselimod-P in rat heart tissue was lower than that of fingolimod-P, potentially contributing to the minimal cardiac effects of amiselimod. A telemetry study in monkeys confirmed that amiselimod did not affect heart rate or ECG parameters. In healthy human subjects, peripheral blood lymphocyte counts gradually reduced over the 21 day dosing period, with similar lymphocyte count profiles with the highest doses by day 21, and no clinically significant bradycardia observed on day 1 or during the study. CONCLUSIONS AND IMPLICATIONS: Amiselimod exhibited potent therapeutic efficacy with minimal cardiac effects at the anticipated clinical dose and is unlikely to require dose titration.

AB - Previous studies of critical care admissions have largely compared patients that have been granted or declined admission. To better understand the decision process itself, our ethnographic approach combined observation of and interviews with critical care physicians in a large English hospital. We observed 30 critical care doctors managing 71 referrals and conducted ten interviews with senior decision-makers to explore the themes raised by our observations. We analysed data using the constant comparative method. We found that the decision to move a patient to critical care was just one way in which the trajectory of critical illness could be modified. When patients were admitted to critical care, it was not always for invasive monitoring or advanced organ support, with some admitted for more general medical and/or nursing care. When patients were declined admission, they were not simply forgotten or left behind; they nevertheless underwent careful assessment and follow-up. Thus, depicting admission or refusal as a binary event is misleading. We suggest that prescriptive admission algorithms are problematic for clinicians, in that they may not take into account the complexity of clinical practice.

AB - Hyperkalemic periodic paralysis (HyperPP) is a dominantly inherited muscle disease caused by mutations in SCN4A gene encoding skeletal muscle voltage gated Nav 1.4 channels. We identified a novel Nav 1.4 mutation I692M in 14 families out of the 104 genetically identified HyperPP families in the Neuromuscular Centre Ulm and is therefore as frequent as I693T (13 families out of 14 HyperPP families) in Germany. Surprisingly, in 13 families, a known polymorphism S906T was also present. It was on the affected allele in at least 10 families compatible with a possible founder effect in central Europe. All affected members suffered from episodic weakness; myotonia was also common. Compared with I692M patients, I692M-S906T patients had longer weakness episodes, more affected muscles, CK elevation and presence of permanent weakness. Electrophysiological investigation showed that both mutants had incomplete slow inactivation and a hyperpolarizing shift of activation which contribute to membrane depolarization and weakness. Additionally, I692M-S906T significantly enhanced close-state fast inactivation compared with I692M alone, suggesting a higher proportion of inactivated I692M-S906T channels upon membrane depolarization which may facilitate the initiation of weakness episodes and therefore clinical manifestation. Our results suggest that polymorphism S906T has effects on the clinical phenotypic and electrophysiological severity of a novel borderline Nav 1.4 mutation I692M, making the borderline mutation fully penetrant. PMID- 27714769 TI - Lacosamide and sodium channel-blocking antiepileptic drug cross-titration against levetiracetam background therapy. AB - OBJECTIVE: To assess prospectively the effectiveness of lacosamide (LCM) added to levetiracetam (LEV) after down-titration of a concomitant sodium channel blocker (SCB) among patients with focal epilepsy not adequately controlled on LEV and SCB. METHODS: In this open-label trial, LCM was initiated at 100 mg/day and up titrated to 200-600 mg/day over 9 weeks; SCB down-titration started when LCM dose reached 200 mg/day. Patients remained on stable LCM/LEV doses for 12 weeks' maintenance (21-week treatment period). The primary outcome was retention rate on LCM. RESULTS: Due to recruitment challenges, fewer than the planned 300 patients participated in the trial, resulting in the trial being underpowered. Overall, 120 patients (mean age 39.7 years) started and 93 completed the trial. The most frequently used SCBs were lamotrigine (39.2%), carbamazepine (30.8%) and oxcarbazepine (27.5%). Eighty-four patients adhered to protocol and discontinued their SCB after cross-titration, but there was insufficient evidence for 36 patients. Retention rate was 73.3% (88/120) for all patients and 83.3% (70/84) for those with evidence of SCB discontinuation. Seizure freedom for patients completing maintenance was 14.0% (13/93). Discontinuation due to adverse events (6.7%) and lack of efficacy (3.3%) occurred primarily during cross-titration. Most frequently reported adverse events during treatment were dizziness (23.3%), headache (15.0%) and fatigue (8.3%). CONCLUSIONS: In patients with uncontrolled seizures on LEV/SCB, the LCM/LEV combination appeared to be effective and well tolerated. A cross-titration schedule-flexible LCM up-titration, concomitant SCB down-titration and stable background LEV-could present a feasible and practical approach to initiating LCM while minimizing pharmacodynamic interactions with a SCB.

AB - OBJECTIVE: To examine the association between different levels of childhood attention deficit hyperactivity disorder (ADHD) symptoms and sex differences in psychosocial outcomes during adolescence. METHOD: Swedish children (n = 4635) were screened for neuropsychiatric symptoms at age 9 or 12. ADHD symptoms were divided into three levels: screen-negative, screen-intermediate, and screen positive. At follow-up (age 15), parents and teenagers filled out questionnaires regarding (i) hyperactivity/inattention, (ii) peer problems, (iii) school problems, (iv) internalizing problems, (v) antisocial behaviour, (vi) alcohol misuse, and (vii) drug misuse. All outcomes were controlled for symptoms of diagnostic categories other than ADHD. RESULTS: Increasing levels of ADHD symptoms in childhood were associated with higher proportions of adolescents who displayed negative psychosocial outcomes. More girls than boys reported internalizing problems (all levels) and risky drug use (screen-intermediate and screen-positive only). More boys reported antisocial behaviour at the screen negative and screen-intermediate levels, but at the screen-positive level, similar proportions of girls and boys displayed antisocial behaviour. CONCLUSION: The findings support the view that ADHD symptoms, as well as their negative outcomes, are dimensionally distributed in the population and that adolescent girls and boys display different risk profiles. The findings confirm that ADHD symptoms are associated with higher risk of drug misuse in girls. PMID- 27714771 TI - In Vitro Functional Analyses of Infrequent Nucleotide Variants in the Lactase Enhancer Reveal Different Molecular Routes to Increased Lactase Promoter Activity and Lactase Persistence. AB - The genetic trait that allows intestinal lactase to persist into adulthood in some 35% of humans worldwide operates at the level of transcription, the effect being caused by cis-acting nucleotide changes upstream of the lactase gene (LCT). A single nucleotide substitution, -13910 C>T, the first causal variant to be identified, accounts for lactase persistence over most of Europe. Located in a region shown to have enhancer function in vitro, it causes increased activity of the LCT promoter in Caco-2 cells, and altered transcription factor binding. Three other variants in close proximity, -13907 C>G, -13915 T>C and -14010 G>C, were later shown to behave in a similar manner. Here, we study four further candidate functional variants. Two, -14009 T>G and -14011 C>T, adjacent to the well-studied -14010 G>C variant, also have a clear effect on promoter activity upregulation as assessed by transfection assays, but notably are involved in different molecular interactions. The results for the two other variants (-14028 T>C, -13779 G>C) were suggestive of function, -14028*C showing a clear change in transcription factor binding, but no obvious effect in transfections, while -13779*G showed greater effect in transfections but less on transcription factor binding. Each of the four variants arose on independent haplotypic backgrounds with different geographic distribution. PMID- 27714772 TI - Mammalian-target of rapamycin inhibition with temsirolimus in myelodysplastic syndromes (MDS) patients is associated with considerable toxicity: results of the temsirolimus pilot trial by the German MDS Study Group (D-MDS). AB - The mammalian-target of rapamycin (also termed mechanistic target of rapamycin, mTOR) pathway integrates various pro-proliferative and anti-apoptotic stimuli and is involved in regulatory T-cell (TREG) development. As these processes contribute to the pathogenesis of myelodysplastic syndromes (MDS), we hypothesized that mTOR modulation with temsirolimus (TEM) might show activity in MDS. This prospective multicentre trial enrolled lower and higher risk MDS patients, provided that they were transfusion-dependent/neutropenic or relapsed/refractory to 5-azacitidine, respectively. All patients received TEM at a weekly dose of 25 mg. Of the 9 lower- and 11 higher-risk patients included, only 4 (20%) reached the response assessment after 4 months of treatment and showed stable disease without haematological improvement. The remaining patients discontinued TEM prematurely due to adverse events. Median overall survival (OS) was not reached in the lower-risk group and 296 days in the higher-risk group. We observed a significant decline of bone marrow (BM) vascularisation (P = 0.006) but were unable to demonstrate a significant impact of TEM on the balance between TREG and pro-inflammatory T-helper-cell subsets within the peripheral blood or BM. We conclude that mTOR-modulation with TEM at a dose of 25 mg per week is accompanied by considerable toxicity and has no beneficial effects in elderly MDS patients. PMID- 27714774 TI - Similar incidence of severe acute GVHD and less severe chronic GVHD in PBSCT from unmanipulated, haploidentical donors compared with that from matched sibling donors for patients with haematological malignancies. AB - The features of graft-versus-host disease (GVHD) were compared between patients who underwent myeloablative conditioning and received a peripheral blood stem cell transplant (PBSCT) from either a haploidentical donor (HID) or a matched sibling donor (MSD) during the same period of time. The HID group included more patients with advanced disease. Both groups received the same GVHD prophylaxis with the addition of antithymoglobulin (ATG) in HID group. Higher cumulative incidences (CI) of acute GVHD grade 2-4 (35.1% vs. 13.9%, P = 0.003), similar CI of grade 3-4 (14.5% vs. 9.8%, P = 0.595), less 3-year CI of extensive chronic GVHD (17.1% vs. 41.5%, P = 0.017) and less severe chronic GVHD (5.8% vs. 21.2%, P = 0.049) occurred in the HID group compared with the MSD group. There was no difference in the sites of the involved organs between these two groups. Higher 3 year CI of non-relapse mortality (24.0% vs. 10.2%, P = 0.014), relapse (39.0% vs. 22.6%, P = 0.032) and inferior disease-free survival (45.7% vs. 78.9%, P = 0.000) were recorded in the HID cohort compared with the MSD group. More HID patients had Karnofsky scores above 90 than those in MSD group (P = 0.016). In conclusion, ATG plays a key role in the unmanipulated HID PBSCT protocol, producing better quality of life in survivors. PMID- 27714773 TI - Histamine H4 receptor agonist-induced relief from painful peripheral neuropathy is mediated by inhibition of spinal neuroinflammation and oxidative stress. AB - BACKGROUND AND PURPOSE: Neuropathic pain is under-treated, with a detrimental effect on quality of life, partly because of low treatment efficacy, but also because pathophysiological mechanisms are not fully elucidated. To clarify the pathobiology of neuropathic pain, we studied the contribution of neuroinflammation and oxidative stress in a model of peripheral neuropathy. We also assessed an innovative treatment for neuropathic pain by investigating the effects of histamine H4 receptor ligands in this model. EXPERIMENTAL APPROACH: A peripheral mononeuropathy was induced in mice, by spared nerve injury (SNI). Neuroinflammation and oxidative stress parameters were evaluated by spectrophotometry. The mechanical (von Frey test) and thermal (plantar test) nociceptive thresholds were evaluated. KEY RESULTS: SNI mice showed increased expression of the pro-inflammatory cytokines IL-1beta and TNF-alpha, decreased antioxidant enzyme Mn-containing SOD (MnSOD), increased levels of 8-hydroxy-2' deoxyguanosine (8-OHdG), an indicator of oxidative DNA damage, and of PARP, nuclear enzyme activated upon DNA damage. Intrathecal administration of VUF 8430 (H4 receptor agonist) reversed the mechanical and thermal allodynia and was associated with decreased expression of IL-1beta, TNF-alpha, 8-OHdG and PARP and with restoration of MnSOD activity in the spinal cord and sciatic nerve. These effects were prevented by JNJ 10191584 (H4 receptor antagonist). CONCLUSION AND IMPLICATIONS: In the SNI mouse model of neuropathic pain, neuronal H4 receptor stimulation counteracts hyperalgesia and reduces neuroinflammation and oxidative stress in the spinal cord and sciatic nerve. Targeting both oxidative stress and pro-neuroinflammatory pathways through H4 receptor-mediated mechanisms could have promising therapeutic potential for neuropathic pain management. PMID- 27714775 TI - Detection of fetal abnormalities by second-trimester ultrasound screening in a non-selected population. AB - INTRODUCTION: This study assessed the sensitivity of routine ultrasound examination for the detection of abnormal chromosomes and structural malformations in fetuses in the second trimester in a non-selected population. MATERIAL AND METHODS: Prenatal diagnoses of fetal abnormalities in 10 414 fetuses and newborns were reviewed and compared with all postnatal diagnoses of congenital abnormalities between 2006 and 2013. RESULTS: Overall, 243 fetuses and newborns had confirmed congenital abnormalities, with a prevalence of 2.3%. Of these fetuses and newborns, 23% (56/243) had chromosomal abnormalities (overall prevalence 0.5%), and 77% (187/243) had normal chromosomes with either major (44%; 82/187) or minor (56%; 105/187) structural malformations (overall prevalence 1.8%). One hundred and seven abnormalities were detected prenatally, yielding a total sensitivity for prenatal detection of fetal abnormalities of 44.0% (107/243; 95% CI 37.8-50.2), with specificity of 99.9%, a positive predictive value of 94.7%, and a negative predictive value of 98.7%. The sensitivity for prenatal detection before 22 weeks of gestation was 40.3% (98/243; 95% CI 34.1-46.5). The prenatal detection rate of chromosomal abnormalities was 60.7% (34/56) and, for structural malformations, was 39.0% (73/187). CONCLUSIONS: In a routine clinical setting at a county hospital with a non-selected population, half of the major structural malformations in chromosomally normal fetuses are detected by routine ultrasound examination in the second trimester. Chromosomal abnormalities have the highest probability for prenatal detection; the majority are diagnosed by amniocentesis before the routine ultrasound examination in high-risk women. PMID- 27714777 TI - Multiprofessional evaluation in clinical practice: establishing a core set of outcome measures for children with cerebral palsy. AB - AIM: To develop a national consensus on outcome measures that define functional ability in children with cerebral palsy (CP) according to the International Classification of Functioning, Disability and Health (ICF) framework. METHOD: The project started in 2008 in neuropaediatric units of two university hospitals and one outpatient clinic. Each professional group selected representatives to be knowledge brokers for their own specialty. Based on the evidence, expert opinion, and the ICF framework, multiprofessional teams selected the most valid measures used in clinical practice (2009-2010). Data from 269 children with CP were analysed, classified by the Gross Motor Function Classification System, Manual Ability Classification System, and Communication Function Classification System, and evaluated. RESULTS: The process aimed at improving and unifying clinical practice in Finland through a national consensus on the core set of measures. The selected measures were presented by professional groups, and consensus was reached on the recommended core set of measures to be used in all hospitals treating children with CP in Finland. INTERPRETATION: A national consensus on relevant and feasible measures is essential for identifying differences in the effectiveness of local practices, and for conducting multisite intervention studies. This project showed that multiprofessional rehabilitation practices can be improved through respect for and inclusion of everyone involved. PMID- 27714776 TI - Trastuzumab cardiotoxicity: from clinical trials to experimental studies. AB - : Epidermal growth factor receptor-2 (HER-2) is overexpressed in 20 to 25% of human breast cancers, which is associated with aggressive tumour growth and poor prognosis. Trastuzumab (Herceptin(r)) is a humanized monoclonal antibody directed against HER-2, the first highly selective form of therapy targeting HER-2 overexpressing tumours. Although initial trials indicated high efficacy and a favourable safety profile of the drug, the first large, randomized trial prompted a retrospective analysis of cardiac dysfunction in earlier trials utilizing trastuzumab. There has been ongoing debate on the cardiac safety of trastuzumab ever since, initiating numerous clinical and preclinical investigations to better understand the background of trastuzumab cardiotoxicity and evaluate its effects on patient morbidity. Here, we have given a comprehensive overview of our current knowledge on the cardiotoxicity of trastuzumab, primarily focusing on data from clinical trials and highlighting the main molecular mechanisms proposed.

PMID- 27714778 TI - Meta-analysis of the use of surgical sealants for suture-hole bleeding in arterial anastomoses. AB - BACKGROUND: Suture-hole bleeding in arterial anastomoses prolongs operating time and increases blood loss, particularly with the use of prosthetic grafts. Surgical sealants (such as fibrin) may be used as haemostatic adjuncts in vascular surgery. This is a systematic review and meta-analysis of published studies that investigated the utility of surgical sealants in arterial-to prosthetic graft anastomoses. METHODS: A systematic review was undertaken of papers published until January 2015 on Embase, MEDLINE, PubMed, PubMed Central and Cochrane databases that analysed the use of surgical sealants as haemostatic adjuncts after arterial anastomoses. RCTs were included, with study endpoints of time to haemostasis or haemostasis at 5 min. Secondary outcomes included treatment failure, mean difference in estimated blood loss and duration of surgery. Sensitivity and subgroup analyses were performed, as well as funnel plot analysis for publication bias. RESULTS: A total of 2513 citations were reviewed; 19 RCTs comprising 1560 patients were ultimately included in the analysis. The majority of studies compared fibrin sealant with control haemostatic measures. Pooled analysis suggested that surgical sealants reduced the time to haemostasis (mean difference 243.26 (95 per cent c.i. 183.99 to 302.53) s; P < 0.001), improved haemostasis at 5 min (odds ratio 4.50, 95 per cent c.i. 2.59 to 7.81; P < 0.001), and were associated with less treatment failure, blood loss and shorter duration of surgery. CONCLUSION: Surgical sealants appear to reduce suture-hole bleeding significantly in vascular prosthetic graft anastomoses compared with standard haemostatic measures. PMID- 27714779 TI - Pharmacological mechanisms underlying the cardiovascular effects of the "bath salt" constituent 3,4-methylenedioxypyrovalerone (MDPV). AB - BACKGROUND AND PURPOSE: 3,4-Methylenedioxypyrovalerone (MDPV) is a synthetic cathinone with stimulatory cardiovascular effects that can lead to serious medical complications. Here, we examined the pharmacological mechanisms underlying these cardiovascular actions of MDPV in conscious rats. EXPERIMENTAL APPROACH: Male Sprague-Dawley rats had telemetry transmitters surgically implanted for the measurement of BP and heart rate (HR). On test days, rats were placed individually in standard isolation cubicles. Following drug treatment, cardiovascular parameters were monitored for 3 h sessions. KEY RESULTS: Racemic MDPV (0.3-3.0 mg.kg-1 ) increased BP and HR in a dose-dependent manner. The S(+) enantiomer (0.3-3.0 mg.kg-1 ) of MDPV produced similar effects, while the R(-) enantiomer (0.3-3.0 mg.kg-1 ) had no effects. Neither of the hydroxylated phase I metabolites of MDPV altered cardiovascular parameters significantly from baseline. Pretreatment with the ganglionic blocker chlorisondamine (1 and 3 mg.kg 1 ) antagonized the increases in BP and HR produced by 1 mg.kg-1 MDPV. The alpha1 -adrenoceptor antagonist prazosin (0.3 mg.kg-1 ) attenuated the increase in BP following MDPV, while the beta-adrenoceptor antagonists propranolol (1 mg.kg-1 ) and atenolol (1 and 3 mg.kg-1 ) attenuated the HR increases. CONCLUSIONS AND IMPLICATIONS: The S(+) enantiomer appeared to mediate the cardiovascular effects of MDPV, while the metabolites of MDPV did not alter BP or HR significantly; MDPV increased BP and HR through activation of central sympathetic outflow. Mixed action alpha/beta-adrenoceptor antagonists may be useful as treatments in counteracting the adverse cardiovascular effects of MDPV.

PMID- 27714782 TI - N-terminal polar amino acids of the C2 insert of nonmuscle myosin II-C2 regulate its functional properties. AB - In this study, we investigated the regions in the alternatively spliced C2 insert of nonmuscle myosin (NM) II-C conferring unique functional properties to the protein. We used constructs carrying deletions within different regions of C2 in neuronal cells; namely, the polar N terminus, the proline/serine-rich middle, and the nonpolar C terminus. We compared the wild-type NM II-C2 and deletion mutants with respect to ATPase activity, coassembly with NM II-B, regulation by myosin light-chain kinase (MLCK), and solubility, to determine the C2 region(s) involved in these processes. In addition, we examined the ability of the mutants to rescue the neurite-shortening phenotype upon NM II-C2 knockdown in Neuro-2a cells. Our data highlight the importance of the polar N terminus in NM II-C2 function. PMID- 27714781 TI - Effect of topical imiquimod as primary treatment for lentigo maligna: the LIMIT-1 study. AB - BACKGROUND: Topical imiquimod is sometimes used for lentigo maligna (LM) in situ melanoma instead of surgery, but frequency of cure is uncertain. Pathological complete regression (pCR) is a logical surrogate marker for cure after imiquimod, although residual LM and atypical melanocytic hyperplasia may not be reliably distinguished. A trial comparing imiquimod vs. surgery might be justified by a high imiquimod pCR rate. OBJECTIVES: Primary: to estimate the pCR rate for LM following imiquimod. Secondary: to assess the accuracy of prediction of pCR, using clinical complete regression (cCR) plus negative post-treatment biopsies, tolerability, resource use, patients' preferences and induced melanoma immunity. METHODS: This was a single-arm phase II trial of 60 imiquimod applications over 12 weeks for LM then radical resection. A pCR rate >= 25 out of 33 would reliably discriminate between pCR rates < 60% and >= 85%. Clinical response was assessed and biopsies taken after imiquimod. Patients recorded adverse events in diaries. Patient preference was measured after surgery using a standard gamble tool. RESULTS: The pCR rate was 10 of 27 (37%, 95% confidence interval 19-58%). The rate of cCR plus negative biopsies was 12 of 28, of whom seven of 11 had pCR on subsequent surgery. The median dose intensity was 86.7%. Of the 16 surveyed patients, eight preferred primary imiquimod over surgery if the cure rate for imiquimod was 80%, and four of 16 if it was <= 40%. CONCLUSIONS: The pCR rate was insufficient to justify phase III investigation of imiquimod vs. SURGERY: Clinical complete response and negative targeted biopsies left uncertainty regarding pathological clearance. Some patients would trade less aggressive treatment of LM against efficacy. PMID- 27714783 TI - Mate guarding and frequent copulation in birds: A meta-analysis of their relationship to paternity and male phenotype. AB - In many birds, males are presumed to protect their paternity by closely guarding their mate or copulating frequently with her. Both these costly behaviors are assumed to reduce the risk and/or intensity of sperm competition. However, despite many studies on avian extra-pair paternity, it remains unclear how strongly these behaviors are related to fitness and other key life-history traits. Here, we conduct meta-analyses to address two questions. First, are mate guarding and/or frequent copulation positively correlated with a male's share of paternity at his nest? We find a significant positive correlation between both presumed paternity protection behaviors and paternity share. The relationship is, however, weak (r = 0.08-0.23). This is perhaps unsurprising if the risk of partner infidelity, hence the need to protect paternity, varies among males. For example, more attractive males might have less need to protect their paternity. Second, do males with higher indices of so-called male "quality" (phenotypic measures, usually subjectively defined by researchers as predictors of male attractiveness) exhibit lower levels of paternity protection behavior? We find a negative correlation between male quality and paternity protection. This finding might partly explain the weak relationship between paternity protection and paternity, although we discuss other, nonmutually exclusive possibilities. PMID- 27714785 TI - Behavioral development in embryonic and early juvenile cuttlefish (Sepia officinalis). AB - Though a mollusc, the cuttlefish Sepia officinalis possesses a sophisticated brain, advanced sensory systems, and a large behavioral repertoire. Cuttlefish provide a unique perspective on animal behavior due to their phylogenic distance from more traditional (vertebrate) models. S. officinalis is well-suited to addressing questions of behavioral ontogeny. As embryos, they can perceive and learn from their environment and experience no direct parental care. A marked progression in learning and behavior is observed during late embryonic and early juvenile development. This improvement is concomitant with expansion and maturation of the vertical lobe, the cephalopod analog of the mammalian hippocampus. This review synthesizes existing knowledge regarding embryonic and juvenile development in this species in an effort to better understand cuttlefish behavior and animal behavior in general. It will serve as a guide to future researchers and encourage greater awareness of the utility of this species to behavioral science. PMID- 27714784 TI - Platelets Toll-like receptor-4 in Crohns disease. AB - BACKGROUND: Platelets are activated in Crohn's disease (CD) and interplay with leukocytes. Engagement of Toll-like receptor-4 (TLR-4), which is expressed in human platelets, may be involved in crosstalks between platelets and leukocytes leading to their mutual activation for host defense. MATERIALS AND METHODS: Human neutrophil peptides (HNPs), lipoprotein binding peptides, and sCD14 were determined by enzyme-linked immunosorbent assays in 42 patients with active CD, in 43 patients with CD in remission, and in 30 healthy individuals. Neutrophil platelet aggregates and binding of the TLR-4 monoclonal antibody to platelets were determined by flow cytometry. RESULTS: Levels of HNPs were higher in patients with CD than in controls (P = 0.0003 vs. active CD and P = 0.01 vs. CD in remission). Likewise, neutrophils with adhering platelets were higher in patients with active CD than in controls (P = 0.004). Binding of the TLR-4 antibody in patients with active CD was similar to that in controls, while patients in remission had significantly higher binding capacities (P = 0.59 and P = 0.003). Incubation of plasma from patients with active disease or patients in remission with platelets from healthy controls confirmed lower binding of the TLR 4 antibody in the presence of plasma from active diseased patients compared to controls (P = 0.039), possibly due to high levels of lipopolysaccharides, as suggested by high levels of sCD14 and lipoprotein binding protein. CONCLUSION: Our study indicates involvement of platelet TLR-4 in enhancing the secretion of antimicrobial peptides from neutrophils. While platelet aggregation can be due to a variety of mechanisms in inflammatory disease, the mutual activation of platelets and neutrophils may augment host defense. PMID- 27714786 TI - Transfer Frequency as a Measure of Hospital Capability and Regionalization. AB - OBJECTIVE: To provide metrics for quantifying the capability of hospitals and the degree of care regionalization. DATA SOURCE: Administrative database covering more than 10 million hospital encounters during a 3-year period (2012-2014) in Massachusetts. PRINCIPAL FINDINGS: We calculated the condition-specific probabilities of transfer for all acute care hospitals in Massachusetts and devised two new metrics, the Hospital Capability Index (HCI) and the Regionalization Index (RI), for analyzing hospital systems. The HCI had face validity, accurately differentiating academic, teaching, and community hospitals of varying size. Individual hospital capabilities were clearly revealed in "fingerprints" of their condition-specific transfer behavior. The RI also performed well, with those of specific conditions successfully quantifying the concentration of care arising from regulatory and public health activity. The median RI of all conditions within the Massachusetts health care system was 0.21 (IQR, 0.13-0.36), with a long tail of conditions that were very highly regionalized. Application of the HCI and RI metrics together across the entire state identified the degree of interdependence among its hospitals. CONCLUSIONS: Condition-specific transfer activity, as captured in the HCI and RI, provides quantitative measures of hospital capability and regionalization of care. PMID- 27714787 TI - Integrins and heparan sulfate proteoglycans on hepatic stellate cells (HSC) are novel receptors for HSC-derived exosomes. AB - Exosomes mediate intercellular microRNA delivery between hepatic stellate cells (HSC), the principal fibrosis-producing cells in the liver. The purpose of this study was to identify receptors on HSC for HSC-derived exosomes, which bind to HSC rather than to hepatocytes. Our findings indicate that exosome binding to HSC is blocked by treating HSC with RGD, EDTA, integrin alphav or beta1 siRNAs, integrin alphavbeta3 or alpha5beta1 neutralizing antibodies, heparin, or sodium chlorate. Furthermore, exosome cargo delivery and exosome-regulated functions in HSC, including expression of fibrosis- or activation-associated genes and/or miR 214 target gene regulation, are dependent on cellular integrin alphavbeta3, integrin alpha5beta1, or heparan sulfate proteolgycans (HSPG). Thus, integrins and HSPG mediate the binding of HSC-derived exosomes to HSC as well as the delivery and intracellular action of the exosomal payload. PMID- 27714788 TI - A feasibility trial of an Internet-delivered and transdiagnostic cognitive behavioral therapy treatment program for anxiety, depression, and disability among adults with epilepsy. AB - OBJECTIVE: Anxiety and depression are highly prevalent in people with epilepsy (PWE) and contribute to increased disability. Unfortunately, there are numerous barriers (e.g., cost, distance, and stigma) and service gaps (e.g., lack of services and trained clinicians) that prevent many PWE from accessing traditional face-to-face psychological services. The aim of the present study was to examine the feasibility of a new transdiagnostic Internet-delivered cognitive behavioral therapy (iCBT) program, the Chronic Conditions Course, to simultaneously treat symptoms of anxiety, depression, and disability. METHODS: A single-group feasibility open trial was employed involving 27 adults with epilepsy. The program comprises five online lessons delivered over 8 weeks and is provided with weekly contact from a mental health professional via e-mail and telephone. RESULTS: High treatment completion rates and levels of satisfaction were reported. Evidence of significant improvements in our primary outcomes (within group Cohen's d [d]; average [avg.] reductions) of anxiety (d >= 1.28; avg. reduction >= 54%), depression (d >= 1.24; avg. reduction >= 54%), epilepsy specific depression (d >= 0.95; avg. reduction >= 35%), and disability (d >= 0.62; avg. reduction >= 33%) were observed at posttreatment, which were sustained at or further improved to 3-month follow-up. On our secondary outcomes there were significant improvements for life satisfaction (d >= 0.70; avg. improvement >= 26%) but not for perceived cognitive difficulties (d >= 0.48; avg. reduction >= 15%). Highlighting the potential of the approach, relatively little clinician time was required per participant (mean 80.62 min, standard deviation [SD] 54.78), and the trial involved a broad range of geographically dispersed patients. SIGNIFICANCE: The findings of the current study support the feasibility and potential of transdiagnostic Internet-delivered treatments for adults with epilepsy. Further large-scale controlled trials are warranted. PMID- 27714789 TI - Substrate profiling of Zika virus NS2B-NS3 protease. AB - Zika virus (ZIKV), isolated from macaques in Uganda in 1947, was not considered to be a dangerous human pathogen. However, this view has recently changed as ZIKV infections are now associated with serious pathological disorders including microcephaly and Guillain-Barre syndrome. Similar to other viruses in the Flaviviridae family, ZIKV expresses the serine protease NS3 which is responsible for viral protein processing and replication. Herein, we report the expression of an active NS3pro domain fused with the NS2B cofactor (NS2BLN NS3pro ) in a prokaryotic expression system and profile its specificity for synthesized FRET type substrate libraries. Our findings pave way for screening potential intracellular substrates of NS3 and for developing specific inhibitors of this ZIKV protease. PMID- 27714792 TI - Quality and safety in adult epilepsy monitoring units: A systematic review and meta-analysis. AB - OBJECTIVE: The epilepsy monitoring unit (EMU) is a valuable resource for optimizing management of persons with epilepsy, but may place patients at risk for adverse events due to withdrawal of treatment and induction of symptoms. The purpose of this study was to synthesize data on the safety and quality of care in EMUs to inform the development of quality indicators for EMUs. METHODS: A systematic review was conducted according to the Preferred Reporting and Items for Systematic Review and Meta-Analysis (PRISMA) statement. The search strategy, which included broad search terms and synonyms pertaining to the EMU, was run in six medical databases and included conference proceedings. Data abstracted included patient and EMU demographics and quality and safety variables. Study quality was evaluated using a modified 15-item Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. Descriptive statistics and meta-analyses were used to describe and synthesize the evidence. RESULTS: The search yielded 7,601 references, of which 604 were reviewed in full text. One hundred thirty-five studies were included. The quality and safety data came from 181,823 patients and reported on 34 different quality and safety variables. Included studies commonly reported the number of patients (108 studies; median number patients, 171.5), age (49 studies; mean age 35.7 years old), and the reason for admission (34 studies). The most common quality and safety data reported were the utility of the EMU admission (38 studies). Thirty-three studies (24.4%) reported on adverse events, and yielded a pooled proportion of adverse events of 7% (95% confidence interval [CI] 5-9%). The mean quality score was 73.3% (standard deviation [SD] 17.2). SIGNIFICANCE: This study demonstrates that there is a great deal of variation in the reporting of quality and safety measures and in the quality and safety in EMUs. Study quality also varied considerably from one study to the next. These findings highlight the need to develop evidence-based, consensus-driven quality indicators for EMUs. PMID- 27714791 TI - Misclassification Risk of Tier-Based Physician Quality Performance Systems. AB - OBJECTIVE: There is increasing interest in identifying high-quality physicians, such as whether physicians perform above or below a threshold level. To evaluate whether current methods accurately distinguish above- versus below-threshold physicians, we estimate misclassification rates for two-category identification systems. DATA SOURCES: Claims data for Medicare fee-for-service beneficiaries residing in Florida or New York in 2010. STUDY DESIGN: Estimate colorectal cancer, glaucoma, and diabetes quality scores for 23,085 physicians. Use a beta binomial model to estimate physician score reliabilities. Compute the proportion of physicians whose performance tier would be misclassified under three scoring systems. PRINCIPAL FINDINGS: In the three scoring systems, misclassification ranges were 8.6-25.7 percent, 6.4-22.8 percent, and 4.5-21.7%. True positive rate ranges were 72.9-97.0 percent, 83.4-100.0 percent, and 34.7-88.2 percent. True negative rate ranges were 68.5-91.6 percent, 10.5-92.4 percent, and 81.1-99.9 percent. Positive predictive value ranges were 70.5-91.6 percent, 77.0-97.3 percent, and 55.2-99.1 percent. CONCLUSIONS: Current methods for profiling physicians on quality may produce misleading results, as the number of eligible events is typically small. Misclassification is a policy-relevant measure of the potential impact of tiering on providers, payers, and patients. Quantifying misclassification rates should inform the construction of high-performance networks and quality improvement initiatives. PMID- 27714793 TI - Genetic drift and mutational hazard in the evolution of salamander genomic gigantism. AB - Salamanders have the largest nuclear genomes among tetrapods and, excepting lungfishes, among vertebrates as a whole. Lynch and Conery (2003) have proposed the mutational-hazard hypothesis to explain variation in genome size and complexity. Under this hypothesis, noncoding DNA imposes a selective cost by increasing the target for degenerative mutations (i.e., the mutational hazard). Expansion of noncoding DNA, and thus genome size, is driven by increased levels of genetic drift and/or decreased mutation rates; the former determines the efficiency with which purifying selection can remove excess DNA, whereas the latter determines the level of mutational hazard. Here, we test the hypothesis that salamanders have experienced stronger long-term, persistent genetic drift than frogs, a related clade with more typically sized vertebrate genomes. To test this hypothesis, we compared dN/dS and Kr/Kc values of protein-coding genes between these clades. Our results do not support this hypothesis; we find that salamanders have not experienced stronger genetic drift than frogs. Additionally, we find evidence consistent with a lower nucleotide substitution rate in salamanders. This result, along with previous work showing lower rates of small deletion and ectopic recombination in salamanders, suggests that a lower mutational hazard may contribute to genomic gigantism in this clade. PMID- 27714790 TI - TeloPCR-seq: a high-throughput sequencing approach for telomeres. AB - We have developed a high-throughput sequencing approach that enables us to determine terminal telomere sequences from tens of thousands of individual Schizosaccharomyces pombe telomeres. This method provides unprecedented coverage of telomeric sequence complexity in fission yeast. S. pombe telomeres are composed of modular degenerate repeats that can be explained by variation in usage of the TER1 RNA template during reverse transcription. Taking advantage of this deep sequencing approach, we find that 'like' repeat modules are highly correlated within individual telomeres. Moreover, repeat module preference varies with telomere length, suggesting that existing repeats promote the incorporation of like repeats and/or that specific conformations of the telomerase holoenzyme efficiently and/or processively add repeats of like nature. After the loss of telomerase activity, this sequencing and analysis pipeline defines a population of telomeres with altered sequence content. This approach will be adaptable to study telomeric repeats in other organisms and also to interrogate repetitive sequences throughout the genome that are inaccessible to other sequencing methods. PMID- 27714794 TI - Pubertal pair-housing facilitates adult sexual behavior in male rats. AB - This study examined the effects of pubertal testosterone (T) and social housing manipulations on male sexual behavior in adult rats. Prepubertal rats were castrated at 21 days of age (P21) and implanted with either blank or T-releasing pellets. At the onset of puberty, P28, half the rats in each treatment group were either single- or pair-housed with a male of the same hormone condition through P56, at which time pellets were removed and all rats were single-housed. In adulthood (P84), all rats received T replacement and were tested for sexual behavior. Rats pair-housed during adolescence showed more sexual behavior and greater improvement of sexual performance over repeated tests than single-housed rats, regardless of pubertal T status. Pubertal T, however, did facilitate the frequency of anogenital investigation. Thus, in male rats, social interactions during adolescence are more important than exposure to pubertal T in enhancing adult sexual behavior. PMID- 27714795 TI - Experimental insights on the function of ancillary pollen and stigma polymorphisms in plants with heteromorphic incompatibility. AB - Most heterostylous plants possess a reciprocal arrangement of stigmas and anthers (reciprocal herkogamy), heteromorphic self-incompatibility, and ancillary polymorphisms of pollen and stigmas. The topographical complementarity hypothesis proposes that ancillary polymorphisms function in the rejection of incompatible pollen thus promoting disassortative pollination. Here, we test this hypothesis by investigating patterns of pollen transfer and capture in populations of dimorphic Armeria maritima and A. pubigera and distylous Limonium vulgare (Plumbaginaceae), and by studying pollen adherence and germination patterns in A. maritima following controlled hand-pollinations. Armeria lacks reciprocal herkogamy allowing the evaluation of the extent to which ancillary polymorphisms affect the composition of pollen loads. We compared the amounts of compatible and incompatible pollen on stigmas in natural populations and calculated the proficiencies of pollen transfer for each mating type. We detected disassortative pollination in each species, and mating types did not differ in compatible pollen capture, although cob stigmas captured more incompatible pollen. Controlled hand pollinations revealed the failure of incompatible pollen to adhere and germinate on stigmas. Our results provided evidence that, while structural in nature, pollen-stigma dimorphisms are tightly associated with heteromorphic incompatibility and likely function to promote disassortative pollination, especially in the absence of reciprocal herkogamy. PMID- 27714797 TI - Structural insights into the interaction of human p97 N-terminal domain and SHP motif in Derlin-1 rhomboid pseudoprotease. AB - The interaction of the rhomboid pseudoprotease Derlin-1 and p97 is crucial for the retrotranslocation of polyubiquitinated substrates in the endoplasmic reticulum-associated degradation pathway. We report a 2.25 A resolution structure of the p97 N-terminal domain (p97N) in complex with the Derlin-1 SHP motif. Remarkably, the SHP motif adopts a short, antiparallel beta-strand that interacts with the beta-sheet of p97N-a site distinct from that to which most p97 adaptor proteins bind. Mutational and biochemical analyses contributed to defining the specific interaction, demonstrating the importance of a highly conserved binding pocket on p97N and a signature motif on SHP. Our findings may also provide insights into the interactions between other SHP-containing proteins and p97N. PMID- 27714796 TI - Genomic imprinting, disrupted placental expression, and speciation. AB - The importance of regulatory incompatibilities to the early stages of speciation remains unclear. Hybrid mammals often show extreme parent-of-origin growth effects that are thought to be a consequence of disrupted genetic imprinting (parent-specific epigenetic gene silencing) during early development. Here, we test the long-standing hypothesis that abnormal hybrid growth reflects disrupted gene expression due to loss of imprinting (LOI) in hybrid placentas, resulting in dosage imbalances between paternal growth factors and maternal growth repressors. We analyzed placental gene expression in reciprocal dwarf hamster hybrids that show extreme parent-of-origin growth effects relative to their parental species. In massively enlarged hybrid placentas, we observed both extensive transgressive expression of growth-related genes and biallelic expression of many genes that were paternally silenced in normal sized hybrids. However, the apparent widespread disruption of paternal silencing was coupled with reduced gene expression levels overall. These patterns are contrary to the predictions of the LOI model and indicate that hybrid misexpression of dosage-sensitive genes is caused by other regulatory mechanisms in this system. Collectively, our results support a central role for disrupted gene expression and imprinting in the evolution of mammalian hybrid inviability, but call into question the generality of the widely invoked LOI model. PMID- 27714798 TI - The "when" and the "where" of single-trial allocentric spatial memory performance in young children: Insights into the development of episodic memory. AB - Allocentric spatial memory, "where" with respect to the surrounding environment, is one of the three fundamental components of episodic memory: what, where, when. Whereas basic allocentric spatial memory abilities are reliably observed in children after 2 years of age, coinciding with the offset of infantile amnesia, the resolution of allocentric spatial memory acquired over repeated trials improves from 2 to 4 years of age. Here, we first show that single-trial allocentric spatial memory performance improves in children from 3.5 to 7 years of age, during the typical period of childhood amnesia. Second, we show that large individual variation exists in children's performance at this age. Third, and most importantly, we show that improvements in single-trial allocentric spatial memory performance are due to an increasing ability to spatially and temporally separate locations and events. Such improvements in spatial and temporal processing abilities may contribute to the gradual offset of childhood amnesia. PMID- 27714799 TI - Can a More User-Friendly Medicare Plan Finder Improve Consumers' Selection of Medicare Plans? AB - OBJECTIVE: To evaluate the efficacy for consumers of two potential enhancements to the Medicare Plan Finder (MPF)-a simplified data display and a "quick links" home page designed to match the specific tasks that users seek to accomplish on the MPF. DATA SOURCES/STUDY SETTING: Participants (N = 641) were seniors and adult caregivers of seniors who were recruited from a national online panel. Participants browsed a simulated version of the MPF, made a hypothetical plan choice, and reported on their experience. STUDY DESIGN: Participants were randomly assigned to one of eight conditions in a fully factorial design: 2 home pages (quick links, current MPF home page) * 2 data displays (simplified, current MPF display) * 2 plan types (stand-alone prescription drug plan [PDP], Medicare Advantage plan with prescription drug coverage [MA-PD]). PRINCIPAL FINDINGS: The quick links page resulted in more favorable perceptions of the MPF, improved users' understanding of the information, and increased the probability of choosing the objectively best plan. The simplified data display resulted in a more favorable evaluation of the website, better comprehension of the displayed information, and, among those choosing a PDP only, an increased probability of choosing the best plan. CONCLUSIONS: Design enhancements could markedly improve average website users' understanding, ability to use, and experience of using the MPF. PMID- 27714801 TI - An updated structural classification of substrate-binding proteins. AB - Substrate-binding proteins (SBPs) play an important role in solute uptake and signal transduction. In 2010, Berntsson et al. classified the 114 organism specific SBP structures available at that time and defined six protein clusters, based on their structural similarity. Since then, the number of unique SBP structures has increased almost fivefold, whereas the number of protein entries in the Protein Data Bank (PDB) nearly doubled. On the basis of the much larger dataset, we now subclassify the SBPs within the original clusters. Moreover, we propose a 7th cluster based on a small group of SBPs with structural features significantly different from those observed in the other proteins. PMID- 27714800 TI - Sustained User Engagement in Health Information Technology: The Long Road from Implementation to System Optimization of Computerized Physician Order Entry and Clinical Decision Support Systems for Prescribing in Hospitals in England. AB - OBJECTIVE: To explore and understand approaches to user engagement through investigating the range of ways in which health care workers and organizations accommodated the introduction of computerized physician order entry (CPOE) and computerized decision support (CDS) for hospital prescribing. STUDY SETTING: Six hospitals in England, United Kingdom. STUDY DESIGN: Qualitative case study. DATA COLLECTION: We undertook qualitative semi-structured interviews, non-participant observations of meetings and system use, and collected organizational documents over three time periods from six hospitals. Thematic analysis was initially undertaken within individual cases, followed by cross-case comparisons. FINDINGS: We conducted 173 interviews, conducted 24 observations, and collected 17 documents between 2011 and 2015. We found that perceived individual and safety benefits among different user groups tended to facilitate engagement in some, while other less engaged groups developed resistance and unsanctioned workarounds if systems were perceived to be inadequate. We identified both the opportunity and need for sustained engagement across user groups around system enhancement (e.g., through customizing software) and the development of user competencies and effective use. CONCLUSIONS: There is an urgent need to move away from an episodic view of engagement focused on the preimplementation phase, to more continuous holistic attempts to engage with and respond to end-users. PMID- 27714802 TI - Persistent and Repetitive Visual Disturbances in Migraine: A Review. AB - Visual disturbances in migraineurs, such as visual aura, are typically episodic, that is, associated with the headache attack, and overlaid by head pain and other symptoms that impact the patient. In some patients, however, visual symptoms are dominant due to frequency (migraine aura status), duration (persistent migraine aura and other persistent positive visual phenomena), or complexity (visual snow syndrome). These syndromes are more rare and challenging to classify in clinical practice resulting in a lack of systematic studies on pathophysiology and treatment. We aim at describing clinical features and pathophysiological concepts of typical migraine aura with a focus on cortical spreading depression and differentiation from non-typical migraine aura. Additionally, we discuss nomenclature and the specifics of migraine aura status, persistent migraine aura, persistent positive visual phenomena, visual snow, and other migrainous visual disturbances. The term migraine with prolonged aura might be a useful bridge between typical aura and persistent aura. Further studies would be necessary to assess whether a return of the classification category eventually helps diagnosing or treating patients more effectively. A practical approach is presented to help the treating physician to assign the correct diagnosis and to choose a medication for treatment that has been successful in case reports of these rare but disabling conditions. PMID- 27714803 TI - Production and characterization of cowpea protein hydrolysate with optimum nitrogen solubility by enzymatic hydrolysis using pepsin. AB - BACKGROUND: Cowpea is a source of low-cost and good nutritional quality protein for utilization in food formulations in replacement of animal proteins. Therefore it is necessary that cowpea protein exhibits good functionality, particularly protein solubility which affects the other functional properties. The objective of this study was to produce cowpea protein hydrolysate exhibiting optimum solubility by the adequate combination of hydrolysis parameters, namely time, solid/liquid ratio (SLR) and enzyme/substrate ratio (ESR), and to determine its functional properties and molecular characteristics. RESULTS: A Box-Behnken experimental design was used for the experiments, and a second-order polynomial to model the effects of hydrolysis time, SLR and ESR on the degree of hydrolysis and nitrogen solubility index. The optimum hydrolysis conditions of time 208.61 min, SLR 1/15 (w/w) and ESR 2.25% (w/w) yielded a nitrogen solubility of 75.71%. Protein breakdown and the peptide profile following enzymatic hydrolysis were evaluated by sodium dodecyl sulfate polyacrylamide gel electrophoresis and size exclusion chromatography. Cowpea protein hydrolysate showed higher oil absorption capacity, emulsifying activity and foaming ability compared with the concentrate. CONCLUSION: The solubility of cowpea protein hydrolysate was adequately optimized by response surface methodology, and the hydrolysate showed adequate functionality for use in food.

AB - In this review, we examine the so-called OB-fold, a tRNA-binding domain homologous to the bacterial tRNA-binding protein Trbp111. We highlight the ability of OB-fold homologs to bind tRNA species and summarize their distribution in evolution. Nature has capitalized on the advantageous effects acquired when an OB-fold domain binds to tRNA by evolutionarily selecting this domain for fusion to different enzymes. Here, we review our current understanding of how the complexity of OB-fold-containing proteins and enzymes developed to expand their functions, especially in unicellular, pathogenic eukaryotes. PMID- 27714806 TI - miR-296 inhibits proliferation and induces apoptosis by targeting FGFR1 in human hepatocellular carcinoma. AB - MiR-296 was previously reported to be underexpressed in hepatocellular carcinoma (HCC). However, the clinical value of miR-296 and its function in HCC remain poorly understood. In this study, we found that miR-296 levels are decreased in HCC specimens and cells, and that the underexpression of miR-296 is associated with adverse clinical parameters and poor overall survival rate. In vitro experiments indicate that miR-296 inhibits proliferation, colony formation, and cell cycle progression, and enhances apoptosis in HCC cells. Notably, we found that the fibroblast growth factor receptor 1 (FGFR1) is a downstream target that mediates the functions of miR-296 in HCC. Thus, our findings indicate that miR 296 exerts a tumor suppressive role in HCC and is a potential biomarker and drug target. PMID- 27714805 TI - Challenging of AS160/TBC1D4 Alters Intracellular Lipid milieu in L6 Myotubes Incubated With Palmitate. AB - The Akt substrate of 160 kDa (AS160) is a key regulator of GLUT4 translocation from intracellular depots to the plasma membrane in myocytes. Likely, AS160 also controls LCFAs transport, which requires relocation of fatty acid transporters. The aim of the present study was to determine the impact of AS160 knockdown on lipid milieu in L6 myotubes incubated with palmitate (PA). Therefore, we compared two different settings, namely: 1) AS160 knockdown prior to palmitate incubation (pre-PA-silencing, AS160- /PA); 2) palmitate incubation with subsequent AS160 knockdown (post-PA-silencing, PA/AS160- ). The efficiency of AS160 silencing was checked at mRNA and protein levels. The expression and localization of FA transporters were determined using Western Blot and immunofluorescence analyses. Intracellular lipid content (FFA, DAG, TAG, and PL) and FA composition were estimated by GLC, whereas basal palmitate uptake was analyzed by means of scintigraphy. Both groups with silenced AS160 were characterized by a greater expression of FA transporters (FAT/CD36, FATP-1, 4) which had contributed to an increased FA cellular influx. Accordingly, we observed that post-PA-silencing of AS160 resulted in a marked decrement in DAG, TAG, and PL contents, but increased FFA content (PA/AS160- vs. PA). The opposite effect was observed in the group with pre-PA-silencing of AS160 in which AS160 knockdown did not affect the lipid pools (AS160- /PA vs. PA). Our results indicate that post-PA-silencing of AS160 has a capacity to decrease the lipotoxic effect(s) of PA by decreasing the content of lipids (DAG and PL) that promote insulin resistance in myotubes.

PMID- 27714807 TI - Tiny estimates of the Ne /N ratio in marine fishes: Are they real? AB - Theory and empirical estimates agree that the ratio of effective size (Ne ) to census size (N) falls roughly in the range 0.1-0.5 for most populations. In a number of marine species, however, genetic estimates of contemporary Ne /N are as much as 5-6 orders of magnitude lower. Although some mechanisms that could produce such tiny Ne /N ratios have been proposed, the subject remains controversial. This issue is important to resolve: if Ne /N can be 10-3 or smaller, marine fish populations that are quite large could be at genetic risk. Based on a recently-improved understanding of factors that influence Ne and Ne /N in species with overlapping generations, this paper evaluates conditions necessary to produce tiny Ne /N ratios in actual populations. These analyses show that although increased longevity, fecundity and variance in reproductive success that increase with age, and increased egg quality with age [the big old fat fecund female fish (BOFFFF) hypothesis] all reduce Ne /N, extreme scenarios are required to reduce Ne /N below about 0.01. Therefore, tiny Ne /N ratios require some version of Hedgecock's 'sweepstakes' hypothesis, whereby only a few families reproduce successfully. Simulations using common genetically-based estimators show that, when true Ne is very large (>=106 ), a substantial fraction of point estimates of Ne /N can be 10-3 or smaller. These results mean that tiny, genetically-based point estimates of Ne /N in large marine populations are expected to be quite common, even when the true Ne /N ratio is 'normal' (~0.1 or higher). Very large samples of individuals can reduce, but not eliminate, this problem. The simulation results also emphasize the importance of considering deviations from model assumptions (e.g. non-random sampling; weak selection or migration) that may be relatively small (and hence can generally be ignored when the signal is strong) but can lead to substantial biases when the drift signal is weak, as is likely for large marine populations. Empirical studies of this topic need to be able to distinguish between episodes of sweepstakes reproductive success that are ephemeral and lead to chaotic genetic patchiness, and those that are consistent enough across space and time to produce persistent evolutionary consequences. PMID- 27714808 TI - Subtle genetic population structure in Pacific halibut Hippoglossus stenolepis. AB - Pacific halibut Hippoglossus stenolepis from 10 sampling locations throughout their range were investigated for signs of population structure. Two genetic data sets were created: (1) all individuals (n = 828) at few anonymous microsatellite markers (number of loci = 16); (2) fewer individuals (n = 435) genotyped at anonymous as well as expressed sequence-tag linked microsatellites (number of loci = 61). A combination of multidimensional scaling plots, discriminant analysis of principal components and pairwise differentiation estimates suggested that samples from the Aleutian Islands, particularly the western Aleutian Islands, were genetically distinct from samples collected in other regions. In addition, outlier analyses found that two markers linked to expressed sequence tags may be under directional selection and could explain the differentiation among samples. These results confirm findings from previous research and suggest that population structure may exist within a current management unit (i.e. International Pacific Halibut Commission Regulatory Area 4B). PMID- 27714809 TI - Physical compatibility of total parenteral nutrition and drugs in Y-site administration to children from neonates to adolescents. AB - OBJECTIVES: Infusion of precipitate or destabilized emulsion can be harmful. The purpose of this study was to obtain Y-site compatibility data on intravenous drugs and total parenteral nutrition (TPN) relevant for children. METHODS: Two three-in-one TPN admixtures (Olimel N5E and Numeta G16E) used for children of different age groups were tested with ten drugs (ampicillin, ceftazidime, clindamycin, dexamethasone, fluconazole, fosphenytoin, furosemide, metronidazole, ondansetron and paracetamol). Drug : TPN ratios were estimated from a wide range of age and weight classes, and the most extreme mixing ratios (drug > TPN, TPN > drug) in addition to 1 + 1 were chosen. Assessment of potential precipitation was performed by subvisual particle counting, visual examinations and measurements of turbidity and pH. Emulsion stability was investigated by estimation of percentage of droplets above 5 MUm (PFAT5), mean droplet diameter and pH measurements. Complimentary theoretical evaluations were performed. KEY FINDINGS: Ampicillin, fosphenytoin and furosemide precipitated when mixed with TPN. The results for ceftazidime, clindamycin, dexamethasone, fluconazole, metronidazole, ondansetron and paracetamol suggest that they were compatible with either TPN in the tested concentrations. None of the drugs were found to destabilize the emulsions. CONCLUSION: Three drugs showed clear signs of precipitation when mixed with TPN and these products should not be co-administered in the same infusion line. PMID- 27714811 TI - Inhibitory Effects of Quercetin on Progression of Human Choriocarcinoma Cells Are Mediated Through PI3K/AKT and MAPK Signal Transduction Cascades. AB - As a major dietary flavonol, quercetin mitigates proliferation and progression of cancer due to its anti-angiogenic, anti-inflammatory, anti-oxidant, and apoptotic biological effects on cells. Although its apoptotic effects have been reported for various cancers, little is known of the functional role of quercetin in gestational choriocarcinoma. Results of the present study indicated that quercetin reduced proliferation and induced cell death in two choriocarcinoma cell lines, JAR and JEG3 cells, with an increase in the sub-G1 phase of the cell cycle. In addition, quercetin induced mitochondrial dysfunction significantly reduced mitochondrial membrane potential (MMP) and increased production of reactive oxygen species (ROS) in both JAR and JEG3 cells. Further, quercetin inhibited phosphorylation of AKT, P70S6K and S6 proteins whereas, it increased phosphorylation of ERK1/2, P38, JNK and P90RSK proteins in JAR and JEG3 cells. The decrease in viability of choriocarcinoma cells treated with quercetin was confirmed by using combinations of quercetin and pharmacological inhibitors of the PI3K and MAPK signaling pathways. Classical chemotherapeutic agents, cisplatin (a platinum-based drug) and paclitaxel (a taxene-based drug), inhibited proliferation of JAR and JEG3 cells, and when combined with quercetin, the antiproliferative effects of cisplatin and paclitaxel were enhanced for both choriocarcinoma cell lines. Collectively, these results suggest that quercetin prevents development of choriocarcinoma and may be a valuable therapeutic agent for treatment of choriocarcinoma through its regulation of PI3K and MAPK signal transduction pathways.

PMID- 27714810 TI - Essential Role of CFTR in PKA-Dependent Phosphorylation, Alkalinization, and Hyperpolarization During Human Sperm Capacitation. AB - Mammalian sperm require to spend a limited period of time in the female reproductive tract to become competent to fertilize in a process called capacitation. It is well established that HCO3- is essential for capacitation because it activates the atypical soluble adenylate cyclase ADCY10 leading to cAMP production, and promotes alkalinization of cytoplasm, and membrane hyperpolarization. However, how HCO3- is transported into the sperm is not well understood. There is evidence that CFTR activity is involved in the human sperm capacitation but how this channel is integrated in the complex signaling cascades associated with this process remains largely unknown. In the present work, we have analyzed the extent to which CFTR regulates different events in human sperm capacitation. We observed that inhibition of CFTR affects HCO3- -entrance dependent events resulting in lower PKA activity. CFTR inhibition also affected cAMP/PKA-downstream events such as the increase in tyrosine phosphorylation, hyperactivated motility, and acrosome reaction. In addition, we demonstrated for the first time, that CFTR and PKA activity are essential for the regulation of intracellular pH, and membrane potential in human sperm. Addition of permeable cAMP partially recovered all the PKA-dependent events altered in the presence of inh-172 which is consistent with a role of CFTR upstream of PKA activation. J. Cell.

AB - Chronic kidney disease (CKD) is a worldwide public health problem that affects millions of men and women of all ages and racial groups. Loss of mesangial cells (MC) represents an early common feature in the pathogenesis of CKD. Transforming growth factor-beta1 (TGF-beta1) is a key inducer of kidney damage and triggers several pathological changes in renal cells, notably MC apoptosis. However, the mechanism of MC apoptosis induced by TGF-beta1 remains elusive. Here, we demonstrate for the first time a novel regulatory pathway in which the disheveled binding antagonist of beta-catenin 1 (Dact1) gene is upregulated by TGF-beta1, inducing MC apoptosis. We also show that the inhibitory effect of Dact1 and TGF beta1 on the transcriptional activation of the pro-survival Wnt pathway is the mechanism of death induction. In addition, Dact1 mRNA/protein levels are increased in kidney remnants from 5/6 nephrectomized rats and strongly correlate with TGF-beta1 expression. Together, our results point to Dact1 as a novel element controlling MC survival that is causally related to CKD progression. J. Cell. Physiol. 232: 2104-2111, 2017. (c) 2016 Wiley Periodicals, Inc.

AB - OBJECTIVES: Dendritic cells (DCs) are antigen-presenting cells, essential for recognition and presentation of pathogens to T cells. Propolis, a resinous material produced by bees from various plants, exhibits numerous biological properties, highlighting its immunomodulatory action. Here, we assayed the effects of propolis on the maturation and function of human DCs. METHODS: DCs were generated from human monocytes and incubated with propolis and LPS. NF kappaB and cytokines production were determined by ELISA. microRNA's expression was analysed by RT-qPCR and cell markers detection by flow cytometry. Colony forming units were obtained to assess the bactericidal activity of propolis treated DCs. KEY FINDINGS: Propolis activated DCs in the presence of LPS, inducing NF-kB, TNF-alpha, IL-6 and IL-10 production. The inhibition of hsa-miR 148a and hsa-miR-148b abolished the inhibitory effects on HLA-DR and pro inflammatory cytokines. The increased expression of hsa-miR-155 may be correlated to the increase in TLR-4 and CD86 expression, maintaining LPS-induced expression of HLA-DR and CD40. Such parameters may be involved in the increased bactericidal activity of DCs against Streptococcus mutans. CONCLUSION: Propolis modulated the maturation and function of DCs and may be useful in the initial steps of the immune response, providing a novel approach to the development of DC-based strategies and for the discovery of new immunomodulators.

AB - As the result of the communist terror in Poland, during years 1944-1956 more than 50,000 people died. Their bodies were buried secretly, and most places are still unknown. The research presents the results of identification of people buried in one of many mass graves, which were found at the cemetery Powazki Military in Warsaw, Poland. Exhumation revealed the remains of eight people, among which seven were identified genetically. Well-preserved molars were used for the study. Reference material was collected from the closest living relatives. In one case, an exhumation of victim's parents had to be performed. DNA from swabs was extracted with a PrepFiler(r) BTA Forensic DNA Extraction Kit and organic method. Autosomal, Y-STR amplification, and mtDNA sequencing were performed. The biostatistical calculations resulted in LR values from 1608 to 928 * 1018 . So far, remains of more than 50 victims were identified. PMID- 27714815 TI - Osteoclast Fusion: Time-Lapse Reveals Involvement of CD47 and Syncytin-1 at Different Stages of Nuclearity. AB - Investigations addressing the molecular keys of osteoclast fusion are primarily based on end-point analyses. No matter if investigations are performed in vivo or in vitro the impact of a given factor is predominantly analyzed by counting the number of multi-nucleated cells, the number of nuclei per multinucleated cell or TRAcP activity. But end-point analyses do not show how the fusion came about. This would not be a problem if fusion of osteoclasts was a random process and occurred by the same molecular mechanism from beginning to end. However, we and others have in the recent period published data suggesting that fusion partners may specifically select each other and that heterogeneity between the partners seems to play a role. Therefore, we set out to directly test the hypothesis that fusion factors have a heterogenic involvement at different stages of nuclearity. Therefore, we have analyzed individual fusion events using time-lapse and antagonists of CD47 and syncytin-1. All time-lapse recordings have been studied by two independent observers. A total of 1808 fusion events were analyzed. The present study shows that CD47 and syncytin-1 have different roles in osteoclast fusion depending on the nuclearity of fusion partners. While CD47 promotes cell fusions involving mono-nucleated pre-osteoclasts, syncytin-1 promotes fusion of two multi-nucleated osteoclasts, but also reduces the number of fusions between mono-nucleated pre-osteoclasts. Furthermore, CD47 seems to mediate fusion mostly through broad contact surfaces between the partners' cell membrane while syncytin 1 mediate fusion through phagocytic-cup like structure. J. Cell.

AB - Glioblastoma (GBM) are the most common and aggressive tumors of human brain. Recent studies showed that human cytomegalovirus (HCMV) can induce malignant transformation of tumor cells to maintain stemness. Transcription factor 5 (ATF5) is an anti-apoptotic protein that is highly expressed in malignant glioma. The aim of this study is to investigate the effect of HCMV infection on the stem cell makers of U251 cells. U251 cells were infected by AD169 HCMV strain (MOI = 1). The expression of stem cell makers (CD133, NES, Notch1) in infected U251 cells were compared with the expression in uninfected U251 cell to see the difference between them. Then, the changes of cell proliferation activity and the expression level of Notch intracellular domain (NICD), Notch1, ATF5, and IE protein were detected in the infected cells, and the expressions of Notch1 and NICD were increased. Cell proliferation assay showed that HCMV infection significantly increased the proliferation. These cells could form tumor spheres in non-adherent conditions. Consistent with these findings, the effect of silencing ATF5 on the proliferation of HCMV-infected U251 cells was also examined. The result shows that short interfering RNA-mediated ATF5 downregulation inhibited this process. These findings imply that HCMV infection may regulate ATF5 signaling pathway to increase cell malignant traits and maintain stemness. J. Med. Virol. 89:878-886, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27714817 TI - Effect of solvent on retarding the release of diltiazem HCl from Polyox-based liquisolid tablets. AB - OBJECTIVES: The aim of this work was to investigate the use of liquisolid technique to sustain the release of a model highly soluble drug, diltiazem HCl, from liquisolid matrices containing Polyox, a recently proposed matrix-forming hydrophilic polymer as an alternative to hypromellose. METHODS: Polyox-based liquisolid formulations prepared using several non-volatile solvents (i.e. polysorbate 80, polyethylene glycol, polyethylene glycol 200 and polyethylene glycol 600) and then characterised using differential scanning calorimetry and powder X-ray diffraction. The influence of solvent on retarding the release of diltiazem HCl from Polyox-based liquisolid tablets compared to conventional physical mixture tablets was studied. KEY FINDINGS: Liquisolid tablets exhibited greater retarding properties compared to conventional tablets. The use of polysorbate produced a slower release pattern of the drug from diltiazem hydrochloride (DTZ) liquisolid tablets compared to propylene glycol and polyethylene glycol (200 and 600). The release retardation was decreased with the increase in the concentration of the drug within drug:solvent liquid medication used. Solid-state analysis suggested the presence of a fraction of the drug mass in a solubilised state within polysorbate in liquisolid powders. CONCLUSION: Polyox-based matrix tablets prepared using liquisolid technique in the presence of a carefully selected non-volatile solvent could produce desirable, more sustained release profiles of highly water-soluble drugs compared to conventional physical mixture tablets.

AB - BACKGROUND: Using a norfloxacin (NFLX)-Nd3+ -cetyltrimethylammonium bromide (CTAB) system for the detection of NFLX, a simple and sensitive method based on fluorescence enhancement was developed. RESULTS: In pH 7.0 buffer solution, NFLX reacted with Nd3+ to form a complex, which resulted in fluorescence enhancement of NFLX, and the maximum emission peak shifted from 415 nm for NFLX to 450 nm for NFLX-Nd3+ . Moreover, the fluorescence intensity increased further when the surfactant CTAB was added to NFLX-Nd3+ . Under the optimum conditions, the fluorescence intensity of the NFLX-Nd3+ -CTAB system was linearly correlated with the NFLX concentration in the range 0.038-10 umol L-1 , with a correlation coefficient (R2 ) of 0.9997. The detection limit (3sigma/k) was 0.021 umol L-1 , indicating that this method can be applied to detect trace NFLX levels. The mechanism of fluorescence enhancement is discussed. The method was used to detect NFLX in fish and chicken samples with satisfactory results. CONCLUSION: The present results indicate that this method has the potential for fast and real time determination of NFLX in food samples (c) 2016 Society of Chemical Industry. PMID- 27714819 TI - Short- and Long-Term Hindlimb Immobilization and Reloading: Profile of Epigenetic Events in Gastrocnemius. AB - Skeletal muscle dysfunction and atrophy are characteristic features accompanying chronic conditions. Epigenetic events regulate muscle mass and function maintenance. We hypothesized that the pattern of epigenetic events (muscle enriched microRNAs and histone acetylation) and acetylation of transcription factors known to signal muscle wasting may differ between early- and late-time points in skeletal muscles of mice exposed to hindlimb immobilization (I) and recovery following I. Body and muscle weights, grip strength, muscle-enriched microRNAs, histone deacetylases (HDACs), acetylation of proteins, histones, and transcription factors (TF), myogenic TF factors, and muscle phenotype were assessed in gastrocnemius of mice exposed to periods (1, 2, 3, 7, 15, and 30 days, I groups) of hindlimb immobilization, and in those exposed to reloading for different periods of time (1, 3, 7, 15, and 30 days, R groups) following 7-day immobilization. Compared to non-immobilized controls, muscle weight, limb strength, microRNAs, especially miR-486, SIRT1 levels, and slow- and fast-twitch cross-sectional areas were decreased in mice of I groups, whereas Pax7 and acetylated FoxO1 and FoxO3 levels were increased. Muscle reloading following splint removal improved muscle mass loss, strength, and fiber atrophy, by increasing microRNAs, particularly miR-486, and SIRT1 content, while decreasing acetylated FoxO1 and FoxO3 levels. In this mouse model of disuse muscle atrophy, muscle-enriched microRNAs, especially miR-486, through Pax7 regulation delayed muscle cell differentiation following unloading of gastrocnemius muscle. Acetylation of FoxO1 and 3 seemed to drive muscle mass loss and atrophy, while deacetylation of these factors through SIRT1 would enable the muscle fibers to regenerate. J. Cell.

AB - BACKGROUND: Maize was grown on compound soils constituted from mixtures of soft rock and sand at different ratios, and water use efficiency (WUE), nitrogen use efficiency (NUE) and fertilizer nitrogen use efficiency (FNUE) were quantified. The data were used to assist in designing strategies for optimizing water and nitrogen management practices for maize on the substrates used. Maize was sown in composite soil prepared at three ratios of soft rock and sand (1:1, 1:2 and 1:5 v/v) in Mu Us Sandy Land, Yuyang district, Yulin city, China. Yields, amount of drainage, nitrogen (N) leaching, WUE and NUE were calculated. Then a water and nitrogen management model (WNMM) was calibrated and validated. RESULTS: No significant difference in evapotranspiration of maize was found among compound soils with soft rock/sand ratios of 1:1, 1:2 and 1:5, while water drainage increased significantly with increasing soft rock/sand ratio. WUE increased to 1.30 kg m-3 in compound soil with 1:2 soft rock/sand ratio. Nitrogen leaching and ammonia volatilization were the main reason for nitrogen loss, and N reduction mainly relied on crop uptake. NUE and FNUE could reach 33.1 and 24.9 kg kg-1 N respectively. Water drainage and nitrogen leaching occurred mostly during heavy rainfall or irrigation. Through a scenario analysis of different rainfall types, water and fertilizer management systems were formulated each year. CONCLUSION: This study shows that soft rock plays a key role in improving the WUE, NUE and FNUE of maize. (c) 2016 Society of Chemical Industry. PMID- 27714821 TI - An association of type 1 diabetes mellitus with auditory dysfunction: A systematic review and meta-analysis. AB - OBJECTIVE: To establish the relationship between the presence of type 1 diabetes mellitus (DM) and auditory dysfunction in clinical settings by a systematic review and meta-analysis of currently available published data. DATA SOURCES AND REVIEW METHODS: The electronic databases PubMed, Embase, and Wanfang Data were searched for eligible relevant studies up to May 2016, and the reference lists of the retrieved articles were used for additional manual search. All the articles included in this pooled analysis were determined according to the preset inclusion and exclusion criteria. Meta-analysis of pooled data was performed using Review Manager 5.3. RESULTS: A total of 15 studies were included for further combined analysis. The results showed that patients with type 1 diabetes had a significantly higher prevalence of hearing loss than controls (odds ratio = 49.08, 95% confidence interval = 12.03-200.31, P < 0.00001); standardized mean of differences (SMD) of pure tone audiometry at 4,000 Hz between diabetes and controls was 0.87 (Z = 2.22, P = 0.03, I2 = 95%); SMD of the latency time was 0.54 (Z = 2.69, P = 0.007, I2 = 78%) for waves III and 0.61 (Z = 2.38, P = 0.02, I2 = 86%) for wave V, respectively; and SMD of the interpeak latency time was 0.41 (Z = 2.84, P = 0.005, I2 = 39%) for waves I to III and 0.61 (Z = 2.67, P = 0.008, I2 = 81%) for waves I to V, respectively, between diabetics and controls. CONCLUSION: Our study reveals that there is relationship between the presence of type 1 DM and an increased risk for developing mild and subclinical hearing impairment. LEVEL OF EVIDENCE: NA.

Biomass production and its dehydration produce major oxidative stress, while hyperosmotic shock, ethanol toxicity and starvation are relevant during grape juice fermentation. Most stress response mechanisms described in laboratory strains of Saccharomyces cerevisiae are useful for understanding the molecular machinery devoted to deal with harsh conditions during industrial wine yeast uses. However, the particularities of these strains themselves, and the media and conditions employed, need to be specifically looked at when studying protection mechanisms.

PMID- 27714824 TI - Quorum sensing influences phage infection efficiency via affecting cell population and physiological state. AB - Bacterial growth phase has been reported affecting phage infection. To underpin the related mechanism, infection efficiency of Pseudomonas aeruginosa phage K5 is characterized. When infecting the logarithmic cells, phage K5 produced significantly more infection centers than the stationary cells, well concordant with the viable cell ratio in the different growth phases. Additionally, the burst size decreased dramatically in the stationary cells, implying that the physiological state of the viable cells contributed to the productivity of phage K5, and it was consistent with the expression variation of the phage RNA polymerase. Quorum sensing inhibitor penicillic acid was applied and could significantly improve the viable cell proportion and the infection center numbers, but had less effect on the corresponding burst sizes. Moreover, the effect of penicillic acid and the quorum sensing regulator mutants on the production of phage C11 was also analyzed. Taken together, our data suggest that quorum sensing is involved in the defense of phage K5 infection by influencing the viable cell population and their physiological state, and it is an efficient and intrinsic pathway allowing bacteria to resist phage attacks in natural environment. PMID- 27714825 TI - Stress of algicidal substances from a bacterium Exiguobacterium sp. h10 on Microcystis aeruginosa. AB - : Microcystis aeruginosa is a cyanobacterial bloom-causing species and is considered a serious threat to human health and biological safety. In this study, the algicidal bacterium h10 showed high algicidal effects on M. aeruginosa 7820, and strain h10 was confirmed to belong to the genus Exiguobacterium, for which the name Exiguobacterium sp. h10 is proposed. Algicidal activity and mode analysis revealed that the supernatant, rather than the bacterial cells, was responsible for the algicidal activity, indicating that the algicidal mode of strain h10 is by indirect attack through the production of algicidal substances. Analysis of the algicidal substance characteristics showed a molecular weight of <1000 Da and that algicidal substances exhibit high thermal stability and pH instability, and the characteristic functional groups of the algicidal substance mainly included carbonyl, amino and hydroxyl groups. Under the effects of the algicidal substance, the cellular pigment content was significantly decreased, and the algal cell structure and morphology were seriously damaged. The results indicate that the algicidal bacterium Exiguobacterium sp. h10 could be a potential bio-agent for controlling cyanobacterial blooms of M. aeruginosa. SIGNIFICANCE AND IMPACT OF THE STUDY: In this study, the effects of algicidal substances from an algicidal bacterium Exiguobacterium sp. h10 on the toxic cyanobacterium, Microcystis aeruginosa 7820, were first investigated. The algicidal mode of action was confirmed as an indirect attack through the production of algicidal substances. The characteristics of the algicidal substance were determined, especially the functional groups analysis that confirmed the algicidal substances were glycolipid mixtures. With the stress of algicidal substances, the algal chlorophyll a synthesis, cell structure and morphology were seriously damaged. This study proved that algicidal bacteria are promising sources of potential cyanobacterial bloom-control, and provided good procedures for the identification and analysis of an algicidal bacterium and substances. PMID- 27714826 TI - Multi-scale graph-cut algorithm for efficient water-fat separation. AB - PURPOSE: To improve the accuracy and robustness to noise in water-fat separation by unifying the multiscale and graph cut based approaches to B0 -correction. METHODS: A previously proposed water-fat separation algorithm that corrects for B0 field inhomogeneity in 3D by a single quadratic pseudo-Boolean optimization (QPBO) graph cut was incorporated into a multi-scale framework, where field map solutions are propagated from coarse to fine scales for voxels that are not resolved by the graph cut. The accuracy of the single-scale and multi-scale QPBO algorithms was evaluated against benchmark reference datasets. The robustness to noise was evaluated by adding noise to the input data prior to water-fat separation. RESULTS: Both algorithms achieved the highest accuracy when compared with seven previously published methods, while computation times were acceptable for implementation in clinical routine. The multi-scale algorithm was more robust to noise than the single-scale algorithm, while causing only a small increase (+10%) of the reconstruction time. CONCLUSION: The proposed 3D multi-scale QPBO algorithm offers accurate water-fat separation, robustness to noise, and fast reconstruction. The software implementation is freely available to the research community. Magn Reson Med 78:941-949, 2017. (c) 2016 International Society for Magnetic Resonance in Medicine. PMID- 27714827 TI - Immunomodulatory effects of metal salts at sub-toxic concentrations. AB - Because different metals are used in complementary medicine for the treatment of diseases related to a dysfunction of the immune system, this study aimed at determining the immunomodulatory potential of Pb(NO3 )2 , AuCl3 , Cu(NO3 )2 , HgCl2 , AgNO3 , SnCl2 , AsCl3 and SbCl3 at sub-toxic concentrations and at assessing possible toxic side effects of low-concentrated metal preparations. The influence of the metal salts on primary human mononuclear cells was analyzed by measuring cell viability using the water-soluble tetrazolium salt assay, apoptosis and necrosis induction by annexin V/propidium iodide staining and proliferation by carboxyfluorescein diacetate succinimidyl ester staining and flow cytometry. Effects on T-cell activation were assessed with CD69 and CD25 expression using flow cytometry whereas CD83, CD86 and CD14 expression was measured to evaluate the influence on dendritic cell maturation. Alterations of interleukin-2 and interferon-gamma secretion were detected by enzyme-linked immunosorbent assay and genotoxic effects were analyzed using the comet assay. At sub-toxic concentrations retardation of T-cell proliferation was caused by Pb(NO3 )2 , AuCl3 and Cu(NO3 )2 and inhibitory effects on interleukin-2 secretion were measured after incubation with Pb(NO3 )2 , AuCl3 , Cu(NO3 )2 , HgCl2 and AsCl3. Cu(NO3 )2 had immunosuppressive activity at dosages within the serum reference range for copper. All other metal salts showed effects at dosages above upper serum limits of normal. Therefore, only low-concentrated copper preparations are promising to have immunomodulatory potential. Toxic side effects of metal preparations used in complementary medicine are improbable because upper limits of metals set in the drinking water ordinance are either not exceeded or the duration of their application is limited.

AB - Despite the absence of any homologs of Tannerella forsythia KLIKK proteases in Tannerella sp.6_1_58FAA_CT1, the strain possesses a putative cysteine protease (G9S4N1) closely related to RgpB of Porphyromonas gingivalis. G9S4N1 lacks obvious propeptide that behaves as inhibitor of proteases and was proven to be a propeptide-independent protease. Unlike RgpB, which exclusively cleaves Arg?Xaa bonds, G9S4N1 exhibits both arginine- and citrulline-specific activities. Mutations of Asp177, a potential P1-Arg binding site, to uncharged or positively charged residues did not alter the substrate specificity of G9S4N1 significantly. Moreover, a group of arginine-specific proteases from different species including porcine trypsin, bovine thrombin, and a trypsin-like serine protease of dengue 2 virus CF40-Gly-NS3pro185 also display different specificity toward citrulline residue, suggesting that citrulline-modified protein might have different roles and destiny in biological processes involving various proteases. PMID- 27714829 TI - Biological factor related to Asian sand dust particles contributes to the exacerbation of asthma. AB - Epidemiologic studies have revealed that Asian sand dust particles (ASDs) can affect respiratory and immune health represented by asthma. Factors responsible for the exacerbation of asthma remain unclear. The fungus Bjerkandera adusta (B.ad) and polycyclic aromatic hydrocarbons such as benzo[a]pyrene (BaP) have been identified in ASDs collected from the atmosphere when an ASD event occurred. We investigated the effects of B.ad and BaP related to ASDs on respiratory and immune systems. Bone marrow-derived antigen-presenting cells (APCs) and splenocytes from atopic prone NC/Nga mice and human airway epithelial cells were exposed to the B.ad or to BaP in the presence and absence of heated-ASDs (H ASDs). B.ad and BaP in both the presence and absence of H-ASDs increased the expression of cell surface molecules on APCs. H-ASDs alone slightly activated APCs. The expressions induced by B.ad were higher than those induced by BaP in the presence and absence of H-ASDs. There were no remarkable effects on the activation of splenocytes or the proinflammatory responses in airway epithelial cells. These results suggest that B.ad rather than BaP contributes to the exacerbation of asthma regardless of the presence or absence of sand particles, particularly by the activation of the immune system via APCs.

AB - This study describes the development of simple, rapid and sensitive liquid chromatography tandem mass spectrometry method for the simultaneous analysis of doxorubicin and its major metabolite, doxorubicinol, in mouse plasma, urine and tissues. The calibration curves were linear over the range 5-250 ng/mL for doxorubicin and 1.25-25 ng/mL for doxorubicinol in plasma and tumor, over the range 25-500 ng/mL for doxorubicin and 1.25-25 ng/mL for doxorubicinol in liver and kidney, and over the range 25-1000 ng/mL for doxorubicin and doxorubicinol in urine. The study was validated, using quality control samples prepared in all different matrices, for accuracy, precision, linearity, selectivity, lower limit of quantification and recovery in accordance with the US Food & Drug Administration guidelines. The method was successfully applied in determining the pharmaco-distribution of doxorubicin and doxorubicinol after intravenously administration in tumor-bearing mice of drug, free or nano-formulated in ferritin nanoparticles or in liposomes. Obtained results demonstrate an effective different distribution and doxorubicin protection against metabolism linked to nano-formulation. This method, thanks to its validation in plasma and urine, could be a powerful tool for pharmaceutical research and therapeutic drug monitoring, which is a clinical approach currently used in the optimization of oncologic treatments. PMID- 27714831 TI - Vedolizumab provides clinical benefit over 1 year in patients with active inflammatory bowel disease - a prospective multicenter observational study. AB - BACKGROUND: Vedolizumab, a monoclonal antibody targeting the alpha4beta7 integrin, is effective in inducing and maintaining clinical remission in Crohn's disease and ulcerative colitis according to randomised clinical trials. AIM: To determine the long-term effectiveness of vedolizumab in a real-world clinical setting. METHODS: This observational registry assessed the clinical outcome in patients treated with vedolizumab for clinically active Crohn's disease (n = 67) or ulcerative colitis (n = 60). Primary endpoint was clinical remission (HBI <= 4/pMayo <= 1) at week 54. Secondary endpoints included clinical response rates (HBI/pMayo score drop >=3) and steroid-free clinical remission at weeks 30 and 54. RESULTS: Vedolizumab was stopped in 69/127 (56%) patients after a median time of 18 weeks (range 2-49) predominantly owing to lack or loss of response. Using nonresponder imputation analysis, clinical remission and steroid-free remission rates were 21% and 15% in Crohn's disease and 25% and 22% in ulcerative colitis, respectively. Lack of clinical remission was associated with prior treatment with anti-TNF or with steroids for more than 3 months in the last 6 months in ulcerative colitis. At week 14, the absence of remission in Crohn's disease or nonresponse in ulcerative colitis indicated a low likelihood of clinical remission at week 54 [2/31 (7%) in Crohn's disease, 4/41 (10%) in ulcerative colitis]. Accordingly, declining C-reactive protein in inflammatory bowel disease and/or lower faecal calprotectin in ulcerative colitis at week 14 predicted remission at week 54. CONCLUSION: Among patients who started vedolizumab for active inflammatory bowel disease, clinical remission rates are 21-25% after 54 weeks.

AB - PURPOSE: To optimize the production of hyperpolarized 13 C-bicarbonate from the decarboxylation of hyperpolarized [1-13 C]pyruvate and use it to image pH in the lungs and heart of rats with acute lung injury. METHODS: Two forms of catalysis are compared calorimetrically to maximize the rate of decarboxylation and rapidly produce hyperpolarized bicarbonate from pyruvate while minimizing signal loss. Rats are injured using an acute lung injury model combining ventilator-induced lung injury and acid aspiration. Carbon images are obtained from both healthy (n = 4) and injured (n = 4) rats using a slice-selective chemical shift imaging sequence with low flip angle. pH is calculated from the relative HCO3- and CO2 signals using the Henderson-Hasselbalch equation. RESULTS: It is demonstrated that base catalysis is more effective than metal-ion catalysis for this decarboxylation reaction. Bicarbonate polarizations up to 17.2% are achieved using the base-catalyzed reaction. A mean pH difference between lung and heart of 0.14 pH units is measured in the acute lung injury model. A significant pH difference between injured and uninjured lungs is also observed. CONCLUSION: It is demonstrated that hyperpolarized 13 C-bicarbonate can be efficiently produced from the base-catalyzed decarboxylation of pyruvate. This method is used to obtain the first regional pH image of the lungs and heart of an animal. Magn Reson Med 78:1121-1130, 2017. (c) 2016 International Society for Magnetic Resonance in Medicine.

PMID- 27714835 TI - Comparison of the local pulmonary distribution of nanoparticles administered intratracheally to rats via gavage needle or microsprayer delivery devices. AB - Intratracheal administration methods are used to conduct toxicological assessments of inhaled nanoparticles (NPs), and gavage needles or microsprayers are common intratracheal delivery devices. The NP suspension is delivered in a liquid state via gavage needle and as a liquid aerosol via microsprayer. The differences in local pulmonary NP distribution (called the microdistribution) arising from the different states of the NP suspension cause differential pulmonary responses; however, this has yet to be investigated. Herein, using microbeam X-ray fluorescence microscopy, we quantitatively evaluated the TiO2 pulmonary microdistribution (per mesh: 100 MUm * 100 MUm) in lung sections from rats administered an intratracheal dose of TiO2 NPs (6 mg kg-1 ) via gavage needle or microsprayer. The results revealed that: (i) using a microsprayer appears to reduce the variations in TiO2 content (ng mesh-1 ) among rats (e.g., coefficients of variation, n = 3, microsprayer vs gavage needle: 13% vs 30%, for the entire lungs); (ii) TiO2 appears to be deposited less in the right middle lobes than in the rest of the lung lobes, irrespective of the chosen intratracheal delivery device; and (iii) similar TiO2 contents (ng mesh-1 ) and frequencies are deposited in the lung lobes of rats administered TiO2 NPs via gavage needle or microsprayer. This suggests that the physical state of the administered NP suspension does not markedly alter TiO2 pulmonary microdistribution. The results of this investigation are important for the standardization of intratracheal administration methods. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - Because of its ecological and economic importance, the honey bee Apis mellifera is commonly used to assess the environmental risk of insect-resistant, genetically modified plants. In the present study, feeding-exposure experiments were used to determine whether pollen from transgenic rice harms A. mellifera worker bees. In 1 experiment, the survival and mean acinus diameter of hypopharyngeal glands of adult bees were similar when bees were fed on pollen from Bt rice lines or from a non-Bt rice line, but bee survival was significantly reduced when they received pollen that was mixed with potassium arsenate as a positive control. In a second experiment, bee survival and hypopharyngeal gland development were not reduced when adult bees were fed on non-Bt pollen and a sucrose solution supplemented with Cry2A at 400 ug/g, Cry1C at 50 ug/g, or bovine serum albumin (BSA) at 400 ug/g, but bee survival and hypopharyngeal gland development were reduced when the diet was supplemented with soybean trypsin inhibitor as a positive control. In both experiments, the uptake of Cry proteins by adult bees was confirmed. Overall, the results indicate that the planting of Bt rice lines expressing Cry2A or Cry1C protein poses a negligible risk to A. mellifera worker bees. Environ Toxicol Chem 2017;36:1243-1248.

AB - It is widely accepted that adenosine triphosphate (ATP) acts as a universal danger-associated molecular pattern with several known mechanisms for immune cell activation. In the central nervous system, ATP activates microglia and astrocytes and induces a neuroinflammatory response. The aim of the present study was to describe responses of isolated astrocytes to increasing concentrations of ATP (5 uM to 1 mM), which were intended to mimic graded intensity of the extracellular stimulus. The results show that ATP induces graded activation response of astrocytes in terms of the cell proliferation, stellation, shape remodeling, and underlying actin and GFAP filament rearrangement, although the changes occurred without an apparent increase in GFAP and actin protein expression. On the other hand, ATP in the range of applied concentrations did not evoke IL-1beta release from cultured astrocytes, nor did it modify the release from LPS and LPS+IFN gamma-primed astrocytes. ATP did not promote astrocyte migration in the wound healing assay, nor did it increase production of reactive oxygen and nitrogen species and lipid peroxidation. Instead, ATP strengthened the antioxidative defense of astrocytes by inducing Cu/ZnSOD and MnSOD activities and by increasing their glutathione content. Our current results suggest that although ATP triggers several attributes of activated astrocytic phenotype with a magnitude that increases with the concentration, it is not sufficient to induce full-blown reactive phenotype of astrocytes in vitro.

AB - PURPOSE: To illustrate the potential for high permittivity materials to be used in decreasing peak local SAR associated with implants when the imaging region is far from the implant. METHODS: We performed numerical simulations of a human subject with a pacemaker in a body-sized birdcage coil driven at 128 MHz with and without a thin (5 mm) shell of material of high electric permittivity around the head. RESULTS: For a shell with relative permittivity of 600, the maximum specific energy absorption rate averaged over any 1 g of tissue near the pacemaker was reduced by 73.5% for a given B1 field strength at the center of the brain. CONCLUSION: Although further study is required, initial simulations indicate that strategic use of high permittivity materials may broaden the conditions under which patients with certain implants can be imaged safely.

PMID- 27714838 TI - Pharmacologically Inactive Bisphosphonates as an Alternative Strategy for Targeting Osteoclasts: In Vivo Assessment of 5-Fluorodeoxyuridine-Alendronate in a Preclinical Model of Breast Cancer Bone Metastases. AB - Bisphosphonates have effects that are antiresorptive, antitumor, and antiapoptotic to osteoblasts and osteocytes, but an effective means of eliciting these multiple activities in the treatment of bone metastases has not been identified. Antimetabolite-bisphosphonate conjugates have potential for improved performance as a class of bone-specific antineoplastic drugs. The primary objective of the study was to determine whether an antimetabolite-bisphosphonate conjugate will preserve bone formation concomitant with antiresorptive and antitumor activity. 5-FdU-ale, a highly stable conjugate between the antimetabolite 5-fluoro-2'-deoxyuridine and the bisphosphonate alendronate, was tested for its therapeutic efficacy in a mouse model of MDA-MB231 breast cancer bone metastases. In vitro testing revealed osteoclasts to be highly sensitive to 5-FdU-ale. In contrast, osteoblasts had significantly reduced sensitivity. Tumor cells were resistant in vitro but in vivo tumor burden was nevertheless significantly reduced compared with untreated mice. Sensitivity to 5-FdU-ale was not mediated through inhibition of farnesyl diphosphate synthase activity, but cell cycle arrest was observed. Although serum tartrate-resistant acid phosphatase (TRAP) levels were greatly reduced by both drugs, there was no significant decrease in the serum bone formation marker osteocalcin with 5-FdU ale treatment. In contrast, there was more than a fivefold decrease in serum osteocalcin levels with alendronate treatment (p < 0.001). This finding is supported by time-lapse micro-computed tomography analyses, which revealed bone formation volume to be on average 1.6-fold higher with 5-FdU-ale treatment compared with alendronate (p < 0.001). We conclude that 5-FdU-ale, which is a poor prenylation inhibitor but maintains potent antiresorptive activity, does not reduce bone formation and has cytostatic antitumor efficacy. These results document that conjugation of an antimetabolite with bisphosphonates offers flexibility in creating potent bone-targeting drugs with cytostatic, bone protection properties that show limited nephrotoxicity. This unique class of drugs may offer distinct advantages in the setting of targeted adjuvant therapy and chemoprevention of bone diseases. (c) 2016 American Society for Bone and Mineral Research. PMID- 27714840 TI - An analysis of free flap failure using the ACS NSQIP database. Does flap site and flap type matter? AB - PURPOSE: We sought to use the NSQIP database to determine the national rate and predictors of free flap failure based upon flap sites and flap types. METHODS: Free flaps were identified using the 2005-2010 NSQIP database. We examined overall flap failure rates as well as failure rates based upon flap sites (head and neck, extremities, trunk, and breast) and flap types (muscle, fascial, skin, bone, and bowel flaps). Univariate and multivariate analyses were used to determine predictors of flap failure. RESULTS: There were 1,187 microvascular free tissue transfers identified. The overall flap failure rate was 5.1%. Head and neck flaps had the highest rate of free flap failure at 7.7%. Prolonged operative time is an independent predictor of flap failure for all free flaps (OR: 2.383, P = 0.0013). When examining predictors of failure by flap site, free flaps to the breast with prolonged operative time are independently associated with flap failure (OR: 2.288, P = 0.0152). When examining predictors of flap failure by flap type, muscle based free flaps with an ASA classification >=3 are associated with flap failure (P = 0.0441). CONCLUSIONS: Risk factors for free flap failure differ based upon flap site and flap type. Prolonged operative time is an independent risk factor for the failure of free flaps used for breast reconstruction. An ASA classification >=3 is associated with the failure of free muscle based flaps. Our findings identify actionable areas that may help to improve free flap success. PMID- 27714841 TI - Random effects meta-analysis: Coverage performance of 95% confidence and prediction intervals following REML estimation. AB - A random effects meta-analysis combines the results of several independent studies to summarise the evidence about a particular measure of interest, such as a treatment effect. The approach allows for unexplained between-study heterogeneity in the true treatment effect by incorporating random study effects about the overall mean. The variance of the mean effect estimate is conventionally calculated by assuming that the between study variance is known; however, it has been demonstrated that this approach may be inappropriate, especially when there are few studies. Alternative methods that aim to account for this uncertainty, such as Hartung-Knapp, Sidik-Jonkman and Kenward-Roger, have been proposed and shown to improve upon the conventional approach in some situations. In this paper, we use a simulation study to examine the performance of several of these methods in terms of the coverage of the 95% confidence and prediction intervals derived from a random effects meta-analysis estimated using restricted maximum likelihood. We show that, in terms of the confidence intervals, the Hartung-Knapp correction performs well across a wide-range of scenarios and outperforms other methods when heterogeneity was large and/or study sizes were similar. However, the coverage of the Hartung-Knapp method is slightly too low when the heterogeneity is low (I2 < 30%) and the study sizes are quite varied. In terms of prediction intervals, the conventional approach is only valid when heterogeneity is large (I2 > 30%) and study sizes are similar. In other situations, especially when heterogeneity is small and the study sizes are quite varied, the coverage is far too low and could not be consistently improved by either increasing the number of studies, altering the degrees of freedom or using variance inflation methods. Therefore, researchers should be cautious in deriving 95% prediction intervals following a frequentist random-effects meta-analysis until a more reliable solution is identified. (c) 2016 The Authors.

AB - PURPOSE: Pelvic lymph node (PLN) metastases are often smaller than 5 mm and difficult to detect. This work presents a method to perform PLN imaging with ultrahigh-field MRI, using spectrally selective excitation to acquire water and lipid-selective imaging at high spatial resolution. METHODS: A 3D water-selective multigradient echo (mGRE) sequence and lipid-selective gradient echo (GRE) sequence were tested in six healthy volunteers on a 7 Tesla (T) MRI system, using time interleaved acquisition of modes (TIAMO) to improve image homogeneity. The size distribution of the first 10 iliac PLNs detected in each volunteer was determined, and the contrast-to-noise ratio (CNR) of these lymph nodes (LNs) was compared with the individual mGRE images, sum-of-squares echo addition, and computed T2*-weighted images derived from the T2* fits. RESULTS: LN imaging was acquired robustly at ultrahigh field with high resolution and homogeneous lipid or water-selective contrast. PLNs down to 1.5-mm short axis were detected with mean +/- standard error of the mean (SEM) short and long axes of 2.2 +/- 0.1 and 3.7 +/- 0.2 mm, respectively. Computed T2*-weighted imaging allowed flexibility in T2* contrast while featuring a CNR up to 90% of the sum-of-squares echo addition. CONCLUSION: Ultrahigh-field MRI in combination with TIAMO and frequency selective excitation enables high-resolution, large field-of-view MRI of the lower abdomen, and may ultimately be suitable for detecting small PLN metastases.

AB - Traditional microscopy-based methods for diagnosis of bacterial vaginosis (BV) are underutilized in many settings, and molecular techniques may provide opportunities for rapid, objective, and accurate BV diagnosis. This study evaluated the quantitative AmpliSens Florocenosis/Bacterial vaginosis-FRT multiplex real-time PCR (Florocenosis-BV) assay. Vaginal samples from a previous study including unselected female subjects (n = 163) and using Amsel criteria and 454 pyrosequencing for BV diagnosis were examined with the Florocenosis-BV test and additionally tested for the presence and quantity of Gardnerella vaginalis clades 3 and 4. The Florocenosis-BV assay demonstrated 100% and 98% sensitivity compared with the Amsel criteria and 454 pyrosequencing, respectively, with 91% specificity. The modified Florocenosis-BV assay (detecting also G. vaginalis clades 3 and 4) resulted in 100% sensitivity vs the Amsel criteria and 454 pyrosequencing with specificity of 86% and 88%, respectively. Further optimizations of thresholds for the quantitative parameters used in the kit resulted in 99-100% accuracy vs Amsel criteria and 454 pyrosequencing for selected parameters. The Florocenosis-BV assay is an objective, accurate, sensitive, and specific method for BV diagnosis; however, the performance of the test can be further improved with some minor optimizations. PMID- 27714843 TI - Acute tendon changes in intense CrossFit workout: an observational cohort study. AB - CrossFit is a fitness program that has become increasingly popular in the Western world, but as in other sports, the risk of injury is present. Only a few studies have addressed health benefits and injuries in CrossFit. It is known that chronically overloaded tendons will thicken and increase the risk of tendinopathy. However, it remains unknown whether acute overload caused by strenuous, high-intensity exercise will exert changes in tendons and if these changes can be detected and described by ultrasonography. The aim of this study is to evaluate the effects of acute overload on tendon thickness using ultrasonography. Standardized ultrasound measurements of the patella, Achilles, and plantaris tendons were performed before and after a specific workout in 34 healthy subjects. Significant increases were observed in patella tendon thickness before (M = 4.5, SD = 0.6) and after (M = 5.0, SD = 0.7) highly intense strenuous exercise, with an estimated mean differences of 0.47 mm (95% CI: 0.35-0.59 mm; P < 0.0001) and in Achilles tendon thickness before (M = 4.4, SD = 0.4) and after (M = 4.5, SD = 0.5) workout, with an estimated difference of 0.17 mm (95% CI: 0.04-0.29 mm; P < 0.01). However, there was no significant difference in fascia plantaris thickness before (M = 3.4, SD = 0.5) and after (M = 3.4, SD = 0.5) workout (P = 0.97). A significant increase in the thickness of the patellar and Achilles tendons was found in response to strenuous, highly intense CrossFit exercises. In order to understand the underlying mechanisms of the findings and possibly utilize this to gain a better understanding, further studies must be conducted. PMID- 27714845 TI - Contact allergens induce CD8+ T cell-derived interleukin 10 that appears dispensable for regulation of contact hypersensitivity. AB - Interleukin 10 (IL-10) has been implied in the regulation of allergic contact dermatitis. Using transcriptional reporter mice we analyzed cellular sources of IL-10 during contact hypersensitivity (CHS) and identified IL-10 expressing CD8+ T cells in the skin that are antigen-specific, display PD-1, an effector memory phenotype, and IL-10 expression comparable to that of CD4+ T cells. However, in mice with a selective IL-10 deficiency in CD8+ T cells CHS responses were comparable to that of controls, even in the absence of CD4+ cells, suggesting that CD8+ T cell-derived IL-10 does not contribute significantly to the resolution of CHS responses. PMID- 27714846 TI - Both high expression of nucleophosmin/B23 and CRM1 predicts poorer prognosis in human gastric cancer. AB - Nucleophosmin/B23 and CRM1 are molecular markers which play an important role in tumorigenesis and tumor progression in gastric cancer (GC). However, the association between the two remains unclear. This study evaluated the expression and the correlation of B23 and CRM1 in GC. B23 and CRM1 expression in GC and adjacent noncancerous tissues (ANCT) of gastrectomy specimens from 131 GC patients was measured by immunohistochemistry. Positive expression rates of B23 and CRM1 were significantly higher in GC tissues than in ANCT. The high expression rates of B23 and CRM1 were significantly higher in patients with more advanced tumor stages and distant metastasis (all p < 0.05). Only high expression of CRM1was correlated with positive Her2 status (p = 0.01). B23 expression was positively correlated with CRM1expression in GC tissues (p = 0.038). Univariate analysis showed that TNM stage (p = 0.0001), metastasis (p = 0.027), B23 (p = 0.0111), and CRM1 expression (p = 0.0019) were significant risk factors affecting overall survival. Both high expression of B23 and CRM1 in GC patients suggests poor prognosis, co-expression of the two (p = 0.043) even worse. Cox multivariate analysis showed that positive B23 (p = 0.0231) and CRM1 (p = 0.0048) expression were both independent prognostic factors that negatively correlated with survival. We revealed the co-expression of B23 or CRM1 in GC. The expression levels of B23 or CRM1 were closely related to poor prognosis in GC, and both B23 or CRM1 were independent risk factor. PMID- 27714848 TI - The regulatable MAL32 promoter in Saccharomyces cerevisiae: characteristics and tools to facilitate its use. AB - Here we describe a set of tools to facilitate the use of maltose and the MAL32 promoter for regulated gene expression in yeast, alone or in combination with the GAL1 promoter. Using fluorescent protein reporters we find that under non inducing conditions the MAL32 promoter exhibits a low basal level of expression, similar to the GAL1 promoter, and that both promoters can be induced independently of each other using the respective sugars, maltose and galactose. While their repression upon glucose addition is immediate and complete, we found that the MAL32 and GAL1 promoters each exhibit distinct induction kinetics. A set of plasmids is available to facilitate the application of the MAL32 promoter for chromosomal modifications using PCR targetting and for plasmid based gene expression.

AB - Old age and sex steroid deficiency are the two most critical factors for the development of osteoporosis. It remains unknown, however, whether the molecular culprits of the two conditions are similar or distinct. We show herein that at 19.5 months of age-a time by which the age-dependent decline of cortical and cancellous bone mass and cortical porosity were fully manifested in C57BL/6J mice these animals remained functionally estrogen sufficient. Transgenic mice with conditional expression of mitochondria-targeted catalase-a potent H2 O2 inactivating enzyme-in cells of the myeloid lineage (mitoCAT;LysM-Cre mice) were protected from the loss of cortical, but not cancellous, bone caused by gonadectomy in either sex. Consistent with these findings, in vitro studies with ERalpha-deficient Prx1+ cells and gonadectomized young adult mice showed that in both sexes decreased ERalpha signaling in Prx1+ cells leads to an increase in SDF1, a.k.a. CXCL12, an osteoclastogenic cytokine whose effects were abrogated in macrophages from mitoCAT;LysM-Cre mice. In contrast to sex steroid deficiency, the adverse effects of aging on either cortical or cancellous bone were unaffected in mitoCAT;LysM-Cre mice. On the other hand, attenuation of H2 O2 generation in cells of the mesenchymal lineage targeted by Prx1-Cre partially prevented the loss of cortical bone caused by old age. Our results suggest the effects of sex steroid deficiency and aging on the murine skeleton are independent and result from distinct mechanisms. In the former, the prevailing mechanism of the cortical bone loss in both sexes is increased osteoclastogenesis caused by estrogen deficiency; this is likely driven, at least in part, by mesenchymal/stromal cell-derived SDF1. Decreased osteoblastogenesis, owing in part to increased H2 O2, combined with increased osteoclastogenesis caused by aging mechanisms independent of estrogen deficiency, are the prevailing mechanisms of the loss of cortical bone with old age.

AB - Human and bovine group B streptococcus (GBS) isolates were serotyped and amounts of released N-acetylneuraminic acid from N-acetylneuraminyl-lactose by extracellular neuraminidase were colorimetrically assessed. According to serotyping by co-agglutination method, 30 of bovine GBS and 43 of human GBS could be serotyped (ST) by monospecific antisera coated with protein A. The remaining GBS strains were designated as nontypeable (NT). The released N-acetylneuraminic acid was determined in 90.9% of bovine GBS and 47.1% of human GBS isolates. The differences between the total bovine and human GBS isolates were statistically significant (p < 0.001). In comparison with detected N-acetylneuraminic acid level in bovine and human groups, significant decrease was observed in the bovine NT group according to increased human NT (p < 0.01) and bovine ST groups (p < 0.01). However, N-acetylneuraminic acid level in bovine ST and bovine total groups significantly (p < 0.001) increased with respect to the human ST group and human total group. Neuraminidase activity was detected more frequently in bovine GBS isolates. Considerable differentiations were observed between typeable and nontypeable isolates. PMID- 27714849 TI - Psychosocial or clinico-demographic factors related to neuropsychiatric symptoms in patients with Alzheimer's disease needing interventional treatment: analysis of the CATIE-AD study. AB - OBJECTIVE: This study sought to determine psychosocial and clinico-demographic factors related to each symptomatic cluster (i.e., aggressiveness, psychosis, apathy/eating problems, and emotion/disinhibition) of neuropsychiatric symptoms (NPSs) in patients with Alzheimer's disease (AD) needing interventional treatment against their agitation or psychotic symptoms. These clusters were classified from 12 Neuropsychiatric Inventory (NPI) subscores in our previous study using the Clinical Antipsychotic Trials of Intervention Effectiveness-Alzheimer's Disease (CATIE-AD) dataset. METHODS: Based on clinical data from 421 AD outpatients with agitation or psychotic symptoms needed interventional treatment enrolled in the CATIE-AD, we conducted logistic regression analyses to examine the relationships between each symptomatic cluster and three psychosocial (marital status, residence, and caregivers' burden) and nine clinico-demographic (age, gender, education year, general cognition, activity of daily living [ADL], general medical health, race, and intake of anti-dementia drugs or psychotropics) factors. RESULTS: While no factor contributed to aggressiveness, psychosis was associated with several clinico-demographic factors: female gender, non-Caucasian race, and lower cognitive function. Apathy/eating problems was associated with more severe caregiver burden, living in one's own home, lower ADL level, and male gender, while emotion/disinhibition was predicted by more severe caregiver burden, lower education level, not-married status, and younger age. CONCLUSIONS: Among the four NPS clusters, apathy/eating problems and emotion/disinhibition were associated with psychosocial as well as clinico-demographic factors in AD patients with psychotic symptoms or agitation needed interventional treatment.

PMID- 27714851 TI - Cynomolgus monkey model of interleukin-31-induced scratching depicts blockade of human interleukin-31 receptor A by a humanized monoclonal antibody. AB - Scratching is an important factor exacerbating skin lesions through the so-called itch-scratch cycle in atopic dermatitis (AD). In mice, interleukin (IL)-31 and its receptor IL-31 receptor A (IL-31RA) are known to play a critical role in pruritus and the pathogenesis of AD; however, study of their precise roles in primates is hindered by the low sequence homologies between primates and mice and the lack of direct evidence of itch sensation by IL-31 in primates. We showed that administration of cynomolgus IL-31 induces transient scratching behaviour in cynomolgus monkeys and by that were able to establish a monkey model of scratching. We then showed that a single subcutaneous injection of 1 mg/kg nemolizumab, a humanized anti-human IL-31RA monoclonal antibody that also neutralizes cynomolgus IL-31 signalling and shows a good pharmacokinetic profile in cynomolgus monkeys, suppressed the IL-31-induced scratching for about 2 months. These results suggest that the IL-31 axis and IL-31RA axis play as critical a role in the induction of scratching in primates as in mice and that the blockade of IL-31 signalling by an anti-human IL-31RA antibody is a promising therapeutic approach for treatment of AD. Nemolizumab is currently under investigation in clinical trials. PMID- 27714852 TI - Physical fitness and academic performance in youth: A systematic review. AB - Physical fitness (PF) is a construct of health- and skill-related attributes which have been associated with academic performance (AP) in youth. This study aimed to review the scientific evidence on the association among components of PF and AP in children and adolescents. A systematic review of articles using databases PubMed/Medline, ERIC, LILACS, SciELO, and Web of Science was undertaken. Cross-sectional and longitudinal studies examining the association between at least one component of PF and AP in children and adolescents, published between 1990 and June 2016, were included. Independent extraction of articles was carried out by the two authors using predefined data fields. From a total of 45 studies included, 25 report a positive association between components of PF with AP and 20 describe a single association between cardiorespiratory fitness (CRF) and AP. According to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines: 12 were classified as low, 32 as medium risk, and 1 as high risk of bias. Thirty-one studies reported a positive association between AP and CRF, six studies with muscular strength, three studies with flexibility, and seven studies reported a positive association between clustered of PF components and AP. The magnitude of the associations is weak to moderate (beta = 0.10-0.42 and odds = 1.01-4.14). There is strong evidence for a positive association between CRF and cluster of PF with AP in cross-sectional studies; and evidence from longitudinal studies for a positive association between cluster of PF and AP; the relationship between muscular strength and flexibility with AP remains uncertain.

PMID- 27714853 TI - Liver transplant recipients with portal vein thrombosis receiving an organ from a high-risk donor are at an increased risk for graft loss due to hepatic artery thrombosis. AB - We hypothesize that recipients with pretransplant portal vein thrombosis (PVT) receiving organs from high-risk donors (HRD) are at an increased risk of HAT. Data on all liver transplants in the United States from February 2002 to March 2015 were analyzed. Recipients were sorted into two groups: those with PVT and those without. HRDs were defined by donor risk index (DRI) >1.7. Multivariable logistic regression models were constructed to assess the independent risk factors for HAT with the resultant graft loss <=90 days from transplantation. A total of 60 404 candidates underwent liver transplantation; of those recipients, 623 (1.0%) had HAT, of which 66.0% (n = 411) received organs from HRDs compared with 49.3% (n = 29 473) in recipients without HAT (P < 0.001); 2250 (3.7%) recipients had pretransplantation PVT and received organs from HRDs. On adjusted multivariable analysis, PVT with a HRD organ was the most significant independent risk factor (OR 3.56, 95% CI 2.52-5.02, P < 0.001) for the development of HAT. Candidates with pretransplant PVT who receive an organ from a HRD are at the highest risk for postoperative HAT independent of other measurable factors. Recipients with pretransplant PVT would benefit from careful donor selection and possibly anticoagulation perioperatively. PMID- 27714855 TI - Role of carbohydrate in central fatigue: a systematic review. AB - Carbohydrate (CHO) depletion is linked to neuromuscular fatigue during exercise. While its role at peripheral level is relatively well understood, less is known about its impact centrally. The aim of this systematic review was to critically analyze the effects of CHO on central fatigue (CF) assessed by various neurophysiological techniques. Four databases were searched using PRISMA guidelines through February 2016. The inclusion criteria were: CHO as intervention against a placebo control, fatigue induced by prolonged exercise and assessed using neurophysiological measures [voluntary activation (VA), superimposed twitch (SIT), M-wave, electromyography], alongside maximal voluntary contraction (MVC). Seven papers were reviewed, where exercise duration lasted between 115 and 180 min. CHO improved exercise performance in three studies, whereby two of them attributed it to CF via attenuation of VA and SIT reductions, while the other indicated peripheral involvement via attenuation of M-wave reduction. Although a few studies suggest that CHO attenuates CF, data on its direct effects on neurophysiological outcome measures are limited and mixed. Generally, measures employed in these studies were inadequate to conclude central contribution to fatigue. Factors including the techniques used and the lack of controls render additional confounding factors to make definitive deductions. Future studies should employ consistent techniques and appropriate neurophysiological controls to distinguish CHO effect at central level. The use of pharmacological intervention should be incorporated to elucidate involvement of central mechanisms. PMID- 27714856 TI - High diversity of the T-cell receptor repertoire of tumor-infiltrating lymphocytes in basal cell carcinoma. AB - Whether specific T-cell clones are present in tumor infiltrating lymphocytes (TILs) in BCC is unknown. We employed deep sequencing of mRNA coding for the T cell receptor (TCR) chains alpha- and beta to characterize the repertoire of TILs in BCC. V and J gene-usage and CDR3 length were computed to determine the clonality of TCR and degree of overlap in TCR repertoires between skin resident T cells and TILs. We found high diversity of the TCR repertoire in BCC and control skin with random V-J gene usage and similar CDR3-length distribution. Lack of TCR repertoire restriction indicates absence of tumor-specific TIL clones in BCC. PMID- 27714857 TI - Depigmentation of alpha-melanocyte-stimulating hormone-treated melanoma cells by beta-mangostin is mediated by selective autophagy. AB - Melanogenesis is a key pathway for the regulation of skin pigmentation and the development of skin-lightening/skin-whitening drugs or cosmetics. In this study, we found that beta-mangostin from seedcases of Garcinia mangostana inhibited alpha-melanocyte-stimulating hormone (alpha-MSH)-mediated melanogenesis in B16F10 melanoma cells and a three-dimensional human skin model. beta-Mangostin significantly inhibited the protein level of tyrosinase induced by alpha-MSH in UPS (ubiquitin proteasome system)-independent and lysosome-dependent manner. The inhibition of autophagy by 3-methyladenine treatment or ATG5 knockdown effectively recovered premelanosome protein as well as tyrosinase degraded by the beta-mangostin treatment. However, rapamycin, a representative non-selective autophagy inducer, triggered autophagy in alpha-MSH-stimulated cells, which was characterized by a considerable decrease in p62, but it was unable to inhibit melanogenesis. Melanosome-engulfing autophagosomes were observed using transmission electron microscopy. Furthermore, previously formed melanin could be degraded effectively in an autophagy-dependent manner in beta-mangostin-treated cells. Taken together, our results suggest that beta-mangostin inhibits the melanogenesis induced by alpha-MSH via an autophagy-dependent mechanism, and thus, the depigmentation effect of beta-mangostin may depend on autophagy targeted at the melanosome rather than non-selective autophagy. PMID- 27714858 TI - Long-term consequences of vocal fold hemorrhage. AB - OBJECTIVES/HYPOTHESIS: To assess the long-term impact of vocal fold hemorrhage (VFH) on vocal function and health, and compare these parameters to those in similar patients who have not had VFH. STUDY DESIGN: Retrospective cohort study. METHODS: Patients with a history of VFH (N = 41) were characterized through a review of records and assessed by means of a survey for vocal health and professional functioning as well as the Voice Handicap Index-10 (VHI-10) and, if appropriate (n = 30, 73.2%), the Singing Voice Handicap Index (SVHI-10). They were compared to a group of demographically and occupationally similar patients without VFH (N = 25, 60.9%). Patients with multiple episodes of VFH (n = 9, 22.0%) were compared to patients with a single event. RESULTS: After a median of 41 months follow-up, patients with VFH had favorable vocal function assessment and low median VHI-10 and SVHI-10 scores (4 and 6, respectively), substantially similar to patients without VFH (VHI-10, P = .905 and SVHI 10, P =.991). The two groups showed similarly low rates of change in occupation (7.3%vs. 8.0%, P =.999). Patients with VFH were more likely to have missed days of work due to a voice problem. Analysis of patients with one versus multiple VFH episodes showed no differences, except patients with multiple episodes had significantly greater confidence in their ability to address future VFH. CONCLUSIONS: Contrary to commonly held belief, VFH appears to have no significant long-term impact on vocational stability, subjective voice quality, or perceptions of vocal function. Moreover, among those with VFH, recurrence seems only to diminish anxiety over this transient injury. LEVEL OF EVIDENCE: 4 Laryngoscope, 127:900-906, 2017. PMID- 27714859 TI - Evaluation of Basal Serum or Plasma Cortisol Concentrations for the Diagnosis of Hypoadrenocorticism in Dogs. AB - BACKGROUND: Previous studies that included limited numbers of affected dogs have suggested basal cortisol concentrations <=55 nmol/L (2 MUg/dL) are sensitive, but nonspecific, for a diagnosis of hypoadrenocorticism. A detailed assessment of the diagnostic utility of basal cortisol concentrations is warranted. HYPOTHESIS/OBJECTIVES: To evaluate the utility of basal cortisol concentrations for the diagnosis of hypoadrenocorticism in a large number of dogs, including those with and without serum electrolyte abnormalities. ANIMALS: Five hundred and twenty-two dogs, including 163 dogs with hypoadrenocorticism, 351 dogs with nonadrenal gland illness, and 8 dogs with equivocal results. METHODS: Retrospective study. Basal and post-ACTH cortisol concentrations and sodium and potassium concentrations were collected from medical records. A receiver operating characteristic (ROC) curve was constructed for basal cortisol concentrations by standard methodologies. Sensitivity, specificity, and predictive values were determined for various cut-points. RESULTS: The area under the ROC curve was 0.988 and was similarly excellent regardless of serum electrolyte concentrations. At the most discriminatory cut-point of 22 nmol/L (0.8 MUg/dL), sensitivity and specificity were 96.9 and 95.7%, respectively. A basal cortisol concentration of <=55 nmol/L (2 MUg/dL) resulted in a sensitivity of 99.4%. Conversely, a basal cortisol concentration of <=5.5 nmol/L (0.19 MUg/dL) resulted in a specificity of 99.1%. CONCLUSIONS AND CLINICAL IMPORTANCE: Similar to findings in previous studies, basal cortisol concentrations >55 nmol/L (2 MUg/dL) are useful in excluding a diagnosis of hypoadrenocorticism. Interestingly, excellent specificities and positive predictive values were observed at lower cut-point cortisol concentrations.

AB - BACKGROUND: The present study aimed to analyse the nutritional quality of childrens' breakfasts using data collected during a cross-sectional observational study on the prevalence of urinary osmolality in 529 French children aged 9-11 years. METHODS: Total nutrient intake, mean adequacy ratio (MAR), energy density and solid energy density were calculated from breakfast food and fluid nutritional composition. To identify the main qualitative breakfast patterns, each breakfast item was categorised into 15 solid and liquid food categories and a principal component analysis followed by a cluster analysis was performed. RESULTS: Only 9.8% included skipped breakfast. Breakfast provided, on average, 22.9% of the recommended daily energy intake and 24.7% of the mean adequacy ratio of 23 key nutrients. Four breakfast patterns were identified: 'Sweets breakfast' (40.0% of children), 'Traditional French breakfast' (27.2%), 'Ready-to-eat cereal (RTEC) + milk' (18.1%) and 'Dairy and juice breakfast' (9.5%). Nutritionally, the 'RTEC + milk' pattern was the most advantageous. Flavoured milk was the most frequently consumed food (50.5%) and the major component of the 'Traditional French breakfast'. CONCLUSIONS: Although breakfast provided a substantial contribution to a range of nutrients, opportunity for improvement, particularly to less nutrient breakfast patterns, should not be overlooked.

AB - Mechanically reinforced skin-electronics are presented by exploiting networked nanocomposite elastomers where high quality metal nanowires serve as conducting paths. Theoretical and experimental studies show that the established skin electronics exhibit superior mechanical enhancements against crack and delamination phenomena. Device applications include a class of biomedical devices that offers the ability of thermotherapeutic stimulation and electrophysiological monitoring, all via the skin. PMID- 27714862 TI - T-cell "induced-self" MHC class I/peptide complexes may enable "de novo" tolerance induction to neo-antigens occurring outside of the thymus: Lessons from the hair follicle. AB - The hair follicle (HF) epithelium can present self-antigens to cognate CD8+ T cells. These cells express periodically during the hair cycle arising or age related immunogenic proteins including HF-specific neo-antigens. We propose that IFN-gamma derived from the respective antigen-specific T cells spotting the particular self-peptides may thereby significantly induce and alter self-antigen presentation ("induced-self"). This induction, at first, may silence T cells, including neo-epitope-specific T cells. As the thymus cannot significantly recapitulate neo-epitopes evolving in the periphery, we propose that peripheral tissue-specific induction of MHC molecules presenting exactly these neo-epitopes by self-MHC/peptide-reactive CD8+ T cells is a key element of self-tolerance. Subsequently, however, the local perpetuation and modification of the same crosstalk in the context of HF immune privilege collapse can invite HF immunopathology, as typically seen in alopecia areata. This concept may essentially complement thymus-based regulation models of self/non-self discrimination beyond "missing-self" to the fine-tuned "induced-self" to ensure peripheral needs to maintain self-tolerance in the case of "danger" and any "alteration of self".

PMID- 27714867 TI - USDA Fresh Fruit and Vegetable Program Is More Effective in Town and Rural Schools Than Those in More Populated Communities. AB - BACKGROUND: We attempted to determine effects of the United States Department of Agriculture (USDA) Fresh Fruit and Vegetable Program (FFVP) on variety and frequency of fruit and vegetable intake by students in schools from different locales. METHODS: Data were derived from the 2011-2012 Indiana FFVP Student Survey completed by 4229 fourth-sixth graders. Effects were studied within 2 groups, 39 city and suburb schools, and 12 town and rural schools. Differences in students' responses over time to 2 items measuring variety and 10 items measuring fruit and vegetable intake frequency were determined with multilevel regression models. RESULTS: Town and rural students were 1.2 times more likely to eat different kinds of fruit (p = .04) and vegetables (p = .01) daily, and increased fruit (+1.0 time/day; p < .01) and vegetable intake frequency (+0.5 times/day; p = .03). City and suburb students increased fruit intake frequency (~0.8 times/day; p < .01) but not vegetable intake frequency or daily variety (p > .05). CONCLUSIONS: FFVP improved fruit and vegetable eating behaviors in the "town and rural" group, but was only partially effective in the "city and suburb" group. Strategies to implement FFVP may need to differ depending on school locale. PMID- 27714869 TI - Impact of an Education Intervention on Missouri K-12 School Disaster and Biological Event Preparedness. AB - BACKGROUND: A 2011 nationwide school pandemic preparedness study found schools to be deficient. We examined the impact of a school nurse educational intervention aimed at improving K-12 school biological event preparedness. METHODS: Missouri Association of School Nurses (MASN) members were e-mailed a survey link in fall 2013 (ie, preintervention), links to online education modules (ie, intervention) in late fall, and a postintervention survey link in spring, 2014. School biological event readiness was measured using 35 indicators, for a possible score range of 0-35. A paired t-test compared pre- to postintervention preparedness scores. RESULTS: A total of 133 school nurses (33.6% response rate) completed a survey; 35.3% of those (N = 47) completed both pre- and postintervention survey that could be matched. Pre- and postintervention preparedness scores ranged from 5 to 28.5 (x? = 13.3) and 6.5 to 25 (x? = 14.8), respectively. Postintervention scores were significantly higher than preintervention scores for those who watched at least 1 module (t = -2.3, p < .05). CONCLUSION: The education intervention was effective at improving school preparedness, though the impact was small. The education intervention needs to be reassessed, especially in regard to providing a longer intervention period. PMID- 27714868 TI - Predictors of Obesity in a US Sample of High School Adolescents With and Without Disabilities. AB - BACKGROUND: Childhood obesity is a major public health concern. Children with disabilities have a higher prevalence of obesity. OBJECTIVE: We examined factors associated with obesity within a cross-sectional study of US adolescents with and without disabilities. METHODS: Data were obtained from the 2011 Youth Risk Behavior Survey. Logistic regression models were fitted to assess effects of dietary habits, physical activity, and unhealthy weight control behaviors on obesity. Effect modification by disability status was examined. RESULTS: Twenty percent (1986 of 9775 participants) reported a disability. Adolescents with disabilities were more likely to be obese (odds ratio [OR] = 1.7; 95% confidence interval [CI]: 1.3-2.1) and have at least 1 unhealthy weight control behavior (OR = 2.0; 95% CI: 1.6-2.5), and were less likely to be physically active (OR = 0.5; 95% CI: 0.4-0.6). Lack of physical activity, increased television watching/video game playing, and unhealthy weight loss behaviors were significantly associated with obesity regardless of disability status (p-for-interaction >.05). CONCLUSIONS: Successful obesity interventions should target diet, physical activity, and weight control among adolescents with disabilities. Understanding barriers to healthier diet and physical activity for this population is critical to developing effective obesity prevention programs and reducing the prevalence of unhealthy weight control behaviors. PMID- 27714870 TI - Verbal Bullying Changes Among Students Following an Educational Intervention Using the Integrated Model for Behavior Change. AB - BACKGROUND: Bullying behavior in schools can lead to psychosocial problems. School-based interventions are important in raising student awareness, developing their skills and in planning to reduce bullying behavior. METHODS: A randomized controlled trial, using a school-based educational intervention to reduce verbal bullying, was conducted among grade 10 students in 16 urban and rural schools in KwaZulu-Natal, South Africa in 2013. Baseline and postintervention questionnaires, developed using the Integrated Model for Behavior Change theoretical model, were used to assess changes in verbal bullying. RESULTS: Postintervention there were reduced verbal bullying experiences. Improved social norms and awareness of verbal bullying were associated with reduced verbal bullying experiences and behavior. Although less likely to bully others verbally, girls were more likely to experience verbal bullying. Students with no living father were more likely to bully others verbally. CONCLUSIONS: The study findings indicate that a school-based intervention can positively impact on verbal bullying experiences and behavior. PMID- 27714871 TI - Explaining Disparities in Youth Aerobic Fitness and Body Mass Index: Relative Impact of Socioeconomic and Minority Status. AB - BACKGROUND: To advance research on youth fitness promotion it is important to understand factors that may explain the disparities in fitness. METHODS: We evaluated data from the FitnessGram NFL PLAY60 Partnership Project to examine school factors influencing aerobic capacity (AC) and body mass index (BMI) in schoolchildren. Individual observations for AC (157,971 students from 675 schools) and BMI (178,274 students from 630 schools) were aggregated to compute the percentage of students achieving the Healthy Fitness Zone (HFZ). We examined achievements using adjusted linear regression models with socioeconomic status (SES), minority status, region, enrollment, and grade as factors. RESULTS: The mean HFZ for AC and BMI were 51.6% and 56.9%, respectively. SES, minority status, and enrollment were all significantly associated with AC HFZ among boys, and SES and enrollment were significant predictors of AC HFZ in girls. SES and location were significantly related to BMI HFZ among boys but only SES significantly predicted BMI HFZ in girls. Schools with higher SES had higher AC and BMI HFZ achievements. CONCLUSIONS: SES was consistently associated with health-related fitness, independent of sex, but not minority status. PMID- 27714873 TI - Food Literacy at Secondary Schools in Australia. AB - BACKGROUND: Food literacy can encourage adolescents to develop healthy dietary patterns. This study examined home economics teachers' (HET) perspectives of the importance, curriculum, self-efficacy, and food environments regarding food literacy in secondary schools in Australia. METHODS: A 20-item cross-sectional survey was completed by 205 HETs. The survey focused on the importance of aspects of food literacy, HETs' self-efficacy, and attitudes toward food literacy and schools' food environments. Data were analyzed descriptively, and associations between participants' demographic characteristics and perceptions were investigated by chi-square analyses. RESULTS: HETs rated aspects of food literacy including preparing and cooking food, knowing about healthy foods and food safety and hygiene practices as very important. They indicated animal welfare, where food comes from, and plan and manage time for food shopping to be the least important aspects of food literacy. HETs reported that students' involvement in food literacy activities resulted in healthier diets and improved food practices, but the schools' food environments are not comprehensively supportive of food literacy. CONCLUSIONS: HETs report that food literacy is very important for adolescents to learn. The focus is more on microaspects in comparison to macroaspects of food literacy. Schools' food environments are ideally positioned to shape dietary intake of adolescents but their potential is not being realized. PMID- 27714872 TI - Socioeconomic Factors Influence Physical Activity and Sport in Quebec Schools. AB - BACKGROUND: School environments providing a wide selection of physical activities and sufficient facilities are both essential and formative to ensure young people adopt active lifestyles. We describe the association between school opportunities for physical activity and socioeconomic factors measured by low-income cutoff index, school size (number of students), and neighborhood population density. METHODS: A cross-sectional survey using a 2-stage stratified sampling method built a representative sample of 143 French-speaking public schools in Quebec, Canada. Self-administered questionnaires collected data describing the physical activities offered and schools' sports facilities. Descriptive and bivariate analyses were performed separately for primary and secondary schools. RESULTS: In primary schools, school size was positively associated with more intramural and extracurricular activities, more diverse interior facilities, and activities promoting active transportation. Low-income primary schools were more likely to offer a single gym. Low-income secondary schools offered lower diversity of intramural activities and fewer exterior sporting facilities. High-income secondary schools with a large school size provided a greater number of opportunities, larger infrastructures, and a wider selection of physical activities than smaller low-income schools. CONCLUSIONS: Results reveal an overall positive association between school availability of physical and sport activity and socioeconomic factors. PMID- 27714874 TI - The Role of Ethnicity in School-Based Obesity Intervention for School-Aged Children: A Pilot Evaluation. AB - BACKGROUND: Rates of obesity have risen disproportionately for ethnic minority youth in the United States. School-based programs may be the most comprehensive and cost-effective way to implement primary prevention in children. In this study we evaluated the effect of a school-based obesity prevention on the outcome of body mass index percentile (BMI%), with baseline weight class and ethnicity examined as moderators. METHODS: Participants (N = 125), ages 7-11 (56% female) from 4 urban, low-income, ethnic minority (58% black, 42% Latino) schools were recruited. Two schools received the Urban Initiatives Work to Play health intervention, and 2 demographically matched schools served as wait-list controls. RESULTS: Hierarchical multiple regression was used to analyze the independent and interactive effects of key variables on BMI%. An interaction between intervention status and ethnicity revealed Latino youth in the intervention had lower BMI% than those in the control group. Participation did not cause BMI% outcomes to decrease for black participants. CONCLUSIONS: The study demonstrates the intervention is effective, but that the effectiveness varies across ethnicity. Interventions can be made more efficient and cost-effective by targeting youth of a common ethnicity that has shown empirical responsiveness to certain program elements. PMID- 27714875 TI - Victims of Bullying and Tobacco Use Behaviors in Adolescents: Differences Between Bullied at School, Electronically, or Both. AB - BACKGROUND: Being a victim of bullying is associated with greater risk of youth substance use; however, research specifically examining whether tobacco use behaviors differ among adolescents who were bullied at school only, electronically only, or both at school and electronically is limited. METHODS: We examined the associations between being a victim of bullying (at school only, electronically only, or both at school and electronically) and use of tobacco products using data from the 2013 national Youth Risk Behavior Survey. RESULTS: Girls who were bullied both at school and electronically reported the highest odds of all tobacco use behaviors (ever use of cigarettes, current use of cigarettes, and current use of any tobacco product) as compared with girls who were not bullied after adjusting for covariates. Conversely, for boys, only the association between being bullied electronically only and ever use of cigarettes remained significant after adjusting for covariates. CONCLUSIONS: Results from this study indicate that electronic bullying may differentially influence the odds of tobacco use in high school students as compared with bullying that occurs at school only. Confirmation of these findings could inform interventions to reduce both bullying and tobacco use in high school. PMID- 27714876 TI - Two-Dimensional Cobalt-/Nickel-Based Oxide Nanosheets for High-Performance Sodium and Lithium Storage. AB - Two-dimensional (2D) nanomaterials are one of the most promising types of candidates for energy-storage applications due to confined thicknesses and high surface areas, which would play an essential role in enhanced reaction kinetics. Herein, a universal process that can be extended for scale up is developed to synthesise ultrathin cobalt-/nickel-based hydroxides and oxides. The sodium and lithium storage capabilities of Co3 O4 nanosheets are evaluated in detail. For sodium storage, the Co3 O4 nanosheets exhibit excellent rate capability (e.g., 179 mA h g-1 at 7.0 A g-1 and 150 mA h g-1 at 10.0 A g-1 ) and promising cycling performance (404 mA h g-1 after 100 cycles at 0.1 A g-1 ). Meanwhile, very impressive lithium storage performance is also achieved, which is maintained at 1029 mA h g-1 after 100 cycles at 0.2 A g-1 . NiO and NiCo2 O4 nanosheets are also successfully prepared through the same synthetic approach, and both deliver very encouraging lithium storage performances. In addition to rechargeable batteries, 2D cobalt-/nickel-based hydroxides and oxides are also anticipated to have great potential applications in supercapacitors, electrocatalysis and other energy-storage-/-conversion-related fields. PMID- 27714877 TI - Reversal of warfarin anticoagulation using prothrombin complex concentrate at 25 IU kg-1 : results of the RAPID study. AB - BACKGROUND: Real-world studies of the emergency reversal of warfarin using 4 factor prothrombin complex concentrate (PCC) report unwarranted delays. The delay to receiving PCC was >= 8 h in 46.7% of patients with warfarin-associated bleeding (PWAB) treated with a variable PCC dosing protocol in our retrospective audit. OBJECTIVE: To report the impact of a simplified PCC dosing protocol on the interval to reversal of anticoagulation. METHODS: We developed a PCC dosing protocol standardising the initial PCC dose and simplifying dosing calculations. Study end points were the proportion of PWAB achieving international normalised ratio (INR) <=1.5 and treated within 8 h of presentation, respectively. RESULTS: Of 17, 15 (88.2%) PWABs achieved a post-treatment INR <= 1.5; 14 of 17 (82.4%) PWABs were reversed within 8 h. Median intervals between triage and PCC request and PCC request and start of infusion (administration interval) were 126 min (range 39-520) and 30 min (range 5-100), respectively. Compared with the retrospective cohort, RAPID is associated with an improved administration interval (mean 37.7 vs 76 min, P = 0.031) and the proportion of PWABs treated within 30 min (58.8 vs 6.7%, P = 0.009). CONCLUSION: The RAPID protocol reduces unwarranted delays without compromising efficacy. PMID- 27714878 TI - Bifunctional Platinated Nanoparticles for Photoinduced Tumor Ablation.

PMID- 27714879 TI - Novel algorithm for management of acute epididymitis. AB - OBJECTIVES: To identify predictive factors for the severity of epididymitis and to develop an algorithm guiding decisions on how to manage patients with this disease. METHODS: A retrospective study was carried out on 160 epididymitis patients at Keio University Hospital. We classified cases into severe and non severe groups, and compared clinical findings at the first visit. Based on statistical analyses, we developed an algorithm for predicting severe cases. We validated the algorithm by applying it to an external cohort of 96 patients at Tokyo Medical Center. The efficacy of the algorithm was investigated by a decision curve analysis. RESULTS: A total of 19 patients (11.9%) had severe epididymitis. Patient characteristics including older age, previous history of diabetes mellitus and fever, as well as laboratory data including a higher white blood cell count, C-reactive protein level and blood urea nitrogen level were independently associated with severity. A predictive algorithm was created with the ability to classify epididymitis cases into three risk groups. In the Keio University Hospital cohort, 100%, 23.5%, and 3.4% of cases in the high-, intermediate-, and low-risk groups, respectively, became severe. The specificity of the algorithm for predicting severe epididymitis proved to be 100% in the Keio University Hospital cohort and 98.8% in the Tokyo Medical Center cohort. The decision curve analysis also showed the high efficacy of the algorithm. CONCLUSIONS: This algorithm might aid in decision-making for the clinical management of acute epididymitis.

PMID- 27714884 TI - Coding paediatric outpatient data to provide health planners with information on children with chronic conditions and disabilities. AB - AIM: In New Zealand, there is a paucity of information on children with chronic conditions and disabilities (CCD). One reason is that many are managed in hospital outpatients where diagnostic coding of health-care events does not occur. This study explores the feasibility of coding paediatric outpatient data to provide health planners with information on children with CCD. METHODS: Thirty seven clinicians from six District Health Boards (DHBs) trialled coding over 12 weeks. In five DHBs, the International Classification of Diseases and Related Health Problems, 10th Edition, Australian Modification (ICD-10-AM) and Systematised Nomenclature of Medicine Clinical Terms (SNOMED-CT) were trialled for 6 weeks each. In one DHB, ICD-10-AM was trialled for 12 weeks. A random sample (30%) of ICD-10-AM coded events were also coded by clinical coders. A mix of paper and electronic methods were used. RESULTS: In total 2,604 outpatient events were coded in ICD-10-AM and 693 in SNOMED-CT. Dual coding occurred for 770 (29.6%) ICD-10-AM events. Overall, 34% of ICD-10-AM and 40% of SNOMED-CT events were for developmental and behavioural disorders. Chronic medical conditions were also common. Clinicians were concerned about the workload impacts, particularly for paper-based methods. Coder's were concerned about clinician's adherence to coding guidelines and the poor quality of documentation in some notes. CONCLUSION: Coded outpatient data could provide planners with a rich source of information on children with CCD. However, coding is also resource intensive. Thus its costs need to be weighed against the costs of managing a much larger health budget using very limited information.

PMID- 27714883 TI - Characteristics of C-terminal, beta-amyloid peptide binding fragment of neuroprotective protease inhibitor, cystatin C. AB - Cystatin C originally identified as a cysteine proteases inhibitor has a broad spectrum of biological roles ranging from inhibition of extracellular cysteine protease activities, bone resorption, and modulation of inflammatory responses to stimulation of fibroblasts proliferation. There is an increasing number of evidence to suggest that human cystatin C (hCC) might play a protective role in the pathophysiology of sporadic Alzheimer's disease. In vivo and in vitro results well documented the association of hCC with Abeta and the hCC-induced inhibition of Abeta fibril formation. In our earlier work, using a combination of selective proteolytic methods and MS spectroscopy, C-terminal fragment hCC(101-117) was identified as the Abeta-binding region. The fragment of Abeta peptide responsible for the complex formation with hCC was found in the middle, highly hydrophobic part, Abeta(17-24). Structures and affinities of both Abeta and hCC binding sites were characterized by the enzyme-linked immunosorbent assay-like assay, by surface plasmon resonance, and by nano-ESI-FTICR MS of the hCC-Abeta-binding peptide complexes. In the in vitro inhibition studies, the binding cystatin sequence, hCC(101-117), revealed the highest relative inhibitory effect toward Abeta-fibril formation. Herein, we present further studies on molecular details of the hCC-Abeta complex. With Ala substitution, affinity experiments, and enzyme linked immunosorbent assay-like assays for the Abeta-binding fragment, hCC(101 117), and its variants, the importance of individual amino acid residues for the protein interaction was evaluated. The results were analyzed using hCC(101-117) nuclear magnetic resonance structural data with molecular dynamics calculations and molecular modeling of the complexes. The results point to conformational requirements and special importance of some amino acid residues for the protein interaction. The obtained results might be helpful for the design of low molecular compounds modulating the biological role of both proteins. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27714886 TI - Pharmacokinetic and Pharmacodynamic Interaction of Andrographolide and Standardized Extract of Andrographis paniculata (Nees) with Nabumetone in Wistar Rats. AB - The aim of the study was to investigate the herb-drug interaction of Andrographis paniculata Nees (Acanthaceae) and Andrographolide (AN) with nabumetone (NAB) in wistar rats. Pharmacokinetic and pharmacodynamic interactions were studied after co-administration of APE and AN with NAB in Wistar rats. In pharmacokinetic studies, significant decrease in Cmax, AUC0-t and AUC0-infinity of 6-MNA after co administration with pure AN and APE has been observed. Tmax of 6-MNA has been increased to 2 h from 1.5 h in AN + NAB treated group. Changes in mean residential time, clearance and volume of distribution of 6-MNA in APE + NAB treated group and AN + NAB treated group indicated interference of other components of APE other than AN. In pharmacodynamic study, significant decrease in antiarthritic activity of NAB on concomitant administration with APE and AN has been observed. The study concludes that NAB exhibits pharmacokinetic and pharmacodynamic interactions with APE and AN in rats thus alarms the concomitant use of herbal preparations containing APE and AN with NAB. Further study is needed to understand the mechanism and predict the herb-drug interaction in humans. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27714888 TI - Genetic variation of growth dynamics in maize (Zea mays L.) revealed through automated non-invasive phenotyping. AB - Hitherto, most quantitative trait loci of maize growth and biomass yield have been identified for a single time point, usually the final harvest stage. Through this approach cumulative effects are detected, without considering genetic factors causing phase-specific differences in growth rates. To assess the genetics of growth dynamics, we employed automated non-invasive phenotyping to monitor the plant sizes of 252 diverse maize inbred lines at 11 different developmental time points; 50 k SNP array genotype data were used for genome-wide association mapping and genomic selection. The heritability of biomass was estimated to be over 71%, and the average prediction accuracy amounted to 0.39. Using the individual time point data, 12 main effect marker-trait associations (MTAs) and six pairs of epistatic interactions were detected that displayed different patterns of expression at various developmental time points. A subset of them also showed significant effects on relative growth rates in different intervals. The detected MTAs jointly explained up to 12% of the total phenotypic variation, decreasing with developmental progression. Using non-parametric functional mapping and multivariate mapping approaches, four additional marker loci affecting growth dynamics were detected. Our results demonstrate that plant biomass accumulation is a complex trait governed by many small effect loci, most of which act at certain restricted developmental phases. This highlights the need for investigation of stage-specific growth affecting genes to elucidate important processes operating at different developmental phases.

PMID- 27714889 TI - COMPARISON BETWEEN PROTON MAGNETIC RESONANCE SPECTROSCOPY FINDINGS IN DOGS WITH TICK-BORNE ENCEPHALITIS AND CLINICALLY NORMAL DOGS. AB - In vivo diagnosis of tick-borne encephalitis is difficult due to high seroprevalence and rapid viral clearance, limiting detection of antibodies in blood and cerebrospinal fluid. Magnetic resonance imaging (MRI) characteristics of tick-borne encephalitis have been reported, however MRI studies can also be negative despite the presence of neurologic signs. Magnetic resonance spectroscopy (1 H MRS) is an imaging method that provides additional information about the metabolic characteristics of brain tissues. The purpose of this retrospective cross-sectional study was to describe brain metabolites using short echo time single-voxel 1 H MRS in dogs with confirmed tick-borne encephalitis and compare them with healthy dogs. Inclusion criteria for the affected dogs were neurological symptoms suggestive of tick-borne encephalitis, previous endemic stay and tick-bite, diagnostic quality brain MRI and 1 H MRS studies, and positive antibody titers or confirmation of tick-borne encephalitis with necropsy. Control dogs were 10, clinically normal beagles that had been used in a previous study. A total of six affected dogs met inclusion criteria. All dogs affected with tick-borne encephalitis had 1 H MRS metabolite concentration alterations versus control dogs. These changes included mild to moderate decreases in N-acetyl aspartate and creatine peaks, and mild increases in glutamate/glutamine peaks. No lactate or lipid signal was detected in any dog. Myoinositol and choline signals did not differ between affected and control dogs. In conclusion, findings supported the use of 1 H MRS as an adjunctive imaging method for dogs with suspected tick-borne encephalitis and inconclusive conventional MRI findings. PMID- 27714890 TI - Chronic odorant exposure upregulates acquisition of functional properties in cultured embryonic chick olfactory sensory neurons. AB - Neuronal development and differentiation is modulated by activity-dependent mechanisms that stimulate endogenous neurogenesis and differentiation to promote adaptive survival of the organism. Studies on bird odor imprinting have shown how sensory stimuli or environmental influences can affect neonatal behavior, presumably by remodeling the developing nervous system. It is unclear whether these changes originate from the sensory neurons themselves or from the brain. Thus, we attempted to address this by using an in vitro system to separate the peripheral neurons from their central connections. Olfactory neurons from embryonic day 17 Gallus domesticus chicks were isolated, cultured, and exposed to 100 uM amyl acetate or phenethyl alcohol in 12-hr bouts, alternated with periods of no-odor exposure. On days 4 and 5 in vitro, cells were immunostained for olfactory marker protein, neuron-specific tubulin, and olfactory GTP-binding protein, and tested for odorant sensitivity using calcium imaging. While odorant exposure did not result in a significant increase in the overall number of neurons, it promoted neuron differentiation: a larger proportion of odorant exposed cells expressed olfactory marker protein and the olfactory GTP-binding protein. When cell responsiveness was tested using calcium imaging, a greater proportion of odorant-exposed cells responded to stimulation with 100 uM amyl acetate or phenethyl alcohol. Thus, odorant exposure during development modulated the developmental trajectories of individual neurons, resulting in changes in protein expression associated with odorant signaling. This suggests that the neuronal changes in the periphery have an important contribution to the overall long-term functional changes associated with odor imprinting. (c) 2016 Wiley Periodicals, Inc. PMID- 27714891 TI - A Novel Approach to Treating CFS and Co-morbid Health Anxiety: A Case Study. AB - OBJECTIVES: Chronic Fatigue Syndrome (CFS) is a debilitating condition that affects 0.2-0.4% of the population. First-line treatments are Cognitive Behaviour Therapy or graded exercise therapy; however, these treatments yield only moderate effect sizes. Emerging research suggests that anxiety about health may be common in CFS. Health anxiety treatment models demonstrate good therapeutic outcomes; however, these models have yet to be applied to CFS. This paper describes the application of a novel cognitive behavioural approach to the treatment of both physical and anxiety related symptoms in a patient with CFS and, furthermore, presents a conceptual hypothesis regarding the mutually maintaining relationship between these two co-occurring conditions. DESIGN: A single-case design was used, with pre-data, post-data and follow-up data. The cognitive behavioural model of health anxiety was adapted and delivered as an eight-session intervention. The intervention was driven by an individualized formulation developed collaboratively with the patient. RESULTS: The application of this approach generated reliable and clinically significant reductions in physical and psychological symptoms, which were maintained at 12-month follow-up. The participant no longer fulfilled the criteria for CFS or health anxiety following eight treatment sessions. The treatment approach was found to be agreeable to the patient. All treatment hypotheses were supported. CONCLUSIONS: An adapted cognitive behavioural approach to treating CFS and health anxiety yields positive results and shows promise for application to the broader CFS population.

KEY PRACTITIONER MESSAGES: Chronic Fatigue Syndrome (CFS) is a debilitating condition that is difficult to treat successfully; first-line recommended treatments achieve only moderate effect sizes. Anxiety, particularly about health, is reported to be common in CFS. However, anxiety is not specifically targeted within treatment and may negatively influence outcome due to the potentially mutually maintaining nature of these complex conditions. The present study demonstrates that an integrated treatment approach designed to encompass physical and psychological symptoms yields reliable and clinically significant outcomes in 50% of time recommend for first line treatments. Results reflected non-case level status for both CFS and health anxiety at end of treatment, in addition to reductions across all clinical measures. This study demonstrates the fundamental importance of an individualized, rather than generic, treatment approach to complex cases; the 'meaning' of experience is a central tenet within a cognitive approach that should be reflected in treatment.

AB - BACKGROUND: Self-management is an important asset in helping older adults remain independent and in control for as long as possible. There is no reliable and valid measurement instrument to evaluate self-management behaviour of older adults. OBJECTIVE: This study aims to design a measurement instrument, that is the Partners in Health scale for older adults (PIH-OA), to assess self-management knowledge and behaviour of community-living older adults and to examine its psychometric properties in a Dutch context. METHODS/DESIGN: The original PIH scale was translated into Dutch and adapted to the context of community-living older adults, resulting in the PIH-OA. Data for 1127 participants (mean age 81.7, SD=4.5) from the Embrace study were used to assess the psychometric properties. RESULTS: Data fitted a three-factor model, covering the constructs Knowledge, Management and Coping, with good internal consistencies (Cronbach's alphas ranging from .77 to .84). Known groups validity was confirmed: no differences were found between gender, age and marital status groups, and differences were found between the education level and health status groups. Discriminant validity was confirmed by weak correlations between PIH-OA scales and scales evaluating "Perceived integrated care" and "Activities of daily living (ADL)" (r<.30), and a moderate correlation between the PIH-OA subscale "Coping" and the scale evaluating "ADL" (r=.41). CONCLUSION: The PIH-OA appears to be a reliable and valid measurement instrument for assessing the self-management knowledge and behaviour of older adults. This could help professionals provide tailored support to improve the well-being and independence of older adults.

AB - AIM: Infectious disease (ID) hospitalisation rates are increasing in New Zealand (NZ), especially in pre-school children, and Maori and Pacific people. We aimed to identify risk factors for ID hospitalisation in infancy within a birth cohort of NZ children, and to identify differences in risk factors between ethnic groups. METHODS: We investigated an established cohort of 6846 NZ children, born in 2009-2010, with linkage to a national data set of hospitalisations. We used multivariable logistic regression to obtain odds ratios (OR) for factors associated with ID hospitalisation in the first year of life, firstly for all children, and then separately for Maori or Pacific children. RESULTS: In the whole cohort, factors associated with ID hospitalisation were Maori (OR: 1.49, 95% CI: 1.17-1.89) or Pacific (2.51; 2.00-3.15) versus European maternal ethnicity, male gender (1.32; 1.13-1.55), low birthweight (1.94, 1.39-2.66), exclusive breastfeeding for <4 months (1.22, 1.04-1.43), maternal experience of health-care racism (1.60, 1.19-2.12), household deprivation (most vs. least deprived quintile of households (1.50, 1.12-2.02)), day-care attendance (1.43, 1.12-1.81) and maternal smoking (1.55, 1.26-1.91). Factors associated with ID hospitalisation for Maori infants were high household deprivation (2.16, 1.06 5.02) and maternal smoking (1.48, 1.02-2.14); and for Pacific infants were delayed immunisation (1.72, 1.23-2.38), maternal experience of health-care racism (2.20, 1.29-3.70) and maternal smoking (1.59, 1.10-2.29). CONCLUSIONS: Maori and Pacific children in NZ experience a high burden of ID hospitalisation. Some risk factors, for example maternal smoking, are shared, while others are ethnic specific. Interventions aimed at preventing ID hospitalisations should address both shared and ethnic-specific factors.

AB - During the process of aseptic loosening of prostheses, particulate wear debris induces a continuous inflammatory-like response resulting in the formation of a layer of fibrous peri-prosthetic tissue at the bone-prosthesis interface. The current treatment for loosening is revision surgery which is associated with a high-morbidity rate, especially in old patients. Therefore, less invasive alternatives are necessary. One approach could be to re-establish osseointegration of the prosthesis by inducing osteoblast differentiation in the peri-prosthetic tissue. Therefore, the aim of this study was to investigate the capacity of peri-prosthetic tissue cells to differentiate into the osteoblast lineage. Cells isolated from peri-prosthetic tissue samples (n = 22)-obtained during revision surgeries-were cultured under normal and several osteogenic culture conditions. Osteogenic differentiation was assessed by measurement of Alkaline Phosphatse (ALP), mineralization of the matrix and expression of several osteogenic genes. Cells cultured in osteogenic medium showed a significant increase in ALP staining (p = 0.024), mineralization of the matrix (p < 0.001) and ALP gene expression (p = 0.014) compared to normal culture medium. Addition of bone morphogenetic proteins (BMPs), a specific GSK3beta inhibitor (GIN) or a combination of BMP and GIN to osteogenic medium could not increase ALP staining, mineralization, and ALP gene expression. In one donor, addition of GIN was required to induce mineralization of the matrix. Overall, we observed a high inter-donor variability in response to osteogenic stimuli. In conclusion, peri prosthetic tissue cells, cultured under osteogenic conditions, can produce alkaline phosphatase and mineralized matrix, and therefore show characteristics of differentiation into the osteoblastic lineage.

AB - Research in recent years has extensively investigated the therapeutic efficacy of mesenchymal stromal cells in regenerative medicine for many neurodegenerative diseases at preclinical and clinical stages. However, the success rate of stem cell therapy remains less at translational phase. Lack of relevant animal models that potentially simulate the molecular etiology of human pathological symptoms might be a reason behind such poor clinical outcomes associated with stem cell therapy. Apparently, self-renewal and differentiation ability of mesenchymal stem cells may help to study the early developmental signaling pathways connected with the diseases, such as Alzheimer's disease, Amyotrophic lateral sclerosis (ALS), etc., at in vitro level. Cannabidiol, a non-psychotrophic cannabinoid, has been demonstrated as a potent anti-inflammatory and neuroprotective agent in neurological preclinical models. In the present study, we investigated the modulatory role of cannabidiol on genes associated with ALS using human gingiva derived mesenchymal stromal cells (hGMSCs) as an in vitro model system. Next generation transcriptomic sequencing analysis demonstrated considerable modifications in the expression of genes connected with ALS pathology, oxidative stress, mitochondrial dysfunction, and excitotoxicity in hGMSCs treated with cannabidiol. Our results suggest the efficacy of cannabidiol to delineate the unknown molecular pathways, which may underlie ALS pathology at an early stage using hGMSCs as a compelling in vitro system. J. Cell.

PMID- 27714896 TI - Comparing calculated free testosterone with total testosterone for screening and diagnosing late-onset hypogonadism in aged males: A cross-sectional study. AB - OBJECTIVE: The aim of this study is to compare calculated free testosterone (cFT) and total testosterone (T) in predicting late-onset hypogonadism (LOH) in middle aged and elderly males. METHODS: We surveyed a random sample of 608 males between the ages of 45 and 87 years from Shanghai, China. The Aging Male Symptoms (AMS) questionnaire and the Androgen Deficiency in Aging Male (ADAM) questionnaire were completed by the subjects. Testosterone (T), sex hormone-binding globulin (SHBG), albumin, and other blood biochemical indexes were measured in 332 males. The corresponding cFT was obtained using the Vermeulen formula and the correlations between T and cFT were analyzed by SPSS statistical software. RESULTS: Among the 332 males who underwent biochemical evaluation, 289 males (87.0%) was positively screened by the ADAM questionnaire and 232 males (69.9%) by the AMS questionnaire. As suggested by linear regression, cFT exhibited a negative correlation with age in both ADAM+ and AMS+ group, whereas T did not appear to have significant correlation with age. Besides, there were statistically significant differences in cFT (P<.001) in the AMS questionnaire. CONCLUSIONS: Calculated free testosterone levels are more reliable than T levels for diagnosing LOH in middle-aged and elderly males. PMID- 27714898 TI - Review of cytomegalovirus coinfection in HIV-infected individuals in Africa. AB - BACKGROUND: Cytomegalovirus (CMV) infection among HIV-infected individuals may cause end-organ disease, which is an AIDS-defining condition. Evidence from high income countries suggests that CMV may alter the outcome of HIV infection, other than causing end-organ diseases. We reviewed literature on HIV and CMV coinfection in Africa. METHODS: Systematic review of published studies on HIV and CMV coinfection in Africa using the PubMed database. RESULTS: High CMV seroprevalence was found throughout Africa, exceeding 90% in most populations. Retinitis, pneumonia, and colitis were the most commonly reported CMV manifestations in HIV-infected individuals. Among patients with pulmonary symptoms, the prevalence of CMV pneumonitis varied from 20% to over 60%, whereas CMV was found in 0% to 14% of patients with gastrointestinal manifestations. Cytomegalovirus retinitis was found in 0% to 2.6% of examined HIV-infected individuals. The diagnostics of CMV end-organ diseases were found complex and difficult to interpret in African settings. Cytomegalovirus viremia was correlated with significantly lower CD4 cell count and increase in activated and apoptosis vulnerable T-lymphocytes. Also, CMV coinfection was found to be associated with increased transmission and progression of HIV infection. Moreover, detectable CMV DNA was an independent predictor of HIV transmission and mortality among HIV-infected individuals. CONCLUSIONS: Cytomegalovirus is highly prevalent in Africa and a common cause of disease manifestations in HIV-infected individuals among all age groups. Cytomegalovirus coinfection in HIV-infected individuals in Africa is associated with increased transmission and mortality of HIV, but it is a neglected area of research. PMID- 27714897 TI - Development and Validation of a Novel Laboratory-Specific Correction Equation for Total Serum Calcium and Its Association With Mortality Among Hemodialysis Patients. AB - Conventional albumin-corrected calcium is inaccurate in predicting ionized calcium, and hidden hypercalcemia, characterized as high ionized calcium with normal total calcium, is associated with higher mortality in hemodialysis patients. By using a national cohort of hemodialysis patients in the Unites States, a novel laboratory-specific prediction equation composed of total calcium, albumin, and phosphorus was derived from 242 patients in the South Atlantic division (adjusted R2 = 0.80 versus 0.71 for the conventional equation) and then validated among 566 patients in the other divisions (adjusted R2 = 0.79 versus 0.68 for the conventional equation). Compared with the conventional equation, the novel equation showed a greater correlation with intact parathyroid hormone. Its relative performance against the conventional equation was consistent across subgroups based on medications related to calcium metabolism. The novel equation also had a higher sensitivity (57% versus 34%) and an equivalent specificity (99% versus 100%) against ionized hypercalcemia at a cut off value of 10.2 mg/dL. Sensitivity and specificity at 9.4 mg/dL was 94% and 76% (versus 87% and 82% for the conventional equation), respectively. A survival analysis in 87,779 incident hemodialysis patients showed that among patients who were categorized as having a high-normal calcium status (ie, >9.4 to 10.2 mg/dL) by the conventional equation, there appeared a trend toward higher adjusted mortality risk across higher calcium status defined according to the novel equation. Meanwhile, the mortality risk was consistent across calcium strata defined according to the conventional equation within the categories defined by the novel equation. In conclusion, in comparison to the conventional equation, a novel laboratory-specific correction equation derived for correction of total calcium performs significantly better in ascertaining hidden hypercalcemia in hemodialysis patients, and aids in identifying patients at higher risk for mortality.

AB - Advanced molecular electronic components remain vital for the next generation of miniaturized integrated circuits. Thus, much research effort has been devoted to the discovery of lossless molecular wires, for which the charge transport rate or conductivity is not attenuated with length in the tunneling regime. Herein, we report the synthesis and electrochemical interrogation of DNA-like molecular wires. We determine that the rate of electron transfer through these constructs is independent of their length and propose a plausible mechanism to explain our findings. The reported approach holds relevance for the development of high performance molecular electronic components and the fundamental study of charge transport phenomena in organic semiconductors. PMID- 27714901 TI - Fusaricidins from Paenibacillus polymyxa M-1, a family of lipohexapeptides of unusual complexity-a mass spectrometric study. AB - Paenibacillus polymyxa are rhizobacteria with a high potential to produce natural compounds of biotechnological and medical interest. Main products of P. polymyxa are fusaricidins, a large family of antifungal lipopeptides with a 15-guanidino-3 hydroxypentadecanoic acid (GHPD) as fatty acid side chain. We use the P. polymyxa strain M-1 as a model organism for the exploration of the biosynthetic potential of these rhizobacteria. Using matrix-assisted laser-desorption/ionization time-of flight mass spectrometry (MALDI-TOF MS) about 40 new fusaricidins were detected which were fractionated by reversed-phase (rp) HPLC. Their structure was determined by MALDI-LIFT-TOF/TOF fragment analysis. The dominant fragment in the product ion spectra of fusaricidins appeared at m/z 256.3, 284.3 and 312.4, respectively, indicating variations in their fatty acid part. Two new subfamilies of fusaricidins were introduced which contain guanidino-3-hydroxyhepta- and nonadecanoic acid as fatty acid constituents. Apparently, the end-standing guanidine group is not modified as shown by direct infusion nano-electrospray ionization mass spectrometry (nano-ESI MS). The results of this study suggest that advanced mass spectrometry is the method of choice for investigating natural compounds of unusual diversity, like fusaricidins.

AB - OBJECTIVE: HIV diagnosis and linkage to care are the main barriers in Africa to achieving the UNAIDS 90-90-90 targets. We assessed HIV-positive status awareness and linkage to care among survey participants in Chiradzulu District, Malawi. METHOD: Nested cohort study within a population-based survey of persons aged 15 59 years between February and May 2013. Participants were interviewed and tested for HIV (and CD4 if found HIV-positive) in their homes. Multivariable regression was used to determine factors associated with HIV-positive status awareness prior to the survey and subsequent linkage to care. RESULTS: Of 8277 individuals eligible for the survey, 7270 (87.8%) participated and were tested for HIV. The overall HIV prevalence was 17.0%. Among HIV-positive participants, 77.0% knew their status and 72.8% were in care. Women (adjusted odds ratio [aOR] 6.5, 95% CI 3.2-13.1) and older participants (40-59 vs. 15-29 years, aOR 10.1, 95% CI 4.0 25.9) were more likely to be aware of their positive status. Of those newly diagnosed, 47.5% were linked to care within 3 months. Linkage to care was higher among older participants (40-59 vs. 15-29, adjusted hazard ratio [aHR] 3.39, 95% CI 1.83-6.26), women (aHR 1.73, 95% CI 1.12-2.67) and those eligible for ART (aHR 1.61, 95% CI 1.03-2.52). CONCLUSIONS: In settings with high levels of HIV awareness, home-based testing remains an efficient strategy to diagnose and link to care. Men were less likely to be diagnosed, and when diagnosed to link to care, underscoring the need for a gender focus in order to achieve the 90-90-90 targets. PMID- 27714905 TI - Power-to-Syngas: An Enabling Technology for the Transition of the Energy System? AB - Power-to-X concepts promise a reduction of greenhouse gas emissions simultaneously guaranteeing a safe energy supply even at high share of renewable power generation, thus becoming a cornerstone of a sustainable energy system. Power-to-syngas, that is, the electrochemical conversion of steam and carbon dioxide with the use of renewably generated electricity to syngas for the production of synfuels and high-value chemicals, offers an efficient technology to couple different energy-intense sectors, such as "traffic and transportation" and "chemical industry". Syngas produced by co-electrolysis can thus be regarded as a key-enabling step for a transition of the energy system, which offers additionally features of CO2 -valorization and closed carbon cycles. Here, we discuss advantages and current limitations of low- and high-temperature co electrolysis. Advances in both fundamental understanding of the basic reaction schemes and stable high-performance materials are essential to further promote co electrolysis. PMID- 27714904 TI - Successful participation of patients in interprofessional team meetings: A qualitative study. AB - BACKGROUND: The number of people with multiple chronic conditions increases as a result of ageing. To deal with the complex health-care needs of these patients, it is important that health-care professionals collaborate in interprofessional teams. To deliver patient-centred care, it is often recommended to include the patient as a member of the team. OBJECTIVE: To gain more insight into how health care professionals and patients, who are used to participate in interprofessional team meetings, experience and organize patient participation in the team meetings. METHODS: A qualitative study including observations of meetings (n=8), followed by semi-structured interviews with participating health-care professionals (n=8), patients and/or relatives (n=11). Professionals and patients were asked about their experiences of patient participation immediately after the team meetings. Results from both observations and interviews were analysed using content analysis. RESULTS: The findings show a variety of influencing factors related to patient participation that can be divided into five categories: (i) structure and task distribution, (ii) group composition, (iii) relationship between professionals and patients or relatives, (iv) patients' characteristics and (v) the purpose of the meeting. CONCLUSION: Patient participation during team meetings was appreciated by professionals and patients. A tailored approach to patient involvement during team meetings is preferable. When considering the presence of patients in team meetings, it is recommended to pay attention to patients' willingness and ability to participate, and the necessary information shared before the meeting. Participating patients seem to appreciate support and preparation for the meeting. PMID- 27714903 TI - Risk factors for ocular surface squamous neoplasia in Kenya: a case-control study. AB - OBJECTIVE: To determine modifiable risk factors of ocular surface squamous neoplasia (OSSN) in Kenya using disease-free controls. METHODS: Adults with conjunctival lesions were recruited at four eye care centres in Kenya and underwent excision biopsy. An equal number of controls having surgery for conditions not affecting the conjunctiva and unrelated to ultraviolet light were group-matched to cases by age group, sex and eye care centre. Associations of risk factors with OSSN were evaluated using multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs). Continuous variables were compared using the t-test or the Wilcoxon-Mann-Whitney U-test depending on their distribution. RESULTS: A total of 131 cases and 131 controls were recruited. About two-thirds of participants were female, and the mean age of cases and controls was 42.1 years and 43.3 years, respectively. Risk factors for OSSN were HIV infection without antiretroviral therapy (ART) use (OR = 48.42; 95% CI: 7.73-303.31) and with ART use (OR = 19.16; 95% CI: 6.60-55.57), longer duration of exposure to the sun in the main occupation (6.9 h/day vs. 4.6 h/day, OR = 1.24; 95% CI: 1.10-1.40) and a history of allergic conjunctivitis (OR = 74.61; 95% CI: 8.08-688.91). Wearing hats was protective (OR = 0.22; 95% CI: 0.07 0.63). CONCLUSION: Measures to prevent and control HIV, reduce sun exposure such as wearing hats and control allergic conjunctivitis are recommended. PMID- 27714906 TI - Retrospective evaluation of blood copper stable isotopes ratio 65 Cu/63 Cu as a biomarker of cancer in dogs. AB - Previous studies in humans with breast, colorectal or liver cancer showed that neoplasia was associated with a modification of the blood ratio between 65 Cu and 63 Cu (?Cu). The aim of the present study was to compare the blood ?Cu of dogs with cancer to healthy controls or dogs with non-oncologic disease. One hundred and seventeen dogs were included in the study (35 dogs with cancer, 33 dogs with non-neoplastic disease, and 49 healthy controls). The ?Cu of dogs with cancer was significantly lower than the ratio of healthy controls (P < 0.0001) but not significantly different from dogs with non-oncologic disease. Six dogs with lymphoma were also evaluated after they achieved clinical remission and five out of six had an increase of ?Cu. Further studies are warranted but these results suggest that ?Cu could help in the diagnosis of cancer in a controlled clinical context, and may be a potential biomarker for the follow-up of cancer.

PMID- 27714907 TI - The use and modification of injury prevention exercises by professional youth soccer teams. AB - The efficacy of injury prevention exercise programs (IPEPs) for amateur youth soccer has been established, but little is known about their adaptability to other soccer populations. This study aimed to assess the use of individual injury prevention exercises by professional youth soccer teams, against the industry standard, FIFA 11+ program. Four teams' chosen IPEPs were observed across one season and documented on a standardized form. The use of each FIFA 11+ exercise was coded as "performed", "performed modified" or "not performed". The proportion of the 160 observed sessions containing each individual exercise was calculated. Staff provided reasons for their use and modification of FIFA 11+ exercises. On average, individual FIFA 11+ exercises were conducted in original form in 12% of the sessions (range 0-33%), and in modified form in 28% of sessions (range 2 62%). The five most frequently observed exercises, in either original or modified form, were "bench" (72%), "squats" (69%), "running straight" (68%), "single-leg stance" (66%), and "sideways bench" (64%). Staff modified exercises to add variation, progression, and individualization, and to align with specific training formats and goals. Professional youth soccer teams often use injury prevention exercises similar to those in the FIFA 11+, but tailor them considerably to fit their implementation context. PMID- 27714910 TI - Changes in leisure-time physical activity and physical and mental health functioning: a follow-up study. AB - Functioning will be an increasingly important issue in Finland over the coming decades as the proportion of the population aged 65 and older is growing significantly. However, the associations between changes in physical activity and subsequent health functioning are poorly understood. The aim of this study was to examine how changes in physical activity relate to concurrent and prospective levels of health functioning. Cohort data from the Helsinki Health Study were used. Phase 1 (n = 8960, response rate 67%, 80% women) was conducted among 40- to 60-year-old employees of the City of Helsinki in 2000-2002, phase 2 in 2007 (n = 7332, response rate 83%), and phase 3 in 2012 (n = 6814, response rate 79%). Linear mixed models were used as the main statistical method. Increasing physical activity was associated with higher concurrent and prospective levels of physical health functioning, whereas decreasing activity was associated with lower levels of physical health functioning. The associations were stronger with physical than with mental health functioning. Promoting physical activity among aging people may help to maintain their level of health functioning. PMID- 27714909 TI - Influence of altitude on local adaptation in upland tree species from central Argentina. AB - Steep climatic gradients boost morphological and physiological adjustments in plants, with consequences on performance. The three principal woody species of the Sierras Grandes Mountains of central Argentina have marked differences in sapling performance along their altitudinal distribution. We hypothesize that the steep gradient of climatic conditions across the species' altitudinal distribution promotes trait differences between populations of different altitudes that are inherited by the following generation. Seeds from different altitudes were exposed to three temperature regimes to assess differential germination responses. Saplings were then transplanted to a greenhouse to assess possible variations in attributes and performance after 18 months. The three species showed differences in germination responses to temperature among altitudes and/or in sapling attributes and performance. In Maytenus boaria and Escallonia cordobensis, germination success was higher under high temperatures for the highest-altitude, whereas lower temperatures boosted germination of the lowest altitudes. Polylepis australis showed no differences in germination among temperature treatments. In the greenhouse, saplings of the three species from intermediate altitudes showed high performance, whereas the upper and lower populations seemed to be adjusted to tolerating more stressful conditions (i.e., lower temperatures at the upper end and water stress at the lower end), showing lower performance toward both altitudinal limits. These patterns agree with those described for saplings growing under field conditions, suggesting adjustments in response to environmental changes undergone by populations along the altitudinal range. The marked adjustments of populations to the local environment suggest a potentially high impact of climatic change on species distribution. PMID- 27714911 TI - Effects of group sports on health-related physical fitness of overweight youth: A systematic review and meta-analysis. AB - Group sports interventions have been developed to improve health-related physical fitness of overweight/obese youth. However, its benefits are not systematically documented. This study synthesizes the evidence about the effects of group sports on health-related physical fitness of overweight/obese youth. Pubmed, Web of Knowledge, Scopus, Medline, CINAHL, SportDiscus, and Academic Search Complete were searched in February 2016. Studies assessing the effects of group sports on body composition, cardiorespiratory endurance, muscle strength, flexibility, and neuromotor fitness of overweight/obese youth (aged <18 years) were included. Effect sizes (ES) were calculated with Cohen's d and its 95% confidence intervals (CI). Improvements were found in (i) body composition - percentage of fat body mass (pooled ES = 0.67; 95% CI = 0.24-1.10) and waist circumference (ES = 0.69; P = 0.004); (ii) cardiorespiratory endurance - peak oxygen consumption (pooled ES = 0.53; 95% CI = 0.13-0.92) and (iii) muscle strength - hand grip strength (ES = 0.72; P = 0.003). No significant effects were found for body mass index (pooled ES = 0.27; 95% CI = -0.14 to 0.69), percentage of lean body mass (ES = 0.01; P > 0.05), maximal power output (ES from 0 to 0.06; P > 0.05), sit-and-reach test (pooled ES = 0.26; 95% CI = -0.16 to 0.68) and agility test (ES = 0; P = 0.48). Group sports improve body composition, cardiorespiratory endurance, and hand grip strength of overweight/obese youth. Flexibility and neuromotor fitness do not seem to change following group sports.

PMID- 27714914 TI - A pilot study of potential brain donor satisfaction and attitudes towards telephone assessment. AB - OBJECTIVE: Test the feasibility of assessing cognition, psychiatric symptoms and daily living skills of potential brain donors by telephone and compare satisfaction and attitudes across telephone and face-to-face assessment. METHOD: Data were collected from 108 healthy participants from the Brains for Dementia Research cohort. Purposive sampling was used to assess feasibility and a randomised control trial design compared satisfaction and attitudes towards telephone and face-to-face assessment. Non-parametric tests were conducted to compare groups, and logistic regression was performed to assess the relationship between satisfaction and participant characteristics. RESULTS: Of the 80 participants offered telephone assessment, 67 (83.8%) agreed, 2 (2.5%) had a significant hearing impairment, 4 (5.0%) had potential memory problems and 7 (8.7%) declined. On average, telephone assessments lasted 38 min and duration was negatively associated with Telephone Interview of Cognitive Status-Modified scores (p = 0.001) and positively associated with age (p = 0.040), Neuropsychiatric Inventory scores (p = 0.019), Geriatric Depression Scale (p = 0.035) and Global Deterioration Scale (p = 0.022). Satisfaction was high in respect to organisational and personal aspects; ratings did not differ significantly across telephone and face-to-face assessment groups and were not related to socio-demographic characteristics. Participants undergoing telephone assessment were significantly more likely to hold positive attitudes towards this mode of assessment. CONCLUSIONS: Telephone assessment is feasible, time-efficient and acceptable to healthy, potential brain donors. When used with other assessment modes and within the context of established contact, telephone assessment offers greater flexibility to researchers and participants and represents an effective mechanism for overcoming the challenges of growing, ageing cohorts and uncertain resources.

An accompanying article by Garzorz-Stark et al. show how these tools could improve the classification of skin inflammatory diseases now based on clinical and pathological features. At last, the final aim of these tools is to predict treatment response in a patient. The utility of "precision" or personalized medicine in cutaneous inflammatory diseases could join the furrow drawn in cancer.

Infestation of these plants placed at a field site with moderate levels of Asian citrus psyllid (ACP) was monitored for 14 weeks following treatments, and insecticide residues in leaf tissue were quantified using enzyme-linked immunosorbent assay (ELISA). Bioassays were conducted using leaves harvested on various dates post-treatment to compare the efficacies of residues against adult ACP. RESULTS: Residues of the three neonicotinoids were detected in leaf tissues within 1 week after treatment. Peak concentrations established at 1 week for imidacloprid and dinotefuran and at 2 weeks for thiamethoxam. Imidacloprid and thiamethoxam outperformed the control and dinotefuran treatments at protecting trees from infestations by ACP eggs and nymphs. For a given insecticide concentration in leaf tissue, thiamethoxam induced the highest mortality of the three insecticides, and dinotefuran was the least toxic. CONCLUSION: If the time needed to achieve effective thresholds of a systemic neonicotinoid is known, treatments at production facilities could be scheduled that would minimize unnecessary post-treatment holding periods and ensure maximum retention of effective concentrations after the plants have shipped to retail outlets. The rapid uptake of the insecticides and retention at effective concentrations in containerized citrus suggest that the current 30 day post-treatment shipping restriction from production facilities to retail outlets outside of quarantine could be shortened to 14 days. Thiamethoxam should be added to the list of approved nursery treatments. (c) 2016 Society of Chemical Industry.

AB - Huntington's disease (HD) is associated with risk for developing psychiatric symptoms. Vulnerability or resilience to psychiatric symptoms may be associated with personality traits. This exploratory study, aimed to investigate personality traits in a large cohort of HD carriers and at risk gene-expansion negative individuals (HD non-carriers), exploring whether carrying the HD gene or growing up in an HD family influences personality traits. Forty-seven HD carriers, Thirty nine HD non-carriers, and 121 healthy controls answered the Danish version of the revised NEO personality inventory. Comparisons between HD carriers and HD non carriers were mostly non-significant but the combined group of HD carriers and non-carriers showed significantly higher scores on the facets: "hostility," "assertiveness," and "activity" and on the trait "Conscientiousness" relative to controls, "Conscientiousness" have been associated with resilience to psychiatric symptoms. Twelve HD carriers and non-carriers were classified as depressed and showed significantly lower scores on "Extraversion" and "Conscientiousness" and significantly higher scores on "Neuroticism," which are associated with vulnerability to psychiatric symptoms. Our findings suggest that, there is no direct effect of the HD gene on personality traits, but that personality assessment may be relevant to use when identifying individuals from HD families who are vulnerable to develop psychiatric symptoms.

AB - As an early career investigator, starting one's own research group is often the next important step towards a tenured academic position. As a clinical epidemiologist who has recently moved from Leiden in the Netherlands, where I obtained my PhD, to become a group leader in Berlin, Germany, I have been through this transition. In the first few months as a group leader, I encountered several new situations, as might be expected for any other novice group leader. This paper, which describes my own experiences of dealing with these new situations, may help other early career researchers in their preparations and efforts to find their own approach to handling the new situations typically encountered as a group leader. PMID- 27714920 TI - Familial Gordon syndrome associated with a PIEZO2 mutation. AB - Gordon syndrome or distal arthrogryposis type 3 is a rare autosomal dominant disorder characterized by contractures of upper and lower limbs. It is distinguishable from other forms of distal arthrogryposis by cleft palate and short stature. Recently, Gordon syndrome has been associated to heterozygous mutations in the piezo-type mechanosensitive ion channel component 2 gene (PIEZO2). Different mutations of this gene also cause distal arthrogryposis type 5 and Marden-Walker syndrome. Dysfunction of this ion channel provides pleiotropic effects on joints, ocular muscles, and bone development. Here, we present a family with three affected individuals exhibiting multiple contractures (metacarpo-phalangeal and interphalangeal joints as well as elbow, shoulder, knee, and ankle joints), clubfeet, short stature, bifid uvula/cleft palate, and a distinct facial phenotype including ptosis. In addition, mild intellectual disability and delay in psychomotor development are obvious. The multigenerational phenotypic spectrum of Gordon syndrome is present in the 37 year-old father, his 4-year-old son and a male neonate showing typical signs of arthrogryposis in the prenatal ultrasound examination already seen at 13 week of gestation. In all affected family members, we identified the PIEZO2 mutation c.8057G>A (p.Arg2686His) by Sanger sequencing. Our analysis indicated that mild delay in psychomotor development and intellectual disability could be part of the phenotypic spectrum of Gordon syndrome. (c) 2016 Wiley Periodicals, Inc. PMID- 27714919 TI - The association of anti-platelet factor 4/heparin antibodies with early and delayed thromboembolism after cardiac surgery. AB - : Essentials We evaluated antibody status, thromboembolism and survival after cardiac surgery. Positive antibody tests are common - over 50% are seropositive at 30 days. Seropositivity did not increase thromboembolism or impair survival after cardiac surgery. Results show heparin induced thrombocytopenia antibody screening after surgery is not warranted. SUMMARY: Background Heparin-induced thrombocytopenia (HIT) is a prothrombotic response to heparin therapy with platelet-activating, anti-platelet factor 4 (PF4)/heparin antibodies leading to thrombocytopenia associated with thromboembolism. Objective We tested the hypothesis that anti-PF4/heparin antibodies are associated with thromboembolism after cardiac surgery. Methods This multicenter, prospective cohort study collected laboratory and clinical data up to 30 days after surgery and longer term clinical follow-up data. The primary outcome variable combined new arterial or venous thromboembolic complications (TECs) with all-cause death until 90 days after surgery. Laboratory analyses included platelet counts and anti-PF4/heparin antibody titers (GTI ELISA), with a confirmatory excess heparin step and serotonin release assay. Chi-square testing was used to test the relationship between our outcome and HIT antibody seropositivity. Results Initially, 1021 patients were enrolled between August 2006 and May 2009, and follow-up was completed in December 2014. Seropositivity defined by OD > 0.4 was common, being almost 20% preoperatively, > 30% by discharge, and > 60% by day 30. Death (1.7% within 30 days) or TECs (69 in total) were more likely if the partient was seronegative (OD < 0.4), but positivity defined by OD > 1.0 or including an excess heparin confirmatory step resulted in equal incidence of death or TECs, whether the patient was seronegative or seropositive. Incorporating the serotonin release assay for platelet-activating antibodies did not alter these findings. Conclusions Seropositivity for anti-PF4/heparin antibodies does not increase the risk of death or thromboembolism after cardiac surgery. Screening is not indicated, and seropositivity should only be interpreted in the context of clinical evidence for HIT. TRIAL REGISTRATION: Duke IRB Protocol #00010736. PMID- 27714921 TI - A Counterion-Directed Approach to the Diels-Alder Paradigm: Cascade Synthesis of Tricyclic Fused Cyclopropanes. AB - An approach to the intramolecular Diels-Alder reaction has led to a cascade synthesis of complex carbocycles composed of three fused rings and up to five stereocenters with complete stereocontrol. Computational analysis reveals that the reaction proceeds by a Michael/Michael/cyclopropanation/epimerization cascade in which size and coordination of the counterion is key.

AB - Adipose tissue inflammation and macrophage polarization are tightly associated with the development of obesity-associated insulin resistance. Our previous studies have demonstrated the triterpenoids-enriched extract from the aerial parts of Salvia miltiorrhiza (TTE) could significantly improve atherosclerosis in LDLR-/- mice. However, its molecular mechanisms of TTE ameliorating insulin resistance remain unclear. In the present study, obesity model with insulin resistance induced by feeding high-fat diet (HFD) was established. Dietary TTE attenuated hyperlipidemia, improved glucose intolerance in mice and mediated the activation of IRS-1/PI3K/Akt insulin signaling pathway. Meanwhile, dietary TTE also attenuated macrophage infiltrations into adipose tissue and modified the phenotype ratio of M1/M2 macrophages. Furthermore, our results showed that TTE regulated the polarization of macrophages partly via adenosine monophosphate activated kinase (AMPK). Taken together, these findings suggested that TTE has a potential clinical utility in improving insulin resistance. Its mechanisms might be contributed to its beneficial effects on macrophage polarization via AMPK. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27714923 TI - The evolution of the avian bill as a thermoregulatory organ. AB - The avian bill is a textbook example of how evolution shapes morphology in response to changing environments. Bills of seed-specialist finches in particular have been the focus of intense study demonstrating how climatic fluctuations acting on food availability drive bill size and shape. The avian bill also plays an important but under-appreciated role in body temperature regulation, and therefore in energetics. Birds are endothermic and rely on numerous mechanisms for balancing internal heat production with biophysical constraints of the environment. The bill is highly vascularised and heat exchange with the environment can vary substantially, ranging from around 2% to as high as 400% of basal heat production in certain species. This heat exchange may impact how birds respond to heat stress, substitute for evaporative water loss at elevated temperatures or environments of altered water availability, or be an energetic liability at low environmental temperatures. As a result, in numerous taxa, there is evidence for a positive association between bill size and environmental temperatures, both within and among species. Therefore, bill size is both developmentally flexible and evolutionarily adaptive in response to temperature. Understanding the evolution of variation in bill size however, requires explanations of all potential mechanisms. The purpose of this review, therefore, is to promote a greater understanding of the role of temperature on shaping bill size over spatial gradients as well as developmental, seasonal, and evolutionary timescales.

AB - Ionic liquids (ILs) are new, innovative ionic solvents with rich physicochemical properties and intriguing pre-organized solvent structures; these materials offer great potential to impact across versatile areas of scientific research, for example, synthetic inorganic chemistry. Recent use of ILs as precursors, templates, and solvents has led to inorganic materials with tailored sizes, dimensionalities, morphologies, and functionalities that are difficult to obtain, or even not accessible, by using conventional solvents. Poly(ionic liquid)s (PILs) polymerized from IL monomers also raise the prospect of modifying nucleation, growth, and crystallization of inorganic objects, shedding light on the synthesis of a wide range of new materials. Here we survey recent key progress in using ILs and PILs in the field of synthetic inorganic chemistry. As well as highlighting the unique features of ILs and PILs that enable advanced synthesis, the effects of adding other solvents to the final products, along with the emerging applications of the created inorganic materials will be discussed. We finally provide an outlook on several development opportunities that could lead to new advancements of this exciting research field.

AB - INTRODUCTION: This work aims to explore radiation doses delivered in screening mammography in Australia, with a focus on whether compressed breast thickness should be used as a guide when determining patient derived diagnostic reference levels (DRLs). METHODS: Anonymized mammograms (52,405) were retrieved from a central database, and DICOM headers were extracted using third party software. Women with breast implants, breast thicknesses outside 20-110 mm and images with incomplete exposure or quality assurance (QA) data were excluded. Exposure and QA information were utilized to calculate the mean glandular dose (MGD) for 45,054 mammograms from 61 units representing four manufacturers using previously well established methods. The 75th and 95th percentiles were calculated across median image MGDs obtained for all included data and according to specific compressed breast thickness ranges. RESULTS: The overall median image MGD, minimum, maximum were: 1.39, 0.19 and 10.00 mGy, respectively, the 75th and 95th percentiles across all units' median image MGD for 60 +/- 5 mm compressed breast thickness were 2.06 and 2.69 mGy respectively. Median MGDs, minimum, maximum, 75th and 95th percentiles were presented for nine compressed breast thickness ranges, DRLs for NSW are suggested for the compressed breast thickness range of 60 +/- 5 mm for the whole study and three detector technologies CR, DR, and photon counting to be 2.06, 2.22, 2.04 and 0.79 mGy respectively. CONCLUSION: MGD is dependent upon compressed breast thickness and it is recommended that DRL values should be specific to compressed breast thickness and image detector technology.

AB - The majority of research examining the barriers to breastfeeding focuses on the physical challenges faced by mothers rather than the risks of encountering negative emotional and practical feeding experiences. We aimed to quantify the emotional and practical experiences of the overall sample of breastfeeding mothers and identify the differences in the emotional and practical experiences of exclusively breastfeeding mothers and combination feeding mothers, by feeding type and intention. Eight hundred forty-five mothers with infants up to 26 weeks of age and who had initiated breastfeeding were recruited through relevant social media via advertisements providing a link to an online survey. Predictors of emotional experiences included guilt, stigma, satisfaction with feeding method, and the need to defend themselves due to infant feeding choices. Practical predictors included perceived support from health professionals, main sources of infant feeding information, and respect from their everyday environment, workplace, and when breastfeeding in public. Current feeding type and prenatal feeding intention. In the overall sample, 15% of the mothers reported feeling guilty, 38% stigmatized, and 55% felt the need to defend their feeding choice. Binary logit models revealed that guilt and dissatisfaction were directly associated with feeding type, being higher when supplementing with formula. No associations with feeding intention were identified. This study demonstrates a link between current breastfeeding promotion strategies and the emotional state of breastfeeding mothers who supplement with formula to any extent. To minimize the negative impact on maternal well-being, it is important that future recommendations recognize the challenges that exclusive breastfeeding brings and provide a more balanced and realistic target for mothers. PMID- 27714928 TI - Bilberry: Chemical Profiling, in Vitro and in Vivo Antioxidant Activity and Nephroprotective Effect against Gentamicin Toxicity in Rats. AB - We assessed possible protective effect of bilberry diet in rat model of nephrotoxicity. In vivo and in vitro antioxidant activity and chemical profiling of this functional food was performed. With aid of HPLC-DAD and spectrophotometric method, 15 individual anthocyanins were quantified alongside total tannin, phenylpropanoid, and anthocyanin content. The study was conducted on four groups of rats: control, treated with only gentamicin, treated with only bilberry, and treated with both gentamicin and bilberry. Kidney function was evaluated by tracking urea and creatinine. Morphology of renal tissue and its changes were recorded pathohistologically and quantified morphometrically. Bilberry (100 mg/kg daily) showed strong nephroprotective effect against gentamicin toxicity in rats (as shown through MDA, AOPP, and catalase levels). In conclusion, the demonstrated protective activity of bilberry extract matched well with the assessed in vivo and in vitro antioxidant activity as well as with its polyphenolic content, particularly with high anthocyanin levels.

AB - Vitamin D, in addition to its classical functions in bone homeostasis, has a modulatory and regulatory role in multiple processes, including host defense, inflammation, immunity, and epithelial repair. Patients with respiratory disease are frequently deficient in vitamin D, implying that supplementation might provide significant benefit to these patients. Respiratory viral infections are common and are the main trigger of acute exacerbations and hospitalization in children and adults with asthma and other airways diseases. Respiratory monocytes/macrophages and epithelial cells constitutively express the vitamin D receptor. Vitamin D, acting through this receptor, may be important in protection against respiratory infections. Whether the in vitro findings can be translated into a substantial in vivo benefit still remains uncertain. Here we review the in vitro data on the role of vitamin D in antiviral innate immunity, the data concerning the deficient levels of vitamin D in lung diseases, and the in vivo role of supplementation as protection against respiratory viral infections in healthy individuals and in patients with chronic respiratory diseases. Finally, we suggest ways of improving the effectiveness of vitamin D as an adjuvant in the prevention and treatment of acute respiratory infections.

PMID- 27714931 TI - Synthesis of honokiol analogues and evaluation of their modulating action on VEGF protein secretion and telomerase-related gene expressions. AB - A group of 36 biphenyl derivatives structurally related to honokiol were synthesized by means of Suzuki coupling reactions. Their cytotoxicities were evaluated and compared to that of honokiol. Some of the compounds were then evaluated for their ability to downregulate the secretion of the VEGF protein and the expression of the VEGF, hTERT, and c-Myc genes; the two latter involved in the activation of telomerase in tumoral cells. Some of the synthetized derivatives showed promising pharmacological features as they exhibited IC50 values in low micromolar range, good therapeutic margins, and a multiple mode of action on tumor cells based on the inhibition of VEGF and, at the same time, of the expression of genes related to the activation of telomerase. PMID- 27714932 TI - MediLex: the medical jargon-busting game. AB - BACKGROUND: During their training, medical students are expected to acquire the ability to use thousands of new terms that make up the medical lexicon. Clear communication requires knowledge of this lexicon. We developed a simple word game, MediLex, to facilitate the development of these skills. This paper describes the intervention and evaluates students' experiences. METHODS: MediLex is a card-based description game played in small groups. One hundred cards contain 500 medical terms grouped into five categories. The cardholder is asked to describe the terms on the card while group members have a limited time to deduce the term being described. Students were asked to evaluate MediLex using an electronic survey with free-text responses. Content analysis was undertaken by two independent researchers, and after discussion a consensus on themes was reached. Medical students are expected to acquire the ability to use thousands of new terms that make up the medical lexicon RESULTS: MediLex was used on six different occasions. Sixty-eight students played the game and 61 completed the survey. Fifty-six out of 61 students deemed MediLex to be a valuable learning experience. The analysis of responses revealed five themes: 'highlighted knowledge gaps'; 'revision/reactivation of knowledge'; 'explanation skills'; 'fun/engaging'; and 'fast pace'. DISCUSSION: Learning new vocabulary is a complex process, yet is a principle contributor to comprehension, fluency and achievement. Research suggests that playing games with content vocabulary allows learners to explore pronunciation and meanings simultaneously. MediLex allows learners to do this, whilst giving the opportunity to hear their peers' comprehension of meaning. Mastering the medical lexicon is a huge challenge because of the breadth and complexity of medical terminology, and focused teaching on this appears to be well received by students.

AB - There is a huge interest in developing strategies to effectively eliminate biofilms due to their negative impact in both industrial and clinical settings. In this study, structural damage was induced on two day-old B. subtilis biofilms using the interaction of 532 nm pulsed laser with gold thin films. Radiant exposure of 225 mJ/cm2 induced distinct changes on the surface structure and overall morphology of the matured biofilms after laser irradiation. Moreover, at the radiant exposure used, changes in the colour and viscosity of the biofilm were observed which may indicate a compromised extracellular matrix. Irradiated biofilms in the presence of gold film also showed strong propidium iodide signal which implies an increase in the number of dead bacterial cells after laser treatment. Thus, this laser-based technique is a promising approach in targeting and eradicating matured biofilms attached on surfaces such as medical implants. PMID- 27714934 TI - Organofluorine Isoselenocyanate Analogues of Sulforaphane: Synthesis and Anticancer Activity. AB - A series of previously unknown sulforaphane analogues with organofluorine substituents bonded to the sulfinyl sulfur atom, an isoselenocyanate moiety in place of the isothiocyanate group, the central sulfur atom in various oxidation states, and different numbers of methylene groups in the central alkyl chain were synthesized and fully characterized. All new compounds were tested for their biological properties in vitro and demonstrated much higher anticancer activity against two breast cancer cell lines than that shown by native sulforaphane; at the same time, the compounds were less toxic for normal cells. The influence of the particular structural changes in the molecules on the cytotoxicity is discussed. PMID- 27714935 TI - Is Reading Impairment Associated with Enhanced Holistic Processing in Comparative Visual Search? AB - This study explores a proposition that individuals with dyslexia develop enhanced peripheral vision to process visual-spatial information holistically. Participants included 18 individuals diagnosed with dyslexia and 18 who were not. The experiment used a comparative visual search design consisting of two blocks of 72 trials. Each trial presented two halves of the display each comprising three kinds of shapes in three colours to be compared side-by-side. Participants performed a conjunctive search to ascertain whether the two halves were identical. In the first block, participants were provided no instruction regarding the visual-spatial processing strategy they were to employ. In the second block, participants were instructed to use a holistic processing strategy to defocus their attention and perform the comparison by examining the whole screen at once. The results did not support the hypothesis associating dyslexia with talents for holistic visual processing. Using holistic processing strategy, both groups scored lower in accuracy and reacted faster, compared to the first block. Impaired readers consistently reacted more slowly and did not exhibit enhanced accuracy. Given the extant evidence of strengths for holistic visual processing in impaired readers, these findings are important because they suggest such strengths may be task dependent.

AB - Stanozolol (STAN) is one of the most frequently detected anabolic androgenic steroids in sports drug testing. STAN misuse is commonly detected by monitoring metabolites excreted conjugated with glucuronic acid after enzymatic hydrolysis or using direct detection by liquid chromatography-tandem mass spectrometry (LC MS/MS). It is well known that some of the previously described metabolites are the result of the formation of sulfate conjugates in C17, which are converted to their 17-epimers in urine. Therefore, sulfation is an important phase II metabolic pathway of STAN that has not been comprehensively studied. The aim of this work was to evaluate the sulfate fraction of STAN metabolism by LC-MS/MS to establish potential long-term metabolites valuable for doping control purposes. STAN was administered to six healthy male volunteers involving oral or intramuscular administration and urine samples were collected up to 31 days after administration. Sulfation of the phase I metabolites commercially available as standards was performed in order to obtain MS data useful to develop analytical strategies (neutral loss scan, precursor ion scan and selected reaction monitoring acquisitions modes) to detect potential sulfate metabolites. Eleven sulfate metabolites (M-I to M-XI) were detected and characterized by LC-MS/MS. This paper provides valuable data on the ionization and fragmentation of O sulfates and N-sulfates. For STAN, results showed that sulfates do not improve the retrospectivity of the detection compared to the previously described long term metabolite (epistanozolol-N-glucuronide). However, sulfate metabolites could be additional markers for the detection of STAN misuse. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27714937 TI - PlasmoSEP: Predicting surface-exposed proteins on the malaria parasite using semisupervised self-training and expert-annotated data. AB - Accurate and comprehensive identification of surface-exposed proteins (SEPs) in parasites is a key step in developing novel subunit vaccines. However, the reliability of MS-based high-throughput methods for proteome-wide mapping of SEPs continues to be limited due to high rates of false positives (i.e., proteins mistakenly identified as surface exposed) as well as false negatives (i.e., SEPs not detected due to low expression or other technical limitations). We propose a framework called PlasmoSEP for the reliable identification of SEPs using a novel semisupervised learning algorithm that combines SEPs identified by high throughput experiments and expert annotation of high-throughput data to augment labeled data for training a predictive model. Our experiments using high throughput data from the Plasmodium falciparum surface-exposed proteome provide several novel high-confidence predictions of SEPs in P. falciparum and also confirm expert annotations for several others. Furthermore, PlasmoSEP predicts that 25 of 37 experimentally identified SEPs in Plasmodium yoelii salivary gland sporozoites are likely to be SEPs. Finally, PlasmoSEP predicts several novel SEPs in P. yoelii and Plasmodium vivax malaria parasites that can be validated for further vaccine studies. Our computational framework can be easily adapted to improve the interpretation of data from high-throughput studies.

AB - We present a rare case of giant cell-rich solitary fibrous tumor (SFT) arising at the left external auditory canal in a 31-year-old woman. The tumor was well circumscribed and composed of spindle-shaped cells with abundant collagenous bands. Scattered multinucleate giant cells were observed, some of which lined pseudovascular spaces. Although a focal mild-hypercellular area was observed, mitoses were rare and necrosis was absent. Interstitial mast cells were scattered, especially in the hypercellular area. Immunohistochemically, CD34, vimentin, and Bcl-2 presented diffuse positivity. Moreover, both mononuclear spindle cells and multinucleate cells showed nuclear STAT6 positivity, while NAB2 STAT6 fusion gene could not be detected by reverse transcription polymerase chain reaction using formalin-fixed specimen. These findings suggest the pathological diagnosis of giant cell-rich SFT, previously known as giant cell angiofibroma, which is a rare variant of SFT with multinucleate giant cells and occurs predominantly in orbital region. Although giant cell-rich SFTs of extra-orbital sites have been reported, to our knowledge, this is the first case arising in the external auditory canal. Giant cell-rich SFT should be considered as a differential diagnosis of spindle cell lesion with multinucleate giant cells, and STAT6 immunohistochemistry should be performed to distinguish this rare tumor from other mesenchymal neoplasms.

PMID- 27714939 TI - Tumour-Targeted Drug Delivery with Mannose-Functionalized Nanoparticles Self Assembled from Amphiphilic beta-Cyclodextrins. AB - Multivalent mannose-functionalized nanoparticles self-assembled from amphiphilic beta-cyclodextrins (beta-CDs) facilitate the targeted delivery of anticancer drugs to specific cancer cells. Doxorubicin (DOX)-loaded nanoparticles equipped with multivalent mannose target units were efficiently taken up via receptor mediated endocytosis by MDA-MB-231 breast cancer cells that overexpress the mannose receptor. Upon entering the cell, the intracellular pH causes the release of DOX, which triggers apoptosis. Targeting by multivalent mannose significantly improved the capability of DOX-loaded nanoparticles to inhibit the growth of MDA MB-231 cancer cells with minimal side effects in vivo. This targeted and controlled drug delivery system holds promise as a nanotherapeutic for cancer treatment. PMID- 27714941 TI - Bevacizumab for non-small-cell lung cancer: A nested case control study of risk factors for hemoptysis. AB - Potentially life-threatening, serious hemoptysis is an adverse event associated with bevacizumab in non-squamous non-small-cell lung cancer (NSCLC) trials. Suggested risk factors include central tumor location and cavitation; however, the profile of hemoptysis occurrence in clinical practice is still unclear. A nested case-control study was conducted to assess the onset profile and risk factors for hemoptysis in bevacizumab-treated patients in a real-world setting in Japan. After bevacizumab was approved for NSCLC, physicians registered all NSCLC patients scheduled for bevacizumab therapy, from November 2009 to August 2011. Patients developing grade 2 hemoptysis requiring an injectable hemostatic agent or grade >=3 hemoptysis were selected as case subjects, matched with four control subjects each. Case report forms were collected after an observation period of 24 weeks. Radiologists assessed blinded thoracic images. Risk factors for hemoptysis were assessed by univariate and stepwise multivariate analysis. Of 6774 patients registered, 23 (0.3%) experienced grade >=2 drug-related hemoptysis. A total of 104 patients (21 cases, 83 controls) were analyzed by central reviewers for risk factors of hemoptysis occurrence. In the univariate analysis seven factors were associated with hemoptysis. In the step-wise multivariate analysis, prior thoracic radiotherapy (P = 0.1844), presence of tumor exposure in the central airway (P = 0.0256) and concomitant radiotherapy (P = 0.1169) were identified as risk factors for hemoptysis. While the incidence of hemoptysis was low in the real-world setting in Japan, the three risk factors identified, prior thoracic radiotherapy, presence of tumor exposure in the central airway and concomitant radiotherapy, should be considered when selecting patients for bevacizumab treatment. Although technically classed as a clinical trial, a nested case control study was a non-interventional surveillance study analyzing all NSCLC patients receiving bevacizumab in Japan, therefore it was not registered as a phase II/III clinical trial would be. PMID- 27714943 TI - Is HLA-E a possible genetic marker relevant for natural conception? AB - BACKGROUND: HLA-E products, class Ib human leukocyte antigens, act in the immunology of human reproduction as modulators of the maternal immune system during pregnancy. AIMS: To evaluate HLA-E role in the establishment of a viable pregnancy. MATERIALS & METHODS: HLA-E was genotyped by sequence-based typing (SBT) and analyzed for specific polymorphisms, comparing couples who underwent assisted reproduction treatment (ART) and fertile control couples. RESULTS: There was a significant difference in HLA-E allele and genotype distributions between ART couples and control couples. The allele HLA-E*01:03 was observed in 63.2% of ART men and in 35.1% of fertile men (P = 0.0032). CONCLUSION: These results suggest that HLA-E allelic variants may play a role in the modulation of immune responses in the context of the inability of natural conception and establishment of a viable pregnancy.

AB - Current ASCCP guidelines recommend repeat cytology 12 months after HPV-positive results in women aged 21-24 years with either atypical squamous cells of undetermined significance (ASCUS) or a low-grade squamous intraepithelial lesion (LSIL). The purpose of this study was to validate an algorithm in such women with ASCUS or LSIL. A multicenter cross-sectional study was carried out at three academic hospitals involving 40,847 Korean women who underwent cervical cancer screening with cytology and HPV testing with or without subsequent colposcopic biopsies between January 2007 and December 2013. Among a total of 3,193 women with available histopathology data, 762 women with ASCUS and 758 with LSIL were HPV-positive. Among HPV-positive women with ASCUS, 38.5% of women aged 21-24 years had >=CIN2, compared to 20.8% of women aged 30-65 years and 21.1% of the total women. Among HPV-positive women with LSIL, 25.8% aged 21-24 years had >=CIN2, compared to 21.2% of women aged 30-65 years and 21.9% of the total women. In HPV-positive women with ASCUS/LSIL aged less than 25 years, the prevalence of >=CIN2 lesions was 34.5%, which was significantly higher than that (21.0%) in women aged >=25 years. The risk of >=CIN2 lesions in HPV-positive Korean women aged 21-24 years with ASCUS or LSIL was not lower than that in older women. Colposcopic examination should be considered for management of HPV-positive young women with ASCUS or LSIL. Diagn. Cytopathol. 2016;44:959-963. (c) 2016 Wiley Periodicals, Inc.

AB - Recent discovery of the BRAF V595E mutation in a variety of canine cancers indicates that mutant BRAF may represent a novel therapeutic target. Presence of RAS mutations is associated with poor tumour response to BRAF inhibition but has not been investigated in BRAF-mutated canine cancers. The aim of this study was to evaluate the mutational status of three RAS genes (HRAS, KRAS and NRAS) in four types of canine carcinoma with and without the BRAF V595E mutation. Novel HRAS mutations were identified in 18% (3/17) of oral squamous cell carcinoma, whereas 17% (3/18) of pulmonary carcinoma carried KRAS or NRAS mutations. These RAS mutations and BRAF V595E were mutually exclusive, indicating similar functional consequence of these mutations (e.g. MAPK pathway activation). In contrast, RAS mutations were absent in 39 urothelial carcinoma and 19 prostatic carcinoma, adding another rational for BRAF-targeted therapy for these canine cancers.

AB - BACKGROUND: Conventional tonic spinal cord stimulation (SCS) is an effective treatment for patients with therapy-resistant complex regional pain syndrome (CRPS). Although the therapeutic effect of SCS can diminish over time due to tolerance, pain control can be regained by changing the pulse width and the amplitude and/or by increasing the stimulation frequency. This multicentre, double-blind, randomized and placebo-controlled crossover trial was conducted to investigate whether more effective pain reduction is achieved with different frequencies (trial registration, current controlled trials, ISRCTN 36655259). METHODS: The investigated settings are as follows: standard 40, 500, 1200 Hz, burst and placebo stimulation. All five were programmed in random order during the 10-week crossover period (2 weeks/setting). The primary outcome parameters were scores on the visual analogue scale (VAS), McGill Pain Questionnaire (MPQ) and the Global Perceived Effect (GPE); at the end of the crossover period, patients decided which SCS setting they preferred. A linear mixed models analysis was performed in 29 patients who completed the crossover trial. RESULTS: Significant pain reduction and GPE satisfaction was achieved with four SCS settings compared with placebo stimulation, and these four settings did not differ significantly from each other. Standard stimulation was preferred by 48% of the patients, while 52% preferred non-standard stimulation. Other than pain reduction, factors such as user-friendliness, comfort and recharging time may have influenced the patient's final decision for the preferred stimulation setting. CONCLUSIONS: Apparently, for various reasons, patients have a preference for different SCS setting. Therefore, future neuromodulation should aim to implement customized individual patient care by incorporating all stimulation options in one device. SIGNIFICANCE: This study demonstrates that standard frequency SCS is an effective therapy for patients with CRPS. However, it also demonstrates that patients can often gain better pain reduction with non-standard frequencies of SCS. Furthermore, it shows that the preferred stimulation setting is not solely driven by the amount of pain reduction, but is also influenced by which stimulation setting feels most comfortable and provides the best user friendliness. Therefore, we strive to maximize the therapeutic effects of SCS in as many patients as possible. This can be achieved with customized individual patient care by incorporating the various frequencies and waveforms into one single device.

AB - Low-power laser irradiation (LPLI) has been extensively employed to modulate inflammation in vitro and in vivo. Previous reports from our group indicated that LPLI might regulate glycemia in diabetic animals. Diabetes results in chronic hyperglycemia and therefore chronic inflammation by upregulation of inflammatory markers such as the high mobility group box 1 (HMGB1) protein. Thus this study aimed to analyze the LPLI effects upon blood glucose levels, plasma insulin and HMGB1 concentrations in a diabetes experimental rat model. Streptozotocin-induced diabetic rats were irradiated in the salivary glands area with a diode laser applied at 660 nm, 70 mW, 20 J/cm2 , 22.4 J, with a spot area of 0.028 cm2 and its effects were evaluated. LPLI significantly reduced diabetic rat hyperglycemia, without changing insulin or HMGB1 plasma levels, but possibly by ameliorating the insulin resistance in these animals. These findings suggest that LPLI might have a systemic effect, but more studies are necessary to better understand its mechanisms. Fasting blood glucose measured by peroxidase-glucose oxidase (PGO) method (A), showing a reduction of diabetic animals glycemia after LPLI. LPLI probably reduced the hyperglycemia in diabetes by improving the insulin resistance in these animals (B). C n = 10, CL n = 10, D n = 7 and DL n = 8.

PMID- 27714951 TI - Insecticide resistance, control failure likelihood and the First Law of Geography. AB - Insecticide resistance is a broadly recognized ecological backlash resulting from insecticide use and is widely reported among arthropod pest species with well recognized underlying mechanisms and consequences. Nonetheless, insecticide resistance is the subject of evolving conceptual views that introduces a different concept useful if recognized in its own right - the risk or likelihood of control failure. Here we suggest an experimental approach to assess the likelihood of control failure of an insecticide allowing for consistent decision making regarding management of insecticide resistance. We also challenge the current emphasis on limited spatial sampling of arthropod populations for resistance diagnosis in favor of comprehensive spatial sampling. This necessarily requires larger population sampling - aiming to use spatial analysis in area-wide surveys - to recognize focal points of insecticide resistance and/or control failure that will better direct management efforts. The continuous geographical scale of such surveys will depend on the arthropod pest species, the pattern of insecticide use and many other potential factors. Regardless, distance dependence among sampling sites should still hold, following the maxim that the closer two things are, the more they resemble each other, which is the basis of Tobler's First Law of Geography.

AB - Two steroids were identified in a supplement named D-2 following the detection of unknown compounds during the routine testing of an athlete's sample. The main glucuroconjugated metabolites were isolated from this urine by high performance liquid chromatography (HPLC) following enzymatic hydrolysis and identified by gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) analyses as being 2alpha-hydroxy-5alpha-androst-3-en-17-one (M1) and 2beta,3alpha dihydroxy-5alpha-androstan-17-one (M2). A third metabolite, 3alpha,4beta dihydroxy-5alpha-androstan-17-one (M3) was also detected, however in lower amounts. The precursor steroids, 5alpha-androst-2-en-17-one (1) and 5alpha androst-3-en-17-one (2) were present in the first D-2 products offered on the Internet. Later, the corresponding 17-hydroxyl compounds were offered as such or as esters (acetate, cypionate) in different relative ratios. Both M2 and M3 were synthesized from the trans-diaxial hydrolysis of the corresponding 2alpha,3alpha- and 3alpha,4alpha-epoxides (3). These were excreted in the hours following the controlled administration of the commercial product called D-2 R to a male volunteer and were also produced from the incubation of 1 and 2 with S9 liver fractions. Some preparations contain predominantly the alkene in C-2 and, therefore, an efficient detection method must include both primary metabolites M1 and M2. The latter was found equally in the fractions extracted following the enzymatic hydrolysis with beta-glucuronidase and the chemical solvolysis, which may ease its identification.

AB - INTRODUCTION: To increase the rate of arteriovenous fistula (AVF) use, assisted procedures for immature AVF have been strenuously performed. However, this is controversial in that an AVF matured by these assisted procedures may require more frequent intervention to maintain its patency, and have decreased long-term patency. METHODS: Eighty four AVFs that were matured with assisted maturation procedures and 266 AVFs that matured spontaneously without intervention, created between November 2009 and March 2013 from the hemodialysis (HD) vascular access (VA) cohort, were compared retrospectively and we also investigated the factors that may influence AVF long-term patency. Median follow-up was 26.8 months (interquartile range, 6.6-45.0 months). FINDINGS: Access survival did not differ between AVFs matured by assisted procedures and spontaneously mature AVFs (P = 0.29). In multivariate Cox regression analysis of AVF survival, age (HR, 1.029; 95% CI, 1.004-1.056; P = 0.024), maturation without assisted procedures 4-6 weeks after AVF creation (HR, 0.233; 95% CI, 0.107-0.506; P < 0.001), and AVF thrombosis (HR, 26.511; 95% CI, 10.986-63.978; P < 0.001) were significantly associated with AVF survival. Performance of assisted procedures to induce AVF maturation did not influence AVF survival (HR, 0.437; 95% CI, 0.191-1.002; P = 0.05). DISCUSSION: Our results support that idea that assisted maturation procedures can ensure the success of immature AVF without compromising long-term patency. These procedures can be considered more positively for increasing AVF use for VA placement in HD patients. PMID- 27714954 TI - Nursing with care: a meditation in three voices (in memoriam John S. Drummond). AB - This paper is a written version of a talk given at the 19th International Philosophy of Nursing conference to honour the contributions of Dr. John S. Drummond, nurse and philosopher, to an ongoing and collective project we could call 'thinking nursing'. Over the course of his career, John Drummond published a series of essays, building on his reading of the works of continental philosophers such as Nietzsche, Lyotard or Deleuze, that draw us to nursing as a matter of concern, and that through their incisive analyses, help us to pay attention to the changes that are going on with nursing now. Though this essay began as a way to mark the death of John Drummond, and to pay tribute to his work, we also find that our return to his texts is like other experiences of return - the pleasure of experiencing something anew, as if for the first time.

Excessive hypotonic fluid ingestion is the primary etiological factor but does not explain all variability. Possible effects of chronic sodium intake are unknown. The aim of this study was to determine whether dietary sodium affects plasma sodium concentration [Na+ ] during exercise in the heat, when water intake nearly matches mass loss. Endurance-trained men (n = 9) participated in this crossover experiment. Each followed a low-sodium (lowNa) or high-sodium (highNa) diet for 9 days with 24-h fluid intakes and urine outputs measured before experimental trials (day 10). The trials were >=2 week apart. Trials comprised 3 h (or if not possible to complete, to exhaustion) cycling (55% VO2max ; 34 degrees C, 65% RH) with water intake approximating mass loss. Plasma [Na+ ], hematocrit, sweat and urine [Na+ ], heart rate, core temperature, and subjective perceptions were monitored. Urine [Na+ ] was lower on lowNa 24 h prior to (31 +/- 24, 76 +/- 30 mmol/L, P = 0.027) and during trials (10 +/- 10, 52 +/- 32 mmol/L, P = 0.004). Body mass was lower on lowNa (79.6 +/- 8.5, 80.5 +/- 8.9, P = 0.03). Plasma [Na+ ] was lower on lowNa before (137 +/- 2, 140 +/- 3, P = 0.007) and throughout exercise (P = 0.001). Sweat [Na+ ] was unaffected by diet (54.5 +/- 40, 54.5 +/- 23 mmol/L, P = 0.99). Heart rate and core temperature were higher on lowNa (P <= 0.001). Despite decreased urinary sodium losses, plasma sodium was lower on lowNa, with decreased mass indicating (extracellular) water may have been less, explaining greater heart rate and core temperature. General population health recommendations to lower salt intake may not be appropriate for endurance athletes, particularly those training in the heat. PMID- 27714957 TI - Discovery of selective protein arginine methyltransferase 5 inhibitors and biological evaluations. AB - Protein arginine methyltransferase 5 (PRMT5) is an important protein arginine methyltransferase that catalyzes the symmetric dimethylation of arginine resides on histones or non-histone substrate proteins. It has been thought as a promising target for many diseases, particularly cancer. Despite the potential applications of PRMT5 inhibitors in cancer treatment, very few of PRMT5i have been publicly reported. In this investigation, virtual screening and structure-activity relationship studies were carried out to discover novel PRMT5i, which finally led to the identification of a number of new PRMT5i. The most active compound, P5i-6, exhibited a considerable inhibitory potency against PRMT5 with an IC50 value of 0.57 MUm, and a high selectivity for PRMT5 against other tested PRMTs. It displayed a very good antiviability activity against two colorectal cancer cell lines, HT-29 and DLD-1, and one hepatic cancer cell line, HepG2, in a sensitivity assay against 36 different cancer cell lines. Western blot assays indicated that P5i-6 selectively inhibited the symmetric dimethylations of H4R3 and H3R8 in DLD 1 cells. Overall, P5i-6 could be used as a chemical probe to investigate new functions of PRMT5 in biology and also served as a good lead compound for the development of new PRMT5-targeting therapeutic agents. PMID- 27714958 TI - Prenatal anemia control and anemia in children aged 6-23 months in sub-Saharan Africa. AB - It is unclear whether routine prenatal anemia control interventions can reduce anemia risk in young children. This study examines the associations between prenatal iron supplementation and/or deworming and anemia in children aged 6-23 months in sub-Saharan Africa (SSA). We analyzed data from Demographic and Health Surveys conducted between 2003 and 2014 in 25 SSA countries. The surveys collected data on prenatal iron supplementation and deworming and determined children's hemoglobin levels through blood testing. We assessed the associations between prenatal iron supplementation and/or deworming and anemia using multinomial logistic regression. The study included 31,815 mother-child pairs: 25.0%, 41.4%, and 4.8% of children had mild, moderate, and severe anemia, respectively. Compared with children whose mothers did not take iron and deworming drugs prenatally, the risk of moderate/severe anemia was reduced among children whose mothers took only iron supplements for >=6 months (odds ratio [OR]: 0.58; 95% confidence interval [CI]: 0.45-0.76); only deworming drugs (OR: 0.73; 95% CI: 0.56-0.93); deworming drugs plus iron for <6 months (OR: 0.79; 95% CI: 0.67-0.93); and deworming drugs plus iron for >=6 months (OR: 0.77; 95% CI: 0.59-0.99). Prenatal use of only iron for <6 months was not associated with moderate/severe anemia. Prenatal iron and/or deworming drugs had no effect on mild anemia. Prenatal anemia control interventions are associated with reduced risk of moderate/severe anemia but not with mild anemia in young children in SSA. Iron supplements should be taken for >=6 months or with deworming drugs prenatally to reduce moderate/severe anemia risk in children. PMID- 27714959 TI - Doctors with dyslexia: strategies and support. AB - BACKGROUND: Looking beyond dyslexia as an individual doctor's issue requires adjusting a working environment to better serve the needs of doctors with dyslexia. With an increasing number of doctors disclosing dyslexia at medical school, how can educators best provide this support? Our research looks at the impact of dyslexia on clinical practice and the coping strategies used by doctors to minimise the effect. METHODS: Qualitative data were collected from 14 doctors with dyslexia using semi-structured interviews and by survey. 'In situ' demonstration interviews were conducted in order to understand how dyslexia is managed in the workplace from first-hand experience. Employers and educators who have responsibility for meeting the needs of this group were also consulted. RESULTS: Even in cases of doctors who had a diagnosis, they often did not disclose their dyslexia to their employer. Study participants reported having developed individual ways of coping and devised useful 'workarounds'. Support from employers comes in the form of 'reasonable adjustments', although from our data we cannot be sure that such adjustments contribute to an 'enabling' work environment. Supportive characteristics included the opportunity to shadow others and the time and space to complete paperwork on a busy ward. How can educators best provide support [for doctors with dyslexia]? DISCUSSION: Doctors with dyslexia need to be helped to feel comfortable enough to disclose. Educators need to challenge any negative assumptions that exist as well as promote understanding about the elements that contribute to a positive working environment. As a result of the research there is now practice available for educators to identify evidence-based strategies and resources. PMID- 27714956 TI - Deficiency of plasminogen receptor, Plg-RKT , causes defects in plasminogen binding and inflammatory macrophage recruitment in vivo. AB - : Essentials Plg-RKT is a novel integral membrane plasminogen receptor. The functions of Plg-RKT in vivo are not known. Plg-RKT is a key player in macrophage recruitment in the inflammatory response in vivo. Plg-RKT deficiency is not compatible with survival of the species. SUMMARY: Background Plg-RKT is a novel integral membrane plasminogen receptor that binds plasminogen via a C-terminal lysine exposed on the cell surface and promotes plasminogen activation on the cell surface by both tissue plasminogen activator and urokinase plasminogen activator. Objectives To evaluate the role of Plg-RKT in vivo we generated Plg RKT-/- mice using a homologous recombination technique. Methods We characterized the effect of Plg-RKT deletion on reproduction, viability, health and spontaneous thrombosis and inflammation. Results Plg-RKT-/- mice were viable and fertile. Survival of Plg-RKT-/- mice and Plg-RKT+/+ littermates was not significantly different. However, quite strikingly, all pups of Plg-RKT-/- females died within 2 days of birth, consistent with a lactation defect in Plg-RKT-/- mothers. Additionally, there was a significant effect of Plg-RKT deficiency on the growth rates of female, but not male, mice. In experimental peritonitis studies, Plg-RKT /- mice exhibited a marked defect in macrophage recruitment. As a contributing mechanism, the capacity of Plg-RKT-/- macrophages for plasminogen binding was markedly decreased. Conclusions These studies demonstrate that Plg-RKT is required for plasminogen binding and macrophage migration in vivo. In addition, Plg-RKT deficiency is not compatible with survival of the species, due to the death of all offspring of Plg-RKT-/- females. This new mouse model will be important for future studies aimed at delineating the role of cell surface plasminogen activation in challenge and disease models in vivo. PMID- 27714960 TI - Risk factors for treatment-related adverse events in cancer-bearing dogs receiving piroxicam. AB - Piroxicam has antitumour effects in dogs with cancer, although side effects may limit its use. The purpose of this study was to retrospectively identify factors predisposing cancer-bearing dogs to adverse events (AEs) following piroxicam therapy. Medical records of dogs presented to the Purdue Veterinary Teaching Hospital between 2005 and 2015 were reviewed, and 137 dogs met the criteria for study inclusion. Toxic effects of piroxicam in these dogs were graded according to an established system. Multivariate logistic regression was used to estimate the extent to which certain factors affected the risk for AEs. Age [odds ratio (OR) 1.250, P = 0.009; 95% confidence interval (CI) 1.057-1.479] and concurrent use of gastroprotectant medications (OR 2.612, P = 0.025; 95% CI 1.127-6.056) significantly increased the risk for gastrointestinal AEs. The results of this study may help inform the risk versus benefit calculation for clinicians considering the use of piroxicam to treat dogs with cancer.

AB - Fanconi anemia is a heterogeneous genetic disorder that is characterized by progressive bone marrow failure, congenital anomalies, and markedly increased risk for malignancies. Mutations in the FANCF (FA-F) gene represent approximately 2% of affected patients. Currently, information on the phenotypic findings of patients with Fanconi anemia from biallelic mutations in FANCF is limited. Here, we report three patients who illustrate the clinical variability within the FA-F group. This analysis suggests a more severe phenotype for those with the common c.484_485delCT mutation.

AB - AIM: The aim of the study was to assess the utility of blood cultures in children admitted to hospital with community-acquired pneumonia. The primary outcome was the number of positive blood culture results, and secondary outcomes included the effect of positive blood culture results on management, and the identification of other clinical/biochemical variables that could predict blood culture results or the course of illness. METHODS: A retrospective data analysis was carried out on all children admitted to Gosford Hospital during the 2-year period from July 2013 to June 2015. Included were patients under 16 years old who had a diagnosis related group code of pneumonia. A review of blood culture results, chest X-ray, serology, C-reactive protein and white cell count and clinical outcomes were analysed. RESULTS: There were 215 paediatric admissions with a diagnosis of pneumonia during the 2-year study period. A blood culture was collected in 82.3% (177/215). Although seven had a positive blood culture, only two of these were finally reported as true positives and both were Streptococcus pneumoniae. Both patients were treated with a cephalosporin and demonstrated clinical improvement. No changes were made to their treatment based on the blood culture results. CONCLUSION: Blood cultures have a low yield and do not appear to be helpful when collected in all patients admitted to hospital with community-acquired pneumonia.

AB - Improving our comprehension of diverse CO2 activation pathways is of vital importance for the widespread future utilization of this abundant greenhouse gas. CO2 activation by uranium(III) complexes is now relatively well understood, with oxo/carbonate formation predominating as CO2 is readily reduced to CO, but isolated thorium(III) CO2 activation is unprecedented. We show that the thorium(III) complex, [Th(Cp'')3 ] (1, Cp''={C5 H3 (SiMe3 )2 -1,3}), reacts with CO2 to give the mixed oxalate-carboxylate thorium(IV) complex [{Th(Cp'')2 [kappa2 -O2 C{C5 H3 -3,3'-(SiMe3 )2 }]}2 (MU-kappa2 :kappa2 -C2 O4 )] (3). The concomitant formation of oxalate and carboxylate is unique for CO2 activation, as in previous examples either reduction or insertion is favored to yield a single product. Therefore, thorium(III) CO2 activation can differ from better understood uranium(III) chemistry. PMID- 27714967 TI - Remission spectrometry for blood vessel detection during stereotactic biopsy of brain tumors. AB - Stereotactic biopsy is used to enable diagnostic confirmation of brain tumors and treatment planning. Despite being a well-established technique, it is related to significant morbidity and mortality rates mostly caused by hemorrhages due to blood vessel ruptures. This paper presents a method of vessel detection during stereotactic biopsy that can be easily implemented by integrating two side-view fibers into a conventional side-cutting biopsy needle. Tissue within the needle window is illuminated through the first fiber; the second fiber detects the remitted light. By taking the ratio of the intensities at two wavelengths with strongly differing hemoglobin absorption, blood vessels can be recognized immediately before biopsy sampling. Via ray tracing simulations and phantom experiments, the dependency of the remission ratio R = I578 /I650 on various parameters (blood oxygenation, fiber-to-vessel and inter-fiber distance, vessel diameter and orientation) was investigated for a bare-fiber probe. Up to 800-1200 um away from the probe, a vessel can be recognized by a considerable reduction of the remission ratio from the background level. The technique was also successfully tested with a real biopsy needle probe on both optical phantoms and ex-vivo porcine brain tissue, thus showing potential to improve the safety of stereotactic biopsy. Dual-wavelength remission measurement for the detection of blood vessels during stereotactic biopsy. PMID- 27714968 TI - Antiamyloidogenic Activity of Abeta42-Binding Peptoid in Modulating Amyloid Oligomerization. AB - The oligomerization and aggregation of amyloid beta (Abeta) play central role in the pathogenesis of Alzheimer's disease (AD). Molecular binding agents for modulating the formation of Abeta oligomers and fibrils have promising application potential in AD therapies. By screening a peptoid library using surface plasmon resonance imaging, amyloid inhibitory peptoid 1 (AIP1) that has high affinity to Abeta42 is identified. AIP1 is demonstrated to inhibit Abeta42 oligomerization and fibrillation and to rescue Abeta42-induced cytotoxicity through decreasing the content of Abeta42 oligomers that is related to cell membrane permeability. Molecular docking suggests that the binding sites of AIP1 may be at the N-terminus of Abeta42. The blood-brain barrier (BBB) permeability of AIP1 using an in vitro BBB model is also revealed. This work provides a strategy for the design and development of peptoid-based antiamyloidogenic agents. The obtained amyloid inhibitory peptoid shows prospects in the therapeutic application in AD. PMID- 27714969 TI - Raman spectroscopic identification of Mycobacterium tuberculosis. AB - In this study, Raman microspectroscopy has been utilized to identify mycobacteria to the species level. Because of the slow growth of mycobacteria, the per se cultivation-independent Raman microspectroscopy emerges as a perfect tool for a rapid on-the-spot mycobacterial diagnostic test. Special focus was laid upon the identification of Mycobacterium tuberculosis complex (MTC) strains, as the main causative agent of pulmonary tuberculosis worldwide, and the differentiation between pathogenic and commensal nontuberculous mycobacteria (NTM). Overall the proposed model considers 26 different mycobacteria species as well as antibiotic susceptible and resistant strains. More than 8800 Raman spectra of single bacterial cells constituted a spectral library, which was the foundation for a two-level classification system including three support vector machines. Our model allowed the discrimination of MTC samples in an independent validation dataset with an accuracy of 94% and could serve as a basis to further improve Raman microscopy as a first-line diagnostic point-of-care tool for the confirmation of tuberculosis disease. PMID- 27714971 TI - Changes in endogenous UV fluorescence and biomechanical stiffness of bovine articular cartilage after collagenase digestion are strongly correlated. AB - A significant source of morbidity in the elderly population of the United States is osteoarthritis (OA), a disease caused by the breakdown and loss of articular cartilage. The exact causes of OA remain unknown, though biomechanical forces and biochemical alterations are important factors. There exists an unmet need for an imaging tool to identify early lesions of OA via metabolic, chemical or structural changes. Our work aims to characterize changes in the intensity of UV fluorescent bands associated with known structural proteins of cartilage. We employed an OA model in which bovine osteochondral plugs were digested in collagenase of varying concentrations. UV fluorescence before and after proteolytic digestion was measured using a spectrofluorimeter. The elastic modulus (EM) of each sample was measured using an indentation apparatus. Hydroxypyridinoline crosslink (330/390 nm) fluorescence intensity after digestion correlated with cartilage EM (R = 0.922, p = 0.026), as did tryptophan (290/350 nm) fluorescence intensity after digestion and EM (R = 0.949, p = 0.014) and tyrosine (290/310 nm) fluorescence intensity after digestion and EM (R = 0.946, p = 0.015). Loss of endogenous UV fluorescence correlated with cartilage degradation in an in-vitro model of OA, and may serve as a sensitive optical biomarker for the state of cartilage. PMID- 27714972 TI - Environmental gradients shape the genetic structure of two medicinal Salvia species in Jordan. AB - Environmental gradients, and particularly climatic variables, exert a strong influence on plant distribution and, potentially, population genetic diversity and differentiation. Differences in water availability can cause among-population variation in ecological processes and can thus interrupt populations' connectivity and isolate them environmentally. The present study examines the effect of environmental heterogeneity on plant populations due to environmental isolation unrelated to geographic distance. Using AFLP markers, we analyzed genetic diversity and differentiation among 12 Salvia spinosa populations and 13 Salvia syriaca populations from three phytogeographical regions (Mediterranean, Irano-Turanian and Saharo-Arabian) representing the extent of the species' geographic range in Jordan. Differences in geographic location and climate were considered in the analyses. For both species, flowering phenology varied among populations and regions. Irano-Turanian and Saharo-Arabian populations had higher genetic diversity than Mediterranean populations, and genetic diversity increased significantly with increasing temperature. Genetic diversity in Salvia syriaca was affected by population size, while genetic diversity responded to drought in S. spinosa. For both species, high levels of genetic differentiation were found as well as two well-supported phytogeographical groups of populations, with Mediterranean populations clustering in one group and the Irano-Turanian and Saharo-Arabian populations in another. Genetic distance was significantly correlated to environmental distance, but not to geographic distance. Our data indicate that populations from moist vs. arid environments are environmentally isolated, where environmental gradients affect their flowering phenology, limit gene flow and shape their genetic structure. We conclude that environmental heterogeneity may act as driver for the observed variation in genetic diversity.

AB - Chytrids are true fungi that reproduce with posteriorly uniflagellate zoospores. In the last decade, environmental DNA surveys revealed a large number of uncultured chytrids as well as undescribed order-level novel clades in Chytridiomycota. Although many species have been morphologically described, only some DNA sequence data of parasitic chytrids are available from the database. We herein discuss five cultures of parasitic chytrids on diatoms Aulacoseira spp. and Asterionella formosa. In order to identify the chytrids examined, thallus morphologies were observed using light microscopy. We also conducted a phylogenetic analysis using 18S, 5.8S, and 28S rDNA sequences to obtain their phylogenetic positions. Based on their morphological characteristics, two cultures parasitic on As. formosa were identified as Rhizophydium planktonicum and Zygorhizidium planktonicum. The other three cultures infecting Aulacoseira spp. (two on Aulacoseira ambigua and the other on Aulacoseira granulata) were regarded as Zygorhizidium aff. melosirae. The results of the molecular phylogenetic analysis revealed that R. planktonicum belonged to the known order Chytridiales, while the two species of Zygorhizidium were placed in a novel clade that was previously reported as an undescribed clade composed of only the environmental sequences of uncultured chytrids.

AB - One of the major challenges in evolutionary biology is to unravel the genetic basis of adaptation. This issue has been gaining momentum in recent years with the accelerated development of novel genetic and genomic techniques and resources. In this issue of Molecular Ecology, Cogni et al. (2016) address the genetic basis of resistance to two viruses in Drosophila melanogaster using a panel of recombinant inbred lines with unprecedented resolution allowing detection of rare alleles and/or alleles of small effect. The study confirms the role of previously identified genes of major effect and adds novel regions with minor effect to the genetic basis of Drosophila resistance to the Drosophila C virus or the sigma virus. Additional analyses reveal the absence of cross resistance and of epistasis between the various genomic regions. This detailed information on the genetic architecture of host resistance constitutes an important step towards the understanding of both the physiology of antiviral immunity and the evolution of host-parasite interactions.

AB - Differences in breastfeeding, other milk feeding and complementary feeding patterns were evaluated in infants at increased genetic risk with and without maternal type 1 diabetes (T1D). The Trial to Reduce IDDM in the Genetically at Risk is an international nutritional primary prevention double-blinded randomized trial to test whether weaning to extensively hydrolyzed vs. intact cow's milk protein formula will decrease the development of T1D-associated autoantibodies and T1D. Infant diet was prospectively assessed at two visits and seven telephone interviews between birth and 8 months. Countries were grouped into seven regions: Australia, Canada, Northern Europe, Southern Europe, Central Europe I, Central Europe II and the United States. Newborn infants with a first-degree relative with T1D and increased human leukocyte antigen-conferred susceptibility to T1D were recruited. A lower proportion of infants born to mothers with than without T1D were breastfed until 6 months of age in all regions (range, 51% to 60% vs. 70% to 80%). Complementary feeding patterns differed more by region than by maternal T1D. In Northern Europe, a higher proportion of infants consumed vegetables and fruits daily compared with other regions. Consumption of meat was more frequent in all European regions, whereas cereal consumption was most frequent in Southern Europe, Canada and the United States. Maternal T1D status was associated with breastfeeding and other milk feeding patterns similarly across regions but was unrelated to the introduction of complementary foods. Infant feeding patterns differed significantly among regions and were largely inconsistent with current recommended guidelines. PMID- 27714977 TI - The long chain alpha-tocopherol metabolite alpha-13'-COOH and gamma-tocotrienol induce P-glycoprotein expression and activity by activation of the pregnane X receptor in the intestinal cell line LS 180. AB - SCOPE: Members of the vitamin E family or their metabolites may induce the xenobiotic transporter P-glycoprotein (P-gp), which can limit the bioavailability of drugs and phytochemicals. This study aimed to investigate if alpha- and gamma tocopherol, alpha- and gamma-tocotrienol, the long chain metabolite alpha tocopherol-13'-COOH, the short chain metabolites alpha- and gamma carboxyethylhydroxychromanol and plastochromanol-8 activate the pregnane X receptor (PXR) and thereby modulate P-gp expression and/or activity. METHODS AND RESULTS: P-gp protein expression and activity were studied in LS 180 cells incubated with the respective test compound for 48 h. Furthermore, we determined if the compounds activate PXR in LS 180 cells, as PXR regulates P-gp expression. Neither P-gp protein expression and activity, nor PXR activity were influenced by alpha-tocopherol, gamma-tocopherol and plastochromanol-8. alpha-Tocotrienol activated PXR in the reporter gene assay but did not induce protein expression or activity of P-gp. gamma-Tocotrienol and alpha-13'-COOH activated PXR and induced protein expression and transporter activity of P-gp. CONCLUSION: Because the induction of P-gp in the intestine may limit the systemic bioavailability of its substrates, the concurrent intake of drugs and gamma-tocotrienol and, if ever applicable, alpha-13'-COOH should be avoided.

AB - In an era when most individuals with treated HIV infection can expect to live into old age, clinicians should proactively review their patients' current and future treatment needs and challenges. Clinical guidelines acknowledge that, in the setting of virological suppression, treatment switch may yield benefits in terms of tolerability, regimen simplification, adherence, convenience and long term health considerations, particularly in the context of ageing. In this paper, we review evidence from six key clinical studies on switching virologically suppressed patients to regimens based on integrase strand transfer inhibitors (INSTIs), the antiretroviral class increasingly preferred as initial therapy in clinical guidelines. We review these studies and focus on the virological efficacy, safety, and tolerability of switching to INSTI-based regimens in suppressed HIV-positive individuals. We review the early switch studies SWITCHMRK and SPIRAL [assessing a switch from a ritonavir-boosted protease inhibitor (PI/r) to raltegravir (RAL)-containing regimens], together with data from STRATEGY-PI [assessing a switch to elvitegravir (EVG)-containing regimens; EVG/cobicistat (COBI)/emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) vs. remaining on a PI/r-containing regimen], STRATEGY-NNRTI [assessing a switch to EVG/COBI/FTC/TDF vs. continuation of a nonnucleoside reverse transcriptase inhibitor (NNRTI) and two nucleoside reverse transcriptase inhibitors (NRTIs)], STRIIVING [assessing a switch to a dolutegravir (DTG)-containing regimen (abacavir (ABC)/lamivudine (3TC)/DTG) vs. staying on the background regimen], and GS study 109 [assessing a switch to EVG/COBI/FTC/tenofovir alafenamide fumarate (TAF) vs. continuation of FTC/TDF-based regimens]. Switching to INSTI-containing regimens has been shown to support good virological efficacy, with evidence from two studies demonstrating superior virological efficacy for a switch to EVG-containing regimens. In addition, switching to INSTI regimens was associated with improved tolerability and greater reported patient satisfaction and outcomes in some studies. INSTI based regimens offer an important contemporary switch option that may be tailored to meet and optimize the needs of many patients.

AB - Brucine chloromethochloride and strychnine chloromethochloride, the two chloromethochloride derivatives formed during the extraction of Semen Strychni in which dichloromethane was used as the extracting solvent, were isolated and purified by high-speed countercurrent chromatography for the first time. The two phase solvent system composed of chloroform/methanol/0.3 mol/L hydrochloric acid (4:3:2, v/v/v) was selected for separation. From 300 mg of the crude extracts, 56.2 mg of brucine chloromethochloride and 60.2 mg of strychnine chloromethochloride were obtained with the purity of 99.78 and 96.99%, respectively, and the structures were confirmed by mass spectrometry, 1 H, 13 C, and two-dimensional NMR spectroscopy. The results indicated that the present method is a powerful technology for large-scale isolation of alkaloids from Semen Strychni. PMID- 27714981 TI - Exceptionally Selective and Tunable Sensing of Guanine Derivatives and Analogues by Structural Complementation in a G-Quadruplex. AB - A guanine-vacancy-bearing G-quadruplex (GVBQ) interacts with guanine and derivatives by a structural complementation to form a more stable and intact G quadruplex. Sensors using GVBQs are devised to detect guanine and other nucleobases, and their derivatives derived from structurally similar compounds. A strict requirement of Hoogsteen hydrogen bonds between the GVBQ and analyte in the structural complementation confers exceptional selectivity on the analyte. As such, subtle modifications on analytes affecting even a single hydrogen bond can preclude the recognition. In principle, the strategy may also be expanded to detect many planar cyclic compounds. Because nucleobases and derivatives/metabolites are involved in many physiological and pathological processes, this type of sensor may find applications in risk assessment of pathogenesis and therapeutics related to nucleic acid metabolism. PMID- 27714979 TI - Nonoxidative ethanol metabolism in humans-from biomarkers to bioactive lipids. AB - Ethanol is a widely used psychoactive drug whose chronic abuse is associated with organ dysfunction and disease. Although the prevalent metabolic fate of ethanol in the human body is oxidation a smaller fraction undergoes nonoxidative metabolism yielding ethyl glucuronide, ethyl sulfate, phosphatidylethanol and fatty acid ethyl esters. Nonoxidative ethanol metabolites persist in tissues and body fluids for much longer than ethanol itself and represent biomarkers for the assessment of ethanol intake in clinical and forensic settings. Of note, the nonoxidative reaction of ethanol with phospholipids and fatty acids yields bioactive compounds that affect cellular signaling pathways and organelle function and may contribute to ethanol toxicity. Thus, despite low quantitative contributions of nonoxidative pathways to overall ethanol metabolism the resultant ethanol metabolites have important biological implications. In this review we summarize the current knowledge about the enzymatic formation of nonoxidative ethanol metabolites in humans and discuss the implications of nonoxidative ethanol metabolites as biomarkers of ethanol intake and mediators of ethanol toxicity.

AB - As a new member of carbon allotropes, graphdiyne is a promising material with excellent electronic performance and high elasticity, indicating the possibility of graphdiyne to serve as the building blocks in flexible electronics. However, precise positioning/patterning of graphdiyne is still a challenge for the realization of large-area and flexible organic electronic devices and circuits. Here, the direct in situ synthesis of patterning graphdiyne stripe arrays dominated by the superlyophilic grooved templates is reported, whereas the superlyophilicity of grooved templates plays a key role in allowing continuous mass transport of raw reactants into the microscale spacing. After the completion of cross-coupling reaction procedure, precisely patterned graphdiyne stripes can be generated accordingly. The size of graphdiyne stripe arrays is depending on the silicon substrate size (1 cm * 1.5 cm), and the layer thickness can be manipulated from just several nanometers to hundreds of nanometers by varying the primary concentration of hexaethynylbenzene monomers. As a proof-of-principle demonstration, a stretchable sensor based on the graphdiyne stripe arrays is performed to monitor the human finger motion. It is expected that this wettability-facilitated strategy will provide new insights into the controlled synthesis of graphdiyne toward promising flexible electronics and other optoelectronic applications. PMID- 27714983 TI - Porcine models for the study of small-for-size syndrome and portal inflow modulation: literature review and proposal for a standardized nomenclature. AB - Porcine models of extended hepatectomy and liver transplantation (LT) of reduced graft have been widely used for studying the small-for-size (SFS) syndrome and the various modalities of portal inflow modulation (PIM). However, considerable heterogeneity exists among the studies and their results. The aim of this review was to assess the main advantages and drawbacks of the different porcine models of SFS LT and SFS hepatectomy, and propose a standardized anatomical nomenclature for the various models. The MEDLINE database was searched for articles reporting porcine models of reduced graft LT or hepatectomy of more than 65%. Nineteen articles on SFS LT matched our inclusion criteria, including 10 articles reporting a model of PIM. Twenty-seven articles reporting a model of posthepatectomy SFS were identified, of which 16 reported a model of PIM. Subtotal hepatectomy (i.e. resection of all segments except segment 1) without inflow occlusion, left trisectionectomy with inflow occlusion, and LT of a right lateral section including the caudate lobe in a larger recipient appeared to be the most suitable porcine models for studying the SFS syndrome. All three models were appropriate for assessing the surgical and pharmaceutical PIM modalities, except for those involving the splenic flow. PMID- 27714984 TI - Quantification of three beta-lactam antibiotics in breast milk and human plasma by hydrophilic interaction liquid chromatography/positive-ion electrospray ionization mass spectrometry. AB - The use of cephalosporins during breast feeding raises several issues, including the risk of drug exposure through breast milk for the infant. In this paper, a hydrophilic interaction liquid chromatography/positive ion electrospray mass spectrometric assay (HILIC/ESI-MS) was developed for the quantitation of cefuroxime, cefoxitin, and cefazolin in breast milk and human plasma. The assay was based on the use of small sample size, 25 MUL of biological samples, following acetonitrile precipitation of proteins and filtration that enabled injection into the HILIC/ESI-MS system. All analytes and the internal standard, alfuzosin, were separated by using a ZIC(r)-HILIC analytical column (150.0 * 2.1 mm i.d., particle size 3.5 um, 200 A) with isocratic elution. The mobile phase was composed of a 6% 12.5 mM ammonium acetate water solution in acetonitrile and pumped at a flow rate of 0.25 mL min-1 . The assay was linear over a concentration range of 0.2 to 5 ug mL-1 and 0.4 to 20 ug mL-1 for all the analytes in breast milk and in human plasma, respectively. Intermediate precision was found to be less than 4.2% over the tested concentration ranges. A run time of less than 12 min for each sample made it possible to analyze a large number of biological samples per day. The method is the first reported application of HILIC in the analysis of antibiotics in breast milk and human plasma and it can be used to support a wide range of clinical studies.

PMID- 27714985 TI - Development of an evidence-based fall risk assessment tool and evaluation of interrater reliability and nurses' perceptions of the tool's clarity and usability. AB - AIM: To develop and test interrater reliability of an evidence-based fall risk assessment tool for nurses and to investigate how nurses perceived the clarity and usability of the tool. METHODS: In phase 1, an evidence-based fall risk assessment tool was developed based on a literature review and expert discussion. The finalized tool assessed 11 risk factors and comprised 23 items. In phase 2, reliability testing was done. Two nurses out of a possible 125 participating nurses independently assessed each participating patient on admission with the assessment tool. The nurses then provided feedback on the clarity and usability of the tool. The interrater reliability was estimated by the percentage agreement, Cohen's kappa, and prevalence- and bias-adjusted kappa. RESULTS: Of the 164 patients who were recruited, 114 patients participated. After adjustment for prevalence and bias, only "frequent urination" and "night-time toileting" showed a less-than-substantial interrater agreement. Assessment of the items "cognitive impairment" and "night-time toileting" were most frequently reported to be problematic. CONCLUSION: The evidence-based fall risk assessment tool requires further modification and re-examination of interrater reliability is warranted. In particular, the cognitive impairment items need to be reconsidered in order to enable nurses to better assess patient cognition on the admission day. PMID- 27714986 TI - Effects of Water Loss on New Mexico Spadefoot Toad (Spea multiplicata) Development, Spleen Cellularity, and Corticosterone Levels. AB - Amphibian metamorphosis is complex and larval morphology and physiology are completely restructured during this time. Amphibians that live in unpredictable environments are often exposed to stressors that can directly and indirectly alter physiological systems during development, with subsequent consequences (carryover effects) later in life. In this study, we investigated the effects of water level reduction on development rate, spleen size and cellularity, and examined the role of corticosterone levels in premetamorphic, metamorphic, and postmetamorphic New Mexico spadefoot toads (Spea multiplicata). Based on previous studies, we hypothesized that declining water level would increase tadpole developmental rate, but with the trade-off of increasing corticosterone to a level that would subsequently affect spleen size and cellularity, thus prolonging potential immunological suppression. Declining water levels increased developmental rate by 3 days; however, there were no significant body size effects. Corticosterone (CORT) was negatively correlated with total length, snout vent length, body weight, and spleen weight at metamorphosis, suggesting that size at metamorphosis and the immune system may be affected by excessive CORT levels. When compared to other studies, our results support the view that multiple factors may be acting as stressors in the field affecting amphibian responses, and simple pathways as tested in this study may not adequately represent field conditions. PMID- 27714987 TI - In vitro characterization of biofilms formed by Kingella kingae. AB - The Gram-negative bacterium Kingella kingae is part of the normal oropharyngeal mucosal flora of children <4 years old. K. kingae can enter the submucosa and cause infections of the skeletal system in children, including septic arthritis and osteomyelitis. The organism is also associated with infective endocarditis in children and adults. Although biofilm formation has been coupled with pharyngeal colonization, osteoarticular infections, and infective endocarditis, no studies have investigated biofilm formation in K. kingae. In this study we measured biofilm formation by 79 K. kingae clinical isolates using a 96-well microtiter plate crystal violet binding assay. We found that 37 of 79 strains (47%) formed biofilms. All strains that formed biofilms produced corroding colonies on agar. Biofilm formation was inhibited by proteinase K and DNase I. DNase I also caused the detachment of pre-formed K. kingae biofilm colonies. A mutant strain carrying a deletion of the pilus gene cluster pilA1pilA2fimB did not produce corroding colonies on agar, autoaggregate in broth, or form biofilms. Biofilm forming strains have higher levels of pilA1 expression. The extracellular components of biofilms contained 490 MUg cm-2 of protein, 0.68 MUg cm-2 of DNA, and 0.4 MUg cm 2 of total carbohydrates. We concluded that biofilm formation is common among K. kingae clinical isolates, and that biofilm formation is dependent on the production of proteinaceous pili and extracellular DNA. Biofilm development may have relevance to the colonization, transmission, and pathogenesis of this bacterium. Extracellular DNA production by K. kingae may facilitate horizontal gene transfer within the oral microbial community. PMID- 27714989 TI - Optical redox ratio and endogenous porphyrins in the detection of urinary bladder cancer: A patient biopsy analysis. AB - Bladder cancer is among the most common cancers in the UK and conventional detection techniques suffer from low sensitivity, low specificity, or both. Recent attempts to address the disparity have led to progress in the field of autofluorescence as a means to diagnose the disease with high efficiency, however there is still a lot not known about autofluorescence profiles in the disease. The multi-functional diagnostic system "LAKK-M" was used to assess autofluorescence profiles of healthy and cancerous bladder tissue to identify novel biomarkers of the disease. Statistically significant differences were observed in the optical redox ratio (a measure of tissue metabolic activity), the amplitude of endogenous porphyrins and the NADH/porphyrin ratio between tissue types. These findings could advance understanding of bladder cancer and aid in the development of new techniques for detection and surveillance. PMID- 27714990 TI - Multifunctional Textured Surfaces with Enhanced Friction and Hydrophobic Behaviors Produced by Fiber Debonding and Pullout. AB - Fiber debonding and pullout are well-understood processes that occur during damage and failure events in composite materials. In this study, we show how these mechanisms, under controlled conditions, can be used to produce multifunctional textured surfaces. A two-step process consisting of (1) achieving longitudinal fiber alignment followed by (2) cutting, rearranging, and joining is used to produce the textured surfaces. This process employs common composite manufacturing techniques and uses no reactive chemicals or wet handling, making it suitable for scalability. This uniform textured surface is due to the fiber debonding and pullout occurring during the cutting process. Using well established fracture mechanics principles for composite materials, we demonstrate how different material parameters such as fiber geometry, fiber and matrix stiffness and strength, and interface behavior can be used to achieve multifunctional textured surfaces. The resulting textured surfaces show very high friction coefficients on wet ice (9* improvement), indicating their promising potential as materials for ice traction/tribology. Furthermore, the texturing enhances the surface's hydrophobicity as indicated by an increase in the contact angle of water by 30%. The substantial improvements to surface tribology and hydrophobicity make fiber debonding and pullout an effective, simple, and scalable method of producing multifunctional textured surfaces. PMID- 27714988 TI - Intranasal delivery of Natesto(r) testosterone gel and its effects on doping markers. AB - The laboratory profile of intranasal testosterone gel has not been previously reported from an anti-doping perspective. Because intranasal testosterone gel is newly available as a commercial product, we sought to examine the laboratory parameters following administration of this formulation, with particular attention to anti-doping guidelines. Five healthy and active male subjects were administered testosterone intranasal gel three times daily for four weeks, using a pattern of five consecutive days on, two days off. Urine was collected after each five-day round of drug administration and analyzed using a full steroid screen and isotope ratio mass spectrometry (IRMS). Windows of detection for elevated testosterone/epitestosterone (T/E) and other steroid ratios, World Anti Doping Agency (WADA) athlete biological passport (ABP) findings, and IRMS results were analyzed in this study. In the 0-24 h window post-administration, 70% of samples were flagged with a suspicious steroid profile and 85% were flagged as atypical passport findings according to the WADA ABP steroid module. In the 24-48 h window, 0% of samples displayed suspicious steroid profiles while 40% resulted in atypical passport findings. IRMS testing confirmed the presence of exogenous testosterone in 90% and 40% of samples in the 0-24 h and 24-48 h windows post administration, respectively. Additionally, IRMS data were analyzed to determine commonalities in the population changes in delta13 C values of testosterone, androsterone, etiocholanolone, 5alphaAdiol, and 5betaAdiol. Though no discernible metabolic trend of the route of administration was identified, we discovered that intranasal gel testosterone is detectable using conventional anti-doping tests.

PMID- 27714991 TI - Porous N-Doped Carbon Prepared from Triazine-Based Polypyrrole Network: A Highly Efficient Metal-Free Catalyst for Oxygen Reduction Reaction in Alkaline Electrolytes. AB - Metal-free N-doped carbon (NC) materials have been regarded as one of the most promising catalysts for the oxygen reduction reaction (ORR) in alkaline media because of their outstanding ORR catalytic activity, high stability, and good methanol tolerance. Up to now, only a small minority of such catalysts have been synthesized from triazine-based polymeric networks. Herein, we report the synthesis of such NC catalyst by directly pyrolyzing a nitrogen-rich, triazine based polypyrrole network (TPN). The TPN is fabricated by oxidative polymerization of 2,4,6-tripyrrol-1,3,5-triazine monomer using TfOH as the protonating agent and benzoyl peroxide as the oxidizing agent. The obtained NC 900 (pyrolyzed at 900 degrees C) catalyst exhibits excellent ORR activity in alkaline media with a high ORR onset potential (0.972 V vs RHE), a large kinetic limiting current density (15.66 mA cm-2 at 0.60 V), and good MeOH tolerance and durability. The as-synthesized NC-900 material is a potential candidate as a highly active, stable, and low-cost ORR catalyst for alkaline fuel cells. PMID- 27714992 TI - Single Molecule Nanoelectrochemistry in Electrical Junctions. AB - It is now possible to reliably measure single molecule conductance in a wide variety of environments including organic liquids, ultrahigh vacuum, water, ionic liquids, and electrolytes. The most commonly used methods deploy scanning probe microscopes, mechanically formed break junctions, or lithographically formed nanogap contacts. Molecules are generally captured between a pair of facing electrodes, and the junction current response is measured as a function of bias voltage. Gating electrodes can also be added so that the electrostatic potential at the molecular bridge can be independently controlled by this third noncontacting electrode. This can also be achieved in an electrolytic environment using a four-electrode bipotentiostatic configuration, which allows independent electrode potential control of the two contacting electrodes. This is commonly realized using an electrochemical STM and enables single molecule electrical characterization as a function of electrode potential and redox state of the molecular bridge. This has emerged as a powerful tool in modern interfacial electrochemistry and nanoelectrochemistry for studying charge transport across single molecules as a function of electrode potential and the electrolytic environments. Such measurements are possible in electrolytes ranging from aqueous buffers to nonaqueous ionic liquids. In this Account, we illustrate a number of examples of single molecule electrical measurements under electrode potential control use a scanning tunneling microscope (STM) and demonstrate how these can help in the understanding of charge transport in single molecule junctions. Examples showing charge transport following phase coherent tunneling to incoherent charge hopping across redox active molecular bridges are shown. In the case of bipyridinium (or viologen) molecular wires, it is shown how electrochemical reduction leads to an increase of the single molecule conductance, which is controlled by the liquid electrochemical gating. This has been referred to as to a "single molecule transistor configuration" with the gate voltage being provided by the controllable potential achieved through the electrochemical double layer. It is shown how the electrolyte medium can control such gating, with ionic liquids providing more efficient gate coupling than aqueous electrolytes. Control of the conductance of viologen molecular wires can also be achieved by encapsulating the viologen redox moiety within a molecular cage, thereby controlling its immediate environment. Molecular conductance can also be gated through multiple redox states. This has been shown for the redox moiety pyrrolo-tetrathiafulvalene, which undergoes single molecule electrochemical transistor gating through three redox states in molecular junctions. Charge transport through this junction follows a two-step hopping mechanism, demonstrating the role of the redox center in electron transfer across the molecular bridge. Recent electrolyte gating studies of rigid, conjugated redox-active metal complexes with tailored terpyridine coordinating ligands and anchors are also presented. These aforementioned studies have all been performed with gold electrode contacts. The Account concludes with recent data showing that it is now possible to study single molecule electrochemical gating with nickel electrodes. This opens up new perspectives for studying interfacial charge transfer with a wide variety of other electrode materials including semiconductor electrodes and also points toward future opportunities for coupling molecular spintronics and nanoelectrochemistry. PMID- 27714993 TI - Colorimetric Logic Gate for Pyrophosphate and Pyrophosphatase via Regulating the Catalytic Capability of Horseradish Peroxidase. AB - By regulating the catalytic capability of horseradish peroxidase (HRP), an artful colorimetric assay platform for pyrophosphate (PPi) and pyrophosphatase (PPase) was unprecedentedly designed. In this work, Cu(I), generated by reducing Cu(II) in the presence of ascorbate, could inhibit HRP's catalytic capability of transforming colorless 3,3',5,5'-tetramethylbenzidine (TMB) into blue oxidized TMB (oxTMB). The robust coordination between PPi and Cu(II) is able to discourage the reduction of Cu(II) to Cu(I) effectively, thus restoring the original catalytic capability of HRP and regenerating blue-colored oxTMB. Upon PPase introduction, PPi would be hydrolyzed into orthophosphate, which could release Cu(II) free from the Cu(II)-PPi complex, and thus in turn allows the catalytic capability of HRP to be inhibited by Cu(I). HRP was activated or deactivated to different degrees depending on PPi or PPase levels, which could be indicated by using HRP-triggered catalytic system as a signal amplifier, thus paving a way for PPi and PPase sensing. Based on the colorimetric sensor for PPi and PPase, an "INH" logic gate was rationally constructed. With the merits of high sensitivity and selectivity, cost-effectiveness, and simplification, our proposed analytical system has also been verified to have potential to be utilized for enzyme inhibitor screening and diagnosis of PPase-related diseases. PMID- 27714994 TI - Surface-Independent Hierarchical Coatings with Superamphiphobic Properties. AB - Facile approaches for the fabrication of substrate independent superamphiphobic surfaces that can repel both water and organic liquids have been limited. The design of such super-repellent surfaces is still a major challenge of surface chemistry and physics. Herein, we describe a simple and efficient dip-coating approach for the fabrication of highly hierarchical surface coatings with superamphiphobic properties for a broad range of materials based on a mussel inspired dendritic polymer (MI-dPG). The MI-dPG coating process provides a precise roughness control, and the construction of highly hierarchical structures was achieved either directly by pH-controlled aggregation or in combination with nanoparticles (NP). Moreover, the fabrication of coatings with a thickness and roughness gradient was possible via simple adjustment of the depth of the coating solution. Subsequent postmodification of these highly hierarchical structures with fluorinated molecules yielded a surface with superamphiphobic properties that successfully prevented the wetting of liquids with a low surface tension down to about 30 mN/m. The generated superamphiphobic coatings exhibit impressive repellency to water, surfactant containing solutions, and biological liquids, such as human serum, and are flexible on soft substrates.

AB - Flexible microsupercapacitors (MSCs) are needed to power ultrasmall wearable electronic devices. Silk cocoons comprise microfibers of silk, which is an attractive natural resource to fabricate MSCs. These fibers are insulators; hence, they must be converted to conducting surfaces. Polyphenols from green tea have been used as a protective layer that also acted as a reducing agent for silver ions. The reduction of silver ions resulted in the formation of silver nanoparticles that subsequently reduced gold ions to gold. The gold film imparts conductivity to the silk fiber without affecting the mechanical strength of the silk fiber. The mechanical strength of uncoated silk fiber and gold coated silk fiber were found to be 5.2 and 5 GPa, respectively. A pseudocapacitive polymer, poly(3,4-ethylenedioxythiophene), was used as the active material to fabricate MSCs. The MSCs showed an impressive gravimetric capacitance of 500 F/g and areal capacitance of 62 mF/cm2. The power and energy densities were calculated to be 2458 W/kg and 44 Wh/kg, respectively. The device was coiled on a cylinder, and the performance of the device was found to be same as that of the uncoiled device. To demonstrate that the approach is not specific to silk, we also coated gold on cotton fibers using the protocol used to coat gold on silk. Coiled and uncoiled supercapacitors were fabricated using PEDOT coated cotton fibers. The gravimetric capacitance was found to be 250 F/g with energy and power densities of 5.5 Wh/kg and 1118 W/kg, respectively. We have also demonstrated that the devices can be connected in parallel and series to improve the performance of the miniaturized devices. PMID- 27714997 TI - Surfaces Mimicking Glycosaminoglycans Trigger Different Response of Stem Cells via Distinct Fibronectin Adsorption and Reorganization. AB - We report on the utility of a platform created by self-assembled monolayers to investigate the influence of the degree of sulfation of glycosaminoglycans (GAGs) on their interactions with fibronectin (Fn) and the impact of these interactions on the adhesion and morphology of human adipose derived stem cells (ASCs). We used the label-free QCM-D, AFM and SPR to follow the changes in the protein adlayer in close proximity to the substrates surface and QCM-D in combination with live imaging to characterize the adherent cells. Our results suggest that Fn interactions with GAGs are governed by both H-bonding and electrostatic forces. Strong electrostatic interactions cause irreversible change in the protein conformation, while the weaker H-bonding only partially restricts the protein flexibility, allowing Fn reorganization and exposure of its binding sites for ASC adhesion. These findings imply that a delicate balance between these two types of forces must be considered in the design of biomaterials that mimic GAGs. PMID- 27714998 TI - Prominent Vascularization Capacity of Mesenchymal Stem Cells in Collagen-Gold Nanocomposites. AB - The ideal characteristics of surface modification on the vascular graft for clinical application would be with excellent hemocompatibility, endothelialization capacity, and antirestenosis ability. Here, Fourier transform infrared spectroscopy (FTIR), surface enhanced Raman spectroscopy (SERS), atomic force microscopy (AFM), contact angle (theta) measurement, and thermogravimetric analysis (TGA) were used to evaluate the chemical and mechanical properties of collagen-gold nanocomposites (collagen+Au) with 17.4, 43.5, and 174 ppm of Au and suggested that the collagen+Au with 43.5 ppm of Au had better biomechanical properties and thermal stability than pure collagen. Besides, stromal-derived factor-1alpha (SDF-1alpha) at 50 ng/mL promoted the migration of mesenchymal stem cells (MSCs) on collagen+Au material through the alpha5beta3 integrin/endothelial oxide synthase (eNOS)/metalloproteinase (MMP) signaling pathway which can be abolished by the knockdown of vascular endothelial growth factor (VEGF). The potentiality of collagen+Au with MSCs for vascular regeneration was evaluated by our in vivo rat model system. Artery tissues isolated from an implanted collagen+Au-coated catheter with MSCs expressed substantial CD-31 and alpha-SMA, displayed higher antifibrotic ability, antithrombotic activity, as well as anti inflammatory response than all other materials. Our results indicated that the implantation of collagen+Au-coated catheters with MSCs could be a promising strategy for vascular regeneration. PMID- 27714999 TI - Potassium Secondary Batteries. AB - Potassium may exhibit advantages over lithium or sodium as a charge carrier in rechargeable batteries. Analogues of Prussian blue can provide millions of cyclic voltammetric cycles in aqueous electrolyte. Potassium intercalation chemistry has recently been demonstrated compatible with both graphite and nongraphitic carbons. In addition to potassium-ion batteries, potassium-O2 (or -air) and potassium-sulfur batteries are emerging. Additionally, aqueous potassium-ion batteries also exhibit high reversibility and long cycling life. Because of potentially low cost, availability of basic materials, and intriguing electrochemical behaviors, this new class of secondary batteries is attracting much attention. This mini-review summarizes the current status, opportunities, and future challenges of potassium secondary batteries. PMID- 27715001 TI - Hybrid Thin Film Organosilica Sol-Gel Coatings To Support Neuronal Growth and Limit Astrocyte Growth. AB - Thin films of silica prepared by a sol-gel process are becoming a feasible coating option for surface modification of implantable neural sensors without imposing adverse effects on the devices' electrical properties. In order to advance the application of such silica-based coatings in the context of neural interfacing, the characteristics of silica sol-gel are further tailored to gain active control of interactions between cells and the coating materials. By incorporating various readily available organotrialkoxysilanes carrying distinct organic functional groups during the sol-gel process, a library of hybrid organosilica coatings is developed and investigated. In vitro neural cultures using PC12 cells and primary cortical neurons both reveal that, among these different types of hybrid organosilica, the introduction of aminopropyl groups drastically transforms the silica into robust neural permissive substrate, supporting neuron adhesion and neurite outgrowth. Moreover, when this organosilica is cultured with astrocytes, a key type of glial cells responsible for glial scar response toward neural implants, such cell growth promoting effect is not observed. These findings highlight the potential of organo-group-bearing silica sol-gel to function as advanced coating materials to selectively modulate cell response and promote neural integration with implantable sensing devices. PMID- 27715000 TI - Hybrid n-Alkylamine Intercalated Layered Titanates for Solid Lubrication. AB - The intercalation of different primary n-alkylamines in the structure of a layered titanate of the lepidocrocite type (H1.07Ti1.73O4) for application in high-temperature solid lubrication is reported. The intercalation process of the amines was explored by means of in situ small-angle X-ray scattering (SAXS), with variations in alkyl chain length (3-12 carbon atoms) and the amine/titanate ratio. The intercalation process was found to be completed within 5 min after mixing of the precursors in water at 80 degrees C. The topotactic transformation of the layered titanate is driven by an acid-base reaction. The thermal degradation of the modified titanates was investigated by thermogravimetric analysis (TGA), and the chemical changes were investigated by temperature dependent infrared spectroscopy (DRIFTS). The coefficient of friction of the lubricants was assessed by means of high-temperature pin-on-disc experiments up to 580 degrees C. The intercalation of amine rendered a deformable layered ceramic upon heating. It was found that the hydrocarbon chain length exerts an influence on the mechanical properties of the titanates, resulting in lower friction forces for lubricants with longer intercalated amine molecules. Films of solid lubricants with longer amine chain lengths showed coefficients of friction as low as 0.01, lower than that of the state-of-the-art material graphite. PMID- 27715002 TI - Dominant Factors Governing the Electron Transfer Kinetics and Electrochemical Biosensing Properties of Carbon Nanofiber Arrays. AB - Carbon-based electrodes have been widely used in electroanalysis for more than half a century, but the factors governing the heterogeneous electron-transfer (HET) rate are still unclear. The effects of the exposed edge plane site density, inherent resistance of the carbon electrode, and adjustable resistors on the HET kinetics of several outer- and inner-sphere redox couples including [Fe(CN)6]3-/4 , Ru(NH3)63+/2+, Fe3+/2+, dopamine, ascorbic acid, and uric acid are investigated using three kinds of carbon electrodes composed of core-shell quasi-aligned nanofiber arrays (QANFAs). The internal resistance is found to be a key factor affecting the HET kinetics and electrochemical biosensing properties. The electrodes exhibit high selectivity and sensitivity in dopamine detection in the presence of ascorbic acid and uric acid. In addition to the promising application to electrochemical biosensing, the core-shell TiC/C QANFAs encompassing a highly electroactive carbon shell and conductive TiC core provide insights into the design and construction of the ideal carbon electrode. PMID- 27715003 TI - Three-Dimensional Porous Graphene Aerogel Cathode with High Sulfur Loading and Embedded TiO2 Nanoparticles for Advanced Lithium-Sulfur Batteries. AB - Three-dimensional graphene aerogel/TiO2/sulfur (GA/TiO2/S) composites are synthesized through a facile, one-pot hydrothermal route as the cathode for lithium-sulfur batteries. With a high sulfur content of 75.1 wt %, the conductive, highly porous composite electrode delivers a high discharge capacity of 512 mA h/g after 250 cycles at a current rate of 1 C with a low capacity decay of 0.128% per cycle. The excellent capacities and cyclic stability arise from several unique functional features of the cathode. (i) The conductive graphene aerogel framework ameliorates ion/electron transfer while accommodating the volume expansion induced during discharge, and (ii) TiO2 nanoparticles play an important role in restricting the dissolution of polysulfides by chemical bonds with sulfur. PMID- 27715004 TI - Biofilm Impeding AgNPs Target Skin Carcinoma by Inducing Mitochondrial Membrane Depolarization Mediated through ROS Production. AB - Reactive oxygen species (ROS) are a double-edged sword that possesses both beneficial and harmful effects. Although basic research on skin cancer prevention has undergone a huge transformation, cases of recurrence with higher rates of drug resistance are some of its drawbacks. Therefore, targeting mitochondria by ROS overproduction provides an alternate approach for anticancer therapy. In the present study, green-synthesized silver nanoparticles (AgNPs) were explored for triggering the ROS production in A431 skin carcinoma cells. The synthesized AgNPs were characterized for size, charge, morphology, and phase through high throughput DLS, Fe-SEM, XRD, and ATR-FTIR techniques. Their physiochemical properties with hemoglobin and blood plasma were screened through hemolysis, hemagglutination assay, and circular dichroism spectroscopy confirmed their nontoxic nature. The AgNPs also exhibited additional efficacy in inhibiting biofilm produced by V. cholerae and B. subtilis, thereby facilitating better applicability in wound-healing biomaterials. The depolarization of mitochondrial membrane potential DeltaPsim through excess ROS production was deduced to be the triggering force behind the apoptotic cell death mechanism of the skin carcinoma. Subsequent experimentation through DNA fragmentation, comet tail formation, cell membrane blebbing, and reduced invasiveness potentials through scratch assay confirmed the physiological hallmarks of apoptosis. Thus, depolarizing mitochondrial membrane potential through green-synthesized AgNPs provides an economic, nontoxic, specific approach for targeting skin carcinoma with additional benefits of antibacterial activities. PMID- 27715005 TI - Thermal Diffusivity of Single Carbon Nanocoil: Uncovering the Correlation with Temperature and Domain Size. AB - As an exotic class of low-dimensional carbon nanostructures, carbon nanocoils' (CNCs) helical geometries and polycrystalline-amorphous structure distinguish them from carbon nanotubes and graphene. These distinct structures result in very much different energy transport from that in carbon nanotubes and graphene, leading to important roles in applications as wave absorbers, near-infrared sensors, and nano-electromechanical sensors. Here we report a systematic study of the thermal diffusivity (alpha) and conductivity (kappa) of CNCs from 290 to 10 K, and uncover their property-structure aspects. Our room temperature alpha study reveals an correlation between alpha and the line diameter (d): alpha=(5.43 *104e d/37.7+9.5)*10-7 m2/s. Combined with the Raman-based grain size (La) characterization, alpha and La are correlated as alpha=[81.2*(La-3.32)1.5+9.5] *10-7 m2/s. With temperature decreasing from 290 to 10 K, alpha has a 1~1.6-fold increase, and kappa shows a peak around 75 K. To best understand the defect level and polycrystalline-amorphous structure of CNCs, the thermal reffusivity (Theta=alpha-1) of CNCs is studied and compared with that of graphite and graphene foam from 290 K down to 10 K. Very interestingly, CNC's Theta linearly decreases with decreased temperature while Theta of graphite and graphene foam have an exponential decrease. The extrapolated 0 K-limit Theta is determined by low-momentum phonon scattering, and gives a structure domain size of CNC samples (d=455, 353, and 334 nm) as 1.28 nm, 2.03 nm and 3.24 nm. These sizes are coherent with the x-ray diffraction results (3.5 nm) and the Raman spectroscopy study, and confirm the correlation among d, La, and alpha. PMID- 27715006 TI - Van der Waals Epitaxy of GaSe/Graphene Heterostructure: Electronic and Interfacial Properties. AB - Stacking two-dimensional materials in so-called van der Waals (vdW) heterostructures, like the combination of GaSe and graphene, provides the ability to obtain hybrid systems which are suitable to design optoelectronic devices. Here, we report the structural and electronic properties of the direct growth of multilayered GaSe by Molecular beam Epitaxy (MBE) on graphene. Reflection high energy electron diffraction (RHEED) images exhibited sharp streaky features indicative of high quality GaSe layer produced via a vdW epitaxy. Micro-Raman spectroscopy showed that, after the vdW hetero-interface formation, the Raman signature of pristine graphene is preserved. However, the GaSe film tuned the charge density of graphene layer by shifting the Dirac point by about 80 meV toward lower binding energies, attesting an electron transfer from graphene to GaSe. Angle-resolved photoemission spectroscopy (ARPES) measurements showed that the maximum of the valence band of few layers of GaSe are located at the Gamma point at a binding energy of about -0.73 eV relatively to the Fermi level (p-type doping). From the ARPES measurements, a hole effective mass defined along the GammaM direction and equal to about m*/m0 = -1.1 was determined. By coupling the ARPES data with high resolution X-ray photoemission spectroscopy (HR-XPS) measurements, the Schottky interface barrier height was estimated to be 1.2 eV. These findings allow deeper understanding of the interlayer interactions and the electronic structure of GaSe/graphene vdW heterostructure. PMID- 27715007 TI - Dopamine D3/D2 Receptor Antagonist PF-4363467 Attenuates Opioid Drug-Seeking Behavior without Concomitant D2 Side Effects. AB - Dopamine receptor antagonism is a compelling molecular target for the treatment of a range of psychiatric disorders, including substance use disorders. From our corporate compound file, we identified a structurally unique D3 receptor (D3R) antagonist scaffold, 1. Through a hybrid approach, we merged key pharmacophore elements from 1 and D3 agonist 2 to yield the novel D3R/D2R antagonist PF-4363467 (3). Compound 3 was designed to possess CNS drug-like properties as defined by its CNS MPO desirability score (>=4/6). In addition to good physicochemical properties, 3 exhibited low nanomolar affinity for the D3R (D3 Ki = 3.1 nM), good subtype selectivity over D2R (D2 Ki = 692 nM), and high selectivity for D3R versus other biogenic amine receptors. In vivo, 3 dose-dependently attenuated opioid self-administration and opioid drug-seeking behavior in a rat operant reinstatement model using animals trained to self-administer fentanyl. Further, traditional extrapyramidal symptoms (EPS), adverse side effects arising from D2R antagonism, were not observed despite high D2 receptor occupancy (RO) in rodents, suggesting that compound 3 has a unique in vivo profile. Collectively, our data support further investigation of dual D3R and D2R antagonists for the treatment of drug addiction. PMID- 27715008 TI - Greatly Increasing Trapped Ion Populations for Mobility Separations Using Traveling Waves in Structures for Lossless Ion Manipulations. AB - The initial use of traveling waves (TW) for ion mobility (IM) separations using structures for lossless ion manipulations (SLIM) employed an ion funnel trap (IFT) to accumulate ions from a continuous electrospray ionization source and was limited to injected ion populations of ~106 charges due to the onset of space charge effects in the trapping region. Additional limitations arise due to the loss of resolution for the injection of ions over longer periods, such as in extended pulses. In this work a new SLIM "flat funnel" (FF) module has been developed and demonstrated to enable the accumulation of much larger ion populations and their injection for IM separations. Ion current measurements indicate a capacity of ~3.2 * 108 charges for the extended trapping volume, over an order of magnitude greater than that of the IFT. The orthogonal ion injection into a funnel shaped separation region can greatly reduce space charge effects during the initial IM separation stage, and the gradually reduced width of the path allows the ion packet to be increasingly compressed in the lateral dimension as the separation progresses, allowing efficient transmission through conductance limits or compatibility with subsequent ion manipulations. This work examined the TW, rf, and dc confining field SLIM parameters involved in ion accumulation, injection, transmission, and IM separation in the FF module using both direct ion current and MS measurements. Wide m/z range ion transmission is demonstrated, along with significant increases in the signal-to-noise ratios (S/N) due to the larger ion populations injected. Additionally, we observed a reduction in the chemical background, which was attributed to more efficient desolvation of solvent related clusters over the extended ion accumulation periods. The TW SLIM FF IM module is anticipated to be especially effective as a front end for long path SLIM IM separation modules. PMID- 27715009 TI - Crystal Structure of Os79 (Os04g0206600) from Oryza sativa: A UDP glucosyltransferase Involved in the Detoxification of Deoxynivalenol. AB - Fusarium head blight is a plant disease with significant agricultural and health impact which affects cereal crops such as wheat, barley, and maize and is characterized by reduced grain yield and the accumulation of trichothecene mycotoxins such as deoxynivalenol (DON). Studies have identified trichothecene production as a virulence factor in Fusarium graminearum and have linked DON resistance to the ability to form DON-3-O-glucoside in wheat. Here, the structures of a deoxynivalenol:UDP-glucosyltransferase (Os79) from Oryza sativa are reported in complex with UDP in an open conformation, in complex with UDP in a closed conformation, and in complex with UDP-2-fluoro-2-deoxy-d-glucose and trichothecene at 1.8, 2.3, and 2.2 A resolution, respectively. The active site of Os79 lies in a groove between the N-terminal acceptor and the C-terminal donor binding domains. Structural alignments reveal that Os79 likely utilizes a catalytic mechanism similar to those of other plant UGTs, with His 27 activating the trichothecene O3 hydroxyl for nucleophilic attack at C1' of the UDP-glucose donor. Kinetic analysis of mutant Os79 revealed that Thr 291 plays a critical role in catalysis as a catalytic acid or to position the UDP moiety during the nucleophilic attack. Steady-state kinetic analysis demonstrated that Os79 conjugates multiple trichothecene substrates such as DON, nivalenol, isotrichodermol, and HT-2 toxin, but not T-2 toxin. These data establish a foundation for understanding substrate specificity and activity in this enzyme and can be used to guide future efforts to increase DON resistance in cereal crops. PMID- 27715011 TI - Optimization of Surface-Enhanced Raman Spectroscopy Conditions for Implementation into a Microfluidic Device for Drug Detection. AB - A microfluidic device is being developed by University of California-Santa Barbara as part of a joint effort with the United States Army to develop a portable, rapid drug detection device. Surface-enhanced Raman spectroscopy (SERS) is used to provide a sensitive, selective detection technique within the microfluidic platform employing metallic nanoparticles as the SERS medium. Using several illicit drugs as analytes, the work presented here describes the efforts of the Edgewood Chemical Biological Center to optimize the microfluidic platform by investigating the role of nanoparticle material, nanoparticle size, excitation wavelength, and capping agents on the performance, and drug concentration detection limits achievable with Ag and Au nanoparticles that will ultimately be incorporated into the final design. This study is particularly important as it lays out a systematic comparison of limits of detection and potential interferences from working with several nanoparticle capping agents-such as tannate, citrate, and borate-which does not seem to have been done previously as the majority of studies only concentrate on citrate as the capping agent. Morphine, cocaine, and methamphetamine were chosen as test analytes for this study and were observed to have limits of detection (LOD) in the range of (1.5 4.7) * 10-8 M (4.5-13 ng/mL), with the borate capping agent having the best performance. PMID- 27715010 TI - Combined Measurement of 6 Fat-Soluble Vitamins and 26 Water-Soluble Functional Vitamin Markers and Amino Acids in 50 MUL of Serum or Plasma by High-Throughput Mass Spectrometry. AB - Targeted metabolic profiling characterized by complementary platforms, multiplexing and low volume consumption are increasingly used for studies using biobank material. Using liquid-liquid extraction, we developed a sample workup suitable for quantification of 6 fat- and 26 water-soluble biomarkers. 50 MUL of serum/plasma was mixed with dithioerythritol, ethanol, and isooctane/chloroform. The organic layer was used for analysis of the fat-soluble vitamins all-trans retinol (A), 25-hydroxyvitamin D2, 25-hydroxyvitamin D3, alpha-tocopherol (E), gamma-tocopherol (E), and phylloquinone (K1) by LC-MS/MS. The remaining aqueous fraction was mixed with ethanol, water, pyridine, and methylchloroformate (in toluene) to derivatize the water-soluble biomarkers. The resulting toluene layer was used for GC-MS/MS analysis of alanine, alpha-ketoglutarate, asparagine, aspartic acid, cystathionine, total cysteine, glutamic acid, glutamine, glycine, histidine, total homocysteine, isoleucine, kynurenine, leucine, lysine, methionine, methylmalonic acid, ornithine, phenylalanine, proline, sarcosine, serine, threonine, tryptophan, tyrosine, and valine. Isotope-labeled internal standards were used for all analytes. Chromatographic run times for the LC-MS/MS and GC-MS/MS were 4.5 and 11 min, respectively. The limits of detection (LOD) for the low-concentration analytes (25-hydroxyvitamin D2, 25-hydroxyvitamin D3, and phylloquinone) were 25, 17, and 0.33 nM, respectively, while all other analytes demonstrated sensitivity significantly lower than endogenous concentrations. Recoveries ranged from 85.5-109.9% and within- and between-day coefficients of variance (CVs) were 0.7-9.4% and 1.1-17.5%, respectively. This low-volume, high throughput multianalyte assay is currently in use in our laboratory for quantification of 32 serum/plasma biomarkers in epidemiological studies. PMID- 27715012 TI - Anaerobic Disposal of Arsenic-Bearing Wastes Results in Low Microbially Mediated Arsenic Volatilization. AB - The removal of arsenic from drinking water sources produces arsenic-bearing wastes, which are disposed of in a variety of ways. Several disposal options involve anaerobic environments, including mixing arsenic waste with cow dung, landfills, anaerobic digesters, and pond sediments. Though poorly understood, the production of gaseous arsenic species in these environments can be a primary goal (cow dung mixing) or an unintended consequence (anaerobic digesters). Once formed, these gaseous arsenic species are readily diluted in the atmosphere. Arsenic volatilization can be mediated by the enzyme arsenite S adenosylmethionine methyltransferase (ArsM) or through the enzymes involved in methanogenesis. In this study, methanogenic mesocosms with arsenic-bearing ferric iron waste from an electrocoagulation drinking water treatment system were used to evaluate the role of methanogenesis in arsenic volatilization using methanogen inhibitors. Arsenic volatilization was highest in methanogenic mesocosms, but represented <0.02% of the total arsenic added. 16S rRNA cDNA sequencing, qPCR of mcrA transcripts, and functional gene array-based analysis of arsM expression, revealed that arsenic volatilization correlated with methanogenic activity. Aqueous arsenic concentrations increased in all mesocosms, indicating that unintended contamination may result from disposal in anaerobic environments. This highlights that more research is needed before recommending anaerobic disposal intended to promote arsenic volatilization. PMID- 27715013 TI - Functionalization of Ultrabithorax Materials with Vascular Endothelial Growth Factor Enhances Angiogenic Activity. AB - Successful design of tissue engineering scaffolds must include the ability to stimulate vascular development by incorporating angiogenic growth factors. Current approaches can allow diffusion of growth factors, incorporate active factors randomly, or can leave residual toxins. We addressed these problems by genetically fusing the gene encoding Vascular Endothelial Growth Factor (VEGF) with the Ultrabithorax (Ubx) gene to produce fusion proteins capable of self assembly into materials. We demonstrate that VEGF-Ubx materials enhance human endothelial cell migration, prolong cell survival, and dose-dependently activate the VEGF signaling pathway. VEGF-Ubx fibers attract outgrowing sprouts in an aortic ring assay and induce vessel formation in a chicken embryo chorioallantoic membrane (CAM) assay. Collectively, these results demonstrate that the activity of VEGF remains intact in Ubx materials. This approach could provide an inexpensive and facile mechanism to stimulate and pattern angiogenesis. PMID- 27715014 TI - Ratiometric Fluorescent Biosensing of Hydrogen Peroxide and Hydroxyl Radical in Living Cells with Lysozyme-Silver Nanoclusters: Lysozyme as Stabilizing Ligand and Fluorescence Signal Unit. AB - Construction of facile ratiometric fluorescent probes which possess sensitive and selective sensing ability for bioactive small molecules is highly desirable and challenging. Herein, silver nanoclusters capped with denatured lysozyme (dLys AgNCs) were synthesized and proved to be dual emissive. The facility of the dLys AgNCs ratiometric probe was attributed to the finding that the lysozyme acted not only as stabilizing ligand but also as fluorescence signal unit. In the presence of Fenton reagents, the emission of dLys-AgNCs at 640 nm was quenched by *OH, whereas the emission at 450 was enhanced due to *OH-induced oxidation of tyrosine in the lysozyme. This probe could be used for highly sensitive detection of H2O2. The fluorescence changes of F450/F640 had fantastic linearity to H2O2 concentrations in the range of 0.8-200 MUmol/L (R2 = 0.9993), with a limit of detection (LOD) as low as 0.2 MUmol/L. Additionally, this probe was also applied to H2O2-generated oxidase-based biosensing. As a proof-of-concept, glucose and acetylcholine chloride were detected with benefical LOD values of 0.6 MUmol/L and 0.8 MUmol/L, respectively. Furthermore, fluorescence confocal imaging demonstrated dLys-AgNCs had a sensitive response to fluctuation of *OH levels in living cells, which might have promising application in study of *OH-induced oxidative damage to proteins. PMID- 27715015 TI - Enhancement of Compound Selectivity Using a Radio Frequency Ion-Funnel Proton Transfer Reaction Mass Spectrometer: Improved Specificity for Explosive Compounds. AB - A key issue with any analytical system based on mass spectrometry with no initial separation of compounds is to have a high level of confidence in chemical assignment. This is particularly true for areas of security, such as airports, and recent terrorist attacks have highlighted the need for reliable analytical instrumentation. Proton transfer reaction mass spectrometry is a useful technology for these purposes because the chances of false positives are small owing to the use of a mass spectrometric analysis. However, the detection of an ion at a given m/z for an explosive does not guarantee that that explosive is present. There is still some ambiguity associated with any chemical assignment owing to the presence of isobaric compounds and, depending on mass resolution, ions with the same nominal m/z. In this article we describe how for the first time the use of a radio frequency ion-funnel (RFIF) in the reaction region (drift tube) of a proton transfer reaction-time-of-flight-mass spectrometer (PTR-ToF-MS) can be used to enhance specificity by manipulating the ion-molecule chemistry through collisional induced processes. Results for trinitrotoluene, dinitrotoluenes, and nitrotoluenes are presented to demonstrate the advantages of this new RFIF-PTR-ToF-MS for analytical chemical purposes. PMID- 27715016 TI - Differential Mobility Spectrometry for Inorganic Filtration in Nuclear Forensics. AB - Differential mobility spectrometry (DMS) is applied to the analysis of inorganic mixtures relevant to nuclear forensics. Three primary components of potential radiological dispersal devices (RDDs), cobalt, cesium, and strontium, were studied by DMS to demonstrate rapid sample cleanup when coupled to mass spectrometry. Nanosprayed salt solutions comprised of stable analogs, as proxies to these radioisotopes, and isobaric interferents were introduced to DMS. The DMS effluent was directly coupled to a mass spectrometer to confirm the elemental identity of the separated clusters. DMS dispersion plots demonstrated distinctive elemental separation from both atomic and molecular interferents. These results support the potential use of DMS as a means of rapid separation for inorganic analyses prior to analysis in a field portable mass spectrometer. The mechanism for this process is speculated to involve dynamics of solvent cluster formation under the influence of the alternating high and low electric fields of the DMS. PMID- 27715017 TI - Radiosynthesis and Preclinical Evaluation of 18F-Fluoroglycosylated Octreotate for Somatostatin Receptor Imaging. AB - Short synthetic octapeptide analogs derived from the native somatostatin peptides SST-14 and SST-28, namely, octreotate (TATE) or octreotide (TOC), bind with high affinity to somatostatin receptors (sstr), mainly to subtypes 2 and 5, which are expressed in high density on neuroendocrine tumors (NET). Therefore, radiolabeled TATE or TOC derivatives represent highly valuable imaging probes for NET diagnosis by positron emission tomography (PET). The aim of our study was the development of an 18F-labeled octreotate analog as an alternative radiotracer for the clinically established 68Ga-DOTATOC and 68Ga-DOTATATE. We applied our previously developed method based on copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) to the radiosynthesis of 18F-fluoroglycosylated TATE ([18F]FGlc-TATE). [18F]FGlc-TATE was obtained in high yields of 19-22% (non-decay corrected, referred to [18F]fluoride) and in high specific activities of 32-106 GBq/MUmol. [18F]FGlc-TATE showed high affinity to sstr expressed on AR42J cells (IC50 = 4.2 nM) with fast and high internalization, and a beneficial logD7.4 of 1.8. In AR42J tumor bearing nude mice, [18F]FGlc-TATE showed high and specific tumor uptake of 5.6%ID/g at 60 min post-injection, as determined by blocking experiments using octreotide, and fast clearance from other organs, resulting in excellent tumor-to-blood ratios increasing from 9 to 17 from 30 to 60 min post injection. Small animal PET studies revealed high uptake of [18F]FGlc-TATE in the tumor which could be blocked with octreotide by >99%. Overall, [18F]FGlc-TATE revealed excellent in vitro and in vivo properties and is therefore a viable alternative 18F-labeled radiopeptide for imaging somatostatin receptor-positive tumors by PET. PMID- 27715018 TI - Mechanistic Design of Chemically Diverse Polymers with Applications in Oral Drug Delivery. AB - Polymers play a key role in stabilizing amorphous drug formulations, a recent strategy employed to improve solubility and bioavailability of drugs delivered orally. However, the molecular mechanism of stabilization is unclear, therefore, the rational design of new crystallization-inhibiting excipients remains a substantial challenge. This article presents a combined experimental and computational approach to elucidate the molecular features that improve the effectiveness of cellulose polymers as solution crystallization inhibitors, a crucial first step toward their rational design. Polymers with chemically diverse substituents including carboxylic acids, esters, ethers, alcohols, amides, amines, and sulfides were synthesized. Measurements of nucleation induction times of the model drug, telaprevir, show that the only effective polymers contained carboxylate groups in combination with an optimal hydrocarbon chain length. Computational results indicate that polymer conformation as well as solvation free energy are important determinants of effectiveness at inhibiting crystallization and show that simulations are a promising predictive tool in the screening of polymers. This study suggests that polymers need to have an adequate hydrophilicity to promote solvation in an aqueous environment, and sufficient hydrophobic regions to drive interactions with the drug. Particularly, the right balance between key substituent groups and lengths of hydrocarbon side chains is needed to create effective materials. PMID- 27715019 TI - Land Use in LCA: Including Regionally Altered Precipitation to Quantify Ecosystem Damage. AB - The incorporation of soil moisture regenerated by precipitation, or green water, into life cycle assessment has been of growing interest given the global importance of this resource for terrestrial ecosystems and food production. This paper proposes a new impact assessment model to relate land and water use in seasonally dry, semiarid, and arid regions where precipitation and evapotranspiration are closely coupled. We introduce the Precipitation Reduction Potential midpoint impact representing the change in downwind precipitation as a result of a land transformation and occupation activity. Then, our end-point impact model quantifies terrestrial ecosystem damage as a function of precipitation loss using a relationship between woody plant species richness, water and energy regimes. We then apply the midpoint and end-point models to the production of soybean in Southeastern Amazonia which has resulted from the expansion of cropland into tropical forest, with noted effects on local precipitation. Our proposed cause-effect chain represents a complementary approach to previous contributions which have focused on water consumption impacts and/or have represented evapotranspiration as a loss to the water cycle. PMID- 27715020 TI - Marine Phages As Tracers: Effects of Size, Morphology, and Physico-Chemical Surface Properties on Transport in a Porous Medium. AB - Although several studies examined the transport of viruses in terrestrial systems only few studies exist on the use of marine phages (i.e., nonterrestrial viruses infecting marine host bacteria) as sensitively detectable microbial tracers for subsurface colloid transport and water flow. Here, we systematically quantified and compared for the first time the effects of size, morphology and physicochemical surface properties of six marine phages and two coliphages (MS2, T4) on transport in sand-filled percolated columns. Phage-sand interactions were described by colloidal filtration theory and the extended Derjaguin-Landau-Verwey Overbeek approach (XDLVO), respectively. The phages belonged to different families and comprised four phages never used in transport studies (i.e., PSA HM1, PSA-HP1, PSA-HS2, and H3/49). Phage transport was influenced by size, morphology and hydrophobicity in an approximate order of size > hydrophobicity >= morphology. Two phages PSA-HP1, PSA-HS2 (Podoviridae and Siphoviridae) exhibited similar mass recovery as commonly used coliphage MS2 and were 7-fold better transported than known marine phage vB_PSPS-H40/1. Differing properties of the marine phages may be used to trace transport of indigenous viruses, natural colloids or anthropogenic nanomaterials and, hence, contribute to better risk analysis. Our results underpin the potential role of marine phages as microbial tracer for transport of colloidal particles and water flow.

AB - Oxygen limitation can be used as a simple environmental inducer for the expression of target genes. However, there is scarce information on the characteristics of microaerobic promoters potentially useful for cell engineering and synthetic biology applications. Here, we characterized the Vitreoscilla hemoglobin promoter (Pvgb) and a set of microaerobic endogenous promoters in Escherichia coli. Oxygen-limited cultures at different maximum oxygen transfer rates were carried out. The FMN-binding fluorescent protein (FbFP), which is a nonoxygen dependent marker protein, was used as a reporter. Fluorescence and fluorescence emission rates under oxygen-limited conditions were the highest when FbFP was under transcriptional control of PadhE, Ppfl and Pvgb. The lengths of the E. coli endogenous promoters were shortened by 60%, maintaining their key regulatory elements. This resulted in improved promoter activity in most cases, particularly for PadhE, Ppfl and PnarK. Selected promoters were also evaluated using an engineered E. coli strain expressing Vitreoscilla hemoglobin (VHb). The presence of the VHb resulted in a better repression using these promoters under aerobic conditions, and increased the specific growth and fluorescence emission rates under oxygen-limited conditions. These results are useful for the selection of promoters for specific applications and for the design of modified artificial promoters.

PMID- 27715022 TI - Including Bioconcentration Kinetics for the Prioritization and Interpretation of Regulatory Aquatic Toxicity Tests of Highly Hydrophobic Chemicals. AB - Worldwide, regulations of chemicals require short-term toxicity data for evaluating hazards and risks of the chemicals. Current data requirements on the registration of chemicals are primarily based on tonnage and do not yet consider properties of chemicals. For example, short-term ecotoxicity data are required for chemicals with production volume greater than 1 or 10 ton/y according to REACH, without considering chemical properties. Highly hydrophobic chemicals are characterized by low water solubility and slow bioconcentration kinetics, which may hamper the interpretation of short-term toxicity experiments. In this work, internal concentrations of highly hydrophobic chemicals were predicted for standard acute ecotoxicity tests at three trophic levels, algae, invertebrate, and fish. As demonstrated by comparison with maximum aqueous concentrations at water solubility, chemicals with an octanol-water partition coefficient (Kow) greater than 106 are not expected to reach sufficiently high internal concentrations for exerting effects within the test duration of acute tests with fish and invertebrates, even though they might be intrinsically toxic. This toxicity cutoff was explained by the slow uptake, i.e., by kinetics, not by thermodynamic limitations. Predictions were confirmed by data entries of the OECD's screening information data set (SIDS) (n = 746), apart from a few exceptions concerning mainly organometallic substances and those with inconsistency between water solubility and Kow. Taking error propagation and model assumptions into account, we thus propose a revision of data requirements for highly hydrophobic chemicals with log Kow > 7.4: Short-term toxicity tests can be limited to algae that generally have the highest uptake rate constants, whereas the primary focus of the assessment should be on persistence, bioaccumulation, and long-term effects.

AB - The salicylaldehyde-modified mesoporous silica (SA-MCM-41) was prepared through a co-condensation method. Through the bridge effect from the copper ion, which also acts as the nutrition of the plant, the model drug chlorpyrifos (CH) was supported on the copper(II) Schiff base mesoporous silica (Cu-MCM-41) to form a highly efficient sustained-release system (CH-Cu-MCM-41) for pesticide delivery. The experimental results showed that the larger the concentration of the copper ion, the more adsorption capacity (AC) of Cu-MCM-41 for chlorpyrifos and the smaller its release rate. The results confirmed the existence of a coordination bond between SA-MCM-41 and copper ions as well as a coordination bond between Cu MCM-41 and chlorpyrifos. The AC of SA-MCM-41 is 106 mg/g, while that of Cu-MCM-41 is 295 mg/g. The as-synthesized system showed significant pH sensitivity. Under the condition of pH <= 7, the release rate of chlorpyrifos decreased with increasing pH, whereas its release rate in weak base conditions was slightly larger than that in weak acid conditions. Meanwhile, the drug release rate of the as-synthesized system was also affected by the temperature. Their sustained release curves can be described by the Korsmeyer-Peppas equation.

AB - This paper demonstrates a facile hydrothermal method using ethylenediamine (EDA) as a "shape modifier" for the controlled synthesis of rod bunch, decanedron, spindle, flakiness, and flowerlike NaCaSiO3OH microarchitectures. The set of experimental conditions is important to obtain adjustable shape and size of NaCaSiO3OH particles, as the change in either the amount of EDA/H2O or reaction time, or the amount of NaOH. Accordingly, the crystal growth mechanism during the synthesis process is proposed, and it is found that the EDA, acting as the chelating agent and shape modifier, plays a crucial role in fine-tuning the NaCaSiO3OH morphology. Morphology evolution process of flowerlike NaCaSiO3OH as a function of NaOH is also explained in detail. Eu3+/Tb3+ doped NaCaSiO3OH samples exhibit strong red and green emission under ultraviolet excitation, corresponding to the characteristic electronic transitions of Eu3+ and Tb3+. These results imply that the morphology-tunable NaCaSiO3OH:Eu3+/Tb3+ microarchitectures with tunable luminescence properties are expected to have promising applications for micro/nano optical functional devices.

AB - Carbonyl sulfide (COS) is a gas that may play important roles in mammalian and bacterial biology, but its study is limited by a lack of suitable donor molecules. We report here the use of N-thiocarboxyanhydrides (NTAs) as COS donors that release the gas in a sustained manner under biologically relevant conditions with innocuous peptide byproducts. Carbonic anhydrase converts COS into H2S, allowing NTAs to serve as either COS or H2S donors, depending on the availability of the enzyme. Analysis of the pseudo-first-order H2S release rate under biologically relevant conditions revealed a release half-life of 75 min for the small molecule NTA under investigation. A polynorbornene bearing pendant NTAs made by ring-opening metathesis polymerization was also synthesized to generate a polymeric COS/H2S donor. A half-life of 280 min was measured for the polymeric donor. Endothelial cell proliferation studies revealed an enhanced rate of proliferation for cells treated with the NTA over untreated controls. PMID- 27715029 TI - Investigation of the Impact of Different Terms in the Second Order Hamiltonian on Excitation Energies of Valence and Rydberg States. AB - Describing electronically excited states of molecules accurately poses a challenging problem for theoretical methods. Popular second order techniques like Linear Response CC2 (CC2-LR), Partitioned Equation-of-Motion MBPT(2) (P-EOM MBPT(2)), or Equation-of-Motion CCSD(2) (EOM-CCSD(2)) often produce results that are controversial and are ill-balanced with their accuracy on valence and Rydberg type states. In this study, we connect the theory of these methods and, to investigate the origin of their different behavior, establish a series of intermediate variants. The accuracy of these on excitation energies of singlet valence and Rydberg electronic states is benchmarked on a large sample against high-accuracy Linear Response CC3 references. The results reveal the role of individual terms of the second order similarity transformed Hamiltonian, and the reason for the bad performance of CC2-LR in the description of Rydberg states. We also clarify the importance of the T1 transformation employed in the CC2 procedure, which is found to be very small for vertical excitation energies. PMID- 27715030 TI - Electrochemically and Photochemically Driven Ring Motions in a Disymmetrical Copper [2]-Catenate. AB - By applying the three-dimensional template effect of copper(I), previously used for making various interlocking ring systems, a new disymmetrical [2]-catenate has been made which consists of two different interlocking rings. One ring contains a 2,9-diphenyl-1,10-phenanthroline (dpp) unit whereas the other cycle incorporates both a dpp motif and a 2,2',6',2''-terpyridine (terpy) fragment, the coordination site of these two chelates pointing toward the inside of the ring. Depending on the oxidation state of the central metal (Cu(I) or Cu(II)), and thus on its preferred coordination number, two distinct situations have been observed. With monovalent copper, the two dpp units interact with the metal and the terpy fragment remains free, at the outside of the molecule. By contrast, when the catenate is complexed to divalent copper, the terpy motif is bonded to the metal and it is now a dpp ligand which lies at the periphery of the complex. This dual coordination mode leads to dramatically different molecular shapes and properties for both forms. The molecular motion which interconverts the four- and the five coordinate complexes can be triggered chemically, electrochemically, or photochemically by changing the oxidation state of the copper center (II/I). The process has been studied by electrochemistry and by UV-vis spectroscopy. Interestingly, once the stable 4-coordinate copper(I) complex has been oxidized to a thermodynamically unstable pseudo-tetrahedral copper(II) species, the rate of the gliding motion of the rings which will afford the stable 5-coordinate species (copper(II) coordinated to dpp and terpy) can be controlled at will. Under certain experimental conditions, the changeover process is extremely slow (weeks), and the 4-coordinate complex is more or less frozen. By contrast, addition of a coordinating counterion to the medium (Cl-) enormously speeds up the rearrangement and leads to the thermodynamically stable 5-coordinate complex within minutes. PMID- 27715031 TI - Synthesis and Isomeric Analysis of RuII Complexes Bearing Pentadentate Scaffolds. AB - A RuII-pentadentate polypyridyl complex [RuII(kappa-N5-bpy2PYMe)Cl]+ (1+, bpy2PYMe = 1-(2-pyridyl)-1,1-bis(6-2,2'-bipyridyl)ethane) and its aqua derivative [RuII(kappa-N5-bpy2PYMe)(H2O)]2+ (22+) were synthesized and characterized by experimental and computational methods. In MeOH, 1+ exists as two isomers in different proportions, cis (70%) and trans (30%), which are interconverted under thermal and photochemical conditions by a sequence of processes: chlorido decoordination, decoordination/recoordination of a pyridyl group, and chlorido recoordination. Under oxidative conditions in dichloromethane, trans-12+ generates a [RuIII(kappa-N4-bpy2PYMe)Cl2]+ intermediate after the exchange of a pyridyl ligand by a Cl- counterion, which explains the trans/cis isomerization observed when the system is taken back to Ru(II). On the contrary, cis-12+ is in direct equilibrium with trans-12+, with absence of the kappa-N4-bis-chlorido RuIII-intermediate. All these equilibria were modeled by density functional theory calculations. Interestingly, the aqua derivative is obtained as a pure trans-[RuII(kappa-N5-bpy2PYMe)(H2O)]2+ isomer (trans-22+), while the addition of a methyl substituent to a single bpy of the pentadentate ligand leads to the formation of a single cis isomer for both chlorido and aqua derivatives [RuII(kappa-N5-bpy(bpyMe)PYMe)Cl]+ (3+) and [RuII(kappa-N5 bpy(bpyMe)PYMe)(H2O)]2+ (42+) due to the steric constraints imposed by the modified ligand. This system was also structurally and electrochemically compared to the previously reported [RuII(PY5Me2)X]n+ system (X = Cl, n = 1 (5+); X = H2O, n = 2 (62+)), which also contains a kappa-N5-RuII coordination environment, and to the newly synthesized [RuII(PY4Im)X]n+ complexes (X = Cl, n = 1 (7+); X = H2O, n = 2 (82+)), which possess an electron-rich kappa-N4C-RuII site due to the replacement of a pyridyl group by an imidazolic carbene.

PMID- 27715032 TI - Encapsulation of Biological and Chemical Agents for Plant Nutrition and Protection: Chitosan/Alginate Microcapsules Loaded with Copper Cations and Trichoderma viride. AB - Novel chitosan/alginate microcapsules simultaneously loaded with copper cations and Trichoderma viride have been prepared and characterized. Information about the intermolecular interactions between biopolymers and bioactive agents was obtained by Fourier transform infrared spectroscopy. Encapsulation of T. viride spores and the presence of copper cations in the same compartment does not inhibit their activity. Microcapsule loading capacity and efficiency as well as swelling behavior and release depend on both the size of the microcapsule and bioactive agents. The in vitro copper cation release profile was fitted to a Korsmeyer-Peppas empirical model. Fickian diffusion was found to be a rate controlling mechanism of release from smaller microcapsules, whereas anomalous transport kinetics controlled release from larger microcapsules. The T. viride spore release profile exhibited exponential release over the initial lag time. The results obtained opened perspectives for the future use of chitosan/alginate microcapsules simultaneously loaded with biological and chemical agents in plant nutrition and protection. PMID- 27715034 TI - A Switchable Hybrid [2]-Catenane Based on Transition Metal Complexation and pi Electron Donor-Acceptor Interactions. AB - A bimodal [2]-catenane has been synthesized via a copper(I) templated synthesis. The compound contains both a transition metal coordination site and a set of pi electron rich and pi-electron deficient aromatic units suitable for the formation of acceptor-donor complexes. Each constituent ring is thus different from the other, and the organic backbone can adopt two favored contrasting orientations by circumrotation of one ring within the other: (i) in the metal complex mode, each dpp unit (dpp = 2,9-diphenyl-1,10-phenanthroline) is entwined about the other, while a cationic species is complexed in the coordination site thus created; (ii) in the organic pi-electron acceptor-donor complex mode, the dpp fragments are remote from one another, and the pi-electron rich and pi-electron deficient units stack to form a complex. The conversion of one binding mode to the other implies complete topographical rearrangement of the molecule. It can be triggered by adding or removing the cation center (Cu+, Li+, or H+), bonded to the dpp containing complexing site. Interestingly, this switching process can be easily monitored by 1H NMR, since it involves drastic relative orientational changes. It can also be evidenced by electronic spectroscopy. In particular, the proton driven rearrangement reactions lead to significant changes in the absorption spectrum, which correspond to the appearance (by deprotonation) and disappearance (by protonation of the dpp) of a charge transfer band (around 470 nm) resulting from the pi-electron donor-acceptor noncovalent interaction.

AB - Third-order nonlinear optical (NLO) properties of polymethine dyes have been widely studied for applications such as all-optical switching. However, the limited accuracy of the current computational methodologies has prevented a comprehensive understanding of the nature of the lowest excited states and their influence on the molecular optical and NLO properties. Here, attention is paid to the lowest excited-state energies and their energetic ratio, as these characteristics impact the figure-of-merit for all-optical switching. For a series of model polymethines, we compare several algebraic diagrammatic construction (ADC) schemes for the polarization propagator with approximate second-order coupled cluster (CC2) theory, the widely used INDO/MRDCI approach and the symmetry-adapted cluster configuration interaction (SAC-CI) algorithm incorporating singles and doubles linked excitation operators (SAC-CI SD-R). We focus in particular on the ground-to-excited state transition dipole moments and the corresponding state dipole moments, since these quantities are found to be of utmost importance for an effective description of the third-order polarizability gamma and two-photon absorption spectra. A sum-overstates expression has been used, which is found to quickly converge. While ADC(3/2) has been found to be the most appropriate method to calculate these properties, CC2 performs poorly.

AB - We propose and implement a highly efficient augmented surface hopping algorithm that (i) can be used for large simulations (with many nuclei and many electronic states) and (ii) includes the effects of decoherence without parametrization. Our protocol is based on three key modifications of the surface hopping methodology: (a) a novel separation of classical and quantum degrees of freedom that treats avoided and trivial crossings efficiently, (b) a multidimensional approximation of the time derivative matrix that avoids explicit construction of the derivative coupling at most time steps, and (c) an efficient approximation for the augmented fewest-switches surface hopping decoherence rate. We will show that this protocol can be several orders of magnitude more efficient than the traditional protocol for large multidimensional problems. Furthermore, the marginal cost for including decoherence effects is now negligible. PMID- 27715037 TI - Synthesis of biscopper(I) [3]-catenates: multiring interlocked coordinating systems.

AB - Detailed structural, magnetic, and photoluminescence characterization of a family of new compounds based on 5-cyanoisophthalate (CNip) ligand and several transition metal or lanthanide ions, namely, [Cu3(MU3-CNip)2(MU-H2O)2(MU3-OH)2]n (1), {[Co3(MU4-CNip)3(DMF)4].~2DMF}n (2), [Cd(MU4-CNip) (DMF)]n (3), {[Ln2(MU4 CNip)(MU3-CNip)2(DMF)4].~DMF.H2O}n (4-Ln) (with LnIII = Tb, Dy, and Er), {[Gd6(MU3-CNip)5(MU4-CNip)3(MU-form)2(H2O) (DMF)10].~3DMF.3H2O}n (5), {[Zn32(MU4 CNip)12(MU-CNip)12(MU4-O)8(H2O)24].~12DMF}n (6) (where DMF = dimethylformamide, form = formate), is reported. The large structural diversity found in the system may be explained mainly in terms of the coordination characteristics that are inherent to the employed metal ions, the coordination versatility of the dicarboxylic ligand and the synthetic conditions. Interestingly, some crystal structures (three-dimensional (3D) frameworks of 4-Ln and 5 and 3D network of 6) exhibit open architectures containing large solvent-occupied void systems, among which 5 reveals permanent porosity as confirmed by N2 adsorption measurements at 77 K. Magnetic direct current (dc) susceptibility data on compounds 1, 2, and 5 were measured. Moreover, compounds 2, 4-Dy, 4-Er, and 5 show slow magnetic relaxation, from which it is worth highlighting the effective energy barrier of 44 K at zero dc field for the dysprosium counterpart. Compound 5 also deserves to be mentioned given the few 3D Gd-organic frameworks reported examples. Photophysical properties were also accomplished at different temperatures, confirming both the fluorescent emission of 5-cyanoisophthalate ligands when coordinated to cadmium ions in 3 and their capacity to sensitize the long-lived fluorescence of the selected lanthanide ions in 4-Ln. Broken symmetry and time dependent density functional theory computational calculations support the experimental luminescence and magnetic properties.

AB - We herein reported the synthetic, structural, computational, and magnetic studies of four air-stable heptacoordinated mononuclear cobalt(II) complexes, namely, [CoII(tdmmb)(H2O)2][BF4]2 (1), [CoII(tdmmb)(CN)2].2H2O (2), [CoII(tdmmb)(NCS)2] (3), and [CoII(tdmmb)(SPh)2] (4) (tdmmb = 1,3,10,12-tetramethyl-1,2,11,12 tetraaza[[3](2,6)pyridino[3](2,9)-1,10-phenanthrolinophane-2,10-diene; SPh- = thiophenol anion). Constrained by the rigid pentadentate macrocyclic ligand tdmmb, the CoII centers in all of these complexes are in the heptacoordinated pentagonal-bipyramidal geometry. While the equatorial environments of these complexes remain very similar to each other, the axial ligands are systematically modified from C to N to O to S atoms. Analyses of the magnetic data and the ab initio calculations both reveal large easy-plane magnetic anisotropy (D > 0) for all four complexes. While the experimentally obtained D values do not show any clear tendency when the axial coordinated atoms change from C to N to O atoms (complexes 1-3), the largest value is for the heavier and softer S-atom coordinated complex 4. Because of significant magnetic anisotropy, all four complexes are field-induced single-ion magnets. This work represents a delicate modification of the magnetic anisotropy by tuning the chemical environment of the metal centers. PMID- 27715040 TI - Synthesis of Substituted 2,3-Benzodiazepines.

Isoquinolones 9 were obtained when an aldehyde group was used instead of a ketone. The key structures were confirmed by X-ray single-crystal diffraction analysis. PMID- 27715041 TI - Turn: Weak Interactions and Rotational Barriers in Molecules-Insights from Substituted Butynes. AB - The nature of the bonding and a definite preference for an eclipsed geometry in several substituted but-2-ynes, including certain novel derivatives are uncovered and examined. In particular, we consider the molecular species R3C-C=C-CR3 (where R= H, F, Cl, Br, I, and CN), their R3C-B=N-CR3 analogues, and a few novel exo bridge systems with intramolecular hydrogen bonds running parallel to the C-C=C-C chain. In some cases, the potential energy surfaces are remarkably flat-so flat, in fact, that free rotation is predicted for those molecules at very low temperatures. A systematic investigation of the bonding in the halogenated butynes demonstrates that the eclipsed conformation actually becomes more stable relative to the staggered form as R becomes larger and less electron-withdrawing. The rotational barriers (the differences in energy between the eclipsed and staggered geometries) are magnified significantly, however, in a special case where selected R groups at the ends of the R3C-C=C-CR'3 molecule form hydrogen bonds parallel to the C-C=C-C core. In those systems, the hydrogen bonds serve as a weak locking mechanism that favors the eclipsed conformation. A comparison of HF and uncorrected DFT methods versus the MP2(full), CCSD(T), and other dispersion-corrected methods confirms that correlation accounts to a significant extent for barriers in substituted butyne compounds. In the hydrogen-bonded systems, the barriers are comparable to and larger in some cases than the barriers observed for the more extensively studied ethane molecule.

AB - The structure of the dianion (SP,RC)-10 formed in the diastereoselective N,Cortho dilithiation of the phosphinimidic amide (RC)-Ph2P(?NCO2Me)NHCH(Me)Ph (5; dr of 95:5) with tert-butyllithium in THF has been elucidated using multinuclear magnetic resonance methods, including 2D 7Li,nX-HMQC (nX = 15N, 31P) correlations. (SP,RC)-10 consists of a monomer in which C,N and N,O chelation of the lithium cations generates a system containing a five- and a six-membered metallacycle, respectively, sharing a P-N bond with the lithium atoms connected through the NCO moiety of the phosphazenyl group. Selective deprotonation of the pro-S P-phenyl ring of 5 was ascertained through NOE measurements. DFT computations at the M06-2X(SMD,THF)/6-311+G(d,p)//M06-2X/6-31G(d) level showed that the stereoselective ortho deprotonation process fulfills the features of the CIPE model. The P?N linkage of the N-lithiated species (RC)-8 acts as a directing metalation group via N...LitBu coordination. The mixed complex that is formed evolves to a more stabilized species due to the intramolecular coordination of the OMe group to the lithium cation of the base. Abstraction of the ortho proton proceeds with energy barriers of 12.4 and 13.3 kcal/mol for the pro-R and pro-S phenyl rings. The preference for the latter is explained in terms of the Curtin Hammett principle.

AB - We present a detailed mechanistic study on the interaction and reaction of water monomer and water dimer with the smallest 3D aluminum particle (Al6) by employing density functional and explicitly correlated coupled cluster CCSD(T)-F12 theories. Water adsorption, dissociation, and dehydrogenation are considered. For the monomer reaction, where core-valence correlation and an extrapolation to the complete basis set limit is allowed for, our coupled cluster calculations predict the O-H dissociation barrier of about 2 kcal/mol. For the dimer reaction, two distinct reaction paths are identified, initiated by forming separate dimer complexes wherein (H2O)2 adsorbs mainly via the oxygen atom of the donor H2O molecule. The key O-H dissociation transition states of the dimer reaction involve a concerted migration of two H atoms resulting in the dissociation of the donor molecule and formation of the OH-water complex adsorbed on the metal cluster's surface. The most remarkable feature of both dimer reaction energy profiles is the lack of the overall energy barrier for the (rate-determining) O-H dissociation. The hydrogen bond acceptor molecule is suggested to have an extra catalytic effect on the O-H dissociation barrier of the hydrogen bond donor molecule by removing this barrier. A similar effect on the dehydrogenation step is indicated. PMID- 27715044 TI - The Activation of c-Src Tyrosine Kinase: Conformational Transition Pathway and Free Energy Landscape. AB - Tyrosine kinases are important cellular signaling allosteric enzymes that regulate cell growth, proliferation, metabolism, differentiation, and migration. Their activity must be tightly controlled, and malfunction can lead to a variety of diseases, particularly cancer. The nonreceptor tyrosine kinase c-Src, a prototypical model system and a representative member of the Src-family, functions as complex multidomain allosteric molecular switches comprising SH2 and SH3 domains modulating the activity of the catalytic domain. The broad picture of self-inhibition of c-Src via the SH2 and SH3 regulatory domains is well characterized from a structural point of view, but a detailed molecular mechanism understanding is nonetheless still lacking. Here, we use advanced computational methods based on all-atom molecular dynamics simulations with explicit solvent to advance our understanding of kinase activation. To elucidate the mechanism of regulation and self-inhibition, we have computed the pathway and the free energy landscapes for the "inactive-to-active" conformational transition of c-Src for different configurations of the SH2 and SH3 domains. Using the isolated c-Src catalytic domain as a baseline for comparison, it is observed that the SH2 and SH3 domains, depending upon their bound orientation, promote either the inactive or active state of the catalytic domain. The regulatory structural information from the SH2-SH3 tandem is allosterically transmitted via the N-terminal linker of the catalytic domain. Analysis of the conformational transition pathways also illustrates the importance of the conserved tryptophan 260 in activating c-Src, and reveals a series of concerted events during the activation process. PMID- 27715045 TI - Predicted Structures of the Proton-Bound Membrane-Embedded Rotor Rings of the Saccharomyces cerevisiae and Escherichia coli ATP Synthases. AB - Recent years have witnessed a renewed interest in the ATP synthase as a drug target against human pathogens. Indeed, clinical, biochemical, and structural data indicate that hydrophobic inhibitors targeting the membrane-embedded proton binding sites of the c-subunit ring could serve as last-resort antibiotics against multidrug resistant strains. However, because inhibition of the mitochondrial ATP synthase in humans is lethal, it is essential that these inhibitors be not only potent but also highly selective for the bacterial enzyme. To this end, a detailed understanding of the structure of this protein target is arguably instrumental. Here, we use computational methods to predict the atomic structures of the proton-binding sites in two prototypical c-rings: that of the ATP synthase from Saccharomyces cerevisiae, which is a model system for mitochondrial enzymes, and that from Escherichia coli, which can be pathogenic for humans. Our study reveals the structure of these binding sites loaded with protons and in the context of the membrane, that is, in the state that would mediate the recognition of a potential inhibitor. Both structures reflect a mode of proton coordination unlike those previously observed in other c-ring structures, whether experimental or modeled.

AB - A concise and novel method for site-selective alkylation of 1,3,6',3" tetraazidokanamycin has been developed that leads to the divergent synthesis of three classes of kanamycin A derivatives. These new amphiphilic kanamycin derivatives bearing alkyl chains length of 4, 6, 7, 8, 9, 10, 12, 14, and 16 have been tested for their antibacterial and antifungal activities. The antibacterial effect of the synthesized kanamycin derivatives declines or disappears as compared to the original kanamycin A. Several compounds, especially those with octyl chain at O-4" and/or O-6" positions on the ring III of kanamycin A, show very strong activity as antifungal agents. In addition, these compounds display no toxicity toward mammalian cells. Finally, computational calculation has revealed possible factors that are responsible for the observed regioselectivity. The simplicity in chemical synthesis and the fungal specific property make the lead compounds ideal candidates for the development of novel antifungal agents.

PMID- 27715049 TI - In-Vial Temperature Gradient Headspace Single Drop Microextraction Designed by Multiphysics Simulation. AB - Presented herein is a novel headspace single drop microextraction (HS-SDME) based on temperature gradient (TG) for an on-site preconcentration technique of volatile and semivolatile samples. First, an inner vial cap was designed as a cooling device for acceptor droplet in HS-SDME unit to achieve fast and efficient microextraction. Second, for the first time, an in-vial TG was generated between the donor phase in a sample vial at 80 degrees C and the acceptor droplet under the inner vial cap containing cooling liquid at -20 degrees C for a TG-HS-SDME. Third, a simple mathematic model and numerical simulations were developed by using heat transfer in fluids, Navier-Stokes and mass balance equations for conditional optimization, and dynamic illumination of the proposed extraction based on COMSOL Multiphysics. Five chlorophenols (CPs) were selected as model analytes to authenticate the proposed method. The comparisons revealed that the simulative results were in good agreement with the quantitative experiments, verifying the design of TG-HS-SDME via the numerical simulation. Under the optimum conditions, the extraction enrichments were improved from 302- to 388 fold within 2 min only, providing 3.5 to 4 times higher enrichment factors as compared to a typical HS-SDME. The simulation indicated that these improvements in the extraction kinetics could be attributed due to the applied temperature gap between the sample matrix and acceptor droplet within the small volume of headspace. Additionally, the experiments demonstrated a good linearity (0.03-100 MUg/L, R2 > 0.9986), low limit of detection (7-10 ng/L), and fair repeatability (<5.9% RSD, n = 6). All of the simulative and experimental results indicated the robustness, precision, and usefulness of TG-HS-SDME for trace analyses of analytes in a wide variety of environmental, pharmaceutical, food safety, and forensic samples.

PMID- 27715052 TI - Absolute pKas of Sulfonamides in Ionic Liquids: Comparisons to Molecular Solvents. AB - Absolute pKas of 25 sulfonamides in four ionic liquids (ILs) were measured spectroscopically with high precision and subsequently compared with those in conventional molecular solvents. It is found that the acidity order of these sulfonamides is as follows: in water > in DMSO > in ILs > in acetonitrile (ACN). The well-known solvent polarity index epsilon fails to explain the observed stronger bond-weakening effect of ILs in comparison to that of ACN, whose epsilon value is much greater. In addition, the regression analyses show that the pKas of sulfonamides determined in ILs linearly correlate with these in molecular solvents of distinct properties, but with various slopes. A rationale and related discussion on the effect of solvation in ILs are presented. PMID- 27715053 TI - Pesticide Chemical Research in Toxicology: Lessons from Nature. AB - Pesticide researchers are students of nature, and each new compound and mechanism turns a page in the ever-expanding encyclopedia of life. Pesticides are both probes to learn about life processes and tools for pest management to facilitate food production and enhance health. In contrast to some household and industrial chemicals, pesticides are assumed to be hazardous to health and the environment until proven otherwise. About a thousand current pesticides working by more than 100 different mechanisms have helped understand many processes and coupled events. Pesticide chemical research is a major source of toxicology information on new natural products, novel targets or modes of action, resistance mechanisms, xenobiotic metabolism, selective toxicity, safety evaluations, and recommendations for safe and effective pest management. Target binding site models help define the effect of substituent changes and predict modifications for enhanced potency and safety and circumvention of resistance. The contribution of pesticide chemical research in toxicology is illustrated here with two each of the newer or most important insecticides, herbicides, and fungicides. The insecticides are imidacloprid and chlorantraniliprole acting on the nicotinic acetylcholine receptor and the ryanodine receptor Ca2+ channel, respectively. The herbicides are glyphosate that inhibits aromatic amino acid biosynthesis and mesotrione that prevents plastoquinone and carotenoid formation. The fungicides are azoxystrobin inhibiting the Qo site of the cytochrome bc1 complex and prothioconazole inhibiting the 14alpha-demethylase in ergosterol biosynthesis. The two target sites involved for each type of pesticide account for 27-40% of worldwide sales for all insecticides, herbicides, and fungicides. In each case, selection for resistance involving a single amino acid change in the binding site or detoxifying enzyme circumvents the pesticide chemists's structure optimization and guarantees survival of the pest and a continuing job for the design chemist. These lessons from nature are a continuing part of pest management and maintaining human and environmental health.

AB - Hybrid metal-halide perovskites have potential as cost-effective gain media for laser technology because of their superior optoelectronic properties. Although lead-halide perovskites have been most widely studied to date, tin-based perovskites have been proposed as a less toxic alternative. In this Letter, we show that amplified spontaneous emission (ASE) in formamidinium tin triiodide (FASnI3) thin films is supported by an observed radiative monomolecular charge recombination pathway deriving from its unintentional doping. Such a radiative component will be active even at the lowest charge-carrier densities, opening a pathway for ultralow light-emission thresholds. Using time-resolved THz photoconductivity analysis, we further show that the material has an unprecedentedly high charge-carrier mobility of 22 cm2 V-1 s-1 favoring efficient transport. In addition, FASnI3 exhibits strong radiative bimolecular recombination and Auger rates that are over an order of magnitude lower than for lead-halide perovskites. In combination, these properties reveal that tin-halide perovskites are highly suited to light-emitting devices. PMID- 27715055 TI - General Mechanism of Osmolytes' Influence on Protein Stability Irrespective of the Type of Osmolyte Cosolvent. AB - The stability of proteins in an aqueous solution can be modified by the presence of osmolytes. The hydration sphere of stabilizing osmolytes is strikingly similar to the enhanced hydration sphere of a protein. This similarity leads to an increase in the protein stability. Moreover, the hydration sphere of destabilizing osmolytes is significantly different. These solutes generate in their surroundings so-called "structurally different water". The addition of such osmolytes causes "dissolution" of the specific protein hydration sphere and destabilizes its folded form. No relationship is seen between the stabilizing/destabilizing properties of osmolytes and their structure-making/ breaking influence on water. Furthermore, their accumulation at the protein surface or their exclusion does not determine the osmolytes' effect on protein stability. An explanation to the osmolytes' stabilizing/destabilizing influence originates in the similarity of water properties in osmolytes and protein solutions. The spectral infrared characteristic of water in an osmolyte solution allowed us to develop practical criteria for classifying solutes as stabilizing or destabilizing agents. PMID- 27715056 TI - Photogeneration and Mobility of Charge Carriers in Atomically Thin Colloidal InSe Nanosheets Probed by Ultrafast Terahertz Spectroscopy. AB - The implementation of next generation ultrathin electronics by applying highly promising dimensionality-dependent physical properties of two-dimensional (2D) semiconductors is ever increasing. In this context, the van der Waals layered semiconductor InSe has proven its potential as photodetecting material with high charge carrier mobility. We have determined the photogeneration charge carrier quantum yield and mobility in atomically thin colloidal InSe nanosheets (inorganic layer thickness 0.8 - 1.7 nm, mono-/double-layers, <=5 nm including ligands) by ultrafast transient terahertz (THz) spectroscopy. A near unity quantum yield of free charge carriers is determined for low photoexcitation density. The charge carrier quantum yield decreases at higher excitation density, due to recombination of electrons and holes, leading to the formation of neutral excitons. In the THz frequency domain we probe a charge mobility as high as 20 +/ 2 cm2/Vs. The THz mobility is similar to field-effect transistor mobilities extracted from unmodified exfoliated thin InSe devices. The current work provides the first results on charge carrier dynamics in ultrathin colloidal InSe nanosheets. PMID- 27715058 TI - Effect of Nitrogen Management on Structure and Physicochemical Properties of Rice Starch. AB - Nitrogen management (nitrogen application ratio in transplanting, tillering, and panicle initiation growth stages) is an important parameter in crop cultivation and is closely associated with rice yield and grain quality. The physicochemical and structural properties of starches separated from two rice varieties grown under four different nitrogen management ratios (0; 9:1; 7:3; 6:4) were investigated. As the percentage of fertilizer used in the panicle initiation stage increased, the content of small granules increased while the content of large granules decreased, the decreased amylose content resulting high selling power, water solubility, gelatinization enthalpy and low retrogradation. The crystallinity of the starch samples was found to be A-type. This study indicated that the best nitrogen management ratio for the cultivation of rice with the highest yield, desirable starch physicochemical properties for high quality cooked rice, and a moderate protein level was 7:3. PMID- 27715057 TI - Structure Determinants of Lagunamide A for Anticancer Activity and Its Molecular Mechanism of Mitochondrial Apoptosis. AB - Marine natural products are served as attractive source of anticancer therapeutics, with the great success of "first-in-class" drugs, such as Yondelis, Halaven, and Brentuximab vendotin. Lagunamides A-C from marine cyanobacterium, Lyngbya majuscula, exhibit exquisite growth inhibitory activities against cancer cells. In this study, we have systematically investigated the structure-activity relationships (SARs) of a concise collection of lagunamide A and its analogues constructed by total chemical synthesis against a broad panel of cancer cells derived from various tissues or organs, including A549, HeLa, U2OS, HepG2, BEL 7404, BGC-823, HCT116, MCF-7, HL-60, and A375. The R configuration of lagunamide A at C-39 position was found to be the structure determinant for anticancer activity. Further molecular mechanism study in A549 cells revealed that lagunamide A induced caspase-mediated mitochondrial apoptosis. Accompanied with the dissipation of mitochondrial membrane potential (Deltaphim) and overproduction of reactive oxygen species (ROS), lagunamide A led to mitochondrial dysfunction and finally caused cell death. Moreover, both anti- and pro-apoptotic B-cell lymphoma 2 (Bcl-2) family proteins participated in lagunamide A-induced mitochondrial apoptosis, especially myeloid cell leukemia-1 (Mcl-1). Overexpression of Mcl-1 partly rescued A549 cells from lagunamide A induced apoptosis. This study suggests that lagunamide A may exert anticancer property through mitochondrial apoptosis. Together, our findings would provide insightful information for the design of new anticancer drugs derived from lagunamides. PMID- 27715059 TI - Supramolecularly Assisted Modulation of Optical Properties of BODIPY Benzimidazole Conjugates. AB - Supramolecular host-guest interaction of neutral and cationic (protonated) forms of two boron-dipyromethane (BODIPY)-benzimidazole (mono- and di-benzimidazole) conjugate dyes with the macrocyclic host cucurbit[7]uril (CB7) has been investigated using photophysical and density functional theory studies. Expectedly, cationic forms of the dyes show exceptionally stronger binding than that of the neutral forms with CB7, which can be ascribed to the strong ion dipole interaction between the positive charge of the dye and the highly polarizable carbonyl portals of the host. The formation of dye-host inclusion complexes is supported by the significant changes in the photophysical properties and longer rotational relaxation times of the dye in the presence of CB7. Job's plot studies indicate the formation of a 1:1 inclusion complex for the mono and a 1:2 inclusion complex for the dibenzimidazole BODIPY dyes. Quantum chemical calculations are in good agreement with the inferences outlined from photophysical measurements. Findings from the studied dye-CB7 systems are of direct relevance to applications such as drug delivery, aqueous dye lasers, sensors, and so on. PMID- 27715060 TI - Controlled Generation of a p-n Junction in a Waveguide Integrated Graphene Photodetector. AB - With its electrically tunable light absorption and ultrafast photoresponse, graphene is a promising candidate for high-speed chip-integrated photonics. The generation mechanisms of photosignals in graphene photodetectors have been studied extensively in the past years. However, the knowledge about efficient light conversion at graphene p-n junctions has not yet been translated into high performance devices. Here, we present a graphene photodetector integrated on a silicon slot-waveguide, acting as a dual gate to create a p-n junction in the optical absorption region of the device. While at zero bias the photothermoelectric effect is the dominant conversion process, an additional photoconductive contribution is identified in a biased configuration. Extrinsic responsivities of 35 mA/W, or 3.5 V/W, at zero bias and 76 mA/W at 300 mV bias voltage are achieved. The device exhibits a 3 dB bandwidth of 65 GHz, which is the highest value reported for a graphene-based photodetector. PMID- 27715061 TI - The Template Determines Whether Chemically Identical Nanoparticle Scaffolds Show Elastic Recovery or Plastic Failure. AB - Subtle variations in the preparation of ice-templated nanoparticle assemblies yield monoliths that are chemically identical but exhibit qualitatively different mechanical behavior. We ice template aqueous dispersions to prepare macroporous monoliths largely comprising silica nanoparticles held together by a crosslinked polymer mesh. When the polymer is crosslinked in the presence of ice crystals, we obtain an elastic sponge that is capable of recovery after imposition of large compressive strains (up to 80%). If, however, the ice is lyophilized before the polymer is crosslinked, we obtain a plastic monolith that fails even for modest strains (less than 10%). The elastic sponge and the plastic monolith are chemically identical; they have the same organic content, the same ratio of polymer to crosslinker, and the same average crosslink density. Atomic force microscopy (AFM) was used to probe the local mechanical properties of the crosslinked polymer mesh. These measurements indicate that plastic monoliths dissipate significantly more energy and have a larger spatial variation in local mechanical response relative to the elastic sponges. We believe that this behavior might correlate with a wider spatial distribution of crosslinks in plastic scaffolds relative to elastic scaffolds.

PMID- 27715063 TI - "Staying Out" Rather than "Cracking In": Asymmetric Membrane Insertion of 12:0 Lysophosphocholine. AB - Interactions between detergents and model membranes are well described by the three-stage model: saturation and solubilization boundaries divide bilayer-only, bilayer-micelle coexistence, and micelle-only ranges. An underlying assumption of the model is the equilibration of detergent between the two membrane leaflets. However, many detergents partition asymmetrically at room temperature due to slow flip-flop, such as sodium dodecyl sulfate (SDS) and lysolipids. In this work, we use isothermal titration calorimetry (ITC) and dynamic light scattering (DLS) to investigate the solubilization of unilamellar POPC vesicles by 12:0 lysophosphocholine (12:0 LPC). Flip-flop of 12:0 LPC occurs beyond the time scale of our experiments, which establish a characteristic nonequilibrated state with asymmetric distribution: 12:0 LPC partitions primarily into the outer leaflet. Increasing asymmetry stress in the membrane does not lead to membrane failure, i.e., "cracking in" as seen for alkyl maltosides and other surfactants; instead, it reduces further membrane insertion which leads to the "staying out" of 12:0 LPC in solution. At above the critical micellar concentration of 12:0 LPC in the presence of the membrane, micelles persist and accommodate further LPC but take up lipid from vesicles only very slowly. Ultimately, solubilization proceeds via the micellar mechanism (Kragh-Hansen et al., 1995). With a combination of demicellization and solubilization experiments, we quantify the molar ratio partition coefficient (0.6 +/- 0.1 mM-1) and enthalpy of partitioning (6.1 +/- 0.3 kJ.mol-1) and estimate the maximum detergent/lipid ratio reached in the outer leaflet (<0.13). Despite the inapplicability of the three-stage model to 12:0 LPC at room temperature, we are able to extract quantitative information from ITC solubilization experiments and DLS that are important for the understanding of asymmetry-dependent processes such as endocytosis and the gating of mechanosensitive channels in vitro. PMID- 27715064 TI - A Pseudopolyrotaxane for Glucose-Responsive Insulin Release: The Effect of Binding Ability and Spatial Arrangement of Phenylboronic Acid Group. AB - A pseudopolyrotaxane (PPRX) comprising 3-carboxy-5-nitrophenylboronic acid modified gamma-cyclodextrin (NPBA-gamma-CyD) and naphthalene modified polyethylene glycol (Naph-PEG) as a sugar-responsive supramolecular structure is prepared. The binding of sugar by the NPBA group induced disintegration of the Naph-PEG/NPBA-gamma-CyD PPRX, allowing the components to be dissolved. The Naph PEG/NPBA-gamma-CyD PPRX exhibited better sensitivity compared to that of a PPRX based on 4-carboxyphenylboronic acid modified gamma-cyclodextrin (PBA-gamma-CyD). We have previously reported the unique structure of Naph-PEG/PBA-gamma-CyD PPRX, which formed an inclusion complex with a single-stranded PEG chain being threaded through the gamma-CyD rings, with the remaining internal space being occupied by the sugar-sensing PBA moiety from a neighboring ring, thus shielding it from sugar molecules and reducing the sugar sensitivity of the PPRX. In contrast, structural analyses in this study revealed that the sugar-sensing NPBA moiety in the Naph-PEG/NPBA-gamma-CyD PPRX is not included in the neighboring NPBA-gamma CyD. This spatial arrangement and the high affinity of NPBA for sugar contributed to the improved sugar responsivity. The enhanced NPBA-gamma-CyD was then applied to a PPRX containing Naph-PEG-appended insulin (Naph-PEG-Ins) that showed an improved response for glucose-induced insulin release.

AB - Antibody denaturation at surface-liquid interfaces plays an important role in the sensitivity of protein assays such as enzyme-linked immunosorbent assays (ELISAs). Surface immobilized antibodies must maintain their native state, with their antigen binding (Fab) region intact, to capture antigens from biological samples and permit disease detection. In this work, two identical sample sets were prepared with whole antibody IgG, F(ab')2 and Fc fragments, immobilized to either a silicon wafer, or a diethylene glycol dimethyl ether plasma polymer surface. Analysis was conducted on one sample set at Day 0, and the second sample set after 14 days in vacuum, with time-of-flight secondary-ion mass spectrometry (ToF-SIMS) for molecular species representative of denaturation. A 1003 mass fragment peak list was compiled from ToF-SIMS data and compared to a 35 amino acid mass fragment peak list using principal component analysis. Several ToF-SIMS secondary-ions, pertaining to disulfide and thiol species, were identified in the 14 day (presumably denatured) samples. A substrate and primary-ion independent marker for denaturation (ageing) was then produced using a ratio of mass peak intensities according to; Denaturation Ratio? [I_61.95+I_62.98+I_122.95+I_78.96+I_84.96+I_120.95 ]/[I_30.99+I_42.99+I_73.06+I_147.07+I_207.03 ] The ratio successfully identifies denaturation on both the silicon and plasma polymer substrates and for spectra generated with Mn+, Bi+, and Bi3+ primary ions. We believe this ratio could be employed to as a marker of denaturation of antibodies on a plethora of substrates.

AB - All-atom molecular dynamics (MD) simulations of the ionic liquid (IL) 1-hexyl-2,3 dimethylimidazolium bis(fluorosulfonyl)imide ([C6mmim][FSI]) and its binary mixtures with acetonitrile (ACN) have been reported for the first time. The presence of ACN as a cosolvent, similar to the effect of increasing temperature, causes enhancements in the ion translational motion and fluidity of the IL, leading to significant improvement of ionic conductivity and self-diffusion, which is well explained by a microscopic structural analysis. In neat IL and a concentrated IL mixture, self-diffusion of the cation is higher than that of the corresponding anion; however, further addition of ACN into the diluted mixtures with IL molar fractions (xIL's) below 0.50 results in more weakened interactions among the nearest ACN-anion neighbors compared to those among the ACN-cation neighbors so that the number of isolated anions is more than that of isolated cations under this condition, and the anions diffuse faster than the cations, as expected on the basis of their relative sizes. The velocity autocorrelation function analysis indicates an inverse relation between xIL and the mean collision time of each species. Additionally, at a fixed xIL, both the mean collision time and velocity randomization time of ACN are shorter than those of the ions. Gradual addition of ACN changes the morphology of nanosegregated domains and tends to disrupt ionic clusters (i.e., it scatters and decomposes both the polar and nonpolar domains) compared with pure IL, whereas both the radial and spatial distribution functions show the stabilization role of ACN in the close-contact ion-pair association. On the other hand, increasing ACN causes weakening of the structural correlations of the cation-cation and anion-anion neighbors in the solutions. ACN molecules appeared as a bridge, with balanced affinities between the polar and nonpolar domains, and no indication was observed for aggregation of ACN molecules in the studied mixtures that can rationalize good miscibility with imidazolium-based ILs. PMID- 27715067 TI - Molecular Scale Description of Anion Competition on Amine-Functionalized Surfaces. AB - Many industrial and biological processes involve the competitive adsorption of ions with different valencies and sizes at charged surfaces; heavy and precious metal ions are separated on the basis of their propensity to adsorb onto interfaces, often as anionic ion clusters (e.g., [MClx]n-). However, very little is known, both theoretically and experimentally, about the competition of factors that drive preferential adsorption, such as charge density or valence, at interfaces in technologically relevant systems. There are even contradictory pictures described by interfacial studies and real life applications, such as chlorometalate extractions, in which charge diffuse chlorometalate ions are extracted efficiently even though charge dense chloride ions present in the background are expected to occupy the interface. We studied the competition between divalent chlorometalate anions (PtCl62- and PdCl42-) and monovalent chloride anions on positively charged amine-functionalized surfaces using in situ specular X-ray reflectivity. Chloride anions were present in vast excess to simulate the conditions used in the commercial separation of heavy and precious metal ions. Our results suggest that divalent chlorometalate adsorption is a two step process and that the divalent anions preferentially adsorb at the interface despite having a charge/volume ratio lower than that of chloride. These results provide fundamental insight into the structural mechanisms that underpin transport in phases that are relevant to heavy and precious metal ion separations, explaining the high efficiency of low charge density ion transport processes in the presence of charge dense anions.

AB - An efficient and trans-diastereoselective Rh(I)-catalyzed 1,4-conjugate addition reaction of alkenylboronic acids and a homochiral (R)-4-silyloxycyclopentenone useful for the synthesis of derivatives of prostaglandins E and F is described for the first time. The reaction functions under mild conditions and is particularly rapid (<=6 h) under low power (50 W) microwave irradiation at 30 degrees C in MeOH in the presence of a catalytic amount of KOH. Under these conditions, 3 mol % of [RhCl(COD)]2 is typically required to produce high yields. The method also functions without microwave irradiation at 3 degrees C in the presence of a stoichiometric amount of KOH. Under these conditions, only 1.5 mol % of [RhCl(COD)]2 is needed, but the reaction is considerably slower. The method accepts a range of aryl- and alkyl-substituted alkenylboronic acids, and its utility has been demonstrated by the synthesis of PGF2alpha (dinoprost) and tafluprost.

PMID- 27715070 TI - [Clinically relevant possibilities and limits of differential diagnosis of megaloblastic anemia and myelodysplastic syndrome - refractory anemia type in bone marrow biopsies]. AB - INTRODUCTION: Megaloblastic anemia (MA) represents a subtype of macrocytic anemia caused by impaired DNA synthesis, mostly due to folate and vitamin B12 deficiency. Its mildest forms lead to macrocytosis without concomitant anemia, but more severe forms to thrombocytopenia and/or leucopenia as well. In majority of the cases, the diagnosis of MA dose not represent a serious clinical problem, however, other causes of macrocytosis including myelodysplastic syndrome (MDS) must be excluded. MATERIAL AND METHODS: In the period 2004-2015 we identified in our registry 126 consecutive bone marrow (BM) biopsies of patients with cytopenia/s in peripheral blood and suspicion either on MA or MDS of refractory anemia (RA) type. We performed a retrospective analysis of BM biopsies focused on evaluation of parameters useful for the differential diagnosis, as represented by (a) cellularity and proportions of BM precursors, (b) and their topography, (c) presence of maturation defects and dysplastic changes, (d) grade and extent of myelofibrosis, (e) iron deposits and (f) presence of "inflammatory" response in BM. Histological analyses were supported by immunohistochemical examinations. RESULTS: The series consisted of biopsies of 126 patients (61 men and 65 women) with average age 63 (14-88 years) - almost all patients (121/126) presented with anemia. Based on the findings we distinguished three diagnostic groups - MA (31 patients), MDS-RA (39) and bioptically unclasifiable case ("DIF DG" - 56 patients). Abnormalities of the BM cellularity were observed in 81 % and of topography in 73 % of all cases respectively. Megalobastic differentiation of erythropoesis was detected in 79 % and diagnostic dysplastic changes in 25 % of all biopsy cases. In 29 % of all biopsies ring sideroblasts were present, megakaryocytic nuclear lobulisation defects density changes were found in 61 % of all patients. In 14 % of all biopsies the BM myelofibrosis was absent, in contrast 5 % of the biopsies showed severe diffuse fibrosis. "Inflammatory" response was developed in 44 % of all biopsies. Iron deposits were absent in 26 %, decreased in 35 % and increased in 33 % of all the cases. CONCLUSIONS: From the point of view of histopathologist it seems to be difficult to distinguish BM hematopoietic changes in patients with MA and MDS-RA respectivelly, as histological examinations allowed determination of a definitive and correct diagnosis in about 55% of the cases. The crucial problem represents a decision whether the observed changes really result from the development of a clonal disease.Key words: megaloblastic anemia - megaloblastic differentiation - refractory anemia.

AB - Basal insulin has a clearly defined position in the recommendations for the treatment of patients with type 2 diabetes mellitus. General most common indication for administration is the addition in situation of the failure of noninsulin antidiabetic therapy or early insulin treatment of diabetes, as one of the second choice after metformin. In the recent years there is significant expansion of the range of antidiabetic drugs, including basal insulin analogues. In connection with the introduction of concentrated long-acting basal insulin analogues into the clinical practice many questions regarding clinical efficacy and safety raises especially comparing with the "classical" basal insulin analogues. Although it is very likely that in the current clinical practice these differences in a number of indications are of minimal impact, it is possible that in some situations clinically relevant differences can be found among the basal insulin analogues.Key words: basal insulin analogues - concentrated insulin - diabetes mellitus - EDITION trial - glargine - hypoglycemia - insulin therapy.

AB - Schnitzlers syndrome is an acquired auto-inflammatory disease of still unclear origin. The Strasbourg criteria were adopted (non-infectious fever, chronic urticaria, changes in the bone structure, leukocytosis and higher values of inflammatory markers - CRP and presence of monoclonal immunoglobulin mostly of type IgM, very rarely of IgG) to establish this diagnosis. The first-choice therapy for this disease is the blocking of interleukin-1 effects. In practice, the interleukin-1 receptor antagonist, anakinra, is the most commonly used. Currently reports also appear of the use of other medicines blocking the effect of interleukin-1, namely canakinumab and rilonacept. We have been treating 5 patients with anakinra (108, 72, 33, 32 and 1 months) on a long-term basis. In all the patients, we commenced administration of anakinra in a dose of 100 mg once a day. As a result of 100 mg being administered once a day, all symptoms went away completely in 4 patients, while they receded by about 75 % in 1 patient, without disappearing completely. This patient needs an increased dose of 2 ampoules per day on the days of spontaneously intensified medical ailments. After one year of treatment it turned out for one of the four patients whose symptoms had completely disappeared when administered the 100mg daily dose, that he only needed the respective dose of anakinra at 48-hour intervals. However this patient does not tolerate further extension of the intervals between dose administrations. We have not recorded any adverse effects of anakinra in the course of the treatment, and no decline in the efficiency of anakinra has been observed: it acts as effectively now as it did at the beginning of the treatment. The text discusses the differential diagnostics of the Schnitzler syndrome.Key words: anakinra - auto-inflammatory diseases - canakinumab - fever of unknown origin - FUO - interleukin 1 - cryopyrin-associated autoinflammatory syndrome (CAPS) - monoclonal gammopathy - rilonacept - Schnitzlers Syndrome - Adult Stills disease.

AB - Arrhythmogenic left ventricular cardiomyopathy (ALVC) is a rare condition characterised by progressive fibrofatty replacement of the myocardium of the left ventricle in combination with arrhythmias of left ventricular origin. ALVC has been linked to autosomal dominant mutations of genes encoding desmosomal proteins, similarly to the classic arrhythmogenic right ventricular cardiomyopathy with which it also shares pathological and prognostic features. It seems that isolated left or right ventricular abnormalities represent two extremes of the spectrum of clinical manifestations of a single disease: arrhythmogenic cardiomyopathy. In addition to arrhythmias originating from the left ventricle, the diagnosis of ALVC is based on identification of morphological changes of the left ventricle including late gadolinium enhancement with subepicardial to midwall distribution, corresponding to fibrous or fibrofatty replacement on histopathology. The diagnosis is confirmed by detection of a causal mutation. ALVC should be kept in mind in the differential diagnosis of ventricular tachycardia of non-ischemic origin.Key words: arrhythmogenic cardiomyopathy - cardiac magnetic resonance - late gadolinium enhancement - ventricular tachycardia.

AB - Until recently, vitamin K antagonists (VKA; predominantly warfarin) were the only oral anticoagulants for primary and secondary prevention of venous thromboembolism. Prevention and therapy with novel, direct, non-VKA oral anticoagulant agents (NOACs; DOACs: dabigatran, rivaroxaban, apixaban, edoxaban), have recently become available as an alternative to VKA. NOACs have been shown to be non-inferior or superior to VKA in clinical trials. Available results suggest that real world safety of NOACs is mostly consistent with results observed in clinical trials. The most effective method is triple simultaneous prevention of venous thromboembolism (pharmaco kinezio mechano phlebothromboemboloprophylaxis).Key words: oral anticoagulants - NOAC/DOAC - thromboprophylaxis - venous thromboembolism - VKA.

While the answer may seem as simple as the fact that nuclear forces are attractive, the full story is more complex and interesting. In this work we present numerical evidence from ab initio lattice simulations showing that nature is near a quantum phase transition, a zero temperature transition driven by quantum fluctuations. Using lattice effective field theory, we perform Monte Carlo simulations for systems with up to twenty nucleons. For even and equal numbers of protons and neutrons, we discover a first order transition at zero temperature from a Bose-condensed gas of alpha particles (^{4}He nuclei) to a nuclear liquid. Whether one has an alpha-particle gas or nuclear liquid is determined by the strength of the alpha-alpha interactions, and we show that the alpha-alpha interactions depend on the strength and locality of the nucleon-nucleon interactions. This insight should be useful in improving calculations of nuclear structure and important astrophysical reactions involving alpha capture on nuclei. Our findings also provide a tool to probe the structure of alpha cluster states such as the Hoyle state responsible for the production of carbon in red giant stars and point to a connection between nuclear states and the universal physics of bosons at large scattering length. PMID- 27715078 TI - Noise-Resilient Quantum Computing with a Nitrogen-Vacancy Center and Nuclear Spins. AB - Selective control of qubits in a quantum register for the purposes of quantum information processing represents a critical challenge for dense spin ensembles in solid-state systems. Here we present a protocol that achieves a complete set of selective electron-nuclear gates and single nuclear rotations in such an ensemble in diamond facilitated by a nearby nitrogen-vacancy (NV) center. The protocol suppresses internuclear interactions as well as unwanted coupling between the NV center and other spins of the ensemble to achieve quantum gate fidelities well exceeding 99%. Notably, our method can be applied to weakly coupled, distant spins representing a scalable procedure that exploits the exceptional properties of nuclear spins in diamond as robust quantum memories. PMID- 27715079 TI - Interfacial Free Energy as the Key to the Pressure-Induced Deceleration of Ice Nucleation. AB - The avoidance of water freezing is the holy grail in the cryopreservation of biological samples, food, and organs. Fast cooling rates are used to beat ice nucleation and avoid cell damage. This strategy can be enhanced by applying high pressures to decrease the nucleation rate, but the physics behind this procedure has not been fully understood yet. We perform computer experiments to investigate ice nucleation at high pressures consisting in embedding ice seeds in supercooled water. We find that the slowing down of the nucleation rate is mainly due to an increase of the ice I-water interfacial free energy with pressure. Our work also clarifies the molecular mechanism of ice nucleation for a wide pressure range. This study is not only relevant to cryopreservation, but also to water amorphization and climate change modeling. PMID- 27715080 TI - Theory of Acoustic Raman Modes in Proteins. AB - We present a theoretical analysis that associates the resonances of extraordinary acoustic Raman (EAR) spectroscopy [Wheaton et al., Nat. Photonics 9, 68 (2015)] with the collective modes of proteins. The theory uses the anisotropic elastic network model to find the protein acoustic modes, and calculates Raman intensity by treating the protein as a polarizable ellipsoid. Reasonable agreement is found between EAR spectra and our theory. Protein acoustic modes have been extensively studied theoretically to assess the role they play in protein function; this result suggests EAR spectroscopy as a new experimental tool for studies of protein acoustic modes. PMID- 27715081 TI - Self-Induced Glassiness and Pattern Formation in Spin Systems Subject to Long Range Interactions. AB - We study the glass formation in two- and three-dimensional Ising and Heisenberg spin systems subject to competing interactions and uniaxial anisotropy with a mean-field approach. In three dimensions, for sufficiently strong anisotropy the systems always modulate in a striped phase. Below a critical strength of the anisotropy, a glassy phase exists in a finite range of temperature, and it becomes more stable as the system becomes more isotropic. In two dimensions the criticality is always avoided and the glassy phase always exists. PMID- 27715082 TI - Exact Bethe Ansatz Spectrum of a Tight-Binding Chain with Dephasing Noise. AB - We construct an exact map between a tight-binding model on any bipartite lattice in the presence of dephasing noise and a Hubbard model with imaginary interaction strength. In one dimension, the exact many-body Liouvillian spectrum can be obtained by application of the Bethe ansatz method. We find that both the nonequilibrium steady state and the leading decay modes describing the relaxation at late times are related to the eta-pairing symmetry of the Hubbard model. We show that there is a remarkable relation between the time evolution of an arbitrary k-point correlation function in the dissipative system and k-particle states of the corresponding Hubbard model.

AB - We present the first experimental realization of coherent Bragg scattering off a one-dimensional system-two strings of atoms strongly coupled to a single photonic mode-realized by trapping atoms in the evanescent field of a tapered optical fiber, which also guides the probe light. We report nearly 12% power reflection from strings containing only about 1000 cesium atoms, an enhancement of 2 orders of magnitude compared to reflection from randomly positioned atoms. This result paves the road towards collective strong coupling in 1D atom-photon systems. Our approach also allows for a straightforward fiber connection between several distant 1D atomic crystals. PMID- 27715085 TI - Global Optimization, Local Adaptation, and the Role of Growth in Distribution Networks. AB - Highly optimized complex transport networks serve crucial functions in many man made and natural systems such as power grids and plant or animal vasculature. Often, the relevant optimization functional is nonconvex and characterized by many local extrema. In general, finding the global, or nearly global optimum is difficult. In biological systems, it is believed that such an optimal state is slowly achieved through natural selection. However, general coarse grained models for flow networks with local positive feedback rules for the vessel conductivity typically get trapped in low efficiency, local minima. In this work we show how the growth of the underlying tissue, coupled to the dynamical equations for network development, can drive the system to a dramatically improved optimal state. This general model provides a surprisingly simple explanation for the appearance of highly optimized transport networks in biology such as leaf and animal vasculature. PMID- 27715086 TI - Controlling Nonsequential Double Ionization in Two-Color Circularly Polarized Femtosecond Laser Fields. AB - Atoms undergoing strong-field ionization in two-color circularly polarized femtosecond laser fields exhibit unique two-dimensional photoelectron trajectories and can emit bright circularly polarized extreme ultraviolet and soft-x-ray beams. In this Letter, we present the first experimental observation of nonsequential double ionization in these tailored laser fields. Moreover, we can enhance or suppress nonsequential double ionization by changing the intensity ratio and helicity of the two driving laser fields to maximize or minimize high energy electron-ion rescattering. Our experimental results are explained through classical simulations, which also provide insight into how to optimize the generation of circularly polarized high harmonic beams. PMID- 27715087 TI - Deformation Behavior across the Zircon-Scheelite Phase Transition. AB - The pressure effects on plastic deformation and phase transformation mechanisms of materials are of great importance to both Earth science and technological applications. Zircon-type materials are abundant in both nature and the industrial field; however, there is still no in situ study of their deformation behavior. Here, by employing radial x-ray diffraction in a diamond anvil cell, we investigate the dislocation-induced texture evolution of zircon-type gadolinium vanadate (GdVO_{4}) in situ under pressure and across its phase transitions to its high-pressure polymorphs. Zircon-type GdVO_{4} develops a (001) compression texture associated with dominant slip along ?100?{001} starting from 5 GPa. This (001) texture transforms into a (110) texture during the zircon-scheelite phase transition. Our observation demonstrates a martensitic mechanism for the zircon scheelite transformation. This work will help us understand the local deformation history in the upper mantle and transition zone and provides fundamental guidance on material design and processing for zircon-type materials. PMID- 27715088 TI - How Isotropic is the Universe? AB - A fundamental assumption in the standard model of cosmology is that the Universe is isotropic on large scales. Breaking this assumption leads to a set of solutions to Einstein's field equations, known as Bianchi cosmologies, only a subset of which have ever been tested against data. For the first time, we consider all degrees of freedom in these solutions to conduct a general test of isotropy using cosmic microwave background temperature and polarization data from Planck. For the vector mode (associated with vorticity), we obtain a limit on the anisotropic expansion of (sigma_{V}/H)_{0}<4.7*10^{-11} (95% C.L.), which is an order of magnitude tighter than previous Planck results that used cosmic microwave background temperature only. We also place upper limits on other modes of anisotropic expansion, with the weakest limit arising from the regular tensor mode, (sigma_{T,reg}/H)_{0}<1.0*10^{-6} (95% C.L.). Including all degrees of freedom simultaneously for the first time, anisotropic expansion of the Universe is strongly disfavored, with odds of 121 000:1 against. PMID- 27715089 TI - Towards Efficient Orbital-Dependent Density Functionals for Weak and Strong Correlation. AB - We present a new paradigm for the design of exchange-correlation functionals in density-functional theory. Electron pairs are correlated explicitly by means of the recently developed second order Bethe-Goldstone equation (BGE2) approach. Here we propose a screened BGE2 (sBGE2) variant that efficiently regulates the coupling of a given electron pair. sBGE2 correctly dissociates H_{2} and H_{2}^{+}, a problem that has been regarded as a great challenge in density functional theory for a long time. The sBGE2 functional is then taken as a building block for an orbital-dependent functional, termed ZRPS, which is a natural extension of the PBE0 hybrid functional. While worsening the good performance of sBGE2 in H_{2} and H_{2}^{+}, ZRPS yields a remarkable and consistent improvement over other density functionals across various chemical environments from weak to strong correlation. PMID- 27715090 TI - Initial Atomic Motion Immediately Following Femtosecond-Laser Excitation in Phase Change Materials. AB - Despite the fact that phase-change materials are widely used for data storage, no consensus exists on the unique mechanism of their ultrafast phase change and its accompanied large and rapid optical change. By using the pump-probe observation method combining a femtosecond optical laser and an x-ray free-electron laser, we substantiate experimentally that, in both GeTe and Ge_{2}Sb_{2}Te_{5} crystals, rattling motion of mainly Ge atoms takes place with keeping the off-center position just after femtosecond-optical-laser irradiation, which eventually leads to a higher symmetry or disordered state. This very initial rattling motion in the undistorted lattice can be related to instantaneous optical change due to the loss of resonant bonding that characterizes GeTe-based phase change materials. Based on the amorphous structure derived by first-principles molecular dynamics simulation, we infer a plausible ultrafast amorphization mechanism via nonmelting. PMID- 27715091 TI - Triple-Resonant Brillouin Light Scattering in Magneto-Optical Cavities. AB - An enhancement in Brillouin light scattering of optical photons with magnons is demonstrated in magneto-optical whispering gallery mode resonators tuned to a triple-resonance point. This occurs when both the input and output optical modes are resonant with those of the whispering gallery resonator, with a separation given by the ferromagnetic resonance frequency. The identification and excitation of specific optical modes allows us to gain a clear understanding of the mode matching conditions. A selection rule due to wave vector matching leads to an intrinsic single-sideband excitation. Strong suppression of one sideband is essential for one-to-one frequency mapping in coherent optical-to-microwave conversion. PMID- 27715092 TI - Pointlike Inclusion Interactions in Tubular Membranes. AB - Membrane tubes and tubular networks are ubiquitous in living cells. Inclusions like proteins are vital for both the stability and the dynamics of such networks. These inclusions interact via the curvature deformations they impose on the membrane. We analytically study the resulting membrane mediated interactions in strongly curved tubular membranes. We model inclusions as constraints coupled to the curvature tensor of the membrane tube. First, as special test cases, we analyze the interaction between ring- and rod-shaped inclusions. Using Monte Carlo simulations, we further show how pointlike inclusions interact to form linear aggregates. To minimize the curvature energy of the membrane, inclusions self-assemble into either line- or ringlike patterns. Our results show that the global curvature of the membrane strongly affects the interactions between proteins embedded in it, and can lead to the spontaneous formation of biologically relevant structures. PMID- 27715093 TI - Nonsequential Double Ionization by Counterrotating Circularly Polarized Two-Color Laser Fields. AB - We report on nonsequential double ionization of Ar by a laser pulse consisting of two counterrotating circularly polarized fields (390 and 780 nm). The double ionization probability depends strongly on the relative intensity of the two fields and shows a kneelike structure as a function of intensity. We conclude that double ionization is driven by a beam of nearly monoenergetic recolliding electrons, which can be controlled in intensity and energy by the field parameters. The electron momentum distributions show the recolliding electron as well as a second electron which escapes from an intermediate excited state of Ar^{+}. PMID- 27715094 TI - Signatures of Quantum Coherences in Rydberg Excitons. AB - Coherent optical control of individual particles has been demonstrated both for atoms and semiconductor quantum dots. Here we demonstrate the emergence of quantum coherent effects in semiconductor Rydberg excitons in bulk Cu_{2}O. Because of the spectral proximity between two adjacent Rydberg exciton states, a single-frequency laser may pump both resonances with little dissipation from the detuning. As a consequence, additional resonances appear in the absorption spectrum that correspond to dressed states consisting of two Rydberg exciton levels coupled to the excitonic vacuum, forming a V-type three-level system, but driven only by one laser light source. We show that the level of pure dephasing in this system is extremely low. These observations are a crucial step towards coherently controlled quantum technologies in a bulk semiconductor. PMID- 27715095 TI - Evidence of Toroidally Localized Turbulence with Applied 3D Fields in the DIII-D Tokamak. AB - New evidence indicates that there is significant 3D variation in density fluctuations near the boundary of weakly 3D tokamak plasmas when resonant magnetic perturbations are applied to suppress transient edge instabilities. The increase in fluctuations is concomitant with an increase in the measured density gradient, suggesting that this toroidally localized gradient increase could be a mechanism for turbulence destabilization in localized flux tubes. Two-fluid magnetohydrodynamic simulations find that, although changes to the magnetic field topology are small, there is a significant 3D variation of the density gradient within the flux surfaces that is extended along field lines. This modeling agrees qualitatively with the measurements. The observed gradient and fluctuation asymmetries are proposed as a mechanism by which global profile gradients in the pedestal could be relaxed due to a local change in the 3D equilibrium. These processes may play an important role in pedestal and scrape-off layer transport in ITER and other future tokamak devices with small applied 3D fields. PMID- 27715096 TI - Stress Singularities in Swelling Soft Solids. AB - When a swelling soft solid is rigidly constrained on all sides except for a circular opening, it will bulge out to expand as observed during decompressive craniectomy, a surgical procedure used to reduce stresses in swollen brains. While the elastic energy of the solid decreases throughout this process, large stresses develop close to the opening. At the point of contact, the stresses exhibit a singularity similar to the ones found in the classic punch indentation problem. Here, we study the stresses generated by swelling and the evolution of the bulging shape associated with this process. We also consider the possibility of damage triggered by zones of either high shear stresses or high fiber stretches. PMID- 27715097 TI - Improved Error Thresholds for Measurement-Free Error Correction. AB - Motivated by limitations and capabilities of neutral atom qubits, we examine whether measurement-free error correction can produce practical error thresholds. We show that this can be achieved by extracting redundant syndrome information, giving our procedure extra fault tolerance and eliminating the need for ancilla verification. The procedure is particularly favorable when multiqubit gates are available for the correction step. Simulations of the bit-flip, Bacon-Shor, and Steane codes indicate that coherent error correction can produce threshold error rates that are on the order of 10^{-3} to 10^{-4}-comparable with or better than measurement-based values, and much better than previous results for other coherent error correction schemes. This indicates that coherent error correction is worthy of serious consideration for achieving protected logical qubits. PMID- 27715098 TI - Machine Learning Energies of 2 Million Elpasolite (ABC_{2}D_{6}) Crystals. AB - Elpasolite is the predominant quaternary crystal structure (AlNaK_{2}F_{6} prototype) reported in the Inorganic Crystal Structure Database. We develop a machine learning model to calculate density functional theory quality formation energies of all ~2*10^{6} pristine ABC_{2}D_{6} elpasolite crystals that can be made up from main-group elements (up to bismuth). Our model's accuracy can be improved systematically, reaching a mean absolute error of 0.1 eV/atom for a training set consisting of 10*10^{3} crystals. Important bonding trends are revealed: fluoride is best suited to fit the coordination of the D site, which lowers the formation energy whereas the opposite is found for carbon. The bonding contribution of the elements A and B is very small on average. Low formation energies result from A and B being late elements from group II, C being a late (group I) element, and D being fluoride. Out of 2*10^{6} crystals, 90 unique structures are predicted to be on the convex hull-among which is NFAl_{2}Ca_{6}, with a peculiar stoichiometry and a negative atomic oxidation state for Al. PMID- 27715099 TI - Quantum-Enhanced Machine Learning. AB - The emerging field of quantum machine learning has the potential to substantially aid in the problems and scope of artificial intelligence. This is only enhanced by recent successes in the field of classical machine learning. In this work we propose an approach for the systematic treatment of machine learning, from the perspective of quantum information. Our approach is general and covers all three main branches of machine learning: supervised, unsupervised, and reinforcement learning. While quantum improvements in supervised and unsupervised learning have been reported, reinforcement learning has received much less attention. Within our approach, we tackle the problem of quantum enhancements in reinforcement learning as well, and propose a systematic scheme for providing improvements. As an example, we show that quadratic improvements in learning efficiency, and exponential improvements in performance over limited time periods, can be obtained for a broad class of learning problems. PMID- 27715100 TI - Correlation-Enhanced Odd-Parity Interorbital Singlet Pairing in the Iron-Pnictide Superconductor LiFeAs. AB - The rich variety of iron-based superconductors and their complex electronic structure lead to a wide range of possibilities for gap symmetry and pairing components. Here we solve in the two-Fe Brillouin zone the full frequency dependent linearized Eliashberg equations to investigate spin-fluctuations mediated Cooper pairing for LiFeAs. The magnetic excitations are calculated with the random phase approximation on a correlated electronic structure obtained with density functional theory and dynamical mean field theory. The interaction between electrons through Hund's coupling promotes both the intraorbital d_{xz(yz)} and the interorbital magnetic susceptibility. As a consequence, the leading pairing channel, conventional s^{+-}, acquires sizable interorbital d_{xy}-d_{xz(yz)} singlet pairing with odd parity under glide-plane symmetry. The combination of intra- and interorbital components makes the results consistent with available experiments on the angular dependence of the gaps observed on the different Fermi surfaces. PMID- 27715101 TI - Thermodynamics versus Local Density Fluctuations in the Metal-Mott-Insulator Crossover. AB - The crossover between a metal and a Mott insulator leads to a localization of fermions from delocalized Bloch states to localized states. We experimentally study this crossover using fermionic atoms in an optical lattice by measuring thermodynamic and local (on-site) density correlations. In the metallic phase at incommensurable filling we observe the violation of the local fluctuation dissipation theorem indicating that the thermodynamics of the system cannot be characterized by local observables alone. In contrast, in the Mott insulator we observe the convergence of local and thermodynamic fluctuations indicating the absence of long-range density-density correlations. PMID- 27715102 TI - Double-Core-Hole States in Neon: Lifetime, Post-Collision Interaction, and Spectral Assignment. AB - Using synchrotron radiation and high-resolution electron spectroscopy, we have directly observed and identified specific photoelectrons from K^{-2}V states in neon corresponding to simultaneous 1s ionization and 1s->valence excitation. The natural lifetime broadening of the K^{-2}V states and the relative intensities of different types of shakeup channels have been determined experimentally and compared to ab initio calculations. Moreover, the high-energy Auger spectrum resulting from the decay of Ne^{2+}K^{-2} and Ne^{+}K^{-2}V states as well as from participator Auger decay from Ne^{+}K^{-1}L^{-1}V states, has been measured and assigned in detail utilizing the characteristic differences in lifetime broadenings of these core hole states. Furthermore, post collision interaction broadening of Auger peaks is clearly observed only in the hypersatellite spectrum from K^{-2} states, due to the energy sharing between the two 1s photoelectrons which favors the emission of one slow and one fast electron. PMID- 27715103 TI - Z_{2} and Chiral Anomalies in Topological Dirac Semimetals. AB - We demonstrate that topological Dirac semimetals, which possess two Dirac nodes, separated in momentum space along a rotation axis and protected by rotational symmetry, exhibit an additional quantum anomaly, distinct from the chiral anomaly. This anomaly, which we call the Z_{2} anomaly, is a consequence of the fact that the Dirac nodes in topological Dirac semimetals carry a Z_{2} topological charge. The Z_{2} anomaly refers to nonconservation of this charge in the presence of external fields due to quantum effects and has observable consequences due to its interplay with the chiral anomaly. We discuss possible implications of this for the interpretation of magnetotransport experiments on topological Dirac semimetals. We also provide a possible explanation for the magnetic field dependent angular narrowing of the negative longitudinal magnetoresistance, observed in a recent experiment on Na_{3}Bi. PMID- 27715104 TI - Necessary Condition for Emergent Symmetry from the Conformal Bootstrap. AB - We use the conformal bootstrap program to derive the necessary conditions for emergent symmetry enhancement from discrete symmetry (e.g., Z_{n}) to continuous symmetry [e.g., U(1)] under the renormalization group flow. In three dimensions, in order for Z_{2} symmetry to be enhanced to U(1) symmetry, the conformal bootstrap program predicts that the scaling dimension of the order parameter field at the infrared conformal fixed point must satisfy Delta_{1}>1.08. We also obtain the similar necessary conditions for Z_{3} symmetry with Delta_{1}>0.580 and Z_{4} symmetry with Delta_{1}>0.504 from the simultaneous conformal bootstrap analysis of multiple four-point functions. As applications, we show that our necessary conditions impose severe constraints on the nature of the chiral phase transition in QCD, the deconfinement criticality in Neel valence bond solid transitions, and anisotropic deformations in critical O(n) models. We prove that some fixed points proposed in the literature are unstable under the perturbation that cannot be forbidden by the discrete symmetry. In these situations, the second-order phase transition with enhanced symmetry cannot happen. PMID- 27715105 TI - Thermodynamics of Accelerating Black Holes. AB - We address a long-standing problem of describing the thermodynamics of an accelerating black hole. We derive a standard first law of black hole thermodynamics, with the usual identification of entropy proportional to the area of the event horizon-even though the event horizon contains a conical singularity. This result not only extends the applicability of black hole thermodynamics to realms previously not anticipated, it also opens a possibility for studying novel properties of an important class of exact radiative solutions of Einstein equations describing accelerated objects. We discuss the thermodynamic volume, stability, and phase structure of these black holes. PMID- 27715106 TI - Ultrafast Spin Density Wave Transition in Chromium Governed by Thermalized Electron Gas. AB - The energy and momentum selectivity of time- and angle-resolved photoemission spectroscopy is exploited to address the ultrafast dynamics of the antiferromagnetic spin density wave (SDW) transition photoexcited in epitaxial thin films of chromium. We are able to quantitatively extract the evolution of the SDW order parameter Delta through the ultrafast phase transition and show that Delta is governed by the transient temperature of the thermalized electron gas, in a mean field description. The complete destruction of SDW order on a sub 100 fs time scale is observed, much faster than for conventional charge density wave materials. Our results reveal that equilibrium concepts for phase transitions such as the order parameter may be utilized even in the strongly nonadiabatic regime of ultrafast photoexcitation. PMID- 27715107 TI - Fate of Spinons at the Mott Point. AB - Gapless spin liquids have recently been observed in several frustrated Mott insulators, with elementary spin excitations-"spinons"-reminiscent of degenerate Fermi systems. However, their precise role at the Mott point, where charge fluctuations begin to proliferate, remains controversial and ill understood. Here we present the simplest theoretical framework that treats the dynamics of emergent spin and charge excitations on the same footing, providing a new physical picture of the Mott metal-to-insulator transition at half filing. We identify a generic orthogonality mechanism leading to strong damping of spinons, arising as soon as the Mott gap closes. Our results indicate that spinons should not play a significant role within the high-temperature quantum critical regime above the Mott point-in striking agreement with all available experiments.

AB - This corrects the article DOI: 10.1103/PhysRevLett.117.116601. PMID- 27715111 TI - Shocks in the Early Universe. AB - We point out a surprising consequence of the usually assumed initial conditions for cosmological perturbations. Namely, a spectrum of Gaussian, linear, adiabatic, scalar, growing mode perturbations not only creates acoustic oscillations of the kind observed on very large scales today, it also leads to the production of shocks in the radiation fluid of the very early Universe. Shocks cause departures from local thermal equilibrium as well as create vorticity and gravitational waves. For a scale-invariant spectrum and standard model physics, shocks form for temperatures 1 GeV2gamma and eta->3pi^{0}. The results show that the narrow structure previously observed in eta photoproduction from the neutron is only apparent in sigma_{1/2} and hence, most likely related to a spin-1/2 amplitude. Nucleon resonances that contribute to this partial wave in eta production are only N 1/2^{-} (S_{11}) and N 1/2^{+} (P_{11}). Furthermore, the extracted Legendre coefficients of the angular distributions for sigma_{1/2} are in good agreement with recent reaction model predictions assuming a narrow resonance in the P_{11} wave as the origin of this structure. PMID- 27715119 TI - Spatiotemporal Wave Front Shaping in a Microwave Cavity. AB - Controlling waves in complex media has become a major topic of interest, notably through the concepts of time reversal and wave front shaping. Recently, it was shown that spatial light modulators can counterintuitively focus waves both in space and time through multiple scattering media when illuminated with optical pulses. In this Letter, we transpose the concept to a microwave cavity using flat arrays of electronically tunable resonators. We prove that maximizing the Green's function between two antennas at a chosen time yields diffraction limited spatiotemporal focusing. Then, changing the photons' dwell time inside the cavity, we modify the relative distribution of the spatial and temporal degrees of freedom (DOF), and we demonstrate that it has no impact on the field enhancement: wave front shaping makes use of all available DOF, irrespective of their spatial or temporal nature. Our results prove that wave front shaping using simple electronically reconfigurable arrays of reflectors is a viable approach to the spatiotemporal control of microwaves, with potential applications in medical imaging, therapy, telecommunications, radar, or sensing. They also offer new fundamental insights regarding the coupling of spatial and temporal DOF in complex media. PMID- 27715120 TI - Comment on "Cortical Flow-Driven Shapes of Nonadherent Cells". PMID- 27715121 TI - Large Bragg Reflection from One-Dimensional Chains of Trapped Atoms Near a Nanoscale Waveguide. AB - We report experimental observations of a large Bragg reflection from arrays of cold atoms trapped near a one-dimensional nanoscale waveguide. By using an optical lattice in the evanescent field surrounding a nanofiber with a period nearly commensurate with the resonant wavelength, we observe a reflectance of up to 75% for the guided mode. Each atom behaves as a partially reflecting mirror and an ordered chain of about 2000 atoms is sufficient to realize an efficient Bragg mirror. Measurements of the reflection spectra as a function of the lattice period and the probe polarization are reported. The latter shows the effect of the chiral character of nanoscale waveguides on this reflection. The ability to control photon transport in 1D waveguides coupled to spin systems would enable novel quantum network capabilities and the study of many-body effects emerging from long-range interactions. PMID- 27715122 TI - Persistent Directional Current at Equilibrium in Nonreciprocal Many-Body Near Field Electromagnetic Heat Transfer. AB - We consider the consequence of nonreciprocity in near-field heat transfer by studying systems consisting of magneto-optical nanoparticles. We demonstrate that, in thermal equilibrium, a nonreciprocal many-body system in heat transfer can support a persistent directional heat current, without violating the second law of thermodynamics. Such a persistent directional heat current cannot occur in reciprocal systems, and can only arise in many-body systems in heat transfer. The use of nonreciprocity therefore points to a new regime of near-field heat transfer for the control of heat flow in the nanoscale. PMID- 27715123 TI - Spin-Orbit-Coupled Correlated Metal Phase in Kondo Lattices: An Implementation with Alkaline-Earth Atoms. AB - We show that an interplay between quantum effects, strong on-site ferromagnetic exchange interaction, and antiferromagnetic correlations in Kondo lattices can give rise to an exotic spin-orbit coupled metallic state in regimes where classical treatments predict a trivial insulating behavior. This phenomenon can be simulated with ultracold alkaline-earth fermionic atoms subject to a laser induced magnetic field by observing dynamics of spin-charge excitations in quench experiments. PMID- 27715124 TI - Universal Scaling Laws for Dense Particle Suspensions in Turbulent Wall-Bounded Flows. AB - The macroscopic behavior of dense suspensions of neutrally buoyant spheres in turbulent plane channel flow is examined. We show that particles larger than the smallest turbulence scales cause the suspension to deviate from the continuum limit in which its dynamics is well described by an effective suspension viscosity. This deviation is caused by the formation of a particle layer close to the wall with significant slip velocity. By assuming two distinct transport mechanisms in the near-wall layer and the turbulence in the bulk, we define an effective wall location such that the flow in the bulk can still be accurately described by an effective suspension viscosity. We thus propose scaling laws for the mean velocity profile of the suspension flow, together with a master equation able to predict the increase in drag as a function of the particle size and volume fraction. PMID- 27715125 TI - Extended Propagation of Powerful Laser Pulses in Focusing Kerr Media. AB - Powerful incoherent laser pulses can propagate in focusing Kerr media much longer distances than can coherent pulses, due to the fast phase mixing that prevents transverse filamentation. This distance is limited by 4-wave scattering, which accumulates waves at small transverse wave numbers, where phase mixing is too slow to retain the incoherence and thus prevent the filamentation. However, we identify how this theoretical limit can be overcome by countering this accumulation through transverse heating of the pulse by random fluctuations of the refractive index. Thus, the laser pulse propagation distances are significantly extended, making feasible, in particular, the generation of unprecedentedly intense and powerful short laser pulses in a plasma by means of backward Raman amplification in new random laser regimes.

AB - Quantum jumps of a qubit are usually observed between its energy eigenstates, also known as its longitudinal pseudospin component. Is it possible, instead, to observe quantum jumps between the transverse superpositions of these eigenstates? We answer positively by presenting the first continuous quantum nondemolition measurement of the transverse component of an individual qubit. In a circuit QED system irradiated by two pump tones, we engineer an effective Hamiltonian whose eigenstates are the transverse qubit states, and a dispersive measurement of the corresponding operator. Such transverse component measurements are a useful tool in the driven-dissipative operation engineering toolbox, which is central to quantum simulation and quantum error correction. PMID- 27715127 TI - Entanglement of Distillation for Lattice Gauge Theories. AB - We study the entanglement structure of lattice gauge theories from the local operational point of view, and, similar to Soni and Trivedi [J. High Energy Phys. 1 (2016) 1], we show that the usual entanglement entropy for a spatial bipartition can be written as the sum of an undistillable gauge part and of another part corresponding to the local operations and classical communication distillable entanglement, which is obtained by depolarizing the local superselection sectors. We demonstrate that the distillable entanglement is zero for pure Abelian gauge theories at zero gauge coupling, while it is in general nonzero for the non-Abelian case. We also consider gauge theories with matter, and show in a perturbative approach how area laws-including a topological correction-emerge for the distillable entanglement. Finally, we also discuss the entanglement entropy of gauge fixed states and show that it has no relation to the physical distillable entropy.

U.S.A. 111, 670 (2014)] lipids and membrane proteins were observed to self-assemble into membrane protein polyhedral nanoparticles (MPPNs) with a well-defined polyhedral protein arrangement and characteristic size. We develop a model of MPPN self-assembly in which the preferred symmetry and size of MPPNs emerge from the interplay of protein-induced lipid bilayer deformations, topological defects in protein packing, and thermal effects. With all model parameters determined directly from experiments, our model correctly predicts the observed symmetry and size of MPPNs. Our model suggests how key lipid and protein properties can be modified to produce a range of MPPN symmetries and sizes in experiments. PMID- 27715129 TI - Superionic-Superionic Phase Transitions in Body-Centered Cubic H_{2}O Ice. AB - From first-principles molecular dynamics, we investigate the relation between the superionic proton conduction and the behavior of the O?H?O bond (ice VII^{'} to ice X transition) in body-centered-cubic (bcc) H_{2}O ice between 1300 and 2000 K and up to 300 GPa. We bring evidence that there are three distinct phases in the superionic bcc stability field. A first superionic phase characterized by extremely fast diffusion of highly delocalized protons (denoted VII^{''} hereinafter) is stable at low pressures. A first-order transition separates this phase from a superionic VII^{'}, characterized by a finite degree of localization of protons along the nonsymmetric O?H?O bonds. The transition is identified in structural, energetic, and elastic analysis. Upon further compression a second order phase transition leads to the superionic ice X with symmetric O?H?O bonds. PMID- 27715130 TI - Simultaneous Precision Gravimetry and Magnetic Gradiometry with a Bose-Einstein Condensate: A High Precision, Quantum Sensor. AB - A Bose-Einstein condensate is used as an atomic source for a high precision sensor. A 5*10^{6} atom F=1 spinor condensate of ^{87}Rb is released into free fall for up to 750 ms and probed with a T=130 ms Mach-Zehnder atom interferometer based on Bragg transitions. The Bragg interferometer simultaneously addresses the three magnetic states |m_{f}=1,0,-1?, facilitating a simultaneous measurement of the acceleration due to gravity with a 1000 run precision of Deltag/g=1.45*10^{-9} and the magnetic field gradient to a precision of 120 pT/m. PMID- 27715131 TI - Illuminating Molecular Symmetries with Bicircular High-Order-Harmonic Generation. AB - We present a general theory of bicircular high-order-harmonic generation from N fold rotationally symmetric molecules. Using a rotating frame of reference we predict the complete structure of the high-order-harmonic spectra for arbitrary driving frequency ratios and show how molecular symmetries can be directly identified from the harmonic signal. Our findings reveal that a characteristic fingerprint of rotational molecular symmetries can be universally observed in the ultrafast response of molecules to strong bicircular fields. PMID- 27715132 TI - Lateral Electron Confinement with Open Boundaries: Quantum Well States above Nanocavities at Pb(111). AB - We have studied electron states present at the Pb(111) surface above Ar-filled nanocavities created by ion beam irradiation and annealing. Vertical confinement between the parallel crystal and nanocavity surfaces creates a series of quantum well state subbands. Differential conductance data measured by scanning tunneling spectroscopy contain a characteristic spectroscopic fine structure within the highest occupied subband, revealing additional quantization. Unexpectedly, reflection at the open boundary where the thin Pb film recovers its bulk thickness gives rise to the lateral confinement of electrons. PMID- 27715133 TI - Bosonic Analogue of Dirac Composite Fermi Liquid. AB - We introduce a particle-hole-symmetric metallic state of bosons in a magnetic field at odd-integer filling. This state hosts composite fermions whose energy dispersion features a quadratic band touching and corresponding 2pi Berry flux protected by particle-hole and discrete rotation symmetries. We also construct an alternative particle-hole symmetric state-distinct in the presence of inversion symmetry-without Berry flux. As in the Dirac composite Fermi liquid introduced by Son [Phys. Rev. X 5, 031027 (2015)], breaking particle-hole symmetry recovers the familiar Chern-Simons theory. We discuss realizations of this phase both in 2D and on bosonic topological insulator surfaces, as well as signatures in experiments and simulations. PMID- 27715134 TI - Detection of Recurrent Fluorescence Photons. AB - We have detected visible photons emitted from the thermally populated electronic excited state, namely recurrent fluorescence (RF), of C_{6}^{-} stored in an electrostatic ion storage ring. Clear evidence is provided to distinguish RF from normal fluorescence, based on the temporal profile of detected photons synchronized with the revolution of C_{6}^{-} in the ring, for which the time scale is far longer than the lifetime of the intact photoexcited state. The relaxation (cooling) process via RF is likely to be commonplace for isolated molecular systems and crucial to the stabilization of molecules in interstellar environments. PMID- 27715136 TI - Quantum Correlations, Separability, and Quantum Coherence Length in Equilibrium Many-Body Systems. AB - Nonlocality is a fundamental trait of quantum many-body systems, both at the level of pure states, as well as at the level of mixed states. Because of nonlocality, mixed states of any two subsystems are correlated in a stronger way than what can be accounted for by considering the correlated probabilities of occupying some microstates. In the case of equilibrium mixed states, we explicitly build two-point quantum correlation functions, which capture the specific, superior correlations of quantum systems at finite temperature, and which are directly accessible to experiments when correlating measurable properties. When nonvanishing, these correlation functions rule out a precise form of separability of the equilibrium state. In particular, we show numerically that quantum correlation functions generically exhibit a finite quantum coherence length, dictating the characteristic distance over which degrees of freedom cannot be considered as separable. This coherence length is completely disconnected from the correlation length of the system-as it remains finite even when the correlation length of the system diverges at finite temperature-and it unveils the unique spatial structure of quantum correlations. PMID- 27715135 TI - Nonadditive Compositional Curvature Energetics of Lipid Bilayers. AB - The unique properties of the individual lipids that compose biological membranes together determine the energetics of the surface. The energetics of the surface, in turn, govern the formation of membrane structures and membrane reshaping processes, and thus they will underlie cellular-scale models of viral fusion, vesicle-dependent transport, and lateral organization relevant to signaling. The spontaneous curvature, to the best of our knowledge, is always assumed to be additive. We describe observations from simulations of unexpected nonadditive compositional curvature energetics of two lipids essential to the plasma membrane: sphingomyelin and cholesterol. A model is developed that connects molecular interactions to curvature stress, and which explains the role of local composition. Cholesterol is shown to lower the number of effective Kuhn segments of saturated acyl chains, reducing lateral pressure below the neutral surface of bending and favoring positive curvature. The effect is not observed for unsaturated (flexible) acyl chains. Likewise, hydrogen bonding between sphingomyelin lipids leads to positive curvature, but only at sufficient concentration, below which the lipid prefers negative curvature. PMID- 27715137 TI - Effect of occlusal plane control procedure on hyoid bone position and pharyngeal airway of hyperdivergent skeletal Class II patients. AB - OBJECTIVE: To evaluate the effect of occlusal plane control on the hyoid bone position and pharyngeal airway of hyperdivergent skeletal Class II patients during orthodontic treatment. MATERIALS AND METHODS: Cephalograms of 47 hyperdivergent skeletal Class II subjects with occlusal plane control (OPC), and another 50 subjects without occlusal plane control (NOPC) were selected to compare the effects of the occlusal plane control procedure. Lateral cephalograms before treatment (T1), immediately after treatment (T2), and an average of 12 months after treatment (T3) were obtained, and 17 measurements were analyzed in each group and compared between groups. RESULTS: With respect to the T2-T1 changes, the sagittal discrepancies in both groups were alleviated. In the OPC group, both the occlusal and mandibular plane angles decreased, accompanied by anterior and superior movement and counterclockwise rotation of the hyoid bone. The overall changes from T3 to T1 in each group exhibited trends similar to that induced by treatment. As for pharyngeal airway space alterations, no significant difference in OPC group was presented throughout treatment or retention periods. CONCLUSIONS: The customized occlusal plane control procedure was effective for hyperdivergent skeletal Class II patients: The occlusal plane rotated counterclockwise, followed by a counterclockwise rotation of the mandibular plane. The hyoid bone moved anteriorly and superiorly, accompanied by its counterclockwise rotation. However, this procedure did not induce significant alteration of the pharyngeal airway space. PMID- 27715138 TI - Diagnosis and management of lipoedema in the community. AB - Lipoedema is a chronic progressive adipose disorder that affects mainly women and presents as symmetrical enlargement of the buttocks and legs. It is commonly misdiagnosed as obesity or lymphoedema, but careful assessment will reveal a disproportionate enlargement below the waist which is resistant to dieting, sparing of the feet, legs are tender or painful to touch and bruise easily, there is occasional orthostatic oedema, and there is often significant psychological morbidity. Lipoedema is a oestrogen-regulated condition with onset around puberty in 78% of women, and there is often a strong family history. The condition is exacerbated by weight gain and there is increasing anecdotal evidence that women who are obese are seeking a diagnosis of lipoedema, either to procure NHS funded manual lymphatic drainage, or to medicalise their obesity and avoid acknowledging that the responsibility for their weight gain is lifestyle orientated. Management of lipoedema consists of accurate diagnosis, psychological care, management of orthostatic oedema, and prevention of progression through skin care and weight management.

AB - The aim of this study was to gain a comprehensive insight into the use of night time compression in the management of lymphoedema in patients who had been suffering from chronic lymphoedema for over 12 months. Data were collected and analysed from 94 patients, across five countries. Understanding user characteristics provided insight and understanding into how night-time compression regimens were initiated, products were used and benefits to the patient were reported. In addition to gaining an insight into user habits and night-time compression benefits, unmet needs were also identified. Positive outcomes from the use of night-time compression were reported, with all patients identifying benefits of using night-time compression. An increase in swelling was documented in 89% of all patients in this study group when night-time compression was not used. The study provided an opportunity to explore how lymphoedema affects patients, and how night-time compression can form part of a beneficial regime. PMID- 27715143 TI - Chronic oedema: its prevalence, effects and management. AB - Ageing affects not only individuals but also society. It occurs throughout the western world. The ageing process may lead to the development of conditions, such as chronic oedema, as well as comorbidities such as osteoarthritis. These comorbidities can make the management of chronic oedema even more difficult. This is an especially important consideration when tailoring individualised care plans, such as exercise, as conditions such as rheumatoid arthritis can limit patients' ability to manage their oedema. Despite challenges, education can improve patient outcomes when evidence-based practice is used. PMID- 27715145 TI - Selecting a compression wrap when treating lymphoedema.

PMID- 27715146 TI - 64Cu-PSMA-617 PET/CT Imaging of Prostate Adenocarcinoma: First In-Human Studies. AB - AIM: The prostate-specific membrane antigen (PSMA) is a cell surface protein, which is overexpressed in nearly all cases of prostate cancer (PCa). PET imaging with 68Ga-PSMA-HBED-CC has recently found widespread application in the diagnosis of recurrent PCa. In this study, the diagnostic potential of 64Cu-labeled PSMA ligand (PSMA-617) PET in patients with PCa has been investigated. MATERIALS AND METHODS: The study was conducted simultaneously at two nuclear medicine centers, Austria (Vienna, Center 1) and Germany (Bad Berka, Center 2). The patients (n = 29) included in this study were referred for PET (Center 1, 21 patients) or PET/CT (Center 2, 8 patients) imaging with either a high suspicion of recurrent disease or for possible surgical or PSMA radioligand therapy planning. PET images of the whole body were performed at 1 hour p.i. and additional images of the pelvis at 2 hours p.i. RESULTS: In 23 of 29 patients, at least one focus of pathological tracer uptake suspicious for primary disease in the prostate lobe or recurrent disease was detected. Among healthy organs, the salivary glands, kidneys, and liver showed the highest radiotracer uptake. Lesions suspicious for PCa were detected with excellent contrast as early as 1 hour p.i. with high detection rates even at low prostate-specific antigen (PSA) levels. CONCLUSION: The preliminary results of this study demonstrate the high potential of 64Cu-PSMA ligand PET/CT imaging in patients with recurrent disease and in the primary staging of selected patients with progressive local disease. The acquired PET images showed an excellent resolution of the detected lesions with very high lesion-to- background contrast. Furthermore, the long half-life of 64Cu allows distribution of the tracer to clinical PET centers that lack radiochemistry facilities for the preparation of 68Ga-PSMA ligand (satellite concept).

PMID- 27715253 TI - An Overview of Analytical Methods for the Determination of Monoamine Oxidase Inhibitors in Pharmaceutical Formulations and Biological Fluids. AB - Monoamine oxidase inhibitors (MAOIs) were the first type of antidepressant developed. MAOIs elevate the levels of norepinephrine, serotonin, and dopamine by inhibiting an enzyme called monoamine oxidase. They are also used in the treatment of Parkinson's disease, tuberculosis, and several other disorders. Therefore, it is very important to develop efficient analytical methods for monitoring and management. There are two isoforms of monoamine oxidase, MAO-A and MAO-B. In this article, analyses of MAOIs in pharmaceutical formulations and biological fluids were reviewed from 2000 to the present, including all types of chromatographic, spectrophotometric, electrophoretic, and voltammetric techniques, focusing on isoniazid, tranylcypromine, moclobemide, rasagiline, and selegiline. PMID- 27715254 TI - The Angiotensin-(1-7)/Mas Axis Improves Pancreatic beta-Cell Function in Vitro and in Vivo. AB - The angiotensin-converting enzyme 2/angiotensin (Ang)-(1-7)/Mas axis of the renin angiotensin system often opposes the detrimental effects of the angiotensin converting enzyme/Ang II/Ang II type 1 receptor axis and has been associated with beneficial effects on glucose homeostasis, whereas underlying mechanisms are mostly unknown. Here we investigate the effects of Ang-(1-7) and its receptor Mas on beta-cell function. Isolated islets from Mas-deficient and wild-type mice were stimulated with Ang-(1-7) or its antagonists and effects on insulin secretion determined. Islets' cytoplasmic calcium and cAMP concentrations, mRNA amounts of Ins1, Ins2, Pdx1, and Mafa and effects of inhibitors of cAMP downstream signaling were determined. Ang-(1-7) was also applied to mice by osmotic pumps for 14 days and effects on glucose tolerance and insulin secretion were assessed. Ang-(1-7) increased insulin secretion from wild-type islets, whereas antagonists and genetic Mas deficiency led to reduced insulin secretion. The Mas-dependent effects of Ang-(1-7) on insulin secretion did not result from changes in insulin gene expression or changes in the excitation-secretion coupling but from increased intracellular cAMP involving exchange protein activated directly by cAMP. Administration of Ang-(1-7) in vivo had only marginal effects on glucose tolerance in wild-type mice but still resulted in improved insulin secretion from islets isolated of these mice. Interestingly, although less pronounced than in wild types, Ang-(1-7) still affected insulin secretion in Mas-deficient islets. The data indicate a significant function of Ang-(1-7) in the regulation of insulin secretion from mouse islets in vitro and in vivo, mainly, but not exclusively, by Mas-dependent signaling, modulating the accessory pathway of insulin secretion via increase in cAMP. PMID- 27715255 TI - Pulse and Surge Profiles of Luteinizing Hormone Secretion in the Mouse. AB - Using a new tail-tip bleeding procedure and a sensitive ELISA, we describe here the patterns of LH secretion throughout the mouse estrous cycle; in ovariectomized mice; in ovariectomized, estradiol-treated mice that model estrogen-negative and -positive feedback; and in transgenic GNR23 mice that exhibit allele-dependent reductions in GnRH neuron number. Pulsatile LH secretion was evident at all stages of the estrous cycle, with LH pulse frequency being approximately one pulse per hour in metestrous, diestrous, and proestrous mice but much less frequent at estrus (less than one pulse per 4 h). Ovariectomy resulted in substantial increases in basal and pulsatile LH secretion with pulses occurring approximately every 21 minutes. Chronic treatment with negative feedback, estradiol-filled capsules returned LH pulse frequency to intact follicular phase levels, although pulse amplitude remained elevated. On the afternoon of proestrus, the LH surge was found to begin in a highly variable manner over a 4-hour range, lasting for more than 3 hours. In contrast, ovariectomized, estradiol-treated, positive-feedback mice exhibited a relatively uniform surge onset at approximately 0.5 hour prior to lights out. Gonadectomized wild-type and heterozygous GNR23 (~200 GnRH neurons) male mice exhibited an LH pulse every 60 minutes. Homozygous GNR23 mice (~80 GnRH neurons) had very low basal LH concentrations but continued to exhibit small amplitude LH pulses every 90 minutes. These studies provide the first characterization in mice of pulse and surge modes of LH secretion across the estrous cycle and demonstrate that very few GnRH neurons are required for pulsatile LH secretion. PMID- 27715256 TI - Recommendations to support informal carers of people living with motor neurone disease. AB - Informal carers are increasingly providing specialist care at home for people living with motor neurone disease. The carers may experience significant deterioration in their quality of life as a result of the physical and psychological burden they undertake. This systematic review seeks to provide evidence-based recommendations to enable healthcare professionals to support carers appropriately to maintain their wellbeing and to continue providing care at home. Inclusion criteria included articles focusing on the experience of informal carers of people with motor neurone disease, particularly when reporting on their perspective of professional services. Twenty-three studies were included and a thematic analysis was undertaken. Four key recommendations were identified: providing support, early access to palliative care, information regarding availability of services, and offering carers training for using specialist equipment. These recommendations offer healthcare professionals practical, cost effective suggestions to improve existing services.

AB - The health service is having to plan for an increasingly older population putting extra demand on services, with a greater emphasis on providing care at home. A health board in Wales brought in an Early Response Service, which assessed whether patients attending accident and emergency needed to be admitted to hospital or could receive care at home. This qualitative study looked at the experiences of both patients and staff members in both settings. A multiple case study was undertaken using semi-structured interviews. The theoretical framework was derived from Kolcaba's comfort theory and the bio-psycho-social model. Staff were identifying the most suitable patients for care at home and all hospital admissions were necessary, as the patients required greater medical/surgical intervention than those cared for at home.

Community nurses are ideally placed to provide care to all people with long-term conditions, from health promotion, prevention and encouraging self-care to caring for people with more complex needs, comorbidities and end-of-life care. Community nurses are an essential element of the multidisciplinary team and should take the lead in delivering complex care at home to people with long-term conditions, while maintaining a focus on developing self-care, empowerment, community engagement and acting as an advocate for clients and their carers.

AB - OBJECTIVE: It is estimated that road traffic accidents are globally responsible for approximately 1.2 million deaths and 20 to 50 million injuries. About 70% of traffic incidences (TIs) occur in developing countries and among countries with high TI rates; Iran is the first. The aim of this study was to measure the association between being responsible for a traffic accident and some vehicle, human; and environmental related factors in Yasuj, a city with a high incidence of road traffic injuries and deaths in Iran. METHODS: This is a time-, date-, and place-matched case-control study conducted in 2015 using all traffic accidents registered and investigated by police during 2012. In total, 194 drivers were considered the at-fault driver in a traffic accident and the 194 drivers in the same collisions were included in the analysis. RESULTS: Based on the results from multivariate conditional logistic regression, significant associations between vehicle maneuver (ORTurn to right or left/Moving forward = 11.10, 95% confidence interval [CI], 1.77-69.58, P = .01) and age (odds ratio [OR] = 1.11, 95% CI, 1.004-1.22, P = .04) and the chance of being an at-fault driver were found. CONCLUSION: Driver behavior-related interventions including training and law enforcement seem to be more effective in reducing road traffic accidents in Iran.

AB - The World Health Organization's (WHO's) leadership challenges can be traced to its first decades of existence. Central to its governance and practice is regionalization: the division of its member countries into regions, each representing 1 geographical or cultural area. The particular composition of each region has varied over time-reflecting political divisions and especially decolonization. Currently, the 194 member countries belong to 6 regions: the Americas (35 countries), Europe (53 countries), the Eastern Mediterranean (21 countries), South-East Asia (11 countries), the Western Pacific (27 countries), and Africa (47 countries). The regions have considerable autonomy with their own leadership, budget, and priorities. This regional organization has been controversial since its beginnings in the first days of WHO, when representatives of the European countries believed that each country should have a direct relationship with the headquarters in Geneva, Switzerland, whereas others (especially the United States) argued in favor of the regionalization plan. Over time, regional directors have inevitably challenged the WHO directors-general over their degree of autonomy, responsibilities and duties, budgets, and national composition; similar tensions have occurred within regions. This article traces the historical roots of these challenges. PMID- 27715304 TI - Whither WHO? Our Global Health Leadership.

AB - OBJECTIVES: To determine consumer and fast-food purchase characteristics associated with the purchase of a sugar-sweetened beverage, as well as calories and grams of sugar, for children at a fast-food restaurant. METHODS: We completed cross-sectional analyses of fast-food restaurant receipts and point-of-purchase surveys (n = 483) collected during 2013 and 2014 in New York City and Newark and Jersey City, New Jersey. RESULTS: Caregivers purchased beverages for half of all children in our sample. Approximately 60% of these beverages were sugar-sweetened beverages. Fast-food meals with sugar-sweetened beverages had, on average, 179 more calories than meals with non-sugar-sweetened beverages. Being an adolescent or male, having a caregiver with a high school degree or less, having a caregiver who saw the posted calorie information, ordering a combination meal, and eating the meal in the restaurant were associated with ordering a sugar-sweetened beverage. Purchases that included a combination meal or were consumed in the restaurant included more beverage grams of sugar and calories. CONCLUSIONS: Characteristics of fast-food purchases appear to have the largest and most important association to beverage calories for children at fast-food restaurants. Targeting fast-food restaurants, particularly combination meals, may improve childhood obesity rates. PMID- 27715309 TI - AJPH Global News.

AB - Surveying governmental public health practitioners is a critical means of collecting data about public health organizations, their staff, and their partners. A greater focus on evidence-based practices, practice-based systems research, and evaluation has resulted in practitioners consistently receiving requests to participate in myriad surveys. This can result in a substantial survey burden for practitioners and declining response rates for researchers. This is potentially damaging to practitioners and researchers as well as the field of public health more broadly. We have examined recent developments in survey research, especially issues highly relevant for public health practice. We have also proposed a process by which researchers can engage with practitioners and practitioner groups on research questions of mutual interest. PMID- 27715312 TI - How motorcycle helmets affect trauma mortality: Clinical and policy implications. AB - BACKGROUND: Motorcycles are the most popular vehicles in Taiwan, where more than 14.8 million motorcycles (1 motorcycle per 1.6 people) are in service. Despite the mandatory helmet law passed in 1997, less than 80% of motorcyclists in Taiwan wear helmets. OBJECTIVE: The objective of this study was to analyze the effect of using motorcycle helmets on fatality rates. METHODS: A clinical data set including 2,868 trauma patients was analyzed; the cross-sectional registration database was administered by a university medical center in Central Taiwan. A path analysis framework and multiple logistic regressions were used to estimate the marginal effect of helmet use on mortality. RESULTS: Using a helmet did not directly reduce the mortality rate but rather indirectly reduced the mortality rate through intervening variables such as the severity of head injuries, number of craniotomies, and complications during therapeutic processes. Wearing a helmet can reduce the fatality rate by 1.3%, the rate of severe head injury by 34.5%, the craniotomy rate by 7.8%, and the rate of complications during therapeutic processes by 1.5%. These rates comprise 33.3% of the mortality rate for people who do not wear helmets, 67.3% of the severe head injury rate, 60.0% of the craniotomy rate, and 12.2% of the rate of complications during therapeutic processes. DISCUSSION: Wearing a helmet and trauma system designation are crucial factors that reduce the fatality rate. PMID- 27715313 TI - No Dog Left Behind: A Hedonic Pricing Model for Animal Shelters. AB - Companion animal overpopulation is a growing problem in the United States. In addition to strays, an average of 324,500 nonhuman animals are relinquished to shelters yearly by their caregivers due to family disruption (divorce, death), foreclosure, economic problems, or minor behavioral issues. As a result, estimates of animals in shelters range from 3 million to 8 million, and due to overcrowding, euthanasia is common. This analysis seeks to determine the appropriate pricing mechanisms to clear animal shelters of dogs in the manner most desirable-that is, through adoption. Based on a survey of Michigan residents, it is clear there are a number of correlations between the traits of dogs and the individuals who care for them. Hedonic pricing models indicate that animal shelters need to proactively vary their pricing systems to discount particular traits, specifically for mixed-breed, older, and black dogs. Premiums can be charged for puppies, purebred dogs, and those who have received specific services such as microchipping. PMID- 27715314 TI - Using MMPI-2-RF Correlates to Elucidate the PCL-R and Its Four Facets in a Sample of Male Forensic Psychiatric Patients. AB - This study documents the associations between the MMPI-2-RF (Ben-Porath & Tellegen, 2008 ) scale scores and the Psychopathy Checklist Revised (PCL-R; Hare, 2003 ) facet scores in a forensic psychiatric sample. Objectives were to determine how the MMPI-2-RF scales might enhance substantive understanding of the nature of the 4 PCL-R facets and to discern possible implications for the treatment of psychopathic patients. A sample of 127 male forensic psychiatric offenders admitted to a Dutch forensic psychiatric hospital completed the PCL-R and the MMPI-2. Exploratory stepwise regression analyses assessed the prediction of the PCL-R total and its facet scores from MMPI-2-RF scales at its 3 hierarchical levels. Conceptually meaningful results emerged at each level of the MMPI-2-RF hierarchy, including several consistent differences between predictor sets across the facets. Interestingly, ideas of persecution (RC6) was a specific predictor of PCL-R Facet 2, a facet noted for its association with treatment failure. Results are compared and contrasted to the extant body of empirical work to date, and some tentative clinical implications are offered. PMID- 27715316 TI - Using the Research Domain Criteria Framework to Explore Associations Between MMPI 2-RF Constructs and Physiological Variables Assessed by Eye-Tracker Technology. AB - The National Institute of Mental Health has proposed a paradigm shift in the conceptualization of psychopathology, abandoning the traditional categorical model in favor of one based on hierarchically organized dimensional constructs (Insel et al., 2010 ). One explicit goal of this initiative, the Research Domain Criteria (RDoC) project, is to facilitate the incorporation of newly available neurobiologic variables into research on psychopathology. The Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011 ) represents a similar paradigm shift, also adopting a hierarchical arrangement of dimensional constructs. This study examined associations between MMPI-2-RF measures of psychopathology and eye-movement metrics. Participants were college students (n = 270) who completed the MMPI-2-RF and then viewed a sequence of 30-s video clips. Results show a pattern of positive correlations between pupil size and emotional/internalizing dysfunction scales when viewing video eliciting negative emotional reactions, reflecting greater arousability in individuals with higher scores on these measures. In contrast, when viewing stimuli depicting angry, threatening material, a clear pattern of negative correlations was found between pupil size and behavioral/externalizing trait measures. These data add to the construct validity of the MMPI-2-RF and support the use of the RDoC matrix as a framework for research on psychopathology. PMID- 27715317 TI - Treatment of substance use disorders in schizophrenia. AB - BACKGROUND: Substance use disorders (SUDs) represent a great barrier to functional recovery for individuals with schizophrenia. It is important to use research on treatment of SUDs in schizophrenia to guide treatment recommendations and program planning. OBJECTIVES: We review studies of pharmacological and psychosocial interventions to treat SUDs in individuals with schizophrenia. METHODS: The criteria used to select studies for inclusion are (1) the percentage of the sample with a schizophrenia spectrum diagnosis is at least 25%; (2) participants have a comorbid SUD or problem use of substances; (3) an intervention for SUD is provided; (4) a substance use-related outcome is measured; and (5) the study design enabled examination of pre-post outcome measures including open label trials, nonrandomized evaluations (quasi experimental designs, nonrandom assignment to groups), or randomized controlled trials. RESULTS: There are few psychopharmacology outcomes studies. Most have examined use of antipsychotic medications to treat SUDs in schizophrenia. Several trials have yielded positive findings for naltrexone in reducing drinking compared to placebo in this population. Motivational and cognitive-behavioral interventions are associated with decreased substance use in several trials. CONCLUSION: Treatment for SUDs is feasible within a range of settings and acceptable to many individuals with schizophrenia. All individuals with schizophrenia should be offered brief or more extended psychosocial interventions that incorporate discussion of personal reasons to change and training in cognitive-behavioral strategies to reduce use, cope with cravings and stress, and avoid relapse. Future research must include larger samples, longitudinal designs, and similar outcome measures across studies. PMID- 27715315 TI - Alzheimer's disease and chronic traumatic encephalopathy: Distinct but possibly overlapping disease entities. AB - BACKGROUND: Alzheimer's disease (AD) and chronic traumatic encephalopathy (CTE) have long been recognized as sharing some similar neuropathological features, mainly the presence of neurofibrilary tangles and hyperphosphorylated tau, but have generally been described as distinct entities. Evidence indicates that neurotrauma increases the risk of developing dementia and accelerates the progression of disease. Findings are emerging that CTE and AD may be present in the same patients. CLINICAL PRESENTATION: This study presents a series of previously unpublished cases, with one case demonstrating possible neurotrauma related AD, one pure CTE, and an example of a case exhibiting features of both AD and CTE. The future significance of this work lies not only in the confirmation of AD-CTE co-existence, but, more importantly, ways of generating a hypothesis about the possibility that CTE may accelerate AD development. Understanding the relationship between neurotrauma and neurodegenerative disease will help elucidate how distinct disease entities can co-exist in the same patient. It will ultimately require the use of pre-clinical animal models and repeat injury paradigms to investigate clinically relevant injury mechanisms. These models should produce a CTE-like phenotype that must be both neuropathologically and behaviourally similar to human disease. CONCLUSION: This case series and review of the literature presents a discussion of AD and CTE in the context of neurotrauma. It highlights recent work from repetitive neurotrauma models with an emphasis on those exhibiting a CTE-like phenotype. Potential mechanisms of interest shared amongst AD and CTE are briefly addressed and future experiments are advocated for to enhance understanding of CTE pathophysiology and the relationship between CTE and AD. PMID- 27715318 TI - Effect of anticipatory stress on placebo alcohol consumption in a bar laboratory. AB - BACKGROUND: Only one laboratory study has examined the relation between stress and alcohol use in an ecologically valid drinking context. In that prior study, drinking was measured after the stressful situation. OBJECTIVE: To examine the effect of an anticipatory stressor, and trait social anxiety on "alcohol" consumption in a bar laboratory. METHODS: College students aged 18 and older (N = 127) in same-sex groups of two or three participants took part in a study that ostensibly examined alcohol's effect on language fluency. Using a between subjects design, participants were randomly assigned to a stress or control condition. Participants in the stress condition anticipated giving a stressful speech for the fluency procedure, whereas those in the control group anticipated a nonstressful activity. Before the alleged fluency task, groups could order and consume mixed drinks ad lib in a bar laboratory. No beverages actually contained alcohol, but we used a validated procedure to ensure that participants included in these analyses were deceived. Primary analyses were performed with a hierarchical linear model (HLM) due to a substantial group/modeling effect. RESULTS: Counter to expectations, participants in the control group consumed more placebo alcohol than those in the stress condition. This main effect was moderated by past 3 months' drinks per week, such that the effect was attenuated (or reversed) among heavy drinkers. No main or interaction effects were observed for trait social anxiety. CONCLUSIONS: Some stressors (i.e., those invoking performance anxiety) may decrease consumption. People with higher levels of alcohol involvement might be especially motivated to drink for tension reduction purposes. PMID- 27715319 TI - Preliminary evaluation of a measure for reliable assessment of need for constant visual observation in adults with traumatic brain injury. AB - PRIMARY OBJECTIVE: To develop and provide initial validation of a measure for accurately determining the need for Constant Visual Observation (CVO) in patients with traumatic brain injury (TBI) admitted to inpatient rehabilitation. RESEARCH DESIGN: Rating scale development and evaluation through Rasch analysis and assessment of concurrent validity. METHODS AND PROCEDURES: One hundred and thirty four individuals with moderate-severe TBI were studied in seven inpatient brain rehabilitation units associated with the National Institute for Disability, Independent Living and Rehabilitation Research (NIDILRR) TBI Model System. Participants were rated on the preliminary version of the CVO Needs Assessment scale (CVONA) and, by independent raters, on the Levels of Risk (LoR) and Supervision Rating Scale (SRS) at four time points during inpatient rehabilitation: admission, Days 2-3, Days 5-6 and Days 8-9. OUTCOMES AND RESULTS: After pruning misfitting items, the CVONA showed satisfactory internal consistency (Person Reliability = 0.85-0.88) across time points. With reference to the LoR and SRS, low false negative rates (sensitivity > 90%) were associated with moderate-to-high false positive rates (29-56%). CONCLUSIONS: The CVONA may be a useful objective metric to complement clinical judgement regarding the need for CVO; however, further prospective study is desirable to further assess its utility in identifying at-risk patients, reducing adverse events and decreasing CVO costs. PMID- 27715320 TI - Association between chronotype and nonrestorative sleep in a college population. AB - Nonrestorative sleep (NRS), characterized by a lack of refreshment upon awakening, has received little attention in the sleep literature even though it can occur and cause impairment apart from other sleep difficulties associated with insomnia. The Restorative Sleep Questionnaire (RSQ) is one of the first validated self-report instruments for investigating NRS severity, presenting new opportunities to explore what factors predict and perhaps contribute to unrefreshing sleep. The present study sought to determine whether inherent circadian preference for morning or evening activity, known as chronotype, predicted restorative sleep in 164 college undergraduates who completed daily RSQs over 2 weeks. The participants who endorsed greater orientation to evening activity on the morningness-eveningness questionnaire reported significantly less average restorative sleep across their full sampling period, and this association was maintained after accounting for demographic factors, number of sleep-relevant psychiatric and medical diagnoses, sleep diary parameters, self-reported status as an insomniac and ratings of sleep quality. When analyses were conducted separately for weekday and weekend RSQ scores, eveningness predicted NRS independently of extraneous variables only during the workweek, not during Saturday and Sunday. These findings have implications for the developing conceptualization of NRS, and continue the work of elucidating the interconnections between common sleep disturbances and the circadian system. PMID- 27715321 TI - Changes in the diurnal rhythms of cortisol, melatonin, and testosterone after 2, 4, and 7 consecutive night shifts in male police officers. AB - Night work is associated with a large range of acute health problems and possibly also health consequences in the long run. Yet, only very few field studies specifically investigate the effects of consecutive night shift on key physiological regulatory systems. In this field study, we investigated the effects of consecutive night shifts on three hormones, melatonin, cortisol, and testosterone, among police officers at work. More specifically, the aim was to investigate how the diurnal rhythms of melatonin, cortisol, and testosterone responded to two, four, and seven consecutive night shifts and a corresponding number of days for recovery. The study was part of the "In the Middle of the Night" project and included 73 male police officers from five different police districts. The participants were exposed to three intervention conditions: "2+2": two consecutive night shifts followed by two consecutive day recovery days; "4+4": four consecutive night shifts followed by four consecutive recovery days; "7+7": seven consecutive night shifts followed by seven consecutive recovery days. On the last day with night shift and the last recovery day in each intervention, the participants collected saliva samples every 4th hour when awake. The diurnal rhythms of melatonin, cortisol, and testosterone were all affected differently by an increasing number of consecutive night shifts: the amplitude of the melatonin rhythm was suppressed by 4.9% per day (95% CI 1.4-8.2% per day; p = 0.006). The diurnal rhythm of cortisol phase was delayed with an increasing number of night shifts by 33 min/day (95% CI 18-48 min per day; p <= 0.001), but did not show any changes in amplitude. For the diurnal rhythm of testosterone, there was no effect of the number of consecutive night shifts and the diurnal rhythm completely followed the sleep/wake cycle. We found that there were no differences in the rhythms of melatonin, cortisol, and testosterone after 2, 4, and 7 recovery days, respectively. In conclusion, we found signs of desynchronization in terms of suppressed amplitude of melatonin and phase delay of salivary cortisol as a consequence of the increasing number of consecutive night shifts among police officers at work. Lack of synchronization has been suggested as a possible mechanism linking night work to disease, but this remains to be determined.

PMID- 27715322 TI - Effects of an Exercise Intervention in Frail Older Patients with Chronic Obstructive Pulmonary Disease Hospitalized due to an Exacerbation: A Randomized Controlled Trial. AB - The objective of this study was to determine whether an exercise intervention using a pedal exerciser is able to reduce disability in frail older patients with chronic obstructive pulmonary disease (COPD) during hospitalization due to an acute exacerbation. This study was a randomized, single-blind clinical trial. Fifty-eight frail older patients admitted to hospital due to an acute exacerbation of COPD (AECOPD) were included in this study. All patients received standard medical and pharmacological care. Patients assigned to the intervention group also received an exercise intervention. The main outcome measures were balance, muscle strength, and exercise capacity. Significant between-group differences were found in muscle strength (p = 0.028) and balance (p = 0.013) after the intervention. All the variables improved significantly (p < 0.05) in the exercise intervention group. In the intervention group, the mean difference in muscle strength between baseline and discharge was 10.47 N. Balance also improved, showing a mean difference of 7.56 seconds on the right leg and 6.57 seconds on the left leg. Exercise capacity improved as well, with a difference of 4.97 stands between baseline and discharge. All the variables showed impairment in the control group. In conclusion, an exercise intervention using a pedal exerciser during the hospital stay of frail elderly patients with an AECOPD improves muscle strength, balance, and exercise capacity. PMID- 27715324 TI - Social jetlag affects subjective daytime sleepiness in school-aged children and adolescents: A study using the Japanese version of the Pediatric Daytime Sleepiness Scale (PDSS-J). AB - The aim of this study was to elucidate the level of daytime sleepiness in Japanese school-aged children and adolescents, and to examine associated factors including sleep loss and social jetlag using the Japanese version of the Pediatric Daytime Sleepiness Scale (PDSS-J). After the linguistic validation of the PDSS-J with a multi-step translation methodology, consisting of forward translation, back translation, expert review and cognitive debriefing interviews, we conducted a psychometric validation for 492 students aged 11-16 years (46.7% boys) of public elementary school, junior high school and high school, using the PDSS-J, the Karolinska Sleepiness Scale (KSS), and bedtimes and wake-up times on school days and free days. Internal consistency (Cronbach's alpha) of the PDSS-J was 0.77, and the test-retest reliability demonstrated by the intraclass coefficient was 0.88. Multivariate logistic regression analysis revealed that both short sleep duration and social jetlag were identified as factors associated with daytime sleepiness, after adjustment for age and sex. PDSS-J scores were significantly higher in the group with large social jetlag with or without sufficient sleep duration than in the group with sufficient sleep duration and small social jetlag. The PDSS-J is an important tool for assessing daytime sleepiness, given its ease of administration and robust psychometric properties. The impact of not only sleep loss but also social jetlag on daytime sleepiness among school-aged children and adolescents must be fully taken into account. PMID- 27715325 TI - Social jet lag, chronotype and body mass index in 14-17-year-old adolescents. AB - The relationship between sleep duration and obesity in adolescents is inconclusive. This may stem from a more complex relationship between sleep and obesity than previously considered. Shifts toward evening preferences, later sleep-wake times and irregular sleep-wake patterns are typical during adolescence but their relationship to body mass index (BMI) has been relatively unexplored. This cross-sectional study examined associations between sleep duration, midpoint of sleep and social jet lag (estimated from 7 days of continuous actigraphy monitoring), and morningness/eveningness with BMIs (BMI z-scores) and waist-to height ratios in 14-17-year-old adolescents. Seventy participants were recruited from ninth and tenth grades at a public high school. Participants' characteristics were as follows: 74% female, 75% post-pubertal, 36% Hispanic, 38% White, 22% Black, 4% Asian and 64% free/reduced lunch participants with a mean age of 15.5 (SD, 0.7). Forty-one percent of the participants were obese (BMI >= 95th percentile); 54% were abdominally obese (waist-to-height ratio >= 0.5). Multivariable general linear models were used to estimate the association between the independent variables (school night sleep duration, free night sleep duration, midpoint of sleep (corrected), social jet lag and morningness/eveningness) and the dependent variables (BMI z-scores and waist-to height ratios). Social jet lag is positively associated with BMI z-scores (p < 0.01) and waist-to-height ratios (p = 0.01). Midpoint of sleep (corrected) is positively associated with waist-to-height ratios (p = 0.01). After adjusting for social jet lag, school night sleep duration was not associated with waist-to height ratios or BMI z-scores. Morningness/eveningness did not moderate the association between sleep duration and BMI z-scores. Findings from this study suggest that chronobiological approaches to preventing and treating obesity may be important for accelerating progress in reducing obesity rates in adolescents. PMID- 27715326 TI - Effects of long-term exposure to 900 megahertz electromagnetic field on heart morphology and biochemistry of male adolescent rats. AB - The pathological effects of exposure to an electromagnetic field (EMF) during adolescence may be greater than those in adulthood. We investigated the effects of exposure to 900 MHz EMF during adolescence on male adult rats. Twenty-four 21 day-old male rats were divided into three equal groups: control (Cont-Gr), sham (Shm-Gr) and EMF-exposed (EMF-Gr). EMF-Gr rats were placed in an EMF exposure cage (Plexiglas cage) for 1 h/day between postnatal days 21 and 59 and exposed to 900 MHz EMF. Shm-Gr rats were placed inside the Plexiglas cage under the same conditions and for the same duration, but were not exposed to EMF. All animals were sacrificed on postnatal day 60 and the hearts were extracted for microscopic and biochemical analyses. Biochemical analysis showed increased levels of malondialdehyde and superoxide dismutase, and reduced glutathione and catalase levels in EMF-Gr compared to Cont-Gr animals. Hematoxylin and eosin stained sections from EMF-Gr animals exhibited structural changes and capillary congestion in the myocardium. The percentage of apoptotic myocardial cells in EMF Gr was higher than in either Shm-Gr or Cont-Gr animals. Transmission electron microscopy of myocardial cells of EMF-Gr animals showed altered structure of Z bands, decreased myofilaments and pronounced vacuolization. We found that exposure of male rats to 900 MHz EMF for 1 h/day during adolescence caused oxidative stress, which caused structural alteration of male adolescent rat heart tissue.

AB - PRIMARY OBJECTIVES: To conduct video and statistical analysis on Rugby Union play, focusing mainly on the tackle, to establish the player to player configurations for significant direct head impacts and non-direct head impacts. RESEARCH DESIGN: Quantitative, observational cohort study. METHODS AND PROCEDURES: Video analysis of 52 significant direct head impacts (31 Tackle, 10 Ruck, 7 Dive and 4 Ground) and 40 non-direct head impact tackles from 2014/15 International Rugby Union matches. Relative risk, 95% CI and p-values were calculated for a range of tackle variables. MAIN OUTCOME AND RESULTS: Upper body tackles and lower body tackles accounted for 37% (19) and 23% (12) of cases, respectively, with the tackler as the head impacted player for 97% (30) of cases. The majority (81%) of tackle-related significant direct head impacts occurred in the second half of the game, with 63% of upper body tackle significant direct head impacts occurring in the final quarter. Tackler head placement and high speed tackles had statistical significance for causing tackle related significant direct head impacts as well as foot planting and difference in tackler and ball carrier mass for upper body tackles and ball carrier change in direction for lower body tackles. CONCLUSION: Tackle variables that statistically increased the risk of significant direct head impact were identified, which can aid player protection strategies. PMID- 27715328 TI - A review of implicit and explicit substance self-concept as a predictor of alcohol and tobacco use and misuse. AB - BACKGROUND: This paper provides an overview of the self-concept as it relates to substance use. Self-concept has a long history in psychological theory and research; however, substance self-concept (e.g., viewing one's self as a drinker or smoker) is an understudied area of research with the potential to expand existing conceptualizations of substance use, addiction, and prevention and treatment efforts, and should receive greater research attention. OBJECTIVES: First, we review and provide a theoretical framework of substance self-concept that draws from dual process models and distinguishes between implicit and explicit self-concept. Next, we summarize key findings related to substance use in the extant literature, focusing on alcohol and tobacco (smoking). RESULTS: Across both substances, there is converging evidence that substance self-concept is associated with substance use outcomes, including quantity and frequency of use and problems associated with use, and that change in substance self-concept is associated with recovery from substance misuse. Recommendations for the substance self-concept research agenda include routine assessment of substance self-concept, expanded use of implicit measures, investigation of moderators of substance self-concept, and targeting substance self-concept directly in prevention and intervention efforts. CONCLUSION: Ultimately, we suggest that substance self-concept is a promising, but understudied, construct. Greater research attention to substance self-concept could clarify its potential as an important risk factor for hazardous use and addiction as well as its utility as a prevention and treatment target. PMID- 27715329 TI - Preoperative Body Mass Index May Determine the Prognosis of Advanced Gastric Cancer. AB - Radical gastrectomy followed by adjuvant chemotherapy for advanced gastric cancer causes serious nutritional impairment. Our study evaluated the clinical impact of body mass index (BMI) on the long-term outcomes of advanced gastric cancer (stage II and III). We analyzed 211 cases of stage II and III gastric cancer between January 2005 and December 2010 at Chung-Ang University Hospital, Seoul, Korea. Patients were divided into four groups according to BMI: underweight, normal, overweight, and obese. In addition, we divided patients into two groups: BMI-High (BMI >= 23 kg/m2) vs. BMI-Low (BMI < 23 kg/m2). We assessed age, sex, tumor location, lymph node (LN) involvement, operation method, initial cancer stage, recurrence, and survival between the two groups. There was significant difference in overall survival (OS) between the underweight group and the other groups (P = 0.005). The survival of the BMI-High group was better than that of the BMI-Low group. The rate of cancer-related death in the BMI-High group was significantly lower than that in the BMI-Low group (cancer-related death: BMI-Low 27% vs. BMI High 12.6%, P = 0.022). Our findings suggest that preoperative BMI may have an influence on the long-term outcomes of advanced gastric cancer after radical surgery and chemotherapy. PMID- 27715330 TI - Sex and Drugs and Starting School: Differences in Precollege Alcohol-Related Sexual Risk Taking by Gender and Recent Blackout Activity. AB - Research has demonstrated a link between alcohol use and multiple forms of risky sexual behavior, particularly among college-age individuals. Studies have also linked heavy alcohol use to other problems, such as impaired consciousness resulting from an alcohol-induced blackout, which may impact sexual decision making. However, research has rarely examined sexual risk taking (SRT) in relation to blackouts, nor has it examined this construct during the precollege transition (i.e., the interval of time between high school graduation and college matriculation). This study examined the intersection between alcohol-involved SRT, blackouts, and gender in a sample of precollege individuals with prior alcohol use (N = 229; 54% male, 63% White). Results indicated that, despite drinking less per occasion, women reporting recent blackouts were at increased risk for experiencing unwanted, unsafe, and regretted sexual behaviors compared to men with recent blackouts and their peers with no recent blackouts. Women with recent blackouts also reported differences in alcohol expectancies that may increase their risk for experiencing negative consequences while drinking, including higher social expectancies and lower negative expectancies of danger. Future directions for research and implications for precollege interventions are discussed. PMID- 27715332 TI - Comment on "Milham & Stetzer (2016) Tumor-specific frequencies and ocular melanoma."

AB - OBJECTIVE: Young people regularly expose themselves to leisure noise and are at risk of acquiring tinnitus. This study examined the prevalence of leisure noise induced tinnitus among Flemish young adults as well as the relation with sociodemographic factors, health-related variables and attitudes and beliefs towards noise. DESIGN: A self-administered questionnaire was used to evaluate the presence of noise-induced tinnitus, the amount of leisure noise and attitudes towards noise and hearing protection. STUDY SAMPLE: 517 subjects between 18 and 30 years were included. RESULTS: Temporary and chronic tinnitus occurred in 68.5% and 6.4% of the sample, respectively. Chronic tinnitus was more prevalent in male subjects and associated with more hearing-related symptoms. Furthermore, subjects with chronic tinnitus were more aware of the risks of noise and the importance of hearing protection. Finally, higher levels of leisure noise were independently associated with chronic tinnitus. CONCLUSIONS: Tinnitus is observed frequently in young adults. Results also indicate that persons with chronic tinnitus were exposed to a higher noise dose during their lives. Longitudinal studies may be useful to evaluate whether the experience of chronic tinnitus has led to behavioural changes. These findings further underpin the importance of educating youth about the risks of leisure noise exposure. PMID- 27715333 TI - A Qualitative Exploration of the Premigration Victimization Experiences of Sexual and Gender Minority Refugees and Asylees in the United States and Canada. AB - Progress in analyzing and interpreting the concepts of sexual orientation and gender identity in the context of refugee law has contributed to a rise in individuals seeking asylum in such countries as the United States and Canada. However, few studies have examined the victimization experiences of sexual- and gender-identity forced migrants prior to their arrival in North America. This qualitative study used thematic analysis to explore the premigration adult victimization experiences of 26 lesbian, gay, and transgender individuals who obtained refugee, asylee, or withholding-of-removal status in the United States or Canada based on persecution for their sexual orientation and/or gender identity. Participants originated from countries in Asia, Africa, the Caribbean, Eastern Europe, Latin America, and the Middle East. Analysis revealed the following themes: living on the edge, adopting concealment strategies, routine victimization, and protectors as perpetrators. Participants described living in a constant state of hypervigilance, and they adopted numerous strategies to protect themselves from victimization. Despite the use of such strategies, participants experienced victimization by community members and state actors, leaving them no choice but to flee to ensure their safety and well-being. Findings are discussed using the ecological framework outlined by the World Health Organization (WHO). The discussion concludes with implications for international policy and clinical practice. PMID- 27715334 TI - The relationship between chronotype and personality among patients with alcohol dependence syndrome: Pilot study. AB - The study investigates the distribution of chronotypes among alcohol-dependent subjects and the relationship between personality and chronotype. Fifty-eight alcohol-dependent patients and 29 age-matched healthy controls were studied using Oginska's Chronotype Questionnaire (ChQ), Eysenck's Personality Questionnaire - Revised (EPQ-R), Selzer's Michigan Alcoholism Screening Test (MAST) and a sociodemographic status questionnaire designed by the authors. The alcohol dependent patients tended to be morning type, based on the morningness eveningness ChQ scale, with a weakly marked rhythm, based on the distinctness ChQ scale. Preference towards morningness was associated with older age, but no relation between chronotype and severity of alcohol dependence was found. A high amplitude of the rhythm was associated with higher neuroticism. Therefore, despite being in the minority, patients with a distinct circadian rhythm (i.e. with a high amplitude) are at greater risk of mood and anxiety disorders and hence should be given special consideration.

AB - Inhaled indacaterol/glycopyrronium fixed-dose combination (IND/GLY) is approved in over 80 countries, including the EU, Japan, Australia and Switzerland and the US. The LANTERN study evaluated the efficacy of IND/GLY compared with inhaled long-acting beta2-agonist (LABA)/inhaled corticosteroid (ICS) or salmeterol/fluticasone (SFC) in patients with moderate-to-severe COPD with a history of <=1 exacerbation in the previous year. Here we present the efficacy and safety of IND/GLY versus SFC in the Chinese cohort from the LANTERN study. LANTERN was a 26-week, multicenter, randomized, double-blind, double-dummy, parallel-group study conducted in patients with moderate-to-severe COPD with a history of <=1 exacerbation in the previous year. The patients were randomized (1:1) to once-daily IND/GLY (110/50 MUg) or twice-daily SFC (50/500 MUg). The primary endpoint was non-inferiority of IND/GLY versus SFC in terms of trough FEV1. Of the total 744 patients randomized in the LANTERN study, 598 (80.4%) were from Mainland China and randomized to IND/GLY (n = 298) or SFC (n = 300), and 553 (92.5%) completed the study. IND/GLY showed superiority over SFC with a statistically significant and clinically meaningful improvement in trough FEV1, FEV1 AUC0-4h, peak FEV1 and trough forced vital capacity (FVC) change from the baseline. Annualized rate of moderate or severe COPD exacerbations was significantly lower (43%) with IND/GLY compared with SFC (rate ratio: 0.57, p = 0.015). Overall, adverse events were lower for IND/GLY (34.6%) versus SFC (43.1%). IND/GLY was superior in achieving bronchodilation versus SFC in a Chinese subgroup of patients from this study.

AB - The extant literature reveals a considerable amount of research examining course work or technical training in psychological assessment, but a dearth of empirical research on assessment supervision. This study examined perspectives on current assessment supervisory practices in professional psychology through an online survey. Descriptive and qualitative data were collected from 125 survey respondents who were members of assessment-focused professional organizations and who had at least 1 year of supervision experience. Responses indicated a general recognition of the need for formal training in assessment supervision, ongoing training opportunities, and adherence to supervision competencies. Responses indicated more common use of developmental and skill-based models, although most did not regard any one model of assessment supervision as superior. Despite the recommended use of a supervision contract, only 65.6% (n = 80) of respondents use one. Discussion, directed readings, modeling, role-play, and case presentations were the most common supervisory interventions. Although conclusions are constrained by low survey response rate, results yielded rich data that might guide future examination of multiple perspectives on assessment supervision and ultimately contribute to curriculum advances and the development of supervision "best practices." PMID- 27715338 TI - N-Acetylcysteine and Desferoxamine Reduce Pulmonary Oxidative Stress Caused by Hemorrhagic Shock in a Porcine Model. AB - AIM OF THE STUDY: To investigate the pulmonary oxidative stress and possible protective effect of N-Acetylcysteine (NAC) and Desferoxamine (DFX)in a porcine model subjected to hemorrhagic shock. MATERIALS AND METHODS: Twenty-one pigs were randomly allocated to Group-A (sham, n = 5), Group-B (fluid resuscitation, n = 8) and Group-C (fluid, NAC and DFX resuscitation, n = 8). Groups B and C were subjected to a 40-min shock period induced by liver trauma, followed by a 60-min resuscitation period. During shock, the mean arterial pressure (MAP) was maintained at 30-40 mmHg. Resuscitation consisted of crystalloids (35 mL/kg) and colloids (18 mL/kg) targeting to MAP normalization (baseline values +/- 10%). In addition, Group-C received pretreatment with NAC 200 mg/kg plus DFX 2 g as intravenous infusions. Thiobarbituric Acid Reactive Substances (TBARS), protein carbonyls and glutathione peroxidase (GPx) activity were determined in lung tissue homogenates. Also, histological examination of pulmonary tissue specimens was performed. RESULTS: TBARS were higher in Group-B than in Group-A or Group-C: 2.90 +/- 0.47, 0.57 +/- 0.10, 1.78 +/- 0.47 pmol/MUg protein, respectively (p < 0.05). Protein carbonyls content was higher in Group-B than in Group-A or Group C: 3.22 +/- 0.68, 0.89 +/- 0.30, 1.95 +/- 0.54 nmol/mg protein, respectively (p > 0.05). GPx activity did not differ significantly between the three groups (p > 0.05). Lung histology was improved in Group-C versus Group-B, with less alveolar collapse, interstitial edema and inflammation. CONCLUSION: NAC plus DFX prevented the increase of pulmonary oxidative stress markers and protein damage after resuscitated hemorrhagic shock and had beneficial effect on lung histology. NAC/DFX combination may be used in the multimodal treatment of hemorrhagic shock, since it may significantly prevent free radical injury in the lung. PMID- 27715340 TI - Mechanisms behind Post-Thyroidectomy Hypocalcemia: Interplay of Calcitonin, Parathormone, and Albumin-A Prospective Study. AB - PURPOSE OF STUDY: Hypocalcemia after thyroidectomy is attributed to injury or ischemia to parathyroid glands. Transient hypocalcemia in thyroidectomy when parathyroids are preserved is not adequately explained. Release of calcitonin and hypoalbuminemia are two proposed reasons. Primary objective of this study was to find the change in calcitonin in the postoperative period after total thyroidectomy. Secondarily, hypocalcemia and its correlation with calcitonin, albumin, and parathormone were also studied. MATERIALS AND METHODS: This Cohort study was carried out at the general surgical department of a tertiary level teaching institution from April 2015 to December 2015. One hundred adult patients undergoing total thyroidectomy, with at least three parathyroids being preserved were included. Changes in calcium, calcitonin, albumin, and parathormone were studied based on preoperative levels and the values at 1, 6, 24, and 48 hr after surgery. RESULTS: Calcitonin increased at one hour after thyroidectomy and fell below preoperative levels subsequently. Parathormone showed a mild rise at one hour and normalized subsequently. Total calcium, corrected calcium, and albumin showed decline at one hour and recovered gradually over the next two days. At preoperative level, calcium had significant correlation with parathormone alone. Calcium levels at one hour had significant correlation with calcitonin. All post operative calcium levels had significant correlation with parathormone and the number of parathyroids preserved in situ without auto-transplantation. CONCLUSIONS: There is significant hypocalcemia within the first 24 hr after thyroidectomy, caused by calcitonin release and hypoalbuminemia. Preservation of maximum number of parathyroids in-situ can counter and normalize this hypocalcemia. PMID- 27715339 TI - Effect of Pirfenidone on Vascular Proliferation, Inflammation and Fibrosis in an Abdominal Adhesion Rat Model. AB - AIM: To study the efficacy of pirfenidone for prevention of postoperative adhesion formation in an adhesion rat model. MATERIALS AND METHODS: Eighteen female Wistar rats were subjected to right-sided parietal peritoneum and right uterine horn adhesion model. Rats were randomized into three groups: group 1 (control) (closure of midline abdominal incision without any agent administration), group 2 (closure of incision after intraperitoneal administration of pirfenidone), and group 3 (closure of incision and only oral administration of pirfenidone for 14 days). Relaparotomy was performed 14 days after the first surgery. Effect of pirfenidone on adhesion formation was assessed on light microscopy by scoring vascular proliferation, inflammation, fibrosis, and collagen formation in the scarred tissue. Effect of pirfenidone on inflammation was assessed by measurement of transforming growth factor-beta and interleukin-17 levels in scarred tissue. RESULTS: The degree of vascular proliferation (1.32 +/- 0.39 versus 2.34 +/- 0.46, p < 0.001), inflammation (1.60 +/- 0.70 versus 2.60 +/- 0.52, p < 0.01), and fibrosis (1.50 +/- 0.53 versus 2.40 +/- 0.52, p < 0.01) were less prominent in group 2 compared to group 1, respectively. Only vascular proliferation was found to be less prominent in group 3 compared to group 1 (1.60 +/- 0.42 versus 2.34 +/- 0.46, p < 0.01). Intraperitoneal and oral administration of pirfenidone reduced tissue levels of inflammatory markers (TGF-beta and IL-17) in parietal and visceral peritoneum compared to control group. Intraperitoneal administration of pirfenidone compared to oral administration was more effective in reducing tissue levels of inflammatory markers. CONCLUSION: Pirfenidone is an effective agent on the prevention of postoperative vascular proliferation, inflammation and fibrosis in scarred tissue particularly with intraperitoneal administration. PMID- 27715341 TI - Modulation of GLP-1 signaling as a novel therapeutic approach in the treatment of Alzheimer's disease pathology. AB - INTRODUCTION: Clinical studies suggest a link between peripheral insulin resistance and cognitive dysfunction. Post-mortem analyses of Alzheimer disease (AD) subjects revealed insulin resistance in the brain, suggesting a role of this condition in cognitive deficits observed in AD. In this review, we focus on the glucagon-like peptide-1 (GLP-1) signaling pathway, whose role in the brain is collecting increasing attention because of its association with insulin signaling activation. Areas covered: The role of GLP-1-mediated effects in the brain and how they are affected along the progression of AD pathology is discussed. Furthermore, we provide a comprehensive discussion about the use of GLP-1 mimetics drugs, which have been developed as a treatment for T2DM but seem to possess a number of other physiological properties, including neuroprotective and anti-inflammatory effects, that may be useful to slow AD progression. Expert commentary: The repurposing of antidiabetic drugs for the modulation of brain insulin resistance in AD appears to be of great interest. The beneficial effects on synaptogenesis, neurogenesis, and cell repair as well as the reduction of the chronic inflammatory response, and most importantly the reduction of amyloid plaques in the brain indicate that these drugs have promise as novel treatments for AD. PMID- 27715342 TI - Comparison of threshold estimation in infants with hearing loss or normal hearing using auditory steady-state response evoked by narrow band CE-chirps and auditory brainstem response evoked by tone pips. AB - OBJECTIVE: The objective of this study is to compare air-conduction thresholds obtained with ASSR evoked by narrow band (NB) CE-chirps and ABR evoked by tone pips (tpABR) in infants with various degrees of hearing loss. DESIGN: Thresholds were measured at 500, 1000, 2000 and 4000 Hz. Data on each participant were collected at the same day. STUDY SAMPLE: Sixty-seven infants aged 4 d to 22 months (median age = 96 days), resulting in 57, 52, 87 and 56 ears for 500, 1000, 2000 and 4000 Hz, respectively. RESULTS: Statistical analysis was performed for ears with hearing loss (HL) and showed a very strong correlation between tpABR and ASSR evoked by NB CE-chirps: 0.90 (n = 28), 0.90 (n = 28), 0.96 (n = 42) and 0.95 (n = 30) for 500, 1000, 2000 and 4000 Hz, respectively. At these frequencies, the mean difference between tpABR and ASSR was -3.6 dB (+/- 7.0), 5.2 dB (+/- 7.3), -3.9 dB (+/- 5.2) and -5.2 dB (+/- 4.7). Linear regression analysis indicated that the relationship was not influenced by the degree of hearing loss. CONCLUSION: We propose that dB nHL to dB eHL correction values for ASSR evoked by NB CE-chirps should be 5 dB lower than values used for tpABR. PMID- 27715343 TI - Curcumin reduces lung inflammation via Wnt/beta-catenin signaling in mouse model of asthma. AB - OBJECTIVES: Asthma is a chronic inflammatory, heterogeneous airway disease affecting millions of people around the world. Curcumin has been found to have anti-inflammatory and antifibrosis effects. Researchers reported that curcumin regulated Wnt/beta-catenin signaling in lots of cells. However, whether curcumin regulates the levels of Wnt/beta-Catenin signaling in lung tissues and DCs (dendritic cells) remains unclear. In this study, we assessed the effects of curcumin on DCs and asthma. METHODS: C57BL/6 mice immunized with OVA (ovalbumin) were challenged thrice with an aerosol of OVA every second day for 8 days. Dexamethasone or curcumin was administered intraperitoneally to OVA-immunized C57BL/6 mice on day 24 once a day for 9 days. Mice were analyzed for effects of curcumin on asthma, inflammatory cell infiltration and cytokine levels in lung tissue. DCs were isolated from mouse bone morrow. The surface markers CD40, CD86 and CD11c of DCs was detected by FACS (fluorescence activated cell sorting) and the function of DCs was detected by mixed lymphocyte reaction. The expression of GSK-3beta and beta-catenin was detected by Western Blot. RESULTS: Results showed that OVA increased the number of inflammatory factors in BALF (bronchoalveolar lavage fluid), elevated lung inflammation scores in mice. Curcumin dose dependently reversed the alterations induced by OVA in the asthmatic mice. Curcumin activated Wnt/beta-catenin signaling pathway in DCs and asthmatic mouse lungs. CONCLUSIONS: Curcumin could influence the morphology and function of DCs, ease asthma symptom and inflammatory reaction through the activation of Wnt/beta catenin signaling. These results provide new evidence new evidence for application of curcumin on asthma. PMID- 27715345 TI - Discontinuation of modern hormonal contraceptives: an Italian survey. AB - OBJECTIVES: The aim of the study was to examine, in a sample of Italian women, the rate of discontinuation of use of hormonal contraception. METHODS: In a retrospective cross-sectional study, data were collected from a chart review of 1809 women using or stopping the hormonal contraceptive prescribed by their physician. The name of the contraceptive and the reason for discontinuation were taken from the charts. The differences between the methods regarding reasons for discontinuation were analysed. RESULTS: Of the 1809 women examined, 34.9% had discontinued their hormonal contraception: 6.9% did so for non-method-related reasons, 20.5% due to minor side effects, 4.4% due to major side effects and 3.8% due to difficulties with compliance. Irregular bleeding, weight gain and headache were the main reasons reported for discontinuation. Pills containing 30 MUg or 20 MUg ethinylestradiol (EE) and the vaginal ring were the most used contraceptive methods. Women using the vaginal ring discontinued less frequently compared with pill users (p < .005). Pills containing 20 MUg and 30 MUg EE had the same discontinuation rate. Venous thrombosis was the most frequently reported major side effect leading to discontinuation. CONCLUSION: About one-third of women who used modern hormonal contraceptives discontinued the method. Although the percentage of women who gave up as a result of minor side effects was lower than it used to be, and the use of low doses of EE by the vaginal route has decreased the rate of discontinuation, physicians should counsel women about the possibility of side effects and encourage them to seek advice before stopping. PMID- 27715344 TI - Pharmacokinetics and pharmacodynamics of ticagrelor in the treatment of cardiac ischemia. AB - INTRODUCTION: After acute coronary syndromes (ACS), the so-called dual antiplatelet therapy (DAPT), which usually consists of low-dose of aspirin in combination with a thienopyridine (clopidogrel, prasugrel) or with a cyclopentyltriazolopyrimidine (ticagrelor), reduces the risk of ischemic events. Ticagrelor, un particular, is an effective drug as it isn' a prodrug, doesn't require metabolic activation and demonstrates a rapid onset and faster offset of action. Areas covered: This article evaluates the pharmacokinetics, efficacy, safety and tolerability of ticagrelor during DAPT after ACS and its potential use beyond the canonical twelve months after PCI. The review discusses studies comparing: ticagrelor and clopidogrel (DISPERSE, DISPERSE-2, PLATO, RESPOND Trial, ONSET/OFFSET Trials), ticagrelor and placebo (PEGASUS TIMI 54 Trial). Expert opinion: For ACS patients, the PLATO trial showed that ticagrelor was superior to clopidogrel in the reduction of cardiovascular death, myocardial infarction and stroke. PEGASUS TIMI 54 showed that patients in whom ischemic events and cardiovascular death outweigh the risk of life-threatening bleeding, may benefit from prolonged ticagrelor-based dual antiplatelet therapy, over 12 months. This strategy has been recently approved by the ACC/AHA guidelines. Further studies are needed to evaluate and eventually validate the role of the prolonged DAPT in patients treated with new generation stents. PMID- 27715346 TI - Suppression of RAGE and TLR9 by Ketamine Contributes to Attenuation of Lipopolysaccharide-Induced Acute Lung Injury. AB - The present study aimed to investigate the protective role of ketamine in lipopolysaccharide (LPS)-induced acute lung injury (ALI) by the inhibition of the receptor for advanced glycation end products (RAGE) and toll-like receptor 9 (TLR9). ALI was induced in rats by intratracheal instillation of LPS (5 mg/kg), and ketamine (5, 7.5, and 10 mg/kg) was injected intraperitoneally 1 h after LPS administration. Meanwhile, A549 alveolar epithelial cells were incubated with LPS in the presence or absence of ketamine. After 24 h, bronchoalveolar lavage fluid (BALF) and lung tissue were collected. Ketamine posttreatment at doses of 5, 7.5, and 10 mg/kg decreased LPS-induced evident lung histopathological changes, lung wet-to-dry weight ratio, and lung myeloperoxidase activity. In addition, posttreatment with ketamine-inhibited inflammatory cells and inflammatory mediators including tumor necrosis factor-alpha, interleukin-6, and high-mobility group box 1 in BALF. Furthermore, we demonstrated that ketamine-inhibited LPS induced RAGE and TLR9 protein up-expressions and the phosphorylation of I-kappaB alpha and nuclear factor-kappaB (NF-kappaB) p65 in vivo and in vitro. The results presented here suggest that the protective mechanism of ketamine may be attributed partly to decreased production of inflammatory mediators through the inhibition of RAGE/TLR9-NF-kappaB pathway. PMID- 27715347 TI - Crucial Conversations: An interprofessional learning opportunity for senior healthcare students. AB - Clinical errors due to human mistakes are estimated to result in 400,000 preventable deaths per year. Strategies to improve patient safety often rely on healthcare workers' ability to speak up with concerns. This becomes difficult during critical decision-making as a result of conflicting opinions and power differentials, themes underrepresented in many interprofessional initiatives. These elements are prominent in our interprofessional initiative, namely Crucial Conversations. We sought to evaluate this initiative as an interprofessional learning (IPL) opportunity for pre-licensure senior healthcare students, as a way to foster interprofessional collaboration, and as a method of empowering students to vocalise their concerns. The attributes of this IPL opportunity were evaluated using the Points for Interprofessional Education Score (PIPES). The University of the West of England Interprofessional Questionnaire was administered before and after the course to assess changes in attitudes towards IPL, relationships, interactions, and teamwork. Crucial Conversations strongly attained the principles of interprofessional education on the PIPES instrument. A total of 38 volunteers completed the 16 hours of training: 15 (39%) medical rehabilitation, 10 (26%) medicine, 7 (18%) pharmacy, 5 (13%) nursing, and 1 (2%) dentistry. Baseline attitude scores were positive for three of the four subscales, all of which improved post-intervention. Interprofessional interactions remained negative possibly due to the lack of IPL opportunities along the learning continuum, the hidden curriculum, as well as the stereotyping and hierarchical structures in today's healthcare environment preventing students from maximising the techniques learned by use of this interprofessional initiative. PMID- 27715348 TI - Plant-Based Nutraceutical Increases Plasma Catalase Activity in Healthy Participants: A Small Double-Blind, Randomized, Placebo-Controlled, Proof of Concept Trial. AB - Oxidative stress resulting from dietary, lifestyle and environmental factors is strongly associated with tissue damage and aging. It occurs when there is either an overproduction of reactive oxygen species (i.e., oxidants) or decreased bioavailability of antioxidants that can scavenge them. The objective of this 12 week double-blind placebo-controlled study was to assess the efficacy of a nutraceutical at augmenting antioxidant status. Healthy adults (25-45 y) were randomized to either a treatment group (Product B, n = 23) or a placebo group (control, n = 20). No significant effect of Product B was observed for anthropometric variables or markers of glucose and lipid regulation. Biomarkers of oxidative stress were likewise not altered following the 12-week intervention. Plasma catalase concentrations were significantly elevated following 12 weeks of Product B as compared to the control group (+6.1 vs. -10.3 nmol/min/mL, p = 0.038), whereas other measures of antioxidant capacity were not significantly different between the groups. Product B effectively augmented concentrations of the anti-aging antioxidant catalase in healthy adults. PMID- 27715349 TI - University and public health system partnership: A real-life intervention to improve asthma management. AB - OBJECTIVE: Asthma is under-diagnosed in many parts of the world. We aimed to assess the outcome of a capacitating program on asthma for non-specialist physicians and other healthcare professionals working in the public system in Ribeirao Preto, Brazil. METHODS: A group of 16 asthma specialists developed a one year capacitating program in 11 healthcare clinics in the Northern District of the city, which included lectures on asthma, training on inhalation device use and spirometry, and development of an asthma management protocol. Researchers visited one health unit 2-4 times monthly, working with doctors on patients' care, discussing cases, and delivering lectures. Asthma education was also directed to the general population, focusing on recognition of signs and symptoms and long-term treatment, including production of educational videos available on YouTube. Outcome measures were the records of doctors' prescriptions of individual asthma medications pre- and post-intervention. RESULTS: Prior to the program, 3205 units of inhaled albuterol and 2876 units of inhaled beclomethasone were delivered by the Northern District pharmacy. After the one-year program, there was increase to 4850 units (51.3%) for inhaled albuterol and 3526 units (22.6%) for inhaled beclomethasone. The albuterol increase followed the recommendation given to the non-specialist doctors by the asthma experts, that every patient with asthma should have inhaled albuterol as a rescue medication, by protocol. No increase was observed in other districts where no capacitating program was conducted. CONCLUSION: A systematic capacitating program was successful in changing asthma prescription profiles among non-specialist doctors, with increased delivery of inhaled albuterol and beclomethasone. PMID- 27715350 TI - A novel compartmentalised stent graft to isolate the perfusion of the abdominal organs. AB - Donation after cardiac death has been adopted to address the critical shortage of donor organs for transplant. Recovery of these organs is hindered by low blood flow that leads to permanent organ injury. We propose a novel approach to isolate the perfusion of the abdominal organs from the systemic malperfusion of the dying donor. We reasoned that this design could improve blood flow to organs without open surgery, while respecting the ethical principle that cardiac stress not be increased during organ recovery. Conditions within the stent were analysed using a computational fluid dynamics (CFD) method and validated on two prototypes in vitro. The hydrodynamic pressure drop across the stent was measured as 0.14-0.22 mmHg, which is a negligible influence. Device placement studies were also conducted on swine model fluoroscopically. All these results demonstrated the feasibility of rapidly isolating the perfusion to abdominal organs using a compartmentalised stent graft design. PMID- 27715351 TI - Yeast beta-Glucan Modulates Inflammation and Waist Circumference in Overweight and Obese Subjects. AB - Increased inflammation occurs with excessive adiposity and yeast beta-glucan modulates immune responses. This study investigated the potential effect of yeast beta-glucan on inflammatory cytokines in overweight/obese people. A randomized, double blinded, placebo-controlled, clinical trial design enrolled 44 overweight/obese participants with body mass index >=23 kg/m2, randomized to two groups receiving beta-glucan 477 mg/capsule (n = 22) or placebo (n = 22) orally for six weeks. At weeks one to two, participants received 1 beta-glucan or placebo capsule/day and at four weeks two tablets/day. Anthropometric changes, lipid profiles, liver and renal functions, and inflammatory cytokines were measured. beta-glucan reduced waist circumference (p = 0.037) and blood pressure (p = 0.006) compared with controls after six weeks of intervention. No statistical significance between groups was observed for triglyceride, cholesterol, lipid profile, liver and renal function, or energy and nutrient intake compared with controls at week six. beta-glucan increased interlukin-10 (IL-10), an anti-inflammatory cytokine, by 23.97% from baseline at week two (p < 0.001) and 31.12% at week six (p < 0.001) and was significantly increased compared with controls at week two (p < 0.001) until week six (p < 0.001). beta glucan reduced pro-inflammatory cytokines IL-6 at week six (p = 0.005) and tumor necrosis factor-alpha at week two (p = 0.037) compared with controls. Supplementation of yeast beta-glucan for six weeks modulated pro-cytokines that accelerate overweight/obese comorbidities and reduced blood pressure as well as waist circumference, the strong risk factors for cardiovascular disease, in overweight/obese subjects. Thus, beta-glucan might have the potential to decrease comorbid conditions associated with overweight/ obesity. PMID- 27715352 TI - Advancing interprofessional patient safety education for medical, nursing, and pharmacy learners during clinical rotations. AB - Clinical errors are common and can lead to adverse events and patient death. Health professionals must work within interprofessional teams to provide safe and effective care to patients, yet current curricula is lacking with regards to interprofessional education and patient safety. We describe the development and implementation of an interprofessional course aimed at medical, nursing, and pharmacy learners during their clinical training at a large academic medical centre. The course objectives were based on core competencies for interprofessional education and patient safety. The course was offered as recurring three 1-hour sessions, including case-based discussions and a mock root cause analysis. Forty-three students attended at least one session over a 7-month period. We performed a cross-sectional survey of participants to assess readiness for interprofessional learning and a before and after comparison of patient safety knowledge. All students reported a high level of readiness for interprofessional learning, indicating an interest in interprofessional opportunities. In general, understanding and knowledge of the four competency domains in patient safety was low before the course and 100% of students reported an increase in knowledge in these domains after participating in the course. PMID- 27715353 TI - Correlates of Condom Use Among Substance Using Older Seropositive MSM: Implications for Mental Health Practice. AB - The purpose of this study was to describe the correlates of condom use among a sample of N = 60 substance using seropositive men who have sex with (MSM). The mean age of the study participants was 52 ranging 50-75 years of age. Seventy percent of study participants reporting smoking marijuana, 62% using cocaine, 25% heroin, 37% alcohol, and 30% amphetamines. Among those reporting substance use, 75% reported it was a hassle to use condoms, 42% indicated pleasure decreased with condom use, 72% indicated safer sex is boring, 72% reported the idea of using condoms is unappealing, 78% reported condoms ruined sex, and 71% said condoms interfered with romance. A multiple logistic regression analysis revealed low self-esteem, relationship status, attitudes towards condom use, and depression predicted condom use chi2 = 20.79, df = 6, rho =.002. The study findings have implications for mental health nursing practice with seropositive African American MSM. PMID- 27715354 TI - Validated questionnaires heighten detection of difficult asthma comorbidities. AB - OBJECTIVE: Multiple extra-pulmonary comorbidities contribute to difficult asthma, but their diagnosis can be challenging and time consuming. Previous data on comorbidity detection have focused on clinical assessment, which may miss certain conditions. We aimed to locate relevant validated screening questionnaires to identify extra-pulmonary comorbidities that contribute to difficult asthma, and evaluate their performance during a difficult asthma evaluation. METHODS: MEDLINE was searched to identify key extra-pulmonary comorbidities that contribute to difficult asthma. Screening questionnaires were chosen based on ease of use, presence of a cut-off score, and adequate validation to help systematically identify comorbidities. In a consecutive series of 86 patients referred for systematic evaluation of difficult asthma, questionnaires were administered prior to clinical consultation. RESULTS: Six difficult asthma comorbidities and corresponding screening questionnaires were found: sinonasal disease (allergic rhinitis and chronic rhinosinusitis), vocal cord dysfunction, dysfunctional breathing, obstructive sleep apnea, anxiety and depression, and gastro oesophageal reflux disease. When the questionnaires were added to the referring clinician's impression, the detection of all six comorbidities was significantly enhanced. The average time for questionnaire administration was approximately 40 minutes. CONCLUSIONS: The use of validated screening questionnaires heightens detection of comorbidities in difficult asthma. The availability of data from a battery of questionnaires prior to consultation can save time and allow clinicians to systematically assess difficult asthma patients and to focus on areas of particular concern. Such an approach would ensure that all contributing comorbidities have been addressed before significant treatment escalation is considered. PMID- 27715355 TI - State-level medical and absenteeism cost of asthma in the United States. AB - OBJECTIVE: For medically treated asthma, we estimated prevalence, medical and absenteeism costs, and projected medical costs from 2015 to 2020 for the entire population and separately for children in the 50 US states and District of Columbia (DC) using the most recently available data. METHODS: We used multiple data sources, including the Medical Expenditure Panel Survey, U.S. Census Bureau, Kaiser Family Foundation, Medical Statistical Information System, and Current Population Survey. We used a two-part regression model to estimate annual medical costs of asthma and a negative binomial model to estimate annual school and work days missed due to asthma. RESULTS: Per capita medical costs of asthma ranged from $1,860 (Mississippi) to $2,514 (Michigan). Total medical costs of asthma ranged from $60.7 million (Wyoming) to $3.4 billion (California). Medicaid costs ranged from $4.1 million (Wyoming) to $566.8 million (California), Medicare from $5.9 million (DC) to $446.6 million (California), and costs paid by private insurers ranged from $27.2 million (DC) to $1.4 billion (California). Total annual school and work days lost due to asthma ranged from 22.4 thousand (Wyoming) to 1.5 million days (California) and absenteeism costs ranged from $4.4 million (Wyoming) to $345 million (California). Projected increase in medical costs from 2015 to 2020 ranged from 9% (DC) to 34% (Arizona). CONCLUSION: Medical and absenteeism costs of asthma represent a significant economic burden for states and these costs are expected to rise. Our study results emphasize the urgency for strategies to strengthen state level efforts to prevent and control asthma attacks. PMID- 27715356 TI - The cost-effectiveness of 5-FU-SA in the treatment of actinic keratoses of the face and scalp in the UK secondary care setting. AB - OBJECTIVE: The objective of this analysis was to estimate the relative cost effectiveness of Actikerall 1 (5-FU-SA) vs cryotherapy in a secondary care setting in the UK, for lesion-directed treatment in patients with actinic keratoses (AK) of the face and scalp. METHODS: The model was a simple decision tree, with a 6-month time horizon. The perspective was that of the UK National Health Service (NHS). Modeled treatment effects included reported per-patient histological clearance and recurrence rates. Cost inputs comprised professional consultation time and cost of medication. Health-related utility estimation followed previously published methodology. Adverse events were not modeled. The key data and model structural assumptions followed expected UK practice. One-way and probabilistic sensitivity analyses were conducted to assess structural and parameter uncertainty. RESULTS: 5-FU-SA was found to be less costly (-L204) and more effective (+0.001 QALY) in base case and sensitivity analyses. In the probabilistic analysis there was 100% probability of being cost-effective over cryotherapy at L20,000 willingness to pay. Cost of professional time was a key driver of the model outcome. 5-FU-SA remained dominant across a range of scenario analyses, including exploration of assumptions around setting of care. LIMITATIONS: The time horizon of the analysis was short and data were not extrapolated beyond the duration of the clinical trial; however, this approach is consistent with likely follow-up of an AK patient. The clinical outcomes observed in the trial were based on a large proportion of cryotherapy patients undergoing an additional cycle of treatment; this may not occur or be required in an experienced secondary care setting. CONCLUSION: 5-FU-SA could be considered as a cost-effective choice for treatment of AK lesions of the face and scalp in secondary and mixed care settings in the UK. Use of 5-FU-SA in patients who would otherwise be managed with cryotherapy has the potential to result in cost savings. PMID- 27715357 TI - Factors related to parental age of first concern in toddlers with autism spectrum disorder. AB - PURPOSE: The age of first concern (AOC) of parents of children with autism spectrum disorders (ASD) has substantial implications for early diagnosis and intervention. The current study sought to determine the average AOC, what types of first concerns are most common, and what factors predict earlier AOC in toddlers with ASD. METHODS: This study analyzed the predictive influence of the type of concern, symptom severity, medical diagnoses, and other independent variables on AOC among toddlers with ASD using multiple regressions. RESULTS: The mean AOC was found to be 13.97 months (SD = 7.86). The most commonly reported first concern was speech/language. First concerns related to communication, speech/language predicted later AOC, while motor concerns predicted earlier AOC. CONCLUSIONS: Concerns that are more closely related to social communication deficits characteristic of ASD predicted later AOC. The implications of these findings on screening/assessment and intervention are discussed. PMID- 27715358 TI - Critical Review on Eliminating Endodontic Dental Infections Using Herbal Products. AB - The main purpose of a root canal treatment is to eliminate the bacteria and their products from the pulp space. Chemomechanical preparation (chemical-refers to irrigating solutions, i.e., either synthetic chemicals or herbal solutions and mechanical-refers to instrumentation of a root canals with endodontic files) of a root canal system plays a major role in obtaining the rationale of root canal treatment. Various synthetic chemicals known as endodontic irrigants play a major role in disinfection, but also have undesirable properties like allergic potential, toxicity, unacceptable taste, etc. Today there is a major change in trend towards the use of natural herbal medicines as a part of dental treatment due to its easy availability, less toxicity, and cost effectiveness. This article aims to provide a comprehensive review of various herbal endodontic irrigants evaluated for their effectiveness in the disinfection of a root canal system. This literature review is conducted using electronic databases "PubMed," "Google Scholar," and "Scopus," and articles were limited to those in the English language and published between 1980 and 2014. PMID- 27715359 TI - Topical 5% 5-fluorouracil in the treatment of multifocal basal cell carcinoma of the face: A novel chemotherapeutic approach. AB - To determine the safety and efficacy of topical 5-fluorouracil (5-FU) 5% ointment in treatment of non-syndromic multifocal basal cell carcinoma. A 55-year-old male patient, with 8 hours of daily sun exposure, having histologically proven and radiologically non-syndromic, multifocal basal cell carcinoma with involvement of 6 sites on the face, was treated with topical 5-FU 5% ointment twice daily over all sites except the site involving lid margin to prevent corneal toxicity. Left lid lesion underwent wide surgical excision with 5-mm clear margins and reconstruction with nasal septal mucoperichondrium and local skin mobilization. Pharmacologic effects first appeared at 4 weeks and by 8 weeks, the lesions had scabbed and had fallen off with no induration but residual mild perilesional erythema. Patient had post-op histopathological clear margins and recovered uneventfully. No recurrence in 6 months. A topical 5-FU 5% ointment represents a paradigm shift in the treatment of BCC from invasive and disfiguring options (surgery and chemoradiotherapy) to cheap, convenient, effective, non-invasive, non-disfiguring topical chemotherapy. Topical 5% 5-FU is a safe and effective modality of treatment of superficial spreading multifocal basal carcinoma, especially lesions larger than 10 mm, where margins cannot be identified clearly and recurrent lesions. PMID- 27715360 TI - Going from "paper and pen" to ICT systems: Perspectives on managing the change process. AB - BACKGROUND: Lack of participation from staff when developing information and communication technologies (ICT) has been shown to lead to negative consequences and might be one explanation for failure. Management during development processes has rarely been empirically studied, especially when introducing ICT systems in a municipality context. OBJECTIVE: To describe and interpret experiences of the management during change processes where ICT was introduced among staff and managers in elderly care. DESIGN: A qualitative interpretive method was chosen for this study and content analysis for analyzing the interviews. RESULTS: "Clear focus-unclear process" demonstrated that focus on ICT solutions was clear but the process of introducing the ICT was not. "First-line managers receiving a system of support" gave a picture of the first-line manager as not playing an active part in the projects. First-line managers and staff described "Low power to influence" when realizing that for some reasons, they had not contributed in the change projects. "Low confirmation" represented the previous and present feelings of staff not being listened to. Lastly, "Reciprocal understanding" pictures how first-line managers and staff, although having some expectations on each other, understood each other's positions. CONCLUSIONS: Empowerment could be useful in creating an organization where critical awareness and reflection over daily practice becomes a routine. PMID- 27715361 TI - Association of emergency department albuterol dispensing with pediatric asthma revisits and readmissions. AB - INTRODUCTION: Although pediatric asthma continues to be a highly studied disease, data to suggest clear strategies to decrease asthma related revisits or readmissions is lacking. The purpose of our study was to assess the effect of emergency department (ED) direct dispensing of beta-agonist metered dose inhalers on pediatric asthma ED revisit and readmission rates. METHODS: We conducted a retrospective cohort study of pediatric patients discharged from the pediatric ED with a diagnosis of asthma. Our primary outcome measured the rate of asthma revisits to the ED or admissions to the hospital within 28 days. Logistic regression analysis was used to assess ED beta-agonist MDI dispensing and revisit and/or readmission as the outcome. RESULTS: A total of 853 patients met eligibility for inclusion in the study, with 657 enrolled in the Baseline group and 196 enrolled in the ED-MDI group. The Baseline group experienced a revisit and readmission rate of 7.0% (46/657) versus 2.6% (5/196) in the ED-MDI group, (p = 0.026). ED direct dispensing of MDIs was found to be independently associated with a decreased risk of revisit or readmission (odds ratio 0.37; 95% confidence interval 0.14-0.95). CONCLUSIONS: In our study, ED direct dispensing of beta agonist MDIs resulted in a reduction in 28-day revisit and readmission to the hospital. Further studies should be performed to evaluate the economic impact of reducing these revisits and readmissions against the costs of maintaining a dispensing program. Our findings may support modification of asthma programs to include dispensing MDIs from the emergency department. PMID- 27715362 TI - Cellular Infiltrate in Rheumatoid Arthritis-associated Paracentral Corneal Ulceration. AB - PURPOSE: To investigate an immunopathogenesis of central and paracentral corneal ulceration associated with rheumatoid arthritis. METHODS: Sparse infiltrating cells in the ulcer area were identified by immunohistochemistry applied to archived formalin fixed, paraffin embedded tissues that had been recovered from patients undergoing penetrating keratoplasty necessitated by rheumatoid associated central or paracentral corneal ulceration. RESULTS: Clinically, the ulcers presented as non-infiltrated lesions with a modicum of other ocular inflammation. Sparse T-lymphocytes were consistently identified in the subepithelial areas adjacent to the ulcer, with some neutrophils and macrophages in the stroma. B-lymphocytes were not detected. MHC Class II antigens reactivity was noted on some infiltrating cells and on corneal endothelium of two specimens. CONCLUSIONS: Immunohistochemistry of archival tissue facilitated detection and identification of sparse infiltrate in this infrequent corneal melting. Selective, consistent finding of T-lymphocyte infiltration in the ulcer area supports an immunopathogenesis of this clinical entity. PMID- 27715363 TI - Orbital medulloepithelioma in an adult patient: Radiation-induced second neoplasia? AB - Second cancers in survivors of hereditary retinoblastoma occur much more commonly than in the general population. This can be attributed both to the germline mutation of the RB gene and chemoradiation used for treatment of this paediatric cancer. Medulloepithelioma is an uncommon tumor of neuroectodermal origin, seen largely in the paediatric population and rarely reported in adults. Though the incidence of second malignancies is common in retinoblastoma, medulloepithelioma as a second malignancy in retinoblastoma survivors is rare, with only one case reported so far. Herein, we present a case of a 29-year-old patient presenting with medulloepithelioma of the right orbit, arising in the radiation field of previously treated retinoblastoma. This case was also peculiar in that though the origin of tumor was in the eyeball it had a very aggressive clinical course. PMID- 27715364 TI - Characterizing socially supportive environments relating to physical activity participation for young people with physical disabilities. AB - PURPOSE: To explore the experiences of young people with physical disabilities relating to social inclusion and physical activity, in order to describe the characteristics of social environments that support participation in physical activity. METHOD: An iterative, qualitative design employed in-depth, semi structured interviews with young people with physical disabilities aged 12-18 (n = 11). Data were analyzed using interpretive thematic analysis. RESULTS: Young people described several ways that their social environments help motivate and support them in their physical activity participation. These include providing: fair and equitable participation beyond physical accommodations; belonging through teamwork; and socially supported independence. CONCLUSIONS: Supportive social environments characterized by equitable participation, a sense of belonging, and opportunities for interdependence, play a critical role in promoting the health and well-being of young people with physical disabilities. These characteristics are important to consider in the design of both integrated and dedicated physical activity programs.

PMID- 27715365 TI - Rate of Retinal Detachment after Early Prophylactic Vitrectomy for Acute Retinal Necrosis. AB - PURPOSE: To compare the rate of retinal detachment after acute retinal necrosis in eyes that underwent early vitrectomy versus no early vitrectomy. METHODS: Charts of patients (61 eyes) who presented to Texas Retina Associates between January 1, 2006 and December 30, 2014 for acute retinal necrosis were reviewed. Charts with incomplete documentation or follow-up less than 6 months were excluded. Twenty-nine remaining eyes were divided into two groups: early vitrectomy and no early vitrectomy. Primary outcome measure was rate of retinal detachment. RESULTS: Out of 29 eyes, 12 underwent early vitrectomy within 30 days of diagnosis and 17 either underwent vitrectomy after 30 days or did not undergo prophylactic vitrectomy at all. Three out of 12 eyes (25%) developed retinal detachment in the early vitrectomy group versus 10 out of 17 eyes (59%) in the no early vitrectomy group (p = 0.076). CONCLUSIONS: Early vitrectomy within 30 days may prevent retinal detachment after acute retinal necrosis. PMID- 27715367 TI - A tunable local field potentials computer simulator to assess minimal requirements for phase-amplitude cross-frequency-coupling estimation. AB - The quantitative study of cross-frequency coupling (CFC) is a relevant issue in neuroscience. In local field potentials (LFPs), measured either in the cortex or in the hippocampus, how gamma-oscillation amplitude is modulated by changes in theta-rhythms-phase is thought to be important in memory formation. Several methods were proposed to quantify CFC, but reported evidence suggests that experimental parameters affect the results. Therefore, a simulation tool to support the determination of minimal requirements for CFC estimation in order to obtain reliable results is particularly useful. An approach to generate computer simulated signals having CFC intensity, sweep duration, signal-to-noise ratio (SNR), and multiphasic-coupling tunable by the user has been developed. Its utility has been proved by a study evaluating minimal sweep duration and SNR required for reliable theta-gamma CFC estimation from signals simulating LFP measured in the mouse hippocampus. A MATLAB(r) software was made available to facilitate methodology reproducibility. The analysis of the synthetic LFPs created by the simulator shows how the minimal sweep duration for achieving accurate theta-gamma CFC estimates increases as SNR decreases and the number of CFC levels to discriminate increases. In particular, a sufficient reliability in discriminating five different predetermined CFC levels is reached with 35-s sweep with SNR = 20, while SNR = 5 requires at least 140-s sweep. PMID- 27715368 TI - Improving social functioning and challenging behaviors in adolescents with ASD and significant ID: A randomized pilot feasibility trial of reciprocal imitation training in a residential setting. AB - There is a lack of effective social interventions for youths with ASD and co morbid intellectual disability (ID). A previous single-case design study indicated that reciprocal imitation training (RIT) may improve social interaction and challenging behavior in this population. The current pilot study examined the feasibility of conducting an RCT to investigate the effectiveness of RIT for improving social functioning and challenging behaviors in 20 adolescents with ASD and severe ID in a residential program. The assessment protocol was feasible. RIT was well-tolerated by the adolescents and implemented with fidelity by teaching staff. Preliminary findings indicate that treatment had moderate to large effects on social functioning and challenging behavior, with mixed findings for imitation skills. A larger RCT of RIT for this population is feasible and warranted. PMID- 27715369 TI - Drug interactions in HIV treatment: complementary & alternative medicines and over-the-counter products. AB - INTRODUCTION: Use of complementary and alternative medicines (CAMs) and over-the counter (OTC) medications are very common among HIV-infected patients. These products can cause clinically significant drug-drug interactions (DDIs) with antiretroviral (ARV) medications, thereby increasing risk for negative outcomes such as toxicity or loss of virologic control. Areas covered: This article provides an updated review of the different mechanisms by which CAM and OTC products are implicated in DDIs with ARV medications. Expert commentary: Much of the literature published to date involves studies of CAMs interacting with older ARV agents via the cytochrome P450 (CYP450) system. However, the HIV treatment and prevention arsenal is continually evolving. Furthermore, our elucidation of the role of non-CYP450 mediated DDIs with ARV medications is greatly increasing. Therefore, clinicians are well served to understand the various mechanisms and extent by which new ARV therapies may be involved in drug interactions with CAMs and OTC medications. PMID- 27715370 TI - An abbreviated scoring algorithm for the baby and infant screen for children with autism traits. AB - PURPOSE: Autism spectrum disorder (ASD) screening is recommended for all children aged 18-24 months. However, healthcare providers may be burdened with the responsibility of conducting these screens in addition to necessary services. Therefore, developing a time-efficient screener with sound psychometric properties is essential. METHODS: This study sought to update the abbreviated scoring algorithm of the Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT) and increase its clinical utility. Six thousand and three children with ASD or atypical development enrolled in an early intervention program participated. RESULTS: A 6-item algorithm with a cutoff score of 3 was found to be optimal and yielded a sensitivity of 0.960 and a specificity of 0.864. CONCLUSION: Sensitivity and specificity estimates were similar to that of the complete BISCUIT-Part 1; thus, the 6-item algorithm can reliably differentiate children at-risk for ASD requiring further assessment. The algorithm appears to be a promising tool for early identification. PMID- 27715371 TI - Flow cytometric analysis of platelet cyclooxygenase-1 and -2 and surface glycoproteins in patients with immune thrombocytopenia and healthy individuals. AB - Immature platelets may contain more platelet enzymes such as cyclooxygenase (COX) 1 and COX-2 than mature platelets. Patients with immune thrombocytopenia (ITP) have a higher fraction of immature platelets and can therefore be utilized as a biological model for investigating COX-1 and COX-2 platelet expression. The aims were to develop flow cytometric assays for platelet COX-1 and COX-2 and to investigate the COX-1 and COX-2 platelet expression, platelet turnover, and platelet glycoproteins in ITP patients (n = 10) compared with healthy individuals (n = 30). Platelet count and platelet turnover parameters (mean platelet volume (MPV), immature platelet fraction (IPF), and immature platelet count (IPC)) were measured by flow cytometry (Sysmex XE-5000). Platelet COX-1, COX-2, and the glycoproteins (GP)IIb, IX, Ib, Ia, and IIIa were all analyzed by flow cytometry (Navios) and expressed as median fluorescence intensity. COX analyses were performed in both whole blood and platelet rich plasma (PRP), whereas platelet glycoproteins were analyzed in whole blood only. ITP patients had significantly lower platelet count (55 * 109/L) than healthy individuals (240 * 109/L, p < 0.01), but a higher MPV (p = 0.03) and IPF (p < 0.01). IPC was similar for the two groups (p = 0.74). PRP had significantly lower MPV (p < 0.01) and significantly higher platelet count and IPC (both p-values <0.03) when compared with whole blood. IPF was similar for PRP and whole blood (p = 0.18). COX-1 expression was 10 times higher and COX-2 expression was 50% higher in PRP than in whole blood (pCOX-1 < 0.01, pCOX-2 < 0.01). Platelet COX-1 expression was higher in ITP patients than healthy individuals using whole blood (pCOX-1 < 0.01) and PRP, though this was nonsignificant in PRP (pCOX-1 = 0.17). In ITP patients, positive correlations were found between platelet turnover and COX-1 expression (all p-values <0.01, rho = 0.80-0.94), whereas healthy individuals showed significant though weaker correlations between platelet turnover and COX-1 and COX-2 expressions (all p-values <0.03, rho = 0.44-0.71). GPIIb, IX, and Ib expression was increased in ITP patients compared with healthy individuals (all p values < 0.03). GPIIb, IX, Ib, and IIIa showed positive correlations with platelet turnover in ITP patients (all p-values <0.02, rho = 0.71-0.94), but weak and nonsignificant correlations in healthy individuals (all p-values >0.14, rho = 0.11-0.28). In conclusion, ITP patients expressed higher COX-1 and platelet glycoprotein levels than healthy individuals. COX-1 and platelet glycoproteins demonstrated positive correlations with platelet turnover in ITP patients. In healthy individuals, COX-1 and COX-2 expression correlated positively with platelet turnover. PRP was more sensitive compared with whole blood as regards determination of COX. Therefore, PRP is the recommended matrix for investigating COX-1 and COX-2 in platelets. PMID- 27715372 TI - Aggressive esthesioneuroblastoma with divergent differentiation: A taxonomic dilemma. AB - The authors describe an esthesioneuroblastoma (olfactory neuroblastoma) that occurred within the nasal cavity and brain in a 31-year-old man. Following excision, the tumor recurred in the left orbit and in mediastinal lymph nodes. Treatment included orbital excision and systemic chemotherapy. Histopathology showed a high-grade neuroepithelial tumor with positive immunohistochemical markers for neuroendocrine and epithelial components, an unusual combination raising issues concerning taxonomy. PMID- 27715373 TI - Cytomegalovirus Retinitis as the First Manifestation of Good Syndrome. PMID- 27715374 TI - Morphological and Functional Retinal Assessment in Epiretinal Membrane Surgery. AB - PURPOSE: To analyze functional and morphological findings after surgery for idiopathic epiretinal macular membrane (IEMM). MATERIALS AND METHODS: Twenty eyes of 20 patients affected by IEMM underwent 23-Gauge surgery. Morphological and functional examinations were assessed at baseline and at 30, 90, and 180 days after surgery. SD-OCT evaluated foveal morphology and thickness, photoreceptor inner/outer segment junction, and external limiting membrane. Functional assessment evaluated visual acuity, retinal sensitivity, and fixation patterns. Statistical analysis was performed with the Student's t test and Pearson correlation test. RESULTS: Mean central retinal thickness (CRT), visual acuity (VA), and retinal sensitivity (RS) at baseline were respectively 494.90 +/- 38.73 um, 0.55 +/- 0.08 LogMAR, and 11.13+/-1.02; after surgery, at day 180, we observed a significant decrease in mean CRT to 326.90+/-32.68 um, an increase in mean VA to 0.33 +/- 0.05 LogMAR (p < 0.05), and in mean RS to 13.25 +/- 0.73 dB (p < 0.05). A stable fixation increased from 40% of patients at baseline to 75% of patients at day 180 (p < 0.05). DISCUSSION: IEMM surgery results in continuous improvement in visual function, not only at month one but also beyond month six, due to the progressive reduction of residual intraretinal edema and recomposition of retinal layers. PMID- 27715375 TI - Changes in the Macular Ganglion Cell Complex Thickness and Central Macular Thickness after Argon Laser Panretinal Photocoagulation. AB - PURPOSE: To evaluate the changes in the macular ganglion cell complex (GCC) thickness and central macular thickness (CMT) as measured by spectral domain optical coherence tomography (OCT) post-argon laser panretinal photocoagulation (PRP). METHODS: The medical records of 25 patients with proliferative diabetic retinopathy (PDR) who underwent PRP, 29 patients with non-proliferative diabetic retinopathy (NPDR), and 29 patients with diabetes but without diabetic retinopathy (DR) were analyzed. The patients who received PRP were followed up for one year. The follow-up measurements were evaluated at baseline, and months 1, 6, and 12 post-argon laser PRP. The baseline values of CMT and GCC thickness were compared among the groups to assess changes with PRP therapy. RESULTS: The CMT gradually increased in months 1 and 6 and then decreased; however, it was significantly higher than the baseline value at month 12 in the PDR group post PRP. The GCC thickness also increased at months 1 and 6 in almost all segments of the macula, but at month 12 decreased to the baseline value. There was no correlation between the increasing thickness of the macula and change in the GCC thickness post-PRP period in the PDR group. In addition, no significant correlation was detected between the GCC thickness and best-corrected visual acuity during all follow-up visits. CONCLUSIONS: GCC thickness increased significantly until month 6 compared with baseline values in most of the macular segments post-PRP in the PDR group. The GCC thickness at month 12 was not different from the baseline thickness in any of the macular segments. PMID- 27715376 TI - 1.2% Rosuvastatin and 1.2% Atorvastatin Gel Local Drug Delivery and Redelivery in the Treatment of Class II Furcation Defects: A Randomized Controlled Clinical Trial. AB - BACKGROUND: Statins are one of the lipid-lowering drugs that help in reducing cholesterol levels in the body by specifically inhibiting 3-hydroxy-3 methylglutaryl coenzyme A reductase, which is a rate-limiting enzyme for cholesterol synthesis. Rosuvastatin (RSV) and atorvastatin (ATV) have shown bone stimulatory and anti-inflammatory effects. The present study aims to explore efficacy of 1.2% RSV and 1.2% ATV gels as a local drug delivery and redelivery system adjunct to scaling and root planing (SRP) for treatment of Class II furcation defects. METHODS: Ninety patients with mandibular buccal Class II furcation defects were randomly allocated to three treatment groups: 1) SRP with placebo gel (group 1); 2) SRP with 1.2% RSV gel (group 2); and 3) SRP with 1.2% ATV gel (group 3). Clinical and radiographic parameters were recorded at baseline and after 6 months. Gels were redelivered at the respective sites at a 6-month recall appointment. All clinical and radiographic parameters were recorded again after 3 months (i.e., 9 months from baseline). RESULTS: Greater mean probing depth (PD) reduction and greater mean gain in relative vertical clinical attachment level (CAL) and relative horizontal CAL were seen in the RSV group than in the ATV group at 6 and 9 months. Significantly greater mean percentage of defect depth reduction (DDR) was found in the RSV group (30.80% +/- 8.35%, 41.86% +/- 6.76%) than in the ATV group (25.54% +/- 8.89%, 34.31% +/- 8.04%) at 6 and 9 months, respectively. CONCLUSION: The RSV group shows significant improvement in all clinical parameters and significantly greater DDR compared with the ATV group in treatment of mandibular Class II furcation defects as an adjunct to SRP. PMID- 27715378 TI - Relationship between the sensation of activity limitation and the results of functional assessment in asthma patients. AB - OBJECTIVE: In asthma patients, the assessment of activity limitation is based on questions evaluating how limited the patient feels in their activities. However, the lack of functional data complicates the interpretation of the answers. We aimed to evaluate the intensity of relationships between the patient's perception of activity limitation and the results of several functional tests. METHODS: Twenty patients complaining of asthma exacerbation were invited to complete three scores (Chronic Respiratory Disease questionnaire, Asthma Control Questionnaire, Hospital Anxiety and Depression scale). They also underwent lung function measurements, a 6-minute walk test and a cardio-pulmonary exercise test. In addition, physical activity was studied by actigraphy. Spearman's rank correlation coefficients between the patient's perception of activity limitation and each of the other parameters were analysed. RESULTS: Five parameters were significantly correlated with the perception of activity limitation: ACQ question 4, related to dyspnea (rs 0.74, p < 0.001); Emotion domain of the Chronic Respiratory Disease questionnaire (rs -0.57, p = 0.02); HAD anxiety (rs 0.48, p = 0.032); HAD depression (rs 0.46, p = 0.041); ACQ question 6, related to reliever use (rs 0.46, p = 0.046). No parameters from the lung function test, 6MWT, CPET or actigraphy, were significantly correlated with the perception of activity limitation. CONCLUSIONS: In response to questions about limitation of activity, patients do not specifically answer mentioning physical limitation but rather the psychological burden associated with this constraint. PMID- 27715377 TI - Trunk deformity evaluation based on 3D measurements of front body surface landmarks in people with severe physical disabilities. AB - PURPOSE: To assess reliability and validity of a trunk deformity evaluation method expressed as rotational and lateral lean angles between the upper and the lower trunk and between the lower trunk and the pelvis using 3D positions of six front body surface landmarks. METHODS: Inter- and intra-rater reliabilities of the proposed method in adults with typical development (n = 22) were assessed, and its validity was also assessed through correlations between the Cobb angle and the analyzed trunk deformity parameters in adults with severe physical disabilities (n = 22). RESULTS: The mean differences between two raters and between the initial and second measures were within 2 degrees . Moderate correlations were found between the Cobb angle and both the upper and the lower trunk lateral lean angle and the upper trunk rotation angle. CONCLUSIONS: The proposed trunk deformity evaluation appears to be a reliable and valid approach for bedridden people with physical disabilities. PMID- 27715379 TI - The origins of major platelet receptor nomenclature. AB - The nomenclature of the major platelet receptors may appear complex, but in fact there are logical reasons why it developed in the way it did. In this short review, I describe the origins of this nomenclature, how it developed as more information became available and as relationships were established with receptors on other types of cells. Difficulties have also arisen with alternative nomenclature systems and the various equivalences with these are described and listed. There remain areas such as immunology and transfusion where the accepted nomenclature leaves something to be desired, but it is unlikely that major changes will occur. PMID- 27715380 TI - Ocular Manifestations, Conventional Fundus Fluorescein Angiographic Findings, and Relationship Between Angiographic Findings and Visual Acuity in Behcet's Disease. AB - PURPOSE: Evaluating the ocular manifestation and fundus fluorescein angiography (FA) findings of patients with Behcet's disease as well as the relationship between visual acuity and angiographic findings. METHODS: Retrospective chart review of patients with Behcet's disease seen at the Farabi Eye Hospital. RESULTS: Forty-six patients (92 eyes) with mean age of 33.41 +/- 10.67 were included. The most frequent presenting symptom and sign were reduced vision (76%) and uveitis (87%), respectively. Panuveitis was the most frequent type of uveitis (76%). Among patients with FA, vasculitis was the most common finding (87%) and it was significantly more severe among patients with visual acuity less than 20/200. Macular leakage (P = 0.001), arterial narrowing (P = 0.000), and posterior retinal vasculitis (P = 0.002) on FA were all associated with worsening final visual acuity. CONCLUSION: The most common ocular findings in Behcet's disease were panuveitis and vasculitis. Location of vasculitis, arterial narrowing, and macular leakage on initial FA may predict visual prognosis. PMID- 27715381 TI - Meniscal biology in health and disease. AB - The knee is a fascinating yet complex joint. Researchers and clinicians agree that the joint is an organ comprised of highly specialized intrinsic and extrinsic tissues contributing to both health and disease. Key to the function and movement of the knee are the menisci, exquisite fibrocartilage structures that are critical structures for maintaining biological and biomechanical integrity of the joint. The biological/physiological functions of the menisci must be understood at the tissue, cellular and even molecular levels in order to determine clinically relevant methods for assessing it and influencing it. By investigating normal and pathological functions at the basic science level, we can begin to translate data to patients. The objective of this article is to provide an overview of this translational pathway so that progression toward improved diagnostic, preventative, and therapeutic strategies can be effectively pursued. We have thoroughly examined the pathobiological, biomarker, and imaging aspects of meniscus research. This translational approach can be effective toward optimal diagnosis, prevention, and treatment for the millions of patients who suffer from meniscal disorders each year. PMID- 27715382 TI - Comparing two methods to promote generalization of receptive identification in children with autism spectrum disorders. AB - PURPOSE: The purpose of our study was to compare the effects of serial and concurrent training on the generalization of receptive identification in children with autism spectrum disorders (ASD). METHODS: We taught one to three pairs of stimulus sets to nine children with ASD between the ages of three and six. One stimulus set within each pair was taught using concurrent training and the other using serial training. We alternated the training sessions within a multielement design and staggered the introduction of subsequent pairs for each participant as in a multiple baseline design. RESULTS: Overall, six participants generalized at least one stimulus set more rapidly with concurrent training whereas two participants showed generalization more rapidly with serial training. CONCLUSIONS: Our results differ from other comparison studies on the topic and indicate that practitioners should consider assessing the effects of both procedures prior to teaching receptive identification to children with ASD. PMID- 27715383 TI - Life in lights: Tracking mitochondrial delivery to lysosomes in vivo. AB - The past decade has seen an intensive and concerted research effort into the molecular regulation of mitophagy, the selective autophagy of mitochondria. Cell based studies have implicated mitophagy in the pathology of diverse conditions ranging from cancer to neurodegeneration. However, a definitive link between mitophagy and the etiology of human disease remains to be demonstrated. Moreover, we do not know how pervasive mammalian mitophagy is in vivo and fundamental questions remain unanswered. For example, is mitophagy common to all tissues under basal conditions or does it only occur in highly oxidative tissues under stress? This paucity of knowledge is largely due to a lack of experimentally tractable tools that can measure and monitor mitophagy in tissues. Our recent work describes the development of mito-QC, a mouse model to study mitophagy at single cell resolution in vivo. PMID- 27715384 TI - Allogeneic hematopoietic stem cell transplantation for nonmalignant hematologic disorders using chemotherapy-only cytoreductive regimens and T-cell-depleted grafts from human leukocyte antigen-matched or -mismatched donors. AB - Nonmalignant hematologic disorders (NMHD) of childhood comprise a variety of disorders, including acquired severe aplastic anemia and inherited marrow failure syndromes. Patients with high-risk NMHD without matched related donors fare poorly with allogeneic hematopoietic alternative donor stem cell transplantation (allo-HSCT) and are at high risk for developing graft-versus-host disease following unmodified grafts. The authors retrospectively analyzed data on 18 patients affected by NMHD, lacking a human leukocyte antigen (HLA)-identical sibling donor, who underwent an alternative donor allo-HSCT at their institution between April 2005 and May 2013. Fifty percent of the patients had received prior immunosuppressive therapy, 72% had a history of infections, and 56% were transfusion dependent at the time of transplant. Cytoreduction included a combination of 3 of 5 agents: fludarabine, melphalan, thiotepa, busulfan, and cyclophosphamide. Grafts were T-cell depleted. All evaluable patients engrafted. Five died of transplant complications. The cumulative incidence of graft-versus host disease was 6%. No patient had recurrence of disease. Five-year overall survival was 77%. Age at transplant <6 years was strongly associated with better survival. Based on these results, transplant with chemotherapy-only cytoreductive regimens and T-cell-depleted stem cell transplants could be recommended for patients with high-risk NMHD, especially at a younger age. PMID- 27715386 TI - BECN1/Beclin 1 sorts cell-surface APP/amyloid beta precursor protein for lysosomal degradation. AB - The regulation of plasma membrane (PM)-localized transmembrane protein/receptor trafficking has critical implications for cell signaling, metabolism and survival. In this study, we investigated the role of BECN1 (Beclin 1) in the degradative trafficking of PM-associated APP (amyloid beta precursor protein), whose metabolism to amyloid-beta, an essential event in Alzheimer disease, is dependent on divergent PM trafficking pathways. We report a novel interaction between PM-associated APP and BECN1 that recruits macroautophagy/endosomal regulatory proteins PIK3C3 and UVRAG. We found that BECN1 promotes surface APP internalization and sorting predominantly to endosomes and endolysosomes. BECN1 also promotes the targeting of a smaller fraction of internalized APP to LC3 positive phagophores, suggesting a role for BECN1-dependent PM macroautophagy in APP degradation. Furthermore, BECN1 facilitates lysosomal degradation of surface APP and reduces the secretion of APP metabolites (soluble ectodomains, sAPP). The association between APP and BECN1 is dependent on the evolutionarily conserved domain (ECD) of BECN1 (amino acids 267-337). Deletion of a BECN1 ECD subregion (amino acids 285-299) did not impair BECN1- PIK3C3 interaction, PtdIns3K function or macroautophagy, but was sufficient to impair the APP-BECN1 interaction and BECN1's effects on surface APP internalization and degradation, resulting in increased secretion of sAPPs. Interestingly, both the BECN1-APP association and BECN1-dependent APP endocytosis and degradative trafficking were negatively regulated by active AKT. Our results further implicate phosphorylation of the BECN1 Ser295 residue in the inhibition of APP degradation by AKT. Our studies reveal a novel function for BECN1 in the sorting of a plasma membrane protein for endolysosomal and macroautophagic degradation. PMID- 27715385 TI - Progress of endocytic CHRN to autophagic degradation is regulated by RAB5-GTPase and T145 phosphorylation of SH3GLB1 at mouse neuromuscular junctions in vivo. AB - Endocytosed nicotinic acetylcholine receptors (CHRN) are degraded via macroautophagy/autophagy during atrophic conditions and are accompanied by the autophagic regulator protein SH3GLB1. The present study addressed the functional role of SH3GLB1 on CHRN trafficking and its implementation. We found an augmented ratio of total SH3GLB1 to threonine-145 phosphorylated SH3GLB1 (SH3GLB1:p SH3GLB1) under conditions of increased CHRN vesicle numbers. Overexpression of T145 phosphomimetic (T145E) and phosphodeficient (T145A) mutants of SH3GLB1, was found to either slow down or augment the processing of endocytic CHRN vesicles, respectively. Co-expression of the early endosomal orchestrator RAB5 largely rescued the slow processing of endocytic CHRN vesicles induced by T145E. SH3GLB1 phosphomutants did not modulate the expression or colocalization of RAB5 with CHRN vesicles, but instead altered the expression of RAB5 activity regulators. In summary, these findings suggest that SH3GLB1 controls CHRN endocytic trafficking in a phosphorylation- and RAB5-dependent manner at steps upstream of autophagosome formation. PMID- 27715387 TI - Targeting neuronal MAPK14/p38alpha activity to modulate autophagy in the Alzheimer disease brain. AB - Dysregulated autophagic-lysosomal degradation of proteins has been linked to the most common genetic defect in familial Alzheimer disease, and has been correlated with disease progression in both human disease and in animal models. Recently, it was demonstrated that the expression of MAPK14/p38alpha protein is upregulated in the brain of APP-PS1 transgenic Alzheimer mouse and further that genetic deficiency of Mapk14 in the APP-PS1 mouse stimulates macroautophagy/autophagy, which then leads to reduced amyloid pathology via increasing autophagic-lysosomal degradation of BACE1. The findings resolve at least in the context of the APP-PS1 mouse, prior conflicting in vitro observations that have implicated MAPK14 in autophagic processes, and indicate that inhibition of MAPK14 enzyme activity has potential as a therapeutic approach to mitigate a critical physiological defect within neurons of the Alzheimer disease brain. Moreover, the findings suggest that biomarkers of BACE1 activity could be utilized to evaluate the effects of MAPK14 inhibition and other autophagy-inducing therapeutic approaches in human clinical studies, thereby potentially facilitating the clinical development of such agents. PMID- 27715388 TI - Medical Malpractice in Uveitis: A Review of Clinical Entities and Outcomes. AB - PURPOSE: To guide risk management in uveitis. METHODS: Retrospective review of malpractice verdicts, rulings, and settlements. RESULTS: The WestLaw(r) database was reviewed for lawsuits related to uveitis in the United States from 1930-2014. Twenty-five cases met inclusion criteria, and 48% of these were infectious. Overall, 64% of outcomes favored the defendant ophthalmologist. The most common diagnoses were viral retinitis (28%), iritis (12%), syphilis (8%), and toxoplasmosis (8%). Seven suits (28%) were resolved by settlement, with mean adjusted indemnities of $724,302 (median, $409,390; range, $127,837-2,021,887). Two cases (8%) resulted in plaintiff verdict, with adjusted awards of $1,399,800 and $630,799. CONCLUSIONS: Despite being a rare diagnosis, viral retinitis (especially acute retinal necrosis) is the most common clinical entity associated with litigation in uveitis and should be considered early. Educating patients about potential adverse events, early testing for syphilis, and maintaining a positive relationship may also minimize risk. PMID- 27715389 TI - Cell adhesion to anosmin via alpha5beta1, alpha4beta1, and alpha9beta1 integrins. AB - Anosmin is an extracellular matrix protein, and genetic defects in anosmin result in human Kallmann syndrome. It functions in neural crest formation, cell adhesion, and neuronal migration. Anosmin consists of multiple domains, and it has been reported to bind heparan sulfate, FGF receptor, and UPA. In this study, we establish cell adhesion/spreading assays for anosmin and use them for antibody inhibition analyses to search for an integrin adhesion receptor. We find that alpha5beta1, alpha4beta1, and alpha9beta1 integrins are needed for effective adhesive receptor function in cell adhesion and cell spreading on anosmin; adhesion is inhibited by both RGD and alpha4beta1 CS1-based peptides. This identification of anosmin-integrin adhesion receptors should facilitate studies of anosmin function in cell and developmental biology. PMID- 27715390 TI - Mice deficient in the Vici syndrome gene Epg5 exhibit features of retinitis pigmentosa. AB - Autophagy helps to maintain cellular homeostasis by removing misfolded proteins and damaged organelles, and generally acts as a cytoprotective mechanism for neuronal survival. Here we showed that mice deficient in the Vici syndrome gene Epg5, which is required for autophagosome maturation, show accumulation of ubiquitin-positive inclusions and SQSTM1 aggregates in various retinal cell types. In epg5-/- retinas, photoreceptor function is greatly impaired, and degenerative features including progressively reduced numbers of photoreceptor cells and increased numbers of apoptotic cells in the outer nuclear layer are observed, while the morphology of other parts of the retina is not severely affected. Downstream targets of the unfolded protein response (UPR), including the death inducer DDIT3/CHOP, and also levels of cleaved CASP3 (caspase 3), are elevated in epg5-/- retinas. Thus, apoptotic photoreceptor cell death in epg5-/- retinas may result from the elevated UPR. Our results reveal that Epg5-deficient mice recapitulate key characteristics of retinitis pigmentosa and thus may provide a valuable model for investigating the molecular mechanism of photoreceptor degeneration. PMID- 27715391 TI - Regulation of lysosomal phosphoinositide balance by INPP5E is essential for autophagosome-lysosome fusion. AB - Macroautophagy (autophagy) is a multistep intracellular degradation system. Autophagosomes form, mature, and ultimately fuse with lysosomes, where their sequestered cargo molecules are digested. In contrast to autophagosome formation, our knowledge of autophagosome-lysosome fusion is limited. In a recent study, we identified a novel regulator of autophagy, INPP5E (inositol polyphosphate-5 phosphatase E), which is essential for autophagosome-lysosome fusion. INPP5E primarily functions in neuronal cells, and knockdown of the corresponding gene causes accumulation of autophagosomes by impairing fusion with lysosomes. Some INPP5E molecules localize at the lysosome, and both lysosomal localization and INPP5E enzymatic activity are crucial for autophagy. In addition, INPP5E decreases PtdIns(3,5)P2 levels on lysosomes, leading to activation of CTTN (cortactin) and stabilization of actin filaments, which are also essential for autophagosome-lysosome fusion. Mutations in INPP5E are causative for Joubert syndrome, a rare brain abnormality, and our results indicate that defects in autophagy play a critical role in pathogenesis. PMID- 27715392 TI - Contribution of semaphorins to the formation of the peripheral nervous system in higher vertebrates. AB - Semaphorins are a large family of proteins characterized by sema domains and play a key role not only in the formation of neural circuits, but in the immune system, angiogenesis, tumor progression, and bone metabolism. To date, 15 semaphorins have been reported to be involved in the formation of the peripheral nervous system (PNS) in higher vertebrates. A number of experiments have revealed their functions in the PNS, where they act mainly as axonal guidance cues (as repellents or attractants). Semaphorins also play an important role in the migration of neurons and formation of sensory-motor connections in the PNS. This review summarizes recent knowledge regarding the functions of higher vertebrate semaphorins in the formation of the PNS. PMID- 27715393 TI - Expression of kindlin-3 in melanoma cells impedes cell migration and metastasis. AB - Kindlins are a small family of 4.1-ezrin-radixin-moesin (FERM)-containing cytoplasmic proteins. Kindlin-3 is expressed in platelets, hematopoietic cells, and endothelial cells. Kindlin-3 promotes integrin activation, clustering and outside-in signaling. Aberrant expression of kindlin-3 was reported in melanoma and breast cancer. Intriguingly, kindlin-3 has been reported to either positively or negatively regulate cancer cell metastasis. In this study, we sought to clarify the expression of kindlin-3 in melanoma cells and its role in melanoma metastasis. Two widely used metastatic mouse and human melanoma cell lines B16 F10 and M10, respectively, were examined and found to lack kindlin-3 mRNA and protein expression. When kindlin-3 was ectopically expressed in these cells, cell migration was markedly reduced. These are attributed to aberrant Rac1 and RhoA activation and overt membrane ruffling. Our data demonstrate for the first time that despite its well established role as a positive regulator of integrin mediated cell adhesion, aberrant expression of kindlin-3 could lead to imbalanced RhoGTPases signaling that impedes rather than promotes cell migration. PMID- 27715394 TI - Orphan G protein-coupled receptor GPRC5A modulates integrin beta1-mediated epithelial cell adhesion. AB - G-Protein Coupled Receptor (GPCR), Class C, Group 5, Member A (GPRC5A) has been implicated in several malignancies. The underlying mechanisms, however, remain poorly understood. Using a panel of human cell lines, we demonstrate that CRISPR/Cas9-mediated knockout and RNAi-mediated depletion of GPRC5A impairs cell adhesion to integrin substrates: collagens I and IV, fibronectin, as well as to extracellular matrix proteins derived from the Engelbreth-Holm-Swarm (EHS) mouse sarcoma (Matrigel). Consistent with the phenotype, knock-out of GPRC5A correlated with a reduced integrin beta1 (ITGB1) protein expression, impaired phosphorylation of the focal adhesion kinase (FAK), and lower activity of small GTPases RhoA and Rac1. Furthermore, we provide the first evidence for a direct interaction between GPRC5A and a receptor tyrosine kinase EphA2, an upstream regulator of FAK, although its contribution to the observed adhesion phenotype is unclear. Our findings reveal an unprecedented role for GPRC5A in regulation of the ITGB1-mediated cell adhesion and it's downstream signaling, thus indicating a potential novel role for GPRC5A in human epithelial cancers.

PMID- 27715397 TI - Depletion of JMJD5 sensitizes tumor cells to microtubule-destabilizing agents by altering microtubule stability. AB - Microtubules play essential roles in mitosis, cell migration, and intracellular trafficking. Drugs that target microtubules have demonstrated great clinical success in cancer treatment due to their capacity to impair microtubule dynamics in both mitotic and interphase stages. In a previous report, we demonstrated that JMJD5 associated with mitotic spindle and was required for proper mitosis. However, it remains elusive whether JMJD5 could regulate the stability of cytoskeletal microtubules and whether it affects the efficacy of microtubule targeting agents. In this study, we find that JMJD5 localizes not only to the nucleus, a fraction of it also localizes to the cytoplasm. JMJD5 depletion decreases the acetylation and detyrosination of alpha-tubulin, both of which are markers of microtubule stability. In addition, microtubules in JMJD5-depleted cells are more sensitive to nocodazole-induced depolymerization, whereas JMJD5 overexpression increases alpha-tubulin detyrosination and enhances the resistance of microtubules to nocodazole. Mechanistic studies revealed that JMJD5 regulates MAP1B protein levels and that MAP1B overexpression rescued the microtubule destabilization induced by JMJD5 depletion. Furthermore, JMJD5 depletion significantly promoted apoptosis in cancer cells treated with the microtubule targeting anti-cancer drugs vinblastine or colchicine. Together, these findings suggest that JMJD5 is required to regulate the stability of cytoskeletal microtubules and that JMJD5 depletion increases the susceptibility of cancer cells to microtubule-destabilizing agents. PMID- 27715398 TI - Survivin is a guardian of the intestinal stem cell niche and its expression is regulated by TGF-beta. AB - As an inhibitor of apoptosis (IAP) family member, Survivin is known for its role during regulation of apoptosis. More recently its function as a cell cycle regulator has become evident. Survivin was shown to play a pivotal role during embryonic development and is highly expressed in regenerative tissue as well as in many cancer types. We examined the function of Survivin during mouse intestinal organogenesis and in gut pathophysiology. We found high expression of Survivin in experimentally induced colon cancer in mice but also in colon tumors of humans. Moreover, Survivin was regulated by TGF-beta and was found to be highly expressed during mucosal healing following intestinal inflammation. We identified that expression of Survivin is essential early on in life, as specific deletion of Survivin in Villin expressing cells led to embryonic death around day 12 post coitum. Together with our recent study on the role of Survivin in the gut of adult mice our data demonstrate that Survivin is an essential guardian of embryonic gut development and adult gut homeostasis protecting the epithelium from cell death promoting the proliferation of intestinal stem and progenitor cells. PMID- 27715396 TI - Understanding force-generating microtubule systems through in vitro reconstitution. AB - Microtubules switch between growing and shrinking states, a feature known as dynamic instability. The biochemical parameters underlying dynamic instability are modulated by a wide variety of microtubule-associated proteins that enable the strict control of microtubule dynamics in cells. The forces generated by controlled growth and shrinkage of microtubules drive a large range of processes, including organelle positioning, mitotic spindle assembly, and chromosome segregation. In the past decade, our understanding of microtubule dynamics and microtubule force generation has progressed significantly. Here, we review the microtubule-intrinsic process of dynamic instability, the effect of external factors on this process, and how the resulting forces act on various biological systems. Recently, reconstitution-based approaches have strongly benefited from extensive biochemical and biophysical characterization of individual components that are involved in regulating or transmitting microtubule-driven forces. We will focus on the current state of reconstituting increasingly complex biological systems and provide new directions for future developments. PMID- 27715400 TI - Genetic Variation in the 11beta-hydroxysteroid-dehydrogenase 1 Gene Determines NAFLD and Visceral Obesity. AB - CONTEXT/OBJECTIVE: Acute pharmacological inhibition of 11beta-hydroxysteroid dehydrogenase 1 (11beta-HSD1), which converts cortisone into the much more potent cortisol in peripheral tissues, results in reduction of total, visceral, and liver fat but not insulin resistance. We now investigated whether lifelong alterations of 11beta-HSD1 activity similarly affect these cardiometabolic risk parameters by studying single-nucleotide polymorphisms (SNPs) in the 11beta-HSD1 coding gene (HSD11B1). DESIGN/METHODS: Liver fat content was measured by 1H magnetic resonance spectroscopy and total and visceral fat mass by 1H-magnetic resonance tomography in 327 subjects. Insulin sensitivity (IS) was estimated during an oral glucose tolerance test and the euglycemic, hyperinsulinemic clamp (n = 219). Nine SNPs covering the whole HSD11B1 gene were genotyped. RESULTS: After correction for multiple testing, liver fat content strongly correlated with three SNPs, rs2235543, rs12565406, and rs4844880 (P = .0002, P = .001, and P = .0009, respectively), independently of gender and age. There was a nominal association of these SNPs with hepatic IS but only of rs4844880 with whole-body IS. Subjects homozygous for the major allele had an adjusted odds ratio of 2.16 (95% confidence interval [CI] 1.23-3.90) for rs2235543, 2.06 (95% CI 1.08-4.13) for rs12565406, and 1.95 (95% CI 1.13-3.49) for rs4844880 for having nonalcoholic fatty liver disease compared with carriers of the minor allele. Less strong associations of these SNPs with visceral fat mass were observed. In liver biopsies, carriers of the minor alleles of rs2235543 and rs12565406 had significantly lower HSD11B1 mRNA expression (n = 105, P = .034 and P = .0086, respectively). CONCLUSIONS: 11beta-HSD1 may be an important enzyme in the pathogenesis of fatty liver and visceral obesity and a promising target for their treatment. PMID- 27715399 TI - Proteolytic fragments of fibronectin function as matrikines driving the chemotactic affinity of prostate cancer cells to human bone marrow mesenchymal stromal cells via the alpha5beta1 integrin. AB - : The haematopoietic niche is contributed to by bone marrow-resident mesenchymal stromal cells (BM-MSCs) and subverted by prostate cancer cells. To study mechanisms by which BM-MSCs and prostate cancer cells may interact, we assessed the migration, invasion, adhesion and proliferation of bone-derived prostate cancer cells (PC-3) in co-culture with pluripotent human BM-MSCs. We observed a strong adhesive, migratory and invasive phenotype of PC-3 cells with BM- MSC-co culture and set out to isolate and characterize the bioactive principle. Initial studies indicated that chemotaxis was secondary to a protein residing in the >100kDa fraction. Size-exclusion chromatography (SEC) recovered peak activity in a high-molecular weight fraction containing thrombospondin-1 (TSP1). While TSP1 immunodepletion decreased activity, put-back with purified TSP1 did not reproduce bioactivity. Further purification of the TSP1-containing high-molecular weight fraction of the BM-MSC secretome with heparin-affinity chromatography recovered bioactivity with highly restricted bands on polyacrylamide gel electrophoresis, determined by mass spectroscopy to be proteolytic fragments of fibronectin (FN). Put-back experiments with full-length FN permitted adhesion but failed to induce migration. Monospecific antibodies to FN blocked adhesion. Proteolytic cleavage of FN generated FN fragments which now induced migration. Neutralizing monoclonal antibodies to FN receptors alpha5 and beta1 integrins, and alpha5 knockdown specifically blocked migration and adhesion. CONCLUSION: Fibronectin fragments (FNFr) function as matrikines driving the chemotactic affinity of prostate cancer cells via the alpha5beta1 integrin. Taken together with the high-frequency of alpha5beta1 expression in disseminated prostate cancer cells in bone marrow aspirates from patients, the FNFr/FN-alpha5beta1 interaction warrants further study as a therapeutic target. PMID- 27715401 TI - Comparison of Early (2 Days) and Later (28 Days) Response of Adipose Tissue to Very Low-Calorie Diet in Obese Women. AB - CONTEXT: Beneficial metabolic effects of calorie restriction found in the early stage of hypocalorie diets may be caused by the modulation of metabolic and endocrine function of adipose tissue. OBJECTIVE: The objective of the study was to compare metabolic and inflammation-related characteristics of sc adipose tissue (SAAT) in the early (2 d) and later (28 d) phase of a very low calorie diet (VLCD). Design, Setting, Intervention, and Patients: Seventeen moderately obese premenopausal women followed an 800 kcal/d VLCD for 28 days. Anthropometric measurements, blood sampling, and a biopsy of SAAT were performed before the diet and after 2 and 28 days of the VLCD. MAIN OUTCOME MEASURE(S): mRNA expression of 50 genes related to lipid metabolism, inflammation, and fibrosis were analyzed in SAAT. Secretion of adipokines was determined in SAAT explants and adipokines, fibroblast growth factor 21 (FGF21) and C-reactive protein were measured in plasma. RESULTS: In the early phase of the VLCD, the expression of lipolytic genes was increased, whereas the expression of lipogenic genes was significantly suppressed. The inflammatory markers in SAAT remained unchanged. At the later phase, expression of genes involved in lipogenesis and beta-oxidation was markedly suppressed, whereas the expression of inflammatory markers was increased. The changes of lipogenic genes after 28 days of the VLCD correlated with FGF21 changes. CONCLUSION: The early and later phases of a VLCD differ with respect to metabolic and inflammatory responses in SAAT. The expression changes in SAAT in the early phase of the VLCD could not explain the effect of short calorie restriction on the improvement of insulin sensitivity. An interplay of SAAT with liver function during VLCD mediated by FGF21 might be suggested. PMID- 27715402 TI - Effects of Cyclin Dependent Kinase 9 inhibition on zebrafish larvae. AB - CDK9 is a known regulator of cellular transcription, growth and proliferation. Small molecule inhibitors are currently being developed and assessed in clinical trials as anti-cancer drugs. The zebrafish embryo provides an ideal model to explore the effects of CDK9 inhibition in-vivo. This has not been adequately explored previously at the level of a whole organism. We have compared and contrasted the effects of pharmacological and molecular inhibition of CDK9 on somatic growth, apoptosis and cellular proliferation in zebrafish larvae between 0 to 120 hours post fertilisation (hpf) using flavopiridol, a selective CDK9 antagonist, and CDK9-targeting morpholino. We demonstrate that the inhibition of CDK9 diminishes cellular proliferation and increases apoptosis. Subsequently, it affects somatic growth and development of a number of key embryonic structures including the brain, heart, eye and blood vessels. For the first time, we have localized CDK9 at a subcellular level in whole-mounted larvae. This works shows, at a high-throughput level, that CDK9 clearly plays a fundamental role in early cellular growth and proliferation. PMID- 27715403 TI - Vitamin D decreases STAT phosphorylation and inflammatory cytokine output in T LGL leukemia. AB - Large granular lymphocyte leukemia (LGLL) is a rare incurable chronic disease typically characterized by clonal expansion of CD3+ cytotoxic T-cells. Two signal transducer and activator of transcription factors, STAT1 and STAT3, are constitutively active in T-LGLL. Disruption of this activation induces apoptosis in T-LGLL cells. Therefore, considerable efforts are focused on developing treatments that inhibit STAT activation. Calcitriol, the active form of vitamin D, has been shown to decrease STAT1 and STAT3 phosphorylation in cancer cell lines and autoimmune disease mouse models. Thus, we investigated whether calcitriol could be a valid therapeutic for T-LGLL. Calcitriol treatment of the TL-1 cell line (model of T-LGLL) led to decreased phospho-Y701 STAT1 and phospho Y705 STAT3 and increased vitamin D receptor (VDR) levels. Doses of 10 and 100 nM calcitriol also significantly decreased the inflammatory cytokine IFN-gamma in the TL-1 cell line. The overall cell viability did not change when the TL-1 cell line was treated with 0.1 to 1000 nM calcitriol. Studies with primary T-LGLL patient peripheral blood mononuclear cells showed that the majority of T-LGLL patients have detectable VDR and activated STATs in contrast to normal donor controls. Treatment of primary T-LGLL patient cells with calcitriol recapitulated findings from the TL-1 cell line. Overall, our results suggest that calcitriol may reprogram T-cells to decrease essential STAT activation and pro-inflammatory cytokine output. These data support further investigation into calcitriol as an experimental therapeutic for T-LGLL. PMID- 27715404 TI - Severe pediatric Graves orbitopathy in adolescents of African origin. AB - This article reports on two cases of severe pediatric Graves orbitopathy (GO) in two adolescents of African origin. Two black male adolescents presented with highly active GO and signs of beginning compressive optic neuropathy. Neither of them were smokers nor had a family history of GO. Besides urgent referral to pediatric endocrinologists, intravenous methylprednisolon pulse therapy was initiated. In spite of the fluctuating thyroid hormone levels in the initial phase of antithyroid therapy, intravenous steroid administration stopped the progression of malignant GO rapidly in both of our patients without any considerable side effects. Although the course of GO during childhood is considered to be mild, severe, sight threatening GO-requiring immunosuppression may occur at young age, as in the reported adolescent patients of African descent. PMID- 27715406 TI - Generalization and maintenance of a self-management program for drooling in children with neurodevelopmental disabilities: A second case series. AB - In this case series (n = 10) with a non-concurrent multiple baseline design, a self-management program was shown to be effective during inpatient training in eight participants with oral-motor problems and normal intelligence or mild intellectual disabilities. They were taught to perform a self-management routine and to remain dry for increasing time intervals. In addition, the program provided differential (self-) reinforcement of swallowing, controlling and wiping behavior, explicit formulation of motivational factors, instruction and feedback for parents and teachers, and continued practice after discharge. Generalization of the initial effect to the school setting was demonstrated in seven participants. Follow-up assessments demonstrated maintenance of positive results in four children up to 24 weeks, and for two other participants until 6 weeks after discharge. These results appeared to be relevant to parents and teachers. Teaching parents and teachers to implement the procedure enables them to support the child without professional supervision in the case of relapse.

PMID- 27715405 TI - Autophagy in Dictyostelium: Mechanisms, regulation and disease in a simple biomedical model. AB - Autophagy is a fast-moving field with an enormous impact on human health and disease. Understanding the complexity of the mechanism and regulation of this process often benefits from the use of simple experimental models such as the social amoeba Dictyostelium discoideum. Since the publication of the first review describing the potential of D. discoideum in autophagy, significant advances have been made that demonstrate both the experimental advantages and interest in using this model. Since our previous review, research in D. discoideum has shed light on the mechanisms that regulate autophagosome formation and contributed significantly to the study of autophagy-related pathologies. Here, we review these advances, as well as the current techniques to monitor autophagy in D. discoideum. The comprehensive bioinformatics search of autophagic proteins that was a substantial part of the previous review has not been revisited here except for those aspects that challenged previous predictions such as the composition of the Atg1 complex. In recent years our understanding of, and ability to investigate, autophagy in D. discoideum has evolved significantly and will surely enable and accelerate future research using this model. PMID- 27715409 TI - Community pharmacies as sites of adult vaccination: A systematic review. AB - Vaccine-preventable deaths among adults remain a major public health concern, despite continued efforts to increase vaccination rates in this population. Alternative approaches to immunization delivery may help address under vaccination among adults. This systematic review assesses the feasibility, acceptability, and effectiveness of community pharmacies as sites for adult vaccination. We searched 5 electronic databases (PubMed, EMBASE, Scopus, Cochrane, LILACS) for studies published prior to June 2016 and identified 47 relevant articles. We found that pharmacy-based immunization services (PBIS) have been facilitated by state regulatory changes and training programs that allow pharmacists to directly provide vaccinations. These services are widely accepted by both patients and pharmacy staff, and are capable of improving access and increasing vaccination rates. However, political and organizational barriers limit the feasibility and effectiveness of vaccine delivery in pharmacies. These studies provide evidence to inform policy and organizational efforts that promote the efficacy and sustainability of PBIS. PMID- 27715411 TI - The impact of autophagy on the development of senescence in primary tubular epithelial cells. AB - Autophagy and senescence are 2 distinct pathways that are importantly involved in acute kidney injury and renal repair. Recent data indicate that the 2 processes might be interrelated. To investigate the potential link between autophagy and senescence in the kidney we isolated primary tubular epithelial cells (PTEC) from wild-type mice and monitored the occurrence of cellular senescence during autophagy activation and inhibition. We found that the process of cell isolation and transfer into culture was associated with a strong basal autophagic activation in PTEC. Specific inhibition of autophagy by silencing autophagy related 5 (Atg5) counteracted the occurrence of senescence hallmarks under baseline conditions. Reduced senescent features were also observed in Atg5 silenced PTEC after gamma-irradiation and during H-Ras induced oncogenic senescence, but the response was less uniform in these stress models. Senescence inhibition was paralleled by better preservation of a mature epithelial phenotype in PTEC. Interestingly, treatment with rapamycin, which acts as an activator of autophagy, also counteracted the occurrence of senescence features in PTEC. While we interpret the anti-senescent effect of rapamycin as an autophagy-independent effect of mTOR-inhibition, the more specific approach of Atg5 silencing indicates that overactivated autophagy can have pro-senescent effects in PTEC. These results highlight the complex interaction between cell culture dependent stress mechanisms, autophagy and senescence. PMID- 27715412 TI - Bucrates lanista Rehn 1918 (Tettigoniidae: Conocephalinae): The First Record from the Brazilian Pantanal, the First Description of the Male, the First Karyotypic Report for the Genus, and the First Telomeric Hybridization of the Subfamily. AB - Bucrates lanista, the most southerly distributed species in the genus Bucrates Burmeister, was originally described from Brazil based on a female collected in the state of Rio Grande do Sul, but the species has not been recorded since 1918. In this work, we report that B. lanista inhabits the Pantanal Wetland in the state of Mato Grosso do Sul and, for the first time, describe the male. Individuals of B. lanista are gregarious and present a brown/green color dimorphism; this behavior and color variation are also observed in species of closely related genera. Individuals from the Pantanal vary slightly from those of Rio Grande do Sul. The karyotype was determined to be 2n? = 21 = 20 + X0 and 2n? = 22 = 20 + XX. The X chromosome is metacentric and the largest of the complement, and all of the autosomes are submetacentrics. All chromosomes solely present telomeric (TTAGG)n repeats at their ends, and some chromosomes present positive and negative DAPI bands. PMID- 27715413 TI - Complete Mitochondrial Reveals a New Phylogenetic Perspective on the Brackish Water Goby Mugilogobius Group (Teleostei: Gobiidae: Gobionellinae). AB - The Mugilogobius group consists of brackish water gobionellines widely distributed in the Indo-West Pacific region. Complete mitochondrial genome and morphological evidence was collected to estimate their phylogenetic relationship and taxonomic status. A total of 11 genera were sampled, including Brachygobius, Calamiana, Hemigobius, Mugilogobius, Pandaka, Pseudogobiopsis, Pseudogobius, Redigobius, Rhinogobius, Stigmatogobius, and Wuhanlinigobius, five of which were sequenced for the first time. A morphological phylogenetic tree was also reconstructed based on 35 characters. The molecular phylogenetic trees reveal that the Mugilogobius group contains four major clades. The present study also reveals that the adult male mouth size and forked sensory papillae row d can be considered as synapomorphies, and that the head pores on inter-orbital, anterior oculoscapular, and preopercular regions can be regarded as derived features among the Mugilogobius group. Furthermore, the absence of posterior oculoscapular pores may provide a clue for understanding the evolutionary history of the Mugilogobius group. PMID- 27715414 TI - Distribution of Dall's Porpoise, Phocoenoides dalli, in the North Pacific and Bering Sea, Based on T/S Oshoro Maru 2012 Summer Cruise Data. AB - Dall's porpoise (Phocoenoides dalli) is a small toothed cetacean, widely inhabiting the North Pacific Ocean and adjacent seas, between about 30 and 62 degrees N; however, only limited studies of its ecology have been made in nearshore areas. A cetacean sighting survey lasting 60 days was conducted during the 2012 summer cruise of the T/S Oshoro Maru (Hokkaido University, Japan) in the North Pacific Ocean and Bering Sea. Based on this data, the distribution of Dall's porpoises and the factors controlling it in the pelagic habitat were investigated. A total of 808 individual Dall's porpoises in 166 groups were sighted during a total of 469.6 hr and 4946.6 nm observations. The cruise consisted of three legs and the average porpoise group size was significantly larger in Leg 1. The sightings were concentrated at water depths of less than 1000 m and near eastern Aleutian passes. Sighting clusters were found on the 200 m isobath of the southeastern Bering Sea continental slope. There was a peak in sightings where the sea surface temperature (SST) was relatively cold, between 5 and 7 degrees C. Although similar track routes were taken in Leg 1 and Leg 3, the number of sightings per unit effort was larger in Leg 1. This difference may have arisen from the significant rise in SST as the season progressed. Relatively large group size found in this study might relate with prey abundance along the Aleutian Islands. PMID- 27715415 TI - Fine-Scale Genetic Differentiation in a Salamander Hynobius tokyoensis Living in Fragmented Urban Habitats in and Around Tokyo, Japan. AB - Salamanders are expected to differentiate genetically among local populations due to their low dispersal ability, and are potentially susceptible to loss of genetic diversity if the population is isolated by habitat fragmentation. The salamander Hynobius tokyoensis is a lowland lentic breeder and endemic to a narrow area of central Japan. In this urban area, H. tokyoensis habitats are extensively fragmented and several populations are threatened with extinction, but information on genetic divergence and loss of genetic diversity is scarce. We performed mitochondrial (cyt b) and microsatellite (five loci) DNA analyses of 815 individuals from 46 populations in 12 regions across their entire distribution range. As a result, populations were clearly separated into northern and southern groups, and genetic differentiation among the 12 regions was also evident. Regional differentiation appears to be affected by a complex geographical history, but the genetic diversity of each population may have also been affected by recent habitat fragmentation. There were positive correlations between the mitochondrial and microsatellite DNA diversities. Some populations have lost genetic diversity in both mitochondrial and microsatellite DNAs; all such populations were at the peripheral edges of the species distribution range. Thus, even in attempts to restore genetic diversity in a small population by the transfer of outside individuals, efforts must be made to avoid genetic pollution. PMID- 27715410 TI - KSHV reduces autophagy in THP-1 cells and in differentiating monocytes by decreasing CAST/calpastatin and ATG5 expression. AB - We have previously shown that Kaposi sarcoma-associated herpesvirus (KSHV) impairs monocyte differentiation into dendritic cells (DCs). Macroautophagy/autophagy has been reported to be essential in such a differentiating process. Here we extended these studies and found that the impairment of DC formation by KSHV occurs through autophagy inhibition. KSHV indeed reduces CAST (calpastatin) and consequently decreases ATG5 expression in both THP-1 monocytoid cells and primary monocytes. We unveiled a new mechanism put in place by KSHV to escape from immune control. The discovery of viral immune suppressive strategies that contribute to the onset and progression of viral associated malignancies is of fundamental importance for finding new therapeutic approaches against them. PMID- 27715417 TI - A Natural Population Derived from Species Hybridizationin the Drosophila ananassae Species Complexon Penang Island, Malaysia. AB - We surveyed natural population of the Drosophila ananassae species complex on Penang Island, Malaysia. Analyses of phenotypic traits, chromosome arrangements, molecular markers, and reproductive isolation suggest the existence of two species: D. ananassae and D. cf. parapallidosa. Molecular marker analysis indicates that D. cf. parapallidosa carries chromosome Y and 4 introgressions from D. ananassae. Thus, D. cf. parapallidosa seems to be a hybrid descendant that recently originated from a natural D. parapallidosa?* D. ananassae? cross. Furthermore, D. cf. parapallidosa behaves differently from authentic D. parapallidosa with respect to its reproductive isolation from D. ananassae. Premating isolation is usually seen in only the D. ananassae?* D. parapallidosa? cross, but we observed it in crosses of both directions between D. ananassae and D. cf. parapallidosa. In addition, hybrid males from the D. ananassae?* D. parapallidosa? cross are usually sterile, but they were fertile when D. ananassae? were mated with D. cf. parapallidosa ?. We attempted an artificial reconstruction of the hybrid species to simulate the evolutionary process(es) that produced D. cf. parapallidosa. This is a rare case of natural hybrid population in Drosophila and may be a useful system for elucidating speciation with gene flow. PMID- 27715416 TI - Hematophagous Flies Attracted to Frog Calls in a Preserved Seasonal Forest of the Austral Neotropics, with a Description of a New Species of Corethrella (Diptera: Corethrellidae). AB - The signaler-eavesdropper interaction has been investigated for a wide range of organisms, and although many flies feed on calling frogs, this dynamic has been addressed only poorly in the austral Neotropics. We investigated this interaction in southern Brazil using pairs of suction traps (acoustic + silent) broadcasting frog calls or an artificial white noise in ponds and streams. From 139 sessions, flies of the genera Corethrella (Corethrellidae), Forcipomyia (Ceratopogonidae) and Uranotaenia (Culicidae) were collected, including five Corethrella species, the most abundant of which was previously unknown and is formally described here. Additionally, we present the southernmost records of Corethrella lopesi, C. alticola and C. atricornis. Numbers of Forcipomyia midges and Uranotaenia mosquitoes did not differ between silent traps and traps broadcasting frog calls, and did not differ between white noise traps and adjacent silent traps. However, the number of female Corethrella was significantly higher in traps broadcasting calls of the pond-breeding frog P. aff. gracilis compared to adjacent silent traps; calls of this frog attracted the five Corethrella species and also collected significantly more female Corethrella than the white noise. By evaluating different taxa of flies and broadcasting different sounds, we demonstrated that Corethrella midges were attracted only to the acoustic cue of P. aff. gracilis calls, while Forcipomyia and Uranotaenia were captured in traps by chance. Our results suggest that female Corethrella feed on males of the common pond-breeding frog P. aff. gracilis in southern Brazil, and highlight the utility of frog call traps in revealing the diversity of Corethrella in the austral Neotropics.

AB - Deep-sea hydrothermal vent fields are among the most extreme habitats on Earth. Major research interests in these ecosystems have focused on the anomalous macrofauna, which are nourished by chemoautotrophic bacterial endosymbionts. In contrast, the meiofauna is largely overlooked in this chemosynthetic environment. The present study describes a new species, Thomontocypris shimanagai sp. nov. (Crustacea: Ostracoda), which was collected from the surface of colonies of neoverrucid barnacles and paralvinellid worms on the chimneys at the Myojin-sho submarine caldera. This is the first discovery of an ostracode from deep-sea hydrothermal vent environments in the western Pacific region. In addition to the species description, we discuss three aspects: 1) adaptation, 2) endemism, and 3) dispersal strategy of the hydrothermal vent ostracodes. Regarding these aspects, we conclude the following: 1) the new species may feed on sloughed-off tissues, mucus secretions, or fecal pellets of sessile organisms, rather than depend on chemoautotrophic bacteria as symbionts for energy; 2) as has been pointed out by other studies, Thomontocypris does not likely represent a vent-specific genus; however, this new species is considered to be endemic at the species level, as it has not been found outside of the type locality; and 3) this new species may have migrated from adjacent deep-sea chemosynthesis-based habitats, such as hydrothermal vents, with wood falls potentially having acted as stepping stones. PMID- 27715419 TI - Cosmopolitan or Cryptic Species? A Case Study of Capitella teleta (Annelida: Capitellidae). AB - Capitella teleta Blake et al., 2009 is an opportunistic capitellid originally described from Massachusetts (USA), but also reported from the Mediterranean, NW Atlantic, and North Pacific, including Japan. This putatively wide distribution had not been tested with DNA sequence data; intraspecific variation in morphological characters diagnostic for the species had not been assessed with specimens from non-type localities, and the species status of the Japanese population(s) was uncertain. We examined the morphology and mitochondrial COI (cytochrome c oxidase subunit I) gene sequences of Capitella specimens from two localities (Ainan and Gamo) in Japan. Specimens from Ainan and Gamo differed from C. teleta from Massachusetts in methyl-green staining pattern, shape of the genital spines, and shape of the capillary chaetae; we concluded that these characters vary intraspecifically. Species delimitation analyses of COI sequences suggested that worms from Ainan and Massachusetts represent C. teleta; these populations share a COI haplotype. The specimens from Gamo may represent a distinct species and comprise a sister group to C. teleta s. str.; we refer to the Gamo population as Capitella aff. teleta. The average Kimura 2-parameter (K2P) distance between C. teleta s. str. and C. aff. teleta was 3.7%. The COI data indicate that C. teleta actually occurs in both the NW Atlantic and NW Pacific. Given the short planktonic larval duration of C. teleta, this broad distribution may have resulted from anthropogenic dispersal.

AB - The Ryukyu wild boar (Sus scrofa riukiuanus) is an endemic, morphologically defined subspecies of the Eurasian wild boar (S. scrofa) found on five islands of the Ryukyu Archipelago (a group of small islands stretching from mainland Japan to Taiwan). Two hypothetical scenarios have been proposed regarding the origin of the current Ryukyu wild boar populations: 1) natural dispersal and 2) transportation and subsequent release by prehistoric humans. To test these two hypotheses, we compared the mitochondrial cytochrome b gene sequence (1140 base pairs) in 352 individual wild boar samples that included representatives of all five insular populations of the Ryukyu wild boar and populations of other conspecific subspecies in insular East and Southeast Asia and the Eurasian Continent. A total of 68 haplotypes were recognized, of which 12 were unique to the Ryukyu wild boar populations. The results of Bayesian phylogenetic analyses supported monophyly of the five Ryukyu populations (posterior probability value of 92), confirming the validity of the subspecies as a natural group. Coalescent analysis estimated the divergence times between the Ryukyu wild boar and the other conspecific subspecies as 144-465 thousand years ago (Kya), with a 95% HPD (highest posterior density) range of 51-837 Kya, and with no significant migration. Taking the broadly accepted date of initial human migration to the Ryukyus (no earlier than 50 Kya) into consideration, our results strongly suggest that the ancestral form of the Ryukyu wild boar first entered the Ryukyu Archipelago by natural dispersal prior to the arrival of prehistoric humans. PMID- 27715421 TI - Inheritance Pattern of Female Receptivity in Drosophila prolongata. AB - Choosiness, or female receptivity to copulation, is a critical component in female preference for a mating partner, as it functions at the final step in the mating process by determining whether she accepts copulation with a given male. In spite of its importance in the evolutionary process of male traits via sexual selection, little is known about the genetic variation and inheritance pattern of female receptivity. Drosophila prolongata shows a unique courtship behavior, leg vibration, which increases female receptivity to copulation. In the present study, we analyzed variation in female receptivity and its inheritance pattern in isofemale strains of D. prolongata using leg vibration as an index. There was a significant difference in female receptivity among the strains examined. A high receptivity phenotype was semi-dominantly expressed in F1 females of crosses between strains with low and high receptivity. Backcrossing F1 females to low receptivity strains resulted in a lower level of receptivity, suggesting that the high-receptivity phenotype is controlled by multiple genes with epistatic interactions. These results indicate a genetic basis of female receptivity, shedding light on the evolutionary process of sexual selection in D. prolongata. PMID- 27715422 TI - Molecular Cloning of Ghrelin and Characteristics of Ghrelin-Producing Cells in the Gastrointestinal Tract of the Common Marmoset (Callithrix jacchus). AB - Ghrelin was first isolated from human and rat as an endogenous ligand for the growth hormone secretagogue receptor (GHS-R). In the present study, we determined the ghrelin cDNA sequence of the common marmoset (Callithrix jacchus), a small bodied New World monkey, and investigated the distribution of ghrelin-producing cells in the gastrointestinal tract and localization profiles with somatostatin producing cells. The marmoset ghrelin cDNA coding region was 354 base pairs, and showed high homology to that in human, rhesus monkey, and mouse. Marmoset ghrelin consists of 28 amino acids, and the N-terminal region is highly conserved as found in other mammalian species. Marmoset preproghrelin and mature ghrelin have 86.3% and 92.9% homology, respectively, to their human counterparts. Quantitative RT-PCR analysis showed that marmoset ghrelin mRNA is highly expressed in the stomach, but it is not detected in other tissues of the gastrointestinal tract. In addition, a large number of ghrelin mRNA-expressing cells and ghrelin immunopositive cells were detected in the mucosal layer of the stomach, but not in the myenteric plexus. Moreover, all the ghrelin cells examined in the stomach were observed to be closed-type. Double staining showed that somatostatin immunopositive cells were not co-localized with ghrelin-producing cells; however, a subset of somatostatin-immunopositive cells is directly adjacent to ghrelin immunopositive cells. These findings suggest that the distribution of ghrelin cells in marmoset differs from that in rodents, and thus the marmoset may be a more useful model for the translational study of ghrelin in primates. In conclusion, we have clarified the expression and cell distribution of ghrelin in marmoset, which may represent a useful model in translational study. PMID- 27715423 TI - Regeneration of Murine Hair Follicles is Inhibited by Low-Dose-Rate Gamma Irradiation. AB - To determine whether the effects of low-dose-rate gamma (gamma) irradiation are identifiable in the regeneration of murine hair follicles, we irradiated whole bodies of C57BL/10JHir mice in the first telogen phase of the hair cycle with 137Cs gamma-rays. The mice were examined for effects on hair follicles, including number, morphology, and pigmentation in the second anagen phase. Effects of gamma radiation on melanocyte stem cells were also investigated by the indirect immunolabeling of tyrosinase-related protein 2 (TRP2). Irradiated skin showed a decrease in hair follicle density and the induction of curved hair follicles along with the presence of white hairs and hypopigmented hair bulbs. There was a small, but not significant, change in the number of TRP2-positive melanocyte stem cells in the hair bulge region of the irradiated skin. These results suggest that low-dose rate gamma-irradiation does not deplete melanocyte stem cells, but can damage stem cells and progenitors for both keratinocytes and melanocytes, thereby affecting the structure and pigmentation of regenerated hair follicles in the 2nd anagen phase. PMID- 27715424 TI - Population Structure of the Raccoon Dog on the Grounds of the Imperial Palace, Tokyo, Revealed by Microsatellite Analysis of Fecal DNA. AB - The raccoon dog (Nyctereutes procyonoides, Canidae, Carnivora) is highly adaptable to urban environments. Populations of carnivorans inhabiting urban areas sometimes differ ecologically and genetically from those in rural areas. However, there is little information on urban raccoon dogs. This study focused on raccoon dog populations in Tokyo, one of the most highly urbanized cities in the world. We examined the genotypes of 10 microsatellites for 101 fecal samples from raccoon dogs inhabiting the grounds of the Imperial Palace, a green space in central Tokyo. We successfully genotyped 58 samples originating from 31 individuals. We also analyzed muscle tissue samples from raccoon dogs from the grounds of the Imperial Palace, the Akasaka Imperial Grounds (a green space close to the Imperial Palace), and the surrounding urban area, and then investigated the genetic structure and diversity of these populations, and the genetic differentiation among them. The population on the grounds of the Imperial Palace was genetically differentiated from that in the Akasaka Imperial Grounds, suggesting that the roads and buildings act as barriers to gene flow. In addition, the population on the grounds of the Imperial Palace showed greater genetic difference from that in the surrounding area than that in the Akasaka Imperial Grounds. We speculate that the moats around the Imperial Palace restrict individual ranges within the palace grounds and limit migration and gene flow to other areas. PMID- 27715425 TI - Production of Knockout Mutants by CRISPR/Cas9 in the European Honeybee, Apis mellifera L. AB - The European honeybee (Apis mellifera L.) is used as a model organism in studies of the molecular and neural mechanisms underlying social behaviors and/or advanced brain functions. The entire honeybee genome has been sequenced, which has further advanced molecular biologic studies of the honeybee. Functions of genes of interest, however, remain largely to be elucidated in the honeybee due to the lack of effective reverse genetic methods. Moreover, genetically modified honeybees must be maintained under restricted laboratory conditions due to legal restrictions, further complicating the application of reverse genetics to this species. Here we applied CRISPR/Cas9 to the honeybee to develop an effective reverse genetic method. We targeted major royal jelly protein 1 (mrjp1) for genome editing, because this gene is predominantly expressed in adult workers and its mutation is not expected to affect normal development. By injecting sgRNA and Cas9 mRNA into 57 fertilized embryos collected within 3 h after oviposition, we successfully created six queens, one of which produced genome-edited male offspring. Of the 161 males produced, genotyping demonstrated that the genome was edited in 20 males. All of the processes necessary for producing these genome edited queens and males were performed in the laboratory. Therefore, we developed essential techniques to create knockout honeybees by CRISPR/Cas9. Our findings also suggested that mrjp1 is dispensable for normal male development, at least till the pupal stage. This new technology could pave the way for future functional analyses of candidate genes involved in honeybee social behaviors. PMID- 27715426 TI - Effects of Caffeine on Olfactory Learning in Crickets. AB - Caffeine is a plant-derived alkaloid that is generally known as a central nervous system (CNS) stimulant. In order to examine the effects of caffeine on higher CNS functions in insects, we used an appetitive olfactory learning paradigm for the cricket Gryllus bimaculatus. Crickets can form significant long-term memories (LTMs) after repetitive training sessions, during which they associate a conditioned stimulus (CS: odor) with an unconditioned stimulus (US: reward). Administration of hemolymphal injections of caffeine established LTM after only single-trial conditioning over a wide range of caffeine dosages (1.6 uug/kg to 39 mg/kg). We investigated the physiological mechanisms underlying this enhancement of olfactory learning performance pharmacologically, focusing on three major physiological roles of caffeine: 1) inhibition of phosphodiesterase (PDE), 2) agonism of ryanodine receptors, and 3) antagonism of adenosine receptors. Application of drugs relevant to these actions resulted in significant effects on LTM formation. These results suggest that externally applied caffeine enhances LTM formation in insect olfactory learning via multiple cellular mechanisms. PMID- 27715427 TI - Tick-borne encephalitis: What travelers should know when visiting an endemic country. AB - Tick-borne encephalitis (TBE) is an acute febrile illness with neurological manifestations that is prevalent in forested areas of moderate climate in Europe and Asia. TBE virus is transmitted by ticks and rarely by unpasteurized milk and dairy products. The disease burden is attributed mainly to resulting long-term disability, especially in individuals over 50 y of age. Currently, there is no causative treatment, but a very effective vaccination is available with a good safety profile. The vaccination requires 3 basic doses to be fully effective and regular boosters afterwards. An accelerated vaccination schedule enables a patient to reach reasonably protective titres within 3 to 4 weeks from the first injection. The risk of travel-related TBE is estimated to be less than the risk of acquiring typhoid fever while visiting highly endemic regions in South Asia, but more than the risk of acquiring Japanese encephalitis, meningococcal invasive disease, or rabies. The pre-travel risk assessment of acquiring TBE should consider known risk factors which include 1) the country and regions to be visited; 2) April to November season; 3) altitude less than 1500 m above the sea level; 4) duration of stay; 5) the extent of tick-exposure associated activities including leisure and professional outdoor activities within the endemic area; and 6) age and comorbidities of the traveler. A major challenge, however, is the very low awareness of the risk of contracting TBE in those who travel to industrialized European countries. PMID- 27715428 TI - Highlight on the dynamic organization of the nucleus. AB - The last decade has seen rapid advances in our understanding of the proteins of the nuclear envelope, which have multiple roles including positioning the nucleus, maintaining its structural organization, and in events ranging from mitosis and meiosis to chromatin positioning and gene expression. Diverse new and stimulating results relating to nuclear organization and genome function from across kingdoms were presented in a session stream entitled "Dynamic Organization of the Nucleus" at this year's Society of Experimental Biology (SEB) meeting in Brighton, UK (July 2016). This was the first session stream run by the Nuclear Dynamics Special Interest Group, which was organized by David Evans, Katja Graumann (both Oxford Brookes University, UK) and Iris Meier (Ohio State University, USA). The session featured presentations on areas relating to nuclear organization across kingdoms including the nuclear envelope, chromatin organization, and genome function.

PMID- 27715429 TI - Integration of tooth morphogenesis and innervation by local tissue interactions, signaling networks, and semaphorin 3A. AB - The tooth, like many other organs, develops from both epithelial and mesenchymal tissues, and has proven to be a valuable tool with which to investigate organ formation and peripheral innervation. Tooth formation is regulated by local epithelial-mesenchymal tissue interactions, and is closely integrated with stereotypic dental nerve navigation and patterning. Recent analyses of the function and regulation of semaphorin 3A (SEMA3A) have shed light on the regulatory mechanisms that coordinate organogenesis and innervation at the tissue and molecular levels. In the tooth, SEM3A acts as a developmentally regulated secretory chemo-repellent, that controls tooth innervation during embryonic and postnatal development. The tooth germ governs its own innervation by a combination of local tissue interactions and SEMA3A expression. SEMA3A signaling, in turn, is controlled by a number of conserved signaling effectors, including TGF-beta superfamily members, FGF, and WNT; all function in embryo and organ development, and are essential for tooth histo-morphogenesis. Thus, SEMA3A driven axon guidance is integrated into key odontogenic signaling networks, establishing this protein as a critical molecular tether between 2 distinct developmental processes (morphogenesis and sensory innervation), both of which are required to obtain a functional tooth.

PMID- 27715433 TI - Factors influencing management of unruptured intracranial aneurysms: an analysis of 424 consecutive patients. AB - OBJECTIVE The choice between treating and observing unruptured intracranial aneurysms is often difficult, with little guidance on which variables should influence decision making on a patient-by-patient basis. Here, the authors compared demographic variables, aneurysm-related variables, and comorbidities in patients who received microsurgical or endovascular treatment and those who were conservatively managed to determine which factors push the surgeon toward recommending treatment. METHODS A retrospective chart review was conducted of all patients diagnosed with an unruptured intracranial aneurysm at their institution between January 1, 2013, and January 1, 2016. These patients were dichotomized based on whether their aneurysm was treated. Demographic, geographic, socioeconomic, comorbidity, and aneurysm-related information was analyzed to assess which factors were associated with the decision to treat. RESULTS A total of 424 patients were identified, 163 who were treated surgically or endovascularly and 261 who were managed conservatively. In a multivariable model, an age < 65 years (OR 2.913, 95% CI 1.298-6.541, p = 0.010), a lower Charlson Comorbidity Index (OR 1.536, 95% CI 1.274-1.855, p < 0.001), a larger aneurysm size (OR 1.176, 95% CI 1.100-1.257, p < 0.001), multiple aneurysms (OR 2.093, 95% CI 1.121-3.907, p = 0.020), a white race (OR 2.288, 95% CI 1.245-4.204, p = 0.008), and living further from the medical center (OR 2.125, 95% CI 1.281-3.522, p = 0.003) were all associated with the decision to treat rather than observe. CONCLUSIONS Whereas several factors were expected to be considered in the decision to treat unruptured intracranial aneurysms, including age, Charlson Comorbidity Index, aneurysm size, and multiple aneurysms, other factors such as race and proximity to the medical center were unanticipated. Further studies are needed to identify such biases in patient treatment and improve treatment delineation based on patient-specific aneurysm rupture risk. PMID- 27715434 TI - Reverberation index: a novel metric by which to quantify the impact of a scientific entity on a given field. AB - The authors propose a novel bibilometric index, the reverberation index (r index), as a comparative assessment tool for use in determining differential reverberation between scientific fields for a given scientific entity. Conversely, this may allow comparison of 2 similar scientific entities within a single scientific field. This index is calculated using a relatively simple 3 step process. Briefly, Thompson Reuters' Web of Science is used to produce a citation report for a unique search parameter (this may be an author, journal article, or topical key word). From this citation report, a list of citing journals is retrieved from which a weighted ratio of citation patterns across journals can be calculated. This r-index is then used to compare the reverberation of the original search parameter across different fields of study or wherever a comparison is required. The advantage of this novel tool is its ability to transcend a specific component of the scientific process. This affords application to a diverse range of entities, including an author, a journal article, or a topical key word, for effective comparison of that entity's reverberation within a scientific arena. The authors introduce the context for and applications of the r-index, emphasizing neurosurgical topics and journals for illustration purposes. It should be kept in mind, however, that the r-index is readily applicable across all fields of study. PMID- 27715435 TI - Quantitative evaluation of vision-related and health-related quality of life after endoscopic transsphenoidal surgery for pituitary adenoma. AB - OBJECTIVE Endoscopic resection of pituitary adenomas has been reported to improve vision function in up to 80%-90% of patients with visual impairment due to these adenomas. It is unclear how these reported rates translate into improvement in visual outcomes and general health as perceived by the patients. The authors evaluated self-assessed health-related quality of life (HR-QOL) and vision related QOL (VR-QOL) in patients before and after endoscopic resection of pituitary adenomas. METHODS The authors prospectively collected data from 50 patients who underwent endoscopic resection of pituitary adenomas. This cohort included 32 patients (64%) with visual impairment preoperatively. Twenty-seven patients (54%) had pituitary dysfunction, including 17 (34%) with hormone producing tumors. Patients completed the National Eye Institute Visual Functioning Questionnaire and the 36-Item Short Form Health Survey preoperatively and 6 weeks and 6 months after surgery. RESULTS Patients with preoperative visual impairment reported a significant impact of this condition on VR-QOL preoperatively, including general vision, near activities, and peripheral vision; they also noted vision-specific impacts on mental health, role difficulties, dependency, and driving. After endoscopic resection of adenomas, patients reported improvement across all these categories 6 weeks postoperatively, and this improvement was maintained by 6 months postoperatively. Patients with preoperative pituitary dysfunction, including hormone-producing tumors, perceived their general health and physical function as poorer, with some of these patients reporting improvement in perceived general health after the endoscopic surgery. All patients noted that their ability to work or perform activities of daily living was transiently reduced 6 weeks postoperatively, followed by significant improvement by 6 months after the surgery. CONCLUSIONS Both VR-QOL and patient's perceptions of their ability to do work and perform other daily activities as a result of their physical health significantly improved by 6 months after endoscopic resection of pituitary adenoma. The use of multidimensional QOL questionnaires provides a precise assessment of perceived outcomes after endoscopic surgery. PMID- 27715436 TI - Midline and off-midline infratentorial supracerebellar approaches to the pineal gland. AB - OBJECTIVE A common approach to lesions of the pineal region is along the midline below the torcula. However, reports of how shifting the approach off midline affects the surgical exposure and relationships between the tributaries of the vein of Galen are limited. The purpose of this study is to examine the microsurgical and endoscopic anatomy of the pineal region as seen through the supracerebellar infratentorial approaches, including midline, paramedian, lateral, and far-lateral routes. METHODS The quadrigeminal cisterns of 8 formalin fixed adult cadaveric heads were dissected and examined with the aid of a surgical microscope and straight endoscope. Twenty CT angiograms were examined to measure the depth of the pineal gland, slope of the tentorial surface of the cerebellum, and angle of approach to the pineal gland in each approach. RESULTS The midline supracerebellar route is the shortest and provides direct exposure of the pineal gland, although the culmen and inferior and superior vermian tributaries of the vein of Galen frequently block this exposure. The off-midline routes provide a surgical exposure that, although slightly deeper, may reduce the need for venous sacrifice at both the level of the veins from the superior cerebellar surface entering the tentorial sinuses and at the level of the tributaries of the vein of Galen in the quadrigeminal cistern, and require less cerebellar retraction. Shifting from midline to off-midline exposure also provides a better view of the cerebellomesencephalic fissure, collicular plate, and trochlear nerve than the midline approaches. Endoscopic assistance may aid exposure of the pineal gland while preserving the bridging veins. CONCLUSIONS Understanding the characteristics of different infratentorial routes to the pineal gland will aid in gaining a better view of the pineal gland and cerebellomesencephalic fissure and may reduce the need for venous sacrifice at the level of the tentorial sinuses draining the upper cerebellar surface and the tributaries of the vein of Galen. PMID- 27715437 TI - Aggressive resection at the infiltrative margins of glioblastoma facilitated by intraoperative fluorescein guidance. AB - OBJECTIVE Extent of resection is an important prognostic factor in patients undergoing surgery for glioblastoma (GBM). Recent evidence suggests that intravenously administered fluorescein sodium associates with tumor tissue, facilitating safe maximal resection of GBM. In this study, the authors evaluate the safety and utility of intraoperative fluorescein guidance for the prediction of histopathological alteration both in the contrast-enhancing (CE) regions, where this relationship has been established, and into the non-CE (NCE), diffusely infiltrated margins. METHODS Thirty-two patients received fluorescein sodium (3 mg/kg) intravenously prior to resection. Fluorescence was intraoperatively visualized using a Zeiss Pentero surgical microscope equipped with a YELLOW 560 filter. Stereotactically localized biopsy specimens were acquired from CE and NCE regions based on preoperative MRI in conjunction with neuronavigation. The fluorescence intensity of these specimens was subjectively classified in real time with subsequent quantitative image analysis, histopathological evaluation of localized biopsy specimens, and radiological volumetric assessment of the extent of resection. RESULTS Bright fluorescence was observed in all GBMs and localized to the CE regions and portions of the NCE margins of the tumors, thus serving as a visual guide during resection. Gross total resection (GTR) was achieved in 84% of the patients with an average resected volume of 95%, and this rate was higher among patients for whom GTR was the surgical goal (GTR achieved in 93.1% of patients, average resected volume of 99.7%). Intraoperative fluorescein staining correlated with histopathological alteration in both CE and NCE regions, with positive predictive values by subjective fluorescence evaluation greater than 96% in NCE regions. CONCLUSIONS Intraoperative administration of fluorescein provides an easily visualized marker for glioma pathology in both CE and NCE regions of GBM. These findings support the use of fluorescein as a microsurgical adjunct for guiding GBM resection to facilitate safe maximal removal. PMID- 27715438 TI - Prediction and detection of seizures from simultaneous thalamic and scalp electroencephalography recordings. AB - OBJECTIVE The authors explored the feasibility of seizure detection and prediction using signals recorded from the anterior thalamic nucleus, a major target for deep brain stimulation (DBS) in the treatment of epilepsy. METHODS Using data from 5 patients (13 seizures in total), the authors performed a feasibility study and analyzed the performance of a seizure prediction and detection algorithm applied to simultaneously acquired scalp and thalamic electroencephalography (EEG). The thalamic signal was obtained from DBS electrodes. The applied algorithm used the similarity index as a nonlinear measure for seizure identification, with patient-specific channel and threshold selection. Receiver operating characteristic (ROC) curves were calculated using data from all patients and channels to compare the performance between DBS and EEG recordings. RESULTS Thalamic DBS recordings were associated with a mean prediction rate of 84%, detection rate of 97%, and false-alarm rate of 0.79/hr. In comparison, scalp EEG recordings were associated with a mean prediction rate of 71%, detection rate of 100%, and false-alarm rate of 1.01/hr. From the ROC curves, when considering all channels, DBS outperformed EEG for both detection and prediction of seizures. CONCLUSIONS This is the first study to compare automated seizure detection and prediction from simultaneous thalamic and scalp EEG recordings. The authors have demonstrated that signals recorded from DBS leads are more robust than EEG recordings and can be used to predict and detect seizures. These results indicate feasibility for future designs of closed-loop anterior nucleus DBS systems for the treatment of epilepsy. PMID- 27715439 TI - Effect of statin treatment on vasospasm-related morbidity and functional outcome in patients with aneurysmal subarachnoid hemorrhage: a systematic review and meta analysis. AB - OBJECTIVE The efficacy of statin therapy in treating aneurysmal subarachnoid hemorrhage (SAH) remains controversial. In this meta-analysis, the authors investigated whether statin treatment significantly reduced the incidence of cerebral vasospasm and delayed neurological deficits, promoting a better outcome after aneurysmal SAH. METHODS A literature search of the PubMed, Ovid, and Cochrane Library databases was performed for randomized controlled trials (RCTs) and prospective cohort studies investigating the effect of statin treatment. The end points of cerebral vasospasm, delayed ischemic neurological deficit (DIND), delayed cerebral infarction, mortality, and favorable outcome were statistically analyzed. RESULTS Six RCTs and 2 prospective cohort studies met the eligibility criteria, and a total of 1461 patients were included. The meta-analysis demonstrated a significant decrease in the incidence of cerebral vasospasm (relative risk [RR] 0.76, 95% confidence interval [CI] 0.61-0.96) in patients treated with statins after aneurysmal SAH. However, no significant benefit was observed for DIND (RR 0.88, 95% CI 0.70-1.12), delayed cerebral infarction (RR 0.66, 95% CI 0.33-1.31), mortality (RR 0.69, 95% CI 0.39-1.24) or favorable outcome, according to assessment by the modified Rankin Scale or Glasgow Outcome Scale (RR 0.99, 95% CI 0.92-1.17). CONCLUSIONS Treatment with statins significantly decreased the occurrence of vasospasm after aneurysmal SAH. The incidence of DIND, delayed cerebral infarction, and mortality were not affected by statin treatment. Future research should focus on DIND and how statins influence DIND. PMID- 27715440 TI - The impact of several craniotomies on transcranial motor evoked potential monitoring during neurosurgery. AB - OBJECTIVE Transcranial motor evoked potential (tMEP) monitoring is popular in neurosurgery; however, the accuracy of tMEP can be impaired by craniotomy. Each craniotomy procedure and changes in the CSF levels affects the current spread. The aim of this study was to investigate the influence of several craniotomies on tMEP monitoring by using C3-4 transcranial electrical stimulation (TES). METHODS The authors used the finite element method to visualize the electric field in the brain, which was generated by TES, using realistic 3D head models developed from T1-weighted MR images. Surfaces of 5 layers of the head (brain, CSF, skull, subcutaneous fat, and skin layer) were separated as accurately as possible. The authors created 5 models of the head, as follows: normal head; frontotemporal craniotomy; parietal craniotomy; temporal craniotomy; and occipital craniotomy. The computer simulation was investigated by finite element methods, and clinical recordings of the stimulation threshold level of upper-extremity tMEP (UE-tMEP) during neurosurgery were also studied in 30 patients to validate the simulation study. RESULTS Bone removal during the craniotomy positively affected the generation of the electric field in the motor cortex if the motor cortex was just under the bone at the margin of the craniotomy window. This finding from the authors' simulation study was consistent with clinical reports of frontotemporal craniotomy cases. A major decrease in CSF levels during an operation had a significantly negative impact on the electric field when the motor cortex was exposed to air. The CSF surface level during neurosurgery depends on the body position and location of the craniotomy. The parietal craniotomy and temporal craniotomy were susceptible to the effect of the changing CSF level, based on the simulation study. A marked increase in the threshold following a decrease in CSF was actually recorded in clinical reports of the UE-tMEP threshold from a temporal craniotomy. However, most frontotemporal craniotomy cases were minimally affected by a small decrease in CSF. CONCLUSIONS Bone removal during a craniotomy positively affects the generation of the electric field in the motor cortex if the motor cortex is just under the bone at the margin of the craniotomy window. The CSF decrease and the shifting brain can negatively affect tMEP ignition. These changes should be minimized to maintain the original conductivity between the motor cortex and the skull, and the operation team must remember the fluctuation of the tMEP threshold.

While secretion has been implicated in the transfer of many proteins, including prions and alpha synuclein, tunneling nanotubes (TNTs) have also been demonstrated for prions and mutant Huntingtin. Here, we provide further evidence that Tau aggregates, which have been demonstrated to predominantly be transferred via secretion, can also be found in TNTs. Additionally, cells that have taken up Tau have increased TNT formation. Coupled with previous evidence that other amyloidogenic aggregates also induce TNT formation we propose that misfolded protein aggregates can, through a common mechanism, promote the formation of TNTs and thereby their own intercellular transfer, contributing to the propagation of pathology. PMID- 27715441 TI - Specific genomic cues regulate Cajal body assembly. AB - The assembly of specialized sub-nuclear microenvironments known as nuclear bodies (NBs) is important for promoting efficient nuclear function. In particular, the Cajal body (CB), a prominent NB that facilitates spliceosomal snRNP biogenesis, assembles in response to genomic cues. Here, we detail the factors that regulate CB assembly and structural maintenance. These include the importance of transcription at nucleating gene loci, the grouping of these genes on human chromosomes 1, 6 and 17, as well as cell cycle and biochemical regulation of CB protein function. We also speculate on the correlation between CB formation and RNA splicing levels in neurons and cancer. The timing and location of these specific molecular events is critical to CB assembly and its contribution to genome function. However, further work is required to explore the emerging biophysical characteristics of CB assembly and the impact upon subsequent genome reorganization. PMID- 27715447 TI - Recombinant fungal entomopathogen RNAi target insect gene. AB - RNA interference (RNAi) technology is considered as an alternative for control of pests. However, RNAi has not been used in field conditions yet, since delivering exogenous ds/siRNA to target pests is very difficult. The laboratory methods of introducing the ds/siRNA into insects through feeding, micro feeding / dripping and injecting cannot be used in fields. Transgenic crop is perhaps the most effective application of RNAi for pest control, but it needs long-time basic researches in order to reduce the cost and evaluate the safety. Therefore, transgenic microbe is maybe a better choice. Entomopathogenic fungi generally invade the host insects through cuticle like chemical insecticides contact insect to control sucking sap pests. Isaria fumosorosea is a common fungal entomopathogen in whitefly, Bemisia tabaci. We constructed a recombinant strain of I. fumosorosea expressing specific dsRNA of whitefly's TLR7 gene. It could silence the TLR7 gene and improve the virulence against whitefly. Transgenic fungal entomopathogen has shown great potential to attain the application of RNAi technology for pests control in fields. In the future, the research interests should be focused on the selection of susceptible target pests and their vital genes, and optimizing the methods for screening genes and recombinants as well. PMID- 27715446 TI - Chemotactic G protein-coupled receptors control cell migration by repressing autophagosome biogenesis. AB - Chemotactic migration is a fundamental behavior of cells and its regulation is particularly relevant in physiological processes such as organogenesis and angiogenesis, as well as in pathological processes such as tumor metastasis. The majority of chemotactic stimuli activate cell surface receptors that belong to the G protein-coupled receptor (GPCR) superfamily. Although the autophagy machinery has been shown to play a role in cell migration, its mode of regulation by chemotactic GPCRs remains largely unexplored. We found that ligand-induced activation of 2 chemotactic GPCRs, the chemokine receptor CXCR4 and the urotensin 2 receptor UTS2R, triggers a marked reduction in the biogenesis of autophagosomes, in both HEK-293 and U87 glioblastoma cells. Chemotactic GPCRs exert their anti-autophagic effects through the activation of CAPNs, which prevent the formation of pre-autophagosomal vesicles from the plasma membrane. We further demonstrated that CXCR4- or UTS2R-induced inhibition of autophagy favors the formation of adhesion complexes to the extracellular matrix and is required for chemotactic migration. Altogether, our data reveal a new link between GPCR signaling and the autophagy machinery, and may help to envisage therapeutic strategies in pathological processes such as cancer cell invasion. PMID- 27715443 TI - Emerging connections between RNA and autophagy. AB - Macroautophagy/autophagy is a key catabolic process, essential for maintaining cellular homeostasis and survival through the removal and recycling of unwanted cellular material. Emerging evidence has revealed intricate connections between the RNA and autophagy research fields. While a majority of studies have focused on protein, lipid and carbohydrate catabolism via autophagy, accumulating data supports the view that several types of RNA and associated ribonucleoprotein complexes are specifically recruited to phagophores (precursors to autophagosomes) and subsequently degraded in the lysosome/vacuole. Moreover, recent studies have revealed a substantial number of novel autophagy regulators with RNA-related functions, indicating roles for RNA and associated proteins not only as cargo, but also as regulators of this process. In this review, we discuss widespread evidence of RNA catabolism via autophagy in yeast, plants and animals, reviewing the molecular mechanisms and biological importance in normal physiology, stress and disease. In addition, we explore emerging evidence of core autophagy regulation mediated by RNA-binding proteins and noncoding RNAs, and point to gaps in our current knowledge of the connection between RNA and autophagy. Finally, we discuss the pathological implications of RNA-protein aggregation, primarily in the context of neurodegenerative disease. PMID- 27715450 TI - More wrinkles to Bt susceptibility. PMID- 27715448 TI - Membrane orientation dynamics of lipid-modified small GTPases. AB - Lipid-modified GTPases in the Ras superfamily that mediate a variety of cell signaling processes were thought to be passively anchored to membranes. However, an increasing number of recent studies are finding that membrane binding of these proteins is hardly a passive process, and it involves the soluble catalytic domain as well as the lipid anchor. The catalytic domain adopts multiple orientations on the membrane surface due to internal fluctuations that are modulated by activation status and mutations. Distinct orientation preferences among small GTPases likely lead to differential signaling outcomes, as downstream effectors can sense different orientations. We review recent studies behind this important conclusion. PMID- 27715449 TI - Cdc42 in actin dynamics: An ordered pathway governed by complex equilibria and directional effector handover. AB - The small GTPase, Cdc42, is a key regulator of actin dynamics, functioning to connect multiple signals to actin polymerization through effector proteins of the Wiskott-Aldrich syndrome protein (WASP) and Transducer of Cdc42-dependent actin assembly (TOCA) families. WASP family members serve to couple Cdc42 with the actin nucleator, the Arp2/3 complex, via direct interactions. The regulation of these proteins in the context of actin dynamics has been extensively studied. Studies on the TOCA family, however, are more limited and relatively little is known about their roles and regulation. In this commentary we highlight new structural and biophysical insight into the involvement of TOCA proteins in the pathway of Cdc42-dependent actin dynamics. We discuss the biological implications of the low affinity interactions between the TOCA family and Cdc42, as well as probing the sequential binding of TOCA1 and the WASP homolog, N-WASP, to Cdc42. We place our current research in the context of the wealth of biophysical, structural and functional data from earlier studies pertaining to the Cdc42/N WASP/Arp2/3 pathway of actin polymerization. Finally, we describe the molecular basis for a sequential G protein-effector handover from TOCA1 to N-WASP. PMID- 27715452 TI - Cabozantinib inhibits tumor growth and metastasis of a patient-derived xenograft model of papillary renal cell carcinoma with MET mutation. AB - MET plays an important role in the development and progression of papillary renal cell carcinoma (pRCC). Evaluation of efficacy of MET inhibitors against pRCC has been hampered by limited preclinical models depicting MET abnormalities. We established a new patient-derived xenograft (PDX) model of pRCC carrying an activating mutation of MET and tested the ability of cabozantinib, an inhibitor of receptor tyrosine kinases including MET, to inhibit tumor growth and metastasis. Precision-cut, thin tissue slices from a pRCC specimen obtained by nephrectomy were implanted under the renal capsule of RAG2-/-gammaC-/- mice to establish first generation TSG-RCC-030. Histologic and genetic fidelity and metastatic potential of this model were characterized by immunohistochemistry, direct DNA sequencing and quantitative polymerase chain reaction (qPCR). The effect of cabozantinib on tumor growth and metastasis was evaluated. Whether measurements of circulating tumor DNA (ctDNA) by allele-specific qPCR could be used as a biomarker of tumor growth and response to therapy was determined. Subrenal and subcutaneous tumor grafts showed high take rates and metastasized to the lung. Both primary tumors and metastases expressed typical markers of pRCC and carried the same activating MET mutation as the parental tumor. Cabozantinib treatment caused striking tumor regression and inhibited lung metastasis in TSG RCC-030. Plasma ctDNA levels correlated with tumor volume in control mice and changed in response to cabozantinib treatment. TSG-RCC-030 provides a realistic preclinical model to better understand the development and progression of pRCC with MET mutation and accelerate the development of new therapies for pRCC.

AB - The present study investigates the role of quorum sensing (QS) molecules expressed by C. sakazakii in biofilm formation and extracellular polysaccharide expression. The QS signaling was detected using Chromobacterium violaceum 026 and Agrobacterium tumefaciens NTL4(pZLR4) based bioassay. Long chain N-acyl homoserine lactones (AHLs) with C6- C18 chain length were identified using High Performance Liquid Chromatography and Liquid Chromatography-High Resolution Mass Spectrometry. A higher Specific Biofilm Formation (SBF) index (p < 0.05) with the presence of genes associated with cellulose biosynthesis (bcsA, bcsC and bcsG) was observed in the strains. AHLs and their mechanisms can serve as novel targets for developing technologies to eradicate and prevent biofilm formation by C. sakazakii. PMID- 27715451 TI - Assembly and trafficking of box C/D and H/ACA snoRNPs. AB - Box C/D and box H/ACA snoRNAs are abundant non-coding RNAs that localize in the nucleolus and mostly function as guides for nucleotide modifications. While a large pool of snoRNAs modifies rRNAs, an increasing number of snoRNAs could also potentially target mRNAs. ScaRNAs belong to a family of specific RNAs that localize in Cajal bodies and that are structurally similar to snoRNAs. Most scaRNAs are involved in snRNA modification, while telomerase RNA, which contains H/ACA motifs, functions in telomeric DNA synthesis. In this review, we describe how box C/D and H/ACA snoRNAs are processed and assembled with core proteins to form functional RNP particles. Their biogenesis involve several transport factors that first direct pre-snoRNPs to Cajal bodies, where some processing steps are believed to take place, and then to nucleoli. Assembly of core proteins involves the HSP90/R2TP chaperone-cochaperone system for both box C/D and H/ACA RNAs, but also several factors specific for each family. These assembly factors chaperone unassembled core proteins, regulate the formation and disassembly of pre-snoRNP intermediates, and control the activity of immature particles. The AAA+ ATPase RUVBL1 and RUVBL2 belong to the R2TP co-chaperones and play essential roles in snoRNP biogenesis, as well as in the formation of other macro-molecular complexes. Despite intensive research, their mechanisms of action are still incompletely understood. PMID- 27715453 TI - Leukocyte transendothelial migration: A local affair. AB - Inflammation is part of the complex biological response of body tissues to harmful stimuli, such as pathogens. It serves as a protective response that involves leukocytes, blood vessels and molecular mediators with the purpose to eliminate the initial cause of cell injury and to initiate tissue repair. Inflammation is tightly regulated by the body and is associated with transient crossing of leukocytes through the blood vessel wall, a process called transendothelial migration (TEM) or diapedesis. TEM is a close collaboration between leukocytes on one hand and the endothelium on the other. Limiting vascular leakage during TEM but also when the leukocyte has crossed the endothelium is essential for maintaining vascular homeostasis. Although many details have been uncovered during the recent years, the molecular mechanisms from the vascular part that drive TEM still shows significant gaps in our understanding. This review will focus on the local signals that are induced in the endothelium that regulate leukocyte TEM and simultaneous preservation of endothelial barrier function. PMID- 27715455 TI - Assessment of geriatric syndromes and physical function in people living with HIV. AB - As the number of older adults living with HIV continues to increase, understanding how to incorporate geriatric assessments within HIV care will be critical. Assessment of geriatric syndromes and physical function can be useful tools for HIV clinicians and researchers to help identify the most vulnerable older adults and to better understand the aging process in people living with HIV (PLWH). This review focuses on the assessment of falls, frailty, and physical function, first in the general population of older adults, and includes a specific focus on use of these assessments in older adults living with HIV. PMID- 27715456 TI - Sequence Based Structural Characterization and Genetic Diversity Analysis of Full Length TLR4 CDS in Crossbred and Indigenous Cattle. AB - The exploration of candidate genes for immune response in cattle may be vital for improving our understanding regarding the species specific response to pathogens. Toll-like receptor 4 (TLR4) is mostly involved in protection against the deleterious effects of Gram negative pathogens. Approximately 2.6 kb long cDNA sequence of TLR4 gene covering the entire coding region was characterized in two Indian milk cattle (Vrindavani and Tharparkar). The phylogenetic analysis confirmed that the bovine TLR4 was apparently evolved from an ancestral form that predated the appearance of vertebrates, and it is grouped with buffalo, yak, and mithun TLR4s. Sequence analysis revealed a 2526-nucleotide long open reading frame (ORF) encoding 841 amino acids, similar to other cattle breeds. The calculated molecular weight of the translated ORF was 96144 and 96040.9 Da; the isoelectric point was 6.35 and 6.42 in Vrindavani and Tharparkar cattle, respectively. The Simple Modular Architecture Research Tool (SMART) analysis identified 14 leucine rich repeats (LRR) motifs in bovine TLR4 protein. The deduced TLR4 amino acid sequence of Tharparkar had 4 different substitutions as compared to Bos taurus, Sahiwal, and Vrindavani. The signal peptide cleavage site predicted to lie between 16th and 17th amino acid of mature peptide. The transmebrane helix was identified between 635-657 amino acids in the mature peptide. PMID- 27715457 TI - Archaeal RNA ligase from thermoccocus kodakarensis for template dependent ligation. AB - Nicking-sealing RNA ligases play a significant biological role in host defense and cellular repair, and have become an important molecular tool in biomedical engineering. Due to the propensity for RNA to form secondary structures, RNA modifying enzymes with elevated optimum temperatures are highly desired. Current characterized double stranded RNA ligases, such as the bacteriophage T4 RNA ligase 2, while possessing good template dependency, are not active at elevated temperatures. The few characterized RNA ligases from thermophiles exhibit high template independency. We synthesize and characterize here, KOD RNA ligase (KOD1Rnl), a thermostable and template dependent RNA ligase from the archaeon, Thermoccocus Kodakarensis. We disclose that a 13 time reduction in template independent ligation can be achieved with the addition of a single stranded DNase, such as RecJ. We also elucidate the effects of the presence of blood proteins on the activity of KOD1Rnl. Template dependent and thermostable RNA ligases, such as KOD RNA ligase, can be utilized in RNA detection, modification and sequencing. PMID- 27715458 TI - Alternative splicing of a viral mirtron differentially affects the expression of other microRNAs from its cluster and of the host transcript. AB - Interplay between alternative splicing and the Microprocessor may have differential effects on the expression of intronic miRNAs organized into clusters. We used a viral model - the LAT long non-coding RNA (LAT lncRNA) of Marek's disease oncogenic herpesvirus (MDV-1), which has the mdv1-miR-M8-M6-M7 M10 cluster embedded in its first intron - to assess the impact of splicing modifications on the biogenesis of each of the miRNAs from the cluster. Drosha silencing and alternative splicing of an extended exon 2 of the LAT lncRNA from a newly identified 3' splice site (SS) at the end of the second miRNA of the cluster showed that mdv1-miR-M6 was a 5'-tailed mirtron. We have thus identified the first 5'-tailed mirtron within a cluster of miRNAs for which alternative splicing is directly associated with differential expression of the other miRNAs of the cluster, with an increase in intronic mdv1-miR-M8 expression and a decrease in expression of the exonic mdv1-miR-M7, and indirectly associated with regulation of the host transcript. According to the alternative 3SS used for the host intron splicing, the mdv1-miR-M6 is processed as a mirtron by the spliceosome, dispatching the other miRNAs of the cluster into intron and exon, or as a canonical miRNA by the Microprocessor complex. The viral mdv1-miR-M6 mirtron is the first mirtron described that can also follow the canonical pathway. PMID- 27715459 TI - Modelling anaerobic digestion in an industrial biogas digester: Application of lactate-including ADM1 model (Part II). AB - A modified Anaerobic Digestion Model No. 1 (ADM1xp) including lactate was applied to a full-scale biogas plant. This model considers monosaccharides to degrade through lactic acid, which further degrades majorly into acetate followed by propionate and butyrate. Experimental data were derived from the previous works in the same laboratory, and the proposed parameters were validated against batch experiments. After successful validation, the biogas plant bearing a fermenter size of 7 dam3 and operated with food waste and cattle manure was simulated. The biogas production and methane content were reliably simulated, and a good fit could be obtained against the experimental data with an average difference of less than 1%. When compared to the original ADM1 model, the performance of the lactate-incorporated model was found to be improved. Inclusion of lactate as a parameter in the ADM1xp model is recommended for an increased sensitivity and enhanced prediction principally for systems dealing with high carbohydrate and lactate loads. PMID- 27715460 TI - Bovine Sex Determining Region Y: Cloning, Optimized Expression, and Purification. AB - Sex determining region Y gene (SRY) is located on Y chromosome and encodes a protein with 229 amino acids. In this study, ORF region of SRY with a length of 690 bp was synthesized using PCR and ligated to pET28a (+), then transformed in E.coli DH5alpha. E.coli BL21 (DE3) strain was chosen to express recombinant bovine SRY protein. A set of optimization steps was taken including different concentrations of IPTG, glucose, and temperatures at differed incubation times after the induction. Results showed that temperature points and different concentrations of IPTG and glucose had a significant effect (p < 0.01) on total protein and recombinant bovine SRY. After purification, various temperatures and concentrations of IPTG showed meaningful effects (p < 0.01) on the solubility of expressed recombinant SRY. Highest soluble rSRY protein amount was achieved where 0.5 mM IPTG and 0.5% glucose was used at 20 degrees C during induction. In the absence of glucose, the highest amount of soluble recombinant SRY levels were achieved at the concentrations of 0.8 mM of IPTG at 28 degrees C, 20 degrees C, and 1.5 mM IPTG at 37 degrees C during induction for 16, 24, and 8 hours, respectively. Regarding the results obtained in this study, it could be stated that by decreasing temperature and inducer concentration, soluble bovine SRY protein expression increases. PMID- 27715461 TI - Correlation of the A-FABP Gene Polymorphism and mRNA Expression with Intramuscular Fat Content in Three-Yellow Chicken and Hetian-Black Chicken. AB - The adipocyte-type fatty acid-binding protein (A-FABP) is considered a candidate gene for fat metabolism; thus, it affects fat deposition in chickens. The present study was designed to examine the polymorphism and mRNA abundance of the A-FABP gene with intramuscular fat (IMF) in the pectoralis muscles (PM) and leg muscles (LM) of Three-yellow Chicken (TYC) and Hetian-black Chicken (HTBC). In total, 60 TYCs and 60 HTBCs were sacrificed using exsanguination at market age. The IMF contents of the PM and LM in the HTBC were significantly higher than those in the TYC. Three genotypes of the A-FABP gene first exon, AA, AB, and BB, were examined by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP), and a C51 T mutational site, which is a silent substitution mutation, was revealed. The IMF contents of the AA genotype in the PM of the HTBC were significantly higher than those in the AB genotype; thus, the C51 T mutable site is a gene marker for selecting a higher IMF content in the PM of the HTBC. The relative expression of the A-FABP mRNA in the LM of the HTBC, which was measured by quantitative real-time PCR, was significantly higher than in the TYC. A significantly positive association was detected between A-FABP expression with the IMF contents of the PM and LM of both the TYC and the HTBC. These results provide basic data that might be helpful to further research the role of the A FABP gene in fat deposition and fatty acid metabolism in chickens. PMID- 27715463 TI - Groundwater quality in alluvial and prolluvial areas under the influence of irrigated agriculture activities. AB - The aim of this study was to investigate the groundwater pollution from alluvial aquifers lying under surface agriculture activities in two geologically different areas: alluvial and prolluvial. The groundwater in investigated areas is neutral to alkaline (pH 7.05-8.45), and the major dissolved ions are bicarbonate and calcium. Groundwater samples from the alluvial area are characterized by nitrate concentration above the national maximum concentration limit (MCL) at 20.5% of samples [mean value (Me) 6.31 mg/L], arsenic concentrations greater than national MCL at 35.6% of investigated samples (Me 12.12 ug/L) and elevated concentrations of iron (Me 202.37 ug/L) and manganese (Me 355.22 ug/L) at 22.7% and 81% of investigated samples, respectively. Groundwater samples from the prolluvial area did not show significantly elevated concentrations of heavy metals, but the concentration of nitrate was considerably higher (Me 65.06 mg/L). Factor analysis positively correlates As with Mn and Fe, suggesting its natural origin. Nitrate was found in positive correlation with SO42- and Ni but in negative with NH4+, suggesting its anthropogenic origin and the relationship of these ions in the process of denitrification. The t-test analysis showed a significant difference between nitrate pollution of groundwater from alluvial and prolluvial areas. According to the chemical composition of groundwater, the process of denitrification is considered to be the main reason for the reduced presence of nitrate in the groundwater lying under alluvial deposits represented by chalk and sandstones. Denitrification in groundwater lying under prolluvial deposits represented by magmatic and metamorphic rock formations was not observed. PMID- 27715462 TI - Capsaicin reactivates hMOF in gastric cancer cells and induces cell growth inhibition. AB - Capsaicin (CAP) is the major pungent component of chili pepper and is being evaluated for use against numerous types of tumors. Although CAP is indicated to target multiple signaling pathways, exact mechanisms of how it disturb cancer cell metablism remain obscure. Recent studies revealed Sirtuin 1 (SIRT1) serves as a potential target of CAP in cancer cells, indicating a direct regulation of cancer cell histone acetylation by capsaicin. The present study evaluated the effect of CAP on gastric cancer (GC) cell lines to understand the mechanism of cell growth inhibition. The results showed that CAP could significantly suppress cell growth, while altering histone acetylation in GC cell lines. Further studies found that hMOF, a major histone acetyltranferase for H4K16, is central to CAP induced epigenetic changes. Reduced hMOF activity was detected in GC tissues, which could be restored by CAP both in vivo and in vitro. These findings revealed an important role of hMOF-mediated histone acetylation in CAP-directed anti cancer processes, and suggested CAP as a potential drug for use in gastric cancer prevention and therapy. PMID- 27715464 TI - Cell-cycle-dependent drug-resistant quiescent cancer cells induce tumor angiogenesis after chemotherapy as visualized by real-time FUCCI imaging. AB - We previously demonstrated that quiescent cancer cells in a tumor are resistant to conventional chemotherapy as visualized with a fluorescence ubiquitination cell cycle indicator (FUCCI). We also showed that proliferating cancer cells exist in a tumor only near nascent vessels or on the tumor surface as visualized with FUCCI and green fluorescent protein (GFP)-expressing tumor vessels. In the present study, we show the relationship between cell-cycle phase and chemotherapy induced tumor angiogenesis using in vivo FUCCI real-time imaging of the cell cycle and nestin-driven GFP to detect nascent blood vessels. We observed that chemotherapy-treated tumors, consisting of mostly of quiescent cancer cells after treatment, had much more and deeper tumor vessels than untreated tumors. These newly-vascularized cancer cells regrew rapidly after chemotherapy. In contrast, formerly quiescent cancer cells decoyed to S/G2 phase by a telomerase-dependent adenovirus did not induce tumor angiogenesis. The present results further demonstrate the importance of the cancer-cell position in the cell cycle in order that chemotherapy be effective and not have the opposite effect of stimulating tumor angiogenesis and progression. PMID- 27715465 TI - Comparison of Cryopreservation Protocols (Single and Two-steps) and Thawing (Fast and Slow) for Canine Sperm. AB - In addition to the existence of several cryopreservation protocols, no systematic research has been carried out in order to confirm the suitable protocol for canine sperm. This study aims to assess the effect of adding 5% glycerol during cryopreservation at 37 degrees C (one-step) and 5 degrees C (two-steps), in addition of testing two thawing protocols (37 degrees C for 30 seconds, and 70 degrees C for 8 seconds). We used 12 sperm samples divided into four experimental groups: Single-Step - Slow Thawing Group; Two-Step - Slow Thawing Group; Single Step - Fast Thawing Group; and Two-Step - Fast Thawing Group. Frozen-thawed samples were submitted to automated analysis of sperm motility, evaluation of plasmatic membrane integrity, acrosomal integrity, mitochondrial activity, sperm morphology, sperm susceptibility to oxidative stress, and sperm binding assay to perivitellinic membrane of chicken egg yolk. Considering the comparison between freezing protocols, no statistical differences were verified for any of the response variables. When comparison between thawing protocols was performed, slow thawing protocol presented higher sperm count bound to perivitelline membrane of chicken egg yolk, compared to fast thawing protocol. Regardless of the freezing process, the slow thawing protocol can be recommended for the large scale cryopreservation of canine semen, since it shows a consistent better functional result. PMID- 27715467 TI - Molecular identification and nanoremediation of microbial contaminants in algal systems using untreated wastewater. AB - Wastewater-algal biomass is a promising option to biofuel production. However, microbial contaminants constitute a substantial barrier to algal biofuel yield. A series of algal strains, Nannochloris oculata and Chlorella vulgaris samples (n = 30), were purchased from the University of Texas, and were used for both stock flask cultures and flat-panel vertical bioreactors. A number of media were used for isolation and differentiation of potential contaminants according to laboratory standards (CLSI). Conventional PCR amplification was performed followed by 16S rDNA sequencing to identify isolates at the species level. Nanotherapeutics involving a nanomicellar combination of natural chitosan and zinc oxide (CZNPs) were tested against the microbial lytic groups through Minimum Inhibitory Concentration (MIC) tests and Transmission Electronic Microscopy (TEM). Results indicated the presence of Pseudomonas spp., Bacillus pumilus/ safensis, Cellulosimicrobium cellulans, Micrococcus luteus and Staphylococcus epidermidis strains at a substantial level in the wastewater-fed algal reactors. TEM confirmed the effectiveness of CZNPs on the lytic group while the average MICs (mg/mL) detected for the strains, Pseudomonas spp, Micrococcus luteus, and Bacillus pumilus were 0.417, 3.33, and 1.458, respectively. Conclusively, CZNP antimicrobials proved to be effective as inhibitory agents against currently identified lytic microbial group, did not impact algae cells, and shows promise for in situ interventions. PMID- 27715469 TI - SOTIO. PMID- 27715466 TI - Monoclonal antibodies protect from Staphylococcal Enterotoxin K (SEK) induced toxic shock and sepsis by USA300 Staphylococcus aureus. AB - Staphylococcus aureus is a leading infectious cause of life-threatening disease in humans, yet there is currently no vaccine to combat this bacterium. The pathogenesis of S. aureus is mediated by a diverse array of protein toxins including a large family of secreted pyrogenic superantigens. Neutralization of superantigens, including SEB and TSST-1, has proven to be protective in several animal models of toxic shock and sepsis. We demonstrate, for the first time, that a far more prevalent staphylococcal superantigen, SEK, can also induce lethal shock in mice. Additionally, we describe monoclonal antibodies (mAbs) that inhibit SEK-induced mitogenicity as well as protect against SEK-induced lethality, and enhance survival from S. aureus septicemia in murine models. MAb 4G3 (IgG2b), mAb-5G2 (IgG1), and mAb-9H2 (IgG1), all inhibit SEK-induced proliferation and cytokine production of human immune cells. We then demonstrate that passive immunization with a combination of mAb-4G3 and mAb-5G4, 2 mAbs that do not compete for epitope(s) on SEK, significantly enhance survival in a murine model of SEK-induced toxic shock (p = 0.006). In the setting of sepsis, passive immunization with this combination of mAbs also significantly enhances survival in mice after challenge with CA-MRSA strain USA300 (p = 0.03). Furthermore, septic mice that received mAb treatment in conjunction with vancomycin exhibit less morbidity than mice treated with vancomycin alone. Taken together, these findings suggest that the contribution of SEK to S. aureus pathogenesis may be greater than previously appreciated, and that adjunctive therapy with passive immunotherapy against SEs may be beneficial. PMID- 27715470 TI - Improvement of lincomycin production by mutant selection and metabolic regulation. AB - Lincomycin is a lincosamide antibiotic produced by Streptomyces lincolnensis. Through mutagenesis by ethylmethansulfonate (EMS) and ultraviolet (UV) irradiation repeatedly, M2 was picked out in plate with glutamine and propylproline orderly. In 50-L stirred bioreactor, the production of lincomycin, fermented by M2, was increased to 8136 u/ml under the optimal condition as compared to original strain S. lincolnensis 07-5 (6634 u/ml). Two-dimensional gel electrophoresis (2-D GE) and mass spectrometry (MS)-shown LmbG, LmbI, and acetohydroxy acid isomeroreductase were remarkably synthesized in M2. The gene lmbG and lmbI are responsible for methylation in the lincomycin biosynthetic cluster, while acetohydroxy acid isomeroreductase contributes to stronger metabolic capability. Finally, we obtained a better strain for industrial production. PMID- 27715471 TI - The contribution of capsule polysaccharide genes to virulence of Klebsiella pneumoniae. PMID- 27715472 TI - A novel process for the production of high-purity galactooligosaccharides (GOS) using consortium of microbes. AB - Galactooligosaccharides (GOS) are nondigestible dietary fibers which have a beneficial effect on human health by promoting the growth of probiotic bacteria in the gut. In addition, other health benefits have been reported from oligosaccharides consumption such as stimulation of intestinal mobility, colon cancer prevention, mineral absorption as well as protection against certain pathogenic bacterial infections. The goal of this research was to develop an efficient biotransformation system using a consortium of microbes for the production of >=85% pure GOS and reusing the cell biomass in repeated cycles of biotransformation. Production of GOS by lactose transgalactosylation using whole cells of Sporobolomyces singularis MTCC 5491 as a source of beta-galactosidase and monosaccharides utilization by yeast isolate (NUTIDY007) were studied. For increasing the purity of GOS, growth and bioconversion parameters on the transgalactosylation by the whole cells were investigated. Further, continuous production of GOS was studied in a reactor with microfiltration membrane system. A maximum GOS purity of 42% was achieved using single culture of S. singularis. Under optimized conditions, single culture of S. singularis produced a maximum of 56% pure GOS. Addition of second culture to the reaction mixture for utilization of glucose significantly increased the GOS purity from 56% to >=85%. The product consisted of tri- to penta-galactooligosaccharides. Trisaccharides were the main component of the reaction mixture. A maximum productivity of 10.9 g/L/hr was obtained under the optimum conditions.

AB - : Assessments of past environmental policies-termed accountability studies contribute important information to the decision-making process used to review the efficacy of past policies, and subsequently aid in the development of effective new policies. These studies have used a variety of methods that have achieved varying levels of success at linking improvements in air quality and/or health to regulations. The Health Effects Institute defines the air pollution accountability framework as a chain of events that includes the regulation of interest, air quality, exposure/dose, and health outcomes, and suggests that accountability research should address impacts for each of these linkages. Early accountability studies investigated short-term, local regulatory actions (for example, coal use banned city-wide on a specific date or traffic pattern changes made for Olympic Games). Recent studies assessed regulations implemented over longer time and larger spatial scales. Studies on broader scales require accountability research methods that account for effects of confounding factors that increase over time and space. Improved estimates of appropriate baseline levels (sometimes termed "counterfactual"-the expected state in a scenario without an intervention) that account for confounders and uncertainties at each link in the accountability chain will help estimate causality with greater certainty. In the direct accountability framework, researchers link outcomes with regulations using statistical methods that bypass the link-by-link approach of classical accountability. Direct accountability results and methods complement the classical approach. New studies should take advantage of advanced planning for accountability studies, new data sources (such as satellite measurements), and new statistical methods. Evaluation of new methods and data sources is necessary to improve investigations of long-term regulations, and associated uncertainty should be accounted for at each link to provide a confidence estimate of air quality regulation effectiveness. The final step in any accountability is the comparison of results with the proposed benefits of an air quality policy. IMPLICATIONS: The field of air pollution accountability continues to grow in importance to a number of stakeholders. Two frameworks, the classical accountability chain and direct accountability, have been used to estimate impacts of regulatory actions, and both require careful attention to confounders and uncertainties. Researchers should continue to develop and evaluate both methods as they investigate current and future air pollution regulations.

AB - The present study used an open-ended survey to collect information about current eating practices and coping strategies among 218 retired female athletes. An inductive and deductive thematic analysis revealed three themes relevant to the intuitive eating framework-permission to eat; recognizing internal hunger and satiety cues; and eating to meet physical and nutritional needs. Athletes described feeling liberated with regards to their eating following retirement from sport, and for some this included an alleviation of disordered eating practices. These changes, however, required an effortful process of recalibration, during which athletes had to relearn and reinterpret their body's physiological signals of hunger and satiety. Additional research is needed to understand just how this process unfolds and how retired athletes can be supported in developing a healthier and more adaptive approach to eating. PMID- 27715476 TI - Individualized Laparoscopic Therapy for Portal Hypertension: A Preliminary Single Center Experience. AB - BACKGROUND: To investigate the effects and technical points of several individualized laparoscopic therapies for patients suffering from cirrhotic portal hypertension. METHODS: In total, 385 cirrhotic patients who underwent the treatment of individualized laparoscopic therapy from February 2012 to December 2015 at the Clinical Medical College of Yangzhou University were enrolled in this study. We retrospectively analyzed the clinical data and the key technical points. RESULTS: Individualized laparoscopic therapies were successfully performed on 379 of 385 cases. Six cases were converted to a laparotomy (the rate of conversion to laparotomy was 1.6%). Modified laparoscopic splenectomy (MLS) for cirrhotic patients with hypersplenism was successfully performed on 103 of 105 cases. Laparoscopic azygoportal disconnection for cirrhotic patients with esophagogastric variceal bleeding (EGVB) or F3 varices was successfully performed on 61 of 62 cases, and modified laparoscopic splenectomy and azygoportal disconnection (MLSD) for cirrhotic patients with hypersplenism and EGVB or F3 varices was successfully performed on 196 of 201 cases. Synchronous MLS and laparoscopic partial hepatectomy (SLSH) for cirrhotic patients with hypersplenism and hepatocellular carcinoma (HCC) and synchronous MLSD and laparoscopic partial hepatectomy (SLSDH) for cirrhotic patients with hypersplenism, EGVB or F3 varices and HCC were all successfully implemented on 12 and 5 patients, respectively. From May 2013, we used the intraoperative autologous cell salvage during each individualized laparoscopic procedure. CONCLUSIONS: An individualized laparoscopic therapy was beneficial for different state of selected cirrhotic patients with portal hypertension with or without HCC.

AB - This article reports the validation of the Chinese versions of the Suicidal Ideation Attributes Scale (SIDAS), the short form of Stigma of Suicide Scale (SOSS), and the short form of Literacy of Suicide Scale (LOSS) among 57 Chinese and English bilinguals and 224 Chinese university students. All the translated scales showed high correlations with the original versions. The translated SIDAS and refined SOSS demonstrated robust factor structures, good internal consistency, and convergent validity. Chinese students with self-reported depression symptoms tended to have higher glorification of suicide and lower suicide literacy. These brief scales fill an important gap in evaluating suicide outcomes in Chinese-speaking societies. PMID- 27715479 TI - Effects of Visual Error Timing on Smooth Pursuit Gain Adaptation in Humans. AB - Smooth pursuit (SP) is one of the precise oculomotor behaviors when tracking a moving object. Adaptation of SP is based on a visual-error driven motor learning process associated with predictable changes in the visual environment. Proper timing of a sensory signal is an important factor for adaptation of fine motor control. In this study, we investigated whether visual error timing affects SP gain adaptation. An adaptive change in SP gain is produced experimentally by repeated trials of a step-ramp tracking with 2 different velocities (double velocity paradigm). The authors used the double-velocity paradigm where target speed changes 400 or 800 ms after the target onset. The results show that SP gain changed in a certain time window following adaptation. The authors suggest that SP adaptation shown in this study is associated with timing control mechanisms. PMID- 27715480 TI - The Effect of External and Internal Focus of Attention on Gait Variability in Older Adults. AB - Internal focus of attention on a movement or focusing on an external target are both strategies that can affect motor performance. The authors explored whether manipulating subjects' focus of attention while walking would alter gait variability, a measure reflecting consistency of gait and associated with the risk of falling in older adults. Twenty community-living older adults participated in the study and were tested while focusing their attention on (a) gait consistency (internal focus) or (b) metronome beats (external focus). In both conditions gait variability increased (i.e., worsened p < .05) or did not change. No benefit was found in instructing subjects to focus on gait consistency or metronome beats. Such instructions may actually have distracted and interfered with the execution of gait.

AB - The objective of this study was to assess the concentration levels of trace metals (Zn, Hg, Cd, Cr, Ni, Pb and Cu) in surface water and bottom sediments of the Hungarian upper section of the Danube River and its main tributaries. A total of 935 samples (water and sediments) were collected from 10 different sampling sites in the period of 2001-2012 and analyzed for the trace metals. Moreover, the dissolved arsenic content was determined in a number of 467 water samples in the period of 2004-2012. The highest dissolved trace element concentrations were observed at the site of Kenyermezei-patak Creek located near a hazardous waste incinerator. However, the comparison of the dissolved trace metal(loid) concentrations determined with other sections of the Danube River and the European Union environmental quality standards revealed that the dissolved trace metal(loid) concentrations were relatively low in the Hungarian upper section during the 12-year study period (excluding some samples for Hg, Cd and Cr). The concentrations of trace metals in sediments were higher than those found in water samples and varied very much in all sampling sites during the study period. The sediment samples were mainly classified as low or moderate polluted for trace metals. However, some sediment samples collected especially from the Moson Danube branch indicated a considerable (for Zn, Hg, Cd, Ni and Cu) or a very high (for Zn and Hg) contamination.

AB - Nucleic acid aptamers are single-stranded DNA or RNA oligonucleotide sequences that bind to a specific target molecule with high affinity and specificity through their ability to adopt 3-dimensional structure in solution. Aptamers have huge potential as targeted therapeutics, diagnostics, delivery agents and as biosensors. However, aptamers composed of natural nucleotide monomers are quickly degraded in vivo and show poor pharmacodynamic properties. To overcome this, chemically-modified nucleic acid aptamers are developed by incorporating modified nucleotides after or during the selection process by Systematic Evolution of Ligands by EXponential enrichment (SELEX). This review will discuss the development of chemically-modified aptamers and provide the pros and cons, and new insights on in vitro aptamer selection strategies by using chemically modified nucleic acid libraries. PMID- 27715482 TI - Calcified cephalohematoma as an unusual cause of EEG anomalies: case report. AB - Cephalohematoma, one of the most common neonatal head injuries, generally undergoes spontaneous resorption. When calcified, it may cause cranial vault distortion and depression of the inner skull layer, although it remains asymptomatic. Surgery, indeed, is usually performed for cosmetic purposes. For these reasons, the long-term effects of calcified cephalohematoma (CC) are widely unknown. The authors report the case of an 11-year-old girl with a persistent calcified CC causing skull deformity and delayed electroencephalography (EEG) anomalies. These anomalies were detected during routine control EEG and were not clinically evident. The young girl underwent surgical removal of the CC for cosmetic purpose. The EEG abnormalities disappeared after surgery, thus reinforcing the hypothesis of a correlation with the brain "compression" resulting from the CC. To the best of the authors' knowledge this is the first time that CC-associated EEG anomalies have been described: even though these anomalies cannot be considered an indication for surgery, they merit late follow up in case of skull deformity.

AB - OBJECTIVE Young patients with moyamoya disease can exhibit infarction after revascularization surgery. This analysis of the characteristics of infarction after encephaloduroarteriosynangiosis (EDAS) in young patients with moyamoya disease was undertaken in an effort to elucidate the infarction mechanism. METHODS The authors retrospectively collected clinical information and reviewed pre- and postoperative MRI studies from cases involving patients younger than 18 years who underwent EDAS for the treatment of moyamoya disease between January 2012 and February 2015. Infarction patterns were categorized into watershed, territorial, or mixed pattern. The Wilcoxon rank sum test, chi-square test, and Fisher exact test were used to compare the clinical and imaging variables between patient groups. The characteristics of patients with and without postoperative infarction were compared using univariate and multivariate analysis. The cumulative proportion of patients without postoperative infarction according to operation stage was calculated using the Kaplan-Meier method and the resulting curves were compared using the log-rank test. RESULTS In 100 patients, 171 EDAS procedures had been performed. There were 38 cases of preoperative infarction in 35 patients and 20 cases of postoperative infarction in 13 patients. Territorial infarction was more frequent in the postoperative infarction group than in the preoperative infarction group (55.0% vs 37.8%, p = 0.037). Infarction was more common on the bilateral or contralateral side of the operation after first-stage EDAS (9 [75.0%] of 12 infarctions) than in the second-stage operation (2 [25.0%] of 8 infarctions), but the difference was not statistically significant (p = 0.068). The frequency of postoperative infarction was not significantly different depending on the stage of the operation (p = 0.694). CONCLUSIONS An acute infarction pattern after EDAS was more frequently territorial, suggesting an underlying occlusive mechanism. Operation stage did not affect the rate of postoperative infarction occurrence. PMID- 27715486 TI - Spin-echo Echo-planar Imaging MR Elastography versus Gradient-echo MR Elastography for Assessment of Liver Stiffness in Children and Young Adults Suspected of Having Liver Disease. AB - Purpose To compare two-dimensional (2D) gradient-recalled echo (GRE) and 2D spin echo (SE) echo-planar imaging (EPI) magnetic resonance (MR) elastography for measurement of hepatic stiffness in pediatric and young adult patients suspected of having liver disease. Materials and Methods In this institutional review board approved, HIPAA-compliant study, 58 patients underwent both 2D GRE and 2D SE-EPI MR elastography at 1.5 T during separate breath holds. Liver stiffness (mean of means; in kilopascals) was measured by five blinded reviewers. Pooled mean liver stiffness and region-of-interest (ROI) size were compared by using paired t tests. Intraclass correlation coefficients (ICCs) were used to assess agreement between techniques. Respiratory motion artifacts were compared across sequences by using the Fisher exact test. Results Mean patient age was 14.7 years +/- 5.2 (standard deviation; age range, 0.7-20.5 years), and 55.2% (32 of 58) of patients were male. Mean liver stiffness was 2.92 kPa +/- 1.29 measured at GRE MR elastography and 2.76 kPa +/- 1.39 at SE-EPI MR elastography (n = 290; P = .15). Mean ROI sizes were 8495 mm2 +/- 4482 for 2D GRE MR elastography and 15 176 mm2 +/- 7609 for 2D SE-EPI MR elastography (n = 290; P < .001). Agreement was excellent for measured stiffness between five reviewers for both 2D GRE (ICC, 0.97; 95% confidence interval: 0.95, 0.98) and 2D SE-EPI (ICC, 0.98; 95% confidence interval: 0.96, 0.99). Mean ICC (n = 5) for agreement between 2D GRE and 2D SE-EPI MR elastography was 0.93 (range, 0.91-0.95). Moderate or severe breathing artifacts were observed on 27.5% (16 of 58) of 2D GRE images versus 0% 2D SE-EPI images (P < .001). Conclusion There is excellent agreement on measured hepatic stiffness between 2D GRE and 2D SE-EPI MR elastography across multiple reviewers. SE-EPI MR elastography allowed for stiffness measurement across larger areas of the liver and can be performed in a single breath hold. (c) RSNA, 2016. PMID- 27715485 TI - Constructive edge of uridylation-induced RNA degradation. AB - RNA uridylation is a significant transcriptome-shaping factor in protists, fungi, metazoans, and plants. The 3' U-additions are catalyzed by terminal uridyltransferases (TUTases), a diverse group of enzymes that along with non canonical poly(A) polymerases form a distinct group in the superfamily of DNA polymerase beta-like nucleotidyl transferases. Within and across studied organisms and subcellular compartments, TUTases differ in nucleotide triphosphate selectivity, interacting partners, and RNA targets. A general premise linking RNA uridylation to 3'-5' degradation received support from several studies of small RNAs and mRNA turnover. However, recent work on kinetoplastid protists typified by Trypanosoma brucei provides evidence that RNA uridylation may play a more nuanced role in generating functional small RNAs. In this pathogen's mitochondrion, most mRNAs are internally edited by U-insertions and deletions, and subjected to 3' adenylation/uridylation; guide RNAs (gRNAs) required for editing are U-tailed. The prominent role of uridylation in mitochondrial RNA metabolism stimulated identification of the first TUTase, RNA editing TUTase 1 (RET1). Here we discuss functional studies of mitochondrial uridylation in trypanosomes that have revealed an unorthodox pathway of small RNA biogenesis. The current model accentuates physical coupling of RET1 and 3'-5' RNase II/RNB type exonuclease DSS1 within a stable complex termed the mitochondrial 3' processome (MPsome). In the confines of this complex, RET1 initially uridylates a long precursor to activate its 3'-5' degradation by DSS1, and then uridylates trimmed guide RNA to disengage the processing complex from the mature molecule. We also discuss a potential role of antisense transcription in the MPsome pausing at a fixed distance from gRNA's 5' end. This step likely defines the mature 3' end by enabling kinetic competition between TUTase and exonuclease activities. PMID- 27715487 TI - The eponymous legacy of Sir William Richard Gowers (1845-1915): A revealing letter. AB - The eponymous legacy of Sir William Richard Gowers (1845-1915) was the subject of a comprehensive appraisal first written for this journal late last year. Since the completion of that work, a revealing February 1903 letter has come to light recording, amongst other things, Gowers' firsthand and somewhat private opinions concerning some of his own eponymous contributions to medicine. This addendum to the primary author's original article will review and contextualize this very interesting find as it relates to Gowers' eponymous legacy. Gowers' "ataxic paraplegia" (referred to as "Gowers' disease" in the letter) and "syringal hemorrhage" are specially considered, and his broader neological contributions are also briefly addressed. For completion, a number of other previously unnoticed eponyms are added to the already impressive list of medical entities named in Gowers' honor, and a more complete collection of eponyms found in Gowers' Manual are tabulated for consideration. PMID- 27715489 TI - Problematic clinical features of children and adults with cerebral palsy who use electric powered indoor/outdoor wheelchairs: A cross-sectional study. AB - This article aims to describe the clinical features of electric powered indoor/outdoor wheelchair (EPIOC) users with cerebral palsy (CP) that are problematic to optimal prescription and to explore comorbidities, features of CP, and conditions secondary to disability impacting on equipment provision for children and adults. The method is a cross-sectional study of EPIOC users (n = 102) with a primary diagnosis of CP. This is a retrospective review of electronic and case note records of EPIOC recipients attending a specialist wheelchair service in 2007-2008. Records were reviewed by a rehabilitation consultant. Data were extracted under three themes; demographic, diagnostic/clinical and wheelchair factors. There were 48 males mean age 27.5 (range 8-70, SD 13.9) years and 54 females, mean age 29.5 (range 7-68, SD 14.6) years with CP. Sixteen comorbidities, nine features of CP, and five features of disability influenced wheelchair prescription. Sixty-four users were provided with specialized seating (SS) and 47 with tilt-in-space (TIS) seats. Complex controls were provided to 16 users, 12 tray-mounted. The majority of users had both SS and TIS. Powered wheelchair prescription has important therapeutic roles in clinical management in addition to enhancing mobility, independence and participation. Clinical features such as spasticity and problematic pain appeared less well managed in adults than in children. PMID- 27715488 TI - Changes in Multidigit Synergies and Their Feed-Forward Adjustments in Multiple Sclerosis. AB - The authors explored the changes in multidigit synergies in patients with multiple sclerosis (MS) within the framework of the uncontrolled manifold hypothesis. The specific hypotheses were that both synergy indices and anticipatory synergy adjustments prior to the initiation of a self-paced quick action would be diminished in the patients compared to age-matched controls. The MS patients and age-matched controls (n = 13 in both groups) performed one-finger and multifinger force production tasks involving both accurate steady-state force production and quick force pulses. The patients showed significantly lower maximal finger forces and a tendency toward slower force pulses. Enslaving was increased in MS, but only in the lateral fingers (index and little). Indices of multifinger synergies during steady-state force production were lower in MS, mainly due to the lower amount of intertrial variance that did not affect total force. Anticipatory synergy adjustments were significantly delayed in MS. The results show that MS leads to significant changes in multidigit synergies and feed-forward adjustments of the synergies prior to a quick action. The authors discuss possible contributions of subcortical structures to the impaired synergic control. PMID- 27715490 TI - Post-transcriptional mending of gene sequences: Looking under the hood of mitochondrial gene expression in diplonemids. AB - The instructions to make proteins and structural RNAs are laid down in gene sequences. Yet, in certain instances, these primary instructions need to be modified considerably during gene expression, most often at the transcript level. Here we review a case of massive post-transcriptional revisions via trans splicing and RNA editing, a phenomenon occurring in mitochondria of a recently recognized protist group, the diplonemids. As of now, the various post transcriptional steps have been cataloged in detail, but how these processes function is still unknown. Since genetic manipulation techniques such as gene replacement and RNA interference have not yet been established for these organisms, alternative strategies have to be deployed. Here, we discuss the experimental and bioinformatics approaches that promise to unravel the molecular machineries of trans-splicing and RNA editing in Diplonema mitochondria. PMID- 27715491 TI - Objective Evaluation of Performance Stress in Musicians With Focal Hand Dystonia: A Case Series. AB - Five musicians suffering from focal dystonia participated in a pilot study that examined the feasibility of an experimental protocol designed to assess musicians' motor performance under stress. Electrocardiography, free cortisol levels, and subjective assessments were used to monitor alterations of the hypothalamic-pituitary-adrenal axis. As measures of motor outcome, temporal variability of finger movements and muscular cocontraction of the wrist flexor and extensor were assessed. Findings suggest that the specific experimental design could be successfully applied. Several methodological issues such as carryover effects, the use of free cortisol, the inclusion of a double baseline, and the classification of dystonic patients into stress responders and nonresponders are analyzed and discussed. PMID- 27715494 TI - Spanish Validation of the Polymorphous Prejudice Scale in a Sample of University Students. AB - The shortened version of the Polymorphous Prejudice Scale (PPS) analyzes new manifestations of prejudice toward gay men and lesbian women. Specifically, this instrument consists of 16 items distributed in four subscales: values gay progress, positive beliefs about gay men, positive beliefs about lesbian women and, resistance to heteronormative expectations. The aim of the current study is to add new evidence about the reliability and validity of the scale. The scale is administrated to 348 heterosexual university students from Spain with a mean age of 22.62 years (SD = 7.63). Reliability and factorial validity estimates are presented. A four-factor structure is supported using confirmatory factor analysis (short version). Our results can be useful in planning variables for intervention programs designed to foster the tolerance and normality of sexual diversity. PMID- 27715492 TI - Connecting G protein signaling to chemoattractant-mediated cell polarity and cytoskeletal reorganization. AB - The directional movement toward extracellular chemical gradients, a process called chemotaxis, is an important property of cells. Central to eukaryotic chemotaxis is the molecular mechanism by which chemoattractant-mediated activation of G-protein coupled receptors (GPCRs) induces symmetry breaking in the activated downstream signaling pathways. Studies with mainly Dictyostelium and mammalian neutrophils as experimental systems have shown that chemotaxis is mediated by a complex network of signaling pathways. Recently, several labs have used extensive and efficient proteomic approaches to further unravel this dynamic signaling network. Together these studies showed the critical role of the interplay between heterotrimeric G-protein subunits and monomeric G proteins in regulating cytoskeletal rearrangements during chemotaxis. Here we highlight how these proteomic studies have provided greater insight into the mechanisms by which the heterotrimeric G protein cycle is regulated, how heterotrimeric G proteins-induced symmetry breaking is mediated through small G protein signaling, and how symmetry breaking in G protein signaling subsequently induces cytoskeleton rearrangements and cell migration. PMID- 27715495 TI - Motor Planning Influences the Perceived Timing of Vibrotactile Stimuli in an Amplitude-Dependent Manner. AB - The authors characterized how motor planning influences temporal order judgment (TOJ) tasks. They examined this by applying vibrotactile stimulation during the planning stages of a bimanual arm movement that would bring the arms into a crossed configuration. The authors have previously shown that planning to cross the arms induces a subjective reversal of spatially defined temporal order judgments that evolves over the course of the planning period. It was unclear, however, whether this effect is modulated by the extent to which the arms would be crossed after movement. The authors examined this issue by having participants plan to move to 4 different targets that would leave the arms in crossed configurations of varying extents. The results demonstrate that even though cutaneous stimuli were applied before the movements, if participants were planning to move into a more crossed configuration, performance on the TOJ task worsened depending on where they were in the planning process. This data suggest the brain uses planning signals to predict sensations from impending movements in a context-dependent manner. PMID- 27715493 TI - Phosphorylation of the Cajal body protein WRAP53beta by ATM promotes its involvement in the DNA damage response. AB - The cellular response to DNA double-strand breaks is orchestrated by the protein kinase ATM, which phosphorylates key actors in the DNA repair network. WRAP53beta is a multifunctional protein that controls trafficking of factors to Cajal bodies, telomeres and DNA double-strand breaks but what regulates the involvement of WRAP53beta in these separate processes remains unclear. Here, we show that in response to various types of DNA damage, including IR and UV, WRAP53beta is phosphorylated on serine residue 64 by ATM with a time-course that parallels its accumulation at DNA lesions. Interestingly, recruitment of phosphorylated WRAP53beta (pWRAP53betaS64) to sites of such DNA damage promotes its interaction with gammaH2AX at these locations. Moreover, pWRAP53betaS64 stimulates the accumulation of the repair factor 53BP1 at DNA double-strand breaks and enhances repair of this type of damage via homologous recombination and non-homologous end joining. At the same time, phosphorylation of WRAP53beta is dispensable for its localization to Cajal bodies, where it accumulates even in unstressed cells. These findings not only reveal ATM to be an upstream regulator of WRAP53beta, but also indicates that phosphorylation of WRAP53beta at serine 64 controls its involvement in the DNA damage response and may also restrict its other functions. PMID- 27715496 TI - Neural Efficiency in Expert Cognitive-Motor Performers During Affective Challenge. AB - Skilled individuals demonstrate a spatially localized or relatively lower response in brain activity characterized as neural efficiency when performing within their domain of expertise. Elite athletes are experts in their chosen sport and thus must be not only adept in the motor domain but must be resilient to performing under the stress of high-level competition. Such stability of performance suggests this population processes emotion and mental stress in an adaptive and efficient manner. This study sought to determine if athletes with a history of successful performance under circumstances of mental stress demonstrate neural efficiency during affective challenges compared to age-matched controls. Using functional magnetic resonance imaging, the blood-oxygen level dependent response was recorded during emotional challenge induced by sport specific and general unpleasant images. The athletes demonstrated neural efficiency in brain regions critical to emotion regulation (prefrontal cortex) and affect (insula) independently of their domain of expertise, suggesting adaptive processing of negative events and less emotional reactivity to unpleasant stimuli. PMID- 27715497 TI - Application of 1D and 2D MFR reactor technology for the isolation of insecticidal and anti-microbial properties from pyrolysis bio-oils. AB - Valuable chemicals can be separated from agricultural residues by chemical or thermochemical processes. The application of pyrolysis has already been demonstrated as an efficient means to produce a liquid with a high concentration of desired product. The objective of this study was to apply an insect and microorganism bioassay-guided approach to separate and isolate pesticidal compounds from bio-oil produced through biomass pyrolysis. Tobacco leaf (Nicotianata bacum), tomato plant (Solanum lycopersicum), and spent coffee (Coffea arabica) grounds were pyrolyzed at 10 degrees C/min from ambient to 565 degrees C using the mechanically fluidized reactor (MFR). With one-dimensional (1D) MFR pyrolysis, the composition of the product vapors varied as the reactor temperature was raised allowing for the selection of the temperature range that corresponds to vapors with a high concentration of pesticidal properties. Further product separation was performed in a fractional condensation train, or 2D MFR pyrolysis, thus allowing for the separation of vapor components according to their condensation temperature. The 300-400 degrees C tobacco and tomato bio-oil cuts from the 1D MFR showed the highest insecticidal and anti-microbial activity compared to the other bio-oil cuts. The 300-350 and 350-400 degrees C bio-oil cuts produced by 2D MFR had the highest insecticidal activity when the bio-oil was collected from the 210 degrees C condenser. The tobacco and tomato bio-oil had similar insecticidal activity (LC50 of 2.1 and 2.2 mg/mL) when the bio-oil was collected in the 210 degrees C condenser from the 300-350 degrees C reactor temperature gases. The 2D MFR does concentrate the pesticidal products compared to the 1D MFR and thus can reduce the need for further separation steps such as solvent extraction. PMID- 27715498 TI - Subjective Well-Being and Levels of Clinical Symptomatology in a Transwomen Sample and Men Who Have Sex with Men in Chile. AB - This paper examines the levels of subjective well-being (psychological and social well-being, subjective happiness, and satisfaction with life) and clinical symptomatology (anxiety, depression, somatization, hostility, and phobic anxiety) in a transwomen sample (n = 112). The sample was recruited through a snowball procedure in Chile (Santiago, Valparaiso, and Arica). Data obtained are compared to those from a group of Men who have Sex with Men (MSM) (n = 323). Results reveal statistically significant differences in the levels of happiness (t(157) = 2.16; p = .03; d = .25), satisfaction with life (t(154) = 3.90; p < .001; d = .47), and purpose in life (scale of psychological well-being) (t(151) = 1.99; p .04; d = .24) reported by the two groups. The transwomen group shows the lowest scores in all dimensions. However, trans women report higher levels of social coherence (t(432) = -4.96; p < .001; d = .53) on the social well-being scale, compared to the MSM group. Regarding their levels of clinical symptomatology, trans women report higher levels of anxiety (t(163) = -6.67; p < .001; d = .78), depression (t(167) = -5.61; p < .001; d = .65), somatization (t(161) = -5.10; p < .001; d = .60), hostility (t(153) = -5.38; p < .001; d = .62), and phobic anxiety (t(164) = -6.70; p < .001; d = .80). Results are discussed on the basis of the context of each group. PMID- 27715499 TI - Biodegradation of malathion, alpha- and beta-endosulfan by bacterial strains isolated from agricultural soil in Veracruz, Mexico. AB - The objective of this study was to evaluate the capacity of two bacterial strains isolated, cultivated, and purified from agricultural soils of Veracruz, Mexico, for biodegradation and mineralisation of malathion (diethyl 2 (dimethoxyphosphorothioyl) succinate) and alpha- and beta-endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6-9-methano-2,4,3 benzodioxathiepine-3-oxide). The isolated bacterial strains were identified using biochemical and morphological characterization and the analysis of their 16S rDNA gene, as Enterobacter cloacae strain PMM16 (E1) and E. amnigenus strain XGL214 (M1). The E1 strain was able to degrade endosulfan, whereas the M1 strain was capable of degrading both pesticides. The E1 strain degraded 71.32% of alpha endosulfan and 100% of beta-endosulfan within 24 days. The absence of metabolites, such as endosulfan sulfate, endosulfan lactone, or endosulfan diol, would suggest degradation of endosulfan isomers through non-oxidative pathways. Malathion was completely eliminated by the M1 strain. The major metabolite was butanedioic acid. There was a time-dependent increase in bacterial biomass, typical of bacterial growth, correlated with the decrease in pesticide concentration. The CO2 production also increased significantly with the addition of pesticides to the bacterial growth media, demonstrating that, under aerobic conditions, the bacteria utilized endosulfan and malathion as a carbon source. Here, two bacterial strains are shown to metabolize two toxic pesticides into non toxic intermediates.

AB - Although workers in meatpacking facilities in the U.S. experience high rates of occupational injury, their injury experiences have received limited research attention. Prior research indicates underreporting in injury rates in this industry as well significant variation in injury rates among facilities. To add detail to the rates and circumstances surrounding occupational injury among meatpacking workers, we conducted a cross-sectional study of workers employed at an industrial beefpacking plant in Nebraska (n = 137) and interviewed workers about recent injury experiences. We assessed frequency, cause and nature of self reported injury. We estimated annual incidence rates of self-reported injuries using the OSHA formula and compared these rates to industry-wide data. We also evaluated psychological distress in this workforce as measured by the Kessler-6 scale to assess whether distress was associated with recent occupational injury. In this study, 15.1% of workers experienced occupational injuries that required time off work, job transfer, or restriction during the past three months. The estimated annual incidence rate was 15.2 injuries per 100 full-time workers for these injuries at this plant. Rushing was identified as the cause of nearly 50% of injuries, and repetitive work as the cause of an additional 20% of injuries. Use of metal mesh sleeves (POR: 0.10 (p = 0.008)) and metal mesh gloves (POR: 0.41 (p = 0.05) were associated with reduced risk of injury. Use of a carbon steel for knife sharpening (POR: 5.2 (p = 0.02)) was associated with elevated risk of moderate and severe injury. There were no associations between self reported occupational injury and overall measures of psychological distress. Self reported incidence rate of severe injury in this plant was more than twice official industry estimates. Worker self-reports may illustrate key areas for injury prevention.

AB - Long-term settlement magnitude is influenced by changes in external and internal factors that control the microbiological activity in the landfill waste body. To improve the understanding of settlement phenomena, it is instructive to study lysimeters filled with MSW. This paper aims to understand the settlement behavior of MSW by correlating internal and external factors that influence waste biodegradation in a lysimeter. Thus, a lysimeter was built, instrumented and filled with MSW from the city of Campina Grande, the state of Paraiba, Brazil. Physicochemical analysis of the waste (from three levels of depth of the lysimeter) was carried out along with MSW settlement measurements. Statistical tools such as descriptive analysis and principal component analysis (PCA) were also performed. The settlement/compression, coefficient of variation and PCA results indicated the most intense rate of biodegradation in the top layer. The PCA results of intermediate and bottom levels presented fewer physicochemical and meteorological variables correlated with compression data in contrast with the top layer. It is possible to conclude that environmental conditions may influence internal indicators of MSW biodegradation, such as the settlement.

AB - The authors used a conditional accuracy function (CAF) method to compute the mean accuracy of multiple reaction time ranges, to investigate the association between aerobic fitness and the utilization of cognitive control strategy during preadolescence. Thirty-eight higher- and lower-fit children were grouped according to their cardiorespiratory capacity (VO2max) and completed a modified flanker task. Seventeen young adults were recruited as a reference group of maturation. The results showed that higher-fit children exhibited an adult-like performance pattern, and demonstrated increased overall response accuracy compared to lower-fit children, with a disproportionally larger increase in individual responses when the time allowed for discriminative processing was constrained. These findings suggest that aerobic fitness is associated with enhanced cognitive control and development of a more proactive control strategy during flanker task in preadolescent children.

AB - Controlled release (CR) nano-formulations of Mancozeb (manganese-zinc double salt of N,N-bisdithiocarbamic acid), a protective fungicide, have been prepared using laboratory-synthesized poly(ethylene glycols) (PEGs)-based functionalized amphiphilic copolymers without using any surfactants or external additives. The release kinetics of the developed Mancozeb CR formulations were studied and compared with that of commercially available 42% suspension concentrate and 75% wettable powder. Maximum amount of Mancozeb was released on 42nd day for PEG-600 and octyl chain, PEG-1000 and octyl chain, and PEG-600 and hexadecyl chain, on 35th day for PEG-1000 and hexadecyl chain, on 28th day for PEG-1500 and octyl chain, PEG-2000 and octyl chain, PEG-1500 and hexadecyl chain, and PEG-2000 and hexadecyl chain in comparison to both commercial formulations (15th day). The diffusion exponent (n value) of Mancozeb in water ranged from 0.42 to 0.62 in tested formulations. The half-release (t1/2) values ranged from 17.35 to 35.14 days, and the period of optimum availability of Mancozeb ranged from 18.54 to 35.42 days. Further, the in vitro bioefficacy evaluation of developed formulations was done against plant pathogenic fungi Alternaria solani and Sclerotium rolfsii by poison food technique. Effective dose for 50% inhibition in mgL-1 (ED50) values of developed formulations varied from 1.31 to 2.79 mg L-1 for A. solani, and 1.60 to 3.14 mg L-1 for S. rolfsii. The present methodology is simple, economical, and eco-friendly for the development of environment-friendly CR formulations of Mancozeb. These formulations can be used to optimize the release of Mancozeb to achieve disease control for the desired period depending upon the matrix of the polymer used. Importantly, the maximum amount of active ingredient remains available for a reasonable period after application. In addition, the developed CR formulations were found to be suitable for fungicidal applications, allowing use of Mancozeb in lower doses. PMID- 27715501 TI - Putative RNA-Directed Adaptive Mutations in Cancer Evolution. AB - Understanding the molecular mechanisms behind the capacity of cancer cells to adapt to the tumor microenvironment and to anticancer therapies is a major challenge. In this context, cancer is believed to be an evolutionary process where random mutations and the selection process shape the mutational pattern and phenotype of cancer cells. This article challenges the notion of randomness of some cancer-associated mutations by describing molecular mechanisms involving stress-mediated biogenesis of mRNA-derived small RNAs able to target and increase the local mutation rate of the genomic loci they originate from. It is proposed that the probability of some mutations at specific loci could be increased in a stress-specific and RNA-depending manner. This would increase the probability of generating mutations that could alleviate stress situations, such as those triggered by anticancer drugs. Such a mechanism is made possible because tumor- and anticancer drug-associated stress situations trigger both cellular reprogramming and inflammation, which leads cancer cells to express molecular tools allowing them to "attack" and mutate their own genome in an RNA-directed manner. PMID- 27715604 TI - Impact of single anaerobic exercise on delayed activation of endothelial xanthine oxidase in men and women. AB - OBJECTIVES: The aim of the study was to evaluate the activity of xanthine oxidase (XO) in the blood of men and women during the first hour following a single anaerobic exercise (AN-EX), and after 24 hours of recovery, and to determine whether the changes in XO activity in the blood after AN-EX are dependent on anaerobic performance. METHODS: Ten men and ten women performed a single AN-EX. Blood was collected before and five times after completion of the AN-EX. The activity of XO was determined. RESULTS: In both groups, a significant (P < 0.05) increase in blood XO activity was found only 24 hours after the AN-EX. The increased activity of XO in men was significantly lower than in women (P < 0.05). Negative correlations were found between the increase in XO activity in the blood plasma 24 hours after the AN-EX and anaerobic power, the total work performed during the AN-EX and the power decrease. DISCUSSION: In the first hour after the single AN-EX, XO activity in the blood of women and men did not change, but after 24 hours of recovery, it was significantly higher compared to baseline levels in both sexes. Single AN-EX causes a smaller increase in XO activity in people with higher anaerobic performance.

AB - The Anaerobic Digestion Model No. 1 (ADM1) was extended to include lactate, a crucial metabolic product during sugar fermentation. This study tests the validity of the modified ADM1 model in improving the predictions of a standard biogas reactor. This reactor was prepared in the laboratory with simple organic substrates with an intention to represent an 'average biogas plant'. Kinetic parameters were determined from a lactic acid enriched steady-state reactor. The parameters were adjusted further in order to acquire satisfying simulation results systematically with the batch experiments and then against the standard biogas reactor. Arresting methanogenesis revealed that lactate degradation occurred majorly via acetate followed by propionate, and a non-negligible proportion of butyrate too was found, which were further updated in the model. The modified ADM1 provided a successful correlation with the experimental results for the batch and continuous experiments. We justified that inclusion of lactate in the model resulted in optimized simulation for both biogas and methane content in the standard biogas reactor.

AB - Although the relationship between negative childhood experiences, peer victimization, depressive symptoms, and Non-Suicidal Self-Injury (NSSI) is widely recognized, the mechanisms involved are not fully understood, especially among adolescents. This study aims to test the mediating role of both self-criticism and depressive symptoms in the relationship between memories of negative or positive experiences, current peer victimization, and NSSI. The sample consists 854 Portuguese adolescents, 451 female and 403 male, with ages between 12 and 18 years (M = 14.89; SD = 1.79), from middle and secondary schools. Participants answered self-report measures. Results from path analysis showed that memories of negative experiences, the absence of positive memories with family in childhood and peer victimization indirectly impact on NSSI through self-criticism and depressive symptoms. In addition, these stressful experiences led to depressive symptoms through self-criticism. Lastly, the most severe form of self-criticism indirectly impacts on NSSI through depressive symptoms, even though it also has a strong direct effect. It suggests that negative experiences with parents and peer victimization, as well as the absence of positive memories with family, have a negative impact on NSSI when these experiences are linked with a sense of self hatred and depressive symptoms. PMID- 27715607 TI - Development and validation of the Chinese Death Metaphors Scale-Revised. AB - Chinese people tend to use metaphorical expressions and rhetorical figures to convey meanings and emotions, and they usually talk about death implicitly. The assessment of death metaphors and images can provide a better understanding of Chinese personal perceptions of death. This study aimed at modifying the Chinese Death Metaphors Scale (CDMS; Cheung, 2005 ) and establishing one that is more suitable for Chinese people. Thirty-one death metaphor statements in Chinese were created from items of CDMS and an open questionnaire study. The item pool was tested with 425 participants and exploratory factor analysis revealed four factors (Comfortable/Painful/Sorrowful/Empty), differing with the two-factor structure (Positive/Negative) of the original CDMS. On the basis of this, a 24 item Revised Chinese Death Metaphors Scale was generated. It was carried out to 473 participants together with Templer's Death Anxiety Scale (DAS) for Confirmatory factor analysis, which revealed an acceptable model fit: chi2/df = 4.05, goodness-of-fit index = .85, adjusted goodness-of-fit index = .82, incremental fit index = .90, nonnormed fit index = .90, comparative fit index = .90, root mean square error of approximation = .08, all met the criteria standards for adequacy of fit. Construct validity, criterion-related validity with DAS, and composite reliability were all acceptable and reasonable. The Chinese Death Metaphors Scale-Revised is satisfactory and reliable and more suitable than previous instruments for use with Chinese people. PMID- 27715650 TI - App Factory: A flexible approach to rehabilitation engineering in an era of rapid technology advancement. AB - This article describes a flexible and effective approach to research and development in an era of rapid technological advancement. The approach relies on secondary dispersal of grant funds to commercial developers through a competitive selection process. This "App Factory" model balances the practical reliance on multi-year funding needed to sustain a rehabilitation engineering research center (RERC), with the need for agility and adaptability of development efforts undertaken in a rapidly changing technology environment. This approach also allows us to take advantage of technical expertise needed to accomplish a particular development task, and provides incentives to deliver successful products in a cost-effective manner. In this article, we describe the App Factory structure, process, and results achieved to date; and we discuss the lessons learned and the potential relevance of this approach for other grant-funded research and development efforts. Data presented on the direct costs and number of downloads of the 16 app development projects funded in the App Factory's first 3 years show that it can be an effective means for supporting focused, short-term assistive technology development projects. PMID- 27715651 TI - 1H-NMR-based metabolomic study on toxicity of methomyl and methidathion in fish. AB - A 1H-nuclear magnetic resonance (NMR) spectroscopy with multivariate analysis was applied to detect the toxicity of antiacetylcholinesterase insecticides, methomyl (methyl (1E)-N-(methylcarbamoyloxy)ethanimidothioate) and methidathion (3 (dimethoxyphosphinothioyl sulfanylmethyl)-5-methoxy-1,3,4-thiadiazol-2-one), using zebrafish (Danio rerio) and Chinese bleak (Aphyocypris chinensis). Generally, methomyl and methidathion have been believed not to highly accumulate in fish tissues. However, these pesticides showed their toxicity by altering patterns of whole-body metabolites in neurotransmitter balance, energy metabolism, oxidative stress, and muscle maintenance in low concentrations. We used Pearson correlation analysis to contextualize the metabolic markers in pesticide treated groups. We observed that the positive correlations of choline with acetate and betaine in untreated control were shifted to null correlations showing acetylcholinesterase specific toxicity. This research demonstrated the applicability and potential of NMR metabolomics in detecting toxic effects of insecticide with a modicum of concentrations in aquatic environment. PMID- 27715652 TI - The effect of body armor on saving officers' lives: An analysis using LEOKA data. AB - Using the Law Enforcement Officers Killed and Assaulted (LEOKA; 2002-2011) database, we examined the life-saving effectiveness of body armor while adjusting for a range of confounders not assessed in previous studies. Among the 637 officers who were shot by a firearm at the torso, those who wore body armor were 76% less likely to be killed than those who did not wear armor, controlling for an array of individual and incident characteristics. A number of factors influenced officers' armor wearing behavior include age, BMI, rank, geographic region, and type of assignment. Results will inform law enforcement agencies in assessing gaps in their current policy and help focus limited resources to encourage armor wearing. The investigation of other factors that influence police officers' chance of surviving a gun shooting (while controlling for body armor) will also have important implications for policies related to sending backup officers to police shootings, emergency response, and other critical areas. PMID- 27715653 TI - The effect of obesity on postural stability during a standardized lifting task. AB - The objective of this study was to assess the effect of obesity on postural stability during a standardized lifting task. Twelve young males, six obese and six non-obese, completed three replications of repeated six lifts (at a rate of six lifts per minutes) at two levels of loads (10% and 25% of capacity) crossed with two levels of orientation (0 degrees and 45 degrees from sagittal plane). Postural stability measures showed that center of pressure sway path and sway area were ~21% and ~53% lower with obesity, respectively. Additionally, frequency band of amplitude spectrum in the medial lateral direction at 0 degrees lifting orientation was significantly lower with obesity. The results suggest that obesity, as measured by body mass index, does not impair balance control in healthy young males when lifting load is relative to the capacity. PMID- 27715654 TI - A brief review on recent developments of electrochemical sensors in environmental application for PGMs. AB - This study offers a brief review of the latest developments and applications of electrochemical sensors for the detection of Platinum Group Metals (PGMs) using electrochemical sensors. In particular, significant advances in electrochemical sensors made over the past decade and sensing methodologies associated with the introduction of nanostructures are highlighted. Amongst a variety of detection methods that have been developed for PGMs, nanoparticles offer the unrivaled merits of high sensitivity. Rapid detection of PGMs is a key step to promote improvement of the public health and individual quality of life. Conventional methods to detect PGMs rely on time-consuming and labor intensive procedures such as extraction, isolation, enrichment, counting, etc., prior to measurement. This results in laborious sample preparation and testing over several days. This study reviewed the state-of-the-art application of nanoparticles (NPs) in electrochemical analysis of environmental pollutants. This review is intended to provide environmental scientists and engineers an overview of current rapid detection methods, a close look at the nanoparticles based electrodes and identification of knowledge gaps and future research needs. We summarize electrodes that have been used in the past for detection of PGMs. We describe several examples of applications in environmental electrochemical sensors and performance in terms of sensitivity and selectivity for all the sensors utilized for PGMs detection. NPs have promising potential to increase competitiveness of electrochemical sensors in environmental monitoring, though this review has focused mainly on sensors used in the past decade for PGMs detection. This review therefore provides a synthesis of outstanding performances in recent advances in the nanosensor application for PGMs determination. PMID- 27715655 TI - Thin-Section CT Features of Idiopathic Pulmonary Fibrosis Correlated with Micro CT and Histologic Analysis. AB - Purpose To elucidate the underlying lung changes responsible for the computed tomographic (CT) features of idiopathic pulmonary fibrosis (IPF) and to gain insight into the way IPF proceeds through the lungs and progresses over time. Materials and Methods Micro-CT studies of tissue cores obtained from explant lungs were examined and were correlated 1:1 with a CT study obtained immediately before transplantation. Samples for histologic analysis were obtained from selected cores. Results In areas with no or minimal abnormalities on CT images, small areas of increased attenuation located in or near the interlobular septa can be seen on micro-CT studies. In more involved lung areas, the number of opacities increases and opacities enlarge and approach each other along the interlobular septa, causing a fine reticular pattern on CT images. Simultaneously, air-containing structures in and around these opacities arise, corresponding with small cysts on CT images. Honeycombing is caused by a progressive increase in the number and size of these cystic structures and tissue opacities that gradually extend toward the centrilobular region and finally replace the entire lobule. At histologic analysis, the small islands of increased attenuation very likely correspond with fibroblastic foci. Near these fibroblastic foci, an abnormal adjacency of alveolar walls was seen, suggesting alveolar collapse. In later stages, normal lung tissue is replaced by a large amount of young collagen, as seen in patients with advanced fibrosis. Conclusion Fibrosis and cyst formation in patients with IPF seem to start at the periphery of the pulmonary lobule and progressively extend toward the core of this anatomic lung unit. Evidence was found that alveolar collapse might already be present in an early stage when there is only little pulmonary fibrosis. (c) RSNA, 2016. PMID- 27715656 TI - Preoperative MR Imaging in Women with Breast Cancer Detected at Screening US. AB - Purpose To determine additional cancer yield of magnetic resonance (MR) imaging in women with breast cancer detected at screening ultrasonography (US) and to identify a subgroup of women who are likely to benefit from preoperative MR imaging. Materials and Methods This study was approved by the institutional review board, and the requirement for informed consent was waived. A retrospective review of 374 women (median age, 48 years; age range, 30-74 years) with breast cancer detected at screening US (invasive, n = 321) who underwent preoperative breast MR imaging between 2007 and 2013 was performed. Cancer yield and positive predictive value of biopsy were calculated. Multivariate logistic regression analysis was performed to identify clinical-pathologic features associated with additional cancer detected at MR imaging. Results Of 374 women, 21 (5.6%; 95% confidence interval [CI]: 3.5%, 8.5%) were diagnosed with additional cancer (positive predictive value of biopsy, 42.0% [21 of 50 women]; 95% CI: 28%, 57%). Index invasive lobular cancer (ILC) histologic type was significantly associated with additional cancer detected at MR imaging (odds ratio, 4.0; 95% CI: 1.2, 13.6; P = .03). In women with index invasive cancer, premenopausal status (odds ratio, 5.7; 95% CI: 1.2, 35.8; P = .03) and lobular histologic type (odds ratio, 3.9; 95% CI: 1.1, 12.3; P = .03) were factors associated with additional cancer detected at MR imaging. Conclusion Preoperative MR imaging helped to detect additional sites of cancer in 5.6% of women with breast cancer detected at screening US. Women with index ILC and premenopausal women are more likely to benefit from preoperative MR imaging. (c) RSNA, 2016 Online supplemental material is available for this article.

PMID- 27715657 TI - Self-gated Non-Contrast-enhanced Functional Lung MR Imaging for Quantitative Ventilation Assessment in Patients with Cystic Fibrosis. AB - Purpose To assess the clinical feasibility of self-gated non-contrast-enhanced functional lung (SENCEFUL) magnetic resonance (MR) imaging for quantitative ventilation (QV) imaging in patients with cystic fibrosis (CF). Materials and Methods Twenty patients with CF and 20 matched healthy volunteers underwent functional 1.5-T lung MR imaging with the SENCEFUL imaging approach, in which a two-dimensional fast low-angle shot sequence is used with quasi-random sampling. The lungs were manually segmented on the ventilation-weighted images to obtain QV measurements, which were compared between groups. QV values of the patients were correlated with results of pulmonary function testing. Three radiologists rated the images for presence of ventilation deficits by means of visual inspection. Mann-Whitney U tests, receiver operating characteristic analyses, Spearman correlations, and Gwet agreement coefficient analyses were used for statistical analysis. Results QV of the entire lungs was lower for patients with CF than for control subjects (mean +/- standard deviation, 0.09 mL/mL +/- 0.03 vs 0.11 mL/mL +/- 0.03, respectively; P = .007). QV ratios of upper to lower lung halves were lower in patients with CF than in control subjects (right, 0.84 +/- 0.2 vs 1.16 +/- 0.2, respectively [P < .001]; left, 0.88 +/- 0.3 vs 1.11 +/- 0.1, respectively [P = .017]). Accordingly, ventilation differences between the groups were larger in the upper halves (Delta = 0.04 mL/mL, P <= .001-.002). QV values of patients with CF correlated with forced vital capacity (r = 0.7; 95% confidence interval [CI]: 0.21, 0.91), residual volume (static hyperinflation, r = -0.8; 95% CI: -0.94, 0.42), and forced expiratory volume in 1 second (airway obstruction, r = 0.7; 95% CI: 0.21, 0.91). Disseminated small ventilation deficits were the most frequent involvement pattern, present in 40% of the functional maps in CF versus 8% in the control subjects (P < .001). Conclusion SENCEFUL MR imaging is feasible for QV assessment. Less QV, especially in upper lung parts, and correlation to vital capacity and to markers for hyperinflation and airway obstruction were found in patients with CF. (c) RSNA, 2016. PMID- 27715659 TI - Is There a Correlation Between Static and Dynamic Postural Balance Among Young Male and Female Dancers? AB - Aimed to investigate whether young male and female dancers have different patterns of association between static and dynamic postural balance (PB), 60 dancers from the Australian Ballet School (14-19 years old) were tested for static and dynamic PB with head and lumbar accelerometers. Monotonic relationships between static and dynamic PB were found in head movements among young female dancers in all three directions, but were found for young male dancers in the mediolateral (ML) and anteroposterior (AP) directions only. In lumbar movements, monotonic relationships were found for young female dancers in the AP direction only. Comparing head with lumbar movements in static PB, young male dancers demonstrated monotonic relationships between head and lumbar movements in all 3 directions; however, young female dancers demonstrated monotonic relationships in the AP direction only. In the dynamic measurements, both male and female dancers demonstrated monotonic relationships between head and lumbar movements for all parameters measured in the ML and vertical directions (p < .05). In conclusions, among female dancers static PB ability is correlated with their dynamic ability, whereas among male dancers, no relationship between the static and dynamic PB in the AP direction exists. Male dancers showed head and lumbar coordination in the static PB movement, but both genders manifested no head and lumbar coordination in the AP direction measured for dynamic PB. PMID- 27715709 TI - Acute effects of synthetic cannabinoids: Update 2015. AB - BACKGROUND: Cannabis is the most widely used illicit drug in the United States and Europe. In recent years, a range of new substances with cannabis-like effects known as synthetic cannabinoids (SCs)-have suddenly burst on the drug scene. However, there is limited information about the clinical hazards linked to the use of these emerging substances. This review summarizes the literature to date relating the health effects of SCs. METHOD: A systematic literature review of original case studies was performed using PubMed and Web of Science (January 1980 July 2015). Only articles in which a drug screening was reported were included in this review. RESULTS: Forty-six articles meeting the inclusion criteria were included in this review, reporting data on 114 patients who went to hospital emergency departments after exposure to SCs. The majority of patients were adolescent or young adult males (14-25 years; 24.5 +/- 10.1 years). The most common route of administration was smoking. The SCs most involved were John William Huffman (JWH) derivatives, followed by XRL-11, ADB-PINACA, AM-2201, MAM 2201, and 5F-PB-22. This analysis showed that the use of these substances may cause minor and moderate side effects similar to those of cannabis intoxication, including tachycardia, nausea, somnolence, hallucinations, paranoia, xerostomia, and injected conjunctivae among others. However, atypical cannabis intoxication effects and worse complications (such as renal injuries, aggressiveness, cerebral ischemia, myocardial infarction, etc.) were also observed, which led to a significant morbidity were also observed. Some SCs were highlighted as being involved in 24 cases of deaths. CONCLUSIONS: In this review, the nature and frequency of the signs and symptoms of SC poisoning were estimated in order to inform health professionals about the health risks of these new and emerging substances. PMID- 27715710 TI - System Justification's Opposite Effects on Psychological Well-Being: Testing a Moderated Mediation Model in a Gay Men and Lesbian Sample in Chile. AB - Those who adhere to system justifying beliefs benefit from a palliative function that buffers negative effects on psychological well-being. This has been consistently observed for high-status groups, whereas for members of low-status groups, it remains rather unclear whether system justification exerts a positive or a negative effect. This study tested the palliative effect of system justification on symptoms of anxiety-depression in a gay men and lesbian sample (N = 467) in Chile. Results from moderated mediation analyses revealed that system justification beliefs buffer symptoms of anxiety and depression. However, system justification enhances anxious and depressive symptoms through internalized homonegativity; this mediation effect was significant for gay men. We pose that justifying the social order comprises two contradictory functions: system justification as a coping source, and otherwise, as source of distress under conditions of in-group derogation, posing a threat to well-being among members of low-status groups (as observed in gay and lesbian individuals). Implications of the opposing effects, and gender differences are further discussed in this study. PMID- 27715711 TI - Strategies to Increase Cancer Detection: Review of True-Positive and False Negative Results at Digital Breast Tomosynthesis Screening. AB - Digital breast tomosynthesis (DBT) represents a valuable addition to breast cancer screening by decreasing recall rates while increasing cancer detection rates. The increased accuracy achieved with DBT is due to the quasi-three dimensional format of the reconstructed images and the ability to "scroll through" breast tissue in the reconstructed images, thereby reducing the effect of tissue superimposition found with conventional planar digital mammography. The margins of both benign and malignant lesions are more conspicuous at DBT, which allows improved lesion characterization, increased reader confidence, and improved screening outcomes. However, even with the improvements in accuracy achieved with DBT, there remain differences in breast cancer conspicuity by mammographic view. Early data suggest that breast cancers may be more conspicuous on craniocaudal (CC) views than on mediolateral oblique (MLO) views. While some very laterally located breast cancers may be visualized on only the MLO view, the increased conspicuity of cancers on the CC view compared with the MLO view suggests that DBT screening should be performed with two-view imaging. Even with the improved conspicuity of lesions at DBT, there may still be false-negative studies. Subtle lesions seen on only one view may be discounted, and dense and/or complex tissue patterns may make some cancers occult or extremely difficult to detect. Therefore, radiologists should be cognizant of both perceptual and cognitive errors to avoid potential pitfalls in lesion detection and characterization.

PMID- 27715712 TI - US of the Inguinal Canal: Comprehensive Review of Pathologic Processes with CT and MR Imaging Correlation. AB - Ultrasonography (US) has a fundamental role in the initial examination of patients who present with symptoms indicating abnormalities of the inguinal canal (IC), an area known for its complex anatomy. A thorough understanding of the embryologic and imaging characteristics of the contents of the IC is essential for any general radiologist. Moreover, an awareness of the various pathologic conditions that can affect IC structures is crucial to preventing misdiagnoses and ensuring optimal patient care. Early detection of IC abnormalities can reduce the risk of morbidity and mortality and facilitate proper treatment. Abnormalities may be related to increased intra-abdominal pressure, which can result in development of direct inguinal hernias and varicoceles, or to congenital anomalies of the processus vaginalis, which can result in development of indirect hernias and hydroceles. US is also helpful in assessing postoperative complications of hernia repair, such as hematoma, seroma, abscess, and hernia recurrence. In addition, it is often the modality initially used to detect neoplasms arising from or invading the IC. US is an important tool in the examination of patients suspected of having undescended testes or posttraumatic testicular retraction and is essential for the examination of patients suspected of having torsion or infectious inflammatory conditions of the spermatic cord.

AB - The purpose of this study was to examine the potential effect of child race and interviewer race on forensic interviewing outcomes. The results of the regression analysis indicated that child race and interviewer race had a significant effect on interview outcome category (no findings, inconclusive, or findings consistent with sexual abuse). Furthermore, the results indicate that the interaction of child and interviewer race had predictive value for rates of findings consistent with sexual abuse but not in the direction predicted. Cross-race dyads had significantly higher rates of interview outcomes consistent with sexual abuse. These findings suggest that more research into the effect of race on disclosure of child sexual abuse is needed. PMID- 27715714 TI - Law enforcement attitudes towards naloxone following opioid overdose training. AB - BACKGROUND: Opioid intoxication and overdoses are life-threatening emergencies requiring rapid treatment. One response to this has been to train law enforcement to detect the signs of an opioid overdose and train them to administer naloxone to reverse the effects. Although not a new concept, few studies have attempted to examine this policy. METHODS: At 4 different locations in Indiana, law enforcement personnel were trained to detect the signs of an opioid-related overdose and how to administer naloxone to reverse the effects of the overdose. Pre and post surveys were administered at each location (N = 97). To examine changes in attitudes following training, the authors included items from the Opioid Overdose Attitudes Scale (OOAS), which measures respondents' competency, concerns, and readiness to administer naloxone. RESULTS: Among the full sample, naloxone training resulted in significant increases in competency, concerns, and readiness. Examining changes in attitudes by each location revealed that the training had the greatest effect on competency to administer naloxone and in easing concerns that law enforcement personal might have in administering naloxone. CONCLUSIONS: This study adds to others in showing that law enforcement personnel are receptive to naloxone training and that the OOAS is able to capture these attitudes. This study advances this literature by examining pre-post changes across multiple locations. As the distribution of naloxone continues to proliferate, this study and the OOAS may be valuable towards the development of an evidence-based training model for law enforcement. PMID- 27715716 TI - Pupil Diameter May Reflect Motor Control and Learning. AB - Non-luminance-mediated changes in pupil diameter have been used since the first studies by Darwin in 1872 as indicators of clinical, cognitive, and arousal states. However, the relation between processes involved in motor control and changes in pupil diameter remains largely unknown. Twenty participants attempted to compensate random walks of a cursor with a computer mouse to restrain its trajectory within a target circle while the authors recorded their pupil diameters. Two conditions allowed the authors to experimentally manipulate the motor and cognitive components of the task. First, the step size of the cursor's random walk was either large or small leading to 2 task difficulties (difficult or easy). Second, they instructed participants to imagine controlling the cursor by moving the mouse, but without actually moving it (task modality: imagined movement or real movement condition). Task difficulty and modality allowed the authors to show that pupil diameters reflect processes involved in motor control and in the processing of feedback, respectively. Furthermore, the authors also demonstrate that motor learning can be quantified by pupil size. This noninvasive approach provides a promising method for investigating not only motor control, but also motor imagery, a research field of growing importance in sports and rehabilitation. PMID- 27715715 TI - Comparison between active (pumped) and passive (diffusive) sampling methods for formaldehyde in pathology and histology laboratories. AB - This study was to determine occupational exposures to formaldehyde and to compare concentrations of formaldehyde obtained by active and passive sampling methods. In one pathology and one histology laboratories, exposure measurements were collected with sets of active air samplers (Supelco LpDNPH tubes) and passive badges (ChemDisk Aldehyde Monitor 571). Sixty-six sample pairs (49 personal and 17 area) were collected and analyzed by NIOSH NMAM 2016 for active samples and OSHA Method 1007 (using the manufacturer's updated uptake rate) for passive samples. All active and passive 8-hr time-weighted average (TWA) measurements showed compliance with the OSHA permissible exposure limit (PEL-0.75 ppm) except for one passive measurement, whereas 78% for the active and 88% for the passive samples exceeded the NIOSH recommended exposure limit (REL-0.016 ppm). Overall, 73% of the passive samples showed higher concentrations than the active samples and a statistical test indicated disagreement between two methods for all data and for data without outliers. The OSHA Method cautions that passive samplers should not be used for sampling situations involving formalin solutions because of low concentration estimates in the presence of reaction products of formaldehyde and methanol (a formalin additive). However, this situation was not observed, perhaps because the formalin solutions used in these laboratories included much less methanol (3%) than those tested in the OSHA Method (up to 15%). The passive samplers in general overestimated concentrations compared to the active method, which is prudent for demonstrating compliance with an occupational exposure limit, but occasional large differences may be a result of collecting aerosolized droplets or splashes on the face of the samplers. In the situations examined in this study the passive sampler generally produces higher results than the active sampler so that a body of results from passive samplers demonstrating compliance with the OSHA PEL would be a valid conclusion. However, individual passive samples can show lower results than a paired active sampler so that a single result should be treated with caution.

PMID- 27715771 TI - Surviving Violence in Everyday Life: A Communicative Approach to Homelessness. AB - In this narrative review, the author synthesizes the literature on homelessness across various disciplines (e.g., public health, social work, sociology, and communication) to demonstrate how the experiences of homelessness can be created, maintained, and reinforced through communication, including interpersonal interactions and public discourse. By conceptualizing homelessness as a culturally constructed and socially situated phenomenon, the author examines (a) the complex conceptualization of homelessness, (b) everyday violence faced by people who are homeless, and (c) coping strategies of people who are homeless. In summary, homelessness is a complex social phenomenon, involving tensions between individuals, families, and social systems, all of which are situated in the larger sociocultural and sociopolitical contexts of a specific time and place. PMID- 27715830 TI - Validation Study of the Revised Version of the Scale of Prejudice against Sexual and Gender Diversity in Brazil. AB - In Brazil, there is a deficit of culturally adapted tools to assess prejudice against sexual and gender diversity with empirically demonstrable validity and reliability. Prejudice against non-heterosexual orientations is a strong problem within Brazilian culture and is particularly related to non-normative expressions of gender. To address these issues, a scale was created. The objective of this article is to validate the revised version of this instrument developed for the specificities of Brazilian culture and establish its reliability. Eight thousand, one hundred and eighty-four undergraduate students from southern Brazil completed the revised version of Scale of Prejudice Against Sexual and Gender Diversity (PASGD). Analysis was conducted using Item Response Theory (IRT) model for rating scale data, criterion validity and confirmatory factor analysis (CFA). The scale showed good validity and reliability. The results indicate that the PASGD is a useful tool for assessing prejudice in the Brazilian context, adapted for the local Brazilian reality. PMID- 27715772 TI - Identity reconstruction among older cancer survivors: Age and meaning in the context of a life-altering illness. AB - This article evaluates how older cancer patients describe cancer survivorship and incorporate the cancer experience into long-term evaluations of health. From a series of 53 qualitative interviews with adults with histories of breast and prostate cancers and non-Hodgkin's lymphoma, we analyzed age-related discussions among those 65 and older (n = 21). Emergent themes revealed the: (1) historical conceptualization of cancer, (2) changed perspective following diagnosis, (3) cancer in the context of a long biography, (4) cancer in the context of the aging body and decline, and (5) meaning of time remaining and quality of life. One important suggestion from our work, relevant to all clinicians regardless of specialty or role, is to incorporate goals for the future into individualized survivor care plans for older survivors. PMID- 27715903 TI - Older women's negative psychological and physical experiences with injectable cosmetic treatments to the face. AB - Seven women (43 to 64 years old) who had negative or mixed emotions about having Botox and/or facial filler injections to the face to reduce signs of aging were interviewed about the impact of the procedures. Impacts ranged from disappointment to all-encompassing, lingering physical and psychological effects, and some women felt abandoned by the medical industrial complex when they turned to it for help with their symptoms. A feminist phenomenological analysis focused on corporeal, temporal, and relational existential modes of being. We describe their bodily experiences as (a) commodified, (b) fractured, PMID- 27716015 TI - Rotational vertebrobasilar insufficiency due to compression of a persistent first intersegmental vertebral artery variant: case report. AB - Rotational vertebrobasilar insufficiency, or bow hunter's syndrome, is a rare cause of posterior circulation ischemia, which, following rotation of the head, results in episodic vertigo, dizziness, nystagmus, or syncope. While typically caused by dynamic occlusion of the vertebral artery in its V2 and V3 segments, the authors here describe a patient with dynamic occlusion of the vertebral artery secondary to a persistent first intersegmental artery, a rare variant course of the vertebral artery. In this case the vertebral artery coursed under rather than over the posterior arch of the C-1. This patient was also found to have incomplete development of the posterior arch of C-1, as is often seen with this variant. The patient underwent dynamic digital subtraction angiography, which demonstrated occlusion at the variant vertebral artery with head turning. He was then taken for decompression of the vertebral artery through removal of the incomplete arch of C-1 that was causing the dynamic compression. After surgery the patient had a complete resolution of symptoms. In this report, the authors present the details of this case, describe the anatomical variants involved, and provide a discussion regarding the need for atlantoaxial fusion in these patients. PMID- 27715904 TI - Recent incarceration and buprenorphine maintenance treatment outcomes among human immunodeficiency virus-positive patients. AB - BACKGROUND: Opioid use disorder is a common cause of morbidity and mortality among people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Buprenorphine maintenance treatment (BMT) is an effective means of therapy, but patients with recent criminal justice involvement may need more support during BMT than other patients. The authors hypothesized that recently incarcerated BMT patients who initiated treatment in primary care would have poorer treatment outcomes than those who were not recently incarcerated. METHODS: Investigators analyzed data from a multisite cohort study of BMT integrated into HIV care. Patients were stratified by self-reported incarceration in the 30 days before initiation of BMT. The outcomes of interest were 6- and 12 month treatment retention and self-reported opioid use. Investigators used multivariable logistic regression and hierarchical linear model, respectively, to evaluate the association between recent incarceration and these outcomes while adjusting for potential confounding variables. RESULTS: Among 305 BMT patients living with HIV/AIDS, 39 (13%) reported recent incarceration. Patients with recent incarceration (vs. without) were more likely to be homeless, unemployed, and previously diagnosed with mental illness. Recent incarceration was not significantly associated with differences in 6-month (odds ratio [OR] = 0.95; 95% confidence interval [CI] = 0.46-1.98) and 12-month (OR = 0.57; 95% CI = 0.27 1.18) treatment retention or in self-reported opioid use (OR = 0.99; 95% CI = 0.51-1.92) after adjustment for potential confounding variables. CONCLUSIONS: Those with incarceration in the 30 days prior to BMT initiation were more likely to be homeless, unemployed, and previously diagnosed with mental illness than those without recent incarceration. However, no significant difference in self reported opioid use or 6-month or 12-month retention in treatment was detected between those with and without recent incarceration. Future studies should confirm these findings with larger sample sizes. Encouraging formerly incarcerated individuals with opioid use disorder to initiate evidence-based treatments, including BMT, should be part of efforts to confront the opioid addiction epidemic in the United States. PMID- 27716016 TI - Posterior corrective surgery with a multilevel transforaminal lumbar interbody fusion and a rod rotation maneuver for patients with degenerative lumbar kyphoscoliosis. AB - The purpose of this study was to assess the clinical results of posterior corrective surgery using a multilevel transforaminal lumbar interbody fusion (TLIF) with a rod rotation (RR) and to evaluate the segmental corrective effect of a TLIF using CT imaging. The medical records of 15 consecutive patients with degenerative lumbar kyphoscoliosis (DLKS) who had undergone posterior spinal corrective surgery using a multilevel TLIF with an RR technique and who had a minimum follow-up of 2 years were retrospectively reviewed. Radiographic parameters were evaluated using plain radiographs, and segmental correction was evaluated using CT imaging. Clinical outcomes were evaluated with the Scoliosis Research Society Patient Questionnaire-22 (SRS-22) and the SF-36. The mean follow up period was 46.7 months, and the mean age at the time of surgery was 60.7 years. The mean total SRS-22 score was 2.9 before surgery and significantly improved to 4.0 at the latest follow-up. The physical functioning, role functioning (physical), and social functioning subcategories of the SF-36 were generally improved at the latest follow-up, although the changes in these scores were not statistically significant. The bodily pain, vitality, and mental health subcategories were significantly improved at the latest follow-up (p < 0.05). Three complications occurred in 3 patients (20%). The Cobb angle of the lumbar curve was reduced to 20.3 degrees after surgery. The overall correction rate was 66.4%. The pelvic incidence-lumbar lordosis (preoperative/postoperative = 31.5 degrees /4.3 degrees ), pelvic tilt (29.2 degrees /18.9 degrees ), and sagittal vertical axis (78.3/27.6 mm) were improved after surgery and remained so throughout the follow-up. Computed tomography image analysis suggested that a 1 level TLIF can result in 10.9 degrees of scoliosis correction and 6.8 degrees of lordosis. Posterior corrective surgery using a multilevel TLIF with an RR on patients with DLKS can provide effective correction in the coronal plane but allows only limited sagittal correction. PMID- 27716017 TI - Reconstruction of the C-1 lateral mass with a titanium expandable cage after resection of eosinophilic granuloma in an adult patient. AB - Spinal involvement occurs frequently in cases of eosinophilic granuloma (EG), but surgical treatment is limited primarily to those with spinal instability. Involvement of the cervical spine is rare, but primarily occurs in the vertebral bodies, and is normally amenable to anterior corpectomy and spinal reconstruction. The authors describe a 27-year-old man with pathologically proven EG who presented with complete destruction of the C-1 lateral mass requiring spinal stabilization. A titanium expandable cage was used to reconstruct the weight-bearing column from the occipital condyle to the superior articular surface of C-2 from a posterior approach, with preservation of the traversing vertebral artery. To the authors' knowledge, this is the first reported instance of reconstruction of the C-1 lateral mass using an expandable metal cage, which facilitated preservation of the vertebral artery. PMID- 27716018 TI - Less invasive lumbopelvic fixation technique using a percutaneous pedicle screw system for unstable pelvic ring fracture in a patient with severe multiple traumas. AB - Pelvic ring fractures are defined as life-threatening injuries that can be treated surgically with external or internal fixation. The authors report on an 81-year-old woman with an unstable pelvic fracture accompanying multiple traumas that was successfully treated with a less invasive procedure. The patient was injured in a traffic accident and sustained a total of 20 fractures, including pelvic ring, bilateral rib, and lumbar transverse processes fractures, and multiple fractures of both upper and lower extremities. The pelvic ring fracture was unstable with fractures of the bilateral sacrum with right sacroiliac disruption, right superior and inferior pubic rami, left superior pubic ramus, and ischium. During emergency surgery, bilateral external fixation was applied to the iliac crest to stabilize the pelvic ring. Second and third surgeries were performed 11 and 18 days after the first emergency surgery, respectively, to treat the multiple fractures. At the third surgery, the pelvic ring fracture was stabilized surgically using a less invasive posterior fixation technique. In this technique, 2 iliac screws were inserted on each side following an 8-cm midline posterior incision from the S-1 to S-3 spinous process, with the subcutaneous tissue detached from the fascia of the paraspinal muscles. The S-2 spinous process was removed and 2 rods were connected to bilateral iliac screws to stabilize the bilateral ilium in a switchback fashion. A crosslink device was applied to connect the 2 rods at the base of the S-2 spinous process. Following pelvic fixation, percutaneous pedicle screws were inserted into L-4 and L-5 vertebral bodies on both sides, and connected to the cranial rod connecting the bilateral iliac screws, thus completing the lumbopelvic fixation. The postoperative course was favorable with no postoperative complications. At the 10 month follow-up, bone union had been achieved at the superior ramus of the pubis, the patient did not complain of pain, and her activities of daily life returned to preinjury status. Unstable pelvic ring fractures need to be sufficiently stabilized for good surgical outcome. However, to avoid postoperative complications, a less invasive treatment is preferred, particularly in cases with poor general condition. This procedure is less invasive and provides sufficient stabilization to the unstable pelvic ring fracture, and thus is the ideal surgical procedure for such cases.

AB - Greater longevity in the UK population has led to the increasing diversity of women experiencing aging in a multitude of ways. Internationally, gender inequalities in aging are still relatively invisible within both government policy and everyday life for particular groups of women. This article explores the concept of women growing older "solo"-by which we mean women who find themselves nonpartnered and aging without children as they move into later life. We report on the findings from a mixed-methods survey of 76 solo women in the UK aged 50 years and over, used to provide a broader overview of the issues and challenges they face as they move into later life. Qualitative data from the survey captured respondents' perspectives about the links between their relationships status and well-being in later life and highlighted specific cumulative disadvantages emerging for some women as a result of their solo lifestyles. We discuss two key themes that were identified, "solo-loneliness" and "meaningful futures," in conjunction with the relevant literature and make suggestions for future research within gender and aging studies that could enhance more positive approaches to solo lifestyles. PMID- 27716020 TI - At the threshold of retirement: From all-absorbing relations to self actualization. AB - To investigate the complexities of the retirement process, the present article draws on a case study of Eva, a Swedish woman who "awakened" from all-absorbing relations. It considers the ways in which retirement can enable liberation from patriarchal kinship structures and embodied values of respectability. The aim is to illuminate how deep, embodied values can become conscious and explicit during precarious life situations and transitional phases. The relation between the Swedish welfare state, an I-we balance, and gender equity values are illuminated. These analytical dimensions support the analysis by providing insights into the ways in which individuals embody and use cultural and social structures when they aim to manage unpredictability and to create change toward self-actualization. PMID- 27716021 TI - The experience of high-frequency gambling behavior of older adult females in the United Kingdom: An interpretative phenomenological analysis. AB - The prevalence of older adult female gambling participation and gambling disorder is increasing in the UK, and there is a paucity of published research available to understand possible risk factors for frequent gambling in this demographic. The aim of the current study was to identify and explore motivations and patterns of gambling behavior in high-frequency older adult female gamblers in the UK, from the perspective of the individual and in the context of their experience of aging. Ten UK older adult female high-frequency gamblers were recruited via stratified purposive sampling, with a mean age of 70.4 years. Data was collected via semistructured interviews and analyzed using interpretative phenomenological analysis. Three core themes representative of the experience of this phenomenon emerged from the transcripts, including: Filling voids, emotional escape, and overspending. The present study has provided a contextualized understanding of motivating factors and several age-related vulnerabilities that may account for high gambling frequency in this population. PMID- 27716022 TI - Identification of selective sweeps reveals divergent selection between Chinese Holstein and Simmental cattle populations. AB - BACKGROUND: The identification of signals left by recent positive selection provides a feasible approach for targeting genomic variants that underlie complex traits and fitness. A better understanding of the selection mechanisms that occurred during the evolution of species can also be gained. In this study, we simultaneously detected the genome-wide footprints of recent positive selection that occurred within and between Chinese Holstein and Simmental populations, which have been subjected to artificial selection for distinct purposes. We conducted analyses using various complementary approaches, including LRH, XP-EHH and FST, based on the Illumina 770K high-density single nucleotide polymorphism (SNP) array, to enable more comprehensive detection. RESULTS: We successfully constructed profiles of selective signals in both cattle populations. To further annotate these regions, we identified a set of novel functional genes related to growth, reproduction, immune response and milk production. There were no overlapping candidate windows between the two breeds. Finally, we investigated the distribution of SNPs that had low FST values across five distinct functional regions in the genome. In the low-minor allele frequency bin, we found a higher proportion of low-FST SNPs in the exons of the bovine genome, which indicates strong purifying selection of the exons. CONCLUSIONS: The selection signatures identified in these two populations demonstrated positive selection pressure on a set of important genes with potential functions that are involved in many biological processes. We also demonstrated that in the bovine genome, exons were under strong purifying selection. Our findings provide insight into the mechanisms of artificial selection and will facilitate follow-up functional studies of potential candidate genes that are related to various economically important traits in cattle. PMID- 27716024 TI - Genetic composition of captive panda population. AB - BACKGROUND: A major function of the captive panda population is to preserve the genetic diversity of wild panda populations in their natural habitats. Understanding the genetic composition of the captive panda population in terms of genetic contributions from the wild panda populations provides necessary knowledge for breeding plans to preserve the genetic diversity of the wild panda populations. RESULTS: The genetic contributions from different wild populations to the captive panda population were highly unbalanced, with Qionglai accounting for 52.2 % of the captive panda gene pool, followed by Minshan with 21.5 %, Qinling with 10.6 %, Liangshan with 8.2 %, and Xiaoxiangling with 3.6 %, whereas Daxiangling, which had similar population size as Xiaoxiangling, had no genetic representation in the captive population. The current breeding recommendations may increase the contribution of some small wild populations at the expense of decreasing the contributions of other small wild populations, i.e., increasing the Xiaoxiangling contribution while decreasing the contribution of Liangshan, or sharply increasing the Qinling contribution while decreasing the contributions of Xiaoxiangling and Liangshan, which were two of the three smallest wild populations and were already severely under-represented in the captive population. We developed three habitat-controlled breeding plans that could increase the genetic contributions from the smallest wild populations to 6.7-11.2 % for Xiaoxiangling, 11.5-12.3 % for Liangshan and 12.9-20.0 % for Qinling among the offspring of one breeding season while reducing the risk of hidden inbreeding due to related founders from the same habitat undetectable by pedigree data. CONCLUSION: The three smallest wild panda populations of Daxiangling, Xiaoxiangling and Liangshan either had no representation or were severely unrepresented in the current captive panda population. By incorporating the breeding goal of increasing the genetic contributions from the smallest wild populations into breeding plans, the severely under-represented small wild populations in the current captive panda population could be increased steadily for the near future. PMID- 27716023 TI - Identification of replication-dependent and replication-independent linker histone complexes: Tpr specifically promotes replication-dependent linker histone stability. AB - BACKGROUND: There are 11 variants of linker histone H1 in mammalian cells. Beyond their shared abilities to stabilize and condense chromatin, the H1 variants have been found to have non-redundant functions, the mechanisms of which are not fully understood. Like core histones, there are both replication-dependent and replication-independent linker histone variants. The histone chaperones and other factors that regulate linker histone dynamics in the cell are largely unknown. In particular, it is not known whether replication-dependent and replication independent linker histones interact with distinct or common sets of proteins. To better understand linker histone dynamics and assembly, we used chromatography and mass spectrometry approaches to identify proteins that are associated with replication-dependent and replication-independent H1 variants. We then used a variety of in vivo analyses to validate the functional relevance of identified interactions. RESULTS: We identified proteins that bind to all linker histone variants and proteins that are specific for only one class of variant. The factors identified include histone chaperones, transcriptional regulators, RNA binding proteins and ribosomal proteins. The nuclear pore complex protein Tpr, which was found to associate with only replication-dependent linker histones, specifically promoted their stability. CONCLUSION: Replication-dependent and replication-independent linker histone variants can interact with both common and distinct sets of proteins. Some of these factors are likely to function as histone chaperones while others may suggest novel links between linker histones and RNA metabolism. The nuclear pore complex protein Tpr specifically interacts with histone H1.1 and H1.2 but not H1x and can regulate the stability of these replication-dependent linker histones. PMID- 27716025 TI - On the role of the proventricle region in reproduction and regeneration in Typosyllis antoni (Annelida: Syllidae). AB - BACKGROUND: Syllids are a species rich annelid family possessing remarkable regenerative ability, which is not only the response after traumatic injury, but also a key step during the life cycle of several syllid taxa. In these animals the posterior part of the body becomes an epitoke and is later detached as a distinct unit named stolon. Such a sexual reproductive mode is named schizogamy or stolonization. The prostomium and the proventricle, a modified foregut structure, have been proposed to have a control function during this process, though the concrete mechanisms behind it have never been elucidated. RESULTS: By using different experimental set-ups, histology and immunohistochemistry combined with subsequent cLSM analyzes, we investigate and document the regeneration and stolonization in specimens of Typosyllis antoni that were amputated at different levels throughout the antero-posterior body axis. The removal of the anterior end including the proventricle implies an incomplete anterior regeneration as well as severe deviations from the usual reproductive pattern, i.e. accelerated stolonization, masculinization and the occurrence of aberrant stolons. The detailed anatomy of aberrant stolons is described. A histological study of the proventricle revealed no signs of glandular or secretory structures. The ventricle and the caeca are composed of glandular tissue but they are not involved in the reproductive and regenerative processes. CONCLUSIONS: As in other investigated syllids, the proventricle region has a significant role during stolonization and reproduction processes in Typosyllis antoni. When the proventricle region is absent, anterior and posterior regeneration are considerably deviated from the general patterns. However, proventricle ultrastructure does not show any glandular component, thereby questioning a direct involvement of this organ itself in the control of reproduction and regeneration. Our findings offer a comprehensive starting point for further studies of regeneration and reproductive control in syllids as well as annelids in general. PMID- 27716026 TI - Arginine deiminase pathway enzymes: evolutionary history in metamonads and other eukaryotes. AB - BACKGROUND: Multiple prokaryotic lineages use the arginine deiminase (ADI) pathway for anaerobic energy production by arginine degradation. The distribution of this pathway among eukaryotes has been thought to be very limited, with only two specialized groups living in low oxygen environments (Parabasalia and Diplomonadida) known to possess the complete set of all three enzymes. We have performed an extensive survey of available sequence data in order to map the distribution of these enzymes among eukaryotes and to reconstruct their phylogenies. RESULTS: We have found genes for the complete pathway in almost all examined representatives of Metamonada, the anaerobic protist group that includes parabasalids and diplomonads. Phylogenetic analyses indicate the presence of the complete pathway in the last common ancestor of metamonads and heterologous transformation experiments suggest its cytosolic localization in the metamonad ancestor. Outside Metamonada, the complete pathway occurs rarely, nevertheless, it was found in representatives of most major eukaryotic clades. CONCLUSIONS: Phylogenetic relationships of complete pathways are consistent with the presence of the Archaea-derived ADI pathway in the last common ancestor of all eukaryotes, although other evolutionary scenarios remain possible. The presence of the incomplete set of enzymes is relatively common among eukaryotes and it may be related to the fact that these enzymes are involved in other cellular processes, such as the ornithine-urea cycle. Single protein phylogenies suggest that the evolutionary history of all three enzymes has been shaped by frequent gene losses and horizontal transfers, which may sometimes be connected with their diverse roles in cellular metabolism. PMID- 27716027 TI - Identification of gene-drug interactions that impact patient survival in TCGA. AB - BACKGROUND: With the advent of large scale biological data collection for various diseases, data analysis pipelines and workflows need to be established to build frameworks for integrative analysis. Here the authors present a pipeline for identifying disease specific gene-drug interactions using CNV (Copy Number Variation) and clinical data from the TCGA (The Cancer Genome Atlas) project. Two cancer types were selected for analysis, LGG (Brain lower grade glioma) and GBM (Glioblastoma multiforme), due to the possible progression from LGG to GBM in some cases. The copy number and clinical data were then used to preform survival analysis on a gene by gene basis on sub-populations of patients exposed to a given drug. RESULTS: Several gene-drug interactions are identified, where the copy number of a gene is associated to survival of a patient exposed to a certain drug. Both Irinotecan/HAS2 (Hyaluronan synthase 2) and Bevacizumab/PGAM1 (Phosphoglycerate mutase 1) are interactions found in this study with independent confirmation. Independent work in colon, breast cancer and leukemia (Gyorffy, Breast Cancer Res Treat 123:725-731, 2010; Mueller, Mol Cancer Ther 11:3024-3032, 2010; Hitosugi, Cancer Cell 13:585-600, 2012) showed these two interactions can lead to increased survival. CONCLUSION: While the pipeline produced several possible interactions where increased survival is linked to normal or increased copy number of a given gene for patients treated with a given drug, no instance of low copy number or full deletion was linked to increased survival. The development of this pipeline shows a promising utility to identify possible beneficial gene-drug interactions that could improve patient survival and may illustrate some of the problems inherent in this kind of analysis on these data. PMID- 27716029 TI - Simulating cryo electron tomograms of crowded cell cytoplasm for assessment of automated particle picking. AB - BACKGROUND: Cryo-electron tomography is an important tool to study structures of macromolecular complexes in close to native states. A whole cell cryo electron tomogram contains structural information of all its macromolecular complexes. However, extracting this information remains challenging, and relies on sophisticated image processing, in particular for template-free particle extraction, classification and averaging. To develop these methods it is crucial to realistically simulate tomograms of crowded cellular environments, which can then serve as ground truth models for assessing and optimizing methods for detection of complexes in cell tomograms. RESULTS: We present a framework to generate crowded mixtures of macromolecular complexes for realistically simulating cryo electron tomograms including noise and image distortions due to the missing-wedge effects. Simulated tomograms are then used for assessing the template-free Difference-of-Gaussian (DoG) particle-picking method to detect complexes of different shapes and sizes under various crowding and noise levels. We identified DoG parameter settings that maximize precision and recall for detecting particles over a wide range of sizes and shapes. We observed that medium sized DoG scaling factors showed the overall best performance. To further improve performance, we propose a combination strategy for integrating results from multiple parameter settings. With increasing macromolecular crowding levels, the precision of particle picking remained relatively high, while the recall was dramatically reduced, which limits the detection of sufficient copy numbers of complexes in a crowded environment. Over a wide range of increasing noise levels, the DoG particle picking performance remained stable, but dramatically reduced beyond a specific noise threshold. CONCLUSIONS: Automatic and reference-free particle picking is an important first step in a visual proteomics analysis of cell tomograms. However, cell cytoplasm is highly crowded, which makes particle detection challenging. It is therefore important to test particle-picking methods in a realistic crowded setting. Here, we present a framework for simulating tomograms of cellular environments at high crowding levels and assess the DoG particle picking method. We determined optimal parameter settings to maximize the performance of the DoG particle-picking method. PMID- 27716028 TI - Genetic signals of high-altitude adaptation in amphibians: a comparative transcriptome analysis. AB - BACKGROUND: High-altitude adaptation provides an excellent system for studying how organisms cope with multiple environmental stressors and interacting genetic modifications. To explore the genetic basis of high-altitude adaptation in poikilothermic animals, we acquired transcriptome sequences from a high-altitude population and a low-altitude population of the Asiatic toad (Bufo gargarizans). Transcriptome data from another high-altitude amphibian, Rana kukunoris and its low-altitude relative R. chensiensis, which are from a previous study, were also incorporated into our comparative analysis. RESULTS: More than 40,000 transcripts were obtained from each transcriptome, and 5107 one-to-one orthologs were identified among the four taxa for comparative analysis. A total of 29 (Bufo) and 33 (Rana) putative positively selected genes were identified for the two high altitude species, which were mainly concentrated in nutrient metabolism related functions. Using SNP-tagging and FST outlier analysis, we further tested 89 other nutrient metabolism related genes for signatures of natural selection, and found that two genes, CAPN2 and ITPR1, were likely under balancing selection. We did not detect any positively selected genes associated with response to hypoxia. CONCLUSIONS: Amphibians clearly employ different genetic mechanisms for high altitude adaptation compared to endotherms. Modifications of genes associated with nutrient metabolism feature prominently while genes related to hypoxia tolerance appear to be insignificant. Poikilotherms represent the majority of animal diversity, and we hope that our results will provide useful directions for future studies of amphibians as well as other poikilotherms. PMID- 27716030 TI - Handling missing rows in multi-omics data integration: multiple imputation in multiple factor analysis framework. AB - BACKGROUND: In omics data integration studies, it is common, for a variety of reasons, for some individuals to not be present in all data tables. Missing row values are challenging to deal with because most statistical methods cannot be directly applied to incomplete datasets. To overcome this issue, we propose a multiple imputation (MI) approach in a multivariate framework. In this study, we focus on multiple factor analysis (MFA) as a tool to compare and integrate multiple layers of information. MI involves filling the missing rows with plausible values, resulting in M completed datasets. MFA is then applied to each completed dataset to produce M different configurations (the matrices of coordinates of individuals). Finally, the M configurations are combined to yield a single consensus solution. RESULTS: We assessed the performance of our method, named MI-MFA, on two real omics datasets. Incomplete artificial datasets with different patterns of missingness were created from these data. The MI-MFA results were compared with two other approaches i.e., regularized iterative MFA (RI-MFA) and mean variable imputation (MVI-MFA). For each configuration resulting from these three strategies, the suitability of the solution was determined against the true MFA configuration obtained from the original data and a comprehensive graphical comparison showing how the MI-, RI- or MVI-MFA configurations diverge from the true configuration was produced. Two approaches i.e., confidence ellipses and convex hulls, to visualize and assess the uncertainty due to missing values were also described. We showed how the areas of ellipses and convex hulls increased with the number of missing individuals. A free and easy-to-use code was proposed to implement the MI-MFA method in the R statistical environment. CONCLUSIONS: We believe that MI-MFA provides a useful and attractive method for estimating the coordinates of individuals on the first MFA components despite missing rows. MI-MFA configurations were close to the true configuration even when many individuals were missing in several data tables. This method takes into account the uncertainty of MI-MFA configurations induced by the missing rows, thereby allowing the reliability of the results to be evaluated. PMID- 27716031 TI - Boolean regulatory network reconstruction using literature based knowledge with a genetic algorithm optimization method. AB - BACKGROUND: Prior knowledge networks (PKNs) provide a framework for the development of computational biological models, including Boolean models of regulatory networks which are the focus of this work. PKNs are created by a painstaking process of literature curation, and generally describe all relevant regulatory interactions identified using a variety of experimental conditions and systems, such as specific cell types or tissues. Certain of these regulatory interactions may not occur in all biological contexts of interest, and their presence may dramatically change the dynamical behaviour of the resulting computational model, hindering the elucidation of the underlying mechanisms and reducing the usefulness of model predictions. Methods are therefore required to generate optimized contextual network models from generic PKNs. RESULTS: We developed a new approach to generate and optimize Boolean networks, based on a given PKN. Using a genetic algorithm, a model network is built as a sub-network of the PKN and trained against experimental data to reproduce the experimentally observed behaviour in terms of attractors and the transitions that occur between them under specific perturbations. The resulting model network is therefore contextualized to the experimental conditions and constitutes a dynamical Boolean model closer to the observed biological process used to train the model than the original PKN. Such a model can then be interrogated to simulate response under perturbation, to detect stable states and their properties, to get insights into the underlying mechanisms and to generate new testable hypotheses. CONCLUSIONS: Generic PKNs attempt to synthesize knowledge of all interactions occurring in a biological process of interest, irrespective of the specific biological context. This limits their usefulness as a basis for the development of context-specific, predictive dynamical Boolean models. The optimization method presented in this article produces specific, contextualized models from generic PKNs. These contextualized models have improved utility for hypothesis generation and experimental design. The general applicability of this methodological approach makes it suitable for a variety of biological systems and of general interest for biological and medical research. Our method was implemented in the software optimusqual, available online at http://www.vital-it.ch/software/optimusqual/ .

AB - BACKGROUND: To explore the relationship between spatial genome organization and gene expression in the interphase nucleus, we used a genomic imprinting model, which offers parental-specific gene expression. Using 3D FISH in porcine fetal liver cells, we compared the nuclear organization of the two parental alleles (expressed or not) of insulin-like growth factor 2 (IGF2), a paternally imprinted gene located on chromosome 2. We investigated whether its nuclear positioning favors specific locus associations. We also tested whether IGF2 is implicated in long-range chromatin trans-associations as previously shown in the mouse model species for its reciprocal imprinted gene H19. RESULTS: We focused on the 3D position of IGF2 alleles, with respect to their individual chromosome 2 territories. The paternally expressed allele was tagged with nascent RNA. There were no significant differences in the position of the two alleles (p = 0.06). To determine long-range chromatin trans-interactions, we chose 12 genes, some of which are known to be imprinted in mammalian model species and belong to a network of imprinted genes (i.e. SLC38A4, DLK1, MEG3, and ZAC1). We screened them and ABCG2, OSBP2, OSBPL1, RPL32, NF1, ZAR1, SEP15, GPC3 for associations with IGF2 in liver cells. All imprinted genes tested showed an association with IGF2. The DLK1/MEG3 locus showed the highest rate of colocalization. This gene association was confirmed by 3D FISH (in 20 % of the nuclei analyzed), revealing also the close proximity of chromosomes 2 and 7 (in 60 % of nuclei). Furthermore, our observations showed that the expressed paternal IGF2 allele is involved in this association. This IGF2-(DLK1/MEG3) association also occurred in a high percentage of fetal muscle cells (36 % of nuclei). Finally, we showed that nascent IGF2, DLK1 and MEG3 RNAs can associate in pairs or in a three-way combination. CONCLUSION: Our results show that trans-associations occur between three imprinted genes IGF2, DLK1 and MEG3 both in fetal liver and muscle cells. All three expressed alleles associated in muscle cells. Our findings suggest that the 3D nuclear organization is linked to the transcriptional state of these genes. PMID- 27716034 TI - VennDiagramWeb: a web application for the generation of highly customizable Venn and Euler diagrams. AB - BACKGROUND: Visualization of data generated by high-throughput, high dimensionality experiments is rapidly becoming a rate-limiting step in computational biology. There is an ongoing need to quickly develop high-quality visualizations that can be easily customized or incorporated into automated pipelines. This often requires an interface for manual plot modification, rapid cycles of tweaking visualization parameters, and the generation of graphics code. To facilitate this process for the generation of highly-customizable, high resolution Venn and Euler diagrams, we introduce VennDiagramWeb: a web application for the widely used VennDiagram R package. VennDiagramWeb is hosted at http://venndiagram.res.oicr.on.ca/ . RESULTS: VennDiagramWeb allows real-time modification of Venn and Euler diagrams, with parameter setting through a web interface and immediate visualization of results. It allows customization of essentially all aspects of figures, but also supports integration into computational pipelines via download of R code. Users can upload data and download figures in a range of formats, and there is exhaustive support documentation. CONCLUSIONS: VennDiagramWeb allows the easy creation of Venn and Euler diagrams for computational biologists, and indeed many other fields. Its ability to support real-time graphics changes that are linked to downloadable code that can be integrated into automated pipelines will greatly facilitate the improved visualization of complex datasets. For application support please contact Paul.Boutros@oicr.on.ca. PMID- 27716033 TI - Adrenal cortex expression quantitative trait loci in a German Holstein * Charolais cross. AB - BACKGROUND: The importance of the adrenal gland in regard to lactation and reproduction in cattle has been recognized early. Caused by interest in animal welfare and the impact of stress on economically important traits in farm animals the adrenal gland and its function within the stress response is of increasing interest. However, the molecular mechanisms and pathways involved in stress related effects on economically important traits in farm animals are not fully understood. Gene expression is an important mechanism underlying complex traits, and genetic variants affecting the transcript abundance are thought to influence the manifestation of an expressed phenotype. We therefore investigated the genetic background of adrenocortical gene expression by applying an adaptive linear rank test to identify genome-wide expression quantitative trait loci (eQTL) for adrenal cortex transcripts in cattle. RESULTS: A total of 10,986 adrenal cortex transcripts and 37,204 single nucleotide polymorphisms (SNPs) were analysed in 145 F2 cows of a Charolais * German Holstein cross. We identified 505 SNPs that were associated with the abundance of 129 transcripts, comprising 482 cis effects and 17 trans effects. These SNPs were located on all chromosomes but X, 16, 24 and 28. Associated genes are mainly involved in molecular and cellular functions comprising free radical scavenging, cellular compromise, cell morphology and lipid metabolism, including genes such as CYP27A1 and LHCGR that have been shown to affect economically important traits in cattle. CONCLUSIONS: In this study we showed that adrenocortical eQTL affect the expression of genes known to contribute to the phenotypic manifestation in cattle. Furthermore, some of the identified genes and related molecular pathways were previously shown to contribute to the phenotypic variation of behaviour, temperament and growth at the onset of puberty in the same population investigated here. We conclude that eQTL analysis appears to be a useful approach providing insight into the molecular and genetic background of complex traits in cattle and will help to understand molecular networks involved. PMID- 27716036 TI - Identification of large disjoint motifs in biological networks. AB - BACKGROUND: Biological networks provide great potential to understand how cells function. Network motifs, frequent topological patterns, are key structures through which biological networks operate. Finding motifs in biological networks remains to be computationally challenging task as the size of the motif and the underlying network grow. Often, different copies of a given motif topology in a network share nodes or edges. Counting such overlapping copies introduces significant problems in motif identification. RESULTS: In this paper, we develop a scalable algorithm for finding network motifs. Unlike most of the existing studies, our algorithm counts independent copies of each motif topology. We introduce a set of small patterns and prove that we can construct any larger pattern by joining those patterns iteratively. By iteratively joining already identified motifs with those patterns, our algorithm avoids (i) constructing topologies which do not exist in the target network (ii) repeatedly counting the frequency of the motifs generated in subsequent iterations. Our experiments on real and synthetic networks demonstrate that our method is significantly faster and more accurate than the existing methods including SUBDUE and FSG. CONCLUSIONS: We conclude that our method for finding network motifs is scalable and computationally feasible for large motif sizes and a broad range of networks with different sizes and densities. We proved that any motif with four or more edges can be constructed as a join of the small patterns. PMID- 27716035 TI - Molecular evolution of Odorant-binding proteins gene family in two closely related Anastrepha fruit flies. AB - BACKGROUND: Odorant-binding proteins (OBPs) are of great importance for survival and reproduction since they participate in initial steps of the olfactory signal transduction cascade, solubilizing and transporting chemical signals to the olfactory receptors. A comparative analysis of OBPs between closely related species may help explain how these genes evolve and are maintained under natural selection and how differences in these proteins can affect olfactory responses. We studied OBP genes in the closely related species Anastrepha fraterculus and A. obliqua, which have different host preferences, using data from RNA-seq cDNA libraries of head and reproductive tissues from male and female adults, aiming to understand the speciation process occurred between them. RESULTS: We identified 23 different OBP sequences from Anastrepha fraterculus and 24 from A. obliqua, which correspond to 20 Drosophila melanogaster OBP genes. Phylogenetic analysis separated Anastrepha OBPs sequences in four branches that represent four subfamilies: classic, minus-C, plus-C and dimer. Both species showed five plus-C members, which is the biggest number found in tephritids until now. We found evidence of positive selection in four genes and at least one duplication event that preceded the speciation of these two species. Inferences on tertiary structures of putative proteins from these genes revealed that at least one positively selected change involves the binding cavity (the odorant binding region) in the plus-C OBP50a. CONCLUSIONS: A. fraterculus and A. obliqua have a bigger OBP repertoire than the other tephritids studied, though the total number of Anastrepha OBPs may be larger, since we studied only a limited number of tissues. The contrast of these closely related species reveals that there are several amino acid changes between the homologous genes, which might be related to their host preferences. The plus-C OBP that has one amino acid under positive selection located in the binding cavity may be under a selection pressure to recognize and bind a new odorant. The other positively selected sites found may be involved in important structural and functional changes, especially ones in which site-specific changes would radically change amino acid properties. PMID- 27716037 TI - Impact of post-alignment processing in variant discovery from whole exome data. AB - BACKGROUND: GATK Best Practices workflows are widely used in large-scale sequencing projects and recommend post-alignment processing before variant calling. Two key post-processing steps include the computationally intensive local realignment around known INDELs and base quality score recalibration (BQSR). Both have been shown to reduce erroneous calls; however, the findings are mainly supported by the analytical pipeline that incorporates BWA and GATK UnifiedGenotyper. It is not known whether there is any benefit of post-processing and to what extent the benefit might be for pipelines implementing other methods, especially given that both mappers and callers are typically updated. Moreover, because sequencing platforms are upgraded regularly and the new platforms provide better estimations of read quality scores, the need for post-processing is also unknown. Finally, some regions in the human genome show high sequence divergence from the reference genome; it is unclear whether there is benefit from post processing in these regions. RESULTS: We used both simulated and NA12878 exome data to comprehensively assess the impact of post-processing for five or six popular mappers together with five callers. Focusing on chromosome 6p21.3, which is a region of high sequence divergence harboring the human leukocyte antigen (HLA) system, we found that local realignment had little or no impact on SNP calling, but increased sensitivity was observed in INDEL calling for the Stampy + GATK UnifiedGenotyper pipeline. No or only a modest effect of local realignment was detected on the three haplotype-based callers and no evidence of effect on Novoalign. BQSR had virtually negligible effect on INDEL calling and generally reduced sensitivity for SNP calling that depended on caller, coverage and level of divergence. Specifically, for SAMtools and FreeBayes calling in the regions with low divergence, BQSR reduced the SNP calling sensitivity but improved the precision when the coverage is insufficient. However, in regions of high divergence (e.g., the HLA region), BQSR reduced the sensitivity of both callers with little gain in precision rate. For the other three callers, BQSR reduced the sensitivity without increasing the precision rate regardless of coverage and divergence level. CONCLUSIONS: We demonstrated that the gain from post-processing is not universal; rather, it depends on mapper and caller combination, and the benefit is influenced further by sequencing depth and divergence level. Our analysis highlights the importance of considering these key factors in deciding to apply the computationally intensive post-processing to Illumina exome data. PMID- 27716038 TI - ChiLin: a comprehensive ChIP-seq and DNase-seq quality control and analysis pipeline. AB - BACKGROUND: Transcription factor binding, histone modification, and chromatin accessibility studies are important approaches to understanding the biology of gene regulation. ChIP-seq and DNase-seq have become the standard techniques for studying protein-DNA interactions and chromatin accessibility respectively, and comprehensive quality control (QC) and analysis tools are critical to extracting the most value from these assay types. Although many analysis and QC tools have been reported, few combine ChIP-seq and DNase-seq data analysis and quality control in a unified framework with a comprehensive and unbiased reference of data quality metrics. RESULTS: ChiLin is a computational pipeline that automates the quality control and data analyses of ChIP-seq and DNase-seq data. It is developed using a flexible and modular software framework that can be easily extended and modified. ChiLin is ideal for batch processing of many datasets and is well suited for large collaborative projects involving ChIP-seq and DNase-seq from different designs. ChiLin generates comprehensive quality control reports that include comparisons with historical data derived from over 23,677 public ChIP-seq and DNase-seq samples (11,265 datasets) from eight literature-based classified categories. To the best of our knowledge, this atlas represents the most comprehensive ChIP-seq and DNase-seq related quality metric resource currently available. These historical metrics provide useful heuristic quality references for experiment across all commonly used assay types. Using representative datasets, we demonstrate the versatility of the pipeline by applying it to different assay types of ChIP-seq data. The pipeline software is available open source at https://github.com/cfce/chilin . CONCLUSION: ChiLin is a scalable and powerful tool to process large batches of ChIP-seq and DNase-seq datasets. The analysis output and quality metrics have been structured into user friendly directories and reports. We have successfully compiled 23,677 profiles into a comprehensive quality atlas with fine classification for users. PMID- 27716039 TI - Parametric bootstrapping for biological sequence motifs. AB - BACKGROUND: Biological sequence motifs drive the specific interactions of proteins and nucleic acids. Accordingly, the effective computational discovery and analysis of such motifs is a central theme in bioinformatics. Many practical questions about the properties of motifs can be recast as random sampling problems. In this light, the task is to determine for a given motif whether a certain feature of interest is statistically unusual among relevantly similar alternatives. Despite the generality of this framework, its use has been frustrated by the difficulties of defining an appropriate reference class of motifs for comparison and of sampling from it effectively. RESULTS: We define two distributions over the space of all motifs of given dimension. The first is the maximum entropy distribution subject to mean information content, and the second is the truncated uniform distribution over all motifs having information content within a given interval. We derive exact sampling algorithms for each. As a proof of concept, we employ these sampling methods to analyze a broad collection of prokaryotic and eukaryotic transcription factor binding site motifs. In addition to positional information content, we consider the informational Gini coefficient of the motif, a measure of the degree to which information is evenly distributed throughout a motif's positions. We find that both prokaryotic and eukaryotic motifs tend to exhibit higher informational Gini coefficients (IGC) than would be expected by chance under either reference distribution. As a second application, we apply maximum entropy sampling to the motif p-value problem and use it to give elementary derivations of two new estimators. CONCLUSIONS: Despite the historical centrality of biological sequence motif analysis, this study constitutes to our knowledge the first use of principled null hypotheses for sequence motifs given information content. Through their use, we are able to characterize for the first time differerences in global motif statistics between biological motifs and their null distributions. In particular, we observe that biological sequence motifs show an unusual distribution of IGC, presumably due to biochemical constraints on the mechanisms of direct read-out. PMID- 27716040 TI - A decision analysis model for KEGG pathway analysis. AB - BACKGROUND: The knowledge base-driven pathway analysis is becoming the first choice for many investigators, in that it not only can reduce the complexity of functional analysis by grouping thousands of genes into just several hundred pathways, but also can increase the explanatory power for the experiment by identifying active pathways in different conditions. However, current approaches are designed to analyze a biological system assuming that each pathway is independent of the other pathways. RESULTS: A decision analysis model is developed in this article that accounts for dependence among pathways in time course experiments and multiple treatments experiments. This model introduces a decision coefficient-a designed index, to identify the most relevant pathways in a given experiment by taking into account not only the direct determination factor of each Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway itself, but also the indirect determination factors from its related pathways. Meanwhile, the direct and indirect determination factors of each pathway are employed to demonstrate the regulation mechanisms among KEGG pathways, and the sign of decision coefficient can be used to preliminarily estimate the impact direction of each KEGG pathway. The simulation study of decision analysis demonstrated the application of decision analysis model for KEGG pathway analysis. CONCLUSIONS: A microarray dataset from bovine mammary tissue over entire lactation cycle was used to further illustrate our strategy. The results showed that the decision analysis model can provide the promising and more biologically meaningful results. Therefore, the decision analysis model is an initial attempt of optimizing pathway analysis methodology. PMID- 27716042 TI - Erratum to: Transcriptome responses to temperature, water availability and photoperiod are conserved among mature trees of two divergent Douglas-fir provenances from a coastal and an interior habitat. PMID- 27716041 TI - Glycoside hydrolases family 20 (GH20) represent putative virulence factors that are shared by animal pathogenic oomycetes, but are absent in phytopathogens. AB - BACKGROUND: Although interest in animal pathogenic oomycetes is increasing, the molecular basis mediating oomycete-animal relationships remains virtually unknown. Crinkler (CRN) genes, which have been traditionally associated with the cytotoxic activity displayed by plant pathogenic oomycetes, were recently detected in transcriptome sequences from the entomopathogenic oomycete Lagenidium giganteum, suggesting that these genes may represent virulence factors conserved in both animal and plant pathogenic oomycetes. In order to further characterize the L. giganteum pathogenome, an on-going genomic survey was mined to reveal novel putative virulence factors, including canonical oomycete effectors Crinkler 13 (CRN13) orthologs. These novel sequences provided a basis to initiate gene expression analyses and determine if the proposed L. giganteum virulence factors are differentially expressed in the presence of mosquito larvae (Aedes aegypti). RESULTS: Sequence analyses revealed that L. giganteum express CRN13 transcripts. The predicted proteins, like other L. giganteum CRNs, contained a conserved LYLA motif at the N terminal, but did not display signal peptides. In contrast, other potential virulence factors, such as Glycoside Hydrolases family 20 (hexosaminidase) and 37 (trehalase) proteins (GH20 and GH37), contained identifiable signal peptides. Genome mining demonstrated that GH20 genes are absent from phytopathogenic oomycete genomes, and that the L. giganteum GH20 sequence is the only reported peronosporalean GH20 gene. All other oomycete GH20 homologs were retrieved from animal pathogenic, saprolegnialean genomes. Furthermore, phylogenetic analyses demonstrated that saprolegnialean and peronosporalean GH20 protein sequences clustered in unrelated clades. The saprolegnialean GH20 sequences appeared as a strongly supported, monophyletic group nested within an arthropod-specific clade, suggesting that this gene was acquired via a lateral gene transfer event from an insect or crustacean genome. In contrast, the L. giganteum GH20 protein sequence appeared as a sister taxon to a plant-specific clade that included exochitinases with demonstrated insecticidal activities. Finally, gene expression analyses demonstrated that the L. giganteum GH20 gene expression level is significantly modulated in the presence of mosquito larvae. In agreement with the protein secretion predictions, CRN transcripts did not show any differential expression. CONCLUSIONS: These results identified GH20 enzymes, and not CRNs, as potential pathogenicity factors shared by all animal pathogenic oomycetes. PMID- 27716043 TI - The succession pattern of soil microbial communities and its relationship with tobacco bacterial wilt. AB - BACKGROUND: The interaction mechanism between crop and soil microbial communities is a key issue in both agriculture and soil ecology. However, how soil microbial communities respond to crop planting and ultimately affect crop health still remain unclear. In this research, we explored how soil microbial communities shifted during tobacco cultivation under different rotation systems (control, maize rotation, lily rotation and turnip rotation). RESULTS: Our analyses showed that soil microbial communities had a general response pattern to tobacco planting, as the abundances of Proteobacteria and Planctomycetes increased while Acidobacteria and Verrucomicrobia decreased during tobacco cultivation, no matter which rotation system was adopted. Notably, tobacco decreased the diversity and co-occurrence of soil microorganisms, but maize rotation might suppress tobacco bacterial wilt by alleviating the decrease in biodiversity and co-occurrence. Molecular ecological network analysis indicated that there was stronger competition between potential disease suppressive (e.g., Acidobacteria) and inducible bacteria (e.g., Chloroflexi) in maize rotation systems. Both soil properties (e.g., pH, Ca content) and microbial communities of tobacco mature period depended on their counterparts of fallow period, and all these factors shaped tobacco disease comprehensively. CONCLUSIONS: Both soil microbial communities of fallow stage and tobacco selection shaped the communities of tobacco mature stage. And effective rotation crop (maize) could decrease the incidence of tobacco bacterial wilt by alleviating the decrease in diversity and co-occurrences of microbial populations. This study would deepen our understanding about succession mechanism of soil microbial communities during crop cultivation and their relationship with crop health. PMID- 27716044 TI - Identification and expression analysis of OsLPR family revealed the potential roles of OsLPR3 and 5 in maintaining phosphate homeostasis in rice. AB - BACKGROUND: Phosphorus (P), an essential macronutrient, is often limiting in soils and affects plant growth and development. In Arabidopsis thaliana, Low Phosphate Root1 (LPR1) and its close paralog LPR2 encode multicopper oxidases (MCOs). They regulate meristem responses of root system to phosphate (Pi) deficiency. However, the roles of LPR gene family in rice (Oryza sativa) in maintaining Pi homeostasis have not been elucidated as yet. RESULTS: Here, the identification and expression analysis for the homologs of LPR1/2 in rice were carried out. Five homologs, hereafter referred to as OsLPR1-5, were identified in rice, which are distributed on chromosome1 over a range of 65 kb. Phylogenetic analysis grouped OsLPR1/3/4/5 and OsLPR2 into two distinct sub-clades with OsLPR3 and 5 showing close proximity. Quantitative real-time RT-PCR (qRT-PCR) analysis revealed higher expression levels of OsLPR3-5 and OsLPR2 in root and shoot, respectively. Deficiencies of different nutrients ie, P, nitrogen (N), potassium (K), magnesium (Mg) and iron (Fe) exerted differential and partially overlapping effects on the relative expression levels of the members of OsLPR family. Pi deficiency (-P) triggered significant increases in the relative expression levels of OsLPR3 and 5. Strong induction in the relative expression levels of OsLPR3 and 5 in osphr2 suggested their negative transcriptional regulation by OsPHR2. Further, the expression levels of OsLPR3 and 5 were either attenuated in ossiz1 and ospho2 or augmented in rice overexpressing OsSPX1. CONCLUSIONS: The results from this study provided insights into the evolutionary expansion and a likely functional divergence of OsLPR family with potential roles of OsLPR3 and 5 in the maintenance of Pi homeostasis in rice. PMID- 27716045 TI - Iron homeostasis in Arabidopsis thaliana: transcriptomic analyses reveal novel FIT-regulated genes, iron deficiency marker genes and functional gene networks. AB - BACKGROUND: FIT (FER-LIKE IRON DEFICIENCY-INDUCED TRANSCRIPTION FACTOR) is the central regulator of iron uptake in Arabidopsis thaliana roots. We performed transcriptome analyses of six day-old seedlings and roots of six week-old plants using wild type, a fit knock-out mutant and a FIT over-expression line grown under iron-sufficient or iron-deficient conditions. We compared genes regulated in a FIT-dependent manner depending on the developmental stage of the plants. We assembled a high likelihood dataset which we used to perform co-expression and functional analysis of the most stably iron deficiency-induced genes. RESULTS: 448 genes were found FIT-regulated. Out of these, 34 genes were robustly FIT regulated in root and seedling samples and included 13 novel FIT-dependent genes. Three hundred thirty-one genes showed differential regulation in response to the presence and absence of FIT only in the root samples, while this was the case for 83 genes in the seedling samples. We assembled a virtual dataset of iron regulated genes based on a total of 14 transcriptomic analyses of iron-deficient and iron-sufficient wild-type plants to pinpoint the best marker genes for iron deficiency and analyzed this dataset in depth. Co-expression analysis of this dataset revealed 13 distinct regulons part of which predominantly contained functionally related genes. CONCLUSIONS: We could enlarge the list of FIT dependent genes and discriminate between genes that are robustly FIT-regulated in roots and seedlings or only in one of those. FIT-regulated genes were mostly induced, few of them were repressed by FIT. With the analysis of a virtual dataset we could filter out and pinpoint new candidates among the most reliable marker genes for iron deficiency. Moreover, co-expression and functional analysis of this virtual dataset revealed iron deficiency-induced and functionally distinct regulons. PMID- 27716046 TI - Immune analysis of expression of IL-17 relative ligands and their receptors in bladder cancer: comparison with polyp and cystitis. AB - BACKGROUND: Bladder cancer, cystitis and bladder polyp are the most common urinary system diseases all over the world. Our former research results show that IL-17A and IL-17 F contribute to the pathogenesis of benign prostatic hyperplasia (BPH) and prostate cancer (Pca) while IL-17E interacting with IL-17RB might have an anti-tumor effect. RESULTS: Using imunohistochemistry, we systemically compared immunoreactivity of ligands (IL-17A, E and F) and receptors (IL-17RA, IL 17RB and IL-17RC) of IL-17 family, infiltration of inflammatory cells and changes of structural cells (fibroblast cells, smooth muscle and vascular endothelial cells) in sections of bladder tissues from subjects with bladder cancer, cystitis and bladder polyp. Compared with subjects with cystitis, immunoreactivity for IL 17A, IL-17 F and IL-17RC was significantly elevated in the group of bladder cancer (p < 0.01), while immunoreactivity of IL-17E, IL-17RA and IL-17RB, and the infiltrating neutrophils were decreased (p < 0.05). The numbers of infiltrating lymphocytes and phagocytes and CD31+ blood vessels and immunoreactivity of CD90+ fibroblasts were also elevated in patients with bladder cancer compared with those of cystitis. The patterns of IL-17 ligands and receptors, and inflammatory cells and structural cells varied in cystitis, bladder polyp and bladder cancer. In bladder cancer, immunoreactivity of IL-17E and IL-17 F was positively correlated with smooth muscles and lymphocytes, respectively. In addition, immunoreactivity of IL-17A and IL-17E was positively correlated with their receptors IL-17RA and IL-17RB respectively. CONCLUSIONS: The data suggest that changed patterns of expression of the IL-17 cytokine family ligands and receptors might be associated with infiltration of inflammatory cells and structural cells (CD90+ fibroblasts and CD31+ blood vessels), which might also contribute to occurrence and development in bladder cancer. PMID- 27716047 TI - Intranasal immunization with recombinant Toxoplasma gondii actin depolymerizing factor confers protective efficacy against toxoplasmosis in mice. AB - BACKGROUND: Toxoplasma gondii is an opportunistic protozoan closely associated with AIDS and vertical transmission. T. gondii actin depolymerizing factor (TgADF) plays an important role in actin cytoskeleton remodeling, and it is required to invade host cells. TgADF was a promising vaccine candidate. To observe the immunological changes and protective efficacy of recombinant TgADF protein (rTgADF) against T. gondii infection, we optimized the intranasal immunization dose of rTgADF and analyzed the survival rate and tachyzoite loads in mouse tissues after oral challenge with T. gondii tachyzoites. RESULTS: rTgADF was prepared, purified, and combined with mouse anti-His antibody and rabbit anti T. gondii serum. After intranasal immunization with 10 MUg, 20 MUg, 30 MUg, or 40 MUg of rTgADF, the 30-MUg group elicited high levels of secretory IgA (sIgA) in nasal, intestinal, and vesical washes, raised IgG titres in the sera, strong proliferation of splenocytes, and increased secretion of IL-2 and IFN-gamma when compared with the control group. When the mice were orally challenged with T. gondii, an increase in the survival rate (36.36 %) and a decrease in the tachyzoite loads in the liver (67.77 %) and brain (51.01 %) were observed. CONCLUSIONS: Our findings demonstrate that intranasal immunization with rTgADF can simultaneously trigger mucosal and systemic immune responses and protect the mice against T. gondii infection. PMID- 27716048 TI - Glycan-binding F-box protein from Arabidopsis thaliana protects plants from Pseudomonas syringae infection. AB - BACKGROUND: A small group of F-box proteins consisting of a conserved F-box domain linked to a domain homologous to the glycan-binding protein has been identified within the genome of Arabidopsis thaliana. Previously, the so-called F box-Nictaba protein, encoded by the gene At2g02360, was shown to be a functional lectin which binds N-acetyllactosamine structures. Here, we present a detailed qRT-PCR expression analysis of F-box-Nictaba in Arabidopsis plants upon different stresses and hormone treatments. RESULTS: Expression of the F-box-Nictaba gene was enhanced after plant treatment with salicylic acid and after plant infection with the virulent Pseudomonas syringae pv. tomato strain DC3000 (Pst DC3000). beta-glucuronidase histochemical staining of transgenic Arabidopsis plants displayed preferential activity of the At2g02360 promoter in trichomes present on young rosette leaves. qRT-PCR analyses confirmed high expression of F-box-Nictaba in leaf trichomes. A. thaliana plants overexpressing the gene showed less disease symptoms after Pst DC3000 infection with reduced bacterial colonization compared to infected wild type and F-box-Nictaba knock-out plants. CONCLUSIONS: Our data show that the Arabidopsis F-box-Nictaba gene is a stress-inducible gene responsive to SA, bacterial infection and heat stress, and is involved in salicylic acid related plant defense responses. This knowledge enriched our understanding of the physiological importance of F-box-Nictaba, and can be used to create plants with better performance in changing environmental conditions.

AB - BACKGROUND: Clostridium difficile is a spore-forming obligate anaerobe that can remain viable for extended periods, even in the presence of antibiotics, which contributes to the persistence of this bacterium as a human pathogen during host to-host transmission and in hospital environments. We examined the structure and function of a gene product with the locus tag CDR20291_0991 (cdPadR1) as part of our broader goal aimed at elucidating transcription regulatory mechanisms involved in virulence and antibiotic resistance of the recently emergent hypervirulent C. difficile strain R20291. cdPadR1 is genomically positioned near genes that are involved in stress response and virulence. In addition, it was previously reported that cdPadR1 and a homologue from the historical C. difficile strain 630 (CD630_1154) were differentially expressed when exposed to stressors, including antibiotics. RESULTS: The crystal structure of cdPadR1 was determined to 1.9 A resolution, which revealed that it belongs to the PadR-s2 subfamily of PadR transcriptional regulators. cdPadR1 binds its own promoter and other promoter regions from within the C. difficile R20291 genome. DNA binding experiments demonstrated that cdPadR1 binds a region comprised of inverted repeats and an AT-rich core with the predicted specific binding motif, GTACTAT(N2)ATTATA(N)AGTA, within its own promoter that is also present in 200 other regions in the C. difficile R20291 genome. Mutation of the highly conserved W in alpha4 of the effector binding/oligomerization domain, which is predicted to be involved in multi-drug recognition and dimerization in other PadR-s2 proteins, resulted in alterations of cdPadR1 binding to the predicted binding motif, potentially due to loss of higher order oligomerization. CONCLUSIONS: Our results indicate that cdPadR1 binds a region within its own promoter consisting of the binding motif GTACTAT(N2)ATTATA(N)AGTA and seems to associate non-specifically with longer DNA fragments in vitro, which may facilitate promoter and motif searching. This suggests that cdPadR1 acts as a transcriptional auto-regulator, binding specific sites within its own promoter, and is part of a broad gene regulatory network involved, in part, with environmental stress response, antibiotic resistance and virulence. PMID- 27716051 TI - Development of EMS-induced mutation population for amylose and resistant starch variation in bread wheat (Triticum aestivum) and identification of candidate genes responsible for amylose variation. AB - BACKGROUND: Starch is a major part of cereal grain. It comprises two glucose polymer fractions, amylose (AM) and amylopectin (AP), that make up about 25 and 75 % of total starch, respectively. The ratio of the two affects processing quality and digestibility of starch-based food products. Digestibility determines nutritional quality, as high amylose starch is considered a resistant or healthy starch (RS type 2) and is highly preferred for preventive measures against obesity and related health conditions. The topic of nutrition security is currently receiving much attention and consumer demand for food products with improved nutritional qualities has increased. In bread wheat (Triticum aestivum L.), variation in amylose content is narrow, hence its limited improvement. Therefore, it is necessary to produce wheat lines or populations showing wide variation in amylose/resistant starch content. In this study, a set of EMS induced M4 mutant lines showing dynamic variation in amylose/resistant starch content were produced. Furthermore, two diverse mutant lines for amylose content were used to study quantitative expression patterns of 20 starch metabolic pathway genes and to identify candidate genes for amylose biosynthesis. RESULTS: A population comprising 101 EMS-induced mutation lines (M4 generation) was produced in a bread wheat (Triticum aestivum) variety. Two methods of amylose measurement in grain starch showed variation in amylose content ranging from ~3 to 76 % in the population. The method of in vitro digestion showed variation in resistant starch content from 1 to 41 %. One-way ANOVA analysis showed significant variation (p < 0.05) in amylose and resistant starch content within the population. A multiple comparison test (Dunnett's test) showed that significant variation in amylose and resistant starch content, with respect to the parent, was observed in about 89 and 38 % of the mutant lines, respectively. Expression pattern analysis of 20 starch metabolic pathway genes in two diverse mutant lines (low and high amylose mutants) showed higher expression of key genes of amylose biosynthesis (GBSSI and their isoforms) in the high amylose mutant line, in comparison to the parent. Higher expression of amylopectin biosynthesis (SBE) was observed in the low amylose mutant lines. An additional six candidate genes showed over-expression (BMY, SPA) and reduced-expression (SSIII, SBEI, SBEIII, ISA3) in the high amylose mutant line, indicating that other starch metabolic genes may also contribute to amylose biosynthesis. CONCLUSION: In this study a set of 101 EMS-induced mutant lines (M4 generation) showing variation in amylose and resistant starch content in seed were produced. This population serves as useful germplasm or pre-breeding material for genome-wide study and improvement of starch-based processing and nutrition quality in wheat. It is also useful for the study of the genetic and molecular basis of amylose/resistant starch variation in wheat. Furthermore, gene expression analysis of 20 starch metabolic genes in the two diverse mutant lines (low and high amylose mutants) indicates that in addition to key genes, several other genes (such as phosphorylases, isoamylases, and pullulanases) may also be involved in contributing to amylose/amylopectin biosynthesis. PMID- 27716052 TI - De novo assembly and transcriptome characterization of spruce dwarf mistletoe Arceuthobium sichuanense uncovers gene expression profiling associated with plant development. AB - BACKGROUND: The parasitic flowering plant dwarf mistletoe (Arceuthobium spp., Viscaceae) is one of the most destructive forest pests, posing a major threat to numerous conifer species worldwide. Arceuthobium sichuanense (spruce dwarf mistletoe, SDM) infects Qinghai spruce (Picea crassifolia) and causes severe damage to spruce forests in Northwest China. SDM is a Chinese native parasitic plant and acquires carbohydrates and mineral nutrition from its hosts. However, underlying molecular basis of the physiological development is largely unknown. Investigations of these physiological traits have been hampered by the lack of genomic resources for this species. RESULTS: In this study, to investigate the transcriptomic processes underlying physiological traits and development in SDM, we used RNA from four major tissues (i.e., shoots, flowers, fruits, and seeds) for de novo assembly and to annotate the transcriptome of this species. We uncovered the annotated transcriptome and performed whole genome expression profiling to uncover transcriptional dynamics during physiological development, and we identified key gene categories involved in the process of sexual development. The assembled SDM transcriptome reported in this work contains 331,347 assembled transcripts; 226,687 unigenes were functionally annotated by Gene Ontology analysis. RNA-Seq analysis using this reference transcriptome identified 22,641 differentially expressed genes from shoots, flowers, fruits, and seeds. These genes are enriched in processes including organic substance metabolism, cellular metabolism, biosynthesis, and cellular component. In addition, genes related to transport, transcription, hormone biosynthesis and signaling, carbohydrate metabolism, and photosynthesis were differentially expressed between tissues. CONCLUSION: This work reveals tissue-specific gene expression patterns and pathways of SDM and implied to a difference between photosynthetic and non-photosynthetic tissues in plants. The data can potentially be used for future investigations on endophytic parasitism and SDM-spruce interaction, and it dramatically increases the available genomic resources for Arceuthobium and dwarf mistletoe communities. This preliminary study of the Arceuthobium transcriptome provides excellent opportunities for characterizing plant parasitic genes with unknown functions. PMID- 27716053 TI - Metatranscriptome analysis reveals bacterial symbiont contributions to lower termite physiology and potential immune functions. AB - BACKGROUND: Symbioses throughout the animal kingdom are known to extend physiological and ecological capabilities to hosts. Insect-microbe associations are extremely common and are often related to novel niche exploitation, fitness advantages, and even speciation events. These phenomena include expansions in host diet, detoxification of insecticides and toxins, and increased defense against pathogens. However, dissecting the contributions of individual groups of symbionts at the molecular level is often underexplored due to methodological and analytical limitations. Termites are one of the best studied systems for physiological collaborations between host and symbiota; however, most work in lower termites (those with bacterial and protist symbionts) focuses on the eukaryotic members of this symbiotic consortium. Here we present a metatranscriptomic analysis which provides novel insights into bacterial contributions to the holobiont of the eastern subterranean termite, Reticulitermes flavipes, in the presence and absence of a fungal pathogen. RESULTS: Using a customized ribodepletion strategy, a metatranscriptome assembly was obtained representing the host termite as well as bacterial and protist symbiota. Sequence data provide new insights into biosynthesis, catabolism, and transport of major organic molecules and ions by the gut consortium, and corroborate previous findings suggesting that bacteria play direct roles in nitrogen fixation, amino acid biosynthesis, and lignocellulose digestion. With regard to fungal pathogen challenge, a total of 563 differentially expressed candidate host and symbiont contigs were identified (162 up- and 401 downregulated; alpha/FDR = 0.05) including an upregulated bacterial amidohydrolase. CONCLUSIONS: This study presents the most complete bacterial metatranscriptome from a lower termite and provides a framework on which to build a more complete model of termite-symbiont interactions including, but not limited to, digestion and pathogen defense. PMID- 27716054 TI - Ethylene responsive transcription factor ERF109 retards PCD and improves salt tolerance in plant. AB - BACKGROUND: The ultimate goal of this work was to detect the role of transcription factors (TFs) concordantly expressed with genes related to programmed cell death (PCD) during PCD and salt stress. This work was based on the hypothesis that TFs and their driven genes likely co-express under different stimuli. The conserved superfamily ethylene responsive factor (AP2/ERF) draw attention of the present study as it participates in the response to biotic and abiotic stimuli as well as to program cell death (PCD). RESULTS: RNA-Seq analysis was done for tobacco (N. benthamiana) leaves exposed to oxalic acid (OA) at 20 mM for 0, 2, 6, 12 and 24 h to induce PCD. Genes up-regulated after 2 h of OA treatment with known function during PCD were utilized as landmarks to select TFs with concordant expression. Knockdown mutants of these TFs were generated in tobacco via virus induced gene silencing (VIGS) in order to detect their roles during PCD. Based on the results of PCD assay, knockout (KO) T-DNA insertion mutants of Arabidopsis as well as over-expression lines of two selected TFs, namely ERF109 and TFIID5, analogs to those in tobacco, were tested under salt stress (0, 100, 150 and 200 mM NaCl). CONCLUSIONS: Results of knockdown mutant tobacco cells confirmed the influence of these two TFs during PCD. Knockout insertion mutants and over-expression lines indicated the role of ERF109 in conferring salt tolerance in Arabidopsis. PMID- 27716055 TI - TLR9 mediates S. aureus killing inside osteoblasts via induction of oxidative stress. AB - BACKGROUND: Staphylococcus aureus is the principle causative pathogen of osteomyelitis and implant-associated bone infections. It is able to invade and to proliferate inside osteoblasts thus avoiding antibiotic therapy and the host immune system. Therefore, development of alternative approaches to stimulate host innate immune responses could be beneficial in prophylaxis against S. aureus infection. TLR9 is the intracellular receptor which recognizes unmethylated bacterial CpG-DNA and activates immune cells. Synthetic CpG-motifs containing oligodeoxynucleotide (CpG-ODNs) mimics the stimulatory effect of bacterial DNA. RESULTS: Osteoblast-like SAOS-2 cells were pretreated with CpG-ODN type-A 2216, type-B 2006, or negative CpG-ODN 2243 (negative control) 4 h before infection with S. aureus isolate EDCC 5055 (=DSM 28763). Intracellular bacteria were streaked on BHI plates 4 h and 20 h after infection. ODN2216 as well as ODN2006 but not ODN2243 were able to significantly inhibit the intracellular bacterial growth because about 31 % as well as 43 % of intracellular S. aureus could survive the pretreatment of SAOS-2 cells with ODN2216 or ODN2006 respectively 4 h and 20 h post-infection. RT-PCR analysis of cDNAs from SAOS-2 cells showed that pretreatment with ODN2216 or ODN2006 stimulated the expression of TLR9. Pretreatment of SAOS-2 cells with ODN2216 or ODN2006 but not ODN2243 managed to induce reactive oxygen species (ROS) production inside osteoblasts as measured by flow cytometry analysis. Moreover, treating SAOS-2 cells with the antioxidant Diphenyleneiodonium (DPI) obviously reduced S. aureus killing ability of TLR9 agonists mediated by oxidative stress. CONCLUSIONS: In this work we demonstrated for the first time that CPG-ODNs have inhibitory effects on S. aureus survival inside SAOS-2 osteoblast-like cell line. This effect was attributed to stimulation of TLR9 and subsequent induction of oxidative stress. Pretreatment of infected SAOS-2 cells with ROS inhibitors resulted in the abolishment of the CPG ODNs killing effects. PMID- 27716056 TI - Histone modifications facilitate the coexpression of bidirectional promoters in rice. AB - BACKGROUND: Bidirectional gene pairs are highly abundant and mostly co-regulated in eukaryotic genomes. The structural features of bidirectional promoters (BDPs) have been well studied in yeast, humans and plants. However, the underlying mechanisms responsible for the coexpression of BDPs remain understudied, especially in plants. RESULTS: Here, we characterized chromatin features associated with rice BDPs. Several unique chromatin features were present in rice BDPs but were missing from unidirectional promoters (UDPs), including overrepresented active histone marks, canonical nucleosomes and underrepresented H3K27me3. In particular, overrepresented active marks (H3K4ac, H4K12ac, H4K16ac, H3K4me2 and H3K36me3) were truly overrepresented in type I BDPs but not in the other two BDPs, based on a Kolmogorov-Smirnov test. CONCLUSIONS: Our analyses indicate that active marks (H3K4ac, H4K12ac, H4K16ac, H3K4me3, H3K9ac and H3K27ac) may coordinate with repressive marks (H3K27me3 and H3K9me1/3) to build a unique chromatin structure that favors the coregulation of bidirectional gene pairs. Thus, our findings help to enhance the understanding of unique epigenetic mechanisms that regulate bidirectional gene pairs and may improve the manipulation of gene pairs for crop bioengineering. PMID- 27716058 TI - Ascertainment bias from imputation methods evaluation in wheat. AB - BACKGROUND: Whole-genome genotyping techniques like Genotyping-by-sequencing (GBS) are being used for genetic studies such as Genome-Wide Association (GWAS) and Genomewide Selection (GS), where different strategies for imputation have been developed. Nevertheless, imputation error may lead to poor performance (i.e. smaller power or higher false positive rate) when complete data is not required as it is for GWAS, and each marker is taken at a time. The aim of this study was to compare the performance of GWAS analysis for Quantitative Trait Loci (QTL) of major and minor effect using different imputation methods when no reference panel is available in a wheat GBS panel. RESULTS: In this study, we compared the power and false positive rate of dissecting quantitative traits for imputed and not imputed marker score matrices in: (1) a complete molecular marker barley panel array, and (2) a GBS wheat panel with missing data. We found that there is an ascertainment bias in imputation method comparisons. Simulating over a complete matrix and creating missing data at random proved that imputation methods have a poorer performance. Furthermore, we found that when QTL were simulated with imputed data, the imputation methods performed better than the not-imputed ones. On the other hand, when QTL were simulated with not-imputed data, the not-imputed method and one of the imputation methods performed better for dissecting quantitative traits. Moreover, larger differences between imputation methods were detected for QTL of major effect than QTL of minor effect. We also compared the different marker score matrices for GWAS analysis in a real wheat phenotype dataset, and we found minimal differences indicating that imputation did not improve the GWAS performance when a reference panel was not available. CONCLUSIONS: Poorer performance was found in GWAS analysis when an imputed marker score matrix was used, no reference panel is available, in a wheat GBS panel. PMID- 27716057 TI - Acquisition and loss of virulence-associated factors during genome evolution and speciation in three clades of Bordetella species. AB - BACKGROUND: The genus Bordetella consists of nine species that include important respiratory pathogens such as the 'classical' species B. bronchiseptica, B. pertussis and B. parapertussis and six more distantly related and less extensively studied species. Here we analyze sequence diversity and gene content of 128 genome sequences from all nine species with focus on the evolution of virulence-associated factors. RESULTS: Both genome-wide sequence-based and gene content-based phylogenetic trees divide the genus into three species clades. The phylogenies are congruent between species suggesting genus-wide co-evolution of sequence diversity and gene content, but less correlated within species, mainly because of strain-specific presence of many different prophages. We compared the genomes with focus on virulence-associated genes and identified multiple clade specific, species-specific and strain-specific events of gene acquisition and gene loss, including genes encoding O-antigens, protein secretion systems and bacterial toxins. Gene loss was more frequent than gene gain throughout the evolution, and loss of hundreds of genes was associated with the origin of several species, including the recently evolved human-restricted B. pertussis and B. holmesii, B. parapertussis and the avian pathogen B. avium. CONCLUSIONS: Acquisition and loss of multiple genes drive the evolution and speciation in the genus Bordetella, including large scale gene loss associated with the origin of several species. Recent loss and functional inactivation of genes, including those encoding pertussis vaccine components and bacterial toxins, in individual strains emphasize ongoing evolution. PMID- 27716059 TI - IL-23 plasma level is strongly associated with CMV status and reactivation of CMV in renal transplant recipients. AB - BACKGROUND: Cytomegalovirus seropositivity is an independent risk factor for atherosclerosis in patients with ESRD. Donor CMV seropositivity is associated with higher graft loss. Dendritic cells, macrophages and Th17 lymphocytes are defined as producers of IL-23. IL-23 is thought to be involved in the promotion of Th17 cell polarization. Latent CMV-induced Th17 might be involved in the pathogenesis of CMV infection in patients with ESRD. We aimed to evaluate associations of Th17-dependent cytokines with ESRD, CMV status and post transplant outcome in kidney transplantation. RESULTS: IL-21 plasma levels were similar in patients and healthy controls (p = 0.47), whereas IL-9 (p = 0.02) and IL-23 (p < 0.0001) levels were significantly higher in ESRD patients. CMV seronegative (p = 0.002) and -seropositive (p < 0.001) patients had significantly higher IL-23 plasma levels than controls. CMV-seropositive patients showed excessively higher IL-23 (p < 0.001) plasma levels than CMV-seronegative patients. Patients with post-transplant CMV reactivation had higher IL-23 plasma levels than patients without CMV reactivation (p = 0.025). CONCLUSIONS: Our results indicate that latent CMV induces IL-23. IL-23 might be an inflammatory mediator of latent CMV infection in patients with ESRD and predisposes patients for post-transplant CMV reactivation. PMID- 27716060 TI - miR-27b shapes the presynaptic transcriptome and influences neurotransmission by silencing the polycomb group protein Bmi1. AB - BACKGROUND: MicroRNAs (miRNAs) are short non-coding RNAs that are emerging as important post-transcriptional regulators of neuronal and synaptic development. The precise impact of miRNAs on presynaptic function and neurotransmission remains, however, poorly understood. RESULTS: Here, we identify miR-27b-an abundant neuronal miRNA implicated in neurological disorders-as a global regulator of the presynaptic transcriptome. miR-27b influences the expression of three quarters of genes associated with presynaptic function in cortical neurons. Contrary to expectation, a large majority of these genes are up-regulated by miR 27b. This stimulatory effect is mediated by miR-27b-directed silencing of several transcriptional repressors that cooperate to suppress the presynaptic transcriptome. The strongest repressive activity appears to be mediated by Bmi1, a component of the polycomb repressive complex implicated in self-renewal of neural stem cells. miR-27b knockdown leads to reduced synaptogenesis and to a marked decrease in neural network activity, which is fully restored by RNAi mediated silencing of Bmi1. CONCLUSIONS: We conclude that silencing of Bmi1 by miR-27b relieves repression of the presynaptic transcriptome and supports neurotransmission in cortical networks. These results expand the repressive activity of Bmi1 to genes involved in synaptic function and identify a unique post-transcriptional circuitry that stimulates expression of synaptic genes and promotes synapse differentiation. PMID- 27716061 TI - Identification of manganese efficiency candidate genes in winter barley (Hordeum vulgare) using genome wide association mapping. AB - BACKGROUND: Manganese (Mn) has several essential functions in plants, including a role as cofactor in the oxygen evolving complex (OEC) of photosystem II (PSII). Manganese deficiency is a major plant nutritional disorder in winter cereals resulting in significant yield reductions and winter kill in more severe cases. Among the winter cereals, genotypes of winter barley are known to differ considerably in tolerance to Mn deficiency, but the genes controlling the Mn deficiency trait remains elusive. RESULTS: Experiments were conducted using 248 barley varieties, cultivated in six distinct environments prone to induce Mn deficiency. High-throughput phenotyping for Mn deficiency was performed by chlorophyll a (Chl a) fluorescence analysis to quantify the quantum yield efficiency of PSII. High-throughput phenotyping in combination with ICP-OES based multi-element analyses allowed detection of marker-trait associations by genome wide association (GWA) mapping. Several key candidate genes were identified, including PSII subunit proteins, germin like proteins and Mn superoxide dismutase. The putative roles of the encoded proteins in Mn dependent metabolic processes are discussed. CONCLUSIONS: Fifty-four candidate genes were identified by Chl a fluorescence phenotyping and association genetics. Tolerance of plants to Mn deficiency, which is referred to as Mn efficiency, appeared to be a complex trait involving many genes. Moreover, the trait appeared to be highly dependent on the environmental conditions in field. This study provides the basis for an improved understanding of the parameters influencing Mn efficiency and is valuable in future plant breeding aiming at producing new varieties with improved tolerance to cultivation in soil prone to induce Mn deficiency. PMID- 27716062 TI - Genotyping of whole genome amplified reduced representation libraries reveals a cryptic population of Culicoides brevitarsis in the Northern Territory, Australia. AB - BACKGROUND: The advent of genotyping by Next Generation Sequencing has enabled rapid discovery of thousands of single nucleotide polymorphism (SNP) markers and high throughput genotyping of large populations at an affordable cost. Genotyping by sequencing (GBS), a reduced representation library sequencing method, allows highly multiplexed sequencing of genomic subsets. This method has limitations for small organisms with low amounts of genomic DNA, such as the bluetongue virus (BTV) vectors, Culicoides midges. RESULTS: This study employed the GBS method to isolate SNP markers de novo from whole genome amplified Culicoides brevitarsis genomic DNA. The individuals were collected from regions representing two different Australian patterns of BTV strain distribution: the Northern Territory (NT) and the east coast. We isolated 8145 SNPs using GBS. Phylogenetic analysis conducted using the filtered 3263 SNPs revealed the presence of a distinct C. brevitarsis sub-population in the NT and this was confirmed by analysis of mitochondrial DNA. Two loci showed a very strong signal for selection and were unique to the NT population. Bayesian analysis with STRUCTURE indicated a possible two-population cluster. CONCLUSIONS: The results suggest that genotyping vectors with high density markers in combination with biological and environmental data is useful. However, more extensive sampling over a wider spatial and temporal range is needed. The presence of sub-structure in populations and loci under natural selection indicates the need for further investigation of the role of vectors in shaping the two Australian systems of BTV transmission. The described workflow is transferable to genotyping of small, non model organisms, including arthropod vectors of pathogens of economic and medical importance. PMID- 27716063 TI - Measurement of adherence in a randomised controlled trial of a complex intervention: supported self-management for adults with learning disability and type 2 diabetes. AB - BACKGROUND: Reporting adherence to intervention delivery and uptake is a detailed way of describing what was actually delivered and received, in comparison to what was intended. Measuring and reporting adherence is not routinely done well in complex interventions. The OK Diabetes trial (ISRCTN41897033) aimed to develop and subsequently test the feasibility of implementing a supported self-management intervention in adults with a learning disability and type 2 diabetes. A key study objective was to develop a measure of adherence to the intervention. METHODS: We conducted a systematic review of published literature, extracting data from included papers using a standardised proforma. We undertook a narrative synthesis of papers to determine the form and content of methods for adherence measurement for self-management interventions in this population that had already been developed. We used the framework and data extraction form developed for the review as the basis for an adherence measurement tool that we applied in the OK Diabetes trial. RESULTS: The literature review found variability in the quality and content of adherence measurement and reporting, with no standardised approach. We were able to develop an adherence measure based upon the review, and populate it with data collected during the OK Diabetes trial. The adherence tool proved satisfactory for recording and measuring adherence in the trial. CONCLUSION: There remains a need for a standardised approach to adherence measurement in the field of complex interventions. We have shown that it is possible to produce a simple, feasible measure for assessing adherence in the OK Diabetes trial. PMID- 27716064 TI - Changes in selected metabolic parameters in patients over 65 receiving hydrochlorothiazide plus amiloride, atenolol or placebo in the MRC elderly trial. AB - BACKGROUND: Treatment of hypertension reduces incidence of stroke, myocardial infarction and heart failure perhaps partly by controlling different metabolic parameters. There is limited information regarding the changes in potassium, sodium, weight, cholesterol and glucose levels in patients using anti hypertensives. This study aimed to determine changes in potassium, sodium, glucose, cholesterol, weight, urea and urate levels in patients using anti hypertensives. Furthermore, to describe these changes and differences between the atenolol, hydrochlorothiazide plus amiloride and placebo arms of the Medical Research Council (MRC) elderly randomised controlled trial. METHODS: Patients were randomly allocated to one of the three treatment arms. Measurements were taken at baseline, end of year one and end of year two in 4396 subjects. Linear Mixed Models (LMM) were used to determine the longitudinal profiles of sodium, potassium, weight, cholesterol, glucose, urea and urate. Estimates of changes within groups and difference between groups were obtained. RESULTS: Patients randomised to receive hydrochlorothiazide + amiloride experienced a significantly greater mean reduction in potassium, sodium and weight compared to placebo at end of year one - mean differences in change -0.18 mmol/L, (95 % CI: -0.21, -0.15); 1.45 mmol/L, (95 % CI: -1.62, -1.29) and -0.46 kgs (95 % CI: -0.73, -0.20) respectively, and greater increases in cholesterol, urea and urate - mean differences in change 0.16 mmol/L, (95 % CI: 0.10,0.22); 0.77 mmol/L, (95 % CI: 0.68, 0.87) and 53.10 MUmol/L, (95 % CI: 49.35, 56.85) respectively. Changes were in the same direction but smaller in the atenololarm except for potassium and weight (increases). No group differences in glucose were found. CONCLUSION: Results were in line with expectation except for lack of change in glucose in the hydrochlorothiazide + amiloride arms. PMID- 27716065 TI - CYP79D enzymes contribute to jasmonic acid-induced formation of aldoximes and other nitrogenous volatiles in two Erythroxylum species. AB - BACKGROUND: Amino acid-derived aldoximes and nitriles play important roles in plant defence. They are well-known as precursors for constitutive defence compounds such as cyanogenic glucosides and glucosinolates, but are also released as volatiles after insect feeding. Cytochrome P450 monooxygenases (CYP) of the CYP79 family catalyze the formation of aldoximes from the corresponding amino acids. However, the majority of CYP79s characterized so far are involved in cyanogenic glucoside or glucosinolate biosynthesis and only a few have been reported to be responsible for nitrogenous volatile production. RESULTS: In this study we analysed and compared the jasmonic acid-induced volatile blends of two Erythroxylum species, the cultivated South American crop species E. coca and the African wild species E. fischeri. Both species produced different nitrogenous compounds including aliphatic aldoximes and an aromatic nitrile. Four isolated CYP79 genes (two from each species) were heterologously expressed in yeast and biochemically characterized. CYP79D62 from E. coca and CYP79D61 and CYP79D60 from E. fischeri showed broad substrate specificity in vitro and converted L phenylalanine, L-isoleucine, L-leucine, L-tryptophan, and L-tyrosine into the respective aldoximes. In contrast, recombinant CYP79D63 from E. coca exclusively accepted L-tryptophan as substrate. Quantitative real-time PCR revealed that CYP79D60, CYP79D61, and CYP79D62 were significantly upregulated in jasmonic acid treated Erythroxylum leaves. CONCLUSIONS: The kinetic parameters of the enzymes expressed in vitro coupled with the expression patterns of the corresponding genes and the accumulation and emission of (E/Z)-phenylacetaldoxime, (E/Z)-indole 3-acetaldoxime, (E/Z)-3-methylbutyraldoxime, and (E/Z)-2-methylbutyraldoxime in jasmonic acid-treated leaves suggest that CYP79D60, CYP79D61, and CYP79D62 accept L-phenylalanine, L-leucine, L-isoleucine, and L-tryptophan as substrates in vivo and contribute to the production of volatile and semi-volatile nitrogenous defence compounds in E. coca and E. fischeri. PMID- 27716066 TI - Maize plants can enter a standby mode to cope with chilling stress. AB - BACKGROUND: European Flint maize inbred lines are used as a source of adaptation to cold in most breeding programs in Northern Europe. A deep understanding of their adaptation strategy could thus provide valuable clues for further improvement, which is required in the current context of climate change. We therefore compared six inbreds and two derived Flint x Dent hybrids for their response to one-week at low temperature (10 degrees C day/7 or 4 degrees C night) during steady-state vegetative growth. RESULTS: Leaf growth was arrested during chilling treatment but recovered fast upon return to warm temperature, so that no negative effect on shoot biomass was measured. Gene expression analyses of the emerging leaf in the hybrids suggest that plants maintained a 'ready-to grow' state during chilling since cell cycle genes were not differentially expressed in the division zone and genes coding for expansins were on the opposite up-regulated in the elongation zone. In photosynthetic tissues, a strong reduction in PSII efficiency was measured. Chilling repressed chlorophyll biosynthesis; we detected accumulation of the precursor geranylgeranyl chlorophyll a and down-regulation of GERANYLGERANYL REDUCTASE (GGR) in mature leaf tissues. Excess light energy was mostly dissipated through fluorescence and constitutive thermal dissipation processes, rather than by light-regulated thermal dissipation. Consistently, only weak clues of xanthophyll cycle activation were found. CO2 assimilation was reduced by chilling, as well as the expression levels of genes encoding phosphoenolpyruvate carboxylase (PEPC), pyruvate orthophosphate dikinase (PPDK), and the small subunit of Rubisco. Accumulation of sugars was correlated with a strong decrease of the specific leaf area (SLA). CONCLUSIONS: Altogether, our study reveals good tolerance of the photosynthetic machinery of Northern European maize to chilling and suggests that growth arrest might be their strategy for fast recovery after a mild stress. PMID- 27716067 TI - Improving measurement-invariance assessments: correcting entrenched testing deficiencies. AB - BACKGROUND: Factor analysis historically focused on measurement while path analysis employed observed variables as though they were error-free. When factor- and path-analysis merged as structural equation modeling, factor analytic notions dominated measurement discussions - including assessments of measurement invariance across groups. The factor analytic tradition fostered disregard of model testing and consequently entrenched this deficiency in measurement invariance assessments. DISCUSSION: Applying contemporary model testing requirements to the so-called configural model initiating invariance assessments will improve future assessments but a substantial backlog of deficient assessments remain to be overcome. This article summarizes the issues, demonstrates the problem using a recent example, illustrates a superior model assessment strategy, and documents disciplinary entrenchment of inadequate testing as exemplified by the journal Organizational Research Methods. Employing the few methodologically and theoretically best, rather than precariously multiple, indicators of latent variables increases the likelihood of achieving properly causally specified structural equation models capable of displaying measurement invariance. Just as evidence of invalidity trumps reliability, evidence of configural model misspecification trumps invariant estimates of misspecified coefficients.

AB - BACKGROUND: The rate for upper gastrointestinal (UGI) cancers, and especially the rate for gastric cancer, varies from country to country and from region to region within country. In Turkey, the incidence of gastric cancer varies widely among regions due to the diverse cultures and accompanying food habits of the population. This study aimed to determine the endoscopic frequency of esophageal and gastric cancers and the usefulness of alarm symptoms in diagnosing gastric cancer in subjects undergoing endoscopy in northeastern Turkey. METHODS: This retrospective study was based on hospital records, reviewing the records of patients who had underdone esophago-gastro-duodenal (EGD) video endoscopy at two general hospitals in Erzurum. From July 2010 to January 2013, 25,037 patients from Erzurum underwent EGD procedures under either intravenous sedation or local anesthesia. Classifications of UGI cancer, based on location of the tumor, were defined as esophageal, cardia, cardia and fundus or corpus or all of these, corpus, corpus and antrum, and antrum. Metastasis was studied in 659 patients diagnosed with cancer. RESULTS: Throughout the study, 1,007 biopsy samples were reported as malignant tumors (719 gastric, 276 esophageal, and 12 duodenal cancers). The study considered the gastric cancer population under age 46, which included 99 (13.8 %) patients. Among them, the distribution of UGI cancer by age was as follows: under age 26 years, 9 patients (0.9 %); age 26-35 years, 30 patients (3 %); and age 36-45 years, 60 patients (6 %). Overall, 298 patients (298/1007, 29.6 %) presented with localized disease, and 361 patients (35.9 %) had distant metastases at the time of diagnosis. CONCLUSIONS: We determined that UGI cancer patients are observed more frequently in northeastern Turkey than in western Turkey, Europe, and the USA. We believe that alarm symptoms and endoscopic scanning programs require new, region-specific criteria to diagnose UGI cancers in this region. For the patient groups with these different characteristics, we believe that new scanning, follow-up, and treatment strategies are needed that take into consideration differences in the histopathology of the tumors, their localization, and the patients' ages. TRIAL REGISTRATION: There is registration number. This study is "retrospective study". This study is "retrospectively registered". PMID- 27716068 TI - Developing physical activity counselling in primary care through participatory action approach. AB - BACKGROUND: Many adults are insufficiently physically active for health. Counselling is the main method to promote physical activity (PA) in primary care but often implemented inadequately. The aim of this study was to increase health professionals' i) know-how about health-related PA and PA counselling, ii) implementation and quality of PA counselling, iii) familiarity with and use of Physical Activity Prescription (PAP), iv) internal and external collaboration and v) use of electronic patient record system in PA counselling. METHODS: Four Finnish health centres participated. Each nominated a working group for reaching the goals through a 6-month development work, which was supported with monthly tutorials by the research group. The outcome evaluation of the development work included 19 variables, which reflected the five goals and were assessed before (baseline) and after the development work (follow-up). Variable-specific differences in proportions (%) and their 95 % confidence intervals (CI) between the time points indicated change. The measures were questionnaires to the health professionals (N = 75 at baseline and N = 80 at follow-up) and patients (N = 441 and N = 431), professionals' record sheets on patient visits (N = 1008 and N = 1000), and telephone interviews to external partners (N = 48 and N = 28). The process was evaluated with the extent the working group members participated in the development work and with the implementation of development actions. Assessment was based on meeting minutes of tutorials and working group meetings. RESULTS: Health professionals' familiarity with PAP (questionnaire, change 39 % points; 95 % CI 26.5 to 52.5) and use of PAP (questionnaire, 32 %-points; 95 % CI 18.9 to 45.1 and record sheet, 4 %-points; 95 % CI 2.7 to 5.3) increased. A greater proportion of professionals had agreed in their working unit on using PAP (questionnaire, 32 %-points; 95 % CI 20.3 to 43.7) and used PAP as a referral to other health professionals (record sheet, 1 %-point; 95 % CI 0.3 to 1.7). Also the know-how of PA and PA counselling showed improvement but not statistically significantly. The working group members participated unevenly in the development work and had difficulties in allocating time for the work. This was seen in limited number of actions implemented. CONCLUSIONS: The study was able to achieve some improvements in the familiarity with and use of PAP and to lesser extent in the know-how of health-related PA and PA counselling. To observe changes in other goals, which targeted more at organisational, inter-professional and multi sectorial level, may have required more long-term actions. PMID- 27716070 TI - A potential marker of bare metal stent restenosis: monocyte count - to- HDL cholesterol ratio. AB - BACKGROUND: Oxidation and inflammation play significant roles in the pathogenesis of coronary artery diseases. Monocyte count to high-density lipoprotein (HDL) cholesterol ratio (MHR) is a new marker and has revealed as an indicator of inflammation in the literature. The present study aimed to search the effect of MHR on in-stent restenosis (ISR) in patients with stable or unstable angina pectoris undergoing bare-metal stent (BMS) implantation. METHODS: A total of 468 consecutive stable or unstable angina pectoris patients (mean age 60.3 +/- 10.1 and 70 % men) who had undergone successful BMS implantation were included the study. Serum samples were obtained before the procedure. RESULTS: The mean period between two coronary angiography procedures was 14 +/- 7.9 months. The baseline MHR levels were significantly higher in patients that had ISR (odds ratio, 3.64; 95 % confidence interval, 2.45- 4.84; P < 0.001). Stent diameter, the time between the two coronary angiographic studies, uric acid and MHR levels emerged as independent predictors of ISR. CONCLUSIONS: Our results indicate that elevated MHR is an independent and powerful predictor of ISR in patients with stable or unstable angina pectoris who underwent successful BMS implantation. PMID- 27716071 TI - Effectiveness of cyclosporine as a treatment for steroid-resistant Cronkhite Canada syndrome; two case reports. AB - BACKGROUND: Cronkhite-Canada syndrome (CCS) is a rare non-inherited disorder, characterized by gastrointestinal polyposis and ectodermal changes. The pathophysiology remains unclear. Treatment with corticosteroids is considered the mainstay treatment because of its high efficacy. However, some patients have steroid-resistant CCS. The therapeutic strategy for steroid-resistant CCS is not yet established. We report two cases with steroid-resistant CCS that were effectively treated with cyclosporine (CyA). We evaluated the therapeutic strategy for steroid-resistant CCS based on reviews of previous reports. CASE PRESENTATION: Our patients with CCS were first treated with prednisolone. No clinical response was noted, and treatment with CyA was initiated. After beginning CyA treatment, both clinical symptoms and polyposis markedly improved. Up to the present, 55 cases of CCS treated with corticosteroids and their response were reported. Out of the 57 patients, including our 2 cases, 9 (16 %) did not respond clinically to corticosteroids. In 7 of the 9 steroid-resistant cases, the prognosis after corticosteroids treatment was described. In 5 of the 7 steroid-resistant cases, immunosuppressive treatments induced remission. In 4 of these 5 cases, moreover, the key drug of treatments was calcineurin inhibitor. CONCLUSIONS: Treatment with calcineurin inhibitor, such as CyA, could be a potential option for steroid-resistant CCS. PMID- 27716072 TI - Wnt signaling contributes to vascular calcification by induction of matrix metalloproteinases. AB - BACKGROUND: Vascular calcifications such as arteriosclerosis, which is characterized by a calcificiation of the tunica media, represent major comorbidities e.g. in patients with chronic kidney disease (CKD). An essential step during the development of arteriosclerosis is the transdifferentiation/calcification of vascular smooth muscle cells (VSMC) resembling osteogenesis. The matrix metalloproteinases (MMP)-2 and -9 were shown to promote these VSMC calcifications and their inhibition is of therapeutic value to prevent arteriosclerosis in preclinical studies. Aiming for an understanding of the underlying regulatory mechanisms of MMPs we here investigated, if the MMP mediated VSMC calcification involves altered signaling of the Wnt pathway, which is known to impact osteogenesis. METHODS: We used an experimental in vitro model of vascular calcification. Transdifferentiation/calcification of murine VSMC was induced by elevated calcium and phosphorus levels. Calcification was assessed by calcium and alkaline phosphatase measurements. Activation/activity of the gelatinases MMP-2 and MMP-9 was assessed by conversion of fluorescence-labelled substrates. Activation of the Wnt pathway was analysed by a reporter gene assay. RESULTS: Besides pro-calcifying culture conditions, also activation of Wnt signaling by a specific agonist (under normal culture conditions) stimulated VSMC calcification accompanied by enhanced expression and secretion of the gelatinases MMP-2 and -9. Vice versa, recombinant MMP-2 and -9 induced a time-delayed activation of Wnt signaling after 72 h in VSMC but showed no direct effects after 24-48 h. These effects were blocked by pharmacological inhibition of MMPs or of Wnt signaling. CONCLUSIONS: Our study suggests that the pro-calcifying environment in CKD induces Wnt signaling in VSMC which in turn contributes to the induction of MMPs which then foster the development of arteriosclerosis. Thus, besides MMP inhibition, the inhibition of Wnt signaling in VSMC might represent a therapeutic target for the prevention of vascular calcifications. PMID- 27716073 TI - Male-specific association between MT-ND4 11719 A/G polymorphism and ulcerative colitis: a mitochondria-wide genetic association study. AB - BACKGROUND: Ulcerative colitis (UC) is a chronic inflammatory disorder of still unknown pathogenesis. Increasing evidence indicates that alterations in mitochondrial respiration and thus adenosine triphosphate (ATP) production are involved. This may contribute to mucosal energy deficiency and subsequently intestinal barrier malfunction, which is accepted to be a major hallmark of UC. Genetic alterations of the mitochondrial genome are one cause of mitochondrial dysfunction. However, less is known about mitochondrial gene polymorphisms in UC. Therefore, we aimed at identifying genetic associations between mitochondrial polymorphisms and UC. METHODS: German UC cases (n = 1062) and German healthy controls (n = 3030) were genotyped using the Affymetrix Genome-Wide Human SNP Array 6.0. The primary association analysis was to test for associations between mitochondrial single nucleotide polymorphisms (SNPs) and UC using Fisher's exact test in the total sample and stratified by sex. In addition, we tested for associations between mitochondrial haplogroups and UC and for interactions between the most promising mitochondrial SNPs and nuclear SNPs. An independent set of German subjects with 1625 UC cases and 3575 controls was used for replication. RESULTS: We identified a genetic association between the MT-ND4 11719 A/G polymorphism and UC in the subgroup of males (rs2853495; odds ratio, 1.40; 95 % confidence interval, 1.13 to 1.73; p = 0.002). This association was replicated in the second independent cohort. In the association analysis based on mitochondrial haplogroups the lowest p values were reached for haplogroups HV and T (p = 0.029 and 0.035). Haplogroup HV is determined by the mitochondrial 11719 A/G polymorphism. Accordingly, this association was only found in the subgroup of males (p = 0.009). CONCLUSIONS: For the first time, we observed an association between the MT-ND4 11719 A/G polymorphism and UC. The gene MT-ND4 encodes for a subunit of the mitochondrial electron transport chain complex I, which is pivotal for ATP production and might therefore contribute to mucosal energy deficiency. The male-specific association indicates differences between males and females concerning the impact of mitochondrial gene polymorphisms on the development of UC. Further investigations of the functional mechanism underlying this association and the relevance of the gender-specificity are highly warranted. PMID- 27716074 TI - Methods for network meta-analysis of continuous outcomes using individual patient data: a case study in acupuncture for chronic pain. AB - BACKGROUND: Network meta-analysis methods, which are an extension of the standard pair-wise synthesis framework, allow for the simultaneous comparison of multiple interventions and consideration of the entire body of evidence in a single statistical model. There are well-established advantages to using individual patient data to perform network meta-analysis and methods for network meta analysis of individual patient data have already been developed for dichotomous and time-to-event data. This paper describes appropriate methods for the network meta-analysis of individual patient data on continuous outcomes. METHODS: This paper introduces and describes network meta-analysis of individual patient data models for continuous outcomes using the analysis of covariance framework. Comparisons are made between this approach and change score and final score only approaches, which are frequently used and have been proposed in the methodological literature. A motivating example on the effectiveness of acupuncture for chronic pain is used to demonstrate the methods. Individual patient data on 28 randomised controlled trials were synthesised. Consistency of endpoints across the evidence base was obtained through standardisation and mapping exercises. RESULTS: Individual patient data availability avoided the use of non-baseline-adjusted models, allowing instead for analysis of covariance models to be applied and thus improving the precision of treatment effect estimates while adjusting for baseline imbalance. CONCLUSIONS: The network meta analysis of individual patient data using the analysis of covariance approach is advocated to be the most appropriate modelling approach for network meta-analysis of continuous outcomes, particularly in the presence of baseline imbalance. Further methods developments are required to address the challenge of analysing aggregate level data in the presence of baseline imbalance. PMID- 27716075 TI - Culprit-only versus staged complete revascularization for patients with ST segment elevation myocardial infarction and Multivessel disease: a retrospective cohort study. AB - BACKGROUND: Multivessel disease (MVD) is common in patients with ST-segment elevation myocardial infarction (STEMI), but optimal treatment management remains undetermined. METHODS: In this retrospective cohort study, 602 consecutive STEMI patients with MVD were enrolled between January 1, 2010 and October 1, 2014. Three hundred and eighty-two patients underwent culprit-only revascularization and 220 underwent staged complete revascularization. Primary end points were a composite of cardiac mortality or nonfatal reinfarction. RESULTS: The mean duration of follow-up was 35 months (12-71 months). Following multivariate analysis, staged complete revascularization was associated with a lower rate of the composite of cardiac mortality or nonfatal reinfarction [HR: 0.430, 95 % CI: 0.197-0.940, P = 0.034] and unplanned repeat revascularization [HR: 0.343, 95 % CI: 0.166-0.708, P = 0.004] compared with culprit-only revascularization. CONCLUSIONS: Compared with culprit-only revascularization, staged complete revascularization significantly reduced the rate of the composite of cardiac mortality or nonfatal reinfarction, and the need for unplanned repeat revascularization. PMID- 27716076 TI - Smartphone use habits of anesthesia providers during anesthetized patient care: a survey from Turkey. AB - BACKGROUND: Smartphones are used in many areas of anesthesia practice. However, recent editorial articles have expressed concerns about smartphone uses in the operating room for non-medical purposes. We performed a survey to learn about the smartphone use habits and views of Turkish anesthesia providers. METHODS: A questionnaire consisting of 14 questions about smartphone use habits during anesthesia care was sent anesthesia providers. RESULTS: In November-December 2015, a total of 955 participants answered our survey with 93.7 % of respondents responding that they used smartphones during the anesthetized patient care. Phone calls (65.4 %), messaging (46.4 %), social media (35.3 %), and surfing the internet (33.7 %) were the most common purposes. However, 96.7 % of respondents indicated that smartphones were either never or seldom used during critical stages of anesthesia. Most respondents (87.3 %) stated that they were never distracted because of smartphone use; however, 41 % had witnessed their collagues in such a situation at least once. CONCLUSIONS: According to the results of the survey, smartphones are used in the operating room often for non-medical purposes. Distraction remains a concern but evidence-based data on whether restrictions to smartphone use are required are not yet available. PMID- 27716077 TI - Changes in plasma ghrelin and leptin levels in patients with peptic ulcer and gastritis following eradication of Helicobacter pylori infection. AB - BACKGROUND: Helicobacter pylori (H. pylori) infection and eradication therapy have been known to influence gastric ghrelin and leptin secretion, which may lead to weight gain. However, the exact relationship between plasma ghrelin/leptin levels and H. pylori infection has remained controversial. The aim of this study was to investigate plasma ghrelin and leptin levels in H. pylori-positive and negative patients, to compare the two levels of the hormones before and after H. pylori eradication, and to examine the correlation between body mass index (BMI) and active ghrelin or leptin levels, as well as that between atrophic pattern and active ghrelin or leptin levels. METHODS: Seventy-two H. pylori-positive patients who underwent upper gastrointestinal endoscopy, 46 diagnosed as having peptic ulcer and 26 as atrophic gastritis, were enrolled. Control samples were obtained from 15 healthy H. pylori-negative volunteers. The extent of atrophic change of the gastric mucosa was assessed endoscopically. Body weight was measured and blood was collected before and 12 weeks after H. pylori eradication therapy. Blood samples were taken between 8 and 10 AM after an overnight fast. RESULTS: Plasma ghrelin levels were significantly lower in H. pylori-positive patients than in H. pylori-negative patients. In particular, plasma active ghrelin levels were significantly lower in patients with gastritis compared with patients with peptic ulcer. Plasma ghrelin levels decreased after H. pylori eradication in both peptic ulcer and gastritis patients, while plasma leptin levels increased only in peptic ulcer patients. Plasma leptin levels and BMI were positively correlated, and active ghrelin levels and atrophic pattern were weakly negatively correlated in peptic ulcer patients. CONCLUSION: H. pylori infection and eradication therapy may affect circulating ghrelin/leptin levels. This finding suggests a relationship between gastric mucosal injury induced by H. pylori infection and changes in plasma ghrelin and leptin levels. PMID- 27716078 TI - A case of asystole from carotid sinus hypersensitivity during patient positioning for thyroidectomy. AB - BACKGROUND: We present a case of a patient with multinodular goiter disease who suffered asystole during head hyperextension for surgical positioning on the operational table. CASE PRESENTATION: Manipulation of carotid sinus may trigger bradycardia or even asystole even in patients without prior history of carotid sinus hypersensitivity. The time proximity between patient positioning and asystole, the late responsiveness to atropine, the immediate increase of heart rate after head elevation and the lack of any other trigger factor or prior history support the hypothesis of carotid sinus syndrome. CONCLUSIONS: Head hyperextension during surgical positioning is not only responsible for jeopardizing blood flow to spinal cord and brainstem but may trigger reflexes, as well, even in patients without prior neck pathology. PMID- 27716079 TI - Adjusting for overdispersion in piecewise exponential regression models to estimate excess mortality rate in population-based research. AB - BACKGROUND: In population-based cancer research, piecewise exponential regression models are used to derive adjusted estimates of excess mortality due to cancer using the Poisson generalized linear modelling framework. However, the assumption that the conditional mean and variance of the rate parameter given the set of covariates x i are equal is strong and may fail to account for overdispersion given the variability of the rate parameter (the variance exceeds the mean). Using an empirical example, we aimed to describe simple methods to test and correct for overdispersion. METHODS: We used a regression-based score test for overdispersion under the relative survival framework and proposed different approaches to correct for overdispersion including a quasi-likelihood, robust standard errors estimation, negative binomial regression and flexible piecewise modelling. RESULTS: All piecewise exponential regression models showed the presence of significant inherent overdispersion (p-value <0.001). However, the flexible piecewise exponential model showed the smallest overdispersion parameter (3.2 versus 21.3) for non-flexible piecewise exponential models. CONCLUSION: We showed that there were no major differences between methods. However, using a flexible piecewise regression modelling, with either a quasi-likelihood or robust standard errors, was the best approach as it deals with both, overdispersion due to model misspecification and true or inherent overdispersion. PMID- 27716080 TI - Collagenous colitis presenting as spontaneous perforation in an 80 year old woman: Report of a Case. AB - BACKGROUND: Perforation of the colon occurring during or shortly following colonoscopy or barium enema is a rare complication of collagenous colitis (CC). "Spontaneous" perforation in CC, in which no instigating factor is identified, is even less common, with only five cases reported to date. We report herein an additional case of spontaneous perforation in previously undiagnosed CC and review the clinical and pathological features of previously reported cases. CASE PRESENTATION: An 80 year old woman presented to the emergency department with abdominal pain preceded by approximately one month of frequent non-bloody diarrhea. Abdominal CT showed parietal thickening of the colon at the splenic flexure with pneumatosis and signs of perforation. Segmental resection was performed. Pathologic examination showed the microscopic findings typical of CC complicated by several deep ulcers and perforation. One day following discharge from hospital abdominal pain and frequent non-bloody diarrhea recurred. The patient was managed conservatively and treated with oral budesonide with resulting resolution of symptoms. CONCLUSIONS: Spontaneous perforation is a rare and serious complication of CC. All patients to date have been female. In contrast to procedure-related perforation, which favors the right colon, spontaneous perforation in CC has in all cases involved the left colon. Knowledge of spontaneous perforation as a potential complication of previously undiagnosed CC may be helpful in the evaluation and management of patients presenting with colonic perforation, especially those with risk factors for CC. PMID- 27716081 TI - Thoracic epidural analgesia reduces gastric microcirculation in the pig. AB - BACKGROUND: Thoracic epidural analgesia (TEA) is used for pain relief during and after abdominal surgery, but the effect of TEA on the splanchnic microcirculation remains debated. We evaluated whether TEA affects splanchnic microcirculation in the pig. METHODS: Splanchnic microcirculation was assessed in nine pigs prior to and 15 and 30 min after induction of TEA. Regional blood flow was assessed by neutron activated microspheres and changes in microcirculation by laser speckle contrast imaging (LSCI). RESULTS: As assessed by LSCI 15 min following TEA, gastric arteriolar flow decreased by 22 % at the antrum (p = 0.020) and by 19 % at the corpus (p = 0.029) of the stomach. In parallel, the microcirculation decreased by 19 % at the antrum (p = 0.015) and by 20 % at the corpus (p = 0.028). Reduced arteriolar flow and microcirculation at the antrum was confirmed by a reduction in microsphere assessed regional blood flow 30 min following induction of TEA (p = 0.048). These manifestations took place along with a drop in systolic blood pressure (p = 0.030), but with no significant change in mean arterial pressure, cardiac output, or heart rate. CONCLUSION: The results indicate that TEA may have an adverse effect on gastric arteriolar blood flow and microcirculation. LSCI is a non-touch technique and displays changes in blood flow in real-time and may be important for further evaluation of the concern regarding the effect of thoracic epidural anesthesia on gastric microcirculation in humans. TRIAL REGISTRATIONS: Not applicable, non-human study. PMID- 27716083 TI - Intraoperative echocardiographic delineation of the high take-off coronary ostia during an extensive surgical repair of the bicuspid aortic valve and dilated sinotubular junction: a case report. AB - BACKGROUND: This study reports the efficacy of intraoperative transesophageal echocardiography (TEE) for evaluation of high take-off coronary ostia and proximal coronary arterial flows as an alternative to preoperative coronary angiography. CASE PRESENTATION: In a 65-year old male undergoing the bicuspid aortic valve (BAV) repair and the extensive remodeling of dilated sinus and tubular junction, and preoperative coronary angiography were unsuccessfully completed due to an allergic reaction to the contrast medium. Intraoperative TEE by employing various 3-dimensional volume images of coronary ostia and Doppler tracings of the coronary arterial flows enabled a thorough pre-procedural evaluation of the high take-off coronary arteries and post-procedural evaluation by confirming the absence of any compromise in coronary arterial flow. CONCLUSION: In the present case, intraoperative application of various TEE imaging modalities enabled comprehensive evaluation of high-taking off coronary artery, as an alternative to preoperative coronary angiography, in a patient undergoing an extensive aortic valve and aortic root repair procedure. PMID- 27716082 TI - First do no harm: pain relief for the peripheral venous cannulation of adults, a systematic review and network meta-analysis. AB - BACKGROUND: Peripheral venous cannulation is an everyday practice in hospitals, which many adults find painful. However, anaesthesia for cannulation is usually only offered to children. Inadequate pain relief is not only unpleasant for patients but may cause anxiety about further treatment and deter patients from seeking medical care in the future. The aim of this study is to discover the most effective local anaesthetic for adult peripheral venous cannulation and to find out how the pain of local anaesthetic application compares with that of unattenuated cannulation. METHODS: These aims are addressed through a systematic review, network meta-analysis and random-effects meta-analysis. Searching covered 12 databases including MEDLINE and EMBASE from 1990 to August 2015. The main included study design was RCTs. The primary outcome measure is self-reported pain, measured on a 100 mm visual analogue scale. RESULTS: The systematic review found 37 includable studies, 27 of which were suitable for network meta-analysis and two for random-effects meta-analysis. The results of the network meta analysis indicate that none of the 17 anaesthetic considered had a very high probability of being the most effective when compared to each other; 2 % lidocaine had the highest probability (44 %). When the anaesthetics were compared to no treatment, the network meta-analysis showed that again 2 % lidocaine was estimated to be the most effective (mean difference -25.42 (95 % CI -32.25, 18.57). Other members of the 'caine' family were also estimated to be more effective than no treatment as were Ametop(r), EMLA(r) and Rapydan(r) patch. The meta-analysis compared the pain of anaesthetic application with the unattenuated pain of cannulation. This found that all applications of local anaesthetic were less painful than cannulation without local anaesthetic. In particular a 1 % lidocaine injection was estimated to be -12.97 (95 % CI -15.71, -10.24) points (100 mm VAS) less painful than unattenuated cannulation. CONCLUSIONS: The pain of peripheral venous cannulation in adults can be successfully treated. The pain of application of any local anaesthetic is less than that of unattenuated cannulation. Local anaesthetic prior to cannulation should become normal practice and a marker of high quality care. PROTOCOL REGISTRATION: The protocol for the larger study was registered with PROSPERO no. CRD42012002093 . PMID- 27716084 TI - Quinine induced simvastatin toxicity through cytochrome inhibition - a case report. AB - BACKGROUND: Nocturnal leg cramps are painful, involuntary muscle contractions commonly seen in elderly. While mostly harmless, they can severely impair quality of life and often disrupt sleep. Adverse drug effects may be responsible for a fraction of nocturnal leg cramps but often go unrecognized, resulting in additional prescribing intended to deal with adverse effects that might be better addressed by reduction, substitution, or discontinuation of the offending agent. CASE PRESENTATION: An 87 year old female presented as outpatient in family medicine with nocturnal leg cramps which had been present for five years and increasingly burdened her quality of life. She had been using quinine 200 mg once daily for symptomatic relief but the cramps kept returning with increasing intensity. During clinical examination we found neither structural nor neurological or metabolic disorders that explained her symptoms. When doing a medication analysis, we found that she was taking a statin together with quinine. Quinine is a cytochrome P450 isoenzyme 3A4 inhibitor, the very enzyme which is involved in the metabolism of most statins. Therefore the use of both substances simultaneously increases blood levels of the statin thereby increasing the risk of side effects including symptomatic myopathy and myalgia. After discontinuing both medications, the patient was, and remained, symptom free. CONCLUSION: This case report describes a possible medication interaction that has rarely been noted in literature. PMID- 27716085 TI - Clinical significance of incidental [18 F]FDG uptake in the gastrointestinal tract on PET/CT imaging: a retrospective cohort study. AB - BACKGROUND: The frequency and clinically important characteristics of incidental (18)F-fluorodeoxyglucose ([18 F]FDG) positron emission tomography (PET) uptake in the gastrointestinal tract (GIT) on PET/CT imaging in adults remain elusive. METHODS: All PET/CT reports from 1/1/2000 to 12/31/2009 at a single tertiary referral center were reviewed; clinical information was obtained from cases with incidental (18)F-FDG uptake in the GIT, with follow-up through October, 2012. RESULTS: Of the 41,538 PET/CT scans performed during the study period, 303 (0.7 %) had incidental GIT uptake. The most common indication for the PET/CT order was cancer staging (226 cases, 75 %), with 74 % for solid and 26 % for hematologic malignancies. Of those with solid malignancy, only 51 (17 %) had known metastatic disease. The most common site of GIT uptake was the colon, and of the 240 cases with colonic uptake, the most common areas of uptake were cecum (n = 65), sigmoid (n = 60), and ascending colon (n = 50). Investigations were pursued for the GIT uptake in 147 cases (49 %), whereas 51 % did not undergo additional studies, largely due to advanced disease. There were 73 premalignant colonic lesions diagnosed in 56 cases (tubular adenoma, n = 36; tubulovillous adenoma with low grade dysplasia, n = 27; sessile serrated adenoma, n = 4; tubulovillous adenoma with high grade dysplasia, n = 3; villous adenoma, n = 3), and 20 cases with newly diagnosed primary colon cancer. All 20 (100 %) patients with malignant colonic lesions had a focal pattern of [18 F]FDG uptake. Among cases with a known pattern of [18 F]FDG uptake, 98 % of those with premalignant lesions had focal [18 F]FDG uptake. Eighteen (90 %) of the cases with newly diagnosed colon cancer were not known to have metastatic disease of their primary tumor. Areas of incidental uptake in the ascending colon had the greatest chance (42 %) of being malignant and premalignant lesions than in any other area. CONCLUSION: Focality of uptake is highly sensitive for malignant and premalignant lesions of the GIT. In patients without metastatic disease, incidental focal [18]FDG uptake in the GIT on PET/CT imaging warrants further evaluation. PMID- 27716086 TI - Association of CD247 (CD3zeta) gene polymorphisms with T1D and AITD in the population of northern Sweden. AB - BACKGROUND: T1D and AITD are autoimmune disorders commonly occurring in the same family and even in the same individual. The genetic contribution to these disorders is complex making uncovering of susceptibility genes very challenging. The general aim of this study was to identify loci and genes contributing to T1D/AITD susceptibility. Our strategy was to perform linkage and association studies in the relatively genetically homogenous population of northern Sweden. We performed a GWLS to find genomic regions linked to T1D/AITD in families from northern Sweden and we performed an association study in the families to test for association between T1D/AITD and variants in previously published candidate genes as well as a novel candidate gene, CD247. METHODS: DNA prepared from 459 individuals was used to perform a linkage and an association study. The ABI PRISM Linkage Mapping Set v2.5MD10 was employed for an initial 10-cM GWLS, and additional markers were added for fine mapping. Merlin was used for linkage calculations. For the association analysis, a GoldenGate Custom Panel from Illumina containing 79 SNPs of interest was used and FBAT was used for association calculations. RESULTS: Our study revealed linkage to two previously identified chromosomal regions, 4q25 and 6p22, as well as to a novel chromosomal region, 1q23. The association study replicated association to PTPN22, HLA-DRB1, INS, IFIH1, CTLA4 and C12orf30. Evidence in favor of association was also found for SNPs in the novel susceptibility gene CD247. CONCLUSIONS: Several risk loci for T1D/AITD identified in published association studies were replicated in a family material, of modest size, from northern Sweden. This provides evidence that these loci confer disease susceptibility in this population and emphasizes that small to intermediate sized family studies in this population can be used in a cost-effective manner for the search of genes involved in complex diseases. The linkage study revealed a chromosomal region in which a novel T1D/AITD susceptibility gene, CD247, is located. The association study showed association between T1D/AITD and several variants in this gene. These results suggests that common susceptibility genes act in concert with variants of CD247 to generate genetic risk for T1D/AITD in this population. PMID- 27716087 TI - Small dense low-density lipoprotein cholesterol was associated with future cardiovascular events in chronic kidney disease patients. AB - BACKGROUND: Cardiovascular disease (CVD) is often comorbid with chronic kidney disease (CKD). Small low-density lipoprotein cholesterol (sdLDL-C) has also been found to increase risk for CVD. The goal of the present study was to determine the nature of the relationship between sdLDL-C concentration and CVD in patients with CKD. METHODS: One-hundred and forty-five subjects (113 men and 32 women) with CKD (Stage 3 and Stage 4) participated this retrospective study. The concentration of sdLDL-C was measured in samples from 145 CKD patients between 2010 and 2012 during a four-year follow-up period. RESULTS: A total of eight fatal cardiovascular events (CVs) and 46 nonfatal CVs were registered in the four year follow-up period. Multivariate Cox regression analysis showed that sdLDL-C [1.278, 95 % (1.019-1.598)] and sdLDL-C/LDL-C [2.456, 95 % (1.421-15.784)], at final observation, were independent risks of CVs. A Kaplan-Meier survival analysis showed that patients with sdLDL-C >38 mg/dl (logrank: 4.375, P = 0.037), and sdLDL-C/LDL-C ratio >0.3 levels (logrank: 11.94, P = 0.018) were at increased risk for CVs. CONCLUSION: The results of this study indicated that for patients suffering CKD, a significant relationship exists between an elevated sdLDL-C concentration and the risk of cardiovascular disease. PMID- 27716088 TI - eRegistries: indicators for the WHO Essential Interventions for reproductive, maternal, newborn and child health. AB - BACKGROUND: Electronic health registries - eRegistries - can systematically collect relevant information at the point of care for reproductive, maternal, newborn and child health (RMNCH). However, a suite of process and outcome indicators is needed for RMNCH to monitor care and to ensure comparability between settings. Here we report on the assessment of current global indicators and the development of a suite of indicators for the WHO Essential Interventions for use at various levels of health care systems nationally and globally. METHODS: Currently available indicators from both household and facility surveys were collated through publicly available global databases and respective survey instruments. We then developed a suite of potential indicators and associated data points for the 45 WHO Essential Interventions spanning preconception to newborn care. Four types of performance indicators were identified (where applicable): process (i.e. coverage) and outcome (i.e. impact) indicators for both screening and treatment/prevention. Indicators were evaluated by an international expert panel against the eRegistries indicator evaluation criteria and further refined based on feedback by the eRegistries technical team. RESULTS: Of the 45 WHO Essential Interventions, only 16 were addressed in any of the household survey data available. A set of 216 potential indicators was developed. These indicators were generally evaluated favourably by the panel, but difficulties in data ascertainment, including for outcome measures of cause specific morbidity and mortality, were frequently reported as barriers to the feasibility of indicators. Indicators were refined based on feedback, culminating in the final list of 193 total unique indicators: 93 for preconception and antenatal care; 53 for childbirth and postpartum care; and 47 for newborn and small and ill baby care. CONCLUSIONS: Large gaps exist in the availability of information currently collected to support the implementation of the WHO Essential Interventions. The development of this suite of indicators can be used to support the implementation of eRegistries and other data platforms, to ensure that data are utilised to support evidence-based practice, facilitate measurement and accountability, and improve maternal and child health outcomes. PMID- 27716089 TI - Absence of convincing evidence of Coxiella burnetii infection in Chile: a cross sectional serosurvey among healthy adults in four different regions. AB - BACKGROUND: Coxiella burnetii is an important zoonotic pathogen of global distribution. Still, in most parts of South America including Chile, systematic epidemiological data are lacking. The presented study aims to determine the seroprevalence of Coxiella burnetii antibodies in healthy adults of four different regions in Chile. METHODS: A cross-sectional study was performed, which included healthy adults living in rural and urban areas of four cities located in different regions in northern, central, and southern Chile. In urban sectors, households were chosen by double stratified random sampling, while in rural areas convenience sampling was performed. Serum specimens were taken and screened for the presence of IgG antibodies against C. burnetii phase II antigen using a commercial ELISA kit. Positive and indeterminate results were confirmed by a reference laboratory using indirect immunofluorescence assay (IFA). RESULTS: A total of 1112 individuals were included. Of those, 8 were positive by ELISA, but only one sample was confirmed using IFA. Statistical analysis for population freedom from disease revealed a high probability that C. burnetii was absent in our study population. CONCLUSION: Our work provides the first epidemiological data on human Q fever in Chile indicating either a very low endemicity or the absence of this pathogen in the studied areas. PMID- 27716090 TI - Seeking order amidst chaos: a systematic review of classification systems for causes of stillbirth and neonatal death, 2009-2014. AB - BACKGROUND: Each year, about 5.3 million babies die in the perinatal period. Understanding of causes of death is critical for prevention, yet there is no globally acceptable classification system. Instead, many disparate systems have been developed and used. We aimed to identify all systems used or created between 2009 and 2014, with their key features, including extent of alignment with the International Classification of Diseases (ICD) and variation in features by region, to inform the World Health Organization's development of a new global approach to classifying perinatal deaths. METHODS: A systematic literature review (CINAHL, EMBASE, Medline, Global Health, and PubMed) identified published and unpublished studies and national reports describing new classification systems or modifications of existing systems for causes of perinatal death, or that used or tested such systems, between 2009 and 2014. Studies reporting ICD use only were excluded. Data were independently double-extracted (except from non-English publications). Subgroup analyses explored variation by extent and region. RESULTS: Eighty-one systems were identified as new, modifications of existing systems, or having been used between 2009 and 2014, with an average of ten systems created/modified each year. Systems had widely varying characteristics: (i) comprehensiveness (40 systems classified both stillbirths and neonatal deaths); (ii) extent of use (systems were created in 28 countries and used in 40; 17 were created for national use; 27 were widely used); (iii) accessibility (three systems available in e-format); (iv) underlying cause of death (64 systems required a single cause of death); (v) reliability (10 systems tested for reliability, with overall Kappa scores ranging from .35-.93); and (vi) ICD alignment (17 systems used ICD codes). Regional databases were not searched, so system numbers may be underestimated. Some non-differential misclassification of systems was possible. CONCLUSIONS: The plethora of systems in use, and continuing system development, hamper international efforts to improve understanding of causes of death. Recognition of the features of currently used systems, combined with a better understanding of the drivers of continued system creation, may help the development of a truly effective global system. PMID- 27716091 TI - Entomological efficacy of durable wall lining with reduced wall surface coverage for strengthening visceral leishmaniasis vector control in Bangladesh, India and Nepal. AB - BACKGROUND: New methods for controlling sand fly are highly desired by the Visceral Leishmaniasis (VL) elimination program of Bangladesh, India and Nepal for its consolidation and maintenance phases. To support the program we investigated safety, efficacy and cost of Durable Wall Lining to control sand fly. METHODS: This multicentre randomized controlled study in Bangladesh, India and Nepal included randomized two intervention clusters and one control cluster. Each cluster had 50 households except full wall surface coverage (DWL-FWSC) cluster in Nepal which had 46 households. Ten of 50 households were randomly selected for entomological activities except India where it was 6 households. Interventions were DWL-FWSC and reduced wall surface coverage (DWL-RWSC) with DWL which covers 1.8 m and 1.5 m height from floor respectively. Efficacy was measured by reduction in sand fly density by intervention and sand fly mortality assessment by the WHO cone bioassay test at 1 month after intervention. Trained field research assistants interviewed household heads for socio-demographic information, knowledge and practice about VL, vector control, and for their experience following the intervention. Cost data was collected using cost data collection tool which was designed for this study. Statistical analysis included difference-in-differences estimate, bivariate analysis, Poisson regression model and incremental cost-efficacy ratio calculation. RESULTS: Mean sand fly density reduction by DWL-FWSC and DWL-RWSC was respectively -4.96 (95 % CI, -4.54, -5.38) and -5.38 (95 % CI, -4.89, -5.88). The sand fly density reduction attributed by both the interventions were statistically significant after adjusting for covariates (IRR = 0.277, p < 0.001 for DWL-RWSC and IRR = 0.371, p < 0.001 for DWL-FWSC). The efficacy of DWL-RWSC and DWL-FWSC on sand fly density reduction was statistically comparable (p = 0.214). The acceptability of both interventions was high. Transient burning sensations, flash on face and itching were most common adverse events and were observed mostly in Indian site. There was no serious adverse event. DWL-RWSC is cost-saving compared to DWL-FWSC. The incremental cost-efficacy ratio was -6.36, where DWL-RWSC dominates DWL-FWSC. CONCLUSIONS: DWL-RWSC intervention is safe, efficacious, cost-saving and cost effective in reducing indoor sand fly density. The VL elimination program in the Indian sub-continent may consider DWL-RWSC for sand fly control for its consolidation and maintenance phases. PMID- 27716092 TI - A deformable template method for describing and averaging the anatomical variation of the human nasal cavity. AB - BACKGROUND: Understanding airflow through human airways is of importance in drug delivery and development of assisted breathing methods. In this work, we focus on development of a new method to obtain an averaged upper airway geometry from computed tomography (CT) scans of many individuals. This geometry can be used for air flow simulation. We examine the geometry resulting from a data set consisting of 26 airway scans. The methods used to achieve this include nasal cavity segmentation and a deformable template matching procedure. METHODS: The method uses CT scans of the nasal cavity of individuals to obtain a segmented mesh, and coronal cross-sections of this segmented mesh are taken. The cross-sections are processed to extract the nasal cavity, and then thinned ('skeletonized') representations of the airways are computed. A reference template is then deformed such that it lies on this thinned representation. The average of these deformations is used to obtain the average geometry. Our procedure tolerates a wider variety of nasal cavity geometries than earlier methods. RESULTS: To assess the averaging method, key landmark points on each of the input scans as well as the output average geometry are located and compared with one another, showing good agreement. In addition, the cross-sectional area (CSA) profile of the nasal cavities of the input scans and average geometry are also computed, showing that the CSA of the average model falls within the variation of the population. CONCLUSIONS: The use of a deformable template method for aligning and averaging the nasal cavity provides an improved, detailed geometry that is unavailable without using deformation. PMID- 27716094 TI - Modulation of renal oxygenation and perfusion in rat kidney monitored by quantitative diffusion and blood oxygen level dependent magnetic resonance imaging on a clinical 1.5T platform. AB - BACKGROUND: To investigate the combined use of intravoxel incoherent motion (IVIM) diffusion-weighted (DW) and blood oxygen level dependent (BOLD) magnetic resonance imaging (MRI) to assess rat renal function using a 1.5T clinical platform. METHODS: Multiple b-value DW and BOLD MR images were acquired from adult rats using a parallel clinical coil arrangement, enabling quantitation of the apparent diffusion coefficient (ADC), IVIM-derived diffusion coefficient (D), pseudodiffusion coefficient (D*) and perfusion fraction (f), and the transverse relaxation time T2*, for whole kidney, renal cortex, and medulla. Following the acquisition of two baseline datasets to assess measurement repeatability, images were acquired following i.v. administration of hydralazine, furosemide, or angiotensin II for up to 40 min. RESULTS: Excellent repeatability (CoV <10 %) was observed for ADC, D, f and T2* measured over the whole kidney. Hydralazine induced a marked and significant (p < 0.05) reduction in whole kidney ADC, D, and T2*, and a significant (p < 0.05) increase in D* and f. Furosemide significantly (p < 0.05) increased whole kidney ADC, D, and T2*. A more variable response to angiotensin II was determined, with a significant (p < 0.05) increase in medulla D* and significant (p < 0.05) reduction in whole kidney T2* established. CONCLUSIONS: Multiparametric MRI, incorporating quantitation of IVIM DWI and BOLD biomarkers and performed on a clinical platform, can be used to monitor the acute effects of vascular and tubular modulating drugs on rat kidney function in vivo. Clinical adoption of such functional imaging biomarkers can potentially inform on treatment effects in patients with renal dysfunction. PMID- 27716093 TI - Effectiveness and safety of generic version of abacavir/lamivudine and efavirenz in treatment naive HIV-infected patients: a nonrandomized, open-label, phase IV study in Cali-Colombia, 2011-2012. AB - BACKGROUND: Generic drug policies are often associated with concerns about the quality and effectiveness of these products. Phase IV clinical trials may be a suitable design to assess the effectiveness and safety of generic drugs. The objective of this study was to describe the effectiveness and the safety of the generic abacavir/lamivudine and efavirenz in treatment-naive HIV-infected patients. METHODS: A monocentric, nonrandomized, open-label, phase IV study in treatment naive HIV-infected patients 18 years or older with indication to receive abacavir/lamivudine and efavirenz were recruited from a program that provides comprehensive outpatient consultation and continuing care. The primary end-point was to achieve viral load <40 copies/mL at 12 months after baseline to assess effectiveness. Secondary end-point of the study were 1) to asses increasing in T-CD4 lymphocytes levels as accompaniment to asses effectiveness, and 2) to assess both gastrointestinal, skin, and central nervous system symptoms, and lipid profile, cardiovascular risk, renal, and hepatic function as safety profile. Data were determined at baseline, 3, 6, and 12 months. Close clinical monitoring and pharmaceutical care were used for data collection. Wilcoxon matched-pairs signed-rank test was used to compare proportions or medians. RESULTS: Sixty patients were invited to participate in the study; 42 were enrolled and 33 completed the follow-up. Of the nine patients excluded from the study, only one was withdrawn due to adverse events. At 12 months, 31 of 42 patients (73.8 % in intention-to-treat analysis) achieved a viral load of HIV1 RNA <40 copies/mL. There was a significant increase (172 cells/mm3) in the median for CD4 T lymphocyte count. The adverse events were mild and met the safety profile for this antiretroviral regimen, mainly of central nervous system symptoms, skin rash, lipid abnormalities, and an increase of 2 % in the median of the percentage of cardiovascular risk. CONCLUSIONS: The clinical outcomes of generic version of abacavir/lamivudine and efavirenz in HIV treatment naive patients showed the expected safety and effectiveness profile of proprietary ARV drugs. TRIAL REGISTRATION: Registro Publico Cubano de Ensayos Clinicos (RPCEC) ID: RPCEC00000202 . Registered 19 November 2015. PMID- 27716095 TI - For whom is a health-promoting intervention effective? Predictive factors for performing activities of daily living independently. AB - BACKGROUND: Health-promoting interventions tailored to support older persons to remain in their homes, so-called "ageing in place" is important for supporting or improving their health. The health-promoting programme "Elderly Persons in the Risk Zone," (EPRZ) was set up for this purpose and has shown positive results for maintaining independence in activities of daily living for older persons 80 years and above at 1- and 2 year follow-ups. The aim of this study was to explore factors for maintaining independence in the EPRZ health-promoting programme. METHODS: Total of 459 participants in the original trial was included in the analysis; 345 in the programme arm and 114 in the control arm. Thirteen variables, including demographic, health, and programme-specific indicators, were chosen as predictors for independence of activities of daily living. Logistic regression was performed separately for participants in the health promotion programme and in the control arm. RESULTS: In the programme arm, being younger, living alone and self-rated lack of tiredness in performing mobility activities predicted a positive effect of independence in activities of daily living at 1 year follow-up (odds ratio [OR] 1.18, 1.73, 3.02) and 2-year, (OR 1.13, 2.01, 2.02). In the control arm, being less frail was the only predictor at 1-year follow up (OR 1.6 1.09, 2.4); no variables predicted the outcome at the 2-year follow-up. CONCLUSIONS: Older persons living alone - as a risk of ill health - should be especially recognized and offered an opportunity to participate in health-promoting programmes such as "Elderly Persons in the Risk Zone". Further, screening for subjective frailty could form an advantageous guiding principle to target the right population when deciding to whom health-promoting intervention should be offered. TRIAL REGISTRATION: The original clinical trial was registered at ClinicalTrials.gov. Identifier: NCT00877058 , April 6, 2009. PMID- 27716096 TI - The effect of intramuscular interferon beta-1a on spinal cord volume in relapsing remitting multiple sclerosis. AB - BACKGROUND: Spinal cord atrophy occurs early in multiple sclerosis (MS) and impacts disability. The therapeutic effect of interferon beta-1a (IFNbeta-1a) on spinal cord atrophy in patients with relapsing-remitting (RR) MS has not been explored. METHODS: We retrospectively identified 16 consecutive patients receiving weekly intramuscular IFNbeta-1a for 2 years [baseline age (mean +/- SD) 47.7 +/- 7.5 years, Expanded Disability Status Scale score median (range) 1.5 (0 2.5), timed 25-foot walk 4.6 +/- 0.7 seconds; time on treatment 68.3 +/- 59.9 months] and 11 sex- and age-matched normal controls (NC). The spinal cord was imaged at baseline, 1 and 2 years later with 3T MRI. C1-C5 spinal cord volume was measured by an active surface method, from which normalized spinal cord area (SCA) was calculated. RESULTS: SCA showed no change in the MS or NC group over 2 years [mean annualized difference (95 % CI) MS: -0.604 mm2 (-1.352, 0.144), p = 0.106; NC: -0.360 mm2 (-1.576, 0.855), p = 0.524]. Between group analysis indicated no differences in on-study SCA change [MS vs. NC; year 1 vs. baseline, mean annualized difference (95 % CI) 0.400 mm2 (-3.350, 2.549), p = 0.780; year 2 vs. year 1: -1.196 mm2 (-0.875, 3.266), p = 0.245; year 2 vs. baseline -0.243 mm2 (-1.120, 1.607), p = 0.712]. CONCLUSION: Established IFNbeta-1a therapy was not associated with ongoing spinal cord atrophy or any difference in the rate of spinal cord volume change in RRMS compared to NC over 2 years. These results may reflect a treatment effect. However, due to sample size and study design, these results should be considered preliminary and await confirmation. PMID- 27716097 TI - The impact of paclitaxel and carboplatin chemotherapy on the autonomous nervous system of patients with ovarian cancer. AB - BACKGROUND: Paclitaxel-based regimens are frequently associated with the development of peripheral neuropathy. The autonomous nervous system (ANS) effects, however, of this chemotherapeutic agent remain unexplored. METHODS: We investigated a group of 31 female patients with ovarian cancer receiving treatment with paclitaxel and carboplatin, as well as a group of 16 healthy age- and gender-matched healthy volunteers. All study participants completed a questionnaire and were assessed neurophysiologically at three time points (baseline, 3-4 months and 6-8 months following the onset of chemotherapy). The evaluation of the ANS included assessment of the adrenergic cardiovascular function (orthostatic hypotension-OH), parasympathetic heart innervation (30/15 ratio) and sympathetic skin response (SSR). RESULTS: At the 3-4 months ANS assessment, 19.2 % of the patients had systolic OH and the same percentage had diastolic OH, but at the 6-8 months evaluation no patient had systolic OH and only 13.8 % had diastolic OH. The values of the 30/15 ratio were significantly reduced at both time points, whereas the SSR was not affected. CONCLUSIONS: Combined paclitaxel and carboplatin chemotherapy is associated with significant effects on the parasympathetic heart innervation and occasionally with effects on the adrenergic cardiovascular reaction. The SSR remained unaffected. Physicians should be alert to the possibility of these treatment-emergent side effects, so as to monitor ANS parameters and introduce treatment modifications accordingly. Our findings however, should be validated in larger cohorts. PMID- 27716098 TI - Anxiety and depression symptoms among caregivers of care-recipients with subjective cognitive decline and cognitive impairment. AB - BACKGROUND: Caregivers of care-recipients with mild cognitive impairment (MCI) or dementia experience high caregiver burden; however, the psychiatric burden of caregivers of care-recipients with subjective cognitive decline (SCD) has not been investigated. We aimed to explore the prevalence of and risk factors for anxiety and depression symptoms among the caregivers of care-recipients with SCD and cognitive impairment. METHODS: The Hospital Anxiety and Depression Scale (HADS) was used to examine the anxiety and depression symptoms among the caregivers of 343 care-recipients (84 with SCD, 120 with MCI and 139 with dementia) treated at the Memory Clinic of Huashan Hospital in Shanghai, China from May 2012 to October 2014. A logistic regression was used to explore the factors associated with caregiver's anxiety and depression symptoms. RESULTS: In total, 26.5 % of caregivers had anxiety symptoms, and 22.4 % had depression symptoms. Totals of 17.9, 30.0 and 28.8 % of caregivers of care-recipients with SCD, MCI or dementia, respectively, had anxiety symptoms (P = 0.1140), whereas 22.6, 24.2 and 20.9 %, respectively, had depression symptoms (P = 0.8165). The risk factors for caregiver's anxiety symptoms were increased caregiver age as well as having care-recipients who were male, had higher Cohen Mansfield Agitation Inventory (CMAI) scores, and higher Geriatric Depression Scale (GDS) scores. The risk factors for caregiver's depression symptoms were increased caregiver age as well as caring for care-recipients with MCI or SCD, those with lower Toronto Empathy Questionnaire (TEQ) scores, and those with higher GDS scores. CONCLUSIONS: Caregivers of care-recipients with SCD showed the same level of depression symptoms as those of care-recipients with MCI. Caregiver's depression and anxiety symptoms were associated with their care-recipients' psychiatric and behavioral syndromes. PMID- 27716099 TI - Prevalence of intestinal parasitic infections and associated risk factors among pregnant women attending antenatal care center at Felege Hiwot Referral Hospital, northwest Ethiopia. AB - BACKGROUND: Parasitic infections affect tens of millions of pregnant women worldwide, and directly or indirectly lead to a spectrum of adverse maternal and fetal/placental effects. The objective of this study was to assess the prevalence of intestinal parasite infections and associated risk factors among pregnant women attending antenatal care center in Felege Hiwot Referral Hospital, Bahir Dar city, northwest Ethiopia. METHODS: A cross-sectional hospital based study was conducted from November 2013 to January 2014 among 384 pregnant women. Stool samples were examined for the presence of trophozoites, cysts, oocysts, and ova using direct, formal-ether sedimentation, and modified Ziehl-Neelsen techniques. RESULTS: An overall prevalence of 31.5 % intestinal parasite infections was recorded. Eight different species of intestinal parasites were found: two protozoan and six helminth species. The highest prevalence was due to Giardia lamblia (13.3 %) followed by Entamoeba histolytica/dispar (7.8 %), hookworm (5.5 %), Ascaris lumbricoides (2.9 %), Schistosoma mansoni (2.9 %), Strongyloides stercoralis (1.6 %), Taenia spp. (0.8 %), and Hymenolepis nana (0.3 %). CONCLUSIONS: A relatively high prevalence of intestinal parasite infections was observed among pregnant women. Routine stool examination and provision of health education are required for early medical intervention that would affect the pregnant mothers and their foetuses. PMID- 27716100 TI - Temporal trends of beta-haemolytic streptococcal osteoarticular infections in western Norway. AB - BACKGROUND: Beta-haemolytic streptococci are important contributors to the global burden of osteoarticular infections (OAI). Knowledge on the disease traits specific for streptococcal OAI, however, remains scarce. We wished to explore temporal trends of OAI caused by Group A Streptococci (GAS), Group B Streptococci (GBS) and Group C and G Streptococci (GCGS), and furthermore, to describe the associated host and pathogen characteristics. METHODS: All cases of microbiologically verified beta-haemolytic streptococcal OAI in Health Region Bergen, Norway, in the period 1999-2013 were retrospectively identified. Clinical data were extracted from medical records. Microbial isolates were submitted to antibiotic susceptibility testing and molecular typing. RESULTS: A total of 24 GAS, 45 GBS and 42 GCGS acute OAI were identified. The cumulative incidence of GCGS OAI, but not GAS or GBS OAI, increased significantly from the first to the last 5-year period (IRR 5.7, p = 0.0003), with the annual incidence peaking at 1.9/100 000 in 2013. GAS OAI generally produced the most acute and severe clinical presentation, whereas GBS and GCGS predominantly affected the elderly, and were significantly associated with the presence of host risk factors of systemic and focal origin, respectively. CONCLUSIONS: We found a significantly increasing incidence of GCGS OAI, likely related to the presence of host susceptibility factors, including prosthetic material and pre-existing joint disease. With an increasing application of therapeutic and diagnostic bone and joint procedures, the rising trend of OAI caused by GCGS is likely to continue. Sustained epidemiological attentiveness to GCGS seems warranted. PMID- 27716101 TI - Factors associated with clinical outcome in 25 patients with avian influenza A (H7N9) infection in Guangzhou, China. AB - BACKGROUND: Guangzhou reported its first laboratory-confirmed case of influenza A (H7N9) on January 10, 2014. A total of 25 cases were reported from the first wave of the epidemic until April 8, 2014. The fatality rate was much higher than in previous reports. The objective of the current work was to describe the clinical and epidemiological characteristics of A (H7N9) patients in Guangzhou and explore possible reasons for the high fatality rate. METHODS: Clinical and epidemiological information regarding A (H7N9) cases in Guangzhou was collected through review of medical records and field research. Data regarding clinical and laboratory features, treatment, and outcomes were extracted. RESULTS: Of the 25 patients, 84 % (21/25) had one or more underlying diseases. Fifteen patients (60.0 %) developed moderate to severe acute respiratory distress syndrome (ARDS), and 14 (56 %) died of the ARDS or multiorgan failure. Patients with longer delay between onset of illness and initiation of oseltamivir treatment were more likely to develop ARDS. Elevated C-creative protein, aspartate aminotransferase, creatine kinase, and lymphocytopenia predicted a higher risk of developing ARDS. CONCLUSIONS: The presence of underlying diseases and clinical complications predicted poor clinical outcome. Early oseltamivir treatment was associated with a reduced risk of developing ARDS. PMID- 27716102 TI - Antimicrobial susceptibility testing in predicting the presence of carbapenemase genes in Enterobacteriaceae in South Africa. AB - BACKGROUND: Carbapenem-resistant Enterobacteriaceae (CRE) is a concern in South Africa and worldwide. It is therefore important that these organisms be accurately identified for infection prevention control purposes. METHOD: In this study 1193 suspected CREs from 46 laboratories from seven provinces in South Africa were assessed to confirm the prevalence of carbapenemase genes from our referral diagnostic isolates for the period 2012 to 2015. We compared the antimicrobial susceptibility testing method used in the reference laboratory to the polymerase chain reaction (PCR) which is used as the gold standard. Organism identification and antimicrobial susceptibility testing were performed using automated systems and DNA was extracted using a crude boiling method. The presence of carbapenemase-producing genes (bla NDM, bla KPC, bla OXA-48&variants, bla GES, bla IMP and bla VIM) was screened for using a multiplex real-time PCR. RESULTS: Sixty-eight percent (n = 812) of the isolates harboured a carbapenemase producing gene; the three most common genes included: bla NDM, bla OXA 48&variants and bla VIM. Majority of the carbapenemase producing Enterobacteriaceae (CPE) isolates were Klebsiella species (71 %). The Microscan(r) Walkaway system used for the screening of carbapenemase production was 98 % sensitive with a minimal inhibitory concentration (MIC) breakpoint of less than 0.5 as susceptible for ertapenem and a low specificity (13 %). CONCLUSION: From this study we can conclude that carbapenemase-producing Enterobacteriaceae is increasing in South Africa and the use of phenotypic methods for detection of CPEs showed good sensitivity but lacked specificity. PMID- 27716104 TI - Does directly observed therapy improve tuberculosis treatment? More evidence is needed to guide tuberculosis policy. AB - BACKGROUND: Tuberculosis (TB) now ranks alongside HIV as the leading infectious disease cause of death worldwide and incurs a global economic burden of over $12 billion annually. Directly observed therapy (DOT) recommends that TB patients complete the course of treatment under direct observation of a treatment supporter who is trained and overseen by health services to ensure that patients take their drugs as scheduled. Though the current WHO End TB Strategy does not mention DOT, only "supportive treatment supervision by treatment partners", many TB programs still use it despite the fact that the has not been demonstrated to be statistically significantly superior to self-administered treatment in ensuring treatment success or cure. DISCUSSION: DOT is designed to promote proper adherence to the full course of drug therapy in order to improve patient outcomes and prevent the development of drug resistance. Yet over 8 billion dollars is spent on TB treatment each year and thousands undergo DOT for all or part of their course of treatment, despite the absence of rigorous evidence supporting the superior effectiveness of DOT over self-administration for achieving drug susceptible TB (DS-TB) cure. Moreover, the DOT component burdens patients with financial and opportunity costs, and the potential for intensified stigma. To rigorously evaluate the effectiveness of DOT and identify the essential contributors to both successful treatment and minimized patient burden, we call for a pragmatic experimental trial conducted in real-world program settings, the gold standard for evidence-based health policy decisions. It is time to invest in the rigorous evaluation of DOT and reevaluate the DOT requirement for TB treatment worldwide. Rigorously evaluating the choice of treatment supporter, the frequency of health care worker contact and the development of new educational materials in a real-world setting would build the evidence base to inform the optimal design of TB treatment protocol. Implementing a more patient-centered approach may be a wise reallocation of resources to raise TB cure rates, prevent relapse, and minimize the emergence of drug resistance. Maintaining the status quo in the absence of rigorous supportive evidence may diminish the effectiveness of TB control policies in the long run. PMID- 27716103 TI - Root morphology and seed and leaf ionomic traits in a Brassica napus L. diversity panel show wide phenotypic variation and are characteristic of crop habit. AB - BACKGROUND: Mineral nutrient uptake and utilisation by plants are controlled by many traits relating to root morphology, ion transport, sequestration and translocation. The aims of this study were to determine the phenotypic diversity in root morphology and leaf and seed mineral composition of a polyploid crop species, Brassica napus L., and how these traits relate to crop habit. Traits were quantified in a diversity panel of up to 387 genotypes: 163 winter, 127 spring, and seven semiwinter oilseed rape (OSR) habits, 35 swede, 15 winter fodder, and 40 exotic/unspecified habits. Root traits of 14 d old seedlings were measured in a 'pouch and wick' system (n = ~24 replicates per genotype). The mineral composition of 3-6 rosette-stage leaves, and mature seeds, was determined on compost-grown plants from a designed experiment (n = 5) by inductively coupled plasma-mass spectrometry (ICP-MS). RESULTS: Seed size explained a large proportion of the variation in root length. Winter OSR and fodder habits had longer primary and lateral roots than spring OSR habits, with generally lower mineral concentrations. A comparison of the ratios of elements in leaf and seed parts revealed differences in translocation processes between crop habits, including those likely to be associated with crop-selection for OSR seeds with lower sulphur-containing glucosinolates. Combining root, leaf and seed traits in a discriminant analysis provided the most accurate characterisation of crop habit, illustrating the interdependence of plant tissues. CONCLUSIONS: High throughput morphological and composition phenotyping reveals complex interrelationships between mineral acquisition and accumulation linked to genetic control within and between crop types (habits) in B. napus. Despite its recent genetic ancestry (<10 ky), root morphology, and leaf and seed composition traits could potentially be used in crop improvement, if suitable markers can be identified and if these correspond with suitable agronomy and quality traits. PMID- 27716105 TI - Prevalence and factors associated with use of herbal medicines during pregnancy among women attending postnatal clinics in Gulu district, Northern Uganda. AB - BACKGROUND: According to World Health Organization (WHO) estimates, 80 % of the population living in rural areas in developing countries depends on traditional medicine for their health needs, including use during pregnancy. Despite the fact that knowledge of potential side effects of many herbal medicines in pregnancy is limited and that some herbal products may be teratogenic, data on the extent of use of herbal medicines by women during pregnancy in the study setting is largely unknown. We determined the prevalence and factors associated with herbal medicine use during pregnancy among women attending postnatal clinics in Gulu district, Northern Uganda. METHODS: This was a descriptive cross-sectional study which involved 383 women attending postnatal care across four sites in Gulu district using quantitative and qualitative methods of data collection. A structured questionnaire was used to collect quantitative data while qualitative data were obtained using focus group discussions and key informant interviews. The selection of the study participants was by systematic sampling and the main outcome variable was the proportion of mothers who used herbal medicine. Quantitative data was coded and entered into a computerized database using Epidata 3.1. Analysis was done using Statistical Package for Social Scientists version 13, while thematic analysis was used for qualitative data. RESULTS: The prevalence of herbal medicines use during the current pregnancy was 20 % (78/383), and was commonly used in the second 23 % (18/78) and third 21 % (16/78) trimesters. The factors significantly associated with use of herbal medicines during pregnancy were perception (OR 2.18, CI 1.02-4.66), and having ever used herbal medicines during previous pregnancy (OR 2.51, CI 1.21-5.19) and for other reasons (OR 3.87, CI 1.46-10.25). CONCLUSIONS: The use of herbal medicines during pregnancy among women in Gulu district is common, which may be an indicator for poor access to conventional western healthcare. Perception that herbal medicines are effective and having ever used herbal medicines during previous pregnancy were associated with use of herbal medicines during current pregnancy. This therefore calls for community sensitization drives on the dangers of indiscriminate use of herbal medicine in pregnancy, as well as integration of trained traditional herbalists and all those community persons who influence the process in addressing the varied health needs of pregnant women. PMID- 27716106 TI - In vivo functional and molecular characterization of the Penicillin-Binding Protein 4 (DacB) of Pseudomonas aeruginosa. AB - BACKGROUND: Community and nosocomial infections by Pseudomonas aeruginosa still create a major therapeutic challenge. The resistance of this opportunist pathogen to beta-lactam antibiotics is determined mainly by production of the inactivating enzyme AmpC, a class C cephalosporinase with a regulation system more complex than those found in members of the Enterobacteriaceae family. This regulatory system also participates directly in peptidoglycan turnover and recycling. One of the regulatory mechanisms for AmpC expression, recently identified in clinical isolates, is the inactivation of LMM-PBP4 (Low-Molecular-Mass Penicillin-Binding Protein 4), a protein whose catalytic activity on natural substrates has remained uncharacterized until now. RESULTS: We carried out in vivo activity trials for LMM-PBP4 of Pseudomonas aeruginosa on macromolecular peptidoglycan of Escherichia coli and Pseudomonas aeruginosa. The results showed a decrease in the relative quantity of dimeric, trimeric and anhydrous units, and a smaller reduction in monomer disaccharide pentapeptide (M5) levels, validating the occurrence of D,D carboxypeptidase and D,D-endopeptidase activities. Under conditions of induction for this protein and cefoxitin treatment, the reduction in M5 is not fully efficient, implying that LMM-PBP4 of Pseudomonas aeruginosa presents better behaviour as a D,D-endopeptidase. Kinetic evaluation of the direct D,D-peptidase activity of this protein on natural muropeptides M5 and D45 confirmed this bifunctionality and the greater affinity of LMM-PBP4 for its dimeric substrate. A three-dimensional model for the monomeric unit of LMM-PBP4 provided structural information which supports its catalytic performance. CONCLUSIONS: LMM-PBP4 of Pseudomonas aeruginosa is a bifunctional enzyme presenting both D,D carboxypeptidase and D,D-endopeptidase activities; the D,D-endopeptidase function is predominant. Our study provides unprecedented functional and structural information which supports the proposal of this protein as a potential hydrolase autolysin associated with peptidoglycan maturation and recycling. The fact that mutant PBP4 induces AmpC, may indicate that a putative muropeptide-subunit product of the DD-EPase activity of PBP4 could be a negative regulator of the pathway. This data contributes to understanding of the regulatory aspects of resistance to beta-lactam antibiotics in this bacterial model. PMID- 27716107 TI - "That was intense!" Spirituality during childbirth: a mixed-method comparative study of mothers' and fathers' experiences in a public hospital. AB - BACKGROUND: While spirituality is well described in end-of-life care literature, research on its place in the delivery room remains largely limited to mother oriented qualitative studies focusing on life-threatening situations (e.g., high risk pregnancies). Our aim was to compare mothers' and fathers' spirituality during childbirth. METHODS: A mixed methods questionnaire was developed from our childbirth-related spirituality categorization and distributed to all parents of newborns, 12-24 h postpartum, over 45 consecutive days. Paired-sample t-tests and qualitative thematic analysis were used to compare mothers and fathers. Multiple linear regressions identified factors associated with their respective global scores (vaginal and cesarean deliveries separately). RESULTS: The global scores for mothers (38.6/50) and fathers (37.2/50) were similarly high (N = 197; p = 0.001). Highest-ranked ("respect", "moral responsibility", "beauty of life", "gratitude") and lowest-ranked spiritual themes ("prayer", "greater than self") were in agreement. Fathers scored higher on "fragility of life" (p = 0.006) and mothers on "self-accomplishment" (p<0.001), "letting go" (p<0.001), and "meaningfulness" (p = 0.003). "Admission of baby in neonatal unit" was associated with higher global score for both mothers and fathers. Other factors also increased fathers' (witnessing a severe tear) and mothers' scores (birthplace outside Canada; for vaginal deliveries, religious belonging and longer pushing stage). CONCLUSION: These first quantitative data on the prevalence of spirituality during childbirth highlight a high score for both parents, among a non-selected public hospital population. Spirituality emerges not only from unordinary situations but from any childbirth as an "intensification of the human experience". Significant differences for some spiritual themes indicate the need to consider the spirituality of both parents. PMID- 27716108 TI - The therapist's role in the implementation of internet-based cognitive behavioural therapy for patients with depression: study protocol. AB - BACKGROUND: Internet-based Cognitive Behavioural Therapy (iCBT) for the treatment of depressive disorders is innovative and promising. Various studies have demonstrated large effect sizes up to 2.27, but implementation in routine practice lags behind. Mental health therapists play a significant role in the uptake of internet-based interventions. Therefore, it is interesting to study factors that influence the therapists in whether they apply internet-based therapy or not. This study, as part of the European implementation project MasterMind, aims to identity the factors that promote or hinder therapists in the use of iCBT in depression care. METHODS/DESIGN: The uptake of iCBT by therapists in routine mental health care practice for the treatment of depression will be evaluated by a mixed method approach, to provide an understanding of the implementation factors (quantitative), and to ascertain the facilitating and hindering factors in the involvement of therapists in the implementation of iCBT (qualitative). The involvement of therapists in the implementation of iCBT is analysed following the RE-AIM framework on the five dimensions Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance. This enables us to evaluate the reach of therapists, the impact of iCBT on depression care, the extent to which therapists adopt iCBT, the extent to which iCBT is delivered as intended, and how iCBT can be maintained over time. DISCUSSION: The results will provide valuable insight into the role of therapists in the implementation of iCBT for depression in secondary mental health care settings. They will result in concrete recommendations for how therapists can be facilitated in implementing and up-scaling iCBT for depression.

PMID- 27716110 TI - Metformin in prevention and treatment of antipsychotic induced weight gain: a systematic review and meta-analysis. AB - BACKGROUND: Most antipsychotics are associated with weight gain and other metabolic complications. Several randomized trials have shown metformin to be effective, but this still hasn't been included in clinical guidelines on managing antipsychotic induced weight gain. METHODS: All double blind placebo controlled trials assessing the efficacy of metformin in the treatment of antipsychotic induced weight gain were included. Cochrane Central Register of Controlled Trials (CENTRAL) and MEDLINE were searched for the period January 2000-December 2015. Meta-analysis was carried out using the random effects model. RESULTS: Meta analysis of 12 published studies with a total of 743 patients found that in patients treated with antipsychotics, metformin treatment resulted in significantly better anthropometric and metabolic parameters than placebo. The mean change in weight was -3.27 kg (95 % CI -4.66 to -1.89) (Z = 4.64, p < 0.001). Metformin compared to placebo resulted in significant reduction in BMI [ 1.13 kg/m2 (95 % CI -1.61 to -0.66)] and insulin resistance index [-1.49 (95 % CI -2.40 to -0.59)] but not fasting blood sugar [-2.48 mg/dl (95 % CI -5.54 to 0.57]. CONCLUSION: This meta-analysis confirms that metformin is effective in treating antipsychotic induced weight gain in patients with schizophrenia or schizoaffective disorder. PMID- 27716111 TI - Case report: Aqueous and Vitreous amino-acid concentrations in a patient with maple syrup urine disease operated on rhegmatogenous retinal detachment. AB - BACKGROUND: Maple syrup urine disease (MSUD) is a rare metabolic disorder, affecting the metabolism of branched chain amino-acids (Valine, Leukine, Isoleukine). We present a rare case of rhegmatogenous retinal detachment (RRD) in a MSUD patient. CASE PRESENTATION: We performed amino acid analysis of aqueous humour, vitreous and serum samples obtained during surgery from a 24 year old female MSUD patient successfully operated on RRD. Serum values for a-amino butyric acid, valine, isoleucine, leucine, tyrosine, phenylalanine, ornithine and histidine were low, while values for citrulline, methionine and lysine were borderline low, all attributed to the patient's special diet. Serum glutamate was above normal, probably due to the breakdown of glutamine to glutamate. In the aqueous and vitreous the amino acids implicated in MSUD (Valine, Leukine Isoleukine), were within normal range. Glutamate was absent in the vitreous and presented low levels in the aqueous. Glutamate has been reported to play an important role in retinal damage. Elevated glutamate levels have been reported in vitreous specimens from patients subjected to vitrectomy or buckling surgery for RRD. In MSUD, glutamate has been implicated in the pathogenesis of brain damage. Low levels of glutamate have been observed in the cerebellum of experimental MSUD animals, as well as postmortem brain tissue from a child that died of leucine intoxication. The reduction was attributed to the elevation of a-ketoisocaproic which reverses the net direction of nitrogen flow. It could be argued that this could impact on amino acid concentration in aqueous and vitreous fluids. CONCLUSIONS: Although no definite conclusions can be drawn by this extremely rare case, the low vitreous and aqueous levels of Glutamate is an interesting finding. Further studies are needed to provide a better insight in the role of amino acids as neurotransmitters in the human eye in health and disease. PMID- 27716112 TI - Accommodative changes after SMILE for moderate to high myopia correction. AB - BACKGROUND: To investigate accommodative response and accommodative lag changes after femtosecond laser small incision lenticule extraction (SMILE) for moderate to high myopia correction. METHODS: A total of 32 eyes of 32 patients with no strabismus who underwent SMILE were enrolled in this prospective clinical study. The accommodative response was obtained viewing monocularly with spherical equivalent refractive error corrected, using an open-field autorefractor at different stimulus levels (2.00D, 2.50D, 3.00D, 4.00D and 5.00D) for the right eye before a standard SMILE surgery and at 1-month follow-up after surgery. RESULTS: The mean age of the patients were 23.34 +/- 2.90 years and the mean preoperative manifest refraction spherical equivalent was -5.74 +/- 1.98 diopters. Significant differences were detected in both preoperative and postoperative accommodative responses to different stimulus levels (P < 0.001). Multiple linear regression model analysis revealed preoperative manifest refractive spherical equivalent (P = 0.006) and preoperative accommodative lag (P = 0.04) showed a significant impact on postoperative accommodative lag. CONCLUSIONS: This is the first report of accommodative changes after SMILE. Our preliminary results showed that a decrease in postoperative accommodative lag that might be related to the relief of the visual discomfort symptom. PMID- 27716114 TI - Histopathology and treatment of a huge overhanging filtering bleb. AB - BACKGROUND: The giant filtering bleb encroaching onto the corneal surface is a rare occurrence in our and other's clinical experience (Kapoor and Syed, Int. Ophthalmol 31(5):403-404, 2011), even in patients having had a trabeculectomy with mitomycin C, and how it developed is debated. In this paper, we report a patient who developed a huge overhanging filtering bleb after trabeculectomy, and present our intraoperative photographs, histopathology and immunohistochemistry results. CASE PRESENTATION: A 62-year-old female visited our hospital due to the giant filtering bleb encroaching onto the corneal surface which was about 6 mm * 8 mm * 3 mm. We dissected the filtering bleb from the cornea and present the histopathology and immunohistochemistry results of it. CONCLUSION: The results from histopathology and immunohistochemistry in this study are consistent with the filtering cicatrix hypothesis. However, our finding that the overhanging blebs had tight connections with the corneal tissue or corneoscleral limbus, rather than simply leaning on it, might be highly related to their development and still needs to be further studied. PMID- 27716113 TI - Predictive factors of dropout from inpatient treatment for anorexia nervosa. AB - BACKGROUND: Patients with severe Anorexia Nervosa (AN) whose condition is life threatening or who are not receiving adequate ambulatory care are hospitalized. However, 40 % of these patients leave the hospital prematurely, without reaching the target weight set in the treatment plan, and this can compromise outcome. This study set out to explore factors predictive of dropout from hospital treatment among patients with AN, in the hope of identifying relevant therapeutic targets. METHODS: From 2009 to 2011, 180 women hospitalized for AN (DSM-IV diagnosis) in 10 centres across France were divided into two groups: those under 18 years (when the decision to discharge belongs to the parents) and those aged 18 years and over (when the patient can legally decide to leave the hospital). Both groups underwent clinical assessment using the Morgan & Russell Global Outcome State questionnaire and the Eating Disorders Examination Questionnaire (EDE-Q) for assessment of eating disorder symptoms and outcome. Psychological aspects were assessed via the evaluation of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS). Socio-demographic data were also collected. A number of factors identified in previous research as predictive of dropout from hospital treatment were tested using stepwise descending Cox regressions. RESULTS: We found that factors predictive of dropout varied according to age groups (being under 18 as opposed to 18 and over). For participants under 18, predictive factors were living in a single-parent family, severe intake restriction as measured on the "dietary restriction" subscale of the Morgan & Russell scale, and a low patient-reported score on the EDE-Q "restraint concerns" subscale. For those over 18, dropout was predicted from a low depression score on the HADS, low level of concern about weight on the EDE-Q subscale, and lower educational status. CONCLUSION: To prevent dropout from hospitalization for AN, the appropriate therapeutic measures vary according to whether patients are under or over 18 years of age. Besides the therapeutic adjustments required in view of the factors identified, the high dropout rate raises the issue of resorting more frequently to compulsory care measures among adults. PMID- 27716115 TI - Relationship between negative symptoms and neurocognitive functions in adolescent and adult patients with first-episode schizophrenia. AB - BACKGROUND: This study aimed to explore differences in links between negative symptoms and neurocognitive deficits in adolescent and adult patients with first episode schizophrenia. Schizophrenia is a mental disorder often characterized by positive and negative symptoms, reduced emotional expression, excitatory status, and poor cognitive ability. The severity of negative symptoms in patients with schizophrenia was reported to be more related to poor quality of life, weak functional ability, and heavy burden from families than with the severity of positive symptoms. Previous studies suggested correlations between the severity of negative symptoms in patients with schizophrenia and neurocognitive deficits. METHODS: This study included 92 patients (33 adolescents and 59 adults) with first-episode schizophrenia and 57 healthy people matched by age and education level. Neurocognitive functions and clinical symptoms were assessed using a standardized questionnaire. RESULTS: Patients with first-episode schizophrenia showed neurocognitive deficits in most neuropsychological assessments compared with healthy people. With the variable of education level controlled, the negative factor score of adolescent patients with first-episode schizophrenia was strongly correlated with more time spent in part 1 (r = .646) and part 2 (r = .663) of the trail making test, and moderately correlated to more perseverative errors (r = .425) of the Wisconsin card sorting test and fewer correct trials 2 (r = -.425) of the continuous performance test. However, no such correlations were found in adult patients. CONCLUSIONS: This study indicated significant correlations between negative symptoms and most neurocognitive functions in patients with first-episode schizophrenia, with a stronger correlation in adolescent patients.

PMID- 27716116 TI - Data in longitudinal randomised controlled trials in cancer pain: is there any loss of the information available in the data? Results of a systematic literature review and guideline for reporting. AB - BACKGROUND: Given the prevalence of untreated pain among cancer patients, there have been calls for more and better research in the domain. Increasingly, calls for less waste and more optimal use of trial data collected are being made. Waste of data includes non-optimal statistical analysis and non-presentation of interpretable effect size as a measure of effectiveness of an intervention which also enable comparisons across studies. METHODS: We reviewed the recent literature on randomised trials on longitudinal cancer pain to identify sources of loss of data information by collecting material on the nature of outcomes collected, analysed, the method of analysis and what was presented as a result of the trial. Illustrated with real data, we propose some guidelines on how to adequately analyse longitudinal data and report the results using mixed models. RESULTS: We identified some major source of data information loss, one of which is the transformation of a continuous pain outcome. Not adjusting for the collected outcome baseline value is moreover a source of bias. Multiple testing by analysing the data cross-sectionnally at each time-point leads to loss of information and power. Finally, effect sizes reflecting the effectiveness of the intervention were never reported. CONCLUSIONS: We identified several sources of information loss in the way longitudinal trials on pain were analysed and reported. However these problems could be easily solved by using regression methods like mixed models and presenting regression parameters to provide a concrete quantitative effect of the intervention. PMID- 27716117 TI - The experience of Greek-Cypriot individuals living with mental illness: preliminary results of a phenomenological study. AB - BACKGROUND: Research evidence shows that healthcare professionals do not fully comprehend the difficulty involved in problems faced by people living with severe mental illness (SMI). As a result, mental health service consumers do not show confidence in the healthcare system and healthcare professionals, a problem related to the phenomenon of adherence to therapy. Moreover, the issue of unmet needs in treating individuals living with SMI is relared to their quality of life in a negative way. METHODS: A qualitative methodological approach based on the methodology of van Manen phenomenology was employed through a purposive sampling of ten people living with SMI. The aim was to explore their perceptions and interpretations regarding: a) their illness, b) their self-image throughout the illness, c) the social implications following their illness, and d) the quality of the therapeutic relationship with mental health nurses. Participants were recruited from a community mental health service in a Greek-Cypriot urban city. Data were collected through personal, semi-structured interviews. RESULTS: Several main themes were identified through the narratives of all ten participants. Main themes included: a) The meaning of mental illness, b) The different phases of the illness in time, c) The perception of the self during the illness, d) Perceptions about the effectiveness of pharmacotherapy, e) Social and personal consequences for participants following the diagnosis of mental illness, f) Participants' perceptions regarding mental health professionals and services and g) The therapeutic effect of the research interview on the participants. CONCLUSIONS: The present study provides data for the enhancement of the empathic understanding of healthcare professionals regarding the concerns and particular needs of individuals living with SMI, as well as the formation of targeted psychosocial interventions based on these needs. Overall, the present data illuminate the necessity for the reconstruction of the provided mental healthcare in Cyprus into a more recovery- oriented approach in order to address personal identity and self-determination issues and the way these are related to management of pharmacotherapy. Qualitative studies aiming to further explore issues of self-identity during ill health and its association with adherence to therapy, resilience and self-determination, are also proposed.

PMID- 27716119 TI - A survey of physician receptivity to molecular diagnostic testing and readiness to act on results for early-stage colon cancer patients. AB - BACKGROUND: We sought to assess physician interest in molecular prognosic testing for patients with early stage colon cancer, and identify factors associated with the likelihood of test adoption. METHODS: We identified physicians who care for patients with early-stage (pN0) colon cancer patients, mailed them a survey, and analyzed survey responses to assess clinician receptivity to the use of a new molecular test (GUCY2C) that identifies patients at risk for recurrence, and clinician readiness to act on abnormal test results. RESULTS: Of 104 eligible potential respondents, 41 completed and returned the survey. Among responding physicians, 56 % were receptive to using the new prognostic test. Multivariable analyses showed that physicians in academic medical centers were significantly more receptive to molecular test use than those in non-academic settings. Forty one percent of respondents were ready to act on abnormal molecular test results. Physicians who viewed current staging methods as inaccurate and were confident in their capacity to incorporate molecular testing in practice were more likely to say they would act on abnormal test results. CONCLUSIONS: Physician receptivity to molecular diagnostic testing for early-stage colon cancer patients is likely to be influenced by practice setting and perceptions related to delivering quality care to patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01972737. PMID- 27716118 TI - Selective depletion of tumour suppressors Deleted in Colorectal Cancer (DCC) and neogenin by environmental and endogenous serine proteases: linking diet and cancer. AB - BACKGROUND: The related tumour suppressor proteins Deleted in Colorectal Cancer (DCC) and neogenin are absent or weakly expressed in many cancers, whereas their insertion into cells suppresses oncogenic behaviour. Serine proteases influence the initiation and progression of cancers although the mechanisms are unknown. METHODS: The effects of environmental (bacterial subtilisin) and endogenous mammalian (chymotrypsin) serine proteases were examined on protein expression in fresh, normal tissue and human neuroblastoma and mammary adenocarcinoma lines. Cell proliferation and migration assays (chemoattraction and wound closure) were used to examine cell function. Cells lacking DCC were transfected with an ectopic dcc plasmid. RESULTS: Subtilisin and chymotrypsin selectively depleted DCC and neogenin from cells at nanomolar concentrations without affecting related proteins. Cells showed reduced adherence and increased migration, but after washing they re-attached within 24 h, with recovery of protein expression. These effects are induced by chymotryptic activity as they are prevented by chymostatin and the soybean Bowman-Birk inhibitor typical of many plant protease inhibitors. CONCLUSIONS: Bacillus subtilis, which secretes subtilisin is widely present in soil, the environment and the intestinal contents, while subtilisin itself is used in meat processing, animal feed probiotics and many household cleaning agents. With chymotrypsin present in chyme, blood and tissues, these proteases may contribute to cancer development by depleting DCC and neogenin. Blocking their activity by Bowman-Birk inhibitors may explain the protective effects of a plant diet. Our findings identify a potential non-genetic contribution to cancer cell behaviour which may explain both the association of processed meats and other factors with cancer incidence and the protection afforded by plant-rich diets, with significant implications for cancer prevention. PMID- 27716122 TI - Atypical presentation of primary intraocular lymphoma. AB - BACKGROUND: In 2014, Pang et al. reported three cases with vitelliform submaculopathy as a preceding lesion of primary intraocular lymphoma (PIOL). Here, we report a case with an atypical presentation of PIOL who initially presented with vitelliform submaculopathy, vitreous haze and preripheral retinal focus. CASE PRESENTATION: A 73-year-old female initially visited another hospital with a chief complaint of acute reduced vision in the right eye. Funduscopic examination of the right eye showed a yellowish retinal lesion at the fovea with vitreous haze and retinal foci scattered in the peripheral region. Spectral domain optic coherence tomography (SD-OCT) revealed a hyperreflective subretinal debris above the retinal pigment epithelium (RPE) at the fovea, suggesting vitelliform submaculopathy. Vitrectomy was performed to improve visualization of the retinal lesions and for examination of PIOL. Vitreous cytology was class III and cytokine analysis of vitreous fluid showed increased IL-10 and an IL-10/IL-6 ratio >1, suggesting PIOL. Thereafter, there was a sub-RPE infiltration of presumed lymphoma in the nasal retina, and PCR analysis of anterior chamber fluid indicated IgH gene rearrangement, leading to diagnosis of PIOL. Three months later, there was complete disappearance of the vitelliform submacular lesion, with resultant disruption and thinning of the outer retinal layers on SD-OCT images. CONCLUSIONS: Clinicians should be aware of atypical manifestations of PIOL such as vitelliform submaculopathy and peripheral retinal foci with vitreous haze. The patient's unusual funduscopic changes are findings that have not reported in patients with PIOL. PMID- 27716123 TI - Effectiveness of bandage contact lens application in corneal epithelialization and pain alleviation following corneal transplantation; prospective, randomized clinical trial. AB - BACKGROUND: To assess the efficacy of bandage contact lens (BCL) application to promote epithelialization and alleviate pain following corneal transplantation. METHODS: Twenty-six consecutive patients who underwent corneal transplantation were randomly assigned to undergo BCL application (BCL group, n = 14) or no BCL application (control group, n = 12) at the end of the surgery. Corneal epithelialization was analyzed by photography using fluorescein staining, and ocular pain was measured using a visual analog scale. RESULTS: The mean size of the epithelial defect relative to the graft area in the BCL group was 21.80 +/- 35.10 % at the end of surgery, 18.20 +/- 31.10 % on postoperative day 1, and 5.45 +/- 11.10 % on postoperative days 3 to 5. These values in the control group were 9.64 +/- 17.60 % at the end of surgery, 11.50 +/- 25.70 % on postoperative day 1, and 0.00 +/- 0.00 % on postoperative days 3 to 5. There were no significant differences in the speed of epithelialization between the two groups. The mean preoperative pain score in the BCL group was slightly higher than that control (4.27 +/- 1.96 vs. 2.41 +/- 2.18, respectively; P = 0.039). The scores significantly increased on postoperative day 1 and promptly returned to preoperative levels by day 7 in both groups, and there were no significant differences between the groups. CONCLUSIONS: No significant benefits of BCL application at the time of corneal transplantation were observed in this study. The efficacy and safety of BCLs in eyes with compromised epithelialization require further study. TRIAL REGISTRATION NUMBER: UMIN 000019091 . Date of registration: 2015/09/22. PMID- 27716121 TI - Leucine-rich diet alters the 1H-NMR based metabolomic profile without changing the Walker-256 tumour mass in rats. AB - BACKGROUND: Cachexia is one of the most important causes of cancer-related death. Supplementation with branched-chain amino acids, particularly leucine, has been used to minimise loss of muscle tissue, although few studies have examined the effect of this type of nutritional supplementation on the metabolism of the tumour-bearing host. Therefore, the present study evaluated whether a leucine rich diet affects metabolomic derangements in serum and tumour tissues in tumour bearing Walker-256 rats (providing an experimental model of cachexia). METHODS: After 21 days feeding Wistar female rats a leucine-rich diet, distributed in L leucine and LW-leucine Walker-256 tumour-bearing groups, we examined the metabolomic profile of serum and tumour tissue samples and compared them with samples from tumour-bearing rats fed a normal protein diet (C - control; W - tumour-bearing groups). We utilised 1H-NMR as a means to study the serum and tumour metabolomic profile, tumour proliferation and tumour protein synthesis pathway. RESULTS: Among the 58 serum metabolites examined, we found that 12 were altered in the tumour-bearing group, reflecting an increase in activity of some metabolic pathways related to energy production, which diverted many nutrients toward tumour growth. Despite displaying increased tumour cell activity (i.e., higher Ki-67 and mTOR expression), there were no differences in tumour mass associated with changes in 23 metabolites (resulting from valine, leucine and isoleucine synthesis and degradation, and from the synthesis and degradation of ketone bodies) in the leucine-tumour group. This result suggests that the majority of nutrients were used for host maintenance. CONCLUSION: A leucine rich diet, largely used to prevent skeletal muscle loss, did not affect Walker 256 tumour growth and led to metabolomic alterations that may partially explain the positive effects of leucine for the whole tumour-bearing host. PMID- 27716124 TI - Safer drug use in primary care - a pilot intervention study to identify improvement needs and make agreements for change in five Swedish primary care units. AB - BACKGROUND: There is an urgent need to improve patient safety in the area of medication treatment among the elderly. The aim of this study was to explore which improvement needs and strengths, relating to medication safety, arise from a multi-professional intervention in primary care and further to describe and follow up on the agreements for change that were established within the intervention. METHODS: The SAKLAK project was a multi-professional intervention in primary care consisting of self-assessment, peer-review, feedback and written agreements for change. Data were obtained from five primary care units randomised to the intervention group. Reviewer feedback reports and agreements for change were analysed using content analysis. RESULTS: Strengths that were identified included a committed leadership, work methods to enhance medication safety and access to consultants. Methods for securing an accurate medication list, knowledge and methods of working of the prescriber and patient's ability to contribute to medication safety were areas that gave rise to three predesigned categories for improvement needs on a local level. Another category became apparent during the analysis; namely learning from mistakes and from results. In all categories, apparent shortcomings were identified. These included inaccurate medication lists, lack of medication reconciliation, lack of time for follow-up of elderly patients, need for further education in geriatrics and pharmacotherapy and lack of information on indication and maximum dosage. An increased number of medication reviews were among the most common agreements for change seen. CONCLUSIONS: This study identified substantial shortcomings, like poorly updated medication lists, which affected medication safety in the participating Swedish primary care units. Similar shortcomings are most likely present in other primary care units in the country. Working together multi-professionally, including performing medication reviews, could be one way of improving medication safety. On the other hand, the individual physician must possess enough pharmaceutical knowledge and the working conditions must allow time for follow-up of prescriptions. Strengths of the primary care unit, such as successful methods of working, must be taken advantage of. The culture in primary care may affect the ability to successfully implement routines that improve patient safety and reduce risk of medication errors. PMID- 27716126 TI - Unraveling the molecular basis of oxidative stress management in a drought tolerant rice genotype Nagina 22. AB - BACKGROUND: Drought stress tolerance for crop improvement is an important goal worldwide. Drought is a complex trait, and it is vital to understand the complex physiological, biochemical, and molecular mechanisms of drought tolerance to tackle it effectively. Osmotic adjustment, oxidative stress management (OSM), and cell membrane stability (CMS) are major components of cellular tolerance under drought stress. In the current study, we explored the molecular basis of OSM in the drought tolerant rice variety, Nagina 22 and compared it with the popular drought sensitive rice variety, IR 64, under drought imposed at the reproductive stage, to understand how the parental polymorphisms correlate with the superiority of Nagina 22 and tolerant bulk populations under drought. RESULTS: We generated recombinant inbred lines (RIL) from contrasting parents Nagina 22 and IR 64 and focussed on spikelet fertility (SF), in terms of its correlation with OSM, which is an important component of drought tolerance in Nagina 22. Based on SF under drought stress and its correlations with other yield related traits, we used superoxide dismutase (SOD), glutathione reductase (GR), and ascorbate peroxidase (APX) activity assays to establish the relationship between SF and OSM genes in the tolerant and sensitive lines. Among the OSM enzymes studied, GR had a significant and positive correlation with single plant yield (SPY) under drought stress. GR was also positively correlated with APX but negatively so with SOD. Interestingly, none of the enzyme-morphology correlations were significant under irrigated control (IC). Through genome-wide SNP analysis of the 21 genes encoding for OSM enzymes, we identified the functional polymorphisms between the parents and identified superior alleles. By using network analysis of OSM genes in rice, we identified the genes that are central to the OSM network. CONCLUSIONS: From the biochemical and morphological data and the SNP analysis, the superiority of Nagina 22 in spikelet fertility under drought stress is because of its superior alleles for SOD (SOD2, SODCC1, SODA) and GR (GRCP2) rather than for APX, for which IR 64 had the superior allele (APX8). Nagina 22 can bypass APX8 by directly interacting with SODA. For nine of the 11 genes present in the central network, Nagina 22 had the superior alleles. We propose that Nagina 22 tolerance could mainly be because of SODA which is a reactive oxygen scavenger in mitochondria which is directly associated with spikelet fertility. PMID- 27716127 TI - Level of nutrition knowledge and its association with fat consumption among college students. AB - BACKGROUND: Intake of saturated fat, trans fat, and cholesterol has been associated with increased risk of coronary heart disease. The aim of this study was to explore whether increased nutrition knowledge is associated with a reduction in the consumption of unhealthy fats in a sample of university students. METHODS: A sample of 231 students, with a mean age of 20 years, was recruited from university campus during spring 2012. Students completed a validated questionnaire related to students' demographic, nutrition knowledge, and daily fat consumption. Weight, height, and waist circumference were measured. Data were analyzed using one-way ANOVA, chi-square, and student's t-test. RESULTS: Results indicate that female students have greater nutrition knowledge than male students (the mean nutrition score for women was 5 points higher than that of men (P = 0.01)). Nutrition knowledge was negatively correlated with fat and cholesterol intake. Students who consumed more than 35 % calories from fat or >300 mg of cholesterol daily had lower mean nutrition scores than those students with lower fat or cholesterol intake (8 points lower and 7.9 points lower, respectively). Using linear regression for nutrition scores on estimated saturated fat intake and cholesterol intake (controlling for gender, height, weight, age, and dieting), nutrition scores were negatively associated with saturated fat intake (-0.15, P <0.0001) and cholesterol intake (-1.38, P <0.0001). CONCLUSION: Students with greater nutritional knowledge consumed less unhealthy fats and cholesterol. This finding magnifies the role of nutrition education as a potential tool in health campaigns to promote healthy eating patterns among college students. Results of this pilot study can inform the design of future nutrition education intervention studies to assess the efficacy of nutrition knowledge on pattern of fat consumption among college students. PMID- 27716125 TI - DARS: a phase III randomised multicentre study of dysphagia- optimised intensity- modulated radiotherapy (Do-IMRT) versus standard intensity- modulated radiotherapy (S-IMRT) in head and neck cancer. AB - BACKGROUND: Persistent dysphagia following primary chemoradiation (CRT) for head and neck cancers can have a devastating impact on patients' quality of life. Single arm studies have shown that the dosimetric sparing of critical swallowing structures such as the pharyngeal constrictor muscle and supraglottic larynx can translate to better functional outcomes. However, there are no current randomised studies to confirm the benefits of such swallow sparing strategies. The aim of Dysphagia/Aspiration at risk structures (DARS) trial is to determine whether reducing the dose to the pharyngeal constrictors with dysphagia-optimised intensity- modulated radiotherapy (Do-IMRT) will lead to an improvement in long- term swallowing function without having any detrimental impact on disease specific survival outcomes. METHODS/DESIGN: The DARS trial (CRUK/14/014) is a phase III multicentre randomised controlled trial (RCT) for patients undergoing primary (chemo) radiotherapy for T1-4, N0-3, M0 pharyngeal cancers. Patients will be randomised (1:1 ratio) to either standard IMRT (S-IMRT) or Do-IMRT. Radiotherapy doses will be the same in both groups; however in patients allocated to Do-IMRT, irradiation of the pharyngeal musculature will be reduced by delivering IMRT identifying the pharyngeal muscles as organs at risk. The primary endpoint of the trial is the difference in the mean MD Anderson Dysphagia Inventory (MDADI) composite score, a patient-reported outcome, measured at 12 months post radiotherapy. Secondary endpoints include prospective and longitudinal evaluation of swallow outcomes incorporating a range of subjective and objective assessments, quality of life measures, loco-regional control and overall survival. Patients and speech and language therapists (SLTs) will both be blinded to treatment allocation arm to minimise outcome-reporting bias. DISCUSSION: DARS is the first RCT investigating the effect of swallow sparing strategies on improving long-term swallowing outcomes in pharyngeal cancers. An integral part of the study is the multidimensional approach to swallowing assessment, providing robust data for the standardisation of future swallow outcome measures. A translational sub- study, which may lead to the development of future predictive and prognostic biomarkers, is also planned. TRIAL REGISTRATION: This study is registered with the International Standard Randomised Controlled Trial register, ISRCTN25458988 (04/01/2016). PMID- 27716128 TI - Is tailored treatment superior to non-tailored treatment for pain and disability in women with non-specific neck pain? A randomized controlled trial. AB - BACKGROUND: The evidence for the effect of treatments of neck pain is modest. In the absence of causal treatments, a possibility is to tailor the treatment to the individuals' functional limitations and symptoms. The aim was to evaluate treatment effects of a tailored treatment versus a non-tailored treatment. Our hypothesis was that tailored treatment (TT) would have better effect on pain intensity and disability than either non-tailored treatment (NTT) (same treatment components but applied quasi-randomly) or treatment-as-usual (TAU) (no treatment from the study, no restrictions). We further hypothesized that TT and NTT would both have better effect than TAU. METHOD: One hundred twenty working women with subacute and chronic non-specific neck pain were allocated to 11 weeks of either TT, NTT or TAU in a randomized controlled trial with follow-ups at 3, 9 and 15 months. The TT was designed from a decision model based on assessment of function and symptoms with defined cut-off levels for the following categories: reduced cervical mobility, impaired neck-shoulder strength and motor control, impaired eye-head-neck control, trapezius myalgia and cervicogenic headache. Primary outcomes were pain and disability. Secondary outcomes were symptoms, general improvement, work productivity, and pressure pain threshold of m. trapezius. RESULTS: Linear mixed models analysis showed no differences between TT and NTT besides work productivity favoring TT at 9- and 15-months follow-ups. TT and NTT improved significantly more than TAU on pain, disability and symptoms at 3-month follow-up. General improvement also favored TT and NTT over TAU at all follow ups. CONCLUSION: Tailored treatment according to our proposed decision model was not more effective than non-tailored treatment in women with subacute and chronic neck pain. Both tailored and non-tailored treatments had better short-term effects than treatment-as-usual, supporting active and specific exercise therapy, although therapist-patient interaction was not controlled for. Better understanding of the importance of functional impairments for pain and disability, in combination with a more precise tailoring of specific treatment components, is needed to progress.

PMID- 27716129 TI - Predictors of homelessness among vulnerably housed adults in 3 Canadian cities: a prospective cohort study. AB - BACKGROUND: Homelessness is a major concern in many urban communities across North America. Since vulnerably housed individuals are at risk of experiencing homelessness, it is important to identify predictive factors linked to subsequent homelessness in this population. The objectives of this study were to determine the probability of experiencing homelessness among vulnerably housed adults over three years and factors associated with higher risk of homelessness. METHODS: Vulnerably housed adults were recruited in three Canadian cities. Data on demographic characteristics, chronic health conditions, and drug use problems were collected through structured interviews. Housing history was obtained at baseline and annual follow-up interviews. Generalized estimating equations were used to characterize associations between candidate predictors and subsequent experiences of homelessness during each follow-up year. RESULTS: Among 561 participants, the prevalence of homelessness was 29.2 % over three years. Male gender (AOR = 1.59, 95 % CI: 1.14-2.21) and severe drug use problems (AOR = 1.98, 95 % CI: 1.22-3.20) were independently associated with experiencing homelessness during the follow-up period. Having >=3 chronic conditions (AOR = 0.55, 95 % CI: 0.33-0.94) and reporting higher housing quality (AOR = 0.99, 95 % CI: 0.97-1.00) were protective against homelessness. CONCLUSIONS: Vulnerably housed individuals are at high risk for experiencing homelessness. The study has public health implications, highlighting the need for enhanced access to addiction treatment and improved housing quality for this population. PMID- 27716130 TI - Novel microRNA discovery using small RNA sequencing in post-mortem human brain. AB - BACKGROUND: MicroRNAs (miRNAs) are short, non-coding RNAs that regulate gene expression mainly through translational repression of target mRNA molecules. More than 2700 human miRNAs have been identified and some are known to be associated with disease phenotypes and to display tissue-specific patterns of expression. METHODS: We used high-throughput small RNA sequencing to discover novel miRNAs in 93 human post-mortem prefrontal cortex samples from individuals with Huntington's disease (n = 28) or Parkinson's disease (n = 29) and controls without neurological impairment (n = 36). A custom miRNA identification analysis pipeline was built, which utilizes miRDeep* miRNA identification and result filtering based on false positive rate estimates. RESULTS: Ninety-nine novel miRNA candidates with a false positive rate of less than 5 % were identified. Thirty four of the candidate miRNAs show sequence similarity with known mature miRNA sequences and may be novel members of known miRNA families, while the remaining 65 may constitute previously undiscovered families of miRNAs. Nineteen of the 99 candidate miRNAs were replicated using independent, publicly-available human brain RNA-sequencing samples, and seven were experimentally validated using qPCR. CONCLUSIONS: We have used small RNA sequencing to identify 99 putative novel miRNAs that are present in human brain samples. PMID- 27716132 TI - The effect of financial incentives on top of behavioral support on quit rates in tobacco smoking employees: study protocol of a cluster-randomized trial. AB - BACKGROUND: Stimulating successful tobacco cessation among employees has multiple benefits. Employees who quit tobacco are healthier, more productive, less absent from work, and longer employable than employees who continue to use tobacco. Despite the evidence for these benefits of tobacco cessation, a successful method to stimulate employees to quit tobacco is lacking. The aim of this study is to evaluate whether adding a financial incentive to behavioral support (compared with no additional incentive) is effective and cost-effective in increasing abstinence rates in tobacco smoking employees participating in a smoking cessation group training. METHODS/DESIGN: In this cluster-randomized trial employees in the intervention and control group both participate in a smoking cessation group training consisting of seven weekly counseling sessions of ninety minutes each. In addition to the training, employees in the intervention group receive a voucher as an incentive for being abstinent from smoking at the end of the training (?50), after three months (?50), after six months (?50), and after one year (?200). The control group does not receive any incentive. The primary outcome is carbon monoxide validated 12-month continuous abstinence from smoking (Russel's standard). Additionally, an economic evaluation is performed from a societal and an employer perspective. DISCUSSION: The present paper describes the methods and design of this cluster-randomized trial in detail. We hypothesize that the financial incentive for abstinence in the form of vouchers increases abstinence rates over and above the group training. The results of this study can provide important recommendations for enhancement of employee tobacco cessation. TRIAL REGISTRATION: Dutch Trial Register: NTR5657 . First received 27-01-2016. PMID- 27716131 TI - Rationale and Design of the CREDENCE Trial: computed TomogRaphic evaluation of atherosclerotic DEtermiNants of myocardial IsChEmia. AB - BACKGROUND: Coronary computed tomography angiography (CCTA) allows for non invasive assessment of obstructive coronary artery disease (CAD) beyond measures of stenosis severity alone. This assessment includes atherosclerotic plaque characteristics (APCs) and calculation of fractional flow reserve (FFR) from CCTA (FFRCT). Similarly, stress imaging by myocardial perfusion scintigraphy (MPS) provides vital information. To date, the diagnostic performance of integrated CCTA assessment versus integrated MPS assessment for diagnosis of vessel-specific ischemia remains underexplored. METHODS: CREDENCE will enroll adult individuals with symptoms suspicious of CAD referred for non-emergent invasive coronary angiography (ICA), but without known CAD. All participants will undergo CCTA, MPS, ICA and FFR. FFR will be performed for lesions identified at the time of ICA to be >=40 and <90 % stenosis, or those clinically indicated for evaluation. Study analyses will focus on diagnostic performance of CCTA versus MPS against invasive FFR reference standard. An integrated stenosis-APC-FFRCT metric by CCTA for vessel-specific ischemia will be developed from derivation cohort and tested against a validation cohort. Similarly, integrated metric by MPS for vessel specific ischemia will be developed, validated and compared. An FFR value of <=0.80 will be considered as ischemia causing. The primary endpoint will be the diagnostic accuracy of vessel territory-specific ischemia of integrated stenosis APC-FFRCT measure by CCTA, compared with perfusion or perfusion-myocardial blood flow stress imaging testing, against invasive FFR. DISCUSSION: CREDENCE will determine the performance of integrated CCTA metric compared to integrated MPS measure for diagnosis of vessel-specific ischemia. If proven successful, this study may reduce the number of missed diagnoses and help to optimally predict ischemia-causing lesions. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02173275 .

PMID- 27716133 TI - Diet quality is associated with obesity and hypertension in Australian adults: a cross sectional study. AB - BACKGROUND: Poor diet, characterized by a low diet quality score, has been associated with greater prevelence of obesity and hypertension. However, the evidence is inconsistent across diet quality scores and by sex. The aim was to investigate the relationship between diet quality and obesity and hypertension. METHODS: Adults (n = 4908; age 45.2 +/- 0.24 years) were included from the cross sectional Australian Health Survey 2011-2013. Two 24-h dietary recalls were used to derive the dietary guideline index (DGI) and recommended food score (RFS). Logistic regression investigated relationships between diet quality score and odds ratio of obesity, hypertension and obesity-associated hypertension. RESULTS: In the highest tertile of DGI, but not RFS, individuals were less likely to be obese (men: OR 0.64, CI: 0.45, 0.92, P-trend = 0.014; women: 0.68, 0.48, 0.96, P trend = 0.025) and to have central adiposity (men: 0.68, 0.48, 0.97, P-trend = 0.030; women: 0.53, 0.37, 0.77, P-trend = 0.001) compared with the lowest tertile. Men, but not women, in the highest tertile of DGI and RFS were less likely to be hypertensive (DGI: 0.56, 0.37, 0.85, P-trend = 0.006; RFS: 0.62, 0.41, 0.94, P-trend = 0.021) compared with the lowest tertile. In men with obesity, but not normal weight men or women, those in the highest tertile of DGI were less likely to be hypertensive (0.53, 0.36, 0.78, P-trend = 0.001) compared with the highest tertile. CONCLUSIONS: Higher diet quality, as estimated using DGI, was associated with lower odds ratio of obesity in men and women. Odds ratio of hypertension was lower in men, but not women, with a high diet quality score compared with a low score, while obesity-associated hypertension was only associated with diet quality score in men with obesity. Longitudinal studies are needed to evaluate whether diet quality predicts risk of obesity and hypertension. PMID- 27716135 TI - Remaining missed opportunities of child survival in Peru: modelling mortality impact of universal and equitable coverage of proven interventions. AB - BACKGROUND: Peru has made great improvements in reducing stunting and child mortality in the past decade, and has reached the Millennium Development Goals 1 and 4. The remaining challenges or missed opportunities for child survival needs to be identified and quantified, in order to guide the next steps to further improve child survival in Peru. METHODS: We used the Lives Saved Tool (LiST) to project the mortality impact of proven interventions reaching every women and child in need, and the mortality impact of eliminating inequalities in coverage distribution between wealth quintiles and urban-rural residence. RESULTS: Our analyses quantified the remaining missed opportunities in Peru, where prioritizing scale-up of facility-based case management for all small and sick babies will be most effective in mortality reduction, compared to other evidenced based interventions that prevent maternal and child deaths. Eliminating coverage disparities between the poorest quintiles and the richest will reduce under-five and neonatal mortality by 22.0 and 40.6 %, while eliminating coverage disparities between those living in rural and urban areas will reduce under-five and neonatal mortality by 29.3 and 45.2 %. This projected neonatal mortality reduction achieved by eliminating coverage disparities is almost comparable to that already achieved by Peru over the past decade. CONCLUSIONS: Although Peru has made great strides in improving child survival, further improvement in child health, especially in newborn health can be achieved if there is universal and equitable coverage of proven, quality health facility-based interventions. The magnitude of reduction in mortality will be similar to what has been achieved in the past decade. Strengthening health system to identify, understand, and direct resources to the poor and rural areas will ensure that Peru achieve the Sustainable Development Goals by 2030. PMID- 27716136 TI - Linking Swedish health data registers to establish a research database and a shared decision-making tool in hip replacement. AB - BACKGROUND: Sweden offers a unique opportunity to researchers to construct comprehensive databases that encompass a wide variety of healthcare related data. Statistics Sweden and the National Board of Health and Welfare collect individual level data for all Swedish residents that ranges from medical diagnoses to socioeconomic information. In addition to the information collected by governmental agencies the medical profession has initiated nationwide Quality Registers that collect data on specific diagnoses and interventions. The Quality Registers analyze activity within healthcare institutions, with the aims of improving clinical care and fostering clinical research. MAIN BODY: The Swedish Hip Arthroplasty Register (SHAR) has been collecting data since 1979. Joint replacement in general and hip replacement in particular is considered a success story with low mortality and complication rate. It is credited to the pioneering work of the SHAR that the revision rate following hip replacement surgery in Sweden is amongst the lowest in the world. This has been accomplished by the diligent follow-up of patients with feedback of outcomes to the providers of the healthcare along with post market surveillance of individual implant performance. During its existence SHAR has experienced a constant organic growth. One major development was the introduction of the Patient Reported Outcome Measures program, giving a voice to the patients in healthcare performance evaluation. The next aim for SHAR is to integrate patients' wishes and expectations with the surgeons' expertise in the form of a Shared Decision-Making (SDM) instrument. The first step in building such an instrument is to assemble the necessary data. This involves linking the SHARs database with the two aforementioned governmental agencies. The linkage is done by the 10-digit personal identity number assigned at birth (or immigration) for every Swedish resident. The anonymized data is stored on encrypted serves and can only be accessed after double identification. CONCLUSION: This data will serve as starting point for several research projects and clinical improvement work.

PMID- 27716138 TI - Comparing the mortality risks of nursing professionals with diabetes and general patients with diabetes: a nationwide matched cohort study. AB - BACKGROUND: Nursing professionals have received comprehensive medical education and training. However, whether these medical professionals exhibit positive patient care attitudes and behaviors and thus reduce mortality risks when they themselves are diagnosed with chronic diseases is worth exploring. This study compared the mortality risks of female nurses and general patients with diabetes and elucidated factors that caused this difference. METHODS: A total of 510,058 female patients newly diagnosed with diabetes between 1998 and 2006 as recorded in the National Health Insurance Research Database were the participants in this study. Nurses with diabetes and general population with diabetes were matched with propensity score method in a 1:10 ratio. The participants were tracked from the date of diagnosis to 2009. The Cox proportional hazards model was utilized to compare the mortality risks in the two groups. RESULTS: Nurses were newly diagnosed with diabetes at a younger age compared with the general public (42.01 +/- 12.03 y vs. 59.29 +/- 13.11 y). Nevertheless, the matching results showed that nurses had lower mortality risks (HR: 0.53, 95 % CI: 0.38-0.74) and nurses with diabetes in the < 35 and 35-44 age groups exhibited significantly lower mortality risks compared with general patients (HR: 0.23 and 0.36). A further analysis indicated that the factors that influenced the mortality risks of nurses with diabetes included age, catastrophic illnesses, and the severity of diabetes complications. CONCLUSION: Nurses with diabetes exhibited lower mortality risks possibly because they had received comprehensive medical education and training, may had more knowledge regarding chronic disease control and change their lifestyles. The results can serve as a reference for developing heath education, and for preventing occupational hazards in nurses. PMID- 27716139 TI - Comparison of pharmaceutical, illicit drug, alcohol, nicotine and caffeine levels in wastewater with sale, seizure and consumption data for 8 European cities. AB - BACKGROUND: Monitoring the scale of pharmaceuticals, illicit and licit drugs consumption is important to assess the needs of law enforcement and public health, and provides more information about the different trends within different countries. Community drug use patterns are usually described by national surveys, sales and seizure data. Wastewater-based epidemiology (WBE) has been shown to be a reliable approach complementing such surveys. METHOD: This study aims to compare and correlate the consumption estimates of pharmaceuticals, illicit drugs, alcohol, nicotine and caffeine from wastewater analysis and other sources of information. Wastewater samples were collected in 2015 from 8 different European cities over a one week period, representing a population of approximately 5 million people. Published pharmaceutical sale, illicit drug seizure and alcohol, tobacco and caffeine use data were used for the comparison. RESULTS: High agreement was found between wastewater and other data sources for pharmaceuticals and cocaine, whereas amphetamines, alcohol and caffeine showed a moderate correlation. methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA) and nicotine did not correlate with other sources of data. Most of the poor correlations were explained as part of the uncertainties related with the use estimates and were improved with other complementary sources of data. CONCLUSIONS: This work confirms the promising future of WBE as a complementary approach to obtain a more accurate picture of substance use situation within different communities. Our findings suggest further improvements to reduce the uncertainties associated with both sources of information in order to make the data more comparable. PMID- 27716140 TI - Longitudinal survey of Clostridium difficile presence and gut microbiota composition in a Belgian nursing home. AB - BACKGROUND: Increasing age, several co-morbidities, environmental contamination, antibiotic exposure and other intestinal perturbations appear to be the greatest risk factors for C. difficile infection (CDI). Therefore, elderly care home residents are considered particularly vulnerable to the infection. The main objective of this study was to evaluate and follow the prevalence of C. difficile in 23 elderly care home residents weekly during a 4-month period. A C. difficile microbiological detection scheme was performed along with an overall microbial biodiversity study of the faeces content by 16S rRNA gene analysis. RESULTS: Seven out of 23 (30.4 %) residents were (at least one week) positive for C. difficile. C. difficile was detected in 14 out of 30 diarrhoeal samples (43.7 %). The most common PCR-ribotype identified was 027. MLVA showed that there was a clonal dissemination of C. difficile strains within the nursing home residents. 16S-profiling analyses revealed that each resident has his own bacterial imprint, which was stable during the entire study. Significant changes were observed in C. difficile positive individuals in the relative abundance of a few bacterial populations, including Lachnospiraceae and Verrucomicrobiaceae. A decrease of Akkermansia in positive subjects to the bacterium was repeatedly found. CONCLUSIONS: A high C. difficile colonisation in nursing home residents was found, with a predominance of the hypervirulent PCR-ribotype 027. Positive C. difficile status is not associated with microbiota richness or biodiversity reduction in this study. The link between Akkermansia, gut inflammation and C. difficile colonisation merits further investigations. PMID- 27716141 TI - Multi-omics analysis reveals regulators of the response to PDGF-BB treatment in pulmonary artery smooth muscle cells. AB - BACKGROUND: Pulmonary arterial hypertension (PAH) is a lethal disease with pronounced narrowing of pulmonary vessels due to abnormal cell proliferation. The platelet-derived growth factor BB (PDGF-BB) is well known as a potent mitogen for smooth muscle cell proliferation. To better understand how this growth factor regulates pulmonary arterial smooth muscle cells (PASMCs) proliferation, we sought to characterize the response to PDGF-BB stimulation at system-wide levels, including the transcriptome and proteome. RESULTS: In this study, we identified 1611 mRNAs (transcriptome), 207 proteins (proteome) differentially expressed in response to PDGF-BB stimulation in PASMCs based on RNA-sequencing and isobaric tags for relative and absolute quantification (iTRAQ) assay. Transcription factor (TF)-target network analysis revealed that PDGF-BB regulated gene expression potentially via TFs including HIF1A, JUN, EST1, ETS1, SMAD1, FOS, SP1, STAT1, LEF1 and CEBPB. Among them, SMAD1-involved BMPR2/SMADs axis plays a significant role in PAH development. Interestingly, we observed that the expression of BMPR2 was decreased in both mRNA and protein level in response to PDGF-BB. Further study revealed that BMPR2 is the direct target of miR-376b that is up-regulated upon PDGF-BB treatment. Finally, EdU incorporation assay showed that miR-376b promoted proliferation of PASMCs. CONCLUSION: This integrated analysis of PDGF-BB regulated transcriptome and proteome was performed for the first time in normal PASMCs, which revealed a crosstalk between PDGF signaling and BMPR2/SMADs axis. Further study demonstrated that PDGF-BB-induced miR-376b upregulation mediated the downregulation of BMPR2, which led to expression change of its downstream targets and promoted proliferation of PASMCs. PMID- 27716142 TI - Successful customer intercept interview recruitment outside small and midsize urban food retailers. AB - BACKGROUND: Customer intercept interviews are increasingly used to characterize food purchases at retail food outlets and restaurants; however, methodological procedures, logistical issues and response rates using intercept methods are not well described in the food environment literature. The aims of this manuscript were to 1) describe the development and implementation of a customer intercept interview protocol in a large, NIH-funded study assessing food purchases in small and midsize food retailers in Minneapolis and St. Paul, Minnesota, 2) describe intercept interview response rates by store type and environmental factors (e.g., neighborhood socioeconomic status, day/time, weather), and 3) compare demographic characteristics (e.g., gender, race/ethnicity) of participants versus non participants. METHODS: After a pilot phase involving 28 stores, a total of 616 interviews were collected from customers exiting 128 stores in fall 2014. The number of eligible customers encountered per hour (a measure of store traffic), participants successfully recruited per hour, and response rates were calculated overall and by store type, neighborhood socio-economic status, day and time of data collection, and weather. Response rates by store type, neighborhood socio economic status, time and day of data collection, and weather, and characteristics of participants and non-participants were compared using chi square tests. RESULTS: The overall response rate was 35 %, with significantly higher response rates at corner/small grocery stores (47 %) and dollar stores (46 %) compared to food-gas marts (32 %) and pharmacies (26 %), and for data collection between 4:00-6:00 pm on weekdays (40 %) compared to weekends (32 %). The distribution of race/ethnicity, but not gender, differed between participants and non-participants (p < 0.01), with greater participation rates among those identified as Black versus White. CONCLUSIONS: Customer intercept interviews can be successfully used to recruit diverse samples of customers at small and midsize food retailers. Future community-based studies using customer intercept interviews should collect data sufficient to report response rates and consider potential differences between the racial/ethnic composition of the recruited sample and the target population. PMID- 27716143 TI - Reduced representation bisulphite sequencing of ten bovine somatic tissues reveals DNA methylation patterns and their impacts on gene expression. AB - BACKGROUND: As a major epigenetic component, DNA methylation plays important functions in individual development and various diseases. DNA methylation has been well studied in human and model organisms, but only limited data exist in economically important animals like cattle. RESULTS: Using reduced representation bisulphite sequencing (RRBS), we obtained single-base-resolution maps of bovine DNA methylation from ten somatic tissues. In total, we evaluated 1,868,049 cytosines in CG-enriched regions. While we found slightly low methylation levels (29.87 to 38.06 %) in cattle, the methylation contexts (CGs and non-CGs) of cattle showed similar methylation patterns to other species. Non-CG methylation was detected but methylation levels in somatic tissues were significantly lower than in pluripotent cells. To study the potential function of the methylation, we detected 10,794 differentially methylated cytosines (DMCs) and 836 differentially methylated CG islands (DMIs). Further analyses in the same tissues revealed many DMCs (including non-CGs) and DMIs, which were highly correlated with the expression of genes involved in tissue development. CONCLUSIONS: In summary, our study provides a baseline dataset and essential information for DNA methylation profiles of cattle. PMID- 27716144 TI - Prevalence of osteoporosis in China: a meta-analysis and systematic review. AB - BACKGROUND: We conducted a systematic review and meta-analysis to obtain a reliable estimation of the prevalence of osteoporosis in China and to characterize its epidemiology. METHODS: We identified relevant studies via a search of literature published from 2003 to October 2015 in the PubMed, Web of Science, China National Knowledge Infrastructure, Wanfang and Weipu databases. Both Chinese and WHO criteria were considered acceptable for the diagnosis of osteoporosis. Prevalence estimates were obtained using random effects models. Meta-regression analysis was used to explore the sources of heterogeneity, and publication bias was evaluated by visually inspecting funnel plots. RESULTS: Overall, 69 articles were included in this study. An obvious increase in the prevalence of osteoporosis was identified over the past 12 years (prevalence of 14.94 % before 2008 and 27.96 % during the period spanning 2012-2015). The prevalence of osteoporosis was higher in females than in males (25.41 % vs. 15.33 %) and increased with age. Osteoporosis prevalence was higher in rural than in urban areas (20.87 % vs. 23.92 %) and higher in southern than in northern areas (23.17 % vs. 20.13 %). At present, the pooled prevalence of osteoporosis in people aged 50 years and older was more than twice the pooled prevalence identified in 2006 (34.65 % vs. 15.7 %). The application of different diagnostic criteria could have an impact on prevalence estimation (19.7 % vs. 29.3 %). Meta regression suggested that study setting also influenced the estimation of point prevalence (P = 0.022). CONCLUSIONS: The prevalence of osteoporosis in China has increased over the past 12 years, affecting more than one-third of people aged 50 years and older. The prevalence of osteoporosis increased with age and was higher in females than in males. Prevention and control measures have become all the more important given the increase in osteoporosis prevalence, and three-step prevention programmes should be implemented. PMID- 27716146 TI - The effect of war on infant mortality in the Democratic Republic of Congo. AB - BACKGROUND: The Democratic Republic of Congo (DRC) has suffered from war and lingering conflicts in East DRC and has one of the highest infant mortality rates in the world. Prior research has documented increases in infant and child mortality associated with war, but the empirical evidence is limited in several respects. Measures of conflict are quite crude or conflict is not tightly linked to periods of exposure to infant death. Few studies have distinguished between the effects of war on neonatal versus post-neonatal infants. No study has considered possible differences between women who give birth during wartime and those who do not that may be related to greater infant mortality. METHODS: The analysis used the nationally representative sample of 15,103 mothers and 53,768 children from the 2007 and 2013/2014 Demographic Health Survey in the DRC and indicators of conflict events and conflict deaths from the 2013 Uppsala Conflict Data. To account for unobserved heterogeneity across women, a multi-level modeling approach was followed by grouping all births for each woman and estimating random intercepts in discrete time event history models. RESULTS: Post neonatal mortality increased during the Congolese wars, and was highest where conflict events and deaths were extreme. Neonatal mortality was not associated with conflict levels. Infant mortality was not higher in East DRC, where conflicts continued during the post Congolese war period. Models specifying unobserved differences between mothers who give birth during war and those who have children in peacetime did not reduce the estimated effect of war, i.e., no support was found for selectivity in the sample of births during war. CONCLUSION: Differences in effects of the Congolese war on neonatal versus post-neonatal mortality suggest that conflict influences the conditions of infants' lives more than the aspects of mothers' pregnancy conditions and delivery that are relevant for infant mortality. These differences may, however, be specific to the nature of conflict and prior conditions in the DRC. Because of continued political instability, violent conflict may be expected to continue in contexts such as the DRC; we must therefore continue to document, analyze and monitor the mechanisms through which war influences infant mortality. PMID- 27716145 TI - Kidney function is associated with severity of white matter hyperintensity in patients with acute ischemic stroke/TIA. AB - BACKGROUND: Previous studies suggested the potential interactions between cerebrovascular diseases and impaired renal function. However, the relationship between renal function and white matter hyperintensity (WMH), marker of cerebral small vessel disease, in patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA) remains unknown. METHODS: We consecutively enrolled 1632 subjects with AIS or TIA who underwent brain MRI for this analysis. The severity of WMH in both of periventricular (PVH) and deep subcortical white matter (SDWMH) was evaluated using Fazekas scale. Estimated glomerular filtration rate (eGFR) was calculated by the equation of the Modification Diet for Renal Disease. Multinomial logistic regression was performed to evaluate the association between the severity of WMH and eGFR. RESULTS: Advanced age and hypertension were independently associated with the severity of both PVH and SDWMH (all p < 0.001). There is a significantly inverse association between eGFR and PVH. Patients having each 30 ml/min/1.73 m2 increase in eGFR was associated with 75 % of risk of having degree 3 of WMH in periventricular areas compared with degree 0 (p = 0.04, OR = 0.75, 95 % CI 0.61-0.92). However this inverse association was not found between eGFR and SDWMH (P = 0.50, OR = 0.93, 95 % CI0.75-1.14). CONCLUSION: Our study demonstrates that renal dysfunction (eGFR) is independently associated with the severity of PVH but not SDWMH in patients with acute ischemic stroke. This results highlighted different pathological mechanism and risk factors of PVH and SDWMH. PMID- 27716147 TI - Two colliding epidemics - obesity is independently associated with chronic pain interfering with activities of daily living in adults 18 years and over; a cross sectional, population-based study. AB - BACKGROUND: Chronic pain interfering with activities of daily living is highly prevalent in the community. More than 600 million people worldwide are obese. The aim of this paper is to assess if such chronic pain is associated independently with obesity across the adult population, having controlled for other key factors. METHODS: The South Australian Health Omnibus is an annual, population based, cross-sectional study. Data on 2616 participants were analysed for episodes of daily pain for three of the preceding six months. Obesity was derived from self-reported height and weight. Multivariable logistic regression analysed the associations between chronic pain interfering with activities of daily living, body mass index (BMI) and key socio-demographic factors. RESULTS: Chronic pain interfering with activities of daily living peaks in people >=75 years of age while obesity peaks in the 45-54 age group. Pain and obesity together peak in the 55-74 year age group. In the adjusted multinominal logistic regression model, compared to those with no pain, there was a strong association between obesity and pain that interfered moderately or extremely with day-to-day activities (OR 2.25; 95 % CI 1.57-3.23; p < 0.001) having controlled for respondents' age, gender, rurality, country of birth and highest educational attainment. People over 65 years of age and those with lower educational levels were more likely to experience such chronic pain related to obesity. CONCLUSION: This study demonstrates a strong association between chronic pain and obesity/morbid obesity in the South Australian population. Prospective, longitudinal data are needed to understand the dynamic interaction between these two prevalent conditions. PMID- 27716148 TI - Cirrhosis related functionality characteristic of the fecal microbiota as revealed by a metaproteomic approach. AB - BACKGROUND: Intestinal microbiota operated as a whole and was closely related with human health. Previous studies had suggested close relationship between liver cirrhosis (LC) and gut microbiota. METHODS: To determine the functional characteristic of the intestinal microbiota specific for liver cirrhosis, the fecal metaproteome of three LC patients with Child-Turcotte-Pugh (CTP) score of A, B, and C, and their spouse were first compared using high-throughput approach based on denaturing polyacrylamide gel electrophoresis and liquid chromatography tandem mass spectrometry in our study. RESULTS: A total of 5,020 proteins (88 % from bacteria, 12 % form human) were identified and annotated based on the GO and KEGG classification. Our results indicated that the LC patients possessed a core metaproteome including 119 proteins, among which 14 proteins were enhanced expressed and 7 proteins were unique for LC patients compared with the normal, which were dominant at the function of carbohydrate metabolism. In addition, LC patients have unique biosynthesis of branched chain amino acid (BCAA), pantothenate, and CoA, enhanced as CTP scores increased. Those three substances were all important in a wide array of key and essential biological roles of life. CONCLUSIONS: We observed a highly comparable cirrhosis-specific metaproteome clustering of fecal microbiota and provided the first supportive evidence for the presence of a LC-related substantial functional core mainly involved in carbohydrate, BCAA, pantothenate, and CoA metabolism, suggesting the compensation of intestinal microbiota for the fragile and innutritious body of cirrhotic patients. PMID- 27716149 TI - The effects of AST-120 on chronic kidney disease progression in the United States of America: a post hoc subgroup analysis of randomized controlled trials. AB - BACKGROUND: The orally administered spherical carbon adsorbent AST-120 is used on label in Asian countries to slow renal disease progression in patients with progressive chronic kidney disease (CKD). Recently, two multinational, randomized, double-blind, placebo-controlled, phase 3 trials (Evaluating Prevention of Progression in Chronic Kidney Disease [EPPIC] trials) examined AST 120's efficacy in slowing CKD progression. This study assessed the efficacy of AST-120 in the subgroup of patients from the United States of America (USA) in the EPPIC trials. METHODS: In the EPPIC trials, 2035 patients with moderate to severe CKD were studied, of which 583 were from the USA. The patients were randomly assigned to two groups of equal size that were treated with AST-120 or placebo (9 g/day). The primary end point was a composite of dialysis initiation, kidney transplantation, or serum creatinine doubling. RESULTS: The Kaplan-Meier curve for the time to achieve the primary end point in the placebo-treated patients from the USA was similar to that projected before the study. The per protocol subgroup analysis of the population from the USA which included patients with compliance rates of >=67 % revealed a significant difference between the treatment groups in the time to achieve the primary end point (Hazard Ratio, 0.74; 95 % Confidence Interval, 0.56-0.97). CONCLUSIONS: This post hoc subgroup analysis of EPPIC study data suggests that treatment with AST-120 might delay the time to primary end point in CKD patients from the USA. A further randomized controlled trial in progressive CKD patients in the USA is necessary to confirm the beneficial effect of adding AST-120 to standard therapy regimens. TRIAL REGISTRATION: ClinicalTrials.gov NCT00500682 ; NCT00501046 . PMID- 27716150 TI - Prevalence of short stature, underweight, overweight, and obesity among school children in Jordan. AB - BACKGROUND: The prevalence of short stature (SS) and underweight in Jordan on a national level is unknown. This study aimed to investigate, on a national level, the prevalence of short stature (SS), underweight, overweight, and obesity among school aged children in Jordan. METHODS: This cross-sectional study was conducted from May 2015 to January 2016 and included 2702 subjects aged 6-17 years. Jordan was classified into 3 regions; North, Center (urban), and South (rural). Public and private schools were randomly selected from a random sample of cities from each region. The socioeconomic status of the sampling locations was assessed using several indicators including education, income, healthcare and housing conditions. For each participating subject, anthropometrics were obtained. SS, underweight, overweight and obesity were defined using Center of Disease Control's (CDC) growth charts. Median Z-scores for each region, age and gender were calculated. RESULTS: The Central and Northern regions enjoyed higher socioeconomic status compared to rural Southern regions. The overall prevalence of SS, underweight, overweight, and obesity were 4.9 %, 5.7 %, 17.3 %, and 15.7 %, respectively. SS and underweight were most prevalent in the rural South, while obesity was highest in the Central region. Females were more likely to be overweight, while males were more likely to be obese. Private schools had higher prevalence of obesity and overweight than public ones. CONCLUSIONS: Variations in height and weight among Jordanian school children might be affected by socioeconomic status. PMID- 27716151 TI - The associations between domain-specific sedentary behaviours and dietary habits in European adults: a cross-sectional analysis of the SPOTLIGHT survey. AB - BACKGROUND: Sedentary behaviour has been associated with obesity and related chronic diseases. Disentangling the nature of this association is complicated due to interactions with other lifestyle factors, such as dietary habits, yet limited research has investigated the relation between domain-specific sedentary behaviours and dietary habits in adults. The aim of this paper was to examine the association between domain-specific sedentary behaviours and dietary habits in adults and to test the moderating effect of age and gender on this association. METHODS: A total of 6,037 participants from five urban regions in Europe completed an online survey, of which 6,001 were included in the analyses. Multilevel mixed-effects logistic regression analyses were used to examine main associations and interaction effects. RESULTS: All domain-specific sedentary behaviours, except transport-related sitting time, were significantly related to dietary habits. In general, having a higher sitting time was related to having less healthy dietary habits, especially for television viewing. Gender did not moderate any of the relations, and age was only a significant moderator in the relation between other leisure sitting time and alcohol consumption. CONCLUSION: Domain-specific sitting behaviours were related to unhealthy dietary behaviours. However, the small effect sizes suggest that individual level behavioural interventions focusing on sedentary behaviour will not be sufficient to improve dietary habits. The fact that almost none of the associations were moderated by age or gender suggests that these associations, and possibly also the effects of interventions targeting both behaviours, may hold across age and gender groups. PMID- 27716153 TI - Evaluation of bond strength of various epoxy resin based sealers in oval shaped root canals. AB - BACKGROUND: The aim of this study was to evaluate the bond strength of AH plus, Acroseal, and Adseal to the root canal dentin. METHODS: A total of 36 single rooted, mandibular premolar teeth were used. Root canal shaping procedures were performed with ProTaper rotary instruments (Dentsply Maillefer) up to size F4. The prepared samples were then randomly assembled into 3 groups (n = 12). For each group, an ultrasonic tip (size 15, 0.02 taper) which was also coated with an epoxy resin based sealer and placed 2 mm shorter than the working length. The sealer was then activated for 10 s. A push-out test was used to measure the bond strength between the root canal dentine and the sealer. Kruskal-Wallis test to evaluate the push-out bond strength of epoxy based sealer (P = 0.05). The failure mode data were statistically analyzed using Pearson's chi square test (P = 0.05). RESULTS: Kruskal-Wallis test indicated that there were no statistically significant difference among the push out bond strength values of 3 mm (p = 0.123) and 6 mm (P = 0.057) for groups, there was statistically significant difference push out bond strength value of 9 mm (P = 0.032). Pearson's chi square test showed statistically significant differences for the failure types among the groups. CONCLUSION: Various epoxy resin based sealers activated ultrasonically showed similar bond strength in oval shaped root canals. Apical sections for all groups have higher push out bond strength values than middle and coronal sections. PMID- 27716152 TI - Rationale and design of the Children's Oncology Group (COG) study ALTE1621: a randomized, placebo-controlled trial to determine if low-dose carvedilol can prevent anthracycline-related left ventricular remodeling in childhood cancer survivors at high risk for developing heart failure. AB - BACKGROUND: Anthracyclines are widely used in the treatment of childhood cancer. One of the well-recognized side-effects of anthracycline therapy is dose dependent cardiomyopathy that may progress to heart failure (HF) years after completion of cancer-directed therapy. This study will evaluate the efficacy of low-dose beta-blocker (carvedilol) for HF risk reduction in childhood cancer survivors at highest risk for HF. The proposed intervention has the potential to significantly reduce chronic cardiac injury via interruption of neurohormonal systems responsible for left ventricular (LV) remodeling, resulting in improved cardiac function and decreased risk of HF. The intervention is informed by previous studies demonstrating efficacy in pediatric and adult non-oncology populations, yet remains unstudied in the pediatric oncology population. METHODS/DESIGN: The primary objective of the trial is to determine impact of the intervention on echocardiographic markers of cardiac remodeling and HF risk, including: LV wall thickness/ dimension ratio (LVWT/D; primary endpoint), as well as LV ejection fraction, volume, and blood biomarkers (natriuretic peptides, galectin-3) associated with HF risk. Secondary objectives are to establish safety and tolerability of the 2-year course of carvedilol using: 1) objective measures: hepatic and cardiovascular toxicity, treatment adherence, and 2) subjective measures: participant self-reported outcomes. Two hundred and fifty survivors of childhood cancer (diagnosed <21 years of age), and previously treated with high dose (>=300 mg/m2) anthracyclines will be enrolled in a randomized, double-blind, placebo controlled trial. After baseline assessments, participants will be randomized in a 1:1 ratio to low-dose carvedilol (maximum dose: 12.5 mg/day) or placebo. Carvedilol or placebo is up-titrated (starting dose: 3.125 mg/day) according to tolerability. DISCUSSION: When completed, this study will provide much-needed information regarding a physiologically plausible pharmacological risk-reduction strategy for childhood cancer survivors at high risk for developing anthracycline-related HF.

PMID- 27716154 TI - Effect of the herbal mixture composed of Aloe Vera, Henna, Adiantum capillus veneris, and Myrrha on wound healing in streptozotocin-induced diabetic rats. AB - BACKGROUND: Wound healing is often impaired in diabetic animals and humans. Matrix metalloproteases act as pro-inflammatory agents in physiological wound healing pathways by stimulating cytokines including the interleukins, IL6, IL1A and IL1B, and the tumor necrosis factor and transforming growth factor beta1. Botanicals are traditionally used to assist healing of different types of wounds, because they produce fewer side effects. Our specific aim here was to develop a plant-based recipe supporting effective wound healing in diabetic animals. METHODS: Plant materials from Adiantum capillus-veneris, Commiphora molmol, Aloe Vera, and henna were collected for this study, and oven-dried at 60 degrees C. The dried leaves and resins were then crumbled into a powder and mixed in equal parts with Vaseline as a preservative. This mixture was used as an ointment on wounds induced in 60 diabetic and non-diabetic rats that were divided into 6 subgroups receiving agent or control treatments. Necrotic tissue surrounding the wound was periodically removed during wound healing. RNA was extracted from the healing region of the wound at days 7, 14 and 21 for cDNA synthesis to monitor changes in Tgfb1, Mmp3, Mmp9, Il6 and Tnf alpha expression using real-time PCR. RESULTS: The expression of the Mmp3, the Tnf alpha, and the Tgfb1 genes from wound tissue were significantly different (p < 0.05) between diabetic and non diabetic (control) rats treated with the herbal mixture after 14 and 21 days. There was no significant difference (p > 0.05) of the Mmp9 gene expression in diabetic and non-diabetic rats treated only with Vaseline after 7, 14, and 21 days. But, the expression of the Mmp9 gene decreased significantly (p < 0.05) in diabetic rats after 14 days in comparison to non-diabetic rats, when the herbal mixture was added to Vaseline. CONCLUSIONS: Our study presents an herbal treatment that alters the gene expression signature at wounds induced in the rat model for type I diabetes in a manner consistent with accelerated healing, and demonstrates that this herbal treatment might be effective to treat wounds in diabetic patients. PMID- 27716155 TI - Specialty preferences among final year medical students in medical schools of southeast Nigeria: need for career guidance. AB - BACKGROUND: In resource-poor settings with low doctor-population ratio, there is need for equitable distribution of healthcare workforce. The specialty preferences of medical students determine the future composition of physician workforce hence its relevance in career guidance, healthcare planning and policy formulation. This study was aimed at determining the specialty preferences of final year medical students in medical schools of southeast Nigeria, the gender differences in choice of specialty and the availability of career guidance to the students during the period of training. METHODS: A descriptive cross-sectional study was conducted among final year medical students in the six accredited medical schools in southeast Nigeria using self-administered semi-structured questionnaire. Information on reason for studying Medicine, specialty preference and career guidance were obtained. Chi-square test of statistical significance was used in the analysis. RESULTS: A total of 457 students participated in the study with a response rate of 86.7 %. The mean age was 25.5 +/- 2.9 years and 57.1 % were male. Majority (51 %) opted to study Medicine in-order to save lives while 89.5 % intended to pursue postgraduate medical training. A higher proportion (51.8 %) made the decision during the period of clinical rotation. The five most preferred specialties among the students were Surgery (24.0 %); Paediatrics (18.8 %); Obstetrics and Gynaecology (15.6 %); Internal Medicine (11.0 %) and Community Medicine (6.8 %) while Pathology (2.0 %); Anaesthesia (0.7 %) and Ear, Nose and Throat (0.2 %), were the least preferred. Compared to females, a higher proportion of male students intended to specialise in Surgery (32.3 % vs 13.0 %, p < 0.001) in contrast to Paediatrics (11.2 % vs 28.8 %, p < 0.001). Majority of the students, 74.6 % had no form of career guidance during their stay in medical school and 11.2 % were undecided on choice of specialty. CONCLUSION: In spite of the high proportion of students willing to pursue specialist medical training after graduation, most opted for the four core clinical specialities of Surgery, Paediatrics, Obstetrics and Gynaecology and Internal Medicine. Majority of the students made these decisions during clinical rotations. Also, majority had no form of career guidance throughout their stay in medical school. To ensure an equitable distribution of a limited physician workforce in a resource-poor setting, there is need for proper career guidance for the students and this should be in line with the national health needs. PMID- 27716156 TI - An empirical study of the 'underscreened' in organised cervical screening: experts focus on increasing opportunity as a way of reducing differences in screening rates. AB - BACKGROUND: Cervical cancer disproportionately burdens disadvantaged women. Organised cervical screening aims to make cancer prevention available to all women in a population, yet screening uptake and cancer incidence and mortality are strongly correlated with socioeconomic status (SES). Reaching underscreened populations is a stated priority in many screening programs, usually with an emphasis on something like 'equity'. Equity is a poorly defined and understood concept. We aimed to explain experts' perspectives on how cervical screening programs might justifiably respond to 'the underscreened'. METHODS: This paper reports on a grounded theory study of cervical screening experts involved in program organisation. Participants were 23 experts from several countries and a range of backgrounds: gynecology; epidemiology; public health; pathology; general practice; policy making. Data were gathered via semi-structured interview and concepts developed through transcript coding and memo writing. RESULTS: Most experts expressed an intuitive commitment to reducing systematic differences in screening participation or cancer outcomes. They took three different implicit positions, however, on what made organised programs justifiable with respect to underscreened populations. These were: 1) accepting that population screening is likely to miss certain disenfranchised groups for practical and cultural reasons, and focusing on maximising mainstream reach; 2) identifying and removing barriers to screening; and 3) providing parallel tailored screening services that attended to different cultural needs. Positions tended to fall along country of practice lines. CONCLUSIONS: Experts emphasised the provision of opportunity for underscreened populations to take up screening. A focus on opportunity appeared to rely on tacit premises not supported by evidence: that provision of meaningful opportunity leads to increased uptake, and that increased uptake of an initial screening test by disadvantaged populations would decrease cervical cancer incidence and mortality. There was little attention to anything other than the point of testing, or the difficulties disadvantaged women can have in accessing follow up care. The different approaches to 'improving equity' taken by participants are differently justified, and differently justifiable, but none attend directly to the broader conditions of disadvantage. PMID- 27716157 TI - Effects of a fixed low-dose ropivacaine with different volume and concentrations on interscalene brachial plexus block: a randomized controlled trial. AB - BACKGROUND: Ultrasound guidance has reduced the amount of local anesthetics to achieve a successful block. Previous studies of the relationship between the volume or concentration of local anesthetics and the effects of the block were based on relatively high doses of local anesthetics. We tested the hypothesis that providing low dose of ropivacaine at three combinations of volumes and concentrations for ultrasound-guided interscalene brachial plexus block would produce different effects in the aspect of onset time, pain control and the incidence of side effects. METHODS: Ninety-nine patients undergoing elective arthroscopic shoulder surgery were randomized to receive an ultrasound guided combined with nerve stimulator mediated interscalene block with ropivacaine 0.75 % (6.7 ml, Group 0.75), 0.5 % (10 ml, Group 0.5) or 0.25 % (20 ml, Group 0.25). The primary end point was the onset time of the sensory blockade, assessed by using a pinprick in the C5-6 dermatome. The secondary end points included the onset time of the motor blockade, block success rate, postoperative pain rating score, rescue analgesics requirement, sleep quality, strength of the hand on the block side,and the incidence of hemi-diaphragmatic paresis which was evaluated by ultrasonography. RESULTS: There was a statistically significant difference of the sensory block median onset times among Group 0.75 (5 min), Group 0.5 (10 min) and Group 0.25 (20 min). One patient in Group 0.5 and 20 patients in Group 0.25 did not achieve a complete motor block within 30 min, which were also significantly different. No significant difference was observed in postoperative analgesia, decrease of handgrip strength and the incidence of hemi-diaphragmatic paresis among the 3 groups. CONCLUSIONS: This study demonstrates that ropivacaine 50 mg as 0.25, 0.5 or 0.75 % solution for interscalene brachial plexus block before arthroscopic shoulder surgery produces comparable blockade with few side effects, while 0.75 % seems to be more preferable as it is associated with faster onset time. TRIAL REGISTRATION: ChiCTR-TRC-13004058 . Registered 4 December 2013. PMID- 27716158 TI - Effect of chondroitin sulfate on soluble biomarkers of osteoarthritis: a method to analyze and interpret the results from an open-label trial in unilateral knee osteoarthritis patients. AB - BACKGROUND: The aim of this study was to investigate the effects of chondroitin sulfate (CS) on the serum levels of Coll2-1 in patients with knee OA. METHODS: Seventy two patients with unilateral symptomatic knee OA were involved in a post authorization open-label study evaluating CS (800 mg/day). The primary outcome was the % relative change in serum Coll2-1 (sColl2-1). The secondary outcomes were the evaluation of pain (VAS) and function (Lequesne's Index). Responders and non-responders were classified according to OMERACT-OARSI recommendations. Finally, an original cut-off method was applied to categorize patients and interpret individual variations in serum levels of Coll2-1. RESULTS: Patients showed no difference in the sColl2-1 levels at baseline. When considering responders and non-responders from the ITT population, a significant difference was found for Coll2-1 at 3 months (p = 0.030) and 6 months (p = 0.038). A decrease in pain (VAS) and an improvement in function (LI) were recorded throughout the visits (p < 0.01). Considering an intra-batch cut-off of 21 %, CS decreased Coll2-1 serum levels between baseline and 1-month visit compared to the value of Coll2-1 before treatment (screening visit) which can be interpreted as a drastic reduction of the proportion of patients with an increase of Coll2-1 over 21 % (reduction from 13 to 3 %). It also consisted in a more important proportion of patients with a decrease in Coll2-1 (from 5 to 10 %). CONCLUSION: This study proposes a new approach for the analysis and the interpretation of the individual variation in biomarker levels and introduces the notion of metabolic responders. TRIAL REGISTRATION: ID ISRCTN63795830 . The trial was retrospectively registered on 2 October, 2015. PMID- 27716160 TI - Extracts of six Rubiaceae species combined with rifampicin have good in vitro synergistic antimycobacterial activity and good anti-inflammatory and antioxidant activities. AB - BACKGROUND: The Rubiaceae family has played a significant role in drug discovery by providing molecules with potential use as templates for the development of therapeutic drugs. This study was designed to study the in vitro synergistic effect of six Rubiaceae species in combination with a known anti-TB drug. The antioxidant and anti-inflammatory activity of these species were also evaluated to investigate additional benefits in antimycobacterial treatment. METHODS: The checkerboard method was used to determine the antimycobacterial synergistic activity of plant extracts combined with rifampicin. The antioxidant activity of extracts was determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. Anti inflammatory activity via inhibition of nitric oxide (NO) production was performed in LPS-activated RAW 264.7 macrophages using the Griess assay. RESULTS: Combination of rifampicin with the crude extracts resulted in a 4 to 256-fold increase of activity of extracts. The crude extract of Cremaspora triflora produced the best synergistic effect with rifampicin, with a fractional inhibitory concentration (FIC) index of 0.08 against Mycobacterium aurum. Extracts of Psychotria zombamontana had the best antioxidant activity with an IC50 value of 1.77 MUg/mL, lower than the IC50 of trolox and ascorbic acid (5.67 MUg/mL and 4.66 MUg/mL respectively). All the extracts tested inhibited nitric oxide (NO) production in a concentration dependent manner with the percentage of inhibition varying from 6.73 to 86.27 %. CONCLUSION: Some of the Rubiaceae species investigated have substantial in vitro synergistic effects with rifampicin and also good free radical scavenging ability and anti-inflammatory activity. These preliminary results warrant further study on these plants to determine if compounds isolated from these species could lead to the development of bioactive compounds that can potentiate the activity of rifampicin even against resistant mycobacteria. PMID- 27716161 TI - Using program evaluation to support knowledge translation in an interprofessional primary care team: a case study. AB - BACKGROUND: Evaluation is a fundamental component in building quality primary care and is ideally situated to support individual, team and organizational learning by offering an accessible form of participatory inquiry. The evaluation literature has begun to recognize the unique features of KT evaluations and has described attributes to consider when evaluating KT activities. While both disciplines have focused on the evaluation of KT activities neither has explored the role of evaluation in KT. The purpose of the paper is to examine how participation in program evaluation can support KT in a primary care setting. METHODS: A mixed methods case study design was used, where evaluation was conceptualized as a change process and intervention. A Memory Clinic at an interprofessional primary care clinic was the setting in which the study was conducted. An evaluation framework, Pathways of Influence provided the theoretical foundation to understand how program evaluation can facilitate the translation of knowledge at the level of the individual, inter-personal (Memory Clinic team) and the organization. Data collection included questionnaires, interviews, evaluation log and document analysis. Questionnaires and interviews were administered both before and after the evaluation: Pattern matching was used to analyze the data based on predetermined propositions. RESULTS: Individuals gained program knowledge that resulted in changes to both individual and program practices. One of the key themes was the importance clinicians placed on local, program based knowledge. The evaluation had less influence on the broader health organization. CONCLUSIONS: Program evaluation facilitated individual, team and organizational learning. The use of evaluation to support KT is ideally suited to a primary care setting by offering relevant and applicable knowledge to primary care team members while being sensitive to local context. PMID- 27716159 TI - The clinical and cost effectiveness of steroid injection compared with night splints for carpal tunnel syndrome: the INSTINCTS randomised clinical trial study protocol. AB - BACKGROUND: Patients diagnosed with idiopathic mild to moderate carpal tunnel syndrome (CTS) are usually managed in primary care and commonly treated with night splints and/or corticosteroid injection. The comparative effectiveness of these interventions has not been reliably established nor investigated in the medium and long term. The primary objective of this trial is to investigate whether corticosteroid injection is effective in reducing symptoms and improving hand function in mild to moderate CTS over 6 weeks when compared with night splints. Secondary objectives are to determine specified comparative clinical outcomes and cost effectiveness of corticosteroid injection over 6 and 24 months. METHOD/DESIGN: A multicentre, randomised, parallel group, clinical pragmatic trial will recruit 240 adults aged >=18 years with mild to moderate CTS from GP Practices and Primary-Secondary Care Musculoskeletal Interface Clinics. Diagnosis will be by standardised clinical assessment. Participants will be randomised on an equal basis to receive either one injection of 20 mg Depo-Medrone or a night splint to be worn for 6 weeks. The primary outcome is the overall score of the Boston Carpal Tunnel Questionnaire (BCTQ) at 6 weeks. Secondary outcomes are the BCTQ symptom severity and function status subscales, symptom intensity, interrupted sleep, adherence to splinting, perceived benefit and satisfaction with treatment, work absence and reduction in work performance, EQ-5D-5L, referral to surgery and health utilisation costs. Participants will be assessed at baseline and followed up at 6 weeks, 6, 12 and 24 months. The primary analysis will use an intention to treat (ITT) approach and multiple imputation for missing data. The sample size was calculated to detect a 15 % greater improvement in the BTCQ overall score in the injection group compared to night-splinting at approximately 90 % power, 5 % two-tailed significance and allows for 15 % loss to follow-up. DISCUSSION: The trial makes an important contribution to the evidence base available to support effective conservative management of CTS in primary care. No previous trials have directly compared these treatments for CTS in primary care populations, reported on clinical effectiveness at more than 6 months nor compared cost effectiveness of the interventions.

PMID- 27716162 TI - Effectiveness of enhanced cognitive behavioral therapy (CBT-E) in the treatment of anorexia nervosa: a prospective multidisciplinary study. AB - BACKGROUND: Anorexia nervosa (AN) is a debilitating psychiatric disorder associated with a wide array of negative health complications and psychiatric comorbidity. Existing evidence for AN treatment in adults is weak, and no empirically supported treatment has been reliably established. The primary objective of this study is to gain knowledge about the effectiveness of enhanced cognitive behavioral therapy (CBT-E) for anorexia nervosa delivered in a public hospital setting. Baseline predictors of treatment outcome and dropout are studied. Furthermore, there will be collected blood and stool samples for a general biobank to be able to initiate research on possible pathophysiological mechanisms underlying AN. METHODS: The study will assess the potency of outpatient CBT-E in a sample of patients suffering from AN (age >16) admitted to the Section for Eating Disorders at the Department for Psychosomatic Medicine, Haukeland University Hospital in Bergen, Norway. The study has a longitudinal design with five main assessment time points: before treatment, at 3 months, at the end of treatment, at 20 weeks, and at 12 months follow-up including biobank samples. A control group without an eating disorder will also be recruited. DISCUSSION: Treatment research in a public hospital setting is important for gaining knowledge about the transportability of treatments evaluated in research clinics into ordinary clinical practice. Furthermore, biological material from the thoroughly described patient cohort will serve as a basis for further research on the pathophysiological mechanisms in AN.

PMID- 27716163 TI - The expression of 11beta-hydroxysteroid dehydrogenase type 1 is increased in experimental periodontitis in rats. AB - BACKGROUND: The involvement of 11beta-hydroxysteroid dehydrogenase type 1 (11beta HSD1), which converts inactive glucocorticoids into active glucocorticoids intracellularly, in metabolic diseases and chronic inflammatory diseases has been elucidated. We recently reported that an increase in 11beta-HSD1 expression was associated with chronic periodontitis in humans irrespective of obesity. To further clarify the role of 11beta-HSD1 in chronic periodontitis, the expression of 11beta-HSD1 was investigated in experimental periodontitis model in rats. METHODS: Experimental periodontitis was induced by silk ligature of left maxillary second molars of 7-week-old male Wistar rats, and periodontal tissues were collected at day 3. The expression of 11beta-HSD1, 11beta-HSD2, and TNFalpha mRNA was examined using real time reverse transcription-polymerase chain reaction. The expression of TNFalpha was used as an indicator of inflammation. Thus, the rats in which the levels of TNFalpha mRNA were increased in the ligature-induced periodontitis compared with the control were analysed. RESULTS: The findings demonstrated that the expression of 11beta-HSD1 mRNA was significantly increased in experimental periodontitis compared with the control. The increase in the levels of 11beta-HSD1 mRNA in the ligature-induced periodontitis compared with the control was positively correlated with that of TNFalpha mRNA. On the other hand, the expression of 11beta-HSD2 mRNA, which inactivates glucocorticoids, was slightly decreased in experimental periodontitis. Therefore, the ratio of 11beta-HSD1 versus 11beta-HSD2 mRNA was significantly higher in experimental periodontitis than in the control. CONCLUSIONS: These results suggest that the increased expression of 11beta-HSD1, which would result in the increased levels of intracellular glucocorticoids, may play a role in the pathophysiology of experimental periodontitis. PMID- 27716164 TI - Carbapenem-Resistant Klebsiella pneumoniae influences the outcome of early infections in liver transplant recipients. AB - BACKGROUND: Infections remain a leading cause of morbidity and mortality among liver transplant (LT) recipients. The aim of our study was to define the factors associated with outcome of early bacterial and fungal infections in a cohort of patients who underwent LT at the University Hospital of Ancona over a nine year period. METHODS: All consecutive patients who underwent LT in our center were considered. An early infection was defined as occurring in the first month post transplantation. RESULTS: Among 330 patients who underwent LT from August 2005 to October 2014, 88 (27 %) had at least one infection documented within 30 days after transplantation. In 54 cases only one site was involved, in 34 cases >=2 sites. There were 43 (30 %) pneumonia, 40 (27 %) surgical site infections, 31 (22 %) blood stream infections, and 30 (21 %) urinary tract infections. Gram-negative bacteria accounted for 64 % of the culture-positive cases, followed by Gram positive bacteria (30 %) and fungi (6 %). A high proportion of drug-resistant strains was found within either Gram-negative (79 %) or Gram-positive (81 %) bacteria. There were 27 out 88 patients (31 %) who died within 180 days from the transplant. Factors independently associated with a higher risk of mortality were: renal replacement therapy (HR 11.797 [CI95 % 3.082-45.152], p < 0.0001), multisite infections (HR 4.865 [CI95 % 1.417-16.700], p = 0.012) and being infected with carbapenem-resistant Klebsiella pneumoniae (CRKP; HR 5.562 [CI95 % 1.186-26.088], p = 0.030). CONCLUSIONS: Overall, these data indicate that early infections in LT patients are characterized by significant mortality. In particular, an early infection caused by CRKP has an adverse impact on survival in these patients suggesting an urgent need for adopting preventive measures to avoiding this complication. PMID- 27716166 TI - Selection into medical school: from tools to domains. AB - BACKGROUND: Most research into the validity of admissions tools focuses on the isolated correlations of individual tools with later outcomes. Instead, looking at how domains of attributes, rather than tools, predict later success is likely to be more generalizable. We aim to produce a blueprint for an admissions scheme that is broadly relevant across institutions. METHODS: We broke down all measures used for admissions at one medical school into the smallest possible component scores. We grouped these into domains on the basis of a multicollinearity analysis, and conducted a regression analysis to determine the independent validity of each domain to predict outcomes of interest. RESULTS: We identified four broad domains: logical reasoning and problem solving, understanding people, communication skills, and biomedical science. Each was independently and significantly associated with performance in final medical school examinations. CONCLUSIONS: We identified two potential errors in the design of admissions schema that can undermine their validity: focusing on tools rather than outcomes, and including a wide range of measures without objectively evaluating the independent contribution of each. Both could be avoided by following a process of programmatic assessment for selection. PMID- 27716165 TI - A randomized prospective controlled trial comparing the laryngeal tube suction disposable and the supreme laryngeal mask airway: the influence of head and neck position on oropharyngeal seal pressure. AB - BACKGROUND: The Laryngeal Tube Suction Disposable (LTS-D) and the Supreme Laryngeal Mask Airway (SLMA) are second generation supraglottic airway devices (SADs) with an added channel to allow gastric drainage. We studied the efficacy of these devices when using pressure controlled mechanical ventilation during general anesthesia for short and medium duration surgical procedures and compared the oropharyngeal seal pressure in different head and-neck positions. METHODS: Eighty patients in each group had either LTS-D or SLMA for airway management. The patients were recruited in two different institutions. Primary outcome variables were the oropharyngeal seal pressures in neutral, flexion, extension, right and left head-neck position. Secondary outcome variables were time to achieve an effective airway, ease of insertion, number of attempts, maneuvers necessary during insertion, ventilatory parameters, success of gastric tube insertion and incidence of complications. RESULTS: The oropharyngeal seal pressure achieved with the LTS-D was higher than the SLMA in, (extension (p=0.0150) and right position (p=0.0268 at 60 cm H2O intracuff pressures and nearly significant in neutral position (p = 0.0571). The oropharyngeal seal pressure was significantly higher with the LTS-D during neck extension as compared to SLMA (p= 0.015). Similar oropharyngeal seal pressures were detected in all other positions with each device. The secondary outcomes were comparable between both groups. Patients ventilated with LTS-D had higher incidence of sore throat (p = 0.527). No major complications occurred. CONCLUSIONS: Better oropharyngeal seal pressure was achieved with the LTS-D in head-neck right and extension positions , although it did not appear to have significance in alteration of management using pressure control mechanical ventilation in neutral position. The fiberoptic view was better with the SLMA. The post-operative sore throat incidence was higher in the LTS-D.

PMID- 27716167 TI - Prevalence of oral manifestations in children and adolescents with cancer submitted to chemotherapy. AB - BACKGROUND: Oral complications may be observed during chemotherapy and are important side effects that may directly affect the anticancer treatment, even causing septicaemia in some cases. This research was done in order to evaluate changes in oral lesions during follow-up of children and adolescents in chemotherapy at Hospital Estadual Infantil Nossa Senhora da Gloria (HEINSG). METHODS: The study design was longitudinal, 45 patients were evaluated and monitored for 1 month after the initiation of chemotherapy. Twenty-eight patients were male and 17 female, ranging from 3 months to 18 years old. RESULTS: The results show an increase in the number of mucositis cases and a decrease in xerostomia cases after the initiation of treatment, and other oral lesions were also found in low numbers. CONCLUSIONS: It is possible to avoid oral complications by maintaining a good oral health, and reducing infectious outbreaks. It is also feasible to obtain an early diagnosis of, and treat these oral complications, preventing them from following a more severe clinical course that may negatively affect the individual's treatment. This outcome requires the presence of a dental surgeon on the multidisciplinary cancer treatment team. PMID- 27716168 TI - A protocol of a randomized controlled multicenter trial for surgical treatment of lumbar spondylolisthesis: the Lumbar Interbody Fusion Trial (LIFT). AB - BACKGROUND: With a steep increase in the number of instrumented spinal fusion procedures, there is a need for comparative data to develop evidence based treatment recommendations. Currently, the available data on cost and clinical effectiveness of the two most frequently performed surgeries for lumbar spondylolisthesis, transforaminal lumbar interbody fusion (TLIF) and posterior lumbar interbody fusion (PLIF), are not sufficient. Therefore, current guidelines do not advise which is the most appropriate surgical treatment strategy for these patients. Non-randomized studies comparing TLIF and PLIF moreover suggest that TLIF is associated with fewer complications, less blood loss, shorter surgical time and hospital duration. TLIF may therefore be more cost-effective. The results of this study will provide knowledge on short- and long-term clinical and economical effects of TLIF and PLIF procedures, which will lead to recommendations for treating patients with lumbar spondylolisthesis. METHODS: Multicenter blinded Randomized Controlled Trial (RCT; blinding for the patient and statistician, not for the clinician and researcher). A total of 144 patients over 18 years old with symptomatic single level lumbar degenerative, isthmic or iatrogenic spondylolisthesis whom are candidates for LIF (lumbar interbody fusion) surgery through a posterior approach will be randomly allocated to TLIF or PLIF. The study will consist of three parts: 1) a clinical effectiveness study, 2) a cost-effectiveness study, and 3) a process evaluation. The primary clinical outcome measures are: change in disability measured with Oswestry Disability Index (ODI) and change in quality adjusted life years (QALY) measured with EQ-5D-5L. Secondary clinical outcome measures are: Short Form (36) Health Survey (SF-36), VAS back pain, VAS leg pain, Hospital Anxiety Depression Scale (HADS), complications, productivity related costs (iPCQ) and medical costs (iMCQ). Measurements will be carried out at five fixed time points (pre operatively and at 3, 6, 12 and 24 months). DISCUSSION: It is hypothesized that TLIF, compared to PLIF, has similar clinical outcome or is possibly better in reducing disability. Moreover, direct medical costs are expected to be lower due to less surgical morbidity, shorter hospital stay and shorter surgical time. Indirect costs are assumed to be lower for TLIF as well, because we suspect less working days are lost. Currently, prospective data comparing clinical and cost effectiveness of both techniques are not available. Therefore, in clinical practice both techniques are used and the choice for technique is greatly based on surgeon's preference. The demand for spinal fusion surgery has risen steeply over the last 10 years and is expected to increase even further in the near future. As a result, the burden on society (and the working population) will increase. In case our hypothesis is confirmed, treatment guidelines will be adapted, and TLIF will be recommended as first choice surgical treatment of lumbar spondylolisthesis. Ultimately this will lead to reduction of (direct and indirect) costs and better clinical outcome for spondylolisthesis patients eligible for instrumented spinal surgery.

PMID- 27716169 TI - Viscoelastic properties of human and bovine articular cartilage: a comparison of frequency-dependent trends. AB - BACKGROUND: The purpose of this study was to compare the frequency-dependent viscoelastic properties of human and bovine cartilage. METHODS: Full-depth cartilage specimens were extracted from bovine and human femoral heads. Using dynamic mechanical analysis, the viscoelastic properties of eight bovine and six human specimens were measured over the frequency range 1 Hz to 88 Hz. Significant differences between bovine and human cartilage viscoelastic properties were assessed using a Mann-Whitney test (p < 0.05). RESULTS: Throughout the range of frequencies tested and for both species, the storage modulus was greater than the loss modulus and both were frequency-dependent. The storage and loss moduli of all human and bovine cartilage specimens presented a logarithmic relationship with respect to frequency. The mean human storage modulus ranged from 31.9 MPa to 43.3 MPa, while the mean bovine storage modulus ranged from 54.0 MPa to 80.5 MPa; bovine storage moduli were 1.7 to 1.9 times greater than the human modulus. Similarly, the loss modulus of bovine cartilage was 2.0 to 2.1 times greater than human. The mean human loss modulus ranged from 5.3 MPa to 8.5 MPa while bovine moduli ranged from 10.6 MPa to 18.1 MPa. CONCLUSION: Frequency-dependent viscoelastic trends of bovine articular cartilage were consistent with those of human articular cartilage; this includes a similar frequency dependency and high frequency plateau. Bovine cartilage was, however, 'stiffer' than human by a factor of approximately 2. With these provisos, bovine articular cartilage may be a suitable dynamic model for human articular cartilage. PMID- 27716170 TI - Impact of mass-screening on tuberculosis incidence in a prospective cohort of Brazilian prisoners. AB - BACKGROUND: Globally, prison inmates are a high-risk population for tuberculosis (TB), but the specific drivers of disease and impact of mass screening interventions are poorly understood. METHODS: We performed a prospective cohort study to characterize the incidence and risk factors for tuberculosis infection and disease in 12 Brazilian prisons, and to investigate the effect of mass screening on subsequent disease risk. After recruiting a stratified random sample of inmates, we administered a questionnaire to ascertain symptoms and potential risk factors for tuberculosis; performed tuberculin skin testing (TST); collected sera for HIV testing; and obtained two sputum samples for smear microscopy and culture, from participants reporting a cough of any duration. We repeated the questionnaire and all tests for inmates who remained incarcerated after 1 year. TST conversion was defined as TST >=10 mm and an induration increase of at least 6 mm in an individual with a baseline TST <10 mm. Cox proportional hazard models were performed to identify risk factors associated with active TB. To evaluate the impact of screening on subsequent risk of disease, we compared TB notifications over one year among individuals randomized to screening for active TB with those not randomized to screening. RESULTS: Among 3,771 inmates recruited, 3,380 (89.6 %) were enrolled in the study, and 1,422 remained incarcerated after one year. Among 1,350 inmates (94.9 %) with paired TSTs at baseline and one-year follow-up, 25.7 % (272/1060) converted to positive. Among those incarcerated for the year, 10 (0.7 %) had TB at baseline and 25 (1.8 %) were diagnosed with TB over the subsequent year. Cases identified through active screening were less likely to be smear-positive than passively detected cases (10.0 % vs 50.9 %; p < 0.01), suggesting early case detection. However, there was no reduction in subsequent disease among individuals actively screened versus those not screened (1.3 % vs 1.7 %; p = 0.88). Drug use during the year (AHR 3.22; 95 % CI 1.05-9.89) and knows somebody with TB were (AHR 2.86; 95 % CI 1.01 8.10) associated with active TB during one year of follow up CONCLUSIONS: Mass screening in twelve Brazilian prisons did not reduce risk of subsequent disease in twelve Brazilian prisons, likely due to an extremely high force of infection. New approaches are needed to control TB in this high-transmission setting. PMID- 27716171 TI - Coffee and caffeine intake and risk of urinary incontinence: a meta-analysis of observational studies. AB - BACKGROUND: Previous results from studies on the relationship between coffee/caffeine consumption and risk of urinary incontinence (UI) are inconclusive. We aim to assess this association using a meta-analysis of observational studies. METHODS: Pertinent studies were identified by searching electronic database (Embase, PubMed and Web of Science) and carefully reviewing the reference lists of pertinent articles until July 2015. Random-effects models were used to derive the summary ORs and corresponding 95 % CIs. RESULTS: Seven studies (one case-control, two cohort and four cross-sectional) were included in our meta-analysis. The summary ORs for any versus non-consumption were 0.75 (95 % CI 0.54-1.04) for coffee and 1.29 (95 % CI 0.94-1.76) for caffeine consumption. Compared with individuals who never drink coffee, the pooled OR of UI was 0.99 (95 % CI 0.83-1.18) for regular coffee/caffeine drinkers. Coffee/caffeine consumption was not associated with moderate to severe UI (OR 1.18, 95 % CI 0.88 1.58). In stratified analyses by gender, no significant association was found between UI risk and coffee/caffeine consumption in both men (OR 0.99, 95 % CI 0.42-2.32) and women (OR 0.92, 95 % CI 0.80-1.06). By subtype, the pooled ORs were 1.01 (95 % CI 0.86-1.19) for stress UI, 0.99 (95 % CI 0.84-1.16) for urge UI and 0.93 (95 % CI 0.79-1.10) for mixed UI. CONCLUSIONS: This meta-analysis found no evidence for an association between coffee/caffeine consumption and the risk of UI.

PMID- 27716172 TI - Treatment of plaque psoriasis with an ointment formulation of the Janus kinase inhibitor, tofacitinib: a Phase 2b randomized clinical trial. AB - BACKGROUND: Most psoriasis patients have mild to moderate disease, commonly treated topically. Current topical agents have limited efficacy and undesirable side effects associated with long-term use. Tofacitinib is a small molecule Janus kinase inhibitor investigated for the topical treatment of psoriasis. METHODS: This was a 12-week, randomized, double-blind, parallel-group, vehicle-controlled Phase 2b study of tofacitinib ointment (2 % and 1 %) applied once (QD) or twice (BID) daily in adults with mild to moderate plaque psoriasis. Primary endpoint: proportion of patients with Calculated Physician's Global Assessment (PGA-C) clear or almost clear and >=2 grade improvement from baseline at Weeks 8 and 12. Secondary endpoints: proportion of patients with PGA-C clear or almost clear; proportion achieving Psoriasis Area and Severity Index 75 (PASI75) response; percent change from baseline in PASI and body surface area; change from baseline in Itch Severity Item (ISI). Adverse events (AEs) were monitored and clinical laboratory parameters measured. RESULTS: Overall, 435 patients were randomized and 430 patients received treatment. The proportion of patients with PGA-C clear or almost clear and >=2 grade improvement from baseline at Week 8 was 18.6 % for 2 % tofacitinib QD (80 % confidence interval [CI] for difference from vehicle: 3.8, 18.2 %) and 22.5 % for 2 % tofacitinib BID (80 % CI: 3.1, 18.5 %); this was significantly higher vs vehicle for both dosage regimens. No significant difference vs vehicle was seen at Week 12. Significantly more patients achieved PGA-C clear or almost clear with 2 % tofacitinib QD and BID and 1 % tofacitinib QD (not BID) at Week 8, and with 2 % tofacitinib BID at Week 12. Pruritus was significantly reduced vs vehicle with 2 % and 1 % tofacitinib BID (starting Day 2), and 2 % tofacitinib QD (starting Day 3). Overall, 44.2 % of patients experienced AEs, 8.1 % experienced application site AEs, and 2.3 % experienced serious AEs. The highest incidence of AEs (including application site AEs) was in the vehicle QD group. CONCLUSIONS: In adults with mild to moderate plaque psoriasis, 2 % tofacitinib ointment QD and BID showed greater efficacy than vehicle at Week 8, but not Week 12, with an acceptable safety and local tolerability profile.

PMID- 27716175 TI - Relationship between Massachusetts Youth Screening Instrument-second version and psychiatric disorders in youths in welfare and juvenile justice institutions in Switzerland. AB - BACKGROUND: There is growing evidence that it is important to have well standardized procedures for identifying the mental health needs of youths in welfare and juvenile justice institutions. One of the most widely used tools for mental health screening in the juvenile justice system is the Massachusetts Youth Screening Instrument-second version (MAYSI-2). To contribute to the body of research examining the utility of the MAYSI-2 as a mental health screening tool; the first objective of the current study was to examine the relationship between the MAYSI-2 and the Schedule for Affective Disorders and Schizophrenia for School Age Children, Present and Lifetime version (K-SADS-PL) in a sample of Swiss youths in welfare and juvenile justice institutions using a cross-sectional design. Secondly, as the sample was drawn from the French-, German- and Italian speaking parts of Switzerland, the three languages were represented in the total sample and consequently differences between the language regions were analyzed as well. The third objective was to examine gender differences in this relationship. METHODS: Participants were 297 boys and 149 girls (mean age = 16.2, SD = 2.5) recruited from 64 youth welfare and juvenile justice institutions in Switzerland. The MAYSI-2 was used to screen for mental health or behavioral problems that could require further evaluation. Psychiatric classification was based on the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime version (K-SADS-PL). Binomial logistic regression analysis was used to predict (cluster of) psychiatric disorders from MAYSI-2 scales. RESULTS: The regression analyses revealed that the MAYSI-2 scales generally related well to their corresponding homotypic (cluster of) psychiatric disorders. For example, the alcohol/drug use scale identified the presence of any substance use disorder and the suicide ideation scale identified youths reporting suicide ideation or suicide attempts. Several MAYSI-2 scales were also related to heterotypic (cluster of) psychiatric disorders. For example, the MAYSI-2 scale alcohol/drug use, was positively related to any disruptive disorder. Furthermore, the results revealed gender differences in the relationship between the MAYSI-2 and K-SADS-PL (e.g., in the boys' subsample no MAYSI-2 scale was significantly related to any affective disorder; whereas, in the girls' subsample the MAYSI-2 scales depressed-anxious and somatic complaints were significantly related to any affective disorder). CONCLUSIONS: Overall, The MAYSI-2 seems to serve well as a first-stage screen to identify service needs for youths in welfare and juvenile justice institutions in Switzerland. Its effectiveness to identify the presence of (cluster of) psychiatric disorders differs between genders. PMID- 27716176 TI - Relation between BCG vaccine scar and an interferon-gamma release assay in immigrant children with "positive" tuberculin skin test (>=10 mm). AB - BACKGROUND: Immigrants from countries with high incidence of tuberculosis (TB) are usually offered screening when they arrive to low incidence countries. The tuberculin skin test (TST) is often used. The interferon gamma release assays (IGRAs) are more specific and not affected by BCG vaccination. The aims of this study were 1. To see if there if there is a correlation between a positive IGRA (QFT) and presence of a BCG scar in children with TST >=10 mm, 2. To compare the TST diameter with QFT result, 3. To see if chest X-ray can be omitted in QFT negative children despite TST >=10 mm. METHODS: 762 healthy children/adolescents (median age 14 years) arriving to Gothenburg and surroundings with TST >=10 mm were tested with QFT. RESULTS: A total of 163/492 (33 %) children with BCG scar had positive QFT, whereas 205/270 (76 %) without BCG scar had positive QFT (p < 0.0001). The median TST was 12 mm in QFT negative and 18 mm in QFT positive children (p < 0.0001) but with considerable overlap. Median TST was the same (12 mm) in QFT negative children with and without BCG scar. Among the QFT positive children 25/368 had chest X-ray changes compared to 2/393 among the QFT negative children (p < 0.0007). CONCLUSIONS: Previous BCG vaccination had an effect on the TST diameter so an IGRA is recommended to diagnose latent TB. Using only TST for screening of latent TB would lead to overdiagnosis. The TST diameter was larger in QFT positive than in QFT negative children but could not predict QFT in the individual patient. Chest X ray contributes little to the diagnosis of TB in QFT negative children but can not be omitted because of late seroconversion of QFT in some patients. TRIAL REGISTRATION: Not applicable. PMID- 27716178 TI - Securizing data linkage in french public statistics. AB - Administrative records in France, especially medical and social records, have huge potential for statistical studies. The NIR (a national identifier) is widely used in medico-social administrations, and this would theoretically provide considerable scope for data matching, on condition that the legislation on such matters was respected.The law, however, forbids the processing of non-anonymized medical data, thus making it difficult to carry out studies that require several sources of social and medical data.We would like to benefit from computer techniques introduced since the 70 s to provide safe linkage of anonymized files, to release the current constraints of such procedures.We propose an organization and a data workflow, based on hashing and cyrptographic techniques, to strongly compartmentalize identifying and not-identifying data.The proposed method offers a strong control over who is in possession of which information, using different hashing keys for each linkage. This allows to prevent unauthorized linkage of data, to protect anonymity, by preventing cumulation of not-identifying data which can become identifying data when linked.Our proposal would make it possible to conduct such studies more easily, more regularly and more precisely while preserving a high enough level of anonymity.The main obstacle to setting up such a system, in our opinion, is not technical, but rather organizational in that it is based on the existence of a Key-Management Authority. PMID- 27716177 TI - Using a complex adaptive system lens to understand family caregiving experiences navigating the stroke rehabilitation system. AB - BACKGROUND: Family caregivers provide the stroke survivor with social support and continuity during the transition home from a rehabilitation facility. In this exploratory study we examined family caregivers' perceptions and experiences navigating the stroke rehabilitation system. The theories of continuity of care and complex adaptive systems were integrated to examine the transition from a stroke rehabilitation facility to the patient's home. This study provides an understanding of the interacting complexities at the macro and micro levels. METHODS: A convenient sample of family caregivers (n = 14) who provide care for a stroke survivor were recruited 4-12 weeks following the patient's discharge from a stroke rehabilitation facility in Ontario, Canada. Interviews were conducted with family caregivers to examine their perceptions and experiences navigating the stroke rehabilitation system. Directed and inductive content analysis and the theory of Complex Adaptive Systems were used to interpret the perceptions of family caregivers. RESULTS: Health system policies and procedures at the macro level determined the types and timing of information being provided to caregivers, and impacted continuity of care and access to supports and services at the micro-level. Supports and services in the community, such as outpatient physiotherapy services, were limited or did not meet the specific needs of the stroke survivors or family caregivers. CONCLUSION: Relationships with health providers, informational support, and continuity in case management all influence the family caregiving experience and ultimately the quality of care for the stroke survivor, during the transition home from a rehabilitation facility. PMID- 27716179 TI - A knowledge translation intervention to enhance clinical application of a virtual reality system in stroke rehabilitation. AB - BACKGROUND: Despite increasing evidence for the effectiveness of virtual reality (VR)-based therapy in stroke rehabilitation, few knowledge translation (KT) resources exist to support clinical integration. KT interventions addressing known barriers and facilitators to VR use are required. When environmental barriers to VR integration are less amenable to change, KT interventions can target modifiable barriers related to therapist knowledge and skills. METHODS: A multi-faceted KT intervention was designed and implemented to support physical and occupational therapists in two stroke rehabilitation units in acquiring proficiency with use of the Interactive Exercise Rehabilitation System (IREX; GestureTek). The KT intervention consisted of interactive e-learning modules, hands-on workshops and experiential practice. Evaluation included the Assessing Determinants of Prospective Take Up of Virtual Reality (ADOPT-VR) Instrument and self-report confidence ratings of knowledge and skills pre- and post-study. Usability of the IREX was measured with the System Usability Scale (SUS). A focus group gathered therapist experiences. Frequency of IREX use was recorded for 6 months post-study. RESULTS: Eleven therapists delivered a total of 107 sessions of VR-based therapy to 34 clients with stroke. On the ADOPT-VR, significant pre post improvements in therapist perceived behavioral control (p = 0.003), self efficacy (p = 0.005) and facilitating conditions (p =0.019) related to VR use were observed. Therapist intention to use VR did not change. Knowledge and skills improved significantly following e-learning completion (p = 0.001) and was sustained 6 months post-study. Below average perceived usability of the IREX (19th percentile) was reported. Lack of time was the most frequently reported barrier to VR use. A decrease in frequency of perceived barriers to VR use was not significant (p = 0.159). Two therapists used the IREX sparingly in the 6 months following the study. Therapists reported that client motivation to engage with VR facilitated IREX use in practice but that environmental and IREX-specific barriers limited use. CONCLUSIONS: Despite increased knowledge and skills in VR use, the KT intervention did not alter the number of perceived barriers to VR use, intention to use or actual use of VR. Poor perceived system usability had an impact on integration of this particular VR system into clinical practice. PMID- 27716180 TI - Generation of an integrated Hieracium genomic and transcriptomic resource enables exploration of small RNA pathways during apomixis initiation. AB - BACKGROUND: Application of apomixis, or asexual seed formation, in crop breeding would allow rapid fixation of complex traits, economizing improved crop delivery. Identification of apomixis genes is confounded by the polyploid nature, high genome complexity and lack of genomic sequence integration with reproductive tissue transcriptomes in most apomicts. RESULTS: A genomic and transcriptomic resource was developed for Hieracium subgenus Pilosella (Asteraceae) which incorporates characterized sexual, apomictic and mutant apomict plants exhibiting reversion to sexual reproduction. Apomicts develop additional female gametogenic cells that suppress the sexual pathway in ovules. Disrupting small RNA pathways in sexual Arabidopsis also induces extra female gametogenic cells; therefore, the resource was used to examine if changes in small RNA pathways correlate with apomixis initiation. An initial characterization of small RNA pathway genes within Hieracium was undertaken, and ovary-expressed ARGONAUTE genes were identified and cloned. Comparisons of whole ovary transcriptomes from mutant apomicts, relative to the parental apomict, revealed that differentially expressed genes were enriched for processes involved in small RNA biogenesis and chromatin silencing. Small RNA profiles within mutant ovaries did not reveal large-scale alterations in composition or length distributions; however, a small number of differentially expressed, putative small RNA targets were identified. CONCLUSIONS: The established Hieracium resource represents a substantial contribution towards the investigation of early sexual and apomictic female gamete development, and the generation of new candidate genes and markers. Observed changes in small RNA targets and biogenesis pathways within sexual and apomictic ovaries will underlie future functional research into apomixis initiation in Hieracium.

AB - BACKGROUND: In February 2016, a new fungal disease was spotted in wheat fields across eight districts in Bangladesh. The epidemic spread to an estimated 15,000 hectares, about 16 % of the cultivated wheat area in Bangladesh, with yield losses reaching up to 100 %. Within weeks of the onset of the epidemic, we performed transcriptome sequencing of symptomatic leaf samples collected directly from Bangladeshi fields. RESULTS: Reinoculation of seedlings with strains isolated from infected wheat grains showed wheat blast symptoms on leaves of wheat but not rice. Our phylogenomic and population genomic analyses revealed that the wheat blast outbreak in Bangladesh was most likely caused by a wheat infecting South American lineage of the blast fungus Magnaporthe oryzae. CONCLUSION: Our findings suggest that genomic surveillance can be rapidly applied to monitor plant disease outbreaks and provide valuable information regarding the identity and origin of the infectious agent. PMID- 27716182 TI - Self-perceived uselessness is associated with lower likelihood of successful aging among older adults in China. AB - BACKGROUND: Plenty of evidence has shown that self-perceived uselessness among older adults is negatively associated with successful aging in terms of good health in Western societies. It is unclear whether these findings are valid in China where living into older age is more selective due to high mortality at younger ages. METHODS: Using five waves (2000, 2002, 2005, 2008/2009 and 2011/2012) of a large nationally representative survey in China with 29,954 observations from 19,070 older adults aged 65 and older, this study aimed to investigate the association between self-perceived uselessness and successful aging. Self-perceived uselessness was measured by a single item "with age, do you feel more useless?" with six answers: always, often, sometimes, seldom, never, and unable to answer. Successful aging was measured by independence in activities of daily living (ADL), independence in instrumental activities of daily living (IADL), unimpaired cognition, good life satisfaction, and good self-rated health. Logistic regression models were applied to each successful aging indicator after controlling for a rich set of covariates that included demographics, socioeconomic status, family/social support, and health practices. The models also adjusted for intraperson correlations across waves. RESULTS: We found that self-perceived uselessness was negatively associated with successful aging among older adults aged 65 or older. Specifically, compared to never having self perceived uselessness, always having such a perception was associated with 16-42 % lower odds of being ADL independent, IADL independent, cognitively unimpaired, and having good life satisfaction and good self-rated health. Often or sometimes having such a perception also reduced odds of aging successfully, although such reductions were less pronounced. The associations were similar among the oldest old aged 80 or older with one exception for the case of IADL independence. CONCLUSIONS: Self-perceived uselessness is negatively associated with successful aging among Chinese older adults as well as among the oldest-old. Our findings could be informative for China in the development of public health programs that aim to improve self-perceptions about aging and promote successful aging. PMID- 27716183 TI - Development of a video-based education and process change intervention to improve advance cardiopulmonary resuscitation decision-making. AB - BACKGROUND: Advance cardiopulmonary resuscitation (CPR) decision-making and escalation of care discussions are variable in routine clinical practice. We aimed to explore physician barriers to advance CPR decision-making in an inpatient hospital setting and develop a pragmatic intervention to support clinicians to undertake and document routine advance care planning discussions. METHODS: Two focus groups, which involved eight consultants and ten junior doctors, were conducted following a review of the current literature. A subsequent iterative consensus process developed two intervention elements: (i) an updated 'Goals of Patient Care' (GOPC) form and process; (ii) an education video and resources for teaching advance CPR decision-making and communication. A multidisciplinary group of health professionals and policy-makers with experience in systems development, education and research provided critical feedback. RESULTS: Three key themes emerged from the focus groups and the literature, which identified a structure for the intervention: (i) knowing what to say; (ii) knowing how to say it; (iii) wanting to say it. The themes informed the development of a video to provide education about advance CPR decision-making framework, improving communication and contextualising relevant clinical issues. Critical feedback assisted in refining the video and further guided development and evolution of a medical GOPC approach to discussing and recording medical treatment and advance care plans. CONCLUSION: Through an iterative process of consultation and review, video-based education and an expanded GOPC form and approach were developed to address physician and systemic barriers to advance CPR decision-making and documentation. Implementation and evaluation across hospital settings is required to examine utility and determine effect on quality of care. PMID- 27716185 TI - The influence of power and actor relations on priority setting and resource allocation practices at the hospital level in Kenya: a case study. AB - BACKGROUND: Priority setting and resource allocation in healthcare organizations often involves the balancing of competing interests and values in the context of hierarchical and politically complex settings with multiple interacting actor relationships. Despite this, few studies have examined the influence of actor and power dynamics on priority setting practices in healthcare organizations. This paper examines the influence of power relations among different actors on the implementation of priority setting and resource allocation processes in public hospitals in Kenya. METHODS: We used a qualitative case study approach to examine priority setting and resource allocation practices in two public hospitals in coastal Kenya. We collected data by a combination of in-depth interviews of national level policy makers, hospital managers, and frontline practitioners in the case study hospitals (n = 72), review of documents such as hospital plans and budgets, minutes of meetings and accounting records, and non-participant observations in case study hospitals over a period of 7 months. We applied a combination of two frameworks, Norman Long's actor interface analysis and VeneKlasen and Miller's expressions of power framework to examine and interpret our findings RESULTS: The interactions of actors in the case study hospitals resulted in socially constructed interfaces between: 1) senior managers and middle level managers 2) non-clinical managers and clinicians, and 3) hospital managers and the community. Power imbalances resulted in the exclusion of middle level managers (in one of the hospitals) and clinicians and the community (in both hospitals) from decision making processes. This resulted in, amongst others, perceptions of unfairness, and reduced motivation in hospital staff. It also puts to question the legitimacy of priority setting processes in these hospitals. CONCLUSIONS: Designing hospital decision making structures to strengthen participation and inclusion of relevant stakeholders could improve priority setting practices. This should however, be accompanied by measures to empower stakeholders to contribute to decision making. Strengthening soft leadership skills of hospital managers could also contribute to managing the power dynamics among actors in hospital priority setting processes. PMID- 27716184 TI - Amino-acid PET versus MRI guided re-irradiation in patients with recurrent glioblastoma multiforme (GLIAA) - protocol of a randomized phase II trial (NOA 10/ARO 2013-1). AB - BACKGROUND: The higher specificity of amino-acid positron emission tomography (AA PET) in the diagnosis of gliomas, as well as in the differentiation between recurrence and treatment-related alterations, in comparison to contrast enhancement in T1-weighted MRI was demonstrated in many studies and is the rationale for their implementation into radiation oncology treatment planning. Several clinical trials have demonstrated the significant differences between AA PET and standard MRI concerning the definition of the gross tumor volume (GTV). A small single-center non-randomized prospective study in patients with recurrent high grade gliomas treated with stereotactic fractionated radiotherapy (SFRT) showed a significant improvement in survival when AA-PET was integrated in target volume delineation, in comparison to patients treated based on CT/MRI alone. METHODS: This protocol describes a prospective, open label, randomized, multi center phase II trial designed to test if radiotherapy target volume delineation based on FET-PET leads to improvement in progression free survival (PFS) in patients with recurrent glioblastoma (GBM) treated with re-irradiation, compared to target volume delineation based on T1Gd-MRI. The target sample size is 200 randomized patients with a 1:1 allocation ratio to both arms. The primary endpoint (PFS) is determined by serial MRI scans, supplemented by AA-PET-scans and/or biopsy/surgery if suspicious of progression. Secondary endpoints include overall survival (OS), locally controlled survival (time to local progression or death), volumetric assessment of GTV delineated by either method, topography of progression in relation to MRI- or PET-derived target volumes, rate of long term survivors (>1 year), localization of necrosis after re-irradiation, quality of life (QoL) assessed by the EORTC QLQ-C15 PAL questionnaire, evaluation of safety of FET-application in AA-PET imaging and toxicity of re-irradiation. DISCUSSION: This is a protocol of a randomized phase II trial designed to test a new strategy of radiotherapy target volume delineation for improving the outcome of patients with recurrent GBM. Moreover, the trial will help to develop a standardized methodology for the integration of AA-PET and other imaging biomarkers in radiation treatment planning. TRIAL REGISTRATION: The GLIAA trial is registered with ClinicalTrials.gov ( NCT01252459 , registration date 02.12.2010), German Clinical Trials Registry ( DRKS00000634 , registration date 10.10.2014), and European Clinical Trials Database (EudraCT-No. 2012-001121-27, registration date 27.02.2012). PMID- 27716186 TI - Quality of diabetes care and health insurance coverage: a retrospective study in an outpatient academic public hospital in Switzerland. AB - BACKGROUND: Socioeconomic disadvantage is associated with an increased risk of adverse diabetes outcomes. In Switzerland, a country with theoretical universal healthcare coverage, people without health insurance face barriers in accessing to and in receiving standard quality care. The Geneva University Hospitals (HUG) have implemented policies aiming at reducing these gaps. We compared quality of diabetes care and ambulatory healthcare services utilization among insured and uninsured diabetic patients. METHODS: This retrospective study linked health and administrative data of type 2 diabetic outpatients with at least one HbA1c test performed in 2012-2013 at HUG. Quality of care evaluation relied on processes (annual serum HbA1c, cholesterol and microalbuminuria tesing) and outcomes (HbA1c) assessment. Healthcare utilization was assessed by the number of ambulatory clinical and laboratory visits. Results were stratified by disease course (newly diagnosed versus prevalent diabetes). RESULTS: Of the 198 patients included, 80 (40.4 %) were uninsured. Both groups underwent annual testing of HbA1c, cholesterol, kidney function and microalbuminuria at comparably high rates and numbers of ambulatory visits did not significantly differ. After adjustments for age and sex, there were no significant differences in serum HbA1c between groups both in those with prevalent or with newly diagnosed diabetes. Initial medical intervention entailed comparable glycaemic improvement after 6 months in incident diabetes among insured and uninsured patients. CONCLUSIONS: This study did not find any difference in quality of diabetes care between insured and uninsured patients in a public hospital enforcing health-equity policies for access to and for delivery of standard diabetes care. It highlights the frontline role of public hospitals in contributing to care delivery equity even in countries with theoretical universal healthcare coverage. PMID- 27716188 TI - Circle of care modelling: an approach to assist in reasoning about healthcare change using a patient-centric system. AB - BACKGROUND: Many health system and health Information and Communication Technology (ICT) projects do not achieve their expected benefits. This paper presents an approach to exploring changes in the healthcare system to better understand the expected improvements and other changes by using a patient-centric modelling approach. Circle of care modeling (CCM) was designed to assist stakeholders in considering healthcare system changes using a patient centric approach. METHODS: The CCM approach is described. It includes four steps, based on soft systems methodology: finding out, conceptual modelling, structured discussion, and describing potential improvements. There are four visualizations that are used though this process: patient-persona based rich pictures of care flows (as part of finding out), and three models: provider view, communication view, and information repository view (as part of conceptual modelling). RESULTS: Three case studies are presented where CCM was applied to different real-world healthcare problems: 1. Seeking improvements in continuity of care for end of life patients. 2. Exploring current practices for medication communication for ambulatory patients prior to an update of a jurisdictional drug information system. 3. Deciding how to improve attachment of patients to primary care. The cases illustrate how CCM helped stakeholders reason from a patient centered approach about gaps and improvements in care such as: data fragmentation (in 1), coordination efforts of medication management (in 2), and deciding to support a community health centre for unattached patients (in 3). DISCUSSION: The circle of care modelling approach has proved to be a useful tool in assisting stakeholders explore health system change in a patient centric approach. It is one way to instantiate the important principle of being patient centered into practice when considering health system changes. PMID- 27716187 TI - A three perspective study of the sense of home of nursing home residents: the views of residents, care professionals and relatives. AB - BACKGROUND: The sense of home of nursing home residents is a multifactorial phenomenon which is important for the quality of living. This purpose of this study is to investigate the factors influencing the sense of home of older adults residing in the nursing home from the perspective of residents, relatives and care professionals. METHODS: A total of 78 participants (n = 24 residents, n = 18 relatives and n = 26 care professionals) from 4 nursing homes in the Netherlands engaged in a qualitative study, in which photography was as a supportive tool for subsequent interviews and focus groups. The data were analyzed based on open ended coding, axial coding and selective coding. RESULTS: The sense of home of nursing home residents is influenced by a number of jointly identified factors, including the building and interior design; eating and drinking; autonomy and control; involvement of relatives; engagement with others and activities; quality of care are shared themes. Residents and relatives stressed the importance of having a connection with nature and the outdoors, as well as coping strategies. Relatives and care professionals emphasized the role the organization of facilitation of care played, as well as making residents feel like they still matter. CONCLUSIONS: The sense of home of nursing home residents is influenced by a multitude of factors related to the psychology of the residents, and the social and built environmental contexts. A holistic understanding of which factors influence the sense of home of residents can lead to strategies to optimize this sense of home. This study also indicated that the nursing home has a dual nature as a place of residence and a place where people are supported through numerous care strategies. PMID- 27716189 TI - Awareness and implementation of nine World Health Organization's patient safety solutions among three groups of healthcare workers in Oman. AB - BACKGROUND: The pressing need to reduce burgeoning poor safety measures affecting millions worldwide has alerted World Health Assembly to set-up mechanisms to increase patient safety. In response to such needs, World Health Organization (WHO) formulated nine life-saving patient safety solutions that would be essential to lower reduce healthcare-related harm. There is a paucity of research examining awareness of such nine patient safety solutions. This study has been designed and conducted to compare self-estimated awareness and practice of the World Health Organization's nine "Life-saving Patient Safety Solutions" aide memoirs among different groups of healthcare workers in Oman. METHODS: All nationwide healthcare workers (nurses, physicians and allied health professionals) in hospitals and primary healthcare under the auspice of Ministry of Health were the target population of this survey. Participants were selected by a simple, systematic random sampling from the list of staff in each representative institution. The study was conducted from November 2012 to February 2013. A total of 800 participants (590 from health centers and 210 from hospitals) were invited to participate in this study. RESULTS: A total number of 763 healthcare professionals consented to participate. The overall response rate was 95 % with the majority being nurses, female staff and who had an average of more than 4 years of experience. Overall, 85 % of the participants self-estimated awareness of the nine life-saving patient safety solutions showed the nurses being the most aware, followed by physicians with the allied health professionals showing suboptimal awareness. The primary healthcare center staff demonstrated higher awareness compared to hospital staff. There was a complex relationship between health professional's age, place of work and awareness and practice. CONCLUSION: This study lays the foundation for international comparisons of self estimated awareness and practice towards nine patient safety solutions. The data from Oman indicates the need for more attention to be directed towards heightening awareness and practice of the nine patient safety solutions. PMID- 27716190 TI - "I go I die, I stay I die, better to stay and die in my house": understanding the barriers to accessing health care in Timor-Leste. AB - BACKGROUND: Despite public health care being free at the point of delivery in Timor-Leste, wealthier patients access hospital care at nearly twice the rate of poorer patients. This study seeks to understand the barriers driving inequitable utilisation of hospital services in Timor-Leste from the perspective of community members and health care managers. METHODS: This multisite qualitative study in Timor-Leste conducted gender segregated focus groups (n = 8) in eight districts, with 59 adults in urban and rural settings, and in-depth interviews (n = 8) with the Director of community health centres. Communication was in the local language, Tetum, using a pre-tested interview schedule. Approval was obtained from community and national stakeholders, with written consent from participants. RESULTS: Lack of patient transport is the critical cross-cutting issue preventing access to hospital care. Without it, many communities resort to carrying patients by porters or on horseback, walking or paying for (unaffordable) private arrangements to reach hospital, or opt for home-based care. Other significant out of-pocket expenses for hospital visits were blood supplies from private suppliers; accommodation and food for the patient and family members; and repatriation of the deceased. Entrenched nepotism and hospital staff denigrating patients' hygiene and personal circumstances were also widely reported. Consequently, some respondents asserted they would never return to hospital, others delayed seeking treatment or interrupted their treatment to return home. Most considered traditional medicine provided an affordable, accessible and acceptable substitute to hospital care. Obtaining a referral for higher level care was not a significant barrier to gaining access to hospital care. CONCLUSIONS: Onerous physical, financial and socio-cultural barriers are preventing or discouraging people from accessing hospital care in Timor-Leste. Improving access to quality primary health care at the frontline is a key strategy for ensuring universal access to health care, pursued alongside initiatives to overcome the multi-faceted barriers to hospital care experienced by the vulnerable. Improving the availability and functioning of patient transport services, provision of travel subsidies to patients and their families and training hospital staff in standards of professional care are some options available to government and donors seeking faster progress towards universal health coverage in Timor-Leste. PMID- 27716191 TI - Comparison of different methods of splenic hilar lymph node dissection for advanced upper- and/or middle-third gastric cancer. AB - BACKGROUND: Surgery for advanced gastric cancer (AGC) often includes dissection of splenic hilar lymph nodes (SHLNs). This study compared the safety and effectiveness of different approaches to SHLN dissection for upper- and/or middle third AGC. METHODS: We retrospectively compared and analyzed clinicopathologic and follow-up data from a prospectively collected database at the Peking University Cancer Hospital. Patients were divided into three groups: in situ spleen-preserved, ex situ spleen-preserved and splenectomy. RESULTS: We analyzed 217 patients with upper- and/or middle-third AGC who underwent R0 total or proximal gastrectomy with splenic hilar lymphadenectomy from January 2006 to December 2011, of whom 15.2 % (33/217) had metastatic SHLNs, and from whom 11.4 % (53/466) of the dissected SHLNs were metastatic. The number of harvested SHLNs per patient was higher in the ex situ group than in the in situ group (P = 0.017). Length of postoperative hospital stay was longer in the splenectomy group than in the in situ group (P = 0.002) or the ex situ group (P < 0.001). The splenectomy group also lost more blood volume (P = 0.007) and had a higher postoperative complication rate (P = 0.005) than the ex situ group. Kaplan-Meier (log rank test) analysis showed significant survival differences among the three groups (P = 0.018). Multivariate analysis showed operation duration (P = 0.043), blood loss volume (P = 0.046), neoadjuvant chemotherapy (P = 0.005), and N stage (P < 0.001) were independent prognostic factors for survival. CONCLUSIONS: The ex situ procedure was more effective for SHLN dissection than the in situ procedure without sacrificing safety, whereas splenectomy was not more effective, and was less safe. The SHLN dissection method was not an independent risk factor for survival in this study. PMID- 27716193 TI - Keys to successful implementation of a French national quality indicator in health care organizations: a qualitative study. AB - BACKGROUND: Several countries have launched public reporting systems based on quality indicators (QIs) to increase transparency and improve quality in health care organizations (HCOs). However, a prerequisite to quality improvement is successful local QI implementation. The aim of this study was to explore the pathway through which a mandatory QI of the French national public reporting system, namely the quality of the anesthesia file (QAF), was put into practice. METHOD: Seven ethnographic case studies in French HCOs combining in situ observations and 37 semi-structured interviews. RESULTS: A significant proportion of potential QAF users, such as anesthetists or other health professionals were often unaware of quality data. They were, however, involved in improvement actions to meet the QAF criteria. In fact, three intertwined factors influenced QAF appropriation by anesthesia teams and impacted practice. The first factor was the action of clinical managers (chief anesthetists and head of department) who helped translate public policy into local practice largely by providing legitimacy by highlighting the scientific evidence underlying QAF, achieving consensus among team members, and pointing out the value of QAF as a means of work recognition. The two other factors related to the socio-material context, namely the coherence of information systems and the quality of interpersonal ties within the department. CONCLUSIONS: Public policy tends to focus on the metrological validity of QIs and on ranking methods and overlooks QI implementation. However, effective QI implementation depends on local managerial activity that is often invisible, in interaction with socio-material factors. When developing national quality improvement programs, health authorities might do well to specifically target these clinical managers who act as invaluable mediators. Their key role should be acknowledged and they ought to be provided with adequate resources. PMID- 27716192 TI - Sequence analysis of four vitamin D family genes (VDR, CYP24A1, CYP27B1 and CYP2R1) in Vogt-Koyanagi-Harada (VKH) patients: identification of a potentially pathogenic variant in CYP2R1. AB - BACKGROUND: VKH is a rare autoimmune disease. Decreased level of vitamin D has recently been found to be involved in the pathogenesis of Vogt-Koyanagi-Harada (VKH) disease. This study was designed to screen the vitamin D pathway genes for pathogenic mutations, if any, in VKH patients. METHODS: Genomic DNA was extracted from blood samples collected from patients with VKH disease and healthy controls. Entire coding region, exon-intron junctions of four genes were sequenced in DNA from 39 Saudi VKH patients and 50 ethnically matched healthy individuals. All patients and controls were unrelated. RESULTS: Vitamin D levels in VKH patients were found either insufficient (21-29 ng/mL) or deficient (<20 ng/mL). Sequencing analysis of the VDR, CYP24A1, CYP27B1 and CYP2R1 detected twelve nucleotide changes in these genes in our cohort of 39 patients; 4 of which were non-coding, 6 were synonymous coding and 2 were non-synonymous coding sequence changes. All synonymous coding variants were benign polymorphisms with no apparent clinical significance. A non-synonymous coding sequence variant (c.2 T > C; p.1Met?) found in VDR is an initiation coding change and was detected in control individuals as well, while another variant (c.852G > A; p.284 M > I) found in CYP2R1 is predicted to be disease causing by mutationtaster software. This potentially pathogenic variant was found in 17 out of 39 VKH patients. CONCLUSIONS: Screening of four Vitamin D pathway genes in 39 VKH patients shows that a potentially pathogenic sequence variant in CYP2R1 may cause VKH in a subset of patients. These findings support the previous observation that low vitamin D levels might play a role in VKH pathogenesis and mutations in genes involved in vitamin D anabolism and catabolism might be of importance in VKH pathobiology. PMID- 27716194 TI - Design of an orthopaedic-specific discharge summary. AB - BACKGROUND: Patients undergoing orthopaedic procedures experience major changes in function and daily routines upon their return home. Discharge summaries are an important communication tool that may play a role in optimizing a safe transition from hospital. Current care gaps and key elements of an ideal discharge summary specific for orthopaedic population are unknown. We sought to identify the challenges of current orthopaedic discharge summaries and to determine key elements of an ideal document. METHODS: Qualitative study survey using semi structured interviews with a sample of 17 patients and clinicians representing diverse professions, backgrounds, and practice settings. We used the constant comparative method of qualitative analysis to define the experiences and perceptions of quality gaps and strategies to improve orthopaedic-specific discharge summaries. RESULTS: We identified 3 major themes describing factors perceived to be limiting the quality of current discharge summaries: 1) physician centric documentation and the absence of a comprehensive, inter-professional perspective; 2) access to resources and health informatics; and 3) process variations in document creation and dissemination. CONCLUSIONS: Clinicians and patients identified several factors limiting the quality of discharge summaries among orthopaedic inpatients. Incorporating these elements could improve hospital transitions. PMID- 27716196 TI - Testing the construct validity of hospital care quality indicators: a case study on hip replacement. AB - BACKGROUND: Quality indicators are increasingly used to measure the quality of care and compare quality across hospitals. In the Netherlands over the past few years numerous hospital quality indicators have been developed and reported. Dutch indicators are mainly based on expert consensus and face validity and little is known about their construct validity. Therefore, we aim to study the construct validity of a set of national hospital quality indicators for hip replacements. METHODS: We used the scores of 100 Dutch hospitals on national hospital quality indicators looking at care delivered over a two year period. We assessed construct validity by relating structure, process and outcome indicators using chi-square statistics, bootstrapped Spearman correlations, and independent sample t-tests. We studied indicators that are expected to associate as they measure the same clinical construct. RESULT: Among the 28 hypothesized correlations, three associations were significant in the direction hypothesized. Hospitals with low scores on wound infections had high scores on scheduling postoperative appointments (p-value = 0.001) and high scores on not transfusing homologous blood (correlation coefficient = -0.28; p-value = 0.05). Hospitals with high scores on scheduling complication meetings, also had high scores on providing thrombosis prophylaxis (correlation coefficient = 0.21; p-value = 0.04). CONCLUSION: Despite the face validity of hospital quality indicators for hip replacement, construct validity seems to be limited. Although the individual indicators might be valid and actionable, drawing overall conclusions based on the whole indicator set should be done carefully, as construct validity could not be established. The factors that may explain the lack of construct validity are poor data quality, no adjustment for case-mix and statistical uncertainty. PMID- 27716195 TI - Sarcopenia in daily practice: assessment and management. AB - BACKGROUND: Sarcopenia is increasingly recognized as a correlate of ageing and is associated with increased likelihood of adverse outcomes including falls, fractures, frailty and mortality. Several tools have been recommended to assess muscle mass, muscle strength and physical performance in clinical trials. Whilst these tools have proven to be accurate and reliable in investigational settings, many are not easily applied to daily practice. METHODS: This paper is based on literature reviews performed by members of the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) working group on frailty and sarcopenia. Face-to-face meetings were afterwards organized for the whole group to make amendments and discuss further recommendations. RESULTS: This paper proposes some user-friendly and inexpensive methods that can be used to assess sarcopenia in real-life settings. Healthcare providers, particularly in primary care, should consider an assessment of sarcopenia in individuals at increased risk; suggested tools for assessing risk include the Red Flag Method, the SARC-F questionnaire, the SMI method or different prediction equations. Management of sarcopenia should primarily be patient centered and involve the combination of both resistance and endurance based activity programmes with or without dietary interventions. Development of a number of pharmacological interventions is also in progress. CONCLUSIONS: Assessment of sarcopenia in individuals with risk factors, symptoms and/or conditions exposing them to the risk of disability will become particularly important in the near future. PMID- 27716197 TI - Dietary intake patterns of children aged 6 years and their association with socioeconomic and demographic characteristics, early feeding practices and body mass index. AB - BACKGROUND: Dietary intake patterns of children from the 2004 Pelotas birth cohort study have been described at 12, 24 and 48 months of age, but there is no information about dietary patterns of these children at 6 years. Then, we aimed to identify and describe dietary intake patterns of children aged 6 years as well as to assess their association with socioeconomic and demographic characteristics, early feeding practices and BMI z-score at 6 years. METHODS: We used principal components analysis to identify dietary intake patterns of 3,427 children from the 2004 Pelotas (Brazil) birth cohort study. We used multiple linear regression models to evaluate whether socioeconomic and demographic characteristics (socioeconomic position, mother's age at birth, and child's sex and skin colour), early feeding practices (exclusive breastfeeding duration and age of introduction of complementary foods), and BMI z-score at 6 years were associated with dietary intake patterns. RESULTS: We identified seven dietary components of children's dietary intake patterns, namely: fruits and vegetables, snacks and treats, coffee and bread, milk, cheese and processed meats, rice and beans and carbohydrates. Dietary patterns were socially patterned, since six dietary components were associated with socioeconomic position. Moreover, high intake of snacks and treats and less fruits and vegetables were associated with children born to teenage mothers, with those exclusively breastfed for less than one month, and with those who started on complementary feeding before 4 months. Finally, overweight and obese children at 6 years presented lower intake of four out of seven dietary components, but we need to be cautious in interpretation due to limitations on food consumption reporting and due to possible reverse causality. CONCLUSION: Dietary intake patterns in children are strongly influenced by socioeconomic characteristics. Other factors such as younger maternal age at birth, and both early weaning and early introduction of complementary feeding appear to be related with 'unhealthier' patterns. Overweight and obese children presented lower intake of four out of seven dietary components, but further studies would be interesting to understand the longitudinal effect of children's feeding practices on BMI and adiposity. PMID- 27716198 TI - Identifying neuropsychiatric disorders in the Medicare Current Beneficiary Survey: the benefits of combining health survey and claims data. AB - BACKGROUND: To address the impact of using multiple sources of data in the United States Medicare Current Beneficiary Survey (MCBS) compared to using only one source of data to identify those with neuropsychiatric diagnoses. METHODS: Our data source was the 2010 MCBS with associated Medicare claims files (N = 14, 672 beneficiaries). The MCBS uses a stratified multistage probability sample design to select a nationally representative sample of Medicare beneficiaries. We excluded those participants in Medicare Health Maintenance Organizations (n = 3894) and performed a cross-sectional analysis. We classified neuropsychiatric conditions according to four broad categories: intellectual/developmental disorders, neurological conditions affecting the central nervous system (Neuro CNS), dementia, and psychiatric conditions. To account for different baseline prevalence differences of the categories we calculated the relative increase in prevalence that occurred from adding information from claims in addition to the absolute increase to allow comparison among categories. RESULTS: The estimated proportion of the sample with neuropsychiatric disorders increased to 50.0 (both sources) compared to 38.9 (health survey only) and 33.2 (claims only) with an overlap between sources of only 44.1 %. Augmenting health survey data with claims led to an increase in estimated percentage of intellectual/developmental disorders, psychiatric disorders, Neuro-CNS disorders and dementia of 1.3, 5.9, 11.5 and 3.8 respectively. In the community sample, the largest relative increases were seen for dementia (147.6 %) and Neuro-CNS disorders (87.4 %). With the exception of dementia, larger relative increases were seen in the facility sample with the greatest being for intellectual/developmental disorders (121.5 %) and Neuro-CNS disorders (93.8 %). CONCLUSIONS: The magnitude of potentially underestimated sample proportions using health survey only data varied strikingly according to the category of diagnosis and setting. Augmentation of survey data with claims appears essential particularly when attempting to estimate proportion of the sample affected by conditions that cause cognitive impairment which may affect ability to self-report. Augmenting proxy survey data with claims data also appears to be essential when ascertaining proportion of the facility-dwelling sample affected by neuropsychiatric disorders. PMID- 27716199 TI - PRognostic factor of Early Death In phase II Trials or the end of 'sufficient life expectancy' as an inclusion criterion? (PREDIT model). AB - BACKGROUND: Optimizing patient selection is a necessary step to design better clinical trials. 'Life expectancy' is a frequent inclusion criterion in phase II trial protocols, a measure that is subjective and often difficult to estimate. The aim of this study was to identify factors associated with early death in patients included in phase II studies. METHODS: We retrospectively collected medical records of patients with advanced solid tumors included in phase II trials in two French Comprehensive Cancer Centers (Bordeaux, Center 1 set; Lille, Center 2 set). We analyzed patients' baseline characteristics. Predictive factors associated with early death (mortality at 3 months) were identified by logistic regression. We built a model (PREDIT, PRognostic factor of Early Death In phase II Trials) based on prognostic factors isolated from the final multivariate model. RESULTS: Center 1 and 2 sets included 303 and 227 patients, respectively. Patients from Center 1 and 2 sets differed in tumor site, urological (26 % vs 15 %) and gastrointestinal (18 % vs 28 %) and in lung metastasis incidence (10 % vs 49 %). Overall survival (OS) at 3 months was 88 % (95 % CI [83.5; 91.0], Center 1 set) and 91 % (95 % CI [86.7; 94.2], Center 2 set). Presence of a 'life expectancy' inclusion criterion did not improve the 3-month OS (HR 0.6, 95 % CI [0.2; 1.2], p = 0.2325). Independent factors of early death were an ECOG score of 2 (OR 13.3, 95%CI [4.1; 43.4]), hyperleukocytosis (OR 5.5, 95 % CI [1.9; 16.3]) and anemia (OR 2.8, 95 % CI [1.1; 7.1]). Same predictive factors but with different association levels were found in the Center 2 set. Using the Center 1 set, ROC analysis shows a good discrimination to predict early death (AUC: 0.89 at 3 months and 0.86 at 6 months). CONCLUSIONS: Risk modeling in two independent cancer populations based on simple clinical parameters showed that baseline ECOG of 2, hyperleukocytosis and anemia are strong early-death predictive factors. This model allows identifying patients who may not benefit from a phase II trial investigational drug and may, therefore, represent a helpful tool to select patients for phase II trial entry. PMID- 27716200 TI - Implementing multifactorial psychotherapy research in online virtual environments (IMPROVE-2): study protocol for a phase III trial of the MOST randomized component selection method for internet cognitive-behavioural therapy for depression. AB - BACKGROUND: Depression is a global health challenge. Although there are effective psychological and pharmaceutical interventions, our best treatments achieve remission rates less than 1/3 and limited sustained recovery. Underpinning this efficacy gap is limited understanding of how complex psychological interventions for depression work. Recent reviews have argued that the active ingredients of therapy need to be identified so that therapy can be made briefer, more potent, and to improve scalability. This in turn requires the use of rigorous study designs that test the presence or absence of individual therapeutic elements, rather than standard comparative randomised controlled trials. One such approach is the Multiphase Optimization Strategy, which uses efficient experimentation such as factorial designs to identify active factors in complex interventions. This approach has been successfully applied to behavioural health but not yet to mental health interventions. METHODS/DESIGN: A Phase III randomised, single-blind balanced fractional factorial trial, based in England and conducted on the internet, randomized at the level of the patient, will investigate the active ingredients of internet cognitive-behavioural therapy (CBT) for depression. Adults with depression (operationalized as PHQ-9 score >= 10), recruited directly from the internet and from an UK National Health Service Improving Access to Psychological Therapies service, will be randomized across seven experimental factors, each reflecting the presence versus absence of specific treatment components (activity scheduling, functional analysis, thought challenging, relaxation, concreteness training, absorption, self-compassion training) using a 32-condition balanced fractional factorial design (2IV7-2). The primary outcome is symptoms of depression (PHQ-9) at 12 weeks. Secondary outcomes include symptoms of anxiety and process measures related to hypothesized mechanisms. DISCUSSION: Better understanding of the active ingredients of efficacious therapies, such as CBT, is necessary in order to improve and further disseminate these interventions. This study is the first application of a component selection experiment to psychological interventions in depression and will enable us to determine the main effect of each treatment component and its relative efficacy, and cast light on underlying mechanisms, so that we can systematically enhance internet CBT. TRIAL REGISTRATION: Current Controlled Trials ISRCTN24117387 . Registered 26 August 2014. PMID- 27716201 TI - Should all acutely ill children in primary care be tested with point-of-care CRP: a cluster randomised trial. AB - BACKGROUND: Point-of-care blood C-reactive protein (CRP) testing has diagnostic value in helping clinicians rule out the possibility of serious infection. We investigated whether it should be offered to all acutely ill children in primary care or restricted to those identified as at risk on clinical assessment. METHODS: Cluster randomised controlled trial involving acutely ill children presenting to 133 general practitioners (GPs) at 78 GP practices in Belgium. Practices were randomised to undertake point-of-care CRP testing in all children (1730 episodes) or restricted to children identified as at clinical risk (1417 episodes). Clinical risk was assessed by a validated clinical decision rule (presence of one of breathlessness, temperature >= 40 degrees C, diarrhoea and age 12-30 months, or clinician concern). The main trial outcome was hospital admission with serious infection within 5 days. No specific guidance was given to GPs on interpreting CRP levels but diagnostic performance is reported at 5, 20, 80 and 200 mg/L. RESULTS: Restricting CRP testing to those identified as at clinical risk substantially reduced the number of children tested by 79.9 % (95 % CI, 77.8-82.0 %). There was no significant difference between arms in the number of children with serious infection who were referred to hospital immediately (0.16 % vs. 0.14 %, P = 0.88). Only one child with a CRP < 5 mg/L had an illness requiring admission (a child with viral gastroenteritis admitted for rehydration). However, of the 80 children referred to hospital to rule out serious infection, 24 (30.7 %, 95 % CI, 19.6-45.6 %) had a CRP < 5 mg/L. CONCLUSIONS: CRP testing should be restricted to children at higher risk after clinical assessment. A CRP < 5 mg/L rules out serious infection and could be used by GPs to avoid unnecessary hospital referrals.

PMID- 27716202 TI - Proteomic analysis of the signaling pathway mediated by the heterotrimeric Galpha protein Pga1 of Penicillium chrysogenum. AB - BACKGROUND: The heterotrimeric Galpha protein Pga1-mediated signaling pathway regulates the entire developmental program in Penicillium chrysogenum, from spore germination to the formation of conidia. In addition it participates in the regulation of penicillin biosynthesis. We aimed to advance the understanding of this key signaling pathway using a proteomics approach, a powerful tool to identify effectors participating in signal transduction pathways. RESULTS: Penicillium chrysogenum mutants with different levels of activity of the Pga1 mediated signaling pathway were used to perform comparative proteomic analyses by 2D-DIGE and LC-MS/MS. Thirty proteins were identified which showed differences in abundance dependent on Pga1 activity level. By modifying the intracellular levels of cAMP we could establish cAMP-dependent and cAMP-independent pathways in Pga1 mediated signaling. Pga1 was shown to regulate abundance of enzymes in primary metabolic pathways involved in ATP, NADPH and cysteine biosynthesis, compounds that are needed for high levels of penicillin production. An in vivo phosphorylated protein containing a pleckstrin homology domain was identified; this protein is a candidate for signal transduction activity. Proteins with possible roles in purine metabolism, protein folding, stress response and morphogenesis were also identified whose abundance was regulated by Pga1 signaling. CONCLUSIONS: Thirty proteins whose abundance was regulated by the Pga1 mediated signaling pathway were identified. These proteins are involved in primary metabolism, stress response, development and signal transduction. A model describing the pathways through which Pga1 signaling regulates different cellular processes is proposed. PMID- 27716203 TI - Marital status, widowhood duration, gender and health outcomes: a cross-sectional study among older adults in India. AB - BACKGROUND: Previous research has demonstrated health benefits of marriage and the potential for worse outcomes during widowhood in some populations. However, few studies have assessed the relevance of widowhood and widowhood duration to a variety of health-related outcomes and chronic diseases among older adults in India, and even fewer have examined these relationships stratified by gender. METHODS: Using a cross-sectional representative sample of 9,615 adults aged 60 years or older from 7 states in diverse regions of India, we examine the relationship between widowhood and self-rated health, psychological distress, cognitive ability, and four chronic diseases before and after adjusting for demographic characteristics, socioeconomic status, living with children, and rural-urban location for men and women, separately. We then assess these associations when widowhood accounts for duration. RESULTS: Being widowed as opposed to married was associated with worse health outcomes for women after adjusting for other explanatory factors. Widowhood in general was not associated with any outcomes for men except for cognitive ability, though men who were widowed within 0-4 years were at greater risk for diabetes compared to married men. Moreover, recently widowed women and women who were widowed long-term were more likely to experience psychological distress, worse self-rated health, and hypertension, even after adjusting for other explanatory variables, whereas women widowed 5-9 years were not, compared to married women. CONCLUSIONS: Gender, the duration of widowhood, and type of outcome are each relevant pieces of information when assessing the potential for widowhood to negatively impact health. Future research should explore how the mechanisms linking widowhood to health vary over the course of widowhood. Incorporating information about marital relationships into the design of intervention programs may help better target potential beneficiaries among older adults in India. PMID- 27716205 TI - Effects of inhaled high-molecular weight hyaluronan in inflammatory airway disease. AB - Cystic fibrosis (CF) is a chronic inflammatory disease that is affecting thousands of patients worldwide. Adjuvant anti-inflammatory treatment is an important component of cystic fibrosis treatment, and has shown promise in preserving lung function and prolonging life expectancy. Inhaled high molecular weight hyaluronan (HMW-HA) is reported to improve tolerability of hypertonic saline and thus increase compliance, and has been approved in some European countries for use as an adjunct to hypertonic saline treatment in cystic fibrosis. However, there are theoretical concerns that HMW-HA breakdown products may be pro-inflammatory. In this clinical pilot study we show that sputum cytokines in CF patients receiving HMW-HA are not increased, and therefore HMW-HA does not appear to adversely affect inflammatory status in CF airways. PMID- 27716204 TI - Insulin-like growth factor 1 receptor mediated tyrosine 845 phosphorylation of epidermal growth factor receptor in the presence of monoclonal antibody cetuximab. AB - BACKGROUND: The epidermal growth factor receptor (EGFR) is frequently overexpressed in head and neck squamous cell carcinoma (HNSCC) and several other human cancers. Monoclonal antibodies, such as cetuximab that block EGFR signaling, have emerged as valuable molecular targeting agents in clinical cancer therapy. Prolonged exposure to cetuximab can result in cells acquiring resistance by a process that remains incompletely understood. METHODS: In this study, we analyzed the immediate early molecular response of cetuximab on physical interactions between EGFR and Insulin growth factor 1 like receptor (IGF-1R) in head and neck cancer cells that are resistant to cetuximab. Co immunoprecipitation, small molecule inhibitors against phospho-Src and IGF-1R, quantitative western blot of EGFR and Src phosphorylation, cell proliferation assays were used to suggest the role of IGF-1R mediated phosphorylation of specific tyrosine Y845 on EGFR via increased heterodimerization of EGFR and IGF 1R in cetuximab resistant cells. RESULTS: Heterodimerization of EGFR with IGF-1R was increased in cetuximab resistant HNSCC cell line UMSCC6. Basal levels of phosphorylated EGFR Y845 showed significant increase in the presence of cetuximab. Surprisingly, this activated Y845 level was not inhibited in the presence of Src inhibitor PP1. Instead, inhibition of IGF-1R by picropodophyllin (PPP) reduced the EGFR Y845 levels. Taken together, these results suggest that heterodimerization of EGFR with IGF-1R can lead to increased activity of EGFR and may be an important platform for cetuximab mediated signaling in head and neck tumors that have become resistant to anti-EGFR therapy. CONCLUSIONS: EGFR-IGF-1R interaction has a functional consequence of phosphorylation of EGFR Y845 in cetuximab resistant HNSCC cells and dual targeting of EGFR and IGF-1R is a promising therapeutic strategy. PMID- 27716206 TI - Association of serum calcium and heart failure with preserved ejection fraction in patients with type 2 diabetes. AB - BACKGROUND: Type 2 diabetes mellitus (T2DM) is a recognized trigger factor for heart failure with preserved ejection fraction (HFpEF). Recent studies show that higher serum calcium level is associated with greater risk of both T2DM and heart failure. We speculate that increased serum calcium is related to HFpEF prevalence in patients with T2DM. METHODS: In this cross-sectional echocardiographic study, 807 normocalcemia and normophosphatemia patients with T2DM participated, of whom 106 had HFpEF. Multinomial logistic regression was carried out to determine the variables associated with HFpEF. The associations between serum calcium and metabolic parameters, as well as the rate of HFpEF were examined using bivariate linear correlation and binary logistic regression, respectively. The predictive performance of serum calcium for HFpEF was evaluated using the area under the receiver operating characteristic curve (AUC). RESULTS: Patients with HFpEF have significantly higher serum calcium than those without HFpEF. Serum calcium was positively associated with total cholesterol, triglycerides, low-density lipoprotein cholesterol, serum uric acid, HOMA-IR and fasting plasma glucose. Compared with patients in the lowest serum calcium quartile, the odds ratio (OR) for HFpEF in patients in the highest quartile was 2.331 (95 % CI 1.088-4.994, p = 0.029). When calcium was analyzed as a continuous variable, per 1 mg/dL increase, the OR (95 % CI) for HFpEF was [2.712 (1.471-5.002), p = 0.001]. Serum calcium can predict HFpEF [AUC = 0.673, 95 % CI (0.620-0.726), p < 0.001]. CONCLUSIONS: An increase in serum calcium level is associated with an increased risk of HFpEF in patients with T2DM. PMID- 27716207 TI - A fast linear predictive adaptive model of packed bed coupled with UASB reactor treating onion waste to produce biofuel. AB - BACKGROUND: Agro-industrial wastes are an energy source for different industries. However, its application has not reached small industries. Previous and current research activities performed on the acidogenic phase of two-phase anaerobic digestion processes deal particularly with process optimization of the acid-phase reactors operating with a wide variety of substrates, both soluble and complex in nature. Mathematical models for anaerobic digestion have been developed to understand and improve the efficient operation of the process. At present, lineal models with the advantages of requiring less data, predicting future behavior and updating when a new set of data becomes available have been developed. The aim of this research was to contribute to the reduction of organic solid waste, generate biogas and develop a simple but accurate mathematical model to predict the behavior of the UASB reactor. RESULTS: The system was maintained separate for 14 days during which hydrolytic and acetogenic bacteria broke down onion waste, produced and accumulated volatile fatty acids. On this day, two reactors were coupled and the system continued for 16 days more. The biogas and methane yields and volatile solid reduction were 0.6 +/- 0.05 m3 (kg VSremoved)-1, 0.43 +/- 0.06 m3 (kg VSremoved)-1 and 83.5 +/- 9.8 %, respectively. The model application showed a good prediction of all process parameters defined; maximum error between experimental and predicted value was 1.84 % for alkalinity profile. CONCLUSIONS: A linear predictive adaptive model for anaerobic digestion of onion waste in a two-stage process was determined under batch-fed condition. Organic load rate (OLR) was maintained constant for the entire operation, modifying effluent hydrolysis reactor feed to UASB reactor. This condition avoids intoxication of UASB reactor and also limits external buffer addition. PMID- 27716208 TI - Service readiness, health facility management practices, and delivery care utilization in five states of Nigeria: a cross-sectional analysis. AB - BACKGROUND: Existing studies of delivery care in Nigeria have identified socioeconomic and cultural factors as the primary determinants of health facility delivery. However, no study has investigated the association between supply-side factors and health facility delivery. Our study analyzed the role of supply-side factors, particularly health facility readiness and management practices for provision of quality maternal health services. METHODS: Using linked data from the 2005 and 2009 health facility and household surveys in the five states in which the Community Participation for Action in the Social Sector (COMPASS) project was implemented, indices of health service readiness and management were developed based on World Health Organization guidelines. Multilevel logistic regression models were run to determine the association between these indices and health facility delivery among 2710 women aged 15-49 years whose last child was born within the five years preceding the surveys and who lived in 51 COMPASS LGAs. RESULTS: The health facility delivery rate increased from 25.4 % in 2005 to 44.1 % in 2009. Basic amenities for antenatal care provision, readiness to deliver basic emergency obstetric and newborn care, and management practices supportive of quality maternal health services were suboptimal in health facilities surveyed and did not change significantly between 2005 and 2009. The LGA mean index of basic amenities for antenatal care provision was more positively associated with the odds of health facility delivery in 2009 than in 2005, and in rural than in urban areas. The LGA mean index of management practices was associated with significantly lower odds of health facility delivery in rural than in urban areas. The LGA mean index of facility readiness to deliver basic emergency obstetric and neonatal care declined slightly from 5.16 in 2005 to 3.98 in 2009 and was unrelated to the odds of health facility delivery. CONCLUSION: Supply-side factors appeared to play a role in health facility delivery after controlling for socio-demographic factors. Improving uptake of delivery care would require greater attention to rural-urban inequities and health facility management practices, and to increasing the number of health facilities with fundamental elements for delivery of basic emergency obstetric and neonatal care. PMID- 27716209 TI - Effects of testosterone treatment on body fat and lean mass in obese men on a hypocaloric diet: a randomised controlled trial. AB - BACKGROUND: Whether testosterone treatment has benefits on body composition over and above caloric restriction in men is unknown. We hypothesised that testosterone treatment augments diet-induced loss of fat mass and prevents loss of muscle mass. METHODS: We conducted a randomised double-blind, parallel, placebo controlled trial at a tertiary referral centre. A total of 100 obese men (body mass index >= 30 kg/m2) with a total testosterone level of or below 12 nmol/L and a median age of 53 years (interquartile range 47-60) receiving 10 weeks of a very low energy diet (VLED) followed by 46 weeks of weight maintenance were randomly assigned at baseline to 56 weeks of 10-weekly intramuscular testosterone undecanoate (n = 49, cases) or matching placebo (n = 51, controls). The main outcome measures were the between-group difference in fat and lean mass by dual-energy X-ray absorptiometry, and visceral fat area (computed tomography). RESULTS: A total of 82 men completed the study. At study end, compared to controls, cases had greater reductions in fat mass, with a mean adjusted between group difference (MAD) of -2.9 kg (-5.7 to -0.2; P = 0.04), and in visceral fat (MAD -2678 mm2; -5180 to -176; P = 0.04). Although both groups lost the same lean mass following VLED (cases -3.9 kg (-5.3 to -2.6); controls -4.8 kg (-6.2 to 3.5), P = 0.36), cases regained lean mass (3.3 kg (1.9 to 4.7), P < 0.001) during weight maintenance, in contrast to controls (0.8 kg (-0.7 to 2.3), P = 0.29) so that, at study end, cases had an attenuated reduction in lean mass compared to controls (MAD 3.4 kg (1.3 to 5.5), P = 0.002). CONCLUSIONS: While dieting men receiving placebo lost both fat and lean mass, the weight loss with testosterone treatment was almost exclusively due to loss of body fat.

PMID- 27716210 TI - A cross-sectional study of physical activity and sedentary behaviours in a Caribbean population: combining objective and questionnaire data to guide future interventions. AB - BACKGROUND: Current understanding of population physical activity (PA) levels and sedentary behaviour in developing countries is limited, and based primarily on self-report. We described PA levels using objective and self-report methods in a developing country population. METHODS: PA was assessed in a cross-sectional, representative sample of the population of Barbados (25-54 years), using a validated questionnaire (RPAQ) and individually calibrated combined heart rate and movement sensing monitors. The RPAQ collects information on recalled activity in 4 domains: home, work, transport, and leisure. Physical inactivity was defined according to World Health Organization (WHO) guidelines; sedentary lifestyle was defined as being sedentary for 8 h or more daily; PA overestimation was defined as perceiving activity to be sufficient, when classified as 'inactive' by objective measurement. RESULTS: According to objective estimates, 90.5 % (95 % CI: 83.3,94.7) of women and 58.9 % (48.4,68.7) of men did not accumulate sufficient activity to meet WHO minimum recommendations. Overall, 50.7 % (43.3,58.1) of the population was sedentary for 8 h or more each day, and 60.1 % (52.8,66.9) overestimated their activity levels. The prevalence of inactivity was underestimated by self-report in both genders by 28 percentage points (95 % CI: 18,38), but the accuracy of reporting differed by age group, education level, occupational grade, and overweight/obesity status. Low PA was greater in more socially privileged groups: higher educational level and higher occupational grade were both associated with less objectively measured PA and more sedentary time. Variation in domain-specific self-reported physical activity energy expenditure (PAEE) by educational attainment was observed: higher education level was associated with more leisure activity and less occupational activity. Occupational PA was the main driver of PAEE for women and men according to self report, contributing 57 % (95 % CI: 52,61). The most popular leisure activities for both genders were walking and gardening. CONCLUSIONS: The use of both objective and self-report methods to assess PA and sedentary behaviour provides important complementary information to guide public health programmes. Our results emphasize the urgent need to increase PA and reduce sedentary time in this developing country population. Women and those with higher social economic position are particularly at risk from low levels of physical activity. PMID- 27716211 TI - A 19-SNP coronary heart disease gene score profile in subjects with type 2 diabetes: the coronary heart disease risk in type 2 diabetes (CoRDia study) study baseline characteristics. AB - BACKGROUND: The coronary risk in diabetes (CoRDia) trial (n = 211) compares the effectiveness of usual diabetes care with a self-management intervention (SMI), with and without personalised risk information (including genetics), on clinical and behavioural outcomes. Here we present an assessment of randomisation, the cardiac risk genotyping assay, and the genetic characteristics of the recruits. METHODS: Ten-year coronary heart disease (CHD) risk was calculated using the UKPDS score. Genetic CHD risk was determined by genotyping 19 single nucleotide polymorphisms (SNPs) using Randox's Cardiac Risk Prediction Array and calculating a gene score (GS). Accuracy of the array was assessed by genotyping a subset of pre-genotyped samples (n = 185). RESULTS: Overall, 10-year CHD risk ranged from 2 72 % but did not differ between the randomisation groups (p = 0.13). The array results were 99.8 % concordant with the pre-determined genotypes. The GS did not differ between the Caucasian participants in the CoRDia SMI plus risk group (n = 66) (p = 0.80) and a sample of UK healthy men (n = 1360). The GS was also associated with LDL-cholesterol (p = 0.05) and family history (p = 0.03) in a sample of UK healthy men (n = 1360). CONCLUSIONS: CHD risk is high in this group of T2D subjects. The risk array is an accurate genotyping assay, and is suitable for estimating an individual's genetic CHD risk.

PMID- 27716213 TI - Use of non-emergency contraceptive pills and concoctions as emergency contraception among Nigerian University students: results of a qualitative study. AB - BACKGROUND: Emergency contraception (EC) can significantly reduce the rate of unintended pregnancies and unsafe abortions especially in sub-Saharan Africa. Despite the increasing awareness of EC among educated young women in Nigeria, the rate of utilisation remains low. This study therefore explores the main barriers to the use of EC among female university students by analysing their knowledge of emergency contraception, methods ever used, perceived efficacy, and its acceptability. METHODS: This paper brings together the findings from several focus groups (N = 5) and in-depth interviews (N = 20) conducted amongst unmarried female undergraduate students in two Nigerian universities. RESULTS: Participants considered the use of condom and abstinence as the most effective methods of preventing unplanned pregnancy. However, many participants were misinformed about emergency contraception. Generally, participants relied on unconventional and unproven ECs; Ampiclox, "Alabukun", salt water solution, and lime and potash and perceived them to be effective in preventing unplanned pregnancies. Furthermore, respondents' narratives about methods of preventing unwanted pregnancies revealed that inadequate information on emergency contraception, reliance on unproven crude contraceptive methods, and misconception about modern contraception constitute barriers to the use of emergency contraception. CONCLUSIONS: The findings suggested that female university students are misinformed about emergency contraception and their reliance on unproven ECs constitutes a barrier to the use of approved EC methods. These barriers have serious implications for prevention of unplanned pregnancies in the cohort. Behavioural interventions targeting the use of unproven emergency contraceptive methods and misperceptions about ECs would be crucial for this cohort in Nigeria. PMID- 27716212 TI - Anti-inflammatory potential of PI3Kdelta and JAK inhibitors in asthma patients. AB - BACKGROUND: Phosphatidylinositol 3-kinase delta (PI3Kdelta) and Janus-activated kinases (JAK) are both novel anti-inflammatory targets in asthma that affect lymphocyte activation. We have investigated the anti-inflammatory effects of PI3Kdelta and JAK inhibition on cytokine release from asthma bronchoalveolar lavage (BAL) cells and T-cell activation, and measured lung PI3Kdelta and JAK signalling pathway expression. METHOD: Cells isolated from asthma patients and healthy subjects were treated with PI3Kdelta or JAK inhibitors, and/or dexamethasone, before T-cell receptor stimulation. Levels of IFNgamma, IL-13 and IL-17 were measured by ELISA and flow cytometry was used to assess T-cell activation. PI3Kdelta, PI3Kgamma, phosphorylated protein kinase B (pAKT) and Signal Transducer and Activator of Transcription (STAT) protein expression were assessed by immunohistochemistry in bronchial biopsy tissue from asthma patients and healthy subjects. PI3Kdelta expression in BAL CD3 cells was measured by flow cytometry. RESULTS: JAK and PI3Kdelta inhibitors reduced cytokine levels from both asthma and healthy BAL cells. Combining dexamethasone with either a JAK or PI3Kdelta inhibitor showed an additive anti-inflammatory effect. JAK and PI3Kdelta inhibitors were shown to have direct effects on T-cell activation. Immunohistochemistry showed increased numbers of PI3Kdelta expressing cells in asthma bronchial tissue compared to controls. Asthma CD3 cells in BAL expressed higher levels of PI3Kdelta protein compared to healthy cells. CONCLUSIONS: Targeting PI3Kdelta or JAK may prove effective in reducing T-cell activation and the resulting cytokine production in asthma. PMID- 27716214 TI - Administration of AMD3100 in endotoxemia is associated with pro-inflammatory, pro oxidative, and pro-apoptotic effects in vivo. AB - BACKGROUND: Chemokine receptor 4 (CXCR4) is a multifunctional G protein-coupled receptor that is activated by its natural ligand, C-X-C motif chemokine 12 (CXCL12). As a likely member of the lipopolysaccharide (LPS)-sensing complex, CXCR4 is involved in pro-inflammatory cytokine production and exhibits substantial chemo-attractive activity for various inflammatory cells. Here, we aimed to characterize the effects of CXCR4 blockade in systemic inflammation and to evaluate its impact on organ function. Furthermore, we investigated whether CXCR4 blockade exerts deleterious effects, thereby substantiating previous studies showing a beneficial outcome after treatment with CXCR4 agonists in endotoxemia. METHODS: The CXCR4 antagonist AMD3100 was administered intraperitoneally to mice shortly after LPS treatment. After 24 h, health status was determined and serum tumor necrosis factor alpha (TNF alpha), interferon gamma (IFN gamma), and nitric oxide (NO) levels were measured. We further assessed oxidative stress in the brain, kidney, and liver as well as liver biotransformation capacity. Finally, we utilized immunohistochemistry and immunoblotting in liver and spleen tissue to determine cluster of differentiation 3 (CD3), CD8, CD68, and TNF alpha expression patterns, and to assess the presence of various markers for apoptosis and oxidative stress. RESULTS: Mice treated with AMD3100 displayed impaired health status and showed enhanced serum levels of TNF alpha, IFN gamma and NO levels in endotoxemia. This compound also amplified LPS induced oxidative stress in all tissues investigated and decreased liver biotransformation capacity in co-treated animals. Co-treatment with AMD3100 further inhibited expression of nuclear factor (erythroid-derived 2)-like 2 (Nrf 2), heme oxygenase-1 (HO-1), and various cytochrome P450 enzymes, whereas it enhanced expression of CD3, inducible nitric oxide synthase, and TNF alpha, as well as the total number of neutrophils in liver tissue. Spleens from co-treated animals contained large numbers of erythrocytes and neutrophils, but fewer CD3+ cells, and demonstrated increased apoptosis in the white pulp. CONCLUSIONS: AMD3100 administration in a mouse model of endotoxemia further impaired health status and liver function and mediated pro-inflammatory, pro-oxidative, and pro apoptotic effects. This suggests that interruption of the CXCR4/CXCL12 axis is deleterious in acute inflammation and confirms previous findings showing beneficial effects of CXCR4 agonists in endotoxemia, thereby more clearly elucidating the role of CXCR4 in inflammation. PMID- 27716215 TI - Kinematic real-time feedback is more effective than traditional teaching method in learning ankle joint mobilisation: a randomised controlled trial. AB - BACKGROUND: To analyse the effect of real-time kinematic feedback (KRTF) when learning two ankle joint mobilisation techniques comparing the results with the traditional teaching method. METHODS: Double-blind randomized trial. SETTINGS: Faculty of Health Sciences. PARTICIPANTS: undergraduate students with no experience in manual therapy. Each student practised intensely for 90 min (45 min for each mobilisation) according to the random methodology assigned (G1: traditional method group and G2: KRTF group). G1: an expert professor supervising the student's practice, the professorstudent ratio was 1:8. G2: placed in front of a station where, while they performed the manoeuvre, they received a KRTF on a laptop. OUTCOME MEASURES: total time of mobilisation, time to reach maximum amplitude, maximum angular displacement in the three axes, maximum and average velocity to reach the maximum angular displacement, average velocity during the mobilisation. RESULTS: Among the pre-post intervention measurements, there were significant differences within the two groups for all outcome variables, however, G2 (KRTF) achieved significantly greater improvements in kinematic parameters for the two mobilisations (significant increase in displacement, velocity and significant reduction in the mobilisations runtime) than G1. Ankle plantar flexion: G1's measurement stability (post-intervention) ranged between 0.491 and 0.687, while G2's measurement stability ranged between 0.899 and 0.984. Ankle dorsal flexion mobilisation: G1 the measurement stability (post-intervention) ranged from 0.543 and 0.684 while G2 ranged between 0.899 and 0.974. CONCLUSION: KRTF was proven to be more effective tool than traditional teaching method in the teaching - learning process of two joint mobilisation techniques. TRIAL REGISTRATION: NCT02504710. PMID- 27716216 TI - The Anatomy to Genomics (ATG) Start Genetics medical school initiative: incorporating exome sequencing data from cadavers used for Anatomy instruction into the first year curriculum. AB - BACKGROUND: The increasing use of next generation DNA sequencing in clinical medicine is exposing the need for more genetics education in physician training. We piloted an initiative to determine the feasibility of incorporating exome sequencing data generated from DNA obtained from cadavers used for teaching Anatomy into a first year medical student integrated block-style course. METHODS: We optimized the procedure to obtain DNA for exome sequencing by comparing the quality and quantity of DNA isolated from several tissues by two different extraction methods. DNA was sequenced using exome capture and analyzed using standard methods. Single nucleotide variants (SNVs), as well as small insertions/deletions, with potential functional impact were selected by faculty for student teams to independently investigate and prepare presentations on their findings. RESULTS: A total of seven cadaver DNAs were sequenced yielding high quality results. SNVs were identified that were associated, with known physical traits and disease susceptibility, as well as pharmacogenomic phenotypes. Students presented findings based on correlation with known clinical information about the cadavers' diseases and traits. CONCLUSION: Exome sequencing of cadaver DNA is a useful tool to integrate Anatomy with Genetics and Biochemistry into a first year medical student core curriculum. PMID- 27716217 TI - Ultrasound-guided gastrocnemius recession: a new ultra-minimally invasive surgical technique. AB - BACKGROUND: Isolated gastrocnemius contracture is thought to lead to numerous conditions. Although many techniques have been described for gastrocnemius recession, potential anesthetic, cosmetic, and wound-related complications can lead to patient dissatisfaction. Open and endoscopic recession techniques require epidural anesthesia, lower limb ischemia, and stitches and may lead to damage of the sural nerve, which is not under the complete control of the surgeon at all stages of the procedure. The purpose of this study was to evaluate the safety and efficacy of a new technique based on ultrasound-guided ultra-minimally invasive gastrocnemius recession. METHODS: We performed a pilot study with 22 cadavers to ensure that the technique was effective and safe. In the second phase, we prospectively performed gastrocnemius recession in 23 patients (25 cases) with chronic non-insertional Achilles tendinopathy, equinus foot, and other indications. In the clinical study, we evaluated the range of dorsiflexion before and after the procedure, clinical outcomes with VAS and AOFAS scores, and potential complications, including neurovascular injuries. RESULTS: We achieved complete release of the gastrocnemius tendon in all cases in the cadaveric study, with no damage to the sural nerve or vessels and minimal damage to the underlying muscle fibers. Ankle dorsiflexion increased for every patient in the study (mean, 14 degrees ; standard deviation, 3 degrees ) and was maintained throughout follow up. The mean preoperative VAS score was 7 (6-9), which improved to 0 (0-1). The AOFAS Ankle-Hindfoot Score improved from a mean of 30 (20-40) to 93 (85-100) at 6 months. No major complications were observed. All patients returned to their previous sports after 6 months. CONCLUSIONS: After cadaveric and clinical study, we considered the technique to be safe and effective to perform ultrasound-guided ultra-minimally invasive gastrocnemius recession using a 1-mm incision in vivo. This novel technique represents an alternative to open techniques, with encouraging results and with the advantages of reducing pain, obviating lower limb ischemia, deeper anaesthesia, thus decreasing complications and contraindications and accelerating recovery. PMID- 27716218 TI - Effectiveness of community-based football compared to usual care in men with prostate cancer: Protocol for a randomised, controlled, parallel group, multicenter superiority trial (The FC Prostate Community Trial). AB - BACKGROUND: Prostate cancer is the most common non-cutaneous malignancy in men. Today most patients may expect to live years following the diagnosis and may thus experience significant morbidity due to disease progression and treatment toxicity. In order to address some of these problems exercise has been suggested and previously studies have shown improvements of disease specific quality of life and a reduction in treatment-related toxicity. Cohort studies with long term follow up have suggested that physical activity is associated with improved survival in prostate cancer patients. Previously one randomised controlled trial has examined the efficacy of football in prostate cancer patients undergoing androgen deprivation therapy to usual care and reported positive effects on lean body mass and bone markers. Against this background, we wish to examine the effectiveness of community-based football for men diagnosed with prostate cancer. METHODS: Using a randomised controlled parallel group, multicenter, superiority trial design, two hundred prostate cancer patients will be recruited and randomised (1:1) to either community-based football one hour twice weekly or to a control group. The intervention period will be six months. The primary outcome is quality of life assessed after 12 weeks based on the change from baseline in the Functional Assessment of Cancer Therapy-Prostate questionnaire. Secondary outcomes are change from baseline to six months in quality of life, lean body mass, fat mass, whole body and regional bone markers, as well as physical activity and functional capacity at 12 weeks and six months. Safety outcome variables will be falls resulting in seeking medical assessment and fractures during the six-month period. DISCUSSION: Football is viewed as a case for non professional, supervised community-based team sport for promoting long-term physical activity in men diagnosed with prostate cancer. This randomised trial will provide data on effectiveness and safety for men with prostate cancer when football training is delivered in local football clubs.

PMID- 27716219 TI - Effect of psycho-educational interventions on quality of life in patients with implantable cardioverter defibrillators: a meta-analysis of randomized controlled trials. AB - BACKGROUND: Implantable cardioverter defibrillators (ICD) were developed for primary and secondary prevention of sudden cardiac death. However, ICD recipients' mortality is significantly predicted by their quality of life (QOL). The aim of this meta-analysis was to evaluate the effects of psycho-educational interventions on QOL in patients with ICDs. METHODS: We systematically searched PubMed, Medline, Cochrane Library, and CINAHL through April 2015 and references of relevant articles. Studies were reviewed if they met following criteria: (1) randomized controlled trial, (2) participants were adults with an ICD, and (3) data were sufficient to evaluate the effect of psychological or educational interventions on QOL measured by the SF-36 or SF-12. Studies were independently selected and their data were extracted by two reviewers. Study quality was evaluated using a modified Jadad scale. The meta-analysis was conducted using the Cochrane Collaboration's Review Manager Software Package (RevMan 5). Study heterogeneity was assessed by Q statistics and I 2 statistic. Depending on heterogeneity, data were pooled across trials using fixed-effect or random-effect modeling. RESULTS: Seven randomized controlled trials fulfilled the inclusion and exclusion criteria, and included 1017 participants. The psycho-educational interventions improved physical component summary (PCS) scores in the intervention groups more than in control groups (mean difference 2.08, 95 % CI 0.86 to 3.29, p < 0.001), but did not significantly affect mental component summary (MCS) scores (mean difference 0.84, 95 % CI -1.68 to 3.35, p = 0.52). CONCLUSION: Our meta-analysis demonstrates that psycho-educational interventions improved the physical component, but not the mental component of QOL in patients with ICDs. PMID- 27716220 TI - The APOA5 rs662799 polymorphism is associated with dyslipidemia and the severity of coronary heart disease in Chinese women. AB - BACKGROUND: The APOA5 rs662799 polymorphism has been widely reported regarding its associations with the plasma lipid levels and the occurrence of coronary heart disease (CHD), whereas its relationship with the severity of CHD has not yet been explored. METHODS: Four hundred and seventy-eight angiografically defined subjects (325 CHD patients and 153 CHD-free controls) were enrolled in this study. The rs662799 polymorphism was genotyped, and the fasting lipid data were collected for all participants. The severity of CHD was evaluated for the CHD patients by using Gensini scores. RESULTS: The variant C allele of the rs662799 polymorphism was associated with lower levels of HDL-C in CHD-free women, and higher levels of TG and TG/HDL-C in women with CHD (P < 0.05 for all). The C allele was associated with higher prevalence of dyslipidemia and higher levels of Gensini scores only in women (P < 0.05 for both), but not in men. Multivariate linear regression analysis showed that the rs662799 polymorphism was independently associated with the Gensini scores in women after adjustment for other potential CHD risk factors (Beta = 0.157, 95 % CI: 0.017-0.298, P = 0.028). CONCLUSION: Our data indicate that the rs662799 polymorphism is associated with dyslipidemia and the severity of CHD in Chinese women. PMID- 27716221 TI - Self-management of musculoskeletal hand pain and hand problems in community dwelling adults aged 50 years and older: results from a cross-sectional study in a UK population. AB - BACKGROUND: Musculoskeletal pain is common in adults, with the hand being frequently affected. Healthcare services have the potential to be of benefit to adults with hand pain and problems, through promotion and facilitation of self management. METHODS: This paper explores existing self-management in a UK population of community-dwelling adults aged 50 years and over using data from surveys and a nested clinical cohort study. Self-management of hand problems was considered in three ways: self-directed treatment approaches used, adaptation behaviours adopted and choice to consult with a healthcare professional. RESULTS: The treatment approaches most commonly used were 'exercise/movement' (n = 151, 69 %) and 'resting' the hands (n = 139, 69 %). The use of adaptation behaviour was widespread: 217 (99 %) people reported using one or more adaptation behaviours. Under half of survey respondents who reported hand pain (n = 783, 43 %) had consulted a healthcare professional about their problem during the last year: the lowest rate of consultation was for occupational therapy (n = 60, 3 %). CONCLUSIONS: Self-directed treatment and adaptation behaviours were widespread in adults aged 50 years and over with hand problems, but consultation with a healthcare professional was low. PMID- 27716222 TI - Complicated norovirus infection and assessment of severity by a modified Vesikari disease score system in hospitalized children. AB - BACKGROUND: Norovirus (NoV) GII.4 is the most common genotype for norovirus gastroenteritis worldwide. New variants or subgenotypes are continuously emerging, thus posing a serious threat to child health. METHODS: We compared retrospectively the clinical manifestations and complications of norovirus gastroenteritis in children from April, 2004 through December, 2012. NoV variants were analyzed to investigate the association of circulating viral strains with the complications. A modified disease severity score system based on Vesikari score system was devised and to evaluate disease severity. RESULTS: Compared to the outbreak in 2004/2005 winter, significant higher incidence of complications in the later periods are: convulsive disorder (p < 0.001) in 2006/2007 winter gastrointestinal hemorrhage (p = 0.047) and severe abdominal pain or irritability (p = 0.033) in 2008/09/10 winter; gastrointestinal hemorrhage (p = 0.030), severe abdominal pain or irritability (p = 0.014), and prominent hyperthermia (fever >39 degrees C, p = 0.001) in 2011/2012 winter. GII.4 Den_Haag_2006b, GII.4 2010, GII.4 Sydney 2012, and GII.4 2012b were the predominant strains in the outbreaks after 2006. By the modified severity score system, severe norovirus disease occurred in 28.5 %, 32 %, 33.3 %, and 30.2 % of the patients in the four periods. A longer duration of hospitalization (p = 0.02) were found in those with high score irrespective of the year of admission. CONCLUSIONS: Our study demonstrated NoV outbreaks in northern Taiwan caused by different GII.4 variants that were associated with specific complications and uncommon clinical presentations. A modified severity score system first proposed in this study was able to identify severe cases with a longer hospital stay in NoV-infected children. PMID- 27716223 TI - Gender difference and effect of pharmacotherapy: findings from a smoking cessation service. AB - BACKGROUND: Smoking cessation services are available in England to provide assistance to those wishing to quit smoking. Data from one such service were analysed in order to investigate differences in quit rate between males and females prescribed with different treatments. METHODS: A logistic regression model was fitted to the data using the binary response of self-reported quit (failed attempt = 0, successful attempt = 1), validated by Carbon Monoxide (CO) monitoring, 4 weeks after commencing programme. Main effects fitted were: client gender; age; region; the type of advisory sessions; and pharmacotherapy, Nicotine Replacement Therapy (NRT) or Varenicline. A second model was fitted including all main effects plus two-way interactions except region. These models were repeated using 12-week self-reported quit as the outcome. RESULTS: At 4 weeks, all main effects were statistically significant, with males more likely (odds ratio and 95 % CI, females v males = 0.88 [0.79-0.97]), older smokers more likely (adjusted odds ratios [OR] and 95 % confidence interval [CI] respectively for groups 20-29, 30-49, 50-69 and 70+ vs 12-19 age group: 1.79 [1.39-2.31], 2.12 [1.68-2.68], 2.30 [1.80-2.92] and 2.47 [1.81-3.37] and for overall difference between groups, chi2(4) = 53.5, p < 0.001) and clients being treated with Varenicline more likely to have successfully quit than those on NRT (adjusted OR and 95 % CI for Varenicline vs NRT = 1.41 [1.21-1.64]). Statistically significant interactions were observed between (i) gender and type of counselling, and (ii) age and type of counselling. Similar results were seen in relation to main effects at 12 weeks except that type of counselling was non-significant. The only significant interaction at this stage was between gender and pharmacotherapy (adjusted OR and 95 % CI for females using Varenicline versus all other groups = 1.43 [1.06 1.94]). CONCLUSION: Gender and treatment options were identified as predictors of abstinence at both 4 and 12 weeks after quitting smoking. Furthermore, interactions were observed between gender and (i) type of counselling received (ii) pharmacotherapy. In particular, the quit rate in women at 12 weeks was significantly improved in conjunction with Varenicline use. These findings have implications for service delivery. PMID- 27716224 TI - Factors associated with acceptability of child circumcision in Botswana -- a cross sectional survey. AB - BACKGROUND: Safe male child circumcision has been recently adopted as a potential strategy to prevent HIV/AIDS transmission in later life in Botswana. METHODS: Data used was derived from a cross-sectional survey, the Botswana AIDS Impact Survey (BAIS) IV, conducted in 2013. A total sample of 7984 respondents in ages 15-64 years who had successfully completed the individual questionnaire during the survey were selected and included for analysis. Both descriptive and multivariable analyses were used to explore factors associated with acceptability of child circumcision. Data was analysed using SPSS version 22 program. RESULTS: Results indicate that about 84 % of participants said they would circumcise their male children aged 18 years and below, while 93 % were aware of the safe male circumcision program. Bivariate analyses results show that acceptability of child circumcision was significantly associated with sex, age, education, religion, residence, HIV status of the parent, fathers circumcision status, father's intention to circumcise and parent's knowledge about the safe male circumcision program. Multivariable analyses results indicate positive association between respondent's HIV positive status (OR, 3.5), Men's circumcision status (OR, 3.7), men's intention to circumcise (OR, 9.3) and acceptability of child circumcision. CONCLUSION: Results of this study indicate some relatively high acceptability levels for child circumcision. Some individual behavioural factors influencing acceptability of child circumcision were also identified. This study provides a proper understanding of factors associated with acceptability of child circumcision which will ultimately enhance the successful roll-out of the school going children circumcision program in Botswana. PMID- 27716225 TI - Functional inclusion bodies produced in the yeast Pichia pastoris. AB - BACKGROUND: Bacterial inclusion bodies (IBs) are non-toxic protein aggregates commonly produced in recombinant bacteria. They are formed by a mixture of highly stable amyloid-like fibrils and releasable protein species with a significant extent of secondary structure, and are often functional. As nano structured materials, they are gaining biomedical interest because of the combination of submicron size, mechanical stability and biological activity, together with their ability to interact with mammalian cell membranes for subsequent cell penetration in absence of toxicity. Since essentially any protein species can be obtained as IBs, these entities, as well as related protein clusters (e.g., aggresomes), are being explored in biocatalysis and in biomedicine as mechanically stable sources of functional protein. One of the major bottlenecks for uses of IBs in biological interfaces is their potential contamination with endotoxins from producing bacteria. RESULTS: To overcome this hurdle, we have explored here the controlled production of functional IBs in the yeast Pichia pastoris (Komagataella spp.), an endotoxin-free host system for recombinant protein production, and determined the main physicochemical and biological traits of these materials. Quantitative and qualitative approaches clearly indicate the formation of IBs inside yeast, similar in morphology, size and biological activity to those produced in E. coli, that once purified, interact with mammalian cell membranes and penetrate cultured mammalian cells in absence of toxicity. CONCLUSIONS: Structurally and functionally similar from those produced in E. coli, the controlled production of IBs in P. pastoris demonstrates that yeasts can be used as convenient platforms for the biological fabrication of self-organizing protein materials in absence of potential endotoxin contamination and with additional advantages regarding, among others, post-translational modifications often required for protein functionality. PMID- 27716227 TI - Modified mallampati classification in determining the success of unsedated transesophageal echocardiography procedure in patients with heart disease: simple but efficient. AB - BACKGROUND: The transesophageal echocardiograhpy (TEE) has been studied worldwide. However, identifying additional factors on top of operator's experience and patient's cooperation which could influence the success of the procedure in unsedated patients with heart disease is not well documented. METHODS: Under the cross-sectional descriptive design, 85 target patients were fulfilling the criteria: being Thai national at the age of at least 20-year-old, being performed TEE by the study participant's cardiologists, being able to communicate verbally. Seven outcomes were recorded, including gag reflex, insertion attempt, insertion time, vital signs (heart rate, oxygen saturation and mean arterial blood pressure), visible blood on TEE probe tip, and oropharyngeal pain at 1 h and 24-h. RESULTS: There were 85 eligible patients during June 2013 to June 2014 [corrected]. The major participants were male (46, 54 %) and the mean age was 51.2 +/- 12.5 years. The MMC class III was mostly found (33, 38.80 %). TEE probe insertion time and gag reflex were indicated statistical significance (P < 0.05). Linear regression revealed that MMC class III (b 3.718; SD +/- 1.077; P = 0.001) and class IV (b 5.15; SD +/- 1.286; P = 0.000) were statistically associated with TEE probe insertion time, whereas MMC class II was no statistically significant (b 2.348; SD +/- 1.405; P = 0.099) according to constant value in MMC class I (5.318 s). Similarly, logistic regression indicated that the patients with high grade MMC were more likely to have gagging than the low grade MMC patients (MMC 2 OR 0.567, 95 % CI 0.09-3.42, P = 0.536; MMC 3 OR 5.231, 95 % CI 1.55-17.67, P = 0.008; MMC 4 OR 3.4, 95 % CI 0.84-13.76, P = 0.086). CONCLUSIONS: Modified Mallampati Classification is one of determining factors in the success of unsedated TEE procedure in patients with heart disease, especially for assessment of gagging and successful TEE probe insertion time. PMID- 27716226 TI - A pilot cluster randomised controlled trial of a support and training intervention to improve the mental health of secondary school teachers and students - the WISE (Wellbeing in Secondary Education) study. AB - BACKGROUND: Secondary school teachers are at heightened risk of psychological distress, which can lead to poor work performance, poor quality teacher-student relationships and mental illness. A pilot cluster randomised controlled trial (RCT) - the WISE study - evaluated the feasibility of a full-scale RCT of an intervention to support school staff's own mental health, and train them in supporting student mental health. METHODS: Six schools were randomised to an intervention or control group. In the intervention schools i) 8-9 staff received Mental Health First Aid (MHFA) training and became staff peer supporters, and ii) youth MHFA training was offered to the wider staff body. Control schools continued with usual practice. We used thematic qualitative data analysis and regression modelling to ascertain the feasibility, acceptability and potential usefulness of the intervention. RESULTS: Thirteen training observations, 14 staff focus groups and 6 staff interviews were completed, and 438 staff (43.5 %) and 1,862 (56.3 %) students (years 8 and 9) completed questionnaires at baseline and one year later. MHFA training was considered relevant for schools, and trainees gained in knowledge, confidence in helping others, and awareness regarding their own mental health. Suggestions for reducing the length of the training and focusing on helping strategies were made. A peer support service was established in all intervention schools and was perceived to be helpful in supporting individuals in difficulty - for example through listening, and signposting to other services - and raising the profile of mental health at a whole school level. Barriers to use included lack of knowledge about the service, concerns about confidentiality and a preference for accessing support from pre-existing networks. CONCLUSIONS: The WISE intervention is feasible and acceptable to schools. Results support the development of a full-scale cluster RCT, if steps are taken to improve response rates and implement the suggested improvements to the intervention.

PMID- 27716228 TI - Measuring the impact of migraine for evaluating outcomes of preventive treatments for migraine headaches. AB - BACKGROUND: Migraine is characterized by headache with symptoms such as intense pain, nausea, vomiting, photophobia, and phonophobia that significantly impact individuals' lives. The objective of this study was to develop a strategy to measure outcomes from the patients' perspectives for use in evaluating preventive treatments for migraine. METHODS: This study used a multi-stage process. The first stage included concept identification research through literature review, patient-reported outcome (PRO) instrument content review, and clinician interviews, and resulted in a list of concepts relevant to understand the migraine experience. These results informed the design of the subsequent concept elicitation stage that involved qualitative interviews of adults with migraine to understand their experiences. Information from these two stages was used to develop a conceptual disease model (CDM) of the migraine experience. This CDM was used to identify concepts of interest (COI) to evaluate patient-relevant outcomes for assessing treatment benefit of migraine prophylactics. In the final stage, existing PRO instruments were reviewed to assess coverage of concepts related to the selected COI. RESULTS: Nine articles from 563 screened abstracts underwent full review to identify migraine-relevant concepts. This concept identification and subsequent concept elicitation interviews (N = 32; 21 episodic migraine; 11 chronic migraine) indicated that people with migraine experience difficulties during and between migraine attacks with considerable day-to-day variability in the impact on movement, ability to perform every day and social activities, and emotion. The CDM organized concepts as proximal to and more distal from disease defining migraine symptoms, and was used to identify impact on physical function as the key COI. The item level review of PRO instruments revealed that none of the existing PRO instruments were suitable to collect data on impact of migraine on physical functioning, to evaluate treatment benefit. CONCLUSIONS: The impact of migraine includes impairments in functioning during and between migraine attacks that vary considerably on a daily basis. There is a need for novel PRO instruments that reflect patients' migraine experience to assess treatment benefit of migraine prophylactics. These instruments must evaluate the concepts identified and be able to capture the variability of patients' experience. PMID- 27716229 TI - Particulate-steroid betamethasone added to ropivacaine in interscalene brachial plexus block for arthroscopic rotator cuff repair improves postoperative analgesia. AB - BACKGROUND: Dexamethasone added to local anesthetic for brachial plexus block improves postoperative pain after arthroscopic rotator cuff repair, as compared with the use of local anesthetic alone. Dexamethasone is present in non particulate form in local anesthetic solution, while betamethasone is partially present in particulate form. The particulate betamethasone gradually decays and is expected to cause its longer-lasting effect. This study investigated the postoperative analgesic effect of betamethasone added to ropivacaine for brachial plexus block in patients who underwent arthroscopic rotator cuff repair. METHODS: This was a prospective, randomized, triple-blind study of 44 patients undergoing arthroscopic rotator cuff repair surgery. Ultrasound-guided interscalene brachial plexus block, involving 20 mL of 0.375 % ropivacaine (group R) or 19 mL of 0.375 % ropivacaine with 4 mg (1 mL) of betamethasone (group BR), was administered and surgery was performed under general anesthesia. After surgery, the pain score was recorded at 12 h after surgery, and on the first, second, and seventh postoperative day. Analgesia duration, offset time of motor block, frequency of rescue analgesic administration, postoperative nausea/vomiting, and sleep disturbance during the night after surgery were recorded. The numerical values were expressed as median [interquartile range]. P values < 0.05 were considered statistically significant. RESULTS: The duration of analgesia was significantly prolonged in group BR (group BR: 19.1 h [16.6, 20.9 h], group R: 13.3 h [11.6, 16.5 h], p < 0.001). The pain scores at 12 h after surgery and on the first and seventh day after surgery were significantly lower in group BR than in group R. The duration of motor block was significantly prolonged in group BR. The frequency of rescue analgesic administration and the sleep disturbance rate were significantly lower in group BR. There was no difference in postoperative nausea/vomiting between the two groups. CONCLUSIONS: Betamethasone added to local anesthetic in interscalene brachial plexus block improved postoperative pain after arthroscopic rotator cuff repair, and betamethasone prolonged the duration of analgesia by almost 6 h.

PMID- 27716230 TI - Building capacity for knowledge translation in occupational therapy: learning through participatory action research. AB - BACKGROUND: There has been widespread acknowledgement of the need to build capacity in knowledge translation however much of the existing work focuses on building capacity amongst researchers rather than with clinicians directly. This paper's aim is to describe a research project for developing a knowledge translation capacity building program for occupational therapy clinicians. METHODS: Participatory action research methods were used to both develop and evaluate the knowledge translation capacity-building program. Participants were occupational therapists from a large metropolitan hospital in Australia. Researchers and clinicians worked together to use the action cycle of the Knowledge to Action Framework to increase use of knowledge translation itself within the department in general, within their clinical teams, and to facilitate knowledge translation becoming part of the department's culture. Barriers and enablers to using knowledge translation were identified through a survey based on the Theoretical Domains Framework and through focus groups. Multiple interventions were used to develop a knowledge translation capacity-building program. RESULTS: Fifty-two occupational therapists participated initially, but only 20 across the first 18 months of the project. Barriers and enablers were identified across all domains of the Theoretical Domains Framework. Interventions selected to address these barriers or facilitate enablers were categorised into ten different categories: educational outreach; teams working on clinical knowledge translation case studies; identifying time blocks for knowledge translation; mentoring; leadership strategies; communication strategies; documentation and resources to support knowledge translation; funding a knowledge translation champion one day per week; setting goals for knowledge translation; and knowledge translation reporting strategies. Use of these strategies was, and continues to be monitored. Participants continue to be actively involved in learning and shaping the knowledge translation program across the department and within their specific clinical areas. CONCLUSION: To build capacity for knowledge translation, it is important to involve clinicians. The action cycle of the Knowledge to Action framework is a useful guide to introduce the knowledge translation process to clinicians. It may be used to engage the department as a whole, and facilitate the learning and application of knowledge translation within specific clinical areas. Research evaluating this knowledge translation program is being conducted. PMID- 27716231 TI - Display of a beta-mannanase and a chitosanase on the cell surface of Lactobacillus plantarum towards the development of whole-cell biocatalysts. AB - BACKGROUND: Lactobacillus plantarum is considered as a potential cell factory because of its GRAS (generally recognized as safe) status and long history of use in food applications. Its possible applications include in situ delivery of proteins to a host, based on its ability to persist at mucosal surfaces of the human intestine, and the production of food-related enzymes. By displaying different enzymes on the surface of L. plantarum cells these could be used as whole-cell biocatalysts for the production of oligosaccharides. In this present study, we aimed to express and display a mannanase and a chitosanase on the cell surface of L. plantarum. RESULTS: ManB, a mannanase from Bacillus licheniformis DSM13, and CsnA, a chitosanase from Bacillus subtilis ATCC 23857 were fused to different anchoring motifs of L. plantarum for covalent attachment to the cell surface, either via an N-terminal lipoprotein anchor (Lp_1261) or a C-terminal cell wall anchor (Lp_2578), and the resulting fusion proteins were expressed in L. plantarum WCFS1. The localization of the recombinant proteins on the bacterial cell surface was confirmed by flow cytometry and immunofluorescence microscopy. The highest mannanase and chitosanase activities obtained for displaying L. plantarum cells were 890 U and 1360 U g dry cell weight, respectively. In reactions with chitosan and galactomannans, L. plantarum CsnA- and ManB displaying cells produced chito- and manno-oligosaccharides, respectively, as analyzed by high performance anion exchange chromatography (HPAEC) and mass spectrometry (MS). Surface-displayed ManB is able to break down galactomannan (LBG) into smaller manno-oligosaccharides, which can support growth of L. plantarum. CONCLUSION: This study shows that mannanolytic and chitinolytic enzymes can be anchored to the cell surface of L. plantarum in active forms. L. plantarum chitosanase- and mannanase-displaying cells should be of interest for the production of potentially 'prebiotic' oligosaccharides. This approach, with the enzyme of interest being displayed on the cell surface of a food-grade organism, may also be applied in production processes relevant for food industry. PMID- 27716232 TI - The role of expression imbalance between adipose synthesis and storage mediated by PPAR-gamma/FSP27 in the formation of insulin resistance in catch up growth. AB - BACKGROUND: Catch up growth (CUG) motivated by under-nutrition can lead to insulin resistance (IR) and visceral fat over-accumulation. However, the precise mechanisms on IR induced by adipose tissue changes during CUG remain unresolved. METHODS: Experimental rats were divided into three groups: normal chow group, catch up growth group and resveratrol administrated group. The whole experiment was carried out in four stages: 4, 6, 8 and 12 weeks. Peroxisome-proliferator activated receptor gamma (PPAR-gamma) and fat-specific protein 27 (FSP27) expression level in epididymal adipose tissues (EAT) and subcutaneous adipose tissues (SAT) were detected along with other IR indicators. RESULTS: Calorie restriction (CR) significantly increased PPAR-gamma expression in EAT while decreased FSP27 expression. During re-feeding, both of the expression of PPAR gamma and FSP27 increased, even FSP27 returned to normal level when CUG for 4 weeks. Although PPAR-gamma expression declined slightly at 8 weeks, it was still much stronger than normal chow groups. However, no changes were seen in SAT. Relative insufficiency of FSP27 expression in EAT results in a decrease in lipid storage capacity, causing a series of path physiological changes that led to the formation of IR. Resveratrol inhibited the expression of PPAR-gamma and promoted FSP27 expression, thus fundamentally improving IR. CONCLUSIONS: The imbalance between adipose synthesis and storage mediated by PPAR-gamma / FSP27 in the EAT plays a pivotal role in the formation of IR during CUG. Resveratrol can correct fat formation and storage imbalance status by up-regulating FSP27 and down regulating PPAR-gamma expression level, ameliorating insulin sensitivity.

PMID- 27716233 TI - Age and HPV type as risk factors for HPV persistence after loop excision in patients with high grade cervical lesions: an observational study. AB - BACKGROUND: Persistent infections with high risk human papillomaviruses (HR-HPV) cause virtually all cervical cancers. METHODS: An observational study was conducted aiming to estimate the rate of HPV infection persistence after LEEP in patients with high grade squamous intraepithelial lesions (HSIL). Moreover, the study investigated if persistence is age related. For this reason a total of 110 patients were included between January 2010 and June 2015. RESULTS: At 6 months after LEEP the overall HPV infection persistence rate was 40.9 %, at 12 months 20 % and at 18 months 11.8 %. Type 16 showed the highest persistence rate: 27.3 % at 6 months, 12.7 % at 12 months and 10 % at 18 months after LEEP. The persistence for HPV type 16 at 6 months after LEEP was significantly higher in the group > =36.5 years old compared to the persistence rate in the group <36.5 years old (p = 0.0027, RR = 2.75, 95 %epsilon(1.34; 5.64)) (see Table 3). CONCLUSIONS: LEEP does not completely eradicate HPV infection. HPV persistence rate after LEEP is higher in infections with type 16 and in women older than 36.5 years. PMID- 27716236 TI - Biased image cropping and non-independent samples. AB - Any figure in a research article will typically represent only a small portion of the total data gained by a researcher for that experiment, and it is therefore key that the figure accurately reflects what was found overall. Furthermore, if individual observations form clusters with differing mean properties, those individual observations would not represent independent samples from the populations being compared. In this example, the question of how to fairly represent and treat image data is addressed. PMID- 27716235 TI - Access to primary health care services for Indigenous peoples: A framework synthesis. AB - BACKGROUND: Indigenous peoples often find it difficult to access appropriate mainstream primary health care services. Securing access to primary health care services requires more than just services that are situated within easy reach. Ensuring the accessibility of health care for Indigenous peoples who are often faced with a vast array of additional barriers including experiences of discrimination and racism, can be complex. This framework synthesis aimed to identify issues that hindered Indigenous peoples from accessing primary health care and then explore how, if at all, these were addressed by Indigenous health care services. METHODS: To be included in this framework synthesis papers must have presented findings focused on access to (factors relating to Indigenous peoples, their families and their communities) or accessibility of Indigenous primary health care services. Findings were imported into NVivo and a framework analysis undertaken whereby findings were coded to and then thematically analysed using Levesque and colleague's accessibility framework. RESULTS: Issues relating to the cultural and social determinants of health such as unemployment and low levels of education influenced whether Indigenous patients, their families and communities were able to access health care. Indigenous health care services addressed these issues in a number of ways including the provision of transport to and from appointments, a reduction in health care costs for people on low incomes and close consultation with, if not the direct involvement of, community members in identifying and then addressing health care needs. CONCLUSIONS: Indigenous health care services appear to be best placed to overcome both the social and cultural determinants of health which hamper Indigenous peoples from accessing health care. Findings of this synthesis also suggest that Levesque and colleague's accessibility framework should be broadened to include factors related to the health care system such as funding. PMID- 27716237 TI - Grayscale inversion radiographic view provided improved intra- and inter-observer reliabilities in measuring spinopelvic parameters in asymptomatic adult population. AB - BACKGROUND: Recently, a grayscale inversion view was reported to improve intra- and inter-observer reliabilities in measuring coronal curvature with Cobb and pedicle methods in scoliosis patients. However, the grayscale transformation has never been applied to the measurements of spinopelvic parameters. The purpose of this study was to compare the measurement reliabilities of the spinoplevic sagittal parameters between the 'Standard View' and the 'Grayscale Inversion View' in normal adult populations. METHODS: A total of 30 asymptomatic subjects aged between 30 and 40 years were included in this study. Whole-spine posteroanterior radiographs were used to measure the spinoplevic sagittal parameters including thoracic kyphosis (TK), lumbar lordosis (LL), sagittal vertical axis (SVA), pelvic incidence (PI), sacral slope (SS) and pelvic tilt (PT) in both standard view and grayscale inversion view. Two independent observers measured the parameters twice at a 2-week interval. Intra- and inter observer reliabilities were compared between the two radiographic views. The absolute differences between the two sets of measurements on each view were calculated and compared. RESULTS: The intra-class correlation coefficients (ICCs) of PI, PT and SVA were greater in the grayscale inversion view than in the standard view (0.972 vs 0.817, 0.937 vs 0.833 and 0.964 vs 0.901 for observer 1, respectively; 0.990 vs 0.826, 0.995 vs 0.842 and 0.969 vs 0.919 for observer 2, respectively). Overall, the improvement of ICC was greater in parameters of sagittal pelvic alignment than in those of sagittal spinal alignment. As for the mean absolute differences between two measurements, significant differences existed between the two views in terms of PI, PT and SVA (p = 0.014, 0.016 and 0.011 for observer 1, respectively; p = 0.014, 0.025 and 0.046 for observer 2, respectively). CONCLUSIONS: A grayscale inversion view provided improved intra- and inter-observer reliabilities in measuring spinoplevic alignment when compared with a standard view. This view was more useful in subjects whose pelvic anatomical structures can't be identified clearly on the standard X-ray view. PMID- 27716238 TI - International changes in end-of-life practices over time: a systematic review. AB - BACKGROUND: End-of-life policies are hotly debated in many countries, with international evidence frequently used to support or oppose legal reforms. Existing reviews are limited by their focus on specific practices or selected jurisdictions. The objective is to review international time trends in end-of life practices. METHODS: We conducted a systematic review of empirical studies on medical end-of-life practices, including treatment withdrawal, the use of drugs for symptom management, and the intentional use of lethal drugs. A search strategy was conducted in MEDLINE, EMBASE, Web of Science, Sociological Abstracts, PAIS International, Worldwide Political Science Abstracts, International Bibliography of the Social Sciences and CINAHL. We included studies that described physicians' actual practices and estimated annual frequency at the jurisdictional level. End-of-life practice frequencies were analyzed for variations over time, using logit regression. RESULTS: Among 8183 references, 39 jurisdiction-wide surveys conducted between 1990 and 2010 were identified. Of those, 22 surveys used sufficiently similar research methods to allow further statistical analysis. Significant differences were found across surveys in the frequency of treatment withdrawal, use of opiates or sedatives and the intentional use of lethal drugs (X 2 > 1000, p < 0.001 for all). Regression analyses showed increased use of opiates and sedatives over time (p < 0.001), which could reflect more intense symptom management at the end of life, or increase in these drugs to intentionally cause patients' death. CONCLUSION: The use of opiates and sedatives appears to have significantly increased over time between 1990 and 2010. Better distinction between practices with different legal status is required to properly interpret the policy significance of these changes. Research on the effects of public policies should take a comprehensive look at trends in end-of-life practice patterns and their associations with policy changes. PMID- 27716239 TI - Minimally important difference of the Child Oral Health Impact Profile for children with orofacial anomalies. AB - BACKGROUND: The Child Oral Health Impact Profile (COHIP) is an instrument designed to measure the self-reported oral health-related quality of life of children between the ages of 8 and 15, including domains for oral health, functional well-being, social-emotional well-being, school environment and self image. The purpose of this study was to estimate the minimally important difference (MID) of the COHIP for patients with cleft lip/palate. METHODS: Data from a 6-year, prospective, longitudinal cohort study of children with cleft lip/palate were analyzed to estimate the MID. Analysis was restricted to patients with data at baseline and first follow-up and not receiving a surgical intervention in the intervening years (N = 281). MIDs were estimated via the anchor-based method, using the Global Assessment of Change, and the effect size distribution method. RESULTS: Based on the distributional method, the minimally important differences were 0.16 (oral health), 0.12 (functional), 0.22 (social emotional), 0.21 (school environment) and 0.19 (self-image). MID anchor estimates for COHIP domains ranged from -0.32 to 0.84. The anchor-based and effect size MID estimates for the overall COHIP score were 2.95 and 0.25, respectively. CONCLUSION: The minimally important difference of the Child Oral Health Impact Profile is recommended for interpreting clinically meaningful change in patients with cleft lip/palate. PMID- 27716240 TI - Salvage surgery for local failures after stereotactic ablative radiotherapy for early stage non-small cell lung cancer. AB - INTRODUCTION: The literature on surgical salvage, i.e. lung resections in patients who develop a local recurrence following stereotactic ablative radiotherapy (SABR), is limited. We describe our experience with salvage surgery in nine patients who developed a local recurrence following SABR for early stage non-small cell lung cancer (NSCLC). METHODS: Patients who underwent surgical salvage for a local recurrence following SABR for NSCLC were identified from two Dutch institutional databases. Complications were scored using the Dindo-Clavien classification. RESULTS: Nine patients who underwent surgery for a local recurrence were identified. Median time to local recurrence was 22 months. Recurrences were diagnosed with CT- and/or 18FDG-PET-imaging, with four patients also having a pre-surgical pathological diagnosis. Extensive adhesions were observed during two resections, requiring conversion from a thoracoscopic procedure to thoracotomy during one of these procedures. Three patients experienced complications post-surgery; grade 2 (N = 2) and grade 3a (N = 1), respectively. All resection specimens showed viable tumor cells. Median length of hospital stay was 8 days (range 5-15 days) and 30-day mortality was 0 %. Lymph node dissection revealed mediastinal metastases in 3 patients, all of whom received adjuvant therapy. CONCLUSIONS: Our experience with nine surgical procedures for local recurrences post-SABR revealed two grade IIIa complications, and a 30-day mortality of 0 %, suggesting that salvage surgery can be safely performed after SABR. PMID- 27716241 TI - The relationship between depression and overactive bladder/urinary incontinence symptoms in the clinical OAB population. AB - BACKGROUND: To investigate the relationship between depression and overactive bladder (OAB)/urinary incontinence symptoms among the clinical OAB population. METHODS: Patients who were diagnosed with overactive bladder (OAB) and age matched control subjects without OAB were enrolled. Depression symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS-D). OAB/incontinence symptoms were assessed using the validated questionnaires: ICIQ UI, ICIQ-OAB, UDI-6, IIQ-7, and OAB-q. RESULTS: 27.5 % of OAB patients in our study had depression (HADS >=8), and 12 % of OAB patients had moderate to severe depression (HADS-D >=11). OAB patients reported significantly higher HADS-D depression scores compared to age-matched controls (5.3 +/- 3.9 versus 2.8 +/- 3.9, p = 0.004). OAB patients with depression reported more severe incontinence symptoms (ICIQ-UI), greater bother and more impact on quality of life (UDI-6, IIQ 7) compared to OAB patients without depression (p = 0.001, 0.01, <0.001, respectively). However there were no differences in ICIQ-OAB and OAB-q. Among OAB patients, there were positive correlations between the severity of depression symptoms and OAB/incontinence symptoms (p-values <0.001 to 0.035). CONCLUSIONS: 27.5 % of OAB patients have depression. OAB patients with depression reported more severe urinary incontinence symptoms, greater bother and more impact on quality of life compared to those without depression. Future studies are needed to further examine the mechanistic links between depression and OAB/urinary incontinence. PMID- 27716243 TI - Checklist for Early Recognition and Treatment of Acute Illness (CERTAIN): evolution of a content management system for point-of-care clinical decision support. AB - BACKGROUND: The Checklist for Early Recognition and Treatment of Acute Illness (CERTAIN) is an international collaborative project with the overall objective of standardizing the approach to the evaluation and treatment of critically ill patients world-wide, in accordance with best-practice principles. One of CERTAIN's key features is clinical decision support providing point-of-care information about common acute illness syndromes, procedures, and medications in an index card format. METHODS: This paper describes 1) the process of developing and validating the content for point-of-care decision support, and 2) the content management system that facilitates frequent peer-review and allows rapid updates of content across different platforms (CERTAIN software, mobile apps, pdf booklet) and different languages. RESULTS: Content was created based on survey results of acute care providers and validated using an open peer-review process. Over a 3 year period, CERTAIN content expanded to include 67 syndrome cards, 30 procedure cards, and 117 medication cards. 127 (59 %) cards have been peer reviewed so far. Initially MS Word(r) and Dropbox(r) were used to create, store, and share content for peer-review. Recently Google Docs(r) was used to make the peer-review process more efficient. However, neither of these approaches met our security requirements nor has the capacity to instantly update the different CERTAIN platforms. CONCLUSION: Although we were able to successfully develop and validate a large inventory of clinical decision support cards in a short period of time, commercially available software solutions for content management are suboptimal. Novel custom solutions are necessary for efficient global point of care content system management. PMID- 27716242 TI - Zika Virus on a Spreading Spree: what we now know that was unknown in the 1950's. AB - Zika virus (ZIKV) is a mosquito-borne flavivirus that is transmitted through the bite of Aedes spp mosquitoes and less predominantly, through sexual intercourse. Prior to 2007, ZIKV was associated with only sporadic human infections with minimal or no clinical manifestations. Recently the virus has caused disease outbreaks from the Pacific Islands, the Americas, and off the coast of West Africa with approximately 1.62 million people suspected to be infected in more than 60 countries around the globe. The recent ZIKV outbreaks have been associated with guillain-barre syndrome, congenital syndrome (microcephaly, congenital central nervous system anomalies), miscarriages, and even death. This review summarizes the path of ZIKV outbreak within the last decade, highlights three novel modes of ZIKV transmission associated with recent outbreaks, and points to the hallmarks of congenital syndrome. The review concludes with a summary of challenges facing ZIKV research especially the control of ZIKV infection in the wake of most recent data showing that anti-dengue virus antibodies enhance ZIKV infection. PMID- 27716244 TI - Performance and time to become negative after treatment of three malaria rapid diagnostic tests in low and high malaria transmission settings. AB - BACKGROUND: The performance of different malaria rapid diagnostic tests (RDT) may be influenced by transmission intensity and by the length of time each test requires to become negative after treatment and patient's recovery. METHODS: Results of three RDTs (two HRP2 and one pLDH antigen-based tests) were compared to blood smear microscopy (the gold standard method) in children under 5 years of age living in a high versus low malaria intensity setting in southwestern Uganda. In each setting, 212 children, who tested positive by at least one RDT and by microscopy, were treated with artemether-lumefantrine. RDTs and microscopy were then repeated at fixed intervals to estimate each test's time to negativity after treatment and patient recovery. RESULTS: In the two settings, sensitivities ranged from 98.4 to 99.2 % for the HRP2 tests and 94.7 to 96.1 % for the pLDH test. Specificities were 98.9 and 98.8 % for the HRP2 tests and 99.7 % for the pLDH test in the low-transmission setting and 79.7, 80.7 and 93.9 %, respectively, in the high-transmission setting. Median time to become negative was 35-42 or more days for the HRP2 tests and 2 days for the pLDH test. CONCLUSIONS: High transmission contexts and a long time to become negative resulted in considerably reduced specificities for the HRP2 tests. Choice of RDT for low- versus high-transmission settings should balance risks and benefits of over-treatment versus missing malaria cases. TRIAL REGISTRATION: Registry number at ClinicalTrial.gov: NCT01325974. PMID- 27716245 TI - Research for Policy (R4P): development of a reflection tool for researchers to improve knowledge utilization. AB - BACKGROUND: To improve knowledge utilization in policymaking, alignment between researchers and policymakers during knowledge production is essential, but difficult to maintain. In three previously reported case studies, we extensively evaluated complex research projects commissioned by policymakers to investigate how alignment is achieved in a research process and to discover ways to enhance knowledge contributions to health policy. In the present study, we investigated how the findings of these three research projects could be integrated into a practical tool for researchers to enhance their contribution to evidence-based policy. METHODS: A cross-case analysis was conducted to integrate the findings of the evaluation of the three research projects and to identify important alignment areas in these projects. By means of an iterative process, we prepared a tool that includes reflection questions for researchers. The "Research for Policy" tool was tested with input from the project managers of three new research projects. Based on the findings, the final version of the Research for Policy tool was prepared. RESULTS: By cross-case analysis of the three case studies, the following important alignment areas were identified: the goal, quality, relevance, timing, and presentation of research, the tasks and authorities of actors, the consultative structure and vertical alignment within organizations, and the organizational environment. The project managers regarded the Research for Policy tool as a useful checklist for addressing the important alignment areas in a research project. Based on their feedback, the illustrative examples from the case studies were added to the reflection questions. The project managers suggested making the tool accessible not only to researchers but also to policymakers. The format of the Research for Policy tool was further adjusted to users' needs by adding clickable links. CONCLUSIONS: Alignment between research and policymaking requires continuous efforts and a clear understanding of process issues in the research project. The Research for Policy tool offers practical alignment guidance and facilitates reflection on process issues, which supports researchers in aligning with policymakers and in acting in a context-sensitive way. PMID- 27716246 TI - Effects of coenzyme Q10 supplementation on antioxidant capacity and inflammation in hepatocellular carcinoma patients after surgery: a randomized, placebo controlled trial. AB - BACKGROUND: It has been reported that higher levels of oxidative stress and inflammation play a key role in the progression of hepatocellular carcinoma (HCC) after surgery. Coenzyme Q10 is an endogenous lipid-soluble antioxidant. To date, no intervention study has investigated coenzyme Q10 supplementation in HCC patients after surgery. The purpose of this study was to investigate oxidative stress, antioxidant enzymes activity, and inflammation levels in HCC patients after surgery following administration of coenzyme Q10 (300 mg/day). METHODS: This study was designed as a single-blinded, randomized, parallel, placebo controlled study. Patients who were diagnosed with primary HCC (n = 41) and were randomly assign to a placebo (n = 20) or coenzyme Q10 (300 mg/day, n = 21) group after surgery. The intervention lasted for 12 weeks. Plasma coenzyme Q10, vitamin E, oxidative stress antioxidant enzymes activity and inflammatory markers levels were measured. RESULTS: The oxidative stress (p = 0.04) and inflammatory markers (hs-CRP and IL-6, p < 0.01) levels were significantly decreased, and the antioxidant enzymes activity was significantly increased (p < 0.01) after 12 weeks of coenzyme Q10 supplementation. In addition, the coenzyme Q10 level was significantly negatively correlated with the oxidative stress (p = 0.01), and positively correlated with antioxidant enzymes activity (SOD, p = 0.01; CAT, p < 0.05; GPx, p = 0.04) and vitamin E level (p = 0.01) after supplementation. CONCLUSION: In conclusion, we demonstrated that a dose of 300 mg/d of coenzyme Q10 supplementation significantly increased the antioxidant capacity and reduced the oxidative stress and inflammation levels in HCC patients after surgery.

AB - BACKGROUND: Despite best evidence demonstrating the effectiveness of increased intensity of exercise after stroke, current levels of therapy continue to be below those required to optimise motor recovery. We developed and tested an implementation intervention that aims to increase arm exercise in stroke rehabilitation. The aim of this study was to illustrate the use of a behaviour change framework, the Behaviour Change Wheel, to identify the mechanisms of action that explain how the intervention produced change. METHODS: We implemented the intervention at three stroke rehabilitation units in the United Kingdom. A purposive sample of therapy team members were recruited to participate in semi structured interviews to explore their perceptions of how the intervention produced change at their work place. Audio recordings were transcribed and imported into NVivo 10 for content analysis. Two coders separately analysed the transcripts and coded emergent mechanisms. Mechanisms were categorised using the Theoretical Domains Framework (TDF) (an extension of the Capability, Opportunity, Motivation and Behaviour model (COM-B) at the hub of the Behaviour Change Wheel). RESULTS: We identified five main mechanisms of action: 'social/professional role and identity', 'intentions', 'reinforcement', 'behavioural regulation' and 'beliefs about consequences'. At the outset, participants viewed the research team as an external influence for whom they endeavoured to complete the study activities. The study design, with a focus on implementation in real world settings, influenced participants' intentions to implement the intervention components. Monthly meetings between the research and therapy teams were central to the intervention and acted as prompt or reminder to sustain implementation. The phased approach to introducing and implementing intervention components influenced participants' beliefs about the feasibility of implementation. CONCLUSIONS: The Behaviour Change Wheel, and in particular the Theoretical Domains Framework, were used to investigate mechanisms of action of an implementation intervention. This approach allowed for consideration of a range of possible mechanisms, and allowed us to categorise these mechanisms using an established behaviour change framework. Identification of the mechanisms of action, following testing of the intervention in a number of settings, has resulted in a refined and more robust intervention programme theory for future testing. PMID- 27716248 TI - Instantaneous phase difference analysis between thoracic and abdominal movement signals based on complementary ensemble empirical mode decomposition. AB - BACKGROUND: Thoracoabdominal asynchrony is often adopted to discriminate respiratory diseases in clinics. Conventionally, Lissajous figure analysis is the most frequently used estimation of the phase difference in thoracoabdominal asynchrony. However, the temporal resolution of the produced results is low and the estimation error increases when the signals are not sinusoidal. Other previous studies have reported time-domain procedures with the use of band-pass filters for phase-angle estimation. Nevertheless, the band-pass filters need calibration for phase delay elimination. METHODS: To improve the estimation, we propose a novel method (named as instantaneous phase difference) that is based on complementary ensemble empirical mode decomposition for estimating the instantaneous phase relation between measured thoracic wall movement and abdominal wall movement. To validate the proposed method, experiments on simulated time series and human-subject respiratory data with two breathing types (i.e., thoracic breathing and abdominal breathing) were conducted. Latest version of Lissajous figure analysis and automatic phase estimation procedure were compared. RESULTS: The simulation results show that the standard deviations of the proposed method were lower than those of two other conventional methods. The proposed method performed more accurately than the two conventional methods. For the human-subject respiratory data, the results of the proposed method are in line with those in the literature, and the correlation analysis result reveals that they were positively correlated with the results generated by the two conventional methods. Furthermore, the standard deviation of the proposed method was also the smallest. CONCLUSIONS: To summarize, this study proposes a novel method for estimating instantaneous phase differences. According to the findings from both the simulation and human-subject data, our approach was demonstrated to be effective. The method offers the following advantages: (1) improves the temporal resolution, (2) does not introduce a phase delay, (3) works with non sinusoidal signals, (4) provides quantitative phase estimation without estimating the embedded frequency of breathing signals, and (5) works without calibrated measurements. The results demonstrate a higher temporal resolution of the phase difference estimation for the evaluation of thoracoabdominal asynchrony.

PMID- 27716250 TI - The impact of reimbursement systems on equity in access and quality of primary care: A systematic literature review. AB - BACKGROUND: Reimbursement systems provide incentives to health care providers and may drive physician behaviour. This review assesses the impact of reimbursement system on socioeconomic and racial inequalities in access, utilization and quality of primary care. METHODS: A systematic search was performed in Web of Science and PubMed for English language studies published between 1980 and 2013, supplemented by reference tracking. Articles were selected based on inclusion criteria, and data extraction and critical appraisal were performed by two authors independently. Data were synthesized in a narrative manner and categorized according to study outcome and reimbursement system. RESULTS: Twenty seven articles, mostly from the United States and United Kingdom, were included in the data synthesis. Reimbursement systems seem to have limited effect on socioeconomic and racial inequity in access, utilization and quality of primary care. Capitation might have a more beneficial impact on inequity in access to primary care and number of ambulatory care sensitive admissions than fee-for service, but did worse in patient satisfaction. Pay-for-performance had little or no impact on socioeconomic and racial inequity in the management of diabetes, cardiovascular diseases, chronic obstructive pulmonary disease, and preventive services. CONCLUSION: We found little scientific evidence supporting an association between reimbursement system and socioeconomic or racial inequity in access, utilization and quality of primary care. Overall, few studies addressed this research question, and heterogeneity in context and outcomes complicates comparisons across studies. Further empirical studies are warranted. PMID- 27716251 TI - Seroprevalence of human immunodeficiency virus, hepatitis B and C viruses, and Treponema pallidum infections among blood donors at Shiyan, Central China. AB - BACKGROUND: Ordinary screening of transfusion-transmissible infections (TTIs) among blood donors is essential for blood transfusion. Although there is several TTIs studies focus on human immunodeficiency virus, hepatitis B and C viruses, and Treponema pallidum infections in China, it is no data to illustrate any firm conclusion from Shiyan City, Central China. It aims to verify the seroprevalence of TTIs among blood donors at Shiyan. METHODS: A retrospective analysis of blood donors' information was conducted for the presence of HIV, HBV, HCV and T. pallidum. Logistic regression analysis was used to demonstrate risk factors including age, gender and occupation associated with them. The variation tendency in seroprevalence of these TTIs over the study period was evaluated by Cochran Armitage trend test. RESULTS: Of 211 639 blood donors, 2 858 (1.35 %) had serological evidence of TTIs. The seroprevalence of HIV, HBV, HCV and T. pallidum were 0.08 %, 0.51 %, 0.20 % and 0.57 %, respectively. However, the co-infection prevalence of TTIs has not been detected. The HIV seropositivity significantly increased among female donors (OR = 1.63, P < 0.001) and farmers (OR = 2.02, P = 0.020). Significantly increased HBV seropositivity was only observed framers (OR = 1.87, P <0.001) compared to workers. Analogously, significantly increased HCV seropositivity was observed among farmers (OR = 2.59, P < 0.001), students (OR = 2.43, P < 0.001), merchants (OR = 1.70, P = 0.014) and others (OR = 1.78, P =0.001). The T. pallidum seroprevalence was notably increased among female (OR = 1.54, P < 0.001), and farmers (OR = 1.70, P <0.001). Moreover, significantly increasing trends of HIV (Z = -6.88, P < 0.01), HBV (Z = -4.52, P < 0.01), HCV (Z = -4.16, P < 0.01) and T. pallidum (Z = -1.36, P < 0.01) seropositivity were observed over the study period. CONCLUSIONS: It originally offers a substantial prevalence of TTIs among blood donors at Shiyan, Central China. Severe blood donor selection and all-inclusive screening of blood are highly recommended. It might be helpful for developing and updating guidance for blood safety. TRIAL REGISTRATION: Retrospectively registered. PMID- 27716252 TI - Do countries rely on the World Health Organization for translating research findings into clinical guidelines? A case study. AB - BACKGROUND: The World Health Organization's (WHO) antiretroviral therapy (ART) guidelines have generally been adopted rapidly and with high fidelity by countries in sub-Saharan Africa. Thus far, however, WHO has not published specific guidance on nutritional care and support for (non-pregnant) adults living with HIV despite a solid evidence base for some interventions. This offers an opportunity for a case study on whether national clinical guidelines in sub Saharan Africa provide concrete recommendations in the face of limited guidance by WHO. This study, therefore, aims to determine if national HIV treatment guidelines in sub-Saharan Africa contain specific guidance on nutritional care and support for non-pregnant adults living with HIV. METHODS: We identified the most recent national HIV treatment guidelines in sub-Saharan African countries with English as an official language. Using pre-specified criteria, we determined for each guideline whether it provides guidance to clinicians on each of five components of nutritional care and support for adults living with HIV: assessment of nutritional status, dietary counseling, micronutrient supplementation, ready to-use therapeutic or supplementary foods, and food subsidies. RESULTS: We found that national HIV treatment guidelines in sub-Saharan Africa generally do not contain concrete recommendations on nutritional care and support for non-pregnant adults living with HIV. CONCLUSIONS: Given that decisions on nutritional care and support are inevitably being made at the clinician-patient level, and that clinicians have a relative disadvantage in systematically identifying, summarizing, and weighing up research evidence compared to WHO and national governments, there is a need for more specific clinical guidance. In our view, such guidance should at a minimum recommend daily micronutrient supplements for adults living with HIV who are in pre-ART stages, regular dietary counseling, periodic assessment of anthropometric status, and additional nutritional management of undernourished patients. More broadly, our findings suggest that countries in sub-Saharan Africa look to WHO for guidance in translating evidence into clinical guidelines. It is, thus, likely that the development of concrete recommendations by WHO on nutritional interventions for people living with HIV would lead to more specific guidelines at the country-level and, ultimately, better clinical decisions and treatment outcomes. PMID- 27716253 TI - Nurse-administered intravitreal injections of anti-VEGF: study protocol for noninferiority randomized controlled trial of safety, cost and patient satisfaction. AB - BACKGROUND: Intravitreal injections (IVI) of anti-vascular endothelial growth factor (anti-VEGF) now improve or stabilize visual acuity in a number of previously untreatable eye diseases, of which the main are age-related macular degeneration, retinal vein occlusion and diabetic macular edema. Most patients require multiple injections over lengthy periods of time and the prevalence of treatable conditions is increasing. Anti-VEGF IVI normally administered by physicians, therefore represent a considerable workload on ophthalmologic clinics and will continue to do so in the near future. Nurse-administered IVI may relieve this workload, but the safety, cost and patient satisfaction of such an extended role for nurses in ophthalmologic clinics has not earlier been investigated. To investigate these outcomes following independent anti-VEGF IVI by trained nurses, a noninferiority randomized controlled trial is being conducted. METHODS/DESIGN: Patients eligible for anti-VEGF treatment, minimum 304, are recruited and randomized to IVI administration by either trained nurses or physicians. The primary outcome is safety, measured by difference in mean change in visual acuity between the two groups during an observation period of 12 months. Secondary outcomes are incidence of ocular adverse events, cost per patient and patient satisfaction. DISCUSSION: This study protocol describes the design of the first randomized controlled trial of nurse-administered IVI of anti-VEGF. The study is designed to examine safety, cost and patient satisfaction during 12 months follow up. TRIAL REGISTRATION: ClinicalTrials.gov NCT02359149 . Registered February 4, 2015.

AB - BACKGROUND: Little is known about action-perception learning processes underlying prosthetic skills in body-powered prosthesis users. Body-powered prostheses are controlled through a harness connected by a cable that might provide for limited proprioceptive feedback. This study aims to test transfer of training basic tasks to functional tasks and to describe the changes over time in kinematics of basic tasks of novice body-powered prosthesis users. METHODS: Thirty able-bodied participants and 17 controls participated in the study, using a body-powered prosthetic simulator. Participants in the training group were divided over four groups and practiced during a 2-week-period either direct grasping, indirect grasping, fixation, or a combination of these tasks. Deformable objects with different compliances had to be manipulated while kinematic variables and grip force control were assessed. Functional performance was measured with the Southampton Hand Assessment Procedure (SHAP) prior to and after the training sessions, and after 2 weeks and 3 months retention. The control group only performed the SHAP tests. RESULTS: All four training groups and the control group improved on the SHAP, also after a period of non-use. Type of training had a small but significant influence on the improvements of the SHAP score. On a kinematic level movement times decreased and hook closing velocities increased over time. The indirect grasping group showed significantly shorter plateau times than the other training groups. Grip force control only improved a little over training. CONCLUSIONS: Training action-perception couplings of body-powered prosthesis in basic tasks transferred to functional tasks and this lasted after a period of non-use. During training movement times decreased and the indirect grasping group showed advantages. It is advisable to start body-powered training with indirect grasping tasks but also to practice hook-object orientations.

AB - BACKGROUND: Generalized Joint Hypermobility (GJH) is associated with increased risk of musculoskeletal joint pain. We investigated neuromuscular performance and muscle activation strategy. METHODS: Girls with GJH and non-GJH (NGJH) performed isometric knee flexions (90 degrees ,110 degrees ,130 degrees ), and extensions (90 degrees ) at 20 % Maximum Voluntary Contraction, and explosive isometric knee flexions while sitting. EMG was recorded from knee flexor and extensor muscles. RESULTS: Early rate of torque development was 53 % faster for GJH. Reduced hamstring muscle activation in girls with GJH was found while knee extensor and calf muscle activation did not differ between groups. Flexion-extension and medial-lateral co-activation ratio during flexions were higher for girls with GJH than NGJH girls. CONCLUSIONS: Girls with GJH had higher capacity to rapidly generate force than NGJH girls which may reflect motor adaptation to compensate for hypermobility. Higher medial muscle activation indicated higher levels of medial knee joint compression in girls with GJH. Increased flexion-extension co activation ratios in GJH were explained by decreased agonist drive to the hamstrings.

AB - BACKGROUND: Physicians' daily work is increasingly affected by the use of emails, text messages and cell phone calls with their patients. The aim of this study was to describe their use between primary-care physicians and patients in a French speaking part of Switzerland. METHODS: A cross-sectional mail survey was conducted among all primary-care physicians of Geneva canton (n = 636). The questionnaire focused on the frequency of giving access to, type of use, advantages and disadvantages of email, cell phone calls and text messages communication between physicians and patients. RESULTS: Six hundred thirty-six questionnaires were mailed, 412 (65 %) were returned and 372 (58 %) could be analysed (37 refusals and three blanks). Seventy-two percent physicians gave their email-address and 74 % their cell phone number to their patients. Emails were used to respond to patients' questions (82 %) and change appointments (72 %) while cell phone calls and text messages were used to follow patients' health conditions. Sixty-four percent of those who used email communication never discussed the rules for email exchanges, and 54 % did not address confidentiality issues with their patients. Most commonly identified advantages of emails, cell phone calls and text messages were improved relationship with the patient, saving time (for emails) and improving the follow-up (for cell phone and text messages). The main disadvantages included misuse by the patient, interference with private life and lack of reimbursement. CONCLUSIONS: These tools are widely used by primary-care physicians with their patients. More attention should be paid to confidentiality, documentation and reimbursement when using email communication in order to optimize its use. PMID- 27716257 TI - Characterization of virus-derived small interfering RNAs in Apple stem grooving virus-infected in vitro-cultured Pyrus pyrifolia shoot tips in response to high temperature treatment. AB - BACKGROUND: Heat treatment (known as thermotherapy) together with in vitro culture of shoot meristem tips is a commonly used technology to obtain virus-free germplasm for the effective control of virus diseases in fruit trees. RNA silencing as an antiviral defense mechanism has been implicated in this process. To understand if high temperature-mediated acceleration of the host antiviral gene silencing system in the meristem tip facilitates virus-derived small interfering RNAs (vsiRNA) accumulation to reduce the viral RNA titer in the fruit tree meristem tip cells, we used the Apple stem grooving virus (ASGV)-Pyrus pyrifolia pathosystem to explore the possible roles of vsiRNA in thermotherapy. RESULTS: At first we determined the full-length genome sequence of the ASGV-Js2 isolate and then profiled vsiRNAs in the meristem tip of in vitro-grown pear (cv. 'Jinshui no. 2') shoots infected by ASGV-Js2 and cultured at 24 and 37 degrees C. A total of 7,495 and 7,949 small RNA reads were obtained from the tips of pear shoots cultured at 24 and 37 degrees C, respectively. Mapping of the vsiRNAs to the ASGV-Js2 genome revealed that they were unevenly distributed along the ASGV Js2 genome, and that 21- and 22-nt vsiRNAs preferentially accumulated at both temperatures. The 5'-terminal nucleotides of ASGV-specific siRNAs in the tips cultured under different temperatures had a similar distribution pattern, and the nucleotide U was the most frequent. RT-qPCR analyses suggested that viral genome accumulation was drastically compromised at 37 degrees C compared to 24 degrees C, which was accompanied with the elevated levels of vsiRNAs at 37 degrees C. As plant Dicer-like proteins (DCLs), Argonaute proteins (AGOs), and RNA-dependent RNA polymerases (RDRs) are implicated in vsiRNA biogenesis, we also cloned the partial sequences of PpDCL2,4, PpAGO1,2,4 and PpRDR1 genes, and found their expression levels were up-regulated in the ASGV-infected pear shoots at 37 degrees C. CONCLUSIONS: Collectively, these results showed that upon high temperature treatment, the ASGV-infected meristem shoot tips up-regulated the expression of key genes in the RNA silencing pathway, induced the biogenesis of vsiRNAs and inhibited viral RNA accumulation. This study represents the first report on the characterization of the vsiRNA population in pear plants infected by ASGV-Js2, in response to high temperature treatment. PMID- 27716258 TI - Rifaximin is an effective alternative to metronidazole for the treatment of chronic enteropathy in dogs: a randomised trial. AB - BACKGROUND: A clinical trial was conducted in order to assess the efficacy of rifaximin, a broad-spectrum antibiotic with negligible gastrointestinal absorption, in comparison with metronidazole, a commonly employed antimicrobial drug, in dogs with chronic enteropathy. Twenty-four pet dogs were randomly enrolled into two different groups: MET group (10 dogs) and RIF group (14 dogs). Dogs of MET group received metronidazole 15 mg/kg q12h for 21 days by oral route, whereas dogs of RIF group, were given rifaximin 25 mg/kg q12h for 21 days by oral route. Clinical signs of disease were evaluated the day before the beginning of drug administration (D0), and at the end of treatment (D21), by means of Canine IBD Activity Index (CIBDAI). Blood levels of C-reactive protein (CRP) at D0 and D21 were also measured, as another parameter of treatment efficacy. The primary outcome measure of efficacy was the complete remission at D21, defined as a 75 % or greater decrease of CIBDAI; secondary outcome measures were the variation of mean CIBDAI scores, of mean CRP serum levels, and any observed adverse effect from D0 to D21. RESULTS: Treatment with metronidazole or rifaximin greatly improved the clinical signs of disease in each group: in MET group the complete remission was achieved in 8 of 10 dogs (80.0 %), and partial remission in 2 subjects (20.0 %). In RIF group, 12 of 14 dogs showed complete remission (85.7 %), and the remaining 2 dogs were in partial remission (14.3 %). There were also significant decreases of CIBDAI scores (P = 0.002 and P = 0.0002 for MET and RIF, respectively), and CRP levels (P = 0.002 and P = 0.0001 for MET and RIF, respectively) compared to pre-treatment values in both groups. No significant difference, however, was found when comparing MET and RIF groups. No relevant side-effect was reported during the trial with either drugs. CONCLUSIONS: The present study showed, for the first time, that oral rifaximin could represent an effective alternative to metronidazole for the induction of clinical remission in dogs with chronic enteropathy. PMID- 27716259 TI - Microarray data analysis to identify crucial genes regulated by CEBPB in human SNB19 glioma cells. AB - BACKGROUND: Glioma is one of the most common primary malignancies in the brain or spine. The transcription factor (TF) CCAAT/enhancer binding protein beta (CEBPB) is important for maintaining the tumor initiating capacity and invasion ability. To investigate the regulation mechanism of CEBPB in glioma, microarray data GSE47352 was analyzed. METHODS: GSE47352 was downloaded from Gene Expression Omnibus, including three samples of SNB19 human glioma cells transduced with non target control small hairpin RNA (shRNA) lentiviral vectors for 72 h (normal glioma cells) and three samples of SNB19 human glioma cells transduced with CEBPB shRNA lentiviral vectors for 72 h (CEBPB-silenced glioma cells). The differentially expressed genes (DEGs) were screened using limma package and then annotated. Afterwards, the Database for Annotation, Visualization, and Integrated Discovery (DAVID) software was applied to perform enrichment analysis for the DEGs. Furthermore, the protein-protein interaction (PPI) network and transcriptional regulatory network were constructed using Cytoscape software. RESULTS: Total 529 DEGs were identified in the normal glioma cells compared with the CEBPB-silenced glioma cells, including 336 up-regulated and 193 down regulated genes. The significantly enriched pathways included chemokine signaling pathway (which involved CCL2), focal adhesion (which involved THBS1 and THBS2), TGF-beta signaling pathway (which involved THBS1, THBS2, SMAD5, and SMAD6) and chronic myeloid leukemia (which involved TGFBR2 and CCND1). In the PPI network, CCND1 (degree = 29) and CCL2 (degree = 12) were hub nodes. Additionally, CEBPB and TCF12 might function in glioma through targeting others (CEBPB -> TCF12, CEBPB -> TGFBR2, and TCF12 -> TGFBR2). CONCLUSIONS: CEBPB might act in glioma by regulating CCL2, CCND1, THBS1, THBS2, SMAD5, SMAD6, TGFBR2, and TCF12. PMID- 27716260 TI - Perinatal mortality associated with use of uterotonics outside of Comprehensive Emergency Obstetric and Neonatal Care: a cross-sectional study. AB - BACKGROUND: Prior studies have shown that using uterotonics to augment or induce labor before arrival at comprehensive Emergency Obstetric and Neonatal Care (CEmONC) settings (henceforth, "outside uterotonics") may contribute to perinatal mortality in low- and middle-income countries. We estimate its effect on perinatal mortality in rural Bangladesh. METHODS: Using hospital records (23986 singleton term births, Jan 1, 2009-Dec 31, 2015) from rural Bangladesh, we use a logistic regression model to estimate the increased risk of perinatal death from uterotonics administered outside a CEmONC facility. RESULTS: Among term births (>=37 weeks gestation), the risk of perinatal death adjusted for key confounders is significantly increased among women reporting uterotonic use outside of CEmONC (OR = 3 . 0, 95 % CI = 2 . 4,3 . 7). This increased risk is particularly high for fresh stillbirths (OR = 4 . 0, 95 % CI = 3 . 0,5 . 3) and intrapartum-related causes of early neonatal deaths (birth asphyxia) (OR = 3 . 1, 95 % CI = 2 . 2,4 . 5). CONCLUSIONS: In this sample, outside uterotonic use was associated with substantially increased risk of fresh stillbirths, deaths due to birth asphyxia, and all perinatal deaths. In settings of high uterotonic use outside of controlled settings, substantial improvement in both stillbirth and early neonatal mortality may be made by reducing such use. PMID- 27716261 TI - Enhancing health care equity with Indigenous populations: evidence-based strategies from an ethnographic study. AB - BACKGROUND: Structural violence shapes the health of Indigenous peoples globally, and is deeply embedded in history, individual and institutional racism, and inequitable social policies and practices. Many Indigenous communities have flourished, however, the impact of colonialism continues to have profound health effects for Indigenous peoples in Canada and internationally. Despite increasing evidence of health status inequities affecting Indigenous populations, health services often fail to address health and social inequities as routine aspects of health care delivery. In this paper, we discuss an evidence-based framework and specific strategies for promoting health care equity for Indigenous populations. METHODS: Using an ethnographic design and mixed methods, this study was conducted at two Urban Aboriginal Health Centres located in two inner cities in Canada, which serve a combined patient population of 5,500. Data collection included in depth interviews with a total of 114 patients and staff (n = 73 patients; n = 41 staff), and over 900 h of participant observation focused on staff members' interactions and patterns of relating with patients. RESULTS: Four key dimensions of equity-oriented health services are foundational to supporting the health and well-being of Indigenous peoples: inequity-responsive care, culturally safe care, trauma- and violence-informed care, and contextually tailored care. Partnerships with Indigenous leaders, agencies, and communities are required to operationalize and tailor these key dimensions to local contexts. We discuss 10 strategies that intersect to optimize effectiveness of health care services for Indigenous peoples, and provide examples of how they can be implemented in a variety of health care settings. CONCLUSIONS: While the key dimensions of equity-oriented care and 10 strategies may be most optimally operationalized in the context of interdisciplinary teamwork, they also serve as health equity guidelines for organizations and providers working in various settings, including individual primary care practices. These strategies provide a basis for organizational-level interventions to promote the provision of more equitable, responsive, and respectful PHC services for Indigenous populations. Given the similarities in colonizing processes and Indigenous peoples' experiences of such processes in many countries, these strategies have international applicability. PMID- 27716263 TI - Serum bicarbonate concentration and the risk of cardiovascular disease and death in type 2 diabetes: the Fremantle Diabetes Study. AB - BACKGROUND: Serum bicarbonate is associated with mortality, heart failure (HF) and progression of renal failure in studies of healthy people and patients with chronic kidney disease, but the significance of these observations in unselected patients with diabetes in the general population is unknown. The aim of this study was to determine whether serum bicarbonate was associated with mortality and cardiovascular disease risk in type 2 diabetes. METHODS: Baseline serum bicarbonate was available for 1283 well-characterized community-based patients (mean +/- SD age 64.1 +/- 11.3 years, 48.7 % males) from the longitudinal observational Fremantle Diabetes Study followed for a mean of 12 years. Associations between serum bicarbonate and mortality, coronary heart disease (CHD) and incident HF were analysed using Cox proportional hazards regression. RESULTS: Serum bicarbonate was independently and negatively associated with incident CHD. For each 1 mmol/L increase in bicarbonate, the hazard ratio for CHD was 0.95 (95 % confidence interval 0.92-0.99) after adjustment for age as time scale, age at baseline, sex, English fluency, diabetes duration, loge(serum triglycerides), loge(urinary albumin: creatinine ratio), peripheral sensory neuropathy and peripheral arterial disease. There were no independent associations between serum bicarbonate and all-cause mortality [0.98 (0.95 1.004)] or incident HF [0.99 (0.95-1.03)]. CONCLUSIONS: Serum bicarbonate was a significant independent predictor of incident CHD but not death or HF in community-based patients with type 2 diabetes. This supports intervention trials of bicarbonate replacement in type 2 patients at risk of CHD and who have a low serum bicarbonate concentration. PMID- 27716264 TI - Current state of ethics literature synthesis: a systematic review of reviews. AB - BACKGROUND: Modern standards for evidence-based decision making in clinical care and public health still rely solely on eminence-based input when it comes to normative ethical considerations. Manuals for clinical guideline development or health technology assessment (HTA) do not explain how to search, analyze, and synthesize relevant normative information in a systematic and transparent manner. In the scientific literature, however, systematic or semi-systematic reviews of ethics literature already exist, and scholarly debate on their opportunities and limitations has recently bloomed. METHODS: A systematic review was performed of all existing systematic or semi-systematic reviews for normative ethics literature on medical topics. The study further assessed how these reviews report on their methods for search, selection, analysis, and synthesis of ethics literature. RESULTS: We identified 84 reviews published between 1997 and 2015 in 65 different journals and demonstrated an increasing publication rate for this type of review. While most reviews reported on different aspects of search and selection methods, reporting was much less explicit for aspects of analysis and synthesis methods: 31 % did not fulfill any criteria related to the reporting of analysis methods; for example, only 25 % of the reviews reported the ethical approach needed to analyze and synthesize normative information. CONCLUSIONS: While reviews of ethics literature are increasingly published, their reporting quality for analysis and synthesis of normative information should be improved. Guiding questions are: What was the applied ethical approach and technical procedure for identifying and extracting the relevant normative information units? What method and procedure was employed for synthesizing normative information? Experts and stakeholders from bioethics, HTA, guideline development, health care professionals, and patient organizations should work together to further develop this area of evidence-based health care. PMID- 27716262 TI - New aspects in the management of pneumonia. AB - Despite improvements in the management of community-acquired pneumonia (CAP), morbidity and mortality are still high, especially in patients with more severe disease. Early and appropriate antibiotics remain the cornerstone in the treatment of CAP. However, two aspects seem to contribute to a worse outcome: an uncontrolled inflammatory reaction and an inadequate immune response. Adjuvant treatments, such as corticosteroids and intravenous immunoglobulins, have been proposed to counterbalance these effects. The use of corticosteroids in patients with severe CAP and a strong inflammatory reaction can reduce the time to clinical stability, the risk of treatment failure, and the risk of progression to acute respiratory distress syndrome. The administration of intravenous immunoglobulins seems to reinforce the immune response to the infection in particular in patients with inadequate levels of antibodies and when an enriched IgM preparation has been used; however, more studies are needed to determinate their impact on outcome and to define the population that will receive more benefit.

PMID- 27716266 TI - Drug prescribing patterns at primary health care level and related out-of-pocket expenditures in Tajikistan. AB - BACKGROUND: The Government of Tajikistan is reforming its health system to make access more equitable. Nonetheless, out-of-pocket expenditures (OPE) remain a key modality for purchasing health care. Drugs remain a major driver of household expenditures for health. We conducted a household survey to investigate drug prescribing patterns at primary health care (PHC) level as well as the related OPE. METHODS: Adult patients in eight districts who had visited a PHC facility in the period March to May 2014 were interviewed at home, using a structured questionnaire. A descriptive analysis was conducted and regression models were constructed to identify factors influencing the number of drugs provided and the types of drugs prescribed. RESULTS: There were 1281 (80.1 %) patients who received a drug prescription after visiting a doctor at PHC level. 16.2 % of them had five or more drugs prescribed concomitantly. The number of drugs prescribed to patients ranged from 0 to 8 and was statistically different across regions (RRS region =3.3; Khatlon region = 3.1; p = 0.05), after adjusting for age and sex. In 31.1 % of cases, prescriptions included an intra-venous (IV) injection; in 45.6 % of cases, a non-IV injection; in 52.9 % of cases, an antibiotic; and in 61.0 % of cases, vitamins. Patients suffering from a respiratory disease had higher odds of being prescribed an IV injection and antibiotics. Vitamins were widely prescribed across all diseases. In 94.5 % of cases, the patients interviewed procured at least one of the prescribed drugs. Among those who received a prescription, 2.0 % were not able to procure at least one drug due to a lack of money. In 94.9 % of cases, respondents reported purchasing drugs in private pharmacies. Median expenditures for drugs procured following consultation were 45 TS (US$ 6.9) corresponding to 77.6 % of total expenditures related to the visit (58 TS, US$ 8.8). CONCLUSIONS: In a context where OPE are important, drugs represent an important income source for health service providers. Such a situation does not favour rational prescribing nor efficient service delivery, and is potentially harmful for patients. In particular, the economic ramifications cause high levels of expenditure for patients and households with detrimental, knock-on effects in the more vulnerable segments of the population. PMID- 27716268 TI - Perceived effective and feasible strategies to promote healthy eating in young children: focus groups with parents, family child care providers and daycare assistants. AB - BACKGROUND: The aim of the current study is to identify strategies to promote healthy eating in young children that can be applied by caregivers, based on their own perceptions of effectiveness and feasibility. Whereas previous research mainly focused on parental influences on children's eating behavior, the growing role of other caregivers in the upbringing of children can no longer be denied. METHODS: Four focus groups were conducted with three types of caregivers of post weaning children under 6 years old: parents (n = 14), family child care providers (n = 9), and daycare assistants (n = 10). The audiotaped focus group discussions were transcribed and imported into Nvivo 10.0 for thematic analysis. The behaviors put forward by the caregivers were categorized within three broad dimensions: global influences, general behaviors, and specific feeding practices. RESULTS: Perceived effective strategies to promote healthy eating behavior in children included rewards, verbal encouragement, a taste-rule, sensory sensations, involvement, variation, modeling, repeated exposure, and a peaceful atmosphere. Participants mainly disagreed on the perceived feasibility of each strategy, which largely depended on the characteristics of the caregiving setting (e.g. infrastructure, policy). CONCLUSIONS: Based on former research and the current results, an intervention to promote healthy eating behaviors in young children should be adapted to the caregiving setting or focus on specific feeding practices, since these involve simple behaviors that are not hindered by the limitations of the caregiving setting. Due to various misconceptions regarding health-promoting strategies, clear instructions about when and how to use these strategies are necessary. PMID- 27716269 TI - User involvement and experiential knowledge in interprofessional rehabilitation: a grounded theory study. AB - BACKGROUND: User involvement is increasingly important in developing relevant health care services. The aim of this study was to contribute to a deeper understanding of user involvement and patients' experiential knowledge as recognized and incorporated into clinical practice by rehabilitation professionals. METHODS: A qualitative design using a grounded theory approach was applied. Data were collected by observations of the interprofessional meetings at two rehabilitation units treating patients with traumatic brain injury and multiple trauma and by individual semi-structured interviews with rehabilitation professionals. RESULTS: The professionals recognized and incorporated user involvement into clinical practice as formal or authentic. Formal user involvement was sometimes considered pro forma. Incorporating patient' experiential knowledge was considered a part of authentic user involvement. Possible gaps between the patients' experiential knowledge and professional expertise were recognized. Challenges included dealing with 'artifacts', sources of information external to the patients' own experiences, and addressing the patients' possibly reduced insight due to trauma. CONCLUSION: Patients' experiential knowledge was recognized as an essential component of the professionals' knowledge base. The professionals considered user involvement and patients' experiential knowledge as part of their clinical practice. Implementation of user involvement and contribution of patients' experiential knowledge could be improved by understanding the issues raised in practice, such as possible negative consequences of user involvement in form of burdening or disempowering the patients. A better understanding of the characteristics and measures of user involvement is necessary in order to be able to offer its full benefits for both the patients and the professionals. PMID- 27716267 TI - Economic evaluation of treatments for patients with localized prostate cancer in Europe: a systematic review. AB - BACKGROUND: Our objective was to assess the efficiency of treatments in patients with localized prostate cancer, by synthesizing available evidence from European economic evaluations through systematic review. METHODS: Articles published 2000 2015 were searched in MEDLINE, EMBASE and NHS EED (Prospero protocol CRD42015022063). Two authors independently selected studies for inclusion and extracted the data. A third reviewer resolved discrepancies. We included European economic evaluations or cost comparison studies, of any modality of surgery or radiotherapy treatments, regardless the comparator/s. Drummond's Checklist was used for quality assessment. RESULTS: After reviewing 8,789 titles, 13 European eligible studies were included: eight cost-utility, two cost-effectiveness, one cost-minimization, and two cost-comparison analyses. Of them, five compared interventions with expectant management, four contrasted robotic with non robotic assisted surgery, three assessed new modalities of radiotherapy, and three compared radical prostatectomy with brachytherapy. All but two studies scored >=8 in the quality checklist. Considering scenario and comparator, three interventions were qualified as dominant strategies (active surveillance, robotic assisted surgery and IMRT), and six were cost-effective (radical prostatectomy, robotic-assisted surgery, IMRT, proton therapy, brachytherapy, and 3DCRT). However, QALY gains in most of them were small. For interventions considered as dominant strategies, QALY gain was 0.013 for active surveillance over radical prostatectomy; and 0.007 for robotic-assisted over non-robotic techniques. The highest QALY gains were 0.57-0.86 for radical prostatectomy vs watchful waiting, and 0.72 for brachytherapy vs conventional radiotherapy. CONCLUSIONS: Currently, relevant treatment alternatives for localized prostate cancer are scarcely evaluated in Europe. Very limited available evidence supports the cost effectiveness of radical prostatectomy over watchful waiting, brachytherapy over radical prostatectomy, and new treatment modalities over traditional procedures. Relevant disparities were detected among studies, mainly based on effectiveness. These apparently contradictory results may be reflecting the difficulty of interpreting small differences between treatments regarding QALY gains. PMID- 27716271 TI - Possibly preventable cardiac arrest in a morbidly obese patient - a comment on the 2015 ERC guidelines. AB - BACKGROUND: The incidence of overweight and obesity has been steadily on the rise and has reached epidemic proportions in various countries and this represents a well-known major health problem. Nevertheless, current guidelines for resuscitation do not include special sequences of action in this subset of patients. The aim of this letter is to bring this controversy into focus and to suggest alterations of the known standard cardiopulmonary resuscitation in the obese. CASE PRESENTATION: An obese patient weighing 272 kg fell to the floor, afterwards being unable to get up again. Thus, emergency services were called for assistance. There were no signs or symptoms signifying that the person had been harmed in consequence of the fall. Only when brought into a supine position the patient suffered an immediate cardiac arrest. Cardiopulmonary resuscitation was performed but there was no return of a stable spontaneous circulation until the patient was brought into a full lateral position. In spite of immediate emergency care the patient ultimately suffered a lethal hypoxic brain damage. CONCLUSION: A full lateral position should be considered in obese patients having a cardiac arrest as it might help to re-establish stable circulatory conditions. PMID- 27716270 TI - The antidepressant-like effects of pioglitazone in a chronic mild stress mouse model are associated with PPARgamma-mediated alteration of microglial activation phenotypes. AB - BACKGROUND: Discoveries that microglia-mediated neuroinflammation is involved in the pathological process of depression provided a new strategy for novel antidepressant therapy. Peroxisome proliferator-activated receptor gamma (PPARgamma) is a nuclear receptor regulating inflammation and microglial polarization and, therefore, a potential target for resolving depressive disorders. Our hypothesis was that antidepressant effects could be achieved through anti-inflammatory and neuroprotective activities by PPARgamma-dependent microglia-modulating agents. METHODS: Chronic mild stress (CMS) treatment was performed on C57BL/6 mice for 6 weeks. After 3 weeks with the CMS procedure, depressive-like behaviors were evaluated by sucrose preference (SP), tail suspension test (TST), forced swimming test (FST), and locomotor activity. Pioglitazone was administered intragastrically once per day for 3 weeks at different doses. Neuroinflammatory cytokines were determined by real time-PCR (RT PCR), enzyme-linked immunosorbent assay (ELISA), and western blot. The activated microglial state was confirmed by immunohistochemistry. N9 microglial cells were subjected to lipopolysaccharide, pioglitazone, and GW9662 to discuss the phenotype of activated microglia by RT-PCR, ELISA, and western blot. RESULTS: It was demonstrated that the PPARgamma agonist pioglitazone (2.5 mg/kg) ameliorated depression-like behaviors in CMS-treated mice, as indicated by body weight (BW), the SP test, the FST, and the TST. The amelioration of the depression was blocked by the PPARgamma antagonist GW9662. The expression of M1 markers (IL-1beta, IL-6, TNFalpha, iNOS, and CCL2) increased, and the gene expression of M2 markers (Ym1, Arg1, IL-4, IL-10, and TGFbeta) decreased in the hippocampus of the stress treated mice. Pioglitazone significantly inhibited the increased numbers and morphological alterations of microglia in the hippocampus, reduced the elevated expression of microglial M1 markers, and increased the downgraded expression of microglial M2 markers in C57BL/6 mice exposed to CMS. In an in vitro experiment, pioglitazone reversed the imbalance of M1 and M2 inflammatory cytokines, which is correlated with the inhibition of nuclear factor kB activation and is expressed in LPS-stimulated N9 microglial cells. CONCLUSIONS: We showed that pioglitazone administration induce the neuroprotective phenotype of microglia and ameliorate depression-like behaviors in CMS-treated C57BL/6 mice. These data suggested that the microglia-modulating agent pioglitazone present a beneficial choice for depression. PMID- 27716272 TI - The histone deacetylase inhibitor trichostatin a decreases lymphangiogenesis by inducing apoptosis and cell cycle arrest via p21-dependent pathways. AB - BACKGROUND: The formation of new lymphatic vessels provides an additional route for tumour cells to metastasize. Therefore, inhibiting lymphangiogenesis represents an interesting target in cancer therapy. First evidence suggests that histone deacetylase inhibitors (HDACi) may mediate part of their antitumor effects by interfering with lymphangiogenesis. However, the underlying mechanisms of HDACi induced anti-lymphangiogenic properties are not fully investigated so far and in part remain unknown. METHODS: Human lymphatic endothelial cells (LEC) were cultured in vitro and treated with or without HDACi. Effects of HDACi on proliferation and cell cycle progress were analysed by BrdU assay and flow cytometry. Apoptosis was measured by quantifying mono- and oligonucleosomes in the cytoplasmic fraction of cell lysates. In vitro lymphangiogenesis was investigated using the Matrigel short term lymphangiogenesis assay. The effects of TSA on cell cycle regulatory proteins and apoptosis-related proteins were examined by western blotting, immunofluorescence staining and semi-quantitative RT-PCR. Protein- and mRNA half-life of p21 were analysed by western blotting and quantitative RT-PCR. The activity of the p21 promoter was determined using a dual luciferase assay and DNA-binding activity of Sp1/3 was investigated using EMSA. Furthermore, siRNA assays were performed to analyse the role of p21 and p53 on TSA-mediated anti-lymphangiogenic effects. RESULTS: We found that HDACi inhibited cell proliferation and that the pan-HDACi TSA induced G0/G1 arrest in LEC. Cell cycle arrest was accompanied by up-regulation of p21, p27 and p53. Additionally, we observed that p21 protein accumulated in cellular nuclei after treatment with TSA. Moreover, we found that p21 mRNA was significantly up-regulated by TSA, while the protein and mRNA half-life remained largely unaffected. The promoter activity of p21 was enhanced by TSA indicating a transcriptional mechanism. Subsequent EMSA analyses showed increased constitutive Sp1/3-dependent DNA binding in response to HDACi. We demonstrated that p53 was not required for TSA induced p21 expression and growth inhibition of LECs. Interestingly, siRNA mediated p21 depletion almost completely reversed the anti-proliferative effects of TSA in LEC. In addition, TSA induced apoptosis by cytochrome c release contributed to activating caspases-9, -7 and -3 and downregulating the anti apoptotic proteins cIAP-1 and -2. CONCLUSIONS: In conclusion, we demonstrate that TSA - a pan-HDACi - has distinct anti-lymphangiogenic effects in primary human lymphatic endothelial cells by activating intrinsic apoptotic pathway and cell cycle arrest via p21-dependent pathways. PMID- 27716273 TI - A clinical combined gadobutrol bolus and slow infusion protocol enabling angiography, inversion recovery whole heart, and late gadolinium enhancement imaging in a single study. AB - BACKGROUND: The use of gadolinium contrast agents in cardiovascular magnetic resonance is well-established and serves to improve both vascular imaging as well as enable late gadolinium enhancement (LGE) imaging for tissue characterization. Currently, gadofosveset trisodium, an intravascular contrast agent, combined with a three-dimensional inversion recovery balanced steady state free precession (3D IR bSSFP) sequence, is commonly used in pediatric cardiac imaging and yields excellent vascular imaging, but cannot be used for late gadolinium enhancement. Gadofosveset use remains limited in clinical practice, and manufacture was recently halted, thus an alternative is needed to allow 3D IR bSSFP and LGE in the same study. METHODS: Here we propose a protocol to give a bolus of 0.1 mL/kg = 0.1 mmol/kg gadobutrol (GADAVIST/GADOVIST) for time-resolved magnetic resonance angiography (MRA). Subsequently, 0.1 mmol/kg is diluted up to 5 or 7.5 mL with saline and then loaded into intravenous tubing connected to the patient. A 0.5 mL short bolus is infused, then a slow infusion is given at 0.02 or 0.03 mL/s. Image navigated (iNAV) 3D IR bSSFP imaging is initiated 45-60 s after the initiation of the infusion, with a total image acquisition time of ~5 min. If necessary, LGE imaging using phase sensitive inversion recovery reconstruction (PSIR) is performed at 10 min after the infusion is initiated. RESULTS: We have successfully performed the above protocol with good image quality on 10 patients with both time-resolved MRA and 3D IR bSSFP iNAV imaging. Our initial attempts to use pencil beam respiratory navigation failed due to signal labeling in the liver by the navigator. We have also performed 2D PSIR LGE successfully, with both LGE positive and LGE negative results. CONCLUSION: A bolus of gadobutrol, followed later by a slow infusion, allows time-resolved MRA, 3D IR bSSFP using the iNAV navigation technique, and LGE imaging, all in a single study with a single contrast agent.

AB - Cardiovascular disease (CVD) is one of the most common diabetes-associated complications, as well as a leading cause for death in type 2 diabetes patients (T2D). Despite the well-known correlation between the two, up until the 2008 FDA industry guidance for licensing of new anti-hyperglycemic drugs, which required an investigation of cardiovascular outcomes (CVO) of glucose-lowering agents, only a few studies had looked into the relationship between glucose lowering drugs and cardiovascular (CV) risk. Thereafter, CVOT design has focused on non inferiority short-term studies on high-risk patient populations aiming at capturing CV safety issues. Despite the wealth of information and useful data provided by CVOTs, this approach still suffers from certain limitations. The present review will condense the main results of the most recently completed CVOTs, reflect on the lessons learned, discuss on the issues presented by current CVOT design and offer some suggestions for improvement. PMID- 27716275 TI - Enhancing implementation science by applying best principles of systems science. AB - BACKGROUND: Implementation science holds promise for better ensuring that research is translated into evidence-based policy and practice, but interventions often fail or even worsen the problems they are intended to solve due to a lack of understanding of real world structures and dynamic complexity. While systems science alone cannot possibly solve the major challenges in public health, systems-based approaches may contribute to changing the language and methods for conceptualising and acting within complex systems. The overarching goal of this paper is to improve the modelling used in dissemination and implementation research by applying best principles of systems science. DISCUSSION: Best principles, as distinct from the more customary term 'best practices', are used to underscore the need to extract the core issues from the context in which they are embedded in order to better ensure that they are transferable across settings. Toward meaningfully grappling with the complex and challenging problems faced in adopting and integrating evidence-based health interventions and changing practice patterns within specific settings, we propose and illustrate four best principles derived from our systems science experience: (1) model the problem, not the system; (2) pay attention to what is important, not just what is quantifiable; (3) leverage the utility of models as boundary objects; and (4) adopt a portfolio approach to model building. To improve our mental models of the real world, system scientists have created methodologies such as system dynamics, agent-based modelling, geographic information science and social network simulation. To understand dynamic complexity, we need the ability to simulate. Otherwise, our understanding will be limited. The practice of dynamic systems modelling, as discussed herein, is the art and science of linking system structure to behaviour for the purpose of changing structure to improve behaviour. A useful computer model creates a knowledge repository and a virtual library for internally consistent exploration of alternative assumptions. CONCLUSION: Among the benefits of systems modelling are iterative practice, participatory potential and possibility thinking. We trust that the best principles proposed here will resonate with implementation scientists; applying them to the modelling process may abet the translation of research into effective policy and practice. PMID- 27716276 TI - Elevations in growth hormone and glucagon-like peptide-2 levels on admission are associated with increased mortality in trauma patients. AB - BACKGROUND: Burn and trauma patients present a clinical challenge due to metabolic derangements and hypermetabolism that result in a prolonged catabolic state with impaired healing and secondary complications, including ventilator dependence. Previous work has shown that circulating levels of growth hormone (GH) are predictive of mortality in critically ill adults, but few studies have examined the prognostic potential of GH levels in adult trauma patients. METHODS: To investigate the utility of GH and other endocrine responses in the prediction of outcomes, we conducted a prospective, observational study of adult burn and trauma patients. We evaluated the serum concentration of GH, insulin-like growth factor 1 (IGF-1), IGF binding protein 3 (IGFBP-3), and glucagon-like peptide-2 (GLP-2) weekly for up to 6 weeks in 36 adult burn and trauma patients admitted between 2010 and 2013. RESULTS: Non-survivors had significantly higher levels of GH and GLP-2 on admission than survivors. DISCUSSION: This study demonstrates that GH has potential as a predictor of mortality in critically ill trauma and burn patients. Future studies will focus on not only the role of GH, but also GLP 2, which was shown to correlate with mortality in this study with a goal of offering early, targeted therapeutic interventions aimed at decreasing mortality in the critically injured. CONCLUSIONS: GH and GLP-2 may have clinical utility for outcome prediction in adult trauma patients. PMID- 27716277 TI - Array-CGH diagnosis in ovarian failure: identification of new molecular actors for ovarian physiology. AB - BACKGROUND: Ovarian failure (OF) is considered premature if it occurs before the age of 40. This study investigates the genetic aetiology underlying OF in women under the age of 40 years. METHODS: We conducted an experimental prospective study performing all genome microarrays in 60 patients younger than 40 years presenting an OF revealed by a decrease of circulating Anti-Mullerian Hormone (AMH) and leading to an oocyte donation program. RESULTS: We identified nine significant copy number variations (CNVs) including candidate genes potentially implicated in reproductive function. These genes are principally involved in cell division and chromosome segregation (SYCE1, CLASP1, CENP-A, CDC16), in ciliary development and/or function (RSPH1, KIF24), are linked with known gonadal genes or expressed in female genital tract (CSMD1, SEMA6D, KIAA1324). CONCLUSIONS: Our data strengthen the idea that microarrays should be used in combination with karyotype for aetiological assessment of patients with OF. This analysis may have a therapeutic impact as the identification of new molecular actors for gonadal development or ovarian physiology is useful for the prediction of an ovarian reserve decline and makes possible preventive fertility preservation. PMID- 27716278 TI - A systematic review on the rotational thrombelastometry (ROTEM(r)) values for the diagnosis of coagulopathy, prediction and guidance of blood transfusion and prediction of mortality in trauma patients. AB - INTRODUCTION: Viscoelastic assays have been promoted as an improvement over traditional coagulation tests in the management of trauma patients. Rotational thromboelastometry (ROTEM(r)) has been used to diagnose coagulopathy and guide hemostatic therapy in trauma. This systematic review of clinical studies in trauma investigates the ROTEM(r) parameters thresholds used for the diagnosing coagulopathy, predicting and guiding transfusion and predicting mortality. METHODS: Systematic literature search was performed using MEDLINE, EMBASE and Cochrane databases. We included studies without restricting year of publication, language or geographic location. Original studies reporting the thresholds of ROTEM(r) parameters in the diagnosis or management of coagulopathy in trauma patients were included. Data on patient demographics, measures of coagulopathy, transfusion and mortality were extracted. We reported our findings according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Quality assessment and risk of bias were performed using Newcastle Ottawa Scale (NOS) and the quality assessment of diagnostic accuracy studies (QUADAS-2) tools, respectively. RESULTS: A total of 13 observational studies involving 2835 adult trauma patients met the inclusion criteria. Nine studies were prospective and four were retrospective. There were no randomized controlled trials. The quality of the included studies was moderate (mean NOS 5.92, standard deviation 0.26). Using QUADAS-2, only 1 study (7.6 %) had low risk of bias in all domains, and 9 studies (69.2 %) had low risk of applicability concerns. Outcomes from 13 studies were grouped into three categories: diagnosis of coagulopathy (n = 10), prediction of massive transfusion or transfusion guidance (n = 6) and prediction of mortality (n = 6). Overall, specific ROTEM(r) parameters measured (clot amplitude and lysis) in the extrinsically activated test (EXTEM) and the fibrin-based extrinsically activated test (FIBTEM) were consistently associated with the diagnosis of coagulopathy, increased risk of bleeding and massive transfusion, and prediction of mortality. Presence of hyperfibrinolysis by ROTEM(r) was associated with increased mortality. CONCLUSIONS: Most of the evidence indicates that abnormal EXTEM and FIBTEM clot amplitude (CA5, CA10) or maximal clot firmness (MCF) diagnose coagulopathy, and predict blood transfusion and mortality. The presence of fibrinolysis (abnormal lysis index [LI30] or maximum lysis [ML]) was also associated with mortality. ROTEM(r) thus, may be of value in the early management of trauma patients. PMID- 27716279 TI - Adapting a weight management tool for Latina women: a usability study of the Veteran Health Administration's MOVE!23 tool. AB - BACKGROUND: Obesity disproportionately affects Latina women, but few targeted, technology-assisted interventions that incorporate tailored health information exist for this population. The Veterans Health Administration (VHA) uses an online weight management tool (MOVE!23) which is publicly available, but was not designed for use in non-VHA populations. METHODS: We conducted a qualitative study to determine how interactions between the tool and other contextual elements impacted task performance when the target Latina users interacted with MOVE!23. We sought to identify and classify specific facilitators and barriers that might inform design changes to the tool and its context of use, and in turn promote usability. Six English-speaking, adult Latinas were recruited from an inner city primary care clinic and a nursing program at a local university in the United States to engage in a "Think-Aloud" protocol while using MOVE!23. Sessions were recorded, transcribed, and coded to identify interactions between four factors that contribute to usability (Tool, Task, User, Context). RESULTS: Five themes influencing usability were identified: Technical Ability and Technology Preferences; Language Confusion and Ambiguity; Supportive Tool Design and Facilitator Guidance; Relevant Examples; and Personal Experience. Features of the tool, task, and other contextual factors failed to fully support participants at times, impeding task completion. Participants interacted with the tool more readily when its language was familiar and content was personally relevant. When faced with ambiguity and uncertainty, they relied on the tool's visual cues and examples, actively sought relevant personal experiences, and/or requested facilitator support. CONCLUSIONS: The ability of our participants to successfully use the tool was influenced by the interaction of individual characteristics with those of the tool and other contextual factors. We identified both tool-specific and context-related changes that could overcome barriers to the use of MOVE!23 among Latinas. Several general considerations for the design of eHealth tools are noted. PMID- 27716280 TI - Rab-mediated vesicle trafficking in cancer. AB - A large group of small Rab GTPases which mediate secretory and endosomal membrane transport, as well as autophagosome biogenesis, are essential components of vesicle trafficking machinery. Specific Rab protein together with the cognate effectors coordinates the dynamics of trafficking pathway and determines the cargo proteins destination. Functional impairments of Rab proteins by mutations or post-translational modifications disrupting the regulatory network of vesicle trafficking have been implicated in tumorigenesis. Therefore, the vesicle transport regulators play essential roles in the mediation of cancer cell biology, including uncontrolled cell growth, invasion and metastasis. The context dependent role of the same Rab to act as either an oncoprotein or tumor suppressor in different cancers is found. Such discrepancies may be due in part to the interaction of specific Rab protein with different effectors or cargos in various tumors. Here, we review recent advances in the roles of Rab GTPases in communicating with other effectors in tumor progression. In this review, we also emphasize dysregulation of Rab-mediated membrane delivery shifting normal cell behaviors toward malignancy. Thus, recovery of the dysregulated vesicle trafficking systems in cancer cells may provide future directions for potential strategy to restrain tumor progression. PMID- 27716281 TI - Glycine N-methyltransferase deficiency in female mice impairs insulin signaling and promotes gluconeogenesis by modulating the PI3K/Akt pathway in the liver. AB - BACKGROUND: Glycine N-methyltransferase (GNMT) is abundantly expressed in the normal liver but is down-regulated in liver cancer tissues. GNMT knockout (Gnmt-/ ) mice can spontaneously develop chronic hepatitis, fatty liver, and liver cancer. We previously demonstrated that hepatic GNMT is decreased in high-fat diet-induced type 2 diabetes mellitus, but its contribution to metabolic syndrome is unclear. Here we show that GNMT modulates key aspects of metabolic syndrome in mice. METHODS: Eleven-week-old Gnmt-/- and wild-type (WT) mice with a C57BL/6 genetic background were used in this study. The metabolic defects of GNMT deficiency were measured by glucose and insulin tolerance tests, lipid homeostasis, gluconeogenesis, and insulin signaling. RESULTS: Gnmt-/- mice, especially females, exhibited glucose intolerance and insulin resistance. However, their body fat and lean mass, food and water intakes, and energy expenditure did not differ from those of WT mice. In addition, glucose-stimulated insulin secretion and insulin-stimulated glucagon secretion were normal in the serum and pancreatic islets of Gnmt-/- mice. Importantly, we found that GNMT deficiency increased lipogenesis and triglycerides in the liver. The elevated triglycerides disrupted the ability of insulin to induce Akt and S6 ribosomal protein phosphorylation, and then triggered insulin resistance and gluconeogenesis in female Gnmt-/- mice. CONCLUSIONS: Our data indicate that hepatic GNMT regulates lipid and glucose homeostasis, and provide insight into the development of insulin resistance through modulating the PI3K/Akt pathway. PMID- 27716282 TI - Spinal cord injury induces astroglial conversion towards neuronal lineage. AB - BACKGROUND: Neurons have intrinsic capability to regenerate after lesion, though not spontaneously. Spinal cord injury (SCI) causes permanent neurological impairments partly due to formation of a glial scar that is composed of astrocytes and microglia. Astrocytes play both beneficial and detrimental roles on axonal re-growth, however, their precise role after SCI is currently under debate. METHODS: We analyzed molecular changes in astrocytes at multiple stages after two SCI severities using cell-specific transcriptomic analyses. RESULTS: We demonstrate that astrocyte response after injury depends on both time after injury and lesion severity. We then establish that injury induces an autologous astroglial transdifferentiation where over 10 % of astrocytes express classical neuronal progenitor markers including betaIII-tubulin and doublecortin with typical immature neuronal morphology. Lineage tracing confirmed that the origin of these astrocytes is resident mature, rather than newly formed astrocytes. Astrocyte-derived neuronal progenitors subsequently express GABAergic, but not glutamatergic-specific markers. Furthermore, we have identified the neural stem cell marker fibroblast growth factor receptor 4 (Fgfr4) as a potential autologous modulator of astrocytic transdifferentiation following SCI. Finally, we establish that astroglial transdifferentiation into neuronal progenitors starts as early as 72 h and continues to a lower degrees up to 6 weeks post-lesion. CONCLUSION: We thus demonstrate for the first time autologous injury-induced astroglial conversion towards neuronal lineage that may represent a therapeutic strategy to replace neuronal loss and improve functional outcomes after central nervous system injury. PMID- 27716283 TI - Patient-reported outcomes in transition from high-dose U-100 insulin to human regular U-500 insulin in severely insulin-resistant patients with type 2 diabetes: analysis of a randomized clinical trial. AB - BACKGROUND: Initiation and titration of human regular U-500 insulin (U-500R) with a dosing algorithm of either thrice daily (TID) or twice daily (BID) improved glycemic control with fewer injections in patients with type 2 diabetes treated with high-dose, high-volume U-100 insulin. The objective of this analysis was to compare patient-reported outcomes between U-500R TID and BID treatment groups in this titration-to-target randomized, clinical trial. METHODS: In this 24-week, open-label, parallel trial, 325 patients were randomized to TID (n = 162) or BID (n = 163) U-500R after a 4-week lead-in period (screening). The Treatment Related Impact Measure-Diabetes (TRIM-D) and EQ-5D-5L questionnaires were administered at screening, baseline/randomization, and endpoint (24 weeks). The Visual Analog Scale-Injection Site Pain (VAS-ISP) was assessed at baseline/randomization, 12 weeks, and endpoint. RESULTS: The TRIM-D showed statistically significant improvements in overall scores from baseline to endpoint for both BID and TID groups, most domains in the TID group, and all domains in the BID group. The BID group achieved better scores than the TID patients in overall and in treatment burden, daily life, and compliance domains (p < .05). EQ-5D-5L index scores showed no statistically significant differences for TID and BID groups (and no differences between TID and BID groups) from baseline to endpoint. VAS-ISP scores improved for both treatment groups (-5.60 TID; -6.47 BID; p < .05 for both) from baseline to endpoint. CONCLUSIONS: U500 can be successfully titrated for improved glycemic control using BID and TID regimens with diabetes-specific Patient Reported Outcomes showing improvements in both arms; however, BID had better scores than TID in overall, treatment burden, daily life, and compliance domains. TRIAL REGISTRATION: These secondary analyses are based on the study first received January 22, 2013 and reported in Clinical Trial Registry No.: NCT01774968 . PMID- 27716285 TI - Safety, pharmacokinetics, and antitumor properties of anlotinib, an oral multi target tyrosine kinase inhibitor, in patients with advanced refractory solid tumors. AB - BACKGROUND: Anlotinib is a novel multi-target tyrosine kinase inhibitor that is designed to primarily inhibit VEGFR2/3, FGFR1-4, PDGFR alpha/beta, c-Kit, and Ret. We aimed to evaluate the safety, pharmacokinetics, and antitumor activity of anlotinib in patients with advanced refractory solid tumors. METHODS: Anlotinib (5-16 mg) was orally administered in patients with solid tumor once a day on two schedules: (1) four consecutive weeks (4/0) or (2) 2-week on/1-week off (2/1). Pharmacokinetic sampling was performed in all patients. Twenty-one patients were further enrolled in an expanded cohort study on the recommended dose and schedule. Preliminary tumor response was also assessed. RESULTS: On the 4/0 schedule, dose-limiting toxicity (DLT) was grade 3 hypertension at 10 mg. On the 2/1 schedule, DLT was grade 3 hypertension and grade 3 fatigue at 16 mg. Pharmacokinetic assessment indicated that anlotinib had long elimination half lives and significant accumulation during multiple oral doses. The 2/1 schedule was selected, with 12 mg once daily as the maximum tolerated dose for the expanding study. Twenty of the 21 patients (with colon adenocarcinoma, non-small cell lung cancer, renal clear cell cancer, medullary thyroid carcinoma, and soft tissue sarcoma) were assessable for antitumor activity of anlotinib: 3 patients had partial response, 14 patients had stable disease including 12 tumor burden shrinkage, and 3 had disease progression. The main serious adverse effects were hypertension, triglyceride elevation, hand-foot skin reaction, and lipase elevation. CONCLUSIONS: At the dose of 12 mg once daily at the 2/1 schedule, anlotinib displayed manageable toxicity, long circulation, and broad-spectrum antitumor potential, justifying the conduct of further studies. PMID- 27716284 TI - Production of lipopeptide biosurfactants by Bacillus atrophaeus 5-2a and their potential use in microbial enhanced oil recovery. AB - BACKGROUND: Lipopeptides are known as promising microbial surfactants and have been successfully used in enhancing oil recovery in extreme environmental conditions. A biosurfactant-producing strain, Bacillus atrophaeus 5-2a, was recently isolated from an oil-contaminated soil in the Ansai oilfield, Northwest China. In this study, we evaluated the crude oil removal efficiency of lipopeptide biosurfactants produced by B. atrophaeus 5-2a and their feasibility for use in microbial enhanced oil recovery. RESULTS: The production of biosurfactants by B. atrophaeus 5-2a was tested in culture media containing eight carbon sources and nitrogen sources. The production of a crude biosurfactant was 0.77 g L-1 and its surface tension was 26.52 +/- 0.057 mN m-1 in a basal medium containing brown sugar (carbon source) and urea (nitrogen source). The biosurfactants produced by the strain 5-2a demonstrated excellent oil spreading activity and created a stable emulsion with paraffin oil. The stability of the biosurfactants was assessed under a wide range of environmental conditions, including temperature (up to 120 degrees C), pH (2-13), and salinity (0-50 %, w/v). The biosurfactants were found to retain surface-active properties under the extreme conditions. Additionally, the biosurfactants were successful in a test to simulate microbial enhanced oil recovery, removing 90.0 and 93.9 % of crude oil adsorbed on sand and filter paper, respectively. Fourier transform infrared spectroscopy showed that the biosurfactants were a mixture of lipopeptides, which are powerful biosurfactants commonly produced by Bacillus species. CONCLUSIONS: The study highlights the usefulness of optimization of carbon and nitrogen sources and their effects on the biosurfactants production and further emphasizes on the potential of lipopeptide biosurfactants produced by B. atrophaeus 5-2a for crude oil removal. The favorable properties of the lipopeptide biosurfactants make them good candidates for application in the bioremediation of oil contaminated sites and microbial enhanced oil recovery process. PMID- 27716286 TI - Use of beta-caryophyllene to combat bacterial dental plaque formation in dogs. AB - BACKGROUND: Periodontal disease is a highly prevalent illness that affects many dogs, reaching up to 85 % prevalence in individuals over the age of 4 years. Currently the drug of choice for combating the formation of dental plaque in these animals, the etiologic agent of the disease, is chlorhexidine, which has several side effects reported. Thus, surveys are conducted throughout the world in order to identify potential substitutes for antimicrobial therapy and prevention of periodontal disease. The objective of the work was to evaluate the antimicrobial activity of beta-caryophyllene against bacteria from dog's dental plaque in vitro and in vivo. The minimum inhibitory concentration was evaluated by agar microdilution assay, the induction or inhibition of bacterial adherence by sub-inhibitory concentrations in 96-well plates, and reduction of dental plaque formation in mongrel dogs subjected to topical solution with beta caryophyllene for 15 days. RESULTS: Results showed minimum inhibitory concentrations above 100 mg/mL for 25 % of the isolates, 100 mg/mL for 3 %, 50 mg/mL for 25 %, 25 mg/mL for 12 %, 12.5 mg/mL for 19 % and 6.25 mg/mL for 16 %. Bacterial adherences of three Enterococcus sp., one Streptococcus sp., one Haemophilus sp., one Aerococcus sp., one Bacillus sp. and one Lactococcus sp. isolates were inhibited by subinhibitory concentration. One Lactococcus sp., one Bacillus sp. and one Streptococcus sp. were stimulated to adhere by concentrations of 0.19, 1.56 and 0.78 mg/mL, respectively. In vivo assay showed reduction in dental plaque formation by beta-caryophyllene, with final plaque coverage of 23.3 +/- 2.6 % of the total area of the teeth, with significant difference compared with chlorhexidine group (37.5 +/- 3.7 % - p < 0.05) and negative control group (65.5 +/- 2.5 % - p < 0.001). CONCLUSIONS: The results showed that beta-caryophyllene has antimicrobial activity against the proliferation of dog's dental plaque-forming bacteria representing a suitable alternative to the use of chlorhexidine in prophylaxis and treatment of periodontal disease of dogs. PMID- 27716287 TI - Modeling neurological diseases with induced pluripotent cells reprogrammed from immortalized lymphoblastoid cell lines. AB - Patient-specific induced pluripotent stem cells (iPSCs) facilitate understanding of the etiology of diseases, discovery of new drugs and development of novel therapeutic interventions. A frequently used starting source of cells for generating iPSCs has been dermal fibroblasts (DFs) isolated from skin biopsies. However, there are also numerous repositories containing lymphoblastoid B-cell lines (LCLs) generated from a variety of patients. To date, this rich bioresource of LCLs has been underused for generating iPSCs, and its use would greatly expand the range of targeted diseases that could be studied by using patient-specific iPSCs. However, it remains unclear whether patient's LCL-derived iPSCs (LiPSCs) can function as a disease model. Therefore, we generated Parkinson's disease patient-specific LiPSCs and evaluated their utility as tools for modeling neurological diseases. We established iPSCs from two LCL clones, which were derived from a healthy donor and a patient carrying PARK2 mutations, by using existing non-integrating episomal protocols. Whole genome sequencing (WGS) and comparative genomic hybridization (CGH) analyses showed that the appearance of somatic variations in the genomes of the iPSCs did not vary substantially according to the original cell types (LCLs, T-cells and fibroblasts). Furthermore, LiPSCs could be differentiated into functional neurons by using the direct neurosphere conversion method (dNS method), and they showed several Parkinson's disease phenotypes that were similar to those of DF-iPSCs. These data indicate that the global LCL repositories can be used as a resource for generating iPSCs and disease models. Thus, LCLs are the powerful tools for generating iPSCs and modeling neurological diseases. PMID- 27716288 TI - Methylferulate from Tamarix aucheriana inhibits growth and enhances chemosensitivity of human colorectal cancer cells: possible mechanism of action. AB - BACKGROUND: Natural products are valuable sources for anticancer agents. In the present study, methylferulate (MF) was identified for the first time from Tamarix aucheriana. Spectral data were used for identification of MF. The potential of MF to control cell growth, cell cycle, apoptosis, generation of reactive oxygen species (ROS), cancer cell invasion, nuclear factor kappa B (NFkB) DNA-binding activity and proteasomal activities, as well as the enhancement of chemosensitivity in human colorectal cancer cells, were evaluated. The possible molecular mechanism of MF's therapeutic efficacy was also assessed. METHODS: Column chromatography and spectral data were used for isolation and identification of MF. MTT, immunofluorescence, flow cytometry, in vitro invasion, fluoremetry, EIA and Real time qPCR were used to measure antiproliferative, chemo sensitizing effects and other biochemical parameters. RESULTS: MF showed a dose dependent anti-proliferative effect on colorectal cancer cells (IC50 = 1.73 - 1.9 mM) with a nonsignificant cytotoxicity toward normal human fibroblast. Colony formation inhibition (P <= 0.001, 0.0001) confirmed the growth inhibition by MF. MF arrested cell cycle progression in the S and G2/M phases; induced apoptosis and ROS generation; and inhibited NF-kB DNA-binding activity, proteasomal activities and cell invasion in colorectal cancer cells. MF up-regulated cyclin dependent kinase inhibitors (p19 INK4D, p21WAF1/CIP1, p27KIP1), pro-apoptotic gene expression (Bax, Bad, Apaf1, Bid, Bim, Smac) and caspases (caspase 2, 3, 6, 7, 8, 9). Moreover, MF down-regulated cyclin-dependent kinases (Cdk1, Cdk2) and anti-apoptotic gene expression (c-IAP-1, c-IAP-2, Bcl2,FLIP). In addition, MF differentially potentiated the sensitivity of colorectal cancer cells to standard chemotherapeutic drugs. CONCLUSION: MF showed a multifaceted anti-proliferative and chemosensitizing effects. These results suggest the chemotherapeutic and co adjuvant potential of MF. PMID- 27716289 TI - Vitamin D modifies the associations between circulating betatrophin and cardiometabolic risk factors among youths at risk for metabolic syndrome. AB - BACKGROUND: Betatrophin has been recently reported to play a role in glucose homeostasis by inducing beta-cell proliferation in mice. However, studies in human are inconsistent. As a nutritionally-regulated liver-enriched factor, we hypothesize that betatrophin might be regulated by vitamin D, and ignorance of vitamin D status may explain the discrepancy in previous human studies. The aims of this study were to assess the association between circulating betatrophin and glucose homeostasis as well as other cardiometabolic variables in a cohort of youths at risk for metabolic syndrome and test the possible influence of vitamin D status on the association. METHODS: 559 subjects aged 14-28 years were recruited from Beijing children and adolescents metabolic syndrome study. All underwent a 2 h-oral glucose tolerance test. Serum levels of betatrophin, 25 hydroxy-vitamin D as well as adipokines including adiponectin and fibroblast growth factor 21 (FGF21) were measured by immunoassays. The relationships between betatrophin and insulin resistance, beta-cell function, other cardiometabolic variables and vitamin D status were evaluated. RESULTS: Participants in the highest quartile of betatrophin levels had the highest levels of total cholesterol (P < 0.001), triglyceride (P < 0.001) and low-density lipoprotein cholesterol (P < 0.001) and the lowest levels of vitamin D (P = 0.003). After stratification by vitamin D status, betatrophin in subjects with vitamin D deficiency were positively correlated with unfavorable metabolic profiles including high blood pressures, dyslipidemia and hyperglycemia, whereas betatrophin in those with higher vitamin D levels only showed negative association with fasting insulin, 2 h-insulin, and insulin resistance. In addition, adiponectin and FGF21 demonstrated the expected associations with metabolic parameters. CONCLUSIONS: Elevated betatrophin levels were associated with cardiometabolic risk factors in this young population, but the association was largely dependent on vitamin D status. These findings may provide valuable insights in the regulation of betatrophin and help explain the observed discrepancies in literature. PMID- 27716290 TI - Neurofeedback training for alcohol dependence versus treatment as usual: study protocol for a randomized controlled trial. AB - BACKGROUND: Real-time functional magnetic resonance imaging (rtfMRI) is used for neurofeedback training (NFT). Preliminary results suggest that it can help patients to control their symptoms. This study uses rtfMRI NFT for relapse prevention in alcohol dependence. METHODS/DESIGN: Participants are alcohol dependent patients who have completed a detoxification programme within the past 6 months and have remained abstinent. Potential participants are screened for eligibility, and those who are eligible are randomly assigned to the treatment group (receiving rtfMRI NFT in addition to treatment as usual) or the control group (receiving only treatment as usual). Participants in both groups are administered baseline assessments to measure their alcohol consumption and severity of dependence and a variety of psychological and behavioural characteristics that are hypothesised to predict success with rtfMRI NFT. During the following 4 months, experimental participants are given six NFT sessions, and before and after each session various alcohol-related measures are taken. Participants in the control group are given the same measures to coincide with their timing in the experimental group. Eight and 12 months after the baseline assessment, both groups are followed up with a battery of measures. The primary research questions are whether NFT can be used to teach participants to down regulate their brain activation in the presence of alcohol stimuli or to up regulate their brain activation in response to pictures related to healthy goal pursuits, and, if so, whether this translates into reductions in alcohol consumption. The primary outcome measures will be those derived from the functional brain imaging data. We are interested in improvements (i.e., reductions) in participants' alcohol consumption from pretreatment levels, as indicated by three continuous variables, not simply whether or not the person has remained abstinent. The indices of interest are percentage of days abstinent, drinks per drinking day, and percentage of days of heavy drinking. General linear models will be used to compare the NFT group and the control group on these measures. DISCUSSION: Relapse in alcohol dependence is a recurring problem, and the present evaluation of the role of rtfMRI in its treatment holds promise for identifying a way to prevent relapse.

PMID- 27716291 TI - Enzymatic fine-tuning for 2-(6-hydroxynaphthyl) beta-D-xylopyranoside synthesis catalyzed by the recombinant beta-xylosidase BxTW1 from Talaromyces amestolkiae. AB - BACKGROUND: Glycosides are compounds displaying crucial biological roles and plenty of applications. Traditionally, these molecules have been chemically obtained, but its efficient production is limited by the lack of regio- and stereo-selectivity of the chemical synthesis. As an interesting alternative, glycosidases are able to catalyze the formation of glycosides in a process considered green and highly selective. In this study, we report the expression and characterization of a fungal beta-xylosidase in Pichia pastoris. The transglycosylation potential of the enzyme was evaluated and its applicability in the synthesis of a selective anti-proliferative compound demonstrated. RESULTS: The beta-xylosidase BxTW1 from the ascomycete fungus Talaromyces amestolkiae was cloned and expressed in Pichia pastoris GS115. The yeast secreted 8 U/mL of beta xylosidase that was purified by a single step of cation-exchange chromatography. rBxTW1 in its active form is an N-glycosylated dimer of about 200 kDa. The enzyme was biochemically characterized displaying a K m and k cat against p-nitrophenyl beta-D-xylopyranoside of 0.20 mM and 69.3 s-1 respectively, and its maximal activity was achieved at pH 3 and 60 degrees C. The glycan component of rBxTW1 was also analyzed in order to interpret the observed loss of stability and maximum velocity when compared with the native enzyme. A rapid screening of aglycone specificity was performed, revealing a remarkable high number of potential transxylosylation acceptors for rBxTW1. Based on this analysis, the enzyme was successfully tested in the synthesis of 2-(6-hydroxynaphthyl) beta-D xylopyranoside, a well-known selective anti-proliferative compound, enzymatically obtained for the first time. The application of response surface methodology, following a Box-Behnken design, enhanced this production by eightfold, fitting the reaction conditions into a multiparametric model. The naphthyl derivative was purified and its identity confirmed by NMR. CONCLUSIONS: A beta-xylosidase from T. amestolkiae was produced in P. pastoris and purified. The final yields were much higher than those attained for the native protein, although some loss of stability and maximum velocity was observed. rBxTW1 displayed remarkable acceptor versatility in transxylosylation, catalyzing the synthesis of a selective antiproliferative compound, 2-(6-hydroxynaphthyl) beta-D-xylopyranoside. These results evidence the interest of rBxTW1 for transxylosylation of relevant products with biotechnological interest.

AB - BACKGROUND: Respiratory illness is traditionally regarded as the disease of the growing pig, and has historically mainly been associated to bacterial infections with focus on Mycoplasma hyopneumoniae and Actinobacillus pleuropneumoniae. These bacteria still are of great importance, but continuously increasing herd sizes have complicated the scenario and the influence of secondary invaders may have been increased. The aim of this study was to evaluate the presence of A. pleuropneumoniae and M. hyopneumoniae, as well as that of the secondary invaders Pasteurella multocida and Streptococcus suis by serology in four pig herds (A-D) using age segregated rearing systems with high incidences of pleuritic lesions at slaughter. RESULTS: Pleuritic lesions registered at slaughter ranged from 20.5 to 33.1 % in the four herds. In herd A, the levels of serum antibodies to A. pleuropneumoniae exceeded A450 > 1.5, but not to any other microbe searched for. The seroconversion took place early during the fattening period. Similar levels of serum antibodies to A. pleuropneumoniae were also recorded in herd B, with a subsequent increase in levels of antibodies to P. multocida. Pigs seroconverted to both agents during the early phase of the fattening period. In herd C, pigs seroconverted to P. multocida during the early phase of the fattening period and thereafter to A. pleuropneumoniae. In herd D, the levels of antibodies to P. multocida exceeded A450 > 1.0 in absence (A450 < 0.5) of antibodies to A. pleuropneumoniae. The levels of serum antibodies to M. hyopneumoniae and to S. suis remained below A450 < 1.0 in all four herds. Pigs seroconverted to M. hyopneumoniae late during the rearing period (herd B-D), or not at all (herd A). CONCLUSION: Different serological patterns were found in the four herds with high levels of serum antibodies to A. pleuropneumoniae and P. multocida, either alone or in combination with each other. Seroconversion to M. hyopneumoniae late during the rearing period or not at all, confirmed the positive effect of age segregated rearing in preventing or delaying infections with M. hyopneumoniae. The results obtained highlight the necessity of diagnostic investigations to define the true disease pattern in herds with a high incidence of pleuritic lesions.

AB - BACKGROUND: Innovative trial designs are sought to streamline drug development in rare diseases. Basket- and integrated protocol designs are two of these new strategies and have been applied in a handful oncologic trials. We have taken the concept outside the realm of oncology and report about a first-in-human integrated protocol design that facilitates the transition from phase Ia in healthy volunteers to phase Ib in patients with rare complement-mediated disorders driven by the classical pathway. RESULTS: We have been conducting a prospective, double-blind, randomized, placebo-controlled first-in-human study with TNT009, which is a humanized monoclonal antibody directed against the C1s subunit of human complement component C1. The trial consisted of three subparts, including normal healthy volunteers (part one and two) and a single cohort of patients in part three. Patients suffered from various complement-mediated diseases sharing the same pathophysiological mechanism, i.e. bullous pemphigoid, antibody-mediated rejection of organ transplants, cold agglutinin disease and warm autoimmune hemolytic anemia. Primary objective of the trial has been to evaluate the safety and tolerability of TNT009 in humans. CONCLUSIONS: This trial provides probably the first example that basket trials may not be limited to single genetic aberrations, which is overly restrictive, but our trial design demonstrates that pathway specificity is a viable paradigm for defining baskets. This will hopefully serve as a role model that could benefit other innovative drug development programs targeting rare diseases. PMID- 27716295 TI - Association of KCTD10, MVK, and MMAB polymorphisms with dyslipidemia and coronary heart disease in Han Chinese population. AB - BACKGROUND: Several genome-wide association studies have discovered novel loci at chromosome 12q24, which includes mevalonate kinase (MVK), methylmalonic aciduria (cobalamin deficiency) cbIB type (MMAB), and potassium channel tetramerization domain-containing 10 (KCTD10), all of which influence HDL-cholesterol concentrations. However, there are few reports on the associations between these polymorphisms and HDL-C concentrations in Chinese population. This study aimed to evaluate the associations between functional polymorphisms in three genes (MVK, MMAB and KCTD10) and HDL-C concentrations, as well as coronary heart disease (CHD) susceptibility in Chinese individuals. METHODS: We systematically selected and genotyped 18 potentially functional polymorphisms in MVK, MMAB and KCTD10 by using the TaqMan OpenArray Genotyping System in a Chinese population including 399 dyslipidemia cases, 697 CHD cases and 465 controls. Multivariate logistic regression analyses were performed to estimate the relationship between the genotypes and dyslipidemia, CHD risk with adjustment of relevant confounders. RESULTS: Among six polymorphisms showing significant associations with dyslipidemia, the minor alleles of rs11066782 in KCTD10, rs11613718 in KCTD10 and rs11067233 in MMAB were significantly associated with a decreased risk of CHD (additive model: OR = 0.71, 95 % CI = 0.53-0.97, P = 0.029 for rs11066782; OR = 0.73, 95 % CI = 0.54-0.99, P = 0.044 for rs11613718 and OR = 0.57, 95 % CI = 0.40 0.80, P = 0.001 for rs11067233). Further combined analysis showed that individuals carrying "3-4" favorable alleles presented a 62 % (OR = 0.38, 95 % CI = 0.21-0.66) decreased risk of CHD compared with those carrying "0-2" favorable alleles. CONCLUSIONS: These findings suggest that rs11066782 in KCTD10, rs11613718 in KCTD10 and rs11067233 in MMAB may contribute to the susceptibility of CHD by altering plasma HDL-C levels in Han Chinese. PMID- 27716296 TI - Health inequalities research in India: a review of trends and themes in the literature since the 1990s. AB - BACKGROUND: Research on health inequalities can be instrumental in drawing attention to the health of socioeconomically vulnerable groups in India in the context of rapid economic growth. It can shape the dialogue for public health action, emphasizing the need for greater investments in health, and monitor effectiveness of health programs. Our objective was to examine trends in studies on health inequalities in the last 25 years. METHODS: We conducted a systematic literature review of studies on health inequalities published from 1990. The year, 1990, marked the beginning of economic reforms and liberalization in India. We searched PubMED using key terms to identify 8800 articles between 1990 and 2016; we identified 1,312 final studies for review. Key domains of analysis included measures of equity, health outcomes, populations studied, year of publication, study methodology, study focus (descriptive versus analytical), and location of main author. RESULTS: We found an increase in studies on health inequalities after 2005. About 88 % of the studies utilized quantitative methods for analysis. About 8 % of the studies related to health interventions or programs; the number of intervention studies have been increasing since 2010. A majority of studies were led by authors based in India. Early studies focused on mortality, communicable and non-communicable diseases, and nutrition, while later studies have focused on non-communicable diseases, mental health, risk factors, and injuries. Studies on women and children comprised nearly half of the literature; studies on the youth (15-24 years or as defined by the study) and elderly have been rising. Wealth and income were the most common measures of equity, followed by education and gender. The proportion of studies on wealth, education, region and caste have stayed consistent over time, while studies on gender disparities have been rising. CONCLUSION: In a country as diverse as India with large social inequalities combined with rapid economic growth, research on health inequalities has a special significance for policy. We recommend that studies on health inequalities in the future focus on evaluations of policy and health programs, and on underrepresented health outcomes and populations. PMID- 27716297 TI - A randomised controlled trial of three very brief interventions for physical activity in primary care. AB - BACKGROUND: Very brief interventions (VBIs) for physical activity are promising, but there is uncertainty about their potential effectiveness and cost. We assessed potential efficacy, feasibility, acceptability, and cost of three VBIs in primary care, in order to select the most promising intervention for evaluation in a subsequent large-scale RCT. METHODS: Three hundred and ninety four adults aged 40-74 years were randomised to a Motivational (n = 83), Pedometer (n = 74), or Combined (n = 80) intervention, delivered immediately after a preventative health check in primary care, or control (Health Check only; n = 157). Potential efficacy was measured as the probability of a positive difference between an intervention arm and the control arm in mean physical activity, measured by accelerometry at 4 weeks. RESULTS: For the primary outcome the estimated effect sizes (95 % CI) relative to the Control arm for the Motivational, Pedometer and Combined arms were respectively: +20.3 (-45.0, +85.7), +23.5 (-51.3, +98.3), and -3.1 (-69.3, +63.1) counts per minute. There was a73% probability of a positive effect on physical activity for each of the Motivational and Pedometer VBIs relative to control, but only 46 % for the Combined VBI. Only the Pedometer VBI was deliverable within 5 min. All VBIs were acceptable and low cost. CONCLUSIONS: Based on the four criteria, the Pedometer VBI was selected for evaluation in a large-scale trial. TRIAL REGISTRATION: Current Controlled Trials ISRCTN02863077 . Retrospectively registered 05/10/2012. PMID- 27716298 TI - Collaborative Assessment and Management of Suicidality (CAMS) compared to treatment as usual (TAU) for suicidal patients: study protocol for a randomized controlled trial. AB - BACKGROUND: Collaborative Assessment and Management of Suicidality (CAMS) is a therapeutic framework that appears promising to reduce suicidal ideation and suicidal cognition. CAMS has not previously been evaluated in a standard specialized mental health care setting for patients with suicidal problems in general. In this pragmatic randomized controlled trial (RCT) we will investigate if CAMS is more effective than treatment as usual (TAU) in reducing suicidal thoughts and behaviors. Effects will also be investigated on mental health and symptom relief in general and upon readmissions to inpatient units. METHODS/DESIGN: The study is a multicenter, observer-blinded, superiority, two armed RCT which will include patients from four clinical departments at Vestre Viken Hospital Trust, Norway. We aim to include 100 patients with moderate to strong suicidal problems, as defined by a score of 13 or more on Beck's Scale for Suicide Ideation - Current. Patients are included regardless of diagnosis. Randomization will be performed using a stratified four-block procedure with treatment unit as the stratification variable. The duration of treatment will vary depending on patients' needs and clinical assessments. Patients are interviewed by research staff at four checkpoints: baseline, 2 weeks, 6 months, and 12 months. Central outcome measures are the Beck Scale for Suicide Ideation - Current, Outcome Questionnaire - 45, and Suicide Attempt Self-Injury Count. DISCUSSION: This pragmatic trial is effectuated within the Public Health Care System in Norway, where patients have multiple problems and diagnoses and therapists have a high work load. Results from this trial are highly generalizable to a typical everyday clinical setting, and one should expect similar results if CAMS is implemented in the future as a standard component in specialized mental health care systems.

PMID- 27716299 TI - Perceptions of health managers and professionals about mental health and primary care integration in Rio de Janeiro: a mixed methods study. AB - BACKGROUND: Community-based primary mental health care is recommended in low and middle-income countries. The Brazilian Health System has been restructuring primary care by expanding its Family Health Strategy. Due to mental health problems, psychosocial vulnerability and accessibility, Matrix Support teams are being set up to broaden the professional scope of primary care. This paper aims to analyse the perceptions of health professionals and managers about the integration of primary care and mental health. METHOD: In this mixed-method study 18 health managers and 24 professionals were interviewed from different primary and mental health care services in Rio de Janeiro. A semi-structured survey was conducted with 185 closed questions ranging from 1 to 5 and one open-ended question, to evaluate: access, gateway, trust, family focus, primary mental health interventions, mental health records, mental health problems, team collaboration, integration with community resources and primary mental health education. Two comparisons were made: health managers and professionals' (Mann Whitney non-parametric test) and health managers' perceptions (Kruskall-Wallis non parametric-test) in 4 service designs (General Traditional Outpatients, Mental Health Specialised Outpatients, Psychosocial Community Centre and Family Health Strategy)(SPSS version 17.0). Qualitative data were subjected to Framework Analysis. RESULTS: Firstly, health managers and professionals' perceptions converged in all components, except the health record system. Secondly, managers' perceptions in traditional services contrasted with managers' perceptions in community-based services in components such as mental health interventions and team collaboration, and converged in gateway, trust, record system and primary mental health education. Qualitative data revealed an acceptance of mental health and primary care integration, but a lack of communication between institutions. The Mixed Method demonstrated that interviewees consider mental health and primary care integration as a requirement of the system, while their perceptions and the model of work produced by the institutional culture are inextricably linked. CONCLUSION: There is a gap between health managers' and professionals' understanding of community-based primary mental health care. The integration of different processes of work entails both rethinking workforce actions and institutional support to help make changes. PMID- 27716300 TI - Seasonal rainfall at long-term migratory staging sites is associated with altered carry-over effects in a Palearctic-African migratory bird. AB - BACKGROUND: An understanding of year-round habitat use is essential for determining how carry-over effects shape population dynamics in long-distance migratory songbirds. The recent discovery of long-term migratory staging sites in many species, prior to arrival at final wintering sites, adds complexity to efforts to decipher non-breeding habitat use and connections between sites. We investigated whether habitat conditions during migratory staging carry over to influence great reed warbler (Acrocephalus arundinaceus) body condition at final wintering sites in Zambia. We asked whether the presence/absence and strength of such carry-over effects were modified by contrasting rainfall conditions during 2 years. RESULTS: First, we found that individuals staging in a dry year had higher corticosterone (CORTf) and stable nitrogen isotope values (suggesting higher aridity) than birds staging in a wet year, indicating that regional weather affected staging conditions. Second, we found that carry-over effects from staging habitat conditions (measured via carbon and nitrogen isotopes) to final winter site body condition (measured via scaled mass index and beta hydroxybutyrate) were only present in a dry year, suggesting that environmental factors have consequences for the strength of carry-over effects. Our results also suggest that wet conditions at final winter sites may buffer the effects of poor staging conditions, at least in the short term, since individuals that staged in a dry year had higher scaled mass indices in Zambia than individuals that staged in a wet year. CONCLUSIONS: This study provides a first insight into the connections between long-term migratory staging sites and final wintering sites, and suggests that local environmental factors can modify the strength of carry-over effects for long-distance migratory birds. PMID- 27716302 TI - Back to the basics of ovarian aging: a population-based study on longitudinal anti-Mullerian hormone decline. AB - BACKGROUND: Anti-Mullerian hormone (AMH) is currently used as an ovarian reserve marker for individualized fertility counseling, but very little is known of individual AMH decline in women. This study assessed whether the decline trajectory of AMH is uniform for all women, and whether baseline age-specific AMH levels remain consistently high or low during this trajectory. METHODS: A total of 3326 female participants from the population-based Doetinchem Cohort Study were followed with five visits over a 20-year period. Baseline age was 40 +/- 10 years with a range of 20-59 years. AMH was measured in 12,929 stored plasma samples using the picoAMH assay (AnshLabs). Decline trajectories of AMH were studied with both chronological age and reproductive age, i.e., time to menopause. Multivariable linear mixed effects models characterized the individual AMH decline trajectories. RESULTS: The overall rate of AMH decline accelerated after 40 years of age. Mixed models with varying age-specific AMH levels and decline rates provided the significantly best fit to the data, indicating that the fall in AMH levels over time does not follow a fixed pattern for individual women. AMH levels remained consistent along individual trajectories of age, with an intraclass correlation coefficient (ICC) of 0.87. The ICC of 0.32 for AMH trajectories with time to menopause expressed the large variation in AMH levels at a given time before the menopause. The differences between low and high age specific AMH levels remained distinguishable, but became increasingly smaller with increasing chronological and reproductive age. CONCLUSIONS: This is the first study to characterize individual AMH decline over a long time period and broad age range. The varying AMH decline rates do not support the premise of a uniform AMH decline trajectory. Although age-specific AMH levels remain consistently high or low with increasing age, the converging trajectories and variance of AMH levels at a given time before menopause shed doubt on the added value of AMH to represent individualized reproductive age. PMID- 27716303 TI - Realist trials and the testing of context-mechanism-outcome configurations: a response to Van Belle et al. AB - BACKGROUND: Van Belle et al. argue that our attempt to pursue realist evaluation via a randomised trial will be fruitless because we misunderstand realist ontology (confusing intervention mechanisms with intervention activities and with statistical mediation analyses) and because RCTs cannot comprehensively examine how and why outcome patterns are caused by mechanisms triggered in specific contexts. METHODS: Through further consideration of our trial methods, we explain more fully how we believe complex social interventions work and what realist evaluation should aim to do within a trial. RESULTS: Like other realists, those undertaking realist trials assume that: social interventions provide resources which local actors may draw on in actions that can trigger mechanisms; these mechanisms may interact with contextual factors to generate outcomes; and data in the 'empirical' realm can be used to test hypotheses about mechanisms in the 'real' realm. Whether or not there is sufficient contextual diversity to test such hypotheses is a contingent not a necessary feature of trials. Previous exemplars of realist evaluation have compared empirical data from intervention and control groups to test hypotheses about real mechanisms. There is no inevitable reason why randomised trials should not also be able to do so. Random allocation merely ensures the comparability of such groups without necessarily causing evaluation to lapse from a realist into a 'positivist' or 'post positivist' paradigm. CONCLUSIONS: Realist trials are ontologically and epistemologically plausible. Further work is required to assess whether they are feasible and useful but such work should not be halted on spurious philosophical grounds. PMID- 27716301 TI - Subsidized health insurance coverage of people in the informal sector and vulnerable population groups: trends in institutional design in Asia. AB - BACKGROUND: Many low- and middle-income countries with a social health insurance system face challenges on their road towards universal health coverage (UHC), especially for people in the informal sector and vulnerable population groups or the informally employed. One way to address this is to subsidize their contributions through general government revenue transfers to the health insurance fund. This paper provides an overview of such health financing arrangements in Asian low- and middle-income countries. The purpose is to assess the institutional design features of government subsidized health insurance type arrangements for vulnerable and informally employed population groups and to explore how these features contribute to UHC progress. METHODS: This regional study is based on a literature search to collect country information on the specific institutional design features of such subsidization arrangements and data related to UHC progress indicators, i.e. population coverage, financial protection and access to care. The institutional design analysis focuses on eligibility rules, targeting and enrolment procedures; financing arrangements; the pooling architecture; and benefit entitlements. RESULTS: Such financing arrangements currently exist in 8 countries with a total of 14 subsidization schemes. The most frequent groups covered are the poor, older persons and children. Membership in these arrangements is mostly mandatory as is full subsidization. An integrated pool for both the subsidized and the contributors exists in half of the countries, which is one of the most decisive features for equitable access and financial protection. Nonetheless, in most schemes, utilization rates of the subsidized are higher compared to the uninsured, but still lower compared to insured formal sector employees. Total population coverage rates, as well as a higher share of the subsidized in the total insured population are related with broader eligibility criteria. CONCLUSIONS: Overall, government subsidized health insurance type arrangements can be effective mechanism to help countries progress towards UHC, yet there is potential to improve on institutional design features as well as implementation. PMID- 27716305 TI - Health seeking behavior and use of medicinal plants among the Hamer ethnic group, South Omo zone, southwestern Ethiopia. AB - BACKGROUND: Health seeking behavior of people around the globe is affected by different socio-cultural and economic factors. In Ethiopia, people living in rural areas in particular, are noted for their use of medicinal plants as a major component of their health care option. This study was conducted to document ethnopharmacological information of the Hamer semi-pastoralists ethnic group in southwestern Ethiopia. METHODS: A cross-sectional study was carried out whereby information on demographic characteristics, prevalence of perceived illnesses, factors associated with preference of health care seeking options, medicinal plants used and hoarded as well as some healers' socio-economic characteristics were collected using two sets of semi-structured questionnaires - one for household (HH) heads and the other for traditional healers supplemented by focus group discussions (FGDs). Households were selected using a cluster sampling followed by systematic sampling techniques; whereas healers and FGD participants were purposively selected with the assistance of local leaders and elders from the community. RESULTS: The study revealed that the use of traditional medicine among the Hamer ethnic group is very high. Females preferred traditional medicine more than males. The main reasons for this preference include effectiveness, low cost and ease of availability. Malaria (gebeze) was the most frequently occurring illness in the area identified by all FGD participants. A total of 60 different medicinal plants were reported [34 by HH respondents, 14 by traditional healers and 12 by both]. Fifty-one medicinal plants were fully identified, 3 at generic level and 6 have not yet been identified. CONCLUSION: It can be concluded that traditional medical practices, particularly herbal aspect, is widely used by the Hamer ethnic group, although health seeking behavior of the community is affected by different socio-economic and cultural factors. PMID- 27716304 TI - Appropriate vitamin D loading regimen for patients with advanced lung cancer. AB - BACKGROUND: Most patients attending cancer clinics have hypovitaminosis D. Correcting or preventing this abnormal condition could mitigate the emotional and physical complications of their disease, but clinical trials of vitamin D therapy in this setting are hindered by the unavailability of safe, effective and practical loading dose regimens. METHODS: In this single arm open-label pharmacokinetic trial, outpatients with advanced lung cancer consumed 20,000 IU vitamin D daily with the largest meal of the day for 14 days followed by 10,000 IU per day for a further 7 days. Plasma concentrations of 25-hydroxyvitamin D [25(OH)D], parathyroid hormone, calcium, vitamin C and C-reactive protein were measured on protocol days 0, 14 and 21, and serum vitamin D binding protein (VDBP) concentrations on days 0 and 21. As a secondary objective, preliminary information was obtained regarding clinical effects of rapid vitamin D loading on mood and symptoms by administering appropriate questionnaires two times at baseline and after 14 and 21 days of vitamin D therapy. RESULTS: Of the 91 patients enrolled in the study, 85 % had hypovitaminosis D and 41 % had hypovitaminosis C. Plasma VDBP concentrations were in the normal range. The vitamin D load increased the average plasma 25(OH)D concentration to 116 +/- 34 nmol/L (mean +/- SD); the median concentration was 122 nmol/L (interquartile range 103-134); VDBP concentrations did not change. Final plasma 25(OH)D concentrations were subnormal (<75 nmol/L) for 13 % of the patients and sub target (<120 nmol/L) for 44 % of them. In most cases, subnormal and sub-target 25(OH)D concentrations were attributable to obesity and/or a low baseline 25(OH)D concentration. Mood and symptom scores did not change significantly throughout the 3-week protocol. CONCLUSION: Hypovitaminosis D and C are very common in outpatients with advanced lung cancer. A vitamin D load of 20,000 IU per day for 14 days failed to achieve the target concentration in 44 % of the participants in this trial. These results suggest that a loading dose of 30,000 IU per day for 14 days would be safe and effective for patients who are obese or at risk of severe hypovitaminosis D. The preliminary nature of the study design, and the failure to achieve target 25(OH)D concentrations for a large proportion of the patients, do not allow any firm conclusion about the clinical effects of correcting hypovitaminosis D in this patient population. Nevertheless, no evidence was obtained that partial correction of hypovitaminosis D greatly improved mood, reduced distress or relieved cancer-related symptoms. This trial was registered at clinicaltrials.gov as NCT01631526. PMID- 27716306 TI - Post-incisional ventral hernia repair in patients undergoing chemotherapy: improving outcomes with biological mesh. AB - BACKGROUND: Patients requiring ventral hernia (VH) repair during perioperative chemotherapy have a higher risk for post-operative complications. The aim of the study was to perform a case-controlled analysis in patients undergoing chemotherapy who underwent VH repair using biological mesh or synthetic mesh. METHODS: From January 2013 to December 2015, 32 patients, within 8 weeks from chemotherapy administration, were treated electively for VH repair using a biological mesh (BIOMESH). A control group (CG) receiving chemotherapy within the same time interval and treated with synthetic meshes was selected. There were no differences regarding sex, age, American Society of Anesthesiologists (ASA) score III, BMI, and size of the defect. Morbidity, type of complications, and recurrence rate were investigated and compared between the two groups. RESULTS: In the BIOMESH group, eight patients (25 %) experienced complications. Wound dehiscence occurred in four (12.5 %) patients and was treated conservatively. Only three small seromas not requiring treatment were observed. The CG presented a higher mean Clavien-Dindo complication grade (1.94 +/- 0.44 vs 1.63 +/- 0.52; p = 0.13) and a higher incidence of wound dehiscence (n = 9/32, 28.1 % vs n = 4/32, 12.5 %; p = 0.11). Five patients developed seroma treated by wound drainage. One patient experienced an intra-abdominal collection treated by percutaneous drainage. At the univariate and multivariate analysis use of traditional mesh, BMI and the ASA III were predictive factors of post-operative complications. Two patients (6.3 %) developed a VH recurrence only in the CG. CONCLUSIONS: Biological meshes could be considered a valid option to improve post-operative short-term outcomes in selected high-risk patients undergoing chemotherapy treated for VH repair. PMID- 27716307 TI - Lambda Red recombinase-mediated integration of the high molecular weight DNA into the Escherichia coli chromosome. AB - BACKGROUND: Escherichia coli K-12 is a frequently used host for a number of synthetic biology and biotechnology applications and chassis for the development of the minimal cell factories. Novel approaches for integrating high molecular weight DNA into the E. coli chromosome would therefore greatly facilitate engineering efforts in this bacterium. RESULTS: We developed a reliable and flexible lambda Red recombinase-based system, which utilizes overlapping DNA fragments for integration of the high molecular weight DNA into the E. coli chromosome. Our chromosomal integration strategy can be used to integrate high molecular weight DNA of variable length into any non-essential locus in the E. coli chromosome. Using this approach we integrated 15 kb DNA encoding sucrose catabolism and lactose metabolism and transport operons into the fliK locus of the flagellar region 3b in the E. coli K12 MG1655 chromosome. Furthermore, with this system we integrated 50 kb of Bacillus subtilis 168 DNA into two target sites in the E. coli K12 MG1655 chromosome. The chromosomal integrations into the fliK locus occurred with high efficiency, inhibited motility, and did not have a negative effect on the growth of E. coli. CONCLUSIONS: In addition to the rational design of synthetic biology devices, our high molecular weight DNA chromosomal integration system will facilitate metabolic and genome-scale engineering of E. coli.

AB - BACKGROUND: Compensation health research aims to study the influence of compensation systems, processes and practices on health and health-related outcomes. In many jurisdictions, injury compensation authorities collect substantial volumes of case and service level data for the purpose of administering the compensation system. An important secondary use of such data is research and analysis to explore interactions between individuals and organisations in compensation systems, and between compensation and other systems including healthcare and legal systems, in order to understand the role of compensation processes in injury recovery. RESULTS: The Compensation Research Database (CRD) established at the Institute for Safety Compensation and Recovery Research at Monash University, holds over 20 years of population-based data for transport and workplace injury in the state of Victoria, Australia. The CRD is unique in that it is held independently, at arm's length from the compensation authorities that collect the data, and its primary purpose is to support research and analyses to develop new insights into system and individual level outcomes. This paper describes the core elements of the database including the design, process and type of information collected. We review some of the research findings that have been published using the CRD, and describe the ongoing program of research utilising the database. CONCLUSIONS: The CRD is a unique administrative database that supports research into compensation health, with the objective of improving understanding of the interaction between injury compensation systems and injury recovery. The availability of the CRD for independent research is leading to substantial advancements in the compensation health research field and in related areas. PMID- 27716311 TI - Novel mammographic image features differentiate between interval and screen detected breast cancer: a case-case study. AB - BACKGROUND: Interval breast cancers are often diagnosed at a more advanced stage than screen-detected cancers. Our aim was to identify features in screening mammograms of the normal breast that would differentiate between future interval cancers and screen-detected cancers, and to understand how each feature affects tumor detectability. METHODS: From a population-based cohort of invasive breast cancer cases in Stockholm-Gotland, Sweden, diagnosed from 2001 to 2008, we analyzed the contralateral mammogram at the preceding negative screening of 394 interval cancer cases and 1009 screen-detected cancers. We examined 32 different image features in digitized film mammograms, based on three alternative dense area identification methods, by a set of logistic regression models adjusted for percent density with interval cancer versus screen-detected cancer as the outcome. Features were forward-selected into a multiple logistic regression model adjusted for mammographic percent density, age, BMI and use of hormone replacement therapy. The associations of the identified features were assessed also in a sample from an independent cohort. RESULTS: Two image features, 'skewness of the intensity gradient' and 'eccentricity', were associated with the risk of interval compared with screen-detected cancer. For the first feature, the per-standard deviation odds ratios were 1.32 (95 % CI: 1.12 to 1.56) and 1.21 (95 % CI: 1.04 to 1.41) in the primary and validation cohort respectively. For the second feature, they were 1.20 (95 % CI: 1.04 to 1.39) and 1.17 (95%CI: 0.98 to 1.39) respectively. The first feature was associated with the tumor size at screen detection, while the second feature was associated with the tumor size at interval detection. CONCLUSIONS: We identified two novel mammographic features in screening mammograms of the normal breast that differentiated between future interval cancers and screen-detected cancers. We present a starting point for further research into features beyond percent density that might be relevant for interval cancer, and suggest ways to use this information to improve screening. PMID- 27716309 TI - Correlation of an epigenetic mitotic clock with cancer risk. AB - BACKGROUND: Variation in cancer risk among somatic tissues has been attributed to variations in the underlying rate of stem cell division. For a given tissue type, variable cancer risk between individuals is thought to be influenced by extrinsic factors which modulate this rate of stem cell division. To date, no molecular mitotic clock has been developed to approximate the number of stem cell divisions in a tissue of an individual and which is correlated with cancer risk. RESULTS: Here, we integrate mathematical modeling with prior biological knowledge to construct a DNA methylation-based age-correlative model which approximates a mitotic clock in both normal and cancer tissue. By focusing on promoter CpG sites that localize to Polycomb group target genes that are unmethylated in 11 different fetal tissue types, we show that increases in DNA methylation at these sites defines a tick rate which correlates with the estimated rate of stem cell division in normal tissues. Using matched DNA methylation and RNA-seq data, we further show that it correlates with an expression-based mitotic index in cancer tissue. We demonstrate that this mitotic-like clock is universally accelerated in cancer, including pre-cancerous lesions, and that it is also accelerated in normal epithelial cells exposed to a major carcinogen. CONCLUSIONS: Unlike other epigenetic and mutational clocks or the telomere clock, the epigenetic clock proposed here provides a concrete example of a mitotic-like clock which is universally accelerated in cancer and precancerous lesions. PMID- 27716312 TI - Characterizing physical activity and food urban environments: a GIS-based multicomponent proposal. AB - BACKGROUND: Healthier urban environments influence the distribution of cardiovascular risk factors. Our aim was to design and implement a multicomponent method based on Geographic Information Systems to characterize and evaluate environmental correlates of obesity: the food and the physical activity urban environments. METHODS: Study location comprised a socio-demographically average urban area of 12 contiguous census sections (~16,000 residents), in Madrid, Spain. We conducted on-field audits on all food stores and street segments. We designed a synthetic index integrating continuous measures of both environments, by kernel density analyses. Index ranges from 0 to 100 (least-most healthy). RESULTS: We found a heterogeneous distribution with 75 and 50 % of the area scoring less than 36.8 and 25.5, respectively. Census sections of study area were categorized by Jenks intervals as high, medium-high, medium-low and low. 41.0 % of residents lived in an area with a low score, 23.6 % medium-low and 31.1 % medium-high and 4.2 % in a high. CONCLUSION: The proposed synthetic index may be a relevant tool to inform urban health interventions, providing a feasible way to integrate different measures of barriers and facilitators of healthy urban environments in terms of food and physical activity. PMID- 27716310 TI - Hyperchloremia and moderate increase in serum chloride are associated with acute kidney injury in severe sepsis and septic shock patients. AB - BACKGROUND: Acute kidney injury and hyperchloremia are commonly present in critically ill septic patients. Our study goal was to evaluate the association of hyperchloremia and acute kidney injury in severe sepsis and septic shock patients. METHODS: In this retrospective cohort study in a provincial tertiary care hospital, adult patients with severe sepsis or septic shock and serum chloride measurements were included. Serum chloride was measured on a daily basis for 48 hours. Primary outcome was development of acute kidney injury (AKI) and association of AKI and serum chloride parameters was analyzed. RESULTS: A total of 240 patients were included in the study, 98 patients (40.8 %) had hyperchloremia. The incidence of acute kidney injury (AKI) was significantly higher in the hyperchloremia group (85.7 % vs 47.9 %; p < 0.001). Maximal chloride concentration in the first 48 hours ([Cl-]max) was significantly associated with AKI. In multivariate analysis, [Cl-]max was independently associated with AKI [adjusted odds ratio (OR) for AKI = 1.28 (1.02-1.62); p = 0.037]. The increase in serum chloride (Delta[Cl-] = [Cl-]max - initial chloride concentration) demonstrated a dose-dependent relationship with severity of AKI. The mean Delta[Cl-] in patients without AKI was 2.1 mmol/L while in the patients with AKI stage 1, 2 and 3 the mean Delta[Cl-] was 5.1, 5.9 and 6.7 mmol/L, respectively. A moderate increase in serum chloride (Delta[Cl-] >= 5 mmol/L) was associated with AKI [OR = 5.70 (3.00-10.82); p < 0.001], even in patients without hyperchloremia [OR = 8.25 (3.44-19.78); p < 0.001]. CONCLUSIONS: Hyperchloremia is common in severe sepsis and septic shock and independently associated with AKI. A moderate increase in serum chloride (Delta[Cl-] >=5 mmol/L) is associated with AKI even in patients without hyperchloremia. PMID- 27716313 TI - Supportive supervision for volunteers to deliver reproductive health education: a cluster randomized trial. AB - BACKGROUND: Community Health Volunteers (CHVs) can be effective in improving pregnancy and newborn outcomes through community education. Inadequate supervision of CHVs, whether due to poor planning, irregular visits, or ineffective supervisory methods, is, however, recognized as a weakness in many programs. There has been little research on best practice supervisory or accompaniment models. METHODS: From March 2014 to February 2015 a proof of concept study was conducted to compare training alone versus training and supportive supervision by paid CHWs (n = 4) on the effectiveness of CHVs (n = 82) to deliver education about pregnancy, newborn care, family planning and hygiene. The pair-matched cluster randomized trial was conducted in eight villages (four intervention and four control) in Budondo sub-county in Jinja, Uganda. RESULTS: Increases in desired behaviors were seen in both the intervention and control arms over the study period. Both arms showed high retention rates of CHVs (95 %). At 1 year follow-up there was a significantly higher prevalence of installed and functioning tippy taps for hand washing (p < 0.002) in the intervention villages (47 %) than control villages (35 %). All outcome and process measures related to home-visits to homes with pregnant women and newborn babies favored the intervention villages. The CHVs in both groups implemented what they learnt and were role models in the community. CONCLUSIONS: A team of CHVs and CHWs can facilitate families accessing reproductive health care by addressing cultural norms and scientific misconceptions. Having a team of 2 CHWs to 40 CHVs enables close to community access to information, conversation and services. Supportive supervision involves creating a non-threatening, empowering environment in which both the CHV and the supervising CHW learn together and overcome obstacles that might otherwise demotivate the CHV. While the results seem promising for added value with supportive supervision for CHVs undertaking reproductive health activities, further research on a larger scale will be needed to substantiate the effect. PMID- 27716314 TI - Lipid nanoemulsions and liposomes improve photodynamic treatment efficacy and tolerance in CAL-33 tumor bearing nude mice. AB - BACKGROUND: Photodynamic therapy (PDT) as promising alternative to conventional cancer treatments works by irradiation of a photosensitizer (PS) with light, which creates reactive oxygen species and singlet oxygen (1O2), that damage the tumor. However, a routine use is hindered by the PS's poor water solubility and extended cutaneous photosensitivity of patients after treatment. In our study we sought to overcome these limitations by encapsulation of the PS m tetrahydroxyphenylchlorin (mTHPC) into a biocompatible nanoemulsion (Lipidots). RESULTS: In CAL-33 tumor bearing nude mice we compared the Lipidots to the existing liposomal mTHPC nanoformulation Foslip and the approved mTHPC formulation Foscan. We established biodistribution profiles via fluorescence measurements in vivo and high performance liquid chromatography (HPLC) analysis. All formulations accumulated in the tumors and we could determine the optimum treatment time point for each substance (8 h for mTHPC, 24 h for Foslip and 72 h for the Lipidots). We used two different light doses (10 and 20 J/cm2) and evaluated immediate PDT effects 48 h after treatment and long term effects 14 days later. We also analyzed tumors by histological analysis and performing reverse transcription real-time PCR with RNA extracts. Concerning tumor destruction Foslip was superior to Lipidots and Foscan while with regard to tolerance and side effects Lipidots were giving the best results. CONCLUSIONS: We could demonstrate in our study that nanoformulations are superior to the free PS mTHPC. The development of a potent nanoformulation is of major importance because the free PS is related to several issues such as poor bioavailability, solubility and increased photosensibility of patients. We could show in this study that Foslip is very potent in destroying the tumors itself. However, because the Lipidots' biocompatibility is outstanding and superior to the liposomes we plan to carry out further investigations and protocol optimization. Both nanoformulations show great potential to revolutionize PDT in the future. PMID- 27716316 TI - Ultrasonographic assessment of bone erosions in the different subtypes of systemic lupus erythematosus arthritis: comparison with computed tomography. AB - BACKGROUND: The aim was to determine the accuracy of high-resolution ultrasonography (US) for detecting erosion in the metacarpophalangeal (MCP) and wrist joints of patients with different subtypes of systemic lupus erythematosus (SLE) arthritis, using computed tomography (CT) as the gold-standard reference method. METHOD: The ulnar head, radiocarpal and second to fifth MCP joints in 26 patients with SLE - 9 classified as having rhupus syndrome, 10 as having Jaccoud's arthropathy (JA) and 7 as having non-deforming non-erosive (NDNE) arthritis - were subdivided into areas and bilaterally evaluated for the presence of bone erosion by CT and US. On CT, erosion volume was scored according to the outcome measures in rheumatology-rheumatoid arthritis magnetic resonance imaging (OMERACT-RAMRIS) score. On US, erosions were semi-quantitatively scored 0-3 according to scoring by ultrasound structural erosion (ScUSSe) systems. RESULTS: Erosions were detected by CT in 92/728 areas (12.6 %) and by US in 43/728 areas (5.9 %). Sensitivity, specificity and accuracy of US overall was 36 %, 98 % and 90 % compared with 57 %, 98 % and 93 % in the dorsal and lateral aspects of the second and fifth MCP, which were identified as areas with the best US reliability. Adding wrist joints would capture a larger number of erosions without affecting the accuracy. US detected 90.0 % of CT erosions with bone volume loss >20 % and 51.2 % of erosions with bone volume loss >10 %. Patients with rhupus had a greater number of larger erosions than those with JA or NDNE arthritis, with prevalent involvement of the MCP joints. Overall reliability of US in detecting bone erosions was moderate for rhupus syndrome (0.55) and JA (0.58), but poor for NDNE arthritis (0.10). CONCLUSION: US had moderate sensitivity and excellent specificity for detection and semi-quantitative assessment of bone erosions in SLE. PMID- 27716315 TI - Comparison of supraintercondylar and supracondylar femur fractures treated with condylar buttress plates. AB - BACKGROUND: Treatment of supraintercondylar (AO/OTA 33-C) and supracondylar (AO/OTA 33-A) femur fractures is generally challenging. Standard treatments include open reduction and internal fixation. However, optimal implants are now being well-defined. This study focus on the comparison between clinical and functional outcomes of fractures treated with condylar buttress plates (CBPs). METHODS: We treated 87 patients with supraintercondylar or supracondylar femur fracture from 2004 to 2008, including 30 supraintercondylar and 24 supracondylar fractures treated with CBPs. Both knee and function scores (per Knee Society) were given to clinical and functional outcomes, and concomitant knee function was assessed per Mize criteria. RESULTS: Union rate of supraintercondylar fractures was 90 % (27/30) and supracondylar fractures was 91.7 % (22/24) (P = 0.68). In supraintercondylar group, 16.7 % revealed postoperative varus deformity, whereas none in supracondylar group (P = 0.045). Knee Society knee score was 73.6 in supraintercondylar group and 85.5 in supracondylar group (P = 0.009); and function score was 62.5 in supraintercondylar group and 83.1 in supracondylar group (P = 0.023). A satisfactory result based on modified Mize criteria was achieved in 50 % of supraintercondylar fractures and in 79.1 % of supracondylar fractures (P = 0.09). CONCLUSIONS: Use of CBPs for supraintercondylar and supracondylar femur fractures treatment led to a high union rate. However, a high rate of varus deformity occurred in patients with supraintercondylar but not supracondylar fractures. Moreover, CBP treatment in patients with supracondylar fractures led to better functional outcomes than those with supraintercondylar fractures. PMID- 27716317 TI - Why hospital physicians attend work while ill? The spiralling effect of positive and negative factors. AB - BACKGROUND: Recurrent reports from national and international studies show a persistent high prevalence of sickness presence among hospital physicians. Despite the negative consequences reported, we do not know a lot about the reasons why physicians choose to work when ill, and whether there may be some positive correlates of this behaviour that in turn may lead to the design of appropriate interventions. The aim of this study is to explore the perception and experience with sickness presenteeism among hospital physicians, and to explore possible positive and negative foundations and consequences associated with sickness presence. METHODS: Semi-structured interviews of 21 Norwegian university hospital physicians. RESULTS: Positive and negative dimensions associated with 1) evaluation of illness, 2) organizational structure, 3) organizational culture, and 4) individual factors simultaneously contributed to presenteeism. CONCLUSIONS: The study underlines the inherent complexity of the causal chain of events affecting sickness presenteeism, something that also inhibits intervention. It appears that sufficient staffing, predictability in employment, adequate communication of formal policies and senior physicians adopting the position of a positive role model are particularly important. PMID- 27716318 TI - Reliability and validity of the Chinese mandarin version of PedsQLTM 3.0 transplant module. AB - BACKGROUND: Long-term health-related quality of life (HRQoL) of pediatric patients after hematopoietic stem cell transplantation (HSCT) is increasingly studied worldwide. However, few studies have been performed in China, where no uniform scale is available; the PedsQLTM Cancer Module 3.0 Chinese Mandarin version has been used to evaluate HRQoL of patients after HSCT in China. This study aimed to assess the reliability and validity of the Chinese Mandarin version of PedsQLTM 3.0 Transplant Module. METHODS: Patients between 2 and 18 years old, who underwent HSCT from January 2006 to June 2014, were recruited in Beijing Children's Hospital affiliated to Capital Medical University, the First Affiliated Hospital of Southern Medical University and Beijing Daopei Hospital. 207 parent reports and 182 child self-reports of the PedsQLTM 3.0 Transplant Module Chinese Mandarin version were assigned, of which 362 were returned. RESULTS: No missing item response was observed in the returned reports. Cronbach's alpha coefficient exceeded 0.7 in total scale and every dimension. The intraclass correlation coefficient exceeded 0.8 in all dimensions of child self reports and parent reports. Spearman's rank correlation coefficients of items and their respective dimensions were 0.6-0.94 in parent reports, and 0.62-0.93 in child self-reports, while a weak association was found between the items and other dimensions. Exploratory factor analysis indicated a good extraction effect, and construct validity of the scale was >60 %. CONCLUSIONS: The Chinese Mandarin version of PedsQLTM 3.0 Transplant Module has good feasibility, reliability and validity. Its use may help improve the HRQoL of children after HSCT in China. PMID- 27716319 TI - Local spatial variations analysis of smear-positive tuberculosis in Xinjiang using Geographically Weighted Regression model. AB - BACKGROUND: The spatial interplay between socioeconomic factors and tuberculosis (TB) cases contributes to the understanding of regional tuberculosis burdens. Historically, local Poisson Geographically Weighted Regression (GWR) has allowed for the identification of the geographic disparities of TB cases and their relevant socioeconomic determinants, thereby forecasting local regression coefficients for the relations between the incidence of TB and its socioeconomic determinants. Therefore, the aims of this study were to: (1) identify the socioeconomic determinants of geographic disparities of smear positive TB in Xinjiang, China (2) confirm if the incidence of smear positive TB and its associated socioeconomic determinants demonstrate spatial variability (3) compare the performance of two main models: one is Ordinary Least Square Regression (OLS), and the other local GWR model. METHODS: Reported smear-positive TB cases in Xinjiang were extracted from the TB surveillance system database during 2004 2010. The average number of smear-positive TB cases notified in Xinjiang was collected from 98 districts/counties. The population density (POPden), proportion of minorities (PROmin), number of infectious disease network reporting agencies (NUMagen), proportion of agricultural population (PROagr), and per capita annual gross domestic product (per capita GDP) were gathered from the Xinjiang Statistical Yearbook covering a period from 2004 to 2010. The OLS model and GWR model were then utilized to investigate socioeconomic determinants of smear positive TB cases. Geoda 1.6.7, and GWR 4.0 software were used for data analysis. RESULTS: Our findings indicate that the relations between the average number of smear-positive TB cases notified in Xinjiang and their socioeconomic determinants (POPden, PROmin, NUMagen, PROagr, and per capita GDP) were significantly spatially non-stationary. This means that in some areas more smear-positive TB cases could be related to higher socioeconomic determinant regression coefficients, but in some areas more smear-positive TB cases were found to do with lower socioeconomic determinant regression coefficients. We also found out that the GWR model could be better exploited to geographically differentiate the relationships between the average number of smear-positive TB cases and their socioeconomic determinants, which could interpret the dataset better (adjusted R 2 = 0.912, AICc = 1107.22) than the OLS model (adjusted R 2 = 0.768, AICc = 1196.74). CONCLUSIONS: POPden, PROmin, NUMagen, PROagr, and per capita GDP are socioeconomic determinants of smear-positive TB cases. Comprehending the spatial heterogeneity of POPden, PROmin, NUMagen, PROagr, per capita GDP, and smear positive TB cases could provide valuable information for TB precaution and control strategies. PMID- 27716320 TI - Bosentan and macitentan prevent the endothelial-to-mesenchymal transition (EndoMT) in systemic sclerosis: in vitro study. AB - BACKGROUND: Systemic sclerosis (SSc) is characterized by early vascular abnormalities and subsequent fibroblast activation to myofibroblasts, leading to fibrosis. Recently, endothelial-to-mesenchymal transition (EndoMT), a complex biological process in which endothelial cells lose their specific markers and acquire a mesenchymal or myofibroblastic phenotype, has been reported in SSc. In the present study, we evaluated the ability of endothelin-1 (ET-1) dual receptor antagonists bosentan (BOS) and macitentan (MAC) to antagonize EndoMT in vitro. METHODS: Ten women with limited SSc were enrolled. They underwent double skin biopsy (affected and nonaffected skin). Fibroblasts and microvascular endothelial cells (MVECs) were isolated from biopsies. We performed mono- or coculture of MVECs (isolated from nonaffected skin) with fibroblasts (isolated from affected skin and stimulated with ET-1 and transforming growth factor beta [TGF-beta]). In cocultures, the MVEC layer was left undisturbed or was preincubated with BOS or MAC. After 48 h of coculture, MVECs were analyzed for their tube formation ability and for messenger RNA and protein expression of different vascular (CD31, vascular endothelial growth factor-A [VEGF-A], VEGF-A165b) and profibrotic (alpha smooth muscle actin [alpha-SMA], collagen type I [Col I], TGF-beta) molecules. RESULTS: After 48 h, MVECs showed a reduced tube formation ability when cocultured with SSc fibroblasts. CD31 and VEGF-A resulted in downregulation, while VEGF-A165b, the antiangiogenic isoform, resulted in upregulation. At the same time, mesenchymal markers alpha-SMA, Col I, and TGF-beta resulted in overexpression in MVECs. Tube formation ability was restored when MVECs were preincubated with BOS or MAC, also reducing the expression of mesenchymal markers and restoring CD31 expression and the imbalance between VEGF-A and VEGF-A165b. CONCLUSIONS: With this innovative EndoMT in vitro model realized by coculturing nonaffected MVECs with affected SSc fibroblasts, we show that the presence of a myofibroblast phenotype in the fibroblast layer, coupled with an ET-1-TGF-beta synergic effect, is responsible for EndoMT. BOS and MAC seem able to antagonize this phenomenon in vitro, confirming previous evidence of endothelium-derived fibrosis in SSc and possible pharmacological interference. PMID- 27716321 TI - Blood pulsation measurement using cameras operating in visible light: limitations. AB - BACKGROUND: The paper presents an automatic method for analysis and processing of images from a camera operating in visible light. This analysis applies to images containing the human facial area (body) and enables to measure the blood pulse rate. Special attention was paid to the limitations of this measurement method taking into account the possibility of using consumer cameras in real conditions (different types of lighting, different camera resolution, camera movement). METHODS: The proposed new method of image analysis and processing was associated with three stages: (1) image pre-processing-allowing for the image filtration and stabilization (object location tracking); (2) main image processing-allowing for segmentation of human skin areas, acquisition of brightness changes; (3) signal analysis-filtration, FFT (Fast Fourier Transformation) analysis, pulse calculation. RESULTS AND CONCLUSIONS: The presented algorithm and method for measuring the pulse rate has the following advantages: (1) it allows for non contact and non-invasive measurement; (2) it can be carried out using almost any camera, including webcams; (3) it enables to track the object on the stage, which allows for the measurement of the heart rate when the patient is moving; (4) for a minimum of 40,000 pixels, it provides a measurement error of less than +/-2 beats per minute for p < 0.01 and sunlight, or a slightly larger error (+/-3 beats per minute) for artificial lighting; (5) analysis of a single image takes about 40 ms in Matlab Version 7.11.0.584 (R2010b) with Image Processing Toolbox Version 7.1 (R2010b). PMID- 27716322 TI - Spatial analysis and characteristics of pig farming in Thailand. AB - BACKGROUND: In Thailand, pig production intensified significantly during the last decade, with many economic, epidemiological and environmental implications. Strategies toward more sustainable future developments are currently investigated, and these could be informed by a detailed assessment of the main trends in the pig sector, and on how different production systems are geographically distributed. This study had two main objectives. First, we aimed to describe the main trends and geographic patterns of pig production systems in Thailand in terms of pig type (native, breeding, and fattening pigs), farm scales (smallholder and large-scale farming systems) and type of farming systems (farrow to-finish, nursery, and finishing systems) based on a very detailed 2010 census. Second, we aimed to study the statistical spatial association between these different types of pig farming distribution and a set of spatial variables describing access to feed and markets. RESULTS: Over the last decades, pig population gradually increased, with a continuously increasing number of pigs per holder, suggesting a continuing intensification of the sector. The different pig production systems showed very contrasted geographical distributions. The spatial distribution of large-scale pig farms corresponds with that of commercial pig breeds, and spatial analysis conducted using Random Forest distribution models indicated that these were concentrated in lowland urban or peri-urban areas, close to means of transportation, facilitating supply to major markets such as provincial capitals and the Bangkok Metropolitan region. Conversely the smallholders were distributed throughout the country, with higher densities located in highland, remote, and rural areas, where they supply local rural markets. A limitation of the study was that pig farming systems were defined from the number of animals per farm, resulting in their possible misclassification, but this should have a limited impact on the main patterns revealed by the analysis. CONCLUSIONS: The very contrasted distribution of different pig production systems present opportunities for future regionalization of pig production. More specifically, the detailed geographical analysis of the different production systems will be used to spatially-inform planning decisions for pig farming accounting for the specific health, environment and economical implications of the different pig production systems. PMID- 27716323 TI - Precise film dosimetry for stereotactic radiosurgery and stereotactic body radiotherapy quality assurance using GafchromicTM EBT3 films. AB - PURPOSE: The purpose of this study is to evaluate the dosimetric uncertainty associated with GafchromicTM (EBT3) films and establish a practical and efficient film dosimetry protocol for Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiotherapy (SBRT). METHOD AND MATERIALS: EBT3 films were irradiated at each of seven different dose levels between 1 and 15 Gy with open fields and standard deviations of dose maps were calculated at each color channel for evaluation. A scanner non-uniform response correction map was built by registering and comparing film doses to the reference ion chamber array-based dose map delivered with the same doses. To determine the temporal dependence of EBT3 films, the average correction factors of different dose levels as a function of time were evaluated up to 4 days after irradiation. An integrated film dosimetry protocol was developed for dose calibration, calibration curve fitting, dose mapping, and profile/gamma analysis. Patient specific quality assurance (PSQA) was performed for 83 SRS/SBRT treatment plans, and analysis of the measurements and calculations are presented here. RESULTS: The scanner response varied within 1 % for the field sizes less than 5 * 5 cm2, and up to 5 % for the field sizes of 10 * 10 cm2 for all color channels. The scanner correction method was able to remove visually evident, irregular detector responses for larger field sizes. The dose response of the film changed rapidly (~10 %) in the first two hours and became smooth plateaued afterwards, ~3 % change between 2 and 24 h. The uncertainties were approximately 1.5, 1.7 and 4.8 % over the dose range of 3~15 Gy for the red, green and blue channels. The green channel showed very high sensitivity and low uncertainty in the dose range between 10 and 15 Gy, which is suitable for SRS/SBRT commissioning and PSQA. The difference between the calculated dose and measured dose of ion chamber measurement at isocenter was -0.64 +/- 2.02 for all plans, corresponding to a 95 % confidence interval of (-1.09, -0.26). The percentage of points passing the 3 %/1 mm gamma criteria in absolute dose, averaged over all tests was 95.0 +/- 4.2. CONCLUSION: We have developed the EBT3 films based dosimetry protocol to obtain absolute dose values. The overall uncertainty has been established to be 1.5 % for SRS and SBRT PSQA. PMID- 27716324 TI - Sarilumab plus methotrexate suppresses circulating biomarkers of bone resorption and synovial damage in patients with rheumatoid arthritis and inadequate response to methotrexate: a biomarker study of MOBILITY. AB - BACKGROUND: Interleukin 6 (IL-6) signaling plays a key role in the pathophysiology of rheumatoid arthritis (RA) and is inhibited by sarilumab, a human monoclonal antibody blocking the IL-6 receptor alpha (IL-6Ralpha). The effects of sarilumab plus methotrexate (MTX) on serum biomarkers of joint damage and bone resorption were assessed in two independent studies (phase II (part A) and phase III (part B)) of patients with RA with a history of inadequate response to MTX from the MOBILITY study (NCT01061736). METHODS: Serum samples were analyzed at baseline and prespecified posttreatment time points. Biomarkers of tissue destruction, cartilage degradation, and synovial inflammation were measured in part A; assessment of these markers was repeated in part B and included additional analysis of biomarkers of bone formation and resorption (including soluble receptor activator of nuclear factor-kB ligand (sRANKL)). A mixed model for repeated measures was used to compare treatment effects on change in biomarkers. Additionally, changes from baseline in biomarkers were compared between American College of Rheumatology 50 % responders and nonresponders and between patients who achieved or did not achieve low disease activity (LDA), separately by treatment group, at week 24. RESULTS: In part A, sarilumab 150 and 200 mg every 2 weeks (q2w) significantly reduced biomarkers of tissue destruction, cartilage degradation, and synovial inflammation at both 2 and 12 weeks posttreatment (p < 0.05 vs placebo). These results were replicated in part B, with markers of these damaging processes reduced at weeks 2 and 24 (p < 0.05 vs placebo). Additionally, sarilumab 200 mg q2w significantly reduced both sRANKL and sRANKL/osteoprotegerin ratio at week 24 (p < 0.01 vs placebo). Trends for reduction were noted for several biomarkers in patients who achieved LDA compared with those who did not. CONCLUSIONS: Sarilumab plus MTX significantly suppressed biomarkers of bone resorption and joint damage, as compared with placebo plus MTX, in patients with RA. Additional work is needed to determine whether differences in biomarker profiles at baseline or posttreatment can identify patients who achieve improvement in disease activity. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01061736 , February 2, 2010. PMID- 27716325 TI - A scoping review of Australian allied health research in ehealth. AB - BACKGROUND: Uptake of e-health, the use of information communication technologies (ICT) for health service delivery, in allied health appears to be lagging behind other health care areas, despite offering the potential to address problems with service access by rural and remote Australians. The aim of the study was to conduct a scoping review of studies into the application of or attitudes towards ehealth amongst allied health professionals conducted in Australia. METHODS: Studies meeting inclusion criteria published from January 2004 to June 2015 were reviewed. Professions included were audiology, dietetics, exercise physiology, occupational therapy, physiotherapy, podiatry, social work, and speech pathology. Terms for these professions and forms of ehealth were combined in databases of CINAHL (EBSCO), Cochrane Library, PsycINFO (1806 - Ovid), MEDLINE (Ovid) and AMED (Ovid). RESULTS: Forty-four studies meeting inclusion criteria were summarised. They were either trials of aspects of ehealth service delivery, or clinician and/or client use of and attitudes towards ehealth. Trials of ehealth were largely from two research groups located at the Universities of Sydney and Queensland; most involved speech pathology and physiotherapy. Assessments through ehealth and intervention outcomes through ehealth were comparable with face-to face delivery. Clinicians used ICT mostly for managing their work and for professional development, but were reticent about its use in service delivery, which contrasted with the more positive attitudes and experiences of clients. CONCLUSION: The potential of ehealth to address allied health needs of Australians living in rural and remote Australia appears unrealised. Clinicians may need to embrace ehealth as a means to radicalise practice, rather than replicate existing practices through a different mode of delivery. PMID- 27716326 TI - Physical activity throughout adolescence and body composition at 18 years: 1993 Pelotas (Brazil) birth cohort study. AB - BACKGROUND: Adolescence is a period of accelerated development and increases in body composition. Physical activity (PA) practice has been associated with the development of major components of body composition (bone, muscle and fat). However, the longitudinal effects of PA of different intensities during adolescence are still not well understood. Thus, the main goal this study has investigate the association between practice of moderate- and vigorous-intensity physical activity throughout adolescence and body composition, specifically lean mass (LM) and fat mass (FM), at age 18. METHODS: In this cohort study, physical activity was measured at 11, 15 and 18 years, using questionnaires. Thresholds of 300, 150 and 75 min per week, were used for MVPA, moderate- and vigorous intensity physical activity, respectively. Consistent physical activity was defined as reaching the thresholds at the three follow-ups. FM and LM at age 18 were assessed by DXA and expressed as fat mass (FMI) and lean mass (LMI) indexes. To verify the association between the trajectories of MVPA, moderate- and vigorous-intensity physical activity in adolescence and FM and LM at 18, multivariate analyses were performed through multiple linear regressions adjusted for co-variables. RESULTS: A total of 3,176 adolescents were evaluated. The consistent practice of moderate- and vigorous-intensity physical activity according to thresholds during adolescence were directly related to the LMI in boys (moderate-intensity - beta = 0.40 and CI95 % 0.13; 0.68 and vigorous intensity - beta = 0.95 and CI95 % 0.69; 1.21) and girls (Moderate-intensity - beta = 0.23 and CI95 % 0.02; 0.45 and vigorous-intensity - beta = 0.80 and CI95 % 0.29; 1.32). Practice of vigorous-intensity physical activity alone showed to be inversely associated with the FMI in boys (beta = -0.53 and CI95 % -0.96;-0.10). CONCLUSION: Consistent physical activity practice during adolescence was associated with greater lean mass in both sexes. In boys, vigorous-intensity physical activity was associated with less fat mass. PMID- 27716328 TI - Cardiorespiratory fitness: a comparison between children with renal transplantation and children with congenital solitary functioning kidney. AB - Children with end-stage renal disease are known to have a cardiorespiratory fitness significantly reduced. This is considered to be an independent index predictive of mortality mainly due to cardiovascular accidents. The effects of renal transplantation on cardiorespiratory fitness are incompletely known. We compared the maximal oxygen uptake (VO2 max) of children with a functioning renal transplant with that of children with congenital solitary functioning kidney, taking into consideration also the amount of weekly sport activity. PMID- 27716327 TI - Living together in biofilms: the microbial cell factory and its biotechnological implications. AB - In nature, bacteria alternate between two modes of growth: a unicellular life phase, in which the cells are free-swimming (planktonic), and a multicellular life phase, in which the cells are sessile and live in a biofilm, that can be defined as surface-associated microbial heterogeneous structures comprising different populations of microorganisms surrounded by a self-produced matrix that allows their attachment to inert or organic surfaces. While a unicellular life phase allows for bacterial dispersion and the colonization of new environments, biofilms allow sessile cells to live in a coordinated, more permanent manner that favors their proliferation. In this alternating cycle, bacteria accomplish two physiological transitions via differential gene expression: (i) from planktonic cells to sessile cells within a biofilm, and (ii) from sessile to detached, newly planktonic cells. Many of the innate characteristics of biofilm bacteria are of biotechnological interest, such as the synthesis of valuable compounds (e.g., surfactants, ethanol) and the enhancement/processing of certain foods (e.g., table olives). Understanding the ecology of biofilm formation will allow the design of systems that will facilitate making products of interest and improve their yields. PMID- 27716329 TI - Long noncoding RNA expression profile in fibroblast-like synoviocytes from patients with rheumatoid arthritis. AB - BACKGROUND: Long noncoding RNAs (lncRNAs) have recently received wide attention as key molecules that mediate a variety of physiological and pathological processes by regulating gene expression; however, knowledge of lncRNAs in rheumatoid arthritis (RA) is limited. Thus, we investigated the lncRNA expression profile in fibroblast-like synoviocytes (FLSs) from patients with RA and explored the function of abundantly expressed lncRNAs. METHODS: LncRNA and mRNA microarrays were performed to identify differentially expressed lncRNAs in RA FLSs compared with normal FLSs. Quantitative polymerase chain reaction (qPCR) was used to validate the results, and correlation analysis was used to analyze the relationship between these aberrantly expressed lncRNAs and clinical characteristics. A receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic value of the lncRNAs identified. RESULTS: According to the gene expression profiles, 135 lncRNAs were differentially expressed between RA and normal FLSs. Furthermore, qPCR data showed that lncRNA ENST00000483588 was up-regulated and that three lncRNAs (ENST00000438399, uc004afb.1, and ENST00000452247) were down-regulated in RA FLSs. The expression level of ENST00000483588 was positively correlated with the level of C-reactive protein and the Simplified Disease Activity Index score. Moreover, the areas under the ROC curve were 0.85, 0.92, 0.97, and 0.92 for ENST00000483588, ENST00000438399, uc004afb.1, and ENST00000452247, respectively. CONCLUSIONS: The results indicate that the dysregulation of ENST00000483588, ENST00000438399, uc004afb.1, and ENST00000452247 may be involved in the pathological processes of RA and that these lncRNAs may have potential value for the diagnosis and assessment of the disease activity of RA. PMID- 27716331 TI - Bedside PDA ligation in premature infants less than 28 weeks and 1000 grams. AB - BACKGROUND: PDA(Patent ductus arteriosus) is a common and clinically important condition which is presented with a number of hemodynamic and respiratory problems such as intraventricular hemorrhage, pulmonary hemorrhage and necrotizing enterocolitis due to increased pulmonary blood flow and stealing from systemic circulation. The incidence of PDA among the infants that were born before the 28th gestational week is as high as 70 %; and spontaneous closure rates in very-low-birth-weight premature neonates(VLBWPN) is around 34 %. The onset, duration, and repeat number of consecutive courses of the prostaglandin synthesis inhibitor medication for PDA closure are still issues of debate. Bed side PDA closure is a safe surgical procedure in both mature and premature babies. Here we aim to retrospectively present our 26 cases which were less than 28 weeks and 1000 grams that underwent bed-side PDA ligation. METHODS: This retrospective study included 26 VLBWPN with PDA that underwent bed-side ligation between 2012 and 2015. Babies were born before the 28th gestational week (23-27 weeks) and less than 1000 grams (489-970 gr). Of the 26, 15 were female and 11 were male. Indomethacin was administered to all of the cases as the medical closing agent. The medication was stopped due to unwanted effects in 6 cases. All of the patients took medical treatment before surgery. RESULTS: No surgical mortality occurred during our study. One case of pneumothorax was recorded as late surgical complication. Five of the 26 patients were lost, and the most common cause of mortality was sepsis (in 3 cases). The remaining 21 cases were discharged on days 86-238. The follow-up periods of the patients were 2 moths - 3 years. The most frequent problems encountered after discharge was chronic lung problems. CONCLUSIONS: Bed side PDA ligation surgery in the ICU is a safe method for VLBWPN with clinically significant PDA. PMID- 27716330 TI - Survival rate and perioperative data of patients who have undergone hemipelvectomy: a retrospective case series. AB - BACKGROUND: Hemipelvectomy is a major orthopedic surgical procedure indicated in specific situations. Although many studies discuss surgical techniques for hemipelvectomy, few studies have presented survival data, especially in underdeveloped countries. Additionally, there is limited information on anesthesia for orthopedic oncologic surgeries. The primary aim of this study was to determine the survival rate after hemipelvectomy, and the secondary aims were to evaluate anesthesia and perioperative care associated with hemipelvectomy and determine the influence of the surgical technique (external hemipelvectomy [amputation] or internal hemipelvectomy [limb sparing surgery]) on anesthesia and perioperative care in Brazil. METHODS: This retrospective case series collected data from 35 adult patients who underwent hemipelvectomy between 2000 and 2013. Survival rates after surgery were determined, and group comparisons were performed using the Kaplan-Meier method and the log-rank test. Mantel-Cox test and multiple linear regression analysis with stepwise forward selection were performed for univariate and multivariate analyses, respectively. RESULTS: Mean survival time was 32.8 +/- 4.6 months and 5-year survival rate was 27 %. Of the 35 patients, 23 patients (65.7 %) underwent external hemipelvectomy and 12 patients (34.3 %) underwent internal hemipelvectomy. The survival rate was significantly higher in patients with bone tumors than in those with soft tissue sarcomas (P = 0.024). The 5-year cumulative probability of survival was significantly lower in patients who underwent external hemipelvectomy than in those who underwent internal hemipelvectomy (P = 0.043). In the univariate and multivariate analyses, only advanced disease stage (3 and 4) was identified as a significant independent predictor of reduced survival (P = 0.0003). Balanced general anesthesia combined with epidural block was the most frequent anesthesia technique. Median intraoperative crystalloid volume and red blood cell transfusions were 3500 mL and 2 units, respectively. CONCLUSIONS: Overall mean survival time after hemipelvectomy was 32.8 months. Advanced disease stage might be independently associated with reduced survival. Smaller amounts of fluids and transfusions were administered and time to discharge was shorter. Acute and chronic pain as well as wound complications are still important challenges in hemipelvectomy. PMID- 27716332 TI - Anti-citrullinated protein antibodies and high levels of rheumatoid factor are associated with systemic bone loss in patients with early untreated rheumatoid arthritis. AB - BACKGROUND: Autoantibodies such as anti-citrullinated protein antibodies (ACPA) are major risk factors for articular bone destruction from the earliest phases of rheumatoid arthritis (RA). The aim of the current study was to determine whether RA-associated autoantibodies also impact on systemic bone loss in patients with early disease. METHODS: Systemic bone mineral density (BMD) was measured in the lumbar spine and the hip in 155 consecutive treatment-naive patients with early RA (median symptom duration 13 weeks). Demographic and disease-specific parameters, including clinical disease activity, ultrasonographic (US) examination of the hands and wrists, radiographic scoring of joint damage, ACPA and rheumatoid factor (RF) levels were recorded from all patients. Reduced BMD was defined as Z score <= -1 SD and analysed in relation to disease-related characteristics and autoantibody subgroups. RESULTS: Reduced BMD was found in 25.5 % of the patients in the spine and 19.4 % in the hip. Symptom duration, clinical and US disease activity, functional disability and radiographic damage did not significantly impact on spine and hip BMD loss in regression analyses adjusted for possible confounders (age, gender, menopausal status, current smoking, body mass index). In contrast, ACPA positivity (at any level) negatively affected the spine Z-score (adjusted OR (95 % CI) 2.76 (1.19 to 6.42)); the hip Z score was affected by high titres only (adjusted OR (95 % CI) 2.96 (1.15 to 7.66)). The association of ACPA with reduced BMD in the spine was confirmed even at low levels of RF (adjusted OR (95 % CI) 2.65 (1.01 to 7.24)), but was further increased by concomitant high RF (adjusted OR (95 % CI) 3.38 (1.11 to 10.34)). In contrast, Z scores in the hip were significantly reduced only in association with high ACPA and RF (adjusted OR (95 % CI) 4.96 (1.48 to 16.64)). CONCLUSIONS: Systemic BMD in patients with early RA is reduced in relation with ACPA positivity and high RF levels. This finding supports the notion that RA associated autoimmunity may have a direct causative role in bone remodeling. PMID- 27716333 TI - Catabolic and proinflammatory effects of leptin in chondrocytes are regulated by suppressor of cytokine signaling-3. AB - BACKGROUND: Previous studies provide evidence that adipokine leptin increases production of catabolic and proinflammatory factors in chondrocytes and serves as a link between obesity and osteoarthritis (OA). However, the magnitude of the response to leptin treatment varies greatly between chondrocytes from different donor patients. In the present study, we investigated the regulatory role of suppressor of cytokine signaling-3 (SOCS-3) in the leptin-induced responses in OA cartilage. METHODS: Cartilage and synovial fluid samples from 97 patients with OA undergoing knee replacement surgery were collected. Cartilage samples were cultured with leptin (10 MUg/ml), and the levels of proinflammatory and catabolic factors in synovial fluid and in the cartilage culture media, and SOCS-3 expression in the cartilage were measured. The role of SOCS-3 in leptin signaling was further studied in H4 murine chondrocytes by downregulating SOCS-3 with siRNA. RESULTS: Leptin-induced expression of matrix metalloproteinases MMP-1, MMP 3, MMP-13, interleukin-6 (IL-6), inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were higher in the cartilage samples with low SOCS-3 expression. Accordingly, downregulation of SOCS-3 by siRNA in H4 chondrocytes led to enhanced leptin-induced expression of MMP-3, MMP-13, IL-6 and iNOS. Synovial fluid leptin was associated positively, and cartilage SOCS-3 negatively with synovial fluid levels of MMPs in a multivariate model in obese (body mass index (BMI) >30 kg/m2) but not in non-obese (BMI <30 kg/m2) patients. CONCLUSIONS: Our results show, for the first time, that SOCS-3 regulates leptin-induced responses in cartilage, and could thus be a future drug target in the treatment or prevention of OA, especially in obese patients. PMID- 27716335 TI - Feasibility of community level interventions for pre-eclampsia: perspectives, knowledge and task-sharing from Nigeria, Mozambique, Pakistan and India. AB - Hypertensive disorders of pregnancy (HDP), particularly pre-eclampsia and eclampsia, remain one of the leading causes of maternal mortality and are contributory in many foetal/newborn deaths. This editorial discusses a supplement of seven papers which provide the results of the first round of the CLIP (Community Level Interventions for Pre-eclampsia) Feasibility Studies. These studies report a number of enablers and barriers in each setting, which have informed the implementation of a cluster-randomized trial (cRCT) aimed at reducing pre-eclampsia-related, and all-cause, maternal and perinatal mortality and major morbidity using community-based identification and treatment of pre eclampsia in selected geographies of Nigeria, Mozambique, Pakistan and India. This supplement unpacks the diverse community perspectives on determinants of maternal health, variant health worker knowledge and routine management of HDP, and viability of task sharing for preeclampsia identification and management in select settings. These studies demonstrate the need for strategies to improve health worker knowledge and routine management of HDP and consideration of expanding the role of community health workers to reach the most remote women and families with health education and access to health services. PMID- 27716336 TI - Adaptive vs. non-adaptive cognitive training by means of a personalized App: a randomized trial in people with multiple sclerosis. AB - BACKGROUND: Cognitive impairment is common in multiple sclerosis (MS), but the definition of the best cognitive rehabilitation tools and features is still an open issue among researchers. The aims of the present study were to evaluate the effectiveness of COGNI-TRAcK (a customized application software delivering personalized working memory-based exercises) on cognitively impaired people with MS and to investigate the effects of an adaptive vs. a non-adaptive cognitive training administered by means of COGNI-TRAcK. METHODS: Twenty eight patients (20 women, age 47.5 +/- 9.3 years, Expanded Disability Status Scale score 3.8 +/- 1.9) were randomized in two homogeneous groups, both performing a 8-week home based cognitive rehabilitation treatment by means of COGNI-TRAcK. The study group (ADAPT-gr) underwent an adaptive training given by the automatic adjustment of tasks difficulty to the subjects' performance, whilst the control group (CONST gr) was trained at constant difficulty levels. Before and after the treatment, patients' cognitive status was assessed using a gold standard neuropsychological evaluation. Moreover, the mostly affected cognitive domains in MS (i.e., attention, concentration and information processing speed) were also assessed 6 months after the end of the treatment. RESULTS: The analysis of variance showed a significant Group*Time interaction in six out of ten tests of the cognitive evaluation. Post-hoc analysis revealed a significant improvement between the performances before and after the intervention only in the ADAPT-gr in tests evaluating verbal memory acquisition (p <0.05) and delayed recall (p = 0.001), verbal fluency (p = 0.01), sustained attention, concentration and information processing speed (p < 0.01). This last effect was maintained also after 6 months (p < 0.05). CONCLUSIONS: We concluded that COGNI-TRAcK represents a suitable tool to administer a personalized training to cognitively impaired subjects and that an adaptive working load is a crucial feature determining the effectiveness of cognitive treatment, allowing transfer effects to several cognitive domains and long-term maintenance of results. PMID- 27716337 TI - Clinical and paraclinical profile, and predictors of outcome in 90 cases of scrub typhus, Meghalaya, India. AB - BACKGROUND: India is an integral component of "tsutsugamushi triangle" which depicts a part of the globe endemic to scrub typhus. Owing to frequent outbreaks witnessed in different parts of the country in the recent past, scrub typhus is described as a re-emerging infectious disease in India. The present study aimed to study the clinical and paraclinical profile, complications and predictors of outcome among 90 cases of scrub typhus diagnosed in a hospital of north-eastern India from Sept 2011 to Aug 2012. METHODS: A longitudinal study was conducted in a hospital of Meghalaya, India between Sept 2011 and Aug 2012. Diagnosis of scrub typhus was arrived by SD BIOLINE tsutsugamushi (solid phase immunochromatographic assay) rapid diagnostic test for antibodies (IgM, IgG or IgA). Descriptive analyses of age, gender, geographic area, symptoms and signs, treatment, laboratory findings, complications, and outcome were conducted. Relative risk (RR) with 95 % confidence interval (CI) was computed for Multiple Organ Dysfunction Syndrome (MODS) and mortality. Binary logistic regression was applied to the significant correlates (P < 0.05) on univariate analysis to identify the predictors of MODS and mortality in scrub typhus. RESULTS: As many as 662 clinically suspected scrub typhus patients were tested and 90 (13.6 %) were diagnosed to have scrub typhus. Out of 90 patients, 52.2 % (n = 47) were males and their mean (SD) age was 36.29 (13.38) years. Fever of <7 days (n = 75, 83.3 %), myalgia (n = 56, 62.2 %), pain abdomen (n = 24, 26.7 %), headache (n = 24, 26.7 %), nausea/vomiting (n = 21, 23.3 %), dry cough (n = 21, 23.3 %), hepatomegaly (n = 24, 26.7 %), splenomegaly (n = 22, 24.4 %), and lymphadenopathy (n = 20, 22.2 %) were the predominant clinical features. Eschar was seen in 10 patients (11.1 %). One third (n = 30) of the patients developed at least one systemic complication. Acute hepatitis (n = 15, 16.7 %), pneumonitis (n = 14, 15.6 %), and acute kidney injury (n = 11, 12.2 %) were the common complications. MODS was seen in 14.4 % (n = 13) and 38.5 % (n = 5) of the patients with MODS died. Overall, case fatality rate was 5.15 % (n = 5). On univariate analysis, platelets <100 000/mm3, serum creatinine >1.5 mg/dl, and transaminase (AST, ALT or both) >500 U/L were associated with MODS (P < 0.001) and mortality (P < 0.05). In addition, serum bilirubin >3 mg/dl was also associated with MODS (P < 0.001). On applying binary logistic regression, serum creatinine >1.5 mg/dl was a predictor of MODS (OR: 76.1, 95 % CI: 4.9-1175.6) and mortality (OR: 18.03, 95 % CI: 1.38-235.1). CONCLUSION: In this study setting, approximately one-seventh (13.6 %) of the acute undifferentiated febrile illness were due to scrub typhus. Systemic complications were common (33.3 %). Serum creatinine >1.5 mg/dl was a predictor of MODS and mortality. PMID- 27716334 TI - Multiple organ dysfunction and systemic inflammation after spinal cord injury: a complex relationship. AB - Spinal cord injury (SCI) is a devastating event that results in significant physical disabilities for affected individuals. Apart from local injury within the spinal cord, SCI patients develop a variety of complications characterized by multiple organ dysfunction or failure. These disorders, such as neurogenic pain, depression, lung injury, cardiovascular disease, liver damage, kidney dysfunction, urinary tract infection, and increased susceptibility to pathogen infection, are common in injured patients, hinder functional recovery, and can even be life threatening. Multiple lines of evidence point to pathological connections emanating from the injured spinal cord, post-injury systemic inflammation, and immune suppression as important multifactorial mechanisms underlying post-SCI complications. SCI triggers systemic inflammatory responses marked by increased circulation of immune cells and pro-inflammatory mediators, which result in the infiltration of inflammatory cells into secondary organs and persistence of an inflammatory microenvironment that contributes to organ dysfunction. SCI also induces immune deficiency through immune organ dysfunction, resulting in impaired responsiveness to pathogen infection. In this review, we summarize current evidence demonstrating the relevance of inflammatory conditions and immune suppression in several complications frequently seen following SCI. In addition, we highlight the potential pathways by which inflammatory and immune cues contribute to multiple organ failure and dysfunction and discuss current anti-inflammatory approaches used to alleviate post-SCI complications. A comprehensive review of this literature may provide new insights into therapeutic strategies against complications after SCI by targeting systemic inflammation. PMID- 27716338 TI - Rational design of cancer gene panels with OncoPaD. AB - BACKGROUND: Profiling the somatic mutations of genes which may inform about tumor evolution, prognostics and treatment is becoming a standard tool in clinical oncology. Commercially available cancer gene panels rely on manually gathered cancer-related genes, in a "one-size-fits-many" solution. The design of new panels requires laborious search of literature and cancer genomics resources, with their performance on cohorts of patients difficult to estimate. RESULTS: We present OncoPaD, to our knowledge the first tool aimed at the rational design of cancer gene panels. OncoPaD estimates the cost-effectiveness of the designed panel on a cohort of tumors and provides reports on the importance of individual mutations for tumorigenesis or therapy. With a friendly interface and intuitive input, OncoPaD suggests researchers relevant sets of genes to be included in the panel, because prior knowledge or analyses indicate that their mutations either drive tumorigenesis or function as biomarkers of drug response. OncoPaD also provides reports on the importance of individual mutations for tumorigenesis or therapy that support the interpretation of the results obtained with the designed panel. We demonstrate in silico that OncoPaD designed panels are more cost effective-i.e. detect a maximum fraction of tumors in the cohort by sequencing a minimum quantity of DNA-than available panels. CONCLUSIONS: With its unique features, OncoPaD will help clinicians and researchers design tailored next generating sequencing (NGS) panels to detect circulating tumor DNA or biopsy specimens, thereby facilitating early and accurate detection of tumors, genomics informed therapeutic decisions, patient follow-up and timely identification of resistance mechanisms to targeted agents. OncoPaD may be accessed through http://www.intogen.org/oncopad. PMID- 27716340 TI - Pharmacokinetics of calycopterin and xanthmicrol, two polymethoxylated hydroxyflavones with anti-angiogenic activities from Dracocephalum kotschyi Bioss. AB - BACKGROUND: Recently flavonoids have attracted the attention of researchers in the fight against cancer. Calycopterin and xanthomicrol, are two polymethoxylated flavonoids found in the aerial parts of Dracocephalum kotschyi Bioss.. We have recently shown that these compounds possess antiangiogenic activity and may be of value as potential anticancer agents. In order to demonstrate putative in vivo antitumor effect of these compounds we needed preliminary information on both pharmacokinetics and toxicological properties of these two agents. METHOD: A new online SPE HPLC method for measurement of calycopterin and xanthomicrol in rat plasma was developed. Pharmacokinetic parameters of calycopterin and xanthomicrol, after i.v. administration in rats, were determined. RESULTS: The plasma half-life for both agents was around 4 h, however, the volume of distribution of calycopterin appeared to be about 8 times greater than xanthomicrol. This was probably due the greater hydrophobicity of the former which had other consequences such as much smaller maximum plasma concentration of calycopterin compared to its less methoxylated congener. Preliminary toxicological study of xanthomicrol failed to show any behavioral, histological and biochemical adverse effects after repeated administrations of high doses. Pharmacokinetics of xanthomicrol in rats. PMID- 27716339 TI - Improving Ghana's mental healthcare through task-shifting- psychiatrists and health policy directors perceptions about government's commitment and the role of community mental health workers. AB - BACKGROUND: The scarcity of mental health professionals places specialist psychiatric care out of the reach of most people in low and middle income countries. There is growing interest in the effectiveness of task shifting as a strategy for targeting expanding health care demands in settings with shortages of qualified health personnel. Given this background, the aim of our study was to examine the perceptions of psychiatrists and health policy directors about the policy to expand mental health care delivery in Ghana through a system of task shifting from psychiatrists to community mental health workers (CMHWs). METHODS: A self-administered semi-structured questionnaire was developed and administered to 11 psychiatrists and 29 health policy directors. Key informant interviews were also held with five psychiatrists and four health policy directors. Quantitative data were analysed using descriptive statistics. Qualitative data were analysed thematically. RESULTS: Almost all the psychiatrists and 23 (79.3 %) health policy directors were aware of the policy of the Government of Ghana to improve on the human resource base within mental health through a system of task-shifting. Overall, about half of the psychiatrists and 9 (31 %) health policy directors perceived there is some professional resistance to the implementation of the policy of task shifting. The majority of respondents were of the view that CMHWs should be allowed to assess, diagnose and treat most of the common mental disorders. The respondents identified that CMHWs usually perform two sets of roles, namely; officially assigned roles for which they have the requisite training and assumed roles for which they usually do not have the requisite training. The stakeholders identified multiple challenges associated with current task shifting arrangements within Ghana's mental health delivery system, including inadequate training and supervision, poor awareness of the scope of their expertise on the part of the CMHWs. CONCLUSION: Psychiatrists and health policy directors support the policy to expand mental health service coverage in Ghana through a system of task-shifting, despite their awareness of resistance from some professionals. It is important that the Government of Ghana upholds its commitment of expanding mental healthcare by maintaining and prioritizing its policy on task shifting and also providing the necessary resources to ensure its success. PMID- 27716341 TI - Celastrus orbiculatus extract inhibits the migration and invasion of human glioblastoma cells in vitro. AB - BACKGROUND: Gliomas are highly aggressive tumors of the nervous system, and current treatments fail to improve patient survival. To identify substances that can be used as treatments for gliomas, we examined the effect of Celastrus orbiculatus extract (COE) on the invasion and migration of human glioblastoma U87 and U251 cells in vitro. METHODS: The effects of COE on cell viability and adhesion were tested using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H tetrazolium bromide assay and cell adhesion assay, respectively. The effects of COE on cell migration and invasion were assessed by a wound-healing assay and transwell migration and invasion assays. The effects of COE on the expression of epithelial-mesenchymal transition (EMT)-related proteins and matrix metalloproteinases (MMPs) were evaluated using western blot and gelatin zymography, respectively. Finally, the effect of COE on actin assembly was observed using phalloidin-tetramethylrhodamine isothiocyanate labeling and confocal laser scanning microscopy. RESULTS: We found that COE inhibited the adhesion, migration, and invasion of U87 and U251 cells in a dose-dependent manner. COE reduced N-cadherin and vimentin expression, increased E-cadherin expression, and reduced MMP-2 and MMP-9 expression in U87 and U251 cells. Furthermore, COE inhibited actin assembly in U87 and U251 cells. CONCLUSIONS: COE attenuates EMT, MMP expression, and actin assembly in human glioblastoma cells, thereby inhibiting their adhesion, migration, and invasion in vitro. PMID- 27716342 TI - Assessment of malaria control consultation and service posts in Yunnan, P. R. China. AB - BACKGROUND: This paper seeks to assess the function of malaria control consultation and service posts (MCCSPs) that are located on the border areas of Yunnan province, P.R. China, as a strategy for eliminating malaria among the mobile and migrant population in these areas. METHODS: A retrospective descriptive analytical study was conducted. Blood smear examinations conducted at all MCCSPs in Yunnan from 2008 to 2014 were analysed. A cross-sectional survey was conducted in 2014 to understand how the MCCSPs function and to elucidate the quality of the blood smear examinations that they conduct. RESULTS: Out of the surveyed MCCSPs, 66 % (39/59), 22 % (13/59), and 12 % (7/59) were attached to local township hospitals, village health clinics, and the county centre for disease control and prevention or private clinics, respectively. More than 64 % (38/59) of the posts' staff were part-time workers from township hospitals and village health facilities. Less than 31 % (18/59) of the posts' staff were full time workers. A total of 35 positive malaria cases were reported from seven MCCSPs in 2014. Four MCCSPs were unable to perform their functions due to under staffing in 2014. There was a small fluctuation in blood smear examinations from January 2008 to June 2009, with two peaks during the period from July 2009 to October 2010. The number of blood smear examinations has been increasing since 2011. The yearly mean number of blood smear examinations in each post increased from 44 per month in 2011 to 109 per month in 2014, and the number of positive malaria cases detected by blood smear examinations has declined (chi 2 = 90.67, P = 0.000). The percentage of people from Yingjiang county getting blood smear examinations increased between 2008 and 2014, while percentages of the mobile population including Myanmar people, people from other provinces, and people from other Yunnan counties getting blood smear examinations decreased. CONCLUSION: MCCSPs face challenges in the phase of malaria elimination in Yunnan, China. New case detection strategies should be designed for MCCSPs taking into account the current trends of migration. PMID- 27716343 TI - High levels of biomarkers of collagen remodeling are associated with increased mortality in COPD - results from the ECLIPSE study. AB - BACKGROUND: There is a need to identify individuals with COPD at risk for disease progression and mortality. Lung tissue remodeling is associated with the release of extracellular matrix (ECM) fragments into the peripheral circulation. We hypothesized that ECM remodeling was associated with mortality in COPD and measured neo-epitopes originating from ECM proteins associated with lung tissue remodeling. METHODS: Biomarkers of ECM remodeling were assessed in a subpopulation (n = 1000) of the Evaluation of COPD Longitudinally to Identify Predictive Surrogate End-points (ECLIPSE) cohort. Validated immunoassays measuring serological neo-epitopes produced by proteolytic cleavage associated with degradation of collagen type I, III, IV, and VI, elastin, and biglycan, and formation of collagen type VI as well as fibrinogen and C-reactive protein were used. Multivariate models were used to assess the prognostic value of these biomarkers. RESULTS: Thirty subjects (3.0 %) died during follow-up. Non-survivors were older, had reduced exercise capacity, increased dyspnea score, and included fewer current smokers. All collagen biomarkers were significantly elevated in non survivors compared to survivors. Mortality risk was significantly increased for subjects with collagen remodeling biomarkers in the upper quartile, especially for the degradation fragment of collagen type IV C6M (hazard ratio 6.6 [95 % confidence interval 2.9-15.2], P < 0.0001) after adjusting for relevant confounders. CONCLUSIONS: Serological biomarkers of collagen remodeling were strongly associated with mortality in subjects with COPD indicating that assessment of tissue turnover in the parenchyma and small airways may be useful in the prognosis of COPD.

AB - BACKGROUND: T1 mapping based on cardiovascular magnetic resonance (CMR) is a novel approach using the magnetic relaxation T1 time as a quantitative marker for myocardial tissue composition. Various T1 mapping sequences are being used, with different strengths and weaknesses. Data comparing different sequences head to head however are sparse. METHODS: We compared three T1 mapping sequences, ShMOLLI, MOLLI and SASHA in phantoms and in a mid-ventricular slice of 40 healthy individuals (mean age 59 +/- 7 years, 45 % male) with low (68 %) or moderate cardiovascular risk. We calculated global and segmental T1 in vivo through exponential curve fitting and subsequent parametric mapping. We also analyzed image quality and inter-observer reproducibility. RESULTS: There was no association of T1 with cardiovascular risk groups. T1 however differed significantly depending on the sequence, with SASHA providing consistently higher mean values than ShMOLLI and MOLLI (1487 +/- 36 ms vs. 1174 +/- 37 ms and 1199 +/ 28 ms, respectively; p < 0.001). This difference between sequences was much smaller in phantom measurements. In patients, segmental values were lower in the anterior wall for all sequences. Image quality, in general good for the steady state-free-precession readouts in all sequences, was lower for SASHA parametric maps. On multivariate regression analysis, a longer T1 measured by MOLLI was correlated with lower ejection fraction and female gender. Inter-observer variability as assessed by intra-class correlation coefficients was excellent for all sequences (ShMOLLI: 0.995; MOLLI: 0.991; SASHA: 0.961; all p < 0.001). CONCLUSION: In a cross-sectional population with low to moderate cardiovascular risk, we observed a variation in T1 mapping results between inversion-recovery vs. saturation-recovery sequences in vivo, which were less evident in phantom images, despite a small interobserver variability. Thus, physiological factors, most likely related to B1 inhomogeneities, and tissue-specific properties, like magnetization transfer, that impact T1 values in vivo, render phantom validation insufficient, and have to be further investigated for a better understanding of the clinical utility of different T1 mapping approaches.

PMID- 27716345 TI - Dissection of exopolysaccharide biosynthesis in Kozakia baliensis. AB - BACKGROUND: Acetic acid bacteria (AAB) are well known producers of commercially used exopolysaccharides, such as cellulose and levan. Kozakia (K.) baliensis is a relatively new member of AAB, which produces ultra-high molecular weight levan from sucrose. Throughout cultivation of two K. baliensis strains (DSM 14400, NBRC 16680) on sucrose-deficient media, we found that both strains still produce high amounts of mucous, water-soluble substances from mannitol and glycerol as (main) carbon sources. This indicated that both Kozakia strains additionally produce new classes of so far not characterized EPS. RESULTS: By whole genome sequencing of both strains, circularized genomes could be established and typical EPS forming clusters were identified. As expected, complete ORFs coding for levansucrases could be detected in both Kozakia strains. In K. baliensis DSM 14400 plasmid encoded cellulose synthase genes and fragments of truncated levansucrase operons could be assigned in contrast to K. baliensis NBRC 16680. Additionally, both K. baliensis strains harbor identical gum-like clusters, which are related to the well characterized gum cluster coding for xanthan synthesis in Xanthomanas campestris and show highest similarity with gum-like heteropolysaccharide (HePS) clusters from other acetic acid bacteria such as Gluconacetobacter diazotrophicus and Komagataeibacter xylinus. A mutant strain of K. baliensis NBRC 16680 lacking EPS production on sucrose-deficient media exhibited a transposon insertion in front of the gumD gene of its gum-like cluster in contrast to the wildtype strain, which indicated the essential role of gumD and of the associated gum genes for production of these new EPS. The EPS secreted by K. baliensis are composed of glucose, galactose and mannose, respectively, which is in agreement with the predicted sugar monomer composition derived from in silico genome analysis of the respective gum-like clusters. CONCLUSIONS: By comparative sugar monomer and genome analysis, the polymeric substances secreted by K. baliensis can be considered as unique HePS. Via genome sequencing of K. baliensis DSM 14400 + NBRC 16680 we got first insights into the biosynthesis of these novel HePS, which is related to xanthan and acetan biosynthesis. Consequently, the present study provides the basis for establishment of K. baliensis strains as novel microbial cell factories for biotechnologically relevant, unique polysaccharides. PMID- 27716347 TI - Assessing the external validity of algorithms to estimate EQ-5D-3L from the WOMAC. AB - BACKGROUND: The use of mapping algorithms have been suggested as a solution to predict health utilities when no preference-based measure is included in the study. However, validity and predictive performance of these algorithms are highly variable and hence assessing the accuracy and validity of algorithms before use them in a new setting is of importance. The aim of the current study was to assess the predictive accuracy of three mapping algorithms to estimate the EQ-5D-3L from the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) among Swedish people with knee disorders. Two of these algorithms developed using ordinary least squares (OLS) models and one developed using mixture model. METHODS: The data from 1078 subjects mean (SD) age 69.4 (7.2) years with frequent knee pain and/or knee osteoarthritis from the Malmo Osteoarthritis study in Sweden were used. The algorithms' performance was assessed using mean error, mean absolute error, and root mean squared error. Two types of prediction were estimated for mixture model: weighted average (WA), and conditional on estimated component (CEC). RESULTS: The overall mean was overpredicted by an OLS model and underpredicted by two other algorithms (P < 0.001). All predictions but the CEC predictions of mixture model had a narrower range than the observed scores (22 to 90 %). All algorithms suffered from overprediction for severe health states and underprediction for mild health states with lesser extent for mixture model. While the mixture model outperformed OLS models at the extremes of the EQ-5D-3D distribution, it underperformed around the center of the distribution. CONCLUSIONS: While algorithm based on mixture model reflected the distribution of EQ-5D-3L data more accurately compared with OLS models, all algorithms suffered from systematic bias. This calls for caution in applying these mapping algorithms in a new setting particularly in samples with milder knee problems than original sample. Assessing the impact of the choice of these algorithms on cost-effectiveness studies through sensitivity analysis is recommended. PMID- 27716346 TI - Fundamentals of aerosol therapy in critical care. AB - Drug dosing in critically ill patients is challenging due to the altered drug pharmacokinetics-pharmacodynamics associated with systemic therapies. For many drug therapies, there is potential to use the respiratory system as an alternative route for drug delivery. Aerosol drug delivery can provide many advantages over conventional therapy. Given that respiratory diseases are the commonest causes of critical illness, use of aerosol therapy to provide high local drug concentrations with minimal systemic side effects makes this route an attractive option. To date, limited evidence has restricted its wider application. The efficacy of aerosol drug therapy depends on drug-related factors (particle size, molecular weight), device factors, patient-related factors (airway anatomy, inhalation patterns) and mechanical ventilation-related factors (humidification, airway). This review identifies the relevant factors which require attention for optimization of aerosol drug delivery that can achieve better drug concentrations at the target sites and potentially improve clinical outcomes. PMID- 27716348 TI - Whole-body patterns of the range of joint motion in young adults: masculine type and feminine type. AB - BACKGROUND: Understanding the whole-body patterns of joint flexibility and their related biological and physical factors contributes not only to clinical assessments but also to the fields of human factors and ergonomics. In this study, ranges of motion (ROMs) at limb and trunk joints of young adults were analysed to understand covariation patterns of different joint motions and to identify factors associated with the variation in ROM. METHODS: Seventy-eight healthy volunteers (42 males and 36 females) living on Okinawa Island, Japan, were recruited. Passive ROM was measured at multiple joints through the whole body (31 measurements) including the left and right side limbs and trunk. RESULTS: Comparisons between males and females, dominant and non-dominant sides, and antagonistic motions indicated that body structures influence ROMs. In principal component analysis (PCA) on the ROM data, the first principal component (PC1) represented the sex difference and a similar covariation pattern appeared in the analysis within each sex. Multiple regression analysis showed that this component was associated with sex, age, body fat %, iliospinale height, and leg extension strength. CONCLUSIONS: The present study identified that there is a spectrum of "masculine" and "feminine" types in the whole-body patterns of joint flexibility. This study also suggested that body proportion and composition, muscle mass and strength, and possibly skeletal structures partly explain such patterns. These results would be important to understand individual variation in susceptibility to joint injuries and diseases and in one's suitable and effective postures and motions. PMID- 27716349 TI - Reduced volume SIB-IMRT/IGRT to head and neck cancer in elderly and frail patients: outcome and toxicity. AB - BACKGROUND: Especially elderly and frail patients have a limited ability to compensate for side effects of a radical treatment of head and neck malignancies. Limiting the target volume to the macroscopic disease, without prophylactic nodal irradiation, might present a feasible approach for these patients. The present work therefore aims evaluating an IMRT/IGRT -SIB concept for safety and efficacy. METHODS: The study retrospectively enrolled 27 patients with head and neck cancers treated between 01/2012 and 05/2015. We evaluated patient files for clinical status, concomitant diseases, treatment side, and treatment volumes as well as for side effects and tumor responses. To describe efficacy and risk factors for worse outcome and higher grade toxicities, we performed cox regression analysis as well as Kaplan-Meier survival time analysis. RESULTS: Median survival was 181 days, 75 % patients showed an early local response at six weeks of follow up. Most patients developed mild to moderate acute toxicities, only one patient with grade IV mucositis was seen. The grade of toxicities was correlated to the size of the PTV. Concomitant diseases, metastatic disease, and G3 Grading were indicators for worse prognosis. CONCLUSION: The IMRT/IGRT SIB concept is a safe and feasible radiotherapy concept for patients not able or not willing to undergo radical treatment. PMID- 27716350 TI - Opportunities and obstacles to the development of nanopharmaceuticals for human use. AB - Pharmaceutical nanotechnology has generated breakthrough developments in improving health care and human life from its emergence. The biomaterials employed mainly aim at improving drug delivery systems, imaging and diagnostic technologies while the nanoscale materials are in widespread use in other industries such as electronics and optics. Such advancement may revolutionize the drug development and therapy with new and more efficient treatments. Although, nanotechnology assists humankind in improving its well being, it has certain limitations that entail thorough investigation by the regulatory and scientific authorities. To address concerns regarding the safety and toxicity profile of the nanopharmaceuticals, we have reviewed the challenges and solutions of nanopharmaceuticals use in human health and the related health risks. In this regard, regulatory and scientific bodies such as countries' Food and Drug Administration (FDA), Organization for Economic Co-operation and Development (OECD), European Medicine Agency (EMA), Environmental Protection Agency (EPA), National Institute for Occupational Safety and Health (NIOSH), and World Health Organization (WHO) can participate in developing and reinforcing safety measures and regulatory frameworks to insure the public health. The regulatory authorities may enforce the nanopharmaceutical industries to conduct comprehensive toxicity tests and monitor the adverse drug reaction reports in close collaboration with the scientific community to act accordingly and inform the public as the implementation of the strategy. Nanopharmaceuticals have tremendous potential for human use as therapeutic or diagnostic agents. But their toxicity profile should be well addressed and the respective regulatory framework developed and reinforced by the authorities. PMID- 27716351 TI - Does the optimal position of the acetabular fragment should be within the radiological normal range for all developmental dysplasia of the hip? A patient specific finite element analysis. AB - BACKGROUND: The success of Bernese periacetabular osteotomy depends significantly on how extent the acetabular fragment can be corrected to its optimal position. This study was undertaken to investigate whether correcting the acetabular fragment into the so-called radiological "normal" range is the best choice for all developmental dysplasia of the hip with different severities of dysplasia from the biomechanical view? If not, is there any correlation between the biomechanically optimal position of the acetabular fragment and the severity of dysplasia? METHODS: Four finite element models with different severities of dysplasia were developed. The virtual periacetabular osteotomy was performed with the acetabular fragment rotated anterolaterally to incremental center-edge angles; then, the contact area and pressure and von Mises stress in the cartilage were calculated at different correction angles. RESULTS: The optimal position of the acetabular fragment for patients 1, 2, and 3 was when the acetabular fragment rotated 17 degrees laterally (with the lateral center-edge angle of 36 degrees and anterior center-edge angle of 58 degrees ; both were slightly larger than the "normal" range), 25 degrees laterally following further 5 degrees anterior rotation (with the lateral center-edge angle of 31 degrees and anterior center edge angle of 51 degrees ; both were within the "normal" range), and 30 degrees laterally following further 10 degrees anterior rotation (with the lateral center-edge angle of 25 degrees and anterior center-edge angle of 40 degrees ; both were less than the "normal" range), respectively. CONCLUSIONS: The optimal corrective position of the acetabular fragment is severity dependent rather than within the radiological "normal" range for developmental dysplasia of the hip. We prudently proposed that the optimal correction center-edge angle of mild, moderate, and severe developmental dysplasia of the hip is slightly larger than the "normal" range, within the "normal" range, and less than the lower limit of the "normal" range, respectively. PMID- 27716352 TI - Integrating one health in national health policies of developing countries: India's lost opportunities. AB - BACKGROUND: Globally, the threat of infectious diseases, particularly emerging infectious diseases, originating at the human-animal-environment interface, has caught health systems off guard. With forecasts that future pathogen emergence will be centred in hotspots in Asia, Africa, and Latin America, the need to prepare policy frameworks that can combat this threat is urgent. DISCUSSION: Emergence of diseases such as avian influenza and Ebola virus disease, which threatened social disruption, have established the need for intersectoral coordination/collaboration. These events led to the initiation of establishing institutionalised collaborative frameworks in India to adopt a One Health approach to disease prevention and control. However, the gains made in influenza control could not be adapted to other infectious diseases. Intersectoral coordination was briefly carried out, more as a reactive response to threats. The systemic failure to sustain such efforts have therefore, only undermined a coordinated response. The recent draft National Health Policy, 2015, has also failed to establish the need for intersectoral coordination in disease control approaches. Neglecting the need to endorse linkages between human health, animal health and husbandry, agriculture, and environmental sectors, has led to duplicative and weak response systems. The absence of health impact assessment with respect to the development agenda in policies, has cast negative effects on the health and wellbeing of man, animal, and the environment. Lack of attention to building core capacity in these critical sectors has further raised challenges in designing and deploying mitigation strategies. With developing countries like India being home to a major portion of the world's poorest livestock farmers, the absence of a policy discourse that endorses the One Health approach in development and health policies is a major hurdle in eliminating poverty and poverty-related diseases. CONCLUSIONS: The adoption of One Health approaches in health and related sectoral policies is a critical policy requirement for India and other developing countries. The goal should be to not just establish preparedness plans, but also to encourage a policy environment where assessment and mitigation of downstream impacts of different agenda are incorporated. PMID- 27716354 TI - Accuracy of p57KIP2 compared with genotyping for the diagnosis of complete hydatidiform mole: protocol for a systematic review and meta-analysis. AB - BACKGROUND: Distinguishing hydatidiform moles (HMs) from non-molar specimens and the subclassification of HM are important because complete hydatidiform mole (CHM) is associated with an increased risk of gestational trophoblastic neoplasia. However, diagnosis based solely on morphology has poor interobserver reproducibility. Recent studies have demonstrated that the use of p57KIP2 immunostaining improves diagnostic accuracy for CHM. METHODS: We will conduct a systematic review of prospective and retrospective studies to evaluate the accuracy of p57KIP2 immunostaining compared with molecular genotyping for the diagnosis of CHM. A high-sensitivity search strategy will be employed in MEDLINE, EMBASE, LILACS, The Grey Literature Report, OpenGrey, OAIster, and Cochrane CENTRAL. Two reviewers will independently screen all identified references for eligibility and extract data. The methodological quality and bias of the included studies will be assessed according to the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool, and the overall quality of evidence will be assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. If a meta-analysis is possible, pooled estimates of sensitivity, specificity, and positive and negative likelihood ratios will be calculated using bivariate random-effects models. Statistical heterogeneity will be evaluated with I 2 statistics and explored through sensitivity analysis. DISCUSSION: There is considerable overlap between the histological features of molar and non-molar pregnancies and between complete and partial HMs, which results in significant interobserver variability in the diagnosis of CHM and its mimics. Therefore, molecular techniques are used to correctly diagnosis and treat CHM. However, these molecular diagnostic methods are technically difficult to perform, relatively costly, and unavailable in most pathology laboratories. According to our results, p57KIP2 immunostaining appears to be a practical and accurate adjunct for the diagnosis of CHM and its mimics because this technique is relatively simple, reliable, cost-efficient, and rapid. This systematic review will help to determine whether p57KIP2 immunostaining is an adequate alternative diagnostic test for CHM. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42015024181. PMID- 27716353 TI - The risks of overlooking the diagnosis of secreting pituitary adenomas. AB - Secreting pituitary adenomas that cause acromegaly and Cushing's disease, as well as prolactinomas and thyrotroph adenomas, are uncommon, usually benign, slow growing tumours. The rarity of these conditions means that their diagnosis is not familiar to most non-specialist physicians. Consequently, pituitary adenomas may be overlooked and remain untreated, and affected individuals may develop serious comorbidities that reduce their quality of life and life expectancy. Because many signs and symptoms of pituitary adenomas overlap with those of other, more common disorders, general practitioners and non-endocrinology specialists need to be aware of the "red flags" suggestive of these conditions. A long duration of active disease in patients with secreting pituitary adenomas is associated with an increased risk of comorbidities and reduced quality of life. Appropriate treatment can lead to disease remission, and, although some symptoms may persist in some patients, treatment usually reduces the incidence and severity of comorbidities and improves quality of life. Therefore, correct, early diagnosis and characterization of a pituitary adenoma is crucial for patients, to trigger timely, appropriate treatment and to optimize outcome. This article provides an overview of the epidemiology of hormonal syndromes associated with pituitary adenomas, discusses the difficulties of and considerations for their diagnosis, and reviews the comorbidities that may develop, but can be prevented, by accurate diagnosis and appropriate treatment. We hope this review will help general practitioners and non-endocrinology specialists to suspect secreting pituitary adenomas and refer patients to an endocrinologist for confirmation of the diagnosis and treatment. PMID- 27716355 TI - Use of explicit ICD9-CM codes to identify adult severe sepsis: impacts on epidemiological estimates. AB - BACKGROUND: Severe sepsis is a challenge for healthcare systems, and epidemiological studies are essential to assess its burden and trends. However, there is no consensus on which coding strategy should be used to reliably identify severe sepsis. This study assesses the use of explicit codes to define severe sepsis and the impacts of this on the incidence and in-hospital mortality rates. METHODS: We examined episodes of severe sepsis in adults aged >=18 years registered in the 2006-2011 national hospital discharge database, identified in an exclusive manner by two ICD-9-CM coding strategies: (1) those assigned explicit ICD-9-CM codes (995.92, 785.52); and (2) those assigned combined ICD-9 CM infection and organ dysfunction codes according to modified Martin criteria. The coding strategies were compared in terms of the populations they defined and their relative implementation. Trends were assessed using Joinpoint regression models and expressed as annual percentage change (APC). RESULTS: Of 222 846 episodes of severe sepsis identified, 138 517 (62.2 %) were assigned explicit codes and 84 329 (37.8 %) combination codes; incidence rates were 60.6 and 36.9 cases per 100 000 inhabitants, respectively. Despite similar demographic characteristics, cases identified by explicit codes involved fewer comorbidities, fewer registered pathogens, greater extent of organ dysfunction (two or more organs affected in 60 % versus 26 % of cases) and higher in-hospital mortality (54.5 % versus 29 %; risk ratio 1.86, 95 % CI 1.83, 1.88). Between 2006 and 2011, explicit codes were increasingly implemented. Standardised incidence rates in this cohort increased over time with an APC of 12.3 % (95 % CI 4.4, 20.8); in the combination code cohort, rates increased by 3.8 % (95 % CI 1.3, 6.3). A decreasing trend in mortality was observed in both cohorts though the APC was 8.1 % (95 % CI -10.4, -5.7) in the combination code cohort and -3.5 % (95 % CI 3.9, -3.2) in the explicit code cohort. CONCLUSIONS: Our findings suggest greater and increasing use of explicit codes for adult severe sepsis in Spain. This trend will have substantial impacts on epidemiological estimates, because these codes capture cases featuring greater organ dysfunction and in-hospital mortality. PMID- 27716356 TI - Exosomes derived from HCC cells induce sorafenib resistance in hepatocellular carcinoma both in vivo and in vitro. AB - BACKGROUND: Exosomes are carriers of intercellular information and regulate the tumor microenvironment. They play an important role in drug resistance by transporting RNA molecules and proteins. However, their effects on sorafenib resistance in hepatocellular carcinoma (HCC) are not completely understood. METHODS: Exosomes were isolated from two invasive hepatoma cell lines (MHCC-97 L and MHCC-97H), and their roles in regulating sorafenib resistance in liver cancer cells as well as the underlying molecular mechanisms were determined. The exosomes were analyzed by TEM (transmission electron microscopy), DLS (dynamic light scattering) and Western blotting. Cell viability, cell death and the effects of exosomes on the HGF/c-Met/Akt signaling pathway in cancer cells were analyzed by MTT assays, FACS analysis and Western blotting, respectively. Moreover, the effects of exosomes on sorafenib resistance in vivo were investigated using a subcutaneous transplantation tumor model in athymic nude mice. RESULTS: Exosomes derived from HCC cells were of the expected size and expressed the exosomal markers CD9 and CD63. They induced sorafenib resistance in vitro by activating the HGF/c-Met/Akt signaling pathway and inhibiting sorafenib induced apoptosis. They also induced sorafenib resistance in vivo by inhibiting sorafenib-induced apoptosis. Moreover, exosomes derived from highly invasive tumor cells had greater efficacy than that of exosomes derived from less invasive cells. CONCLUSIONS: These data reveal the important role of HCC cell-derived exosomes in the drug resistance of liver cancer cells and demonstrate the intrinsic interaction between exosomes and their targeted tumor cells. This study suggests a new strategy for improving the effectiveness of sorafenib in treating HCC.

PMID- 27716357 TI - How best to structure interdisciplinary primary care teams: the study protocol for a systematic review with narrative framework synthesis. AB - BACKGROUND: Western publicly funded health care systems increasingly rely on interdisciplinary teams to support primary care delivery and management of chronic conditions. This knowledge synthesis focuses on what is known in the academic and grey literature about optimal structural characteristics of teams. Its goal is to assess which factors contribute to the effective functioning of interdisciplinary primary care teams and improved health system outcomes, with specific focus on (i) team structure contribution to team process, (ii) team process contribution to primary care goals, and (iii) team structure contribution to primary care goals. METHODS AND DESIGN: The systematic search of academic literature focuses on four chronic conditions and co-morbidities. Within this scope, qualitative and quantitative studies that assess the effects of team characteristics (funding, governance, organization) on care process and patient outcomes will be searched. Electronic databases (Ovid MEDLINE, Embase, CINAHL, PAIS, Web of Science) will be searched systematically. Online web-based searches will be supported by the Grey Matters Tool. Studies will be included, if they report on interdisciplinary primary care in publicly funded Western health systems, and address the relationships between team structure, process, and/or patient outcomes. Studies will be selected in a three-stage screening process (title/abstract/full text) by two independent reviewers in each stage. Study quality will be assessed using the Mixed Methods Assessment Tool. An a priori framework will be applied to data extraction, and a narrative framework approach is used for the synthesis. DISCUSSION: Using an integrated knowledge translation approach, an electronic decision support tool will be developed for decision makers. It will be searchable along two axes of inquiry: (i) what primary care goals are supported by specific team characteristics and (ii) how should teams be structured to support specific primary care goals? The results of this evidence review will contribute directly to the design of interdisciplinary primary care teams. The optimized design will support the goals of primary care, contributing to the improved health of populations. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016041884. PMID- 27716359 TI - TrhOnt: building an ontology to assist rehabilitation processes. AB - BACKGROUND: One of the current research efforts in the area of biomedicine is the representation of knowledge in a structured way so that reasoning can be performed on it. More precisely, in the field of physiotherapy, information such as the physiotherapy record of a patient or treatment protocols for specific disorders must be adequately modeled, because they play a relevant role in the management of the evolutionary recovery process of a patient. In this scenario, we introduce TRHONT, an application ontology that can assist physiotherapists in the management of the patients' evolution via reasoning supported by semantic technology. METHODS: The ontology was developed following the NeOn Methodology. It integrates knowledge from ontological (e.g. FMA ontology) and non-ontological resources (e.g. a database of movements, exercises and treatment protocols) as well as additional physiotherapy-related knowledge. RESULTS: We demonstrate how the ontology fulfills the purpose of providing a reference model for the representation of the physiotherapy-related information that is needed for the whole physiotherapy treatment of patients, since they step for the first time into the physiotherapist's office, until they are discharged. More specifically, we present the results for each of the intended uses of the ontology listed in the document that specifies its requirements, and show how TRHONT can answer the competency questions defined within that document. Moreover, we detail the main steps of the process followed to build the TRHONT ontology in order to facilitate its reproducibility in a similar context. Finally, we show an evaluation of the ontology from different perspectives. CONCLUSIONS: TRHONT has achieved the purpose of allowing for a reasoning process that changes over time according to the patient's state and performance. PMID- 27716360 TI - Differences in joint morphology between the knee and ankle affect the repair of osteochondral defects in a rabbit model. AB - BACKGROUND: Although differences in the results of the bone marrow stimulation technique between the knee and ankle have been reported, a detailed mechanism for those differences has not been clarified. The purpose of this study was to examine whether morphological differences between the knee and ankle joint affect the results of drilling as treatment for osteochondral defects in a rabbit model. METHODS: Osteochondral defects were created at the knee and ankle joint in the rabbit. In the knee, osteochondral defects were created at the medial femoral condyle (MFC) and patellar groove (PG). At the ankle, defects were created in the talus at either a covered or uncovered area by the tibial plafond. After creating the osteochondral defect, drilling was performed. At 4, 8, and 12 weeks after surgery, repair of the osteochondral defects were evaluated histologically. The proliferation of rabbit chondrocytes and proteoglycan release of cartilage tissue in response to IL-1beta were analyzed in vitro in both joints. RESULTS: At 8 weeks after surgery, hyaline cartilage repair was observed in defects at the covered area of the talus and the MFC. At 12 weeks, hyaline cartilage with a normal thickness was observed for the defect at the covered area of the talus, but not for the defect at the MFC. At 12 weeks, subchondral bone formation progressed and a normal contour of subchondral bone was observed on CT in the defect at the covered area of the talus. No significant differences in chondrocyte proliferation rate and proteoglycan release were detected between the knee and ankle in vitro. CONCLUSIONS: Our results demonstrate that the covered areas of the talus show early and sufficient osteochondral repair compared to that of the knee and the uncovered areas of the talus. These results suggest that the congruent joint shows better subchondral repair prior to cartilage repair compared to that of the incongruent joint.

PMID- 27716361 TI - Long non-coding RNA H19 regulates FOXM1 expression by competitively binding endogenous miR-342-3p in gallbladder cancer. AB - BACKGROUND: Long non-coding RNA (lncRNA) H19 has been reported to involve in many kinds of human cancers and functions as an oncogene. Our previous study found that H19 was over-expressed in gallbladder cancer (GBC) and was shown to promote tumor development in GBC. However, the competing endogenous RNA (ceRNA) regulatory network involving H19 in GBC progression has not been fully elucidated. We aim to detect the role of H19 as a ceRNA in GBC. METHODS AND RESULTS: In this study, the expression of H19 and miR-342-3p were analyzed in 35 GBC tissues and matched normal tissues by using quantitative polymerase chain reaction (qRT-PCR). We demonstrated H19 was overexpressed and negatively correlated with miR-342-3p in GBC. By dual-luciferase reporter assays, RNA binding protein immunoprecipitation (RIP) and RNA pull-down assays, we verified that H19 was identified as a direct target of miR-342-3p. QRT-PCR and Western blotting assays demonstrated that H19 silencing down-regulated, whereas over expression enhanced the expression of miR-342-3p targeting FOXM1 through competitively 'sponging' miR-342-3p. Furthermore, transwell invasion assays and cell cycle assays indicated that H19 knockdown inhibited both cells invasion and proliferation, but this effects was attenuated by co-transfection of siRNA-H19 and miR-342-3p inhibitor in GBC cells. In vivo, tumor volumes were decreased significantly in H19 silenced group compared to the control group, but was attenuated by co-transfection of shRNA-H19 and miR-342-3p inhibitor, which were stablely constructed through lenti-virus vector. CONCLUSION: Our results suggest a potential ceRNA regulatory network involving H19 regulates FOXM1 expression by competitively binding endogenous miR-342-3p in GBC. This mechanism may contribute to a better understanding of GBC pathogenesis and provides potential therapeutic strategy for GBC. PMID- 27716363 TI - Hyperchloremia is associated with 30-day mortality in major trauma patients: a retrospective observational study. AB - BACKGROUND: Chloride is important for maintaining acid-base balance, muscular activity, osmosis and immunomodulation. In patients with major trauma, chloride levels increase after fluid therapy; this is associated with poor clinical outcomes. The purpose of this study was to determine whether hyperchloremia was associated with increased mortality in patients who had sustained major trauma. METHODS: This study enrolled 266 major trauma patients by retrospective chart review, from January 2011 to December 2015. Patients were older than 16 years; were admitted to an intensive care unit; survived more than 48 h; and had sustained major trauma, defined as an injury severity score >= 16. Hyperchloremia was defined as a chloride level > 110mEq/L. Delta chloride (Deltachloride) was defined as the difference between the serum chloride level measured 48-h post admission and the initial level. Clinical and laboratory variables were compared between survivors (n = 235) and non-survivors (n = 31). A multivariate logistic regression analysis was performed to assess the association between hyperchloremia 48-h post-admission (hyperchloremia-48) and 30-day mortality. RESULTS: The overall 30-day mortality was 11.7 % (n = 31). Hyperchloremia-48 occurred in 65 patients (24.4 %) and the incidence was significantly different between survivors and non-survivors (19.6 vs. 61.3 %, respectively, p < 0.001). Multivariate logistic analysis identified hyperchloremia-48 and Deltachloride as independent predictive factors for 30-day mortality in major trauma patients. DISCUSSION: Infusion of chloride-rich solutions, such as normal saline, is itself associated with hyperchloremia, which has been associated with poor patient outcomes. Patients receiving normal saline were more likely to suffer major postoperative complications, acute kidney injury, and infections. Moreover, large changes in serum chloride levels correlated with greater in-hospital mortality. CONCLUSION: Hyperchloremia 48-h post-admission and Deltachloride was associated with 30-day mortality in major trauma patients. These indices may be useful prognostic markers. PMID- 27716364 TI - Development and validation of a survey to measure features of clinical networks. AB - BACKGROUND: Networks of clinical experts are increasingly being implemented as a strategy to improve health care processes and outcomes and achieve change in the health system. Few are ever formally evaluated and, when this is done, not all networks are equally successful in their efforts. There is a need to formatively assess the strategic and operational management and leadership of networks to identify where functioning could be improved to maximise impact. This paper outlines the development and psychometric evaluation of an Internet survey to measure features of clinical networks and provides descriptive results from a sample of members of 19 diverse clinical networks responsible for evidence-based quality improvement across a large geographical region. METHODS: Instrument development was based on: a review of published and grey literature; a qualitative study of clinical network members; a program logic framework; and consultation with stakeholders. The resulting domain structure was validated for a sample of 592 clinical network members using confirmatory factor analysis. Scale reliability was assessed using Cronbach's alpha. A summary score was calculated for each domain and aggregate level means and ranges are reported. RESULTS: The instrument was shown to have good construct validity across seven domains as demonstrated by a high level of internal consistency, and all Cronbach's alpha coefficients were equal to or above 0.75. In the survey sample of network members there was strong reported commitment and belief in network-led quality improvement initiatives, which were perceived to have improved quality of care (72.8 %) and patient outcomes (63.2 %). Network managers were perceived to be effective leaders and clinical co-chairs were perceived as champions for change. Perceived external support had the lowest summary score across the seven domains. CONCLUSIONS: This survey, which has good construct validity and internal reliability, provides a valid instrument to use in future research related to clinical networks. The survey will be of use to health service managers to identify strengths and areas where networks can be improved to increase effectiveness and impact on quality of care and patient outcomes. Equally, the survey could be adapted for use in the assessment of other types of networks. PMID- 27716365 TI - Schistosomiasis vaccines: where do we stand? AB - Schistosomiasis, caused mainly by S. mansoni, S. haematobium and S. japonicum, continues to be a serious tropical disease and public health problem resulting in an unacceptably high level of morbidity in countries where it is endemic. Praziquantel, the only drug currently available for treatment, is unable to kill developing schistosomes, it does not prevent re-infection and its continued extensive use may result in the future emergence of drug-resistant parasites. This scenario provides impetus for the development and deployment of anti schistosome vaccines to be used as part of an integrated approach for the prevention, control and eventual elimination of schistosomiasis. This review considers the present status of candidate vaccines for schistosomiasis, and provides some insight on future vaccine discovery and design. PMID- 27716366 TI - The effect of n-3/n-6 polyunsaturated fatty acids on acute reflux esophagitis in rats. AB - BACKGROUND: Polyunsaturated fatty acids (PUFAs) play various roles in inflammation. However, the effect of PUFAs in the development of reflux esophagitis (RE) is unclear. This study is to investigate the potential effect of n-3/n-6 PUFAs on acute RE in rats along with the underlying protective mechanisms. METHODS: Forty Sprague Dawley rats were randomly divided into four groups (n = 10 in each group). RE model was established by pyloric clip and section ligation. Fish oil- and soybean oil-based fatty emulsion (n-3 and n-6 groups), or normal saline (control and sham operation groups) was injected intraperitoneally 2 h prior to surgery and 24 h postoperatively (2 mL/kg, respectively). The expressions of interleukin (IL)-1beta, IL-8, IL-6 and myeloid differentiation primary response gene 88 (MyD88) in esophageal tissues were evaluated by Western blot and immunohistochemistry after 72 h. The malondialdehyde (MDA) and superoxide dismutase (SOD) expression in the esophageal tissues were determined to assess the oxidative stress. RESULTS: The mildest macroscopic/microscopic esophagitis was found in the n-3 group (P < 0.05). The expression of IL-1beta, IL-8, IL-6 and MyD88 were increased in all RE groups, while the lowest and highest expression were found in n-3 and n-6 group, respectively (P < 0.05). The MDA levels were increased in all groups (P < 0.05), in an ascending trend from n-3, n-6 groups to control group. The lowest and highest SOD levels were found in the control and n-3 group, respectively (P < 0.05). CONCLUSION: n-3 PUFAs may reduce acute RE in rats, which may be due to inhibition of the MyD88-NF-kB pathway and limit oxidative damage. PMID- 27716367 TI - SDF-1/CXCR7 axis regulates the proliferation, invasion, adhesion, and angiogenesis of gastric cancer cells. AB - BACKGROUND: More recent studies have revealed that chemokine receptor CXCR7 plays an important role in cancer development. However, little is known about the effect of CXCR7 on the process of gastric cancer cell invasion and angiogenesis. The aim of this study is to investigate the expression of CXCR7 in gastric cancer cell lines and to evaluate the role of CXCR7 in the proliferation, invasion, adhesion, and angiogenesis of gastric cancer cells. METHODS: Real-time PCR and Western blotting were used to examine the mRNA and protein levels of CXCR4 and CXCR7 in five gastric cancer cell lines (HGC-27, MGC-803, BGC-823, SGC-7901, and MKN-28). CXCR7-expressing shRNA was constructed and subsequently stably transfected into the human gastric cancer cells. In addition, the effect of CXCR7 inhibition on cell proliferation, invasion, adhesion, VEGF secretion, and tube formation was evaluated. RESULTS: The mRNA and protein of CXCR7 were expressed in all five gastric cancer cell lines; in particular, the expression of CXCR7 was the highest in SGC-7901 cells. Stromal cell-derived factor-1 (SDF-1) was found to induce proliferation, invasion, adhesion, and tube formation. Moreover, the VEGF secretion in SGC-7901 cells was also enhanced by SDF-1 stimulation. These biological effects were inhibited by the silencing of CXCR7 in SGC-7901 cells. CONCLUSIONS: Increased CXCR7 expression was found in gastric cancer cells. Knockdown of CXCR7 expression by transfection with CXCR7shRNA significantly inhibits SGC-7901 cells' proliferation, invasion, adhesion, and angiogenesis. This study provides new insights into the significance of CXCR7 in the invasion and angiogenesis of gastric cancer. PMID- 27716368 TI - A novel model for studying ileitis-induced visceral hypersensitivity in goats. AB - BACKGROUND: Visceral hypersensitivity (VH) is a common condition in many gastrointestinal disorders such as inflammatory bowel diseases (IBDs) in human and animals. Most studies often induce Crohn's disease/colitis to investigate VH in small experimental animals. Although farm animals commonly suffer from IBDs, their VH has not been investigated so far. Because goats can suffer from Johne's disease, a naturally occurring Crohn's-like disease, they may be suitable to be used for studying the mechanism underlying VH in common intestinal disorders of large animals. In the present study, 60 healthy goats of either sex were equally divided into a 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) group and saline group. A volume of 1.2 ml of TNBS-ethanol solution (30 mg TNBS in 40 % ethanol) or an equal volume of isotonic saline was injected into the wall of the terminal ileum through laparotomy. The severity of the developing ileitis was determined according to macro- and microscopic pathologic scores and the levels of myeloperoxidase, interleukin-1beta, interleukin-6 and tumor necrosis factor alpha, and VH was evaluated with visceromotor responses (VMR) to colorectal distension on days 3, 7, 14, 21 and 28. VMRs were assessed with a continuous ramp distention mode with 6 s for each pressure (20, 40, 60, 80 and 100 mmHg). RESULTS: Compared to the saline group, the TNBS-treated goats showed apparent transmural pathological changes and a significant increase (P < 0.05) in macroscopic and microscopic change scores, and levels of myeloperoxidase, interleukin-1beta, interleukin-6 and tumor necrosis factor-alpha in the ileum, and VMR to colorectal distension. The goats exhibited apparent ileitis at days 3 to 21, and VH at days 7 to 28 following TNBS treatment. CONCLUSION: This experiment successfully established a reproducible ileitis and VH with administration of TNBS-ethanol solution in the ileal wall of goats. This model is useful for studying the pathogenesis of the IBD and the mechanism underlying VH, and for evaluating the efficacy of new therapeutic regimens. PMID- 27716370 TI - Near-infrared spectroscopy for assessing tissue oxygenation and microvascular reactivity in critically ill patients: a prospective observational study. AB - BACKGROUND: Impaired microcirculatory perfusion and tissue oxygenation during critical illness are associated with adverse outcome. The aim of this study was to detect alterations in tissue oxygenation or microvascular reactivity and their ability to predict outcome in critically ill patients using thenar near-infrared spectroscopy (NIRS) with a vascular occlusion test (VOT). METHODS: Prospective observational study in critically ill adults admitted to a 12-bed intensive care unit (ICU) of a University Hospital. NIRS with a VOT (using a 40 % tissue oxygen saturation (StO2) target) was applied daily until discharge from the ICU or death. A group of healthy volunteers were evaluated in a single session. During occlusion, StO2 downslope was measured separately for the first (downslope 1) and last part (downslope 2) of the desaturation curve. The difference between downslope 2 and 1 was calculated (delta-downslope). The upslope and area of the hyperaemic phase (receive operating characteristic (ROC) area under the curve (AUC) of StO2) were calculated, reflecting microvascular reactivity. Outcomes were ICU and 90-day mortality. RESULTS: Patients (n = 89) had altered downslopes and upslopes compared to healthy volunteers (n = 27). Mean delta-downslope was higher in ICU non-survivors (2.8 (0.4, 3.8) %/minute versus 0.4 (-0.8, 1.8) in survivors, p = 0.004) and discriminated 90-day mortality (ROC AUC 0.72 (95 % confidence interval 0.59, 0.84)). ICU non-survivors had lower mean upslope (141 (75, 193) %/minute versus 185 (143, 217) in survivors, p = 0.016) and AUC StO2 (7.9 (4.3, 12.6) versus 14.5 (11.2, 21.3), p = 0.001). Upslope and AUC StO2 on admission were significant although weak predictors of 90-day mortality (ROC AUC = 0.68 (0.54, 0.82) and 0.70 (0.58, 0.82), respectively). AUC StO2 <= 6.65 (1st quartile) on admission was independently associated with higher 90-day mortality (hazard ratio 7.964 (95 % CI 2.211, 28.686)). The lowest upslope in the ICU was independently associated with survival after ICU discharge (odds ratio 0.970 (95 % CI 0.945, 0.996)). CONCLUSIONS: In critically ill patients, NIRS with a VOT enables identification of alterations in tissue oxygen extraction capacity and microvascular reactivity that can predict mortality.

PMID- 27716371 TI - The effect of suramin on inhibiting fibroblast proliferation and preventing epidural fibrosis after laminectomy in rats. AB - BACKGROUND: Epidural fibrosis often causes serious complications in patients after lumbar laminectomy and discectomy and is associated with the proliferation of fibroblasts. Suramin is known to have an obvious inhibitory effect on the coactions of many growth factors and their receptors, but little was previously known about the effect of suramin on fibroblast proliferation and the progress of epidural fibrosis. METHODS: We illustrated the effect of suramin on cultured fibroblasts of rats with different concentrations (0, 200, 400, 600 mg/l). The proliferation of suramin-treated fibroblasts was evaluated by CCK-8 and western blot analysis. Additionally, in a rat model of laminectomy, different concentrations of suramin (100, 200, and 300 mg/ml) and saline were applied to the laminectomy sites locally. The effect of suramin on preventing epidural fibrosis was detected by the Rydell classification, hydroxyproline content, histological analysis, and collagen density analyses. RESULTS: The results of CCK 8 shown that suramin could significantly inhibit fibroblasts proliferation in a dose-dependent manner. The western blotting shown that the expression levels of the cell proliferation markers such as cyclin D1, cyclin E, and PCNA were down regulated. Moreover, in a rat model, we found that suramin could reduce epidural fibrosis as well as inhibit fibroblast proliferation, and 300 mg/ml suramin had better effect. CONCLUSIONS: Topical application of suramin could reduce epidural fibrosis after laminectomy, and the application of suramin could inhibit the proliferation of fibroblasts in rats. This study indicates that suramin is a potent antifibrotic agent that may have therapeutic potential for patients with epidural fibrosis. PMID- 27716369 TI - Patient survival and tumor characteristics associated with CHEK2:p.I157T - findings from the Breast Cancer Association Consortium. AB - BACKGROUND: P.I157T is a CHEK2 missense mutation associated with a modest increase in breast cancer risk. Previously, another CHEK2 mutation, the protein truncating c.1100delC has been associated with poor prognosis of breast cancer patients. Here, we have investigated patient survival and characteristics of breast tumors of germ line p.I157T carriers. METHODS: We included in the analyses 26,801 European female breast cancer patients from 15 studies participating in the Breast Cancer Association Consortium. We analyzed the association between p.I157T and the clinico-pathological breast cancer characteristics by comparing the p.I157T carrier tumors to non-carrier and c.1100delC carrier tumors. Similarly, we investigated the p.I157T associated risk of early death, breast cancer-associated death, distant metastasis, locoregional relapse and second breast cancer using Cox proportional hazards models. Additionally, we explored the p.I157T-associated genomic gene expression profile using data from breast tumors of 183 Finnish female breast cancer patients (ten p.I157T carriers) (GEO: GSE24450). Differential gene expression analysis was performed using a moderated t test. Functional enrichment was investigated using the DAVID functional annotation tool and gene set enrichment analysis (GSEA). The tumors were classified into molecular subtypes according to the St Gallen 2013 criteria and the PAM50 gene expression signature. RESULTS: P.I157T was not associated with increased risk of early death, breast cancer-associated death or distant metastasis relapse, and there was a significant difference in prognosis associated with the two CHEK2 mutations, p.I157T and c.1100delC. Furthermore, p.I157T was associated with lobular histological type and clinico-pathological markers of good prognosis, such as ER and PR expression, low TP53 expression and low grade. Gene expression analysis suggested luminal A to be the most common subtype for p.I157T carriers and CDH1 (cadherin 1) target genes to be significantly enriched among genes, whose expression differed between p.I157T and non-carrier tumors. CONCLUSIONS: Our analyses suggest that there are fundamental differences in breast tumors of CHEK2:p.I157T and c.1100delC carriers. The poor prognosis associated with c.1100delC cannot be generalized to other CHEK2 mutations. PMID- 27716372 TI - Should we treat pyrexia? And how do we do it? AB - The concept of pyrexia as a protective physiological response to aid in host defence has been challenged with the awareness of the severe metabolic stress induced by pyrexia. The host response to pyrexia varies, however, according to the disease profile and severity and, as such, the management of pyrexia should differ; for example, temperature control is safe and effective in septic shock but remains controversial in sepsis. From the reported findings discussed in this review, treating pyrexia appears to be beneficial in septic shock, out of hospital cardiac arrest and acute brain injury.Multiple therapeutic options are available for managing pyrexia, with precise targeted temperature management now possible. Notably, the use of pharmacotherapy versus surface cooling has not been shown to be advantageous. The importance of avoiding hypothermia in any treatment strategy is not to be understated.Whilst a great deal of progress has been made regarding optimal temperature management in recent years, further studies will be needed to determine which patients would benefit the most from control of pyrexia and by which means this should be implemented. This narrative review is part of a series on the pathophysiology and management of pyrexia. PMID- 27716373 TI - Real-time point of care microcirculatory assessment of shock: design, rationale and application of the point of care microcirculation (POEM) tool. AB - BACKGROUND: Despite over a decade of research and technological advances, sublingual microcirculatory monitoring has not yet reached clinical utility. Offline analysis is time consuming and occurs away from the patient. A system to assess the microcirculation at the point of care is desirable. We present a novel 5-point grading system (the point of care microcirculation (POEM) scoring system) that can be used at the point of care during non-invasive sublingual microcirculatory monitoring. METHODS: The POEM score is an ordinal scale from 1 (worst) to 5 (best), based on a composite assessment of flow and heterogeneity of four individual sublingual video-microscopy clips. Thirty-two healthcare professionals were trained in how to assign POEM scores. Following training they assigned scores to five test sequences (each consisting of four video clips). They were blinded to clinical status. Inter-user consistency and agreement were assessed using intra-class correlation coefficient (ICC) analysis. In addition, blinded expert scores for 68 video clips were compared to offline computer analysis using traditional microcirculatory parameters including total vessel density (TVD), perfused vessel density (PVD), proportion of perfused vessels (PPV), microcirculatory flow index (MFI) and microcirculatory heterogeneity index (MHI). The time taken to assign each was recorded. RESULTS: Participants showed good inter-rater consistency (ICC 0.83, 95 % CI 0.626, 0.976) and agreement (ICC 0.815, 95 % CI 0.602, 0.974) for assigned POEM scores. Expert scoring of videos correlated with offline values for PVD (R 2 = 0.39; p < 0.05), PPV (R 2 = 0.71; p < 0.001), MFI (R 2 = 0.75; p < 0.001), and MHI (R 2 = 0.68; p < 0.001). POEM scores took less time to assign than conventional offline computer analysis (2 minutes versus 44 minutes). CONCLUSION: We present for the first time a novel 5 point ordinal scale of microcirculatory flow and heterogeneity that can be used at the point of care. It has minimal inter-user variability amongst healthcare professionals after just 1 hour of training. POEM scores take a short time to assign, and correspond well to traditional offline computer-analyzed parameters. PMID- 27716374 TI - Prevalence of Angiostrongylus vasorum in southern Belgium, a coprological and serological survey. AB - BACKGROUND: Canine angiostrongylosis, a gastropod-borne helminthic infection, is increasingly being described in North America and is now reported in many European countries. In dogs, Angiostrongylus vasorum may cause a wide spectrum of clinical signs. Respiratory distress such as coughing and dyspnoea are the most frequently described manifestations. The aim of the present study was to gain additional information on the distribution, prevalence and risk factors associated with A. vasorum infection in dog from southern Belgium through the combined used of a commercially available in-clinic assay for detection of circulating antigen (Angio DetectTM, IDEXX, Westbrook, USA) and coprology in two different canine populations: dogs with clinical signs compatible with angiostrongylosis and asymptomatic dogs or dogs presented for unrelated conditions (control). RESULTS: A total of 979 dogs were enrolled in the study from November 2014 until February 2016. Seven hundred fifty-seven dogs were included in the control group, whereas 222 dogs had clinical signs compatible with angiostrongylosis. Forty-six dogs out of 979 (4.7 %) had A. vasorum circulating antigen. There was a highly significant difference between the two populations (3.6 % (27/747) and 8.6 % (19/222) in control and symptomatic dogs, respectively) (P = 0.00379). First stage larvae (L1) of A. vasorum were found in seven out of 24 serologically positive control dogs and in six out of 17 serologically positive symptomatic dogs. Interestingly, L1 of Crenosoma vulpis were detected by Baermann technique in one control and nine symptomatic dogs, respectively. Out of 17 Angio DetectTM (IDEXX, Westbrook, USA) positive dogs with negative (14) or not performed Baermann test (three), one dog was positive in both in-house ELISAs (Ag and Ab) and one dog was positive for Ag. Statistical analysis was unable to detect any risk factors associated with the direct and/or indirect detection of A. vasorum. CONCLUSIONS: This seroepidemiological study demonstrated for the first time a high seroprevalence in Southern Belgium for A. vasorum. The Angio DetectTM was found to be suitable in this context as the collection, preservation and examination of stools were difficult. Nevertheless, discrepancies were observed between the different available tests. Additional research is clearly needed. Also, coproscopy remains a very useful tool in dogs infected for less than nine weeks and for the identification of other canine lung nematodes such as C. vulpis. This study also demonstrates that asymptomatic dogs may shed A. vasorum L1 in their faeces and therefore contribute to the maintenance of A. vasorum life-cycle. PMID- 27716375 TI - Erratum to: A benchmark for RNA-seq quantification pipelines. PMID- 27716376 TI - Lipiodol retention pattern assessed by cone beam computed tomography during conventional transarterial chemoembolization of hepatocellular carcinoma: accuracy and correlation with response. AB - BACKGROUND: To investigate accuracy of intraprocedural cone beam computed tomography (CBCT) compared to fluoroscopy for detection of lipiodol retention pattern during conventional transarterial chemoembolization (cTACE) of hepatocellular carcinoma (HCC) and its correlation with short-term response. METHODS: Between September 2013 and July 2014, 29 patients with HCC underwent chemoembolization of 51 tumors (mean diameter 28.1 mm, range 10.0-136.3 mm). Lipiodol retention pattern was assessed by CBCT at the endpoint of cTACE compared by fluoroscopy. Depending on the pattern of tumor covered by lipiodol three classes were defined: complete (more than 90 %, no peripheral defects), moderate (50-90 %, some with or without peripheral defects), and poor (less than 50 %). Tumor response was assessed by modified Response Evaluation Criteria in Solid Tumors (mRECIST) based on follow-up contrast enhanced (CE) computed tomography (CT) or magnetic resonance imaging (MRI) obtained 4-6 weeks post-cTACE. Correlations between lipiodol retention patterns on CBCT and fluoroscopy as well as tumor response were assessed using multivariate logistic regression. RESULTS: Of 51 hepatic tumors, 40 (78.4 %) had complete response (CR); 8 (15.7 %) had partial response (PR); 1 (2.0 %) had stable disease (SD); and 2 (3.9 %) had progressive disease (PD). The degree of lipiodol retention scored excellent, moderate, and poor, in fluoroscopic images vs CBCT images were 23 (45.1 %) vs 39 (76.5 %), 19 (37.3 %) vs 11 (21.6 %), and 9 (17.6 %) vs 1 (2.0 %), respectively. Lipiodol retention assessment with CBCT (Az = 0.75) is more accurate than fluoroscopy (Az = 0.54) in predicting target tumor response. Other than lipiodol retention pattern assessed with CBCT (p = 0.01), tumor size (p = 0.04) is an independent predictors of CR. CONCLUSION: CBCT is more accurate than fluoroscopy in classification of lipiodol retention pattern in HCC tumors at the time of cTACE. CBCT could be used as a reliable intra precedural monitoring modality of cTACE. PMID- 27716378 TI - Assessment of clinical trial participant patient satisfaction: a call to action. AB - BACKGROUND: As patient satisfaction scores become increasingly relevant in today's health care market, we sought to evaluate satisfaction of the unique subset of patients enrolling in clinical trials in a research facility embedded within a community hospital system. METHODS: We developed and deployed a patient satisfaction survey tailored to clinical trial patients who consented to and/or completed a clinical trial in our research institute in the prior year. The survey was distributed to 222 patients. Likert scale responses were analyzed using top box and percentile rank procedures. Correlation analysis was used to evaluate associations between the clinical trial experience and intent to return to our system for routine care. RESULTS: Ninety surveys were returned in the 6 months following the mailing for a 41 % response rate; the bulk of these (N = 81) were returned within 6 weeks of the mailing. The questions with the highest ranking responses were related to interactions with staff (84th percentile or higher). Fifty-one point one percent of patients (64th percentile) strongly agreed that they would seek future care in our system. Patient intent to return to the provider seen during the clinical trial was most highly correlated with intent to seek future care within our system (r = 0.54, p < 0.0001). Reasons cited for clinical trial enrollment were generally altruistic. CONCLUSIONS: Querying this special patient population is feasible and yields valuable insight into their experience with healthcare system-based clinical trials and the relationship between clinical trial participation and perception of the healthcare system as a desirable resource for routine medical care. We argue that this work is invaluable to the research community and submit a call to action to our peers to begin systematic evaluation of clinical trial patient satisfaction. PMID- 27716377 TI - Urine biomarkers give early prediction of acute kidney injury and outcome after out-of-hospital cardiac arrest. AB - BACKGROUND: Post-resuscitation care after out-of-hospital cardiac arrest (OHCA) is challenging due to the threat of organ failure and difficult prognostication. Our aim was to examine whether urine biomarkers could give an early prediction of acute kidney injury (AKI) and outcome. METHODS: This was a prospective observational study of comatose OHCA patients at Oslo University Hospital Ulleval, Norway. Risk factors were clinical parameters and biomarkers measured in spot urine (cystatin C, neutrophil gelatinase-associated lipocalin (NGAL) and the product of tissue inhibitor of metalloproteinase 2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7)) at admission and day 3. Outcome variables were AKI within 3 days using the Kidney Disease Improving Global Outcomes definition, 6-month mortality, and poor neurological outcome (PNO) defined as cerebral performance category 3-5. RESULTS: Among 195 included patients (85 % males, mean age 60 years), 88 (45 %) died, 96 (49 %) had PNO, and 88 (45 %) developed AKI. In univariate analysis, increased urine cystatin C and NGAL concentration sampled at admission and day 3 were independent risk factors for AKI, mortality and PNO. Increased urine TIMP-2 * IGFBP7 levels was associated with AKI only at admission. In multivariate analyses combining clinical parameters and biomarker concentrations, the area under the receiver operating characteristics curve (AuROC) with 95 % confidence interval (CI) were 0.774 (0.700-0.848), 0.812 (0.751-0.873), and 0.819 (0.759-0.878) for AKI, mortality and PNO, respectively. CONCLUSIONS: In comatose OHCA patients, urine levels of cystatin C and NGAL at admission and day 3 were independent risk factors for AKI, 6-month mortality and PNO.

AB - This paper challenges the current management of acute traumatic spinal cord injury based on our experience with monitoring from the injury site in the neurointensive care unit. We argue that the concept of bony decompression is inadequate. The concept of optimum spinal cord perfusion pressure, which differs between patients, is introduced. Such variability suggests individualized patient treatment. Failing to optimize spinal cord perfusion limits the entry of systemically administered drugs into the injured cord. We conclude that monitoring from the injury site helps optimize management and should be subjected to a trial to determine whether it improves outcome. PMID- 27716380 TI - A novel DNA/histone H4 peptide complex detects autoantibodies in systemic lupus erythematosus sera. AB - BACKGROUND: The detection of anti-dsDNA antibodies is critical for the diagnosis and follow-up of systemic lupus erythematosus (SLE) patients. The presently available assays are characterized by a non-optimal specificity (solid phase assays) or sensitivity (Crithidia Luciliae immunofluorescence test (CLIFT)). To overcome the limits of CLIFT and solid phase chromatin assays, we explored the diagnostic potential of an assay based on plasmid DNA containing a highly bent fragment of 211 bp from Crithidia Luciliae minicircles, complexed with histone peptides. METHODS: Electrically neutral complexes of PK201/CAT plasmid (PK) DNA and histone 4 (H4) peptides were evaluated by electromobility shift assay. Complexes of H4 peptides and PK were absorbed to the solid phase to detect specific immunoglobulin G (IgG) in sera. Sera from 109 SLE patients, 100 normal healthy subjects, and 169 disease controls were tested. RESULTS: H4(14-34) containing the consensus sequence for DNA binding interacts with PK, retarding its migration. H4(14-34)/PK complexes were used to test sera by ELISA. Anti-H4-PK antibodies were detected in 56 % of SLE sera (more frequently in patients with skin or joint involvement) versus 5.9 % in disease controls; inhibition assays show that sera react with epitopes present on DNA or on the complex, not on the peptide. Antibody titer is correlated with European Consensus Lupus Activity Measurement (ECLAM) score and anti-complement component 1q (C1q) antibodies, negatively with C3 levels. Anti-H4-PK antibodies compared with CLIFT and solid phase dsDNA assays display moderate concordance. CONCLUSIONS: The H4/PK assay is a simple and reliable test which is useful for the differential diagnosis and evaluation of disease activity in SLE patients. PMID- 27716381 TI - Improving outcomes for hospital patients with critical bleeding requiring massive transfusion: the Australian and New Zealand Massive Transfusion Registry study methodology. AB - BACKGROUND: The Australian and New Zealand (ANZ) Massive Transfusion (MT) Registry (MTR) has been established to improve the quality of care of patients with critical bleeding (CB) requiring MT (>= 5 units red blood cells (RBC) over 4 h). The MTR is providing data to: (1) improve the evidence base for transfusion practice by systematically collecting data on transfusion practice and clinical outcomes; (2) monitor variations in practice and provide an opportunity for benchmarking, and feedback on practice/blood product use; (3) inform blood supply planning, inventory management and development of future clinical trials; and (4) measure and enhance translation of evidence into policy and patient blood management guidelines. The MTR commenced in 2011. At each participating site, all eligible patients aged >=18 years with CB from any clinical context receiving MT are included using a waived consent model. Patient information and clinical coding, transfusion history, and laboratory test results are extracted for each patient's hospital admission at the episode level. RESULTS: Thirty-two hospitals have enrolled and 3566 MT patients have been identified across Australia and New Zealand between 2011 and 2015. The majority of CB contexts are surgical, followed by trauma and gastrointestinal haemorrhage. Validation studies have verified that the definition of MT used in the registry correctly identifies 94 % of CB events, and that the median time of transfusion for the majority of fresh products is the 'product event issue time' from the hospital blood bank plus 20 min. Data linkage between the MTR and mortality databases in Australia and New Zealand will allow comparisons of risk-adjusted mortality estimates across different bleeding contexts, and between countries. Data extracts will be examined to determine if there are differences in patient outcomes according to transfusion practice. The ratios of blood components (e.g. FFP:RBC) used in different types of critical bleeding will also be investigated. CONCLUSIONS: The MTR is generating data with the potential to have an impact on management and policy decision-making in CB and MT and provide benchmarking and monitoring tools for immediate application. PMID- 27716382 TI - Gender differences in outcomes following isolated coronary artery bypass grafting: long-term results. AB - BACKGROUND: The main purpose of this study was to evaluate the impact of gender on outcomes after isolated coronary artery bypass grafting, in terms of 5-year rates of overall death, cardiac-related death, myocardial infarction, re hospitalization, repeat percutaneous or surgical revascularization, stroke, new pacemaker implantation, postoperative renal failure, heart failure and need for long-term care. METHODS: Two propensity-score matched cohorts, each of 1331 patients, undergoing isolated surgical coronary revascularization at the regional public and private centers of Emilia-Romagna region (Italy) from January 1st 2003 to December 31th 2013, were used to compare long-term outcomes of male (5976 patients) versus female gender (1332 patients). RESULTS: In the matched cohort, males received significantly more bypass grafts (3.0 +/- 1.0 vs 2.8 +/- 1.0, p = 0.001). Left internal mammary artery use and total arterial revascularization were similarly performed in both matched subgroups. Both groups reported similar cumulative rate of all-cause, cardiac-related mortality and stroke at five years. Females experienced significantly higher rate of myocardial infarction, and not significantly higher occurrence of heart failure, and need for long-term care. Males experienced significantly higher rate of cumulative re-hospitalization and higher need for pacemaker implantation. Female gender was not an independent predictor of death at long-term follow-up. CONCLUSIONS: Women are more likely to be readmitted with myocardial infarction and congestive heart failure after CABG but experience survival similar to that observed in men. Female gender was not an independent risk factor for mortality. Prevention of new occurrence of postoperative myocardial infarction and enhancement of complete coronary revascularization should be future endpoints. PMID- 27716383 TI - Upregulation of neuronal zinc finger protein A20 expression is required for electroacupuncture to attenuate the cerebral inflammatory injury mediated by the nuclear factor-kB signaling pathway in cerebral ischemia/reperfusion rats. AB - BACKGROUND: Zinc finger protein A20 (tumor necrosis factor alpha-induced protein 3) functions as a potent negative feedback inhibitor of the nuclear factor-kB (NF kB) signaling. It exerts these effects by interrupting the activation of IkB kinase beta (IKKbeta), the most critical kinase in upstream of NF-kB, and thereby controlling inflammatory homeostasis. We reported previously that electroacupuncture (EA) could effectively suppress IKKbeta activation. However, the mechanism underlying these effects was unclear. Therefore, the current study further explored the effects of EA on A20 expression in rat brain and investigated the possible mechanism of A20 in anti-neuroinflammation mediated by EA using transient middle cerebral artery occlusion (MCAO) rats. METHODS: Rats were treated with EA at the "Baihui (GV20)," "Hegu (L14)," and "Taichong (Liv3)" acupoints once a day starting 2 h after focal cerebral ischemia. The spatiotemporal expression of A20, neurobehavioral scores, infarction volumes, cytokine levels, glial cell activation, and the NF-kB signaling were assessed at the indicated time points. A20 gene interference (overexpression and silencing) was used to investigate the role of A20 in mediating the neuroprotective effects of EA and in regulating the interaction between neuronal and glial cells by suppressing neuronal NF-kB signaling during cerebral ischemia/reperfusion-induced neuroinflammation. RESULTS: EA treatment increased A20 expression with an earlier peak and longer lasting upregulation. The upregulated A20 protein was predominantly located in neurons in the cortical zone of the ischemia/reperfusion. Furthermore, neuronal A20 cell counts were positively correlated with neurobehavioral scores but negatively correlated with infarct volume, the accumulation of pro-inflammatory cytokines, and glial cell activation. Moreover, the effects of EA on improving the neurological outcome and suppressing neuroinflammation in the brain were reversed by A20 silencing. Finally, A20 silencing also suppressed the ability of EA to inhibit neuronal NF kB signaling pathway. CONCLUSIONS: Ischemia/reperfusion cortical neurons in MCAO rats are the main cell types that express A20, and there is a correlation between A20 expression and the suppression of neuroinflammation and the resulting neuroprotective effects. EA upregulated neuronal A20 expression, which played an essential role in the anti-inflammatory effects of EA by suppressing the neuronal NF-kB signaling pathway in the brains of MCAO rats. PMID- 27716385 TI - Complete nucleotide sequence of strawberry vein banding virus Chinese isolate and infectivity of its full-length DNA clone. AB - BACKGROUND: Strawberry vein banding virus (SVBV) is a double-stranded DNA plant virus, which has been found in North America, Australia, Brazil, Japan, Europe and several provinces of China. Infected strawberry plants exhibit mild vein banding symptoms and chlorosis along the veins. It is one of the most economically important diseases in Asiatic, European and North American strawberry-growing areas. FINDINGS: The complete genome of an SVBV Chinese isolate (SVBV-CN) was isolated and cloned from a naturally infected strawberry (Fragaria * ananassa cv. Sachinoka) sample found in Shenyang city of Liaoning province. Sequence analysis revealed a complete genome of 7864 nucleotides (nts) that indicated SVBV-CN was most closely related to SVBV from the United States (SVBV-US) with a sequence similarity of 85.8 %. Two major clades were identified based on phylogenetic analysis of the complete genome sequences of caulimoviruses. SVBV-CN clustered together with SVBV-US, whereas other caulimoviruses formed a separate branch. Agrobacterium-mediated inoculation of Fragaria vesca with an infectious clone of SVBV-CN results in systemic infection with distinct symptoms of yellowing bands along the main leaf veins. This suggests that the SVBV-CN infectious clone can recapitulate the symptoms observed in naturally infected strawberries, and therefore is likely the causal agent of the original disease observed in strawberries. Furthermore, strawberry plants inoculated with the infectious clone using vacuum infiltration developed symptoms with a very high infection rate of 86-100 % in 4-5 weeks post-inoculation. This compares to an infection rate of 20-40 % in 8-9 weeks post-inoculation using syringe-inoculation. CONCLUSIONS: The complete nucleotide sequence of SVBV from a naturally infected strawberry was determined. Agroinfiltration of strawberry plants using an infectious clone of SVBV-CN resulted in symptoms typically found in infected strawberries from Shenyang city of Liaoning province in China. This is the first report describing an infectious clone of SVBV-CN, and that vacuum infiltration can be potentially used as a new and highly efficient means for inoculation of strawberry plants. PMID- 27716386 TI - The production and sales of anti-tuberculosis drugs in China. AB - BACKGROUND: Tuberculosis (TB) is a major infectious disease globally. Adequate and proper use of anti-TB drugs is essential for TB control. This study aims to study China's production capacity and sales situation of anti-TB drugs, and to further discuss the potential for China to contribute to global TB control. METHODS: The production data of anti-TB drugs in China from 2011 to 2013 and the sales data from 2010 to 2014 were extracted from Ministry of Industry and Information Technology database of China and IMS Health database, respectively. The number of drugs was standardized to the molecular level of the key components before calculating. All data were described and analyzed by Microsoft Excel. RESULTS: First-line drugs were the majority in both sales (89.5 %) and production (92.3 %) of anti-TB drugs in China. The production of rifampicin held the majority share in active pharmaceutical ingredients (APIs) and finished products, whilst ethambutol and pyrazinamide were the top two sales in finished products. Fixed-dose combinations only held small percentages in total production and sales weight, though a slight increase was observed. The production and sales of streptomycin showed a tendency of decrease after 2012. The trends and proportion of different anti-TB drugs were similar in production and sales, however, the production weight was much larger than that of sales, especially for rifampicin and isoniazid. CONCLUSIONS: First-line drugs were the predominant medicine produced and used in China. While the low production and sales of the second-line TB drugs and FDCs rose concerns for the treatment of multiple drug resistant TB. The redundant production amount, as well as the prompt influence of national policy on drug production and sales, indicated the potential for China to better contribute to global TB control. PMID- 27716384 TI - Ion channels expression and function are strongly modified in solid tumors and vascular malformations. AB - BACKGROUND: Several cellular functions relate to ion-channels activity. Physiologically relevant chains of events leading to angiogenesis, cell cycle and different forms of cell death, require transmembrane voltage control. We hypothesized that the unordered angiogenesis occurring in solid cancers and vascular malformations might associate, at least in part, to ion-transport alteration. METHODS: The expression level of several ion-channels was analyzed in human solid tumor biopsies. Expression of 90 genes coding for ion-channels related proteins was investigated within the Oncomine database, in 25 independent patients-datasets referring to five histologically-different solid tumors (namely, bladder cancer, glioblastoma, melanoma, breast invasive-ductal cancer, lung carcinoma), in a total of 3673 patients (674 control-samples and 2999 cancer samples). Furthermore, the ion-channel activity was directly assessed by measuring in vivo the electrical sympathetic skin responses (SSR) on the skin of 14 patients affected by the flat port-wine stains vascular malformation, i.e., a non-tumor vascular malformation clinical model. RESULTS: Several ion-channels showed significantly increased expression in tumors (p < 0.0005); nine genes (namely, CACNA1D, FXYD3, FXYD5, HTR3A, KCNE3, KCNE4, KCNN4, CLIC1, TRPM3) showed such significant modification in at least half of datasets investigated for each cancer type. Moreover, in vivo analyses in flat port-wine stains patients showed a significantly reduced SSR in the affected skin as compared to the contralateral healthy skin (p < 0.05), in both latency and amplitude measurements. CONCLUSIONS: All together these data identify ion-channel genes showing significantly modified expression in different tumors and cancer-vessels, and indicate a relevant electrophysiological alteration in human vascular malformations. Such data suggest a possible role and a potential diagnostic application of the ion electron transport in vascular disorders underlying tumor neo-angiogenesis and vascular malformations. PMID- 27716387 TI - Extreme hypernatremia as a probable cause of fatal arrhythmia: a case report. AB - BACKGROUND: Hypernatremia is a frequent occurrence among hospitalized patients. Severe hypernatremia is associated with mortality rates of over 60 %. Extreme hypernatremia, defined as sodium levels >190 mmol/l, is a rare occurrence. The literature on electrocardiographic changes occurring with this degree of hypernatremia is extremely scarce. We report the case of an 11-year-old Sri Lankan girl who presented with sodium levels of 226 mmol/l following infusion with 3 % hypertonic saline who developed diffuse QT prolongation leading to fatal ventricular tachycardia. CASE PRESENTATION: An 11-year-old Sri Lankan girl presented with fever, headache, vomiting, and altered level of consciousness. Following admission she developed generalized tonic-clonic seizures and was intubated and ventilated. She had a recent history of polyuria and polydipsia. Magnetic resonance imaging of her brain revealed hydrocephalus due to possible craniopharyngioma. A ventriculoperitoneal shunt was inserted and she was infused with 3 % hypertonic saline in an attempt to reduce intracranial pressure. The following day she became polyuric and dehydrated with tachycardia and low blood pressure. Biochemistry revealed serum sodium of 226 mmol/l, measured serum osmolality of 470 mOsm/kg, urine osmolality of 280 mOsm/kg, urine spot sodium of 116 mmol/l, blood urea of 8.1 mmol/l, and blood glucose of 8.5 mmol/l. Her serum potassium, calcium, and magnesium levels were normal. Extreme hypernatremia due to infusion of 3 % hypertonic saline in the background of cranial diabetes insipidus was considered. She was managed aggressively with 5 % dextrose infusion and clear water via nasogastric feeding to correct the fluid deficit of 7 liters over 36 hours. Her sodium levels dropped to 160 mmol/l the following day. However, she developed electrocardiographic changes with widespread gross QT prolongation with ST segment deviations followed by fatal ventricular tachycardia. CONCLUSIONS: Extreme hypernatremia is rare, and the literature on electrocardiographic changes occurring at such high levels of sodium is scarce. At present there are no established guidelines on rate and mode of correction of such high sodium levels. This case highlights the electrocardiographic changes observed during extreme hypernatremia, controversies in managing increased intracranial pressure with hypertonic saline, and dilemmas encountered in managing extreme hypernatremia. PMID- 27716388 TI - The genetics of breast cancer risk in the post-genome era: thoughts on study design to move past BRCA and towards clinical relevance. AB - More than 12 % of women will be diagnosed with breast cancer in their lifetime. Although there have been tremendous advances in elucidating genetic risk factors underlying both familial and sporadic breast cancer, much of the genetic contribution to breast cancer etiology remains unknown. The discovery of BRCA1 and BRCA2 over 20 years ago remains the seminal event in the field and has paved the way for the discovery of other high-penetrance susceptibility genes by linkage analysis. The advent of genome-wide association studies made possible the next wave of discoveries, in which over 80 low-penetrance and moderate-penetrance variants were identified. Although these studies were highly successful at discovering variants associated with both familial and sporadic breast cancer, the variants identified to date explain only 50 % of the heritability of breast cancer. In this review, we look back at the investigative strategies that have led to our current understanding of breast cancer genetics, consider the challenges of performing association studies in heterogeneous complex diseases such as breast cancer, and look ahead toward the types of study designs that may lead to the identification of the genetic variation accounting for the remaining missing heritability. PMID- 27716389 TI - Recurrent patent infections with Toxocara canis in household dogs older than six months: a prospective study. AB - BACKGROUND: To reduce environmental contamination with Toxocara canis eggs, the current general advice is to deworm all dogs older than six months on average four times a year. However, only a small proportion of non-juvenile household dogs actually shed T. canis eggs, and some dogs shed eggs more frequently than others. The identification of these frequent shedders and the associated risk factors is an important cornerstone for constructing evidence-based deworming regimens. The purpose of this study is to identify risk factors associated with recurrence of periods of shedding Toxocara eggs in a cohort of household dogs older than six months. METHODS: We performed a prospective study (July 2011 to October 2014) on shedding Toxocara eggs in a cohort of 938 household dogs older than six months from all over the Netherlands. The median follow-up time was 14 months. Monthly, owners sent faecal samples of their dogs for Toxocara testing and completed a questionnaire. Dogs were dewormed only after diagnosis of a patent infection (PI). Survival analysis was used to assess factors influencing the time to first diagnosed PIs (FPI) and the time to recurrent PIs (RPI). RESULTS: The overall prevalence of PIs was 4.5 %, resulting in an estimated average incidence of 0.54 PIs/dog/year. No PI was diagnosed in 67.9 % of the dogs, 17.5 % of the dogs went through only one PI and 14.6 % had > 1 PI. Prevalence of PIs always peaked during wintertime. Increased hazards for first diagnosed PIs were associated with coprophagy, geophagy, walking off-leash for >= 80 % of walking time, reported worms in the faeces, feeding a commercial diet and suffering from urologic or respiratory conditions. Median time to reinfection was nine months. Factors associated with increased hazards for recurrent PIs were taking corticosteroids, changing dog's main purpose, and proxies for veterinary care-seeking behaviours. CONCLUSIONS: We concluded that targeted anthelmintic treatments in household dogs may be feasible as PIs tend to (re)occur in specific periods and in groups of dogs at high risk. Moreover, recurrent PIs appear to be influenced more by factors related to impaired immunity than environmental exposure to Toxocara eggs. PMID- 27716390 TI - The organisation of physiotherapy for people with multiple sclerosis across Europe: a multicentre questionnaire survey. AB - BACKGROUND: Understanding the organisational set-up of physiotherapy services across different countries is increasingly important as clinicians around the world use evidence to improve their practice. This also has to be taken into consideration when multi-centre international clinical trials are conducted. This survey aimed to systematically describe organisational aspects of physiotherapy services for people with multiple sclerosis (MS) across Europe. METHODS: Representatives from 72 rehabilitation facilities within 23 European countries completed an online web-based questionnaire survey between 2013 and 2014. Countries were categorised according to four European regions (defined by United Nations Statistics). Similarities and differences between regions were examined. RESULTS: Most participating centres specialized in rehabilitation (82 %) and neurology (60 %), with only 38 % specialising in MS. Of these, the Western based Specialist MS centres were predominately based on outpatient services (median MS inpatient ratio 0.14), whilst the Eastern based European services were mostly inpatient in nature (median MS inpatient ratio 0.5). In almost all participating countries, medical doctors - specialists in neurology (60 %) and in rehabilitation (64 %) - were responsible for referral to/prescription of physiotherapy. The most frequent reason for referral to/prescription of physiotherapy was the worsening of symptoms (78 % of centres). Physiotherapists were the most common members of the rehabilitation team; comprising 49 % of the team in Eastern countries compared to approximately 30 % in the rest of Europe. Teamwork was commonly adopted; 86 % of centres based in Western countries utilised the interdisciplinary model, whilst the multidisciplinary model was utilised in Eastern based countries (p = 0.046). CONCLUSION: This survey is the first to provide data about organisational aspects of physiotherapy for people with MS across Europe. Overall, care in key organisational aspects of service provision is broadly similar across regions, although some variations, for example the models of teamwork utilised, are apparent. Organisational framework specifics should be considered anytime a multi-centre study is conducted and results from such studies are applied. PMID- 27716391 TI - Toll-like receptor 2 (TLR2) plays a role in controlling cutaneous leishmaniasis in vivo, but does not require activation by parasite lipophosphoglycan. AB - BACKGROUND: Leishmaniasis is a neglected tropical disease affecting millions of individuals worldwide. Despite several studies reporting involvement of the innate immune receptor Toll-like receptor 2 (TLR2) in the recognition of surface glycolipids from Leishmania parasites in vitro, the role of TLR2 and its co receptors during cutaneous leishmaniasis infection in vivo is unknown. METHODS: To explore the role of TLR2 and its co-receptors in cutaneous leishmaniasis, mice deficient in either TLR2, 4, 1 or 6, or wild-type (WT) controls, were infected with either Leishmania major promastigotes, L. mexicana promastigotes, L. mexicana amastigotes, or LPG1 -/- L. mexicana promastigotes. For each infection, lesion sizes were monitored and parasite burden was assessed at various time points. To assess immune responses, draining lymph node (DLN) cells were re stimulated with parasite antigens and the production of cytokines and parasite specific antibody isotypes in blood was determined by ELISA. RESULTS: Mice deficient in TLR2 and TLR4 presented with larger lesions and higher parasite burdens than WT controls. Mice lacking TLR2 co-receptors TLR1 or TLR6 did not show exacerbated infection, suggesting that TLR2 does not require either co receptor in the recognition of Leishmania infection. Furthermore, it appears that lipophosphoglycan (LPG) is not the major mediator of TLR2 activation during infection with L. mexicana, as parasites lacking LPG (axenic amastigotes and LPG1 -/- promastigotes) also resulted in exacerbated disease in TLR2-/- mice. Infected TLR2-/- mice show a skewed Th2 immune response to Leishmania parasites, as demonstrated by elevated IL-4, IL-13 and IL-10 production by DLN cells from L. mexicana infected mice in response to antigen. Furthermore, L. major infected TLR2-/- mice have elevated antigen-specific IgG1 antibodies. CONCLUSIONS: TLR2 deficiency leads to exacerbation of disease and parasite burden through promotion of Th2 immunity. TLR2 activation in vivo occurs independently of parasite LPG, suggesting other parasite ligands are involved in TLR2 recognition of Leishmania. PMID- 27716392 TI - Genetic variability and spatial distribution in small geographic scale of Aedes aegypti (Diptera: Culicidae) under different climatic conditions in Northeastern Brazil. AB - BACKGROUND: The study of the genetic structure of Aedes aegypti is essential to understanding their population dynamics as well as for the analysis of factors responsible for their resistance and ecological adaptation. The use of molecular markers in identifying differences amongst populations of Ae. aegypti in different geographical areas as well as the temporal variation of the vector populations has contributed to the improvement of vector control strategies. The present study aims to determine the genetic variability of Ae. aegypti populations in a small geographical area (state of Sergipe, Northeastern Brazil) by means of inter-simple sequence repeat (ISSR) and single nucleotide polymorphism (SNP) molecular markers. RESULTS: ISSR markers revealed a more heterogeneous pattern of genetic diversity among the populations with an expected heterozygosity (H E) ranging from 0.261 +/- 0.03 to 0.120 +/- 0.032, while a similar trend was detected through SNPs across populations with an H E between 0.375 +/- 0.054 and 0.269 +/- 0.042. The population's genetic differentiation assessed with ISSR and SNP markers indicated a very low structuring among the populations with the highest diversity observed within the populations 72 % (ISSR) and 92 % (SNP). Clustering analysis also suggested little variation among populations: the seven populations were grouped into only three ISSR clusters and a single panmictic group based on SNP markers. The present study identified a close relationship between the populations, which probably results mainly from passive gene flow between mosquitoes from distinct geographic regions, influenced by humans commuting along roads. CONCLUSIONS: There was an intense migration of mosquitos across municipalities, leading to a potential increase in risk of arbovirus and insecticide resistance associated-alleles spreading between mosquito populations. PMID- 27716394 TI - Germline, hematopoietic, mosaic, and somatic variation: interplay between inherited and acquired genetic alterations in disease assessment. AB - Advances in genetic analysis have revealed new complexities in the interpretation of genetic variants. Correct assessment of a genetic variant relies on the clinical context and knowledge of the underlying biology. We outline four scenarios encountered in genetic testing where careful consideration of the origin of genetic variation is required for variant interpretation. PMID- 27716393 TI - Topological analysis of metabolic networks integrating co-segregating transcriptomes and metabolomes in type 2 diabetic rat congenic series. AB - BACKGROUND: The genetic regulation of metabolic phenotypes (i.e., metabotypes) in type 2 diabetes mellitus occurs through complex organ-specific cellular mechanisms and networks contributing to impaired insulin secretion and insulin resistance. Genome-wide gene expression profiling systems can dissect the genetic contributions to metabolome and transcriptome regulations. The integrative analysis of multiple gene expression traits and metabolic phenotypes (i.e., metabotypes) together with their underlying genetic regulation remains a challenge. Here, we introduce a systems genetics approach based on the topological analysis of a combined molecular network made of genes and metabolites identified through expression and metabotype quantitative trait locus mapping (i.e., eQTL and mQTL) to prioritise biological characterisation of candidate genes and traits. METHODS: We used systematic metabotyping by 1H NMR spectroscopy and genome-wide gene expression in white adipose tissue to map molecular phenotypes to genomic blocks associated with obesity and insulin secretion in a series of rat congenic strains derived from spontaneously diabetic Goto-Kakizaki (GK) and normoglycemic Brown-Norway (BN) rats. We implemented a network biology strategy approach to visualize the shortest paths between metabolites and genes significantly associated with each genomic block. RESULTS: Despite strong genomic similarities (95-99 %) among congenics, each strain exhibited specific patterns of gene expression and metabotypes, reflecting the metabolic consequences of series of linked genetic polymorphisms in the congenic intervals. We subsequently used the congenic panel to map quantitative trait loci underlying specific mQTLs and genome-wide eQTLs. Variation in key metabolites like glucose, succinate, lactate, or 3-hydroxybutyrate and second messenger precursors like inositol was associated with several independent genomic intervals, indicating functional redundancy in these regions. To navigate through the complexity of these association networks we mapped candidate genes and metabolites onto metabolic pathways and implemented a shortest path strategy to highlight potential mechanistic links between metabolites and transcripts at colocalized mQTLs and eQTLs. Minimizing the shortest path length drove prioritization of biological validations by gene silencing. CONCLUSIONS: These results underline the importance of network-based integration of multilevel systems genetics datasets to improve understanding of the genetic architecture of metabotype and transcriptomic regulation and to characterize novel functional roles for genes determining tissue-specific metabolism. PMID- 27716395 TI - Thymosin beta4 and beta10 in Sjogren's syndrome: saliva proteomics and minor salivary glands expression. AB - BACKGROUND: In the present study, we investigated whether thymosin beta (Tbeta) in saliva and in minor salivary glands is differentially expressed in patients with primary Sjogren's syndrome (pSS) and patients with autoimmune diseases (systemic sclerosis [SSc], systemic lupus erythematosus [SLE], and rheumatoid arthritis [RA], with and without sicca syndrome [ss]). METHODS: Saliva specimens of nine patients with pSS, seven with ss/SSc, seven with ss/SLE, seven with ss/RA, seven with SSc, seven with SLE, and seven with RA, as well as ten healthy subjects, were analyzed using a high-performance liquid chromatograph coupled with a mass spectrometer equipped with an electrospray ionization source to investigate the presence and levels of Tbeta4, Tbeta4 sulfoxide, and Tbeta10. Immunostaining for Tbeta4 and Tbeta10 was performed on minor salivary glands of patients with pSS and ss. RESULTS: Tbeta4 levels were statistically higher in patients with pSS with respect to the other subgroups. Tbeta10 was detectable in 66.7 % of patients with pSS and in 42.8 % of those with ss/SSc, while Tbeta4 sulfoxide was detectable in 44.4 % of patients with pSS and in 42.9 % of those with ss/SSc. Tbeta10 and Tbeta4 sulfoxide were not detectable in patients without associated ss and in healthy control subjects. Regarding thymosin immunostaining, all patients had immunoreactivity for Tbeta10, and a comparable distribution pattern in the four different subgroups of patients was observed. Tbeta4 immunoreactivity was present in patients with ss/SSc and those with ss/SLE, while it was completely absent in patients with pSS and those with ss/RA. CONCLUSIONS: Our data show that higher salivary Tbeta expression characterizes patients with pSS, while Tbeta4 sulfoxide and Tbeta10 salivary expression was selectively present in patients with sicca symptoms. Moreover, at the immunohistochemical level in patients with pSS, minor salivary glands showed a peculiar pattern characterized by immunostaining for Tbeta10 in acinar cells in the absence of any reactivity for Tbeta4. These findings, taken together, suggest a different role for Tbeta4 and Tbeta10 in patients with pSS who have ss and other autoimmune disease. PMID- 27716396 TI - Glucocorticoid-induced leucine zipper (GILZ) is involved in glucocorticoid induced and mineralocorticoid-induced leptin production by osteoarthritis synovial fibroblasts. AB - BACKGROUND: Glucocorticoid-induced leucine zipper (GILZ) is a mediator of the anti-inflammatory activities of glucocorticoids. However, GILZ deletion does not impair the anti-inflammatory activities of exogenous glucocorticoids in mice arthritis models and GILZ could also mediate some glucocorticoid-related adverse events. Osteoarthritis (OA) is a metabolic disorder that is partly attributed to adipokines such as leptin, and we previously observed that glucocorticoids induced leptin secretion in OA synovial fibroblasts. The purpose of this study was to position GILZ in OA through its involvement in the anti-inflammatory activities of glucocorticoids and/or in the metabolic pathway of leptin induction. The influences of mineralocorticoids on GILZ and leptin expression were also investigated. METHODS: Human synovial fibroblasts were isolated from OA patients during knee replacement surgery. Then, the cells were treated with a glucocorticoid (prednisolone), a mineralocorticoid (aldosterone), a glucocorticoid receptor (GR) antagonist (mifepristone), a selective glucocorticoid receptor agonist (Compound A), mineralocorticoid receptor (MR) antagonists (eplerenone and spironolactone), TNF-alpha or transforming growth factor (TGF)-beta. Cells were transfected with shRNA lentiviruses for the silencing of GILZ and GR. The leptin, IL-6, IL-8 and matrix metalloproteinase (MMP)-1 levels were measured by ELISA. Leptin, the leptin receptor (Ob-R), GR and GILZ expression levels were analyzed by western blotting and/or RT-qPCR. RESULTS: (1) The glucocorticoid prednisolone and the mineralocorticoid aldosterone induced GILZ expression dose-dependently in OA synovial fibroblasts, through GR but not MR. Similar effects on leptin and Ob-R were observed: leptin secretion and Ob-R expression were also induced by prednisolone and aldosterone through GR; (2) GILZ silencing experiments demonstrated that GILZ was involved in the glucocorticoid induced and mineralocorticoid-induced leptin secretion and Ob-R expression in OA synovial fibroblasts; and (3) GILZ inhibition did not alter the production of pro inflammatory cytokines by OA synovial fibroblast or the anti-inflammatory properties of glucocorticoids. CONCLUSIONS: The absence of GILZ prevents corticoid-induced leptin and Ob-R expression without affecting the anti inflammatory properties of glucocorticoids in OA synovial fibroblasts. Mineralocorticoids also induce leptin and Ob-R expression through GILZ. PMID- 27716397 TI - A20 suppresses canonical Smad-dependent fibroblast activation: novel function for an endogenous inflammatory modulator. AB - BACKGROUND: The ubiquitin-editing cytosolic enzyme A20, the major negative regulator of toll-like receptor (TLR)-mediated cellular inflammatory responses, has tight genetic linkage with systemic sclerosis (SSc). Because recent studies implicate endogenous ligand-driven TLR signaling in SSc pathogenesis, we sought to investigate the regulation, role and mechanism of action of A20 in skin fibroblasts. METHOD: A20 expression and the effects of forced A20 expression or siRNA-mediated A20 knockdown on fibrotic responses induced by transforming growth factor-beta (TGF-beta) were evaluated was evaluated in explanted human skin fibroblasts. Additionally, A20 regulation by TGF-beta, and by adiponectin, a pleiotropic adipokine with anti-fibrotic activity, was evaluated. RESULTS: In normal fibroblasts, TGF-beta induced sustained downregulation of A20, and abrogated its TLR4-dependent induction. Forced expression of A20 aborted the stimulation of collagen gene expression and myofibroblast transformation induced by TGF-beta, and disrupted canonical Smad signaling and Smad-dependent transcriptional responses. Conversely, siRNA-mediated knockdown of A20 enhanced the amplitude of fibrotic responses elicited by TGF-beta. Adiponectin, previously shown to block TLR-dependent fibrotic responses, elicited rapid and sustained increase in A20 accumulation in fibroblasts. CONCLUSION: These results identify the ubiquitin-editing enzyme A20 as a novel endogenous mechanism for negative regulation of fibrotic response intensity. Systemic sclerosis-associated genetic variants of A20 that cause impaired A20 expression or function, combined with direct suppression of A20 by TGF-beta within the fibrotic milieu, might play a significant functional role in persistence of fibrotic responses, while pharmacological augmentation of A20 inhibitory pathway activity might represent a novel therapeutic strategy. PMID- 27716398 TI - Challenges in and lessons learned during the implementation of the 1-3-7 malaria surveillance and response strategy in China: a qualitative study. AB - BACKGROUND: China has made great progress in malaria control over the last century and now aims to eliminate malaria by 2020. In 2012, the country launched its 1-3-7 surveillance and response strategy for malaria elimination. The strategy involves to case reporting within 1 day, case investigation within 3 days, and focus investigation and public health actions within 7 days. The aim of this study was to evaluate the challenges in and lessons learned during the implementation of the 1-3-7 strategy in China so far. METHODS: This qualitative study was conducted in two provinces in China: Gansu province (northwestern China) and Jiangsu province (southeastern China) in 2014. Key informant interviews (n = 6) and in-depth interviews (n = 36) about the implementation aspects of the 1-3-7 strategy were conducted with malaria experts, health staff, laboratory practitioners, and village doctors at the provincial, city, county, township, and village levels. RESULTS: Broad themes related to the challenges in and lessons learned during the implementation of the 1-3-7 strategy were identified according to: case reporting within 1 day, case investigation within 3 days, focus investigation within 7 days, and the overall strategy. The major challenges outlined were related to respecting the timeline of surveillance procedures, the absence of or difficulties in following guidelines on conducting focus investigations, diagnostics, and the increasing number of returning migrant workers from malaria-endemic countries. Important lessons learned revolve around the importance of continuous capacity building, supervision and motivation, quality control, information technology support, applied research, governmental commitment, and intersectoral collaboration. CONCLUSIONS: Surveillance is a key intervention in malaria elimination programs. The Chinese 1-3-7 strategy has already proven to be successful but still needs to be improved. In particular, dealing appropriately with imported malaria cases through the screening of migrant workers from malaria-endemic countries is essential for achieving and sustaining malaria elimination in China. China has perfect preconditions for successful malaria elimination provided political commitment and financial investment are guaranteed. The 1-3-7 strategy may also be considered as a model for other countries. PMID- 27716399 TI - Continuous evolution of clinical phenotype in 578 Japanese patients with Behcet's disease: a retrospective observational study. AB - BACKGROUND: It has been suggested that the phenotypes of Behcet's disease (BD) in Japan are changing. To ask whether the evolution of BD holds true in recent-onset cases in Japan, we performed a retrospective study. METHODS: We reviewed the records of 578 patients with BD who met the 1987 revised diagnostic criteria of the Behcet's disease research committee of Japan. The patients were divided into three groups based on the date of disease onset. We compared the demography, clinical features, and treatments among them with or without adjustment for the observation period. Patients having oral ulcers, genital ulcers, regional skin involvement, and uveitis are categorized as having complete-type BD, and the associated factors were determined by univariate and multivariate logistic regression analyses. RESULTS: Male patients had a higher propensity for uveitis and central nervous system (CNS) involvement, whereas female patients had higher rates of genital ulcers and arthritis. We found a significant trend in reduction of complete-type, genital ulcer, HLA-B51 carriers, and increment of gastrointestinal BD over time. Multiple regression analysis identified HLA-B51 positivity, earlier date of disease onset, and younger age of onset as independently associated with complete-type BD. Although treatments had been also chronologically changed, the causative relationship between therapeutic agents and phenotypical changes was not determined from the study. CONCLUSION: The present study revealed that phenotypical evolution was characterized by decreased incidence of the complete type and increment of gastrointestinal involvement in Japanese patients with BD during the last 30 years. PMID- 27716400 TI - PERK regulates Gq protein-coupled intracellular Ca2+ dynamics in primary cortical neurons. AB - PERK (EIF2AK3) is an ER-resident eIF2alpha kinase required for behavioral flexibility and metabotropic glutamate receptor-dependent long-term depression via its translational control. Motivated by the recent discoveries that PERK regulates Ca2+ dynamics in insulin-secreting beta-cells underlying glucose stimulated insulin secretion, and modulates Ca2+ signals-dependent working memory, we explored the role of PERK in regulating Gq protein-coupled Ca2+ dynamics in pyramidal neurons. We found that acute PERK inhibition by the use of a highly specific PERK inhibitor reduced the intracellular Ca2+ rise stimulated by the activation of acetylcholine, metabotropic glutamate and bradykinin-2 receptors in primary cortical neurons. More specifically, acute PERK inhibition increased IP3 receptor mediated ER Ca2+ release, but decreased receptor-operated extracellular Ca2+ influx. Impaired Gq protein-coupled intracellular Ca2+ rise was also observed in genetic Perk knockout neurons. Taken together, our findings reveal a novel role of PERK in neurons, which is eIF2alpha-independent, and suggest that the impaired working memory in forebrain-specific Perk knockout mice may stem from altered Gq protein-coupled intracellular Ca2+ dynamics in cortical pyramidal neurons. PMID- 27716401 TI - Altered gut microbiota in female mice with persistent low body weights following removal of post-weaning chronic dietary restriction. AB - BACKGROUND: Nutritional interventions often fail to prevent growth failure in childhood and adolescent malnutrition and the mechanisms remain unclear. Recent studies revealed altered microbiota in malnourished children and anorexia nervosa. To facilitate mechanistic studies under physiologically relevant conditions, we established a mouse model of growth failure following chronic dietary restriction and examined microbiota in relation to age, diet, body weight, and anabolic treatment. METHODS: Four-week-old female BALB/c mice (n = 12/group) were fed ad libitum (AL) or offered limited food to abolish weight gain (LF). A subset of restricted mice was treated with an insulin-like growth factor 1 (IGF1) analog. Food access was restored in a subset of untreated LF (LF-RF) and IGF1-treated LF mice (TLF-RF) on day 97. Gut microbiota were determined on days 69, 96-99 and 120 by next generation sequencing of the V3-5 region of the 16S rRNA gene. Microbiota-host factor associations were analyzed by distance-based PERMANOVA and quantified by the coefficient of determination R2 for age, diet, and normalized body weight change (Deltabwt). Microbial taxa on day 120 were compared following fitting with an overdispersed Poisson regression model. The machine learning algorithm Random Forests was used to predict age based on the microbiota. RESULTS: On day 120, Deltabwt in AL, LF, LF-RF, and TLF-RF mice was 52 +/- 3, -6 +/- 1*, 40 +/- 3*, and 46 +/- 2 % (*, P < 0.05 versus AL). Age and diet, but not Deltabwt, were associated with gut microbiota composition. Age explained a larger proportion of the microbiota variability than diet or Deltabwt. Random Forests predicted chronological age based on the microbiota and indicated microbiota immaturity in the LF mice before, but not after, refeeding. However, on day 120, the microbiota community structure of LF-RF mice was significantly different from that of both AL and LF mice. IGF1 mitigated the difference from the AL group. Refed groups had a higher abundance of Bacteroidetes and Proteobacteria and a lower abundance of Firmicutes than AL mice. CONCLUSIONS: Persistent growth failure can be induced by 97-day dietary restriction in young female mice and is associated with microbiota changes seen in lean mice and individuals and anorexia nervosa. IGF1 facilitates recovery of body weights and microbiota. PMID- 27716402 TI - Decatecholaminisation during sepsis. PMID- 27716403 TI - Lesinurad, a novel, oral compound for gout, acts to decrease serum uric acid through inhibition of urate transporters in the kidney. AB - BACKGROUND: Excess body burden of uric acid promotes gout. Diminished renal clearance of uric acid causes hyperuricemia in most patients with gout, and the renal urate transporter (URAT)1 is important for regulation of serum uric acid (sUA) levels. The URAT1 inhibitors probenecid and benzbromarone are used as gout therapies; however, their use is limited by drug-drug interactions and off-target toxicity, respectively. Here, we define the mechanism of action of lesinurad (Zurampic(r); RDEA594), a novel URAT1 inhibitor, recently approved in the USA and Europe for treatment of chronic gout. METHODS: sUA levels, fractional excretion of uric acid (FEUA), lesinurad plasma levels, and urinary excretion of lesinurad were measured in healthy volunteers treated with lesinurad. In addition, lesinurad, probenecid, and benzbromarone were compared in vitro for effects on urate transporters and the organic anion transporters (OAT)1 and OAT3, changes in mitochondrial membrane potential, and human peroxisome proliferator-activated receptor gamma (PPARgamma) activity. RESULTS: After 6 hours, a single 200-mg dose of lesinurad elevated FEUA 3.6-fold (p < 0.001) and reduced sUA levels by 33 % (p < 0.001). At concentrations achieved in the clinic, lesinurad inhibited activity of URAT1 and OAT4 in vitro, did not inhibit GLUT9, and had no effect on ABCG2. Lesinurad also showed a low risk for mitochondrial toxicity and PPARgamma induction compared to benzbromarone. Unlike probenecid, lesinurad did not inhibit OAT1 or OAT3 in the clinical setting. CONCLUSION: The pharmacodynamic effects and in vitro activity of lesinurad are consistent with inhibition of URAT1 and OAT4, major apical transporters for uric acid. Lesinurad also has a favorable selectivity and safety profile, consistent with an important role in sUA-lowering therapy for patients with gout. PMID- 27716405 TI - Noninvasive ventilation for avoidance of reintubation in patients with various cough strength. AB - BACKGROUND: Reintubation is associated with high mortality. Identification of methods to avoid reintubation is needed. The aim of this study was to assess whether prophylactic noninvasive ventilation (NIV) would benefit patients with various cough strengths. METHODS: We prospectively enrolled 356 patients who successfully passed a spontaneous breathing trial in a respiratory intensive care unit. Before extubation, cough peak flow was measured. After extubation, attending physicians determined whether the patients would receive prophylactic NIV or conventional oxygen treatment (control group). Patients were followed up to 90 days postextubation or death, whichever came first. RESULTS: The median value of cough peak flow was 70 L/minute. Among the patients with cough peak flow <=70 L/minute, 108 received NIV and 72 received conventional oxygen treatment. In this cohort, NIV reduced reintubation (9 % vs. 35 % at postextubation 72 h, p < 0.01; and 24 % vs. 49 % at postextubation 7 days, p < 0.01) and postextubation 90 day mortality (43 % vs. 61 %, p = 0.02) compared with the control group. Further, use of NIV was an independent protective factor for reintubation (OR = 0.19, p < 0.01 at 72 h postextubation; and OR = 0.33, p < 0.01 at 7 days postextubation) and for death at 90 days postextubation (OR = 0.40, p = 0.02). Among patients with cough peak flow >70 L/minute, 71 received NIV and 105 received conventional oxygen treatment. In this cohort, NIV did not reduce reintubation (6 % vs. 6 % at 72 h postextubation, p > 0.99; and 9 % vs. 9 % at 7 days postextubation, p > 0.99) or postextubation 90-day mortality (21 % vs. 15 %, p = 0.32) compared with the control group. Further, use of NIV was not associated with reintubation or postextubation 90-day mortality. CONCLUSION: In a planned extubated population, prophylactic NIV benefited patients with weak cough but possibly not in patients with strong cough. PMID- 27716406 TI - Pseudomonas mendocina native valve infective endocarditis: a case report. AB - BACKGROUND: Gram-negative microorganisms are uncommon pathogens responsible for infective endocarditis. Pseudomonas mendocina, a Gram-negative water-borne and soil-borne bacterium, was first reported to cause human infection in 1992. Since then, it has rarely been reported as a human pathogen in the literature. We describe the first case of native valve infective endocarditis due to P. mendocina in the USA. CASE PRESENTATION: A 57-year-old white man presented with bilateral large leg ulcers, fever, and marked leukocytosis. His past medical history included gout and chronic alcohol use. P. mendocina was isolated from his blood cultures. A comprehensive review of P. mendocina infection in the literature was performed. A total of eight cases of P. mendocina infection were reported in the literature. More than two-thirds of the cases of P. mendocina septicemia were associated with native valve infective endocarditis. Thus, an echocardiogram was performed and demonstrated mitral valve endocarditis with mild mitral insufficiency. His leg wounds were debrided and were probably the source of P. mendocina bacteremia. Unlike Pseudomonas aeruginosa, P. mendocina is susceptible to third-generation cephalosporins. Our patient received a 6-week course of antimicrobial therapy with a favorable clinical outcome. CONCLUSIONS: Our reported case and literature review illuminates a rare bacterial cause of infective endocarditis secondary to P. mendocina pathogen. Native cardiac valves were affected in all reported cases of infective endocarditis, and a majority of affected heart valves were left-sided. The antibiotics active against P. mendocina are different from those that are active against P. aeruginosa, and they notably include third-generation cephalosporins. The outcome of all reported cases of P. mendocina was favorable and no mortality was described. PMID- 27716404 TI - Clinicopathological characteristics of patients with amyotrophic lateral sclerosis resulting in a totally locked-in state (communication Stage V). AB - In the present study, we performed a comprehensive analysis to clarify the clinicopathological characteristics of patients with amyotrophic lateral sclerosis (ALS) that had progressed to result in a totally locked-in state (communication Stage V), in which all voluntary movements are lost and communication is impossible. In 11 patients, six had phosphorylated TAR DNA binding protein 43 (pTDP-43)-immunoreactive (ir) neuronal cytoplasmic inclusions (NCI), two had fused in sarcoma (FUS)-ir NCI, and three had copper/zinc superoxide dismutase (SOD1)-ir NCI. The time from ALS onset to the need for tracheostomy invasive ventilation was less than 24 months in ten patients. Regardless of accumulated protein, all the patients showed common lesions in the pallido-nigro-luysian system, brainstem reticular formation, and cerebellar efferent system, in addition to motor neurons. In patients with pTDP-43-ir NCI, patients with NCI in the hippocampal dentate granule neurons (DG) showed a neuronal loss in the cerebral cortex, and patients without NCI in DG showed a preserved cerebral cortex. By contrast, in patients with FUS-ir NCI, patients with NCI in DG showed a preserved cerebral cortex and patients without NCI in DG showed marked cerebral degeneration. The cerebral cortex of patients with SOD1-ir NCI was preserved. Together, these findings suggest that lesions of the cerebrum are probably not necessary for progression to Stage V. In conclusion, patients with ALS that had progressed to result in communication Stage V showed rapidly progressed symptoms, and their common lesions could cause the manifestations of communication Stage V. PMID- 27716407 TI - An adaptive detection method for fetal chromosomal aneuploidy using cell-free DNA from 447 Korean women. AB - BACKGROUND: Noninvasive prenatal testing (NIPT) using massively parallel sequencing of cell-free DNA (cfDNA) is increasingly being used to predict fetal chromosomal abnormalities. However, concerns over erroneous predictions which occur while performing NIPT still exist in pregnant women at high risk for fetal aneuploidy. We performed the largest-scale clinical NIPT study in Korea to date to assess the risk of false negatives and false positives using next-generation sequencing. METHODS: A total of 447 pregnant women at high risk for fetal aneuploidy were enrolled at 12 hospitals in Korea. They underwent definitive diagnoses by full karyotyping by blind analysis and received aneuploidy screening at 11-22 weeks of gestation. Three steps were employed for cfDNA analyses. First, cfDNA was sequenced. Second, the effect of GC bias was corrected using normalization of samples as well as LOESS and linear regressions. Finally, statistical analysis was performed after selecting a set of reference samples optimally adapted to a test sample from the whole reference samples. We evaluated our approach by performing cfDNA testing to assess the risk of trisomies 13, 18, and 21 using the sets of extracted reference samples. RESULTS: The adaptive selection algorithm presented here was used to choose a more optimized reference sample, which was evaluated by the coefficient of variation (CV), demonstrated a lower CV and higher sensitivity than standard approaches. Our adaptive approach also showed that fetal aneuploidies could be detected correctly by clearly splitting the z scores obtained for positive and negative samples. CONCLUSIONS: We show that our adaptive reference selection algorithm for optimizing trisomy detection showed improved reliability and will further support practitioners in reducing both false negative and positive results. PMID- 27716408 TI - The pre-synaptic vesicle protein synaptotagmin is a novel biomarker for Alzheimer's disease. AB - BACKGROUND: Synaptic degeneration is a central pathogenic event in Alzheimer's disease that occurs early during the course of disease and correlates with cognitive symptoms. The pre-synaptic vesicle protein synaptotagmin-1 appears to be essential for the maintenance of an intact synaptic transmission and cognitive function. Synaptotagmin-1 in cerebrospinal fluid is a candidate Alzheimer biomarker for synaptic dysfunction that also may correlate with cognitive decline. METHODS: In this study, a novel mass spectrometry-based assay for measurement of cerebrospinal fluid synaptotagmin-1 was developed, and was evaluated in two independent sample sets of patients and controls. Sample set I included cerebrospinal fluid samples from patients with dementia due to Alzheimer's disease (N = 17, age 52-86 years), patients with mild cognitive impairment due to Alzheimer's disease (N = 5, age 62-88 years), and controls (N = 17, age 41-82 years). Sample set II included cerebrospinal fluid samples from patients with dementia due to Alzheimer's disease (N = 24, age 52-84 years), patients with mild cognitive impairment due to Alzheimer's disease (N = 18, age 58-83 years), and controls (N = 36, age 43-80 years). RESULTS: The reproducibility of the novel method showed coefficients of variation of the measured synaptotagmin-1 peptide 215-223 (VPYSELGGK) and peptide 238-245 (HDIIGEFK) of 14 % or below. In both investigated sample sets, the CSF levels of synaptotagmin-1 were significantly increased in patients with dementia due to Alzheimer's disease (P <= 0.0001) and in patients with mild cognitive impairment due to Alzheimer's disease (P < 0.001). In addition, in sample set I the synaptotagmin-1 level was significantly higher in patients with mild cognitive impairment due to Alzheimer's disease compared with patients with dementia due to Alzheimer's disease (P <= 0.05). CONCLUSIONS: Cerebrospinal fluid synaptotagmin-1 is a promising biomarker to monitor synaptic dysfunction and degeneration in Alzheimer's disease that may be useful for clinical diagnosis, to monitor effect on synaptic integrity by novel drug candidates, and to explore pathophysiology directly in patients with Alzheimer's disease. PMID- 27716409 TI - A systematic review on the effectiveness of back protectors for motorcyclists. AB - BACKGROUND: Motorcyclists are a vulnerable road-user population who are overrepresented in traffic injuries. Utilisation of back protectors may be an effective preventive measure for spine injuries in motorcyclists. Since use of back protectors is increasing it is important that clinical evidence supports their use. The study aimed to investigate the current evidence on the ability of back protectors to reduce the rate of back injuries and patient mortality in motorcycle crashes. METHODS: A systematic literature search was conducted using various electronic databases. Systematic reviews, randomised controlled trials, controlled clinical trials, cohort studies, case series and case reports were included Opinion pieces and laboratory or biomechanical studies were excluded. Back protectors and spine protectors were included as the intervention; neck braces and speed humps were excluded. The target outcomes were any injuries to the back or death. Only English language studies were included. RESULTS: The search strategy yielded 185 studies. After excluding 183 papers by title and abstract and full-text evaluation, only two small cross-sectional studies were included. Foam inserts in motorcycle jackets and non-standard clothing may possibly be associated with higher risk of injuries, while hard shell and standard back protectors may possibly be associated with a reduced rate of back and spinal injury. CONCLUSION: This systematic review highlighted lack of appropriate evidence on efficacy of back protectors. Based on limited information, we are uncertain about the effects of back protectors on spinal injuries. Further research is required to substantiate the effects of back protectors on mortality and other injuries to the back. PMID- 27716410 TI - Seizure protein 6 and its homolog seizure 6-like protein are physiological substrates of BACE1 in neurons. AB - BACKGROUND: The protease BACE1 (beta-site APP cleaving enzyme) is a major drug target in Alzheimer's disease. However, BACE1 therapeutic inhibition may cause unwanted adverse effects due to its additional functions in the nervous system, such as in myelination and neuronal connectivity. Additionally, recent proteomic studies investigating BACE1 inhibition in cell lines and cultured murine neurons identified a wider range of neuronal membrane proteins as potential BACE1 substrates, including seizure protein 6 (SEZ6) and its homolog SEZ6L. METHODS AND RESULTS: We generated antibodies against SEZ6 and SEZ6L and validated these proteins as BACE1 substrates in vitro and in vivo. Levels of the soluble, BACE1 cleaved ectodomain of both proteins (sSEZ6, sSEZ6L) were strongly reduced upon BACE1 inhibition in primary neurons and also in vivo in brains of BACE1-deficient mice. BACE1 inhibition increased neuronal surface levels of SEZ6 and SEZ6L as shown by cell surface biotinylation, demonstrating that BACE1 controls surface expression of both proteins. Moreover, mass spectrometric analysis revealed that the BACE1 cleavage site in SEZ6 is located in close proximity to the membrane, similar to the corresponding cleavage site in SEZ6L. Finally, an improved method was developed for the proteomic analysis of murine cerebrospinal fluid (CSF) and was applied to CSF from BACE-deficient mice. Hereby, SEZ6 and SEZ6L were validated as BACE1 substrates in vivo by strongly reduced levels in the CSF of BACE1-deficient mice. CONCLUSIONS: This study demonstrates that SEZ6 and SEZ6L are physiological BACE1 substrates in the murine brain and suggests that sSEZ6 and sSEZ6L levels in CSF are suitable markers to monitor BACE1 inhibition in mice. PMID- 27716412 TI - Killing filarial nematode parasites: role of treatment options and host immune response. AB - BACKGROUND: There is compelling evidence that not only do anti-filarials significantly reduce larval forms, but that host immune responses also contribute to the clearance of filarial parasites; however, the underlying mechanisms have not been fully elucidated. MAIN TEXT: Filarial infections caused by Wuchereria bancrofti and Brugia species (lymphatic filariasis) and Onchocerca volvulus (onchocerciasis) affect almost 200 million individuals worldwide and pose major public health challenges in endemic regions. Indeed, the collective disability adjusted life years for both infections is 3.3 million. Infections with these thread-like nematodes are chronic and, although most individuals develop a regulated state, a portion develop severe forms of pathology. Mass drug administration (MDA) programmes on endemic populations focus on reducing prevalence of people with microfilariae, the worm's offspring in the blood, to less than 1 %. Although this has been successful in some areas, studies show that MDA will be required for longer than initially conceived. CONCLUSION: This paper highlights the mode of action of the various antifilarial treatment strategies and role of host immune response. PMID- 27716411 TI - Genetic, histochemical and biochemical studies on goat TSE cases from Cyprus. AB - Scrapie and bovine spongiform encephalopathy (BSE) are transmissible spongiform encephalopathies (TSE's) affecting sheep and goats. Susceptibility of goats to scrapie is influenced by polymorphisms of the prion protein gene (PRNP) of the host. Five polymorphisms are associated with reduced susceptibility to TSE's. In the study presented here caprine samples from a scrapie eradication program on Cyprus were genotyped and further characterized using BioRad TeSeE rapid test, histological, immunohistochemical and biochemical methods. In total 42 goats from 20 flocks were necropsied from which 25 goats showed a positive result in the rapid test, a spongiform encephalopathy and an accumulation of pathological prion protein (PrPSc) in the obex. PrPSc deposits were demonstrated in the placenta, peripheral nervous and lymphoreticular system. Two animals showed PrPSc accumulations in peripheral tissues only. By discriminatory immunoblots a scrapie infection could be confirmed for all cases. Nevertheless, slight deviations in the glycosylation pattern might indicate the presence of different scrapie strains. Furthermore scrapie samples from goats in the current study demonstrated less long term resistance to proteinase K than ovine or caprine BSE control samples. Reduced scrapie susceptibility according to the PRNP genotype was demonstrated (Fishers Exact test, p < 0.05) for the goats with at least one polymorphism (p = 0.023) at the six codons examined and in particular for those with polymorphisms at codon 146 (p = 0.016). This work characterizes scrapie in goats having implications for breeding and surveillance strategies. PMID- 27716413 TI - Pulmonary tumor diagnosed as an undifferentiated sarcoma with epithelioid features: a case report. AB - BACKGROUND: Pulmonary sarcomas are uncommon accounting for 0.5 % of all primary lung cancers. Undifferentiated sarcomas account for up to 20 % of soft tissue sarcomas. A lung tumor revealed to be an undifferentiated sarcoma with epithelioid features has never been reported in the literature. CASE PRESENTATION: A 61-year-old white Moroccan man presented with 2 months' history of hemoptysis and dyspnea. Chest computed tomography showed a cystic mass involving the lower field of his right lung evoking first a hydatid cyst. Abdominal computed tomography revealed bilateral adrenal nodules. Surgical resection of the lung mass was performed. On pathological examination, the tumor was cystic containing necrotic material. A histological diagnosis of undifferentiated sarcoma with epithelioid features was made. A positron emission tomography scan showed involvement of his pleura, left colon, adrenal glands, left thigh muscle, and leptomeninges. CONCLUSIONS: Undifferentiated sarcoma with epithelioid features is a rare malignant mesenchymal tumor. Clinical and radiological features are not specific. A differential diagnosis includes sarcomatoid carcinoma, malignant mesothelioma, melanoma, and other epithelioid sarcomas. PMID- 27716414 TI - Analyzing climate variations at multiple timescales can guide Zika virus response measures. AB - BACKGROUND: The emergence of Zika virus (ZIKV) in Latin America and the Caribbean in 2014-2016 occurred during a period of severe drought and unusually high temperatures, conditions that have been associated with the 2015-2016 El Nino event, and/or climate change; however, no quantitative assessment has been made to date. Analysis of related flaviviruses transmitted by the same vectors suggests that ZIKV dynamics are sensitive to climate seasonality and longer-term variability and trends. A better understanding of the climate conditions conducive to the 2014-2016 epidemic may permit the development of climate informed short and long-term strategies for ZIKV prevention and control. RESULTS: Using a novel timescale-decomposition methodology, we demonstrate that the extreme climate anomalies observed in most parts of South America during the current epidemic are not caused exclusively by El Nino or climate change, but by a combination of climate signals acting at multiple timescales. In Brazil, the dry conditions present in 2013-2015 are primarily explained by year-to-year variability superimposed on decadal variability, but with little contribution of long-term trends. In contrast, the warm temperatures of 2014-2015 resulted from the compound effect of climate change, decadal and year-to-year climate variability. CONCLUSIONS: ZIKV response strategies made in Brazil during the drought concurrent with the 2015-2016 El Nino event, may require revision in light of the likely return of rainfall associated with the borderline La Nina event expected in 2016-2017. Temperatures are likely to remain warm given the importance of long term and decadal scale climate signals. PMID- 27716415 TI - An evidence synthesis of the international knowledge base for new care models to inform and mobilise knowledge for multispecialty community providers (MCPs). AB - BACKGROUND: NHS England's Five Year Forward View (NHS England, Five Year Forward View, 2014) formally introduced a strategy for new models of care driven by simultaneous pressures to contain costs, improve care and deliver services closer to home through integrated models. This synthesis focuses on a multispecialty community provider (MCP) model. This new model of care seeks to overcome the limitations in current models of care, often based around single condition focused pathways, in contrast to patient-focused delivery (Royal College of General Practitioners, The 2022 GP: compendium of evidence, 2012) which offers greater continuity of care in recognition of complex needs and multimorbidity. METHODS: The synthesis, an innovative combination of best fit framework synthesis and realist synthesis, will develop a "blueprint" which articulates how and why MCP models work, to inform design of future iterations of the MCP model. A systematic search will be conducted to identify research and practice-derived evidence to achieve a balance that captures the historical legacy of MCP models but focuses on contemporary evidence. Sources will include bibliographic databases including MEDLINE, PreMEDLINE, CINAHL, Embase, HMIC and Cochrane Library; and grey literature sources. The Best Fit synthesis methodology will be combined with a synthesis following realist principles which are particularly suited to exploring what works, when, for whom and in what circumstances. DISCUSSION: The aim of this synthesis is to provide decision makers in health and social care with a practical evidence base relating to the multispecialty community provider (MCP) model of care. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016039552 . PMID- 27716416 TI - Human-biting activities of Anopheles species in south-central Ethiopia. AB - BACKGROUND: Indoor residual spraying (IRS) and long-lasting insecticidal nets (LLINs) are the key malaria vector control interventions in Ethiopia. The success of these interventions rely on their efficacy to repel or kill indoor feeding and resting mosquitoes. This study was undertaken to monitor human-biting patterns of Anopheles species in south-central Ethiopia. METHODS: Human-biting patterns of anophelines were monitored for 40 nights in three houses using human landing catches (HLC) both indoors and outdoors between July and November 2014, in Edo Kontola village, south-central Ethiopia. This time coincides with the major malaria transmission season in Ethiopia, which is usually between September and November. Adult mosquitoes were collected from 19:00 to 06:00 h and identified to species. Comparisons of HLC data were done using incidence rate ratio (IRR) calculated by negative binomial regression. The nocturnal biting activities of each Anopheles species was expressed as mean number of mosquitoes landing per person per hour. To assess malaria infections in Anopheles mosquitoes the presence of Plasmodium falciparum and P. vivax circumsporozoite proteins (CSP) were determined by enzyme-linked immunosorbent assay (ELISA). RESULTS: Altogether 3,408 adult female anophelines were collected, 2,610 (76.6 %) outdoors and 798 (23.4 %) indoors. Anopheles zeimanni was the predominant species (66.5 %) followed by An. arabiensis (24.8 %), An. pharoensis (6.8 %) and An. funestus (s.l.) (1.8 %). The overall mean anopheline density was 3.3 times higher outdoors than indoors (65.3 vs 19.9/person/night, IRR: 3.3, 95 % CI: 1.1-5.1, P = 0.001). The mean density of An. zeimanni, An. pharoensis and An. funestus (s.l.) collected outdoors was significantly higher than indoors for each species (P < 0.05). However, the mean An. arabiensis density outdoors was similar to that indoors (11.8 vs 9.4/person/night, IRR: 1.3, 95 % CI: 0.8-1.9, P = 0.335). The mean hourly human-biting density of An. arabiensis was greater outdoors than indoors and peaked between 21:00 and 22:00 h. However, An. arabiensis parous population showed high indoor man biting activities during bedtimes (22:00 to 05:00 h) when the local people were indoor and potentially protected by IRS and LLINs. All mosquito samples tested for CSP antigen were found negative to malaria parasites. CONCLUSIONS: Results show much greater mosquito human-biting activities occurring outdoors than indoors and during early parts of the night, implying higher outdoor malaria transmission potential in the area. However, high bedtime (22:00 to 05:00 h) indoor biting activities of parous An. arabiensis suggest high potential intervention impact of IRS and LLINs on indoor malaria transmission. PMID- 27716417 TI - Importance of rare gene copy number alterations for personalized tumor characterization and survival analysis. AB - It has proven exceedingly difficult to ascertain rare copy number alterations (CNAs) that may have strong effects in individual tumors. We show that a regulatory network inferred from gene expression and gene copy number data of 768 human cancer cell lines can be used to quantify the impact of patient-specific CNAs on survival signature genes. A focused analysis of tumors from six tissues reveals that rare patient-specific gene CNAs often have stronger effects on signature genes than frequent gene CNAs. Further comparison to a related network based approach shows that the integration of indirectly acting gene CNAs significantly improves the survival analysis. PMID- 27716418 TI - Shotgun proteomic analysis of Yersinia ruckeri strains under normal and iron limited conditions. AB - Yersinia ruckeri is the causative agent of enteric redmouth disease of fish that causes significant economic losses, particularly in salmonids. Bacterial pathogens differentially express proteins in the host during the infection process, and under certain environmental conditions. Iron is an essential nutrient for many cellular processes and is involved in host sensing and virulence regulation in many bacteria. Little is known about proteomics expression of Y. ruckeri in response to iron-limited conditions. Here, we present whole cell protein identification and quantification for two motile and two non motile strains of Y. ruckeri cultured in vitro under iron-sufficient and iron limited conditions, using a shotgun proteomic approach. Label-free, gel-free quantification was performed using a nanoLC-ESI and high resolution mass spectrometry. SWATH technology was used to distinguish between different strains and their responses to iron limitation. Sixty-one differentially expressed proteins were identified in four Y. ruckeri strains. These proteins were involved in processes including iron ion capture and transport, and enzymatic metabolism. The proteins were confirmed to be differentially expressed at the transcriptional level using quantitative real time PCR. Our study provides the first detailed proteome analysis of Y. ruckeri strains, which contributes to our understanding of virulence mechanisms of Y. ruckeri, and informs development of novel control methods for enteric redmouth disease. PMID- 27716419 TI - The impact of mild induced hypothermia on the rate of transfusion and the mortality in severely injured patients: a retrospective multi-centre study. AB - BACKGROUND: Although under discussion, induced hypothermia (IH) is an established therapy for patients with cardiac arrest or traumatic brain injuries. The influences on coagulopathy and bleeding tendency in severely injured patients (SIP) with concomitant traumatic brain injury are most widely unclear. Therefore, the aim of this study was to quantify the effect of mild IH in SIP with concomitant severe traumatic brain injuries on transfusion rate and mortality. METHODS: In this retrospective multi-centre study, SIP from three European level 1 trauma centres with an ISS >=16 between 2009 and 2011 were included. At hospital A, patients qualified for IH with age <=70 years and a severe head injury with an abbreviated injury scale (AISHead) of >=3. IH was defined as target core body temperature of 35 degrees C. Hypothermic patients were matched with two patients, one from hospital B and one from hospital C using age and AISHead. The effect of IH on the transfusion rate, complications and mortality was quantified with 95 % confidence intervals (CI). Patients not treated with IH in hospital A and those from hospital B and C, who were not matched, were used to adjust the CI for the effect of inter-hospital therapy protocol differences. RESULTS: Mean age of patients in the IH-group (n = 43) was 35.7 years, mean ISS 30 points and sex distribution showed 83.7 % male. Mean age of matched patients in the normotherm-group (n = 86) was 36.7 years, mean ISS 33 points and there were 75.6 % males. For the hypothermic patients, we pointed out an estimate of mean difference for the number of transfused units of packed red blood cells as well as for mortality which does not indicate a decrease in the benefit gained by hypothermia. It is suggested that hypothermic patients tend to a higher rate of lung failure and thromboembolisms. CONCLUSION: Though tending to an increased rate of complications, there is no evidence for a difference in both; rate of transfusion and mortality in SIP. Mild IH as an option for severe head injuries seems as well-being practicable in the presence of multiple severe injuries. Further, clinical studies regarding the side effects are necessary. PMID- 27716420 TI - Household perceptions and subjective valuations of indoor residual spraying programmes to control malaria in northern Uganda. AB - BACKGROUND: Insecticide-based tools remain critical for controlling vector-borne diseases in Uganda. Securing public support from targeted populations for such tools is an important component in sustaining their long-run effectiveness. Yet little quantitative evidence is available on the perceived benefits and costs of vector control programmes among targeted households. METHODS: A survey was administered to a clustered random sample of 612 households in Gulu and Oyam districts of northern Uganda during a period of very high malaria transmission and following a pilot indoor residual spray (IRS) programme. A discrete choice experiment was conducted within the survey, in which respondents indicated their preferences for different IRS programmes relative to money compensation in a series of experimentally controlled, hypothetical choice sets. The data were analysed using conditional logit regression models to estimate respondents' willingness to accept (WTA) some amount of money compensation in lieu of foregone malaria risk reductions. Latent class models were used to analyse whether respondent characteristics predicted WTA. RESULTS: Average WTA is estimated at $8.94 annually for a 10 % reduction in malaria risk, and additional co-benefits of IRS were estimated to be worth on average $54-$56 (depending on insecticide type) per round of IRS. Significant heterogeneity is observed: Four in five household heads in northern Uganda have high valuations for IRS programmes, while the remaining 20 % experience costly side effects of IRS (valued at between $2 and $3 per round). Statistically significant predictors of belonging to the high value group include respondent gender, mean age of household members, participation in previous IRS, basic knowledge of mosquito reproduction, and the number of mosquito nets owned. Proxies for household income and wealth are not found to be statistically significant predictors of WTA. CONCLUSIONS: This study suggests that the majority of people in areas of high malaria transmission like northern Uganda place a high value on vector control programmes using IRS. However, there is significant heterogeneity in terms of the perceived side effects (positive and negative). This has implications for sustaining public support for these programmes in the long-term. PMID- 27716421 TI - A spatial analysis of human Schistosoma japonicum infections in Hubei, China, during 2009-2014. AB - BACKGROUND: The province of Hubei is located in the middle of China, near the middle and lower reaches of the River Yangtze, and is an area where schistosomiasis is endemic. It is challenging to control this disease in this environment, and it would be useful to identify clusters of infection and transmission, as well as their distributions during recent years. Therefore, this study aimed to analyze the spatial distribution of schistosomiasis in Hubei, in order to facilitate the effective control and elimination of this disease. METHODS: We collected schistosomiasis surveillance data from all endemic counties in Hubei during 2009-2014. A geographical information system (ArcGIS, version 10.1) was used to link the counties' geographical data with the epidemiological data, and the spatial scanning method (FleXScan v3.1.2) was used to identify spatial clusters of human infections with Schistosoma japonicum. RESULTS: In Hubei, patients who exhibited stool test results that were positive for S. japonicum accounted for > 50 % of all cases in China during 2009-2014. However, each endemic county in Hubei exhibited a declining trend in the number of human S. japonicum infections during the study period. The ArcGIS analyses revealed that the middle reaches of the River Yangtze were highly endemic for S. japonicum infections. Spatial scan analyses revealed the following infection clusters: two clusters in ten counties during 2009, two clusters in nine counties during 2010, three clusters in 12 counties during 2011, two clusters in 12 counties during both 2012 and 2013 and two clusters in ten counties during 2014. Most of the cluster regions were located in the lake and marshland regions along the basins of the River Yangtze. CONCLUSION: We successfully identified schistosomiasis clusters at the county level in Hubei during 2009-2014, and our results revealed that the clusters were typically located in lake and marshland regions. These data may be useful for controlling and eliminating schistosomiasis in other high risk areas. PMID- 27716423 TI - Vitamin B12 deficiency in metformin-treated type-2 diabetes patients, prevalence and association with peripheral neuropathy. AB - BACKGROUND: The association between long-term metformin use and low vitamin B12 levels has been proven. However, the prevalence estimates of metformin-induced vitamin B12 deficiency showed considerable variation among the studies. The potential of the deficiency to cause or worsen peripheral neuropathy in type-2 diabetes mellitus (T2DM) patients has been investigated with conflicting results. The aim of the study was to investigate: 1) the prevalence of vitamin B12 deficiency in T2DM patients on metformin; 2) the association between vitamin B12 and peripheral neuropathy; 3) and the risk factors for vitamin B12 deficiency in these patients. METHODS: In this cross-sectional study, consecutive metformin treated T2DM patients attending diabetes clinics of two public hospitals in South Africa were approached for participation. Participation included measuring vitamin B12 levels and assessing peripheral neuropathy using Neuropathy Total Symptom Score-6 (NTSS-6) questionnaire. The prevalence of vitamin B12 deficiency (defined by concentrations <150 pmol/L) was determined. Those with NTSS-6 scores >6 were considered to have peripheral neuropathy. The relationship between vitamin B12 and peripheral neuropathy was investigated when the two variables were in the binary and continuous forms. Multiple logistic regression was used to determine risk factors for vitamin B12 deficiency. RESULTS: Among 121 participants, the prevalence of vitamin B12 deficiency was 28.1 %. There was no difference in presence of neuropathy between those with normal and deficient vitamin levels (36.8 % vs. 32.3 %, P = 0.209). Vitamin B12 levels and NTSS-6 scores were not correlated (Spearman's rho =0.056, P = 0.54). HbA1c (mmol/mol) (OR = 0.97, 95 % CI: 0.95 to 0.99, P = 0.003) and black race (OR = 0.34, 95 % CI: 0.13 to 0.92, P = 0.033) were risk factors significantly associated with vitamin B12 deficiency. Metformin daily dose (gram) showed borderline significance (OR = 1.96, 95 % CI: 0.99 to 3.88, P = 0.053). CONCLUSIONS: Close to third of metformin treated T2DM patients had vitamin B12 deficiency. The deficiency was not associated with peripheral neuropathy. Black race was a protective factor for vitamin B12 deficiency. PMID- 27716422 TI - A statistical analysis plan for the efficiency and safety of Chinese herbal medicine used concurrently with topical therapy for psoriasis vulgaris. AB - BACKGROUND: Psoriasis vulgaris (PV) has been causing increasing concern due to its highly prevalent, harmful and therapy-resistant characteristics. The YXBCM01 (Chinese herbal medicine) for PV trial evaluates the effects of YXBCM01 on relapse rate in patients suffering from PV. As an update to the published design and method for the trial, this paper presents the statistical plan for the main publication to avoid the risk of outcome reporting bias, selective reporting, and data-driven results. METHODS/DESIGN: This trial is a multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial. A total of 600 PV patients (300 in each group) will be randomized to one of two arms: participants in the experimental group will receive the YXBCM01 granule 5.5 g twice daily for 12 weeks. Placebo granules are given to patients in the control group at a dose of 5.5 g twice daily for 12 weeks. The sequential topical therapy is administrated simultaneously to all eligible patients by using calcipotriol betamethasone ointment once daily (a treatment area of up to 30 % body surface area (BSA), fingertip unit is recommended) in the first 4 weeks (maximum of 100 g weekly), followed by calcipotriol betamethasone ointment once daily for the remaining 8 weeks (maximum of 100 g weekly). The primary outcome measure is relapse rate in the treatment period and follow-up period. The secondary outcome measures include time to relapse, time to onset, rebound rate, cumulative consumption of topical medicine, visual analog scale (VAS), BSA, the Dermatology Life Quality Index (DLQI) and the Medical Outcomes Study (MOS) 36-item short form health survey (SF-36). CONCLUSIONS: Application of this statistical analysis plan to the YXBCM01 for PV trial will facilitate unbiased evaluation of these important clinical data. This study will provide evidence regarding the value of YXBCM01 as an intervention for PV patients.

Br extract in vitro and in ovalbumin-induced mouse model. AB - BACKGROUND: Asthma is an increasing global health problem, and novel strategies to prevent or ameliorate the condition are needed. Here, the effects of 80 % ethanol extracts of Salvia plebeia R. Br. (SE) on an induced inflammatory response were investigated. RESULTS: Salvia plebeia R. Br. inhibited production of pro-inflammatory cytokines, such as TNF-alpha and IL-6, as well as nitric oxide (NO) in LPS-stimulated RAW 264.7 cells. NO and pro-inflammatory cytokine production was suppressed more effectively by SE of the aerial parts (SE-A) than of the roots (SE-R) of S. plebeia. In BEAS-2B cells, both SE-A and SE-R inhibited the increase in production of the inflammatory cytokines IL-6 and IL-8. We also investigated the anti-asthmatic effects of SE in an ovalbumin (OVA)-induced BALB/c mouse model. SE-A treatment significantly reduced the number of airway eosinophils, IL-4 and IL-13 levels, mucus production, and inflammatory infiltration, as compared with the corresponding levels in the untreated, OVA induced mice, and had similar effects to dexamethasone. CONCLUSIONS: Salvia plebeia ethanol extract ameliorated the induced inflammatory response in RAW 264.7 and BEAS-2B cells, with more effective inhibition noted for SE-A than for SE-R. SE-A treatment was effective in improving the histopathological changes in the lungs of asthma model mice via modulation of eosinophils and Th2 cytokines. These results suggest that SE-A can be considered as a therapeutic agent that can potentially relieve asthma. PMID- 27716425 TI - Flank pseudohernia following posterior rib fracture: a case report. AB - BACKGROUND: A pseudohernia is an abdominal wall bulge that may be mistaken for a hernia but that lacks the disruption of the abdominal wall that characterizes a hernia. Thus, the natural history and treatment of this condition differ from those of a hernia. This is the first report of a pseudohernia due to cough associated rib fracture. CASE PRESENTATION: A case of pseudohernia due to fractures of the 10th and 11th ribs in a 68-year-old white woman is presented. The patient suffered from a major coughing episode 1 year prior to her presentation, after which she noted a progressively enlarging bulge in her left flank. Computed tomography demonstrated a bulge in the abdominal wall containing bowel and spleen but with all muscle and fascial layers intact; in addition, lateral 10th rib and posterior 11th rib fractures were noted. CONCLUSIONS: As there was no defect in muscle or fascia, we diagnosed a pseudohernia, likely due to a denervation injury from the fractured ribs. Symptomatic treatment was recommended, including wearing a corset and referral to a pain management clinic. Symptomatic treatment is thought to be the mainstay of therapy for pseudohernias, as surgical intervention is unlikely to be of benefit. PMID- 27716426 TI - Mean platelet volume in children with hepatitis A. AB - BACKGROUND: Mean platelet volume (MPV), which is commonly used as a measure of platelet size, indicates the rate of platelet production and platelet activation. We aimed to evaluate the mean platelet volume in children with hepatitis A. METHODS: In this retrospective case-controlled study, the study population consisted of 62 children with hepatitis A and 62 healthy control subjects. RESULTS: MPV values, aspartate transaminase (AST), and alanine transaminase (ALT) levels on admission were significantly increased in patients with hepatitis A when compared to controls whereas white blood cell (WBC) counts were significantly lower. Two weeks after admission, the MPV values showed a significant decrease from 9.47 +/- 1.62 to 8.84 +/- 1.48 fL in patients with hepatitis A, but these values were still significantly higher than the controls. There was a significant difference in terms of MPV, WBC, AST, and ALT values between the controls and the patient group 2 weeks after admission. CONCLUSIONS: This study is the first to evaluate the MPV levels in children with hepatitis A. MPV values were found to be increased in children hospitalized with hepatitis A. PMID- 27716428 TI - Successful use of rivaroxaban in postoperative deep vein thrombosis of the lower limb following instability with warfarin: a case report. AB - BACKGROUND: Evidence from clinical trials shows rivaroxaban to be effective for the treatment of deep vein thrombosis. Switching to rivaroxaban following failure of indirect anticoagulants in deep vein thrombosis has not been demonstrated in a real-life setting. CASE PRESENTATION: A 43-year-old white woman was switched from warfarin to rivaroxaban for the treatment of thrombosis of her right common femoral vein after saphenectomy. The reason for the switch was due to the instability of anti-coagulation therapy with vitamin K antagonists over a period of 3 months during which she did not reach the "therapeutic range" of prothrombin time-international normalized ratio. The ineffectiveness of the conventional oral anticoagulant was confirmed by persistence of moderate-high values of fibrin D dimers (780 ng/ml) and by residual vein thrombosis at an ultrasound examination. Objectively, her right leg appeared to be still edematous and warm and pain was elicited by deep palpation. Rivaroxaban was administered after warfarin discontinuation (prothrombin time-international normalized ratio = 1.43) at a dosage of 15 mg every 12 hours for 3 weeks, followed by 20 mg once daily for 3 months. After this period, her objective symptoms significantly improved, with reduction of edema of her lower limb and pain relief. Her fibrin D dimer values returned to normal (210 ng/ml). An ultrasound showed recanalization of the obstructed venous segment. CONCLUSIONS: In this case report, a switch to rivaroxaban from warfarin was shown to be effective and safe for the treatment of postoperative deep vein thrombosis, whereas standard oral anticoagulation therapy, which required dose adjustments over a period of 3 months, was not able to stabilize the therapeutic range of prothrombin time-international normalized ratio nor improve our patient's outcome. PMID- 27716427 TI - A functional variant of TLR10 modifies the activity of NFkB and may help predict a worse prognosis in patients with rheumatoid arthritis. AB - BACKGROUND: Toll-like receptor (TLR) family members are key players in inflammation. TLR10 has been poorly studied in chronic inflammatory disorders, and its clinical relevance in rheumatoid arthritis (RA) is as yet unknown. We aimed at identifying TLR10 variants within all coding regions of the gene in patients with RA as well as studying their functional and clinical significance. METHODS: TLR10 gene variants were studied by performing sequencing of 66 patients with RA and 30 control subjects. A selected variant, I473T, was then analyzed in 1654 patients and 1702 healthy control subjects. The capacity of this TLR10 variant to modify the transcriptional activity of nuclear factor kappa-light chain-enhancer of activated B cells (NFkB) was determined by using a luciferase reporter assay and analyzing the expression of NFkB target genes by quantitative polymerase chain reaction. Differences between groups were analyzed by using the Mann-Whitney U test and the unpaired two-tailed Student's t test. RESULTS: We detected ten missense variants in the TLR10 gene and focused on the I473T substitution based on allele frequencies and the predicted functional impact. I473T variant is not associated with susceptibility to RA, but it significantly correlates with erosive disease in patients seropositive for antibodies to citrullinated protein antigens (p = 0.017 in the total cohort and p = 0.0049 in female patients) and with a lower response to infliximab treatment as measured by the change in Disease Activity Score in 28 joints (p = 0.012) and by the European League Against Rheumatism criteria (p = 0.049). Functional studies showed that TLR10 reduced activation of the NFkB inflammatory pathway in hematopoietic cells, whereas the I473T variant lacked this inhibitory capacity. Consistently, after exposure to infliximab, cells expressing the I437T variant showed higher NFkB activity than cells carrying wild-type TLR10. CONCLUSIONS: A TLR10 allelic variant, I473T, has impaired NFkB inhibitory activity and is highly associated with disease severity and low response to infliximab in patients with RA. PMID- 27716429 TI - Serosurveillance of viral pathogens circulating in West Africa. AB - BACKGROUND: Sub-Saharan Africa is home to a variety of pathogens, but disease surveillance and the healthcare infrastructure necessary for proper management and control are severely limited. Lassa virus, the cause of Lassa fever, a severe hemorrhagic fever in humans is endemic in West Africa. In Sierra Leone at the Kenema Government Hospital Lassa Diagnostic Laboratory, up to 70 % of acute patient samples suspected of Lassa fever test negative for Lassa virus infection. This large amount of acute undiagnosed febrile illness can be attributed in part to an array of hemorrhagic fever and arthropod-borne viruses causing disease that goes undetected and untreated. METHODS: To better define the nature and extent of viral pathogens infecting the Sierra Leonean population, we developed a multiplexed MAGPIX(r) assay to detect IgG antibodies against Lassa, Ebola, Marburg, Rift Valley fever, and Crimean-Congo hemorrhagic fever viruses as well as pan-assays for flaviviruses and alphaviruses. This assay was used to survey 675 human serum samples submitted to the Lassa Diagnostic Laboratory between 2007 and 2014. RESULTS: In the study population, 50.2 % were positive for Lassa virus, 5.2 % for Ebola virus, 10.7 % for Marburg virus, 1.8 % for Rift Valley fever virus, 2.0 % for Crimean-Congo hemorrhagic fever virus, 52.9 % for flaviviruses and 55.8 % for alphaviruses. CONCLUSIONS: These data exemplify the importance of disease surveillance and differential diagnosis for viral diseases in Sierra Leone. We demonstrate the endemic nature of some of these viral pathogens in the region and suggest that unrecognized outbreaks of viral infection have occurred. PMID- 27716430 TI - A specific anti-citrullinated protein antibody profile identifies a group of rheumatoid arthritis patients with a toll-like receptor 4-mediated disease. AB - BACKGROUND: Increased expression of toll-like receptor 4 (TLR4) and its endogenous ligands, is characteristic of rheumatoid arthritis (RA) synovitis. In this study, we evaluated how these TLR4 ligands may drive pathogenic processes and whether the fine profiling of anti-citrullinated protein antibodies (ACPA) based on their target specificity might provide a simple means to predict therapeutic benefit when neutralizing TLR4 in this disease. METHODS: The capacity of RA synovial fluids (RASF) to stimulate cytokine production in monocytes from patients with RA was analyzed by ELISA. The presence of TLR4 activators in RASF was determined by measuring the levels of ACPA, ACPA subtypes with reactivity to specific citrullinated peptides and other TLR4 ligands. Neutralization of TLR4 signaling was investigated using NI-0101, a therapeutic antibody that targets TLR4. RESULTS: RASF exhibited a heterogeneous capacity to induce production of proinflammatory cytokines by monocytes isolated from patients with RA. Such cytokine responses were significantly modified by TLR4 blockade achieved using NI 0101. The analysis of the content of RASF and matched sera demonstrated that ACPA fine specificities in patient samples predict cellular response to anti-TLR4 exposure in vitro. CONCLUSION: TLR4 represents a possible therapeutic target in RA. Our study demonstrates that TLR4 inhibition in an ex vivo model of RA pathogenesis can significantly modulate cytokine release and does so in specific subgroups of RA patient-derived samples. It also suggests that ACPA fine profiling has the potential to identify RA patients with a predominantly TLR4 driven pathotype that could be used to predict preferential response to TLR4 antagonism. PMID- 27716431 TI - Tor1a+/- mice develop dystonia-like movements via a striatal dopaminergic dysregulation triggered by peripheral nerve injury. AB - Isolated generalized dystonia is a central motor network disorder characterized by twisted movements or postures. The most frequent genetic cause is a GAG deletion in the Tor1a (DYT1) gene encoding torsinA with a reduced penetrance of 30-40 % suggesting additional genetic or environmental modifiers. Development of dystonia-like movements after a standardized peripheral nerve crush lesion in wild type (wt) and Tor1a+/- mice, that express 50 % torsinA only, was assessed by scoring of hindlimb movements during tail suspension, by rotarod testing and by computer-assisted gait analysis. Western blot analysis was performed for dopamine transporter (DAT), D1 and D2 receptors from striatal and quantitative RT-PCR analysis for DAT from midbrain dissections. Autoradiography was used to assess the functional DAT binding in striatum. Striatal dopamine and its metabolites were analyzed by high performance liquid chromatography. After nerve crush injury, we found abnormal posturing in the lesioned hindlimb of both mutant and wt mice indicating the profound influence of the nerve lesion (15x vs. 12x relative to control) resembling human peripheral pseudodystonia. In mutant mice the phenotypic abnormalities were increased by about 40 % (p < 0.05). This was accompanied by complex alterations of striatal dopamine homeostasis. Pharmacological blockade of dopamine synthesis reduced severity of dystonia-like movements, whereas treatment with L-Dopa aggravated these but only in mutant mice suggesting a DYT1 related central component relevant to the development of abnormal involuntary movements. Our findings suggest that upon peripheral nerve injury reduced torsinA concentration and environmental stressors may act in concert in causing the central motor network dysfunction of DYT1 dystonia. PMID- 27716432 TI - Transmission of methicillin-resistant Staphylococcus aureus in long-term care facilities and their related healthcare networks. AB - BACKGROUND: Long-term care facilities (LTCF) are potential reservoirs for methicillin-resistant Staphylococcus aureus (MRSA), control of which may reduce MRSA transmission and infection elsewhere in the healthcare system. Whole-genome sequencing (WGS) has been used successfully to understand MRSA epidemiology and transmission in hospitals and has the potential to identify transmission between these and LTCF. METHODS: Two prospective observational studies of MRSA carriage were conducted in LTCF in England and Ireland. MRSA isolates were whole-genome sequenced and analyzed using established methods. Genomic data were available for MRSA isolated in the local healthcare systems (isolates submitted by hospitals and general practitioners). RESULTS: We sequenced a total of 181 MRSA isolates from the two study sites. The majority of MRSA were multilocus sequence type (ST)22. WGS identified one likely transmission event between residents in the English LTCF and three putative transmission events in the Irish LTCF. WGS also identified closely related isolates present in colonized Irish residents and their immediate environment. Based on phylogenetic reconstruction, closely related MRSA clades were identified between the LTCF and their healthcare referral network, together with putative MRSA acquisition by LTCF residents during hospital admission. CONCLUSIONS: These data confirm that MRSA is transmitted between residents of LTCF and is both acquired and transmitted to others in referral hospitals and beyond. Our data present compelling evidence for the importance of environmental contamination in MRSA transmission, reinforcing the importance of environmental cleaning. The use of WGS in this study highlights the need to consider infection control in hospitals and community healthcare facilities as a continuum. PMID- 27716433 TI - Utilization of screening mammography in older women according to comorbidity and age: protocol for a systematic review. AB - BACKGROUND: Approximately half of new invasive breast cancer cases diagnosed each year in the United States occur among women aged 65 years and older. The increasing life expectancy coupled with the attendant rise in breast cancer incidence and elimination of out-of-pocket expenses for screening mammography as a result of the Affordable Care Act could lead to higher utilization rates of screening mammography. Although research indicates that life expectancy should be a strong consideration when making screening decisions among older women, the extent to which screening mammography utilization is tailored to comorbidity and life expectancy is not well established. METHODS/DESIGN: To identify relevant studies, a systematic search of the literature will be conducted using PubMed and EMBASE between January 1, 1991, and March 1, 2016. Additional studies will be found through citation review or by contacting experts in the field. The inclusion criteria will be any study design comprised of women aged 65 and older, assessing women's comorbidity, functional impairments, and/or health status, and reporting outcome measures that addressed mammography utilization within the last 1-5 years. For each study, two authors will independently abstract data regarding study eligibility and outcomes to determine relevance. Quantitative results will be extracted from text and tables, choosing preferably those adjusted for important confounders. DISCUSSION: The review will provide evidence on the impact of comorbidity, functional limitations, and health status on screening mammography utilization in older women and inform decision aids in this area. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016032661. PMID- 27716435 TI - Lessons on malaria control in the ethnic minority regions in Northern Myanmar along the China border, 2007-2014. AB - BACKGROUND: For many countries where malaria is endemic, the burden of malaria is high in border regions. In ethnic minority areas along the Myanmar-China border, residents have poor access to medical care for diagnosis and treatment, and there have been many malaria outbreaks in such areas. Since 2007, with the support of the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM), a malaria control project was introduced to reduce the malaria burden in several ethnic minority regions. METHODS: A malaria control network was established during the period from 2007 to 2014. Multiple malaria interventions, including diagnosis, treatment, distribution of LLINs and health education, were conducted to improve the accessibility and quality of malaria control services for local residents. Annual cross-sectional surveys were conducted to evaluate intervention coverage and indicators of malaria transmission. RESULTS: In ethnic minority regions where a malaria control network was established, both the annual malaria incidence (19.1 per thousand per year, in 2009; 8.7, in 2014) and malaria prevalence (13.6 % in 2008; 0.43 % in 2014) decreased dramatically during the past 5-6 years. A total of 851 393 febrile patients were detected, 202 598 malaria cases (including confirmed cases and suspected cases) were treated, and 759 574 LLINs were delivered to populations at risk. Of households in 2012, 73.9 % had at least one ITNs/LLINs (vs. 28.3 %, in 2008), and 50.7 % of children less than 5 years and 50.3 % of pregnant women slept under LLINs the night prior to their visit. Additionally, malaria knowledge was improved in 68.4 % of residents. CONCLUSION: There has been great success in improving malaria control in these regions from 2007 to 2014. Malaria burdens have decreased, especially in KOK and WA. The continued maintenance of sustainable malaria control networks in these regions may be a long-term process, due to regional conflicts and the lack of funds, technology, and health workers. Furthermore, information and scientific support from the international community should be offered to these ethnic minority regions to uphold recent achievements. PMID- 27716436 TI - Are ethical norms and current policies still relevant in face of the recent mass terror events? AB - The widespread utilization of social media in recent terror attacks in major European cities should raise a "red flag" for the emergency medical response teams. The question arises as to the impact of social media during terror events on the healthcare system. Information was published well before any emergency authority received a distress call or was requested to respond. Photos published at early stages of the attacks, through social media were uncensored, presenting identifiable pictures of victims. Technological advancements of recent years decrease and remove barriers that enable the public to use them as they see fit. These attacks raise ethical considerations for the patients and their rights as they were outsourced from the medical community, into the hands of the public. The healthcare system should leverage social media and its advantages in designing response to terror, but this requires a re-evaluation and introspection into the current emergency response models. PMID- 27716434 TI - Oestrogen-induced angiogenesis and implantation contribute to the development of parasitic myomas after laparoscopic morcellation. AB - BACKGROUND: Iatrogenic parasitic myomas (PMs), caused by intra-corporeal power morcellation during laparoscopy is gradually increasing. However, the pathogenesis and medical treatment of PMs remain largely unelucidated. METHODS: Laparoscopically-induced PM xenografted mouse model was conducted by xenografting human uterine myoma fragments into the abdominal cavity of SCID mice and hormonal manipulation was performed using this mouse model to demonstrate the role of oestrogen in the development of implanted PMs. Immunohistochemistry of oestrogen receptor alpha (ERalpha), progesterone receptor (PR), vimentin, vascular endothelial growth factor (VEGF), microvessel density (MVD) and Ki-67 index was performed and compared. RESULTS: In the patient with PMs, ERalpha, PR, angiogenesis and proliferative property expression were upregulated in PM lesions compared to uterine myomas. In the laparoscopically-induced PM mouse model, implanted myomas had more steroid receptor expressions, angiogenesis and proliferative property compared with pre-xenografted or non-implanted myoma. Depletion of oestrogen in the ovariectomized (OVX) mice decreased laparoscopically-induced PM implantations. In comparison, the implantations of PMs were increased with additional E2 supplement. Hormonal manipulation in the PM mouse model, including AI, GnRHa and SERM groups, were compared and AI significantly decreased the implantations, steroid receptor, angiogenesis, cell density, and proliferative index of PMs compared with control group. Furthermore, GnRHa significantly decreased VEGF and MVD expressions compared with control group. CONCLUSIONS: These data highlight the crucial role of oestrogen in the development of laparoscopically-induced PMs and suggest that hormone manipulation may be a potential therapeutic agent. TRIAL REGISTRATION: This protocol was approved by the Human and Animal Institutional Review Board of Taipei Veterans General Hospital ( VGHIRB No 2014-10-002C on Nov. 17th, 2014; IACUC 2014-119 on Aug. 22nd, 2014). PMID- 27716437 TI - Effects of developmental exposure to silver in ionic and nanoparticle form: A study in rats. AB - BACKGROUND: Evaluations of silver in both nanoparticle (Ag-NPs) and ionic forms indicate some adverse effects on living organisms, but little is known about their potential for developmental toxicity. In this study, developmental toxicity of Ag-NPs (from 0.2 to 20 mg/kg/day) and ionic Ag (AgNO3, 20 mg Ag/kg/day) were investigated in rats. METHODS: Animals were dosed by gavage from gestation day 7 20. The day after parturition, dams and pups were sacrificed and Ag level assessed in several maternal and pup organs. In addition, hepatotoxicity and oxidative stress parameters and histopathology were evaluated. RESULTS: No treatment related effects were found for gestational parameters including pregnancy length, maternal weight gain, implantations, birth weight and litter size at any dose level of Ag-NPs. Maternal weight gain was lower in dams receiving AgNO3 compared to the other groups, suggesting that the ionic form may exert a higher degree of toxicity compared to the NP form. Tissue contents of Ag were higher in all treated groups compared to control dams and pups, indicating transfer of Ag across the placenta. The findings furthermore suggest that Ag may induce oxidative stress in dams and their offspring, although significant induction was only observed after dosing with AgNO3. Histopathological examination of brain tissue revealed a high incidence of hippocampal sclerosis in dams treated with nanoparticle as well as ionic Ag. CONCLUSION: The difference in offspring deposition patterns between ionic and NP Ag and the observations in dam brain tissue, requires scrutiny, and, if corroborated, indicate that ionic and NP forms maybe need separate risk assessments and that the hazard ratings of silver in both ionic and nanoparticle forms should be increased, respectively. TRIAL REGISTRATION: Not applicable. Developmental Toxicity of Ag-NPs. PMID- 27716438 TI - The impact of co-infections on fish: a review. AB - Co-infections are very common in nature and occur when hosts are infected by two or more different pathogens either by simultaneous or secondary infections so that two or more infectious agents are active together in the same host. Co infections have a fundamental effect and can alter the course and the severity of different fish diseases. However, co-infection effect has still received limited scrutiny in aquatic animals like fish and available data on this subject is still scarce. The susceptibility of fish to different pathogens could be changed during mixed infections causing the appearance of sudden fish outbreaks. In this review, we focus on the synergistic and antagonistic interactions occurring during co infections by homologous or heterologous pathogens. We present a concise summary about the present knowledge regarding co-infections in fish. More research is needed to better understand the immune response of fish during mixed infections as these could have an important impact on the development of new strategies for disease control programs and vaccination in fish. PMID- 27716439 TI - Effect of timing of hip extension assistance during loaded walking with a soft exosuit. AB - BACKGROUND: Recent advances in wearable robotic devices have demonstrated the ability to reduce the metabolic cost of walking by assisting the ankle joint. To achieve greater gains in the future it will be important to determine optimal actuation parameters and explore the effect of assisting other joints. The aim of the present work is to investigate how the timing of hip extension assistance affects the positive mechanical power delivered by an exosuit and its effect on biological joint power and metabolic cost during loaded walking. In this study, we evaluated 4 different hip assistive profiles with different actuation timings: early-start-early-peak (ESEP), early-start-late-peak (ESLP), late-start-early peak (LSEP), late-start-late-peak (LSLP). METHODS: Eight healthy participants walked on a treadmill at a constant speed of 1.5 m . s-1 while carrying a 23 kg backpack load. We tested five different conditions: four with the assistive profiles described above and one unpowered condition where no assistance was provided. We evaluated participants' lower limb kinetics, kinematics, metabolic cost and muscle activation. RESULTS: The variation of timing in the hip extension assistance resulted in a different amount of mechanical power delivered to the wearer across conditions; with the ESLP condition providing a significantly higher amount of positive mechanical power (0.219 +/- 0.006 W . kg-1) with respect to the other powered conditions. Biological joint power was significantly reduced at the hip (ESEP and ESLP) and at the knee (ESEP, ESLP and LSEP) with respect to the unpowered condition. Further, all assistive profiles significantly reduced the metabolic cost of walking compared to the unpowered condition by 5.7 +/- 1.5 %, 8.5 +/- 0.9 %, 6.3 +/- 1.4 % and 7.1 +/- 1.9 % (mean +/- SE for ESEP, ESLP, LSEP, LSLP, respectively). CONCLUSIONS: The highest positive mechanical power delivered by the soft exosuit was reported in the ESLP condition, which showed also a significant reduction in both biological hip and knee joint power. Further, the ESLP condition had the highest average metabolic reduction among the powered conditions. Future work on autonomous hip exoskeletons may incorporate these considerations when designing effective control strategies. PMID- 27716441 TI - Shock wave-induced ATP release from osteosarcoma U2OS cells promotes cellular uptake and cytotoxicity of methotrexate. AB - BACKGROUND: Osteosarcoma is the most prevalent primary malignant bone tumor, but treatment is difficult and prognosis remains poor. Recently, large-dose chemotherapy has been shown to improve outcome but this approach can cause many side effects. Minimizing the dose of chemotherapeutic drugs and optimizing their curative effects is a current goal in the management of osteosarcoma patients. METHODS: In our study, trypan blue dye exclusion assay was performed to investigate the optimal conditions for the sensitization of osteosarcoma U2OS cells. Cellular uptake of the fluorophores Lucifer Yellow CH dilithium salt and Calcein was measured by qualitative and quantitative methods. Human MTX ELISA Kit and MTT assay were used to assess the outcome for osteosarcoma U2OS cells in the present of shock wave and methotrexate. To explore the mechanism, P2X7 receptor in U2OS cells was detected by immunofluorescence and the extracellular ATP levels was detected by ATP assay kit. All data were analyzed using SPSS17.0 statistical software. Comparisons were made with t test between two groups. RESULTS: Treatment of human osteosarcoma U2OS cells with up to 450 shock wave pulses at 7 kV or up to 200 shock wave pulses at 14 kV had little effect on cell viability. However, this shock wave treatment significantly promoted the uptake of Calcein and Lucifer Yellow CH by osteosarcoma U2OS cells. Importantly, shock wave treatment also significantly enhanced the uptake of the chemotherapy drug methotrexate and increased the rate of methotrexate-induced apoptosis. We found that shock wave treatment increased the extracellular concentration of ATP and that KN62, an inhibitor of P2X7 receptor reduced the capacity methotrexate induced apoptosis. CONCLUSIONS: Our results suggest that shock wave treatment promotes methotrexate-induced apoptosis by altering cell membrane permeability in a P2X7 receptor-dependent manner. Shock wave treatment may thus represent a possible adjuvant therapy for osteosarcoma. PMID- 27716440 TI - A field tool for prediction of body fat in Sri Lankan women: skinfold thickness equation. AB - BACKGROUND: Valid skinfold thickness (SFT) equations for the prediction of body fat are currently unavailable for South Asian women and would be a potentially robust field tool. Our aim was to assess the validity of existing SFT equations against deuterium (2H2O) dilution and, if invalid, to develop and validate an SFT equation for % fat mass (%FM) in Sri Lankan women. METHODS: H2O dilution was used with Fourier transform infrared (FTIR) spectroscopy as the criterion method for the assessment of %FM in urban Sri Lankan women (30-45 years). This data was used to assess the validity of available SFT equations and to generate and validate a new SFT equation for the prediction of %FM against the criterion method. Women (n = 164) were divided into validation and cross-validation groups for the development and validation of the new equation. The level of agreement between the %FM calculated by the final derived prediction equation and the %FM obtained by 2H2O dilution was assessed using Pearson's correlation coefficient (R) and Bland Altman plots. Student's t test was used to assess over- or underestimation, and significance was set at p < 0.05. RESULTS: Existing equations significantly (p < 0.001) underestimated %FM compared with the 2H2O dilution method. The final equation obtained was %FM = 19.621 + (0.237*weight) + (0.259*triceps). When compared with 2H2O dilution, %FM by the equation was not significantly different. There was a significant (p < 0.001) correlation between %FM by the reference method and %FM by the equation. The limit of agreement by Bland Altman plot was narrow with a small mean positive bias. CONCLUSIONS: Existing SFT equations were not applicable to this population. The new equation derived was valid. We report a new SFT equation to predict %FM in women of South Asian ancestry suitable for field use. PMID- 27716442 TI - Treatment of unilateral spatial neglect after stroke using transcranial direct current stimulation (ELETRON trial): study protocol for a randomized controlled trial. AB - BACKGROUND: Unilateral spatial neglect (USN) is characterized by the inability to report or respond to people or objects that are presented in the spatial hemisphere that is contralateral to the lesioned hemisphere of the brain. USN has been associated with poor functional outcomes and long stays in hospitals and rehabilitation centers. Noninvasive brain stimulation, such as transcranial direct current stimulation (tDCS), has been used in people who have been affected by USN after stroke. The effects of such treatment could provide new insights for health professionals and policy-makers. The aim of this study will be to evaluate the effectiveness and safety of tDCS for USN after stroke. METHODS: A prospective randomized controlled trial with two parallel groups will be conducted, which will aim to recruit 60 patients with USN after ischemic or hemorrhagic stroke. Participants will be randomly placed into the following four treatment groups: (1) anodal tDCS over the right parietal lobe (n = 15), (2) cathodal tDCS over the left parietal lobe (n = 15), (3) a sham group of anodal tDCS over the right parietal lobe (n = 15), and (4) a sham group of cathodal tDCS over the left parietal lobe (n = 15). Blinded assessors will conduct two baseline assessments and one post-intervention assessment. The primary outcome measure will be the level of USN as assessed by the conventional Behavioral Inattention Tasks and the Catherine Bergego Scale. Secondary measures will include neurological capacity (based on the Scandinavian Stroke Scale), functional capacity (based on the Functional Independence Measure and Modified Rankin Scale), autonomy (based on the Barthel Index), and quality of life (based on the EuroQol-5D). Group allocation will be concealed, and all analyses will be based on an intention-to treat principle. DISCUSSION: This study will explore the effects of more than 15 sessions of tDCS on the level of USN, functional capacity, autonomy, and quality of life in patients with USN after stroke. This proposed study has the potential to identify a new, evidence-based intervention that can enhance perception and independent living in patients with USN after stroke.

PMID- 27716443 TI - A discrete cluster of urinary biomarkers discriminates between active systemic lupus erythematosus patients with and without glomerulonephritis. AB - BACKGROUND: Management of lupus nephritis (LN) would be greatly aided by the discovery of biomarkers that accurately reflect changes in disease activity. Here, we used a proteomics approach to identify potential urinary biomarkers associated with LN. METHODS: Urine was obtained from 60 LN patients with paired renal biopsies, 25 active non-LN SLE patients, and 24 healthy controls. Using Luminex, 128 analytes were quantified and normalized to urinary creatinine levels. Data were analyzed by linear modeling and non-parametric statistics, with corrections for multiple comparisons. A second cohort of 33 active LN, 16 active non-LN, and 30 remission LN SLE patients was used to validate the results. RESULTS: Forty-four analytes were identified that were significantly increased in active LN as compared to active non-LN. This included a number of unique proteins (e.g., TIMP-1, PAI-1, PF4, vWF, and IL-15) as well as known candidate LN biomarkers (e.g., adiponectin, sVCAM-1, and IL-6), that differed markedly (>4 fold) between active LN and non-LN, all of which were confirmed in the validation cohort and normalized in remission LN patients. These proteins demonstrated an enhanced ability to discriminate between active LN and non-LN patients over several previously reported biomarkers. Ten proteins were found to significantly correlate with the activity score on renal biopsy, eight of which strongly discriminated between active proliferative and non-proliferative/chronic renal lesions. CONCLUSIONS: A number of promising urinary biomarkers that correlate with the presence of active renal disease and/or renal biopsy changes were identified and appear to outperform many of the existing proposed biomarkers. PMID- 27716444 TI - Survival after heart transplantation for non-metastatic primary cardiac sarcoma. AB - BACKGROUND: Heart transplantation is an uncommon treatment for unresectable and non-metastatic primary cardiac sarcomas, and the role of it is unclear. This study aims to offer a survival analysis of it. METHODS: This study consists of 6 patients from our institution and 40 patients identified in a literature search who underwent heart transplantation for non-metastatic primary cardiac sarcomas. Seven patients with unresectable cardiac angiosarcoma who received palliative therapies at our institution were included for comparison. All the clinicopathologic data were collected, retrospectively reviewed and statistically analyzed. RESULTS: Among the 46 patients receiving heart transplantation for primary cardiac sarcomas, the overall median survival was 16 months (2-112 months). The most common histologic type receiving heart transplantation was angiosarcoma. Its median survival time after heart transplantation (n = 14) was much less than that of other histologic types (n = 31) (9 vs 36 months; P = 0.002), which means it was not different from the median survival of 8 months for patients (n = 7) receiving palliative therapies (P = 0.768). The patients with grade 2 cardiac sarcomas (n = 5) survived much longer after heart transplantations than patients with grade 3 tumors (n = 15) (mean survival: 85 vs 18 months; P = 0.006). Neoadjuvant or adjuvant chemotherapy didn't provide survival benefits after heart transplantation. CONCLUSIONS: Cardiac angiosarcoma seems to be not the proper indication of heart transplantation. The role of heart transplantation in other histologic subtypes still remains undefined. Lower grade and less aggressive histologic subtypes benefit more from heart transplantation. PMID- 27716445 TI - Suppression of vagal cardiac modulation by blue light in healthy subjects. AB - BACKGROUND: In the contemporary life environments, our body is increasingly exposed to various sources of colored light, which may affect our physiological functions as non-image-forming effects. We examined the impacts of colored lights on the autonomic functions by the analysis of heart rate variability (HRV). METHODS: A lighting device consisting of four organic light-emitting diode (OLED) modules (55 * 55 mm2) with adjustable red-green-blue color was secured 24 cm above the eyes of subject lying supine in a light-shielded laboratory. Following a 15-min supine rest, electrocardiogram and respiration were measured continuously during 3-min darkness, 6-min colored OLED illumination, and 3-min darkness under paced breathing (15 breath/min). The measurements were repeated at a 45-min interval for red, green, and blue lights with melanopsin-stimulating photon flux density (MSPFD) of 0.00, 0.10, and 0.20 MUmol/m2/s, respectively, in 12 healthy subjects (23 +/- 2 years, two females). Additionally, the effects of blue lights with 0.20, 0.10, and 0.04 MUmol/m2/s MSPFD were examined in four healthy subjects (25-39 years, two females). HRV was analyzed for low-frequency (LF, 0.04-0.15 Hz) and high-frequency (HF, 0.20-0.30 Hz) power and LF-to-HF ratio (LF/HF). RESULTS: Compared to darkness before lighting, HF power decreased (P < 0.001) and LF/HF increased (P = 0.024) during lighting on average of all color lights, whereas HF power showed a greater decrease with blue light than with red and green lights (P < 0.05 for both). The decrease in HF power lasted even during darkness after lighting (P < 0.001). HF power decreased with blue light with 0.20 MUmol/m2/s MSPFD (P < 0.001) but not with that with 0.10 or 0.04 MUmol/m2/s (P = 0.1 and 0.9, respectively). CONCLUSIONS: Vagal cardiac modulation is suppressed by OLED blue light in healthy subjects most likely through melanopsin-dependent non-image-forming effect. PMID- 27716446 TI - Gait training assisted by multi-channel functional electrical stimulation early after stroke: study protocol for a randomized controlled trial. AB - BACKGROUND: Many stroke survivors suffer from paresis of lower limb muscles, resulting in compensatory gait patterns characterised by asymmetries in spatial and temporal parameters and reduced walking capacity. Functional electrical stimulation has been used to improve walking capacity, but evidence is mostly limited to the orthotic effects of peroneal functional electrical stimulation in the chronic phase after stroke. The aim of this study is to investigate the therapeutic effects of up to 10 weeks of multi-channel functional electrical stimulation (MFES)-assisted gait training on the restoration of spatiotemporal gait symmetry and walking capacity in subacute stroke patients. METHODS: In a proof-of-principle study with a randomised controlled design, 40 adult patients with walking deficits who are admitted for inpatient rehabilitation within 31 days since the onset of stroke are randomised to either MFES-assisted gait training or conventional gait training. Gait training is delivered in 30-minute sessions each workday for up to 10 weeks. The step length symmetry ratio is the primary outcome. Blinded assessors conduct outcome assessments at baseline, every 2 weeks during the intervention period, immediately post intervention and at 3 month follow-up. DISCUSSION: This study aims to provide preliminary evidence for the feasibility and effectiveness of MFES-assisted gait rehabilitation early after stroke. Results will inform the design of a larger multi-centre trial. TRIAL REGISTRATION: This trial is registered at the Netherlands Trial Register (number NTR4762 , registered 28 August 2014). PMID- 27716447 TI - Dramatic reduction of mortality in pneumococcal meningitis. AB - BACKGROUND: Acute bacterial meningitis is still a life threatening disease. METHODS: We performed a retrospective observational study on the clinical characteristics of consecutively admitted patients with acute pneumococcal meningitis in a single tertiary care center in central Europe (from 2003 until 2015). Data were compared with a previously published historical group of 87 patients treated for pneumococcal meningitis at the same hospital (from 1984 until 2002). RESULTS: Fifty-five consecutive patients with microbiologically proven pneumococcal meningitis were included. Most striking, mortality was down to 5.5 %, which was significantly lower than in the historical group where 24.1 % of the patients did not survive. Intracranial complications during the course of the disease were common and affected half of the patients. Unlike in the historic group, most of the intracranial complications (except ischemic stroke) were no longer associated with a low Glasgow Outcome Score at discharge. CONCLUSION: The drastic reduction of mortality proves there have been important advances in the treatment of pneumococcal meningitis. Nevertheless, the fact that only 44.2 % of survivors had a full recovery indicates that the search for new adjunctive treatment options must be ongoing. PMID- 27716448 TI - The complement system is activated in synovial fluid from subjects with knee injury and from patients with osteoarthritis. AB - BACKGROUND: The complement system is suggested to be involved in the pathogenesis of osteoarthritis (OA), and proinflammatory cytokines may play a role in OA development by inducing proteases. The association between complement factors, cytokines and OA has not been investigated. The aim of the present study was to explore the involvement of the complement system after knee trauma and in OA. METHODS: C4d, C3bBbP and soluble terminal complement complex (sTCC) resulting from complement activation were immunoassayed in synovial fluid from subjects with healthy knees (reference), OA, rheumatoid arthritis (RA; positive control), pyrophosphate arthritis (PPA; positive control) and knee injury; other biomarkers were previously assessed. Magnetic resonance imaging was used to assess joint injuries. RESULTS: Compared with levels in the reference group, the median concentrations of C4d, C3bBbP and sTCC in the OA, RA, PPA and knee injury groups were 2- to 34-fold increased (p < 0.001 to p = 0.044). For the knee injury group, the median concentrations of C4d, C3bBbP and sTCC were 5- to 12-fold increased (p < 0.001) at the day of injury; after 3-12 weeks, C3bBbP and sTCC concentrations were similar to reference levels; and C4d was still increased several years after injury. In the 0-12 weeks period after injury, the concentrations of C4d, C3bBbP and sTCC correlated positively with levels of interleukin (IL)-1beta, IL-6 and tumour necrosis factor alpha (r s range 0.232-0.547); none of the measured complement factors correlated with proteolytic fragments of aggrecan or cartilage oligomeric matrix protein. Knees with osteochondral fracture, with or without disrupted cortical bone, had higher concentrations of C4d (p = 0.014, p = 0.004) and sTCC (p = 0.004, p < 0.001) compared with knees without fractures. CONCLUSIONS: The complement system is activated in OA and after knee injury. Following knee injury, this activation is instant and associated with inflammation as well as with the presence of osteochondral fractures. PMID- 27716449 TI - Efficacy of intranasal LaAg vaccine against Leishmania amazonensis infection in partially resistant C57Bl/6 mice. AB - BACKGROUND: We have previously demonstrated that intranasal vaccination of highly susceptible BALB/c mice with whole Leishmania amazonensis antigens (LaAg) leads to protection against murine cutaneous leishmaniasis. Here, we evaluate the response of partially resistant C57BL/6 mice to vaccination as a more representative experimental model of human cutaneous leishmaniasis. METHODS: C57BL/6 mice from different animal facilities were infected with L. amazonensis (Josefa strain) to establish the profile of infection. Intranasal vaccination was performed before the infection challenge with two doses of 10 MUg of LaAg alone or associated with the adjuvant ADDAVAX(r) by instillation in the nostrils. The lesion progression was measured with a dial caliper and the parasite load by limited dilution assay in the acute and chronic phases of infection. Cytokines were quantified by ELISA in the homogenates of infected footpads. RESULTS: C57BL/6 mice from different animal facilities presented the same L. amazonensis infection profile, displaying a progressive acute phase followed by a controlled chronic phase. Parasites cultured in M199 and Schneider's media were equally infective. Intranasal vaccination with LaAg led to milder acute and chronic phases of the disease. The mechanism of protection was associated with increased production of IFN-gamma in the infected tissue as measured in the acute phase. Association with the ADDAVAX(r) adjuvant did not improve the efficacy of intranasal LaAg vaccination. Rather, ADDAVAX(r) reduced vaccination efficacy. CONCLUSION: This study demonstrates that the efficacy of adjuvant-free intranasal vaccination with LaAg is extendable to the more resistant C57Bl/6 mouse model of infection with L. amazonensis, and is thus not exclusive to the susceptible BALB/c model. These results imply that mucosal immunomodulation by LaAg leads to peripheral protection irrespective of the genetic background of the host. PMID- 27716450 TI - Picodroplet partitioned whole genome amplification of low biomass samples preserves genomic diversity for metagenomic analysis. AB - BACKGROUND: Whole genome amplification (WGA) is a challenging, key step in metagenomic studies of samples containing minute amounts of DNA, such as samples from low biomass environments. It is well known that multiple displacement amplification (MDA), the most commonly used WGA method for microbial samples, skews the genomic representation in the sample. We have combined MDA with droplet microfluidics to perform the reaction in a homogeneous emulsion. Each droplet in this emulsion can be considered an individual reaction chamber, allowing partitioning of the MDA reaction into millions of parallel reactions with only one or very few template molecules per droplet. RESULTS: As a proof-of-concept, we amplified genomic DNA from a synthetic metagenome by MDA either in one bulk reaction or in emulsion and found that after sequencing, the species distribution was better preserved and the coverage depth was more evenly distributed across the genomes when the MDA reaction had been performed in emulsion. CONCLUSIONS: Partitioning MDA reactions into millions of reactions by droplet microfluidics is a straightforward way to improve the uniformity of MDA reactions for amplifying complex samples with limited amounts of DNA. PMID- 27716451 TI - Surgical treatment of a broken neuroplasty catheter in the epidural space: a case report. AB - BACKGROUND: Percutaneous epidural neuroplasty with a Racz catheter is widely used to treat radicular pain caused by spinal stenosis or a herniated intervertebral disc. The breakage or shearing of an epidural catheter, particularly a percutaneous epidural neuroplasty catheter, is reported as a rare complication. There has been a controversy over whether surgical removal of a shorn epidural catheter is needed. Until now, only three cases related to sheared Racz neuroplasty catheters have been reported. We report a case of a neuroplasty catheter which completely broke when it was inserted into the epidural space, and compressed root symptoms were exacerbated by the broken catheter. CASE PRESENTATION: A 68-year-old Asian man with leg pain and lower back pain caused by lumbar vertebral body 4 to lumbar vertebral body 5 intervertebral disc herniation and stenosis underwent percutaneous epidural neuroplasty. During the procedure, the epidural neuroplasty catheter was trapped in the left foraminal portion and broke. Our patient complained of left-side leg pain and numbness. Surgery performed to remove the broken catheter led to complete resolution of his leg pain and numbness. CONCLUSIONS: We report a rare case of catheter breakage occurring during epidural neuroplasty. We suggest surgical removal because the implanted catheter can aggravate a patient's symptoms and lead to the development of neurologic deficits due to infection, fibrosis, or mechanical neural irritation. PMID- 27716452 TI - Comparison of computed tomography features between follicular neoplasm and nodular hyperplasia. AB - BACKGROUND: To date, appropriate management for Bethesda IV thyroid nodules is controversial, and no specific features of follicular neoplasm and nodular hyperplasia on ultrasonography, computed tomography (CT), or other imaging modalities have been reported. This study aimed to compare CT features of follicular neoplasm and nodular hyperplasia and to determine the specific CT features that could be used to distinguish follicular neoplasm from nodular hyperplasia. METHODS: In 122 patients who underwent preoperative CT of the neck and thyroid surgery, 59 follicular neoplasms and 65 nodular hyperplasias were included. In each case, non-enhanced and contrast-enhanced CT images were obtained, and a single radiologist retrospectively analyzed CT images, including degree and pattern of attenuation, nodular configuration, margin, shape, pattern of calcification, degree and pattern of nodular enhancement, and CT halo sign. A univariate and multivariate logistic regression analyses were used to evaluate the predictive power of each variable and CT features with a high predictive power, respectively. RESULTS: According to the univariate analysis, iso attenuation, intraglandular configuration, smooth margin, ovoid shape, decreased enhancement, and absence of CT halo sign were more frequently observed in nodular hyperplasia (p < 0.05), whereas low attenuation, expansile configuration, lobulated margin, taller-than-wide shape, increased enhancement, and presence of computed tomography halo sign were more frequently observed in follicular neoplasm (p < 0.05). Multivariate analysis revealed significant differences in configuration (OR: 2.73, 1.13-6.57), degree of enhancement (OR: 2.14, 1.21-3.78), and presence of CT halo sign (OR: 7.97, 2.74-23.37) between follicular neoplasm and nodular hyperplasia (p < 0.05). CONCLUSIONS: Neck CT may be helpful for distinguishing follicular neoplasm from nodular hyperplasia. TRIAL REGISTRATION: Rretrospectively registered. PMID- 27716453 TI - Editorial.

AB - Rheumatoid arthritis (RA) is an autoimmune disease characterised by chronic synovial inflammation leading to joint destruction and bone erosions. Although the pathogenic mechanisms underlying the disease are not fully elucidated, it is known that genetic susceptibility and environmental factors trigger an abnormal autoimmune response. Potentially, any organ and tissue could be affected by RA and the increased cardiovascular (CV) risk represents the major complication responsible for a worse prognosis. In this setting, the shared pathogenic mechanisms between RA pathogenesis and accelerated atherosclerosis further strengthen the rationale for a treat-to-target strategy with synthetic and biologic disease modifying anti-rheumatic drugs. The aim of this review is to provide the novel insights, regarding the pathogenesis of RA, published over the last year. PMID- 27716459 TI - Study of the bone behavior around a neck preserving short stem implant: bone densitometric analysis over a span of two years. AB - PURPOSE: Study the bone mineral density (BMD) changes and the remodelling process after implantation of a neck preserving short stem implant over a period of two years. METHODS: Using specific patients' selection criterion, a prospective study was done including 26 patients. All were operated upon by a single surgeon using the MiniHipTM, (Corin, Cirencester, UK). Mean age was 42.5 years. Clinical and radiological evaluation was done. Periprosthetic bone density was measured by DEXA. First scan was obtained within 10 days after surgery and served as a baseline for comparison. RESULTS: The mean pre-operative Harris Hip score of 37.8 increased to 95.1 points two years post-operatively. BMD in the overall periprosthetic area showed a significant reduction during the first three months. Restoration to the original levels was reached in all zones except the most proximal zones at one year. A net increase was detected (+3%) after two years. CONCLUSION: The neck preserving MiniHip short stem implant has proven to be a bone-friendly design. Significant bone remodeling process continues after the first year. Although bone resorption in the greater trochanteric region is still a problem, however, it has proven that the BMD in all the other periprosthetic regions including the calcar and the lesser trochanteric regions, are subjected to bone formation process over a period of two years.

AB - INTRODUCTION: Minimal important difference (MID) score is an important measure for surgical clinical research and impacts on treatment decisions. Our approach considered patient satisfaction as the relevant anchor criteria. The aims of this study were: determine after surgery MID for three relevant questionnaires: Disabilities of the Arm, Shoulder and Hand (DASH), Michigan Hand Questionnaire (MHQ), and Short Form 12 (SF-12); and assess the correlation between these scores and patient reported satisfaction. METHODS: Adult patients where surgery was indicated for any hand/wrist conditions. Study was conducted in a teaching hospital, Sao Paulo, Brazil. Participants responded to DASH, SF-12, MHQ, and a Likert satisfaction scale before and three months after a procedure. Satisfaction was considered as the anchor for determining MID after a procedure. The correlation between satisfaction and the instruments were measured. Two statistical approaches were utilized for determining MIDs and were used for consistency and generalizability purposes. For MID determination, receiver operating curves were utilized and MID cut-offs were followed by sensitivity and specificity measures. RESULTS: Fifty patients were included with no follow-up losses. MID for DASH was 18.8 and 15.4. MID for MHQ was 14.7 for both approaches. Data from SF-12 was not reliable after statistical analyses and demonstrated poor correlation with patient satisfaction. MID for DASH and MHQ were found and demonstrated larger standards than literature-reported patients when surgery was not the main intervention. DASH and MHQ had moderate correlation with patient reported satisfaction. SF-12 MID was not reliable and had poor correlation to patient satisfaction. These data suggests that ambulatory hand surgery patients may have greater expectations regarding improvement than other patients.

AB - INTRODUCTION: The shoulder arthroplasty brings satisfaction to patients in terms of quality of life and indolence. However whether anatomic implant or reverse, it does not escape from the loosening of the glenoid component. Moreover, optimal implantation is required to ensure the functional outcome without shortening of the arm. The purpose of this study is obtain CT scan evaluation of the glenoid bone stock in order to optimize glenoid component implantation and obtain a reference to determine optimal humeral component placement in case of humeral proximal fracture. MATERIALS AND METHODS: Between 2010 and 2011 we have analyzed 200 intact shoulder's CT. We measured maximal and minimal width in the transverse plane of the glenoid, the distance from the pectoralis major (PM) tendon to the humeral head, the greater tubercle, change of curvature and the anatomical neck. RESULTS: Mean maximum width was 27.4 +/- 3.4 mm and mean minimum width was 15.5 +/- 2.8 mm. Distances between upper edge of PM tendon to: humeral head, greater tubercle, change of curvature and anatomical neck were respectively: 67.6 +/- 9.98 mm, 57.8 +/- 10.3 mm, 28.7 +/- 9 mm, and 34.2 +/- 9.7 mm. CONCLUSION: Our study has produced an assessment of glenoid bone stock for optimal positioning of the glenoid implant but also to obtain a reference to determine the ideal location of the humeral component in the case of proximal humerus fracture.

AB - Surface charge at solid-electrolyte interface is generally coupled with the local electrolyte properties (ionic concentration, pH, etc.), and therefore not as assumed homogeneous on the solid surfaces in the previous studies. The inhomogeneous charge brings huge challenges in predictions of electro-osmotic transport and has never been well studied. In this work, we first propose a classification of electro-osmosis based on a dimensionless number which is the ratio of the Debye length to the characteristic pore size. In the limit of thin electrical double layer, we establish a pore-scale numerical model for inhomogeneously charged electro-osmosis including four ions: Na+,Cl-,H+ and OH-. Based on reconstructed porous media, we simulate the electro-osmosis with inhomogeneous charge using lattice Boltzmann method. The nonlinear response of electro-osmotic velocity to applied electrical field and the reverse flow have been observed and analyzed.

AB - The hydrothermal method was explored to prepare SnO2 nanorods (SnO2 NRs) with the special faces of (110) and (101) on the surface of Fe2O3 nanotubes (Fe2O3 NTs). According to the SEM and XRD results, the formation process of the hierarchically assembled SnO2 NRs was deduced. The SnO2 NRs/Fe2O3 NTs catalyst that had reached for 120 mins behaved the best photoelectrocatalytic properties. From the view of photocatalytic reduction, the conduction band (-0.75eV vs NHE) is negative enough to drive CO2 reduction, and the valence band (1.82eV) is positive enough to oxidize H2O to generate proton, and then the proton is used for CO2 reduction. From the electrocatalytic reduction point, the net CO2 reduction current density of the composite is 7.48 times that of Fe2O3 NTs at -1.1V, indicating that the electrocatalytic performance of Fe2O3 NTs is greatly enhanced by the introduction of 6-fold branched SnO2 NRs. The predominant reduction product is analyzed by GC was methanol. Herein, two synergistic effects are proved according to the methanol yields, one is the synergistic effect of the photocatalytic and electrocatalytic reduction, the other is the synergistic effect between SnO2 NRs and Fe2O3 NTs. The results indicated that the composite catalyst behaves excellent photoelectrocatalytic activity for CO2 reduction. PMID- 27716464 TI - Differential methylation of the circular DNA in geminiviral minichromosomes. AB - Geminiviral minichromosomes were purified to explore epigenetic modifications. The levels of methylation in their covalently closed circular DNA were examined with the help of methylation-dependent restriction (MdR). DNA with 12 superhelical turns was preferentially modified, indicating minichromosomes with 12 nucleosomes leaving an open gap. MdR digestion yielded a specific product of genomic length, which was cloned and Sanger-sequenced, or amplified following ligation-mediated rolling circle amplification and deep-sequenced (circomics). The conventional approach revealed a single cleavage product indicating specific methylations at the borders of the common region. The circomics approach identified considerably more MdR sites in a preferential distance to each other of ~200 nts, which is the DNA length in a nucleosome. They accumulated in regions of nucleosome-free gaps, but scattered also along the genomic components. These results may hint at a function in specific gene regulation, as well as in virus resistance. PMID- 27716465 TI - Evasion of early innate immune response by 2'-O-methylation of dengue genomic RNA. AB - Dengue virus (DENV) is the most prevalent mosquito-borne virus pathogen in humans. There is currently no antiviral therapeutic or widely available vaccine against dengue infection. The DENV RNA genome is methylated on its 5' cap by its NS5 protein. DENV bearing a single E216A point mutation in NS5 loses 2'-O methylation of its genome. While this mutant DENV is highly attenuated and immunogenic, the mechanism of this attenuation has not been elucidated. In this study, we find that replication of this mutant DENV is attenuated very early during infection. This early attenuation is not dependent on a functional type I interferon response and coincides with early activation of the innate immune response. Taken together, our data suggest that 2'-O-methylation of DENV genomic RNA is important for evasion of the host immune response during the very early stages of infection as the virus seeks to establish infection. PMID- 27716466 TI - Ptaquiloside from bracken in stream water at base flow and during storm events. AB - The bracken fern (Pteridium spp.) densely populates both open and woodland vegetation types around the globe. Bracken is toxic to livestock when consumed, and a group of potent illudane-type carcinogens have been identified, of which the compound ptaquiloside (PTA) is the most abundant. The highly water soluble PTA has been shown to be leachable from bracken fronds, and present in the soil and water below bracken stands. This has raised concerns over whether the compound might pose a risk to drinking water sources. We investigated PTA concentrations in a small stream draining a bracken-infested catchment at base flow and in response to storm events during a growth season, and included sampling of the bracken canopy throughfall. Streams in other bracken-dominated areas were also sampled at base flow for comparison, and a controlled pulse experiment was conducted in the field to study the in-stream dynamics of PTA. Ptaquiloside concentrations in the stream never exceeded 61 ng L-1 in the base flow samples, but peaked at 2.2 MUg L-1 during the studied storm events. The mass of PTA in the stream, per storm event, was 7.5-93 mg from this catchment. A clear temporal connection was observed between rainfall and PTA concentration in the stream, with a reproducible time lag of approx. 1 h from onset of rain to elevated concentrations, and returning rather quickly (about 2 h) to base flow concentration levels. The concentration of PTA behaved similar to an inert tracer (Cl-) in the pulse experiment over a relative short time scale (minutes-hours) reflecting no PTA sorption, and dispersion and dilution considerably lowered the observed PTA concentrations downstream. Bracken throughfall revealed a potent and lasting source of PTA during rainfall, with concentrations up to 169 MUg L-1, that did not decrease over the course of the event. In the stream, the throughfall contribution to PTA cannot be separated from a possible below-ground input from litter, rhizomes and soil. Catchment-specific factors such as the soil pH, topography, hydrology, and bracken coverage will evidently affect the level of PTA observed in the receiving stream, as well as the distance from bracken, but time since precipitation seems most important. Studying PTA loads and transport in surface streams fed by bracken-infested catchments, simply taking occasional grab samples will not capture the precipitation-linked pulses. The place and time of sampling governs the findings, and including event-based sampling is essential to provide a more complete picture of PTA loads to surface water.

AB - Electrochemical degradation of aqueous solutions containing antibiotic amoxicillin (AMX) has been extensively studied in an undivided electrolytic cell using a sub-stoichiometric titanium oxide (Ti4O7) anode, elaborated by plasma deposition. Oxidative degradation of AMX by hydroxyl radicals was assessed as a function of applied current and was found to follow pseudo-first order kinetics. The use of carbon-felt cathode enhanced oxidation capacity of the process due to the generation of H2O2. Comparative studies at low current intensity using dimensional stable anode (DSA) and Pt anodes led to the lower mineralization efficiencies compared to Ti4O7 anode: 36 and 41% TOC removal for DSA and Pt respectively compared to 69% for Ti4O7 anode. Besides, the use of boron doped diamond (BDD) anode under similar operating conditions allowed reaching higher mineralization (94%) efficiency. Although Ti4O7 anode provides a lesser mineralization rate compared to BDD, it exhibits better performance compared to the classical anodes Pt and DSA and can constitutes an alternative to BDD anode for a cost effective electro-oxidation process. Moreover several aromatic and aliphatic oxidation reaction intermediates and inorganic end-products were identified and a plausible mineralization pathway of AMX involving these intermediates was proposed. PMID- 27716468 TI - Potential microbial hazards from graywater reuse and associated matrices: A review. AB - Millions of decentralized graywater-reuse systems are operating worldwide. This water is directly accessible to household inhabitants, raising environmental and public health concerns. Graywater may contain a variety of harmful organisms, the types and numbers of which vary with source-type, storage time, and background levels of infection in the community source. In this review, we find that most studies indicate high amounts of microbial pathogens in raw graywater and therefore treatment and disinfection are recommended to lower possible health risks. Where these recommendations have been followed, epidemiological and quantitative microbial risk-assessment studies have found negligible health risks of bacterial pathogens in treated graywater. Chlorine is currently suggested as the most cost-effective disinfection agent for inactivating graywater bacterial pathogens and preventing regrowth. Various studies demonstrate that the introduction and diversity of pathogenic bacteria in the soil via irrigation can be affected by several factors, but treated graywater may not be a major contributor of bacterial contamination or antibiotic resistance. However, an accurate assessment of the infectious capabilities, exposure pathways, and resistance of specific pathogens, particularly viruses and antibiotic-resistant bacteria found in treated graywater after disinfection, as well as in the graywater piping, irrigated soils, plants, and associated aerosols is largely lacking in the literature. In addition, research shows that fecal bacterial indicators might not reliably indicate the presence or quantities of pathogens in graywater and thus, the indicator standard for graywater contamination should be revised. PMID- 27716469 TI - Characterization of nonpathogenic Listeria species isolated from food and food processing environment. AB - A total of 127 Listeria isolates from food and food processing environments, including 75 L. innocua, 49 L. welshimeri, 2 L. seeligeri and 1L. grayi were tested for susceptibility to eight antimicrobials, benzalkonium chloride (BC), cadmium and arsenic. The isolates were also screened for the presence of extrachromosomal genetic elements - plasmids, and their restriction pattern types were determined. All strains were susceptible to ampicillin, ciprofloxacin, erythromycin, gentamicin, rifampicin, trimethoprim and vancomycin. Two of the L. innocua isolates showed resistance to tetracycline and minocycline. The resistance was determined by the presence of chromosomal localization of tet(M) gene, which was not integrated in the transposon Tn916-Tn1545 family. Of analyzed isolates, 18.11% and 55.91% isolates were resistant to BC and cadmium, respectively, but all were susceptible to arsenic. Resistance to BC was correlated with resistance to cadmium - all BC resistant isolates were also resistant to cadmium. On the other hand, 67.61% of cadmium-resistant isolates were susceptible to BC, suggesting that cadmium and BC resistance were not always concurrent in Listeria species. 48.03% of isolates contained plasmids. The size of most of the identified replicons was in the range of 50-90kb. All plasmids were classified into 12 groups with identical restriction pattern (I-XII). Interestingly, plasmids belonging to the same group were determined in isolates of the same species. Only in one case, plasmids with I-type profile were identified in L. innocua and L. welshimeri. There was an association between resistance to BC and plasmid DNA presence: all resistant isolates carried a plasmid. A correlation between resistance to cadmium and plasmid carriage was also observed in L. innocua and L. seeligeri isolates, but among resistant L. welshimeri, 23.08% of isolates did not have plasmids. This may suggest that resistance is associated with determinants located within the chromosome. To elucidate the adaptation strategies and ecology of Listeria spp., it is important to have a better understanding of its resistance to antimicrobials and environmental toxicants such as heavy metals and disinfectants. PMID- 27716470 TI - Applicability of the EN ISO 11290-1 standard method for Listeria monocytogenes detection in presence of new Listeria species. AB - During the past six years, new species of the genus Listeria have been isolated from foods and other environmental niches worldwide. The Standard method EN ISO 11290-1 that is currently under revision will include in its scope all Listeria species in addition to L. monocytogenes. The objective of this project was to evaluate the ability of the Standard EN ISO 11290-1 method to detect and identify the newly discovered Listeria spp., and to assess potential over-growth effects of the new species in mixed cultures with L. monocytogenes during each step of the enrichment process. This objective was addressed by the generation of necessary data on the behavior of the new species during the pre-enrichment and the enrichment steps of the reference method as well as data on their phenotypic characteristics on rich and selective media used for isolation and identification. Most of the new Listeria species developed well on selective agar media for Listeria, however the recovery of some species was difficult due to poor growth in Half Fraser and Fraser broth. Good results (consistently positive) were obtained for confirmation at the genus level via the catalase test, the Gram test and the blueish appearance test on non-selective medium, but not with the VP test, as most of the new species yielded a negative result. In the light of results obtained in co-culture experiments and inhibition tests, and considering the growth rates in Half Fraser and Fraser broths, the new species do not seem to interfere with the detection of L. monocytogenes. PMID- 27716471 TI - Induction and stability of oxidative stress adaptation in Listeria monocytogenes EGD (Bug600) and F1057 in sublethal concentrations of H2O2 and NaOH. AB - Food processing and food handling environments may contain residual levels of sanitizers or cleaners which may trigger oxidative stress adaptation in Listeria monocytogenes. The aim of this study was to determine the induction and stability of oxidative stress adaptation in L. monocytogenes EGD (Bug600) (serotype 1/2a) and F1057 (serotype 4b) at different concentrations and times of sublethal oxidative stress induced by H2O2 or sublethal alkali stress induced by NaOH at 37 degrees C. Both L. monocytogenes Bug600 and F1057 strains showed significantly higher survival in lethal oxidative stress (1000ppm H2O2) after pre-exposure to 50ppm H2O2 for 30min compared to control cells (no pre-exposure to H2O2). When the cells were pre-exposed to sublethal alkali stress by NaOH, the oxidative stress adaptation was induced within 5min in L. monocytogenes. The survival of both L. monocytogenes strains was increased by 2 to 4.5 logs in lethal oxidative stress when the cells were pre-exposed to sublethal alkali stress at pH9 from 5 to 120min by NaOH compared to control cells (no pre-exposure to sublethal alkali pH). Two other alkali reagents tested (KOH and NH4OH) also induced oxidative stress adaptation in L. monocytogenes. For both L. monocytogenes strains, the oxidative stress adaptation induced by sublethal H2O2 was reversible in 30min and that induced by sublethal alkali stress was reversible within 60min at 37 degrees C in the absence of such sublethal stress. These findings show that sublethal oxidative or alkali stress conditions can induce oxidative stress adaptation that may increase the risk of survival of L. monocytogenes cells in lethal oxidative stress. PMID- 27716472 TI - Efficiency of a cleaning protocol for the removal of enterotoxigenic Staphylococcus aureus strains in dairy plants. AB - Staphylococci are considered a major concern in dairy plants mainly due to the intensive production flow, automation of processing plants and increased demand in the microbiological quality of dairy products. This study aimed to identify S. aureus strains isolated from three Brazilian dairy plants, evaluate the influence of time, temperature and contact surface on the bacterial adhesion process, as well as the efficiency of simulated hygiene and sanitation protocol in removing adhered cells. For genotypic analyses, the presence of icaA and icaD in strains was evaluated. Adherence assays were performed in biofilm reactor, comparing the influence of 2 temperatures (5 degrees C and 35 degrees C), 2 surfaces (stainless steel and polypropylene) and 4 contact times (3, 6, 12h and post-sanitization). To evaluate the process effectiveness in removing adhered cells, neutral detergent and sanitizing agent based on sodium hypochlorite were used in order to simulate the situation observed in one of the dairy plants analyzed. The presence of icaA and icaD genes was determined in 75.3% and 77.6% of strains, respectively; 70.6% of isolates showed both genes, whereas 17.6% showed no genes. Genes for enterotoxin production were found in all samples, relating to SEG and SEH toxins. The number of cells adhered on both surfaces was about 3 and 6 log10 CFU/cm2 at temperatures of 5 degrees C and 35 degrees C, respectively, for most situations evaluated, with significant increase over the evaluation period. In general, the temperature of 35 degrees C favored greater adherence of S. aureus. At 5 degrees C, there was a considerable number of adhered cells, but in populations significantly lower than those observed at 35 degrees C. The cleaning and sanitizing protocol was ineffective in removing adhered cells; better performance of sodium hypochlorite was observed at 5 degrees C, which should be related to lower adherence observed at this temperature. Thus, the process was not able to reduce the number of S. aureus bacteria adhered on both surfaces to safe levels under the conditions evaluated. PMID- 27716473 TI - Contribution of the activated catalase to oxidative stress resistance and gamma aminobutyric acid production in Lactobacillus brevis. AB - Lactic acid bacteria (LAB) are generally sensitive to H2O2, a compound which can paradoxically produce themselves and lead to the growth arrest and cell death. To counteract the potentially toxic effects of this compound, the gene katE encoding a heme-dependent catalase (CAT) belonging to the family of monofunctional CATs was cloned from Lactobacillus brevis CGMCC1306. The enhanced homologous CAT expression was achieved using the NICE system. L. brevis cells with overexpressed CAT showed 685-fold and 823-fold higher survival when exposed to 30mmol/L of H2O2 and long-term aerated stress (after 72h), respectively, than that of the wild type cells. Furtherly, the effects of activated CAT on GABA production in L. brevis were investigated. A GABA production level of 66.4g/L was achieved using two-step biotransformation that successively employed the growing and resting cells derived from engineering L. brevis CAT. These results demonstrated clearly that overexpression of the KatE gene in L. brevis led to a marked increased survival in oxidizing environment, and shed light on a novel feasible approach to enhance the GABA production level by improving the antioxidative properties. PMID- 27716474 TI - The impact of aging on the neural networks involved in gaze and emotional processing. AB - Normal adult aging is associated with difficulties in processing social cues to emotions such as anger and also altered motivation to focus more on positive than negative information. Gaze direction is an important modifier of the social signals conveyed by an emotion, for example, an angry face looking directly at you is considerably more threatening than an angry face looking away. In the present study we tested the hypothesis that older adults would show less neural differentiation to angry faces with direct and avert gaze compared to younger people, with the opposite prediction for happy faces. Healthy older (65-75 years; mean = 69.75) and younger (17-27 years; mean = 20.65) adults completed a functional magnetic resonance imaging experiment in which they were asked to identify happy and angry expressions displayed either with direct or averted gaze. While younger adults showed neural sensitivity to eye-gaze direction during recognition of angry expressions, older adults showed no effect of eye-gaze direction on neural response. In contrast, older adults showed sensitivity to eye gaze direction during recognition of happy expressions but younger adults did not. Additionally, brain-behavior correlations were conducted to investigate the relationships between emotion recognition and mentalizing brain network in both age groups. Younger (but not older) adults' social cognitive performance was differentially correlated with activation in 2 brain networks when looking at angry faces with direct compared to averted gaze. These novel findings provide evidence for age-related differences in the neural substrates underlying the capacity to integrate facial affect and eye-gaze cues. The results of this study suggest that age-related differences in integrating facial cues may be related to engagement of the mentalizing network, with potentially important implications for social cognitive functioning in late adulthood.

AB - Obesity is associated with chronic inflammation and is known as a major risk factor for several diseases including chronic kidney disease, diabetes, and cardiovascular diseases. Macrophages play a critical role in the development of obesity-induced inflammation. Efficient delivery of therapeutic anti-inflammatory molecules, such as interleukin (IL)-10, to macrophages can dramatically improve therapeutic efficacy of obesity treatments. We used liposomes containing the 'eat me' signal phosphatidylserine (PS) (PS-containing liposomes; PSL), which have macrophage targeting ability and anti-inflammatory functions, as a biomaterial carrier for the delivery of IL-10 to macrophages. The IL-10-conjugated PSL (PSL IL10) showed high affinity for macrophages. In obese mice, PSL-IL10 treatment exhibited significant anti-obesity and anti-inflammatory effects, such as reduced serum total cholesterol, adipocyte size, crown-like structures, proinflammatory cytokine secretion (IL-6 and tumor necrosis factor alpha) in adipose tissue, liver injury, hepatic steatosis, and inflammation foci, while treatment with IL 10 or PSL alone did not. These findings suggest that the PSL-IL10 has macrophage targeting ability and enhanced anti-inflammatory effect due to the synergistic anti-inflammatory effects of IL-10 and PSL, and can be used as a macrophage targeted therapeutic material for inflammation-related diseases, including obesity. PMID- 27716476 TI - Temporal variation of post-accident atmospheric 137Cs in an evacuated area of Fukushima Prefecture: Size-dependent behaviors of 137Cs-bearing particles. AB - The concentrations of 137Cs in the air, which were divided into coarse (>1.1 MUm phi) and fine (<1.1 MUm phi) fractions of particulate matter (PM), were measured from October 2012 to December 2014 in an area evacuated after the Fukushima Dai ichi Nuclear Power Plant (FDNPP) accident. Total atmospheric 137Cs concentrations showed a clear seasonal variation, with high concentrations during summer and autumn related to the dominant easterly wind blowing from the highly radioactivity contaminated area. This seasonal peak was dominated by 137Cs in the coarse PM fraction. The 137Cs specific activity (massic 137Cs concentration) in the coarse PM was also found to increase significantly in summer, whereas that in the fine PM showed no variability during the year. These results show that coarse and fine 137Cs-bearing PM have different origins and behaviors in the resuspension process. The seasonal variation in atmospheric 137Cs concentration was well correlated with the mean 137Cs surface contamination (deposition density) around the observation site weighted by the frequency of wind direction, indicating that the atmospheric 137Cs concentration in the observation site was explained by the distribution of the 137Cs surface contamination and the frequency of different wind directions. We introduced a resuspension factor corrected for wind direction, consisting of the ratio of the atmospheric 137Cs concentration to the weighted mean 137Cs surface contamination, which evaluated the intensity of resuspension better than the conventional resuspension factor. This ratio ranged from 5.7 * 10-11 to 8.6 * 10-10 m-1 and gradually decreased during the study period. PMID- 27716477 TI - Maternal trajectories of cigarette use as a function of maternal age and race. AB - BACKGROUND: Patterns of smoking vary as a function of age and race. The goals of this study were to identify trajectories of maternal cigarette use over a 17-year span, and to determine if maternal age at first birth and race were associated with smoking trajectories. METHODS: Pregnant women (N=690) were recruited at an urban prenatal clinic. The women (13-42years old; 62% African-American, 38% White) were interviewed about cigarette use during pregnancy and 6, 10, 14, and 16years postpartum. Growth mixture modeling (GMM) was used to identify trajectories. Regressions were used to determine if maternal age at first birth and race predicted trajectory class membership. RESULTS: A GMM of maternal cigarette use delineated 5 groups: none/unlikely to use (33%), decreasing likelihood of use (6%), late desistance (5%), increasing likelihood of use (17%), and chronic use (39%). Women who became mothers at a younger age were more likely to be classified as late desisters or increasingly likely to smoke. White mothers were more likely to be chronic smokers. Different smoking trajectories and predictors of trajectories were identified for the African-American and White mothers. Covariates including prenatal substance use, hostility, education, and economic hardship also differentiated smoking trajectories. CONCLUSIONS: Both prevention and treatment of smoking should be targeted to specific groups by age of first pregnancy and race. Pregnant smokers should be provided with more information and resources to help them avoid cigarettes during pregnancy and maintain abstinence after pregnancy.

AB - PURPOSE: The primary analysis of the ASPECCT study demonstrated that panitumumab was non-inferior to cetuximab for overall survival (OS) in patients with chemotherapy-refractory wild-type KRAS exon 2 metastatic colorectal cancer (mCRC). Here, we report the final analysis results of ASPECCT. PATIENTS AND METHODS: Patients with wild-type KRAS exon 2 mCRC who progressed on or were intolerant to irinotecan- or oxaliplatin-based chemotherapy were randomised to receive panitumumab 6 mg/kg once every 2 weeks or cetuximab (400 mg/m2) followed by 250 mg/m2 weekly. The primary end-point was OS assessed for non-inferiority. Patients were followed for survival for 24 months after the last patient was randomised and a final analysis was conducted. No formal hypothesis testing was done. Post hoc analyses of outcomes by prior bevacizumab exposure, worst-grade skin toxicity (0-1 versus 2-4) and worst-grade hypomagnesaemia (0 versus 1-4) were conducted. RESULTS: Nine hundred ninety-nine patients were randomised and received >=1 treatment dose (panitumumab, n = 499; cetuximab, n = 500). Median OS was 10.2 months with panitumumab versus 9.9 months with cetuximab (hazard ratio = 0.94; 95% confidence interval = 0.82-1.07). Median progression-free survival was 4.2 months with panitumumab and 4.4 months with cetuximab (hazard ratio = 0.98; 95% confidence interval = 0.87-1.12). Longer OS was observed for patients with increased skin toxicity and with hypomagnesaemia in both arms. Furthermore, OS was longer for patients with prior bevacizumab exposure treated with panitumumab than with cetuximab. The observed safety profiles were consistent with previous studies. CONCLUSION: Consistent with the primary analysis, the final analysis of ASPECCT showed panitumumab was non-inferior to cetuximab for OS for patients with chemotherapy-refractory, wild-type KRAS exon 2 mCRC.

AB - The anaphase-promoting complex or cyclosome (APC/C) is a ubiquitin ligase that polyubiquitinates specific substrates at precise times in the cell cycle, thereby triggering the events of late mitosis in a strict order. The robust substrate specificity of the APC/C prevents the potentially deleterious degradation of non APC/C substrates and also averts the cell-cycle errors and genomic instability that could result from mistimed degradation of APC/C targets. The APC/C recognizes short linear sequence motifs, or degrons, on its substrates. The specific and timely modification and degradation of APC/C substrates is likely to be modulated by variations in degron sequence and context. We discuss the extensive affinity, specificity, and selectivity determinants encoded in APC/C degrons, and we describe some of the extrinsic mechanisms that control APC/C substrate recognition. As an archetype for protein motif-driven regulation of cell function, the APC/C-substrate interaction provides insights into the general properties of post-translational regulatory systems. PMID- 27716481 TI - Physical Proximity of Sister Chromatids Promotes Top2-Dependent Intertwining. AB - Sister chromatid intertwines (SCIs), or catenanes, are topological links between replicated chromatids that interfere with chromosome segregation. The formation of SCIs is thought to be a consequence of fork swiveling during DNA replication, and their removal is thought to occur because of the intrinsic feature of type II topoisomerases (Top2) to simplify DNA topology. Here, we report that SCIs are also formed independently of DNA replication during G2/M by Top2-dependent concatenation of cohesed chromatids due to their physical proximity. We demonstrate that, in contrast to G2/M, Top2 removes SCIs from cohesed chromatids at the anaphase onset. Importantly, SCI removal in anaphase requires condensin and coincides with the hyperactivation of condensin DNA supercoiling activity. This is consistent with the longstanding proposal that condensin provides a bias in Top2 function toward decatenation. A comprehensive model for the formation and resolution of toxic SCI entanglements on eukaryotic genomes is proposed.

AB - How deregulation of chromatin modifiers causes malignancies is of general interest. Here, we show that histone H2A T120 is phosphorylated in human cancer cell lines and demonstrate that this phosphorylation is catalyzed by hVRK1. Cyclin D1 was one of ten genes downregulated upon VRK1 knockdown in two different cell lines and showed loss of H2A T120 phosphorylation and increased H2A K119 ubiquitylation of its promoter region, resulting in impaired cell growth. In vitro, H2A T120 phosphorylation and H2A K119 ubiquitylation are mutually inhibitory, suggesting that histone phosphorylation indirectly activates chromatin. Furthermore, expression of a phosphomimetic H2A T120D increased H3 K4 methylation. Finally, both VRK1 and the H2A T120D mutant histone transformed NIH/3T3 cells. These results suggest that histone H2A T120 phosphorylation by hVRK1 causes inappropriate gene expression, including upregulated cyclin D1, which promotes oncogenic transformation.

AB - During DNA double-strand break (DSB) repair, the ring-shaped Ku70/80 complex becomes trapped on DNA and needs to be actively extracted, but it has remained unclear what provides the required energy. By means of reconstitution of DSB repair on beads, we demonstrate here that DNA-locked Ku rings are released by the AAA-ATPase p97. To achieve this, p97 requires ATP hydrolysis, cooperates with the Ufd1-Npl4 ubiquitin-adaptor complex, and specifically targets Ku80 that is modified by K48-linked ubiquitin chains. In U2OS cells, chemical inhibition of p97 or siRNA-mediated depletion of p97 or its adapters impairs Ku80 removal after non-homologous end joining of DSBs. Moreover, this inhibition attenuates early steps in homologous recombination, consistent with p97-driven Ku release also affecting repair pathway choice. Thus, our data answer a central question regarding regulation of Ku in DSB repair and illustrate the ability of p97 to segregate even tightly bound protein complexes for release from DNA.

PMID- 27716484 TI - The Oscillating Stimulus Transporter Assay, OSTA: Quantitative Functional Imaging of Transporter Protein Activity in Time and Frequency Domains. AB - Transmembrane transporter proteins allow the passage of essentially all biologically important molecules across the lipid membranes of cells and organelles and are therefore of central importance to all forms of life. Current methods of transporter measurement, however, are lacking in several dimensions. Herein, a method is presented in which oscillating stimuli are presented to transporter-expressing cells, and activity is measured through imaging the corresponding oscillating responses of intracellular fluorescent sensors. This approach yields continuous temporal readouts of transporter activity and can therefore be used to measure time-dependent responses to drugs and other stimuli. Because of the periodic nature of the response, temporal Fourier transforms can be used to identify and quantify regions of interest in the xy plane and to overcome noise. This technique, called the Oscillating Stimulus Transporter Assay (OSTA), should greatly facilitate both functional characterization of transporters as well as high-throughput screening of drugs for transporters of particular pathophysiological interest.

PMID- 27716490 TI - Clinical presentation of not-just right experiences (NJREs) in individuals with OCD: Characteristics and response to treatment. AB - There is increasing recognition that instead of being motivated by a desire to prevent harm and reduce anxiety, some obsessive-compulsive symptoms may be driven by a desire to get things 'just right' or 'complete' and to reduce a sense of discomfort. However, existing data is largely from non-clinical samples. Therefore, in the current paper we examine the clinical presentation of not just right experiences (NJREs) in patients diagnosed with OCD and compare their experiences to both anxious and unselected controls. Then, we provide preliminary data on NJREs before and after cognitive behavioral therapy (exposure and response prevention). First, individuals with OCD were found to report experiencing significantly more NJREs and being more distressed by them compared to anxious controls and unselected controls. Next, there was some support for the specificity of NJREs to feelings of incompleteness. Finally, we found that after completing treatment, patients reported experiencing significantly less NJREs and experienced less distress associated with the NJREs. In conclusion we believe that more work on the role of NJREs is warranted and that characterizing OCD symptoms as either based on harm avoidance or incompleteness/NJREs may be a useful framework for classifying OCD symptoms. PMID- 27716491 TI - Injury severity measures for predicting return-to-work after a traumatic brain injury. AB - This study compared the ability of five injury severity measures, namely the Abbreviated Injury Scale to the Head (AIS-H), Glasgow Coma Scale (GCS), Glasgow Outcome Scale (GOS), Extended Glasgow Outcome Scale (GOSE), and Injury Severity Score (ISS), to predict return-to-work after a traumatic brain injury (TBI). Furthermore, factors potentially associated with return-to-work were investigated. In total, 207 individuals aged <=65 years newly diagnosed with a TBI and employed at the time of injury were recruited and followed-up for 1year by telephone every 3 months. A bivariate proportional hazards model analysis revealed that all five injury severity measures were significantly associated with return-to-work after a TBI. The AIS-H and non-head ISS explained 23.8% of the variation in the duration of returning to work from discharge after hospitalization for a TBI; similarly, the GCS, GOS, GOSE, and ISS respectively accounted for 4.7%, 21.4%, 12.9%, and 48.4% of the variation. A multivariable analysis revealed that individuals with higher injury severity as measured by the ISS (hazard ratio [HR], 0.94; 95% confidence interval [CI], 0.92-0.97), a lack of autonomy in transportation (HR, 2.55; 95% CI, 1.23-5.32), cognitive impairment (HR, 0.47; 95% CI, 0.28-0.79), and depression (HR, 0.97; 95% CI, 0.95-0.99) were significantly less likely to be employed after a TBI. In conclusion, of the five injury severity measures, the ISS may be the most capable measure of predicting return-to-work after a TBI. In addition to injury severity, autonomy in transportation, cognitive function, and the depressive status may also influence the employment status during the first year after a TBI. PMID- 27716492 TI - Prediction of secondary crash frequency on highway networks. AB - Secondary crash (SC) occurrences are major contributors to traffic delay and reduced safety, particularly in urban areas. National, state, and local agencies are investing substantial amount of resources to identify and mitigate secondary crashes to reduce congestion, related fatalities, injuries, and property damages. Though a relatively small portion of all crashes are secondary, determining the primary contributing factors for their occurrence is crucial. The non-recurring nature of SCs makes it imperative to predict their occurrences for effective incident management. In this context, the objective of this study is to develop prediction models to better understand causal factors inducing SCs. Given the count nature of secondary crash frequency data, the authors used count modeling methods including the standard Poisson and Negative Binomial (NB) models and their generalized variants to analyze secondary crash occurrences. Specifically, Generalized Ordered Response Probit (GORP) framework that subsumes standard count models as special cases and provides additional flexibility thus improving predictive accuracy were used in this study. The models developed account for possible effects of geometric design features, traffic composition and exposure, land use and other segment related attributes on frequency of SCs on freeways. The models were estimated using data from Shelby County, TN and results show that annual average daily traffic (AADT), traffic composition, land use, number of lanes, right side shoulder width, posted speed limits and ramp indicator are among key variables that effect SC occurrences. Also, the elasticity effects of these different factors were also computed to quantify their magnitude of impact. PMID- 27716493 TI - Lowering thresholds for speed limit enforcement impairs peripheral object detection and increases driver subjective workload. AB - Speed enforcement reduces incidences of speeding, thus reducing traffic accidents. Accordingly, it has been argued that stricter speed enforcement thresholds could further improve road safety. Effective speed monitoring however requires driver attention and effort, and human information-processing capacity is limited. Emphasizing speed monitoring may therefore reduce resource availability for other aspects of safe vehicle operation. We investigated whether lowering enforcement thresholds in a simulator setting would introduce further competition for limited cognitive and visual resources. Eighty-four young adult participants drove under conditions where they could be fined for travelling 1, 6, or 11km/h over a 50km/h speed-limit. Stricter speed enforcement led to greater subjective workload and significant decrements in peripheral object detection. These data indicate that the benefits of reduced speeding with stricter enforcement may be at least partially offset by greater mental demands on drivers, reducing their responses to safety-critical stimuli on the road. It is likely these results under-estimate the impact of stricter speed enforcement on real-world drivers who experience significantly greater pressures to drive at or above the speed limit. PMID- 27716494 TI - Mechanisms behind distracted driving behavior: The role of age and executive function in the engagement of distracted driving. AB - Performing secondary tasks, such as texting while driving, is associated with an increased risk of motor vehicle collisions (MVCs). While cognitive processes, such as executive function, are involved in driving, little is known about the relationship between executive control and willingness to engage in distracted driving. This study investigated the relationship between age, behavioral manifestations of executive function, and self-reported distracted driving behaviors. Executive difficulty (assessed with the BRIEF-A) as well as demographics (age and gender) was considered as possible predictors of engagement in distracted driving behaviors. Fifty-nine young, middle, and older adults self reported executive difficulty and weekly engagement in distracted driving behaviors. Results revealed that while partially accounted for by age, global executive difficulty was uniquely related to engagement in distracted driving behaviors. Older age was associated with fewer weekly self-reported distracted driving behaviors while higher self-reported executive difficulty was associated with more frequent weekly engagement in distracted behavior. No significant differences were found between young and middle-aged adults on distracted driving behaviors. Findings conclude that distracted driving is a ubiquitous phenomenon evident in drivers of all ages. Possible mechanisms underlying distracted driving behavior could potentially be related to deficits in executive function. PMID- 27716495 TI - Examining racial bias as a potential factor in pedestrian crashes. AB - INTRODUCTION: In the US people of color are disproportionately affected by pedestrian crashes. The purpose of this study was to examine the potential for racial bias in driver yielding behaviors at midblock crosswalks in low and high income neighborhoods located in the sprawling metropolitan area of Las Vegas, NV. METHODS: Participants (1 white, 1 black female) crossed at a midblock crosswalk on a multilane road in a low income and a high income neighborhood. Trained observers recorded (1) number of cars that passed in the nearest lane before yielding while the pedestrian waited near the crosswalk at the curb (2) number of cars that passed through the crosswalk with the pedestrian in the same half of the roadway. RESULTS: The first car in the nearest lane yielded to the pedestrian while they waited at the curb 51.5% of the time at the high income and 70.7% of the time at the low income crosswalk. Two way ANOVAs found an interaction effect between income and race on yielding behaviors. Simple effects for income revealed that at the high income crosswalk, drivers were less likely to yield to the white pedestrian while she waited at the curb (F(1,122)=11.18;p=0.001), and were less likely to yield to the black pedestrian while she was in the same half of the roadway at the high income crosswalk (F(1,124)=4.40;p=0.04). Simple effects for race showed significantly more cars passed through the crosswalk while the black pedestrian was in the roadway compared to the white pedestrian at the high income crosswalk (F(1,124)=6.62;p=0.01). CONCLUSIONS: Bias in driver yielding behavior may be one influencing factor in higher rates of pedestrian crashes for people of color. PMID- 27716497 TI - Knockout! Knockout! Who's Not There? PMID- 27716496 TI - Bone-targeted therapy use in patients with bone metastases from lung cancer: A systematic review of randomized controlled trials. AB - BACKGROUND: Patients with advanced lung cancer commonly have bone metastases. Compared with other malignancies, the use of bone-targeted agents (e.g. bisphosphonates and denosumab) is less common in lung cancer patients. This may be due to the perception that bone-targeted agents are less effective in this population. OBJECTIVE: To perform a systematic review to evaluate data from randomized trials of bone-targeted agents in lung cancer patients with bone metastases. METHODS: A systematic search of Medline, Embase and the Cochrane Register of Controlled Trials through May 2015 was performed. Randomized trials of bone-targeted therapies in lung cancer patients with bone metastases were sought. Outcomes studied included skeletal related events (SREs), pain, quality of life, progression-free survival and overall survival. Random effects meta analyses were planned if studies were judged homogeneous. RESULTS: Of 632 abstracts, 17 publications describing 13 studies were included. Sample sizes ranged between 50 and 1776. Of 3379 patients, 1903 had lung cancer, with subgroup data available for 8 of 13 studies. Patient demographics were comparable, but enrollment criteria and endpoints were heterogeneous across studies, precluding meta-analysis. Study-specific results suggested that bone-modifying agents reduce the incidence of SREs and bone pain in lung cancer patients. Three studies suggested a survival benefit. CONCLUSION: Data from included trials suggests benefit of bone-targeted agents in lung cancer for the prevention of SREs and bone pain. There is a trend toward improvement in overall survival and progression-free survival, although further research is needed. Impact on quality of life and key subgroups for benefit both require future research. PMID- 27716498 TI - Rett Syndrome and the Ongoing Legacy of Close Clinical Observation.

PMID- 27716505 TI - Abiotic Stress Signaling and Responses in Plants. AB - As sessile organisms, plants must cope with abiotic stress such as soil salinity, drought, and extreme temperatures. Core stress-signaling pathways involve protein kinases related to the yeast SNF1 and mammalian AMPK, suggesting that stress signaling in plants evolved from energy sensing. Stress signaling regulates proteins critical for ion and water transport and for metabolic and gene expression reprogramming to bring about ionic and water homeostasis and cellular stability under stress conditions. Understanding stress signaling and responses will increase our ability to improve stress resistance in crops to achieve agricultural sustainability and food security for a growing world population. PMID- 27716506 TI - Field Guide to Plant Model Systems. AB - For the past several decades, advances in plant development, physiology, cell biology, and genetics have relied heavily on the model (or reference) plant Arabidopsis thaliana. Arabidopsis resembles other plants, including crop plants, in many but by no means all respects. Study of Arabidopsis alone provides little information on the evolutionary history of plants, evolutionary differences between species, plants that survive in different environments, or plants that access nutrients and photosynthesize differently. Empowered by the availability of large-scale sequencing and new technologies for investigating gene function, many new plant models are being proposed and studied. PMID- 27716508 TI - Regulation of the CUL3 Ubiquitin Ligase by a Calcium-Dependent Co-adaptor. AB - The ubiquitin ligase CUL3 is an essential regulator of neural crest specification whose aberrant activation has been linked to autism, schizophrenia, and hypertension. CUL3 exerts its roles by pairing with ~90 distinct substrate adaptors, yet how the different CUL3-complexes are activated is poorly understood. Here, we show that CUL3 and its adaptor KLHL12 require two calcium binding proteins, PEF1 and ALG2, for recognition of their substrate SEC31. PEF1 and ALG2 form a target-specific co-adaptor that translates a transient rise in cytosolic calcium levels into more persistent SEC31 ubiquitylation, which in turn triggers formation of large COPII coats and promotes collagen secretion. As calcium also instructs chondrocyte differentiation and collagen synthesis, calcium-dependent control of CUL3KLHL12 integrates collagen secretion into broader programs of craniofacial bone formation. Our work, therefore, identifies both calcium and CUL3 co-adaptors as important regulators of ubiquitylation events that control human development. PMID- 27716507 TI - Host-Protozoan Interactions Protect from Mucosal Infections through Activation of the Inflammasome. AB - While conventional pathogenic protists have been extensively studied, there is an underappreciated constitutive protist microbiota that is an integral part of the vertebrate microbiome. The impact of these species on the host and their potential contributions to mucosal immune homeostasis remain poorly studied. Here, we show that the protozoan Tritrichomonas musculis activates the host epithelial inflammasome to induce IL-18 release. Epithelial-derived IL-18 promotes dendritic cell-driven Th1 and Th17 immunity and confers dramatic protection from mucosal bacterial infections. Along with its role as a "protistic" antibiotic, colonization with T. musculis exacerbates the development of T-cell-driven colitis and sporadic colorectal tumors. Our findings demonstrate a novel mutualistic host-protozoan interaction that increases mucosal host defenses at the cost of an increased risk of inflammatory disease. PMID- 27716509 TI - A Force-Induced Directional Switch of a Molecular Motor Enables Parallel Microtubule Bundle Formation. AB - Microtubule-organizing centers (MTOCs) nucleate microtubules that can grow autonomously in any direction. To generate bundles of parallel microtubules originating from a single MTOC, the growth of multiple microtubules needs to coordinated, but the underlying mechanism is unknown. Here, we show that a conserved two-component system consisting of the plus-end tracker EB1 and the minus-end-directed molecular motor Kinesin-14 is sufficient to promote parallel microtubule growth. The underlying mechanism relies on the ability of Kinesin-14 to guide growing plus ends along existing microtubules. The generality of this finding is supported by yeast, Drosophila, and human EB1/Kinesin-14 pairs. We demonstrate that plus-end guiding involves a directional switch of the motor due to a force applied via a growing microtubule end. The described mechanism can account for the generation of parallel microtubule networks required for a broad range of cellular functions such as spindle assembly or cell polarization.

AB - Understanding human embryonic ventral midbrain is of major interest for Parkinson's disease. However, the cell types, their gene expression dynamics, and their relationship to commonly used rodent models remain to be defined. We performed single-cell RNA sequencing to examine ventral midbrain development in human and mouse. We found 25 molecularly defined human cell types, including five subtypes of radial glia-like cells and four progenitors. In the mouse, two mature fetal dopaminergic neuron subtypes diversified into five adult classes during postnatal development. Cell types and gene expression were generally conserved across species, but with clear differences in cell proliferation, developmental timing, and dopaminergic neuron development. Additionally, we developed a method to quantitatively assess the fidelity of dopaminergic neurons derived from human pluripotent stem cells, at a single-cell level. Thus, our study provides insight into the molecular programs controlling human midbrain development and provides a foundation for the development of cell replacement therapies. PMID- 27716512 TI - Adolescent self-injurers: Comparing non-ideators, suicide ideators, and suicide attempters. AB - Adolescent non-suicidal self-injury (NSSI) and suicidality are serious health concerns; however, factors that contribute to the transition from NSSI to suicide ideation and suicide attempts are unclear. To address this gap, we investigated whether demographic characteristics, child maltreatment, and psychiatric factors are associated with the level suicidality among adolescents with a history of self-injury. Participants were three groups of adolescent inpatient self-injurers (n = 397, 317 female), aged 13-18 years (M = 15.44, SD = 1.36): (a) non-ideators (n = 96; no current suicide ideation and no lifetime suicide attempts), (b) suicide ideators (n = 149; current ideation and no lifetime attempts), and (c) suicide attempters (n = 152; current ideation and at least one lifetime attempt). Participants completed interviews assessing psychiatric diagnoses, suicidality, and NSSI characteristics, as well as questionnaires on childhood trauma, psychiatric symptoms, and risky behavior engagement. Depression severity was associated with greater odds being a suicide ideator (p < 0.001, OR = 1.04) and an attempter (p < 0.001, OR = 1.05) compared to a non-ideator. Suicide attempters used more NSSI methods and reported greater risky behavior engagement than non ideators (p = 0.03, OR = 1.29 and p = 0.03, OR = 1.06, respectively) and ideators (p = 0.015, OR = 1.25 and p = 0.04, OR = 1.05, respectively); attempters used more severe NSSI methods (e.g., burning). Our results identify a wide range of risk markers for increasing lethality in a sample at high risk for suicide mortality; future research is needed to refine risk assessments for adolescent self-injurers and determine the clinical utility of using risk markers for screening and intervention.

PMID- 27716514 TI - Mood disorders and biological rhythms in young adults: A large population-based study. AB - BACKGROUND: It is known that sleep disturbance has been considered a trait-marker of mood disorders. However, the role of disruptions in biological rhythms, such as eating, activity, and social patterns, needs to be better understood. AIM: To assess the differences in biological rhythms in subjects with bipolar disorder, major depressive disorder, and healthy controls. We also tested the association between disruptions of biological rhythms and circadian preferences. METHODS: A cross-sectional, population-based study with a representative sample of 1023 young adults. Bipolar disorder and depression were diagnosed using The Mini International Neuropsychiatric Interview - PLUS and DSM Structured Clinical Interview. Self-reported biological rhythms and circadian preference were assessed using the Biological Rhythm Interview of Assessment in Neuropsychiatry (BRIAN). RESULTS: Bipolar disorders and depression subjects presented higher rates of disruption in biological rhythms when compared to healthy controls even after adjusting for sex, socioeconomic status, alcohol, tobacco, illicit drug use, anxiety disorder and psychotropic medication use. Euthymic subjects showed higher biological rhythm disruption when compared to controls. Higher disruption in biological rhythms was observed in subjects with evening preferences. CONCLUSION: Higher disruption in biological rhythms occurs in individuals with depression and bipolar disorder even on periods of euthymia. PMID- 27716513 TI - Specific expectancies are associated with symptomatic outcomes and side effect burden in a trial of chamomile extract for generalized anxiety disorder. AB - OBJECTIVE: Patient expectancies are hypothesized to contribute to the efficacy and side effects of psychiatric treatments, but little research has investigated this hypothesis in the context of psychopharmacological therapies for anxiety. We prospectively investigated whether expectancies predicted efficacy and adverse events in oral therapy for Generalized Anxiety Disorder (GAD), controlling for confounding patient characteristics correlating with outcomes. METHODS: Expectancies regarding treatment efficacy and side effects were assessed at baseline of an eight week open-label phase of a trial of chamomile for Generalized Anxiety Disorder (GAD). The primary outcome was patient-reported GAD 7 scores, with clinical response and treatment-emergent side-effects as secondary outcomes. Expectancies were used to predict symptomatic and side-effect outcomes. RESULTS: Very few baseline patient characteristics predicted either type of expectancy. Controlling for a patient's predicted recovery based on their baseline characteristics, higher efficacy expectancies at baseline predicted greater change on the GAD-7 (adjusted beta = -0.19, p = 0.011). Efficacy expectancies also predicted a higher likelihood of attaining clinical response (adjusted odds ratio = 1.69, p = 0.002). Patients with higher side effect expectancies reported more side effects (adjusted log expected count = 0.26, p = 0.038). Efficacy expectancies were unrelated to side effect reports (log expected count = -0.05, p = 0.680), and side effect expectancies were unrelated to treatment efficacy (beta = 0.08, p = 0.306). CONCLUSIONS: Patients entering chamomile treatment for GAD with more favorable self-generated expectancies for the treatment experience greater improvement and fewer adverse events. Aligning patient expectancies with treatment selections may optimize outcomes. REGISTRATION: Trial Number NCT01072344 at ClinicalTrials.gov. PMID- 27716517 TI - Enhanc(er)ing Skin Stem Cells.

PMID- 27716523 TI - Layer-by-layer nanocoating of live Bacille-Calmette-Guerin mycobacteria with poly(I:C) and chitosan enhances pro-inflammatory activation and bactericidal capacity in murine macrophages. AB - Tuberculosis (TB) is a major disease burden globally causing more than 1.5 million deaths per year. The attenuated live vaccine strain Bacille Calmette Guerin (BCG), although providing protection against childhood TB, is largely ineffective against adult pulmonary TB. A major aim therefore is to increase the potency of the BCG vaccine to generate stronger and more sustained immunity against TB. Here, we investigated the use of layer-by-layer (LbL) nanocoating of the surface of live BCG with several layers of polyinosinic-polycytidylic acid (poly(I:C)), a strong inducer of cell-mediated immunity, and the biodegradable polysaccharide chitosan to enhance BCG immunogenicity. Nanocoating of live BCG did not affect bacterial viability or growth in vitro but induced killing of the BCG in infected mouse bone marrow-derived macrophages and enhanced macrophage production of pro-inflammatory cytokines and expression of surface co-stimulatory molecules relative to uncoated BCG. In addition, poly(I:C) surface-coated BCG, but not BCG alone or together with soluble poly(I:C), induced high production of nitric oxide (NO) and IL-12. These results argue that BCG and surface absorbed poly(I:C) act in a synergistic manner to elicit pro-inflammatory macrophage activation. In conclusion, nanocoating of live BCG with the immunostimulatory agent poly(I:C) may be an appropriate strategy to enhance and modulate host responses to the BCG vaccine.

AB - While various material factors have been shown to influence cell behaviors, recent studies started to pay attention to the effects of some material cues on "subcellular" geometry of cells, such as self-deformation of cell nuclei. It is particularly interesting to examine whether a self deformation happens discontinuously like a first-order transition and whether subcellular geometry influences significantly the extent of stem cell differentiation. Herein we prepared a series of micropillar arrays of poly(lactide-co-glycolide) and discovered a first-order transition of nuclear shape as a function of micropillar height under the examined section area and interspacing of the pillars. The deformed state of the nuclei of mesenchymal stem cells (MSCs) was well maintained even after osteogenic or adipogenic induction for several days. The nuclear deformation on the micropillar arrays was accompanied with smaller projected areas of cells, but led to an enhanced osteogenesis and attenuated adipogenesis of the MSCs, which is different from the previously known relationship between morphology and differentiation of stem cells on flat substrates. Hence, the present study reveals that the geometry of cell nuclei may afford a new cue to regulate the lineage commitment of stem cells on the subcellular level. PMID- 27716525 TI - Activation induced cytidine deaminase mutant (AID-His130Pro) from Hyper IgM 2 patient retained mutagenic activity on SHM artificial substrate. AB - Activation induced cytidine deaminase (AID) is an essential enzyme for class switch recombination (CSR) and somatic hypermutation (SHM) during secondary immune response. Mutations in the AICDA gene are responsible for Hyper IgM 2 syndrome where both CSR and SHM or only CSR are affected. Indeed, triggering either of the two mechanisms requires the DNA deamination activity of AID. Besides, different domains of AID may be differentially involved in CSR and SHM through their interaction with specific cofactors. Herein, we studied the AID induced SHM activity of the AID-His130Pro mutant identified in a patient with Hyper IgM 2 syndrome. AID mutagenic activity was monitored by the reversion of nonsense mutations of the EGFP gene assessed by flow cytometry. We found that the His130Pro mutation, which affects CSR, preserves AID mutagenic activity. Indeed, the His130 residue is located in a putative specific CSR region in the APOBEC like domain, known to involve CSR specific cofactors that probably play a major role in AID physiological activities. PMID- 27716526 TI - Evolution and demography of the great apes. AB - The great apes are the closest living relatives of humans. Chimpanzees and bonobos group together with humans, while gorillas and orangutans are more divergent from humans. Here, we review insights into their evolution pertaining to the topology of species and subspecies and the reconstruction of their demography based on genome-wide variation. These advances have only become possible recently through next-generation sequencing technologies. Given the close relationship to humans, they provide an important evolutionary context for human genetics. PMID- 27716527 TI - Nanomedicine-based paclitaxel induced apoptotic signaling pathways in A562 leukemia cancer cells. AB - In the present study, we have synthesized an amphiphilic pH-sensitive structure of poly(ethylene glycol) methyl ether-b-(poly lactic acid-co-poly(b-amino esters)) (MPEG-b-(PLA-co-PAE)) to load paclitaxel to increase the therapeutic efficacy in leukemia. The micelles exhibit excellent drug-loading capacities for paclitaxel (PTX) and exhibited a typical pH-responsive drug release pattern. The release of PTX from the micelles was significantly accelerated by decreasing pH from 7.4 to 5.0 which just fitted the pathological process. The most important advantage of this design is that the polymeric micelles provide an effective approach for rapid transport of cargo into the cytosol, which significantly increases the antitumor efficacy of PTX against K562 cancer cells. Paclitaxel loaded polymer micelles (PTX-M) showed significantly higher cytotoxic effect than that of free PTX. The PTX-M exhibited a superior apoptosis effect in cancer cells compared to that of free PTX at all time points. We have showed that the PTX-M activated upstream of apoptosis signaling and inhibited the anti-apoptotic factors. The PTX-M remarkably increased the upregulation of Bax, caspase-3, caspase-9, and PARP-1 expression and downregulated the Bcl-2 expression in K562 cancer cells. The results show that PTX-M induced cell apoptosis through intrinsic apoptotic signaling pathway. Importantly, PTX had a remarkably prolonged plasma circulation time after administration of PTX-M. Overall, this novel cancer specific, pH-responsive, and potentially in vivo stable unimolecular micelles may provide a very promising approach for targeted cancer therapy in the effective treatment of Leukemia. PMID- 27716528 TI - PEG-mimetic peptoid reduces protein fouling of polysulfone hollow fibers. AB - Biofouling is a persistent problem for membranes exposed to blood or other complex biological fluids, affecting surface structure and hindering performance. In this study, a peptoid with 2-methoxyethyl (NMEG5) side chains was immobilized on polysulfone hollow fiber membranes to prevent protein fouling. The successful attachment of NMEG5 to the polysulfone surface was confirmed by X-ray photoelectron spectroscopy and an increase in hydrophilicity was confirmed by contact angle analysis. The NMEG5-modified surface was found to resist fouling with bovine serum albumin, lysozyme, and adsorbed significantly less fibrinogen as compared with other published low-fouling surfaces. Due to the low fouling nature and increased biocompatibility of the NMEG5 coated membranes, they have potential applicability in numerous biomedical applications including artificial lungs and hemodialysis. PMID- 27716529 TI - Interaction of curcumin with 1,2-dioctadecanoyl-sn-glycero-3-phosphocholine liposomes: Intercalation of rhamnolipids enhances membrane fluidity, permeability and stability of drug molecule. AB - Stability of curcumin in neutral and alkaline buffer conditions has been a serious concern for its medicinal applications. We demonstrate that the stability of curucmin can be improved in 1,2-Dioctadecanoyl-sn-glycero-3-phosphocholine (DSPC) liposomes. Curcumin strongly partition into liquid crystalline phase compared to solid gel phase of DSPC liposomes. Variation of fluorescence intensity of curcumin associated with liposomes with temperature successfully determines phase transition temperature of DSPC liposomes. However, at higher molar ratio curcumin can influence phase transition temperature by intercalating into deep hydrophobic layer of liposomes and facilitating fusion of two membrane phases. Rhamnolipids (RLs) are recently being applied for various biomedical applications. Here, we have explored new insight on intercalation of rhamnolipids with DSPC liposomes. Intercalation of rhamnolipids exceptionally increases partition of curcumin into solid gel phase of DSPC liposomes, whereas this increase is moderate in liquid crystalline phase. Fluorescence quenching study establishes that permeability and fluidity of the DSPC liposomes are enhanced in the presence of RLs. Membrane permeability and fluidity can be improved further by increasing the percentage of RLs in DSPC liposomes. The phase transition temperature of DSPC liposomes decreases with increase in percentage of RLs in DSPC liposomes by encouraging fusion between solid gel and liquid crystalline phases. Intercalation of RLs is found to further boost stability of drug, curcumin, in DSPC liposomes. Thus, mixing RLs with DSPC liposomes could potentially serve as a good candidate for drug delivery application. PMID- 27716530 TI - Naringin protects against lipopolysaccharide-induced cardiac injury in mice. AB - Previous research has demonstrated that lipopolysaccharide (LPS) can induce sepsis and lead to myocardial dysfunction. Naringin has various biological activities in LPS-induced sepsis. In this study, our aim was to investigate the effects of Naringin on LPS-induced cardiac injury and clarify its potential mechanism. We found that in vivo treatment with Naringin significantly ameliorated body weight loss, and attenuated cardiac histopathological changes after LPS challenge. Furthermore, Naringin inhibited LPS-induced increase of TNF alpha, IL-1beta and IL-6 activities to alleviate inflammatory response in heart. Moreover, Naringin supplement dramatically increased SOD levels, and prevented MDA levels to ameliorate oxidative stress compared with the LPS group in heart. Lastly, treatment with Naringin also significantly decreased the ratio of BAX to BCL-2 to resist apoptosis in heart. It is concluded that Naringin may be a promising therapeutic agent on LPS-induced cardiac injury by anti-inflammatory, anti-oxidant and anti-apoptotic effects. PMID- 27716531 TI - Chlorhexidine possesses unique cytotoxic actions in rat thymic lymphocytes: Its relation with electrochemical property of membranes. AB - Chlorhexidine (CHX) is an antibacterial agent used in various types of pharmaceutical products. Therefore, CHX is easily found around us. Owing to its positive charge, the electrochemical property of cell membranes was assumed to be a key point of cytotoxic action of CHX. Depolarization of membranes attenuated the cytotoxic action of CHX in rat thymic lymphocytes. CHX interfered with annexin V binding to membranes. Manipulations to induce exposure of phosphatidylserine on the outer membrane surface augmented the cytotoxic action of CHX, indicating that changes in the electrochemical property of membranes affected the cytotoxic action of CHX. Hence, CHX might kill cells physiologically undergoing apoptosis, resulting instead in necrotic cell death. However, the threshold CHX concentration in this in vitro study was slightly higher than blood CHX concentrations observed clinically. Therefore, these results may support the safety of CHX use although CHX possesses unique cytotoxic actions described in this study. PMID- 27716532 TI - Potential anti-inflammatory natural products from marine algae. AB - Inflammatory diseases have become one of the leading causes of health issue throughout the world, having a considerable influence on healthcare costs. With the emerging developments in natural product, synthetic and combinatorial chemistry, a notable success has been achieved in discovering natural products and their synthetic structural analogs with anti-inflammatory activity. However, many of these therapeutics have indicated detrimental side effects upon prolonged usage. Marine algae have been identified as an underexplored reservoir of unique anti-inflammatory compounds. These include polyphenols, sulfated polysaccharides, terpenes, fatty acids, proteins and several other bioactives. Consumption of these marine algae could provide defense against the pathophysiology of many chronic inflammatory diseases. With further investigation, algal anti inflammatory phytochemicals have the potential to be used as therapeutics or in the synthesis of structural analogs with profound anti-inflammatory activity with reduced side effects. The current review summarizes the latest knowledge about the potential anti-inflammatory compounds discovered from marine algae. PMID- 27716533 TI - Curcumin-cyclodextrin complexes enhanced the anti-cancer effects of curcumin. AB - Curcumin (CUR), as a yellow pigment in the spice turmeric (Curcuma longa), possessed a pleiotropic application containing cancer therapy. Due to its poor oral bioavailability, the objective of this study was to investigate the use of curcumin-cyclodextrin complexes (CD15) as an approach to cancer chemoprevention. In this study, CUR encapsulation into the beta-cyclodextrin (CD) cavity was achieved by the saturated aqueous solution method. CD15 was characterized by Fourier transform infrared (FTIR) and UV spectra analyses. An optimized CD15 was evaluated by cellular uptake and anti-cancer activity. As a result, CD15 enhanced curcumin delivery and improved its therapeutic efficacy compared with free curcumin in vivo and in vitro. Therefore, through regulation of MAPK/NF-kappaB pathway, CD15 up-regulated p53/p21 pathway, down-regulated CyclinE-CDK2 combination and increased Bax/caspase 3 expression to induce cellar apoptosis and G1-phase arrest. In conclusion, these results suggested that CD15 formulation should be used as a system for improving curcumin delivery and its therapeutic efficacy in lung cancer. PMID- 27716534 TI - Low dose extended exposure to saxitoxin and its potential neurodevelopmental effects: A review. AB - Saxitoxin (STX) and its analogs, the paralytic shellfish toxins (PSTs), are a group of potent neurotoxins well known for their role in acute paralytic poisoning by preventing the generation of action potentials in neuronal cells. They are found in both marine and freshwater environments globally and although acute exposure from the former has previously received more attention, low dose extended exposure from both sources is possible and to date has not been investigated. Given the known role of cellular electrical activity in neurodevelopment this pattern of exposure may be a significant public health concern. Additionally, the presence of PSTs is likely to be an ongoing and possibly increasing problem in the future. This review examines the neurodevelopmental toxicity of STX, the risk of extended or repeated exposure to doses with neurodevelopmental effects, the potential implications of this exposure and briefly, the steps taken and difficulties faced in preventing exposure. PMID- 27716537 TI - Colorectal cancer incidence in 5 Asian countries by subsite: An analysis of Cancer Incidence in Five Continents (1998-2007). AB - Colorectal cancer is the fourth most common cancer in Asia. However, the trends in colorectal cancer incidence by subsite have not been analyzed across Asian countries. We used the most recent, high quality data from 6 cancer registries for two 5-year periods, 1998-2002 and 2003-2007, from Cancer Incidence in Five Continents to estimate colorectal cancer incidence by subsite in 5 Asian countries. Cases with overlapping lesions or otherwise unspecified colon cancer were re-distributed as proximal or distal colon cancer. Age-standardized incidence rates (ASRs) per 100,000 population and incidence rate ratios from 1998 to 2002 to 2003-2007 were calculated for each subsite. For 2003-2007, men in Miyagi, Japan, had the highest ASR for cancer in the proximal colon, distal colon and rectum. Men of Jewish ancestry in Israel had a high ASR for proximal and distal colon cancer, but the lowest ASR for rectal cancer. The proportion of rectal cancer was highest among Korean men (51.39%) and lowest among Israeli women (26.6%). From 1998-2002 to 2003-2007, rectal cancer incidence did not significantly change in most registries, except for men in Miyagi, Japan, and both sexes in Korea. However, during the same period cancer incidence in the proximal and distal colon increased in most registries. In conclusion, there was substantial variation in subsite distributions of colorectal cancer in Asian registries and increases in overall incidence of colorectal cancer could be attributed to increases in colon cancer. PMID- 27716536 TI - An in vivo assay performed using multiple biomarkers related to testosterone synthesis and conversion for assessing the androgenic potency of refuse leachate. AB - Refuse leachate is likely an important source of androgens. However, common in vitro bioassays underestimate the potential androgenic activity of leachate, owing to non-receptor-mediated mechanisms that modify the balance of sex hormones and promote the accumulation of endogenous androgens. This study aimed to develop an in vivo assay by using multiple biomarkers related to testosterone synthesis and conversion for assessing the potential androgenic activity of refuse leachate sampled from a municipal solid waste treatment plant in Qingdao, China. The results indicated that exposure to leachate increased the levels of testosterone and luteinizing hormone, but decreased those of 17beta-estradiol in both male and female goldfish (Carassius auratus), suggesting a potential androgenic activity. Further, Leydig cell hyperplasia and decreased gonadal P450 aromatase mRNA levels were observed; these alterations might promote the biosynthesis of testosterone and hinder the conversion of testosterone to 17beta-estradiol, which in turn enhance testosterone accumulation. Exposure to leachate also resulted in reproductive impairments, including decreased gonadosomatic index and plasma vitellogenin levels of female goldfish, as well as decreased testicular enzyme activities in male goldfish. The integrated use of biochemical, molecular, and histological markers not only improved our understanding of the androgenic effects of leachate but also verified the reliability and validity of the results. Therefore, the in vivo bioassay described in this study might allow the investigation of the androgenic effects of other complex contaminant mixtures in the future. PMID- 27716535 TI - Brain and cognitive functions in two groups of naive HIV patients selected for a different plan of antiretroviral therapy: A qEEG study. AB - OBJECTIVE: Cortical sources of electroencephalographic (EEG) rhythms were investigated in two sub-populations of naive HIV subjects, grouped based on clinical criteria to receive different combination anti-retroviral therapies (cARTs). These EEG sources were hypothesized to reflect beneficial effects of both regimes. METHODS: Eyes-closed resting state EEG data were collected in 19 (Group A) and 39 (Group B) naive HIV subjects at baseline (i.e. pre-treatment; T0) and after 5months of cART (T5). Compared with the Group A, the Group B was characterized by slightly worse serological parameters and higher cardiovascular risk. At T0, mean viral load (VL) and CD4 count were 87,694copies/ml and 435cells/MUl in the Group A and 187,370copies/ml and 331cells/MUl in the Group B. The EEG data were also collected in 50 matched control HIV-negative subjects. Cortical EEG sources were assessed by LORETA software. RESULTS: Compared to the Control Group, the HIV Groups showed lower alpha (8-12Hz) source activity at T0 while the Group B also exhibited higher delta source activity. The treatment partially normalized alpha and delta source activity in the Group A and B, respectively, in association with improved VL, CD4, and cognitive functions. CONCLUSIONS: Different cART regimens induced diverse beneficial effects in delta or alpha source activity in the two naive HIV Groups. SIGNIFICANCE: These sources might unveil different neurophysiological effects of diverse cART on brain function in naive HIV Groups as a function of clinical status and/or therapeutic compounds. PMID- 27716538 TI - Molecular dynamics of the honey bee toxin tertiapin binding to Kir3.2. AB - Tertiapin (TPN), a short peptide isolated from the venom of the honey bee, is a potent and selective blocker of the inward rectifier K+ (Kir) channel Kir3.2. Here we examine in atomic detail the binding mode of TPN to Kir3.2 using molecular dynamics, and deduce the key residue in Kir3.2 responsible for TPN selectivity. The binding of TPN to Kir3.2 is stable when the side chain of either Lys16 (TPNK16-Kir3.2) or Lys17 (TPNK17-Kir3.2) of the toxin protrudes into the channel pore. However, the binding affinity calculated from only TPNK17-Kir3.2 and not TPNK16-Kir3.2 is consistent with experiment, suggesting that Lys17 is the most plausible pore-blocking residue. The alanine mutation of Kir3.2-Glu127, which is not present in TPN-resistant channels, reduces the inhibitory ability of TPN by over 50 fold in TPNK17-Kir3.2, indicating that Kir3.2-Glu127 is important for the selectivity of TPN. PMID- 27716539 TI - Rorschach Performance Assessment System (R-PAS) and vulnerability to stress: A preliminary study on electrodermal activity during stress. AB - This study investigated the predictive validity of the ten Rorschach Performance Assessment System (R-PAS) variables from the Stress and Distress domain, by testing whether they predicted increased sympathetic reactivity to a mild, laboratory-induced stress, occurred one week after Rorschach administration. A relatively small student sample (N=52) contributed to this research: During a first meeting (T1) participants were administered the Rorschach task according to R-PAS guidelines; about one week later (T2) their electrodermal activity (EDA) was recorded during exposure to a mild laboratory stress-inducing task. Based on literature indicating that exposure to stress tends to increase physiological vulnerability/reactivity to stressful situations, we anticipated that Stress and Distress R-PAS variables measured at T1 would positively correlate with increased sympathetic reactivity to stress at T2, as indicated by greater EDA changes from baseline to stress and recovery. Results partially confirmed our hypotheses: (a) the mean of and (b) the majority of the Stress and Distress R-PAS variables were significantly correlated, in the expected direction, with medium and medium to large effect sizes. PMID- 27716540 TI - Immediate postpartum mood assessment and postpartum depressive symptoms. AB - BACKGROUND: Negative affect (NA) and positive affect (PA) in the early postpartum period have been associated with postpartum depressive symptoms, but the exact relationship is not well understood. This study aimed to determine if NA and PA in the immediate postpartum period predicted postpartum depressive symptoms over and above well-established predictors (previous trauma, history of depression). METHODS: Participants were prospectively recruited from a Mother-Baby Unit at a large Midwestern academic medical center in the United States from April 2011 to April 2014. Participants (N=526) completed the Daily Experiences Questionnaire (DEQ), a self-report measure which assessed NA and PA, within three days post delivery. Participants then reported their depressive symptoms at two weeks (n=364) and twelve weeks postpartum (n=271). RESULTS: Hierarchical regression analyses indicated that low PA and high NA after birth significantly predicted depressive symptoms early (at 2 weeks) and later (at 12 weeks) in the postpartum period, over and above previous traumatic experiences and history of depression. LIMITATIONS: The sample was relatively homogenous, and data were from self-report instruments. CONCLUSIONS: The current study found NA and PA in the days immediately after birth predicted depressive symptoms at multiple time points in the postpartum period. Because the perinatal period places women at a higher risk for depressive symptomatology, prevention and early intervention are critical. Measuring affect in hospitals immediately after birth may provide a more normalized set of items that is predictive of later depression, which will allow physicians to identify those at highest risk for developing depressive symptoms. PMID- 27716541 TI - Acquisition of CS-US contingencies during Pavlovian fear conditioning and extinction in social anxiety disorder and posttraumatic stress disorder. AB - BACKGROUND: Fear-based disorders, like social anxiety disorder (SAD) and posttraumatic stress disorder (PTSD), are characterized by an exaggerated fear response and avoidance to trigger cues, suggesting a transdiagnostic mechanism of psychopathology. Current theories suggest that abnormalities in conditioned fear is a primary contributor to the pathophysiology of these disorders. The primary goal of this study was to compare acquisition of conditioned stimulus (CS) and aversive unconditioned stimulus (US) contingencies during fear learning and extinction in individuals with SAD and PTSD. METHODS: In a standard Pavlovian fear conditioning-extinction paradigm we measured subjective US expectancy ratings to different CSs in patients with SAD (n=16) compared to patients with PTSD (n=13) and healthy controls (n=15) RESULTS: Both patient groups (SAD, PTSD) acquired differential conditioning between a CS that predicted US (CS+) and a CS that never predicted the US (CS-), however, both groups reported an increased expectancy that the US would occur following the CS-. Additionally, the PTSD group overestimated that the US would occur in general. Neither patient group showed evidence of successful extinction of the CS+-US contingency nor differentiated their expectation of US occurrence between the CS+ and CS- during extinction learning. LIMITATIONS: Group sample sizes were small and we did not include a trauma-exposed group without PTSD CONCLUSIONS: Both SAD and PTSD generalize expectations of an aversive outcome across CSs, even when a CS never signals an aversive outcome and PTSD may tend to over-expect threat. Fear learning and extinction abnormalities may be a core feature underlying shared symptoms across fear-based disorders. PMID- 27716543 TI - Deficiency in memory B cell compartment in a patient with infertility and recurrent pregnancy losses. AB - Alterations in normal balance of B cell subsets have been reported in various rheumatic diseases. In this study, we report a woman with a history of recurrent pregnancy losses (RPL) and infertility who had low levels of memory B cells. A 35 year-old woman with a history of RPL and infertility was demonstrated to have increased peripheral blood CD19+ B cells with persistently low levels of memory B cell subsets. Prior to the frozen donor egg transfer cycle, prednisone and intravenous immunoglobulin G (IVIg) treatment was initiated and patient achieved dichorionic diamniotic twin pregnancies. During pregnancy, proportion (%) of switched memory B cells CD27+IgD- increased, while percent of total CD19+ B cells and CD27-IgD+ naive B cells were gradually decreased with a high dose IVIg treatment. She developed cervical incompetence at 20 weeks of gestation, received a Cesarean section at 32 weeks of gestation due to preterm labor, and delivered twin babies. B cell subset abnormalities may be associated with infertility, RPL and preterm labor, and further investigation is needed. PMID- 27716544 TI - Amygdala-based intrinsic functional connectivity and anxiety disorders in adolescents and young adults. AB - Anxiety disorders (AD) are the most prevalent group of psychiatric disorders in adolescents and young adults. Nevertheless, the pathophysiology of anxiety disorders is still poorly understood. This study investigated differences in the functional connectivity of intrinsic amygdala-based networks of participants with and without AD. Resting state fMRI data were obtained from 18 participants with an AD and 19 healthy comparison individuals. Psychiatric diagnosis was assessed using standardized structured interviews. The comparison between groups was carried out using functional connectivity maps from six seed regions defined using probabilistic maps bilaterally within the amygdala (basolateral, superficial and centromedial amygdala). We found significant between-group differences in five clusters, which showed aberrant functional connectivity with the left basolateral amygdala: right precentral gyrus, right cingulate gyrus, bilateral precuneus, and right superior frontal gyrus in subjects with AD as compared with the comparison subjects. For the comparison subjects, the correlations between the amygdala and the five clusters were either non significant, or negative. The present study suggests there is an intrinsic disruption in the communication between left basolateral amygdala and a network of brain regions involved with emotion regulation, and with the default mode network in adolescents and young adults with anxiety disorders. PMID- 27716542 TI - Resting-state functional connectivity of the amygdala and longitudinal changes in depression severity in adolescent depression. AB - BACKGROUND: The incidence of major depressive disorder (MDD) rises during adolescence, yet the neural mechanisms of MDD during this key developmental period are unclear. Altered amygdala resting-state functional connectivity (RSFC) has been associated with both adolescent and adult MDD, as well as symptom improvement in response to treatment in adults. However, no study to date has examined whether amygdala RSFC is associated with changes in depressive symptom severity in adolescents. METHOD: We examined group differences in amygdala RSFC between medication-naive depressed adolescents (N=48) and well-matched healthy controls (N=53) cross-sectionally. We then longitudinally examined whether baseline amygdala RSFC was associated with change in depression symptoms three months later in a subset of the MDD group (N=24). RESULTS: Compared to healthy controls, depressed adolescents showed reduced amygdala-based RSFC with the dorsolateral prefrontal cortex (DLPFC)and the ventromedial prefrontal cortex (VMPFC). Within the depressed group, more positive baseline RSFC between the amygdala and insulae was associated with greater reduction in depression symptoms three months later. LIMITATIONS: Only a subset of depressed participants was assessed at follow-up and treatment type and delivery were not standardized. CONCLUSIONS: Adolescent depression may be characterized by dysfunction of frontolimbic circuits (amygdala-DLPFC, amygdala-VMPFC) underpinning emotional regulation, whereas those circuits (amygdala-insula) subserving affective integration may index changes in depression symptom severity and may therefore potentially serve as a candidate biomarker for treatment response. Furthermore, these results suggest that the biomarkers of MDD presence are distinct from those associated with change in depression symptoms over time. PMID- 27716546 TI - Effectiveness of light-reflecting devices: A systematic reanalysis of animal vehicle collision data. AB - Every year, approximately 500 human fatalities occur due to animal-vehicle collisions in the United States and Europe. Especially heavy-bodied animals affect road safety. For more than 50 years, light-reflecting devices such as wildlife warning reflectors have been employed to alert animals to traffic when crossing roads during twilight and night. Numerous studies addressed the effectiveness of light-reflecting devices in reducing collisions with animals in past decades, but yielded contradictory results. In this study, we conducted a systematic literature review to investigate whether light-reflecting devices contribute to an effective prevention of animal-vehicle collisions. We reviewed 53 references and reanalyzed original data of animal-vehicle collisions with meta analytical methods. We calculated an effect size based on the annual number of animal-vehicle collisions per kilometer of road to compare segments with and without the installation of light-reflecting devices for 185 roads in Europe and North America. Our results indicate that light-reflecting devices did not significantly reduce the number of animal-vehicle collisions. However, we observed considerable differences of effect sizes with respect to study duration, study design, and country. Our results suggest that length of the road segment studied, study duration, study design and public attitude (preconception) to the functioning of devices may affect whether the documented number of animal-vehicle collisions in- or decrease and might in turn influence whether results obtained were published. PMID- 27716545 TI - Youth with substance abuse histories exhibit dysfunctional representation of expected value during a passive avoidance task. AB - Individuals with substance abuse (SA) histories show impairment in the computations necessary for decision-making, including expected value (EV) and prediction error (PE). Neuroimaging findings, however, have been inconsistent. Sixteen youth with (SApositive) and 29 youth without (SAnegative) substance abuse histories completed a passive avoidance task while undergoing functional MRI. The groups did not significantly differ on age, gender composition or IQ. Behavioral results indicated that SApositive youth showed significantly less learning than SAnegative youth over the task. SApositive youth show problems representing EV information when attempting to avoid sub-optimal choices in bilateral inferior frontal gyrus and striatum. Furthermore, SApositive youth showed a significantly increased differential response to reward versus punishment feedback modulated by PE in posterior cingulate cortex relative to SAnegative youth. Disrupted decision making is likely to exacerbate SA as a failure to represent EV during the avoidance of sub-optimal choices is likely to increase the likelihood of SA. With respect to the representation of PE, future work will be needed to clarify the impact of different substances on the neural systems underpinning PE representation. Moreover, interaction of age/development and substance abuse on PE signaling will need to be explored. PMID- 27716547 TI - How do they feel? Patients' perspectives on draping and dignity in a physiotherapy outpatient setting: A pilot study. AB - BACKGROUND: Research to date has focused on dignity within the hospital rather than outpatient settings which is likely to raise different issues from the patients' perspective. PURPOSE: To investigate patients' views relating to draping and dignity and their choice of dressing options in the physiotherapy outpatient setting. METHOD: A custom-designed questionnaire was developed including feedback from a focus group of 10 individuals attending a physiotherapy outpatient clinic. The final version of the questionnaire comprised 14 items covering issues regarding privacy, draping, respect and communication. Patients attending outpatient physiotherapy for musculoskeletal treatment were invited to complete the questionnaire which was administered over a period of seven weeks. RESULTS: Of the 31 respondents completing the questionnaire (n = 23 females, n = 8 males), the majority of males (87.5% n = 7) felt very confident removing their clothing whereas 26.1% of females (n = 6) reported feeling confident when asked to remove their clothing. Female respondents also considered the gender of their physiotherapist (87% n = 21) as well as physical privacy (73.9% n = 17) to be important factors related to patient dignity. All male respondents (100%) expressed a preference for exposing the bare back whereas the females expressed mixed dressing preferences. The preferred dressing option for the lower body for both males and female respondent was sport shorts (87.5% n = 7; 81.8% n = 18 respectively). CONCLUSION: The patients' perspective of dignity and draping in a physiotherapy musculoskeletal settings is seen in terms of physical space, the provision of a range of draping options in conjunction with clear communication by their physiotherapist. PMID- 27716549 TI - Associations between quantitative measures of women's empowerment and access to care and health status for mothers and their children: A systematic review of evidence from the developing world. AB - Research on the association between women's empowerment and maternal and child health has rapidly expanded. However, questions concerning the measurement and aggregation of quantitative indicators of women's empowerment and their associations with measures of maternal and child health status and healthcare utilization remain unanswered. Major challenges include complexity in measuring progress in several dimensions and the situational, context dependent nature of the empowerment process as it relates to improvements in maternal and child health status and maternal care seeking behaviors. This systematic literature review summarizes recent evidence from the developing world regarding the role women's empowerment plays as a social determinant of maternal and child health outcomes. A search of quantitative evidence previously reported in the economic, socio-demographic and public health literature finds 67 eligible studies that report on direct indicators of women's empowerment and their association with indicators capturing maternal and child health outcomes. Statistically significant associations were found between women's empowerment and maternal and child health outcomes such as antenatal care, skilled attendance at birth, contraceptive use, child mortality, full vaccination, nutritional status and exposure to violence. Although associations differ in magnitude and direction, the studies reviewed generally support the hypothesis that women's empowerment is significantly and positively associated with maternal and child health outcomes. While major challenges remain regarding comparability between studies and lack of direct indicators in key dimensions of empowerment, these results suggest that policy makers and practitioners must consider women's empowerment as a viable strategy to improve maternal and child health, but also as a merit in itself. Recommendations include collection of indicators on psychological, legal and political dimensions of women's empowerment and development of a comprehensive conceptual framework that can guide research and policy making.

AB - Emigration has contributed to a shortage of doctors in many sub-Saharan African countries. Specialty training is highly valued by doctors and a potential tool for retention. Yet not all types of training may be valued equally. In the first study to examine preferences for postgraduate training in depth, we carried out a discrete choice experiment as part of a cross-sectional survey of all Malawian doctors within seven years of graduation and not yet in specialty training. Over August 2012 to March 2013, 148 doctors took part out of 153 eligible in Malawi. Despite evidence that specialty training is highly sought after, Malawian junior doctors would not accept all types of training. Doctors preferred timely training outside of Malawi in core specialties (internal medicine, general surgery, paediatrics, obstetrics & gynaecology). Specialty preferences are particularly strong, with most junior doctors requiring nearly double their monthly salary to accept training all in Malawi and over six-fold to accept training in ophthalmology (representing a bundle of unpopular but priority specialties). In contrast, the location of work before training did not significantly influence most doctors' choices when guaranteed specialty training. Using a latent class model, we identified four subgroups of junior doctors with distinct preferences. Policy simulations showed that these preferences could be leveraged by policymakers to improve retention in exchange for guaranteed specialty training, however incentivising the uptake of training in priority specialties will only be effective in those with more flexible preferences. These results indicate that indiscriminate expansion of postgraduate training to slow emigration of doctors from sub-Saharan African countries may not be effective unless doctors' preferences are taken into account.

PMID- 27716554 TI - Efficacy and safety of novel anticoagulants versus vitamin K antagonists in patients with mild and moderate to severe renal insufficiency: Focus on apixaban. AB - The high risk of both stroke and major bleeding in atrial fibrillation (AF) patients with chronic kidney disease (CKD) defines an important population for whom the assessment of the balance between the risk of ischemic stroke and of bleeding is essential. The use of novel oral anticoagulants (NOACs) may be a viable option in this population due to their greater net clinical benefit than warfarin, as demonstrated by the results of the clinical phase III trials. NOACs have been found to have a greater net clinical benefit than warfarin in patients at high risk of either stroke (CHADS2>=1 or CHA2DS2-VASc score>=2) or bleeding (HAS-BLED>=3). Noteworthy, it has been found also a positive net clinical benefit with apixaban and dabigatran 110mg BID in patients with CHADS2 score=0 and HAS BLED score>=3. At CHA2DS2-VASc score=1, apixaban and both doses of dabigatran were superior to warfarin in terms of the net clinical benefit. Available scientific evidence might help in clinical decision-making regarding the use of NOACs in patients with CKD who are at high risk for both stroke and bleeding. Overall, current findings provide a rationale for the choice of apixaban or rivaroxaban over dabigatran in patients with AF and stage III CKD. Out of the NOACs, only apixaban has been recently approved for the use in patients with end stage renal dysfunction on hemodialysis (the recommended dose of 5mg twice daily should be halved in patients with body weight of <=60kg and or age>=80years). PMID- 27716555 TI - Long-term outcomes of catheter ablation of atrial fibrillation post-cardiac valve replacement. AB - OBJECTIVE: The long-term outcomes of catheter ablation of atrial fibrillation (AF) developing post-cardiac valve replacement (VR) remain undefined. METHODS AND RESULTS: Eighty-nine post-VR patients with AF (44% longstanding persistent AF, LSP-AF) were enrolled. Cumulative success rate of circumferential pulmonary vein ablation (CPVA for paroxysmal AF) and bidirectional block of lines and disappearance of complex fractionated atrial electrograms (CFAEs for persistent and LSP-AF) as index and repeat procedural endpoints reached 57% (mean, 1.3 procedures) during the first year, and dropped to 42% at median follow-up of 40months (range, 24-70months) for multiple procedures (mean, 1.6+/-0.9 [1-5]); incidence of procedural complications was similar to that of conventional procedures. In multivariate analysis, larger right atrium (RA, 9.40 [2.64-33.36]; P=0.001) and rheumatic valvular disease etiology (OR, 5.49 [95% CI, 1.26-23.96]; P=0.023) were significant independent predictors of recurrent atrial tachyarrhythmia (ATa); in contrast, long-term freedom from ATa was comparable between single and double valve replacement groups (42.1% vs. 43.7%, P=0.880), or mechanical and bioprosthetic valves groups (41.7% vs. 50.0%, P=0.620). CONCLUSION: In this single-center prospective study, treatment of post-VR AF with commonly used ablation strategies including CPVA and linear and CFAE ablation had limited long-term success, with ATa recurrence risk appearing higher in the setting of RA enlargement and rheumatic valvular disease and unrelated to valves characteristics. PMID- 27716556 TI - A retrospective analysis of laser endartherectomy assisted balloon angioplasty for popliteal and infrapopliteal peripheral arterial disease. AB - OBJECTIVES: To describe our single center experience with the use of laser endartherectomy assisted balloon angioplasty in popliteal and infrapopliteal arterial disease. BACKGROUND: Peripheral arterial disease (PAD) carries significant morbidity to patients. Some patients may have multiple comorbid conditions potentially limiting therapeutic options for PAD. Endovascular interventions are aimed at decreasing arterial disease symptoms, improve wound healing and ultimately limb salvage. There is limited data on below the knee PAD and simultaneous laser endartherectomy use in this anatomic location. METHODS: The cohort comprised 41 patients that underwent laser assisted balloon angioplasty from 2010 to 2013. All patients had popliteal and infrapopliteal arterial disease. Outcomes evaluated were limb salvage and symptom relief 12months following the procedure. A comparison between the patients that underwent amputation and those with limb salvage was also performed. RESULTS: All the patients had TASC II (Trans Atlantic Inter-Society Consensus) type D lesions. Most patients reported persistent PAD symptoms by six months, with 17% remaining symptom free by 12months. Affected limb salvage was 69%. Five patients (12%) died and one third of the patients had a new peripheral angiogram. In the repeat angiogram, most patients showed initial target vessel occlusion. No statistically significant differences were found between the patients that preserved their limb to those who underwent amputation. CONCLUSIONS: Laser assisted balloon angioplasty use for complex popliteal and infrapopliteal arterial disease is a therapeutic option when limb salvage is the goal. Despite this, symptom recurrence and the need for repeated angiography continue to be high. PMID- 27716557 TI - Circulating level of pigment epithelium-derived factor is associated with vascular function and structure: A cross-sectional study. AB - BACKGROUND: Pigment epithelium-derived factor (PEDF) is a glycoprotein that belongs to the superfamily of serine protease inhibitors. It is thought that PEDF plays a protective role against atherosclerosis. Clinical studies have shown that serum levels of PEDF are increased in subjects with cardiovascular risk factors. The role of PEDF in cardiovascular disease is still controversial. The purpose of this study was to evaluate the associations between serum levels of PEDF and vascular function and structure. METHODS: We measured serum levels of PEDF, assessed vascular function by measurements of flow-mediated vasodilation (FMD) and nitroglycerine-induced vasodilation in the brachial artery, and measured brachial artery intima-media thickness (IMT) in 150 subjects who underwent health examinations. RESULTS AND CONCLUSIONS: Univariate regression analysis revealed that serum level of PEDF was significantly correlated with body mass index, high density lipoprotein cholesterol, glucose, FMD, nitroglycerine-induced vasodilation, and brachial artery IMT. Multivariate analysis revealed that serum levels of PEDF remained an independent predictor of nitroglycerine-induced vasodilation (beta=-0.20, P=0.02) and brachial artery IMT (beta=0.14, P=0.03) after adjustment of cardiovascular risk factors, while serum level of PEDF was not associated with FMD (beta=-0.02, P=0.79). These findings suggest that PEDF may be a factor directly associated with atherosclerosis. The serum level of PEDF may be a new biochemical marker of atherosclerosis.

PMID- 27716559 TI - Patients with calcific aortic stenosis exhibit systemic molecular evidence of ischemia, enhanced coagulation, oxidative stress and impaired cholesterol transport. AB - BACKGROUND: The most common valve diseases are calcific aortic stenosis (AS) and aortic regurgitation (AR). The former is characterized by thickening of valve leaflets followed by progressive calcification, which produces progressive aortic valve (AV) narrowing, increased pressure afterload on the left ventricle (LV) and subsequent LV hypertrophy. On the other hand, AR is due to malcoaptation of the valve leaflets with resultant diastolic reflux of blood from aorta back to the LV producing volume and pressure overload and progressive LV dilatation. In order to isolate the molecular mechanisms taking place during AS, we have used an integrated "-omic" approach to compare plasma samples from AS and from AR patients used as controls. The final purpose of this work is to find molecular changes in response to the calcification of the AV, diminishing the effects of the AV dysfunction. METHODS AND RESULTS: Using two-dimensional difference gel electrophoresis (2D-DIGE) and gas chromatography coupled to mass spectrometry (GC MS) in a cohort of 6 subjects, we have found differences in 24 protein spots and 19 metabolites, respectively. Among them, 7 proteins and 3 metabolites have been verificated by orthogonal techniques (SRM or turbidimetry): fibrinogen beta and gamma chain, vitronectin, apolipoprotein C-II, antithrombin III, haptoglobin, succinic acid, pyroglutamic acid and alanine. Classification according to their main function showed alterations related to coagulation, inflammation, oxidative stress, response to ischemia and lipid metabolism, defining 4 different molecular panels that characterize AS with high specificity and sensitivity. CONCLUSION: These results may facilitate management of these patients by making faster diagnostics of the disease and better understand these pathways for regulating its progression. PMID- 27716560 TI - The perception and acceptability of pre-slaughter and post-slaughter stunning for Halal production: The views of UK Islamic scholars and Halal consumers. AB - The importance of religious slaughter from economic, emotive and ethical viewpoints is significant. There are apparent economic benefits associated with trading in meats slaughtered according to religious traditions. Some religious authorities insist on the slaughter of animals without stunning, but this, according to many researchers, compromises animal welfare. We conducted a survey of Islamic scholars and Halal consumers, 66 scholars from 55 organisations and 314 consumers from 54 UK cities/towns were surveyed. Forty-nine scholars were interviewed through pre-arranged meetings, 17 surveyed online whilst all 314 consumers were either surveyed online or through the remote completion of copies of the questionnaire. Most of the scholars (>95%) (CI 86.9 to 98.4%) agreed that if an animal is stunned and then slaughtered by a Muslim and the method of stunning does not result in death, cause physical injury or obstruct bleed-out, the meat would be Halal and 53% (CI 47 to 58%) consumers also thought such meat would be Halal. PMID- 27716561 TI - Multiple antibiotic resistance genes distribution in ten large-scale membrane bioreactors for municipal wastewater treatment. AB - Wastewater treatment plants are thought to be potential reservoirs of antibiotic resistance genes. In this study, GeoChip was used for analyzing multiple antibiotic resistance genes, including four multidrug efflux system gene groups and three beta-lactamase genes in ten large-scale membrane bioreactors (MBRs) for municipal wastewater treatment. Results revealed that the diversity of antibiotic genes varied a lot among MBRs, but about 40% common antibiotic resistance genes were existent. The average signal intensity of each antibiotic resistance group was similar among MBRs, nevertheless the total abundance of each group varied remarkably and the dominant resistance gene groups were different in individual MBR. The antibiotic resistance genes majorly derived from Proteobacteria and Actinobacteria. Further study indicated that TN, TP and COD of influent, temperature and conductivity of mixed liquor were significant (P<0.05) correlated to the multiple antibiotic resistance genes distribution in MBRs. PMID- 27716562 TI - The excellent performance of nest-like oxygen-deficient Cu1.5Mn1.5O4 applied in activated carbon air-cathode microbial fuel cell. AB - This study investigated the performance of nano spinel nest-like oxygen-deficient Cu1.5Mn1.5O4 doping activated carbon (AC) as air cathode in microbial fuel cell (MFC). The Cu1.5Mn1.5O4 was synthesized via hydrothermal method and subsequent annealed. The maximum power density (MPD) of MFC with oxygen-deficient Cu1.5Mn1.5O4 modified cathode was 1928+/-18mWm-2, which was 1.53 times higher than the bare cathode. The electrochemical studies showed that Cu1.5Mn1.5O4 doping AC exhibited higher kinetic activity and lower resistance. The mechanism of oxygen reduction for the catalyst was a four electron pathway. The oxygen deficient of Cu1.5Mn1.5O4 played an important role in catalytic activity. So Cu1.5Mn1.5O4 would be an excellent promising catalyst for ORR in MFC. PMID- 27716563 TI - Interaction between common antibiotics and a Shewanella strain isolated from an enhanced biological phosphorus removal activated sludge system. AB - With increasing production and consumption, more antibiotics are discharged into wastewater treatment plants and generally cannot be sufficiently removed. Because of the complexities of biological treatment processes, the fates of antibiotics and their effects on microorganisms, particularly those involved in the phosphorus removal system, are still unclear. Here, a Shewanella strain was isolated from an enhanced biological phosphorus removal (EBPR) system and was found to have the ability to remove phosphorus (P) and chemical oxygen demand (CODcr). Antibiotics affected the Shewanella strain through metabolism of the three main intracellular polymers, altering the ability of the strain to remove P and CODcr. These effects varied with the structure and concentration of the antibiotics. The Shewanella strain removed cefalexin and amoxicillin by degradation or adsorption, producing 2-hydroxy-3-phenyl pyrazine from cefalexin. This study enabled the recognition of the effect and removal of antibiotics during wastewater treatment. PMID- 27716564 TI - Efficient conversion of pretreated brewer's spent grain and wheat bran by submerged cultivation of Hericium erinaceus. AB - Brewer's spent grain (BSG) and wheat bran (WB) are industrial byproducts that accumulate in millions of tons per year and are typically applied as animal feed. Since both byproducts show a great potential as substrates for fermentation, the approach developed in this study consists of utilizing these lignocellulosic byproducts for biomass production of the medicinal fungus Hericium erinaceus through submerged cultivation. To increase the biological efficiency of the bioconversion, acidic pretreatment was applied yielding a bioconversion of 38.6% for pretreated BSG and 34.8% for pretreated WB. This study shows that the complete degradation of (hemi)cellulose into monosaccharides was not required for an efficient bioconversion. The produced fungal biomass was applied in a second fermentation step to induce the secondary metabolite erinacine C production. Thus, biomass was produced as a functional food ingredient with erinacine C contents of 174.8mg/g for BSG and 99.3mg/g for WB based bioconversions. PMID- 27716565 TI - Performance and microbial community of a sequencing batch biofilm reactor treating synthetic mariculture wastewater under long-term exposure to norfloxacin. AB - The performance and microbial community of a sequencing batch biofilm reactor (SBBR) treating synthetic mariculture wastewater were evaluated under long-term exposure to norfloxacin (NFX) due to the overuse of antibiotics during the mariculture. The COD and NH4+-N removals had no distinct change at 0-6mgL-1 NFX and were inhibited at 6-35mgL-1 NFX. The specific oxygen uptake rate (SOUR), specific ammonium oxidation rate (SAOR), specific nitrite oxidation rate (SNOR) and specific nitrate reduction rate (SNRR) of the biofilm kept a decreasing tendency with the increase of NFX concentration from 0 to 35mgL-1. The presence of NFX promoted the microorganisms to secrete more extracellular polymeric substances (EPS) and affected the chemical compositions of EPS. The microbial richness and diversity showed some obvious variations at different NFX concentrations. The present results demonstrated that NFX inhibited the SBBR performance and should decrease the NFX dosage in the mariculture. PMID- 27716566 TI - Material and microbial changes during corn stalk silage and their effects on methane fermentation. AB - Silage efficiency is crucial for corn stalk storage in methane production. This study investigated characteristics of dynamic changes in materials and microbes during the silage process of corn stalks from the initial to stable state. We conducted laboratory-scale study of different silage corn stalks, and optimized silage time (0, 2, 5, 10, 20, and 30days) for methane production and the endogenous microbial community. The volatile fatty acid concentration increased to 3.00g/L on Day 10 from 0.42g/L on Day 0, and the pH remained below 4.20 from 5.80. The lactic acid concentration (44%) on Day 10 lowered the pH and inhibited the methane yield, which gradually decreased from 229mL/g TS at the initial state (Day 0, 2) to 207mL/g TS at the stable state (Day 10, 20, 30). Methanosaeta was the predominant archaea in both fresh and silage stalks; however, richness decreased from 14.11% to 4.75%. PMID- 27716567 TI - Growth in very preterm children: Head growth after discharge is the best independent predictor for cognitive outcome. AB - BACKGROUND: The contribution of growth parameters to the cognitive outcome of very low birth weight (VLBW)/very preterm (VP) infants is difficult to disentangle from other preterm-birth related factors. AIMS: We hypothesized that long-term cognitive and motor outcome of VLBW/VP infants is most strongly associated with growth in head circumference after hospital discharge. STUDY DESIGN: Single-centre prospective longitudinal study: anthropometric measures at different time points (birth, discharge, school-age). SUBJECTS: 136 VLBW/VP infants (<32weeks gestation/birth weight<1.500g). OUTCOME MEASURES: Cognitive and motor function (Kaufman Assessment Battery for Children; Movement Assessment Battery for Children) at school-age (6.7-10.0years, mean=8.2). RESULTS: In hierarchical multiple regression analyses, growth from birth to discharge significantly predicted cognitive outcome (weight: R2change=0.063, p=0.014; length: R2change=0.078, p=0.007; HC: R2change=0.050, p=0.030), as well as weight gain (R2change=0.096, p=0.001) and head growth (R2change=0.134, p<0.001) from discharge to school-age. While most growth parameters, especially those from birth to discharge, were significantly influenced by prenatal growth and immaturity related morbidity (R2=0.151 to 0.605, all p<=0.001), head growth after discharge was not (R2=0.029, p=0.461). CONCLUSIONS: Amongst all anthropometric measures, head growth between discharge and school-age is the best independent predictor for cognitive outcome in VLBW/VP infants. Determinants of head growth after discharge need further studies to identify targets for intervention. PMID- 27716570 TI - Ectopic pregnancy in simultaneous pancreas-kidney transplantation: A case report. AB - INTRODUCTION: We present a case report of ectopic pregnancy (EP) after simultaneous pancreas-kidney transplantation (SKPTx). PRESENTATION OF CASE: A 33 year-old female status post SKPTx suddenly got abdominal pain in the lower level. She had high human chorionic Gonadotropin test. Ultrasonography revealed that there was no fetus in the uterus but a dilated right fallopian tube, which strongly suggested ectopic pregnancy. An emergency operation was performed and a dilated right side uterine tube was found with adhesions to her transplant. Salpingectomy was performed and no visible injury to the pancreas was found by the procedure. Pathological evaluation showed ectopic pregnant fetus, and no pancreas dysfunction was observed after the operation. DISCUSSION: This is the first case and operation report of EP after SKPTx. We should consider various causes of acute abdomen as well as several pathological condition in the transplanted pancreas such as pancreatitis, abscess, and thrombosis in vessels in the organ. Moreover, transplanted pancreas in abdomen is easily misrecognized as adipose tissue and there is high risk that the organ to get injured surgically. CONCLUSION: EP should be included in the different diagnosis in SKPTx female patients who get acute abdominal pain. It is highly desirable that transplant surgeon is included in the operation team for EP of these patients. PMID- 27716568 TI - Plaque structural stress assessed by virtual histology-intravascular ultrasound predicts dynamic changes in phenotype and composition of untreated coronary artery lesions. AB - BACKGROUND AND AIMS: We aimed to determine whether finite element analysis (FEA) derived plaque structural stress (PSS) analysis can predict serial changes in atheroma volume, type, and tissue composition within a fibroatheroma-containing target segment. METHODS: Overall, 210 patients (210 untreated coronary artery lesions) underwent serial (baseline and 12-month follow-up) grayscale- and virtual histology (VH)-intravascular ultrasound (IVUS). Baseline PSS was assessed at the minimal lumen and at the maximum necrotic core (NC) sites. RESULTS: Overall, there was a significant decrease in %NC volume. The highest PSS tertile was associated with a smaller on-statin reduction in %NC volume (-1.55 +/- 1.03% in the highest vs. -5.18 +/- 1.12% in the lowest tertile, p = 0.025). Of the 115 lesions with baseline VH-thin cap fibroatheroma (TCFA), 36 (31%) showed persistent VH-TCFA at follow-up. Five of the 95 lesions with baseline thick-cap fibroatheroma evolved into VH-TCFA. Independent predictors of VH-TCFA at follow up (including persistent and new VH-TCFAs) were diabetes mellitus (odds ratio [OR] = 3.87, 95% CI = 1.58-9.47), a large MLA (OR = 1.39, 95% CI = 1.10-1.75), a greater percent atheroma volume (OR = 1.12, 95% CI = 1.05-1.19), VH-TCFA at baseline (OR = 8.01, 95% CI = 2.73-23.50), and a higher superficial PSS at the maximum NC site (OR = 1.02, 95% CI = 1.00-1.03), (all p < 0.05). Independent determinants of the serial change in %NC volume were high-sensitive C-reactive protein (beta = -2.79, 95% CI = -5.31 to -0.27), baseline %NC volume (beta = 0.70, 95% CI = -0.84 to -0.56), and superficial PSS at the maximum NC site (beta = 0.05, 95% CI = 0.01-0.08), (all p < 0.05). CONCLUSIONS: An elevated PSS was more likely associated with an increase in atheroma volume, a smaller on-statin reduction in %NC volumes, and the presence of VH-TCFA at follow-up. Morphologic and hemodynamic assessment by utilizing VH-IVUS may help understand and predict atherosclerotic progression. PMID- 27716571 TI - Pedicle screw position changing policy for nerve injury problems during screw insertion on thoracolumbar compression fractures. AB - INTRODUCTION: Intraoperative neurophysiologic monitoring (IONM) had important role related to the complications in spinal surgery. Somatosensory Evoked Potential (SSEP), Transcranial electric Muscle Evoked Potentials (tceMEPs), and free run EMG are parameters used to asses functional integrity of the nervous system during surgical procedures. Once warning signal was recognized, surgeon have to make a precise decision to overcome that problem. PRESENTATION OF CASE: We present a 47-year old male with back pain due to compression fracture of thoracic vertebra T12 and lumbar vertebrae L1. While stabilizing through the posterior approach on the T11 and 12 as well as L2 and L3, the SSEP monitor showed 50% reduction in the waveform as the pedicle screw was inserted at the left side of T12. The instrumentation was changed into vertebra thoracal T10, T11, and vertebrae lumbar L2, L3. The SSEP normalized and post operatively pain decreased. After surgery there was no neurological deficit. DISCUSSION: Acute trauma as a result of spine instrumentation may provoke significant edema, with mass effect causing neurophysiological dysfunction. Administration of intravenous steroid would do at this stage, followed by constant infusion for following 24 48h, may help ameliorating the mass effect and improving the neurologic outcome. Alternatively, immediate pedicle screw changing policy showed absolute recovery of nerve injury. CONCLUSION: Insertion of pedicle screw in spinal surgery has a risk of complication that could be treated by pedicle screw changing policy. PMID- 27716569 TI - Iron citrate reduces high phosphate-induced vascular calcification by inhibiting apoptosis. AB - BACKGROUND AND AIMS: High phosphate-induced vascular calcification (VC) and iron deficiency-induced anemia are two major contributors of cardiovascular morbidity and mortality in patients affected by chronic kidney disease (CKD). Since phosphate (Pi) control and iron replacement are common therapies in CKD, the aim of our study was to investigate the effect of iron on high Pi-induced VC in rat vascular smooth muscle cells (VSMCs). METHODS: We treated VSMCs with 5 mM Pi and iron citrate (Fe3+) to evaluate Ca deposition by Alizarin Red destaining, DNA fragmentation by ELISA, gene expression by RT-PCR and protein expression by Western blot. RESULTS: Pretreatment with Fe3+ prevents high Pi-induced calcium (Ca) deposition concentration-dependently, with 90.1% inhibition at 50 MUM (0.716 +/- 0.04 vs. 0.071 +/- 0.01, OD/mg protein; Pi vs. Pi + Fe3+, p < 0.01). We found that 50 MUM Fe3+ completely prevents high Pi-induced apoptosis measured as DNA fragmentation (1.51 +/- 0.08 vs. 1.03 +/- 0.06, Pi vs. Pi + Fe3+; p < 0.01), through the prevention of the downregulation of the pro-survival pathway GAS6/AXL. Moreover, Fe3+ stimulates autophagy, a protective phenomenon in VC, as demonstrated by electron microscopy and by autophagy flux detected by LC3IIbeta protein expression. Finally, high Pi-induced osteoblastic differentiation is partially affected by Fe3+, since BMP2 increase is prevented and OPN is enhanced, but RUNX2 increase and alpha-actin and SM22alpha decrease are not modified. Interestingly, the addition of Fe3+ at different time points after Pi challenge completely blocks the progression of Ca deposition. CONCLUSIONS: In conclusion, iron citrate inhibits high Pi-induced Ca deposition by prevention of apoptosis, induction of autophagy, and partially affecting osteoblastic differentiation. PMID- 27716572 TI - Trait and state rumination interact to prolong cortisol activation to psychosocial stress in females. AB - There is a growing realization that cognitive processes associated with stress coping, such as rumination and distraction, can impact the hypothalamic-pituitary adrenal-axis (HPA-axis). Yet, little is known about what aspects of the HPA-axis stress response (rate of activation, duration of activation, rate of recovery) is impacted by such cognitive processes. This study examines the impact of both ruminative trait tendencies and experimentally induced rumination on salivary cortisol responses to a social evaluative stress task. Participants (n=71) were exposed to the Trier Social Stress Test (TSST) and were then randomized to complete either a rumination or distraction task. Trait rumination was also assessed at baseline. Results showed no main effects of either trait rumination or experimental condition, but they interacted to predict the cortisol response. Specifically, participants high in trait rumination had prolonged duration of cortisol activation in the rumination condition, compared to those in the distraction condition. In contrast, cortisol responses of participants with low trait rumination did not differ by condition. Notably, our interaction effect was only significant in females. Our findings highlight the complex relationship between rumination and HPA-axis activity, suggesting an interaction of trait and state rumination in shaping HPA-axis responses to stress, and call attention to sex differences in this relationship. PMID- 27716573 TI - Oxytocin receptor gene variation rs53576 and alcohol abuse in a longitudinal population representative study. AB - BACKGROUND: Oxytocin is an important regulator of social relationships and has been implicated in development of substance use and addiction. We examined the association of a variance in the oxytocin receptor gene (OXTR rs53576 polymorphism) with alcohol use in a population-representative sample, and potential moderation by social functioning. METHODS: The analysis was carried out on the older birth cohort of the longitudinal Estonian Children Personality Behaviour and Health Study (ECPBHS), a cohort of initially 15 years old children (original n=593) recalled at ages 18 and 25. In all data collection waves the participants reported the frequency of consuming alcoholic beverages. Psychiatric interview was carried out at age 25 to assess the lifetime prevalence of substance use disorders. Adverse social interactions with teachers, classmates and family members were self-reported at ages 15 and 18. The minor (A) allele frequency was 0.37. RESULTS: Males homozygous for the A allele (suggested to be associated with less efficient oxytocinergic functioning) were more frequent alcohol consumers at ages 15 and 18 and also more likely to have had alcohol abuse or addiction by age 25 compared to male G allele carriers. Alcohol use was not associated with the OXTR genotype in females. Both male and female AA homozygotes who had reported less favourable relations with their teachers at age 15 more likely had alcohol use disorder. CONCLUSIONS: OXTR rs53576 polymorphism is associated with alcohol use and prevalence of alcohol use disorders in males, and this may be moderated by inferior interpersonal relationships. PMID- 27716574 TI - The effect of delphinidin on the mechanical properties of keratinocytes exposed to UVB radiation. AB - The usage of active compounds of dietary phytochemicals in prevention of UV induced skin diseases is increasingly gaining attention in the development of skin care products. The purpose of this study was to measure the influence of delphinidin (as a botanical agent) on the cell mechanical properties evaluated by the atomic force microscopy (AFM) technique in the immortalized human keratinocyte cell line (HaCaT) exposed to UVB radiation. The cells were treated with various doses of UVB radiation with and without pre and post-treatment with selected concentrations of delphinidin. The measurements of the elastic properties revealed that the exposure of HaCaT cells to high dose of the UVB radiation (100mJ/cm2) caused a decrease in the cell elastic modulus. It was accompanied by the decrease of metabolic activity, rearrangement of actin cytoskeleton and disappearance of the cell repair marker 53BP1. Both pre treatment and post-treatment with delphinidin at non-cytotoxic concentrations (5 or 10MUM), restored the elastic modulus of irradiated keratinocytes. A direct AFM analysis showed that the UVB-mediated decrease of the cell stiffness was restored more effectively when cells were treated with delphinidin after the UVB irradiation. The results demonstrate the regenerative effect of delphinidin on the mechanical properties of cells exposed to UVB radiation (100mJ/cm2), which may be due to antioxidant and inhibitory effect on matrix metalloproteinases activation. PMID- 27716575 TI - Sustained reduction of diversion and abuse after introduction of an abuse deterrent formulation of extended release oxycodone. AB - BACKGROUND: The development of abuse deterrent formulations is one strategy for reducing prescription opioid misuse and abuse. A putative abuse deterrent formulation of oxycodone extended release (OxyContin(r)) was introduced in 2010. Early reports demonstrated reduced abuse and diversion, however, an analysis of social media found 32 feasible methods to circumvent the abuse deterrent mechanism. We measured trends of diversion, abuse and street price of OxyContin to assess the durability of the initial reduction in abuse. METHODS: Data from the Poison Center Program, Drug Diversion Program, Opioid Treatment Program, Survey of Key Informant Patients Program and StreetRx program of the Researched Abuse, Diversion, and Addiction-Related Surveillance (RADARS(r)) System were used. The average quarterly rates of abuse and diversion for OxyContin were compared from before reformulation to the rate in second quarter 2015. Rates were adjusted for population using US Census data and drug availability. RESULTS: OxyContin abuse and diversion declined significantly each quarter after reformulation and persisted for 5 years. The rate of abuse of other opioid analgesics increased initially and then decreased, but to lesser extent than OxyContin. Abuse through both oral and non-oral routes of self-administration declined following the reformulation. The geometric mean difference in the street price of reformulated OxyContin was 36% lower than the reformulated product in the year after reformulation. DISCUSSION: Despite methods to circumvent the abuse deterrent mechanism, abuse and diversion of OxyContin decreased promptly following the introduction of a crush- and solubility- resistant formulation and continued to decrease over the subsequent 5 years.

AB - Miniature insects can be as small as a few hundred micrometres in size, making them among the smallest metazoan animals ever described. Yet, even at these length scales, they display remarkably sophisticated flight behaviours. For flight at such low Reynolds numbers, miniature insects have evolved biomechanical and neural adaptations that push the boundaries of what is possible in the realm of physics and neurobiology of flight. After several decades of relative dormancy, this question has recently been revisited by researchers working in diverse areas ranging from systematics and neurobiology to dispersal behaviours. In this review, I cover recent findings in this area, and point towards the many open questions that still remain unanswered.

AB - INTRODUCTION: Waterpipe smoking is addictive and its use is increasing globally among youth, yet little is known about the factors associated with nicotine dependence (ND) among waterpipe smokers. We investigated the factors associated with ND symptoms among a sample of Lebanese adolescents who smoke a waterpipe. METHODS: We collected data on factors potentially associated with ND (individual, socio-demographic, environmental, smoking patterns) among 160 current (past 30days) waterpipe smokers recruited from 8th and 9th school grades in Lebanon. We assessed the loss of autonomy over tobacco using the Hooked on Nicotine Checklist (HONC), ND using the International Classification of Diseases, 10th revision (ICD 10), and the number of ND symptoms endorsed. RESULTS: Depressive symptoms, lower self-esteem, and having at least one sibling who smokes a waterpipe were associated with the presence of ND symptoms, while enrollment in public schools, smoking a waterpipe >=30min per session, and believing that cigarette smoking is harmful to health were associated with endorsement of a higher number of ND symptoms. Smoking a whole waterpipe head without sharing and being in 9th grade in this study were associated with the presence and endorsement of a higher number of ND symptoms. CONCLUSIONS: We identified specific social and psychological characteristics, waterpipe smoking patterns, and beliefs about harmful effects of smoking associated with the presence of ND among adolescent waterpipe smokers. Considering these factors when planning policies to prevent ND among waterpipe smokers is warranted.

AB - Blooms of Karenia brevis (also called red tides) occur almost annually in the Gulf of Mexico. The health effects of the neurotoxins (i.e., brevetoxins) produced by this toxic dinoflagellate on marine turtles are poorly understood. Florida's Gulf Coast represents an important foraging and nesting area for a number of marine turtle species. Most studies investigating brevetoxin exposure in marine turtles thus far focus on dead and/or stranded individuals and rarely examine the effects in apparently "healthy" free-ranging individuals. From May July 2014, one year after the last red tide bloom, we collected blood from nesting loggerhead sea turtles (Caretta caretta) on Casey Key, Florida USA. These organisms show both strong nesting and foraging site fidelity. The plasma was analyzed for brevetoxin concentrations in addition to a number of health and immune-related parameters in an effort to establish sublethal effects of this toxin. Lastly, from July-September 2014, we collected unhatched eggs and liver and yolk sacs from dead-in-nest hatchlings from nests laid by the sampled females and tested these samples for brevetoxin concentrations to determine maternal transfer and effects on reproductive success. Using a competitive enzyme-linked immunosorbent assay (ELISA), all plasma samples from nesting females tested positive for brevetoxin (reported as ng brevetoxin-3[PbTx-3] equivalents [eq]/mL) exposure (2.1-26.7ng PbTx-3eq/mL). Additionally, 100% of livers (1.4-13.3ng PbTx 3eq/mL) and yolk sacs (1.7-6.6ng PbTx-3eq/mL) from dead-in-nest hatchlings and 70% of eggs (<1.0-24.4ng PbTx-3eq/mL) tested positive for brevetoxin exposure with the ELISA. We found that plasma brevetoxin concentrations determined by an ELISA in nesting females positively correlated with gamma-globulins, indicating a potential for immunomodulation as a result of brevetoxin exposure. While the sample sizes were small, we also found that plasma brevetoxin concentrations determined by an ELISA in nesting females significantly correlated with liver brevetoxin concentrations of dead-in-nest hatchlings and that brevetoxins could be related to a decreased reproductive success in this species. This study suggests that brevetoxins can still elicit negative effects on marine life long after a bloom has dissipated. These results improve our understanding of maternal transfer and sublethal effects of brevetoxin exposure in marine turtles.

AB - This study outlines the toxic effects of Quinalphos (QP), an organophosphrous insecticide on the development of zebrafish (Danio rerio) embryos, with special emphasis on toxicomorphomics and toxicokinetics of target enzyme, AChE. A range of concentrations was used to elucidate the median lethal concentration (LC50) of Quinalphos. Furthermore, embryos were exposed to two sub-lethal concentrations LC10 (0.66mg/L) and LC20 (1.12mg/L) along with a median lethal concentration (3.0mg/L) for 96h. Several morphological aberrations like lordosis, kyphosis, scoliosis, heart edema, breaks in the neuronal tube and underdeveloped facial parts were noticed, which were of concentration and time dependent. The QP has adequately hindered hatching process during the course of exposure which was upheld by the in silico docking studies with hatching enzyme, ZHE1. The length of hatchlings at 96h in LC50 concentration was significantly reduced to 47% compared to control. A significant pericardial effusion (5 to 16 fold) was observed in >90% of LC50 treated groups. Morphological changes in heart lead to the bradycardia, which ultimately leading to heart failure in some cases. The swimming behavior was significantly diminished in relation to the inhibition of AChE levels. From the in vitro kinetic studies, the kinetic constants Km, Vmax and inhibitory concentration Ki (4.45*10-5M) was determined which supported the competitive nature of QP. PMID- 27716581 TI - A study of temporal effects of the model anti-androgen flutamide on components of the hypothalamic-pituitary-gonadal axis in adult fathead minnows. AB - The aim of this study was to investigate temporal changes in the hypothalamic pituitary-gonadal (HPG) axis of fathead minnows (Pimephales promelas) treated with the model androgen receptor (AR) antagonist flutamide. Reproductively-mature fish were exposed in a flow-through test to analytically-confirmed concentrations of either 50 or 500MUg flutamide/L for 8 d, followed by an 8-d recovery period in clean water. Fish were sampled at 1, 2, 4 and 8days during each phase of the experiment. Flutamide (500MUg/L) caused significant reductions in relative gonad size of the females on day 8 of the exposure and day 1 of the recovery, and reduced expression of secondary sex characteristics in males during the exposure phase of the experiment. Ex vivo gonadal synthesis of testosterone in both sexes (and 17beta-estradiol in females) was reduced in the 500MUg/L treatment within 2 d of exposure; however, steroid synthesis returned to levels comparable to controls by the end of the exposure portion of the test. Ex vivo testosterone synthesis in males exposed to 50MUg flutamide/L was greater than in controls on days 4 and 8 of the exposure. Both the enhanced steroid production in the low treatment males, and return to control levels in the high treatment males and females during chemical exposure are indicative of a compensatory HPG response. One contributor to this response could be increased expression of genes responsible for enzymes involved in steroid synthesis; for example, transcripts for both cytochrome P450 side- chain cleavage and 11beta-hydroxysteroid dehydrogenase were significantly elevated in flutamide-exposed males. Overall, responses of the HPG axis in adult male and female fathead minnows exposed to flutamide were both dynamic and comparatively rapid during exposure and recovery. These observations have ramifications both for the development of short-term fish assays to detect endocrine-active chemicals, and the derivation of robust adverse outcome pathways for AR antagonists in fish.

AB - We have reported here, for the first time, to the best of our knowledge, a high nonlinear refractive index (n2e) of a natural pigment extracted from Hibiscus rosa-sinensis leaves by using spatial self-phase modulation technique (SSPM) with a low power CW He-Ne laser radiation at 632.8nm. It is found by UV-Vis absorption spectroscopic analysis that chlrophyll-a, chlrophyll-b and carotenoid are present in the pigment extract with 56%, 25% and 19%, respectively. The photoluminescence (PL) emission characteristics of the extracted samples have also been measured at room temperature as well as in the temperature range of 283-333K to investigate the effect of temperature on luminescent properties of the sample. By analyzing the SSPM experimental data, the nonlinear refractive index value of pigment extract has been determined to be 3.5*10-5cm2/W. The large nonlinear refractive index has been assigned due to asymmetrical structure, molecular reorientation and thermally induced nonlinearity in the sample. The presented results might open new avenues for the green and economical technique of syntheses of organic dyes with such a large nonlinear optical property. PMID- 27716583 TI - The thermochromic behavior of aromatic amine-SO2 charge transfer complexes. AB - The distinct thermochromism observed in solutions containing N,N-dimethylaniline (DMA) and N,N-diethylaniline (DEA) and SO2 was investigated by resonance Raman spectroscopy in a wide range of temperatures. The results indicate in addition to the charge transfer (CT) complexes DMA-SO2 and DEA-SO2, the presence of collision complexes involving the CT complexes and excess DMA and DEA molecules. The latter in fact is the chromophore responsible for the long wavelength absorption originating the color. The Raman signature of the collision complex was attributed to the distinct enhancement of a band at 1140cm-1 assigned to nus(SO2), in contrast to the same mode in the 1:1 complex at 1115cm-1. The intensity of such band, assigned to the collision complex is favored at high temperatures and depends on the steric hindrance associated to amines, as well as the SO2 molar fraction. Quantum chemical calculations based on time-dependent density functional theory (TDDFT) support the proposed interpretation. PMID- 27716579 TI - The transcription factor, Nuclear factor, erythroid 2 (Nfe2), is a regulator of the oxidative stress response during Danio rerio development. AB - Development is a complex and well-defined process characterized by rapid cell proliferation and apoptosis. At this stage in life, a developmentally young organism is more sensitive to toxicants as compared to an adult. In response to pro-oxidant exposure, members of the Cap'n'Collar (CNC) basic leucine zipper (b ZIP) transcription factor family (including Nfe2 and Nfe2-related factors, Nrfs) activate the expression of genes whose protein products contribute to reduced toxicity. Here, we studied the role of the CNC protein, Nfe2, in the developmental response to pro-oxidant exposure in the zebrafish (Danio rerio). Following acute waterborne exposures to diquat or tert-buytlhydroperoxide (tBOOH) at one of three developmental stages, wildtype (WT) and nfe2 knockout (KO) embryos and larvae were morphologically scored and their transcriptomes sequenced. Early in development, KO animals suffered from hypochromia that was made more severe through exposure to pro-oxidants; this phenotype in the KO may be linked to decreased expression of alas2, a gene involved in heme synthesis. WT and KO eleutheroembryos and larvae were phenotypically equally affected by exposure to pro-oxidants, where tBOOH caused more pronounced phenotypes as compared to diquat. Comparing diquat and tBOOH exposed embryos relative to the WT untreated control, a greater number of genes were up-regulated in the tBOOH condition as compared to diquat (tBOOH: 304 vs diquat: 148), including those commonly found to be differentially regulated in the vertebrate oxidative stress response (OSR) (e.g. hsp70.2, txn1, and gsr). When comparing WT and KO across all treatments and times, there were 1170 genes that were differentially expressed, of which 33 are known targets of the Nrf proteins Nrf1 and Nrf2. More specifically, in animals exposed to pro-oxidants a total of 968 genes were differentially expressed between WT and KO across developmental time, representing pathways involved in coagulation, embryonic organ development, body fluid level regulation, erythrocyte differentiation, and oxidation-reduction, amongst others. The greatest number of genes that changed in expression between WT and KO occurred in animals exposed to diquat at 2h post fertilization (hpf). Across time and treatment, there were six genes (dhx40, cfap70, dnajb9b, slc35f4, spi-c, and gpr19) that were significantly up-regulated in KO compared to WT and four genes (fhad1, cyp4v7, nlrp12, and slc16a6a) that were significantly down regulated. None of these genes have been previously identified as targets of Nfe2 or the Nrf family. These results demonstrate that the zebrafish Nfe2 may be a regulator of both primitive erythropoiesis and the OSR during development. PMID- 27716584 TI - Toxicity evaluation of selected ammonium-based ionic liquid forms with MCPP and dicamba moieties on Pseudomonas putida. AB - Combination of the hydrophilic herbicidal anion with hydrophobic, antimicrobial ammonium cation allows to obtain compounds in ionic liquid form with better properties then conventional herbicides. Both cation and anion can be modified by selection of herbicide and the length of alkyl chains in cation structure. However the knowledge of their potential toxic effects are still limited. Furthermore, the relation between hydrophobicity associated with the length of alkyl chains and toxicity for ionic liquids has not been thoroughly studied. Therefore we investigated toxic effects of herbicidal ionic liquid forms on growth inhibition, given as EC50, of the common soil bacterium Pseudomonas putida. We thereby concentrated on quaternary ammonium salts. Analyzed compounds were composed of dicamba or MCPP moieties and cation with various alkyl chain lengths (n = 6,8,10) We compared them with commercial herbicides, and ammonium based ionic liquids with neutral anion (Br-). In addition, cis-trans isomerisation of unsaturated membrane fatty acids in Pseudomonas putida was applied as the proxy for toxicity and membrane activity. We showed that toxicity increased with the length of alkyl chains. However, this correlation is only valid for six and eight carbon atom in alkyl chains, where for n = 10 the EC50 values rise by one order of magnitude. In our studies, the herbicidal ionic liquids [C10,C10,C1,C1N][MCPP] and [C10,C10,C1,C1N][dicamba] showed the lowest toxicity among analyzed quaternary ammonium salts and comparable toxicity with corresponding herbicides. No clear increase in toxicity could be followed by changing the anion moieties for ammonium-based ionic liquid forms. PMID- 27716585 TI - A review: Potential and challenges of biologically activated carbon to remove natural organic matter in drinking water purification process. AB - The use of biologically activated carbon (BAC) in drinking water purification is reviewed. In the past BAC is seen mostly as a polishing treatment. However, BAC has the potential to provide solution to recent challenges faced by water utilities arising from change in natural organic matter (NOM) composition in drinking water sources - increased NOM concentration with a larger fraction of hydrophilic compounds and ever increasing trace level organic pollutants. Hydrophilic NOM is not removed by traditional coagulation process and causes bacterial regrowth and increases disinfection by-products (DBPs) formation during disinfection. BAC can offer many advantages by removing hydrophilic fraction and many toxic and endocrine compounds which are not otherwise removed. BAC can also aid the other downstream processes if used as a pre-treatment. Major drawback of BAC was longer empty bed contact time (EBCT) required for an effective NOM removal. This critical review analyses the strategies that have been adopted to enhance the biological activity of the carbon by operational means and summarises the surface modification methods. To maximize the benefit of the BAC, a rethink of current treatment plant configuration is proposed. If the process can be expedited and adopted appropriately, BAC can solve many of the current problems. PMID- 27716586 TI - Removal of anionic pollutants by pine bark is influenced by the mechanism of retention. AB - The use of organic biosorbents for anion removal from water has been less studied than for cationic compounds. In this work, the removal capacity of pine bark for potential anionic pollutants (fluoride, phosphate, arsenate and dichromate) was assessed in column experiments, designed to study the process of transport. The results showed that pine bark has a very low retention capacity for phosphate, arsenate or fluoride, and in turn, very high for dichromate, with retention values close to 100% and less than 2% desorption of the adsorbed dichromate. The large differences observed between anions suggest that differences in the retention mechanism of each anion exist. In the case of phosphate and arsenate, electrostatic interactions with the mostly negatively charged functional groups of the pine bark determine the low retention capacity. Dichromate retention might proceed through reduction of chromium (VI) to chromium (III), what improves the efficiency of the removal. PMID- 27716587 TI - Removal of boron from wastewater: Evaluation of seven poplar clones for B accumulation and tolerance. AB - Boron (B) contamination of wastewater is a serious environmental and health problem, which has proved difficult to remediate. One potential approach is phytoremediation, i.e., the use of plants to extract B into the shoot systems, which can then be harvested and removed. The purpose of this study was to investigate the ability of seven hybrid poplar clones to accumulate and tolerate B at different levels of B and salinity. The clones were grown in quarter strength Hoagland's nutrient solution and exposed to four B treatments: 0.25, 25, 75 and 125 mg B L-1 in factorial combination with three salinity treatments: 0, 0.5 and 5 g L-1. Measurements were made of biomass (dry weight) and B concentrations (analyzed by inductively coupled plasma-optical emission spectroscopy) of plant tissues. The results showed that, with increasing level of B supply, the B concentrations in the shoot tissue of the poplar clones increased, while shoot biomass decreased. Comparison of the seven different poplar clones revealed that the clone designated 195-529 exhibited the greatest ability for B accumulation and tolerance. Generally, the 0.5 g L-1 level of salinity was beneficial for poplar growth and B removal, while the high salinity level of 5 g L-1 significantly inhibited poplar growth and B translocation from roots to shoots. Based on the results obtained with this hydroponic system, the clone 195-529 (P. trichocarpa * P. deltoides) is likely to be the most useful for the removal of B from B contaminated wastewater.

AB - OBJECTIVE: Post-operation of cervical decompression fusion and internal fixation (CDF) accelerated adjacent segment disc degeneration (ASD). It is not clear that whether instability of one single segmental accelerates the degeneration of adjacent segment disc. This study aims to explore the effect of cervical instability on the change of morphology and biochemistry in adjective segment (above) in the L5/6 cervical instability rabbit models. METHODS: Thirty-two mature New Zealand white rabbits (3000+/-250g) were randomly divided into two groups, control group (n=8) and model group (n=24). The animal models were established by destruction of partly annulus fibrosus and suction of nucleus pulposus. ASD was detected by X-ray after 4, 8 or 12 weeks surgery (8 model rabbits of each time). Animals were then euthanatized for cervical intervertebral disc tissue samples separation. Histomorphology, proteoglycan and collagen II of samples were detected. RESULTS: Histomorphology data showed that notochord cells were decreased in C4/5 cervical nucleus pulposus and were replaced by fibroblast like cells; a small amount cartilage cells were emerged; intervertebral disc anulus fibrosus becomes rough, disorganized, hyaline degeneration and pigmentation, in which contained fibrocartilage cells and cracks between the inner and outer layers. Proteoglycan content of nucleus pulposus was significantly decreased. Meanwhile, type II collagen of nucleus pulposus and annulus was also apparently reduced. CONCLUSION: Cervical instability can alter morphology and reduce the content of proteoglycan and collagen II in adjacent intervertebral disc, thereby contributes adjacent intervertebral disc degeneration. PMID- 27716590 TI - Therapeutic effects of Aloe spp. in traditional and modern medicine: A review. AB - Traditional medicine is a useful guide in medical sciences. In the Islamic Iranian traditional medicine, the medicinal properties of many plants have been mentioned that could be exploited in drug discovery. We aimed to explore the nature and properties of Aloe spp. As described in some major Islamic traditional texts including Ferdows al-Hekmah fi'l-Tibbe (The Paradise of Wisdom in Medicine), Al-Hawi fi'l-Tibb (Comprehensive Book of Medicine), Kamel al-Sanaat al Tibbyyah (Complete Book of the Medical Art), Al-Qanun fi'l-Tibb (Canon of Medicine), Zakhireh Kharazmshahi (Treasure of Kharazmshah), and Makhzan al-Adwiah (Drug Treasure), and assess the conformity of traditional medicine instructions with the findings of modern pharmacological studies. Gastrointestinal activities, hepato-protective properties, beneficial effects against skin problems such as wounds, injuries, and infective diseases are among the most frequently mentioned properties of Aloe spp. Several activities of Aloe spp. described in traditional medicine have been the subject of recent in vitro and in vivo studies as well as clinical trials. Owing to the positive findings, different preparations of Aloe spp. are now present in pharmaceutical markets such as Aloe cosmetic products. On the other hand, there are many traditional therapeutic effects of Aloe spp. which have not been studied and require confirmatory experimental or clinical investigations. It is hoped that the present study could stimulate further research on the unexplored aspects of the medicinal properties of Aloe spp. PMID- 27716591 TI - TACE combined with dendritic cells and cytokine-induced killer cells in the treatment of hepatocellular carcinoma: A meta-analysis. AB - Patients with hepatocellular carcinoma (HCC), a fatal cancer, have benefited significantly from TACE (transcatheter arterial chemoembolization) and immunotherapy treatments. Immunotherapy that includes dendritic cells and cytokine-induced killer cells (DC-CIK) in combination with TACE has been extensively applied in cases of HCC. Few decisive conclusions about these combined effects on the outcomes of HCC patients have been reached. Therefore, the present meta-analysis was performed to compare the efficacy of the combined usage of DC-CIK with TACE with a TACE therapy alone on the outcomes of HCC patients. Participants were enrolled in eight eligible trials. The efficiency and safety of TACE followed by DC-CIK immunotherapy (experimental group) and of TACE alone (control group) were compared. The meta-analysis results demonstrated that TACE plus DC-CIK immunotherapy is possibly superior to TACE alone in promoting a better overall response, for half-year, 1-year, and 2-year overall survival (OS), median overall survival (OS) and progression-free survival rates (PFS) in HCC patients. Further studies should be performed to confirm the effect of the combined therapy. PMID- 27716592 TI - Discovery and preclinical development of a novel prodrug conjugate of mesalamine with eicosapentaenoic acid and caprylic acid for the treatment of inflammatory bowel diseases. AB - Mesalamine (5-ASA) is one of the drugs indicated as first line therapy in ulcerative colitis for induction and maintenance of remission. Sulfasalazine and formulations of 5-ASA (pH-dependent and controlled release formulations) were developed to minimize the systemic absorption and maximize the delivery of the mesalamine to colon. Although, its efficacy and safety is well documented there are approximately 30% nonresponders to 5-ASA therapy. This necessitates the need for novel therapeutic options to improve the efficacy and safety of the currently available 5-ASA therapy. CLX-103 is a novel, patented prodrug molecular conjugate of mesalamine, eicosapentaenoic acid and caprylic acid designed to offer incremental benefits over the currently approved 5-ASA formulations. Results of in vitro and in vivo studies showed that CLX-103, was stable in simulated gastric fluid, but undergoes enzymatic hydrolysis in the small/large intestines to release the active moiety. Our data also showed that the active moiety is retained in the targeted intestinal tissues (ileum and colon) over a longer period of time in relation to sulfasalazine. The in vitro data supports the observed in vivo plasma kinetics of 5-ASA characterized by longer Tmax, low Cmax after the oral administration of CLX-103. Efficacy study of CLX-103 in acute dextran sodium sulfate (DSS) mouse colitis model showed improved potency measured as Disease Activity Index (DAI) and histological scores in the colon as compared to sulfasalazine. These findings indicate that CLX-103 could offer a differentiated drug product which is more efficacious and safer than the currently approved 5-ASA formulations in the treatment of inflammatory bowel diseases. PMID- 27716593 TI - Effects of macrophyte development on the oxygen metabolism of an urban river rehabilitation structure. AB - To compensate for fairway enlargements and the hydraulic impacts of navigation activity, an artificial rehabilitation structure was constructed in the urban, navigable River Spree in 2004. This wave-protected, shallow littoral zone proved to be highly effective in reducing vessel-induced waves and provided suitable conditions for the development of aquatic plants. However, in time it became less suitable for other aquatic organisms due to hypoxic conditions in late summer. This study aimed to comparatively calculate and analyze the oxygen balance of the rehabilitation structure and the main channel five years after the construction in 2009. In the rehabilitation structure, the production to respiration ratio ranged between 0.10 and 0.34 at the peak of vegetation density, while in the main channel in front of the rehabilitation structure it ranged between 0.67 and 0.86. Dense vegetation limited the water exchange and caused oxygen depletion. Thus, atmospheric oxygen input through the water surface and due to long-term water level changes became the most important supply processes for oxygen in the rehabilitation structure. Enhancing the oxygen supply to improve the suitability of the rehabilitation structure for other aquatic taxa requires an increase in water exchange with the main channel, e.g. by adaptively increasing the lateral connectivity. PMID- 27716594 TI - A label-free fluorescent direct detection of live Salmonella typhimurium using cascade triple trigger sequences-regenerated strand displacement amplification and hairpin template-generated-scaffolded silver nanoclusters. AB - The harm of Salmonella typhimurium (S. typhimurium) to public health mainly by the consumption of contaminated agricultural products or water stresses an urgent need for rapid detection methods to help control the spread of S. typhimurium. In this work, an intelligently designed sensor system took creative advantage of triple trigger sequences-regenerated strand displacement amplification and self protective hairpin template-generated-scaffolded silver nanoclusters (AgNCs) for the first time. In the presence of live S. typhimurium, single-stranded trigger sequences were released from aptamer-trigger sequences complex, initiating a branch migration to open the hairpin template I containing complementary scaffolds of AgNCs. Then the first strand displacement amplification was induced to produce numerous scaffolds of AgNCs and reporter strands which initiated a branch migration to open the hairpin template II containing complementary scaffolds of AgNCs. Then the second strand displacement amplification was induced to generate numerous scaffolds of AgNCs and trigger sequences which initiated the third branch migration and strand displacement amplification to produce numerous scaffolds of AgNCs and reporter strands in succession. Cyclically, the reproduction of the trigger sequences and cascade successive production of scaffolds were achieved successfully, forming highly fluorescent AgNCs, thus providing significantly enhanced fluorescent signals to achieve ultrasensitive detection of live S. typhimurium down to 50 CFU/mL with a linear range from 102 to 107CFU/mL. It is the first report on a fluorescent biosensor for detecting viable S. typhimurium directly, which can distinguish from heat denatured S. typhimurium. And it develops a new strategy to generate the DNA-scaffolds for forming AgNCs. PMID- 27716595 TI - Madness in the movies: An evaluation of the use of cinema to explore mental health issues in nurse education. AB - The research literature on the use of cinema in nurse education is relatively small. This study evaluates student nurses' learning experiences of a new undergraduate elective module called Madness in the Movies. Ethical approval was granted to conduct the study. Data were collected through an online survey and a social media discussion forum. The anonymous online survey responses were collated via Survey Monkey. Content analysis was conducted on the data from the Facebook discussion threads to understand, interpret and conceptualise the meanings from the data. All study participants agreed that their understanding of mental health issues was enriched, their attitudes and beliefs enhanced and their confidence to talk about mental health concerns increased significantly. This module provides a fruitful approach to encourage critical reflection on mental health issues in a safe environment that closely mirrors authentic practice experiences. The module facilitates the development of students' knowledge, values and attitudes in relation to person-centred mental healthcare. PMID- 27716596 TI - Assessment of Mastoid Function with Magnetic Resonance Imaging after Canal Wall Up Cholesteatoma Surgery. AB - OBJECTIVE: To use magnetic resonance imaging (MRI) to assess the extent of mastoid opacification after canal wall up (CWU) cholesteatoma surgery. MATERIALS AND METHODS: Thirty-five children in whom post-operative MRI had been obtained after CWU surgery. Cholesteatoma confined to the meso- and/or epi-tympanum was removed using a transcanal approach (n=18). More extensive disease required a combined approach tympanomastoidectomy (CAT, n=17). Mastoid opacification was assessed in both ears by a neuroradiologist blind to surgical details using an ordinal scale from 0 (no opacification) to 6 (completely opacified). The primary outcome measure was presence of normal mastoid ventilation, defined by evaluation of non-operative ears as a score <=2. The presence of normal ventilation, as well as the raw opacification scores, were compared according to type of cholesteatoma surgery: 1) transcanal, with no mastoidectomy and 2) CAT. RESULTS: Mastoid ventilation was normal in 18 post-operative ears (51%). There was no significant difference in the proportion of normally ventilated mastoids in the CAT (n=17) and transcanal (n=18) groups (p=0.318; Fisher's exact). However, mastoid opacification scores were significantly higher in the CAT group than in the transcanal group (p=0.036; Mann-Whitney U). CONCLUSION: The mastoid frequently fails to become normally ventilated after cholesteatoma surgery. Subgroup analysis suggests cortical mastoidectomy does not increase the likelihood of normal mastoid ventilation after CWU cholesteatoma surgery. MRI provides a non invasive tool to assess mastoid function, which contributes to the current debate on optimum surgical strategies for management of the mastoid in cholesteatoma surgery. Further research will determine whether this measure of mastoid health correlates with risk of recurrent cholesteatoma. PMID- 27716597 TI - Comparison of Hyaluronic Acid Fat Graft Myringoplasty, Fat Graft Myringoplasty and Temporal Fascia Techniques for the Closure of Different Sizes and Sites of Tympanic Membrane Perforations. AB - OBJECTIVE: To compare the efficacy of three different myringoplasty techniques, namely hyaluronic acid fat graft myringoplasty (HAFGM), fat graft myringoplasty (FGM), and temporal fascia for the closure of different sizes and sites of tympanic membrane perforations. MATERIALS AND METHODS: We retrospectively analyzed the medical records of patients who had undergone a type 1 tympanoplasty operation at our clinic between May 2007 and February 2013. The patients were divided into three groups depending on the patient's choice of technique as follows: Fat Graft Myringoplasty (FGM) (Group I), Hyaluronic Acid Fat Graft Myringoplasty (HAFGM) (Group II), and Temporalis Fascia (TF) (Group III). A total of 136 patients were included in the study, split in to the FGM (57 patients; 56.1% female; median age: 30 years), HAFGM (31 patients; 54.8 female; median age: 25 years), and TF (48 patients; 58.3% females; median age: 33 years) surgery technique groups. RESULTS: The patients were further divided into two groups, depending on the size of the perforation (small and large), and into three groups, depending on its location (anterior, inferior, and central). None of techniques provided a significantly better success rate in terms of perforation location (p>0.05). Also, none of the techniques provided a significantly better success rate in terms of perforation size (p>0.05). CONCLUSION: We propose using HAFGM for large perforations and FGM alone for small perforations. The TF technique is a successful and well-defined technique for tympanic membrane perforations; however, in our opinion, its technical difficulties make it a secondary choice, particularly for small-sized perforations.

AB - OBJECTIVE: The aims of our study were to evaluate the outcome of office-based paper patch grafting in tympanic membrane (TM) perforation regardless of the disease duration or etiology and to compare the clinical factors influencing the successful closure of perforation between the success and failure groups of paper patch myringoplasty. MATERIALS AND METHODS: This is a retrospective study of 114 patients that underwent paper patch myringoplasty in an outpatient setting (success group, 83 cases; failure group, 31 cases). Thirteen clinical factors with potential impact on the healing status of the TM were investigated: gender, age, laterality, etiology, duration of perforation, tinnitus, hearing loss, otorrhea, size and location of perforation, status of contralateral ear, ipsilateral findings of computed tomography, and duration of complete healing. The follow-up period was at least 1 year. RESULTS: The total success rate of paper patch grafting was 72.8%. The mean age of the failure group was significantly more higher than that of the success group. Significant differences in the etiology as well as in the history of otorrhea were found between the success and failure groups. There were no significant differences for any of the other factors between chronic and non-chronic perforations. CONCLUSION: The predictors of successful outcome were patient's age, etiology of perforation, and history of otorrhea. Clinicians can attempt paper patch myringoplasty first in younger patients, traumatic TM perforation cases, and in patients with no history of otorrhea. Paper patch grafting can also be considered before formal surgical myringoplasty in the case of small, dry, chronic TM perforations.

AB - OBJECTIVE: To assess the effectiveness of glass ionomer bone cement (GIBC) in lateral attic wall reconstruction after primary acquired attic cholesteatoma surgery. MATERIALS AND METHODS: This prospective study was conducted on twenty children collected from the ENT outpatient clinics of a secondary and tertiary hospital. All patients presented with chronic suppurative otitis media with cholesteatoma of the primary acquired attic type. All patients underwent intact canal wall mastoidectomy (ICWM) with a transcanal atticotomy to address primary cholesteatoma involving the attic and the supratubal recess. Removal of the incus with or without decapitation of the malleus depended on the extension of the pathology. GIBC was used to build up the lateral attic wall in all cases. Ossiculoplasty and tympanoplasty were performed according to the extent of disease. RESULTS: All patients had integrated skin covering the reconstructed attic wall with no signs of granulation tissue formation, canal wall edema, glass ionomer extrusion, or foreign body reaction on the 6th month, 1st year and 2nd year follow-up visits. Also, no persistent otorrhea was noted. The postoperative air-bone gap was significantly improved (p=0.007). CONCLUSION: GIBC could be considered as a reliable artificial material for reconstruction of the lateral attic wall after transmeatal atticotomy in ICWM, making it feasible to avoid cavity problems of canal wall down mastoidectomy, especially in children. PMID- 27716600 TI - Comparison of Videonystagmography and Audiological Findings after Stapedotomy; CO2 Laser vs Perforator. AB - OBJECTIVE: Various types of laser, microdrill, and perforator are effectively used in the surgical treatment of otosclerosis. However, they have certain disadvantages along with advantages. The aim of this study was to evaluate the effects of carbon dioxide (CO2) laser and perforator stapedotomy techniques on audiological outcomes and postoperative vestibular functions via videonystagmography (VNG). MATERIALS AND METHODS: This prospective and randomized clinical study was conducted in an academic tertiary medical center. Sixty-nine patients diagnosed with otosclerosis who underwent stapedotomy were enrolled in this study. Patients were divided into two groups based on the technique used in stapedotomy: CO2 laser and perforator. Postoperative hearing gain and VNG findings were the main outcome measures. Subsequently, the two study groups were compared for analysis. RESULTS: The preoperative air-bone gap was 32.7+/-8.9 decibel (dB) in the study population and it was improved to 12.9+/-8.4 dB after operation. There were no differences in VNG findings and vertigo symptoms between the laser and perforator groups at postoperative day 2. There was no significant gain difference regarding the air conduction, bone conduction, and air-bone gap between the two groups (p=0.294, p=0.57, and p=0.37, respectively). CONCLUSION: Both CO2 laser and perforator stapedotomy have successful audiological outcomes with no difference in postoperative vestibular disturbance. PMID- 27716601 TI - Diameter of the Medial Side of the Cochlear Aqueduct Is Narrower in Meniere's Disease: A Radiologic Analysis. AB - OBJECTIVE: This study aimed to measure the radiological dimensions of the cochlear aqueduct in Meniere's disease and in low-frequency hearing loss (LFHL) patients and control patients. MATERIALS AND METHODS: Groups of 26 patients (32 ears, including 6 with bilateral involvement) with Meniere's disease, 14 patients (18 ears) with LFHL, and 23 patients with unilateral chronic otitis media, as controls, were enrolled. For the measurements, high-resolution computed tomography (HRCT) of the temporal bone was performed. The cochlear aqueduct was evaluated for the following six parameters: medial opening (MO), petrous apex (PA), otic capsule (OC), lateral opening (LO), distance of the cochlear aqueduct (DC), and length of the cochlear aqueduct (LC). RESULTS: The PA, OC, DC, and LC were not significantly different between the groups. LO could not be measured because the LO was not visible in all cases. The MO diameter was narrower in the Meniere's disease group than in the LFHL group (p=0.001) and in the controls (p=0.035). When the dimensions of both ears were measured in patients with unilateral Meniere's disease, no statistically significant difference was found. CONCLUSION: Compared to LFHL and controls, the MO of the cochlear aqueduct was significantly smaller in the Meniere's disease group. PMID- 27716602 TI - Evaluation of the Vestibular System and Etiology in Children with Unilateral Sensorineural Hearing Loss. AB - OBJECTIVE: The aim of this study was to evaluate the vestibular system of children with unilateral sensorineural hearing loss (USNHL), investigate the etiological factors of USNHL and analyze whether a genetic predisposition exists. MATERIALS AND METHODS: Thirty-three children aged less than 18 years with USNHL, who visited the ear, nose, and throat (ENT) department between January 2004 and December 2012, were included in this study. Cases with conductive hearing loss were excluded from the study. The patients were subjected to etiologic, genetic, and ophthalmologic evaluation; radiologic imaging; electronystagmography (ENG); and vestibular evoked myogenic potential (VEMP) tests. The control group, which included 25 healthy children (13 males and 12 females), had undergone audiological assessment and were subjected to ENG and VEMP tests. RESULTS: All of the patients had severe-to-profound hearing loss. Mumps immunoglobulin G was positive in 22 (66.7%) of 33 patients. The 35delG mutation was not found in any of the patients. All of the patients underwent temporal computed tomography (CT) and magnetic resonance imaging (MRI). Inner ear anomaly was present in 51.5% of the patients. Overall, 21 of 31 ENG patients had canal paresis in the affected ear. The VEMP response was absent on the affected side in three patients. The n23 latency average of the patient group was longer than that of the control group. CONCLUSION: Because USNHL causes irreversible problems in children, early diagnosis and auditory rehabilitation are very important. As USNHL is accompanied by inner ear anomaly, children with USNHL should undergo temporal bone CT and MRI. To evaluate the vestibular system, ENG and VEMP are non-invasive and diagnostic tests. PMID- 27716603 TI - Do Vestibular-Evoked Myogenic Potential Abnormalities in Patients with Cochlear Implant Only Reflect Saccular Dysfunction? AB - OBJECTIVE: The objective of this study was to explore the usefulness of 1000-Hz tone burst (TB) stimuli for detecting cervical vestibular-evoked myogenic potential (cVEMP) abnormalities in patients with a cochlear implant (CI). MATERIALS AND METHODS: Thirty asymptomatic patients who received unilateral CI because of severe bilateral sensorineural hearing loss were assessed for cVEMP produced by TB stimuli at two frequencies (500 and 1000 Hz) in the airway. VEMPs were recorded when the devices were switched to the on (CI-on) and off (CI-off) positions. RESULTS: At the CI-on position, the surgical side (SS) 500-Hz response rates (15/30) were significantly higher than the SS 1000-Hz response rates (9/30) (p=0.031), while the non-operated control side (CS) 500-Hz response rates (20/30) were higher than the CS 1000-Hz response rates (18/30), but the difference was not significant (p=0.50). At the CI-on position, the SS 500-Hz response rates (15/30) were lower than the CS 500-Hz response rates (20/30), but the difference was not significant (p=0.063). However, the SS 1000-Hz response rates (9/30) were significantly lower than the CS 1000-Hz response rates (18/30) (p=0.004). When there was no significant difference between the 500-Hz amplitudes on either side, the SS 1000-Hz amplitudes were found to be significantly lower (p=0.04). CONCLUSION: CIs have the potential to cause mechanical damage and electrical stimulation to the vestibular system. Possible implant-mediated mechanical damage and electrical stimulation in the high-frequency region affecting the cVEMP response could be found by a 1000-Hz stimulus. PMID- 27716604 TI - Effect of a 4-Week Treatment with Cilostazol in Patients with Chronic Tinnitus: A Randomized, Prospective, Placebo-controlled, Double-blind, Pilot Study. AB - OBJECTIVE: The aim of this prospective, double-blind, randomized, placebo controlled study was to evaluate the efficacy of cilostazol, a selective phosphodiesterase 3 inhibitor, in patients with chronic tinnitus. MATERIALS AND METHODS: Adult patients of chronic tinnitus lasting more than 3 months were included. Fifty eligible patients were randomly assigned to either cilostazol or control (placebo) group. The study medication of oral 100-mg cilostazol and a matching placebo were used twice a day for 4 weeks. Subjective tinnitus severity was evaluated using the visual analog scale (VAS), tinnitus handicap inventory (THI), and Short-Form 36 health survey (SF-36) at baseline and at 2 and 4 weeks after study initiation. Changes in tinnitus pitch and loudness matching values were also analyzed. RESULTS: The improvement range in the VAS score was significantly greater in the cilostazol group than in the placebo group after 4 weeks' administration of cilostazol. The SF-36 subscales also showed improvement in quality of life in the physical component summary subscale, the aggregate subscale of the physical category. There were no significant improvements in the cilostazol group compared to the placebo group in the THI subscales and tinnitus characteristics of pitch and loudness matching values. Various degrees of headaches were experienced by 68% of patients in the cilostazol group. CONCLUSION: A 4-week administration of oral cilostazol in patients with chronic tinnitus may mitigate the severity of subjective tinnitus. PMID- 27716605 TI - Perception of Consonants in Speech-Shaped Noise among Young and Middle-Aged Adults. AB - OBJECTIVE: The present study was carried out to compare the consonant perception of young and middle-aged adults in quiet and noisy listening conditions. MATERIALS AND METHODS: Twenty-nine adults aged between 18 and 55 years old participated in the study, and were separated into two groups based on their age: Group I, comprising 15 young adults aged between 18 and 40 years old, and Group II, comprising 14 middle-aged adults aged between 41 and 55 years old. All the participants had normal hearing sensitivity in both ears. RESULTS: Consonant perception was better in favorable listening conditions for both young and middle aged adults. Comparison of the consonant identification scores of young and middle-aged adults showed significantly poorer scores among middle-aged adults in both quiet and noisy listening conditions. CONCLUSION: The findings of the present study reveal that middle-aged adults have small but significant consonant perception difficulties compared to younger adults in quiet and noisy listening conditions. PMID- 27716606 TI - The Effects of Silicone and Acrylic Ear Mold Materials on Outer Ear Canal Resonance Characteristics. AB - OBJECTIVES: The aim of this study is to investigate the effects of earmolds made of silicone and acrylic on outer ear canal resonance characteristics in terms of resonance frequency and amplitude measured in a hearing aid fitting. MATERIALS AND METHODS: Outer ear canal resonance frequencies and amplitudes in open ears and those measured with silicone and acrylic ear molds were obtained from 30 participants between the ages of 20 and 25 years (average age, 22.0 years; 18 females and 12 males) with a real ear gain measurement. To observe the changes depending on probe tube placement, test-retest variation was investigated in 10 participants before the study. RESULTS: There was no statistically significant difference between open ear canal resonance frequencies and those measured with silicone and acrylic earmolds (p>0.05). the silicone earmold resonance amplitude values were statistically significantly lower than the open ear canal resonance amplitudes when compared to those of the acrylic earmolds (p<0.05). CONCLUSION: Depending on the changes occurring in outer ear resonance features as a result of earmold materials used in hearing aid fittings, the application of earmolds should be done by experienced specialists. PMID- 27716607 TI - A Challenge for Cochlear Implantation: Duplicated Internal Auditory Canal. AB - Duplication of the internal auditory canal is an uncommon, congenital malformation that can be associated with sensorineural hearing loss owing to aplasia/hypoplasia of the vestibulocochlear nerve. Only 14 such cases have been reported to date. We report the case of a 13-month-old girl with bilateral, congenital, sensorineural hearing loss caused by narrow, duplicated internal auditory canals and discuss the challenges encountered in the diagnosis and treatment of this condition. PMID- 27716608 TI - Instability Due to Drug-Induced Vestibulotoxicity. AB - OBJECTIVE: The therapeutic use of ototoxic drugs is relatively common, particularly in patients with severe diseases. It is likely that disturbances of balance in these patients are underestimated by clinicians. MATERIALS AND METHODS: The purpose of this study was to identify drugs involved in the vestibulotoxic origin of instability in a group of 18 patients. RESULTS: Six patients showed both cochlear and vestibular damage, while 12 were affected only by posterior labyrinthine damage. Four groups of drugs were identified: antibiotics (nine patients), cytostatics (four), anti-tuberculosis medicinal products (three), and other drugs (two). Cytostatics were involved in many cases studied, a fact scarcely reported before. CONCLUSION: It is important to ensure an early diagnosis to prevent ototoxic effects induced by drugs. We propose that patients receiving potential ototoxic drugs undergo cochlear and vestibular assessments. Further, we recommend that patients with instability undergo vestibular rehabilitation.

AB - Chemical closure of tympanic membrane perforation is a commonly practiced office based otological procedure, which is labeled to be effective and safe. In this paper, we report a case of a young lady with disastrous complications following an attempt of chemical cauterization of her perforated tympanic membrane. PMID- 27716611 TI - Chronic Tuberculous Otomastoiditis: A Case Report. AB - Worldwide, tuberculosis is a widespread disease, with 8.7 million new cases occurring annually. Its etiologic agent, Mycobacterium tuberculosis, essentially causes pneumonia. However, this organism affects the middle ear in rare cases, accounting for 0.04-0.09% of all chronic middle ear otitis cases in Western countries. In this report, we describe the case of a young woman affected by tuberculosis of the middle ear. In our experience, empiric therapy was not beneficial. Adequate treatment was possible only after obtaining a specific diagnosis through a difficult process requiring surgical sampling for culture examination. We consider surgical sampling to be mandatory in all cases of chronic otitis media that do not respond to prolonged systemic and local therapies. PMID- 27716612 TI - Clinical audit project in undergraduate medical education curriculum: an assessment validation study. AB - Objectives: To evaluate the merit of the Clinical Audit Project (CAP) in an assessment program for undergraduate medical education using a systematic assessment validation framework. Methods: A cross-sectional assessment validation study at one medical school in Western Australia, with retrospective qualitative analysis of the design, development, implementation and outcomes of the CAP, and quantitative analysis of assessment data from four cohorts of medical students (2011- 2014). Results: The CAP is fit for purpose with clear external and internal alignment to expected medical graduate outcomes. Substantive validity in students' and examiners' response processes is ensured through relevant methodological and cognitive processes. Multiple validity features are built-in to the design, planning and implementation process of the CAP. There is evidence of high internal consistency reliability of CAP scores (Cronbach's alpha > 0.8) and inter-examiner consistency reliability (intra-class correlation>0.7). Aggregation of CAP scores is psychometrically sound, with high internal consistency indicating one common underlying construct. Significant but moderate correlations between CAP scores and scores from other assessment modalities indicate validity of extrapolation and alignment between the CAP and the overall target outcomes of medical graduates. Standard setting, score equating and fair decision rules justify consequential validity of CAP scores interpretation and use. Conclusions: This study provides evidence demonstrating that the CAP is a meaningful and valid component in the assessment program. This systematic framework of validation can be adopted for all levels of assessment in medical education, from individual assessment modality, to the validation of an assessment program as a whole. PMID- 27716613 TI - Lipid phosphatase SHIP2 functions as oncogene in colorectal cancer by regulating PKB activation. AB - Colorectal cancer (CRC) is the second most common cause of cancer-related death, encouraging the search for novel therapeutic targets affecting tumor cell proliferation and migration. These cellular processes are under tight control of two opposing groups of enzymes; kinases and phosphatases. Aberrant activity of kinases is observed in many forms of cancer and as phosphatases counteract such "oncogenic" kinases, it is generally assumed that phosphatases function as tumor suppressors. However, emerging evidence suggests that the lipid phosphatase SH2 domain-containing 5 inositol phosphatase (SHIP2), encoded by the INPPL1 gene, may act as an oncogene. Just like the well-known tumor suppressor gene Phosphatase and Tensin Homolog (PTEN) it hydrolyses phosphatidylinositol (3,4,5) triphosphate (PI(3,4,5)P3). However, unlike PTEN, the reaction product is PI(3,4)P2, which is required for full activation of the downstream protein kinase B (PKB/Akt), suggesting that SHIP2, in contrast to PTEN, could have a tumor initiating role through PKB activation. In this work, we investigated the role of SHIP2 in colorectal cancer. We found that SHIP2 and INPPL1 expression is increased in colorectal cancer tissue in comparison to adjacent normal tissue, and this is correlated with decreased patient survival. Moreover, SHIP2 is more active in colorectal cancer tissue, suggesting that SHIP2 can induce oncogenesis in colonic epithelial cells. Furthermore, in vitro experiments performed on colorectal cancer cell lines shows an oncogenic role for SHIP2, by enhancing chemoresistance, cell migration, and cell invasion. Together, these data indicate that SHIP2 expression contributes to the malignant potential of colorectal cancer, providing a possible target in the fight against this devastating disease. PMID- 27716614 TI - TNF induced cleavage of HSP90 by cathepsin D potentiates apoptotic cell death. AB - During apoptosis induction by TNF, the extrinsic and intrinsic apoptosis pathways converge at the lysosomal-mitochondrial interface. Earlier studies showed that the lysosomal aspartic protease Cathepsin D (CtsD) cleaves Bid to tBid, resulting in the amplification of the initial apoptotic cascade via mitochondrial outer membrane permeabilization (MOMP).The goal of this study was to identify further targets for CtsD that might be involved in activation upon death receptor ligation. Using a proteomics screen, we identified the heat shock protein 90 (HSP90) to be cleaved by CtsD after stimulation of U937 or other cell lines with TNF, FasL and TRAIL. HSP90 cleavage corresponded to apoptosis sensitivity of the cell lines to the different stimuli. After mutation of the cleavage site, HSP90 partially prevented apoptosis induction in U937 and Jurkat cells. Overexpression of the cleavage fragments in U937 and Jurkat cells showed no effect on apoptosis, excluding a direct pro-apoptotic function of these fragments. Pharmacological inhibition of HSP90 with 17AAG boosted ligand mediated apoptosis by enhancing Bid cleavage and caspase-9 activation. Together, we demonstrated that HSP90 plays an anti-apoptotic role in death receptor signalling and that CtsD-mediated cleavage of HSP90 sensitizes cells for apoptosis. These findings identify HSP90 as a potential target for cancer therapy in combination with death ligands (e.g. TNF or TRAIL). PMID- 27716615 TI - PITX2 and PANCR DNA methylation predicts overall survival in patients with head and neck squamous cell carcinoma. AB - BACKGROUND: Squamous cell carcinoma of the head and neck region (HNSCC) is a common malignant disease accompanied by a high risk of local or distant recurrence after curative-intent treatment. Biomarkers that allow for the prediction of disease outcome can guide clinicians with respect to treatment and surveillance strategies. Here, the methylation status of PITX2 and an adjacent lncRNA (PANCR) were evaluated for their ability to predict overall survival in HNSCC patients. RESULTS: PITX2 hypermethylation was associated with a better overall survival (hazard ratio, HR = 0.51, 95%CI: 0.35-0.74, p<0.001), while PANCR hypermethylation was significantly associated with an increased risk of death (HR = 1.64, 95%CI: 1.12-2.39, p=0.010). METHODS: Quantitative, methylation specific real-time PCR assays for PITX2 and PANCR were employed to measure bisulfite-converted DNA from formalin-fixed, paraffin-embedded (FFPE) tissues in a cohort of 399 patients with localized or locally advanced HNSCC who received curative-intent treatment (surgery with optional adjuvant radiochemotherapy or definite radiochemotherapy). CONCLUSIONS: PITX2 and PANCR methylation status were shown to be independent predictors for overall survival in HNSCC patients. Tissue based methylation testing could therefore potentially be employed to identify patients with a high risk for death who might benefit from a more radical or alternative treatment. PMID- 27716616 TI - Ran GTPase promotes cancer progression via Met recepto-rmediated downstream signaling. AB - It has been shown previously that cancer cells with an activated oncogenic pathway, including Met activation, require Ran for growth and survival.Here, we show that knockdown of Ran leads to a reduction of Met receptor expression in several breast and lung cancer cell lines. This, in turn suppressed HGF expression and the Met-mediated activation of the Akt pathway, as well as cell adhesion, migration, and invasion. In a cell line model where Met amplification has previously been shown to contribute to gefitinib resistance, Ran knockdown sensitized cells to gefitinib-mediated inhibition of Akt and ERK1/2 phosphorylation and consequently reduced cell proliferation. We further demonstrate that Met reduction-mediated by knockdown of Ran, occurs at the post transcriptional level, probably via a matrix metalloproteinase. Moreover, the level of immunoreactive Ran and Met are positively associated in human breast cancer specimens, suggesting that a high level of Ran may be a pre-requisite for Met overexpression. Interestingly, a high level of immunoreactive Ran dictates the prognostic significance of Met, indicating that the co-overexpression of Met and Ran may be associated with cancer progression and could be used in combination as a prognostic indicator. PMID- 27716617 TI - Matrix metalloproteinase-13 refines pathological staging of precancerous colorectal lesions. AB - An exact classification of precancerous stages of colorectal polyps might improve therapy and patients' outcome. Here we investigate the association between grade of dysplasia and Matrix metalloproteinase-13 (MMP-13) expression in 137 biopsies from patients with cancerous and non-cancerous colorectal adenomas. A reproducible staining procedure for histologic MMP-13 analysis in routinely fixed colorectal biopsy specimens has been established. A newly adopted immunoreactive scoring system for MMP-13 was demonstrated as reliable readout.The strength of the association between pathologic stage and immunoreactive MMP-13 scoring emphasizes its eligibility for diagnosis in precancerous colorectal lesions. PMID- 27716618 TI - Prognostic significance of AMPK in human malignancies: A meta-analysis. AB - BACKGROUND: AMPK is a well-investigated kinase mediating cellular metabolism and stress responses. However, its indicative role in survival prognosis remains ill defined. Therefore we performed this meta-analysis in order to clarify the prognostic impact of AMPK expression in human malignancies. METHODS: Literatures were retrieved via searching databases of PubMed, Web of Science, Embase and Cochrane Library. Studies comparing the prognostic significance between different AMPK levels among human malignancies were included into the pooled analysis. The statistical procedures were conducted by Review Manager 5.3 and the effect size was displayed by model of odds ratio. Subgroup analyses were additionally implemented to disclose the potential confounding elements. The outcome stability was examined by sensitivity analysis, and both Begg's test and Egger's test were utilized to detect the publication bias across the included studies. RESULTS: 21 retrospective cohorts were eventually obtained with a total sample-size of 9987 participants. Patients with higher AMPK expression had better outcomes of 3-year overall survival (P<0.0001), 5-year overall survival (P<0.0001), 10-year overall survival (P<0.0001), 3-year disease free survival (P<0.0001), 5-year disease free survival (P=0.002) and 10-year disease free survival (P=0.0004). Moreover, the majority of subgroup results also verified the favorably prognostic significance of AMPK over-expression. The outcome stability was confirmed by sensitivity analysis. Results of Begg's (P=0.76) and Egger's test (P=0.09) suggested that there was no publication bias within the included trials. CONCLUSIONS: Higher expression of AMPK significantly indicates better prognosis in human malignancies. PMID- 27716619 TI - Alpha fetoprotein antagonises benzyl isothiocyanate inhibition of the malignant behaviors of hepatocellular carcinoma cells. AB - Benzyl isothiocyanate (BITC) is a dietary isothiocyanate derived from cruciferous vegetables. Recent studies showed that BITC inhibited the growth of many cancer cells, including hepatocellular carcinoma (HCC) cells. Alpha-fetoprotein (AFP) is a important molecule for promoting progression of HCC, in the present investigation, we explore the influence of AFP on the role of BITC in the malignant behaviours of HCC cells, and the potential underlying mechanisms. We found thatBITC inhibited viability, migration, invasion and induced apoptosis of human liver cancer cell lines, Bel 7402(AFP producer) and HLE(non-AFP producer) cells in vitro. The role of BITC involve in promoting actived-caspase-3 and PARP 1 expression, and enhancing caspase-3 activity but decreasing MMP-2/9, survivin and CXCR4 expression. AFP antagonized the effect of BITC. This study suggests that BITC induced significant reductions in the viability of HCC cell lines. BITC may activate caspase-3 signal and inhibit the expression of growth- and metastasis-related proteins; AFP is an pivotal molecule for the HCC chemo resistance of BITC. PMID- 27716621 TI - Hypoxia-induced CCL28 promotes recruitment of regulatory T cells and tumor growth in liver cancer. AB - Tumor cells craft microenvironment to overcome growth disadvantages and adjust to escape the immunosurveillance during tumorigenesis and metastasis. The evolving adaption to the changing microenvironment is exemplified by the development of strategies to deal with hypoxia resulted from fast proliferation of the tumor cells. In this study, we found that hypoxia hepatocellular carcinoma (HCC) cells recruited Regulatory T cells (Tregs) and expressed more Chemokine (C-C motif) ligand 28 (CCL28). Deletion of CCL28 inhibited Treg recruitment. Furthermore, overexpression of CCL28 promoted tumor growth and Treg infiltration in vivo. Enhanced angiogenesis and VEGF expression was also observed. Moreover, inhibition of HIF1alpha reversed hypoxia-induced CCL28 upregulation. Taken together, our results demonstrate that HCC recruits Tregs to promote angiogenesis under hypoxic condition by upregulating CCL28 expression. These findings establish a link between Tregs and hypoxia in HCC growth and may provide a new potential therapeutic target for treating HCC. PMID- 27716620 TI - Circulating microRNAs found dysregulated in ex-exposed asbestos workers and pleural mesothelioma patients as potential new biomarkers. AB - Malignant pleural mesothelioma (MPM), a fatal cancer, is an occupational disease mostly affecting workers ex-exposed to asbestos fibers. The asbestos, a cancerogenic mineral of different chemical composition, was widely employed in western Countries in industrial manufactures of different types. MPM may arise after a long latency period, up to five decades. MPM is resistant to conventional chemo- and radio-therapies. Altogether, these data indicate that the identification of new and specific markers are of a paramount importance for an early diagnosis and treatment of MPM. In recent years, microRNAs expression was found dysregulated in patients, both in cancer cells and sera, affected by tumors of different histotypes, including MPM. Cell and circulanting microRNAs, found to be dysregulated in this neoplasia, were proposed as new biomarkers. It has been reported that circulating microRNAs are stable in biological fluids and could be employed as potential MPM biomarkers. In this investigation, circulating microRNAs (miR) from serum samples of MPM patients and workers ex-exposed to asbestos fibers (WEA) and healthy subjects (HS) were comparatively analyzed by microarray and RT-qPCR technologies. Our results allowed (i) to select MiR-3665, an endogenous stable microRNA, as the internal control to quantify in our analyses circulating miRNAs; to detect (ii) miR-197-3p, miR-1281 and miR 32-3p up regulated in MPM compared to HS; (iii) miR-197-3p and miR-32-3p up-regulated in MPM compared to WEA; (iv) miR-1281 up-regulated in both MPM and WEA compared to HS. In conclusion, three circulating up-regulated microRNAs, i.e. miR-197-3p, miR 1281 and miR-32-3p are proposed as potential new MPM biomarkers. PMID- 27716622 TI - Near infrared photoimmunotherapy with avelumab, an anti-programmed death-ligand 1 (PD-L1) antibody. AB - Near Infrared-Photoimmunotherapy (NIR-PIT) is a highly selective tumor treatment that employs an antibody-photo-absorber conjugate (APC). Programmed cell death protein-1 ligand (PD-L1) is emerging as a molecular target. Here, we describe the efficacy of NIR-PIT, using fully human IgG1 anti-PD-L1 monoclonal antibody (mAb), avelumab, conjugated to the photo-absorber, IR700DX, in a PD-L1 expressing H441 cell line, papillary adenocarcinoma of lung. Avelumab-IR700 showed specific binding and cell-specific killing was observed after exposure of the cells to NIR in vitro. In the in vivo study, avelumab-IR700 showed high tumor accumulation and high tumor-background ratio. Tumor-bearing mice were separated into 4 groups: (1) no treatment; (2) 100 MUg of avelumab-IR700 i.v.; (3) NIR light exposure only, NIR light was administered; (4) 100 MUg of avelumab-IR700 i.v., NIR light was administered. Tumor growth was significantly inhibited by NIR-PIT treatment compared with the other groups (p < 0.001), and significantly prolonged survival was achieved (p < 0.01 vs other groups). In conclusion, the anti-PD-L1 antibody, avelumab, is suitable as an APC for NIR-PIT. Furthermore, NIR-PIT with avelumab IR700 is a promising candidate of the treatment of PD-L1-expressing tumors that could be readily translated to humans. PMID- 27716623 TI - Low pH impairs complement-dependent cytotoxicity against IgG-coated target cells. AB - Local acidosis is a common feature of allergic, vascular, autoimmune, and cancer diseases. However, few studies have addressed the effect of extracellular pH on the immune response. Here, we analyzed whether low pH could modulate complement dependent cytotoxicity (CDC) against IgG-coated cells. Using human serum as a complement source, we found that extracellular pH values of 5.5 and 6.0 strongly inhibit CDC against either B lymphoblast cell lines coated with the chimeric anti CD20 mAb rituximab or PBMCs coated with the humanized anti-CD52 mAb alemtuzumab. Suppression of CDC by low pH was observed either in cells suspended in culture medium or in whole blood assays. Interestingly, not only CDC against IgG-coated cells, but also the activation of the complement system induced by the alternative and lectin pathways was prevented by low pH. Tumor-targeting mAbs represent one of the most successful tools for cancer therapy, however, the use of mAb monotherapy has only modest effects on solid tumors. Our present results suggest that severe acidosis, a hallmark of solid tumors, might impair complement mediated tumor destruction directed by mAb.

AB - Trans-resveratrol suppresses glioblastoma growth in vitro, but its effects on intracranial glioblastomas remain untested. Resveratrol crosses the blood-brain barrier, and lumbar puncture (LP) greatly increases its bioavailability in rat brains; therefore, we investigated the effectiveness of LP-administered resveratrol on orthotopic rat glioblastomas. Twenty-four tumor-bearing rats were separated into two groups: Group 1 receiving 100 MUl saline containing 0.3% DMSO and Group 2 receiving 100 MUl resveratrol (300 MUM). Treatments started 3 days after transplantation in 2-day intervals until death. Intracranial drug availabilities, tumor sizes, average life spans and the impacts on STAT3 signaling, apoptosis and autophagy rates were evaluated. MRI imaging revealed that average tumor size in the LP group (495.8 +/- 22.3 mm2) was smaller than the control groups (810.3 +/- 56.4 mm2; P<0.05). The mean survival time in the LP group (22.2 +/- 2.1 d) was longer than control animals (16.0 +/- 1.8 d; P<0.05). LP resveratrol-treated glioblastomas showed less Cyclin D1 staining, enhanced autophagy with up-regulated LC3 and Beclin1 expression, and widely distributed apoptotic foci around tumor capillaries with suppressed STAT3 expression and nuclear translocation. In conclusion, LP-delivered resveratrol efficiently inhibited orthotopic rat glioblastoma growth by inactivating STAT3 signaling and enhancing autophagy and apoptosis.

AB - The hexosamine biosynthetic pathway (HBP) requires two key nutrients glucose and glutamine for O-linked N-acetylglucosamine (O-GlcNAc) cycling, a post translational protein modification that adds GlcNAc to nuclear and cytoplasmic proteins. Increased GlcNAc has been linked to regulatory factors involved in cancer cell growth and survival. However, the biological significance of GlcNAc in diffuse large B-cell lymphoma (DLBCL) is not well defined. This study is the first to show that both the substrate and the endpoint O-GlcNAc transferase (OGT) enzyme of the HBP were highly expressed in DLBCL cell lines and in patient tumors compared with normal B-lymphocytes. Notably, high OGT mRNA levels were associated with poor survival of DLBCL patients. Targeting OGT via small interference RNA in DLBCL cells inhibited activation of GlcNAc, nuclear factor kappa B (NF-kappaB), and nuclear factor of activated T-cells 1 (NFATc1), as well as cell growth. Depleting both glucose and glutamine in DLBCL cells or treating them with an HBP inhibitor (azaserine) diminished O-GlcNAc protein substrate, inhibited constitutive NF-kappaB and NFATc1 activation, and induced G0/G1 cell-cycle arrest and apoptosis. Replenishing glucose-and glutamine-deprived DLBCL cells with a synthetic glucose analog (ethylenedicysteine-N-acetylglucosamine [ECG]) reversed these phenotypes. Finally, we showed in both in vitro and in vivo murine models that DLBCL cells easily take up radiolabeled technetium-99m-ECG conjugate. These findings suggest that targeting the HBP has therapeutic relevance for DLBCL and underscores the imaging potential of the glucosamine analog ECG in DLBCL. PMID- 27716626 TI - Secretory leukoprotease inhibitor is required for efficient quercetin-mediated suppression of TNFalpha secretion. AB - Dendritic cells (DCs) are professional antigen presenting cells (APCs) that in response to microbial infections generate long-lasting adaptive immune response. Following microbial uptake, DCs undergo a cascade of cellular differentiation that ultimately leads to "mature" DCs. Mature DCs produce a variety of inflammatory cytokines, including tumor necrosis factor-alpha (TNFbeta) a key cytokine for the inflammatory cascade. In numerous studies, polyphenols, including quercetin, demonstrated their ability to suppress TNFalpha secretion and protect from the onset of chronic inflammatory disorders. We show that murine bone marrow derived DCs express Slpi following quercetin exposure. Slpi is known to suppress LPS mediated NFkappaB activation, thus, it was hypothesized that its expression could be the key step for polyphenol induced inflammatory suppression. Slpi-KO DCs poorly respond to quercetin administration failing to reduce TNFalpha secretion in response to quercetin exposure. Supernatant from quercetin exposed DCs could also reduce LPS-mediated TNFalpha secretion by unrelated DCs, but this property is lost using an anti-Slpi antibody. In vivo, oral administration of quercetin is able to induce Slpi expression. Human biopsies from inflamed tract of the intestine reveal the presence of numerous SLPI+ cells and the expression level could be further increased by quercetin administration. We propose that quercetin induces Slpi expression that in turn reduces the inflammatory response. Our data encourages the development of nutritional strategies to improve the efficiency of current therapies for intestinal chronic inflammatory syndrome and reduce the risks of colorectal cancer development.

AB - HER2/ERBB2 amplification/overexpression determines the eligibility of breast cancer patients to HER2-targeted therapy. This study evaluates the agreement between ERBB2 copy number assessment by fluorescence in situ hybridization, a standard method recommended by the American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP), and newly available DNA extraction-based methods. A series of n=29 formalin-fixed paraffin-embedded breast cancers were subjected to ERBB2 copy number assessment by fluorescence in situ hybridization (FISH, Vysis, Abbott). Following macrodissection of invasive breast cancer tissue and DNA extraction, ERBB2 copy number was also determined by molecular inversion probe array analysis (MIP, OncoScan, Affymetrix) and next generation sequencing combined with normalized amplicon coverage analysis (NGS/NAC, AmpliSeq, Ion Torrent). ERBB2 copy number values obtained by MIP or NGS/NAC were tightly correlated with ERBB2 copy number values obtained by conventional FISH (rs = 0.940 and rs = 0.894, P < 0.001). Using ASCO/CAP guideline-conform thresholds for categorization of breast cancers as HER2-negative, equivocal or positive, nearly perfect concordance was observed for HER2 classification by FISH and MIP (93% concordant classifications, kappa = 0.87). Substantial concordance was observed for FISH and NGS/NAC (83% concordant classifications, kappa = 0.62). In conclusion, MIP facilitates precise ERBB2 copy number detection and should be considered as an ancillary method for clinical HER2 testing. PMID- 27716628 TI - A comparison of different bioinks for 3D bioprinting of fibrocartilage and hyaline cartilage. AB - Cartilage is a dense connective tissue with limited self-repair capabilities. Mesenchymal stem cell (MSC) laden hydrogels are commonly used for fibrocartilage and articular cartilage tissue engineering, however they typically lack the mechanical integrity for implantation into high load bearing environments. This has led to increased interested in 3D bioprinting of cell laden hydrogel bioinks reinforced with stiffer polymer fibres. The objective of this study was to compare a range of commonly used hydrogel bioinks (agarose, alginate, GelMA and BioINKTM) for their printing properties and capacity to support the development of either hyaline cartilage or fibrocartilage in vitro. Each hydrogel was seeded with MSCs, cultured for 28 days in the presence of TGF-beta3 and then analysed for markers indicative of differentiation towards either a fibrocartilaginous or hyaline cartilage-like phenotype. Alginate and agarose hydrogels best supported the development of hyaline-like cartilage, as evident by the development of a tissue staining predominantly for type II collagen. In contrast, GelMA and BioINKTM (a PEGMA based hydrogel) supported the development of a more fibrocartilage-like tissue, as evident by the development of a tissue containing both type I and type II collagen. GelMA demonstrated superior printability, generating structures with greater fidelity, followed by the alginate and agarose bioinks. High levels of MSC viability were observed in all bioinks post-printing (~80%). Finally we demonstrate that it is possible to engineer mechanically reinforced hydrogels with high cell viability by co-depositing a hydrogel bioink with polycaprolactone filaments, generating composites with bulk compressive moduli comparable to articular cartilage. This study demonstrates the importance of the choice of bioink when bioprinting different cartilaginous tissues for musculoskeletal applications. PMID- 27716629 TI - Ethical considerations in the translation of regenerative biofabrication technologies into clinic and society. AB - Biofabrication technologies have the potential to improve healthcare by providing highly advanced and personalized biomedical products for research, treatment and prevention. As the combining of emerging techniques and integrating various biological and synthetic components becomes increasingly complex, it is important that relevant stakeholders anticipate the translation of biofabricated 3D tissue products into patients and society. Ethics is sometimes regarded as a brake on scientific progress, yet from our perspective, ethics in parallel with research anticipates societal impacts of emerging technologies and stimulates responsible innovation. For the ethical assessment, the biofabrication field benefits from similarities to regenerative medicine and an increasing ethical awareness in the development of tissue-engineered products. However, the novelty of the technology itself, the increase in attainable structural complexity, and the potential for automation and personalization are distinguishing facets of biofabrication that call for a specific exploration of the ethics of biofabrication. This review aims to highlight important points of existing ethical discussions, as well as to call attention to emerging issues specific to 3D biofabrication in bench and bedside research and the translation to society. PMID- 27716630 TI - Evaluation of 3D printed PCL/PLGA/beta-TCP versus collagen membranes for guided bone regeneration in a beagle implant model. AB - Here, we compared 3D-printed polycaprolactone/poly(lactic-co-glycolic acid)/beta tricalcium phosphate (PCL/PLGA/beta-TCP) membranes with the widely used collagen membranes for guided bone regeneration (GBR) in beagle implant models. For mechanical property comparison in dry and wet conditions and cytocompatibility determination, we analyzed the rate and pattern of cell proliferation of seeded fibroblasts and preosteoblasts using the cell counting kit-8 assay and scanning electron microscopy. Osteogenic differentiation was verified using alizarin red S staining. At 8 weeks following implantation in vivo using beagle dogs, computed tomography and histological analyses were performed after sacrifice. Cell proliferation rates in vitro indicated that early cell attachment was higher in collagen than in PCL/PLGA/beta-TCP membranes; however, the difference subsided by day 7. Similar outcomes were found for osteogenic differentiation, with approximately 2.5 times greater staining in collagen than PCL/PLGA/beta-TCP, but without significant difference by day 14. In vivo, bone regeneration in the defect area, represented by new bone formation and bone-to-implant contact, paralleled those associated with collagen membranes. However, tensile testing revealed that whereas the PCL/PLGA/beta-TCP membrane mechanical properties were conserved in both wet and dry states, the tensile property of collagen was reduced by 99% under wet conditions. Our results demonstrate in vitro and in vivo that PCL/PLGA/beta-TCP membranes have similar levels of biocompatibility and bone regeneration as collagen membranes. In particular, considering that GBR is always applied to a wet environment (e.g. blood, saliva), we demonstrated that PCL/PLGA/beta-TCP membranes maintained their form more reliably than collagen membranes in a wet setting, confirming their appropriateness as a GBR membrane. PMID- 27716631 TI - Bioactivity of dexamethasone-releasing coatings on polymer/magnesium composites. AB - We developed biodegradable polymeric coatings loaded with increasing amounts of dexamethasone on composites based on polylactic acid and Mg particles for bone repair. Incorporation of Mg particles into the polymeric matrix improves the compressive behaviour of the polymer. Mg-containing composites release Mg2+ ions into the culture medium and improve mesenchymal stem cell (MSC) viability, enhance their osteogenic potential and promote the release of angiogenic factors. Dexamethasone-loaded coatings deposited on composites delay Mg2+ ion dissolution while releasing controlled amounts of the drug, which are highly dependent on initial payload. Release kinetic of dexamethasone from the coatings exhibits a fast initial release of the drug followed by a slower secondary release. Bioactivity of the released dexamethasone was explored by monitoring dose dependent responses of MSCs and macrophages. Biological effects exerted by the released drug are similar to those observed in cells treated with solutions of the glucocorticoid, indicating that the method employed for inclusion of dexamethasone into the coatings does not impair its bioactive behaviour. Culturing MSCs on dexamethasone-releasing coatings enhances extracellular matrix production and initial induction to osteogenic commitment as a function of drug payload. Dexamethasone incorporated into the coatings presents anti-inflammatory activity, as shown by the decrease in the production of cytokines and angiogenic factors by macrophages and MSCs. Deposition of dexamethasone-releasing coatings on polymer/Mg composites appears to be a promising approach to delay composite degradation at the early stage of implantation and may be useful to attenuate inflammation and adverse foreign body reactions. PMID- 27716632 TI - Characterization of Al2O3 optically stimulated luminescence films for 2D dosimetry using a 6 MV photon beam. AB - This work evaluates the dosimetric properties of newly developed optically stimulated luminescence (OSL) films, fabricated with either Al2O3:C or Al2O3:C,Mg, using a prototype laser scanning reader, a developed image reconstruction algorithm, and a 6 MV therapeutic photon beam. Packages containing OSL films (Al2O3:C and Al2O3:C,Mg) and a radiochromic film (Gafchromic EBT3) were irradiated using a 6 MV photon beam using different doses, field sizes, with and without wedge filter. Dependence on film orientation of the OSL system was also tested. Diode-array (MapCHECK) and ionization chamber measurements were performed for comparison. The OSLD film doses agreed with the MapCHECK and ionization chamber data within the experimental uncertainties (<2% at 1.5 Gy). The system background and minimum detectable dose (MDD) were <0.5 mGy, and the dose response was approximately linear from the MDD up to a few grays (the linearity correction was <10% up to ~2-4 Gy), with no saturation up to 30 Gy. The dose profiles agreed with those obtained using EBT3 films (analyzed using the triple channel method) in the high dose regions of the images. In the low dose regions, the dose profiles from the OSLD films were more reproducible than those from the EBT3 films. We also demonstrated that the OSL film data are independent on scan orientation and field size over the investigated range. The results demonstrate the potential of OSLD films for 2D dosimetry, particularly for the characterization of small fields, due to their wide dynamic range, linear response, resolution and dosimetric properties. The negligible background and potential simple calibration make these OSLD films suitable for remote audits. The characterization presented here may motivate further commercial development of a 2D dosimetry system based on the OSL from Al2O3:C or Al2O3:C,Mg. PMID- 27716633 TI - 3D printing of photocurable poly(glycerol sebacate) elastomers. AB - Three-dimensional (3D) printed scaffolds have great potential in biomedicine; however, it is important that we are able to design such scaffolds with a range of diverse properties towards specific applications. Here, we report the extrusion-based 3D printing of biodegradable and photocurable acrylated polyglycerol sebacate (Acr-PGS) to fabricate scaffolds with elastic properties. Two Acr-PGS macromers were synthesized with varied molecular weights and viscosity, which were then blended to obtain photocurable macromer inks with a range of viscosities. The quality of extruded and photocured scaffolds was dependent on the initial ink viscosity, with flow of printed material resulting in a loss of structural resolution or sample breaking observed with too low or too high viscosity inks, respectively. However, scaffolds with high print resolution and up to ten layers were fabricated with an optimal ink viscosity. The mechanical properties of printed scaffolds were dependent on printing density, where the scaffolds with lower printing density possessed lower moduli and failure properties than higher density scaffolds. The 3D printed scaffolds supported the culture of 3T3 fibroblasts and both spreading and proliferation were observed, indicating that 3D printed Acr-PGS scaffolds are cytocompatible. These results demonstrate that Acr-PGS is a promising material for the fabrication of elastomeric scaffolds for biomedical applications. PMID- 27716634 TI - Stochastic simulation tools and continuum models for describing two-dimensional collective cell spreading with universal growth functions. AB - Two-dimensional collective cell migration assays are used to study cancer and tissue repair. These assays involve combined cell migration and cell proliferation processes, both of which are modulated by cell-to-cell crowding. Previous discrete models of collective cell migration assays involve a nearest neighbour proliferation mechanism where crowding effects are incorporated by aborting potential proliferation events if the randomly chosen target site is occupied. There are two limitations of this traditional approach: (i) it seems unreasonable to abort a potential proliferation event based on the occupancy of a single, randomly chosen target site; and, (ii) the continuum limit description of this mechanism leads to the standard logistic growth function, but some experimental evidence suggests that cells do not always proliferate logistically. Motivated by these observations, we introduce a generalised proliferation mechanism which allows non-nearest neighbour proliferation events to take place over a template of [Formula: see text] concentric rings of lattice sites. Further, the decision to abort potential proliferation events is made using a crowding function, f(C), which accounts for the density of agents within a group of sites rather than dealing with the occupancy of a single randomly chosen site. Analysing the continuum limit description of the stochastic model shows that the standard logistic source term, [Formula: see text], where lambda is the proliferation rate, is generalised to a universal growth function, [Formula: see text]. Comparing the solution of the continuum description with averaged simulation data indicates that the continuum model performs well for many choices of f(C) and r. For nonlinear f(C), the quality of the continuum-discrete match increases with r. PMID- 27716635 TI - Roberts Prize for the best paper published in 2015. PMID- 27716636 TI - Evaluation of amorphous magnesium phosphate (AMP) based non-exothermic orthopedic cements. AB - This paper reports for the first time the development of a biodegradable, non exothermic, self-setting orthopedic cement composition based on amorphous magnesium phosphate (AMP). The occurrence of undesirable exothermic reactions was avoided through using AMP as the solid precursor. The phenomenon of self-setting with optimum rheology is achieved by incorporating a water soluble biocompatible/biodegradable polymer, polyvinyl alcohol (PVA). Additionally, PVA enables a controlled growth of the final phase via a biomimetic process. The AMP powder was synthesized using a precipitation method. The powder, when in contact with the aqueous PVA solution, forms a putty resulting in a nanocrystalline magnesium phosphate phase of cattiite. The as-prepared cement compositions were evaluated for setting times, exothermicity, compressive strength, biodegradation, and microstructural features before and after soaking in SBF, and in vitro cytocompatibility. Since cattiite is relatively unexplored in the literature, a first time evaluation reveals that it is cytocompatible, just like the other phases in the MgO-P2O5 (Mg-P) system. The cement composition prepared with 15% PVA in an aqueous medium achieved clinically relevant setting times, mechanical properties, and biodegradation. Simulated body fluid (SBF) soaking resulted in coating of bobierrite onto the cement particle surfaces. PMID- 27716637 TI - Adaptation of the microdosimetric kinetic model to hypoxia. AB - Ion beams present a potential advantage in terms of treatment of lesions with hypoxic regions. In order to use this potential, it is important to accurately model the cell survival of oxic as well as hypoxic cells. In this work, an adaptation of the microdosimetric kinetic (MK) model making it possible to account for cell hypoxia is presented. The adaptation relies on the modification of damage quantity (double strand breaks and more complex lesions) due to the radiation. Model parameters such as domain size and nucleus size are then adapted through a fitting procedure. We applied this approach to two cell lines, HSG and V79 for helium, carbon and neon ions. A similar behaviour of the parameters was found for the two cell lines, namely a reduction of the domain size and an increase in the sensitive nuclear volume of hypoxic cells compared to those of oxic cells. In terms of oxygen enhancement ratio (OER), the experimental data behaviour can be reproduced, including dependence on particle type at the same linear energy transfer (LET). Errors on the cell survival prediction are of the same order of magnitude than for the original MK model. Our adaptation makes it possible to account for hypoxia without modelling the OER as a function of the LET of the particles, but directly accounting for hypoxic cell survival data. PMID- 27716638 TI - Expanding the scale of molecular biophysics. AB - Here, I argue that some of the secrets of complex biological function rely on assemblies of many heterogeneous proteins that together enable sophisticated sensing and actuating processes. Evolution seems to delight in making these structures and in continually elaborating upon their capabilities. Developing tools that can go beyond the few protein limit, both on the experimental frontier and from a theoretical, conceptual framework, should be an extremely high priority for the next generation of molecular biophysicists. PMID- 27716639 TI - Depth-resolved 3D visualization of coronary microvasculature with optical microangiography. AB - In this study, we propose a novel implementation of optical coherence tomography based angiography combined with ex vivo perfusion of fixed hearts to visualize coronary microvascular structure and function. The extracorporeal perfusion of Intralipid solution allows depth-resolved angiographic imaging, control of perfusion pressure, and high-resolution optical microangiography. The imaging technique offers new opportunities for microcirculation research in the heart, which has been challenging due to motion artifacts and the lack of independent control of pressure and flow. With the ability to precisely quantify structural and functional features, this imaging platform has broad potential for the study of the pathophysiology of microvasculature in the heart as well as other organs. PMID- 27716640 TI - A promising new mechanism of ionizing radiation detection for positron emission tomography: modulation of optical properties. AB - Using conventional scintillation detection, the fundamental limit in positron emission tomography (PET) time resolution is strongly dependent on the inherent temporal variances generated during the scintillation process, yielding an intrinsic physical limit for the coincidence time resolution of around 100 ps. On the other hand, modulation mechanisms of the optical properties of a material exploited in the optical telecommunications industry can be orders of magnitude faster. In this paper we borrow from the concept of optics pump-probe measurement to for the first time study whether ionizing radiation can produce modulations of optical properties, which can be utilized as a novel method for radiation detection. We show that a refractive index modulation of approximately [Formula: see text] is induced by interactions in a cadmium telluride (CdTe) crystal from a 511 keV photon source. Furthermore, using additional radionuclide sources, we show that the amplitude of the optical modulation signal varies linearly with both the detected event rate and average photon energy of the radiation source. PMID- 27716641 TI - A versatile method for combining different biopolymers in a core/shell fashion by 3D plotting to achieve mechanically robust constructs. AB - Three-dimensional extrusion of two different biomaterials in a core/shell (c/s) fashion has gained much interest in the last couple of years as it allows for fabricating constructs with novel and interesting properties. We now demonstrate that combining high concentrated (16.7 wt%) alginate hydrogels as shell material with low concentrated, soft biopolymer hydrogels as core leads to mechanically stable and robust 3D scaffolds. Alginate, chitosan, gellan gum, gelatin and collagen hydrogels were utilized successfully as core materials-hydrogels which are too soft for 3D plotting of open-porous structures without an additional mechanical support. The respective c/s scaffolds were characterized concerning their morphology, mechanical properties and swelling behavior. It could be shown that core as well as shell part can be loaded with growth factors and that the release depends on core composition and shell thickness. Neither the plotting process nor the crosslinking with 1M CaCl2 denatured the proteins. When core and shell were loaded with different growth factors (VEGF and BMP-2, respectively) a dual release was achieved. Finally, live human endothelial cells were integrated in the core material, demonstrating that this new strategy can be used for bioprinting purposes as well. PMID- 27716642 TI - Automatic exposure control calibration and optimisation for abdomen, pelvis and lumbar spine imaging with an Agfa computed radiography system. AB - The use of three physical image quality metrics, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and mean effective noise equivalent quanta (eNEQm) have recently been examined by our group for their appropriateness in the calibration of an automatic exposure control (AEC) device for chest radiography with an Agfa computed radiography (CR) imaging system. This study uses the same methodology but investigates AEC calibration for abdomen, pelvis and spine CR imaging. AEC calibration curves were derived using a simple uniform phantom (equivalent to 20 cm water) to ensure each metric was held constant across the tube voltage range. Each curve was assessed for its clinical appropriateness by generating computer simulated abdomen, pelvis and spine images (created from real patient CT datasets) with appropriate detector air kermas for each tube voltage, and grading these against reference images which were reconstructed at detector air kermas correct for the constant detector dose indicator (DDI) curve currently programmed into the AEC device. All simulated images contained clinically realistic projected anatomy and were scored by experienced image evaluators. Constant DDI and CNR curves did not provide optimized performance but constant eNEQm and SNR did, with the latter being the preferred calibration metric given that it is easier to measure in practice. This result was consistent with the previous investigation for chest imaging with AEC devices. Medical physicists may therefore use a simple and easily accessible uniform water equivalent phantom to measure the SNR image quality metric described here when calibrating AEC devices for abdomen, pelvis and spine imaging with Agfa CR systems, in the confidence that clinical image quality will be sufficient for the required clinical task. However, to ensure appropriate levels of detector air kerma the advice of expert image evaluators must be sought. PMID- 27716643 TI - Evaluation of the microscopic dose enhancement for nanoparticle-enhanced Auger therapy. AB - The aim of this study is to investigate the dosimetric characteristics of nanoparticle-enhanced Auger therapy. Monte Carlo (MC) simulations were performed to assess electron energy spectra and dose enhancement distributions around a nanoparticle. In the simulations, two types of nanoparticle structures were considered: nanoshell and nanosphere, both of which were assumed to be made of one of five elements (Fe, Ag, Gd, Au, and Pt) in various sizes (2-100 nm). Auger electron emitting radionuclides (I-125, In-111, and Tc-99m) were simulated within a nanoshell or on the surface of a nanosphere. For the most promising combination of Au and I-125, the maximum dose enhancement was up to 1.3 and 3.6 for the nanoshell and the nanosphere, respectively. The dose enhancement regions were restricted within 20-100 nm and 0-30 nm distances from the surface of Au nanoshell and nanosphere, respectively. The dose enhancement distributions varied with sizes of nanoparticles, nano-elements, and radionuclides and thus should be carefully taken into account for biological modeling. If the nanoparticles are accumulated in close proximity to the biological target, this new type of treatment can deliver an enhanced microscopic dose to the target (e.g. DNA). Therefore, we conclude that Auger therapy combined with nanoparticles could have the potential to provide a better therapeutic effect than conventional Auger therapy alone. PMID- 27716644 TI - Influence of pH and ionic strength on electrostatic properties of ferredoxin, FNR, and hydrogenase and the rate constants of their interaction. AB - Ferredoxin (Fd) protein transfers electrons from photosystem I (PSI) to ferredoxin:NADP+-reductase (FNR) in the photosynthetic electron transport chain, as well as other metabolic pathways. In some photosynthetic organisms including cyanobacteria and green unicellular algae under anaerobic conditions Fd transfers electrons not only to FNR but also to hydrogenase-an enzyme which catalyzes reduction of atomic hydrogen to H2. One of the questions posed by this competitive relationship between proteins is which characteristics of thylakoid stroma media allow switching of the electron flow between the linear path PSI-Fd FNR-NADP+ and the path PSI-Fd-hydrogenase-H2. The study was conducted using direct multiparticle simulation approach. In this method protein molecules are considered as individual objects that experience Brownian motion and electrostatic interaction with the surrounding media and each other. Using the model we studied the effects of pH and ionic strength (I) upon complex formation between ferredoxin and FNR and ferredoxin and hydrogenase. We showed that the rate constant of Fd-FNR complex formation is constant in a wide range of physiologically significant pH values. Therefore it can be argued that regulation of FNR activity doesn't involve pH changes in stroma. On the other hand, in the model rate constant of Fd-hydrogenase interaction dramatically depends upon pH: in the range 7-9 it increases threefold. It may seem that because hydrogenase reduces protons it should be more active when pH is acidic. Apparently, regulation of hydrogenase's affinity to both her reaction partners (H+ and Fd) is carried out by changes in its electrostatic properties. In the dark, the protein is inactive and in the light it is activated and starts to interact with both Fd and H+. Therefore, we can conclude that in chloroplasts the rate of hydrogen production is regulated by pH through the changes in the affinity between hydrogenase and ferredoxin. PMID- 27716645 TI - How to include the variability of TMS responses in simulations: a speech mapping case study. AB - When delivered over a specific cortical site, TMS can temporarily disrupt the ongoing process in that area. This allows mapping of speech-related areas for preoperative evaluation purposes. We numerically explore the observed variability of TMS responses during a speech mapping experiment performed with a neuronavigation system. We selected four cases with very small perturbations in coil position and orientation. In one case (E) a naming error occurred, while in the other cases (NEA, B, C) the subject appointed the images as smoothly as without TMS. A realistic anisotropic head model was constructed of the subject from T1-weighted and diffusion-weighted MRI. The induced electric field distributions were computed, associated to the coil parameters retrieved from the neuronavigation system. Finally, the membrane potentials along relevant white matter fibre tracts, extracted from DTI-based tractography, were computed using a compartmental cable equation. While only minor differences could be noticed between the induced electric field distributions of the four cases, computing the corresponding membrane potentials revealed different subsets of tracts were activated. A single tract was activated for all coil positions. Another tract was only triggered for case E. NEA induced action potentials in 13 tracts, while NEB stimulated 11 tracts and NEC one. The calculated results are certainly sensitive to the coil specifications, demonstrating the observed variability in this study. However, even though a tract connecting Broca's with Wernicke's area is only triggered for the error case, further research is needed on other study cases and on refining the neural model with synapses and network connections. Case- and subject-specific modelling that includes both electromagnetic fields and neuronal activity enables demonstration of the variability in TMS experiments and can capture the interaction with complex neural networks. PMID- 27716646 TI - Modelling topical photodynamic therapy treatment including the continuous production of Protoporphyrin IX. AB - Most existing theoretical models of photodynamic therapy (PDT) assume a uniform initial distribution of the photosensitive molecule, Protoporphyrin IX (PpIX). This is an adequate assumption when the prodrug is systematically administered; however for topical PDT this is no longer a valid assumption. Topical application and subsequent diffusion of the prodrug results in an inhomogeneous distribution of PpIX, especially after short incubation times, prior to light illumination. In this work a theoretical simulation of PDT where the PpIX distribution depends on the incubation time and the treatment modality is described. Three steps of the PpIX production are considered. The first is the distribution of the topically applied prodrug, the second in the conversion from the prodrug to PpIX and the third is the light distribution which affects the PpIX distribution through photobleaching. The light distribution is modelled using a Monte Carlo radiation transfer model and indicates treatment depths of around 2 mm during daylight PDT and approximately 3 mm during conventional PDT. The results suggest that treatment depths are not only limited by the light penetration but also by the PpIX distribution.

AB - Porous hydroxyapatite (HA) scaffolds combined with a drug delivery system have attracted much attention for bone tissue engineering. In this study, an easy and highly efficient method was developed to immobilize salvianolic acid B (Sal B) loaded chitosan (CS) microspheres three dimensionally and homogeneously on the surface of HA scaffolds pre-coated with alginate. Porous HA scaffolds were prepared via a template-leaching process and CS microspheres (used as drug carriers) were fabricated by an emulsion method. To improve adhesion between the microspheres and HA scaffolds, alginate was used to pre-coat the porous surface of the HA scaffolds. Various concentrations of alginate were used to optimize the adhesion of Sal B-loaded CS microspheres to the scaffold surface. During the adherence process, coated HA scaffolds were immersed in an aqueous solution containing Sal B-loaded CS microspheres, followed by standing or shaking at 37 degrees C for a certain time. The results showed that the microspheres were solidly and homogeneously distributed on the porous surface of the alginate pre coated HA scaffolds via electrostatic interactions. Few microspheres detached from the porous surface, even after the HA scaffolds with microspheres were treated by shaking in distilled water for as long as 7 d. Compared with the static condition, the distribution of Sal B-loaded CS microspheres on the porous surface of pre-coated HA scaffolds in the shaken condition was more homogeneous and almost unaggregated. Additionally, the compressive strength of the scaffolds coated with alginate was obviously improved. The optimal alginate coating concentration was 1% (i.e. the microstructure of the porous surfaces of the HA scaffolds was almost unchanged). The release profile of Sal B over a 30 d immersion found an initial burst release followed by a sustained release. The result of cell culture in vitro was that 1% alginate-coated scaffolds with Sal B loaded CS microspheres obviously promoted cell proliferation after cell culture for 3 and 7 d, and cells were attached and uniformly distributed on the porous surface of the scaffolds. The strategy of incorporating drug-loaded microspheres with porous HA scaffolds could provide an excellent bone substitute for repair of bone tissue defects. PMID- 27716648 TI - Enhancing vascularization of a gelatin-based micro-cavitary hydrogel by increasing the density of the micro-cavities. AB - The transport of nutrients and oxygen by vascular networks into engineered tissue constructs is critical to their successful integration into host tissues. Hydrogel has achieved some promising results as scaffolds for vascularization. However, the vascularization of hydrogel is still constrained by its inherent submicron- or nano-sized pores. In this study, two gelatin-based micro-cavitary gel (Gel-MCG) constructs with varying densities of micro-cavities were developed with a photocrosslinkable gelatin methacrylate (Gel-MA) precursor and porogenic gelatin microspheres (MS), and their functions in supporting vascularization within hydrogels were evaluated with endothelial progenitor outgrowth cells (EPOCs). The increase of cavitary density could enhance the vascularization of Gel-MCG constructs. After 14 d of culture in vitro, the vascularization of Gel MCG constructs with higher cavitary density was significantly superior to that of gelatin spongy control and the fusion of vascularized cavities in the constructs could be observed. Further subcutaneous implantation of the Gel-MCG constructs with higher cavitary density into nude mice also showed obvious vascular invasion from host tissues. Taken together, these results indicate that the increase in cavitary density can efficiently facilitate the vascularization of Gel-MCG constructs both in vitro and in vivo and that such highly-porous Gel-MCG constructs have great potential to be a promising scaffold for the development of vascularized tissue constructs.

AB - The aim of this study was to investigate the venoarteriolar reflex (VAR) responses in type 1 (T1DM) and type 2 (T2DM) diabetes mellitus (DM) with polyneuropathy and to estimate their relationship with age, DM duration, initial cutaneous temperature and body mass index. Four groups of subjects were investigated: 1st group -20 patients with T1DM; 2nd group -50 patients with T2DM; 3rd group of 20 healthy subjects with similar age and body mass index (BMI) to the T1DM group; 4th group (Control2) of 24 healthy subjects adjusted by age and BMI to the T2DM group. The cutaneous perfusions of the big toe pulp were monitored as baseline perfusions at a temperature of 32 degrees C in supine and sitting position with hanging legs and back in supine position. Loss of venoarteriolar reflex responses was established in 75% of T1DM patients, 78% of T2DM patients and in none of the investigated healthy controls. Reduced venoarteriolar perfusion responses were established in both T1DM and T2DM patients with polyneuropathy compared with healthy subjects. Reliable positive associations between VAR responses and the age, DM duration and initial cutaneous temperature were found. PMID- 27716650 TI - Microvascular reactivity to thermal stimulation in patients with diabetes mellitus and polyneuropathy. AB - The study aimed to investigate local thermally induced microvascular reactivity in patients with type 1 (T1DM) or type 2 diabetes mellitus (T2DM) and polyneuropathy and to compare it with healthy controls. A hundred and fourteen subjects were investigated divided into 3 groups: 1st group -20 patients with T1DM; 2nd group -50 patients with T2DM; 3rd group -44 healthy controls. The skin perfusions of the first tiptoe were monitored by laser Doppler flowmetry during thermal test. The initial (PUi) and basal perfusions at 32 degrees C (PUb) tended to be higher in the DM groups and the PUb of T1DM group was higher compared with the healthy subjects. The perfusion responses to heating were attenuated in the patients compared with the controls. The calculated vasodilator heat-induced indices were significantly lower and the vasoconstrictor indices during relative cooling in the recovery period were significantly higher in DM patients related to the healthy subjects. The reduced cutaneous microvascular responses to local thermal stimulation in the plantar sides of the toes of both T1DM and T2DM patients with polyneuropathy were similar to those found by previous studies in other investigated sites of glabrous and nonglabrous skin of patients with DM. PMID- 27716651 TI - RBC aggregation in dextran solutions can be measured by flow cytometry. AB - The impact of macromolecules on RBC aggregation continues to be of interest, nevertheless present measurements still have limitations and need improvement. We applied flow cytometry to measure RBC aggregation in dextran T500 (Dx500) solution. The samples were fixed in the aggregated state by glutaraldehyde. Fixed RBC exhibit auto fluorescence, which can be detected by flow cytometry. Single cells, doublets, triplets and larger aggregates can be distinguished quantitatively and quickly due to the correlation between auto fluorescence intensity and number of RBC per measured event. With the increase in concentration of Dx500, percentages of all aggregates and bigger aggregates increased significantly at concentration of 2%, 4% and 6%, while decreased when the concentration reached 8% and 10%. The percentage of bigger aggregates in concentration of 4% was higher than that in 2% and 6%. The data of flow cytometry was confirmed by microscopic observation and are in good agreement with the literature. The method provide additional advantages to the conventional measurement of RBC aggregation. It gets the distribution of single cells and aggregates as derived from the microscopic observation with hematocrit of physiological level. It uses sample volume as 1/5~1/10 as needed in sendimentation and photometricmethods. PMID- 27716652 TI - Red blood cell distribution width is a survival predictor beyond anemia and Nt ProBNP in stable optimally medicated heart failure with reduced ejection fraction outpatients. AB - BACKGROUND: RDW is an automatic value obtained with the blood count, and represents the erythrocytes dimension variation. OBJECTIVE: To evaluate in optimally medicated outpatients with heart failure with reduced ejection fraction (HFrEF) the RDW prognostic value regarding survival in a multivariable model including anemia and Nt-ProBNP. METHODS: 233 consecutive outpatients, LVEF <40%, clinically stable were followed-up for 3-years in an HF Unit. End-point was all cause death. The RDW categorized according to the tertiles (T1 = <13.9; T2 14 15.2; T3> = 15.3). Anemia classified according to the WHO criteria. Cox survival model adjusted for clinical profile, optimal therapeutic, renal function, Nt ProBNP, etiology, atrial fibrillation, and anemia. RESULTS: (1) The 3-years death rate was 33.5%, and increased with the RDW tertiles (17.3%; 25%; 61.1%; p < 0.001). (2) The ROC curve for death associated with RDW (AUC 0.73; p < 0.001); (3) The adjusted death risk increased with the tertiles (Hazard-ratio '[HR] = 1.61; IC 95% 1.09-2.39; p = 0.017). RDW> = 15.3 had greater adjusted death risk than T1 (HR = 2.18; 95% CI 0.99-4.8; p = 0.05) and T1+T2 (HR = 1.54; 95% CI 1.13 2.09; p = 0.006). CONCLUSION: RDW determined in optimally medicated outpatients with HFrEF, during dry-state, is a strong, cheap, and independent predictor of long-term survival. PMID- 27716653 TI - Erythrocyte nitric oxide availability and oxidative stress following exercise. AB - Growing evidence has shown that acute exercise impairs erythrocyte membrane structure and function as a consequence of increased physical and chemical stress. Erythrocyte-synthesized nitric oxide (NO) is known to modulate membrane fluidity, and its bioavailability depends on the balance between its production and scavenging by reactive oxygen species. Here, we investigated whether a maximal exercise test could affect erythrocyte NO bioavailability and oxidative stress. Twelve men (26+/-4 years old, VO2peak 44.1+/-4.3 mL.kg-1.min-1) performed a treadmill maximal cardiopulmonary exercise test. Blood was collected at rest and immediately after exercise for erythrocytes isolation. Maximal exercise caused an increase in erythrocytes count, haemoglobin and haematocrit levels. There was no change in L-arginine influx into erythrocytes after exercise. Yet, nitric oxide synthase activity, and thus, NO production, was increased after maximal test, as well cyclic GMP levels. In relation to biomarkers of oxidative stress, maximal test resulted in increased levels of lipid peroxidation, and diminished superoxide dismutase activity. Neither glutathione peroxidase nor catalase activity was affected by maximal test. Our findings demonstrate that the increased erythrocyte membrane rigidity caused by an acute bout of exercise may be caused, in part, by an increased lipid oxidative damage caused by ROS produced exogenously. PMID- 27716654 TI - Body fat and blood rheology: Evaluation of the association between different adiposity indices and blood viscosity. AB - BACKGROUND: In recent years, new measures of body adiposity have been introduced: lipid accumulation product (LAP), body adiposity index (BAI) and body shape index (ABSI). These indices have been demonstrated to better associate with cardiovascular disease than other measures of adiposity. OBJECTIVES: The aim of the present study was to evaluate if LAP or BAI better associate with blood viscosity than other measures of adiposity (body mass index, BMI; waist circumference, WC; waist-to-hip ratio, W/HR; waist-to-height ratio, W/HtR). METHODS: 344 subjects were recruited for the present investigation. Exclusion criteria were: diabetes, elevated triglycerides, smoking and drug use. Blood lipids and glucose were measured by routine methods. Blood and plasma viscosity were measured by a cone-plate viscometer. Adiposity measures were computed as previously described. RESULTS: In simple correlation analyses, blood viscosity (BV) correlated with BMI, BAI, and LAP in males and with LAP in females. Correlations between plasma viscosity and adiposity indices were weak and not statistically significant. Other variables significantly related with BV were: gender, HDL- and LDL-Cholesterol, and triglycerides (p < 0.05). In multiple regression analysis only LAP was associated with BV. CONCLUSIONS: Our data suggest that LAP index is strongly associated to blood viscosity. This result, along with previous evidence, identifies LAP index as a potential cardiovascular risk marker. PMID- 27716655 TI - Circulating serum CK level vs. muscle impairment for in situ monitoring burden of disease in Mdx-mice. AB - BACKGROUND: Duchenne muscular dystrophy (DMD) consists of a lack in the expression of the subsarcolemmal protein dystrophin causing progressive muscle dysfunction. Among the widely applied animal models in DMD research is the C57BL/1010ScSn-Dmdmdx mouse, commonly referred to as the "mdx mouse". The potential benefit of novel interventions in this model is often assessed by variables such as functional improvement, histological changes, and creatine kinase (CK) serum levels as an indicator for the extent of in situ muscle damage. OBJECTIVE: Our objective was to determine to what extent the serum CK-level serves a surrogate for muscle dysfunction. METHODS: In this trial mdx mice were subjected to a four-limb wire-hanging test (WHT) to assess the physical performance as a reference for muscle function. As CK is a component of the muscle fiber cytosol, its serum activity is supposed to positively correlate with progressing muscle damage. Hence serum CK levels were measured to detect the degree of muscle impairment. The functional tests and the serum CK levels were analyzed for their specific correlation. RESULTS: Although physical performance decreased during the course of the experiment, latency to fall times in the WHT did not correlate with the CK level in mdx mice. CONCLUSION: Our data suggests that the serum CK activity might be a critical parameter to monitor the progression of muscle impairment in mdx mice. Further this study emphasizes the complexity of the DMD phenotype in the mdx mouse, and the care with which isolated parameters in this model should be interpreted. PMID- 27716656 TI - Diagnosis of perinephric retroperitoneal lymphangioma supported by contrast enhanced ultrasound (CEUS). AB - Lymphangiomas are a rare condition, which are characterized by multiple cystic lesions of a single or multiple organs that are thought to originate from intrauterine atypically distended and connected lymphatic tissue. We describe a case of a 56 years old woman with the final diagnosis of a perinephric lymphangioma. With the use of contrast-enhanced ultrasound (CEUS) it was possible to add valuable diagnostic information regarding the extent of the lymphangioma to surrounding tissue without the necessity to use additional ionizing radiation or nephrotoxic contrast agents. PMID- 27716659 TI - Clinical Response to Donepezil in Mild and Moderate Dementia: Relationship to Drug Plasma Concentration and CYP2D6 and APOE Genetic Polymorphisms. AB - The clinical response to donepezil in patients with mild and moderate dementia was investigated in relation to the drug plasma concentration and APOE and CYP2D6 polymorphisms. In a prospective naturalistic observational study, 42 patients with Alzheimer's disease (AD) and AD with cerebrovascular disease who took donepezil (10 mg) for 12 months were evaluated. Their DNA was genotyped, and the donepezil plasma concentrations were measured after 3, 6, and 12 months. Good responders scored >=-1 on the Mini-Mental State Examination at 12 months in comparison to the baseline score. The study results indicated the good response pattern was influenced by the concentration of donepezil, but not by APOE and CYP2D6 polymorphisms. PMID- 27716658 TI - The Diagnostic and Prognostic Value of Neuropsychological Assessment in Memory Clinic Patients. AB - BACKGROUND: Neuropsychological testing has long been embedded in daily clinical practice at memory clinics but the added value of a complete neuropsychological assessment (NPA) to standard clinical evaluation is unknown. OBJECTIVE: To evaluate the added diagnostic and prognostic value of NPA to clinical evaluation only in memory clinic patients. METHODS: In 221 memory clinic patients of a prospective cohort study, clinical experts diagnosed clinical syndrome (subjective cognitive impairment (SCI), mild cognitive impairment (MCI), or dementia) and etiology (Alzheimer's disease (AD) or no AD), and provided a prognosis of disease course (decline or no decline) before and after results of NPA were made available. The reference standard was a panel consensus based on all clinical information at baseline and up to 2 follow-up assessments. RESULTS: With NPA data available, clinicians changed their initial syndromal diagnosis in 22% of patients, and the etiological diagnosis as well as the prognosis in 15%. This led to an increase in correctly classified cases of 18% for syndromal diagnosis, 5% for etiological diagnosis, and 1% for prognosis. NPA data resulted in the largest improvement in patients initially classified as SCI (syndrome: 93.3% (n = 14) correctly reclassified, etiology: net reclassification improvement [NRI] = 0.61, prognosis: NRI = 0.13) or MCI (syndrome: 89.3% (n = 23) correctly reclassified, etiology: NRI = 0.17, prognosis: NRI = 0.14), while there was no improvement in patients with dementia (syndrome: 100% (n = 1) correctly reclassified, etiology: NRI = -0.05, prognosis: NRI = -0.06). Overall, inclusion of NPA in the diagnostic process increased confidence in all diagnoses with 6-7%. CONCLUSION: Administration of a complete NPA after standard clinical evaluation has added value for diagnosing cognitive syndrome and its underlying etiology in patients regarded as non-demented based on the first clinical impression. PMID- 27716660 TI - The Effect of Escitalopram on Mood and Cognition in Depressive Alzheimer's Disease Subjects. AB - BACKGROUND: Effective treatments to alleviate depression in Alzheimer's disease (AD) have been scarce. OBJECTIVE: To investigate the efficacy and tolerability of escitalopram in the treatment of depression in AD. METHODS: In this 12-week randomized, double-blind, placebo-controlled trial with open-label, 12-week extension, AD subjects over 50 years of age, with depression defined by Olin's provisional diagnostic criteria, were enrolled. The Cornell Scale for Depression in Dementia (CSDD), and other measures of depression and cognition were repeated. RESULTS: 91 subjects were screened, and 84 were randomized into either the study group or placebo group (n = 42 for both groups). Twenty-four subjects (29%) were unable to finish the study, yielding a per protocol population of 60 subjects (study group: n = 27; placebo group: n = 33). At week 12, differences in measures of depression and cognition between the two groups were not statistically significant. However, exploratory analysis suggested that further research on a subset of subjects with 'definite major depression' (baseline CSDD score >=18) is needed. The number of treatment-related adverse-events (AE) did not differ between groups (p = 0.83) and no serious treatment-related AE were observed. CONCLUSION: The use of escitalopram was well tolerated in depressive dementia patients. Future studies focusing on subjects with more severe levels of depression, and with more statistical power, will be needed. PMID- 27716661 TI - Genetic Prion Disease Caused by PRNP Q160X Mutation Presenting with an Orbitofrontal Syndrome, Cyclic Diarrhea, and Peripheral Neuropathy. AB - Patients with pathogenic truncating mutations in the prion gene (PRNP) usually present with prolonged disease courses with severe neurofibrillary tangle and cerebral amyloidosis pathology, but more atypical phenotypes also occur, including those with dysautonomia and peripheral neuropathy. We describe the neurological, cognitive, neuroimaging, and electrophysiological features of a 31 year-old man presenting with an orbitofrontal syndrome, gastrointestinal symptoms, and peripheral neuropathy associated with PRNP Q160X nonsense mutation, with symptom onset at age 27. The mutation was also detected in his asymptomatic father and a symptomatic paternal cousin; several members of prior generations died from early onset dementia. This is the first report of a family affected with the nonsense PRNP mutation Q160X displaying clear autosomal dominant disease in multiple family members and reduced penetrance. This case strengthens the evidence suggesting an association between PRNP truncating mutations and prion systemic amyloidosis. PRNP gene testing should be considered in any patient with atypical dementia, especially with early onset and neuropathy, even in the absence of a family history. PMID- 27716663 TI - Cerebrospinal Fluid Biomarkers for the Differential Diagnosis between Alzheimer's Disease and Frontotemporal Lobar Degeneration: Systematic Review, HSROC Analysis, and Confounding Factors. AB - BACKGROUND: Differential diagnosis in dementia is at present one of the main challenges both in clinical practice and research. Cerebrospinal fluid (CSF) biomarkers are included in the current diagnostic criteria of Alzheimer's disease (AD) but their clinical utility is still unclear. OBJECTIVE: We performed a systematic review of studies analyzing the diagnostic performance of CSF Abeta42, total tau (t-tau), and phosphorylated tau (p-tau) in the discrimination between AD and frontotemporal lobar degeneration (FTLD) dementias. METHODS: The following electronic databases were consulted until May 2016: Medline and PreMedline, EMBASE, PsycInfo, CINAHL, Cochrane Library, and CRD. For the first-time in the field, a Hierarchical Summary Receiver Operating Characteristic (HRSOC) model was applied, which avoids methodological problems of meta-analyses based on summary points of sensitivity and specificity values. We also investigated relevant confounders of CSF biomarkers' diagnostic performance such as age, disease duration, and global cognitive impairment. RESULTS: The p-tau/Abeta42 ratio showed the best diagnostic performance. No statistically significant effects of the confounders were observed. Nonetheless, the p-tau/Abeta42 ratio may be especially indicated for younger patients. P-tau may be preferable for less cognitively impaired patients (high MMSE scores) and the t-tau/Abeta42 ratio for more cognitively impaired patients (low MMSE scores). CONCLUSION: The p tau/Abeta42 ratio has potential for being implemented in the clinical routine for the differential diagnosis between AD and FTLD. It is of utmost importance that future studies report information on confounders such as age, disease duration, and cognitive impairment, which should also stimulate understanding of the role of these factors in disease mechanisms and pathophysiology. PMID- 27716664 TI - Normal Vitamin Levels and Nutritional Indices in Alzheimer's Disease Patients with Mild Cognitive Impairment or Dementia with Normal Body Mass Indexes. AB - Evidence supports an association between vitamin deficiencies and cognitive decline in Alzheimer's disease (AD). If vitamin deficiencies are causative for AD development, they should be detectable during very early stages of AD. Here we investigated nutritional factors among home-living patients diagnosed with mild cognitive impairment (MCI) or mild dementia due to AD, compared to healthy controls. Our study included 73 patients with AD (25 with MCI, 48 with dementia) and 63 cognitively intact age-matched controls. All participants underwent cognitive testing, somatic examination, and measurements of vitamins A, B1, B6, folate, B12, C, D, and E, and F2-alpha-isoprostane. Results are given as mean (SD). MMSE scores were 29.1 (1.0) for healthy controls, 27.4 (1.8) for patients with MCI, and 24.3 (3.2) for patients with dementia. Vitamin concentrations for the these groups, respectively, were as follows: B1 (nmol/l), 157 (29), 161 (35), and 161 (32); B6 (nmol/l), 57 (63), 71 (104), and 58 (44); folate (mmol/l), 23 (9), 26 (10), and 23 (11); B12 (pmol/l), 407 (159), 427 (116), and 397 (204); C (MUmol/l), 63 (18), 61 (16), and 63 (29); A (MUmol/l), 2.3 (0.6), 2.2 (0.5), and 2.3 (0.5); E (MUmol/l), 36 (6.3), 36 (6.9), and 36 (8.2); 25-OH vitamin D (nmol/l), 65 (18), 61 (19), and 65 (20); and 8-iso-PGFalpha (pg/ml), 64 (27); 60 (19), and 66 (51). These concentrations did not significantly differ (p<=0.05) between the three groups. Our results do not support the hypothesis that vitamin deficiencies play a causative role in the development of early cognitive impairment. PMID- 27716665 TI - Effects of DHA Supplementation on Hippocampal Volume and Cognitive Function in Older Adults with Mild Cognitive Impairment: A 12-Month Randomized, Double-Blind, Placebo-Controlled Trial. AB - Docosahexaenoic acid (DHA) is important for brain function, and higher DHA intake is inversely correlated with relative risk of Alzheimer's disease. The potential benefits of DHA supplementation in people with mild cognitive impairment (MCI) have not been fully examined. Our study aimed to determine the effect of DHA supplementation on cognitive function and hippocampal atrophy in elderly subjects with MCI. This was a randomized, double-blind, placebo-controlled trial in Tianjin, China. 240 individuals with MCI aged 65 years and over were recruited and equalized randomly allocated to the DHA or the placebo group. Participants received 12-month DHA supplementation (2 g/day) or corn oil as placebo. Both global and specific subdomains of cognitive function and hippocampal volume were measured at baseline, 6 months, and 12 months. Both changes were analyzed by repeated-measure analysis of variance (ANOVA). This trial has been registered: ChiCTR-IOR-15006058. A total of 219 participants (DHA: 110, Placebo: 109) completed the trial. The change in mean serum DHA levels was greater in the intervention group (+3.85%) compared to the control group (+1.06%). Repeated measures analyses of covariance showed that, over 12 months, there was a significant difference in the Full-Scale Intelligence Quotient (etap2 = 0.084; p = 0.039), Information (etap2 = 0.439; p = 0.000), and Digit Span (etap2 = 0.375; p = 0.000) between DHA-treated versus the placebo group. In addition, there were significant differences in volumes of left hippocampus (etap2 = 0.121, p = 0.016), right hippocampus (etap2 = 0.757, p = 0.008), total hippocampus (etap2 = 0.124, p = 0.023), and global cerebrum (etap2 = 0.145, p = 0.032) between the two groups. These findings suggest that DHA supplementation (2 g/day) for 12 months in MCI subjects can significantly improve cognitive function and slow the progression of hippocampal atrophy. Larger, longer-term confirmatory studies are warranted. PMID- 27716662 TI - Neutrophil Gelatinase-Associated Lipocalin and its Receptors in Alzheimer's Disease (AD) Brain Regions: Differential Findings in AD with and without Depression. AB - Co-existing depression worsens Alzheimer's disease (AD) pathology. Neutrophil gelatinase-associated lipocalin (NGAL) is a newly identified (neuro)inflammatory mediator in the pathophysiologies of both AD and depression. This study aimed to compare NGAL levels in healthy controls, AD without depression (AD-D), and AD with co-existing depression (AD+D) patients. Protein levels of NGAL and its receptors, 24p3R and megalin, were assessed in nine brain regions from healthy controls (n = 19), AD-D (n = 19), and AD+D (n = 21) patients. NGAL levels in AD-D patients were significantly increased in brain regions commonly associated with AD. In the hippocampus, NGAL levels were even further increased in AD+D subjects. Unexpectedly, NGAL levels in the prefrontal cortex of AD+D patients were comparable to those in controls. Megalin levels were increased in BA11 and amygdala of AD+D patients, while no changes in 24p3R were detected. These findings indicate significant differences in neuroimmunological regulation between AD patients with and without co-existing depression. Considering its known effects, elevated NGAL levels might actively promote neuropathological processes in AD with and without depression. PMID- 27716666 TI - Recent Increases in Hippocampal Tau Pathology in the Aging Japanese Population: The Hisayama Study. AB - BACKGROUND: The Hisayama study is a prospective cohort study of lifestyle-related diseases that commenced in 1961. Through it, a significant increasing trend in the prevalence of Alzheimer's disease has been observed over the past 18 years. OBJECTIVES: We sought to investigate the increases in brain pathology related to Alzheimer's disease using automated MATLAB morphometric analyses for quantifying tau pathology. METHODS: We examined a series of autopsied cases from Hisayama residents obtained between 1998 and 2003 (group A: 203 cases), and between 2009 and 2014 (group B: 232 cases). We developed custom software in MATLAB to analyze abnormal tau deposits quantitatively. Specimens were immunostained with both anti amyloid-beta-protein and anti-phosphorylated tau antibodies. RESULTS: Both the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) criteria for senile plaques and Braak stage for NFT were higher in group B. Morphometric analyses of the hippocampi also revealed a trend toward increased tau pathology in both men and women over 80 years of age in group B. The increases were also significant when the subjects were examined independently according to high or low CERAD scores and in all levels of AD neuropathologic change according to the National Institute on Aging-Alzheimer's Association guidelines (2012). CONCLUSION: We revealed a recent trend of increased tauopathy in the older people, which is partly independent of amyloid-beta pathology. PMID- 27716667 TI - Modeling the Distress of Spousal Caregivers of People with Dementia. AB - BACKGROUND: The progressive mobilization of spouse caregivers who take care of a person with dementia (PWD) can lead to situations of distress. OBJECTIVE: The current study sought to investigate the influence of the characteristics of the caregiving context on spousal caregiver distress. METHODS: 125 spousal caregivers participated in this study. The characteristics of the caregiving context were assessed using questionnaires. We examined a moderated-mediator model (Step 1) in which we hypothesized that PWD and caregiver characteristics and dyadic determinants contribute to spousal caregiver distress. This model was compared based on the age at onset of the disease and the gender of the caregiver (Step 2). RESULTS: The model revealed that poor self-rated health and a lack of family support accentuated spousal caregiver distress, whereas the feeling of being prepared and level of confidence decreased spousal caregiver distress. Moreover, the quality of couple adjustment affected spousal caregiver distress, and this effect was mediated by the severity of the PWD's symptoms. Regarding the age at onset of the disease, the path between Couple Adjustment and the Care recipient's impairments was more important for caregivers of person with early-onset dementia (PEOD). Female caregivers who reported poor self-rated health experienced greater distress. CONCLUSIONS: It would be interesting to create a support program that would incorporate these three areas of intervention regarding the progression of the disease: first, "preparedness modules"; second, "dyadic modules" (especially for caregivers of PEOD); and third, "family modules". Specific attention should be given to female caregivers who report poor self-rated health. PMID- 27716668 TI - Potentially Inappropriate Medication in Community-Dwelling Primary Care Patients who were Screened Positive for Dementia. AB - BACKGROUND: Potentially inappropriate medication (PIM) in older people is a risk factor for adverse drug effects. This risk is even higher in older people with dementia (PWD). OBJECTIVE: Our study aimed to determine (1) the prevalence of PIM among primary care patients who were screened positive for dementia and (2) the sociodemographic and clinical variables associated with the use of PIM. METHODS: DelpHi-MV (Dementia: life- and person-centered help in Mecklenburg-Western Pomerania) is a general practitioner-based, cluster-randomized, controlled intervention study to implement and evaluate an innovative concept of collaborative dementia care management in Germany. The comprehensive baseline assessment includes a home medication review. The present analyses are based on the data from 448 study participants (age 70+, DemTect <9). PIMs were identified using the list of Potentially Inappropriate Medications in the Elderly (Priscus). RESULTS: (1) A total of 99 study participants (22%) received at least one PIM. The highest prevalence was found for antidepressants, benzodiazepines, and analgetics. The most frequently prescribed PIMs were amitriptyline, etoricoxib, and doxazosin. (2) Use of a PIM was significantly associated with a diagnosis of a mental or behavioral disorder. CONCLUSIONS: The prescription rate of PIMs for community-dwelling PWD was comparable with the rates found for the general population of older people in Germany (20-29%). Antidepressants with anticholinergic properties and long-acting benzodiazepines were the most prescribed PIMs, despite having an unfavorable benefit-risk ratio. This high prevalence of PIM prescriptions in a vulnerable population of PWD indicates that standard care for dementia should include careful medication review and management. PMID- 27716669 TI - Daily Physical Activity Patterns During the Early Stage of Alzheimer's Disease. AB - BACKGROUND: Alzheimer's disease (AD) is a neurodegenerative disease that results in severe disability. Very few studies have explored changes in daily physical activity patterns during early stages of AD when components of physical function and mobility may be preserved. OBJECTIVE: Our study explored differences in daily physical activity profiles, independent of the effects of non-cognitive factors including physical function and age, among individuals with mild AD compared to controls. METHODS: Patients with mild AD and controls (n = 92) recruited from the University of Kansas Alzheimer's Disease Center Registry, wore the Actigraph GT3X+ for seven days, and provided objective physical function (VO2 max) and mobility data. Using multivariate linear regression, we explored whether individuals with mild AD had different daily average and diurnal physical activity patterns compared to controls independent of non-cognitive factors that may affect physical activity, including physical function and mobility. RESULTS: We found that mild AD was associated with less moderate-intensity physical activity (p < 0.05), lower peak activity (p < 0.01), and lower physical activity complexity (p < 0.05) particularly during the morning. Mild AD was not associated with greater sedentary activity or less lower-intensity physical activity across the day after adjusting for non-cognitive covariates. CONCLUSIONS: These findings suggest that factors independent of physical capacity and mobility may drive declines in moderate-intensity physical activity, and not lower-intensity or sedentary activity, during the early stage of AD. This underscores the importance of a better mechanistic understanding of how cognitive decline and AD pathology impact physical activity. Findings emphasize the potential value of designing and testing time-of-day specific physical activity interventions targeting individuals in the early stages of AD, prior to significant declines in mobility and physical function. PMID- 27716670 TI - BDNF Responses in Healthy Older Persons to 35 Minutes of Physical Exercise, Cognitive Training, and Mindfulness: Associations with Working Memory Function. AB - Brain-derived neurotrophic factor (BDNF) has a central role in brain plasticity by mediating changes in cortical thickness and synaptic density in response to physical activity and environmental enrichment. Previous studies suggest that physical exercise can augment BDNF levels, both in serum and the brain, but no other study has examined how different types of activities compare with physical exercise in their ability to affect BDNF levels. By using a balanced cross over experimental design, we exposed nineteen healthy older adults to 35-minute sessions of physical exercise, cognitive training, and mindfulness practice, and compared the resulting changes in mature BDNF levels between the three activities. We show that a single bout of physical exercise has significantly larger impact on serum BDNF levels than either cognitive training or mindfulness practice in the same persons. This is the first study on immediate BDNF effects of physical activity in older healthy humans and also the first study to demonstrate an association between serum BDNF responsivity to acute physical exercise and working memory function. We conclude that the BDNF increase we found after physical exercise more probably has a peripheral than a central origin, but that the association between post-intervention BDNF levels and cognitive function could have implications for BDNF responsivity in serum as a potential marker of cognitive health.

AB - BACKGROUND: Several studies have suggested that periodontal disease can exacerbate the pro-inflammatory status of the brain. Tooth loss is one of the alternative evaluation indices of periodontal disease. There are few data on the relationship between tooth loss and memory impairment, depending on the apolipoprotein E (APOE) E4 genotype. OBJECTIVE: To determine if tooth loss is associated with mild memory impairment (MMI) and if this association is modified by the presence of the APOEE4 allele. METHODS: A nested case-control study was conducted from 2007 to 2012 in Japan. Five hundred and thirty-seven Japanese subjects aged 65 years and over who were cognitively intact at baseline were analyzed. MMI at follow-up was evaluated. RESULTS: The median number of teeth at baseline was significantly lower in MMI participants (n = 179) than in controls (n = 358) (MMI: median 21.0, interquartile range 10.0-25.0 versus controls: 24.0, 14.0-27.0). After adjustment for demographics, vascular risk factors, and APOEE4 allele, the multivariate adjusted odds ratio (OR) of <=8 teeth was 1.97 (95% confidence interval [CI], 1.13-3.44) compared to 25-32 teeth. Participants with both the presence of at least 1 APOEE4 allele and <=8 teeth had a higher risk of MMI compared with those with neither (OR, 2.82; 95% CI, 1.15-6.91). Those with either risk factor alone did not have a higher risk of MMI. CONCLUSIONS: A lower number of teeth is related to risk of MMI. This may be primarily true for those individuals with an APOEE4 allele. PMID- 27716673 TI - The Utilization of Robotic Pets in Dementia Care. AB - BACKGROUND: Behavioral problems may affect individuals with dementia, increasing the cost and burden of care. Pet therapy has been known to be emotionally beneficial for many years. Robotic pets have been shown to have similar positive effects without the negative aspects of traditional pets. Robotic pet therapy offers an alternative to traditional pet therapy. OBJECTIVE: The study rigorously assesses the effectiveness of the PARO robotic pet, an FDA approved biofeedback device, in treating dementia-related symptoms. METHODS: A randomized block design with repeated measurements guided the study. Before and after measures included reliable, valid tools such as: RAID, CSDD, GDS, pulse rate, pulse oximetry, and GSR. Participants interacted with the PARO robotic pet, and the control group received standard activity programs. Five urban secure dementia units comprised the setting. RESULTS: 61 patients, with 77% females, average 83.4 years in age, were randomized into control and treatment groups. Compared to the control group, RAID, CSDD, GSR, and pulse oximetry were increased in the treatment group, while pulse rate, pain medication, and psychoactive medication use were decreased. The changes in GSR, pulse oximetry, and pulse rate over time were plotted for both groups. The difference between groups was consistent throughout the 12-week study for pulse oximetry and pulse rate, while GSR had several weeks when changes were similar between groups. CONCLUSIONS: Treatment with the PARO robot decreased stress and anxiety in the treatment group and resulted in reductions in the use of psychoactive medications and pain medications in elderly clients with dementia. PMID- 27716672 TI - Tocotrienol-Rich Fraction Modulates Amyloid Pathology and Improves Cognitive Function in AbetaPP/PS1 Mice. AB - Alzheimer's disease (AD) is the most common cause of dementia. The cardinal neuropathological characteristic of AD is the accumulation of amyloid-beta (Abeta) into extracellular plaques that ultimately disrupt neuronal function and lead to neurodegeneration. One possible therapeutic strategy therefore is to prevent Abeta aggregation. Previous studies have suggested that vitamin E analogs slow AD progression in humans. In the present study, we investigated the effects of the tocotrienol-rich fraction (TRF), a mixture of vitamin E analogs from palm oil, on amyloid pathology in vitro and in vivo. TRF treatment dose-dependently inhibited the formation of Abeta fibrils and Abeta oligomers in vitro. Moreover, daily TRF supplementation to AbetaPPswe/PS1dE9 double transgenic mice for 10 months attenuated Abeta immunoreactive depositions and thioflavin-S-positive fibrillar type plaques in the brain, and eventually improved cognitive function in the novel object recognition test compared with control AbetaPPswe/PS1dE9 mice. The present result indicates that TRF reduced amyloid pathology and improved cognitive functions, and suggests that TRF is a potential therapeutic agent for AD. PMID- 27716674 TI - Insula and Inferior Frontal Gyrus' Activities Protect Memory Performance Against Alzheimer's Disease Pathology in Old Age. AB - Apolipoprotein E (APOE) E4 carriers and patients with amnestic mild cognitive impairment (MCI) have high risk of developing Alzheimer's disease (AD). The Scaffolding Theory of Aging and Cognition proposes that recruitment of additional frontal brain regions can protect cognition against aging. This thesis has yet to be fully tested in older adults at high risk for AD. In the present study, 75 older participants (mean age: 74 years) were included. Applying a voxel-wise approach, fractional amplitude of low-frequency fluctuations (fALFF) in resting state functional neuroimaging data were analyzed as a function of APOEE4 status (carrier versus noncarrier) and clinical status (healthy control [HC] versus MCI) using a 2*2 analysis of covariance (ANCOVA). Measures of cognition and cerebrospinal fluid levels of amyloid- beta were also obtained. Three frontal regions were identified with significant interaction effects using ANCOVA (corrected p < 0.01): left-insula, left-inferior frontal gyrus (IFG), and right precentral gyrus. The HC/APOEE4 carrier group had significantly higher fALFF in all three regions than other groups. In the entire sample, for two regions (left insula and left IFG), a significant positive relationship between amyloid-beta and memory was only observed among individuals with low fALFF. Our results suggest higher activity in frontal regions may explain being cognitively normal among a subgroup of APOEE4 carriers and protect against the negative impact of AD associated pathology on memory. This is an observation with potential implications for AD therapeutics. PMID- 27716676 TI - Inflammation, Antiinflammatory Agents, and Alzheimer's Disease: The Last 22 Years. AB - Two basic discoveries spurred research into inflammation as a driving force in the pathogenesis of Alzheimer's disease (AD). The first was the identification of activated microglia in association with the lesions. The second was the discovery that rheumatoid arthritics, who regularly consume anti-inflammatory agents, were relatively spared from the disease. These findings led to an exploration of the inflammatory pathways that were involved in AD pathogenesis. A pivotal advance was the discovery that amyloid-beta protein (Abeta) activated the complement system. This focused attention on anti-inflammatories as blockers of complement activation. More than 15 epidemiological studies have since showed a sparing effect of non-steroidal anti-inflammatory drugs (NSAIDs) in AD. A consistent finding has been that the longer the NSAIDs were used prior to clinical diagnosis, the greater the sparing effect. The reason has since emerged from studies of biomarkers such as amyloid-beta (Abeta) levels in the cerebrospinal fluid and Abeta deposits in brain. They have established that the onset of AD commences at least a decade before cognitive decline permits clinical diagnosis. Such biomarker studies have revealed that a huge window of opportunity exists when application of NSAIDs, other anti-inflammatory agents, or complement activation blockers, could arrest further progress of AD, thus eliminating its manifestation. It can be anticipated that this principle will apply to many other chronic neurodegenerative diseases. Neuroinflammation, discovered in AD more than 30 years ago, has now become a major field of brain research today. Inhibiting it may be the key to successful treatment of many chronic neurological disorders. PMID- 27716675 TI - Tau Oligomers Associate with Inflammation in the Brain and Retina of Tauopathy Mice and in Neurodegenerative Diseases. AB - It is well-established that inflammation plays an important role in Alzheimer's disease (AD) and frontotemporal lobar dementia (FTLD). Inflammation and synapse loss occur in disease prior to the formation of larger aggregates, but the contribution of tau to inflammation has not yet been thoroughly investigated. Tau pathologically aggregates to form large fibrillar structures known as tangles. However, evidence suggests that smaller soluble aggregates, called oligomers, are the most toxic species and form prior to tangles. Furthermore, tau oligomers can spread to neighboring cells and between anatomically connected brain regions. In addition, recent evidence suggests that inspecting the retina may be a window to brain pathology. We hypothesized that there is a relationship between tau oligomers and inflammation, which are hallmarks of early disease. We conducted immunofluorescence and biochemical analyses on tauopathy mice, FTLD, and AD subjects. We showed that oligomers co-localize with astrocytes, microglia, and HMGB1, a pro-inflammatory cytokine. Additionally, we show that tau oligomers are present in the retina and are associated with inflammatory cells suggesting that the retina may be a valid non-invasive biomarker for brain pathology. These results suggest that there may be a toxic relationship between tau oligomers and inflammation. Therefore, the ability of tau oligomers to spread may initiate a feed-forward cycle in which tau oligomers induce inflammation, leading to neuronal damage, and thus more inflammation. Further mechanistic studies are warranted in order to understand this relationship, which may have critical implications for improving the treatment of tauopathies.

PMID- 27716680 TI - Comparison of Huntington's disease CAG Repeat Length Stability in Human Motor Cortex and Cingulate Gyrus. AB - Huntington's disease is caused by expansion of the CAG repeat in Huntingtin. This repeat has shown tissue-specific instability in mouse models and in a small number of post-mortem human samples. We used small-pool PCR to generate a modified instability index to quantify CAG instability within two brain regions from six human samples where cell loss has been associated with motor and mood symptoms: the motor cortex and cingulate gyrus. The expanded allele demonstrated instability in both regions, with minimal instability in the unexpanded allele. Region-specific differences were not observed, suggesting symptomatology may not be determined by repeat length instability. PMID- 27716681 TI - Separable scatter model of the detector and object contributions using continuously thickness-adapted kernels in CBCT. AB - Due to the increased cone beam coverage and the introduction of flat panel detector, the size of X-ray illumination fields has grown dramatically in Cone Beam Computed Tomography (CBCT), causing an increase in scatter radiation. Existing reconstruction algorithms do not model the scatter radiation, so scatter artifacts appear in the reconstruction images. The contribution of scattering of photons inside the detector itself becomes prominent and challenging in case of X ray source of high energy (over a few 100 keV) which is used in typical industrial Non Destructive Testing (NDT). In this paper, comprehensive evaluation of contribution of detector scatter is performed using continuously thickness adapted kernels. A separation of scatter due to object and the detector is presented using a four-Gaussian model. The results obtained prove that the scatter correction only due to the object is not sufficient to obtain reconstruction image free from artifacts as the detector also scatters considerably. The obtained results are also validated experimentally using a collimator to remove the contribution of object scatter. PMID- 27716682 TI - From the Editor's desk.

PMID- 27716687 TI - Different transseptal puncture for different procedures: Optimization of left atrial catheterization guided by transesophageal echocardiography. AB - BACKGROUND: Left atrial catheterization through transseptal puncture is frequently performed in cardiac catheterization procedures. Appropriate transseptal puncture is critical to achieve procedural success. AIMS: The aim of the study is to evaluate the feasibility of selective transseptal punctures, using a modified radiofrequency (RF) transseptal needle and transesophageal echocardiography (TEE), in different types of procedures that require specific sites of left atrial catheterization. SETTING AND DESIGN: This was an observational trial in a cardiac catheterization laboratory of a teaching hospital. MATERIALS AND METHODS: Patients undergoing different percutaneous procedures requiring atrial transseptal puncture such as atrial fibrillation (AF) ablation, left atrial appendage (LAA) occlusion, and mitral valve repair were included in the study. All procedures were guided by TEE and an RF transseptal needle targeting a specific region of the septum to perform the puncture. STATISTICAL ANALYSIS: The statistical analysis was descriptive only. RESULTS: RF assisted transseptal punctures were performed in six consecutive patients who underwent AF ablation (two patients), LAA closure (two patients), and mitral valve repair (two patients). In all patients, transseptal punctures were performed successfully at the desired site. No adverse events or complications were observed. CONCLUSIONS: Selective transseptal puncture, using TEE and an RF needle, is a feasible technique that can be used in multiple approaches requiring a precise site of access for left atrial catheterization. PMID- 27716688 TI - Accidental arterial puncture during right internal jugular vein cannulation in cardiac surgical patients. AB - BACKGROUND: The primary aim of this study was to compare the incidence of accidental arterial puncture during right internal jugular vein (RIJV) cannulation with and without ultrasound guidance (USG). The secondary end points were to assess if USG improves the chances of successful first pass cannulation and if BMI has an impact on incidence of arterial puncture and the number of attempts that are to be made for successful cannulation. SETTINGS AND DESIGN: Prospective observational study performed at a single tertiary cardiac care center. MATERIAL AND METHODS: 255 consecutive adult and pediatric cardiac surgical patients were included. In Group I (n = 124) USG was used for the right internal jugular vein cannulation and in Group II (n = 81) it was not used. There were 135 adult patients and 70 pediatric patients. STATISTICAL ANALYSIS: Demographic and categorical data were analyzed using Student 't' test and chi- square test was used for qualitative variables. RESULTS: The overall incidence of accidental arterial puncture in the entire study population was significantly higher when ultrasound guidance was not used (P< 0.001). In subgroup analysis, incidence of arterial puncture was significant in both adult (P = 0.03) and pediatric patients (P< 0.001) without USG. First attempt cannulation was more often possible in pediatric patients under USG (P = 0.03). In adult patients USG did not improve first attempt cannulation except in underweight patients. CONCLUSIONS: USG helped in the avoidance of inadvertent arterial puncture during RIJV cannulation and simultaneously improved the chances of first attempt cannulation in pediatric and in underweight adult cardiac surgical patients. PMID- 27716689 TI - Tricuspid annulus: A spatial and temporal analysis. AB - BACKGROUND: Traditional two-dimensional (2D) echocardiographic evaluation of tricuspid annulus (TA) dilation is based on single-frame measurements of the septolateral (S-L) dimension. This may not represent either the axis or the extent of dynamism through the entire cardiac cycle. In this study, we used real time 3D transesophageal echocardiography (TEE) to analyze geometric changes in multiple axes of the TA throughout the cardiac cycle in patients without right ventricular abnormalities. MATERIALS AND METHODS: R-wave-gated 3D TEE images of the TA were acquired in 39 patients undergoing cardiovascular surgery. The patients with abnormal right ventricular/tricuspid structure or function were excluded from the study. For each patient, eight points along the TA were traced in the 3D dataset and used to reconstruct the TA at four stages of the cardiac cycle (end- and mid-systole, end- and mid-diastole). Statistical analyses were applied to determine whether TA area, perimeter, axes, and planarity changed significantly over each stage of the cardiac cycle. RESULTS: TA area (P = 0.012) and perimeter (P = 0.024) both changed significantly over the cardiac cycle. Of all the axes, only the posterolateral-anteroseptal demonstrated significant dynamism (P < 0.001). There was also a significant displacement in the vertical axis between the points and the regression plane in end-systole (P < 0.001), mid diastole (P = 0.014), and mid-systole (P < 0.001). CONCLUSIONS: The TA demonstrates selective dynamism over the cardiac cycle, and its axis of maximal dynamism is different from the axis (S-L) that is routinely measured with 2D TEE. PMID- 27716690 TI - The myocardial protective effect of dexmedetomidine in high-risk patients undergoing aortic vascular surgery. AB - OBJECTIVE: The aim of the study was to assess the effect of dexmedetomidine in high-risk patients undergoing aortic vascular surgery. DESIGN: A randomized prospective study. SETTING: Cairo University, Egypt. MATERIALS AND METHODS: The study included 150 patients undergoing aortic vascular surgery. INTERVENTION: The patients were classified into two groups (n = 75). Group D: The patients received a loading dose of 1 MUg/kg dexmedetomidine over 15 min before induction and maintained as an infusion of 0.3 MUg/kg/h to the end of the procedure. Group C: The patients received an equal volume of normal saline. The medication was prepared by the nursing staff and given to anesthetist blindly. MEASUREMENTS: The monitors included the heart rate, mean arterial blood pressure, central venous pressure, electrocardiogram (ECG), serum troponin I level, end-tidal sevoflurane, and total dose of morphine in addition transthoracic echocardiography to the postoperative in cases with elevated serum troponin I level. MAIN RESULTS: The dexmedetomidine decreased heart rate and minimized the changes in blood pressure compared to control group (P < 0.05). Furthermore, it decreased the incidence of myocardial ischemia reflected by troponin I level, ECG changes, and the development of new regional wall motion abnormalities (P < 0.05). Dexmedetomidine decreased the requirement for nitroglycerin and norepinephrine compared to control group (P < 0.05). The incidence of hypotension and bradycardia was significantly higher with dexmedetomidine (P < 0.05). CONCLUSION: The dexmedetomidine is safe and effective in patients undergoing aortic vascular surgery. It decreases the changes in heart rate and blood pressure during the procedures. It provides cardiac protection in high-risk patients reflected by decreasing the incidence of myocardial ischemia and serum level of troponin. The main side effects of dexmedetomidine were hypotension and bradycardia. PMID- 27716691 TI - The efficacy of pre-emptive dexmedetomidine versus amiodarone in preventing postoperative junctional ectopic tachycardia in pediatric cardiac surgery. AB - OBJECTIVE: The objective of this study was to assess the effectiveness of pre emptive dexmedetomidine versus amiodarone in preventing junctional ectopic tachycardia (JET) in pediatric cardiac surgery. DESIGN: This is a prospective, controlled study. SETTING: This study was carried out at a single university hospital. SUBJECTS AND METHODS: Ninety patients of both sexes, American Society of Anesthesiologists Physical Status II and III, age range from 2 to 18 years, and scheduled for elective cardiac surgery for congenital and acquired heart diseases were selected as the study participants. INTERVENTIONS: Patients were randomized into three groups (30 each). Group I received dexmedetomidine 1 mcg/kg diluted in 100 ml of normal saline intravenously (IV) over a period of 20 min, and the infusion was completed 10 min before the induction followed by a 0.5 mcg/kg/h infusion for 72 h postoperative, Group II received amiodarone 5 mg/kg diluted in 100 ml of normal saline IV over a period of 20 min, and the infusion was completed 10 min before the induction followed by a 10-15 mcg/kg/h infusion for 72 h postoperative, and Group III received 100 ml of normal saline IV. Primary outcome was the incidence of postoperative JET. Secondary outcomes included vasoactive-inotropic score, ventilation time (VT), pediatric cardiac care unit stay, hospital length of stay, and perioperative mortality. MEASUREMENTS AND MAIN RESULTS: The incidence of JET was significantly reduced in Group I and Group II (P = 0.004) compared to Group III. Heart rate while coming off from cardiopulmonary bypass (CPB) was significantly low in Group I compared to Group II and Group III (P = 0.000). Mean VT, mean duration of Intensive Care Unit stay, and length of hospital stay (day) were significantly short (P = 0.000) in Group I and Group II compared to Group III (P = 0.000). CONCLUSION: Perioperative use of dexmedetomidine and amiodarone is associated with significantly decreased incidence of JET as compared to placebo without significant side effects. PMID- 27716692 TI - Comparison between marked versus unmarked introducer needle in real-time ultrasound-guided central vein cannulation: A prospective randomized study. AB - INTRODUCTION: Introducer needle tip is not clearly visible during the real-time ultrasound (US)-guided central vein cannulation (CVC). Blind tip leads to mechanical complications. This study was designed to evaluate whether real-time US-guided CVC with a marked introducer needle is superior to the existing unmarked needle. METHODOLOGY: Sixty-two critically ill patients aged 18-60 years of either sex were included in the study. The patients were randomized into two groups based on whether a marked or unmarked introducer needle was used. Both groups underwent real-time US-guided CVC by a single experienced operator. Aseptically, introducer needle was indented with markings spaced 0.5 cm (single marking) and every 1 cm (double marking). This needle was used in the marked group. Approximate depths (centimeter) of the anterior and posterior wall of the internal jugular vein, anterior wall of the internal carotid artery, and lung pleura were appreciated from the midpoint of the probe in short-axis view at the level of the cricoid cartilage. Access time (seconds) was recorded using a stopwatch. A number of attempts and complications such as arterial puncture, hematoma, and pneumothorax of either procedure were compared. RESULTS: Both marked needle and unmarked needle groups were comparable with regard to age, gender, severity scores, platelet counts, prothrombin time, and distance from the midpoint of the probe to the vein, artery, and pleura and skin-to-guide wire insertion access time. However, an average number of attempts (P = 0.03) and complications such as hematoma were significantly lower (P = 0.02) with the marked introducer needle group. Pneumothorax was not reported in any of the groups. CONCLUSION: Our study supports the idea that marked introducer needle can further reduce the iatrogenic complications of US-guided CVC. PMID- 27716694 TI - Perioperative utility of goal-directed therapy in high-risk cardiac patients undergoing coronary artery bypass grafting: "A clinical outcome and biomarker based study". AB - Goal-directed therapy (GDT) encompasses guidance of intravenous (IV) fluid and vasopressor/inotropic therapy by cardiac output or similar parameters to help in early recognition and management of high-risk cardiac surgical patients. With the aim of establishing the utility of perioperative GDT using robust clinical and biochemical outcomes, we conducted the present study. This multicenter randomized controlled study included 130 patients of either sex, with European system for cardiac operative risk evaluation >=3 undergoing coronary artery bypass grafting on cardiopulmonary bypass. The patients were randomly divided into the control and GDT group. All the participants received standardized care; arterial pressure monitored through radial artery, central venous pressure (CVP) through a triple lumen in the right internal jugular vein, electrocardiogram, oxygen saturation, temperature, urine output per hour, and frequent arterial blood gas (ABG) analysis. In addition, cardiac index (CI) monitoring using FloTracTM and continuous central venous oxygen saturation (ScVO2) using PreSepTM were used in patients in the GDT group. Our aim was to maintain the CI at 2.5-4.2 L/min/m2, stroke volume index 30-65 ml/beat/m2, systemic vascular resistance index 1500 2500 dynes/s/cm5/m2, oxygen delivery index 450-600 ml/min/m2, continuous ScVO2 >70%, and stroke volume variation <10%; in addition to the control group parameters such as CVP 6-8 mmHg, mean arterial pressure 90-105 mmHg, normal ABG values, oxygen saturation, hematocrit value >30%, and urine output >1 ml/kg/h. The aims were achieved by altering the administration of IV fluids and doses of inotropes or vasodilators. The data of sixty patients in each group were analyzed in view of ten exclusions. The average duration of ventilation (19.89 +/- 3.96 vs. 18.05 +/- 4.53 h, P = 0.025), hospital stay (7.94 +/- 1.64 vs. 7.17 +/- 1.93 days, P = 0.025), and Intensive Care Unit (ICU) stay (3.74 +/- 0.59 vs. 3.41 +/- 0.75 days, P = 0.012) was significantly less in the GDT group, compared to the control group. The extra volume added and the number of inotropic dose adjustments were significantly more in the GDT group. The two groups did not differ in duration of inotropic use, mortality, and other complications. The perioperative continuation of GDT affected the early decline in the lactate levels after 6 h in ICU, whereas the control group demonstrated a settling lactate only after 12 h. Similarly, the GDT group had significantly lower levels of brain natriuretic peptide, neutrophil gelatinase-associated lipocalin levels as compared to the control. The study clearly depicts the advantage of GDT for a favorable postoperative outcome in high-risk cardiac surgical patients. PMID- 27716693 TI - Effect of antiplatelet therapy on mortality and acute lung injury in critically ill patients: A systematic review and meta-analysis. AB - AIM: Platelet function is intricately linked to the pathophysiology of critical Illness, and some studies have shown that antiplatelet therapy (APT) may decrease mortality and incidence of acute respiratory distress syndrome (ARDS) in these patients. Our objective was to understand the efficacy of APT by conducting a meta-analysis. MATERIALS AND METHODS: We conducted a meta-analysis using PubMed, Central, Embase, The Cochrane Central Register, the ClinicalTrials.gov Website, and Google Scholar. Studies were included if they investigated critically ill patients receiving antiplatelet therapy and mentioned the outcomes being studied (mortality, duration of hospitalization, ARDS, and need for mechanical ventilation). RESULTS: We found that there was a significant reduction in all cause mortality in patients on APT compared to control (odds ratio [OR]: 0.83; 95% confidence interval [CI]: 0.70-0.97). Both the incidence of acute lung injury/ARDS (OR: 0.67; 95% CI: 0.57-0.78) and need for mechanical ventilation (OR: 0.74; 95% CI: 0.60-0.91) were lower in the antiplatelet group. No significant difference in duration of hospitalization was observed between the two groups (standardized mean difference: -0.02; 95% CI: -0.11-0.07). CONCLUSION: Our meta-analysis suggests that critically ill patients who are on APT have an improved survival, decreased incidence of ARDS, and decreased need for mechanical ventilation. PMID- 27716695 TI - Variations of transesophageal echocardiography practices in India: A survey by Indian College of Cardiac Anaesthesia. AB - CONTEXT: Use of perioperative transesophageal echocardiography (TEE) has expanded in India. Despite attempts to standardize the practice of TEE in cardiac surgical procedures, variation in practice and application exists. This is the first online survey by Indian College of Cardiac Anaesthesia, research and academic wing of the Indian Association of Cardiovascular Thoracic Anaesthesiologists (IACTA). AIMS: We hypothesized that variations in practice of intraoperative TEE exist among centers and this survey aimed at analyzing them. SETTINGS AND DESIGN: This is an online survey conducted among members of the IACTA. SUBJECTS AND METHODS: All members of IACTA were contacted using online questionnaire fielded using SurveyMonkeyTM software. There were 21 questions over four pages evaluating infrastructure, documentation of TEE, experience and accreditation of anesthesiologist performing TEE, and finally impact of TEE on clinical practice. Questions were also asked about national TEE workshop conducted by the IACTA, and suggestions were invited by members on overseas training. RESULTS: Response rate was 29.7% (382/1222). 53.9% were from high-volume centers (>500 cases annually). TEE machine/probe was available to 75.9% of the respondents and those in high volume centers had easier (86.9%) access. There was poor documentation of preoperative consent (23.3%) as well as TEE findings (66%). Only 18.2% of responders were board qualified. Almost 90% of the responders felt surgeons respected their TEE diagnosis. Around half of the responders felt that new intraoperative findings by TEE were considered in decision-making in most of the cases and 70% of the responders reported that surgical plan was altered based on TEE finding more than 10 times in the last year. Despite this, only 5% of the responders in this survey were monetarily awarded for performing impactful skill of TEE. Majority (57%) felt that there is no need for overseas training for Indian cardiac anesthesiologists. CONCLUSIONS: In this survey of members of the IACTA, use of TEE has increased substantially, but still a lot of variations in practice patterns exist in India. There is urgent need for improving TEE certification and upgrade documentation standards, motivate use of TTE across all centers, promote awareness and usefulness of TEE use among surgical fraternity, monitor impact of TEE, and support separate remuneration policy in India. PMID- 27716696 TI - Early enteral nutrition therapy in congenital cardiac repair postoperatively: A randomized, controlled pilot study. AB - BACKGROUND AND OBJECTIVES: Adequate nutritional supplementation in infants with cardiac malformations after surgical repair is a challenge. Critically ill infants in the early postoperative period are in a catabolic stress. The mismatch between estimated energy requirement (EER) and the intake in the postoperative period is multifactorial, predisposing them to complications such as immune deficiency, more infection, and growth failure. This study aimed to assess the feasibility and efficacy of enriched breast milk feed on postoperative recovery and growth of infants after open heart surgery. METHODOLOGY: Fifty infants <6 months of age were prospectively randomized in the trial for enteral nutrition (EN) postoperatively from day 1 to 10, after obtaining the Institute Ethics Committee's approval. They were equally divided into two groups on the basis of the feed they received: Control group was fed with expressed breast milk (EBM; 0.65 kcal/ml) and intervention group was fed with EBM + energy supplementation/fortification with human milk fortifier (7.5 kcal/2 g)/Simyl medium-chain triglyceride oil (7.8 kcal/ml). Energy need for each infant was calculated as per EER at 90 kcal/kg/day, as the target requirement. The intra- and post-operative variables such as cardiopulmonary bypass and aortic cross clamp times, ventilation duration, Intensive Care Unit (ICU), and hospital length of stay and mortality were recorded. Anthropometric and hematological parameters and infection control data were recorded in a predesigned pro forma. Data were analyzed using Stata 14.1 software. RESULTS: The duration of mechanical ventilation, length of ICU stay (LOIS), length of hospital stay (LOHS), infection rate, and mortality rate were lower in the intervention group compared to the control group although none of the differences were statistically significant. Infants in control group needed mechanical ventilation for about a day more (i.e., 153.6 +/- 149.0 h vs. 123.2 +/- 107.0 h; P = 0.20) than those in the intervention group. Similarly, infants in control group stayed for longer duration in the ICU (13.2 +/- 8.9 days) and hospital (16.5 +/- 9.8 days) as compared to the intervention group (11.0 +/- 6.1 days; 14.1 +/- 7.0 days) (P = 0.14 and 0.17, respectively). The LOIS and LOHS were decreased by 2.2 and 2.4 days, respectively, in the intervention group compared to control group. The infection rate (3/25; 5/25) and mortality rate (1/25; 2/25) were lower in the intervention group than those in the control group. The energy intake in the intervention group was 40 kcal more (i.e., 127.2 +/- 56.1 kcal vs. 87.1 +/- 38.3 kcal) than the control group on the 10th postoperative day. CONCLUSIONS: Early enteral/oral feeding after cardiac surgery is feasible and recommended. In addition, enriching the EBM is helpful in achieving the maximum possible calorie intake in the postoperative period. EN therapy might help in providing adequate nutrition, and it decreases ventilation duration, infection rate, LOIS, LOHS, and mortality. PMID- 27716697 TI - Effect of prophylaxis of magnesium sulfate for reduction of postcardiac surgery arrhythmia: Randomized clinical trial. AB - BACKGROUND: Arrhythmia is a common complication after heart surgery and is a major source of morbidity and mortality. AIMS: This study aimed to study the effect of magnesium sulfate (MgSO4) for reduction of postcardiac surgery arrhythmia. SETTING AND DESIGN: This study is performed in the cardiac operating room and Intensive Care Unit (ICU) of Shahid Madani Hospital of Tabriz (Iran) between January 1, 2014, and September 30, 2014. This study is a double-blind, randomized controlled trial. MATERIALS AND METHODS: In Group 1 (group magnesium [Mg]), eighty patients received 30 mg/kg MgSO4in 500 cc normal saline and in Group 2 (group control), eighty patients received 500 cc normal saline alone. STATISTICAL ANALYSIS: The occurrence of arrhythmia was compared between groups by Chi-square and Fisher's exact test. In addition, surgical time, length of ICU stay, and length of hospital stay were compared by independent t-test. P< 0.05 was considered as significant. RESULTS: There was a significant difference in the incidence of arrhythmia between two groups (P = 0.037). The length of ICU stay was 3.4 +/- 1.4 and 3.73 +/- 1.77 days in group MgSO4and control group, respectively, and there was no statistically significant difference between two groups (P = 0.2). CONCLUSION: Mg significantly decreases the incidence of all type of postcardiac surgery arrhythmia and hospital length of stay at patients undergo cardiac surgery. We offer prophylactic administration of Mg at patients undergo cardiac surgery. PMID- 27716698 TI - Hyperlactatemia in patients undergoing adult cardiac surgery under cardiopulmonary bypass: Causative factors and its effect on surgical outcome. AB - OBJECTIVES OF THE STUDY: To identify the factors causing high lactate levels in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) and to assess the association between high blood lactate levels and postoperative morbidity and mortality. METHODS: A retrospective observational study including 370 patients who underwent cardiac surgeries under cardiopulmonary bypass. The patients were divided into 2 groups based on serum lactate levels; those with serum lactate levels greater than or equal to 4 mmol/L considered as hyperlactatemia and those with serum lactate levels less than 4 mmol/L. Blood lactate samples were collected intraoperatively and postoperatively in the ICU. Preoperative and intraoperative risk factors for hyperlactatemia were identified using the highest intraoperative value of lactate. The postoperative morbidity and mortality associated with hyperlactatemia was studied using the overall (intraoperative and postoperative values) peak lactate levels. Preoperative clinical data, perioperative events and postoperative morbidity and mortality were recorded. RESULTS: Intraoperative peak blood lactate levels of 4.0 mmol/L or more were present in 158 patients (42.7%). Females had higher peak intra operative lactate levels (P = 0.011). There was significant correlation between CPB time (Pearson correlation coefficient r = 0.024; P = 0.003) and aortic cross clamp time (r = 0.02, P = 0.007) with peak intraoperative blood lactate levels. Patients with hyperlactatemia had significantly higher rate of postoperative morbidity like atrial fibrillation (19.9% vs. 5.3%; P = 0.004), prolonged requirement of inotropes (34% vs. 11.8%; P = 0.001), longer stay in the ICU (P = 0.013) and hospital (P = 0.001). CONCLUSIONS: Hyperlactatemia had significant association with post-operative morbidity. Detection of hyperlactatemia in the perioperative period should be considered as an indicator of inadequate tissue oxygen delivery and must be aggressively corrected. PMID- 27716699 TI - Perioperative management of patients with left ventricular assist devices undergoing noncardiac surgery. AB - AIM: The aim of this study was to describe our institutional experience, primarily with general anesthesiologists consulting with cardiac anesthesiologists, caring for left ventricular assist device (LVAD) patients undergoing noncardiac surgery. MATERIALS AND METHODS: This is a retrospective review of the population of patients with LVADs at a single institution undergoing noncardiac procedures between 2009 and 2014. Demographic, perioperative, and procedural data collected included the type of procedure performed, anesthetic technique, vasopressor requirements, invasive monitors used, anesthesia provider type, blood product management, need for postoperative intubation, postoperative disposition and length of stay, and perioperative complications including mortality. STATISTICAL ANALYSIS: Descriptive statistics for categorical variables are presented as frequency distributions and percentages. Continuous variables are expressed as mean +/- standard deviation and range when applicable. RESULTS: During the study, 31 patients with LVADs underwent a total of 74 procedures. Each patient underwent an average of 2.4 procedures. Of the total number of procedures, 48 (65%) were upper or lower endoscopies. Considering all procedures, 81% were performed under monitored anesthesia care (MAC). Perioperative care was provided by faculty outside of the division of cardiac anesthesia in 62% of procedures. Invasive blood pressure monitoring was used in 27 (36%) procedures, and a central line, peripherally inserted central catheter or midline was in place preoperatively and used intraoperatively for 38 (51%) procedures. Vasopressors were not required in the majority (65; 88%) of procedures. There was one inhospital mortality secondary to multiorgan failure; 97% of patients survived to discharge after their procedure. CONCLUSION: At our institution, LVAD patients undergoing noncardiac procedures most frequently require endoscopy. These procedures can frequently be done safely under MAC, with or without consultation by a cardiac anesthesiologist. PMID- 27716700 TI - The formation of bronchocutaneous fistulae due to retained epicardial pacing wires: A literature review. AB - Temporary epicardial pacing wires during open-heart surgery are routinely used both for diagnostic and treatment purposes. In complicated cases where patients are unstable or the wires are difficult to remove, the pacing wires are cut at the skin level and allowed to retract by themselves. This procedure rarely causes complications. However, there have been cases reporting that retained pacing wires are linked to the formation of sterno-bronchial fistulae, which may present a while after the date of operation and are usually infected. This review aims to study the cases presenting sterno-bronchial fistulae due to retained epicardial pacing wires and to highlight the important factors associated with these. It is important to note these complications, as fistulae may cause a variety of problems to the patient if undiagnosed and left untreated. With the aid of scans such as fistulography, fistulae can be identified and treated and will improve the patients' health dramatically. PMID- 27716702 TI - Global end-diastolic volume an emerging preload marker vis-a-vis other markers - Have we reached our goal? AB - A reliable estimation of cardiac preload is helpful in the management of severe circulatory dysfunction. The estimation of cardiac preload has evolved from nuclear angiography, pulmonary artery catheterization to echocardiography, and transpulmonary thermodilution (TPTD). Global end-diastolic volume (GEDV) is the combined end-diastolic volumes of all the four cardiac chambers. GEDV has been demonstrated to be a reliable preload marker in comparison with traditionally used pulmonary artery catheter-derived pressure preload parameters. Recently, a new TPTD system called EV1000TM has been developed and introduced into the expanding field of advanced hemodynamic monitoring. GEDV has emerged as a better preload marker than its previous conventional counterparts. The advantage of it being measured by minimum invasive methods such as PiCCOTM and newly developed EV1000TM system makes it a promising bedside advanced hemodynamic parameter. PMID- 27716701 TI - Cardiac surgery-associated acute kidney injury. AB - Cardiac surgery-associated acute kidney injury (CSA-AKI) is a well-recognized complication resulting with the higher morbid-mortality after cardiac surgery. In its most severe form, it increases the odds ratio of operative mortality 3-8 fold, length of stay in the Intensive Care Unit and hospital, and costs of care. Early diagnosis is critical for an optimal treatment of this complication. Just as the identification and correction of preoperative risk factors, the use of prophylactic measures during and after surgery to optimize renal function is essential to improve postoperative morbidity and mortality of these patients. Cardiopulmonary bypass produces an increased in tubular damage markers. Their measurement may be the most sensitive means of early detection of AKI because serum creatinine changes occur 48 h to 7 days after the original insult. Tissue inhibitor of metalloproteinase-2 and insulin-like growth factor-binding protein 7 are most promising as an early diagnostic tool. However, the ideal noninvasive, specific, sensitive, reproducible biomarker for the detection of AKI within 24 h is still not found. This article provides a review of the different perspectives of the CSA-AKI, including pathogenesis, risk factors, diagnosis, biomarkers, classification, postoperative management, and treatment. We searched the electronic databases, MEDLINE, PubMed, EMBASE using search terms relevant including pathogenesis, risk factors, diagnosis, biomarkers, classification, postoperative management, and treatment, in order to provide an exhaustive review of the different perspectives of the CSA-AKI. PMID- 27716705 TI - Windsock deformity of interatrial septum. AB - Classical "Windsock deformity" is associated with ruptured aneurysmal sinus of Valsalva. The echocardiographic definition for Atrial septal aneurysm (ASA) in children based on dimensions is lacking. Rupture of an ASA, though uncommon, may lead to cardiac failure due to acute RV volume overload. An untreated ASA may be complicated with thrombus formation. PMID- 27716704 TI - Role of hybrid operating room in surgery for the right atrial thrombus, pulmonary thrombi, and ventricular septal rupture after myocardial infarction. AB - Free-floating right heart thrombi are uncommon and need emergency treatment in view of their tendency to dislodge and cause pulmonary embolism. We report a successful surgical management of a patient who had large mobile right atrial thrombus, bilateral pulmonary thrombi, coronary artery disease, and postmyocardial infarction ventricular septal rupture (VSR). The patient underwent coronary angiography, inferior vena cava filter placement, removal of thrombi from the right atrium and pulmonary arteries, repair of VSR, and coronary artery bypass graft surgery in a hybrid operating room. PMID- 27716703 TI - Strategies for blood conservation in pediatric cardiac surgery. AB - Cardiac surgery accounts for the majority of blood transfusions in a hospital. Blood transfusion has been associated with complications and major adverse events after cardiac surgery. Compared to adults it is more difficult to avoid blood transfusion in children after cardiac surgery. This article takes into account the challenges and emphasizes on the various strategies that could be implemented, to conserve blood during pediatric cardiac surgery. PMID- 27716706 TI - Double valve replacement in a patient with implantable cardioverter defibrillator with severe left ventricular dysfunction. AB - Recent data from landmark trials suggest that the indications for cardiac pacing and implantable cardioverter defibrillators (ICDs) are set to expand to include heart failure, sleep-disordered breathing, and possibly routine implantation in patients with myocardial infarction and poor ventricular function.[1] This will inevitably result in more patients with cardiac devices undergoing surgeries. Perioperative electromagnetic interference and their potential effects on ICDs pose considerable challenges to the anesthesiologists.[2] We present a case of a patient with automatic ICD with severe left ventricular dysfunction posted for double valve replacement. PMID- 27716707 TI - Left ventricular mass: A tumor or a thrombus diagnostic dilemma. AB - Left ventricular (LV) mass is a rare condition, of which the most common is thrombus. Echocardiography is a very useful modality of investigation to evaluate the LV mass. We are reporting a case of LV mass presenting with neurological symptom. The diagnosis of this mass was dilemma as the echocardiographic features were favoring tumor as well as thrombi. Mass (a) measuring 3.8 cm * 1.9 cm attached to the left ventricle apex appeared to be pedunculated tumor and mass (b) measuring 2.4 cm * 1.8 cm attached to the chordae of anterior mitral leaflet resembled a thrombus or an embolized tumor entangled in the chordae. A differential diagnosis for the LV mass is thrombus, tumors such as fibroma, and vegetation. Preoperative detection of a thrombus leads to an alteration in surgical steps. A large and mobile thrombus with or without a hemodynamic alteration is an indication for surgical removal to prevent stroke, myocardial infarction, mesenteric ischemia, renal infarction, gangrene of the limbs, and mortality. PMID- 27716708 TI - Transesophageal echo diagnosis of perioperative unusual transient left ventricular apical ballooning syndrome. AB - Stress cardiomyopathy, or Takotsubo syndrome, is a widely recognized cardiac pathology with a clinical presentation similar to acute coronary syndrome and related to physical or emotional stress. Perioperatively, it is challenging to identify it given the variety of forms and scenarios in which it can present. We describe a 22-year-old patient with an atypical presentation of Takotsubo syndrome during anesthesia induction, which highlights the usefulness of transesophageal echocardiography for the initial diagnosis. PMID- 27716710 TI - Transesophageal echocardiography-guided thrombectomy of intracardiac renal cell carcinoma without cardiopulmonary bypass. AB - Advanced renal cell carcinoma (RCC) resection has important anesthetic management implications, particularly when tumor extends, suprahepatic, into the right atrium. Use of transesophageal echocardiogram (TEE) is essential in identifying tumor extension and guiding resection. Latest surgical approach avoids venovenous and cardiopulmonary bypass yet requires special precautions and interventions on the anesthesiologist's part. We present a case of Level IV RCC resected without cardiopulmonary bypass and salvaged by TEE guidance and detection of residual intracardiac tumor. PMID- 27716709 TI - Valve-in-valve-in homograft: A case of a repeat transcatheter aortic valve replacement in a patient with an aortic homograft. AB - In recent years, the use of transcatheter aortic valve replacement (TAVR) has extended beyond the treatment of native aortic valve stenosis in patients with high surgical risk. TAVR is increasingly being performed for bioprosthetic aortic valve failure, i.e., the valve-in-valve (VIV) procedure. Establishing the success of a VIV procedure can be challenging in these cases. Furthermore, the limited availability of prostheses sizes further complicates the management of these patients. We present an unusual case of a repeat TAVR in a patient who previously had a VIV procedure in an aortic homograft. PMID- 27716711 TI - Critical decision of operability in congenital heart disease patient with severe pulmonary hypertension. AB - Repair of congenital heart disease in the presence of high pulmonary pressure has always been a contentious issue. Pulmonary vascular resistance (PVR) is considered important for establishing operability in these patients. However, PVR estimation is not always accurate and cannot solely be relied upon to make critical decision of operability. Clinical examination, chest X-ray, and echocardiography are also important indicators of pulmonary vascular disease. Knowledge of pits and falls of each investigation is important for appropriate management in these patients. We present a case report of successfully operated, 6-year-old child with anomalous origin of the right pulmonary artery from aorta, deemed inoperable on the basis of PVR estimation. PMID- 27716712 TI - A lethal tension pneumothorax during minimally invasive coronary artery bypass surgery: Can transesophageal echocardiography pick it? AB - Minimally invasive cardiac surgery is establishing itself as the standard of care across the world. MICS CABG is currently performed in only a few centers. Hemodynamics disturbances are peculiar during MICS CABG due to space constraints. We report a 70-year-old man who underwent MICS CABG who developed tension pneumothorax during revascularization that was diagnosed in a novel way. PMID- 27716713 TI - Anesthetic management of patent ductus arteriosus in adults. AB - Patent ductus arteriosus (PDA) is an extracardiac left to right shunt. It should be corrected at an early age, but some patients may survive into adult life even without repair. Anesthetic management for adult patients with PDA poses many challenges for the anesthesiologist due to alterations in the cardiopulmonary physiology. We report successful anesthesia management of a case of an adult patient of PDA with moderate pulmonary artery hypertension with infective endarteritis (two large mobile vegetations at the pulmonary end of the duct).

PMID- 27716721 TI - Guidelines for the management of Stevens-Johnson syndrome/toxic epidermal necrolysis: An Indian perspective. AB - BACKGROUND: Stevens-Johnson syndrome and toxic epidermal necrolysis are severe, life-threatening mucocutaneous adverse drug reactions with a high morbidity and mortality that require immediate medical care. The various immunomodulatory treatments include systemic corticosteroids, cyclosporine, intravenous immunoglobulin, cyclophosphamide, plasmapheresis and tumor necrosis factor-alpha inhibitors. AIM: The ideal therapy of Stevens-Johnson syndrome/toxic epidermal necrolysis still remains a matter of debate as there are only a limited number of studies of good quality comparing the usefulness of different specific treatments. The aim of this article is to comprehensively review the published medical literature and frame management guidelines suitable in the Indian perspective. METHODS: The Indian Association of Dermatologists, Venereologists and Leprologists (IADVL) assigned the task of preparing these guidelines to its special interest group on cutaneous adverse drug reactions. The group performed a comprehensive English language literature search for management options in Stevens-Johnson syndrome/toxic epidermal necrolysis across multiple databases (PubMed, EMBASE, MEDLINE and Cochrane) for keywords (alone and in combination) and MeSH items such as "guidelines," "Stevens-Johnson syndrome," "toxic epidermal necrolysis," "corticosteroids," "intravenous immunoglobulin," "cyclosporine" and "management." The available evidence was evaluated using the strength of recommendation taxonomy and graded using a three-point scale. A draft of clinical recommendations was developed on the best available evidence which was also scrutinized and critically evaluated by the IADVL Academy of Dermatology. Based on the inputs received, this final consensus statement was prepared. RESULTS: A total of 104 articles (meta-analyses, prospective and retrospective studies, reviews [including chapters in books], previous guidelines [including Indian guidelines of 2006] and case series) were critically evaluated and the evidence thus gathered was used in the preparation of these guidelines. RECOMMENDATIONS: This expert group recommends prompt withdrawal of the culprit drug, meticulous supportive care, and judicious and early (preferably within 72 h) initiation of moderate to high doses of oral or parenteral corticosteroids (prednisolone 1-2 mg/kg/day or equivalent), tapered rapidly within 7-10 days. Cyclosporine (3-5 mg/kg/day) for 10-14 days may also be used either alone, or in combination with corticosteroids. Owing to the systemic nature of the disease, a multidisciplinary approach in the management of these patients is helpful. PMID- 27716722 TI - Biologics or biosimilars: What is the difference?

PMID- 27716727 TI - The Differential Impact of Emphysema on Respiratory Symptoms and 6-Minute Walk Distance in HIV Infection. AB - BACKGROUND: Emphysema is more prevalent in HIV-infected (HIV+) patients independent of smoking behavior. Nonetheless, health effects of emphysema in this population are poorly understood. We determined whether emphysema is associated with a greater burden of pulmonary symptoms and a lower 6-minute walk distance (6MWD) in HIV+ compared with HIV-uninfected (HIV-) subjects. METHODS: We performed a cross-sectional analysis of 170 HIV+ and 153 HIV- subjects in the Examinations of HIV-Associated Lung Emphysema (EXHALE) cohort study. Subjects completed a self-assessment of respiratory symptoms, pulmonary function testing, and 6MWD testing as well as a chest computed tomography to determine emphysema severity. We used regression models to determine the association of emphysema with respiratory symptoms and 6MWD in HIV+ subjects and compared this to HIV- subjects. RESULTS: Models stratified by HIV status demonstrated an association between >10% radiographic emphysema and chronic cough and/or phlegm and 6MWD in HIV+ subjects. These associations persisted among the subset without airflow obstruction: those with emphysema had 4.2 (95% confidence interval: 1.3 to 14) times the odds of chronic cough and/or phlegm and walked 60 m (95% confidence interval: 26 to 93) less distance than those without emphysema. There was no association between >10% emphysema and symptoms or 6MWD in HIV- subjects. CONCLUSIONS: In our cohort, >10% radiographic emphysema was associated with chronic cough and/or phlegm and lower 6MWD in HIV+ but not HIV- subjects. These findings were robust even among HIV+ subjects with milder forms of emphysema and those without airflow obstruction, highlighting the clinical impact of emphysema in these patients. PMID- 27716731 TI - Health and survival of HIV perinatally exposed but uninfected children born to HIV-infected mothers. AB - PURPOSE OF REVIEW: The number of HIV-exposed but uninfected (HEU) infants exposed to both HIV and multiple antiretroviral drugs in utero and during prolonged breastfeeding is increasing in low-income countries where HIV prevalence is the highest. We review recent evidence on the effects of perinatal/postnatal exposure to maternal HIV and combined antiretroviral therapy (cART) on health outcomes of HEU children (mitochondrial and metabolic toxicity, adverse pregnancy outcomes, neurodevelopment, growth, infectious morbidity, and mortality). RECENT FINDINGS: Several studies have reported ART-associated mitochondrial toxicity and metabolic disorders with conflicting results on adverse pregnancy outcomes, underscoring the need to conduct further investigations on these questions. Studies about congenital abnormalities report no significant differences between HEU exposed to ART and HIV-unexposed (HUU) children. Updated French data showed no significant difference in cancer incidence between HEU cART-exposed children and the general paediatric population. Furthermore, HEU children exposed to maternal cART have modest but significant impairment of development and a higher risk of growth impairment. Finally, HEU have higher risks of infections (mainly low respiratory tract infections and diarrhoea) and malaria than HUU children, particularly in children not breastfed or after early weaning. Higher mortality risk from infectious disease is reported in HEU compared to HUU children. SUMMARY: As we move toward the elimination of mother-to-child transmission of HIV, HEU children are an emerging population whose health outcomes remain to be fully described. Future large cohorts of HEU children using careful comparison groups of HUU in the post-ART era are needed to better understand their long-term health outcomes. PMID- 27716732 TI - Effect of coinfection with hepatitis C virus on survival of individuals with HIV 1 infection. AB - PURPOSE OF REVIEW: Hepatitis C virus (HCV) coinfection is a common and an important comorbidity in HIV infection. We review current trends in mortality and the potential for early combination antiretroviral therapy (cART) and HCV therapy to improve survival in coinfected patients. RECENT FINDINGS: HIV/HCV coinfection increases risk of death from all causes, and from liver disease and harmful drug use in particular. There is growing evidence for a direct role of HIV in liver fibrogenesis and for cART to decrease the risk of dying from liver disease in coinfected persons. Sustained virologic responses after HCV treatment greatly impact mortality by reducing rates of hepatic decompensation, hepatocellular carcinoma and death from liver-related and nonliver-related causes by at least 50%, but treatment uptake has been low so far. Recent epidemiologic studies do suggest that liver-related mortality is declining in recent calendar periods; however, methodological limitations of currently available studies are important. SUMMARY: Early cART and wider HCV treatment have the potential to markedly reduce HCV-related mortality and thus increase survival overall for HIV-infected populations. However, HCV treatment will need to be greatly scaled up. Given the complex nature of the populations affected, future studies will need to be carefully designed and controlled to rigorously evaluate the impact of these revolutionary therapies on survival. PMID- 27716730 TI - Survival of HIV-1 vertically infected children. AB - PURPOSE OF REVIEW: It is 20 years since the start of the combination antiretroviral therapy (cART) era and more than 10 years since cART scale-up began in resource-limited settings. We examined survival of vertically HIV infected infants and children in the cART era. RECENT FINDINGS: Good survival has been achieved on cART in all settings with up to 10-fold mortality reductions compared with before cART availability. Although mortality risk remains high in the first few months after cART initiation in young children with severe disease, it drops rapidly thereafter even for those who started with advanced disease, and longer term mortality risk is low. However, suboptimal retention on cART in routine programs threatens good survival outcomes and even on treatment children continue to experience high comorbidity risk; infections remain the major cause of death. Interventions to address infection risk include a cotrimoxazole prophylaxis, isoniazid preventive therapy, routine childhood and influenza immunization, and improving maternal survival. SUMMARY: Pediatric survival has improved substantially with cART and HIV-infected children are aging into adulthood. It is important to ensure access to diagnosis and early cART, good program retention as well as optimal comorbidity prophylaxis and treatment to achieve the best possible long-term survival and health outcomes for vertically infected children. PMID- 27716734 TI - Lessons from acute HIV infection. AB - PURPOSE OF REVIEW: Understanding the characteristics of transmission during acute HIV infection (AHI) may inform targets for vaccine-induced immune interdiction. Individuals treated in AHI with a small HIV reservoir size may be ideal candidates for therapeutic HIV vaccines aiming for HIV remission (i.e. viremic control after treatment interruption). RECENT FINDINGS: The AHI period is brief and peak viremia predicts a viral set point that occurs 4-5 weeks following infection. Robust HIV-specific CD8 T-cell responses lower viral set points. Phylogenetic analyses of founder viruses demonstrated unique bottleneck selections and specific genetic signatures to optimize for high-fitness variants and successful transmission events. HIV clades, route of transmission and the presence of minor variants may affect vaccine protection. Antiretroviral treatment in AHI results in smaller HIV reservoir size, better CD4 T-cell recovery and fewer virus escapes. SUMMARY: The knowledge of untreated and treated AHI informs the development of vaccines, in that preventive vaccines will require broad coverage for multiple clades and antigenic variants associated with unique bottleneck selections. Vaccines that help the host to control viremia could minimize onward transmission. Therapeutic HIV vaccines aimed at HIV remission should be studied in early-treated individuals who have few or no viral escape mutants and a more preserved immune system. PMID- 27716735 TI - Glaucocalyxin A Ameliorates Myocardial Ischemia-Reperfusion Injury in Mice by Suppression of Microvascular Thrombosis. AB - BACKGROUND The aim of this study was to evaluate the cardio-protective roles of glaucocalyxin A (GLA) in myocardial ischemia-reperfusion injury and to explore the underlying mechanism. MATERIAL AND METHODS Myocardial ischemia-reperfusion in wild-type C57BL/6J mice was induced by transient ligation of the left anterior descending artery. GLA or vehicle (solvent) was administrated intraperitoneally to the mice before reperfusion started. After 24 h of myocardial reperfusion, ischemic size was revealed by Evans blue/TTC staining. Cardiac function was evaluated by echocardiography and microvascular thrombosis was assessed by immunofluorescence staining of affected heart tissue. We also measured the phosphorylation of AKT, ERK, P-GSK-3beta, and cleaved caspase 3 in the myocardium. RESULTS Compared to the solvent-treated control group, GLA administration significantly reduced infarct size (GLA 13.85+/-2.08% vs. Control 18.95+/-0.97%, p<0.05) and improved left ventricular ejection fraction (LVEF) (GLA 53.13+/-1.11% vs. Control 49.99+/-1.25%, p<0.05) and left ventricular fractional shortening (LVFS) (28.34+/-0.71% vs. Control 25.11+/-0.74%, p<0.05) in mice subjected to myocardial ischemia-reperfusion. GLA also attenuated microvascular thrombosis (P<0.05) and increased the phosphorylation of pro survival kinase AKT (P<0.05) and GSK-3beta (P<0.05) in the myocardium upon reperfusion injury. CONCLUSIONS Administration of GLA before reperfusion ameliorates myocardial ischemia-reperfusion injury in mice. The cardio-protective roles of GLA may be mediated through the attenuation of microvascular thrombosis. PMID- 27716736 TI - Banding ligation or beta-blockers for primary prevention of variceal bleeding? AB - Variceal bleeding is one of the most serious complications of liver cirrhosis. Nonselective beta-blockers and endoscopic ligation are considered effective strategies for primary prevention of variceal bleeding, but there is no consensus about which alternative constitutes the best option. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified seven systematic reviews including 21 randomized controlled trials addressing the question of this article. We combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded variceal ligation probably decreases the risk of variceal bleeding and it is associated to less adverse effects when compared with nonselective beta blockers, although probably there is no difference in terms of mortality.

AB - The discovery that the bacterium Helicobacter pylori (H. pylori) lives in the stomach has rendered out-of-date the concept of inhospitality of the gastric environment. H. pylori is able to survive in this organ through mechanisms of acid resistance and colonization factors. The prevalence of H. pylori infection varies depending on age, socioeconomic class, and country. Currently, in the context of a decreased trend in H. pylori prevalence, it is estimated that about 50% of the world's human population are carriers of the microorganism, with a higher rate in developing countries than in developed countries. In this review, the authors provide an overview on the current status of knowledge on the clinical aspects of H. pylori infection, with a focus on diagnostic and therapeutic challenges. In particular, the choice of the test to diagnose H. pylori infection, defined as invasive or non-invasive based on the need or not of biopsy specimens obtained during an endoscopy, depends on the clinical context. Regarding bacterial eradication, it is important that treatment should be decided locally on the basis of local antibiotic usage, documented antibiotic resistance and outcome data. For patients having previously received a clarithromycin containing regimen, this drug should be avoided as a second-line therapy. In this case, the tailored therapy (to test clarithromycin susceptibility before prescribing drugs) or the so-called quadruple therapy, and triple levofloxacin based therapy should be proposed. Rifabutin- and furazolidone-based treatments should be reserved for further treatment. PMID- 27716739 TI - The effect of a functional appliance in the management of temporomandibular joint disorders in patients with juvenile idiopathic arthritis. AB - BACKGROUND: Patients affected by juvenile idiopathic arthritis (JIA) may have several craniofacial growth disturbances and involvements at the temporomandibular joint (TMJ). The objectives of the present study were to evaluate the clinical effectiveness of functional therapy used to reduce asymmetry of mandibular growth and TMJ disorder in patients with JIA. METHODS: By a retrospective longitudinal design, a cohort of 54 patients with JIA (mean age, 13.2+/-3.7 years; range, 5-17.7 years) and with TMJ involvements was enrolled in the study. Each patient, following the collection of clinical parameters, was treated for 24 months with a functional appliance individually customized by acrylic resin and resilient stainless steel with posterior and anterior metallic bite planes preventing the teeth from intercuspal contact. To evaluate differences before (T0) and after therapy (T1) of the clinical TMJ parameters, the statistical analysis by the chi2 Test was performed. RESULTS: All the patients completed successfully the study. In patients with JIA, the use of a functional appliance determined a statistically significant difference of the pain during jaw movement, maximal mouth opening, TMJ sounds and crepitations (P<0.001) and TMJ click, significantly reduced at T1 (P<0.05). CONCLUSIONS: The use of an orthodontic functional appliance determined a significant improvement, at 24 months, in many TMJ signs and symptoms in patients affected by JIA and with TMJ disorders. This study suggests that children and adolescents with JIA which presented either unilateral or bilateral moderate to severe TMJ involvement, if not treated, should be develop severe disturbances during growing.

AB - Periostin is an extracellular matrix protein that is implicated in the biology of normal bone remodeling and in different cancer cell growth and metastasis. However, there is no information on the role of periostin in multiple myeloma (MM). Thus, we evaluated periostin in six myeloma cell lines in vitro; in the bone marrow plasma and serum of 105 newly diagnosed symptomatic MM (NDMM) patients and in the serum of 23 monoclonal gammopathy of undetermined significance (MGUS), 33 smoldering MM (SMM) patients, 30 patients at the plateau phase post-first-line therapy, 30 patients at first relapse and 30 healthy controls. We found high levels of periostin in the supernatants of myeloma cell lines compared with ovarian cancer cell lines that were not influenced by the incubation with the stromal cell line HS5. In NDMM patients the bone marrow plasma periostin was almost fourfold higher compared with the serum levels of periostin and correlated with the presence of fractures and of diffuse magnetic resonance imaging pattern of marrow infiltration. Serum periostin was elevated in NDMM patients compared with healthy controls, MGUS and SMM patients and correlated with advanced disease stage, high lactate dehydrogenase, increased activin-A, increased bone resorption and reduced bone formation. Patients at first relapse had also elevated periostin compared with healthy controls, MGUS and SMM patients, while even patients at the plateau phase had elevated serum periostin compared with healthy controls. These results support an important role of periostin in the biology of myeloma and reveal periostin as a possible target for the development of antimyeloma drugs.

PMID- 27716741 TI - Expression of CALR mutants causes mpl-dependent thrombocytosis in zebrafish. AB - CALR mutations are identified in about 30% of JAK2/MPL-unmutated myeloproliferative neoplasms (MPNs) including essential thrombocythemia (ET) and primary myelofibrosis. Although the molecular pathogenesis of CALR mutations leading to MPNs has been studied using in vitro cell lines models, how mutant CALR may affect developmental hematopoiesis remains unknown. Here we took advantage of the zebrafish model to examine the effects of mutant CALR on early hematopoiesis and model human CALR-mutated MPNs. We identified three zebrafish genes orthologous to human CALR, referred to as calr, calr3a and calr3b. The expression of CALR-del52 and CALR-ins5 mutants caused an increase in the hematopoietic stem/progenitor cells followed by thrombocytosis without affecting normal angiogenesis. The expression of CALR mutants also perturbed early developmental hematopoiesis in zebrafish. Importantly, morpholino knockdown of mpl but not epor or csf3r could significantly attenuate the effects of mutant CALR. Furthermore, the expression of mutant CALR caused jak-stat signaling activation in zebrafish that could be blocked by JAK inhibitors (ruxolitinib and fedratinib). These findings showed that mutant CALR activates jak-stat signaling through an mpl-dependent mechanism to mediate pathogenic thrombopoiesis in zebrafish, and illustrated that the signaling machinery related to mutant CALR tumorigenesis are conserved between human and zebrafish.

AB - Members of the p53 tumor-suppressor family are expressed as multiple isoforms. Isoforms with an N-terminal transactivation domain are transcriptionally active, while those ones lacking this domain often inhibit the transcriptional activity of other family members. In squamous cell carcinomas, the high expression level of DeltaNp63alpha inhibits the tumor-suppressor function of TAp73beta. This can in principle be due to blocking of the promoter or by direct interaction between both proteins. p63 and p73 can hetero-oligomerize through their tetramerization domains and a hetero-tetramer consisting of two p63 and two p73 molecules is thermodynamically more stable than both homo-tetramers. Here we show that cells expressing both p63 and p73 exist in mouse epidermis and hair follicle and that hetero-tetramer complexes can be detected by immunoprecipitation in differentiating keratinocytes. Through structure determination of the hetero tetramer, we reveal why this hetero-tetramer is the thermodynamically preferred species. We have created mutants that exclusively form either hetero-tetramers or homo-tetramers, allowing to investigate the function of these p63/p73 hetero tetramers. Using these tools, we show that inhibition of TAp73beta in squamous cell carcinomas is due to promoter squelching and not direct interaction. PMID- 27716745 TI - The degradation of EZH2 mediated by lncRNA ANCR attenuated the invasion and metastasis of breast cancer. AB - EZH2 (the Enhancer of Zeste Homolog 2), as a key epigenetic regulator and EMT inducer, participates in a variety of cancer metastasis. EZH2 stability is regulated by several types of post-translational modifications (PTMs).The long non-coding RNAs (lncRNA) have been implicated to have critical roles in multiple carcinogenesis through a wide range of mechanisms, including modulating the stability of proteins. To date, whether the stability of EZH2 protein is regulated by lncRNAs remains unexplored. Here we report the discovery of ANCR modulating the stability of EZH2, and hence in the invasion and metastasis of breast cancer cells. We determined that ANCR potentiated the CDK1-EZH2 interaction, which then increased the intensity of phosphorylation at Thr-345 and Thr-487 sites of EZH2, facilitating EZH2 ubiquitination and hence its degradation. Moreover, we also uncover ANCR is an important player in breast cancer progression and metastasis mainly through decreasing EZH2 stability. More specifically, we initially found that ANCR level was lower in breast cancer tissues and breast cancer cell lines, in contrast to their normal counterparts. We then demonstrated that knockdown of ANCR induced an EMT program and promoted cell migration and invasion in MCF10A (epithelial cells), whereas ectopic expression of ANCR repressed breast cancer cells migration and invasion. Furthermore, we validated in a nude mouse model that overexpression of ANCR in highly malignant and invasive MDA-MB-231 breast cancer cells significantly reduced the ability of the cells to form tumors and prevented the lung metastasis in vivo. Based on these data, our findings define a new mechanism underlying modulation of EZH2 stability by linking ANCR interaction with EZH2 to promote its phosphorylation that facilitates EZH2 degradation and suppresses breast cancer progression.

PMID- 27716746 TI - Structural and molecular changes in the aging choroid: implications for age related macular degeneration. AB - Age-related macular degeneration (AMD) is a devastating disease-causing vision loss in millions of people around the world. In advanced stages of disease, death of photoreceptor cells, retinal pigment epithelial cells, and choroidal endothelial cells (CECs) are common. Loss of endothelial cells of the choriocapillaris is one of the earliest detectable events in AMD, and, because the outer retina relies on the choriocapillaris for metabolic support, this loss may be the trigger for progression to more advanced stages. Here we highlight evidence for loss of CECs, including changes to vascular density within the choriocapillaris, altered abundance of CEC markers, and changes to overall thickness of the choroid. Furthermore, we review the key components and functions of the choroid, as well as Bruch's membrane, both of which are vital for healthy vision. We discuss changes to the structure and molecular composition of these tissues, many of which develop with age and may contribute to AMD pathogenesis. For example, a crucial event that occurs in the aging choriocapillaris is accumulation of the membrane attack complex, which may result in complement mediated CEC lysis, and may be a primary cause for AMD-associated choriocapillaris degeneration. The actions of elevated monomeric C-reactive protein in the choriocapillaris in at-risk individuals may also contribute to the inflammatory environment in the choroid and promote disease progression. Finally, we discuss the progress that has been made in the development of AMD therapies, with a focus on cell replacement. PMID- 27716749 TI - Reply to 'Can photoreceptor loss also account for changes in pupil size following panretinal photocoagulation?' PMID- 27716751 TI - Hormone-replacement therapy: current thinking. AB - For several decades, the role of hormone-replacement therapy (HRT) has been debated. Early observational data on HRT showed many benefits, including a reduction in coronary heart disease (CHD) and mortality. More recently, randomized trials, including the Women's Health Initiative (WHI), studying mostly women many years after the the onset of menopause, showed no such benefit and, indeed, an increased risk of CHD and breast cancer, which led to an abrupt decrease in the use of HRT. Subsequent reanalyzes of data from the WHI with age stratification, newer randomized and observational data and several meta-analyses now consistently show reductions in CHD and mortality when HRT is initiated soon after menopause. HRT also significantly decreases the incidence of various symptoms of menopause and the risk of osteoporotic fractures, and improves quality of life. In younger healthy women (aged 50-60 years), the risk-benefit balance is positive for using HRT, with risks considered rare. As no validated primary prevention strategies are available for younger women (<60 years of age), other than lifestyle management, some consideration might be given to HRT as a prevention strategy as treatment can reduce CHD and all-cause mortality. Although HRT should be primarily oestrogen-based, no particular HRT regimen can be advocated. PMID- 27716750 TI - Risk of geographic atrophy in age-related macular degeneration patients treated with intravitreal anti-VEGF agents. AB - Anti-vascular endothelial growth factor (VEGF) intravitreal agents are the only successful treatment for wet age-related macular degeneration (AMD). However, there are emerging signals that anti-VEGF treatment can potentially increase development of geographic atrophy (GA). Histopathologic, animal, and clinical studies support this hypothesis although direct proof of a relationship between GA and use of anti-VEGF agents in neovascular AMD is not yet established. This review presents current evidence supporting an association between anti-VEGF therapy and progression of geographic atrophy. The need of exploring alternative methods of treating AMD is indirectly but clearly emphasized. PMID- 27716752 TI - Diabetes: Steno-2 - a small study with a big heart.

AB - OBJECTIVE: To describe the frequency and antiparasitic in vitro susceptibility of Blastocystis hominis in patients admitted to theHospital Regional Lambayeque, Peru. MATERIAL AND METHODS: A cross-sectional study was conducted from January to August 2015 at 313 patients of all ages. B. hominis detection was performed on serial fecal samples by direct microscopic examination and microculture in modified Locke solution. The in vitro susceptibility testing against the drug metronidazole, nitazoxanide, trimethoprim-sulfamethoxazole and erythromycin was performed in 24 strains of B. hominis, which grew up (microculture method) in 10 double concentrations of each antimicrobial (from 256 ug/ml to 0.5 ug/mL) plus a control. RESULTS: 46.3% (145/313) of the sample had B. hominis, also the age between 12 to 17 years and 60 years was associated with higher frequency of parasites (OR: 2.93 and 2.62). The minimum inhibitory concentration (MIC) 90 of metronidazole and nitazoxanide was 3.19 ug/mL and 11.19 ug/ml, respectively, whereas the MIC 90 of trimethoprim-sulfamethoxazole and erythromycin were above 256 ug/mL. CONCLUSIONS: B. hominis occurs in high frequency in patients admitted to the Hospital Regional in Lambayeque, proving to be an important problem of public health in the region. Also B. hominis isolated from these patients were shown to be susceptible in vitro to low concentrations of metronidazole and nitazoxanide so they could be chosen for treatment of this parasite.

AB - OBJECTIVE: We present a descriptive analysis of our cases of sphincterotomy followed by papillary large balloon dilation in a single session (ES-LBD) in the management of difficult to extract calculi, with the objective of assessing rates of therapeutic success and complications in local experience. MATERIAL AND METHODS: ERCP procedures with ES-LBD performed for choledocholithiasis between January 2009 and December 2014 in patients older than 18 years and without preexistent sphincterotomy were selected from records of the Gastroenterology Service at Cayetano Heredia National Hospital. A descriptive analysis of therapeutic success and complications was performed. RESULTS: 73 procedures in 73 patients were included (65.8% female, 34.2% male). Patient's average age was 59.4+/-19.8 years. Average diameter of calculi was 14.6+/-3.3mm. Average diameter of dilations was 14.6+/-2.27 mm. In 8 cases mechanical lithotripsy was performed. Complete calculi extraction was achieved in 56 procedures (76.7%). Complications occurred in 4 cases (5.5%). There were no deaths. CONCLUSION: Our figures of therapeutic success and complications with ES-LBD for difficult to extract calculi are similar to those reported in literature. ES-LBD is an effective and safe technique for management of choledocholithiasis. PMID- 27716753 TI - Mitochondrial disease and endocrine dysfunction. AB - Mitochondria are critical organelles for endocrine health; steroid hormone biosynthesis occurs in these organelles and they provide energy in the form of ATP for hormone production and trafficking. Mitochondrial diseases are multisystem disorders that feature defective oxidative phosphorylation, and are characterized by enormous clinical, biochemical and genetic heterogeneity. To date, mitochondrial diseases have been found to result from >250 monogenic defects encoded across two genomes: the nuclear genome and the ancient circular mitochondrial genome located within mitochondria themselves. Endocrine dysfunction is often observed in genetic mitochondrial diseases and reflects decreased intracellular production or extracellular secretion of hormones. Diabetes mellitus is the most frequently described endocrine disturbance in patients with inherited mitochondrial diseases, but other endocrine manifestations in these patients can include growth hormone deficiency, hypogonadism, adrenal dysfunction, hypoparathyroidism and thyroid disease. Although mitochondrial endocrine dysfunction frequently occurs in the context of multisystem disease, some mitochondrial disorders are characterized by isolated endocrine involvement. Furthermore, additional monogenic mitochondrial endocrine diseases are anticipated to be revealed by the application of genome-wide next generation sequencing approaches in the future. Understanding the mitochondrial basis of endocrine disturbance is key to developing innovative therapies for patients with mitochondrial diseases.

AB - OBJECTIVE: To identify sociodemographic, clinical, and endoscopic characteristics in patients with inflammatory bowel disease (IBD). MATERIALS AND METHODS: The study period was from January 2004 to December 2014. The final diagnosis was determined by clinical gastroenterologists experienced in the diagnosis and management of IBD, based on internationally accepted diagnostic criteria. RESULTS: 105 patients with IBD were studied, 77% with ulcerative colitis (UC) and 23% with Crohn's disease (CD). The average age of initial diagnosis for UC and CD was 53.02 and 57.7 years, respectively. Regarding the gender distribution, the male:female ratio was 1.3:1 for UC and 2:1 for CD. Predominant clinical manifestations were: diarrhea (76.5%) in CU and lower gastrointestinal bleeding / abdominal pain (66.6% for each symptom) in EC. The predominant form of presentation was moderate for both CU (49.3%) and EC (62.5%). 47% of patients with UC had extensive colitis and 54.2% of patients with CD had Ileocolitis. 6.2% of the UC patients underwent surgery, whereas 50% of the CD patients required it. CONCLUSIONS: There is a tendency to an increased detection of cases of Crohn's disease in our country and in Latin America with respect to previous studies. There is a prevalence of moderate forms of presentation for both UC and CD, and high percentages of surgery in EC is evident.

AB - OBJECTIVE: To determine the effect of treatment with honey in piroxicam-induced gastric ulcer in Holtzman rats. MATERIALS AND METHODS: 48 eight-week old female Holtzman rats, weights between 100 and 200 grams, were divided into 6 treatment groups as follow: Group A: water; Group B: piroxicam (30 mg/kg); Group C: omeprazole (5 mg/kg) and piroxicam (30 mg/kg); Group D: honey (2.5 g/kg) and piroxicam (30 mg/kg); Group E: honey (5 g/kg) and piroxicam (30 mg/kg); Group F: honey (7.5 g/kg) and piroxicam (30 mg/kg). Macroscopic studies, using Scion Image, and microscopic histological section of gastric mucosa were performed after the interventions. RESULTS: The results of the macroscopic studies showed statistically significant differences for both doses of honey at 6 g/kg and 7.5 g/kg when compared to piroxicam (p=0.016 and p=0.001 respectively) and the gastroprotective effect was similar when compared to omeprazole (p>0.05). Microscopic studies showed statistically significant differences only for dose at 7.5 g/kg when compared to piroxicam (p=0.0018) and the gastroprotective effect was similar to omeprazole (p=1). CONCLUSION: Dose of honey at 7.5 g/kg showed gastroprotective effect at microscopic and macroscopic studies when compared to omeprazole.

AB - BACKGROUND: Hydrogen breath tests (HBT) are used to confirm the diagnosis of carbohydrate intolerance or small intestinal bacterial overgrowth (SIBO). OBJECTIVE: Determine the existence of a correlation between the presence and intensity of symptoms experimented by the patient after the ingestion of a carbohydrate load and the test result. MATERIALS AND METHODS: This is an observational, retrospective and analytic study, in which all patients' files from year 2008 to 2014 containing a report of a HBT performed at Hospital San Jose TEC de Monterrey were revised. Using a visual analogue scale (VAS), the patient reported the intensity of gastrointestinal symptoms during the test. Descriptive statistics were obtained, and exclusively for lactose HBTs, Pearson's correlation coefficient (r) between maximum hydrogen concentration in breath and symptom intensity was calculated. RESULTS: A HBT was performed in 33 patients: 23 with lactose, 5 with fructose, and 5 with lactulose as substrate. Of these, 10, 2, and 5 tests were positive, respectively. For lactose HBTs, the symptom with most sensitivity was flatulence (80%), which also had the greatest likelihood ratio for a positive test (1.73). Diarrhea had the greatest specificity (84.6%). A tendency for positivity was observed when patients presented symptoms. A moderately positive correlation between hydrogen ppm and symptom intensity was found (r=0.427, p=0.023). CONCLUSIONS: A correlation between symptom intensity and test positivity was found in patients with lactose intolerance. The presence of flatulence after lactose loading may be indicative of a positive test. PMID- 27716761 TI - [A current perspective of natural orifices transluminal endoscopic surgery (NOTES)]. AB - Natural orifice transluminal endoscopic surgery (NOTES) represents an alternative in surgical approach, combined with the progress and experience gained from conventional and endoscopic surgery. Bibliographic research in PubMed, Medline database from 2000 to 2015 and analysis of the literature reviews found. NOTES provides vision and natural orifice approach, it has optimized operating times as well as reduced complications and better cosmetic results. Small series of patients have been reported, but there is not a valid clinical multicenter study by evidence-based medicine. NOTES can help to improve the standard operations, complemented with laparoscopic surgery rather than replace it and thus develop tools for the resolution of various diseases that require surgical treatment. This option in current surgery is safe and presents satisfactory results in the reported cases. The development of this new approach of performing surgical procedures requires further study and development of new technology in order to increase the accessibility of these procedures and represent in a practical and sustained way, a better option to approach surgical pathology.

AB - Exposure to potentially toxic substances represents 0.3% of annual visits to a pediatric emergency department, being a situation likely to be prevented and that generates a non-negligible morbidity and mortality. The most common route of exposure is the oral and drugs are the products most frequently involved. Esophagitis caustic ingestion of corrosive substances in childhood is now a public health problem in developing countries. Clinical manifestations vary from no injuries serious commitment to high risk of death observed more frequently in patients between one and three years old. In addition to drilling, the most severe complication of esophagitis is caustic stricture formation, which occurs at a frequency of 5% to 47% in severe cases. The role of systemic corticosteroids in preventing caustic esophageal stenosis is still considered controversial, despite the many published reports showing your benefit. We report two cases of pediatric patients with caustic esophagitis IIB Zargar who received systemic corticosteroids with favorable evolution.

Hydatid cysts are commonly located in the liver and lung. Pancreas affection is very rare even in endemic areas. CASE REPORT: 36-year-old female with the suspicion of hydatid disease of the pancreas 5 years before her admission. The patient gave history of epigastric pain and weight lose. CT scan and MRI showed a cystic lesion of the tail of the pancreas and the diagnosis of hydatid disease was confirmed with ELIZA and Western Blot. The patient underwent a laparoscopic distal spleno pancreatectomy. The recovery was uneventful. CONCLUSION: Hydatid disease must be considered in the differential diagnosis of the cystic lesions of the pancreas, especially in patients who come from endemic areas.

AB - Neuroectodermal tumours are characterized by aberrant processing of disialogangliosides concomitant with high expression of GD2 or GD3 on cell surfaces. Antibodies targeting GD2 are already in clinical use for therapy of neuroblastoma, a solid tumour of early childhood. Here, we set out to identify peptides with high affinity to human disialoganglioside GD2. To this end, we performed a combined in vivo and in vitro screen using a recombinant phage displayed peptide library. We isolated a phage displaying the peptide sequence WHWRLPS that specifically binds to the human disialoganglioside GD2. Binding specificity was confirmed by mutational scanning and by comparative analyses using structurally related disialogangliosides. In vivo, significant enrichment of phage binding to xenografts of human neuroblastoma cells in mice was observed. Tumour-specific phage accumulation could be blocked by intravenous coinjection of the corresponding peptide. Comparative pharmacokinetic analyses revealed higher specific accumulation of 68Ga-labelled GD2-binding peptide compared to 111In labelled peptide in xenografts of human neuroblastoma. In contrast to 124I-MIBG, which is currently evaluated as a neuroblastoma marker in PET/CT, 68Ga-labelled GD2-specific peptide spared the thyroid but was enriched in the kidneys, which could be partially blocked by infusion of amino acids.In summary, we here report on a novel tumour-homing peptide that specifically binds to the disialoganglioside GD2, accumulates in xenografts of neuroblastoma cells in mice and bears the potential for tumour detection using PET/CT. Thus, this peptide may serve as a new scaffold for diagnosing GD2-positive tumours of neuroectodermal origin. PMID- 27716772 TI - The Beta-1-Receptor Blocker Nebivolol Elicits Dilation of Cerebral Arteries by Reducing Smooth Muscle [Ca2+]i. AB - RATIONALE: Nebivolol is known to have beta-1 blocker activity, but it was also suggested that it elicits relaxation of the peripheral arteries in part via release of nitric oxide (NO). However, the effect of nebivolol on the vasomotor tone of cerebral arteries is still unclear. OBJECTIVE: To assess the effects of nebivolol on the diameter of isolated rat basilar arteries (BA) in control, in the presence of inhibitors of vasomotor signaling pathways of know action and hemolysed blood. METHODS AND RESULTS: Vasomotor responses were measured by videomicroscopy and the intracellular Ca2+ by the Fura-2 AM ratiometric method. Under control conditions, nebivolol elicited a substantial dilation of the BA (from 216+/-22 to 394+/-20 MUm; p<0.05) in a concentration-dependent manner (10-7 to 10-4 M). The dilatation was significantly reduced by endothelium denudation or by L-NAME (inhibitor of NO synthase) or by SQ22536 (adenylyl cyclase blocker). Dilatation of BA was also affected by beta-2 receptor blockade with butoxamine, but not by the guanylate cyclase blocker ODQ. Interestingly, beta-1 blockade by atenolol inhibited nebivolol-induced dilation. Also, the BKCa channel blocker iberiotoxin and KCa channel inhibitor TEA significantly reduced nebivolol-induced dilation. Nebivolol significantly reduced smooth muscle Ca2+ level, which correlated with the increases in diameters and moreover it reversed the hemolysed blood-induced constriction of BA. CONCLUSIONS: Nebivolol seems to have an important dilator effect in cerebral arteries, which is mediated via several vasomotor mechanisms, converging on the reduction of smooth muscle Ca2+ levels. As such, nebivolol may be effective to improve cerebral circulation in various diseased conditions, such as hemorrhage. PMID- 27716773 TI - Enhanced Mitogenic Activity of Recombinant Human Vascular Endothelial Growth Factor VEGF121 Expressed in E. coli Origami B (DE3) with Molecular Chaperones. AB - We describe the production of a highly-active mutant VEGF variant, alpha2-PI1-8 VEGF121, which contains a substrate sequence for factor XIIIa at the aminoterminus designed for incorporation into a fibrin gel. The alpha2-PI1-8 VEGF121 gene was synthesized, cloned into a pET-32a(+) vector and expressed in Escherichia coli Origami B (DE3) host cells. To increase the protein folding and the solubility, the resulting thioredoxin-alpha2-PI1-8-VEGF121 fusion protein was co-expressed with recombinant molecular chaperones GroES/EL encoded by independent plasmid pGro7. The fusion protein was purified from the soluble fraction of cytoplasmic proteins using affinity chromatography. After cleavage of the thioredoxin fusion part with thrombin, the target protein was purified by a second round of affinity chromatography. The yield of purified alpha2-PI1-8 VEGF121 was 1.4 mg per liter of the cell culture. The alpha2-PI1-8-VEGF121 expressed in this work increased the proliferation of endothelial cells 3.9-8.7 times in comparison with commercially-available recombinant VEGF121. This very high mitogenic activity may be caused by co-expression of the growth factor with molecular chaperones not previously used in VEGF production. At the same time, alpha2-PI1-8-VEGF121 did not elicit considerable inflammatory activation of human endothelial HUVEC cells and human monocyte-like THP-1 cells. PMID- 27716774 TI - Ontogeny of Unstable Chromosomes Generated by Telomere Error in Budding Yeast. AB - DNA replication errors at certain sites in the genome initiate chromosome instability that ultimately leads to stable genomic rearrangements. Where instability begins is often unclear. And, early instability may form unstable chromosome intermediates whose transient nature also hinders mechanistic understanding. We report here a budding yeast model that reveals the genetic ontogeny of genome rearrangements, from initial replication error to unstable chromosome formation to their resolution. Remarkably, the initial error often arises in or near the telomere, and frequently forms unstable chromosomes. Early unstable chromosomes may then resolve to an internal "collection site" where a dicentric forms and resolves to an isochromosome (other outcomes are possible at each step). The initial telomere-proximal unstable chromosome is increased in mutants in telomerase subunits, Tel1, and even Rad9, with no known telomere specific function. Defects in Tel1 and in Rrm3, a checkpoint protein kinase with a role in telomere maintenance and a DNA helicase, respectively, synergize dramatically to generate unstable chromosomes, further illustrating the consequence of replication error in the telomere. Collectively, our results suggest telomeric replication errors may be a common cause of seemingly unrelated genomic rearrangements located hundreds of kilobases away. PMID- 27716775 TI - Mechano-chemical Interactions in Cardiac Sarcomere Contraction: A Computational Modeling Study. AB - We developed a model of cardiac sarcomere contraction to study the calcium tension relationship in cardiac muscle. Calcium mediates cardiac contraction through its interactions with troponin (Tn) and subsequently tropomyosin molecules. Experimental studies have shown that a slight increase in intracellular calcium concentration leads to a rapid increase in sarcomeric tension. Though it is widely accepted that the rapid increase is not possible without the concept of cooperativity, the mechanism is debated. We use the hypothesis that there exists a base level of cooperativity intrinsic to the thin filament that is boosted by mechanical tension, i.e. a high level of mechanical tension in the thin filament impedes the unbinding of calcium from Tn. To test these hypotheses, we developed a computational model in which a set of three parameters and inputs of calcium concentration and sarcomere length result in output tension. Tension as simulated appeared in good agreement with experimentally measured tension. Our results support the hypothesis that high tension in the thin filament impedes Tn deactivation by increasing the energy required to detach calcium from the Tn. Given this hypothesis, the model predicted that the areas with highest tension, i.e. closest to the Z-disk end of the single overlap region, show the largest concentration of active Tn's. PMID- 27716776 TI - A Dynamic Model of Post-Traumatic Stress Disorder for Military Personnel and Veterans. AB - Post-traumatic stress disorder (PTSD) stands out as a major mental illness; however, little is known about effective policies for mitigating the problem. The importance and complexity of PTSD raise critical questions: What are the trends in the population of PTSD patients among military personnel and veterans in the postwar era? What policies can help mitigate PTSD? To address these questions, we developed a system dynamics simulation model of the population of military personnel and veterans affected by PTSD. The model includes both military personnel and veterans in a "system of systems." This is a novel aspect of our model, since many policies implemented at the military level will potentially influence (and may have side effects on) veterans and the Department of Veterans Affairs. The model is first validated by replicating the historical data on PTSD prevalence among military personnel and veterans from 2000 to 2014 (datasets from the Department of Defense, the Institute of Medicine, the Department of Veterans Affairs, and other sources). The model is then used for health policy analysis. Our results show that, in an optimistic scenario based on the status quo of deployment to intense/combat zones, estimated PTSD prevalence among veterans will be at least 10% during the next decade. The model postulates that during wars, resiliency-related policies are the most effective for decreasing PTSD. In a postwar period, current health policy interventions (e.g., screening and treatment) have marginal effects on mitigating the problem of PTSD, that is, the current screening and treatment policies must be revolutionized to have any noticeable effect. Furthermore, the simulation results show that it takes a long time, on the order of 40 years, to mitigate the psychiatric consequences of a war. Policy and financial implications of the findings are discussed. PMID- 27716778 TI - Correction: Surveillance-Activated Defenses Block the ROS-Induced Mitochondrial Unfolded Protein Response. AB - [This corrects the article DOI: 10.1371/journal.pgen.1003346.]. PMID- 27716777 TI - Thioredoxin Inhibitors Attenuate Platelet Function and Thrombus Formation. AB - Thioredoxin (Trx) is an oxidoreductase with important physiological function. Imbalances in the NADPH/thioredoxin reductase/thioredoxin system are associated with a number of pathologies, particularly cancer, and a number of clinical trials for thioredoxin and thioredoxin reductase inhibitors have been carried out or are underway. Due to the emerging role and importance of oxidoreductases for haemostasis and the current interest in developing inhibitors for clinical use, we thought it pertinent to assess whether inhibition of the NADPH/thioredoxin reductase/thioredoxin system affects platelet function and thrombosis. We used small molecule inhibitors of Trx (PMX 464 and PX-12) to determine whether Trx activity influences platelet function, as well as an unbiased proteomics approach to identify potential Trx substrates on the surface of platelets that might contribute to platelet reactivity and function. Using LC-MS/MS we found that PMX 464 and PX-12 affected the oxidation state of thiols in a number of cell surface proteins. Key surface receptors for platelet adhesion and activation were affected, including the collagen receptor GPVI and the von Willebrand factor receptor, GPIb. To experimentally validate these findings we assessed platelet function in the presence of PMX 464, PX-12, and rutin (a selective inhibitor of the related protein disulphide isomerase). In agreement with the proteomics data, small molecule inhibitors of thioredoxin selectively inhibited GPVI-mediated platelet activation, and attenuated ristocetin-induced GPIb-vWF-mediated platelet agglutination, thus validating the findings of the proteomics study. These data reveal a novel role for thioredoxin in regulating platelet reactivity via proteins required for early platelet responses at sites of vessel injury (GPVI and GPIb). This work also highlights a potential opportunity for repurposing of PMX 464 and PX-12 as antiplatelet agents. PMID- 27716779 TI - Antibiotic Treatment and Length of Hospital Stay in Relation to Delivery Mode and Prematurity. AB - AIM: To investigate how 1) maternal delivery mode and 2) prematurity in infants are associated to antibiotic treatment and length of hospital stay. METHODS: Women having given birth and infants 0-12 months discharged from hospital between July 2005 and November 2011 were identified from the Swedish National Patient Register. Medical records were reviewed for 203 women and 527 infants. The risk ratio (RR) between antibiotic treatment and 1) delivery mode in women; 2) prematurity in infants was calculated. Length of stay and days of antibiotic therapy were compared by Wilcoxon rank-sum test. RESULTS: Women: There was an association between emergency caesarean section (CS) and antibiotic treatment (RR 5.0 95% confidence interval (CI) 2.2-11.5), but not for elective CS. Length of stay was longer for CS (emergency and elective) compared to vaginal delivery (p<0.01). Infants: RR for antibiotic treatment in preterm compared to term infants was 1.4 (95% CI 1.0-1.9). Length of stay (p<0.01), but not days of therapy (p = 0.17), was higher in preterm compared to term infants. CONCLUSION: We found that emergency CS increased the probability of maternal antibiotic treatment during hospitalisation, but no difference was found between term and preterm infants. The results are well aligned with current guidelines and may be considered in future studies on the effects of antibiotics. PMID- 27716780 TI - Complex Particulate Biomaterials as Immunostimulant-Delivery Platforms. AB - The control of infectious diseases is a major current challenge in intensive aquaculture. Most commercial vaccines are based on live attenuated or inactivated pathogens that are usually combined with adjuvants, oil emulsions being as the most widely used for vaccination in aquaculture. Although effective, the use of these oil emulsions is plagued with important side effects. Thus, the development of alternative safer and cost-effective immunostimulants and adjuvants is highly desirable. Here we have explored the capacity of inclusion bodies produced in bacteria to immunostimulate and protect fish against bacterial infections. Bacterial inclusion bodies are highly stable, non-toxic protein-based biomaterials produced through fully scalable and low-cost bio-production processes. The present study shows that the composition and structured organization of inclusion body components (protein, lipopolysaccharide, peptidoglycan, DNA and RNA) make these protein biomaterials excellent immunomodulators able to generically protect fish against otherwise lethal bacterial challenges. The results obtained in this work provide evidence that their inherent nature makes bacterial inclusion bodies exceptionally attractive as immunostimulants and this opens the door to the future exploration of this biomaterial as an alternative adjuvant for vaccination purposes in veterinary. PMID- 27716782 TI - Visualization of Anatomic Variation of the Anterior Septal Vein on Susceptibility Weighted Imaging. AB - BACKGROUND AND PURPOSE: Understanding the anatomy of the anterior septal vein (ASV) is critical for minimally invasive procedures to the third ventricle and for assessing lesion size and venous drainage in the anterior cranial fossa. Accordingly, this study evaluated topographic anatomy and anatomic variation of the ASV using susceptibility-weighted imaging (SWI). METHODS: Sixty volunteers were examined using a 3.0T MR system. The diameter of the ASV and distance between bilateral septal points were measured. ASVs were divided into types 1 (only drains frontal lobe) and 2 (drains both frontal lobe and head of the caudate nucleus). We evaluated the ASV-internal cerebral vein (ICV) junction based on its positional relationship with the appearance of a venous angle or a false venous angle and the foramen of Monro. Fused SW and T1-weighted images were used to observe positional relationships between the course of the ASV and the surrounding brain structures. RESULTS: The ASV and its small tributaries were clearly visualized in 120 hemispheres (100%). The average diameter of ASVs was 1.05+/-0.17 mm (range 0.9-1.6 mm). The average distance between bilateral septal points was 2.23+/-1.03 mm (range 1.3-6.6 mm). The ASV types 1 and 2 were in 77 (64.2%) and 43 (35.8%) hemispheres, respectively. In 83 (69.2%) hemispheres, the ASV-ICV junction was situated at the venous angle and the posterior margin of the foramen of Monro. In 37 (30.8%) hemispheres, the ASV-ICV junction was situated beyond the posterior margin of the foramen of Monro. The average distance between the posteriorly located ASV-ICV junction and the posterior margin of the foramen of Monro was 6.41+/-3.95 mm (range 2.4-15.9 mm). CONCLUSION: Using SWI, the topographic anatomy and anatomic variation of the ASV were clearly demonstrated. Preoperative assessment of anatomic variation of the ASV may be advantageous for minimally invasive neurosurgical procedures. PMID- 27716781 TI - Cross-Species Analysis of Gene Expression and Function in Prefrontal Cortex, Hippocampus and Striatum. AB - BACKGROUND: Mouse has been extensively used as a tool for investigating the onset and development of human neurological disorders. As a first step to construct a transgenic mouse model of human brain lesions, it is of fundamental importance to clarify the similarity and divergence of genetic background between non-diseased human and mouse brain tissues. METHODS: We systematically compared, based on large scale integrated microarray data, the transcriptomes of three anatomically distinct brain regions; prefrontal cortex (PFC), hippocampus (HIP) and striatum (STR), across human and mouse. The widely used DAVID web server was used to decipher the biological functions of the highly expressed genes that were identified using a previously reported approach. Venn analysis was used to depict the overlapping ratios of the notably enriched biological process (BP) terms (one tailed Fisher's exact test and Benjamini correction; adjusted p < 0.01) between two brain tissues. GOSemSim, an R package, was selected to perform GO semantic similarity analysis. Next, we adjusted signal intensities of orthologous genes by the total signals in all samples within species, and used one minus Pearson's correlation coefficient to assess the expression distance. Hierarchical clustering and principal component analysis (PCA) were selected for expression pattern analysis. Lineage specific expressed orthologous genes were identified by comparison of the most extreme sub-datasets across species and further verified using reverse transcription PCR (RT-PCR) and quantitative real-time PCR (qRT PCR). RESULTS: We found that the number of the significantly enriched BP terms of the highly expressed genes in human brain regions is larger than that in mouse corresponding brain regions. The mainly involved BP terms in human brain tissues associated with protein-membrane targeting and selenium metabolism are species specific. The overlapping ratios of all the significantly enriched BP terms between any two brain tissues across species are lower than that within species, but the pairwise semantic similarities are very high between any two brain tissues from either human or mouse. Hierarchical clustering analysis shows the biological functions of the highly expressed genes in brain tissues are more consistent within species than interspecies; whereas it shows the expression patterns of orthologous genes are evidently conserved between human and mouse equivalent brain tissues. In addition, we identified four orthologous genes (COX5B, WIF1, SLC4A10 and PLA2G7) that are species-specific, which have been widely studied and confirmed to be closely linked with neuro- physiological and pathological functions. CONCLUSION: Our study highlights the similarities and divergences in gene function and expression between human and mouse corresponding brain regions, including PFC, HIP and STR. PMID- 27716783 TI - Functional Properties of Mouse Chitotriosidase Expressed in the Periplasmic Space of Escherichia coli. AB - Chitotriosidase (Chit1) is an enzyme associated with various diseases, including Gaucher disease, chronic obstructive pulmonary disease, Alzheimer disease and cystic fibrosis. In this study, we first expressed mouse mature Chit1 fused with V5 and (His)6 tags at the C-terminus (Chit1-V5-His) in the cytoplasm of Escherichia coli and found that most of the expressed protein was insoluble. In contrast, Chit1 tagged with Protein A at the N-terminus and V5-His at the C terminus, was expressed in the periplasmic space of E. coli as a soluble protein and successfully purified. We evaluated the chitinolytic properties of the recombinant enzyme using 4-nitrophenyl N,N'-diacetyl-beta-D-chitobioside [4NP chitobioside, 4NP-(GlcNAc)2] and found that its activity was comparable to CHO cells-expressed Chit1-V5-His. Optimal conditions for the E. coli-produced Chit1 were pH ~5.0 at 50 degrees C. Chit1 was stable after 1 h incubation at pH 5.0~11.0 on ice and its chitinolytic activity was lost at pH 2.0, although the affinity to chitin remained unchanged. Chit1 efficiently cleaved crystalline and colloidal chitin substrates as well as oligomers of N-acetyl-D-glucosamine (GlcNAc) releasing primarily (GlcNAc)2 fragments at pH 5.0. On the other hand, (GlcNAc)3 was relatively resistant to digestion by Chit1. The degradation of 4NP (GlcNAc)2 and (GlcNAc)3 was less evident at pH 7.0~8.0, while (GlcNAc)2 production from colloidal chitin and (GlcNAc)6 at these pH conditions remained strong at the neutral conditions. Our results indicate that Chit1 degrades chitin substrates under physiological conditions and suggest its important pathophysiological roles in vivo. PMID- 27716784 TI - The Mechanism of Proinflammatory HDL Generation in Sickle Cell Disease Is Linked to Cell-Free Hemoglobin via Haptoglobin. AB - In sickle cell disease (SCD), the inflammatory properties of high-density lipoprotein (HDL) can be changed by cell-free hemoglobin (Hb), which is released into the blood during hemolysis. Hb in the plasma of SCD patients or mice can bind with HDL specifically inducing an inflammatory reaction. In our study, we found increased amounts of inflammatory factor proteins in the chronic oxidative state of SCD with higher levels of Hb, haptoglobin (Hp) and hemopexin (Hx) in the apolipoprotein A-I (ApoA-1) particles of HDL and the role of HDL is changed from being anti-inflammatory to proinflammatory. Our results also suggest Hp and Hx, the scavengers of Hb in HDL, are positively associated with inflammatory levels in SCD patients. HDL retained its inflammatory inhibition role in Hp-/- mice, with less Hb accumulation. Hx may further prevent inflammatory reaction because its level will be even higher when lack of Hx. We therefore demonstrated that Hp is indispensable during the process whereby Hb associates with HDL and plays a clear proinflammatory role. Therefore, it is essential to break the binding between Hb and Hp for treatment. The dissociation of Hb/Hp/Hx complexes may also play an important role in the study of other inflammatory angiogenesis-related diseases. PMID- 27716786 TI - Overlapping Leaves Covering Flowers in the Alpine Species Eriophyton wallichii (Lamiaceae): Key Driving Factors and Their Potential Impact on Pollination. AB - Extrafloral structures are supposed to have evolved to protect flowers from harsh physical environments but might have effects on pollination. Overlapping leaves cover flowers in Eriophyton wallichii, an alpine perennial endemic to the Himalaya-Hengduan Mountains. In previous study, it has showed that these extrafloral leaves can protect interior flowers from temperature fluctuations caused by drastic solar radiation fluctuations, but these leaves may also protect interior flowers from rain wash and UVB damage, and we do not know which one is the main function. In this study, we investigated whether rain and UVB protection are the main functions of overlapping leaves covering flowers and their potential impact on pollination. We first measured the intensities of UVB radiation in open air, beneath leaves and corollas, and then examined pollen susceptibility to different intensities of UVB and rain in the laboratory to estimate whether corollas per se protect interior pollen from UVB and rain damage. We also carried out pollination treatments and observed pollinator visitation of flowers with and without leaves in the field to assess whether the overlapping leaves covering flowers impair pollinator attraction. Our results showed that (1) water and strong UVB significantly decreased pollen germinability, but corollas per se could protect pollen from UVB and rain damage; (2) no autonomous self-pollination and apomixis occurred, and pollinators were essential for the reproduction of E. wallichii; however, flower coverage by overlapping leaves did not limit pollination. We suggested that rain and UVB protection was not the main function of overlapping leaves covered flowers, given that this protection can be provided by corollas per se. Alternatively, this extrafloral structure in E. wallichii may have evolved in response to extreme high temperatures associated with the strong solar radiation fluctuations. This indicates that, even in alpine plants, extreme high temperature may affect the evolution of plant extrafloral structures. PMID- 27716785 TI - Using Rich Data on Comorbidities in Case-Control Study Design with Electronic Health Record Data Improves Control of Confounding in the Detection of Adverse Drug Reactions. AB - Recent research has suggested that the case-control study design, unlike the self controlled study design, performs poorly in controlling confounding in the detection of adverse drug reactions (ADRs) from administrative claims and electronic health record (EHR) data, resulting in biased estimates of the causal effects of drugs on health outcomes of interest (HOI) and inaccurate confidence intervals. Here we show that using rich data on comorbidities and automatic variable selection strategies for selecting confounders can better control confounding within a case-control study design and provide a more solid basis for inference regarding the causal effects of drugs on HOIs. Four HOIs are examined: acute kidney injury, acute liver injury, acute myocardial infarction and gastrointestinal ulcer hospitalization. For each of these HOIs we use a previously published reference set of positive and negative control drugs to evaluate the performance of our methods. Our methods have AUCs that are often substantially higher than the AUCs of a baseline method that only uses demographic characteristics for confounding control. Our methods also give confidence intervals for causal effect parameters that cover the expected no effect value substantially more often than this baseline method. The case-control study design, unlike the self-controlled study design, can be used in the fairly typical setting of EHR databases without longitudinal information on patients. With our variable selection method, these databases can be more effectively used for the detection of ADRs. PMID- 27716787 TI - Fluoxetine Increases the Expression of miR-572 and miR-663a in Human Neuroblastoma Cell Lines. AB - Evidence suggests neuroprotective effects of fluoxetine, a selective serotonin reuptake inhibitor (SSRI), on the developed neurons in the adult brain. In contrast, the drug may be deleterious to immature or undifferentiated neural cells, although the mechanism is unclear. Recent investigations have suggested that microRNAs (miRNA) may be critical for effectiveness of psychotropic drugs including SSRI. We investigated whether fluoxetine could modulate expressions of neurologically relevant miRNAs in two neuroblastoma SK-N-SH and SH-SY5Y cell lines. Initial screening results revealed that three (miR-489, miR-572 and miR 663a) and four (miR-320a, miR-489, miR-572 and miR-663a) miRNAs were up-regulated in SK-N-SH cells and SH-SY5Y cells, respectively, after 24 hours treatment of fluoxetine (1-25 MUM). Cell viability was reduced according to the dose of fluoxetine. The upregulation of miR-572 and miR-663a was consistent in both the SH-SY5Y and SK-N-SH cells, confirmed by a larger scale culture condition. Our data is the first in vitro evidence that fluoxetine could increase the expression of miRNAs in undifferentiated neural cells, and that putative target genes of those miRNAs have been shown to be involved in fundamental neurodevelopmental processes. PMID- 27716788 TI - Vimar Is a Novel Regulator of Mitochondrial Fission through Miro. AB - As fundamental processes in mitochondrial dynamics, mitochondrial fusion, fission and transport are regulated by several core components, including Miro. As an atypical Rho-like small GTPase with high molecular mass, the exchange of GDP/GTP in Miro may require assistance from a guanine nucleotide exchange factor (GEF). However, the GEF for Miro has not been identified. While studying mitochondrial morphology in Drosophila, we incidentally observed that the loss of vimar, a gene encoding an atypical GEF, enhanced mitochondrial fission under normal physiological conditions. Because Vimar could co-immunoprecipitate with Miro in vitro, we speculated that Vimar might be the GEF of Miro. In support of this hypothesis, a loss-of-function (LOF) vimar mutant rescued mitochondrial enlargement induced by a gain-of-function (GOF) Miro transgene; whereas a GOF vimar transgene enhanced Miro function. In addition, vimar lost its effect under the expression of a constitutively GTP-bound or GDP-bound Miro mutant background. These results indicate a genetic dependence of vimar on Miro. Moreover, we found that mitochondrial fission played a functional role in high-calcium induced necrosis, and a LOF vimar mutant rescued the mitochondrial fission defect and cell death. This result can also be explained by vimar's function through Miro, because Miro's effect on mitochondrial morphology is altered upon binding with calcium. In addition, a PINK1 mutant, which induced mitochondrial enlargement and had been considered as a Drosophila model of Parkinson's disease (PD), caused fly muscle defects, and the loss of vimar could rescue these defects. Furthermore, we found that the mammalian homolog of Vimar, RAP1GDS1, played a similar role in regulating mitochondrial morphology, suggesting a functional conservation of this GEF member. The Miro/Vimar complex may be a promising drug target for diseases in which mitochondrial fission and fusion are dysfunctional. PMID- 27716789 TI - Risk of Adverse Obstetric and Neonatal Outcomes by Maternal Age: Quantifying Individual and Population Level Risk Using Routine UK Maternity Data. AB - OBJECTIVE: The objective of this study was to investigate whether moderately increased maternal age is associated with obstetric and neonatal outcome in a contemporary population, and to consider the possible role of co-morbidities in explaining any increased risk. STUDY DESIGN: Secondary analysis of routinely collected data from a large maternity unit in London, UK. Data were available on 51,225 singleton deliveries (>=22 weeks) occurring to women aged >=20 between 2004 and 2012. Modified Poisson regression was used to estimate risk ratios for the association between maternal age and obstetric and neonatal outcome (delivery type, postpartum haemorrhage, stillbirth, low birthweight, preterm birth, small for gestational age, neonatal unit admission), using the reference group 20-24 years. Population attributable fractions were calculated to quantify the population impact. RESULTS: We found an association between increasing maternal age and major postpartum haemorrhage (>=1000ml blood loss) (RR 1.36 95% CI 1.18 1.57 for age 25-29 rising to 2.41 95% CI 2.02-2.88 for age >=40). Similar trends were observed for caesarean delivery, most notably for elective caesareans (RR 1.64 95% CI 1.36-1.96 for age 25-29 rising to 4.94 95% CI 4.09-5.96 for age >=40). There was evidence that parity modified this association, with a higher prevalence of elective caesarean delivery in older nulliparous women. Women aged >=35 were at increased risk of low birthweight and preterm birth. We found no evidence that the risk of stillbirth, small for gestational age, or neonatal unit admission differed by maternal age. CONCLUSIONS: Our results suggest a gradual increase in the risk of caesarean delivery and postpartum haemorrhage from age 25, persisting after taking into account maternal BMI, hypertension and diabetes. The risk of low birthweight and preterm birth was elevated in women over 35. Further research is needed to understand the reasons behind the high prevalence of elective caesarean delivery in nulliparous older mothers. PMID- 27716790 TI - Cathepsin L Helps to Defend Mice from Infection with Influenza A. AB - Host-derived proteases can augment or help to clear infections. This dichotomy is exemplified by cathepsin L (CTSL), which helps Hendra virus and SARS coronavirus to invade cells, but is essential for survival in mice with mycoplasma pneumonia. The present study tested the hypothesis that CTSL protects mice from serious consequences of infection by the orthomyxovirus influenza A, which is thought to be activated by host-supplied proteases other than CTSL. Ctsl-/- mice infected with influenza A/Puerto Rico/8/34(H1N1) had larger lung viral loads and higher mortality than infected Ctsl+/+ mice. Lung inflammation in surviving infected mice peaked 14 days after initial infection, accompanied marked focal distal airway bronchiolization and epithelial metaplasia followed by desquamation and fibrotic interstitial remodeling, and persisted for at least 6 weeks. Most deaths occurred during the second week of infection in both groups of mice. In contrast to mycoplasma pneumonia, infiltrating cells were predominantly mononuclear rather than polymorphonuclear. The histopathology of lung inflammation and remodeling in survivors was similar in Ctsl-/- and Ctsl+/+ mice, although Ctsl+/+ mice cleared immunoreactive virus sooner. Furthermore, Ctsl-/- mice had profound deficits in CD4+ lymphocytes before and after infection and weaker production of pathogen specific IgG. Thus, CTSL appears to support innate as well as adaptive responses, which confer a survival advantage on mice infected with the orthomyxovirus influenza A. PMID- 27716791 TI - Molecular Mechanism of Silver Nanoparticles-Induced Human Osteoblast Cell Death: Protective Effect of Inducible Nitric Oxide Synthase Inhibitor. AB - BACKGROUND: Silver nanoparticles (AgNPs) show strong antibacterial properties, making them excellent candidates to be used in orthopaedic repair and regeneration. However, there are concerns regarding the cytotoxicity of AgNPs and molecular mechanisms underlying AgNPs-induced bone cells toxicity have not been elucidated. Therefore, the aim of our study was to explore mechanisms of AgNPs induced osteoblast cell death with particular emphasis on the role of nitric oxide (NO) generated by inducible nitric oxide synthase (iNOS). METHODS AND RESULT: Silver nanoparticles used in this study were 18.3+/-2.6 nm in size, uncoated, spherical, regular shape and their zeta potential was -29.1+/-2.4 mV as measured by transmission electron microscopy (TEM) and zetasizer. The release of silver (Ag) from AgNPs was measured in cell culture medium by atomic absorption spectroscopy (AAS). The exposure of human osteoblast cells (hFOB 1.19) to AgNPs at concentration of 30 or 60 MUg/mL for 24 or 48 hours, respectively resulted in cellular uptake of AgNPs and changes in cell ultrastructure. These changes were associated with apoptosis and necrosis as shown by flow cytometry and lactate dehydrogenase (LDH) assay as well as increased levels of pro-apoptotic Bax and decreased levels of anti-apoptotic Bcl-2 mRNA and protein. Importantly, we have found that AgNPs elevated the levels of nitric oxide (NO) with concomitant upregulation of inducible nitric oxide synthase (iNOS) mRNA and protein. A significant positive correlation was observed between the concentration of AgNPs and iNOS at protein and mRNA level (r = 0.837, r = 0.721, respectively; p<0.001). Finally, preincubation of osteoblast cells with N-iminoethyl-l-lysine (L-NIL), a selective iNOS inhibitor, as well as treating cells with iNOS small interfering RNAs (siRNA) significantly attenuated AgNPs-induced apoptosis and necrosis. Moreover, we have found that AgNPs-induced cells death is not related to Ag dissolution is cell culture medium. CONCLUSION: These results unambiguously demonstrate that increased expression of iNOS and generation of NO as well as NO derived reactive species is involved in AgNPs-induced osteoblast cell death. Our findings may help in development of new strategies to protect bone from AgNPs induced cytotoxicity and increase the safety of orthopaedic tissue repair. PMID- 27716792 TI - Lab-on-a-Chip-Based PCR-RFLP Assay for the Detection of Malayan Box Turtle (Cuora amboinensis) in the Food Chain and Traditional Chinese Medicines. AB - The Malayan box turtle (Cuora amboinensis) (MBT) is a vulnerable and protected turtle species, but it is a lucrative item in the illegal wildlife trade because of its great appeal as an exotic food item and in traditional medicine. Although several polymerase chain reaction (PCR) assays to identify MBT by various routes have been documented, their applicability for forensic authentication remains inconclusive due to the long length of the amplicon targets, which are easily broken down by natural decomposition, environmental stresses or physiochemical treatments during food processing. To address this research gap, we developed, for the first time, a species-specific PCR-restriction fragment length polymorphism (RFLP) assay with a very short target length (120 bp) to detect MBT in the food chain; this authentication ensured better security and reliability through molecular fingerprints. The PCR-amplified product was digested with Bfa1 endonuclease, and distinctive restriction fingerprints (72, 43 and 5 bp) for MBT were found upon separation in a microfluidic chip-based automated electrophoresis system, which enhances the resolution of short oligos. The chances of any false negative identifications were eliminated through the use of a universal endogenous control for eukaryotes, and the limit of detection was 0.0001 ng DNA or 0.01% of the meat under admixed states. Finally, the optimized PCR-RFLP assay was validated for the screening of raw and processed commercial meatballs, burgers and frankfurters, which are very popular in most countries. The optimized PCR-RFLP assay was further used to screen MBT materials in 153 traditional Chinese medicines of 17 different brands and 62 of them were found MBT positive; wherein the ingredients were not declared in product labels. Overall, the novel assay demonstrated sufficient merit for use in any forensic and/or archaeological authentication of MBT, even under a state of decomposition. PMID- 27716793 TI - Outcomes Definitions and Statistical Tests in Oncology Studies: A Systematic Review of the Reporting Consistency. AB - BACKGROUND: Quality of reporting for Randomized Clinical Trials (RCTs) in oncology was analyzed in several systematic reviews, but, in this setting, there is paucity of data for the outcomes definitions and consistency of reporting for statistical tests in RCTs and Observational Studies (OBS). The objective of this review was to describe those two reporting aspects, for OBS and RCTs in oncology. METHODS: From a list of 19 medical journals, three were retained for analysis, after a random selection: British Medical Journal (BMJ), Annals of Oncology (AoO) and British Journal of Cancer (BJC). All original articles published between March 2009 and March 2014 were screened. Only studies whose main outcome was accompanied by a corresponding statistical test were included in the analysis. Studies based on censored data were excluded. Primary outcome was to assess quality of reporting for description of primary outcome measure in RCTs and of variables of interest in OBS. A logistic regression was performed to identify covariates of studies potentially associated with concordance of tests between Methods and Results parts. RESULTS: 826 studies were included in the review, and 698 were OBS. Variables were described in Methods section for all OBS studies and primary endpoint was clearly detailed in Methods section for 109 RCTs (85.2%). 295 OBS (42.2%) and 43 RCTs (33.6%) had perfect agreement for reported statistical test between Methods and Results parts. In multivariable analysis, variable "number of included patients in study" was associated with test consistency: aOR (adjusted Odds Ratio) for third group compared to first group was equal to: aOR Grp3 = 0.52 [0.31-0.89] (P value = 0.009). CONCLUSION: Variables in OBS and primary endpoint in RCTs are reported and described with a high frequency. However, statistical tests consistency between methods and Results sections of OBS is not always noted. Therefore, we encourage authors and peer reviewers to verify consistency of statistical tests in oncology studies. PMID- 27716794 TI - A Case-Crossover Study of Heat Exposure and Injury Risk in Outdoor Agricultural Workers. AB - BACKGROUND: Recent research suggests that heat exposure may increase the risk of traumatic injuries. Published heat-related epidemiological studies have relied upon exposure data from individual weather stations. OBJECTIVE: To evaluate the association between heat exposure and traumatic injuries in outdoor agricultural workers exposed to ambient heat and internal heat generated by physical activity using modeled ambient exposure data. METHODS: A case-crossover study using time stratified referent selection among 12,213 outdoor agricultural workers with new Washington State Fund workers' compensation traumatic injury claims between 2000 and 2012 was conducted. Maximum daily Humidex exposures, derived from modeled meteorological data, were assigned to latitudes and longitudes of injury locations on injury and referent dates. Conditional logistic regression was used to estimate odds ratios of injury for a priori daily maximum Humidex categories. RESULTS: The mean of within-stratum (injury day and corresponding referent days) standard deviations of daily maximum Humidex was 4.8. The traumatic injury odds ratio was 1.14 (95% confidence interval 1.06, 1.22), 1.15 (95% confidence interval 1.06, 1.25), and 1.10 (95% confidence interval 1.01, 1.20) for daily maximum Humidex of 25-29, 30-33, and >=34, respectively, compared to < 25, adjusted for self-reported duration of employment. Stronger associations were observed during cherry harvest duties in the June and July time period, compared to all duties over the entire study period. CONCLUSIONS: Agricultural workers laboring in warm conditions are at risk for heat-related traumatic injuries. Combined heat-related illness and injury prevention efforts should be considered in high-risk populations exposed to warm ambient conditions in the setting of physical exertion.

AB - Heavy glycosylation of the envelope (Env) surface subunit, gp120, is a key adaptation of HIV-1; however, the precise effects of glycosylation on the folding, conformation and dynamics of this protein are poorly understood. Here we explore the patterns of HIV-1 Env gp120 glycosylation, and particularly the enrichment in glycosylation sites proximal to the disulfide linkages at the base of the surface-exposed variable domains. To dissect the influence of glycans on the conformation these regions, we focused on an antigenic peptide fragment from a disulfide bridge-bounded region spanning the V1 and V2 hyper-variable domains of HIV-1 gp120. We used replica exchange molecular dynamics (MD) simulations to investigate how glycosylation influences its conformation and stability. Simulations were performed with and without N-linked glycosylation at two sites that are highly conserved across HIV-1 isolates (N156 and N160); both are contacts for recognition by V1V2-targeted broadly neutralizing antibodies against HIV-1. Glycosylation stabilized the pre-existing conformations of this peptide construct, reduced its propensity to adopt other secondary structures, and provided resistance against thermal unfolding. Simulations performed in the context of the Env trimer also indicated that glycosylation reduces flexibility of the V1V2 region, and provided insight into glycan-glycan interactions in this region. These stabilizing effects were influenced by a combination of factors, including the presence of a disulfide bond between the Cysteines at 131 and 157, which increased the formation of beta-strands. Together, these results provide a mechanism for conservation of disulfide linkage proximal glycosylation adjacent to the variable domains of gp120 and begin to explain how this could be exploited to enhance the immunogenicity of those regions. These studies suggest that glycopeptide immunogens can be designed to stabilize the most relevant Env conformations to focus the immune response on key neutralizing epitopes.

AB - A cohort study was undertaken to analyze the risk of recurrence among 1616 patients with primary squamous cell carcinoma of the larynx from 1983 to 2010 at a single, tertiary academic center in Oslo, Norway. The cohort was followed from the date of diagnosis to September 2011. Competing risk regression analysis assessed the association between various risk factors and the risk of recurrence, where death was considered a competing event. Recurrence was observed in 368 patients (23%) during the study period. The majority (71%) of recurrences involved the location of the primary tumor. The overall risk of recurrence during the first three years after initiating treatment was 20.5%. Increased risk of recurrence was observed in patients with supraglottic cancer, younger patients, those with T2-T3 tumors and in patients treated in the earlier part of the study period. Significant factors for recurrence in glottic carcinomas were age, treatment in the earlier part of the study and T-status, whereas age was a significant factor in supraglottic cancer. N-status appeared less significant. In conclusion, follow-up of laryngeal squamous cell carcinoma should place particular emphasis on the site of the primary tumor, younger patients, cases of supraglottic cancer and T2-T4 primary tumors, especially during the first three years after treatment. More studies are needed to assess the impact of surgical versus non-surgical treatment, and eventually the significance of recurrence, for disease-specific and overall survival in cases of advanced laryngeal squamous cell carcinoma. PMID- 27716796 TI - Functional Trade-Offs in Promiscuous Enzymes Cannot Be Explained by Intrinsic Mutational Robustness of the Native Activity. AB - The extent to which an emerging new function trades off with the original function is a key characteristic of the dynamics of enzyme evolution. Various cases of laboratory evolution have unveiled a characteristic trend; a large increase in a new, promiscuous activity is often accompanied by only a mild reduction of the native, original activity. A model that associates weak trade offs with "evolvability" was put forward, which proposed that enzymes possess mutational robustness in the native activity and plasticity in promiscuous activities. This would enable the acquisition of a new function without compromising the original one, reducing the benefit of early gene duplication and therefore the selection pressure thereon. Yet, to date, no experimental study has examined this hypothesis directly. Here, we investigate the causes of weak trade offs by systematically characterizing adaptive mutations that occurred in two cases of evolutionary transitions in enzyme function: (1) from phosphotriesterase to arylesterase, and (2) from atrazine chlorohydrolase to melamine deaminase. Mutational analyses in various genetic backgrounds revealed that, in contrast to the prevailing model, the native activity is less robust to mutations than the promiscuous activity. For example, in phosphotriesterase, the deleterious effect of individual mutations on the native phosphotriesterase activity is much larger than their positive effect on the promiscuous arylesterase activity. Our observations suggest a revision of the established model: weak trade-offs are not caused by an intrinsic robustness of the native activity and plasticity of the promiscuous activity. We propose that upon strong adaptive pressure for the new activity without selection against the original one, selected mutations will lead to the largest possible increases in the new function, but whether and to what extent they decrease the old function is irrelevant, creating a bias towards initially weak trade-offs and the emergence of generalist enzymes. PMID- 27716798 TI - MicroNeurotrophins Improve Survival in Motor Neuron-Astrocyte Co-Cultures but Do Not Improve Disease Phenotypes in a Mutant SOD1 Mouse Model of Amyotrophic Lateral Sclerosis. AB - Amyotrophic Lateral Sclerosis (ALS) is a neurodegenerative disease caused by loss of motor neurons. ALS patients experience rapid deterioration in muscle function with an average lifespan of 3-5 years after diagnosis. Currently, the most effective therapeutic only extends lifespan by a few months, thus highlighting the need for new and improved therapies. Neurotrophic factors (NTFs) are important for neuronal development, maintenance, and survival. NTF treatment has previously shown efficacy in pre-clinical ALS models. However, clinical trials using NTFs produced no major improvements in ALS patients, due in part to the limited blood brain barrier (BBB) penetration. In this study we assessed the potential neuroprotective effects of a novel class of compounds known as MicroNeurotrophins (MNTs). MNTs are derivatives of Dehydroepiandrosterone (DHEA), an endogenous neurosteroid that can cross the BBB and bind to tyrosine kinase receptors mimicking the pro-survival effects of NTFs. Here we sought to determine whether MNTs were neuroprotective in two different models of ALS. Our results demonstrate that BNN27 (10 MUM) attenuated loss of motor neurons co-cultured with astrocytes derived from human ALS patients with SOD1 mutations via the reduction of oxidative stress. Additionally, in the G93A SOD1 mouse, BNN27 (10 mg/kg) treatment attenuated motor behavioral impairment in the paw grip endurance and rotarod tasks at postnatal day 95 in female but not male mice. In contrast, BNN27 (10 mg/kg and 50 mg/kg) treatment did not alter any other behavioral outcome or neuropathological marker in male or female mice. Lastly, BNN27 was not detected in post-mortem brain or spinal cord tissue of treated mice due to the rapid metabolism of BNN27 by mouse hepatocytes relative to human hepatocytes. Together, these findings demonstrate that BNN27 treatment failed to yield significant neuroprotective effects in the G93A SOD1 model likely due to its rapid rate of metabolism in mice. PMID- 27716800 TI - Re-Evaluation of Phylogenetic Relationships among Species of the Mangrove Genus Avicennia from Indo-West Pacific Based on Multilocus Analyses. AB - Avicennia L. (Avicenniaceae), one of the most diverse mangrove genera, is distributed widely in tropical and subtropical intertidal zones worldwide. Five species of Avicennia in the Indo-West Pacific region have been previously described. However, their phylogenetic relationships were determined based on morphological and allozyme data. To enhance our understanding of evolutionary patterns in the clade, we carried out a molecular phylogenetic study using wide sampling and multiple loci. Our results support two monophyletic clades across all species worldwide in Avicennia: an Atlantic-East Pacific (AEP) lineage and an Indo-West Pacific (IWP) lineage. This split is in line with biogeographic distribution of the clade. Focusing on the IWP branch, we reconstructed a detailed phylogenetic tree based on sequences from 25 nuclear genes. The results identified three distinct subclades, (1) A. rumphiana and A. alba, (2) A. officinalis and A. integra, and (3) the A. marina complex, with high bootstrap support. The results strongly corresponded to two morphological traits in floral structure: stigma position in relation to the anthers and style length. Using Bayesian dating methods we estimated diversification of the IWP lineage was dated to late Miocene (c. 6.0 million years ago) and may have been driven largely by the fluctuating sea levels since that time. PMID- 27716799 TI - Rapid and Objective Assessment of Neural Function in Autism Spectrum Disorder Using Transient Visual Evoked Potentials. AB - OBJECTIVE: There is a critical need to identify biomarkers and objective outcome measures that can be used to understand underlying neural mechanisms in autism spectrum disorder (ASD). Visual evoked potentials (VEPs) offer a noninvasive technique to evaluate the functional integrity of neural mechanisms, specifically visual pathways, while probing for disease pathophysiology. METHODS: Transient VEPs (tVEPs) were obtained from 96 unmedicated children, including 37 children with ASD, 36 typically developing (TD) children, and 23 unaffected siblings (SIBS). A conventional contrast-reversing checkerboard condition was compared to a novel short-duration condition, which was developed to enable objective data collection from severely affected populations who are often excluded from electroencephalographic (EEG) studies. RESULTS: Children with ASD showed significantly smaller amplitudes compared to TD children at two of the earliest critical VEP components, P60-N75 and N75-P100. SIBS showed intermediate responses relative to ASD and TD groups. There were no group differences in response latency. Frequency band analyses indicated significantly weaker responses for the ASD group in bands encompassing gamma-wave activity. Ninety-two percent of children with ASD were able to complete the short-duration condition compared to 68% for the standard condition. CONCLUSIONS: The current study establishes the utility of a short-duration tVEP test for use in children at varying levels of functioning and describes neural abnormalities in children with idiopathic ASD. Implications for excitatory/inhibitory balance as well as the potential application of VEP for use in clinical trials are discussed. PMID- 27716801 TI - Sympathy Crying: Insights from Infrared Thermal Imaging on a Female Sample. AB - Sympathy crying is an odd and complex mixture of physiological and emotional phenomena. Standard psychophysiological theories of emotion cannot attribute crying to a single subdivision of the autonomic nervous system (ANS) and disagreement exists regarding the emotional origin of sympathy crying. The current experiment examines sympathy crying using functional thermal infrared imaging (FTII), a novel contactless measure of ANS activity. To induce crying female participants were given the choice to decide which film they wanted to cry to. Compared to baseline, temperature started increasing on the forehead, the peri-orbital region, the cheeks and the chin before crying and reached even higher temperatures during crying. The maxillary area showed the opposite pattern and a gradual temperature decrease was observed compared to baseline as a result of emotional sweating. The results suggest that tears of sympathy are part of a complex autonomic interaction between the sympathetic and the parasympathetic nervous systems, with the latter preceding the former. The emotional origin of the phenomenon seems to derive from subjective internal factors that relate to one's personal experiences and attributes with tears arising in the form of catharses or as part of shared sadness. PMID- 27716803 TI - Major Shift of Toxigenic V. cholerae O1 from Ogawa to Inaba Serotype Isolated from Clinical and Environmental Samples in Haiti. AB - In October of 2010, an outbreak of cholera was confirmed in Haiti for the first time in more than a century. A single clone of toxigenic Vibrio cholerae O1 biotype El Tor serotype Ogawa strain was implicated as the cause. Five years after the onset of cholera, in October, 2015, we have discovered a major switch (ranging from 7 to 100%) from Ogawa serotype to Inaba serotype. Furthermore, using wbeT gene sequencing and comparative sequence analysis, we now demonstrate that, among 2013 and 2015 Inaba isolates, the wbeT gene, responsible for switching Ogawa to Inaba serotype, sustained a unique nucleotide mutation not found in isolates obtained from Haiti in 2012. Moreover, we show that, environmental Inaba isolates collected in 2015 have the identical mutations found in the 2015 clinical isolates. Our data indicate that toxigenic V. cholerae O1 serotype Ogawa can rapidly change its serotype to Inaba, and has the potential to cause disease in individuals who have acquired immunity against Ogawa serotype. Our findings highlight the importance of monitoring of toxigenic V. cholerae O1 and cholera in countries with established endemic disease. PMID- 27716802 TI - Transcriptome Analysis of Gene Expression during Chinese Water Chestnut Storage Organ Formation. AB - The product organ (storage organ; corm) of the Chinese water chestnut has become a very popular food in Asian countries because of its unique nutritional value. Corm formation is a complex biological process, and extensive whole genome analysis of transcripts during corm development has not been carried out. In this study, four corm libraries at different developmental stages were constructed, and gene expression was identified using a high-throughput tag sequencing technique. Approximately 4.9 million tags were sequenced, and 4,371,386, 4,372,602, 4,782,494, and 5,276,540 clean tags, including 119,676, 110,701, 100,089, and 101,239 distinct tags, respectively, were obtained after removal of low-quality tags from each library. More than 39% of the distinct tags were unambiguous and could be mapped to reference genes, while 40% were unambiguous tag-mapped genes. After mapping their functions in existing databases, a total of 11,592, 10,949, 10,585, and 7,111 genes were annotated from the B1, B2, B3, and B4 libraries, respectively. Analysis of the differentially expressed genes (DEGs) in B1/B2, B2/B3, and B3/B4 libraries showed that most of the DEGs at the B1/B2 stages were involved in carbohydrate and hormone metabolism, while the majority of DEGs were involved in energy metabolism and carbohydrate metabolism at the B2/B3 and B3/B4 stages. All of the upregulated transcription factors and 9 important genes related to product organ formation in the above four stages were also identified. The expression changes of nine of the identified DEGs were validated using a quantitative PCR approach. This study provides a comprehensive understanding of gene expression during corm formation in the Chinese water chestnut. PMID- 27716805 TI - How Metabolic Diseases Impact the Use of Antimicrobials: A Formal Demonstration in the Field of Veterinary Medicine. AB - Decreasing the use of antimicrobials has become a primary objective for both human and veterinary medicine in many countries. Medical prevention and good nutrition are seen as key parameters for reducing antimicrobial use. However, little consideration has been given to how metabolic diseases may influence the use of antimicrobials in humans and animals through limiting the prevalence and severity of infectious diseases. To quantify this relationship using the example of a common metabolic disease in dairy cows (subclinical ketosis, SCK), we constructed a stochastic model reporting the total quantity of curative antimicrobials for a given population with the prevalence of cows at risk for SCK. We considered the prevalence of SCK, the relative risk of the disease in cases of SCK compared to no SCK and the use of antimicrobials to treat SCK induced infectious diseases. Reducing the percentage of cows at risk for SCK from 80% to 10% was associated with an average decrease in the use of antimicrobials of 11% (prevalence of SCK from 34% to 17%, respectively) or 25% (prevalence of SCK from 68% to 22%, respectively), depending on the relative risk to contract SCK if risk was present. For a large percentage of the cows at risk for SCK, using a preventive bolus of monensin reduced the use of curative antimicrobials to the same level that was observed when the percentage of cows at risk for SCK was low. The present work suggests similar approaches for obesity and diabetes. PMID- 27716804 TI - The Sero-epidemiology of Coxiella burnetii in Humans and Cattle, Western Kenya: Evidence from a Cross-Sectional Study. AB - Evidence suggests that the intracellular bacterial pathogen Coxiella burnetii (which causes Q fever) is widespread, with a near global distribution. While there has been increasing attention to Q fever epidemiology in high-income settings, a recent systematic review highlighted significant gaps in our understanding of the prevalence, spatial distribution and risk factors for Q fever infection across Africa. This research aimed to provide a One Health assessment of Q fever epidemiology in parts of Western and Nyanza Provinces, Western Kenya, in cattle and humans. A cross-sectional survey was conducted: serum samples from 2049 humans and 955 cattle in 416 homesteads were analysed for C. burnetii antibodies. Questionnaires covering demographic, socio-economic and husbandry information were also administered. These data were linked to environmental datasets based on geographical locations (e.g., land cover). Correlation and spatial-cross correlation analyses were applied to assess the potential link between cattle and human seroprevalence. Multilevel regression analysis was used to assess the relationships between a range of socio-economic, demographic and environmental factors and sero-positivity in both humans and animals. The overall sero-prevalence of C. burnetii was 2.5% in humans and 10.5% in cattle, but we found no evidence of correlation between cattle and human seroprevalence either within households, or when incorporating spatial proximity to other households in the survey. Multilevel modelling indicated the importance of several factors for exposure to the organism. Cattle obtained from market (as opposed to those bred in their homestead) and those residing in areas with lower precipitation levels had the highest sero-prevalence. For humans, the youngest age group had the highest odds of seropositivity, variations were observed between ethnic groups, and frequent livestock contact (specifically grazing and dealing with abortion material) was also a risk factor. These results illustrate endemicity of C. burnetii in western Kenya, although prevalence is relatively low. The analysis indicates that while environmental factors may play a role in cattle exposure patterns, human exposure patterns are likely to be driven more strongly by livestock contacts. The implication of livestock markets in cattle exposure risks suggests these may be a suitable target for interventions. PMID- 27716806 TI - Evidence of In Vivo Absorption of Lactate and Modulation of Short Chain Fatty Acid Absorption from the Reticulorumen of Non-Lactating Cattle Fed High Concentrate Diets. AB - Short-chain fatty acids (SCFAs) and lactate are endproducts of rumen fermentation and important energy sources for the host ruminant. Because their rapid accumulation results in ruminal acidosis, enhancement of the absorption of SCFA and lactate across reticuloruminal wall is instrumental in increasing energy supply and preventing ruminal acidosis in cattle. This study investigated whether the reticuloruminal absorption of SCFAs and lactate was altered by different strategies of high concentrate feeding. Eight rumen-cannulated, non-lactating Holstein cows were fed a forage-only diet (baseline) and then gradually adapted over 6 d to a 60% concentrate level. Thereafter, this concentrate-rich diet was fed for 4 wk either continuously (Con; n = 8) or interruptedly (Int; n = 8). Absorption of SCFAs and lactate was determined in vivo from the experimental buffer introduced into the washed reticulorumen. The buffer contained acetate, propionate, butyrate and lactate at a concentration of 60, 30, 10 and 5 mmol/L, respectively and Cr-EDTA as a marker for correcting ruminal water fluxes. The reticuloruminal absorption after 35 and 65 min of buffer incubation was measured at the baseline, after 1 wk of 60% concentrate feeding in the interrupted model (Int-1) and after 4 wk of concentrate feeding in both feeding models (Int-4 and Con-4). Data showed that the absorption rates of individual and total SCFAs during the first 35 min of incubation of Con-4 were highest (~1.7 times compared to baseline), while Int-1 and Int-4 were similar to respective baseline. Lactate was not absorbed during forage-only baseline and 1-wk concentrate feeding, but after 4-wk feeding of concentrates in both models. In conclusion, SCFAs absorption across the reticulorumen of non-lactating cattle was enhanced by the 4 wk continuous concentrate feeding, which seems to be more advantageous in terms of rumen acidosis prevention compared to the interrupted feeding model. The study provides evidence of lactate absorption across the reticulorumen of non-lactating cattle after both continuous and interrupted 4-wk concentrate feeding. PMID- 27716807 TI - Local Transcriptional Control of YUCCA Regulates Auxin Promoted Root-Growth Inhibition in Response to Aluminium Stress in Arabidopsis. AB - Auxin is necessary for the inhibition of root growth induced by aluminium (Al) stress, however the molecular mechanism controlling this is largely unknown. Here, we report that YUCCA (YUC), which encodes flavin monooxygenase-like proteins, regulates local auxin biosynthesis in the root apex transition zone (TZ) in response to Al stress. Al stress up-regulates YUC3/5/7/8/9 in the root apex TZ, which we show results in the accumulation of auxin in the root-apex TZ and root-growth inhibition during the Al stress response. These Al-dependent changes in the regulation of YUCs in the root-apex TZ and YUC-regulated root growth inhibition are dependent on ethylene signalling. Increasing or disruption of ethylene signalling caused either enhanced or reduced up-regulation, respectively, of YUCs in root-apex TZ in response to Al stress. In addition, ethylene enhanced root growth inhibition under Al stress was strongly alleviated in yuc mutants or by co-treatment with yucasin, an inhibitor of YUC activity, suggesting a downstream role of YUCs in this process. Moreover, ethylene insensitive 3 (EIN3) is involved into the direct regulation of YUC9 transcription in this process. Furthermore, we demonstrated that PHYTOCHROME INTERACTING FACTOR4 (PIF4) functions as a transcriptional activator for YUC5/8/9. PIF4 promotes Al-inhibited primary root growth by regulating the local expression of YUCs and auxin signal in the root-apex TZ. The Al-induced expression of PIF4 in root TZ acts downstream of ethylene signalling. Taken together, our results highlight a regulatory cascade for YUCs-regulated local auxin biosynthesis in the root-apex TZ mediating root growth inhibition in response to Al stress. PMID- 27716808 TI - Bovine Lhx8, a Germ Cell-Specific Nuclear Factor, Interacts with Figla. AB - LIM homeobox 8 (Lhx8) is a germ cell-specific transcription factor essential for the development of oocytes during early oogenesis. In mice, Lhx8 deficiency causes postnatal oocyte loss and affects the expression of many oocyte-specific genes. The aims of this study were to characterize the bovine Lhx8 gene, determine its mRNA expression during oocyte development and early embryogenesis, and evaluate its interactions with other oocyte-specific transcription factors. The bovine Lhx8 gene encodes a protein of 377 amino acids. A splice variant of Lhx8 (Lhx8_v1) was also identified. The predicted bovine Lhx8 protein contains two LIM domains and one homeobox domain. However, one of the LIM domains in Lhx8_v1 is incomplete due to deletion of 83 amino acids near the N terminus. Both Lhx8 and Lhx8_v1 transcripts were only detected in the gonads but none of the somatic tissues examined. The expression of Lhx8 and Lhx8_v1 appears to be restricted to oocytes as none of the transcripts was detectable in granulosa or theca cells. The maternal Lhx8 transcript is abundant in GV and MII stage oocytes as well as in early embryos but disappear by morula stage. A nuclear localization signal that is required for the import of Lhx8 into nucleus was identified, and Lhx8 is predominantly localized in the nucleus when ectopically expressed in mammalian cells. Finally, a novel interaction between Lhx8 and Figla, another transcription factor essential for oogenesis, was detected. The results provide new information for studying the mechanisms of action for Lhx8 in oocyte development and early embryogenesis. PMID- 27716809 TI - A High-Throughput Small Molecule Screen for C. elegans Linker Cell Death Inhibitors. AB - Programmed cell death is a ubiquitous process in metazoan development. Apoptosis, one cell death form, has been studied extensively. However, mutations inactivating key mammalian apoptosis regulators do not block most developmental cell culling, suggesting that other cell death pathways are likely important. Recent work in the nematode Caenorhabditis elegans identified a non-apoptotic cell death form mediating the demise of the male-specific linker cell. This cell death process (LCD, linker cell-type death) is morphologically conserved, and its molecular effectors also mediate axon degeneration in mammals and Drosophila. To develop reagents to manipulate LCD, we established a simple high-throughput screening protocol for interrogating the effects of small molecules on C. elegans linker cell death in vivo. From 23,797 compounds assayed, 11 reproducibly block linker cell death onset. Of these, five induce animal lethality, and six promote a reversible developmental delay. These results provide proof-of principle validation of our screening protocol, demonstrate that developmental progression is required for linker cell death, and suggest that larger scale screens may identify LCD-specific small-molecule regulators that target the LCD execution machinery. PMID- 27716810 TI - Associations of Serum Levels of Sex Hormones in Follicular and Luteal Phases of the Menstrual Cycle with Breast Tissue Characteristics in Young Women. AB - BACKGROUND: In previous work in young women aged 15-30 years we measured breast water and fat using MR and obtained blood for hormone assays on the same day in the follicular phase of the menstrual cycle. Only serum growth hormone levels and sex hormone binding globulin (SHBG) were significantly associated with percent breast water after adjustment for covariates. The sex hormones estradiol, progesterone and testosterone were not associated with percent water in the breast in the follicular phase of the menstrual cycle. In the present study we have examined the association of percent breast water with serum levels of sex hormones in both follicular and luteal phase of the menstrual cycle. METHODS: In 315 healthy white Caucasian young women aged 15-30 with regular menstrual cycles who had not used oral contraceptives or other hormones in the previous 6 months, we used MR to determine percent breast water, and obtained blood samples for hormone assays within 10 days of the onset of the most recent menstrual cycle (follicular phase) of the cycle on the same day as the MR scan, and a second blood sample on days 19-24 of the cycle. Serum progesterone levels of > = 5 mmol/L in days 19-24 were used to define the 225 subjects with ovulatory menstrual cycles, whose data are the subject of the analyses shown here. RESULTS: SHBG was positively associated with percent water in both follicular and luteal phases of the menstrual cycle. Total and free estradiol and total and free testosterone were not associated with percent water in the follicular phase, but in young women with ovulatory cycles, were all negatively associated with percent water in the luteal phase. CONCLUSIONS: Our results from young women aged 15-30 years add to the evidence that the extent of fibroglandular tissue in the breast that is reflected in both mammographic density and breast water is associated positively with higher serum levels of SHBG, but not with higher levels of sex hormones. PMID- 27716811 TI - Risk Factors and Clinical Outcomes in Preterm Infants with Pulmonary Hypertension. AB - BACKGROUND: Pulmonary hypertension (PH) is a significant cause of morbidity in preterm infants, but no screening guidelines exist. We sought to identify risk factors and clinical outcomes associated with PH in preterm infants to develop a PH risk score. METHODS: Retrospective analysis of two separate populations of preterm infants (NICU cohort n = 230; Clinic registry n = 580). RESULTS: 8.3% of the NICU cohort had PH after 4 weeks of age, while 14.8% of the clinic registry had PH after 2 months of age. Lower birth weights and longer initial hospitalizations were associated with PH in both populations (p<0.001 for all tests). Using adjusted logistic regression, patent ductus arteriosus (PDA) requiring ligation was associated with PH in both the NICU cohort (OR: 3.19; p = 0.024) and the clinic registry (OR: 2.67; p<0.001). Risk factors (birth weight <=780 grams, home supplemental oxygen use, and PDA ligation) identified in the clinic registry (training dataset) were validated in the NICU cohort with 0-1 factors present were associated with <=1.5% probability of having PH, any 2 factors with a 25% probability, and all 3 factors with a 40% probability. CONCLUSIONS: Lower birth weight, PDA ligation, and respiratory support were associated with PH in both populations. A PH risk score based on clinical indicators from the training dataset predicted PH in the validation set. This risk score could help focus resources to preterm infants at higher risk for PH. Further work is needed to determine whether earlier or more aggressive management of ductal lesions could alter PH outcomes. PMID- 27716812 TI - Use of Warning Signs for Dengue by Pediatric Health Care Staff in Brazil. AB - OBJECTIVE: The aim of this study was to describe the use of dengue warning signs by pediatric healthcare staff in the Brazilian public health care system. METHODS: Cross-sectional study (2012) with physicians, nurses, and nurse technicians assisting children in five health care facilities. Participants reported the use and importance of dengue warning signs in pediatrics clinical practice through a structured questionnaire. Differences in the use of signs (chi square test) and in the ranking assigned to each of them (Kruskal-Wallis) were assessed according to health care occupation and level of care (p<0.05). RESULTS: The final sample comprised 474 participants (97%), mean age of 37 years (standard deviation = 10.3), mainly females (83.8%), physicians (40.1%) and from tertiary care (75.1%). The majority (91%) reported using warning signs for dengue in pediatrics clinical practice. The most widely used and highly valued signs were major hemorrhages (gastrointestinal, urinary), abdominal pain, and increase in hematocrit concurrent or not with rapid decrease in platelet count. Persistent vomiting as well as other signs of plasma leakage such as respiratory distress and lethargy/restlessness were not identified as having the same degree of importance, especially by nurse technicians and in primary or secondary care. DISCUSSION: Although most health care staff reported using dengue warning signs, it would be useful to extend the training for identifying easily recognizable signs of plasma leakage that occur regardless of bleeding. PMID- 27716813 TI - Human Resources for Treating HIV/AIDS: Are the Preventive Effects of Antiretroviral Treatment a Game Changer? AB - Shortages of human resources for treating HIV/AIDS (HRHA) are a fundamental barrier to reaching universal antiretroviral treatment (ART) coverage in developing countries. Previous studies suggest that recruiting HRHA to attain universal ART coverage poses an insurmountable challenge as ART significantly increases survival among HIV-infected individuals. While new evidence about ART's prevention benefits suggests fewer infections may mitigate the challenge, new policies such as treatment-as-prevention (TasP) will exacerbate it. We develop a mathematical model to analytically study the net effects of these countervailing factors. Using South Africa as a case study, we find that contrary to previous results, universal ART coverage is achievable even with current HRHA numbers. However, larger health gains are possible through a surge-capacity policy that aggressively recruits HRHA to reach universal ART coverage quickly. Without such a policy, TasP roll-out can increase health losses by crowding out sicker patients from treatment, unless a surge capacity exclusively for TasP is also created. PMID- 27716815 TI - Bounded Confidence under Preferential Flip: A Coupled Dynamics of Structural Balance and Opinions. AB - In this work we study the coupled dynamics of social balance and opinion formation. We propose a model where agents form opinions under bounded confidence, but only considering the opinions of their friends. The signs of social ties -friendships and enmities- evolve seeking for social balance, taking into account how similar agents' opinions are. We consider both the case where opinions have one and two dimensions. We find that our dynamics produces the segregation of agents into two cliques, with the opinions of agents in one clique differing from those in the other. Depending on the level of bounded confidence, the dynamics can produce either consensus of opinions within each clique or the coexistence of several opinion clusters in a clique. For the uni-dimensional case, the opinions in one clique are all below the opinions in the other clique, hence defining a "left clique" and a "right clique". In the two-dimensional case, our numerical results suggest that the two cliques are separated by a hyperplane in the opinion space. We also show that the phenomenon of unidimensional opinions identified by DeMarzo, Vayanos and Zwiebel (Q J Econ 2003) extends partially to our dynamics. Finally, in the context of politics, we comment about the possible relation of our results to the fragmentation of an ideology and the emergence of new political parties. PMID- 27716816 TI - Monetary Expansion and the Banking Lending Channel. AB - This paper examines the bank lending channel, which considers how monetary authority actions affect the variation of loans. We focus on the BRICS (Brazil, Russia, India, China and South Africa) totalizing 1254 banks from five countries in the period 2000-2012 (totalizing 13 years). The empirical results show that the effect of money supply growth on the growth of loans is non-linear and inverted U-shaped. In this context, our results show empirical evidence expansionary monetary policies do not increase the propensity of economic agents to systematically take greater risks on the market. After a certain level of money stock, increases in the money supply do not lead to increased negotiated credit.

AB - INTRODUCTION: Sensory peripheral neuropathy caused by paclitaxel is a common and dose limiting toxicity, for which there are currently no validated predictive biomarkers. We investigated the relationship between the Charcot-Marie-Tooth protein NDRG1 and paclitaxel-induced neuropathy. METHODS/MATERIALS: Archived mammary tissue specimen blocks of breast cancer patients who received weekly paclitaxel in a single centre were retrieved and NDRG1 immunohistochemistry was performed on normal nerve tissue found within the sample. The mean nerve NDRG1 score was defined by an algorithm based on intensity of staining and percentage of stained nerve bundles. NDRG1 scores were correlated with paclitaxel induced neuropathy. RESULTS: 111 patients were studied. 17 of 111 (15%) developed severe paclitaxel-induced neuropathy. The mean nerve NDRG1 expression score was 5.4 in patients with severe neuropathy versus 7.7 in those without severe neuropathy (p = 0.0019). A Receiver operating characteristic (ROC) curve analysis of the mean nerve NDRG1 score revealed an area under the curve of 0.74 (p = 0.0013) for the identification of severe neuropathy, with a score of 7 being most discriminative. 13/54 (24%) subjects with an NDRG1 score < = 7 developed severe neuropathy, compared to only 4/57 (7%) in those with a score >7 (p = 0.017). CONCLUSION: Low NDRG1 expression in nerve tissue present within samples of surgical resection may identify subjects at risk for severe paclitaxel-induced neuropathy. Since nerve biopsies are not routinely feasible for patients undergoing chemotherapy for early breast cancer, this promising biomarker strategy is compatible with current clinical workflow.

AB - In mammals, episodic memory and spatial cognition involve context-specific recruitment of unique ensembles in the hippocampal formation (HF). Despite their capacity for sophisticated spatial (e.g., for migration) and episodic-like (e.g., for food-caching) memory, the mechanisms underlying contextual representation in birds is not well understood. Here we demonstrate environment-specific Egr1 expression as male brown-headed cowbirds (Molothrus ater) navigate environments for food reward, showing that the avian HF, like its mammalian counterpart, recruits distinct neuronal ensembles to represent different contexts. PMID- 27716818 TI - Impact of Age and Sex on CD4+ Cell Count Trajectories following Treatment Initiation: An Analysis of the Tanzanian HIV Treatment Database. AB - OBJECTIVE: New guidelines recommend that all HIV-infected individuals initiate antiretroviral treatment (ART) immediately following diagnosis. This study describes how immune reconstitution varies by gender and age to help identify poorly reconstituting subgroups and inform targeted testing initiatives. DESIGN: Longitudinal data from the outpatient monitoring system of the National AIDS Control Program in Tanzania. METHODS: An asymptotic nonlinear mixed effects model was fit to post-treatment CD4+ cell count trajectories, allowing for fixed effects of age and sex, and an age by sex interaction. RESULTS: Across 220,544 clinic visits from 32,069 HIV-infected patients, age- and sex-specific average CD4+ cell count at ART initiation ranged from 83-136 cells/mm3, long term asymptotic CD4+ cell count ranged from 301-389 cells/mm3, and time to half of maximal CD4+ reconstitution ranged from 3.57-5.68 months. CD4+ cell count at ART initiation and asymptotic CD4+ cell count were 1.28 (95% CI: 1.18-1.40) and 1.25 (95% CI: 1.20-1.31) times higher, respectively, for females compared to males in the youngest age group (19-29 years). Older patients started treatment at higher CD4+ counts but experienced slower CD4+ recovery than younger adults. Treatment initiation at greater CD4+ cell counts was correlated with greater asymptotic CD4+ cell counts within all sex and age groups. CONCLUSION: Older adults should initiate care early in disease progression because total immune reconstitution potential and rate of reconstitution appears to decrease with age. Targeted HIV testing and care linkage remains crucial for patient populations who tend to initiate treatment at lower CD4+ cell counts, including males and younger adults.

PMID- 27716819 TI - A Phase I Dose Escalation Study of the Triple Angiokinase Inhibitor Nintedanib Combined with Low-Dose Cytarabine in Elderly Patients with Acute Myeloid Leukemia. AB - : Nintedanib (BIBF 1120), a potent multikinase inhibitor of VEGFR-1/-2/-3, FGFR 1/-2/-3 and PDGFR-alpha/-beta, exerts growth inhibitory and pro-apoptotic effects in myeloid leukemic cells, especially when used in combination with cytarabine. This phase I study evaluated nintedanib in combination with low-dose cytarabine (LDAC) in elderly patients with untreated or relapsed/refractory acute myeloid leukemia (AML) ineligible for intensive chemotherapy in a 3+3 design. Nintedanib (dose levels 100, 150, and 200 mg orally twice daily) and LDAC (20 mg subcutaneous injection twice daily for 10 days) were administered in 28-day cycles. Dose-limiting toxicity (DLT) was defined as non-hematological severe adverse reaction CTC grade >= 4 with possible or definite relationship to nintedanib. Between April 2012 and October 2013, 13 patients (median age 73 [range: 62-86] years) were enrolled. One patient did not receive study medication and was replaced. Nine (69%) patients had relapsed or refractory disease and 6 (46%) patients had unfavorable cytogenetics. The most frequently reported treatment-related adverse events (AE) were gastrointestinal events. Twelve SAEs irrespective of relatedness were reported. Two SUSARs were observed, one fatal hypercalcemia and one fatal gastrointestinal infection. Two patients (17%) with relapsed AML achieved a complete remission (one CR, one CRi) and bone marrow blast reductions without fulfilling PR criteria were observed in 3 patients (25%). One-year overall survival was 33%. Nintedanib combined with LDAC shows an adequate safety profile and survival data are promising in a difficult-to-treat patient population. Continuation of this trial with a phase II recommended dose of 2 x 200 mg nintedanib in a randomized, placebo-controlled phase II study is planned. The trial is registered to EudraCT as 2011-001086-41. TRIAL REGISTRATION: ClinicalTrials.gov NCT01488344. PMID- 27716820 TI - Gdown1 Associates Efficiently with RNA Polymerase II after Promoter Clearance and Displaces TFIIF during Transcript Elongation. AB - Pausing during the earliest stage of transcript elongation by RNA polymerase II (Pol II) is a nearly universal control point in metazoan gene expression. The substoichiometric Pol II subunit Gdown1 facilitates promoter proximal pausing in vitro in extract-based transcription reactions, out-competes the initiation/elongation factor TFIIF for binding to free Pol II and co-localizes with paused Pol II in vivo. However, we have shown that Gdown1 cannot functionally associate with the Pol II preinitiation complex (PIC), which contains TFIIF. In the present study, we determined at what point after initiation Gdown1 can associate with Pol II and how rapidly this competition with TFIIF occurs. We show that, as with the PIC, Gdown1 cannot functionally load into open complexes or complexes engaged in abortive synthesis of very short RNAs. Gdown1 can load into early elongation complexes (EECs) with 5-9 nt RNAs, but efficient association with EECs does not take place until the point at which the upstream segment of the long initial transcription bubble reanneals. Tests of EECs assembled on a series of promoter variants confirm that this bubble collapse transition, and not transcript length, modulates Gdown1 functional affinity. Gdown1 displaces TFIIF effectively from all complexes downstream of the collapse transition, but this displacement is surprisingly slow: complete loss of TFIIF stimulation of elongation requires 5 min of incubation with Gdown1. The relatively slow functional loading of Gdown1 in the presence of TFIIF suggests that Gdown1 works in promoter-proximal pausing by locking in the paused state after elongation is already antagonized by other factors, including DSIF, NELF and possibly the first downstream nucleosome. PMID- 27716822 TI - Signaling Properties of Chemerin Receptors CMKLR1, GPR1 and CCRL2. AB - Chemerin is a small chemotactic protein originally identified as the natural ligand of CMKLR1. More recently, two other receptors, GPR1 and CCRL2, have been reported to bind chemerin but their functional relevance remains poorly understood. In this study, we compared the binding and signaling properties of the three human chemerin receptors and showed differences in mode of chemerin binding and receptor signaling. Chemerin binds to all three receptors with low nanomolar affinities. However, the contribution of the chemerin C-terminus to binding efficiency varies greatly amongst receptors. By using BRET-based biosensors monitoring the activation of various G proteins, we showed that binding of chemerin and the chemerin 9 nonapeptide (149YFPGQFAFS157) to CMKLR1 activates the three Galphai subtypes (Galphai1, Galphai2 and Galphai3) and the two Galphao isoforms (Galphaoa and Galphaob) with potencies correlated to binding affinities. In contrast, no significant activation of G proteins was detected upon binding of chemerin to GPR1 or CCRL2. Binding of chemerin and the chemerin 9 peptide also induced the recruitment of beta-arrestin1 and 2 to CMKLR1 and GPR1, though to various degree, but not to CCRL2. However, the propensity of chemerin 9 to activate beta-arrestins relative to chemerin is higher when bound to GPR1. Finally, we showed that binding of chemerin to CMKLR1 and GPR1 promotes also the internalization of the two receptors and the phosphorylation of ERK1/2 MAP kinases, although with a different efficiency, and that phosphorylation of ERK1/2 requires both Galphai/o and beta-arrestin2 activation but not beta-arrestin1. Collectively, these data support a model in which each chemerin receptor displays selective signaling properties. PMID- 27716823 TI - Influence of Rotational Nucleosome Positioning on Transcription Start Site Selection in Animal Promoters. AB - The recruitment of RNA-Pol-II to the transcription start site (TSS) is an important step in gene regulation in all organisms. Core promoter elements (CPE) are conserved sequence motifs that guide Pol-II to the TSS by interacting with specific transcription factors (TFs). However, only a minority of animal promoters contains CPEs. It is still unknown how Pol-II selects the TSS in their absence. Here we present a comparative analysis of promoters' sequence composition and chromatin architecture in five eukaryotic model organisms, which shows the presence of common and unique DNA-encoded features used to organize chromatin. Analysis of Pol-II initiation patterns uncovers that, in the absence of certain CPEs, there is a strong correlation between the spread of initiation and the intensity of the 10 bp periodic signal in the nearest downstream nucleosome. Moreover, promoters' primary and secondary initiation sites show a characteristic 10 bp periodicity in the absence of CPEs. We also show that DNA natural variants in the region immediately downstream the TSS are able to affect both the nucleosome-DNA affinity and Pol-II initiation pattern. These findings support the notion that, in addition to CPEs mediated selection, sequence-induced nucleosome positioning could be a common and conserved mechanism of TSS selection in animals. PMID- 27716824 TI - Changes in Drivers' Visual Performance during the Collision Avoidance Process as a Function of Different Field of Views at Intersections. AB - The intersection field of view (IFOV) indicates an extent that the visual information can be observed by drivers. It has been found that further enhancing IFOV can significantly improve emergent collision avoidance performance at intersections, such as faster brake reaction time, smaller deceleration rate, and lower traffic crash involvement risk. However, it is not known how IFOV affects drivers' eye movements, visual attention and the relationship between visual searching and traffic safety. In this study, a driving simulation experiment was conducted to uncover the changes in drivers' visual performance during the collision avoidance process as a function of different field of views at an intersection by using an eye tracking system. The experimental results showed that drivers' ability in identifying the potential hazard in terms of visual searching was significantly affected by different IFOV conditions. As the IFOVs increased, drivers had longer gaze duration (GD) and more number of gazes (NG) in the intersection surrounding areas and paid more visual attention to capture critical visual information on the emerging conflict vehicle, thus leading to a better collision avoidance performance and a lower crash risk. It was also found that female drivers had a better visual performance and a lower crash rate than male drivers. From the perspective of drivers' visual performance, the results strengthened the evidence that further increasing intersection sight distance standards should be encouraged for enhancing traffic safety. PMID- 27716825 TI - Neighborhood Characteristics and Cardiovascular Risk among Older People in Japan: Findings from the JAGES Project. AB - Previous studies have found an association between neighborhood characteristics (i.e., aspects of the physical and social environment) and the incidence of cardiovascular disease (CVD) and elevated CVD risk. This study investigated the relationship between neighborhood characteristics and CVD risk among older people in Japan where research on this association is scarce. Data came from the Japan Gerontological Evaluation Study project; questionnaire data collected from 3,810 people aged 65 years or older living in 20 primary school districts in Aichi prefecture, Japan, was linked to a computed composite CVD risk score based on biomarker data (i.e., hemoglobin A1c, systolic blood pressure, diastolic blood pressure, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and estimated glomerular filtration rate). A sex-stratified multilevel linear regression analysis revealed that for male participants, living in neighborhoods with a higher perceived occurrence of traffic accidents and reduced personal safety was associated with an elevated CVD risk (coefficient = 1.08 per interquartile range increase, 95% confidence interval [CI] = 0.30 to 1.86) whereas males living in neighborhoods with a higher perceived proximity of exercise facilities had a lower risk (coefficient = -1.00, 95% CI = -1.78 to 0.21). For females, there was no statistically significant association between neighborhood characteristics and CVD risk. This study suggests that aspects of the neighborhood environment might be important for CVD morbidity and mortality in Japan, particularly among men. PMID- 27716826 TI - Meteorin-Like Shows Unique Expression Pattern in Bone and Its Overexpression Inhibits Osteoblast Differentiation. AB - The present study was performed to identify and characterize genes involved in osteoblasts function. Firstly, we constructed and sequenced a human osteoblast full-length cDNA library to screen for genes whose functions have not been reported and further identify these candidate genes through detecting the relationship with the activator protein-1 (AP-1) transcription factor complex using a dual luciferase reporter system. Only one gene, namely METRNL (Meteorin, glial cell differentiation regulator-like) has been screened out. We performed immunohistochemistry to analyze expression patterns in bone and established a stable transfection MG63 cell line of METRNL-EGFP fusion protein overexpression to analyze the function of METRNL in mineralized nodule formation. Immunohistochemistry showed METRNL expression in hypertrophic chondrocytes and osteoblasts lining trabecular bone surfaces. Overexpression of METRNL inhibited mineralized nodule formation by the MG63 osteosarcoma cell line. Thus, the identified gene, METRNL, which is associated with AP-1 transcription factor complex activity, has a unique expression pattern in bone. In addition, the anomalous expression of METRNL may inhibit bone cell differentiation. PMID- 27716827 TI - Predictors of Treatment Failure among Adult Antiretroviral Treatment (ART) Clients in Bale Zone Hospitals, South Eastern Ethiopia. AB - BACKGROUND: Treatment failure defined as progression of disease after initiation of ART or when the anti-HIV medications can't control the infection. One of the major concerns over the rapid scaling up of ART is the emergence and transmission of HIV drug resistant strains at the population level due to treatment failure. This could lead to the failure of basic ART programs. Thus this study aimed to investigate the predictors of treatment failure among adult ART clients in Bale Zone Hospitals, South east Ethiopia. METHODS: Retrospective cohort study was employed in four hospitals of Bale zone named Goba, Robe, Ginir and Delomena. A total of 4,809 adult ART clients were included in the analysis from these four hospitals. Adherence was measured by pill count method. The Kaplan Meier (KM) curve was used to describe the survival time of ART patients without treatment failure. Bivariate and multivariable Cox proportional hazards regression models were used for identifying associated factors of treatment failure. RESULT: The incidence rate of treatment failure was found 9.38 (95% CI 7.79-11.30) per 1000 person years. Male ART clients were more likely to experience treatment failure as compared to females [AHR = 4.49; 95% CI: (2.61-7.73)].Similarly, lower CD4 count (<100 m3/dl) at initiation of ART was found significantly associated with higher odds of treatment failure [AHR = 3.79; 95% CI: (2.46-5.84).Bedridden [AHR = 5.02; 95% CI: (1.98-12.73)] and ambulatory [AHR = 2.12; 95% CI: (1.08-4.07)] patients were more likely to experience treatment failure as compared to patients with working functional status. TB co-infected clients had also higher odds to experience treatment failure [AHR = 3.06; 95% CI: (1.72-5.44)]. Those patients who had developed TB after ART initiation had higher odds to experience treatment failure as compared to their counter parts [AHR = 4.35; 95% CI: (1.99-9.54]. Having other opportunistic infection during ART initiation was also associated with higher odds of experiencing treatment failure [AHR = 7.0, 95% CI: (3.19 15.37)]. Similarly having fair [AHR = 4.99 95% CI: (1.90-13.13)] and poor drug adherence [AHR = 2.56; 95% CI: (1.12-5.86)]were significantly associated with higher odds of treatment failure as compared to clients with good adherence. CONCLUSION: The rate of treatment failure in Bale zone hospitals needs attention. Prevention and control of TB and other opportunistic infections, promotion of ART initiation at higher CD4 level, and better functional status, improving drug adherence are important interventions to reduce treatment failure among ART clients in Southeastern Ethiopia. PMID- 27716828 TI - Retrospective Parameter Estimation and Forecast of Respiratory Syncytial Virus in the United States. AB - Recent studies have shown that systems combining mathematical modeling and Bayesian inference methods can be used to generate real-time forecasts of future infectious disease incidence. Here we develop such a system to study and forecast respiratory syncytial virus (RSV). RSV is the most common cause of acute lower respiratory infection and bronchiolitis. Advanced warning of the epidemic timing and volume of RSV patient surges has the potential to reduce well-documented delays of treatment in emergency departments. We use a susceptible-infectious recovered (SIR) model in conjunction with an ensemble adjustment Kalman filter (EAKF) and ten years of regional U.S. specimen data provided by the Centers for Disease Control and Prevention. The data and EAKF are used to optimize the SIR model and i) estimate critical epidemiological parameters over the course of each outbreak and ii) generate retrospective forecasts. The basic reproductive number, R0, is estimated at 3.0 (standard deviation 0.6) across all seasons and locations. The peak magnitude of RSV outbreaks is forecast with nearly 70% accuracy (i.e. nearly 70% of forecasts within 25% of the actual peak), four weeks before the predicted peak. This work represents a first step in the development of a real-time RSV prediction system. PMID- 27716829 TI - Analysis of Microstructure of the Cardiac Conduction System Based on Three Dimensional Confocal Microscopy. AB - The specialised conducting tissues present in the ventricles are responsible for the fast distribution of the electrical impulse from the atrio-ventricular node to regions in the subendocardial myocardium. Characterisation of anatomical features of the specialised conducting tissues in the ventricles is highly challenging, in particular its most distal section, which is connected to the working myocardium via Purkinje-myocardial junctions. The goal of this work is to characterise the architecture of the distal section of the Purkinje network by differentiating Purkinje cells from surrounding tissue, performing a segmentation of Purkinje fibres at cellular scale, and mathematically describing its morphology and interconnections. Purkinje cells from rabbit hearts were visualised by confocal microscopy using wheat germ agglutinin labelling. A total of 16 3D stacks including labeled Purkinje cells were collected, and semi automatically segmented. State-of-the-art graph metrics were applied to estimate regional and global features of the Purkinje network complexity. Two types of cell types, tubular and star-like, were characterised from 3D segmentations. The analysis of 3D imaging data confirms the previously suggested presence of two types of Purkinje-myocardium connections, a 2D interconnection sheet and a funnel one, in which the narrow side of a Purkinje fibre connect progressively to muscle fibres. The complex network analysis of interconnected Purkinje cells showed no small-world connectivity or assortativity properties. These results might help building more realistic computational PK systems at high resolution levels including different cell configurations and shapes. Better knowledge on the organisation of the network might help in understanding the effects that several treatments such as radio-frequency ablation might have when the PK system is disrupted locally.

AB - Emotional information is conveyed through verbal and nonverbal signals, with nonverbal cues often being considered the decisive factor in the judgment of others' emotional states. The aim of the present study was to examine how verbal and nonverbal cues are integrated by perceivers. More specifically, we tested whether the mismatch between verbal and nonverbal information was perceived as an expression of irony. Moreover, we investigated the effects of emotional intelligence on the impression of irony. The findings revealed that the mismatch between verbal and nonverbal information created the impression of irony. Furthermore, participants higher in emotional intelligence were faster at rating such stimuli as ironic expressions. PMID- 27716830 TI - Oligodendrocyte Development in the Absence of Their Target Axons In Vivo. AB - Oligodendrocytes form myelin around axons of the central nervous system, enabling saltatory conduction. Recent work has established that axons can regulate certain aspects of oligodendrocyte development and myelination, yet remarkably oligodendrocytes in culture retain the ability to differentiate in the absence of axons and elaborate myelin sheaths around synthetic axon-like substrates. It remains unclear the extent to which the life-course of oligodendrocytes requires the presence of, or signals derived from axons in vivo. In particular, it is unclear whether the specific axons fated for myelination regulate the oligodendrocyte population in a living organism, and if so, which precise steps of oligodendrocyte-cell lineage progression are regulated by target axons. Here, we use live-imaging of zebrafish larvae carrying transgenic reporters that label oligodendrocyte-lineage cells to investigate which aspects of oligodendrocyte development, from specification to differentiation, are affected when we manipulate the target axonal environment. To drastically reduce the number of axons targeted for myelination, we use a previously identified kinesin-binding protein (kbp) mutant, in which the first myelinated axons in the spinal cord, reticulospinal axons, do not fully grow in length, creating a region in the posterior spinal cord where most initial targets for myelination are absent. We find that a 73% reduction of reticulospinal axon surface in the posterior spinal cord of kbp mutants results in a 27% reduction in the number of oligodendrocytes. By time-lapse analysis of transgenic OPC reporters, we find that the reduction in oligodendrocyte number is explained by a reduction in OPC proliferation and survival. Interestingly, OPC specification and migration are unaltered in the near absence of normal axonal targets. Finally, we find that timely differentiation of OPCs into oligodendrocytes does not depend at all on the presence of target axons. Together, our data illustrate the power of zebrafish for studying the entire life-course of the oligodendrocyte lineage in vivo in an altered axonal environment. PMID- 27716832 TI - Introduction of High Throughput Magnetic Resonance T2-Weighted Image Texture Analysis for WHO Grade 2 and 3 Gliomas. AB - Reports have suggested that tumor textures presented on T2-weighted images correlate with the genetic status of glioma. Therefore, development of an image analyzing framework that is capable of objective and high throughput image texture analysis for large scale image data collection is needed. The current study aimed to address the development of such a framework by introducing two novel parameters for image textures on T2-weighted images, i.e., Shannon entropy and Prewitt filtering. Twenty-two WHO grade 2 and 28 grade 3 glioma patients were collected whose pre-surgical MRI and IDH1 mutation status were available. Heterogeneous lesions showed statistically higher Shannon entropy than homogenous lesions (p = 0.006) and ROC curve analysis proved that Shannon entropy on T2WI was a reliable indicator for discrimination of homogenous and heterogeneous lesions (p = 0.015, AUC = 0.73). Lesions with well-defined borders exhibited statistically higher Edge mean and Edge median values using Prewitt filtering than those with vague lesion borders (p = 0.0003 and p = 0.0005 respectively). ROC curve analysis also proved that both Edge mean and median values were promising indicators for discrimination of lesions with vague and well defined borders and both Edge mean and median values performed in a comparable manner (p = 0.0002, AUC = 0.81 and p < 0.0001, AUC = 0.83, respectively). Finally, IDH1 wild type gliomas showed statistically lower Shannon entropy on T2WI than IDH1 mutated gliomas (p = 0.007) but no difference was observed between IDH1 wild type and mutated gliomas in Edge median values using Prewitt filtering. The current study introduced two image metrics that reflect lesion texture described on T2WI. These two metrics were validated by readings of a neuro-radiologist who was blinded to the results. This observation will facilitate further use of this technique in future large scale image analysis of glioma. PMID- 27716833 TI - Can You Judge a Disease Host by the Company It Keeps? Predicting Disease Hosts and Their Relative Importance: A Case Study for Leishmaniasis. AB - Zoonoses are an important class of infectious diseases. An important element determining the impact of a zoonosis on domestic animal and human health is host range. Although for particular zoonoses some host species have been identified, until recently there have been no methods to predict those species most likely to be hosts or their relative importance. Complex inference networks infer potential biotic interactions between species using their degree of geographic co occurrence, and have been posited as a potential tool for predicting disease hosts. Here we present the results of an interdisciplinary, empirical study to validate a model based on such networks for predicting hosts of Leishmania (L.) mexicana in Mexico. Using systematic sampling to validate the model predictions we identified 22 new species of host (34% of all species collected) with the probability to be a host strongly dependent on the probability of co-occurrence of vector and host. The results confirm that Leishmania (L.) mexicana is a generalist parasite but with a much wider host range than was previously thought. These results substantially change the geographic risk profile for Leishmaniasis and provide insights for the design of more efficient surveillance measures and a better understanding of potential dispersal scenarios. PMID- 27716834 TI - Round Spermatid Injection Rescues Female Lethality of a Paternally Inherited Xist Deletion in Mouse. AB - In mouse female preimplantation embryos, the paternal X chromosome (Xp) is silenced by imprinted X chromosome inactivation (iXCI). This requires production of the noncoding Xist RNA in cis, from the Xp. The Xist locus on the maternally inherited X chromosome (Xm) is refractory to activation due to the presence of an imprint. Paternal inheritance of an Xist deletion (XpDeltaXist) is embryonic lethal to female embryos, due to iXCI abolishment. Here, we circumvented the histone-to-protamine and protamine-to-histone transitions of the paternal genome, by fertilization of oocytes via injection of round spermatids (ROSI). This did not affect initiation of XCI in wild type female embryos. Surprisingly, ROSI using DeltaXist round spermatids allowed survival of female embryos. This was accompanied by activation of the intact maternal Xist gene, initiated with delayed kinetics, around the morula stage, resulting in Xm silencing. Maternal Xist gene activation was not observed in ROSI-derived males. In addition, no Xist expression was detected in male and female morulas that developed from oocytes fertilized with mature DeltaXist sperm. Finally, the expression of the X-encoded XCI-activator RNF12 was enhanced in both male (wild type) and female (wild type as well as XpDeltaXist) ROSI derived embryos, compared to in vivo fertilized embryos. Thus, high RNF12 levels may contribute to the specific activation of maternal Xist in XpDeltaXist female ROSI embryos, but upregulation of additional Xp derived factors and/or the specific epigenetic constitution of the round spermatid-derived Xp are expected to be more critical. These results illustrate the profound impact of a dysregulated paternal epigenome on embryo development, and we propose that mouse ROSI can be used as a model to study the effects of intergenerational inheritance of epigenetic marks. PMID- 27716836 TI - Large-Scale Off-Target Identification Using Fast and Accurate Dual Regularized One-Class Collaborative Filtering and Its Application to Drug Repurposing. AB - Target-based screening is one of the major approaches in drug discovery. Besides the intended target, unexpected drug off-target interactions often occur, and many of them have not been recognized and characterized. The off-target interactions can be responsible for either therapeutic or side effects. Thus, identifying the genome-wide off-targets of lead compounds or existing drugs will be critical for designing effective and safe drugs, and providing new opportunities for drug repurposing. Although many computational methods have been developed to predict drug-target interactions, they are either less accurate than the one that we are proposing here or computationally too intensive, thereby limiting their capability for large-scale off-target identification. In addition, the performances of most machine learning based algorithms have been mainly evaluated to predict off-target interactions in the same gene family for hundreds of chemicals. It is not clear how these algorithms perform in terms of detecting off-targets across gene families on a proteome scale. Here, we are presenting a fast and accurate off-target prediction method, REMAP, which is based on a dual regularized one-class collaborative filtering algorithm, to explore continuous chemical space, protein space, and their interactome on a large scale. When tested in a reliable, extensive, and cross-gene family benchmark, REMAP outperforms the state-of-the-art methods. Furthermore, REMAP is highly scalable. It can screen a dataset of 200 thousands chemicals against 20 thousands proteins within 2 hours. Using the reconstructed genome-wide target profile as the fingerprint of a chemical compound, we predicted that seven FDA-approved drugs can be repurposed as novel anti-cancer therapies. The anti-cancer activity of six of them is supported by experimental evidences. Thus, REMAP is a valuable addition to the existing in silico toolbox for drug target identification, drug repurposing, phenotypic screening, and side effect prediction. The software and benchmark are available at https://github.com/hansaimlim/REMAP.

AB - Naringin, a flavanone glycoside extracted from various plants, has a wide range of pharmacological effects. In the present study, we investigated naringin's mechanism of action and its inhibitory effect on lipopolysaccharide-induced tumor necrosis factor-alpha and high-mobility group box 1 expression in macrophages, and on death in a cecal ligation and puncture induced mouse model of sepsis. Naringin increased heme oxygenase 1 expression in peritoneal macrophage cells through the activation of adenosine monophosphate-activated protein kinase, p38, and NF-E2-related factor 2. Inhibition of heme oxygenase 1 abrogated the naringin's inhibitory effect on high-mobility group box 1 expression and NF-kB activation in lipopolysaccharide-stimulated macrophages. Moreover, mice pretreated with naringin (200 mg/kg) exhibited decreased sepsis-induced mortality and lung injury, and alleviated lung pathological changes. However, the naringin's protective effects on sepsis-induced lung injury were eliminated by zinc protoporphyrin, a heme oxygenase 1 competitive inhibitor. These results revealed the mechanism underlying naringin's protective effect in inflammation and may be beneficial for the treatment of sepsis. PMID- 27716837 TI - Optical Coherence Tomography in the UK Biobank Study - Rapid Automated Analysis of Retinal Thickness for Large Population-Based Studies. AB - PURPOSE: To describe an approach to the use of optical coherence tomography (OCT) imaging in large, population-based studies, including methods for OCT image acquisition, storage, and the remote, rapid, automated analysis of retinal thickness. METHODS: In UK Biobank, OCT images were acquired between 2009 and 2010 using a commercially available "spectral domain" OCT device (3D OCT-1000, Topcon). Images were obtained using a raster scan protocol, 6 mm x 6 mm in area, and consisting of 128 B-scans. OCT image sets were stored on UK Biobank servers in a central repository, adjacent to high performance computers. Rapid, automated analysis of retinal thickness was performed using custom image segmentation software developed by the Topcon Advanced Biomedical Imaging Laboratory (TABIL). This software employs dual-scale gradient information to allow for automated segmentation of nine intraretinal boundaries in a rapid fashion. RESULTS: 67,321 participants (134,642 eyes) in UK Biobank underwent OCT imaging of both eyes as part of the ocular module. 134,611 images were successfully processed with 31 images failing segmentation analysis due to corrupted OCT files or withdrawal of subject consent for UKBB study participation. Average time taken to call up an image from the database and complete segmentation analysis was approximately 120 seconds per data set per login, and analysis of the entire dataset was completed in approximately 28 days. CONCLUSIONS: We report an approach to the rapid, automated measurement of retinal thickness from nearly 140,000 OCT image sets from the UK Biobank. In the near future, these measurements will be publically available for utilization by researchers around the world, and thus for correlation with the wealth of other data collected in UK Biobank. The automated analysis approaches we describe may be of utility for future large population based epidemiological studies, clinical trials, and screening programs that employ OCT imaging. PMID- 27716838 TI - Heteroresistant Vancomycin Intermediate Coagulase Negative Staphylococcus in the NICU: A Systematic Review. AB - CONTEXT: NICUs in the province of Quebec have seen an increase in hVICoNS, detected in the clinical laboratory. OBJECTIVE: To investigate the clinical relevance of hVICoNS on the course of infection, and to determine the prevalence of hVICoNS sepsis in the NICU. METHODS: We searched MEDLINE, EMBASE, and PubMed from 1 January 1980 to 1 July 2016. Both observational and interventional studies were considered eligible if they provided data on hVICoNS in the NICU population. Two investigators independently reviewed studies for data extraction. Data extracted included: number of CoNS cultures, prevalence of hVICoNS, and clonality of strains. RESULTS: Of the 613 studies identified, 19 studies were reviewed, and 5 studies included in the final review. No studies addressed the clinical significance of hVICoNS in the NICU. The prevalence of hVICoNS in the NICU varied greatly, ranging from 2.3% to 100%. LIMITATIONS: Publication bias could not be assessed, and risk of bias in some of the included studies due to small sample size and poor methods reporting. The quality of all included studies was low according to GRADE criteria, and the inclusion criteria restricted to either English or French studies. CONCLUSIONS: Our review suggests that heteroresistance to vancomycin is much more common than previously believed. Our search however did not identify any studies that explicitly assessed any clinical implications of hVICoNS infections, thereby highlighting the need for research to assess the true impact of hVICoNS infection and to determine its significance on patient mortality and morbidity in the NICU. PMID- 27716839 TI - Differences in Proinflammatory Property of Six Subtypes of Peroxiredoxins and Anti-Inflammatory Effect of Ligustilide in Macrophages. AB - BACKGROUND: Peroxiredoxins (Prxs) are proposed to function as damage-associated molecular patterns (DAMPs) and contribute to post-ischemic neuroinflammation and brain injury by activating Toll-like receptor (TLR) 4 at the acute and subacute phases after ischemic stroke. However, there are few studies concerning the inflammatory profiles of six distinct subtypes of Prxs (Prx1-Prx6). Our previous study demonstrated that the protective effect of ligustilide (LIG) against cerebral ischemia was associated with inhibition of neuroinflammatory response and Prx/TLR4 signaling in rats. Herein, the present study explored the inflammatory members of Prxs and the effect of LIG on their inflammatory responses in macrophages. METHODOLOGY/PRINCIPAL FINDINGS: The murine RAW264.7 macrophages were treated with each of exogenous recombinant Prxs at a range of 1 to 50 nM for 24 h. The WST-1 test showed that Prx3 exhibited a significant cytotoxicity, whereas the rest five Prxs did not affect cellular viability. The quantitative measurements with spectrometry or ELISA indicated that three subtypes, Prx1, Prx2 and Prx4, increased production of proinflammatory mediators, including nitric oxide (NO) metabolites, tumor necrosis factor-alpha (TNF-alpha), and interleukin-6 (IL-6) in a concentration-dependent manner. Immunostaining demonstrated that 20 nM Prx1, Prx2 or Prx4 significantly increased expression of TLR4 and iNOS and nuclear translocation of NF-kappaB p65. However, Prx5 and Prx6 showed no poinflammatory effect in macrophages. Remarkably, LIG treatment effectively inhibited the inflammatory response induced by Prx1, Prx2 and Prx4. CONCLUSION: Three members of Prxs, Prx1, Prx2 and Prx4, are inflammatory DAMPs that induce TLR4 activation and inflammatory response in macrophages, which is effectively inhibited by LIG. These results suggest that inflammatory Prxs activated macrophages may provide a novel cellular model for screening the potential inhibitors of DAMPs-associated inflammatory diseases such as stroke. Moreover, selective blocking strategies targeting the inflammatory subtypes of Prxs probably provide promising therapeutic approaches with a prolonged time window for stroke. PMID- 27716840 TI - Cadherin-2 Is Required Cell Autonomously for Collective Migration of Facial Branchiomotor Neurons. AB - Collective migration depends on cell-cell interactions between neighbors that contribute to their overall directionality, yet the mechanisms that control the coordinated migration of neurons remains to be elucidated. During hindbrain development, facial branchiomotor neurons (FBMNs) undergo a stereotypic tangential caudal migration from their place of birth in rhombomere (r)4 to their final location in r6/7. FBMNs engage in collective cell migration that depends on neuron-to-neuron interactions to facilitate caudal directionality. Here, we demonstrate that Cadherin-2-mediated neuron-to-neuron adhesion is necessary for directional and collective migration of FBMNs. We generated stable transgenic zebrafish expressing dominant-negative Cadherin-2 (Cdh2DeltaEC) driven by the islet1 promoter. Cell-autonomous inactivation of Cadherin-2 function led to non directional migration of FBMNs and a defect in caudal tangential migration. Additionally, mosaic analysis revealed that Cdh2DeltaEC-expressing FBMNs are not influenced to migrate caudally by neighboring wild-type FBMNs due to a defect in collective cell migration. Taken together, our data suggest that Cadherin-2 plays an essential cell-autonomous role in mediating the collective migration of FBMNs. PMID- 27716841 TI - Trajectories of Risk for Specific Readmission Diagnoses after Hospitalization for Heart Failure, Acute Myocardial Infarction, or Pneumonia. AB - BACKGROUND: The risk of rehospitalization is elevated in the immediate post discharge period and declines over time. It is not known if the extent and timing of risk vary across readmission diagnoses, suggesting that recovery and vulnerability after discharge differ by physiologic system. OBJECTIVE: We compared risk trajectories for major readmission diagnoses in the year after discharge among all Medicare fee-for-service beneficiaries hospitalized with heart failure (HF), acute myocardial infarction (AMI), or pneumonia from 2008 2010. METHODS: We estimated the daily risk of rehospitalization for 12 major readmission diagnostic categories after accounting for the competing risk of death after discharge. For each diagnostic category, we identified (1) the time required for readmission risk to peak and then decline 50% from maximum values after discharge; (2) the time required for readmission risk to approach plateau periods of minimal day-to-day change; and (3) the extent to which hospitalization risks are higher among patients recently discharged from the hospital compared with the general elderly population. RESULTS: Among >3,000,000 hospitalizations, the yearly rate of rehospitalization was 67.0%, 49.5%, and 55.3% after hospitalization for HF, AMI, and pneumonia, respectively. The extent and timing of risk varied by readmission diagnosis and initial admitting condition. Risk of readmission for gastrointestinal bleeding/anemia peaked particularly late after hospital discharge, occurring 10, 6, and 7 days after hospitalization for HF, AMI, and pneumonia, respectively. Risk of readmission for trauma/injury declined particularly slowly, requiring 38, 20, and 38 days to decline by 50% after hospitalization for HF, AMI, and pneumonia, respectively. CONCLUSIONS: Patterns of vulnerability to different conditions that cause rehospitalization vary by time after hospital discharge. This finding suggests that recovery of various physiologic systems occurs at different rates and that post-discharge interventions to minimize vulnerability to specific conditions should be tailored to their underlying risks. PMID- 27716842 TI - Effect of Preoperative Risk Group Stratification on Oncologic Outcomes of Patients with Adverse Pathologic Findings at Radical Prostatectomy. AB - BACKGROUND: Current National Comprehensive Cancer Network guidelines recommend postoperative radiation therapy based only on adverse pathologic findings (APFs), irrespective of preoperative risk group. We assessed whether a model incorporating both the preoperative risk group and APFs could predict long-term oncologic outcomes better than a model based on APFs alone. METHODS: We retrospectively reviewed 4,404 men who underwent radical prostatectomy (RP) at our institution between 1992 and 2014. After excluding patients receiving neoadjuvant therapy or with incomplete pathological or follow-up data, 3,092 men were included in the final analysis. APFs were defined as extraprostatic extension (EPE), seminal vesicle invasion (SVI), or a positive surgical margin (PSM). The adequacy of model fit to the data was compared using the likelihood ratio test between the models with and without risk groups, and model discrimination was compared with the concordance index (c-index) for predicting biochemical recurrence (BCR) and prostate cancer-specific mortality (PCSM). We performed multivariate Cox proportional hazard model and competing risk regression analyses to identify predictors of BCR and PCSM in the total patient group and each of the risk groups. RESULTS: Adding risk groups to the model containing only APFs significantly improved the fit to the data (likelihood-ratio test, p <0.001) and the c-index increased from 0.693 to 0.732 for BCR and from 0.707 to 0.747 for PCSM. A RP Gleason score (GS) >=8 and a PSM were independently associated with BCR in the total patient group and also each risk group. However, only a GS >=8 and SVI were associated with PCSM in the total patient group (GS >=8: hazard ratio [HR] 5.39 and SVI: HR 3.36) and the high-risk group (GS >=8: HR 6.31 and SVI: HR 4.05). CONCLUSION: The postoperative estimation of oncologic outcomes in men with APFs at RP was improved by considering preoperative risk group stratification. Although a PSM was an independent predictor for BCR, only a RP GS >=8 and SVI were associated with PCSM in the total patient and high-risk groups. PMID- 27716843 TI - Long-Term Durability of Tenofovir-Based Antiretroviral Therapy in Relation to the Co-Administration of Other Drug Classes in Routine Clinical Practice. AB - BACKGROUND: In clinical trials, toxicity leading to tenofovir disoproxil fumarate (TDF) discontinuation is rare (3% by 2 years); however in clinical practice it seems to be higher, particularly when TDF is co-administered with ritonavir boosted protease inhibitors (PI/r). Aims of this study were to assess the rate of TDF discontinuations in clinical practice and to identify factors associated with the risk of stopping TDF. METHODS: All antiretroviral treatment (ART)-naive patients initiating a TDF-based regimen were selected from the ICONA Foundation Study cohort. The primary outcome was TDF discontinuation regardless of the reason; secondary outcome measures were TDF discontinuation due to toxicity and selective TDF discontinuation (that is, TDF discontinuation or substitution, maintaining unchanged the remaining antiretroviral treatment). RESULTS: 3,618 ART naive patients were included: 54% started a PI/r-based and 46% a NNRTI-based based regimen. Two-hundred-seventy-seven patients discontinued TDF and reintroduced ART within 30 days without TDF. The probability of TDF discontinuation regardless of the reason was of 7.4% (95%CI:6.4-8.5) by 2 years and 14.1% (95%CI:12.2-16.1) by 5 years. The 5-year KM estimates in the PI/r vs. NNRTI group were 20.4% vs. 7.6%, respectively (log-rank p = 0.0001), for the outcome of stopping regardless of the reason, and 10.7% vs. 4.7% (p = 0.0001) for discontinuation due to toxicity. PI/r use and lower eGFR were associated with an increased risk of discontinuing TDF. CONCLUSION: In our cohort, the frequency of TDF discontinuations was higher than that observed in clinical trials. Co administration of TDF with PI/r was associated with an increased rate of TDF discontinuations. Further studies are needed to clarify the mechanisms that might have led to this outcome. PMID- 27716845 TI - Yolked Oocyte Dynamics Support Agreement between Determinate- and Indeterminate Method Estimates of Annual Fecundity for a Northeastern United States Population of American Shad. AB - Reports of American shad fecundity identify two important themes regarding egg production in fishes. First, geographic variation occurs and is biologically meaningful. Shad annual fecundity decreases with increasing latitude, but predicted lifetime fecundity does not, because of a counter-gradient of survival probability, all of which can explain the adaptive significance of natal homing. Second, the appropriate method of measuring fecundity depends on the pattern of oocyte development. Historically, the relatively simple determinate-fecundity method was used; however, a recent study in a Virginia river indicates that this method may be biased, requiring the more complicated indeterminate method. We address both themes with collections from the 2015 shad spawning run in the Connecticut River, USA. Criteria for using a determinate method were satisfied for this northern population: 1) a size gap evident in the oocyte size frequency distribution, indicating group-synchronous development of yolked oocytes; 2) a decline, early in spawning, in the standing stock of yolked oocytes; and 3) low levels of atresia at the end of spawning. The determinate-method estimate of American shad annual (2015) fecundity (303,000 +/- 73,400; mean +/- sd) overlapped historic estimates for this and a neighboring river. The indeterminate method estimate of annual (2015) fecundity (311,500 +/- 4,500 sd) was not significantly different from the determinate-method estimate (Student's t-test, P > 0.05). In contrast, indeterminate-method estimates of annual fecundity for a Virginia population were twice as high as that measured by the determinate method in the past. This can all be explained by fundamentally different patterns of oogenesis (i.e., group synchrony versus asynchrony with respect to yolk development) at different latitudes. American shad, which is distributed within its native range from the Canadian maritimes to Florida, USA (50-30 degrees N), may be particularly well suited to evaluate intra-specific variation in oocyte development, a relatively unexplored life history trait. PMID- 27716844 TI - SARAH Domain-Mediated MST2-RASSF Dimeric Interactions. AB - RASSF enzymes act as key apoptosis activators and tumor suppressors, being downregulated in many human cancers, although their exact regulatory roles remain unknown. A key downstream event in the RASSF pathway is the regulation of MST kinases, which are main effectors of RASSF-induced apoptosis. The regulation of MST1/2 includes both homo- and heterodimerization, mediated by helical SARAH domains, though the underlying molecular interaction mechanism is unclear. Here, we study the interactions between RASSF1A, RASSF5, and MST2 SARAH domains by using both atomistic molecular simulation techniques and experiments. We construct and study models of MST2 homodimers and MST2-RASSF SARAH heterodimers, and we identify the factors that control their high molecular stability. In addition, we also analyze both computationally and experimentally the interactions of MST2 SARAH domains with a series of synthetic peptides particularly designed to bind to it, and hope that our approach can be used to address some of the challenging problems in designing new anti-cancer drugs. PMID- 27716846 TI - Omeprazole Alleviates Aristolochia manshuriensis Kom-Induced Acute Nephrotoxicity. AB - Aristolochia manshuriensis Kom (AMK) is a member of the Aristolochiaceae family and is a well-known cause of aristolochic acid (AA) nephropathy. In this study, we investigated the potential of omeprazole (OM) to alleviate AMK-induced nephrotoxicity. We found that OM reduced mouse mortality caused by AMK and attenuated AMK-induced acute nephrotoxicity in rats. OM enhanced hepatic Cyp 1a1/2 and renal Cyp 1a1 expression in rats, as well as CYP 1A1 expression in human renal tubular epithelial cells (HKCs). HKCs with ectopic CYP 1A1 expression were more tolerant to AA than the control cells. Therefore, OM may alleviate AMK mediated acute nephrotoxicity through induction of CYP 1A1. We suggest that the coadministration of OM might be beneficial for reducing of AA-induced nephrotoxicity. PMID- 27716847 TI - Lowered Expression of Tumor Suppressor Candidate MYO1C Stimulates Cell Proliferation, Suppresses Cell Adhesion and Activates AKT. AB - Myosin-1C (MYO1C) is a tumor suppressor candidate located in a region of recurrent losses distal to TP53. Myo1c can tightly and specifically bind to PIP2, the substrate of Phosphoinositide 3-kinase (PI3K), and to Rictor, suggesting a role for MYO1C in the PI3K pathway. This study was designed to examine MYO1C expression status in a panel of well-stratified endometrial carcinomas as well as to assess the biological significance of MYO1C as a tumor suppressor in vitro. We found a significant correlation between the tumor stage and lowered expression of MYO1C in endometrial carcinoma samples. In cell transfection experiments, we found a negative correlation between MYO1C expression and cell proliferation, and MYO1C silencing resulted in diminished cell migration and adhesion. Cells expressing excess of MYO1C had low basal level of phosphorylated protein kinase B (PKB, a.k.a. AKT) and cells with knocked down MYO1C expression showed a quicker phosphorylated AKT (pAKT) response in reaction to serum stimulation. Taken together the present study gives further evidence for tumor suppressor activity of MYO1C and suggests MYO1C mediates its tumor suppressor function through inhibition of PI3K pathway and its involvement in loss of contact inhibition. PMID- 27716848 TI - Follicular Regulatory CD8 T Cells Impair the Germinal Center Response in SIV and Ex Vivo HIV Infection. AB - During chronic HIV infection, viral replication is concentrated in secondary lymphoid follicles. Cytotoxic CD8 T cells control HIV replication in extrafollicular regions, but not in the follicle. Here, we show CXCR5hiCD44hiCD8 T cells are a regulatory subset differing from conventional CD8 T cells, and constitute the majority of CD8 T cells in the follicle. This subset, CD8 follicular regulatory T cells (CD8 TFR), expand in chronic SIV infection, exhibit enhanced expression of Tim-3 and IL-10, and express less perforin compared to conventional CD8 T cells. CD8 TFR modestly limit HIV replication in follicular helper T cells (TFH), impair TFH IL-21 production via Tim-3, and inhibit IgG production by B cells during ex vivo HIV infection. CD8 TFR induce TFH apoptosis through HLA-E, but induce less apoptosis than conventional CD8 T cells. These data demonstrate that a unique regulatory CD8 population exists in follicles that impairs GC function in HIV infection. PMID- 27716849 TI - Increased CD40 Expression Enhances Early STING-Mediated Type I Interferon Response and Host Survival in a Rodent Malaria Model. AB - Both type I interferon (IFN-I) and CD40 play a significant role in various infectious diseases, including malaria and autoimmune disorders. CD40 is mostly known to function in adaptive immunity, but previous observations of elevated CD40 levels early after malaria infection of mice led us to investigate its roles in innate IFN-I responses and disease control. Using a Plasmodium yoelii nigeriensis N67 and C57BL/6 mouse model, we showed that infected CD40-/- mice had reduced STING and serum IFN-beta levels day-2 post infection, higher day-4 parasitemia, and earlier deaths. CD40 could greatly enhance STING-stimulated luciferase signals driven by the IFN-beta promoter in vitro, which was mediated by increased STING protein levels. The ability of CD40 to influence STING expression was confirmed in CD40-/- mice after malaria infection. Substitutions at CD40 TRAF binding domains significantly decreased the IFN-beta signals and STING protein level, which was likely mediated by changes in STING ubiquitination and degradation. Increased levels of CD40, STING, and ISRE driven luciferase signal in RAW Lucia were observed after phagocytosis of N67-infected red blood cells (iRBCs), stimulation with parasite DNA/RNA, or with selected TLR ligands [LPS, poly(I:C), and Pam3CSK4]. The results suggest stimulation of CD40 expression by parasite materials through TLR signaling pathways, which was further confirmed in bone marrow derived dendritic cells/macrophages (BMDCs/BMDMs) and splenic DCs from CD40-/-, TLR3-/- TLR4-/-, TRIF-/-, and MyD88-/ mice after iRBC stimulation or parasite infection. Our data connect several signaling pathways consisting of phagocytosis of iRBCs, recognition of parasite DNA/RNA (possibly GPI) by TLRs, elevated levels of CD40 and STING proteins, increased IFN-I production, and longer host survival time. This study reveals previously unrecognized CD40 function in innate IFN-I responses and protective pathways in infections with malaria strains that induce a strong IFN-I response, which may provide important information for better understanding and management of malaria. PMID- 27716851 TI - Mapping the Geometric Evolution of Protein Folding Motor. AB - Polypeptide chain has an invariant main-chain and a variant side-chain sequence. How the side-chain sequence determines fold in terms of its chemical constitution has been scrutinized extensively and verified periodically. However, a focussed investigation on the directive effect of side-chain geometry may provide important insights supplementing existing algorithms in mapping the geometrical evolution of protein chains and its structural preferences. Geometrically, folding of protein structure may be envisaged as the evolution of its geometric variables: phi, and psi dihedral angles of polypeptide main-chain directed by chi1, and chi2 of side chain. In this work, protein molecule is metaphorically modelled as a machine with 4 rotors phi, psi, chi1 and chi2, with its evolution to the functional fold is directed by combinations of its rotor directions. We observe that differential rotor motions lead to different secondary structure formations and the combinatorial pattern is unique and consistent for particular secondary structure type. Further, we found that combination of rotor geometries of each amino acid is unique which partly explains how different amino acid sequence combinations have unique structural evolution and functional adaptation. Quantification of these amino acid rotor preferences, resulted in the generation of 3 substitution matrices, which later on plugged in the BLAST tool, for evaluating their efficiency in aligning sequences. We have employed BLOSUM62 and PAM30 as standard for primary evaluation. Generation of substitution matrices is a logical extension of the conceptual framework we attempted to build during the development of this work. Optimization of matrices following the conventional routines and possible application with biologically relevant data sets are beyond the scope of this manuscript, though it is a part of the larger project design. PMID- 27716850 TI - Efficient Killing of High Risk Neuroblastoma Using Natural Killer Cells Activated by Plasmacytoid Dendritic Cells. AB - High-risk neuroblastoma (NB) remains a major therapeutic challenge despite the recent advent of disialoganglioside (GD2)-antibody treatment combined with interleukin (IL)-2 and granulocyte monocyte-colony stimulating factor (GM-CSF). Indeed, more than one third of the patients still die from this disease. Here, we developed a novel approach to improve the current anti-GD2 immunotherapy based on NK cell stimulation using toll-like receptor (TLR)-activated plasmacytoid dendritic cells (pDCs). We demonstrated that this strategy led to the efficient killing of NB cells. When the expression of GD2 was heterogeneous on NB cells, the combination of pDC-mediated NK-cell activation and anti-GD2 treatment significantly increased the cytotoxicity of NK cells against NB cells. Activation by pDCs led to a unique NK-cell phenotype characterized by increased surface expression of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), with increased expression of CD69 on CD56dim cytotoxic cells, and strong interferon-gamma production. Additionally, NB-cell killing was mediated by the TRAIL death-receptor pathway, as well as by the release of cytolytic granules via the DNAX accessory molecule 1 pathway. NK-cell activation and lytic activity against NB was independent of cell contact, depended upon type I IFN produced by TLR-9-activated pDCs, but was not reproduced by IFN-alpha stimulation alone. Collectively, these results highlighted the therapeutic potential of activated pDCs for patients with high-risk NB. PMID- 27716852 TI - Effects of Isaria fumosorosea on TYLCV (Tomato Yellow Leaf Curl Virus) Accumulation and Transmitting Capacity of Bemisia tabaci. AB - Tomato yellow leaf curl virus (TYLCV) is transmitted by the Bemisia tabaci pest Middle East-Asia Minor 1 (MEAM1) in China. Isaria fumosorosea is a fungal pathogen of B. tabaci. However, the effects of fungal infection on TYLCV expression and transmission by MEAM1 are unclear. In this study, potted tomatoes containing second instar nymphs of MEAM1 were treated with I. fumosorosea IfB01 strain and the relationship between fungal infection in MEAM1 and its TYLCV transmission capacity was investigated. The results indicated that a significantly (p < 0.05) decreased incidence of transmission of TYLCV-infected plants (ITYPs) transmitted by second instar nymphs of MEAM1 infected with fungus. Further, we found a negative correlation between fungal conidial concentrations and eclosion rates of MEAM1, and a positive correlation between ITYPs and eclosion. In addition, when each plant was exposed to three adults treated with fungus, a significantly decreased transmission of TYLCV (TYTE) was observed in the infected group. However, the incidence of TYLCV-carrying MEAM1 adults (ITYAs) was not significantly different in the infected and control groups (p < 0.05). Nevertheless, a significant decrease in viral accumulation using TYLCV AC2 gene as a marker was observed in the fungus-infected MEAM1. In conclusion, the results suggested that I. fumosorosea infection decreases TYLCV accumulation in MEAM1 and subsequently reduces its transmission. Our study provides new insights into the relationship between host plant, plant virus, insect vector, and entomopathogenic fungus. PMID- 27716853 TI - Evaluation of the diagnostic potential of ex vivo Raman spectroscopy in gastric cancers: fingerprint versus high wavenumber. AB - The aim of this study was to apply Raman spectroscopy in the high wavenumber (HW) region (2800 to 3000??cm?1) for ex vivo detection of gastric cancer and compare its diagnostic potential with that of the fingerprint (FP) region (800 to 1800??cm?1). Raman spectra were collected in the FP and HW regions to differentiate between normal mucosa (n=38) and gastric cancer (n=37). The distinctive Raman spectral differences between normal and cancer tissues are observed at 853, 879, 1157, 1319, 1338, 1448, and 2932??cm?1 and are primarily related to proteins, lipids, nucleic acids, collagen, and carotenoids in the tissue. In FP and HW Raman spectroscopy for diagnosis of gastric cancer, multivariate diagnostic algorithms based on partial-least-squares discriminant analysis, together with leave-one-sample-out cross validation, yielded diagnostic sensitivities of 94.59% and 81.08%, and specificities of 86.84% and 71.05%, respectively. Receiver operating characteristic analysis further confirmed that the FP region model performance is superior to that of the HW region model. Better differentiation between normal and gastric cancer tissues can be achieved using FP Raman spectroscopy and PLS-DA techniques, but the complementary natures of the FP and HW regions make both of them useful in diagnosis of gastric cancer. PMID- 27716854 TI - Comparison of Videostroboscopy to Stroboscopy Derived From High-Speed Videoendoscopy for Evaluating Patients With Vocal Fold Mass Lesions. AB - Purpose: Videostroboscopy (VS) uses an indirect physiological signal to predict the phase of the vocal fold vibratory cycle for sampling. Simulated stroboscopy (SS) extracts the phase of the glottal cycle directly from the changing glottal area in the high-speed videoendoscopy (HSV) image sequence. The purpose of this study is to determine the reliability of SS relative to VS for clinical assessment of vocal fold vibratory function in patients with mass lesions. Methods: VS and SS recordings were obtained from 28 patients with vocal fold mass lesions before and after phonomicrosurgery and 17 controls who were vocally healthy. Two clinicians rated clinically relevant vocal fold vibratory features using both imaging techniques, indicated their internal level of confidence in the accuracy of their ratings, and provided reasons for low or no confidence. Results: SS had fewer asynchronous image sequences than VS. Vibratory outcomes were able to be computed for more patients using SS. In addition, raters demonstrated better interrater reliability and reported equal or higher levels of confidence using SS than VS. Conclusion: Stroboscopic techniques on the basis of extracting the phase directly from the HSV image sequence are more reliable than acoustic-based VS. Findings suggest that SS derived from high-speed videoendoscopy is a promising improvement over current VS systems.

PMID- 27716857 TI - Thyroid Dysfunction and Ten-Year Incidence of Age-Related Macular Degeneration. AB - Purpose: Epidemiologic evidence of a relationship between thyroid dysfunction and age-related macular degeneration (AMD) is inconsistent and unclear. We aimed to assess the prospective associations between serum thyroid-stimulating hormone (TSH) and free thyroxine (FT4) measurements, as well as thyroid dysfunction (hyperthyroidism and hypothyroidism) and incidence of AMD. Methods: Categories of thyroid dysfunction were defined according to a serum TSH screen followed by serum FT4 assessment, and were available in 906 participants (aged 55+ years) at risk of AMD incidence (from 1997-1999 to 2007-2009). Continuous serum FT4 measures were available regardless of TSH screening results in 583 participants at risk of AMD incidence. Age-related macular degeneration was assessed from retinal photographs. Results: Participants with overt hyperthyroidism compared to those with normal thyroid function at baseline had increased risk of developing any incident AMD, after adjusting for age, sex, smoking, fish consumption, and variants in AMD susceptibility genes (CFH and ARMS2): odds ratio (OR) 3.51 (95% confidence interval [CI] 1.16-10.65). Participants who reported current use of thyroxine (n = 67; 7.3%) versus those who were not current users (n = 839) had a 68% increased risk of incident AMD, multivariable-adjusted OR 1.68 (95% CI 1.01 2.82). Similarly, participants who had ever been on thyroxine medication (n = 77; 8.4%) compared to those who had never been on thyroxine (n = 829) also had a higher risk of any AMD, multivariable-adjusted OR 1.91 (95% CI 1.18-3.09). Conclusions: Overt hyperthyroidism was independently associated with an increased risk of incident AMD. Thyroxine usage in older adults was also positively associated with incidence of AMD.

Many empirically tested methods to address these social deficits are available, yet difficulties related to the establishment and maintenance of authentic friendships persist. Method: This viewpoint article (a) briefly reviews the current state of the science relative to social and friendship skills training for individuals with ASD, (b) considers the potential links (or lack thereof) between current social and friendship skill interventions for individuals with ASD and outcomes related to making and maintaining friends, (c) examines how friendship-related outcomes might be maximized, and (d) proposes a framework for intervention planning that may promote these valued outcomes. Results: There are several key concepts to consider in planning intervention targeting friendship as an outcome. These concepts include (a) equal status, (b) mutually motivating and authentic opportunities for interaction, and (c) frequent opportunities for interaction. Conclusions: There are many aspects about friendship development that cannot be controlled or contrived. Much is still to be learned about the achievement of better friendships for individuals with ASD. Reconceptualizing the way we design intervention may promote better outcomes for individuals on the autism spectrum. PMID- 27716858 TI - Towards a Theory of Learning for Naming Rehabilitation: Retrieval Practice and Spacing Effects. AB - Purpose: The purpose of this article was to examine how different types of learning experiences affect naming impairment in aphasia. Methods: In 4 people with aphasia with naming impairment, we compared the benefits of naming treatment that emphasized retrieval practice (practice retrieving target names from long term memory) with errorless learning (repetition training, which preempts retrieval practice) according to different schedules of learning. The design was within subjects. Items were administered for multiple training trials for retrieval practice or repetition in a spaced schedule (an item's trials were separated by multiple unrelated trials) or massed schedule (1 trial intervened between an item's trials). In the spaced condition, we studied 3 magnitudes of spacing to evaluate the impact of effortful retrieval during training on the ultimate benefits conferred by retrieval practice naming treatment. The primary outcome was performance on a retention test of naming after 1 day, with a follow up test after 1 week. Results: Group analyses revealed that retrieval practice outperformed errorless learning, and spaced learning outperformed massed learning at retention test and at follow-up. Increases in spacing in the retrieval practice condition yielded more robust learning of retrieved information. Conclusion: This study delineates the importance of retrieval practice and spacing for treating naming impairment in aphasia. PMID- 27716860 TI - Safety and effectiveness of a long, partially covered metal stent for endoscopic ultrasound-guided hepaticogastrostomy in patients with malignant biliary obstruction. AB - Background and study aims: Endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD) is potentially complicated by bile leak and stent migration. The aim of this study was to evaluate the safety and effectiveness of a long (>= 10 cm), partially covered metal stent (LP-CMS) for EUS-guided hepaticogastrostomy (EUS HGS) for malignant biliary obstruction. Both the stent length and the uncovered portion at the proximal end of the LP-CMS are designed to prevent stent migration. Patients and methods: A total of 33 patients undergoing EUS-HGS using an LP-CMS in four centers were retrospectively studied. Technical and clinical success, adverse events, and recurrent biliary obstruction were evaluated. Results: Gastric outlet obstruction (76 %) and surgically altered anatomy (15 %) were two major reasons for EUS-HGS. The technical and clinical success rates were 100 %. The median intragastric stent length was 54 mm. The adverse event rate was 9 %. No stent migration was observed. Recurrent biliary obstruction developed in 24 %, with a median cumulative time to recurrence of 8.5 months. Conclusions: EUS HGS using an LP-CMS for unresectable malignant biliary obstruction was safe and effective. PMID- 27716861 TI - Radiofrequency ablation for the management of occluded biliary metal stents. AB - Background and study aim: Obstruction of biliary self-expandable metal stents (SEMSs) is seen frequently. Radiofrequency ablation (RFA) causes tissue necrosis. This study aimed to assess the efficacy of RFA for management of occluded SEMS. Patients and methods: Patients with biliary malignancy and treated for an occluded SEMS were retrospectively reviewed. The study group comprised patients treated with RFA using an Habib endoprobe inside the SEMS. The control group comprised patients treated only with insertion of a plastic stent into an occluded SEMS. The end points were; 90-day stent patency rate, time to stent reocclusion, 30-day mortality, and 3 - and 6-month survival rates. Results: During the 5-year study period 25 patients with an occluded SEMS underwent RFA and 25 patients underwent a plastic stent placement only. Both groups were matched for age and diagnosis. Immediate biliary drainage was restored in all patients. In the RFA group, the stenosis was ablated successfully in 14 patients (56 %); ablation failed in 11 and a plastic stent was then inserted into the SEMS for these. The control group had only placement of a plastic stent across the stenosis. Stent patency rate at 90 days was 56 % and 24 % in the RFA and control groups, respectively (P = 0.04). The mean stent patency time was significantly longer in the RFA group compared to the control group (119.5 vs. 65.3 days, P = 0.03). Conclusion: The application of RFA for occluded SEMS improves stent patency. RFA is an alternative treatment of tissue ingrowth in malignant biliary obstruction. PMID- 27716862 TI - Effect of Body Position on Energy Expenditure of Preterm Infants as Determined by Simultaneous Direct and Indirect Calorimetry. AB - Background Indirect calorimetry is the standard method for estimating energy expenditure in clinical research. Few studies have evaluated indirect calorimetry in infants by comparing it with simultaneous direct calorimetry. Our purpose was (1) to compare the energy expenditure of preterm infants determined by these two methods, direct calorimetry and indirect calorimetry; and (2) to examine the effect of body position, supine or prone, on energy expenditure. Study Design We measured energy expenditure by simultaneous direct (heat loss by gradient-layer calorimeter corrected for heat storage) and indirect calorimetry (whole-body oxygen consumption and carbon dioxide production) in 15 growing preterm infants during two consecutive interfeeding intervals, once in the supine position and once in the prone position. Results The mean energy expenditure for all measurements in both positions did not differ significantly by the method used: 2.82 (standard deviation [SD] 0.42) kcal/kg/h by direct calorimetry and 2.78 (SD 0.48) kcal/kg/h by indirect calorimetry. The energy expenditure was significantly lower, by 10%, in the prone than in the supine position, whether examined by direct calorimetry (2.67 vs. 2.97 kcal/kg/h, p < 0.001) or indirect calorimetry (2.64 vs. 2.92 kcal/kg/h, p = 0.017). Conclusion Direct calorimetry and indirect calorimetry gave similar estimates of energy expenditure. Energy expenditure was 10% lower in the prone position than in the supine position. PMID- 27716863 TI - Severe Vitamin D Deficiency in Human Immunodeficiency Virus-Infected Pregnant Women is Associated with Preterm Birth. AB - Background Low maternal vitamin D has been associated with preterm birth (PTB). Human immunodeficiency virus (HIV)-infected pregnant women are at risk for PTB, but data on maternal vitamin D and PTB in this population are scarce. Methods In a cohort of Latin American HIV-infected pregnant women from the National Institute of Child Health and Human Development International Site Development Initiative protocol, we examined the association between maternal vitamin D status and PTB. Vitamin D status was defined as the following 25-hydroxyvitamin D levels: severe deficiency (< 10 ng/mL), deficiency (10-20 ng/mL), insufficiency (21-29 ng/mL), and sufficiency (>=30 ng/mL). PTB was defined as delivery at < 37 weeks' gestational age (GA). Logistic regression was used to assess the association between maternal vitamin D status and PTB. Results Of 715 HIV infected pregnant women, 13 (1.8%) were severely vitamin D deficient, 224 (31.3%) were deficient, and 233 were (32.6%) insufficient. Overall, 23.2% (166/715) of pregnancies resulted in PTB (median GA of PTBs = 36 weeks [interquartile range: 34-36]). In multivariate analysis, severe vitamin D deficiency was associated with PTB (odds ratio = 4.7, 95% confidence interval: 1.3-16.8]). Conclusion Severe maternal vitamin D deficiency is associated with PTB in HIV-infected Latin American pregnant women. Further studies are warranted to determine if vitamin D supplementation in HIV-infected women may impact PTB. PMID- 27716864 TI - Exogenous Carbohydrate Reduces Cortisol Response from Combined Mental and Physical Stress. AB - Combined mental and physical stress is associated with exacerbated cortisol production which may increase risk for the progression of cardiovascular disease in individuals working in high-stress occupations (e.g., firefighters, military personnel, etc.). Carbohydrate (CHO) ingestion prior to physical stress may attenuate cortisol concentrations. This project was the first to investigate the effect of CHO ingestion on cortisol response from combined mental and physical stress. 16 men 21-30 years old were randomly assigned a 6.6% CHO beverage or non CHO control 15 min prior to performing a dual-concurrent-stress challenge. This consisted of physical stress (i.e., steady state exercise) combined with computerized mental challenges. Blood was sampled 70, 40, and 15 min before exercise, immediately at onset of exercise, 10, 20, 30, 35 min during exercise, and 15, 30, 45, and 60 min after exercise. There was a significant main effect for treatment regarding mean cortisol concentrations (F=5.30, P=0.0219). The total area under curve for cortisol was less when CHO was ingested (T7=4.07, P=0.0048). These findings suggest that CHO ingestion immediately prior to combined mental and physical stress may attenuate cortisol responses. PMID- 27716865 TI - Breaking up Prolonged Sitting does not Alter Postprandial Glycemia in Young, Normal-Weight Men and Women. AB - A randomized, controlled, cross-over study was used to investigate the effects of breaking up prolonged sitting with low intensity physical activity on postprandial blood glucose concentrations in healthy, young, normal-weight adults. 14 men (n=6) and women (n=8) were assigned to 2.5 h of prolonged sitting (CON) and 2.5 h of prolonged sitting with 2-min bouts of walking every 20 min (LIPA). After ingesting a standardized test drink, capillary blood was sampled every 10 min to establish a postprandial blood glucose profile. Based on individual glucose responses, peak blood glucose, time-to-peak glucose, and incremental area under the glucose curve (iAUC) were determined. Paired sample t tests were used to detect differences between trials. Peak blood glucose (p=0.55) and iAUC (CON: 252 mmol.L-1.2.5 h-1 [163-340]; LIPA: 214 mmol.L-1.2.5 h-1 [146 282]; p=0.45) were not different between trials. Also, time-to-peak glucose was not different between LIPA and CON (p=0.37). Taking advantage of high temporal resolution blood glucose profiles, we showed that breaking up prolonged sitting with low-intensity physical activity does not alter the postprandial blood glucose response in young, healthy, normal-weight adults. Our results indicate that postprandial glycemic control is maintained during prolonged sitting in young, healthy adults. PMID- 27716866 TI - [Is DRG Coding too Important to be Left to Physicians? - Evaluation of Economic Efficiency by Health Economists in a University Medical Centre]. AB - Background: We investigated and evaluated the cost effectiveness of coding by health care economists in a centre for orthopaedics and trauma surgery in Germany, by quantifying and comparing the financial efficiency of physicians with basic knowledge of the DRG-system with the results of healthcare economists with in-depth knowledge (M.Sc.). In addition, a hospital survey was performed to establish how DRG-coding is being performed and the identity of the persons involved. Material and Methods: In a prospective and controlled study, 200 in patients were coded by a healthcare economist (study group). Prior to that, the same cases were coded by physicians with basic training in the DRG-system, who made up the control group. All cases were picked randomly and blinded without informing the physicians coding the controls, in order to avoid any Hawthorne effect. We evaluated and measured the effective weighting within the G-DRG, the DRG returns per patient, the overall DRG return, and the additional time needed. For the survey, questionnaires were sent to 1200 German hospitals. The completed questionnaire was analysed using a statistical program. Results: The return difference per patient between controls and the study group was significantly greater (2472 +/- 337 ?; p < 0.05); the overall return was raised by 494,500 ?. The mean additional time needed was 11.32 +/- 0.8 min per case, resulting in an increase in proceeds of 218 +/- 38 ? per minute. 2.5 % of all cases had to be devaluated by the health economist after the initial coding by the control group. Returned sheets of 60 hospitals were evaluated. The median level of DRG case reports was 1277 (2500-62,300). Coding was performed in 69 % of cases by doctors, 19 % by skilled specialists for DRG coding and in 8 % together. Overall satisfaction with the DRG was described by 61 % of respondents as good or excellent. Conclusion: Our prospective and controlled study quantifies the cost efficiency of health economists in a centre of orthopaedics and trauma surgery in Germany for the first time. We provide some initial evidence that health economists can enhance the CMI, the resulting DRG return per patient as well as the overall DRG return. Data from the survey shows that in many hospitals there is great reluctance to leave the coding to specialists only. PMID- 27716867 TI - [Are Higher Prices for Larger Femoral Heads in Total Hip Arthroplasty Justified from the Perspective of Health Care Economics? An Analysis of Costs and Effects in Germany]. AB - Background: In total hip arthroplasty (THA), femoral head diameter has not been regarded as a key parameter which should be restored when reconstructing joint biomechanics and geometry. Apart from the controversial discussion on the advantages and disadvantages of using larger diameter heads, their higher cost is another important reason that they have only been used to a limited extent. The goal of this study was to analyse the price structure of prosthetic heads in comparison to other components used in THA. A large group of patients with hip endoprostheses were evaluated with respect to the implanted socket diameter and thus the theoretically attainable head diameter. Materials and Methods: The relative prices of various THA components (cups, inserts, stems and ball heads) distributed by two leading German manufacturers were determined and analysed. Special attention was paid to different sizes and varieties in a series of components. A large patient population treated with THA was evaluated with respect to the implanted cup diameter and therefore the theoretically attainable head diameter. Results: The pricing analysis of the THA components of two manufacturers showed identical prices for cups, inserts and stems in a series. In contrast to this, the prices for prosthetic heads with a diameter of 36-44 mm were 11-50 % higher than for 28 mm heads. Identical prices for larger heads were the exception. The distribution of the head diameter in 2719 THA cases showed significant differences between the actually implanted and the theoretically attainable heads. Conclusion: There are proven advantages in using larger diameter ball heads in THA and the remaining problems can be solved. It is therefore desirable to correct the current pricing practice of charging higher prices for larger components. Instead, identical prices should be charged for all head diameters in a series, as is currently established practice for all other THA components. Thus when reconstructing biomechanics and joint geometry in THA, it should be possible to recover not only leg length, femoral offset and antetorsion of the femoral neck, but also to approximately restore the diameter of the femoral head and thereby optimise the functional outcome. PMID- 27716868 TI - Twelve-month quality of life improvement and all-cause mortality in elderly patients undergoing transcatheter aortic valve replacement. AB - PURPOSE: Restoration of quality of life (QoL) and improvement of clinical outcomes is crucial in elderly patients undergoing transcatheter aortic valve implantation (TAVI). We sought to evaluate changes in QoL and all-cause mortality 12 months after TAVI. METHODS: A total of 101 patients who underwent TAVI were included. Patients were followed for 12 months. QoL was assessed at baseline and at 1, 6 and 12 months after TAVI using EQ-5D-3L with a visual analog scale (VAS). RESULTS: Patients who reported some problems with mobility at baseline showed better mobility after 12 months (p = 0.001). On the other hand, those who reported issues with self-care, usual activity or pain did not show significant improvement (p = 0.41; p = 0.12; p = 0.27, respectively). Patients reporting anxiety at baseline improved 12 months later (p = 0.003). VAS score showed an incremental increase during follow-up (p<0.001). Transfemoral access was associated with higher VAS score values after 1 month (median (IQR): 65.0 (50.0 75.0) vs. 54.0 (50.0-60.0); p = 0.019) but not after 12 months (70.0 (62.5-80.0) vs. 67.5 (55.0-70.0); p = 0.07) as compared to non-transfemoral access. In multivariable regression analysis, only age and the presence of coronary chronic total occlusion were independently associated with VAS score at 12 months. In hospital, 1-, 6- and 12-month mortality rates were 6.9%, 10.9%, 15.8 and 17.8%, respectively. CONCLUSIONS: TAVI provides improved QoL with relatively good clinical outcomes. However, not all components of QoL may be improved. Patients treated with transfemoral access might have better QoL than those who had non transfemoral access, especially early after TAVI. PMID- 27716869 TI - Biopolyester-based systems containing naturally occurring compounds with enhanced thermo-oxidative stability. AB - BACKGROUND: This work presents a sustainable approach for the stabilization of polylactic acid (PLA) against thermo-oxidative aging. METHODS: Naturally occurring phenolic and polyphenolic compounds, such as ferulic acid (FerAc), vanillic acid (VanAc), quercetin (Querc) and vitamin E (VitE), were introduced into PLA. RESULTS: The preliminary characterization of the systems formulated containing different amounts of natural stabilizers showed that all compounds used acted as plasticizers, leading to a decrease in rheological functions with respect to neat PLA, without significantly modifying the crystallinity of the raw material. The study of the thermo-oxidative behavior of neat PLA and PLA/natural compound systems, performed by spectrometric and thermal analyses, indicated that all stabilizers considered were able to exert a remarkable antioxidant action against thermo-oxidative phenomena. CONCLUSIONS: All natural compounds considered are thus proposed as ecofriendly stabilizers, to get fully bio-based polymer systems with enhanced thermo-oxidative stability, suitable for biomedical applications. PMID- 27716870 TI - Effect of cold drawing on mechanical properties of biodegradable fibers. AB - PURPOSE: Biodegradable polymers are currently gaining importance in several fields, because they allow mitigation of the impact on the environment related to disposal of traditional, nonbiodegradable polymers, as well as reducing the utilization of oil-based sources (when they also come from renewable resources). Fibers made of biodegradable polymers are of particular interest, though, it is not easy to obtain polymer fibers with suitable mechanical properties and to tailor these to the specific application. The main ways to tailor the mechanical properties of a given biodegradable polymer fiber are based on crystallinity and orientation control. However, crystallinity can only marginally be modified during processing, while orientation can be controlled, either during hot drawing or cold stretching. In this paper, a systematic investigation of the influence of cold stretching on the mechanical and thermomechanical properties of fibers prepared from different biodegradable polymer systems was carried out. METHODS: Rheological and thermal characterization helped in interpreting the orientation mechanisms, also on the basis of the molecular structure of the polymer systems. RESULTS AND CONCLUSIONS: It was found that cold drawing strongly improved the elastic modulus, tensile strength and thermomechanical resistance of the fibers, in comparison with hot-spun fibers. The elastic modulus showed higher increment rates in the biodegradable systems upon increasing the draw ratio. PMID- 27716871 TI - Controlled release of strontium through neutralization reaction within a methoxy(polyethylene glycol)-polyester hydrogel. AB - BACKGROUND: The aim of this study was to develop a minimally invasive hydrogel system that can release strontium ions, an element that has been shown to increase osteoblast proliferation and prohibit bone resorption, in a controlled manner. METHODS: SrCO3 was selected as the salt of choice due to potential acid neutralization reaction between SrCO3 and degradation by-products of methoxy(polyethylene glycol)-co-poly(lactic-co-glycolic acid) (mPEG-PLGA): namely, lactic acid and glycolic acid. SrCO3 was incorporated into mPEG-PLGA hydrogel, and the system was assessed for gelation properties, drug release and biocompatibility. RESULTS: SrCO3 incorporation at hydrogel to SrCO3 ratios of 5:1, 3:1 and 1:1 (wt%) did not compromise the thermosensitivity of mPEG-PLGA hydrogels. Furthermore, incorporation of SrCO3 at 1:1 ratio prevented copolymer self-catalysis and decreased hydrogel weight loss from 85% to 61% in vitro after 30 days. During the 30-day time frame, zero-order strontium release was observed and was correlated to hydrogel degradation and acidity. The addition of SrCO3 also improved in vivo hydrogel biocompatibility, due to moderation of acidic microenvironment and amelioration of inflammatory response. CONCLUSIONS: These results showed that the described system is suitable for the extended release of strontium and exhibits potential for localized treatment for osteoporosis or as a bone void filler. PMID- 27716873 TI - The current status of PARP inhibitors in ovarian cancer. AB - Recent advances in our understanding of the molecular biology of epithelial ovarian cancer have led to the development of a number of targeted therapies, including poly-ADP-ribose polymerase (PARP) inhibitors. PARP inhibitors are a novel class of therapeutic agents that target tumors with deficiencies in the homologous recombination DNA repair pathway. Early studies have shown significant efficacy for PARP inhibitors in patients with germline BRCA1/2 mutations. It has become evident that BRCA wild-type patients with other defects in the homologous recombination repair pathway benefit from this therapeutic approach. Importantly, companion homologous recombination deficiency scores are being developed to help guide the selection of patients most likely to gain clinical benefit from PARP inhibition. Olaparib, the first and most extensively investigated PARP inhibitor, is now licensed in Europe for maintenance treatment of patients with platinum sensitive relapsed BRCA-mutated (germline or somatic) high-grade serous ovarian cancer who have responded to platinum-based chemotherapy. In the United States, olaparib is licensed for treatment of patients with germline BRCA-mutated ovarian cancer who have received 3 or more lines of chemotherapy. There are a number of other PARP inhibitors in late phase clinical development in ovarian cancer including rucaparib, niraparib, veliparib, and talazoparib. This review will focus on the current evidence for PARP inhibitors in ovarian cancer and discuss ongoing clinical trials and future research directions in this rapidly evolving area. PMID- 27716872 TI - Bioencapsulation technologies in tissue engineering. AB - Bioencapsulation technologies have played an important role in the developing successes of tissue engineering. Besides offering immunoisolation, they also show promise for cell/tissue banking and the directed differentiation of stem cells, by providing a unique microenvironment. This review describes bioencapsulation technologies and summarizes their recent progress in research into tissue engineering. The review concludes with a brief outlook regarding future research directions in this field. PMID- 27716875 TI - Advantage of deep inspiration breath hold in left-sided breast cancer patients treated with 3D conformal radiotherapy. AB - PURPOSE: To compare 3D-conformal radiotherapy (3D-CRT) treatment plans based on free-breathing (FB) and deep inspiration breath hold (DIBH) and investigated whether DIBH technique enables a decrease of cardiac left anterior descending coronary artery (LADCA) and lungs dose with respect to the FB. METHODS: Twenty three left-sided breast cancer patients referred for breast radiotherapy were included. The planning target volume (PTV) encompassed the breast and organs at risk including heart, LADCA, lungs, and contralateral breast, which were contoured in FB and DIBH CT scans. Dose to PTV was 50 Gy in 25 fractions. Two treatment plans were generated for each patient: FB-3D-CRT and DIBH-3D-CRT. Dosimetry parameters were obtained from dose volume histograms. Data were compared using the paired-sample Wilcoxon signed rank test. RESULTS: For heart, LADCA, and left lung, a significant dose reduction was found using DIBH technique. By using DIBH, an average reduction of 25% was observed in LADCA for the volume receiving 20 Gy and of 48% considering the mean heart dose. CONCLUSIONS: The DIBH technique results in a significant decrease of dose to the heart, LADCA, and left lung compared to FB. PMID- 27716874 TI - Temozolomide low-dose chemotherapy in newly diagnosed low-grade gliomas: activity, safety, and long-term follow-up. AB - PURPOSE: To explore the efficacy and toxicity of an extended schedule of temozolomide (50 mg/mq 1 week on/1 week off) in a population of newly diagnosed low-grade gliomas (LGG). METHODS: Primary endpoints were progression-free survival (PFS) at 12 and 24 months and response rate evaluated with Response Assessment in Neuro-Oncology Criteria. Secondary endpoints were clinical benefit (reduction of seizures frequency), reduction of steroid, and modifications of Karnofsky Performance Status. RESULTS: From 2006 to 2009, we enrolled 14 consecutive patients with newly diagnosed LGG: 8 grade II astrocytomas, 2 oligodendroglioma, and 4 oligo-astrocytoma. Temozolomide was administered for 18 cycles (mean) per patient (range 3-24 cycles). In 57.5% (n = 8), we observed stable disease, 28.5% (n = 4) presented a minor response, and 14% (n = 2) showed progression. Five patients presented early progression during the first year of treatment and the study was stopped. A relevant clinical benefit was observed in 85% of patients (seizure control). After 6 years of follow-up, only 4 patients died. Prolonged PFS was associated with 1p-19q codeletion over 1p-19q intact (35 vs 4 months; p<0.04) and IDH1 mutation over IDH1 wild-type (36 vs 6 months; p<0.009). CONCLUSIONS: The study was interrupted for the high rate of progression observed in the first 14 patients enrolled. However, our results show that an extended low dose of temozolomide presents interesting activity with objective response and clinical benefit, but does not seem to prevent progression in patients presenting unfavorable molecular prognostic factors. PMID- 27716876 TI - Vestibular schwannomas treated with Cyberknife(r): clinical outcomes. AB - PURPOSE: Fractionated stereotactic radiotherapy (FSR) is a recognized treatment for vestibular schwannomas (VS). This study's aim is to present clinical outcomes and local control (LC) results for patients with VS treated with FSR using the Cyberknife(r) (CK) in 2 French cancer centers. METHODS: Patients treated with FSR for VS between 2007 and 2012 were retrospectively analyzed. Local control was determined using follow-up MRI. The hearing preservation (HP) rate was determined by analyzing pretreatment and posttreatment audiograms. RESULTS: Forty patients were treated for VS with the CK in both centers. The mean maximal VS dimension was 18.3 mm (range 3-30). The median follow-up was 36 months and the LC was 97% at 3 years of follow-up and 89% after 5 years. The HP rate was 83% and no facial nerve impairment was reported. CONCLUSIONS: Our results in terms of LC and HP rate are congruent with similar studies that use the CK to treat VS. It appears that the CK is safe and efficient in VS management even for large lesions. Further studies with larger cohorts are warranted. PMID- 27716877 TI - Simultaneous integrated bilateral breast and nodal irradiation with volumetric arc therapy: case report and literature review. AB - AIM: For simultaneous bilateral breast cancer (SBBC) treatment, conventional radiotherapy (RT) has a number of critical shortcomings. Thus, the usefulness of volumetric arc therapy (VMAT) for SBBC is undeniable. CASE REPORT: A 34-year-old woman with SBBC received neoadjuvant chemotherapy followed by breast-conserving surgery and bilateral lymph node dissection. Given the conservative surgery and the nodal involvement after neoadjuvant chemotherapy, bilateral adjuvant RT to the breasts and regional nodes with doses of 50 Gy in 25 fractions and a simultaneous integrated boost (SIB) of 60 Gy to the surgical bed was proposed. Monoisocentric VMAT using 2 pairs of arcs was performed with adequate target dose coverage and low doses to the organs at risk. The results of this case were compared with those of previous studies in terms of RT technique and irradiated volumes. CONCLUSIONS: VMAT is feasible and safe in the treatment of SBBC with SIB and nodal irradiation. PMID- 27716878 TI - Data quality in rare cancers registration: the report of the RARECARE data quality study. AB - PURPOSE: Rare cancers represent 22% of all tumors in Europe; however, the quality of the data of rare cancers may not be as good as the quality of data for common cancer. The project surveillance of rare cancers in Europe (RARECARE) had, among others, the objective of assessing rare cancer data quality in population-based cancer registries (CRs). Eight rare cancers were considered: mesothelioma, liver angiosarcoma, sarcomas, tumors of oral cavity, CNS tumors, germ cell tumors, leukemia, and malignant digestive endocrine tumors. METHODS: We selected data on 18,000 diagnoses and revised, on the basis of the pathologic and clinical reports (but not on pathologic specimens), unspecified morphology and topography codes originally attributed by CR officers and checked the quality of follow-up of long term survivors of poor prognosis cancers. RESULTS: A total of 38 CRs contributed from 13 European countries. The majority of unspecified morphology and topography cases were confirmed as unspecified. The few unspecified cases that, after the review, changed to a more specific diagnosis increased the incidence of the common cancer histotypes. For example, 11% of the oral cavity epithelial cancers were reclassified from unspecified to more specific diagnoses: 8% were reclassified as squamous cell carcinoma (commoner) and only 1% as adenocarcinoma (rarer). The revision confirmed the majority of long-term survivors revealing a relative high proportion of mesothelioma long-term survivors. The majority of appendix carcinoids changed behavior from malignant to borderline lesions. CONCLUSIONS: Our study suggests that the problem of poorly specified morphology and topography cases is mainly one of difficulty in reaching a precise diagnosis. The awareness of the importance of data quality for rare cancers should increase among registrars, pathologists, and clinicians. PMID- 27716879 TI - 3D vision improves outcomes in early cervical cancer treated with laparoscopic type B radical hysterectomy and pelvic lymphadenectomy. AB - PURPOSE: To evaluate the alterations on surgical outcomes after of the implementation of 3D laparoscopic technology for the surgical treatment of early stage cervical carcinoma. METHODS: Data of patients undergoing type B radical hysterectomy (with or without bilateral salpingo-oophorectomy) and pelvic lymphadenectomy via 3D laparoscopy were compared with a historical cohort of patients undergoing type B radical hysterectomy via conventional laparoscopy. Complications (within 60 days) were graded per the Accordion severity system. RESULTS: Data of 75 patients were studied: 15 (20%) and 60 (80%) patients undergoing surgery via 3D laparoscopy and conventional laparoscopy, respectively. Baseline patient characteristics as well as pathologic findings were similar between groups (p>0.1). Patients undergoing 3D laparoscopy experienced a trend toward shorter operative time than patients undergoing conventional laparoscopy (176.7 +/- 74.6 vs 215.9 +/- 61.6 minutes; p = 0.09). Similarly, patients undergoing 3D laparoscopic radical hysterectomy experienced shorter length of hospital stay (2 days, range 2-6, vs 4 days, range 3-11; p<0.001) in comparison to patients in the control group, while no difference in estimated blood loss was observed (p = 0.88). No between-group difference in complication rate was observed. CONCLUSIONS: 3D technology is a safe and effective way to perform type B radical hysterectomy and pelvic node dissection in early-stage cervical cancer. Further large prospective studies are warranted in order to assess the cost effectiveness of the introduction of 3D technology in comparison to robotic assisted surgery. PMID- 27716880 TI - Peritoneal metastases from adrenal cortical carcinoma treated by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. AB - PURPOSE: Adrenal cortical carcinoma is a rare cancer that often presents in an advanced stage. Not only systemic metastases but also local recurrence and peritoneal metastases prevent long-term survival in these patients. METHODS: A profoundly symptomatic patient with extensive peritoneal metastases and local recurrence was treated using cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) with melphalan as the chemotherapy agent. RESULTS: Relative sparing of the small bowel within the abdomen and pelvis allowed a visible complete resection of all cancer. The HIPEC with melphalan was used to control microscopic residual disease. Similar surgical technology used in this patient could be used to prevent local recurrence and peritoneal metastases in patients at the time of resection of the primary adrenal cortical carcinoma. CONCLUSIONS: Rare diseases may have peritoneal metastases as a component of disease progression and profit from treatment with CRS plus HIPEC. The clinical features suggesting a favorable outcome from this combined treatment are relative sparing of small bowel and its mesentery, absence of disease outside the abdomen, low-grade disease, or limited extent of high-grade disease. PMID- 27716881 TI - "What if...": decisional regret in patients who discontinued active surveillance. AB - PURPOSE: To investigate the presence of regret in patients about having followed an active surveillance (AS) protocol. The secondary aim was to identify variables that influence regret. METHODS: From February 2006 to May 2014, 204 patients discontinued the AS protocols and were invited to enter the study. Sociodemographic variables were collected at AS enrollment, together with health related quality of life (Functional Assessment of Cancer Therapy-Prostate version [FACT-P]) and coping (Mini-Mental Adjustment to Cancer). Patients were asked to complete a Treatment Regret Scale as well as the FACT-P questionnaire. Clinical data were gathered, as well as time of stay within the AS protocol, reason for discontinuing AS, kind of post-AS treatment, and time elapsed since AS discontinuation. Questionnaires were completed by 105 patients (51.5% of those who had been invited to enter the study). RESULTS: Most of the patients had a low or null degree of regret on the Treatment Regret Scale from 0 to 100 (82/105 patients [78.1%] obtained a score <30, and about 30% of the sample had a score equal to zero). Only 5 patients (4.7%) scored 60 or more, indicating some degree of regret. None of the statistical tests between regret scores and a number of analyzed variables reached significance. CONCLUSIONS: These results show that the degree of regret about following an AS protocol and after its discontinuation because of entering active treatment was very low. The regret after AS was not related to sociodemographic or clinical factors. PMID- 27716882 TI - Bilateral lymph node micrometastases and seminal vesicle invasion associated with same clinical predictors in localized prostate cancer. AB - AIM: To determine clinical factors associated with multiple bilateral lymph node micrometastases and seminal vesicle invasion (pT3b) in organ-confined prostate cancer (PCa). METHODS: The study excluded patients under androgen deprivation, with lymph node involvement (cN1 status), and having undergone unilateral pelvic lymph node dissection (PLND) during radical prostatectomy (RP). Lymph node micrometastases were classified as unilateral (pN1m) and bilateral (pN1b). Analysis considered multivariate multinomial logistic regression models. RESULTS: Between January 2013 and March 2015, 140 patients underwent PLND during RP. Lymph node micrometastases were detected in 28 cases (20%) including pN1m in 19 (13.6%) and pN1b in 9 (6.4%). Independent clinical predictors of pN1b included prostate specific antigen (PSA, ug/L) >12.5 (odds ratio [OR] = 43.0), proportion of positive biopsy cores (PBC) >0.57 (OR = 6.7), and biopsy Gleason grade (bGG) >3 (OR = 7.5). Independent pT3b predictors included PSA>12.5 (OR = 3.8), PBC>0.57 (OR = 4.1), and bGG>3 (OR = 3.8). CONCLUSIONS: In cN0 patients with localized PCa undergoing PLND, a nonnegligible rate of multiple lymph node micrometastases was detected (32.2%). In the natural history of PCa, there is a close association between pT3b and pN1b disease. Prostate cancer patients who are at high risk of extraglandular extension need selective pelvic staging by multiparametric magnetic resonance imaging to assess seminal vesicle invasion. Operated patients with pT3b and pNx status need close PSA monitoring because of the high probability of occult multiple bilateral lymph node micrometastases. PMID- 27716883 TI - LODDS is superior to lymph node ratio for the prognosis of node-positive rectal cancer patients treated with preoperative radiotherapy. AB - PURPOSE: Yielding pathologic-lymph node ratio (yp-LNR) was considered to be a better staging system than yp-N stage in rectal cancer patients treated with preoperative radiotherapy (pre-RT). We aimed to compare the predictive ability of yielding pathologic log odds of positive lymph nodes (yp-LODDS) with that of yp LNR for cancer-specific survival (CSS) in stage III rectal cancer patients treated with pre-RT. METHODS: We analyzed stage III rectal cancer patients treated with pre-RT in the Surveillance, Epidemiology and End Results (SEER) database. Patients were classified into 4 groups, yp-LNR1 to 4, based on the LNR cutoff points 0.25, 0.50, and 0.75. Subjects were categorized into 5 groups, yp LODDS1 to yp-LODDS5, based on the LODDS cutoff points -1, 0, 1, and 2. Univariate and multivariate Cox proportional hazards models were performed to analyze the risk factors for survival outcome. RESULTS: A total of 4,612 patients were included from the SEER database. Patients in the yp-LNR4 group could be further divided into yp-LODDS4 and yp-LODDS5 groups with 5-year CSS of 47.6% and 31.5%, respectively (p<0.001). In the multivariate analysis without yp-LODDS, yp-LNR was an independent prognostic factor (hazard ratio [HR] 2.006, 95% confidence interval [CI] 1.619-2.484, p<0.001). However, after adjusting for yp-LODDS, yp LNR was no longer associated with CSS (p = 0.393), and yp-LODDS was identified as an independent prognostic factor (HR 1.274, 95% CI 1.069-1.520, p = 0.007). CONCLUSIONS: The prognostic value of yp-LNR can be confounded by yp-LODDS. In stage III rectal cancer patients treated with pre-RT, yp-LODDS has superior discrimination power over yp-LNR and can more accurately evaluate CSS. PMID- 27716884 TI - Conservative approach for a solitary fibrous tumor of the kidney. AB - INTRODUCTION: Solitary fibrous tumor (SFT) of the kidney represents a rare neoplasm, and its malignant potential seems to be scarce. Classically, a radical nephrectomy is regarded as the treatment of choice for this condition. CASE REPORT: We present the case of a 37-year-old male patient who underwent left robotic clampless partial nephrectomy of an SFT of the kidney. Our patient has been followed-up carefully, and at 15-month examination, he is free of recurrence. This is the second case of an SFT managed through a conservative approach. CONCLUSIONS: In our opinion, according to tumor's dimensions, partial nephrectomy may be considered for treating small SFTs. PMID- 27716885 TI - Mitomycin C from birth to adulthood. AB - Mitomycin C (MMC) intravesical therapy for "superficial" papillary bladder tumors was firstly introduced in the early seventies with promising results. In the following years, several pharmacokinetic studies investigated its mechanism of action to optimize the intravesical administration. Numerous studies confirmed thereafter both the ablative and the prophylactic efficacy and the low toxicity of MMC when intravesically given. In 1984, a complete response rate of 42% in 60 patients not responsive to thiotepa was reported with intravesical MMC at the dose of 40 mg diluted in 40 ml for 8 weeks. In the following decades, many large randomized studies showed the benefit of intravesical prophylaxis with MMC versus transurethral resection (TUR) alone. Since 2002, the role of adjuvant intravesical chemotherapy and of an early MMC instillation in preventing recurrence compared with TUR alone has been confirmed by large meta-analyses and stated by the European Association of Urology (EAU) guidelines. The need for further intravesical chemotherapy after the early instillation in patients at intermediate-high risk of recurrence has been proved by several trials. Although intravesical Bacillus Calmette-Guerin (BCG) is considered the best choice for high-risk patients and MMC for the low-risk group, both MMC and BCG can be given to prevent recurrence in intermediate-risk patients. However, the higher efficacy of BCG over MMC is evident only if maintenance regimen is administered. Despite its proven efficacy, immediate intravesical MMC is not yet fully entered in common clinical practice and efforts should be made by the urologists to optimize its adoption. PMID- 27716886 TI - The impact of core length on prostate cancer diagnosis during a standard 14-core prostate biopsy scheme. AB - INTRODUCTION: Even if many studies in the literature purposed to evaluate the improvement of the prostate biopsy (PBx), few studies assessed the diagnostic value of core length in PBx. In this study, we evaluated the length of needle cores sampled during transrectal PBx (TRUSBx) and its impact on cancer diagnosis in a standard 14-core scheme. METHODS: Medical records of 573 patients who underwent an initial TRUSBx with 14-cores scheme for suspicious prostate cancer (PCa) at our Department were reviewed. The PBx procedure and pathological evaluation were standardized. Cores lengths were compared in patients with versus without cancer, and were divided into group A and B, respectively. Statistical analysis was done to define an acceptable cut-off for biopsy length. RESULTS: The mean age of the entire cohort was 62.1 +/- 7.2 years, while median total prostate specific antigen (PSA) and prostate volume were 4.2 ng/ml and 44.7 ml, respectively. PCa was showed in 33.3% of patients. Mean core length in group A versus B was 11.9 +/- 3.9 versus 11.1 +/- 3.2 mm (p = 0.016). Thus, core lengths were significantly longer in patients with cancer. There were no statistically significant differences when we considered the whole length of cores sampled from the right lobe (p = 0.58) and left lobe (p = 0.34). CONCLUSIONS: The cancer detection rates in cores may be increased by core length in PCa patients during a TRUSBx. Our results suggest a core length of greater than 11.8 mm as a cut-off for quality warranty. PMID- 27716887 TI - Intravesical electro-osmotic administration of mitomycin C. AB - Bladder cancer is very common and most cases are diagnosed as nonmuscle invasive disease, which is characterized by its propensity to recur and progress. Intravesical therapy is used to delay recurrence and progression, while cystectomy is reserved for patients who are refractory to transurethral resection and intravesical therapy. There is an increasing interest in methods to enhance the delivery of intravesical chemotherapeutic agents to improve efficacy. In vitro and in vivo studies demonstrated that electro-osmosis of mitomycin C (MMC) is more effective in delivering this drug into the urothelium, lamina propria, and superficial muscle layers of the bladder wall than is passive transport. Higher MMC tissue concentrations might have a clinical impact in the treatment of nonmuscle invasive bladder cancer (NMIBC). In randomized trials, intravesical electro-osmotic MMC was associated with superior response rate in high-risk NMIBC cancer, compared with passive diffusion MMC transport. New strategies such as intravesical Bacillus Calmette-Guerin (BCG) combined with electro-osmotic MMC as well as intravesical pre-operative electro-osmotic MMC provided promising results in terms of higher remission rates and longer remission times.Device-assisted intravesical chemotherapy may be a useful ancillary procedure in the treatment of NMIBC. Its evaluation must be planned with respect to the technical functioning of equipment and their use for a clear purpose to avoid the financial and human costs associated with incorrect therapies. PMID- 27716888 TI - Efficacy and safety of percutaneous nephrolithotomy with adult standard size instruments in children under 3 years of age: a 10 years single-center experience. AB - BACKGROUND: Using percutaneous nephrolitotomy (PCNL) with large adult instruments in treatment of pediatricurolithiasis is still in debate. This study was conducted to evaluate the efficacy and safety of PCNL with adult's instrument in treatment of patients less than 3 years old. METHODS: Data on patient characteristics and outcomes for 261 consecutive children undergoing PCNL at a Labbafinejad University Hospital were collected prospectively from September 2006 to February 2016. Thirty-two children, with 34 renal units, who were treated with PCNL were enrolled in the study. All PCNL procedures were performed via subcostal approach with one access tract in all of them. Postoperative complications were evaluated according to the modified Clavien grading system. RESULTS: The mean age of patients was 19.4 +/- 6.2 months. Two patients had bilateral stones; thus, PCNL was performed on 34 kidney units. The mean size of the largest stone diameter was 17.5 +/- 7.8 mm. The mean duration of procedures was 121.52 +/- 29.05 minutes, ranging from 60 to 180 minutes. The most common complication was fever (n = 9, 26.4%), and hemorrhage that needs transfusion was the second one (n = 4, 11.7%). Seventeen patients with complications were in the first degree of Clavien complication system and five of them were in the second degree. CONCLUSIONS: Due to our experience, utilizing PCNL with adult-sized instruments in management of urolithiasis in less than 3 years old children appeared to be effective and relatively safe. PMID- 27716890 TI - The removal of a stuck catheter: an alternative to Hong's technique. AB - The use of the tunneled central venous catheter (CVC) is steadily increasing worldwide as a means of vascular access for hemodialysis. The increased use of these devices, which often outlive the patients, and the extended time they are used are associated with more frequent complications. Among these, one of the emerging complications is that of the "embedded" or stuck catheter. This term refers to when the catheter cannot be removed after detaching the retention cuff. In medical literature, experiences with the removal of stuck catheters are described with the use of several different methods. Currently the most commonly used technique also considered the safest is "endoluminal dilation" also known as Hong's Technique, recently modified by Quaretti and Galli. Below, a new technique using a Vollmar ring is described for removing a stuck catheter as an alternative to Hong's technique, or after a failed attempt at using Hong's technique. PMID- 27716889 TI - Establishment of two data mining models of lung cancer screening based on three gene promoter methylations combined with telomere damage. AB - OBJECTIVE: To identify the significance of a support vector machine (SVM) model and a decision tree (DT) model for the diagnosis of lung cancer combined with the detection of fragile histidine triad (FHIT), RAS association domain family 1 (RASSF1A) and cyclin-dependent kinase inhibitor 2A (p16) promoter methylation levels and relative telomere length (RTL) of white blood cells from peripheral blood DNA. METHODS: The levels of p16, RASSF1A and FHIT promoter methylation and the RTL of white blood cells in peripheral blood DNA of 200 healthy individuals and 200 lung cancer patients were analyzed by SYBR Green-based quantitative methylation-specific PCR and quantitative PCR. Based on the 4 biomarkers, SVM and DT models were developed. RESULTS: The levels of FHIT, RASSF1A and p16 promoter methylation were 3.33 (1.86-6.40) and 2.85 (1.39-5.44) (p = 0.002); 27.62 (9.09 52.86) and 17.17 (3.86-50.87) (p = 0.038); and 0.59 (0.16-4.50) and 0.36 (0.06 4.00) (p = 0.008) in cases and controls, respectively. RTL was 0.93 +/- 0.32 and 1.16 +/- 0.57 (p<0.001). The areas under the receiver operating characteristic (ROC) curves of the Fisher discriminant analysis, SVM and DT models were 0.670 (0.569-0.761), 0.810 (0.719-0.882) and 0.810 (0.719-0.882), respectively. CONCLUSIONS: The SVM and DT models for diagnosing lung cancer were successfully developed through the combined detection of p16, RASSF1A and FHIT promoter methylation and RTL, which provided useful tools for screening lung cancer. PMID- 27716891 TI - Does pre- and post-angioplasty Doppler ultrasound evaluation help in predicting vascular access outcome? AB - BACKGROUND: Kidney Disease - Improving Global Outcomes (KDIGO) recommends post percutaneous transluminal angioplasty (PTA) <30% residual stenosis (RS) and hemodynamic parameters improvement. Primary end point: how post-PTA access blood flow (ABF) improvement predicts vascular access (VA) outcome. Secondary: compare Doppler ultrasound (DU) and angiography diagnostic accuracy; determine how other factors predict outcome. METHODS: Eighty patients. DU evaluation performed pre- and post-PTA. Several parameters recorded. Secondary patency verified after 6 months. RESULTS: Initial ABF 537 +/- 248 mL/min; final ABF 1013 +/- 354 mL/min. Number and location of stenosis was highly correlated between DU and angiography (p<0.001); central vessels mismatching. First semester overall survival was 63%; significantly better for fistulas (76%) than grafts (51.7%), p 0.044. Final RS>30% associated to better survival, p 0.038. Initial ABF<500 mL/min and multiple stenosis did not affect outcome (p>0.05). A >2-fold ABF increase had no significant impact on fistulas (p>0.05) but was significantly associated with worst outcomes in grafts (23.1% vs. 73.5%, p 0.009). Grafts had lower survival (HR 3.3, p 0.034). CONCLUSIONS: Although less accurate for central lesions, DU has a key role on VA surveillance, allowing a morphologic and hemodynamic assessment. Angioplasty is effective in preserving VA; however, it may increase restenosis due to accelerated neointimal hyperplasia. Current parameters are not useful. Trials addressing this issue are needed. PMID- 27716892 TI - Duplex ultrasound for the prediction of vascular events associated with arteriovenous fistulas in hemodialysis patients. AB - OBJECTIVE: To determine if duplex ultrasound (US) for arteriovenous fistulas (AVFs) can predict vascular events (VEs; thrombosis and stenosis). METHODS: Duplex US was performed for vascular access evaluation in 2557 maintenance hemodialysis (HD) patients between October 1, 2013 and March 31, 2016. Of these patients, 2184 patients were finally included in this study. AVF dysfunction was assessed using the brachial artery blood flow volume (Qa; mL/min), arterial blood flow resistance index (RI), and residual diameter of the fistula vein (RD; mm). Proximal, midpoint, and distal aspects of the fistulas were measured. The baseline measurements were the US assessments, and the endpoint was VEs requiring vascular access intervention therapy or vascular surgery. Associations of US findings and VEs were assessed with receiver operating characteristic curve analysis, log-rank analysis, and multivariate Cox hazard models. RESULTS: The mean Qa was 772.8 +/- 441.4 mL/min; RI, 0.56 +/- 0.1; and RD, 2.37 +/- 1.0 mm. The optimal Qa cut-off point was calculated as 581.5 mL/min, RI cut-off as 0.56, and RD cut-off as 1.85 mm. VEs were more frequent in patients with a Qa <581.5 mL/min than in those with a Qa >581.5 mL/min (p<0.001). In multivariate analysis, Qa, ferritin, transferrin saturation, and warfarin use were significantly associated with VEs. CONCLUSIONS: US evaluation of AVFs in HD patients is a simple method to predict the risks of thrombosis and fistula dysfunction. Qa, ferritin, transferrin saturation, and warfarin use might be associated with VEs. PMID- 27716893 TI - A modified de novo insertion technique for catheter replacement in elderly hemodialysis patients: a single clinic retrospective analysis. AB - PURPOSE: For patients who rely on a tunneled cuffed catheter, replacement or catheter removal is typically necessary. We recently performed a modified de novo insertion technique for catheter replacement in our practice. As the technique has not yet been studied comprehensively, we performed a retrospective study to evaluate the safety and efficacy of de novo placed catheter without delay for catheter replacement in elderly hemodialysis patients. METHODS: A retrospective review of 164 elderly patients was conducted during a period of three years. There were 84 patients in study group, as well as 80 patients in a control group, who had catheter replacement by guidewire exchange technique. Clinical follow-up data was collected. RESULTS: All catheters were placed successfully. The mean survival time per catheter was 641 catheter days (study group) and 485 catheter days (control group). The primary patency rates of 30 days were 97.7% (study group) and 90% (control group), respectively, with statistically significant difference (p = 0.04). The incidence of catheter infection was not statistically significantly different in both groups (p = 0.586), but the case of catheter dysfunction was significantly lower in study group compared to control group (p = 0.003). CONCLUSIONS: The de novo placed catheter without delay technique for catheter replacement near the pre-existing venotomy site is safe, and boasts similar infection rates with lower dysfunction rates compared to tunneled catheter insertion by guidewire exchange technique. PMID- 27716894 TI - Cognitive function may be a predictor of retinopathy progression in patients with type 2 diabetes. AB - PURPOSE: Microvascular and macrovascular complications of diabetes, such as retinopathy and nephropathy, progress over time and may be associated with cognitive decline. In this article, we aim to gain further insight into the association between cognitive function and retinopathy in type 2 diabetes. METHODS AND RESULTS: In this observational 8-year prospective study of 498 outpatients, demographic and clinical variables were monitored, along with retinopathy, depression, anxiety, and cognitive function. Baseline fundus photographs were available in 477 patients, 240 with no retinopathy, 110 with mild retinopathy, and 127 with moderate/more severe retinopathy. Of the first 2 groups, 279 patients were reevaluated after 8 years, of whom 181 still had no/mild retinopathy and 98 had progressed to more severe stages. On multivariate analysis, retinopathy progression was associated with being insulin-treated (p = 0.036), and worse cognitive function (p = 0.025) at baseline. CONCLUSIONS: Cognitive function may be an independent predictor of retinopathy progression. PMID- 27716895 TI - The biology of germ cell tumors in disorders of sex development. AB - Development of a malignant germ cell tumor, i.e., germ cell cancer (GCC) in individuals with disorders of sex development (DSD) depends on a number of (epi )genetic factors related to early gonadal- and germ cell development, possibly related to genetic susceptibility. Fetal development of germ cells is orchestrated by strict processes involving specification, migration and the development of a proper gonadal niche. In this review we will discuss the early (epi-)genetic events in normal and aberrant germ cell and gonadal development. Focus will be on the formation of the precursor lesions of GCC in individuals who have DSD. In our view, expression of the different embryonic markers in, and epigenetic profile of the precursor lesions reflects the developmental stage in which these cells are blocked in their maturation. Therefore, these are not a primary pathogenetic driving force. Progression later in life towards a full blown cancer likely depends on additional factors such as a changed endocrine environment in a susceptible individual. Genetic susceptibility is, as evidenced by the presence of specific risk genetic variants (SNPs) in patients with a testicular GCC, related to genes involved in early germ cell and gonadal development. PMID- 27716896 TI - Choroidal abnormalities in cafe-au-lait syndromes: a new differential diagnostic tool? AB - The best known cafe-au-lait syndrome is neurofibromatosis type 1 (NF1). Legius syndrome (LS) is another, rarer syndrome with cafe-au-lait macules (CALMs). In young patients their clinical picture is often indistinguishable. We investigated the presence of choroidal abnormalities in syndromes with CALMs as a candidate tool for a more efficient diagnosis. Thirty-four patients with NF1 (14 with a truncating mutation, 14 with a non-truncating mutation and 6 with unknown mutation) and 11 patients with LS. All patients underwent an ophthalmological examination. Infrared images were performed. Choroidal nodules were diagnosed in 65% of the NF1 group. About 71% of NF1 patients with a truncating mutation and 50% of patients with a non-truncating mutation were found to have nodules. Choroidal nodules were seen in 18% of the LS patients, never more than one nodule/eye was detected in this group. Choroidal nodules are more abundantly present in NF1 genotypes with truncating mutations. In contrast, the number of choroidal nodules in LS is comparable with their presence in healthy individuals. Especially at an early age, when the clinical picture is incomplete, the detection of choroidal nodules is of diagnostic value, and helps in an appropriate genetic counselling and follow-up. These results support the suggestion to include choroidal nodules to the diagnostic criteria for NF1. PMID- 27716897 TI - Birth and Adoptive Parent Antisocial Behavior and Parenting: A Study of Evocative Gene-Environment Correlation. AB - Negative parenting is shaped by the genetically influenced characteristics of children (via evocative rGE) and by parental antisocial behavior; however, it is unclear how these factors jointly impact parenting. This study examined the effects of birth parent and adoptive parent antisocial behavior on negative parenting. Participants included 546 families within a prospective adoption study. Adoptive parent antisocial behavior emerged as a small but significant predictor of negative parenting at 18 months and of change in parenting from 18 to 27 months. Birth parent antisocial behavior predicted change in adoptive father's (but not mother's) parenting over time. These findings highlight the role of parent characteristics and suggest that evocative rGE effects on parenting may be small in magnitude in early childhood. PMID- 27716899 TI - Prospective cohort study of laparoscopic and open hepatectomy for hepatocellular carcinoma. AB - BACKGROUND: The safety and feasibility of laparoscopic hepatectomy for hepatocellular carcinoma (HCC) with a diameter of 5 cm or less is well recognized. The role of laparoscopy in treating large HCC (5-10 cm) remains controversial. This prospective cohort study was undertaken to assess the short- and long-term outcomes of laparoscopic hepatectomy for large HCC and to compare this approach with open hepatectomy. METHODS: Patients with a solitary HCC (diameter 5-10 cm) who underwent open or laparoscopic hepatectomy were enrolled in a prospective observational study from January 2012 to April 2015. Perioperative and follow-up data were analysed. RESULTS: Some 128 patients underwent laparoscopic hepatectomy and 207 had an open hepatectomy. One and two perioperative deaths were reported in the laparoscopic and open groups respectively. Laparoscopic hepatectomy was converted to an open procedure in 12 (9.4 per cent) of 128 patients. More patients in the laparoscopic group underwent an anatomical hepatectomy than in the open group (45.3 versus 21.7 per cent; P = 0.001). The postoperative complication rate was 20.3 per cent for the laparoscopic group versus 35.7 per cent for the open group (P = 0.003). Mean(s.d.) duration of hospital stay was 11.4(3.1) and 15.8(7.7) days respectively (P < 0.001). One- and 3-year overall survival rates in the laparoscopic and open groups were 94.4 versus 93.6 per cent (P = 0.875), and 81.4 versus 82.2 per cent (P = 0.802), respectively. One- and 3-year disease-free survival rates were 89.4 versus 88.7 per cent (P = 0.825), and 67.3 versus 66.7 per cent (P = 0.902), respectively. CONCLUSION: Laparoscopic hepatectomy is safe and feasible for the treatment of patients with large HCC. PMID- 27716898 TI - Distinct patterns of cytolytic T-cell activation by different tumour cells revealed by Ca2+ signalling and granule mobilization. AB - Cancer-germline genes in both humans and mice have been shown to encode antigens susceptible to targeting by cytotoxic CD8 T effector cells (CTL). We analysed the ability of CTL to kill different tumour cell lines expressing the same cancer germline gene P1A (Trap1a). We previously demonstrated that CTL expressing a T cell receptor specific for the P1A35-43 peptide associated with H-2Ld , although able to induce regression of P1A-expressing P815 mastocytoma cells, were much less effective against P1A-expressing melanoma cells. Here, we analysed parameters of the in vitro interaction between P1A-specific CTL and mastocytoma or melanoma cells expressing similar levels of the P1A gene and of surface H-2Ld . The mastocytoma cells were more sensitive to cytolysis than the melanoma cells in vitro. Analysis by video-microscopy of early events required for target cell killing showed that similar patterns of increase in cytoplasmic Ca2+ concentration ([Ca2+ ]i) were induced by both types of P1A-expressing tumour cells. However, the use of CTL expressing a fluorescent granzyme B (GZMB-Tom) showed a delay in the migration of cytotoxic granules to the tumour interaction site, as well as a partially deficient GZMB-Tom exocytosis in response to the melanoma cells. Among surface molecules possibly affecting tumour-CTL interactions, the mastocytoma cells were found to express intercellular adhesion molecule-1, the ligand for LFA-1, which was not detected on the melanoma cells.

PMID- 27716900 TI - Measuring financial toxicity as a clinically relevant patient-reported outcome: The validation of the COmprehensive Score for financial Toxicity (COST). AB - BACKGROUND: Cancer and its treatment lead to increased financial distress for patients. To the authors' knowledge, to date, no standardized patient-reported outcome measure has been validated to assess this distress. METHODS: Patients with AJCC Stage IV solid tumors receiving chemotherapy for at least 2 months were recruited. Financial toxicity was measured by the COmprehensive Score for financial Toxicity (COST) measure. The authors collected data regarding patient characteristics, clinical trial participation, health care use, willingness to discuss costs, psychological distress (Brief Profile of Mood States [POMS]), and health-related quality of life (HRQOL) as measured by the Functional Assessment of Cancer Therapy: General (FACT-G) and the European Organization for Research and Treatment of Cancer (EORTC) QOL questionnaires. Test-retest reliability, internal consistency, and validity of the COST measure were assessed using standard-scale construction techniques. Associations between the resulting factors and other variables were assessed using multivariable analyses. RESULTS: A total of 375 patients with advanced cancer were approached, 233 of whom (62.1%) agreed to participate. The COST measure demonstrated high internal consistency and test-retest reliability. Factor analyses revealed a coherent, single, latent variable (financial toxicity). COST values were found to be correlated with income (correlation coefficient [r] = 0.28; P<.001), psychosocial distress (r = 0.26; P<.001), and HRQOL, as measured by the FACT-G (r = 0.42; P<.001) and by the EORTC QOL instruments (r = 0.33; P<.001). Independent factors found to be associated with financial toxicity were race (P = .04), employment status (P<.001), income (P = .003), number of inpatient admissions (P = .01), and psychological distress (P = .003). Willingness to discuss costs was not found to be associated with the degree of financial distress (P = .49). CONCLUSIONS: The COST measure demonstrated reliability and validity in measuring financial toxicity.

AB - BACKGROUND: To better inform clinical practice, this study was aimed at capturing patients' motivations for enrolling in phase 1 trials and at quantifying their expectations of the benefits, risks, and commitment associated with clinical trials and the impact of the initial consultation on their expectations. METHODS: This was a single-center, prospective, quantitative study of newly referred adult patients considering their first phase 1 oncology trial. Participants completed questionnaires before they were seen and an abbreviated follow-up version after their consultation. RESULTS: Questionnaires were completed by 396 (99%) and 301 (76%) before and after the clinic, respectively. Participants ranked the possibility of tumor shrinkage (84%) as the most important motivation for considering a phase 1 trial; this was followed by no alternative treatments (56%), their physician's recommendation (44%), and the fact that the research might benefit others (38%). When they were asked about the potential personal benefit, 43% predicted tumor shrinkage initially. After the consultation, this increased to 47%. Fourteen percent of patients expected a cure. When asked about risks, 71% of the participants expected moderate side effects. When asked about expectations of time commitments, a majority of patients did not anticipate weekly visits, although this was understood by 93% of patients after the consultation. Overall, patients were keen to consider trials and when asked before and after the consultation 72% and 84% were willing to enroll in studies, respectively. CONCLUSIONS: This study reports that more than 80% of patients enroll in early-phase clinical oncology trials motivated by the potential of a clinical benefit, with approximately half expecting tumor shrinkage and approximately a tenth anticipating a cure. The typical phase 1 response rate is 4% to 20%, and this discrepancy exemplifies the challenges faced by patients and healthcare professionals during their interactions for phase 1 studies.

PMID- 27716903 TI - Detection of IgE autoantibodies to BP180 and BP230 and their relationship to clinical features in bullous pemphigoid. AB - BACKGROUND: IgE autoantibodies are considered to be involved in the pathogenesis of bullous pemphigoid (BP), particularly inflammatory and erythematous phenotypes. OBJECTIVES: To develop reliable enzyme-linked immunosorbent assays (ELISAs) for the detection of IgE autoantibodies to both BP180 and BP230 in BP sera, and to compare the ELISA results with clinical features. METHODS: We used commercially available IgG ELISAs to develop IgE ELISAs for both BP180 and BP230. To determine the influence of excess amounts of IgG autoantibodies, all normal and BP sera were tested before and after IgG adsorption. The results of the IgE ELISAs were statistically compared with various ELISAs and various clinical parameters, including our own severity scores and BP phenotypes. RESULTS: IgG adsorption generally showed no changes in sensitivity and specificity for IgE ELISAs, although slight cross-reactivity of anti-IgE secondary antibody to IgG and interference of excess amounts of IgG autoantibodies to IgE reactivity were suggested. IgE autoantibodies to BP180 were found in 21 of 36 BP sera and IgE autoantibodies to BP230 were found in 18 of 36 BP sera. The results of IgG and IgE ELISAs for both BP180 and BP230 were well correlated. IgG and IgE anti-BP180 antibodies correlated with disease activity but IgG and IgE anti-BP230 autoantibodies did not. IgE anti-BP230 autoantibodies correlated with nodular phenotype but not erythematous phenotype. CONCLUSIONS: The results of this study indicated that IgE autoantibodies to both BP180 and BP230 are frequently detected in BP sera. IgE anti-BP180 autoantibodies seemed to be pathogenic, while an association between IgE autoantibodies and inflammatory BP phenotype was not indicated. PMID- 27716905 TI - The sociology of late secularization: social divisions and religiosity. AB - At the start of the twentieth century the religious differed from the religiously indifferent largely in being religious. Now they differ in a number of other social and demographic characteristics that reduce interaction between the two populations further than simple numbers would require. That some of the main carriers of religion are immigrants or adherents of recently imported faiths reinforces the sense that religion is what other people do. In the context of the stock of religious knowledge being depleted and religion-taken-too-seriously being unpopular, the narrow demographic base of the religious makes conversion unlikely and thus makes the reversal of secularization unlikely. PMID- 27716906 TI - Decreased level of interleukin-10-producing B cells in patients with pemphigus but not in patients with pemphigoid. AB - BACKGROUND: While the frequency of interleukin (IL)-10-producing B (B10) cells is reported to have an inverse correlation with disease activity in some human autoimmune diseases, the association between B10 cells and autoimmune blistering diseases (AIBD) has not been well evaluated. Although several phenotypes of human regulatory B cells have been proposed, the most appropriate one in AIBD has not been established. OBJECTIVE: To evaluate B10 cells in AIBD including their phenotypes. METHODS: Peripheral blood mononuclear cells were isolated from 39 patients with AIBD, including 14 with pemphigus and 25 with pemphigoid, and 10 healthy controls. We investigated the frequencies of B10 cells and CD19+ CD24hi CD38hi B cells using flow cytometry. RESULTS: The frequencies of B10 cells and CD19+ CD24hi CD38hi B cells were significantly lower and higher, respectively, in patients with pemphigus compared with healthy controls. Comparing patients with pemphigoid and healthy controls, no significant difference in the frequencies of B10 cells and CD19+ CD24hi CD38hi B cells was observed. B10-cell level in pemphigus was not associated with disease severity but inversely correlated with the required dose of steroid for treatment. While no significant difference in the frequency of IL-10-producing cells among CD19+ CD24hi CD38hi B cells was observed, in CD9+ and CD27- B-cell subsets it was significantly decreased in patients with pemphigus compared with healthy controls. CONCLUSIONS: Our results suggest the association of B10 cells with pemphigus but not with pemphigoid. The decrease in B10-cell level in pemphigus is partly caused by the lower production of IL-10 in CD9+ and CD27- B-cell subsets.

PMID- 27716908 TI - The Effects of Distance to Dentists and Dentist Supply on Children's Use of Dental Care. AB - OBJECTIVE: To examine the effects of distance to dentists and dentist supply on dental services use among children with Medicaid coverage in Iowa. DATA SOURCE: Iowa Medicaid claims for enrolled children between 2000 and 2009. STUDY DESIGN: The study sample included 41,554 children (providing 158,942 child-year observations) who were born in Iowa between 2000 and 2006 and enrolled from birth in the Iowa Medicaid program. Children were followed through 2009. We used logistic regression to simultaneously examine the effects of distance (miles to nearest dentist) and county-level dentist supply on a broad range of dental services controlling for key confounders. Additional models only used within child variation over time to remove unobservable time-invariant confounders. PRINCIPAL FINDINGS: Distance was related to lower utilization of comprehensive dental exams (2 percent lower odds per 1 mile increase in distance), an effect that also held in models using within-child variation only. Dentist supply was positively related to comprehensive exams and other preventive services and negatively related to major dental treatments; however, these associations became smaller and insignificant when examining within-child changes except for other preventive services. CONCLUSIONS: Longer distance to dentists is a barrier for use of comprehensive dental exams, conditional on dentist supply. PMID- 27716910 TI - The management of acne vulgaris in primary care: a cohort study of consulting and prescribing patterns using the Clinical Practice Research Datalink. AB - BACKGROUND: Effective management of acne vulgaris in primary care involves support (usually provided over a number of consultations) and prescription of effective treatments. However, consulting and prescribing patterns for acne in primary care are not well described. OBJECTIVES: To describe the rate of primary care consultations and follow-up consultations; prescribing patterns, including overall use of acne-related medications (ARMs); and initial and follow-up prescription for acne vulgaris in the U.K. METHODS: U.K. primary-care acne consultations and prescriptions for ARMs were identified in the Clinical Practice Research Datalink. Annual consultation rates (between 2004 and 2013) by age and sex, new consultations and consultations in the subsequent year were calculated, along with prescribing trends - during a new consultation and over the subsequent 90 days and year - using the number of registered patients as the denominator. RESULTS: Two-thirds (66.1%) of patients who had a new acne consultation had no further acne consultations in the subsequent year. Overall 26.7%, 24.9%, and 23.6% and 2.8% of patients were prescribed no ARM, an oral antibiotic, a topical antibiotic or an oral plus topical antibiotic, respectively, during a new acne consultation. In total 60.1% and 38.6% of patients prescribed an ARM received no further ARM prescriptions in the following 90 days and 1 year, respectively, despite most prescriptions being for 2 months or less. Prescribing rates for lymecycline and topical combined clindamycin and benzoyl peroxide increased substantially between 2004 and 2013. There were no important changes in consultation rates between 2004 and 2013. CONCLUSIONS: These data suggest that patients with acne are receiving a suboptimal initial choice of ARMs, longitudinal care and prescribing. PMID- 27716909 TI - Clarifying the biological significance of the CHK2 K373E somatic mutation discovered in The Cancer Genome Atlas database. AB - We identified CHK2 K373E as a recurrent mutation in The Cancer Genome Atlas (TCGA) database. In this study, we demonstrate that the K373E mutation disrupts CHK2 autophosphorylation as well as kinase activity, thus leading to impairment of CHK2 functions in suppressing cell proliferation and promoting cell survival after ionizing radiation. We propose that K373E impairs p53-independent induction of p21WAF1/CIP1 by CHK2. Our data implicate the K373E mutation of CHK2 in tumorigenesis. PMID- 27716911 TI - Understanding the Association Between Negative Life Events and Suicidal Risk in College Students: Examining Self-Compassion as a Potential Mediator. AB - OBJECTIVE: We tested a hypothesized model consistent with the notion that self compassion mediates the association between negative life events and suicidal risk (viz., depressive symptoms and suicidal behaviors) in college students METHOD: The sample was comprised of 331 college students. Self-compassion facets (viz., self-kindness, self-judgment, common humanity, isolation, mindfulness, and overidentification) were used in testing for multiple mediation, controlling for sex. RESULTS: Common humanity, mindfulness, and overidentification were found to mediate the association between negative life events (NLE) and depressive symptoms. However, common humanity was found to be the only mediator of the association between NLE and suicidal behaviors. CONCLUSION: These findings suggest that there are specific facets of self-compassion that account for the association between NLE and suicidal risk in college students and that (loss of) common humanity plays a central role in this process. PMID- 27716912 TI - Cancer incidence and cancer control in Mongolia: Results from the National Cancer Registry 2008-12. AB - Mongolia has a high burden from noncommunicable diseases, with cancer now the second leading cause of mortality. Given the paucity of situation analyses from the country, this study reports cancer data based on new cases 2008-12 from the National Cancer Registry of Mongolia covering the entire population (2.87 million). New cancer cases of 21,564 were diagnosed over the 5-year period, with a slight predominance of cases (52%) in men. Liver cancer was the leading cancer site in both sexes (ASRs of 114.7 and 74.6 per 100,000 males and females), and responsible for almost two-fifths of all cancer diagnoses, followed by cancers of stomach, lung and oesophagus in men and cervix, stomach and oesophagus in women. The cumulative risk of incidence for all cancers (27.7% and 20.8% in men and women, respectively) positions Mongolia above China (20.2% and 13.3%), below the United States (34.1% and 28.5%) and similar to Russia (26.1% and 19.1%). These figures shed light on the considerable magnitude of cancer in the country and the large fraction of cancers that can be prevented by lifestyle modifications and vaccine implementation. An expansion of activities of the cancer registry and the continued development of research are necessary steps in support of national cancer control planning in Mongolia. PMID- 27716913 TI - Relation between ultrasonic properties, rheology and baking quality for bread doughs of widely differing formulation. AB - BACKGROUND: The objective was to evaluate whether an ultrasonic reflectance technique has predictive capacity for breadmaking performance of doughs made under a wide range of formulation conditions. Two flours of contrasting dough strength augmented with different levels of ingredients (inulin, oil, emulsifier or salt) were used to produce different bread doughs with a wide range of properties. Breadmaking performance was evaluated by conventional large-strain rheological tests on the dough and by assessment of loaf quality. The ultrasound tests were performed with a broadband reflectance technique in the frequency range of 0.3-6 MHz. RESULTS: Principal component analysis showed that ultrasonic attenuation and phase velocity at frequencies between 0.3 and 3 MHz are good predictors for rheological and bread scoring characteristics. CONCLUSIONS: Ultrasonic parameters had predictive capacity for breadmaking performance for a wide range of dough formulations. Lower frequency attenuation coefficients correlated well with conventional quality indices of both the dough and the bread. (c) 2016 Society of Chemical Industry. PMID- 27716914 TI - Global antioxidant response of meat. AB - BACKGROUND: The global antioxidant response (GAR) method uses an enzymatic digestion to release antioxidants from foods. Owing to the importance of digestion for protein breakdown and subsequent release of bioactive compounds, the aim of the present study was to compare the GAR method for meat with the existing methodologies: the extraction-based method and QUENCHER. Seven fresh meats were analyzed using ABTS and FRAP assays. RESULTS: Our results indicated that the GAR of meat was higher than the total antioxidant capacity (TAC) assessed with the traditional extraction-based method. When evaluated with GAR, the thermal treatment led to an increase in the TAC of the soluble fraction, contrasting with a decreased TAC after cooking measured using the extraction based method. The effect of thermal treatment on the TAC assessed by the QUENCHER method seemed to be dependent on the assay applied, since results from ABTS differed from FRAP. CONCLUSION: Our results allow us to hypothesize that the activation of latent bioactive peptides along the gastrointestinal tract should be taken into consideration when evaluating the TAC of meat. Therefore, we conclude that the GAR method may be more appropriate for assessing the TAC of meat than the existing, most commonly used methods. (c) 2016 Society of Chemical Industry.

AB - OBJECTIVES/HYPOTHESIS: Complete pharyngoesophageal strictures may be encountered by the otolaryngologist as a consequence of radiation/chemoradiotherapy therapies for head and neck cancer. A combined anterograde and retrograde dilation procedure (rendezvous procedure) has proven to be a useful surgical intervention in these cases. We assess the long-term swallowing outcomes of this patient cohort including gastrostomy tube (G-tube) reliance, swallowing quality of life, and variables that contribute to improved swallowing outcomes. STUDY DESIGN: Retrospective chart review. METHODS: A retrospective chart review of 18 consecutive patients treated with rendezvous procedures between April 2007 and May 2015 was carried out. Data were collected from chart review and follow-up telephone calls including demographics, surgical/postoperative course details, and Eating Assessment Tool (EAT-10) (swallowing quality of life) scores. RESULTS: The completion rate of the procedure was 83% (15 completed/3 procedures aborted). Average follow-up was 22 months. Thirteen of 15 (86.7%) achieved an oral diet, and 7/15 (46.7%) had their G-tube removed. G-tube-independent (GTI) patients had an average stricture length of 2.33 cm and an average distance from the incisors of 17.4 cm compared to G-tube dependent-(GTD) patients who had an average stricture length of 2.63 cm and 14.6 cm mean distance from the incisors (P = .66 and .0343, respectively). Final EAT-10 scores averaged 20.1 in GTI patients and 33.8 in GTD patients (P = .022). Stricture/incisor distance and EAT-10 scores demonstrated a moderate to strong negative correlation (r = -0.67). CONCLUSIONS: Following the endoscopic rendezvous procedure, swallowing outcomes and G-tube status is related to the distance of the stricture from the incisors.

AB - OBJECTIVE: Visionary images are identity-relevant, picture-like mental representations of a desirable and attainable future appearing regularly in a person's stream of thought. Prior research indicates that both mental and real images provide access to implicit motives. We therefore proposed that visionary images motivate people by arousing their implicit motives and tested this hypothesis in two experimental studies. METHOD: We used guided visualizations to administer motive-domain-specific visionary images (Study 1: achievement and neutral, Mage = 24.4, 51 participants, 34 women; Study 2: affiliation and power, Mage = 24.01, 51 participants, 28 women) to arouse the respective implicit motive. Motivation was measured via residual changes in affective (i.e., changes in affective arousal), behavioral (i.e., performance on a concentration task, behavioral choices in a prisoner's dilemma), and mental (i.e., motive imagery in the Picture Story Exercise) indicators of motivation. RESULTS: The results largely confirmed our hypothesis. Visionary images increased motivation in the targeted domain. Some effects were moderated by participants' implicit motives. CONCLUSIONS: The findings underscore the role of implicit motives in understanding the motivational effectiveness of visionary images. PMID- 27716916 TI - Peroxisome proliferator-activated receptor-gamma coactivator 1 alpha1 induces a cardiac excitation-contraction coupling phenotype without metabolic remodelling. AB - KEY POINTS: Transcriptional co-activator PGC-1alpha1 has been shown to regulate energy metabolism and to mediate metabolic adaptations in pathological and physiological cardiac hypertrophy but other functional implications of PGC 1alpha1 expression are not known. Transgenic PGC-1alpha1 overexpression within the physiological range in mouse heart induces purposive changes in contractile properties, electrophysiology and calcium signalling but does not induce substantial metabolic remodelling. The phenotype of the PGC-1alpha1 transgenic mouse heart recapitulates most of the functional modifications usually associated with the exercise-induced heart phenotype, but does not protect the heart against load-induced pathological hypertrophy. Transcriptional effects of PGC-1alpha1 show clear dose-dependence with diverse changes in genes in circadian clock, heat shock, excitability, calcium signalling and contraction pathways at low overexpression levels, while metabolic genes are recruited at much higher PGC 1alpha1 expression levels. These results imply that the physiological role of PGC 1alpha1 is to promote a beneficial excitation-contraction coupling phenotype in the heart. ABSTRACT: The transcriptional coactivator PGC-1alpha1 has been identified as a central factor mediating metabolic adaptations of the heart. However, to what extent physiological changes in PGC-1alpha1 expression levels actually contribute to the functional adaptation of the heart is still mostly unresolved. The aim of this study was to characterize the transcriptional and functional effects of physiologically relevant, moderate PGC-1alpha1 expression in the heart. In vivo and ex vivo physiological analysis shows that expression of PGC-1alpha1 within a physiological range in mouse heart does not induce the expected metabolic alterations, but instead induces a unique excitation contraction (EC) coupling phenotype recapitulating features typically seen in physiological hypertrophy. Transcriptional screening of PGC-1alpha1 overexpressing mouse heart and myocyte cultures with higher, acute adenovirus induced PGC-1alpha1 expression, highlights PGC-1alpha1 as a transcriptional coactivator with a number of binding partners in various pathways (such as heat shock factors and the circadian clock) through which it acts as a pleiotropic transcriptional regulator in the heart, to both augment and repress the expression of its target genes in a dose-dependent fashion. At low levels of overexpression PGC-1alpha1 elicits a diverse transcriptional response altering the expression state of circadian clock, heat shock, excitability, calcium signalling and contraction pathways, while metabolic targets of PGC-1alpha1 are recruited at higher PGC-1alpha1 expression levels. Together these findings demonstrate that PGC-1alpha1 elicits a dual effect on cardiac transcription and phenotype. Further, our results imply that the physiological role of PGC-1alpha1 is to promote a beneficial EC coupling phenotype in the heart. PMID- 27716918 TI - Commode Cardia-Death by Valsalva Maneuver: A Case Series. AB - The Valsalva maneuver is used in clinical medicine for the diagnosis and/or treatment of various cardiovascular conditions. It can also be used in activities of daily living, such as defecation. Due to the cardiovascular effects produced during the Valsalva maneuver, it may be contraindicated in certain medical conditions and could be a trigger of sudden cardiac death. The incidence and prevalence of death following Valsalva maneuver in the presence of underlying cardiovascular disease, or "commode cardia," has not been examined. In 2012, the Wayne County Medical Examiner's Office (Detroit, MI) investigated 21 deaths that occurred on the toilet, fourteen of which were due to cardiovascular disease. In another 31 deaths in the bathroom due to cardiovascular disease, the possibility that the decedent defecated immediately prior to death could not be excluded. Hence, the incidence of commode cardia in this population ranges from 2.3 to 7.4% of all cardiovascular-related deaths. PMID- 27716919 TI - Intensive Treatment of Pediatric OCD: The Case of Sarah. AB - While cognitive behavior therapy (CBT) either alone or in combination with pharmacotherapy (e.g., selective serotonin reuptake inhibitor) has received strong empirical support for obsessive-compulsive disorder (OCD; Geller & March, 2012), this treatment is often inaccessible for children and their families. Barriers to accessing CBT include a lack of trained therapists, clinician and patient beliefs about CBT, and geographical and financial barriers (Goisman et al., 1993; Marques et al., 2010; Turner, Heyman, Futh, & Lovell, 2009). Furthermore, while the majority of therapists endorse a CBT orientation, exposure therapy is rarely used in routine clinical practice (Whiteside, Deacon, Benito, & Stewart, 2016). This case study therefore describes an intensive 2- or 3-session treatment of childhood OCD (e.g., Farrell et al., 2016) to improve efficient and rapid delivery of evidence-based treatment. The case of Sarah illustrates this intensive treatment model and highlights clinical considerations for therapists when delivery a concentrated, time-limited treatment. PMID- 27716920 TI - Modified Cognitive Behavior Therapy for Severe, Treatment-Resistant Obsessive Compulsive Disorder in an Adolescent With Autism Spectrum Disorder. AB - There is a high rate of comorbidity between obsessive-compulsive disorder (OCD) and autism spectrum disorders (ASD). Standard cognitive-behavior therapy (CBT) protocols have been shown to be less effective in treating OCD in young people with ASD than in typically developing youth. This case study describes the treatment of an adolescent boy with severe, treatment-resistant OCD and ASD using a modified CBT approach. Modifications to a standard evidence-based CBT for OCD protocol included extended psychoeducation about anxiety; regular home-based sessions; and increased involvement of systems, including family and school. Multi-informant outcome data indicated significant improvements in OCD symptoms over the course of treatment with gains being maintained over a 12-month follow up period. These findings demonstrate the potential efficacy of modified CBT for pediatric OCD in the context of ASD. PMID- 27716921 TI - Life Events and Personality Trait Change. AB - OBJECTIVE: Theory and research have emphasized the impact of life events on personality trait change. In this article, we review prospective research on personality trait change in response to nine major life events in the broader domains of love and work. METHOD: We expected to find that life events lead to personality trait change to the extent that they have a lasting influence on individuals' thoughts, feelings, and behavior. Moreover, we predicted that love related life events such as marriage or parenthood would be more strongly related to changes in traits that emphasize affective content, whereas work-related life events would be more likely to lead to change in traits that reflect behavioral or cognitive content. RESULTS: The current state of research provided some evidence that life events can lead to changes in personality traits and that different life events may be differently related to specific trait domains. CONCLUSIONS: A more general conclusion emerging from this review is that the evidence for the nature, shape, and timing of personality trait change in response to life events is still preliminary. We discuss the implications of the results for theory and research and provide directions for future studies on life events and personality trait change. PMID- 27716922 TI - Coalescing red algae exhibit noninvasive, reversible chimerism. AB - Chimerism is produced by the somatic fusion of two or more genetically distinct conspecific individuals. In animals, the main cost of fusion is competition between genetically different cell lineages and the probability of original cell line replacement by more competitive invasive lines, which limits its natural frequency (3%-5%). In red and brown seaweeds, chimerism is widespread (27%-53%), seemingly without the negative outcomes described for animals. The rigidity of cell walls in macroalgae prevents cell motility and invasions. In addition, in moving waters, most somatic fusions involve the holdfast. Histological observations in laboratory-built bicolor macroalgal chimeras indicated that upright axes emerge from the base of plants by proliferation and vertical growth of discrete cell groups that include one or just a few of the cell lineages occurring in the holdfasts. Laboratory experiments showed growth competition between cell lineages, thus explaining lineage segregation during growth along originally chimeric erect axes. Genotyping of the axes showed more heterogeneous tissues basally, but apically more homogeneous ones, generating a vertical gradient of allele abundance and diversity. The few chimeric primary branches produced, eventually became homogenous after repeated branching. Therefore, coalescing macroagae exhibit a unique pattern of post-fusion growth, with the capacity to reverse chimerism. This pattern is significantly different from those in animals and land plants, suggesting chimerism is a biologically heterogeneous concept. PMID- 27716923 TI - Depth and temperature associations of haddock Melanogrammus aeglefinus off southern Newfoundland. AB - Using data collected as part of offshore surveys conducted during 1972-2013, haddock Melanogrammus aeglefinus association patterns with depth and temperature in southern Newfoundland waters, the northern extremity of the species' range in the western Atlantic Ocean, were quantified. They were typically concentrated in the deep warm waters along the narrow shelf slope in North-west Atlantic Fisheries Organization Divisions 3O and 3P with individuals moving seasonally into the shallow waters of the banks as they warmed. While M. aeglefinus were found over a range of depths and temperatures, they were primarily located at depths deeper and temperatures warmer than the median sampled. Analyses demonstrated that of the two hydrographic variables assessed, temperature was most influential in structuring distribution, with individuals appearing to change depth in order to maintain similar temperature throughout the year. Melanogrammus aeglefinus were found predominantly in temperatures of c. 4-8 degrees C which often represented some of the warmest waters available. Differences in fish-habitat association patterns in relation to sex or maturity status were not readily apparent from the analyses. Warming conditions off Newfoundland and Labrador in recent years might be predicted to improve local M. aeglefinus productivity. PMID- 27716924 TI - Electrophysiological activity of the pharyngoesophageal transition of total laryngectomees. AB - OBJECTIVES/HYPOTHESIS: To determine the association of the electrophysiological activity of the pharyngoesophageal transition with tracheoesophageal speech proficiency in total laryngectomees. STUDY DESIGN: An observational (nonexperimental) study of the correlation type with a descriptive approach. METHODS: Thirty-four individuals (26 males), average age 62.5 years, total laryngectomees rehabilitated with the use of a tracheoesophageal prosthesis, were assessed for tracheoesophageal speech proficiency using an adapted protocol and classified as good, moderate, or poor speakers. Next they were submitted to electromyography of the muscles of the pharyngoesophageal transition with a needle electrode. The area to be examined was located by videofluoroscopy. Electromyographic analysis was characterized as normal, neurogenic injury (moderate to severe, severe, severe to total), myopathic injury, or inconclusive. The Fisher exact test was used to determine the association between the speech proficiency variables and electromyography. RESULTS: in the final rating of tracheoesophageal speech proficiency, most laryngectomees were categorized as moderate (n = 24) and a few as good (n = 3). Electromyography revealed neurogenic injury in all laryngectomees, which was severe in most cases (n = 20), followed by severe to total (n = 10), and moderate to severe injury (n = 4). There was no significant association between he electromyographic analyses of neurogenic injuries and tracheoesophageal speech proficiency. CONCLUSIONS: Whether or not the musculature of the pharyngoesophageal transition of tracheoesophageal speakers had a preserved motor unit, did not prevent voice acquisition and was not associated with tracheoesophageal speech proficiency. However, further studies are needed in this area. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:1369 1375, 2017. PMID- 27716925 TI - Auditory brainstem implant program development. AB - OBJECTIVE: Auditory brainstem implants (ABIs), which have previously been used to restore auditory perception to deaf patients with neurofibromatosis type 2 (NF2), are now being utilized in other situations, including treatment of congenitally deaf children with cochlear malformations or cochlear nerve deficiencies. Concurrent with this expansion of indications, the number of centers placing and expressing interest in placing ABIs has proliferated. Because ABI placement involves posterior fossa craniotomy in order to access the site of implantation on the cochlear nucleus complex of the brainstem and is not without significant risk, we aim to highlight issues important in developing and maintaining successful ABI programs that would be in the best interests of patients. DATA SOURCES: Especially with pediatric patients, the ultimate benefits of implantation will be known only after years of growth and development. These benefits have yet to be fully elucidated and continue to be an area of controversy. The limited number of publications in this area were reviewed. REVIEW METHODS: Review of the current literature was performed. RESULTS: Disease processes, risk/benefit analyses, degrees of evidence, and U.S. Food and Drug Administration approvals differ among various categories of patients in whom auditory brainstem implantation could be considered for use. CONCLUSION: We suggest sets of criteria necessary for the development of successful and sustaining ABI programs, including programs for NF2 patients, postlingually deafened adult nonneurofibromatosis type 2 patients, and congenitally deaf pediatric patients.

PMID- 27716926 TI - Comparison of quartz crystallographic preferred orientations identified with optical fabric analysis, electron backscatter and neutron diffraction techniques. AB - Three techniques are used to measure crystallographic preferred orientations (CPO) in a naturally deformed quartz mylonite: transmitted light cross-polarized microscopy using an automated fabric analyser, electron backscatter diffraction (EBSD) and neutron diffraction. Pole figure densities attributable to crystal plastic deformation are variably recognizable across the techniques, particularly between fabric analyser and diffraction instruments. Although fabric analyser techniques offer rapid acquisition with minimal sample preparation, difficulties may exist when gathering orientation data parallel with the incident beam. Overall, we have found that EBSD and fabric analyser techniques are best suited for studying CPO distributions at the grain scale, where individual orientations can be linked to their source grain or nearest neighbours. Neutron diffraction serves as the best qualitative and quantitative means of estimating the bulk CPO, due to its three-dimensional data acquisition, greater sample area coverage, and larger sample size. However, a number of sampling methods can be applied to FA and EBSD data to make similar approximations. PMID- 27716927 TI - Genetics of Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome. AB - Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome, also referred to as Mullerian agenesis, is the second most common cause of primary amenorrhea. It is characterized by congenital absence of the uterus, cervix, and the upper part of the vagina in otherwise phenotypically normal 46,XX females. MRKH syndrome has an incidence of about 1 in 4,500-5,000 newborn females and it is generally divided into two subtypes: MRKH type 1, in which only the upper vagina, cervix and the uterus are affected, and MRKH type 2, which is associated with additional malformations generally affecting the renal and skeletal systems, and also includes MURCS (MUllerian Renal Cervical Somite) characterized by cervico thoracic defects. MRKH syndrome is mainly sporadic; however, familial cases have been described indicating that, at least in a subset of patients, MRKH may be an inherited disorder. The syndrome appears to demonstrate an autosomal dominant inheritance pattern, with incomplete penetrance and variable expressivity. The etiology of MRKH syndrome is still largely unknown, probably because of its intrinsic heterogeneity. Several candidate causative genes have been investigated, but to date only WNT4 has been associated with MRKH with hyperandrogenism. This review summarizes and discusses the clinical features and details progress to date in understanding the genetics of MRKH syndrome. PMID- 27716928 TI - Direct and indirect influence of sulfur availability on phytoplankton evolutionary trajectories. AB - The sulfate facilitation hypothesis suggests that changes in ocean sulfate concentration influenced the rise to dominance of phytoplankton species of the red lineage. The mechanistic reasons for this phenomenon are not yet understood. We started to address this question by investigating the differences in S utilization by algae of the green and red lineages and in cyanobacteria cultured in the presence of either 5 mmol . L-1 (approximately equivalent to Paleozoic ocean concentrations) or 30 mmol . L-1 (corresponding to post-Mesozoic/extant concentrations) sulfate. The activities of the main enzymes involved in SO42- assimilation changed in response to changes in growth sulfate concentration. ATP sulfurylase showed different kinetics in the various taxa, with an especially odd behavior for the dinoflagellate. Sulfate availability had a modest effect on cell organic composition. Species-specific differences in the use of some elements were instead obvious in algae grown in the presence of different sulfate concentrations, overall confirming that algae of the red lineage do better at high sulfate than algae of the green lineage. The increase in sulfate concentration may thus have had an impact on phytoplankton radiation both through changes in their enzymatic machinery and through indirect repercussion on elemental usage. PMID- 27716929 TI - RSL class I genes positively regulate root hair development in Oryza sativa. AB - Root hairs are filamentous protuberances from superficial cells of plant roots that are critical for nutrient uptake. Genes encoding ROOT HAIR DEFECTIVE-SIX LIKE (RSL) class I basic helix-loop-helix proteins are expressed in future root hair cells (trichoblasts) of the Arabidopsis thaliana root where they positively regulate root hair cell development. We characterized the function of class I genes in Oryza sativa root development. We show that there are three RSL class I genes in O. sativa and that each is expressed in developing root hair cells. Reduction of RSL class I function results in the development of shorter root hairs than in wild-type. Ectopic overexpression results in the development of ectopic root hair cells. These data suggest that expression of individual RSL class I proteins is sufficient for root hair development in the cereal O. sativa (rice). Therefore RSL class I genes have been conserved since O. sativa and A. thaliana last shared a common ancestor. However, given that RSL class I genes are not sufficient for root hair development in A. thaliana, it suggests that there are differences in the mechanisms repressing RSL class I gene activity between members of the Poaceae and Brassicaceae. PMID- 27716931 TI - Compositional mapping of bitumen using local electrostatic force interactions in atomic force microscopy. AB - In recent years, many researchers have investigated bitumen surface morphology, especially the so-called bee-like structures, in an attempt to relate the chemical composition and molecular conformation to bitumen micromechanics and ultimately performance properties. Even though recent studies related surface morphology and its evolution to stiffness and stress localization, the complex chemical nature of bitumen and its time- and temperature-dependent properties still engender significant questions about the nature and origin of the observed morphological features and how they evolve due to exposure to various environmental and loading conditions. One such question is whether the observed surface features are formed from wax or from the coprecipitation of wax and asphaltene. Our prior work was mainly theoretical; it used density functional theory and showed that the coprecipitation theory may not stand, mainly because wax-asphaltene interactions are not thermodynamically favourable compared to wax wax interactions. This paper presents a comprehensive approach based on experiments to study surface morphology of bitumen and conduct compositional mapping to shed light on the origin of the bee-like surface morphological features. We used Atomic Force Microscopy (AFM), with the main focus being on single-pass detection and mapping of local electric properties, as a novel approach to enhance existing compositional mapping techniques. This method was found to be highly effective in differentiating various domains with respect to their polarity. The results of our study favour the hypothesis that the bee-like features are mainly composed of wax, including a variety of alkanes. PMID- 27716930 TI - Self-reported historic human immunodeficiency virus (HIV) testing in a Brazilian blood donor HIV case-control study. AB - BACKGROUND: There has been increased worldwide emphasis on the many benefits of human immunodeficiency virus (HIV) serostatus awareness for both infection prevention and improved treatment outcomes. Previous studies indicate that donors may use blood donation to be tested; the objectives of this analysis were to assess, among donors with previously undisclosed risk behavior in the 12 months before donation, the frequency of those who have previously been tested for HIV and the demographic and behavioral factors associated with such testing. STUDY DESIGN AND METHODS: In this secondary analysis from an HIV case-control study of blood donors in Brazil, we analyzed the response to the question, "Other than blood donation, have you ever been tested for HIV?" Demographic and disclosed risk behaviors associated with previous testing were determined. RESULTS: The study included 341 HIV-positive cases and 791 HIV-negative controls (1:2 case/control ratio). Overall, 31% of blood donors (40% of cases and 26% of controls) reported having been tested for HIV outside of blood donation. History of HIV testing varied according to sex, HIV status, and reported sexual risk behavior. CONCLUSION: Although it is encouraging that previous testing was more frequent in donors with acknowledged sexual risk behavior in Brazil, 60% still had not been tested for HIV outside of the blood donation setting. Educating donors on the importance of not using blood centers as a means to get tested for HIV in Brazil, especially if they engage in higher risk behaviors, and seeking alternate testing venues instead could improve the safety of donated blood. PMID- 27716932 TI - Bayley-III: Cultural differences and language scale validity in a Danish sample. AB - The purpose of this study was to investigate cultural differences between Danish and American children at 2 and 3 years as measured with the developmental test Bayley-III, and to investigate the Bayley-III Language Scale validity. The Danish children (N = 43) were tested with the Bayley-III and their parents completed an additional language questionnaire (the MacArthur-Bates CDI). Results showed that scores from the Danish children did not differ significantly from the American norms on the Cognitive or Motor Scale, but the Danish sample scored significantly higher on the Language Scale. A comparison of the Bayley-III Language subtests with the CDI showed that the two measures correlated significantly, but the percentile score from the CDI was significantly higher than the percentile score from the Bayley-III Language subtests. This could be because the two instruments measure slightly different areas of language development, or because the Bayley III overestimates language development in Danish children. However, due to the limitations of the current study, further research is needed to clarify this issue. PMID- 27716933 TI - Solanum tuberosum StCDPK1 is regulated by miR390 at the posttranscriptional level and phosphorylates the auxin efflux carrier StPIN4 in vitro, a potential downstream target in potato development. AB - Among many factors that regulate potato tuberization, calcium and calcium dependent protein kinases (CDPKs) play an important role. CDPK activity increases at the onset of tuber formation with StCDPK1 expression being strongly induced in swollen stolons. However, not much is known about the transcriptional and posttranscriptional regulation of StCDPK1 or its downstream targets in potato development. To elucidate further, we analyzed its expression in different tissues and stages of the life cycle. Histochemical analysis of StCDPK1::GUS (beta-glucuronidase) plants demonstrated that StCDPK1 is strongly associated with the vascular system in stems, roots, during stolon to tuber transition, and in tuber sprouts. In agreement with the observed GUS profile, we found specific cis acting elements in StCDPK1 promoter. In silico analysis predicted miR390 to be a putative posttranscriptional regulator of StCDPK1. Quantitative real time polymerase chain reaction (qRT-PCR) analysis showed ubiquitous expression of StCDPK1 in different tissues which correlated well with Western blot data except in leaves. On the contrary, miR390 expression exhibited an inverse pattern in leaves and tuber eyes suggesting a possible regulation of StCDPK1 by miR390. This was further confirmed by Agrobacterium co-infiltration assays. In addition, in vitro assays showed that recombinant StCDPK1-6xHis was able to phosphorylate the hydrophilic loop of the auxin efflux carrier StPIN4. Altogether, these results indicate that StCDPK1 expression is varied in a tissue-specific manner having significant expression in vasculature and in tuber eyes; is regulated by miR390 at posttranscriptional level and suggest that StPIN4 could be one of its downstream targets revealing the overall role of this kinase in potato development.

PMID- 27716935 TI - Connecting the plant vasculature to friend or foe. AB - Contents 1611 I. 1611 II. 1612 III. 1612 IV. 1614 V. 1614 VI. 1614 VII. 1615 VIII. 1616 1616 References 1616 SUMMARY: The plant vasculature transports water, sugars, hormones, RNAs and proteins. Such critical functions need to be protected from attack by pests and pathogens or from damage by wounding. Plants have developed mechanisms to repair vasculature when such protections fail and to even initiate new vascular connections to tissues supporting symbionts. The developmental phenomena underlying vascular repair and rewiring are therefore critical for horticultural grafting, for plant infection and for mutualist associations with rhizosphere microbes. Despite the biological and economic interest, we are only beginning to understand how plants connect and reconnect their vasculature to a wide variety of organisms. Here, I discuss recent work and future prospects for this emerging field. PMID- 27716937 TI - Low levels of strigolactones in roots as a component of the systemic signal of drought stress in tomato. AB - Strigolactones (SL) contribute to drought acclimatization in shoots, because SL depleted plants are hypersensitive to drought due to stomatal hyposensitivity to abscisic acid (ABA). However, under drought, SL biosynthesis is repressed in roots, suggesting organ specificity in their metabolism and role. Because SL can be transported acropetally, such a drop may also affect shoots, as a systemic indication of stress. We investigated this hypothesis by analysing molecularly and physiologically wild-type (WT) tomato (Solanum lycopersicum) scions grafted onto SL-depleted rootstocks, compared with self-grafted WT and SL-depleted genotypes, during a drought time-course. Shoots receiving few SL from the roots behaved as if under mild stress even if irrigated. Their stomata were hypersensitive to ABA (likely via a localized enhancement of SL synthesis in shoots). Exogenous SL also enhanced stomata sensitivity to ABA. As the partial shift of SL synthesis from roots to shoots mimics what happens under drought, a reduction of root-produced SL might represent a systemic signal unlinked from shootward ABA translocation, and sufficient to prime the plant for better stress avoidance. PMID- 27716936 TI - Integration of light and circadian signals that regulate chloroplast transcription by a nuclear-encoded sigma factor. AB - We investigated the signalling pathways that regulate chloroplast transcription in response to environmental signals. One mechanism controlling plastid transcription involves nuclear-encoded sigma subunits of plastid-encoded plastid RNA polymerase. Transcripts encoding the sigma factor SIG5 are regulated by light and the circadian clock. However, the extent to which a chloroplast target of SIG5 is regulated by light-induced changes in SIG5 expression is unknown. Moreover, the photoreceptor signalling pathways underlying the circadian regulation of chloroplast transcription by SIG5 are unidentified. We monitored the regulation of chloroplast transcription in photoreceptor and sigma factor mutants under controlled light regimes in Arabidopsis thaliana. We established that a chloroplast transcriptional response to light intensity was mediated by SIG5; a chloroplast transcriptional response to the relative proportions of red and far red light was regulated by SIG5 through phytochrome and photosynthetic signals; and the circadian regulation of chloroplast transcription by SIG5 was predominantly dependent on blue light and cryptochrome. Our experiments reveal the extensive integration of signals concerning the light environment by a single sigma factor to regulate chloroplast transcription. This may originate from an evolutionarily ancient mechanism that protects photosynthetic bacteria from high light stress, which subsequently became integrated with higher plant phototransduction networks. PMID- 27716938 TI - Nanostructured Polymeric Micelles Carrying Xanthene Dyes for Photodynamic Evaluation. AB - It was evaluated the properties of the xanthene dyes Erythrosin B, Eosin Y and theirs Methyl, Butyl and Decyl ester derivatives as possible photosensitizers (PS) for photodynamic treatments. The more hydrophobic dyes self-aggregate in water/ethanol solutions above 70% water (vol/vol) in the mixture. In buffered water, these PS were encapsulated in Pluronic polymeric surfactants of P-123 and F-127 by two methodologies: direct addition and the thin-film solid dispersion methods. The thin-film solid method provided formulations with higher stabilities besides effective encapsulation of the PS as monomers. Size measurements demonstrated that Pluronic forms self-assembled micelles with uniform size, which present slightly negative surface potential and a spherical form detected by TEM microscopy. The ester length modulates xanthene localization in the micelle, which is deeper with the increase in the alkyl chain. Moreover, some PS are distributed into two populations: one on the corona micelle interface shell (PEO layer) and the other into the core (PPO region). Although all PS formulations show high singlet oxygen quantum yield, promising results were obtained for Erythrosin B esters with the hydrophobic P-123, which ensures their potential as drug for clinical photodynamic applications. PMID- 27716939 TI - Tibetan Firefly Luciferase with Low Temperature Adaptation. AB - Fireflies are widespread all over the world and a numerous numbers of luciferases have been isolated and characterized. In this study, we identified and characterized the luciferase and luciferase-like genes from a Tibetan firefly collected in Shangri-La, China. The altitude of this area is more than 3300 m. We saw this Tibetan firefly flying with strong luminescence after sunset at ~10 degrees C. We analyzed the transcriptome of Tibetan firefly using head, thorax, abdomen (without light organ), and light organ tissue by RNA sequencing. We identified one luciferase gene, which was almost identical to luciferase from fireflies Pyrocoelia species, and expressed specifically in the light organ. Interestingly, the optimal temperature of the Tibetan firefly recombinant luciferase was 10 degrees C. The Km for D-luciferin and ATP of the recombinant luciferase was 23 and 154 MUm, respectively. The optimal pH was around 7.0-7.5. The emission peak was 556 nm at pH 8.0, while it shifted to 606 nm at pH 6.0. We also found a luciferase-like gene with 43% identical amino acids to the Tibetan firefly luciferase, which was scarcely expressed in any portion of the adult body. No luciferase activity was detected for this luciferase-like protein. PMID- 27716940 TI - Dark-induced leaf senescence: new insights into a complex light-dependent regulatory pathway. AB - 563 I. 563 II. 564 III. 564 IV. 565 V. 565 VI. 567 VII. 567 568 References 568 SUMMARY: Leaf senescence - the coordinated, active process leading to the organized dismantling of cellular components to remobilize resources - is a fundamental aspect of plant life. Its tight regulation is essential for plant fitness and has crucial implications for the optimization of plant productivity and storage properties. Various investigations have shown light deprivation and light perception via phytochromes as key elements modulating senescence. However, the signalling pathways linking light deprivation and actual senescence processes have long remained obscure. Recent analyses have demonstrated that PHYTOCHROME INTERACTING FACTORS (PIFs) are major transcription factors orchestrating dark induced senescence (DIS) by targeting chloroplast maintenance, chlorophyll metabolism, hormone signalling and production, and the expression of senescence master regulators, uncovering potential molecular links to the energy deprivation signalling pathway. PIF-dependent feed-forward regulatory modules might be of critical importance for the highly complex and initially light-reversible DIS induction. PMID- 27716941 TI - Photobiomodulation by Infrared Diode Laser: Effects on Intracellular Calcium Concentration and Nitric Oxide Production of Paramecium. AB - In Paramecium, cilia beating is correlated to intracellular calcium concentration ([Ca2+ ]i) and nitric oxide (NO) synthesis. Recent findings affirm that photobiomodulation (PBM) can transiently increase the [Ca2+ ]i in mammalian cells. In this study, we investigated the effect of both 808 and 980 nm diode laser irradiated with flat-top hand-piece on [Ca2+ ]i and NO production of Paramecium primaurelia, to provide basic information for the development of new therapeutic approaches. In the experiments, the laser power in CW varied (0.1; 0.5; 1; and 1.5 W) to generate the following respective fluences: 6.4; 32; 64; and 96 J cm-2 . The 6.4 J cm-2 did not induce PBM if irradiated by both 808 and 980 nm diode laser. Conversely, the 32 J cm-2 fluence had no effect on Paramecium cells if irradiated by the 808 nm laser, while if irradiated by the 980 nm laser induced increment in swimming speed (suggesting an effect on the [Ca2+ ]i, NO production, similar to the 64 J cm-2 with the 808 nm wavelength). The more evident discordance occurred with the 96 J cm-2 fluence, which had the more efficient effect on PBM among the parameters if irradiated with the 808 nm laser and killed the Paramecium cells if irradiated by the 980 nm laser. Lastly, the 980 nm and 64 or 96 J cm-2 were the only parameters to induce a release of stored calcium. PMID- 27716942 TI - An assay for entry of secreted fungal effectors into plant cells. AB - Successful colonization of plants by prokaryotic and eukaryotic pathogens requires active effector-mediated suppression of defense responses and host tissue reprogramming. Secreted effector proteins can either display their activity in the apoplast or translocate into host cells and function therein. Although characterized in bacteria, the molecular mechanisms of effector delivery by fungal phytopathogens remain elusive. Here we report the establishment of an assay that is based on biotinylation of effectors in the host cytoplasm as hallmark of uptake. The assay exploits the ability of the bacterial biotin ligase BirA to biotinylate any protein that carries a short peptide (Avitag). It is based on the stable expression of BirA in the cytoplasm of maize plants and on engineering of Ustilago maydis strains to secrete Avitagged effectors. We demonstrate translocation of a number of effectors in the U. maydis-maize system and show data that suggest that the uptake mechanism could be rather nonspecific The assay promises to be a powerful tool for the classification of effectors as well as for the functional study of effector uptake mechanism not only in the chosen system but more generally for systems where biotrophic interactions are established. PMID- 27716943 TI - Paracetamol (acetaminophen) for prevention or treatment of pain in newborns. AB - BACKGROUND: Newborn infants have the ability to experience pain. Hospitalised infants are exposed to numerous painful procedures. Healthy newborns are exposed to pain if the birth process consists of assisted vaginal birth by vacuum extraction or by forceps and during blood sampling for newborn screening tests. OBJECTIVES: To determine the efficacy and safety of paracetamol for the prevention or treatment of procedural/postoperative pain or pain associated with clinical conditions in neonates. To review the effects of various doses and routes of administration (enteral, intravenous or rectal) of paracetamol for the prevention or treatment of pain in neonates. SEARCH METHODS: We used the standard search strategy of the Cochrane Neonatal Review group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 4), MEDLINE via PubMed (1966 to 9 May 2016), Embase (1980 to 9 May 2016), and CINAHL (1982 to 9 May 2016). We searched clinical trials' databases, Google Scholar, conference proceedings, and the reference lists of retrieved articles. SELECTION CRITERIA: We included randomised and quasi-randomised controlled trials of paracetamol for the prevention/treatment of pain in neonates (<= 28 days of age). DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data from the articles using pre-designed forms. We used this form to decide trial inclusion/exclusion, to extract data from eligible trials and to request additional published information from authors of the original reports. We entered and cross-checked data using RevMan 5 software. When noted, we resolved differences by mutual discussion and consensus. We used the GRADE approach to assess the quality of evidence. MAIN RESULTS: We included nine trials with low risk of bias, which assessed paracetamol for the treatment of pain in 728 infants. Painful procedures studied included heel lance, assisted vaginal birth, eye examination for retinopathy of prematurity assessment and postoperative care. Results of individual studies could not be combined in meta-analyses as the painful conditions, the use of paracetamol and comparison interventions and the outcome measures differed. Paracetamol compared with water, cherry elixir or EMLA cream (eutectic mixture of lidocaine and prilocaine) did not significantly reduce pain following heel lance. The Premature Infant Pain Profile score (PIPP) within three minutes following lancing was higher in the paracetamol group than in the oral glucose group (mean difference (MD) 2.21, 95% confidence interval (CI) 0.72 to 3.70; one study, 38 infants). Paracetamol did not reduce "modified facies scores" after assisted vaginal birth (one study, 119 infants). In another study (n = 123), the Echelle de Douleur et d'Inconfort du Nouveau-Ne score at two hours of age was significantly higher in the group that received paracetamol suppositories than in the placebo suppositories group (MD 1.00, 95% CI 0.60 to 1.40). In that study, when infants were subjected to a heel lance at two to three days of age, Bernese Pain Scale for Neonates scores were higher in the paracetamol group than in the placebo group, and infants spent a longer time crying (MD 19 seconds, 95% CI 14 to 24). For eye examinations, no significant reduction in PIPP scores in the first or last 45 seconds of eye examination was reported, nor at five minutes after the eye examination. In one study (n = 81), the PIPP score was significantly higher in the paracetamol group than in the 24% sucrose group (MD 3.90, 95% CI 2.92 to 4.88). In one study (n = 114) the PIPP score during eye examination was significantly lower in the paracetamol group than in the water group (MD -2.70, 95% CI -3.55 to 1.85). For postoperative care following major surgery, the total amount of morphine (ug/kg) administered over 48 hours was significantly less among infants assigned to the paracetamol group than to the morphine group (MD -157 ug/kg, 95% CI -27 to -288). No adverse events were noted in any study. The quality of evidence according to GRADE was low. AUTHORS' CONCLUSIONS: The paucity and low quality of existing data do not provide sufficient evidence to establish the role of paracetamol in reducing the effects of painful procedures in neonates. Paracetamol given after assisted vaginal birth may increase the response to later painful exposures. Paracetamol may reduce the total need for morphine following major surgery, and for this aspect of paracetamol use, further research is needed. PMID- 27716944 TI - MdMyb93 is a regulator of suberin deposition in russeted apple fruit skins. AB - A comparison of the transcriptomes of russeted vs nonrusseted apple skins previously highlighted a tight relationship between a gene encoding an MYB-type transcription factor, MdMYB93, and some key suberin biosynthetic genes. The present work assesses the role of this transcription factor in the suberization process. A phylogenetic analysis of MdMYB93 and Arabidopsis thaliana MYBs was performed and the function of MdMYB93 was further investigated using Agrobacterium-mediated transient overexpression in Nicotiana benthamiana leaves. An RNA-Seq analysis was performed to highlight the MdMYB93-regulated genes. Ultraperformance liquid chromatography-triple time-of-flight (UPLC-TripleTOF) and GC-MS were used to investigate alterations in phenylpropanoid, soluble-free lipid and lipid polyester contents. A massive accumulation of suberin and its biosynthetic precursors in MdMYB93 agroinfiltrated leaves was accompanied by a remobilization of phenylpropanoids and an increased amount of lignin precursors. Gene expression profiling displayed a concomitant alteration of lipid and phenylpropanoid metabolism, cell wall development, and extracellular transport, with a large number of induced transcripts predicted to be involved in suberin deposition. The present work supports a major role of MdMYB93 in the regulation of suberin deposition in russeted apple skins, from the synthesis of monomeric precursors, their transport, polymerization, and final deposition as suberin in primary cell wall. PMID- 27716945 TI - The effects of animal age, feeding regime and a dietary beta-agonist on tenderness of three beef muscles. AB - BACKGROUND: Animal age as determined by number of permanent incisors (p. i.) is used in classification of beef carcasses to describe expected meat tenderness. However, animals differing in age are reared under different production systems (pasture or feedlot). In addition to age, other factors associated with particular production systems may also influence the palatability of meat. Therefore, the effects of age combined with feeding regime and the supplementation of a beta-agonist (zilpaterol) on the tenderness of M. longissimus lumborum (LL), M. semitendinosus (ST) and M. biceps femoris (BF) muscles were investigated. RESULTS: Tenderness of LL cuts was least affected by age but zilpaterol significantly decreased tenderness and ageing potential. Tenderness of high-collagen cuts (BF and ST) was negatively affected by age due to reduced collagen solubility. The effect of zilpaterol on these cuts was less significant and BF and ST cuts of the grain-fed A-age animals (0 p. i.) supplemented with zilpaterol (AZ) were more tender than the same cuts of grass fed animals with 1-2 p. i. (AB-age) and grass-fed animals with 3-6 p. i. (B-age) according to Warner-Bratzler shear force (WBSF) and sensory analysis for tenderness. CONCLUSION: This study indicates that beta-agonists may influence variation in tenderness within an age class more than age or feeding regime. (c) 2016 Society of Chemical Industry. PMID- 27716946 TI - New opportunities and challenges in the assessment of drugs for atopic diseases. AB - Atopic conditions (atopic dermatitis, rhinitis, and asthma) belong to the most common noncommunicable diseases and are driven by chronic inflammatory reactions. They have a strong impact on the quality of life and represent a substantial and growing socio-economic burden. Interestingly, there is an increasing interest in the development of new therapeutic options with a number of biologics and small molecules targeting potential key mechanisms in atopic conditions. However, besides the safety issue, most of the new active substances are still evaluated according to the traditional efficacy paradigm focusing on the success in treating exacerbations and flares. Instead, the future approaches in drug development and assessment should rather concentrate on the long-term control of these diseases and consider their potential as disease-modifying strategies in the era of precision medicine. To reach this goal, a number of unsolved issues have to be addressed and consensually accepted by the stakeholders in this field. Thus, a successful and rapid development of new treatments requests a paradigm shift and a new way of thinking in the mind of physicians, pharmaceutical industry, regulators, and HTAs. This seems mandatory in order to optimize drug development and to facilitate the accessibility of new therapies to the growing population of patients suffering from atopic conditions on a global level. PMID- 27716947 TI - Parasites, microbiota and metabolic disease. AB - Recent years have witnessed a dramatic increase in diseases that are ascribed to alter metabolism eventually resulting in conditions including obesity, type-2 diabetes (T2D), cardiovascular disease and metabolic syndrome (MetS). Of the many factors to which this rise has been attributed, including diet, physical activity and inflammation, several studies have correlated these disease states with alterations in gut microbiota. Simultaneously, studies have demonstrated the ability of parasites to alter microbial communities within their shared niche, leading to alterations in inflammatory processes. However, very few reports have addressed how these changes to the microbiome may be a mechanism by which parasites influence not only inflammation but also metabolic states. In this review, we attempt to draw parallels between the three capacious topics and examine the interrelationship between them. PMID- 27716948 TI - Direct oral anticoagulants in patients with atrial fibrillation and renal impairment, extremes in weight, or advanced age. AB - A growing number of patients with an indication for stroke prevention in atrial fibrillation have kidney-, age-, or weight-related alterations in pharmacokinetics that affect dosing of direct oral anticoagulants. Because these patients were excluded from or comprised a small number of patients in clinical trials, there is a lack of evidence to guide clinicians. As a consequence, many patients do not receive oral anticoagulation despite a high risk for atrial fibrillation-related stroke. Here, we present a review of direct oral anticoagulant pharmacokinetics and a review of the available clinical evidence in patients with weight-, kidney-, and age-related disease. PMID- 27716949 TI - Skin Exposure to Ultraviolet B Rapidly Activates Systemic Neuroendocrine and Immunosuppressive Responses. AB - The back skin of C57BL/6 mice was exposed to a single 400 mJ cm-2 dose of ultraviolet B (UVB), and parameters of hypothalamic-pituitary-adrenal (HPA) axis in relation to immune activity were tested after 30-90 min following irradiation. Levels of brain and/or plasma corticotropin-releasing hormone (CRH), beta endorphin, ACTH and corticosterone (CORT) were enhanced by UVB. Hypophysectomy had no effect on UVB-induced increases of CORT. Mitogen-induced IFNgamma production by splenocytes from UVB-treated mice was inhibited at 30, 90 min and after 24 h. UVB also led to inhibition of IL-10 production indicating an immunosuppressive effect on both Th1 and Th2 cytokines. Conditioned media from splenocytes isolated from UVB-treated animals had no effect on IFNgamma production in cultured normal splenocytes; however, IFNgamma increased with conditioned media from sham-irradiated animals. Sera from UVB-treated mice suppressed T-cell mitogen-induced IFNgamma production as compared to sera from sham-treated mice. IFNgamma production was inhibited in splenocytes isolated from UVB-treated animals with intact pituitary, while stimulated in splenocytes from UVB-treated hypophysectomized mice. Thus, cutaneous exposure to UVB rapidly stimulates systemic CRH, ACTH, beta-endorphin and CORT production accompanied by rapid immunosuppressive effects in splenocytes that appear to be independent of the HPA axis. PMID- 27716951 TI - Treatment of a Child With Obsessive-Compulsive Disorder With Limited Motivation: Course and Outcome of Cognitive-Behavior Therapy. AB - Motivation is a key ingredient in the successful treatment of pediatric obsessive compulsive disorder (OCD). As a first-line treatment, cognitive-behavior therapy (CBT) requires extensive client engagement, including participating in exposures and doing homework tasks. A lack of motivation to comply with these tasks may seriously affect treatment outcome. This case study identifies factors interfering with motivation and illustrates motivational strategies to enhance compliance of a child with OCD. The patient was an 11-year-old boy with severe OCD and symptoms of oppositional defiant disorder (ODD). He had extensive OCD related avoidance behavior but denied the presence of symptoms or did not acknowledge them as a problem. In this article, we discuss the different techniques used to enhance motivation, which subsequently led to a favorable outcome. PMID- 27716950 TI - Fungal diversity and seasonal succession in ash leaves infected by the invasive ascomycete Hymenoscyphus fraxineus. AB - High biodiversity is regarded as a barrier against biological invasions. We hypothesized that the invasion success of the pathogenic ascomycete Hymenoscyphus fraxineus threatening common ash in Europe relates to differences in dispersal and colonization success between the invader and the diverse native competitors. Ash leaf mycobiome was monitored by high-throughput sequencing of the fungal internal transcribed spacer region (ITS) and quantitative PCR profiling of H. fraxineus DNA. Initiation of ascospore production by H. fraxineus after overwintering was followed by pathogen accumulation in asymptomatic leaves. The induction of necrotic leaf lesions coincided with escalation of H. fraxineus DNA levels and changes in proportion of biotrophs, followed by an increase of ubiquitous endophytes with pathogenic potential. H. fraxineus uses high propagule pressure to establish in leaves as quiescent thalli that switch to pathogenic mode once these thalli reach a certain threshold - the massive feedback from the saprophytic phase enables this fungus to challenge host defenses and the resident competitors in mid-season when their density in host tissues is still low. Despite the general correspondence between the ITS-1 and ITS-2 datasets, marker biases were observed, which suggests that multiple barcodes provide better overall representation of mycobiomes. PMID- 27716952 TI - New Oral Anticoagulants in Nonvalvular Atrial Fibrillation. AB - The choice of an oral anticoagulant (OAC) for patients with nonvalvular atrial fibrillation (NVAF) is a major and complex clinical decision taking into account the individual risk-benefit ratio and bearing in mind the chronicity of therapy. This review focuses on the safety and efficacy of new oral anticoagulants (NOACs) compared with conventional vitamin K antagonists (VKA) in patients with NVAF. Current data suggest that NOACs are at least as effective and safe as VKAs for most NVAF subjects. The NOACs do not mandate dietary restrictions and regular pharmacodynamic monitoring, and they seem to have lesser incidence of intracranial or fatal bleeding when compared with VKAs. However, both dabigatran 150 twice daily and rivaroxaban have a slightly higher incidence of gastrointestinal bleeding when compared with VKAs. The article will delineate the current knowledge as well as scientific gaps related to the choice and dosage of anticoagulation regimens for various NVAF subsets and will address certain common clinical scenarios requiring special considerations. The article also addresses the shortcomings of NOACs: lack of therapeutic pharmacokinetic and pharmacodynamic targets, absence of tools to assess compliance and efficacy, rigid and limited dosage options, and absence of effective and inexpensive reversal agents. PMID- 27716953 TI - Validation of a serum neutralization test for detection of antibodies specific to cyprinid herpesvirus 3 in infected common and koi carp (Cyprinus carpio). AB - Cyprinid herpesvirus 3 (CyHV-3) is the aetiological agent of a serious infective, notifiable disease affecting common carp and varieties. In survivors, infection is generally characterized by a subclinical latency phase with restricted viral replication. The CyHV-3 genome is difficult to detect in such carrier fish that represent a potential source of dissemination if viral reactivation occurs. In this study, the analytical and diagnostic performance of an alternative serum neutralization (SN) method based on the detection of CyHV-3-specific antibodies was assessed using 151 serum or plasma samples from healthy and naturally or experimentally CyHV-3-infected carp. French CyHV-3 isolate 07/108b was neutralized efficiently by sera from carp infected with European, American and Taiwanese CyHV-3 isolates, but no neutralization was observed using sera specific to other aquatic herpesviruses. Diagnostic sensitivity, diagnostic specificity and repeatability of 95.9%, 99.0% and 99.3%, respectively, were obtained, as well as a compliance rate of 89.9% in reproducibility testing. Neutralizing antibodies were steadily detected in infected carp subjected to restrictive or permissive temperature variations over more than 25 months post-infection. The results suggest that this non-lethal diagnostic test could be used in the future to improve the epidemiological surveillance and control of CyHV-3 disease.

PMID- 27716955 TI - Computation of Femoral Canine Morphometric Parameters in Three-Dimensional Geometrical Models. AB - OBJECTIVE: To define and validate a method for the measurement of 3-dimensional (3D) morphometric parameters in polygonal mesh models of canine femora. STUDY DESIGN: Ex vivo/computerized model. SAMPLE POPULATION: Sixteen femora from 8 medium to large-breed canine cadavers (mean body weight 28.3 kg, mean age 5.3 years). METHODS: Femora were measured with a 3D scanner, obtaining 3D meshes. A computer-aided design-based (CAD) software tool was purposely developed, which allowed automatic calculation of morphometric parameters on a mesh model. Anatomic and mechanical lateral proximal femoral angles (aLPFA and mLPFA), anatomic and mechanical lateral distal femoral angles (aLDFA and mLDFA), femoral neck angle (FNA), femoral torsion angle (FTA), and femoral varus angle (FVA) were measured in 3D space. Angles were also measured onto projected planes and radiographic images. RESULTS: Mean (SD) femoral angles (degrees) measured in 3D space were: aLPFA 115.2 (3.9), mLPFA 105.5 (4.2), aLDFA 88.6 (4.5), mLDFA 93.4 (3.9), FNA 129.6 (4.3), FTA 45 (4.5), and FVA -1.4 (4.5). Onto projection planes, aLPFA was 103.7 (5.9), mLPFA 98.4 (5.3), aLDFA 88.3 (5.5), mLDFA 93.6 (4.2), FNA 132.1 (3.5), FTA 19.1 (5.7), and FVA -1.7 (5.5). With radiographic imaging, aLPFA was 109.6 (5.9), mLPFA 105.3 (5.2), aLDFA 92.6 (3.8), mLDFA 96.9 (2.9), FNA 120.2 (8.0), FTA 30.2 (5.7), and FVA 2.6 (3.8). CONCLUSION: The proposed method gives reliable and consistent information about 3D bone conformation. Results are obtained automatically and depend only on femur morphology, avoiding any operator related bias. Angles in 3D space are different from those measured with standard radiographic methods, mainly due to the different definition of femoral axes. PMID- 27716956 TI - FAAH Gene Variation Moderates Stress Response and Symptom Severity in Patients with Posttraumatic Stress Disorder and Comorbid Alcohol Dependence. AB - BACKGROUND: A common single nucleotide polymorphism (C385A) in the human fatty acid amide hydrolase (FAAH) gene has been associated with decreased distress responses in healthy volunteers, but its role in psychiatric disorders remains unknown. Here, we obtained genotypes and carried out a secondary analysis of subjects from a trial of comorbid posttraumatic stress disorder (PTSD) and alcohol dependence (AD). We evaluated the effects of C385A variation on behavioral and biochemical biomarkers of distress responses. METHODS: Forty-nine patients with PTSD and AD were admitted for 4 weeks to an experimental medicine unit at the National Institutes of Health Clinical Center. Following detoxification, stress reactivity and peripheral endocannabinoid (eCB) levels were assessed in response to a challenge session using personalized auditory guided imagery. Over the course of the study, subjects were also evaluated for changes in PTSD symptom severity. RESULTS: FAAH C385A allele carriers showed a marked increase in serum anandamide levels at baseline and throughout the stress challenge procedure compared with C allele homozygotes, while levels of eCBs primarily metabolized through other enzymatic activity, such as 2 arachidonoylglycerol, did not differ between genotype groups. FAAH C385A carriers also had decreased subjective anxiety responses to the stress challenge. Similar effects of FAAH C385A genotype were found at the level of clinical PTSD symptom severity, in particular in the arousal domain. CONCLUSIONS: This is to our knowledge the first study showing that FAAH C385A variation modulates stress responses in subjects with disorders characterized by increased stress reactivity. These findings point to the eCB pathway as a promising target for future antistress therapeutics. PMID- 27716958 TI - Reproducibility of Experiments with Laboratory Animals: What Should We Do Now? PMID- 27716957 TI - Alcohol Withdrawal Increases Protein Kinase A Activity in the Rat Inferior Colliculus. AB - BACKGROUND: Cyclic AMP-dependent protein kinase A (PKA) signaling is a key target for the action of alcohol and may therefore play a role in the pathophysiology of alcohol withdrawal seizures (AWSs). Here, we investigated the role of PKA activity with respect to increased seizure susceptibility in rats that were subjected to alcohol withdrawal. METHODS: Adult male Sprague Dawley rats received 3 daily doses of ethanol (EtOH) (or vehicle) for 4 consecutive days. Rats were then tested for susceptibility to acoustically evoked AWSs 3, 24, and 48 hours after the last alcohol dose. In separate experiments, the inferior colliculus (IC) was collected at these same time points from rats subjected to alcohol withdrawal and control rats following alcohol withdrawal. PKA activity, catalytic Calpha (PKACalpha ) protein, regulatory RIIalpha (PKARIIalpha ) protein, and RIIbeta (PKARIIbeta ) protein were measured in the IC. Lastly, in situ pharmacological studies were performed to evaluate whether inhibiting PKA activity in the IC suppressed AWSs. RESULTS: In the EtOH-treated group, AWSs were observed at the 24-hour time point, but not at the 3-hour or 48-hour time points. In the IC, PKA activity was significantly higher both 3 hours (i.e., before AWS susceptibility) and 24 hours after the last alcohol dose (when AWS susceptibility peaked) than in control rats. Consistent with these findings, protein levels of the PKACalpha subunit were significantly increased in the IC both 3 and 24 hours after the last alcohol dose. Lastly, in situ inhibition of PKA activity within the IC suppressed AWSs. CONCLUSIONS: The increase in PKA activity and PKACalpha protein expression in the IC preceded the occurrence of AWSs, and inhibiting PKA activity within the IC suppressed acoustically evoked AWSs. Together, these findings suggest that altered PKA activity plays a key role in the pathogenesis of AWSs. PMID- 27716959 TI - First record of Tetramicra brevifilum in lumpfish (Cyclopterus lumpus, L.). AB - A microsporidian species with 98.3-98.4% nucleotide identity to Tetramicra brevifilum (Journal of Fish Diseases, 3, 1980, 495) was diagnosed in lumpfish (Cyclopterus lumpus, L.) broodstock held at a breeding and rearing facility in western Ireland. The fish were wild-caught from the west coast of Ireland, and the first case was diagnosed one year after capture. Clinical signs included severe bloating, lethargy, exophthalmos, anorexia, white patches on the cornea and externally visible parasitic cysts on skin and fins. Necropsy revealed severe ascites, white nodules and vacuoles in all the internal organs and partial liquefaction of the skeletal muscle. On histological examination, microsporidian xenomas were observed in all internal organs, the skin, skeletal muscle, gills and the eyes. The microsporidian species was identified by molecular analysis and transmission electron microscopy. This is the first record of T. brevifilum infecting lumpfish, and the disease is considered to be of potential significance to the rising aquaculture industry of this species.

PMID- 27716961 TI - Left ventricular stiffness estimated by diastolic wall strain is associated with paroxysmal atrial fibrillation in structurally normal hearts. AB - BACKGROUND: Left ventricular (LV) diastolic dysfunction depends on an impaired relaxation and stiffness. Abnormal LV relaxation contributes to the development of atrial fibrillation (AF), but the role of LV stiffness in AF remains unclear. HYPOTHESIS: Diastolic wall strain (DWS), a load-independent, noninvasive direct measure of LV stiffness, correlates with prevalent AF. METHODS: This study included 328 consecutive subjects with structurally normal hearts: 164 paroxysmal AF patients and 164 age- and sex-matched (1:1) controls. We calculated the DWS from the M-mode echocardiographic measurements of the LV posterior wall thickness at end-systole and end-diastole during sinus rhythm. RESULTS: The DWS was lower in the AF patients (0.35 +/- 0.07) than in the controls (0.41 +/- 0.06; P < 0.001). After adjusting for the risk factors of AF using a conditional logistic regression analysis, a history of hypertension, plasma brain-type natriuretic peptide level, and DWS were independently associated with AF prevalence, whereas body mass index, LV mass index, left atrial volume, and any conventional indices of the diastolic function were not. A low DWS (<0.380) was the strongest indicator of AF (odds ratio: 6.22, 95% confidence interval: 3.08-14.2, P < 0.001). CONCLUSIONS: Increased LV stiffness estimated by DWS was a strong determinant of the prevalence of AF. LV stiffness may play a role in the pathogenesis of paroxysmal AF in structurally normal hearts. PMID- 27716962 TI - Acetaldehyde Disrupts Interferon Alpha Signaling in Hepatitis C Virus-Infected Liver Cells by Up-Regulating USP18. AB - BACKGROUND: Alcohol consumption exacerbates the pathogenesis of hepatitis C virus (HCV) infection and worsens disease outcomes. The exact reasons are not clear yet, but they might be partially attributed to the ability of alcohol to further suppress the innate immunity. Innate immunity is known to be already decreased by HCV in liver cells. METHODS: In this study, we aimed to explore the mechanisms of how alcohol metabolism dysregulates IFNalpha signaling (STAT1 phosphorylation) in HCV+ hepatoma cells. To this end, CYP2E1+ Huh7.5 cells were infected with HCV and exposed to the acetaldehyde (Ach) generating system (AGS). RESULTS: Continuously produced Ach suppressed IFNalpha-induced STAT1 phosphorylation, but increased the level of a protease, USP18 (both measured by Western blot), which interferes with IFNalpha signaling. Induction of USP18 by Ach was confirmed in primary human hepatocyte cultures and in livers of ethanol-fed HCV transgenic mice. Silencing of USP18 by specific siRNA attenuated the pSTAT1 suppression by Ach. The mechanism by which Ach down-regulates pSTAT1 is related to an enhanced interaction between IFNalphaR2 and USP18 that finally dysregulates the cross talk between the IFN receptor on the cell surface and STAT1. Furthermore, Ach decreases ISGylation of STAT1 (protein conjugation of a small ubiquitin-like modifier, ISG15, Western blot), which preserves STAT1 activation. Suppressed ISGylation leads to an increase in STAT1 K48 polyubiquitination which allows pSTAT1 degrading by proteasome. CONCLUSIONS: We conclude that Ach disrupts IFNalpha-induced STAT1 phosphorylation by the up-regulation of USP18 to block the innate immunity protection in HCV-infected liver cells, thereby contributing to HCV-alcohol pathogenesis. This, in part, may explain the mechanism of HCV infection exacerbation/progression in alcohol-abusing patients.

PMID- 27716964 TI - Immediate Neural Plasticity Involving Reaction Time in a Saccadic Eye Movement Task is Intact in Children With Fetal Alcohol Spectrum Disorder. AB - BACKGROUND: Saccades are rapid eye movements that bring an image of interest onto the retina. Previous research has found that in healthy individuals performing eye movement tasks, the location of a previous visual target can influence performance of the saccade on the next trial. This rapid behavioral adaptation represents a form of immediate neural plasticity within the saccadic circuitry. Our studies have shown that children with fetal alcohol spectrum disorder (FASD) are impaired on multiple saccade measures. We therefore investigated these previous trial effects in typically developing children and children with FASD to measure sensory neural plasticity and how these effects vary with age and pathology. METHODS: Both typically developing control children (n = 102; mean age = 10.54 +/- 3.25; 48 males) and children with FASD (n = 66; mean age = 11.85 +/- 3.42; 35 males) were recruited from 5 sites across Canada. Each child performed a visually guided saccade task. Reaction time and saccade amplitude were analyzed and then assessed based on the previous trial. RESULTS: There was a robust previous trial effect for both reaction time and amplitude, with both the control and FASD groups displaying faster reaction times and smaller saccades during alternation trials (visual target presented on the opposite side to the previous trial). Children with FASD exhibited smaller overall mean amplitude and smaller amplitude selectively on alternation trials compared with controls. The effect of the previous trial on reaction time and amplitude did not differ across childhood and adolescent development. CONCLUSIONS: Children with FASD did not display any significant reaction time differences, despite exhibiting numerous deficits in motor and higher level cognitive control over saccades in other studies. These results suggest that this form of immediate neural plasticity in response to sensory information before saccade initiation remains intact in children with FASD. In contrast, the previous trial effect on amplitude suggests that the motor component of saccades may be affected, signifying differential vulnerability to prenatal alcohol exposure. PMID- 27716965 TI - Normalizing GDNF expression in the spinal cord alleviates cutaneous hyperalgesia but not ongoing pain in a rat model of bone cancer pain. AB - Bone cancer pain (BCP) is the most common complication in patients with bone cancer. Glial cell line-derived neurotrophic factor (GDNF) is believed to be involved in chronic pain conditions. In this article, the expression and roles of GDNF were studied in a rat model of BCP induced by tibia injection of Walker 256 rat mammary gland carcinoma cells. Significant mechanical and thermal hyperalgesia and ongoing pain were observed beginning as early as day 5 post injection. The expression level of GDNF protein examined on day 16 after tibia injection was decreased in the L3 dorsal root ganglion (DRG) and lumbar spinal cord, but not in other spinal levels or the anterior cingulate cortex. Phosphorylation of Ret, the receptor for GDNF family ligands, was also decreased. Furthermore, normalizing GDNF expression with lentiviral vector constructs in the spinal cord significantly reduced mechanical and thermal hyperalgesia, spinal glial activation, and pERK induction induced by tibia injection, but did not affect ongoing pain. Together these findings provide new evidence for the use of GDNF as a therapeutic treatment for bone cancer pain states. PMID- 27716966 TI - The electrophysiological signature of deliberate rule violations. AB - Humans follow rules by default, and violating even simple rules induces cognitive conflict for the rule breaker. Previous studies revealed this conflict in various behavioral measures, including response times and movement trajectories. Based on these experiments, we investigated the electrophysiological signature of deliberately violating a simple stimulus-response mapping rule. Such rule violations were characterized by a delayed and attenuated P300 component when evaluating a rule-relevant stimulus, most likely reflecting increased response complexity. This parietal attenuation was followed by a frontal positivity for rule violations relative to correct response trials. Together, these results reinforce previous findings on the need to inhibit automatic S-R translation when committing a rule violation, and they point toward additional factors involved in rule violation. Candidate processes such as negative emotional responses and increased monitoring should be targeted by future investigations. PMID- 27716967 TI - Estimation of dielectric values for tissue water in the Terahertz range. AB - As the availability of Terahertz (THz) sources and their application expands, interaction with biological material needs to be well-understood. In order to accurately estimate the energy absorption pattern in skin and other tissues in the THz and far Infrared regions, values of dielectric parameters epsilon and sigma are required. We present an approach for tissue water, which uses literature values of complex refractive index for pure water together with some considerations regarding the effects of dissolved salts. The approach also involves modeling of Debye and Lorentz absorption parameters, which provides a method for the estimation of epsilon and sigma in other tissues.

PMID- 27716968 TI - Special considerations for therapeutic choice of non-vitamin K antagonist oral anticoagulants for Japanese patients with nonvalvular atrial fibrillation. AB - Nonvalvular atrial fibrillation (AF) is a risk factor for stroke in elderly patients. Although warfarin has been used to prevent AF-associated stroke for more than 50 years, non-vitamin K antagonist oral anticoagulants (NOACs) including dabigatran, rivaroxaban, apixaban, and edoxaban recently have been developed to overcome the disadvantages of warfarin. Based on the results of NOAC clinical trials, Savelieva and Camm made recommendations regarding selection of NOACs in patients with nonvalvular AF. Recent accumulating evidence indicates that NOACs work differently in Asian and non-Asian individuals. In this review, we discuss the results of the large, randomized, phase 3 international clinical trials on NOACs, the subanalyses of Asians, and a Japanese phase 3 clinical trial of rivaroxaban to discriminate Japanese patient-specific characteristics with regard to their responses to NOACs and make recommendations. Our analysis revealed that rivaroxaban decreased the incidence of gastrointestinal (GI) bleeding compared with warfarin in Japanese patients. The efficacy results showed that rivaroxaban significantly decreased the incidence of ischemic stroke (hazard ratio: 0.40, 95% confidence interval: 0.17-0.96) compared with warfarin. The lower incidence of GI bleeding and ischemic stroke may be specific to Japanese patients. Based on the present and previous results, the following recommendations regarding the selection of NOACs are added in the Camm chart for Japanese patients: edoxaban for patients with a high risk of bleeding and those with a previous stroke; and rivaroxaban for patients with a high risk of ischemic stroke and a low bleeding risk, and those with previous GI bleeding. PMID- 27716969 TI - Contribution of biomechanical forces to inflammation-induced bone resorption. AB - AIM: This study aimed to evaluate the contribution of biomechanical loading to inflammation-induced tissue destruction. MATERIALS AND METHODS: A total of 144 adult Holtzman rats were randomly assigned into four experimental groups: control (C), ligature-induced periodontal disease (P), orthodontic movement (OM), and combination group (OMP). On days 1, 3, 7, and 15, following baseline, nine animals from each experimental group were killed. Bone volume fraction (BVF) and bone mineral density (BMD) were measured using micro-computed tomography. Expression and synthesis profile of cytokines and receptors of inflammation in gingival tissues were evaluated by PCR array assay and multiplex immunoassay. RESULTS: At 15 days, the OMP group presented a significantly (p < 0.05) lower BVF and BMD levels when compared to all the other groups. The OMP group presented the highest number of upregulated protein targets in comparison to the other groups. Furthermore, the gene expression and protein levels of CCL2, CCL3, IL-1beta, IL1 alpha, IL-18, TNF-alpha, and VEGF were significantly (p < 0.05) higher in the OMP group when compared to the P group. CONCLUSIONS: In summary, mechanical loading modulates the inflammatory response of periodontal tissues to periodontal disease by increasing the expression of several pro-inflammatory mediators and receptors, which leads to increased bone resorption.

PMID- 27716970 TI - Soft tissue volume augmentation at dental implant sites using a volume stable three-dimensional collagen matrix - histological outcomes of a preclinical study. AB - AIM: The aim of this study was to test whether or not soft tissue augmentation with a collagen matrix (VCMX) leads to a similar increase in ridge width around dental implants compared to the use of an autogenous subepithelial connective tissue graft (SCTG). MATERIALS AND METHODS: In 12 dogs, immediate dental implants were placed with simultaneous guided bone regeneration. Three months later, soft tissue volume augmentation was performed by randomly allocating three treatment modalities to these sites [VCMX, SCTG, sham-operated group (control)]. Dogs were sacrificed at 1 (n = 4), 2 (n = 4) or 6 months (n = 4). Descriptive histology and histomorphometric measurements for soft tissue thickness were performed on non decalcified sections. RESULTS: The horizontal soft tissue thickness was maximal at the most coronal level (alveolar crest) at 1 month (VCMX: 2.1 +/- 1.6 mm; SCTG: 2.5 +/- 1.7 mm; p = 0.877) and decreased until 6 months. At 6 months, the greatest mucosal thickness was at a level 3.5 mm below the crest (VCMX: 0.8 +/- 0.3 mm; SCTG: 0.7 +/- 0.2 mm) (p = 0.754). Control sites revealed no relevant soft tissue augmentation at any level and any time-point. Tissue integration for VCMX and SCTG were favourable with minimal inflammatory reactions. CONCLUSIONS: Soft tissue volume augmentation at implant sites was obtained to a similar extent using VCMX and SCTG up to 2 months. Thereafter, degradation and remodelling processes were enhanced leading to a minimal increase in soft tissue thickness at 6 months for VCMX and SCTG.

PMID- 27716975 TI - When more is better: how data sharing would accelerate genomic selection of crop plants. AB - Genomic selection is proving an effective new strategy for increasing breeding efficiency in a wide variety of cereal species - the staple crops that feed the world. A preponderance of studies, reviewed here, has confirmed that the more correlated phenotypic and environmental data that are used to feed genomics assisted breeding models, the better the prediction accuracies of the models and the more useful the breeding outcomes. We argue that based on these empirical results, new alliances to share data across genomic selection breeding programs are critical to the rapid development and deployment of new crop varieties. PMID- 27716976 TI - Exploration of Core Symptoms for the Diagnosis of Alcohol Dependence in the ICD 10. AB - BACKGROUND: The classification of alcohol use disorder has changed over the past century. Now, the conceptualization of alcohol dependence is still controversial. Accumulating evidence has shown the reliability and validity for the diagnosis of alcohol dependence in the ICD-10 and DSM-IV. However, the meaning and association of the respective diagnostic items, which are descriptive of representative symptoms, have hardly been examined. The core symptom of substance use disorder has been debated in various situations, but has never been elucidated logically. METHODS: We consecutively registered 192 patients with alcohol-related problems who visited our hospital for the first time during a certain period. The relations and principal components among the checked items of the ICD-10 diagnostic criteria were examined statistically. RESULTS: Three diagnostic items in the ICD-10 were strongly correlated with each other and were thought to form the core symptoms of alcohol dependence: "strong desire," "difficulties in controlling," and "neglect of pleasures." One major physical phenomenon, "withdrawal," seemed to complement the core symptoms in the diagnosis of alcohol dependence. Another physical phenomenon, "tolerance," was demonstrated to be a relatively independent item. The principal component analysis also demonstrated that the diagnostic item "difficulties in controlling" had the maximum component loading value, followed by 2 items, "neglect of pleasures" and "strong desire." CONCLUSIONS: The core symptomatic elements in the diagnosis of alcohol dependence were statistically suggested in this study. Knowledge of the relations and components among the diagnostic items of alcohol dependence might also be applicable to other forms of substance use dependence and behavioral addiction. PMID- 27716977 TI - The Need for a Lengthier Cryolesion Can Predict a Worse Outcome in 3D Cryoablation of AV Nodal Slow Pathway in Children. AB - BACKGROUND: Transcatheter cryoablation is a well-established technique for the treatment of atrioventricular nodal reentry tachycardia (AVNRT) in children. Nevertheless, atrioventricular nodal slow-pathway conduction may recur after an acutely successful procedure. The aim of this study was to evaluate the long-term outcome of acutely successful AVNRT cryoablations in pediatric patients in case of focal cryolesion and in case of need for High-Density Linear Lesion (HDLL) cryoablation due to focal failure. METHODS: Sixty-nine consecutive pediatric patients (30 males, mean age 12.4 +/- 3.2 years; range: 5.4-18.0 years) underwent 3D-guided cryoablation for AVNRT at our institution from July 2013 to November 2014. When a focal cryoablation was acutely unsuccessful, a 3D-guided HDLL was created delivering multiple overlapping cryolesions/cryoenergy applications from the ventricular side of the tricuspid annulus to the atrial side, including the site of focal cryoablation if transiently successful. RESULTS: No permanent cryoablation-related complications occurred. Acute success rate was 98.5% (68 out of 69): in 55.9% (38 out of 68) with focal-lesion and in 44.1% (30 out of 68) with HDLL. Mean follow-up was 25.3 months and AVNRT recurrence rate was 13.2% (nine out of 68): 5.2% (two out of 38) with focal lesion and 23.3% (seven out of 30) with HDLL (P = 0.036). CONCLUSIONS: In cryoablation of AVNRT in children, the need for a more aggressive protocol (HDLL), due to the failure of focal ablation, is strictly related to higher recurrence rates. Indeed, AVNRT recurrences after cryoablation in children seem to be due to a larger and deeper substrate rather than due to the type of energy used. PMID- 27716978 TI - Influence of Successful Chronic Hepatitis C Virus Treatment with Ledipasvir/Sofosbuvir on Warfarin Dosing Requirements in Four Veterans. AB - STUDY OBJECTIVE: To describe international normalized ratio (INR) trends and warfarin dosage adjustments required for four veterans who were receiving warfarin therapy and started treatment for hepatitis C virus (HCV) with ledipasvir/sofosbuvir with or without ribavirin. DESIGN: Case series. SETTING: Pharmacist-led anticoagulation clinic in a Veterans Affairs Health Care System. PATIENTS: Four patients aged 59-66 years who were receiving warfarin and had stable, therapeutic INRs and started ledipasvir/sofosbuvir therapy with or without ribavirin for HCV infection. MEASUREMENTS AND MAIN RESULTS: All four patients developed subtherapeutic INRs after the addition of ledipasvir/sofosbuvir with or without ribavirin. An increase in weekly warfarin dose ranging from 14-67% was required, with changes in warfarin doses starting 2 3 weeks after ledipasvir/sofosbuvir initiation. Two patients required dose reductions after HCV treatment completion, whereas the other two did not. Use of the Drug Interaction Probability Scale indicated that the interaction between warfarin and ledipasvir/sofosbuvir was doubtful (score of 1 [two patients]) or possible (score of 4 [two patients]). The mechanism of this interaction is unknown but may be related to improvements in hepatic function during HCV treatment. CONCLUSION: To our knowledge, this is the first case series describing a possible drug interaction between warfarin and ledipasvir/sofosbuvir (with or without ribavirin). Close monitoring is warranted when ledipasvir/sofosbuvir is initiated in patients receiving anticoagulation therapy with warfarin, especially those with evidence of cirrhosis prior to treatment. This is particularly important in the first month after starting treatment and the first month after completion. Failure to monitor and achieve therapeutic INR after HCV therapy completion may have the potential to result in adverse outcomes. PMID- 27716979 TI - Root coverage with connective tissue graft associated with coronally advanced flap or tunnel technique: a randomized, double-blind, mono-centre clinical trial. AB - AIM: The aim of this randomized clinical trial was to compare the coronally advanced flap (CAF) with the modified microsurgical tunnel technique (MMTT) for treatment of Miller class I and II recessions. MATERIAL AND METHODS: Forty patients with 71 gingival recessions were recruited and randomly assigned to either CAF or to MMTT. In both groups, a connective tissue graft was applied. Clinical evaluations were performed after 3, 6, and 12 months. Impressions were taken and digitally scanned three-dimensionally to evaluate the quantitative soft tissue changes in the operative region. Patient satisfaction was measured with the root coverage aesthetic score (RES). RESULTS: After a period of 12 months, significant differences were not found between the two groups. Root coverage was 98.3% for CAF and 97.2% for MMTT. The evaluation of the aesthetic outcome using RES showed good results in both groups. The RES score was in accordance with subjective patient satisfaction. There was no significant difference in the amount of volumetric changes. CONCLUSIONS: CAF and MMTT with the additional use of a graft are equally successful in covering gingival recessions of Miller class I and II, with high aesthetic results. All patients indicated their willingness for further periodontal surgery. PMID- 27716980 TI - Generating human serotonergic neurons in vitro: Methodological advances. AB - Technologies for deriving human neurons in vitro have transformed our ability to study cellular and molecular components of human neurotransmission. Three groups, including our own, have recently published methods for efficiently generating human serotonergic neurons in vitro. Remarkably, serotonergic neurons derived from each method robustly produce serotonin, express raphe genes, are electrically active, and respond to selective serotonin reuptake inhibitors in vitro. Two of the methods utilize transdifferentiation technology by overexpressing key serotonergic transcription factors. The third and most recent method involves differentiating induced pluripotent stem cells (iPSCs) to serotonergic neurons using developmental patterning cues. In this mini-review, we briefly describe the developmental programs governing serotonergic specification in vivo and how they have been harnessed to achieve serotonergic differentiation in vitro. We discuss the distinct and overlapping features of the recently published methodologies and their value in the context of in vitro disease modeling. Also see the video abstract here. PMID- 27716981 TI - Carnosic acid as a component of rosemary extract stimulates skeletal muscle cell glucose uptake via AMPK activation. AB - Compounds that increase the activity of the energy sensor AMP-activated kinase (AMPK) have the potential to regulate blood glucose levels. Although rosemary extract (RE) has been reported to activate AMPK and reduce blood glucose levels in vivo, the chemical components responsible for these effects are not known. In the present study, we measured the levels of the polyphenol carnosic acid (CA) in RE and examined the effects and the mechanism of action of CA on glucose transport system in muscle cells. High performance liquid chromatography (HPLC) was used to measure the levels of CA in RE. Parental and GLUT4myc or GLUT1myc overexpressing L6 rat myotubes were used. Glucose uptake was assessed using [3 H] 2-deoxy-d-glucose. Total and phosphorylated levels of Akt and AMPK were measured by immunoblotting. Plasma membrane GLUT4myc and GLUT1myc levels were examined using a GLUT translocation assay. Statistics included analysis of variance (ANOVA) followed by Tukey's post-hoc test. At concentrations found in rosemary extract, CA stimulated glucose uptake in L6 myotubes. At 2.0 MUmol/L CA a response (226 +/- 9.62% of control, P=.001), similar to maximum insulin (201 +/- 7.86% of control, P=.001) and metformin (213 +/- 10.74% of control, P=.001) was seen. Akt phosphorylation was not affected by CA while AMPK and ACC phosphorylation was increased and the CA-stimulated glucose uptake was significantly reduced by the AMPK inhibitor compound C. Plasma membrane GLUT4 or GLUT1 glucose transporter levels were not affected by CA. Our study shows increased muscle cell glucose uptake and AMPK activation by low CA concentrations, found in rosemary extract, indicating that CA may be responsible for the antihyperglycemic properties of rosemary extract seen in vivo. PMID- 27716982 TI - Simultaneous analysis of 35 specific antihypertensive adulterants in dietary supplements using LC/MS/MS. AB - A sensitive and specific LC/MS/MS method was developed for the simultaneous analysis of 35 compounds used for treating hypertension as adulterants in dietary supplements. The method was validated for specificity, linearity, accuracy, precision, limit of detection, limit of quantitation, stability and recovery. The limit of detection and limit of quantitation ranged from 0.20 to 20.0 and 0.50 to 60.0 ng/g, respectively. The linearity was good (r2 > 0.999), with intra- and interday precision levels of 0.43-7.87% and 0.65-9.95% and the intra- and interday accuracies of 84.36-115.82% and 83.78-118.69%, respectively. The stability (relative standard deviation) was <14.75%. The mean recovery was 80.81 117.86% (relative standard deviation <10.00%). Ninety-seven commercial dietary supplements available in South Korea were analyzed. While none contained detectable amounts of the 35 antihypertensive compounds, the developed LC/MS/MS procedure can be used for routine analysis to monitor illegal adulteration in various forms of dietary supplements. PMID- 27716983 TI - Pharmacokinetics of Ceftazidime-Avibactam in Two Patients With KPC-Producing Klebsiella pneumoniae Bacteremia and Renal Impairment. AB - Limited data exist regarding optimal dosing of ceftazidime/avibactam (C/A) in patients with unique physiology, who were excluded from published clinical trials. Data are also lacking regarding clinical efficacy of C/A in patients with infections due to multidrug-resistant gram-negative pathogens. To expand knowledge in these areas, we present pharmacokinetic data from two patients with Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae bloodstream infections, both of whom had renal impairment, and one of whom was morbidly obese. C/A was initiated in both patients at higher doses than those recommended in the package insert. To assess adequacy of dosing at steady state, a trough was drawn before and consecutive levels were drawn after a C/A dose such that half life and volume of distribution for ceftazidime and avibactam could be calculated using the Sawchuk-Zaske method. Both patients cleared their bloodstream infection without evidence of toxicity. Patient 1 and patient 2 had prolonged half-lives for ceftazidime (22.8 and 14.5 hours, respectively) and avibactam (19.6 and 11.3 hours, respectively). Both patients had volumes of distribution significantly larger than those listed in the package insert: ceftazidime 47.1 L and 24.7 L and avibactam 50.3 L and 38.7 L for patients 1 and 2, respectively. Considering the larger volumes of distribution and levels observed in our patients, recommended doses and intervals may not be sufficient for obese patients with renal failure, especially for those infected with KPC-producing organisms. Additional efficacy and pharmacokinetic data are still needed for this agent to define optimal dosing strategies in patients commonly encountered in clinical practice.

PMID- 27716985 TI - D-tyrosine affects aggregation behavior of Pantoea agglomerans. AB - D-amino acids have been proved to disassemble biofilms by disassociating the matrix. Pantoea agglomerans is characterized by the formation of another kind of multicellular structure called symplasmata, which also remains the ability to form biofilms. In this study, a rice diazotrophic endophyte P. agglomerans YS19 was selected as a model strain to explore the effects of D-amino acids on these two kinds of cell aggregate structures. It was discovered that D-tyrosine disassociates biofilm, yet promotes symplasmata formation. D-tyrosine showed no influence on bacterial growth yet promoted the bacterial motility and inhibited the expression of cellular MalE and OmpF proteins, which enriched our knowledge of the biological effect of D-amino acids and expanded the research ideas of symplasmata formation. PMID- 27716986 TI - Evaluation of performance of veterinary in-clinic hematology analyzers. AB - BACKGROUND: A previous study provided information regarding the quality of in clinic veterinary biochemistry testing. However, no similar studies for in-clinic veterinary hematology testing have been conducted. OBJECTIVE: The objective of this study was to assess the quality of hematology testing in veterinary in clinic laboratories using results obtained from testing 3 levels of canine EDTA blood samples. METHODS: Clinicians prepared blood samples to achieve measurand concentrations within, below, and above their RIs and evaluated the samples in triplicate using their in-clinic analyzers. Quality was assessed by comparison of calculated total error with quality requirements, determination of sigma metrics, use of a quality goal index, and agreement between in-clinic and reference laboratory instruments. Suitability for statistical quality control was determined using adaptations from the computerized program, EZRules3. RESULTS: Evaluation of 10 veterinary in-clinic hematology analyzers showed that these instruments often fail to meet quality requirements. At least 60% of analyzers reasonably determined RBC, WBC, HCT, and HGB, when assessed by most quality goal criteria; platelets were less reliably measured, with 80% deemed suitable for low platelet counts, but only 30% for high platelet counts, and automated differential leukocyte counts were generally considered unsuitable for clinical use with fewer than 40% of analyzers meeting the least stringent quality goal requirements. Fewer than 50% of analyzers were able to meet requirements for statistical quality control for any measurand. CONCLUSION: These findings reflect the current status of in-clinic hematology analyzer performance and provide a basis for future evaluations of the quality of veterinary laboratory testing. PMID- 27716987 TI - Efficacy of imidazolquinoline on treatment of condyloma acuminatum of the buccal mucosa. AB - The condylomata acuminata is a benign epithelial neoplasm induced by papillomavirus, and it is characterized by the proliferation of stratified squamous epithelial tissue that affects the anogenital and oral mucosa. It is considered to be a sexually transmitted disease and has a higher prevalence in individuals infected with human immunodeficiency virus. Various therapies have been used for the removal of lesions, such as cryotherapy, surgical laser and surgical excision, which are painful and scarring. These techniques, however, do not eliminate the virus and relapses are common shortly after treatment. The use of immunomodulators has been proposed to be an alternative treatment, as imidazolquinoline has been shown to be effective in the treatment of lesions in the anogenital region. However, its use in the oral cavity has been the subject of few reports in the literature. Thus, the objective of this study is to describe a case of warts in the labial mucosa of an HIV positive patient using imidazolquinoline 5%. PMID- 27716990 TI - Evaluation of the American college of surgeons thyroid and parathyroid ultrasound course: Results of a web-based survey. AB - OBJECTIVES/HYPOTHESIS: The American College of Surgeons Thyroid and Parathyroid Ultrasound Skills-Oriented Course (TPUSC) was designed to teach surgeons how to interpret and perform office-based head and neck ultrasound (HNUS). The objective of this study was to survey attendees of the TPUSC to evaluate the usefulness of the course, to track surgeon performed HNUS practice patterns, and to help identify potential roadblocks to incorporation of HNUS into a surgeon's practice. STUDY DESIGN: Cross-sectional survey. METHODS: A Web-based survey was sent to 952 surgeons who completed the TPUSC between 2010 and 2014. Questions included surgeon specialty, practice type, Likert scale rating of the TPUSC, competency with different HNUS procedures, and current HNUS practice patterns. RESULTS: The response rate was 24%. On a scale from 1 (not useful) to 5 (extremely valuable), the mean course usefulness rating was 4.2. Educational goals were met for 194 (92%) surgeons, and 162 (77%) surgeons reported performing HNUS in their practice. Of 48 surgeons not performing HNUS, 24 (50%) attributed insufficient time in their clinic schedule, and 21 (44%) attributed high equipment costs. CONCLUSIONS: The TPUSC is a valuable educational experience for surgeons seeking to gain proficiency in HNUS. The majority of TPUSC graduates gain competency with at least one type of HNUS procedure following the course. LEVEL OF EVIDENCE: NA Laryngoscope, 127:1950-1958, 2017. PMID- 27716989 TI - Doctors Have no Right to Refuse Medical Assistance in Dying, Abortion or Contraception. AB - In an article in this journal, Christopher Cowley argues that we have 'misunderstood the special nature of medicine, and have misunderstood the motivations of the conscientious objectors'. We have not. It is Cowley who has misunderstood the role of personal values in the profession of medicine. We argue that there should be better protections for patients from doctors' personal values and there should be more severe restrictions on the right to conscientious objection, particularly in relation to assisted dying. We argue that eligible patients could be guaranteed access to medical services that are subject to conscientious objections by: (1) removing a right to conscientious objection; (2) selecting candidates into relevant medical specialities or general practice who do not have objections; (3) demonopolizing the provision of these services away from the medical profession. PMID- 27716991 TI - Early-Onset 5-Fluorouracil Toxicity in a Patient Negative for Dihydropyrimidine Dehydrogenase Mutations: The Clinical Course of Reversal with Uridine Triacetate. AB - An antimetabolite pyridine analog, 5-fluorouracil (5-FU), is used to treat solid tumors. Early toxicities may occur at standard doses of 5-FU due to dihydropyrimidine dehydrogenase (DPD) deficiency. Uridine triacetate, approved by the Food and Drug Administration in 2015, is an oral prodrug of uridine, a pharmacologic antidote for 5-FU toxicity. To our knowledge, this is the first case report that documents the clinical course of a patient treated with uridine triacetate to reverse early-onset 5-FU toxicity negative for DPD mutations. We describe the case of a 73-year-old man with anal cancer treated with standard-of care chemotherapy and radiation. Two days after completion of his initial 5-FU infusion, the patient developed severe mucositis and extreme fatigue, followed by a rapid decline in his blood cell counts and fevers. The patient was initiated on uridine triacetate 86 hours after completion of his 5-FU infusion. Over a 10-day hospital length of stay, the patient's absolute neutrophil count recovered to within normal limits, and his mucositis significantly improved. At follow-up visits, the patient denied any residual symptoms of 5-FU toxicity. We describe the patient's clinical course from hospital presentation to 31 days after initiation of uridine triacetate. PMID- 27716988 TI - Progression of alpha-synuclein pathology in multiple system atrophy of the cerebellar type. AB - AIMS: The aim of this study was to identify early foci of alpha-synuclein (alpha syn pathology) accumulation, subsequent progression and neurodegeneration in multiple system atrophy of the cerebellar type (MSA-C). METHODS: We analysed 70 MUm-thick sections of 10 cases with MSA-C and 24 normal controls. RESULTS: MSA-C cases with the lowest burden of pathology showed alpha-syn glial cytoplasmic inclusions (GCIs) in the cerebellum as well as in medullary and pontine cerebellar projections. Cerebellar pathology was highly selective and severely involved subcortical white matter, whereas deep white matter and granular layer were only mildly affected and the molecular layer was spared. Loss of Purkinje cells increased with disease duration and was associated with neuronal and axonal abnormalities. Neocortex, basal ganglia and spinal cord became consecutively involved with the increasing burden of alpha-syn pathology, followed by hippocampus, amygdala, and, finally, the visual cortex. GCIs were associated with myelinated axons, and the severity of GCIs correlated with demyelination. CONCLUSIONS: Our findings indicate that cerebellar subcortical white matter and cerebellar brainstem projections are likely the earliest foci of alpha-syn pathology in MSA-C, followed by involvement of more widespread regions of the central nervous system and neurodegeneration with disease progression. PMID- 27716992 TI - Bone mineral density is associated with left ventricular diastolic function in women. AB - BACKGROUND: Low bone mineral density (BMD) and left ventricular (LV) diastolic function are associated with heart failure. However, little is known about the association between BMD and LV diastolic function. HYPOTHESIS: BMD is independently related to LV diastolic function in women. METHODS: We conducted a cross-sectional study of 432 women. Brachial-ankle pulse wave velocity (baPWV) and BMD measurements were performed. LV diastolic function and structure were assessed by echocardiographic examination. RESULTS: BaPWV and the percentage of LV diastolic dysfunction increased with progressive bone loss. Moreover, partial correlation analysis demonstrated that BMD at spine L2-4 and at femoral neck were correlated with baPWV and LV diastolic function parameters after adjusting covariates. Multivariate logistic regression analysis revealed that osteoporosis was independently associated with LV diastolic dysfunction in women. CONCLUSIONS: Osteoporosis is independently associated with LV diastolic dysfunction in women. A prospective study is needed to elucidate the effects of BMD on cardiac function in women. PMID- 27716993 TI - Bone metabolism markers: Indicators of loading dose intravenous ibandronate treatment for bone metastases from breast cancer. AB - To investigate the changes in bone metabolism markers after second-line treatment with loading dose intravenous (i.v.) ibandronate in patients with bone metastases (BM) from breast cancer, 80 patients were enrolled in this study during January 2010 to April 2014. All the patients were treated with a second-line loading dose ibandronate for advanced breast cancer with BM and moderate-to-severe bone pain. Ibandronate (6 mg) was intravenously administered on three consecutive days followed by maintenance treatment every 3-4 weeks. Clinical data, including pain score, Karnofsky performance status (KPS) score, and changes in bone metabolism markers, were analyzed. Sixty-two patients were included in the final analysis. Compared with their pre-treatment scores, patients exhibited significantly increased KPS scores (P < .01) and a reduced dose of analgesic medication (oxycodone) (P < .01) after 3 and 6 weeks' post-treatment. The levels of serum bone alkaline phosphatase (BAP), tartrate-resistant acid phosphatase (TRACP-5b), and cross-linked carboxy-terminal telopeptide of type I collagen (ICTP) were significantly reduced after 3 and 6 weeks' post-treatment (P < .001). Aside from a few adverse events, no liver or renal toxicity was observed. Bone metabolism markers decreased by varying degrees after treatment with a loading dose of ibandronate in patients with BM from breast cancer. It might be convenient using bone metabolism markers to potentially evaluate the efficacy of bisphosphonates treatment for bone metastasis. PMID- 27716994 TI - Dopamine D3 receptor knockout mice exhibit abnormal nociception in a sex different manner. AB - Pain is a complex and subjective experience. Previous studies have shown that mice lacking the dopamine D3 receptor (D3RKO) exhibit hypoalgesia, indicating a role of the D3 receptor in modulation of nociception. Given that there are sex differences in pain perception, there may be differences in responses to nociceptive stimuli between male and female D3RKO mice. In the current study, we examined the role of the D3 receptor in modulating nociception in male and female D3RKO mice. Acute thermal pain was modeled by hot-plate test. This test was performed at different temperatures including 52 degrees C, 55 degrees C, and 58 degrees C. The von Frey hair test was applied to evaluate mechanical pain. And persistent pain produced by peripheral tissue injury and inflammation was modeled by formalin test. In the hot-plate test, compared with wild-type (WT) mice, D3RKO mice generally exhibited longer latencies at each of the three temperatures. Specially, male D3RKO mice showed hypoalgesia compared with male WT mice when the temperature was 55 degrees C, while for the female mice, there was a statistical difference between genotypes when the test condition was 52 degrees C. In the von Frey hair test, both male and female D3RKO mice exhibited hypoalgesia. In the formalin test, the male D3RKO mice displayed a similar nociceptive behavior as their sex-matched WT littermates, whereas significantly depressed late-phase formalin-induced nociceptive behaviors were observed in the female mutants. These findings indicated that the D3 receptor affects nociceptive behaviors in a sex specific manner and that its absence induces more analgesic behavior in the female knockout mice.

PMID- 27716996 TI - The transcription factor cyclic adenosine 3',5'-monophosphate response element binding protein enhances the odonto/osteogenic differentiation of stem cells from the apical papilla. AB - AIM: To investigate the role of cAMP response element-binding protein (CREB) in the regulation of odonto/osteogenic differentiation of stem cells from the apical papilla (SCAPs). METHODOLOGY: Stem cells from the apical papilla were obtained from human impacted third molars (n = 15). Isolated SCAPs were transfected with CREB overexpressing/silenced lentivirus. Transfected cells were stained with alizarin red to investigate mineralized nodule formation. The expression of the mineralization-related genes, alkaline phosphatase (ALP), collagen type I (Col I), runt-related transcription factor 2 (RUNX2), osterix (OSX) and osteocalcin (OCN), was determined by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Protein expression of the odontogenic-related marker dentine sialoprotein (DSP) and the osteogenic-related marker RUNX2 was measured by Western blotting analysis. One-way analysis of variance (anova) and Student's t test were used for statistical analysis (a = 0.05). RESULTS: The overexpression of CREB enhanced mineralized nodule formation and up-regulated (P < 0.05) the mRNA levels of odonto/osteogenic-related markers, including ALP, Col I, RUNX2, OSX and OCN, and also increased (P < 0.05) the protein expression of DSP and RUNX2. In contrast, the silencing of CREB inhibited (P < 0.05) the mineralization capacity of the SCAPs and decreased (P < 0.05) the expression of odonto/osteogenic-related markers. CONCLUSION: Up-regulation of CREB expression promoted odonto/osteogenic differentiation of SCAPs and provided a potential method for the regeneration of the dentine-pulp complex. PMID- 27716997 TI - Establishment of reference intervals for serum thyroid-stimulating hormone, free and total thyroxine, and free and total triiodothyronine for the Beckman Coulter DxI-800 analyzers by indirect method using data obtained from Chinese population in Zhejiang Province, China. AB - BACKGROUND: In order to establish suitable reference intervals of thyroid stimulating hormone (TSH), free (unbound) T4 (FT4), free triiodothyronine (FT3), total thyroxine (T4), and total triiodothyronine (T3) for the patients collected in Zhejiang, China, an indirect method was developed using the data from the people presented for routine health check-up. METHODS: Fifteen thousand nine hundred and fifty-six person's results were reviewed. Box-Cox or Case Rank was used to transform the data to normal distribution. Tukey and Box-Plot methods were used to exclude the outliers. Nonparametric method was used to establish the reference intervals following the EP28-A3c guideline. Pearson correlation was used to evaluate the correlation between hormone levels and age, while Mann Whitney U test was employed for quantification of concentration differences on the people who are younger and older than 50 years old. RESULTS: Reference intervals were 0.66-4.95 mIU/L (TSH), 8.97-14.71 pmol/L (FT4), 3.75-5.81 pmol/L (FT3), 73.45-138.93 nmol/L (total T4), and 1.24-2.18 nmol/L (total T3) in male; conversely, reference intervals for female were 0.72-5.84 mIU/L (TSH), 8.62-14.35 pmol/L (FT4), 3.59-5.56 pmol/L (FT3), 73.45-138.93 nmol/L (total T4), and 1.20 2.10 nmol/L (total T3). FT4, FT3, and total T3 levels in male and FT4 level in female had an inverse correlation with age. Total T4 and TSH levels in female were directly correlated. Significant differences in these hormones were also found between younger and older than 50 years old except FT3 in female. CONCLUSIONS: Indirect method can be applied for establishment of reference intervals for TSH, FT4, FT3, total T4, and total T3. The reference intervals are narrower than those previously established. Age factor should also be considered. PMID- 27716998 TI - Viewing distance and eyestrain symptoms with prolonged viewing of smartphones. AB - BACKGROUND: This paper investigates viewing distances and eyestrain symptoms in young adults reading from a smartphone for 60 minutes. METHODS: A survey related to common asthenopic (eyestrain) symptoms was administered to subjects before and after they read an extract from a novel on a smartphone for 60 minutes. Subjects rated their symptoms on a scale from zero (not at all) to four (extremely). The viewing distance to the smartphone was measured on a photograph taken of the subject every minute. Each subject used the same smartphone and read the same text. RESULTS: Subjects were 18 young adults (mean age: 21.5 +/- 3.3 years) with self-reported good health, normal visual acuity and no accommodative or binocular vision disorders. The mean viewing distance while using a smartphone over 60 minutes was 29.2 +/- 7.3 cm. The viewing distance was significantly greater during the first, second and fifth 10-minute time periods (30.6 +/- 7.2 cm, 29.7 +/- 7.3 cm and 28.9 +/- 8.5 cm, respectively) than during the final 10-minute time period (27.8 +/- 7.7 cm) (Wilcoxon, p = 0.023, 0.02 and 0.04, respectively). The total symptom score was significantly greater post-experiment (score = 8.06) than pre-experiment (score = 3.56) (Wilcoxon, p < 0.001). Symptoms of tired eyes, uncomfortable eyes and blur increased significantly after 60 minutes of smartphone use (Wilcoxon, p < 0.05). There was a significant correlation between change in total symptom score and change in viewing distance (rho = -0.51; p = 0.03). The only single symptom that correlated with a change in viewing distance was 'uncomfortable eyes' (rho = -0.52, p = 0.03). CONCLUSION: Viewing distances are closer and eyestrain symptoms are greater after reading from a smartphone for 60 minutes. The viewing distances measured were closer than those previously reported in the literature. PMID- 27716995 TI - UV-Induced DNA Damage and Mutagenesis in Chromatin. AB - UV radiation induces photolesions that distort the DNA double helix and, if not repaired, can cause severe biological consequences, including mutagenesis or cell death. In eukaryotes, both the formation and repair of UV damage occur in the context of chromatin, in which genomic DNA is packaged with histones into nucleosomes and higher order chromatin structures. Here, we review how chromatin impacts the formation of UV photoproducts in eukaryotic cells. We describe the initial discovery that nucleosomes and other DNA binding proteins induce characteristic "photofootprints" during the formation of UV photoproducts. We also describe recent progress in genomewide methods for mapping UV damage, which echoes early biochemical studies, and highlights the role of nucleosomes and transcription factors in UV damage formation and repair at unprecedented resolution. Finally, we discuss our current understanding of how the distribution and repair of UV-induced DNA damage influence mutagenesis in human skin cancers. PMID- 27716999 TI - A Rare Case of Pembrolizumab-Induced Uveitis in a Patient with Metastatic Melanoma. AB - Pembrolizumab, a programmed cell death protein 1 (PD-1) inhibitor, is a humanized monoclonal antibody used in the treatment of metastatic or unresectable melanoma and advanced non-small cell lung cancer (NSCLC). We hereby report a case of pembrolizumab-induced uveitis to increase practitioner awareness. A 78-year-old woman presented with onset of panuveitis after initiation of pembrolizumab therapy for metastatic melanoma. The patient received three cycles of therapy every 21 days, during which her symptoms progressively worsened. She was treated with topical and systemic corticosteroids, and further pembrolizumab was discontinued despite a good response to therapy. Pembrolizumab has been associated with rapid onset of ocular inflammation and uveitis. PD-1 inhibitors mediate a T-cell response against cancer cells; however, autoimmune complications have been reported. Incidence of pembrolizumab-induced uveitis is reported to be < 1%. To date, three cases have been reported since its Food and Drug Administration approval in September 2014. Uveitis, if left untreated, may lead to permanent vision loss and ocular damage. Cases of immune-mediated uveitis have been reported with cancer immunotherapies. Oncologists and ophthalmologists should be aware of this complication. With the increasing targeted pharmaceuticals in oncology, effective management of adverse events is necessary to ensure patient safety and optimal outcomes.

PMID- 27717001 TI - High-accuracy modeling of antibody structures by a search for minimum-energy recombination of backbone fragments. AB - Current methods for antibody structure prediction rely on sequence homology to known structures. Although this strategy often yields accurate predictions, models can be stereo-chemically strained. Here, we present a fully automated algorithm, called AbPredict, that disregards sequence homology, and instead uses a Monte Carlo search for low-energy conformations built from backbone segments and rigid-body orientations that appear in antibody molecular structures. We find cases where AbPredict selects accurate loop templates with sequence identity as low as 10%, whereas the template of highest sequence identity diverges substantially from the query's conformation. Accordingly, in several cases reported in the recent Antibody Modeling Assessment benchmark, AbPredict models were more accurate than those from any participant, and the models' stereo chemical quality was consistently high. Furthermore, in two blind cases provided to us by crystallographers prior to structure determination, the method achieved <1.5 Angstrom overall backbone accuracy. Accurate modeling of unstrained antibody structures will enable design and engineering of improved binders for biomedical research directly from sequence. Proteins 2016; 85:30-38.

AB - OBJECTIVES: Optimal treatment of rectal cancer (RC) requires multidisciplinary care. We examined whether distance to treatment center or community size impacts access to multimodality care and population-based outcomes in RC. METHODS: Patients diagnosed with stage II/III RC from 1999 to 2009 and treated at 1 of 6 regional cancer centers in British Columbia were reviewed. Distance to treatment center was determined for each patient. Communities were classified as rural, small, medium, and large population centers. Logistic and Cox regression models assessed associations of distance and community size with treatment received as well as cancer-specific (CSS) and overall survival (OS). RESULTS: Of 3,158 patients, 93.6% underwent surgery, 86.3% received radiotherapy, and 51.3% were treated with adjuvant chemotherapy (AC). Median time from diagnosis to oncologic consultation was longer for those >100 km from a treatment center or residing in medium/rural communities. Logistic regression demonstrated no correlation between distance or community size and receipt of treatment modality. Univariate analysis showed similar CSS (P = .18, .88) and OS (P = .36, .47) based on community size and distance, respectively. In multivariate analysis, distance >100 km had inferior CSS (Hazard Ratio [HR] 1.39, 95% CI: 1.03-1.88; P = .031). There was no consistent trend between decreasing community size and outcomes; however, living in a small center was associated with improved OS (HR 0.58, 95% CI: 0.38-0.88; P = .011) and CSS (HR 0.42, 95% CI: 0.25-0.70; P = .001). CONCLUSIONS: In this population-based study, there were no urban-rural differences in access to multidisciplinary care, but increased distance may be associated with worse cancer-specific outcomes. PMID- 27717003 TI - A Brazilian Investigation of the 36- and 16-Item Difficulties in Emotion Regulation Scales. AB - OBJECTIVE: About 10 years ago, Gratz and Roemer (2004) introduced the Difficulties in Emotion Regulation Scale (DERS), a 36-item self-report instrument measuring 6 areas of emotion regulation problems. Recently, Bjureberg et al. (2015) have introduced a new, briefer version of the DERS comprising only 16 of the 36 items included in the original version. Because no studies have yet cross validated the recently introduced 16-item DERS and the 36-item DERS has never been tested in Brazil, we sought to inspect the psychometric properties of scores from both DERS versions with a nonclinical Brazilian sample. METHOD: Participants were 725 adult volunteers aged 18-70 years (mean = 30.54, standard deviation = 10.59), 82.3% of whom were women. All were administered the DERS along with a number of other self-report and performance-based instruments. Data analyses inspected internal consistency, factor structure, and convergent as well as divergent validity of scores from both DERS versions. RESULTS: Results show that scores from both DERS versions possess good psychometric properties. Interestingly, both versions correlated, in the expected direction, with psychopathology and showed no significant correlations with cognitive measures. Like in other studies, however, the Awareness factor of the 36-item DERS did not produce optimal validity and reliability indexes. CONCLUSION: Taken together, our findings indicate that the 16-item DERS may be preferred over the 36-item version and provide additional support to the differentiation between emotion regulation and cognitive tasks of emotional perception and abstract and verbal reasoning. PMID- 27717004 TI - Mutations in idiopathic cytopenia of undetermined significance assist diagnostics and correlate to dysplastic changes. AB - Cytopenia is common in the elderly population and etiology may be difficult to assess. Here, we investigated the occurrence of mutations in patients with idiopathic cytopenia of undetermined significance and the usefulness in improving diagnostics. We included 60 patients with persistent cytopenia > 6 months without definite diagnosis of hematological neoplasm after routine assessment. Bone marrow material underwent a blinded morphology review and DNA was sequenced with a targeted 20 gene panel representing the most commonly mutated genes in myelodysplastic syndrome. Thirty seven (62%) patients carried at least one mutation at inclusion, and of these 95% carried a mutation in TET2, ASXL1, SRSF2, or DNMT3A. The most commonly mutated gene was TET2 observed in 43% of all patients. During one to eight years follow-up seven patients progressed to a myeloid neoplasm and six of these had a detectable mutation at study entry. Median time to progression was 53 months (range 10-78), and at time of progression each patient had at least two mutations detected. Mutations in TP53 and NRAS were not present in patients at inclusion, but identified as secondary hits triggering progression. The morphology review was concordant in 68% of all cases, and 93% of the cases reclassified into the group "highly suspicious for MDS" had a mutation. All patients who had a concordant review "highly suspicious for MDS" had at least two mutations detected. Overall, we show that morphology examination is challenging in this heterogeneous group and targeted sequencing helps identify patients at risk of progression. Am. J. Hematol. 91:1234-1238, 2016.

AB - This article examines the humanized birth movement in Mexico and analyzes how the remaking of tradition-the return to traditional birthing arts (home birth, midwife-assisted birth, natural birth)-inadvertently reinscribes racial hierarchies. The great irony of the humanized birth movement lies in parents' perspective of themselves as critics of late capitalism. All the while, their very rejection of consumerism bolsters ongoing commodification of indigenous culture and collapses indigeneity, nature, and tradition onto one another. While the movement is quickly spreading across Mexico, indigenous women and their traditional midwives are largely excluded from the emerging humanized birth community. Through ethnographic examples, the article suggests that indigenous individuals are agentive actors who appropriate cards in decks stacked against them. Examples of resistance emerge within a context of power and political economy that often capitalizes on images of indigeneity while obscuring the lives, experiences, and opinions of indigenous people.

AB - The gliding aquatic bacterium Flavobacterium columnare causes columnaris disease, a common problem for wild and farmed freshwater fish worldwide. Recently, a broth microdilution method was standardized to test the susceptibility of F. columnare against antimicrobials commonly used in aquaculture. We used this new method to measure the minimal inhibitory concentrations (MICs) of ten antimicrobials against 120 F. columnare isolates. The resulting MIC frequency distributions for each antimicrobial (1 MIC/isolate) were used to estimate epidemiological cut-off values (ECVs) which separate isolates with typical wild-type (WT) susceptibility from isolates with decreased non-wild-type (NWT) susceptibility. We identified 22 NWT isolates with elevated MICs relative to the ECV that covered 99.9% of the MIC distribution against one or more of the antimicrobials: ampicillin, enrofloxacin, erythromycin, florfenicol, flumequine, oxolinic acid or oxytetracycline. Ten of the NWT isolates had decreased susceptibility to a single antimicrobial class, six isolates to two antimicrobial classes and six isolates to three or more antimicrobial classes. The MIC frequency distributions and provisional cut-off values provide data needed to set epidemiological cut-off values to monitor for the development of antimicrobial resistance among F. columnare.

AB - The stratum corneum or horny layer is the uppermost layer of the epidermis, and is mainly responsible for the skin's barrier function. In spite of its complexity at the ultrastructural and molecular level, the features accessible to visualization on conventional histology are relatively limited. Nevertheless, knowledge of subtle clues that one may observe in the stratum corneum can prove useful in a wide range of situations in dermatopathology. We herein review a selection of common and rare entities in which the horny layer may reveal significantly important hints for the diagnosis. These clues include parakeratosis and its different patterns (focal, confluent, alternating, associated with spongiosis, epidermal hyperplasia or lichenoid changes), subcorneal acantholysis, infectious organisms in the stratum corneum (including fungal, bacterial and parasitic), thickening or thinning of the stratum corneum and the presence of different kinds of pigment. Even when normal, the horny layer may prove to be useful when seen in association with severe epidermal damage, a combination of features testifying to the acute nature of the underlying pathological process. PMID- 27717005 TI - Specifically neuropathic Gaucher's mutations accelerate cognitive decline in Parkinson's. AB - OBJECTIVE: We hypothesized that specific mutations in the beta-glucocerebrosidase gene (GBA) causing neuropathic Gaucher's disease (GD) in homozygotes lead to aggressive cognitive decline in heterozygous Parkinson's disease (PD) patients, whereas non-neuropathic GD mutations confer intermediate progression rates. METHODS: A total of 2,304 patients with PD and 20,868 longitudinal visits for up to 12.8 years (median, 4.1) from seven cohorts were analyzed. Differential effects of four types of genetic variation in GBA on longitudinal cognitive decline were evaluated using mixed random and fixed effects and Cox proportional hazards models. RESULTS: Overall, 10.3% of patients with PD and GBA sequencing carried a mutation. Carriers of neuropathic GD mutations (1.4% of patients) had hazard ratios (HRs) for global cognitive impairment of 3.17 (95% confidence interval [CI], 1.60-6.25) and a hastened decline in Mini-Mental State Exam scores compared to noncarriers (p = 0.0009). Carriers of complex GBA alleles (0.7%) had an HR of 3.22 (95% CI, 1.18-8.73; p = 0.022). By contrast, the common, non neuropathic N370S mutation (1.5% of patients; HR, 1.96; 95% CI, 0.92-4.18) or nonpathogenic risk variants (6.6% of patients; HR, 1.36; 95% CI, 0.89-2.05) did not reach significance. INTERPRETATION: Mutations in the GBA gene pathogenic for neuropathic GD and complex alleles shift longitudinal cognitive decline in PD into "high gear." These findings suggest a relationship between specific types of GBA mutations and aggressive cognitive decline and have direct implications for improving the design of clinical trials.

AB - Local rural and indigenous communities have assumed increasing responsibility for conservation within and between areas buffering the impacts of agricultural or resource-extraction zones and protected areas. Empowering local communities as central partners in conservation and climate-change mitigation has allowed many people to gain access to land and citizenship rights but has provided limited improvements in access to social services and economic opportunities even as expectation about their role as environmental stewards grows. These expectations, however, are inconsistent with reality. We conducted multiple field studies in Brazil since the mid-1980s to illustrate the discrepancies between conservation programs and local conditions and expectations. We suggest that public policies and conservation programs should not delegate responsibility for managing protected areas to local and indigenous communities without considering local needs and expectations and locals' attitudes toward conservation. In other words, behavior that maintains or improves the environment should not be treated as traditional based on the expectations of outsiders. Framing local populations as traditional environmentalists creates contradictions and frustrations for local populations and for conservation professionals and policy makers.

Electrical current (11.9 MUA mg-1 ) and potential (525 mV) are reversibly produced by localized acetonitrile doping under ambient conditions.

PMID- 27717013 TI - Increased troponin I is associated with fatal outcome in acquired thrombotic thrombocytopenic purpura. AB - Thrombotic thrombocytopenic purpura (TTP) has >90% mortality without therapeutic plasma exchange (TPE). Despite TPE, approximately 10% of patients still die, presumably from cardiac ischemia. We sought clinical or laboratory parameters associated with death by reviewing the records of all patients hospitalized with acquired TTP in our institution for 10 years, and collect demographics and results for hemoglobin, platelet count, creatinine, lactate dehydrogenase, transaminases, total bilirubin, creatinine kinase (CK), CK-MB, and troponin I. Sixty-eight patients were admitted 88 times, and 11 died. Survivors and non survivors were similar in terms of sex, ethnicity, thrombocytopenia, and degree of anemia at presentation, while the latter were older, had worse renal function and higher CK, CK-MB, and troponin I (univariate analysis). However, only troponin I remained significant on multivariate analyses. We propose that patients with TTP should be monitored with troponin I to detect significant myocardial ischemia that could predict death despite TPE. PMID- 27717012 TI - Histone deacetylase inhibitors for cancer therapy: An evolutionarily ancient resistance response may explain their limited success. AB - Histone deacetylase inhibitors (HDACi) are in clinical trials against a variety of cancers. Despite early successes, results against the more common solid tumors have been mixed. How is it that so many cancers, and most normal cells, tolerate the disruption caused by HDACi-induced protein hyperacetylation? And why are a few cancers so sensitive? Here we discuss recent results showing that human cells mount a coordinated transcriptional response to HDACi that mitigates their toxic effects. We present a hypothetical signaling system that could trigger and mediate this response. To account for the existence of such a response, we note that HDACi of various chemical types are made by a variety of organisms to kill or suppress competitors. We suggest that the resistance response in human cells is a necessary evolutionary consequence of exposure to environmental HDACi. We speculate that cancers sensitive to HDACi are those in which the resistance response has been compromised by mutation. Identifying such mutations will allow targeting of HDACi therapy to potentially susceptible cancers. Also see the video abstract here. PMID- 27717014 TI - Use of direct-acting agents for hepatitis C virus-positive kidney transplant candidates and kidney transplant recipients. AB - In some parts of the world, hepatitis C virus (HCV) infection remains a huge problem for kidney transplant candidates and kidney transplant (KT) recipients. Until 2 years ago, anti-HCV treatment for the general population relied on pegylated alpha-interferon plus ribavirin, but led to a sustained viral response (SVR) in <50% of cases. This treatment was contraindicated in KT patients because of acute-rejection issues and was poorly tolerated in patients with end-stage renal disease (ESRD). Over the last year, direct-acting antiviral agents (DAAs) have entered the market and are associated in the general population with a SVR of >90%, whatever the patient's HCV genotype. In KT patients, sofosbuvir-based therapy is associated with a SVR at nearly 100% in patients with a HCV genotype-1 infection, with almost no side effects and only mild interference with immunosuppressive drugs. Most HCV(+) patients with ESRD are genotype 1: in that setting, a recent study reported that the association of grazoprevir/elbasvir 100/50 mg/day led to a SVR of nearly 95% with very few side effects. Thus, it is concluded that DAAs can be safely used and lead to results in KT candidates and KT patients that are as good as those observed in the nonrenal population.

AB - OBJECTIVE: The role of B cells and the subgroup of IL-10 producing B cells, known to have a regulatory function, in patients following a haematopoietic stem cell transplant (alloSCT) has not been clearly understood to date. METHODS: We prospectively recruited 95 patients following an alloSCT and studied the B-cell reconstitution on days 30, 90 and 150. Regulatory B10 cells could be analysed in 22 consecutively recruited patients on day 30 post-transplant. RESULTS: The total B-cell percentages in transplant recipients (median 0.33; range 0.01-5.9) were significantly reduced than the controls (P = 0.0001) and constituted predominantly of transitional CD24high CD38high B cells. Regulatory B10 cells could be analysed in 22 consecutively recruited patients on day 30 post transplant. The percentages of B10 cells (median 1.35; 0.0-4.5) were significantly reduced in the transplant recipients in comparison with the control cohort (P < 0.0001). Interestingly, the percentages of B10 cells in patients with acute GvHD (median 1.7; 0.33-4.5) were significantly higher than those without GvHD (median 0.7; 0-1.9) (P = 0.0003). CONCLUSION: This is the first report demonstrating B10 cells in stem cell transplant recipients in the early post alloSCT (30 d) period. Our data suggest a possible role for B10 cells in the pathophysiology of acute GvHD. Further longitudinal studies are warranted to understand the implications of our findings. PMID- 27717017 TI - Five-year follow-up after live donor nephrectomy - cross-sectional and longitudinal analysis of a prospective cohort within the era of extended donor eligibility criteria. AB - To establish the outcome of live kidney donors 5 years after donation, we investigated the risk for progressive renal function decline and quality of life (QoL). Data on estimated glomerular filtration rate (eGFR), creatinine, hypertension, QoL and survival were assessed in a prospective cohort of 190 donors, who donated between 2008 and 2010. Data were available for >90%. The mean age predonation was 52.8 +/- 11.5 years, 30 donors having pre-existent hypertension. The mean follow-up was 5.1 +/- 0.9 years. Eight donors had died due to non-donation-related causes. After 5 years, the mean eGFR was 60.2 (95% CI 58.7-62.7) ml/min/1.73 m2 , with a median serum creatinine of 105.1 (95% CI 102.5 107.8) MUmol/l. eGFR decreased to 33.6% and was longitudinally lower among men than women and declining with age (P < 0.001), without any association on QoL. Donors with pre-existent and new-onset hypertension demonstrated no progressive decline of renal function overtime compared to nonhypertensives. No donors were found with proteinuria, microalbuminuria or at risk for end-stage renal disease. After an initial decline postdonation, renal function remained unchanged overtime. Men and ageing seem to affect renal function overtime, while decreased renal function did not affect QoL. These data support further stimulation of living kidney donation programmes as seen from the perspective of donor safety.

PMID- 27717019 TI - Lipid profile in patients with androgenetic alopecia: a meta-analysis. AB - BACKGROUND: Many studies have reported that androgenetic alopecia (AGA) might be a risk factor for cardiovascular disorders, and the association of AGA with dyslipidaemia has been studied. However, the results were controversial and previous meta-analyses had several critical limitations. OBJECTIVE: We performed a meta-analysis to clarify whether AGA patients have abnormal lipid profiles. METHODS: A literature search was performed using the MEDLINE, EMBASE, The Cochrane Library and KOREA MED databases. RESULTS: We pooled 19 observational studies and performed a meta-analysis to compare serum total cholesterol, serum triglyceride (TG), low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) and the cholesterol levels between AGA and control groups. The serum total cholesterol, TG and LDL cholesterol levels were significantly higher in the AGA group than in the control group, and the standardized mean differences were 0.377 (95% confidence interval [CI]: 0.182-0.572, P < 0.001), 0.426 (95% CI: 0.164-0.688, P = 0.001) and 0.450 (95% CI: 0.171-0.728, P = 0.002) respectively. In addition, HDL cholesterol level was significantly lower in the AGA group than in the control group, and the standardized mean difference was -0.248 (95% CI: 0.472 to -0.023, P = 0.030). CONCLUSIONS: AGA patients showed statistically significant abnormal lipid profiles, and this might partly explain the association between AGA and cardiovascular diseases. PMID- 27717020 TI - Does nitrogen affect the interaction between a native hemiparasite and its native or introduced leguminous hosts? AB - Associations between plants and nitrogen (N)-fixing rhizobia intensify with decreasing N supply and come at a carbon cost to the host. However, what additional impact parasitic plants have on their leguminous hosts' carbon budget in terms of effects on host physiology and growth is unknown. Under glasshouse conditions, Ulex europaeus and Acacia paradoxa either uninfected or infected with the hemiparasite Cassytha pubescens were supplied (high nitrogen (HN)) or not (low nitrogen (LN)) with extra N. The photosynthetic performance and growth of the association were measured. Cassytha pubescens significantly reduced the maximum electron transport rates and total biomass of U. europaeus but not those of A. paradoxa, regardless of N. Infection significantly decreased the root biomass of A. paradoxa only at LN, while the significant negative effect of infection on roots of U. europaeus was less severe at LN. Infection had a significant negative impact on host nodule biomass. Ulex europaeus supported significantly greater parasite biomass (also per unit host biomass) than A. paradoxa, regardless of N. We concluded that rhizobia do not influence the effect of a native parasite on overall growth of leguminous hosts. Our results suggest that C. pubescens will have a strong impact on U. europaeus but not A. paradoxa, regardless of N in the field.

PMID- 27717024 TI - Plants are less negatively affected by flooding when growing in species-rich plant communities. AB - Flooding is expected to increase in frequency and severity in the future. The ecological consequences of flooding are the combined result of species-specific plant traits and ecological context. However, the majority of past flooding research has focused on individual model species under highly controlled conditions. An early summer flooding event in a grassland biodiversity experiment in Jena, Germany, provided the opportunity to assess flooding responses of 60 grassland species in monocultures and 16-species mixtures. We examined plant biomass, species-specific traits (plant height, specific leaf area (SLA), root aerenchyma, starch content) and soil porosity. We found that, on average, plant species were less negatively affected by the flood when grown in higher-diversity plots in July 2013. By September 2013, grasses were unaffected by the flood regardless of plant diversity, and legumes were severely negatively affected regardless of plant diversity. Plants with greater SLA and more root aerenchyma performed better in September. Soil porosity was higher in higher-diversity plots and had a positive effect on plant performance. As floods become more frequent and severe in the future, growing flood-sensitive plants in higher-diversity communities and in soil with greater soil aeration may attenuate the most negative effects of flooding. PMID- 27717026 TI - Epidemiology of bloodstream infections in patients with myeloma receiving current era therapy. AB - BACKGROUND: Bloodstream infections (BSIs) are a significant complication of treatment for multiple myeloma (MM). The objective of this study was to define the epidemiology of BSI with current era MM treatment regimens, including immunomodulatory drugs, proteasome inhibitors and autologous haematopoietic stem cell transplantation (ASCT). METHODS: Clinical and microbiology records of patients with MM diagnosed between 2008 and 2012 were reviewed using a standardised tool to capture patient demographics, myeloma characteristics and BSI characteristics (type, severity, outcomes). Conditional risk set modelling was used to determine clinical predictors of BSI. RESULTS: Of 199 studied patients, 71 (35.6%) had confirmed BSI (98 infection episodes). Peak incidence was 65.1 infections/100 patient-years at 4-6 months following MM diagnosis with a late peak at 64-66 months. Gram-positive pathogens were responsible for the majority (54.5%) of infections during induction, whilst gram-negative pathogens were responsible for the majority (57.7%) of infections during disease progression. Overall, Escherichia coli was the most frequently identified pathogen. Streptococcus pneumoniae comprised 6.1% of all BSIs at a median of 7.5 months following MM diagnosis. Highest rates of ICU admission (23.1%) and mortality (11.5%) were seen with BSIs in patients with progressive disease. Recent ASCT was independently associated with increased BSI risk (HR 3.09, P = 0.05). CONCLUSIONS: Treatment of progressive disease is a high-risk period for infection, evidenced by high proportions of BSI due to gram-negative pathogens and S. pneumoniae. Targeted evaluation of preventative strategies (prophylaxis, vaccination) to reduce morbidity and mortality during this period is required. PMID- 27717025 TI - Determining donor-specific antibody C1q-binding ability improves the prediction of antibody-mediated rejection in human leucocyte antigen-incompatible kidney transplantation. AB - Detrimental impact of preformed donor-specific antibodies (DSAs) against human leucocyte antigens on outcomes after kidney transplantation are well documented, however, the value of their capacity to bind complement for predicting antibody mediated rejection (AMR) and graft survival still needs to be confirmed. We aimed to study DSA characteristics (strength and C1q binding) that might distinguish harmful DSA from clinically irrelevant ones. We retrospectively studied 60 kidney transplanted patients with preformed DSA detected by single antigen bead (SAB) assays (IgG and C1q kits), from a cohort of 517 kidney graft recipients (124 with detectable anti-HLA antibodies). Patients were divided into DSA strength (MFI < vs. >= 15 000) and C1q-binding ability. AMR frequency was high (30%) and it increased with DSA strength (P = 0.002) and C1q+ DSA (P < 0.001). The performance of DSA C1q-binding ability as a predictor of AMR was better than DSA strength (diagnostic odds ratio 16.3 vs. 6.4, respectively). Furthermore, a multivariable logistic regression showed that C1q+ DSA was a risk factor for AMR (OR = 16.80, P = 0.001), while high MFI DSAs were not. Graft survival was lower in high MFI C1q+ DSA in comparison with patients with C1q- high or low MFI DSA (at 6 years, 38%, 83% and 80%, respectively; P = 0.001). Both DSA strength and C1q-binding ability assessment seem valuable for improving pretransplant risk assessment. Since DSA C1q-binding ability was a better predictor of AMR and correlated with graft survival, C1q-SAB may be a particularly useful tool.

PMID- 27717030 TI - The Epstein-Barr virus DNA load in the peripheral blood of transplant recipients does not accurately reflect the burden of infected cells. AB - Transplant recipients frequently exhibit an increased Epstein-Barr virus (EBV) load in the peripheral blood. Here, we quantitated the EBV-infected cells in the peripheral blood of these patients and defined the mode of viral infection, latent or lytic. These data indicated that there is no strong correlation between the number of infected cells and the EBV load (EBVL). This can be explained by a highly variable number of EBV copies per infected cell and by lytic replication in some cells. The plasma of these patients did not contain any free infectious viruses, but contained nevertheless EBV DNA, sometimes in large amounts, that probably originates from cell debris and contributed to the total EBVL. Some of the investigated samples carried a highly variable number of infected cells in active latency, characterized by an expression of the Epstein-Barr nuclear antigens (EBNA2) protein. However, a third of the samples expressed neither EBNA2 nor lytic proteins. Patients with an increased EBVL represent a heterogeneous group of patients whose infection cannot be characterized by this method alone. Precise characterization of the origin of an increased EBVL, in particular, in terms of the number of EBV-infected cells, requires additional investigations including the number of EBV-encoded small RNA-positive cells.

AB - Compared with the dominant aromatic conjugated materials, photovoltaic applications of their quinoidal counterparts featuring rigid and planar molecular structures have long been unexplored despite their narrow optical bandgaps, large absorption coefficients, and excellent charge-transport properties. The design and synthesis of dithienoindophenine derivatives (DTIPs) by stabilizing the quinoidal resonance of the parent indophenine framework is reported here. Compared with the ambipolar indophenine derivatives, DTIPs with the fixed molecular configuration are found to be p-type semiconductors exhibiting excellent unipolar hole mobilities up to 0.22 cm2 V-1 s-1 , which is one order of magnitude higher than that of the parent IP-O and is even comparable to that of QQT(CN)4-based single-crystal field-effect transistors (FET). DTIPs exhibit better photovoltaic performance than their aromatic bithieno[3,4-b]thiophene (BTT) counterparts with an optimal power-conversion efficiency (PCE) of 4.07 %.

AB - Study of the kinetics of intramolecular aryl ether C-O bond cleavage by Ni was facilitated by access to a family of metal complexes supported by diphosphines with pendant aryl-methyl ethers. The nature of the aryl substituents was found to have little effect on the rate of cleavage. In contrast, soluble Lewis acidic additives accelerate the aryl ether cleavage dramatically. The effect of AlMe3 was studied in detail, and showed an increase in rate by several orders of magnitude. Low temperature NMR spectroscopy studies demonstrate quantitative coordination of ether to Al. From the Lewis acid-bound precursor, the activation parameters for ether cleavage are significantly lower. These findings provide a mechanistic basis for milder catalyst design for the activation of strong bonds. PMID- 27717038 TI - N-Heterocyclic Olefin-Carbon Dioxide and -Sulfur Dioxide Adducts: Structures and Interesting Reactivity Patterns. AB - Depending on the amount of methanol present in solution, CO2 adducts of N heterocyclic carbenes (NHCs) and N-heterocyclic olefins (NHOs) have been found to be in fully reversible equilibrium with the corresponding methyl carbonate salts [EMIm][OCO2 Me] and [EMMIm][OCO2 Me]. The reactivity pattern of representative 1 ethyl-3-methyl-NHO-CO2 adduct 4 has been investigated and compared with the corresponding NHC-CO2 zwitterion: The protonation of 4 with HX led to the imidazolium salts [NHO-CO2 H][X], which underwent decarboxylation to [EMMIm][X] in the presence of nucleophilic catalysts. NHO-CO2 zwitterion 4 can act as an efficient carboxylating agent towards CH acids such as acetonitrile. The [EMMIm] cyanoacetate and [EMMIm]2 cyanomalonate salts formed exemplify the first C-C bond forming carboxylation reactions with NHO-activated CO2 . The reaction of the free NHO with dimethyl carbonate selectively led to methoxycarbonylated NHO, which is a perfect precursor for the synthesis of functionalized ILs [NHO-CO2 Me][X]. The first NHO-SO2 adduct was synthesized and structurally characterized; it showed a similar reactivity pattern, which allowed the synthesis of imidazolium methyl sulfites upon reaction with methanol. PMID- 27717037 TI - Early detection of human glioma sphere xenografts in mouse brain using diffusion MRI at 14.1 T. AB - Glioma models have provided important insights into human brain cancers. Among the investigative tools, MRI has allowed their characterization and diagnosis. In this study, we investigated whether diffusion MRI might be a useful technique for early detection and characterization of slow-growing and diffuse infiltrative gliomas, such as the proposed new models, LN-2669GS and LN-2540GS glioma sphere xenografts. Tumours grown in these models are not visible in conventional T2 weighted or contrast-enhanced T1 -weighted MRI at 14.1 T. Diffusion-weighted imaging and diffusion tensor imaging protocols were optimized for contrast by exploring long diffusion times sensitive for probing the microstructural alterations induced in the normal brain by the slow infiltration of glioma sphere cells. Compared with T2 -weighted images, tumours were properly identified in their early stage of growth using diffusion MRI, and confirmed by localized proton MR spectroscopy as well as immunohistochemistry. The first evidence of tumour presence was revealed for both glioma sphere xenograft models three months after tumour implantation, while no necrosis, oedema or haemorrhage were detected either by MRI or by histology. Moreover, different values of diffusion indices, such as mean diffusivity and fractional anisotropy, were obtained in tumours grown from LN-2669GS and LN-2540GS glioma sphere lines. These observations highlighted diverse tumour microstructures for both xenograft models, which were reflected in histology. This study demonstrates the ability of diffusion MRI techniques to identify and investigate early stages of slow-growing, invasive tumours in the mouse brain, thus providing a potential imaging biomarker for early detection of tumours in humans. PMID- 27717040 TI - Stability and Unimolecular Reactivity of Palladate(II) Complexes [Ln PdR3 ]- (L=Phosphine, R=Organyl, n=0 and 1). AB - The reduction of PdII precatalysts to catalytically active Pd0 species is a key step in many palladium-mediated cross-coupling reactions. Besides phosphines, the stoichiometrically used organometallic reagents can afford this reduction, but do so in a poorly understood way. To elucidate the mechanism of this reaction, we have treated solutions of Pd(OAc)2 and a phosphine ligand L in tetrahydrofuran with RMgCl (R=Ph, Bn, Bu) as well as other organometallic reagents. Analysis of these model systems by electrospray- ionization mass spectrometry found palladate(II) complexes [Ln PdR3 ]- (n=0 and 1), thus pointing to the occurrence of transmetallation reactions. Upon gas-phase fragmentation, the [Ln PdR3 ]- anions preferentially underwent a reductive elimination to yield Pd0 species. The sequence of the transmetallation and reductive elimination, thus, constitutes a feasible mechanism for the reduction of the Pd(OAc)2 precatalyst. Other species of interest observed include the PdIV complex [PdBn5 ]- , which did not fragment via a reductive elimination but lost BnH instead.

AB - BACKGROUND: Prenatal alcohol exposure (PAE) in animal models results in excitatory-inhibitory (E/I) imbalance in neocortex due to alterations in the GABAergic interneuron (IN) differentiation and migration. Thus, E/I imbalance is a potential cause for intellectual disability in individuals with fetal alcohol spectrum disorder (FASD), but whether ethanol (EtOH) changes glutamatergic and GABAergic IN specification during human development remains unknown. Here, we created a human cellular model of PAE/FASD and tested the hypothesis that EtOH exposure during differentiation of human pluripotent stem cell-derived neurons (hPSNs) would cause the aberrant production of glutamatergic and GABAergic neurons, resulting in E/I imbalance. METHODS: We applied 50 mM EtOH daily to differentiating hPSNs for 50 days to model chronic first-trimester exposure. We used quantitative polymerase chain reaction, immunocytochemical, and electrophysiological analysis to examine the effects of EtOH on hPSN specification and functional E/I balance. RESULTS: We found that EtOH did not alter neural induction nor general forebrain patterning and had no effect on the expression of markers of excitatory cortical pyramidal neurons. In contrast, our data revealed highly significant changes to levels of transcripts involved with IN precursor development (e.g., GSX2, DLX1/2/5/6, NR2F2) as well as mature IN specification (e.g., SST, NPY). Interestingly, EtOH did not affect the number of GABAergic neurons generated nor the frequency or amplitude of miniature excitatory and inhibitory postsynaptic currents. CONCLUSIONS: Similar to in vivo rodent studies, EtOH significantly and specifically altered the expression of genes involved with IN specification from hPSNs, but did not cause imbalances of synaptic excitation-inhibition. Thus, our findings corroborate previous studies pointing to aberrant neuronal differentiation as an underlying mechanism of intellectual disability in FASD. However, in contrast to rodent binge models, our chronic exposure model suggests possible compensatory mechanisms that may cause more subtle defects of network processing rather than gross alterations in total E/I balance.

AB - The present work aimed at analyzing the effects of melatonin on scar formation after spinal cord injury (SCI). Upregulation of reactive astrocyte under SCI pathological conditions has been presented in several studies. It has been proved that the crucial factor in triggering this upregulation is proinflammatory cytokines. Moreover, scar formation is an important barrier to axonal regeneration through the lesion area. Melatonin plays an important role in reducing inflammation, but its effects on scar formation in the injured spinal cord remain unknown. Hence, we used the model of severe crush injury in mice to investigate the effects of melatonin on scar formation. Mice were randomly separated into four groups; SCI, SCI+Melatonin 1 (single dose), SCI+Melatonin 14 (14 daily doses), and control. Melatonin was administered by intraperitoneal injection (10 mg/kg) after injury. Immunohistochemical analysis, Western blot, and behavioral evaluation were used to explore the effects of melatonin after SCI for 14 days. The melatonin-treated mice presented higher expression of neuronal markers (P < 0.001). Remarkably, the inflammatory response appeared to be greatly reduced in the SCI+Melatonin 14 group (P < 0.001), which also displayed less scar formation (P < 0.05). These findings suggest that melatonin inhibits scar formation by acting on inflammatory cytokines after SCI. Overall, our results suggest that melatonin is a promising treatment strategy after SCI that deserves further investigation. (c) 2016 Wiley Periodicals, Inc. PMID- 27717043 TI - Microscopic DTI accurately identifies early glioma cell migration: correlation with multimodal imaging in a new glioma stem cell model. AB - Monitoring glioma cell infiltration in the brain is critical for diagnosis and therapy. Using a new glioma Glio6 mouse model derived from human stem cells we show how diffusion tensor imaging (DTI) may predict glioma cell migration/invasion. In vivo multiparametric MRI was performed at one, two and three months of Glio6 glioma growth (Glio6 (n = 6), sham (n = 3)). This longitudinal study reveals the existence of a time window to study glioma cell/migration/invasion selectively. Indeed, at two months only Glio6 cell invasion was detected, while tumor mass formation, edema, blood-brain barrier leakage and tumor angiogenesis were detected later, at three months. To robustly confirm the potential of DTI for detecting glioma cell migration/invasion, a microscopic 3D-DTI (80 MUm isotropic spatial resolution) technique was developed and applied to fixed mouse brains (Glio6 (n = 6), sham (n = 3)). DTI changes were predominant in the corpus callosum (CC), a known path of cell migration. Fractional anisotropy (FA) and perpendicular diffusivity (D? ) changes derived from ex vivo microscopic 3D-DTI were significant at two months of tumor growth. In the caudate putamen an FA increase of +38% (p < 0.001) was observed, while in the CC a - 28% decrease in FA (p < 0.005) and a + 95% increase in D? (p < 0.005) were observed. In the CC, DTI changes and fluorescent Glio6 cell density obtained by two-photon microscopy in the same brains were correlated (p < 0.001, r = 0.69), validating FA and D? as early quantitative biomarkers to detect glioma cell migration/invasion. The origin of DTI changes was assessed by electron microscopy of the same tract, showing axon bundle disorganization. During the first two months, Glio6 cells display a migratory phenotype without being associated with the constitution of a brain tumor mass. This offers a unique opportunity to apply microscopic 3D-DTI and to validate DTI parameters FA and D? as biomarkers for glioma cell invasion. PMID- 27717041 TI - Effects of Gabra2 Point Mutations on Alcohol Intake: Increased Binge-Like and Blunted Chronic Drinking by Mice. AB - BACKGROUND: Alcohol use disorders are associated with single-nucleotide polymorphisms in GABRA2, the gene encoding the GABAA receptor alpha2-subunit in humans. Deficient GABAergic functioning is linked to impulse control disorders, intermittent explosive disorder, and to drug abuse and dependence, yet it remains unclear whether alpha2-containing GABAA receptor sensitivity to endogenous ligands is involved in excessive alcohol drinking. METHODS: Male wild-type (Wt) C57BL/6J and point-mutated mice rendered insensitive to GABAergic modulation by benzodiazepines (BZD; H101R), allopregnanolone (ALLO) or tetrahydrodeoxycorticosterone (THDOC; Q241M), or high concentrations of ethanol (EtOH) (S270H/L277A) at alpha2-containing GABAA receptors were assessed for their binge-like, moderate, or escalated chronic drinking using drinking in the dark, continuous access (CA) and intermittent access (IA) to alcohol protocols, respectively. Social approach by mutant and Wt mice in forced alcohol abstinence was compared to approach by EtOH-naive controls. Social deficits in forced abstinence were treated with allopregnanolone (0, 3.0, 10.0 mg/kg, intraperitoneal [i.p.]) or midazolam (0, 0.56, 1.0 mg/kg, i.p.). RESULTS: Mice with BZD-insensitive alpha2-containing GABAA receptors (H101R) escalated their binge-like drinking. Mutants harboring the Q241M point substitution in Gabra2 showed blunted chronic intake in the CA and IA protocols. S270H/L277A mutants consumed excessive amounts of alcohol but, unlike wild-types, they did not show forced abstinence-induced social deficits. CONCLUSIONS: These findings suggest a role for: (i) H101 in species-typical binge-like drinking, (ii) Q241 in escalated chronic drinking, and (iii) S270 and/or L277 in the development of forced abstinence-associated social deficits. Clinical findings report reduced BZD binding sites in the cortex of dependent patients; the present findings suggest a specific role for BZD-sensitive alpha2-containing receptors. In addition, amino acid residue 241 in Gabra2 is necessary for positive modulation and activation of GABAA receptors by ALLO and THDOC; we postulate that neurosteroid action on alpha2-containing receptor may be necessary for escalated chronic EtOH intake. PMID- 27717045 TI - Rim, Side Arms, and Cavity: Three Sites for the Recognition of Anions by Tetraazolium Resorcinarene Cavitands. AB - Two tetrabenzoimidazolium-resorcinarene cavitands were prepared and used for the recognition of chloride, bromide, iodide, cyanide, nitrate, perchlorate, hexanoate, benzenesulfonate, and p-toluenesulfonate. Binding affinities of the two cavitands were determined by 1 H NMR titration and computational analysis. The observed spectral changes were related to specific interaction sites, which were supported by the computational studies. In the case of the C2-H tetrabenzoimidazolium-resorcinarene, the recognition region of the inorganic anions and hexanoate was located at the rim of the cavitand, although chloride and bromide also interacted with the aromatic C-H bonds located between adjacent arms of the cavitand. By contrast, the recognition of the two anions with an aromatic ring (benzenesulfonate and p-toluenesulfonate) results from encapsulation of the aromatic part of the anions inside the hydrophobic cavity of the host. In the case of the C2-Me tetrabenzoimizazolium-resorcinarene receptor, the ability of the molecule to bind all inorganic anions and hexanoate was suppressed, but the receptor maintained its ability to strongly bind benzenesulfonate and p-toluenesulfonate. This is interpreted in terms of suppression of the ability of the cavitand to form hydrogen bonds at the rim of the molecule due to replacement of the C2-H proton by a methyl group, while the hydrophobic pocket of the molecule maintains its binding abilities. PMID- 27717046 TI - Superabsorbent, High Porosity, PAMPS-Based Hydrogels through Emulsion Templating. AB - Swell! Superabsorbent, mechanically robust, high-porosity hydrogels based on poly(2-acrylamido-2-methyl-1-propanesulfonic acid) have been successfully synthesized by templating within high internal phase emulsions (HIPEs). These hydrogel polyHIPEs (HG-PHs) exhibit unusually high uptakes of water and of artificial urine through structure- and crosslinking-dependent hydrogel-swelling driven void expansion. An HG-PH with 3.1 mmol g-1 of highly accessible sulfonic acid groups exhibits a 7 meq NaOH ion exchange capacity per gram polymer and rapid dye absorption. The highly swollen HG-PHs do not fail at compressive strains of up to 60%, they retain water and recover their shapes upon the removal of stress. Unusually, the dry hydrogels have relatively high compressive moduli and achieve relatively high stresses at 70% strain. PMID- 27717044 TI - Synthesis of Potent and Selective HDAC6 Inhibitors Bearing a Cyclohexane- or Cycloheptane-Annulated 1,5-Benzothiazepine Scaffold. AB - Selective inhibitors of histone deacetylase 6 (HDAC6) are an emerging class of pharmaceuticals due to the involvement of HDAC6 in different pathways related to neurodegenerative diseases, cancer, and immunology. Herein, the synthesis of ten new benzohydroxamic acids, constructed by employing the tetrahydrobenzothiazepine core as a privileged pharmacophoric unit, is described. This is the first report on the synthesis and isolation of octahydrodibenzothiazepines and octahydro-6H benzocycloheptathiazepines, which were then used to develop a new class of HDAC6 inhibitors. Evaluations of their HDAC-inhibiting activity resulted in the identification of cis-N-(4-hydroxycarbamoylbenzyl)-1,2,3,4,4a,5,11,11a octahydrodibenzo[b,e][1,4]thiazepine-10,10-dioxide and cis-N-(4 hydroxycarbamoylbenzyl)-7-trifluoromethyl-1,2,3,4,4a,5,11,11a octahydrodibenzo[b,e][1,4]thiazepine-10,10-dioxide as highly potent and selective HDAC6 inhibitors with activity in the low nanomolar range, which also show excellent selectivity on the enzymatic and cellular levels. Furthermore, four promising inhibitors were subjected to an Ames fluctuation assay, which revealed no mutagenic effects associated with these structures. PMID- 27717047 TI - Activation of Aromatic C-C Bonds of 2,2'-Bipyridine Ligands. AB - 4,4'-Disubstituted-2,2'-bipyridine ligands coordinated to MoII and ReI cationic fragments become dearomatized by an intramolecular nucleophilic attack from a deprotonated N-alkylimidazole ligand in cis disposition. The subsequent protonation of these neutral complexes takes place on a pyridine carbon atom rather than at nitrogen, weakening an aromatic C-C bond and affording a dihydropyridyl moiety. Computational calculations allowed for the rationalization of the formation of the experimentally obtained products over other plausible alternatives.

AB - Two different nonfullerene acceptors and one copolymer are used to fabricate ternary organic solar cells (OSCs).

This work provides a new approach to fabricate high performance OSCs. PMID- 27717049 TI - Enantio- and Stereoselective Cyclopolymerization of Hexa-1,5-diene Catalyzed by Zirconium Complexes Possessing Optically Active Bis(phenolato) Ligands. AB - Enantio- and stereoselective cyclopolymerization of hexa-1,5-diene was achieved by enantiomerically pure dichloro zirconium(IV) pre-catalysts 2 possessing chiral [OSSO]-type bis(phenolate) ligands (-)-1 and (+)-1 in combination with dried methylaluminoxane (dMAO) as an activator. The corresponding activities were recorded with quite high values up to 1,960 g mmol(2)-1 h-1 , which are extremely larger than those of the related complexes. The microstructure analysis for the PMCPs furnished by pre-catalysts (Lambda,S,S)-2 and (Delta,R,R)-2 showed good isotacticity factors (alpha = 75-78%) and relatively high proportions of trans cyclopentane rings (sigma = 14-21%). These enantiomeric PMCPs exhibited large specific optical rotations ([alpha]D = +28 to +32 degrees from (Lambda,S,S)-2, 26 to -34 degrees from (Delta,R,R)-2). PMID- 27717050 TI - Transient and persistent behavioral and molecular changes in primiparous female Wistar rats. AB - Motherhood brings about a multitude of behavioral and physiological changes in dams and some of these persist until after weaning. We studied behavioral changes associated with reproductive experience at lactating day (LD)8, at weaning (LD21), and 28 days post-weaning (PW28) compared to nulliparous (NP) females. Furthermore, in another cohort of animals, we quantified mRNA expression of five target genes known to be associated with maternal experience: arginin vasopressin(Avp) and its 1A receptor(Avpr1a), oxytocin(Oxt) and its receptor(Oxtr), and corticotropin-releasing hormone(Crh) in three key maternal region: the medial preoptic area (MPOA), bed nucleus of the stria terminalis (BNST) and paraventricular hypothalamic nucleus(PVN). Although dams were slightly less anxious than NP at LD8, this effect did not persist at LD21 and PW28. No differences in social preference were found between the four groups. In the maternal responsiveness test (MRT), LD8 and LD21 dams were immediately responsive to pups whereas NP largely avoided the pups throughout 12-day period. PW28 females were significantly more responsive to pups than NP females, but less than LD8 and LD21 females. The mRNA expression of Avp in the PVN, Avpr1a in the BNST and Oxtr in the MPOA and BNST was increased, whereas mRNA expression of Avpr1a was reduced in the PVN, at LD8 compared to NP. Although Oxtr in the BNST and Avp in the PVN were still somewhat (non-significantly) increased at LD21, all levels of gene expression had normalized at PW28. Our results emphasize the transient nature of these behavioral and molecular adaptations, except for a persistent up regulation of maternal responsiveness.

PMID- 27717053 TI - Coupling of D2R Short but not D2R Long receptor isoform to the Rho/ROCK signaling pathway renders striatal neurons vulnerable to mutant huntingtin. AB - Huntington's disease, an inherited neurodegenerative disorder, results from abnormal polyglutamine extension in the N-terminal region of the huntingtin protein. This mutation causes preferential degeneration of striatal projection neurons. We previously demonstrated, in vitro, that dopaminergic D2 receptor stimulation acted in synergy with expanded huntingtin to increase aggregates formation and striatal death through activation of the Rho/ROCK signaling pathway. In vivo, in a lentiviral-mediated model of expanded huntingtin expression in the rat striatum, we found that the D2 antagonist haloperidol protects striatal neurons against expanded huntingtin-mediated toxicity. Two variant transcripts are generated by alternative splicing of the of D2 receptor gene, the D2R-Long and the D2R-Short, which are thought to play different functional roles. We show herein that overexpression of D2R-Short, but not D2R Long in cell lines is associated with activation of the RhoA/ROCK signaling pathway. In striatal neurons in culture, the selective D2 agonist Quinpirole triggers phosphorylation of cofilin, a downstream effector of ROCK, which is abrogated by siRNAs that knockdown both D2R-Long and D2R-Short, but not by siRNAs targeting D2R-Long alone. Aggregate formation and neuronal death induced by expanded huntingtin, were potentiated by Quinpirole. This D2 agonist-mediated effect was selectively inhibited by the siRNA targeting both D2R-Long and D2R Short but not D2R-Long alone. Our data provide evidence for a specific coupling of D2R-Short to the RhoA/ROCK/cofilin pathway, and its involvement in striatal vulnerability to expanded huntingtin. A new route for targeting Rho-ROCK signaling in Huntington's disease is unraveled with our findings. PMID- 27717055 TI - Polymer Capsules for Plaque-Targeted In Vivo Delivery. PMID- 27717054 TI - Alpha-power modulation reflects the balancing of task requirements in a selective attention task. AB - Recent research has related the orienting of selective attention to the lateralization of posterior EEG alpha power (~8 to 12 Hz). Typically, alpha power decreases over the side of the head contralateral to the cued side of space. However, it is not clear how this lateralization affects behavior. We recorded EEG from 20 participants while they performed a cued visual discrimination task under three different response-deadline conditions to investigate the effect of alpha-power modulation on behavioral performance in more detail. Although all participants benefited from the cue behaviorally and adjusted their performance according to the response deadlines, we found the cue-related alpha-power modulation to depend on the general alpha-power level at baseline: Only participants with high baseline alpha power showed significant cue-related alpha power lateralization that was, however, strikingly similar across response deadline conditions. On the other hand, participants with low alpha power at baseline did not show any lateralization, but adjusted their alpha levels according to the response-deadline instructions and, more importantly, showed a stronger influence of the task instructions on behavioral performance and adapted their response accuracies to the task requirements more flexibly. These findings challenge the often-assumed role of alpha-power lateralization for attentional deployment. While alpha power seems to be related to behavioral performance and the orienting of attention, this relationship is rather complex and, at least under the current task requirements, the general alpha-power state seems to be more strongly related to behavioral performance (in our case, the flexible adjustment to task requirements) than the cue-related lateralization. PMID- 27717056 TI - Functionalization of Planet-Satellite Nanostructures Revealed by Nanoscopic Localization of Distinct Macromolecular Species. AB - The development of a straightforward method is reported to form hybrid polymer/gold planet-satellite nanostructures (PlSNs) with functional polymer. Polyacrylate type polymer with benzyl chloride in its backbone as a macromolecular tracer is synthesized to study its localization within PlSNs by analyzing the elemental distribution of chlorine. The functionalized nanohybrid structures are analyzed by scanning transmission electron microscopy, electron energy loss spectroscopy, and spectrum imaging. The results show that the RAFT (reversible addition-fragmentation chain transfer) polymers' sulfur containing end groups are colocalized at the gold cores, both within nanohybrids of simple core-shell morphology and within higher order PlSNs, providing microscopic evidence for the affinity of the RAFT group toward gold surfaces. PMID- 27717057 TI - Open access follow-up care for early breast cancer: a randomised controlled quality of life analysis. AB - This study evaluated the acceptability of a supportive model of follow-up. One hundred and twelve women recovering from breast cancer were randomised to receive standard breast clinic aftercare (Control n = 56) or on demand by open access aftercare by breast care nurses (Intervention n = 56). Participants attended a support-based psycho-educational programme delivered in four half-day group sessions. Three quality of life questionnaires (EORTC QLQ-C30, QLQ-BR23, HADS) were administered at baseline and 6-monthly intervals for 2 years. Multilevel linear regression modelling methods were used for evaluation. Age was found to be a statistically significant predictor of quality of life in several sub-scales. Increasing age was negatively associated with sexual functioning, systematic therapy side effects and physical functioning, and positively associated with future perspective. Aftercare assignment was not found to be a statistically significant predictor. Women treated for early breast cancer were not disadvantaged by allocation to the open access supportive care model in terms of quality of life experienced. The model for follow-up was demonstrated to be a feasible alternative to routinised hospital-based follow-up and adds to the evidence for stratified follow-up for low-risk cancer patients, incorporating self-management education. Stratified follow-up pathways are viewed as a preferable approach. PMID- 27717058 TI - Pro-Life Arguments Against Infanticide and Why they are Not Convincing. AB - Alberto Giubilini and Francesca Minerva's controversial article 'After-Birth Abortion: Why Should the Baby Live?' has received a lot of criticism since its publishing. Part of the recent criticism has been made by pro-life philosopher Christopher Kaczor, who argues against infanticide in his updated book 'Ethics of Abortion'. Kaczor makes four arguments to show where Giubilini and Minerva's argument for permitting infanticide goes wrong. In this article I argue that Kaczor's arguments, and some similar arguments presented by other philosophers, are mistaken and cannot show Giubilini and Minerva's view to be flawed. I claim that if one wants to reject the permissibility of infanticide, one must find better arguments for doing so. PMID- 27717059 TI - Human COL5A1 polymorphisms and quadriceps muscle-tendon mechanical stiffness in vivo. AB - NEW FINDINGS: What is the central question of the study? Do COL5A1 gene variants, previously reported to have diminished transcript stability, manifest in physiological phenotypes of quadriceps muscle-tendon contractile properties and mechanical stiffness in humans? What is the main finding and its importance? COL5A1 gene variants influence mechanical stiffness, not seeming to affect low level contractile properties in humans. Functional differences in COL5A1 manifest during moderate- to high-level contractions. Polymorphisms of the collagen type V alpha 1 chain (COL5A1) gene are purported to influence mechanical properties of collagenous tissues. Our purpose was to assess musculotendinous contractile properties of the quadriceps in relationship to the genetic influence of mechanical stiffness. Eighty recreationally active males (aged 19-31 years) were assessed for the presence of three genetic polymorphisms associated with COL5A1 mRNA stability (rs4919510, rs1536482 and rs12722). Genotypes were determined using real-time PCR. Stiffness and contractile properties of the knee musculotendinous complex were assessed by maximal isometric voluntary contractions, ramp isometric voluntary contractions, electrically stimulated contractile events and ultrasonography. All genotype groups were able to activate their knee extensors fully (>97%) as assessed by the interpolated twitch technique and presented no differences in muscle-tendon contractile properties at low submaximal contraction intensities. For the quadriceps muscle-tendon at moderate ramp contractions of 50 and 60% maximal voluntary contraction, the rs12722 CT and TT genotypes had ~30% greater mean stiffness. The rs1536482 AG and GG genotypes showed a similar trend, but did not achieve statistical significance. Variants of the COL5A1 gene seem to influence quadriceps muscle tendon stiffness but do not affect low-level contractile properties. PMID- 27717060 TI - Ultrafast Preparation of AIE-Active Fluorescent Organic Nanoparticles via a "One Pot" Microwave-Assisted Kabachnik-Fields Reaction. AB - The development of effective strategies for fabrication of fluorescent organic nanoparticles (FONs) with an aggregation-induced emission (AIE) feature has an important impact on the biomedical applications of these AIE-active FONs. In the current work, an ultrafast strategy for fabricating AIE-active FONs is developed through a "one-pot" microwave-assisted, catalysts-free, and solvent-free Kabachnik-Fields (KF) reaction for the first time. It is demonstrated that such organophosphorous-containing AIE-active block polymers can be synthesized within 2 min under air atmosphere through the microwave-assisted KF reaction. These polymers show amphiphilic properties and can self-assemble into mPEG-CHO-Phe-NH2 DEP FONs, which display high water dispersibility and desirable optical properties. Biological evaluation results suggest that the mPEG-CHO-Phe-NH2 -DEP FONs exhibit low toxicity and are potential for biological imaging applications. More importantly, many other multifunctional AIE-active FONs can also be fabricated through the strategy described in this work owing to the universality of KF reaction. Besides, combined with the excellent properties of mPEG-CHO-Phe NH2 -DEP FONs, it is believed that such microwave-assisted KF reaction shall be an effective route for designing various AIE-active nanomaterials for different biomedical applications. PMID- 27717061 TI - A qualitative study of advanced nurse practitioners' use of physical assessment skills in the community: shifting skills across professional boundaries. AB - AIMS AND OBJECTIVES: To explore multiple perspectives on the use of physical assessment skills by advanced nurse practitioners in the UK. BACKGROUND: Physical assessment skills practices are embedded in advanced nursing practice roles in the UK. There is little evidence on how these skills are used by advanced nurse practitioners in the community. DESIGN: Case study. METHODS: A qualitative interpretative single-embedded case study of 22 participants from South of England. A framework method analysed interview data collected by the researcher between March-August 2013. Participants included nurses, doctors, nurse educators and managers. FINDINGS: Physical assessment skills education at universities is part of a policy shift to develop a flexible workforce in the UK. Shared physical assessment practices are less to do with role substitution and more about preparing practitioners with skills that are fit for purpose. Competence, capability and performance with physical assessment skills are an expectation of advanced nursing practice. CONCLUSIONS: These skills are used successfully by community advanced nurse practitioners to deliver a wide range of services in response to changing patient need. The introduction of physical assessment skills education to undergraduate professional preparation would create a firm foundation to develop these skills in postgraduate education. RELEVANCE TO CLINICAL PRACTICE: Physical assessment education prepares nurses with the clinical competencies to carry out healthcare reforms in the UK. Shared sets of clinical assessment competencies between disciplines have better outcomes for patients. Levels of assessment competence can depend on the professional attributes of individual practitioners. Unsupportive learning cultures can hinder professional development of advanced nursing practice. PMID- 27717062 TI - Body Dysmorphic Disorder: Contraindication or Ethical Justification for Female Genital Cosmetic Surgery in Adolescents. AB - Is Female Genital Cosmetic Surgery for an adolescent with Body Dysmorphic Disorder ever ethically justified? Cosmetic genital surgery (specifically labioplasty) for adolescent girls is one of the most ethically controversial forms of cosmetic surgery and Body Dysmorphic Disorder is typically seen as a contraindication for cosmetic surgery. Two key ethical concerns are (1) that Body Dysmorphic Disorder undermines whatever capacity for autonomy the adolescent has; and (2) even if there is valid parental consent, the presence of Body Dysmorphic Disorder means that cosmetic surgery will fail in its aims. In this article, we challenge, in an evidence-based way, the standard view that Body Dysmorphic Disorder is a contraindication for genital cosmetic surgery in adolescents. Our argument gathers together and unifies a substantial amount of disparate research in the context of an ethical argument. We focus on empirical questions about benefit and harm, because these are ethically significant. Answers to these questions affect the answer to the ethical question. We question the claim that there would be no benefit from surgery in this situation, and we consider possible harms that might be done if treatment is refused. For an adolescent with Body Dysmorphic Disorder, the most important thing may be to avoid harm. We find ourselves arguing for the ethical justifiability of cosmetic labioplasty for an adolescent with Body Dysmorphic Disorder, even though we recognize that it is a counter intuitive position. We explain how we reached our conclusion. PMID- 27717064 TI - High-order motor cortex in rats receives somatosensory inputs from the primary motor cortex via cortico-cortical pathways. AB - The motor cortex of rats contains two forelimb motor areas; the caudal forelimb area (CFA) and the rostral forelimb area (RFA). Although the RFA is thought to correspond to the premotor and/or supplementary motor cortices of primates, which are higher-order motor areas that receive somatosensory inputs, it is unknown whether the RFA of rats receives somatosensory inputs in the same manner. To investigate this issue, voltage-sensitive dye (VSD) imaging was used to assess the motor cortex in rats following a brief electrical stimulation of the forelimb. This procedure was followed by intracortical microstimulation (ICMS) mapping to identify the motor representations in the imaged cortex. The combined use of VSD imaging and ICMS revealed that both the CFA and RFA received excitatory synaptic inputs after forelimb stimulation. Further evaluation of the sensory input pathway to the RFA revealed that the forelimb-evoked RFA response was abolished either by the pharmacological inactivation of the CFA or a cortical transection between the CFA and RFA. These results suggest that forelimb-related sensory inputs would be transmitted to the RFA from the CFA via the cortico cortical pathway. Thus, the present findings imply that sensory information processed in the RFA may be used for the generation of coordinated forelimb movements, which would be similar to the function of the higher-order motor cortex in primates.

Bor1p belongs to the SLC4 family which controls bicarbonate exchange and pH regulation in animals as well as borate uptake in plants. The SLC4 family is more distantly related to members of the Amino acid-Polyamine-organoCation (APC) superfamily, which includes well studied transporters such as LeuT, Mhp1, AdiC, vSGLT, UraA, SLC26Dg. Their mechanism generally involves relative movements of two domains: a core domain that binds substrate and a gate domain that in many cases mediates dimerization. To shed light on conformational changes governing transport by the SLC4 family, we grew helical membrane crystals of Bor1p from Saccharomyces mikatae and determined a structure at ~6 A resolution using cryo electron microscopy. To evaluate the conformation of Bor1p in these crystals, a homology model was built based on the related anion exchanger from red blood cells (AE1). This homology model was fitted to the cryo-EM density map using the Molecular Dynamics (MD) Flexible Fitting method and then relaxed by all-atom MD simulation in explicit solvent and membrane. Mapping of water accessibility indicates that the resulting structure represents an inward-facing conformation. Comparisons of the resulting Bor1p model with the X-ray structure of AE1 in an outward-facing conformation, together with MD simulations of inward-facing and outward-facing Bor1p models, suggest rigid body movements of the core domain relative to the gate domain. These movements are consistent with the rocking bundle transport mechanism described for other members of the APC superfamily.

AB - One Health is a collaborative, transdisciplinary effort working locally, nationally, and globally to improve health for people, animals, plants, and the environment. The term is relatively new (from ~2003), and it is increasingly common to see One Health included by name in interinstitutional research partnerships, conferences, communications, and organizational frameworks, particularly those championed by the human health and veterinary medical communities. Environmental quality is arguably the least developed component within the One Health framework, but can be guided by expertise within the Society of Environmental Toxicology and Chemistry (SETAC). Despite SETAC's long history of tripartite (academic, government, business) interdisciplinary environmental science activities, the term "One Health" is seldom used in SETAC communications (i.e., many of SETAC's activities are guided by One Health, but it is called by other names in SETAC's journals, newsletters, and presentations). Accordingly, the objective of this Focus article is to introduce the One Health concept to the SETAC membership. The article discusses the origins, evolution, and utility of the One Health approach as an organizational framework and provides key examples of ways in which SETAC expertise can benefit the One Health community. The authors assert that One Health needs SETAC and, to be most effective, SETAC needs One Health. Given that One Health to date has focused too little on the environment, on ecosystems, and on contaminants, SETAC's constructive involvement in One Health presents an opportunity to accelerate actions that will ultimately better protect human and ecosystem health.

PMID- 27717069 TI - Carbon and nitrogen stable isotopic offsets between diet and hair/feces in captive chimpanzees. AB - RATIONALE: Estimation of the stable isotopic offsets between tissue and diet is important for dietary reconstructions. Although stable isotopic studies of chimpanzees (Pan troglodytes) are increasing, the isotopic offsets in chimpanzees have never been studied. In this study, the carbon and nitrogen stable isotopic offset values in hair and feces were measured for 13 captive chimpanzees for the first time. METHODS: All consumed food items and quantities were recorded for each individual for 1 week. Food samples were typically collected three times, hair was collected 3 weeks after the experimental week, and feces were collected ad libitum during the experimental week. The stable carbon and nitrogen isotope ratios were measured using elemental analyzer-isotope ratio mass spectrometry (EA IRMS). RESULTS: As the results of Monte Carlo analysis, the estimated carbon and nitrogen offsets between the hair and diet were +3.0 to +3.90/00 and +2.8 to +3.70/00, respectively, for the 95% confidence intervals (CIs). The 95% CIs of the carbon and nitrogen offset values between the feces and diet were -1.6 to 0.00/00 and +1.2 to +2.70/00, respectively. CONCLUSIONS: These offset values are generally consistent with those of the other primate species reported in previous studies. However, potential variations in the offset values due to dietary and physiological factors should be studied in detail in the future. Copyright (c) 2016 John Wiley & Sons, Ltd.

PMID- 27717073 TI - Migration and nutritional status of Tarahumara schoolchildren from Chihuahua State (Mexico). AB - OBJECTIVE: The Tarahumara ethnic group is composed of indigenous people from the Sierra Madre Occidental of Mexico. Conditions of isolation and poverty compel them to migrate to the city in search of better opportunities. This work aims to explore the influence of migration on the growth and nutritional status of Tarahumara schoolchildren. METHODS: One hundred Tarahumara students were analyzed (50 rural with a mean age of 9.78 +/- 1.25 years; 50 urban aged 10.0 +/- 1.04 years), comparing anthropometric indicators and body composition (T-Student, U Mann-Whitney Tests). RESULTS: Twenty percent of rural girls and 35% of rural boys showed stunted growth compared to only 9% of the urban girls (no stunted growth among urban boys). Migrants showed greater body size, skinfold thickness, and fat percentage. Weight excess, understood as an increase in the prevalence of overweight and obesity, was detected in 17.8% of urban boys and 13.6% of urban girls compared to 10.0% of boys and 3.3% of girls of the rural series. CONCLUSION: Migration reduces stunting and increases adiposity. PMID- 27717076 TI - Liquid-Phase Separation Methods for Environmental Analysis.

AB - BACKGROUND: Vitamin D is suggested to reduce cardiovascular risk. HYPOTHESIS: Circulating levels of plasma lipids and other cardiovascular risk factors may differ between statin-treated patients with different vitamin D status. METHODS: We studied 3 age- and weight-matched groups of men with elevated low-density lipoprotein cholesterol (LDL-C) levels: vitamin D-naive men with vitamin D insufficiency (group A, n = 18), men with vitamin D deficiency/insufficiency effectively treated with vitamin D preparations (group B, n = 16), and vitamin D naive men with normal vitamin D status (group C, n = 16). All patients were then treated with atorvastatin (20 mg daily) for 4 months. Plasma lipids, glucose homeostasis markers, and plasma levels of uric acid, high-sensitivity C-reactive protein (hsCRP), homocysteine, and fibrinogen were assessed before and at the end of atorvastatin therapy. RESULTS: Study groups did not differ in baseline levels of plasma lipids. Men with vitamin D deficiency or insufficiency effectively treated with vitamin D preparations were characterized by decreased insulin sensitivity and higher circulating levels of hsCRP, homocysteine, and fibrinogen in comparison with the remaining groups of patients. Although atorvastatin decreased plasma levels of total cholesterol and LDL-C to a similar extent in all study groups, its effect on uric acid, hsCRP, homocysteine, and fibrinogen was more pronounced in patients from groups B and C than in men from group A. Moreover, in patients with vitamin D insufficiency, atorvastatin impaired insulin sensitivity. CONCLUSIONS: The obtained results indicate that the strength of pleiotropic effects of atorvastatin depends on vitamin D status. PMID- 27717078 TI - Acute effects of resistance exercise on affect, arousal, and urge to drink in temporarily abstinent young adult hazardous drinkers. AB - BACKGROUND AND OBJECTIVE: Young adults frequently engage in hazardous alcohol consumption, and many meet the diagnostic criteria for an alcohol use disorder. The urge to drink is a defining symptom of alcohol dependence, and it is closely tied to and exacerbated by negative affect. This study examined the acute effect of resistance exercise on affect, arousal, and drinking urges in young adult (ages 21-40) hazardous drinkers. METHODS: On two separate occasions, 14 participants underwent an 18-hour alcohol abstinence before completing, in a counter-balanced manner, a 20-minute session of resistance exercise and a 20 minute video control. RESULTS: Significant improvements in affect (t = 2.07, p = .04) and arousal (t = 4.09, p < .01), but not urge to drink, were found with exercise. CONCLUSION: Single sessions of resistance exercise can positively alter affect and arousal during alcohol abstinence. SCIENTIFIC SIGNIFICANCE: Practical exercise interventions designed to alter affect and arousal could potentially alter drinking. (Am J Addict 2016;25:623-627).

AB - A unique metal-free aerobic oxidation of primary amines via visible light photocatalytic double carbon-carbon bonds cleavage and multi carbon-hydrogen bonds oxidation was observed. Aerobic oxidation of primary amines could be controlled to afford acids by using dioxane with 18 W CFL, and lactones by using DMF with 8 W green LEDs, respectively. A plausible mechanism was proposed based on control experiments. This observation showed direct evidences for the fragmentation in the aerobic oxidation of aliphatic primary amines. PMID- 27717080 TI - An illustrated comparison of processing methods for phase MRI and QSM: removal of background field contributions from sources outside the region of interest. AB - The elimination of so-called background fields is an essential step in phase MRI and quantitative susceptibility mapping (QSM). Background fields, which are caused by sources outside the region of interest (ROI), are often one to two orders of magnitude stronger than tissue-related field variations from within the ROI, hampering quantitative interpretation of field maps. This paper reviews the current literature on background elimination algorithms for QSM and provides insights into similarities and differences between the many algorithms proposed. We discuss the basic theoretical foundations and derive fundamental limitations of background field elimination. Copyright (c) 2016 John Wiley & Sons, Ltd.

PMID- 27717082 TI - Stratification of unresponsive patients by an independently validated index of brain complexity. AB - OBJECTIVE: Validating objective, brain-based indices of consciousness in behaviorally unresponsive patients represents a challenge due to the impossibility of obtaining independent evidence through subjective reports. Here we address this problem by first validating a promising metric of consciousness the Perturbational Complexity Index (PCI)-in a benchmark population who could confirm the presence or absence of consciousness through subjective reports, and then applying the same index to patients with disorders of consciousness (DOCs). METHODS: The benchmark population encompassed 150 healthy controls and communicative brain-injured subjects in various states of conscious wakefulness, disconnected consciousness, and unconsciousness. Receiver operating characteristic curve analysis was performed to define an optimal cutoff for discriminating between the conscious and unconscious conditions. This cutoff was then applied to a cohort of noncommunicative DOC patients (38 in a minimally conscious state [MCS] and 43 in a vegetative state [VS]). RESULTS: We found an empirical cutoff that discriminated with 100% sensitivity and specificity between the conscious and the unconscious conditions in the benchmark population. This cutoff resulted in a sensitivity of 94.7% in detecting MCS and allowed the identification of a number of unresponsive VS patients (9 of 43) with high values of PCI, overlapping with the distribution of the benchmark conscious condition. INTERPRETATION: Given its high sensitivity and specificity in the benchmark and MCS population, PCI offers a reliable, independently validated stratification of unresponsive patients that has important physiopathological and therapeutic implications. In particular, the high-PCI subgroup of VS patients may retain a capacity for consciousness that is not expressed in behavior. Ann Neurol 2016;80:718-729. PMID- 27717083 TI - T-cell acute lymphoblastic leukemia in infants has distinct genetic and epigenetic features compared to childhood cases. AB - For reasons not yet understood, nearly all infants with acute lymphoblastic leukemia (ALL) are diagnosed with the B-cell type, with T-ALL in infancy representing a very rare exception. Clinical and molecular knowledge about infant T-ALL is still nearly completely lacking and it is also still unclear whether it represents a distinct disease compared to childhood T-ALL. To address this, we performed exome sequencing of three infant cases, which enabled the detection of mutations in NOTCH2, NOTCH3, PTEN, and KRAS. When analyzing the transcriptomes and miRNomes of the three infant and an additional six childhood T-ALL samples, we found 760 differentially expressed mRNAs and 58 differentially expressed miRNAs between these two cohorts. Correlation analysis for differentially expressed miRNA-mRNA target pairs revealed 47 miRNA-mRNA pairs, with many of them previously described to be aberrantly expressed in leukemia and cancer. Pathway analysis revealed differentially expressed pathways and upstream regulators related to the immune system or cancerogenesis such as the ERK5 pathway, which was activated in infant T-ALL. In summary, there are distinct molecular features in infant compared to childhood T-ALL on a transcriptomic and epigenetic level, which potentially have an impact on the development and course of the disease.

PMID- 27717085 TI - Copper-Coated Liquid-Crystalline Elastomer via Bioinspired Polydopamine Adhesion and Electroless Deposition. AB - This study explores the functionalization of main-chain nematic elastomers with a conductive metallic surface layer using a polydopamine binder. Using a two-stage thiol-acrylate reaction, a programmed monodomain is achieved for thermoreversible actuation. A copper layer (~155 nm) is deposited onto polymer samples using electroless deposition while the samples are in their elongated nematic state. Samples undergo 42% contraction when heated above the isotropic transition temperature. During the thermal cycle, buckling of the copper layer is seen in the direction perpendicular to contraction; however, transverse cracking occurs due to the large Poisson effect experienced during actuation. As a result, the electrical conductivity of the layer reduced quickly as a function of thermal cycling. However, samples do not show signs of delamination after 25 thermal cycles. These results demonstrate the ability to explore multifunctional liquid crystalline composites using relatively facile synthesis, adhesion, and deposition techniques.

AB - Direct conversion of methane to chemical feedstocks such as methanol under mild conditions is a challenging but ideal solution for utilization of methane. Pd1 O4 single-sites anchored on the internal surface of micropores of a microporous silicate exhibit high selectivity and activity in transforming CH4 to CH3 OH at 50-95 degrees C in aqueous phase through partial oxidation of CH4 with H2 O2 . The selectivity for methanol production remains at 86.4 %, while the activity for methanol production at 95 degrees C is about 2.78 molecules per Pd1 O4 site per second when 2.0 wt % CuO is used as a co-catalyst with the Pd1 O4 @ZSM-5. Thermodynamic calculations suggest that the reaction toward methanol production is highly favorable compared to formation of a byproduct, methyl peroxide. PMID- 27717087 TI - Depressive symptoms in patients with wounds: A cross-sectional study. AB - Depression slows wound healing in patients with chronic wounds. The prevalence of depressive symptoms differs in the literature and the current understandings of factors related to depression in patients with wounds have been limited. To investigate the prevalence of depressive symptoms and the associated factors in patients with wounds, we performed this retrospective study in which depressive symptoms were evaluated with the Patient Health Questionnaire 9-item (PHQ-9). Valid PHQ-9 scores were collected from 222 patients (112 males and 110 females; age: 64.1 +/- 15.8) out of 260 consecutive patients evaluated at an outpatient physical therapy wound clinic during 2012-2015. The proportion of patients with minimal to severe depressive symptoms was 81.5% [80.8% in patients with venous leg ulcers (VLUs) and 82.0% in non-VLUs]; 22.1% patients with wounds had scored positive for depression (moderate to severe depressive symptoms). Specific proportions of positive depression screening were 26.6% in patients with VLUs and 18.8% in non-VLU patients, and 14.1 and 40.0% in patients with wounds <90 and >= 90 days as of initial examination, respectively. PHQ-9 scores were significantly decreased from 5.85 +/- 6.01 at initial examination to 3.42 +/- 4.35 at last visit (p < 0.001). The odds of a positive depression screening was 3.20 (95% CI = [1.49, 6.87]) in patients with wounds >= 90 days (vs. < 90 days) and 2.53 (95% CI = [1.26, 5.08]) in patients with pain related to the wounds (vs. without pain), after patients' age, gender, and race were controlled for. No difference was found in proportions of positive depression screening between VLUs and other wound diagnoses. Depressive symptoms were common in patients with wounds, especially in patients with wounds >=90 days and with pain related to the wounds at initial examination. Therefore, clinicians should take into consideration patients' mental status upon management of wounds. PMID- 27717089 TI - Chromosomal microarray in a highly consanguineous population: diagnostic yield, utility of regions of homozygosity, and novel mutations. AB - Chromosomal microarray (CMA) has significantly improved diagnosing copy number variations (CNVs). Single nucleotide polymorphism (SNP) arrays confer additional utility in detecting regions of homozygosity (ROH). Investigating ROH for genes associated with recessive disorders for follow-up sequencing can aid in diagnosis. In this study, we performed a retrospective review of clinical and molecular data for 227 individuals from a highly consanguineous population who previously had a CMA. Pathogenic CNVs were identified in 32 (14%) cases; ROH suggesting uniparental disomy (UPD) in three (1%) cases, and an additional 25 (11%) individuals were diagnosed with recessive disorders caused by mutations in ROH candidate genes, thereby increasing the CMA diagnostic yield to 26%. Among the 25 individuals with recessive diseases, 18 had novel mutations in 16 genes (ASPM, SPINK5, QARS, MEGF10, SPATA7, GMPPA, ABCA4, SRD5A2, RPGRIP1L, MET, SLC12A6, ALDH1A3, TNFRSF11A, FLNB, PHGDH, and FKBP10) including five with phenotypic expansion. PMID- 27717088 TI - Intralaminar and tectal projections to the subthalamus in the rat. AB - Projections from the posterior intralaminar thalamic nuclei and the superior colliculus (SC) to the subthalamic nucleus (STN) and the zona incerta (ZI) have been described in the primate and rodent. The aims of this study was to investigate several questions on these projections, using modern neurotracing techniques in rats, to advance our understanding of the role of STN and ZI. We examined whether projection patterns to the subthlamus can be used to identify homologues of the primate centromedian (CM) and the parafascicular nucleus (Pf) in the rodent, the topography of the projection including what percent of intralaminar neurons participate in the projections, and electron microscopic examination of intralaminar synaptic boutons in STN. The aim on the SC subthalamic projection was to examine whether STN is the main target of the projection. This study revealed: (i) the areas similar to primate CM and Pf could be recognized in the rat; (ii) the Pf-like area sends a very heavy topographically organized projection to STN but very sparse projection to ZI, which suggested that Pf might control basal ganglia function through STN; (iii) the projection from the CM-like area to the subthalamus was very sparse; (iv) Pf boutons and randomly sampled asymmetrical synapses had similar distributions on the dendrites of STN neurons; and (v) the lateral part of the deep layers of SC sends a very heavy projection to ZI and moderate to sparse projection to limited parts of STN, suggesting that SC is involved in a limited control of basal ganglia function. PMID- 27717090 TI - How the truffle got its mate: insights from genetic structure in spontaneous and planted Mediterranean populations of Tuber melanosporum. AB - The life cycles and dispersal of edible fungi are still poorly known, thus limiting our understanding of their evolution and domestication. The prized Tuber melanosporum produces fruitbodies (fleshy organs where meiospores mature) gathered in natural, spontaneously inoculated forests or harvested in plantations of nursery-inoculated trees. Yet, how fruitbodies are formed remains unclear, thus limiting yields, and how current domestication attempts affect population genetic structure is overlooked. Fruitbodies result from mating between two haploid individuals: the maternal parent forms the flesh and the meiospores, while the paternal parent only contributes to the meiospores. We analyzed the genetic diversity of T. melanosporum comparatively in spontaneous forests vs. plantations, using SSR polymorphism of 950 samples from South-East France. All populations displayed strong genetic isolation by distance at the metric scale, possibly due to animal dispersal, meiospore persistence in soil, and/or exclusion of unrelated individuals by vegetative incompatibility. High inbreeding was consistently found, suggesting that parents often develop from meiospores produced by the same fruitbody. Unlike maternal genotypes, paternal mycelia contributed to few fruitbodies each, did not persist over years, and were undetectable on tree mycorrhizae. Thus, we postulate that germlings from the soil spore bank act as paternal partners. Paternal genetic diversity and outbreeding were higher in plantations than in spontaneous truffle-grounds, perhaps because truffle growers disperse fruitbodies to maintain inoculation in plantations. However, planted and spontaneous populations were not genetically isolated, so that T. melanosporum illustrates an early step of domestication where genetic structure remains little affected.

AB - To date, there is a major effort in deciphering the role of complex microbial communities, especially the oral and gut microbiomes, in the pathogenesis of various diseases. Increasing evidence indicates a key role for the oral microbiome in autoimmune diseases. In this review article, we discuss links of the oral microbiota to a group of autoimmune diseases, that is, Sjogren's syndrome (SS), systemic lupus erythematosus (SLE), Crohn's disease (CD), and rheumatoid arthritis (RA). We particularly focus on factors that affect the balance between the immune system and the composition of microbiota leading to dysbiosis, loss of tolerance and subsequent autoimmune disease progression and maintenance. PMID- 27717094 TI - Terminal differentiation of cortical neurons rapidly remodels RanGAP-mediated nuclear transport system. AB - Terminal differentiation of neurons is accompanied by irreversible exit from the cell cycle and expression of neuronal phenotypes. The molecular mechanism whereby committed neuronal progenitors lose their ability to reenter the cell cycle is largely unknown. Here, we report that the nuclear transport system is rapidly remodeled in primary cortical progenitor cells (CPCs) at the very beginning of neuronal terminal differentiation. High levels of Ran GTPase-activating protein 1 (RanGAP), a key regulator of the Ran GTP-GDP cycle, in primary CPCs are drastically reduced upon neuronal induction. Small ubiquitin-like modifier (SUMO) 2/3-conjugated RanGAP undergoes desumoylation and degradation in neuronally committed CPCs, where reduced RanGAP levels impede the nuclear import of nucleocytoplasmic shuttling proteins including the DNA replication initiation factor Cdc6. Furthermore, RNAi-mediated down-regulation of RanGAP expression in undifferentiated CPCs induces neuronal phenotypes including cell cycle exit. Our data suggest that remodeling of the RanGAP-mediated nuclear transport system plays a key role in cell cycle exit for terminal differentiation of cortical neurons.

PMID- 27717093 TI - Spatial variability and reproducibility of GABA-edited MEGA-LASER 3D-MRSI in the brain at 3 T. AB - The reproducibility of gamma-aminobutyric acid (GABA) quantification results, obtained with MRSI, was determined on a 3 T MR scanner in healthy adults. In this study, a spiral-encoded, GABA-edited, MEGA-LASER MRSI sequence with real-time motion-scanner-instability corrections was applied for robust 3D mapping of neurotransmitters in the brain. In particular, the GABA+ (i.e. GABA plus macromolecule contamination) and Glx (i.e. glutamate plus glutamine contamination) signal was measured. This sequence enables 3D-MRSI with about 3 cm3 nominal resolution in about 20 min. Since reliable quantification of GABA is challenging, the spatial distribution of the inter-subject and intra-subject variability of GABA+ and Glx levels was studied via test-retest assessment in 14 healthy volunteers (seven men-seven women). For both inter-subject and intra subject repeated measurement sessions a low coefficient of variation (CV) and a high intraclass correlation coefficient (ICC) were found for GABA+ and Glx ratios across all evaluated voxels (intra-/inter-subject: GABA+ ratios, CV ~ 8%-ICC > 0.75; Glx ratios, CV ~ 6%-ICC > 0.70). The same was found in selected brain regions for Glx ratios versus GABA+ ratios (CV varied from about 5% versus about 8% in occipital and parietal regions, to about 8% versus about 10% in the frontal area, thalamus, and basal ganglia). These results provide evidence that 3D mapping of GABA+ and Glx using the described methodology provides high reproducibility for application in clinical and neuroscientific studies. PMID- 27717096 TI - Prevalence of Helicobacter pylori infection in newly arrived refugees attending the Migrant Health Service, South Australia. AB - BACKGROUND: To determine the prevalence of Helicobacter pylori infection in the refugee population attending the Migrant Health Service, South Australia, identify demographic factors associated with infection and compare prevalence of infection in refugees with that of the nonrefugee population in Australia. MATERIALS AND METHODS: Cross-sectional study conducted between October 2010 and August 2013. Monoclonal stool antigen testing for H. pylori infection is performed as part of a comprehensive health assessment for newly arrived refugees. The sample population included 922 adults and children. Outcome measures were (i) prevalence of H. pylori infection (ii) association between demographic factors such as sex, ethnicity and age, and H. pylori infection. RESULTS: H. pylori infection was detected in 198 (21.5%) participants (95% CI 18.9%-24.3%). The odds of infection were lower in females OR 0.71 (95% CI 0.51 0.98) compared to males. Compared to Middle Eastern participants, the odds of infection were 1.75 (95% CI 1.17-2.62) times higher in African and 1.90 (95% CI 1.10-3.26) times higher in Burmese participants. Infection was not associated with age. DISCUSSION AND CONCLUSION: H. pylori infection is common among newly arrived refugees. The long latency of infection to development of complications and the availability of testing and relatively effective eradication regimens all add weight to a decision to screen in this population. PMID- 27717097 TI - p16 immunostaining in keratinocytic neoplasia in organ transplant recipients: Bowen's disease shows a characteristic pattern. AB - BACKGROUND: For selecting therapy, it is important to distinguish different types of keratinocytic neoplasia. It is sometimes difficult to make histopathologic diagnosis, especially in organ transplant recipients (OTR) who develop numerous lesions. METHODS: To investigate p16 immunostaining in different types of keratinocytic neoplasia in OTR, we studied 59 actinic keratoses (AK), 51 Bowen' s disease (BD), 63 squamous cell carcinomas (SCC), 16 benign keratotic lesions (BKL) from 31 OTR patients and 25 controls (eczema and psoriasis). Tissue sections were stained for H&E and p16. We scored intensity, proportion and distribution of p16 positive lesional cells. RESULTS: In 19% of AK, 92% of BD, 35% of SCC and 12% of BKL more than 15% of lesional cells were p16-positive. In 16% of AK, 80% of BD, 18% of SCC and 13% of BKL strong p16 staining was observed. BKL, AK and SCC showed focal and patchy staining, BD showed diffuse pattern with strong staining of all atypical cells. Sparing of the basal layer was predominantly seen in BD. No control specimen showed p16-overexpression. CONCLUSIONS: p16 immunostaining shows a characteristic pattern in BD, but not in AK, SCC and BKL. It appears useful in recognizing BD, but not in differentiating between other keratinocytic neoplasia. PMID- 27717098 TI - Neuropeptides shaping the central nervous system development: Spatiotemporal actions of VIP and PACAP through complementary signaling pathways. AB - Pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal peptide (VIP) are neuropeptides with wide, complementary, and overlapping distributions in the central and peripheral nervous systems, where they exert important regulatory roles in many physiological processes. VIP and PACAP display a large range of biological cellular targets and functions in the adult nervous system including regulation of neurotransmission and neuroendocrine secretion and neuroprotective and neuroimmune responses. As the main focus of the present review, VIP and PACAP also have been long implicated in nervous system development and maturation through their interaction with the seven transmembrane domain G protein-coupled receptors, PAC1, VPAC1, and VPAC2, initiating multiple signaling pathways. Compared with PAC1, which solely binds PACAP with very high affinity, VPACs exhibit high affinities for both VIP and PACAP but differ from each other because of their pharmacological profile for both natural accessory peptides and synthetic or chimeric molecules, with agonistic and antagonistic properties. Complementary to initial pharmacological studies, transgenic animals lacking these neuropeptides or their receptors have been used to further characterize the neuroanatomical, electrophysiological, and behavioral roles of PACAP and VIP in the developing central nervous system. In this review, we recapitulate the critical steps and processes guiding/driving neurodevelopment in vertebrates and superimposing the potential contribution of PACAP and VIP receptors on the given timeline. We also describe how alterations in VIP/PACAP signaling may contribute to both (neuro)developmental and adult pathologies and suggest that tuning of VIP/PACAP signaling in a spatiotemporal manner may represent a novel avenue for preventive therapies of neurological and psychiatric disorders.

AB - The time dependence of the diffusion coefficient is a hallmark of tissue complexity at the micrometer level. Here we demonstrate how biophysical modeling, combined with a specifically tailored diffusion MRI acquisition performing diffusion tensor imaging (DTI) for varying diffusion times, can be used to determine fiber size and membrane permeability of muscle fibers in vivo. We describe the random permeable barrier model (RPBM) and its assumptions, as well as the details of stimulated echo DTI acquisition, signal processing steps, and potential pitfalls. We illustrate the RPBM method on a few pilot examples involving human subjects (previously published as well as new), such as revealing myofiber size derived from RPBM increase after training in a calf muscle, and size decrease with atrophy in shoulder rotator cuff muscle. Finally, we comment on the potential clinical relevance of our results. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - OBJECTIVES: Children younger than 12 months of age are eligible for childhood vaccines through the public health system in Guinea-Bissau. To limit open vial wastage, a restrictive vial opening policy has been implemented; 10-dose measles vaccine vials are only opened if six or more children aged 9-11 months are present at the vaccination post. Consequently, mothers who bring their child for measles vaccination can be told to return another day. We aimed to describe the household experience and estimate household costs of seeking measles vaccination in rural Guinea-Bissau. METHODS: Within a national sample of village clusters under demographic surveillance, we interviewed mothers of children aged 9-21 months about their experience with seeking measles vaccination. From information about time and money spent, we calculated household costs of seeking measles vaccination. RESULTS: We interviewed mothers of 1308 children of whom 1043 (80%) had sought measles vaccination at least once. Measles vaccination coverage was 70% (910/1308). Coverage decreased with increasing distance to the health centre. On average, mothers who had taken their child for vaccination took their child 1.4 times. Mean costs of achieving 70% coverage were 2.04 USD (SD 3.86) per child taken for vaccination. Half of the mothers spent more than 2 h seeking vaccination and 11% spent money on transportation. CONCLUSIONS: We found several indications of missed opportunities for measles vaccination resulting in suboptimal coverage. The household costs comprised 3.3% of the average monthly income and should be taken into account when assessing the costs of delivering vaccinations.

AB - The migratory locust (Locusta migratoria) shows aggregative traits in nymph marching bands and swarm formations through mutual olfactory attraction of conspecifics. However, olfactory preference in different nymph stages in gregarious locusts is not sufficiently explored. In this study, we found that the nymph olfactory preference for gregarious volatiles exhibited obvious variations at different developmental stages. The gregarious locusts show attractive response to conspecific volatiles from the third stadium. Transcriptome comparison between third- and fourth-stadium nymphs showed that the G protein coupled receptor (GPCR) pathways are significantly enriched. Amongst the genes present in GPCR pathways, the expression level of calmodulin in locust brains significantly increased from the third- to the fourth-stadium nymphs. Amongst the four octopamine receptors (OARs) belonging to the GPCR family, only OAR alpha1 showed similar expression patterns to those of calmodulin, and knockdown of OAR alpha1 reduced the expression level of calmodulin. RNA interference of calmodulin decreased locomotion and induced the loss of olfactory attraction in gregarious locusts. Moreover, the activation of OAR alpha1 in calmodulin-knockdown locusts did not induce olfactory attraction of the nymphs to gregarious volatiles. Thus, calmodulin as a downstream gene of octopamine-OAR alpha1 (OA-OAR alpha1) signalling mediates olfactory attraction in gregarious locusts. Overall, this study provides novel insights into the mechanism of OA-OAR alpha1 signalling involved in olfactory attraction of gregarious locusts. PMID- 27717102 TI - Heteroatomic Conjugated Polymers and the Spectral Tuning of Electroluminescence via a Supramolecular Coordination Strategy. AB - The unique electronic structures of heteroatomic conjugated polymers (HCPs) offer an attractive platform to tune optoelectronic properties via a supramolecular coordination strategy. This study reports on an sp2 nitrogen heteroatom containing fluorene-based copolymer namely poly(9,9-dioctylfluorene-co-9,9 dioctyldiazafluoren-2,7-yl) (PF8-co-DAF8), with ~20% DAF8 units. Tuning the optoelectronic properties of PF8-co-DAF8 via supramolecular coordination with a Lewis acid (B(C6 F5 )3 or AlCl3 ) is explored. Formation of either the PF8-co DAF8-B(C6 F5 )3 or PF8-co-DAF8-AlCl3 adducts reduces the optical gap and causes an attendant redshift of the photoluminescence spectra. Controlling the degree and strength of the coordination allows the emission color to be tuned from blue through to green and yellow. This strategy is successfully implemented for polymer light-emitting diodes, confirming the large degree of spectral tuning whilst maintaining good device performance. Maximum luminous efficiencies, eta ~ 1.55 cd A-1 @ 2120 cd m-2 , 1.32 cd A-1 @ 1424 cd m-2 , and 2.56 cd A-1 @ 910 cd m-2 are, respectively, recorded for the blue-emitting diodes with Commission Internationale de L'Eclairage (CIE) (x, y) coordinates = (0.16, 0.16), the white emitting diodes with CIE (x, y) = (0.28, 0.38) and the green-emitting diodes with CIE (x, y) = (0.33, 0.52). The results highlight the versatility of the supramolecular coordination strategy in modifying the electronic structure of HCPs.

AB - Glutathione S-transferases (GSTs) are dimeric proteins that play a key role in phase II cellular detoxification. Here, the first crystal structure of a GST class-mu from marine crustacean shrimp Litopenaeus vannamei is reported at a resolution of 2.0 A. The coordinates reported here have the lowest sequence identity with previously reported GSTs class-mu deposited at the Protein Data Bank (PDB), although they have subtle conformational differences. One key feature of GST class-mu from L. vannamei is the active site crevice markedly reduced when it is compared with other GSTs class-mu. This finding together with the chemical change of residues into the cavity (F112 and Y210) points to a particular specialization in which smallest xenobiotics with nonstandard chemical characteristics can be bound to the H-site. This suggests that marine organisms have evolved structural strategies to provide efficient selectivity toward xenobiotics to be disposed of by the phase II detoxification process.

PMID- 27717105 TI - Acute myeloid leukemia in the elderly (age 70 yr or older): long-term survivors. AB - OBJECTIVE: Little data exist regarding long-term survival in elderly patients with acute myeloid leukemia (AML). METHODS: In view of the fact that most deaths occurred during the first 3 yr, this study examined long-term survival in this patient population, defined as overall survival for at least 3 yr with the aim to determine the number of long-term survivors and to identify factors that might impact on longer survival. RESULTS: The criterion for entry into this cohort was fulfilled by 57 patients among 302 seen over a 14-yr period (19%): 12 patients who never achieved complete remission (CR), 21 patients who relapsed after CR achievement, and 24 patients who achieved CR and did not relapse, including three patients who died while in CR and 21 patients still alive in first CR at the time of analysis. The pretreatment prognostic importance of cytogenetics was still apparent. However, some patients with secondary AML and/or unfavorable-risk markers belonged to long survivors. The cohort involved mainly patients treated by intensive chemotherapy, but also some patients receiving low-intensity therapies. CONCLUSION: Improved results should come from a better selection of patients to a more 'personalized' therapeutic approach combined with better supportive care assessment. PMID- 27717106 TI - Differential effects of oxytocin on mouse hippocampal oscillations in vitro. AB - The hypothalamic neuropeptide oxytocin (OT) controls childbirth and lactation, is involved in social behaviors, plays a role in various psychiatric disorders, and has effects on learning and memory. Although behavioral effects of OT have been extensively studied, much less is known about its effects on neuronal and network activity patterns. Here, we investigate the effect of OT on two major patterns of hippocampal network activity in mouse hippocampal slices. We studied different in vitro models of gamma-frequency oscillations and sharp wave-ripple complexes (SPW R), two patterns implicated in spatial memory formation and memory consolidation respectively. Strikingly, we found a profound difference of OT on these distinct, mutually exclusive activity patterns. While gamma oscillations where not affected by the activation of hippocampal OT receptors, SPW-R were potently and rapidly suppressed. Interestingly, the temporal precision of oscillation-coupled spikes was enhanced at the same time. Thus, OT exerts strongly different modulatory effects on different network patterns, most likely by inhibition of different sets of inhibitory interneurons. The observed dichotomy between gamma and SPW-R oscillations may have profound effects on the behavioral and cognitive effects of OT which are relevant to cognitive processes and to psychiatric diseases. PMID- 27717107 TI - Management of patients with ocular manifestations in vesiculobullous disorders affecting the mouth. AB - Pemphigoid and pemphigus diseases as well as Stevens-Johnson syndrome present as vesiculobullous disorders of the skin and may additionally involve both the oral cavity and the ocular surface. Ocular involvement ranges from mild irritation and dry eye disease to chronic conjunctivitis, symblepharon, eyelid malposition, ocular surface scarring and severe visual loss. In addition to diagnostic assessments, ophthalmologists must treat the dry eye and meibomian gland dysfunction components of these diseases using a stepladder approach, including eyelid hygiene and lubricants. Topical anti-inflammatory therapy is used to treat acute inflammatory exacerbations of the ocular surface, but it cannot prevent scarring alone. Intralesional antimetabolite therapy can cause regression of conjunctival pathology in selected cases. Hence, patients with vesiculobullous disorders should be managed by a multidisciplinary team representing ophthalmology, dermatology, otolaryngology, oral medicine and pathology, internal medicine and intensive care. Systemic treatments including corticosteroids, azathioprine, cyclophosphamide, cyclosporine and mycophenolate mofetil help control inflammation. Intravenous immunoglobulins, plasmapheresis and targeted antibody therapy can be used in selected, severe and treatment-resistant cases. Local surgical management may include debridement of pseudomembranes, lysis of symblepharon, amniotic and mucous membrane grafting as well as reconstructive procedures. Prospective, multicentre, international studies are recommended to further support evidence-based practice. PMID- 27717109 TI - Follicular development and morphological changes in the vaginal epithelium during the estrous cycle of Galea spixii. AB - The current study aimed to determine if characteristics observed in vaginal cytology during the estrous cycle of female SYT cavies corresponded with proliferation of the vaginal epithelium, characterized by proliferating cell nuclear antigen (PCNA) immunolocalization, and with follicular development at different phases of the estrous cycle. After determining estrous cycle phases by vaginal cytology, females were euthanized at metestrus, diestrus, proestrus, and estrus. Histological study of the vaginal epithelium and ovary were then performed. Immunohistochemistry for PCNA in vaginal tissue at each cycle phase was also performed. Superficial cornified cells and early post-ovulatory follicles were found at estrus. Few nuclei below the enucleate superficial cells were immunoreactive to PCNA. At metestrus, the vaginal epithelium underwent desquamation and lost the superficial cornified cells; basal and intermediate cells appeared, and the post-ovulatory follicle formed an early corpus luteum. No PCNA immunoreactivity was observed. At diestrus, the corpus luteum was developed, and the vaginal epithelium contained basal and intermediate cells. There was PCNA immunoreactivity in the cellular nucleus in the germinative stratum of the epithelium. Because of the growth and maturation of ovarian follicles, the vaginal epithelium suffered intense proliferation at proestrus. Vaginal cytology revealed large intermediate cells and nucleated and enucleated superficial cornified cells. In the ovary, mature follicles were present. More apparent immunoreactivity of PCNA in the germinative layer was found. In summary, we inferred that vaginal exfoliative findings matched the proliferation process of the vaginal epithelium. PCNA immunolocalization occurred as well as corresponding follicular development in the ovaries. PMID- 27717108 TI - Blockade of high mobility group box 1 augments antitumor T-cell response induced by peptide vaccination as a co-adjuvant. AB - High mobility group box 1 (HMGB1) is a member of the family of damage-associated molecular patterns, which cause inflammation and trigger innate immunity through Toll-like receptors 2/4 and the receptor for advanced glycation end products. We examined the effect of glycyrrhizin, a selective inhibitor of HMGB1, on the induction of CTLs in mice. B6 mice, either OT-1 spleen cell-transferred or untransferred, were immunized with an s.c. injection of OVA257-264 peptide with topical imiquimod, and glycyrrhizin was mixed with the antigen peptide. Proliferation of OT-1 cells after immunization was enhanced by glycyrrhizin. The effect of glycyrrhizin was confirmed in other adjuvant systems, such as CpG oligonucleotide and monophosphoryl lipid A, but glycyrrhizin was not effective in Freund's incomplete adjuvant system. The augmenting effects of glycyrrhizin were also observed in other synthetic HMGB1 inhibitors, gabexate mesilate, nafamostat, and sivelestat. Thus, the effects are common to the HMGB1 inhibitors. Induction of CTLs detected by gamma-interferon enzyme-linked immunospot assay was similarly augmented by glycyrrhizin. In a therapeutic vaccine model, glycyrrhizin inhibited the growth of s.c. transplanted EG.7 tumors. Expression of inflammatory cytokines in the skin inoculation site was downregulated by glycyrrhizin. These results suggest that HMGB1 inhibitors might be useful as a co-adjuvant for peptide vaccination with an innate immunity receptor-related adjuvant.

AB - The first quaternary ammonium-group-containing [FeFe]-hydrogenase models [(MU PDT)Fe2 (CO)4 {kappa2 -(Ph2 P)2 N(CH2 )2 NMe2 BzBr}] (2; PDT=propanedithiolate) and [(MU-PDT)Fe2 (CO)4 {MU-(Ph2 P)2 N(CH2 )2 NMe2 BzBr}] (4) have been prepared by the quaternization of their precursors [(MU-PDT)Fe2 (CO)4 {kappa2 -(Ph2 P)2 N(CH2 )2 NMe2 }] (1) and [(MU-PDT)Fe2 (CO)4 {MU-(Ph2 P)2 N(CH2 )2 NMe2 }] (3) with benzyl bromide in high yields. Although new complexes 1-4 have been fully characterized by spectroscopic and X-ray crystallographic studies, the chelated complexes 1 and 2 converted into their bridged isomers 3 and 4 at higher temperatures, thus demonstrating that these bridged isomers are thermodynamically favorable. An electrochemical study on hydrophilic models 2 and 4 in MeCN and MeCN/H2 O as solvents indicates that the reduction potentials are shifted to less negative potentials as the water content increases. This outcome implies that both 2 and 4 are more easily reduced in the mixed MeCN/H2 O solvent than in MeCN. In addition, hydrophilic models 2 and 4 act as electrocatalysts and achieve higher icat /ip values and turnover numbers (TONs) in MeCN/H2 O as a solvent than in MeCN for the production of hydrogen from the weak acid HOAc.

PMID- 27717112 TI - Activation of cannabinoid receptor 2 attenuates mechanical allodynia and neuroinflammatory responses in a chronic post-ischemic pain model of complex regional pain syndrome type I in rats. AB - Complex regional pain syndrome type 1 (CRPS-I) remains one of the most clinically challenging neuropathic pain syndromes and its mechanism has not been fully characterized. Cannabinoid receptor 2 (CB2) has emerged as a promising target for treating different neuropathic pain syndromes. In neuropathic pain models, activated microglia expressing CB2 receptors are seen in the spinal cord. Chemokine fractalkine receptor (CX3CR1) plays a substantial role in microglial activation and neuroinflammation. We hypothesized that a CB2 agonist could modulate neuroinflammation and neuropathic pain in an ischemia model of CRPS by regulating CB2 and CX3CR1 signaling. We used chronic post-ischemia pain (CPIP) as a model of CRPS-I. Rats in the CPIP group exhibited significant hyperemia and edema of the ischemic hindpaw and spontaneous pain behaviors (hindpaw shaking and licking). Intraperitoneal administration of MDA7 (a selective CB2 agonist) attenuated mechanical allodynia induced by CPIP. MDA7 treatment was found to interfere with early events in the CRPS-I neuroinflammatory response by suppressing peripheral edema, spinal microglial activation and expression of CX3CR1 and CB2 receptors on the microglia in the spinal cord. MDA7 also mitigated the loss of intraepidermal nerve fibers induced by CPIP. Neuroprotective effects of MDA7 were blocked by a CB2 antagonist, AM630. Our findings suggest that MDA7, a novel CB2 agonist, may offer an innovative therapeutic approach for treating neuropathic symptoms and neuroinflammatory responses induced by CRPS-I in the setting of ischemia and reperfusion injury. PMID- 27717113 TI - Incorporation and Remodeling of Bone Block Allografts in the Maxillary Reconstruction: A Randomized Clinical Trial. AB - BACKGROUND: Severe alveolar atrophy often presents a challenge for the implant surgery. The significant lack of bone in the alveolar ridges may compromise the final restorations both from the aesthetic and functional standpoints. OBJECTIVES: To evaluate the behavior of bone block allografts for the maxillary augmentation and to investigate its incorporation, remodeling, and implant survival rates in two different healing time points. MATERIAL AND METHODS: Sixty six consecutive patients (52 female/14 male, mean age: 57.95 +/- 9.06 years old), presenting 113 atrophic alveolar ridges underwent maxillary augmentation with fresh-frozen allogeneic bone blocks from tibia. Patients were randomly assigned in two groups: Group 1-patients who would wait 4 months for implant placement after grafting, and Group 2-patients who would wait 6 months. Events of infection, suture dehiscence or mucosal perforation were recorded. Cone-beam computed tomography scans were compared volumetrically between the time of the grafting surgery and reentry procedure after incorporation. Biopsies were collected and subjected to histological, histomorphometric and immunehistochemical analysis. RESULTS: A total of 305 implants were placed in the reconstructed sites. The mean resorption rate in Group 1 (13.98% +/- 5.59) was significantly lower than Group 2 (31.52% +/- 6.31). The amount of calcified tissue, newly formed bone and remaining graft particles demonstrated no difference between groups. The samples showed evident immunolabeling for the podoplanin protein in both groups. The implants cumulative survival rate was 94.76%. CONCLUSIONS: The findings of the present study indicate that there is a significant difference regarding the resorption of the grafts when waiting 4 or 6 months before placing the implants, even though no difference was found in the histological, histomorphometric, and immunohistochemical features. Both 4-month and 6-months healing times are suitable for the implant placement. PMID- 27717114 TI - A potential insect growth regulator for cockroach control: design, synthesis and bioactivity of N-terminal-modified allatostatin analogues. AB - BACKGROUND: The FGLa-allatostatins (ASTs) are a family of neuropeptides that can inhibit juvenile hormone biosynthesis by the corpora allata (CA) in vitro, and therefore they are regarded as insect growth regulator (IGR) candidates for pest control. In our previous studies, an AST mimic, H17, was found to have a significant effect on JH biosynthesis by cockroach CA, both in vitro and in vivo. To discover new potential mimics and explore the substituent effect on the inhibition of JH biosynthesis, 30 analogues, modified with various substituents on the benzene ring at the N-terminus of lead compound H17, were designed and synthesised. Their bioactivity in inhibiting JH biosynthesis by the CA of Diploptera punctata and the potency of M9, M10 and M11 in activation of Dippu AstR were evaluated. RESULTS: All the analogues showed an effect on JH biosynthesis by CA in vitro. M9, M10 and M11 can activate the Dippu-AstR, albeit with much lower potency than that of AST 1. M11 also exhibited improved in vitro activity (IC50 6.98 nm) in comparison with the lead compound H17 (IC50 29.5 nm). In particular, M11 displayed good in vivo activity in inhibiting JH biosynthesis and basal oocyte growth. CONCLUSION: The structure-activity relationship studies suggest that different positions of substituents on the benzene ring of the cinnamic acid can lead to different activities. The para-substitution on the benzene ring plays an important role in inhibiting JH biosynthesis in vitro. Moreover, M11 is considered to be a potential IGR for cockroach control.

AB - BACKGROUND: The effects of pomegranate juice (PJ) on the risk factors of non alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH) have been reported previously; however, the effects on NAFLD and its prevention have not yet been clarified. The present study aimed to evaluate the effects of PJ consumption with respect to the prevention of NAFLD/NASH development. Sprague Dawley rats were fed either a high-fat, high sugar diet (model group); a high fat, high sugar diet plus PJ (model+PJ); or a chow diet ad libitum for 7 weeks. Serum levels of fasting glucose, triglyceride, cholesterol, liver enzymes, insulin and hepatic tumor necrosis factor-alpha and tissue growth factor-beta gene expression were determined. Hepatic histology was examined by hemotoxylin and eosin staining. RESULTS: The model+PJ group had significantly lower hepatic steatosis, ballooning, lobular inflammation and portal inflammation (P < 0.001); lower hepatic pro-inflammatory and pro-fibrotic gene expression (P < 0.001); and lower plasma levels of alanine aminotransferase (P = 0.026), aspartate aminotransferase (P = 0.041), insulin (P < 0.001), triglycerides (P = 0.041) and glucose (P = 0.009) compared to the model group; however, weight gain, food intake and plasma high-density lipoprotein levels were not significantly different between these two groups. CONCLUSION: The data obtained in the present study indicate that the regular consumption of PJ can prevent NAFLD even in the presence of the other risk factors such as obesity, hypercholesterolemia, and high energy, fat and sugar intakes.

AB - AIM: Biliary atresia (BA) literature has focussed on the relationship between age at Kasai procedure (KP) and post-KP outcomes. This study primarily examines post KP outcomes including, 6-month normalisation of bilirubin, 5-year native liver survival (NLS), development of portal hypertension (PHT) and incidence of ascending cholangitis at a single tertiary paediatric centre in Australia. The study also evaluated prognostic factors which may influence these aforementioned outcomes. METHODS: Retrospective chart review of all BA cases between 1999 and 2014. Age at KP, liver biopsy results, use of ursodeoxycholic acid or prophylactic antibiotics and occurrence of PHT and ascending cholangitis post-KP were recorded and related to the primary post-KP outcome measures. RESULTS: BA was diagnosed in 29 patients. Twenty-four of 29 patients underwent KP. Median age at KP was 68 days (29-104). Fourteen of 24 (58.3%) had bridging fibrosis and 5 of 24 (20.8%) had cirrhosis at time of KP. Median follow-up was 8.4 years (2.08 15.58 years). Bilirubin normalisation within 6 months occurred in 7 of 24 (29.2%) patients and 5-year NLS was 45.8% (11/24). Fourteen of 24 (58.3%) had PHT and 18 of 24 (75%) patients had ascending cholangitis post-KP. Absence of bridging fibrosis in liver histology at KP was the only factor to be significantly associated with improved 5-year NLS. None of the other variables examined had a significant association with either 5-year NLS or bilirubin normalisation by 6 months. CONCLUSION: Five-year NLS in this series was 45.8%. Absence of bridging fibrosis at time of KP was the only factor significantly associated with improved 5-year NLS. PMID- 27717117 TI - Have we significantly underestimated the capacity in the Australian health system to treat chronic hepatitis C infection in an interferon-free era? AB - BACKGROUND: New antiviral therapies for hepatitis C infection may lead to an increase in capacity to treat because of their simplicity and safety. AIMS: To determine the likely current capacity of accredited treatment centres in treating hepatitis C (HCV) patients with interferon (IFN)-free direct acting antiviral (DAA) agents in Australia. METHOD: Data were collected from 22 centres before the introduction of DAA therapy - 11 sites from the Study 1 survey and an additional 11 sites from the Study 2 survey. The sites were selected based on consensus by viral hepatitis experts, in consultation with the NSW Agency for Clinical Innovation. The services were selected as they were experienced in the delivery of IFN-based treatments and/or had knowledge about IFN-free regimens. The sites selected offered a mix of metropolitan and regional clinics, opioid substitution clinics, Aboriginal services, general practitioner-initiated, criminal justice and nurse-led services. Following the survey, the first 3 months of actual treatment uptake, since listing in March and May 2016, became available for a comparison and were subsequently analysed. RESULTS: The survey indicated that an average of 27 h would be required to treat patients with IFN-based regimens. This was reduced to an average of 9 h if IFN-free regimens were used. The average number of patients on IFN-based treatment regimens per site was 87 per year compared to 493 per site if IFN-free therapy was freely available. There is capacity in the current health system to treat five times the numbers of patients with chronic HCV in Australia. When applying a weighted ratio; the results for all centres show a 3.6-fold increase in the capacity to treat with IFN-free regimens. However, these numbers may be an underestimate based on the first 3 months of actual treatment uptake since Pharmaceutical Benefits Scheme listing in March and May 2016. CONCLUSION: Although current sites have a significant capacity to increase rapidly HCV treatment numbers, expansion of treatment settings and new models of care and training may be required to deliver HCV treatment to all HCV-infected individuals. PMID- 27717118 TI - Diet-related gut bacterial dysbiosis correlates with impaired development, increased mortality and Nosema disease in the honeybee (Apis mellifera). AB - Dysbiosis, defined as unhealthy shifts in bacterial community composition, can lower the colonization resistance of the gut to intrinsic pathogens. Here, we determined the effect of diet age and type on the health and bacterial community composition of the honeybee (Apis mellifera). We fed newly emerged bees fresh or aged diets, and then recorded host development and bacterial community composition from four distinct regions of the hosts' digestive tract. Feeding fresh pollen or fresh substitute, we found no difference in host mortality, diet consumption, development or microbial community composition. In contrast, bees fed aged diets suffered impaired development, increased mortality and developed a significantly dysbiotic microbiome. The consumption of aged diets resulted in a significant reduction in the core ileum bacterium Snodgrassella alvi and a corresponding increase in intrinsic pathogen Frischella perrara. Moreover, the relative abundance of S. alvi in the ileum was positively correlated with host survival and development. The inverse was true for both F. perrara and Parasacharibacter apium. Collectively, our findings suggest that the early establishment of S. alvi is associated with healthy nurse development and potentially excludes F. perrara and P. apium from the ileum. Although at low abundance, establishment of the common midgut pathogen Nosema spp. was significantly associated with ileum dysbiosis and associated host deficiencies. Moreover, dysbiosis in the ileum was reflected in the rectum, mouthparts and hypopharyngeal glands, suggesting a systemic host effect. Our findings demonstrate that typically occurring alterations in diet quality play a significant role in colony health and the establishment of a dysbiotic gut microbiome. PMID- 27717119 TI - Comparison of acute expansion of bioresorbable vascular scaffolds versus metallic drug-eluting stents in different degrees of calcification: An Optical Coherence Tomography Study. AB - OBJECTIVES: The acute expansion of bioresorbable vascular scaffolds (BRS) and drug-eluting stents (DES) in lesions with different extent of calcification was compared by Optical Coherence Tomography (OCT). BACKGROUND: The acute mechanical performance of polymeric BRS in calcified lesions is poorly understood. METHODS: Acute device performance in lesions treated with either BRS(N = 50) or DES (N = 50) was compared using Optical Coherence Tomography (OCT). According to angiographic degree of calcification the lesions were divided in three groups: no/mild, moderate and heavy calcification. Device performance was assessed with the following parameters by OCT: mean scaffold area, eccentricity index (EI), symmetry index (SI) and percentage incomplete strut apposition (ISA). RESULTS: One hundred lesions from 85 patients (BRS/DES; 37/48) were analyzed. Scaffold area and SI were similar between BRS and DES groups in the three calcification subgroups. Compared to DES, EI in BRS was marginally lower in the no/mild calcification group (0.86 +/- 0.03 versus 0.88 +/- 0.03, p = 0.018) but was similar in the moderate and heavy calcification groups. Compared to DES, percentage ISA struts in BRS was similar in the no/mild calcification group and was significantly lower in the moderate and heavy calcification groups (2.96 +/- 2.36 versus 6.78 +/- 4.61%, p = 0.002 and 1.82 +/- 2.40 versus 8.89 +/- 8.25%, p = 0.025 respectively). CONCLUSIONS: With adequate lesion preparation, implantation of BRS in a population reflective of clinical practice, resulted in a similar luminal gain compared to DES as measured by OCT, regardless of the degree of angiographic calcification, while acute malapposition is lower with BRS in moderately and heavily calcified lesions. The clinical significance of our findings warrants further evaluation in future studies. (c) 2016 Wiley Periodicals, Inc.

AB - Highly conductive anion exchange membranes (AEMs), along with the ability to suppress swelling, are critical but challenging requirements for alkaline fuel cell applications. To achieve this criterion, a series of poly(ether sulfone)s (PESFs) with flexible alkyl imidazolium pendants attached directly on large planar 6,12-bis(4-hydroxyphenyl)-5,11-dihydroindolo[3,2-b]carbazole (DCP) units is reported. The planar DCP units stabilize the hydrophobic phase through strong pi-pi interactions and also facilitate the formation of ionic conducting channels through self assembly of hydrophilic pendants. The AEM prepared here, based on rational design, has a relatively low ion exchange capacity (IEC) of 1.86 * 10-3 mol g-1 and exhibits high hydroxide ion (OH- ) conductivity of 101 * 10-3 S cm-1 , a low swelling ratio of 9.3% and a water uptake of 39.6%. Furthermore, the AEMs reported in this paper have excellent stability in 1 m NaOH solution at 80 degrees C over 500 h. Therefore, the synthesized polymers offer a new insight into the design of high performance materials for AEMs. PMID- 27717121 TI - Molecular characterisation of two alpha-esterase genes involving chlorpyrifos detoxification in the diamondback moth, Plutella xylostella. AB - BACKGROUND: Carboxylesterases (CarEs) are involved in metabolic detoxification of dietary and environmental xenobiotics in insects. However, owing to the complexity of the protein family, the involvement of CarEs in insecticide metabolism in Plutella xylostella has not been fully elucidated. This study aimed to characterise two CarE genes and assess their potential roles in response to chlorpyrifos in P. xylostella. RESULTS: Synergistic tests showed that triphenyl phosphate decreased the resistance of the third-instar larvae to chlorpyrifos. The treatment of the third-instar larvae with chlorpyrifos at the LC30 dose led to a significant increase in CarE activity. Two CarE cDNAs (Pxae18 and Pxae28) were subsequently sequenced and characterised. Both genes were expressed predominantly in the larval midgut. Most importantly, two CarE genes showed significantly higher expression in the chlorpyrifos-resistant strain than in the susceptible strain. RNAi knockdown of Pxae18 and Pxae28 significantly increased the mortality to chlorpyrifos from 40% in the control to 73.8 and 63.3% respectively. CONCLUSION: RNAi knockdown of Pxae18 and Pxae28 significantly inhibited detoxification ability and increased the mortality in P. xylostella. The results indicate that these two CarE genes play important roles in the detoxification of chlorpyrifos in P. xylostella. (c) 2016 Society of Chemical Industry. PMID- 27717123 TI - Craniofacial morphology in pediatric patients with Prader-Willi syndrome: a retrospective study. AB - OBJECTIVE: To investigate craniofacial characteristics in pediatric patients with Prader-Willi syndrome (PWS). SETTING AND SAMPLE POPULATION: A retrospective sample of 20 consecutive patients with PWS who had lateral and antero-posterior (AP) cephalograms (14 males and six females; average age 10.2 +/- 3 years) was compared to 20 controls matched for age and sex (14 males and six females; average age 10.5 +/- 3.7 years). MATERIALS AND METHODS: Cephalometric skeletal measurements were performed twice at a 1-week interval by one calibrated operator, and random error was calculated using Dahlberg's formula. Mean values and standard deviations were computed for all variables. Student's t-test for independent samples was used to determine significant differences between PWS and controls. The level of significance was set at p < 0.05. RESULTS: Cephalometric values for the length of the maxilla (p < 0.01), mandibular length (p < 0.05) at both the ramus (p < 0.05) and the mandibular body (p < 0.01), and posterior and anterior facial height (p < 0.01) were significantly lower in patients with PWS compared to controls. The AP cephalometric analysis revealed a significant reduction (p < 0.01) in maxillary skeletal width, mandibular skeletal width, and interzygomatic distance. CONCLUSIONS: Pediatric patients with PWS seem to have a general reduction in certain craniofacial skeletal parameters (i.e., maxillary and mandibular length) compared to controls, but this study did not assess the overall craniofacial characteristics. PMID- 27717124 TI - Is colorectal surgery beyond the age of 80 still feasible with acceptable mortality? An analysis of the predictive value of CR-POSSUM and life expectancy after hospital discharge. AB - AIM: Increased morbidity and mortality could mitigate the positive effect of surgery in elderly patients undergoing colorectal resections. This retrospective study aims to describe early morbidity and mortality together with long-term survival in octogenarians and nonagenarians undergoing colorectal surgery. Predictors for in-hospital mortality are identified. The predictive value of CR POSSUM is assessed. METHOD: Data on consecutive patients 80 years old or more undergoing a colorectal resection in our centre from 2004 until 2010 were analysed. RESULTS: Some 286 patients [median age 84 years; interquartile range (IQR) 81.6-86.1; 133 men, 47%] underwent a colorectal resection. Median follow-up was 32 months (IQR 14.5-51.2). Two hundred and fifty-eight patients (90%) were operated on for malignancy. Only 64 patients (22.4%) underwent a laparoscopic procedure. Overall median hospital stay was 12 days (IQR 9.0-20.0) and in hospital mortality was 9.4%. Seventy-six per cent (n = 170) of patients could return home after discharge. The 1-year survival rate was 78.6% (95% CI 73.8 82.7). Median CR-POSSUM for in-hospital mortality was 12.6% (IQR 11.9-21.0). The concordance probability estimate was 0.668 (95% CI 0.609-0.728), reflecting a moderate predictive capacity of CR-POSSUM. Once patients had been discharged from hospital, life expectancy was similar to that of the Belgian general population. CONCLUSION: Colorectal surgery in octogenarians and nonagenarians resulted in a considerable in-hospital mortality of about 9%. One-year mortality added an additional 12%, which is in concordance with the overall life expectancy at that age.

PMID- 27717127 TI - Diverse Effects, Complex Causes: Children Use Information About Machines' Functional Diversity to Infer Internal Complexity. AB - Four studies explored the abilities of 80 adults and 180 children (4-9 years), from predominantly middle-class families in the Northeastern United States, to use information about machines' observable functional capacities to infer their internal, "hidden" mechanistic complexity. Children as young as 4 and 5 years old used machines' numbers of functions as indications of complexity and matched machines performing more functions with more complex "insides" (Study 1). However, only older children (6 and older) and adults used machines' functional diversity alone as an indication of complexity (Studies 2-4). The ability to use functional diversity as a complexity cue therefore emerges during the early school years, well before the use of diversity in most categorical induction tasks. PMID- 27717122 TI - Genetic variants in CETP increase risk of intracerebral hemorrhage. AB - OBJECTIVE: In observational epidemiologic studies, higher plasma high-density lipoprotein cholesterol (HDL-C) has been associated with increased risk of intracerebral hemorrhage (ICH). DNA sequence variants that decrease cholesteryl ester transfer protein (CETP) gene activity increase plasma HDL-C; as such, medicines that inhibit CETP and raise HDL-C are in clinical development. Here, we test the hypothesis that CETP DNA sequence variants associated with higher HDL-C also increase risk for ICH. METHODS: We performed 2 candidate-gene analyses of CETP. First, we tested individual CETP variants in a discovery cohort of 1,149 ICH cases and 1,238 controls from 3 studies, followed by replication in 1,625 cases and 1,845 controls from 5 studies. Second, we constructed a genetic risk score comprised of 7 independent variants at the CETP locus and tested this score for association with HDL-C as well as ICH risk. RESULTS: Twelve variants within CETP demonstrated nominal association with ICH, with the strongest association at the rs173539 locus (odds ratio [OR] = 1.25, standard error [SE] = 0.06, p = 6.0 * 10-4 ) with no heterogeneity across studies (I2 = 0%). This association was replicated in patients of European ancestry (p = 0.03). A genetic score of CETP variants found to increase HDL-C by ~2.85mg/dl in the Global Lipids Genetics Consortium was strongly associated with ICH risk (OR = 1.86, SE = 0.13, p = 1.39 * 10-6 ). INTERPRETATION: Genetic variants in CETP associated with increased HDL C raise the risk of ICH. Given ongoing therapeutic development in CETP inhibition and other HDL-raising strategies, further exploration of potential adverse cerebrovascular outcomes may be warranted.

AB - Programs of drug discovery generally exploit one enantiomer of a chiral compound for lead development following the principle that enantiomer recognition is central to biological specificity. However, chiral promiscuity has been identified for a number of enzyme families, which have shown that mirror-image packing can enable opposite enantiomers to be accommodated in an enzyme's active site. Reported here is a series of crystallographic studies of complexes between an enzyme and a potent experimental herbicide whose chiral center forms an essential part of the inhibitor pharmacophore. Initial studies with a racemate at 1.85 A resolution failed to identify the chirality of the bound inhibitor, however, by extending the resolution to 1.1 A and by analyzing high-resolution complexes with the enantiopure compounds, we determined that both enantiomers make equivalent pseudosymmetric interactions in the active site, thus mimicking an achiral reaction intermediate. PMID- 27717129 TI - Emergency Department Utilization in Children <36 Months Is Not an Independent Risk Factor for Maltreatment. AB - BACKGROUND AND OBJECTIVES: Early childhood high-frequency use (HFU) of the emergency department (ED) has been endorsed as a marker for increased risk of child maltreatment. In a prior analysis of pediatric ED (PED) visits by 16,664 children, 0-36 months old, we defined early childhood HFU (the 90th percentile) as five or more visits. The purpose of this study was to follow HFU patients to determine if they had a higher likelihood of reported maltreatment. METHODS: This is a single-center, cross-sectional, observational study of the association between PED use in early life and subsequent intervention by child protective services (CPS). CPS data were obtained from a Department of Social Services database for subjects meeting criteria for PED HFU as well as sex, race, and ethnicity-matched controls. Multivariable analyses were performed to assess if HFU was independently associated with child maltreatment. RESULTS: While CPS involvement was more highly represented in the group with PED HFU, so were many confounding variables such as African American race, history of hospital admissions, and social work consultations in the PED for any reason. HFU, by itself, is not a risk factor for a major intervention by CPS. CONCLUSIONS: In efforts to identify children at risk for maltreatment, objective assessments such as PED utilization are potential markers to utilize to aid in recognition. Unfortunately, there are many risk factors for increased PED utilization that act as confounders for this marker. Future work is necessary to identify children at risk for maltreatment in the ED. PMID- 27717126 TI - Near-normalization of glycaemic control with glucagon-like peptide-1 receptor agonist treatment combined with exercise in patients with type 2 diabetes. AB - AIMS: To investigate the effects of exercise in combination with a glucagon-like peptide-1 receptor agonist (GLP-1RA), liraglutide, or placebo for the treatment of type 2 diabetes. METHODS: Thirty-three overweight, dysregulated and sedentary patients with type 2 diabetes were randomly allocated to 16 weeks of either exercise and liraglutide or exercise and placebo. Both groups had three supervised 60-minute training sessions per week including spinning and resistance training. RESULTS: Glycated haemoglobin (HbA1c) levels dropped by a mean +/- standard deviation of 2.0% +/- 1.2% (from 8.2% +/- 1.4%) in the exercise plus liraglutide group vs 0.3% +/- 0.9% (from 8.0% +/- 1.2%) in the exercise plus placebo group ( P < .001), and body weight was reduced more with liraglutide ( 3.4 +/- 2.9 kg vs -1.6 +/- 2.3 kg; P < .001). Compared with baseline, similar reductions were seen in body fat (exercise plus liraglutide: -2.5% +/- 1.4% [ P < .001]; exercise plus placebo: -2.2% +/- 1.9% [ P < .001]) and similar increases were observed in maximum oxygen uptake (exercise plus liraglutide: 0.5 +/- 0.5 L O2 /min [ P < .001]; exercise plus placebo: 0.4 +/- 0.4 L O2 /min [ P = .002]). Greater reductions in fasting plasma glucose (-3.4 +/- 2.3 mM vs -0.3 +/- 2.6 mM, P < .001) and systolic blood pressure (-5.4 +/- 7.4 mm Hg vs -0.6 +/- 11.1 mm Hg, P < .01) were seen with exercise plus liraglutide vs exercise plus placebo. The two groups experienced similar increases in quality of life during the intervention. CONCLUSIONS: In obese patients with type 2 diabetes, exercise combined with GLP-1RA treatment near-normalized HbA1c levels and caused a robust weight loss when compared with placebo. These results suggest that a combination of exercise and GLP-1RA treatment is effective in type 2 diabetes. PMID- 27717131 TI - Directional Fluid Transport in Thin Porous Materials and its Functional Applications. AB - Directional fluid motion driven by the surface property of solid substrate is highly desirable for manipulating microfluidic liquid and collecting water from humid air. Studies on such liquid motion have been confined to dense material surfaces such as flat panels and single filaments. Recently, directional fluid transport through the thickness of thin porous materials has been reported by several research groups. Their studies not only attract fundamental, experimental and theoretical interest but also open novel application opportunities. This review article summarizes research progress in directional fluid transport across thin porous materials. It focuses on the materials preparation, basic properties associated with directional fluid transport in thin porous media, and their application development. The porous substrates, type of transporting fluids, structure-property attributes, and possible directional fluid transport mechanism are discussed. A perspective for future development in this field is proposed. PMID- 27717130 TI - Glucagon-like peptide-1 receptor agonists compared with basal insulins for the treatment of type 2 diabetes mellitus: a systematic review and meta-analysis. AB - AIMS: Since 2005, several glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been approved to treat people with type 2 diabetes. These agents are considered for use at the same point in the treatment paradigm as basal insulins. A comprehensive comparison of these drug classes, therefore, can help inform treatment decisions. This systematic review and meta-analysis assessed the clinical efficacy and safety of GLP-1 RAs compared with basal insulins. MATERIALS AND METHODS: MEDLINE, EMBASE, CENTRAL and PubMed databases were searched. Randomized clinical trials (RCTs) of >=16 weeks' duration comparing GLP-1 RAs vs basal insulins in adults with type 2 diabetes inadequately controlled with oral antihyperglycemic drugs were included. Data on the change from baseline to 26 weeks (+/-10 weeks) of treatment in hemoglobin A1c (HbA1c) and weight, as well as the proportion of patients experiencing hypoglycaemia, were extracted. Fixed effect pairwise meta-analyses were conducted where data were available from >=2 studies. RESULTS: Fifteen RCTs were identified and 11 were meta-analysed. The once-weekly GLP-1 RAs, exenatide long acting release (LAR) and dulaglutide, led to greater, statistically significant mean HbA1c reductions vs basal insulins (exenatide: -0.31% [95% confidence interval -0.42, -0.19], dulaglutide: -0.39% [ 0.49, -0.29]) whilst once-daily liraglutide and twice-daily exenatide did not (liraglutide: 0.06% [-0.06, 0.18], exenatide: 0.01% [-0.11, 0.13]). Mean weight reduction was seen with all GLP-1 RAs while mean weight gain was seen with basal insulins. Interpretation of the analysis of hypoglycaemia was limited by inconsistent definitions and reporting. Because of the limited number of available studies sensitivity analyses to explore heterogeneity could not be conducted. CONCLUSIONS: Although weight reduction is seen with all GLP-1 RA's, only the once-weekly agents, exenatide LAR and dulaglutide, demonstrate significant HbA1c reductions when compared to basal insulins.

AB - A novel unidirectional liquid spreading surface with an inclined arc pitted groove, inspired by the continuous unidirectional liquid spreading mechanism on the peristome surface of N. alata, is explored and fabricated by two-step UV lithography.

PMID- 27717134 TI - Ontogeny of modern human longitudinal body and transverse shoulder proportions. AB - OBJECTIVES: Whereas variation of modern human adult body size and shape has been widely studied in the context of ecogeographical clines, little is known about the differential growth patterns of transverse and longitudinal dimensions among human populations. Our study explored the ontogenetic variation of those body proportions in modern humans. METHODS: We compared results from four different approaches to study cross-sectional skeletal samples of Africans (n = 43), Amerindians (n = 69) and Europeans (n = 40) from 0 to 14 years of age. Clavicle, humerus, and femur intermetaphyseal lengths, and femoral distal metaphyseal breadth, were measured. Average ontogenetic trajectories were computed in order to compare the growth patterns of the three groups. RESULTS: Our findings demonstrated that the three geographical groups shared similar absolute and relative patterns of change with age for the four dimensions considered. Although interpopulation differences existed in transverse to longitudinal as well as in interlimb proportions, those differences did not seem to remain constant throughout ontogeny, similar to what has been shown for intralimb proportions. Growth rates of transverse shoulder proportions differed between populations from different regions after 10 years, whereas those for longitudinal proportions were very similar. CONCLUSIONS: The ontogeny of transverse shoulder proportions is more complex than what is observed for bi-iliac breadth, suggesting that transverse shoulder to limb proportions are not solely influenced by ecogeographical conditions. Our analysis demonstrates that methodologies that incorporate critical dimensions of body form could shed new light on human adaptation in both paleontological and neontological contexts. PMID- 27717133 TI - The fractionation of adipose tissue procedure to obtain stromal vascular fractions for regenerative purposes. AB - Autologous adipose tissue transplantation is clinically used to reduce dermal scarring and to restore volume loss. The therapeutic benefit on tissue damage more likely depends on the stromal vascular fraction of adipose tissue than on the adipocyte fraction. This stromal vascular fraction can be obtained by dissociation of adipose tissue, either enzymatically or mechanical. Enzymatic dissociation procedures are time-consuming and expensive. Therefore, we developed a new inexpensive mechanical dissociation procedure to obtain the stromal vascular fraction from adipose tissue in a time sparing way, which is directly available for therapeutic injection. This mechanical dissociation procedure is denoted as the fractionation of adipose tissue (FAT) procedure. The FAT procedure was performed in eleven patients. The composition of the FAT-stromal vascular fraction was characterized by immunohistochemistry. Adipose derived stromal cells isolated from the FAT-stromal vascular fraction were compared with adipose derived stromal cells isolated from nondissociated adipose tissue (control) for their CD-surface marker expression, differentiation and colony forming unit capacity. Case reports demonstrated the therapeutic effect of the FAT-stromal vascular fraction. The FAT-stromal vascular fraction is an enrichment of extracellular matrix containing a microvasculature and culturable adipose derived stromal cells. Adipose derived stromal cells isolated from FAT-stromal vascular fraction did not differ from adipose derived stromal cells isolated from the control group in CD-surface marker expression, differentiation and colony forming unit capacity. The FAT procedure is a rapid effective mechanical dissociation procedure to generate FAT-stromal vascular fraction ready for injection with all its therapeutic components of adipose tissue: it contains culturable adipose derived stromal cells embedded in their natural supportive extracellular matrix together with the microvasculature. PMID- 27717135 TI - Progress and development of analytical methods for gibberellins. AB - Gibberellins, as a group of phytohormones, exhibit a wide variety of bio functions within plant growth and development, which have been used to increase crop yields. Many analytical procedures, therefore, have been developed for the determination of the types and levels of endogenous and exogenous gibberellins. As plant tissues contain gibberellins in trace amounts (usually at the level of nanogram per gram fresh weight or even lower), the sample pre-treatment steps (extraction, pre-concentration, and purification) for gibberellins are reviewed in details. The primary focus of this comprehensive review is on the various analytical methods designed to meet the requirements for gibberellins analyses in complex matrices with particular emphasis on high-throughput analytical methods, such as gas chromatography, liquid chromatography, and capillary electrophoresis, mostly combined with mass spectrometry. The advantages and drawbacks of the each described analytical method are discussed. The overall aim of this review is to provide a comprehensive and critical view on the different analytical methods nowadays employed to analyze gibberellins in complex sample matrices and their foreseeable trends. PMID- 27717136 TI - The implicit sociometer effect and the moderating role of relational self construal. AB - The present study examined how negative feedback influenced implicit self evaluations and how individuals' level of relational self-construal (RelSC) moderated these relationships. One hundred Chinese university students completed the relational-interdependent self-construal scale and were randomly assigned into one of three conditions (social exclusion, personal failure, or control). After receiving the manipulation, participants completed two Brief Implicit Association Tests (BIATs) that measured their implicit self-liking and self competence. The results indicated that people with a highly RelSC typically had higher implicit self-liking, but they decreased their implicit self-liking more than those with a low RelSC after experiencing social exclusion. However, RelSC did not influence the effect of personal failure on implicit self-liking. In addition, RelSC was not associated with implicit self-competence in any situation. PMID- 27717137 TI - Corrosion-Activated Chemotherapeutic Function of Nanoparticulate Platinum as a Cisplatin Resistance-Overcoming Prodrug with Limited Autophagy Induction. AB - Despite nanoparticulate platinum (nano-Pt) has been validated to be acting as a platinum-based prodrug for anticancer therapy, the key factor in controlling its cytotoxicity remains to be clarified. In this study, it is found that the corrosion susceptibility of nano-Pt can be triggered by inducing the oxidization of superficial Pt atoms, which can kill both cisplatin-sensitive/resistance cancer cells. Direct evidence in the oxidization of superficial Pt atoms is validated to observe the formation of platinum oxides by X-ray absorption spectroscopy. The cytotoxicity is originated from the dissolution of nano-Pt followed by the release of highly toxic Pt ions during the corrosion process. Additionally, the limiting autophagy induction by nano-Pt might prevent cancer cells from acquiring autophagy-related drug resistance. With such advantages, the possibility of further autophagy-related drug resistance could be substantially reduced or even eliminated in cancer cells treated with nano-Pt. Moreover, nano Pt is demonstrated to kill cisplatin-resistant cancer cells not only by inducing apoptosis but also by inducing necrosis for pro-inflammatory/inflammatory responses. Thus, nano-Pt treatment might bring additional therapeutic benefits by regulating immunological responses in tumor microenvironment. These findings support the idea that utilizing nano-Pt for its cytotoxic effects might potentially benefit patients with cisplatin resistance in clinical chemotherapy. PMID- 27717138 TI - Mesoporous and Nanostructured TiO2 layer with Ultra-High Loading on Nitrogen Doped Carbon Foams as Flexible and Free-Standing Electrodes for Lithium-Ion Batteries. AB - A simple and green method is developed for the preparation of nanostructured TiO2 supported on nitrogen-doped carbon foams (NCFs) as a free-standing and flexible electrode for lithium-ion batteries (LIBs), in which the TiO2 with 2.5-4 times higher loading than the conventional TiO2 -based flexible electrodes acts as the active material. In addition, the NCFs act as a flexible substrate and efficient conductive networks. The nanocrystalline TiO2 with a uniform size of ~10 nm form a mesoporous layer covering the wall of the carbon foam. When used directly as a flexible electrode in a LIB, a capacity of 188 mA h g-1 is achieved at a current density of 200 mA g-1 for a potential window of 1.0-3.0 V, and a specific capacity of 149 mA h g-1 after 100 cycles at a current density of 1000 mA g-1 is maintained. The highly conductive NCF and flexible network, the mesoporous structure and nanocrystalline size of the TiO2 phase, the firm adhesion of TiO2 over the wall of the NCFs, the small volume change in the TiO2 during the charge/discharge processes, and the high cut-off potential contribute to the excellent capacity, rate capability, and cycling stability of the TiO2 /NCFs flexible electrode. PMID- 27717139 TI - Vps35-dependent recycling of Trem2 regulates microglial function. AB - Triggering receptor expressed on myeloid cells 2 (Trem2), an immune-modulatory receptor, is preferentially expressed in microglia of central nervous system. Trem2 might be involved in the development of Alzheimer's disease (AD) through regulating the inflammatory responses and phagocytosis of microglia. However, the intracellular trafficking of Trem2 remains unclear. In this study, we showed that Trem2 in the plasma membrane underwent endocytosis and recycling. Trem2 is internalized in a clathrin-dependent manner and then recycled back to the plasma membrane through vacuolar protein sorting 35 (Vps35), the key component of cargo recognition core of retromer complex, but not Rab11. When Vps35 is knocked down, Trem2 accumulated in the lysosomes but was not degraded. More importantly, Vps35 deficiency leads to excessive lipopolysaccharide (LPS)-induced inducible nitric oxide synthase (iNOS) expression and IL-6 production, which can be abolished by Trem2 overexpression. Furthermore, R47H Trem2, an AD-associated mutant, failed to interact with Vps35 and became unstable compared with wild-type Trem2. Our study suggests that Vps35/retromer is responsible for recycling of Trem2 in the regulation of microglial function such as proinflammatory responses, whereas R47H mutation impairs Trem2 trafficking, which might contribute to AD.

AB - The necessity for new sources for greener and cleaner energy production to replace the existing ones has been increasingly growing in recent years. Of those new sources, the hydrogen evolution reaction has a large potential. In this work, for the first time, MoSe2 /Mo core-shell 3D-hierarchical nanostructures are created, which are derived from the Mo 3D-hierarchical nanostructures through a low-temperature plasma-assisted selenization process with controlled shapes grown by a glancing angle deposition system. PMID- 27717141 TI - One-Step Microfluidic Fabrication of Polyelectrolyte Microcapsules in Aqueous Conditions for Protein Release. AB - We report a microfluidic approach for one-step fabrication of polyelectrolyte microcapsules in aqueous conditions. Using two immiscible aqueous polymer solutions, we generate transient water-in-water-in-water double emulsion droplets and use them as templates to fabricate polyelectrolyte microcapsules. The capsule shell is formed by the complexation of oppositely charged polyelectrolytes at the immiscible interface. We find that attractive electrostatic interactions can significantly prolong the release of charged molecules. Moreover, we demonstrate the application of these microcapsules in encapsulation and release of proteins without impairing their biological activities. Our platform should benefit a wide range of applications that require encapsulation and sustained release of molecules in aqueous environments. PMID- 27717142 TI - Structure-activity relationship of caffeic acid phenethyl ester analogs as new 5 lipoxygenase inhibitors. AB - Leukotrienes (LTs) are a class of lipid mediators implicated in numerous inflammatory disorders. Caffeic acid phenethyl ester (CAPE) possesses potent anti LTs activity through the inhibition of 5-lipoxygenase (5-LO), the key enzyme in the biosynthesis of LTs. In this study, we describe the design and synthesis of CAPE analogs as radical scavengers and 5-LO inhibitors. Caffeic esters bearing propargyl and allyl linkers between the caffeoyl and aryl moieties (4a-i and 5a i, respectively) were synthesized by Sonogashira and Heck cross-coupling reactions to probe the effects of flexibility and aryl substitution on 5-LO inhibition. Caffeoyl alcohol and ethers (6, 7a-b) as well as caffeoyl aldehyde and ketones (8a-e) were synthesized to elucidate the importance of the ester linkage for inhibitory activity. All tested compounds proved to be good radical scavengers (IC50 of 10-30 MUm). After preliminary anti-LTs activity screening in HEK293 cell models, 5-LO inhibition potential of selected compounds was determined in human polymorphonuclear leukocytes (PMNL). Most screened compounds outperformed CAPE 3 in concentration-dependent assays on PMNL, with ester dimers 4i and 5i along with caffeoyl ethers 7a-b being roughly eight-, seven-, and 16 fold more potent than Zileuton, with IC50 values of 0.36, 0.43, and 0.18 MUm, respectively. PMID- 27717143 TI - Assessment of analytical methods to determine pyrethroids content of bednets. AB - OBJECTIVE: To present and evaluate simple, cost-effective tests to determine the amount of insecticide on treated materials. METHODS: We developed and evaluated a competitive immunoassay on two different platforms: a label-free impedimetric biosensor (EIS biosensor) and a lateral flow. Both approaches were validated by gas chromatography (GC) and ELISA, gold standards for analytical methods and immunoassays, respectively. Finally, commercially available pyrethroid-treated ITN samples were analysed. Different extraction methods were evaluated. RESULTS: Insecticide extraction by direct infusion of the ITN samples with dichloromethane and dioxane showed recovery efficiencies around 100% for insecticide-coated bednets, and >70% for insecticide-incorporated bednets. These results were comparable to those obtained with standard sonication methods. The competitive immunoassay characterisation with ELISA presented a dynamic range between 12 nm and 1.5 MUm (coefficient of variation (CV) below 5%), with an IC50 at 138 nm, and a limit of detection (LOD) of 3.2 nm. EIS biosensor had a linear range between 1.7 nm and 61 nm (CV around 14%), with an IC50 at 10.4 nm, and a LOD of 0.6 nm. Finally, the lateral flow approach showed a dynamic range between 150 nm and 1.5 MUm, an IC50 at 505 nm and a LOD of 67 nm. CONCLUSIONS: ELISA can replace chromatography as an accurate laboratory technique to determine insecticide concentration in bednets. The lateral flow approach developed can be used to estimate ITN insecticide concentration in the field. This new technology, coupled to the new extraction methods, should provide reliable guidelines for ITN use and replacement in the field. PMID- 27717144 TI - An ex vivo porcine skin model to evaluate pressure-reducing devices of different mechanical properties used for pressure ulcer prevention. AB - Pressure ulcers are complex wounds caused by pressure- and shear-induced trauma to skin and underlying tissues. Pressure-reducing devices, such as dressings, have been shown to successfully reduce pressure ulcer incidence, when used in adjunct to pressure ulcer preventative care. While pressure-reducing devices are available in a range of materials, with differing mechanical properties, understanding of how a material's mechanical properties will influence clinical efficacy remains limited. The aim of this study was to establish a standardized ex vivo model to allow comparison of the cell protection potential of two gel like pressure-reducing devices with differing mechanical properties (elastic moduli of 77 vs. 35 kPa). The devices also displayed differing energy dissipation under compressive loading, and resisted strain differently under constant load in compressive creep tests. To evaluate biological efficacy we employed a new ex vivo porcine skin model, with a confirmed elastic moduli closely matching that of human skin (113 vs. 119 kPa, respectively). Static loads up to 20 kPa were applied to porcine skin ex vivo with subsequent evaluation of pressure-induced cell death and cytokine release. Pressure application alone increased the percentage of epidermal apoptotic cells from less than 2% to over 40%, and increased cellular secretion of the pro-inflammatory cytokine TNF-alpha. Co application of a pressure-reducing device significantly reduced both cellular apoptosis and cytokine production, protecting against cellular damage. These data reveal new insight into the relationship between mechanical properties of pressure-reducing devices and their biological effects. After appropriate validation of these results in clinical pressure ulcer prevention with all tissue layers present between the bony prominence and external surface, this ex vivo porcine skin model could be widely employed to optimize design and evaluation of devices aimed at reducing pressure-induced skin damage.

AB - Hydrophilic interaction liquid chromatography, an alternative liquid chromatography mode, is of particular interest in separating hydrophilic and polar ionic compounds. Compared with traditional liquid chromatography techniques, hydrophilic interaction liquid chromatography offers specific advantages mainly including: (1) relatively green and water-soluble mobile phase composition, which enhances the solubility of hydrophilic and polar ionic compounds; (2) no need for ion-pairing reagents and high content of organic solvent, which benefits mass spectrometry detection; (3) high orthogonality to reverse-phase liquid chromatography, well adapted to two-dimensional liquid chromatography for complicated samples. Therefore, hydrophilic interaction liquid chromatography has been rapidly developed in many areas over the past decades. This review summarizes the recent progress (from 2012 to July 2016) of hydrophilic interaction liquid chromatography in pharmaceutical analysis, with the focus on detecting chemical drugs in various matrices, charactering active compounds of natural products and assessing biotherapeutics through typical structure unit. Moreover, the retention mechanism and behavior of analytes in hydrophilic interaction liquid chromatography as well as some novel hydrophilic interaction liquid chromatography columns used for pharmaceutical analysis are also described.

However, some patients may show gains on several chromosomes simultaneously suggesting a hyperdiploid karyotype. OBJECTIVE: The objective of this study was to analyse by FISH the frequency and prognostic impact of hyperdiploidy in CLL. METHOD: A review of 1359 consecutive cases diagnosed with CLL referred for FISH analysis to a unique institution was carried out. Hyperdiploidy was considered when a gain of at least three of the five FISH probes used was observed. RESULTS: Seven cases (0.51%) with hyperdiploidy were found, confirming that it is a rare event in this disease. Although most patients presented with early Binet stages at diagnosis, six of seven (86%) shortly progressed. The median of time to the first therapy (TTFT) and overall survival (OS) for the patients with hyperdiploidy were short (1.4 months and 20 months, respectively). Moreover, comparing them with a control group of patients (non hyperdiploid) with completed follow-up data, TTFT and OS of the patients with hyperdiploidy were significantly shorter than the control group. CONCLUSION: The presence of hyperdiploidy is uncommon and probably associated with poor prognostic markers in CLL.

AB - A structure-determined silver nanocluster of [Ag10 (Eth)4 (CF3 COO)6 (CH3 OH)3 ].3C-H3 OH (Eth = ethisterone) (1), is firstly demonstrated by self-assembly of silver salt and ethisterone. Due to the thiophilicity of silver(I) ions, complex 1 shows reactivity with glutathione (GSH) molecules in solution and induces the fluorescence quenching behavior. Thus, complex 1 can be used as a fluorescent sensor for GSH. In consideration of the higher level of GSH in cancerous cells, complex 1 presents significant tumor suppression reactivity toward the human hepatocellular carcinoma (HepG2) cells with IC50 value of 165 * 10-9 m. Especially, complex 1 displays 3.4-fold higher in vitro cytotoxicity to HepG2 cells than that of the normal CCC-HEL-1 cells, which makes complex 1 a potential targeting suppression agent for cancerous cells. The molecular design of complex 1 not only generates a new medicine-silver(I) cluster family, but also opens a new avenue to the targeting anticancer organosilver(I) materials.

AB - A macrocyclic ruthenium(III) complex [RuIII (N2 O2 )Cl2 ]Cl (Ru-1) is reported as an inhibitor of angiogenesis and an anti-tumor compound. The complex is relatively non-cytotoxic towards endothelial and cancer cell lines in vitro, but specifically inhibited the processes of angiogenic endothelial cell tube formation and cancer cell invasion. Moreover, compared with known anti-cancer ruthenium complexes, Ru-1 is distinct in that it suppressed the expression of vascular endothelial growth factor receptor-2 (VEGFR2), and the associated downstream signaling that is crucial to tumor angiogenesis. In addition, in vivo studies showed that Ru-1 inhibited angiogenesis in a zebrafish model and suppressed tumor growth in nude mice bearing cancer xenografts.

AB - The budding yeast Saccharomyces cerevisiae has been a powerful model for the study of aging and has enabled significant contributions to our understanding of basic mechanisms of aging in eukaryotic cells. However, the laborious low throughput nature of conventional methods of performing aging assays limits the pace of discoveries in this field. Some of the technical challenges of conventional aging assay methods can be overcome by use of microfluidic systems coupled to time-lapse microscopy. One of the major advantages is the ability of a microfluidic system to perform long-term cell culture under well-defined environmental conditions while tracking individual yeast. Here, recent advancements in microfluidic platforms for various yeast-based studies including replicative lifespan assay, long-term culture and imaging, gene expression, and cell signaling are discussed. In addition, emerging problems and limitations of current microfluidic approaches are examined and perspectives on the future development of this dynamic field are presented. PMID- 27717152 TI - Toward Precision Medicine: A Cancer Molecular Subtyping Nano-Strategy for RNA Biomarkers in Tumor and Urine. AB - Cancer is a heterogeneous disease which manifests as different molecular subtypes due to the complex nature of tumor initiation, progression, and metastasis. The concept of precision medicine aims to exploit this cancer heterogeneity by incorporating diagnostic technology to characterize each cancer patient's molecular subtype for tailored treatments. To characterize cancer molecular subtypes accurately, a suite of multiplexed bioassays have currently been developed to detect multiple oncogenic biomarkers. Despite the reliability of current multiplexed detection techniques, novel strategies are still needed to resolve limitations such as long assay time, complex protocols, and difficulty in interpreting broad overlapping spectral peaks of conventional fluorescence readouts. Herein a rapid (80 min) multiplexed platform strategy for subtyping prostate cancer tumor and urine samples based on their RNA biomarker profiles is presented. This is achieved by combining rapid multiplexed isothermal reverse transcription-recombinase polymerase amplification (RT-RPA) of target RNA biomarkers with surface-enhanced Raman spectroscopy (SERS) nanotags for "one-pot" readout. This is the first translational application of a RT-RPA/SERS-based platform for multiplexed cancer biomarker detection to address a clinical need. With excellent sensitivity of 200 zmol (100 copies) and specificity, we believed that this platform methodology could be a useful tool for rapid multiplexed subtyping of cancers.

AB - During this work, a novel series of hydrophobic room temperature ionic liquids (ILs) based on five ether functionalized sulfonium cations bearing the bis{(trifluoromethyl)sulfonyl}imide, [NTf2 ]- anion were synthesized and characterized. Their physicochemical properties, such as density, viscosity and ionic conductivity, electrochemical window, along with thermal properties including phase transition behavior and decomposition temperature, have been measured. All of these ILs showed large liquid range temperature, low viscosity, and good conductivity. Additionally, by combining DFT calculations along with electrochemical characterization it appears that these novel ILs show good electrochemical stability windows, suitable for the potential application as electrolyte materials in electrochemical energy storage devices.

AB - INTRODUCTION AND OBJECTIVES: There are various recommendations for physical activity (PA). However agreement between all of these measures has not been established. Furthermore, given the challenges of measuring PA there is interest in evaluating whether a measure of exercise performance can be used as a surrogate measure to identify who is likely to achieve the recommendations. METHODS: A total of 184 people with COPD were recruited, 128 of which had complete data for these analyses. Participants wore the SenseWear Armband for 7 consecutive days and all performed an incremental shuttle walk test (ISWT). We extracted moderate to vigorous physical activity (MVPA) in bouts of >=10 min using a 3 metabolic equivalent (MET) threshold and an individually prescribed MET threshold (based on performance on the ISWT). Average daily step count and the physical activity level were also calculated. RESULTS: There was poor agreement between the four PA recommendations, with agreement on all four achieved in only 30 participants. People were least likely to be active using MVPA in >=10 min bouts using 3 MET threshold (21.1% active), and most likely to be active using MVPA in >=10 min bouts using an individually prescribed threshold (64.9% active). It was not possible to identify a threshold on the ISWT that would reliably predict those that achieved any of the four recommendations. CONCLUSION: Agreement between various physical activity recommendations is poor. This should be considered when measuring and describing physical activity adherence. The ISWT cannot be used to reliably predict adherence to physical activity guidelines. PMID- 27717154 TI - Application of testosterone to epitestosterone ratio to horse urine - a complementary approach to detect the administrations of testosterone and its pro drugs in Thoroughbred geldings. AB - Detection of testosterone and/or its pro-drugs in the gelding is currently regulated by the application of an international threshold for urinary testosterone of 20 ng/mL. The use of steroid ratios may provide a useful supplementary approach to aid in differentiating between the administration of these steroids and unusual physiological conditions that may result in atypically high testosterone concentrations. In the current study, an ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method was developed to quantify testosterone (T) and epitestosterone (E). The method was used to analyze 200 post-race urine samples from geldings in order to generate the ratios for the reference population. Following statistical analysis of the data, an upper limit of 5 for T:E ratio in geldings is proposed. Samples collected from 15 geldings with atypical urinary testosterone concentrations (>15 ng/mL) but otherwise normal steroid profile, had T:E ratios within those observed for the reference population. The applicability of an upper T:E ratio to detect an administration was demonstrated by the analysis of a selection of incurred samples from testosterone propionate, dehydroepiandrosterone (DHEA), and a mixture of DHEA and pregnenolone (Equi-Bolic(r)) administrations. These produced testosterone concentrations above the threshold of 20 ng/mL, but also T:E ratios above the proposed limit of 5. In conclusion, consideration of the T:E ratio appears to be a valuable complementary aid to evaluate whether an atypical testosterone concentration could be caused by a natural biological outlier as opposed to the administration of these steroids.

PMID- 27717156 TI - Combining arterial-spin labeling with functional magnetic resonance imaging measurement for characterizing patients with minimal hepatic encephalopathy. AB - AIM: Our objective is to explore key changes in brain functions in relation to minimal hepatic encephalopathy (MHE). We incorporated both resting-state functional magnetic resonance imaging (fMRI) and arterial spin labeling (ASL) to enhance the detection of MHE. METHODS: We undertook fMRI scanning for 56 MHE patients and 66 healthy controls. Region functional connectivity was carried out to assess the connectivity status between pairs of regions among 90 brain regions. Additionally, blood flow (BF) status was measured by ASL for all subjects. Spearman's correlation test was implemented to identify any correlation among z-values, results from number connection test type A, and digit symbol tests. Finally, the receiver operating characteristic curve was generated for assessing the accuracy of BF in MHE diagnosis. RESULTS: The corresponding functional connectivity was significantly different between MHE and control groups in 15 regions. For MHE patients, BF showed an increasing pattern in regions of interest. Blood flood in the putamen was positively correlated with number connection test type A neuropsychological performance, whereas it was negatively correlated with the digit symbol test. Blood flood in the right putamen showed the highest value of area under the curve with a sensitivity of 85.7% and specificity of 89.4%. CONCLUSION: Connectivity impairment resulting from ganglia-thalamo-cortical circuits may play important roles in mediating the development of MHE patients. An increase in the BF, particularly in the right putamen, may be considered as evidence for the presence of MHE. PMID- 27717157 TI - Inner Conflicts From a Resident Medicolegal Consulting Case. PMID- 27717155 TI - Genomic distribution and estimation of nucleotide diversity in natural populations: perspectives from the collared flycatcher (Ficedula albicollis) genome. AB - Properly estimating genetic diversity in populations of nonmodel species requires a basic understanding of how diversity is distributed across the genome and among individuals. To this end, we analysed whole-genome resequencing data from 20 collared flycatchers (genome size ~1.1 Gb; 10.13 million single nucleotide polymorphisms detected). Genomewide nucleotide diversity was almost identical among individuals (mean = 0.00394, range = 0.00384-0.00401), but diversity levels varied extensively across the genome (95% confidence interval for 200-kb windows = 0.0013-0.0053). Diversity was related to selective constraint such that in comparison with intergenic DNA, diversity at fourfold degenerate sites was reduced to 85%, 3' UTRs to 82%, 5' UTRs to 70% and nondegenerate sites to 12%. There was a strong positive correlation between diversity and chromosome size, probably driven by a higher density of targets for selection on smaller chromosomes increasing the diversity-reducing effect of linked selection. Simulations exploring the ability of sequence data from a small number of genetic markers to capture the observed diversity clearly demonstrated that diversity estimation from finite sampling of such data is bound to be associated with large confidence intervals. Nevertheless, we show that precision in diversity estimation in large outbred population benefits from increasing the number of loci rather than the number of individuals. Simulations mimicking RAD sequencing showed that this approach gives accurate estimates of genomewide diversity. Based on the patterns of observed diversity and the performed simulations, we provide broad recommendations for how genetic diversity should be estimated in natural populations. PMID- 27717159 TI - Solubility of Organosolv Lignin in gamma-Valerolactone/Water Binary Mixtures. AB - The solubility of lignin in a mixture of gamma-valerolactone (GVL) and water at different weight ratios was measured using the Hildebrand solubility parameters. Based on the molecular structure of lignin, its solubility parameter (delta value) was calculated as 25.5 MPa1/2 . The delta-value for aqueous GVL solvent increased from 23.1 MPa1/2 for pure GVL to 45.6 MPa1/2 for pure water. Therefore, the lignin solubility was predicted to increase with increasing GVL concentration in the aqueous mixture up to approximately 92-96 wt % of GVL. A ternary diagram describing the phase behavior of water-GVL-lignin mixtures at room temperature was constructed based on the experimental results. The three-component system exhibited a complex behavior with a liquid-liquid and solid-liquid-liquid phase split. The efficiency of the selected fractionation trials in a previous work was validated using the ternary solubility diagram. A promising recovery pathway and lignin isolation method were deduced from the results of this work.

AB - Polymorphism is a common property of amyloid fibers that complicates their detailed structural and functional studies. Here we report experiments illustrating the chemical principles that enable the formation of amyloid polymorphs with distinct stoichiometric composition. Using appropriate covalent tethering we programmed self-assembly of a model peptide corresponding to the [20 41] fragment of human beta2-microglobulin into fibers with either trimeric or dimeric amyloid cores. Using a set of biophysical and biochemical methods we demonstrated their distinct structural, morphological, and templating properties. Furthermore, we showed that supramolecular approaches in which the peptide is modified with bulky substituents can also be applied to modulate the formation of different fiber polymorphs. Such strategies, when applied to disease-related peptides and proteins, will greatly help in the evaluation of the biological properties of structurally distinct amyloids. PMID- 27717161 TI - The problem Of muscle hypertrophy: Revisited. AB - In this paper we revisit a topic originally discussed in 1955, namely the lack of direct evidence that muscle hypertrophy from exercise plays an important role in increasing strength. To this day, long-term adaptations in strength are thought to be primarily contingent on changes in muscle size. Given this assumption, there has been considerable attention placed on programs designed to allow for maximization of both muscle size and strength. However, the conclusion that a change in muscle size affects a change in strength is surprisingly based on little evidence. We suggest that these changes may be completely separate phenomena based on: (1) the weak correlation between the change in muscle size and the change in muscle strength after training; (2) the loss of muscle mass with detraining, yet a maintenance of muscle strength; and (3) the similar muscle growth between low-load and high-load resistance training, yet divergent results in strength.

AB - The complexity of the water oxidation reaction makes understanding the role of individual catalytic sites critical to improving the process. Here, size-selected 27-atom cobalt clusters (Co27 ) deposited on hematite (Fe2 O3 ) anodes were tested for water oxidation activity. The uniformity of these anodes allows measurement of the activity of catalytic sites of well-defined nuclearity and known density. Grazing incidence X-ray absorption near-edge spectroscopy (GIXANES) characterization of the anodes before and after electrochemical cycling demonstrates that these Co27 clusters are stable to dissolution even in the harsh water oxidation electrochemical environment. They are also stable under illumination at the equivalent of 0.4 suns irradiation. The clusters show turnover rates for water oxidation that are comparable or higher than those reported for Pd- and Co-based materials or for hematite. The support for the Co27 clusters is Fe2 O3 grown by atomic layer deposition on a Si chip. We have chosen to deposit a Fe2 O3 layer that is only a few unit cells thick (2 nm), to remove complications related to exciton diffusion. We find that the electrocatalytic and the photoelectrocatalytic activity of the Co27 /Fe2 O3 material is significantly improved when the samples are annealed (with the clusters already deposited). Given that the support is thin and that the cluster deposition density is equivalent to approximately 5 % of an atomic monolayer, we suggest that annealing may significantly improve the exciton diffusion from the support to the catalytic moiety. PMID- 27717162 TI - Embryonic hypocellularity, blastogenetic malformations, and fetal growth restriction. AB - An association between congenital malformations and fetal growth restriction (FGR) can be largely explained by a relationship with early embryonic hypocellularity. The malformations include the VACTERL association, which is exceptional as a Mendelian syndrome, but is commonly associated with monozygotic twinning, maternal diabetes, and some forms of aneuploidy, all characterized by a small embryo early in development. Parsimony suggests that these different links to VACTERL are related to the hypocellularity as a single common factor, rather than as an expression of three independent pathogenetic processes. A distinct non genetic pathogenesis is further supported by increased frequencies in the same conditions of a single umbilical artery (SUA), which is also unusual in Mendelian disorders. SUA often involves the atrophy of one artery, which may be facilitated by altered hemodynamics in a smaller embryo, providing a direct link to hypocellularity. Hypocellularity may also explain a possible connection between VACTERL and certain mitochondrial disorders, where reduced energy might slow early cell division and growth, reducing the size of the embryo.

AB - BACKGROUND: The non-target effect of Bacillus thuringiensis (Bt) toxins in aquatic ecosystems is crucial to improve the present assessment of Bt-transgenic plants, particularly where crops are cultivated near aquatic ecosystems. We conducted decomposition experiments during two growing seasons to determine the effects of Bt-transgenic rice litter with and without insecticide application on the meiobenthos communities in a field ditch. RESULTS: The community composition of meiobenthos colonised on leaf litter was not significantly different between Bt and non-Bt rice. The abundance of meiobenthos colonising leaves differed between insecticide application and control, and this insecticide effect interacted with rice type. No Bt toxin was detected in field ditch water. Leaf decomposition and nutrient content were comparable for both Bt and non-Bt rice with or without insecticide application. CONCLUSION: Bt-transgenic rice litter had no effect on the meiobenthos community composition in field ditches, but the chronic persistence of transgenic litter in nature needs to be taken into account at large scales in aquatic ecosystems.

AB - Mucus-penetrating nanosuspensions, consisting of pure hydrophobic therapeutics with dense muco-inert coatings that enable particles to effectively bypass the mucus barrier, demonstrate superior drug distribution and absorption at mucosal surfaces.

PMID- 27717165 TI - Preoperative direct bilirubin to prothrombin time ratio index to prevent liver failure after minor hepatectomy. AB - BACKGROUND: The most reliable index to predict the safety of hepatectomy for patients with poor liver function remains unknown. We aimed to construct a novel preoperative index to predict early liver failure (ELF) and mortality due to recurrence-free liver failure (MLF) after hepatectomy. METHODS: Between 2000 and 2012, 385 consecutive patients with hepatocellular carcinoma undergoing curative minor hepatectomy were divided into two sequential cohorts: training set (n = 143) and validation set (n = 242), and observed until 2015. RESULTS: Prothrombin time and direct bilirubin were independent predictors of both ELF and MLF in the training set. Thus we devised a novel index, the direct bilirubin to prothrombin time ratio index (DBPTRI). The areas under ROC curves of DBPTRI for predicting ELF and MLF were 0.78 and 0.93, respectively, in the validation set. Using a preoperative DBPTRI cut off of 4.2, we accurately predicted ELF and MLF in 86.8% and 88.4% of patients, respectively. DBPTRI was the best predictor of ELF and MLF when compared with conventional indices such as ICG-R15 and Child-Pugh score. Moreover, the 5-year overall survival rates of the patients with low and high DBPTRI were 59% and 36%, respectively (P < 0.0001). CONCLUSIONS: DBPTRI may serve as a simple, non-invasive index for estimating liver failure after hepatectomy. PMID- 27717166 TI - Mechanism for odd-electron anion generation of dihydroxybenzoic acid isomers in matrix-assisted laser desorption/ionization mass spectrometry with density functional theory calculations. AB - RATIONALE: Proton and radical are transferred between matrices and matrix and analyte in matrix-assisted laser desorption/ionization (MALDI) and these transfers drive ionization of analytes. The odd-electron anion [M-2H]*- was generated in dihydroxybenzoic acids (DHBs) and the ion abundance of the 2,5-DHB was the highest among six DHB isomers. We were interested in the mechanism of the ion generation of the odd-electron anion. METHODS: The observed [M-2H]*- and [M 3H]- ions, which were generated with the hydrogen radical removed from the phenolic hydroxyl groups (OH) in DHB isomers, were analyzed using negative-ion MALDI-MS. The enthalpy for ion generation and their stable structures were calculated using the density functional theory (DFT) calculation program Gaussian 09 with the B3LYP functional and the 6-31+G(d) basis set. RESULTS: The number of observed [M-2H]*- and [M-3H]- ions of the DHB isomers was dependent on the positions of the phenolic OH groups in the DHB isomers because the carboxy group interacts with the ortho OH group due to neighboring group participation, as confirmed from the stable structures of the [M-2H]*- anions calculated with the Gaussian 09 program. The DHB isomers were placed into three categories according to the number of the ions. CONCLUSIONS: Odd-electron anions ([M-2H]*- ) and [M 2H* -H]- ([M-3H]- ) ions were generated from DHB isomers due to removal of the hydrogen radical from the phenolic groups. The enthalpy for ion generation revealed that ion formation proceeds via a two-step pathway through the [M-M]- ion as an intermediate. (c) 2016 The Authors.

AB - In this work we systematically investigated the role of reduced graphene oxide (rGO) in hybrid perovskite solar cells (PSCs). By mixing rGO within the mesoporous TiO2 (m-TiO2 ) matrix, highly efficient solar cells with power conversion efficiency values up to 19.54 % were realized. In addition, the boosted beneficial role of rGO with and without Li-treated m-TiO2 is highlighted, improving transport and injection of photoexcited electrons. This combined system may pave the way for further development and optimization of electron transport and collection in high efficiency PSCs. PMID- 27717170 TI - Changes in the rumen microbiome and metabolites reveal the effect of host genetics on hybrid crosses. AB - The rumen microbiota plays important roles in nutrient metabolism and absorption of the host. However, it is poorly understood how host genetic variation shapes the community structure of the rumen microbiota and its metabolic phenotype. Here, we used sika deer (Cervus nippon) and elk (Cervus elaphus) to produce the following two types of hybrid offspring: sika deer ? * elk ? (SEH) and elk ? * sika deer ? (ESH). Then, we examined the rumen microbiome and metabolites in the parents and their hybrid offspring. The rumen microbiota in the hybrids differed from that in their parents, suggesting a significant effect of host genetics on the rumen microbiome that may have resulted from vertical transmission. The rumen metabolites displayed patterns similar to the structure of the rumen microbiome, with changes in the amounts of volatile fatty acids and metabolites of amino acids. The alanine, arginine, proline and phenylalanine pathways were enriched in the rumen of hybrid animals. The enriched metabolites in the above pathways were positively correlated with the bacteria Prevotella spp., Acetitomaculum spp., Quinella spp., Succinivibrio spp. and Ruminobacter spp. These results suggest that host genetics has a major impact on the rumen microbiome and metabolites in hybrid animals. PMID- 27717169 TI - 5HT2A receptor blockade in dorsomedial striatum reduces repetitive behaviors in BTBR mice. AB - Restricted and repetitive behaviors are a defining feature of autism, which can be expressed as a cognitive flexibility deficit or stereotyped, motor behaviors. There is limited knowledge about the underlying neuropathophysiology contributing to these behaviors. Previous findings suggest that central 5HT2A receptor activity is altered in autism, while recent work indicates that systemic 5HT2A receptor antagonist treatment reduces repetitive behaviors in an idiopathic model of autism. 5HT2A receptors are expressed in the orbitofrontal cortex and striatum. These two regions have been shown to be altered in autism. The present study investigated whether 5HT2A receptor blockade in the dorsomedial striatum or orbitofrontal cortex in the BTBR mouse strain, an idiopathic model of autism, affects the phenotype related to restricted and repetitive behaviors. Microinfusion of the 5HT2A receptor antagonist, M100907 into the dorsomedial striatum alleviated a reversal learning impairment and attenuated grooming behavior. M100907 infusion into the orbitofrontal cortex increased perseveration during reversal learning and potentiated grooming. These findings suggest that increased 5HT2A receptor activity in the dorsomedial striatum may contribute to behavioral inflexibility and stereotyped behaviors in the BTBR mouse. 5HT2A receptor signaling in the orbitofrontal cortex may be critical for inhibiting a previously learned response during reversal learning and expression of stereotyped behavior. The present results suggest which brain areas exhibit abnormalities underlying repetitive behaviors in an idiopathic mouse model of autism, as well as which brain areas systemic treatment with M100907 may principally act on in BTBR mice to attenuate repetitive behaviors. PMID- 27717171 TI - Light quality and quantity regulate aerobic methane emissions from plants. AB - Studies have been mounting in support of the finding that plants release aerobic methane (CH4 ), and that these emissions are increased by both short-term and long-term environmental stress. It remains unknown whether or not they are affected by variation in light quantity and quality, whether emissions change over time, and whether they are influenced by physiological parameters. Light is the primary energy source of plants, and therefore an important regulator of plant growth and development. Both shade-intolerant sunflower and shade-tolerant chrysanthemum were investigated for the release of aerobic CH4 emissions, using either low or high light intensity, and varying light quality, including control, low or normal red:far-red ratio (R:FR), and low or high levels of blue, to discern the relationship between light and CH4 emissions. It was found that low levels of light act as an environmental stress, facilitating CH4 release from both species. R:FR and blue lights increased emissions under low light, but the results varied with species, providing evidence that both light quantity and quality regulate CH4 emissions. Emission rates of 6.79-41.13 ng g-1 DW h-1 and 18.53-180.25 ng g-1 DW h-1 were observed for sunflower and chrysanthemum, respectively. Moreover, emissions decreased with age as plants acclimated to environmental conditions. Since effects were similar in both species, there may be a common trend among a number of shade-tolerant and shade-intolerant species. Light quantity and quality are influenced by factors including cloud covering, so it is important to know how plants will be affected in the context of aerobic CH4 emissions. PMID- 27717172 TI - Comparative genomics and physiology of the butyrate-producing bacterium Intestinimonas butyriciproducens. AB - Intestinimonas is a newly described bacterial genus with representative strains present in the intestinal tract of human and other animals. Despite unique metabolic features including the production of butyrate from both sugars and amino acids, there is to date no data on their diversity, ecology, and physiology. Using a comprehensive phylogenetic approach, Intestinimomas was found to include at least three species that colonize primarily the human and mouse intestine. We focused on the most common and cultivable species of the genus, Intestinimonas butyriciproducens, and performed detailed genomic and physiological comparison of strains SRB521T and AF211, isolated from the mouse and human gut respectively. The complete 3.3-Mb genomic sequences of both strains were highly similar with 98.8% average nucleotide identity, testifying to their assignment to one single species. However, thorough analysis revealed significant genomic rearrangements, variations in phage-derived sequences, and the presence of new CRISPR sequences in both strains. Moreover, strain AF211 appeared to be more efficient than strain SRB521T in the conversion of the sugars arabinose and galactose. In conclusion, this study provides genomic and physiological insight into Intestinimonas butyriciproducens, a prevalent butyrate-producing species, differentiating strains that originate from the mouse and human gut.

AB - Graphitic carbon nitride (g-C3 N4 ) has been widely used in fields related to energy and materials science. However, nanostructured g-C3 N4 photocatalysts synthesized by traditional thermal polycondensation methods have the disadvantage of small specific surface areas and wide band gaps; these limit the catalytic activity and application range of g-C3 N4 . Based on the unique nanostructure of g-C3 N4 , it is a feasible method to modify g-C3 N4 with metals to design novel metal-semiconductor composites. Metals alter the photochemical properties of g-C3 N4 , in particular, narrow the band gap and expand photoabsorption into the visible range, which improves the photocatalytic performance. This review covers recent progress in metal/g-C3 N4 nanocomposites for photocatalysts, organic systems, biosensors, and so on. The aim is to summarize the synthetic methods, nanostructures, and applications of metal/g-C3 N4 nanocomposite materials, as well as discuss future research directions in these areas.

AB - Inspired by the transparent hair layer on water plants Salvinia and Pistia, superhydrophobic flexible thin films, applicable as transparent coatings for optoelectronic devices, are introduced. Thin polymeric nanofur films are fabricated using a highly scalable hot pulling technique, in which heated sandblasted steel plates are used to create a dense layer of nano- and microhairs surrounding microcavities on a polymer surface. The superhydrophobic nanofur surface exhibits water contact angles of 166 +/- 6 degrees , sliding angles below 6 degrees , and is self-cleaning against various contaminants. Additionally, subjecting thin nanofur to argon plasma reverses its surface wettability to hydrophilic and underwater superoleophobic. Thin nanofur films are transparent and demonstrate reflection values of less than 4% for wavelengths ranging from 300 to 800 nm when attached to a polymer substrate. Moreover, used as translucent self-standing film, the nanofur exhibits transmission values above 85% and high forward scattering. The potential of thin nanofur films for extracting substrate modes from organic light emitting diodes is tested and a relative increase of the luminous efficacy of above 10% is observed. Finally, thin nanofur is optically coupled to a multicrystalline silicon solar cell, resulting in a relative gain of 5.8% in photogenerated current compared to a bare photovoltaic device. PMID- 27717177 TI - Nanostructured Bifunctional Redox Electrocatalysts. AB - Electrocatalysts are playing a prominent role in the design of renewable energy devices. Benefiting from a long and prosperous history of synthesizing individual hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) electrocatalysts, the development of bifunctional ORR/OER or HER/OER electrocatalysts has recently emerged as a new research hotspot. In this review, a brief account of recent developments of bifunctional electrocatalysts for ORR/OER and HER/OER are introduced, aiming to provide insights into theoretical understanding of these reactions through analysis and comparison of various bifunctional electrocatalysts. The related reaction mechanisms and the associated activity descriptors for aforementioned reactions in the recent literatures are also presented. Different series of bifunctional electrocatalysts with much improved performances are discussed in detail and their design principles are outlined. Finally, the existing challenges and the future effort directions for enhancing the performance of bifunctional electrocatalysts are proposed.

AB - BACKGROUND: Caribbean fruit fly (Caribfly) is a serious economic insect pest because of development of larvae that hatch from eggs oviposited into fruits by female adults. This study assessed the virulence of twelve entomopathogenic nematode (EPN) isolates to Caribfly in laboratory bioassays as a starting point toward evaluation of management strategies for the fruit-to-soil-dwelling stages of A. suspensa in fields infested by Caribfly. RESULTS: Inoculation of A. suspensa with 1 mL of ca 200 IJs larva-1 killed Caribfly at either larval or pupal stage. Pupae were more resistant to EPN infections than larvae. Adult emergence from inoculated pupae in soil microcosms was significantly lower than that observed in filter paper assays. Longest or largest steinernematids suppressed emergence of more adult Caribfly from pupae in soils, whereas shorter heterorhabditids were more infectious to Caribfly larvae. The highest mortalities of A. suspensa were caused by exotic nematodes Steinernema feltiae and Heterorhabditis bacteriophora, followed by the native Heterorhabditis indica and the exotic Steinernema carpocapsae. CONCLUSION: Entomopathogenic nematodes reduced the development of Caribfly larvae and pupae to adult in our bioassays, suggesting that EPNs have potential for biological control of A. suspensa. Future work will assess management strategies, using the virulent EPNs, in orchards infested by A. suspensa. (c) 2016 Society of Chemical Industry.

AB - Small interfering RNA (siRNA) delivered from reactive oxygen species-degradable tissue engineering scaffolds promotes diabetic wound healing in rats. Porous poly(thioketal-urethane) scaffolds implanted in diabetic wounds locally deliver siRNA that inhibits the expression of prolyl hydroxylase domain protein 2, thereby increasing the expression of progrowth genes and increasing vasculature, proliferating cells, and tissue development in diabetic wounds. PMID- 27717179 TI - Theoretical Investigation and Design of Highly Efficient Blue Phosphorescent Iridium(III) Complexes Bearing Fluorinated Aromatic Sulfonyl Groups. AB - Aromatic sulfonyl groups have attracted increasing interest due to their unique electronic features. In this article, a series of IrIII complexes bearing fluorinated phenylsulfonyl groups were evaluated by density functional theory and time-dependent density functional theory methods. To explore their phosphorescence efficiencies, factors that determine the radiative decay rate constant, kr , and the nonradiative decay rate constant, knr , were computed. As demonstrated by the results, complex 4, which has fluorinated phenylsulfonyl groups at the 5-positions of the phenyl rings for all three C^N ligands, was found to have the highest phosphorescence efficiencies with the largest kr and smallest knr values among these complexes. Moreover, it was found to exhibit significantly blueshifted behavior relative to complex 1 and emits in the blue region, and thus, it can serve as a highly efficient blue emitter for application in organic light-emitting diodes. These findings successfully illustrated the structure-properties relationship and provided valuable information for the development of future highly efficient blue-emitting phosphors. PMID- 27717180 TI - Does obesity influence the subgingival microbiota composition in periodontal health and disease? AB - AIM: To evaluate whether obesity affects the subgingival microbial composition of patients with periodontal health or chronic periodontitis (CP). MATERIALS AND METHODS: Based on periodontal parameters, body mass index and waist-hip ratio, 166 patients were allocated into one of the following groups: Normal weight (NW) patients with periodontal health (n = 44), NW patients with CP (n = 40), obese patients with periodontal health (n = 40) and obese patients with CP (n = 42). Six subgingival biofilm samples per patient were analysed for their content of 40 bacterial species using checkerboard DNA-DNA hybridization. RESULTS: Obese patients with CP harboured higher levels and/or higher proportions of several periodontal pathogens than those with NW and CP, including Aggregatibacter actinomycetemcomitans, Eubacterium nodatum, Fusobacterium nucleatum ss vincentii, Parvimonas micra, Prevotella intermedia, Tannerella forsythia, Prevotella melaninogenica and Treponema socranskii. The proportions of most of these pathogens, as well Campylobacter rectus and Eikenella corrodens, were more increased in the diseased sites of the obese patients than in those with NW. Furthermore, the healthy sites of the obese patients, presenting or not CP, also exhibited higher proportions of some of the pathogens than patients with NW. CONCLUSIONS: Obesity is associated with increased levels and proportions of periodontal pathogens, especially in patients with CP.

AB - Aligned poly(l-lactide)/poly(methyl methacrylate) binary blend fibers and mats loaded with a chimeric green fluorescence protein having a bioactive peptide with hydroxyapatite binding and mineralization property are prepared by pressurized gyration. The effect of processing parameters on the product morphologies, and the shape memory properties of these samples are investigated. Integration of hydroxyapatite nanoparticles into the fiber assembly is self-directed using the hydroxyapatite-binding property of the peptide genetically engineered to green fluorescence protein. Fluorescence microscopy analysis corroborated with Fourier transform infrared spectroscopy (FTIR) data confirms the integration of the chimeric protein with the fibers. An enzyme based remineralization assay is conducted to study the effects of peptide-mediated mineralization within the fiber mats. Raman and FTIR spectral changes observed following the peptide mediated mineralization provides an initial step toward a soft-hard material transition. These results show that programmable shape memory properties can be obtained by incorporating genetically engineered bioactive peptide domains into polymer fibers. PMID- 27717182 TI - Atg1-independent induction of autophagy by the Drosophila Ulk3 homolog, ADUK. AB - Although canonical autophagy regulation requires a multi-protein complex centered on the Ser/Thr-kinase Atg1 (mammalian Ulk1/2), alternative signals can induce autophagy independent of Atg1 through unknown mechanisms. Here we identify the Drosophila Ulk3 ortholog, another Drosophila Unc-51-like kinase (ADUK), as an Atg1-independent autophagy inducer. ADUK interacts with Atg1 complex members Atg13 and 200 kDa FAK family kinase-interacting protein, and requires Atg13 but not Atg1 for autophagy induction. Loss of ADUK shortens adult lifespan and reduces the autophagic response to a chemical stressor, dimethyl sulfoxide. However, ADUK is not required for autophagy induction by Atg1-dependent nutrient or developmental cues. Atg1 and ADUK/Ulk3 thus represent alternative catalytic components of a shared autophagy kinase complex. PMID- 27717183 TI - Design, synthesis, and biological evaluation of novel tetrahydroisoquinoline derivatives as potential antitumor candidate. AB - A novel class of tetrahydroisoquinoline derivatives was designed and synthesized as antitumor agents and evaluated for their in vitro and in vivo biological activities. The antiproliferative activities of all the target compounds on HUVEC, MCF-7, and HT-29 were evaluated. Compared with colchicine (1.04 * 10-2 MUm), 17d and 17e exhibited outstanding activity on MCF-7 with IC50 values 0.26 * 10-2 MUm and 0.89 * 10-3 MUm in cell cytotoxicity assay. The tubulin polymerization assay demonstrated that 17d and 17e exhibited better inhibition rate. In the MCF-7-xenograft mouse model that was treated with 17d and 17e by intraperitoneal injection, the tumor weight was decreased at same rate with tamoxifen, and relative tumor proliferation rates were 59.48% and 41.33%, while tamoxifen was 45.08% with a daily dose of 20 mg/kg, which were demonstrated potent in vivo efficacy. PMID- 27717185 TI - Ultrasonic Cavitation Induced Shape-Memory Effect in Porous Polymer Networks. AB - Inspired by the application of ultrasonic cavitation based mechanical force (CMF) to open small channels in natural soft materials (skin or tissue), it is explored whether an artificial polymer network can be created, in which shape-changes can be induced by CMF. This concept comprises an interconnected macroporous rhodium phosphine (Rh-P) coordination polymer network, in which a CMF can reversibly dissociate the Rh-P microphases. In this way, the ligand exchange of Rh-P coordination bonds in the polymer network is accelerated, resulting in a topological rearrangement of molecular switches. This rearrangement of molecular switches enables the polymer network to release internal tension under ultrasound exposure, resulting in a CMF-induced shape-memory capability. The interconnected macroporous structure with thin pore walls is essential for allowing the CMF to effectively permeate throughout the polymer network. Potential applications of this CMF-induced shape-memory polymer can be mechanosensors or ultrasound controlled switches. PMID- 27717184 TI - Nuclear phosphoproteome analysis of 3T3-L1 preadipocyte differentiation reveals system-wide phosphorylation of transcriptional regulators. AB - Adipocytes (fat cells) are important endocrine and metabolic cells critical for systemic insulin sensitivity. Both adipose excess and insufficiency are associated with adverse metabolic function. Adipogenesis is the process whereby preadipocyte precursor cells differentiate into lipid-laden mature adipocytes. This process is driven by a network of transcriptional regulators (TRs). We hypothesized that protein PTMs, in particular phosphorylation, play a major role in activating and propagating signals within TR networks upon induction of adipogenesis by extracellular stimulus. We applied MS-based quantitative proteomics and phosphoproteomics to monitor the alteration of nuclear proteins during the early stages (4 h) of preadipocyte differentiation. We identified a total of 4072 proteins including 2434 phosphorylated proteins, a majority of which were assigned as regulators of gene expression. Our results demonstrate that adipogenic stimuli increase the nuclear abundance and/or the phosphorylation levels of proteins involved in gene expression, cell organization, and oxidation reduction pathways. Furthermore, proteins acting as negative modulators involved in negative regulation of gene expression, insulin stimulated glucose uptake, and cytoskeletal organization showed a decrease in their nuclear abundance and/or phosphorylation levels during the first 4 h of adipogenesis. Among 288 identified TRs, 49 were regulated within 4 h of adipogenic stimulation including several known and many novel potential adipogenic regulators. We created a kinase substrate database for 3T3-L1 preadipocytes by investigating the relationship between protein kinases and protein phosphorylation sites identified in our dataset. A majority of the putative protein kinases belong to the cyclin dependent kinase family and the mitogen-activated protein kinase family including P38 and c-Jun N-terminal kinases, suggesting that these kinases act as orchestrators of early adipogenesis. PMID- 27717187 TI - Feasibility of squeezing multiple breath washout testing into busy clinical laboratories. PMID- 27717186 TI - Anesthesia reduces discharge rates in the human pallidum without changing the discharge rate ratio between pallidal segments. AB - Classical rate models of basal ganglia circuitry associate discharge rate of the globus pallidus external and internal segments (GPe, GPi respectively) solely with dopaminergic state and predict an inverse ratio between the discharge rates of the two pallidal segments. In contrast, the effects of other rate modulators such as general anesthesia (GA) on this ratio have been ignored. To respond to this need, we recorded the neuronal activity in the GPe and GPi in awake and anesthetized human patients with dystonia (57 and 53 trajectories respectively) and in awake patients with Parkinson's disease (PD, 16 trajectories) undergoing deep brain stimulation procedures. This triad enabled us to dissociate pallidal discharge ratio from general discharge modulation. An automatic offline spike detection and isolation quality system was used to select 1560 highly isolated units for analysis. The mean discharge rate in the GPi of awake PD patients was dramatically higher than in awake dystonia patients although the firing rate in the GPe was similar. Firing rates in dystonic patients under anesthesia were lower in both nuclei. Surprisingly, in all three groups, GPe firing rates were correlated with firing rates in the ipsilateral GPi. Thus, the firing rate ratio of ipsilateral GPi/GPe pairs was similar in awake and anesthetized patients with dystonia and significantly higher in PD. We suggest that pallidal activity is modulated by at least two independent processes: dopaminergic state which changes the GPi/GPe firing rate ratio, and anesthesia which modulates firing rates in both pallidal nuclei without changing the ratio between their firing rates. PMID- 27717188 TI - Preliminary Investigation of Cardiovascular-Renal Disorders in Dogs with Chronic Mitral Valve Disease. AB - BACKGROUND: Veterinary literature lacks data about cardiovascular-renal disorders (CvRD) and cardiorenal-anemia syndrome (CRAS) in dogs. HYPOTHESIS: A direct correlation exists between ACVIM class and IRIS stage; chronic kidney disease (CKD) complicates chronic mitral valve disease (CMVD) more often than does anemia in dogs. ANIMALS: One hundred and fifty-eight client-owned dogs with CMVD. METHODS: Signalment, physical examination findings, electrocardiography, thoracic radiographs, echocardiography, and blood analysis were retrospectively evaluated to assess the prevalence of CKD and anemia in dogs with CMVD and to investigate the relationships among ACVIM class, IRIS stage, and survival. RESULTS: The prevalence of CKD and anemia in dogs with CMVD was significantly higher than in the general population of dogs. Dogs being treated for heart failure had a significantly higher prevalence of CKD than did dogs that had not received treatment. A statistically significant direct correlation was found between ACVIM class and IRIS stage. Severe heart disease, severe renal disease or both, furosemide administration, and advanced age at diagnosis of heart disease were associated with shorter survival time. Survival time of dogs affected by CvRD was statistically shorter than survival time of dogs affected by CMVD alone. CONCLUSION AND CLINICAL RELEVANCE: Chronic mitral valve disease is associated with increased prevalence of CKD and anemia in dogs. Treatment for medical management of heart failure may play a role in inducing CKD. Class of heart disease and IRIS stage were directly correlated. Cardiovascular-renal disorders decrease survival time compared to the only presence of CMVD alone, whereas anemia does not play a central role in worsening heart function. PMID- 27717191 TI - Clinicopathologic and Histopathologic Renal Abnormalities in Dogs with Coccidioidomycosis. AB - BACKGROUND: We observed evidence of protein-losing nephropathy in some dogs with coccidioidomycosis, suggestive of immune complex glomerulonephritis (ICGN). The goal of this study was to understand the prevalence of renal histopathologic lesions and proteinuria in dogs with coccidioidomycosis. HYPOTHESIS: Biochemical and histopathological evidence of glomerular lesions is present in dogs with coccidioidomycosis. ANIMALS: Hundred and fifty-six dogs with naturally occurring coccidioidomycosis. METHODS: Retrospective case series. Clinical information and results of clinicopathologic testing were retrieved from the University of California, Davis Veterinary Medical Teaching Hospital (VMTH). Microscopic sections of renal tissue procured from necropsy of dogs with coccidioidomycosis were examined to evaluate the nature and distribution of lesions. RESULTS: A total of 156 dogs with coccidioidomycosis were identified; 87 dogs had serum biochemistry and a urinalysis performed, 17 had urine protein:creatinine ratios (UPCs), and 24 had renal tissue available for histopathology. Eleven (13%) of the 87 dogs were azotemic, 55 (63%) were proteinuric (of which 14 [25%] had clinically relevant proteinuria defined as >=3+ or >=500 mg/dL), and 14 dogs had UPC >=0.5 (range, 0.5-21.5, median 4.2). Thirteen (54%) of 24 dogs had renal histopathologic lesions suggestive of ICGN. Seven of these dogs had urinalyses performed; 5 (71%) had clinically relevant proteinuria as described above. Two dogs (33%) with normal glomeruli had granulomatous nephritis, 1 of which had intralesional Coccidioides spherules. CONCLUSIONS AND CLINICAL IMPORTANCE: Coccidioidomycosis should be considered as a possible contributor to glomerular disease in dogs. Whether similar lesions occur in other mammalian hosts, including humans, warrants further investigation. PMID- 27717189 TI - Degenerative Encephalopathy in Nova Scotia Duck Tolling Retrievers Presenting with a Rapid Eye Movement Sleep Behavior Disorder. AB - BACKGROUND: Neurodegenerative diseases are a heterogeneous group of disorders characterized by loss of neurons and are commonly associated with a genetic mutation. HYPOTHESIS/OBJECTIVES: To characterize the clinical and histopathological features of a novel degenerative neurological disease affecting the brain of young adult Nova Scotia Duck Tolling Retrievers (NSDTRs). ANIMALS: Nine, young adult, related NSDTRs were evaluated for neurological dysfunction and rapid eye movement sleep behavior disorder. METHODS: Case series review. RESULTS: Clinical signs of neurological dysfunction began between 2 months and 5 years of age and were progressive in nature. They were characterized by episodes of marked movements during sleep, increased anxiety, noise phobia, and gait abnormalities. Magnetic resonance imaging documented symmetrical, progressively increasing, T2 weighted image intensity, predominantly within the caudate nuclei, consistent with necrosis secondary to gray matter degeneration. Abnormalities were not detected on clinicopathological analysis of blood and cerebrospinal fluid, infectious disease screening or urine metabolite screening in most cases. Postmortem examination of brain tissue identified symmetrical malacia of the caudate nuclei and axonal dystrophy within the brainstem and spinal cord. Genealogical analysis supports an autosomal recessive mode of inheritance. CONCLUSIONS AND CLINICAL IMPORTANCE: A degenerative encephalopathy was identified in young adult NSDTRs consistent with a hereditary disease. The prognosis is guarded due to the progressive nature of the disease, which is minimally responsive to empirical treatment. PMID- 27717190 TI - Factors Influencing the Relationship Between the Dose of Amlodipine Required for Blood Pressure Control and Change in Blood Pressure in Hypertensive Cats. AB - BACKGROUND: Hypertension is a common problem in elderly cats. In most cats, systolic blood pressure (SBP) of <160 mmHg is achieved in response to amlodipine besylate at either 0.625 or 1.25 mg q24h. The individual cat factors determining dose requirement dose have not been explored. AIMS: To determine whether individual cat factors influence the dose of amlodipine required to achieve adequate blood pressure control and to determine whether factors other than the prescribed dose of drug alter the achieved plasma amlodipine concentrations. METHODS: Fifty-nine hypertensive cats that required 0.625 mg (A) and 41 cats that required 1.25 mg (B) amlodipine to reach a target SBP of <160 mmHg were identified, and plasma amlodipine concentrations were determined. Comparisons were made between groups, and multivariable linear regression models were performed to investigate predictors of antihypertensive response. RESULTS: Cats that required a greater dose of amlodipine had significantly higher SBP at diagnosis of hypertension (A: (median [25th, 75th percentile]) 182 [175,192] mmHg; B: 207 [194,217] mmHg, P < .001), but comparable blood pressure was achieved after treatment. Plasma amlodipine concentrations were directly related to the dose of amlodipine administered. At diagnosis, cats in group B had significantly lower plasma potassium concentration (A: 4.1 [3.8,4.5]; B: 3.8 [3.6,4.2] mEq/L, P < .01). Weight did not differ between groups. The decrease in SBP was directly and independently associated with the SBP at diagnosis and the plasma amlodipine concentration. CONCLUSIONS AND CLINICAL IMPORTANCE: Cats with higher blood pressure at diagnosis might require a greater dose of amlodipine to control their blood pressure adequately. Differences in amlodipine pharmacokinetics between cats do not seem to play a role in the antihypertensive response. PMID- 27717193 TI - Barriers and facilitators to asthma self-management in adolescents: A systematic review of qualitative and quantitative studies. AB - BACKGROUND: Many adolescents have poor asthma control and impaired quality of life despite the availability of modern pharmacotherapy. Research suggests that poor adherence to treatment and limited engagement in self-management could be contributing factors. OBJECTIVE: To conduct a systematic review of the barriers and facilitators to self-management of asthma reported by adolescents using a narrative synthesis approach to integrate the findings. DESIGN: MEDLINE, EMBASE, CINAHL, and PsycINFO were searched for all types of study design. Full papers were retrieved for study abstracts that included data from participants aged 12 18 years referring to barriers or facilitators of asthma self-management behaviors. RESULTS: Sixteen studies (5 quantitative and 11 qualitative) underwent data extraction, quality appraisal, and thematic analysis. Six key themes were generated that encompassed barriers and/or facilitators to self-management of asthma in adolescents: Knowledge, Lifestyle, Beliefs and Attitudes, Relationships, Intrapersonal Characteristics, and Communication. CONCLUSIONS: There is a pressing need to prepare adolescents for self-management, using age appropriate strategies that draw on the evidence we have synthesized. Current clinical practice should focus on ensuring adolescents have the correct knowledge, beliefs, and positive attitude to self-manage their illness. This needs to be delivered in a supportive environment that facilitates two-way communication, fosters adolescents' self-efficacy to manage their disease, and considers the wider social influences that impinge on self-management.

PMID- 27717194 TI - Associations between changes in glucagon-like peptide-1 and bodyweight reduction in patients receiving acarbose or metformin treatment. AB - BACKGROUND: The present post hoc analysis investigated whether changes in endogenous glucagon-like peptide-1 (?GLP-1) levels are associated with weight loss in newly diagnosed diabetes patients. METHODS: In all, 784 subjects from the Metformin and AcaRbose in Chinese as initial Hypoglycemic treatment (MARCH) study were stratified according to ?GLP-1. Changes in clinical and physiological parameters were evaluated across ?GLP-1 subgroups (low, medium, and high) to assess correlations between ?GLP-1 and weight loss in acarbose- versus metformin treated groups. RESULTS: After 24 weeks treatment, greater ?GLP-1 was associated with significantly greater weight loss (-2 vs -1 kg in the medium/high vs low ?GLP-1 groups, respectively) and reduction in body mass index (BMI; -0.88, -0.83, and -0.69 kg/m2 in the high, medium, and low ?GLP-1 groups, respectively). In the acarbose-treated group, there was a significant association between ?GLP-1 and BMI reductions, and greater ?GLP-1 across the high, medium, and low ?GLP-1 groups was correlated with greater weight loss (-2.8, -2.1, and -1.9 kg, respectively) and reductions in fasting plasma glucose (-1.57, -1.28, and -1.02 mmol/L, respectively) at Week 24. No significant differences were found across ?GLP-1 subgroups in metformin-treated patients (P > 0.05). Multivariate linear regression analysis revealed that gender, baseline BMI, and ?GLP-1 at Week 24 were associated with weight loss. Baseline BMI and ?GLP-1 in the acarbose-treated group and baseline BMI in the metformin-treated group predicted weight loss at Week 24. CONCLUSION: Changes in GLP-1 levels are associated with weight loss in newly diagnosed Chinese diabetes patients receiving acarbose. PMID- 27717195 TI - A meta-analysis comparing clinical effects of short- or long-acting GLP-1 receptor agonists versus insulin treatment from head-to-head studies in type 2 diabetic patients. AB - AIMS: To study differences in clinical outcomes between initiating glucagon-like peptide-1 receptor agonist (GLP-1 RAs) vs insulin treatment in patients with type 2 diabetes treated with oral glucose-lowering medications (OGLM). METHODS: Prospective, randomized trials comparing GLP-1 RA and insulin treatment head-to head as add-on to OGLM were identified (PubMed). Differences from baseline values were compared for HbA1c, fasting plasma glucose, bodyweight, blood pressure, heartrate and lipoproteins. Proportions of patients reporting hypoglycaemic episodes were compared. RESULTS: Of 712 publications identified, 23 describing 19 clinical trials were included in the meta-analysis. Compared to insulin, GLP-1 RAs reduced HbA1c more effectively (Delta -.12%, P < .0001). Basal insulin was more effective in reducing fasting plasma glucose (Delta -1.8 mmol/L, P < .0001). GLP-1 RAs reduced bodyweight more effectively (Delta -3.71 kg; P < .0001). The proportion of patients experiencing hypoglycaemic episodes was 34% lower with GLP 1 RAs ( P < .0001), with a similar trend for severe hypoglycaemia. Systolic blood pressure was lower and heartrate was higher with GLP-1 RAs ( P < .0001). Triglycerides and LDL cholesterol were significantly lower with GLP-1 RAs. Long acting GLP-1 RAs were better than short-acting GLP-1 RAs in reducing HbA1c and fasting glucose, but were similar regarding bodyweight. CONCLUSIONS: Slightly better glycaemic control can be achieved by adding GLP-1 RAs to OGLM as compared to insulin treatment, with added benefits regarding bodyweight, hypoglycaemia, blood pressure and lipoproteins. These differences are in contrast to the fact that insulin is prescribed far more often than GLP-1 RAs. PMID- 27717196 TI - Changes in cellular glycosylation of leukemia cells upon treatment with acridone derivatives yield insight into drug action. AB - A new acridone derivative 2-aminoacetamido-10-(3, 5-dimethoxy)-benzyl-9(10H) acridone hydrochloride (8a) has been shown to have potent antitumor activity. In order to understand the underlying action mechanism of 8a, three compounds of the same class with structures optimized step-by-step, 9(10H)-acridone (A), 10-(3,5 dimethoxy) benzyl-9(10H)-acridone (I) and 8a, were exposed to CCRF-CEM leukemia cell to determine the N-glycosylation changes using the microfluidic HPLC-chip TOF MS platform. N-Glycans from whole cell lysates (WCL) and cell membranes (CM) were analyzed using isomer-sensitive chip-based porous graphitized carbon nano LC/MS. A total of 223 N-glycan compositions and 398 N-glycan compounds were identified. Comparison of the two analyses showed that more apparent changes were observed in the CM compared with WCL, suggesting that CM may be a more sensitive indicator of changes in glycosylation. Upon 8a exposure to CCRF-CEM cells, a significant decrease in high-mannose-type glycans was observed. Different expressions of oligosaccharyltransferase subunits appear to play a key functional role in regulating the hypoglycosylation and contribute to the action mechanism of 8a. Taken together our findings suggest that glycosylation is strongly affected by therapeutic potency and can be used as possible biomarkers for monitoring toxicity and antitumor activity of 8a. PMID- 27717197 TI - Postoperative value of serum squamous cell carcinoma antigen as a predictor of recurrence in sinonasal inverted papilloma. AB - OBJECTIVES: Sinonasal inverted papilloma (IP) has several unfavourable characteristics and therefore requires careful monitoring. The goal of this study was to identify whether serum squamous cell carcinoma antigen (SCCa) could predict IP recurrence. DESIGN: A retrospective cohort study. SETTING: Department of otolaryngology/head and neck surgery, Erasmus Medical Centre, Rotterdam, the Netherlands. PARTICIPANTS: One hundred and thirty patients with IP treated at our centre with SCCa measurements available were included. MAIN OUTCOME MEASUREMENTS: Follow-up of patients with IP since 2005, recurrence was defined as new disease within primary localisation at least 3 months after adequate surgical removal. We analysed the association between IP recurrence and serum SCCa values measured preoperatively, postoperatively and during follow-up. RESULTS: Preoperative SCCa values or values measured during follow-up were not associated with risk of recurrence. Postoperative SCCa was positively associated with the risk of recurrence (P < 0.001). Postoperative SCCa had a good discriminative ability for the identification of recurrence with an area under the curve of 80.9%. CONCLUSION: Postoperative SCCa is strongly associated with risk of recurrence. This might help the surgeon in the postoperative setting by identifying high-risk patients and planning follow-up strategy tailored to the individual patient. PMID- 27717198 TI - Young investigator challenge: Can the Ion AmpliSeq Cancer Hotspot Panel v2 be used for next-generation sequencing of thyroid FNA samples? AB - BACKGROUND: Fine-needle aspiration (FNA) cytology is accurate and cost-effective in the evaluation of thyroid nodules. Molecular techniques may contribute to risk stratification in indeterminate cases. Although next-generation sequencing (NGS) is a promising technique for the molecular testing of thyroid FNA specimens, thyroid-specific cancer gene panels are not commercially available. Conversely, the Ion AmpliSeq Cancer Hotspot Panel v2 (CHPv2), which includes the genes most frequently mutated in thyroid neoplasms, is commercially available and may represent an alternative to thyroid-specific panels. To the authors' knowledge to date, CHPv2 has performed well only on "ideal" cytological samples featuring abundant, high-quality DNA and satisfactory postsequencing metrics. The objective of the current study was to extend NGS to less-than-ideal samples, which represent a large percentage of routine clinical specimens. METHODS: A total of 37 thyroid smears were retrospectively analyzed using CHPv2, regardless of any preanalytical and postsequencing metric thresholds. Specifically, the authors evaluated the performance of CHPv2 on the BRAF, NRAS, HRAS, KRAS, and RET genes. Results were verified by pyrosequencing. RESULTS: Of the 37 thyroid FNA specimens, 34 (91.8%) were successfully processed. BRAF, NRAS, and RET somatic variants were detected in 22 of these 34 specimens (64.7%). NGS was found to have a high sensitivity (89.4%), specificity (85.7%), and accuracy (88.4%). CONCLUSIONS: CHPv2 is a valid option for the molecular evaluation of thyroid FNA specimens by NGS. It is interesting to note that this approach is accurate and effective even when applied to routine cytology samples that usually do not have optimal preanalytical and postsequencing requirements.

AB - Aggregation-induced emission (AIE) probes have shown great potential applications in fluorescent sensing of biomolecules, and the integration of AIE probe and graphene oxide (GO) attracts intense interest in developing new tools for label free and "turn-on" fluorescent biomolecular analysis. Herein, an ultrasensitive label-free and "turn-on" DNA sensing is realized by tuning the supramolecular interactions of AIE probe and GO with DNA. The investigation of supramolecular interactions of AIE probes and GO with DNA demonstrate that AIE probe with short alkyl chains substitute shows highest binding affinity with DNA strand, and GO with low oxidation degree possesses strong binding interactions to ssDNA and the highest fluorescence quenching efficiency. As a result, the optimized AIE probes and GO-based fluorescent sensor can selectively detect the target DNA sequence and exhibits the detection limitation as low as 0.17 * 10-9 m. It is believed that the research efforts will provide an efficient approach to improve the performance of DNA sensing assay and an indepth understanding of the supramolecular interactions of AIE probes and GO with DNA, and thus facilitate their extended applications in biosensors and biomedicine.

AB - In vitro culture of ovarian follicles is a promising bioengineering technique for retrieving fertilizable oocytes from preserved ovarian tissues of cancer survivors. However, current in vitro follicle culture techniques are labour intensive and of low efficiency, as only single follicle culture (SFC) has been possible to date. The present study investigated the feasibility of multifollicular cluster culture (MFCC) system using angiotensin II receptor (ATII Rc) analogues. Ovarian pre-antral follicles isolated from 2-week-old C57BL6 mice were cultured with ATII-Rc agonist or antagonist and their maturation outcomes were compared with control group. When single follicles were cultured, the ovulation and maturation rates were similar in all three groups. When three follicle clusters were cultured, up to three follicles were ovulated in the ATII Rc agonist group while none or one follicle ovulated in control or antagonist groups (p < 0.0001). Significantly higher numbers of mature oocytes were obtained in the agonist group (three-follicle 28.2 +/- 4.9 vs. SFC 11.0 +/- 1.3, per 25 cultured droplets) (p < 0.0001), and the development of each fertilized oocytes was comparable to those from SFC. It is therefore concluded that this novel MFCC system can significantly improve the efficiency of in vitro mature oocyte retrieval via ATII-Rc modulation. Copyright (c) 2016 John Wiley & Sons, Ltd.

AB - The regeneration of the anterior portion of the body after fission was studied in the holothurian Cladolabes schmeltzii using electron microscopy methods. Following fission, the posterior portion of the digestive tube, cloaca, and respiratory trees remain in the posterior fragment of the body. The regeneration comprises five stages. In the first stage, connective-tissue thickening (an anlage of the aquapharyngeal bulb) occurs on the anterior end between the torn off ends of the ambulacra. Most of the lost anterior organs developed in the second and third stages. The structures of water-vascular system and nerve ring form through dedifferentiation, proliferation, and migration of cells of the radial water-vascular canals and the radial nerve cords, correspondently. The lost digestive system portion is restored through the formation and merging of two anlagen. The digestive epithelium of the esophagus and pharynx develops from lining cells of microcavities near the central portion of the connective-tissue thickening, which probably migrate from the epidermis. The second gut anlage develops through transformation of the anterior gut remnant portion. The enterocytes partly dedifferentiate, but the epithelium retains integrity. The gut anlage grows down the mesentery and joins the regenerating aquapharyngeal bulb. In the fourth and fifth stages, all lost organs are formed and have nearly normal structure. The regeneration was concluded to occur through morphallactic rearrangements of the remaining parts of organs. Epithelial morphogenesis is the key development mechanism of the digestive, water-vascular, and nervous systems. PMID- 27717204 TI - Treatment modalities in sinonasal undifferentiated carcinoma: an analysis from the national cancer database. AB - BACKGROUND: Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive malignancy of unknown etiology with a poor overall prognosis. Its relative rarity has made it difficult to determine the impact of different treatment modalities on survival. METHODS: Retrospective study of cases in the National Cancer Data Base (NCDB). NCDB cases that were diagnosed as having SNUC between January 1, 2004, and December 31, 2013 were included in the analysis. Outcomes of patients treated with surgery followed adjuvant chemoradiotherapy were compared with definitive chemoradiotherapy. RESULTS: A 5-year survival rate of 42.2% was observed in the 460 patients in the analysis. American Joint Committee on Cancer (AJCC) clinical staging data were available for 304 patients. Of these patients, 60.2% had advanced tumors (AJCC stage 3 or 4). Surgery followed by adjuvant chemoradiotherapy was associated with better survival than definitive chemoradiotherapy (55.8% vs 42.6%, p = 0.007) in the study population. However, in late-stage tumors, there was no difference in survival between the 2 treatment groups (p = 0.22). For late-stage tumors, the time to initiation of adjuvant therapy was 49.2 +/- 5.1 days for the surgery plus adjuvant therapy group as compared with 25.9 +/- 2.6 days in the definitive chemoradiotherapy group (p < 0.0001), yet this did not appear to affect outcomes. No differences in age, gender, race, Charlson-Deyo score, facility type (academic vs nonacademic), or radiation dose were found between the 2 treatment groups (p > 0.05). Margin status played a critical role in the success of surgical resection, as no patients with positive margin status receiving adjuvant therapy survived to 5 years. CONCLUSION: Surgery may play a role in a multimodality approach to treatment of late-stage SNUC if the tumor is amenable to surgical resection and negative margins can be reliably obtained. However, in cases where there may be difficulty obtaining negative margins, or this is considered unlikely preoperatively, surgical resection does not appear to provide any additional survival benefit.

AB - Narrow bandgap (1.37-1.46 eV) polymers incorporating a head-to-head linkage containing 3-alkoxy-3'-alkyl-2,2'-bithiophene are synthesized. The head-to-head linkage enables polymers with sufficient solubility and the noncovalent sulfur oxygen interaction affords polymers with high degree of backbone planarity and film ordering. When integrated into polymer solar cells, the polymers show a promising power conversion efficiency approaching 10%. PMID- 27717206 TI - Epigenetic silencing of miR-200c in breast cancer is associated with aggressiveness and is modulated by ZEB1. AB - Loss of expression of miR-200 family members has been implicated in cellular plasticity, a phenomenon that accounts for epithelial-to-mesenchymal transition (EMT) and stem-like features of many carcinomas and is considered a major cause of tumor aggressiveness and drug resistance. Nevertheless, the mechanisms of miR 200 downregulation in breast cancer are still largely unknown. Here we show that miR-200c expression inversely correlates with miR-200c/miR-141 locus methylation in triple-negative breast tumors (TNBC). Importantly, low levels of miR-200c expression and high levels of miR-200c/miR-141 locus methylation associated with lymph node metastasis. Moreover, miR-200c/miR-141 locus methylation was significantly related to high expression of ZEB1 in two independent TNBC series. Silencing of ZEB1 in vitro reduced miR-200c/miR-141 DNA methylation and, concurrently, decreased histone H3K9 trimethylation. This chromatin modifications were paralleled by an increase in the expression of both miR-200c and E-cadherin. Similar effects were achieved by treatment with a demethylating agent. Our data suggest that gene methylation is an important element in the regulation of the miR-200c/ZEB1 axis and that chromatin remodeling of the miR-200c/miR-141 locus is affected by ZEB1 and, thus, contributes to ZEB1-induced cellular plasticity.

AB - A series of rod-like porous graphitic-carbon nitrides (short as CNs) with enhanced in-plane ordering have been fabricated through self-assembled heptazine hydrate precursors for the first time. By controlling the calcination of the preformed precursors with different temperature-rising rates, the resulted CNs (SAHEP-CNs-1) with the most ordered and least stacked graphitic planar are showing a tremendously improved hydrogen evolution rate of 420 MUmol h-1 under visible light and a remarkable apparent quantum efficiency of 8.9% at 420 nm, which is among the highest values for C3 N4 -related photocatalysts in the literature. This work discloses that enhancing in-plane ordering is one critical factor for improving the photocatalytic H2 evolution of carbon nitride, which is an effective solution to prolong the lifetime of charge carriers by accelerating the charge transport and separation within the graphitic planar. This finding would present a facial strategy for the designing of efficient organic semiconductors for photocatalysis.

PMID- 27717209 TI - Is quercetin an alternative natural crosslinking agent to genipin for long-term dermal scaffolds implantation? AB - As biocompatible matrices, porcine dermal scaffolds have limited application in tissue engineering due to rapid degradation following implantation. This study compared the physical, chemical and biomechanical changes that occurred when genipin and quercetin were used to crosslink dermal scaffolds and to determine whether quercetin could be used as an alternative to genipin. Physicochemical changes in the collagen were assessed using spectroscopic methods [X-ray diffraction analysis (XRD) and nuclear magnetic resonance (NMR) analysis]. The crosslinking reaction was evaluated by quantification of amino acids and the degree of this reaction by ninhydrin assay. Because the mechanical behaviour of the collagen matrices is highly influenced by crosslinking, the tensile strength of both sets of scaffolds was evaluated. The highest mechanical strength, stiffness, degree of crosslinking and changes in the packing features of collagen (measured by XRD) were achieved using genipin. Some of the results found in the quercetin-crosslinked scaffolds were possibly due to hydration and dehydration effects elicited by the solvents (phosphate-buffered saline or ethanol), as seen in the NMR results. In the quercetin-ethanol-crosslinked scaffolds, possible reorientation of the amino groups of the collagen molecule may have taken place. Therefore, depending on their proximity to the crosslinking reagent, different types and numbers of interactions may have occurred, inducing a higher crosslinking degree (as evidenced by the ninhydrin assay) and reduction in the free amino acids after reaction. Both crosslinking agents and solvents interfere in the physicochemical properties of collagen thereby inducing variations in the matrix structure. Quercetin-crosslinked scaffolds may have broader clinical application where a lower degree of crosslinking and stiffness is required. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27717211 TI - Offers of appointments with nurse practitioners if a requested physician is unavailable. AB - BACKGROUND AND PURPOSE: Access to primary care remains a problem for a substantial portion of the U.S. population, and is predicted to worsen due to an aging population and the increasing burden of chronic diseases. Better integration of nurse practitioners (NPs) into the primary care workforce is a possible solution. We examine offers of appointments with NPs if a requested primary care physician is unavailable. METHODS: Data are from a 2013 audit (simulated patient) study requesting appointment information from a national random sample of primary care physicians. Outcome variables include appointment offers, wait-to-appointment times, and appointment offers with alternate providers, including NPs. CONCLUSIONS: Of 922 calls to primary care physicians serving the general adult population, 378 (41%) offered appointments with the requested physician. Alternate providers were offered by 63 (7%), including nine offers with NPs (<1%). Mean wait-to-appointment for NPs (3.6 days) was statistically significantly shorter (p-values < .01) than for requested physicians (22.5 days) or non-NP alternate providers (23.9 days). IMPLICATIONS FOR PRACTICE: NPs are an important part of the primary care workforce, and new patients seeking primary care physicians may substantially reduce their wait times if an NP is offered. PMID- 27717210 TI - Patient-reported outcomes and aesthetic evaluation of root coverage procedures: a 12-month follow-up of a randomized controlled clinical trial. AB - AIM: To assess patient-reported outcome measures (PROMs), aesthetics and stability of root coverage procedures from a previous 6-month RCT after 1 year. MATERIAL & METHODS: Forty-five patients (90 recessions) had received a coronally advanced flap (CAF = control) only or a xenogeneic collagen matrix in addition (CAF + CMX = test). Visual analogue scales (VAS) and questionnaires were used for PROMs and the root coverage aesthetic score (RES) for professional aesthetic evaluations. RESULTS: VAS scores (patient satisfaction) amounted to 8.58 +/- 1.86 (test) versus 8.38 +/- 2.46 (control). Six patients preferred CAF + CMX concerning surgical procedure and aesthetics, six preferred CAF and 29 were equally satisfied. RES was 7.85 +/- 2.42 for the test group versus 7.34 +/- 2.90 for the controls. Root coverage (RC) was 76.28% for test and 75.05% for control defects. The mean increase in keratinized tissue width was higher in test (from 1.97 to 3.02 mm) than in controls (from 2.00 to 2.64 mm) (p = 0.0413). Likewise, test sites showed more gain in gingival thickness (0.52 mm) than control sites (0.27 mm) (p = 0.0023). Compared to 6 months, clinical outcomes were stable. CONCLUSIONS: Results for PROMs, RES and RC did not significantly differ between treatment groups. Thickness and width of keratinized tissue were enhanced following CAF + CMX compared to CAF alone.

AB - Side-chain fluorination of polymers is demonstrated as a highly effective strategy to improve the efficiency of all-polymer solar cells from 2.93% (nonfluorinated P1) to 7.13% (fluorinated P2). This significant enhancement is achieved by synergistic improvements in open-circuit voltage, charge generation, and charge transport, as fluorination of the donor polymer optimizes the band alignment and the film morphology.

These PDI-helicene homologs exhibit very different structural and electronic properties, despite differing by only a single ring in the link between the PDI units. The shorter inter-PDI link brings the two PDI subunits closer together, and this results in the collision of their respective pi-electron clouds. This collision facilitates intramolecular through space electronic delocalization when the PDI-helicene is reduced. PMID- 27717215 TI - DNA barcodes of the native ray-finned fishes in Taiwan. AB - Species identification based on the DNA sequence of a fragment of the cytochrome c oxidase subunit I gene in the mitochondrial genome, DNA barcoding, is widely applied to assist in sustainable exploitation of fish resources and the protection of fish biodiversity. The aim of this study was to establish a reliable barcoding reference database of the native ray-finned fishes in Taiwan. A total of 2993 individuals, belonging to 1245 species within 637 genera, 184 families and 29 orders of ray-finned fishes and representing approximately 40% of the recorded ray-finned fishes in Taiwan, were PCR amplified at the barcode region and bidirectionally sequenced. The mean length of the 2993 barcodes is 549 bp. Mean congeneric K2P distance (15.24%) is approximately 10-fold higher than the mean conspecific one (1.51%), but approximately 1.4-fold less than the mean genetic distance between families (20.80%). The Barcode Index Number (BIN) discordance report shows that 2993 specimens represent 1275 BINs and, among them, 86 BINs are singletons, 570 BINs are taxonomically concordant, and the other 619 BINs are taxonomically discordant. Barcode gap analysis also revealed that more than 90% of the collected fishes in this study can be discriminated by DNA barcoding. Overall, the barcoding reference database established by this study reveals the need for taxonomic revisions and voucher specimen rechecks, in addition to assisting in the management of Taiwan's fish resources and diversity. PMID- 27717213 TI - The brain-derived neurotrophic factor Val66Met polymorphism affects encoding of object locations during active navigation. AB - The brain-derived neurotrophic factor (BDNF) was shown to be involved in spatial memory and spatial strategy preference. A naturally occurring single nucleotide polymorphism of the BDNF gene (Val66Met) affects activity-dependent secretion of BDNF. The current event-related fMRI study on preselected groups of 'Met' carriers and homozygotes of the 'Val' allele investigated the role of this polymorphism on encoding and retrieval in a virtual navigation task in 37 healthy volunteers. In each trial, participants navigated toward a target object. During encoding, three positional cues (columns) with directional cues (shadows) were available. During retrieval, the invisible target had to be replaced while either two objects without shadows (objects trial) or one object with a shadow (shadow trial) were available. The experiment consisted of blocks, informing participants of which trial type would be most likely to occur during retrieval. We observed no differences between genetic groups in task performance or time to complete the navigation tasks. The imaging results show that Met carriers compared to Val homozygotes activate the left hippocampus more during successful object location memory encoding. The observed effects were independent of non-significant performance differences or volumetric differences in the hippocampus. These results indicate that variations of the BDNF gene affect memory encoding during spatial navigation, suggesting that lower levels of BDNF in the hippocampus results in less efficient spatial memory processing. PMID- 27717217 TI - Histopathological features of a patient with Charcot-Marie-Tooth disease type 2U/AD-CMTax-MARS. AB - Charcot-Marie-Tooth (CMT) disease is a complex of peripheral nervous system disorders. CMT type 2U (CMT2U) is an autosomal dominant (AD) disease caused by mutations in the MARS gene encoding methionyl-tRNA synthetase; this disease has thus been newly called AD-CMTax-MARS. A few families with mutations in the MARS gene have been reported, without detailed histopathological findings. We describe a 70-year-old woman who had bilateral dysesthesia of the soles since the age of 66 years. Sural nerve biopsy showed a decrease in the density of large myelinated nerve fibers. Increased clusters of regenerating myelinated nerve fibers were noted. Electron microscopic analyses revealed degeneration of unmyelinated nerves. There was no vasculitis or inflammatory cell infiltration. Genetic analysis identified a heterozygous p.P800T mutation, a reported mutation in the MARS gene. We report the detailed histopathological findings in a patient with CMT2U/AD-CMTax-MARS. The findings are similar to those found in CMT2D caused by mutations in the GARS gene, encoding glycyl-tRNA synthetase. PMID- 27717216 TI - Simulation, phantom validation, and clinical evaluation of fast pH-weighted molecular imaging using amine chemical exchange saturation transfer echo planar imaging (CEST-EPI) in glioma at 3 T. AB - Acidity within the extracellular milieu is a hallmark of cancer. There is a current need for fast, high spatial resolution pH imaging techniques for clinical evaluation of cancers, including gliomas. Chemical exchange saturation transfer (CEST) MRI targeting fast-exchanging amine protons can be used to obtain high resolution pH-weighted images, but conventional CEST acquisition strategies are slow. There is also a need for more accurate MR simulations to better understand the effects of amine CEST pulse sequence parameters on pH-weighted image contrast. In the current study we present a simulation of amine CEST contrast specific for a newly developed CEST echoplanar imaging (EPI) pulse sequence. The accuracy of the simulations was validated by comparing the exchange rates and Z spectrum under a variety of conditions using physical phantoms of glutamine with different pH values. The effects of saturation pulse shapes, pulse durations, pulse train lengths, repetition times, and relaxation rates of bulk water and exchangeable amine protons on the CEST signal were explored for normal-appearing white matter (NAWM), glioma, and cerebrospinal fluid. Last, 18 patients with WHO II-IV gliomas were evaluated. Results showed that the Z-spectrum was highly dependent on saturation pulse shape, repetition time, saturation amplitude, magnetic field strength, and T2 within bulk water; however, the Z-spectrum was only minimally influenced by saturation pulse duration and the specific relaxation rates of amine protons. Results suggest that a Gaussian saturation pulse train consisting of 3 * 100 ms pulses using the minimum allowable repetition time is optimal for achieving over 90% available contrast across all tissues. Results also demonstrate that high saturation pulse amplitude and scanner field strength (>3 T) are necessary for adequate endogenous pH-weighted amine CEST contrast. pH-weighted amine CEST contrast increased with increasing tumor grade, with glioblastoma showing significantly higher contrast compared with WHO II or III gliomas. PMID- 27717220 TI - Nurse practitioners and intent to retire. AB - BACKGROUND AND PURPOSE: Demand for primary care services is rising. Nurse practitioners (NPs) serve vital roles in meeting primary care demands. Workforce planning requires understanding NP retirement intentions. This study examines factors that relate to NPs, aged 55 years and older, and their intent to retire within 5 years. METHODS: We used the 2012 National Sample Survey of Nurse Practitioners to examine the relationship between NP demographic characteristics (gender, race/ethnicity, marital status, nursing degree), work environment characteristics (part-time vs. full-time status, primary or specialty care, earnings, job satisfaction), and intent to retire. Descriptive, bivariate, and multivariate analyses were conducted. A total of 3171 working NPs, 55 years of age and older, were included. CONCLUSIONS: Fifty-nine percent of NPs 60 years and older and 15% of NPs 55-59 intend to retire in the next 5 years. Working part time and having less than a master's degree were associated with intent to retire. Being "very satisfied" with one's job was related to lower odds of intent to retire versus being "satisfied." Being "dissatisfied" with one's job and working in primary care were related to intending to retire for the NPs 55-59. IMPLICATIONS FOR PRACTICE: Given the relationship between higher job satisfaction and lower intent to retire, efforts to increase NPs' job satisfaction may result in less early retirement.

AB - Allergic bronchopulmonary aspergillosis (ABPA) affects up to 15% of patients with cystic fibrosis (CF). Corticosteroids are used as first-line therapy, but relapse and adverse effects commonly occur. Case reports have suggested the efficacy of the anti-IgE recombinant humanized monoclonal antibody omalizumab. A retrospective multicenter observational French study retrieved 32 CF patients (11 children and 21 adults) who have received omalizumab for more than 3 months in the context of ABPA. Clinical characteristics, concomitant medications (inhaled and oral corticosteroids, antifungal drugs), lung function, body mass index (BMI), and serum IgE were compared at the start and during the first year of omalizumab therapy. Omalizumab-related adverse effects and costs were also evaluated. No significant difference with omalizumab could be demonstrated with regard to lung function, BMI, or the number of patients receiving oral corticosteroids. At the time of initiation of omalizumab, 56% of patients were receiving oral corticosteroids. Five patients were able to discontinue corticosteroids during follow-up and nine patients were able to reduce their daily dose. A total of 78% of the patients had received antifungal therapy at the time of the initiation of omalizumab. Treatment tolerance was good (12.5% of patients experienced side effects). The median cost of omalizumab treatment was ?3,620 per patient per month. Omalizumab may represent a steroid-sparing therapy in CF patients with ABPA. A randomized-controlled trial is urgently required to provide higher level of evidence regarding the efficacy and cost-effectiveness of omalizumab in CF patients with ABPA.

PMID- 27717222 TI - Effect of GLP-1 receptor agonist treatment on body weight in obese antipsychotic treated patients with schizophrenia: a randomized, placebo-controlled trial. AB - AIMS: Schizophrenia is associated with cardiovascular co-morbidity and a reduced life-expectancy of up to 20 years. Antipsychotics are dopamine D2 receptor antagonists and are the standard of medical care in schizophrenia, but the drugs are associated with severe metabolic side effects such as obesity and diabetes. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are registered for treatment of both obesity and type 2 diabetes. We investigated metabolic effects of the GLP 1RA, exenatide once-weekly, in non-diabetic, antipsychotic-treated, obese patients with schizophrenia. MATERIAL AND METHODS: Antipsychotic-treated, obese, non-diabetic, schizophrenia spectrum patients were randomized to double-blinded adjunctive treatment with once-weekly subcutaneous exenatide (n = 23) or placebo (n = 22) injections for 3 months. The primary outcome was loss of body weight after treatment and repeated measures analysis of variance was used as statistical analysis. RESULTS: Between March 2013 and June 2015, 40 patients completed the trial. At baseline, mean body weight was 118.3 +/- 16.0 kg in the exenatide group and 111.7 +/- 18.0 kg in the placebo group, with no group differences ( P = .23). The exenatide and placebo groups experienced significant ( P = .004), however similar ( P = .98), weight losses of 2.24 +/- 3.3 and 2.23 +/- 4.4 kg, respectively, after 3 months of treatment. CONCLUSIONS: Treatment with exenatide once-weekly did not promote weight loss in obese, antipsychotic treated patients with schizophrenia compared to placebo. Our results could suggest that the body weight-lowering effect of GLP-1RAs involves dopaminergic signaling, but blockade of other receptor systems may also play a role. Nevertheless, anti-obesity regimens effective in the general population may not be readily implemented in antipsychotic-treated patients with schizophrenia.

PMID- 27717228 TI - The consequences of facultative sex in a prey adapting to predation. AB - A species reproductive mode, along with its associated costs and benefits, can play a significant role in its evolution and survival. Facultative sexuality, being able to reproduce both sexually and asexually, has been deemed evolutionary favourable as the benefits of either mode may be fully realized. In fact, many studies have focused on identifying the benefits of sex and/or the forces selecting for increased rates of sex using facultative sexual species. The costs of either mode, however, can also have a profound impact on a population's evolutionary trajectory. Here, we used experimental evolution and fitness assays to investigate the consequences of facultative sexuality in prey adapting to predation. Specifically, we compared the adaptive response of algal prey populations exposed to constant rotifer predation and which had alternating cycles of asexual and sexual reproduction where sexual episodes were either facultative (sexual and asexual progeny simultaneously propagated) or obligate (only sexual progeny propagated). We found that prey populations with facultative sexual episodes reached a lower final relative fitness and suffered a greater trade-off in traits under selection, that is defence and competitive ability, as compared to prey populations with obligate sexual episodes. Our results suggest that costs associated with sexual reproduction (germination time) and asexual reproduction (selection interference) were amplified in the facultative sexual prey populations, leading to a reduction in the net advantage of sexuality. Additionally, we found evidence that the cost of sex was reduced in the obligate sexual prey populations because increased selection for sex was observed via the spontaneous production of sexual cells. These results show that certain costs associated with facultative sexuality can affect an organism's evolutionary trajectory. PMID- 27717227 TI - Continuous Production of Discrete Plasmid DNA-Polycation Nanoparticles Using Flash Nanocomplexation. AB - Despite successful demonstration of linear polyethyleneimine (lPEI) as an effective carrier for a wide range of gene medicine, including DNA plasmids, small interfering RNAs, mRNAs, etc., and continuous improvement of the physical properties and biological performance of the polyelectrolyte complex nanoparticles prepared from lPEI and nucleic acids, there still exist major challenges to produce these nanocomplexes in a scalable manner, particularly for lPEI/DNA nanoparticles. This has significantly hindered the progress toward clinical translation of these nanoparticle-based gene medicine. Here the authors report a flash nanocomplexation (FNC) method that achieves continuous production of lPEI/plasmid DNA nanoparticles with narrow size distribution using a confined impinging jet device. The method involves the complex coacervation of negatively charged DNA plasmid and positive charged lPEI under rapid, highly dynamic, and homogeneous mixing conditions, producing polyelectrolyte complex nanoparticles with narrow distribution of particle size and shape. The average number of plasmid DNA packaged per nanoparticles and its distribution are similar between the FNC method and the small-scale batch mixing method. In addition, the nanoparticles prepared by these two methods exhibit similar cell transfection efficiency. These results confirm that FNC is an effective and scalable method that can produce well-controlled lPEI/plasmid DNA nanoparticles.

PMID- 27717229 TI - Long-term Use of Z-Hypnotics and Co-medication with Benzodiazepines and Opioids. AB - Benzodiazepine-like drugs (z-hypnotics) are the most commonly used drugs for treatment of insomnia in Norway. Z-hypnotics are recommended for short-term treatment not exceeding 4 weeks. We aimed to study the use of z-hypnotics in the adult population in Norway with focus on recurrent use in new users, treatment intensity and co-medication with benzodiazepines and opioids in long-term users. Data were obtained from the Norwegian Prescription Database. New users in 2009 were followed through 2013. Recurrent z-hypnotic use was defined as new fillings at least once in each of the four 365-day follow-up periods. Age groups of 18-39, 40-64 and 65+ years were analysed separately for men and women. In 2013, 354,571 (8.9%) of the population filled at least one prescription of z-hypnotics and the prevalence was relatively stable over time. Among the 92,911 new users of z hypnotics in 2009, 13,996 (16.8%) received z-hypnotics all four 365-day periods of follow-up. In these long-term recurrent users, the treatment intensity was high already the second year, with mean annual amounts of 199 and 169 DDDs per patient in men and women, respectively. The interquartile differences were greatest in the youngest age group. 27.9% of the long-term recurrent users of z hypnotics used benzodiazepines the fourth year and 33.9% used opioids. The proportions with co-medication increased with level of z-hypnotic treatment intensity. Overall, many z-hypnotic users had medicines dispensed for longer periods than recommended, and co-medications with drugs that may reinforce the central depressing and intoxicating effects were common.

AB - Using small interfering RNA (siRNA) to regulate gene expression is an emerging strategy for stem cell manipulation to improve stem cell therapy. However, conventional methods of siRNA delivery into stem cells based on solution-mediated transfection are limited due to low transfection efficiency and insufficient duration of cell-siRNA contact during lengthy culturing protocols. To overcome these limitations, a bio-inspired polymer-mediated reverse transfection system is developed consisting of implantable poly(lactic-co-glycolic acid) (PLGA) scaffolds functionalized with siRNA-lipidoid nanoparticle (sLNP) complexes via polydopamine (pDA) coating. Immobilized sLNP complexes are stably maintained without any loss of siRNA on the pDA-coated scaffolds for 2 weeks, likely due to the formation of strong covalent bonds between amine groups of sLNP and catechol group of pDA. siRNA reverse transfection with the pDA-sLNP-PLGA system does not exhibit cytotoxicity and induces efficient silencing of an osteogenesis inhibitor gene in human adipose-derived stem cells (hADSCs), resulting in enhanced osteogenic differentiation of hADSCs. Finally, hADSCs osteogenically committed on the pDA-sLNP-PLGA scaffolds enhanced bone formation in a mouse model of critical sized bone defect. Therefore, the bio-inspired reverse transfection system can provide an all-in-one platform for genetic modification, differentiation, and transplantation of stem cells, simultaneously enabling both stem cell manipulation and tissue engineering.

It has been reported earlier that nearly half of the patients who have undergone laryngectomy after larynx cancer diagnosis still continue to consume alcohol after the operation. The aim of this study was to compare the mood and character features of patients who do or do not consume alcohol during the postoperative period and thus to be able to predict the patients who will continue their alcohol use at the postoperative period. MATERIALS AND METHODS: The patients who have undergone partial or total laryngectomy operation were included in this study. To avoid early period treatment stress, it was required that the patients have completed their 6 months of postoperative period. The interviews made with the patients included filling out of the sociodemographic data form, TCI (temperament and character inventory), BDI (Beck depression inventory), BAI (Beck anxiety inventory), AUDIT (alcohol use disorders identification test) and CAGE (cut-down, annoyed, guilty, eye-opener) inquiry forms. RESULTS: 80 patients who admitted alcohol consumption at the time of larynx cancer diagnosis were divided in to two groups and, 40% (n = 32) of this patients continued alcohol consumption after laryngectomy (Group 1) and 60% (n = 48) cut down on their alcohol use (Group 2). A statistically significant difference was observed between Group 1 and Group 2 at AUDIT and CAGE score averages (P < 0.001, P < 0.001, respectively). When TCI data were compared between Group 1 and Group 2, patients who continued their alcohol use at the postoperative period had significantly higher novelty seeking scores compared to others (P = 0.03). CONCLUSION: Our data suggest that it may be possible in the preoperative period to predict the patients who will continue their alcohol use in the postoperative period and take precautions. PMID- 27717235 TI - Exogenous lipoid pneumonia induced by nasal decongestant. AB - INTRODUCTION: Lipoid pneumonia is a clinical condition that may be initially asymptomatic or confused with an infectious or malignant lung disease. OBJECTIVES: We report four cases of this pathological condition. METHODS: The first case concerned an 85-year old woman with bilateral confluent pulmonary opacities, ground-glass type. Diagnosis was based on the cytology of the bronchoalveolar lavage (BAL) fluid followed by its ultrastructural examination. The second case was a 47-year-old man with an isolated pulmonary nodule, which was surgically removed; the diagnosis of lipoid pneumonia was formulated on the basis of the histological and electron microscopy examination. The third case concerned a 73-year-old woman, with bilateral hypodense areas at the bases of the lungs where FDG PET/CT scan showed an increased uptake. Diagnosis was formulated by BAL cytology and electron microscopy examination. The fourth case was a 69 year-old man, who performed a virtual colonoscopy for diverticulosis putting in evidence a round mass (3 cm in diameter) with two small peripheral nodules, located in the pulmonary left lower lobe. The histopathological examination of transthoracic biopsy confirmed a lipoid pneumonia. RESULTS AND CONCLUSION: In all four cases, it was put in evidence a prolonged use of a nasal decongestant containing mineral oils. In literature, the most cases described are characterized by a subclinical evolution and were presented as ground glass opacities which evolve, in the later phases, in an interstitial involvement or in a peripheral mass, simulating a lung tumour. PMID- 27717237 TI - Identification and validation of novel small proteins in Pseudomonas putida. AB - Small proteins of 50 amino acids or less have been understudied due to difficulties that impede their annotation and detection. In order to obtain information on small open reading frames (sORFs) in Pseudomonas putida, bioinformatic and proteomic approaches were used to identify putative sORFs in the well-characterized strain KT2440. A plasmid-based system was established for sORF validation, enabling expression of C-terminal sequential peptide affinity tagged variants and their detection via protein immunoblotting. Out of 22 tested putative sORFs, the expression of 14 sORFs was confirmed, where all except one are novel. All of the validated sORFs except one are located adjacent to annotated genes on the same strand and three are in close proximity to genes with known functions. These include an ABC transporter operon and the two transcriptional regulators Fis and CysB involved in biofilm formation and cysteine biosynthesis respectively. The work sheds light on the P. putida small proteome and small protein identification, a necessary first step towards gaining insights into their functions and possible evolutionary implications.

AB - AIMS: Low serum 25-hydroxyvitamin-D (25(OH)D) concentrations are associated with insulin resistance, beta-cell dysfunction and type 2 diabetes. We conducted a 24 week double-blind, randomized, placebo-controlled trial to examine the effect of 28 000 IU of vitamin D3 once weekly on plasma glucose after a 2 hour-75 g oral glucose tolerance test (2hrPC glucose), insulin sensitivity and beta-cell function. STUDY DESIGN AND METHODS: A total of 71 participants with serum 25(OH)D <=65 nmol/L, impaired fasting glucose and elevated glycated hemoglobin were randomly assigned to receive 28 000 IU of vitamin D3 (VitD; n = 35) or placebo (n = 36) in cheese once weekly for 24 weeks. The primary outcome was the change in 2hPC glucose. Secondary outcomes were fasting glucose, fasting and postprandial insulin, indices of insulin sensitivity and beta-cell function, glycated hemoglobin and lipid profile. Participants underwent an oral glucose tolerance test to determine 2hPC glucose. RESULTS: Mean baseline serum 25(OH)D was 48.1 and 47.6 nmol/L in the VitD and placebo groups, respectively. Serum 25(OH)D significantly increased to 98.7 nmol/L (51 nmol/L increase; P < .0001) in the VitD group. No significant differences in fasting ( P = .42) or 2hPC glucose ( P = .55) or other indices of glucose metabolism, including beta-cell function and insulin sensitivity, were observed between groups. A subgroup analysis of individuals with 25(OH)D < 50 nmol/L and prediabetes did not change these results. The VitD group exhibited a significant reduction in LDL cholesterol ( 0.27 vs 0.01 mmol/L, P = .03). CONCLUSION: Weekly doses of vitamin D3 in individuals with suboptimal vitamin D levels who were at risk for type 2 diabetes did not improve oral glucose tolerance or markers of glycaemic status. PMID- 27717238 TI - Multifunctional WS2 @Poly(ethylene imine) Nanoplatforms for Imaging Guided Gene Photothermal Synergistic Therapy of Cancer. AB - The combination of photothermal therapy (PTT) with gene therapy (GT) to improve PTT efficiency and thus eliminate cancer cells under mild hyperthermia is highly needed. Herein, multifunctional WS2 @poly(ethylene imine) (WS2 @PEI) nanoplatform has been designed and constructed for gene-photothermal synergistic therapy of tumors at mild condition. After a surface modification of WS2 with a positively charged PEI, the as-prepared WS2 @PEI nanoplatform can not only act as an efficient survivin-siRNA carrier for GT but also exhibit remarkable near-infrared (NIR) photothermal effects for PTT. On the one hand, the photothermal effects induced by WS2 @PEI upon NIR irradiation can enhance the cellular uptake owing to the increase of the cell membrane permeability, which leads to the remarkable enhancement of silencing efficiency of survivin. On the other hand, the silencing of survivin can increase the apoptosis as well as reduce the heat resistance of cancer cells by downregulating the heat shock protein 70 expressions, which greatly enhance the sensitivity of cancer cells to PTT. As a result, compared to PTT or GT treatment alone, WS2 @PEI mediated synergistic GT/PTT therapy remarkably enhances in vitro cancer cell damage and in vivo tumor elimination.

AB - Benzaldehyde-terminated telechelic four-armed polyethylene glycol (PEG-BA) is synthesized and cross-linked with carboxymethyl chitosan (CMC) to form dynamic hydrogels with strong mechanical performance. The gelation temperature and time, mechanical performance, and self-healing behaviors are systematically investigated. The hydrogels have good storage modulus up to 3162.06 +/- 21.06 Pa, comparable to conventional bulk hydrogels. The separated alternate hydrogel lines connect together to become an integrated hydrogel film after 5 min at room temperature without any external intervention. This is due to the dynamic equilibrium between the Schiff base linkages and the aldehyde groups of PEG-BA and amine groups on CMC backbone. The hydrogel shows excellent cytocompatibility and the cell viability is as high as 90.7 +/- 6.8% after 2 d 3D encapsulation in the hydrogel. In vivo tests indicate that the hydrogels can effectively stop bleeding when the hydrogel is directly injected into a rabbit liver incision. The total blood loss is reduced from 0.65 +/- 0.10 g to 0.29 +/- 0.11 g, and the hemostasis time is decreased from 167 +/- 21 s to 120 +/- 10 s, when compared to a gauze treatment with physical compression. These self-healing hydrogels have potential to be used as a novel hemostatic material. PMID- 27717240 TI - Attitudes toward evidence-based clinical decision support tools to reduce exposure to ionizing radiation: The Canadian CT Head Rule. AB - BACKGROUND AND PURPOSE: A large degree of variation in clinical practice exists among clinicians evaluating and treating individuals with minor head injuries. Noncontrast head computerized tomography (CT) scans are commonly used to assess for intracranial damage in patients presenting with head injury. This practice is not supported by the evidence and poses harm to patients by increasing exposure to ionizing radiation. This form of radiation exposure increases the risk of developing cancers over the course of the individual's life, and further strains the limited resources of the healthcare system. PROJECT SUMMARY: This article describes the findings of an evidence-based practice project assessing the attitudes of clinicians toward an evidence-based clinical decision support tool (Canadian CT Head Rule [CCHR]). The CCHR has 100% sensitivity in detecting all clinically important brain injuries and any injury requiring neurosurgical intervention. This clinical decision support (CDS) tool is designed to help guide clinicians in the prudent use of head CT scans in people ages 16-64 that have sustained minor head injuries. The Evidence-Based Attitude Scale was also used to identify which domains were most influential on willingness to adopt into clinical practice. CONCLUSIONS: The results revealed an 84% increase in clinician knowledge of the use of the CCHR. A majority (83%) of participants reported moderate likelihood of adoption of the CDS tool into clinical practice if they found the tool appealing, and it was required by a governing authority. The use of CDS tools can help healthcare providers mitigate the risk associated with caring for complex patients. CDS tools provide a systematic method to evaluate patients with minor head injuries while assuring consistency of care and quality outcomes. This practice of assuring consistency and good patient outcomes is foundational to the concept of standard of care, which serves to improve clinical practice.

AB - Thin film dewetting can be efficiently exploited for the implementation of functionalized surfaces over very large scales. Although the formation of sub micrometer sized crystals via solid-state dewetting represents a viable method for the fabrication of quantum dots and optical meta-surfaces, there are several limitations related to the intrinsic features of dewetting in a crystalline medium. Disordered spatial organization, size, and shape fluctuations are relevant issues not properly addressed so far. This study reports on the deterministic nucleation and precise positioning of Si- and SiGe-based nanocrystals by templated solid-state dewetting of thin silicon films. The dewetting dynamics is guided by pattern size and shape taking full control over number, size, shape, and relative position of the particles (islands dimensions and relative distances are in the hundreds nm range and fluctuate ~11% for the volumes and ~5% for the positioning).

One of them had a novel mutation c.870-1G>C in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. There have been 38 Chinese CF patients reported in literature from 1974 until the present (2016), 25 different mutations were identified. Only one of these mutations (R553X) is in the Caucasian CF screening panel. The mutations identified in Chinese CF patients are very different from the common Caucasian gene mutations. The CFTR gene mutation spectrum for the Chinese population requires further investigation. Pediatr Pulmonol. 2017;52:E11-E14. (c) 2016 The Authors.

PMID- 27717241 TI - Characterization of a caveolin-1 mutation associated with both pulmonary arterial hypertension and congenital generalized lipodystrophy. AB - Congenital generalized lipodystrophy (CGL) and pulmonary arterial hypertension (PAH) have recently been associated with mutations in the caveolin-1 ( CAV1 ) gene, which encodes the primary structural protein of caveolae. However, little is currently known about how these CAV1 mutations impact caveolae formation or contribute to the development of disease. Here, we identify a heterozygous F160X CAV1 mutation predicted to generate a C-terminally truncated mutant protein in a patient with both PAH and CGL using whole exome sequencing, and characterize the properties of CAV1 , caveolae-associated proteins and caveolae in skin fibroblasts isolated from the patient. We show that morphologically defined caveolae are present in patient fibroblasts and that they function in mechanoprotection. However, they exhibited several notable defects, including enhanced accessibility of the C-terminus of wild-type CAV1 in caveolae, reduced colocalization of cavin-1 with CAV1 and decreased stability of both 8S and 70S oligomeric CAV1 complexes that are necessary for caveolae formation. These results were verified independently in reconstituted CAV1 -/- mouse embryonic fibroblasts. These findings identify defects in caveolae that may serve as contributing factors to the development of PAH and CGL and broaden our knowledge of CAV1 mutations associated with human disease.

AB - Abnormal telomere lengths have been linked to cancer and other hematologic disorders. Determination of mean telomere content (MTC) is traditionally performed by Southern blotting and densitometry, giving a mean telomere restriction fragment (TRF) value for the total cell population studied. Here, we compared a quantitative Polymerase Chain Reaction approach (qPCR) and a flow cytometric approach, fluorescence in situ hybridization (Flow-FISH), to evaluate telomere content distribution in total patient peripheral blood mononuclear cells or specific cell populations. Flow-FISH is based on in situ hybridization using a fluorescein-labeled peptide nucleic acid (PNA) (CCCTAA)3 probe and DNA staining with propidium iodide. We showed that both qPCR and Flow-FISH provide a robust measurement, with Flow-FISH measuring a relative content longer than qPCR at a single cell approach and that TRF2 fluorescence intensity did not correlate with MTC. Both methods showed comparable telomere content reduction with age, and the rate of relative telomere loss was similar. Published 2016 Wiley Periodicals Inc.

PMID- 27717245 TI - tipdatingbeast: an r package to assist the implementation of phylogenetic tip dating tests using beast. AB - Molecular tip dating of phylogenetic trees is a growing discipline that uses DNA sequences sampled at different points in time to coestimate the timing of evolutionary events with rates of molecular evolution. In this context, beast, a program for Bayesian analysis of molecular sequences, is the most widely used phylogenetic tool. Here, we introduce tipdatingbeast, an r package built to assist the implementation of various phylogenetic tip-dating tests using beast. tipdatingbeast currently contains two main functions. The first one allows preparing date-randomization analyses, which assess the temporal signal of a data set. The second function allows performing leave-one-out analyses, which test for the consistency between independent calibration sequences and allow pinpointing those leading to potential bias. We apply those functions to an empirical data set and supply practical guidance for results interpretation. PMID- 27717246 TI - Exercise-induced inspiratory symptoms in school children. AB - BACKGROUND AND AIMS: Exercise-induced inspiratory symptoms (EIIS) have multiple causes, one of which is exercise-induced laryngeal obstruction (EILO). There is limited knowledge regarding EIIS in children, both in primary care practices and in pediatric asthma clinics. The aim of this study was to describe the feasibility of a diagnostic methodology and its results in a cohort of children with EIIS referred to our tertiary pediatric pulmonary center. METHODS: This study analyzed consecutively collected data in children from East Denmark and Greater Copenhagen referred during a 31/2 years period. The continuous laryngoscopy exercise (CLE) test directly visualizes the larynx using a flexible laryngoscope during a maximal exercise test. A post-test questionnaire evaluated the subjective impact of the examination. RESULTS: The study included 60 children (37 girls/23 boys) with a mean age of 14 years (range 9-18). The feasibility of the CLE test was 98%; 18 children (35%) had EILO, while 33 children (61%) showed no abnormalities. Other laryngeal abnormalities were observed in three children before the exercise test. Asthma medication was successfully discontinued in 13 (72%) children with EILO. A significantly greater proportion of children shown to have EILO in the CLE test reported coping better with their EIIS than children with negative test (85% vs. 45%; P = 0.03). CONCLUSIONS: Continuous laryngoscopy during exercise is feasible and useful for identifying children with EILO. A correct diagnosis of EILO can help relieve patient anxiety, improve their coping with symptoms, and prevent unnecessary long-term and potentially harmful asthma treatments involving high-dose inhaled steroids.

PMID- 27717247 TI - Comparative transcriptomics reveal host-specific nucleotide variation in entomophthoralean fungi. AB - Obligate parasites are under strong selection to increase exploitation of their host to survive while evading detection by host immune defences. This has often led to elaborate pathogen adaptations and extreme host specificity. Specialization on one host, however, often incurs a trade-off influencing the capacity to infect alternate hosts. Here, we investigate host adaptation in two morphologically indistinguishable and closely related obligate specialist insect pathogenic fungi from the phylum Entomophthoromycota, Entomophthora muscae sensu stricto and E. muscae sensu lato, pathogens of houseflies (Musca domestica) and cabbage flies (Delia radicum), respectively. We compared single nucleotide polymorphisms within and between these two E. muscae species using 12 RNA-seq transcriptomes from five biological samples. All five isolates contained intra isolate polymorphisms that segregate in 50:50 ratios, indicative of genetic duplication events or functional diploidy. Comparative analysis of dN/dS ratios between the multinucleate E. muscae s.str. and E. muscae s.l. revealed molecular signatures of positive selection in transcripts related to utilization of host lipids and the potential secretion of toxins that interfere with the host immune response. Phylogenetic comparison with the nonobligate generalist insect pathogenic fungus Conidiobolus coronatus revealed a gene-family expansion of trehalase enzymes in E. muscae. The main sugar in insect haemolymph is trehalose, and efficient sugar utilization was probably important for the evolutionary transition to obligate insect pathogenicity in E. muscae. These results support the hypothesis that genetically based host specialization in specialist pathogens evolves in response to the challenge of using resources and dealing with the immune system of different hosts.

AB - We report the current best estimate of the effects of cognitive behavior therapy (CBT) in the treatment of major depression (MDD), generalized anxiety disorder (GAD), panic disorder (PAD) and social anxiety disorder (SAD), taking into account publication bias, the quality of trials, and the influence of waiting list control groups on the outcomes. In our meta-analyses, we included randomized trials comparing CBT with a control condition (waiting list, care-as-usual or pill placebo) in the acute treatment of MDD, GAD, PAD or SAD, diagnosed on the basis of a structured interview. We found that the overall effects in the 144 included trials (184 comparisons) for all four disorders were large, ranging from g=0.75 for MDD to g=0.80 for GAD, g=0.81 for PAD, and g=0.88 for SAD. Publication bias mostly affected the outcomes of CBT in GAD (adjusted g=0.59) and MDD (adjusted g=0.65), but not those in PAD and SAD. Only 17.4% of the included trials were considered to be high-quality, and this mostly affected the outcomes for PAD (g=0.61) and SAD (g=0.76). More than 80% of trials in anxiety disorders used waiting list control groups, and the few studies using other control groups pointed at much smaller effect sizes for CBT. We conclude that CBT is probably effective in the treatment of MDD, GAD, PAD and SAD; that the effects are large when the control condition is waiting list, but small to moderate when it is care as-usual or pill placebo; and that, because of the small number of high-quality trials, these effects are still uncertain and should be considered with caution.

PMID- 27717262 TI - Abandoning personalization to get to precision in the pharmacotherapy of depression. AB - Effectiveness studies and analyses of naturalistic cohorts demonstrate that many patients with major depressive disorder do not experience symptomatic remission with antidepressant treatments. In an effort to better match patients with effective treatments, numerous investigations of predictors or moderators of treatment response have been reported over the past five decades, including clinical features as well as biological measures. However, none of these have entered routine clinical practice; instead, clinicians typically personalize treatment on the basis of patient preferences as well as their own. Here, we review the reasons why it has been challenging to identify and deploy treatment specific predictors of response, and suggest strategies that may be required to achieve true precision in the pharmacotherapy of depression. We emphasize the need for changes in how depression care is delivered, measured, and used to inform future practice. PMID- 27717264 TI - Carving depression at its joints? PMID- 27717258 TI - Traditional marijuana, high-potency cannabis and synthetic cannabinoids: increasing risk for psychosis. AB - Epidemiological evidence demonstrates that cannabis use is associated with an increased risk of psychotic outcomes, and confirms a dose-response relationship between the level of use and the risk of later psychosis. High-potency cannabis and synthetic cannabinoids carry the greatest risk. Experimental administration of tetrahydrocannabinol, the active ingredient of cannabis, induces transient psychosis in normal subjects, but this effect can be ameliorated by co administration of cannabidiol. This latter is a constituent of traditional hashish, but is largely absent from modern high-potency forms of cannabis. Argument continues over the extent to which genetic predisposition is correlated to, or interacts with, cannabis use, and what proportion of psychosis could be prevented by minimizing heavy use. As yet, there is not convincing evidence that cannabis use increases risk of other psychiatric disorders, but there are no such doubts concerning its detrimental effect on cognitive function. All of the negative aspects are magnified if use starts in early adolescence. Irrespective of whether use of cannabis is decriminalized or legalized, the evidence that it is a component cause of psychosis is now sufficient for public health messages outlining the risk, especially of regular use of high-potency cannabis and synthetic cannabinoids.

AB - There exists a general consensus that prolonged grief disorder (PGD), or some variant of PGD, represents a distinct mental disorder worthy of diagnosis and treatment. Nevertheless, confusion remains over whether different names and proposed symptom criteria for this disorder identify the same or different diagnostic entities. This study aimed to determine whether PGD, complicated grief (CG), and persistent complex bereavement disorder (PCBD) as described by the DSM 5 are substantively or merely semantically different diagnostic entities. Data were derived from the Yale Bereavement Study, a longitudinal community-based study of bereaved individuals funded by the US National Institute of Mental Health, designed explicitly to evaluate diagnostic criteria for disordered grief. The results suggested that the difference between PGD and PCBD is only semantic. The level of agreement between the original PGD test, a new version of the PGD test proposed for ICD-11 and the PCBD test was high (pairwise kappa coefficients = 0.80-0.84). Their estimates of rate of disorder in this community sample were similarly low (~10%). Their levels of diagnostic specificity were comparably high (95.0-98.3%). Their predictive validity was comparable. In contrast, the test for CG had only moderate agreement with those for PGD and PCBD; its estimate of rate of disorder was three-fold higher (~30%); its diagnostic specificity was poorer, and it had no predictive validity. We conclude that PGD, PCBD and proposed ICD 11, but not CG, symptom-diagnostic tests identify a single diagnostic entity. Ultimately, brief symptom-diagnostic tests, such as the one proposed here for ICD 11, may have the greatest clinical utility.

AB - In the World Health Organization's forthcoming eleventh revision of the International Classification of Diseases and Related Health Problems (ICD-11), substantial changes have been proposed to the ICD-10 classification of mental and behavioural disorders related to sexuality and gender identity. These concern the following ICD-10 disorder groupings: F52 Sexual dysfunctions, not caused by organic disorder or disease; F64 Gender identity disorders; F65 Disorders of sexual preference; and F66 Psychological and behavioural disorders associated with sexual development and orientation. Changes have been proposed based on advances in research and clinical practice, and major shifts in social attitudes and in relevant policies, laws, and human rights standards. This paper describes the main recommended changes, the rationale and evidence considered, and important differences from the DSM-5. An integrated classification of sexual dysfunctions has been proposed for a new chapter on Conditions Related to Sexual Health, overcoming the mind/body separation that is inherent in ICD-10. Gender identity disorders in ICD-10 have been reconceptualized as Gender incongruence, and also proposed to be moved to the new chapter on sexual health. The proposed classification of Paraphilic disorders distinguishes between conditions that are relevant to public health and clinical psychopathology and those that merely reflect private behaviour. ICD-10 categories related to sexual orientation have been recommended for deletion from the ICD-11.

We explored the predictive value of ultra high risk (UHR) criteria in a sample of patients with 22q11DS. We also examined the additional contribution of socio-demographic, clinical and cognitive variables to predict transition to psychosis within a mean interval of 32.5 +/- 17.6 months after initial assessment. Eighty-nine participants with 22q11DS (age range: 8-30 years; mean 16.1 +/- 4.7) were assessed using the Structured Interview for Psychosis-Risk Syndromes. Information on Axis I diagnoses, internalizing and externalizing symptoms, level of functioning and IQ was also collected. At baseline, 22 (24.7%) participants met UHR criteria. Compared to those without a UHR condition, they had a significantly lower functioning, more frequent anxiety disorders, and more severe psychopathology. Transition rate to psychosis was 27.3% in UHR and 4.5% in non-UHR participants. Cox regression analyses revealed that UHR status significantly predicted conversion to psychosis. Baseline level of functioning was the only other additional predictor. This is the first study investigating the predictive value of UHR criteria in 22q11DS. It indicates that the clinical path leading to psychosis is broadly comparable to that observed in other clinical high-risk samples. Nevertheless, the relatively high transition rate in non-UHR individuals suggests that other risk markers should be explored in this population. The role of low functioning as a predictor of transition to psychosis should also be investigated more in depth.

AB - We report the case of a human immunodeficiency virus-seropositive patient whose initial kidney transplant failed because of BK polyomavirus-induced nephropathy, and who underwent a second transplantation 3 years later. BK viruria was detected 1 day after transplantation. After 1 month, BK viremia developed along with a donor-specific antibody. After decreasing tacrolimus and mycophenolic acid and 2 courses of intravenous immunoglobulins, BK viremia and donor-specific antibody permanently disappeared, with stable renal function. PMID- 27717280 TI - Evaluation of fibronectin 1 in one dried blood spot and in urine after rhGH treatment. AB - Since the appearance of recombinant human growth hormone (rhGH) in the 1980s, its expansion and acquisition through the black market has increased, so the detection of its abuse continues to be a challenge. New biomarkers that are more reliable and sensitive, allowing a larger detection window, are still needed. In this line, Fibronectin 1 (FN1) has been proposed as a potential genetic and protein biomarker of rhGH abuse in peripheral blood lymphocytes, serum, and plasma. However, logistic problems associated with current blood collection in sports drug testing point towards potential new alternative matrices that could be good candidates to be evaluated. Results obtained in this study showed high ELISA FN1 levels in one dried blood spot and in urine samples in ten healthy male volunteers treated with rhGH. Results showed that especially dried blood spots appear as a potential good matrix to detect rhGH abuse by means of FN1 biomarker. Copyright (c) 2016 John Wiley & Sons, Ltd. PMID- 27717281 TI - Computed Tomography-Guided Percutaneously Controlled Ablation of the Thoracic Paravertebral Nerve Due to Thoracic Neuropathic Pain. AB - BACKGROUND: Patients with thoracic neuropathic pain often do not respond to medication and physical therapy. Coblation technology has been demonstrated to have potential for pain management. METHODS: Fifteen patients underwent computed tomography-guided percutaneous coblation to ablate the thoracic paravertebral nerve for their medication-resistant thoracic neuropathic pain. The pain intensity was assessed by visual analog scale (VAS) 1 day before surgery and 1 week and 1, 3, and 6 months after surgery, and the difference between preoperative and postoperative VAS values was determined to evaluate the pain relief effectiveness. Patients who achieved > 50% pain relief were defined as responders, and the ratio in all patients was calculated. The number of patients who reported mild pain (VAS <= 3) was recorded, and the ratio in all responders was calculated. In addition, adverse effects were also recorded to investigate the security of procedure. RESULTS: Twelve (80%) responders achieved > 50% pain relief. The VAS score of responders significantly decreased from 7.42 +/- 1.38 before surgery to 2.17 +/- 1.11 (P = 0.000), 1.92 +/- 1.16 (P = 0.000), 1.75 +/- 0.97 (P = 0.000), and 1.58 +/- 1.08 (P = 0.000) at 1 week, 1, 3, and 6 months after surgery, respectively. The number of responders with mild pain was 10 (83.3%), 11 (91.7%), 12 (100%), and 12 (100%) at 1 week, 1, 3, and 6 months after surgery, respectively. All responders and 1 nonresponder reported slight numbness after the surgery. CONCLUSION: Percutaneous thoracic paravertebral nerve coblation guided by computed tomography is a potential method for the treatment of thoracic neuropathic pain. PMID- 27717282 TI - Multi-Responsive "Turn-On" Nanocarriers for Efficient Site-Specific Gene Delivery In Vitro and In Vivo. AB - Systemic gene delivery is a complicated and multistep process that confronts numerous biological barriers. It remains a formidable challenge to exploit a single gene carrier with multiple features to combat all obstacles collectively. Herein, a multi-responsive "turn-on" polyelectrolyte complex (DNA/OEI-SSx /HA-SS COOH, DSS) delivery system is demonstrated with a sequential self-assembly of disulfide-conjugated oligoethylenimine (OEI-SSx ) and disulfide bond-modified hyaluronic acid envelope (HA-SS-COOH) that can combat multiple biological barriers collectively when administered intravenously. DSS is designed to effectively accumulate at the tumor tissue and to be internalized into tumor cells by recognizing CD44. The multi-responsive "turn-on" DSS can respond to the alterations of hyaluronidases and glutathione at both the tumor site and at the intracellular milieu. Sequential degradation and detachment of the HA-SS-COOH envelope followed by the dissociation of the OEI-SSx/DNA inner core contributes to the activation of the endosomal escape and gene release functions, thus greatly enhancing nuclear gene delivery. A systematic investigation of DSS has revealed that the tumor accumulation ability, internalization, and endosome escape of the DSS nanocarriers, DNA unpacking and nuclear transportation are all remarkably improved by the multi-responsive "turn-on" design resulting in highly efficient gene transfection in vitro and in vivo. PMID- 27717285 TI - Barrierless Switching Between a Liquid and Superheated Solid Catalyst During Nanowire Growth. AB - Knowledge of nucleation and growth mechanisms is essential for the synthesis of nanomaterials, such as semiconductor nanowires, with shapes and compositions precisely engineered for technological applications. Nanowires are conventionally grown by the seemingly well-understood vapor-liquid-solid mechanism, which uses a liquid alloy as the catalyst for growth. However, we show that it is possible to instantaneously and reversibly switch the phase of the catalyst between a liquid and superheated solid state under isothermal conditions above the eutectic temperature. The solid catalyst induces a vapor-solid-solid growth mechanism, which provides atomic-level control of dopant atoms in the nanowire. The switching effect cannot be predicted from equilibrium phase diagrams but can be explained by the dominant role of the catalyst surface in modulating the kinetics and thermodynamics of phase behavior. The effect should be general to metal catalyzed nanowire growth and highlights the unexpected yet technologically relevant non-equilibrium effects that can emerge in the growth of nanoscale systems. PMID- 27717283 TI - Proteomic and phosphoproteomic analyses of yeast reveal the global cellular response to sphingolipid depletion. AB - Sphingolipids are essential components of eukaryotic cells with important functions in membrane biology and cellular signaling. Their levels are tightly controlled and coordinated with the abundance of other membrane lipids. How sphingolipid homeostasis is achieved is not yet well understood. Studies performed primarily in yeast showed that the phosphorylation states of several enzymes and regulators of sphingolipid synthesis are important, although a global understanding for such regulation is lacking. Here, we used high-resolution MS based proteomics and phosphoproteomics to analyze the cellular response to sphingolipid synthesis inhibition. Our dataset reveals that changes in protein phosphorylation, rather than protein abundance, dominate the response to blocking sphingolipid synthesis. We identified Ypk signaling as a pathway likely to be activated under these conditions, and we identified potential Ypk1 target proteins. Our data provide a rich resource for on-going mechanistic studies of key elements of the cellular response to the depletion of sphingolipid levels and the maintenance of sphingolipid homeostasis. All MS data have been deposited in the ProteomeXchange with identifier PXD003854 (http://proteomecentral.proteomexchange.org/dataset/PXD003854). PMID- 27717284 TI - Young investigator challenge: The morphologic analysis of noninvasive follicular thyroid neoplasm with papillary-like nuclear features on liquid-based cytology: Some insights into their identification. AB - BACKGROUND: Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) represents a challenge for the diagnosis and management of thyroid carcinoma. Some authors have proposed histological criteria that are able to distinguish NIFTPs from invasive follicular variant of papillary thyroid carcinoma (I-FVPTC). Hence, NIFTPs may have repercussions in the diagnostic categories on fine-needle aspiration. In the current study, the authors evaluated the criteria for NIFTPs on liquid-based cytology samples. METHODS: The authors recorded all 61 liquid-based cytology samples proved to be histological FVPTC between January 2013 and March 2016 and analyzed the architectural, cytoplasmic, and nuclear parameters. They compared them with a cohort of 40 PTC cases and 20 follicular adenoma cases. RESULTS: The authors reported 37 NIFTP cases and 24 I FVPTC cases at histology. The cytological diagnoses of follicular nodules in the NIFTP cases were twice those found in the I-FVPTC cases (54.1% vs 29.2%). The number of positive for malignancy cases among the NIFTPs were approximately half those of I-FVPTC cases. When compared with I-FVPTCs, 70% of the NIFTP cases demonstrated a nuclear size <20 MUm (P = .025) and rarely exhibited grooves (13% vs 42%; P = .009). The authors found 100% of cases with wild-type BRAF gene in NIFTP cases versus 38.4% in mutated I-FVPTC cases (P = .046). The cytoplasmic features might help to discriminate NIFTPs from follicular adenomas but not from I-FVPTCs (P>.05). A predominant microfollicular pattern was recognized in both NIFTPs and I-FVPTCs (97.3% vs 100%). CONCLUSIONS: The majority of NIFTPs appear to be devoid of nuclear pseudoinclusions and papillary structures, thereby allowing the inclusion in the follicular nodule cases. Nuclear size and microfollicular clusters may suggest the discrimination between NIFTPs and I FVPCs. Cancer Cytopathol 2016;124:699-710. (c) 2016 American Cancer Society. PMID- 27717286 TI - Combination of Liquid Chromatography with Multivariate Curve Resolution Alternating Least-Squares (MCR-ALS) in the Quantitation of Polycyclic Aromatic Hydrocarbons Present in Paprika Samples. AB - This work presents a strategy for quantitating polycyclic aromatic hydrocarbons (PAHs) in smoked paprika samples. For this, a liquid chromatographic method with fluorimetric detection (HPLC-FLD) was optimized. To resolve some interference co eluting with the target analytes, the second-order multivariate curve resolution alternating least-squares (MCR-ALS) algorithm has been employed combined with this liquid chromatographic method. Among the eight PAHs quantified (fluorene, phenanthrene, anthracene, pyrene, chrysene, benzo[a]anthracene, benzo[b]fluoranthene, and benzo[a]pyrene) by HPLC-FLD, only in the case of fluorene, pyrene, and benzo[b]fluoranthene was it necessary to apply the second order algorithm for their resolution. Limits of detection and quantitation were between 0.015 and 0.45 mg/kg and between 0.15 and 1.5 mg/kg, respectively. Good recovery results (>80%) for paprika were obtained via the complete extraction procedure, consisting of an extraction from the matrix and the cleanup of the extract by means of silica cartridges. Higher concentrations of chrysene, benzo[a]anthracene, benzo[b]fluoranthene, and benzo[a]pyrene were found in the paprika samples, with respect to the maximal amounts allowed for other spices that are under European Regulation (EU) N degrees 2015/1933. PMID- 27717287 TI - Cocaine Vaccine Development: Evaluation of Carrier and Adjuvant Combinations That Activate Multiple Toll-Like Receptors. AB - Although cocaine abuse and addiction continue to cause serious health and societal problems, an FDA-approved medication to treat cocaine addiction has yet to be developed. Employing a pharmacokinetic strategy, an anticocaine vaccine provides an attractive avenue to address these issues; however, current vaccines have shown varying degrees of efficacy, indicating that further formulation is necessary. As a means to improve vaccine efficacy, we examined the effects of varying anticocaine vaccine formulations by combining a Toll-like receptor 9 (TLR9) agonist with a TLR5 agonist in the presence of alum. The TLR9 agonist used was cytosine-guanine oligodeoxynucleotide 1826 (CpG 1826), while the TLR5 agonist was flagellin (FliC). Formulations with the TLR9 agonist elicited superior anticocaine antibody titers and blockade of hyperlocomotor effects compared to vaccines without CpG 1826. This improvement was seen regardless of whether the TLR5 agonist, FliC, or the nonadjuvanting Tetanus Toxoid (TT) was used as the carrier protein. Additional insights into the value of FliC as a carrier versus adjuvant was also investigated by generating two unique formats of the protein, wild-type and mutated flagellin (mFliC). While the mFliC conjugate retained its ability to stimulate mTLR5, it yielded reduced cocaine sequestration and functional blockade relative to FliC and TT. Overall, this work indicates that activation of TLR9 can improve the function of cocaine vaccines in the presence of TLR5 activation by FliC, with any potential additive effects limited by the inefficiency of FliC as a carrier protein as compared to TT. PMID- 27717288 TI - Influence of Chirality of Lactones on the Perception of Some Typical Fruity Notes through Perceptual Interaction Phenomena in Bordeaux Dessert Wines. AB - Recent studies concerning the aroma of noble rot dessert wines revealed the importance of a well-known phenomenon in perfumery, the perceptual blending, to create the perception of "overripe orange" nuances. Thus, compounds associated with both oak wood aging (3-methyl-4-octanolide and eugenol) and Botrytis cinerea development under the form of noble rot (2-nonen-4-olide and gamma-nonalactone) contribute to a specific aroma of great noble rot dessert wines through perceptual interaction phenomena. This synthetic perception phenomenon was established from reconstitution, addition, and omission sensory experiments, using wine extract fractions supplemented with the volatile compounds previously mentioned. To better understand the sensory impact of these compounds, the goal of this research was to study the contributions of enantiomeric forms of 2-nonen 4-olide and gamma-nonalactone and the diastereoisomers of 3-methyl-4-octanolide. After multidimensional chiral chromatography analysis, the relative proportions of enantiomers or diastereomeric forms were first established and then sensory experiments were carried out using the reference compounds with isolated fractions from dessert wines. A dominance of the R form was established for 2 nonen-4-olide, which was correlated with wine aging, while the S form is more dominant in young dessert wines. Furthermore, the reconstitution experiments confirmed perceptual interaction phenomena and revealed the sensory contribution of (R)-2-nonen-4-olide and cis-3-methyl-4-octanolide concerning the "overripe orange" nuances, whereas no sensory impact for the gamma-nonalactone isomers was observed. PMID- 27717289 TI - Response of growing goslings to dietary supplementation with methionine and betaine. AB - An experiment with a 2 * 3 factorial design with two concentrations of dietary betaine (0 and 600 mg/kg) and three dietary concentrations of methionine (0, 600 and 1200 mg/kg) was conducted using goslings to estimate growth, nutrient utilisation and digestibility of amino acids from 21 to 70 d of age. Three hundred geese were randomised at 18 d of age into 6 groups with 5 replicates per treatment and 10 geese per replicate. Increasing dietary concentrations of methionine gave a linear increase in body weight and average daily gain. The coefficient of crude fat retention increased as dietary methionine increased and there was a significant non-linear response to increasing dietary methionine. Similarly, increasing supplemental methionine gave linear increases in the digestibility of methionine and cysteine. The results of this study indicated that optimal dietary supplementation of methionine could increase growth performance and methionine and cysteine utilisation in growing goslings. Betaine supplementation had no apparent sparing effect on methionine needs for growth performance, but did improve the apparent cysteine digestibility. PMID- 27717290 TI - Mycotoxin in the food supply chain-implications for public health program. AB - Mycotoxins are a group of naturally occurring toxic chemical substances, produced mainly by microscopic filamentous fungal species. Regarding potential synergisms or even mitigating effects between toxic elements, mycotoxin contamination will continue to be an area of concern for producers, manufacturers, regulatory agencies, researchers, and consumers in the future. In Serbia, recent drought and then flooding confirmed that mycotoxins are one of the foodborne hazards most susceptible to climate change. In this article, we review key aspects of mycotoxin contamination of the food supply chain and implications for public health from the Serbian perspective. PMID- 27717291 TI - Turbulent eddy diffusion models in exposure assessment - Determination of the eddy diffusion coefficient. AB - The use of the turbulent eddy diffusion model and its variants in exposure assessment is limited due to the lack of knowledge regarding the isotropic eddy diffusion coefficient, DT. But some studies have suggested a possible relationship between DT and the air changes per hour (ACH) through a room. The main goal of this study was to accurately estimate DT for a range of ACH values by minimizing the difference between the concentrations measured and predicted by eddy diffusion model. We constructed an experimental chamber with a spatial concentration gradient away from the contaminant source, and conducted 27 3-hr long experiments using toluene and acetone under different air flow conditions (0.43-2.89 ACHs). An eddy diffusion model accounting for chamber boundary, general ventilation, and advection was developed. A mathematical expression for the slope based on the geometrical parameters of the ventilation system was also derived. There is a strong linear relationship between DT and ACH, providing a surrogate parameter for estimating DT in real-life settings. For the first time, a mathematical expression for the relationship between DT and ACH has been derived that also corrects for non-ideal conditions, and the calculated value of the slope between these two parameters is very close to the experimentally determined value. The values of DT obtained from the experiments are generally consistent with values reported in the literature. They are also independent of averaging time of measurements, allowing for comparison of values obtained from different measurement settings. These findings make the use of turbulent eddy diffusion models for exposure assessment in workplace/indoor environments more practical. PMID- 27717292 TI - Reduction in ulnar pressure distribution when walking with forearm crutches with a novel cuff design: Cross-sectional intervention study on the biomechanical efficacy of an ulnar recess. AB - Walking with crutches is an effective way of reducing the load on the lower extremity and is often indicated after injury or surgery. However, walking with forearm crutches with conventional cuffs can trigger symptoms including tenosynovitis in the biceps tendon, ulnar neuropraxia at the wrist, pain, or skin hematoma. The purpose of this study was to test the hypothesis that a crutch cuff design with an ulnar recess reduces ulnar pressure during walking with forearm crutches. The pressure distribution between the forearm and crutch cuff was measured in 15 healthy participants for crutch walking with conventional and novel cuffs, respectively. Relative peak pressure in the proximal medial region compared to the overall peak pressure was reduced by 8.6% when walking with crutches with the novel cuff design compared to conventional cuffs (p < 0.001). Relative peak pressure in the distal intermediate and lateral regions were increased by 3.3% and 3.7% for the novel compared with conventional cuffs, respectively (p < 0.001 for both). Hence, the novel crutch cuffs shifted regions of high pressure away from the proximal ulnar region towards more distal regions that are covered by more soft tissue. PMID- 27717293 TI - Is One Early Renographic Follow-Up Adequate to Measure the Success of Robotic Pyeloplasty? AB - PURPOSE: Diuretic renography (DRG) is commonly used to diagnose ureteropelvic junction obstruction (UPJO) and to evaluate the success of surgical repair (pyeloplasty). Duration, frequency, and interpretation of renographic follow-ups are still under dispute. METHODS: We retrospectively reviewed 94 consecutive patients diagnosed with UPJO who underwent a minimally invasive, robotically assisted laparoscopic pyeloplasty at our institution between January 2009 and September 2015. DRG was carried out preoperatively and again routinely 4 to 6 weeks postoperatively the day after stent removal (early DRG). Patients were scheduled for repeat (late) DRG and follow-up examinations, including clinical status and ultrasonography. RESULTS: Nineteen patients with missing preoperative DRG were excluded from the study; the remaining 75 patients were eligible for statistical evaluation. At follow-up, 98.7% reported no or only very mild and rare symptoms. On early DRG, 52.5% had T1/2 <= 10 min (unobstructed), 39.3% had T1/2 between 10 and 20 minutes (equivocal), and 8.2% had T1/2 <= 20 minutes (obstructed). At late follow-up, the DRG results had improved to 80.8% unobstructed with 19.2% remaining equivocal, and no patients were obstructed; thus, the overall success rate was 80.8%. There was only one patient who worsened from unobstructed to equivocal from early to late DRG assessment. CONCLUSION: In case of complete symptom resolution, a nonobstructive diuretic half-time of <=10 minutes on early DRG following stent removal suggests that further routine renographic follow-up is unnecessary. Patients with an equivocal early DRG (T1/2 between 10 and 20 minutes) require further scintigraphic follow-up, as they have a 42.1% chance of staying equivocal. PMID- 27717294 TI - Wastewater and sludge management and research in Oman: An overview. AB - : It is well recognized that management of wastewater and sludge is a critical environmental issue in many countries. Wastewater treatment and sludge production take place under different technical, economic, and social contexts, thus requiring different approaches and involving different solutions. In most cases, a regular and environmentally safe wastewater treatment and associated sludge management requires the development of realistic and enforceable regulations, as well as treatment systems appropriate to local circumstances. The main objective of this paper is to provide useful information about the current wastewater and sludge treatment, management, regulations, and research in Oman. Based on the review and discussion, the wastewater treatment and sludge management in Oman has been evolving over the years. Further, the land application of sewage sludge should encourage revision of existing standards, regulations, and policies for the management and beneficial use of sewage sludge in Oman. IMPLICATIONS: Wastewater treatment and sludge management in Oman have been evolving over the years. Sludge utilization has been a challenge due to its association with human waste. Therefore, composting of sewage sludge is the best option in agriculture activities. Sludge and wastewater utilization can add up positively in the economic aspects of the country in terms of creating jobs and improving annual income rate. The number of research projects done on wastewater reuse and other ongoing ones related to the land application of sewage sludge should encourage revision of existing standards, regulations, and policies for the management and beneficial use of sewage sludge in Oman. PMID- 27717295 TI - Cognitive Impairment and Mood States after Spinal Cord Injury. AB - Spinal cord injury (SCI) is believed to be associated with high rates of cognitive impairment, which can result in complications in recovery. This study concerned two groups of adults with SCI. The first sample involved 150 participants with SCI who were assessed once for cognitive capacity with comparisons made with 45 able-bodied adults. Sample 2 were drawn from Sample 1, and included 88 participants with SCI who were prospectively assessed for mood states (anxiety, depressive mood, and fatigue) and pain intensity at three time periods: at admission to SCI rehabilitation, at discharge, and 6 months after transition into the community. Results showed that the SCI sample had significantly lower cognitive performance than the able-bodied control group. Further, almost 29% of the adults with SCI had lowered cognitive performance believed to be indicative of cognitive impairment. The risk of an adult with SCI having cognitive impairment was almost 13 times that of someone without an SCI. Results from Sample 2 revealed that the development of negative mood states was a significant problem in those with cognitive impairment after they transitioned into the community, a time when personal resources are severely challenged. Findings suggest all adults with SCI admitted to rehabilitation should receive a cognitive screen, and that rehabilitation strategies should then be guided by the cognitive performance of the person. Special attention should also be given to improving skills of those with cognitive impairment before they transition into the community, so as to reduce risk of comorbid mental health problems. PMID- 27717296 TI - Cystine Stone Formers Have Impaired Health-Related Quality of Life Compared with Noncystine Stone Formers: A Case-Referent Study Piloting the Wisconsin Stone Quality of Life Questionnaire Among Patients with Cystine Stones. AB - INTRODUCTION: Cystinuria is a rare cause of urolithiasis. Affected patients have an earlier onset and more aggressive disease than patients with other stone etiologies. We assessed the health-related quality of life (HRQOL) of cystine stone-forming patients using the disease-specific Wisconsin Stone Quality of Life questionnaire (WISQOL). METHODS: Cystine patients treated in our stone clinics (n = 12) completed the WISQOL; information about medical and stone histories was gathered. Patients were matched with noncystine stone formers (n = 12) for gender, age, and comorbidities. In addition, a second control group (n = 90), also from our institution and consisting of mixed calcium stone formers, was included. WISQOL responses were compared between groups. RESULTS: Cystine patients had significantly lower total WISQOL scores than noncystine patients. Compared with noncystine stone formers, cystine stone formers also had lower HRQOL scores for subscales (domains) related to social impact, emotional impact, disease impact, and vitality (p <= 0.04 for all). On specific items, cystine patients reported significantly more sleep problems (p = 0.02), more bother with nocturia (p = 0.03), and feeling tired or fatigued (p = 0.02). Among those with current stones, cystine patients scored lower than noncystine patients for total score and in two of four domains. CONCLUSIONS: Using a stone-specific questionnaire, patients with cystine stones have lower HRQOL compared with noncystine stone formers. Identifying and addressing specific areas of decrement in patients with cystine stones may improve disease management and patients' HRQOL. PMID- 27717297 TI - Dysphagia progression and feeding skills following pediatric alkali ingestion injury: two case reports. AB - PURPOSE: There is limited information regarding the nature of dysphagia and feeding difficulties following alkali ingestion injury to inform multidisciplinary intervention. The aim was to describe the history and nature of chronic dysphagia and feeding difficulties in two children following severe alkali ingestion injury. METHODS: Medical records, primary caregiver report, and clinical assessment were used to compile detailed case histories and assess current dysphagia and feeding skills. RESULTS: Both cases demonstrated heterogeneous oral motor and feeding outcomes, including delayed oral motor skills, restricted dietary variety, and difficult mealtime behaviors that contributed to protracted recovery of age-appropriate PO intake. Both children required ongoing diet and/or fluid modification and supplemental non-PO feeding via gastrostomy at the time of review, that is, 2-year post-injury. CONCLUSIONS: Recovery from dysphagia post-alkali ingestion is protracted and complex. Dysphagia, delayed oral motor skills, and difficult mealtime behaviors may persist secondary to ingestion injury and its associated complications. These cases highlight the importance of considering early referral for feeding assessment and intervention to assist children and families with recovery. Progression through safe and effective oral (per os, PO) intake is needed, as well as provision of support for primary caregivers. Implications for Rehabilitation Pediatric chemical ingestion injury can cause long-term dysphagia and long-term feeding difficulties Initial injury severity does not reliably correlate with eventuating level of aerodigestive impairment. Clinical and instrumental assessment is required to monitor swallow function to enable commencement of targeted rehabilitation when appropriate. Early involvement of a feeding therapist is recommended to minimize the long-term effects on oral motor skill development, progression to age-appropriate diet, and provision of family centered care. PMID- 27717300 TI - Comparison of qualitative and quantitative fit-testing results for three commonly used respirators in the healthcare sector. AB - N95 filtering facepiece respirators are used by healthcare workers when there is a risk of exposure to airborne hazards during aerosol-generating procedures. Respirator fit-testing is required prior to use to ensure that the selected respirator provides an adequate face seal. Two common fit-test methods can be employed: qualitative fit-test (QLFT) or quantitative fit-test (QNFT). Respiratory protection standards deem both fit-tests to be acceptable. However, previous studies have indicated that fit-test results may differ between QLFT and QNFT and that the outcomes may also be influenced by the type of respirator model. The aim of this study was to determine if there is a difference in fit test outcomes with our suite of respirators, 3M - 1860S, 1860, AND 1870, and whether the model impacts the fit-test results. Subjects were recruited from residential care facilities. Each participant was assigned a respirator and underwent sequential QLFT and QNFT fit-tests and the results (either pass or fail) were recorded. To ascertain the degree of agreement between the two fit tests, a Kappa (Kappa) statistic was conducted as per the American National Standards Institute (ANSI) respiratory protection standard. The pass-fail rates were stratified by respirator model and a Kappa statistic was calculated for each to determine effect of model on fit-test outcomes. We had 619 participants and the aggregate Kappa statistic for all respirators was 0.63 which is below the suggested ANSI threshold of 0.70. There was no statistically significant difference in results when stratified by respirator model. QNFT and QLFT produced different fit-test outcomes for the three respirator models examined. The disagreement in outcomes between the two fit-test methods with our suite of N95 filtering facepiece respirators was approximately 12%. Our findings may benefit other healthcare organizations that use these three respirators. PMID- 27717301 TI - Respirable dust and silica exposure among World Trade Center cleanup workers. AB - The cleanup effort following the destruction of the World Trade Center (WTC) was unprecedented and involved removal of 1.8 million tons of rubble over a nine month period. Work at the site occurred 24 hr a day, 7 days a week and involved thousands of workers during the process. The Occupational Safety and Health Administration (OSHA) conducted personal and area exposure sampling during the cleanup of the site. Secondary data analysis was performed on OSHA air sampling data for respirable dust and silica from September 2001 to June 2002 at the WTC recovery site to characterize workers' exposure. Results for silica and respirable particulate were stratified by area and personal samples as well as job task for analysis. Of 1108 samples included in the analysis, 693 were personal and 415 were area. The mean result for personal silica samples was 42 MUg/m3 (Range: 4.2-1800 MUg/m3). Workers identified as drillers had the highest mean silica exposure (72 MUg/m3; range: 5.8-800 MUg/m3) followed by workers identified as dock builders (67 MUg/m3; range: 5.8-670 MUg/m3). The mean result for personal samples for respirable particulate was 0.44 mg/m3 (range: 0.00010-13 mg/m3). There were no discernable trends in personal respirable dust and silica concentrations with date. PMID- 27717298 TI - Prolonged Survival in Stage III Melanoma with Ipilimumab Adjuvant Therapy. AB - BACKGROUND: On the basis of data from a phase 2 trial that compared the checkpoint inhibitor ipilimumab at doses of 0.3 mg, 3 mg, and 10 mg per kilogram of body weight in patients with advanced melanoma, this phase 3 trial evaluated ipilimumab at a dose of 10 mg per kilogram in patients who had undergone complete resection of stage III melanoma. METHODS: After patients had undergone complete resection of stage III cutaneous melanoma, we randomly assigned them to receive ipilimumab at a dose of 10 mg per kilogram (475 patients) or placebo (476) every 3 weeks for four doses, then every 3 months for up to 3 years or until disease recurrence or an unacceptable level of toxic effects occurred. Recurrence-free survival was the primary end point. Secondary end points included overall survival, distant metastasis-free survival, and safety. RESULTS: At a median follow-up of 5.3 years, the 5-year rate of recurrence-free survival was 40.8% in the ipilimumab group, as compared with 30.3% in the placebo group (hazard ratio for recurrence or death, 0.76; 95% confidence interval [CI], 0.64 to 0.89; P<0.001). The rate of overall survival at 5 years was 65.4% in the ipilimumab group, as compared with 54.4% in the placebo group (hazard ratio for death, 0.72; 95.1% CI, 0.58 to 0.88; P=0.001). The rate of distant metastasis-free survival at 5 years was 48.3% in the ipilimumab group, as compared with 38.9% in the placebo group (hazard ratio for death or distant metastasis, 0.76; 95.8% CI, 0.64 to 0.92; P=0.002). Adverse events of grade 3 or 4 occurred in 54.1% of the patients in the ipilimumab group and in 26.2% of those in the placebo group. Immune related adverse events of grade 3 or 4 occurred in 41.6% of the patients in the ipilimumab group and in 2.7% of those in the placebo group. In the ipilimumab group, 5 patients (1.1%) died owing to immune-related adverse events. CONCLUSIONS: As adjuvant therapy for high-risk stage III melanoma, ipilimumab at a dose of 10 mg per kilogram resulted in significantly higher rates of recurrence free survival, overall survival, and distant metastasis-free survival than placebo. There were more immune-related adverse events with ipilimumab than with placebo. (Funded by Bristol-Myers Squibb; ClinicalTrials.gov number, NCT00636168 , and EudraCT number, 2007-001974-10 .).

AB - BACKGROUND: Niraparib is an oral poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) 1/2 inhibitor that has shown clinical activity in patients with ovarian cancer. We sought to evaluate the efficacy of niraparib versus placebo as maintenance treatment for patients with platinum-sensitive, recurrent ovarian cancer. METHODS: In this randomized, double-blind, phase 3 trial, patients were categorized according to the presence or absence of a germline BRCA mutation (gBRCA cohort and non-gBRCA cohort) and the type of non-gBRCA mutation and were randomly assigned in a 2:1 ratio to receive niraparib (300 mg) or placebo once daily. The primary end point was progression-free survival. RESULTS: Of 553 enrolled patients, 203 were in the gBRCA cohort (with 138 assigned to niraparib and 65 to placebo), and 350 patients were in the non-gBRCA cohort (with 234 assigned to niraparib and 116 to placebo). Patients in the niraparib group had a significantly longer median duration of progression-free survival than did those in the placebo group, including 21.0 vs. 5.5 months in the gBRCA cohort (hazard ratio, 0.27; 95% confidence interval [CI], 0.17 to 0.41), as compared with 12.9 months vs. 3.8 months in the non-gBRCA cohort for patients who had tumors with homologous recombination deficiency (HRD) (hazard ratio, 0.38; 95% CI, 0.24 to 0.59) and 9.3 months vs. 3.9 months in the overall non-gBRCA cohort (hazard ratio, 0.45; 95% CI, 0.34 to 0.61; P<0.001 for all three comparisons). The most common grade 3 or 4 adverse events that were reported in the niraparib group were thrombocytopenia (in 33.8%), anemia (in 25.3%), and neutropenia (in 19.6%), which were managed with dose modifications. CONCLUSIONS: Among patients with platinum sensitive, recurrent ovarian cancer, the median duration of progression-free survival was significantly longer among those receiving niraparib than among those receiving placebo, regardless of the presence or absence of gBRCA mutations or HRD status, with moderate bone marrow toxicity.

PMID- 27717302 TI - MiR-20b Displays Tumor-Suppressor Functions in Papillary Thyroid Carcinoma by Regulating the MAPK/ERK Signaling Pathway. AB - BACKGROUND: MicroRNAs (miRNAs) are endogenous, small, non-coding RNAs that play important roles in multiple biological processes. MiR-20b has been reported to be dysregulated in papillary thyroid carcinoma (PTC). However, the functional roles are still largely unknown. This study aimed to investigate the biological functions and the underlying molecular mechanisms of miR-20b in PTC. METHOD: The expression of miR-20b was assessed by quantitative reverse transcription polymerase chain reaction in 47 pairs of PTC and adjacent normal thyroid tissues. The association between miR-20b expression and clinicopathologic status of PTC patients was analyzed. MiR-20b was overexpressed in the PTC cell lines K1 and TPC 1, and the effects on cell viability, migration, and invasion were evaluated. The study further searched for targets of miR-20b, and identified the possible molecular mechanisms of miR-20b in PTC cells. Additionally, the effect of miR-20b on tumor growth in nude mice was assessed. RESULTS: It was found that miR-20b was markedly downregulated in PTC tissues compared with their adjacent normal thyroid tissues. The low-level expression of miR-20b was correlated with cervical lymph node metastasis and TNM staging. Upregulation of miR-20b inhibited cell viability, migration, and invasion in K1 and TPC-1 cells. Ectopic overexpression of miR-20b could suppress the mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) signaling pathway through directly targeting son of sevenless homolog 1 (SOS1) and extracellular signal-regulated kinase 2 (ERK2). Furthermore, depletion of SOS1 or ERK2 by siRNAs has similar effects as miR-20b overexpression on cell viability and invasion, whereas rescued SOS1 or ERK2 expression partially reversed the inhibitory effects of miR-20b in TPC cell lines. In xenograft animal experiments, it was found that overexpressed miR-20b could suppress tumor growth of PTC cells. CONCLUSION: These results indicate for the first time that miR-20b displays tumor-suppressor functions in PTC. By targeting SOS1 and ERK2, miR-20b inhibits the activity of the MAPK/ERK signaling pathway. The findings suggest that miR-20b may play an important role in PTC initiation, progression, and metastasis, and may provide a potential therapeutic target for PTC. PMID- 27717304 TI - Je, a versatile suite to handle multiplexed NGS libraries with unique molecular identifiers. AB - BACKGROUND: The yield obtained from next generation sequencers has increased almost exponentially in recent years, making sample multiplexing common practice. While barcodes (known sequences of fixed length) primarily encode the sample identity of sequenced DNA fragments, barcodes made of random sequences (Unique Molecular Identifier or UMIs) are often used to distinguish between PCR duplicates and transcript abundance in, for example, single-cell RNA sequencing (scRNA-seq). In paired-end sequencing, different barcodes can be inserted at each fragment end to either increase the number of multiplexed samples in the library or to use one of the barcodes as UMI. Alternatively, UMIs can be combined with the sample barcodes into composite barcodes, or with standard Illumina(r) indexing. Subsequent analysis must take read duplicates and sample identity into account, by identifying UMIs. RESULTS: Existing tools do not support these complex barcoding configurations and custom code development is frequently required. Here, we present Je, a suite of tools that accommodates complex barcoding strategies, extracts UMIs and filters read duplicates taking UMIs into account. Using Je on publicly available scRNA-seq and iCLIP data containing UMIs, the number of unique reads increased by up to 36 %, compared to when UMIs are ignored. CONCLUSIONS: Je is implemented in JAVA and uses the Picard API. Code, executables and documentation are freely available at http://gbcs.embl.de/Je . Je can also be easily installed in Galaxy through the Galaxy toolshed. PMID- 27717303 TI - Ribociclib as First-Line Therapy for HR-Positive, Advanced Breast Cancer. AB - BACKGROUND: The inhibition of cyclin-dependent kinases 4 and 6 (CDK4/6) could potentially overcome or delay resistance to endocrine therapy in advanced breast cancer that is positive for hormone receptor (HR) and negative for human epidermal growth factor receptor 2 (HER2). METHODS: In this randomized, placebo controlled, phase 3 trial, we evaluated the efficacy and safety of the selective CDK4/6 inhibitor ribociclib combined with letrozole for first-line treatment in 668 postmenopausal women with HR-positive, HER2-negative recurrent or metastatic breast cancer who had not received previous systemic therapy for advanced disease. We randomly assigned the patients to receive either ribociclib (600 mg per day on a 3-weeks-on, 1-week-off schedule) plus letrozole (2.5 mg per day) or placebo plus letrozole. The primary end point was investigator-assessed progression-free survival. Secondary end points included overall survival, overall response rate, and safety. A preplanned interim analysis was performed on January 29, 2016, after 243 patients had disease progression or died. Prespecified criteria for superiority required a hazard ratio of 0.56 or less with P<1.29*10-5. RESULTS: The duration of progression-free survival was significantly longer in the ribociclib group than in the placebo group (hazard ratio, 0.56; 95% CI, 0.43 to 0.72; P=3.29*10-6 for superiority). The median duration of follow-up was 15.3 months. After 18 months, the progression-free survival rate was 63.0% (95% confidence interval [CI], 54.6 to 70.3) in the ribociclib group and 42.2% (95% CI, 34.8 to 49.5) in the placebo group. In patients with measurable disease at baseline, the overall response rate was 52.7% and 37.1%, respectively (P<0.001). Common grade 3 or 4 adverse events that were reported in more than 10% of the patients in either group were neutropenia (59.3% in the ribociclib group vs. 0.9% in the placebo group) and leukopenia (21.0% vs. 0.6%); the rates of discontinuation because of adverse events were 7.5% and 2.1%, respectively. CONCLUSIONS: Among patients receiving initial systemic treatment for HR-positive, HER2-negative advanced breast cancer, the duration of progression-free survival was significantly longer among those receiving ribociclib plus letrozole than among those receiving placebo plus letrozole, with a higher rate of myelosuppression in the ribociclib group.

PMID- 27717305 TI - A novel method for quantifying the rate of embryogenesis uncovers considerable genetic variation for the duration of embryonic development in Drosophila melanogaster. AB - BACKGROUND: Embryogenesis is a highly conserved, canalized process, and variation in the duration of embryogenesis (DOE), i.e., time from egg lay to hatching, has a potentially profound effect on the outcome of within- and between-species competition. There is both intra- and inter-specific variation in this trait, which may provide important fuel for evolutionary processes, particularly adaptation. However, while genetic variation underlying simpler morphological traits, or with large phenotypic effects is well described in the literature, less is known about the underlying genetics of traits, such as DOE, partly due to a lack of tools with which to study them. RESULTS: Here, we establish a novel microscope-based assay to survey genetic variation for the duration of embryogenesis (DOE). First, to establish the potential importance of DOE in competitive fitness, we performed a set of experiments where we experimentally manipulated the time until hatching, and show that short hatching times result in priority effect in the form of improved larval competitive ability. We then use our assay to measure DOE for 43 strains from the Drosophila Genetic Reference Panel (DGRP). Our assay greatly simplifies the measurement of DOE, making it possible to precisely quantify this trait for 59,295 individual embryos (mean +/- S.D. of 1103 +/- 293 per DGRP strain, and 1002 +/- 203 per control). We find extensive genetic variation in DOE, with a 15 % difference in rate between the slowest and fastest strains measured, and 89 % of phenotypic variation due to DGRP strain. Using sequence information from the DGRP, we perform a genome-wide association study, which suggests that some well-known developmental genes affect the speed of embryonic development. CONCLUSIONS: We showed that the duration of embryogenesis (DOE) can be efficiently and precisely measured in Drosophila, and that the DGRP strains show remarkable variation in DOE. A genome-wide analysis suggests that some well-known developmental genes are potentially associated with DOE. Further functional assays, or transcriptomic analysis of embryos from the DGRP, can validate the role of our candidates in early developmental processes. PMID- 27717306 TI - Close ecological relationship among species facilitated horizontal transfer of retrotransposons. AB - BACKGROUND: Horizontal transfer (HT) of genetic materials is increasingly being found in both animals and plants and mainly concerns transposable elements (TEs). Many crustaceans have big genome sizes and are thus likely to harbor high TE contents. Their habitat might offer them ample opportunities to exchange genetic materials with organisms that are ecologically close but taxonomically distant to them. RESULTS: In this study, we analyzed the transcriptome of Pacific white shrimp (Litopenaeus vannamei), an important economic crustacean, to explore traces of HT events. From a collection of newly assembled transcripts, we identified 395 high reliable TE transcripts, most of which were retrotransposon transcripts. One hundred fifty-seven of those transcripts showed highest similarity to sequences from non-arthropod organisms, including ray-finned fishes, mollusks and putative parasites. In total, 16 already known L. vannamei TE families are likely to be involved in horizontal transfer events. Phylogenetic analyses of 10 L. vannamei TE families and their homologues (protein sequences) revealed that L. vannamei TE families were generally more close to sequences from aquatic species. Furthermore, TEs from other aquatic species also tend to group together, although they are often distantly related in taxonomy. Sequences from parasites and microorganisms were also widely present, indicating their possible important roles in HT events. Expression profile analyses of transcripts in two NCBI BioProjects revealed that transcripts involved in HT events are likely to play important roles in antiviral immunity. More specifically, those transcripts might act as inhibitors of antiviral immunity. CONCLUSIONS: Close ecological relationship, especially predation, might greatly facilitate HT events among aquatic species. This could be achieved through exchange of parasites and microorganisms, or through direct DNA flow. The occurrence of HT events may be largely incidental, but the effects could be beneficial for recipients. PMID- 27717307 TI - Why do different oceanic archipelagos harbour contrasting levels of species diversity? The macaronesian endemic genus Pericallis (Asteraceae) provides insight into explaining the 'Azores diversity Enigma'. AB - BACKGROUND: Oceanic archipelagos typically harbour extensive radiations of flowering plants and a high proportion of endemics, many of which are restricted to a single island (Single Island Endemics; SIEs). The Azores represents an anomaly as overall levels of endemism are low; there are few SIEs and few documented cases of intra-archipelago radiations. The distinctiveness of the flora was first recognized by Darwin and has been referred to as the 'Azores Diversity Enigma' (ADE). Diversity patterns in the Macaronesian endemic genus Pericallis (Asteraceae) exemplify the ADE. In this study we used morphometric, Amplified Length Polymorphisms, and bioclimatic data for herbaceous Pericallis lineages endemic to the Azores and the Canaries, to test two key hypotheses proposed to explain the ADE: i) that it is a taxonomic artefact or Linnean shortfall, ie. the under description of taxa in the Azores or the over-splitting of taxa in the Canaries and (ii) that it reflects the greater ecological homogeneity of the Azores, which results in limited opportunity for ecological diversification compared to the Canaries. RESULTS: In both the Azores and the Canaries, morphological patterns were generally consistent with current taxonomic classifications. However, the AFLP data showed no genetic differentiation between the two currently recognized Azorean subspecies that are ecologically differentiated. Instead, genetic diversity in the Azores was structured geographically across the archipelago. In contrast, in the Canaries genetic differentiation was mostly consistent with morphology and current taxonomic treatments. Both Azorean and Canarian lineages exhibited ecological differentiation between currently recognized taxa. CONCLUSIONS: Neither a Linnean shortfall nor the perceived ecological homogeneity of the Azores fully explained the ADE-like pattern observed in Pericallis. Whilst variation in genetic data and morphological data in the Canaries were largely congruent, this was not the case in the Azores, where genetic patterns reflected inter-island geographical isolation, and morphology reflected intra-island bioclimatic variation. The combined effects of differences in (i) the extent of geographical isolation, (ii) population sizes and (iii) geographical occupancy of bioclimatic niche space, coupled with the morphological plasticity of Pericallis, may all have contributed to generating the contrasting patterns observed in the archipelagos. PMID- 27717308 TI - The effect of dietary restriction on reproduction: a meta-analytic perspective. AB - BACKGROUND: Dietary restriction (DR), a reduction in the amount of food or particular nutrients eaten, is the most consistent environmental manipulation to extend lifespan and protect against age related diseases. Current evolutionary theory explains this effect as a shift in the resolution of the trade-off between lifespan and reproduction. However, recent studies have questioned the role of reproduction in mediating the effect of DR on longevity and no study has quantitatively investigated the effect of DR on reproduction across species. RESULTS: Here we report a comprehensive comparative meta-analysis of the effect of DR on reproduction. In general, DR reduced reproduction across taxa, but several factors moderated this effect. The effect of DR on reproduction was greater in well-studied model species (yeast, nematode worms, fruit flies and rodents) than non-model species. This mirrors recent results for longevity and, for reproduction, seems to result from a faster rate of decline with decreasing resources in model species. Our results also suggested that not all reproductive traits are affected equally by DR. High and moderate cost reproductive traits suffered a significant reduction with DR, but low cost traits, such as ejaculate production, did not. Although the effect of DR on reproduction was stronger in females than males, this sex difference reduced to near zero when accounting for other co-factors such as the costliness of the reproductive trait. Thus, sex differences in the effect of DR on longevity may be due to a failure to expose males to as complete a range of the costs of reproduction as females. CONCLUSIONS: We suggest that to better understand the generality of the effect of DR, future studies should attempt to address the cause of the apparent model species bias and ensure that individuals are exposed to as many of the costs of reproduction as possible. Furthermore, our meta-analytic approach reveals a general shortage of DR studies that record reproduction, particularly in males, as well as a lack of direct side-by-side comparisons of the effect of DR on males and females. PMID- 27717309 TI - RStrucFam: a web server to associate structure and cognate RNA for RNA-binding proteins from sequence information. AB - BACKGROUND: RNA-binding proteins (RBPs) interact with their cognate RNA(s) to form large biomolecular assemblies. They are versatile in their functionality and are involved in a myriad of processes inside the cell. RBPs with similar structural features and common biological functions are grouped together into families and superfamilies. It will be useful to obtain an early understanding and association of RNA-binding property of sequences of gene products. Here, we report a web server, RStrucFam, to predict the structure, type of cognate RNA(s) and function(s) of proteins, where possible, from mere sequence information. RESULTS: The web server employs Hidden Markov Model scan (hmmscan) to enable association to a back-end database of structural and sequence families. The database (HMMRBP) comprises of 437 HMMs of RBP families of known structure that have been generated using structure-based sequence alignments and 746 sequence centric RBP family HMMs. The input protein sequence is associated with structural or sequence domain families, if structure or sequence signatures exist. In case of association of the protein with a family of known structures, output features like, multiple structure-based sequence alignment (MSSA) of the query with all others members of that family is provided. Further, cognate RNA partner(s) for that protein, Gene Ontology (GO) annotations, if any and a homology model of the protein can be obtained. The users can also browse through the database for details pertaining to each family, protein or RNA and their related information based on keyword search or RNA motif search. CONCLUSIONS: RStrucFam is a web server that exploits structurally conserved features of RBPs, derived from known family members and imprinted in mathematical profiles, to predict putative RBPs from sequence information. Proteins that fail to associate with such structure centric families are further queried against the sequence-centric RBP family HMMs in the HMMRBP database. Further, all other essential information pertaining to an RBP, like overall function annotations, are provided. The web server can be accessed at the following link: http://caps.ncbs.res.in/rstrucfam . PMID- 27717310 TI - Faecal calprotectin: factors affecting levels and its potential role as a surrogate marker for risk of development of Crohn's Disease. AB - BACKGROUND: Faecal calprotectin (FC) is one of the most widely used non-invasive tests for the diagnosis and assessment of Crohn's disease (CD) activity. Despite this, factors other than disease activity which affect levels have not been extensively reviewed. This is of importance when using FC in the diagnostic setting but also may be of utility in studying the aetiology of disease. OBJECTIVES: Our review outlines environmental risk factors that affect FC levels influencing diagnostic accuracy and how these may be associated with risk of developing CD. FC as a surrogate marker could be used to validate risk factors established in case control studies where prospective studies are not feasible. Proof of this concept is provided by our identification of obesity as being associated with elevated FC, our subsequent confirmation of obesity as risk factor for CD and the subsequent verification in prospective studies, as well as associations of lack of physical activity and dietary fibre intake with elevated FC levels and their subsequent confirmation as risk factors in prospective studies. CONCLUSION: We believe that FC is likely to prove a useful surrogate marker for risk of developing CD. This review has given a theoretical basis for considering the epidemiological determinants of CD which to date has been missing. PMID- 27717311 TI - Formation of diploid and triploid hybrid groupers (hybridization of Epinephelus coioides ? * Epinephelus lanceolatus ?) and their 5S gene analysis. AB - BACKGROUND: Interspecies hybridization is widely used to achieve heterosis or hybrid vigor, which has been observed and harnessed by breeders for centuries. Natural allopolyploid hybrids generally exhibit more superior heterosis than both the diploid progenies and their parental species. However, polyploid formation processes have been long ignored, the genetic basis of heterosis in polyploids remains elusive. RESULTS: In the present study, triploid hybrids had been demonstrated to contain two sets of chromosomes from mother species and one set from father species. Cellular polyploidization process in the embryos had been traced. The triploid hybrids might be formed by failure formation of the second polarized genome during the second meiosis stage. Four spindle centers were observed in anaphase stage of the first cell division. Three spindle centers were observed in side of cell plate after the first cell division. The 5S rDNA genes of four types of groupers were cloned and analyzed. The diploid and triploid hybrids had been proved to contain the tandem chimera structures which were recombined by maternal and paternal monomer units. The results indicated that genome re-fusion had occurred in the hybrid progenies. To further elucidate the genetic patterns of diploid and triploid hybrids, fluorescence chromosome location had been carried out, maternal 5S gene (M-386) were used as the probe. The triploid hybrids contained fewer fluorescence loci numbers than the maternal species. The results indicated that participation of paternal 5S gene in the triploid hybrid genome had degraded the match rates of M-386 probe. CONCLUSIONS: Our study is the first to investigate the cellular formation processes of natural allopolyploids in hybrid fish, the cellular polyploidization process may be caused by failure formation of the second polarized genome during the meiosis, and our results will provide the molecular basis of hybrid vigor in interspecies hybridization. PMID- 27717313 TI - Heterozygous p.S811F RET gene mutation associated with renal agenesis, oligomeganephronia and total colonic aganglionosis: a case report. AB - BACKGROUND: Several shared common gene networks participate in development of interstinal ganglia and also nephron formation; the glial cell line-derived neurotrophic factor/Ret/glial cell line-derived neurotrophic factor receptor gene network is particularly important. CASE PRESENTATION: We encountered a patient with total colonic aganglionosis as well as right renal agenesis and oligomeganephronia. Gene analysis in this patient disclosed a heterozygous p.S811F mutation was in Ret gene exon 14, resulting in a substitution of phenylalanine for serine. The large side chain of phenylalanine obstructed the opening of the hydrophobic pocket of the Ret molecule causing interference with its interaction with adenosine triphosphate and consequent marked reduction in its enzyme activity. This could account for our patient's severe intestinal disease and renal dysplasia. We know of no previous reports of concomitant Hirschsprung's disease and oligomeganephronia. CONCLUSIONS: The patient's overall illness could be considered a novel Ret gene mutation syndrome. PMID- 27717312 TI - Members of WRKY Group III transcription factors are important in TYLCV defense signaling pathway in tomato (Solanum lycopersicum). AB - BACKGROUND: Transmitted by the whitefly Bemisia tabaci, tomato yellow leaf curly virus (TYLCV) has posed serious threats to plant growth and development. Plant innate immune systems against various threats involve WRKY Group III transcription factors (TFs). This group participates as a major component of biological processes in plants. RESULTS: In this study, 6 WRKY Group III TFs (SolyWRKY41, SolyWRKY42, SolyWRKY53, SolyWRKY54, SolyWRKY80, and SolyWRKY81) were identified, and these TFs responded to TYLCV infection. Subcellular localization analysis indicated that SolyWRKY41 and SolyWRKY54 were nuclear proteins in vivo. Many elements, including W-box, were found in the promoter region of Group III TFs. Interaction network analysis revealed that Group III TFs could interact with other proteins, such as mitogen-activated protein kinase 5 (MAPK) and isochorismate synthase (ICS), to respond to biotic and abiotic stresses. Positive and negative expression patterns showed that WRKY Group III genes could also respond to TYLCV infection in tomato. The DNA content of TYLCV resistant lines after SolyWRKY41 and SolyWRKY54 were subjected to virus-induced gene silencing (VIGS) was lower than that of the control lines. CONCLUSIONS: In the present study, 6 WRKY Group III TFs in tomato were identified to respond to TYLCV infection. Quantitative real-time-polymerase chain reaction (RT-qPCR) and VIGS analyses demonstrated that Group III genes served as positive and negative regulators in tomato-TYLCV interaction. WRKY Group III TFs could interact with other proteins by binding to cis elements existing in the promoter regions of other genes to regulate pathogen-related gene expression. PMID- 27717314 TI - High frequency of pre-existing neutralizing antibody responses in patients with dengue during an outbreak in Central Brazil. AB - BACKGROUND: This study aims to identify dengue neutralizing antibody response in patients with dengue from a well-characterized cohort during an outbreak in central Brazil, 2012-2013. METHODS: We analyzed paired samples from 40 patients with severe dengue and 20 patients with dengue. Eligibility criteria were: IgM, NS1Ag and/or RT-PCR positivity and positive IgG result. Plaque reduction neutralization test (PRNT50) from DENV-1 to DENV-4 was performed to identify serotype-specific NAbs response. An infecting serotype was defined as >=4-fold increase in DENV NAbs in paired samples. Monotypic response was classified as PRNT50 >= 1/20 to only one DENV serotype, and multitypic response was considered to be PRNT50 >= 1/20 to two or more serotypes simultaneously. RESULTS: Patients were mainly adults. Virological dengue infection was confirmed by RT-PCR: DENV 4(n = 14) and DENV-1(n = 10). Forty-four out of 60(73.3 %) patients had NAbs to DENV-4, DENV-1(68.3 %), DENV-2(68.3 %) and DENV-3(61.6 %) respectively. Fifteen percent of the cases presented monotypic response, whereas 85 % had multitypic response. DENV-4 infected-patients presented the greatest difference in PRNT50 titers compared with other serotypes. Pre-existing DENV NAbs was not correlated with disease severity. This was the first time that DENV-4 was implicated in an epidemic in the region. CONCLUSION: Our data indicates high exposure of multiple DENV serotypes in all age groups in the pre-dengue vaccine era and also previous to Zika virus introduction in Brazil. PMID- 27717315 TI - A phase I study of nedaplatin, pemetrexed and thoracic intensity-modulated radiotherapy for inoperable stage III lung adenocarcinoma. AB - BACKGROUND: Concurrent chemotherapy and radiation is the standard treatment for unresectable stage III Lung adenocarcinoma. However, no optimal concurrent chemotherapeutic regimen has been described. This study aimed to assess concurrent pemetrexed, nedaplatin and thoracic intensity-modulated radiotherapy followed by consolidation pemetrexed/nedaplatin for unresectable Stage IIIA/B lung adenocarcinoma. METHODS: Patients with unresectable stage III lung adenocarcinoma received thoracic intensity-modulated radiotherapy at 60-64 Gy in 30-32 fractions, concurrently with two cycles of 500 mg/m2 pemetrexed, with nedaplatin doses escalating from 60 mg/m2 (level 1) to 70 mg/m2 (level 2) and 80 mg/m2 (level 3). Consolidation consisted of three pemetrexed/nedaplatin (500 mg/m2, 60 mg/m2) cycles every 3 weeks after concurrent therapy. The primary objective of the safety was to determine the maximum-tolerated dose (MTD). The secondary endpoints included response rate, PFS and OS. RESULTS: Fifteen patients were enrolled, including 3, 6 and 6 individuals in the first, second, and third dose levels, respectively. Three cases of dose-limiting toxicities (grade 3 hepatitis, pneumonitis, and grade 4 thrombocytopenia), including one and two patients at levels 2 and 3, respectively, were observed and resulted in discontinued/delayed treatment. Response rates were 86.7 % (95 % confidence interval [CI], 64.2-97.8 %) and 64.3 % (95 % CI, 38.3-85.4 %) at chemoradiation and treatment completions, respectively. Median OS was 30.0 months (95 % CI, 16.4 43.6 months); 2-year OS was 44.0 % (95 % CI, 18.7-69.2 %). Median PFS was 12.0 months (95 % CI, 6.9-17.0 months), and the 2-year PFS 27.0 % (95 % CI, 4.7-49.3 %). CONCLUSIONS: Full dose 500 mg/m2 of pemetrexed and nedaplatin 70 mg/m2 could be used safely with thoracic intensity-modulated radiotherapy for inoperable stage III lung adenocarcinoma. Further evaluation of stage III lung adenocarcinoma management is warranted.

PMID- 27717316 TI - A rare c.183_187dupCTCAC mutation of the acetylcholine receptor CHRNE gene in a South Asian female with congenital myasthenic syndrome: a case report. AB - BACKGROUND: Congenital myasthenic syndromes (CMSs) occur as a result of genetic mutations that cause aberrations in structure and/or function of proteins involved in neuromuscular transmission. Acetylcholine receptor epsilon (epsilon) subunit (CHRNE) gene mutations account for about 30-50 % of genetically diagnosed cases. We report a rare CHRNE gene mutation in a South Asian female with CMS. CASE PRESENTATION: A 17-year-old Maldivian female presented with bilateral partial ptosis, fatigable proximal muscle weakness and slurring of speech noted since the age of 2 years. She could not run, had difficulty negotiating stairs and rising from a seated position, and fatigues when speaking at length. Her birth and past medical histories were otherwise unremarkable. There is no parental consanguinity or family history of muscle disorders. On examination, she had a BMI of 18 kg/m2, bilateral fatigable partial ptosis, complete external ophthalmoplegia and fatigable proximal muscle weakness (MRC grade 4/5). Apart from spinal scoliosis the rest of the examination was normal. Haematological and biochemical investigations including serum lactate level and thyroid functions were normal. Acetylcholine receptor antibodies and muscle specific kinase antibodies were not detected in serum. Repetitive nerve stimulation showed marked decrement (>30 %) in nerve-muscle pairs in the face and forearm. Her DNA sequencing revealed a c.183-187dupCTCAC mutation in CHRNE. She remained functionally independent on pyridostigmine treatment. CONCLUSIONS: This case describes a rare mutation of the CHRNE gene in CMS and highlights the relevance of genetic diagnosis in CMS. It further adds to map the occurrence of such mutations in Asian populations. PMID- 27717317 TI - The feasibility and diagnostic accuracy by multiple cardiac biomarkers in emergency chest pain patients: a clinical analysis to compare 290 suspected acute coronary syndrome cases stratified by age and gender in Taiwan. AB - BACKGROUND: Accurate diagnosis of acute coronary syndrome (ACS) in a timely fashion is challenging in the elderly population, especially elderly women, who usually exhibit atypical clinical symptoms. A multiple cardiac biomarker (MCB) based approach has been shown to improve diagnostic efficacy of ACS. However, data in various age groups and sex differences remain largely unexplored. METHODS: Point-of-care testing (POCT) was performed on 290 patients (aged >=18 years) who were admitted to the emergency department (ED) with symptoms of acute chest pain under suspicion of acute coronary syndrome (ACS). The MCB approach in current work assessed four cardiac biomarkers: myoglobin, troponin I, creatine kinase-myocardial band isoenzyme fraction (CK-MB), and brain natriuretic peptide (BNP). RESULTS: Overall, the MCB approach demonstrated considerably higher sensitivity for elderly patients than for younger patients in identifying ACS (80.0 % [64.1-90.0] vs. 52.6 % [37.3-67.5] for >=65 years and <65 years groups), with younger population showed greater specificity (44.1 % [35.3-53.4] vs. 84.9 % [76.9-90.5] for >=65 years and <65 years groups, respectively). The highest sensitivity achieved for elderly women who reported chest pain was 87.5 % [95 % CI: 64-96.5]). In general, the sensitivity of this approach was higher for female patients than for male patients (80 % [58.4-91.9] vs. 61 % [47.8-73.0]). CONCLUSIONS: The MCB approach can provide a quick and accurate clinical diagnosis in elderly and female patients, both of whom have traditionally proven to be challenging to diagnose from suspected acute coronary syndrome. PMID- 27717318 TI - Recombinant domains III of Tick-Borne Encephalitis Virus envelope protein in combination with dextran and CpGs induce immune response and partial protectiveness against TBE virus infection in mice. AB - BACKGROUND: E protein of tick-borne encephalitis virus (TBEV) and other flaviviruses is located on the surface of the viral particle. Domain III of this protein seems to be a promising component of subunit vaccines for prophylaxis of TBE and kits for diagnostics of TBEV. METHODS: Three variants of recombinant TBEV E protein domain III of European, Siberian and Far Eastern subtypes fused with dextran-binding domain of Leuconostoc citreum KM20 were expressed in E. coli and purified. The native structure of domain III was confirmed by ELISA antibody kit and sera of patients with tick-borne encephalitis. Immunogenic and protective properties of the preparation comprising these recombinant proteins immobilized on a dextran carrier with CpG oligonucleotides as an adjuvant were investigated on the mice model. RESULTS: All 3 variants of recombinant proteins immobilized on dextran demonstrate specific interaction with antibodies from the sera of TBE patients. Thus, constructed recombinant proteins seem to be promising for TBE diagnostics. The formulation comprising the 3 variants of recombinant antigens immobilized on dextran and CpG oligonucleotides, induces the production of neutralizing antibodies against TBEV of different subtypes and demonstrates partial protectivity against TBEV infection. CONCLUSIONS: Studied proteins interact with the sera of TBE patients, and, in combination with dextran and CPGs, demonstrate immunogenicity and limited protectivity on mice compared with reference "Tick-E-Vac" vaccine. PMID- 27717319 TI - Does acupuncture have a role in the treatment of threatened miscarriage? Findings from a feasibility randomised trial and semi-structured participant interviews. AB - BACKGROUND: Threatened miscarriage is a common complication of early pregnancy increasing the risk of miscarriage or premature labour. Currently there is limited evidence to recommend any biomedical pharmacological or self-care management, resulting in a 'watchful waiting' approach. The objective of this study was to examine the feasibility of offering acupuncture as a therapeutic treatment for women presenting with threatened miscarriage. METHODS: A mixed methods study involving a randomised controlled trial and semi structured interviews. A pragmatic acupuncture protocol including medical self-care advice was compared to an active control receiving touch intervention and medical self care advice. Descriptive statistics were used to examine the demographic and baseline characteristics. Endpoints were analysed between groups using a mean t test and chi-square tests with P < 0.05 considered statistically significant. Dichotomous data was expressed as Risk Ratio with 95 % confidence intervals. Eleven participants were purposively interviewed about their experiences on exiting the trial with interviews analysed using thematic analysis. RESULTS: Forty women were successfully randomised. For women receiving acupuncture there was a statically significant reduction with threatened miscarriage symptoms including bleeding, cramping and back pain compared with the control (p = 0.04). Thematic analysis revealed women were dissatisfied with the medical support and advice received. An overarching theme emerged from the data of 'finding something you can do.' This encompassed the themes: 'they said there was nothing they could do,' 'feeling the benefits' and 'managing while marking time.' CONCLUSION: Acupuncture was a feasible intervention and reduced threatened miscarriage symptoms when compared to a touch intervention. Further research is required to further explore acupuncture use for this common complication and whether it can reduce the incidence of miscarriage.

AB - BACKGROUND: In children with cerebral palsy (CP), stiffness, caused by contractile and non-contractile structures, can influence motor performance. This study sought to determine whether the nerve mobility had a relevant impact on motor performance in children with CP. We hypothesized that a positive Straight Leg Raise (SLR) test, as well as smaller SLR hip angle, would relate to lower leg muscle strength, reduced motor capacity and less motor performance in children with CP. METHODS: We applied a cross-sectional analysis on data including SLR, leg muscle strength, Gross Motor Function Measure (GMFM-66) and number of activity counts during daily life from thirty children with CP (6-18 years). We performed receiver operating characteristics and correlation analyses. RESULTS: Positive SLR test could distinguish well between children with low versus high muscle strength and GMFM-66 scores. The SLR hip angle correlated significant with the level of disability and with muscle strength. The correlation with the GMFM 66 and the activity counts was fair. CONCLUSION: This study suggests that neural restriction of SLR is higher on functional and activity outcome than the measured SLR hip range of motion. Further studies should investigate weather improving nerve mobility can lead to an amelioration of function in children with CP. PMID- 27717321 TI - Mechanisms and direction of allocation bias in randomised clinical trials. AB - BACKGROUND: Selective allocation of patients into the compared groups of a randomised trial may cause allocation bias, but the mechanisms behind the bias and its directionality are incompletely understood. We therefore analysed the mechanisms and directionality of allocation bias in randomised clinical trials. METHODS: Two systematic reviews and a theoretical analysis. We conducted one systematic review of empirical studies of motives/methods for deciphering patient allocation sequences; and another review of methods publications commenting on allocation bias. We theoretically analysed the mechanisms of allocation bias and hypothesised which main factors predicts its direction. RESULTS: Three empirical studies addressed motives/methods for deciphering allocation sequences. Main motives included ensuring best care for patients and ensuring best outcome for the trial. Main methods included various manipulations with randomisation envelopes. Out of 57 methods publications 11 (19 %) mentioned explicitly that allocation bias can go in either direction. We hypothesised that the direction of allocation bias is mainly decided by the interaction between the patient allocators' motives and treatment preference. CONCLUSION: Inadequate allocation concealment may exaggerate treatment effects in some trials while underestimate effects in others. Our hypothesis provides a theoretical overview of the main factors responsible for the direction of allocation bias. PMID- 27717322 TI - Ergocalciferol treatment does Not improve erythropoietin utilization and hospitalization rate in hemodialysis patients. AB - BACKGROUND: Vitamin D (25-hydroxyvitamin D; 25[OH]D) deficiency (VDD) is highly prevalent in chronic kidney disease. The aim of this study was to evaluate the effect of oral ergocalciferol supplementation on requirement of erythropoietin (EPO) and active vitamin D analogues, and hospitalization rate in maintenance hemodialysis (HD) patients. METHODS: This retrospective cohort study included 186 patients who were on HD for 3 months and had 25(OH)D levels < 30 ng/ml. Over 1 year period, 107 patients were supplemented with protocol-based ergocalciferol (D2 group) and 79 were not (control). Parameters of erythropoiesis and bone mineral metabolism, and monthly doses of EPO and paricalcitol were assessed at 6- and 12- months of ergocalciferol supplementation. Total hospitalizations were recorded for the same year. RESULTS: Baseline characteristics were similar across two arms except higher serum ferritin, transferrin saturation and prevalence of stroke in D2 and higher coronary artery disease in control group with overall mean +/- SD 25(OH)D level of 16.8 +/- 7 ng/ml. At 12 months, 25(OH)D levels increased significantly in D2 group compared to control (30.5 +/- 11.7 vs. 14.2 +/- 9.3 ng/ml; p < 0.001). The EPO dose remained same with no difference in hemoglobin values between the two groups during the intervention period. On multivariate regression which included above variables there was no effect of ergocalciferol treatment on EPO dose (p = ns). Hospitalization rate was similar in two arms; however, ergocalciferol treatment inversely associated with paricalcitol dose (beta +/- SE = -10.4 +/- 2.8; p < 0.001). CONCLUSIONS: One-year of ergocalciferol supplementation was not associated with reduction in EPO requirement or hospitalization rate in HD patients with VDD. Further studies are warranted to determine definitive role of nutritional vitamin D in these patients. PMID- 27717323 TI - Outcome of low dose cyclophosphamide for induction phase treatment of lupus nephritis, a single center study. AB - BACKGROUND: The current standard for induction phase treatment of lupus nephritis is steroid combined with mycophenolate mofetil or pulse intravenous cyclophosphamide (IVC). The lowest dose of IVC recommended for induction therapy is that used in the Euro-Lupus Trial. It is not known whether same cumulative dose of IVC would be effective when given over six months. METHODS: We carried out a prospective, observational study on 41 patients of biopsy-proven lupus nephritis (class III, IV, V or mixed). For induction, patients received six pulses of monthly IVC (500 mg each), along with steroid. Patients were followed up monthly until one month beyond completion of the sixth pulse. The outcomes assessed were complete remission (proteinuria < 200 mg/day or urine albumin nil with serum albumin >35 gm/L, stable estimated glomerular filtration rate (eGFR) if normal at baseline or increase in eGFR by 25 % if abnormal at baseline and normal urinary sediment), response (complete or partial remissions), complications of therapy and death. RESULTS: Twenty two patients (53.7 %) had class IV nephritis. Eighteen patients (43.9 %) achieved complete remission, 16 (39.0 %) achieved partial remission, yielding an overall response rate of 82.9 %. Nephrotic range proteinuria (UTP >= 3 g/day) and severe hypoalbuminemia (serum albumin < 20 g/L) at baseline influenced remission (p <0.05). Infection, seen in 12 patients (29.3 %), was the most common complication. Four deaths (9.6 %) were observed, all due to infection. CONCLUSIONS: For induction phase treatment, Nepalese patients with lupus nephritis responded favorably to steroid and low dose IVC of 3 grams given as six monthly pulses. PMID- 27717324 TI - The prevalence of stroke and depression and factors associated with depression in elderly people with and without stroke. AB - BACKGROUND: Few studies have investigated factors associated with depression among elderly people with and without stroke concurrently, using identical settings, procedures and study variables. The aim was to investigate the prevalence of stroke and depression and to compare the factors associated with depression in people with and without stroke. METHODS: A postal mail survey was sent to 65-, 70-, 75- and 80-year-olds in northern Sweden and Finland in 2010 (n = 6098). Stroke was defined as answering "yes" to the question "Have you had a stroke?" Depression was defined as answering "yes" to the question "Are you depressed?" or having a Geriatric Depression Scale-4 score >=2. Dependence in personal activities of daily living was defined as not showering without human assistance. Associations were tested with log-binomial regression. RESULTS: The overall stroke prevalence was 7.0 +/- 0.3 % and increased from 4.7 +/- 0.4 % among 65-year-olds to 11.6 +/- 1.0 % among 80-year-olds (p < 0.001). The overall depression prevalence was 12.8 +/- 0.4 % and increased from 11.0 +/- 0.6 % among 65-year-olds to 18.1 +/- 1.2 % among 80-year-olds (p < 0.001). Depression was more common among people with stroke (Prevalence Ratio 1.77, 95 % Confidence Interval 1.48-2.12). In the non-stroke group, depression was independently associated with diabetes, dependence in instrumental activities of daily living, living alone, not having someone to talk to, poor finances, pain problems and having a life crisis in the preceding year. In the group with stroke, depression was independently associated with dependence in personal activities of daily living and having a life crisis the preceding year. CONCLUSIONS: Depression in people without stroke appeared to be independently associated with a broader range of external factors than depression in people with stroke. PMID- 27717325 TI - Ciprofloxacin triggered glutamate production by Corynebacterium glutamicum. AB - BACKGROUND: Corynebacterium glutamicum is a well-studied bacterium which naturally overproduces glutamate when induced by an elicitor. Glutamate production is accompanied by decreased 2-oxoglutatate dehydrogenase activity. Elicitors of glutamate production by C. glutamicum analyzed to molecular detail target the cell envelope. RESULTS: Ciprofloxacin, an inhibitor of bacterial DNA gyrase and topoisomerase IV, was shown to inhibit growth of C. glutamicum wild type with concomitant excretion of glutamate. Enzyme assays showed that 2 oxoglutarate dehydrogenase activity was decreased due to ciprofloxacin addition. Transcriptome analysis revealed that this inhibitor of DNA gyrase increased RNA levels of genes involved in DNA synthesis, repair and modification. Glutamate production triggered by ciprofloxacin led to glutamate titers of up to 37 +/- 1 mM and a substrate specific glutamate yield of 0.13 g/g. Even in the absence of the putative glutamate exporter gene yggB, ciprofloxacin effectively triggered glutamate production. When C. glutamicum wild type was cultivated under nitrogen limiting conditions, 2-oxoglutarate rather than glutamate was produced as consequence of exposure to ciprofloxacin. Recombinant C. glutamicum strains overproducing lysine, arginine, ornithine, and putrescine, respectively, secreted glutamate instead of the desired amino acid when exposed to ciprofloxacin. CONCLUSIONS: Ciprofloxacin induced DNA synthesis and repair genes, reduced 2 oxoglutarate dehydrogenase activity and elicited glutamate production by C. glutamicum. Production of 2-oxoglutarate could be triggered by ciprofloxacin under nitrogen-limiting conditions. PMID- 27717326 TI - Fall risk as a function of time after admission to sub-acute geriatric hospital units. AB - BACKGROUND: There is evidence about time-dependent fracture rates in different settings and situations. Lacking are data about underlying time-dependent fall risk patterns. The objective of the study was to analyse fall rates as a function of time after admission to sub-acute hospital units and to evaluate the time dependent impact of clinical factors at baseline on fall risk. METHODS: This retrospective cohort study used data of 5,255 patients admitted to sub-acute units in a geriatric rehabilitation clinic in Germany between 2010 and 2014. Falls, personal characteristics and functional status at admission were extracted from the hospital information system. The rehabilitation stay was divided in 3 day time-intervals. The fall rate was calculated for each time-interval in all patients combined and in subgroups of patients. To analyse the influence of covariates on fall risk over time multivariate negative binomial regression models were applied for each of 5 time-intervals. RESULTS: The overall fall rate was 10.2 falls/1,000 person-days with highest fall risks during the first week and decreasing risks within the following weeks. A particularly pronounced risk pattern with high fall risks during the first days and decreasing risks thereafter was observed in men, disoriented people, and people with a low functional status or impaired cognition. In disoriented patients, for example, the fall rate decreased from 24.6 falls/1,000 person-days in day 2-4 to about 13 falls/1,000 person-days 2 weeks later. The incidence rate ratio of baseline characteristics changed also over time. CONCLUSIONS: Fall risk differs considerably over time during sub-acute hospitalisation. The strongest association between time and fall risk was observed in functionally limited patients with high risks during the first days after admission and declining risks thereafter. This should be considered in the planning and application of fall prevention measures. PMID- 27717327 TI - Does conservation account for splicing patterns? AB - BACKGROUND: Alternative mRNA splicing is critical to proteomic diversity and tissue and species differentiation. Exclusion of cassette exons, also called exon skipping, is the most common type of alternative splicing in mammals. RESULTS: We present a computational model that predicts absolute (though not tissue differential) percent-spliced-in of cassette exons more accurately than previous models, despite not using any 'hand-crafted' biological features such as motif counts. We achieve nearly identical performance using only the conservation score (mammalian phastCons) of each splice junction normalized by average conservation over 100 bp of the corresponding flanking intron, demonstrating that conservation is an unexpectedly powerful indicator of alternative splicing patterns. Using this method, we provide evidence that intronic splicing regulation occurs predominantly within 100 bp of the alternative splice sites and that conserved elements in this region are, as expected, functioning as splicing regulators. We show that among conserved cassette exons, increased conservation of flanking introns is associated with reduced inclusion. We also propose a new definition of intronic splicing regulatory elements (ISREs) that is independent of conservation, and show that most ISREs do not match known binding sites or splicing factors despite being predictive of percent-spliced-in. CONCLUSIONS: These findings suggest that one mechanism for the evolutionary transition from constitutive to alternative splicing is the emergence of cis-acting splicing inhibitors. The association of our ISREs with differences in splicing suggests the existence of novel RNA-binding proteins and/or novel splicing roles for known RNA-binding proteins. PMID- 27717329 TI - QuantiFERON conversion following tuberculin administration is common in HIV infection and relates to baseline response. AB - BACKGROUND: HIV-1 infection impairs tuberculosis (TB) specific immune responses affecting the diagnosis of latent TB. We aimed to (1) determine the proportion of HIV-1-infected adults with a negative QuantiFERON(r)-TB Gold in-tube (QFT-GIT) and Tuberculin skin testing (TST) that convert to QFT-GIT positive following TST, and (2) evaluate the relationship between conversion and baseline QFT-GIT results. METHODS: HIV-1 infected adults being screened for a TB vaccine study in South Africa underwent QFT-GIT followed by TST. As per protocol, QFT-GIT was repeated if randomization was delayed allowing for evaluation of TST boosting in a proportion of participants. RESULTS: Of the 22 HIV-1 infected, TST and QFT-GIT negative adults (median CD4 477/mm3 IQR 439-621) who had QFT-GIT repeated after median 62 days (IQR 49-70), 40.9 % (95 % CI 18.6-63.2 %) converted. Converters had a significantly greater increase in the background subtracted TB antigen response (TBAg-Nil - all units IU/mL) following TST, 0.82 (IQR 0.39-1.28) vs 0.03 (IQR -0.05-0.06), p = 0.0001. Those who converted also had a significantly higher baseline TBAg-Nil 0.21(IQR 0.17-0.26) vs 0.02(IQR 0.01-0.07), p = 0.002. Converters did not differ with regard to CD4 count or ART status. ROC analysis showed a baseline cut off of 0.15 correctly classified 86.4 % of converters with 88.9 % sensitivity. CONCLUSIONS: Our findings support the possibility that there are 2 distinct groups in an HIV-1 infected population with negative QFT-GIT and TST; a true negative group and a group showing evidence of a weak Mtb specific immune response that boosts significantly following TST resulting in conversion of the test result that may represent false negatives. Further evaluation of whether a lower cut off may improve sensitivity of QFT-GIT in this population is warranted. PMID- 27717328 TI - Nationwide distribution of varicella-zoster virus clades in China. AB - BACKGROUND: In 2010, a universal nomenclature for varicella-zoster virus (VZV) clades was established, which is very useful in the monitoring of viral evolution, recombination, spread and genetic diversity. Currently, information about VZV clades has been disclosed worldwide, however, there are limited data regarding the characterization of circulating VZV clades in China, even where varicella remains widely epidemic. METHODS: From 2008 to 2012, clinical samples with varicella or zoster were collected in General Hospital in eight provinces and analyzed by PCR, restriction endonuclease digestion and sequencing. The viral clades were determined by analysis of five single nucleotide polymorphisms (SNPs) within the 447-bp fragment of open reading frame (ORF) 22, and the restriction fragment length polymorphisms (RFLPs) of ORF 38 (PstI), ORF 54 (BglI) and ORF 62 (SmaI) were evaluated to understand genetic diversity of VZV and determinate varicella vaccine adverse event (VVAE). RESULTS: Seventy-seven varicella and 11 zoster samples were identified as being positive for VZV. The five SNPs profile showed that the majority of VZV strains belonged to clade 2, but clade 5 and clade 4 strains were also found in Guangdong. The RFLPs analysis of the DNA fragments of ORF 38, 54 and 62 showed that 85 of these samples were characterized as PstI + BglI + SamI-, and the remaining three VZV strains from varicella patients were characterized as PstI-BglI + SamI+ which is the genetic profile of VVAEs. CONCLUSIONS: The study suggested that the predominant clade 2 VZVs had been continually circulating since at least the 1950s in China. Nearly all VZV strains except VVAEs possessed the genetic profile of PstI + BglI + Sam-. However, the other clades were also found to be co-circulating with clade 2, especially in the border regions. These results highlighted the need for the constant and broad use of virologic surveillance to provide an important genetic baseline for varicella control and vaccination programs in China. PMID- 27717331 TI - Characterization of eleven monosomic alien addition lines added from Gossypium anomalum to Gossypium hirsutum using improved GISH and SSR markers. AB - BACKGROUND: Gossypium anomalum (BB genome) possesses the desirable characteristics of drought tolerance, resistance to diseases and insect pests, and the potential for high quality fibers. However, it is difficult to transfer the genes associated with these desirable traits into cultivated cotton (G. hirsutum, AADD genome). Monosomic alien addition lines (MAALs) can be used as a bridge to transfer desired genes from wild species into G. hirsutum. In cotton, however, the high number and smaller size of the chromosomes has resulted in difficulties in discriminating chromosomes from wild species in cultivated cotton background, the development of cotton MAALs has lagged far behind many other crops. To date, no set of G. hirsutum-G. anomalum MAALs was reported. Here the amphiploid (AADDBB genome) derived from G. hirsutum * G. anomalum was used to generate a set of G. hirsutum-G. anomalum MAALs through a combination of consecutive backcrossing, genomic in situ hybridization (GISH), morphological survey and microsatellite marker identification. RESULTS: We improved the GISH technique used in our previous research by using a mixture of two probes from G. anomalum and G. herbaceum (AA genome). The results indicate that a ratio of 4:3 (G. anomalum : G. herbaceum) is the most suitable for discrimination of chromosomes from G. anomalum and the At-subgenome of G. hirsutum. Using this improved GISH technique, 108 MAAL individuals were isolated. Next, 170 G. hirsutum- and G. anomalum-specific codominant markers were obtained and employed for characterization of these MAAL individuals. Finally, eleven out of 13 MAALs were identified. Unfortunately, we were unable to isolate Chrs. 1Ba and 5Ba due to their very low incidences in backcrossing generation, as these remained in a condition of multiple additions. CONCLUSIONS: The characterized lines can be employed as bridges for the transfer of desired genes from G. anomalum into G. hirsutum, as well as for gene assignment, isolation of chromosome-specific probes, development of chromosome-specific "paints" for fluorochrome-labeled DNA fragments, physical mapping, and selective isolation and mapping of cDNAs/genes for a particular G. anomalum chromosome. PMID- 27717330 TI - Role of vitamin D3 combined to alginates in preventing acid and oxidative injury in cultured gastric epithelial cells. AB - BACKGROUND: Gastric diseases are a worldwide problem in modern society, as reported in the USA, in the range of 0.5-2 episodes/year/person and an incidence of 5-100 episodes/1000/week according to seasons and age. There is convincing evidence that oxidative stress is involved in the pathogenesis of acute gastric injury. Acid secreted from gastric parietal cells determines mucosal injuries which in turn cause inflammation and oxidative stress. Consequent inflammation produces free radicals by mitochondria thus causing lipid peroxidation, oxidative and acidic stress, which can lead to cell apoptosis. Vitamin D3, the active form of vitamin D, may counteract intracellular cell death and improve epithelial regeneration. METHODS: This study was planned to assess whether vitamin D3 is a protective factor against acid injury and oxidative stress in gastric epithelial cells. Primary epithelial cells and GTL-16 cells have been used to test the effects of Grisu(r) alone or in combination with vitamin D3 during oxidative stress or high acid exposition measuring cell viability, ROS production, cellular adhesion time along with apoptotic, autophagic and survival pathways. The combined effect of Grisu(r) and vitamin D3 was found more effective in counteracting the negative consequences of oxidative stress and acidity conditions than some other gastroprotective agents, such as Maalox(r) or Gaviscon(r). RESULTS: In case of oxidative stress or acidity condition the stimulation with Grisu(r) alone caused an improvement of cell viability and a reduction of ROS production on epithelial gastric cells. In addition, the adhesion time of the cells was improved. All these effects were increased by the presence of vitamin D3. Similar data were also observed in primary gastric epithelial cells confirming the results obtained in GTL-16 cells. CONCLUSIONS: These results suggest that Grisu(r) in combination with vitamin D3 may exert a gastroprotective effect to maintain or restore the integrity of gastric epithelium through an antioxidant pathway, inhibiting apoptosis and activating survival kinases. Moreover, the combination of Grisu(r) and vitamin D3 improves cell viability and decreases ROS production compared to other gastroprotective agents combined with vitamin D3. All these data were validated using primary cells isolated from gastric tissue.

PMID- 27717333 TI - A household-based survey of knowledge, attitudes and practices towards dengue fever among local urban communities in Taiz Governorate, Yemen. AB - BACKGROUND: Yemen has witnessed several dengue fever outbreaks coincident with the social unrest and war in the country. The aim of the present study was to describe the knowledge, attitudes and practices (KAPs) of at-risk urban populations residing in Taiz, southwest of Yemen. In addition, factors possibly associated with poor preventive practices were investigated. METHODS: A household based, cross-sectional survey was conducted in three urban districts encompassing 383 households. Data on the socio-demographic characteristics and KAPs of the participating household heads were collected using a pre-designed, structured questionnaire. The association of socio-demographic characteristics, knowledge and attitudes of the population with poor preventive practices against dengue fever was then analyzed using logistic regression. RESULTS: More than 90.0 % of respondent household heads had correct knowledge about fever, headache and joint pain as common signs and symptoms of dengue fever. Moreover, muscular pain and bleeding were perceived by more than 80.0 % of the respondents as being associated with dengue fever; however, only 65.0 % of the respondents reported skin rash as a sign of dengue fever. More than 95.0 % of respondents agreed about the seriousness and possible transmission of dengue fever; however, negative attitudes regarding the facts of being at risk of the disease and that the infection is preventable were expressed by 15.0 % of respondents. Despite the good level of knowledge and attitudes of the respondent population, poor preventive practices were common. Bivariate analysis identified poor knowledge of dengue signs and symptoms (OR = 2.1, 95 % CI = 1.24-3.68; P = 0.005) and its vector (OR = 2.1, 95 % CI = 1.14-3.84; P = 0.016) as factors significantly associated with poor preventive practices. However, multivariable analysis showed that poor knowledge of the vector is an independent predictor of poor preventive practices of the population (adjusted OR = 2.1, 95 % CI = 1.14-3.84; P = 0.018). CONCLUSION: The majority of people in urban communities of Taiz have a clear understanding of most signs/symptoms of dengue fever as well as positive attitudes towards the seriousness and possible transmissibility of dengue fever. However, negative attitudes regarding their perception of the risk and possible prevention of the infection are prevailing among a small proportion of the population and need to be targeted by educational campaigns. It appears that the good level of the population knowledge of the signs/symptoms of dengue fever and the factors contributing to the spread and control of its vectors did not translate into good practices. PMID- 27717334 TI - Early antibiotics administration during targeted temperature management after out of-hospital cardiac arrest: a nationwide database study. AB - BACKGROUND: Patients resuscitated after cardiac arrest are reportedly at high risk for infection and sepsis, especially those treated with targeted temperature management (TTM). There is, however, limited evidence suggesting that early antibiotic use improves patient outcomes. We examined the hypothesis that early treatment with antibiotics reduces mortality in patients with cardiac arrest receiving TTM. METHODS: We identified 2803 patients with cardiogenic out-of hospital cardiac arrest (OHCA) that were treated with TTM and were admitted to 371 hospitals that contribute to the Japanese Diagnosis Procedure Combination inpatient database between July 2007 and March 2013. Of these, 1272 received antibiotics within the first 2 days (antibiotics) and 1531 did not (control). We generated 802 propensity score-matched pairs. RESULTS: There was no significant difference in 30-day mortality between the groups (control vs. antibiotics; 33.0 % vs. 29.9 %; difference, 3.1 %; 95 % confidence interval [CI], -1.4 to 7.7 %, p = 0.18). Analysis using the hospital antibiotics prescribing rate as an instrumental variable showed that antibiotic use was not significantly associated with a reduction in 30-day mortality (6.6 %, CI 95 %, -0.5 to 13.7 %, p = 0.28). A subgroup analysis of patients who required extracorporeal membrane oxygenation (ECMO) indicated a significant difference in 30-day mortality between the 2 groups (62.9 % vs. 43.5 %; difference 19.3 %, CI 95 %, 5.9 to 32.7 %, p = 0.005). In the instrumental variable model, the estimated reduction in 30-day mortality associated with antibiotics was 18.2 % (CI 95 %, 21.3 to 34.4 %, p = 0.03) in ECMO patients. CONCLUSIONS: Although there was no significant association between the use of antibiotics and mortality after overall cardiogenic OHCA treated with TTM, antibiotics may be beneficial in patients who require ECMO. PMID- 27717335 TI - With or without reirradiation in advanced local recurrent nasopharyngeal carcinoma: a case-control study. AB - BACKGROUND: The study aimed to evaluate the long-term outcome in patients with advanced local recurrent nasopharyngeal carcinoma (NPC) treated with or without reirradiation. METHODS: A total of 44 patients treated without reirradiation (non RT + chemotherapy) were matched with 44 patients treated with reirradiation (re RT+/-chemtherapy) by age, sex, Karnosky performance score (KPS), rT stage, rN stage, and time interval between initial radiation and recurrence (TI). Overall survival (OS) rate and time to progression (TTP) rate were assessed using Kaplan Meier method, log-rank test, and Cox regression analysis. RESULTS: From March 2008 to December 2013, a total of 88 well-balanced rT3-4 N0-1 NPC patients were retrospectively analyzed. After a median follow-up of 27 months (range: 6-85), the 5-year OS rate and TTP rate was 23.4 %, 39.0 % in the non-RT + chemotherapy group and 27.5 %, 49.8 % in the re-RT+/-chemtherapy group, respectively. Multivariate analysis showed that significant toxic effect was the only significant prognosticator correlated with OS (HR: 2.15, 95 % CI = 1.02-4.53, p = 0.044). No statistically significant survival differences were observed between the two treatment groups in either univariate or multivariate analyses. CONCLUSION: Compared with reiradiation, treating advanced local recurrent NPC with chemotherapy alone warrants further validation in the view of its similar survival and more acceptable toxicities.

(protocol version 09.01.2015). AB - BACKGROUND: The appropriate time to initiate enteral nutrition after the placement of a percutaneous endoscopic gastrostomy (PEG) tube has been an area of limited research. There are no sufficient randomised prospective controlled trials in the paediatric population comparing the safety and tolerance of early feeding (3 h) after PEG placement. In order to reduce the period of fasting, inadequate nutritional support, and hospitalisation time, we decided to devise this study. METHODS/DESIGN: This study is a multicentre, randomised, open-label trial designed to evaluate the tolerance and safety of early enteral nutrition after PEG placement in children. Patients are randomised to receive the first feeding bolus with a polymeric diet (1 kcal/ml) via a feeding tube 3 h after the PEG placement (group I - early enteral feeding) or 8 h after the procedure (group II - late enteral feeding). The key objective of the study is to compare the tolerance and safety of the early- and late-feeding modes after PEG placement in children. The primary endpoint is the number of patients who will achieve full feed (total fluid and caloric requirements) within 48 h of the first feeding bolus. The secondary endpoints are: the number of early and late complications, the duration of hospitalisation after PEG placement, gastric residuals (ml) total in the period up to 48 h since the first feeding bolus. DISCUSSION: To our knowledge this is the first study in paediatric patients to evaluate the tolerance and safety of early enteral nutrition after PEG placement. The goal is to establish an optimum standard procedure in the group of paediatric patients qualified for the PEG insertion procedure in Poland.

AB - : BACKGROUND: Though the development and fitting of scleral contact lenses are expanding steadily, there is no simple method to provide scleral metrics for scleral contact lens fitting yet. The aim of this study was to establish formulae for estimation of the axial radius of curvature (ARC) of the anterior sclera using ocular biometric parameters that can be easily obtained with conventional devices. METHODS: A semi-automated stitching method and a computational analysis tool for calculating ARC were developed by using the ImageJ and MATLAB software. The ARC of all the ocular surface points were analyzed from the composite horizontal cross-sectional images of the right eyes of 24 volunteers; these measurements were obtained using anterior segment optical coherence tomography for a previous study (AS-OCT; Visante). Ocular biometric parameters were obtained from the same volunteers with slit-scanning topography and partial coherence interferometry. Correlation analysis was performed between the ARC at 8 mm to the axis line (ARC[8]) and other ocular parameters (including age). With ARC obtained on several nasal and temporal points (7.0, 7.5, 8.0, 8.5, and 9.0 mm from the axis line), univariate and multivariate linear regression analyses were performed to develop a model for estimating ARC with the help of ocular biometric parameters. RESULTS: Axial length, spherical equivalent, and angle kappa showed correlations with temporal ARC[8] (tARC[8]; Pearson's r = 0.653, -0.579, and 0.341; P = 0.001, 0.015, and 0.015, respectively). White-to-white corneal diameter (WTW) and anterior chamber depth (ACD) showed correlation with nasal ARC[8] (nARC[8]; Pearson's r = -0.492 and -0.461; P = 0.015 and 0.023, respectively). The formulae for estimating scleral curvatures (tARC, nARC, and average ARC) were developed as a function of axial length, ACD, WTW, and distance from the axis line, with good determinant power (72 - 80 %; SPSS ver. 22.0). Angle kappa showed strong correlation with axial length (Pearson's r = -0.813, P <0.001), and the different correlation patterns of nasal and temporal ARC with axial length can be explained by the ocular surface deviation represented by angle kappa. CONCLUSIONS: Axial length, ACD, and WTW are useful parameters for estimating the ARC of the anterior sclera, which is important for the haptic design of scleral contact lenses. Angle kappa affects the discrepancies between the nasal and temporal scleral curvature. PMID- 27717337 TI - Polymorphisms in the estrogen receptor alpha gene (ESR1), daily cycling estrogen and mammographic density phenotypes. AB - BACKGROUND: Single nucleotide polymorphisms (SNPs) involved in the estrogen pathway and SNPs in the estrogen receptor alpha gene (ESR1 6q25) have been linked to breast cancer development, and mammographic density is an established breast cancer risk factor. Whether there is an association between daily estradiol levels, SNPs in ESR1 and premenopausal mammographic density phenotypes is unknown. METHODS: We assessed estradiol in daily saliva samples throughout an entire menstrual cycle in 202 healthy premenopausal women in the Norwegian Energy Balance and Breast Cancer Aspects I study. DNA was genotyped using the Illumina Golden Gate platform. Mammograms were taken between days 7 and 12 of the menstrual cycle, and digitized mammographic density was assessed using a computer assisted method (Madena). Multivariable regression models were used to study the association between SNPs in ESR1, premenopausal mammographic density phenotypes and daily cycling estradiol. RESULTS: We observed inverse linear associations between the minor alleles of eight measured SNPs (rs3020364, rs2474148, rs12154178, rs2347867, rs6927072, rs2982712, rs3020407, rs9322335) and percent mammographic density (p-values: 0.002-0.026), these associations were strongest in lean women (BMI, <=23.6 kg/m2.). The odds of above-median percent mammographic density (>28.5 %) among women with major homozygous genotypes were 3-6 times higher than those of women with minor homozygous genotypes in seven SNPs. Women with rs3020364 major homozygous genotype had an OR of 6.46 for above-median percent mammographic density (OR: 6.46; 95 % Confidence Interval 1.61, 25.94) when compared to women with the minor homozygous genotype. These associations were not observed in relation to absolute mammographic density. No associations between SNPs and daily cycling estradiol were observed. However, we suggest, based on results of borderline significance (p values: 0.025-0.079) that the level of 17beta-estradiol for women with the minor genotype for rs3020364, rs24744148 and rs2982712 were lower throughout the cycle in women with low (<28.5 %) percent mammographic density and higher in women with high (>28.5 %) percent mammographic density, when compared to women with the major genotype. CONCLUSION: Our results support an association between eight selected SNPs in the ESR1 gene and percent mammographic density. The results need to be confirmed in larger studies. PMID- 27717340 TI - Increasing comorbidity is associated with worsening physical function and pain after primary total knee arthroplasty. AB - BACKGROUND: Previous studies suggested that pre-operative comorbidity was a risk factor for worse outcomes after TKA. To our knowledge, studies have not examined whether postoperative changes in comorbidity impact pain and function outcomes longitudinally. Our objective was to examine if increasing comorbidity postoperatively is associated with worsening physical function and pain after primary total knee arthroplasty (TKA). METHODS: We performed a retrospective chart review of veterans who had completed Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Short Form-36 (SF36) surveys at regular intervals after primary TKA. Comorbidity was assessed using a variety of scales: validated Charlson comorbidity index score, and a novel Arthroplasty Comorbidity Severity Index score (Including medical index, local musculoskeletal index [including lower extremity and spine] and TKA-related index subscales; higher scores are worse ), at multiple time-points post-TKA. We used mixed model linear regression to examine the association of worsening comorbidity post-TKA with change in WOMAC and SF-36 scores in the subsequent follow-up periods, controlling for age, length of follow-up, and repeated observations. RESULTS: The study cohort consisted of 124 patients with a mean age of 71.7 years (range 58.6 89.2, standard deviation (SD) 6.9) followed for a mean of 4.9 years post operatively (range 1.3-11.4; SD 2.8). We found that post-operative worsening of the Charlson Index score was significantly associated with worsening SF-36 Physical Function (PF) (beta coefficient (beta) = -0.07; p < 0.0001), SF-36 Bodily Pain (BP) (beta = -0.06; p = 0.002), and WOMAC PF subscale (beta = 0.08; p < 0.001; higher scores are worse) scores, in the subsequent periods. Worsening novel medical index subscale scores were significantly associated with worsening SF-36 PF scores (beta = -0.03; p = 0.002), SF-36 BP (beta = -0.04; p < 0.001) and showed a non-significant trend for worse WOMAC PF scores (beta = 0.02; p = 0.11) subsequently. Local musculoskeletal index subscale scores were significantly associated with worsening SF-36 PF (beta = -0.05; p = 0.001), SF-36 BP (beta = 0.04; p = 0.03) and WOMAC PF (beta = 0.06; p = 0.01) subsequently. None of the novel index subscale scores were significantly associated with WOMAC pain scores. TKA complications, as assessed by TKA-related index subscale, were not significantly associated with SF-36 or WOMAC domain scores. CONCLUSIONS: Increasing Charlson index as well as novel medical and local musculoskeletal index subscale scores (from novel Arthroplasty Comorbidity Severity Index) post TKA correlated with subsequent worsening of physical function and pain outcomes post-TKA. Further studies should examine which comorbidity management could have the greatest impact on these outcomes. PMID- 27717341 TI - Application of fundamental equations to species-area theory. AB - BACKGROUND: Species-area relationship (SAR), endemics-area relationship (EAR) and overlap-area relationship (OAR) are three important concepts in biodiversity study. The application of fundamental equations linking the SAR, EAR and OAR, can enrich the axiomatic framework of the species-area theory and deepen our understanding of the mechanisms of community assembly. RESULTS: Two fundamental equations are derived and extended to power law model and random replacement model of species-area distribution. Several important parameters, including the overlap index and extinction rate, are defined and expressed to enrich the species-area theory. For power law model, both EAR and OAR have three parameters, with one more parameter of the total area than SAR does. The EAR equation is a monotonically increasing function for parameter c and z, and a monotonically decreasing function for parameter A. The extinction rate, with two parameters, is a monotonically increasing function for parameter z, and a monotonically decreasing function for parameter A. The overlap index is a monotonically increasing function for parameter A, and a monotonically decreasing function for parameter z, independent of parameter c. CONCLUSIONS: The general formats of SAR, EAR, OAR, overlap index, overlap rate, sampling rate and extinction rate, are derived and extended to power law model and random replacement model as the axiomatic framework of species-area theory. In addition, if the total area is underestimated, the extinction rate will be overestimated. PMID- 27717339 TI - Refractive error characteristics in patients with congenital blepharoptosis before and after ptosis repair surgery. AB - BACKGROUND: We examined the effect of surgical repair on the pattern of refractive errors in Korean patients with congenital blepharoptosis. METHODS: We reviewed the clinical records of 54 patients with congenital blepharoptosis who attended our hospital from 2006 to 2012 and underwent a detailed refractive examination before and after ptosis repair surgery. Among them, 21 of the patients whose refractive data was available for both before and after the surgery were included in order to observe the effect of ptosis repair surgery on refractive error characteristics. The astigmatism groups were divided into three subgroups: with-the-rule (WTR), against-the-rule (ATR), and oblique astigmatism (OA). We also evaluated the severity of astigmatism. RESULTS: Before surgery, the ptotic eyes had more severe astigmatism and a greater percentage of OA than the fellow eyes. The changes in astigmatism magnitude before and after surgery were not significant, but the proportion of subjects with OA increased significantly. In ptotic eyes, amblyopia was found in 14 eyes (20.9 %). 3 eyes (4.5 %) were from solely occlusive visual stimulus deprivation due to severe ptosis, and 11 eyes were from refractive errors. Among refractive errors, amblyogenic astigmatism made up to the largest proportion of patients (8 patients, 11.9 %). CONCLUSIONS: Ptotic eyes had more severe astigmatism and more OA than fellow eyes. Amblyogenic astigmatism was more common in ptotic eyes. A change in astigmatism toward the OA axis was significantly detected after surgery, and that can be possible amblyogenic cause. Therefore, the correction of astigmatism before and after ptosis repair surgery is very important to prevent amblyopia. PMID- 27717343 TI - Factors associated with persons with disability employment in India: a cross sectional study. AB - BACKGROUND: Over twenty million persons with disability in India are increasingly being offered poverty alleviation strategies, including employment programs. This study employs a spatial analytic approach to identify correlates of employment among persons with disability in India, considering sight, speech, hearing, movement, and mental disabilities. METHODS: Based on 2001 Census data, this study utilizes linear regression and spatial autoregressive models to identify factors associated with the proportion employed among persons with disability at the district level. Models stratified by rural and urban areas were also considered. RESULTS: Spatial autoregressive models revealed that different factors contribute to employment of persons with disability in rural and urban areas. In rural areas, having mental disability decreased the likelihood of employment, while being female and having movement, or sight impairment (compared to other disabilities) increased the likelihood of employment. In urban areas, being female and illiterate decreased the likelihood of employment but having sight, mental and movement impairment (compared to other disabilities) increased the likelihood of employment. CONCLUSIONS: Poverty alleviation programs designed for persons with disability in India should account for differences in employment by disability types and should be spatially targeted. Since persons with disability in rural and urban areas have different factors contributing to their employment, it is vital that government and service-planning organizations account for these differences when creating programs aimed at livelihood development.

PMID- 27717342 TI - IMPACT is a GCN2 inhibitor that limits lifespan in Caenorhabditis elegans. AB - BACKGROUND: The General Control Nonderepressible 2 (GCN2) kinase is a conserved member of the integrated stress response (ISR) pathway that represses protein translation and helps cells to adapt to conditions of nutrient shortage. As such, GCN2 is required for longevity and stress resistance induced by dietary restriction (DR). IMPACT is an ancient protein that inhibits GCN2. RESULTS: Here, we tested whether IMPACT down-regulation mimics the effects of DR in C. elegans. Knockdown of the C. elegans IMPACT homolog impt-1 activated the ISR pathway and increased lifespan and stress resistance of worms in a gcn-2-dependent manner. Impt-1 knockdown exacerbated DR-induced longevity and required several DR activated transcription factors to extend lifespan, among them SKN-1 and DAF-16, which were induced during larval development and adulthood, respectively, in response to impt-1 RNAi. CONCLUSIONS: IMPACT inhibits the ISR pathway, thus limiting the activation of stress response factors that are beneficial during aging and required under DR.

PMID- 27717346 TI - Identification and characterization of two CD4 alleles in Microminipigs. AB - BACKGROUND: We previously identified two phenotypes of CD4+ cells with and without reactions to anti-pig CD4 monoclonal antibodies by flow cytometry in a herd of Microminipigs. In this study, we analyzed the coding sequences of CD4 and certified the expression of CD4 molecules in order to identify the genetic sequence variants responsible for the positive and negative PBMCs reactivity to anti-pig CD4 monoclonal antibodies. RESULTS: We identified two CD4 alleles, CD4.A and CD4.B, corresponding to antibody positive and negative, respectively, by nucleotide sequencing of PCR products using CD4 specific primer pairs. In comparison with the swine CD4 amino-acid sequence [GenBank: NP_001001908], CD4.A had seven amino-acid substitutions and CD4.B had 15 amino-acid substitutions. The amino-acid sequences within domain 1 of CD4.B were identical to the swine CD4.2 [GenBank: CAA46584] sequence that had been reported previously to be a modified CD4 molecule that had lost reactivity with an anti-pig CD4 antibody in NIH miniature pigs. Homozygous and heterozygous CD4.A and CD4.B alleles in the Microminipigs herd were characterised by using the RFLP technique with the restriction endonuclease, BseRI. The anti-pig CD4 antibody recognized pig PBMCs with CD4.AA and CD4.AB, but did not recognized those with CD4.BB. We transfected HeLa cells with the FLAG-tagged CD4.A or CD4.B vectors, and certified that transfected HeLa cells expressed FLAG in both vectors. The failure of cells to react with anti-CD4 antibodies in CD4.B pigs was associated to ten amino-acid substitutions in domain 1 and/or one amino-acid substitution in joining region 3 of CD4.B. We also found exon 8 was defective in some CD4.A and CD4.B resulting in the loss of the transmembrane domain, which implies that these CD4 proteins are secreted from helper T cells into the circulation. CONCLUSIONS: We identified that amino-acids substitutions of domain 1 in CD4.B gave rise to the failure of some CD4 expressing cells to react with particular anti-pig CD4 monoclonal antibodies. In addition, we developed a PCR-RFLP method that enabled us to simply identify the CD4 sequence variant and the positive and negative PBMCs reactivity to our anti-pig CD4 monoclonal antibodies without the need to use flow cytometric analysis. PMID- 27717348 TI - Patterns of privilege: A total cohort analysis of admission and academic outcomes for Maori, Pacific and non-Maori non-Pacific health professional students. AB - BACKGROUND: Tertiary institutions are struggling to ensure equitable academic outcomes for indigenous and ethnic minority students in health professional study. This demonstrates disadvantaging of ethnic minority student groups (whereby Indigenous and ethnic minority students consistently achieve academic outcomes at a lower level when compared to non-ethnic minority students) whilst privileging non-ethnic minority students and has important implications for health workforce and health equity priorities. Understanding the reasons for academic inequities is important to improve institutional performance. This study explores factors that impact on academic success for health professional students by ethnic group. METHODS: Kaupapa Maori methodology was used to analyse data for 2686 health professional students at the University of Auckland in 2002-2012. Data were summarised for admission variables: school decile, Rank Score, subject credits, Auckland school, type of admission, and bridging programme; and academic outcomes: first-year grade point average (GPA), first-year passed all courses, year 2 - 4 programme GPA, graduated, graduated in the minimum time, and composite completion for Maori, Pacific, and non-Maori non-Pacific (nMnP) students. Statistical tests were used to identify significant differences between the three ethnic groupings. RESULTS: Maori and Pacific students were more likely to attend low decile schools (27 % Maori, 33 % Pacific vs. 5 % nMnP, p < 0.01); complete bridging foundation programmes (43 % Maori, 50 % Pacific vs. 5 % nMnP, p < 0.01), and received lower secondary school results (Rank Score 197 Maori, 178 Pacific vs. 231 nMnP, p < 0.01) when compared with nMnP students. Patterns of privilege were seen across all academic outcomes, whereby nMnP students achieved higher first year GPA (3.6 Maori, 2.8 Pacific vs. 4.7 nMnP, p < 0.01); were more likely to pass all first year courses (61 % Maori, 41 % Pacific vs. 78 % nMnP, p < 0.01); to graduate from intended programme (66 % Maori, 69 % Pacific vs. 78 % nMnP, p < 0.01); and to achieve optimal completion (9 % Maori, 2 % Pacific vs. 20 % nMnP, p < 0.01) when compared to Maori and Pacific students. CONCLUSIONS: To meet health workforce and health equity goals, tertiary institution staff should understand the realities and challenges faced by Maori and Pacific students and ensure programme delivery meets the unique needs of these students. Ethnic disparities in academic outcomes show patterns of privilege and should be alarming to tertiary institutions. If institutions are serious about achieving equitable outcomes for Maori and Pacific students, major institutional changes are necessary that ensure the unique needs of Maori and Pacific students are met. PMID- 27717347 TI - Associations between musculoskeletal pain and work-related factors among public service sector computer workers in Kaunas County, Lithuania. AB - BACKGROUND: Information technologies in occupational activities have been developing very rapid. Epidemiological studies have shown that musculoskeletal disorders are widely prevalent among employees working with a computer. The aim of this study was to evaluate the prevalence of musculoskeletal pain in various anatomical areas and its associations with individual, ergonomic, and psychosocial factors among computer workers of the public sector in Kaunas County, Lithuania. METHODS: The investigation consisting of two parts - questionnaire study (Nordic Musculoskeletal Questionnaire and Copenhagen Psychosocial Questionnaire) and direct observation (evaluation of work ergonomics using the Rapid Upper Limb Assessment [RULA]) - was carried out in three randomly selected public sector companies of Kaunas County. The representative study sample comprised 513 public service office workers. The prevalence of musculoskeletal pain in five anatomical areas of the body (shoulders, elbows, wrists/hands, as well as upper and low back) was evaluated. RESULTS: The prevalence rates of shoulder, elbow, wrist/hand, upper and low back pain were 50.5 %, 20.3 %, 26.3 %, 44.8 %, and 56.1 %, respectively. Individual factors such as gender, age, computer work experience, and body mass index were found as significant for musculoskeletal pain in various musculoskeletal regions. The respondents reporting pain in shoulder, wrist/hand, upper back, and low back areas had a statistically significantly higher mean RULA score. The duration of working with a computer was found as a significant factor for shoulder pain. High quantitative demands were related to musculoskeletal pain in all investigated anatomical areas expect for the low back; weak social support was a significant predictor for complaints in upper and low back areas. CONCLUSION: This study confirmed associations between musculoskeletal pain and work ergonomics; therefore, preventive measures at the workplace should be directed to the improvement in ergonomic work environment, education, and workload optimization. PMID- 27717349 TI - An efficient algorithm for identifying primary phenotype attractors of a large scale Boolean network. AB - BACKGROUND: Boolean network modeling has been widely used to model large-scale biomolecular regulatory networks as it can describe the essential dynamical characteristics of complicated networks in a relatively simple way. When we analyze such Boolean network models, we often need to find out attractor states to investigate the converging state features that represent particular cell phenotypes. This is, however, very difficult (often impossible) for a large network due to computational complexity. RESULTS: There have been some attempts to resolve this problem by partitioning the original network into smaller subnetworks and reconstructing the attractor states by integrating the local attractors obtained from each subnetwork. But, in many cases, the partitioned subnetworks are still too large and such an approach is no longer useful. So, we have investigated the fundamental reason underlying this problem and proposed a novel efficient way of hierarchically partitioning a given large network into smaller subnetworks by focusing on some attractors corresponding to a particular phenotype of interest instead of considering all attractors at the same time. Using the definition of attractors, we can have a simplified update rule with fixed state values for some nodes. The resulting subnetworks were small enough to find out the corresponding local attractors which can be integrated for reconstruction of the global attractor states of the original large network. CONCLUSIONS: The proposed approach can substantially extend the current limit of Boolean network modeling for converging state analysis of biological networks. PMID- 27717350 TI - Incidence of bovine neonatal pancytopenia in 243 farms in Germany. AB - BACKGROUND: Several research groups from different European countries have worked on the aetiopathogenesis of bovine neonatal pancytopenia (BNP) and an association between the use of the vaccine PregSure BVD (Pfizer, Germany) and the development of this haemorrhagic disease was confirmed. Because BNP is not a notifiable disease, it is difficult to obtain information on its incidence. Based on pharmacovigilance (PhV) data, which are the only officially available data at the national level, the incidence of BNP is considered low. However, voluntary reporting of the disease can lead to underreporting. To gain more insight into the incidence of BNP among the affected herds, an epidemiological study was performed, which focused on 243 farms in Germany with cases of BNP. Farmers were asked to report the occurrence of BNP, including the number of cases, which allowed calculation of incidence in the affected herds. Matching such data with the registered cases in the National PhV System (NPhVS) gave us an opportunity to assess the extent of BNP underreporting. RESULTS: On 243 farms, a total of 1195 calves younger than 4 weeks with haemorrhagic diathesis were registered. In 58 % of the reports, a diagnosis of BNP was confirmed by blood analysis and or by necropsy. The number of cases observed on individual farms ranged from 1 to 80. Based on these results, the incidence of BNP on affected farms ranged from 0.3 to 15.2 % (median 2.9 %). The maximal incidence in the year with the highest number of BNP calves ranged between 0.4 and 18.6 % (median 3.3 %). Comparing the number of cases registered in the NPhVS to the numbers found in this study revealed considerable underreporting to the national database: only 44 % of the farms and 41 % of the BNP calves included in the study were registered in the NPhVS. CONCLUSIONS: In spite of the opportunity to report BNP calves to the Paul-Ehrlich Institut (Langen, Germany), the estimated number of undetected BNP cases is remarkably high. However, even if the revealed substantial underreporting is taken into account, the incidence of BNP is low. Nevertheless, the incidence on some affected farms is very high, resulting in considerable financial losses that should not be underestimated. Although the exact pathomechanism of BNP at the molecular level is still not known, its incidence is clearly declining following withdrawal of PregSure BVD from the market. PMID- 27717351 TI - Improvement in delivery of type 2 diabetes services differs by mode of care: a retrospective longitudinal analysis in the Aboriginal and Torres Strait Islander Primary Health Care setting. AB - BACKGROUND: Addressing evidence-practice gaps in primary care remains a significant public health challenge and is likely to require action at different levels of the health system. Whilst Continuous Quality Improvement (CQI) is associated with improvements in overall delivery, little is known about delivery of different types of care processes, and their relative improvement during CQI. METHODS: We used data from over 15,000 clinical audit records of clients with Type 2 diabetes collected as part of a wide-scale CQI program implemented between 2005 and 2014 in 162 Aboriginal and Torres Strait Islander health centres. We abstracted data from clinical records on 15 service items recommended in clinical guidelines and categorised these items into five modes of care on the basis of the mechanism through which care is delivered: laboratory tests; generalist delivered physical checks; specialist-delivered checks; education/counselling for nutrition and physical activity and education/counselling for high risk substance use. We calculated delivery for each patient for each of mode of care by determining the proportion of recommended services delivered for that mode. We used multilevel regression models to quantify variation attributable to health centre or client level factors and to identify factors associated with greater adherence to clinical guidelines for each mode of care. RESULTS: Clients on average received 43 to 60 % of recommended care in 2005/6. Different modes of care showed different patterns of improvement. Generalist-delivered physical checks (delivered by a non-specialist) showed a steady year on year increase, delivery of laboratory tests showed improvement only in the later years of the study, and delivery of counselling/education interventions showed early improvement which then plateaued. Health centres participating in CQI had increased odds of top quartile service delivery for all modes compared to baseline, but effects differed by mode. Health centre factors explained 20-52 % of the variation across jurisdictions and health centres for different modes of care. CONCLUSIONS: Levels of adherence to clinical guidelines and patterns of improvement during participation in a CQI program differed for different modes of care. Policy and funding decisions may have had important effects on the level and nature of improvements achieved. PMID- 27717352 TI - Analyses of inter-rater reliability between professionals, medical students and trained school children as assessors of basic life support skills. AB - BACKGROUND: Training of lay-rescuers is essential to improve survival-rates after cardiac arrest. Multiple campaigns emphasise the importance of basic life support (BLS) training for school children. Trainings require a valid assessment to give feedback to school children and to compare the outcomes of different training formats. Considering these requirements, we developed an assessment of BLS skills using MiniAnne and tested the inter-rater reliability between professionals, medical students and trained school children as assessors. METHODS: Fifteen professional assessors, 10 medical students and 111-trained school children (peers) assessed 1087 school children at the end of a CPR-training event using the new assessment format. Analyses of inter-rater reliability (intraclass correlation coefficient; ICC) were performed. RESULTS: Overall inter-rater reliability of the summative assessment was high (ICC = 0.84, 95 %-CI: 0.84 to 0.86, n = 889). The number of comparisons between peer-peer assessors (n = 303), peer-professional assessors (n = 339), and peer-student assessors (n = 191) was adequate to demonstrate high inter-rater reliability between peer- and professional-assessors (ICC: 0.76), peer- and student-assessors (ICC: 0.88) and peer- and other peer-assessors (ICC: 0.91). Systematic variation in rating of specific items was observed for three items between professional- and peer assessors. CONCLUSION: Using this assessment and integrating peers and medical students as assessors gives the opportunity to assess hands-on skills of school children with high reliability. PMID- 27717353 TI - Achieving universal health coverage in South Africa through a district health system approach: conflicting ideologies of health care provision. AB - BACKGROUND: Universal Health Coverage (UHC) has emerged as a major goal for health care delivery in the post-2015 development agenda. It is viewed as a solution to health care needs in low and middle countries with growing enthusiasm at both national and global levels. Throughout the world, however, the paths of countries to UHC have differed. South Africa is currently reforming its health system with UHC through developing a national health insurance (NHI) program. This will be practically achieved through a decentralized approach, the district health system, the main vehicle for delivering services since democracy. METHODS: We utilize a review of relevant documents, conducted between September 2014 and December 2015 of district health systems (DHS) and UHC and their ideological underpinnings, to explore the opportunities and challenges, of the district health system in achieving UHC in South Africa. RESULTS: Review of data from the NHI pilot districts suggests that as South Africa embarks on reforms toward UHC, there is a need for a minimal universal coverage and emphasis on district particularity and positive discrimination so as to bridge health inequities. The disparities across districts in relation to health profiles/demographics, health delivery performance, management of health institutions or district management capacity, income levels/socio-economic status and social determinants of health, compliance with quality standards and above all the burden of disease can only be minimised through positive discrimination by paying more attention to underserved and disadavantaged communities. CONCLUSIONS: We conclude that in South Africa the DHS is pivotal to health reform and UHC may be best achieved through minimal universal coverage with positive discrimination to ensure disparities across districts in relation to disease burden, human resources, financing and investment, administration and management capacity, service readiness and availability and the health access inequalities are consciously implicated. Yet ideological and practical issues make its achievement problematic. PMID- 27717354 TI - Establishment of an innovative staging system for extramedullary plasmacytoma. AB - BACKGROUND: Extramedullary plasmacytoma (EMP) is a rare malignant disease that lacks a unique clinical staging system to predict the survival of EMP patients and to design individualized treatment. Instead, clinicians have chosen to use the multiple myeloma (MM) staging system. METHODS: Forty-eight EMP patients treated between 1996 and 2014 were included in this study. The new clinical stages were established according to independent survival factors using Cox regression model. RESULTS: Lymph node metastasis and a larger primary tumor (>=5 cm) were the only two independent poor prognostic factors for overall survival (OS) and disease-free survival (P < 0.05). Stage I was defined as the disease without those two poor prognostic factors. Stage II was defined as the presence of either factor, and Stage III was defined as the presence of both factors. OS was significantly different in each stage of the new staging system (P < 0.001), with a median follow-up time for Stage I, Stage II and Stage III of 68, 23 and 14 months. The new staging system had enhanced prognostic value compared to the MM staging system (the area under ROC 0.763 versus 0.520, P = 0.044). Although no difference was observed between treatments in Stage I, the combination treatment was associated with a significantly beneficial OS in the late stages (5-year OS: 15.3 % versus 79.5 %; P = 0.032). CONCLUSIONS: The new staging system exhibited a promising prognostic value for survival and could aid clinicians in choosing the most suitable treatment for EMP patients.

AB - BACKGROUND: Phylogenetic diversity and evolutionary distinctiveness are highly valuable components of biodiversity, but they are rarely considered in conservation practices. Focusing on a biodiversity hotspot, the Mediterranean Basin, we aimed to identify those areas where evolutionary history is highly threatened and range-restricted in the region. Using null models, we first compared the spatial distributions of three indices: two measured threatened evolutionary history-Expected PDloss and Heightened Evolutionary distinctiveness and Global Endangerment-and one measured endemic evolutionary history Biogeographically Evolutionary Distinctiveness. We focused on three vertebrate groups with high proportions of endemic, threatened species: amphibians, squamates and terrestrial mammals. Second, we estimated the spatial overlap of hotspots of threatened and endemic evolutionary history within the network of protected areas under several conservation scenarios. RESULTS: Areas that concentrate evolutionary history of conservation interest greatly differed among taxa and indices, although a large proportion of hotspots were identified in the Maghreb, in the East of the Mediterranean Basin as well as in islands. We found that, in a minimum conservation scenario, there was a significant proportion of hotspots for amphibians and squamates that were protected but not for terrestrial mammals. However, in a strong conservation scenario, only few hotspots overlapped with protected areas and they were significantly less protected than in a model where hotspots were chosen randomly. CONCLUSIONS: Some sites concentrate highly threatened and range-restricted evolutionary history of the Mediterranean basin and their conservation could be much improved. These sites are relevant for conservation studies aimed at designing new conservation actions to preserve evolutionary history and the option values it represents. PMID- 27717356 TI - Estimating the costs for the treatment of abortion complications in two public referral hospitals: a cross-sectional study in Ouagadougou, Burkina Faso. AB - BACKGROUND: Treatment costs of induced abortion complications can consume a substantial amount of hospital resources. This use of hospitals scarce resources to treat induced abortion complications may affect hospitals' capacities to deliver other health care services. In spite of the importance of studying the burden of the treatment of induced abortion complications, few studies have been conducted to document the costs of treating abortion complications in Burkina Faso. Our objective was to estimate the costs of six abortion complications including incomplete abortion, hemorrhage, shock, infection/sepsis, cervix or vagina laceration, and uterus perforation treated in two public referral hospital facilities in Ouagadougou and the cost saving of providing safe abortion care services. METHODS: The distribution of abortion-related complications was assessed through a review of postabortion care-registers combined with interviews with key informants in maternity wards and in hospital facilities. Two structured questionnaires were used for data collection following the perspective of the hospital. The first questionnaire collected information on the units and the unit costs of drugs and medical supplies used in the treatment of each complication. The second questionnaire gathered information on salaries and overhead expenses. All data were entered in a spreadsheet designed for studying abortion, and analyses were performed on Excel 2007. RESULTS: Across six types of abortion complications, the mean cost per patient was USD45.86. The total cost to these two public referral hospital facilities for treating the complications of abortion was USD22,472.53 in 2010 equivalent to USD24,466.21 in 2015. Provision of safe abortion care services to women who suffered from complications of unsafe induced abortion and who received care in these public hospitals would only have cost USD2,694, giving potential savings of more than USD19,778.53 in that year. CONCLUSIONS: The treatment of the complications of abortion consumes a significant proportion (up to USD22,472.53) of the two public hospitals resources in Burkina Faso. Safe abortion care services may represent a cost beneficial alternative, as it may have saved USD19,778.53 in 2010. PMID- 27717357 TI - Perfusion index assessment during transition period of newborns: an observational study. AB - BACKGROUND: Perfusion index (PI) is becoming a part of clinical practice in neonatology to monitor peripheral perfusion noninvasively. Hemodynamic and respiratory changes occur in newborns during the transition period after birth in which peripheral perfusion may be affected. Tachypnea is a frequent symptom during this period. While some tachypneic newborns get well in less than 6 h and diagnosed as "delayed transition", others get admitted to intensive care unit which transient tachypnea of newborn (TTN) being the most common diagnosis among them. We aimed to compare PI of neonates with TTN and delayed transition with controls, and assess its value on discrimination of delayed transition and TTN. METHODS: Neonates with gestational age between 37 and 40 weeks who were born with elective caesarian section were included. Eligible neonates were monitored with Masimo Set Radical7 pulse-oximeter (Masimo Corp., Irvine, CA, USA). Postductal PI, oxygen saturation and heart rate were manually recorded every 10 s for 3 min for two defined time periods as 10th minute and 1st hour. Axillary temperature were also recorded. Newborn infants were grouped as control, delayed transition, and TTN. RESULTS: Forty-nine tachypneic (TTN; 21, delayed transition; 28) and 30 healthy neonates completed the study. PI values were similar between three groups at both periods. There were no correlation between PI and respiratory rate, heart rate, and temperature. CONCLUSION: PI assessment in maternity unit does not discriminate TTN from delayed transitional period in newborns which may indicate that peripheral perfusion is not severely affected in either condition. PMID- 27717358 TI - smokeSALUD: exploring the effect of demographic change on the smoking prevalence at municipality level in Austria. AB - BACKGROUND: Reducing the smoking population is still high on the policy agenda, as smoking leads to many preventable diseases, such as lung cancer, heart disease, diabetes, and more. In Austria, data on smoking prevalence only exists at the federal state level. This provides an interesting overview about the current health situation, but for regional planning authorities these data are often insufficient as they can hide pockets of high and low smoking prevalence in certain municipalities. METHODS: This paper presents a spatial-temporal change of estimated smokers for municipalities from 2001 and 2011. A synthetic dataset of smokers is built by combining individual large-scale survey data and small area census data using a deterministic spatial microsimulation approach. Statistical analysis, including chi-square test and binary logistic regression, are applied to find the best variables for the simulation model and to validate its results. RESULTS: As no easy-to-use spatial microsimulation software for non-programmers is available yet, a flexible web-based spatial microsimulation application for health decision support (called simSALUD) has been developed and used for these analyses. The results of the simulation show in general a decrease of smoking prevalence within municipalities between 2001 and 2011 and differences within areas are identified. These results are especially valuable to policy decision makers for future planning strategies. CONCLUSIONS: This case study shows the application of smokeSALUD to model the spatial-temporal changes in the smoking population in Austria between 2001 and 2011. This is important as no data on smoking exists at this geographical scale (municipality). However, spatial microsimulation models are useful tools to estimate small area health data and to overcome these problems. The simulations and analysis should support health decision makers to identify hot spots of smokers and this should help to show where to spend health resources best in order to reduce health inequalities. PMID- 27717359 TI - Potential use of mobile phones in improving animal health service delivery in underserved rural areas: experience from Kilosa and Gairo districts in Tanzania. AB - BACKGROUND: Sub-optimal performance of the animal health delivery system in rural areas is common in developing countries including Tanzania. However, penetration of mobile phones and availability of good road network and public transport systems offer opportunities for improving the access of rural communities to diagnostic and advisory services from facilities and expertise located in urban areas. A questionnaire survey on possession and use of mobile phones by pastoral and agro-pastoral communities in Kilosa and Gairo districts was carried out between November and December 2015. A total number of 138 livestock keepers from three villages of Chakwale (54), Mvumi (41) and Parakuyo (43) participated in the study. An e-based system was designed and tested to link rural communities with urban diagnostic facilities. RESULTS: It was observed that the average number of phones possessed by individuals interviewed and household families was 1.1 +/- 0.26 (1-2) and 3.5 +/- 2.23 (1-10), respectively. It was further observed that out of 138 livestock keepers interviewed, 133 (96.4 %) had feature phones while 10 (7.2 %) of them possessed smartphones. Mobile phone is currently used to support livestock production by communicating on animal health in Parakuyo (18, 41.9 %), Mvumi (18, 43.9 %) and Chakwale (14, 25.9 %). Other contributions of mobile phones in livestock and crop agriculture observed in the study area include: exchange of livestock price information, crop price information, communicating on plant health/diseases, livestock extension and advisory services as well as crop farming extension and advisory services. We also designed and tested an e-based SUAVetDiag(r) system to support timely diagnosis of infectious disease conditions and prompt advice on case management in veterinary underserved areas. CONCLUSIONS: Availability of mobile phones in rural areas, in combination with supporting infrastructure and facilities in urban areas, has potential to stimulate local development and improving delivery of animal health and extension services. It is recommended that more development and refinement of the system should be conducted to ensure that this potential is tapped to revolutionalise delivery of animal health services in rural areas. PMID- 27717360 TI - The effect of changing the built environment on physical activity: a quantitative review of the risk of bias in natural experiments. AB - BACKGROUND: Evidence regarding the association of the built environment with physical activity is influencing policy recommendations that advocate changing the built environment to increase population-level physical activity. However, to date there has been no rigorous appraisal of the quality of the evidence on the effects of changing the built environment. The aim of this review was to conduct a thorough quantitative appraisal of the risk of bias present in those natural experiments with the strongest experimental designs for assessing the causal effects of the built environment on physical activity. METHODS: Eligible studies had to evaluate the effects of changing the built environment on physical activity, include at least one measurement before and one measurement of physical activity after changes in the environment, and have at least one intervention site and non-intervention comparison site. Given the large number of systematic reviews in this area, studies were identified from three exemplar systematic reviews; these were published in the past five years and were selected to provide a range of different built environment interventions. The risk of bias in these studies was analysed using the Cochrane Risk of Bias Assessment Tool: for Non Randomized Studies of Interventions (ACROBAT-NRSI). RESULTS: Twelve eligible natural experiments were identified. Risk of bias assessments were conducted for each physical activity outcome from all studies, resulting in a total of fifteen outcomes being analysed. Intervention sites included parks, urban greenways/trails, bicycle lanes, paths, vacant lots, and a senior citizen's centre. All outcomes had an overall critical (n = 12) or serious (n = 3) risk of bias. Domains with the highest risk of bias were confounding (due to inadequate control sites and poor control of confounding variables), measurement of outcomes, and selection of the reported result. CONCLUSIONS: The present review focused on the strongest natural experiments conducted to date. Given this, the failure of existing studies to adequately control for potential sources of bias highlights the need for more rigorous research to underpin policy recommendations for changing the built environment to increase physical activity. Suggestions are proposed for how future natural experiments in this area can be improved. PMID- 27717361 TI - Effect of intraarticular inoculation of mesenchymal stem cells in dogs with hip osteoarthritis by means of objective force platform gait analysis: concordance with numeric subjective scoring scales. AB - BACKGROUND: Subjective pain assessment scales have been widely used for assessing lameness in response to pain, but the accuracy of these scales has been questioned. To assess scale accuracy, 10 lame, presa Canario dogs with osteoarthritis (OA) associated with bilateral hip dysplasia were first treated with mesenchymal stem cells. Then, potential lameness improvement was analyzed using two pain scales (Bioarth and visual analog scale). These data were compared with similar data collected using a force platform with the same animals during a period of 6 months after treatment. RESULTS: The F test for intraclass correlation showed that concordance in pain/lameness scores between the 2 measuring methodologies was not significant (P value >= 0.9213; 95 % confidence interval, -0.56, 0.11). Although subjective pain assessment showed improvement after 6 months, force platform data demonstrated those same animals had returned to the initial lameness state. CONCLUSION: Use of pain assessment scales to measure lameness associated with OA did not have great accuracy and concordance when compared with quantitative force platform gait analysis. PMID- 27717362 TI - High genetic diversity among extraintestinal Escherichia coli isolates in pullets and layers revealed by a longitudinal study. AB - BACKGROUND: Various information about the genetic diversity of Escherichia coli isolates from chickens are available but a detailed epidemiological investigation based upon isolates obtained from interrelated pullet and layer flocks is still missing. Therefore, in the course of a longitudinal epidemiological study on pullets and layers, 144 E. coli isolates from chickens with or without pathological lesions of the reproductive tract were serotyped and genotyped with pulsed-field gel electrophoresis (PFGE). These isolates were collected during rearing, peak and at the end of production. The actual study is the first of its kind so as to elucidate genetic relatedness among extraintestinal E. coli isolated from chickens with varying pathological conditions in interrelated layer farms/flocks at different stages of rearing. RESULTS: Serotyping revealed that 63.19 % of the isolates could not be assigned to any of the three serotypes tested whereas 30.55 % of the isolates belonged to serotype O1:K1, 4.86 % to O2:K1 and 1.38 % to O78:K80. After macrorestriction digest with XbaI, 91.66 % of the isolates were typeable resulting in 96 distinct PFGE profiles. Among them, five PFGE types included isolates collected from diseased chickens as well as from birds without pathological lesions. This finding shows that pathogenicity of E. coli in layers seems to be largely influenced by concurrent susceptibility factors. Furthermore, in six out of eight cases where two isolates were collected from each of eight birds, different PFGE types were found in the same or different organs of the same bird. The existence of predominant or persistent E. coli genotypes was only observed in two cases. CONCLUSIONS: It is concluded that extraintestinal E. coli genotypes and serotypes in pullets and layers are heterogenous and also do not maintain a single clonality within the same bird. The facts that E. coli strains did not show any definite clonal population structure based on geographical region, age of the host and pathological lesions should have relevance in further epidemiological studies and control strategies. PMID- 27717363 TI - Content-based analysis of Ki-67 stained meningioma specimens for automatic hot spot selection. AB - BACKGROUND: Hot-spot based examination of immunohistochemically stained histological specimens is one of the most important procedures in pathomorphological practice. The development of image acquisition equipment and computational units allows for the automation of this process. Moreover, a lot of possible technical problems occur in everyday histological material, which increases the complexity of the problem. Thus, a full context-based analysis of histological specimens is also needed in the quantification of immunohistochemically stained specimens. One of the most important reactions is the Ki-67 proliferation marker in meningiomas, the most frequent intracranial tumour. The aim of our study is to propose a context-based analysis of Ki-67 stained specimens of meningiomas for automatic selection of hot-spots. METHODS: The proposed solution is based on textural analysis, mathematical morphology, feature ranking and classification, as well as on the proposed hot-spot gradual extinction algorithm to allow for the proper detection of a set of hot-spot fields. The designed whole slide image processing scheme eliminates such artifacts as hemorrhages, folds or stained vessels from the region of interest. To validate automatic results, a set of 104 meningioma specimens were selected and twenty hot-spots inside them were identified independently by two experts. The Spearman rho correlation coefficient was used to compare the results which were also analyzed with the help of a Bland-Altman plot. RESULTS: The results show that most of the cases (84) were automatically examined properly with two fields of view with a technical problem at the very most. Next, 13 had three such fields, and only seven specimens did not meet the requirement for the automatic examination. Generally, the Automatic System identifies hot-spot areas, especially their maximum points, better. Analysis of the results confirms the very high concordance between an automatic Ki-67 examination and the expert's results, with a Spearman rho higher than 0.95. CONCLUSION: The proposed hot-spot selection algorithm with an extended context-based analysis of whole slide images and hot-spot gradual extinction algorithm provides an efficient tool for simulation of a manual examination. The presented results have confirmed that the automatic examination of Ki-67 in meningiomas could be introduced in the near future. PMID- 27717364 TI - Meaningful engagement of people living with HIV who use drugs: methodology for the design of a Peer Research Associate (PRA) hiring model. AB - BACKGROUND: Community-based HIV, harm reduction, and addiction research increasingly involve members of affected communities as Peer Research Associates (PRAs)-individuals with common experiences to the participant population (e.g. people who use drugs, people living with HIV [PLHIV]). However, there is a paucity of literature detailing the operationalization of PRA hiring and thus limited understanding regarding how affected communities can be meaningfully involved through low-barrier engagement in paid positions within community-based participatory research (CBPR) projects. We aim to address this gap by describing a low-threshold PRA hiring process. RESULTS: In 2012, the BC Centre for Excellence in HIV/AIDS and the Dr. Peter AIDS Foundation collaborated to develop a mixed-method CBPR project evaluating the effectiveness of the Dr. Peter Centre (DPC)-an integrative HIV care facility in Vancouver, Canada. A primary objective of the study was to assess the impact of DPC services among clients who have a history of illicit drug use. In keeping with CBPR principles, affected populations, community-based organizations, and key stakeholders guided the development and dissemination of a low-barrier PRA hiring process to meaningfully engage affected communities (e.g. PLHIV who have a history of illicit drug use) in all aspects of the research project. The hiring model was implemented in a number of stages, including (1) the establishment of a hiring team; (2) the development and dissemination of the job posting; (3) interviewing applicants; and (4) the selection of participants. The hiring model presented in this paper demonstrates the benefits of hiring vulnerable PLHIV who use drugs as PRAs in community-based research. CONCLUSIONS: The provision of low-barrier access to meaningful research employment described herein attempts to engage affected communities beyond tokenistic involvement in research. Our hiring model was successful at engaging five PRAs over a 2-year period and fostered opportunities for future paid employment or volunteer opportunities through ongoing collaboration between PRAs and a diverse range of stakeholders working in HIV/AIDS and addictions. Additionally, this model has the potential to be used across a range of studies and community-based settings interested in meaningfully engaging communities in all stages of the research process. PMID- 27717365 TI - Severe active C3 glomerulonephritis triggered by immune complexes and inactivated after eculizumab therapy. AB - BACKGROUND: Understanding the role of alternative complement pathway dysregulation in membranoproliferative glomerulonephritis (MPGN) has led to a dramatic shift in its classification into two subgroups: immune complex-mediated MPGN and complement-mediated MPGN, consisting of dense deposit disease and C3 glomerulonephritis (C3GN). A limited number of C3GN cases have been published to date with not yet conclusive results since the novel therapeutic approach with eculizumab was introduced. CASE PRESENTATION: We report the clinical follow-up of a 16-year-old patient in whom a diagnosis of C3GN was confirmed by immunofluorescence and electron microscopy in second and third kidney biopsies, while the first biopsy revealed idiopathic immune complex-mediated MPGN type III, Anders and Strife variant, which failed to improve after several attempts at conventional immunosuppression therapy. Although applied late in an already fairly advanced stage of the severe active form of MPGN, the efficacy of eculizumab on C3GN was evidenced clinically and pathohistologically. Its beneficial influence on pathomorphogenesis was demonstrated by a unique follow-up in the last three biopsies, despite the recent observation, confirmed in this study, of eculizumab binding within the kidney tissue. CONCLUSIONS: Clinicians and pathologists should be aware that, in some patients, an underlying genetic or acquired complement alternative pathway abnormality can be masked by an initial immune complex-mediated mechanism, which subsequently triggers an unbalanced excessive continual driving of complement terminal pathway activation and the development of C3GN. In such a patient, supplementary steroids in addition to eculizumab appear necessary to achieve an adequate response. PMID- 27717366 TI - A cross-sectional national survey assessing self-reported drug intake behavior, contact with the primary sector and drug treatment among service users of Danish drug consumption rooms. AB - BACKGROUND: Drug consumption rooms (DCRs) have been implemented worldwide as a harm-reducing strategy. In 2012, Denmark passed legislation allowing establishment of DCRs. The aim of this study was to identify characteristics and gain knowledge of the way service users use the DCRs including bridge building to specialized health care. Associations between nationality, opioid substitution treatment (OST), drug intake method, and response to staff advice on harm reducing education was investigated, as well as service user's reasons for using the DCRs, and their perceptions of safety and trust in the DCRs. METHODS: A survey questionnaire sampled 154 participants of DCRs. Convenience sampling was used. Key variables covered demographics, drug intake mode, educational advice received in the DCR, and opinions about and role of the DCRs for the service users. RESULTS: Only 10 % of the participants were under the age of 30, 30 % between 30 and 39 years, 36 % between 40 and 49 years, and 24 % age 50 or more. A total of 60 % of the participants had encountered drugs before they were 19 years old. Female participants were 25 %, and 73 % were Danish citizens, 8 % were non Danish EU citizens, and 18 % were non-EU citizens. As drug intake method, 63 % injected drugs in a vein, 7 % sniffed, and 37 % smoked. Of drugs used in the DCR, 49 % used cocaine, 41 % heroin, 16 % a mix of heroin and cocaine, and 16 % used methadone. Participants who smoked drugs made significantly less use of drug rehabilitation than participants who sniffed or injected drugs. There was a similar rate of advice on OST across nationality. Participants accepted staff education on hygienic measures and safe injection practices and found it useful. Participants felt safe and trusted staff and bridge building to specialized health care took place in the DCR. CONCLUSIONS: Staff of Danish DCRs educate service users on health related issues and harm-reducing interventions. A subgroup who smoke and a subgroup of nationality other than Danish are underserved and have less likely been in OST. More research on these groups is needed. PMID- 27717367 TI - A multiplex urinary immunoassay for bladder cancer detection: analysis of a Japanese cohort. AB - BACKGROUND: Bladder cancer (BCa) is among the most commonly diagnosed malignancies worldwide, and due the high rate of post-operative disease recurrence, it is one of the most prevalent in many countries. The development of non-invasive molecular assays that can accurately detect and monitor BCa would be a major advance, benefiting both patients and healthcare systems. We have previously identified a urinary protein biomarker panel that is being developed for application in at-risk patient cohorts. Here, we investigated the potential utility of the multiplex assay in a Japanese cohort. METHODS: The Japanese study cohort collected from urology clinics at two institutions was comprised of a total of 288 subjects. The protein biomarker panel (IL8, MMP9, MMP10, ANG, APOE, SDC1, A1AT, PAI1, CA9, VEGFA) was monitored in voided urine samples collected prior to cystoscopy using a custom multiplex ELISA assay. The diagnostic performance of the biomarker panel was assessed using receiver operator curves, predictive modeling and descriptive statistics. RESULTS: Urinary biomarker concentrations were significantly elevated in cases versus controls, and in cases with high-grade and muscle-invasive tumors. The AUC for the 10-biomarker assay was 0.892 (95 % confidence interval 0.850-0.934), with an overall diagnostic sensitivity specificity of 0.85 and 0.81, respectively. A predictive model trained on the larger institutional cohort correctly identified 99 % of the cases from the second institution. CONCLUSIONS: Urinary levels of a 10-biomarker panel enabled discrimination of patients with BCa. The multiplex urinary diagnostic assay has the potential to be developed for the non-invasive detection of BCa in at-risk Japanese patients. PMID- 27717368 TI - Overview of harm reduction in prisons in seven European countries. AB - While the last decade has seen a growth of support for harm reduction around the world, the availability and accessibility of quality harm reduction services in prison settings is uneven and continues to be inadequate compared to the progress achieved in the broader community. This article provides a brief overview of harm reduction in prisons in Catalonia (Spain), Greece, Ireland, Italy, Latvia, Poland, and Portugal. While each country provides a wide range of harm reduction services in the broader community, the majority fail to provide these same services or the same quality of these services, in prison settings, in clear violation of international human rights law and minimum standards on the treatment of prisoners. Where harm reduction services have been available and easily accessible in prison settings for some time, better health outcomes have been observed, including significantly reduced rates of HIV and HCV incidence. While the provision of harm reduction in each of these countries' prisons varies considerably, certain key themes and lessons can be distilled, including around features of an enabling environment for harm reduction, resource allocation, collection of disaggregated data, and accessibility of services.

PMID- 27717369 TI - Overexpression of AtOxR gene improves abiotic stresses tolerance and vitamin C content in Arabidopsis thaliana. AB - BACKGROUND: Abiotic stresses are serious threats to plant growth, productivity and result in crop loss worldwide, reducing average yields of most major crops. Although abiotic stresses might elicit different plant responses, most induce the accumulation of reactive oxygen species (ROS) in plant cells leads to oxidative damage. L-ascorbic acid (AsA, vitamin C) is known as an antioxidant and H2O2 scavenger that defends plants against abiotic stresses. In addition, vitamin C is also an important component of human nutrition that has to be obtained from different foods. Therefore, increasing the vitamin C content is important for improving abiotic stresses tolerance and nutrition quality in crops production. RESULTS: Here, we show that the expression of AtOxR gene is response to multiple abiotic stresses (salt, osmotic, metal ion, and H2O2 treatment) in both the leaves and roots of Arabidopsis. AtOxR protein was localized to the Endoplasmic Reticulum (ER) in yeast and Arabidopsis cells by co-localization analysis with ER specific dye. AtOxR-overexpressing transgenic Arabidopsis plants enhance the tolerance to abiotic stresses. Overexpression of AtOxR gene resulted in AsA accumulation and decreased H2O2 content in transgenic plants. CONCLUSIONS: In this study, our results show that AtOxR responds to multiple abiotic stresses. Overexpressing AtOxR improves tolerance to abiotic stresses and increase vitamin C content in Arabidopsis thaliana. AtOxR will be useful for the improvement of important crop plants through moleculer breeding. PMID- 27717371 TI - Basic science of electronic cigarettes: assessment in cell culture and in vivo models. AB - Electronic cigarettes (e-cigarettes, ECIGs) were introduced into the market a decade ago as an alternative to tobacco smoking. Whether ECIGs are safe and whether they qualify as smoking cessation tool is currently unknown. Their use has markedly expanded in that period, despite the fact that potential toxic effects of the vapour created by the e-cigarette and the nicotine-containing cartridge fluid have been incompletely studied. Marketing targets diverse groups including older smokers but also young people. Whereas the adverse health effects of nicotine inhaled by users of ECIGs has been well documented, less is known about the other components. An increasing number of in vitro and in vivo studies demonstrate a range of adverse effects of both the vapour created by ECIGs as well as the nicotine-containing fluid. Importantly, these studies demonstrate that toxicity from ECIGs, although this may be less than that caused by tobacco products, not only arises from its nicotine content. Furthermore, there are no data on the long-term consequences of ECIG use. The wide range of ECIG products available to consumers and the lack of standardisation of toxicological approaches towards ECIG evaluation complicates the assessment of adverse health effects of their use. Here we review the current data on preclinical studies on ECIGs describing their effects in cell culture and animal models. PMID- 27717373 TI - DNA ligase IV syndrome; a review. AB - DNA ligase IV deficiency is a rare primary immunodeficiency, LIG4 syndrome, often associated with other systemic features. DNA ligase IV is part of the non homologous end joining mechanism, required to repair DNA double stranded breaks. Ubiquitously expressed, it is required to prevent mutagenesis and apoptosis, which can result from DNA double strand breakage caused by intracellular events such as DNA replication and meiosis or extracellular events including damage by reactive oxygen species and ionising radiation.Within developing lymphocytes, DNA ligase IV is required to repair programmed DNA double stranded breaks induced during lymphocyte receptor development.Patients with hypomorphic mutations in LIG4 present with a range of phenotypes, from normal to severe combined immunodeficiency. All, however, manifest sensitivity to ionising radiation. Commonly associated features include primordial growth failure with severe microcephaly and a spectrum of learning difficulties, marrow hypoplasia and a predisposition to lymphoid malignancy. Diagnostic investigations include immunophenotyping, and testing for radiosensitivity. Some patients present with microcephaly as a predominant feature, but seemingly normal immunity. Treatment is mainly supportive, although haematopoietic stem cell transplantation has been used in a few cases. PMID- 27717372 TI - Development of a programmed cell death ligand-1 immunohistochemical assay validated for analysis of non-small cell lung cancer and head and neck squamous cell carcinoma. AB - BACKGROUND: A high-quality programmed cell-death ligand 1 (PD-L1) diagnostic assay may help predict which patients are more likely to respond to anti programmed cell death-1 (PD-1)/PD-L1 antibody-based cancer therapy. Here we describe a PD-L1 immunohistochemical (IHC) staining protocol developed by Ventana Medical Systems Inc. and key analytical parameters of its use in formalin-fixed, paraffin-embedded (FFPE) samples of non-small cell lung cancer (NSCLC) and head and neck squamous cell carcinoma (HNSCC). METHODS: An anti-human PD-L1 rabbit monoclonal antibody (SP263) was optimized for use with the VENTANA OptiView DAB IHC Detection Kit on the automated VENTANA BenchMark ULTRA platform. The VENTANA PD-L1 (SP263) Assay was validated for use with FFPE NSCLC and HNSCC tissue samples in a series of studies addressing sensitivity, specificity, robustness, and precision. Samples from a subset of 181 patients from a Phase 1/2 study of durvalumab (NCT01693562) were analyzed to determine the optimal PD-L1 staining cut-off for enriching the probability of responses to treatment. The scoring algorithm was defined using statistical analysis of clinical response data from this clinical trial and PD-L1 staining parameters in HNSCC and NSCLC tissue. Inter-reader agreement was established by three pathologists who evaluated 81 NSCLC and 100 HNSCC samples across the range of PD-L1 expression levels. RESULTS: The VENTANA PD-L1 (SP263) Assay met all pre-defined acceptance criteria. For both cancer types, a cut-off of 25 % of tumor cells with PD-L1 membrane staining of any intensity best discriminated responders from nonresponders. Samples with staining above this value were deemed to have high PD-L1 expression, and those with staining below it were deemed to have low or no PD-L1 expression. Inter reader agreement on PD-L1 status was 97 and 92 % for NSCLC and HNSCC, respectively. CONCLUSIONS: These results highlight the robustness and reproducibility of the VENTANA PD-L1 (SP263) Assay and support its suitability for use in the evaluation of NSCLC and HNSCC FFPE tumor samples using the devised >=25 % tumor cell staining cut-off in a clinical setting. The clinical utility of the PD-L1 diagnostic assay as a predictive biomarker will be further validated in ongoing durvalumab studies. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01693562. PMID- 27717374 TI - The NSPCC UK Minding the Baby(r) (MTB) home-visiting programme, supporting young mothers (aged 14-25) in the first 2 years of their baby's life: study protocol for a randomised controlled trial. AB - BACKGROUND: Young mothers living in low-income urban settings often are exposed to significant and chronic environmental difficulties including poverty, social isolation and poor education and typically also have to cope with personal histories of abuse and depression. Minding the Baby(r) (MTB) is an interdisciplinary home-visiting programme developed to support first-time young mothers, which integrates primary care and mental health approaches into a single intensive intervention from the last trimester of pregnancy until the child's second birthday. The primary aim of the intervention is to promote caregiver sensitivity, and, secondarily, to promote both child and maternal socioemotional outcomes. METHODS/DESIGN: This is a multisite randomised controlled trial (RCT) with a target recruitment of 200 first-time adolescent mothers (under 26 years of age). One hundred participants will be randomised to the MTB group and they will receive the MTB programme in addition to the usual services available in their areas. Those participants not allocated to MTB will receive Treatment as Usual (TAU) only. Researchers will carry out blind assessments at baseline (before the birth of the baby), and outcome assessments around the child's first and second birthdays. The primary outcome will be the quality of maternal sensitivity and the secondary outcomes will focus on attachment security, child cognitive/language development, behavioural problems, postponed childbearing, maternal mental health and incidents of child protection interventions. DISCUSSION: This study evaluates the Minding the Baby(r) programme in the UK. In particular, this RCT explores the effectiveness of this integrative approach, which focusses on maternal mental issues as well as parent-infant interaction, parental concerns and developmental outcomes.

AB - Several species of beta-amyloid peptides (Abeta) exist as a result of differential cleavage from amyloid precursor protein (APP) to yield various C terminal Abeta peptides. Several N-terminal modified Abeta peptides have also been identified in Alzheimer's disease (AD) brains, the most common of which is pyroglutamate-modified Abeta (AbetapE3-42). AbetapE3-42 peptide has an increased propensity to aggregate, appears to accumulate in the brain before the appearance of clinical symptoms of AD, and precedes Abeta1-42 deposition. Moreover, in vitro studies have shown that AbetapE3-42 can act as a seed for full length Abeta1-42. In this study, we characterized the Drosophila model of AbetapE3-42 toxicity by expressing the peptide in specific sets of neurons using the GAL4-UAS system, and measuring different phenotypic outcomes. We found that AbetapE3-42 peptide had an increased propensity to aggregate. Expression of AbetapE3-42 in the neurons of adult flies led to behavioural dysfunction and shortened lifespan. Expression of AbetapE3-42 constitutively in the eyes led to disorganised ommatidia, and activation of the c-Jun N-terminal kinase (JNK) signaling pathway. The eye disruption was almost completely rescued by co-expressing a candidate Abeta degrading enzyme, neprilysin2. Furthermore, we found that neprilysin2 was capable of degrading AbetapE3-42. Also, we tested the seeding hypothesis for AbetapE3-42 in vivo, and measured its effect on Abeta1-42 levels. We found that Abeta1-42 levels were significantly increased when Abeta1-42 and AbetapE3-42 peptides were co-expressed. Furthermore, we found that AbetapE3-42 enhanced Abeta1-42 toxicity in vivo. Our findings implicate AbetapE3-42 as an important source of toxicity in AD, and suggest that its specific degradation could be therapeutic. PMID- 27717376 TI - Rapid and efficient generation of neural progenitors from adult bone marrow stromal cells by hypoxic preconditioning. AB - BACKGROUND: Bone marrow stromal cells (BMSCs) are attractive as a source of neural progenitors for ex vivo generation of neurons and glia. Limited numbers of this subpopulation, however, hinder translation into autologous cell-based therapy. Here, we demonstrate rapid and efficient conditioning with hypoxia to enrich for these neural progenitor cells prior to further expansion in neurosphere culture. METHOD: Adherent cultures of BMSCs (rat/human) were subjected to 1 % oxygen for 24 h and then subcultured as neurospheres with epidermal growth factor (EGF) and basic fibroblast growth factor supplementation. Neurospheres and cell progeny were monitored immunocytochemically for marker expression. To generate Schwann cell-like cells, neurospheres were plated out and exposed to gliogenic medium. The resulting cells were co-cultured with purified dorsal root ganglia (rat) neurons and then tested for commitment to the Schwann cell fate. Fate-committed Schwann cells were subjected to in vitro myelination assay. RESULTS: Transient hypoxic treatment increased the size and number of neurospheres generated from both rat and human BMSCs. This effect was EGF dependent and attenuated with the EGF receptor inhibitor erlotinib. Hypoxia did not affect the capacity of neurospheres to generate neuron- or glia-like precursors. Human Schwann cell-like cells generated from hypoxia-treated BMSCs demonstrated expression of S100beta /p75 and capacity for myelination in vitro. CONCLUSION: Enhancing the yield of neural progenitor cells with hypoxic preconditioning of BMSCs in vitro but without inherent risks of genetic manipulation provides a platform for upscaling production of neural cell derivatives for clinical application in cell-based therapy. PMID- 27717378 TI - Worst case optimization for interfractional motion mitigation in carbon ion therapy of pancreatic cancer. AB - INTRODUCTION: The efficacy of radiation therapy treatments for pancreatic cancer is compromised by abdominal motion which limits the spatial accuracy for dose delivery - especially for particles. In this work we investigate the potential of worst case optimization for interfractional offline motion mitigation in carbon ion treatments of pancreatic cancer. METHODS: We implement a worst case optimization algorithm that explicitly models the relative biological effectiveness of carbon ions during inverse planning. We perform a comparative treatment planning study for seven pancreatic cancer patients. Treatment plans that have been generated using worst case optimization are compared against (1) conventional intensity-modulated carbon ion therapy, (2) single field uniform dose carbon ion therapy, and (3) an ideal yet impractical scenario relying on daily re-planning. The dosimetric quality and robustness of the resulting treatment plans is evaluated using reconstructions of the daily delivered dose distributions on fractional control CTs. RESULTS: Idealized daily re-planning consistently gives the best dosimetric results with regard to both target coverage and organ at risk sparing. The absolute reduction of D 95 within the gross tumor volume during fractional dose reconstruction is most pronounced for conventional intensity-modulated carbon ion therapy. Single field uniform dose optimization exhibits no substantial reduction for six of seven patients and values for D 95 for worst case optimization fall in between. The treated volume (D>95 % prescription dose) outside of the gross tumor volume is reduced by a factor of two by worst case optimization compared to conventional optimization and single field uniform dose optimization. Single field uniform dose optimization comes at an increased radiation exposure of normal tissues, e.g. ~2 Gy (RBE) in the mean dose in the kidneys compared to conventional and worst case optimization and ~4 Gy (RBE) in D 1 in the spinal cord compared to worst case optimization. CONCLUSION: Interfractional motion substantially deteriorates dose distributions for carbon ion treatments of pancreatic cancer patients. Single field uniform dose optimization mitigates the negative influence of motion on target coverage at an increased radiation exposure of normal tissue. Worst case optimization enables an exploration of the trade-off between robust target coverage and organ at risk sparing during inverse treatment planning beyond margin concepts. PMID- 27717377 TI - Immune response in peripheral axons delays disease progression in SOD1G93A mice. AB - BACKGROUND: Increasing evidence suggests that the immune system has a beneficial role in the progression of amyotrophic lateral sclerosis (ALS) although the mechanism remains unclear. Recently, we demonstrated that motor neurons (MNs) of C57SOD1G93A mice with slow disease progression activate molecules classically involved in the cross-talk with the immune system. This happens a lot less in 129SvSOD1G93A mice which, while expressing the same amount of transgene, had faster disease progression and earlier axonal damage. The present study investigated whether and how the immune response is involved in the preservation of motor axons in the mouse model of familial ALS with a more benign disease course. METHODS: First, the extent of axonal damage, Schwann cell proliferation, and neuromuscular junction (NMJ) denervation were compared between the two ALS mouse models at the disease onset. Then, we compared the expression levels of different immune molecules, the morphology of myelin sheaths, and the presence of blood-derived immune cell infiltrates in the sciatic nerve of the two SOD1G93A mouse strains using immunohistochemical, immunoblot, quantitative reverse transcription PCR, and rotating-polarization Coherent Anti-Stokes Raman Scattering techniques. RESULTS: Muscle denervation, axonal dysregulation, and myelin disruption together with reduced Schwann cell proliferation are prominent in 129SvSOD1G93A compared to C57SOD1G93A mice at the disease onset, and this correlates with a faster disease progression in the first strain. On the contrary, a striking increase of immune molecules such as CCL2, MHCI, and C3 was seen in sciatic nerves of slow progressor C57SOD1G93A mice and this was accompanied by heavy infiltration of CD8+ T lymphocytes and macrophages. These phenomena were not detectable in the peripheral nervous system of fast progressing mice. CONCLUSIONS: These data show for the first time that damaged MNs in SOD1-related ALS actively recruit immune cells in the peripheral nervous system to delay muscle denervation and prolong the lifespan. On the contrary, the lack of this response has a negative impact on the disease course. PMID- 27717380 TI - Local versus intravenous injections of skeletal muscle precursor cells in nonhuman primates with acute or chronic intrinsic urinary sphincter deficiency. AB - BACKGROUND: Many factors may influence the efficacy of cell therapy for intrinsic urinary sphincter deficiency (ISD), including the route of administration of the cells and the condition of the sphincter. The goal of this study was to compare local versus intravenous administration of autologous skeletal muscle precursor cells (skMPCs) when administered to nonhuman primates (NHPs) with either acute or chronic ISD. METHODS: Thirty-two adult female monkeys were divided into eight groups (n = 4/group): (1) control; (2) surgically induced ISD/no treatment; (3) acute ISD (6-week duration)/local vehicle only; (4) acute ISD/local skMPC injection; (5) acute ISD/systemic skMPC; (6) chronic ISD (6-month duration)/local vehicle; (7) chronic ISD/local skMPC; (8) chronic ISD/systemic skMPC. Maximal urethral pressures (MUP) were measured prior to ISD, prior to treatment and at 3 and 6 months following treatment. Quantitative histology was used to measure muscle/collagen content, somatic innervation, and vascularity of the sphincter complexes. RESULTS: In NHPs with acute ISD both systemic and local administration of skMPCs increased resting MUP values and sphincter muscle content (p < 0.05 vs. ISD/vehicle). However, the effects of systemic skMPC administration were significantly lower than those of local injection (p > 0.05). In NHPs with chronic ISD local skMPC administration had reduced (compared to NHPs with acute ISD) effects on MUP and sphincter muscle values (p < 0.05 vs. acute ISD/skMPC); systemic administration had no effect. Pudendal nerve-stimulated increases in MUP were significant only in acute ISD NHPs with local skMPC treatment (p < 0.05 vs. resting MUP). The extent of sphincter vascularization and innervation were directly related to MUP and sphincter muscle content. CONCLUSIONS: Both the chronicity of ISD and the route of cell injection influence the efficacy of cell therapy in monkey models of ISD. This may be related to the relative ability of cells to stimulate vascularization and re-innervation in these different treatment conditions. PMID- 27717379 TI - Biohybrid cochlear implants in human neurosensory restoration. AB - BACKGROUND: The success of cochlear implantation may be further improved by minimizing implantation trauma. The physical trauma of implantation and subsequent immunological sequelae can affect residual hearing and the viability of the spiral ganglion. An ideal electrode should therefore decrease post implantation trauma and provide support to the residual spiral ganglion population. Combining a flexible electrode with cells producing and releasing protective factors could present a potential means to achieve this. Mononuclear cells obtained from bone marrow (BM-MNC) consist of mesenchymal and hematopoietic progenitor cells. They possess the innate capacity to induce repair of traumatized tissue and to modulate immunological reactions. METHODS: Human bone marrow was obtained from the patients that received treatment with biohybrid electrodes. Autologous mononuclear cells were isolated from bone marrow (BM-MNC) by centrifugation using the RegenlabTM THT-centrifugation tubes. Isolated BM-MNC were characterised using flow cytometry. In addition, the release of cytokines was analysed and their biological effect tested on spiral ganglion neurons isolated from neonatal rats. Fibrin adhesive (TissealTM) was used for the coating of silicone-based cochlear implant electrode arrays for human use in order to generate biohybrid electrodes. Toxicity of the fibrin adhesive and influence on insertion, as well on the cell coating, was investigated. Furthermore, biohybrid electrodes were implanted in three patients. RESULTS: Human BM-MNC release cytokines, chemokines, and growth factors that exert anti-inflammatory and neuroprotective effects. Using fibrin adhesive as a carrier for BM-MNC, a simple and effective cell coating procedure for cochlear implant electrodes was developed that can be utilised on-site in the operating room for the generation of biohybrid electrodes for intracochlear cell-based drug delivery. A safety study demonstrated the feasibility of autologous progenitor cell transplantation in humans as an adjuvant to cochlear implantation for neurosensory restoration. CONCLUSION: This is the first report of the use of autologous cell transplantation to the human inner ear. Due to the simplicity of this procedure, we hope to initiate its widespread utilization in various fields. PMID- 27717381 TI - Critical evaluation of the Illumina MethylationEPIC BeadChip microarray for whole genome DNA methylation profiling. AB - BACKGROUND: In recent years the Illumina HumanMethylation450 (HM450) BeadChip has provided a user-friendly platform to profile DNA methylation in human samples. However, HM450 lacked coverage of distal regulatory elements. Illumina have now released the MethylationEPIC (EPIC) BeadChip, with new content specifically designed to target these regions. We have used HM450 and whole-genome bisulphite sequencing (WGBS) to perform a critical evaluation of the new EPIC array platform. RESULTS: EPIC covers over 850,000 CpG sites, including >90 % of the CpGs from the HM450 and an additional 413,743 CpGs. Even though the additional probes improve the coverage of regulatory elements, including 58 % of FANTOM5 enhancers, only 7 % distal and 27 % proximal ENCODE regulatory elements are represented. Detailed comparisons of regulatory elements from EPIC and WGBS show that a single EPIC probe is not always informative for those distal regulatory elements showing variable methylation across the region. However, overall data from the EPIC array at single loci are highly reproducible across technical and biological replicates and demonstrate high correlation with HM450 and WGBS data. We show that the HM450 and EPIC arrays distinguish differentially methylated probes, but the absolute agreement depends on the threshold set for each platform. Finally, we provide an annotated list of probes whose signal could be affected by cross-hybridisation or underlying genetic variation. CONCLUSION: The EPIC array is a significant improvement over the HM450 array, with increased genome coverage of regulatory regions and high reproducibility and reliability, providing a valuable tool for high-throughput human methylome analyses from diverse clinical samples. PMID- 27717382 TI - Discovery of immunodominant T-cell epitopes reveals penton protein as a second immunodominant target in human adenovirus infection. AB - BACKGROUND: Human adenovirus (HAdV) infections remain a significant cause of morbidity and mortality after hematopoietic stem cell transplantation (HSCT). Efficient antiviral T-cell responses are necessary to clear infection, which is hampered by delayed immune reconstitution and medical immunosuppression after HSCT. Protective immunity may be conferred by adoptive transfer of HAdV-specific T cells. For identification of patients at risk and monitoring of treatment responses diligent assessment of anti-HAdV cellular immune responses is crucial. The HAdV-derived protein hexon has been recognized as a major immunodominant target across HAdV species. We aimed at identifying further targets of protective anti-HAdV immune response and characterizing immunogenic epitopes. METHODS: Nineteen candidate nonamers from hexon and penton proteins were identified by epitope binding prediction. Peptides were synthesized and tested for in vivo immunogenicity by screening peripheral blood mononuclear cells from healthy volunteers (n = 64) and HAdV-infected stem cell recipients (n = 26) for memory T cells recognizing the candidate epitopes in the context of most common HLA alleles. RESULTS: Functional CD8+ T cells recognizing seven epitopes were identified, among them four penton-derived and two hexon-derived peptides. The HLA-A*01-restricted penton-derived peptide STDVASLNY (A01PentonSTDV) and HLA-A*02 restricted hexon-derived peptide TLLYVLFEV (A02HexonTLLY) were recognized by more than half of the persons carrying the respective HLA-type. CONCLUSIONS: Thus, the HAdV-derived penton protein is a novel major target of the anti-HAdV immune response. Identification of new immunodominant epitopes will facilitate and broaden immune assessment strategies to identify patients suitable for T-cell transfer. Knowledge of additional target structures may increase T-cell recovery in manufacturing processes. PMID- 27717383 TI - Left ventricular diastolic function is strongly correlated with active emptying of the left atrium: a novel analysis using three-dimensional echocardiography. AB - BACKGROUND: Increased left atrial (LA) dimensions are known to be a risk factor in predicting cardiovascular events and mortality and to be one key diagnostic tool to assess diastolic dysfunction. Currently, LA measurements are usually conducted using 2D-echocardiography, although there are well-known limitations. Real-time 3D-echocardiography is able to overcome these limitations, furthermore being a valid measurement tool compared to reference standards (e.g. cardiac magnetic resonance imaging). We investigated LA function and volume and their association to left ventricular (LV) diastolic function, using newly designed and validated software for 3D-echocardiographic analysis. This software is the first to allow for a sophisticated analysis of both passive and active LA emptying. METHODS: We analyzed 2D- and 3D-echocardiographic measurements of LA volume and function in 56 subjects and compared the results between patients with normal LV diastolic function (NDF) (n = 30, 52 +/- 15 years, BMI 24.7 +/- 2.6 kg/m2) and patients in which diastolic dysfunction (DDF) was suspected (n = 26, 65 +/- 9 years, BMI 26.7 +/- 3.7 kg/m2). RESULTS: Volumes during LA active emptying were significantly smaller in DDF compared to NDF (active atrial stroke volume (ASV): 3.0 (0.1-4.5) vs. 5.5 (2.7-7.8) ml, p = 0.005; True-EF: 7.3(0.1-11.5) vs. 16.2 (8.1-25.4) %, p = 0.002). Furthermore, ASV showed a stronger association to E/e'mean than all other measured LA volumes (beta = - 0.35, p = 0.008). Neither total stroke LA volume, nor maximum or minimum LA volume differed significantly between the groups. CONCLUSIONS: Diastolic LV dysfunction results in a reduction in active LA emptying, which is more strongly associated with LV filling pressure than other previously investigated LA parameters. PMID- 27717384 TI - Preoperative plasma growth-differentiation factor-15 for prediction of acute kidney injury in patients undergoing cardiac surgery. AB - BACKGROUND: Growth-differentiation factor-15 (GDF-15) is an emerging humoral marker for risk stratification in cardiovascular disease. Cardiac-surgery associated acute kidney injury (CSA-AKI), an important complication in patients undergoing cardiac surgery, is associated with poor prognosis. The present secondary analysis of an observational cohort study aimed to determine the role of GDF-15 in predicting CSA-AKI compared with the Cleveland-Clinic Acute Renal Failure (CC-ARF) score and a logistic regression model including variables associated with renal dysfunction. METHODS: Preoperative plasma GDF-15 was determined in 1176 consecutive patients undergoing elective cardiac surgery. Patients with chronic kidney disease stage 5 were excluded. AKI was defined according to Kidney-Disease-Improving-Global-Outcomes (KDIGO) - creatinine criteria. The following variables were screened for association with development of postoperative AKI: age, gender, additive Euroscore, serum creatinine, duration of cardiopulmonary bypass, duration of surgery, type of surgery, total circulatory arrest, preoperative hemoglobin, preoperative oxygen-supplemented cerebral oxygen saturation, diabetes mellitus, hemofiltration during ECC, plasma GDF-15, high sensitivity troponin T (hsTNT), and N-terminal prohormone of B-type natriuretic peptide (NTproBNP). RESULTS: There were 258 patients (21.9 %) with AKI (AKI stage 1 (AKI-1), n = 175 (14.9 %); AKI-2, n = 6 (0.5 %); AKI-3, n = 77 (6.5 %)). The incidence of AKI-1 and AKI-3 increased significantly from the lowest to the highest tertiles of GDF-15. In logistic regression, preoperative GDF-15, additive Euroscore, age, plasma creatinine, diabetes mellitus, and duration of cardiopulmonary bypass were independently associated with AKI. Inclusion of GDF-15 in a logistic regression model comprising these variables significantly increased the area under the curve (AUC 0.738 without and 0.750 with GDF-15 included) and the net reclassification ability to predict AKI. Comparably, in receiver operating characteristic analysis the predictive capacity of the CC-ARF score (AUC 0.628) was improved by adding GDF-15 (AUC 0.684) but this score also had lower predictability than the logistic regression model. In random forest analyses the predictive capacity of GDF-15 was especially pronounced in patients with normal plasma creatinine. CONCLUSION: This suggests that preoperative plasma GDF-15 independently predicts postoperative AKI in patients undergoing elective cardiac surgery and is particularly helpful for risk stratification in patients with normal creatinine. TRIAL REGISTRATION: NCT01166360 on July 20, 2010. PMID- 27717385 TI - L1 and L2 gene polymorphisms in HPV-58 and HPV-33: implications for vaccine design and diagnosis. AB - BACKGROUND: Cervical cancer is associated with infection by certain subtypes of human papillomavirus (HPV). The L1 protein comprising HPV vaccine formulations elicits high-titre neutralizing antibodies and confers protection against specific HPV subtypes. HPV L2 protein is an attractive candidate for cross protective vaccines. HPV-33 and HPV-58 are very prevalent among Chinese women. METHODS: To study the gene intratypic variations and polymorphisms of HPV-33 and HPV-58 L1/L2 in Sichuan China, HPV-33 and HPV-58 L1 and L2 genes were sequenced and compared with other genes submitted to GenBank. Phylogenetic trees were constructed by maximum-likelihood and the Kimura 2-parameters methods (MEGA 6). The secondary structure was analyzed by PSIPred software, and HPV-33 and HPV-58 L1 homology models were created by SWISS-MODEL software. The selection pressures acting on the L1/L2 genes were estimated by PAML 4.8. RESULTS: Among 124 HPV-33 L1 sequences 20 single nucleotide mutations were observed included 8/20 non synonymous and 12/20 synonymous mutations. The 101 HPV-33 L2 sequences included 12 single nucleotide mutations comprising 7/12 non-synonymous and 5/12 synonymous mutations. The 223 HPV-58 L1 sequences included 32 single nucleotide mutations comprising 9/32 non-synonymous and 23/32 synonymous mutations. The 201 HPV-58 L2 sequences comprised 26 single nucleotide mutations including 9/26 non-synonymous and 17/26 synonymous mutations. Selective pressure analysis showed that most of the common non-synonymous mutations showed a positive selection. HPV-33 and HPV 58 L2 were more stable than HPV-33 and HPV-58 L1. CONCLUSIONS: HPV-33 and HPV-58 L2 were better candidates as clinical diagnostic targets compared with HPV-33 and HPV-58 L1. Clinical diagnostic probes and second-generation polyvalent vaccines should be designed on the basis of the unique sequence of HPV-33 and 58 L1/L2 variations in Sichuan, to improve the accuracy of clinical detection and the protective efficiency of vaccines. PMID- 27717386 TI - Metabolic engineering of Corynebacterium glutamicum for enhanced production of 5 aminovaleric acid. AB - BACKGROUND: 5-Aminovaleric acid (5AVA) is an important five-carbon platform chemical that can be used for the synthesis of polymers and other chemicals of industrial interest. Enzymatic conversion of L-lysine to 5AVA has been achieved by employing lysine 2-monooxygenase encoded by the davB gene and 5 aminovaleramidase encoded by the davA gene. Additionally, a recombinant Escherichia coli strain expressing the davB and davA genes has been developed for bioconversion of L-lysine to 5AVA. To use glucose and xylose derived from lignocellulosic biomass as substrates, rather than L-lysine as a substrate, we previously examined direct fermentative production of 5AVA from glucose by metabolically engineered E. coli strains. However, the yield and productivity of 5AVA achieved by recombinant E. coli strains remain very low. Thus, Corynebacterium glutamicum, a highly efficient L-lysine producing microorganism, should be useful in the development of direct fermentative production of 5AVA using L-lysine as a precursor for 5AVA. Here, we report the development of metabolically engineered C. glutamicum strains for enhanced fermentative production of 5AVA from glucose. RESULTS: Various expression vectors containing different promoters and origins of replication were examined for optimal expression of Pseudomonas putida davB and davA genes encoding lysine 2 monooxygenase and delta-aminovaleramidase, respectively. Among them, expression of the C. glutamicum codon-optimized davA gene fused with His6-Tag at its N Terminal and the davB gene as an operon under a strong synthetic H36 promoter (plasmid p36davAB3) in C. glutamicum enabled the most efficient production of 5AVA. Flask culture and fed-batch culture of this strain produced 6.9 and 19.7 g/L (together with 11.9 g/L glutaric acid as major byproduct) of 5AVA, respectively. Homology modeling suggested that endogenous gamma-aminobutyrate aminotransferase encoded by the gabT gene might be responsible for the conversion of 5AVA to glutaric acid in recombinant C. glutamicum. Fed-batch culture of a C. glutamicum gabT mutant-harboring p36davAB3 produced 33.1 g/L 5AVA with much reduced (2.0 g/L) production of glutaric acid. CONCLUSIONS: Corynebacterium glutamicum was successfully engineered to produce 5AVA from glucose by optimizing the expression of two key enzymes, lysine 2-monooxygenase and delta aminovaleramidase. In addition, production of glutaric acid, a major byproduct, was significantly reduced by employing C. glutamicum gabT mutant as a host strain. The metabolically engineered C. glutamicum strains developed in this study should be useful for enhanced fermentative production of the novel C5 platform chemical 5AVA from renewable resources. PMID- 27717387 TI - The associations between sedentary behaviour and mental health among adolescents: a systematic review. AB - BACKGROUND: With technological developments and modernised sedentary lifestyles has come an increase in diseases associated with inactivity such as obesity and other non-communicable diseases. Emerging evidence suggests that time spent sedentary may also interact with mental health. This systematic review examined the associations between sedentary behaviour and mental health problems among adolescents. METHODS: This systematic review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses, and applied a quality assessment tool for quantitative studies to identity best available evidence. Following stringent search strategy of the databases; Cumulative Index to Nursing and Allied Health Literature, Global Health, Health Source: Nursing and Academic Edition, MEDLINE, PsychARTICLES and PsycINFO, we identified 32 articles eligible for review. RESULTS: All studies reported leisure screen time among adolescents, and two thirds of identified studies examined depressive symptomatology. Other mental health measures were; anxiety symptoms, self-esteem, suicide ideation, loneliness, stress, and psychological distress. Strong consistent evidence was found for the relationship between both depressive symptomatology and psychological distress, and time spent using screens for leisure. Moderate evidence supported the relationship between low self-esteem and screen use. Poorer mental health status was found among adolescents using screen time more than 2-3 h per day, and gender differences exist. Essential information was missing for quality of evidence including heterogeneity in mental health and screen time-based measures, and self-report data collection methods. CONCLUSIONS: The findings are of particular significance given the global public health concern of lifestyle-attributed diseases and the possibility for novel approaches to mental health. Future research should examine the psychological impact of reducing time spent using screens for leisure among adolescents, whilst accounting for possible confounding factors such as physical activity and dietary behaviours. It is critical that the reciprocal relationship between lifestyle behaviours and mental health is represented in both the psychiatric and public health forum. PMID- 27717388 TI - Performance-based incentives may be appropriate to address challenges to delivery of prevention of vertical transmission of HIV services in rural Mozambique: a qualitative investigation. AB - BACKGROUND: Performance-based incentives (PBIs) have garnered global attention as a promising strategy to improve healthcare delivery to vulnerable populations. However, literature gaps in the context in which an intervention is implemented and how the PBIs were developed exist. Therefore, we (1) characterized the barriers and promoters to prevention of vertical transmission of HIV (PVT) service delivery in rural Mozambique, where the vertical transmission rate is 12 %, and (2) assessed the appropriateness for a PBI's intervention and application to PVT. METHODS: We conducted 24 semi-structured interviews with nurses, volunteers, community health workers, and traditional birth attendants about the barriers and promoters they experienced delivering PVT services. We then explored emergent themes in subsequent focus group discussions (n = 7, total participants N = 92) and elicited participant perspectives on PBIs. The ecological motivation opportunity-ability framework guided our iterative data collection and thematic analysis processes. RESULTS: The interviews revealed that while all health worker cadres were motivated intrinsically and by social recognition, they were dissatisfied with low and late remuneration. Facility-based staff were challenged by factors across the rest of the ecological levels, primarily in the opportunity domain, including the following: poor referral and record systems (work mandate), high workload, stock-outs, poor infrastructure (facility environment), and delays in obtaining patient results and donor payment discrepancies (administrative). Community-based cadres' opportunity challenges included lack of supplies, distance (work environment), lack of incorporation into the health system (administration), and ability challenges of incorrect knowledge (health worker). PBIs based on social recognition and that enable action on intrinsic motivation through training, supervision, and collaboration were thought to have the most potential for targeting improvements in record and referral systems and better integrating community-based health workers into the health system. Concerns about the implementation of incentives included neglect of non-incentivized tasks and distorted motivation among colleagues. CONCLUSIONS: We found that highly motivated health workers encountered severe opportunity challenges in their PVT mandate. PBIs have the potential to address key barriers that facility- and community-based health workers encounter when delivering PVT services, specifically by building upon existing intrinsic motivation and leveraging highly valued social recognition. We recommend a controlled intervention to monitor incentives' effects on worker motivation and non-incentivized tasks to generate insights about the feasibility of PBIs to improve the delivery of PVT services. PMID- 27717389 TI - "That's enough patients for everyone!": Local stakeholders' views on attracting patients into Barbados and Guatemala's emerging medical tourism sectors. AB - BACKGROUND: Medical tourism has attracted considerable interest within the Latin American and Caribbean (LAC) region. Governments in the region tout the economic potential of treating foreign patients while several new private hospitals primarily target international patients. This analysis explores the perspectives of a range of medical tourism sector stakeholders in two LAC countries, Guatemala and Barbados, which are beginning to develop their medical tourism sectors. These perspectives provide insights into how beliefs about international patients are shaping the expanding regional interest in medical tourism. METHODS: Structured around the comparative case study methodology, semi-structured interviews were conducted with 50 medical tourism stakeholders in each of Guatemala and Barbados (n = 100). To capture a comprehensive range of perspectives, stakeholders were recruited to represent civil society (n = 5/country), health human resources (n = 15/country), public health care and tourism sectors (n = 15/country), and private health care and tourism sectors (n = 15/country). Interviews were transcribed verbatim, coded using a collaborative process of scheme development, and analyzed thematically following an iterative process of data review. RESULTS: Many Guatemalan stakeholders identified the Guatemalan-American diaspora as a significant source of existing international patients. Similarly, Barbadian participants identified their large recreational tourism sector as creating a ready source of foreign patients with existing ties to the country. While both Barbadian and Guatemalan medical tourism proponents share a common understanding that intra-regional patients are an existing supply of international patients that should be further developed, the dominant perception driving interest in medical tourism is the proximity of the American health care market. In the short term, this supplies a vision of a large number of Americans lacking adequate health insurance willing to travel for care, while in the long term, the Affordable Care Act is seen to be an enormous potential driver of future medical tourism as it is believed that private insurers will seek to control costs by outsourcing care to providers abroad. CONCLUSIONS: Each country has some comparative advantage in medical tourism. Assumptions about a large North American patient base, however, are not supported by reliable evidence. Pursuing this market could incur costs borne by patients in their public health systems. PMID- 27717390 TI - Perip7lakin is a target for autoimmunity in asthma. AB - The role of autoimmunity targeting epithelial antigens in asthma has been suggested, in particular in non-atopic and severe asthma. Periplakin, a desmosomal component, is involved in epithelial cohesion and intracellular signaling. We detected anti-periplakin IgG antibodies in 47/260 (18 %) patients with asthma, with no association with severity or atopy. In addition, anti periplakin IgE antibodies were detected in 12 of 138 tested patients (8.7 %) and were more frequently observed in patients with than without nasal polyposis. This study identifies a new autoimmune epithelial target in asthma. Whether periplakin autoimmunity (both IgG and IgE auto-antibodies) is involved in asthma pathogenesis remains to be studied during the disease course of these patients. PMID- 27717392 TI - Risk of selection bias in randomized trials: further insight. AB - The quality of randomization is an under-appreciated facet of trial design. The present piece represents an advance in our collective understanding of how allocation concealment and randomization relate to risk of selection bias in randomized trials, and other measures are also considered. Though the overwhelming majority of the advice given is timely and correct, it is more instructive to focus on the relatively narrow sliver of advice that is incorrect (namely, that trials should not stratify by site, and that unrestricted randomization is a solution to the problem of selection bias), so it is in this context that the comments here must be understood. In no way is this intended to be a rebuttal of the excellent work we have before us. Rather, it is a refinement. PMID- 27717391 TI - The oral health of refugees and asylum seekers: a scoping review. AB - INTRODUCTION: Improving the oral health of refugees and asylum seekers is a global priority, yet little is known about the overall burden of oral diseases and their causes for this population. OBJECTIVE: To synthesize available evidence on the oral health of, and access to oral health care by this population. METHODS: Using a scoping review methodology, we retrieved 3321 records from eight databases and grey literature; 44 publications met the following inclusion criteria: empirical research focused on refugees and/or asylum seekers' oral health, published between 1990 and 2014 in English, French, Italian, Portuguese, or Spanish. Analysis included descriptive and thematic analysis, as well as critical appraisal using the Critical Appraisal Skills Programme (CASP) criteria for quantitative and qualitative studies. RESULTS: The majority of publications (86 %) were from industrialized countries, while the majority of refugees are resettled in developing countries. The most common study designs were quantitative (75 %). Overall, the majority of studies (76 %) were of good quality. Studies mainly explored oral health status, knowledge and practices; a minority (9 %) included interventions. The refugee populations in the studies showed higher burden of oral diseases and limited access to oral health care compared to even the least privileged populations in the host countries. Minimal strategies to improve oral health have been implemented; however, some have impressive outcomes. CONCLUSIONS: Oral health disparities for this population remain a major concern. More research is needed on refugees in developing countries, refugees residing in refugee camps, and interventions to bridge oral health disparities. This review has utility for policymakers, practitioners, researchers, and other stakeholders working to improve the oral health of this population. PMID- 27717393 TI - Effectiveness of a multicomponent intervention to enhance implementation of a healthy canteen policy in Australian primary schools: a randomised controlled trial. AB - BACKGROUND: The implementation of school nutrition policies, which govern the provision of food in schools, is recommended as a public health strategy to support the development of healthy dietary behaviours in school-aged children. Despite this, research internationally and in Australia indicates that few schools implement such policies. This study aims to examine whether a theoretically designed, multi-strategy intervention was effective in increasing the implementation of a healthy canteen policy in Australian primary schools. METHODS: A parallel group randomised controlled trial was conducted with all government and Catholic primary schools within one region in New South Wales, Australia who had an operational canteen that provided food to primary school aged children (5-12 years) and were not currently receiving an intervention to change their canteen practices. Schools randomised to the intervention arm received a 9-month multicomponent intervention including ongoing support, provision of resources, performance monitoring and feedback, executive support and recognition. The primary outcomes were the proportion of the schools with a canteen menu that: i) did not include 'red' or 'banned' items according to the healthy canteen policy; and ii) had more than 50 % 'green' items. The primary outcome was assessed via menu audit at baseline and follow up by dietitians blinded to group allocation. RESULTS: Fifty-three eligible schools were randomised to either the intervention or control group (28 intervention; 25 control). Analyses with 51 schools who returned school menus found that intervention schools were significantly more likely relative to control schools to have a menu without 'red' or 'banned' items (RR = 5.78 (1.45-23.05); p = 0.002) and have at least 50 % of menu items classified as green (RR = 2.03 (1.01 4.08); p = 0.03). CONCLUSIONS: This study found that a multi-component intervention was effective in improving primary schools' compliance with a healthy canteen policy. Given the lack of evidence regarding how best to support schools with implementing evidence-based policies to improve child diet, this trial for the first time provides high quality evidence to practitioners and policy makers seeking to improve nutrition policy implementation in schools. TRIAL REGISTRATION: This trial was prospectively registered with the Australian New Zealand Clinical Trials Registry ( ACTRN12614001148662 ) 30th October 2014. PMID- 27717394 TI - Musculoskeletal care pathways for adults with hip and knee pain at the interface between primary and secondary care: protocol for a systematic review. AB - BACKGROUND: Musculoskeletal (MSK) conditions are the most frequently reported chronic conditions and one of the biggest causes of disability in the UK. Given the ageing population and the impact of these problems, the demand for MSK treatment will rise. Despite reduced waiting times, MSK pathways have remained variable and inconsistent and need to be improved to meet patient needs. The aim of this systematic review is to understand the evidence for the effectiveness of current models of service delivery and care pathways for adult hip/knee pain patients accessing secondary care for specialist opinions. METHODS: MEDLINE, MEDLINE In-Process, CINAHL, Embase, PEDro, PubMed, Web of Science, Cochrane Central and HMIC databases will be searched without language restrictions for papers published from 1990 onward. Websites will be reviewed for grey literature including care pathways, policy documents and unpublished MSK research. Additionally, reference lists will be checked and citations tracked for included studies. DISCUSSION: The following evidence will be included: research considering care pathways at the intersection between primary and secondary care for adults with hip and/or knee pain in countries with an established clinical pathway. Studies considering generalised inflammatory arthropathy and post surgical care pathways will be excluded. Screening for included data will be conducted independently by two reviewers. After benchmarking, quality assessment and data extraction will be conducted by one reviewer and checked by a second. A mixed method analysis will be conducted. This systematic review will be used as part of a programme of research to identify best practice for MSK hip and knee pain care pathways. It will provide recommendations for pathway re-design to meet patient needs and ensure efficient streamlining of the patient journey. The review will combine a wide range of information sources including patient and clinician opinion, clinical guidelines, health service delivery research and stakeholder requirements. This should result in a pathway that provides better patient experience and outcomes, whilst meeting the demands placed on the NHS for high-quality evidence-based interventions with efficient use of resources. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016035510. PMID- 27717395 TI - Wild and native plants and mushrooms sold in the open-air markets of south eastern Poland. AB - BACKGROUND: The study of plants and fungi sold in open-air markets is an important part of ethnobotanical enquiry. Only few such studies were carried out in Europe. METHODS: Four of the largest open-air markets of south-eastern Poland were visited regularly, and the plants sold in them were recorded between 2013 and 2015. The aim of the study was to record native and/or wild species sold in the markets. All the plants sold in the markets were photographed regularly. In each market, 25 sellers were interviewed. Voucher specimens were collected and fungi were identified using DNA barcoding. RESULTS: Altogether, 468 species of plants were recorded, 117 of them native to south-eastern Poland - 19 only collected from the wild and 11 both wild and cultivated. Seventeen of the species are under legal protection. Most protected plants were sold from cultivation, although proper authorization procedures had not been performed. Thirty-two species of fungi were sold (including two cultivated species), all of them for culinary purposes. Two species (Lactarius quieticolor, Leccinum schistophilum) are new to the mycobiota of Poland. Ornamental plants constituted a large section of the market, and they dominated the group of native species. Food plants dominated among wild-collected plants and were sold mainly as fruits for jams, juices and alcoholic drinks, or as culinary herbs. Very few medicinal or green vegetable plants were sold. An interesting feature of the markets was the sale of Ledum palustre as an insect repellent. CONCLUSIONS: Finding two species of fungi which are new to Poland highlights the importance of DNA barcoding in ethnomycological studies. Most items in the markets are ornamental plants, or edible fruits and mushrooms. Very few medicinal plants and green vegetables are sold, which differentiates the markets from southern European ones. Such a pattern is probably the model for most central European markets. PMID- 27717396 TI - Viable phenotype of ILNEB syndrome without nephrotic impairment in siblings heterozygous for unreported integrin alpha3 mutations. AB - BACKGROUND: Integrin alpha3 (ITGA3) gene mutations are associated with Interstitial Lung disease, Nephrotic syndrome and Epidermolysis bullosa (ILNEB syndrome). To date only six patients are reported: all carried homozygous ITGA3 mutations and presented a dramatically severe phenotype leading to death before age 2 years, from multi-organ failure due to interstitial lung disease and congenital nephrotic syndrome. The involvement of skin and cutaneous adnexa was variable with sparse hair and nail dysplasia combined or not to skin lesions ranging from skin fragility to epidermolysis bullosa-like blistering. RESULTS: We report on two siblings of 13 and 9 years born to non-consanguineous healthy parents, who display growth delay, severe pulmonary fibrosis with fatigue, dyspnea on exertion and wheezing, atrophic skin with erythematosus lesions, rare eyelashes/eyebrows and pachyonychia. By exome sequencing, we identified two unreported ITGA3 missense mutations, c.373G>A (p.(G125R)) in exon 3 and c.821G>A (p.(R274Q)) in exon 6, affecting highly conserved residues in the integrin alpha3 extracellular N-terminal beta-propeller domain. Homology modelling of alpha3beta1 heterodimer fragment, encompassing the mutation sites, showed that G125 plays a pivotal structural role in the beta-propeller, while R274 might prevent the interaction between integrin and urokinase complex. CONCLUSION: We report a variant of ILNEB syndrome in two siblings differing from the previously reported patients in the lack of nephrotic impairment and survival beyond childhood. Our siblings are the first reported compound heterozygous for ITGA3 mutations; this state as well as the hypomorphic nature of their p.(R274Q) mutation likely account for their survival. PMID- 27717397 TI - Prediction of gestational age based on genome-wide differentially methylated regions. AB - BACKGROUND: We explored the association between gestational age and cord blood DNA methylation at birth and whether DNA methylation could be effective in predicting gestational age due to limitations with the presently used methods. We used data from the Norwegian Mother and Child Birth Cohort study (MoBa) with Illumina HumanMethylation450 data measured for 1753 newborns in two batches: MoBa 1, n = 1068; and MoBa 2, n = 685. Gestational age was computed using both ultrasound and the last menstrual period. We evaluated associations between DNA methylation and gestational age and developed a statistical model for predicting gestational age using MoBa 1 for training and MoBa 2 for predictions. The prediction model was additionally used to compare ultrasound and last menstrual period-based gestational age predictions. Furthermore, both CpGs and associated genes detected in the training models were compared to those detected in a published prediction model for chronological age. RESULTS: There were 5474 CpGs associated with ultrasound gestational age after adjustment for a set of covariates, including estimated cell type proportions, and Bonferroni-correction for multiple testing. Our model predicted ultrasound gestational age more accurately than it predicted last menstrual period gestational age. CONCLUSIONS: DNA methylation at birth appears to be a good predictor of gestational age. Ultrasound gestational age is more strongly associated with methylation than last menstrual period gestational age. The CpGs linked with our gestational age prediction model, and their associated genes, differed substantially from the corresponding CpGs and genes associated with a chronological age prediction model. PMID- 27717398 TI - Rapid change of fecal microbiome and disappearance of Clostridium difficile in a colonized infant after transition from breast milk to cow milk. AB - BACKGROUND: Clostridium difficile is the most common known cause of antibiotic associated diarrhea. Upon the disturbance of gut microbiota by antibiotics, C. difficile establishes growth and releases toxins A and B, which cause tissue damage in the host. The symptoms of C. difficile infection disease range from mild diarrhea to pseudomembranous colitis and toxic megacolon. Interestingly, 10 50 % of infants are asymptomatic carriers of C. difficile. This longitudinal study of the C. difficile colonization in an infant revealed the dynamics of C. difficile presence in gut microbiota. METHODS: Fifty fecal samples, collected weekly between 5.5 and 17 months of age from a female infant who was an asymptomatic carrier of C. difficile, were analyzed by 16S rRNA gene sequencing. RESULTS: Colonization switching between toxigenic and non-toxigenic C. difficile strains as well as more than 100,000-fold fluctuations of C. difficile counts were observed. C. difficile toxins were detected during the testing period in some infant stool samples, but the infant never had diarrhea. Although fecal microbiota was stable during breast feeding, a dramatic and permanent change of microbiota composition was observed within 5 days of the transition from human milk to cow milk. A rapid decline and eventual disappearance of C. difficile coincided with weaning at 12.5 months. An increase in the relative abundance of Bacteroides spp., Blautia spp., Parabacteroides spp., Coprococcus spp., Ruminococcus spp., and Oscillospira spp. and a decrease of Bifidobacterium spp., Lactobacillus spp., Escherichia spp., and Clostridium spp. were observed during weaning. The change in microbiome composition was accompanied by a gradual increase of fecal pH from 5.5 to 7. CONCLUSIONS: The bacterial groups that are less abundant in early infancy, and that increase in relative abundance after weaning, likely are responsible for the expulsion of C. difficile. PMID- 27717400 TI - Expression and regulation of ATF6alpha in the mouse uterus during embryo implantation. AB - BACKGROUND: ATF6alpha, one of the sensor proteins in the stress signaling pathway of the endoplasmic reticulum, is located in the membrane of the endoplasmic reticulum. To date, the physiological function of ATF6alpha in the process of embryo implantation has not been reported. METHODS: In this study, the expression pattern of ATF6alpha in the mouse uterus during peri-implantation and the estrous cycle was detected by real-time PCR, western blot and immunohistochemistry. RESULTS: ATF6alpha mRNA and protein levels were higher in the uterus near the implantation site on day 5 and were intensely expressed in the secondary decidual zone (SDZ) on days 7-8. In the uteri of pseudopregnant mice, ATF6alpha mRNA and protein levels were lower on day 5 than on other days. The activating blastocyst and artificial decidualization had an obvious effect of increasing the expression of ATF6alpha. In addition, the expression of ATF6alpha was affected by progesterone (P4) and estrogen (E2) in ovariectomized mice. This finding is further supported by evidence from mice during the estrous cycle. CONCLUSIONS: Thus, we have concluded that ATF6alpha may play an important role during embryo implantation and decidualization. PMID- 27717403 TI - The early bird catches the term: combining twitter and news data for event detection and situational awareness. AB - BACKGROUND: Twitter updates now represent an enormous stream of information originating from a wide variety of formal and informal sources, much of which is relevant to real-world events. They can therefore be highly useful for event detection and situational awareness applications. RESULTS: In this paper we apply customised filtering techniques to existing bio-surveillance algorithms to detect localised spikes in Twitter activity, showing that these correspond to real events with a high level of confidence. We then develop a methodology to automatically summarise these events, both by providing the tweets which best describe the event and by linking to highly relevant news articles. This news linkage is accomplished by identifying terms occurring more frequently in the event tweets than in a baseline of activity for the area concerned, and using these to search for news. We apply our methods to outbreaks of illness and events strongly affecting sentiment and are able to detect events verifiable by third party sources and produce high quality summaries. CONCLUSIONS: This study demonstrates linking event detection from Twitter with relevant online news to provide situational awareness. This builds on the existing studies that focus on Twitter alone, showing that integrating information from multiple online sources can produce useful analysis. PMID- 27717401 TI - Adoptive transfer of M2 macrophages reduces neuropathic pain via opioid peptides. AB - BACKGROUND: During the inflammation which occurs following nerve damage, macrophages are recruited to the site of injury. Phenotypic diversity is a hallmark of the macrophage lineage and includes pro-inflammatory M1 and anti inflammatory M2 populations. Our aim in this study was to investigate the ability of polarized M0, M1, and M2 macrophages to secrete opioid peptides and to examine their relative contribution to the modulation of neuropathic pain. METHODS: Mouse bone marrow-derived cells were cultured as unstimulated M0 macrophages or were stimulated into an M1 phenotype using lipopolysaccharide and interferon-gamma or into an M2 phenotype using interleukin-4. The macrophage phenotypes were verified using flow cytometry for surface marker analysis and cytokine bead array for cytokine profile assessment. Opioid peptide levels were measured by radioimmunoassay and enzyme immunoassay. As a model of neuropathic pain, a chronic constriction injury (CCI) of the sciatic nerve was employed. Polarized M0, M1, and M2 macrophages (5 * 105 cells) were injected perineurally twice, on days 14 and 15 following CCI or sham surgery. Mechanical and heat sensitivity were measured using the von Frey and Hargreaves tests, respectively. To track the injected macrophages, we also transferred fluorescently stained polarized cells and analyzed the surface marker profile of endogenous and injected cells in the nerves ex vivo. RESULTS: Compared to M0 and M1 cells, M2 macrophages contained and released higher amounts of opioid peptides, including Met-enkephalin, dynorphin A (1-17), and beta-endorphin. M2 cells transferred perineurally at the nerve injury site reduced mechanical, but not heat hypersensitivity following the second injection. The analgesic effect was reversed by the perineurally applied opioid receptor antagonist naloxone methiodide. M2 cells did not affect sensitivity following sham surgery. Neither M0 nor M1 cells altered mechanical and heat sensitivity in CCI or sham-operated animals. Tracing the fluorescently labeled M0, M1, and M2 cells ex vivo showed that they remained in the nerve and preserved their phenotype. CONCLUSIONS: Perineural transplantation of M2 macrophages resulted in opioid-mediated amelioration of neuropathy-induced mechanical hypersensitivity, while M1 macrophages did not exacerbate pain. Therefore, rather than focusing on macrophage-induced pain generation, promoting opioid-mediated M2 actions may be more relevant for pain control. PMID- 27717402 TI - Timing of in utero malaria exposure influences fetal CD4 T cell regulatory versus effector differentiation. AB - BACKGROUND: In malaria-endemic areas, the first exposure to malaria antigens often occurs in utero when the fetal immune system is poised towards the development of tolerance. Children exposed to placental malaria have an increased risk of clinical malaria in the first few years of life compared to unexposed children. Recent work has suggested the potential of pregnancy-associated malaria to induce immune tolerance in children living in malaria-endemic areas. A study was completed to evaluate the effect of malaria exposure during pregnancy on fetal immune tolerance and effector responses. METHODS: Using cord blood samples from a cohort of mother-infant pairs followed from early in pregnancy until delivery, flow cytometry analysis was completed to assess the relationship between pregnancy-associated malaria and fetal cord blood CD4 and dendritic cell phenotypes. RESULTS: Cord blood FoxP3+ Treg counts were higher in infants born to mothers with Plasmodium parasitaemia early in pregnancy (12-20 weeks of gestation; p = 0.048), but there was no association between Treg counts and the presence of parasites in the placenta at the time of delivery (by loop-mediated isothermal amplification (LAMP); p = 0.810). In contrast, higher frequencies of activated CD4 T cells (CD25+FoxP3-CD127+) were observed in the cord blood of neonates with active placental Plasmodium infection at the time of delivery (p = 0.035). This population exhibited evidence of effector memory differentiation, suggesting priming of effector T cells in utero. Lastly, myeloid dendritic cells were higher in the cord blood of infants with histopathologic evidence of placental malaria (p < 0.0001). CONCLUSION: Together, these data indicate that in utero exposure to malaria drives expansion of both regulatory and effector T cells in the fetus, and that the timing of this exposure has a pivotal role in determining the polarization of the fetal immune response. PMID- 27717399 TI - An epigenetic clock for gestational age at birth based on blood methylation data. AB - BACKGROUND: Gestational age is often used as a proxy for developmental maturity by clinicians and researchers alike. DNA methylation has previously been shown to be associated with age and has been used to accurately estimate chronological age in children and adults. In the current study, we examine whether DNA methylation in cord blood can be used to estimate gestational age at birth. RESULTS: We find that gestational age can be accurately estimated from DNA methylation of neonatal cord blood and blood spot samples. We calculate a DNA methylation gestational age using 148 CpG sites selected through elastic net regression in six training datasets. We evaluate predictive accuracy in nine testing datasets and find that the accuracy of the DNA methylation gestational age is consistent with that of gestational age estimates based on established methods, such as ultrasound. We also find that an increased DNA methylation gestational age relative to clinical gestational age is associated with birthweight independent of gestational age, sex, and ancestry. CONCLUSIONS: DNA methylation can be used to accurately estimate gestational age at or near birth and may provide additional information relevant to developmental stage. Further studies of this predictor are warranted to determine its utility in clinical settings and for research purposes. When clinical estimates are available this measure may increase accuracy in the testing of hypotheses related to developmental age and other early life circumstances. PMID- 27717404 TI - Composition and cytotoxic and antioxidant activities of the oil of Piper aequale Vahl. AB - BACKGROUND: Piper aequale Vahl is a small shrub that grows in the shadow of large trees in the Carajas National Forest, Municipality of Parauapebas, Para state, Brazil. The local people have used the plant against rheumatism and inflammation. METHODS: The essential oil of the aerial parts was extracted and analyzed by GC and GC-MS. The MTT colorimetric assay was used to measuring the cytotoxic activity of the oil against human cancer lines. The determination of antioxidant activity of the oil was conducted by DPPH radical scavenging assay. RESULTS: The main constituents were delta-elemene (18.92 %), beta-pinene (15.56 %), alpha pinene (12.57 %), cubebol (7.20 %), beta-atlantol (5.87 %), and bicyclogermacrene (5.51 %), totalizing 65.63 % of the oil. The oil displayed a strong in vitro cytotoxic activity against the human cancer cell lines HCT-116 (colon) and ACP03 (gastric) with IC50values of 8.69 MUg/ml and 1.54 MUg/ml, respectively. The oil has induced the apoptosis in a gastric cancer cells in all tested concentration (0.75-3.0 MUg/ml), after 72 h of treatment, when compared to negative control (p < 0.001). Also, the oil showed a significant antioxidant activity (280.9 +/- 22.2 mg TE/ml), when analyzed as Trolox equivalent, and a weak acetylcholinesterase inhibition, with a detection limit of 100 ng, when compared to the physostigmine standard (1.0 ng). CONCLUSION: The higher cell growth inhibition induced by the oil of P. aequale is probably due to its primary terpene compounds, which were previously reported in the proliferation inhibition, in stimulation of apoptosis and induction of cell cycle arrest in malignant cells. PMID- 27717405 TI - Group schema therapy versus group cognitive behavioral therapy for social anxiety disorder with comorbid avoidant personality disorder: study protocol for a randomized controlled trial. AB - BACKGROUND: Social anxiety disorder (SAD) with comorbid avoidant personality disorder (APD) has a high prevalence and is associated with serious psychosocial problems and high societal costs. When patients suffer from both SAD and APD, the Dutch multidisciplinary guidelines for personality disorders advise offering prolonged cognitive behavioral therapy (CBT). Recently there is increasing evidence for the effectiveness of schema therapy (ST) for personality disorders such as borderline personality disorder and cluster C personality disorders. Since ST addresses underlying personality characteristics and maladaptive coping strategies developed in childhood, this treatment might be particularly effective for patients with SAD and comorbid APD. To our knowledge, there are no studies comparing CBT with ST in this particular group of patients. This superiority trial aims at comparing the effectiveness of these treatments. As an additional goal, predictors and underlying mechanisms of change will be explored. METHODS/DESIGN: The design of the study is a multicentre two-group randomized controlled trial (RCT) in which the treatment effect of group cognitive behavioral therapy (GCBT) will be compared to that of group schema therapy (GST) in a semi-open group format. A total of 128 patients aged 18-65 years old will be enrolled. Patients will receive 30 sessions of GCBT or GST during a period of approximately 9 months. Primary outcome measures are the Liebowitz Social Anxiety Scale Self-Report (LSAS-SR) for social anxiety disorder and the newly developed Avoidant Personality Disorder Severity Index (AVPDSI) for avoidant personality disorder. Secondary outcome measures are the MINI section SAD, the SCID-II section APD, the Schema Mode Inventory (SMI-2), the Inventory of Depressive Symptomatology Self-Report (IDS-SR), the World Health Organization Quality of Life-BREF (WHOQOL-BREF), the Difficulties in Emotion Regulation Scale (DERS), the Rosenberg Self-Esteem Scale (RSES) and the Acceptance and Action Questionnaire (AAQ-II). Data will be collected at the start, halfway and at the end of the treatment, followed by measurements at 3, 6 and 12 months post-treatment. DISCUSSION: The trial will increase our knowledge on the effectiveness and applicability of both treatment modalities for patients suffering from both diagnoses. TRIAL REGISTRATION: Dutch Trial Register: NTR3921 . Registered on 25 March 2013. PMID- 27717406 TI - Mosquito-borne heartworm Dirofilaria immitis in dogs from Australia. AB - BACKGROUND: Heartworm (Dirofilaria immitis) in dogs is considered endemic in Australia, but the clinical heartworm disease caused by the heartworm is rare and prevalence is low. The mainstream prevention of the heartworm is based on macrocyclic lactone (ML) administration. The aim of this study was to confirm endemism of the heartworm under current Australian conditions using a cohort of recent microfilaria-positive dogs which were on variable heartworm prevention. METHODS: A hotspot of canine heartworm antigen-positive and microfilaria-positive dogs has been detected recently in Queensland, Australia. Blood samples from 39 dogs from Queensland and two dogs from New South Wales were investigated for canine filarioids. Rapid antigen diagnostic tests capable of detection of D. immitis and real-time PCR for quantification and differentiation between D. immitis from Acanthocheilonema reconditum with quantification of microfilariae in canine blood samples, together with D. immitis specific real-time PCR assay, were applied to microfilaria-positive dogs. The P-glycoprotein genotype was determined to test whether Australian-sourced heartworm shared the same genetic markers as those suspected of ML-resistance in North America. RESULTS: Only D. immitis was detected in the samples from Queensland and New South Wales, Australia. Using high resolution melt real-time PCR and D. immitis specific real-time PCR, the calculated microfilaria concentration ranged from 1 to 44,957 microfilariae/ml and from 7 to 60,526 microfilariae/ml, respectively. DNA sequencing of the PCR products confirmed D. immitis. Fifteen of the examined dogs were on putative, rigorous ML prevention. For the remaining dogs, compliance with heartworm prevention was unknown or reported as inconsistent. Wild-type genotype AA-GG of the P-glycoprotein locus of D. immitis sequence has been obtained for three blood samples. Due to the incomplete history, any suggestion of a loss of efficacy of MLs must be treated as 'remotely possible'. In the immediate future, records of preventative administration and annual antigen testing would be required to determine any problems with the efficacy of preventatives. CONCLUSIONS: The prevalence of canine heartworm in Australia remains poorly understood. It is generally assumed to be low by veterinary practitioners. The localised increase in the study area confirms endemism of canine heartworm and a requirement for ongoing vigilance through annual heartworm testing to better understand the changing distribution of canine heartworm, client compliance, as well as to detect any change in ML-susceptibility. PMID- 27717407 TI - A feasibility study of the clinical effectiveness and cost-effectiveness of individual cognitive behavioral therapy for panic disorder in a Japanese clinical setting: an uncontrolled pilot study. AB - BACKGROUND: In Japan, cognitive behavioral therapy (CBT) for panic disorder (PD) is not well established. Therefore, a feasibility study of the clinical effectiveness and cost-effectiveness of CBT for PD in a Japanese clinical setting is urgently required. This was a pilot uncontrolled trial and the intervention consisted of a 16-week CBT program. The primary outcome was Panic Disorder Severity Scale (PDSS) scores. Quality of life was assessed using the EuroQol's EQ 5D questionnaire. Assessments were conducted at baseline, 8 weeks, and at the end of the study. Fifteen subjects completed outcome measures at all assessment points. RESULTS: At post-CBT, the mean reduction in PDSS scores from baseline was -6.6 (95 % CI 3.80 to -9.40, p < 0.001) with a Cohen's d = 1.77 (95 % CI 0.88 2.55). Ten (66.7 %) participants achieved a 40 % or greater reduction in PDSS. By calculating areas under the curve for EQ-5D index changes, we estimated that patients gained a minimum of 0.102 QALYs per 1 year due to the CBT. CONCLUSIONS: This study demonstrated that individual CBT for PD may be useful in Japanese clinical settings but further randomized control trials are needed.

AB - BACKGROUND: Quail eggs as a food item have recently been introduced into the diet of some Cameroonians. These eggs are being sold in local markets, but with many unfounded health claims. One claim is that quail eggs can reduce blood glucose levels in diabetics. It was therefore necessary to evaluate the effect of consuming quail eggs on blood glucose levels, lipid profiles, and oxidative stress parameters in diabetes-induced rats. METHODS: Twenty Wistar rats weighing, on average, 250 g were divided into four groups of five rats each. Group 1 consisted of rats with normal blood glucose, and the other three groups (2, 3, and 4) consisted of diabetes-induced rats achieved by intravenous injection of streptozotocin. During 16 days, rats in groups 1 and 2 received distilled water; and rats in groups 3 and 4 received quail and chicken eggs, respectively, with gastroesophageal probe at a dose of 1 mL/200 g body weight. Fasting blood glucose levels were determined in all the groups on the 1st, 7th, 14th, and 17th days after induction of diabetes. On the 17th day, the fasting rats were sacrificed, and blood and liver samples were collected for biochemical analyses. RESULTS: In 17 days, the consumption of quail and chicken eggs had no effect on blood glucose levels of diabetic rats. Total cholesterol levels were higher in groups 3 (75.59 mg/dL) and 4 (59.41 mg/dL) compared to group 2 (55.67 mg/dl), although these differences were not significant (all p>0.05). Triglyceride levels were significantly higher (p<0.05) in groups 3 (106.52 mg/dL) and 4 (109.65 mg/dL) compared to group 2 (65.82 mg/dL). Quail eggs had no effect on oxidative stress parameters (malondialdehyde, hydroperoxides, and catalase). CONCLUSIONS: The consumption of quail eggs by diabetic rats at the tested dose had no effect on blood glucose level and oxidative stress parameters and may have a negative effect on lipid profile. PMID- 27717408 TI - The structure and diversity of human, animal and environmental resistomes. AB - BACKGROUND: Antibiotic resistance genes (ARGs) are widespread but cause problems only when present in pathogens. Environments where selection and transmission of antibiotic resistance frequently take place are likely to be characterized by high abundance and diversity of horizontally transferable ARGs. Large-scale quantitative data on ARGs is, however, lacking for most types of environments, including humans and animals, as is data on resistance genes to potential co selective agents, such as biocides and metals. This paucity prevents efficient identification of risk environments. RESULTS: We provide a comprehensive characterization of resistance genes, mobile genetic elements (MGEs) and bacterial taxonomic compositions for 864 metagenomes from humans (n = 350), animals (n = 145) and external environments (n = 369), all deeply sequenced using Illumina technology. Environment types showed clear differences in both resistance profiles and bacterial community compositions. Human and animal microbial communities were characterized by limited taxonomic diversity and low abundance and diversity of biocide/metal resistance genes and MGEs but a relatively high abundance of ARGs. In contrast, external environments showed consistently high taxonomic diversity which in turn was linked to high diversity of both biocide/metal resistance genes and MGEs. Water, sediment and soil generally carried low relative abundance and few varieties of known ARGs, whereas wastewater/sludge was on par with the human gut. The environments with the largest relative abundance and/or diversity of ARGs, including genes encoding resistance to last resort antibiotics, were those subjected to industrial antibiotic pollution and a limited set of deeply sequenced air samples from a Beijing smog event. CONCLUSIONS: Our study identifies air and antibiotic-polluted environments as under-investigated transmission routes and reservoirs for antibiotic resistance. The high taxonomic and genetic diversity of external environments supports the hypothesis that these also form vast sources of unknown resistance genes, with potential to be transferred to pathogens in the future. PMID- 27717409 TI - A systematic review of measures of HIV/AIDS stigma in paediatric HIV-infected and HIV-affected populations. AB - INTRODUCTION: HIV-related stigma impacts the quality of life and care management of HIV-infected and HIV-affected individuals, but how we measure stigma and its impact on children and adolescents has less often been described. METHODS: We conducted a systematic review of studies that measured HIV-related stigma with a quantitative tool in paediatric HIV-infected and HIV-affected populations. RESULTS AND DISCUSSION: Varying measures have been used to assess stigma in paediatric populations, with most studies utilizing the full or variant form of the HIV Stigma Scale that has been validated in adult populations and utilized with paediatric populations in Africa, Asia and the United States. Other common measures included the Perceived Public Stigma Against Children Affected by HIV, primarily utilized and validated in China. Few studies implored item validation techniques with the population of interest, although scales were used in a different cultural context from the origin of the scale. CONCLUSIONS: Many stigma measures have been used to assess HIV stigma in paediatric populations, globally, but few have implored methods for cultural adaptation and content validity. PMID- 27717411 TI - Food as a tool for learning in everyday activities at preschool - an exploratory study from Sweden. AB - BACKGROUND: There is a need for research both in relation to food education at preschools and in relation to how the individual teacher can handle and relate to the many different scientific facts and paradigms that are prevalent in relation to food, health, and a sustainable lifestyle. OBJECTIVE: The aim of this study was to explore the experiences and meanings that preschool teachers associate with involving food as a tool for learning in planned educational activities. DESIGN: An exploratory study was conducted in 14 preschools with 131 teachers. Twenty semi-structured individual or group interviews with 45 preschool staff were conducted, and 10 interviews were selected for analysis. RESULTS: According to participants, both children and teachers developed a sensory language; children became more positive towards tasting and teachers discovered new possibilities for interdisciplinary work. However, the results also show that an allowing system, with both an interested and confident teacher who recognises the competent child and a supportive organisation, is needed in order to make food a meaningful tool for learning in preschool. DISCUSSION: According to previous studies, food has the potential to play an important part in everyday activities at preschool, both in planned educational activities as well as at meal situations. Our results imply that a holistic understanding of food in preschool is required for long-term work with food as a natural part of the everyday activities. CONCLUSION: The results imply that it is fun and meaningful for both children and teachers, and quite possible, to work with food as a tool for learning in everyday activities at preschool. In order to include food as a way to work with the preschool curriculum for a sustainable lifestyle, an allowing system is needed. PMID- 27717412 TI - Benefits of pharmacist-led flu vaccination services in community pharmacy. AB - Seasonal influenza is a major cause of excess winter deaths and increased hospital admissions. There is a high level of economic burden associated with the infection. Although vaccination targets have been set to tackle this international issue, many countries struggle to reach these coverage targets for their at-risk populations using traditional delivery methods. Traditional providers include family doctors and nurses; however, pharmacist-led influenza vaccination has become a more commonly utilised aid to support vaccination targets. Community pharmacies are convenient and widely accessible and evaluations consistently demonstrate that patients are satisfied with pharmacist led vaccinations. Allowing community pharmacists to administer influenza vaccination as an alternative option for delivery helps to increase the coverage rate of vaccination. In addition, commissioning community pharmacists to provide this service has been shown to contribute to achieving targets for those at-risk. Pharmacist-led influenza vaccination services can create value for payors and reduce pressure on health systems. This review aims to demonstrate the success of pharmacy-led influenza vaccinations, and the impact it has had in driving up immunisation rates within other countries. Experiences of countries such as England, Portugal and the United States provide evidence to demonstrate the benefit to both the patient and the health system. PMID- 27717413 TI - Implementation of flu vaccination in community pharmacies: Understanding the barriers and enablers. AB - Improving influenza vaccination coverage has been, and still remains a challenge internationally. There are now many examples where countries have pursued a pharmacist-led influenza vaccination service in order to enhance vaccination coverage of at-risk populations. England, Portugal and the United States are successful examples where their experience implementing this service can now be explored retrospectively and learnt from. This review aims to provide evidence to help overcome barriers to commissioning and implementation of such services in countries new to the experience. Implementation is influenced by differing regulatory frameworks underpinning the provision of pharmacist-led influenza vaccination, methods of remuneration, training, and operating procedures. Practical aspects such as the facilities required, how patient records are maintained and how patients and other healthcare professionals are engaged also have an impact. These examples illustrate how community pharmacists can be trained to deliver influenza vaccinations safely, and coupled with their accessibility and convenience, can provide a complementary service to that already provided by family doctors and nurses to deliver influenza vaccinations for the benefit of patients. PMID- 27717414 TI - Overview of Laboratory Testing and Clinical Presentations of Complement Deficiencies and Dysregulation. AB - Historically, complement disorders have been attributed to immunodeficiency associated with severe or frequent infection. More recently, however, complement has been recognized for its role in inflammation, autoimmune disorders, and vision loss. This paradigm shift requires a fundamental change in how complement testing is performed and interpreted. Here, we provide an overview of the complement pathways and summarize recent literature related to hereditary and acquired angioedema, infectious diseases, autoimmunity, and age-related macular degeneration. The impact of complement dysregulation in atypical hemolytic uremic syndrome, paroxysmal nocturnal hemoglobinuria, and C3 glomerulopathies is also described. The advent of therapeutics such as eculizumab and other complement inhibitors has driven the need to more fully understand complement to facilitate diagnosis and monitoring. In this report, we review analytical methods and discuss challenges for the clinical laboratory in measuring this complex biochemical system. PMID- 27717415 TI - Monitoring Oxygen Status. AB - Although part of a common "blood gas" test panel with pH and pCO2, the pO2, %O2Hb, and related parameters are independently used to detect and monitor oxygen deficits from a variety of causes. Measurement of blood gases and cooximetry may be done by laboratory analyzers, point of care testing, noninvasive pulse oximetry, and transcutaneous blood gases. The specimen type and mode of monitoring oxygenation that are chosen may be based on a combination of urgency, practicality, clinical need, and therapeutic objectives. Because oxygen concentrations in blood are extremely labile, there are several highly important preanalytical practices necessary to prevent errors in oxygen and cooximetry results. Effective utilization of oxygen requires binding by hemoglobin in the lungs, transport in the blood, and release to tissues, where cellular respiration occurs. Hydrogen ion (pH), CO2, temperature, and 2,3-DPG all play important roles in these processes. Additional measurements and calculations are often used to interpret and locate the cause and source of an oxygen deficit. These include the Hb concentration, Alveolar-arterial pO2 gradient, pO2:FIO2 ratio, oxygenation index, O2 content and O2 delivery, and pulmonary dead space and intrapulmonary shunting. The causes of hypoxemia will be covered and, to illustrate how the oxygen parameters are used clinically in the diagnosis and management of patients with abnormal oxygenation, two clinical cases will be presented and described. PMID- 27717416 TI - Microvesicles in Autoimmune Diseases. AB - During apoptosis or activation, cells can release a subcellular structure, called a membrane microvesicle (also known as microparticle) into the extracellular environment. Microvesicles bud-off as a portion of cell membrane with its associated proteins and lipids surrounding a cytosolic core that contains intracellular proteins, lipids, and nucleic acids (DNA, RNA, siRNA, microRNA, lncRNA). Biologically active molecules on the microvesicle surface and encapsulated within can act on recipient cells as a novel mode of intercellular communication. Apoptosis has long been known to be involved in the development of diseases of autoimmunity. Abnormally persistent microvesicles, particularly apoptotic microvesicles, can accelerate autoimmune responses locally in specific organs and tissues as well as systemically. In this review, we focus on studies implicating microvesicles in the pathogenesis of autoimmune diseases and their complications. PMID- 27717417 TI - Tandem Mass Spectrometry of Sphingolipids: Applications for Diagnosis of Sphingolipidoses. AB - In recent years, mass spectrometry (MS) has become the dominant technology in lipidomic analysis. It is widely used in diagnosis and research of lipid metabolism disorders including those characterized by impairment of lysosomal functions and storage of nondegraded-degraded substrates. These rare diseases, which include sphingolipidoses, have severe and often fatal clinical consequences. Modern MS methods have contributed significantly to achieve a definitive diagnosis, which is essential in clinical practice to begin properly targeted patient care. Here we summarize MS and tandem MS methods used for qualitative and quantitative analysis of sphingolipids (SL) relative to the diagnostic process for sphingolipidoses and studies focusing on alterations in cell functions due to these disorders. This review covers the following topics: Tandem MS is sensitive and robust in determining the composition of sphingolipid classes in various biological materials. Its ability to establish SL metabolomic profiles using MS bench-top analyzers, significantly benefits the first stages of a diagnosis as well as metabolic studies of these disorders. It can thus contribute to a better understanding of the biological significance of SL. PMID- 27717418 TI - Advances in Blood Typing. AB - The clinical importance of blood group antigens relates to their ability to evoke immune antibodies that are capable of causing hemolysis. The most important antigens for safe transfusion are ABO and D (Rh), and typing for these antigens is routinely performed for patients awaiting transfusion, prenatal patients, and blood donors. Typing for other blood group antigens, typically of the Kell, Duffy, Kidd, and MNS blood groups, is sometimes necessary, for patients who have, or are likely to develop antibodies to these antigens. The most commonly used typing method is serological typing, based on hemagglutination reactions against specific antisera. This method is generally reliable and practical for routine use, but it has certain drawbacks. In recent years, molecular typing has emerged as an alternative or supplemental typing method. It is based on detecting the polymorphisms and mutations that control the expression of blood group antigens, and using this information to predict the probable antigen type. Molecular typing methods are useful when traditional serological typing methods cannot be used, as when a patient has been transfused and the sample is contaminated with red blood cells from the transfused blood component. Moreover, molecular typing methods can precisely identify clinically significant variant antigens that cannot be distinguished by serological typing; this capability has been exploited for the resolution of typing discrepancies and shows promise for the improved transfusion management of patients with sickle cell anemia. Despite its advantages, molecular typing has certain limitations, and it should be used in conjunction with serological methods. PMID- 27717419 TI - Autoimmunity in Crohn's Disease-A Putative Stratification Factor of the Clinical Phenotype. AB - Inflammation in inflammatory bowel diseases (IBD) has been linked to a loss of tolerance to self-antigens suggesting the existence of autoantibodies in specific disease phenotypes. However, the lack of clearly defined autoantigenic targets has slowed down research. Genome-wide association studies have identified an impressive number of immune-related susceptibility loci for IBD with no clearly discernible pattern among them. Growing evidence supports the hypothesis that innate immune responses to a low-diversity and impaired gut microbiota may be of key importance in initiating and perpetuating chronic inflammation in IBD. Increasing evidence suggests that reduced microbial diversity and microbial mucosal epithelium interaction (including adhesion and clearance) are critically involved in IBD pathogenesis. Along these lines the discovery of autoantigenic targets in Crohn's disease (CD) has refocused research in IBD on the possible role of autoimmune responses. The identification of the major zymogen granule membrane glycoprotein 2 (GP2) as an autoantigen in CD patients and its proposed role in the sensing of the microbiota lends credence to this trend. Loss of tolerance to GP2 occurs in up to 40% of patients with CD. Corresponding autoantibodies appear to be associated with distinct disease courses (types or phenotypes) in CD. Here, we critically review autoantibodies in CD for their impact on clinical practice and future IBD research. The immunomodulatory role of GP2 in innate and adaptive intestinal immunity is also discussed. PMID- 27717421 TI - Omalizumab in the Treatment of Chronic Inducible Urticaria. AB - Omalizumab is a recombinant humanized monoclonal antibody that inhibits immunoglobulin E. It has been approved for the treatment of severe asthma and chronic spontaneous urticaria refractory to other treatments. Its use in the management of chronic inducible urticaria (a type triggered by certain stimuli) is still considered off-label, although this use has been discussed in some consensus papers. This review brings together case reports and case series describing the use of omalizumab to treat chronic inducible urticaria. We analyze the most important aspects of the cases and the outcomes reported. The results seem to position omalizumab as a potentially effective, safe treatment alternative in some cases of chronic inducible urticaria. PMID- 27717422 TI - Left Ventricular Assist Device Design Reduces von Willebrand Factor Degradation: A Comparative Study Between the HeartMate II and the EVAHEART Left Ventricular Assist System. AB - BACKGROUND: Supraphysiologic shear stress from continuous-flow left ventricular assist devices (LVADs) accelerates von Willebrand factor (vWF) degradation and predisposes patients to nonsurgical bleeding. It is unknown whether unique design characteristics of LVADs differentially affect vWF degradation. We tested the hypothesis that the centrifugal-flow EVAHEART (Evaheart, Houston, TX) left ventricular assist system (LVAS), which was designed to minimize shear stress (low operational revolutions per minute [rpm], larger flow gaps, low shear stress, flat H-Q curve), reduced vWF degradation versus the axial-flow HeartMate II (Thoratec, Pleasanton, CA) LVAD. METHODS: Whole human blood was obtained from volunteer donors (n = 22). Blood was circulated for 12 hours in mock circulatory loops through a HeartMate II (n = 10; 11,400 rpm, 6.3 +/- 0.8 L/min, 76 +/- 2 mm Hg) or an EVAHEART LVAS (n = 12; 2,300 rpm, 5.7 +/- 0.1 L/min, 80 +/- 1 mm Hg). vWF degradation was characterized with electrophoresis and immunoblotting for large vWF multimers and 11 vWF degradation fragments. RESULTS: The HeartMate II eliminated large vWF multimers and significantly (p < 0.05) increased 10 of 11 vWF degradation fragments at 6 and 12 hours. The increase was approximately 2.0 fold at 6 hours and 2.2-fold at 12 hours. In contrast, the EVAHEART LVAS modestly reduced large vWF multimers and significantly increased 5 of 11 and 8 of 11 vWF degradation fragments at 6 and 12 hours, respectively. The increase was approximately 1.5-fold at 6 hours and 1.7-fold at 12 hours. The EVAHEART LVAS caused significantly less degradation (p < 0.01) than the HeartMate II of the 140 kDa vWF fragment (cleavage product of ADAMTS-13, the vWF protease). CONCLUSIONS: The EVAHEART LVAS caused significantly less vWF degradation than the HeartMate II in a mock circulatory loop with whole human blood. LVAD design features may minimize vWF degradation. These data may inform the design and operation of next generation LVADs to minimize blood trauma. PMID- 27717423 TI - Conduction Disorders After Sutureless Aortic Valve Replacement. AB - BACKGROUND: Sutureless self-expandable aortic bioprostheses rely on radial forces for stabilization, raising concern that these devices may increase the risk of postoperative conduction disease. The purpose of this study was to determine the incidence of conduction disorders after sutureless aortic valve replacement (AVR) with the Perceval S (Sorin Group, Saluggia, Italy) bioprosthesis. METHODS: Between June 2011 and March 2013, 108 consecutive patients underwent sutureless AVR with the Perceval S prosthesis. Six patients (6%) had a permanent pacemaker (PPM) preoperatively and were excluded from the present study. Mean electrocardiographic follow-up was 14.6 +/- 6.0 months. RESULTS: Mean age was 79.2 +/- 4.8 years (52% female). During the postoperative period, 34 patients (34%) had first-degree atrioventricular block, 2 (2%) had Mobitz-II atrioventricular block, and 16 (16%) had complete atrioventricular block. New onset left bundle branch block and right bundle branch block were observed in 33 patients (33%) and 22 patients (22%), respectively. Inhospital postoperative PPM implantation was required in 23 patients (23%). Preoperative aortic valve area, age more than 85 years, and preoperative right bundle branch block were found to be independently associated with inhospital PPM implantation or new-onset postoperative conduction disorder. At follow-up, 3 more patients (3%) underwent PPM implantation. The cumulative incidences of PPM dependency and ventricular pacing more than 25% of the time were 18% +/- 11% and 21% +/- 10%, respectively, at 18 months. CONCLUSIONS: In the present study, the postoperative PPM implantation rate (23%) after sutureless AVR with the Perceval S prosthesis was high. Surgical strategies aimed at mitigating this risk should be further investigated. PMID- 27717424 TI - The Role of Echocardiography and Intracardiac Exploration in the Evaluation of Candidacy for Biventricular Repair in Patients With Borderline Left Heart Structures. AB - BACKGROUND: Predictors for single ventricle palliation (SVP) or successful biventricular repair (BVR) in patients with borderline left-side heart structures are not well defined. The goal was to evaluate the role of echocardiography and intracardiac exploration in determining feasibility of BVR. METHODS: All neonates surgically treated from 1995 to 2015 with mitral valve (MV), aortic valve, or left ventricle end-diastolic dimension z score of -2 or less for whom management was controversial were included. Data were analyzed using Fisher's exact test, Kruskal-Wallis test, and Kaplan-Meier analysis. RESULTS: The cohort consisted of 42 patients: 7 SVP (17%) and 35 BVR (83%). Median follow-up was 7 years (range, 6 months to 18 years). Intracardiac exploration was performed in 29 patients (69%). There was poor correlation between echocardiographic and intraoperative MV measurements (intraclass correlation coefficient 0.14). Preoperative echocardiography significantly underestimated MV size in 14 patients (54%). Two BVR patients were converted to SVP, and 4 (including 1 converted patient) had cardiac-related deaths. All patients with MV greater than 8 mm on preoperative echocardiography had successful BVR. An intraoperative MV less than 8 mm and an abnormal subvalvar apparatus was present in 5 of 6 SVP (83%) and 3 of 3 (100%) failed BVR patients who had intracardiac exploration, and in only 1 of 20 successful BVR patients (5%) who had an intracardiac exploration. CONCLUSIONS: The decision to proceed to BVR in patients with borderline left-side heart structures should not rely strictly on echocardiographic measurements. Intracardiac exploration of the MV and subvalvar apparatus is useful before committing a patient to SVP. Patients with low MV z scores, especially those with a normal subvalvar apparatus, may undergo BVR with good outcomes. PMID- 27717425 TI - The Association Between Urine Output, Creatinine Elevation, and Death. AB - BACKGROUND: Acute kidney injury can be defined by a fall in urine output, and urine output criteria may be more sensitive in identifying acute kidney injury than traditional serum creatinine criteria. However, as pointed out in the Kidney Disease Improving Global Outcome guidelines, the association of urine output with subsequent creatinine elevations and death is poorly characterized. The purpose of this study was to determine what degrees of reduced urine output are associated with subsequent creatinine elevation and death. METHODS: This was a retrospective cohort study of adult patients (age >=18 years) cared for in a cardiovascular intensive care unit after undergoing cardiac operations in a tertiary care university medical center. All adult patients who underwent cardiac operations and were not receiving dialysis preoperatively were studied. The development of acute kidney injury was defined as an increase in creatinine of more than 0.3 mg/dL or by more than 50% above baseline by postoperative day 3. RESULTS: Acute kidney injury developed in 1,061 of 4,195 patients (25%). Urine output had moderate discrimination in predicting subsequent acute kidney injury (C statistic = .637 +/- .054). Lower urine output and longer duration of low urine output were associated with greater odds of developing acute kidney injury and death. CONCLUSIONS: We found that there is similar accuracy in using urine output corrected for actual, ideal, or adjusted weight to discriminate future acute kidney injury by creatinine elevation and recommend using actual weight for its simplicity. We also found that low urine output is associated with subsequent acute kidney injury and that the association is greater for lower urine output and for low urine output of longer durations. Low urine output (<0.2 mL . kg-1 . h-1), even in the absence of acute kidney injury by creatinine elevation, is independently associated with mortality. PMID- 27717426 TI - The Racial Paradox in Multiarterial Conduit Utilization for Coronary Artery Bypass Grafting. AB - BACKGROUND: It has been established that outcomes for black patients undergoing coronary artery bypass graft surgery (CABG) are inferior to those of their white counterparts. The purpose of this study was to determine (1) whether rates of multiarterial grafting are different among black patients and white patients, and (2) whether racial differences exist in postoperative outcomes after accounting for grafting strategy. METHODS: A retrospective review of black patients (n = 2,810) and white patients (n = 13,569) who underwent isolated, primary CABG from January 2002 to June 2014 at a US academic institution was performed. A modified predicted risk of mortality (M-PROM) score was calculated for each patient using all The Society of Thoracic Surgeons variables for CABG excluding race. Multivariable linear, logistic, and Cox regression analyses were used to assess between-group differences, adjusted for M-PROM. RESULTS: Overall, 16,379 patients underwent CABG, and 2,441 (14.9%) received more than one arterial graft. When adjusted for M-PROM, the odds of blacks undergoing multiarterial CABG were 10% greater than for whites (p = 0.05). Blacks had worse inhospital outcomes, including higher odds of stroke (odds ratio 2.41, 95% confidence interval [CI]: 1.80 to 3.25) and prolonged intubation (odds ratio 2.01, 95% CI: 1.77 to 2.28). The increase in postoperative complications did not translate to a difference in inhospital mortality (p = 0.10) between racial cohorts. Moreover, among patients who underwent multiarterial grafting strategies, blacks had a hazard of mortality that was 34% higher (95% CI: 22% to 51%)) than that of their white counterparts. Among black patients, those who underwent multiarterial grafting strategies showed better long-term survival than those undergoing single grafting strategies (hazard ratio 0.86, 95% CI: 0.78 to 0.96). CONCLUSIONS: Despite similar rates of arterial grafting for black patients and white patients in this large single center cohort, black patients continued to have significantly worse late survival when compared with white patients. Continued evaluation as to the causes of this disparity is warranted. PMID- 27717428 TI - The Role of Human Papilloma Virus in Penile Carcinogenesis and Preneoplastic Lesions: A Potential Target for Vaccination and Treatment Strategies. AB - Penile cancer is a rare and devastating disease, especially at advanced stages. The etiology of penile cancer is multifactorial with multiple established risk factors including infection with the human papillomavirus (HPV). Approximately 40% of penile cancers are attributable to HPV, although the literature describing HPV as a prognostic factor is mixed. The pathogenesis of HPV infection as well as vaccination practices may provide valuable therapeutic agents to treat this rare and difficult disease. PMID- 27717427 TI - Should We Perform Carotid Doppler Screening Before Surgical or Transcatheter Aortic Valve Replacement? AB - BACKGROUND: Screening for internal carotid artery stenosis (ICAS) with Doppler ultrasound is commonly used before cardiovascular surgery. Nevertheless, the relationship between ICAS and procedure-related stroke in isolated aortic valve replacement is unclear. METHODS: We retrospectively reviewed patients with artery stenosis who underwent ICAS screening before surgical (SAVR) or transcatheter aortic valve replacement (TAVR) between January 2007 and August 2014. Logistic regression models were used to determine the relation between post-procedure stroke and total (sum of left and right ICAS) and maximal unilateral ICAS. Age, sex, history of atrial fibrillation, cerebrovascular disease and diabetes, left ventricular ejection fraction, and procedure type were considered as covariates. Two-subgroup analyses were performed in patients who underwent TAVR and SAVR, adjusting for procedure specific details. RESULTS: A total of 996 patients underwent ICAS screening before TAVR (n = 467) or SAVR (n = 529). The prevalence of at least >=70% ICAS was 5.2% (n = 52) and incidence of 30-day stroke was 3.4% (n = 34). Eight patients who underwent carotid intervention before valve replacement and 6 patients with poor Doppler images were excluded from the final analysis. We found no statistically significant association between stroke and either the total or maximal unilateral ICAS for all patients (p = 0.13 and p = 0.39, respectively) or those undergoing TAVR (p = 0.27 and p = 0.63, respectively) or SAVR (p = 0.21 and p = 0.36, respectively). CONCLUSIONS: We found no statistically significant association between ICAS severity procedure related stroke after aortic valve replacement. This suggests that universal carotid Doppler screening before isolated TAVR or SAVR is unnecessary. PMID- 27717429 TI - Advances in Penile-Preserving Surgical Approaches in the Management of Penile Tumors. AB - Penile-preserving surgery offers a revolutionary alternative to more traditional radical surgery. It offers better sexual, functional, and psychological results and evidence suggests it achieves this without sacrificing oncological outcomes. We examined the evolving nature of such surgeries, addressing controversies such as safe margins and survival outcomes and discussing more conventional techniques, including laser. At our UK center, we treat a high volume of penile cancer and here, based on such experience, we describe our glans resurfacing, glansectomy, and partial penectomy techniques; their application by disease stage; and the limitations of such surgeries. PMID- 27717430 TI - Contemporary Role of Radiotherapy in the Management of Primary Penile Tumors and Metastatic Disease. AB - Squamous cell cancer of the penis is a radiocurable malignancy all too often managed solely by partial or total penectomy. Effective management of the primary tumor while preserving penile morphology and function is a priority. External radiotherapy and brachytherapy have a role to play in the definitive management of the primary tumor. Surgical nodal staging remains a cornerstone of management because it is the strongest predictor of survival, and inguinal status determines pelvic management. Postoperative radiotherapy of the regional nodes for high-risk pathology is indicated. Chemoradiotherapy should be considered as neoadjuvant treatment for unresectable nodes or as definitive management. PMID- 27717432 TI - Surgical Advances in Inguinal Lymph Node Dissection: Optimizing Treatment Outcomes. AB - Lymphadenectomy (LND) for locally advanced penile cancer is often necessary in patients with suspected disease within the inguinal or pelvic lymph nodes because the results of systemic therapy are somewhat marginal. It has utility in staging, disease prognosis, and treatment in certain men because early dissection of involved lymph nodes improves survival. Despite its mainstay in the management of this disease, inguinal and pelvic lymph node dissection can be associated with significant postoperative complications and patient morbidity. Recent refinements in surgical technique, however, and appropriate patient selection can minimize these risks and lead to better short-term and long-term outcomes. PMID- 27717431 TI - Minimal Invasive Management of Lymph Nodes. AB - Penile cancer is a rare genitourinary malignancy. Lymph node involvement is the single most important factor determining survival in these patients, and those patients with occult disease are difficult to identify on conventional cross sectional imaging. Until recently, lymph node sampling (eg, lymphadenectomy) has been the diagnostic modality of choice in the detection of micrometastasis. More recently, several novel molecular and minimally invasive diagnostic techniques have been developed, which have been demonstrated to decrease the false-negative and -positive results of conventional imaging and lymphadenectomy. This article focuses on the minimally invasive management of lymph nodes in men with penile cancer. PMID- 27717433 TI - Multimodal Therapy in the Management of Advanced Penile Cancer. AB - A multimodal approach to therapy is increasingly used in treating men with advanced penile cancer. Adjuvant chemotherapy improves outcomes in chemotherapy naive men with node-positive positive disease, and neoadjuvant chemotherapy can downstage bulky nodal disease sufficiently to permit surgery and has the potential to offer durable long-term survival. However, there remain several unanswered questions in this field, and international collaboration in the form of clinical trials is required to optimize treatment and improve survival in men with advanced penile cancer. PMID- 27717434 TI - Emerging Systemic Therapies for the Management of Penile Cancer. AB - Penile squamous cell carcinoma (PSCC) is a rare cancer, but is more common in developing countries. Locally advanced and metastatic PSCC is associated with significant morbidity and mortality, with the prognosis remaining extremely poor. The authors searched PubMed and published abstracts for metastatic PSCC studies to describe emerging therapies. Multimodality treatment using chemotherapy, radiation, and consolidative surgery are standard of care.

Distal urethral tumors are usually less advanced at diagnosis compared with proximal tumors and have a good prognosis if treated appropriately. Low-stage distal tumors can be managed successfully with a surgical approach in men or radiation therapy in women. There are no clear-cut indications for the choice of the most appropriate treatment modality. Organ-preserving modalities have shown effective and should be used whenever they do not compromise the oncological safety to decrease the physical and psychological trauma of dismemberment or loss of sexual/urinary function. PMID- 27717436 TI - Management of Proximal Primary Urethral Cancer: Should Multidisciplinary Therapy Be the Gold Standard? AB - Primary urethral cancer (PUC) is a rare, but devastating genitourinary tumor that affects men and women. Although most PUC are localized, proximal PUC frequently presents with locally advanced disease, with 30% to 40% having lymph node metastasis. Single modality surgical or radiation therapy has dismal results. Multimodal therapy with cisplatin-based chemotherapy and consolidation surgery has greatly improved the local recurrence and overall survival rates for this aggressive disease. In locally advanced squamous cell carcinoma of the urethra, radiotherapy combined with radiosensitizing chemotherapy is an option for genital preservation. Prospective, multi-institutional studies are required to further define the optimal multidisciplinary treatment strategy for this destructive disease.

PMID- 27717438 TI - Preneoplastic and Primary Scrotal Cancer: Updates on Pathogenesis and Diagnostic Evaluation. AB - Occupational exposure has been causally linked to scrotal cancer. Primary preventative care and avoiding carcinogenic substances have decreased the incidence and changed the treatment of scrotal cancer. The current incidence of scrotal malignancy is approximately 1 per 1,000,000 male persons/year. The rarity of cases and of research impedes our understanding of the changing nature of scrotal cancer. This article summarizes the current knowledge, focusing mainly on pathogenesis and diagnostic evaluation, which may influence prevention and early recognition of the disease. We stratify scrotal cancer into common histologic subtypes: squamous cell carcinoma, extramammary Paget's disease, and basal cell carcinoma. PMID- 27717439 TI - Surgical Management of Primary Scrotal Cancer. AB - Primary scrotal cancer is a rare urologic malignancy with various histologic subtypes. Management and outcomes are not designed optimally. Surgical excision is the recommended treatment for localized scrotal cancer, with assessment of the margins for disease. Closure of the defect can be performed with primary closure, skin grafts, flaps, or by secondary intention. Analysis of outcomes suggests that high-risk scrotal cancer may have a worse prognosis compared with penile cancer, and low-risk scrotal cancer may have a comparable prognosis. Understanding techniques for management and survival outcomes can help the urologist determine the appropriate course of treatment and improve patient care.

AB - This article reviews the most up-to-date surgical treatment options for the reconstructive management of patients with penile, urethral, and scrotal cancer. Each organ system is examined individually. Techniques and discussion for penile cancer reconstruction include Mohs surgery, glans resurfacing, partial and total glansectomy, and phalloplasty. Included in the penile cancer reconstruction section is the use of penile prosthesis in phalloplasty patients after penectomy, tissue engineering in phallic regeneration, and penile transplantation.

PMID- 27717443 TI - Impact of Gender on the Prognostic Value of Coronary Artery Calcium in Symptomatic Patients With Normal Single-Photon Emission Computed Tomography Myocardial Perfusion. AB - The coronary artery calcium (CAC) score provides independent prognostic value on top of single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI). We sought to determine whether the prognostic value of the CAC score in patients with normal SPECT MPI is gender specific. We studied 3,705 consecutive symptomatic patients without a history of coronary artery disease with normal SPECT MPI. All patients underwent concomitant CAC scoring, which was categorized as CAC score 0, 1 to 99, 100 to 399, 400 to 999, or >=1,000. Major adverse cardiac events were defined as revascularization, nonfatal myocardial infarction, or all-cause mortality. The median CAC score was 9 in women (interquartile range 0 to 113) and 47 in men (interquartile range 1 to 307, p <0.001). The annual event rate was lower in women than in men (1.6% and 2.7%, respectively, p <0.001). When stratified by CAC score, annual event rates were similar (for women and men, respectively: CAC score 0, 0.6% and 0.5%, p = 0.95; CAC score 1 to 99, 0.9% and 1.2%, p = 0.45; CAC score 100 to 399, 2.7% and 3.8%, p = 0.23; CAC score 400 to 999, 3.8% and 5.3%, p = 0.34; CAC score >=1,000, 8.4% and 8.7%, p = 0.99). The CAC score was an independent predictor of major adverse cardiac events in both genders (CAC score >=1,000: hazard ratio for women 8.5, 95% confidence interval 4.0 to 18.1; hazard ratio for men 14.8, 95% confidence interval 5.3 to 41.1). In conclusion, risk for events is similar for both genders when stratified by CAC score, wherein a high CAC score carries a high risk for events despite normal SPECT MPI. Our findings do not reveal a gender-specific prognostic value of the CAC score. PMID- 27717444 TI - Novel insights of ethylene role in strawberry cell wall metabolism. AB - Due to its organoleptic and nutraceutical qualities, strawberry fruit (Fragaria x ananassa, Duch) is a worldwide important commodity. The role of ethylene in the regulation of strawberry cell wall metabolism was studied in fruit from Toyonoka cultivar harvested at white stage, when most changes associated with fruit ripening have begun. Fruit were treated with ethephon, an ethylene-releasing reagent, or with 1-methylcyclopropene (1-MCP), a competitive inhibitor of ethylene action, maintaining a set of non-treated fruit as controls for each condition. Ethephon treated-fruit showed higher contents of hemicelluloses, cellulose and neutral sugars regarding controls, while 1-MCP-treated fruit showed a lower amount of those fractions. On the other hand, ethephon-treated fruit presented a lower quantity of galacturonic acid from ionically and covalently bound pectins regarding controls, while 1-MCP-treated fruit showed higher contents of those components. We also explored the ethylene effect over the mRNA accumulation of genes related to pectins and hemicelluloses metabolism, and a relationship between gene expression patterns and cell wall polysaccharides contents was shown. Moreover, we detected that strawberry necrotrophic pathogens growth more easily on plates containing cell walls from ethephon-treated fruit regarding controls, while a lower growth rate was observed when cell walls from 1 MCP treated fruit were used as the only carbon source, suggesting an effect of ethylene on cell wall structure. Around 60% of strawberry cell wall is made up of pectins, which in turns is 70% made by homogalacturonans. Our findings support the idea of a central role for pectins on strawberry fruit softening and a participation of ethylene in the regulation of this process. PMID- 27717445 TI - miRNA alterations are important mechanism in maize adaptations to low-phosphate environments. AB - Maize is a globally important crop, and a low phosphate (LP) supply frequently limits maize yields in many areas. microRNAs (miRNAs) play important roles in plant development and environmental adaptation. In this study, spatio-temporal miRNA transcript profiling and some of the target genes in the roots and leaves of the maize inbred line Q319 were analyzed in response to LP. Complex small RNA populations were detected after LP culture, and they displayed different patterns in the roots and leaves. Differentially expressed miRNAs can be grouped into 'early' miRNAs, which respond rapidly and are often non-specific to phosphate deficiency, and 'late' miRNAs, which alter the morphology, physiology or metabolism of plants upon prolonged phosphate deficiency. miR827 and miR399 mediated posttranscriptional pathway responses to phosphate availability were conserved and species-specific in maize. Abiotic stress-related miRNAs were engaged in interactions with different signaling and/or metabolic pathways. Auxin related miRNAs and their targets' expression may be involved in root architecture modification and upland growth retardation in maize when subjected to LP. The changes that were found in the expression of miRNAs and their target genes suggested that miRNA regulation/alterations are pivotal mechanisms in maize adaptations to LP environments. A complex regulatory mechanism involving miRNAs in response to the LP environment is present in maize. PMID- 27717446 TI - Arginine-rich motif-tandem CCCH zinc finger proteins in plant stress responses and post-transcriptional regulation of gene expression. AB - Tandem CCCH zinc finger (TZF) proteins are evolutionarily conserved regulators of gene expression at the post-transcriptional level. TZFs target AU-rich RNA elements at 3' un-translated region and recruit catabolic machineries to trigger mRNA degradation. The plant TZF families are over-represented by a class of proteins with a unique TZF domain preceded by an arginine-rich motif (RR-TZF). RR TZF proteins are mainly involved in hormone- and environmental cues-mediated plant growth and stress responses. Numerous reports have suggested that RR-TZF proteins control seed germination, plant size, flowering time, and biotic and abiotic stress responses via regulation of gene expression. Despite growing genetic evidence, the underlying molecular mechanisms are elusive. This review outlines the highly conserved roles of plant RR-TZFs in various stress responses and the potential involvements of RR-TZF proteins in transcriptional and post transcriptional regulation of gene expression. The dynamic subcellular localization of RR-TZF proteins, implication of predominant protein-protein interactions between RR-TZF proteins and stress response mediators and future directions of this research field are also discussed. PMID- 27717447 TI - Arabidopsis clade IV TGA transcription factors, TGA10 and TGA9, are involved in ROS-mediated responses to bacterial PAMP flg22. AB - Reactive oxygen species (ROS) produced in chloroplasts have been proposed to act as signaling molecules for plant immunity through pathogen-associated molecular patterns (PAMPs), such as flg22. To elucidate this process, we herein conducted genetic screening of flg22-sensitive mutants from T-DNA insertion lines lacking chloroplastic H2O2-responsive genes. The results obtained showed that knockout mutants lacking a clade IV TGA transcription factor, TGA10, were more sensitive to the flg22 treatment than wild-type plants. Furthermore, although no flg22 sensitive phenotype was detected in the knockout mutant of another clade IV TGA9, double knockout tga9 tga10 mutants showed more sensitivity to flg22 than single knockout mutants. Transcripts of TGA10 and TGA9 were strongly induced by flg22 in leaves, and this was facilitated by the double knockout of stromal and thylakoid bound ascorbate peroxidases (APX), which are major H2O2 scavengers in chloroplasts. The flg22-induced H2O2 accumulation was maintained at high level in these APXs mutants, indicating the clade IV TGAs may be induced by the ROS. Furthermore, TGA10 was required for the complete activation of the expression of several flg22-responsive genes in plants treated with this PAMP. These have provided a new insight into the relationship between the TGA transcription factors and ROS-mediated signaling in PAMPs responses. PMID- 27717448 TI - Glu-370 in the large subunit influences the substrate binding, allosteric, and heat stability properties of potato ADP-glucose pyrophosphorylase. AB - ADP-glucose pyrophosphorylase (AGPase) is a key allosteric enzyme in plant starch biosynthesis. Plant AGPase is a heterotetrameric enzyme that consists of large (LS) and small subunits (SS), which are encoded by two different genes. In this study, we showed that the conversion of Glu to Gly at position 370 in the LS of AGPase alters the heterotetrameric stability along with the binding properties of substrate and effectors of the enzyme. Kinetic analyses revealed that the affinity of the LSE370GSSWT AGPase for glucose-1-phosphate is 3-fold less than for wild type (WT) AGPase. Additionally, the LSE370GSSWT AGPase requires 3-fold more 3-phosphogyceric acid to be activated. Finally, the LSE370GSSWTAGPase is less heat stable compared with the WT AGPase. Computational analysis of the mutant Gly-370 in the 3D modeled LS AGPase showed that this residue changes charge distribution of the surface and thus affect stability of the LS AGPase and overall heat stability of the heterotetrameric AGPase. In summary, our results show that LSE370 intricately modulate the heat stability and enzymatic activity of potato the AGPase. PMID- 27717449 TI - GL2-type homeobox gene Roc4 in rice promotes flowering time preferentially under long days by repressing Ghd7. AB - Under long day (LD) lengths, flowering can be delayed in rice by modulating several regulatory genes. We found activation tagging lines that showed an early flowering phenotype preferentially under LD conditions. Expression of Rice outermost cell-specific gene 4 (Roc4), encoding a homeodomain Leu-zipper class IV family protein, was significantly increased. Transcript levels of Grain number, plant height, and heading date7 (Ghd7) were significantly reduced while those of Ghd7 downstream genes were increased. However, other flowering regulators were unaffected. Whereas constitutive overexpression of Roc4 in 'Dongjin' japonica rice, which carries active Ghd7, also caused LD-preferential early flowering, its overexpression in 'Longjing27' rice, which is defective in functional Ghd7, did not produce the same result. This confirmed that Roc4 regulates flowering time mainly through Ghd7. Phytochromes and O. sativa GIGANTEA (OsGI) function upstream of Roc4. Transgenic plants showed ubiquitous expression of the beta-glucuronidase reporter gene under the Roc4 promoter. Furthermore, Roc4 had transcriptional activation activity in the N-terminal region of the StAR-related lipid-transfer domain. All of these findings are evidence that Roc4 is an LD-preferential flowering enhancer that functions downstream of phytochromes and OsGI, but upstream of Ghd7. PMID- 27717451 TI - ABA accumulation in water-stressed Citrus roots does not rely on carotenoid content in this organ. AB - Sustained abscisic acid (ABA) accumulation in dehydrated citrus roots depends on the transport from aerial organs. Under this condition, the role of the beta,beta carotenoids (ABA precursors) to the de novo synthesis of ABA in roots needs to be clarified since their low availability in this organ restricts its accumulation. To accomplish that, detached citrus roots were exposed to light (to increase their carotenoid content) and subsequently dehydrated (to trigger ABA accumulation). Stress imposition sharply decreased the pool of beta,beta carotenoids but, unexpectedly, no concomitant rise in ABA content was observed. Contrastingly, roots of intact plants (with low levels of carotenoids) showed a similar decrease of ABA precursor together with a significant ABA accumulation. Furthermore, upon dehydration both types of roots showed similar upregulation of the key genes involved in biosynthesis of carotenoids and ABA (CsPSY3a; CsbetaCHX1; CsbetaCHX2; CsNCED1; CsNCED2), demonstrating a conserved transcriptional response triggered by water stress. Thus, the sharp decrease in root carotenoid levels in response to dehydration should be related to other stress-related signals instead of contributing to ABA biosynthesis. In summary, ABA accumulation in dehydrated-citrus roots largely relies on the presence of the aerial organs and it is independent of the amount of available root beta,beta carotenoids. PMID- 27717450 TI - Sucrose-induced anthocyanin accumulation in vegetative tissue of Petunia plants requires anthocyanin regulatory transcription factors. AB - The effects of three different sucrose concentrations on plant growth and anthocyanin accumulation were examined in non-transgenic (NT) and transgenic (T2) specimens of the Petunia hybrida cultivar 'Mirage rose' that carried the anthocyanin regulatory transcription factors B-Peru+mPAP1 or RsMYB1. Anthocyanin accumulation was not observed in NT plants in any treatments, whereas a range of anthocyanin accumulation was observed in transgenic plants. The anthocyanin content detected in transgenic plants expressing the anthocyanin regulatory transcription factors (B-Peru+mPAP1 or RsMYB1) was higher than that in NT plants. In addition, increasing sucrose concentration strongly enhanced anthocyanin content as shown by quantitative real-time polymerase chain reaction (qRT-PCR) analysis, wherein increased concentrations of sucrose enhanced transcript levels of the transcription factors that are responsible for the induction of biosynthetic genes involved in anthocyanin synthesis; this pattern was not observed in NT plants. In addition, sucrose affected plant growth, although the effects were different between NT and transgenic plants. Taken together, the application of sucrose could enhance anthocyanin production in vegetative tissue of transgenic Petunia carrying anthocyanin regulatory transcription factors, and this study provides insights about interactive effects of sucrose and transcription factors in anthocyanin biosynthesis in the transgenic plant. PMID- 27717452 TI - Molecular and genetic characterization of a self-compatible apple cultivar, 'CAU 1'. AB - In this study, we characterized a naturally occurring self-compatible apple cultivar, 'CAU-1' (S1S9), and studied the underlying mechanism that causes its compatibility. Analyses of both fruit set rate and seed number after self pollination or cross-pollination with 'Fuji' (S1S9), and of pollen tube growth, demonstrated that 'CAU-1' is self-compatible. Genetic analysis by S-RNase PCR typing of selfed progeny of 'CAU-1' revealed the presence of all progeny classes (S1S1, S1S9, and S9S9). Moreover, no evidence of S-allele duplication was found. These findings support the hypothesis that loss of function of an S-locus unlinked pollen-part mutation (PPM) expressed in pollen, rather than a natural mutation in the pollen-S gene (S1- and S9- haplotype), leads to SI breakdown in 'CAU-1'. In addition, there were no significant differences in pollen morphology or fertility between 'Fuji' and 'CAU-1'. However, we found that the effect of S1- and S9-RNase on the SI behavior of pollen could not be addressed better in 'CAU 1' than in 'Fuji'. Furthermore, we found that a pollen-expressed hexose transporter, MdHT1, interacted with S-RNases and showed significantly less expression in 'CAU-1' than in 'Fuji' pollen tubes. These findings support the hypothesis that MdHT1 may participate in S-RNase internalization during the SI process, and decrease of MdHT1 expression in 'CAU-1' hindered the release of self S-RNase into the cytoplasm of pollen tubes, thereby protecting pollen from the cytotoxicity of S-RNase, finally probably resulting in self-compatibility. Together, these findings indicate that S-locus external factors are required for gametophytic SI in the Rosaceae subtribe Pyrinae. PMID- 27717453 TI - Synergies and antagonisms in virus interactions. AB - Metagenomic surveys and data from next generation sequencing revealed that mixed infections among plant viruses are probably a rule rather than an exception in natural pathosystems. The documented cases may range from synergism to antagonism, which may depend from the spatiotemporal order of arrival of the viruses on the host and upon the host itself. In synergistic interactions, the measurable differences in replication, phenotypic and cytopathological changes, cellular tropism, within host movement, and transmission rate of one of the two viruses or both are increased. Conversely, a decrease in replication, or inhibition of one or more of the above functions by one virus against the other, leads to an antagonistic interaction. Viruses may interact directly and by transcomplementation of defective functions or indirectly, through responses mediated by the host like the defense mechanism based on RNA silencing. Outcomes of these interactions can be applied to the risk assessment of transgenic crops expressing viral proteins, or cross-protected crops for the identification of potential hazards. Prior to experimental evidence, mathematical models may help in forecasting challenges deriving from the great variety of pathways of synergistic and antagonistic interactions. Actually, it seems that such predictions do not receive sufficient credit in the framework of agriculture. PMID- 27717454 TI - Short versus long term effects of cyanide on sugar metabolism and transport in dormant walnut kernels. AB - Tree seed dormancy release by cold stratification accompanies with the embryo increased gluconeogenesis competence. Cyanide also breaks seed dormancy however, integrated information about its effects on carbon metabolism is lacking. Accordingly, the impacts of HCN on germination, lipid gluconeogenesis and sugar transport capacity of walnut (Juglans regia L.) kernels were investigated during 10-days period prior to radicle protrusion. HCN increased walnut kernel germination and within four days of kernel incubation, hastened the decline of starch, reducing and non-reducing sugars and led to greater activities of alkaline invertase and glucose-6-phosphate dehydrogenase. From four days of kernel incubation onwards, starch and non-reducing sugars accumulated only in the HCN treated axes. Cyanide also increased the activities of phosphoenolpyruvate carboxykinase and glyoxysomal succinate oxidase and led to greater acid invertase activity during the aforementioned period. The expressions of both sucrose transporter (JrSUT1) and H+-ATPase (JrAHA1) genes especially in cotyledons and H+ ATPase activity in kernels were significantly enhanced by exposure to cyanide. Thus in short-term HCN led to prevalence of carbohydrate catabolic events such as oxidative pentose phosphate pathway and possibly glycolysis in dormant walnut kernels. Long-term effects however, are increased gluconeogenesis and enhanced sugar transport capacity of kernels as a prerequisite for germination. PMID- 27717455 TI - Impact of anatomical traits of maize (Zea mays L.) leaf as affected by nitrogen supply and leaf age on bundle sheath conductance. AB - The mechanism of photosynthesis in C4 crops depends on the archetypal Kranz anatomy. To examine how the leaf anatomy, as altered by nitrogen supply and leaf age, affects the bundle sheath conductance (gbs), maize (Zea mays L.) plants were grown under three contrasting nitrogen levels. Combined gas exchange and chlorophyll fluorescence measurements were done on fully grown leaves at two leaf ages. The measured data were analysed using a biochemical model of C4 photosynthesis to estimate gbs. The leaf microstructure and ultrastructure were quantified using images obtained from micro-computed tomography and microscopy. There was a strong positive correlation between gbs and leaf nitrogen content (LNC) while old leaves had lower gbs than young leaves. Leaf thickness, bundle sheath cell wall thickness and surface area of bundle sheath cells per unit leaf area (Sb) correlated well with gbs although they were not significantly affected by LNC. As a result, the increase of gbs with LNC was little explained by the alteration of leaf anatomy. In contrast, the combined effect of LNC and leaf age on Sb was responsible for differences in gbs between young leaves and old leaves. Future investigations should consider changes at the level of plasmodesmata and membranes along the CO2 leakage pathway to unravel LNC and age effects further. PMID- 27717456 TI - REPRESSOR OF ULTRAVIOLET-B PHOTOMORPHOGENESIS function allows efficient phototropin mediated ultraviolet-B phototropism in etiolated seedlings. AB - Ultraviolet B (UV-B) light is a part of the solar radiation which has significant effects on plant morphology, even at low doses. In Arabidopsis, many of these morphological changes have been attributed to a specific UV-B receptor, UV resistance locus 8 (UVR8). Recent findings showed that next to phototropin regulated phototropism, UVR8 mediated signaling is able of inducing directional bending towards UV-B light in etiolated seedlings of Arabidopsis, in a phototropin independent manner. In this study, kinetic analysis of phototropic bending was used to evaluate the relative contribution of each of these pathways in UV-B mediated phototropism. Diminishing UV-B light intensity favors the importance of phototropins. Molecular and genetic analyses suggest that UV-B is capable of inducing phototropin signaling relying on phototropin kinase activity and regulation of NPH3. Moreover, enhanced UVR8 responses in the UV-B hypersensitive rup1rup2 mutants interferes with the fast phototropin mediated phototropism. Together the data suggest that phototropins are the most important receptors for UV-B induced phototropism in etiolated seedlings, and a RUP mediated negative feedback pathway prevents UVR8 signaling to interfere with the phototropin dependent response. PMID- 27717457 TI - The Agrobacterium rhizogenes oncogenes rolB and ORF13 increase formation of generative shoots and induce dwarfism in Arabidopsis thaliana (L.) Heynh. AB - Plant transformation with the wild type Ri plasmid T-DNA of Agrobacterium rhizogenes is a promising method for breeding of compact plants and has been the subject of numerous studies. However, knowledge concerning the isolated functions of single genes and ORFs from the plasmid is limited. The rolB and ORF13 oncogenes of A. rhizogenes show considerable promise in plant breeding, but have not been comprehensively studied. Detailed information regarding the morphological impact of specific genes of the Ri plasmid will allow for optimized targeted breeding of plants transformed with the wild type Ri plasmid T-DNA. rolB and ORF13 were recombined into the genome of Arabidopsis thaliana using Gateway(r) cloning and the effect on plant growth was assessed biometrically throughout the plants' life cycle. rolB-lines exhibited dwarfing, early necrosis of rosette leaves, altered leaf and flower morphology, and developed an increased number of inflorescences per rosette area compared to the wild type. ORF13-lines were extremely dwarfed, attaining only ca. 1% of the rosette area of the wild type, leaf and flower size was reduced, and the shape modified. The study documents that the traits inferred by the rolB oncogene yield plants with increased formation of generative shoots, but also result in some degree of premature senescence of vegetative organs. The extreme dwarfism seen in ORF13 lines indicate that this oncogene may be more important in the dwarfing response of plants transformed with the wild type Ri plasmid T-DNA than previously assumed and that transformation with this oncogene induces a very compact phenotype. PMID- 27717458 TI - Genome wide association mapping of stripe rust resistance in Afghan wheat landraces. AB - Mining of new genetic resources is of paramount importance to combat the alarming spread of stripe rust disease and breakdown of major resistance genes in wheat. We conducted a genome wide association study on 352 un-utilized Afghan wheat landraces against stripe rust resistance in eight locations. High level of disease variation was observed among locations and a core-set of germplasm showed consistence performance. Linkage disequilibrium (LD) decayed rapidly (R2~0.16 at 0cM) due to germplasm peerless diversity. The mixed linear model resulted in ten marker-trait associations (MTAs) across all environments representing five QTL. The extensively short LD blocks required us to repeat the analysis with less diverse subset of 220 landraces in which R2 decayed below 0.2 at 0.3cM. The subset GWAS resulted in 36 MTAs clustered in nine QTL. The subset analysis validated three QTL previously detected in the full list analysis. Overall, the study revealed that stripe rust epidemics in the geographical origin of this germplasm through time have permitted for selecting novel resistance loci. PMID- 27717459 TI - The down-regulation of the genes encoding Isoamylase 1 alters the starch composition of the durum wheat grain. AB - In rice, maize and barley, the lack of Isoamylase 1 activity materially affects the composition of endosperm starch. Here, the effect of this deficiency in durum wheat has been characterized, using transgenic lines in which Isa1 was knocked down via RNAi. Transcriptional profiling confirmed the partial down-regulation of Isa1 and revealed a pleiotropic effect on the level of transcription of genes encoding other isoamylases, pullulanase and sucrose synthase. The polysaccharide content of the transgenic endosperms was different from that of the wild type in a number of ways, including a reduction in the content of starch and a moderate enhancement of both phytoglycogen and beta-glucan. Some alterations were also induced in the distribution of amylopectin chain length and amylopectin fine structure. The amylopectin present in the transgenic endosperms was more readily hydrolyzable after a treatment with hydrochloric acid, which disrupted its semi crystalline structure. The conclusion was that in durum wheat, Isoamylase 1 is important for both the synthesis of amylopectin and for determining its internal structure. PMID- 27717460 TI - Cambial stem cells and their niche. AB - Unlike animals, plants often have an indefinite genetic potency to form new organs throughout their entire lifespan. Growth and organogenesis are driven by cell divisions in meristems at distinct sites within the plant. Since the meristems contributing to axial thickening in dicots (cambia) are separated from places where axes elongate (apical meristems); there is a need of communication to coordinate growth. In their behavior, some meristematic cells resemble animal stem cells whose daughter cells either maintain the capacity to divide over a long period of time or undergo differentiation. The behavior of stem cells is regulated by their microenvironment, the so called niche. The stem- and niche cell concept is now also widely accepted for apical meristems. An integral part of the cambial niche has recently been localized to the phloem. It steers cell division activity in the cambium via the release of a peptide signal and may be a hub to integrate signals from other stem cell populations to coordinate growth. Although these signals have yet to be determined, the discovery of the cambial niche cells will pave the way for a better understanding of inter-meristematic communication and cambial stem cell behavior. PMID- 27717461 TI - Genome-wide analysis of the Hsp70 family genes in pepper (Capsicum annuum L.) and functional identification of CaHsp70-2 involvement in heat stress. AB - Hsp70s function as molecular chaperones and are encoded by a multi-gene family whose members play a crucial role in plant response to stress conditions, and in plant growth and development. Pepper (Capsicum annuum L.) is an important vegetable crop whose genome has been sequenced. Nonetheless, no overall analysis of the Hsp70 gene family is reported in this crop plant to date. To assess the functionality of Capsicum annuum Hsp70 (CaHsp70) genes, pepper genome database was analyzed in this research. A total of 21 CaHsp70 genes were identified and their characteristics were also described. The promoter and transcript expression analysis revealed that CaHsp70s were involved in pepper growth and development, and heat stress response. Ectopic expression of a cytosolic gene, CaHsp70-2, regulated expression of stress-related genes and conferred increased thermotolerance in transgenic Arabidopsis. Taken together, our results provide the basis for further studied to dissect CaHsp70s' function in response to heat stress as well as other environmental stresses. PMID- 27717462 TI - Plastidic P2 glucose-6P dehydrogenase from poplar is modulated by thioredoxin m type: Distinct roles of cysteine residues in redox regulation and NADPH inhibition. AB - A cDNA coding for a plastidic P2-type G6PDH isoform from poplar (Populus tremula x tremuloides) has been used to express and purify to homogeneity the mature recombinant protein with a N-terminus His-tag. The study of the kinetic properties of the recombinant enzyme showed an in vitro redox sensing modulation exerted by reduced DTT. The interaction with thioredoxins (TRXs) was then investigated. Five cysteine to serine variants (C145S - C175S - C183S - C195S - C242S) and a variant with a double substitution for Cys175 and Cys183 (C175S/C183S) have been generated, purified and biochemically characterized in order to investigate the specific role(s) of cysteines in terms of redox regulation and NADPH-dependent inhibition. Three cysteine residues (C145, C194, C242) are suggested to have a role in controlling the NADP+ access to the active site, and in stabilizing the NADPH regulatory binding site. Our results also indicate that the regulatory disulfide involves residues Cys175 and Cys183 in a position similar to those of chloroplastic P1-G6PDHs, but the modulation is exerted primarily by TRX m-type, in contrast to P1-G6PDH, which is regulated by TRX f. This unexpected specificity indicates differences in the mechanism of regulation, and redox sensing of plastidic P2-G6PDH compared to chloroplastic P1 G6PDH in higher plants. PMID- 27717463 TI - A Raf-like MAPKKK gene, GhRaf19, negatively regulates tolerance to drought and salt and positively regulates resistance to cold stress by modulating reactive oxygen species in cotton. AB - Mitogen-activated protein kinase kinase kinases (MAPKKKs) function at the top level of MAPK cascades and play important roles in plant development and stress responses. Although MAPKKKs comprise the largest family in the MAPK cascades, very few Raf-like MAPKKKs have been functionally identified, especially in the economically important crop cotton. In this study, a Raf-like MAPKKK gene, GhRaf19, was characterized for the first time in cotton. Our data show that the expression of GhRaf19 was inhibited by PEG and NaCl and induced by cold (4 degrees C) and H2O2. Furthermore, when GhRaf19 was silenced in cotton using virus induced gene silencing (VIGS), tolerance to drought and salt stress were enhanced, the accumulation of reactive oxygen species (ROS) was reduced, and ROS related gene expression was increased. Consistent with these results, in N. benthamiana, overexpressing-GhRaf19 reduced tolerance to drought and salt. However, GhRaf19-silenced plants showed lowered resistance to cold in cotton, and this effect was correlated with the accumulation of ROS. In contrast, overexpressing GhRaf19 in N. benthamiana increased resistance to cold by inducing higher levels of expression and activity of ROS-related antioxidant genes/enzymes. These results indicate that GhRaf19 negatively regulates tolerance to drought and salt and positively regulates resistance to cold stress by modulating cellular ROS in cotton. PMID- 27717464 TI - Nitric oxide is involved in stomatal development by modulating the expression of stomatal regulator genes in Arabidopsis. AB - As sessile organisms, plants require many flexible strategies to adapt to the environment. Although some environmental signaling pathways regulating stomatal development have been identified, how stomatal regulators are modulated by internal and external signals to determine the final stomatal abundance requires further exploration. In our studies, we found that nitric oxide (NO) promotes stomatal development with increased stomatal index as well as the relative number of meristemoids and guard mother cells [%(M+GMC)] in NO-treated wild-type Arabidopsis plants; this role of NO was further verified in the nox1 mutant, which exhibits higher NO levels, and the noa1 mutant, which exhibits low NO accumulation. To gain insight into the molecular mechanisms underlying the effect of NO, we further assayed the expression of genes involved in stomatal development and found that NO induces the expression of the master regulators SPCH, MUTE and SCRM2 to initiate stomatal development. In addition, MPK6 is also involved in NO-promoted stomatal development, as MPK6 expression was repressed in nox1 and NO-treated plants, and transgenic plants overexpressing MPK6 were less sensitive to SNP treatment in terms of changes in the%(M+GMC). Thus, our study shows that NO promotes the production of stomata by up-regulating the expression of SPCH, MUTE and SCRM2 and down-regulating MPK6 expression.

AB - Peroxiredoxins are ubiquitous thiol-dependent peroxidases for which chaperone and signaling roles have been reported in various types of organisms in recent years. In plants, the peroxidase function of the two typical plastidial 2-Cys peroxiredoxins (2-Cys PRX A and B) has been highlighted while the other functions, particularly in ROS-dependent signaling pathways, are still elusive notably due to the lack of knowledge of interacting partners. Using an ex vivo approach based on co-immunoprecipitation of leaf extracts from Arabidopsis thaliana wild-type and mutant plants lacking 2-Cys PRX expression followed by mass spectrometry-based proteomics, 158 proteins were found associated with 2-Cys PRXs. Already known partners like thioredoxin-related electron donors (Chloroplastic Drought-induced Stress Protein of 32kDa, Atypical Cysteine Histidine-rich Thioredoxin 2) and enzymes involved in chlorophyll synthesis (Protochlorophyllide OxidoReductase B) or carbon metabolism (Fructose-1,6 BisPhosphatase) were identified, validating the relevance of the approach. Bioinformatic and bibliographic analyses allowed the functional classification of the identified proteins and revealed that more than 40% are localized in plastids. The possible roles of plant 2-Cys PRXs in redox signaling pathways are discussed in relation with the functions of the potential partners notably those involved in redox homeostasis, carbon and amino acid metabolisms as well as chlorophyll biosynthesis. PMID- 27717465 TI - Temporal and spatial expression and function of TaDlea3 in Triticum aestivum during developmental stages under drought stress. AB - Drought stress is a major factor limiting wheat growth and productivity. Late embryogenesis abundant (LEA) proteins are tolerant to water-related stress. To reveal the regulatory mechanisms of LEA proteins under drought stress, we cloned a novel group 3 LEA gene, namely, TaDlea3, from wheat (Triticum aestivum L.) Shaanhe 6. Subcellular localization assay showed that TaDlea3 protein accumulated in the cytoplasm. Quantitative real-time polymerase chain reaction results revealed that TaDlea3 expression was induced by drought stress. Western blot results indicated that TaDlea3 protein expression gradually increased with drought stress during four different developmental stages. Under normal conditions, no obvious phenotype difference was observed between the transgenic and wild-type seedlings. Meanwhile, the overexpression of TaDlea3 in Arabidopsis resulted in enhanced tolerance to drought stress, as determined by the assessment of antioxidant enzyme activities. Our results provide a basis for highly detailed functional analyses of LEA proteins and offer a promising approach for improving the tolerances of wheat cultivars to drought stress through genetic engineering. PMID- 27717467 TI - Induced plant-defenses suppress herbivore reproduction but also constrain predation of their offspring. AB - Inducible anti-herbivore defenses in plants are predominantly regulated by jasmonic acid (JA). On tomato plants, most genotypes of the herbivorous generalist spider mite Tetranychus urticae induce JA defenses and perform poorly on it, whereas the Solanaceae specialist Tetranychus evansi, who suppresses JA defenses, performs well on it. We asked to which extent these spider mites and the predatory mite Phytoseiulus longipes preying on these spider mites eggs are affected by induced JA-defenses. By artificially inducing the JA-response of the tomato JA-biosynthesis mutant def-1 using exogenous JA and isoleucine (Ile), we first established the relationship between endogenous JA-Ile-levels and the reproductive performance of spider mites. For both mite species we observed that they produced more eggs when levels of JA-Ile were low. Subsequently, we allowed predatory mites to prey on spider mite-eggs derived from wild-type tomato plants, def-1 and JA-Ile-treated def-1 and observed that they preferred, and consumed more, eggs produced on tomato plants with weak JA defenses. However, predatory mite oviposition was similar across treatments. Our results show that induced JA responses negatively affect spider mite performance, but positively affect the survival of their offspring by constraining egg-predation. PMID- 27717469 TI - De novo transcriptome assembly and identification of the gene conferring a "pandan-like" aroma in coconut (Cocos nucifera L.). AB - Thailand's aromatic coconut (Cocos nucifera L.) is a special type of green dwarf coconut, the liquid endosperm of which is characterized by a pleasant "pandan like" aroma due to the presence of 2-acetyl-1-pyrroline (2AP). The aim of this study was to perform a de novo assembly of transriptome from C. nucifera endosperm and to identify the gene responsible for 2AP biosynthesis. CnAMADH2 was identified as an ortholog of the rice aromatic gene and a G-to-C substitution found in exon 14 was associated with 2AP content in the aromatic green dwarf coconut accessions. The base substitution caused an amino-acid change, alanine-to proline, at position 442 (P442A). The presence of P at this position might alter the steric conformation at the loop region and subsequently result in an unstabilized dimer conformation that could lower AMADH enzyme activity. Among AMADH/BADH protein sequences in different plant species, the P442A mutation was found exclusively in aromatic coconut. The PCR marker developed based on this sequence variation can perfectly detect the aromatic and non-aromatic alleles of the gene. This study confirms the hypothesis that plants may share a mechanism of 2AP biosynthesis. This is the first identification of the gene associated with 2AP biosynthesis in a tree plant. PMID- 27717468 TI - Expression of a grape (Vitis vinifera) bZIP transcription factor, VlbZIP36, in Arabidopsis thaliana confers tolerance of drought stress during seed germination and seedling establishment. AB - Drought is one of the most serious factors that limit agricultural productivity and there is considerable interest in understanding the molecular bases of drought responses and their regulation. While numbers of basic leucine zipper (bZIP) transcription factors (TFs) are known to play key roles in response of plants to various abiotic stresses, only a few group K bZIP TFs have been functionally characterized in the context of stress signaling. In this study, we characterized the expression of the grape (Vitis vinifera) group K bZIP gene, VlbZIP36, and found evidence for its involvement in response to drought and the stress-associated phytohormone abscisic acid (ABA). Transgenic Arabidopsis thaliana lines over-expressing VlbZIP36 under the control of a constitutive promoter showed enhanced dehydration tolerance during the seed germination stage, as well as in the seedling and mature plant stages. The results indicated that VlbZIP36 plays a role in drought tolerance by improving the water status, through limiting water loss, and mitigating cellular damage. The latter was evidenced by reduced cell death, lower electrolyte leakage in the transgenic plants, as well as by increased activities of antioxidant enzymes. We concluded that VlbZIP36 enhances drought tolerance through the transcriptional regulation of ABA-/stress related genes. PMID- 27717470 TI - Seed maturation: Simplification of control networks in plants. AB - Networks controlling developmental or metabolic processes in plants are often complex as a consequence of the duplication and specialisation of the regulatory genes as well as the numerous levels of transcriptional and post-transcriptional controls added during evolution. Networks serve to accommodate multicellular complexity and increase robustness to environmental changes. Mathematical simplification by regrouping genes or pathways in a limited number of hubs has facilitated the construction of models for complex traits. In a complementary approach, a biological simplification can be achieved by using genetic modification to understand the core and singular ancestral function of the network, which is likely to be more prevalent within the plant kingdom rather than specific to a species. With this viewpoint, we review examples of simplification successfully undertaken in yeast and other organisms. A strategy of progressive complementation of single, double and triple mutants of seed maturation confirmed the fundamental role of the AFL sub-family of B3 transcription factors as master regulators of seed maturation, illustrating that biological simplification of complex networks could be more widely applied in plants. Defining minimal control networks will facilitate evolutionary comparisons of regulatory processes and the identification of an essential gene set for synthetic biology. PMID- 27717471 TI - Genetic variability of the phloem sap metabolite content of maize (Zea mays L.) during the kernel-filling period. AB - Using a metabolomic approach, we have quantified the metabolite composition of the phloem sap exudate of seventeen European and American lines of maize that had been previously classified into five main groups on the basis of molecular marker polymorphisms. In addition to sucrose, glutamate and aspartate, which are abundant in the phloem sap of many plant species, large quantities of aconitate and alanine were also found in the phloem sap exudates of maize. Genetic variability of the phloem sap composition was observed in the different maize lines, although there was no obvious relationship between the phloem sap composition and the five previously classified groups. However, following hierarchical clustering analysis there was a clear relationship between two of the subclusters of lines defined on the basis of the composition of the phloem sap exudate and the earliness of silking date. A comparison between the metabolite contents of the ear leaves and the phloem sap exudates of each genotype, revealed that the relative content of most of the carbon- and nitrogen containing metabolites was similar. Correlation studies performed between the metabolite content of the phloem sap exudates and yield-related traits also revealed that for some carbohydrates such as arabitol and sucrose there was a negative or positive correlation with kernel yield and kernel weight respectively. A posititive correlation was also found between kernel number and soluble histidine. PMID- 27717472 TI - The coordinated regulation of Na+ and K+ in Hordeum brevisubulatum responding to time of salt stress. AB - Hordeum brevisubulatum, called as wild barley, is a useful monocotyledonous halophyte for soil improvement in northern China. Although previously studied, its main salt tolerance mechanism remained controversial. The current work showed that shoot Na+ concentration was increased rapidly with stress time and significantly higher than in wheat during 0-168h of 100mM NaCl treatment. Similar results were also found under 25 and 50mM NaCl treatments. Even K+ was increased from 0.01 to 50mM in the cultural solution, no significant effect was found on tissue Na+ concentrations. Interestingly, shoot growth was improved, and stronger root activity was maintained in H. brevisubulatum compared with wheat after 7days treatment of 100mM NaCl. To investigate the long-term stress impact on tissue Na+, 100mM NaCl was prolonged to 60 days. The maximum values of Na+ concentrations were observed at 7th in shoot and 14th day in roots, respectively, and then decreased gradually. Micro-electrode ion flux estimation was used and it was found that increasing Na+ efflux while maintaining K+ influx were the major strategies to reduce the Na+ concentration during long-term salt stress. Moreover, leaf Na+ secretions showed little contribution to the tissue Na+ decrease. Thereby, the physiological mechanism for H. brevisubulatum to survive from long-term salt stress was proposed that rapid Na+ accumulation occurred in the shoot to respond the initial salt shock, then Na+ efflux was triggered and K+ influx was activated to maintain a stable K+/Na+ ratio in tissues. PMID- 27717473 TI - Spatial differences in (Z)-3-hexen-1-ol production preferentially reduces Spodoptera litura larva attack on the young leaves of Nicotiana benthamiana. AB - Plants synthesize specialized metabolites which possess extremely important ecological functions including direct defense, indirect defense, and signaling. The optimal defense theory (ODT) proposes that defensive metabolites are preferentially allocated to the tissues with high fitness value or in locations that are easily injured. In our present study, using the model plant Nicotiana benthamiana, we found that direct defense of N. benthamiana against Spodoptera litura (Fabricius) larvae showed spatial differences in the sites producing defensive chemicals. The upper leaves possessed significantly stronger direct defense ability than the middle and lower leaves. Interestingly, the strong defense ability of the upper leaves was not due to occurrences of well-known defensive metabolites such as nicotine and chlorogenic acid. After damage, the middle and lower leaves emitted higher amounts of (Z)-3-hexen-1-ol than the upper leaves, which could both attract larvae and significantly increase the amount of middle and lower leaf eaten by the larvae. The spatial difference in (Z)-3-hexen 1-ol emission may be due to spatial differences in expression of lipoxygenase (NbLOX2), which is responsible for the formation and emission of (Z)-3-hexen-1 ol. This study provided new insight into ODT, showing that plants effectively protect easily injured tissues through reduction in concentration of herbivore feeding stimulant in the tissues. PMID- 27717474 TI - Genome-wide development and deployment of informative intron-spanning and intron length polymorphism markers for genomics-assisted breeding applications in chickpea. AB - The discovery and large-scale genotyping of informative gene-based markers is essential for rapid delineation of genes/QTLs governing stress tolerance and yield component traits in order to drive genetic enhancement in chickpea. A genome-wide 119169 and 110491 ISM (intron-spanning markers) from 23129 desi and 20386 kabuli protein-coding genes and 7454 in silico InDel (insertion-deletion) (1-45-bp)-based ILP (intron-length polymorphism) markers from 3283 genes were developed that were structurally and functionally annotated on eight chromosomes and unanchored scaffolds of chickpea. A much higher amplification efficiency (83%) and intra-specific polymorphic potential (86%) detected by these markers than that of other sequence-based genetic markers among desi and kabuli chickpea accessions was apparent even by a cost-effective agarose gel-based assay. The genome-wide physically mapped 1718 ILP markers assayed a wider level of functional genetic diversity (19-81%) and well-defined phylogenetics among domesticated chickpea accessions. The gene-derived 1424 ILP markers were anchored on a high-density (inter-marker distance: 0.65cM) desi intra-specific genetic linkage map/functional transcript map (ICC 4958*ICC 2263) of chickpea. This reference genetic map identified six major genomic regions harbouring six robust QTLs mapped on five chromosomes, which explained 11-23% seed weight trait variation (7.6-10.5 LOD) in chickpea. The integration of high-resolution QTL mapping with differential expression profiling detected six including one potential serine carboxypeptidase gene with ILP markers (linked tightly to the major seed weight QTLs) exhibiting seed-specific expression as well as pronounced up-regulation especially in seeds of high (ICC 4958) as compared to low (ICC 2263) seed weight mapping parental accessions. The marker information generated in the present study was made publicly accessible through a user-friendly web resource, "Chickpea ISM-ILP Marker Database". The designing of multiple ISM and ILP markers (2-5 markers/gene) from an individual gene (transcription factor) with numerous aforementioned desirable genetic attributes can widen the user preference to select suitable primer combination for simultaneous large-scale assaying of functional allelic variation, natural allelic diversity, molecular mapping and expression profiling of genes among chickpea accessions. This will essentially accelerate the identification of functionally relevant molecular tags regulating vital agronomic traits for genomics-assisted crop improvement by optimal resource expenses in chickpea. PMID- 27717475 TI - Identification of stable QTLs for seed oil content by combined linkage and association mapping in Brassica napus. AB - Seed oil content is an important agricultural trait in rapeseed breeding. Although numerous quantitative trait locus (QTL) have been identified, most of them cannot be applied in practical breeding mainly due to environmental instability or large confidence intervals. The purpose of this study was to identify and validate high quality and more stable QTLs by combining linkage mapping and genome-wide association study (GWAS). For linkage mapping, we constructed two F2 populations from crosses of high-oil content (~50%) lines 6F313 and 61616 with a low-oil content (~40%) line 51070. Two high density linkage maps spanned 1987cM (1659 bins) and 1856cM (1746 bins), respectively. For GWAS, we developed more than 34,000 high-quality SNP markers based on 227 accessions. Finally, 40 QTLs and 29 associations were established by linkage and association mapping in different environments. After merging the results, 32 consensus QTLs were obtained and 7 of them were identified by both mapping methods. Seven overlapping QTLs covered an average confidence interval of 183kb and explained the phenotypic variation of 10.23 to 24.45%. We further developed allele-specific PCR primers to identify each of the seven QTLs. These stable QTLs should be useful in gene cloning and practical breeding application. PMID- 27717476 TI - The Cholodny-Went theory does not explain hydrotropism. AB - Optimization of water foraging by plants is partially achieved by the ability of roots to direct growth towards high water potential, a phenomenon termed hydrotropism. In contrast to gravitropism and phototropism, which require auxin redistribution, as suggested by the Cholodny-Went theory, hydrotropism is not mediated by the phytohormone auxin, which raises questions about the mechanism underlying this tropic response. Here we specify the open questions in this field of research and discuss the possible interactions of abscisic acid, calcium and reactive oxygen species as part of a dynamic system of sensing water potential in the root tip, transmission of the signal to the root elongation zone and promoting root curvature towards water. We conclude that root hydrotropism is mediated by inter-cellular signals that are not explained by the Cholodny-Went theory. PMID- 27717477 TI - Sunflower HaGPAT9-1 is the predominant GPAT during seed development. AB - In oil crops, triacylglycerol biosynthesis is an important metabolic pathway in which glycerol-3-phosphate acyltransferase (GPAT) performs the first acylation step. Mass spectrometry analysis of developing sunflower (Helianthus annuus) seed membrane fractions identified an abundant GPAT, HaGPAT9 isoform 1, with a N terminal peptide that possessed two phosphorylated residues with possible regulatory function. HaGPAT9-1 belongs to a broad eukaryotic GPAT family, similar to mammalian GPAT3, and it represents one of the two sunflower GPAT9 isoforms, sharing 90% identity with HaGPAT9-2. Both sunflower genes are expressed during seed development and in vegetative tissues, with HaGPAT9-1 transcripts accumulating at relatively higher levels than those for HaGPAT9-2. Green fluorescent protein tagging of HaGPAT9-1 confirmed its subcellular accumulation in the endoplasmic reticulum. Despite their overall sequence similarities, the two sunflower isoforms displayed significant differences in their enzymatic activities. For instance, HaGPAT9-1 possesses in vivo GPAT activity that rescues the lethal phenotype of the cmy228 yeast strain, while in vitro assays revealed a preference of HaGPAT9-1 for palmitoyl-, oleoyl- and linoleoyl-CoAs of one order of magnitude, with the highest increase in yield for oleoyl- and linoleoyl-CoAs. By contrast, no enzymatic activity could be detected for HaGPAT9-2, even though its over-expression modified the TAG profile of yeast. PMID- 27717478 TI - Physiological adjustments of a Mediterranean shrub to long-term experimental warming and drought treatments. AB - Warmer temperatures and extended drought in the Mediterranean Basin are becoming increasingly important in determining plant physiological processes and affecting the regional carbon budget. The responses of plant physiological variables such as shoot water potential (Psi), carbon-assimilation rates (A), stomatal conductance (gs) and intrinsic water-use efficiency (iWUE) to these climatic regimes, however, are not well understood. We conducted long-term (16 years) field experiments with mild nocturnal warming (+0.6 degrees C) and drought (-20% soil moisture) in a Mediterranean early-successional shrubland. Warming treatment moderately influenced Psi, A and gs throughout the sampling periods, whereas drought treatment strongly influenced these variables, especially during the summer. The combination of a natural drought in summer 2003 and the treatments significantly decreased A and iWUE. Foliar delta13C increased in the treatments relative to control, but not significantly. The values of Psi, A and gs were correlated negatively with vapor-pressure deficit (VPD) and positively with soil moisture and tended to be more dependent on the availability of soil water. The plant, however, also improved the acclimation to drier and hotter conditions by physiological adjustments (gs and iWUE). Understanding these physiological processes in Mediterranean shrubs is crucial for assessing further climate change impacts on ecosystemic functions and services. PMID- 27717479 TI - Mesophyll conductance and reaction-diffusion models for CO2 transport in C3 leaves; needs, opportunities and challenges. AB - One way to increase potential crop yield could be increasing mesophyll conductance gm. This variable determines the difference between the CO2 partial pressure in the intercellular air spaces (Ci) and that near Rubisco (Cc). Various methods can determine gm from gas exchange measurements, often combined with measurements of chlorophyll fluorescence or carbon isotope discrimination. gm lumps all biochemical and physical factors that cause the difference between Cc and Ci. gm appears to vary with Ci. This variability indicates that gm does not satisfy the physical definition of a conductance according to Fick's first law and is thus an apparent parameter. Uncertainty about the mechanisms that determine gm can be limited to some extent by using analytical models that partition gm into separate conductances. Such models are still only capable of describing the CO2 diffusion pathway to a limited extent, as they make implicit assumptions about the position of mitochondria in the cells, which affect the re assimilation of (photo)respired CO2. Alternatively, reaction-diffusion models may be used. Rather than quantifying gm, these models explicitly account for factors that affect the efficiency of CO2 transport in the mesophyll. These models provide a better mechanistic description of the CO2 diffusion pathways than mesophyll conductance models. Therefore, we argue that reaction-diffusion models should be used as an alternative to mesophyll conductance models, in case the aim of such a study is to identify traits that can be improved to increase gm. PMID- 27717480 TI - Soybean proteins GmTic110 and GmPsbP are crucial for chloroplast development and function. AB - We have identified a viable-yellow and a lethal-yellow chlorophyll-deficient mutant in soybean. Segregation patterns suggested single-gene recessive inheritance for each mutant. The viable- and lethal-yellow plants showed significant reduction of chlorophyll a and b. Photochemical energy conversion efficiency and photochemical reflectance index were reduced in the viable-yellow plants relative to the wildtype, whereas the lethal-yellow plants showed no electron transport activity. The viable-yellow plants displayed reduced thylakoid stacking, while the lethal-yellow plants exhibited failure of proplastid differentiation into normal chloroplasts with grana. Genetic analysis revealed recessive epistatic interaction between the viable- and the lethal-yellow genes. The viable-yellow gene was mapped to a 58kb region on chromosome 2 that contained seven predicted genes. A frame shift mutation, due to a single base deletion in Glyma.02g233700, resulted in an early stop codon. Glyma.02g233700 encodes a translocon in the inner membrane of chloroplast (GmTic110) that plays a critical role in plastid biogenesis. The lethal-yellow gene was mapped to an 83kb region on chromosome 3 that contained 13 predicted genes. Based on the annotated functions, we sequenced three potential candidate genes. A single base insertion in the second exon of Glyma.03G230300 resulted in a truncated protein. Glyma.03G230300 encodes for GmPsbP, an extrinsic protein of Photosystem II that is critical for oxygen evolution during photosynthesis. GmTic110 and GmPsbP displayed highly reduced expression in the viable- and lethal-yellow mutants, respectively. The yellow phenotypes in the viable- and lethal-yellow mutants were due to the loss of function of GmTic110 or GmPsbP resulting in photooxidative stress.

PMID- 27717481 TI - Abiotic stress upregulated TaZFP34 represses the expression of type-B response regulator and SHY2 genes and enhances root to shoot ratio in wheat. AB - Q-type C2H2 zinc finger proteins (ZFPs) are plant-specific DNA-binding proteins containing a conserved QALGGH motif. This study investigated the function of abiotic stress-inducible and predominantly root-expressed Triticum aestivum ZFPs (TaZFP22, TaZFP34 and TaZFP46) with a focus on TaZFP34. Expression of TaZFP34 in roots was upregulated by high salinity, dehydration, oxidative and cold stresses. Overexpression of TaZFP34 in wheat roots resulted in an increased root-to-shoot ratio, a phenomenon observed during plant adaptation to drying soil. Expression of a number of genes which are potentially involved in modulating root growth was significantly altered in the roots of TaZFP34 overexpressing lines. In particular, the transcript levels of TaRR12B, TaRR12D and TaSHY2 that are homologues of known negative regulators of root growth were significantly reduced. Expression of shoot growth-related genes, such as GA3-ox and expansins, was downregulated in the transgenic shoots. TaZFP34 bound to (C/G)AGT(G/A)-like elements in the promoters of TaZFP34 down-regulated TaRR12D and TaSHY2 and transrepressed the reporter gene expression driven by TaRR12D and TaSHY2 promoters. Expression of the above reporter genes was also repressed by TaZFP46 and TaZFP22. These data suggest that TaZFP34 is a transcriptional repressor and is involved in modulating the root-to-shoot ratio.

AB - Legionellosis is the common name for two infections, Legionnaires' disease (LD) and Pontiac fever (PF), both caused by Legionella bacteria. Although with low incidence, LD is an important cause of community- and hospital-acquired pneumonia. Among community-acquired cases, an increasing number was reported to be linked to the occupational setting, posing the need for better recognition of work activities at risk of legionellosis. In this work, we selected and reviewed relevant literature on cases of occupational legionellosis published between 1978 and 2016 in order to define the: i) etiology; ii) sources of infection, iii) work activities at risk, iv) infection rates, v) predisposing factors, vi) mortality and vii) country distribution. To our knowledge, this is the first review to provide an analysis of cases of occupational legionellosis. A literature search in the PubMed website was started on January 31, 2015 and ended on June 30, 2016. Cases of occupational legionellosis documented in the scientific literature were retrieved from PubMed upon interrogation with the following keywords: "Legionella pneumophila", "Legionnaires' disease", "Pontiac fever", and "legionellosis", in combination with "employees", "workers", and "occupational". Abstracts were reviewed, and applicable articles were obtained. Only articles that met the inclusion criteria were considered. Forty-seven articles were selected, reporting confirmed cases of legionellosis which occurred over 66 years (1949-2015), and involved 805 workers (221, LD; 584, PF). Fatalities were all associated with LD, resulting in 4.1% mortality. The most common etiologic agents were Legionella pneumophila (58.5%) and Legionella feeleii (39.4%), the latter being responsible for only one large outbreak of PF. Workplaces more frequently associated with occupational legionellosis were industrial settings (62.0%), office buildings (27.3%) and healthcare facilities (6.3%), though cases were also reported from a variety of workplaces, e.g. artesian excavation and horticultural sites, lorry parks, ships, water and sewage plants. With few exceptions, cases occurred in industrialized countries of the northern hemisphere. Overall, our review highlights an extended spectrum of occupational categories at risk for legionellosis. For all categories, infection originated from exposure to work generated aerosols contaminated with Legionella spp., and industrial facilities equipped with cooling towers or coolant systems were the most common occupational settings. These observations should raise awareness of the risk of acquiring legionellosis at work, and help to improve prevention and control measures for this infrequent but still problematic disease. PMID- 27717488 TI - Ten years since the discovery of iPS cells: The current state of their clinical application. AB - On the 10-year anniversary of the discovery of induced pluripotent stem cells, we review the main results from their various fields of application, the obstacles encountered during experimentation and the potential applications in clinical practice. The efficacy of induced pluripotent cells in clinical experimentation can be equated to that of human embryonic stem cells; however, unlike stem cells, induced pluripotent cells do not involve the severe ethical difficulties entailed by the need to destroy human embryos to obtain them. The finding of these cells, which was in its day a true scientific milestone worthy of a Nobel Prize in Medicine, is currently enveloped by light and shadow: high hopes for regenerative medicine versus the, as of yet, poorly controlled risks of unpredictable reactions, both in the processes of dedifferentiation and subsequent differentiation to the cell strains employed for therapeutic or experimentation goals. PMID- 27717487 TI - A survey to medical residents on the performance of diagnostic and therapeutic thoracenteses: a training gap? AB - OBJECTIVE: Pleural fluid aspiration is a routine procedure for pulmonologists and internists. Our aim was to evaluate technical and methodological aspects of diagnostic and therapeutic thoracenteses performed by last two-year residents of Pulmonology and Internal Medicine. METHODS: An online 24-item questionnaire was sent to participants, and responses were evaluated according to the medical specialty. RESULTS: The survey was completed by 139 (17.1%) residents (71 internists and 68 pulmonologists). 29.5% and 41% performed one or no diagnostic or therapeutic thoracenteses monthly, respectively. Only 44% used ultrasonography to guide pleural procedures. Less than half of respondents used local anesthesia for diagnostic aspirations. Contrary to current recommendations, 25% of residents employed intramuscular needles for therapeutic aspirations. More than 80% of residents routinely ordered pleural fluid cultures and cytological studies, regardless of the clinical suspicion. About 40% requested imaging studies after a diagnostic thoracentesis. Half or more of the respondents were unaware of pH measurement methodologies, culture type for mycobacteria, and performance of cell blocks. Pulmonologists were more experienced than internists, and also made use of ultrasonography more frequently. CONCLUSION: This survey highlights gaps of knowledge and skills in conducting diagnostic and therapeutic thoracenteses. PMID- 27717485 TI - Different components of blood pressure are associated with increased risk of atherosclerotic cardiovascular disease versus heart failure in advanced chronic kidney disease. AB - Blood pressure is a modifiable risk for cardiovascular disease (CVD). Among hemodialysis patients, there is a U-shaped association between blood pressure and risk of death. However, few studies have examined the association between blood pressure and CVD in patients with stage 4 and 5 chronic kidney disease. Here we studied 1795 Chronic Renal Insufficiency Cohort (CRIC) Study participants with estimated glomerular filtration rate <30 ml/min per 1.73 m2 and not on dialysis. The association of systolic (SBP), diastolic (DBP), and pulse pressure with the risk of physician-adjudicated atherosclerotic CVD (stroke, myocardial infarction, or peripheral arterial disease) and heart failure was tested using Cox regression adjusted for demographics, comorbidity and medications. There was a significant association with higher SBP (adjusted hazard ratio 2.04 [95% confidence interval: 1.46-2.84]) for SBP over 140 vs under 120 mmHg, higher DBP (2.52 [1.54-4.11]) for DBP >90 mm Hg versus <80 mm Hg and higher pulse pressure (2.67 [1.82-3.92]) for pulse pressure >68 mm Hg versus <51 mm Hg with atherosclerotic CVD. For heart failure, there was a significant association with higher pulse pressure only (1.42 [1.05-1.92]) for pulse pressure >68 mm Hg versus <51 mmHg, but not for SBP or DBP. Thus, among participants with stage 4 and 5 chronic kidney disease, there was an independent association between higher SBP, DBP, and pulse pressure with the risk of atherosclerotic CVD, whereas only higher pulse pressure was independently associated with a greater risk of heart failure. Further trials are needed to determine whether aggressive reduction of blood pressure decreases the risk of CVD events in patients with stage 4 and 5 chronic kidney disease.

AB - To get a better understanding of the bioactive constituents in Aurantii Fructus Immaturus (AFI) and Aurantii Fructus (AF), in the present study, a comprehensive strategy integrating multiple chromatographic analysis and chemometrics methods was firstly proposed. Based on segmental monitoring, a high-performance liquid chromatography (HPLC)-variable wavelength detection method was established for simultaneous quantification of ten major flavonoids, and the quantitative data were further analyzed by hierarchical cluster analysis (HCA) and principal component analysis (PCA). A strong cation exchange-high performance liquid chromatography (SCX-HPLC) method combined with t-test and one-way analysis of variance (ANOVA) was developed to determine synephrine, the major alkaloid in AFI and AF. The essential oils were analyzed by gas chromatography-mass spectrometry (GC-MS) and further processed by partial least squares discrimination analysis (PLS-DA). The results indicated that the contents of ten flavonoids and synephrine in AFI were significantly higher than those in AF, and significant difference existed in samples from different geographical origins. Also, 9 differential volatile constituents detected could be used as chemical markers for discrimination of AFI and AF. Collectively, the proposed comprehensive analysis might be a well-acceptable strategy to evaluate the quality of traditional citrus herbs. PMID- 27717491 TI - Location-independent analysis of structural progression of osteoarthritis-Taking it all apart, and putting the puzzle back together makes the difference. AB - OBJECTIVE: The metric accepted by regulatory bodies for determining structural progression in clinical trials of knee osteoarthritis (OA) remains change in radiographic joint space width in the medial femorotibial compartment. However, magnetic resonance imaging has revealed that cartilage loss is spatially heterogeneous, and that it is enigmatic which knee will lose cartilage at which location. Whereas previous reviews have focused on imaging in general, the purpose of this particular perspective is to highlight availability and applications of location-independent analysis methodology in measuring structural progression in epidemiological and interventional clinical trials, and to highlight its specific advantages over existing methodologies. METHODS: Narrative review/perspective based on a Pubmed search of original articles from 2009 to current. RESULTS: Ordering longitudinal change in subregion cartilage thickness by magnitude and direction, and averaging such ordered values or sums of negative and positive changes across knees is shown to be superior in detecting risk factors and interventional effects on structural progression of knee OA. Further, the methodology permits exploration of cartilage loss and gain simultaneously, phenomena that are missed when measurements are confined to cartilage volume or thickness loss in plates or compartments. CONCLUSIONS: Given spatial heterogeneity of cartilage loss in knee OA, location-independent analysis by MRI may provide opportunity for a paradigm shift. The authors recommend use of a location-independent metrices as the structural endpoints in epidemiological and intervention trials, particularly when examining anabolic and catabolic drug effects. Location-independent methods may be translated to analysis of cartilage composition and other articular tissues. PMID- 27717492 TI - Ignoring da Vinci and Darwin: The making of a better outlet valve. PMID- 27717490 TI - Brain metastases in patients with EOC: Clinico-pathological and prognostic factors. A multicentric retrospective analysis from the MITO group (MITO 19). AB - BACKGROUND: Brain metastases (BM) from epithelial ovarian cancer (EOC) are considered a rare and unfavourable event. There is no consensus regarding the best management of these patients. METHODS: A multicenter retrospective analysis of patients with BM from EOC treated between 1997 and 2014 in 18 institutions of the MITO (Multicenter Italian Trials in Ovarian cancer) group was conducted. Univariate and multivariate analysis were performed. RESULTS: A total of 174 women were identified as having BM from EOC. The median time interval between primary diagnosis of EOC and occurrence of BM was 26months (range 2-129months). The median overall survival from primary EOC diagnosis was 48months (95% CI 39.5 56.4months) and from diagnosis of BM was 12months (95% CI 9.6-14.3months). The majority of enrolled women (81.7%) were classified as sensitive to platinum-based chemotherapy. Four variables were significantly associated with poor overall survival in multivariate analysis: multiple BM [HR: 1.86 (95% CI: 1.22-2.84)], presence of extracranial disease [HR: 1.77 (95% CI: 1.11-2.83)] age [HR: 1.74 (95% CI: 1.17-2.59)], and monotherapy [HR: 2.57 (95% CI: 1.64-3.86)]. On the contrary, residual tumor at primary surgery, FIGO stage at primary diagnosis and platinum sensitivity were found to have no significant impact on survival from diagnosis of brain lesions. CONCLUSIONS: Our results suggest that BM is a rare and late manifestation of EOC, with a 12-month life-span expectation. Multiple approach is a positive independent prognostic factor and should be proposed to carefully selected patients.

AB - OBJECTIVES: To investigate physical activity levels in youth with multiple sclerosis and monophasic acquired demyelinating syndromes ([mono-ADS], ie, children without relapsing disease) compared with healthy controls and to determine factors that contribute to engagement in physical activity. We hypothesized that greater physical activity goal setting and physical activity self-efficacy would be associated with greater levels of vigorous physical activity in youth with multiple sclerosis. STUDY DESIGN: A total of 68 consecutive patients (27 multiple sclerosis, 41 mono-ADS) and 37 healthy controls completed fatigue, depression, Physical Activity Self-Efficacy Scale, perceived disability, Exercise Goal-Setting scale, and physical activity questionnaires, and wore an accelerometer for 7 days. All patients had no ambulatory limitations (Expanded Disability Status Scale, scores all <4). RESULTS: Youth with multiple sclerosis engaged in fewer minutes per day of vigorous (P = .009) and moderate and vigorous physical activity (P = .048) than did patients with mono-ADS and healthy controls. A lower proportion of the group with multiple sclerosis (63%) reported participating in any strenuous physical activity than the mono-ADS (85%) and healthy control (89%) groups (P = .020). When we adjusted for age and sex, the Physical Activity Self-Efficacy Scale and Exercise Goal-Setting scale were associated positively with vigorous physical activity in the group with multiple sclerosis. Fatigue and depression did not predict physical activity or accelerometry metrics. CONCLUSIONS: Youth with multiple sclerosis participate in less physical activity than their counterparts with mono-ADS and healthy controls. Physical activity self-efficacy and exercise goal setting serve as potentially modifiable correlates of physical activity, and are measures suited to future interventions aimed to increase physical activity in youth with multiple sclerosis.

In the recent WHO 2016 classification, pathology is enriched by localization and molecular biology. Whatever the age, total removal by one or several looks when required remains a major prognostic factor. In children, focal radiation remains a standard, while the role of chemotherapy is matter of randomized studies. In infants, front line chemotherapy is the standard. Inclusion in the SIOP ependymoma II protocol is encouraged. In case of relapse, further surgery and radiation are advised, while inclusion in innovative trials including re-irradiation, and phase I-II should be encouraged. A better understanding of underlying mechanisms of ependymoma cell will provide in the close future, the key to use targeted therapies at time of relapse, and very soon as first line therapy for some subgroups of patients.

AB - The tomato (Solanum lycopersicum L.) is one of the most important vegetables worldwide. Due to the limited genetic variability, wild related species are considered as potential gene pool for breeding cultivated plants with enriched genetic basis. Taxonomic relations between tomato species at the level of single groups and taxa still remain, however, not fully resolved. Hence, in addition to already reported classification based on the morphology of the plants and molecular markers, we proposed chemotaxonomic approach to unveil some aspects of tomato taxonomy. Cuticular hydrocarbons and surface sucrose esters (SEs) were used as chemotaxonomic markers. Classification based on the cuticular hydrocarbon profile was in good agreement with other taxonomic studies as long as between species differences were taken into account. Clear separation of the common tomato and closely related species from the majority of S. pennellii accessions was obtained. In the same time, however, S. pennellii revealed broad variation: based on the results, three highly distinct types of these plants were proposed, among them one type was very similar to cultivated tomato and its relatives. Addition of SEs profiles to the dataset did not impair the classification, but clarified the position of S. pennellii. The results suggest possible hybrid origin of some of S. pennellii and wild S. lycopersicum accessions, and the approach proposed has a potential to identify such hybrid plant lines. PMID- 27717502 TI - Single-center experience of stent retriever thrombectomy in acute ischemic stroke. AB - BACKGROUND AND PURPOSE: Recently, positive data from several randomized controlled trials (RCTs) of endovascular therapy for acute ischemic stroke (AIS) has emerged. The aim of this retrospective study is to present our clinical experience in cerebral vessel occlusion treatment using retrievable intracranial stents. METHODS: Forty-three consecutive patients with ischemic stroke (median age 75, range 22-87) treated by stent retriever thrombectomy (SolitaireTM FR) between January 2013 and December 2015 were identified. We retrospectively assessed Thrombolysis in Cerebral Infarction (TICI) scale (2b-3 considered as successful recanalization), clinical outcome using modified Rankin scale (mRs) at 3 months (regarding score 0-2 as good clinical outcome), device-related complications and symptomatic intracranial hemorrhage (sICH; parenchymal hematoma Type 1 or 2 and National Institutes of Health Stroke Scale [NIHSS] score increment >=4 points) rate. RESULTS: The mean NIHSS score on admission was 16.4 (median 16). The mean time from onset to groin puncture (time to treatment) was 290min (median 254min). Successful recanalization was achieved in 30 (69.8%) cases. The mean time from onset to successful reperfusion or procedure termination (time to reperfusion) was 394min (median 375min). Good outcome was observed in 17 (39.5%) patients and mortality was 27.9% (n=12). We found 2 (4,7%) sICHs, one (2,3%) thromboembolic event in different vascular territory and one (2,3%) groin hematoma. CONCLUSION: Stent retriever thrombectomy for the treatment of ischemic stroke is safe, provides high rate of recanalization and good clinical outcomes in the setting of large vessel occlusion.

PMID- 27717503 TI - BTLA-expressing CD11c antigen presenting cells in patients with active tuberculosis exhibit low capacity to stimulate T cell proliferation. AB - Despite past extensive studies on B and T lymphocyte attenuator (BTLA)-mediated negative regulation of T cell activation, the role of BTLA in antigen presenting cells (APCs) in patients with active pulmonary tuberculosis (ATB) remains poorly understood. Here, we demonstrate that BTLA expression on CD11c APCs increased in patients with ATB. Particularly, BTLA expression in CD11c APCs was likely associated with the attenuated stimulatory capacity on T cells (especially CD8+ T cell) proliferation. BTLA-expressing CD11c APCs showed lower antigen uptake capacity, lower CD86 expression, higher HLA-DR expression, and enhanced IL-6 secretion, compared to counterpart BTLA negative CD11c APCs in healthy controls (HC). Interestingly, BTLA-expressing CD11c APCs from ATB patients displayed lower expression of HLA-DR and less IL-6 secretion, but higher expression of CD86 than those from HC volunteers. Mixed lymphocyte reaction suggests that BTLA expression is likely associated with positive rather than conventional negative regulation of CD11c APCs stimulatory capacity. This role is impaired in ATB patients manifested by low expression of HLA-DR and low production of IL-6. This previous unappreciated role for BTLA may have implications in the prevention and treatment of patients with ATB. PMID- 27717505 TI - Emerging Field of Cardiomics: High-Throughput Investigations into Transcriptional Regulation of Cardiovascular Development and Disease. AB - Congenital heart defects remain a leading cause of infant mortality in the western world, despite decades of research focusing on cardiovascular development and disease. With the recent emergence of several high-throughput technologies including RNA sequencing, chromatin-immunoprecipitation-coupled sequencing, mass spectrometry-based proteomics analyses, and the numerous variations of these strategies, investigations into cardiac development have been transformed from candidate-based studies into whole-genome, -transcriptome, and -proteome undertakings. In this review, we discuss several reports that have emerged from our laboratory and others over the past 5 years that emphasize the versatility of large dataset-based investigations of cardiogenic transcription factors, from phenotypic validations and new gene implications to the identification of novel roles of well-studied transcriptional regulators.

AB - Targeting the epidermal growth factor receptor (EGFR) using tyrosine kinase inhibitors (TKIs) is highly effective in terms of tumor response rate, survival, and quality of life. However, acquired resistance to EGFR-TKIs is inevitable. Ongoing clinical trials will provide evidence for optimal strategies for patients with EGFR mutant non-small-cell lung cancer (NSCLC) in the near future. Numerous new agents are specifically addressing resistance mechanisms; mature data are related to the T790M mutation and MET pathway activation. Here, we provide a comprehensive review of new perspectives on how to optimize the management of this molecular disease.

PMID- 27717506 TI - The CRF System as a Therapeutic Target for Neuropsychiatric Disorders. AB - The major neuropsychiatric disorders are devastating illnesses that are only modestly responsive to treatment. Improving the treatment of these conditions will require innovative new strategies that depart from previously focused-on pharmacological mechanisms. Considerable preclinical and clinical data indicate corticotropin-releasing factor (CRF) signaling as a target for new psychotropic drug development. Here we review alterations in the CRF system reported in several psychiatric conditions. We also examine the preclinical work that has dissected the distinctive roles of CRF receptors in specific circuits relevant to these disorders. We further describe the clinical trials of CRF1 receptor antagonists that have been conducted. Although these clinical trials have thus far met with limited therapeutic success, the unfolding complexity of the CRF system promises many future directions for studying its role in the etiology and treatment of neuropsychiatric conditions.

PMID- 27717509 TI - Patterns of palliative care service consultation in a sample of critically ill ICU patients at high risk of dying. AB - OBJECTIVE: Describe patterns of palliative care service consultation among a sample of ICU patients at high risk of dying. BACKGROUND: Patients receiving mechanical ventilation (MV) face threats to comfort, social connectedness and dignity due to pain, heavy sedation and physical restraint. Palliative care consultation services may mitigate poor outcomes. METHODS: From a dataset of 1440 ICU patients with >=2 days of MV and >=12 h of sustained wakefulness, we identified those at high risk of dying and/or who died and assessed patterns of sub-specialty palliative care consultation. RESULTS: About half (773/1440 [54%]) were at high risk of dying or died, 73 (9.4%) of whom received palliative care consultation. On average, referral occurred after 62% of the ICU stay had elapsed. Primary reason for consult was clarification of goals of care (52/73 [72.2%]). CONCLUSIONS: Among MV ICU patients at high risk of dying, palliative care service consultation occurs late and infrequently, suggesting a role for earlier palliative care.

AB - INTRODUCTION: In patients with non-small cell lung cancer (NSCLC) treated with chemoradiotherapy (CRT), prophylactic cranial irradiation (PCI) is not standard practice. This study determined patient preferences for PCI with respect to survival benefit, reduction in brain metastases (BM) and acceptable toxicity. METHODS: A Discrete Choice Experiment was completed pre- and post-treatment. Patients made 15 hypothetical choices between two alternative PCI treatments described by four attributes: amount of life gained, chance of BM, ability to care for oneself, and loss of memory. Participants also chose between PCI and no PCI. RESULTS: 54 and 46 surveys were completed pre- and post-treatment. The most important attributes pre-treatment were: a survival benefit >6months, of 3 6months, avoiding severe problems with memory and self-care, avoiding quite a bit of difficulty with memory and maximally reducing BM recurrence. Post-treatment, BM reduction became more important. 90% of patients would accept PCI for a survival benefit >6months, with a maximal reduction in BM even if severe memory/self-care problems occurred. With a 10% reduction in BM and mild problems with memory and self-care 70% of patients pre- (90% post-treatment) would accept PCI for a survival benefit of 1-3months, and 52% pre- (78% post-treatment) for no survival benefit. CONCLUSION: Improvement in survival is the most important attribute of PCI with patients willing to accept significant toxicity for maximum survival and less toxicity for less survival benefit. BM reduction became more important after treatment. The majority of patients would accept PCI for no survival benefit and a reduction in BM.

AB - The clinical spectrum of Ebola virus disease (EVD) ranges from very serious forms with organ failure and death within days to paucisymptomatic forms and perhaps even asymptomatic. The authors propose a focus on the clinical manifestations of EVD, on prognosis and on therapeutic aspects (excluding resuscitation). This work extracts from the literature the main data gathered during the 2014-2015 epidemic that raged in Guinea Conakry and Sierra Leone. These two countries, even if they are separated by a border, are one and the same population base. The characteristics of the epidemic in Liberia have not been analyzed. The authors have treated EVD patients in the health workers treatment center of Conakry and enrich this work about their personal experience. PMID- 27717514 TI - Adhesion of living cells to abutment materials, dentin, and adhesive luting cement with different surface qualities. AB - OBJECTIVE: We tested the adhesion properties of living gingival fibroblasts on three different implant abutment materials, adhesive resin used to bond bi partite abutments, and human dentin. METHODS: Discs of lithium disilicate (LS), zirconium dioxide (Zr), adhesive resin cement (AR), titanium (Ti), and human dentin (HD) were fabricated with three different levels of surface roughness (rough, machined, and polished). Ra and Rz, water contact angle, and cell detachment forces were measured. Cell detachment force was measured for single cells using single-cell force spectroscopy. Data were statistically analyzed using parametric tests (ANOVA, MANOVA, Bonferroni post-hoc tests). RESULTS: Surface roughness significantly influenced the water contact angle for all materials (P<=0.05). Overall, HD showed the lowest contact angle, followed by LS, Ti, Zr, and AR (P<=0.05). Comparison of cell detachment forces between materials with rough and machined surfaces revealed no significant differences (P>0.05), with the exception of Zr compared to HD with rough surfaces (P=0.006). For polished surfaces, HD showed the highest detachment force (P<=0.0001), followed by Ti, AR, and Zr, which did not significantly differ from each other (P>0.05) and LS; Ti/AR was significantly different from LS (P<=0.05). Except for HD, where polished surfaces exhibited the highest cell detachment force (P<=0.002), most machined surfaces showed higher cell detachment forces than polished or rough surfaces. SIGNIFICANCE: Implant abutments should ideally be provided with a machined like surface roughness for best cell adhesion. PMID- 27717515 TI - Shear-Wave Elastography: Could it be Helpful for the Diagnosis of Non-Mass-Like Breast Lesions? AB - The goal of this study was to analyze the diagnostic performance of shear wave elastography (SWE) in differentiation of benign and malignant non-mass-like (NML) breast lesions. Three hundred sixteen consecutive breast lesions in 305 patients who have been scheduled for ultrasound (US)-guided core needle biopsy or vacuum assisted biopsy or surgical excision between January 2013 and August 2013 were initially included in this study. Finally, 63 patients with 67 lesions classified as NML lesions comprised our study population. The features of SWE and its diagnostic performance in NML lesions were analyzed. Among the 67 NML lesions, 33 were malignant and 34 were benign. The maximum elastic modulus, mean elastic modulus, minimum elastic modulus, elastic modulus ratio and stiff rim sign of the malignant lesions were all significantly higher than those of benign lesions (p < 0.05). The combination of conventional US with maximum elastic modulus and stiff rim sign got significantly higher diagnostic specificity and positive predictive value (PPV) than conventional US (p < 0.05 for both). In the benign lesions, 23 (67.6%) unnecessary biopsies could have been eliminated after the combination of conventional US and SWE. SWE could increase diagnostic specificity and positive predictive values of NML breast lesions. The combination of conventional US and SWE could reduce unnecessary benign biopsies of NML lesions. PMID- 27717516 TI - Ambient Pressure Evaluation Through Sub-Harmonic Response of Chirp-Sonicated Microbubbles. AB - The sub-harmonic response generated by oscillating ultrasound contrast microbubbles has been proven to be a potentially efficient and effective measure for non-invasive blood pressure evaluation. In this work, an improved approach to ambient pressure measurement is proposed, and the general principle underlying this approach is the combination of sub-harmonic responses of microbubbles with a chirp excitation technique. Agreement between theoretical and experimental studies indicates that compared with sinusoidal excitation, the chirp technique is beneficial in that it produces bubble sub-harmonics with higher amplitudes and lower generation thresholds and thus offers better sensitivity for ambient pressure evaluations. Studies that took the chirp parameters (e.g., central frequency, bandwidth and pulse length) into account were also carried out to determine an optimized routine for the proposed method. PMID- 27717518 TI - Hypersensitivity to aspirin and urgent percutaneous coronary intervention: A therapeutic challenge. AB - Hypersensitivity reactions to nonsteroidal anti-inflammatory drugs are common and five types of reactions have been defined. The prevalence of such reactions in patients with myocardial infarction is unclear, and so antiplatelet therapy in this population is a challenge. Various desensitization protocols have been developed but there are no specific guidelines for their use. The authors present the case of a patient with acute coronary syndrome and aspirin hypersensitivity referred for urgent coronary angiography. Aspirin desensitization therapy is safe and successful in many patients, but more randomized trials are needed to confirm its benefits in coronary artery disease patients. PMID- 27717517 TI - Youth Acquisition and Situational Use of Cigars, Cigarillos, and Little Cigars:: A Cross-sectional Study. AB - INTRODUCTION: Although adolescent use of cigars, cigarillos, and little cigars (CCLCs) has been increasing, little research has been conducted to understand how adolescents acquire CCLCs and the situations in which they smoke CCLCs. Thus, this study aims to understand how adolescent smokers acquire CCLCs and the situations in which they smoke them. METHODS: Data were drawn from the 2011 Cuyahoga County Youth Risk Behavior Survey. Current CCLC smoking was assessed; analysis was limited to current smokers (n=1,337). Current users were asked to identify situations in which they use cigars and ways in which they get cigars. Bivariate analyses assessed differences by sex, race, and concurrent substance use. Data were analyzed in 2014. RESULTS: Youth acquired CCLCs most commonly by buying (64.2%). CCLC smokers also reported high rates of social use (81.1%). There were no significant differences is situational use across sexes, but female adolescents were significantly more likely than male adolescents to share CCLCs and significantly less likely to buy or take CCLCs. Conversely, significant differences were seen for situational use by race/ethnicity, with whites significantly more likely to use in social situations and less likely to use in solitary situations versus blacks and Hispanics. Finally, significant differences were observed in both acquisition and use for youth who concurrently used CCLCs and cigarettes compared with CCLCs only; fewer differences were noted among those who concurrently used CCLCs and marijuana compared with CCLCs only. CONCLUSIONS: These findings highlight how adolescents acquire and use CCLCs and can inform tobacco control strategies to prevent and reduce CCLC use. PMID- 27717519 TI - Central pressures and central hemodynamic values in white coat hypertensives are closer to those of normotensives than to those of controlled hypertensives for similar age, gender, and 24-h and nocturnal blood pressures. AB - INTRODUCTION: There is disagreement whether white coat hypertensives (WCH) have different hemodynamic and structural characteristics compared to normotensives (NT) and hypertensives (HT). METHODS: We compared cardiovascular prognostic markers (pulse wave velocity [PWV] and aortic stiffness index [ASI]) and data on central hemodynamics and central pressures (augmentation index [AIx], augmentation pressure [AugP] and pulse pressure amplification [PPA]) from aortic pulse wave analysis between NT (n=175), WCH (n=315) and treated HT (n=691), all with 24-h blood pressure (BP) <130/80 and nocturnal BP <120/70 mmHg after matching for age, gender, body mass index (BMI) and and nocturnal BP. The groups were also compared separately in terms of 24-h systolic BP <120 mmHg and 120-129 mmHg. RESULTS: The percentage of non-dippers was 40.1% in NT, 34.5% in WCH and 38.3 in HT. For similar 24-h and nocturnal systolic BP (NT 109/64+/-7/5, WCH 110/66+/-7/6, HT 109/64+/-7/5 mmHg), aortic stiffness was greater in HT (n=691, PWV 10.8+/-2.6 m/s and ASI 0.33+/-0.16, p<0.01) than in WCH (n=316, PWV 9.7+/-2.4 m/s and ASI 0.28+/-0.17) and NT (n=175, PWV 9.5+/-2.0 m/s and ASI 0.29+/-0.15); AugP and AIx were higher (p<0.01) in HT (13.9+/-8.2 and 29.6+/-12.6 mmHg) than in WCH (11.5+/-8.5 mmHg and 24.9+/-15.2) and NT (11.0+/-6.4 mmHg and 26.6+/-11.5). PPA was lower (p<0.01) in HT (11.3+/-5.5 mmHg) than in WCH (13.2+/-7.1 mmHg) and in NT (12.4+/-4.9 mmHg). The findings were similar when the 24-h systolic BP <120 mmHg and 120-129 mmHg subgroups were analyzed separately. CONCLUSION: Our data suggest that for similar age, gender distribution, BMI, and 24-h and nocturnal BP, aortic stiffness, central aortic pressures and wave reflection in WCH are closer to those of NT than to those with treated HT. This supports the idea that white coat hypertension may be a more benign condition than treated hypertension for similar 24-h and particularly nocturnal BP levels.

AB - Coronin 1, a member of the evolutionary conserved WD repeat protein family of coronin proteins is expressed in all leukocytes, but a role for coronin 1 in natural killer (NK) cell homeostasis and function remains unclear. Here, we have analyzed the number and functionality of NK cells in the presence and absence of coronin 1. In coronin 1-deficient mice, absolute NK cell numbers and phenotype were comparable to wild type mice in blood, spleen and liver. Following in vitro stimulation of the activating NK cell receptors NK1.1, NKp46, Ly49D and NKG2D, coronin 1-deficient NK cells were functional with respect to interferon-gamma production, degranulation and intracellular Ca2+ mobilization. Also, both wild type as well as coronin 1-deficient NK cells showed comparable cytotoxic activity. Furthermore, activation and functionality of NK cells following Vesicular Stomatitis Virus (VSV) infection was similar between wild type and coronin 1-deficient mice. Taken together these data suggest that coronin 1 is dispensable for mouse NK cell homeostasis and function. PMID- 27717522 TI - Comparative Effectiveness of Newer Medications for Lower Urinary Tract Symptoms Attributed to Benign Prostatic Hyperplasia: A Systematic Review and Meta analysis. AB - CONTEXT: Alpha-blockers (ABs) and 5-alpha reductase inhibitors have an established role in treating male lower urinary tract symptoms (LUTS) attributed to benign prostatic hyperplasia (BPH). Recently, newer drugs have shown promise for this indication. OBJECTIVE: To assess the comparative effectiveness and adverse effects (AEs) of newer drugs to treat LUTS attributed to BPH through a systematic review and meta-analysis. EVIDENCE ACQUISITION: Ovid MEDLINE, the Cochrane Central Register of Controlled Trials, and Ovid Embase bibliographic databases (through June 2016) were hand searches for references of relevant studies. Eligible studies included randomized controlled trials published in English of newer ABs, antimuscarinics, a beta-3 adrenoceptor agonist, phosphodiesterase type-5 inhibitors, or combination therapy with one of these medications as an active comparator. Observational studies of the same agents with a duration >=1 yr that reported AEs were also included. EVIDENCE SYNTHESIS: We synthesized evidence from 43 randomized controlled trials as well as five observational studies. Based on improvement of mean International Prostate Symptom Score and quality of life scores, the effectiveness of the newer ABs was not different from the older ABs (moderate strength of evidence [SOE]), but had more AEs (low SOE). Antimuscarinics/AB combination therapy had similar outcomes as AB monotherapy (all moderate SOE), but often had more AEs. Phosphodiesterase type-5 inhibitors alone or in combination with ABs had similar or inferior outcomes than ABs alone. Evidence was insufficient for the beta-3 adrenoceptor agonist. For all newer agents, the evidence was generally insufficient to assess long-term efficacy, prevention of symptom progression, or AEs. CONCLUSIONS: None of the drugs or drug combinations newly used to treat LUTS attributed to BPH showed outcomes superior to traditional AB treatment. Given the lack of superior outcomes, the studies' short time-horizon, and less assurance of their safety, their current value in treating LUTS attributable to BPH appears low. PATIENT SUMMARY: In this paper, we reviewed the evidence of newer drugs to treat men with urinary problems attributable to an enlarged prostate. We found none of the new drugs to be better but there was more concern about side effects. PMID- 27717524 TI - STA-21, a STAT-3 inhibitor, attenuates the development and progression of inflammation in collagen antibody-induced arthritis. AB - We set out to investigate the influence of STA-21, a dynamic STAT-3 inhibitor, on the expansion and progression of rheumatoid arthritis (RA), and to determine its potential mechanisms of action in a mouse model of collagen antibody-induced arthritis (CAIA). To this end, arthritis was induced via intravenous (IV) injection of Balb/c mice with a cocktail of antibodies directed against type II collagen (1.5MUg/mouse, IV), followed by lipopolysaccharide (LPS) at a dose of (25MUg/mouse, i.p.) on day 3. Mice were then left untreated or were simultaneously treated with STA-21 (0.5mg/kg, i.p., once daily for 2 weeks) followed by evaluation for clinical and histological features of arthritic inflammation and flow cytometric analysis of cytokines and transcription factors in peripheral blood. STA-21 enhanced the clinical course of arthritis in CAIA mice and decreased CD8+RORgammat+ and CD8+IL-21+ cells while inducing the production of CD8+Foxp3+ cells. Furthermore, STA-21 prevented the production of TNF-alpha and IL-6 in peripheral blood and increased IL-27 production by CD14+ cells. Moreover, STA-21 not only regulates Th1/Th2 serum cytokine levels but also the mRNA and protein expression of key factors including NF-kappaB p65, RORgammat, T-bet, IL-4, GATA-3, JAK1, Stat3, and IL-21. Thus, administration of the Stat3 inhibitor STA-21 inhibits cellular signaling pathways and downstream activation of key transcription factors previously shown to play key roles in the pathogenesis of RA. Therefore, these data suggest that STA-21 could be considered as a potential treatment for patients with RA.

AB - : Brucellosis is a bacterial zoonotic disease mainly transmitted to humans by ruminants. In France, brucellosis has disappeared from ruminants herds. Human brucellosis surveillance is performed through mandatory notification and the national reference center. METHODS: We report the results of human brucellosis surveillance from 2004 to 2013 with regards to epidemiological, clinical and microbiological data. RESULTS: A total of 250 cases were notified, making an annual incidence of 0.3 cases per million inhabitants. Brucella melitensis biovar 3 was the most frequently identified bacterium (79% of isolated strains). In total, 213 (85%) cases had been contaminated abroad in endemic countries. In 2012, an episode of re-emergence of brucellosis in cattle occurred in Haute Savoie, in the French Alps, and was responsible for 2 human cases. CONCLUSION: Brucellosis has become a disease of travelers in France. However, maintaining a stringent epidemiological surveillance is necessary to be able to early detect any local re-emergence in humans or animals. The multidisciplinary surveillance was implemented in France years ago and is a successful example of the One Health Concept. PMID- 27717527 TI - Association of Traumatic and Atraumatic Posterior Shoulder Instability With Glenoid Retroversion and Outcomes After Arthroscopic Capsulolabral Repair. AB - PURPOSE: To compare glenoid retroversion and functional outcomes between patients with traumatic onset of posterior shoulder instability (PSI) and patients with atraumatic onset of PSI. METHODS: Patients with PSI who underwent arthroscopic posterior capsulolabral anchor repair, were active in sports, and had undergone surgery a minimum of 2 years earlier were included. Traumatic onset was defined as PSI that occurred after a trauma with the shoulder in adduction, flexion, and internal rotation in patients with no history of instability. Subjective evaluations were obtained with the American Shoulder and Elbow Surgeons (ASES); Quick Disabilities of the Arm, Shoulder and Hand; Single Assessment Numeric Evaluation (SANE); and Short Form 12 Physical Component Summary scores preoperatively and after a minimum 2-year follow-up postoperatively. Additional questions assessed return to sport and shoulder stability. Glenoid version was measured with a 2-dimensional glenoid vault method on magnetic resonance imaging. RESULTS: A total of 41 shoulders in 38 patients were eligible for inclusion (3 female and 35 male patients; mean age, 27.6 years; age range, 13 to 66 years). Three patients refused participation, and 2 patients required subsequent surgery for failure. Postoperative outcomes were available for 32 of the remaining 36 shoulders (89%) with a mean follow-up of 4.1 years (range, 2.0 to 7.8 years; 20 atraumatic and 12 traumatic). The ASES score improved significantly in both groups (P < .03), whereas the SANE; Quick Disabilities of the Arm, Shoulder and Hand; and Short Form 12 Physical Component Summary scores only significantly improved for patients with traumatic PSI (P < .02). Baseline score-adjusted comparison between groups showed that the postoperative median ASES scores (atraumatic, 95.8; traumatic, 99.9) and SANE scores (atraumatic, 86.5; traumatic, 98.0) were significantly more improved in patients with traumatic PSI (P = .01 and P = .012, respectively). Atraumatic PSI was associated with significantly higher glenoid retroversion (-21.8 degrees +/- 4.2 degrees vs -17.7 degrees +/ 5.5 degrees , P = .032). There was no significant difference regarding return to sport (P = .375) or postoperative re-dislocations (P = .99) between the groups. CONCLUSIONS: Atraumatic onset of PSI was associated with higher degrees of glenoid retroversion and less favorable functional outcomes of arthroscopic posterior capsulolabral anchor repair than traumatic PSI. LEVEL OF EVIDENCE: Level III, retrospective case-control study. PMID- 27717528 TI - Inferior mesenteric artery lymph node metastasis in rectal cancer treated with neoadjuvant chemoradiotherapy: Incidence, prediction and prognostic impact. AB - AIM: To assess the effect of neoadjuvant chemoradiotherapy (nCRT) on inferior mesenteric artery (IMA) nodal metastasis and identify predictors for IMA nodal metastasis in locally advanced rectal cancer (LARC) after nCRT. METHOD: Propensity score matching of 1167 patients with LARC was performed. Clinicopathological predictors and survival rates were analyzed using univariate and multivariate analyses. RESULTS: Compared to surgery alone, nCRT reduced the incidence of IMA nodal metastasis (before matching, 4.8% vs 9.1%, p = 0.004; after matching, 4.3% vs 10.1%, p = 0.002). Logistic regression analysis revealed that poorly differentiated (OR = 5.955, p < 0.001), tumors located above the peritoneal reflection (OR = 3.513, p = 0.005), and preoperative CEA levels ?10 ng/ml (OR = 4.774, p = 0.005) were associated with IMA nodal metastasis. Time intervals to surgery ?6 weeks were associated with fewer IMA nodal metastasis (OR = 0.274, p = 0.009).Over a median 40-month follow-up, the 3-year overall survival and disease-free survival rates were 63.0% and 43.1% in IMA-positive patients, respectively, which were significantly lower than the corresponding 89.0% and 82.4% rates in IMA-negative patients. Cox regression analysis revealed that IMA nodal metastasis was independently associated with unfavorable 3-year DFS. CONCLUSION: nCRT reduced the incidence of IMA node metastasis. Tumors located above the peritoneal reflection, poorly differentiated, and higher preoperative CEA levels were associated with IMA nodal metastasis after nCRT. IMA lymph node dissection is beneficial to certain patients with IMA nodal metastases, and the oncologic benefit may be improved if IMA nodal metastasis can be predicted. PMID- 27717529 TI - Individualizing surgical treatment based on tumour response following neoadjuvant therapy in T4 primary rectal cancer. AB - BACKGROUND: Rectal cancer involving at least one adjacent organ (mrT4b) requires multi-visceral resection to achieve clear resection margin (R0). Performing pelvic compartment preservation according to the tumour response has not been considered. This study assesses the impact of changing the surgical strategy according to tumour response in rectal cancer mrT4b. METHODS: Patients with non metastatic T4b rectal cancer at two tertiary referral centres between 2008 and 2013 were grouped as "Responders" ypT0-3abNx versus "Non-responders" ypT3cd-4Nx and divided into three surgical procedures: total mesorectal excision (TME), extended-TME (eTME) and beyond-TME (b-TME). End-points were circumferential resection margin, postoperative morbidity, definitive stoma formation, 3-years local recurrence (3y-LR) and 3-years disease-free survival (3y-DFS) according to both tumours' response and surgical procedures. RESULTS: Among 883 patients with rectal cancer, 101 were included. Responders had a higher rate of induction chemotherapy (59.7% vs. 38.2%; p = 0.04). Morbidity and definitive stoma formation were significantly higher in Non-responders. R0 was not impacted by either the tumour response or the surgical procedures. The 3y-LR was lower in Responders (14%) compared to Non Responders (32%) (HR 1.6; 95% CI: 1.02-2.59; p = 0.041), and was two-fold higher in e-TME compared to b-TME in Non-responders, whereas no difference was found in Responders. The 3y-DFS was higher in Responders irrespective to the surgery (71% vs. 47%; p = 0.07). CONCLUSION: In Responders, TME or e-TME are technically and oncollogically feasible and should be considered in preferrence to b-TME. In Non-responders, allowing for high rates of morbidity and local recurrence in patients with e-TME, b-TME procedures should be preferred. PMID- 27717530 TI - Effect of silver nano-particles on soil microbial growth, activity and community diversity in a sandy loam soil. AB - Silver nano-particles (AgNPs) are widely used in a range of consumer products as a result of their antimicrobial properties. Given the broad spectrum of uses, AgNPs have the potential for being released to the environment. As a result, environmental risks associated with AgNPs need to be assessed to aid in the development of regulatory guidelines. Research was performed to assess the effects of AgNPs on soil microbial activity and diversity in a sandy loam soil with an emphasis on using a battery of microbial tests involving multiple endpoints. The test soil was spiked with PVP coated (0.3%) AgNPs at the following concentrations of 49, 124, 287, 723 and 1815 mg Ag kg-1 dry soil. Test controls included an un-amended soil; soil amended with PVP equivalent to the highest PVP concentration of the coated AgNP; and soil amended with humic acid, as 1.8% humic acid was used as a suspension agent for the AgNPs. The impact on soil microbial community was assessed using an array of tests including heterotrophic plate counting, microbial respiration, organic matter decomposition, soil enzyme activity, biological nitrification, community level physiological profiling (CLPP), Ion TorrentTM DNA sequencing and denaturing gradient gel electrophoresis (DGGE). An impact on microbial growth, activity and community diversity was evident from 49 to 1815 mg kg-1 with the median inhibitory concentrations (IC50) as low as 20-31 mg kg-1 depending on the test. AgNP showed a notable impact on microbial functional and genomic diversity. Emergence of a silver tolerant bacterium was observed at AgNP concentrations of 49-287 mg kg-1 after 14-28 days of incubation, but not detectable at 723 and 1815 mg kg-1. The bacterium was identified as Rhodanobacter sp. The study highlighted the effectiveness of using multiple microbial endpoints for inclusion to the environmental risk assessment of nanomaterials. PMID- 27717531 TI - Size distribution of stranded small plastic debris on the coast of Guangdong, South China. AB - Beach environments are known to be conducive to fragmentation of plastic debris, and highly fragmented plastic particles can interact with smaller organisms. Even through stranded plastic debris may not interact directly with marine organisms, backwash processes may transport this debris back to coastal waters, where it may affect a wide range of marine life at different trophic levels. This study analysed the size distribution of stranded plastic debris (<10 mm) collected from eight coastal beaches in Guangdong Province, China. Polystyrene (PS) foams and fragments smaller than 7 mm were increasingly abundant in the smaller size classes, whereas resin pellets remained in their production sizes (~3 mm). Microplastics (<5 mm) accounted for over 98% of the total plastic debris by abundance and 71% by weight, indicating that the plastic debris on these coastal beaches was highly fragmented and the majority of the plastic masses belonged to the microplastic size range. The observed size distributions of PS foams and fragments are believed to result from continued fragmentation. Previous studies found that the residence time of beached debris was less than one year on average, and no sign of plastic accumulation with depth in beach sediment was observed. Therefore, coastal beaches may represent a reservoir of highly fragmented and degraded microplastics that may be mobilised and returned to the sea during storm events. Further research on the dynamics and longevity of microplastics on beaches will help reveal the mass balance of microplastics on the shoreline and determine whether shorelines are sinks or sources of microplastics. PMID- 27717533 TI - Creating Age Asymmetry: Consequences of Inheriting Damaged Goods in Mammalian Cells. AB - Accumulating evidence suggests that mammalian cells asymmetrically segregate cellular components ranging from genomic DNA to organelles and damaged proteins during cell division. Asymmetric inheritance upon mammalian cell division may be specifically important to ensure cellular fitness and propagate cellular potency to individual progeny, for example in the context of somatic stem cell division. We review here recent advances in the field and discuss potential effects and underlying mechanisms that mediate asymmetric segregation of cellular components during mammalian cell division. PMID- 27717532 TI - Decision-making and goal-setting in chronic disease management: Baseline findings of a randomized controlled trial. AB - OBJECTIVE: Growing interest in collaborative goal-setting has raised questions. First, are patients making the 'right choices' from a biomedical perspective? Second, are patients and providers setting goals of appropriate difficulty? Finally, what types of support will patients need to accomplish their goals? We analyzed goals and action plans from a trial of collaborative goal-setting among 302 residents of a high-poverty urban region who had multiple chronic conditions. METHODS: Patients used a low-literacy aid to prioritize one of their chronic conditions and then set a goal for that condition with their primary care provider. Patients created patient-driven action plans for reaching these goals. RESULTS: Patients chose to focus on conditions that were in poor control and set ambitious chronic disease management goals. The mean goal weight loss -16.8lbs (SD 19.5), goal HbA1C reduction was -1.3% (SD 1.7%) and goal blood pressure reduction was -9.8mmHg (SD 19.2mmHg). Patient-driven action plans spanned domains including health behavior (58.9%) and psychosocial (23.5%). CONCLUSIONS: High risk, low-SES patients identified high priority conditions, set ambitious goals and generate individualized action plans for chronic disease management. PRACTICE IMPLICATIONS: Practices may require flexible personnel who can support patients using a blend of coaching, social support and navigation. PMID- 27717534 TI - Piecing Together the Patchwork of Contact Sites. AB - Contact sites are places where two organelles join together to carry out a shared activity requiring nonvesicular communication. A large number of contact sites have been discovered, and almost any two organelles can contact each other. General rules about contacts include constraints on bridging proteins, with only a minority of bridges physically creating contacts by acting as 'tethers'. The downstream effects of contacts include changing the physical behaviour of organelles, and also forming biochemically heterogeneous subdomains. However, some functions typically localized to contact sites, such as lipid transfer, have no absolute requirement to be situated there. Therefore, the key aspect of contacts is the directness of communication, which allows metabolic channelling and collective regulation. PMID- 27717535 TI - Trends in major opioid analgesic consumption in Taiwan, 2002-2014. AB - BACKGROUND/PURPOSE: According to WHO guideline, the consumption of opioids is an important sign of national progress in cancer pain relief. However, precise data on the consumption of opioid analgesics consumption in Taiwan has not been published. We investigate opioid analgesic consumption in Taiwan between 2002 and 2014 compare the results with those in other countries to see what we could learn about other methods of pain management. To find out the different patterns between Taiwan and other country, improves the quality of pain management. METHODS: We extracted from the Controlled Drugs Management Information System (CDMIS) database, the consumption data of morphine, fentanyl, and pethidine, three strong opioids, and of codeine and buprenorphine, two weak ones. Data were presented as defined daily doses for statistical purposes per million inhabitants per day (S-DDD/m/d). The number of inhabitants was extracted from the Taiwan Ministry of Interior Statistics population database. RESULTS: During the thirteen studied years, the total consumption of opioids markedly increased in Taiwan. By category, the consumption of morphine, fentanyl and buprenorphine increased, but the use of pethidine and codeine decreased. Compared with the selected regions and countries, the use of opioid in Taiwan progressed in Asia, but it was still lower than in Western countries. CONCLUSION: Opioid analgesics are probable addictive; however, they can improve a patients' quality of life if properly used. The Taiwan FDA continuously introduces new opioid analgesics and educates physicians on how to use them correctly. These measures will improve the quality of pain management in Taiwan. PMID- 27717536 TI - The hypoxia-inducible factor (HIF) couples immunity with metabolism. AB - Crosstalk between metabolic and immune pathways has recently become appreciated to be key to the regulation of host defence. The hypoxia-inducible factor (HIF) is a transcription factor which was initially described as a ubiquitous master regulator of the transcriptional response to hypoxia. In this role, HIF regulates genes promoting adaptation to hypoxia including a number which influence the cellular metabolic strategy of a cell. It has more recently been appreciated that the regulation of HIF is not restricted to oxygen-dependent pathways, and is now known to be mediated by a number of additional metabolic and immune cues including metabolites and cytokines respectively. Furthermore, our understanding of the functional role of HIF has expanded to it now being appreciated as a major regulator of host immunity. This places HIF in an ideal position to act as a regulatory hub which links metabolic activity with immunity. In this review we synthesise recent data which identifies HIF as both a target and effector for metabolic and immune processes. Developing our understanding of the role of HIF in this context will uncover new therapeutic targets for inflammatory and infectious disease.

PMID- 27717539 TI - Is Heart Disease or Cancer the Leading Cause of Death in United States Women? AB - PURPOSE: This paper compares the mortality burden of heart disease versus cancer among women by age, race, and ethnicity. METHODS: U.S. death and population data for the years 2000 through 2013 were used to calculate heart disease and cancer death rates. Detailed analyses focused on age (15-19 years old to >=100 years old) and race and ethnicity (Whites, Blacks, Hispanics, Asians and Pacific Islanders (A/PIs), and American Indians and Alaska Natives (AI/ANs)). RESULTS: Among women aged 15 years and older, there were 289,467 heart disease deaths and 276,716 cancer deaths in 2013. The majority of heart disease deaths (51.6%) occurred among women 85 years or older, compared with 18.9% of female cancer deaths. The age-adjusted death rates (per 100,000 population) were 171 (95% confidence interval [CI], 170-171) for heart disease versus 177 (95% CI, 176-178) for cancer. For all racial and ethnic groups, cancer mortality was significantly higher than heart disease mortality among women younger than 80 years of age. For all ages combined, cancer deaths exceeded heart disease deaths among Hispanics, A/PIs, and AI/ANs. Black non-Hispanic women were the only racial/ethnic group who had a higher age-adjusted death rate for heart disease than for cancer: 224 (95% CI, 222-226) versus 207 (95% CI, 205-209). CONCLUSIONS: Heart disease remains the leading cause of death among all women combined in the United States by a narrow margin. However, cancer predominantly kills middle-aged and young women, whereas heart disease predominantly kills the very old. New research on the overreporting of heart disease on death certificates for elderly women is needed. National summary statistics obscure the fact that cancer is already the overall leading cause of death for Hispanic women, Asian and Pacific Islander women, and American Indian and Alaska Native women. PMID- 27717538 TI - Non-invasive assessment of low- and intermediate-risk patients with chest pain. AB - Coronary artery disease (CAD) remains a significant global public health burden despite advancements in prevention and therapeutic strategies. Common non invasive imaging modalities, anatomic and functional, are available for the assessment of patients with stable chest pain. Exercise electrocardiography is a long-standing method for evaluation for CAD and remains the initial test for the majority of patients who can exercise adequately with a baseline interpretable electrocardiogram. The addition of cardiac imaging to exercise testing provides incremental benefit for accurate diagnosis for CAD and is particularly useful in patients who are unable to exercise adequately and/or have uninterpretable electrocardiograms. Radionuclide myocardial perfusion imaging and echocardiography with exercise or pharmacological stress provide high sensitivity and specificity in the detection and further risk stratification of patients with CAD. Recently, coronary computed tomography angiography has demonstrated its growing role to rule out significant CAD given its high negative predictive value. Although less available, stress cardiac magnetic resonance provides a comprehensive assessment of cardiac structure and function and provides a high diagnostic accuracy in the detection of CAD. The utilization of non-invasive testing is complex due to various advantages and limitations, particularly in the assessment of low- and intermediate-risk patients with chest pain, where no single study is suitable for all patients. This review will describe currently available non-invasive modalities, along with current evidence-based guidelines and appropriate use criteria in the assessment of low- and intermediate-risk patients with suspected, stable CAD. PMID- 27717540 TI - Notch sensitivity jeopardizes titanium locking plate fatigue strength. AB - INTRODUCTION: Notch sensitivity may compromise titanium-alloy plate fatigue strength. However, no studies providing head-to-head comparisons of stainless steel or titanium-alloy locking plates exist. MATERIALS AND METHODS: Custom designed identically structured locking plates were made from stainless steel (F138 and F1314) or titanium alloy. Three screw-hole designs were compared: threaded screw-holes with angle edges (type I); threaded screw-holes with chamfered edges (type II); and non-threaded screw-holes with chamfered edges (type III). The plates' bending stiffness, bending strength, and fatigue life, were investigated. The stress concentration at the screw threads was assessed using finite element analyses (FEA). RESULTS: The titanium plates had higher bending strength than the F1314 and F138 plates (2.95:1.56:1) in static loading tests. For all metals, the type-III plate fatigue life was highest, followed by type-II and type-I. The type-III titanium plates had longer fatigue lives than their F138 counterparts, but the type-I and type-II titanium plates had significantly shorter fatigue lives. All F1314 plate types had longer fatigue lives than the type-III titanium plates. The FEA showed minimal stress difference (0.4%) between types II and III, but the stress for types II and III was lower (11.9% and 12.4%) than that for type I. CONCLUSIONS: The screw threads did not cause stress concentration in the locking plates in FEA, but may have jeopardized the fatigue strength, especially in the notch-sensitive titanium plates. Improvement to the locking plate design is necessary. PMID- 27717541 TI - The efficacy of a novel saline/bipolar radiofrequency energy instrument for arresting ongoing solid and non-solid organ hemorrhage in a swine model. AB - INTRODUCTION: Ongoing hemorrhage is often life threatening and can be challenging to stop in critically injured patients. Traditional techniques for addressing this issue include high voltage cautery (Bovie), topical hemostatic application, and the delivery of ignited argon gas. The goal of this study was to evaluate the efficacy of a novel energy device for arresting ongoing bleeding from both solid and non-solid organs within a swine model. METHODS: A novel instrument utilizing bipolar radiofrequency (RF) energy which acts to ignite/boil dripping saline from a small hand piece was employed to arrest ongoing hemorrhage from an escalating series of injuries in large male swine. Liver, spleen, kidney, lung, heart, inferior vena cava and abdominal wall targets were evaluated and digitally recorded. Methodology was descriptive. RESULTS: Four large male swine received escalating injuries to their liver, spleen, kidney, lung, heart, inferior vena cava and abdominal wall. Injury patterns included a variety of surface decapsulation, superficial lacerations, deep lacerations, "through and through" missiles and complete transections. Application of the bipolar/RF instrument to sites of ongoing hemorrhage was successful in 97% of all scenarios. Depth of tissue penetration via microscopic evaluation ranged from 1.1mm to 3.0mm depending on the target organ composition. No air leaks were observed following application to the bleeding lung. Surgeon reported 'ease of use' score was high (4.8/5). CONCLUSION: This energy technology is successful in arresting ongoing hemorrhage from varying intensities of traumatic injuries to the liver, spleen, kidney, abdominal wall, lung and heart in the swine model. Additional testing is required before advocating its use on any thoracic organs. PMID- 27717542 TI - Is radiograph glenopolar angle accurate for extraarticular scapular neck fractures? AB - BACKGROUND: Plain radiographs still play a role in management of extraarticular scapular neck fractures. Glenopolar angle (GPA) is one of the radiograph measurements that is used to determine the necessity for surgery. Our aim was to establish reliability of GPA on plain radiograph in patients with extraarticular scapular neck fractures. METHODS: We performed a multicentre retrospective study including all patients with extraarticular scapular neck fractures with available imaging between 2006 and 2012. We excluded intra-articular glenoid fractures, scapular blade fractures, acromion fractures, and scapular spine fractures. We compared GPA on plain radiograph with three dimensional computed tomography (3D CT) measurement, as well as contribution of radiograph rotational error, glenoid inclination, and medial shortening of glenoid fragment towards GPA measurement. RESULTS: One hundred patients met the inclusion criteria. The mean difference between the GPA measurements on radiographs and 3D CT was 6.1+/-0.85 degrees (95% confidence interval) as an absolute value. In terms of contribution to GPA values, GPA changed by one degree with ten degrees of radiograph rotational error, three degrees of glenoid inclination, and three millimetres of glenoid fragment medial shortening. CONCLUSION: Plain radiograph can provide a clinician with a reasonable estimation of the GPA. Glenoid inclination has a greater influence on GPA compared to medial shortening. PMID- 27717543 TI - [Obsessive-compulsive disorder as seen by those who are confronted with it: A survey of patients, relatives and clinicians]. AB - INTRODUCTION: Obsessive compulsive disorder (OCD) is one of the most disabling mental health disorders due to its negative impact on the patient's quality of life as well on that of her living caregivers. This disorder generates an additional burden for relatives, which may in turn affect the family dynamics and impair the evolution of the disease. Along with medications, cognitive behavioral therapy (CBT) represents a well-validated first line of treatment for OCD. However, therapeutic responses across patients are uneven with often residual symptoms and limited quality of life improvements. In total, OCD is a severely debilitating disease with repercussions on both personal, social and professional lives of patients and their relatives even after clinically-delivered treatments. The mutual identification of points of convergence and divergence in social representations is a factor that contributes to satisfactory interpersonal relationships. In the care relationship in general and particularly in the field of mental health, taking account of these different representations and expectations is essential for improving the care process: upstream of the care in the choice the therapeutic strategy and in strengthening the therapeutic alliance. Although less studied, the relationship with relatives of patients also depends on representations of each which have a significant impact on clinical outcomes and experience of the disease. OBJECTIVE: To carry out the first study of cross-representations of OCD in three groups of people affected by it: those who suffer, their families and clinicians. HYPOTHESIS: Considering the experiences and knowledge of patients, relatives and clinicians, we assumed that their representations related to OCD would partially overlap. Specifically, we assumed that the positioning of each population compared to the other two would differ depending on the investigated dimensions: nosology, etiology, therapy and psychiatric disability. METHODS: From 2010 to 2011 we conducted an online survey among self-declared OCD-patients (n=86), OCD-patients' relatives (n=38) and clinicians (n=79). The questionnaire included both closed questions regarding the nosology, etiology, therapy and psychiatric disabilities and open questions probing the representations of the disorder and its evolution, its impact on personal, social and professional domains, and on the quality of life. In particular, we investigated how each population conceived the role and involvement of the relatives in the care process and how they dealt daily with the disorder. RESULTS: Confirming our hypothesis, our results showed that representations of OCD converge on the DSM-based definition of the disorder conveyed by patient associations and mass media. The three populations also recognize the burden and the handicap associated with OCD considerably restrict their daily functioning. However, patients and relatives differ from clinicians in their view of the etiology and their expectations of the therapeutic process. Unexpectedly, patients do not report frequent stigmatization although this may reflect their attempt to hide their disorder as a form of self-stigmatization. Patients focus on care modalities (alternative therapies) motivated by quality of life improvement rather than symptom reduction put forward by clinicians. Relatives ask for being involved in the care process. CONCLUSION: Our study emphasizes the importance for health professionals to take into account the expectations of patients and their relatives in order to maximize the therapeutic alliance and efficiency of treatment. PMID- 27717544 TI - Targeting prostate cancer with compounds possessing dual activity as androgen receptor antagonists and HDAC6 inhibitors. AB - While enzalutamide and abiraterone are approved for treatment of metastatic castration-resistant prostate cancer (mCRPC), approximately 20-40% of patients have no response to these agents. It has been stipulated that the lack of response and the development of secondary resistance to these drugs may be due to the presence of AR splice variants. HDAC6 has a role in regulating the androgen receptor (AR) by modulating heat shock protein 90 (Hsp90) acetylation, which controls the nuclear localization and activation of the AR in androgen-dependent and independent scenarios. With dual-acting AR-HDAC6 inhibitors it should be possible to target patients who don't respond to enzalutamide. Herein, we describe the design, synthesis and biological evaluation of dual-acting compounds which target AR and are also specific towards HDAC6. Our efforts led to compound 10 which was found to have potent dual activity (HDAC6 IC50=0.0356MUM and AR binding IC50=<0.03MUM). Compound 10 was further evaluated for antagonist and other cell-based activities, in vitro stability and pharmacokinetics. PMID- 27717545 TI - Six new compounds from Atractylodes lancea and their hepatoprotective activities. AB - Two new phenolic glycosides with a rare beta-d-glucopyranosyl-(1->3)-alpha-l rhamnopyranosyl moiety (1, 2), one new dihydrobenzofuran derivative (3), one new pyrazine derivative (4), two new furofuran lignan glycosides (5, 6), and six known compounds (7-12) were isolated from the rhizomes of Atractylodes lancea. The structures of these compounds were elucidated by extensive spectroscopic analyses combined with the experimental and calculated electronic circular dichroism and the Rh2(OCOCF3)4-induced circular dichroism for configurational assignments.

PMID- 27717547 TI - Femur, tibia and fibula bone templates to estimate subject-specific knee ligament attachment site locations. AB - In-vivo estimates of the positions of knee ligament attachment sites are crucial for subject-specific knee modelling. The present study provides template digital models of femur, tibia and fibula that embed the positions of centroids of the origins and insertions of cruciate and collateral ligaments, along with information on their dispersion related to inter-individual variability. By using a shape transformation procedure of choice, these templates can be made to match anatomical information measured on a subject under analysis. Generic bone digital models of the femur, tibia and fibula were first chosen as bone templates. Ligament attachment areas were accurately identified through dissection on the bones of 11 knee specimens, and marked using radio opaque paint. Digital models of these bones embedding the positions of the centroids of the identified ligament attachment areas were thereafter obtained using medical imaging techniques. These centroids were mapped onto the relevant bone template, thus obtaining a cloud of 11 points for each attachment site, and descriptive statistics of the position of these points were thereafter determined. Dispersion of these positions, essentially due to inter-individual variability, was below 6mm for all attachment areas. The accuracy with which subject-specific ligament attachment site positions may be estimated using the bone template models provided in this paper was also assessed using the above-mentioned 11 specimens data set, and a leave-one-out cross validation approach. Average accuracy was found to be 3.3+/-1.5mm and 5.8+/-2.9mm for femoral and tibial/fibular attachment sites, respectively. PMID- 27717546 TI - Age and sex alone are insufficient to predict human rib structural response to dynamic A-P loading. AB - Thoracic injuries from motor vehicle crashes (MVCs) are common in children and the elderly and are associated with a high rate of mortality for both groups. Rib fractures, in particular, are linked to high mortality rates which increase with the number of fractures sustained. Anthropomorphic test devices (ATDs) and computational models have been developed to improve vehicle safety, however these tools are constructed based on limited physical datasets. To-date, no study has explored variation of rib structural properties across the entire age spectrum with data obtained using the same experimental methodology to allow for comparison. One-hundred eighty-four ribs from 93 post mortem human subjects (PMHS) (70 male, 23 female; ages 4-99) were subjected to dynamic bending tests simulating a frontal impact to the thorax. Structural mechanical properties were calculated and a multi-level statistical model quantified the sample variance as explained by age and sex. Displacement (deltaX), peak force (Fpeak), linear structural stiffness (K), energy absorption to fracture (Utot), and plastic properties including post-yield energy absorption (UPl), plastic displacement (deltaPl), and the ratio of elastic to secant stiffness (K-ratio) all showed negative relationships with age, while only Fpeak, K, and Utot were dependent on sex. Despite these relationships being statistically significant, only 7-39% of variance is explained by age and only 3-17% of variance is explained by sex. This demonstrates that variability in bone properties is more complex than simply chronological age- and sex-dependence and should be explored in the context of biological mechanisms instead. PMID- 27717548 TI - An evolutionary model of osteoarthritis including articular cartilage damage, and bone remodeling in a computational study. AB - With osteoarthritis, a complex set of progressive chemical, biological, and mechanical changes occur in both cartilage and bone. The aim of this study is to develop a high-fidelity computational model of the complete bone-cartilage unit to study the evolution of osterarthritis-induced articular cartilage (AC) damage and remodeling of subchondral cortical bone (SCB) and subchondral trabecular bone (STB). A finite element model of spherical indentation was developed with a depth dependent anisotropic model of degenerating articular cartilage, a calcified cartilage (CC) zone, and SCB and STB remodeling regions. Calcified tissue (CC, SCB, and STB) and AC material regions were integrated to form an evolutionary bone-cartilage unit model. Results indicate that with indentation loading, articular cartilage damage occurs at the articular surface. Furthermore, bone remodeling was predicted to occur with a net stiffening of the subchondral bone plate. Changes in indentation force were minimal (<2%) between initial and final peak indentation loading. However, additional degradation and wear of AC and/or alterations in loading may have more pronounced effects on the mechanical response of the bone-cartilage unit. Bone remodeling and articular cartilage damage predictions are consistent with experimental observations that cartilage damage begins at the articular surface and subchondral bone experiences a thickening (i.e., stiffening) response with osteoarthritis. Our results provide insight into the early-term initiation behavior of osteoarthritis; the potential consequences of evolutions in AC, SCB, and STB with disease progression; and may guide future experimental and computational studies to elucidate mechanisms of osteoarthritis progression. PMID- 27717549 TI - Hemodynamic modeling of leukocyte and erythrocyte transport and interactions in intracranial aneurysms by a multiphase approach. AB - Hemodynamics has been recognized as an important factor in the development, growth, and rupture of cerebral aneurysms, and investigated by computational fluid dynamics techniques using a single phase approach. However, flow-dependent cell transport and interactions are usually ignored in single phase models, in which blood is usually treated as a single phase Newtonian fluid. For getting better insight into the underlying pathology of intracranial aneurysm, cell transport and interactions should be covered in hemodynamic studies. In the present study, a multiphase hemodynamic model incorporating cell transport and interactions was developed, in which blood was modeled as multiphase fluid having a continuous phase (plasma) and two particulate phases (erythrocytes and leukocytes). The model showed good agreement with experimental data and observations in the literature, and was applied to four patient-specific aneurysms in a pulsatile manner. Leukocyte accumulations were predicted at locations with flow disturbance and low wall shear stress. The concentrations of leukocyte at accumulation sites were found to exceed 200 to 500% of normal physiological level on three unstable aneurysms, including two ruptured aneurysms and a growing aneurysm where accumulation was observed near a daughter sac and a secondary aneurysm. This suggested that aneurysms with complex secondary flow patterns could be prone to leukocyte accumulation on the wall. As this is the first study to characterize cell transport and interactions in aneurysm hemodynamics, our model can serve as a foundation for future intracranial aneurysm models.

AB - OBJECTIVE: To investigate the effects of brain-derived neurotrophic factor (BDNF) supplementation to freezing and thawing media on frozen-thawed human sperm parameters. DESIGN: Laboratory study. SETTING: University hospital. PATIENT(S): Semen samples from 21 healthy fertile men. INTERVENTION(S): We measured reactive oxygen species (ROS) by flow cytometry using the probes dichlorofluorescin diacetate for intracellular hydrogen peroxide (H2O2) and dihydroethidium for intracellular superoxide anion (O2-*), sperm plasma membrane integrity by flow cytometry, caspase-3 activity using ELISA, and AKT phosphorylation status using Western blot in sperm that was cryopreserved and thawed in media either supplemented with BDNF or without BDNF supplementation (control). MAIN OUTCOME MEASURE(S): Sperm motility, viability, ROS levels, caspase-3 activity and AKT phosphorylation. RESULT(S): The percentage of motile and viable sperm cells was significantly higher in BDNF-supplemented groups as compared with the nonsupplemented (control) group. There was a significant difference in AKT phosphorylation status between BDNF-supplemented groups and the control group. Moreover, the levels of intracellular H2O2 and caspase-3 activity were significantly lower in the sperm cells that were frozen and thawed in media supplemented with BDNF compared with in the control group. CONCLUSION(S): BDNF supplementation to sperm freezing or thawing media has protective effects against oxidative stress and apoptosis in frozen-thawed human spermatozoa and could improve sperm function, probably through the activation of AKT. PMID- 27717553 TI - New developments in long-acting reversible contraception: the promise of intrauterine devices and implants to improve family planning services. AB - After decades of having the developed world's highest rates of unintended pregnancy, the United States finally shows signs of improvement. This progress is likely due in large part to increased use of highly effective long-acting reversible methods of contraception. These methods can be placed and do not require any maintenance to provide years of contraception as effective as sterilization. Upon removal, fertility returns to baseline rates. This article addresses advances in both software-improved use and elimination of barriers to provide these methods; and hardware-novel delivery systems and devices. PMID- 27717552 TI - Evaluation of an ultra-low-dose oral contraceptive for dysmenorrhea: a placebo controlled, double-blind, randomized trial. AB - OBJECTIVE: To evaluate the efficacy and safety of an ultra-low-dose oral contraceptive (NPC-01; 0.02 mg ethinyl estradiol and 1 mg norethisterone) in subjects with dysmenorrhea. DESIGN: Placebo-controlled, double-blind, randomized trial. SETTING: Clinical trial sites. PATIENT(S): Two hundred fifteen subjects with dysmenorrhea. INTERVENTION(S): Subjects were randomly assigned to receive NPC-01, placebo, or IKH-01 (0.035 mg ethinyl estradiol and 1 mg norethisterone) for four cycles. MAIN OUTCOME MEASURE(S): Total dysmenorrhea score (verbal rating scale) assessing pain on the basis of limited ability to work and need for analgesics. RESULT(S): The reductions of total dysmenorrhea score and visual analog scale score after the treatment were significantly higher in the NPC-01 group than in the placebo group. Furthermore, the efficacy of NPC-01 was comparable to that of IKH-01. The overall incidence of side effects was significantly higher in the NPC-01 group than in the placebo group. All side effects that occurred in the NPC-01 group were previously reported in patients receiving IKH-01. No serious side effects occurred. CONCLUSION(S): The ultra-low dose contraceptive NPC-01 relieved dysmenorrhea as effectively as IKH-01. Thus, NPC-01 could represent a new option for long-term treatment of dysmenorrhea. CLINICAL TRIAL IDENTIFICATION NUMBER: NCT01129102. PMID- 27717554 TI - Effect of first line cancer treatment on the ovarian reserve and follicular density in girls under the age of 18 years. AB - OBJECTIVE: To study the impact of first-line antineoplastic treatment on ovarian reserve in young girls returning for ovarian tissue cryopreservation (OTC) in connection with a relapse. DESIGN: Retrospective case-control study. SETTING: University hospitals. PATIENT(S): Sixty-three girls under the age of 18 years who underwent OTC before (group 1: 31 patients) and after (group 2: 32 patients) their initial cancer treatment. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Follicular densities (follicles/mm3) measured from an ovarian cortical biopsy before OTC. The ovarian volume (mL) of entire ovaries excised for OTC was also monitored. RESULT(S): There was no statistically significant difference in the mean age or follicular density between groups 1 and 2 (334 +/- 476/mm3 vs. 327 +/ 756/mm3). In contrast, the ovarian volume and total number of ovarian cortex chips cryopreserved were statistically significantly lower in patients who received gonadotoxic treatment before OTC (mean +/- standard deviation [SD]: ovarian volume, 5.3 +/- 3.1 mL vs. 2.9 +/- 2.1 mL, respectively; number of cortex chips: 21.3 +/- 8.1 vs. 15.2 +/- 7.1, respectively). The reduction in the estimated ovarian reserve ranged from 10% to 20% in children to around 30% in adolescent girls (>10 years). CONCLUSION(S): Girls under the age of 10 tolerate a gonadotoxic insult better than adolescents, who may experience up to a 30% reduction in the ovarian reserve via first-line gonadotoxic treatment, which at present is considered to have little effect on the follicle pool. This information will improve counseling of young female cancer patients in deciding whether to undergo fertility preservation treatment. PMID- 27717556 TI - Erratum. PMID- 27717555 TI - Establishing reference values for age-related spermatogonial quantity in prepubertal human testes: a systematic review and meta-analysis. AB - OBJECTIVE: To collect published data on spermatogonial quantity in the testes of healthy children and calculate the reference values of spermatogonial quantities throughout prepuberty. DESIGN: Systematic literature search in PubMed and EMBASE focusing on the number of spermatogonia per transverse tubular cross section (S/T) and spermatogonial density per cubic centimeter (cm3) of testicular volume (S/V) throughout prepuberty. SETTING: None. PATIENT(S): None. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Polynomial meta-regression analyses of S/T and S/V of healthy boys from the ages of 0 to 14 years. RESULT(S): We found six papers describing original quantitative data on S/T and S/V of healthy boys (total n = 334 and 62, respectively) that were suitable for meta-analysis. Polynomial meta regression analyses of S/T and S/V demonstrated a clear pattern of spermatogonial quantity throughout prepubertal life. This consisted of a decline during the first 3 years of life, a gradual increase until the ages of 6 to 7 years, a plateau until the age of 11 years, and a sharp incline reaching pubertal numbers at 13 to 14 years of age. The association between S/T and S/V allowed us to perform S/T to S/V extrapolation, creating reference S/V (rS/V) values throughout prepubertal life from a cohort of 372 boys. CONCLUSION(S): Spermatogonial quantity varies during testicular development toward puberty. The values found in this study may serve as a baseline clinical reference to study the impact of diseases and adverse effects of gonadotoxic treatments on spermatogonial quantity in prepubertal testes. Spermatogonial quantity reference values may also help to evaluate the quality of testicular biopsy samples acquired for fertility preservation of prepubertal boys. PMID- 27717557 TI - Expression of katanin p80 in human spermatogenesis. AB - OBJECTIVE: To define the stage-by-stage expression of KATNB1 during human spermatogenesis. DESIGN: Gene expression analysis, histologic and immunohistochemical evaluation. SETTING: University research laboratories and andrological clinic. PATIENT(S): Eighty human testicular biopsy samples: 43 showing normal spermatogenesis, 9 with maturation arrest at level of spermatocytes, 8 with maturation arrest at level of spermatogonia, and 20 with a Sertoli cell only syndrome. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Evaluation of katanin p80 expression in normal as well as impaired spermatogenesis on mRNA (RT-PCR, RT-qPCR, and in situ hybridization) and protein level (immunohistochemistry/immunofluorescence). RESULT(S): KATNB1 messenger RNA is exclusively expressed in germ cells, and quantitatively reduced in maturation arrests at the level of spermatogonia. The KATNB1 protein was detected in type B spermatogonia entering meiosis and in the Golgi complex of pachytene spermatocytes. Immediately before the first meiotic division, it is colocalized with the cleaving centriole. It was also detected in early round spermatids in the dictyosome. CONCLUSION(S): The expression and localization of KATNB1 support a role in spindle formation. The localization of KATNB1 in early round spermatids suggests an involvement in the formation of microtubule-based structures during spermiogenesis (manchette and flagellum). These data are consistent with the demonstrated role of KATNB1 in mouse meiosis, nuclear shaping, and flagellum formation of sperm and suggest the strong conservation of function even between distantly related species. PMID- 27717560 TI - Biofouling and control approaches in membrane bioreactors. AB - Membrane fouling (especially biofouling) as a critical issue during membrane reactor (MBR) operation has attracted much attention in recent years. Although previous review papers have presented different aspects of MBR's fouling when treating various wastewaters, the information related to biofouling in MBRs has only simply or partially reviewed. This work attempts to give a more comprehensive and elaborate explanation of biofilm formation, biofouling factors and control approaches by addressing current achievements. This also suggests to a better way in controlling biofouling by developing new integrated MBR systems, novel flocculants and biomass carriers. PMID- 27717559 TI - Peritoneum and omentum are natural reservoirs for chondrocytes of osteochondral autografts: A comparative animal study. AB - OBJECTIVE: The purpose of this study was to investigate the effects of the omentum, peritoneum, paratenon and skeletal muscle on the proliferation of the cartilage tissue using rabbit model as an in vivo culture medium. METHODS: 6 months old forty-five New Zealand rabbits were randomized into omentum, peritoneum, muscle, and Achilles paratenon groups. Standard sized osteochondral grafts were harvested from right knees and immediately placed into the specified tissues. Control group was fresh cartilage at the end of follow-up. After five months, samples were collected and evaluated macroscopically by measuring their dimensions (vertical = D1, horizontal = D2, and depth = D3) and volumes, and histologically by counting the chondrocyte number using camera lucida method. RESULTS: Macroscopically, increase in mean values for D1 and D2 dimensions of specimens from paratenon and omentum compared to pretransplant dimensions was statistically significant (p < 0.05). Although, volume measurements were higher in omentum and peritoneum group compared to pretransplant dimensions, increase was not significant (p > 0.05). Histologically, mean chondrocyte count was 14.0 +/- 0.6 in fresh articular cartilage. Mean chondrocyte counts were 14.4 +/- 0.9 in omentum group, 15.4 +/- 1.0 in peritoneum group, 9.7 +/- 1.3 in muscle group and 9.2 +/- 0.4 in Achilles paratenon group respectively. However, mean chondrocyte counts were higher in samples of omentum and peritoneum group compared to fresh articular cartilage, increase was not statistically significant (p > 0.05). DISCUSSION: Transplantation of the cartilage grafts into mesothelium enhanced the chondrocyte counts and volumes compared with the pretransplant measurements. Mesothelium may have the potential to be used as an in vivo culture medium for osteochondral tissue growth. PMID- 27717562 TI - Opioids and overdoses: Time to get serious; time to get sensible. PMID- 27717561 TI - Microbial community structure of different electrode materials in constructed wetland incorporating microbial fuel cell. AB - The microbial fuel cell coupled with constructed wetland (CW-MFC) microcosms were operated under fed-batch mode for evaluating the effect of electrode materials on bioelectricity generation and microbial community composition. Experimental results indicated that the bioenergy output in CW-MFC increased with the substrate concentration; maximum average voltage (177mV) was observed in CW-MFC with carbon fiber felt (CFF). In addition, the four different materials resulted in the formation of significantly different microbial community distribution around the anode electrode. The relative abundance of Proteobacteria in CFF and foamed nickel (FN) was significantly higher than that in stainless steel mesh (SSM) and graphite rod (GR) samples. Notably, the findings indicate that CW-MFC utilizing FN anode electrode could apparently improve relative abundance of Dechloromonas, which has been regarded as a denitrifying and phosphate accumulating microorganism. PMID- 27717563 TI - Management of recurrent aphthous ulcers using low-level lasers: A systematic review. AB - BACKGROUND AND OBJECTIVE: The exact etiology of recurrent aphthous ulcers (RAS) is unknown. The management of RAS is not always straightforward. The aim of this review is to critically analyze and summarize the clinical literature focusing on the management of aphthous ulcers using low-level lasers. MATERIALS AND METHODS: The Medline (PubMed), Web of Knowledge (ISI), Cochrane Central Register of Controlled Trials (CENTRAL) and Embase databases were searched electronically for studies published in last 20 years (1995-2015) using the keywords "recurrent aphthous stomatitis," "aphthous ulcers," and "laser." RESULTS: A total of 85 articles were found during the initial search; 76 studies were excluded for not fulfilling the criteria whereas nine studies were deemed suitable for this review. Among the included studies, two articles were case reports and seven were randomized clinical trials. Study design, sample size, type of intervention and control of each study were critically analyzed and summarized according to the CONSORT protocol. In majority of the patients, immediate pain relief and accelerated ulcer healing was observed following irradiation with lasers. CONCLUSIONS: Although various types of lasers have succeeded in providing immediate pain relief to patients, carbon dioxide (CO2) lasers have the unique advantage of requiring a short exposure time (5-10s). In order to ascertain the efficacy of laser for treating ulcers in the clinical setting, more clinical trials are required. PMID- 27717558 TI - Proton pump inhibitors decrease eotaxin-3/CCL26 expression in patients with chronic rhinosinusitis with nasal polyps: Possible role of the nongastric H,K ATPase. AB - BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is often characterized by tissue eosinophilia that is associated with poor prognosis. Recent findings that proton pump inhibitors (PPIs) directly modulate the expression of eotaxin-3, an eosinophil chemoattractant, in patients with eosinophilic diseases suggest therapeutic potential for PPIs in those with CRSwNP. OBJECTIVE: We assessed the effect of type 2 mediators, particularly IL-13 and eotaxin-3, on tissue eosinophilia and disease severity in patients with chronic rhinosinusitis (CRS). Further investigation focused on PPI suppression of eotaxin-3 expression in vivo and in vitro, with exploration of underlying mechanisms. METHODS: Type 2 mediator levels in nasal tissues and secretions were measured by using a multiplex immunoassay. Eotaxin-3 and other chemokines expressed in IL-13-stimulated human sinonasal epithelial cells (HNECs) and BEAS 2B cells with or without PPIs were assessed by using ELISA, Western blotting, real-time PCR, and intracellular pH imaging. RESULTS: Nasal tissues and secretions from patients with CRSwNP had increased IL-13, eotaxin-2, and eotaxin 3 levels, and these were positively correlated with tissue eosinophil cationic protein levels and radiographic scores in patients with CRS (P < .05). IL-13 stimulation of HNECs and BEAS-2B cells dominantly induced eotaxin-3 expression, which was significantly inhibited by PPIs (P < .05). Patients with CRS taking PPIs also showed lower in vivo eotaxin-3 levels compared with those without PPIs (P < .05). Using intracellular pH imaging and altering extracellular K+, we found that IL-13 enhanced H+,K+-exchange, which was blocked by PPIs and the mechanistically unrelated H,K-ATPase inhibitor, SCH-28080. Furthermore, knockdown of ATP12A (gene for the nongastric H,K-ATPase) significantly attenuated IL-13 induced eotaxin-3 expression in HNECs. PPIs also had effects on accelerating IL 13-induced eotaxin-3 mRNA decay. CONCLUSION: Our results demonstrated that PPIs reduce IL-13-induced eotaxin-3 expression by airway epithelial cells. Furthermore, mechanistic studies suggest that the nongastric H,K-ATPase is necessary for IL-13-mediated epithelial responses, and its inhibitors, including PPIs, might be of therapeutic value in patients with CRSwNP by reducing epithelial production of eotaxin-3. PMID- 27717565 TI - Patient safety improvement interventions in children's surgery: A systematic review. AB - BACKGROUND: Adult surgical patient safety literature is plentiful; however, there is a disproportionate paucity of published safety work in the children's surgical literature. We sought to systematically evaluate the nature and quality of patient safety evidence pertaining to pediatric surgical practice. METHODS: Systematic search of MEDLINE and EMBASE databases and gray literature identified 1399 articles. Data pertaining to demographics, methodology, interventions, and outcomes were extracted. Study quality was assessed utilizing formal criteria. RESULTS: 20 studies were included. 14 (70%) comprised peer-reviewed articles. 18 (90%) were published in the last 4years. 13 (65%) described a novel intervention, and 7 (35%) described a modification of an existing intervention. Median patient sample size was 79 (29-1210). A large number (n=55) and variety (n=35) of measures were employed to evaluate the effect of interventions on patient safety. 15 (75%) studies utilized a checklist tool as a component of their intervention. 9 (45%) studies [comprising handoff tools (n=7); checklists (n=1); and multidimensional quality improvement initiatives (n=1)] reported a positive effect on patient safety. Quality assessment was undertaken on 14 studies. Quantitative studies had significantly higher quality scores than qualitative studies (61 [0-89] vs 44 [11-78], p=0.03). CONCLUSIONS: Pediatric surgical patient safety evidence is in its early stages. Successful interventions that we identified were typically handoff tools. There now ought to be an onus on pediatric surgeons to develop and apply bespoke pediatric surgical safety interventions and generate an evidence base to parallel the adult literature. LEVEL OF EVIDENCE: Level IV, Case series with no comparison group. PMID- 27717564 TI - Prospective validation of the shock index pediatric-adjusted (SIPA) in blunt liver and spleen trauma: An ATOMAC+ study. AB - BACKGROUND: Age-adjusted pediatric shock index (SIPA) does not require knowledge of age-adjusted blood pressure norms, yet correlates with mortality, serious injury, and need for transfusion in trauma. No prospective studies support its validity. METHODS: A multicenter prospective observational study of patients 4 16years presenting April 2013-January 2016 with blunt liver and/or spleen injury (BLSI). SIPA (maximum heart rate/minimum systolic blood pressure) thresholds of >1.22, >1.0, and >0.9 in the emergency department were used for 4-6, 7-12 and 13 16year-olds, respectively. Patients with ISS <=15 were excluded to conform to the original paper. Discrimination outcomes were compared between SIPA and shock index (SI). RESULTS: Of 1008 patients, 386 met inclusion. SI was elevated in 321, and SIPA elevated in 282. The percentage of patients with elevated index (SI or SIPA) and blood transfusion within 24 hours (30% vs 34%), BLSI grade >=3 requiring transfusion (28% vs 32%), operative intervention (14% vs 16%) and ICU admission (64% vs 67%) was higher in the SIPA group. CONCLUSION: SIPA was validated in this multi-institutional prospective study and identified a higher percentage of children requiring additional resources than SI in BLSI patients. SIPA may be useful for determining necessary resources for injured patients with BLSI. LEVEL OF EVIDENCE: Level II prognosis. PMID- 27717567 TI - A new-generation 3D ozone FACE (Free Air Controlled Exposure). AB - To artificially simulate the impacts of ground-level ozone (O3) on vegetation, ozone FACE (Free Air Controlled Exposure) systems are increasingly recommended. We describe here a new-generation, three-dimensional ozone FACE, with O3 diffusion through laser-generated micro-holes, pre-mixing of air and O3, O3 generator with integral oxygen generator, continuous (day/night) exposure and full replication. Based on three O3 levels and assumptions on the pre-industrial O3 levels, we describe principles to calculate relative yield/biomass and estimate impacts even at lower-than-ambient O3 levels. The case study is called FO3X, and is at present the only ozone FACE in Mediterranean climate and one of the very few ozone FACEs investigating more than one stressor at a time. The results presented here will give further impulse to the research on O3 impacts on vegetation all over the world. PMID- 27717566 TI - Retroperitoneoscopic assisted single-site pyeloplasty using EZ access in children: Comparison with open dismembered pyeloplasty. AB - PURPOSE: The aim of this study was to compare the results of the retroperitoneoscopic assisted pyeloplasty (RASP) using EZ access (silicone rubber cap) with open dismembered pyeloplasty (ODP) in children. METHODS: A retrospective review was performed of patients treated for ureteropelvic junction (UPJ) obstruction with either RASP or ODP from 2010 to 2015. For patients with RASP, two 5-mm trocars were placed in the EZ access. The UPJ was dissected retroperitoneoscopically and dismembered pyeloplasty was performed extracorporeally. Patient demographics and operative outcomes were compared between the groups. RESULTS: A total of 50 children were included, with 25 RASP and 25 ODP. Mean patient age was 49months in the RASP group and 53months in the ODP group. Perioperative outcomes, including operative time (185 vs 188min) and postoperative hospital stay (2.0 vs 2.2days), were similar between the two groups. Mean skin scar length (17 vs 34mm) was significantly smaller in the RASP group. The postoperative success rate (96% vs 100%) was not significantly different between the groups. CONCLUSIONS: The RASP represents a safe and effective single-site procedure in children. This procedure significantly reduces the skin scar length and has equivalent surgical outcomes to ODP. THE TYPE OF STUDY: Retrospective comparative study. LEVELS OF EVIDENCE: III. PMID- 27717568 TI - Hexadecane degradation of Pseudomonas aeruginosa NY3 promoted by glutaric acid. AB - For further understanding of the roles of small organic acids commonly produced during alkane degradation, glutaric acid was found to be effective for promoting hexadecane degradation by P. aeruginosa NY3. Our results demonstrated that the synchronous metabolism of glutaric acid could increase both the growth rates and hexadecane degradation ability of P. aeruginosa NY3. Glutaric acid was proved to be able to increase the ratios of the concentrations of NAD+ and NADH inside strain NY3 cells, and subsequently accelerated cell growth rates through improving electron respiration rates. All the results of the activities of hexadecane monooxygenase, the expression levels of alkB1 and alkB2 gens and the bioconversion rate of hexadecane to 1-hexadecanol were confirmed that coexistence of glutaric acid could greatly increase the reaction rate of the first step of enzymeticlly degradation of hexadecane into hexadecanol. This also explained the promotion mechanism of glutaric acid on hexadecane degradation by P. aeruginosa strain from a certain point of view for the first time. PMID- 27717569 TI - Phyto-rhizoremediation of polychlorinated biphenyl contaminated soils: An outlook on plant-microbe beneficial interactions. AB - Polychlorinated biphenyls (PCBs) are toxic chemicals, recalcitrant to degradation, bioaccumulative and persistent in the environment, causing adverse effects on ecosystems and human health. For this reason, the remediation of PCB contaminated soils is a primary issue to be addressed. Phytoremediation represents a promising tool for in situ soil remediation, since the available physico-chemical technologies have strong environmental and economic impacts. Plants can extract and metabolize several xenobiotics present in the soil, but their ability to uptake and mineralize PCBs is limited due to the recalcitrance and low bioavailability of these molecules that in turn impedes an efficient remediation of PCB-contaminated soils. Besides plant degradation ability, rhizoremediation takes into account the capability of soil microbes to uptake, attack and degrade pollutants, so it can be seen as the most suitable strategy to clean-up PCB-contaminated soils. Microbes are in fact the key players of PCB degradation, performed under both aerobic and anaerobic conditions. In the rhizosphere, microbes and plants positively interact. Microorganisms can promote plant growth under stressed conditions typical of polluted soils. Moreover, in this specific niche, root exudates play a pivotal role by promoting the biphenyl catabolic pathway, responsible for microbial oxidative PCB metabolism, and by improving the overall PCB degradation performance. Besides rhizospheric microbial community, also the endophytic bacteria are involved in pollutant degradation and represent a reservoir of microbial resources to be exploited for bioremediation purposes. Here, focusing on plant-microbe beneficial interactions, we propose a review of the available results on PCB removal from soil obtained combining different plant and microbial species, mainly under simplified conditions like greenhouse experiments. Furthermore, we discuss the potentiality of "omics" approaches to identify PCB-degrading microbes, an aspect of paramount importance to design rhizoremediation strategies working efficiently under different environmental conditions, pointing out the urgency to expand research investigations to field scale. PMID- 27717570 TI - A hybrid monitoring and modelling approach to assess the contribution of sources of glyphosate and AMPA in large river catchments. AB - Large river catchments with mixed land use capture pesticides from many sources, and degradable pesticides are converted during downstream transport. Unravelling the contribution of pesticide source and the effect of degradation processes is a challenge in such areas. However, insight and understanding of the sources is important for targeted management, especially when water is abstracted from the river for drinking water production. The river Meuse is such a case. A long-term monitoring data set was applied in a modelling approach for assessing the contribution of waste water treatment plants (WWTPs) and tributaries (sub-basins) to surface water contamination, and to evaluate the effect of decay on the downstream concentrations of glyphosate and AMPA at the point of drinking water abstraction. The results show that WWTPs are important contributors for glyphosate and AMPA in large river catchments with mixed land uses. In the studied area, the river Meuse in the Netherlands, the relative contribution of WWTP effluents is above 29% for glyphosate and around 12% for AMPA. Local industries are found to be potentially big contributors of AMPA. Glyphosate entering the river system is gradually converted to AMPA and other degradation productions, which results in downstream loads that are considerably lower than the sum of all influxes. In summer when the travel time is longer due to lower discharge, the first order decay of glyphosate in the river Meuse is estimated to result in about 50% reduction of the downstream glyphosate concentrations over a river stretch of 250km. The contribution of glyphosate decay to the observed AMPA concentrations ranges between 2% and 10%. Contributions are sensitive to seasonal variations in discharge that influence the concentrations through dilution and degradation.

AB - Automated detection of AF from the electrocardiogram (ECG) still remains a challenge. In this study, we investigated two multivariate-based classification techniques, Random Forests (RF) and k-nearest neighbor (k-nn), for improved automated detection of AF from the ECG. We have compiled a new database from ECG data taken from existing sources. R-R intervals were then analyzed using four previously described R-R irregularity measurements: (1) the coefficient of sample entropy (CoSEn), (2) the coefficient of variance (CV), (3) root mean square of the successive differences (RMSSD), and (4) median absolute deviation (MAD). Using outputs from all four R-R irregularity measurements, RF and k-nn models were trained. RF classification improved AF detection over CoSEn with overall specificity of 80.1% vs. 98.3% and positive predictive value of 51.8% vs. 92.1% with a reduction in sensitivity, 97.6% vs. 92.8%. k-nn also improved specificity and PPV over CoSEn; however, the sensitivity of this approach was considerably reduced (68.0%).

PMID- 27717573 TI - Mercury in the ecosystem of Admiralty Bay, King George Island, Antarctica: Occurrence and trophic distribution. AB - Mercury (Hg) can reach the environment through natural and human-related sources, threatening ecosystems all over the planet due to its well known deleterious effects. Therefore, Antarctic trophic webs, despite being relatively isolated, are not exempt of its influence. To evaluate Hg concentrations in an Antarctic ecosystem, different tissues from 2 species of invertebrates, 2 of fish, 8 of birds, 4 of pinnipeds and at least 5 of vegetation were investigated (n=176). For animals, values ranged from 0.018 to 48.7MUgg-1 dw (whole Antarctic krill and Antarctic Fur Seal liver). They were generally correlated to trophic position (assessed by delta15N and delta13C) but also to cephalopods and myctophids consumption. For vegetation, values ranged from 0.014 to 0.227MUgg-1 dw (Colobanthus quitensis and an unidentified lichen), with lichens presenting significantly higher values than mosses, likely due to year-round exposure and absorption of animal derived organic matter, as hypothesized by literature. PMID- 27717574 TI - Occurrence of plastic debris in the stomach of the invasive crab Eriocheir sinensis. AB - The Chinese mitten crab is known as a pest causing damage to fishing gears and fish. On the other hand, this highly invasive species is considered a delicacy by Asian migrants and therefore commercially fished and sold in many countries. The ingestion of plastic by the Chinese mitten crab Eriocheir sinensis from the Baltic coastal waters (Poland) and the Tagus Estuary (Portugal) was studied based on stomach content analysis. As many as 13% of the 302 analysed males and females (38.07-89.07mm carapace width) from both regions, contained microplastic in the form of strands and balls. Most of them were transparent. Ingested plastic particles were identified as fragments of fishing gears. Contamination with plastic may have a negative impact on this species as well as on higher trophic levels feeding on crabs. PMID- 27717575 TI - Modeling and evaluation of the oil-spill emergency response capability based on linguistic variables. AB - An evaluation of the oil-spill emergency response capability (OS-ERC) currently in place in modern marine management is required to prevent pollution and loss accidents. The objective of this paper is to develop a novel OS-ERC evaluation model, the importance of which stems from the current lack of integrated approaches for interpreting, ranking and assessing OS-ERC performance factors. In the first part of this paper, the factors influencing OS-ERC are analyzed and classified to generate a global evaluation index system. Then, a semantic tree is adopted to illustrate linguistic variables in the evaluation process, followed by the application of a combination of Fuzzy Cognitive Maps (FCM) and the Analytic Hierarchy Process (AHP) to construct and calculate the weight distribution. Finally, considering that the OS-ERC evaluation process is a complex system, a fuzzy comprehensive evaluation (FCE) is employed to calculate the OS-ERC level. The entire evaluation framework obtains the overall level of OS-ERC, and also highlights the potential major issues concerning OS-ERC, as well as expert opinions for improving the feasibility of oil-spill accident prevention and protection. PMID- 27717576 TI - Optimizing CT Pulmonary Angiogram Utilization in a Community Emergency Department: A Pre- and Postintervention Study. AB - PURPOSE: Optimizing the utilization of CT pulmonary angiogram (CTPA) for the diagnosis and workup of acute chest pain can provide an opportunity to reduce unnecessary radiation and health care system expense. METHODS: An attempt to improve CTPA utilization began by measuring overall department and clinician specific utilization. This was bolstered by retrospectively evaluating patient charts for pulmonary embolism scoring criteria and D-dimer utilization so as to better understand gaps in diagnostic workup. The department-wide and individualized metrics were then provided to each emergency department clinician and differences between the pre- and postintervention data were evaluated. RESULTS: The percentage of positive CTPAs did not change significantly at 8.7% and 9.2% in the pre- and postintervention groups, respectively. Similarly, the workup of patients based on retrospective PERC and Wells-score criteria did not significantly improve after the intervention. However, the percentage of CTPAs ordered on low D-dimer patients did decrease significantly post-intervention. Further observational analysis uncovered marked variability in clinician ordering behavior and diagnostic rates. CONCLUSIONS: Overall, such an intervention seems to have a limited, though not insignificant, impact on the workup of suspected pulmonary embolism. Calculating provider-specific utilization metrics allows both the radiologist and clinician to better understand opportunities to improve health care delivery.

PMID- 27717579 TI - IVUS and OCT guided primary percutaneous coronary intervention for spontaneous coronary artery dissection with bioresorbable vascular scaffolds. AB - Spontaneous coronary artery dissection (SCAD) is an uncommon but important cause of acute coronary syndrome. The diagnosis of SCAD by an angiogram alone can be challenging and the increasing use of intracoronary imaging has proven an invaluable diagnostic adjunct in this regard. The appropriate initial management of SCAD has been a matter of significant debate. Owing to frequent spontaneous healing of coronary dissection and a higher risk of complications with percutaneous coronary intervention (PCI) in the setting of SCAD, a default approach of mechanical revascularization is not recommended. However in the presence of vessel occlusion and on-going myocardial infarction PCI is mandated. Bioresorbable vascular scaffolds (BVS) offer potential advantages over the conventional stents in the setting of SCAD. We describe a state-of-the-art approach to the acute treatment of SCAD causing STEMI, utilizing intravascular ultrasound (IVUS), optical coherence tomography (OCT) and BVS and discuss management strategies for the modern era. PMID- 27717580 TI - Transpedal approach for iliac artery stenting: A pilot study. AB - OBJECTIVE: To demonstrate the safety and feasibility of the transpedal approach as an alternate arterial access site for iliac artery intervention. BACKGROUND: The common femoral artery is the traditional access site for the endovascular treatment of iliac artery stenoses. However, this approach is associated with complication rates as high as 2%, including retroperitoneal bleeding which carries high patient morbidity and mortality. Furthermore, the standard femoral approach is associated with longer recovery times and longer time to ambulation which are important considerations especially when performing procedures in an ambulatory setting. METHODS: Twelve patients were prospectively followed after treatment for symptomatic iliac artery stenosis via transpedal access. Under ultrasound guidance, one of the pedal arteries was visualized and accessed, and stenting of the iliac arteries were performed as per protocol. The patient was monitored immediately post procedure and clinical follow up was performed at one week and one month later. RESULTS: The average age of the patients was 71years old. 58% were male. Most patients had Rutherford class III symptoms. Successful stent placement was achieved in all 12 patients via transpedal access. No conversion to femoral access was required. No complications immediately post procedure nor at any time period during follow up were noted. Lower extremity arterial duplex at one month showed patent stents and patent pedal access site vessels in all patients. CONCLUSION: Transpedal arterial access may be a safe and feasible approach for iliac artery stenting. Given the possible benefits of avoiding femoral artery access, larger studies should be conducted directly comparing the different approaches. PMID- 27717581 TI - Establishing the ACORN National Practitioner Database: Strategies to Recruit Practitioners to a National Practice-Based Research Network. AB - OBJECTIVES: The purpose of this paper is to report on the recruitment and promotion strategies employed by the Australian Chiropractic Research Network (ACORN) project aimed at helping recruit a substantial national sample of participants and to describe the features of our practice-based research network (PBRN) design that may provide key insights to others looking to establish a similar network or draw on the ACORN project to conduct sub-studies. METHODS: The ACORN project followed a multifaceted recruitment and promotion strategy drawing on distinct branding, a practitioner-focused promotion campaign, and a strategically designed questionnaire and distribution/recruitment approach to attract sufficient participation from the ranks of registered chiropractors across Australia. RESULTS: From the 4684 chiropractors registered at the time of recruitment, the project achieved a database response rate of 36% (n = 1680), resulting in a large, nationally representative sample across age, gender, and location. This sample constitutes the largest proportional coverage of participants from any voluntary national PBRN across any single health care profession. CONCLUSIONS: It does appear that a number of key promotional and recruitment features of the ACORN project may have helped establish the high response rate for the PBRN, which constitutes an important sustainable resource for future national and international efforts to grow the chiropractic evidence base and research capacity. Further rigorous enquiry is needed to help evaluate the direct contribution of specific promotional and recruitment strategies in attaining high response rates from practitioner populations who may be invited to participate in future PBRNs. PMID- 27717582 TI - Glucuronide and sulfate conjugates of tetrabromobisphenol A (TBBPA): Chemical synthesis and correlation between their urinary levels and plasma TBBPA content in voluntary human donors. AB - 3,3',5,5'-Tetrabromobisphenol-A (TBBPA) is an important brominated flame retardant in epoxy, vinyl esters and polycarbonate resins. Previous studies have already shown the occurrence of its Phase II metabolites, TBBPA-glucuronide and sulfate conjugates, in human urine, after oral administration of TBBPA. The main objective of this work is to examine correlations among level of TBBPA in human blood and those of its Phase II metabolites in human urine. Four water-soluble TBBPA conjugates were synthesized, purified and characterized. An analytical protocol using solid-phase extraction and liquid chromatography-electrospray tandem mass spectrometry (SPE-LC-MS/MS) quantification was developed for the simultaneous analysis of these glucuronide and sulfate conjugates in human urine samples. TBBPA and its Phase II metabolites in paired human plasma and urine samples collected randomly from 140 voluntary donors in Hong Kong SAR, China, were determined. One or more TBBPA conjugates were detected in all of the urine samples, with concentration ranging from 0.19 to 127.24MUgg-1-creatinine. TBBPA was also quantified in >85% of the plasma and urine samples. Strong correlations were observed between TBBPA content in plasma and the total amount of TBBPA related compounds in urine.

AB - INTRODUCTION: In order to better understand the role of epigenetic influences in the etiology of Parkinson's disease (PD), we studied the expression of microRNAs in gyri cinguli of patients and controls. METHODS: Expression profiling of 744 well-characterized microRNAs in gyri cinguli from patients and controls using TaqMan array microRNA cards. Verification of significantly dysregulated microRNAs by SYBR Green qRT-PCR. RESULTS: First screen by TaqMan array identified 43 microRNAs that were upregulated in gyri cinguli from patients. Of those microRNAs, 13 are predicted to regulate at least one of six genes mutated in monogenic forms of PD (DJ-1, PARK2, PINK1, LRRK2, SNCA, and HTRA2). Five of these 13 microRNAs (-144, -199b, -221, -488, -544) were also found upregulated by SYBR Green qRT-PCR and are predicted to regulate either SNCA, PARK2, LRRK2 or combinations thereof. Consistently, expression of SNCA, PARK2, and LRRK2 was reduced in patients. An additional 5 out of ten potential target genes tested were downregulated. These are DRAM (DNA damage regulated autophagy modulator 1), predicted to be regulated by miR-144, EVC (Ellis Van Creveld Protein) by miR-221, ZNF440 (Zinc Finger Protein 440) by miR-199b, MTFMT (Mitochondrial Methionyl-tRNA Formyltransferase) by miR-488 and XIRP2 (Xin Actin Binding Repeat Containing) possibly controlled by miR-544a. CONCLUSION: The study identified five microRNAs that play a role in the etiology of Parkinson's disease likely by modifying expression of SNCA, PARK2, LRRK2 and additional genes required for normal cellular function.

PMID- 27717585 TI - High grade B-cell lymphoma with rearrangements of MYC and BCL2 and/or BCL6: Double hit and triple hit lymphomas and double expressing lymphoma. AB - Diffuse large B-cell lymphomas with aberrations in MYC, BCL2 and/or BCL6 by genetic alterations or protein expression represent a group of high grade B-cell lymphomas with inferior outcomes when treated with standard RCHOP chemotherapy. As a result, intensified induction regimens have been suggested in an effort to improve outcomes. Conclusions to date have largely been drawn from retrospective data although prospective data is slowly starting to emerge. Chemoimmunotherapy refractoriness is problematic and relapse rates are high. Patients with double hit lymphoma appear to have increased risk of CNS involvement and prophylaxis is recommended. There is insufficient evidence available to date to strongly recommend for or against consolidative stem cell transplant in this population. Collaborative clinical trials will be needed to establish a preferred therapeutic regimen and an appropriate standard of care in this unique group of patients with DLBCL.

AB - BACKGROUND: Drug overdose is the leading cause of injury-related fatality in the United States, and respiratory failure remains a major source of morbidity and mortality. OBJECTIVES: We aimed to identify the incidence and risk factors for endotracheal intubation after acute drug overdose. METHODS: This secondary data analysis was performed on a 5-year prospective cohort at two urban tertiary-care hospitals. The present study analyzed adult patients with suspected acute drug overdose to derive independent clinical predictors of endotracheal intubation. RESULTS: We analyzed 2497 patients with acute drug overdose, of whom 87 (3.5%) underwent endotracheal intubation. Independent clinical risk factors for endotracheal intubation were: younger age (odds ratio [OR] 0.97, 95% confidence interval [CI] 0.96-0.98), and history of obstructive lung disease (OR 6.6, 95% CI 3.5-12.3); however, heart failure had no association. Patients with obstructive lung disease had significantly more hypercapnia (mean difference 6.8 mm Hg, 95% CI 2.3-11.3) and a higher degree of acidemia (mean pH difference 0.04, 95% CI 0.01-0.07) than patients without obstructive lung disease. Lack of rapid sequence sedative/paralytic was associated with in-hospital fatality. Early complications of endotracheal intubation itself included desaturation (3.4%) and bradycardia (1%). CONCLUSIONS: Endotracheal intubation was infrequently performed on patients with acute drug overdose, and complications were rare when performed. Risk factors associated with endotracheal intubation included younger age and prior obstructive lung disease.

PMID- 27717592 TI - Euglycemic Diabetic Ketoacidosis with Elevated Acetone in a Patient Taking a Sodium-Glucose Cotransporter-2 (SGLT2) Inhibitor. AB - BACKGROUND: Sodium-glucose cotransporter-2 (SGLT2) inhibitor medications are a class of antihyperglycemic agents that increase urinary glucose excretion by interfering with the reabsorption of glucose in the proximal renal tubules. In May of 2015, the U.S. Food and Drug Administration released a warning concerning a potential increased risk of ketoacidosis and ketosis in patients taking these medications. CASE REPORT: We present a case of a 57-year-old woman with type 2 diabetes mellitus taking a combination of canagliflozin and metformin who presented with progressive altered mental status over the previous 2 days. Her work-up demonstrated a metabolic acidosis with an anion gap of 38 and a venous serum pH of 7.08. The serum glucose was 168 mg/dL. The urinalysis showed glucose > 500 mg/dL and ketones of 80 mg/dL. Further evaluation demonstrated an elevated serum osmolality of 319 mOsm/kg and an acetone concentration of 93 mg/dL. She was treated with intravenous insulin and fluids, and the metabolic abnormalities and her altered mental status resolved within 36 h. This was the first episode of diabetic ketoacidosis (DKA) for this patient. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Diabetic patients on SGLT2 inhibitor medications are at risk for ketoacidosis. Due to the renal glucose-wasting properties of these drugs, they may present with ketoacidosis with only mild elevations in serum glucose, potentially complicating the diagnosis. Acetone is one of the three main ketone bodies formed during DKA and it may be present at considerable concentrations, contributing to the serum osmolality.

AB - In craniomaxillofacial (CMF) surgery, a reliable way of simulating the soft tissue deformation resulted from skeletal reconstruction is vitally important for preventing the risks of facial distortion postoperatively. However, it is difficult to simulate the soft tissue behaviors affected by different types of CMF surgery. This study presents an integrated bio-mechanical and statistical learning model to improve accuracy and reliability of predictions on soft facial tissue behavior. The Rubin-Bodner (RB) model is initially used to describe the biomechanical behavior of the soft facial tissue. Subsequently, a finite element model (FEM) computers the stress of each node in soft facial tissue mesh data resulted from bone displacement. Next, the Generalized Regression Neural Network (GRNN) method is implemented to obtain the relationship between the facial soft tissue deformation and the stress distribution corresponding to different CMF surgical types and to improve evaluation of elastic parameters included in the RB model. Therefore, the soft facial tissue deformation can be predicted by biomechanical properties and statistical model. Leave-one-out cross-validation is used on eleven patients. As a result, the average prediction error of our model (0.7035mm) is lower than those resulting from other approaches. It also demonstrates that the more accurate bio-mechanical information the model has, the better prediction performance it could achieve. PMID- 27717595 TI - Probabilistic finite element method for large tumor radiofrequency ablation simulation and planning. AB - A challenging problem of radiofrequency ablation (RFA) in liver surgery is to accurately estimate the shapes and sizes of RFA lesions whose formation depends on intrinsic variations of the thermal-electrical properties of soft tissue. Large tumors, which can be as long as 10 cm or more, further complicate the problem. In this paper, a probabilistic bio-heating finite element (FE) model is proposed and developed to predict RFA lesions. Uncertainties of RFA lesions are caused by the probabilistic nature of five thermal-electrical liver properties: thermal conductivity, liver tissue density, specific heat, blood perfusion rate and electrical conductivity. Confidence levels of shapes and sizes of lesions are generated by the FE model incorporated with the mean-value first-order second moment (MVFOSM) method. Based on the probabilistic FE method, a workflow of RFA planning is introduced to enable clinicians to preoperatively view the predicted RFA lesions in three-dimension (3D) within a hepatic environment. Accurate planning of the RFA needle placements can then be achieved based on the interactive simulation and confidence level selection. PMID- 27717596 TI - Inositol as putative integrative treatment for PCOS. AB - Studies over the last decade have demonstrated that some polycystic ovary syndrome (PCOS) patients have abnormal insulin sensitivity (insulin resistance), independently from being overweight or obese. This induces the risk of developing type 2 diabetes in such PCOS patients. The use of insulin sensitizers (i.e. metformin), reduces such metabolic, and most hormonal, impairments. As metformin often induces side effects, new integrative strategies have been proposed to treat insulin resistance, such as the use of inositols. Such compounds are mainly represented in humans by two inositol stereoisomers: myo-inositol (MYO) and d chiro-inositol (DCI). MYO is the precursor of inositol triphosphate, a second messenger that regulates thyroid-stimulating hormone (TSH) and FSH as well as insulin. DCI derives from the conversion of myo-inositol via an insulin-dependent pathway. Several preliminary studies have indicated possible benefits of inositol therapy in PCOS patients, but to date no meta-analysis has been performed. This review aims to give clinical insights for the clinical use of inositol in PCOS. PMID- 27717597 TI - The Global Synanthrome Project: A Call for an Exhaustive Study of Human Associates.

PMID- 27717599 TI - Peptidic Biomaterials: From Self-Assembling to Regenerative Medicine. AB - Peptidic biomaterials represent a particularly exciting topic in regenerative medicine. Peptidic scaffolds can be specifically designed for biomimetic customization for targeted therapy. The field is at a pivotal point where preclinical research is being translated into clinics, so it is crucial to understand the theory and describe the status of this rapidly developing technology. In this review, we highlight major advantages and current limitations of self-assembling peptide-based biomaterials, and we discuss the most widely used classes of assembling peptides, describing recent and promising approaches in tissue engineering, drug delivery, and clinics. We also suggest design strategies and hurdles that still need to be overcome to fully exploit their therapeutic potential. PMID- 27717598 TI - [Statin associated myopathy in clinical practice. Results of DAMA study]. AB - BACKGROUND AND OBJECTIVE: Muscle symptoms, with or without elevation of creatin kinase are one of the main adverse effects of statin therapy, a fact that sometimes limits their use. The aim of this study was to evaluate the clinical characteristics of patients treated with statins who have complained muscle symptoms and to identify possible predictive factors. PATIENTS AND METHODS: A cross-sectional one-visit, non-interventional, national multicenter study including patients of both sexes over 18 years of age referred for past or present muscle symptoms associated with statin therapy was conducted. 3,845 patients were recruited from a one-day record from 2,001 physicians. RESULTS: Myalgia was present in 78.2% of patients included in the study, myositis in 19.3%, and rhabdomyolysis in 2.5%. Patients reported muscle pain in 77.5% of statin-treated individuals, general weakness 42.7%, and cramps 28.1%. Kidney failure, intense physical exercise, alcohol consumption (>30g/d in men and 20g/d in women) and abdominal obesity were the clinical situations associated with statin myopathy. CONCLUSIONS: Myalgia followed by myositis are the most frequent statin-related side effects. It should be recommended control environmental factors such as intense exercise and alcohol intake as well as abdominal obesity and renal function of the patient treated with statins. PMID- 27717600 TI - Opportunities and challenges when pooling milk samples using ELISA. AB - Testing large quantities of samples in order to detect one or more test-positive sample(s) is expensive and time-consuming. It is possible to optimize this process by pooling samples. Two frameworks to produce different hierarchical and non-hierarchical pooling schemes were tested and compared to standard pooling. Their efficiency and the potential savings were determined as a function of prevalence and the number of pooled samples. The potential benefit of pooling samples is dependent upon the changes in the analytical sensitivity and specificity of the test used when diluting test-positive samples by pooling. To illustrate this, the sensitivity of antibody ELISA on pooled samples of bovine milk for Salmonella Dublin, Mycobacterium avium spp. paratuberculosis, and bovine virus diarrhea was tested. For these milk assays, the analytical sensitivity decreased rapidly with increasing pool sizes. The efficiency of pooling is usually only measured by the number of tests performed, yet real savings depend on all the costs involved in the pooling process. These may differ between laboratories depending on the available equipment and the salaries of the technicians, among other factors. Therefore, several cost parameters were introduced to describe the total cost and thereby calculate the total savings. In terms of overall savings, both tested schemes were potentially optimal depending on the prevalence, possible pool size, and the cost of retesting. For the pool sizes of interest in this study, the three-stage hierarchical pooling scheme was often marginally more efficient in terms of the total number of tests. However, if the price of re-pooling was high, the two-stage scheme performed better in terms of total savings. In addition, for low prevalences and the possibility of pooling a large number of samples, the two-stage non-hierarchical test may be more efficient, both in terms of number of tests and overall cost. In order to apply these results in different laboratory settings, a free Shiny WebApp was developed, to compare several pooling schemes with different cost parameters.

AB - BACKGROUND: In most African countries the prevalence and effects of paediatric healthcare-associated infection (HCAI) and human immunodeficiency virus (HIV) infection are unknown. AIM: To investigate the burden, spectrum, risk factors, and impact of paediatric HCAI by prospective clinical surveillance at a South African referral hospital. METHODS: Continuous prospective clinical and laboratory HCAI surveillance using Centers for Disease Control and Prevention (CDC)/National Healthcare Safety Network (NHSN) definitions was conducted at Tygerberg Children's Hospital, South Africa, from May 1st to October 31st in 2014 and 2015. Risk factors for HCAI and associated mortality were analysed with multivariate logistic regression; excess length of stay was estimated using a confounder and time-matching approach. FINDINGS: HCAI incidence density was 31.1 per 1000 patient-days (95% CI: 28.2-34.2); hospital-acquired pneumonia (185/417; 44%), urinary tract infection (UTI) (45/417; 11%), bloodstream infection (BSI) (41/417; 10%), and surgical site infection (21/417; 5%) predominated. Device associated HCAI incidence in the paediatric intensive care unit (PICU) was high: 15.9, 12.9 and 16 per 1000 device-days for ventilator-associated pneumonia, central line-associated BSI and catheter-associated UTI, respectively. HCAI was significantly associated with PICU stay (odds ratio: 2.0), malnutrition (1.6), HIV infection (1.7), HIV exposure (1.6), McCabe score 'fatal' (2.0), comorbidities (1.6), indwelling devices (1.9), blood transfusion (2.5), and transfer in (1.4). Two-thirds of paediatric deaths were HCAI-associated, occurring at a median of four days from HCAI onset with significantly higher crude mortality for HCAI-affected vs HCAI-unaffected hospitalizations [24/325 (7.4%) vs 12/1022 (1.2%); P<0.001]. HCAI resulted in US$371,887 direct costs with an additional 2275 hospitalization days, 2365 antimicrobial days, and 3575 laboratory investigations. CONCLUSION: HCAI was frequent with significant morbidity, mortality, and healthcare costs. Establishment of HCAI surveillance and prevention programmes for African children is a public health priority. PMID- 27717601 TI - Direct Current Stimulation Alters Neuronal Input/Output Function. AB - BACKGROUND: Direct current stimulation (DCS) affects both neuronal firing rate and synaptic efficacy. The neuronal input/output (I/O) function determines the likelihood that a neuron elicits an action potential in response to synaptic input of a given strength. Changes of the neuronal I/O function by DCS may underlie previous observations in animal models and human testing, yet have not been directly assessed. OBJECTIVE: Test if the neuronal input/output function is affected by DCS METHODS: Using rat hippocampal brain slices and computational modeling, we provide evidence for how DCS modulates the neuronal I/O function. RESULTS: We show for the first time that DCS modulates the likelihood of neuronal firing for a given and fixed synaptic input. Opposing polarization of soma and dendrite may have a synergistic effect for anodal stimulation, increasing the driving force of synaptic activity while simultaneously increasing spiking probability at the soma. For cathodal stimulation, however, the opposing effects tend to cancel. This results in an asymmetry in the strength of the effects of stimulation for opposite polarities. CONCLUSIONS: Our results may explain the asymmetries observed in acute and long term effects of transcranial direct current stimulation.

In this third paper, new analyses show that the burden of poor development is higher than estimated, taking into account additional risk factors. National programmes are needed. Greater political prioritisation is core to scale-up, as are policies that afford families time and financial resources to provide nurturing care for young children. Effective and feasible programmes to support early child development are now available. All sectors, particularly education, and social and child protection, must play a role to meet the holistic needs of young children. However, health provides a critical starting point for scaling up, given its reach to pregnant women, families, and young children. Starting at conception, interventions to promote nurturing care can feasibly build on existing health and nutrition services at limited additional cost. Failure to scale up has severe personal and social consequences. Children at elevated risk for compromised development due to stunting and poverty are likely to forgo about a quarter of average adult income per year, and the cost of inaction to gross domestic product can be double what some countries currently spend on health. Services and interventions to support early childhood development are essential to realising the vision of the Sustainable Development Goals. PMID- 27717613 TI - Generation of global political priority for early childhood development: the challenges of framing and governance. AB - Despite progress, early childhood development (ECD) remains a neglected issue, particularly in resource-poor countries. We analyse the challenges and opportunities that ECD proponents face in advancing global priority for the issue. We triangulated among several data sources, including 19 semi-structured interviews with individuals involved in global ECD leadership, practice, and advocacy, as well as peer-reviewed research, organisation reports, and grey literature. We undertook a thematic analysis of the collected data, drawing on social science scholarship on collective action and a policy framework that elucidates why some global initiatives are more successful in generating political priority than others. The analysis indicates that the ECD community faces two primary challenges in advancing global political priority. The first pertains to framing: generation of internal consensus on the definition of the problem and solutions, agreement that could facilitate the discovery of a public positioning of the issue that could generate political support. The second concerns governance: building of effective institutions to achieve collective goals. However, there are multiple opportunities to advance political priority for ECD, including an increasingly favourable political environment, advances in ECD metrics, and the existence of compelling arguments for investment in ECD. To advance global priority for ECD, proponents will need to surmount the framing and governance challenges and leverage these opportunities. PMID- 27717616 TI - The IDEA model: A single equation approach to the Ebola forecasting challenge. AB - Mathematical modeling is increasingly accepted as a tool that can inform disease control policy in the face of emerging infectious diseases, such as the 2014-2015 West African Ebola epidemic, but little is known about the relative performance of alternate forecasting approaches. The RAPIDD Ebola Forecasting Challenge (REFC) tested the ability of eight mathematical models to generate useful forecasts in the face of simulated Ebola outbreaks. We used a simple, phenomenological single-equation model (the "IDEA" model), which relies only on case counts, in the REFC. Model fits were performed using a maximum likelihood approach. We found that the model performed reasonably well relative to other more complex approaches, with performance metrics ranked on average 4th or 5th among participating models. IDEA appeared better suited to long- than short-term forecasts, and could be fit using nothing but reported case counts. Several limitations were identified, including difficulty in identifying epidemic peak (even retrospectively), unrealistically precise confidence intervals, and difficulty interpolating daily case counts when using a model scaled to epidemic generation time. More realistic confidence intervals were generated when case counts were assumed to follow a negative binomial, rather than Poisson, distribution. Nonetheless, IDEA represents a simple phenomenological model, easily implemented in widely available software packages that could be used by frontline public health personnel to generate forecasts with accuracy that approximates that which is achieved using more complex methodologies. PMID- 27717615 TI - Nurturing care: promoting early childhood development. AB - The UN Sustainable Development Goals provide a historic opportunity to implement interventions, at scale, to promote early childhood development. Although the evidence base for the importance of early childhood development has grown, the research is distributed across sectors, populations, and settings, with diversity noted in both scope and focus. We provide a comprehensive updated analysis of early childhood development interventions across the five sectors of health, nutrition, education, child protection, and social protection. Our review concludes that to make interventions successful, smart, and sustainable, they need to be implemented as multi-sectoral intervention packages anchored in nurturing care. The recommendations emphasise that intervention packages should be applied at developmentally appropriate times during the life course, target multiple risks, and build on existing delivery platforms for feasibility of scale up. While interventions will continue to improve with the growth of developmental science, the evidence now strongly suggests that parents, caregivers, and families need to be supported in providing nurturing care and protection in order for young children to achieve their developmental potential.

AB - Early childhood development programmes vary in coordination and quality, with inadequate and inequitable access, especially for children younger than 3 years. New estimates, based on proxy measures of stunting and poverty, indicate that 250 million children (43%) younger than 5 years in low-income and middle-income countries are at risk of not reaching their developmental potential. There is therefore an urgent need to increase multisectoral coverage of quality programming that incorporates health, nutrition, security and safety, responsive caregiving, and early learning. Equitable early childhood policies and programmes are crucial for meeting Sustainable Development Goals, and for children to develop the intellectual skills, creativity, and wellbeing required to become healthy and productive adults. In this paper, the first in a three part Series on early childhood development, we examine recent scientific progress and global commitments to early childhood development. Research, programmes, and policies have advanced substantially since 2000, with new neuroscientific evidence linking early adversity and nurturing care with brain development and function throughout the life course.

METHODS: Normal skin and keloid tissue samples underwent histopathologic study and qPCR analysis. The expression of miR-21 and mRNA expression of Smad7, Col1A1, Col3A1 in fibroblasts derived from keloid tissue and normal skin tissue samples were detected by qPCR. Normal and keloid fibroblasts were transfected with miR-21 mimics or inhibitor respectively, and expression of Smad7, Col1A1 and Col3A1 were examined. After the normal fibroblasts were transfected with Smad7 siRNA, expression of Col1A1 and Col3A1 were detected by Western blot and qPCR analysis. RESULTS: Collagen was obviously thick and disorganized in keloid tissue. The expression of miR-21, Col1A1 and Col3A1 in keloid tissue and keloid derived fibroblasts were higher than that of normal counterparts, while the expression of Smad7 in keloid tissue and keloid-derived fibroblasts was lower. miR-21 mimics attenuated expression of Smad7, and enhanced the expression of Col1A1, Col3A1. Furthermore, the Smad7 siRNA increased expression of Col1A1and Col3A1. CONCLUSIONS: miR-21 promoted collagen production in keloid by negatively regulating the expression of the Smad7. PMID- 27717620 TI - Cyclosporine treatment for Stevens-Johnson syndrome/toxic epidermal necrolysis: Retrospective analysis of a cohort treated in a specialized referral center. AB - BACKGROUND: Treatment of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) remains controversial. OBJECTIVE: We sought to evaluate the impact of cyclosporine on hospital mortality in patients with SJS/TEN. METHODS: All patients with SJS and TEN admitted to our center from 2011 to 2014 were treated under a standardized protocol that allowed for cyclosporine therapy if the inclusion and exclusion criteria were met. Clinical data were reviewed retrospectively. Comparative analysis was made on mortality outcomes with patients treated with cyclosporine versus what was expected based on SCORTEN. RESULTS: In all, 44 patients were admitted during the study period. A total of 24 patients received cyclosporine and the remaining 20 patients were treated supportively. SCORTEN predicted 7.2 deaths and 3 were observed in the group treated with cyclosporine. In the group treated supportively, SCORTEN predicted 5.9 deaths and 6 deaths were observed. The standardized mortality ratio of SJS/TEN treated with cyclosporine was 0.42 (95% confidence interval 0.09-1.22). LIMITATION: Small sample size, retrospective design, and referral bias are limitations. CONCLUSION: The use of cyclosporine may improve mortality in SJS/TEN and needs to be validated in controlled studies.

PMID- 27717621 TI - Melanoma-associated leukoderma and vitiligo cannot be differentiated based on blinded assessment by experts in the field. AB - BACKGROUND: Melanoma-associated leukoderma (MAL) is a depigmenting disorder that can occur spontaneously in patients with melanoma. The differences in clinical presentation between MAL and vitiligo are not well defined. This may lead to misdiagnosing MAL as vitiligo, resulting in delayed detection of melanoma. OBJECTIVE: The objective of this study was to assess whether experts in the field can distinguish between MAL and vitiligo, and to assess if discriminative features can be identified. METHODS: We designed an image comparison study in which 4 experts in the field blindly assessed photographs followed by medical history of 11 patients with MAL and 33 with vitiligo. RESULTS: The assessors misdiagnosed 72.7% of MAL cases and marked 80.0% of them as typical vitiligo. The median age at onset of the leukoderma was higher (55 years, P = .001) in MAL. No discriminative features were found. LIMITATIONS: Sampling bias because of inclusion in tertiary referral center is a limitation. CONCLUSION: The clinical presentation of leukoderma in patients with melanoma resembles that of vitiligo. We propose "melanoma-associated vitiligo" as the more appropriate term for leukoderma in patients with melanoma. Clinicians should be aware that depigmentation in vitiligo can also be caused by melanoma-associated vitiligo and a total body inspection should be performed.

PMID- 27717623 TI - Association between the Family Nutrition and Physical Activity Screening Tool and obesity severity in youth referred to weight management. AB - BACKGROUND: The Family Nutrition and Physical Activity Screening Tool (FNPA) evaluates family behavioural and environmental factors associated with pediatric obesity, but it is unknown if FNPA scores differ among youth across obesity severities. Our aim was to determine the association between the FNPA and obesity severity in youth referred to weight management. METHODS: Upon initiating treatment, height, weight, and the FNPA were collected according to standard procedures. Cut-points for overweight/obesity, severe obesity (SO) class 2, and SO class 3 were calculated. FNPA scores were compared across weight status groups using analysis of covariance, and odds of SO across FNPA quartiles were evaluated with multiple logistic regression. RESULTS: Participants included 564 5-18year old who initiated treatment and completed the FNPA. After adjustment, FNPA scores differed by weight status with higher/healthier scores in youth with overweight/obesity (56.6+/-8.5) when compared to those with SO class 2 (55.0+/ 7.1; p=0.015) or SO class 3 (53.6+/-9.0; p<0.001). Compared to those in the highest FNPA quartile, youth in the 2nd quartile had 1.8 (95% CI: 1.1, 2.9) times higher odds of SO, and those in the lowest FNPA quartile had 2.1 (95% CI: 1.3, 3.4) times higher odds of SO. Youth with SO had unhealthier subscale scores among 6 of 10 constructs, including nutritional, physical activity, sedentary, and sleep behaviours. CONCLUSIONS: Results suggest a consistent inverse relationship between the FNPA and adiposity among youth presenting for weight management. The FNPA is a useful metric for programs and clinicians targeting family behaviours and the home environment to combat obesity. PMID- 27717624 TI - Differences in Pediatric Non-Interventional Radiology Procedural Sedation Practices and Adverse Events by Registered Nurses and Physicians. AB - PURPOSE: The purpose of this study was to determine differences in sedation related adverse events according to the type of provider monitoring and delivering sedation. DESIGN AND METHODS: A retrospective, cross-sectional, correlational design using secondary data from the Pediatric Sedation Research Consortium database was used for this study. RESULTS: A sample of 36,352 cases (0 14 years of age) sedated and monitored for diagnostic radiology procedures by three types of providers (registered nurses [RNs] alone, physicians (MDs) alone, or registered nurse + physician [RN+MD sedation teams]) were compared. Patients sedated by RNs alone or MDs alone had lower odds of unanticipated adverse events (odds ratios 0.46 and 0.53, respectively; p<0.0001) compared with RN+MD sedation provider teams. CONCLUSIONS: Team skills may be an important competency for RN+MD sedation teams in the non-interventional radiology setting. PRACTICE IMPLICATIONS: This study can inform clinicians, administrators, and quality improvement managers of the differences in adverse event outcomes of pediatric radiology procedures when RN+MD teams provide sedation compared with RNs or MDs alone. PMID- 27717625 TI - Lumbar synovial cysts: presentation of a series of 10 cases and literature review. AB - INTRODUCTION: Although they are freqqently described in the literature, lumbar synovial cysts are a relative uncommon cause of low back and radicular leg pain. OBJECTIVE: To evaluate the treatment and surgical outcomes of the lumbar synovial cysts operated on in our hospital during a 5 year period. MATERIAL AND METHODS: A retrospective study was conducted on patients surgically treated in our department from August 2009 to September 2014, using a visual analogue scale for the clinical follow-up in the first year after surgery. RESULTS: After the surgical treatment (surgical removal of the synovial cyst with or without instrumented arthrodesis with transpedicular screws) of 10 patients (5 female and 5 male) with a mean age of 70.2 years (range 50-80), the clinical outcome was satisfactory in 80% of the patients, with the resolving of their symptoms. CONCLUSIONS: Lumbar synovial cysts have to be considered in the differential diagnosis in patients with low back and radicular leg pain. The majority of the patients are in their sixties and have lumbar degenerative spondylopathy. Nowadays, surgical resection of the lumbar synovial cysts and spinal fusion are the recommended treatment, because it is thought that the increased movement of the spine is one to the causes of the cyst formation. More studies are still needed, hence the relevance of this article. PMID- 27717626 TI - Functional outcome after transphyseal anterior cruciate ligament reconstruction in young patients with open growth plates. AB - BACKGROUND: This study evaluates sports ability, rotational laxity and potential growth changes in children after transphyseal ACL reconstruction with metaphyseal fixation technique, considering physis biology by placing drill holes vertically in the femoral anatomic origin in order to reduce volumetric injury to the physis. METHODS: In this retrospective trial of 42 patients data were collected. Thirty-seven were reviewed measuring rotational laxity and anteroposterior tibial translation using the Laxitester (ORTEMA Sport Protection, Markgroeningen, Germany) and the KT1000. Clinical examination was evaluated with the IKDC 2000 knee examination form. Leg axis was determined with digital photography and leg length was assessed clinically. Sports ability was assessed with questionnaires including subjective IKDC, Tegner Activity Scale, Activity Rating Scale and a questionnaire on sports and level of sports. RESULTS: Mean follow-up was 24.9months. Mean age at surgery was 13.2years in boys and 13.1years in girls. IKDC 2000 grading was A or B in 28 patients and C in nine patients. Significant increased anterior tibial translation was observed in neutral position and in external tibia rotation. No growth abnormalities were seen. Fifty-seven percent of the patients were able to participate in competitive sports at follow-up. CONCLUSION: Transphyseal ACL reconstruction with metaphyseal fixation in children with open growth plates can be done with low risk of growth changes. Return to competitive sports is possible although low rotational laxity still exists. LEVEL OF EVIDENCE: IV. PMID- 27717627 TI - Preventative Vaccines for Zika Virus Outbreak: Preliminary Evaluation. AB - Since it emerged in Brazil in May 2015, the mosquito-borne Zika virus (ZIKV) has raised global concern due to its association with a significant rise in the number of infants born with microcephaly and neurological disorders such as Guillain-Barre syndrome. We developed prototype subunit and adenoviral-based Zika vaccines encoding the extracellular portion of the ZIKV envelope gene (E) fused to the T4 fibritin foldon trimerization domain (Efl). The subunit vaccine was delivered intradermally through carboxymethyl cellulose microneedle array (MNA). The immunogenicity of these two vaccines, named Ad5.ZIKV-Efl and ZIKV-rEfl, was tested in C57BL/6 mice. Prime/boost immunization regimen was associated with induction of a ZIKV-specific antibody response, which provided neutralizing immunity. Moreover, protection was evaluated in seven-day-old pups after virulent ZIKV intraperitoneal challenge. Pups born to mice immunized with Ad5.ZIKV-Efl were all protected against lethal challenge infection without weight loss or neurological signs, while pups born to dams immunized with MNA-ZIKV-rEfl were partially protected (50%). No protection was seen in pups born to phosphate buffered saline-immunized mice. This study illustrates the preliminary efficacy of the E ZIKV antigen vaccination in controlling ZIKV infectivity, providing a promising candidate vaccine and antigen format for the prevention of Zika virus disease.

AB - INTRODUCTION AND AIMS: Rectal prolapse is common in the elderly, having an incidence of 1% in patients over 65years of age. The aim of this study was to evaluate the safety and feasibility of a new endoluminal procedure for attaching the previously mobilized rectum to the anterior abdominal wall using an endoscopic fixation device. MATERIALS AND METHODS: The study is a single-arm phasei experimental trial. Under general anesthesia, total rectal prolapse was surgically reproduced in five pigs. Transanal endoscopic reduction of the rectal prolapse was performed. The best site for transillumination of the abdominal wall, suitable for rectopexy, was identified. The EndoLifter was used to approximate the anterior wall of the proximal rectum to the anterior abdominal wall. Two percutaneous rectopexies were performed by puncture with the Loop FixtureII Gastropexy Kit(r) at the preset site of transillumination. After the percutaneous rectopexies, rectoscopy and exploratory laparotomy were performed. Finally, the animals were euthanized. RESULTS: The mean procedure time was 16min (11-21) and the mean length of the mobilized specimen was 4.32cm (range 2.9 5.65cm). A total of 10 fixations were performed with a technical success rate of 100%. There was no evidence of postoperative rectal prolapse in any of the animals. The EndoLifter facilitated the process by allowing the mucosa to be held and manipulated during the repair. CONCLUSIONS: Endoscopic-assisted percutaneous rectopexy is a safe and feasible endoluminal procedure for fixation of the rectum to the anterior abdominal wall in experimental animals.

PMID- 27717632 TI - Risk of poor development in young children in low-income and middle-income countries: an estimation and analysis at the global, regional, and country level. AB - BACKGROUND: A 2007 study published in The Lancet estimated that approximately 219 million children aged younger than 5 years were exposed to stunting or extreme poverty in 2004. We updated the 2004 estimates with the use of improved data and methods and generated estimates for 2010. METHODS: We used country-level prevalence of stunting in children younger than 5 years based on the 2006 Growth Standards proposed by WHO and poverty ratios from the World Bank to estimate children who were either stunted or lived in extreme poverty for 141 low-income and middle-income countries in 2004 and 2010. To avoid counting the same children twice, we excluded children jointly exposed to stunting and extreme poverty from children living in extreme poverty. To examine the robustness of estimates, we also used moderate poverty measures. FINDINGS: The 2007 study underestimated children at risk of poor development. The estimated number of children exposed to the two risk factors in low-income and middle-income countries decreased from 279.1 million (95% CI 250.4 million-307.4 million) in 2004 to 249.4 million (209.3 million-292.6 million) in 2010; prevalence of children at risk fell from 51% (95% CI 46-56) to 43% (36-51). The decline occurred in all income groups and regions with south Asia experiencing the largest drop. Sub-Saharan Africa had the highest prevalence in both years. These findings were robust to variations in poverty measures. INTERPRETATION: Progress has been made in reducing the number of children exposed to stunting or poverty between 2004 and 2010, but this is still not enough. Scaling up of effective interventions targeting the most vulnerable children is urgently needed. FUNDING: National Institutes of Health, Bill & Melinda Gates Foundation, Hilton Foundation, and WHO. PMID- 27717633 TI - Failure of communication: a patient's story. AB - The first author, a patient who underwent elective caesarean section and felt pain necessitating conversion to general anaesthesia, describes the experience with particular reference to the perceived poor communication between her and her anaesthetist. This extended from the preoperative visit to the information provided to her general practitioner after discharge. She makes several suggestions which would have made her experience, and those of other patients in similar circumstances, less traumatic. The second author, who had no involvement in events and works in a different Trust, comments upon the events from the perspective of an obstetric anaesthetist. PMID- 27717634 TI - Clinical effectiveness of transversus abdominis plane (TAP) blocks for pain relief after caesarean section: a meta-analysis. AB - BACKGROUND: The effectiveness of transversus abdominis plane (TAP) blocks for acute pain relief after caesarean section, in comparison to normal practice, remains uncertain. METHODS: Electronic literature databases were searched from inception to May 2016 for randomised controlled trials that assessed the effectiveness of TAP blocks following caesarean section. Trials were eligible if comparisons were made against no block or placebo, and/or intrathecal morphine. Risk of bias was assessed using the Cochrane tool. Data for consistent outcomes were subject, where possible, to meta-analysis and presented as either mean differences with 95% confidence intervals or incidence of a particular event. RESULTS: Twenty published studies fulfilled our inclusion criteria. TAP blocks significantly reduced pain at rest both when compared with placebo or no TAP blocks (-0.96, 95% CI -1.67 to -0.25, P=0.008) and intrathecal morphine (1.10, 95% CI 0.59 to 1.60, P<0.0001). Both these comparisons showed the greatest improvement with pain on movement, (-1.58, 95% CI -2.69 to -0.47, P=0.005 and 1.35, 95% CI 0.76 to 1.94, respectively, P<0.00001). Morphine consumption was significantly reduced with TAP blocks when compared to placebo or no TAP blocks ( 15.88, 95% CI -22.02 to -9.73, P<0.00001). This significance was lost when TAP blocks were both compared to intrathecal morphine (0.89, 95% CI -0.64 to 2.43, P=0.25) and given in co-administration (0.00, 95% CI -0.10 to 0.10, P=1.00). CONCLUSION: TAP blocks provide effective analgesia after caesarean section; however, additional benefits are more difficult to demonstrate when long-acting intrathecal opioids are administered. PMID- 27717635 TI - Dose-response of intrathecal morphine when administered with intravenous ketorolac for post-cesarean analgesia: a two-center, prospective, randomized, blinded trial. AB - BACKGROUND: The appropriate dose of intrathecal morphine for post-cesarean analgesia is unclear. With the inclusion of routine non-steroidal anti inflammatory drugs, the required dose of morphine may be significantly less than the 200-300MUg common a decade ago. We performed a two-center, prospective, randomized, blinded trial comparing three doses of intrathecal morphine, combined with routine intravenous ketorolac, in 144 healthy women undergoing elective cesarean delivery. METHODS: Patients received an intrathecal injection of hyperbaric bupivacaine 12mg, fentanyl 15MUg and a randomized dose of 50, 100, or 150MUg morphine in a volume of 2.2mL. Patients received intravenous ketorolac 30mg before leaving the operating room and 15mg intravenously every 6h for the duration of the study (24h). All received postoperative patient-controlled intravenous morphine. The primary endpoint was total intravenous morphine administered postoperatively over 24h, analyzed using mixed model regression. RESULTS: There were no differences between dose groups (or institutions) in intravenous morphine use over 24h. Visual analog scale scores for pain and nausea did not differ. Pruritus was greater in the 100 and 150MUg groups than the 50MUg group at 6h and 12h, but there was no difference between groups in nausea or pruritus treatments. Respiratory depression or significant sedation did not occur. CONCLUSION: The dose-response relationship of intrathecal morphine for multimodal post-cesarean analgesia suggests that 50MUg produces analgesia similar to that produced by either 100MUg or 150MUg. PMID- 27717636 TI - The effect of dalteparin on thromboelastography in pregnancy: an in vitro study. AB - BACKGROUND: Dalteparin is often used for prophylaxis or treatment of venous thromboembolism during pregnancy, yet there is no laboratory test to accurately reflect its clinical activity. Thromboelastography is a point-of-care monitor of whole blood coagulation. The aim of this study was to determine if serial doses of dalteparin added in vitro to whole blood samples from term, pregnant women are detectable as changes in thromboelastography parameters. METHODS: Thirty healthy parturients presenting for elective caesarean section were recruited. Dalteparin was added to whole blood samples to yield final concentrations of 0 (control), 0.05, 0.25, 0.5, 0.75 and 1.0U/mL anti-Xa activity. Thromboelastography tracings were obtained for all six samples using the standard kaolin protocol. RESULTS: Significant differences were noted in median thromboelastography r time, k time, alpha angle and maximal amplitude between non-anticoagulated (?0.05U/mL) and samples ?0.5U/mL (P<0.05). The r time and k time presented with the highest sensitivities of 97.5 and 84.0, respectively. CONCLUSION: This pilot study provides proof-of-concept that thromboelastography can discriminate differences in blood anticoagulated with varying doses of dalteparin in a dose-dependent manner. This suggests that thromboelastography may be a feasible monitor of anticoagulation in the presence of dalteparin in maternal whole blood and may potentially translate to a point-of-care test that can be used to determine real time coagulation status in patients. PMID- 27717638 TI - Photoacoustic calorimetry studies of CO photo-dissociation from chloramine-T modified horse heart cytochrome-c. AB - Treatment of horse heart Cytochrome-c (Cc) with N-chloro-4-toluosulfonamide (Chloramine-t, CT) results in the oxidation of methionine (Met) residues to the corresponding sulfoxide including the distal heme ligand, Met80. The resulting Fe sulfoxide coordination is sufficiently labile in the ferrous form to be displaced by gaseous ligands, including CO. Photolysis of the CO-CT-Cc complex provides an opportunity to examine ligand binding dynamics that are associated with a relatively rigid distal heme pocket. In this work, photoacoustic calorimetry (PAC) was utilized to obtain the kinetics as well as enthalpy and molar volume changes subsequent to CO photo-dissociation from CO-CT-Cc. Previous photolysis studies of CO-CT-Cc have led to a proposed model for ligand recombination in which the Met80-sulfoxide and CO recombine with the heme on relatively slow timescales (50 MUs and ~500 MUs, respectively). The PAC data presented here reveals two additional kinetic phases with lifetimes of <20 ns and 534 +/- 75 ns. The fast phase (<20 ns) is associated with an DeltaH of 44 +/- 5 kcal mol-1 and DeltaV of -0.5 +/- 0.5 mL mol-1, whereas the slower phase (534 ns) is associated with a small DeltaH of 2 +/- 3 kcal mol-1 and DeltaV of 1 +/- 0.5 mL mol-1.

AB - Whether primary or secondary, limb lymphedema is a relatively common disease whose impact on the quality of life of patients is important. Although the microsurgical reconstruction techniques seem to be the techniques of choice in the treatment of limb lymphedema, no consensus about treatment of limb lymphedema has yet been defined. Considering the advantages and disadvantages of surgical techniques and their impact on the quality of life of patients, we propose a surgical treatment algorithm of limb lymphedema. PMID- 27717639 TI - The preferential heterodimerization of human small heat shock proteins HSPB1 and HSPB6 is dictated by the N-terminal domain. AB - Small heat shock proteins are ATP-independent molecular chaperones. Their function is to bind partially unfolded proteins under stress conditions. In vivo, members of this chaperone family are known to preferentially assemble together forming large, polydisperse heterooligomers. The exact molecular mechanisms that drive specific heteroassociation are currently unknown. Here we study the oligomers formed between human HSPB1 and HSPB6. Using small-angle X-ray scattering we could characterize two distinct heterooligomeric species present in solution. By employing native mass spectrometry we show that such assemblies are formed purely from heterodimeric building blocks, in line with earlier cross linking studies. Crucially, a detailed analysis of truncation variants reveals that the preferential association between these two sHSPs is solely mediated by their disordered N-terminal domains.

PMID- 27717642 TI - The Greenland shark: A new challenge for the oxidative stress theory of ageing? AB - The free radical theory of ageing predicts that long-lived species should be more resistant to oxidative damage than short-lived species. Although many studies support this theory, recent studies found notable exceptions that challenge the generality of this theory. In this study, we have analysed the oxidative status of the Greenland shark (Somniosus microcephalus), which has recently been found as the longest living vertebrate animal known to science with a lifespan of at least 272years. As compared to other species, the Greenland shark had body mass corrected values of muscle glutathione peroxidase and red blood cells protein carbonyls (metric of protein oxidative damage) above 75 percentile and below 25 percentile, respectively. None of the biochemical metrics of oxidative status measured in either skeletal muscle or red blood cells were correlated with maximum lifespan of species. We propose that the values of metrics of oxidative status we measured might be linked to ecological features (e.g., adaptation to cold waters and deep dives) of this shark species rather to its lifespan.

This systematic review and meta-analysis aimed to compare the success and complication rates associated with three pulmonary nodule localization methods for video-assisted thoracoscopic surgery (VATS): hook-wire localization, microcoil localization, and lipiodol localization. METHODS: We searched the PubMed, MEDLINE, and EMBASE databases for prospective or retrospective English language studies of VATS localization in adult patients. A noncomparative, random effects model-based meta-analysis was performed to obtain pooled success and complication rates for the three localization methods. RESULTS: A total of 46 clinical studies were enrolled, including 30, 9, and 7 studies of hook-wire, microcoil, and lipiodol localization, respectively. The successful targeting rates for hook-wire, microcoil, and lipiodol localization were 0.98 (95% CI, 0.97-0.99), 0.98 (95% CI, 0.96-0.99), and 0.99 (95% CI, 0.98 1.00), respectively, with corresponding successful operative field targeting rates of 0.94 (95% CI, 0.91-0.96), 0.97 (95% CI, 0.95-0.98), and 0.99 (95% CI, 0.98-1.00), respectively. In addition, the successful VATS rates with hook-wire, microcoil, and lipiodol localization were 0.96 (95% CI, 0.94-0.97), 0.97 (95% CI, 0.94-0.99), and 0.99 (95% CI, 0.98-1.00), respectively. Regarding complications, hook-wire, microcoil, and lipiodol localization were associated with pneumothorax rates of 0.35 (95% CI, 0.28-0.43), 0.16 (95% CI, 0.07-0.34), and 0.31 (95% CI, 0.20-0.46), respectively and hemorrhage rates of 0.16 (95% CI, 0.11-0.23), 0.06 (95% CI, 0.03-0.11), and 0.12 (95% CI, 0.05-0.23), respectively. CONCLUSIONS: All three localization methods yielded similarly highly successful targeting rates. However, hook-wire localization had a relatively lower successful operative field targeting rate because of dislodgement or migration. Lipiodol localization had the highest overall success rate, and microcoil localization yielded the lowest complication rates.

AB - Vitamin D inadequacy, frequently underdiagnosed, affects people of all age groups worldwide. This prospective study aims at determining the percentage of inadequate vitamin D levels among students and evaluating the impact of pharmacist counseling on raising the awareness of the importance of sun exposure and adequate vitamin D intake. A total of 160 university students were recruited. Blood samples were taken to check the vitamin D, calcium, and phosphorous levels. Vitamin D levels ?30ng/mL were defined as inadequate. Scores were given to the questions and aimed at gathering patient knowledge about vitamin D before and after pharmacist counseling. A total of 115 (71.87%) patients had vitamin D levels <30ng/mL, with a mean vitamin D serum level of 16.80+/-5.85ng/mL. The mean level of calcium was 9.51+/-1.23mg/dL and, of phosphorus 3.62+/-0.95mg/dL. The mean difference in the knowledge score of the recommended daily amount of vitamin D before and after pharmacist counseling was 2.81 versus 5.88 (p<0.001). Concerning patient education for diseases and drugs that affect vitamin D levels, pharmacist counseling was effective in raising the awareness (p<0.001). Given that vitamin D inadequacy is linked to many disease progressions, it is important that health professionals provide interventional strategies and education measures to correct inadequate levels in patients of all age groups. PMID- 27717645 TI - Transorganogenesis and transdifferentiation in C. elegans are dependent on differentiated cell identity. AB - The differentiated cell identities and structure of fully formed organs are generally stable after their development. In contrast, we report here that development of the C. elegans proximal somatic gonad (hermaphrodite uterus and spermathecae, and male vas deferens) can be redirected into intestine-like organs by brief expression of the ELT-7 GATA transcription factor. This process converts one developing organ into another and can hence be considered "transorganogenesis." We show that, following pulsed ELT-7 expression, cells of the uterus activate and maintain intestine-specific gene expression and are transformed at the ultrastructural level to form an epithelial tube resembling the normal intestine formed during embryogenesis. Ubiquitous ELT-7 expression activates intestinal markers in many different cell types but only cells in the somatic gonad and pharynx appear to become fully reprogrammed. We found that ectopic expression of other endoderm-promoting transcription factors, but not muscle- or ectoderm- promoting transcription factors, redirects the fate of these organs, suggesting that pharyngeal and somatic gonad cells are specifically competent to adopt intestine identity. Although the intestine, pharynx, and somatic gonad are derived from distant cell lineages, they all express the PHA 4/FoxA transcription factor. While we found that post-embryonic PHA-4 is not necessary for pharynx or uterus reprogramming and PHA-4 is not sufficient in combination with ELT-7 to induce reprogramming in other cells types, knock down of PHA-4 during embryogenesis, which abolishes normal pharynx differentiation, prevents pharyngeal precursors from being reprogrammed into intestine. These results suggest that differentiated cell identity determines susceptibility to transdifferentiation and highlight the importance of cellular context in controlling competency for reprogramming. PMID- 27717647 TI - Bariatric Embolization: Pilot Study on the Impact of Gastroprotective Agents and Arterial Distribution on Ulceration Risk and Efficacy in a Porcine Model. AB - PURPOSE: To assess whether the number of fundal arteries embolized and use of gastroprotective agents have an impact on ghrelin suppression and gastric ulceration rates. MATERIALS AND METHODS: Twenty-two healthy, growing swine (mean, 38.4 kg; range, 30.3-47.0 kg) were evaluated. Six control swine underwent a sham procedure. Gastric embolization was performed by the infusion of 40-um microspheres selectively into some or all gastric arteries supplying the gastric fundus. In group 1, 6 swine underwent embolization of all 4 arteries to the gastric fundus. In group 2, 5 swine underwent embolization of 2 gastric fundal arteries. In group 3, 5 swine underwent embolization of 1 gastric fundal artery. Animals in groups 2 and 3 were treated with gastroprotective agents (sucralfate and omeprazole). Weight and fasting plasma ghrelin levels were analyzed at baseline and at week 4. Upon animal euthanasia, gross analysis was performed for identification of ulcers. RESULTS: Only group 1 animals exhibited changes in serum ghrelin levels that rendered them significantly lower than those in control animals (P = .049). Group 3 animals exhibited marked elevations in serum ghrelin levels compared with control animals (P = .001). Gross pathologic evaluation revealed 0 ulcers in the control animals, 3 ulcers (50%) in group 1, 2 ulcers (40%) in group 2, and 2 ulcers (40%) in group 3. CONCLUSIONS: Administration of gastroprotective agents and embolization of fewer arteries to the gastric fundus did not prevent gastric ulceration in treated animals. Only animals that underwent embolization of all gastric arteries exhibited significant decreases in serum ghrelin levels.

AB - Reduced vancomycin susceptibility of methicillin-resistant Staphylococcus aureus (MRSA) is a worldwide problem. Unfortunately, its genetic marker and molecular mechanisms remained unknown. This study investigated differential phenotypic characteristic and protein expression profiles among three groups of MRSA isolates, including vancomycin-susceptible S. aureus (VSSA), heterogeneous vancomycin-intermediate S. aureus (hVISA) and vancomycin-intermediate S. aureus (VISA) (n = 7 isolates/group). Phenotypic characteristic revealed significant greater number of isolates with non-spreading colony in VISA as compared to both VSSA and hVISA groups. 2-DE followed by nanoLC-MS/MS analyses revealed increased glyceraldehyde 3-phosphate dehydrogenase (GAPDH) in both hVISA and VISA, whereas 50S ribosomal protein L14 (RplN) and DNA-binding protein II (Hup) were increased only in VISA. The non-spreading colony and GAPDH level of MRSA may be used as the markers for differentiation of VSSA, hVISA and VISA. PMID- 27717649 TI - Correlation of clinical, laboratory and drug susceptibility profiles in 176 patients with culture positive TBM in a tertiary neurocare centre. AB - Drug resistance has increased the difficulties in control of tuberculosis infection. The present study evaluated the clinical and laboratory features among tuberculous meningitis (TBM) patients and the drug susceptibility of Mycobacterium tuberculosis (M.tb) isolated from CSF. Out of 698 CSF samples, 176 (25.21%) were M.tb culture positive. Among the clinical signs and symptoms, fever, headache and altered sensorium were found to be statistically significant (P<0.05). ELISA was a better predictor of disease and found to be statistically significant (P<0.001) in culture-proven TBM cases. Totally, 57 (32.4%) isolates were resistant to one or more drugs that include 5 (2.8%) multidrug-resistant isolates. In conclusion, the search for antibody in CSF and also CSF chloride can represent as an adjunct in the diagnosis of TBM. Screening of drug susceptibility is a very important factor and would help in better management of the disease. PMID- 27717650 TI - The distribution and drug susceptibilities of clinical Candida species in TSARY 2014. AB - The species distribution and drug susceptibilities of 1106 Candida isolates collected in Taiwan Surveillance of Antimicrobial Resistance of Yeasts (TSARY) in 2014 were determined. Candida albicans is still the dominant species, accounting for 35.9%, followed by 28.3% C. glabrata, 26.6% C. tropicalis, 5.2% C. parapsilosis, 1.0% C. krusei, and 3.0% of 13 other species. Interestingly, the prevalence of candidemia caused by C. glabrata in the present study is significantly higher than that in previous three surveys (39/220 vs. 54/471, P=0.025). We found that 31 (2.8%), 24 (2.2%), 1 (0.09%), and 0 isolates were resistant to fluconazole, voriconazole, anidulafungin, and amphotericin B, respectively. There is a significant increase in fluconazole (P=0.00002) and voriconazole (P=0.00006) resistant rates when compared to the isolates collected in 2010. Importantly, all the 24 voriconazole resistant isolates identified were also resistant to fluconazole. Hence, cross-resistance among azole-type drugs is an emerging issue for managing fungal infections.

AB - Inquilinus limosus is a slow growing, gram-negative, oxidase-positive, non fermentative bacillus that is rarely isolated from clinical samples. When clinically identified, I. limosus is almost exclusively isolated from the respiratory tracts of patients with cystic fibrosis (CF). We report the first case of I. limosus isolation from a pulmonary specimen in an individual without a diagnosis of CF. A review of the English-language literature has been made and shows 33 cases (excluding the present report) in which I. limosus was isolated from the respiratory tracts of patients. Our patient, at 60years of age, is more than two decades older than the any previously reported patient. Similar to previous reports, the I. limosus isolated from her lungs demonstrated intrinsic multidrug resistance. The pathogenicity, clinical relevance, and optimal therapeutic management of I. limosus remains largely unknown due to its infrequent recovery from clinical samples. PMID- 27717652 TI - Synthesis and evaluation of the structural elements in alkylated tetrahydroisoquinolines for binding to CNS receptors. AB - Diseases of the CNS are often complex and involve multiple receptor systems and thus, the treatment options for these diseases must focus on targeting the multiple receptors implicated in the various disorders. Schizophrenia and depression are examples of such diseases and their pharmacotherapy thus depends on agents which target multiple receptors including the dopamine, serotonin and even cholinergic receptors at the same time. In our previous campaign to find multi-receptor ligands, we have identified the benzothiazole 1a as an initial lead molecule. In the current work, we have expanded the structure affinity relationship (SAFIR) of 1a resulting in the identification of a partially restrained butyrophenone 3j as a potent and selective dual 5-HT1A and 5-HT7 receptor ligand. It is expected that compound 3j may serve as a new lead for further development in our search for newer and novel ligands with the potential to treat diseases of CNS origin. PMID- 27717653 TI - The time dependence of the effect of ischemic preconditioning on successive sprint swimming performance. AB - OBJECTIVES: The present study aimed to determine the effects of ischemic preconditioning on performance in three successive 50-m swimming trials and to measure stroke rate, stroke length and blood lactate accumulation. DESIGN: Counterbalanced, repeated-measures cross-over study. METHODS: On two separate days, eleven competitive male swimmers (20+/-3 years, 182+/-5cm, 77+/-5kg) performed three successive 50-m trials in a 50-m swimming pool, preceded by intermittent bilateral cuff inflation (4* 5-min of blood flow restriction+5-min of cuff deflation) at either 220 for thighs and 180mmHg for arms (ischemic preconditioning) or 20mmHg for both limbs (control-treatment). The 50-m trials were conducted 1-, 2-, and 8-h after the procedure. RESULTS: While no ergogenic effect of ischemic preconditioning was observed for 1-h (0.4%, 95% confidence limits of +/-0.6%, p=0.215), there were clear beneficial effects of ischemic preconditioning on 2- and 8-h (1.0% and 1.2%, respectively; 95% confidence limits of +/-0.6% in both cases, p<=0.002). Furthermore, ischemic preconditioning increased blood lactate accumulation in 2-(p<0.001) and 8-h (p=0.010) and stroke rate for 2- and 8-h in specific 10-m segments (p<0.05). CONCLUSIONS: These findings suggest a time-dependent effect of ischemic preconditioning on 50-m swimming performance for competitive athletes, with the time window of the beneficial effect starting after about 2-h and lasting for at least 8-h after ischemic preconditioning. This change in performance was accompanied by an increase in blood lactate accumulation and faster strokes in front crawl.

AB - The aim of this study was to assess the combined effect of dimethylacetamide (DMA) and two non-permeating cryoprotective agents, trehalose and sucrose, on the quality of post-thaw chicken semen. Adult Lohmann roosters (n = 27) were used. Semen was processed according to the following treatments: Lake pre-freezing extender +6% DMA (LPF, control treatment), LPF + 0.1 M trehalose (LPF-T treatment), LPF + 0.1 M sucrose (LPF-S treatment) and LPF + 0.1 M trehalose + 0.1 M sucrose (LPF-TS treatment). Semen was loaded into straws and frozen in nitrogen vapour. Sperm quality (viability, mobility and kinetic parameters) was assessed immediately after thawing (T0) and at 5 (T5), 10 (T10) and 15 min (T15) thereafter. The different cryodiluent combinations significantly affected the kinetic parameters. The presence of trehalose, alone or with sucrose, combined with DMA improved the quality of motion in cryopreserved sperm in comparison to DMA alone (LPF) and DMA with sucrose (LPF-S). In particular, the highest values in linearity (LIN) and wobble (WOB) were measured in the treatment LPF-T. The treatments significantly affected the recovery rate of progressive motile sperm that presented the best value soon after thawing in the LPF-T treatment; moreover, the presence of trehalose, alone (LPF-T) or with sucrose (LPF-TS), significantly improved the recovery rate of progressive motile sperm also at T5 and T10 compared to LPF and LPF-S. The present results show a positive synergic action of DMA and trehalose on motile function of thawed chicken sperm. PMID- 27717657 TI - Explicit and implicit attitude toward an emerging food technology: The case of cultured meat. AB - Cultured meat is an unfamiliar emerging food technology that could provide a near endless supply of high quality protein with a relatively small ecological footprint. To understand consumer acceptance of cultured meat, this study investigated the influence of information provision on the explicit and implicit attitude toward cultured meat. Three experiments were conducted using a Solomon four-group design to rule out pretest sensitization effects. The first experiment (N = 190) showed that positive or negative information about cultured meat changed the explicit attitude in the direction of the information. This effect was smaller for participants who were more familiar with cultured meat. In the second experiment (N = 194) positive information was provided about solar panels, an attitude object belonging to the same sustainable product category as sustainable food products such as cultured meat. Positive information about solar panels was found to change the explicit attitude in the direction of the information. Using mood induction, the third experiment (N = 192) ruled out the alternative explanation that explicit attitude change in experiment 1 and 2 was caused by content free affect rather than category based inferences. The implicit attitude appeared insensitive to both information or mood state in all three experiments. These findings show that the explicit attitude toward cultured meat can be influenced by information about the sustainability of cultured meat and information about a positively perceived sustainable product. This effect was shown to be content based rather than merely affect based. Content based information in a relevant context could therefore contribute to the commercial success of cultured meat. PMID- 27717659 TI - Cross relaxation in nitroxide spin labels. AB - Cross relaxation, and mI-dependence of the intrinsic electron spin-lattice relaxation rate We, are incorporated explicitly into the rate equations for the electron-spin population differences that govern the saturation behaviour of 14N- and 15N-nitroxide spin labels. Both prove important in spin-label EPR and ELDOR, particularly for saturation recovery studies. Neither for saturation recovery, nor for CW-saturation EPR and CW-ELDOR, can cross relaxation be described simply by increasing the value of We, the intrinsic spin-lattice relaxation rate. Independence of the saturation recovery rates from the hyperfine line pumped or observed follows directly from solution of the rate equations including cross relaxation, even when the intrinsic spin-lattice relaxation rate We is mI dependent. PMID- 27717658 TI - German version of the Yale Food Addiction Scale 2.0: Prevalence and correlates of 'food addiction' in students and obese individuals. AB - The Yale Food Addiction Scale (YFAS) measures addiction-like eating of palatable foods based on the seven diagnostic criteria for substance dependence in the fourth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM IV). Most recently, a new version of the YFAS has been developed based on the revised eleven diagnostic criteria for substance use disorder in DSM-5. This YFAS 2.0 was translated into German and used among other measures in a study with 455 university students (89% female) and in a study with 138 obese patients presenting for bariatric surgery (78% female). In the student sample, the one factorial structure of the English version could be replicated and internal consistency was alpha = 0.90. The diagnostic threshold for 'food addiction' was met by 10% of the sample. 'Food addiction' diagnoses were associated with higher body mass, binge eating frequency, trait food craving, and attentional impulsivity as well as with lower perceived self-regulatory success in dieting. In the obese sample, the diagnostic threshold for 'food addiction' was met by 47% of participants. Again, 'food addiction' symptomatology was associated with higher binge eating frequency and attentional impulsivity. However, those with a 'food addiction' diagnosis did not differ from those without a diagnosis in body mass. To conclude, psychometric properties of the English YFAS 2.0 were replicated for the German YFAS 2.0. Prevalence rates and correlates of 'food addiction' as measured with the YFAS 2.0 were similar to those found with the previous version of the YFAS. Thus, the German YFAS 2.0 appears to be a reliable measure that can be used for the investigation of addiction-like eating behavior, analogous to the original version of the YFAS and the English YFAS 2.0.

AB - Most cases of candidiasis have been attributed to Candida albicans, but Candida glabrata, Candida parapsilosis and Candida tropicalis, designated as non-C. albicans Candida (NCAC), have been identified as frequent human pathogens. Moreover, Candida biofilms are an escalating clinical problem associated with significant rates of mortality. Biofilms have distinct developmental phases, including adhesion/colonisation, maturation and dispersal, controlled by complex regulatory networks. This review discusses recent advances regarding Candida species biofilm regulatory network genes, which are key components for candidiasis. PMID- 27717661 TI - Protective effect of quercetin on homocysteine-induced oxidative stress. AB - OBJECTIVE: The aim of this study was to evaluate whether quercetin (QUER) treatment could have a protective effect against oxidative stress induced by homocysteinemia in rats. MATERIALS AND METHODS: Thirty-two male Sprague-Dawley rats (adult) were assigned randomly to four groups: the control group was given physiological saline (PS; 1.5 mL/d); the QUER group was given QUER (50 mg/kg body weight [BW] daily) in distilled water and 0.25 mL PS; the homocysteine (HCY) group was given HCY (1 mg/kg BW daily) in distilled water and 1.25 mL PS; and the QUER + HCY group was given QUER 1 h before the administration of HCY. QUER, HCY, and PS were injected intraperitoneally every other day for 30 d. Plasma malondialdehyde (MDA), carbonyl, erythrocyte-reduced glutathione (GSH), plasma sulphydril (-SH) levels, erythrocyte catalase (CAT), and superoxide dismutase (SOD) activities were determined. RESULTS: Plasma CAT levels in the QUER group were found to be significantly higher than in the control group, whereas plasma MDA levels in the QUER group significantly decreased compared with the control group. In the HCY group, plasma MDA and carbonyl levels significantly increased and GSH and SOD levels significantly decreased compared with the control group. Plasma MDA levels significantly decreased and GSH and CAT levels significantly increased in the QUER + HCY group compared with the HCY group. Plasma -SH levels were significantly lower in the HCY group than in the control group. Plasma -SH levels were higher in the QUER + HCY group than in the HCY group, but they were not significant. CONCLUSION: The exposure of rats to HCY leads to oxidative stress reflected in increased MDA and decreased antioxidant enzyme levels. Administration of QUER might attenuate oxidative damage induced by HCY or have a protective effect against it. PMID- 27717662 TI - The most effective factors to offset sarcopenia and obesity in the older Korean: Physical activity, vitamin D, and protein intake. AB - OBJECTIVE: The aim of this study was to evaluate the effects of the types and levels of physical activity in conjunction with protein intake and vitamin D on sarcopenia and obesity status in an elderly population. METHODS: Study participants (N = 4452) were ages >=60 y and included 1929 men and 2523 women who completed a body composition analysis with a dual energy x-ray absorptiometry and provided health and dietary data. RESULTS: Higher appendicular skeletal muscle mass/weight was observed in the non-obese group, although obese participants had greater weights. The non-obese sarcopenia subgroup showed health problems related to insulin resistance and metabolic-related factors compared with the nonsarcopenic group. The total metabolic equivalent was significantly different in both obese categories, regardless of sarcopenic status. The prevalence of obesity, sarcopenia, and sarcopenic obesity relatively increased with a diet deficient of protein intake and vitamin D. CONCLUSION: These data suggest that sarcopenia had a significant association with metabolic-related factors; physical activity, especially vigorous activity; and protein intake and vitamin D levels in a non-obese elderly population. Therefore, maintaining healthy body weight by means of resistance exercise and enhanced protein intake and vitamin D may help offset sarcopenia in this age group. PMID- 27717663 TI - Fuzhuan tea reverses arterial stiffening after modest weight gain in mice. AB - OBJECTIVES: The aim of this study was to examine the effects of a Western diet (WD) and supplementation with Fuzhuan tea on large artery stiffness, as determined by aortic pulse wave velocity (aPWV). METHODS: Mice were subjected to a standard diet (SD; n = 12) or WD (n = 10) for 7 mo, and were then separated to receive nonsupplemented drinking water (SD-W and WD-W) or water supplemented with Fuzhuan tea (SD-T and WD-T) (200 mg/kg daily); mice were then maintained on their respective diets for an additional 2 mo. RESULTS: After the initial 7-mo feeding period, WD elicited a modest and significantly greater increase in body weight than did SD (39.6 +/- 0.71 versus 34.5 +/- 1.16 g; P < 0.01). PWV was significantly elevated in WD but not in SD (459.3 +/- 4.8 versus 422.4 +/- 6.4 cm/s; P < 0.001). Following an additional 2 mo, PWV continued to increase in WD W, but returned to control levels in WD-T (WD-W: 519.8 +/- 12.8; WD-T: 426.5 +/- 18.6; SD-W: 429.7 +/- 8.6; SD-T: 429.1 +/- 6.1 cm/s; P < 0.001, WD-W versus all groups). The increase in PWV in WD-W was accompanied by an increase in aortic collagen (WD-W: 38.8 +/- 4.6 versus SD-W: 17.5 +/- 5.1 percent cross-sectional area; P < 0.05). CONCLUSION: The results of the present study suggest that the increase in arterial stiffness after modest, diet-induced weight gain can be reversed by supplementation with Fuzhuan tea.

PMID- 27717665 TI - Type 2 innate lymphoid cell suppression by regulatory T cells attenuates airway hyperreactivity and requires inducible T-cell costimulator-inducible T-cell costimulator ligand interaction. AB - BACKGROUND: Atopic diseases, including asthma, exacerbate type 2 immune responses and involve a number of immune cell types, including regulatory T (Treg) cells and the emerging type 2 innate lymphoid cells (ILC2s). Although ILC2s are potent producers of type 2 cytokines, the regulation of ILC2 activation and function is not well understood. OBJECTIVE: In the present study, for the first time, we evaluate how Treg cells interact with pulmonary ILC2s and control their function. METHODS: ILC2s and Treg cells were evaluated by using in vitro suppression assays, cell-contact assays, and gene expression panels. Also, human ILC2s and Treg cells were adoptively transferred into NOD SCID gammaC-deficient mice, which were given isotype or anti-inducible T-cell costimulator ligand (ICOSL) antibodies and then challenged with IL-33 and assessed for airway hyperreactivity. RESULTS: We show that induced Treg cells, but not natural Treg cells, effectively suppress the production of the ILC2-driven proinflammatory cytokines IL-5 and IL-13 both in vitro and in vivo. Mechanistically, our data reveal the necessity of inducible T-cell costimulator (ICOS)-ICOS ligand cell contact for Treg cell-mediated ILC2 suppression alongside the suppressive cytokines TGF-beta and IL-10. Using a translational approach, we then demonstrate that human induced Treg cells suppress syngeneic human ILC2s through ICOSL to control airway inflammation in a humanized ILC2 mouse model. CONCLUSION: These findings suggest that peripheral expansion of induced Treg cells can serve as a promising therapeutic target against ILC2-dependent asthma.

PMID- 27717669 TI - The LGI1-ADAM22 protein complex in synaptic transmission and synaptic disorders. AB - Physiological functioning of the brain requires fine-tuned synaptic transmission, and its dysfunction causes various brain disorders such as autism, dementia, and epilepsy. It is therefore extremely important to identify and characterize key regulators of synaptic function. In particular, disease-related synaptic proteins, such as autism-related neurexin-neuroligin and psychiatric disorder related NMDA receptor, have attracted considerable attention. Recent basic and clinical research has highlighted critical roles of a ligand-receptor complex, LGI1-ADAM22, in synaptic transmission and brain function, as mutations in the LGI1 gene cause autosomal dominant lateral temporal lobe epilepsy and autoantibodies to LGI1 cause limbic encephalitis which is characterized by memory loss and seizures. Here, we will review our current knowledge about LGI1 and ADAM22, and discuss their patho-physiological roles in synaptic transmission and synaptic disorders. PMID- 27717667 TI - Global tobacco prevention and control in relation to a cardiovascular health promotion and disease prevention framework: A narrative review. AB - The purpose of this review is to emphasize the role of tobacco prevention and control in cardiovascular health (CVH) promotion and cardiovascular disease (CVD) prevention, including the importance of these endpoints for measuring the full impact of tobacco-related policies, programs, and practices. In this review, we describe an overview of tobacco control interventions that have led to substantial declines in tobacco use and the relationship between these declines with CVH and CVD. We review interventions that have had success in high-income countries (HICs) as well as those that are gaining traction in low- and middle income countries (LMICs). We emphasize the challenges to comprehensive tobacco prevention and control strategies faced by LMICs, and highlight the special role of cardiovascular health professionals in achieving CVH promotion and CVD prevention endpoints through tobacco control. Tobacco prevention and control strategies have a strong scientific basis, yet a distinct gap remains between this evidence and implementation of tobacco control policies, particularly in LMICs. Health professionals can contribute to tobacco control efforts, especially through patient-level clinical interventions, when supported by a health care system and government that recognize and support tobacco control as a critical strategy for CVH promotion and CVD prevention. Understanding, supporting, and applying current and evolving policies, programs, and practices in tobacco prevention and control is the province of all health professionals, especially those concerned with CVH promotion and CVD prevention. A new tobacco control roadmap from the World Heart Federation provides a strong impetus to the needed interdisciplinary collaboration. PMID- 27717670 TI - Formation and disruption of functional domains in myelinated CNS axons. AB - Communication in the central nervous system (CNS) occurs through initiation and propagation of action potentials at excitable domains along axons. Action potentials generated at the axon initial segment (AIS) are regenerated at nodes of Ranvier through the process of saltatory conduction. Proper formation and maintenance of the molecular structure at the AIS and nodes are required for sustaining conduction fidelity. In myelinated CNS axons, paranodal junctions between the axolemma and myelinating oligodendrocytes delineate nodes of Ranvier and regulate the distribution and localization of specialized functional elements, such as voltage-gated sodium channels and mitochondria. Disruption of excitable domains and altered distribution of functional elements in CNS axons is associated with demyelinating diseases such as multiple sclerosis, and is likely a mechanism common to other neurological disorders. This review will provide a brief overview of the molecular structure of the AIS and nodes of Ranvier, as well as the distribution of mitochondria in myelinated axons. In addition, this review highlights important structural and functional changes within myelinated CNS axons that are associated with neurological dysfunction.

Here, we explore emerging evidence suggesting that tuft cells are critical for protection during enteric infections and inflammatory responses. PMID- 27717672 TI - [Congenital "kissing" lesions: Nevus or "cafe au lait" spot?] AB - INTRODUCTION: "Cafe au lait" spots (CLS) are pigmented skin lesions principally located at the trunk and the limbs. Histologically, CLSs consist in an excessive pigmentation of the epidermis, with no risk of malignant transformation. The "kissing" nevus is a rare pigmented congenital nevus affecting both lower and upper eyelids in a mirror layout. As other nevi, it presents a theoretical risk of malignant transformation. These two pigmented lesions are responsible for aesthetic discomfort when affecting the face. OBSERVATION: Three patients presenting with a congenital pigmented lesion affecting the two eyelids in a mirror layout are presented. In two cases, the lesions, initially considered as "kissing" nevi, were classified as CLSs. The diagnosis of CLS was made on a biopsy in one patient and after surgery in the other one. DISCUSSION: Pigmented mirror layout lesions, called "kissing" lesions, are exclusively described for the nevi. We describe two cases of CLSs affecting the eyelids in a mirror layout. Difficulties in diagnostic are exposed and the possible treatments are discussed. PMID- 27717673 TI - Primary hydatid cyst of the neck: A rare and unusual site. AB - INTRODUCTION: Isolated parasitic swellings of the neck, particularly hydatid cysts, are rare, even in endemic countries. The aim of this study was to assess the epidemiological and clinical features and the diagnostic approach to head and neck hydatid disease. CASE REPORT: A 3-year-old boy was hospitalised for an isolated mass of the left side of the neck that had been gradually enlarging for one year. Neck ultrasound demonstrated a hypoechoic cystic structure on the lateral aspect of the neck, measuring 3.5cm in diameter. Histological examination of the surgical specimen confirmed the diagnosis of hydatid cyst. DISCUSSION: In endemic countries, a diagnosis of hydatid disease should be suspected in all cystic masses of the neck. Epidemiological, clinical, laboratory and radiological features can lead to a presumptive diagnosis of hydatid cyst and aspiration cytology can correct an erroneous diagnosis. Histological examination confirms the diagnosis in these unusual sites.

AB - Aquatic invasive species (AIS) pose major conservation challenges in freshwater ecosystems. In response, conservation organizations invest considerable resources in outreach to encourage AIS prevention behaviors among recreational boaters. Despite this, remarkably little is known about whether these efforts catalyze significant changes in boaters' perceptions, or whether they cause changes in behaviors that reduce AIS risk. We interviewed managers at the 14 Illinois organizations active in AIS outreach to determine regional priorities for, and investment in, AIS outreach. The results show a network of collaboration that reinforces a limited set of conservation messages. Next, we surveyed 515 recreational boaters to evaluate access to outreach, knowledge of AIS, and consistency of prevention behavior. Boater recognition of prevention slogans and knowledge of AIS and AIS prevention behavior was similar across Illinois regions despite large regional differences in investment in outreach. Most boaters (94%) report never intentionally moving organisms among waterbodies. Fewer reported that they Always perform recommended actions to reduce risk of AIS spread on their boat interior (68%), boat exterior (63%), or fishing tackle (47%). Recognition of prevention slogans and the number of AIS recognized were significantly, positively, associated with Always performing AIS prevention behavior on the vectors of the boat exterior, and fishing tackle, respectively. Our results suggest that increasing knowledge may be a necessary condition for higher adoption of AIS prevention behaviors, but that this alone may not be sufficient. Instead, efforts targeted at boaters who do not currently practice the recommended actions are likely to be necessary. PMID- 27717675 TI - Formaldehyde removal from wastewater and air by using UV, ferrate(VI) and UV/ferrate(VI). AB - Formaldehyde removal from an air stream absorbed into a water stream in a packed bed continuously and then removed by employing a combination of UV and ferrate(VI) as a highly-powerful oxidant in a continuous stirred tank. In addition, the removal of formaldehyde from water was investigated in both batch and continuous modes. The results of the study performed on formaldehyde contaminated water treatment can be used for both air and water treatment process design. The primary objective of this study is to compare the performance of using UV and ferrate(VI) individually with that of using UV/ferrate(VI) simultaneously to remove formaldehyde from both air and water. Moreover, the effects of several factors such as pH, ferrate(VI) concentration and temperature on formaldehyde removal from water using ferrate(VI) method were evaluated. The results of the current study in batch condition showed that the best initial pH and ferrate(VI) concentration to obtain the highest formaldehyde removal are 2 and 1 mg/l, respectively. The results of this part of research also reveal that temperatures rise from 25 degrees C to 50 degrees C increases formaldehyde removal from 69% to 97%; however, further increase in temperature has an adverse effect on removal efficiency. The combination of UV and ferrate(VI) enhances formaldehyde removal efficiency to very close to 100% within 35 min. In continuous air stream treatment, maximum formaldehyde removal of 94% was obtained by using a packed bed scrubber with gas over liquid flow rates ratio of 1.28 m3/m3. Although the results of this study shows that ferrate(VI) method for removal of formaldehyde can be considered as a promising alternative for both water and air treatment, further economic studies are required for this process to be commercialized. PMID- 27717676 TI - An enhanced approach for the use of satellite-derived leaf area index values in dry deposition modeling in the Athabasca oil sands region. AB - In the Athabasca oil sands region (AOSR) of Northern Alberta, the dry deposition of sulphur and nitrogen compounds represents a major fraction of total (wet plus dry) deposition due to oil sands emissions. The leaf area index (LAI) is a critical parameter that affects the dry deposition of these gaseous and particulate compounds to the surrounding boreal forest canopy. For this study, LAI values based on Moderate Resolution Imaging Spectroradiometer satellite imagery were obtained and compared to ground-based measurements, and two limitations with the satellite data were identified. The satellite LAI data firstly represents one-sided LAI values that do not account for the enhanced LAI associated with needle leaf geometry, and secondly, underestimates LAI in winter time northern latitude regions. An approach for adjusting satellite LAI values for different boreal forest cover types, as a function of time of year, was developed to produce more representative LAI values that can be used by air quality sulphur and nitrogen deposition models. The application of the approach increases the AOSR average LAI for January from 0.19 to 1.40, which represents an increase of 637%. Based on the application of the CALMET/CALPUFF model system, this increases the predicted regional average dry deposition of sulphur and nitrogen compounds for January by factors of 1.40 to 1.30, respectively. The corresponding AOSR average LAI for July increased from 2.8 to 4.0, which represents an increase of 43%. This increases the predicted regional average dry deposition of sulphur and nitrogen compounds for July by factors of 1.28 to 1.22, respectively. These findings reinforce the importance of the LAI metric for predicting the dry deposition of sulphur and nitrogen compounds. While satellite data can provide enhanced spatial and temporal resolution, adjustments are identified to overcome associated limitations. This work is considered to have application for other deposition model studies where dry deposition represents a significant fraction of total deposition. PMID- 27717677 TI - An efficient and economical treatment for batik textile wastewater containing high levels of silicate and organic pollutants using a sequential process of acidification, magnesium oxide, and palm shell-based activated carbon application. AB - Considering the chemical properties of batik effluents, an efficient and economical treatment process was established to treat batik wastewater containing not only high levels of Si and chemical oxygen demand (COD), but also toxic heavy metals. After mixing the effluents obtained from the boiling and soaking steps in the batik process, acidification using concentrated hydrochloric acid (conc. HCl) was conducted to polymerize the silicate under acidic conditions. Consequently, sludge was produced and floated. XRD and FT-IR analyses showed that wax molecules were coordinated by hydrogen bonding with silica (SiO2). The acidification process removed ~78-95% of COD and ~45-50% of Si, depending on the pH. In the next stage, magnesium oxide (MgO) was applied to remove heavy metals completely and almost 90% of the Si in the liquid phase. During this step, about 70% of COD was removed in the hydrogel that arose as a consequence of the crosslinking characteristics of the formed nano-composite, such as magnesium silicate or montmorillonite. The hydrogel was composed mainly of waxes with polymeric properties. Then, the remaining Si (~300 mg/L) in the wastewater combined with the effluents from the rinsing steps was further treated using 50 mg/L MgO. As a final step, palm-shell activated carbon (PSAC) was used to remove the remaining COD to < 50 mg/L at pH 3. Overall, the sequential process of acidification and MgO/PSAC application developed could serve as an economical and effective treatment option for treating heavily polluted batik effluents. PMID- 27717679 TI - Cancer heterogeneity and imaging. AB - There is interest in identifying and quantifying tumor heterogeneity at the genomic, tissue pathology and clinical imaging scales, as this may help better understand tumor biology and may yield useful biomarkers for guiding therapy based decision making. This review focuses on the role and value of using x-ray, CT, MRI and PET based imaging methods that identify, measure and map tumor heterogeneity. In particular we highlight the potential value of these techniques and the key challenges required to validate and qualify these biomarkers for clinical use. PMID- 27717678 TI - Results of application of the ISPD guidelines to the management of peritoneal dialysis in a single center in Sudan. AB - The culture negative peritonitis in Sudan 2010 was 46% exceeding 20% of the recommended ISPD (International Society for Peritoneal Dialysis) guidelines. This study reports an update after applying the standard ISPD protocol. The routine method was replaced by ISPD protocol. The culture negative rate using the ISPD guidelines dropped from 46% in the year 2010, to 39% in the year 2011, to 5% in the 2012 and to zero percent in the year 2013. Bacterial and fungal species represent (86.76%) and (13.23%) of infection and most isolates showed low resistance rate to antibiotics. Touch contamination added significantly (p=0.0006) to the risk of contracting Peritonitis. The risk of contracting Peritonitis was 1.53 times higher in the group exposed by touch contamination. None of the other risk factors contributed significantly to Peritonitis. The study highlights the importance of implementing high hygiene practice.

AB - OBJECTIVE: This study was performed to investigate whether the Penumbra 5MAX ACE is superior to other Penumbra systems. MATERIALS AND METHODS: We performed a retrospective, single center analysis of patients with acute ischemic stroke with occlusion of the internal carotid artery or middle cerebral artery (M1 segment) who underwent endovascular therapy using a Penumbra system. The reperfusion success rate, puncture-to-revascularization time, and number of passes were assessed. Multivariate regression analysis was conducted to evaluate independent factors related to revascularization within 60 minutes. Successful revascularization was defined by a thrombolysis in cerebral infarction score >=2b. RESULTS: The Penumbra 5MAX ACE was used in 24 of the 40 patients (60%). Although the revascularization success rate was similar between patient groups (P = .229), the number of passes was significantly lower (1.5 +/- .8 versus 2.6 +/- 1.3, P = .006) and the puncture-to-revascularization time was shorter (50 +/- 26 minutes versus 116 +/- 69 minutes, P = .002) in patients treated with the Penumbra 5MAX ACE. The Penumbra 5MAX ACE was identified as an independent factor for early revascularization (odds ratio, 5.80; P = .041). Among patients with a premorbid modified Rankin Scale score of 0-1, a modified Rankin Scale score of 0 2 at 3 months was observed in 15 of the 19 patients (79%) treated with the Penumbra 5MAX ACE and in 8 of the 16 (50%) who were not (P = .072). CONCLUSION: Acute revascularization therapy using the Penumbra 5MAX ACE can achieve rapid successful recanalization and tend to improve clinical outcomes. PMID- 27717682 TI - Exome Sequencing Identified CCER2 as a Novel Candidate Gene for Moyamoya Disease. AB - The etiology of Moyamoya disease (MMD) is still largely unclear, despite identification of RNF213 as the most significant susceptibility gene in East Asian patients. Following up our previous study confirming genetic heterogeneity in Japanese patients with MMD, we extensively surveyed novel candidate genes for a new perspective on the etiology of this disease. Two characteristic pedigrees without susceptibility variants in RNF213 were selected for whole-exome sequencing; 1 harbored 3 affected members, and the other included discordant monozygotic twins. In the former pedigree, 12 rare mutations in 12 genes were co segregated with MMD. One of the most deleterious amino acid changes among these was p.T76_G80delinsPS in CCER2, which was also mutated in the latter pedigree (p.E242K), although the unaffected twin sister shared the same mutation reflecting reduced penetrance. These CCER2 mutations were predicted to promote aggregation or oligomerization of their protein product, using in silico functional analysis. Subsequent CCER2 re-sequencing in an additional 135 MMD probands identified 1 recurrent and an additional 2 in-frame insertion-deletion mutations, recurrent p.T76_G80delinsPS, p.H218_H220del, and p.E299del. Although CCER2 molecular function is not well characterized, it is a secretory protein expressed in the brain; therefore, it constitutes a potential biomarker of MMD. PMID- 27717684 TI - Second pancreatectomy for recurrent pancreatic ductal adenocarcinoma in the remnant pancreas: A pooled analysis. AB - OBJECTIVES: The aim of this study was to examine the outcomes of second pancreatectomy for the treatment of recurrent pancreatic ductal adenocarcinoma (PDAC) in the remnant pancreas. METHOD: Search of the PubMed database was undertaken to identify relevant English language studies. Pooled individually data were examined for clinical outcomes after second pancreatectomy for recurrent PDAC. RESULTS: A total of 19 articles involving 55 patients were eligible for inclusion. The median disease-free interval after initial resection was 33 (range 7-143) months. Of the 55 patients reported, 52 (94.5%) patients underwent completion total pancreatectomy in the second operation for recurrences, including 15 patients who developed recurrences more than 5 years after the initial operation. There was no perioperative death. The 1-, 3- and 5 year overall survival rate after the second pancreatectomy was 82.2%, 49.2% and 40.6% respectively. CONCLUSION: Second pancreatectomy for recurrent PDAC can be performed safely with long-term survival in selected patients. PMID- 27717683 TI - Unattended Hospital and Home Sleep Apnea Testing Following Cerebrovascular Events. AB - BACKGROUND: Home sleep apnea testing (HSAT) is an alternative to polysomnography for the detection of obstructive sleep apnea (OSA). We assessed the feasibility of HSAT as an unattended screening tool for patients with a stroke or transient ischemic attack (TIA). AIMS: The primary outcome was the feasibility of unattended HSAT, as defined by analyzability of the data. Secondary outcomes included determining (1) predictors of obtaining nonanalyzable sleep data and (2) time to OSA detection and continuous positive airway pressure (CPAP) initiation. METHODS: In this single-center prospective observational study, inpatients or outpatients who had sustained a stroke or TIA were screened for OSA using the ApneaLink Plus ambulatory sleep monitor in their home or hospital room. RESULTS: There were 102 patients who completed unattended sleep monitoring. Mean age was 68.7 +/- 13.7 years, 55.9% were male, 57.8% were outpatients, and 77.5% had a stroke (22.5% with TIA). Eighty-two (80.4%) patients obtained four or more hours of analyzable sleep data. Functional dependence (defined as a modified Rankin Scale of >2) and elevated body mass index were independently associated with obtaining nonanalyzable data. OSA was detected in 63.4% (52 of 82) of patients and, of those, 34 of 52 (65.4%) initiated CPAP therapy. The mean time from study recruitment to HSAT was 1.7 days (median: 1, interquartile range [IQR]: 2) and CPAP was initiated on average within 62.7 days of recruitment (median: 53, IQR: 30). CONCLUSIONS: Unattended HSAT can be feasibly implemented after stroke or TIA. This method facilitates rapid diagnosis and management of OSA in both the outpatient and inpatient settings. PMID- 27717685 TI - A transgenic rat hepatocyte - Kupffer cell co-culture model for evaluation of direct and macrophage-related effect of poly(amidoamine) dendrimers. AB - Increasing number of papers demonstrate that Kupffer cells (KCs) play a role in the development of drug induced liver injury (DILI). Furthermore, elevated intracellular Ca2+ level of hepatocytes is considered as a common marker of DILI. Here we applied an in vitro model based on hepatocyte mono- and hepatocyte/KC co cultures (H/KC) isolated from transgenic rats stably expressing the GCaMP2 fluorescent Ca2+ sensor protein to investigate the effects of polycationic (G5), polyanionic (G4.5) and polyethylene-glycol coated neutral (G5 Peg) dendrimers known to accumulate in the liver, primarily in KCs. Following dendrimer exposure, hepatocyte homeostasis was measured by MTT cytotoxicity assay and by Ca2+ imaging, while hepatocyte functions were studied by CYP2B1/2 inducibility, and bilirubin and taurocholate transport. G5 was significantly more cytotoxic than G4.5 for hepatocytes and induced Ca2+ oscillation and sustained Ca2+ signals at 1MUM and10 MUM, respectively both in hepatocytes and KCs. Dendrimer-induced Ca2+ signals in hepatocytes were attenuated by macrophages. Activation of KCs by lipopolysaccharide and G5 decreased the inducibility of CYP2B1/2, which was restored by depleting the KCs with gadolinium-chloride and pentoxyphylline, suggesting a role of macrophages in the hindrance of CYP2B1/2 induction by G5 and lipopolysaccharide. In the H/KC, but not in the hepatocyte mono-culture, G5 reduced the canalicular efflux of bilirubin and stimulated the uptake and canalicular efflux of taurocholate. In conclusion, H/KC provides a good model for the prediction of hepatotoxic potential of drugs, especially of nanomaterials known to be trapped by macrophages, activation of which presumably contributes to DILI.

AB - Exposure to psychological stress is known to seriously disrupt the operation of the substantia nigra (SN) and may in fact initiate the loss of dopaminergic neurons within the SN. In this study, we aimed to investigate how chronic stress modified the SN in adult male mice. Using a paradigm of repeated restraint stress (an average of 20h per week for 6weeks), we examined changes within the SN using western blotting and immunohistochemistry. We demonstrated that chronic stress was associated with a clear loss of dopaminergic neurons within the SN. The loss of dopaminergic neurons was accompanied by higher levels of oxidative stress damage, indexed by levels of protein carbonylation and strong suppression of both microglial and astrocytic responses. In addition, we demonstrated for the first time, that chronic stress alone enhanced the aggregation of alpha-synuclein into the insoluble protein fraction. These results indicate that chronic stress triggered loss of dopaminergic neurons by increasing oxidative stress, suppressing glial neuroprotective functions and enhancing the aggregation of the neurotoxic protein, alpha-synuclein. Collectively, these results reinforce the negative effects of chronic stress on the viability of dopaminergic cells within the SN. PMID- 27717688 TI - Editorial Comment.

AB - Antibody-independent B cell functions play an important role in multiple sclerosis (MS) pathogenesis. In this study, B cell antigen presentation and costimulation in MS were studied. Peripheral blood B cells of MS patients showed increased expression of costimulatory CD86 and CD80 molecules compared with healthy controls (HC). In MS cerebrospinal fluid (CSF), 12-fold and 2-fold increases in CD86+ and CD80+ B cells, respectively, were evidenced compared with peripheral blood. Further, B cells from MS patients induced proinflammatory T cells in response to myelin basic protein (MBP). Immunomodulatory treatment restored B cell costimulatory molecule expression and caused significantly reduced B cell induced T cell responses. Together, these results demonstrate the potential of B cells from MS patients to induce autoreactive proinflammatory T cell responses. Immunomodulatory therapy abrogated this effect, emphasizing the importance of B cell antigen presentation and costimulation in MS pathology. PMID- 27717697 TI - Puerarin protects against cadmium-induced proximal tubular cell apoptosis by restoring mitochondrial function. AB - Puerarin (PU) is a potent free radical scavenger with a protective effect in nephrotoxin-mediated oxidative damage. Here, we show a novel molecular mechanism by which PU exerts its anti-apoptotic effects in cadmium (Cd)-exposed primary rat proximal tubular (rPT) cells. Morphological assessment and flow cytometric analysis revealed that PU significantly decreased Cd-induced apoptotic cell death of rPT cells. Administration of PU protected cells against Cd-induced depletion of mitochondrial membrane potential (DeltaPsim) and lipid peroxidation. Cd mediated mitochondrial permeability transition pore (MPTP) opening, disruption of mitochondrial ultrastructure, mitochondrial cytochrome c (cyt-c) release, caspase 3 activation and subsequently poly ADP-ribose polymerase (PARP) cleavage could be effectively blocked by the addition of PU. Moreover, up-regulation of Bcl-2 and down-regulation of Bax and hence increased Bcl-2/Bax ratio were observed with the PU administration. In addition, PU reversed Cd-induced ATP depletion by restoring DeltaPsim to affect ATP production and by regulating expression levels of ANT-1 and ANT-2 to improve ATP transport. In summary, PU inhibited Cd-induced apoptosis in rPT cells by ameliorating the mitochondrial dysfunction. PMID- 27717698 TI - Asparagus adscendens root extract enhances cognition and protects against scopolamine induced amnesia: An in-silico and in-vivo studies. AB - Asparagus adscendens Roxb. commonly known as safed musli and belonging to the Liliaceae family is cultivated mainly in Asian countries. In traditional medicine, safed musli is recommended as nerve tonic and remedy for memory impairment. The present study was aimed to evaluate nootropic and antiamnesic activities of Asparagus adscendens extract (AAE) using in silico and in vivo approach. Phytoconstituents of A. adscendens root reported in literature were subjected to in silico prediction using PASS and Pharmaexpert. The radial arm maze and passive shock avoidance paradigm were employed to evaluate nootropic activity. Subsequently, the anti-amnesic activity was evaluated in scopolamine induced amnesia model. To elucidate the mechanism of nootropic activity, the effect of AAE on the activities of acetylcholinesterase and antioxidant enzymes in the cortex and hippocampus of mice were also evaluated. In silico activity spectrum for all of A. adscendens phytoconstituents exhibited excellent prediction score for nootropic activity. Pretreatment with AAE (50, 100 & 200 mg/kg, i.p.) for 15 days showed significant decrease in working memory error, reference memory error and retrieval latency in radial arm maze and decrease in step down latency in passive shock avoidance paradigm were observed. Further, AAE significantly reduced acetylcholinesterase and oxidative stress parameters in cortex and hippocampus of mice. Thus, in silico and in vivo results suggest that A. adscendens root may exert its nootropic activity through both anti acetylcholinesterase and antioxidant activities. PMID- 27717699 TI - Chronic MeHg exposure modifies the histone H3K4me3 epigenetic landscape in Caenorhabditis elegans. AB - Methylmercury (MeHg) is a persistent environmental pollutant that occurs in the food chain, at occupational sites, and via medical procedures. Exposure in humans and animal models results in renal, neuro, and reproductive toxicities. In this study, we demonstrate that chronic exposure to MeHg (10MUM) causes epigenetic landscape modifications of histone H3K4 trimethylation (H3K4me3) marks in Caenorhabditis elegans using chromatin immuno-precipitation sequencing (ChIP seq). The modifications correspond to the locations of 1467 genes with enhanced and 508 genes with reduced signals. Among enhanced genes are those encoding glutathione-S-transferases, lipocalin-related protein and a cuticular collagen. ChIP-seq enhancement of these genes was confirmed with increased mRNA expression levels revealed by qRT-PCR. Furthermore, we observed enhancement of H3K4me3 marks in these genes in animals exposed to MeHg in utero and assayed at L4 stage. In utero exposure enhanced marks without alterations in mRNA expression except for the lpr-5 gene. Finally, knockdown of lipocalin-related protein gene lpr-5, which is involved in intercellular signaling, and cuticular collagen gene dpy-7, structural component of the cuticle, by RNA interference (RNAi) resulted in increased lethality of animals after MeHg exposure. Our results provide new data on the epigenetic landscape changes elicited by MeHg exposure, as well as describe a unique model for studying in utero effects of heavy metals. Together, these findings may help to understand the toxicological effects of MeHg at the molecular level. PMID- 27717700 TI - Influence of temperature and reaction time on the conversion of polystyrene waste to pyrolysis liquid oil. AB - This paper aims to investigate the effect of temperature and reaction time on the yield and quality of liquid oil produced from a pyrolysis process. Polystyrene (PS) type plastic waste was used as a feedstock in a small pilot scale batch pyrolysis reactor. At 400 degrees C with a reaction time of 75min, the gas yield was 8% by mass, the char yield was 16% by mass, while the liquid oil yield was 76% by mass. Raising the temperature to 450 degrees C increased the gas production to 13% by mass, reduced the char production to 6.2% and increased the liquid oil yield to 80.8% by mass. The optimum temperature and reaction time was found to be 450 degrees C and 75min. The liquid oil at optimum conditions had a dynamic viscosity of 1.77mPas, kinematic viscosity of 1.92cSt, a density of 0.92g/cm3, a pour point of -60 degrees C, a freezing point of -64 degrees C, a flash point of 30.2 degrees C and a high heating value (HHV) of 41.6MJ/kg this is similar to conventional diesel. The gas chromatography with mass spectrophotometry (GC-MS) analysis showed that liquid oil contains mainly styrene (48%), toluene (26%) and ethyl-benzene (21%) compounds. PMID- 27717702 TI - Characterization of gaseous emissions and ashes from the combustion of furniture waste. AB - Gaseous emissions and ash obtained in the combustion of furniture waste have been studied, with particular emphasis on the emissions of hazardous pollutants, such as PCDD/Fs and dl-PCBS. Two different combustion procedures were carried out, one of them in a conventional residential stove (without an automatic control of combustion air and bad mixing of combustion gases with air), and the other in a laboratory-scale reactor (operating under substoichiometric conditions). Three different experiments were carried out in the residential stove, in which the gaseous emissions and ashes obtained were analysed. The fuel burnt out in two of the experiments was furniture wood waste and in one of the experiments, the fuel burnt out was briquettes composed of a mixture of furniture wood with 10wt.% of polyurethane foam. One of the purposes of these experiments was the evaluation of the possible inhibition effect of the higher nitrogen content on the formation of PCDD/Fs. Slight inhibition of the PCDD/F formation was found although, it is noteworthy that the lowest yield of PAHs, volatile and semi-volatile compounds were obtained in the combustion of these briquettes. In all experiments, the emission factors of polychlorinated dibenzo-p-dioxins and dibenzofurans and dioxin-like polychlorinated biphenyls (PCDD/Fs and dl-PCBs) were between 29 and 74ng WHO-TEQ/kg sample burnt, lower than that obtained by other authors in the burning of pine needles and cones. PCDD/Fs and dl-PCBs emissions from furniture wood waste combustion were also analysed in the laboratory scale reactor at 850 degrees C and the results were compared with the values obtained from the combustion of solid wood (untreated wood). The total equivalent toxicity obtained was 21.1ng WHO-TEQ/kg sample for combustion of furniture wood waste, which is low in comparison with those obtained for other waste combustion in similar conditions. In the laboratory scale reactor, PCDFs were the dominant compounds in the profiles of PCDD/Fs, by contrast, in the combustion in the residential stove, the majority compounds were PCDDs, due to the different operation conditions. PMID- 27717701 TI - Techno-economic evaluation of a tandem dry batch, garage-style digestion-compost process for remote work camp environments. AB - The extraction of natural resources often involves housing workers in remote work camps far from population centres. These camps are prevalent in northern Alberta where they house approximately 40,000 workers involved in oil sands processing. The central, full-service cafeterias at these camps produce a significant quantity of food and cardboard waste. Due to their remote nature, these camps face high waste disposal costs associated with trucking waste long distances to the landfill. In this study, we investigated the techno-economic feasibility of on-site treatment of food and cardboard waste in a tandem dry batch, garage-style anaerobic digestion-compost process in which the waste material is converted into renewable energy used to heat the camp water supply and a nutrient-rich soil amendment for local land reclamation projects. Dry batch digestion and windrow composting pilot trials were performed on a simulated work camp waste in order to assess technical performance. The quality of the final compost was found to meet regulatory standards. A complete mass balance was then developed for a facility treating 3000 tonnes food waste and 435 tonnes waste cardboard annually. An economic assessment of such a facility was performed and, depending on the level of capital support and recognition of carbon credits for landfill methane mitigation, would require waste disposal costs to be between $115 and $195 CAD per tonne to meet financial criteria for project selection in Alberta's oil and gas industry. PMID- 27717703 TI - Penetrating Keratoplasty Performed by Residents Compared With an Experienced Cornea Transplant Surgeon. AB - BACKGROUND: Reports on keratoplasty by residents are rare compared to those on cataract surgery. The aim of this study was to compare the results and surgery time of penetrating keratoplasty performed by residents and an experienced cornea surgeon. METHODS: The medical records and surgery videos of the first 5 penetrating keratoplasty procedures by 4 residents were reviewed and compared with those in 20 penetrating keratoplasty procedures by an experienced cornea surgeon. Patients underwent penetrating keratoplasty at the Department of Ophthalmology, Tokyo Dental College, Chiba, Japan. The main outcome measures are graft survival, best-corrected visual acuity, postoperative astigmatism, decreased rate of graft endothelial cell density, and details of surgery time. RESULTS: Graft survival, best-corrected visual acuity, and postoperative astigmatism were not significantly different between residents group and the experienced surgeon group. The average decrease of graft endothelial cell density owing to surgery in residents and the experienced surgeon were 19.0 +/- 17.5 and 18.5 +/- 12.1%, respectively (p = 0.27, Mann-Whitney U test). The average surgery time taken by residents was 66.9 +/- 18.1 minutes, and that by the experienced surgeon it was 28.2 +/- 7.9 minutes (p = 0.0071, Mann-Whitney U test). Residents required the most time for running suture technique. CONCLUSIONS: The results of keratoplasty by residents were similar with those done by the experienced surgeon. Surgery time was the only statistically significant difference (p = 0.0071), which did not influence surgical results. PMID- 27717704 TI - How Informative are the Plastic Surgery Residency Websites to Prospective Applicants? AB - OBJECTIVE: To evaluate the comprehensiveness of plastic surgery program websites. DESIGN: American Medical Association interactive database was accessed for the list of integrated plastic surgery programs, in June 2015. Since then, 67 plastic surgery program websites were accessed and searched for the presence or absence of 31 criteria, which were further grouped into 5 categories: First, program contact information; second, training and research; third, program setup; fourth, benefits and facilities; and fifth, information for applicants. Programs were categorized based on US census bureau designated regions, and number of residency positions available. One-way ANOVA test was used for comparison. RESULTS: Only 25% (17) program website had information available on more than two-thirds (21 or more of 31) of the criteria. The 3 least factors commonly available by program websites were: operative log (10%), contract (10%), and information on night float (25%). The 3 most commonly available factors included: coordinator information (92%), number of residents (92%), and comprehensive faculty list (88%). Less than 50% of the programs provided information regarding fellowship opportunities, active and previous research projects, and operative logs. There was no difference in amount of information on program websites when analyzed for program size or program geographic location. CONCLUSION: Programs should consider revising their websites to include aforementioned 31 criteria. This would make applicants and potential resident physicians better informed of the programs before the interview process such that they would be more likely to apply to only those programs that match their specific aspirations. PMID- 27717705 TI - Does the H Index Correlate With Academic Rank Among Full-Time Academic Craniofacial Surgeons? AB - OBJECTIVE: To assess the relationship between the H index and the academic rank among full-time academic craniofacial surgeons. DESIGN: This was a cross sectional study of full-time academic craniofacial surgeons. SETTING: Data were compiled and analyzed at the Department of Plastic and Reconstructive Surgery, Johns Hopkins Hospital. RESULTS: The study sample included 127 full-time academic craniofacial surgeons. Overall, 89% were men, the mean number of years since completion of training was 16.2 +/- 11.2 years. Most surgeons had a background in plastic and reconstructive surgery. Approximately 75% had completed formal fellowship training. The mean H index for the sample was 12.4 +/- 9.9. The H index was strongly correlated with academic rank (rs = 0.62, p < 0.001). In a multiple linear regression model, adjusting for multiple confounders/effect modifiers, including number of years since training and total number of publications, the H index was significantly associated with academic rank (coefficient = 0.33, p = 0.04). CONCLUSIONS: Among full-time academic craniofacial surgeons, the H index is strongly correlated with the academic rank. PMID- 27717706 TI - Changing the Learning Curve in Novice Laparoscopists: Incorporating Direct Visualization into the Simulation Training Program. AB - OBJECTIVE: A major challenge in laparoscopic surgery is the lack of depth perception. With the development and continued improvement of 3D video technology, the potential benefit of restoring 3D vision to laparoscopy has received substantial attention from the surgical community. Despite this, procedures conducted under 2D vision remain the standard of care, and trainees must become proficient in 2D laparoscopy. This study aims to determine whether incorporating 3D vision into a 2D laparoscopic simulation curriculum accelerates skill acquisition in novices. DESIGN: Postgraduate year-1 surgical specialty residents (n = 15) at the Schulich School of Medicine and Dentistry, at Western University were randomized into 1 of 2 groups. The control group practiced the Fundamentals of Laparoscopic Surgery peg-transfer task to proficiency exclusively under standard 2D laparoscopy conditions. The experimental group first practiced peg transfer under 3D direct visualization, with direct visualization of the working field. Upon reaching proficiency, this group underwent a perceptual switch, changing to standard 2D laparoscopy conditions, and once again trained to proficiency. RESULTS: Incorporating 3D direct visualization before training under standard 2D conditions significantly (p < 0.0.5) reduced the total training time to proficiency by 10.9 minutes or 32.4%. There was no difference in total number of repetitions to proficiency. Data were also used to generate learning curves for each respective training protocol. CONCLUSIONS: An adaptive learning approach, which incorporates 3D direct visualization into a 2D laparoscopic simulation curriculum, accelerates skill acquisition. This is in contrast to previous work, possibly owing to the proficiency-based methodology employed, and has implications for resource savings in surgical training. PMID- 27717707 TI - Evaluation of Procedural Simulation as a Training and Assessment Tool in General Surgery-Simulating a Laparoscopic Appendectomy. AB - BACKGROUND: Laparoscopic appendectomy is a commonly performed surgical procedure, but few training models have been described for it. We examined a virtual reality module for practising a laparoscopic appendectomy. METHODS: A prospective cohort study with the following 3 groups of surgeons (n = 45): novices (0 procedures), intermediates (10-50 procedures), and experienced (>100 procedures). After being introduced to the simulator and 1 familiarization attempt on the procedural module, the participants practiced the module 20 times. Movements, task time, and procedure-specific parameters were compared over time. RESULTS: The time and movement parameters were significantly different during the first attempt, and more experienced surgeons used fewer movements and less time than novices (p < 0.01), although only 2 parameters were significantly different between novices and intermediates. All 3 groups improved significantly over 20 attempts (p < 0.0001). The intraclass correlation coefficient varied between 0.55 and 0.68 and did not differ significantly between the 3 groups (p > 0.05). When comparing novices with experienced surgeons, novices had a higher risk of burn damage to cecum (odds ratio [OR] = 3.0 [95% CI: 1.3; 7.0] p = 0.03), pressure damage to appendix (OR = 3.1 [95% CI: 2.0; 4.9] p < 0.0001), and grasping of the appendix (OR = 2.9 [95% CI: 1.8; 4.7] p < 0.0001). The risk of causing a perforation was not significantly different among the different experience levels (OR = 1.9 [95% CI: 0.9; 3.8] p = 0.14). Only 3 out of 5 error parameters differed significantly when comparing novices and experienced surgeons. Similarly, when comparing intermediates and novices, it was only 2 of the parameters that differed. DISCUSSION: The simulator module for practising laparoscopic appendectomy may be useful as a training tool, but further development is required before it can be used for assessment purposes. Procedural simulation may demonstrate more variation for movement parameters, and future research should focus on developing better procedure-specific parameters. PMID- 27717708 TI - Effect of Home-Call on Otolaryngology Resident Education: A Pilot Study. AB - OBJECTIVE: To inform institutional policies regarding call encounters through an evaluation of the effect of home-call on academic experience and fatigue among surgical residents. This study conducted an assessment of the nature of resident call encounters premidnight and postmidnight and a comparative analysis of sleep deprivation and efficiency in residents during home-call and off call. DESIGN, SETTING, AND PARTICIPANTS: All Otolaryngology-Head and Neck Surgery residents (n = 9) at single Canadian institution were asked to establish the time and nature of call encounters during home-call. Residents completed the Stanford Sleepiness Scale precall and postcall to measure sleepiness and wore an Actigraph device to measure sleep efficiency to establish fatigue in the setting of home-call as compared with residents off call. Home-call and off call patterns were studied using a random computer-generated selection of days for participants in both study groups. Analysis was conducted from December 1, 2013 to December 30, 2014. RESULTS: Residents received on average 7 pages per night, of which 78.5% of pages were for nonurgent issues. On an average, change in sleep deprivation scores postcall was 3.0 points higher (95% CI: 2.48-3.57, p < 0.0001) in residents who were qualified for a postcall day compared with residents who did not qualify for a postcall day and residents off call according to the Stanford Sleepiness Scale. Postcall sleep deprivation was significantly associated with number of encounters managed after midnight, regardless of management through telephone or in-hospital (p = 0.01). The Actigraph device identified a significant decrease in sleep efficiency in residents who were qualified for a postcall day compared with residents off call (mean = -31.1; 95% CI: -38.9, -23.4; p < 0.001). CONCLUSIONS: This is the first study to evaluate surgical residents' home-call experience. We identified a high proportion of nonurgent encounters that residents managed on call and increased postcall fatigue associated with postmidnight telephone encounters. This study highlights the detrimental effects of frequent sleep interruptions because of encounters on call and suggests the need for institutional guidelines to help minimize these interruptions.

AB - In some patients, renal nerve denervation has been reported to be an effective treatment for essential hypertension. Considerable evidence suggests that afferent renal nerves (ARN) and sodium balance play important roles in the development and maintenance of high blood pressure. ARN are sensitive to sodium concentrations in the renal pelvis. To better understand the role of ARN, we infused isotonic or hypertonic NaCl (308 or 500mOsm) into the left renal pelvis of conscious rats for two 2hours while recording arterial pressure and heart rate. Subsequently, brain tissue was analyzed for immunohistochemical detection of the protein Fos, a marker for neuronal activation. Fos-immunoreactive neurons were identified in numerous sites in the forebrain and brainstem. These areas included the nucleus tractus solitarius (NTS), the lateral parabrachial nucleus, the paraventricular nucleus of the hypothalamus (PVH) and the supraoptic nucleus (SON). The most effective stimulus was 500mOsm NaCl. Activation of these sites was attenuated or prevented by administration of benzamil (1MUM) or amiloride (10MUM) into the renal pelvis concomitantly with hypertonic saline. In anesthetized rats, infusion of hypertonic saline but not isotonic saline into the renal pelvis elevated ARN activity and this increase was attenuated by simultaneous infusion of benzamil or amiloride. We propose that renal pelvic epithelial sodium channels (ENaCs) play a role in activation of ARN and, via central visceral afferent circuits, this system modulates fluid volume and peripheral blood pressure. These pathways may contribute to the development of hypertension.

AB - Transcriptional coactivator with PDZ-binding motif (TAZ) is a key transcriptional mediator of Hippo signaling that has been recently reported to mediate Wnt activated transcription and serve as a component to suppress canonical Wnt/beta catenin activity. The Bromodomain and Extra-terminal domain (BET) family of proteins can recognize the acetylated lysine chain on histones and plays a critical role in transcriptional regulation. However, the mechanisms underlying transcriptional repression by the BET bromodomain are poorly understood. Here, we found that BET bromodomain inhibition upregulated TAZ protein and its transcriptional output, independent of its well-established role as a mediator of Hippo and Wnt signaling. Additionally, JQ1, a synthetic BET inhibitor, suppressed Wnt/beta-catenin activity by upregulating TAZ. Although JQ1 upregulated TAZ, which is known to promote cell proliferation, it drastically suppressed the growth of colon cancer cells by inducing cell cycle arrest. Collectively, our study identified an unexpected transcriptional repression function of the BET bromodomain and a novel mechanism for TAZ upregulation.

PMID- 27717713 TI - Biophysical approaches promote advances in the understanding of von Willebrand factor processing and function. AB - The large multimeric plasma glycoprotein von Willebrand factor (VWF) is essential for primary hemostasis by recruiting platelets to sites of vascular injury. VWF multimers respond to elevated hydrodynamic forces by elongation, thereby increasing their adhesiveness to platelets. Thus, the activation of VWF is force induced, as is its inactivation. Due to these attributes, VWF is a highly interesting system from a biophysical point of view, and is well suited for investigation using biophysical approaches. Here, we give an overview on recent studies that predominantly employed biophysical methods to gain novel insights into multiple aspects of VWF: Electron microscopy was used to shed light on the domain structure of VWF and the mechanism of VWF secretion. High-resolution stochastic optical reconstruction microscopy, atomic force microscopy (AFM), microscale thermophoresis and fluorescence correlation spectroscopy allowed identification of protein disulfide isomerase isoform A1 as the VWF dimerizing enzyme and, together with molecular dynamics simulations, postulation of the dimerization mechanism. Advanced mass spectrometry led to detailed identification of the glycan structures carried by VWF. Microfluidics was used to illustrate the interplay of force and VWF function. Results from optical tweezers measurements explained mechanisms of the force-dependent functions of VWF's domains A1 and A2 and, together with thermodynamic approaches, increased our understanding of mutation-induced dysfunctions of platelet-binding. AFM-based force measurements and AFM imaging enabled exploration of intermonomer interactions and their dependence on pH and divalent cations. These advances would not have been possible by the use of biochemical methods alone and show the benefit of interdisciplinary research approaches. PMID- 27717715 TI - A mandibular swelling of long duration. PMID- 27717716 TI - Postoperative changes in mandibular position after mandibular setback surgery via the surgery-first approach in relation to the increase of vertical dimension and the amount of mandibular setback. AB - OBJECTIVES: This study aimed to compare preoperatively predicted rotational relapse with actual post-treatment mandibular position after mandibular setback surgery via the surgery-first approach and to evaluate the effect of the increase of vertical dimension (VD) on surgical occlusion and the amount of mandibular setback on postoperative mandibular positional changes. STUDY DESIGN: Twenty-nine patients who underwent bilateral sagittal split ramus osteotomy for mandibular prognathism were evaluated by using lateral cephalograms, which had been obtained preoperatively, immediately postoperatively, and immediately after debonding. Increase of VD on surgical occlusion was measured preoperatively. We estimated the mandibular forward movement resulting from the postoperative mandibular anticlockwise rotation during postoperative orthodontic treatment and compared it with the actual post-treatment mandibular position. RESULTS: The actual postoperative mandibular forward movement (2.1 mm) was significantly greater compared with the forward movement (1 mm) predicted preoperatively (P < .01). The postoperative mandibular forward movement was greater in the groups with greater VD increase (>1.5 mm) or greater mandibular setback (>10 mm), even though there was no statistically significant difference. CONCLUSIONS: These results suggest that additional postoperative relapse may occur with mandibular rotational relapse, and VD increase and the amount of mandibular setback may affect post treatment mandibular position in surgery-first orthodontic treatment. PMID- 27717710 TI - Dysregulation of histone methyltransferases in breast cancer - Opportunities for new targeted therapies? AB - Histone methyltransferases (HMTs) catalyze the methylation of lysine and arginine residues on histone tails and non-histone targets. These important post translational modifications are exquisitely regulated and affect chromatin compaction and transcriptional programs leading to diverse biological outcomes. There is accumulating evidence that genetic alterations of several HMTs impinge on oncogenic or tumor-suppressor functions and influence both cancer initiation and progression. HMTs therefore represent an opportunity for therapeutic targeting in those patients with tumors in which HMTs are dysregulated, to reverse the histone marks and transcriptional programs associated with aggressive tumor behavior. In this review, we describe the known histone methyltransferases and their emerging roles in breast cancer tumorigenesis. PMID- 27717717 TI - Overview of guidelines on breast screening: Why recommendations differ and what to do about it. AB - Updated guidelines on breast cancer screening have been published by several major organisations over the past five years. Recommendations vary regarding both age range, screening interval, and even on whether breast screening should be offered at all. The variation between recommendations reflects substantial differences in estimates of the major benefit (breast cancer mortality reduction) and the major harm (overdiagnosis). Estimates vary considerably among randomised trials, as well as observational studies: from no benefit to large reductions, and from no overdiagnosis to substantial levels. The estimates vary according to the methodology of the randomised trials, and the design of the observational studies. Guideline recommendations reflect the choice of evidence informing them. While there are well-developed tools to deal with randomised trials in guideline work, these are not always used, or they may not be followed as recommended. Further, results of trials performed decades ago may no longer be applicable. For observational studies, the framework for inclusion in guidelines is not similarly well-developed and there are methodological concerns specific to screening interventions, such as small effects in absolute terms. There is a need for agreement on a hierarchy of observational study designs to quantify the major benefit and harm of cancer screening. This review provides a summary of recent guidelines on breast cancer screening and their major strengths and weaknesses, as well as a short overview of the major strengths and limitations of observational study designs. There is a need for agreement on a hierarchy of observational study designs in this field. PMID- 27717718 TI - Ovarian steroid withdrawal results in GABAA receptor upregulation in the photoperiodic neuroendocrine pathways of the turkey hen. AB - The mechanism(s) underlying photorefractoriness in temperate zone seasonally breeding birds remains undetermined. Our recent findings reveal a link between the upregulation of GABAA receptors (GABAARs) in the premammillary nucleus (PMM) and the state of photorefractoriness. Gonadal steroid levels fluctuate during the breeding season; increasing after gonadal recrudescence and declining sharply once gonadal regression begins. Here, we examined the effect of gonadal steroid withdrawal on the expression of GABAARs in the turkey PMM. Exogenous ovarian steroids were administered and then withdrawn from turkey hens to mimic the decline of ovarian steroids levels at the end of a breeding season. The upregulation of GABAAR alpha3, alpha4, delta, pi, and gamma2-subunits was observed in the PMM of the steroid withdrawal group when compared to the non steroid treatment group. The level of tyrosine hydroxylase, photopigment melanopsin, and circadian clock genes in the PMM of the steroid withdrawal group resembled the levels observed in the natural photorefractory hens and were significantly lower than those of the short-day light stimulated group. A reduction in gonadotropin-releasing hormone-I mRNA expressed within the nucleus commissurae pallii was also observed in hens undergoing steroid withdrawal. These results suggest that the natural decline in circulating ovarian steroid levels may modulate the GABAergic system in the PMM through the upregulation of GABAA receptors. This, in turn, could diminish the reproductive neuroendocrine responses to light and favor a condition resembling the state of photorefractoriness. PMID- 27717719 TI - Favorable outcome of blood urea nitrogen/creatinine-based hydration therapy 3 months after acute ischemic stroke. AB - BACKGROUND: Dehydration is associated with acute ischemic stroke. However, the relationship between hydration therapy given during acute ischemic stroke and clinical outcomes remains unclear. AIMS: We determined whether hydration therapy in patients with a blood urea nitrogen/creatinine (BUN/Cr) ratio of at least 15 improved clinical outcome. METHODS: We conducted a nonblinded, phase II, single arm, prospective study of patients with acute ischemic stroke and BUN/Cr ratio of at least 15 with historical controls. The hydration group received intravenous bolus (300-500 mL) saline followed by maintenance saline infusion (40-80 mL/h for the first 72 hours), whereas the control group received maintenance saline infusion (40-60 mL/h for the first 24 hours and 0-60 mL/h for 24-72 hours after stroke). The study end point was the percentage of patients with a favorable outcome defined as modified Rankin scale score of 2 or lower at 3 months after stroke. RESULTS: A total of 237 patients were enrolled (hydration, n = 134; control, n = 103). The mean volume of saline infused within the first 72 hours was significantly larger (P < .001), and the rate of favorable outcome at 3 months after stroke was significantly higher (P = .016) in the hydration group than in the controls. Further analysis revealed that the difference was significant in the lacunar stroke subtype (P = .020) but not in the nonlacunar subtype. CONCLUSIONS: Blood urea nitrogen/Cr ratio-based saline hydration therapy in patients with acute ischemic stroke significantly increased the rate of favorable clinical outcome with functional independence at 3 months after stroke. PMID- 27717720 TI - The quantitative evaluation of intracranial pressure by optic nerve sheath diameter/eye diameter CT measurement. AB - BACKGROUND: The changes of the optic nerve sheath diameter (ONSD) have been used to assess changes of the intracranial pressure for 20 years. The aim of this research was to further quantify the technique of measuring the ONSD for this purpose. METHODS: Retrospective study of computed tomographic (CT) data of 1766 adult patients with intracranial hypotension (n=134) or hypertension (n=1632) were analyzed. The eyeball transverse diameter (ETD) and ONSD were obtained bilaterally, and the ONSD/ETD ratio was calculated. The ratio was used to calculate the normal ONSD for patients and to estimate the intracranial pressure of the patients before and after the onset of the pathology. Correlation analysis was performed with invasively measured intracranial pressure, the presence or absence of papilledema, sex, and age. RESULTS: In hypotension cases, the ONSD by CT was 3.4+/-0.7 mm (P=.03 against normative 4.4+/-0.8 mm). In cases with hypertension, the diameter was 6.9+/-1.3 (P=.02, with a cutoff value ?5.5 mm). The ONSD/ETD ratio was 0.29+/-0.04 against 0.19+/-0.02 in healthy adults (P=.01). CONCLUSION: The ONSD and the ONSD/ETD ratio can indicate low intracranial pressure, but quantification is impossible at intracranial pressure less than 13 mm Hg. In elevated intracranial pressure, the ONSD and the ratio provide readings that correspond to readings in millimeters of mercury. The ONSD method, reinforced with additional calculations, may help to indicate a raised intracranial pressure, evaluate its severity quantitatively, and establish quantitative goals for treatment of intracranial hypertension, but the limitations of the method are to be taken into account.

PMID- 27717722 TI - CT interpretations in multiply injured patients: comparison of emergency physicians and on-call radiologists. AB - OBJECTIVE: In this study, emergency physicians and on-call radiologists were compared regarding identification of fatal injuries on computed tomographic (CT) scans in patients with trauma. MATERIALS AND METHODS: Multiply injured patients who were older than 18 years and underwent CT scanning were included in the study. The CT scans were interpreted by the responsible emergency physician. At the same time, these images were also evaluated by the on-call radiologist. Final evaluation was done 1 week later by a radiology instructor who knew the clinical follow-up of the patient. RESULTS: The study included 156 patients. The mean age of the patients included in the study was found to be 41.6 years. Less than half (33.5%) of the patients were female and 86.5% were male. A total of 482 CT scans were performed in the patients. Regarding brain CTs, the concordance rate for emergency physicians was 98%, whereas it was 94% for on-call radiologists. Regarding thoracic CTs, the concordance rate for emergency physicians was 91%, whereas was 93% for on-call radiologists. There was a perfect concordance (kappa value > 0.75) for on-call radiologists and emergency physicians in terms of brain and thoracic CTs. Regarding abdominal-pelvic CTs, the concordance rate for emergency physicians was 97%, whereas it was 98% for on-call radiologists. Moderate concordance (kappa range = 0.40-0.75) was detected for emergency physicians in terms of identification of liver, spleen, kidney, and intra abdominal/retroperitoneal hemorrhages. There was a perfect concordance (kappa value > 0.75) for pelvic fractures. CONCLUSION: In this study, it was shown that emergency physicians were successful in identifying fatal injuries on trauma CT images after a short-term training on interpretation of trauma CTs. PMID- 27717723 TI - Assessment of IgE-mediated food allergies in children with atopic dermatitis. AB - BACKGROUND: Atopic dermatitis (AD) is an inflammatory disease of the skin, which is characterised by a chronic relapsing course. AIM: The aim of the study was to assign the prevalence of clinically active food allergies among a group of children between 3 months and 7 years of age, with AD. METHODS: Eighty-eight children with AD were screened for specific IgE antibodies to food proteins. All patients with AD and specific IgE antibodies to food proteins were subjected to Oral Food Challenges (OFCs) with the relevant foods. RESULTS: Food-sensitised patients with moderate levels of sIgE had clinically active food allergy to milk (39.28%) and egg (42.34%) on the basis of positive OFCs. High IgE and eosinophilia had a prevalence of almost 80% and 25%, regardless of concomitant food sensitisation and disease severity. CONCLUSIONS: In this study, clinically active food allergies were recognised in 26.13% of children with AD. Nevertheless, no association was confirmed between food sensitisation and AD severity. High IgE and peripheral eosinophilia have not been found more prevalent among children with severe AD nor among children with food sensitisation. Infants and younger children with AD should be screened for an underlying food allergy, regardless of disease severity. PMID- 27717724 TI - Comparison of various classifications for patients with common variable immunodeficiency (CVID) using measurement of B-cell subsets. AB - BACKGROUND: Common variable immunodeficiency (CVID) is a heterogeneous disease, characterised by hypogammaglobulinaemia leading to recurrent infections and various complications. The aim of this study was to classify CVID patients based on four known classifications (Paris, Freiburg, EUROclass, and B-cell patterns) by measurement of B-cell subsets and to assess the relation of each classification with clinical manifestations. METHODS: We measured all B-cell subsets as both absolute count and percentage in 30 CVID patients and 30 healthy individuals using four-colour flow cytometry. Moreover, we evaluated antibody responses to pneumococcal vaccine in patients. RESULTS: A significant reduction in percentage of terminal B-cell subsets (total, marginal zone-like, switched memory, IgM-only memory, total memory B-cells and plasmablast) and absolute count of all B-cell subsets along with a strong increase in CD21low B-cells has been observed in patients. Patients with splenomegaly and hepatomegaly clustered in group Ia, smB+21low and group 1 based on known classifications, and significantly tended to have a decreased transitional and marginal zone-like B-cells count, as well as an increase in CD21low B-cell counts. Patients with lymphadenopathy, bronchiectasis and allergy had a significant decrease in absolute count of total memory, switched memory and total B-cells, respectively. CONCLUSION: Classification of patients could provide useful information to guide clinicians in long-term follow-up of CVID patients. Our data demonstrate that it may be more accurate to use absolute counts of B-cell subpopulations in CVID patients because absolute counts of B-cell subsets are more associated with clinical manifestations compared with their percentage and also four known classifications. PMID- 27717725 TI - Airway tone dysfunction among pre-schoolers with positive asthma predictive index: A case-control study. AB - OBJECTIVE: To measure lung function by impulse oscillometry (IOS) and spirometry in recurrent wheezer pre-schoolers according to their asthma predictive index (API) condition. METHODS: We performed a case-control study enrolling all pre schoolers with recurrent wheezing episodes (>3 episodes confirmed by physician) who presented at a paediatric pulmonology clinic. The population was divided according to stringent API criteria into positive or negative. RESULTS: In the nine-month period, 109 pre-schoolers were enrolled. After excluding one patient (due to lung function technique problems) 108 pre-schoolers (56 males, age range from 24 to 72 months) completed the study; 50 belong to positive API and 58 to negative API group. There were no differences in demographics between groups. More use of ICS was found in those with positive API than with negative API (62% vs. 12%, respectively, p=0.001). No differences in basal lung function and post bronchodilator response to salbutamol (by IOS or spirometry) were found between positive and negative API pre-schoolers. However, those positive API pre schoolers with ICS had significantly higher central basal airway resistance (RA at 20Hz) and higher post-BD response (% change in FEF25-75 and in FEV0.5) than those positive API without ICS. CONCLUSION: Recurrent wheezer pre-schoolers with positive API and ICS used may have airway dysfunction. More studies are needed to confirm this finding. PMID- 27717726 TI - Association of interleukin-1 family gene polymorphisms with juvenile idiopathic arthritis in Iranian population. AB - BACKGROUND: Cytokines, including interleukin-1 (IL-1), seem to contribute towards the pathogenesis of juvenile idiopathic arthritis (JIA), so this study was designed to evaluate the associations of IL-1 gene cluster and IL-1 receptor (IL 1R) gene single nucleotide polymorphisms (SNPs) with JIA proneness in Iranian population. MATERIALS AND METHODS: Genomic DNA of 55 Iranian patients with JIA and 140 controls were extracted and typed for IL-1alpha gene at position -889, IL 1beta gene at positions -511 and +3962, IL-1R gene at position Pst-I 1970, and interleikin-1 receptor antagonist (IL-1Ra) gene at position Mspa-I 11100, using polymerase chain reaction with sequence-specific primers method, and compared between patients and controls. RESULTS: The CC genotype of IL-1Ra at Mspa-I 11100 position was found to be more frequent in patients with JIA compared to healthy individuals (P=0.03), although the CT genotype at the same position was significantly higher in the control group in comparison with patients with JIA (P=0.02). No significant differences were observed between the two groups of case and control for IL-1alpha (-889 C/T), IL-1beta (-511 C/T and +3962 C/T) and IL-1R (Pst-1 1970 C/T). CONCLUSION: The results of the present investigation suggest that certain IL-1Ra gene variants are associated with individuals' susceptibility to JIA. Nevertheless, further studies are required to establish the results of the current study. PMID- 27717727 TI - Efficacy of parthenolide on lung histopathology in a murine model of asthma. AB - BACKGROUND: Parthenolide is the active constituent of the plant 'Tanacetum parthenium' (Feverfew) which has been used for centuries as a folk remedy for inflammatory conditions. AIM OF THE STUDY: In this study we aimed to investigate the effects of parthenolide in a murine model of chronic asthma. MATERIALS AND METHODS: Thirty-five BALB/c mice were divided into five groups; I (control), II (placebo), III (dexamethasone), IV (parthenolide) and V (dexamethasone and parthenolide combination). Lung histology was evaluated after treatment with the study drugs. Levels of interleukin (IL)-4 and IL-5 were determined by ELISA. RESULTS: Histologic parameters except the number of mast and goblet cells improved in the parthenolide group when compared with placebo. All parameters except basal membrane thickness and number of mast cells were improved significantly better in the group receiving dexamethasone when compared with the parthenolide group. Improvement of most of the histologic parameters was similar in Groups III and V. Interleukin-4 levels were significantly reduced in the parthenolide group when compared to the placebo group. CONCLUSION: We demonstrated that parthenolide administration alleviated some of the pathological changes in asthma. But parthenolide alone is not efficient as dexamethasone therapy and the parthenolide and dexamethasone combination also did not add any beneficial effect to the dexamethasone treatment. PMID- 27717728 TI - Bergenin attenuates renal injury by reversing mitochondrial dysfunction in ethylene glycol induced hyperoxaluric rat model. AB - Bergenin, isolated from Bergenia ligulata is a potent antioxidant and antilithiatic agent. Present work was designed to establish the biochemical role of bergenin on mitochondrial dysfunction in the ethylene glycol induced hyperoxaluric rat model. Bergenin was administrated at a dose of 10mg/kg body wt i.p. from 14th day of establishing the 28 days hyperoxaluria rat model. alpha Tocopherol was given as positive control at a dose of 100mg/kg body wt i.p. Mitochondrial dysfunction was studied by evaluating the activities of respiratory chain complexes, mitochondrial membrane potential and reactive oxygen species. Histopathological analysis of the kidney tissue was done after Pizzolato staining. Also, expression of monocyte chemoattractant protein -1(MCP-1) and kidney injury marker protein (KIM-1) were studied and the levels of IL-1beta were evaluated in kidney tissue homogenate. Mitochondrial dysfunction during stone crystallization was evident by decreased activities of electron transport chain complexes I, II and IV and augmented mitochondrial oxidative stress in hyperoxaluric rats. Bergenin treatment significantly (P<0.05) restored the activities of these complexes. Moreover, it curtailed the lipid peroxidation and up regulated antioxidant levels, ameliorating the state of mitochondrial dysfunction. The protective role of bergenin was also reinforced by reducing IL 1beta production and expression of KIM-1 and MCP-1 in the renal tissue. The findings of the present study provide evidence that bergenin exerted protective effects in hyperoxaluria through mitochondrial protection that involves attenuation of oxidative stress. Hence, it presented itself as an effective remedy in combating urolithiasis.

AB - A novel 3-benzylquinazolin-4(3H)-one derivative Z32, namely 6,7-dimethoxy-3-(3 chloro-4-(4-fluorobenzyloxy)benzyl)quinazolin-4(3H)-one was synthesized. The vasorelaxant and antihypertensive effects of Z32 and its underlying mechanisms were investigated. The following methods were used. The isometric tension of artery ring segments was recorded using an in vitro myography system. Changes in the calcium influx in mesenteric arteries were surveyed using a real-time confocal microscopy. The arterial pressure of spontaneously hypertensive rats was measured in vivo using a non-invasive tail cuff blood pressure system. The results showed that Z32 can relax rat mesenteric arteries pre-constricted by KCl or phenylephrine in a concentration-dependent manner. The vasorelaxant effects were not affected by the removal of the endothelium, blockade of potassium channels by tetraethylammonium chloride, or inhibition of either guanylate cyclase by ODQ, nitric oxide synthase by l-NAME, or cyclooxygenase by indomethacin. In Ca2+-free conditions, Z32 did not affect the constriction evoked by caffeine, however, significantly reduced the constrictions induced (1) by phenylephrine, (2) by CaCl2 in either phenylephrine (in the presence of verapamil) or KCl stimulated arteries, (3) by extracellular Ca2+ restoration in thapsigargin-treated mesenteric arteries, and (4) by the activator of protein kinase C phorbol-12, 13-dibutyrate, and the inhibitor of protein tyrosine phosphatase sodium orthovanadate. Further, Z32 decreased the systolic and diastolic arterial pressure of spontaneously hypertensive rats in a dose dependent manner. In conclusion, Z32 lowers the arterial pressure and induces vasorelaxation through the inhibition of calcium flux, probably via a protein tyrosine phosphorylation-dependent way.

AB - This work discusses an application of titanium oxide (TiOx) thin films deposited using physical (reactive magnetron sputtering, RMS) and chemical (atomic layer deposition, ALD) vapour deposition methods as a functional coating for label-free optical biosensors. The films were applied as a coating for two types of sensors based on the localised surface plasmon resonance (LSPR) of gold nanoparticles deposited on a glass plate and on a long-period grating (LPG) induced in an optical fibre. Optical and structural properties of the TiOx thin films were investigated and discussed. It has been found that deposition method has a significant influence on optical properties and composition of the films, but negligible impact on TiOx surface silanization effectiveness. A higher content of oxygen with lower Ti content in the ALD films leads to the formation of layers with higher refractive index and slightly higher extinction coefficient than for the RMS TiOx. Moreover, application of the TiOx film independently on deposition method enables not only for tuning of the spectral response of the investigated biosensors, but also in case of LSPR for enhancing the ability for biofunctionalization, i.e., TiOx film mechanically protects the nanoparticles and induces change in the biofunctionalization procedure to the one typical for oxides. TiOx coated LSPR and LPG sensors with refractive index sensitivity of close to 30 and 3400nm/RIU, respectively, were investigated. The ability for molecular recognition was evaluated with the well-known complex formation between avidin and biotin as a model system. The shift in resonance wavelength reached 3 and 13.2nm in case of LSPR and LPG sensors, respectively. Any modification in TiOx properties resulting from the biofunctionalization process can be also clearly detected.

AB - Maternal hyperglycemia can result in defects in glucose metabolism and pancreatic beta-cell function in offspring. The purpose of this study was to evaluate the impact of maternal diabetes mellitus on pancreatic islets, muscle and adipose tissue of the offspring, with or without oral l-Arginine supplementation. The induction of diabetes was performed using streptozotocin (60mg/kg). Animals were studied at 3 months of age and treatment (sucrose or l-Arginine) was administered from weaning. We observed that l-Arg improved insulin sensitivity in the offspring of diabetic mothers (DA), reflected by higher insulin-induced phosphorylation of Akt in muscle and adipose tissue. Insulin resistance is associated with increased oxidative stress and the NADPH oxidase enzyme plays an important role. Our results showed that the augmented interaction of p47PHOX with gp91PHOX subunits of the enzyme in skeletal muscle tissue in the offspring of diabetic rats (DV) was abolished after l-Arg treatment in DA rats. Maternal diabetes caused alterations in the islet functionality of the offspring leading to increased insulin secretion at both low (2.8mM) and high (16.7mM) concentrations of glucose. l-Arg reverses this effect, suggesting that it may be an important modulator in the insulin secretory process. In addition it is possible that l-Arg exerts its effects directly onto essential molecules for the maintenance and survival of pancreatic islets, decreasing protein expression of p47PHOX while increasing Akt phosphorylation and PDX-1 expression. The mechanism by which l-Arg exerts its beneficial effects may involve nitric oxide bioavailability since treatment restored NO levels in the pancreas. PMID- 27717732 TI - Evidence that the endometrial microbiota has an effect on implantation success or failure. AB - BACKGROUND: Bacterial cells in the human body account for 1-3% of total body weight and are at least equal in number to human cells. Recent research has focused on understanding how the different bacterial communities in the body (eg, gut, respiratory, skin, and vaginal microbiomes) predispose to health and disease. The microbiota of the reproductive tract has been inferred from the vaginal bacterial communities, and the uterus has been classically considered a sterile cavity. However, while the vaginal microbiota has been investigated in depth, there is a paucity of consistent data regarding the existence of an endometrial microbiota and its possible impact in reproductive function. OBJECTIVE: This study sought to test the existence of an endometrial microbiota that differs from that in the vagina, assess its hormonal regulation, and analyze the impact of the endometrial microbial community on reproductive outcome in infertile patients undergoing in vitro fertilization. STUDY DESIGN: To identify the existence of an endometrial microbiota, paired samples of endometrial fluid and vaginal aspirates were obtained simultaneously from 13 fertile women in prereceptive and receptive phases within the same menstrual cycle (total samples analyzed n = 52). To investigate the hormonal regulation of the endometrial microbiota during the acquisition of endometrial receptivity, endometrial fluid was collected at prereceptive and receptive phases within the same cycle from 22 fertile women (n = 44). Finally, the reproductive impact of an altered endometrial microbiota in endometrial fluid was assessed by implantation, ongoing pregnancy, and live birth rates in 35 infertile patients undergoing in vitro fertilization (total samples n = 41) with a receptive endometrium diagnosed using the endometrial receptivity array. Genomic DNA was obtained either from endometrial fluid or vaginal aspirate and sequenced by 454 pyrosequencing of the V3-V5 region of the 16S ribosomal RNA (rRNA) gene; the resulting sequences were taxonomically assigned using QIIME. Data analysis was performed using R packages. The chi2 test, Student t test, and analysis of variance were used for statistical analyses. RESULTS: When bacterial communities from paired endometrial fluid and vaginal aspirate samples within the same subjects were interrogated, different bacterial communities were detected between the uterine cavity and the vagina of some subjects. Based on its composition, the microbiota in the endometrial fluid, comprising up to 191 operational taxonomic units, was defined as a Lactobacillus dominated microbiota (>90% Lactobacillus spp.) or a non-Lactobacillus-dominated microbiota (<90% Lactobacillus spp. with >10% of other bacteria). Although the endometrial microbiota was not hormonally regulated during the acquisition of endometrial receptivity, the presence of a non-Lactobacillus-dominated microbiota in a receptive endometrium was associated with significant decreases in implantation [60.7% vs 23.1% (P = .02)], pregnancy [70.6% vs 33.3% (P = .03)], ongoing pregnancy [58.8% vs 13.3% (P = .02)], and live birth [58.8% vs 6.7% (P = .002)] rates. CONCLUSION: Our results demonstrate the existence of an endometrial microbiota that is highly stable during the acquisition of endometrial receptivity. However, pathological modification of its profile is associated with poor reproductive outcomes for in vitro fertilization patients. This finding adds a novel microbiological dimension to the reproductive process. PMID- 27717734 TI - [Continent cutaneous urinary diversion after cystectomy for cancer: A reliable alternative? A monocentric retrospective study]. AB - INTRODUCTION: Among available urinary diversion, continent cutaneous urinary diversion (CCUD) is not frequently used after cystectomy for malignancy. The aim of our work was to assess mid-term oncological and functional outcomes of CCUD in case of malignancies. PATIENTS AND METHODS: We retrospectively included all patients who underwent CCUD after radical cystectomy for cancer (according Mitrofanoff or Monti's principle) between July 2001 and November 2015 in our department. Perioperative data, oncological and functional outcomes were reported. To measure disease specific quality of life, we used the French version of Bladder Cancer Index. RESULTS: Overall 12 patients were involved in the study. With a median follow-up of 32 months, we noticed one death due to cancer recurrence. Early postoperative complications occurred in 8 patients, with one requiring reoperation. The late postoperative complication rate was 66%, whose 4 patients (33%) presented cutaneous stenosis. Overall satisfaction rate was scored 8.9/10 and body image was preserved for 75% of patients. At last follow-up, continence (no urinary leakage) was achieved for 62.5% of patient. Sexual impairment was significant for 5 patients. CONCLUSION: The CCUD is a valid alternative to other urinary diversions with similar oncological results and with a similar rate of complications. The high satisfaction rate was related to the preservation of body image and the high rate of continence. LEVEL OF EVIDENCE: 5. PMID- 27717733 TI - Novel mechanisms and approaches to overcome multidrug resistance in the treatment of ovarian cancer. AB - Ovarian cancer remains the leading cause of gynecological cancer-related mortality despite the advances in surgical techniques and chemotherapy drugs over the past three decades. Multidrug resistance (MDR) to chemotherapy is the major cause of treatment failure. Previous research has focused mainly on strategies to reverse MDR by targeting the MDR1 gene encoded P-glycoprotein (Pgp) with small molecular compound inhibitors. However, prior Pgp inhibitors have shown very limited clinical success because these agents have relatively low potency and high toxicity. Therefore, identification of more specific and potent new inhibitors would be useful. In addition, emerging evidence suggests that cancer stem cells (CSCs), deregulated non-coding RNA (ncRNA), autophagy, and tumor heterogeneity also contribute significantly to drug sensitivity/resistance in ovarian cancer. This review summarizes these novel mechanisms of MDR and evaluates several new concepts to overcome MDR in the treatment of ovarian cancer. These new strategies include overcoming MDR with more potent and specific Pgp inhibitors, targeting CSCs and ncRNA, modulating autophagy signaling pathway, and targeting tumor heterogeneity.

AB - OBJECTIVES: Report the reasons that lead families to refuse organ donation during their close solicitation by hospital coordination. MATERIAL AND METHODS: A retrospective study was conducted between 2012 and 2015, including 148 (34%) refusal of organ donation among 426 patients identified in a state of brain death. A questionnaire of the family was completed for each interview. Collected data concerned patient characteristics, cause of death, description of the interview and reasons for refusal. A descriptive statistical analysis was performed. RESULTS: The median age of patients was 50 years with a sex ratio of 1.4 men to 1 woman. The most common reason for non-donor family was the desire to maintain the integrity of the body of the patient (28%) followed by a religious order pattern (11%), brutality and suddenness of death (9%), the denial of death (6%) and early age of the donor (5%). In 39% of cases, the family said that the donor had expressed a written or oral refusal in his lifetime. CONCLUSION: A better understanding of the reasons leading to the refusal of non-donor family could provide assistance to the medical team on actions to general public with the aim to reduce the refusal rate. LEVEL OF EVIDENCE: 4. PMID- 27717737 TI - [Hospitalization rate in relation to severe complications of transrectal prostate biopsy: About 2715 patients biopsied]. AB - MAIN OBJECTIVE: To identify hospitalizations directly related to a complication occurring within 30 days following a transrectal prostate biopsy (PBP). SECONDARY OBJECTIVES: Overall hospitalization rates, mortality rates, potential predisposing factors for complications. PATIENTS AND METHODS: Single-center study including all patients who underwent PBP between January 2005 and January 2012. Any hospitalization occurring within 30 days of the PBP for urgent motive was considered potentially attributable to biopsy. We identified the reason for hospitalization with direct complications (urinary infection or fever, rectal bleeding, bladder caillotage, retention) and indirect (underlying comorbidities decompensation) of the biopsy. The contributing factors were anticoagulant or antiplatelet treatment well as waning immunity factors (corticosteroid therapy, HIV, chemotherapy or immunodulateur). RESULTS: Among 2715 men who underwent PBP, there were 120 (4.4%) hospitalizations including 28 (1.03%) caused by the biopsy. Twenty-five (0.92%) were related to a direct complication of biopsy: 14 (56%) for urinary tract infection or fever including 1 hospitalization in intensive care, 5 (20%) for rectal bleeding which required several transfusions 1, 10 (40%) urinary retention and 3 (0.11%) for an indirect complication (2 coronary syndromes and 1 respiratory failure). Several direct complications were associated in 3 cases. Only two hospitalizations associated with rectal bleeding were taking an antiplatelet or anticoagulant. There was no association between hospitalization for urinary tract infections and a decreased immune status. The first death observed in our study occurred at D31 of pulmonary embolism (advanced metastatic patient with bladder cancer). Twenty (60.6%) patients urgently hospitalized did not have prostate cancer. CONCLUSIONS: Within this large sample of patients the overall rate of hospitalization due to the realization of a PBP was 1%. It has not been found predictive of complications leading to hospitalization. LEVEL OF EVIDENCE: 4. PMID- 27717738 TI - Influence of Relative Strength on Functional Independence of Patients With Spinal Cord Injury. AB - OBJECTIVE: To investigate the influence of strength values and fat mass on functional independence of men with different spinal cord injury (SCI) levels. DESIGN: Cross-sectional study. SETTING: Hospital network. PARTICIPANTS: Men with SCI (N=45). INTERVENTIONS: Subjects were assessed in functional independence scales, a 1 repetition maximum (1RM) test, and body composition to detect absolute and relative strength: 1RM divided by body mass (BM) and lean body mass (LBM), respectively. MAIN OUTCOME MEASURES: Stepwise multiple regression analysis was used to verify the influence of predictors on functional independence (FIM and Spinal Cord Independence Measure [SCIM] scale and subscales). Receiver operating characteristic curves were created to identify cutoff points of strength for functional independence. RESULTS: The best models for FIM total, FIM mobility, and SCIM total used 1RM as the best predictor (adjusted R2=.75, .67, and .65, respectively; P<.05). Relative strength (1RM/LBM) was the best predictor for SCIM mobility (adjusted R2=.62, P<.05). A FIM score of 69 has a 1RM cutoff point of 50.1kg, and a FIM score of 76 has cutoff points of .73 for 1RM/BM and .91 for 1RM/LBM. A SCIM score of 68 has cutoff points for 1RM, 1RM/BM, and 1RM/LBM of 50.1kg, .77, and .92, respectively. CONCLUSIONS: Cutoff points of relative strength should be used as determinant variables for independence, health, or sports performance. This study may contribute to more adequate guidance of physical activity during a rehabilitation program and after discharge. PMID- 27717739 TI - How Myosin Generates Force on Actin Filaments. AB - How myosin interacts with actin to generate force is a subject of considerable controversy. The major debate centers on understanding at what point in force generation the inorganic phosphate is released with respect to the lever arm swing, or powerstroke. Resolving the controversy is essential for understanding how force is produced as well as the mechanisms underlying disease-causing mutations in myosin. Recent structural insights into the powerstroke have come from a high-resolution structure of myosin in a previously unseen state and from an electron cryomicroscopy (cryo-EM) 3D reconstruction of the actin-myosin-MgADP complex. Here, we argue that seemingly contradictory data from time-resolved fluorescence resonance energy transfer (FRET) studies can be reconciled, and we put forward a model for myosin force generation on actin. PMID- 27717741 TI - Comparison of three commercial dosimetric systems in detecting clinically significant VMAT delivery errors. AB - AIM: To study the sensitivity of three commercial dosimetric systems, Delta4, Multicube and Octavius4D, in detecting Volumetric Modulated Arc Therapy (VMAT) delivery errors. METHODS: Fourteen prostate and head and neck (H&N) VMAT plans were considered for this study. Three types of errors were introduced into the original plans: gantry angle independent and dependent MLC errors, and gantry angle dependent dose errors. The dose matrix measured by each detector system for the no-error and error introduced delivery were compared with the reference Treatment Planning System (TPS) calculated dose matrix for no-error plans using gamma (gamma) analysis with 2%/2mm tolerance criteria. The ability of the detector system in identifying the minimum error in each scenario was assessed by analysing the gamma pass rates of no error delivery and error delivery using a Wilcoxon signed-rank test. The relative sensitivity of the system was assessed by determining the slope of the gamma pass line for studied error magnitude in each error scenario. RESULTS: In the gantry angle independent and dependent MLC error scenario the Delta4, Multicube and Octavius4D systems detected a minimum 2mm error. In the gantry angle dependent dose error scenario all studied systems detected a minimum 3% and 2% error in prostate and H&N plans respectively. In the studied detector systems Multicube showed relatively less sensitivity to the errors in the majority of error scenarios. CONCLUSION: The studied systems identified the same magnitude of minimum errors in all considered error scenarios. PMID- 27717740 TI - Antimicrobial growth promoter use in livestock: a requirement to understand their modes of action to develop effective alternatives. AB - Antimicrobial agents (AMAs) have been used in agriculture since the 1950s as growth-promoting agents [antimicrobial growth promoters (AGPs)]. They have provided benefits to the agricultural industry by increasing production efficiencies and maximising livestock health, yet the potential risks surrounding resistance to AMAs in medically important pathogenic bacteria have enhanced public and government scrutiny regarding AMA use in agriculture. Although it is recognised that AGP administration can select for resistance to AMAs in enteric bacteria of livestock, conclusive evidence showing a link between resistant bacteria from livestock and human health is lacking (e.g. transmission of resistant zoonotic pathogens). Livestock production output must be increased significantly due to the increase in global population, and thus the identification of non-AMA alternatives to AGP use is required. One strategy employed to identify alternatives to AGPs is an observational empirical methodology, but this approach has failed to deliver effective alternatives. A second approach is aimed at understanding the mechanisms involved in AGP function and developing alternatives that mimic the physiological responses to AGPs. New evidence indicates that AGP function is more complex than merely affecting enteric bacterial populations, and AGPs likely function by directly or indirectly modulating host responses such as the immune system. As such, a more comprehensive understanding of the mechanisms associated with AMA function as AGPs will facilitate the development of effective alternatives. PMID- 27717742 TI - Effect of intraocular pressure (IOP) and choroidal circulation on controlled episcleral drug delivery to retina/vitreous. AB - Transscleral drug delivery may become a safe alternative to the intravitreal injection for chronic retinal diseases such as age-related macular degeneration or diabetic macular edema. However, the drug delivered onto the sclera subjects to vigorous clearance by episcleral and choroidal circulation; in addition, the penetration from episclera to retina needs to overcome counter-directional ocular fluid current driven by intraocular pressure (IOP) as well as unfavorable drug disposition exerted by drug transporters before the drug reach retina. It is imperative to understand these processes and quantitate their influence for efficient designing of a sustained formulation or device to achieve efficient transscleral drug delivery. The current study was focused on the effects of intraocular pressure (IOP) and choroidal circulation on transscleral drug delivery using triamcinolone acetonide (TA) as a model drug. Rabbit eye IOP was modulated through cannulation in ex vivo study or through cryopexy of ciliary body in vivo studies before subtenon TA injection or episcleral TA-film implantation. In a subgroup of the rabbit eyes, localized choroid atrophy was induced by cryopexy before TA-film implantation. Each condition had a concurrent control group. The vitreous TA concentration was quantitated by ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC/MS/MS). The vitreous TA concentration was compared between the study and control groups for effect of IOP or choroid circulation. For ex vivo studies, higher IOP was a significant effect against TA penetration from episclera towards vitreous. TA was 8.5+/-5ng/mL in receptor chamber with a cross pressure of 50mmHg versus 15.9+/ 10ng/mL with the cross pressure of 5mmHg; p=0.001, t-test. A multivariate regression demonstrated each mmHg of IOP increase would result in 3ng/mL lower concentration in the receptor chamber. Similar IOP effect was also identified in a 3-hour study using euthanized rabbit eyes whose IOP was controlled at 10 or 40mmHg by cannulation (3261+/-1821ng/mL vs. 755+/-763ng/mL; p=0.013, Wilcoxon test). However, the effect of IOP was not significant in alive animal with the same IOP setting. In vivo chronic study using low IOP (7.7mmHg) versus normal IOP (14.4mmHg), vitreous TA was not statistically significant (154+/-200ng/mL vs. 80+/-130ng/mL, p=0.17, Wilcoxon test). However, removing of choroidal circulation by local cryopexy significantly enhanced the TA penetration from episclera to vitreous (mean 163+/-129.8ng/mL for choroidal cryopexy vs. 81.8+/-37.2ng/mL for ciliary cryopexy or 75.5+/-36ng/mL for control group, p=0.007, regression analysis). In conclusion, the effect of IOP on transscleral drug delivery was not a significant effect in alive rabbit eyes; however, choroidal circulation seems to be a significant effect to affect TA penetration from episclera towards retina and vitreous. PMID- 27717744 TI - Sex steroids effects on guinea pig airway smooth muscle tone and intracellular Ca2+ basal levels. AB - : Testosterone (TES), other androgens and female sex steroids induce non-genomic rapid relaxing effects in airway smooth muscle (ASM). In guinea pig ASM, basal tension was relaxed by dehydroepiandrosterone (DHEA) and TES; 17beta-estradiol (E2) had a small effect. Blockers of L-type voltage dependent Ca2+ channel (L VDCC, D-600) and store operated Ca2+ channel (SOC, 2-APB) also relaxed the basal tone. In tracheal myocytes, DHEA and TES diminished intracellular basal Ca2+ concentrations (b[Ca2+]i) as D-600+2-APB but to a higher extend. TES after D 600+2APB or Pyr3, a blocker of canonical transient receptor potential 3 (TRPC3), further decreased b[Ca2+]i rendering this response equal to TES alone. With indomethacin, the b[Ca2+]i decrease induced by the blockade of L-VDCC and TRPC3 was not changed by the addition of TES. PGE2 or forskolin addition after D600+2 APB, decreased b[Ca2+]i resembling TES response. An adenylate cyclase inhibitor followed by D-600+2-APB lowered b[Ca2+]i, TES showed no further effect. Carbachol induced [Ca2+]i increment was reduced by TES or DHEA. 17beta-estradiol diminished KCl-induced contraction and, in tracheal myocytes, the voltage-dependent inward Ca2+ current. CONCLUSION: DHEA and TES diminish ASM tone and b[Ca2+]i by blocking L-VDCC and probably a constitutively active TRPC3, and by PGE2 synthesis. E2 lowers ASM basal tone by blocking only L-VDCC. PMID- 27717743 TI - AKT1 has dual actions on the glucocorticoid receptor by cooperating with 14-3-3. AB - Glucocorticoids are important therapeutic compounds for acute lymphoblastic leukemia (ALL). AKT1 or the protein kinase B is frequently activated in ALL, and contributes to the development of glucocorticoid resistance. We examined impact of AKT1 on glucocorticoid receptor (GR)-induced transcriptional activity in cooperation with phospho-serine/threonine-binding protein 14-3-3. AKT1 has two distinct actions on GR transcriptional activity, one through segregation of GR in the cytoplasm by phosphorylating GR at Ser-134 and subsequent association of 14-3 3, and the other through direct modulation of GR transcriptional activity in the nucleus. For the latter, AKT1 and 14-3-3 are attracted to DNA-bound GR, accompanied by AKT1-dependent p300 phosphorylation, H3S10 phosphorylation and H3K14 acetylation at the DNA site. These two actions of AKT1 regulate distinct sets of glucocorticoid-responsive genes. Our results suggest that specific inhibition of the AKT1/14-3-3 activity on the cytoplasmic retention of GR may be a promising target for treating glucocorticoid resistance observed in ALL. PMID- 27717746 TI - Brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein-1 cooperates with glycogen synthase kinase-3beta to regulate osteogenesis of bone marrow mesenchymal stem cells in type 2 diabetes. AB - Type 2 diabetes mellitus (T2DM) is associated with inhibited osteogenesis of bone marrow mesenchymal stem cells (BMSCs). Brain and muscle ARNT-like protein 1 (BMAL1) has been linked to the T2DM-related bone remodeling, however, the specific mechanism is still unclear. Herein, we aimed to determine the role of BMAL1 in T2DM-induced suppression of BMSCs osteogenesis. Inhibited osteogenesis and BMAL1 expression were showed in diabetic BMSCs. And while beta-catenin and T cell factor (TCF) expression were decreased, the glycogen synthase kinase-3beta (GSK-3beta) and nemo-like kinase (NLK) expression were increased in diabetic BMSCs. Moreover, over-expression of BMAL1 led to recovered osteogenesis ability and activation of Wnt/beta-catenin pathway, which was partially due to inhibition of GSK-3beta caused by over-expression of BMAL1. Taken together, our findings provide new insights into the role of BMAL1 in T2DM-induced suppression of BMSCs osteogenesis. Over-expressed BMAL1 could recover BMSCs osteogenesis in T2DM partially by decreasing GSK-3beta expression to activate Wnt/beta-catenin pathway. BMAL1 may have a potential use in repairing diabetic bone metabolic disorders. PMID- 27717745 TI - Environmental estrogen-like endocrine disrupting chemicals and breast cancer. AB - BACKGROUND: Estrogen-mimicking endocrine disruptors (EEDs) such as polychlorinated biphenyls (PCBs), bisphenol A (BPA), and phthalates have been found ubiquitously throughout our environment. Although exposure to EEDs has the ability to interfere with endocrine control of reproductive function and development in both humans and wildlife, inconsistent reports have made it difficult to draw conclusions concerning the hypothesized increased risk of breast cancer associated with EEDs. OBJECTIVES: The purpose of this study was to examine the cross-sectional relationship between exposure to PCBs, BPA or phthalates; and risk of breast cancer in U.S. women using the Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey (NHANES) data between 1999 and 2004. METHODS: We analyzed data from female participants (20 years of age and older) collected by NHANES between 1999 and 2004 for exposure assessment based on lipid adjusted serum levels of 6 individual PCB congeners (PCB 074, 099, 118, 138, 153, and 180), the sum of dioxin-like PCBs (074 and 118), and the sum of non-dioxin-like PCBs (099 + 138 + 153 + 187). Levels of urinary BPA and seven phthalate metabolites mono-n-butyl phthalate (MnBP), mono-isobutyl phthalate (MiBP), mono-ethyl phthalate (MEP), mono-(3 caroxypropyl) phthalate (MCPP), mono-benzyl phthalate (MZP), and three metabolites of di (2-ehtylhexyl) phthalate (DEHP): [mono-2-ethylhexyl phthalate (MEHP), mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP), and mono-(2-ethyl-5 oxohexyl) phthalate (MEOHP)] were obtained from the 2003-2010 yearly survey cycles in participants aged 6 years and older. Assessments of EEDs or their metabolites were analyzed in conjunction with medical and reproductive health questionnaire data. Age, race/ethnicity, age at menarche, body mass index (BMI; kg/m2), and lactation were considered as potential confounders in our final models. Geometric means (GM) were calculated to compare PCB, BPA or phthalate concentrations in women who self-reported a breast cancer diagnosis versus women who self-reported never being diagnosed with breast cancer. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CI) for the association between PCB, BPA or phthalate measurements and breast cancer. RESULTS: In age, race/ethnicity, and BMI adjusted models, PCB138 was the only congener found to be significantly associated with breast cancer [OR of 3.16; 95% CI: 1.14-8.76]. We also found the sum of non-dioxin-like PCBs to be significantly associated with breast cancer [OR of 1.14; 95% CI: 1.00-1.29]. Risk of breast cancer, however, was not found to be significantly associated with phthalate, phthalate metabolites, and BPA in unadjusted or adjusted logistic regression models. CONCLUSIONS: Our results suggest a link between environmental exposures to PCB 138 and breast cancer. There were no significant associations between phthalates or BPA and breast cancers. These findings should be interpreted with caution because of the use of cross-sectional self-reported data and a small sample size of breast cancer subjects. Nonetheless, our finding emphasizes a need of comprehensive environmental molecular epidemiologic study to determine the potential role of environmental exposures to PCBs, phthalates, and BPA in the development of breast cancer. PMID- 27717747 TI - Lack of stability at more than 12 months of follow-up after anterior cruciate ligament reconstruction using all-inside quadruple-stranded semitendinosus graft with adjustable cortical button fixation in both femoral and tibial sides. AB - INTRODUCTION: The use of the semitendinosus tendon alone for anterior cruciate ligament reconstruction keeps the gracilis muscle intact and decreases anterior pain in comparison with the use of the patellar tendon. Recently, Lubowitz described a new all-inside technique with an ST4 tendon fixed with a cortical button in both femoral and tibial sides. We hypothesized that this type of graft with cortical button fixation provides well-controlled residual anterior tibial translation (<3mm). The aim of this study was to assess the results obtained with this technique in terms of laxity and IKDC score at more than 1 year of follow up. MATERIAL AND METHODS: We performed a prospective single-center study to evaluate the results with this procedure with at least 1 year of follow-up. The primary endpoint was the objective IKDC score and side-to-side anterior tibial translation difference. The secondary endpoint was the subjective assessment using the subjective IKDC and Lysholm scores. Tunnel positioning was assessed using the Aglietti criteria. RESULTS: Thirty-five patients were included and reviewed with a mean follow-up of 19.7 months. Sixty-three percent of the patients were male and the mean age at the procedure was 28 years. The IKDC score was A or B in 43% of the patients and C or D in 57%; 54% of the patients had a residual side-to-side anterior tibial translation difference less than 3mm and 29% presented significant pivot shift (grade C or D). Five patients underwent revision surgery, including one for rupture of the ACL reconstruction. The meniscal status did not influence postoperative laxity and the IKDC grade. DISCUSSION: Our hypothesis was not verified and the postoperative stability of the knee was insufficient. Postoperative side-to-side anterior tibial translation difference remained greater than 3mm for 16 patients and the analysis seems to indicate that the distal cortical fixation of the graft with an adjusted loop is insufficient. LEVEL OF EVIDENCE: Prospective study - Level IV. PMID- 27717748 TI - Whole genome sequencing and phylogenetic characterization of brown bullhead (Ameiurus nebulosus) origin ranavirus strains from independent disease outbreaks. AB - Ranaviruses are emerging pathogens associated with high mortality diseases in fish, amphibians and reptiles. Here we describe the whole genome sequence of two ranavirus isolates from brown bullhead (Ameiurus nebulosus) specimens collected in 2012 at two different locations in Hungary during independent mass mortality events. The two Hungarian isolates were highly similar to each other at the genome sequence level (99.9% nucleotide identity) and to a European sheatfish (Silurus glanis) origin ranavirus (ESV, 99.7%-99.9% nucleotide identity). The coding potential of the genomes of both Hungarian isolates, with 136 putative proteins, were shared with that of the ESV. The core genes commonly used in phylogenetic analysis of ranaviruses were not useful to differentiate the two brown bullhead ESV strains. However genome-wide distribution of point mutations and structural variations observed mainly in the non-coding regions of the genome suggested that the ranavirus disease outbreaks in Hungary were caused by different virus strains. At this moment, due to limited whole genome sequence data of ESV it is unclear whether these genomic changes are useful in molecular epidemiological monitoring of ranavirus disease outbreaks. Therefore, complete genome sequencing of further isolates will be needed to identify adequate genetic markers, if any, and demonstrate their utility in disease control and prevention.

AB - PURPOSE: Dual-cure core build-up resins have been developed to take advantages of both self and light-cured resin. The aim of present study was to determine the polymerization characteristics of self and dual-cured modes of dual-cure core build-up composites evaluating degree of conversion (DC) and crosslink density by measurement of glass-transition temperature (Tg) and hardness decrease in ethanol. METHODS: Clearfil Dc Core Automix (CLF) and Grandio Core Dc (GR) core build-up resins were selected. Twelve specimens for both composites were polymerized using quartz-halogen-tungsten light curing unit (QTH) and 12 specimens polymerized chemically. DC was determined by ATR-FTIR spectroscopy. TG/DTA analysis was performed to determine Tg. Microhardness value of specimens was determined by Vickers-tester before and after specimens stored in absolute ethanol for 24h. RESULTS: One-way ANOVA showed no different DC values between dual and self-cured mode of GR and dual-cured CLF composites had higher DC than self-cured mode. Tg and percentage of softening in ethanol values of GR and CLF revealed significant difference between self and dual-cured mode. CONCLUSIONS: In comparison of GR and CLF, DC showed no statistical difference in both curing modes. However, dual and self-cured GR has statistically higher Tg values and lower percentage of softening in ethanol than CLF. Polymerization characteristics of dual-cure core build-up composites have superiority in dual-cured mode than self-cured. PMID- 27717750 TI - RISK pathway is involved in oxytocin postconditioning in isolated rat heart. AB - The reperfusion injury salvage kinase (RISK) pathway is a fundamental signal transduction cascade in the cardioprotective mechanism of ischemic postconditioning. In the present study, we examined the cardioprotective role of oxytocin as a postconditioning agent via activation of the RISK pathway (PI3K/Akt and ERK1/2). Animals were randomly divided into 6 groups. The hearts were subjected under 30minutes (min) ischemia and 100min reperfusion. OT was perfused 15min at the early phase of reperfusion. RISK pathway inhibitors (Wortmannin; an Akt inhibitor, PD98059; an ERK1/2 inhibitor) and Atosiban (an OT receptor antagonist) were applied either alone 10min before the onset of the ischemia or in the combination with OT during early reperfusion phase. Myocardial infarct size, hemodynamic factors, ventricular arrhythmia, coronary flow and cardiac biochemical marker were measured at the end of reperfusion. OT postconditioning (OTpost), significantly decreased the infarct size, arrhythmia score, incidence of ventricular fibrillation, Lactate dehydrogenase and it increased coronary flow. The cardioprotective effect of OTpos was abrogated by PI3K/Akt, ERK1/2 inhibitors and Atosiban. Our data have shown that OTpost can activate RISK pathway mostly via the PI3K/Akt and ERK1/2 signaling cascades during the early phase of reperfusion. PMID- 27717751 TI - Chemical quality and regulatory compliance of drinking water in Iceland. AB - Assuring sufficient quality of drinking water is of great importance for public wellbeing and prosperity. Nations have developed regulatory system with the aim of providing drinking water of sufficient quality and to minimize the risk of contamination of the water supply in the first place. In this study the chemical quality of Icelandic drinking water was evaluated by systematically analyzing results from audit monitoring where 53 parameters were assessed for 345 samples from 79 aquifers, serving 74 water supply systems. Compliance to the Icelandic Drinking Water Regulation (IDWR) was evaluated with regard to parametric values, minimum requirement of sampling, and limit of detection. Water quality compliance was divided according to health-related chemicals and indicators, and analyzed according to size. Samples from few individual locations were benchmarked against natural background levels (NBLs) in order to identify potential pollution sources. The results show that drinking compliance was 99.97% in health-related chemicals and 99.44% in indicator parameters indicating that Icelandic groundwater abstracted for drinking water supply is generally of high quality with no expected health risks. In 10 water supply systems, of the 74 tested, there was an indication of anthropogenic chemical pollution, either at the source or in the network, and in another 6 water supplies there was a need to improve the water intake to prevent surface water intrusion. Benchmarking against the NBLs proved to be useful in tracing potential pollution sources, providing a useful tool for identifying pollution at an early stage. PMID- 27717752 TI - Appendiceal involvement in a patient with Gaucher disease. AB - Almost any anatomical compartment may be involved in Gaucher disease (GD). Abdominal lymphadenopathy occurred during enzyme replacement therapy in more than a dozen children with GD so far. A fourteen-year-old boy from Serbia developed clinical signs of acute appendicitis six years after the onset of GD type 3 related abdominal lymphadenopathy. Ultrasound examination showed diffuse thickening of the intestinal wall in the ileocoecal region with periappendicular infiltration. An appendectomy was performed four months after conservative treatment with antibiotics. Histopathology revealed macrophages with cytological characteristics of Gaucher cells densely crammed in mesoappendiceal adipose tissue. Also the multifocal replacement of subserosal tissue by Gaucher cells and their infiltration to a variable depth of muscularis propria of the appendix were verified. Frank infiltration of the vermiform appendix with Gaucher cells represents a novel observation in a wide spectrum of manifestations reported in GD. A possible causative relationship of this infiltration with appendicitis is considered. PMID- 27717753 TI - Clinical and prognostic correlates of pulmonary congestion in coronary computed tomography angiography data sets. AB - BACKGROUND: Signs of pulmonary congestion obtained from cardiac computed tomography angiographic (coronary CTA) images have not previously been related to clinical congestion or outcome and the clinical value is, therefore, unknown. Our objective was to test the hypothesis that signs of pulmonary congestion predict clinical heart failure and adverse outcome in patients with myocardial infarction. METHODS: Coronary CTA was performed before invasive treatment in 400 prospectively included patients with non ST segment elevation myocardial infarction in an observational study. Using a previously described chest computed tomography evaluation algorithm, patients were classified as having "no congestion", "mild to moderate congestion" or "severe congestion". RESULTS: Using multivariate analyses, presence of pulmonary congestion on coronary CTA images was associated with age, female gender, left ventricular ejection fraction (LVEF) and left atrial size. The diagnostic accuracy for predicting clinical heart failure, defined as Killip class >1, was: sensitivity: 83%, specificity: 69%, positive predictive value: 25%, and negative predictive value: 97%. The median follow-up time was 50 months and the study end-point of death or hospitalization due to heart failure was reached in 68 (16%) patients. In a Cox proportional hazards model with adjustments for known risk factors and Killip class, the presence of "mild to moderate congestion" and "severe congestion" was independently associated with adverse outcome (Hazard ratio: 2.6 (95% CI:1.3-5.0) and 3.2 (1.3-7.5)). CONCLUSION: Signs of pulmonary congestion on coronary CTA images are closely correlated to cardiac dysfunction, predict clinical heart failure, and provide prognostic value independent of LVEF and Killip class. PMID- 27717754 TI - A new method for assessing the accuracy of full arch impressions in patients. AB - OBJECTIVE: To evaluate a new method of measuring the real deviation (trueness) of full arch impressions intraorally and to investigate the trueness of digital full arch impressions in comparison to a conventional impression procedure in clinical use. METHODS: Four metal spheres were fixed with composite using a metal application aid to the lower teeth of 50 test subjects as reference structures. One conventional impression (Impregum Penta Soft) with subsequent type-IV gypsum model casting (CI) and three different digital impressions were performed in the lower jaw of each test person with the following intraoral scanners: Sirona CEREC Omnicam (OC), 3M True Definition (TD), Heraeus Cara TRIOS (cT). The digital and conventional (gypsum) models were analyzed relative to the spheres. Linear distance and angle measurements between the spheres, as well as digital superimpositions of the spheres with the reference data set were executed. RESULTS: With regard to the distance measurements, CI showed the smallest deviations followed by intraoral scanners TD, cT and OC. A digital superimposition procedure yielded the same order for the outcomes: CI (15+/ 4MUm), TD (23+/-9MUm), cT (37+/-14MUm), OC (214+/-38MUm). Angle measurements revealed the smallest deviation for TD (0.06 degrees +/-0,07 degrees ) followed by CI (0.07 degrees +/-0.07 degrees ), cT (0.13 degrees +/-0.15 degrees ) and OC (0.28 degrees +/-0.21 degrees ). CONCLUSION: The new measuring method is suitable for measuring the dimensional accuracy of full arch impressions intraorally. CI is still significantly more accurate than full arch scans with intraoral scanners in clinical use. CLINICAL SIGNIFICANCE: Conventional full arch impressions with polyether impression materials are still more accurate than full arch digital impressions. Digital impression systems using powder application and active wavefront sampling technology achieve the most accurate results in comparison to other intraoral scanning systems (DRKS-ID: DRKS00009360, German Clinical Trials Register). PMID- 27717755 TI - Optical properties of pre-colored dental monolithic zirconia ceramics. AB - OBJECTIVES: The purposes of this study were to evaluate the optical properties of recently marketed pre-colored monolithic zirconia ceramics and to compare with those of veneered zirconia and lithium disilicate glass ceramics. METHODS: Various shades of pre-colored monolithic zirconia, veneered zirconia, and lithium disilicate glass ceramic specimens were tested (17.0*17.0*1.5mm, n=5). CIELab color coordinates were obtained against white, black, and grey backgrounds with a spectrophotometer. Color differences of the specimen pairs were calculated by using the CIEDE2000 (DeltaE00) formula. The translucency parameter (TP) was derived from DeltaE00 of the specimen against a white and a black background. X ray diffraction was used to determine the crystalline phases of monolithic zirconia specimens. Data were analyzed with 1-way ANOVA, Scheffe post hoc, and Pearson correlation testing (alpha=0.05). RESULTS: For different shades of the same ceramic brand, there were significant differences in L*, a*, b*, and TP values in most ceramic brands. With the same nominal shade (A2), statistically significant differences were observed in L*, a*, b*, and TP values among different ceramic brands and systems (P<0.001). The color differences between pre colored monolithic zirconia and veneered zirconia or lithium disilicate glass ceramics of the corresponding nominal shades ranged beyond the acceptability threshold. CONCLUSIONS: Due to the high L* values and low a* and b* values, pre colored monolithic zirconia ceramics can be used with additional staining to match neighboring restorations or natural teeth. CLINICAL SIGNIFICANCE: Due to their high value and low chroma, unacceptable color mismatch with adjacent ceramic restorations might be expected. PMID- 27717756 TI - Effect of toothbrushing duration and dentifrice quantity on enamel remineralisation: An in situ randomized clinical trial. AB - OBJECTIVES: The influence of toothbrushing duration and dentifrice quantity on fluoride efficacy against dental caries is poorly understood. This study investigated effects of these two oral hygiene factors on enamel remineralisation (measured as surface microhardness recovery [SMHR]), enamel fluoride uptake (EFU), and net acid resistance (NAR) post-remineralisation in a randomized clinical study using an in situ caries model. METHODS: Subjects (n=63) wore their partial dentures holding partially demineralised human enamel specimens and brushed twice-daily for two weeks, following each of five regimens: brushing for 120 or 45s with 1.5g of 1150ppm F (as NaF) dentifrice; for 120 or 45s with 0.5g of this dentifrice; and for 120s with 1.5g of 250ppm F (NaF) dentifrice. RESULTS: Comparing brushing for 120s against brushing for 45s, SMHR and EFU increased by 20.0% and 26.9% respectively when 1.5g dentifrice was used; and by 22.8% and 19.9% respectively when 0.5g dentifrice was used. Comparing brushing with 1.5g against brushing with 0.5g dentifrice, SMHR and EFU increased by 35.3% and 51.3% respectively when brushing for 120s, and by 38.4% and 43.0% respectively when brushing for 45s. Increasing brushing duration and dentifrice quantity also increased the NAR value. The effects of these two oral hygiene factors on SMHR, EFU, and NAR were statistically significant (p<0.05 in all cases). CONCLUSION: Brushing duration and dentifrice quantity have the potential to influence the anti-caries effectiveness of fluoride dentifrices. Study NCT01563172 on ClinicalTrials.gov. CLINICAL SIGNIFICANCE: The effect of two key oral hygiene regimen factors - toothbrushing duration and dentifrice quantity - on fluoride's anticaries effectiveness is unclear. This 2-week home-use in situ remineralisation clinical study showed both these factors can influence fluoride bioactivity, and so can potentially affect fluoride's ability to protect against caries. PMID- 27717757 TI - Multiple Phlebovirus (Bunyaviridae) genetic groups detected in Rhipicephalus, Hyalomma and Dermacentor ticks from southern Portugal. AB - In the last decade, various research groups have reported a large diversity of new tick-borne phleboviruses, mostly prompted by the discovery of important human pathogens such as the Heartland and severe fever with thrombocytopenia syndrome viruses. Since these analyses have rarely been conducted using ticks collected from Southern Europe, this study was carried out so as to bring new insights into the diversity of phleboviruses circulating in Southern Portugal. Tick specimens were collected from the vegetation (questing ticks) or directly from animals (feeding ticks), and the majority analysed in pools using a detection strategy targeting the large (L) viral genomic segment. A high number of pools revealed the presence of phebovirus sequences, regardless of gender (male/female), origin (questing/feeding) or even species of the tick analysed. These sequences apparently formed three different groups in phylogenetic trees, and encoded L proteins characterized by group-specific amino acid residues. Furthermore, under the conditions used, these viruses failed to replicate in both Vero and DH82 cells. The impact these viruses may have on human/animal health will be addressed in the future. PMID- 27717758 TI - Multiple resistance to acaricides in field populations of Rhipicephalus microplus from Rio Grande do Sul state, Southern Brazil. AB - Acaricide resistance is a major obstacle to the control of Rhipicephalus microplus. Historically, the indiscriminate use of chemical compounds has contributed to the selection of populations resistant to different classes of acaricides. Therefore, multiple acaricide resistance is an important threat to the chemical control of the cattle tick. To investigate the occurrence and extent of multiple resistance to acaricides in Southern Brazil we performed larval tests with cypermethrin, chlorpyriphos, amitraz, fipronil and ivermectin on 104 cattle tick field samples from different ranches in Rio Grande do Sul, between the years 2013 and 2015. Adult immersion tests with a commercial formulation mixture of chlorpyriphos and cypermethrin were performed on 75 samples. Four levels of resistance were established according to the mortality of larvae: Level I: mortality between 82% and 95%; Level II: mortality between 57% and 82%; Level III: mortality between 25% and 57%; and Level IV: mortality lower than 25%. Resistance to cypermethrin was detected in 98.08% of the samples evaluated, mostly at resistance level IV. The frequency of samples resistant to amitraz, chlorpyriphos, ivermectin and fipronil was 76.92%, 60.58%, 60.58% and 53.85% respectively. Multiple resistance to three or more compounds was found in 78.85% of the samples. The results obtained in this study are alarming and reveal a new scenario for the challenge of tick control using chemicals. This is an issue of high importance to cattle production systems where this tick is responsible for a high economic impact. PMID- 27717759 TI - Noncystic Fibrosis Bronchiectasis: Regional Abnormalities and Response to Airway Clearance Therapy Using Pulmonary Functional Magnetic Resonance Imaging. AB - RATIONALE AND OBJECTIVES: Evidence-based treatment and management for patients with bronchiectasis remain challenging. There is a need for regional disease measurements as focal distribution of disease is common. Our objective was to evaluate the ability of magnetic resonance imaging (MRI) to detect regional ventilation impairment and response to airway clearance therapy (ACT) in patients with noncystic fibrosis (CF) bronchiectasis, providing a new way to objectively and regionally evaluate response to therapy. MATERIALS AND METHODS: Fifteen participants with non-CF bronchiectasis and 15 age-matched healthy volunteers provided written informed consent to an ethics board-approved Health Insurance Portability and Accountability Act-compliant protocol and underwent spirometry, plethysmography, computed tomography (CT), and hyperpolarized 3He MRI. Bronchiectasis patients also completed a Six-Minute Walk Test, the St. George's Respiratory questionnaire, and Patient Evaluation Questionnaire (PEQ), and returned for a follow-up visit after 3 weeks of daily oscillatory positive expiratory pressure use. CT evidence of bronchiectasis was qualitatively reported by lobe, and MRI ventilation defect percent (VDP) was measured for the entire lung and individual lobes. RESULTS: CT evidence of bronchiectasis and abnormal VDP (14 +/- 7%) was observed for all bronchiectasis patients and no healthy volunteers. There was CT evidence of bronchiectasis in all lobes for 3 patients and in 3 +/- 1 lobes (range = 1-4) for 12 patients. VDP in lobes with CT evidence of bronchiectasis (19 +/- 12%) was significantly higher than in lobes without CT evidence of bronchiectasis (8 +/- 5%, P = .001). For patients, VDP in lung lobes with (P < .0001) and without CT evidence of bronchiectasis (P = .006) was higher than in healthy volunteers (3 +/- 1%). For all patients, mean PEQ-ease-bringing up-sputum (P = .048) and PEQ-patient-global-assessment (P = .01) were significantly improved post-oscillatory positive expiratory pressure. An improvement in regional VDP greater than the minimum clinical important difference was observed for 8 of the 14 patients evaluated. CONCLUSIONS: There was CT and MRI evidence of structure-function abnormalities in patients with bronchiectasis; in approximately half, there was evidence of ventilation improvements after airway clearance therapy. PMID- 27717760 TI - CT Pulmonary Angiography Using Automatic Tube Current Modulation Combination with Different Noise Index with Iterative Reconstruction Algorithm in Different Body Mass Index: Image Quality and Radiation Dose. AB - RATIONALE AND OBJECTIVES: This study aimed to determine the appropriate body mass index (BMI)-dependent noise index (NI) setting in computed tomography pulmonary angiography (CTPA) with automatic tube current modulation with adaptive statistical iterative reconstruction (ASiR). MATERIALS AND METHODS: A total of 480 patients who had a CTPA were divided into group A (18.5 kg/m2 <= BMI < 25 kg/m2), group B (25 kg/m2 <= BMI < 30 kg/m2), and group C (BMI >= 30 kg/m2), according to their BMI values; each group had 160 patients. The three groups were further randomly divided into four subgroups: A1, A2, A3, A4; B1, B2, B3, B4; and C1, C2, C3, C4, with corresponding NI values of 26, 36, 40, and 46, respectively. All images were restructured with the ASiR algorithm, and the images with the lowest NI (26 Hounsfield units) in each group were used as reference standard. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) for the pulmonary artery of each group were calculated. Subjective image quality was evaluated using a five-score method by two independent radiologists. The CT dose index of volume and dose-length product were recorded and were converted to effective dose (ED). SNR and CNR in the group A, B, and C subgroups were compared to repeated measures analysis of variance, and the subjective score, Volumetric CT dose index of volume, dose-length product, and ED were compared to one-way analysis of variance. RESULTS: For groups A and B, the SNR, CNR, and subjective scores of the images in their subgroups showed no statistical differences (P >.05). The ED in subgroups A4 and B4 was significantly lower than that in subgroups A1 (by 33.24%) and B1 (by 34.47%) (P <.01). For group C, there was no significant difference in the SNR, CNR, and the subjective image scores between subgroups C3 and C1 (P >.05). The ED in subgroup C3 was significantly lower than the ED in subgroup C1 (by 47.75%) (P <.01) CONCLUSIONS: Patient BMI-dependent NI settings that are higher than the recommended value may be used in CTPA with automatic tube current modulation and ASiR to effectively reduce radiation dose while maintaining diagnostic image quality. PMID- 27717761 TI - Quantitative Prediction of Stone Fragility From Routine Dual Energy CT: Ex vivo proof of Feasibility. AB - RATIONALE AND OBJECTIVES: Previous studies have demonstrated a qualitative relationship between stone fragility and internal stone morphology. The goal of this study was to quantify morphologic features from dual-energy computed tomography (CT) images and assess their relationship to stone fragility. MATERIALS AND METHODS: Thirty-three calcified urinary stones were scanned with micro-CT. Next, they were placed within torso-shaped water phantoms and scanned with the dual-energy CT stone composition protocol in routine use at our institution. Mixed low- and high-energy images were used to measure volume, surface roughness, and 12 metrics describing internal morphology for each stone. The ratios of low- to high-energy CT numbers were also measured. Subsequent to imaging, stone fragility was measured by disintegrating each stone in a controlled ex vivo experiment using an ultrasonic lithotripter and recording the time to comminution. A multivariable linear regression model was developed to predict time to comminution. RESULTS: The average stone volume was 300 mm3 (range: 134-674 mm3). The average comminution time measured ex vivo was 32 seconds (range: 7-115 seconds). Stone volume, dual-energy CT number ratio, and surface roughness were found to have the best combined predictive ability to estimate comminution time (adjusted R2 = 0.58). The predictive ability of mixed dual-energy CT images, without use of the dual-energy CT number ratio, to estimate comminution time was slightly inferior, with an adjusted R2 of 0.54. CONCLUSIONS: Dual-energy CT number ratios, volume, and morphologic metrics may provide a method for predicting stone fragility, as measured by time to comminution from ultrasonic lithotripsy. PMID- 27717762 TI - The Safety of Cardiac and Thoracic Magnetic Resonance Imaging in Patients with Cardiac Implantable Electronic Devices. AB - RATIONALE AND OBJECTIVES: Studies reporting the safety of magnetic resonance imaging (MRI) in patients with a cardiac implantable electronic device (CIED) have mostly excluded examinations with the device in the magnet isocenter. The purpose of this study was to describe the safety of cardiac and thoracic spine MRI in patients with a CIED. MATERIALS AND METHODS: The medical records of patients with a CIED who underwent a cardiac or thoracic spine MRI between January 2011 and December 2014 were reviewed. Devices were interrogated before and after imaging with reprogramming to asynchronous pacing in pacemaker dependent patients. The clinical interpretability of the MRI and peak and average specific absorption rates (SARs, W/kg) achieved were determined. RESULTS: Fifty eight patients underwent 51 cardiac and 11 thoracic spine MRI exams. Twenty-nine patients had a pacemaker and 29 had an implantable cardioverter defibrillator. Seventeen percent (n = 10) were pacemaker dependent. Fifty-one patients (89%) had non-MRI-conditional devices. There were no clinically significant changes in atrial and ventricular sensing, impedance, and threshold measurements. There were no episodes of device mode changes, arrhythmias, therapies delivered, electrical reset, or battery depletion. One study was prematurely discontinued due to a patient complaint of chest pain of which the etiology was not determined. Across all examinations, the average peak SAR was 2.0 +/- 0.85 W/kg with an average SAR of 0.35 +/- 0.37 W/kg. Artifact significantly limiting the clinical interpretation of the study was present in 33% of cardiac MRI studies. CONCLUSIONS: When a comprehensive CIED magnetic resonance safety protocol is followed, the risk of performing 1.5-T magnetic resonance studies with the device in the magnet isocenter, including in patients who are pacemaker dependent, is low. PMID- 27717763 TI - Mode of Death in Octogenarians Treated With Cardiac Resynchronization Therapy. AB - BACKGROUND: Cardiac resynchronization therapy (CRT) improves morbidity and mortality in heart failure with reduced ejection fraction (HFrEF) and electrical dyssynchrony. CRT patients in clinical practice are older compared with clinical trials. OBJECTIVE: To investigate clinical response, reverse remodeling, outcome, and mode of death in octogenarians receiving CRT. METHODS: Baseline characteristics, change in New York Heart Association (NYHA) functional class, reverse ventricular remodeling, heart failure readmissions, all-cause mortality, and mode of death were evaluated in CRT patients with comparison between octogenarians and nonoctogenarians. In addition, annual mortality rates of octogenarians undergoing CRT were compared with age-matched control subjects from the general population with the use of national actuarial tables. RESULTS: A total of 686 patients, including 178 octogenarians (26%), were followed for 38 +/ 22 months. Octogenarians exhibited a similar change in NYHA functional class (P = .640), left ventricular ejection fraction increase (P = .796), and decrease in end-diastolic (P = .441) and end-systolic (P = .312) diameter compared with their younger counterparts undergoing CRT. Octogenarians had a higher all-cause mortality risk (P < .001), but heart failure readmission risk did not differ (hazard ratio 0.916, 95% confidence interval 0.638-1.313; P = .632). A higher proportion of noncardiac deaths was observed in octogenarians (74%) versus younger patients (50%; P = .022), with worsening heart failure rather than malignant tachyarrhythmia being the main cardiac cause of death. Compared with an age-matched sample from the general population, octogenarians receiving CRT had an equivalent annual mortality rate (log-rank test: P = .444). CONCLUSIONS: Octogenarians retain the ability to mount a significant symptomatic and ventricular remodeling response after CRT, resulting in survival similar to the general age-matched population. PMID- 27717764 TI - Aluminium sulfate exposure: A set of effects on hydrolases from brain, muscle and digestive tract of juvenile Nile tilapia (Oreochromis niloticus). AB - Aluminium is a major pollutant due to its constant disposal in aquatic environments through anthropogenic activities. The physiological effects of this metal in fish are still scarce in the literature. This study investigated the in vivo and in vitro effects of aluminium sulfate on the activity of enzymes from Nile tilapia (Oreochromis niloticus): brain acetylcholinesterase (AChE), muscle cholinesterases (AChE-like and BChE-like activities), pepsin, trypsin, chymotrypsin and amylase. Fish were in vivo exposed during 14days when the following experimental groups were assayed: control group (CG), exposure to Al2(SO4)3 at 1MUg.mL-1 (G1) and 3MUg.mL-1 (G3) (concentrations compatible with the use of aluminium sulfate as coagulant in water treatment). In vitro exposure was performed using animals of CG treatment. Both in vivo and in vitro exposure increased cholinesterase activity in relation to controls. The highest cholinesterase activity was observed for muscle BChE-like enzyme in G3. In contrast, the digestive enzymes showed decreased activity in both in vivo and in vitro exposures. The highest inhibitory effect was observed for pepsin activity. The inhibition of serine proteases was also quantitatively analyzed in zymograms using pixel optical densitometry as area under the peaks (AUP) and integrated density (ID). These results suggest that the inhibition of digestive enzymes in combination with activation of cholinesterases in O. niloticus is a set of biochemical effects that evidence the presence of aluminium in the aquatic environment. Moreover, these enzymatic alterations may support further studies on physiological changes in this species with implications for its neurological and digestive metabolisms.

PMID- 27717766 TI - Effectiveness of activity trackers with and without incentives to increase physical activity (TRIPPA): a randomised controlled trial. AB - BACKGROUND: Despite the increasing popularity of activity trackers, little evidence exists that they can improve health outcomes. We aimed to investigate whether use of activity trackers, alone or in combination with cash incentives or charitable donations, lead to increases in physical activity and improvements in health outcomes. METHODS: In this randomised controlled trial, employees from 13 organisations in Singapore were randomly assigned (1:1:1:1) with a computer generated assignment schedule to control (no tracker or incentives), Fitbit Zip activity tracker, tracker plus charity incentives, or tracker plus cash incentives. Participants had to be English speaking, full-time employees, aged 21 65 years, able to walk at least ten steps continuously, and non-pregnant. Incentives were tied to weekly steps, and the primary outcome, moderate-to vigorous physical activity (MVPA) bout min per week, was measured via a sealed accelerometer and assessed on an intention-to-treat basis at 6 months (end of intervention) and 12 months (after a 6 month post-intervention follow-up period). Other outcome measures included steps, participants meeting 70 000 steps per week target, and health-related outcomes including weight, blood pressure, and quality of-life measures. This trial is registered at ClinicalTrials.gov, number NCT01855776. FINDINGS: Between June 13, 2013, and Aug 15, 2014, 800 participants were recruited and randomly assigned to the control (n=201), Fitbit (n=203), charity (n=199), and cash (n=197) groups. At 6 months, compared with control, the cash group logged an additional 29 MVPA bout min per week (95% CI 10-47; p=0.0024) and the charity group an additional 21 MVPA bout min per week (2-39; p=0.0310); the difference between Fitbit only and control was not significant (16 MVPA bout min per week [-2 to 35; p=0.0854]). Increases in MVPA bout min per week in the cash and charity groups were not significantly greater than that of the Fitbit group. At 12 months, the Fitbit group logged an additional 37 MVPA bout min per week (19-56; p=0.0001) and the charity group an additional 32 MVPA bout min per week (12-51; p=0.0013) compared with control; the difference between cash and control was not significant (15 MVPA bout min per week [-5 to 34; p=0.1363]). A decrease in physical activity of -23 MVPA bout min per week (95% CI -42 to -4; p=0.0184) was seen when comparing the cash group with the Fitbit group. There were no improvements in any health outcomes (weight, blood pressure, etc) at either assessment. INTERPRETATION: The cash incentive was most effective at increasing MVPA bout min per week at 6 months, but this effect was not sustained 6 months after the incentives were discontinued. At 12 months, the activity tracker with or without charity incentives were effective at stemming the reduction in MVPA bout min per week seen in the control group, but we identified no evidence of improvements in health outcomes, either with or without incentives, calling into question the value of these devices for health promotion. Although other incentive strategies might generate greater increases in step activity and improvements in health outcomes, incentives would probably need to be in place long term to avoid any potential decrease in physical activity resulting from discontinuation.

PMID- 27717768 TI - Comparative effectiveness and cost-effectiveness of treat-to-target versus benefit-based tailored treatment of type 2 diabetes in low-income and middle income countries: a modelling analysis. AB - BACKGROUND: Optimal prescription of blood pressure, lipid, and glycaemic control treatments for adults with type 2 diabetes remains unclear. We aimed to compare the effectiveness and cost-effectiveness of two treatment approaches for diabetes management in five low-income and middle-income countries. METHODS: We developed a microsimulation model to compare a treat-to-target (TTT) strategy, aiming to achieve target levels of biomarkers (blood pressure <130/80 mm Hg, LDL <2.59 mmol/L, and HbA1c <7% [ie, 53.0 mmol/mol]), with a benefit-based tailored treatment (BTT) strategy, aiming to lower estimated risk for complications (to a 10 year cardiovascular risk <10% and lifetime microvascular risk <5%) on the basis of age, sex, and biomarker values. Data were obtained from cohorts in China, Ghana, India, Mexico, and South Africa to span a spectrum of risk profiles. FINDINGS: The TTT strategy recommended treatment to a larger number of people-who were generally at lower risk of diabetes complications-than the BTT. The BTT strategy recommended treatment to fewer people at higher risk. Compared with the TTT strategy, the BTT strategy would be expected to avert 24.4-30.5% more complications and be more cost-effective from a societal perspective (saving US$4.0-300.0 per disability-adjusted life-year averted in the countries simulated). Alternative treatment thresholds, matched by total cost or population size treated, did not change the comparative superiority of the BTT strategy, nor did titrating treatment using fasting plasma glucose (for areas without HbA1c testing). However, if insulin were unavailable, the BTT strategy would no longer be superior for preventing microvascular events and was superior only for preventing cardiovascular events. INTERPRETATION: A BTT strategy is more effective and cost-effective than a TTT strategy in low-income and middle-income countries for prevention of both cardiovascular and microvascular complications of type 2 diabetes. However, the superiority of the BTT strategy for averting microvascular complications is contingent on insulin availability.

AB - Personality traits such as conscientiousness as self-reported by individuals can help predict a range of outcomes, from job performance to longevity. Asking others to rate the personality of their acquaintances often provides even better predictive power than using self-report. Here, we examine whether peer-reported personality can provide a better link between brain function, namely threat related amygdala activity, and future health-related behavior, namely problem drinking, than self-reported personality. Using data from a sample of 377 young adult university students who were rated on five personality traits by peers, we find that higher threat-related amygdala activity to fearful facial expressions is associated with higher peer-reported, but not self-reported, conscientiousness. Moreover, higher peer-reported, but not self-reported, conscientiousness predicts lower future problem drinking more than one year later, an effect specific to men. Remarkably, relatively higher amygdala activity has an indirect effect on future drinking behavior in men, linked by peer reported conscientiousness to lower future problem drinking. Our results provide initial evidence that the perceived conscientiousness of an individual by their peers uniquely reflects variability in a core neural mechanism supporting threat responsiveness. These novel patterns further suggest that incorporating peer reported measures of personality into individual differences research can reveal novel predictive pathways of risk and protection for problem behaviors.

AB - Bovine serum is an important factor for the optimal growth of Babesia bovis in vitro. This protozoan can be cultured in M-199 with Earle's salts medium (M-199) supplemented with 40% bovine serum (BS). In the present study, four media were assessed along with the control medium M-199. The effect on the proliferation of B. bovis in vitro was tested when these media were combined with insulin (Ins), transferrin (Trans) and selenite (Sel) in the absence of bovine serum. Treatment with Advanced DMEM/F12 medium (A-DMEM/F12) achieved the highest percentage of parasitized erythrocytes (PPE), reaching a maximum value of 9.59%. A-DMEM/F12 medium supplemented with a mixture of Ins (2000 mg/L), Trans (1100 mg/L), and Sel (1.34 mg/L) allowed for the adaptation and proliferation of B. bovis without bovine serum, showed a constant increase in PPE, and reached a maximum value of 9.7% during seven cycles of in vitro culture. It was concluded that continuous proliferation of B. bovis in vitro could be achieved using A-DMEM/F12 medium supplemented with Ins-Trans-Sel, without bovine serum. After adaptation for proliferation in serum-free medium, the B. bovis strain of parasites could have future use in the study of this economically important protozoan species that affects cattle. PMID- 27717770 TI - Genome-wide association analysis of secondary imaging phenotypes from the Alzheimer's disease neuroimaging initiative study. AB - The aim of this paper is to systematically evaluate a biased sampling issue associated with genome-wide association analysis (GWAS) of imaging phenotypes for most imaging genetic studies, including the Alzheimer's Disease Neuroimaging Initiative (ADNI). Specifically, the original sampling scheme of these imaging genetic studies is primarily the retrospective case-control design, whereas most existing statistical analyses of these studies ignore such sampling scheme by directly correlating imaging phenotypes (called the secondary traits) with genotype. Although it has been well documented in genetic epidemiology that ignoring the case-control sampling scheme can produce highly biased estimates, and subsequently lead to misleading results and suspicious associations, such findings are not well documented in imaging genetics. We use extensive simulations and a large-scale imaging genetic data analysis of the Alzheimer's Disease Neuroimaging Initiative (ADNI) data to evaluate the effects of the case control sampling scheme on GWAS results based on some standard statistical methods, such as linear regression methods, while comparing it with several advanced statistical methods that appropriately adjust for the case-control sampling scheme. PMID- 27717772 TI - Invasion by Trichinella spiralis infective larvae affects the levels of inflammatory cytokines in intestinal epithelial cells in vitro. AB - As we all know, invasion of host intestinal epithelium is very important for T. spiralis to complete successfully their life cycle. However, the mechanisms that the intestinal infective larvae (IIL) invade and migrate in the intestinal epithailial cells (IECs) remain unclear until now. The related researches have been hindered since a readily operable in vitro normal model. In our earlier study, an in vitro normal IEC invasion model was established for the first time, and the abilities of the normal IECs to initiate mucosal inflammatory responses to invasion by the IIL in vitro were evaluated in this study. When the IIL were overlaid on the normal mouse IEC monolayers, they quickly within seconds invaded the monolayers and move within the IECs, leaving trails of damaged cells. Then the larvae were found to have started their molting at 12 h, and the complete cuticle was found at 24 h. The percentage of the first molt in the larvae was about 62.3%, and the percentage of the 2nd-4th molt was about 38.2% at 36 h. Real time PCR showed that the mRNA levels of interleukin-1beta (IL-1beta), IL-8, epithelial neutrophil-activating peptide 78 (ENA-78), inducible nitric oxide synthase (iNOS), and monocyte chemotactic protein 2 (MCP-2) were elevated in the IECs after 7 h of infection after invasion by the IIL, and their levels were enhanced with the increase of larvae number. No changes in tumor necrosis factor alpha (TNF-alpha) mRNA were observed after the IIL invasion. Secretion increases of IL-1beta and IL-8 from the IEC monolayers invaded by T. spiralis were also detected by ELISA. Secretion increases of proinflammatory cytokines and inflammatory mediators in normal IECs can launch the acute inflammatory in response to the IIL invasion. This study would be helpful in further investigating the relationship between the host and T. spiralis, and the immune escape mechanisms of the niche established by T. spiralis.

AB - Cryptosporidiosis is predominantly a gastrointestinal disease of humans and other animals, caused by various species of protozoan parasites representing the genus Cryptosporidium. Detection of Cryptosporidium spp. in human clinical samples is central to the prevention, surveillance and control of cryptosporidiosis, particularly given that there is presently no broadly applicable treatment regimen for this disease. A non-radioactive, genus specific DNA dot blot hybridization assay was developed using Digoxigenin (DIG) labelled probes to detect Cryptosporidium DNA in human clinical samples. Four hundred fifty (n = 450) clinical samples were subjected to microscopic examination, Polymerase Chain Reaction assay (PCR), Dot blot hybridization assay and Real Time PCR assay. A total of forty-one (n = 41) samples were positive by microscopy, forty-two (n = 42) by both PCR assay and dot blot hybridization assay and forty-three (n = 43) by Real Time PCR assay. Dot blot hybridization assay with a sensitivity of 95.5% and specificity of 99.75% could be an ideal choice for routine investigation of a large number of samples in a clinical setting as well as field. PMID- 27717774 TI - Appetite regulating factors in pacu (Piaractus mesopotamicus): Tissue distribution and effects of food quantity and quality on gene expression. AB - The pacu Piaractus mesopotamicus is an omnivorous fish considered a promising species for aquaculture. Little is known about the endocrine regulation of feeding in this species. In this study, transcripts for orexin, cocaine and amphetamine regulated transcript (CART), cholecystokinin (CCK) and leptin were isolated in pacu. Orexin, CCK and leptin have widespread mRNA distributions in brain and periphery, CART is limited to the brain. To examine the role of these peptides in the regulation of feeding and energy status, mRNA expression levels were compared between fed and fasted fish and around feeding time. Both orexin and CART brain expressions were affected by fasting and displayed periprandial changes, suggesting a role in both short- and long-term regulation of feeding. CCK intestinal expression decreased in fasted fish and displayed periprandial changes, suggesting CCK acts as a peripheral satiety factor. Leptin was not affected by fasting but displayed periprandial changes, suggesting a role as a short-term regulator. To examine if these peptides are affected by diet, brain and gut expressions were assessed in fish fed with different diets containing soy protein concentrate. Food intake, weight gain and expressions of orexin, CART, CCK and leptin were little affected by replacement of fish protein with soy protein, suggesting that pacu is able to tolerate and grow well with a diet rich in plant material. Overall, our results suggest that orexin, CART, CCK and leptin are involved in the physiology of feeding of pacu and that their expressions are little affected by plant-based diets. PMID- 27717775 TI - The Effect of l-Arginine on Dural Healing After Experimentally Induced Dural Defect in a Rat Model. AB - BACKGROUND: Incomplete repair of the dura mater may result in numerous complications such as cerebrospinal fluid leakage and meningitis. For this reason, accurate repair of the dura mater is essential. In this study, the effect of systemic and local supplementation of l-arginine on dural healing was evaluated. METHODS: Thirty male Wistar rats were used and divided into control, local, and systemic l-arginine groups, with 10 rats in each. In each group, a 5 mm experimental incision was made at the lumbar segment of the dura mater and cerebrospinal fluid leakage was induced. Each group was divided into 2 subgroups and at the end of the first and sixth weeks, the rats were killed and the damaged segments of the dura were separated, histologically evaluated and the dural healing indicators including cell types, granulation tissue formation, collagen deposit, and vascularization were compared between groups. RESULTS: The systematic supplementation of l-arginine showed a significant effect in dural healing compared with the control group. After the first week, granulation formation increased considerably (P < 0.031), and after 6 weeks, collagen deposition and neovascularization were significantly different compared with the control group (P < 0.030; P < 0.009). In comparison between different groups at the end of the first and sixth weeks, maximum changes in healing indicators were observed in the systemic group and the least variations were related to the control group. CONCLUSIONS: The systemic supplementation of l-arginine may accelerate dural healing by increasing the level of granulation tissue formation, collagen deposition, and vascularization. PMID- 27717776 TI - Predictors of Delayed Cerebral Ischemia in Patients with Aneurysmal Subarachnoid Hemorrhage with Asymptomatic Angiographic Vasospasm on Admission. AB - BACKGROUND: Risk of delayed cerebral ischemia (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH) with asymptomatic angiographic vasospasm on admission is unclear in the literature. The goal of this study is to identify predictors of clinical DCI in this group of patients. METHODS: An exploratory subgroup analysis was conducted in the SAHIT (Subarachnoid Hemorrhage International Trialists) data repository to identify predictors of clinical DCI in patients with good-grade aSAH (World Federation of Neurological Surgeons grade I and II) with angiographic vasospasm on admission. Predictors considered include age, sex, systolic blood pressure at presentation, World Federation of Neurological Surgeon grade, Fisher grade, aneurysm size and location, treatment modality, hydrocephalus requiring external ventricular drain insertion, and severity of vasospasm. The predictors were ranked based on dominance analysis with R2 as fit statistics and assessed in a set of logistic regression analysis models. RESULTS: Four data sets out of 16 studies in the SAHIT database were analyzed, with a total of 4125 patients. One hundred and ninety-one patients (4.6%) had asymptomatic angiographic vasospasm at admission. Of those, 78 patients (40.8%) developed clinical DCI. Univariate analysis showed significant associations between severe vasospasm on admission and development of clinical DCI (odds ratio, 9.5, 95% confidence interval, 2.07-43.50; P = 0.004). None of the studied predictors was associated with the development of clinical DCI on multivariate analysis. CONCLUSIONS: Asymptomatic angiographic vasospasm in patients with good-grade aSAH on admission is uncommon. Further studies are needed to identify high-risk patients for the development of DCI in the context of asymptomatic early vasospasm. PMID- 27717777 TI - Application of Unilateral C2 Translaminar Screw in the Treatment for Atlantoaxial Instability as an Alternative or Salvage of Pedicle Screw Fixation. AB - OBJECTIVE: To analyze the clinical outcomes of our experience with the unilateral C2 translaminar screw technique and evaluate its feasibility as an alternative or salvage of the pedicle screw. METHODS: Eleven consecutive adult patients with atlantoaxial instability who underwent hybrid fixation techniques using unilateral translaminar screw combined with contralateral C2 pedicle screw and bilateral C1 LMS via posterior arch from January 2010 to December 2013 were retrospectively investigated. The surgical techniques and treatment procedures were described, and clinical symptoms, neurologic function, and imaging appearance were evaluated. RESULTS: The average age in our series was 40.9 years. No vascular or neurologic injuries occurred. No hardware failure or breach of C2 lamina or pedicle was observed in postoperative radiographs or computed tomography scans. Good bone union was achieved in all patients. There were no cases of screw pullout or pseudarthrosis. CONCLUSIONS: Patients with variant vertebral artery or osseous anomaly are good candidates for the hybrid translaminar screw technique as an alternative to or salvage of C2 pedicle screw.

AB - INTRODUCTION: QuantiFERON(r)-TB Gold Plus (QFT-Plus) is the new generation of QuantiFERON-TB Gold In-Tube test to identify latent tuberculosis infection (LTBI). QFT-Plus includes TB1 and TB2 tubes which contain selected Mycobacterium tuberculosis (Mtb) peptides designed to stimulate both CD4 and CD8 T-cells. Aim of this study is the flow cytometric characterization of the specific CD4 and CD8 T-cell responses to Mtb antigens contained within QFT-Plus. METHODS: We enrolled 27 active tuberculosis (TB) patients and 30 LTBI individuals. Following stimulation with TB1 and TB2, antigen-specific T-cells were characterized by flow cytometry. Data were also correlated with the grade of TB severity. RESULTS: TB1 mainly elicited a CD4 T-cell response while TB2 induced both CD4 and CD8 responses. Moreover, the TB2-specific CD4 response was detected for both active TB and LTBI patients, whereas the TB2-specific CD8 response was primarily associated with active TB (p = 0.01). CONCLUSIONS: To our knowledge, we report the first characterization of the CD4 and CD8 T-cell response to QFT-Plus. CD8 T cell response is mainly due to TB2 stimulation which is largely associated to active TB. These results provide a better knowledge on the use of this assay. PMID- 27717780 TI - HIV-infection and psychiatric illnesses - A double edged sword that threatens the vision of a contained epidemic: The Greater Stockholm HIV Cohort Study. AB - CONTEXT: The Greater Stockholm HIV Cohort Study is an initiative to provide longitudinal information regarding the health of people living with HIV. OBJECTIVE: Our aim was to explore the prevalence of HIV and its association with psychiatric co-morbidities. DESIGN, SETTING AND PARTICIPANTS: All patients with a recorded diagnosis of HIV (any position of the ICD-10 codes B20-B24) were identified during the period 2007-2014 and related to the total population in Stockholm by January 1, 2015, N = 2.21 million. The age at diagnosis, gender, and first occurrence of an HIV diagnosis was recorded. Analyses were done by age and gender. Prevalence of psychiatric co-morbidities amongst HIV patients were recorded. MAIN OUTCOME MEASURES: Age-adjusted odds ratios with 95% confidence intervals were calculated with logistic regression for prevalent psychiatric co morbidities in HIV infected individuals compared to the prevalence in the general population. RESULTS: The total prevalence of HIV was 0.16%; females 0.10% (n = 1134) and males 0.21% (n = 2448). HIV-infected people were more frequently diagnosed with psychiatric illnesses and drug abuse. In females and males with HIV-diagnosis respectively, drug dependence disorder was 7.5 (7.76% vs 1.04%) and 5.1 (10.17% vs 1.98%) times higher, psychotic disorders were 6.3 (2.65% vs 0.42%) and 2.9 (1.43% vs 0.49%) times higher, bipolar disorder was 2.5 (1.41% vs 0.57%) and 3 (1.02% vs 0.34%) times higher, depression diagnosis was 1.5 (8.47% vs 5.82%) and 3.4 (10.17% vs 2.97%) higher, trauma-related disorder was 1.5 (6.00% vs 4.10%) respectively 2.9 (4.45% vs 1.56%) times higher, anxiety disorder was 1.2 (6.88% vs 5.72%) and 2.2 (6.54% vs 2.93%) times higher than in their non infected peers. CONCLUSION: Despite effective ART, many individuals with HIV have an impaired mental health and a history of drug abuse that may threaten the vision of a contained epidemic. PMID- 27717781 TI - 1,3-beta-d-Glucan testing is highly specific in patients undergoing dialysis treatment. AB - BACKGROUND: The aim of this combined in-vitro and in-vivo study was to investigate whether state of the art dialysis modalities produce false positive serum 1,3-beta-d-Glucan (BDG) levels. METHODS: Dialysis fluid for simulated dialysis treatments was spiked with BDG from different sources. Samples were taken from the dialysate and dialyzer blood compartments at various time points. In addition, serum samples were obtained in three groups of patients without invasive fungal disease: a.) twelve patients on chronic hemodialysis (HD)/hemodiafiltration (HDF); b.) ten patients on continuous ambulatory peritoneal dialysis (CAPD); and c.) ten patients with stable chronic kidney disease (CKD) but without dialysis. RESULTS: Median BDG levels in BDG spiked dialysate were 3250.9, 2050.4, and 390.1 pg/ml respectively. All corresponding samples from the blood compartments were BDG negative. In HD/HDF patients no increase of serum BDG levels could be observed over the duration of treatment. 71/72 BDG tests in this group remained negative. BDG tests were also negative in 9/10 CAPD patients, both in in- and outflow dialysates as well as in all ten patients with CKD. CONCLUSION: We conclude that state of the art renal replacement therapies using up-to-date treatments are not a cause of falsely elevated serum BDG levels. PMID- 27717782 TI - Incidence and mortality of herpes simplex encephalitis in Denmark: A nationwide registry-based cohort study. AB - OBJECTIVES: We aimed to investigate the incidence and mortality of herpes simplex encephalitis (HSE) in a nationwide cohort. METHODS: From the Danish National Patient Registry, we identified all adults hospitalised with a first-time diagnosis of HSE in Denmark during 2004-2014. The HSE diagnoses were verified using medical records and microbiological data. Patients were followed for mortality through the Danish Civil Registry System. We estimated age-standardised incidence rates of HSE and 30-day, 60-day, and 1-year cumulative mortality. Furthermore, we assessed whether calendar year, age, gender, level of comorbidity, virus type, and department type was associated with HSE mortality. RESULTS: We identified a total of 230 cases of HSE. Median age was 60.7 years (interquartile range: 49.3-71.6). The overall incidence rate was 4.64 cases per million population per year (95% confidence interval: 4.06-5.28). The cumulative mortality within 30 days, 60 days, and 1 year of the HSE admission was 8.3%, 11.3%, and 18.6%, respectively. Advanced age and presence of comorbidity were associated with increased 60-day and 1-year mortality. CONCLUSIONS: This nationwide study of verified HSE found a higher incidence than reported in previous nationwide studies. Presence of comorbidity was identified as a novel adverse prognostic factor. Mortality rates following HSE remain high. PMID- 27717784 TI - The prevalence of non-tuberculous mycobacterial infections in mainland China: Systematic review and meta-analysis. AB - Despite increasing attention towards the non-tuberculous mycobacterial (NTM) diseases, the overall epidemiological information remains unavailable for China. A systematic review and meta-analysis was conducted using data of 105 qualified publications from Chinese mainland. The assay demonstrated that the prevalence of NTM infections among tuberculosis suspects was 6.3% (5.4%-7.4%) in mainland, while the Southeastern region had the highest NTM prevalence at 8.6% (7.1% 10.5%). In Northern China, slow growing mycobacteria (SGM) consistituted 63.7% of all the NTM isolates, while this rate in Southern China was 53.0%. More rapid growing mycobacteria (RGM) were present in southern China than the northern (chi2 = 57.996, P < 0.001). According to the coastal provinces' data (from north to south), the NTM prevalence rate and the number of isolated NTM species increased apparently in accordance with geographic latitude. The information obtained in this assay will facilitate the NTM disease diagnosis and screening policy making in China.

PMID- 27717783 TI - Tuberculosis-diabetes co-morbidity is characterized by heightened systemic levels of circulating angiogenic factors. AB - BACKGROUND: Tuberculosis-diabetes co-morbidity (TB-DM) is characterized by increased inflammation with elevated circulating levels of inflammatory cytokines and other factors. Circulating angiogenic factors are intricately involved in the angiogenesis-inflammation nexus. METHODS: To study the association of angiogenic factors with TB-DM, we examined the systemic levels of VEGF-A, VEGF-C, VEGF-D, VEGF-R1, VEGF-R2, VEGF-R3 in individuals with either TB-DM (n = 44) or TB alone (n = 44). RESULTS: Circulating levels of VEGF-A, C, D, R1, R2 and R3 were significantly higher in TB-DM compared to TB individuals. Moreover, the levels of VEGF-A, C, R2 and/or R3 were significantly higher in TB-DM with bilateral or cavitary disease or with hemoptysis, suggesting an association with both disease severity and adverse clinical presentation. The levels of these factors also exhibited a significant positive relationship with bacterial burdens and HbA1c levels. In addition, VEGF-A, C and R2 levels were significantly higher (at 2 months of treatment) in culture positive compared to culture negative TB-DM individuals. Finally, the circulating levels of VEGF-A, C, D, R1, R2 and R3 were significantly reduced following successful chemotherapy at 6 months. CONCLUSION: Our data demonstrate that TB-DM is associated with heightened levels of circulating angiogenic factors, possibly reflecting both dysregulated angiogenesis and exaggerated inflammation. PMID- 27717786 TI - Production, purification, and characterization of metalloprotease from Candida kefyr 41 PSB. AB - A thermostable metalloprotease, produced from an environmental strain of Candida kefyr 41 PSB, was purified 16 fold with a 60% yield by cold ethanol precipitation and affinity chromatography (bentonite-acrylamide-cysteine microcomposite). The purified enzyme appeared as a single protein band at 43kDa. Its optimum pH and temperature points were found to be 7.0 and 105 degrees C, respectively. Km and Vmax values of the enzyme were determined to be 3.5mg/mL and 4.4MUmolmL-1min-1, 1.65mg/mL and 6.1MUmolmL-1min-1, using casein and gelatine as the substrates, respectively. The activity was inhibited by using ethylenediamine tetraacetic acid (EDTA), indicating that the enzyme was a metalloprotease. Stability of the enzyme was investigated by using thermodynamic and kinetic parameters. The thermal inactivation profile of the enzyme conformed to the first order kinetics. The half life of the enzyme at 95, 105, 115, 125 and 135 degrees C was 1310, 610, 220, 150, and 86min, respectively. PMID- 27717787 TI - A protease-resistant alpha-galactosidase from Pleurotus djamor with broad pH stability and good hydrolytic activity toward raffinose family oligosaccharides. AB - An acidic alpha-galactosidase designated as PDGI (Pleurotus djamor alpha galactosidase) was purified to homogeneity with 290-fold purification and a specific activity of 52.18 units/mg by means of ion exchange chromatography and gel filtration chromatography. PDGI is a monomeric protein exhibiting a molecular mass of 60kDa in SDS-PAGE and gel filtration. The optimum pH and temperature of the enzyme with pNPGal as substrate were 5.0 and 53.5 degrees C, respectively. It displayed great pH stability within the pH range 3.0-10.0. Besides, the enzyme harbored remarkable resistance to acid protease and varying degrees of tolerance to other proteases: trypsin>collagenase Type-I>alpha-chymotrypsin neutral protease>proteinaseK. It was strongly inhibited by K+, Cd2+, Cu2+, Hg2+, Al3+, Fe3+ and Ag + ions. The chemical modification reagents diethypyrocarbonate (DEPC), 2,3-butanedione (DIC) and trinitrophenol (TNBS) increased the activity of PDGI 1.5-fold whereas N-bromosuccinimide (NBS) and parachloro-mercuri-benzoate (PCMB) drastically suppressed its activity. PDGI displayed activity toward stachyose and raffinose. The Km values for hydrolysis of pNPGal, stachyose and raffinose were 0.76, 7.63 and 6.29mM, respectively. Furthermore, PDGI degraded raffinose and sthachyose. These results suggest that PDGI has great potential for elimination of the non-digestible and flatulence-causing oligosaccharides stachyose and raffinose from legumes. PMID- 27717788 TI - In vitro and in silico studies of the interaction of three tetrazoloquinazoline derivatives with DNA and BSA and their cytotoxicity activities against MCF-7, HT 29 and DPSC cell lines. AB - In this study, the interaction of three [1,2,3,4]tetrazolo[5,1-b]-quinazolin-8 one derivatives with salmon sperm DNA and BSA was investigated experimentally and theoretically. Fluorescence and absorption spectroscopy techniques were applied to determine the probable interaction mechanism and correlated binding constants and thermodynamic parameters. It was found that the compounds intercalate into the DNA duplex via minor groove in a moderately strong fashion with the binding constants of 104M-1. The values of binding constant for the interaction with BSA at different temperatures were also calculated to be in the range of 1.06*103 3.54*108M-1 indicating the relatively high propensity of the compounds to BSA. In vitro cytotoxicity studies on the effect of the compounds on MCF-7 and HT-29 cancerous cell lines as well as DPSC normal cell line were performed using MTT assay. It was observed that the compounds exhibited selective inhibitory effect against cancer cell growth. Moreover, each of the title compounds was separately docked to DNA and BSA using Autodock Vina as a molecular docking program. The obtained theoretical results were in good agreement with those obtained from Experimental studies. PMID- 27717789 TI - The use of sugar beet pulp lignin for the production of vanillin. AB - The objectives of this work is to produce vanillin from sugar beet pulp by lignin oxidation and evaluate the effect of process parameters (temperature, partial pressure of oxygen, reaction time, CuSO4 as a catalyst) on the yield of vanillin. Purification and separation of vanillin from pressurized extract was carried out by organic solvent and crystallization. HPLC, FT-IR, H NMR, GC/MS and DSC methods were performed to approve the vanillin crystal. Results showed that production of vanillin was significantly affected by four parameters, and an optimal conditions for production of vanillin was found 4.3bar for an oxygen partial pressure under a temperature of 156 degrees C and duration of time 30min without CuSO4, corresponding to 1439.3mg/100g vanillin. Thermal property of syntesis vanillin was coincide to DSC pure vanillin curve but there were differences in DeltaH degrees f and DeltaHc. PMID- 27717790 TI - Development of the Hypogonadism Impact of Symptoms Questionnaire Short Form: Qualitative Research. AB - INTRODUCTION: Hypogonadism in men is often associated with poor libido, erectile dysfunction, irritability, fatigue, and psychological and relationship problems. Many of these symptoms can be best assessed through patient report. The 28-item Hypogonadism Impact of Symptoms Questionnaire (HIS-Q) was developed to evaluate hypogonadism symptoms in men with low testosterone in the context of clinical trials. AIM: To develop a briefer version of the HIS-Q that could be practical for use in treatment settings. METHODS: Participants with low testosterone levels and symptoms consistent with hypogonadism were recruited through clinical sites. Focus groups and interviews were conducted to elicit symptom concepts and identify those that were most relevant to patients, including changes as a consequence of treatment. MAIN OUTCOME MEASURES: Systematic analysis of the qualitative data and expert clinician input were used to develop the HIS-Q short form (HIS-Q-SF). One-on-one cognitive interviews were conducted to confirm the content validity of the HIS-Q-SF. RESULTS: Thirty-five men participated in this qualitative research. Concept elicitation was conducted through focus group discussions (n = 18) and telephone interviews (n = 2); then, the draft HIS-Q-SF was evaluated through cognitive interviews (n = 15). The mean age of total sample was 53.2 +/- 6.8 years, and the mean serum total testosterone level was 184.9 +/- 55.2 ng/dL. Results suggest that the HIS-Q-SF has demonstrated content validity, including the content coverage, comprehensibility, and the appropriateness of the response options and recall period. The final version of the HIS-Q-SF includes 17 items and is aligned with the original longer version of the instrument. CONCLUSION: The HIS-Q-SF is a comprehensive measurement of hypogonadism symptom severity in men. Content coverage and content validity were confirmed. The instrument will be evaluated further to establish the psychometric characteristics and to assess the utility of the measurement in clinical treatment settings. PMID- 27717791 TI - Patient preferences for inflammatory bowel disease treatment objectives. AB - BACKGROUND: There is currently little evidence about what treatment objectives most interest patients with inflammatory bowel disease (IBD). AIMS: To determine patient preferences regarding IBD treatment objectives, specially the attributes they value most and the symptoms to be controlled as a priority. METHODS: Prospective, observational, anonymous study conducted in 117 outpatients with Crohn's disease or ulcerative colitis. RESULTS: The most important treatment objectives from the patients' perspective were: improving quality of life (40.2% of patients), and completely resolving symptoms (33.3%). Only 12.8% of patients indicated having a completely normal colonoscopy as a preferred objective. The symptoms the patients considered to be most important when prioritizing their control were: abdominal pain (23.1% of patients), and bowel movement urgency (17.1%). The preferred treatment objectives were similar for Crohn's disease and ulcerative colitis patients. CONCLUSIONS: Improving quality of life and completely controlling symptoms are the priority treatment objectives for IBD patients, with abdominal pain being the most important symptom. Conversely, therapeutic objective target goals proposed by physicians, such as healing the mucosal lesions, are not a priority for most patients. This indicates that there are discrepancies between patient and physician expectations, which should be taken into account if a patient-centered care model is to be implemented. PMID- 27717792 TI - Beta blockers and cirrhosis, 2016. AB - To date, non-selective beta blockers (NSBBs) are a cornerstone in the treatment of portal hypertension. During the last years, our understanding of the potential benefits of early initiation of NSBB treatment, their effects beyond the prevention of variceal bleeding (i.e., their non-hemodyamic effects), as well as potential detrimental effects in patients with advanced disease has continuously evolved. In addition, we have learned that not all NSBBs are equal. Due to its additional anti-alpha1-adrenergic activity, carvedilol has been shown to be more potent in decreasing portal pressure, but might lead to more pronounced decreases in systemic arterial pressure, when compared to conventional NSBBs. It might be particularly beneficial in 'early' portal hypertension, when potential detrimental effects on systemic hemodynamics are less critical. In contrast, there is increasing evidence that the use of carvedilol or high NSBB doses should be carefully scrutinized in patients with severe or refractory ascites. Our review summarizes the current knowledge on the use of NSBBs for preventing variceal bleeding and other decompensating events and provides guidance for their safe use in hemodynamically 'vulnerable' patient populations. Finally, we also highlight areas for further research. PMID- 27717793 TI - The effect of CYP3A5 genetic polymorphisms on adverse events in patients with ulcerative colitis treated with tacrolimus. AB - BACKGROUND: Tacrolimus is an immunosuppressive agent, used in the remission induction therapy of ulcerative colitis (UC). AIMS: We investigated the correlation between CYP3A5 genetic polymorphisms and the adverse events in patients with UC. The pharmacokinetics of tacrolimus after oral administration were also analyzed. METHODS: We enrolled 29 hospitalized patients with UC received oral tacrolimus. Genotyping for CYP3A5 A6986G (rs776746) was performed using Custom TaqMan(r) SNP genotyping assays. Adverse events, concentration and dose (C/D) ratios and clinical outcomes were investigated. RESULTS: CYP3A5 expressers and non-expressers were 16 and 13, respectively. C/D ratios of CYP3A5 expressers were significantly lower compared to non-expressers. The response rate in CYP3A5 non-expressers was relatively higher in the early phase of treatment compared to expressers, but not statistically significant. The incidence of overall adverse events was significantly higher in CYP3A5 expressers than in non expressers (P=0.034, chi-squared test). In particular, the incidence of nephrotoxicity was significantly higher in CYP3A5 expressers compared to non expressers (P=0.027, chi-squared test). All of the nephrotoxicity were reversible and resolved by discontinuation or dose reduction of tacrolimus. CONCLUSION: The adverse events especially nephrotoxicity were frequently observed in CYP3A5 expressers. CYP3A5 expressers should be paid attention to the onset of nephrotoxicity. PMID- 27717795 TI - Antibiotics, intestinal dysbiosis and risk of celiac disease. PMID- 27717794 TI - Disease patterns in late-onset ulcerative colitis: Results from the IG-IBD "AGED study". AB - BACKGROUND: Late-onset UC represents an important issue for the near future, but its outcomes and relative therapeutic strategies are yet poorly studied. AIM: To better define the natural history of late-onset ulcerative colitis. METHODS: In a multicenter retrospective study, we investigated the disease presentation and course in the first 3 years in 1091 UC patients divided into 3 age-groups: diagnosis >=65years, 40-64 years, and <40years. Disease patterns, medical and surgical therapies, and risk factors for disease outcomes were analyzed. RESULTS: Chronic active or relapsing disease accounts for 44% of patients with late-onset UC. Across all age-groups, these disease patterns require 3-6 times more steroids than remitting disease, but immunomodulators and, to a lesser extent, biologics are less frequently prescribed in the elderly. Advanced age, concomitant diseases and related therapies were found to be inversely associated with the use of immunomodulators or biologics, but not with surgery. CONCLUSIONS: The conclusion that late-onset UC follows a mild course may apply only to a subset of patients. an important percentage of elderly patients present with more aggressive disease. Since steroid use and surgery rates did not differ in this subgroup, lower use of immunosuppressive therapy and biologics may reflect concerns in prescribing these therapies in the elderly. PMID- 27717796 TI - Localization of RR-1 and RR-2 cuticular proteins within the cuticle of Anopheles gambiae. AB - The largest arthropod cuticular protein family, CPR, has the Rebers and Riddiford (R&R) Consensus that in an extended form confers chitin-binding properties. Two forms of the Consensus, RR-1 and RR-2, have been recognized and initial data suggested that the RR-1 and RR-2 proteins were present in different regions within the cuticle itself. Thus, RR-2 proteins would contribute to exocuticle that becomes sclerotized, while RR-1s would be found in endocuticle that remains soft. An alternative, and more common, suggestion is that RR-1 proteins are used for soft, flexible cuticles such as intersegmental membranes, while RR-2s are associated with hard cuticle such as sclerites and head capsules. We used TEM immunogold detection to localize the position of several RR-1 and RR-2 proteins in the cuticle of Anopheles gambiae. RR-1s were localized in the procuticle of the soft intersegmental membrane except for one protein found in the endocuticle of hard cuticle. RR-2s were consistently found in hard cuticle and not in flexible cuticle. All RR-2 antibodies localized to the exocuticle and four out of six were also found in the endocuticle. Hence the location of RR-1s and RR-2s depends more on properties of individual proteins than on either hypothesis. PMID- 27717797 TI - Morphology and development of the accessory glands in various female cricket species. AB - The study presents new results with regard to the morphometric and ultrastructural development of the accessory glands in females of the three cricket species Gryllus bimaculatus, Gryllus assimilis, and Acheta domesticus. Furthermore, possible age-dependence of secretory productivity of single organs was analyzed by application of the ligature technique introduced in a previous contribution. Within the first 12 days of the adult phase, the accessory glands of all investigated cricket species exhibit a significant increase in length and width which assumes values between 50 and 100%. This gland growth is rather the result of a continuous increase in cellular volume and less that of mitotic cell propagation. In all species height and width of single gland cells increase by 60 80% within the studied time interval. These changes in morphometry are commonly accompanied by ultrastructural modifications. Total glandular secretion is subject to an increase from the 5th to the 12th day of adult age. This development corresponds well with the number of eggs contemporaneously oviposited into the substrate and thus underlines the hypothesis, according to which the main function of the secretion consists in acting as a lubricant for the facilitated transport of the oocytes through the ovipositor. PMID- 27717799 TI - Reversed T Cell Receptor Docking on a Major Histocompatibility Class I Complex Limits Involvement in the Immune Response. AB - The anti-viral T cell response is drawn from the naive T cell repertoire. During influenza infection, the CD8+ T cell response to an H-2Db-restricted nucleoprotein epitope (NP366) is characterized by preferential expansion of T cells bearing TRBV13+ T cell receptors (TCRs) and avoidance of TRBV17+ T cells, despite the latter dominating the naive precursor repertoire. We found two TRBV17+ TCRs that bound H-2Db-NP366 with a 180 degrees reversed polarity compared to the canonical TCR-pMHC-I docking. The TRBV17 beta-chain dominated the interaction and, whereas the complementarity determining region-3 (CDR3) loops exclusively mediated contacts with the MHC-I, peptide specificity was attributable to germline-encoded recognition. Nevertheless, the TRBV17+ TCR exhibited moderate affinity toward H-2Db-NP366 and was capable of signal transduction. Thus, the naive CD8+ T cell pool can comprise TCRs adopting reversed pMHC-I docking modes that limit their involvement in the immune response. PMID- 27717798 TI - Enterococcus hirae and Barnesiella intestinihominis Facilitate Cyclophosphamide Induced Therapeutic Immunomodulatory Effects. AB - The efficacy of the anti-cancer immunomodulatory agent cyclophosphamide (CTX) relies on intestinal bacteria. How and which relevant bacterial species are involved in tumor immunosurveillance, and their mechanism of action are unclear. Here, we identified two bacterial species, Enterococcus hirae and Barnesiella intestinihominis that are involved during CTX therapy. Whereas E. hirae translocated from the small intestine to secondary lymphoid organs and increased the intratumoral CD8/Treg ratio, B. intestinihominis accumulated in the colon and promoted the infiltration of IFN-gamma-producing gammadeltaT cells in cancer lesions. The immune sensor, NOD2, limited CTX-induced cancer immunosurveillance and the bioactivity of these microbes. Finally, E. hirae and B. intestinihominis specific-memory Th1 cell immune responses selectively predicted longer progression-free survival in advanced lung and ovarian cancer patients treated with chemo-immunotherapy. Altogether, E. hirae and B. intestinihominis represent valuable "oncomicrobiotics" ameliorating the efficacy of the most common alkylating immunomodulatory compound. PMID- 27717800 TI - Effect of iron deficiency anemia and iron supplementation on HbA1c levels - Implications for diagnosis of prediabetes and diabetes mellitus in Asian Indians. AB - BACKGROUND: We investigated the effect of iron deficiency anemia (IDA) on levels of glycated hemoglobin (HbA1c) and to compare its levels before and after iron supplementations. METHODS: Age and sex matched subjects were enrolled and clustered in 2 groups: IDA (n=62) and healthy controls (HC; n=60). HbA1c levels were estimated by HPLC. Hemogram were estimated by hematology analyser. Serum ferritin (ELISA) and other parameters of iron profile were measured by standard guidelines of ICSH. HbA1c values and iron studies were repeated after 3months of iron supplementation to determine the effect of iron therapy on HbA1c levels. RESULTS: Significantly higher HbA1c levels were observed in IDA subjects compared to HC (5.51+/-0.696 v/s 4.85+/-0.461%, p<0.001). A significant negative correlation was observed between HbA1c and hemoglobin, hematocrit, RBC count, MCH, MCHC and serum ferritin in IDA subjects (r=-0.632, -0.652, -0.384, -0.236, 0.192 and -0.441). Significant decline was noticed in HbA1c levels in IDA subjects after iron supplementation (5.51+/-0.696 before treatment v/s 5.044+/ 0.603 post-treatment; p<0.001). Post treatment, 70% subjects (14/20) with HbA1c in pre-diabetes range normalised to normal glucose tolerance (NGT) range and out of 6 patients with pre-treatment HbA1c in diabetes range, 5 reverted to pre diabetes range while 1 of them reverted to the NGT range. CONCLUSIONS: Caution must be exercised in interpreting the results of HbA1c in patients of IDA and iron deficiency must be corrected before diagnosing diabetes and pre-diabetes solely on the basis of HbA1c criteria. PMID- 27717801 TI - NADH dehydrogenase of Trypanosoma brucei is important for efficient acetate production in bloodstream forms. AB - In the slender bloodstream form, Trypanosoma brucei mitochondria are repressed for many functions. Multiple components of mitochondrial complex I, NADH:ubiquinone oxidoreductase, are expressed in this stage, but electron transfer through complex I is not essential. Here we investigate the role of the parasite's second NADH:ubiquinone oxidoreductase, NDH2, which is composed of a single subunit that also localizes to the mitochondrion. While inducible knockdown of NDH2 had a modest growth effect in bloodstream forms, NDH2 null mutants, as well as inducible knockdowns in a complex I deficient background, showed a greater reduction in growth. Altering the NAD+/NADH balance would affect numerous processes directly and indirectly, including acetate production. Indeed, loss of NDH2 led to reduced levels of acetate, which is required for several essential pathways in bloodstream form T. brucei and which may have contributed to the observed growth defect. In conclusion our study shows that NDH2 is important, but not essential, in proliferating bloodstream forms of T. brucei, arguing that the mitochondrial NAD+/NADH balance is important in this stage, even though the mitochondrion itself is not actively engaged in the generation of ATP. PMID- 27717802 TI - Effects of patulin and ascladiol on porcine intestinal mucosa: An ex vivo approach. AB - Patulin (PAT) is a secondary metabolite mainly produced by Aspergillus and Penicillium that is frequently found contaminating apples and rotten fruits. Patulin can be transformed in potencially less toxic compounds such as ascladiol (ASC). Toxic effects of patulin were described in rats and in in vitro models, however concerning ascladiol, data are restricted to metabolic pathways. The aim of the present study was to evaluate the effects of different concentrations of PAT (10 MUM, 30 MUM, 100 MUM) and ASC (30 MUM, 100 MUM) on intestinal tissue using the jejunal explant model. Explants from pigs were exposed for 4 h to PAT and ASC and after this period were processed for histological, morphometrical and immunohistochemical analysis. Mild histological changes were observed in jejunal explants exposed to PAT and ASC, however no significant difference in the lesional score or villi height was observed between the PAT/ASC-groups and the control. Also, explants exposed to 100 MUM of PAT showed a significant decrease in goblet cells density and a significant increase in cell apoptosis. These results indicate that high levels of patulin can induce mild toxic effects on intestinal mucosa whereas ascladiol apparently is non-toxic to intestinal tissue. PMID- 27717803 TI - Marine fatty acids aggravate hepatotoxicity of alpha-HBCD in juvenile female BALB/c mice. AB - Oily fish, a source of long-chain omega-3 polyunsaturated fatty acids (LC n-3 PUFAs), may contain persistent organic pollutants (POPs), including alpha hexabromocyclododecane (alpha-HBCD). In experimental studies, marine LC n-3 PUFAs ameliorate fatty liver development while HBCD exposure was found to cause liver fatty acid (FA) changes. The present study investigated interactions of FAs and alpha-HBCD in juvenile female BALB/c mice using a factorial design. Mice (n = 48) were exposed for 28 days to a low (100 MUg*kg body weight (BW)-1*day-1) or high dose (100 mg*kg BW-1*day-1) of alpha-HBCD in diets with or without LC n-3 PUFAs. High dose alpha-HBCD affected whole body lipid metabolism leading to changes in body weight and composition, and pathological changes in hepatic histology, which surprisingly were aggravated by dietary LC n-3 PUFAs. Hepatic FA profiling and gene expression analysis indicated that the dietary modulation of the hepatotoxic response to the high dose of alpha-HBCD was associated with differential effects on FA beta-oxidation. Our results suggest that in a juvenile mouse model, marine FAs accentuate hepatotoxic effects of high dose alpha-HBCD. This highlights that the background diet is a critical variable in the risk assessment of POPs and warrants further investigation of dietary mediated toxicity of food contaminants. PMID- 27717804 TI - Seasonal dynamics of the phytochemical constituents and bioactivities of extracts from Stenoloma chusanum (L.) Ching. AB - Stenoloma chusanum is a traditional Chinese medicinal herb with a very high total flavonoid content (TFC). The seasonal dynamics of the TFC and total phenolic content (TPC) in S. chusanum, as well as antioxidant activity, were investigated. The TFC and TPC showed clear seasonal dynamics, reaching their maxima (24.63 +/- 1.34% and 9.58 +/- 0.41%, respectively) in February. The TFC and TPC in the aerial parts of the plant were much higher than those in the subterranean parts; however, the antioxidant activities of the extracts from the subterranean parts were slightly higher than those from the aerial parts. Moreover, the extracts exhibited higher inhibition against tyrosinase than against arbutin (the positive control). The extract from S. chusanum collected in February was associated with the highest proliferation and apoptosis of K562 cells. The phytochemicals in the extract were analyzed using LC-MS, and were found to comprise of 12 flavonoids, five alkaloids, one sesquiterpenoid and one phenypropanoid. In conclusion, S. chusanum exhibits multiple bioactivities; these results could contribute to the therapeutic application of the plants in indigenous medicine. PMID- 27717805 TI - The Na+/HCO3- co-transporter is protective during ischemia in astrocytes. AB - The sodium bicarbonate co-transporter (NBC) is the major bicarbonate-dependent acid-base transporter in mammalian astrocytes and has been implicated in ischemic brain injury. A malfunction of astrocytes could have great impact on the outcome of stroke due to their participation in the formation of blood-brain barrier, synaptic transmission, and electrolyte balance in the human brain. Nevertheless, the role of NBC in the ischemic astrocyte death has not been well understood. In this work, we obtained skin biopsies from healthy human subjects and had their fibroblasts grown in culture and reprogrammed into human-induced pluripotent stem cells (hiPSCs). These hiPSCs were further differentiated into neuroprogenitor cells (NPCs) and then into human astrocytes. These astrocytes express GFAP and S100beta and readily propagate calcium waves upon mechanical stimulation. Using pH-sensitive dye BCECF [2',7'-bis-(carboxyethyl)-5-(and-6)-carboxyfluorescein] and qPCR technique, we have confirmed that these astrocytes express functional NBC including electrogenic NBC (NBCe). In addition, astrocytes exposed to an ischemic solution (IS) that mimics the ischemic penumbral environment enhanced both mRNA and protein expression level of NBCe1 in astrocytes. Using IS and a generic NBC blocker S0859, we have studied the involvement of NBC in IS-induced human astrocytes death. Our results show that a 30MUM S0859 induced a 97.5+/-1.6% (n=10) cell death in IS-treated astrocytes, which is significantly higher than 43.6+/-4.5%, (n=10) in the control group treated with IS alone. In summary, a NBC blocker exaggerates IS-induced cell death, suggesting that NBC activity is essential for astrocyte survival when exposed to ischemic penumbral environment. PMID- 27717806 TI - Convergent transcriptomics and proteomics of environmental enrichment and cocaine identifies novel therapeutic strategies for addiction. AB - Transcriptomic and proteomic approaches have separately proven effective at identifying novel mechanisms affecting addiction-related behavior; however, it is difficult to prioritize the many promising leads from each approach. A convergent secondary analysis of proteomic and transcriptomic results can glean additional information to help prioritize promising leads. The current study is a secondary analysis of the convergence of recently published separate transcriptomic and proteomic analyses of nucleus accumbens (NAc) tissue from rats subjected to environmental enrichment vs. isolation and cocaine self-administration vs. saline. Multiple bioinformatics approaches (e.g. Gene Ontology (GO) analysis, Ingenuity Pathway Analysis (IPA), and Gene Set Enrichment Analysis (GSEA)) were used to interrogate these rich data sets. Although there was little correspondence between mRNA vs. protein at the individual target level, good correspondence was found at the level of gene/protein sets, particularly for the environmental enrichment manipulation. These data identify gene sets where there is a positive relationship between changes in mRNA and protein (e.g. glycolysis, ATP synthesis, translation elongation factor activity, etc.) and gene sets where there is an inverse relationship (e.g. ribosomes, Rho GTPase signaling, protein ubiquitination, etc.). Overall environmental enrichment produced better correspondence than cocaine self-administration. The individual targets contributing to mRNA and protein effects were largely not overlapping. As a whole, these results confirm that robust transcriptomic and proteomic data sets can provide similar results at the gene/protein set level even when there is little correspondence at the individual target level and little overlap in the targets contributing to the effects. PMID- 27717808 TI - Alterations in AMPA receptor subunit expression in cortical inhibitory interneurons in the epileptic stargazer mutant mouse. AB - Absence seizures arise from disturbances within the corticothalamocortical network, however the precise cellular and molecular mechanisms underlying seizure generation arising from different genetic backgrounds are not fully understood. While recent experimental evidence suggests that changes in inhibitory microcircuits in the cortex may contribute to generation of the hallmark spike wave discharges, it is still unclear if altered cortical inhibition is a result of interneuron dysfunction due to compromised glutamatergic excitation and/or changes in cortical interneuron number. The stargazer mouse model of absence epilepsy presents with a genetic deficit in stargazin, which is predominantly expressed in cortical parvalbumin-positive (PV+) interneurons, and involved in the trafficking of glutamatergic AMPA receptors. Hence, in this study we examine changes in (1) the subunit-specific expression of AMPA receptors which could potentially result in a loss of excitation onto cortical PV+ interneurons, and (2) PV+ neuron density that could additionally impair cortical inhibition. Using Western blot analysis we found subunit-specific alterations in AMPA receptor expression in the stargazer somatosensory cortex. Further analysis using confocal fluorescence microscopy revealed that although there are no changes in cortical PV+ interneuron number, there is a predominant loss of GluA1 and 4 containing AMPA receptors in PV+ neurons in stargazers compared to non-epileptic controls. Taken together, these data suggest that the loss of AMPA receptors in PV+ neurons could impair their feed-forward inhibitory output, ultimately altering cortical network oscillations, and contribute to seizure generation in stargazers. As such the feed-forward inhibitory interneurons could be potential targets for future therapeutic intervention for some absence epilepsy patients. PMID- 27717809 TI - Dysregulation of the endocannabinoid signaling system in the cerebellum and brainstem in a transgenic mouse model of spinocerebellar ataxia type-3. AB - Spinocerebellar ataxia type-3 (SCA-3) is a rare disease but it is the most frequent type within the autosomal dominant inherited ataxias. The disease lacks an effective treatment to alleviate major symptoms and to modify disease progression. Our recent findings that endocannabinoid receptors and enzymes are significantly altered in the post-mortem cerebellum of patients affected by autosomal-dominant hereditary ataxias suggest that targeting the endocannabinoid signaling system may be a promising therapeutic option. Our goal was to investigate the status of the endocannabinoid signaling system in a transgenic mouse model of SCA-3, in the two CNS structures most affected in this disease - cerebellum and brainstem. These animals exhibited progressive motor incoordination, imbalance, abnormal gait, muscle weakness, and dystonia, in parallel to reduced in vivo brain glucose metabolism, deterioration of specific neuron subsets located in the dentate nucleus and pontine nuclei, small changes in microglial morphology, and reduction in glial glutamate transporters. Concerning the endocannabinoid signaling, our data indicated no changes in CB2 receptors. By contrast, CB1 receptors increased in the Purkinje cell layer, in particular in terminals of basket cells, but they were reduced in the dentate nucleus. We also measured the levels of endocannabinoid lipids and found reductions in anandamide and oleoylethanolamide in the brainstem. These changes correlated with an increase in the FAAH enzyme in the brainstem, which also occurred in some cerebellar areas, whereas other endocannabinoid-related enzymes were not altered. Collectively, our results in SCA-3 mutant mice confirm a possible dysregulation in the endocannabinoid system in the most important brain structures affected in this type of ataxia, suggesting that a pharmacological manipulation addressed to correct these changes could be a promising option in SCA-3. PMID- 27717807 TI - Sex differences in astrocyte and microglia responses immediately following middle cerebral artery occlusion in adult mice. AB - Epidemiological studies report that infarct size is decreased and stroke outcomes are improved in young females when compared to males. However, mechanistic insight is lacking. We posit that sex-specific differences in glial cell functions occurring immediately after ischemic stroke are a source of dichotomous outcomes. In this study we assessed astrocyte Ca2+ dynamics, aquaporin 4 (AQP4) polarity, S100beta expression pattern, as well as, microglia morphology and phagocytic marker CD11b in male and female mice following 60min of middle cerebral artery (MCA) occlusion. We reveal sex differences in the frequency of intracellular astrocyte Ca2+ elevations (F(1,86)=8.19, P=0.005) and microglia volume (F(1,40)=12.47, P=0.009) immediately following MCA occlusion in acute brain slices. Measured in fixed tissue, AQP4 polarity was disrupted (F(5,86)=3.30, P=0.009) and the area of non-S100beta immunoreactivity increased in ipsilateral brain regions after 60min of MCA occlusion (F(5,86)=4.72, P=0.007). However, astrocyte changes were robust in male mice when compared to females. Additional sex differences were discovered regarding microglia phagocytic receptor CD11b. In sham mice, constitutively high CD11b immunofluorescence was observed in females when compared to males (P=0.03). When compared to sham, only male mice exhibited an increase in CD11b immunoreactivity after MCA occlusion (P=0.006). We posit that a sex difference in the presence of constitutive CD11b has a role in determining male and female microglia phagocytic responses to ischemia. Taken together, these findings are critical to understanding potential sex differences in glial physiology as well as stroke pathobiology which are foundational for the development of future sex-specific stroke therapies. PMID- 27717810 TI - Activation of state-regulating neurochemical systems in newborn and embryonic chicks. AB - Coordinated activity in different sets of widely-projecting neurochemical systems characterize waking (W) and sleep (S). How and when this coordination is achieved during development is not known. We used embryos and newborns of a precocial bird species (chickens) to assess developmental activation in different neurochemical systems using cFos expression, which has been extensively employed to examine cellular activation during S and W in adult mammals. Similarly to adult mammals, newborn awake chicks showed significantly higher cFos expression in W-active hypocretin/orexin (H/O), serotonergic Dorsal Raphe, noradrenergic Locus Coeruleus and cholinergic Laterodorsal and Pedunculopontine Tegmental (Ch-LDT/PT) neurons when compared to sleeping chicks. cFos expression was significantly correlated both between these systems, and with the amount of W. S-active melanin concentrating hormone (MCH) neurons showed very low cFos expression with no difference between sleeping and awake chicks, possibly due to the very short duration of S episodes. In embryonic chicks, cFos expression was low or absent across all five systems at embryonic day (E) 12. Unexpectedly, a strong activation was seen at E16 in H/O neurons. The highest activation of Ch-LDT/PT (also S-active) and MCH neurons was seen at E20. These data suggest that maturation of arousal systems is achieved soon after hatching, while S-control networks are active in late chick embryos. PMID- 27717811 TI - Structure and functions of the chaperone-like p97/CDC48 in plants. AB - BACKGROUND: The chaperone-like p97 is a member of the AAA+ ATPase enzyme family that contributes to numerous cellular activities. P97 has been broadly studied in mammals (VCP/p97) and yeasts (CDC48: Cell Division Cycle 48/p97) and numerous investigations highlighted that this protein is post-translationally regulated, is structured in homohexamer and interacts with partners and cofactors that direct it to distinct cellular signalization pathway including protein quality control and degradation, cell cycle regulation, genome stability, vesicular trafficking, autophagy and immunity. SCOPE OF REVIEW: p97 is also conserved in plants (CDC48) but its functions are less understood. In the present review we intended to present the state of the art of the structure, regulation and functions of CDC48 in plants. MAJOR CONCLUSIONS: Evidence accumulated underline that CDC48 plays a crucial role in development, cell cycle regulation and protein turnover in plants. Furthermore, its involvement in plant immunity has recently emerged and first interacting partners have been identified, shedding light on its putative cellular activities. GENERAL SIGNIFICANCE: Identification of emerging functions of CDC48 in plants opens new roads of research in immunity and provides new insights into the mechanisms of protein quality control. PMID- 27717812 TI - Behavioural endophenotypes in mice lacking the auxiliary GABAB receptor subunit KCTD16. AB - Gamma-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the brain and is implicated in the pathophysiology of a number of neuropsychiatric disorders. The GABAB receptors are G-protein coupled receptors consisting of principle subunits and auxiliary potassium channel tetramerization domain (KCTD) subunits. The KCTD subunits 8, 12, 12b and 16 are cytosolic proteins that determine the kinetics of the GABAB receptor response. Previously, we demonstrated that Kctd12 null mutant mice (Kctd12-/-) exhibit increased auditory fear learning and that Kctd12+/- mice show altered circadian activity, as well as increased intrinsic excitability in hippocampal pyramidal neurons. KCTD16 has been demonstrated to influence neuronal excitability by regulating GABAB receptor mediated gating of postsynaptic ion channels. In the present study we investigated for behavioural endophenotypes in Kctd16-/- and Kctd16+/- mice. Compared with wild-type (WT) littermates, auditory and contextual fear conditioning were normal in both Kctd16-/- and Kctd16+/- mice. When fear memory was tested on the following day, Kctd16-/- mice exhibited less extinction of auditory fear memory relative to WT and Kctd16+/- mice, as well as more contextual fear memory relative to WT and, in particular, Kctd16+/- mice. Relative to WT, both Kctd16+/- and Kctd16-/- mice exhibited normal circadian activity. This study adds to the evidence that auxillary KCTD subunits of GABAB receptors contribute to the regulation of behaviours that could constitute endophenotypes for hyper-reactivity to aversive stimuli in neuropsychiatric disorders. PMID- 27717814 TI - Differential associations between behavioral and cortisol responses to a stressor in securely versus insecurely attached infants. AB - In this study we examined whether securely versus insecurely attached infants use different regulatory behaviors in absence of their mother and whether these regulatory behaviors are differentially associated with physiological stress responses in secure versus insecure infants. Participants were 193 one-year-olds and their mothers. During three 3-min episodes of separation from the mother in the Strange Situation Procedure (SSP) [1], the following infant regulatory behaviors were observed: crying, fussing, self-soothing, manipulation of toys, and manipulation of the door. Salivary cortisol was measured at baseline and 25, 40, and 60min after the SSP to measure reactivity and recovery. Additionally, infants were classified as securely or insecurely attached to their mothers. During the mother's absence, secure infants engaged more in manipulation of the door than insecure infants. Furthermore, in insecure (but not secure) infants less fussing was associated with higher cortisol reactivity, while in secure (but not insecure) infants more self-soothing was associated with higher cortisol reactivity. In total, 29% of the variance in cortisol reactivity was explained by infant regulatory behaviors in the mother's absence. Cortisol recovery was not predicted by infant regulatory behaviors in the mother's absence. To conclude, the results show differential associations between behavioral and cortisol responses to a stressor in secure versus insecure infants. This might indicate that secure and insecure infants apply different behavioral regulatory strategies when physiologically stressed. PMID- 27717813 TI - Human adipose-derived stem cells ameliorate repetitive behavior, social deficit and anxiety in a VPA-induced autism mouse model. AB - Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by impairments in social interaction and communication, and patients often display co-occurring repetitive behaviors. Although the global prevalence of ASD has increased over time, the etiology and treatments for ASD are poorly understood. Recently, some researchers have suggested that stem cells have therapeutic potential for ASD. Thus, in the present study, we investigated the therapeutic effects of human adipose-derived stem cells (hASCs), a kind of autologous mesenchymal stem cells (MSCs) isolated from adipose tissue, on valproic acid (VPA)-induced autism model mice. Human ASCs were injected into the neonatal pups (P2 or P3) intraventricularly and then we evaluated major behavior symptoms of ASD. VPA-treated mice showed increased repetitive behaviors, decreased social interactions and increased anxiety but these autistic behaviors were ameliorated through transplantation of hASCs. In addition, hASCs transplantation restored the alteration of phosphatase and tensin homolog (PTEN) expression and p-AKT/AKT ratio in the brains of VPA-induced ASD model mice. The decreased level of vascular endothelial growth factor (VEGF) and interleukin 10 (IL-10) by VPA were rescued in the brains of the hASC-injected VPA mice. With these results, we experimentally found hASCs' therapeutic effects on autistic phenotypes in a ASD model mice for the first time. This animal model system can be used to elucidate further mechanisms of therapeutic effects of hASCs in ASD. PMID- 27717815 TI - Reorganization of motor cortex and impairment of motor performance induced by hindlimb unloading are partially reversed by cortical IGF-1 administration. AB - Immobilization, bed rest, or sedentary lifestyle, are known to induce a profound impairment in sensorimotor performance. These alterations are due to a combination of peripheral and central factors. Previous data conducted on a rat model of disuse (hindlimb unloading, HU) have shown a profound reorganization of motor cortex and an impairment of motor performance. Recently, our interest was turned towards the role of insulin-like growth factor 1 (IGF-1) in cerebral plasticity since this growth factor is considered as the mediator of beneficial effects of exercise on the central nervous system, and its cortical level is decreased after a 14-day period of HU. In the present study, we attempted to determine whether a chronic subdural administration of IGF-1 in HU rats could prevent deleterious effects of HU on the motor cortex and on motor activity. We demonstrated that HU induces a shrinkage of hindlimb cortical representation and an increase in current threshold to elicit a movement. Administration of IGF-1 in HU rats partially reversed these changes. The functional evaluation revealed that IGF-1 prevents the decrease in spontaneous activity found in HU rats and the changes in hip kinematics during overground locomotion, but had no effect of challenged locomotion (ladder rung walking test). Taken together, these data clearly indicate the implication of IGF-1 in cortical plastic mechanisms and in behavioral alteration induced by a decreased in sensorimotor activity. PMID- 27717816 TI - Extending the Arc of Rotation of the Pectoralis Major Myocutaneous Flap for Orofacial Reconstruction via a Modified Subclavicular Route Through the Clavipectoral Fascia. AB - PURPOSE: Drawbacks of the conventional supraclavicular overlay of the pectoralis major myocutaneous flap (PMMF) include the resultant unesthetic cervical bulge and the limited cephalad extension that limits its use to mandibular or cervical defects. This study discusses the technique and comparative advantages of a more esthetic subclavicular route through the clavipectoral fascia that allows an increased arc of rotation to reconstruct orofacial defects. MATERIALS AND METHODS: Patients with orofacial defects that were reconstructed with a PMMF through the modified subclavicular route were included in this retrospective cohort study, which aimed to compare the gain in extension accorded through the modified subclavicular tunnel over an initial conventional supraclavicular overlay. Outcome variables included the dimension of each skin paddle and the cross-sectional area of each flap. Other variables, such as age and gender, also were investigated. Complications that arose from this technique were statistically compared with these variables and with those from previously reported studies. All data analyses were performed using Pearson chi2 and correlation tests. RESULTS: Twelve patients (7 women and 5 men) who underwent a primary reconstruction with the PMMF during a 1-year period from November 2010 to November 2011 were selected for this study. All 12 flaps survived; 3 developed minor postoperative complications that resolved within the 3-month review period. A PMMF with an average dimension of 12.75 * 6.0 * 3.725 cm and cross-sectional area of 20.65 cm2 could pass through this modified tunnel, achieving an average gain in extension of 3.2 cm that enabled the reconstruction of defects up to and above the level of the oral commissure. Apart from skin paddle dimension, all other variables were not found to be statistically related to the extension accorded by the modified route. Complications that occurred appeared to be related only to the cross-sectional area of the flap. CONCLUSION: The increased cephalad extension afforded by this modified subclavicular route through the clavipectoral fascia permitted the reconstruction of orofacial defects that would otherwise have required free vascularized grafts with microvascular surgery and avoided the unesthetic cervical bulge from conventional supraclavicular overlays of the PMMF. PMID- 27717817 TI - An Overview of Infections Associated With Soft Tissue Facial Fillers: Identification, Prevention, and Treatment. AB - PURPOSE: The purpose of this study was to provide an overview of infections associated with facial soft tissue fillers. MATERIALS AND METHODS: A literature review was performed which evaluated infections associated with facial soft tissue fillers. RESULTS: Infection rates with soft tissue fillers are low and are estimated at 0.04 to 0.2%. Most of these infections arise when skin contaminants infiltrate the injection site at the time of injection. These infections can occur early, up to several days after treatment, or delayed, occurring weeks to years after treatment. Reactions vary based on the filler absorbability and duration. Early recognition and treatment are important factors in managing our cosmetic surgery patients. CONCLUSION: Although facial fillers are safe and predictable, infections can still occur. Oral and maxillofacial surgeons need to be able to prevent, recognize, and properly manage infections related to these popular injections. PMID- 27717819 TI - Concomitant Suppurative Parotitis and Condylar Osteomyelitis. AB - Parotitis is a common occurrence in the immunocompromised, dehydrated, and malnourished patient as a result of dysfunctional ductal and parotid cells. Inflammation can be acute or chronic based on clinical history, and it can be suppurative based on the presence of micro or macro abscess formation within the substance of the gland. This report presents a case of concomitant condylar osteomyelitis and chronic suppurative parotitis in the setting of previous methicillin-susceptible Staphylococcus aureus foot infection. Ultimately, resection of osteomyelitis, drainage of parotid infection, and intravenous antibiotic therapy led to full resolution of the infection and symptoms. The final pathology of osteomyelitis of the temporomandibular joint and methicillin resistant S aureus infection is an unusual consequence of chronic parotitis. The patient was restored with a total joint replacement approximately 3 months after resection with no recurrence of infection after 24 months. PMID- 27717818 TI - Craniofacial Resection and Reconstruction in Patients With Recurrent Cancer Involving the Craniomaxillofacial Region. AB - PURPOSE: Head and neck tumors that involve the craniomaxillofacial region are classified as stage IVb disease and are clinically challenging. In this study, the outcomes of craniofacial resection and craniofacial reconstruction in patients with recurrent malignant tumors involving the craniomaxillofacial region were evaluated. PATIENTS AND METHODS: This retrospective observational study was conducted from January 2008 to August 2015. Data collected for each patient included age, gender, tumor site, initial treatment, craniofacial resection, reconstruction flaps and complications after craniofacial resection, adjuvant treatment, and reported outcomes of craniofacial resection and craniofacial reconstruction. The chi2 test in SPSS was used to analyze the data. RESULTS: Twenty-four patients with recurrent malignant tumors involving the craniomaxillofacial region were identified who had undergone craniofacial resection at the Center of Craniomaxillofacial Surgery of Sun Yat-sen University (Guangzhou, Guangdong, China). The study population was comprised of 24 patients (15 men and 9 women; age range, 21 to 73 yr) with recurrent tumors (58.3% with squamous cell carcinoma [SCC], 41.7% with sarcoma [SA]) involving the craniomaxillofacial region who underwent craniofacial resection. Craniofacial resection consisted of orbital exenteration and maxillotomy; anterior skull base surgery, facial resection, and mandibulotomy; or ipsilateral radical neck dissection. The resultant craniomaxillofacial defects were reconstructed using extended vertical lower trapezius island myocutaneous flaps (TIMFs), temporalis myofascial flaps, or submental flaps. All patients with recurrent malignant tumor involving the craniomaxillofacial region underwent gross total resection of the tumor; 22 patients underwent craniofacial reconstruction. There were no major surgical complications. Minor flap failure and wound dehiscence in the donor site occurred in 4 patients. The follow-up period ranged from 8 to 36 months. Seven patients in the SCC group and 7 in the SA group were alive with no evidence of disease (AND), 3 in the SCC group and 2 in the SA group were alive with disease (AWD), and 4 in the SCC and 1 in the SA group died of the disease (DOD) after local recurrence or distant metastases at 8 to 18 months. There were no statistical differences among the AND, AWD, and DOD groups. CONCLUSIONS: Craniofacial resection remains an effective salvage treatment for patients with recurrent SCC and SA involving the craniomaxillofacial region. The extended vertical lower TIMF is a large, simple, and reliable flap for reconstructing major defects after a craniofacial resection. PMID- 27717820 TI - Discovery of an artificial peptide agonist to the fibroblast growth factor receptor 1c/betaKlotho complex from random peptide T7 phage display. AB - Fibroblast growth factor receptor-1c (FGFR1c)/betaKlotho (KLB) complex is a receptor of fibroblast growth factor 21 (FGF21). Pharmacologically, FGF21 shows anti-obesity and anti-diabetic effects upon peripheral administration. Here, we report the development of an artificial peptide agonist to the FGFR1c/KLB heterodimer complex. The peptide, F91-8A07 (LPGRTCREYPDLWWVRCY), was discovered from random peptide T7 phage display and selectively bound to the FGFR1c/KLB complex, but not to FGFR1c and KLB individually. After subsequent peptide dimerization using a short polyethyleneglycol (PEG) linker, the dimeric F91-8A07 peptide showed higher potent agonist activity than that of FGF21 in cultured primary human adipocytes. Moreover, the dimeric peptide led to an expression of the early growth response protein-1 (Egr-1) mRNA in vivo, which is a target gene of FGFR1c. To the best of our knowledge, this is the first report of a FGFR1c/KLB complex-selective artificial peptide agonist. PMID- 27717821 TI - miR-144-3p serves as a tumor suppressor for renal cell carcinoma and inhibits its invasion and metastasis by targeting MAP3K8. AB - MicroRNAs (miRNAs) are important regulators involved in various cancers, including renal cell carcinoma (RCC). The role of the miRNAs involved in RCC progress and metastasis is largely unknown. Here, miRNA microarray analysis was performed to screen the significant miRNAs involved in RCC progress, and miR-144 3p was chosen for further study. We found that the expression of miR-144-3p was significantly lower in RCC specimens and cell lines. In addition, low expression level of miR-144-3p is correlated with tumor progression and poor survival in RCC patients. Based on in vitro assays, we found that miR-144-3p significantly inhibit cancer cell proliferation and progression. Furthermore, function studies revealed that miR-144-3p was significantly correlated with the metastasis potential by affecting the epithelial-mesenchymal transition (EMT). Moreover, Mitogen-activated protein kinase 8 (MAP3K8) is direct target of miR-144-3p, while the expression levels of MAP3K8 were inversely correlated with the expression levels of miR-144-3p in RCC tissues. Overall, our findings demonstrate that miR 144-3p targeted the MAP3K8 pathway to reduce tumor cells proliferation and metastasis in RCC, suggesting that this axis may provide a novel therapeutic target for RCC therapy. PMID- 27717822 TI - Inhibiting c-Jun N-terminal kinase partially attenuates caffeine-dependent cell death without alleviating the caffeine-induced reduction in mitochondrial respiration in C2C12 skeletal myotubes. AB - Caffeine is a widely consumed stimulant that has previously been shown to promote cytotoxic stress and even cell death in numerous mammalian cell lines. Thus far there is little information available regarding the toxicity of caffeine in skeletal muscle cells. Our preliminary data revealed that treating C2C12 myotubes with 5 mM caffeine for 6 h increased nuclear fragmentation and reduced basal and maximal oxygen consumption rate (OCR) in skeletal myotubes. The purpose of this study was to further elucidate the pathways by which caffeine increased cell death and reduced mitochondrial respiration. We specifically examined the role of c-Jun N-terminal kinase (JNK), which has previously been shown to simultaneously increase caspase-dependent cell death and reduce mitochondrial respiration in other mammalian cell lines. We found that caffeine promoted a dose-dependent increase in cell death in multinucleated myotubes but did not in mononucleated myoblasts. The addition of 10 MUM Z-DEVD-FMK, a specific inhibitor of executioner caspases, completely inhibited caffeine-dependent cell death. Further, the addition of 400 MUM dantrolene, a specific ryanodine receptor (RYR) inhibitor, prevented the caffeine-dependent increase in cell death and the reduction in basal and maximal OCR. We also discovered that caffeine treatment significantly increased the phosphorylation of JNK and that the addition of 30 MUM SP600125 (JNKi), a specific JNK inhibitor, partially attenuated caffeine-induced cell death without preventing the caffeine-dependent reduction in basal and maximal OCR. Our results suggest that JNK partially mediates the increase in caspase dependent cell death but does not contribute to reduced mitochondrial respiration in caffeine-treated skeletal muscle cells. We conclude that caffeine increased cell death and reduced mitochondrial respiration in a calcium-dependent manner by activating the RYR and promoting reticular calcium release. PMID- 27717823 TI - Plexin A1 signaling confers malignant phenotypes in lung cancer cells. AB - Aberrant changes to several signaling pathways because of genetic mutations or increased cytokine production are critical for tumor cells to become malignant. Semaphorin 3A (SEMA3A) acts as a bivalent factor that suppresses or promotes tumor development in different pathological backgrounds. Previously, we showed that SEMA3A positively regulated the proliferative and glycolytic activities of mouse-derived Lewis lung carcinoma (LLC) cells. Plexins A1-A4 (PLXNA1-PLXNA4) are SEMA3A receptors; however, it is not known which subtype is critical for oncogenic SEMA3A signaling. We used LLC cells to investigate the role of PLXNA1 in oncogenic SEMA3A signaling. Using short hairpin RNA-mediated knockdown, we investigated the effects of constitutive inhibition of Plxna1 on cell proliferation, metabolic dependency, and epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) sensitivity. We found that Plxna1 knockdown did not affect apoptosis but resulted in decreased cell proliferation and reductions in mRNA expression levels of proliferation-marker genes, such as Ccnd1, Pcna, and Myc. In addition, we found decreased mRNA expression levels of glycolysis-associated genes, such as Pkm2 and Ldha, and decreased lactate production. In contrast, we found no changes in the mRNA expression levels of oxidative phosphorylation-associated genes, such as Cycs, Cox5a, and Atp5g1. We found that Plxna1 knockdown conferred resistance to glucose starvation but increased cytotoxicity to oligomycin. Plxna1 or Sema3a knockdown caused an increased sensitivity to the EGFR-TKIs gefitinib and erlotinib, in Lewis lung carcinoma (LLC) cells. These findings demonstrate that PLXNA1 mediates the acquisition of malignant phenotypes induced by autocrine SEMA3A signaling. PMID- 27717825 TI - alphaMSH promotes preadipocyte proliferation by alleviating ER stress-induced leptin resistance and by activating Notch1 signal in mice. AB - Alpha-melanocyte stimulating hormone (alphaMSH) has an important role in the regulation of body weight and energy expenditure. Nevertheless, the molecular mechanisms of circulating alphaMSH on preadipocyte proliferation remain elusive. We found alphaMSH was reduced by high fat diet (HFD) while leptin was elevated in adipose tissue. Leptin resistance and endoplasmic reticulum (ER) stress of adipose tissue were increased in obese mice. alphaMSH increased leptin sensitivity and alleviated ER stress along with increased p-STAT3 level and reduced SOCS3, GRP78, CHOP, ATF4, p27 and p53 levels. alphaMSH and leptin co treatment alleviated ER stress through decreasing the levels of GRP78 and CHOP. Tunicamycin (TM) or thapsigargin (Tg) induced ER stress blunted leptin sensitivity and inhibited preadipocyte proliferation. alphaMSH and leptin co treatment increased the cell number, augmented G1-S transition, elevated leptin sensitivity, and reduced ER stress; it also activated Notch1 signal and stimulated preadipocyte proliferation, whereas ER stress marker genes were decreased during this process. However, the effects of alphaMSH and leptin were blocked by the specific inhibitor of Notch1 signal. In summary, our data revealed alphaMSH enhanced leptin sensitivity and preadipocyte proliferation, meanwhile inhibited ER stress of preadipocytes by activating Notch1 signal. PMID- 27717824 TI - MyD88 contributes to neuroinflammatory responses induced by cerebral ischemia/reperfusion in mice. AB - Myeloid differentiation primary-response protein-88 (MyD88) is one of adaptor proteins mediating Toll-like receptors (TLRs) signaling. Activation of MyD88 results in the activation of nuclear factor kappa B (NFkappaB) and the increase of inflammatory responses. Evidences have demonstrated that TLRs signaling contributes to cerebral ischemia/reperfusion (I/R) injury. However, the role of MyD88 in this mechanism of action is disputed and needs to be clarified. In the present study, in a mouse model of cerebral I/R, we examined the activities of NFkappaB and interferon factor-3 (IRF3), and the inflammatory responses in ischemic brain tissue using ELISA, Western blots, and real-time PCR. Neurological function and cerebral infarct size were also evaluated 24 h after cerebral I/R. Our results showed that NFkappaB activity increased in ischemic brains, but IRF3 was not activated after cerebral I/R, in wild-type (WT) mice. MyD88 deficit inhibited the activation of NFkappaB, and the expression of interleukin-1beta (IL 1beta), IL-6, Beclin-1 (BECN1), pellino-1, and cyclooxygenase-2 (COX-2) increased by cerebral I/R compared with WT mice. Interestingly, the expression of interferon Beta 1 (INFB1) and vascular endothelial growth factor (VEGF) increased in MyD88 KO mice. Unexpectedly, although the neurological function improved in the MyD88 knockout (KO) mice, the deficit of MyD88 failed to reduce cerebral infarct size compared to WT mice. We concluded that MyD88-dependent signaling contributes to the inflammatory responses induced by cerebral I/R. MyD88 deficit may inhibit the increased inflammatory response and increase neuroprotective signaling. PMID- 27717826 TI - Treadmill exercise induces selective changes in hippocampal histone acetylation during the aging process in rats. AB - Physical exercise and the aging process have been shown to induce opposite effects on epigenetic marks, such as histone acetylation. The impact of exercise on hippocampal histone acetylation on specific lysine residues, especially during the aging process, is rarely studied. The aim of this study was to investigate the effect of treadmill exercise (20min/day during 2 weeks) on H3K9, H4K5 and H4K12 acetylation levels in hippocampi of young adult and aged rats. Male Wistar rats aged 3 or 20-21 months were assigned to sedentary and exercise groups. Single-trial step-down inhibitory avoidance conditioning was employed as an aversive memory paradigm. Hippocampal H3K9, H4K5 and H4K12 acetylation was determined by Western blotting. The daily moderate exercise protocol improved the aversive memory performance and increased hipocampal H4K12 acetylation levels in both tested ages. Exercise was also able to increase H3K9 acetylation levels in aged rats. An age-related decline in memory performance was observed, without any effect of the aging process on histone acetylation state. Our data suggest that treadmill exercise can impact hippocampal the histone acetylation profile in an age- and lysine-dependent manner. In addition, higher hippocampal H4K12 acetylation levels at both ages may be related to improvement of aversive memory performance. PMID- 27717827 TI - Low d-serine levels in schizophrenia: A systematic review and meta-analysis. AB - An increasing amount of evidence indicates that d-serine, a potent and selective endogenous coagonist of the N-methyl-d-aspartate receptor (NMDAR), is efficacious in the treatment of schizophrenia. Although the therapeutic efficacy of d-serine supplementation is based on the d-serine deficit and NMDAR hypofunction hypothesis, it has not been confirmed whether d-serine levels are decreased in patients with schizophrenia compared to healthy controls. We searched the following electronic databases: Embase, Ovid Medline, and the Cochrane Library. A total of 20 studies were included in our meta-analysis. Serum d-serine levels were significantly decreased in patients with schizophrenia (standardized mean difference (SMD)=-1.008, 95% CI=-1.827 to -0.190). In the meta-regression analysis, male gender was positively correlated with serum d-serine levels (coefficient=0.190, 95% CI=0.070 to 0.311). d-Serine therapy combined with antipsychotics significantly improved negative (SMD=-0.319, 95% CI=-0.576 to 0.061) and positive (SMD=-0.211, 95% CI=-0.413 to -0.009) symptoms in patients with schizophrenia. Our results suggest that decreased d-serine availability may justify combining d-serine therapy with antipsychotics in patients with schizophrenia. However, clinical methodological heterogeneity across studies should be considered a major limitation of this analysis. PMID- 27717828 TI - Spinal CXCL5 contributes to nerve injury-induced neuropathic pain via modulating GSK-3beta phosphorylation and activity in rats. AB - BACKGROUND: Neuroinflammation is identified to be crucial in the development of neuropathic pain, whereas definite molecular mechanisms remain obscure. Recently, chemokine CXCL5 is manifested to participate in the inflammatory process of central nervous system, however, little is known about the potential effect of spinal CXCL5 on pathogenesis of pain. This study investigated whether and how CXCL5 and its receptor CXCR2 regulated neuropathic pain in a rat model of chronic constriction injury (CCI) of the sciatic nerves. METHODS: Recombinant CXCL5, a neutralizing antibody against CXCL5, selective CXCR2 antagonist SB225002 and GSK 3beta inhibitor TDZD-8 were injected intrathecally. PWT and PWL were documented to assess mechanical allodynia and thermal hyperalgesia. Simultaneously, levels of CXCL5 and CXCR2 in spinal dorsal horn were measured by RT-qPCR after nociceptive testing. Western blot was utilized to evaluate spinal GSK-3beta expression and phosphorylation. RESULTS: We found that CCI engendered rapid and long-lasting mechanical allodynia and thermal hyperalgesia, which was accompanied by dramatical rise of spinal CXCL5 and CXCR2 expression. CCI also caused an increase of pGSK-3beta (Tyr216) and a decrease of pGSK-3beta (Ser9) without affecting total protein level of GSK-3beta. Moreover, spinal blockage of CXCL5/CXCR2 pathway attenuated neuropathic pain and inhibited the enhancement of GSK-3beta activity. Also, intrathecal delivery of exogenous CXCL5 dose dependently induced nociceptive hypersensitivity in naive rats, which was prevented by the supplemental addition of TDZD-8. CONCLUSION: These present findings indicate that up-regulation of spinal CXCL5 and CXCR2 is involved in neuropathic pain after nerve injury, through regulating GSK-3beta activity in rats. PMID- 27717829 TI - Effects of (-)-sesamin on chronic stress-induced memory deficits in mice. AB - This study investigated the effects of (-)-sesamin on memory deficits induced by chronic electric footshock (EF)-induced stress in mice. Mice were treated with ( )-sesamin (25 and 50mg/kg, p.o., daily for 21day) prior to chronic EF stress (0.6mA, 1s every 5s for 3min, daily for 21day). Transfer retention latencies in the elevated plus maze test and N-methyl-d-aspartate (NMDA) receptor (type 1) phosphorylation in the hippocampus increased with chronic EF stress, and they were reduced by treatment with (-)-sesamin at both doses. Phosphorylation of extracellular signal-regulated kinase (ERK1/2) and cyclic AMP-responsive element binding protein (CREB), which were reduced by chronic EF stress, were increased by treatment with (-)-sesamin. Retention latencies in the passive avoidance test and dopamine levels in the substantia nigra-striatum were also reduced by chronic EF stress, and similarly recovered with (-)-sesamin treatment. These results suggest that (-)-sesamin ameliorates the effects of chronic EF stress-induced spatial and habit learning memory deficits by modulating both NMDA receptor and dopaminergic neuronal systems. PMID- 27717830 TI - Duration of untreated illness as a key to early intervention in schizophrenia: A review. AB - The first psychotic episode is classically viewed as a critical period which management is important in determining the long-term outcome of the schizophrenia (SCZ). For this reason, the duration of untreated illness (DUI), defined as the interval between the onset of the psychiatric disorder and the administration of the first pharmacological treatment, is a clinical variable that has been increasingly investigated due to its potentially modifiable nature and its value as a predictor of outcome. DUI is poorly applicable and highly unreliable in psychosis. The present critical review examines the impact of DUI and its more operative definition of "duration of untreated psychosis" (DUP) in the course and outcome of SCZ, focusing on its epidemiologic, clinical, prognostic factors. Length of DUP has been identified as positively related to a worst treatment response, symptom control and overall functional outcome in SCZ. Negative symptoms appear to be prominently related to longer DUP. Neuroimaging correlates of DUP have not been clearly outlined: few of the studies considering first episode patients and DUP showed structural abnormalities. A low proportion of significant associations were found mostly in cerebellum and occipital lobe of patients with longer DUP. Also, evidence of an inverse correlation between cognitive alterations and DUP is not conclusive. DUI and DUP are multidimensional constructs that imply both intrinsic, illness related (e.g. subtle symptoms at onset) and extrinsic factors (e.g. access to mental health services), so that from its study sprouted in the last decades First-Episode Units, aimed at providing secondary prevention in SCZ such as providing a timely diagnosis and treatment to patients experiencing their first psychotic episode. Early intervention seems to ensure a shortened DUP, especially for people presenting with brief limited intermittent psychotic symptoms, and, ultimately, ensure a more favorable prognosis for patients affected by SCZ. PMID- 27717831 TI - Religious and spiritual importance moderate relation between default mode network connectivity and familial risk for depression. AB - Individuals at high risk for depression have increased default mode network (DMN) connectivity, as well as reduced inverse connectivity between the DMN and the central executive network (CEN) [8]. Other studies have indicated that the belief in the importance of religion/spirituality (R/S) is protective against depression in high risk individuals [5]. Given these findings, we hypothesized that R/S importance would moderate DMN connectivity, potentially reducing DMN connectivity or increasing DMN-CEN inverse connectivity in individuals at high risk for depression. Using resting-state functional connectivity MRI (rs-fcMRI) in a sample of 104 individuals (aged 11-60) at high and low risk for familial depression, we previously reported increased DMN connectivity and reduced DMN-CEN inverse connectivity in high risk individuals. Here, we found that this effect was moderated by self-report measures of R/S importance. Greater R/S importance in the high risk group was associated with decreased DMN connectivity. These results may represent a protective neural adaptation in the DMN of individuals at high risk for depression, and may have implications for other meditation-based therapies for depression. PMID- 27717832 TI - Hormonal modulation of novelty processing in women: Enhanced under working memory load with high dehydroepiandrosterone-sulfate-to-dehydroepiandrosterone ratios. AB - Several studies have suggested that dehydroepiandrosterone (DHEA) and dehydroepiandrosterone-sulfate (DHEAS) may enhance working memory and attention, yet current evidence is still inconclusive. The balance between both forms of the hormone might be crucial regarding the effects that DHEA and DHEAS exert on the central nervous system. To test the hypothesis that higher DHEAS-to-DHEA ratios might enhance working memory and/or involuntary attention, we studied the DHEAS to-DHEA ratio in relation to involuntary attention and working memory processing by recording the electroencephalogram of 22 young women while performing a working memory load task and a task without working memory load in an audio visual oddball paradigm. DHEA and DHEAS were measured in saliva before each task. We found that a higher DHEAS-to-DHEA ratio was related to enhanced auditory novelty-P3 amplitudes during performance of the working memory task, indicating an increased processing of the distracter, while on the other hand there was no difference in the processing of the visual target. These results suggest that the balance between DHEAS and DHEA levels modulates involuntary attention during the performance of a task with cognitive load without interfering with the processing of the task-relevant visual stimulus. PMID- 27717833 TI - Genetic analysis of the CHCHD2 gene in Chinese patients with familial essential tremor. AB - Recently, Funayama et al. identified CHCHD2 as a novel causative gene of Parkinson disease (PD). However, the relationship between CHCHD2 and essential tremor (ET) patients was still unknown. Genetic analysis of CHCHD2 gene was conducted in 60 probands of ET families with autosomal dominant inheritance and 90 healthy controls in Chinese population. No pathogenic CHCHD2 mutation was found in ET patients. However, we identified one rare variant, c.5C>T, a reported risk variant for sporadic PD in Japanese populations, and examined the frequency of three common variants. Our results suggested that CHCHD2 mutations may be rare in Chinese familial ET patients. PMID- 27717835 TI - A resting-state fMRI study on early-stage drug-naive Parkinson's disease patients with drooling. AB - OBJECTIVE: Drooling is a common symptom in Parkinson's disease (PD). This study used resting-state functional MRI (fMRI) to evaluate the brain connectivity of cortico-striatal circuits in PD patients with drooling. METHOD: We enrolled 30 early-stage drug-naive PD patients and 30 matched normal controls. Among the PD patients, 15 patients were classified as "droolers" with the presence of drooling and 15 patients as "non-droolers" with the absence of drooling. All participants underwent resting-state fMRI scans on a 3-T MR system, focusing on the functional connectivity of striatum subregions. RESULTS: Compared with PD patients without drooling, PD patients with drooling showed the significantly reduced functional connectivity of putamen within bilateral sensorimotor cortices, superior and inferior parietal lobules and areas in the right occipital and temporal lobes. No increased functional connectivity was found between the two PD subgroups. In addition, compared with healthy controls, both PD subgroups showed the functional connectivity alterations in cortico-striatal loops. The decreased functional connectivity was prominent in the most affected posterior putamen, and the increased functional connectivity was evident only in the relatively unaffected anterior striatum and caudate. CONCLUSION: By studying a cohort of early-stage drug-naive PD patients, we eliminated the potential confounding effects of antiparkinson medication on the functional integration of neural networks. We demonstrated decreased connectivity within cortico-striatal networks in PD patients with drooling. These findings might be helpful for promoting the further understanding of neural system effects underlying drooling in PD. Our result is preliminary and further investigation is needed. PMID- 27717834 TI - Does medial temporal lobe thickness mediate the association between risk factor burden and memory performance in middle-aged or older adults with metabolic syndrome? AB - Metabolic syndrome (MetS) is a cluster of cardiovascular and metabolic abnormalities that together may increase the risk of developing cognitive decline and dementia; however, the neural substrate is incompletely understood. We investigated cortical thickness in the medial temporal lobe (MTL), hippocampal volume, as well as relationships among metabolic risk factor burden, structure and memory performance. Path-analytic models were tested to explore the relations between MetS risk factor, structure and memory performance. Participants were 65 non-demented, middle-aged and older adults, 34 with and 31 without metabolic syndrome. We analyzed archival T1-weighted magnetic resonance imaging (MRI) acquired at 3T and Total Recall and Delayed Recall scores from the Brief Visuospatial Memory Test Revised (BVMT-R). Middle-aged adults with MetS showed less MTL thickness, particularly in entorhinal cortex; while older adults showed a trend for left hippocampal volume loss. Lower MTL thickness, particularly in entorhinal cortex, was associated with greater metabolic risk factor burden in middle-aged adults. In older adults, hippocampal volume was associated with Total Recall and Delayed Recall, while in middle-age entorhinal cortical thickness mediated the association between metabolic disease burden and episodic memory function. The differential findings in middle-aged and older adults with MetS contribute to an understanding of the relationships between metabolic syndrome, structural changes in the brain and increased risk for cognitive decline. PMID- 27717836 TI - Managing hypertriglyceridemia in children with systemic lupus erythematosus: Two sides of the same coin. AB - Hypertriglyceridemia is common in children with systemic lupus erythematosus (SLE). A retrospective analysis of the baseline clinical-pathological presentation and treatment outcome (status of lipid profiles) was performed in two children with SLE, who presented with extreme hypertriglyceridemia over a follow-up period of four weeks. The children were treated with prednisolone, mycophenolate mofetil (MMF), hydroxychloroquine and hypolipidemic agents, depending on their disease status. On serial follow-up, the first child showed a significantly raised serum triglyceride level after receiving one week of oral prednisolone therapy. Anti-lipoprotein-lipase (LPL) autoantibody was absent. Lipid profile levels of this child gradually improved after replacing oral prednisolone with another immunosuppressant, namely MMF. The second child presented with extreme hypertriglyceridemia with positive anti-LPL autoantibody. She responded to plasmapheresis followed by increasing the dose of immunosuppressant. So, extreme hypertriglyceridemia in children with SLE may be steroid induced or due to presence of anti-LPL auto antibody. Management should be individualized depending on the etiology. PMID- 27717838 TI - Replantation or revascularization for the treatment of hand degloving injuries. AB - PURPOSE: The purpose of this study was to explore effective strategies of replantation or revascularization for the treatment of hand degloving injuries. METHODS: Ten patients who had received replantation or revascularization surgery for hand degloving injury between 2002 and 2014 were included for this study. The average age at the time of surgery was 34.5 years (range 18-49 years). There were nine left and one right hand replantations. The cause of injury was an industrial machine press in all of them. The skin was avulsed from the palm to the distal phalangeal level in five patients, to the middle phalangeal level in four patients, and avulsed from the wrist crease level completely in one patient. All the degloved flaps were revascularized. RESULTS: Both the degloved flap and phalanges survived completely in one patient, and partial survival of the flap occurred in the remaining patients. The patients were followed up from 15 months to 78 months (average, 38.1 months). Sensory recovery of the finger pulp ranged from S2 to S3+. Michigan Hand outcome Questionnaire (MHQ) score ranged from 29 to 96 with an average of 69.5. CONCLUSIONS: Midlateral incision to reduce the secondary damage to the capillaries, repair of more vessels for circulation, application of full-thickness skin grafts to enlarge the survival area, and use of anticoagulation protocols during and postsurgery may be beneficial to improve the replantation survival of the degloved skin. PMID- 27717839 TI - Is the snail shell repair process really influenced by eggshell membrane as a template of foreign scaffold? AB - Biominerals are inorganic-organic hybrid composites formed via self-assembled bottom up processes under mild conditions. Biominerals show interesting physical properties, controlled hierarchical structures and robust remodeling or repair mechanisms. Biological processes associated with biominerals remain to be developed into practical engineering processes. Therefore, the formation of biominerals is inspiring for the design of materials, especially those fabricated at ambient temperatures. The study described herein involves the influence of chicken outer eggshell membrane on the type of calcium carbonate (CaCO3) polymorph deposited on the shell of the land snail Helix aspersa during the repair process after an injury. A piece of snail shell was removed by perforating a hole from the largest body whorl. The operated area was left either uncovered or covered with either a thermoplastic flexible polyolefin-based film Parafilm(r) or a piece of chicken eggshell membrane. The repaired shells of control and experimental animals were analyzed using SEM, EDS, Raman and FTIR spectroscopies. We found that in the presence of eggshell membrane, the polymorph deposited on the substratum during the first hours resembles calcite, the polymorph present in eggshell normal formation, but at 24 and 48h, when snail mantle cells produced their normal organic matrix (mainly beta-chitin plus proteins and proteoglycans), the polymorph deposited is aragonite, the characteristic polymorph of Helix shell. Therefore, the eggshell membrane influences the type of polymorph, but only in the initial stages of biomineral deposition, before an organic matrix layer is deposited by the snail. PMID- 27717840 TI - Analysis of nasal potential in murine cystic fibrosis models. AB - The nasal epithelium of the mouse closely mimics the bioelectrical phenotype of the human airways. Ion transport across the nasal epithelium induces a nasal transepithelial potential difference. Its measurement by a relatively non invasive method adapted from humans allows in vivo longitudinal measurements of CFTR-dependent ionic transport in the murine nasal mucosa. This test offers a useful tool to assess CFTR function in preclinical studies for novel therapeutics modulating CFTR activity. Here we extensively review work done to assess transepithelial transport in the murine respiratory epithelium in the basal state and after administration of CFTR modulators. Factors of variability and discriminative threshold between the CF and the WT mice for different readouts are discussed. PMID- 27717837 TI - An integrative view of cisplatin-induced renal and cardiac toxicities: Molecular mechanisms, current treatment challenges and potential protective measures. AB - Cisplatin is currently one of the most widely-used chemotherapeutic agents against various malignancies. Its clinical application is limited, however, by inherent renal and cardiac toxicities and other side effects, of which the underlying mechanisms are only partly understood. Experimental studies show cisplatin generates reactive oxygen species, which impair the cell's antioxidant defense system, causing oxidative stress and potentiating injury, thereby culminating in kidney and heart failure. Understanding the molecular mechanisms of cisplatin-induced renal and cardiac toxicities may allow clinicians to prevent or treat this problem better and may also provide a model for investigating drug induced organ toxicity in general. This review discusses some of the major molecular mechanisms of cisplatin-induced renal and cardiac toxicities including disruption of ionic homeostasis and energy status of the cell leading to cell injury and cell death. We highlight clinical manifestations of both toxicities as well as (novel)biomarkers such as kidney injury molecule-1 (KIM-1), tissue inhibitor of metalloproteinase-1 (TIMP-1) and N-terminal pro-B-type natriuretic peptide (NT-proBNP). We also present some current treatment challenges and propose potential protective strategies including combination therapy with novel pharmacological compounds that might mitigate or prevent these toxicities, which include the use of hydrogen sulfide. PMID- 27717841 TI - A high-throughput screen for mitochondrial function reveals known and novel mitochondrial toxicants in a library of environmental agents. AB - Mitochondrial toxicity is emerging as a major mechanism underlying serious human health consequences. This work performs a high-throughput screen (HTS) of 176 environmental chemicals for mitochondrial toxicity utilizing a previously reported biosensor platform. This established HTS confirmed known mitochondrial toxins and identified novel mitotochondrial uncouplers such as 2, 2' Methylenebis(4-chlorophenol) and pentachlorophenol. It also identified a mitochondrial 'structure activity relationship' (SAR) in the sense that multiple environmental chlorophenols are mitochondrial inhibitors and uncouplers. This study demonstrates proof-of-concept that a mitochondrial HTS assay detects known and novel environmental mitotoxicants, and could be used to quickly evaluate human health risks from mitotoxicants in the environment. PMID- 27717842 TI - Education, Employment, Income, and Marital Status Among Adults Diagnosed With Inflammatory Bowel Diseases During Childhood or Adolescence. AB - BACKGROUND & AIMS: We aimed to assess levels of education attained, employment, and marital status of adults diagnosed with inflammatory bowel diseases (IBD) during childhood or adolescence, compared with healthy individuals in Canada. METHODS: We performed a cross-sectional study of adults diagnosed with IBD in childhood or adolescence at Children's Hospital in Winnipeg, Manitoba from January 1978 through December 2007. Participants (n = 112) answered a semi structured questionnaire on educational achievements, employment, and marital status. Patients were matched for age and sex with random healthy individuals from the 2012 Canadian Community Health Survey (controls, 5 per patient). Conditional binary logistic regression and random-effects ordinal logistic regression models were used for analysis. RESULTS: Patients were followed for a mean duration of 14.3 years (range, 3.1-34.5 years). Persons with IBD were more likely to earn more money per annum and attain a post-secondary school degree or receive a diploma than controls (odds ratio, 1.72; 95% confidence interval, 1.13 2.60; P < .01 and odds ratio, 2.73; 95% confidence interval, 1.48-5.04; P < .01, respectively). There was no significant difference between patients and controls in employment or marital status. CONCLUSIONS: Adults diagnosed with IBD during childhood seem to achieve higher education levels than individuals without IBD. This observation should provide reassurance to children with IBD and their parents. ClinicalTrials.gov number: NCT02152241. PMID- 27717843 TI - Homology modeling of Homo sapiens lipoic acid synthase: Substrate docking and insights on its binding mode. AB - Lipoic acid synthase (LIAS) is an iron-sulfur cluster mitochondrial enzyme which catalyzes the final step in the de novo pathway for the biosynthesis of lipoic acid, a potent antioxidant. Recently there has been significant interest in its role in metabolic diseases and its deficiency in LIAS expression has been linked to conditions such as diabetes, atherosclerosis and neonatal-onset epilepsy, suggesting a strong inverse correlation between LIAS reduction and disease status. In this study we use a bioinformatics approach to predict its structure, which would be helpful to understanding its role. A homology model for LIAS protein was generated using X-ray crystallographic structure of Thermosynechococcus elongatus BP-1 (PDB ID: 4U0P). The predicted structure has 93% of the residues in the most favour region of Ramachandran plot. The active site of LIAS protein was mapped and docked with S-Adenosyl Methionine (SAM) using GOLD software. The LIAS-SAM complex was further refined using molecular dynamics simulation within the subsite 1 and subsite 3 of the active site. To the best of our knowledge, this is the first study to report a reliable homology model of LIAS protein. This study will facilitate a better understanding mode of action of the enzyme-substrate complex for future studies in designing drugs that can target LIAS protein. PMID- 27717844 TI - Equilibria of oligomeric proteins under high pressure - A theoretical description. AB - High pressure methods have become a useful tool for studying protein structure and stability. Using them, various physico-chemical processes including protein unfolding, aggregation, oligomer dissociation or enzyme-activity decrease were studied on many different proteins. Oligomeric protein dissociation is a process that can perfectly utilize the potential of high-pressure techniques, as the high pressure shifts the equilibria to higher concentrations making them better observable by spectroscopic methods. This can be especially useful when the oligomeric form is highly stable at atmospheric pressure. These applications may be, however, hindered by less intensive experimental response as well as interference of the oligomerization equilibria with unfolding or aggregation of the subunits, but also by more complex theoretical description. In this study we develop mathematical models describing different kinds of oligomerization equilibria, both closed (equilibrium of monomer and the highest possible oligomer without any intermediates) and consecutive. Closed homooligomer equilibria are discussed for any oligomerization degree, while the more complex heterooligomer equilibria and the consecutive equilibria in both homo- and heterooligomers are taken into account only for dimers and trimers. In all the cases, fractions of all the relevant forms are evaluated as functions of pressure and concentration. Significant points (inflection points and extremes) of the resulting transition curves, that can be determined experimentally, are evaluated as functions of pressure and/or concentration. These functions can be further used in order to evaluate the thermodynamic parameters of the system, i.e. atmospheric-pressure equilibrium constants and volume changes of the individual steps of the oligomer dissociation processes. PMID- 27717846 TI - microRNA-539 suppresses tumor growth and tumorigenesis and overcomes arsenic trioxide resistance in hepatocellular carcinoma. AB - AIMS: Dysregulation of microRNAs (miRNAs) plays a critical role in tumor growth and progression. In this study, we sought to explore the expression and biological roles of miR-539 in hepatocellular carcinoma (HCC). MAIN METHODS: The expression of miR-539 in human HCC tissues and cell lines was examined. The effects of miR-539 overexpression on cell growth, tumorigenicity, arsenic trioxide resistance of HCC cells were determined. The signaling pathways involved in the action of miR-539 in HCC were also investigated. KEY FINDINGS: miR-539 was downregulated in HCC tissues and cells, relative to corresponding controls. Overexpression of miR-539 inhibited HCC cell viability and colony formation in vitro and impaired tumorigenesis of HCC cells in vivo. Transfection with miR-539 mimic significantly induced apoptosis in HepG2 cells, which was coupled with reduced expression of anti-apoptotic proteins Bcl-2 and Bcl-xL and decreased phosphorylation of Stat3. Overexpression of a constitutively active form of Stat3 partially blocked miR-539-mediated apoptosis. Enforced expression of miR-539 resensitized arsenic trioxide-resistant HCC cells to arsenic trioxide. Intratumoral delivery of miR-539 mimic significantly retarded the growth of xenograft tumors from arsenic trioxide-resistant HCC cells by about 35%, compared to delivery of control miRNA (P<0.05). In combination with arsenic trioxide, miR 539 mimic yielded about 80% decrease in tumor burden. SIGNIFICANCE: miR-539 functions as a tumor suppressor in HCC and reexpression of this miRNA offers a potential therapeutic strategy for this disease. PMID- 27717845 TI - Janus kinase 2 activation participates in prostaglandin E2-induced hyperalgesia. AB - Prostaglandin E2 (PGE2) is one of the major signaling molecules involved in hyperalgesia, acting directly on nociceptors and resulting in the activation of PKA and PKC. Once active, these kinases phosphorylate many cellular proteins, resulting in changes on nociceptors sensorial transduction properties. The Janus Kinases (JAKs) are a family of intracellular signaling molecules generally associated with cytokine signaling, and their activity can be increased in nociceptors after peripheral inflammation. However, there are no evidences of JAKs direct involvement in PGE2 mediated sensitization of nociceptors. Therefore, the aim of the present study was to explore a possible role for JAKs in PGE2 mediated sensitization. In cultured dorsal root ganglion (DRG) neurons, we observed that the administration of PGE2 increases capsaicin induced calcium transients, and a pre-incubation of DRG cells with the JAK inhibitor AG490 blocks this PGE2 in vitro effect. Intrathecal administration of AG490 to ten-weeks-old male Wistar rats reduces the hyperalgesia induced by the intraplantar administration of PGE2 or carrageenan in the right hind paw. We also observed that carrageenan administration in the right hind paw induced an increase in membrane associated PKCepsilon in the ipsilateral L5 DRG, and this increase was blocked by intrathecal AG490 administration. In conclusion the present study indicates that the JAKs expressed in the DRG and spinal cord may have a role in the sensitization of nociceptors by a peripheral inflammatory event. Moreover, the inhibition of JAKs may be a possible novel pharmacological target for the control of the inflammatory hyperalgesia. PMID- 27717847 TI - An updated meta-analysis of transforming growth factor-beta1 gene: Three well characterized polymorphisms with asthma. AB - The association between TGF-beta1 polymorphisms and asthma risk has been widely reported, but results were controversial. We performed this meta-analysis based on the Preferred Reporting Items for Systematic Reviews and meta-analyses statement (PRISMA). Electronic database of Pub Med, Web of Science, CBM, and CNKI were searched for eligible articles published up to September, 2013. The effect summary odds ratio (OR) and 95% confidence intervals were obtained. Finally, a total of 20 articles were identified, 17 studies with 3694 cases and 5613 controls for C-509T polymorphism, 7 studies with 1109 cases and 1098 controls for T869C polymorphism and 5 studies with 849 cases and 829 controls for G915C polymorphism. For C-509T, significant associations with asthma were found in Asians (TT+TC vs. CC: P=0.004, OR=1.43, 95%CI=1.12-1.81, Pheterogeneity=0.001) and in Caucasians (P=0.05, OR=1.16, 95%CI=1.00-1.34, Pheterogeneity=0.36). With respect to T869C, a small significant association was observed in overall analysis of allele contrasts(C vs. T: OR=1.14, 95%CI: 1.01-1.29, P=0.03) and homozygote comparison (CC vs. TT: OR=1.29, 95%CI: 1.00-1.65, P=0.05), but no significant risks were found among Caucasian population and Asian population. For G915C polymorphism, no significant association with asthma risk was demonstrated in overall analysis and subgroup analyses according to ethnicity for all genetic models. This meta-analysis suggested that TGF-beta1 C-509T and T869C polymorphisms may be risk factors for asthma. PMID- 27717849 TI - Am I or am I not proarrhythmic? Comparison of various classifications of drug TdP propensity. AB - This review aims to present and compare various Torsade de pointes propensity classification schemes of drugs that are publicly available from many scientific sources. We have also tracked and listed the compounds that were differently categorized. Additionally, we would like to draw attention to the need for establishing a general, standardized classification of a drug's proarrhythmic propensity. This is especially important in the current drug development process because of the changing paradigm of drug cardiac safety assessment. PMID- 27717848 TI - Colon cancer-derived myofibroblasts increase endothelial cell migration by glucocorticoid-sensitive secretion of a pro-migratory factor. AB - Angiogenesis is important in cancer progression and can be influenced by tumor associated myofibroblasts. We addressed the hypothesis that glucocorticoids indirectly affect angiogenesis by altering the release of pro-angiogenic factors from colon cancer-derived myofibroblasts. Our study shows that glucocorticoids reduced prostanoids, urokinase-type plasminogen activator (uPA) and angiopoietin like protein-2 (ANGPTL2) levels, but increased angiogenin (ANG) in supernatant from human CT5.3hTERT colon cancer-derived myofibroblasts. Conditioned medium from solvent- (CMS) and dexamethasone (Dex)-treated (CMD) myofibroblasts increased human umbilical vein endothelial cell (HUVEC) proliferation, but did not affect expression of pro-angiogenic factors or tube-like structure formation (by HUVECs or human aortic ECs). In a HUVEC scratch assay CMS-induced acceleration of wound healing was blunted by CMD treatment. Moreover, CMS-induced neovessel growth in mouse aortic rings ex vivo was also blunted using CMD. The latter effect could be ascribed to both Dex-driven reduction of secreted factors and potential residual Dex present in CMD (indicated using a dexamethasone-spiked CMS control). A similar control in the scratch assay, however, revealed that altered levels of factors in the CMD, and not potential residual Dex, were responsible for decreased wound closure. In conclusion, our results suggest that glucocorticoids indirectly alter endothelial cell function during tumor development in vivo. PMID- 27717851 TI - Tuberculosis drug discovery needs public-private consortia. PMID- 27717852 TI - Personality and problem-solving in common mynas (Acridotheres tristis). AB - Animals show consistent individual differences in behaviour across time and/or contexts. Recently, it has been suggested that proactive personality types might also exhibit fast cognitive styles. The speed with which individuals sample environmental cues is one way in which correlations between personality and cognition might arise. Here, we measured a collection of behavioural traits (competitiveness, neophobia, neophilia, task-directed motivation and exploration) in common mynas (Acridotheres tristis) and measured their relationship with problem solving. We predicted that fast solving mynas would interact with (i.e. sample) the problem solving task at higher rates, but also be more competitive, less neophobic, more neophilic, and more exploratory. Mynas that were faster to solve a novel foraging problem were no more competitive around food and no more inclined to take risks. Unexpectedly, these fast-solving mynas had higher rates of interactions with the task, but also displayed lower levels of exploration. It is possible that a negative relation between problem solving and spatial exploration arose as a consequence of how inter-individual variation in exploration was quantified. We discuss the need for greater consensus on how to measure exploratory behaviour before we can advance our understanding of relationships between cognition and personality more effectively. PMID- 27717850 TI - Learning from the past for TB drug discovery in the future. AB - Tuberculosis drug discovery has shifted in recent years from a primarily target based approach to one that uses phenotypic high-throughput screens. As examples of this, through our EU-funded FP7 collaborations, New Medicines for Tuberculosis was target-based and our more-recent More Medicines for Tuberculosis project predominantly used phenotypic screening. From these projects we have examples of success (DprE1) and failure (PimA) going from drug to target and from target to drug, respectively. It is clear that we still have much to learn about the drug targets and the complex effects of the drugs on Mycobacterium tuberculosis. We propose a more integrated approach that learns from earlier drug discovery efforts that could help to move drug discovery forward. PMID- 27717853 TI - Determination of collagen type IV by Surface Plasmon Resonance Imaging using a specific biosensor. AB - Serum collagen type IV (COLIV) is a promising tumor marker. High COLIV concentrations have been found in the serum of patients with colorectal, gastric, lung, liver and breast cancers. The aim of this work was to develop a biosensor for use with the Surface Plasmon Resonance Imaging (SPRI) technique for COLIV determination. The biosensor consists of glass covered with gold and immobilized monoclonal mouse anti-human collagen type IV antibody via cysteamine linker. The biosensor works selectively within a dynamic response range between 10 and 300 ng mL-1, with LOD 2.4 ng mL-1 and LOQ 8 ng mL-1. The precision of determination is 4.7% at a 150 ng mL-1 COLIV spike and 8.0% at a 20 ng mL-1 spike, with recoveries of 101% and 106% respectively. A 100-fold excess of collagen I, albumin, laminin and fibronectin is tolerated. The average COLIV blood plasma concentration of healthy donors determined by the developed method was 69 +/- 10 ng mL-1, while the median of six results available in the literature was approximately 80 ng mL 1. The average COLIV blood plasma concentration of breast cancer patients was 360 +/- 68 ng mL-1, showing the high potential of COLIV as a marker of this type of cancer. PMID- 27717854 TI - Optimization of the formation of embedded multicellular spheroids of MCF-7 cells: How to reliably produce a biomimetic 3D model. AB - To obtain a multicellular MCF-7 spheroid model to mimic the three-dimensional (3D) of tumors, the microwell liquid overlay (A) and hanging-drop/agar (B) methods were first compared for their technical parameters. Then a method for embedding spheroids within collagen was optimized. For method A, centrifugation assisted cells form irregular aggregates but not spheroids. For method B, an extended sedimentation period of over 24 h for cell suspensions and increased viscosity of the culture medium using methylcellulose were necessary to harvest a dense and regular cell spheroid. When the number was less than 5000 cells/drop, embedded spheroids showed no tight cores and higher viability than the unembedded. However, above 5000 cells/drop, cellular viability of embedded spheroids was not significantly different from unembedded spheroids and cells invading through the collagen were in a sun-burst pattern with tight cores. Propidium Iodide staining indicated that spheroids had necrotic cores. The doxorubicin cytotoxicity demonstrated that spheroids were less susceptible to DOX than their monolayer cells. A reliable and reproducible method for embedding spheroids using the hanging-drop/agarose method within collagen is described herein. The cell culture model can be used to guide experimental manipulation of 3D cell cultures and to evaluate anticancer drug efficacy. PMID- 27717855 TI - Isothermal titration calorimetry for drug design: Precision of the enthalpy and binding constant measurements and comparison of the instruments. AB - Isothermal titration calorimetry (ITC) is one of the most robust label- and immobilization-free techniques used to measure protein - small molecule interactions in drug design for the simultaneous determination of the binding affinity (DeltaG) and the enthalpy (DeltaH), both of which are important parameters for structure-thermodynamics correlations. It is important to evaluate the precision of the method and of various ITC instrument models by performing a single well-characterized reaction. The binding between carbonic anhydrase II and acetazolamide was measured by four ITC instruments - PEAQ-ITC, iTC200, VP-ITC, and MCS-ITC and the standard deviation of DeltaG and DeltaH was determined. Furthermore, the limit of an approach to reduce the protein concentration was studied for a high-affinity reaction (Kd = 0.3 nM), too tight to be measured by direct (non-displacement) ITC. Chemical validation of the enthalpy measurements is discussed. PMID- 27717857 TI - Localized surface plasmon resonance based gold nanobiosensor: Determination of thyroid stimulating hormone. AB - An immunoassay method based on the peak shift of the localized surface plasmon resonance (LSPR) absorption maxima has been developed for the determination of the thyroid stimulating hormone (TSH) in human blood serum. The anti-TSH antibody was adsorbed on the synthesized gold nanoparticles by electrostatic forces. The efficiency of the nanobiosensor was improved by optimizing the factors affecting the probe construction such as the pH and the antibody to gold nanoparticles ratio. Dynamic light scattering was applied for the characterization of the constructed probe. The amount of peak shift of the LSPR absorption maxima was selected as the basis for determination of TSH antigen. The linear dynamic range of 0.4-12.5 mIU L-1 and the calibration sensitivity of 1.71 L mIU-1 were obtained. The human control serum sample was analyzed for TSH by constructed nanobiosensor and the acceptable results were obtained. PMID- 27717856 TI - Triglyceride depletion of brown adipose tissue enables analysis of mitochondrial respiratory function in permeabilized biopsies. AB - The research on mitochondrial functions in adipocytes has increasingly evidenced that mitochondria plays an important role in the onset and/or progression of obesity and related pathologies. Mitochondrial function in brown adipose tissue (BAT) has been classically assessed by measuring either the levels/activity of mitochondrial enzymes, or the respiration in isolated mitochondria. Isolation of mitochondria is not advantageous because it demands significant time and amount of tissue and, as tissue homogenates, disrupts biochemical and physical connections of mitochondria within the cell. Here, we described a new and efficient protocol to analyze the mitochondrial respiratory states in BAT biopsies that relies on intracellular triglyceride depletion followed by tissue permeabilization. In addition to minimizing tissue requirements to ~17 mg wet weight, the proposed protocol enabled analysis of all mitochondrial respiratory states, including phosphorylation (OXPHOS), no-phosphorylation (LEAK), and uncoupled (ETS) states, as well as the use of substrates for complex I, complex II, and cytochrome c; together, these features demonstrated mitochondrial integrity and validated the preparation efficacy. Therefore, the protocol described here increases the possibilities of answering physiological questions related to small BAT regions of human and animal models, which shall help to unravel the mechanisms that regulate mitochondrial function in health and disease. PMID- 27717858 TI - Poverty and prevalence of antimicrobial resistance in invasive isolates. AB - OBJECTIVES: To evaluate the association between the income status of a country and the prevalence of antimicrobial resistance (AMR) in the three most common bacteria causing infections in hospitals and in the community: third-generation cephalosporin (3GC)-resistant Escherichia coli, methicillin-resistant Staphylococcus aureus (MRSA), and 3GC-resistant Klebsiella species. METHODS: Using 2013-2014 country-specific data from the ResistanceMap repository and the World Bank, the association between the prevalence of AMR in invasive samples and the gross national income (GNI) per capita was investigated through linear regression with robust standard errors. To account for non-linear association with the dependent variable, GNI per capita was log-transformed. RESULTS: The models predicted an 11.3% (95% confidence interval (CI) 6.5-16.2%), 18.2% (95% CI 11-25.5%), and 12.3% (95% CI 5.5-19.1%) decrease in the prevalence of 3GC resistant E. coli, 3GC-resistant Klebsiella species, and MRSA, respectively, for each log GNI per capita. The association was stronger for 3GC-resistant E. coli and Klebsiella species than for MRSA. CONCLUSIONS: A significant negative association between GNI per capita and the prevalence of MRSA and 3GC-resistant E. coli and Klebsiella species was found. These results underscore the urgent need for new policies aimed at reducing AMR in resource-poor settings. PMID- 27717859 TI - Risk factors for human helminthiases in rural Philippines. AB - BACKGROUND: A cross-sectional survey was performed in 2012 among 18 rural barangays in Northern Samar, the Philippines in order to determine the prevalence of single and multiple species helminth infections and the underlying risk factors of acquiring one or more parasites. METHODS: A total of 6976 participants who completed a medical questionnaire and provided a stool sample for examination were included in the final analysis. RESULTS: The overall prevalence rates of Schistosoma japonicum, Ascaris lumbricoides, Trichuris trichiura, and hookworm were found to be moderate to high at 28.9%, 36.5%, 61.8%, and 28.4%, respectively. However, the prevalence of harbouring any of the helminths was found to be higher at 75.6%. Significant variation was evident among the predicted barangay-specific random effects for infection with S. japonicum (barangay variance of 0.66, 95% confidence interval 0.31-1.40) and for any helminth infection (barangay variance of 0.63, 95% confidence interval 0.30 1.29). The predictive models showed, with greater than 80% sensitivity and specificity, that low socio-economic status, low levels of education, poor sanitation, proximity to water sources, occupation (i.e., farming and fishing), and male sex were all reliable indicators of infection status. CONCLUSIONS: This study will aid in the targeting of limited resources for national treatment and WASH (water, sanitation, and hygiene) efforts in low- and middle-income countries. PMID- 27717860 TI - The Effects of Melatonin on Ethylene Glycol-induced Nephrolithiasis: Role on Osteopontin mRNA Gene Expression. AB - OBJECTIVE: To evaluate the protective effects of melatonin (Mel) on an ethylene glycol (EG)-induced nephrolithiasis model in rats. MATERIALS AND METHODS: Thirty two Wistar albino rats were divided into 4 groups: control, EG, prevention Mel (Mel + EG + Mel), and therapeutic Mel (EG + Mel). EG (0.75%) was added to drinking water to create nephrolithiasis model. The EG group received EG and the Mel + EG + Mel group received both EG and Mel for 8 weeks. In the EG + Mel group, EG is given for 8 weeks and Mel is given for the last 4 weeks of the experiment. At the end of experimental period, urine, blood samples, and tissues were collected. RESULTS: In 24-hour urine samples, calcium, citrate, and creatinine levels were decreased and oxalate levels were increased in the EG group, whereas Mel prevention and Mel treatment reversed these parameters back to control levels. Malondialdehyde, glutathione activities, myeloperoxidase, superoxide dismutase levels, and caspase-3 activity showed improvements in the Mel-treated groups when compared with the EG group. 8-Hydroxydeoxyguanosine, matrix metalloproteinase 9 levels, N-acetyl-beta-glucosaminidase activity, and osteopontin mRNA expression were elevated in the EG group and decreased back to control levels in the Mel + EG + Mel and EG + Mel groups. Histological examination showed improvement in the Mel-treated groups when compared with the EG group. CONCLUSION: Mel can prevent crystalluria and kidney damage due to crystal formation and aggregation. It can be considered as a potential prophylactic and protective agent in high-risk patients with urinary stone formation or recurrence if supported by further clinical studies.

PMID- 27717864 TI - Extensive testing or focused testing of patients with elevated liver enzymes. AB - BACKGROUND & AIMS: Many patients have elevated serum aminotransferases reflecting many underlying conditions, both common and rare. Clinicians generally apply one of two evaluative strategies: testing for all diseases at once (extensive) or just common diseases first (focused). METHODS: We simulated the evaluation of 10,000 adult outpatients with elevated with alanine aminotransferase to compare both testing strategies. Model inputs employed population-based data from the US (National Health and Nutrition Examination Survey) and Britain (Birmingham and Lambeth Liver Evaluation Testing Strategies). Patients were followed until a diagnosis was provided or a diagnostic liver biopsy was considered. The primary outcome was US dollars per diagnosis. Secondary outcomes included doctor visits per diagnosis, false-positives per diagnosis and confirmatory liver biopsies ordered. RESULTS: The extensive testing strategy required the lowest monetary cost, yielding diagnoses for 54% of patients at $448/patient compared to 53% for $502 under the focused strategy. The extensive strategy also required fewer doctor visits (1.35 vs. 1.61 visits/patient). However, the focused strategy generated fewer false-positives (0.1 vs. 0.19/patient) and more biopsies (0.04 vs. 0.08/patient). Focused testing becomes the most cost-effective strategy when accounting for pre-test probabilities and prior evaluations performed. This includes when the respective prevalence of alcoholic, non-alcoholic and drug induced liver disease exceeds 51.1%, 53.0% and 13.0%. Focused testing is also the most cost-effective strategy in the referral setting where assessments for viral hepatitis, alcoholic and non-alcoholic fatty liver disease have already been performed. CONCLUSIONS: Testing for elevated liver enzymes should be deliberate and focused to account for pre-test probabilities if possible. LAY SUMMARY: Many patients have elevated liver enzymes reflecting one of many possible liver diseases, some of which are very common and some of which are rare. Tests are widely available for most causes but it is unclear whether clinicians should order them all at once or direct testing based on how likely a given disease may be given the patient's history and physical exam. The tradeoffs of both approaches involve the money spent on testing, number of office visits needed, and false positive results generated. This study shows that if there are no clues available at the time of evaluation, testing all at once saves time and money while causing more false positives. However, if there are strong clues regarding the likelihood of a particular disease, limited testing saves time, money and prevents false positives. PMID- 27717865 TI - Two different analyzing methods for inhibitory reflexes: Do they yield comparable outcomes? AB - BACKGROUND: For the analysis of inhibitory reflexes, no consensus exists regarding the methodology that should be used. The most commonly used methods are the cumulative sum (CUSUM) error box and the t-test. The aim of this study was to assess the interexaminer reliability of those two analyzing methods and to test whether both methods: yield similar results. METHODS: Inhibitory jaw reflexes were recorded from the right masseter muscle of 11 participants (6 males, 5 females). Electrical stimuli were applied at the hairy skin of the upper lip on the right side. In total, 16 stimuli were applied while the participants maintained their clenching level at 10% of their maximum voluntary EMG activity. Two different examiners analyzed the reflex data with two different methods: the CUSUM error box and the t-test. The outcome variables were the number of reflex parts, the reflex area size, and the reflex onset. Comparability between examiners and between the two analyzing methods: was assessed with the use of the intraclass correlation coefficient (ICC). RESULTS: The interexaminer reliability was fair-to-good to excellent for both the CUSUM error box and the t-test analyses and for all the variables tested. The comparability of the two analyzing methods: was fair-to-good. COMPARISON WITH EXISTING METHODS/CONCLUSION: When analyzing the inhibitory reflex data, both the CUSUM error box and the t-test can be used. PMID- 27717866 TI - Neurobasal media facilitates increased specificity of siRNA-mediated knockdown in primary cerebellar cultures. AB - BACKGROUND: Efficient and specific knockdown of proteins in post-mitotic cells such as differentiated neurons can be difficult to achieve. Further, special care must be taken to maintain the health of neurons in vitro. We wanted to achieve knockdown in primary cerebellar granule neurons, which can be effectively grown in NeurobasalTM media. NEW METHOD: We tested the efficiency of siRNA from the Accell range from DharmaconTM when delivered in NeurobasalTM media in contrast to the recommended Accell Delivery media provided by the manufacturer. RESULTS: We observed a more specific knockdown of target in NeurobasalTM media, than in Accell Delivery media when using cerebellar granule neurons. Transfection efficiency and cell viability was comparable between the two media. COMPARISON WITH EXISTING METHODS: Delivery of siRNA in NeurobasalTM media facilitates increased specificity of the knockdown compared to delivery in Accell Delivery media. The off-target effect observed in Accell Delivery media was not a secondary biological response to downregulation of target, but rather a mixture of specific and non-specific off-target effects. CONCLUSIONS: Specific knockdown of target can be achieved in primary cerebellar granule cells using Accell siRNAs in NeurobasalTM media. This method ensures specific knockdown in post-mitotic neurons without the need for biosafety level 2 laboratories, additional reagents, or instruments needed by other transfection. PMID- 27717867 TI - MKK3 influences mitophagy and is involved in cigarette smoke-induced inflammation. AB - Cigarette smoking is the primary risk factor for COPD which is characterized by excessive inflammation and airflow obstruction of the lung. While inflammation is causally related to initiation and progression of COPD, the mitochondrial mechanisms that underlie the associated inflammatory responses are poorly understood. In this context, we have studied the role played by Mitogen activated protein (MAP) kinase kinase 3 (MKK3), a dual-specificity protein kinase, in cigarette smoke induced-inflammation and mitochondrial dysfunction. Serum pro inflammatory cytokines were significantly elevated in WT but not in MKK3-/- mice exposed to Cigarette smoke (CS) for 2 months. To study the cellular mechanisms of inflammation, bone marrow derived macrophages (BMDMs), wild type (WT) and MKK3-/ , were exposed to cigarette smoke extract (CSE) and inflammatory cytokine production and mitochondrial function assessed. The levels of IL-1beta, IL-6, and TNFalpha were increased along with higher reactive oxygen species (ROS) and P NFkappaB after CSE treatment in WT but not in MKK3-/- BMDMs. CSE treatment adversely affected basal mitochondrial respiration, ATP production, maximum respiratory capacity, and spare respiratory capacity in WT BMDMs only. Mitophagy, clearance of dysfunctional mitochondria, was up regulated in CS exposed WT mice lung tissue and CSE exposed WT BMDMs, respectively. The proteomic analysis of BMDMs by iTRAQ (isobaric tags for relative and absolute quantitation) showed up regulation of mitochondrial dysfunction associated proteins in WT and higher OXPHOS (Oxidative phosphorylation) and IL-10 signaling proteins in MKK3-/- BMDMs after CSE exposure, confirming the critical role of mitochondrial homeostasis. Interestingly, we found increased levels of p-MKK3 by immunohistochemistry in COPD patient lung tissues that could be responsible for insufficient mitophagy and disease progression. This study identifies MKK3 as a negative regulator of mitochondrial function and inflammatory responses to CS and suggests that MKK3 could be a therapeutic target. PMID- 27717868 TI - Intermittent hypoxia confers pro-metastatic gene expression selectively through NF-kappaB in inflammatory breast cancer cells. AB - Inflammatory breast cancer (IBC) is the most aggressive form of breast cancer. Treatment options are limited and the mechanisms underlying its aggressiveness are poorly understood. Intermittent hypoxia (IH) causes oxidative stress and is emerging as important regulator of tumor metastasis. Vessels in IBC tumors have been shown to be immature, which is a primary cause of IH. We therefore investigated the relevance of IH for the modulation of gene expression in IBC cells in order to assess IH as potential regulator of IBC aggressiveness. Gene array analysis of IBC cells following chronic IH (45-60 days) demonstrated increased expression of pro-metastatic genes of the extracellular matrix, such as tenascin-C (TNC; an essential factor of the metastatic niche) and matrix metalloproteinase 9 (MMP9), and of pro-inflammatory processes, such as cyclooxygenase-2 (COX-2). Investigating the oxidative stress-dependent regulation of TNC, we found a gradual sensitivity on mRNA and protein levels. Oxidative stress activated NF-E2-related factor 2 (Nrf2), c-Jun N-terminal kinase (JNK), c Jun and nuclear factor kappaB (NF-kappaB), but TNC upregulation was only dependent on NF-kappaB activation. Pharmacological inhibition of inhibitor of NF kappaB alpha (IkappaBalpha) phosphorylation as well as overexpression of IkappaBalpha prevented TNC, MMP9 and COX-2 induction, whereas the pro inflammatory cytokine interleukin-1beta (IL-1beta) increased their expression levels. Analysis of the gene array data showed NF-kappaB binding sites for 64% of all upregulated genes, linking NF-kappaB with IH-dependent regulation of pro metastatic gene expression in IBC cells. Our results provide a first link between intermittent hypoxia and pro-metastatic gene expression in IBC cells, revealing a putative novel mechanism for the high metastatic potential of IBC. PMID- 27717870 TI - Neonatal interventions differently affect maternal care quality and have sexually dimorphic developmental effects on corticosterone secretion. AB - Neonatal handling (H) and maternal separation (MS) both induce changes in maternal care, but the contribution of these changes to the behavioral and neurochemical outcomes of the offspring remains unclear, as studies often find opposite results concerning the frequency of maternal behaviors, particularly in the MS paradigm. In this study, behavior displayed by H, MS and non-handled (NH) Wistar rat dams were observed during the first 10days after birth. A tentative assessment of the quality of maternal care was made, using a previously reported score that reflects behavior fragmentation and inconsistency. Central oxytocin levels and hippocampal synaptic plasticity markers were also evaluated in dams, immediately after litter weaning. In adulthood, male and female offspring were subjected to a contextual stress-induced corticosterone challenge to provide further information on the impact of early interventions on neuroendocrine parameters. We found that while both H and MS interventions induced an increase in the amount of pup-directed behavior, MS dams displayed a more fragmented and inconsistent pattern of care, reflecting poorer maternal care quality. Interestingly, an increase in oxytocin levels was observed only in H dams. While H offspring did not differ from NH, MS males and females showed marked differences in corticosterone secretion compared to controls. Our results suggest that briefly removing the pups from the nest alters maternal care quantity but not quality and increases central oxytocin, while long separations appear to increase low quality maternal care and change neuroendocrine responses in adult offspring in a sex-specific manner. PMID- 27717871 TI - Effects of multiple brief exposures to trauma-associated cues on traumatized resilient and vulnerable rats. AB - Intrusive re-experiencing of a trauma is a core symptom in post-traumatic stress disorder (PTSD), and is often triggered by contextual cues associated with the event. It is not yet established if intrusive re-experiencing is the consequence of PTSD, or if it could contribute to the development of PTSD following a traumatic event. The present study (1) examined the impact of repeated brief re exposures to trauma reminders on the strength of PTSD-like symptoms, as well as on their time-development and (2) investigated the reactivity over time to these cues in trauma resilient and vulnerable rats, defined on the basis of the PTSD like symptoms they demonstrated. Rats were exposed to a Single Prolonged Stress, combining three different stresses (2-h restraint, 20-min forced swim and CO2 unconsciousness) delivered together with tone and odor cues and preceded by an inhibitory avoidance conditioning or a control procedure. During the following two weeks, reminded rats were briefly re-exposed to trauma-associated cues either 4 or 8 times. The results indicated that 4 re-exposures to the same cue strengthened PTSD-like symptoms (anxiety, arousal, fear to trauma-cue). However 8 re-exposures to similar or different trauma-cues did not alter PTSD-like symptoms and led to a rapid extinction of the fear reactivity to these cues. The present results further indicated that shortly after trauma, both resilient and vulnerable rats strongly reacted to trauma-associated cues, while only vulnerable rats reacted long after the trauma, suggesting a slower loss of fear responses to trauma cues in these rats. We concluded that re-experiencing may participate in, but cannot be solely responsible for, the development of long-term PTSD effects. PMID- 27717861 TI - Epidemiological characteristics, practice of ventilation, and clinical outcome in patients at risk of acute respiratory distress syndrome in intensive care units from 16 countries (PRoVENT): an international, multicentre, prospective study. AB - BACKGROUND: Scant information exists about the epidemiological characteristics and outcome of patients in the intensive care unit (ICU) at risk of acute respiratory distress syndrome (ARDS) and how ventilation is managed in these individuals. We aimed to establish the epidemiological characteristics of patients at risk of ARDS, describe ventilation management in this population, and assess outcomes compared with people at no risk of ARDS. METHODS: PRoVENT (PRactice of VENTilation in critically ill patients without ARDS at onset of ventilation) is an international, multicentre, prospective study undertaken at 119 ICUs in 16 countries worldwide. All patients aged 18 years or older who were receiving mechanical ventilation in participating ICUs during a 1-week period between January, 2014, and January, 2015, were enrolled into the study. The Lung Injury Prediction Score (LIPS) was used to stratify risk of ARDS, with a score of 4 or higher defining those at risk of ARDS. The primary outcome was the proportion of patients at risk of ARDS. Secondary outcomes included ventilatory management (including tidal volume [VT] expressed as mL/kg predicted bodyweight [PBW], and positive end-expiratory pressure [PEEP] expressed as cm H2O), development of pulmonary complications, and clinical outcomes. The PRoVENT study is registered at ClinicalTrials.gov, NCT01868321. The study has been completed. FINDINGS: Of 3023 patients screened for the study, 935 individuals fulfilled the inclusion criteria. Of these critically ill patients, 282 were at risk of ARDS (30%, 95% CI 27-33), representing 0.14 cases per ICU bed over a 1-week period. VT was similar for patients at risk and not at risk of ARDS (median 7.6 mL/kg PBW [IQR 6.7-9.1] vs 7.9 mL/kg PBW [6.8-9.1]; p=0.346). PEEP was higher in patients at risk of ARDS compared with those not at risk (median 6.0 cm H2O [IQR 5.0-8.0] vs 5.0 cm H2O [5.0-7.0]; p<0.0001). The prevalence of ARDS in patients at risk of ARDS was higher than in individuals not at risk of ARDS (19/260 [7%] vs 17/556 [3%]; p=0.004). Compared with individuals not at risk of ARDS, patients at risk of ARDS had higher in-hospital mortality (86/543 [16%] vs 74/232 [32%]; p<0.0001), ICU mortality (62/533 [12%] vs 66/227 [29%]; p<0.0001), and 90-day mortality (109/653 [17%] vs 88/282 [31%]; p<0.0001). VT did not differ between patients who did and did not develop ARDS (p=0.471 for those at risk of ARDS; p=0.323 for those not at risk). INTERPRETATION: Around a third of patients receiving mechanical ventilation in the ICU were at risk of ARDS. Pulmonary complications occur frequently in patients at risk of ARDS and their clinical outcome is worse compared with those not at risk of ARDS. There is potential for improvement in the management of patients without ARDS. Further refinements are needed for prediction of ARDS. FUNDING: None. PMID- 27717869 TI - Withaferin A induces Nrf2-dependent protection against liver injury: Role of Keap1-independent mechanisms. AB - Small molecules of plant origin offer presumptively safe opportunities to prevent carcinogenesis, mutagenesis and other forms of toxicity in humans. However, the mechanisms of action of such plant-based agents remain largely unknown. In recent years the stress responsive transcription factor Nrf2 has been validated as a target for disease chemoprevention. Withania somnifera (WS) is a herb used in Ayurveda (an ancient form of medicine in South Asia). In the recent past, withanolides isolated from WS, such as Withaferin A (WA) have been demonstrated to be preventive and therapeutic against multiple diseases in experimental models. The goals of this study are to evaluate withanolides such as WA as well as Withania somnifera root extract as inducers of Nrf2 signaling, to probe the underlying signaling mechanism of WA and to determine whether prevention of acetaminophen (APAP)-induced hepatic toxicity in mice by WA occurs in an Nrf2 dependent manner. We observed that WA profoundly protects wild-type mice but not Nrf2-disrupted mice against APAP hepatotoxicity. WA is a potent inducer of Nrf2 dependent cytoprotective enzyme expression both in vivo and in vitro. Unexpectedly, WA induces Nrf2 signaling at least in part, in a Keap1-independent, Pten/Pi3k/Akt-dependent manner in comparison to prototypical Nrf2 inducers, sulforaphane and CDDO-Im. The identification of WA as an Nrf2 inducer that can signal through a non-canonical, Keap1-independent pathway provides an opportunity to evaluate the role of other regulatory partners of Nrf2 in the dietary and pharmacological induction of Nrf2-mediated cytoprotection. PMID- 27717872 TI - Graft Transit Time Has No Effect on Outcome of Unrelated Donor Hematopoietic Cell Transplants Performed in Australia and New Zealand: A Study from the Australasian Bone Marrow Transplant Recipient Registry. AB - A previous study found that platelet recovery and mortality were worse in recipients of myeloablative bone marrow transplants where graft transit times were longer than 20 hours. This retrospective study of unrelated myeloablative allogeneic transplantation performed within Australia and New Zealand analyzed transplant outcomes according to graft transit times. Of 233 assessable cases, 76 grafts (33%) were sourced from bone marrow (BM) and 157 (67%) from peripheral blood. Grafts sourced from Australia and New Zealand (47% of total) were associated with a median transit time of 6 hours versus 32 hours for overseas sourced grafts (53% of total). Graft transit temperature was refrigerated in 85%, ambient in 6%, and unknown in 9% of cases, respectively. Graft transit times had no significant effect on neutrophil or platelet engraftment, treatment-related mortality, overall survival, and incidence of acute or chronic graft-versus-host disease. Separate analysis of BM grafts, although of reduced power, also showed no significant difference in either neutrophil or platelet engraftment or survival between short and longer transport times. This study gives reassurance that both peripheral blood stem cell and especially BM grafts subjected to long transit times and transported at refrigerated temperatures may not be associated with adverse recipient outcomes. PMID- 27717873 TI - Microbial signatures of oral dysbiosis, periodontitis and edentulism revealed by Gene Meter methodology. AB - Conceptual models suggest that certain microorganisms (e.g., the "red" complex) are indicative of a specific disease state (e.g., periodontitis); however, recent studies have questioned the validity of these models. Here, the abundances of 500+ microbial species were determined in 16 patients with clinical signs of one of the following oral conditions: periodontitis, established caries, edentulism, and oral health. Our goal was to determine if the abundances of certain microorganisms reflect dysbiosis or a specific clinical condition that could be used as a 'signature' for dental research. Microbial abundances were determined by the analysis of 138,718 calibrated probes using Gene Meter methodology. Each 16S rRNA gene was targeted by an average of 194 unique probes (n=25nt). The calibration involved diluting pooled gene target samples, hybridizing each dilution to a DNA microarray, and fitting the probe intensities to adsorption models. The fit of the model to the experimental data was used to assess individual and aggregate probe behavior; good fits (R2>0.90) were retained for back-calculating microbial abundances from patient samples. The abundance of a gene was determined from the median of all calibrated individual probes or from the calibrated abundance of all aggregated probes. With the exception of genes with low abundances (<2 arbitrary units), the abundances determined by the different calibrations were highly correlated (r~1.0). Seventeen genera were classified as 'signatures of dysbiosis' because they had significantly higher abundances in patients with periodontitis and edentulism when contrasted with health. Similarly, 13 genera were classified as 'signatures of periodontitis', and 14 genera were classified as 'signatures of edentulism'. The signatures could be used, individually or in combination, to assess the clinical status of a patient (e.g., evaluating treatments such as antibiotic therapies). Comparisons of the same patient samples revealed high false negatives (45%) for next generation-sequencing results and low false positives (7%) for Gene Meter results. PMID- 27717874 TI - Pharmaceutical development of novel lactate-based 6-fluoro-l-DOPA formulations. AB - 6-[18F]fluoro-l-dihydroxyphenylalanine (18F-DOPA) is a diagnostic positron emission tomography (PET) agent, which has been used for decades in imaging the loss of dopaminergic neurons in Parkinson's disease, and more recently to detect, stage and restage neuroendocrine tumors (NETs) and to search for recurrence of viable glioma tissue. The commercially available 18F-DOPA PET radiopharmaceutical for diagnostic use in European Union countries, is formulated in an aqueous solution of acetic acid (1.05mg/mL) and has the disadvantages that, immediately before injection, the pH must be adjusted to 4.0-5.0 by the addition of a sterile solution of sodium bicarbonate (84mg/mL) causing a light and transient burning sensation at the injection site. To overcome these drawbacks, preformulation studies were accomplished to confirm that F-DOPA degradation was affected by pH. Hence, two formulations of F-DOPA, namely ND1 and ND2, were prepared maintaining the pH=5.0 using 1mM l-(+)-lactate buffer, excluding oxygen, and incorporating in the formula the chelating agent Na2EDTA (1mM). F-DOPA oxygen exposure, the presence of free metal cations in formulation and high pH values seem to promote F-DOPA degradation. The resulting formulations proved to guarantee the chemical stability of F-DOPA in solution at pH5.0, value also compatible with the direct infusion. In vitro cell viability tests on mouse skeletal muscle fibers, renal tsa201 and neuronal SH-SY5Y cell lines, and in vivo studies in rats reported elsewhere, showed cell tolerability to the new F-DOPA formulations providing the basis for their further in vivo evaluation. PMID- 27717875 TI - Inhibition of YAP signaling contributes to senescence of hepatic stellate cells induced by tetramethylpyrazine. AB - Accumulating evidence indicates that hepatic stellate cells (HSCs) are the central mediators and major effectors in the development of hepatic fibrosis. It is well-known that regulation of cell proliferation and apoptosis are potential strategies to block the activation of HSCs. Recently, several studies have revealed that induction of HSC senescence could prevent and cure the liver fibrosis. In our previous work, we have demonstrated that the natural product tetramethylpyrazine (TMP) could inhibit the activation of HSCs and ameliorate hepatic fibrosis. The aim of this study was to identify a new role of TMP in the regulation of activated HSC senescence and to elucidate the underlying mechanisms. In this study, our data showed that TMP could promote HSC senescence in vivo and in vitro. Moreover, TMP affected the cell cycle and telomerase activity. We further demonstrated that P53 siRNA or P53 pharmacological inhibitor PFT-alpha abrogated the TMP-induced HSC senescence in vitro. Meanwhile, similar results were obtained in vivo. Further studies indicated that TMP promoted the expression of P53 through a YAP inhibition-dependent mechanism. Moreover, silencing YAP enhanced TMP induction of activated HSC senescence. Collectively, our results suggested that TMP inhibited the activation of HSCs by inducing senescence and had therapeutic implication for the treatment of liver fibrosis. PMID- 27717876 TI - Programmed death (PD)-1 attenuates macrophage activation and brain inflammation via regulation of fibrinogen-like protein 2 (Fgl-2) after intracerebral hemorrhage in mice. AB - Neuroinflammation plays an important role in the recovery of brain injury in ICH. Macrophage is the major executor in the neuroinflammation and initiates neurological defects. Programmed death 1 (PD-1) delivers inhibitory signals that regulate the balance between T cell activation, tolerance, and immunopathology. PD-1 expression by macrophages plays a pathologic role in the innate inflammatory response. However, the exact role of PD-1 on inflammatory responses following ICH has not been well identified. In this experiment, PD-1 KO (PD-1 -/-) ICH mice and Wild-type (WT) ICH mice were caused by intracranial injection of type IV collagenase. The level of macrophage activation, inflammatory cytokines and fibrinogen-like protein 2 (Fgl-2) were detected using immunofluorescence staining and ELISA assays. In addition, brain edema and neurological scores of ICH mice were also measured. Our data demonstrated that ICH promoted PD-1 expression of macrophage and enhanced inflammatory cytokines and Fgl-2 concentrations. PD-1 -/- mice exhibited significantly higher expression of the inflammatory cytokines which initiate Fgl-2, than did their wild-type (WT) littermates. As a result, macrophage activation, cerebral edema and neurological deficit scores of PD-1 -/- mice were higher. In conclusion, our data demonstrate that PD-1 plays a vital role in brain inflammation via regulation of Fgl-2 after ICH, and that manipulation of PD-1 might be a promising therapeutical target in ICH. PMID- 27717877 TI - 1,25-dihydroxyvitamin D3 down-modulates the production of proinflammatory cytokines and nitric oxide and enhances the phosphorylation of monocyte-expressed STAT6 at the recent-onset type 1 diabetes. AB - BACKGROUND: Type 1 diabetes (T1D) is associated with an imbalance between inflammation and repair. Recently, the biologically active form of vitamin D3, i.e. 1,25(OH)2D3, has been reported to have potent immunomodulatory effects on both innate and adaptive immune cells, as well as on the production of their specific cytokines. METHODS: We examined the effect of 1,25(OH)2D3 on the production of proinflammatory Th1/Th17 and anti-inflammatory Th2/Treg related cytokines, as well as on the phosphorylation of monocyte-expressed STAT4 and STAT6 at the recent-onset human T1D. RESULTS: The levels of IFN-gamma, IL-17 and nitric oxide (NO) production were significantly increased in peripheral blood mononuclear cells (PBMCs) from patients with T1D compared to controls. Similarly, STAT4 tyrosine phosphorylation (p-STAT4, Tyr693) levels were significantly increased in monocytes from patients when compared to controls. Conversely, the levels of IL-4, IL-10 and p-STAT6 (Tyr641) were significantly decreased in type 1 diabetic patients than in controls. Treatment with 1,25(OH)2D3 resulted in significant up-regulation of IL-4, IL-10, arginase activity, and p-STAT6 and, conversely, down-regulation of IFN-gamma, IL-17 and NO production levels, as well as p-STAT4. Additionally, 1,25(OH)2D3 significantly enhanced Treg-to-Th17 ratio, and induced a significant decrease in Th1-to-Th2, NO production-to-arginase activity and p-STAT4-to-p-STAT6 ratios. CONCLUSIONS: Our study suggests that the biologically active form of vitamin D can reverse the activation of inflammatory pathways at the onset of T1D. Additionally, its immunomodulation properties may vary depending on the overall patterns of cytokines. From a therapeutic point of view, vitamin D may potentially be suggested as an immunological adjuvant and a potential anti-inflammatory agent in individuals at risk of T1D. PMID- 27717878 TI - Insights into selenite reduction and biogenesis of elemental selenium nanoparticles by two environmental isolates of Burkholderia fungorum. AB - Microorganisms capable of transforming toxic selenium oxyanions into non-toxic elemental selenium (Se degrees ) may be considered as biocatalysts for the production of selenium nanoparticles (SeNPs), eventually exploitable in different biotechnological applications. Two Burkholderia fungorum strains (B. fungorum DBT1 and B. fungorum 95) were monitored during their growth for both capacity and efficiency of selenite (SeO32-) reduction and elemental selenium formation. Both strains are environmental isolates in origin: B. fungorum DBT1 was previously isolated from an oil refinery drainage, while B. fungorum 95 has been enriched from inner tissues of hybrid poplars grown in a soil contaminated by polycyclic aromatic hydrocarbons. Our results showed that B. fungorum DBT1 is able to reduce 0.5mM SeO32- to Se degrees when cultured aerobically in liquid medium at 27 degrees C, while B. fungorum 95 can reduce more than 1mM SeO32- to Se degrees within 96h under the same growth conditions, with the appearance of SeNPs in cultures of both bacterial strains. Biogenic SeNPs were spherical, with pH dependent charge and an average hydrodynamic diameter of 170nm and 200nm depending on whether they were produced by B. fungorum 95 or B. fungorum DBT1, respectively. Electron microscopy analyses evidenced that Se nanoparticles occurred intracellularly and extracellularly. The mechanism of SeNPs formation can be tentatively attributed to cytoplasmic enzymatic activation mediated by electron donors. Biogenic nanoparticles were then probably released outside the bacterial cells as a consequence of a secretory process or cell lysis. Nevertheless, formation of elemental selenium nanoparticles under aerobic conditions by B. fungorum DBT1 and B. fungorum 95 is likely due to intracellular reduction mechanisms. Biomedical and other high tech sectors might exploit these biogenic nanoparticles in the near future, once fully characterized and tested for their multiple properties. PMID- 27717879 TI - Unravelling cortico-hypothalamic pathways regulating unconditioned fear-induced antinociception and defensive behaviours. AB - The medial prefrontal cortex can influence unconditioned fear-induced defensive mechanisms organised by diencephalic neurons that are under tonic GABAergic inhibition. The posterior hypothalamus (PH) is involved with anxiety- and panic attack-like responses. To understand this cortical mediation, our study characterised anterior cingulate cortex (ACC)-PH pathways and investigated the effect of ACC local inactivation with lidocaine. We also investigated the involvement of PH ionotropic glutamate receptors in the defensive behaviours and fear-induced antinociception by microinjecting NBQX (an AMPA/kainate receptor antagonist) and LY235959 (a NMDA receptor antagonist) into the PH. ACC pretreatment with lidocaine decreased the proaversive effect and antinociception evoked by GABAA receptor blockade in the PH, which suggests that there may be descending excitatory pathways from this cortical region to the PH. Microinjections of both NBQX and LY235959 into the PH also attenuated defensive and antinociceptive responses. This suggests that the blockade of AMPA/kainate and NMDA receptors reduces the activity of glutamatergic efferent pathways. Both inputs from the ACC to the PH and glutamatergic hypothalamic short links disinhibited by intra-hypothalamic GABAA receptors blockade are potentially implicated. Microinjection of a bidirectional neurotracer in the PH showed a Cg1 PH pathway and PH neuronal reciprocal connections with the periaqueductal grey matter. Microinjections of an antegrade neurotracer into the Cg1 showed axonal fibres and glutamatergic vesicle-immunoreactive terminal boutons surrounding both mediorostral-lateroposterior thalamic nucleus and PH neuronal perikarya. These data suggest a critical role played by ACC-PH glutamatergic pathways and AMPA/kainate and NMDA receptors in the panic attack-like reactions and antinociception organised by PH neurons. PMID- 27717880 TI - 3-Furan-2-yl-N-p-tolyl-acrylamide, a positive allosteric modulator of the alpha7 nicotinic receptor, reverses schizophrenia-like cognitive and social deficits in rats. AB - The cognitive impairments and negative symptoms experienced by schizophrenia patients still await effective treatment. Alpha7 nicotinic acetylcholine receptors (alpha7 nAChRs) have gain considerable attention in this regard. It has been recently proposed that positive allosteric modulators (PAMs) of alpha7 nAChRs may represent an alternative strategy to that based on orthosteric agonists. The aim of the present study is to evaluate the efficacy of PAM-2 (3 furan-2-yl-N-p-tolyl-acrylamide) against cognitive deficits and negative-like symptoms in a rat model of schizophrenia based on administration of ketamine, a NMDAR antagonist. The activity of PAM-2 was compared to that elicited by DMXBA, an alpha7 nAChR partial agonist. For this purpose, the attentional set-shifting task (ASST) and the novel object recognition task (NORT) were used. The efficacies of PAM-2 and DMXBA against ketamine-induced social withdrawal were assessed using the social interaction test (SIT). The results demonstrated that PAM-2 and DMXBA ameliorated ketamine-induced cognitive impairments on the ASST and NORT as well as produced pro-social activities in the SIT. Moreover, the co administration of inactive doses of PAM-2 and antipsychotic drugs, clozapine or risperidone, reversed ketamine-induced deficits. The present findings provide further support for the concept that alpha7-PAMs could be used either alone or in combination with antipsychotics for schizophrenia therapy. PMID- 27717882 TI - Pain modulation from the brain during diabetic neuropathy: Uncovering the role of the rostroventromedial medulla. AB - Diabetic neuropathy has a profound impact in the quality of life of patients who frequently complain of pain. The mechanisms underlying diabetic neuropathic pain (DNP) are no longer ascribed only to damage of peripheral nerves. The effects of diabetes at the central nervous system are currently considered causes of DPN. Management of DNP may be achieved by antidepressants that act on serotonin (5-HT) uptake, namely specific serotonin reuptake inhibitors. The rostroventromedial medulla (RVM) is a key pain control center involved in descending pain modulation at the spinal cord through local release of 5-HT and plays a peculiar role in the balance of bidirectional control (i.e. inhibitory and facilitatory) from the brain to the spinal cord. This review discusses recently uncovered neurobiological mechanisms that mediate nociceptive modulation from the RVM during diabetes installation. In early phases of the disease, facilitation of pain modulation from the RVM prevails through a triplet of mechanisms which include increase in serotonin expression at the RVM and consequent rise of serotonin levels at the spinal cord and upregulation of local facilitatory 5HT3 receptors, enhancement of spontaneous activity of facilitatory RVM neurons and up regulation of the expression of transient receptor potential vanilloid type 1 (TRPV1) receptor. With the progression of diabetes the alterations in the RVM increase dramatically, with oxidative stress and neuronal death associated to microglia-mediated inflammation. In a manner similar to other central areas, like the thalamus, the RVM is likely to be a "pain generator/amplifier" during diabetes, accounting to increase DNP. Early interventions in DNP prevention using strategies that simultaneously tackle the exacerbation of 5-HT3 spinal receptors and of microglial RVM activity, namely those that increase the levels of anti inflammatory cytokines, should be considered in the future of DNP treatment.

AB - Breakdown of neuro-glial N-acetyl-aspartate (NAA) metabolism results in the failure of developmental myelination, manifest in the congenital pediatric leukodystrophy Canavan disease caused by mutations to the sole NAA catabolizing enzyme aspartoacylase. Canavan disease is a major point of focus for efforts to define NAA function, with available evidence suggesting NAA serves as an acetyl donor for fatty acid synthesis during myelination. Elevated NAA is a diagnostic hallmark of Canavan disease, which contrasts with a broad spectrum of alternative neurodegenerative contexts in which levels of NAA are inversely proportional to pathological progression. Recently generated data in the nur7 mouse model of Canavan disease suggests loss of aspartoacylase function results in compromised energetic integrity prior to oligodendrocyte death, abnormalities in myelin content, spongiform degeneration, and motor deficit. The present study utilized a next-generation "oligotropic" adeno-associated virus vector (AAV-Olig001) to quantitatively assess the impact of aspartoacylase reconstitution on developmental myelination. AAV-Olig001-aspartoacylase promoted normalization of NAA, increased bioavailable acetyl-CoA, and restored energetic balance within a window of postnatal development preceding gross histopathology and deteriorating motor function. Long-term effects included increased oligodendrocyte numbers, a global increase in myelination, reversal of vacuolation, and rescue of motor function. Effects on brain energy observed following AAV-Olig001-aspartoacylase gene therapy are shown to be consistent with a metabolic profile observed in mild cases of Canavan disease, implicating NAA in the maintenance of energetic integrity during myelination via oligodendroglial aspartoacylase. PMID- 27717883 TI - Mouse models of ageing and their relevance to disease. AB - Ageing is a process that gradually increases the organism's vulnerability to death. It affects different biological pathways, and the underlying cellular mechanisms are complex. In view of the growing disease burden of ageing populations, increasing efforts are being invested in understanding the pathways and mechanisms of ageing. We review some mouse models commonly used in studies on ageing, highlight the advantages and disadvantages of the different strategies, and discuss their relevance to disease susceptibility. In addition to addressing the genetics and phenotypic analysis of mice, we discuss examples of models of delayed or accelerated ageing and their modulation by caloric restriction. PMID- 27717884 TI - Identification of bacterial pathogens from formalin-fixed, paraffin-embedded tissues by using 16S sequencing: retrospective correlation of results to clinicians' responses. AB - 16S sequencing on formalin-fixed, paraffin-embedded (FFPE) material has been used to identify bacteria when culture-based phenotyping techniques have not worked. The objective of this study was to determine how frequently 16S sequencing used in FFPE material was helpful to clinicians in the diagnosis and treatment of infectious diseases. Requests for testing occurred upon consultation between an infectious disease pathologist and a surgical pathologist or an infectious disease physician. A selected paraffin block from each case was referred for 16S sequencing. Retrospectively, we correlated clinical history and management decisions on 27 cases that were tested by paneubacterial 16S sequencing. Samples included 24 surgical specimens, 1 autopsy, and 2 cytology blocks. Seventeen (63%) of the 27 cases had a positive 16S sequencing. Acute inflammation was present in 10 of these cases, and organisms were observed using special stains in 3. In 11 (65%) of the 17 cases, clinicians considered the organism identified by 16S sequencing to be the cause or possible cause of the infectious process. Organisms included common (Citrobacter) and fastidious bacteria (Haemophilus, Fusobacterium). In 3 cases, clinicians changed antibiotic treatment based on the bacteria identified, whereas in 8 (including 2 where no organism was found), clinicians continued the antibiotic treatment. The use of 16S sequencing on FFPE identified specific bacteria even when organisms were not observed histopathologically. 16S results had an impact in infectious disease management decisions. PMID- 27717885 TI - Myxoid leiomyosarcoma of the uterus: a clinicopathological and immunohistochemical study of 10 cases. AB - Uterine myxoid leiomyosarcoma (MLMS) is a rare tumor that requires modified diagnostic criteria compared with conventional leiomyosarcoma. We analyzed the clinicopathological and immunohistochemical features of 10 MLMS cases from a single institution. Nine of 10 MLMSs showed an invasive border, and 2 of 10 had vascular invasion. Seven cases exhibited low-grade nuclear features, low mitotic counts (median, 2/10 high-power fields), and no tumor cell necrosis. They were all at International Federation of Gynecology and Obstetrics stage I. Two recurred at the vaginal vault at 38 and 61 months, respectively. In contrast, 3 MLMSs with high-grade nuclei had a high mitotic rate (median, 12/10 high-power fields) and tumor cell necrosis (2/3). They were at an advanced International Federation of Gynecology and Obstetrics stage (IIIA-IVB). One had lung metastases at 6 months, and another died at 34 months. HMGA2 immunostaining was diffusely expressed in all MLMSs. Overexpression of p16 and IMP3 was present in 5 and 3 cases, respectively. We conclude that an invasive tumor border and p16 and/or IMP3 overexpression are helpful features in the diagnosis of MLMS. HMGA2 is a highly sensitive and useful marker for MLMS. MLMS might have 2 possible subtypes: high-grade, clinically aggressive MLMS and low-grade, relatively indolent tumors. PMID- 27717886 TI - The interplay between intracellular progesterone receptor and PKC plays a key role in migration and invasion of human glioblastoma cells. AB - Intracellular progesterone receptors (PRs) and protein kinases C (PKCs) are known regulators of cancer cell proliferation and metastasis. Both PRs and PKCs are found overexpressed in grade IV human astrocytomas, also known as glioblastomas, which are the most frequent and aggressive brain tumors. In the present study, we investigated whether PR activation by PKC induces the migration and invasion of glioblastoma derived cell lines and if PKCalpha and delta isoforms are involved in PR activation. We observed that PKC activation with tetradecanoylphorbol acetate (TPA) increases the migration and invasion capacity of two human glioblastoma derived human cell lines (U251 MG and U87) and that the treatment with the PR receptor antagonist RU486 blocks these processes. Interestingly, the pharmacological inhibition of the isoenzymes PKCalpha and PKCdelta also resulted in a blocked PR transcriptional activity. Also, TPA-dependent PR activation increases the expression of progesterone-induced blocking factor (PIBF), a known PR target gene. These results hint to an existing cross-talk between PKCs and PRs in regulating the infiltration process of human glioblastomas. PMID- 27717887 TI - Emodin alleviates bleomycin-induced pulmonary fibrosis in rats. AB - Idiopathic pulmonary fibrosis (IPF) is a lethal lung disease with few treatment options and poor prognosis. Emodin, extracted from Chinese rhubarb, was found to be able to alleviate bleomycin (BLM)-induced pulmonary fibrosis, yet the underlying mechanism remains largely unknown. This study aimed to further investigate the effects of emodin on the inflammation and fibrosis of BLM-induced pulmonary fibrosis and the mechanism involved in rats. Our results showed that emodin improved pulmonary function, reduced weight loss and prevented death in BLM-treated rats. Emodin significantly relieved lung edema and fibrotic changes, decreased collagen deposition, and suppressed the infiltration of myofibroblasts [characterized by expression of alpha-smooth muscle actin (alpha-SMA)] and inflammatory cells (mainly macrophages and lymphocytes). Moreover, emodin reduced levels of TNF-alpha, IL-6, TGF-beta1 and heat shock protein (HSP)-47 in the lungs of BLM-treated rats. In vitro, emodin profoundly inhibited TGF-beta1-induced alpha-SMA, collagen IV and fibronectin expression in human embryo lung fibroblasts (HELFs). Emodin also inhibited TGF-beta1-induced Smad2/3 and STAT3 activation, indicating that Smad2/3 and STAT3 inactivation mediates emodin induced effects on TGF-beta1-induced myofibroblast differentiation. These results suggest that emodin can exert its anti-fibrotic effect via suppression of TGF beta1 signaling and subsequently inhibition of inflammation, HSP-47 expression, myofibroblast differentiation and extracellular matrix (ECM) deposition. PMID- 27717888 TI - New intronic splicing mutation in the LMNA gene causing progressive cardiac conduction defects and variable myopathy. AB - BACKGROUND: Most of mutations in the LMNA gene are unique and have been found in only a few unrelated families. The clinical interpretation of new genetic variants, especially beyond the coding area and canonical splice sites, is proving to be difficult and requires advanced investigation. METHODS: This study included patients with progressive cardiac conduction defects with neuromuscular involvement. The clinical evaluation included medical history and 24-h Holter monitoring. The genetic evaluation included mutation screening in the LMNA gene by the Sanger sequence. Sanger sequencing was followed by RT-PCR of the target fragment of cDNA. In silico modeling was performed with CCBulder and Modeller software. RESULTS: The diagnosis of limb-girdle muscular dystrophy type 1B (LGMD1B) was established. The new intronic variant c.513+45T>G was found in the LMNA gene in the proband and affected daughter. The insertion of 45bp was confirmed in the proband's cDNA. The structural and possible functional effects of the aberrant protein were predicted. CONCLUSIONS: Variant c.513+45T>G in the LMNA gene likely translates into the longer lamin A/C proteins with additional 15 amino acids. This variant is thought to be pathogenic. Intronic variants in the LMNA gene located beside canonic splice sites may be responsible for some genotype-negative cases with clinical phenotype of laminopathies. PMID- 27717889 TI - Ovar-DRB1 haplotypes *2001 and *0301 are associated with sheep growth and ewe lifetime prolificacy. AB - BACKGROUND: The major histocompatibility complex (MHC) is an organized cluster of tightly linked vertebrate genes with immunological and non-immunological functions. While the important MHC gene DRB1 has been examined in regard to many sheep infectious disease traits, only one study, based on microsatellite markers, has previously examined DRB1 and sheep production traits. Furthermore, to our knowledge no studies have examined DRB1 relationship with lifetime ewe prolificacy traits. Therefore, we analyzed association between the presence of DRB1 SNP haplotypes with internationally recognized standard names and production traits including growth and lifetime prolificacy in 370 Rambouillet, Columbia, and Polypay sheep. RESULTS: The DRB1 *2001 haplotype was associated with increased weaning and mature weights, as well as average daily gain (Sidak P<0.05; corrected for the number of haplotypes tested). Interestingly, the *2001 haplotype also showed a trend toward association with increased total number of lifetime lambs born (Sidak P=0.084) and number of lambs born alive (Sidak P=0.084). In contrast, the DRB1 *0301 haplotype was associated with decreased mature weight (Sidak P=0.01). CONCLUSIONS: Since the *2001 haplotype was present in all three breeds, these results suggest there is at least one functional mutation in the region that influences growth and prolificacy traits that may be broadly present across several breeds. Furthermore, combined use of the similar *2001 and *0301 multi-marker haplotypes that nonetheless have opposing directions of production trait associations will enhance mutation discovery in this region. If undesirable alleles for underlying mutations can be identified, selective pressure against one or a small number of undesirable alleles may improve production with limited impact on MHC genetic diversity and infectious disease susceptibility. PMID- 27717890 TI - Mitochondrial genome of Cricetulus migratorius (Rodentia: Cricetidae): Insights into the characteristics of the mitochondrial genome and the phylogenetic relationships of Cricetulus species. AB - Cricetulus migratorius is widely distributed in the northwestern arid regions of China. Here, the complete mitochondrial genome (mitogenome) of C. migratorius is reported, to our knowledge, for the first time. It was found to be 16,246bp in length, including 13 protein-coding genes (PCGs), 2 rRNA genes, 22 tRNA genes, and one control region, and showed characteristics typical of the vertebrate mitogenome. Comparative analyses of mitogenomes of Cricetulus species showed that hamster mitogenomes had the same arrangement and organizational structure. The base composition was AT-rich for all Cricetulus species. We elaborated the PCG sequence and found that the main differences in the start and stop codons were in the ND3 gene; the most frequently used codons were AUU (Ile) and CUA (Leu), and the AT-content at the 3rd position was lower than that at 1st and 2nd positions in all Cricetulus species. The second tRNAser had lost the dihydrouridine stem loop structure, which is found in all Cricetulus species. We also elucidated the structure of the control region (the extended termination associated sequences, the central conserved sequences, and the conserved sequence blocks), and the putative origin of replication for the light strand in all Cricetulus species. Based on mitogenome data with four reconstructed methods, phylogenetic trees showed high resolution in the divergent clades within Cricetulus. The results indicated that Cricetulus kamensis is at basal position, and has the earliest split among all Cricetulus species. Cricetulus griseus and Cricetulus longicaudatus clustered in a subclade, and were separate from C. kamensis. As previous studies have shown, Tscherskia triton is part of Cricetulus with high support value. It is noteworthy that C. migratorius is a young species, and has a close relationship with Allocricetulus eversmanni within Cricetulus, which is closer to the subgenus Allocricetulus. PMID- 27717891 TI - The rs767649 polymorphism in the promoter of miR-155 contributes to the decreased risk for cervical cancer in a Chinese population. AB - Genetic variants in miRNAs have attracted more and more attention these years because they are capable of altering miRNA function and/or expression, consequently affecting downstream biological pathways and disease risk. The rs767649 polymorphism, locating in the promoter of miR-155, was recently reported to be able to alter transcriptional activity of miR-155 and relate to lung cancer risk. In this study, we aimed to assess the relationship between rs767649 and cervical cancer (CC) risk. We investigated the association of rs767649 with CC risk in a two-stage case-control study with 1157 cases and 1280 controls. Genotyping was determined with TaqMan allelic discrimination method. The results showed that the rs767649 TT genotype was associated with a significantly reduced risk of CC in both test (549 cases and 603 controls), validation (608 cases and 677 controls) and combined sets [adjusted odds ratio (OR)=0.67, 95% confidence interval (CI)=0.51-0.87 for the combined set] compared with the AA/AT genotypes. Moreover, the association was more prominent among patients of age>49years and postmenopausal status (OR=0.56, 95% CI=0.38-0.83, and 0.60, 0.40-0.89, respectively) and patients with clinical stage I and II CC (OR=0.67, 95% CI=0.50 0.91, and 0.60, 0.40-0.92, respectively). Further analyses showed that miR-155 was overexpressed in the CC tissues as compared with normal tissues, suggesting an oncogenic role in CC. Luciferase assay indicated that the transition of A to T allele might lead to miR-155 downregulation at the transcriptional level. In conclusion, rs767649 might be a causal variant for CC susceptibility. PMID- 27717892 TI - Endoscopic cyclophotocoagulation for the treatment of glaucoma. AB - Endoscopic cyclophotocoagulation is laser treatment of the ciliary processes with direct visualization using a small video camera for the purpose of lowering intraocular pressure. It was traditionally reserved for management of refractory glaucoma, but is now increasingly used as an adjunct to cataract surgery in less advanced glaucoma. Here we present a review of the literature evaluating endoscopic cyclophotocoagulation's safety and efficacy in different forms of glaucoma with different degrees of progression. PMID- 27717893 TI - Education in ophthalmology over the past 60 years.

With clinical experience and leadership positions within ophthalmology and in broad medical organizations, this paper chronicles the evolution of educational practice and approaches for over a half century. PMID- 27717894 TI - Plasmodium falciparum isolates from patients with uncomplicated malaria promote endothelial inflammation. AB - The ability of Plasmodium falciparum infected erythrocytes (Pf-IEs) to activate endothelial cells has been described; however, the interaction of the endothelium with Pf-IEs field isolates from patients has been less characterized. Previous reports have shown that isolates alter the endothelial permeability and apoptosis. In this study, the adhesion of 19 uncomplicated malaria isolates to Human Dermal Microvascular Endothelial Cells (HDMEC), and their effect on the expression of ICAM-1 and proinflammatory molecules (sICAM-1, IL-6, IL-8, and MCP 1) was evaluated. P. falciparum isolates adhered to resting and TNFalpha activated HDEMC cells at different levels. All isolates increased the ICAM-1 expression on the membrane (mICAM-1) of HDMEC and increased the release of its soluble form (sICAM-1), as well the production of IL-6, IL-8 and MCP-1 by HDMEC with no signs of cell apoptosis. No correlation between parasite adhesion and production of cytokines was observed. In conclusion, isolates from uncomplicated malaria can induce a proinflammatory response in endothelial cells that may play a role during the initial inflammatory response to parasite infection; however, a continuous activation of the endothelium can contribute to pathogenesis. PMID- 27717895 TI - Quercetin protects against hair cell loss in the zebrafish lateral line and guinea pig cochlea. AB - Eighteen supplement drugs were screened using hair cells to determine a protective effect against the adverse effects of neomycin by using the zebrafish lateral line. The zebrafish were administered the supplement drugs 1 h before neomycin exposure. One hour later, animals were fixed in paraformaldehyde. Dose response curves were generated to evaluate the protective effect on hair cells. The screen identified 3 supplements (quercetin, catechin and tannic acid). Three minutes after exposure to neomycin, increased antioxidant activity was found in the lateral line hair cells, as determined by the analysis of oxidative stress. Quercetin decreases antioxidant activity. The identified drugs were also investigated to determine whether they protect the cochlea against noise-induced hearing loss in guinea pigs. The drugs were administered via the intraperitoneal route in the guinea pigs 3 days before and 4 days after noise exposure. Seven days after noise exposure (130-dB sound pressure level for 3 h), the auditory brainstem response threshold shifts were assessed. We observed that the auditory brainstem response threshold shift was significantly less in the quercetin group than in the vehicle control group. The results of our study indicate that screening drugs using zebrafish can determine additional protective drugs for the inner ear. PMID- 27717896 TI - Proteomic and physiological analyses of wheat seeds exposed to copper and iron nanoparticles. AB - To elucidate the role of Cu and Fe NPs on the yield of wheat varieties, a gel free proteomic technique was used. NPs were synthesized and characterized through zeta potential, EDX, and SEM. Spike length, number of grains per spike, and 1000 grain weight were increased in wheat varieties treated with 25ppm Cu and Fe NPs. On treatment with 25ppm Cu and Fe NPs, a total of 58, 121, and 25 proteins were changed in abundance in wheat seeds of galaxy-13, Pakistan-13, and NARC-11, respectively. In galaxy-13, exposure to Cu NPs increased proteins involved in starch degradation and glycolysis. Furthermore, the number of proteins related to starch degradation, glycolysis, and tricarboxylic acid cycle was increased in galaxy-13 on Fe NPs exposure. Proteins related to glycolysis and the tricarboxylic acid cycle was increased in Pakistan-13 and NARC-11 by Fe NPs exposure. The sugar content and SOD activity was increased in wheat seeds treated with Cu and Fe NPs. The Cu content was increased at 25ppm Cu NPs exposure in seeds of wheat varieties. These results suggest that Cu NPs improved stress tolerance in wheat varieties by mediating the process of starch degradation, glycolysis, and tricarboxylic acid cycle through NPs uptake.

PMID- 27717898 TI - Predicting postoperative morphine consumption in children. AB - BACKGROUND: Morphine is the most commonly used postoperative analgesic for moderate to severe pain in paediatric patients, but there is little research into predictive factors correlating with postoperative morphine consumption. METHODS: All patients undergoing surgery who received morphine postoperatively over eight months were prospectively enrolled. Data analysed included total morphine consumption to day 3, age, weight, type of surgery, ASA status, preoperative opioid administration, predicted postoperative pain intensity (according to French Society of Anaesthesiology and Intensive Care classification) and surgery duration. Two cohorts were constructed: the first over 6months to construct a statistical model and the second over 2months to validate the model. ANOVA univariate analyses and multivariate linear analysis were performed. RESULTS: One hundred and fifty-three patients were included in the construct cohort and 40 in the validation cohort. Multivariate analysis demonstrated that total morphine consumption through postoperative day 3 was independently increased by a decreased age, female gender, an increased duration of surgery and an increased morphine titration in PACU. Overall, the model explained 57% of morphine requirement variability. When the model was applied to the validation cohort, a significant correlation was demonstrated between observed and predicted values: r=0.67, P<0.0001. CONCLUSION: Age, gender, duration of surgery and doses of titrated morphine in PACU proved to be strong predictors of postoperative morphine consumption by day 3 during paediatric surgery. Knowledge of such factors may help clinicians to better manage postoperative pain in children. PMID- 27717899 TI - Postoperative complications after craniotomy for brain tumor surgery. AB - INTRODUCTION: After elective craniotomy for brain tumour surgery, patients are usually admitted to an intensive care unit (ICU) for monitoring. Our goal was to evaluate the incidence and timing of neurologic and non-neurologic postoperative complications after brain tumour surgery, to determine factors associated with neurologic events and to evaluate the timing and causes of ICU readmission. PATIENTS AND METHODS: This prospective, observational and analytic study enrolled 188 patients admitted to the ICU after brain tumour surgery. All postoperative clinical events during the first 24hours were noted and classified. Readmission causes and timing were also analysed. RESULTS: Twenty-one (11%) of the patients were kept sedated after surgery; the remaining 167 patients were studied. Thirty one percent of the patients presented at least one complication (25% with postoperative nausea and vomiting (PONV), 16% with neurologic complications). The occurrence of neurological complications was significantly associated with the absence of preoperative motor deficit and the presence of higher intraoperative bleeding. Seven patients (4%) were readmitted to the ICU after discharge; 43% (n=3) of them had a posterior fossa surgery. CONCLUSION: Postoperative complications, especially PONV, are frequent after brain tumour surgery. Moreover, 16% of patients presented a neurological complication, probably justifying the ICU postoperative stay for early detection. The absence of preoperative motor deficit and intraoperative bleeding seems to predict postoperative neurologic complications. Finally, patients may present complications after ICU discharge, especially patients with fossa posterior surgery, suggesting that ICU hospitalization may be longer in this type of surgery. PMID- 27717900 TI - Identification of a C-type lectin from tilapia (Oreochromis niloticus) and its functional characterization under low-temperature stress. AB - C-type lectin, which plays an important role in fish innate immunity, was cloned from tilapia and its functional characterization under low-temperature stress is reported. Its ORF is 453 bp, encoding 150 amino acids, and has a 5'UTR of 83 bp, a 3'UTR of 559 bp, and a poly (A) tail. The tilapia C-type lectin genomic DNA was acquired with a length of 5714 bp, containing six exons and five introns. Its promoter sequence was cloned and has a length of 2251 bp. The highest promoter activity occurs in the regulatory region (-900 bp to -450 bp). A hemagglutination assay of recombinant tilapia C-type lectin protein showed positive hemagglutination of rabbit and tilapia erythrocytes. RT-qPCR and western blot assays showed that its expression in the liver, spleen, and intestine were clearly affected by low-temperature stress. Thus, tilapia C-type lectin appear to be affected by abiotic stress, as well as by biological stress. PMID- 27717901 TI - Molecular characterization, expression analysis, and bactericidal activity of the derivative peptides of TFPI-1 and TFPI-2 in half-smooth tongue sole, Cynoglossus semilaevis. AB - Tissue factor pathway inhibitors (TFPIs) are Kunitz-type serine protease inhibitors that reversibly regulate the blood coagulation induced by tissue factor. TFPI family contain two members, TFPI-1 and TFPI-2. Recent studies have shown TFPI-1 and TFPI-2 also play important roles in innate immunity, however, the potential function of teleost TFPI are very limited. In this study, we characterized two TFPI (CsTFPI-1 and CsTFPI-2) molecules from half-smooth tongue sole (Cynoglossus semilaevis), examined their tissue distributions and expression patterns under pathogens stimulation as well as investigated the antibacterial activity of the C-terminal peptides. Quantitative real time RT-PCR analysis showed that constitutive CsTFPI-1 expression occurred, in increasing order, in head kidney, intestine, brain, spleen, liver, skin, gills, heart, and muscle; CsTFPI-2 was expressed, in increasing order, in the gills, intestine, skin, head kidney, liver, brain, spleen, muscle, and heart. Under Vibrio anguillarum, Streptococcus agalactiae and fish megalocytivirus stimulation, both CsTFPI-1 and CsTFPI-2 expression increased significantly in a manner that depended on the pathogen, tissue type, and infection stage, which suggested CsTFPI-1 and CsTFPI-2 play important roles in anti-bacterial and anti-viral infection. Finally, C terminal peptides of CsTFPI-1 and CsTFPI-2, were synthesized and proved to have antibacterial effect against Micrococcus luteus that were independent of host serum. Take together, these results indicate that CsTFPI-1 and CsTFPI-2 play important roles in antimicrobial immunity of this fish. PMID- 27717902 TI - Mx1 of black carp functions importantly in the antiviral innate immune response. AB - Mx (myxovirus resistance) is an important antiviral protein in the innate immune responses of vertebrates to microbial pathogens. In this study, we cloned and characterized Mx1 of black carp (Mylopharyngodon piceus). The full-length cDNA of black carp Mx1 (bcMx1) consists of 2781 nucleotides and the predicted bcMx1 protein contains 631 amino acids. bcMx1 contains a GTPase domain at the N terminnus, a "central interactive domain" in the middle and a GTPase effector domain at the C-terminus. bcMx1 mRNA was constitutively transcribed in all tissues tested, including the heart, liver, spleen, kidney, intestine, muscle, skin and gill; and bcMx1 mRNA levels increased in all but the gill after grass carp reovirus (GCRV) or viraemia of carp virus (SVCV) infection. Quantitative PCR analysis of Mylopharyngodon piceus fin (MPF) cells indicated that bcMx1 mRNA levels increased after GCRV or SVCV infection at different multiplicities of infection (MOI). Western blotting demonstrated that the molecular weight of bcMx1 is ~75 kDa and immunofluorescent staining data of both HeLa cells and EPC cells showed that bcMx1 is a cytosolic protein. EPC cells transfected with plasmid expressing bcMx1 showed increased antiviral activity against SVCV and GCRV. All our data suggest that bcMx1 is an antiviral protein in the innate immune response of the black carp. PMID- 27717903 TI - An isoflavonoid-enriched extract from Pueraria lobata (kudzu) root protects human umbilical vein endothelial cells against oxidative stress induced apoptosis. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Reactive oxygen species (ROS) mediate vascular cell dysfunction and lead to atherosclerosis and other chronic cardiovascular diseases. The root of Pueraria lobata (Willd.) Ohwi, also known as kudzu or Gegen (Chinese name), is one of the most important herbs in traditional Chinese medicine and has been widely used in the treatment of cardiovascular diseases, diabetes, osteonecrosis and neurodegradation diseases. In this study, an ethanol extract from kudzu root was prepared and the in vitro protective effect of the kudzu root extract (KUD) on human umbilical vein endothelial cells (HUVECs) was investigated. MATERIAL AND METHODS: An ethanol extract of dried kudzu root was purified with an AB-8 resin column, and the concentrations of puerarin, daidzin and daidzein in the KUD were determined using UV spectroscopy. HUVECs were pretreated with various concentrations of the KUD with or without rotenone and the viability was assessed by AlamarBlue cell viability assay. Next, HUVECs were pretreated with the KUD and then treated with rotenone, and the levels of ROS generation, apoptosis, and changes of the mitochondrial membrane potential (DeltaPsim) in HUVECs were measured using fluorescent staining assay and high content analysis. RESULTS: The contents of three major isoflavonoids (puerarin, daidzin and daidzein) were enriched by 7.75-27.51 fold in the extract. The KUD enhanced the proliferation of HUVECs, and protected HUVECs against rotenone induced oxidative stress and apoptosis. Additionally, the KUD prevented the loss of DeltaPsim in HUVECs stimulated by oxidative stress. CONCLUSION: We demonstrated that an isoflavonoid-rich extract prepared from kudzu root has the potential to act as a protector for vascular endothelial cells against intracellular ROS mediated apoptosis and mitochondrial damage. PMID- 27717905 TI - Anti-giardia activity and acute toxicity of a methanol extract of Senna racemosa bark. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Senna racemosa (Mill.) H.S. Irwin & Barneby (syn. Cassia racemosa Mill.) is a plant used in traditional Mayamedicinal practices to treat diarrhea. A methanol extract of S. racemosa bark has been shown to have in vitro activity against Giardia intestinalis. No studies of its efficacy and toxicity in in vivo models have been done. The present study objective was to analyze the activity of this methanol extract of S. racemosa bark against Giardia intestinalis trophozoites in experimentally infected mice, and evaluate its toxicological effects in rats. MATERIAL AND METHODS: S. racemosa was collected in Merida, Yucatan, Mexico (21 degrees 58'N, 89 degrees 36'W) in June 2005. The bark methanol extract was obtained and high performance liquid chromatography (HPLC DAD) was used to generate a constituent profile. In vivo anti-giardia activity was assayed with an experimental model of G. intestinalis infection in neonatal CD-1 mice. Nine doses ranging from 0.25-15mg extract/kg body weight were tested to determine the dose required to kill 50% of the trophozoites (ED50). An acute toxicity assay was run in which one of four single doses (200, 1000, 2000 and3000mg/kg body weight) was orally administered to adult Wistar rats. Animal weight, death rates, toxic effects and behavioral parameters were observed over a 14-d period. They were then euthanized and a necropsy performed. RESULTS: The S. racemosa bark extract inhibited growth of G. intestinalis (ED50=1.14mg/Kg) in neonatal CD-1 mice. No toxic or lethal effects were observed even at the highest dosage (3000mg/Kg), and neither were signs of toxicity observed in internal organs. The active compounds chrysophanol and physcion were present in the extract at a 1.76 ratio.

AB - ETHNOPHARMACOLOGICAL RELEVANCE: Citrullus lanatus ssp. vulgaris var. megalaspermus Lin et Chao, was also known as watermelon belongs to family Cucurbitaceae, variously used as healthy food and in the treatment of liver and lungs problems. Currently, Citrullus lanatus has become a major economic crop of medicinal and edible effects with regional characteristics. AIM: This study was designed to evaluate the hepatoprotective and antioxidant activity of the seed melon (Citrullus lanatus ssp. vulgaris var. megalaspermus Lin et Chao) extract (SME) against carbon tetrachloride (CCl4) induced hepatic fibrosis in mice. MATERIALS AND METHODS: In this study, mice were randomly divided into 7 groups, including normal control, model, silymarin tablets as the positive control, SME 100, 200, 400, and 800mg/kg. After 8 weeks, activities of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglycerides (TG), hyaluronic acid (HA) and laminin (LN) were checked. The levels of antioxidant enzymes such as superoxide dismutase (SOD), glutataion (GSH) and glutathione peroxidase (GSH-Px) were determined after SME administration. The hydroxyproline (HYP) levels, malondialdehyde (MDA) levels and histopathologic examinations of hepatocyte fibrosis were also determined. Additionally, effects of SME on alpha smooth muscle actin (alpha-SMA) and transforming growth factor beta-1(TGF-beta1) protein expressions were determined. RESULTS: We found that SME could significantly lower the serum levels of hepatic enzyme markers AST, ALT, HA and LN (P<0.01). Compared with the CCl4-only treatment group, levels of hepatic SOD and GSH-Px were significantly increased, and the MDA levels were remarkably decreased in mice treated by SME at medium dose (400mg/kg) and high dose (800mg/kg) (P<0.01). A histological examination of the liver showed that lesions, including necrosis, lymphocyte infiltration and fatty degeneration, were partially healed by treatment with SME. The results of protein expressions studies displayed that SME could inhibit alpha-SMA and TGF-beta1 protein expression (P<0.01). CONCLUSION: The present results suggested that protective effect of SME against CCl4-induced hepatic fibrosis may rely on its effect on reducing oxidative stress and improving drug metabolizing enzyme activity in liver. PMID- 27717906 TI - Evaluation of wound healing property of Caesalpinia mimosoides Lam. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Caesalpinia mimosoides Lam. is one of the important traditional folk medicinal plants in the treatment of skin diseases and wounds used by healers of Uttara Kannada district of Karnataka state (India). However scientific validation of documented traditional knowledge related to medicinal plants is an important path in current scenario to fulfill the increasing demand of herbal medicine. AIM OF THE STUDY: The study was carried out to evaluate the claimed uses of Caesalpinia mimosoides using antimicrobial, wound healing and antioxidant activities followed by detection of possible active bio constituents. MATERIALS AND METHODS: Extracts prepared by hot percolation method were subjected to preliminary phytochemical analysis followed by antimicrobial activity using MIC assay. In vivo wound healing activity was evaluated by circular excision and linear incision wound models. The extract with significant antimicrobial and wound healing activity was investigated for antioxidant capacity using DPPH, nitric oxide, antilipid peroxidation and total antioxidant activity methods. Total phenolic and flavonoid contents were also determined by Folin-Ciocalteu, Swain and Hillis methods. Possible bio-active constituents were identified by GC-MS technique. RP-UFLC-DAD analysis was carried out to quantify ethyl gallate and gallic acid in the plant extract. RESULTS: Preliminary phytochemical analysis showed positive results for ethanol and aqueous extracts for all the chemical constituents. The ethanol extract proved potent antimicrobial activity against both bacterial and fungal skin pathogens compared to other extracts. The efficacy of topical application of potent ethanol extract and traditionally used aqueous extracts was evidenced by the complete re epithelization of the epidermal layer with increased percentage of wound contraction in a shorter period. However, aqueous extract failed to perform a consistent effect in the histopathological assessment. Ethanol extract showed effective scavenging activity against DPPH and nitric oxide free radicals with an expressive amount of phenolic and moderate concentration of flavonoid contents. Ethyl gallate and gallic acid were found to be the probable bio-active compounds evidenced by GCMS and RP-UFLC-DAD analysis. CONCLUSION: The study revealed the significant antimicrobial, wound healing and antioxidant activities of tender parts of C. mimosoides and proved the traditional folklore knowledge. PMID- 27717909 TI - Silvering and swimming effects on aerobic metabolism and reactive oxygen species in the European eel. AB - Silvering, the last metamorphosis in the eel life cycle induces morphological and physiological modifications in yellow eels (sedentary stage). It pre-adapts them to cope with the extreme conditions they will encounter during their 6000-km spawning migration. A previous study showed that silver eels are able to cope with reactive oxygen species (ROS) over-production linked to an increase in aerobic metabolism during sustained swimming, but the question remains as to whether this mechanism is associated with silvering. A sustained swimming session decreased red muscle in vitro mitochondrial oxygen consumption (MO2) but increased ROS production in both eel stages. The swimming exercise used here was perhaps too intense to induce a stimulation of mitochondrial function or biogenesis even when antioxidant enzyme activities were unchanged. Pro oxidant/antioxidant imbalance by lipid peroxidation increased in yellow but significantly decreased in silver eels. The silvering process therefore appears to allow a pre-adaptation of red muscle radical metabolism to the demands of spawning migration. PMID- 27717907 TI - Standardization of the manufacturing procedure for Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Pinelliae Rhizoma (PR), the dried tuber of Pinellia ternata (Thunb.) Breit., is a traditional Chinese medicinal herb. It is commonly used for treating cancer, cough and phlegm. To treat cancer, Chinese medicine practitioners often use raw PR; while to treat cough and phlegm, they usually use Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine (PRZA, raw PR processed with ginger juice and alumen as adjuvant materials). Currently, the producing protocol of PRZA varies greatly among different places in China. This study aims to standardize the manufacturing procedure for PRZA. We also evaluated the impact of processing on the bioactivities and chemical profile of raw PR. MATERIALS AND METHODS: We used the orthogonal design to optimize the manufacturing procedure of PRZA at bench scale, and validated the optimized procedure in pilot-scale production. The MTT assay was used to compare the cytotoxicities of raw PR and PRZA in hepatocellular carcinoma HepG2 cells. Animal models (ammonia liquor-induced cough model and phenol red secretion model) were used to compare the antitussive and expectorant effects of raw PR and PRZA, respectively. The chemical profiles of raw PR and PRZA samples were compared using a newly developed ultra-performance liquid chromatography/quadrupole-time of-flight mass spectrometry (UPLC/Q-TOF-MS) method. RESULTS: The standardized manufacturing procedure for PRZA is as follows: soak raw PR in water until the center of the cut surface is devoid of a dry core, after that, boil the herb in water (for each 100kg raw PR, 12.5kg alumen and 25L freshly squeezed ginger juice are added) for 6h, and then take out and dry them. The cytotoxicity of PRZA was less potent than that of raw PR. Intragastric administration of raw PR or PRZA demonstrated antitussive and expectorant effects in mice. These effects of PRZA were more potent than that of raw PR at the dose of 3g/kg. By comparing the chemical profiles, we found that six peaks were lower, while nine other peaks were higher in PRZA than in raw PR. Six compounds corresponding to six individual changed peaks were tentatively identified by matching with empirical molecular formulae and mass fragments. CONCLUSION: The manufacturing procedure for PRZA was standardized. This protocol can be used for PRZA industrial production. The bioactivity assay results of raw PR and PRZA (produced using the standardized protocol) support the common practice for the clinical applications of these two decoction pieces. Moreover, raw PR and PRZA showed different chemical profiles. Further studies are warranted to establish the relationship between the alteration of chemical profiles and the changes of medicinal properties caused by processing. PMID- 27717908 TI - Actions of water extract from Cordyceps militaris in hyperuricemic mice induced by potassium oxonate combined with hypoxanthine. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Cordyceps militaris was recorded in the classic traditional Chinese medicine book with the main functions of "protecting liver and enhancing kidney functions", influencing serum uric acid levels. AIM OF STUDY: The aim is to investigate the hypouricemic effects and possible mechanism of C. militaris in hyperuricemic mice. MATERIALS AND METHODS: A water extract (WECM) was prepared by decocting C. militaris directly at 80 degrees C in water bath, followed by lyophilization. WECM at 50, 100 and 200mg/kg was orally administered to hyperuricemic mice induced by potassium oxonate and hypoxanthine combinedly and allopurinol (5mg/kg) was served as a positive control. RESULTS: WECM exhibited excellent hypouricemic activity, which could decrease the serum uric acid levels of the hyperuricemic mice (306MUmol/L) to 189, 184 and 162MUmol/L at different doses respectively (P<0.01), approaching the levels of normal mice (184MUmol/L). The urate transporter 1 (URAT1) protein levels of kidney at different doses of WECM were 28.15, 17.43, 9.03pg/mL respectively, much lower than that in the hyperuricemia group (93.45pg/mL, P<0.01); and suggested WECM may interact with URAT1. Docking simulations using modeled structure of URAT1 suggested that LYS145, ARG325, ARG477 and ASP168 of URAT1 are key functional residues of URAT1. Four active compounds in C. militaris were identified and their interaction energies with target were estimated between -200 and -400kcal/mol. CONCLUSIONS: These findings suggested that C. militaris produced significant hypouricemic actions and the hypouricemic effects of WECM may be attributed to the inhibitive effect of WECM on URAT1 protein levels. The results of blood urine nitrogen and serum creatinine levels and liver, kidney and spleen coefficients showed that WECM have no negative impacts on liver, renal and spleen functions. The screened four active compounds using molecular docking method deserve further investigation in other work. PMID- 27717910 TI - A case of constitutional trisomy 3 mosaicism in a teenage patient with mild phenotype. AB - Constitutional mosaicism for trisomy 3 is extremely rare, with only a few postnatally diagnosed cases reported in the literature. We report a case of constitutional trisomy 3 mosaicism in a 16-year-old female, who presented with chronic joint pain, easy bruising, joint hypermobility and dysmorphic features, including long, thin facies, over-folded dysplastic ears, and Pierre-Robin sequence (PRS) with cleft palate. The patient was small at birth, had cleft palate repair, developed chronic joint pain at age 12, and has a history of mild leukopenia and mild thrombocytopenia. Microarray analysis was consistent with a mosaic gain of an entire chromosome 3. FISH analysis of peripheral blood and buccal cells showed the presence of the supernumerary chromosome 3 in a low percentage of cells in both tissues, suggesting that the nondisjunction event occurred prior to the germ cell layer differentiation. Since trisomy 3 has been observed somatically in lymphoma, a Hematology/Oncology consultation was provided for the patient. The oncologist's evaluation for malignancy was unremarkable. A review of findings from other trisomy 3 patients reported in the literature reveals a diverse phenotypic spectrum and does not show a correlation between the proportion of abnormal cells observed in peripheral blood and the patients' clinical features or severity. This case demonstrates that the clinical presentation of an individual with trisomy 3 is highly individualized and the clinical course is difficult to predict. PMID- 27717911 TI - Fibrin structural and diffusional analysis suggests that fibers are permeable to solute transport. AB - : Fibrin hydrogels are promising carrier materials in tissue engineering. They are biocompatible and easy to prepare, they can bind growth factors and they can be prepared from a patient's own blood. While fibrin structure and mechanics have been extensively studied, not much is known about the relation between structure and diffusivity of solutes within the network. This is particularly relevant for solutes with a size similar to that of growth factors. A novel methodological approach has been used in this study to retrieve quantitative structural characteristics of fibrin hydrogels, by combining two complementary techniques, namely confocal fluorescence microscopy with a fiber extraction algorithm and turbidity measurements. Bulk rheological measurements were conducted to determine the impact of fibrin hydrogel structure on mechanical properties. From these measurements it can be concluded that variations in the fibrin hydrogel structure have a large impact on the rheological response of the hydrogels (up to two orders of magnitude difference in storage modulus) but only a moderate influence on the diffusivity of dextran solutes (up to 25% difference). By analyzing the diffusivity measurements by means of the Ogston diffusion model we further provide evidence that individual fibrin fibers can be semi-permeable to solute transport, depending on the average distance between individual protofibrils. This can be important for reducing mass transport limitations, for modulating fibrinolysis and for growth factor binding, which are all relevant for tissue engineering. STATEMENT OF SIGNIFICANCE: Fibrin is a natural biopolymer that has drawn much interest as a biomimetic carrier in tissue engineering applications. We hereby use a novel combined approach for the structural characterization of fibrin networks based on optical microscopy and light scattering methods that can also be applied to other fibrillar hydrogels, like collagen. Furthermore, our findings on the relation between solute transport and fibrin structural properties can lead to the optimized design of fibrin hydrogel constructs for controlled release applications. Finally, we provide new evidence for the fact that fibrin fibers may be permeable for solutes with a molecular weight comparable to that of growth factors. This finding may open new avenues for tailoring mass transport properties of fibrin carriers. PMID- 27717912 TI - Improving the fatigue performance of porous metallic biomaterials produced by Selective Laser Melting. AB - : This paper provides new insights into the fatigue properties of porous metallic biomaterials produced by additive manufacturing. Cylindrical porous samples with diamond unit cells were produced from Ti6Al4V powder using Selective Laser Melting (SLM). After measuring all morphological and quasi-static properties, compression-compression fatigue tests were performed to determine fatigue strength and to identify important fatigue influencing factors. In a next step, post-SLM treatments were used to improve the fatigue life of these biomaterials by changing the microstructure and by reducing stress concentrators and surface roughness. In particular, the influence of stress relieving, hot isostatic pressing and chemical etching was studied. Analytical and numerical techniques were developed to calculate the maximum local tensile stress in the struts as function of the strut diameter and load. With this method, the variability in the relative density between all samples was taken into account. The local stress in the struts was then used to quantify the exact influence of the applied post-SLM treatments on the fatigue life. A significant improvement of the fatigue life was achieved. Also, the post-SLM treatments, procedures and calculation methods can be applied to different types of porous metallic structures and hence this paper provides useful tools for improving fatigue performance of metallic biomaterials. STATEMENT OF SIGNIFICANCE: Additive Manufacturing (AM) techniques such as Selective Laser Melting (SLM) are increasingly being used for producing customized porous metallic biomaterials. These biomaterials are regularly used for biomedical implants and hence a long lifetime is required. In this paper, a set of post-built surface and heat treatments is presented that can be used to significantly improve the fatigue life of porous SLM-Ti6Al4V samples. In addition, a novel and efficient analytical local stress method was developed to accurately quantify the influence of the post-built treatments on the fatigue life. Also numerical simulation techniques were used for validation. The developed methods and techniques can be applied to other types of porous biomaterials and hence provide new and useful tools for improving and predicting the fatigue life of porous biomaterials. PMID- 27717913 TI - Surface phosphonation enhances hydroxyapatite coating adhesion on polyetheretherketone and its osseointegration potential. AB - : Polyetheretherketone (PEEK) has excellent mechanical properties, biocompatibility, chemical resistance and radiolucency, making it suitable for use as orthopedic implants. However, its surface is hydrophobic and bioinert, and surface modification is required to improve its bioactivity. In this work, we showed that grafting phosphonate groups via diazonium chemistry enhances the bioactivity of PEEK. Decreased contact angle indicated reduced hydrophobicity as a result of the treatment and X-ray photoelectron spectroscopy (XPS) confirmed the attachment of phosphonate groups to the surface. The surface treatment not only accelerated hydroxyapatite (HA) deposition after immersion in simulated body fluid but also significantly increased the adhesion strength of HA particles on PEEK. MC3T3-E1 cell viability, metabolic activity and deposition of calcium containing minerals were also enhanced by the phosphonation. After three months of implantation in a critical size calvarial defect model, a fibrous capsule surrounded untreated PEEK while no fibrous capsule was observed around the treated PEEK. Instead, mineral deposition was observed in the region between the treated PEEK implant and underlying bone. This work introduces a simple method to improve the potential of PEEK-based orthopedic implants. STATEMENT OF SIGNIFICANCE: We have introduced phosphonate groups on the surface of PEEK substrates using diazonium chemistry. Our results show that the treatment not only increased the adhesion strength of hydroxyapatite particles deposited on PEEK in vitro by approximately 40% compared to unmodified PEEK, but also improved the metabolic activity and mineralization of MC3T3-E1 cells. When implanted in cranial defects in rats, the phosphonate coating enhanced the osseointegration of PEEK by successfully preventing the formation of a fibrous capsule and favoring mineral deposition between the implant and the surrounding bone. This work introduces a simple method to improve the potential of PEEK-based orthopedic implants, particularly those with complex shapes. PMID- 27717914 TI - Reversibly pH-responsive polyurethane membranes for on-demand intravaginal drug delivery. AB - : To provide better protection for women against sexually transmitted infections, on-demand intravaginal drug delivery was attempted by synthesizing reversibly pH sensitive polyether-polyurethane copolymers using poly(ethylene glycol) (PEG) and 1,4-bis(2-hydroxyethyl)piperazine (HEP). Chemical structure and thermo characteristics of the synthesized polyurethanes were confirmed by attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), 1H-nuclear magnetic resonance (1H-NMR), and melting point testing. Membranes were cast by solvent evaporation method using the prepared pH-sensitive polyurethanes. The impact of varying pH on membrane swelling and surface morphology was evaluated via swelling ratio change and scanning electron microscopy (SEM). The prepared pH responsive membranes showed two times higher swelling ratio at pH 4 than pH 7 and pH-triggered switchable surface morphology change. The anionic anti-inflammatory drug diclofenac sodium (NaDF) was used as a model compound for release studies. The prepared pH-responsive polyurethane membranes allowed continuous NaDF release for 24h and around 20% release of total NaDF within 3h at pH 7 but little-to-no drug release at pH 4.5. NaDF permeation across the prepared membranes demonstrated a reversible pH-responsiveness. The pH-responsive polyurethane membranes did not show any noticeable negative impact on vaginal epithelial cell viability or induction of pro-inflammatory cytokine production compared to controls. Overall, the non-cytotoxic HEP-based pH-responsive polyurethane demonstrated its potential to be used in membrane-based implants such as intravaginal rings to achieve on-demand "on-and-off" intravaginal drug delivery. STATEMENT OF SIGNIFICANCE: A reversible and sharp switch between "off" and "on" drug release is achieved for the first time through new pH-sensitive polyurethane membranes, which can serve as window membranes in reservoir-type intravaginal rings for on-demand drug delivery to prevent sexually transmitted infections (STIs). Close to zero drug release occurs at the normal vaginal pH (4.5) for minimal side effects. Drug release is only triggered by elevation of pH to 7 during heterosexual intercourse. The reversibly sharp and fast "on-and-off" switch arises from the creative incorporation of a pH-sensitive monomer in the soft segment of polyurethane. This polyurethane biomaterial holds great potential to better protect women who are generally at higher risk and are more vulnerable to STIs. PMID- 27717916 TI - Fabrication of novel ultradeformable bilosomes for enhanced ocular delivery of terconazole: In vitro characterization, ex vivo permeation and in vivo safety assessment. AB - The objective of this work was to encapsulate terconazole (TCZ), a water insoluble antifungal drug, into novel ultradeformable bilosomes (UBs) for achieving enhanced ocular delivery. In addition to the constituents of the conventional bilosomes; namely, Span 60, cholesterol, and the bile salts, UBs contain an edge activator which imparts extra elasticity to the vesicles and consequently hypothesized to result in improved corneal permeation. In this study, TCZ loaded UBs were prepared utilizing ethanol injection method according to 23 full factorial design. The investigation of the influence of different formulation variables on UBs properties and selection of the optimum formulation was done using Design-Expert(r) software. The selected UBs formulation (UB1; containing 10mg bile salt and 5mg Cremophor EL as an edge activator) showed nanosized spherical vesicles (273.15+/-2.90nm) and high entrapment efficiency percent (95.47+/-2.57%). Results also revealed that the optimum UBs formulation exhibited superior ex vivo drug flux through rabbit cornea when compared with conventional bilosomes, niosomes, and drug suspension. Furthermore, in vivo ocular tolerance and histopathological studies conducted using male albino rabbits proved the safety of the fabricated UBs after topical ocular application. Overall, the obtained results confirmed that UBs could be promising for ocular drug delivery. PMID- 27717915 TI - Changes in apoptosis-related gene expression and cytokine release in breast cancer cells treated with CpG-loaded magnetic PAMAM nanoparticles. AB - CpG-oligodeoxynucleotide (CpG-ODN) can function as an immune adjuvant. Previously, we showed that stimulation of breast cancer cells with CpG-ODN conjugated with PAMAM dendrimer-coated magnetic nanoparticles (DcMNPs) has induced apoptosis. The aim of the current study was to evaluate the expression levels of some apoptosis-regulating genes in several human breast cancer cells treated with CpG/DcMNPs. Treated MDA-MB231 cells showed an increase in Noxa and Bax gene expression levels, whereas the expression level of Survivin decreased. Similarly, Noxa gene was overexpressed in treated MCF7 cells. In treated SKBR3 cells, a decline in the c-Flip mRNA level was determined. Furthermore, release of cytokines, IL-6, IL-10, and TNF-alpha, was determined in cell culture supernatants. CpG/DcMNP treatment leads to an increase in the release of IL-6 in MDA-MB231 and SKBR3 cells, whereas release of IL-10 and TNF-alpha did not change significantly. It is indicated that CpG-ODN may show its cytotoxic effect by regulating the expression of apoptosis-related genes and the release of cytokine in breast cancer cells. PMID- 27717917 TI - Comparison of breaking tests for the characterization of the interfacial strength of bilayer tablets. AB - The bilayer tableting technology is gaining more acceptance in the drug industry, due to its ability to improve the drug delivery strategies. It is currently assessed by the European Pharmacopoeia, that the mechanical strength of tablets can be evaluated using a diametral breaking tester. This device applies a force diametrically, and records the tablet breaking point. This approach has been used to measure the structural integrity of single layer tablets as well as bilayer (and multi-layer) tablets. The latter ones, however, have a much complex structure. Therefore, testing a bilayer tablet with the currently used breaking test methodology might not be appropriate. The aim of this work was to compare results from several tests that have been proposed to quantify the interfacial strength of bilayer tablets. The obtained results would provide an indication on which tests are appropriate to evaluate the robustness of a bilayer tablet. Bilayer tablets were fabricated using a model formulation: Microcrystalline Cellulose (MCC) for the first layer, and spray dried lactose (SDLac) as second layer. Each set of tablets were tested using the following tests: Diametral Test, Shear Test and Indentation Test. The tablets were examined before and after the breaking test using Scanning Electron Microscopy (SEM). When a bilayer tablet was subjected to shearing or indentation, it showed signs of clear delamination. Differently, using the diametral test system, the tablets showed no clear difference, before and after the testing. However, when examining each layer via SEM, it was clear that a fracture occurred in the layer made of SDLac. Thus, the diametral test is a measure of the strength of one of the two layers and therefore it is not suited to test the mechanical strength of bilayer tablets. PMID- 27717918 TI - Evaluation of mesoporous carbon aerogels as carriers of the non-steroidal anti inflammatory drug ibuprofen. AB - Towards the development of novel drug carriers for oral delivery of poorly soluble drugs mesoporous aerogel carbons (CAs), namely CA10 and CA20 with different pore sizes (10 and 20nm, respectively), were evaluated. The non steroidal anti-inflammatory lipophilic compound ibuprofen was incorporated via passive loading. The drug loaded carbon aerogels were systemically investigated by means of High-Resolution Transmission Electron Microscopy (HR-TEM), Nitrogen physisorption studies, X-ray diffraction (XRD), Differential Scanning Calorimetry (DSC), X-ray photon electron spectroscopy (XPS) and zeta-potential studies. In vitro release studies were performed in simulated intestinal fluids reflecting both fasted (FaSSIF) and fed (FeSSIF) state conditions. Cytotoxicity studies were conducted with human intestinal cells (Caco-2). Drug was in an amorphous state in the pores of the carbon carrier as shown from the physicochemical characterization studies. The results showed marked differences in the release profiles for ibuprofen from the two aerogels in the media tested whereas in vitro toxicity profiles appear to be compatible with potential therapeutic applications at low concentrations.

PMID- 27717921 TI - Evaluation of a Digital Game-Based Learning Program for Enhancing Youth Mental Health: A Structural Equation Modeling of the Program Effectiveness. AB - BACKGROUND: Digital game-based learning (DGBL) makes use of the entertaining power of digital games for educational purposes. Effectiveness assessment of DGBL programs has been underexplored and no attempt has been made to simultaneously model both important components of DGBL: learning attainment (ie, educational purposes of DGBL) and engagement of users (ie, entertaining power of DGBL) in evaluating program effectiveness. OBJECTIVE: This study aimed to describe and evaluate an Internet-based DGBL program, Professor Gooley and the Flame of Mind, which promotes mental health to adolescents in a positive youth development approach. In particular, we investigated whether user engagement in the DGBL program could enhance their attainment on each of the learning constructs per DGBL module and subsequently enhance their mental health as measured by psychological well-being. METHODS: Users were assessed on their attainment on each learning construct, psychological well-being, and engagement in each of the modules. One structural equation model was constructed for each DGBL module to model the effect of users' engagement and attainment on the learning construct on their psychological well-being. RESULTS: Of the 498 secondary school students that registered and participated from the first module of the DGBL program, 192 completed all 8 modules of the program. Results from structural equation modeling suggested that a higher extent of engagement in the program activities facilitated users' attainment on the learning constructs on most of the modules and in turn enhanced their psychological well-being after controlling for users' initial psychological well-being and initial attainment on the constructs. CONCLUSIONS: This study provided evidence that Internet intervention for mental health, implemented with the technologies and digital innovations of DGBL, could enhance youth mental health. Structural equation modeling is a promising approach in evaluating the effectiveness of DGBL programs. PMID- 27717920 TI - The Effectiveness of Lower-Limb Wearable Technology for Improving Activity and Participation in Adult Stroke Survivors: A Systematic Review. AB - BACKGROUND: With advances in technology, the adoption of wearable devices has become a viable adjunct in poststroke rehabilitation. Regaining ambulation is a top priority for an increasing number of stroke survivors. However, despite an increase in research exploring these devices for lower limb rehabilitation, little is known of the effectiveness. OBJECTIVE: This review aims to assess the effectiveness of lower limb wearable technology for improving activity and participation in adult stroke survivors. METHODS: Randomized controlled trials (RCTs) of lower limb wearable technology for poststroke rehabilitation were included. Primary outcome measures were validated measures of activity and participation as defined by the International Classification of Functioning, Disability and Health. Databases searched were MEDLINE, Web of Science (Core collection), CINAHL, and the Cochrane Library. The Cochrane Risk of Bias Tool was used to assess the methodological quality of the RCTs. RESULTS: In the review, we included 11 RCTs with collectively 550 participants at baseline and 474 participants at final follow-up including control groups and participants post stroke. Participants' stroke type and severity varied. Only one study found significant between-group differences for systems functioning and activity. Across the included RCTs, the lowest number of participants was 12 and the highest was 151 with a mean of 49 participants. The lowest number of participants to drop out of an RCT was zero in two of the studies and 19 in one study. Significant between-group differences were found across three of the 11 included trials. Out of the activity and participation measures alone, P values ranged from P=.87 to P <=.001. CONCLUSIONS: This review has highlighted a number of reasons for insignificant findings in this area including low sample sizes, appropriateness of the RCT methodology for complex interventions, a lack of appropriate analysis of outcome data, and participant stroke severity. PMID- 27717922 TI - Interictal heart rate in patients with epilepsy. AB - INTRODUCTION: Electrocardiographic abnormalities in patients with epilepsy are related to the presence of discharges in central autonomic structures and the effect of antiepileptic drugs. These patients are at risk for sudden unexpected death, and cardiac arrhythmias are one of the most probable causes related to it. THE AIM: The heart rate (HR) assessment recorded on electrocardiography (ECG) in the interictal period in patients with newly diagnosed and previously treated epilepsy, depending on the type of changes in electroencephalography (EEG) and the treatment option. MATERIAL AND METHODS: Fifty patients with epilepsy were enrolled in the study: 22 comprised a non-treated patient (NTP) group with newly diagnosed epilepsy and 28 comprised a treated patient (TP) group that had been treated for more than 2 years. Resting ECG and EEG were performed in all patients. RESULTS: A significantly higher HR was recorded in the TP group compared to the NTP group (80+/-13 vs 67+/-15 bpm, p=0.00006). The tendency to higher HR was observed in polytherapy patients, carbamazepine patients and in patients with a focus in the right hemisphere. CONCLUSIONS: There is a relationship between the presence of the disorders related to bioelectric activities of the brain and the heart, therefore the ECG should be periodically monitored in epileptic patients. PMID- 27717923 TI - [Health behavior of polish physicians]. AB - INTRODUCTION: Physicians are perceived by patients as a competent source of information about health. However, the professional knowledge of health does not have to be identical with practicing health behavior in private life. THE AIM: To assess the health behaviors of Polish doctors. MATERIAL AND METHODS: We examined 614 medical practitioners. The mean age was 49.16+/-13.56 years. The average body mass index (BMI) was 24.81+/-4.09 kg /m2. The subjects completed medical studies on average 23.68+/-13.77 years ago. The majority (80.88%) had at least one medical specialization. The method was a diagnostic survey. Health Behavior Inventory (Inwentarz Zachowan Zdrowotnych or IZZ) was used and a special questionnaire containing questions about health behaviors not included in the IZZ. RESULTS: The dominance of unhealthy behaviors was observed in 27.34% of the group studied, the dominance of healthy behavior in 29.45% of participants. The others (43.21%) declared a similar extent of behavior in both categories. Participants were working an average of 40.42+/-18.77 hours a week, while they were sleeping an average of 6.56 +/- 1.03 hours a day. We observed the difference in the results of IZZ according to gender (p <0.01) and the partnership situation (p <0.01). It was also shown that there is a positive correlation between the result of IZZ and the time elapsed since the completion of specialization (p <0.01). Univariate analysis demonstrated a positive correlation between the fact of having a partner and a result of IZZ (p <0.01) and the difference between people showing healthy and unhealthy behaviors in terms of age (p<0.05) and the time elapsed since the completion of specialization (p<0.01). CONCLUSIONS: 1. Polish doctors are a diverse group in terms of health behavior. 2. Undertaking health behaviors by doctors is encouraged by: female sex, older age, lower BMI, a long time after completion of specialization. 3. Performing the medical profession is not the same as the manifestation of healthy behavior in private life. PMID- 27717924 TI - [Mechanisms of nitroxide-ergic dysregulation in tissues of parodontium in rats under combined excessive sodium nitrate and fluoride intake]. AB - INTRODUCTION: intake of inorganic nitrates is typically accompanied by production of excessive amount of nitric oxide (NO), which level is maintained by the mechanism of autoregulation known as the NO cycle. Hypothetically, this process may be disrupted with fluorides that are able to suppress arginase pathway of L arginine metabolism, which competes with NO-synthase pathway. AIM: to study mechanisms of disregulation of oxidative (NO-synthase) and non-oxidative (arginase) metabolic pathways of L-arginine in the tissues of periodontium under combined excessive sodium nitrate and fluoride intake. MATERIAL AND METHODS: these investigations were carried out on 90 white Wistar rats. Homogenates of parodontium soft tissues were used to assess spectrophotometrically the total activities of NO-synthase (NOS), arginase, ornithine decarboxylase as well as the peroxynitrite concentration. RESULTS: typical for the isolated sodium nitrate administration inhibition of total NOS activity varies under combined administration of nitrate and sodium fluoride and is usually manifested by its hyperactivation that is accompanied by an increase in peroxynitrite concentration. At this time arginase and ornithine decarboxylase activity is observed to be substantially reduced. The administration of aminoguanidine, an iNOS inhibitor, (20 mg/kg, twice a week during the experiment) increases arginase and ornithine decarboxylase activities, and the administration of L-arginine (500 mg/kg, twice a week) results in the increase of arginase activity. The administration of L-selenomethionine, a peroxynitrite scavenger (3 mg/kg, twice a week), and JSH-23 (4-methyl-N-(3-phenylpropyl) benzene-1,2-diamine, an inhibitor of NF-kappaB activation (1 mg/kg, twice a week) for modeling binary nitrate and fluoride intoxication reduces the total concentration of NOS activity and peroxynitrite concentration, and increases ornithine decarboxylase activity. CONCLUSIONS: the combined effect of nitrate and sodium fluoride for 30 days leads to disregulatory increased activity of NO-synthase enzymes and reduction of arginase pathway of L-arginine in the soft tissues of parodontium that is promoted by hyperactivation of iNOS and NF-kappaB, and increased peroxynitrite production.

AB - INTRODUCTION: electromyographic indices were developed for complex analysis of functional condition of orbicularis oris. AIM: to study electromyographic indices of orbicularis oris in patients with dental crowding in permanent occlusion. MATERIALS AND METHODS: thirty four patients with malocclusion and a severe degree of severity of dental crowding (15 males, 19 females, aged 16-29 years) who underwent orthodontic examination. The treatment group was divided into three: Group Ia comprised 11 subjects with mandibular crowding (mean age 19,27 +/- 1,08 years); group Ib, 10 patients with maxillary dental crowding (mean age 20,10 +/- 1,60 years) and group Ic, 13 subjects with both maxillary and mandibular crowding (mean age 20,15 +/- 1,45 years). The control group consisted of 10 patients with malocclusions but without dental crowding (mean age 20,70 +/- 1,32 years). The findings were compared with similar indices in subjects with normal occlusion (mean age 21,3 +/- 1,25 years). The index of orbicularis oris activity (ACTIV,%) was determined for each patient. A Student's t-test was used to analyze statistical difference between different groups. RESULTS: patients having crowding of maxillary teeth showed greater activity of muscles of the upper lip during maximum voluntary clenching (ACTIV= -0,99+/-7,44%). Activity of the muscles of the lower lip in patients with crowding of mandibular teeth (ASTIV=20,52+/-4,22%) and crowding of maxillary and mandibular teeth (ASTIV=17,93+/-4,33%) is prevailing. CONCLUSIONS: activity of the orbicularis oris in patients with malocclusion, complicated by dental crowding depend on clinical localization of crowding. PMID- 27717926 TI - [Ukrainian experience of health care for patients with diabetes]. AB - INTRODUCTION: diabetes mellitus is among the main challenges in the establishment of an effective health care system. A significant prevalence of disease and, consequently, a large number of complications, caused by it, provokes a constant searching for new measures and means for the struggle. In Ukraine, as in other countries, among methods of such a struggle is to standardize medical care. AIM: explore the state of health care for patients with diabetes in Ukraine. MATERIALS AND METHODS: to study the frequency of the measurement of certain quality indicators of patients with diabetes it was organized cross-sectional trial by the anonymous survey of 242 patients with a previously verified diagnosis of more than 2 years, at services of primary and secondary health care. RESULTS: obtained results are showed the presence of significant weaknesses in the providing of quality health care for patients with diabetes, in comparison with the requirements of national standards. Considering the features of detected flaws, they should be regarded as a result of an insufficient level of knowledge of their disease among patients and, possibly, the low average level of their income. CONCLUSIONS: the level of health care for patients of both types of diabetes does not meet recommended. Recommendations, which does not require personal expenses, are realized more efficiently, but not at the target level. Among the Ukrainian population level of implementation of the recommendations related to personal costs spending is at a critically low level, regardless of the type of disease. Solving of the identified problems could be achieved through the development of the network of primary health care services, closer to the patients, in conjunction with the organization and promotion of self-educational projects for patients and their physicians. PMID- 27717927 TI - Characteristics of the anthropometric measures and biological age of girls of Yakut ethnicity depending on tanner's index. AB - INTRODUCTION: severe climatic conditions of Yakutia influence the human morphofunctional status and it requires a comprehensive biomedical researches. The aim of this study was to examine the characteristics of the anthropometric measures and biological age of Yakut girls aged 16-20 depending on Tanner's index. MATERIALS AND METHODS: the analysis of anthropometric examination of 1276 girls is presented. Anthropometric measurements were performed using the method of V.V. Bunak (1941). The absolute values of the main components of the body were estimated according to Matiegka's formula (1921). The body mass index (BMI) was used. The type of body build was determined by Tanner's index (1968). Biological age was estimated by the coefficient of aging rate (A.G. Gorelkin, B.B. Pinkhasov, 2010). Obtained material was processed by the method of variation statistics with the use of SPSS (version 17.0). We used the methods of parametric and nonparametric statistics. RESULTS: the constitutional characteristics of girls have revealed the predominance of mesomorphic body type. Values of fat and bone body components had no significant difference depending on the body type by Tanner. Significant differences between the parameters of the pelvis and the amount of muscle body component were detected in the girls of gynemorphic and andromorphic body types. CONCLUSIONS: we revealed ethno-territorial differences among girls, which are characterized by the predominance in Yakut girls of the mesomorphic type of constitution by Tanner's index. The study of the indicators of biological age has elucidated constitutional differences.

AB - INTRODUCTION: endothelial dysfunction (ED) is one of the most important links in the pathogenesis of atherosclerosis (ASVD) - morphological basis of coronary artery disease (CAD). OBJECTIVE: to study the effect of polyphenolic antioxidants, resveratrol and quercetin, on endothelial degeneration factors in CAD patients. MATERIALS AND METHODS: the study involved 93 patients with coronary artery disease: stable angina pectoris, FC II. The cytofluorometric technique was applied to define the level of circulating endothelial microparticles (EMP) CD32+CD40+ in peripheral blood in order to identify ED. The content of tumor necrosis factor alpha (TNF-alpha), fibrinogen, hemocoagulation and lipid profile parameters were being determined in the blood, as well. Patients were divided into 3 groups. Basic therapy (beta-blockers, statins, aspirin) was prescribed to 33 persons of the comparison group, patients of the study group 1 (30 persons) additionally received resveratrol at a dose of 100 mg daily, patients of the study group 2 (30 persons) got quercetin at a dose of 3 g per day. In 2 months, the second examination of the patients was performed in the amount indicated. RESULTS: under the influence of resveratrol a significant reduction of the level of TNF-alpha and the number of EMP in peripheral blood was shown, in contrast to the results of other study groups. All groups showed a decrease in total cholesterol and low-density lipoprotein cholesterol, statistical differences between data of groups were not found. Indicators of coagulogramma in all study groups did not change significantly, however, there was a statistically significant reduction of fibrinogen in the blood. CONCLUSIONS: resveratrol, unlike quercetin, has a positive effect on the endothelial function and systemic inflammation, which may be the result of its influence on intracellular molecular cascades associated with the nuclear transcription factor of NF-kB. PMID- 27717929 TI - Ultrasonographic peculiarities of fetoplacental complex in pregnancy complicated by intrauterine infection. AB - INTRODUCTION: the relevance of intrauterine infections is determined by significant peri- and postnatal loss as well as health impairment, which often results in disability and reduced quality of life. Ultrasonography is employed in order to provide a reliable assessment of the functional state of the fetoplacental system secondary to intrauterine fetal infection in the course of pregnancy. Ultrasound imaging is essential in diagnosis of various preclinical complications of pregnancy and detection of abnormalities in the developing fetus. The aim of the study was to perform ultrasonographic assessment of fetoplacental complex in pregnancy complicated by intrauterine infection. MATERIALS AND METHODS: the study involved 304 pregnant women who underwent ultrasonographic and bacteriological somatogenic examination. The women were divided into the following groups depending on the presence and nature of the diagnosed infection: Group 1 - 50 patients with normal pregnancy, who were not found to have signs of infection (control group), Group 2 - 50 pregnant women with viral infections (CMV and herpes simplex virus); Group 3 - 50 pregnant women with bacterial infections (chlamydia, ureaplasma, mycoplasma), Group 4 - 154 patients with mixed viral and bacterial infections. Clinical groups with intrauterine infections (IUI) were considered main ones. RESULTS: increased echogenicity of the endothelium of internal and provisional organs was considered to be the main ultrasonographic sign of intrauterine fetal infections as these changes were equally observed in pregnant women of the main group. Main symptoms of viral infections included ventriculomegaly, hypoplasia of the chest, echogenic fibrous inclusions in the papillary muscles and valve flaps, hepatomegaly, placental hypoplasia, oligohydramnios. Dolichocephalic skull, choroid plexus cysts, gastromegaly, placental calcifications, polyhydramnios were more common in bacterial infections. Pregnant women with mixed viral and bacterial infections were found to have those and other signs of infection in equal measure. CONCLUSION: ultrasonographic somatogenic examination is of great diagnostic importance in preclinical diagnosis of intrauterine infection. Timely detection of changes in fetus and provisional organs provides a differentiated approach to administration of pathogenetically targeted treatment of this group of patients.

AB - INTRODUCTION: Research increasingly provide evidence that vegetarian diet can have a positive impact on health. The aim of this study was to analyze the fatty acid profile of vegetarian and non-vegetarian diet and prove which of them is more optimal in the context of some diet-related diseases prevention. MATERIAL AND METHODS: The study involved 83 women (47 vegetarians and 36 non-vegetarians). Estimates of the supply of individual fatty acids in the diet was based on analysis of 3-day dietary records (calculations in a computer program DIETA 5). RESULTS: Found: - in vegan diet significantly lower percentage of energy from SFA than in lactoovovegetarian diet and non-vegetarian diet (5,2% vs 11,2% i 11,9%), in vegan and lactoovovegetarian diet - significantly higher percentage of energy from PUFA than in non-vegetarian diet (9,2% i 7,8% vs 5,0%), - in vegan and lactoovovegetarian diet - significantly higher percentage of energy from LA than in non-vegetarian diet (6,7% i 5,5% vs 3,9%), - in vegan and lactoovovegetarian diet - significantly higher percentage of energy from ALA than in non-vegetarian diet (1,3% i 1,2% vs. 0,8%) - in vegan and lactoovovegetarian diet - significantly lower intake of EPA+DHA than in non-vegetarian diet (0 mg i 15 mg vs 76 mg), - only 25% of non-vegetarian diets fulfilled recommendations on the content of EPA + DHA Conclusions: Vegetarian, particularly vegan, nutrition may promote good balancing of the fatty acids in the diet, except for the long chain polyunsaturated omega-3, which are also deficient in the case of conventional diet. PMID- 27717931 TI - Problems and challenges in the early period of rehabilitating patients with severe hypothermia treated using ecmo support. AB - : The objectives: To show and discuss the most frequent functional problems encountered in patients who underwent extracorporeal membrane oxygenation (ECMO) treatment after severe hypothermia and point out appropriate physiotherapy procedures used in order to diminish the effects of hypothermia on the human organism. It is necessary to look for effective physiotherapeutic solutions, especially that the number of scientific publications on the subject is very limited. DESIGN: Retrospective analysis Setting: Severe Accidental Hypothermia Center ( medical intensive care unit of a university hospital) Patients or participants: Nineteen patients who were qualified for ECMO in Severe Accidental Hypothermia Center Intervention: At least three times a day rehabilitation session (physiotherapeutic procedures adequate to patient problems) and interventions in case of emergency. Physiotherapy staff in the Center has regular work hours and night duties, so can provide round-the clock rehabilitation treatment adjusted to the dynamically changing clinical picture of the patient. METHODS AND RESULTS: We analyzed the group of patients who were treated in our center from July 2013 to March 2015. The degree of functional complications increased with the duration and extent of hypothermia and time of conducting extracorporeal therapy. The frequent problems were: respiratory failure due to sputum retention (25%) or sternum fracture due to resuscitation (25%), lower and upper extremity muscle weakening (75%), peroneal nerve palsy (25%). In the first period of hospitalization all of patients have generalised edema. As a result of the treatment and rehabilitation, full stabilization of the cardiovascular - respiratory system and full recovery of neurological functions was achieved in 14 persons (73.68%). CONCLUSION: early and round-the clock physiotherapy treatment adequate to appearing patient's syndromes seems crucial for his physical and mental recovery after severe accidental hypothermia treated by ECMO support. In order to attain therapeutic success, it is indispensable to work in experienced, multidisciplinary team.

The results of subjective opinion of mood showed, that decrease the frequency tics disorders had in all children the direct shift on improvement their mood, and also satisfaction in their parents. CONCLUSIONS: The use of variable magnetic fields influenced on decrease the occurrence frequency tics disorders, and also on improvement quality of life the treated patients. PMID- 27717933 TI - Antiviral activity of the "Virus Blocking Factor" (VBF) derived i.a. from Pelargonium extract and Sambucus juice against different human-pathogenic cold viruses in vitro. AB - THE AIM: The in-vitro antiviral activity of the "Virus Blocking Factor" (VBF), a combination of Pelargonium extract and Sambucus juice with addition of Betaglucan 1,3 / 1,6, Zincum gluconium, Acidum ascorbicum, was studied against human pathogenic viruses: Influenza A H1N1 (FluA H1N1), Rhinovirus B subtype 14 (HRV14), Respiratory Syncytial Virus (RSV), Parainfluenzavirus subtype 3 (Para 3), and Adenovirus C subtype 5 (Adeno 5). METHOD: Antiviral activity was assessed using plaque-reduction assays after adding the test substance post infection of the MDCK, HeLa and HEp-2 cells with the viruses. Ribavirin Virazol and - in case of Adenovirus an internal laboratory standard - were used as positive controls. Cytotoxic effects of VBF and VBF Control onto the virus permissive MDCK, HeLa and HEp-2 cells were examined. Non-toxic concentrations of VBF were determined by the Methylthiazoletetrazolium test (MTT-Test). RESULTS AND CONCLUSIONS: In all antiviral studies VBF showed (2.1%) a dose-dependent antiviral activity against FluA H1N1 and HRV14 at non-toxic concentrations. A very strong effect was demonstrated in concentrations of 2.5% and 1.25% where replication of H1N1 and HRV14 was nearly completely blocked. Dose-dependent antiviral activity was detectable against RSV in a concentration range of 1.25% to 0.63% of the test item. Due to toxic side effects of a 2.5% concentration at least a "minor effect" of about 30% (1.25% solution) against Para 3 infected HEp-2 cells could be determined. Concerning Adeno 5 not any antiviral activity could be demonstrated in all studies with all tested substance concentrations of VBF. VBF Control did not show any cytotoxicity and antiviral effects. Further research is needed to elucidate clinical effect of VBF. PMID- 27717934 TI - [Definitions destruction of endothelial cells as a marker of endothelial dysfunction in aging men]. AB - INTRODUCTION: Ukraine occupies the 143 place in the world in life expectancy and the first place in terms of mortality. The main cause of death - cardiovascular diseases - 58%. Recent studies show the important and independent role of endothelium in the development of cardiovascular disease. THE AIM: examination of the endothelium destruction in aging men by determining the level of surface specific antigens of endothelial microparticles. MATERIALS AND METHODS: 88 men age from 45 to 76 years. 50 people of the main group had a history of the second type diabetes mellitus (DM-2) combined with arterial hypertension (AH). The control group included 38 men without aforementioned diseases. Also, men were divided into two groups by age: 45-59 years and over 60. RESULTS: in the main subgroup I endothelin level was higher than the control subgroup I: 2,07 +/- 0,6 and 1,27 +/- 0,25 (p <0.05). In main subgroup II endothelin level was also significantly higher compared with the specified index in control subgroup II: 3,91 +/- 0,7 and 1,79 +/- 0,27 (p <0.05). Among patients of the main subgroup II endothelin level (3,88 +/- 0,7 and 2,04 +/- 0,6 (p <0.05)), and triglycerides (2,77 +/- 0,08 vs. 1.99 +/- 0.05 (p <0.05)) was higher compared with the I subgroup. CONCLUSIONS: age androgen deficiency is accompanied by lipid metabolism, development of endothelial dysfunction, insulin resistance, diabetes and hypertension. Reduction of the cardiovascular risk includes measures aimed at normalizing hormonal balance and lipid metabolism in aging men with DM-2 and hypertension. PMID- 27717935 TI - Clinical examples of left ventricular non-compaction in adults. AB - INTRODUCTION: isolated left ventricular non-compaction (LVNC) is a heart disease with rather distinct morphologic and clinical manifestations. Available in the literature information about LVNC considering multiple left ventricle abnormal chords (LVAC) as one of its criterion motivated us to review the results obtained in the study of young patients with this pathology. The aim of the research was to demonstrate different clinical variants of left ventricular non-compaction course in adult patients and to clarify some pathogenetic aspects of this pathology. Materials and metods: comprehensive examination of 28 patients with multiple LVAC, 12 patients with LVNC and dilated idiopathic cardiomyopathy aged 16-36 was performed. RESULTS: according to the results of our research, 16 of 28 patients with multiple LVAC of left ventricle had ejection fraction more than 55%, in 6 patients this index range was 50-54%, in 6 it was 45-49%. Multiple LVAC were found to be associated with significantly greater clinical, phenotypic, structural and hemodynamic changes when compared both to control and solitary LVAC of any location (r<0.05). There were 12 young patients with multiple LVAC and ejection faction 22-41%. The detailed analysis of echocardiographic data in dynamics revealed other criteria of LVNC in all the patients. The data obtained suggest the relationship between pathogenetic mechanisms of heart pathology development in patients with connective tissue dysplasia syndrome and in patients with LVNS. Echocardiographic evidences of multiple LVAC designate the necessity of targeted search of left ventricular non-compacted signs and timely detection of left ventricular dilation. PMID- 27717936 TI - [Alteration mechanisms of oxidative stress at periodontal tissues of rats in a simulated periodontitis and elaborate methods of their correction]. AB - INTRODUCTION: one of the peroxidation stress mechanisms is inducible NO synthase (iNOS) expression involved in the pathogenesis of periodontitis. AIM: to access the influence of isoform NO synthase (NOS) on alteration mechanisms of oxidative stress at periodontal tissues of 50 mature rats in a simulated periodontitis (SP). MATERIALS AND METHODS: a SP at rats was induced by a high-carbohydrate, high-fat (HCHF) diet. Treated SP rat groups were intragastrically administered with selective neuronal NOS (nNOS) inhibitor 7-nitroindazole, selective inducible NOS (iNOS) inhibitor aminoguanidine, and nitric oxide synthase substrate L arginine. Oxidative stress level in the homogenated soft periodontal tissues was evaluated by TBARS (thiobarbituric acid reactive substances) level before and after 1,5 hours of incubation. Antioxidant response was evaluated by the increase in concentration of TBARS for incubation, and by antioxidant enzyme activity - superoxide dismutase and catalase. RESULTS: nNOS activity increase in a SP considerably limits oxidative stress activation at periodontal tissues, decreases antioxidant response, but heightens catalase activity. iNOS functional activity stimulates oxidative stress at periodontal tissues of rats, decreases antioxidant response. L-arginine in a MS effectively repaired antioxidant response at periodontal tissues that probably will give positive result at complex treatment of periodontitis and MS generally. CONCLUSIONS: in the near future, the appropriate regulation of NO activity by using NOS-active agents may provide a novel strategy for the periodontal disease prevention and correction in a MS. PMID- 27717937 TI - Peculiarities of heart rate in the patients with unstable angina and non-ST elevation myocardial infarction and concomitant diabetes mellitus type 2. AB - INTRODUCTION: type 2 diabetes mellitus is one of the most important medical and social problems in the world. Patients with diabetes are prone to coronary artery disease, in particular acute coronary syndrome, with atypical clinical signs and susceptibility to tachycardia. Elevated heart rate is an important factor of premature mortality in all patients with acute coronary syndrome. The aim of the investigation was to reveal the heart rate peculiarities in unstable angina and non-ST elevation myocardial infarction patients suffering from diabetes mellitus type 2 for more effective treatment of these patients. MATERIALS AND METHODS: 40 patients with unstable angina and non-ST elevation myocardial infarction were examined in the consecutive way during 2013- 2015 years. The patients were divided in two groups. The main group consisted of 25 patients with UA and NSTEMI with concomitant DM. The control group consisted of 15 patients with UA and NSTEMI but without DM. Basic clinical examinations, electrocardiography and 24 hours electrocardiography monitoring were performed. Carvedilol in the dose from 12.5 to 25 mg daily was also prescribed. RESULTS: we revealed statistically higher heart rate in the patients with unstable angina, non-ST elevation myocardial infarction and concomitant DM on hospitalization, at the fifth day of treatment and before their discharge from the hospital. CONCLUSIONS: 1. Patients with unstable angina and non-ST elevation myocardial infarction in associations with diabetes mellitus type 2 are characterized with increased heart rate partly resistant to beta-blockers, which indicates worse prognosis of cardiovascular diseases. 2. Prescription of carvedilol in daily dose 12.5 - 25 mg. is inadequate for obtaining HR < 70 bmp. in some patients with acute coronary syndrome and diabetes mellitus. 3. According to heart rate resistance to beta-blockers in patients with unstable angina and non-ST elevation myocardial infarction and concomitant diabetes mellitus patients need individual titration of higher doses of carvedilol.

AB - INTRODUCTION: nowadays, there are about 45 million blind individuals and, according to the prognosis, their quantity will reach over 76 million in 2020. In such a way, nowadays ophthalmological problems become more widespread, and the market of the ophthalmological services is not studied enough to understand all the tendencies and processes. AIM: was to study the patients' awareness on eye diseases and choice peculiarities of the information sources and medical institutions among various population age groups of Lutsk, Rivne and Ternopil cities. MATERIALS AND METHODS: the research was conducted as an anonymous questionnaire survey of respondents according to a specially designed integrated protocol by means of interviewing people at the streets of Lutsk (n=2000), Rivne (n=1500) and Ternopil (n=1500) cities. RESULTS: there was conducted a research on the population awareness concerning vision problems, analysis of social factors and peculiarities of the choice of information sources about eye diseases and factors influencing the choice of a medical institution and an ophthalmologist. It was determined that younger population prefers private medical institutions in almost half of the cases (95% confidence interval (CI) of the private institution choice probability: 0,48-0,52), while older population prefers mainly state ones (95% CI of the choice probability: 0,71-0,74). CONCLUSION: it was determined depending on the age, the range of people having vision problems varied from 22% in the "under 30 years" population group up to 76% in the "over 60 years" group, although at least 21,5% of the whole population realizing their problems do not address an ophthalmologist. PMID- 27717941 TI - The HELIO-geophysical storminess health effects in the cardio-vascular system of a human in the middle and high latitudes. AB - INTRODUCTION: cardiovascular impairment remains one of the most current problems of today's life and the definition of the connection between its development and the state of heliogeophysical storminess is currently important. The results of long-term researches of communication between cardiovascular catastrophes (myocardial infarction) and heliogeophysical storminess in the middle and high latitudes are shown in this work. AIM: to study the influence of space weather parameters on human cardio-vascular system in the high and middle latitudes. To define the particular space weather parameters and the mechanisms of their influence on human myocardial infarction progressing. MATERIAL AND METHODS: for the statistical processing of medical records data we use a spectral-time analysis, a correlation method and a method of overlapping of epochs. We have studied about 145 thousand medical records of ambulance medical services for the period of 1992 -2001. In order to define the reasons influencing the development of a myocardial infarction, we have made a comparison of myocardial infarction progress cases with Kp-index characterizing the level of geomagnetic storminess. RESULTS: the coincidence of geomagnetic storminess maximum with the cases of myocardial infarction, as well as the number of heart attacks excess in 1.5 times per a year near the maximum heliogeophysical activity (1992) compared to the year near the minimum of activity (1998) indicate possible influence of geomagnetic storminess on the myocardial infarction development of people living in subauroral latitudes. CONCLUSIONS: it was concluded that the appearance of heliogeophysical storminess in the myocardial infarction development in the mid latitudes is largely due to the presence of Pc1 geomagnetic pulsations, and in the high latitudes, especially in maximum years of heliogeophysical storminess, it is due to the geomagnetic storminess caused by the parameters of the solar wind and the interplanetary magnetic field. PMID- 27717942 TI - [Sarcopenia in rheumatoid arthritis]. AB - The clinical picture of rheumatoid arthritis covers the condition of chronic inflammation connected to the increased concentration of inflammatory mediators, reduced physical activity, immobilization caused by pain, stiffness and joint destruction as well as accompanying hormonal and metabolic disorders. It all may lead to extra-articular complications, also to the loss of muscle mass with the weakness of muscle strength, adding to the disability and significantly lowering the patients' quality of life. Sarcopenia is an advanced form of muscle mass loss which constitutes an independent and vital threat for dexterity. Attempts are made to define and classify sarcopenia basing on the measurements of muscle mass where the examinations are conducted by the method of computed tomography, magnetic resonance imaging, absorptiometry of two X-ray beams of various energies, electric bioimpedance and anthropometric methods. The data gained in few studies conducted in order to estimate the reduction of muscle mass in patients with rheumatoid arthritis confirm the significant increase of sarcopenia occurence in this group. Procedure with rheumatoid arthritis covers primarily treatment of the inflammatory process with traditional and biological medicaments that modify the course of illness. Such treatment seems to diminish the risk of equal sarcopenia occurrence. The effectiveness of using anabolic medicaments and high protein diet has not been proved. Currently, regular physical activity including aerobic exercise and exercises with load is considered a good method of muscle mass loss prevention and a procedure in case of confirmed muscle mass loss. PMID- 27717943 TI - Pediatric pain management - what are we able to do in Polish emergency medical services? AB - Pain management in emergency medical care remains underestimated, especially in pediatric patients. This is due to neglecting the issue, lack of knowledge in the appropriate use of analgesics and finally- the fear of being criticized by physicians in hospital departments. Moreover, it is difficult to objectively assess a child with acute pain. Even experienced "adult" anesthesiologists wonder how to recognize if a child suffers strong pain or is just anxious. Many different pain scales are available and some of them may be used in emergency medical care.. The administration of analgesia used in children depends on the patient's age and competencies of the providers of medical emergency teams.

AB - Arachnoid cysts are intracranial pathologies in the space between the pia mater and the dura mater of the brain and cerebellum. Arachnoid cysts are derived from the arachnoidea mater, which while yielding to germination or splitting creates a space filled with liquid with a composition similar to cerebrospinal fluid. The aim of the study is to present possible clinical symptoms and radiological presentation of intracranial arachnoid cysts. The symptoms of intracranial arachnoid cysts are dependent on its size and location. Small cysts are often asymptomatic, while reaching a large size they have the effect of weight, which can lead to oppression and displacement of neurovascular structures, increased intracranial pressure, and therefore such cysts may be the reason for the occurrence of neurological symptoms. Increasing headaches, dizziness, nausea with or without vomiting, stiff neck may even feign subarachnoid hemorrhage (SAH). In neuroimaging arachnoid cysts account for 1-2% of all intracranial pathologic masses. The most common location of arachnoid cysts is down the middle and rear of the skull in natural bodies of cerebrospinal fluid. Arachnoid cysts have a high rate of change. They can undergo spontaneous growth as well as the reduction or disappearance. Headaches, nausea or vomiting, worsening of mood, mental status changes, ataxia, seizures, hearing loss may be symptoms of serious intracranial pathology requiring diagnosis based on neuroimaging.

Currently, the World Health Organization warns that the rapid spread of the virus Zika in both Americas and an increase in the number of children born with microcephaly in these regions begins to be a serious epidemiological problem. Known ways of spreading this RNA virus of the Flaviviridae family is: with blood, sexual, vertical and even breast feeding. Currently used diagnostic tests are not entirely perfect, as they can detect infections by other viruses in this group but they are available in Poland. The treatment of clinical sings of ZIKV as unusual, flu-like symptoms is symptomatic. Unfortunately, the most dangerous consequences of infection tend to be: a statement of microcephaly in children of mothers bitten by the mosquitoes in the areas of epidemy of Zika and symptoms of Guillain-Barre syndrome. For this reason, doctors of all specialties should have current knowledge of the diagnosis, prevention, treatment and consequences of this infection.

Attention is paid to the importance of transplantation as a method of treatment and saving human lives. AIM: the clarify the feasibility of the introduction of donation commercialization as an avenue to solve the shortage of donor organs and means of combating with black organ market and finding alternative avenues solving these problems, which are more morally acceptable for society is the aim of this article. MATERIALS AND METHODS: the experience of foreign countries has been analyses in the research. Additionally, we used data from international organizations, conclusions scientists and report of Global Financial Integrity in the research. RESULTS: it is impossible to solve most problems by means of paid donation. CONCLUSIONS: therapeutic organ and tissue cloning based on genetic technology is the best way out and solving ethical transplantation problems.

It is responsible for transport and redistribution of lipids between cells and tissues. Apolipoprotein E circulates in blood mainly as a component of VLDL (very low density lipoproteins) HDL (high density lipoproteins) chylomicrons and chylomicron remnants. It assists in the flow of cholesterol from peripheral cells to extracellular space. Apolipoprotein E is one of the most studied apolipoproteins. There are three isoforms of this protein: E2, E3 and E4. Six polymorphic variants are defined by of the ApoE gene. Isoforms vary in their ability to bind to receptors for ApoE and LDL (low density lipoproteins) and affinity to lipoproteins. This is why we observe different metabolic responses in patients with various isoforms. The ApoE4 variant correlates with higher level of cholesterol in blood and thus with increased risk of atherosclerosis progression. Apolipoprotein E plays a key role in a wide range of actions. It is associated with lipids metabolism dysfunction which leads to cardiovascular diseases and also with neurodegenerative diseases of the central nervous system. In addition to classical methods of cardiac prevention, genetic tests should be performed more commonly. This could be useful in better evaluation of predisposition to pathological processes.

AB - The article discusses erectile dysfunction (ED) with the special emphasis on epidemiology, as well as the currently available medical treatments. Describing treatment methods authors paid special attention to natural therapies (as Panax ginseng, Tribulus terrestris, Vaccinium macrocarpon), because taking into consideration their safety profile, they appear to be an important alternative to therapies with synthetic molecules. From substances of natural origin, extract from the fruit of Tribulus terrestris ranks itself high on in collation at the end. The results of most clinical trials and experiments clearly demonstrate its effectiveness in improving sexual function in men.

AB - INTRODUCTION: the functioning of the healthcare industry in any country is impossible without providing enough medicines for patient care. This problem can best be resolved only when the majority of drugs, especially vital, will be made at national plants (industry). In this context, competition from generic drugs is the most optimal strategy to reduce drug's prices. AIM: the paper should examine how the legal regime of intellectual property affects the availability of medicines for people and identify ways of supporting breakthrough inventions and counter ?unreal innovations?. MATERIALS AND METHODS: for the purpose of study were generalized information from the scientific journals of medical and legal perspective, monographs by using a set of scientific methods. Namely under systematic approach have been analyzed the problems of pharmaceutical market, ways of producing generic and original drugs. Comparative legal method was useful for learning features of flexible mechanisms of the TRIPS Agreement and market regulation of medicines in the world. RESULTS: based on the research was found that developed countries with strong pharmaceutical industry are interested in maximizing the protection of intellectual property rights, including importing countries. Flexible mechanisms of the TRIPS Agreement can be useful for developing countries. CONCLUSIONS: thus, successful development of pharmaceutical industry and health care should be accompanied by the following measures: - improvement of public health must be recognized as a main task of government policy; - substantial state support aimed at increasing the availability of drugs in the domestic market and the strengthening of export potential; - decrease patent protection of medicines and stimulate market launch of generic copies. PMID- 27717950 TI - Eosinophilic cystitis and cholangitis - systemic disease triggered by mycobacterium tuberculosis? AB - Eosinophilic cystitis (EC) is a rare inflammatory disorder of the urinary tract characterized by infiltration of bladder with eosinophils. The cause remains unclear, immunological mechanisms have been implicated in pathogenesis. Potential etiological factors include: tumors, allergy, parasitic infections, trauma. The disease may have a variable course, from a mild self-limiting, through common symptoms like: dysuria, hematuria, abdominal pain, tumor, to severe renal failure, with eosinophilic infiltration of the other organs and systemic complications. Treatment depending on disease severity and etiology is pharmacological and/or surgical. Here we report a case of a previously healthy 16 year old girl with inflammatory tumor in the liver hilum infiltrating extrahepatic biliary tract who developed three months later haematuria with acute dysuric signs and renal failure. Based on histopathological findings diagnosis of eosinophilic cystitis was established. Tests for Mycobacterium tuberculosis were positive. To our knowledge, EC association with cholangitis and tuberculosis have never been reported before.

AB - The obstructive sleep apnea (OSA) is a mortality risk factor of the cardiovascular system diseases. One of the elements of this relationship is the occurrence of nocturnal cardiac arrhythmias. The arrhytmias in question are resistant to drug therapy so it is suggested to consider electrotherapy. However, the coexistence of OSA and thus recurrent episodes of nocturnal hypoxia, may have significant impact on the diagnosis and the treatment applied as shown in the following cases. In some cases, the decision of electrotherapy should be preceded by the use of therapy with continuous positive airway pressure (CPAP). PMID- 27717952 TI - Reversible complete atrioventricular block in patient with wegener's granulomatosis - a report on fortunate outcome with long term follow-up. AB - Reversible complete atrioventricular block in patient with Wegener's granulomatosis - a report on a positive outcome with long term follow-up. Atrioventricular (AV) block is a rare complication of Wegener's granulomatosis (WG), thus there are no standards of management in such cases. We present a case of a patient with a dual-chamber pacemaker (DDD) implanted due to complete AV block in the course of Wegener's granulomatosis (WG). An immunosuppressive therapy resulted in the resolution of non-cardiac and AV conduction disorders. The diagnostic functions of the pacemaker enabled us to evaluate AV conduction over a five-year follow-up period. The resolution of AV conduction disorders, which accompanied WG remission, suggests that careful monitoring with temporary cardiac pacing may be considered in some patients before permanent pacemaker implantation. PMID- 27717953 TI - The usefulness of free dicom viewers in rhinologic practice. AB - : Indroduction: The planning of the course of surgery in patients with paranasal sinus disorders requires the meticulous evaluation of computed tomography (CT) scans. However, ENT doctors still often receive unsatisfactory DICOM images, which require multiplanar reconstruction (MPR). THE AIM: The objective of the present study was to evaluate and test DICOM viewers with MPR function currently available on the Internet for free. MATERIAL AND METHODS: Detailed Internet searches and analysis of databases were carried out to find the maximum number of browsers. Available software was downloaded to assess, qualitatively and quantitatively, the parameters and functions useful in rhinologic practice. Additionally, a questionnaire was developed in order to ascertain the expectations and habits of ENT doctors in relation to DICOM browsers and CT scan evaluation. RESULTS AND CONCLUSIONS: Among the hundreds of browsers, 17 programs were chosen to be included in the final comparison. The outcomes of the survey proved that many free DICOM tools are effective alternatives to commercially available programs. However, the results do not enable us to predict precisely which tool will meet the needs of each physician. The survey among ENT doctors highlighted their limited awareness of software with MPR functions, in particular those that scored best in the test. PMID- 27717954 TI - Specific Features of Executive Dysfunction in Alzheimer-Type Mild Dementia Based on Computerized Cambridge Neuropsychological Test Automated Battery (CANTAB) Test Results. AB - BACKGROUND The primary manifestation of Alzheimer's disease (AD) is decline in memory. Dysexecutive symptoms have tremendous impact on functional activities and quality of life. Data regarding frontal-executive dysfunction in mild AD are controversial. The aim of this study was to assess the presence and specific features of executive dysfunction in mild AD based on Cambridge Neuropsychological Test Automated Battery (CANTAB) results. MATERIAL AND METHODS Fifty newly diagnosed, treatment-naive, mild, late-onset AD patients (MMSE >=20, AD group) and 25 control subjects (CG group) were recruited in this prospective, cross-sectional study. The CANTAB tests CRT, SOC, PAL, SWM were used for in-depth cognitive assessment. Comparisons were performed using the t test or Mann-Whitney U test, as appropriate. Correlations were evaluated by Pearson r or Spearman R. Statistical significance was set at p<0.05. RESULTS AD and CG groups did not differ according to age, education, gender, or depression. Few differences were found between groups in the SOC test for performance measures: Mean moves (minimum 3 moves): AD (Rank Sum=2227), CG (Rank Sum=623), p<0.001. However, all SOC test time measures differed significantly between groups: SOC Mean subsequent thinking time (4 moves): AD (Rank Sum=2406), CG (Rank Sum=444), p<0.001. Correlations were weak between executive function (SOC) and episodic/working memory (PAL, SWM) (R=0.01-0.38) or attention/psychomotor speed (CRT) (R=0.02 0.37). CONCLUSIONS Frontal-executive functions are impaired in mild AD patients. Executive dysfunction is highly prominent in time measures, but minimal in performance measures. Executive disorders do not correlate with a decline in episodic and working memory or psychomotor speed in mild AD. PMID- 27717956 TI - Natural variations in stearoyl-acp desaturase genes affect the conversion of stearic to oleic acid in maize kernel. AB - KEY MESSAGE: We identified 11 SAD genes, and mined their natural variations associated with the conservation of stearic to oleic acid, especially ZmSAD1 supported by both the QTL and an expression QTL. Maize oil is generally regarded as a healthy vegetable oil owing to its low abundance of saturated fatty acids. Stearoyl-ACP desaturase (SAD) is a key rate-limiting enzyme for the conservation of stearic (C18:0) to oleic (C18:1) acid. Here, 11 maize SAD genes were identified to have more divergent functions than Arabidopsis SAD genes. The genomic regional associations in a maize panel including 508 inbred lines identified 6 SAD genes significantly associated (P < 0.01) with the C18:0/C18:1 ratio or the level of C18:0 or C18:1, one gene of which co-localized with a quantitative trait locus (QTL) and 5 of which co-localized with an expression QTL. ZmSAD1, supported by both the QTL and an expression QTL, had the largest effect on C18:0/C18:1. One nonsynonymous single-nucleotide polymorphism in exon 3 and one 5-bp insertion/deletion in the 3' untranslated region were further shown to contribute to the natural variation in C18:0/C18:1 according to ZmSAD1-based association mapping. Finally, selection tests of ZmSAD1 in teosinte, regular maize, and high-oil maize indicated that ZmSAD1 was not a selection target during the process of maize domestication and high-oil maize development. These results will guide the manipulation of the ratio between saturated and unsaturated fatty acids in maize. PMID- 27717955 TI - From Mendel's discovery on pea to today's plant genetics and breeding : Commemorating the 150th anniversary of the reading of Mendel's discovery. AB - KEY MESSAGE: This work discusses several selected topics of plant genetics and breeding in relation to the 150th anniversary of the seminal work of Gregor Johann Mendel. In 2015, we celebrated the 150th anniversary of the presentation of the seminal work of Gregor Johann Mendel. While Darwin's theory of evolution was based on differential survival and differential reproductive success, Mendel's theory of heredity relies on equality and stability throughout all stages of the life cycle. Darwin's concepts were continuous variation and "soft" heredity; Mendel espoused discontinuous variation and "hard" heredity. Thus, the combination of Mendelian genetics with Darwin's theory of natural selection was the process that resulted in the modern synthesis of evolutionary biology. Although biology, genetics, and genomics have been revolutionized in recent years, modern genetics will forever rely on simple principles founded on pea breeding using seven single gene characters. Purposeful use of mutants to study gene function is one of the essential tools of modern genetics. Today, over 100 plant species genomes have been sequenced. Mapping populations and their use in segregation of molecular markers and marker-trait association to map and isolate genes, were developed on the basis of Mendel's work. Genome-wide or genomic selection is a recent approach for the development of improved breeding lines. The analysis of complex traits has been enhanced by high-throughput phenotyping and developments in statistical and modeling methods for the analysis of phenotypic data. Introgression of novel alleles from landraces and wild relatives widens genetic diversity and improves traits; transgenic methodologies allow for the introduction of novel genes from diverse sources, and gene editing approaches offer possibilities to manipulate gene in a precise manner. PMID- 27717957 TI - Early post-surgical cognitive dysfunction is a risk factor for mortality among hip fracture hospitalized older persons. AB - : This study investigates the relationship between cognitive dysfunction or delirium detected in the early post-surgical phase and the 1-year mortality among 514 hip fracture hospitalized older persons. Patients with early cognitive dysfunction or delirium experienced a 2-fold increased mortality risk. Early post operative cognitive dysfunction and delirium are negative prognostic factors for mortality. BACKGROUND AND PURPOSE: Premorbid cognitive impairment and dementia in older individuals negatively affect functional recovery after hip fracture. Additionally, post-operative delirium is an established risk factor for negative outcomes among hip fracture patients. While the majority of hip fracture patients experience minor post-surgical cognitive dysfunction, the prognostic value of this phenomenon is unknown. Therefore, we investigated the relationship between minor cognitive dysfunction or delirium detected in the early post-surgical phase and the 1-year mortality after index hip fracture. SUBJECTS AND METHODS: We enrolled 514 patients with hip fracture (77.4 % women), aged 65 years or older (mean age 83.1 +/- 7.3 years), who underwent surgical hip fracture repair. Patients were assessed daily from the second to the fourth post-operative day and at 3, 6, and 12 months thereafter. All participants underwent comprehensive assessment, including detection of delirium by using the confusion assessment method and evaluation of cognitive function by using mini-mental state examination (MMSE; score range 0 to 30, with lower scores indicating poorer performance). In the absence of delirium, post-surgical cognitive dysfunction was defined as having low performance on MMSE. Vital status of 1 year after the index fracture and date of death were gathered from local registries. RESULTS: The observed 1-year mortality rate was 14.8 %. Men were more likely to die than women within 1 year of the index fracture (p < 0.01). Compared to participants with better cognitive performance, those with MMSE < 24, as well as those with delirium in the post-operative phase, showed a significantly higher 1-year mortality rate (23.3 versus 17.9 and 8.1 %, respectively). Independent of age and sex, post-operative cognitive dysfunction as well as delirium was both associated with a 2-fold increased mortality risk. CONCLUSIONS: The presence of minor cognitive dysfunction in the early post-surgical phase is a negative prognostic factor for mortality among elderly hip fracture patients. The burden of minor cognitive dysfunction is likely superimposed on that of delirium in subgroups of frail patients. PMID- 27717959 TI - Endotrophin, a multifaceted player in metabolic dysregulation and cancer progression, is a predictive biomarker for the response to PPARgamma agonist treatment. AB - Endotrophin is a cleavage product derived from the collagen VI(alpha3) chain. Collagen VI is expressed in a number of different tissues, but adipose tissue is a particularly prominent source for this extracellular matrix constituent. Mice lacking collagen VI are metabolically healthier due to reduced fibrosis in adipose tissue. Endotrophin seems to be one of the key players of collagen VI mediated signalling effects, including its pro-fibrotic nature and chemoattractant properties for macrophages, while also playing an important role in cancer progression and the chemoresistance of tumour cells. The glucose lowering class of thiazolidinediones (TZDs) that mediate their action through the nuclear receptor peroxisome proliferator-activated receptor (PPAR)gamma also exerts important effects on endotrophin by reducing the transcription of parental collagen VI molecules. As with many other pharmacological interventions, there is a range of responses observed in a diabetic patient population. In this issue of Diabetologia, Karsdal and colleagues (DOI: 10.1007/s00125-016-4094-1 ) demonstrate that baseline endotrophin levels offer excellent predictive values to indicate individuals who will show an optimised response to TZDs with respect to the lowering of HbA1c and reduced risk of adverse side effects. The identification of a predictive biomarker for optimal responders is an important step in highlighting the continued viability of TZDs as an effective glucose lowering class of compounds. PMID- 27717960 TI - Dementia onset, incidence and risk in type 2 diabetes: a matched cohort study with the Fremantle Diabetes Study Phase I. AB - AIMS/HYPOTHESIS: The study aimed to assess the incidence, age of onset, survival and relative hazard of dementia in well-categorised community-based patients with type 2 diabetes compared with a matched cohort of individuals without diabetes. METHODS: A longitudinal observational study was undertaken involving 1291 participants with type 2 diabetes from the Fremantle Diabetes Study and 5159 matched residents without documented diabetes. Linkage with health-related databases was used to detect incident dementia. Relative hazards were assessed using both cause-specific and subdistribution proportional hazards models. RESULTS: During 13.8 +/- 5.8 years of follow-up, incident dementia occurred in 13.9% and 12.4% of the groups of participants with and without diabetes, respectively (p = 0.15). With type 2 diabetes, the incidence of dementia was higher (incidence rate ratio [IRR] 1.28, 95% CI 1.08, 1.51), as was the competing risk of death (IRR 1.50, 95% CI 1.38, 1.64). The ages when dementia was first recorded and when death with dementia occurred were both earlier with diabetes, by 1.7 (95% CI 0.6, 2.9) and 2.3 (95% CI 1.1, 3.6) years, respectively (both p <= 0.004). Type 2 diabetes was associated with an adjusted subdistribution HR of 1.18 (95% CI 1.00, 1.39), and a cause-specific HR of 1.51 (95% CI 1.27, 1.78) for all-cause dementia. CONCLUSIONS/INTERPRETATION: Type 2 diabetes is associated with an increased incidence of dementia, and dementia onset occurs at a younger age. The relative hazards of both dementia and premature mortality are increased and, as a consequence, the increased risk of dementia in type 2 diabetes is not as marked as suggested by cause-specific HRs. PMID- 27717958 TI - Molecular modelling and molecular dynamics of CFTR. AB - The cystic fibrosis transmembrane conductance regulator (CFTR) protein is a member of the ATP-binding cassette (ABC) transporter superfamily that functions as an ATP-gated channel. Considerable progress has been made over the last years in the understanding of the molecular basis of the CFTR functions, as well as dysfunctions causing the common genetic disease cystic fibrosis (CF). This review provides a global overview of the theoretical studies that have been performed so far, especially molecular modelling and molecular dynamics (MD) simulations. A special emphasis is placed on the CFTR-specific evolution of an ABC transporter framework towards a channel function, as well as on the understanding of the effects of disease-causing mutations and their specific modulation. This in silico work should help structure-based drug discovery and design, with a view to develop CFTR-specific pharmacotherapeutic approaches for the treatment of CF in the context of precision medicine.

PMID- 27717963 TI - A unique intracellular compartment formed during the oligotrophic growth of Rhodococcus erythropolis N9T-4. AB - Rhodococcus erythropolis N9T-4, isolated from stored crude oil, shows extremely oligotrophic features and can grow on a basal medium without any additional carbon, nitrogen, sulfur, and energy sources, but requires CO2 for its oligotrophic growth. Transmission electron microscopic observation showed that a relatively large and spherical compartment was observed in a N9T-4 cell grown under oligotrophic conditions. In most cases, only one compartment was observed per cell, but in some cases, it was localized at each pole of the cell, suggesting that it divides at cell division. We termed this unique bacterial compartment an oligobody. The oligobody was not observed or very rarely observed in small sizes under nutrient rich conditions, whereas additional carbon sources did not affect oligobody formation. Energy dispersive X-ray spectroscopy analysis revealed remarkable peaks corresponding to phosphorus and potassium in the oligobody. The oligobodies in N9T-4 cells could be stained by Toluidine blue, suggesting that the oligobody is composed of inorganic polyphosphate and is a type of acidocalcisome. Two genes-encoding polyphosphate kinases, ppk1 and ppk2, were found in the N9T-4 genome: ppk1 disruption caused a negative effect on the formation of the oligobody. Although it was suggested that the oligobody plays an important role for the oligotrophic growth, both ppk-deleted mutants showed the same level of oligotrophic growth as the wild-type strain. PMID- 27717964 TI - Incubation of innovative methanogenic communities to seed anaerobic digesters. AB - The methanogenic communities in alternative inocula and their potential to increase CH4 production in mesophilic and psychrophilic dairy manure-based anaerobic digesters were examined. Quantitative-PCR and terminal restriction fragment length polymorphism (T-RFLP) profiles were used to determine archaeal and methanogenic community changes when three inocula (wetland sediment (WS), landfill leachate (LL), and mesophilic digestate (MD)) were incubated at 15, 25, and 35 degrees C for 91 and 196 days. After each incubation period, the inocula were used in biochemical methane potential (BMP) tests at the incubation temperatures. There was no significant correlation between inoculum mcrA gene copy numbers and CH4 produced in BMP tests, suggesting that population size was not a distinguishing characteristic for predicting CH4 production. Archaeal composition in LL and WS reactors generally converged with MD reactors after incubation at 25 and 35 degrees C for 196 days. These MD reactors had high relative abundance of TRF 302, likely Methanosaetaceae, and low acetic acid (0.62 1.61 mM). At 15 degrees C incubation, most reactors were associated with high acetic acid (1.61-133.6 mM) and dominated by TRF 199, likely Methanosarcinaceae. The LL reactor incubated at 25 degrees C for 91 days had higher relative abundance of TRF 199 and produced significantly higher CH4 than WS and MD reactors in BMP test. In the future, it may be possible to create enrichment cultures that favor particular methanogens and use them as inoculum to benefit digesters at low mesophilic temperatures. Our data provides evidence that tailoring the archaeal community could benefit digesters operating under different conditions. PMID- 27717965 TI - Biosynthesis of nanoparticles of metals and metalloids by basidiomycetes. Preparation of gold nanoparticles by using purified fungal phenol oxidases. AB - The work shows the ability of cultured Basidiomycetes of different taxonomic groups-Lentinus edodes, Pleurotus ostreatus, Ganoderma lucidum, and Grifola frondosa-to recover gold, silver, selenium, and silicon, to elemental state with nanoparticles formation. It examines the effect of these metal and metalloid compounds on the parameters of growth and accumulation of biomass; the optimal cultivation conditions and concentrations of the studied ion-containing compounds for recovery of nanoparticles have been identified. Using the techniques of transmission electron microscopy, dynamic light scattering, X-ray fluorescence and X-ray phase analysis, the degrees of oxidation of the bioreduced elements, the zeta-potential of colloidal solutions uniformity, size, shape, and location of the nanoparticles in the culture fluid, as well as on the surface and the inside of filamentous hyphae have been determined. The study has found the part played by homogeneous chromatographically pure fungal phenol-oxidizing enzymes (laccases, tyrosinases, and Mn-peroxidases) in the recovery mechanism with formation of electrostatically stabilized colloidal solutions. A hypothetical mechanism of gold(III) reduction from HAuCl4 to gold(0) by phenol oxidases with gold nanoparticles formation of different shapes and sizes has been introduced. PMID- 27717966 TI - The role of sponge-bacteria interactions: the sponge Aplysilla rosea challenged by its associated bacterium Streptomyces ACT-52A in a controlled aquarium system. AB - Sponge-associated bacteria play a critical role in sponge biology, metabolism and ecology, but how they interact with their host sponges and the role of these interactions are poorly understood. This study investigated the role of the interaction between the sponge Aplysilla rosea and its associated actinobacterium, Streptomyces ACT-52A, in modifying sponge microbial diversity, metabolite profile and bioactivity. A recently developed experimental approach that exposes sponges to bacteria of interest in a controlled aquarium system was improved by including the capture and analysis of secreted metabolites by the addition of an absorbent resin in the seawater. In a series of controlled aquaria, A. rosea was exposed to Streptomyces ACT-52A at 106 cfu/ml and monitored for up to 360 h. Shifts in microbial communities associated with the sponges occurred within 24 to 48 h after bacterial exposure and continued until 360 h, as revealed by TRFLP. The metabolite profiles of sponge tissues also changed substantially as the microbial community shifted. Control sponges (without added bacteria) and Streptomyces ACT-52A-exposed sponges released different metabolites into the seawater that was captured by the resin. The antibacterial activity of compounds collected from the seawater increased at 96 and 360 h of exposure for the treated sponges compared to the control group due to new compounds being produced and released. Increased antibacterial activity of metabolites from treated sponge tissue was observed only at 360 h, whereas that of control sponge tissue remained unchanged. The results demonstrate that the interaction between sponges and their associated bacteria plays an important role in regulating secondary metabolite production. PMID- 27717961 TI - Malignant inflammation in cutaneous T-cell lymphoma-a hostile takeover. AB - Cutaneous T-cell lymphomas (CTCL) are characterized by the presence of chronically inflamed skin lesions containing malignant T cells. Early disease presents as limited skin patches or plaques and exhibits an indolent behavior. For many patients, the disease never progresses beyond this stage, but in approximately one third of patients, the disease becomes progressive, and the skin lesions start to expand and evolve. Eventually, overt tumors develop and the malignant T cells may disseminate to the blood, lymph nodes, bone marrow, and visceral organs, often with a fatal outcome. The transition from early indolent to progressive and advanced disease is accompanied by a significant shift in the nature of the tumor-associated inflammation. This shift does not appear to be an epiphenomenon but rather a critical step in disease progression. Emerging evidence supports that the malignant T cells take control of the inflammatory environment, suppressing cellular immunity and anti-tumor responses while promoting a chronic inflammatory milieu that fuels their own expansion. Here, we review the inflammatory changes associated with disease progression in CTCL and point to their wider relevance in other cancer contexts. We further define the term "malignant inflammation" as a pro-tumorigenic inflammatory environment orchestrated by the tumor cells and discuss some of the mechanisms driving the development of malignant inflammation in CTCL. PMID- 27717967 TI - A new assay for the simultaneous identification and differentiation of Klebsiella oxytoca strains. AB - Klebsiella oxytoca is the second most frequently identified species of Klebsiella isolated from hospitalized patients. Klebsiella spp. is difficult to identify using conventional methods and is often misclassified in clinical microbiology laboratories. K. oxytoca is responsible for an increasing number of multi resistant infections in hospitals because of insufficient detection and identification. In this study, we propose a new simple method called pehX-LM PCR/XbaI, which simultaneously indicates K. oxytoca species and genotype by the fingerprint pattern. The pehX-LM PCR/XbaI is a combination of the following two methods: species-specific amplification of pehX gene and non-specific amplification of short restriction fragments by the LM PCR method. The specificity and the discrimination power of the pehX-LM PCR/XbaI method were determined by typing 209 K. oxytoca strains (included 9 reference strains), 28 K. pneumoniae, and other 25 strains belonging to the Enterobacteriaceae. The typing results were confirmed by the PCR melting profile method. Unlike the known fingerprinting methods, the pehX-LM PCR/XbaI leads to a clear pattern (approx. 3 5 bands) with a sufficient, relatively high discriminatory power. As a result, the time and cost of a single analysis are lower. The method can be used both in clinical and environmental research. PMID- 27717968 TI - Beneficial microorganisms for honey bees: problems and progresses. AB - Nowadays, honey bees are stressed by a number of biotic and abiotic factors which may compromise to some extent the pollination service and the hive productivity. The EU ban of antibiotics as therapeutic agents against bee pathogens has stimulated the search for natural alternatives. The increasing knowledge on the composition and functions of the bee gut microbiota and the link between a balanced gut microbiota and health status have encouraged the research on the use of gut microorganisms to improve bee health. Somehow, we are assisting to the transfer of the "probiotic concept" into the bee science. In this review, we examine the role of the honey bee gut microbiota in bee health and critically describe the available applications of beneficial microorganisms as pest control agents and health support. Most of the strains, mainly belonging to the genera Lactobacillus, Bifidobacterium and Bacillus, are isolated from honey bee crop or gut, but some applications involve environmental strains or formulation for animal and human consumption. Overall, the obtained results show the favourable effect of applied microbial strains on bee health and productivity, in particular if strains of bee origin are used. However, it is actually not yet possible to conclude whether this strategy will ever work. In particular, many aspects regarding the overall setup of the experiments, the dose, the timing and the duration of the treatment need to be optimized, also considering the microbiological safety of the hive products (i.e. pollen and honey). In addition, a deep investigation about the effect on host immunity and physiology is envisaged. Lastly, the final users of the formulations, i.e. beekeepers, should be taken into account for the achievement of high-quality, cost-effective and easy-to-use products. PMID- 27717969 TI - Multiple origins of gigantism in stem baleen whales. AB - Living baleen whales (Mysticeti) include the world's largest animals to have ever lived-blue whales (Balaenoptera musculus) can reach more than 30 m. However, the gigantism in baleen whales remains little explored. Here, we compiled all published stem mysticetes from the Eocene and Oligocene and then mapped the estimated body size onto different phylogenies that suggest distinct evolutionary histories of baleen whales. By assembling all known stem baleen whales, we present three novel findings in early mysticete evolution. Results show that, regardless of different phylogenetic scenarios, large body size (more than 5-m long) evolved multiple times independently in their early evolutionary history. For example, the earliest known aetiocetid (Fucaia buelli, 33-31 Ma) was small in size, about 2 m, and a later aetiocetid (Morawanocetus-like animal, 26-23 Ma) can reach 8-m long-almost four times the size of Fucaia buelli-suggesting an independent gigantism in the aetiocetid lineage. In addition, our reconstruction of ancestral state demonstrates that the baleen whales originated from small body size (less than 5 m) rather than large body size as previously acknowledged. Moreover, reconstructing the evolution of body size in stem baleen whales suggests that the initial pulse of mysticete gigantism started at least back to the Paleogene and in turn should help to understand the origin, pattern, and process of the extreme gigantism in the crown baleen whales. This study illustrates that Cope's rule is insufficient to explain the evolution of body size in a group that comprises the largest animals in the history of life, although currently the lack of exact ancestor-descendant relationships remains to fully reveal the evolutionary history of body size.

PMID- 27717970 TI - Maintenance of drug metabolism and transport functions in human precision-cut liver slices during prolonged incubation for 5 days. AB - Human precision-cut liver slices (hPCLS) are a valuable ex vivo model that can be used in acute toxicity studies. However, a rapid decline in metabolic enzyme activity limits their use in studies that require a prolonged xenobiotic exposure. The aim of the study was to extend the viability and function of hPCLS to 5 days of incubation. hPCLS were incubated in two media developed for long term culture of hepatocytes, RegeneMed(r), and Cellartis(r), and in the standard medium WME. Maintenance of phase I and II metabolism was studied both on gene expression as well as functional level using a mixture of CYP isoform-specific substrates. Albumin synthesis, morphological integrity, and glycogen storage was assessed, and gene expression was studied by transcriptomic analysis using microarrays with a focus on genes involved in drug metabolism, transport and toxicity. The data show that hPCLS retain their viability and functionality during 5 days of incubation in Cellartis(r) medium. Albumin synthesis as well as the activity and gene expression of phase I and II metabolic enzymes did not decline during 120-h incubation in Cellartis(r) medium, with CYP2C9 activity as the only exception. Glycogen storage and morphological integrity were maintained. Moreover, gene expression changes in hPCLS during incubation were limited and mostly related to cytoskeleton remodeling, fibrosis, and moderate oxidative stress. The expression of genes involved in drug transport, which is an important factor in determining the intracellular xenobiotic exposure, was also unchanged. Therefore, we conclude that hPCLS cultured in Cellartis(r) medium are a valuable human ex vivo model for toxicological and pharmacological studies that require prolonged xenobiotic exposure. PMID- 27717973 TI - [The scaphoid and rheumatoid arthritis : Classification by retrospective X-ray analysis]. AB - BACKGROUND: Early destruction of the wrist in rheumatoid arthritis is common and often progressive. Even in times of improved and standardized medical treatment this cannot always be prevented. OBJECTIVES: A limited range of motion, pain, reduced grip-force, and aesthetic deficits of the wrist can impair the daily life of patients. There is an additional risk for destruction of the surrounding soft tissue and adjoining joints of the upper extremity. RESULTS: Destruction of wrist in rheumatoid arthritis is multifactorial and is localized in many different structures of the wrist. In this context, scaphoid and periscaphoid structures are of interest. Data were gathered in a retrospective study of the wrist X-rays of patients with rheumatoid arthritis. The possible consequences for operative options are described. PMID- 27717974 TI - Response to letter to the editor. PMID- 27717972 TI - Assessment of demographic and pathoanatomic risk factors in recurrent patellofemoral instability. AB - PURPOSE: The WARPS/STAID classification employs clinical assessment of presenting features and anatomic characteristics to identify two distinct subsets of patients within the patellofemoral instability population. The purpose of this study was to further define the specific demographics and the prevalence of risky pathoanatomies in patients classified as either WARPS or STAID presenting with recurrent patellofemoral instability. A secondary purpose was to further validate the WARPS/STAID classification with the Banff Patella Instability Instrument (BPII), the Marx activity scale and the Patellar Instability Severity Score (ISS). METHODS: A convenience sample of 50 patients with recurrent patellofemoral instability, including 25 WARPS and 25 STAID subtype patients, were assessed. Clinical data were collected including assessment of demographic risk factors (sex, BMI, bilaterality of symptoms, affected limb side and age at first dislocation) and pathoanatomic risk factors (TT-TG distance, patella height, patellar tilt, grade of trochlear dysplasia, Beighton score and rotational abnormalities of the tibia or femur). Patients completed the BPII and the Marx activity scale. The ISS was calculated from the clinical assessment data. Patients were stratified into the WARPS or STAID subtypes for comparative analysis. An independent t test was used to compare demographics, the pathoanatomic risk factors and subjective measures between the groups. Convergent validity was tested with a Pearson r correlation coefficient between the WARPS/STAID and ISS scores. RESULTS: Demographic risk factors statistically associated with a WARPS subtype included female sex, age at first dislocation and bilaterality. Pathoanatomic risk factors statistically associated with a WARPS subtype included trochlear dysplasia, TT-TG distance, generalized ligamentous laxity, patellar tilt and rotational abnormalities. The independent t test revealed a significant difference between the ISS scores: WARPS subtype (M = 4.4, SD = 1.1) and STAID subtype (M = 2.5, SD = 1.5); t(48) = 5.2, p < 0.001. The relationship between the WARPS/STAID and the ISS scores, measured using a Pearson r correlation coefficient, demonstrated a strong relationship: r = -0.61, n = 50, p < 0.001. CONCLUSIONS: This study has demonstrated statistically significant evidence that certain demographics and pathoanatomies are more prevalent in each of the WARPS and STAID patellofemoral instability subtypes. There was no difference in quality-of-life or activity level between the subtypes. The WARPS/STAID score demonstrated convergent validity to the ISS and divergent validity to the BPII score and the Marx activity scale. This study has further validated both the WARPS/STAID classification and the ISS of patients that present with recurrent patellofemoral instability. LEVEL OF EVIDENCE: III. PMID- 27717975 TI - Diagnostic accuracy of 3T conventional shoulder MRI in the detection of the long head of the biceps tendon tears associated with rotator cuff tendon tears. AB - OBJECTIVE: To evaluate the diagnostic performance (DP) of 3T (3 Tesla field strength) conventional shoulder magnetic resonance imaging (MRI) in detecting the long head of the biceps tendon (LHBT) tears in association with rotator cuff tendon tears. MATERIALS AND METHODS: This study included 80 consecutive patients who underwent arthroscopic surgery for rotator cuff tendon tears. Two radiologists independently evaluated the preoperative 3T shoulder MRI for the presence of LHBT tears. The DP of MRI was evaluated using the results of arthroscopy as the reference standard. We also evaluated the DP of several MR signs of LHBT in detection of partial LHBT tears. RESULTS: Arthroscopic examination revealed 35 partial and 5 complete tears. According to the results of evaluation by reviewers 1 and 2, shoulder MRI exhibited sensitivities of 77.14 and 80 % and specificities of 71.11 and 73.33 % in detection of partial LHBT tears and sensitivities of 80 and 100 % and a specificity of 100% (both) in detection of complete LHBT tears. In detecting partial LHBT tears, increased T2 signal intensity of the LHBT exhibited high sensitivities (reviewers 1 and 2; 82.85 and 80 %, respectively) and the presence of intratendinous defects or C signs exhibited the highest specificities (reviewers 1 and 2; 95.55 and 93.33 %, respectively), followed by abnormalities in shape and outer margins of the LHBT (reviewers 1 and 2; 91.11 and 82 %; 91.11 and 86.66 %, respectively). CONCLUSION: Non-contrast-enhanced 3T shoulder MRI is potentially highly accurate in detection of complete LHBT tears, but moderately accurate in detection of partial LHBT tears. PMID- 27717976 TI - Coexisting sarcoidal granulomatous inflammation and diffuse tenosynovial giant cell tumor of the knee after a total knee replacement: a case report. AB - Sarcoidosis is a systemic inflammatory disorder characterized by non-caseating granulomas, predominantly involving lung, mediastinal lymph nodes and other organs. Synovium involvement is infrequent, and as far as we know, involvement of a periprosthetic membrane has not been reported in the English literature. Intra articular diffuse tenosynovial giant cell tumor ("conventional diffuse pigmented villonodular synovitis") is an uncommon, locally aggressive neoplasm with few previous case reports in which it arose in periprosthetic tissues after knee arthroplasty. We describe a unique case of an intraarticular mass next to a total knee prosthesis implanted 6 years ago in a patient with a history of pulmonary sarcoidosis. Clinically, this 67-year-old gentleman presented with progressive left knee pain, effusion and marked instability. MRI showed a large complex effusion with synovial thickening in the supra patella recess and the medial and lateral gutters. In addition, a large multilobulated mass with mixed low and high signal intensity was present in the posterior joint space, extending into the popliteal area. A two-stage operation was performed. Histologically, the mass from the posterior joint space showed characteristic features of diffuse tenosynovial giant cell tumor, while the synovium from the anterior compartment demonstrated sarcoidal granulomatous inflammation. Orthopaedic wear debris was found within the giant cells of these sarcoidal granulomata. The histologic features are different from those "usual" macrophage reactions to the particles of debris. In this article, we also included two optional links (highlighted in blue in the figures) to digital whole slide image (WSI), which allow the readers to navigate the entire microscope slides. PMID- 27717977 TI - Ring finger lumbrical origin strain: a case series with imaging findings. AB - Lumbrical strain is a relatively unknown hand injury. We report four cases of lumbrical origin strain involving the ring finger flexor tendons. Three patients sustained the injury during rock climbing and one while working with a jackhammer. In all cases, circumferential fluid around the flexor tendons of the ring finger was demonstrated on MRI and/or ultrasound at the distal palmar level at the "bare area," which is normally devoid of a synovial sheath. There is a paucity of information in the literature regarding this injury and its specific imaging features. Lack of awareness of this injury renders accurate diagnosis difficult. PMID- 27717978 TI - High-resolution ultrasound in the diagnosis of trigger finger and evaluation of response to steroid injection. AB - OBJECTIVE: No studies have reported the use of ultrasound for the evaluation of trigger finger after steroid injection. We evaluated the clinical features and ultrasound appearance of trigger finger before and after steroid injection under ultrasound guidance. MATERIALS AND METHODS: Thirty-eight digits with triggering were included. A single steroid injection into the tendon sheath was administered. Ultrasound findings and clinical symptoms, including pain, triggering, and the Quinnell score, were analyzed before injection and at 1 and 3 weeks after injection. RESULTS: Ultrasound indicated that the thickness of the flexor tendons and the thickness of A1 pulleys were significantly greater in the trigger fingers than in controls before steroid injection. Three weeks after injection, these two parameters decreased, and there was no significant difference in the two parameters between the trigger finger and the controls. The visual analogue scales at 1 and 3 weeks after the injection were significantly lower than those before the injection. The Quinnell grading system scores significantly improved at 1 and 3 weeks after injection compared with the scores before injection. Moreover, a tendency was seen for the more clinically severe cases to show more swelling of the tendon and pulley. CONCLUSION: In conclusion, ultrasound assessments could reveal that the thickened A1 pulley and flexor tendon significantly improved after steroid injection, which enables us to confirm the therapeutic effects of the steroid injection. Therefore, ultrasound assessments can be a useful adjunct to understand the response to treatment with the steroid injection. PMID- 27717979 TI - Abdominal manifestations of fishbone perforation: a pictorial essay. AB - PURPOSE: The present article provides an overview of the spectrum of abdominal presentations of fishbone (FB) ingestion and its complications. METHODS: In image data from 9 patients, FB perforations were found in different levels of the gastrointestinal tract (GIT), including duodenal, jejunal, and sigmoid perforations; in 4 asymptomatic patients, FBs were observed in the mesentery, falciform ligament, and intestinal bowel. RESULTS: The main imaging features of FB perforation were focal gastric or intestinal wall thickening, fat stranding, bowel obstruction, ascites, localized pneumoperitoneum, intra-abdominal abscess, liver abscess, and a linear hyperdense structure in the abdominal cavity in the GIT or within a parenchymal organ often surrounded by inflammatory changes. Free pneumoperitoneum was rare. CONCLUSION: Although in most cases, a FB does not cause any serious complications, an inflammatory process and complications may occur when it perforates the stomach or bowel loops. Radiologists need to be aware of the possibility of FB perforation, especially in high-risk patients, because it is not always considered in the differential diagnosis by referring physicians and can mimic other inflammatory conditions and tumoral lesions. PMID- 27717981 TI - ? PMID- 27717980 TI - Quantitative analysis of the right auricle with 256-slice computed tomography. AB - PURPOSE: To quantitatively measure the morphology parameters of the right auricle with 256-slice multidetector computed tomography angiography (MDCTA) in healthy people. MATERIALS AND METHODS: A retrospective analysis of 200 patients who had undergone coronary MDCTA with negative findings was performed. The raw imaging data were reconstructed and the right auricular volume, right atrial volume, right auricle height, base long and short axes, base perimeter and area, normal angle, and distance were quantitatively measured. RESULTS: Men had significantly (P < 0.05) greater values than women in the right auricular volume (13.3 +/- 4.0 vs. 11.7 +/- 3.7 mL) and height (33.0 +/- 5.0 vs. 30.5 +/- 5.2 mm), the base long axis (34.4 +/- 4.1 vs. 33.2 +/- 3.9 mm), area (787.6 +/- 177.6 vs. 771.0 +/- 143.2 mm2) and perimeter (119.2 +/- 17.5 vs. 115.0 +/- 13.0), and the normal distance (22.4 +/- 6.6 vs. 20.2 +/- 6.7 mm). The normal 95 % reference range for the right auricular parameters was put forward. The right auricular parameters had a good correlation with the right atrium volume, aortic diameter, the body weight, height, and body surface area but a bad correlation with the vertebral body height. Significantly (P < 0.05) greater values were found in the normal angle and distance in subjects below than over 40 years of age. No other significant (P > 0.05) difference existed in the other right auricular parameters. CONCLUSION: Quantitative measurements of the right auricle can help us get a good understanding of the right auricular morphology and its relationship with surrounding structures and are helpful for cardiac interventions of electrophysiology and radiofrequency ablation.

PMID- 27717985 TI - Thymoquinone mitigate ischemia-reperfusion-induced liver injury in rats: a pivotal role of nitric oxide signaling pathway. AB - Oxidative and nitrosative stress-induced endothelial cell damage play an essential role in the pathogenesis of hepatic ischemia-reperfusion (IR) injury. IR is associated with reduced eNOS expression and exacerbated by superimposed stress. NOSTRIN induces intracellular endothelial nitric oxide synthase (eNOS) translocation and inducible nitric oxide synthase (iNOS) increases nitric oxide (NO) production. Our aim was to assess hepatic expression of iNOS, eNOS, and NOSTRIN in IR with or without N-acetylcysteine (NAC) or thymoquinone (TQ) pretreatment and to compare their hepatoprotective effects. Surgical induction of IR was performed by occlusion of hepatic pedicle for 30 min with mini-clamp and reperfused for 30 min. The effects of TQ (20 mg/kg/day) or NAC (300 mg/kg/day) administered orally for 10 days were evaluated by serum ALT and AST, oxidative stress parameters, NO production, and histopathological analysis. Also, localization and expression of iNOS, eNOS, and NOSTRIN were assessed by immunofluorescence. TQ or NAC pretreatment significantly decreased elevated serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and myeloperoxidase (MPO) activities, malondialdehyde (MDA) level, and NO production. In addition, they restored the depleted GSH content and alleviated histopathological changes. Furthermore, they up-regulated eNOS and down-regulated iNOS and NOSTRIN expressions. TQ exerts its hepatoprotective effect, at least in part, by nitric oxide signaling pathway through modulation of iNOS, eNOS, and NOSTRIN expressions as well as suppression of oxidative stress. PMID- 27717988 TI - MHC class II beta exon 2 variation in pardalotes (Pardalotidae) is shaped by selection, recombination and gene conversion. AB - The high levels of polymorphism and allelic diversity which characterise genes in the major histocompatibility complex (MHC) are thought to be generated and maintained through the combined effects of different evolutionary processes. Here, we characterised exon 2 of the MHC class II beta genes in two congeneric passerine species, the spotted (Pardalotus punctatus) and striated pardalote (Pardalotus striatus). We estimated the levels of allelic diversity and tested for signatures of recombination, gene conversion and balancing selection to determine if these processes have influenced MHC variation in the two species. Both species showed high levels of polymorphism and allelic diversity, as well as evidence of multiple gene loci and putative pseudogenes based on the presence of stop codons. We found higher levels of MHC diversity in the striated pardalote than the spotted pardalote, based on the levels of individual heterozygosity, sequence divergence and number of polymorphic sites. The observed differences may reflect variable selection pressure on the species, resulting from differences in patterns of movement among populations. We identified strong signatures of historical balancing selection, recombination and gene conversion at the sequence level, indicating that MHC variation in the two species has been shaped by a combination of processes. PMID- 27717990 TI - Reclassification of Brevibacterium halotolerans DSM8802 as Bacillus halotolerans comb. nov. Based on Microbial and Biochemical Characterization and Multiple Gene Sequence. AB - Brevibacterium halotolerans is currently classified as a member of the Brevibacterium genus, a genus that groups together many bacterial species of similar morphology but diverse biochemical and physiological features. Here we suggest, based on multiple gene sequencing and microbial and biochemical characterization of two environmental isolates and one type strain (DSM8802), that the B. halotolerans DSM8802 (and probably the other deposited under this species name) should be re-classified into the Bacillus genus, and offered the name B. halotolerans comb. nov. PMID- 27717989 TI - Total ankle arthroplasty versus ankle arthrodesis for the treatment of end-stage ankle arthritis: a meta-analysis of comparative studies. AB - PURPOSE: Total ankle arthroplasty (TAA) and ankle arthrodesis (AA) are the main surgical treatment options for end-stage ankle arthritis. Although the superiority of each modality remains debated, there remains a lack of high quality evidence-based studies, such as randomized controlled clinical trials, and meta-analyses of comparative studies. We performed a meta-analysis of comparative studies to determine whether there is a significant difference between these two procedures in terms of (i) clinical scores and patient satisfaction, (ii) re-operations, and (iii) complications. METHODS: We conducted a comprehensive search in the MEDLINE, EMBASE, and Cochrane library databases. Only retrospective or prospective comparative studies were included in this meta analysis. The literature search, data extraction, and quality assessment were conducted by two independent reviewers. The primary outcomes were clinical scores and patient satisfaction. We also investigated the prevalence of complications and the re-operation rate. RESULTS: Ten comparative studies were included (four prospective and six retrospective studies). There were no significant differences between the two procedures in the American Orthopaedic Foot and Ankle Society ankle-hindfoot score, Short Form-36 physical component summary and mental component summary scores, visual analogue scale for pain, and patient satisfaction rate. The risk of re-operation and major surgical complications were significantly increased in the TAA group. CONCLUSIONS: The meta-analysis revealed that TAA and AA could achieve similar clinical outcomes, whereas the incidence of re-operation and major surgical complication was significantly increased in TAA. Further studies of high methodological quality with long-term follow-up are required to confirm our conclusions. PMID- 27717991 TI - [Bifurcation lesions : How should they be assessed and treated?] AB - Bifurcation lesions are a therapeutic challenge in the interventional treatment of coronary artery disease. Thus, consideration of anatomical aspects and selection of the most appropriate strategy for an individual bifurcation have an impact on the interventional outcome. Accordingly, assessment of the type of bifurcation stenosis, including the relevance of the side branches, vessel diameter and the angle between the two branches are critical for the optimal choice of interventional strategy. The fractional flow reserve (FFR) is a parameter that provides a measure of the severity of coronary stenosis and despite some limitations, FFR can be applied to bifurcation lesions. In addition, intravascular imaging tools, such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) can be used to determine anatomical configurations. PMID- 27717992 TI - Residential Knowledge of Native Tree Species: A Case Study of Residents in Four Southern Ontario Municipalities. AB - In the past decade, municipalities across North America have increased investment in their urban forests in an effort to maintain and enhance the numerous benefits provided by them. Some municipalities have now drafted long-term urban forest management plans that emphasize the planting of native trees, to improve ecological integrity, and participation of residents, since the majority of urban trees are typically located on residential property. Yet it is unclear if residents are familiar with native trees or municipalities' urban forest management goals. Through a case study of southern Ontario municipalities, we administered a survey exploring residents' ability to correctly label common tree species as native or non-native, as well as their knowledge of urban forest management plans to test four hypotheses: 1) residents in municipalities with an urban forest management plans will be more knowledgeable about the native status of common street trees; 2) residents who have lived in the area longer will have greater knowledge; 3) knowledge level will be correlated with education level, ethnicity, and income; and 4) residents' knowledge will be related to having planted trees on their property. Our results indicate that residents are better able to identify common native trees than correctly determine which trees are non native, although knowledge levels are generally low. Knowledge was significantly related to length of residency and tree planting experience, supporting hypotheses 2 and 4. These results highlight the importance of experience and local knowledge acquisition in relation to basic knowledge about urban trees, and also point to the failures of resident outreach within the case study municipalities. PMID- 27717993 TI - Imatinib dose reduction in patients with chronic myeloid leukemia in sustained deep molecular response. AB - To determine whether a lower imatinib dose could minimize toxicity while maintaining the molecular response (MR), imatinib dose was reduced to 300 mg daily in 43 patients with chronic myeloid leukemia (CML) in sustained deep molecular response to first-line imatinib 400 mg daily. At the time of dose reduction, median duration of the deep response was 4.1 (interquartile range (IQR) 2.2-5.9) years; molecular response was MR4, MR4.5, and MR5 of the international scale in 6, 28, and 9 patients, respectively. Toxicity grade was 1, 2, and 3 in 28, 8, and 1 patients, respectively; 6 patients underwent dose reduction without having side effects. With a median of 1.6 (IQR 0.7-3.2) years on imatinib 300 mg daily, only one patient lost the deep molecular response to MR3. At the last follow-up, response was MR3, MR4, MR4.5, and MR5 in 1, 3, 9, and 30 patients, respectively. Toxicity improvement was observed in 23 (62.2 %) of the 37 patients with side effects, decreasing to grade 0 in 20 of them. All but one anemic patients improved (p = 0.01), the median Hb increase in this subgroup of patients being 1 g/dL. In CML patients with sustained deep response to the standard imatinib dose, reducing to 300 mg daily significantly improves tolerability and preserves efficacy. PMID- 27717994 TI - Simultaneous assessment of hand function and neuromuscular quickness through a static object manipulation task in healthy adults. AB - Both hand function [as seen through the coordination between grip force (GF) and load force (LF)] and the ability to produce a submaximal force quickly (i.e., neuromuscular quickness) are two important qualities of motor function that could be seriously affected by the presence of neurological diseases. Therefore, their quantitative assessment is very important in clinical settings. Within this study, we aimed to develop, standardize, and measure the within-session reliability of a clinically meaningful test that assesses both hand function and neuromuscular quickness simultaneously. Thirteen healthy young adults produced around 90 rapid isometric LF pulses to varying submaximal magnitudes by either pulling down or pulling up on an externally fixed GF- and LF-measuring device. Results revealed high indices of force coordination (i.e., GF scaling as assessed by GF/LF and GF coupling as assessed by maximum cross-correlation between GF and LF) in both force directions, while GF coupling was higher in downward than in upward direction (p < 0.001). Regarding the indices of neuromuscular quickness (i.e., the regression parameters obtained from the relationship between peak force and it's rate of development and half-relaxation time), results, in general, revealed a higher slope (named as rate of force development scaling factor; p < 0.01), similar R 2 (p > 0.05), and shorter half-relaxation time (p < 0.05) for LF than for GF. Furthermore, all of the selected variables showed moderate to excellent within-session reliability with only 45 pulses. Findings suggest that brief force production tasks should be further evaluated as clinical tests of hand function and neuromuscular quickness in various populations. PMID- 27717995 TI - Juvenile myelomonocytic leukemia presenting as bilateral breast masses. AB - An 8-year-old girl presented with bilateral breast masses and was subsequently diagnosed with juvenile myelomonocytic leukemia. Juvenile myelomonocytic leukemia is a rare myelodysplastic syndrome that typically presents in boys younger than 3 years of age with splenomegaly, lymphadenopathy and skin findings. Bilateral breast masses in a child are rare and, as such, present a diagnostic dilemma due to the relative paucity of cases in the literature. We present a case of granulocytic sarcoma of the breasts in a patient with juvenile myelomonocytic leukemia. The authors hope that increased reporting and research regarding pediatric breast masses will help create awareness for such cases.

PMID- 27717996 TI - A comparison of efficacy of doxazosin 4 and 8 mg in medical expulsive therapy of distal ureteral stones: a prospective randomized clinical trial. AB - We aimed to investigate the efficacy of two different doses of doxazosin, 4 and 8 mg, in medical expulsive therapy (MET). This prospective randomized study included a total of 66 patients with distal ureteral stones which were radio opaque and <=10 mm. All patients were randomly divided into three groups: Group 1 included 25 patients receiving 4 mg doxazosin. Group 2 included 22 patients receiving 8 mg doxazosin. Diclofenac 100 mg p.o. and daily 1500-2000 cc hydration were advised to the patients in Groups 1 and 2 to relieve pain. Group 3 consisted of 19 patients who were defined as control group and received only hydration and analgesics. The mean age of the patients was 30 +/- 7.6, 37.9 +/- 11.5 and 33 +/- 11.3 in Group 1, Group 2 and Group 3, respectively. The mean stone size was 6.6 +/- 1.4, 7.1 +/- 1.5 and 6.6 +/- 1.5 in Group 1, Group 2 and Group 3, respectively. The stone expulsion rate of the patient groups was 18/25 (72 %), 15/22 (68.1 %) and 5/19 (25.3 %). There were significantly fewer pain episodes and lower analgesic requirement in Groups 1 and 2 (p = 0.021). However, the difference between Group 1 and Group 2 was non-significant (p = 0.207). Given the data of the present study, doxazosin, an alpha receptor blocker, exhibited equal efficacy with 4 or 8 mg doses in MET and was used safely and efficiently in ureteral stones <10 mm. The findings of the present study showed that 4 mg dose is effective, when doxazosin is preferred for MET. PMID- 27717998 TI - Lymphocyte function following radium-223 therapy in patients with metastasized, castration-resistant prostate cancer. AB - PURPOSE: Therapy with the alpha-emitter radium-223 chloride (223Ra) is an innovative therapeutic option in patients with metastasized, castration-resistant prostate cancer. However, radiotherapy can lead to hematopoietic toxicity. The aim of this study was to determine if 223Ra therapy induces an impairment of cellular antimicrobial immune responses. METHODS: In 11 patients receiving 223Ra treatment, lymphocyte proliferation and the production of pro- and anti inflammatory cytokines (interferon-gamma and interleukin-10) were determined, using lymphocyte transformation testing and ELISpot, respectively. Lymphocyte function after stimulation with mitogens and microbial antigens was assessed prior to therapy and at day 1, 7 and 28 after therapy. RESULTS: Lymphocyte proliferation and the production of interferon-gamma and interleukin-10 towards mitogens and antigens remained unchanged after therapy. Consistent with these in vitro data, we did not observe infectious complications after treatment. CONCLUSIONS: The results argue against an impairment of lymphocyte function after 223Ra therapy. Thus, immune responses against pathogens should remain unaffected. PMID- 27717999 TI - Effect of bosutinib on the absorption of dabigatran etexilate mesylate, a P glycoprotein substrate, in healthy subjects. AB - PURPOSE: Bosutinib, a dual Src and Abl tyrosine kinase inhibitor for the treatment of chronic myeloid leukemia, demonstrated concentration-dependent inhibitory effects on P-glycoprotein (P-gp)-mediated digoxin efflux in vitro, suggesting that bosutinib may inhibit P-gp substrates. The effect of bosutinib on dabigatran etexilate mesylate (EM) absorption, a P-gp substrate, was evaluated. METHODS: In this open-label, randomized, single-dose, one-cohort, two-sequence, two-period crossover study, healthy, fed subjects received dabigatran EM (150 mg * 1 orally) alone or 1 h after receiving bosutinib tablets (100 mg * 5 orally). RESULTS: Dabigatran EM monotherapy and concurrent administration of dabigatran EM with bosutinib resulted in similar values for concentration time curves from time zero extrapolated to infinity (AUCinf), but slightly lower maximum plasma concentration (C max) values (AUCinf, 1182 and 1186 ng.h/mL, respectively; C max, 129.8 and 114.1 ng/mL). The time to maximum concentration for dabigatran was 2.99 and 3.99 h for combination therapy. The ratio of the adjusted geometric means (test/reference) of dabigatran AUCinf and C max (90 % confidence interval) were 101.4 % (89.6-114.9 %) and 89.7 % (77.8-103.4 %), respectively, following administration of dabigatran EM with bosutinib (test) relative to dabigatran EM administered alone (reference). Six subjects receiving combination treatment reported a total of seven adverse events (AEs) versus none for subjects receiving monotherapy alone. All AEs were mild to moderate and considered treatment related. CONCLUSION: These data demonstrate that single doses of bosutinib do not affect dabigatran exposure, suggesting that bosutinib is not a clinical inhibitor of P-gp.

PMID- 27718000 TI - Effect of aprepitant, a moderate CYP3A4 inhibitor, on bosutinib exposure in healthy subjects. AB - PURPOSE: Bosutinib is an oral, dual Src and Abl tyrosine kinase inhibitor (TKI) approved for the treatment of Philadelphia chromosome-positive chronic myeloid leukemia resistant or intolerant to prior TKI therapy. Bosutinib is primarily metabolized by cytochrome P450 (CYP) 3A4, suggesting drug interaction potential with other CYP3A4 modulators. This open-label, randomized, 2-sequence, 2-period crossover study assessed the effect of single-dose aprepitant, a moderate CYP3A4 inhibitor, on the single-dose pharmacokinetic profile of oral bosutinib 500 mg. METHODS: Nineteen healthy, fed adults received bosutinib (100 mg * 5) alone or coadministered with aprepitant (125 mg * 1) in each treatment period (with a >=14 day washout); serial blood samples were analyzed. Safety was evaluated. RESULTS: Following coadministration of aprepitant with bosutinib, the area under the concentration-time curve from time zero extrapolated to infinity (AUCinf) and maximum plasma concentration (C max) were higher than in bosutinib alone (AUCinf, 4719 and 2268 ng*h/mL; C max, 146.0 and 94.94 ng/mL). For bosutinib with aprepitant versus bosutinib alone, mean terminal elimination half-life was similar (25.99 vs 27.79 h), time to C max was longer (6.02 vs 4.15 h), and apparent oral clearance (CL/F) was decreased (105.9 vs 220.4 L/h). The ratio of adjusted geometric means of AUCinf and C max for bosutinib with aprepitant relative to bosutinib alone were 199 % (90 % confidence interval, 167-237 %) and 153 % (127-184 %), respectively. Both treatments were well tolerated. CONCLUSION: In healthy volunteers, administering a single dose of aprepitant increased the AUC and C max following a single dose of bosutinib by 99 and 53 %, respectively. These results are consistent with a moderate CYP3A4 inhibitor effect of aprepitant on bosutinib (Trial Registration: ClinicalTrials.gov NCT02058277). PMID- 27718001 TI - Surgery-Related Muscle Loss and Its Association with Postoperative Complications After Major Hepatectomy with Extrahepatic Bile Duct Resection. AB - BACKGROUND: Several studies have reported that preoperative sarcopenia negatively impacts postoperative outcomes. Meanwhile, changes in skeletal muscle mass during the acute phase after surgery and their association with postoperative complications are unknown. OBJECTIVE: The objective of this study was to investigate the relation between changes in skeletal muscle mass and postoperative complications after major hepatectomy with extrahepatic bile duct resection. METHODS: This study included 254 patients who underwent major hepatectomies with extrahepatic bile duct resections. Total psoas muscle area (TPA) was measured using abdominal computed tomography images obtained before and 1 week after surgery. The percent change in TPA after surgery was calculated. Patients were stratified by sex-specific tertiles according to the extent of muscle mass change by percentage. Surgery-related muscle loss (SML) was defined as the lowest tertile of percent change in TPA. RESULTS: Male patients with a percent change of TPA lower than -5.0 % (n = 54) and female patients with that lower than -2.6 % (n = 31) were included in the lowest tertile and were categorized into a group with SML. The incidence rates of major complications, pancreatic fistula, infectious complications, and mortality were all significantly higher in the group with SML than in the group without SML. By multivariate analyses, SML was identified as an independent factor associated with major complications (odds ratio 3.21; 95 % confidential interval 1.82-5.76, p < 0.001). CONCLUSIONS: SML is significantly associated with postoperative morbidity and mortality in patients who underwent major hepatectomies with extrahepatic bile duct resections.

AB - BACKGROUND: Sublobar resection of lung cancer may benefit patients with lung cancer presenting as ground-glass opacity (GGO) nodules. The purpose of this study was to evaluate the effect of margin width on recurrence after sublobar resection in patients with clinical N0 non-small cell lung cancer presenting as GGO-predominant nodule. METHODS: We conducted a retrospective chart review of 91 patients treated for clinical N0 non-small cell lung cancer <=3 cm by sublobar resection with clear resection margins. We assigned them to two groups: GGO predominant tumor and solid-predominant tumor. Each group was subdivided into two groups according to the margin width: resection margin <=5 mm and resection margin >5 mm. We analyzed the clinicopathological findings and survival among these four groups. RESULTS: There was no recurrence in GGO-predominant tumors after sublobar resection. Margin width did not influence the recurrence in GGO predominant tumors. In the cases of solid-predominant tumor, 5-year recurrence free survival after sublobar resection according to margin width <=5 and >5 mm was 24.2 and 79.6 %, respectively (p < 0.001). Therefore, narrow margin width (resection margin <=5 mm) was a significant risk factor for recurrence of solid predominant tumors (hazard ratio 3.868, 95 % confidence interval 1.177-12.714, p = 0.026). CONCLUSIONS: The width between the tumor and resection margin does not affect the recurrence after R0 sublobar resection in patients with clinical N0 GGO-predominant lung cancer <=3 cm. By contrast, margin width is a significant risk factor for recurrence after sublobar resection in patients with clinical N0 solid-predominant lung cancer. PMID- 27718003 TI - Multifocal Versus Solitary Papillary Thyroid Carcinoma. PMID- 27718004 TI - A Clear Difference Between the Outcomes After a Major Hepatectomy With and Without an Extrahepatic Bile Duct Resection. AB - BACKGROUND: The procedure of a simple hepatectomy and a hepatectomy with an extrahepatic bile duct resection and subsequent choledocho-jejunostomy is largely different. However, these two procedures are sometimes included in the same category. There are no studies comparing postoperative course and liver regeneration rate after a major hepatectomy with and without an extrahepatic bile duct resection. METHODS: We retrospectively reviewed medical records of 245 patients who underwent a right hepatectomy (RH, n = 55) or RH with an extrahepatic bile duct resection (RHEBR, n = 190). Postoperative complications, including incidence of posthepatectomy liver failure (PHLF) and hepatic regeneration rates after surgery, were evaluated. RESULTS: The incidence of PHLF was considerably higher in the RHEBR group than in the RH group (39.5 vs. 16.4 %, p = 0.001). The percentage of newly regenerated liver volume after the hepatectomies on postoperative days 6-8 was significantly lower in the RHEBR group than in the RH group (14.0 % in the RH; 7.9 % in the RHEBR group, p < 0.001). Especially type of surgery (RHEBR) was the only independent risk factor for an impaired liver regeneration rate by univariate and multivariate analyses. Furthermore, estimated hepatic regeneration rate by stepwise linear regression analysis in the RHEBR group was 7.1 % lower (95 % confidence interval 1.8-12.3, p = 0.011) than in the RH group. CONCLUSION: These results suggest that the procedure of extrahepatic bile duct resection has a possibility of adverse impact on the postoperative outcome after major hepatectomy. PMID- 27718005 TI - Readmissions After Surgery: A French Nationwide Cross-Sectional Study of 1,686,602 Procedures Performed in 2010. AB - BACKGROUND: Surgical readmissions have been extensively studied in North America, but very few data from other countries are available. We aimed to describe surgical readmissions in France and to assess their association with hospital status, surgical volume, and day surgery activity. METHODS: We performed a cross sectional study encompassing all 1270 French hospitals, except for military hospitals and hospitals with very small volume. Data were retrieved from the national database regarding all patients undergoing surgery between January 1, 2010 and November 30, 2010. The main outcome measure was 30-day readmission rate. Association with hospital status, surgical volume, and the level of day surgery were assessed. Risk adjustment was performed based upon administrative categories. RESULTS: After exclusion of deaths and hospital transfers, there were 1,686,602 patients in the study cohort. Thirty-day readmission rate was 5.9 %. Distribution was skewed, with 21.5 % of procedures accounting for 33.5 % of all 30-day readmissions. Early readmissions (<=3 days) were associated with higher mortality as compared to those occurring later (>7 days) (3.2 vs. 2.6 %; p < 0.0001). After multivariate analysis, University hospitals were shown to be affected by a significantly greater risk of 30-day readmission as compared to private hospitals (odds ratio 1.46 [95 % CI 1.42-1.5]). Other independent factors were as follows: male gender, longer initial hospital stay, and comorbidities. CONCLUSIONS: Surgical 30-day readmission rate was low, with early readmissions being associated with higher mortality. Conversely to prior research, University hospitals were shown to be associated with significantly higher risk of 30-day readmissions, even after risk adjustment. PMID- 27718007 TI - Degradation Processes of Pesticides Used in Potato Cultivations. AB - Potato is one of the most important crops, after maize, rice and wheat. Its global production is about 300 million tons per year and is constantly increasing. It grows in temperate climate and is used as a source of starch, food, and in breeding industry.Potato cultivation requires application of numerous agro-technical products, including pesticides, since it can be affected by insects, weeds, fungi, and viruses. In the European Union the most frequently used pesticides in potato cultivations check are: thiamethoxam, lambda cyhalothrin and deltamethrin (insecticides), rimsulfuron (herbicide) and metalaxyl (fungicide).Application of pesticides improves crop efficiency, however, as pesticides are not totally selective, it affects also non-target organisms. Moreover, the agrochemicals may accumulate in crops and, as a consequence, negatively influence the quality of food products and consumer health. Additional risks of plant protection products are related to their derivatives, that are created both in the environment (soil, water) and in plant organisms, since many of these compounds may exhibit toxic effects.This article is devoted to the degradation processes of pesticides used in potato crop protection. Attention is also paid to the toxicity of both parent compounds and their degradation products for living organisms, including humans. Information about the level of pesticide contamination in the environment (water, soil) and accumulation level in edible plants complement the current knowledge about the risks associated with widespread use of thiamethoxam, lambda-cyhalothrin and deltamethrin, rimsulfuron and metalaxyl in potato cultivation. PMID- 27718008 TI - Influence of Nanotoxicity on Human Health and Environment: The Alternative Strategies. AB - Currently, nanotechnology revolutionizing both scientific and industrial community due to their applications in the fields of medicine, environmental protection, energy, and space exploration. Despite of the evident benefits of nanoparticles, there are still open questions about the influence of these nanoparticles on human health and environment. This is one of the critical issues that have to be addressed in the near future, before massive production of nanomaterials. Manufactured nanoparticles, which are finding ever-increasing applications in industry and consumer products fall into the category of emerging contaminants with ecological and toxicological effects on populations, communities and ecosystems. The existing experimental knowledge gave evidence that inhaled nanoparticles are less efficiently separated than larger particles by the macrophage clearance mechanisms and these nanoparticles are known to translocate through the lymphatic, circulatory and nervous systems to many tissues and organs, including the brain. In this review we highlight adverse impacts of nanoparticles on human and the environment with special emphasis on green nanoscience as a sustainable alternative. PMID- 27718006 TI - Graft dislocation and graft failure following Descemet membrane endothelial keratoplasty (DMEK) using precut tissue: a retrospective cohort study. AB - PURPOSE: Although the functional results following DMEK are better than after DSAEK, DSAEK still seems to be the standard procedure, as surgeons fear losing grafts during DMEK graft preparation. Therefore, eye banks offer precut DMEK grafts for direct use by the surgeon. Here, we analysed the functional results and complication rates for a precut technique compared to fresh preparations. METHODS: We retrospectively compared 453 standard to 11 precut (1-2 days before surgery) DMEK cases. Precut preparations did not differ from the standard preparation, except that the preparation was stopped after trephination with the graft still attached in a small central area. The preparation had to be completed before surgery by peeling off the centrally attached part of the graft. This technique was first tested in an experimental series of 14 grafts, which were unsuitable for transplantation. All surgeries were performed in the same standardized way. RESULTS: There was no significant endothelial cell loss during the storage period following precut preparation. We found a statistically significantly higher endothelial cell loss and graft failure rate for the precut grafts. CONCLUSION: Because of the statistically significant higher graft failure rate in the precut group, we stopped using this technique, so the numbers in this retrospective case series are small. The higher graft failure rate may be explained by (ultra)structural changes in the DMEK graft (e.g. accumulation of dextran) during the second storage period. Therefore, careful evaluation is recommended before using precut DMEK grafts stored in dextran containing media in order to avoid early primary graft failures. PMID- 27718010 TI - From "ear" to there: a review of biorobotic models of auditory processing in lizards. AB - The peripheral auditory system of lizards has been extensively studied, because of its remarkable directionality. In this paper, we review the research that has been performed on this system using a biorobotic approach. The various robotic implementations developed to date, both wheeled and legged, of the auditory model exhibit strong phonotactic performance for two types of steering mechanisms-a simple threshold decision model and Braitenberg sensorimotor cross-couplings. The Braitenberg approach removed the need for a decision model, but produced relatively inefficient robot trajectories. Introducing various asymmetries in the auditory model reduced the efficiency of the robot trajectories, but successful phonotaxis was maintained. Relatively loud noise distractors degraded the trajectory efficiency and above-threshold noise resulted in unsuccessful phonotaxis. Machine learning techniques were applied to successfully compensate for asymmetries as well as noise distractors. Such techniques were also successfully used to construct a representation of auditory space, which is crucial for sound localisation while remaining stationary as opposed to phonotaxis-based localisation. The peripheral auditory model was furthermore found to adhere to an auditory scaling law governing the variation in frequency response with respect to physical ear separation. Overall, the research to date paves the way towards investigating the more fundamental topic of auditory metres versus auditory maps, and the existing robotic implementations can act as tools to compare the two approaches. PMID- 27718009 TI - Environmental and occupational exposure to bisphenol A and endometriosis: urinary and peritoneal fluid concentration levels. AB - OBJECTIVES: The study aimed to give a first data set of bisphenol A (BPA) levels in the peritoneal fluid of patients suffering from endometriosis and to investigate the relationship between BPA exposure and endometriosis. METHODS: A questionnaire investigating the occupational context, life environment, and habits was administered to 68 patients suffering from endometriosis and 60 endometriosis-free subjects (control group). Urine and peritoneal fluids samples were collected and analysed by GC/MSMS for BPA dosage. RESULTS: Some of the investigated environmental/lifestyle risk factors (closeness to industries/activities at risk) were associated with an increase in endometriosis; smoking resulted as protective factor; others (use of food plastic boxes) did not seem to influence the onset of pathology. The association between the occupational exposure summarising all examined risk factors (working activity, personal protective equipment, seniority) and endometriosis was statistically significant (chi 2 = 5.252, p = 0.02). Contrasting results were obtained when specific activities were examined. Detectable urinary BPA levels were found in all analysed samples (patients: 1.17-12.68 pg/ul; mean +/- SD, 5.31 +/- 3.36 pg/ul; control group: 1.28-2.35 pg/ul; mean +/- SD, 1.64 +/- 0.49 pg/ul; median; 1.46 pg/ul), with a statistically significant difference between patients and controls, showing an association between BPA exposure and endometriosis. Only a few subjects from the control group supplied peritoneal fluid; hence, no comparison test with patients (range 0.39-1.46 pg/ul; mean +/- SD, 0.67 +/- 0.30 pg/ul; median, 0.58 pg/ul) was carried out. CONCLUSIONS: Results highlight the potential association between BPA exposure and endometriosis, as well as the current lack of knowledge regarding occupational exposure to BPA and the need of epidemiological studies focused on single activities/occupations, such as housewives, cleaners, students. PMID- 27718011 TI - Gun barrel view of the anterior pelvic ring for percutaneous anterior column or superior pubic ramus screw placement. AB - BACKGROUND: Traditionally, operative fixation of pelvic and acetabular injuries involves complex approaches and significant complications. Accelerated rehabilitation, decreased soft tissue stripping and decreased wound complications are several benefits driving a recent interest in percutaneous fixation. We describe a new fluoroscopic view to guide the placement of screws within the anterior pelvic ring. METHODS: Twenty retrograde anterior pelvic ring screws were percutaneously placed in ten cadaveric specimens. Arranging a standard C-arm in a position similar to obtaining a lateral hip image, with angles of 54 degrees +/- 2 degrees beam to body, 75 degrees +/- 5 degrees of reverse cantilever and 14 degrees +/- 6 degrees of outlet, a gun barrel view of the anterior pelvic ring is identified. Fluoroscopic images were taken, and the hemipelvi were harvested to examine the dimensions of the anterior pelvic ring and inspected for any cortical or articular perforation. RESULTS: The minimum cranial-to-caudal distance in the anterior pelvic ring was 9 mm (range 6.5-12 mm), and the minimum anterior-to-posterior dimension was 9 mm (range 5-15 mm). All but 2 screws were completely confined within the osseous corridors. Identifiable on final fluoroscopic evaluation, one screw perforated the psoas groove and a second perforated the acetabular dome. Overall, 90 % of our screws were accurately and safely placed, upon the first attempt, within the anterior pelvic ring using the described gun barrel view. CONCLUSION: Employing either open reduction, or following a closed or percutaneous reduction, the anterior pelvic ring gun barrel view can reproducibly guide safe placement of anterior pelvic ring screw fixation. LEVEL OF EVIDENCE: IV. PMID- 27718012 TI - In Japanese patients with papillary thyroid carcinoma, TERT promoter mutation is associated with poor prognosis, in contrast to BRAF V600E mutation. AB - The prognostic value of BRAF V600E and TERT promoter mutation in papillary thyroid carcinoma (PTC) is controversial. We examined alterations in BRAF V600E and TERT promoter by PCR-direct sequencing in PTC of 144 Japanese patients. Alternative lengthening of telomeres was examined as another mechanism of telomere maintenance by immunohistochemical staining for ATRX and DAXX. Of the clinicopathological characteristics, regional lymph node metastasis, extra thyroid extension, multifocality/intrathyroidal spread, and advanced stage (III/V) were associated with shorter disease-free survival rate (DFSR). TERT promoter mutation was found in eight patients (6 %), and this was significantly associated with total thyroidectomy, multifocality/intrathyroidal spread, lymph node metastasis and advanced stage. The BRAF V600E mutation was found in 53 patients (38.2 %) but was not associated with any clinicopathological factors. TERT mutations were not correlated with BRAF V600E mutation status. TERT mutation positive tumors (TERT+) showed lower DFSR than BRAF V600E -mutation-positive tumors (BRAF V600E +), and TERT+/BRAF V600E + tumors showed lower DFSR than BRAF V600E + tumors. No cases showed loss of ATRX/DAXX expression by immunohistochemistry. TERT promoter mutations showed a lower prevalence in our series and appeared to be associated with aggressive behavior. In PTCs, telomerase activation by TERT promoter mutation might be more important than alternative lengthening of telomeres. PMID- 27718013 TI - A single dose of L-DOPA changes perceptual experiences and decreases latent inhibition in Parkinson's disease. AB - Despite the well-known neuropsychiatric side effects of dopaminergic medications, the possible subjective psychotomimetic effects of a single dose of L-DOPA in newly diagnosed, drug-naive patients with Parkinson's disease (PD) are not known. To investigate this question, we used a visual search task for latent inhibition (LI), the Community Assessment of Psychic Experiences (CAPE) scale, and visual analog scales for psychotomimetic effects (perception, relaxation, and dysphoria) in 28 de novo PD patients before (off) and after (on) the adminstration of L-DOPA and in 25 matched healthy control individuals. Results revealed increased LI in PD-off and decreased LI in PD-on relative to the control subjects. After the administration of L-DOPA, we observed a significant decline in LI in PD. L-DOPA also enhanced perceptual experiences (changes in subjective feelings in thinking, time perception, and mental "highness"). Greater reduction in LI was associated with enhanced perceptual experiences. These results suggest that a single dose of L-DOPA has a significant psychotomimetic effect, which is associated with decreased LI, a behavioral marker of psychosis-like experiences.

PMID- 27718014 TI - Common olfactory ensheathing glial markers in the developing human olfactory system. AB - The in situ immunocytochemical properties of olfactory ensheathing cells (OECs) have been well studied in several small to medium sized animal models including rats, mice, guinea pigs, cats and canines. However, we know very little about the antigenic characteristics of OECs in situ within the adult and developing human olfactory bulb and nerve roots. To address this gap in knowledge we undertook an immunocytochemical analysis of the 11-19 pcw human foetal olfactory system. Human foetal OECs in situ possessed important differences compared to rodents in the expression of key surface markers. P75NTR was not observed in OECs but was strongly expressed by human foetal Schwann cells and perineurial olfactory nerve fibroblasts surrounding OECs. We define OECs throughout the 11-19 pcw human olfactory system as S100/vimentin/SOX10+ with low expression of GFAP. Our results suggest that P75NTR is a robust marker that could be utilised with cell sorting techniques to generate enriched OEC cultures by first removing P75NTR expressing Schwann cells and fibroblasts, and subsequently to isolate OECs after P75NTR upregulation in vitro. O4 and PSA-NCAM were not found to be suitable surface antigens for OEC purification owing to their ambiguous and heterogeneous expression. Our results highlight the importance of corroborating cell markers when translating cell therapies from animal models to the clinic.

AB - Parasites are significant groups for carcinogenesis among which liver flukes, including Opisthorchis viverrini and Clonorchis sinensis, are typical representatives causing cholangiocarcinoma (CCA), the second most common primary hepatic malignancy with dismal prognosis. O. viverrini is prevalent in Southeast Asia, infecting 10 million people while C. sinensis has a wider distribution in East Asia and several Southeast Asian countries, affecting more than 35 million people's health. These two worms have some common characteristics and/or discrepancies in life cycle, genome, and transcriptome. As hot spots in recent years, genome and transcriptome research has extracted numerous novel fluke worm derived proteins, which are excellent for carcinogenic exploration. However, just a handful of these studies have focused on the metabolic pathway. In this study, the main mechanisms of carcinogenesis of both worms, in terms of mechanical damage, metabolic products and immunopathology, and other possible pathways, will be discussed in detail. This review retrospectively describes the main traits of C. sinensis and O. viverrini, their molecular biology and core carcinogenic mechanisms in a contrast pattern. PMID- 27718018 TI - Clinical, biochemical, and radiological characterization of the calcinosis in a cohort of Mexican patients with systemic sclerosis. AB - Calcinosis is a frequent complication of systemic sclerosis (SSc) that is usually located in extremities but may occur across the board. The aim of our study was to identify and quantify the distribution of calcinosis in a cohort of Mexican patients with SSc and its association with clinical features and autoantibodies. A cohort of patients with SSc (2013 ACR/EULAR criteria), classified in diffuse cutaneous (dcSSc) and limited cutaneous (lcSSc) (Le Roy criteria), was studied. For their analysis, patients were allocated into those with and without calcinosis (clinical and/or radiological). The evaluation included the modified Rodnan scale for skin and Medsger disease severity scale (DSS). Calcium, phosphorus, vitamin D, and parathyroid hormone (PTH) and antinuclear antibodies and extractable nuclear antigens were determined in serum. A total of 109 patients were included, 41 (37 %) with and 68 (63 %) without calcinosis. Calcinosis was more frequent in patients with dcSSc (55 vs 27 %). In total, we identified 354 sites with calcinosis and mean per patient of 12.0 +/- 9.1; the most common sites affected were the hands (83 %), proximal upper extremity (27 %), and proximal lower extremity (22 %). Patients with calcinosis had a higher score of Rodnan scale, Mesdger DSS, and frequency of anti-nucleolar and anti-Scl 70 antibodies compared to those without calcinosis. Abnormal PTH elevation was found in 35 % of patients with calcinosis and 23 % without it. The prevalence of calcinosis is high in Mexican patients with SSc, especially in diffuse variety, and is associated with increased severity of disease.

PMID- 27718020 TI - Prediction of in-hospital mortality and morbidity using high-sensitivity C reactive protein after burr hole craniostomy. AB - BACKGROUND: The purpose of this study was to assess whether preanesthetic laboratory values can predict in-hospital mortality and morbidity in patients who have undergone burr hole craniostomy due to chronic subdural hematoma. METHODS: From January 2007 to February 2016, the records of 502 consecutive patients who underwent burr hole craniotomy were analyzed. All cases of burr hole craniostomy were fitted with a drain, as required by our institutional protocol. RESULTS: Patients' demographic data and preoperative laboratory values were subjected to logistic regression analysis to predict in-hospital mortality and morbidity after burr hole craniostomy. Hemoglobin, prothrombin time, activated partial thromboplastin time, serum glucose, and high-sensitivity C-reactive protein (hsCRP) were found to be significantly associated with in-hospital mortality and morbidity by univariate regression analysis, but of these, only hsCRP (hazard ratio 1.210, 95 % confidence interval 1.089-1.345, P < 0.001) was found to significantly predict in-hospital mortality and morbidity by multivariate regression analysis. Areas under the curve for predicting in-hospital mortality and morbidity were 0.765 (95 % confidence interval 0.624-0.906, P = 0.002) and 0.646 (0.559-0.733, P = 0.001), respectively. CONCLUSIONS: Preoperative hsCRP was found to be an independent predictor of in-hospital mortality and morbidity after burr hole craniostomy due to chronic subdural hematoma. PMID- 27718021 TI - Donkin psychosis. AB - Donkin psychoses are eclamptic psychoses without seizures. As symptomatic psychoses resulting from cerebral endothelial damage, they may explain the lucid intervals that sometimes occur between eclampsia and the eruption of psychosis. They have the same features as eclamptic psychoses, with onset during pregnancy or the early puerperium, especially in first-time mothers, a short duration and full recovery in most. The clinical picture is usually delirium, but mania is also seen, and some patients have retrograde amnesia or other cognitive defects. Donkin psychosis should be considered in the differential diagnosis of childbearing psychoses, and collaborative research is needed to clarify their differences.

PMID- 27718023 TI - Expression of caspase 3 in ovarian follicle cells of the lizard Podarcis sicula. AB - In this study, our aim was to determine whether caspase 3 plays a role, during previtellogenesis, in the ovarian follicular epithelium of the lizard Podarcis sicula. We investigated the presence and localization of proform and active caspase 3 by enzyme assay, Western blotting and immunocytochemistry. In parallel, a fragment of caspase 3 was cloned for the first time in this species, sequenced and used for in situ hybridization to localize messengers and analysed by a phylogenetic survey to shed light on its homology with reptilian caspases. Results demonstrated that: (1) the follicle cells expressed a caspase of the 3/7 group and the mRNA for caspase 3 was transcribed in the stem phase and was completely translated during cell differentiation; (2) the proform protein was stored during the differentiated (nurse) stage and activated at the end of previtellogenesis provoking the degeneration of cells; (3) the predicted protein sequence, although partial, had a strong similarity with the known reptilian caspases 3. The epithelial cells of the ovarian follicle, therefore, do not employ caspase 3 during the nurse stage but, instead, prepare for apoptosis long before the process actually begins. The relevance of this strategy is discussed. PMID- 27718024 TI - Chronic administration of methionine and/or methionine sulfoxide alters oxidative stress parameters and ALA-D activity in liver and kidney of young rats. AB - High levels of methionine (Met) and methionine sulfoxide (MetO) are found in several genetic abnormalities. Oxidative stress is involved in the pathophysiology of many inborn errors of metabolism. However, little is known about the role of oxidative damage in hepatic and renal changes in hypermethioninemia. We investigated the effect of chronic treatment with Met and/or MetO on oxidative stress parameters in liver and kidney, as lipid peroxidation (TBARS), total sulfhydryl content (SH), reactive oxygen species (ROS) and enzymes activities superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and delta aminolevulinic dehydratase (ALA-D). Serum biochemical parameters were evaluated. Wistar rats were treated daily with two subcutaneous injections of saline (control), Met (0.2-0.4 g/kg), MetO (0.05-0.1 g/kg) and the association between these (Met plus MetO) from the 6th to the 28th day of life. Our data demonstrated an increase of glucose and urea levels in all experimental groups. Cholesterol (MetO and Met plus MetO) were decreased and triglycerides (MetO) were increased. SOD (MetO and Met plus MetO) and CAT (Met, MetO and Met plus MetO) activities were decreased, while GPx was enhanced by MetO and Met plus MetO treatment in liver. In kidney, we observed a reduction of SH levels, SOD and CAT activities and an increase of TBARS levels in all experimental groups. ROS levels in kidney were increased in MetO and Met plus MetO groups. ALA-D activity was enhanced in liver (MetO and Met plus MetO) and kidney (Met plus MetO). These findings help to understand the pathophysiology of hepatic and renal alterations present in hypermethioninemia. PMID- 27718025 TI - In vivo imaging of a cone mosaic in a patient with achromatopsia associated with a GNAT2 variant. AB - PURPOSE: The 2 most common causative genes for achromatopsia (ACHM) are CNGA3 and CNGB3; other genes including GNAT2 account for only a small portion of ACHM cases. The cone mosaics in eyes with CNGA3 and CNGB3 variants are severely disrupted; the cone mosaics in patients with GNAT2-associated ACHM; however, have been reported to show a contiguous pattern in adaptive optics (AO) retinal images. The purpose of this study was to analyze the cone mosaic of another case of GNAT2-associated ACHM. PATIENT AND METHODS: The patient was a 17-year-old Japanese boy. Comprehensive ocular examinations including fundus photography, electroretinography (ERGs), optical coherence tomography (OCT), and whole-exome analysis were performed. The cone mosaic was recorded with a flood-illuminated AO fundus camera, and the cone density was compared with those of 10 normal control eyes. RESULTS: The patient had the typical phenotype of ACHM, and a novel homozygous variant, c.730_743del, in GNAT2 was identified. The fundus did not show any specific abnormalities, and the OCT images showed the presence of the ellipsoid zone. The AO fundus image showed a clearly defined cone mosaic around the fovea. The cone density at 500 MUm from the fovea was reduced by 15-30 % as compared with those of the normal eyes. CONCLUSIONS: This is the first description of a Japanese patient with ACHM with a novel GNAT2 variant. The eyes of this patient had a preserved cone structure with loss of function.

AB - PURPOSE: To determine the effects of vitreomacular separation on macular thickness. METHODS: This was a retrospective, observational, cross-sectional study. Average foveal and central minimum thicknesses were measured by spectral domain optical coherence tomography (SD-OCT) in 308 eyes of 308 healthy subjects (healthy group) and 298 normal fellow eyes of 298 patients with a unilateral macular hole (MH group). Multiple regression analyses were performed to determine the effects of various factors on the macular thickness. RESULTS: The mean age of the healthy group was 67.3 +/- 9.6 years (range 40-88 years) and that of the MH group was 67.8 +/- 7.0 years (range 43-91). SD-OCT images showed that 149 eyes (48.4 %) in the healthy group and 174 eyes (58.4 %) in the MH group had a vitreomacular separation. In the healthy group, the central minimum thickness of eyes with a vitreomacular separation (196 um) was significantly thinner than those without a vitreomacular separation (205 um; P < 0.001). In the MH group, the average foveal thickness (234 um) and the central minimum thickness (177 um) in eyes with a vitreomacular separation were thinner than those without it (247 and 199 um, respectively; both P < 0.001). Multiple regression analyses showed that a vitreomacular separation was significantly correlated with thinner central minimum thicknesses in both groups (P < 0.001) and also with the average foveal thickness in the MH group (P < 0.001). CONCLUSIONS: A vitreomacular separation caused thinning of the central fovea in both the healthy eyes and the normal fellow eyes of unilateral MH patients; the extent of foveal thinning is greater in the MH group. PMID- 27718027 TI - Safety and efficacy of treatment strategies for posterior inferior cerebellar artery aneurysms: a systematic review and meta-analysis. AB - INTRODUCTION: We conducted a systematic review of the literature to evaluate the safety and efficacy of treatment strategies for PICA aneurysms. METHODS: A systematic search of Medline, EMBASE, Scopus, and Web of Science was done for studies published through November 2015. We included studies that described treatment of PICA aneurysms with >=10 patients. Random-effects meta-analysis was used to pool the following outcomes: complete occlusion, technical success, periprocedural morbidity/mortality, stroke rates, aneurysm recurrence/rebleed, CN palsies rates, and long-term neurological morbidity/mortality. RESULTS: We included 29 studies with 796 PICA aneurysms. When considering all ruptured PICA aneurysms, complete occlusion rates were 97.1 % (95 % CI = 94.5-99.0 %) in the surgical group and 84.3 % (95 % CI = 73.8-92.6 %) in the endovascular group. Aneurysm recurrence occurred in 1.4 % (95 % CI = 0.3-3.3 %) after surgery and in 6.9 % (95 % CI = 3.6-10.9 %) after endovascular treatment. Overall neurological morbidity and mortality were 14.4 % (95 % CI = 8.7-21.2 %) and 9.8 % (95 % CI = 5.8-14.8 %) after surgery and 15.1 % (95 % CI = 10.5-20.2 %) and 17.1 % (95 % CI = 11.5-23.7 %) after endovascular treatment, respectively. When considering all unruptured PICA aneurysms, complete occlusion rates were 92.9 % (95 % CI = 79.5 100 %) in the surgical group and 75.7 % (95 % CI = 45.4-97.1 %) in the endovascular group. Overall long-term good neurological outcome rates were 91.5 % (95 % CI = 74.4-100 %) in the surgical series and 93.3 % (95 % CI = 82.7-99.5 %) in the endovascular group. CONCLUSIONS: Our meta-analysis demonstrated that both treatment modalities are technically feasible with high rates of technical success and effective with sufficient long-term aneurysm occlusion rates. Our data suggest that surgery is associated with superior angiographic outcomes. While endovascular therapy could be a reasonable first-line treatment option for proximal PICA aneurysms, surgery remains a highly effective first-line choice for distal PICA aneurysms. These findings should be considered when deciding the best therapeutic strategy. PMID- 27718028 TI - Measuring experimental cyclohexane-water distribution coefficients for the SAMPL5 challenge. AB - Small molecule distribution coefficients between immiscible nonaqueuous and aqueous phases-such as cyclohexane and water-measure the degree to which small molecules prefer one phase over another at a given pH. As distribution coefficients capture both thermodynamic effects (the free energy of transfer between phases) and chemical effects (protonation state and tautomer effects in aqueous solution), they provide an exacting test of the thermodynamic and chemical accuracy of physical models without the long correlation times inherent to the prediction of more complex properties of relevance to drug discovery, such as protein-ligand binding affinities. For the SAMPL5 challenge, we carried out a blind prediction exercise in which participants were tasked with the prediction of distribution coefficients to assess its potential as a new route for the evaluation and systematic improvement of predictive physical models. These measurements are typically performed for octanol-water, but we opted to utilize cyclohexane for the nonpolar phase. Cyclohexane was suggested to avoid issues with the high water content and persistent heterogeneous structure of water saturated octanol phases, since it has greatly reduced water content and a homogeneous liquid structure. Using a modified shake-flask LC-MS/MS protocol, we collected cyclohexane/water distribution coefficients for a set of 53 druglike compounds at pH 7.4. These measurements were used as the basis for the SAMPL5 Distribution Coefficient Challenge, where 18 research groups predicted these measurements before the experimental values reported here were released. In this work, we describe the experimental protocol we utilized for measurement of cyclohexane-water distribution coefficients, report the measured data, propose a new bootstrap-based data analysis procedure to incorporate multiple sources of experimental error, and provide insights to help guide future iterations of this valuable exercise in predictive modeling. PMID- 27718029 TI - Predicting binding poses and affinities for protein - ligand complexes in the 2015 D3R Grand Challenge using a physical model with a statistical parameter estimation. AB - The 2015 D3R Grand Challenge provided an opportunity to test our new model for the binding free energy of small molecules, as well as to assess our protocol to predict binding poses for protein-ligand complexes. Our pose predictions were ranked 3-9 for the HSP90 dataset, depending on the assessment metric. For the MAP4K dataset the ranks are very dispersed and equal to 2-35, depending on the assessment metric, which does not provide any insight into the accuracy of the method. The main success of our pose prediction protocol was the re-scoring stage using the recently developed Convex-PL potential. We make a thorough analysis of our docking predictions made with AutoDock Vina and discuss the effect of the choice of rigid receptor templates, the number of flexible residues in the binding pocket, the binding pocket size, and the benefits of re-scoring. However, the main challenge was to predict experimentally determined binding affinities for two blind test sets. Our affinity prediction model consisted of two terms, a pairwise-additive enthalpy, and a non pairwise-additive entropy. We trained the free parameters of the model with a regularized regression using affinity and structural data from the PDBBind database. Our model performed very well on the training set, however, failed on the two test sets. We explain the drawback and pitfalls of our model, in particular in terms of relative coverage of the test set by the training set and missed dynamical properties from crystal structures, and discuss different routes to improve it. PMID- 27718030 TI - Beyond the Cut Hunter: A Historical Epidemiology of HIV Beginnings in Central Africa. AB - In the absence of direct evidence, an imagined "cut hunter" stands in for the index patient of pandemic HIV/AIDS. During the early years of colonial rule, this explanation goes, a hunter was cut or injured from hunting or butchering a chimpanzee infected with simian immunodeficiency virus, resulting in the first sustained human infection with the virus that would emerge as HIV-1M. We argue here that the "cut hunter" relies on a historical misunderstanding and ecological oversimplification of human-chimpanzee (Pan Troglodytes troglodytes) interactions that facilitated pathogenic transmission. This initial host shift cannot explain the beginnings of the HIV/AIDS pandemic. Instead, we must understand the processes by which the virus became transmissible, possibly between Sangha basin inhabitants and ultimately reached Kinshasa. A historical epidemiology of the late nineteenth and twentieth centuries, provides a much-needed corrective to the major shortcomings of the cut hunter. Based on 62 oral historical interviews conducted in southeastern Cameroon and archival research, we show that HIV emerged from ecological, economic, and socio-political transformations of the late nineteenth and twentieth centuries. The gradual imposition of colonial rule built on and reoriented ecologies and economies, and altered older patterns of mobility and sociality. Certain changes may have contributed to the initial viral host shift, but more importantly, facilitated the adaptation of HIV-1M to human to-human transmission. Our evidence suggests that the most critical changes occurred after 1920. This argument has important implications for public health policy, underscoring recent work emphasizing alternative pathways for zoonotic spillovers into human beings. PMID- 27718031 TI - Influence of Antithrombin on the Regimes of Blood Coagulation: Insights from the Mathematical Model. AB - Blood coagulation is regulated through a complex network of biochemical reactions of blood factors. The main acting enzyme is thrombin whose propagation in blood plasma leads to fibrin clot formation. Spontaneous clot formation is normally controlled through the action of different plasma inhibitors, in particular, through the thrombin binding by antithrombin. In the current study we develop a mathematical model of clot formation both in quiescent plasma and in blood flow and determine the analytical conditions on the antithrombin concentration corresponding to different regimes of blood coagulation. PMID- 27718032 TI - Early Postoperative Intraperitoneal Chemotherapy for Low-Grade Appendiceal Mucinous Neoplasms with Pseudomyxoma Peritonei: Is it Beneficial? AB - BACKGROUND: There is little evidence for the use of early postoperative intraperitoneal chemotherapy (EPIC) in patients with low-grade appendiceal mucinous neoplasms (LAMNs) with pseudomyxoma peritonei (PMP). This study aims to assess the outcomes regarding the use of EPIC in a large cohort of patients with LAMNs with PMP uniformly treated by cytoreductive surgery (CRS) and perioperative intraperitoneal chemotherapy (PIC), all of whom received hyperthermic intraperitoneal chemotherapy (HIPEC), and most of whom also received EPIC. METHODS: This was a retrospective study of prospectively collected data of consecutive patients with peritoneal carcinomatosis of appendiceal origin who underwent CRS and PIC by one surgical team at St George Hospital in Sydney, Australia, between January 1996 and November 2015. Subgroup analyses were performed for patients with a high Peritoneal Cancer Index (PCI) >20 and also based on histopathological subtypes of LAMNs. RESULTS: A total of 250 patients formed the cohort of this study. No significant differences were observed in terms of hospital mortality (p = 0.153), major morbidity rate (i.e., grade III/IV; p = 0.593), intensive care unit stay (p = 0.764), and total hospital stay (p = 0.927); however, patients who received HIPEC + EPIC had a significantly longer stay in the high dependency unit. Multivariate analysis showed combined HIPEC with EPIC is an independent prognostic factor for better survival outcomes (hazard ratio 0.30, 95 % confidence interval 0.12-0.74; p = 0.009), adjusted for age, PCI, and histopathological subtypes. CONCLUSIONS: The combination of HIPEC + EPIC can provide additional survival benefits for patients with LAMNs with PMP compared with HIPEC alone, without increasing postoperative morbidity and mortality. EPIC should be considered following CRS and HIPEC for patients with LAMNs with PMP. PMID- 27718033 TI - Surgeon Volume, Patient Age, and Tumor-Related Factors Influence the Need for Re Excision After Breast-Conserving Surgery. AB - BACKGROUND: Breast-conserving surgery (BCS) is the preferred surgical approach for the majority of patients with early-stage breast cancer. There are frequent issues regarding pathologic margin status, requiring margin re-excision, and, in the literature, there is significant variability in re-excision rates, suggesting this is a potential quality-of-care issue. Understanding the patient-, disease-, and physician-related factors influencing reoperation rates is of importance in an effort to minimize this occurrence. METHODS: A retrospective analysis of all patients referred to our cancer center over a 3-year period (1 January 2011-31 December 2013) was performed. Surgeon volume, and patient- and tumor-related factors were assessed for their impact on re-excision rates. Multivariate logistic regression analysis was performed to identify variables of significance influencing reoperation rates after attempted BCS. RESULTS: Overall, 594 patients underwent initial BCS, with 159 (26.8%) patients requiring at least one re excision to ensure negative pathologic margins. On multivariate analysis, low surgeon case volume, patient age (under 46 years of age), tumor size (>2 cm), and lobular carcinoma were associated with an increased re-excision rate. CONCLUSION: Re-excisions are frequent after BCS and are influenced by surgeon volume, patient age, and tumor-related factors. These factors should be considered when counseling patients considering BCS, and also for quality assurance. PMID- 27718034 TI - Consequences of Violent Victimization for Native American Youth in Early Adulthood. AB - Native American youth are at an elevated risk of violent victimization. And because of their vulnerable position in society, they may also be at risk of experiencing a host of adverse consequences as a result of being victimized. Accordingly, using a subsample of 558 Native American youth and two waves of data from the National Longitudinal Study of Adolescent to Adult Health (49.8 % female; 12-19 years at Wave I; 19-26 years at Wave III), we examined the effects of violent victimization during adolescence on a range of outcomes in early adulthood (poor health, depressive symptoms, suicidality, financial hardship, violent and property offending, alcohol problems, hard drug use, and marijuana use). We also assessed whether youth's attachments to family and to school moderate the effects of victimization on these outcomes. The results showed that adolescent victimization is linked to a small number of outcomes-poor health, depressive symptoms, and violent offending-and that the protective effects of social attachments are not widespread. Specifically, family attachments moderated the effects of victimization on poor health and depressive symptoms, and school attachments moderated the effects of victimization on property offending. These findings suggest that the consequences of victimization and the protective effects of social attachments may differ for Native American youth, and that further quantitative and qualitative research is necessary to understand these patterns. PMID- 27718035 TI - GART mediates the renewal of intestinal epithelial barrier via p38/p53/PUMA cascade in colitis. AB - Glycinamide ribonucleotide formyltransferase (GART) has been established as a pivotal enzyme in de novo purine synthesis, and mediates cellular apoptosis in many diseases. We aimed to investigate the role of GART in the pathogenesis of Crohn's disease (CD). In our study, we demonstrated for the first time that GART expression is up-regulated in patients with active CD and in 2,4,6 trinitrobenzene sulfonic acid (TNBS)-induced acute colitis model. Moreover, the inhibition of GART induced cellular apoptosis and suppressed the migration of IECs through the activation of the MEKK3-MKK3-p38 mitogen-activated protein kinase (MAPK) pathway, following with the dys-regulation of p53 and p53 up regulated modulator of apoptosis (PUMA). Taken together, GART plays a critical role in the protection of cellular apoptosis and migration of intestinal epithelial cells to maintain the integrity of the epithelial barrier, thus providing a new potential approach in designing a novel therapy for CD. PMID- 27718036 TI - "I Am Becoming More and More Like My Eldest Brother!": The Relationship Between Older Siblings, Adolescent Gambling Severity, and the Attenuating Role of Parents in a Large-Scale Nationally Representative Survey Study. AB - The present study examined the association between having older siblings who gamble and adolescent at-risk/problem gambling and how parents (i.e., parental knowledge of their whereabouts) and peers might moderate such effects. Data were drawn from the ESPAD(r)Italia2012 survey (European School Survey Project on Alcohol and Other Drugs) comprising a nationally representative Italian sample of adolescents. The analysis was carried out on a subsample of 10,063 Italian students aged 15-19 years (average age = 17.10; 55 % girls) who had at least one older sibling and who had gambled at some point in their lives. Respondents' problem gambling severity, older gambler sibling, gambler peers, parental knowledge, and socio-demographic characteristics were individually assessed. Multinomial logistic regression analyses including two- and three-way interactions were conducted. The odds of being an at-risk/problem gambler were higher among high school students with older siblings that gambled and those with peers who gambled. Higher parental knowledge (of who the adolescent was with and where they were in their leisure time) was associated with lower rates of at risk/problem gambling. There was also an interaction between gamblers with older siblings and parental knowledge. The combination of having siblings who gambled and a greater level of parental knowledge was associated with lower levels of problem gambling. The present study confirmed the occurrence of social risk processes (older siblings and peers who gambled) and demonstrated that gambling among older siblings and peers represents an important contextual factor for increased at-risk/problem gambling. However, parental knowledge appears to be sufficient to counterbalance the influence of older siblings. PMID- 27718038 TI - Evaluating the role of phase I expansion cohorts in oncologic drug development. AB - Importance Use of expansion cohorts (EC) in phase I trials is increasing. However, the utility of phase I EC in aiding drug development is unclear. We sought to determine factors associated with the inclusion of EC in phase I studies and the impact of EC on subsequent clinical development. Methods We performed a systematic review of all phase I trials published in the Journal of Clinical Oncology between June 2004 and May 2014. Presence of an EC, number of participants, funding source, class of agent, tumor type, and maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) were identified. Subsequent conduct of phase II studies and FDA approval of the study agent was also assessed. Results We identified 252 phase I studies. An EC was included in 105 studies. Average accrual on EC studies was 47 compared to 31 in studies without EC (p < 0.0001). There was no impact of time on the inclusion of EC. Only 4 % of phase I studies with an EC provided sample size justification. Source of funding had the only significant association with inclusion of EC. Addition of a phase I EC did not impact the phase I MTD/RP2D, subsequent phase II trial, or FDA approval. Conclusion The importance of including an EC in phase I trials is subject to ongoing debate. Our results demonstrated little benefit to including EC in phase I studies. These findings support that innovative design strategies are needed to optimize the utility of EC in phase I studies. PMID- 27718037 TI - Finite-Element Modelling of the Acoustic Input Admittance of the Newborn Ear Canal and Middle Ear. AB - Admittance measurement is a promising tool for evaluating the status of the middle ear in newborns. However, the newborn ear is anatomically very different from the adult one, and the acoustic input admittance is different than in adults. To aid in understanding the differences, a finite-element model of the newborn ear canal and middle ear was developed and its behaviour was studied for frequencies up to 2000 Hz. Material properties were taken from previous measurements and estimates. The simulation results were within the range of clinical admittance measurements made in newborns. Sensitivity analyses of the material properties show that in the canal model, the maximum admittance and the frequency at which that maximum admittance occurs are affected mainly by the stiffness parameter; in the middle-ear model, the damping is as important as the stiffness in influencing the maximum admittance magnitude but its effect on the corresponding frequency is negligible. Scaling up the geometries increases the admittance magnitude and shifts the resonances to lower frequencies. The results suggest that admittance measurements can provide more information about the condition of the middle ear when made at multiple frequencies around its resonance. PMID- 27718039 TI - 4-methylumbelliferone and imatinib combination enhances senescence induction in chronic myeloid leukemia cell lines. AB - Chronic myeloid leukemia (CML) is a myeloproliferative syndrome characterized by the presence of the Philadelphia chromosome which encodes a constitutively activated tyrosine kinase (BCR-ABL). The first line treatment for CML consists on BCR-ABL inhibitors such as Imatinib. Nevertheless, such treatment may lead to the selection of resistant cells. Therefore, it is of great value to find molecules that enhance the anti-proliferative effect of first-line drugs. Hyaluronan is the main glycosaminglican of the extracellular matrix which is involved in tumor progression and multidrug resistance. We have previously demonstrated that the inhibition of hyaluronan synthesis by 4-methylumbelliferone (4MU) induces senescence and can revert Vincristine resistance in CML cell lines. However, the effect of 4MU on Imatinib therapy remains unknown. The aim of this work was to determine whether the combination of 4MU with Imatinib is able to modulate the proliferation as well as apoptosis and senescence induction in human CML cell lines. For this purpose the ATCC cell line K562, and its multidrug resistant derivate, Kv562 were used. Cells were exposed to 4MU, Imatinib or a combination of both. We demonstrated that 4MU and Imatinib co-treatment abrogated the proliferation of both cell lines. However, such co-treatment did not increase the levels of apoptosis when compared with the treatment with Imatinib alone. For both cell lines the mechanisms of tumor suppression involved was senescence, since the combination of 4MU and Imatinib arrested the cell cycle and increased senescence associated beta-galactosidase activity and senescence associated heterochromatin foci presence when compared to each drug alone. Moreover, 4MU, Imatinib and 4MU + Imatinib decreased pAkt/Akt ratio in both cell lines and reduced the pERK/ERK ratio only in K562 cells. These findings highlight the potential use of 4MU together with Imatinib for CML therapy. PMID- 27718040 TI - Biogas properties and enzymatic analysis during anaerobic fermentation of Phragmites australis straw and cow dung: influence of nickel chloride supplement. AB - The importance of nickel (added as NiCl2) on mesophilic anaerobic fermentation of Phragmites australis straw and cow dung was demonstrated by investigating the biogas properties, pH values, organic matter degradation [chemical oxygen demand (COD)] and enzyme activities (cellulase, protease and dehydrogenase) during the fermentation process. The results showed that Ni2+ addition increased the cumulative biogas yields by >18 % by improving the efficiency of first peak stage and bringing forward the second peak stage. The pH values were not significantly influenced by Ni2+ addition (p > 0.05). Biogas yields were associated with variations in COD concentrations rather than momentary concentrations. At the start-up stage of fermentation (4th day), the biogas yields increased gradually together with the increase of dehydrogenase activities at elevated Ni2+ concentrations when cellulase and protease activities were similar in all test groups. It is suggested that Ni2+ addition was mainly dependent on the methanogenic stage. After the start-up stage, the impact of Ni2+ addition on biogas production was mainly dependent on its effect on cellulase activities, rather than protease or dehydrogenase activities. PMID- 27718042 TI - Genetic diversity and vector transmission of phytoplasmas associated with sesame phyllody in Iran. AB - During 2010-14 surveys in the major sesame growing areas of Fars, Yazd and Isfahan provinces (Iran), genetic diversity and vector transmission of phytoplasmas associated with sesame phyllody were studied. Virtual RFLP, phylogenetic, and DNA homology analyses of partial 16S ribosomal sequences of phytoplasma strains associated with symptomatic plants revealed the presence of phytoplasmas referable to three ribosomal subgroups, 16SrII-D, 16SrVI-A, and 16SrIX-C. The same analyses using 16S rDNA sequences from sesame phyllody associated phytoplasmas retrieved from GenBank database showed the presence of phytoplasmas clustering with strains in the same subgroups in other Iranian provinces including Bushehr and Khorasan Razavi. Circulifer haematoceps and Orosius albicinctus, known vectors of the disease in Iran, were tested for transmission of the strains identified in this study. C. haematoceps transmitted 16SrII-D, 16SrVI-A, and 16SrIX-C phytoplasmas, while O. albicinctus only transmitted 16SrII-D strains. Based on the results of the present study and considering the reported presence of phytoplasmas belonging to the same ribosomal subgroups in other crops, sesame fields probably play an important role in the epidemiology of other diseases associated with these phytoplasmas in Iran. PMID- 27718041 TI - ITS2 secondary structure for species circumscription: case study in southern African Strychnos L. (Loganiaceae). AB - Recently developed computational tools in ITS2 sequence-structure phylogenetics are improving tree robustness by exploitation of the added information content of the secondary structure. Despite this strength, however, their adoption for species-level clarifications in angiosperms has been slow. We investigate the utility of combining ITS2 sequence and secondary structure to separate species of southern African Strychnos, and assess correlation between compensatory base changes (CBCs) and currently recognised species boundaries. Combined phylogenetic analysis of sequence and secondary structure datasets performed better, in terms of robustness and species resolution, than analysis involving primary sequences only, achieving 100 and 88.2 % taxa discriminations respectively. Further, the Strychnos madagascariensis complex is well-resolved by sequence-structure phylogenetic analysis. The 17 Strychnos species corresponded to 14 ITS2 CBC clades. Four of the five taxa in section Densiflorae belong to a single CBC clade, whose members tend to form natural hybrids. Our finding supports the application of ITS2 as a complementary barcoding marker for species identification. It also highlights the potential of comparative studies of ITS2 CBC features among prospective parental pairs in breeding experiments as a rapid proxy for cross compatibility assessment. This could save valuable time in crop improvement. Patterns of CBC evolution and species boundaries in Strychnos suggests a positive correlation. We conclude that the CBC pattern coupled with observed ITS2 sequence paraphyly in section Densiflorae points to a speciation work-in-progress. PMID- 27718044 TI - The osteoclasts attach to the bone surface where the extracellular calcium concentration decreases. AB - Osteoclasts demineralize and resorb bone once they attach to its surface. However, it's still unclear how the osteoclasts choose the specific sites for their attachments. It is postulated in this article that the decreased extracellular free ionized calcium concentration (Ca2+[e]) can provide a microenvironment for osteoclasts to recognize and then initiate the attachment process. The osteoclasts initially attach to the bone surface via integrating its integrin alphavbeta3 and RGD containing ligands in bone matrix. Through the interaction with RGD-containing ligand, the integrin alphavbeta3 forms carboxylate oxygen noncovalent, which is further stabilized by accompanied electrostatic interaction between the Ca2+ and the beta3 subunit. There are two types of cation-binding sites on the beta3 subunit: the high affinity Ca2+ binding site ("LC" site) that activates the osteoclasts by promoting the combination; the low affinity Ca2+ binding site ("I" site, also named ADMIDAS) that deactivates the osteoclasts by dissociating the combination and it can override the "LC" site's positive effect on osteoclasts when necessary. Normally the Ca2+ concentration of bone extracellular fluid is maintained within a normal range by osteocytes, keeping the "I" sites activated. When the osteocytes' function stalls and the ambient Ca2+ concentration falls below the affinity discrimination threshold between the "I" site and the "LC" site, the "LC" site's promoting function starts to out compete the "I" site in its inhibitory effect, in which case the inactive integrin alphavbeta3 turns into an extended active form and the osteoclasts start to attach, signifying the initiation of bone resorption. PMID- 27718045 TI - Increased Expression of Caspase-12 After Experimental Subarachnoid Hemorrhage. AB - Convincing evidences have proved that apoptosis plays a vital role in the pathogenesis of early and delayed brain injury following subarachnoid hemorrhage (SAH). Recently, a novel caspase-12-mediated apoptotic pathway has been reported to be induced by excess endoplasmic reticulum (ER) stress. Extensive protein damage occurs after SAH, which may trigger ER stress-associated apoptotic pathway. Thus, we hypothesized that caspase-12, as the major molecular marker of this novel apoptotic pathway, may be activated and involved in the pathogenesis of apoptotic injury after SAH. This study sought to investigate the changes of caspase-12 expressions in both in vitro and in vivo SAH models. Western blot analysis found significantly increased protein expressions of both pro- and active forms of caspase-12 after SAH. Quantitative real-time PCR and immunohistochemistry assays confirmed elevated caspase-12 level after SAH in vivo. Further, double immunofluorescence staining revealed obvious caspase-12 over-expression in both cortical neurons and astrocytes. Moreover, immunofluorescent co-staining in vivo demonstrated that neural cells with high immunoreactivity of caspase-12 also expressed caspase-3, and dual immunofluorescent staining for caspase-12 and TUNEL in vitro showed that TUNEL positive cells were more likely to exhibit higher caspase-12 immunoreactivity, indicating a potential contribution of caspase-12 activation to apoptosis in SAH. Collectively, our results showed significant upregulation of caspase-12 expression after experimental SAH. These findings also offer important implications for further investigations of the therapeutic potential of caspase 12 associated apoptosis in SAH. PMID- 27718043 TI - Bacteriophages and its applications: an overview. AB - Bacteriophages (or phages), the most abundant viral entity of the planet, are omni-present in all the ecosystems. On the basis of their unique characteristics and anti-bacterial property, phages are being freshly evaluated taxonomically. Phages replicate inside the host either by lytic or lysogenic mode after infecting and using the cellular machinery of a bacterium. Since their discovery by Twort and d'Herelle in the early 1900s, phage became an important agent for combating pathogenic bacteria in clinical treatments and its related research gained momentum. However, due to recent emergence of bacterial resistance on antibiotics, applications of phage (phage therapy) become an inevitable option of research. Phage particles become popular as a biotechnological tool and treatment of pathogenic bacteria in a range of applied areas. However, there are few concerns over the application of phage-based solutions. This review deals with the updated phage taxonomy (ICTV 2015 Release and subsequent revision) and phage biology and the recent development of its application in the areas of biotechnology, biosensor, therapeutic medicine, food preservation, aquaculture diseases, pollution remediation, and wastewater treatment and issues related with limitations of phage-based remedy. PMID- 27718046 TI - The Role of Ca2+ Imbalance in the Induction of Acute Oxidative Stress and Cytotoxicity in Cultured Rat Cerebellar Granule Cells Challenged with Tetrabromobisphenol A. AB - Using primary cultures of rat cerebellar granule cells (CGC) we examined the role of calcium transients induced by tetrabromobisphenol A (TBBPA) in triggering oxidative stress and cytotoxicity. CGC were exposed for 30 min to 10 or 25 uM TBBPA. Changes in intracellular calcium concentration ([Ca2+]i), in the production of reactive oxygen species (ROS), and in the potential of mitochondria (?Psim) were measured fluorometrically during the exposure. The intracellular glutathione (GSH) and catalase activity were determined after the incubation; cell viability was evaluated 24 h later. TBBPA concentration-dependently increased [Ca2+]i and ROS production, and reduced GSH content, catalase activity, ?Psim and neuronal viability. The combination of NMDA and ryanodine receptor antagonists, MK-801 and bastadin 12 with ryanodine, respectively, prevented Ca2+ transients and partially reduced cytotoxicity induced by TBBPA at both concentrations. The antagonists also completely inhibited oxidative stress and depolarization of mitochondria evoked by 10 uM TBBPA, whereas these effects were only partially reduced in the 25 uM TBBPA treatment. Free radical scavengers prevented TBBPA-induced development of oxidative stress and improved CGC viability without having any effect on the rises in Ca2+ and drop in ?Psim. The co-administration of scavengers with NMDA and ryanodine receptor antagonists provided almost complete neuroprotection. These results indicate that Ca2+ imbalance and oxidative stress both mediate acute toxicity of TBBPA in CGC. At 10 uM TBBPA Ca2+ imbalance is a primary event, inducing oxidative stress, depolarization of mitochondria and cytotoxicity, whilst at a concentration of 25 uM TBBPA an additional Ca2+-independent portion of oxidative stress and cytotoxicity emerges.

AB - Despite intensive vaccination campaigns, outbreaks of Newcastle disease (ND) have been frequently reported in China, especially of genotype VII that first emerged in the late 1990s. Given the dire need for vaccines against the circulating genotype VII virus, we developed an alternative method to recover a highly virulent recombinant GM (rGM) virus that involves a T7 system with a hammerhead ribozyme sequence introduced downstream of the T7 promoter. By changing the F0 polybasic cleavage site RRQKR?F to the monobasic GRQGR?L, we generated a mutant virus (rGM-VIIm) that was found to be highly attenuated in chickens. The rGM-VIIm virus not only produced fourfold higher hemagglutination assay (HA) titers than the parental virus, but also exhibited genetic stability after 15 continuous passages in specific-pathogen-free (SPF) embryonated eggs. Whether live or inactivated, rGM-VIIm and LaSota vaccines can protect vaccinated birds from GM challenge infection. However, live and inactivated rGM-VIIm vaccines reduced virus shedding of the homologous challenge virus significantly better than the LaSota virus vaccine did. Altogether, our results suggest that rGM-VIIm vaccines could aid in the control of ND in China.

AB - Neighborhood socioeconomic status (SES), an overall marker of neighborhood conditions, may determine residents' access to health care, independently of their own individual characteristics. It remains unclear, however, how the distinct settings where individuals seek care vary by neighborhood SES, particularly in US urban areas. With existing literature being relatively old, revealing how these associations might have changed in recent years is also timely in this US health care reform era. Using data on the Philadelphia region from 2002 to 2012, we performed multilevel analysis to examine the associations of neighborhood SES (measured as census tract median household income) with access to usual sources of primary care (physician offices, community health centers, and hospital outpatient clinics). We found no evidence that residence in a low-income (versus high-income) neighborhood was associated with poorer overall access. However, low-income neighborhood residence was associated with less reliance on physician offices [-4.40 percentage points; 95 % confidence intervals (CI) -5.80, -3.00] and greater reliance on the safety net provided by health centers [2.08; 95 % CI 1.42, 2.75] and outpatient clinics [1.61; 95 % CI 0.97, 2.26]. These patterns largely persisted over the 10 years investigated. These findings suggest that safety-net providers have continued to play an important role in ensuring access to primary care in urban, low-income communities, further underscoring the importance of supporting a strong safety net to ensure equitable access to care regardless of place of residence. PMID- 27718049 TI - Diagnosis of early colorectal cancer invasion depth by quantitative evaluation of the basal indentation in CT colonography. AB - OBJECTIVE: To investigate the feasibility of diagnosing the invasion depth of early colorectal cancer (CRC) by quantitatively evaluating the basal indentation (BI)-i.e., the intestinal lateral deformity-in CT colonography (CTC). MATERIALS AND METHODS: 34 early CRCs (13 Tis CRCs and 21 T1 CRCs) in 32 patients who underwent a preoperative CTC were retrospectively examined. Two radiologists calculated the depth of the BI on a computed tomographic air-contrast enema (CT enema) image, the depth of the BI due to the geometric function (BI-G) on a cross sectional multiplanar reconstruction (CS-MPR) image, and the ratio of the BI to the BI-G (i.e., the "BI ratio") for each lesion. The BI ratios of the Tis and T1 CRCs were compared. RESULTS: The BI ratios were significantly higher in the T1 CRCs than in the Tis CRCs (p < 0.0001). The optimum cutoff value of the BI ratio for differentiating the T1 CRCs from the Tis CRCs was 1.64, with a sensitivity, specificity, and area under the curve of 90.5 %, 100 %, and 0.974, respectively. CONCLUSIONS: We have demonstrated for the first time that quantitatively evaluating the BI can improve the accuracy of diagnosis of early CRC invasion depth.

AB - INTRODUCTION: Limited data are available on the impact of hypertension in the different regions or urban areas in Italy. AIM: To evaluate hypertension prevalence and control among adult outpatients followed by general practitioners (GPs) in different regions and macro-areas in our Country. METHODS: We retrospectively analysed data extracted in 2013 from the national GP Health Search-CSD database and stratified into three groups, depending on their own regions (North, Center and South). Hypertension prevalence was estimated within the overall population sample of adult individuals, whereas control was assessed in hypertensive outpatients. Hypertension diagnosis was defined according to International Classification of Diseases 9. Clinic blood pressure (BP) levels were measured according to European guidelines. BP control was defined as BP <140/90 mmHg. RESULTS: Data from 940,806 individuals (52.0 % female) were scrutinized, among whom 363,324 (38.6 %) subjects were residents in the North, 276,643 (29.4 %) in the Center and 300,839 (32.0 %) in the South. Overall hypertension prevalence was higher in North (36.8 %) compared to South (33.8 %) and Center (29.3 %). Controlled BP levels were more frequently registered in the South (66.3 %) compared to Center (60.7 %) and North (55.6 %). In all these areas, prevalence and control of hypertension were higher in female than in male individuals. CONCLUSIONS: The present analysis demonstrates relevant differences in hypertension prevalence and control among different macro-areas and regions in Italy. Such analysis may be useful for promoting strategies aimed at ameliorating hypertension control at local levels. PMID- 27718053 TI - ? PMID- 27718052 TI - [Reliability and construct validity of the OPD-CA axes: structure and prerequisites for treatment]. AB - BACKGROUND: The aim of this study was to compare the Operationalized Psychodynamic Diagnostics (OPD-CA) for children and adolescents with the modified version (OPD-CA-2) focusing on the mainly unchanged treatment conditions and the redesigned structure axis. METHODS: The patient sample consisted 371 inpatient children and adolescents with psychiatric disorders from 3 to 18 years. OPD-CA and OPD-CA-2 diagnostics were routinely performed by OPD-experienced raters. Statistical calculation included Cronbach's alpha (internal consistency) and confirmatory factor analysis. RESULTS: The OPD-CA-2 structure axis showed very good internal consistency (reliability) compared to the OPD-CA. We found satisfactorily good values for the treatment conditions with slightly higher average scores in the OPD-CA-2. Confirmatory factor analysis resulted in two models where the items on the OPD-CA-2 structure axis were stronger correlated than those of the OPD-CA. CONCLUSION: The OPD-CA-2 is a reliable and valid instrument for assessing treatment conditions and psychic structure in children and adolescents. The reorganization of the structure axis and the treatment conditions in the OPD-CA-2 resulted in a measurable improvement.

AB - Histamine is a pro-inflammatory mediator with a prominent role in allergic diseases. Antagonists at the histamine receptor subtype 1 are central in anti allergic therapies, with the exception of allergic asthma, where they are clinically without effect. The latest identified histamine receptor subtype 4, which is expressed mainly in hematopoietic cells, now provides a reasonable target for new therapeutic strategies inhibiting histamine function. The pathophysiology of allergy, esp. allergic asthma, and in its context the effects of antagonists at the histamine receptor subtype 4 in preclinical and clinical settings are discussed in this chapter. PMID- 27718055 TI - In reply: Anesthesia scavenging in critical care areas: beware of possible hazards and questionable efficacy. PMID- 27718057 TI - Delta Opioid Pharmacology in Parkinson's Disease. AB - Parkinson's disease (PD) is a progressive neurodegenerative disorder that compromises multiple neurochemical substrates including dopamine, norepinephrine, serotonin, acetylcholine, and glutamate systems. Loss of these transmitter systems initiates a cascade of neurological deficits beginning with motor function and ending with dementia. Current therapies primarily address the motor symptoms of the disease via dopamine replacement therapy. Exogenous dopamine replacement brings about additional challenges since after years of treatment it almost invariably gives rise to dyskinesia as a side effect. Therefore there is a clear unmet clinical need for improved PD therapeutics. Opioid receptors and their respective peptides are expressed throughout the basal ganglia and cortex where monoaminergic denervation strongly contributes to PD pathology. Delta opioid receptors are of particular interest because of their dense localization in basal ganglia and because activating this system is known to enhance locomotor activity under a variety of conditions. This chapter will outline much of the work that has demonstrated the effectiveness of delta opioid receptor activation in models of PD and its neuroprotective properties. It also discusses some of the challenges that must be addressed before moving delta opioid receptor agonists into a clinical setting. PMID- 27718058 TI - Mitochondrial Changes in Cancer. AB - Mitochondrial structural and functional integrity defines the health of a cell by regulating cellular metabolism. Thus, mitochondria play an important role in both cell proliferation and cell death. Cancer cells are metabolically altered compared to normal cells for their ability to survive better and proliferate faster. Resistance to apoptosis is an important characteristic of cancer cells and given the contribution of mitochondria to apoptosis, it is imperative that mitochondria could behave differently in a tumor situation. The other feature associated with cancer cells is the Warburg effect, which engages a shift in metabolism. Although the Warburg effect often occurs in conjunction with dysfunctional mitochondria, the relationship between mitochondria, the Warburg effect, and cancer cell metabolism is not clearly decoded. Other than these changes, several mitochondrial gene mutations occur in cancer cells, mitochondrial biogenesis is affected and mitochondria see structural and functional variations. In cancer pharmacology, targeting mitochondria and mitochondria associated signaling pathways to reduce tumor proliferation is a growing field of interest. This chapter summarizes various changes in mitochondria in relevance to cancer, behavior of mitochondria during tumorigenesis, and the progress on using mitochondria as a therapeutic target for cancer. PMID- 27718060 TI - Platelet-Derived Growth Factor in Heart Failure. AB - Defective vascular and cardiomyocyte function are implicated in the development and progression of both heart failure with reduced and preserved ejection fraction. Any treatment option that augments these myocardial processes may therefore be of significant value. The platelet-derived growth factor (PDGF) family is involved in a wide range of growth processes and plays a key role in both regulating angiogenesis and mesenchymal cell development. Thus, PDGF may serve as a potent therapy for heart failure. While numerous animal studies have demonstrated beneficial cardiovascular effects of growth factor therapy, promising laboratory data has not yet translated to effective therapies. In this review, we outline the biological role of PDGF and summarize previous studies that have focused on the cardiovascular effects of normal PDGF signaling, administration of PDGF, and the effects of PDGF on stem cell therapy. PMID- 27718059 TI - Epidemiology of Heart Failure. AB - Heart failure (HF) is a major public health problem affecting more than 23 million patients worldwide. Incidence and prevalence rates vary significantly according to the source of data, but both increase with advancing age reaching, in the very elderly, prevalence rates that represent a challenge for the organization of medical care systems. Even if evidence-based treatments have improved prognosis in some patients with HF, patients with HF still need to be carefully characterized, described, and treated. Hospitalizations for acute HF are frequent and costly accounting for the vast majority of HF-related costs. PMID- 27718061 TI - Society of behavioral medicine supports increasing HPV vaccination uptake: an urgent opportunity for cancer prevention. AB - Human papillomavirus (HPV) vaccine coverage remains low in the USA. The Society for Behavioral Medicine (SBM) supports the goals outlined by Healthy People 2020, the President's Cancer Panel, and the National Vaccine Advisory Committee to increase vaccination coverage among both males and females. SBM makes the following recommendations in support of efforts to reduce structural and other barriers to HPV vaccination services in order to increase rates of series completion. We encourage legislators and other policymakers to improve administration authority, insurance coverage, and reimbursement rates to healthcare providers who make the HPV vaccine available to adolescents; provide instrumental support to fund the development of school curricula on HPV vaccination; and increase public awareness that HPV vaccination can prevent cancer. We urge healthcare providers and healthcare systems to increase the strength, quality, and consistency of HPV vaccination recommendations for all eligible patients; to treat HPV vaccination as a routine preventive service; employ culturally appropriate communication strategies in clinical settings to educate eligible patients, parents, and guardians about the importance, effectiveness, and safety of HPV vaccination; and to strengthen and better coordinate the use of electronic medical records and immunization information systems. PMID- 27718062 TI - Predictors of and health- and fall-related program outcomes resulting from complete and adequate doses of a fall risk reduction program. AB - Falls are dangerous and costly for older adults. The A Matter of Balance/Volunteer Lay Leader (AMOB/VLL) program is an evidence-based fall risk reduction program that could help reduce this burden. This study introduced a door-through-door transportation program to improve program delivery (N = 126). Characteristics predicting completion of all eight AMOB/VLL sessions were identified using logistic regression. Individual growth models were employed to determine the immediate, intermediate, and long-term goal outcomes resulting from receiving an adequate dose of the program (five to eight sessions). Self restriction of activities due to fear of falling (OR 5.04, 95 % CI 1.86-13.69) and a lower frequency of moderate and vigorous physical activity (OR 1.14, 95 % CI 1.04-1.27) were significantly predictive of receiving a complete dose. Three outcome goals were significant, including (1) immediate-improved self-efficacy of managing medications and treatments, (2) intermediate-reduced activity limitations, and (3) intermediate-reduced physical disability. Self-restriction of activities due to a fear of falling and physical activity levels may be simple and effective screening questions to prevent AMOB/VLL attrition. In our study, those who did receive the program improved on a specific type of self-efficacy and on self-reported physical functioning. PMID- 27718063 TI - Strategies of chemical anti-predator defences in leaf beetles: is sequestration of plant toxins less costly than de novo synthesis? AB - The evolution of defensive traits is driven both by benefits gained from protection against enemies and by costs of defence production. We tested the hypothesis that specialisation of herbivores on toxic host plants, accompanied by the ability to acquire plant defensive compounds for herbivore defence, is favoured by the lower costs of sequestration compared to de novo synthesis of defensive compounds. We measured physiological costs of chemical defence as a reduction in larval performance in response to repeated removal of secretions (simulating predator attack) and compared these costs between five species synthesising defences de novo and three species sequestering salicylic glucosides (SGs) from their host plants. Experiments simulating low predator pressure revealed no physiological costs in terms of survival, weight and duration of development in any of study species. However, simulation of high predation caused reduction in relative growth rate in Chrysomela lapponica larvae producing autogenous defences more frequently, than in larvae sequestering SGs. Still meta analysis of combined data showed no overall difference in costs of autogenous and sequestered defences. However, larvae synthesising their defences de novo demonstrated secretion-conserving behaviour, produced smaller amounts of secretions, replenished them at considerably lower rates and employed other types of defences (regurgitation, evasion) more frequently when compared to sequestering larvae. These latter results provide indirect evidence for biosynthetic constraints for amounts of defensive secretions produced de novo, resulting in low defence effectiveness. Lifting these constraints by sequestration may have driven some leaf beetle lineages toward sequestration of plant allelochemicals as the main defensive strategy. PMID- 27718064 TI - Enhanced leaf nitrogen status stabilizes omnivore population density. AB - Plant traits can mediate the strength of interactions between omnivorous predators and their prey through density effects and changes in the omnivores' trophic behavior. In this study, we explored the established assumption that enhanced nutrient status in host plants strengthens the buffering effect of plant feeding for omnivorous predators, i.e., prevents rapid negative population growth during prey density decline and thereby increases and stabilizes omnivore population density. We analyzed 13 years of field data on population densities of a heteropteran omnivore on Salix cinerea stands, arranged along a measured leaf nitrogen gradient and found a 195 % increase in omnivore population density and a 63 % decrease in population variability with an increase in leaf nitrogen status from 26 to 40 mgN * g-1. We recreated the leaf nitrogen gradient in a greenhouse experiment and found, as expected, that increasing leaf nitrogen status enhanced omnivore performance but reduced per capita prey consumption. Feeding on high nitrogen status host plants can potentially decouple omnivore-prey population dynamics and allow omnivores to persist and function effectively at low prey densities to provide "background level" control of insect herbivores. This long term effect is expected to outweigh the short-term effect on per capita prey consumption-resulting in a net increase in population predation rates with increasing leaf nitrogen status. Conservation biological control of insect pests that makes use of omnivore background control could, as a result, be manipulated via management of crop nitrogen status. PMID- 27718066 TI - Joint effects of resources and amphibians on pond ecosystems. AB - Primary production can be controlled through bottom-up (e.g., resources) or top down (e.g., predators) constraints. Two key bottom-up resources in small aquatic systems are light and nutrients, and forest canopy cover heavily influences these factors, whereas amphibian and invertebrate colonizers exert top-down pressure as grazers and predators. We designed our experiment to specifically manipulate two different top-down and bottom-up factors. We manipulated resources by altering light (low/high) and nutrient (low/high) availability; omnivores with the presence/absence of southern leopard frog tadpoles (Lithobates sphenocephalus); and predators with the presence/absence of spotted salamander larvae (Ambystoma maculatum) in a full-factorial experiment conducted over 14 weeks. We observed that both bottom-up and top-down effects were important in predicting lower trophic level biomass. We found a significant top-down effect of salamanders on Daphnia, but tadpoles had the strongest overall effect on the food web, influencing phytoplankton (+), periphyton (-), and chironomids (-). None of our models were good predictors of phytoplankton biomass, but both shading and nutrient availability relatively equally boosted periphyton biomass. We also found large temporal differences in food-web dynamics. Our results underscore the need for more information into how ecosystem functioning could be altered by land use, amphibian extirpation, and climate change. PMID- 27718065 TI - Seasonal fecundity is not related to geographic position across a species' global range despite a central peak in abundance. AB - The range of a species is determined by the balance of its demographic rates across space. Population growth rates are widely hypothesized to be greatest at the geographic center of the species range, but indirect empirical support for this pattern using abundance as a proxy has been mixed, and demographic rates are rarely quantified on a large spatial scale. Therefore, the texture of how demographic rates of a species vary over its range remains an open question. We quantified seasonal fecundity of populations spanning the majority of the global range of a single species, the saltmarsh sparrow (Ammodramus caudacutus), which demonstrates a peak of abundance at the geographic center of its range. We used a novel, population projection method to estimate seasonal fecundity inclusive of seasonal and spatial variation in life history traits that contribute to seasonal fecundity. We replicated our study over 3 years, and compared seasonal fecundity to latitude and distance among plots. We observed large-scale patterns in some life history traits that contribute to seasonal fecundity, such as an increase in clutch size with latitude. However, we observed no relationship between latitude and seasonal fecundity. Instead, fecundity varied greatly among plots separated by as little as 1 km. Our results do not support the hypothesis that demographic rates are highest at the geographic and abundance center of a species range, but rather they suggest that local drivers strongly influence saltmarsh sparrow fecundity across their global range. PMID- 27718067 TI - Dermatologic events from EGFR inhibitors: the issue of the missing patient voice. AB - PURPOSE: As epidermal growth factor receptor (EGFR) inhibitors are associated with a variety of dermatologic adverse events (dAEs), the purpose of this study was to develop an overview of current knowledge of dAEs associated with EGFR inhibitors and to identify knowledge gaps regarding incidence, treatment, impact on quality of life (QOL), and patient acceptance. METHOD: A structured literature search was conducted using MEDLINE/PubMed (January 1983 to January 2014). In total, 71 publications published from 2004 to 2014 were identified for consideration in the final evidence review. RESULTS: The majority of published articles concentrate on the incidence of skin reactions, duration, treatment, and prevention strategies. Different grading systems based on the symptoms of skin rash or on health-related QOL (HRQOL) are used. An additional topic is the possible correlation between acneiform rash and efficacy of EGFR inhibitors. Knowledge gaps identified in the literature were how dAEs impact QOL compared with other AEs from a patient's perspective, patients' acceptance of dAEs (willingness to tolerate), and the impact of physician-patient communication on treatment decisions. CONCLUSIONS: Research is needed on the impact of dAEs on patients' acceptance of cancer treatments. Systematic studies are missing that compare the impact of dAEs with other toxicities on therapy decisions from both physician's and patient's view, and that investigate the balance between efficacy and avoidance of acneiform rash in treatment decisions. Such studies could provide deeper insights into the acceptance of the risk of untoward dermatologic events by both physicians and patients when treating advanced cancers. PMID- 27718068 TI - Advance directives in patients with advanced cancer receiving active treatment: attitudes, prevalence, and barriers. AB - PURPOSE: The purposes of the study were to assess awareness and prevalence of advance directives (ADs) among patients with advanced cancer undergoing active outpatient care and to determine factors associated with AD completion before and after the diagnosis of cancer. METHODS: Patients with advanced solid tumor malignancy receiving treatment at the Chemotherapy Day Unit were approached for recruitment. They completed an onsite questionnaire about completion and timing of ADs, demographic information, and perceived health; a review of their medical records was conducted to document their cancer care and co-morbidities. Multinomial logistic regression analysis identified factors associated with the timing of AD completion (pre-cancer, post-cancer, or not at all). RESULTS: Two hundred patients were enrolled, with 193 surveys available for analysis. ADs were completed in 55 % (106/193) of patients, including a living will in 33 % (63/193), a power of attorney in 49 % (95/193), and a do-not-resuscitate (DNR) designation in 18 % (35/193). Most patients (53 %) had completed an AD before being diagnosed with cancer. Higher income (p = 0.02) and age (p = 0.004) were associated with AD completion pre-cancer diagnosis; discussion of end-of-life care (p = 0.02) and palliative care referral (p < 0.0001) were associated with AD completion post-cancer diagnosis. CONCLUSIONS: This study demonstrates that different factors may influence the completion of ADs before and after a diagnosis of cancer and highlights the potential for early palliative care to impact the completion of ADs in patients with advanced cancer who are undergoing active cancer treatment. PMID- 27718069 TI - Comparative analysis of bleeding risk by the location and shape of arachnoid cysts: a finite element model analysis. AB - OBJECTIVE: Although arachnoid cysts (ACs) are observed in various locations, only sylvian ACs are mainly regarded to be associated with bleeding. The reason for this selective association of sylvian ACs with bleeding is not understood well. This study is to investigate the effect of the location and shape of ACs on the risk of bleeding. METHODS: A developed finite element model of the head/brain was modified for models of sylvian, suprasellar, and posterior fossa ACs. A spherical AC was placed at each location to compare the effect of AC location. Bowl-shaped and oval-shaped AC models were developed to compare the effect by shape. The shear force on the spot-weld elements (SFSW) was measured between the dura and the outer wall of the ACs or the comparable arachnoid membrane in the normal model. RESULTS: All AC models revealed higher SFSW than comparable normal models. By location, sylvian AC displayed the highest SFSW for frontal and lateral impacts. By shape, small outer wall AC models showed higher SFSW than large wall models in sylvian area and lower SFSW than large ones in posterior fossa. In regression analysis, the presence of AC was the only independent risk of bleeding. CONCLUSION: The bleeding mechanism of ACs is very complex, and the risk quantification failed to show a significant role of location and shape of ACs. The presence of AC increases shear force on impact condition and may be a risk factor of bleeding, and sylvian location of AC may not have additive risks of AC bleeding. PMID- 27718070 TI - Neurological assessment of Chinese infants with positional plagiocephaly using a Chinese version of the Infant Neurological International Battery (INFANIB). AB - PURPOSE: Positional plagiocephaly (PP) is the most common subtype of asymmetric deformity in the infant skull. Cumulative evidence has demonstrated that PP is associated with abnormal neuromotor development; however, neurological assessment scores of infants with PP have not been well established, and PP has not attracted sufficient attention in China. This study used a Chinese version of the Infant Neurological International Battery (INFANIB) to identify neurological abnormalities among infants with PP and to determine the differences between infants with different (mild, moderate, and severe) degrees of PP. METHODS: We compared the neurological evaluation scores between 393 infants with different degrees of PP and 390 healthy infants from 0 to 18 months of age using a Chinese version of the INFANIB. RESULTS: The infants with PP aged 0-7.9 months had lower scores on the spasticity, head and trunk, leg, and French angle subscales and lower total scores than the normal infants. Additionally, the infants with PP aged 9-18 months showed statistically significantly lower scores on the spasticity, head and trunk, vestibular function, leg, and French angle subscales and total scores than the normal infants. Among the PP subgroups, the infants with mild PP had the highest scores, followed by the infants with moderate PP and the infants with severe PP. Compared with the normal infants, the infants with PP had abnormal neurological assessment scores, and the degree of neurological abnormality was associated with the severity of PP. CONCLUSIONS: The INFANIB revealed neurological abnormalities, including asymmetric movements and abnormal muscle tone, postures, and reflexes, in infants with PP, especially those with moderate or severe PP. These abnormalities were similar to those of infants with cerebral palsy. Therefore, PP may serve as a marker of neurodevelopmental risk and should receive considerable attention. Whether moderate or severe PP is related to cerebral palsy remains to be confirmed in long-term follow-up studies and other future studies. PMID- 27718071 TI - The efficacy of fidaxomicin in the treatment of Clostridium difficile infection in a real-world clinical setting: a Spanish multi-centre retrospective cohort. AB - The objective of this study was to evaluate the efficacy and safety of fidaxomicin in the real-life clinical setting. This was a retrospective cohort of patients with Clostridium difficile infection (CDI) treated with fidaxomicin in 20 Spanish hospitals between July 2013 and July 2014. Clinical cure, 30-day recurrence, 30-day mortality, sustained cure, and factors associated with the failure to achieve sustained cure were analyzed. Of the 72 patients in the cohort 41 (56.9 %) had a fatal underlying disease. There were 44 (61.1 %) recurrent episodes and 26 cases (36.1 %) with a history of multiple recurrences. Most episodes were severe (26, 36 %) or severe-complicated (14, 19.4 %). Clinical cure rate was 90.3 %, recurrence rate was 16.7 % and three patients (4.2 %) died during the follow-up period. Sustained cure was achieved in 52 cases (72.2 %). Adverse events were reported in five cases (6.9 %). Factors associated with the lack of sustained cure were cardiovascular comorbidity (OR 11.4; 95 %CI 1.9 67.8), acute kidney failure (OR 7.4; 95 %CI 1.3-43.1), concomitant systemic antibiotic treatment (OR 6.2; 95 %CI 1.1-36.8), and C-reactive protein value at diagnosis (OR 1.2 for each 1 mg/dl increase; 95 %CI 1.03-1.3). Fidaxomicin is an effective and well tolerable treatment for severe CDI and for cases with elevated recurrence risk. PMID- 27718073 TI - Whole-genome characterisation of G12P[6] rotavirus strains possessing two distinct genotype constellations co-circulating in Blantyre, Malawi, 2008. AB - Rotavirus A strains detected in diarrhoeal children commonly possess any one of the genotypes G1, G2, G3, G4, and G9, with a recent increase in G12 detection globally. G12P[6] strains possessing short RNA (DS-1-like) and long RNA (Wa-like) migration patterns accounted for 27 % of the strains circulating in Blantyre, Malawi, between 2007 and 2008. To understand how the G12P[6] strains with two distinct genetic backgrounds emerged in Malawi, we conducted whole-genome analysis of two long-RNA and two short-RNA strains. While the former had a typical Wa-like genotype constellation of G12-P[6]-I1-R1-C1-M1-A1-N1-T1-E1-H1, the latter was found to have G12-P[6]-I2-R2-C2-M1-A2-N2-T2-E2-H2: a VP3 gene mono reassortant on the DS-1-like backbone. Phylogenetic and Bayesian Markov chain Monte Carlo analyses showed that the short-RNA G12P[6] strains were generated around 2006 by reassortment between an African Wa-like G12P[6] strain donating three genes (the VP7, VP4, and VP3 genes) and a G2P[4] strain similar to the one circulating in Thailand or the United States of America that donated the remaining eight genes. On the other hand, the long-RNA strains were generated as a result of reassortment events within Wa-like G12 and non-G12 strains commonly circulating in Africa; only the VP4 gene was from a Malawian G8P[6] strain. In conclusion, this study uncovered the evolutionary pathways through which two distinct G12P[6] strains emerged in Malawi. PMID- 27718072 TI - Acrolein-detoxifying isozymes of glutathione transferase in plants. AB - MAIN CONCLUSION: Acrolein is a lipid-derived highly reactive aldehyde, mediating oxidative signal and damage in plants. We found acrolein-scavenging glutathione transferase activity in plants and purified a low K M isozyme from spinach. Various environmental stressors on plants cause the generation of acrolein, a highly toxic aldehyde produced from lipid peroxides, via the promotion of the formation of reactive oxygen species, which oxidize membrane lipids. In mammals, acrolein is scavenged by glutathione transferase (GST; EC 2.5.1.18) isozymes of Alpha, Pi, and Mu classes, but plants lack these GST classes. We detected the acrolein-scavenging GST activity in four species of plants, and purified an isozyme showing this activity from spinach (Spinacia oleracea L.) leaves. The isozyme (GST-Acr), obtained after an affinity chromatography and two ion exchange chromatography steps, showed the K M value for acrolein 93 MUM, the smallest value known for acrolein-detoxifying enzymes in plants. Peptide sequence homology search revealed that GST-Acr belongs to the GST Tau, a plant-specific class. The Arabidopsis thaliana GST Tau19, which has the closest sequence similar to spinach GST-Acr, also showed a high catalytic efficiency for acrolein. These results suggest that GST plays as a scavenger for acrolein in plants. PMID- 27718074 TI - Characterization of hepatitis B virus infection in illicit drug users in the Marajo Archipelago, northern Brazil. AB - South America is considered to have a low prevalence of hepatitis B virus (HBV) infection, although areas with a relatively high prevalence have been identified in northern Brazil. Few epidemiological studies of populations at risk of HBV infection are available for this region. Given this, in the present study, we investigated the prevalence of HBV and the factors associated with infection among illicit drug users (DUs) in the Marajo Archipelago, northern Brazil. In this cross-sectional study, we collected samples and epidemiological information from DUs in 11 municipalities of the Marajo Archipelago. The diagnosis was established by ELISA and real-time PCR; and genotyping was done by multiplex real time PCR. Statistical modeling was based on simple and multiple logistical regressions with the Hosmer-Lemeshow test. The mean age of the 466 DUs was 28.4 years, and most were male. The most-consumed illicit drugs were crack cocaine and marijuana. In all, 171 DUs were exposed to HBV, with genotypes A, D and F being identified. The factors associated with higher frequencies of HBV infection were (i) male gender, (ii) age above 35 years, (iii) anti-HIV positivity, (iv) tattoos, (v) the use of injected drugs, (vi) the use of illicit drugs for more than 3 years, (vii) sexual relations without protection, (viii) sexual relations with another DU, and (ix) more than 10 sexual partners in the past 24 months. In summary, this study provides important insights into the dynamics of HBV infection among DUs in the Marajo Archipelago. We hope that these findings will contribute to the development of strategies, actions and public health policies aimed at preventing and controlling this viral infection more effectively. PMID- 27718076 TI - Site of metastasis and breast cancer mortality: a Danish nationwide registry based cohort study. AB - Survival among patients with metastatic breast cancer may vary according to the site of metastasis and receptor status. We used Danish nationwide medical registries to establish a cohort of patients with metastatic breast cancer (870 with de novo metastatic disease and 3518 with recurrent disease with distant metastasis) diagnosed during 1997-2011. We examined 1-year and >1 to 5-year mortality associated with first site of metastasis and receptor expression status of the primary tumor. Cox proportional regression was used to compute confounder adjusted mortality rate ratios (MRRs) associated with site of metastasis, stratified by receptor status. Overall 1-year and >1 to 5-year mortality risks were 36 and 69 %, respectively. Risk of death within 1 year was highest for brain only (62 %) and liver-only (43 %) involvement and nearly the same for patients with lung-only (32 %), bone-only (32 %) involvement, and other/combination of sites (34 %). Using bone-only metastasis as reference, women with brain-only metastasis had more than two-fold increased risk of dying. The adjusted MRR for women with liver-only metastasis also was increased, though less pronounced. Patients with lung-only [adjusted MRR 0.9 (95 % confidence interval (CI) 0.8, 1.1)] or other metastases [adjusted MRR 1.0 (95 % CI 0.9, 1.2)] had similar mortality as patients with bone-only metastasis. Positive hormonal receptor status was a favorable prognostic factor. Metastatic breast cancer has a serious prognosis. Patients with brain-only metastasis had the highest mortality. Positive hormonal receptor status on the primary tumor was a favorable prognostic factor for all metastatic sites. PMID- 27718075 TI - The prevalence and genotype distribution of rotavirus A infection among children with acute gastroenteritis in Kunming, China. AB - The aim of this study was to determine the prevalence of rotavirus A (RVA) infections in children from Kunming, China, and the RVA genotypes present. A total of 16,311 children with acute gastroenteritis were recruited for the study, and 33.1 % (5,394/16,311) were RVA positive. Children under 24 months of age were more susceptible to RVA infection, with an infection rate of 87.4 % (4,712/5,394). The most prevalent genotype was G9P[8] (85/107, 79.4 %), which showed high sequence similarity to G9P[8] strains from other regions of China and neighbouring countries, but not to the licensed vaccine strain LLR. These findings should be useful for the prevention of RVA infections. PMID- 27718077 TI - A theoretical analysis of substituent electronic effects on phosphine-borane bonds. AB - Phosphine-borane adducts are a well-known moiety in synthetic and coordination chemistry. These complexes form a dative bond in which the Lewis basic phosphorus atom donates electron density into an empty p-orbital of the Lewis acidic boron atom. However, donation of the phosphorus lone pair is not the only stabilizing interaction, as hyperconjugation and electrostatic interaction also play important roles in bonding. This paper describes a detailed density functional theory level (B3LYP) study completed to determine the impact electron-donating and withdrawing substituents have on phosphine-borane bonds through the investigation of a series of para-substituted PAr3-BH3 and PH3-BAr3 phosphine borane adducts. Natural bond orbital (NBO) partitioning was used to calculate the distribution of electron density between the phosphine and borane fragments. Extended transition state and natural orbitals for chemical valence (ETS-NOCV) analysis was used to isolate contributions to the overall electronic interaction of the phosphine-borane adducts. Molecular orbital composition and charge donation was calculated using AOMix. The resulting data was correlated with Hammett sigma constants. PMID- 27718078 TI - Interleaving cerebral CT perfusion with neck CT angiography part I. Proof of concept and accuracy of cerebral perfusion values. AB - OBJECTIVES: We present a novel One-Step-Stroke protocol for wide-detector CT scanners that interleaves cerebral CTP with volumetric neck CTA (vCTA). We evaluate whether the resulting time gap in CTP affects the accuracy of CTP values. METHODS: Cerebral CTP maps were retrospectively obtained from 20 patients with suspicion of acute ischemic stroke and served as the reference standard. To simulate a 4 s gap for interleaving CTP with vCTA, we eliminated one acquisition at various time points of CTP starting from the bolus-arrival-time(BAT). Optimal timing of the vCTA was evaluated. At the time point with least errors, we evaluated elimination of a second time point (6 s gap). RESULTS: Mean absolute percentage errors of all perfusion values remained below 10 % in all patients when eliminating any one time point in the CTP sequence starting from the BAT. Acquiring the vCTA 2 s after reaching a threshold of 70HU resulted in the lowest errors (mean <3.0 %). Eliminating a second time point still resulted in mean errors <3.5 %. CBF/CBV showed no significant differences in perfusion values except MTT. However, the percentage errors were always below 10 % compared to the original protocol. CONCLUSION: Interleaving cerebral CTP with neck CTA is feasible with minor effects on the perfusion values. KEY POINTS: * Removing a single CTP acquisition has minor effects on calculated perfusion values * Calculated perfusion values errors depend on timing of skipping a CTP acquisition * Qualitative evaluation of CTP was not influenced by removing two time points * Neck CTA is optimally timed in the upslope of arterial enhancement. PMID- 27718080 TI - Prospective validation of the ultrasound based TIRADS (Thyroid Imaging Reporting And Data System) classification: results in surgically resected thyroid nodules. AB - OBJECTIVE: To assess performance of TIRADS classification on a prospective surgical cohort, demonstrating its clinical usefulness. METHODS: Between June 2009 and October 2012, patients assessed with pre-operative ultrasound (US) were included in this IRB-approved study. Nodules were categorised according to our previously described TIRADS classification. Final pathological diagnosis was obtained from the thyroidectomy specimen. Sensitivity, specificity, positive/negative predictive values and likelihood ratios were calculated. RESULTS: The study included 210 patients with 502 nodules (average: 2.39 (+/ 1.64) nodules/patient). Median size was 7 mm (3-60 mm). Malignancy was 0 % (0/116) in TIRADS 2, 1.79 % (1/56) in TIRADS 3, 76.13 % (185/243) in TIRADS 4 [subgroups: TIRADS 4A 5.88 % (1/17), TIRADS 4B 62.82 % (49/78), TIRADS 4C 91.22 % (135/148)], and 98.85 % (86/87) in TIRADS 5. With a cut-off point at TIRADS 4-5 to perform FNAB, we obtained: sensitivity 99.6 % (95 % CI: 98.9-100.0), specificity 74.35 % (95 % CI: 68.7-80.0), PPV 82.1 % (95 % CI: 78.0-86.3), NPV 99.4 % (95 % CI: 98.3-100.0), PLR 3.9 (95 % CI: 3.6-4.2) and an NLR 0.005 (95 % CI: 0.003-0.04) for malignancy. CONCLUSION: US-based TIRADS classification allows selection of nodules requiring FNAB and recognition of those with a low malignancy risk. KEY POINTS: * TIRADS classification allows accurate selection of thyroid nodules requiring biopsy (TIRADS 4-5). * The recognition of benign/possibly benign patterns can avoid unnecessary procedures. * This classification and its sonographic patterns are validated using surgical specimens. PMID- 27718079 TI - Breast dose reduction for chest CT by modifying the scanning parameters based on the pre-scan size-specific dose estimate (SSDE). AB - OBJECTIVE: To investigate the usefulness of modifying scanning parameters based on the size-specific dose estimate (SSDE) for a breast-dose reduction for chest CT. MATERIALS AND METHODS: We scanned 26 women with a fixed volume CT dose index (CTDIvol) (15 mGy) and another 26 with a fixed SSDE (15 mGy) protocol (protocol 1 and 2, respectively). In protocol 2, tube current was calculated based on the patient habitus obtained on scout images. We compared the mean breast dose and the inter-patient breast dose variability and performed linear regression analysis of the breast dose and the body mass index (BMI) of the two protocols. RESULTS: The mean breast dose was about 35 % lower under protocol 2 than protocol 1 (10.9 mGy vs. 16.8 mGy, p < 0.01). The inter-patient breast dose variability was significantly lower under protocol 2 than 1 (1.2 mGy vs. 2.5 mGy, p < 0.01). We observed a moderate negative correlation between the breast dose and the BMI under protocol 1 (r = 0.43, p < 0.01); there was no significant correlation (r = 0.06, p = 0.35) under protocol 2. CONCLUSION: The SSDE-based protocol achieved a reduction in breast dose and in inter-patient breast dose variability. KEY POINTS: * CT scan parameters can be modified based on the pre-scan SSDE. * The pre-scan SSDE is useful for a breast dose reduction. * The fixed SSDE protocol reduced individual variations in the breast dose. PMID- 27718081 TI - The assessment of peripapillary retinal nerve fiber layer and macular ganglion cell layer changes in obese children: a cross-sectional study using optical coherence tomography. AB - PURPOSE: To investigate the relationship between the obesity and optical coherence tomography (OCT) parameters. METHODS: We studied 54 obese and 33 non obese children and adolescents. Obesity was defined as BMI higher than 95th percentile (BMI SDS > 1.64). OCT measurements were performed in all participants. Anthropometric and biochemical variables were compared with OCT parameters of 174 eyes. RESULTS: In obese children, in all quadrants retinal nerve fiber layer (RNFL) thicknesses were significantly lower than non-obese children, and also ganglion cell-inner plexiform layer thicknesses in inferior and superiortemporal quadrants were significantly lower in the obese group. BMI SDS, insulin, HOMA-IR and triglyceride levels were negatively correlated with RNFL thickness, significantly (r = -0.386, p < 0.001; r = -0.229, p = 0.002; r = -0.188, p = 0.013; and r = -0.301, p = 0.000; respectively) in all subjects. CONCLUSIONS: Thinning in RNFL was detected in normal-looking discs of obese children, and this thinning negatively correlated with BMI SDS. Further studies including large series are needed to clarify whether obesity has an effect on RNFL thickness. PMID- 27718082 TI - Concentration of Glial Cell Line-Derived Neurotrophic Factor Positively Correlates with Symptoms in Functional Dyspepsia. AB - BACKGROUND: In patients with functional dyspepsia (FD), mild duodenal inflammation correlates with increased mucosal permeability. Enteric glial cells can produce glial cell line-derived neurotrophic factor (GDNF) to repair disrupted epithelial barrier function. AIMS: We examined the role of duodenal GDNF in FD pathophysiology and its association with dyspeptic symptoms. METHODS: Duodenal biopsies taken from FD patients and control subjects were used for analysis. GDNF protein expression and localization were examined. Cellular infiltration of eosinophils and mast cells was measured. We also examined the intercellular space between the adjacent epithelial cells at the apical junction complex using transmission electron microscopy. RESULTS: In FD patients, expression of GDNF protein was significantly increased compared with controls, 107.3 (95.3-136.7) versus 49.3 (38.0-72.6) pg/mg protein (median (interquartile range), p = 0.006), respectively. GDNF was localized in enteric glial cells, eosinophils, and epithelial cells. The number of eosinophils was significantly greater in FD patients than in controls, 1039 (923-1181) versus 553 (479-598) cells/mm2 (p = 0.021), respectively. The intercellular space was dilated at the adherent junction in FD patients compared to control patients, 32.4 (29.8-34.8) versus 22.0 (19.9-26.1) nm (p = 0.002), respectively. Intercellular distance positively correlated with the frequency of postprandial fullness and early satiation (p = 0.001, r = 0.837 and p = 0.009, r = 0.693, respectively). Expression of GDNF correlated with epigastric burning (p = 0.041, r = 0.552). CONCLUSIONS: Increased expression of duodenal GDNF might be involved in FD pathophysiology and symptom perception. PMID- 27718083 TI - Intestinal Lipomatosis and Chemotherapy: A Growing Concern. PMID- 27718085 TI - Hypogammaglobulinemia in infants receiving chronic peritoneal dialysis. AB - BACKGROUND: Peritonitis is a severe complication of chronic peritoneal dialysis (CPD) in infants. Few studies have been conducted to evaluate the relationship between hypogammaglobulinemia and peritonitis risk, and the potential benefit of intravenous immunoglobulins (IVIG) therapy in infants receiving CPD. METHODS: Patients aged 0-12 months at initiation of CPD between 1985 and 2012 were eligible for inclusion in this retrospective study. Data collected from the start of CPD up to 2 years post-dialysis initiation included patient demographics, dialysis characteristics, serum immunoglobulin (IgG) levels, IVIG administration history, infectious complications and outcomes. Cox regression analysis and linear mixed model analysis were used for statistical analysis. RESULTS: Twenty six consecutive patients were included in the study. Annualized peritonitis rates for infants aged 0-30 days (<=1-month age group; n = 16; 320.3 patient-months) and 31-365 days (>1-12-month age group; n = 10; 163.3 patient-months) at dialysis initiation were 0.27 (1 episode per 45.8 patient-months) and 0.15 (one episode per 81.7 patient-months), respectively. Seventy-six percent of the serum IgG levels were >1 standard deviation below the age-appropriate mean levels, and these did not differ in those who developed peritonitis versus those who did not (p = 0.39). Serum IgG levels were significantly lower in patients on CPD with oligoanuria than in non-oliguric patients (p = 0.04) and in patients on CPD for >90 days as compared to those who had received CPD for <90 days (p = 0.018). IVIG therapy was provided to 20 patients with hypogammaglobulinemia; this high prevalence of IVIG usage precluded any drawing of conclusion on the potential role of IVIG in the prevention of peritonitis. CONCLUSIONS: Hypogammaglobulinemia is a frequent complication of CPD during infancy. In our experience, it was not associated with an increased risk for peritonitis. PMID- 27718084 TI - Previous aminoglycoside use and acute kidney injury risk in non-critically ill children. AB - OBJECTIVES: Aminoglycosides (AG) are a group of bactericidal antibiotics with nephrotoxic effects that are commonly used in the treatment of hospitialized children. We have examined previous AG treatment as a risk factor for acute kidney injury (AKI) during current AG treatment. STUDY DESIGN: We performed a retrospective cohort study of children ranging in age from 1 month to 18 years who were treated with AG between October 2008 and April 2012 at Montreal's Children's Hospital. Children for whom no serum creatinine data (SCr) were available and those with baseline renal disease were excluded from the analysis. Main exposures were prior AG use (number and hours of prior treatments) and time since last AG treatment. The main outcome was AKI, defined on the basis of the Kidney Disease: Improving Global Outcomes guidelines. Logistic regression was used to examine exposure-outcome associations. RESULTS: AG treatments episodes with Stage 1, 2, and 3 AKI, respectively, were associated with a median of 98 [interquartile range (IQR) 339], 231 (IQR 688), and 111 (IQR 505) h of prior AG treatment, respectively, versus non-AKI (median 0, IQR 54 h) (p < 0.0001). AKI episodes were associated with a mean (+/- standard deviation) of 1.5 +/- 1.8 AG treatments in the previous 6 months, versus 0.9 +/- 1.6 AG treatments for non AKI. The number of AG-treatment days during the preceding 6 months [adjusted odds ratio (adjOR) 1.04, 95 % confidence interval (CI) 1.03-1.06; p < 0.001], younger age (adjOR 0.96, 95 % CI 0.93-0.99; p = 0.009), admission to hematology-oncology department (adjOR 3.88, 95 % CI 2.17-6.96; p < 0.001), and tobramycin use (adjOR 1.77, 95 % CI 1.04-3.02; p = 0.04) were independently associated with AKI. Episodes with Stage 1 and 2 AKI were associated with fewer days since last treatment compared to non-AKI treatment (p < 0.02 and p < 0.005, respectively; Mann-Whitney test). CONCLUSIONS: Based on these results, prior AG treatment is a risk factor for AKI and should be considered when dosing and monitoring hospitalized children being treated with AG. PMID- 27718051 TI - Are all people with diabetes and cardiovascular risk factors or microvascular complications at very high risk? Findings from the Risk and Prevention Study. AB - AIMS: To verify whether it is possible, in people with diabetes mellitus (DM) considered at very high cardiovascular (CV) risk, stratify this risk better and identify significant modifiable risk factor (including lifestyle habits) to help patients and clinicians improve CV prevention. METHODS: People with DM and microvascular diseases or one or more CV risk factors (hypertension, hyperlipidemia, smoking, poor dietary habits, overweight, physical inactivity) included in the Risk and Prevention study were selected. We considered the combined endpoint of non-fatal acute myocardial infarction and stroke and CV death. A multivariate Cox proportional analysis was carried out to identify relevant predictors. We also used the RECPAM method to identify subgroups of patients at higher risk. RESULTS: In our study, the rate of major CV events was lower than expected (5 % in 5 years). Predictors of CV events were age, male, sex, heart failure, previous atherosclerotic disease, atrial fibrillation, insulin treatment, high HbA1c, heart rate and other CV diseases while being physically active was protective. RECPAM analysis indicated that history of atherosclerotic diseases and a low BMI defined worse prognosis (HR 4.51 95 % CI 3.04-6.69). Among subjects with no previous atherosclerotic disease, men with HbA1c more than 8 % were at higher CV risk (HR 2.77; 95 % CI 1.86-4.14) with respect to women. CONCLUSIONS: In this population, the rate of major CV events was lower than expected. This prediction model could help clinicians identify people with DM at higher CV risk and support them in achieving goals of physical activity and HbA1c.

PMID- 27718086 TI - Serological and genetic complement alterations in infection-induced and complement-mediated hemolytic uremic syndrome. AB - BACKGROUND: The role of complement in the atypical form of hemolytic uremic syndrome (aHUS) has been investigated extensively in recent years. As the HUS associated bacteria Shiga-toxin-producing Escherichia coli (STEC) can evade the complement system, we hypothesized that complement dysregulation is also important in infection-induced HUS. METHODS: Serological profiles (C3, FH, FI, AP activity, C3d, C3bBbP, C3b/c, TCC, alphaFH) and genetic profiles (CFH, CFI, CD46, CFB, C3) of the alternative complement pathway were prospectively determined in the acute and convalescent phase of disease in children newly diagnosed with STEC HUS or aHUS. Serological profiles were compared with those of 90 age-matched controls. RESULTS: Thirty-seven patients were studied (26 STEC-HUS, 11 aHUS). In 39 % of them, including 28 % of STEC-HUS patients, we identified a genetic and/or acquired complement abnormality. In all patient groups, the levels of investigated alternative pathway (AP) activation markers were elevated in the acute phase and normalized in remission. The levels were significantly higher in aHUS than in STEC-HUS patients. CONCLUSIONS: In both infection-induced HUS and aHUS patients, complement is activated in the acute phase of the disease but not during remission. The C3d/C3 ratio displayed the best discrepancy between acute and convalescent phase and between STEC-HUS and aHUS and might therefore be used as a biomarker in disease diagnosis and monitoring. The presence of aberrations in the alternative complement pathway in STEC-HUS patients was remarkable, as well. PMID- 27718088 TI - When is biopsy-proven TIN not simply TIN? Answers. PMID- 27718089 TI - The relationship between solvent use and BTEX concentrations in occupational environments. AB - Indoor air quality is an increasing concern; it causes significant damage to health because it is recycled in confined environments for extended periods of time. Among the pollutants found in these environments, benzene, toluene, ethylbenzene, and xylenes (BTEX) are known for their potential toxic, mutagenic, and carcinogenic effects. This study monitored the BTEX concentrations in paint, carpentry, and varnish workplaces and evaluated the potential to cause adverse health effects on workers in these environments. Twenty samples were collected in workplaces, 20 samples were collected outside the area, and eight samples were taken of the products used. Samples were collected using coconut shell cartridges, and chemical analyses were performed by gas chromatography with mass spectrometry. Toluene presented higher indoor concentrations and indoor and outdoor ratios, indicating that the paint and varnish workplaces had significant BTEX sources. The highest benzene and toluene concentrations were obtained from the paint workshop, and higher concentrations of ethylbenzene and xylenes were obtained in the varnish workshop. The highest non-carcinogenic risks were obtained for m + p-xylenes in the varnish work place, and the second highest non carcinogenic risk was also determined for the same workshop. PMID- 27718091 TI - In Silico and In Vivo Experiments Reveal M-CSF Injections Accelerate Regeneration Following Muscle Laceration. AB - Numerous studies have pharmacologically modulated the muscle milieu in the hopes of promoting muscle regeneration; however, the timing and duration of these interventions are difficult to determine. This study utilized a combination of in silico and in vivo experiments to investigate how inflammation manipulation improves muscle recovery following injury. First, we measured macrophage populations following laceration injury in the rat tibialis anterior (TA). Then we calibrated an agent-based model (ABM) of muscle injury to mimic the observed inflammation profiles. The calibrated ABM was used to simulate macrophage and satellite stem cell (SC) dynamics, and suggested that delivering macrophage colony stimulating factor (M-CSF) prior to injury would promote SC-mediated injury recovery. Next, we performed an experiment wherein 1 day prior to injury, we injected M-CSF into the rat TA muscle. M-CSF increased the number of macrophages during the first 4 days post-injury. Furthermore, treated muscles experienced a swifter increase in the appearance of PAX7+ SCs and regenerating muscle fibers. Our study suggests that computational models of muscle injury provide novel insights into cellular dynamics during regeneration, and further, that pharmacologically altering inflammation dynamics prior to injury can accelerate the muscle regeneration process. PMID- 27718092 TI - White-Tailed Deer as an Ex Vivo Knee Model: Joint Morphometry and ACL Rupture Strength. AB - Animal joints are valuable proxies for those of humans in biomechanical studies, however commonly used quadruped knees differ greatly from human knees in scale and morphometry. To test the suitability of the cervine stifle joint (deer knee) as a laboratory model, gross morphometry, ACL cross section, and ACL rupture strength were measured and compared to values previously reported for the knees of humans and commonly studied animals. Twelve knee joints from wild white-tailed deer were tested. Several morphometry parameters, including bicondylar width (53.5 +/- 3.0 mm) and notch width (14.7 +/- 2.5 mm), showed a high degree of similarity to those of the human knee, while both medial (16.7 +/- 2.1 degrees ) and lateral (17.6 +/- 4.7 degrees ) tibial slopes were steeper than in humans but less steep than other quadrupeds. The median ACL rupture force (2054 N, 95% CI 2017-2256 N), mean stiffness (260 +/- 166 N/mm), mean length (33 +/- 7 mm), and mean cross sectional area (44.8 +/- 18.3 mm2) were also comparable to previously reported values for human knees. In our limited sample size, no significant sexual dimorphism in strength or morphometry was observed (p >= 0.05 for all parameters), though female specimens generally had steeper tibial slopes (lateral: p = 0.52, medial: p = 0.07). Our results suggest that the deer knee may be a suitable model for ex vivo studies of ACL rupture and repair. PMID- 27718090 TI - A comparative study of occurrence and fate of endocrine disruptors: diethyl phthalate and dibutyl phthalate in ASP- and SBR-based wastewater treatment plants. AB - Phthalates are endocrine-disrupting chemicals which affect endocrine system by bio-accumulation in aquatic organisms and produce adverse health effects in aquatic organisms as well as human beings, when come in contact. Present study focuses on occurrence and removal of two phthalates: diethylphthalate (DEP) and dibutylphthalate (DBP) in two full-scale wastewater treatment plants (WWTPs) i.e. sewage treatment plants (STPs) based on well-adopted technologies, activated sludge process (ASP) and sequencing batch reactor (SBR).Gas chromatography-mass spectrometry (GC-MS) analysis was performed for both wastewater and sludge sample for determination and identification of the concentration of these compounds in both STPs by monitoring the STPs for 9 months. It was observed that the concentration of DEP was less than DBP in the influent of ASP and SBR. Average concentrations of DEP and DBP in sludge sample of ASP were found to be 2.15 and 2.08 ng/g, whereas in SBR plant, these values were observed as 1.71 and 2.01 ng/g, respectively. Concerning the removal efficiency of DEP, SBR and ASP plants were found effective with removal efficiency of 91.51 and 91.03 %, respectively. However, in the case of DBP, SBR showed lower removal efficiency (85.42 %) as compared to ASP (92.67 %). Comparative study of both plants proposed that in ASP plant, DBP reduction was higher than the SBR. Fourier transformation infrared (FTIR) analysis also confirmed the same result of sludge analysis for both STPs. Sludge disposal studied with scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and thermo-gravimetric analysis (TGA) techniques confirmed that sludge of both STPs have high calorific value and can be used as fuel to make fuel-briquettes and bottom ash to make firebricks. PMID- 27718093 TI - Differential Regulation of Hippocampal IGF-1-Associated Signaling Proteins by Dietary Restriction in Aging Mouse. AB - Time-dependent alterations in several biological processes of an organism may be characterized as aging. One of the effects of aging is the decline in cognitive functions. Dietary restriction (DR), an intervention where the consumption of food is lessened but without malnutrition, is a well-established mechanism that has a wide range of important outcomes including improved health span, delayed aging, and extension of lifespan of various species. It also plays a beneficial role in protecting against age-dependent deterioration of cognitive functions, and has neuroprotective properties against neurodegenerative diseases. Insulin like growth factor (IGF)-1 plays an important role in the regulation of cellular and tissue functions, and relating to the aging process the most important pathway of IGF-1 is the phosphatidylinositol 3-kinase (PI3K) and protein kinase B (Akt/PKB) signaling cascade. Although many have studied the changes in the level of IGF-1 and its effect on neural proliferation, the downstream signaling proteins have not been fully elucidated. Hence in the present investigation, the IGF-1 gene expression and the normal endogenous levels of IGF1R (IGF-1 receptor), PI3K, Akt, pAkt, and pFoxO in the hippocampus of young, adult, and old mice were determined using real-time PCR and Western blot analyses. The effects of DR on these protein levels were also studied. Results showed a decrease in the levels of IGF-1, IGF1R, PI3K, and pAkt, while pFoxO level increased with respect to age. Under DR, these protein levels are maintained in adult mice, but old mice displayed diminished expression levels of these proteins as compared to ad libitum-fed mice. Maintenance of PI3K/Akt pathway results in the phosphorylation of FoxOs, necessary for the enhancement of neural proliferation and survival in adult mice. The down-regulation of IGF-I signaling, as observed in old mice, leads to increasing the activity of FoxO factors that may be important for the neuroprotective effects seen with DR. PMID- 27718094 TI - DasR positively controls monensin production at two-level regulation in Streptomyces cinnamonensis. AB - The polyether ionophore antibiotic monensin is produced by Streptomyces cinnamonensis and is used as a coccidiostat for chickens and growth-promoting agent for cattle. Monensin biosynthetic gene cluster has been cloned and partially characterized. The GntR-family transcription factor DasR regulates antibiotic production and morphological development in Streptomyces coelicolor and Saccharopolyspora erythraea. In this study, we identified and characterized the two-level regulatory cascade of DasR to monensin production in S. cinnamonensis. Forward and reverse genetics by overexpression and antisense RNA silence of dasR revealed that DasR positively controls monensin production under nutrient-rich condition. Electrophoresis mobility shift assay (EMSA) showed that DasR protein specifically binds to the promoter regions of both pathway-specific regulatory gene monRII and biosynthetic genes monAIX, monE and monT. Semi quantitative RT-PCR further confirmed that DasR upregulates the transcriptional levels of these genes during monensin fermentation. Subsequently, co overexpressed dasR with pathway-specific regulatory genes monRI, monRII or monH greatly improved monensin production.

PMID- 27718096 TI - TAZ Activator Is Involved in IL-10-Mediated Muscle Responses in an Animal Model of Traumatic Brain Injury. AB - The transcriptional coactivator with PDZ-binding motif (TAZ) functions as a downstream regulatory target in the Hippo signaling pathway that plays various roles. We previously developed a cell-based assay and identified the TAZ activator IBS008738 as a potential therapeutic target for glucocorticoid-induced atrophy. To further explore the application of IBS008738 in various muscle related diseases, we examined the function of IBS008738 in inflammatory cytokine mediated mouse muscle responses after traumatic brain injury (TBI). Preliminary screening suggested that IBS008738 treatments increased the levels of IL-10 in C2C12 cells. In TBI and sham control mice, we compared the effect of IBS008738 treatments on TNF alpha, IL-6, and IL-10 mRNA levels, muscle morphologic changes, and macrophage phenotype changes. Our findings support that the TAZ activator IBS008738 decreases muscle wasting by upregulating IL-10 and inhibiting TNF alpha and IL-6, and this process is implemented by changing the macrophage phenotypes. These results indicate a new mechanism of the TAZ activator as a potential therapy for atrophy.

AB - Indirubin plays an important role in the treatment of many chronic diseases and exhibits strong anti-inflammatory activity. However, the molecular mode of action during mastitis prophylaxis remains poorly understood. In this study, a lipopolysaccharide (LPS)-induced mastitis mouse model showed that indirubin attenuated histopathological changes in the mammary gland, local tissue necrosis, and neutrophil infiltration. Moreover, indirubin significantly downregulated the production of interleukin (IL)-1beta, IL-6, and tumor necrosis factor-alpha (TNF alpha). We explored the mechanism whereby indirubin exerts protective effects against LPS-induced inflammation of mouse mammary epithelial cells (MMECs). The addition of different concentrations of indirubin before exposure of cells to LPS for 1 h significantly attenuated inflammation and reduced the concentrations of the three inflammatory cytokines in a dose-dependent manner. Indirubin downregulated LPS-induced cyclooxygenase-2 (COX-2) and Toll-like receptor 4 (TLR4) expression, inhibited phosphorylation of the LPS-induced nuclear transcription factor-kappa B (NF-kB) P65 protein and its inhibitor IkBalpha of the NF-kB signaling pathway. Furthermore, indirubin suppressed phosphorylation of P38, extracellular signal-regulated kinase (ERK), and c-Jun NH2-terminal kinase (JNK) of the mitogen-activated protein kinase (MAPK) signal pathways. Thus, indirubin effectively suppressed LPS-induced inflammation via TLR4 abrogation mediated by the NF-kB and MAPK signaling pathways and may be useful for mastitis prophylaxis.

These spectral responses have been linked to several cognitive processes; including working memory, attention, perceptual binding and neuronal coordination. In this paper, we show how Bayesian methods can be used to finesse the ill-posed problem of reconstructing-and explaining-oscillatory responses. We offer an overview of recent developments in this field, focusing on (i) the use of MEG data and Empirical Bayes to build hierarchical models for group analyses-and the identification of important sources of inter-subject variability and (ii) the construction of novel dynamic causal models of intralaminar recordings to explain layer-specific activity. We hope to show that electrophysiological measurements contain much more spatial information than is often thought: on the one hand, the dynamic causal modelling of non-invasive (low spatial resolution) electrophysiology can afford sub-millimetre (hyper-acute) resolution that is limited only by the (spatial) complexity of the underlying (dynamic causal) forward model. On the other hand, invasive microelectrode recordings (that penetrate different cortical layers) can reveal laminar-specific responses and elucidate hierarchical message passing and information processing within and between cortical regions at a macroscopic scale. In short, the careful and biophysically grounded modelling of sparse data enables one to characterise the neuronal architectures generating oscillations in a remarkable detail.

AB - Neurovascular emergencies, consisting of acute ischemic stroke, non-traumatic aneurysmal subarachnoid hemorrhage, arteriovenous malformation, dural arteriovenous fistula, and carotid- cavernous fistula, can have an acute presentation to the emergency department. Radiologists should have an understanding of these processes and their imaging findings in order to provide a prompt and accurate diagnosis. Neurointerventional radiology plays a critical role in providing additional diagnostic information and potentially curative treatment. Understanding the grading scales used to evaluate and prognosticate these neurovascular emergencies can help expedite management for best possible patient outcomes.

AB - Impaired sleep patterns are common symptoms of Alzheimer's disease (AD). Cellular mechanisms underlying sleep disturbance in AD remain largely unknown. Here, using a Drosophila Abeta42 AD model, we show that Abeta42 markedly decreases sleep in a large population, which is accompanied with postdevelopmental axonal arborization of wake-promoting pigment-dispersing factor (PDF) neurons. The arborization is mediated in part via JNK activation and can be reversed by decreasing JNK signaling activity. Axonal arborization and impaired sleep are correlated in Abeta42 and JNK kinase hemipterous mutant flies. Image reconstruction revealed that these aberrant fibers preferentially project to pars intercerebralis (PI), a fly brain region analogous to the mammalian hypothalamus. Moreover, PDF signaling in PI neurons was found to modulate sleep/wake activities, suggesting that excessive release of PDF by these aberrant fibers may lead to the impaired sleep in Abeta42 flies. Finally, inhibition of JNK activation in Abeta42 flies restores nighttime sleep loss, decreases Abeta42 accumulation, and attenuates neurodegeneration. These data provide a new mechanism by which sleep disturbance could be induced by Abeta42 burden, a key initiator of a complex pathogenic cascade in AD. PMID- 27718104 TI - The Family Socialization Interview-Revised (FSI-R): a Comprehensive Assessment of Parental Disciplinary Behaviors. AB - Elucidating the complex mechanisms by which harsh parenting increases risk of child psychopathology is key to targeted prevention. This requires nuanced methods that capture the varied perceptions and experiences of diverse families. The Family Socialization Interview-Revised (FSI-R), adapted from an interview developed by Dodge et al. (Child Development, 65, 649-665, 1994), is a comprehensive, semi-structured interview for characterizing methods of parental discipline used with young children. The FSI-R coding system systematically rates parenting style, usual discipline techniques, and most intense physical and psychological discipline based on rater judgment across two eras: (1) birth to the previous year, and (2) the previous year to present. The current study examined the psychometric properties of the FSI-R in a diverse, high-risk community sample of 386 mothers and their children, ages 3 to 6 years. Interrater reliability was good to excellent for codes capturing physically and psychologically harsh parenting, and restrictive/punitive parenting styles. Findings supported the FSI-R's convergent and incremental validity. Importantly, the FSI-R demonstrated incremental utility, explaining unique variance in children's externalizing and internalizing symptoms beyond that explained by traditional surveys and observed parenting. The FSI-R appeared particularly promising for capturing risk associated with young children's depressive symptoms, as these were generally not significantly associated with other measures of harsh parenting. Overall, findings support the added value of the FSI R within a multi-method assessment of disciplinary practices across early child development. Future implications for prevention are discussed. PMID- 27718105 TI - Bruises in beef cattle at slaughter in Mexico: implications on quality, safety and shelf life of the meat. AB - In emergent economies and developing countries of Africa, Asia and Latin America, the major cause for carcass rejection from the international market is bruising; nevertheless, many of these carcases are destined to local markets and meat processing industries for human consumption. Therefore, the aim of the present study was to assess the effect of bruised meat on pH, microbiologic count and biogenic amine (BA) profiles along 21 days of ageing (sampling 1st, 7th, 14th and 21st day) with two packaging method (plastic bag vs vacuum) at 4 degrees C. A total of 50 bruised carcasses were sampled from 1000 young bulls (Brown Swiss X Zebu) of 18-24 months old and an average live weight of 450 +/- 66 kg. The results showed significant differences between packaging systems and bruised vs non-bruised meat. The bruised meat caused higher biogenic amine concentrations than did non-bruised meat. We conclude that bruised meat favoured increments of biogenic amine concentrations, even more than did non-bruised meat. The plastic bag + vacuum system limited the increments of BA concentration during storage time therefore it improved shelf life of meat. These results emphasized the importance of implementing best management practices during pre-slaughter operations of cattle in order to reduce a possible risk factor for bruised meat. PMID- 27718106 TI - Challenges for beef production in smallholder communities with low reproductive management skills: a case study from Northern Lao PDR. AB - Improved large ruminant productivity is increasingly acknowledged as a pathway for the alleviation of rural poverty and food insecurity in smallholder communities in Southeast Asia; yet, in much of Laos, bovine reproductive management is practically absent. Large ruminant reproduction skills were studied, using face-to-face surveys (n=60) of the knowledge, attitudes, and practices (KAP) of farmers, plus an extension of an examination of parameters of reproductive efficiency (n = 1786 cattle and 434 buffalo) in the northern provinces of Luang Prabang and Xieng Khouang. The surveys particularly involved female farmers to provide gender-disaggregated data, with females making up 38.3 % of participants. Results confirmed that KAPs of smallholder farmers on bovine reproductive management were low (34-46 %) with trends toward higher KAP scores in male survey respondents. Poor reproductive parameters were identified in both provinces, with low calving percentages of 54-75 and 45-54 % in cattle and buffalo groups, respectively, and prolonged inter-calving intervals of 14.1-19.8 and 26.0 months for the cattle and buffalo groups, respectively. Improving the reproductive efficiency of large ruminants in the northern upland regions would enable smallholder farmers to be more effectively engaged in the dramatic economic growth of the Southeast Asia region, although these findings indicate that intensive training and supportive interventions are required to improve large ruminant reproductive outcomes in communities that have low-level large ruminant husbandry skills. PMID- 27718107 TI - Nutraceutic effect of free condensed tannins of Lysiloma acapulcensis (Kunth) benth on parasite infection and performance of Pelibuey sheep. AB - Forty-five Pelibuey sheep were experimentally infested with nematodes to evaluate the effect of three free condensed tannin (FCT) levels of Lysiloma acapulcensis on fecal egg counts (FECs), packed cell volumes (PCV), ocular mucosa colors (OMC), average daily gain (ADG), and adult nematode count. Five treatments were used: 12.5, 25.0, and 37.5 mg of FCT kg-1 of body weight (BW); sterile water (control); and ivermectine (0.22 mg kg-1 of BW) as chemical group. The data were processed through repeated measurement analysis. Even though the three FCT doses decreased (P < 0.05) the FEC, the highest reduction was obtained with 37.5 mg kg 1 of BW. No differences were observed in PCV and OMC. Higher ADG (P < 0.05) was observed with 37.5 mg kg-1 of BW of FCT. The count of adult nematodes (females and males) in the higher dose of FCT was similar to chemical treatment. Dose of 37.5 mg kg-1 of BW decreased the parasite infection and improved the lamb performance. Therefore, this dose could be used as a nutraceutic product in sheep production. PMID- 27718108 TI - Effect of dried rumen digesta pellet levels on feed use, rumen ecology, and blood metabolite in swamp buffalo. AB - The aim of this experiment was to determine the effect of dried rumen digesta pellet levels on feed intake, digestibility, rumen ecology, and blood metabolites in swamp buffalo. Four 2-year-old male swamp buffalo with an initial body weight (BW) of 150 +/- 10.0 kg were randomly assigned according to a 4 * 4 Latin square design to receive four levels of dried rumen digesta pellets (DRDPs). The dietary treatments were supplementation of DRDP at 0, 50, 100, and 150 g dry matter/day, respectively. Total feed intake was significantly different among treatments (p < 0.05) and was highest in the 150 g/day DRDP supplement (2.68 kg/day). Intakes of neutral detergent fiber (NDF) and acid detergent fiber did not affect DRDP levels, while intakes of organic matter and crude protein (CP) were altered significantly when 150 g of DRDP was used (p < 0.05). Buffalo fed with DRDP at 150 g/day had the highest CP and NDF digestibility (p < 0.05). DRDP supplementation did not affect rumen pH, and temperature and the concentration of ruminal ammonia-nitrogen and blood urea nitrogen were not altered among the treatments. The mean value of fungal zoospores in the buffalo was significantly different among treatments and was highest in supplementation with DRDP at 150 g. The mean value of propionic acid was significantly different at various levels of DRDP; it was highest in the group fed with 150 g DRDP (p < 0.05). Thus, supplementation of DRDP at 150 g improved feed use and increased fungal zoospore population. In addition, DRDP feeding is recommended, since it has positive economic impacts and helps control environmental pollution. PMID- 27718109 TI - Spineless cactus as a replacement for sugarcane in the diets of finishing lambs. AB - The effects of replacement of sugarcane by spineless cactus (0, 33, 66, and 100 % on dry matter (DM) basis) were evaluated on intake, digestibility of nutrients, ingestive behavior, and performance of finishing lambs. Thirty-six non-castrated Santa Ines lambs at 4 months of age and an initial body weight of 22 +/- 2.3 kg were assigned in a randomized block design. A quadratic effect was found for intake of DM, organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), and digestible organic matter (DOM), with maximum values of 1.31, 1.19, 0.219, 0.358, and 0.845 g/day estimated with 42.5, 38.5, 38.8, 21.3, and 44.9 % replacement level, respectively. The digestibility of DM, OM, CP, and EE increased linearly; however, there was a quadratic effect on NDF digestibility with maximum value estimated of 500 g/kg with 64.2 % replacement level. Rumination time, total chewing, and rumination efficiency decreased linearly with the replacement levels; however, idle time increased linearly. A quadratic effect was found for final weight, body weight gain, and total weight gain with maximum values estimated of 38.6 kg, 0.232 kg/day, and 16.2 kg with 39.1, 38.2, and 40.4 % replacing levels. The replacement of 49.5 % sugarcane by spineless cactus can be recommended as optimal level, and problems related to intake, digestibility, and performance are concentrated outside that level. PMID- 27718111 TI - Prediction of municipal solid waste generation using artificial neural network approach enhanced by structural break analysis. AB - This paper presents the development of a general regression neural network (GRNN) model for the prediction of annual municipal solid waste (MSW) generation at the national level for 44 countries of different size, population and economic development level. Proper modelling of MSW generation is essential for the planning of MSW management system as well as for the simulation of various environmental impact scenarios. The main objective of this work was to examine the potential influence of economy crisis (global or local) on the forecast of MSW generation obtained by the GRNN model. The existence of the so-called structural breaks that occur because of the economic crisis in the studied period (2000-2012) for each country was determined and confirmed using the Chow test and Quandt-Andrews test. Two GRNN models, one which did not take into account the influence of the economic crisis (GRNN) and another one which did (SB-GRNN), were developed. The novelty of the applied method is that it uses broadly available social, economic and demographic indicators and indicators of sustainability, together with GRNN and structural break testing for the prediction of MSW generation at the national level. The obtained results demonstrate that the SB GRNN model provide more accurate predictions than the model which neglected structural breaks, with a mean absolute percentage error (MAPE) of 4.0 % compared to 6.7 % generated by the GRNN model. The proposed model enhanced with structural breaks can be a viable alternative for a more accurate prediction of MSW generation at the national level, especially for developing countries for which a lack of MSW data is notable. PMID- 27718110 TI - HIV-1-derived single-stranded RNA acts as activator of human neutrophils. AB - Neutrophils are key effector cells of the innate immune system and are involved in the host defense against invading pathogens such as viruses. Recently, it was reported that HIV-1-neutrophil interaction triggers neutrophil activation and promotes expression of Toll-like receptors (TLRs). Here, we assessed the role of single-stranded RNA40 (ssRNA40) derived from HIV-1 in neutrophil activation. We observed functional activation of neutrophils in response to HIV-1-derived ssRNA40 based on the expression of TLR7/8, RIG-I, and MDA5, induction of cytokines (IL-6 and TNF-alpha), and the production of reactive oxygen species (ROS). Additionally, ssRNA40 promoted the expression of CD62L and TNF-alpha and the production of ROS in the presence of the TLR2 agonist Pam2CSK4. ssRNA40 together with R848 (a TLR7/8 agonist) increased CD11b expression but decreased CD62L expression. Furthermore, decreased IL-6 expression was observed in the presence of the TLR4 agonist LPS. Finally, we found that ssRNA40 promotes RIG-I and MDA5 expression in the presence of the TLR2, TLR4 and TLR7/8 agonists. This study demonstrates a functional response of TLRs in neutrophils challenged with ssRNA40, suggesting that TLRs could be involved in the innate immune response observed during HIV infection, which might be mediated by its genome. PMID- 27718113 TI - Application of electrochemical processes to membrane bioreactors for improving nutrient removal and fouling control. AB - Membrane bioreactor (MBR) technology is becoming increasingly popular as wastewater treatment due to the unique advantages it offers. However, membrane fouling is being given a great deal of attention so as to improve the performance of this type of technology. Recent studies have proven that the application of electrochemical processes to MBR represents a promising technological approach for membrane fouling control. In this work, two intermittent voltage gradients of 1 and 3 V/cm were applied between two cylindrical perforated electrodes, immersed around a membrane module, at laboratory scale with the aim of investigating the treatment performance and membrane fouling formation. For comparison purposes, the reactor also operated as a conventional MBR. Mechanisms of nutrient removal were studied and membrane fouling formation evaluated in terms of transmembrane pressure variation over time and sludge relative hydrophobicity. Furthermore, the impact of electrochemical processes on transparent exopolymeric particles (TEP), proposed as a new membrane fouling precursor, was investigated in addition to conventional fouling precursors such as bound extracellular polymeric substances (bEPS) and soluble microbial products (SMP). All the results indicate that the integration of electrochemical processes into a MBR has the advantage of improving the treatment performance especially in terms of nutrient removal, with an enhancement of orthophosphate (PO4-P) and ammonia nitrogen (NH4-N) removal efficiencies up to 96.06 and 69.34 %, respectively. A reduction of membrane fouling was also observed with an increase of floc hydrophobicity to 71.72 %, a decrease of membrane fouling precursor concentrations, and, thus, of membrane fouling rates up to 54.33 %. The relationship found between TEP concentration and membrane fouling rate after the application of electrochemical processes confirms the applicability of this parameter as a new membrane fouling indicator. PMID- 27718112 TI - Lifetime cancer risk assessment for inhalation exposure to di(2-ethylhexyl) phthalate (DEHP). AB - The plasticizer di(2-ethylhexyl) phthalate (DEHP) is ubiquitous in the environment and considered as carcinogen; however, the carcinogenic risk of human exposure to DEHP in the air via inhalation is lacking. A probabilistic incremental lifetime cancer risk (ILCR) model was implemented to quantitatively estimate the potential cancer risk of DEHP via human inhalation by using Monte Carlo simulation. We assessed the cancer risk in different age groups (children, adolescents, and adults) exposed to different DEHP concentrations (background low, indoor moderate, and occupational high) for different durations (2, 8, and 20 years). Results showed that the cancer risk of exposure to DEHP was below the acceptable limit (10-6) in the ambient air but was serious in indoor and occupational environments even at short exposure duration (2 years). The cancer risk of DEHP via inhalation in children was lower than that in adolescents and adults, but the risk in children via dermal and oral exposure to indoor dust and soft PVC toys should be considered. Sensitivity analysis indicated that the exposure concentration of DEHP was the strongest factor that influenced ILCR. Our work provides the evidence of cancer risk of DEHP via inhalation and highlights the risk in indoor and occupational environments. PMID- 27718114 TI - A follow-up on the analytical study of discolouration of the marble statues of Orsanmichele in Florence. AB - The research complements the complex study carried out to understand the source of brown discolourations of ten marble statues in the Church of Orsanmichele in Florence, Italy. Originally located in exterior niches, the statues were restored to reverse the extensive alterations they had undergone throughout the centuries. One of the major alterations was the application of a dark brown patina that dated just after 1789. After the statues were placed indoors, brownish discolourations started to appear on their surfaces. Cross sections were examined using FTIR mapping and immunological methods. In parallel, the pyrolysis-gas chromatography/mass spectrometry (py-GC/MS) data already obtained from the statues' scrapings were compared with data from aged casein films applied to microscope glass slides and aged milk-treated marble. All the statues had been treated with milk-based substances before the time the bronze patina was applied. The values of temperature and illumination of the room were important factors in the ageing of organic substances and in the formation of calcium oxalates. It is likely that products of thermo-oxidation and photo-oxidation of the oils together with the oxalates caused the darkening. The marble samples corresponded to a Lunense provenance. PMID- 27718116 TI - Assessing of policies and practices for occupational exposure to blood-borne viral infections in Tanta University Hospitals, Egypt. AB - One of the best ways to investigate and improve the effectiveness of polices for prevention and control of infections is through systematic and rigorous evaluation of the structural, functional, and practical elements of these polices. To assess the policies for managing occupational exposure to blood-borne viral infections in Tanta University Hospitals. A cross-sectional survey was carried out. A checklist was used to collect data related to the hospital policy regarding occupational exposure to blood-borne viral infections which was filled by direct personal interviews with the members of infection control (IC) committee of Tanta University Hospitals where the percentage of those in compliance with specific occupational management policies were reported. All studied participants reported lack of access to written infection control manual and only 14.3 % reported that infection control policies and procedures are updated yearly. Only 32.5 % of studied healthcare workers (HCWs) were not aware by the availability of a needle injury clinic. Only 28.6 % of the members of IC committee reported that pre-placement screening of HCWs for baseline blood tests for HBV, HCV, or HIV was conducted; however, periodic screening for these infections was not conducted as reported by all of the members. Among the members of IC committee, 57.1 % recorded availability of post-exposure evaluation. Only 42.8 % of the members of IC committee reported ensuring HCWs' confidentiality when reporting their exposure incidents. Both exposure management policies and practices were not aligning with the national guidelines. PMID- 27718115 TI - Association between inflammation processes, DNA damage, and exposure to environmental pollutants. AB - Environmental exposure to pollutants, especially polycyclic aromatic hydrocarbons (PAHs), could lead to carcinogenesis development. However, there is a gap on the mechanisms involved in this effect. Therefore, the aim of this study was to investigate the potential relationship between exposure to environmental air pollution and inflammation process in DNA damage in taxi drivers. This study included 45 taxi drivers and 40 controls; non-smokers composed both groups. Biological monitoring was performed through quantification of urinary 1 hydroxypyrene (1-OHP). ICAM-1 (CD54) expression, NTPDase activity, inflammatory cytokine (IL-1beta, IL-6, IL-10, TNF-alpha and IFN-gamma) levels, and comet and micronucleus assays were evaluated. The results demonstrated that 1-OHP levels, ICAM-1 expression, NTPDase activity, and DNA damage biomarkers (% tail DNA and micronucleus frequency) were increased in taxi drivers compared to the control group (p < 0.01). Moreover, significant associations were found between 1-OHP levels and ICAM-1 expression, % tail DNA, and micronucleus frequency (p < 0.05). Besides, pro-inflammatory cytokine levels were positively correlated to % tail DNA and micronucleus frequency (p < 0.001). Our findings suggest an important association between environmental exposure to air pollution with increase of ICAM 1 expression and NTPDase activity in taxi drivers. Additionally, the multiple regression linear-analysis demonstrated association between IL-6 and DNA damage. Thus, the present study has provided important evidence that, in addition to environmental exposure to air pollutants, the inflammation process may contribute to DNA damage. PMID- 27718118 TI - Assessment of Minimum Inhibitory Concentrations of Telavancin by Revised Broth Microdilution Method in Phase 3 Hospital-Acquired Pneumonia/Ventilator-Associated Pneumonia Clinical Isolates. AB - INTRODUCTION: The broth microdilution method (BMD) for testing telavancin minimum inhibitory concentrations (MICs) was revised (rBMD) in 2014 to improve the accuracy, precision, and reproducibility of the testing method. The aim of this study was to determine the effect of the revised method on telavancin MIC values for Staphylococcus aureus (S. aureus) clinical isolates obtained from hospital acquired pneumonia (HAP) patients. METHODS: Isolates from patients who participated in the phase 3 Assessment of Telavancin for Treatment of HAP Studies were retested using the rBMD method. RESULTS: Retesting of 647 isolates produced a range of telavancin MIC values from 0.015 ug/mL to 0.12 ug/mL with MIC50/90 values of 0.06/0.06 ug/mL for the total pool of samples. For methicillin resistant S. aureus (MRSA), MIC50/90 values were 0.06/0.12 ug/mL. These values are up to 4-fold lower than MIC50/90 values obtained using the original method. These results were used in part to justify lowering the telavancin breakpoints. All tested isolates remained susceptible to telavancin at the revised susceptibility breakpoint of <=0.12 ug/mL. Overall, the clinical cure rate for microbiologically evaluable telavancin-treated patients was 78% for S. aureus, 76% for patients with MRSA, and 79% for patients with isolates with reduced susceptibility to vancomycin (MIC >=1 ug/mL). CONCLUSION: Results from the rBMD method support the in vitro potency of telavancin against S. aureus. TRIAL REGISTRATION: ATTAIN (NCT00107952 and NCT00124020).

AB - Short-chain peptides play important roles in plant development and responses to abiotic and biotic stresses. Here, we characterized a gene of unknown function termed OsDT11, which encodes an 88 amino acid short-chain peptide and belongs to the cysteine-rich peptide family. It was found that the expression of OsDT11 can be activated by polyethylene glycol (PEG) treatment. Compared with wild-type lines, the OsDT11-overexpression lines displayed dramatically enhanced tolerance to drought and had reduced water loss, reduced stomatal density, and an increased the concentration of abscisic acid (ABA). The suppression of OsDT11 expression resulted in an increased sensitivity to drought compared to wild-type expression. Several drought-related genes, including genes encoding abscisic acid (ABA) signaling markers, were also strongly induced in the OsDT11-overexpressing lines. Moreover, the expression of OsDT11 was repressed in ABA-insensitive mutant Osbzip23 and Os2H16 RNAi lines. These results suggest that OsDT11-mediated drought tolerance may be dependent on the ABA signaling pathway.

AB - Forty-four-year-old male with ulcerative colitis (UC) for 11 years reported frequent relapse despite daily sulfasalazine 4 g, azathioprine 125 mg, and rectal 5-aminosalicylic acid. Repeated use of corticosteroids led to cataract. At enrollment, he was passing eight stools a day with blood with a Mayo score of 9 (3+1+3+2). Stool was negative for ova/cysts/acid fast bacilli and Clostridium difficile toxin assay. Rectal biopsy showed cryptitis, crypt abscess, and crypt distortion with no inclusion bodies, and cytomegalovirus DNA was negative. Following informed consent and approval from IEC, three sessions of fecal microbiota transplant (FMT) were performed at intervals of 2 weeks. The donor was a 34-year-old relative with no history of gastrointestinal illness, no use of antibiotics over 3 months, and free from transmissible disease as per standard protocol. At colonoscopy, 350 mL of blended and filtered donor stool, drawn into seven syringes of 50 cm3, was instilled from terminal ileum to sigmoid. Follow up sigmoidoscopy and rectal biopsy were done monthly for 6 months. There was symptomatic, colonoscopic, and histopathological improvement with the Mayo scores of 4.1 and 0 at 4.8 and 12 weeks post FMT. Azathioprine and sulfasalazine were tapered sequentially between months 4 and 6 of FMT. He remains in clinical and endoscopic remission 8 months after FMT and 2 months after withdrawal of all medication. Colonoscopic FMT may be effective in inducing drug-free remission in patients with active UC. PMID- 27718120 TI - Ceftriaxone-Associated Biliary and Cardiopulmonary Adverse Events in Neonates: A Systematic Review of the Literature. AB - BACKGROUND: Ceftriaxone is a third-generation cephalosporin with broad-spectrum activity against both Gram-positive and Gram-negative bacteria. Despite its effectiveness, its use for the treatment of infections in neonatal patients has been limited because of concern about its potential toxicity. OBJECTIVE: Our aim was to review the literature for an association between ceftriaxone and cardiopulmonary events, hyperbilirubinemia, and pseudolithiasis among neonates. METHODS: We searched PubMed and EMBASE and included studies that evaluated ceftriaxone safety in neonates. Study bias was evaluated in the following domains: exposure measurement, outcome measurement, attrition, generalizability, confounding, statistical analysis, and reporting. RESULTS: We included nine studies regarding ceftriaxone side effects, primarily spontaneous reports, published case reports, and small case series. Reports of bilirubin displacement attributed to ceftriaxone included increases in serum bilirubin necessitating antibiotic change in a subset of infants after administration of ceftriaxone. One study described self-resolving biliary sludge after ceftriaxone administration in six of 80 infants. Cardiopulmonary adverse events included a report of eight cardiopulmonary events related to concomitant ceftriaxone-calcium infusion, including seven infant deaths. Additional cardiopulmonary events reported included perinatal asphyxia, pulmonary hypertension, and thrombocytosis. However, the available literature had small sample sizes, poor external validity, and inconsistent outcome ascertainment methods, which made it impossible to estimate the magnitude of risk. DISCUSSION: Concomitant administration of intravenous ceftriaxone and calcium-containing solutions should be avoided in neonates. However, further controlled studies are needed to assess whether bilirubin displacement associated with the use of ceftriaxone is clinically relevant, particularly in healthy term and near-term neonates with mild hyperbilirubinemia. PMID- 27718121 TI - What Are the Risk Factors for Revision Surgery After Hip Arthroscopy for Femoroacetabular Impingement at 7-year Followup? AB - BACKGROUND: In recent years, surgical treatment of symptomatic femoroacetabular impingement (FAI) has been increasingly performed using arthroscopy. Bony pathomorphologies and damage to the labrum as well as cartilage defects can be addressed with comparable results to open surgery with overall less surgery related complications. Despite the increasing importance of hip arthroscopy, however, reports on midterm clinical and radiographic outcomes and comparison to open surgical hip dislocation are scarce. QUESTIONS/PURPOSES: (1) What are the clinical and radiographic outcomes at a mean 7-year followup; (2) what is the cumulative 7-year survivorship, using the endpoints of THA, progression of osteoarthritis according to Tonnis, or poor clinical outcome with a Merle d'Aubigne score of less than 15 points, of hips with symptomatic FAI treated arthroscopically; and (3) what factors were associated with revision surgery? METHODS: Between 2003 and 2008 we performed a total of 62 arthroscopic procedures (60 patients) for FAI. For the same indication, we also performed 571 surgical hip dislocations during that time. Standardized treatment was femoral offset correction, acetabular rim trimming, or both and treatment of labral or chondral defects. An arthroscopic approach was generally used if the pathomorphology was located in the anterosuperior quadrant of the hip and was gradually used for more complex cases. We excluded 10 hips (10 patients) in which the standardized treatment was not achieved and no offset correction or acetabular rim trimming was performed. Of the remaining 52 hips (50 patients), 39 hips underwent isolated femoral offset correction, four hips isolated acetabular rim trimming, and nine hips both procedures. At a mean followup of 7 years (range, 5-11 years), the Merle d'Aubigne clinical score was obtained and plain radiographs were examined (Tonnis grade, heterotopic ossification, lateral center-edge [LCE] angle, acetabular index [AI], extrusion index, alpha angle, and pistol grip deformity). Cumulative survivorship was calculated according to Kaplan-Meier using conversion to THA, progression of osteoarthritis (one or more Tonnis grades), or poor clinical outcome (Merle d'Aubigne score < 15 points) as endpoints. Cox regression analysis was used to identify univariate factors associated with revision surgery. RESULTS: At last followup we detected a significant but possibly not clinically relevant increase in Merle d'Aubigne scores from preoperative levels to latest followup (14 +/- 1 versus 16 +/- 2, mean difference 2 points with a 95% confidence interval [95% CI] -3 to 7, p < 0.001). Six hips showed progression of osteoarthritis. Cumulative survivorship (hips free from conversion to THA, progression of osteoarthritis, or poor clinical outcome) of hips treated with hip arthroscopy for FAI at a mean followup of 7 years was 81% (95% CI, 68%-95%). Two patients (two hips, 4%) underwent THA at 7 and 9 years, respectively. An increased preoperative acetabular coverage (LCE angle, AI), increased offset in the superior portion of the femoral neck (pistol grip deformity), and a remaining pistol grip deformity postoperatively were associated with revision surgery. Any treatment of the labrum did not influence the outcome. Factors associated with failure could not be identified. CONCLUSIONS: In this series of patients with arthroscopic treatment of symptomatic FAI, hip arthroscopy resulted in an intact hip without progression of osteoarthritis and with a Merle d'Aubigne score of >= 15 points in 81% of patients at 7-year followup. Increased acetabular coverage and femoral pistol grip deformity were risk factors for revision surgery. LEVEL OF EVIDENCE: Level IV, therapeutic study. PMID- 27718124 TI - The impact of manual threshold selection in medical additive manufacturing. AB - PURPOSE: Medical additive manufacturing requires standard tessellation language (STL) models. Such models are commonly derived from computed tomography (CT) images using thresholding. Threshold selection can be performed manually or automatically. The aim of this study was to assess the impact of manual and default threshold selection on the reliability and accuracy of skull STL models using different CT technologies. METHOD: One female and one male human cadaver head were imaged using multi-detector row CT, dual-energy CT, and two cone-beam CT scanners. Four medical engineers manually thresholded the bony structures on all CT images. The lowest and highest selected mean threshold values and the default threshold value were used to generate skull STL models. Geometric variations between all manually thresholded STL models were calculated. Furthermore, in order to calculate the accuracy of the manually and default thresholded STL models, all STL models were superimposed on an optical scan of the dry female and male skulls ("gold standard"). RESULTS: The intra- and inter observer variability of the manual threshold selection was good (intra-class correlation coefficients >0.9). All engineers selected grey values closer to soft tissue to compensate for bone voids. Geometric variations between the manually thresholded STL models were 0.13 mm (multi-detector row CT), 0.59 mm (dual-energy CT), and 0.55 mm (cone-beam CT). All STL models demonstrated inaccuracies ranging from -0.8 to +1.1 mm (multi-detector row CT), -0.7 to +2.0 mm (dual-energy CT), and -2.3 to +4.8 mm (cone-beam CT). CONCLUSIONS: This study demonstrates that manual threshold selection results in better STL models than default thresholding. The use of dual-energy CT and cone-beam CT technology in its present form does not deliver reliable or accurate STL models for medical additive manufacturing. New approaches are required that are based on pattern recognition and machine learning algorithms.

AB - Excessive exercise induces an inflammatory response caused by oxidative stress, which delays recovery of damaged muscle fibers. The reduction of inflammatory response is important for skeletal muscle homeostasis. Peroxisome proliferator activated receptor gamma (PPARgamma) is an anti-inflammatory molecule, but the role of PPARgamma in skeletal muscle as anti-inflammatory activity is not clear. Thus, this study examined the anti-inflammatory role of PPARgamma against H2O2 induced oxidative stress in skeletal muscle. Sprague Dawley (SD) rats were exercised on a treadmill to induce oxidative stress. In vitro oxidative stress was evaluated in differentiated C2C12 cells stimulated using 200 MUM H2O2. Inflammation-related molecules were determined by immunohistochemistry and Western blot analysis. Expressions of the inflammatory molecules tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1beta), cyclooxygenase-2 (COX 2), and matrix metalloproteinase-2 (MMP-2) in muscles of the acute exercise group were highly increased. PPARgamma was also highly expressed in these muscles. These inflammatory molecules were also markedly increased in C2C12 cells with H2O2 stimulation. However, PPARgamma overexpression in C2C12 transfected by Ad/PPARgamma dramatically reduced the inflammatory molecules. PPARgamma also enhanced the anti-oxidants molecules like Cu/Zn-SOD, Mn-SOD, and hemeoxygenase-1 by reducing the generation of ROS, even in the presence of H2O2. PPARgamma displayed dual anti-inflammatory and anti-oxidant roles by inhibiting the mitogen activated protein kinase (MAPK) pathway and translocation of nuclear transcriptional factor-kappaB (NF-kappaB) from the cytosol to the nucleus. These results demonstrate a potential role of PPARgamma in protecting muscle fibers against oxidative stress caused by excessive acute exercise due to its anti inflammatory and anti-oxidant activity exerted by inhibition of the MAPK/NF kappaB pathway. PMID- 27718125 TI - Expression and significance of Hippo/YAP signaling in glioma progression. AB - Dysregulation of Hippo/YAP signaling leads to aberrant cell growth and neoplasia. Although the roles and regulation of Hippo/YAP signaling were extensively studied in cancer biology recently, study systematically checking the expression pattern of core components of this pathway at the tumor tissue level remains lacking. In this study, we thoroughly examined the profile of core components of Hippo/YAP signaling in patient specimens both at the mRNA and at protein levels. We found that the mRNA level of YAP1/TAZ and their target genes, CRY61, CTGF, and BIRC5, was remarkably amplified in glioma tissues. Consistently, the protein level of YAP1/TAZ increased and meanwhile those of p-YAP1/p-TAZ and LATS1/2 decreased in gliomas. Unexpectedly, both the mRNA and protein levels of MST1/2 increased in the glioma tissues, inconsistent with its presumed tumor suppressor identity. In addition, over-expression of LATS2 decreased, while over-expression of YPA1 increased the cell proliferation ability. Furthermore, based on the data from the free public database, YAP1/TAZ and BIRC5 were positively associated with the prognosis of glioma patients, while LATS1/2 exhibited negative correlation with the glioma patient prognosis. Collectively, we deduce that, in glioma tissue context, MST1/2 may not be the essential component of the hippo/YAP pathway. Moreover, our findings uncover a new evidence supporting that YAP1/TAZ-BIRC5 might be abnormally activated due to LATS1/2 down-regulation, which in turn promote the occurrence and development of gliomas, paving the way to identify the potential therapeutic molecular target for gliomas. PMID- 27718126 TI - Suppression of CD26 inhibits growth and metastasis of pancreatic cancer. AB - CD26/DPPIV is a glycosylated transmembrane type II protein and has a multitude of biological functions, while its impact on the malignant phenotypes of cancer cells has not been fully understood. This study aimed to investigate the effect of CD26 on growth and metastasis of pancreatic cancer cells in vitro and in vivo. We found in this study that CD26 expression was higher in cell lines that derived from the metastatic sites than those from the primary tumor sites. In specimens of pancreatic cancer patients, CD26 expression was higher in cancerous tissues than in paired normal tissues. In in vitro experiments, knockdown of CD26 expression inhibited cell growth, migration, invasion, colony formation, and increased cell apoptosis of pancreatic cancer cells. Knockdown of CD26 also decreased tumor growth and liver metastasis in vivo by using xenograft animal models. Suppression of CD26 could inhibit expression of epithelial-mesenchymal transition (EMT) regulatory genes. Our results indicated that CD26 may represent a new therapeutic target for pancreatic cancer. PMID- 27718127 TI - Rab14 is overexpressed in ovarian cancers and promotes ovarian cancer proliferation through Wnt pathway. AB - The Rab GTPase family protein Rab14 has been implicated in cancer development. However, its clinical significance in ovarian cancers and its biological effects have not been examined. The present study aims to examine the clinical significance, biological roles, and molecular mechanism of Rab14 in ovarian cancer progression. We examined expression pattern of Rab14 in 122 cases of ovarian cancer specimens using immunohistochemistry and found Rab14 overexpression correlated with FIGO stage (p = 0.0041). We depleted Rab14 in SKOV3 cells using siRNA and overexpressed Rab14 in SW626 cells. Knockdown of Rab14 inhibited cell growth and invasion while its overexpression facilitated cell growth and invasion. In addition, Rab14 overexpression increased paclitaxel resistance in SW626 cells while its depletion reduced drug resistance. Then, we investigated the role of Rab14 in the regulation of WNT/beta-catenin signaling, demonstrating Rab14 overexpression regulated GSK3beta phosphorylation and nuclear beta-catenin accumulation. Rab14 depletion inhibited while its overexpression enhanced TCF transcriptional activity with corresponding change of Wnt target genes including MMP7 and c-myc. Wnt inhibitor abolished the effect of Rab14 on cell proliferation and Wnt target genes. In conclusion, the present study demonstrated that Rab14 promotes aggressiveness of ovarian cancer cell through, at least partly, Wnt signaling pathway. PMID- 27718129 TI - The readiness of emergency and trauma care in low- and middle-income countries: a cross-sectional descriptive study of 42 public hospitals in Albania. AB - BACKGROUND: Traumatic injuries have become a substantial but neglected epidemic in low- and middle-income countries (LMICs), but emergency rooms (ERs) in these countries are often staffed with healthcare providers who have minimal emergency training and experience. The aim of this paper was to describe the specialized training, available interventions, and the patient management strategies in the ERs in Albanian public hospitals. METHODS: A cross-sectional descriptive study of 42 ERs in the Republic of Albania between September 5, 2014, and December 29, 2014 was performed. Assessment subcategories included the following: (1) specialized training and/or certifications possessed by healthcare providers, (2) interventions performed in the ER, and (3) patient management strategies. RESULTS: Across the 42 ERs surveyed, less than half (37.1-42.5 %) of physicians and one third of nurses (7.1-26.0 %) working in the ERs received specialized trauma training. About half (47.9-57.1 %) of the ER physicians and one fifth of the nurses (18.3-22.9 %) possessed basic life support certification. This survey demonstrated some significant differences in the emergency medical care provided between primary, secondary, and tertiary hospitals across Albania (the significance level was set at 0.05). Specifically, these differences involved spinal immobilization (p = 0.01), FAST scan (p = 0.04), splinting (p = 0.01), closed reduction of displaced fractures (p = 0.02), and nurses performing cardiopulmonary resuscitation (CPR) (p = 0.01). Between 50.0 and 71.4 % of the facilities cited a combined lack of training and supplies as the reason for not offering interventions such as rapid sequence induction, needle thoracotomy, chest tube insertion, and thrombolysis. Mass casualty triage was utilized among 39.1 % primary hospitals, 41.7 % of secondary, and 28.6 % of tertiary. CONCLUSIONS: The emergency services in Albania are currently staffed with inadequately trained personnel, who lack the equipment and protocols to meet the needs of the population. PMID- 27718128 TI - Diverse roles of miR-335 in development and progression of cancers. AB - MicroRNAs (miRNAs), a series of small noncoding RNAs that regulate gene expression at the post-transcriptional/translational level, are pivotal in cell differentiation, biological development, occurrence, and development of diseases, especially in cancers. Early studies have shown that miRNA-335 (miR-335) is widely dysregulated in human cancers and play critical roles in tumorigenesis and tumor progression. In this review, we aim to summarize the regulation of miR-335 expression mechanisms in cancers. We focus on the target genes regulated by miR 335 and its downstream signaling pathways involved in the biological effects of tumor growth, invasion, and metastasis both in vitro and in vivo, and analyze the relationships between miR-335 expression and the clinical characteristics of tumors as well as its effects on prognosis. The collected evidences support the potential use of miR-335 in prognosis and diagnosis as well as the therapeutic prospects of miR-335 in cancers. PMID- 27718130 TI - Tissue reaction of deproteinized bovine bone matrix grafting in ectopic site: histological study on sheep. AB - The aim of this paper was to evaluate through histological analysis of the tissue reaction of deproteinized bovine bone matrix (DBBM) when inserted into the site of intramuscular ectopic sheep. In this study, 16 sheep received 3 groups and these were divided into 2 experimental times: Group 1-sham group, Group 2 particulate autogenous bone and Group 3-DBBM granules. All animals underwent surgical procedures for insertion of materials in an ectopic site (muscles of the lower back and after 3 and 6 months postoperatively, the samples were evaluated by histological analysis. The results indicated that the Sham group showed dense collagen fibers and thin, characterizing fibrosis at 3 and 6 months. In the autograft group there was a significant amount of collagen deposition and decreased inflammation at 6 months postoperatively. Group of DBBM, it was noted the presence of dense connective tissue and surrounding remaining particles was observed the formation of with osteoid characteristic tissue. The DBBM demonstrated biocompatibility, osteoconductivity and small osteogenesis capacity on ectopic site. PMID- 27718131 TI - The false academy: predatory publishing in science and bioethics. AB - This paper describes and discusses the phenomenon 'predatory publishing', in relation to both academic journals and books, and suggests a list of characteristics by which to identify predatory journals. It also raises the question whether traditional publishing houses have accompanied rogue publishers upon this path. It is noted that bioethics as a discipline does not stand unaffected by this trend. Towards the end of the paper it is discussed what can and should be done to eliminate or reduce the effects of this development. The paper concludes that predatory publishing is a growing phenomenon that has the potential to greatly affect both bioethics and science at large. Publishing papers and books for profit, without any genuine concern for content, but with the pretence of applying authentic academic procedures of critical scrutiny, brings about a worrying erosion of trust in scientific publishing.

PMID- 27718132 TI - The Therapy Attitudes and Process Questionnaire: A Brief Measure of Factors Related to Psychotherapy Appointment Attendance. AB - BACKGROUND: Patient non-attendance and dropout remains problematic in mental health settings. The theory of planned behavior (TPB) has proven useful in understanding such challenges in a variety of healthcare settings, but the absence of an adequate measure in mental health has hampered research in this area. OBJECTIVE: The aim of the current study was to develop and conduct an initial psychometric investigation of a brief measure, the Therapy Attitudes and Process Questionnaire (TAP), utilizing the TPB to understand factors associated with attendance in mental health settings. METHODS: We used a quantitative survey based design and administered the TAP to 178 adult participants who were engaged in individual or group psychotherapy. A subsample also provided data to assess validity and reliability. RESULTS: A four-factor solution was revealed through exploratory factor analysis and accounted for approximately 75 % of the variance in scores. Factors corresponded to those predicted by the TPB. Analyses supported the reliability, validity, and internal consistency of the measure. CONCLUSIONS: Results suggest that the TAP may be a useful tool for examining patients' attitudes and beliefs about attending psychotherapy appointments. The TAP can be used to better understand patients' intentions, attitudes, perceptions of behavioral control, and subjective norms relating to psychotherapy attendance. This understanding may facilitate improved outcomes for patients and clinicians. PMID- 27718134 TI - Postgastrectomy follow-up in the West: evidence base, guidelines, and daily practice. AB - Follow-up after gastrectomy for gastric cancer has several purposes, including management of side effects of surgery, oncological recurrence surveillance, psychological support, and data collection for research. How follow-up after gastrectomy, and especially recurrence surveillance, is performed differs immensely between different Western countries, despite guidelines from Western oncological organizations quite unanimously advocating symptom-driven surveillance, without scheduled cross-sectional imaging, endoscopies, or analysis of tumor markers. Given a complete lack of randomized data, the available body of observational data does not support intensive routine surveillance for recurrent disease. Moreover, studies of other cancers have shown a negative emotional impact of routine surveillance. There is an apparent need for randomized controlled trials to address the issue of optimized strategies for postgastrectomy recurrence surveillance. PMID- 27718135 TI - Mechanisms for the induction of gastric cancer by Helicobacter pylori infection: aberrant DNA methylation pathway. AB - Multiple pathogenic mechanisms by which Helicobacter pylori infection induces gastric cancer have been established in the last two decades. In particular, aberrant DNA methylation is induced in multiple driver genes, which inactivates them. Methylation profiles in gastric cancer are associated with specific subtypes, such as microsatellite instability. Recent comprehensive and integrated analyses showed that many cancer-related pathways are more frequently altered by aberrant DNA methylation than by mutations. Aberrant DNA methylation can even be present in noncancerous gastric mucosae, producing an "epigenetic field for cancerization." Mechanistically, H. pylori-induced chronic inflammation, but not H. pylori itself, plays a direct role in the induction of aberrant DNA methylation. The expression of three inflammation-related genes, Il1b, Nos2, and Tnf, is highly associated with the induction of aberrant DNA methylation. Importantly, the degree of accumulated aberrant DNA methylation is strongly correlated with gastric cancer risk. A recent multicenter prospective cohort study demonstrated the utility of epigenetic cancer risk diagnosis for metachronous gastric cancer. Suppression of aberrant DNA methylation by a demethylating agent was shown to inhibit gastric cancer development in an animal model. Induction of aberrant DNA methylation is the major pathway by which H. pylori infection induces gastric cancer, and this can be utilized for translational opportunities. PMID- 27718137 TI - Short-term surgical outcomes from a phase III study of laparoscopy-assisted versus open distal gastrectomy with nodal dissection for clinical stage IA/IB gastric cancer: Japan Clinical Oncology Group Study JCOG0912. AB - BACKGROUNDS: No confirmatory randomized controlled trials (RCTs) have evaluated the efficacy of laparoscopy-assisted distal gastrectomy (LADG) compared with open distal gastrectomy (ODG). We performed an RCT to confirm that LADG is not inferior to ODG in efficacy. METHODS: We conducted a multi-institutional RCT. Eligibility criteria included histologically proven gastric adenocarcinoma in the middle or lower third of the stomach, clinical stage I tumor. Patients were preoperatively randomized to ODG or LADG. This study is now in the follow-up stage. The primary endpoint is relapse-free survival (RFS) and the primary analysis is planned in 2018. Here, we compared the surgical outcomes of the two groups. This trial was registered at the UMIN Clinical Trials Registry as UMIN000003319. RESULTS: Between March 2010 and November 2013, 921 patients (LADG 462, ODG 459) were enrolled from 33 institutions. Operative time was longer in LADG than in ODG (median 278 vs. 194 min, p < 0.001), while blood loss was smaller (median 38 vs. 115 ml, p < 0.001). There was no difference in the overall proportion with in-hospital grade 3-4 surgical complications (3.3 %: LADG, 3.7 %: ODG). The proportion of patients with elevated serum AST/ALT was higher in LADG than in ODG (16.4 vs. 5.3 %, p < 0.001). There was no operation-related death in either arm. CONCLUSIONS: This trial confirmed that LADG was as safe as ODG in terms of adverse events and short-term clinical outcomes. LADG may be an alternative procedure in clinical IA/IB gastric cancer if the noninferiority of LADG in terms of RFS is confirmed. PMID- 27718136 TI - Global chemotherapy development for gastric cancer. AB - To combat the dismal mortality rates from metastatic gastric adenocarcinoma (GAC), new drugs and treatment strategies are needed. Today, metastatic GAC is predominantly treated by empiric chemotherapy. Combination of two cytotoxic agents has become commonplace in North America, Europe, and Asia. Human epidermal growth factor 2 (HER2) overexpression (protein or gene copy numbers) has resulted in the addition of trastuzumab in the first-line chemotherapy combination in patients whose tumor is HER2 positive. The addition of trastuzumab in this select population has provided a modest survival advantage. In this review we trace the global development of systemic therapy in patients with metastatic GAC and ponder what lies in the future. PMID- 27718138 TI - Stress test of a biological early warning system with zebrafish (Danio rerio). AB - The aim of this work was to develop a novel methodology to stress test the diagnostic capability of a video tracking system with zebrafish (Danio rerio), against two pre-established disturbances. Eight different treatments were tested varying the presence or absence of a toxicant (NaOCl) and two disturbances: the passing of a shadow (mimicking a predator) and entrapment of the fish. The concentration tested corresponded to a sublethal (1 % 24 h-LC50) and short term exposure (2 h). A total of 56 organisms were tested resulting in 112 diagnoses (before and after the contamination). A statistical model of diagnosis was developed using Self-organizing Map (SOM) and Correspondence Analysis (CA). Sensitivity, specificity, accuracy, false positive and false negative values were calculated to evaluate the diagnostic performance. The disturbances did not negatively affect the capability of the model. In the presence of at least one of these variables, the diagnostic performance was similar or even superior to the baseline results without disturbances. Furthermore, the system produced a large number of correct diagnoses, at an ecologically relevant concentration of exposure, in a non-invasive way. PMID- 27718139 TI - Feasibility and diagnostic performance of fractional flow reserve measurement derived from coronary computed tomography angiography in real clinical practice. AB - Non-invasive fractional flow reserve measured by coronary computed tomography angiography (FFRCT) has demonstrated a high diagnostic accuracy for detecting coronary artery disease (CAD) in selected patients in prior clinical trials. However, feasibility of FFRCT in unselected population have not been fully evaluated. Among 60 consecutive patients who had suspected significant CAD by coronary computed tomography angiography (CCTA) and were planned to undergo invasive coronary angiography, 48 patients were enrolled in this study comparing FFRCT with invasive fractional flow reserve (FFR) without any exclusion criteria for the quality of CCTA image. FFRCT was measured in a blinded fashion by an independent core laboratory. FFRCT value was evaluable in 43 out of 48 (89.6 %) patients with high prevalence of severe calcification in CCTA images [calcium score (CS) >400: 40 %, and CS > 1000: 19 %). Per-vessel FFRCT value showed good correlation with invasive FFR value (Spearman's rank correlation = 0.69, P < 0.001). The area under the receiver operator characteristics curve (AUC) of FFRCT was 0.87. Per-vessel accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were 68.6, 92.9, 52.4, 56.5, and 91.7 %, respectively. Even in eight patients (13 vessels) with extremely severely calcified lesions (CS > 1000), per-vessel FFRCT value showed a diagnostic performance similar to that in patients with CS <= 1000 (Spearman's rank correlation = 0.81, P < 0.001). FFRCT could be measured in the majority of consecutive patients who had suspected significant CAD by CCTA in real clinical practice and demonstrated good diagnostic performance for detecting hemodynamically significant CAD even in patients with extremely severe calcified vessels. PMID- 27718140 TI - Prediction of clinical outcome by myocardial CT perfusion in patients with low risk unstable angina pectoris. AB - The prognostic implications of myocardial computed tomography perfusion (CTP) analyses are unknown. In this sub-study to the CATCH-trial we evaluate the ability of adenosine stress CTP findings to predict mid-term major adverse cardiac events (MACE). In 240 patients with acute-onset chest pain, yet normal electrocardiograms and troponins, a clinically blinded adenosine stress CTP scan was performed in addition to conventional diagnostic evaluation. A reversible perfusion defect (PD) was found in 38 patients (16 %) and during a median follow up of 19 months (range 12-22 months) 25 patients (10 %) suffered a MACE (cardiac death, non-fatal myocardial infarction and revascularizations). Accuracy for the prediction of MACE expressed as the area under curve (AUC) on receiver-operating characteristic curves was 0.88 (0.83-0.92) for visual assessment of a PD and 0.80 (0.73-0.85) for stress TPR (transmural perfusion ratio). After adjustment for the pretest probability of obstructive coronary artery disease, both detection of a PD and stress TPR were significantly associated with MACE with an adjusted hazard ratio of 39 (95 % confidence interval 11-134), p < 0.0001, for visual interpretation and 0.99 (0.98-0.99) for stress TPR, p < 0.0001. Patients with a PD volume covering >10 % of the LV myocardium had a worse prognosis compared to patients with a PD covering <10 % of the LV myocardium, p = 0.0002. The optimal cut-off value of the myocardial PD extent to predict MACE was 5.3 % of the left ventricle [sensitivity 84 % (64-96), specificity 95 % (91-97)]. Myocardial CT perfusion parameters predict mid-term clinical outcome in patients with recent acute-onset chest pain. PMID- 27718141 TI - Promoting interdomain analogical transfer: When creating a problem helps to solve a problem. AB - Research on analogical thinking has devised several ways of promoting an abstract encoding of base analogs, thus rendering them more retrievable during later encounters with similar situations lacking surface similarities. Recent studies have begun to explore ways of facilitating transfer at retrieval time, which could facilitate the retrieval of distant analogs learned within contexts that were not specially directed to emphasize their abstract structure. Such studies demonstrate that comparing a target problem to an analogous problem helps students retrieve base analogs that lack surface similarities. To devise more portable ways of enhancing analogical transfer, Experiment 1 replicated Kurtz and Loewenstein's (Memory & Cognition, 35, 334-341, 2007) target-comparison procedure with an additional condition in which participants compared the target to a nonanalogous problem before attempting to reach its solution. Although comparing two analogous targets outperformed the standard transfer condition in promoting analogical transfer, comparing nonanalogous problems did not yield a transfer advantage. Based on prior studies that showed that the activity of creating analogous problems during their initial encoding elicits a more abstract representation of base analogs, in Experiment 2 we assessed whether constructing a second analogous target problem at retrieval time helps participants retrieve superficially dissimilar base analogs. As predicted, target invention increased the retrieval of distant sources. In both experiments we found an association between the quality of the generated schemas and the probability of retrieving a distant base analog from memory. PMID- 27718142 TI - The effect of anomalous utterances on language production. AB - Speakers sometimes encounter utterances that have anomalous linguistic features. Are such features registered during comprehension and transferred to speakers' production systems? In two experiments, we explored these questions. In a syntactic-priming paradigm, speakers heard prime sentences with novel or intransitive verbs as part of prepositional-dative or double-object structures (e.g., The chef munded the cup to the burglar or The doctor existed the pirate the balloon). Speakers then described target pictures eliciting the same structures, using the same or different novel or intransitive verbs. Speakers overall described targets with the same structures as the primes (abstract syntactic priming), but more so when the primes and targets had the same novel or intransitive verbs (a lexical boost), an effect that was only observed when the novel words served as the verbs in both the prime and target sentences. Such a lexical boost could only manifest if speakers formed associations between the verbs and structures in the primes during comprehension, and if these associations were then transferred to their production systems. We thus showed that anomalous utterance features are not ignored but persist (at least) in speakers' immediately subsequent production. PMID- 27718143 TI - Concentration of Donepezil in the Cerebrospinal Fluid of AD Patients: Evaluation of Dosage Sufficiency in Standard Treatment Strategy. AB - Although some studies have described the pharmacokinetics and pharmacodynamics of donepezil in the peripheral compartment, studies focused on drug transport across the blood-brain barrier are still very rare. To our knowledge, the fluctuation in the cerebrospinal fluid concentration of donepezil after administration of the drug has not been described in the literature so far. We recruited 16 patients regularly taking a standard therapeutic dose of donepezil (10 mg per day). All patients (Caucasian race) were treated for at least three months with a stable dose of 10 mg per day prior to sample collection. Patients were divided into two groups depending on the time of plasma and cerebrospinal fluid sampling: 12 h (n = 9; 4 M/5F aged 78.68 +/- 7.35 years) and 24 h (n = 7; 3 M/4F aged 77.14 +/- 5.87 years) after donepezil administration. The cerebrospinal fluid sample was collected by standard lumbar puncture technique using a single-use traumatic needle. The samples were analysed on an Agilent 1260 Series liquid chromatograph comprising a degasser, a quaternary pump, a light-tight autosampler unit set, a thermostated column compartment, and a UV/VIS detector. Agilent ChemStation software, the statistical software Prism4, version 5.0 (GraphPad Software, USA), and IBM(r) SPSS(r) Statistics were used for the analysis of the results. The difference in plasma concentration of donepezil after 12 h (mean +/- SEM; 39.99 +/- 5.90 ng/ml) and after 24 h (29.38 +/- 1.71 ng/ml) was nonsignificant. In contrast, the donepezil concentration in the cerebrospinal fluid was significantly higher in the 24-h interval (7.54 +/- 0.55 ng/ml) compared with the 12-h interval (5.19 +/- 0.83 ng/ml, which is ~70 % based on mean cerebrospinal fluid values). Based on these data, it is plausible to predict that donepezil might produce a stronger AChE inhibition in the brain at 24 h compared with 12 h following the administration. This information may help physicians individually adjust the time of drug administration in the patients according to time course of the disease symptoms. PMID- 27718144 TI - Cardiomyopathy as presenting sign of glycogenin-1 deficiency-report of three cases and review of the literature. AB - We describe a new type of cardiomyopathy caused by a mutation in the glycogenin-1 gene (GYG1). Three unrelated male patients aged 34 to 52 years with cardiomyopathy and abnormal glycogen storage on endomyocardial biopsy were homozygous for the missense mutation p.Asp102His in GYG1. The mutated glycogenin 1 protein was expressed in cardiac tissue but had lost its ability to autoglucosylate as demonstrated by an in vitro assay and western blot analysis. It was therefore unable to form the primer for normal glycogen synthesis. Two of the patients showed similar patterns of heart dilatation, reduced ejection fraction and extensive late gadolinium enhancement on cardiac magnetic resonance imaging. These two patients were severely affected, necessitating cardiac transplantation. The cardiomyocyte storage material was characterized by large inclusions of periodic acid and Schiff positive material that was partly resistant to alpha-amylase treatment consistent with polyglucosan. The storage material had, unlike normal glycogen, a partly fibrillar structure by electron microscopy. None of the patients showed signs or symptoms of muscle weakness but a skeletal muscle biopsy in one case revealed muscle fibres with abnormal glycogen storage. Glycogenin-1 deficiency is known as a rare cause of skeletal muscle glycogen storage disease, usually without cardiomyopathy. We demonstrate that it may also be the cause of severe cardiomyopathy and cardiac failure without skeletal muscle weakness. GYG1 should be included in cardiomyopathy gene panels. PMID- 27718146 TI - Microbial interactions with chromium: basic biological processes and applications in environmental biotechnology. AB - Chromium (Cr) is a highly toxic metal for microorganisms as well as plants and animal cells. Due to its widespread industrial use, Cr has become a serious pollutant in diverse environmental settings. The hexavalent form of the metal, Cr(VI), is considered a more toxic species than the relatively innocuous and less mobile Cr(III) form. The study of the interactions between microorganisms and Cr has been helpful to unravel the mechanisms allowing organisms to survive in the presence of high concentrations of Cr(VI) and to detoxify and remove the oxyanion. Various mechanisms of interactions with Cr have been identified in diverse species of bacteria and fungi, including biosorption, bioaccumulation, reduction of Cr(VI) to Cr(III), and chromate efflux. Some of these systems have been proposed as potential biotechnological tools for the bioremediation of Cr pollution using bioreactors or by in situ treatments. In this review, the interactions of microorganisms with Cr are summarised, emphasising the importance of new research avenues using advanced methodologies, including proteomic, transcriptomic, and metabolomic analyses, as well as the use of techniques based on X-ray absorption spectroscopy and electron paramagnetic resonance spectroscopy.

Qingling was identified as Morchella crassipes Mes-20 by using nuclear ribosomal DNA internal transcribed spacer phylogeny. It was inoculated into sweet corn to observe colonized roots in purified culture and in greenhouse experiments. The elongation and maturation zones of sweet corn were remarkably colonized at the cortex intercellular and intracellular cells, vessel cells, and around the Casparian strip, forming ectendomycorrhiza-like structures. Colonization was also observed in the zone of cell division proximal to the root cap. Greenhouse assays with sweet corn showed that this morel stimulated the development of the root system and significantly increased the dry root biomass. M. crassipes also significantly reduced the incidence of Fusarium verticillioides in the kernels of mature ears when inoculated into young ears before Fusarium inoculation and prevented Fusarium infection in corn ears compared with that of the control in the greenhouse. When grown under axenic conditions, M. crassipes produced the phytohormones abscisic acid, indole-3-acetic acid, and salicylic acid. The benefits to plants elicited by M. crassipes may result from these phytohormones which may improve the drought resistance, biomass growth and resistance to Fusarium.

AB - Morphological engineering techniques have recently gained popularity as they are used for increasing the productivity of a variety of metabolites and enzymes in fungi growing in submerged cultures. Their action is mainly associated with the changes they evoke in fungal morphology. Traditional morphological engineering approaches include manipulation of spore concentration, pH-shifting and mechanical stress exerted by stirring and aeration. As the traditional methods proved to be insufficient, modern techniques such as changes of medium osmolality or addition of mineral microparticles to the media (microparticle-enhanced cultivation, MPEC) were proposed. Despite the fact that this area of knowledge is still being developed, there are a fair amount of scientific articles concerning the cultivations of filamentous fungi with the use of these techniques. It was described that in Ascomycetes fungi both MPEC or change of osmolality successfully led to the change of mycelial morphology, which appeared to be favorable for increased productivity of secondary metabolites and enzymes. There are also limited but very promising reports involving the successful application of MPEC with Basidiomycetes species. Despite the fact that the mineral microparticles behave differently for various microorganisms, being strain and particle specific, the low cost of its application is a great benefit. This paper reviews the application of the modern morphology engineering techniques. The authors critically assess the advantages, shortcomings, and future prospects of their application in the cultivation of fungi. PMID- 27718145 TI - Newborn screening for mucopolysaccharidoses: a pilot study of measurement of glycosaminoglycans by tandem mass spectrometry. AB - BACKGROUND: Mucopolysaccharidoses (MPS) are a group of inborn errors of metabolism that are progressive and usually result in irreversible skeletal, visceral, and/or brain damage, highlighting a need for early diagnosis. METHODS: This pilot study analyzed 2862 dried blood spots (DBS) from newborns and 14 DBS from newborn patients with MPS (MPS I, n = 7; MPS II, n = 2; MPS III, n = 5). Disaccharides were produced from polymer GAGs by digestion with chondroitinase B, heparitinase, and keratanase II. Heparan sulfate (0S, NS), dermatan sulfate (DS) and mono- and di-sulfated KS were measured by liquid chromatography tandem mass spectrometry (LC-MS/MS). Median absolute deviation (MAD) was used to determine cutoffs to distinguish patients from controls. Cutoffs were defined as median + 7* MAD from general newborns. RESULTS: The cutoffs were as follows: HS-0S > 90 ng/mL; HS-NS > 23 ng/mL, DS > 88 ng/mL; mono-sulfated KS > 445 ng/mL; di-sulfated KS > 89 ng/mL and ratio di-KS in total KS > 32 %. All MPS I and II samples were above the cutoffs for HS-0S, HS-NS, and DS, and all MPS III samples were above cutoffs for HS-0S and HS-NS. The rate of false positives for MPS I and II was 0.03 % based on a combination of HS-0S, HS-NS, and DS, and for MPS III was 0.9 % based upon a combination of HS-0S and HS-NS. CONCLUSIONS: Combination of levels of two or more different GAGs improves separation of MPS patients from unaffected controls, indicating that GAG measurements are potentially valuable biomarkers for newborn screening for MPS. PMID- 27718149 TI - The Topology Prediction of Membrane Proteins: A Web-Based Tutorial. AB - There is a great need for development of educational materials on the transfer of current bioinformatics knowledge to undergraduate students in bioscience departments. In this study, it is aimed to prepare an example in silico laboratory tutorial on the topology prediction of membrane proteins by bioinformatics tools. This laboratory tutorial is prepared for biochemistry lessons at bioscience departments (biology, chemistry, biochemistry, molecular biology and genetics, and faculty of medicine). The tutorial is intended for students who have not taken a bioinformatics course yet or already have taken a course as an introduction to bioinformatics. The tutorial is based on step-by step explanations with illustrations. It can be applied under supervision of an instructor in the lessons, or it can be used as a self-study guide by students. In the tutorial, membrane-spanning regions and alpha-helices of membrane proteins were predicted by internet-based bioinformatics tools. According to the results achieved from internet-based bioinformatics tools, the algorithms and parameters used were effective on the accuracy of prediction. The importance of this laboratory tutorial lies on the facts that it provides an introduction to the bioinformatics and that it also demonstrates an in silico laboratory application to the students at natural sciences. The presented example education material is applicable easily at all departments that have internet connection. This study presents an alternative education material to the students in biochemistry laboratories in addition to classical laboratory experiments. PMID- 27718150 TI - Randomized clinical trial to comparing efficacy of daily, weekly and monthly administration of vitamin D3. AB - The comparative efficacy and safety profiles of selected daily 1000 IU, weekly 7000 IU and monthly 30,000 IU vitamin D 3-not previously investigated-will be evaluated. Here, a prospective, randomized clinical trial, comparing efficacy and safety of a daily single dose of 1000 IU (group A) to a once-weekly 7000 IU dose (group B), or monthly 30,000 IU dose (group C) of vitamin D3. The present study is a controlled, randomized, open-label, multicenter clinical trial, 3 months in duration. Sixty-four adult subjects with vitamin D deficiency (25OHD<20 ng/ml), were included according to the inclusion and exclusion criteria. Dose-responses for increases in serum vitamin 25OHD were statistically equivalent for each of the three groups: A, B and C. Outcomes were 13.0 +/- 1.5; 12.6 +/- 1.1 and 12.9 +/- 0.9 ng/ml increases in serum 25OHD per 1000 IU, daily, weekly and monthly, respectively. The treatment of subjects with selected doses restored 25OHD values to levels above 20 ng/ml in all groups. Treatment with distinct administration frequency of vitamin D3 did not exhibit any differences in safety parameters. The daily, weekly and monthly administrations of daily equivalent of 1000 IU of vitamin D3 provide equal efficacy and safety profiles. PMID- 27718151 TI - Surgical Outcomes for the Ruptured Hepatocellular Carcinoma: Multicenter Analysis with a Case-Controlled Study. AB - BACKGROUND: While spontaneously ruptured hepatocellular carcinoma (HCC) has a poor prognosis, the true impact of a rupture on survival after hepatic resection is unclear. METHODS: Fifty-eight patients with ruptured HCC and 1922 with non ruptured HCC underwent hepatic resection between 2000 and 2013. To correct the difference in the clinicopathological factors between the two groups, propensity score matching (PSM) was used at a 1:1 ratio, resulting in a comparison of 42 patients/group. We investigated outcomes in all patients with ruptured HCC and compared outcomes between the two matched groups. RESULTS: Of the 58 patients with ruptured HCC, 7 patients (13 %) died postoperatively. Overall survival (OS) rate at 5 years after hepatic resection was 37 %. Emergency hepatic resection was an independent risk factor for in-hospital death and Child-Pugh class B for unfavorable OS in multivariate analysis. Clinicopathological variables were well balanced between the two groups after PSM. No significant differences were noted in incidence of in-hospital death (ruptured HCC 12 % vs non-ruptured HCC 2 %, p = 0.202) or OS rate (5/10-year; 42 %/38 % vs 67 %/30 %, p = 0.115). CONCLUSION: Emergency hepatic resection should be avoided for ruptured HCC in Child-Pugh class B patients. Rupture itself was not a risk for unfavorable surgical outcomes. PMID- 27718153 TI - Effect of adaptive replanning in patients with locally advanced nasopharyngeal carcinoma treated by intensity-modulated radiotherapy: a propensity score matched analysis. AB - PURPOSE: Limited data have been published regarding the effect of adaptive radiotherapy (ART) on clinical outcome in patients with nasopharyngeal carcinoma (NPC). We compared the long-term outcomes in patients with locally advanced NPC treated by adaptive intensity-modulated radiotherapy (IMRT) replanning versus IMRT. METHODS: 200 NPC patients with stage T3/T4 were included between October 2004 and November 2010. Patients in both treatment groups were matched using propensity score matching method at the ratio of 1:1. Clinical outcomes were analyzed with Kaplan-Meier method, log-rank test and Cox regression. RESULTS: After matching, 132 patients (66 patients in each group) were included for analysis. The median follow-up for the IMRT replanning group was 70 months, while the IMRT group was 69 months. The 5-year local-regional recurrence-free survival (LRFS) rate was higher in IMRT replanning group (96.7 vs. 88.1 %, P = 0.022). No significant differences in distant metastasis-free survival (DMFS), progression free survival (PFS) and overall survival (OS) were observed between the two groups. 21.2 % patients in IMRT replanning group and 28.8 % patients in IMRT group had distant metastasis. In multivariable analysis, IMRT replanning was identified as an independent prognostic factor for LRFS (hazard ratio 0.229; 95 % CI 0.062-0.854; P = 0.028), but not for DMFS, PFS and OS. CONCLUSIONS: IMRT replanning provides an improved LRFS for stage T3/T4 NPC patients compared with IMRT. Distant metastasis remains the main pattern of treatment failure. No significant advantage was observed in DMFS, PFS and OS when adaptive replanning was used. PMID- 27718152 TI - Differential BMI1, TWIST1, SNAI2 mRNA expression pattern correlation with malignancy type in a spectrum of common cutaneous malignancies: basal cell carcinoma, squamous cell carcinoma, and melanoma. AB - PURPOSE: Melanoma, squamous cell carcinoma (SCC), and basal cell carcinoma (BCC) can be used as a unique model to identify molecular mechanisms to distinguish rarely metastatic (BCC), often metastatic (SCC) and most metastatic (melanoma) cancer. It is known that epithelial-mesenchymal transition and stemness transcription factors (TWIST1, SNAI2/SLUG, and BMI1) play an important role in metastasis and their dysregulation has been demonstrated in metastatic cancers. We hypothesized that this spectrum of cutaneous cancers (BCC, SCC, and melanoma) would be a unique cancer model system to elucidate steps toward cancer invasion and metastasis. METHODS: We evaluated the mRNA expression level of BMI1, TWIST1, and SNAI2/SLUG and studied clinicopathological features in 170 skin cancers along with normal tissue samples. RESULTS: We demonstrate downregulation of BMI1 mRNA expression in BCC samples compared with controls (p = 0.0001), SCC (p = 0.001), and melanoma (p = 0.0001) samples. Downregulation of TWIST1 mRNA expression is seen in only BCC samples compared with controls (p = 0.031). High SNAI2 mRNA expression is represented in melanoma samples compared with controls (p = 0.022) and SCC samples (p = 0.031). High mRNA expression of TWIST1 is seen in patients with positive history of cancers. Extremely low mRNA expression of BMI1 is detected in patients with positive history of cancers other than skin cancer. CONCLUSIONS: These findings provide support for the hypothesis that the spectrum of cutaneous cancers could be better understood as a series of gene dosage dependent entities with distinct molecular events. Oncogene-induced senescence, mechanism of which is still unclear, could be one explanation for these results. PMID- 27718154 TI - Prognostic significance of immune cells in the tumor microenvironment and peripheral blood of gallbladder carcinoma patients. AB - BACKGROUND: The role of the interaction between tumor cells and inflammatory cells in gallbladder carcinoma (GBC) is unclear. Inflammatory cells exist in both the tumor immune microenvironment and the host peripheral blood circulatory system. In the current study, we examined the prognostic value of inflammatory cells in the tumor microenvironment and peripheral blood in patients with GBC. METHODS: 98 patients with GBC were recruited in this retrospective study. Using immunohistochemistry, we examined tumor-infiltrating CD3+ generic T-cells, CD8+ cytotoxic T-cells, CD45RO+ memory T-cells, and CD15+ neutrophils. Peripheral venous blood samples were also collected, and absolute neutrophil count (ANC), absolute lymphocyte count (ALC) and neutrophil/lymphocyte ratio (NLR) were measured. The relationships between these variables and patient outcome were evaluated. RESULTS: Survival analysis revealed that the density of CD3+ cell infiltrates in the tumor microenvironment was positively correlated with overall survival (OS) and the density of CD15+ cell infiltrates was negatively correlated with the OS. The combined analysis showed that a high density of CD3+ cell infiltrates combined with a low density of CD15+ cell infiltrates was an independent prognostic factor for GBC. In peripheral blood, survival analysis suggested that ANC and NLR were negatively correlated, while ALC was positively correlated with OS. Multivariate survival analysis showed that NLR was an independent prognostic factor for gallbladder cancer prognosis. CONCLUSIONS: The results indicate that the combination of high density of CD3+ cell infiltrates combined with a low density of CD15+ cell infiltrates in tumor samples and pretreatment peripheral blood NLR were independent prognostic factors in patients with GBC. PMID- 27718155 TI - Effectiveness and safety of aflibercept for metastatic colorectal cancer: retrospective review within an early access program in Spain. AB - PURPOSE: In the VELOUR study, aflibercept + FOLFIRI regimen resulted in improved survival in metastatic colorectal cancer (mCRC) patients who progressed after oxaliplatin. The use of aflibercept outside the clinical trial framework needs to be further assessed in terms of effectiveness and tolerability. METHODS: Early access to aflibercept through a named patient programme (NPP) was provided to mCRC patients receiving FOLFIRI as second-line treatment in Spain. The effectiveness of aflibercept was assessed as progression-free survival (PFS) achieved within the NPP population. Post hoc analyses on PFS were done according to certain baseline characteristics (K-RAS mutation, prior targeted therapy) or prognostic factors. RESULTS: Registries from 71 mCRC patients included in the NPP were reviewed retrospectively. The median age for the NPP population was 64 years (19.7 % aged >=70 years) and 63.4 % patients had >=2 metastases. A median PFS of 5.3 months (95 % CI, 3.6-8.5 months) was achieved, which did not depend on K-RAS mutation status or prior targeted therapy received. The risk of progression or death increased in patients with a poor prognosis as per the GERCOR score (performance status [PS] 1-2 and increased baseline lactate dehydrogenase [LDH] level) compared with patients with a good prognosis (PS 0 and normal LDH level) (median PFS: 2.6 vs. 8.3 months, respectively; p = 0.0124). Aflibercept was well tolerated, with a manageable toxicity profile. CONCLUSIONS: Bearing in mind the differences in sample size, the PFS achieved with the aflibercept + FOLFIRI regimen in the real-life practice setting is comparable to that observed in the clinical trial setting. PMID- 27718156 TI - Patient-derived xenografts for childhood solid tumors: a valuable tool to test new drugs and personalize treatments. AB - The use of preclinical models is essential in translational cancer research and especially important in pediatric cancer given the low incidence of each particular type of cancer. Cell line cultures have led to significant advances in cancer biology. However, cell lines have adapted to growth in artificial culture conditions, thereby undergoing genetic and phenotypic changes which may hinder the translational application. Tumor grafts developed in mice from patient tumor tissues, generally known as patient-derived xenografts (PDXs), are interesting alternative approaches to reproducing the biology of the original tumor. This review is focused on highlighting the interest of PDX models in pediatric cancer research and supporting strategies of personalized medicine. This review provides: (1) a description of the background of PDX in cancer, (2) the particular case of PDX in pediatric cancer, (3) how PDX can improve personalized medicine strategies, (4) new methods to increase engraftment, and, finally, (5) concluding remarks. PMID- 27718157 TI - New clinical trials regulation in Spain: analysis of royal decree 1090/2015. AB - The coming into force of Directive 2001/20/EC represented a step forward in harmonising clinical trial regulation in European countries, guaranteeing a uniform protection of subjects participating in clinical research across Europe. However, it led to a disproportionate increase in the bureaucratization, and thus, it became evident that procedures needed to be simplified without detriment to patient's safety. Thus, Regulation 536/2014, that repealed Directive 2001/20/EC, with the aim of decreasing the growing bureaucratization and stimulating clinical research in Europe, established simplified procedures, such as regulating a common procedure for authorising trials in Europe, the institution of strict assessment timelines, or the definition of new concepts, such as "low-intervention clinical trial". The legal form of a Regulation allowed the norm to be directly applied to Member States without the need for transposition. By means of the new Royal Decree, the national legislation is adapted to make the application of the regulation feasible and it allows the development of the aspects that the Regulation leaves to national legislation. Both documents seek to stimulate clinical research with medicinal products to foster knowledge, facilitate transparency, and reinforce subjects' safety. This will surely be the case, but with this revision, we will look at the novelties and key aspects that are most relevant to investigators and we will analyse the consequences for all parties involved in clinical research. PMID- 27718158 TI - Perceptions of Oncologists, Healthcare Policy Makers, Patients and the General Population on the Value of Pharmaceutical Treatments in Oncology. AB - INTRODUCTION: The purpose of this study was to explore the main factors explaining the relative weight of the different attributes that determine the value of oncologic treatments from the different perspectives of healthcare policy makers (HCPM), oncologists, patients and the general population in Spain. METHODS: Structured interviews were conducted to assess: (1) the importance of the attributes on treatment choice when comparing a new cancer drug with a standard cancer treatment; (2) the importance of survival, quality of life (QoL), costs and innovation in cancer; and (3) the most worrying side effects related to cancer drugs. RESULTS: A total of 188 individuals participated in the study. For all participants, when choosing treatments, the best rated characteristics were greater efficacy, greater safety, treatment adaptation to patients' individual requirements and the rapid reincorporation of patients to their daily activities. There were important differences among participants in their opinion about survival, QoL and cost. In general, oncologists, patients, and the general population gave greater value to gains in QoL than healthcare policy makers. Compared to other participants healthcare policy makers gave greater importance to the economic impact related to oncology treatments. CONCLUSIONS: Gains in QoL, survival, safety, cost and innovation are perceived differently by different groups of stakeholders. It is recommended to consider the perspective of different stakeholders in the assessment of a new cancer drugs to obtain more informed decisions when deciding on the most appropriate treatment to use.

AB - The homeostatic controls over eating are inextricably linked to the reward aspects of eating. The result is an integrated response that coordinates the internal milieu with the prevailing environment. Thus, appetite, which reflects a complex interaction among the external environment, behavioral profile, and subjective states as well as the storage and metabolism of energy, has an important role in the regulation of energy balance. In the prevailing food environment which offers an abundance of food choices it is likely that the motivation to consume from a wide range of delectable foods plays a greater role in contributing to overeating than in the past when the motivation to eat was largely governed by metabolic need. The response to food-related cues can promote strong desires to eat known as cravings by activating the mesocorticolimbic dopamine neurocircuitry. Cravings are associated with subsequent eating and weight-related outcomes. Being able to control food cravings is a determinant of success at adhering to an energy-restricted diet regimen. Increased understanding of the neurocircuitry of appetite regulation, especially reward-related eating behavior, has provided potential targets for therapeutic anti-obesity agents specifically directed at reward mechanisms. The naltrexone-bupropion combination and lorcaserin, which are both approved by the US Food and Drug Administration (FDA) for long-term weight management, have shown promise in addressing craving related eating behavior. Phentermine and liraglutide are approved as monotherapies for weight management. Preliminary research suggests that liraglutide, as well as phentermine alone or in combination with lorcaserin, may be effective in targeting food cravings. Food components such as thylakoid membranes have also been shown to influence food cravings. This review explores the concepts related to appetite and reward-induced eating behavior, as well as the pharmacological options and food-derived components that may be used to address food cravings. PMID- 27718161 TI - HIV Immune Recovery Inflammatory Syndrome and Central Nervous System Paracoccidioidomycosis. AB - The immune reconstitution inflammatory syndrome (IRIS) is a deregulated inflammatory response to invading microorganisms. It is manifested when there is an abrupt change in host immunity from an anti-inflammatory and immunosuppressive state to a pro-inflammatory state as a result of rapid depletion or removal of factors that promote immune suppression or inhibition of inflammation. The aim of this paper is to discuss and re-interpret the possibility of association of paracoccidioidomycosis (PCM) with IRIS in the central nervous system (CNS) in a case from Brazil published by Silva-Vergara ML. et al. (Mycopathologia 177:137 141, 6). An AIDS patient who was not receiving medical care developed pulmonary PCM successfully treated with itraconazole. The patient developed central nervous system PCM (NPCM) after starting the ARV therapy with recovery of immunity and control of HIV viral load, although it was not interpreted as IRIS by the authors, it fulfills the criteria for CNS IRIS. This could be the first case of NPCM associated with IRIS described. Although not frequent, IRIS must be considered in PCM patients and HIV, from endemic areas or patients that traveled to endemic areas, receiving ARV treatment and with worsening symptoms. PMID- 27718160 TI - Reappraisal of Conventional Diagnosis for Dermatophytes. AB - Dermatophytoses include a wide variety of diseases involving glabrous skin, nails and hair. These superficial infections are a common cause of consultation in dermatology. In many cases, their diagnosis is not clinically obvious, and mycological analysis therefore is required. Direct microscopic examination of the samples using clearing agents provides a quick response to the clinician and is usually combined with cultures on specific media, which must be used to overcome the growth of contaminating moulds that may hamper the recovery of dermatophytes. Accurate identification of the causative agent (i.e. at the species level), currently based on morphological criteria, is necessary not only to initiate an appropriate treatment but also for setting prophylactic measures. However, conventional methods often lack sensitivity and species identification may require up to 4 weeks if subcultures are needed. Histological analysis, which is considered the "gold standard" for the diagnosis of onychomycoses, is seldom performed, and as direct examination, it does not allow precise identification of the pathogen. Nevertheless, a particular attention to the quality of clinical specimens is warranted. Moreover, the sensitivity of direct examination may be greatly enhanced by the use of fluorochromes such as calcofluor white. Likewise, sensitivity of the cultures could be enhanced by the use of culture media containing antifungal deactivators. With the generalization of molecular identification by gene sequencing or MALDI-TOF mass spectrometry, the contribution of historical biochemical or physiological tests to species identification of atypical isolates is now limited. Nevertheless, despite the recent availability of several PCR-based kits and an extensive literature on molecular methods allowing the detection of fungal DNA or both detection and direct identification of the main dermatophyte species, the biological diagnosis of dermatophytosis in 2016 still relies on both direct examination and cultures of appropriate clinical specimens. PMID- 27718162 TI - Impact of the Use of Regional Poison Control Centers in an Urban EMS Dispatch System. AB - BACKGROUND: The public commonly calls 911 for unintentional ingestions, rather than calling the local poison center. By utilizing a series of scripted questions, 911 dispatchers in Los Angeles determine if an ingestion meets "omega 1" classification. Under such circumstances, the regional poison center is contacted prior to dispatch of paramedics. If the poison center advises that the patient can remain at home, EMS is not dispatched and the patient is followed at home by the poison center. The primary objective is to determine the number of averted transports through involvement of a poison center. A secondary objective is to determine the potential costs and charges saved with the use of such a strategy. METHODS: A retrospective review of all overdose calls with an "omega-1" classification to a single EMS system between 1/2008-6/2012. Each call culminating in an EMS dispatch was subsequently reviewed by two additional reviewers. The cost savings was determined by utilizing data from the Medical Expenditure Panel Survey (MEPS) from 2000 to 2010. Monetary values were adjusted to 2012 dollars. RESULTS: Three hundred eighteen cases received "omega-1" dispatch classification. EMS was dispatched 19 times (5.98 %), and 11 patients (3.46 %) were ultimately transported. The most common reasons for transport were ambiguity over the ingested agent or amount, and caller insistence. Using these estimates, routine consultation of a regional poison center as part of EMS dispatch averted $486,595 in charges, and $183,279 in payments. CONCLUSIONS: Routine consultation of a poison center by emergency medical dispatchers can reduce unnecessary dispatches, ambulance transports, and ED visits with significant associated cost savings. PMID- 27718163 TI - Hydrocodone Bitartrate ER (Hysingla(r) ER): A Review in Chronic Pain. AB - Hydrocodone bitartrate extended-release (Hysingla(r) ER; referred to hereafter as hydrocodone ER) was the first single-entity hydrocodone formulation recognized by the US FDA as having abuse-deterrent properties. It is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Once daily oral hydrocodone ER provides consistent plasma hydrocodone concentrations and sustained analgesia over the 24-h dosing interval. Its physicochemical properties render hydrocodone ER harder to manipulate physically, which is expected to deter intranasal, intravenous and oral abuse. For instance, oral hydrocodone ER (intact or chewed) significantly reduced drug liking relative to hydrocodone solution in a clinical study. In two large phase III studies in patients with chronic pain, hydrocodone ER reduced pain intensity, with its effects seen early (during dose titration) and maintained during <=76 weeks' treatment. During maintenance therapy, the majority of patients continued hydrocodone ER at the dosage achieved at the end of dose titration and without requiring increased doses of supplemental pain medication, suggesting adequate pain management. Hydrocodone ER was generally well tolerated, with a safety profile consistent with that seen with other MU-opioid analgesics. However, like other opioids, it is associated with risks of addiction, abuse/misuse and serious adverse events (AEs), including respiratory depression, withdrawal, physical dependence and overdose. Although large postmarketing studies are needed to determine whether the abuse-deterrent properties of hydrocodone ER result in meaningful reductions in abuse, misuse and related adverse clinical outcomes, current evidence indicates that hydrocodone ER is a useful treatment option for patients with chronic pain.

The Impact on Subject Examination Scores of Changing a Neuropsychiatry Clerkship to Independent Clerkships in Psychiatry and Neurology. AB - OBJECTIVE: This study was undertaken to assess any impact on National Board of Medical Examiners (NBME) neurology and psychiatry subject examination scores of changing from an integrated neuropsychiatry clerkship to independent neurology and psychiatry clerkships. METHODS: NBME psychiatry and neurology subject examinations scores were compared for all 625 students completing the required neuropsychiatry clerkship in academic years 2005-2006 through 2008-2009 with all 650 students completing the independent neurology and psychiatry clerkships in academic years 2009-2010 through 2012-2013. Statistical adjustments were made to ensure comparability across groups and over time. RESULTS: A significant improvement in subject examination scores was associated with the independent clerkships. CONCLUSIONS: The independent clerkship model was associated with a modest improvement in NBME subject examination scores. This finding may be attributable to many causes or combination of causes other than curricular design. Curricular planners need to pay attention to the potential impact of course integration on specialty-specific NBME subject examination performance. PMID- 27718164 TI - The Diagnostic and Prognostic Potential of microRNAs in Epithelial Ovarian Carcinoma. AB - Ovarian cancer causes more than 100,000 deaths globally per year. Despite intensive research efforts, there has been little improvement in the overall survival of patients over the past three decades. Most patients are not diagnosed until the cancer is at an advanced stage, by which time their chances of still being alive after 5 years are appallingly low. Attempts to extend life in these patients have been, for the most part, unsuccessful. This owes partly to the lack of suitable biomarkers for stratifying patients at the molecular level, into responders and non-responders. This would lead to more drugs being shown to have a clinical benefit and being approved for use in subgroups of patients. There is also a desperate need for improved biomarkers for earlier detection of ovarian cancer; if the disease is detected sooner there is a significantly improved outlook. In this review, we outline the evidence that microRNAs are deregulated in ovarian cancer, what this can tell us about tumour progression and how it could be used to improve patient stratification in clinical trials. We also describe the potential for circulating microRNAs, both associated with proteins or carried in vesicles, to be used as diagnostics for earlier detection or as biomarkers for informing clinicians on the prognosis and best treatment of ovarian cancer. PMID- 27718165 TI - Polymorphisms in MIR122, MIR196A2, and MIR124A Genes are Associated with Clinical Phenotypes in Inflammatory Bowel Diseases. AB - BACKGROUND: Inflammatory bowel diseases (IBDs), including Crohn's disease (CD) and ulcerative colitis (UC), are multifactorial disorders that result from a dysregulated inflammatory response to environmental factors in genetically predisposed individuals. Recently, microRNAs (miRNAs) have been shown to be involved in the development of IBDs. AIMS: We investigated common variants in five miRNA genes in a cohort of Italian IBD patients, to evaluate their possible role in the disease's susceptibility and phenotype manifestations. METHODS: The analysis included 267 CD patients, 207 UC patients, and 298 matched healthy controls. Polymorphisms in the MIR122, MIR499, MIR146A, MIR196A2, and MIR124A genes were evaluated by allelic discrimination assay. RESULTS: We did not find associations between mir polymorphisms and IBD susceptibility. In both diseases, rs17669 and rs11614913 (MIR122 and MIR196A2) seem to contribute to clinical phenotypes: ileal location in CD (odds ratio [OR] = 1.82, p = 0.03; OR = 0.51, p = 0.01), and left-sided extent in UC (OR = 0.43, p = 0.05; OR = 0.28, p = 0.002). In CD, the MIR124A polymorphism (rs531564) contributed to colon location (p = 0.03, OR = 2.74). Finally, the variant allele of rs11614913 was associated with early age at onset in both diseases (p = 0.05 and p = 0.02). CONCLUSIONS: We showed for the first time that polymorphisms in MIR122, MIR196A2, and MIR124A could play a role in clinical phenotype modulation in IBD.

AB - Skin can respond to various types of internal and/or external mechanostimuli, such as excessive tension caused by body growth or decompression due to weight loss, which significantly affect skin morphology. Mechanosensors, including p130Cas, are reported to play a role in deformation and subsequent recovery of various tissues including skeletal muscles and blood vessels. However, the role of mechanotransduction via p130Cas in the regulation of skin size remains unclear. In this report, p130Cas activation was manipulated using a fibroblast embedded collagen gel model or mouse skin contraction model. Inhibition or activation of Src family kinase-mediated phosphorylation of p130Cas significantly depressed and accelerated collagen gel contraction, respectively. The results also demonstrated age-dependent depression of cutaneous p130Cas activation in vivo. Inhibition of p130Cas signaling in our mouse model significantly suppressed recovery from cutaneous deformation. Taken together, our study highlighted the important role of p130Cas in cutaneous mechanotransduction for skin homeostasis.

AB - In this study, paraffin was selected as a base material and mixed with different amounts of CaSO4.2H2O and H3BO3 compounds in order to mimic breast tissue. Slab phantoms were produced with suitable mixture ratios of the additives in the melted paraffin. Subsequently, these were characterized in terms of first half value layer (HVL) in the mammographic X-ray range using a pulse-height spectroscopic analysis with a CdTe detector. Irradiations were performed in the energy range of 23-35 kVp under broad beam conditions from Mo/Mo and Mo/Rh target/filter combinations. X-ray spectra were acquired with a CdTe detector without and with phantom material interposition in increments of 1 cm thickness and then evaluated to obtain the transmission data. The net integral areas of the spectra for the slabs were used to plot the transmission curves and these curves were fitted to the Archer model function. The results obtained for the slabs were compared with those of standard mammographic phantoms such as CIRS BR series phantoms and polymethylmethacrylate plates (PMMA). From the evaluated transmission curves, the mass attenuation coefficients and HVLs of some mixtures are close to those of the commercially available standard mammography phantoms. Results indicated that when a suitable proportion of H3BO3 and CaSO4.2H2O is added to the paraffin, the resulting material may be a good candidate for a breast tissue equivalent phantom.

AB - Since the early 2000s, continuous glucose monitoring (CGM) technology has advanced to become a standard of care in the treatment of type 1 diabetes.

Additionally, it will review recent clinical trial data demonstrating the benefits that CGM offers to all people with type 1 diabetes and the clinicians who care for them. PMID- 27718173 TI - Neuroinflammation, immune system and Alzheimer disease: searching for the missing link. AB - Due to an increasingly aging population, Alzheimer disease (AD) represents a crucial issue for the healthcare system because of its widespread prevalence and the burden of its care needs. Several hypotheses on AD pathogenesis have been proposed and current therapeutical strategies have shown limited effectiveness. In the last decade, more evidence has supported a role for neuroinflammation and immune system dysregulation in AD. It remains unclear whether astrocytes, microglia and immune cells influence disease onset, progression or both. Amyloid beta peptides that aggregate extracellularly in the typical neuritic plaques generate a constant inflammatory environment. This causes a prolonged activation of microglial and astroglial cells that potentiate neuronal damage and provoke the alteration of the blood brain barrier (BBB), damaging the permeability of blood vessels. Recent data support the role of the BBB as a link between neuroinflammation, the immune system and AD. Hence, a thorough investigation of the neuroinflammatory and immune system pathways that impact neurodegeneration and novel exciting findings such as microglia-derived microvesicles, inflammasomes and signalosomes will ultimately enhance our understanding of the pathological process. Eventually, we should proceed with caution in defining a causal or consequential role of neuroinflammation in AD, but rather focus on identifying its exact pathological contribution.

AB - Postprandial symptoms of neuroglycopenia after bariatric surgery may result as a consequence of endogenous hyperinsulinemic hypoglycemia (nesidioblastosis) not dumping syndrome. Pancreatectomy is an acceptable treatment for this condition. We present the video of a case of near-total distal robotic pancreactectomy for the treatment of nesidioblastosis after Roux-en-Y gastric bypass. Robotic pancreatectomy is an alternative to the treatment of nesidioblastosis after Roux en-Y gastric bypass. PMID- 27718176 TI - LSG vs OAGB-1 Year Follow-up Data-a Randomized Control Trial. AB - OBJECTIVES: Laparoscopic sleeve gastrectomy (LSG) is one of the most popular bariatric procedure. One anastomosis gastric bypass (OAGB) is rapidly emerging as a safe and effective metabolic procedure. This study aims at comparing the 1-year follow-up results of OAGB and LSG in terms of excess weight loss, complications, resolution of comorbidities, and quality of life. METHODS: A prospective randomized study of results between 100 LSG and 101 OAGB patients was done from 2012 to 2015. The results were compared regarding operative outcomes, percentage of excess weight loss, complications, resolution of comorbidities, and quality of life (BAROS score). RESULTS: The mean BMI for the OAGB and LSG group was 44.31 and 43.75 kg/m2, respectively. Percentage of excess weight loss (%EWL) for OAGB vs LSG was 66.87 +/- 10.87 vs 63.97 +/- 13.24 at 1 year (p > 0.05), respectively. Diabetes remission was 83.63 % in OAGB patients and 76.58 % in LSG patients. Remission of hypertension is 64.15 % in OAGB patients and 66.07 % in LSG patients. Bariatric Analysis Reporting and Outcome System (BAROS) was 3.71 in LSG and 3.96 in OAGB. CONCLUSIONS: In our study, there was no significant difference between LSG and OAGB in outcome at 1 year follow-up in % excess weight loss, remission of HTN, and quality of life. OAGB has marginally better outcome in T2 DM remission. However, a longer follow-up is required to establish a correct comparative result. PMID- 27718177 TI - A Novel Endoscopic Bariatric Procedure: Results of an Experimental Study. AB - BACKGROUND: Surgical treatment of obesity is characterized by both early and late complications, and thus, there is a need to develop safe and non-invasive techniques. Ghrelin is an orexigenic hormone produced by the fundus of the stomach, which may represent a novel target for obesity management. Unfortunately, numerous attempts to alter ghrelin levels have failed to present significant clinical results. We describe a novel procedure that involves modifying arterial blood flow to the gastric fundus for limiting plasma ghrelin levels. METHODS: A gastroscope was advanced into the gastric fundus of 13 healthy Yorkshire swine, and the fundus was clipped under direct visualization to restrict left gastric artery blood flow. Body weights and ghrelin levels were recorded before and once a week for 4 weeks after the procedure. RESULTS: Compared to controls, gastroscopic clipping of the fundus decreased plasma ghrelin levels and prevented further weight gain in the 4 weeks of follow-up. Immunohistochemistry and histomorphometry revealed reduced numbers of ghrelin positive cells in the fundus of experimental animals. We also observed thrombosis in submucosal arteries and submucosal fibrosis. Histological studies demonstrated minimal gastric mucosal injury. CONCLUSION: Gastroscopic clipping of the fundus in an experimental porcine model resulted in sustained weight loss and a reduction in plasma ghrelin levels at 1 month post-procedure, with no adverse events. Further experimental studies in human patients are needed to examine the clinical utility of this procedure and to optimize a technique, which can facilitate adequate weight loss while minimizing the risk of mucosal injury. PMID- 27718178 TI - QT Interval Shortening After Bariatric Surgery Depends on the Applied Heart Rate Correction Equation. AB - BACKGROUND: A shortening of electrocardiographic QT interval has been observed in obese subjects after weight loss, but previous results may have been biased by inappropriate heart rate (HR) correction. METHODS: Electrocardiography (ECG) recordings of 49 (35 females) severely obese patients before and 12 months after Roux-en-Y gastric bypass (RYGB) surgery were analysed. QT interval (QTc) was calculated by using four different equations, i.e. Bazett, Fridericia, Framingham and Hodges. RESULTS: Irrespectively of the used correction formula, QTc interval length was reduced after the surgery (QTcBazett -31 +/- 18 ms; QTcFridericia -12 +/- 15 ms; QTcFramingham -14 +/- 15 ms; QTcHodges -9 +/- 15 ms; all Ps < 0.001), but QTcBazett reduction was significantly greater than the reduction in QTc calculated upon the other three equations (all Ps < 0.001). Moreover, changes in QTcBazett (P < 0.001) but not in QTcFridericia, QTcFramingham and QTcHodges (all Ps > 0.05) were significantly correlated with concurrent changes in HR. Multivariate regression analyses revealed a significant independent association of serum insulin levels with QTcFridericia, QTcFramingham and QTcHodges values (all Ps < 0.05) preoperatively, whilst changes in QTc interval length after the surgery were not consistently associated to concurrent changes in metabolic traits. CONCLUSIONS: Our data show that the extent of weight loss-associated QTc interval shortening largely depends on the applied HR correction equation and appears to be overestimated when the most popular Bazett's equation is used. PMID- 27718179 TI - Assessment of Folate Status in Obese Patients: Should We Measure Folate in Serum or in Red Blood Cells? AB - BACKGROUND: Recent studies revealed that obesity is associated with decreased serum but at the same time increased red blood cell (RBC) folate concentrations compared with lean subjects, thus casting doubt upon the agreement between serum and RBC folate measurements for assessing folate status. This work aimed to determine whether these two metrics lead to the same classification of folate status in obese patients. METHODS: RBC and serum folate concentrations were measured with a chemiluminescent immunoassay in 263 adults with body mass index >=30 kg/m2 and without previous bariatric surgery. Among them, 68.1 % were eligible for bariatric surgery. Each serum and RBC folate result was classified as deficient or not according to thresholds recommended by the kit manufacturer (model A) or by the World Health Organization (model B). The agreement between serum and RBC folate results was evaluated using the proportion of overall agreement and the prevalence-adjusted bias-adjusted kappa (PABAK) statistics. RESULTS: The overall percentage agreements between serum and RBC measurements were 91.6 % (95 % CI 87.6-94.7 %) and 92.4 % (95 % CI 88.5-95.3 %) with PABAK coefficients of 0.87 (95 % CI 0.82-0.93) and 0.88 (95 % CI 0.83-0.94) in the models A and B, respectively, corresponding to almost perfect agreement. The same was true in the subgroup of patients eligible for bariatric surgery. Gender, age, and BMI did not influence the quality of agreement between the two parameters. CONCLUSIONS: The present study showed that folate measurements in serum and in RBC display similar performances to assess folate status in obese patients. PMID- 27718180 TI - Linking bronchopulmonary dysplasia to adult chronic lung diseases: role of WNT signaling. AB - Bronchopulmonary dysplasia (BPD) is one of the most common chronic lung diseases in infants caused by pre- and/or postnatal lung injury. BPD is characterized by arrested alveolarization and vascularization due to extracellular matrix remodeling, inflammation, and impaired growth factor signaling. WNT signaling is a critical pathway for normal lung development, and its altered signaling has been shown to be involved in the onset and progression of incurable chronic lung diseases in adulthood, such as chronic obstructive pulmonary disease (COPD) or idiopathic pulmonary fibrosis (IPF). In this review, we summarize the impact of WNT signaling on different stages of lung development and its potential contribution to developmental lung diseases, especially BPD, and chronic lung diseases in adulthood. PMID- 27718182 TI - Overview of Vaccine Adjuvants: Introduction, History, and Current Status. AB - Adjuvants are included in sub-unit or recombinant vaccines to enhance the potency of poorly immunogenic antigens. Adjuvant discovery is as complex as it is a multidiscplinary intersection of formulation science, immunology, toxicology, and biology. Adjuvants such as alum, which have been in use for the past 90 years, have illustrated that adjuvant research is a methodical process. As science advances, new analytical tools are developed which allows us to delve deeper into the various mechanisms that generates a potent immune response. Additionally, these new techniques help the field learn about our existing vaccines and what makes them safe, and effective, allowing us to leverage that in the next generation of vaccines. Our goal in this chapter is to define the concept, need, and mechanism of adjuvants in the vaccine field while describing its history, present use, and future prospects. More details on individual adjuvants and their formulation, development, mechanism, and use will be covered in depth in the next chapters. PMID- 27718183 TI - Development of the CpG Adjuvant 1018: A Case Study. AB - The development of aluminum salts (alum) as vaccine adjuvants was an empirical process with little understanding of the mechanism of action and, with decades of use, it has become clear that there is a need for alternatives where alum-based adjuvants are suboptimal. Oligonucleotides containing unmethylated CpG sequences represent one alternative as they are potent stimulators of the vertebrate innate immune system through activation of Toll-like receptor-9. This chapter outlines the methods used by Dynavax Technologies to progress a CpG-containing oligonucleotide sequence termed 1018 through preclinical and clinical testing as an adjuvant for immunization against hepatitis B virus (HBV). 1018 is a short (22 mer) oligonucleotide sequence containing CpG motifs active in both rodents and primates. Preclinical testing of hepatitis B surface antigen (HBsAg) + 1018 in comparison to HBsAg + alum demonstrated induction of substantially higher antibody titers and a favorable safety profile for 1018. Most importantly, clinical studies with HBsAg vaccination consistently demonstrate more rapid induction of protective antibody titers with 1018 compared to alum in all populations studied, including groups that are harder to immunize such as the elderly and immunocompromised individuals. These studies represent the basis for use of the CpG-motif-containing oligonucleotide 1018 as an improved adjuvant for HBsAg immunogenicity. HBsAg + 1018 (HEPLISAV-BTM) is currently in late-stage clinical testing for prophylactic immunization against HBV. PMID- 27718184 TI - Syntheses of Human TLR8-Specific Small-Molecule Agonists. AB - Human toll-like receptor (hTLR)-8 is expressed in myeloid dendritic cells, monocytes, and monocyte-derived dendritic cells. Engagement by TLR8 agonists evokes a distinct cytokine profile which favors the development of type 1 helper T cells. Focused exploration of structure-activity relationships in the imidazoquinolines has led to the identification of several novel human TLR8 specific agonists. The synthetic procedures for best-in-class analogues encompassing four chemotypes are described. PMID- 27718186 TI - QS-21 Adjuvant: Laboratory-Scale Purification Method and Formulation Into Liposomes. AB - QS-21, a saponin extracted from the tree Quillaja saponaria Molina, is a vaccine adjuvant which has been shown to elicit robust antibody and cell-mediated immune responses in a variety of preclinical and clinical studies [1]. Its purification from the natural source is a lengthy and difficult process. The commercially available saponin mixture Quil-A(r) is a fraction of the bark extract containing a variety of saponins, including QS-21. In order to facilitate access to QS-21 at laboratory-scale amounts, we propose here a method of purification of QS-21 starting from Quil-A(r). In addition, we describe a protocol to appropriately formulate QS-21 into cholesterol-containing, neutral liposomes which are known to decrease QS-21's hemolytic activity while retaining the adjuvant effect. Methods for the physicochemical characterization of purified QS-21 and of the QS 21/liposome formulations are also described. PMID- 27718181 TI - Uterine Adenosarcoma: a Review. AB - Adenosarcomas are rare malignancies of the female genital tract, accounting for approximately 5 % of uterine sarcomas. Occasionally, adenosarcoma occurs in the ovaries or in extra-uterine tissue, which may be related to endometriosis. These tumors are characterized by benign epithelial elements and a malignant mesenchymal component. Pathologic diagnosis is dependent on the identification of the characteristic morphologic features. The most common immunohistochemical markers for adenosarcoma are CD10 and WT1, but these are not specific. The most frequent presenting symptom is abnormal uterine bleeding. The majority of patients present with stage I disease, with a 5-year overall survival of 60 to 80 %. Survival is influenced by the presence of myometrial invasion, sarcomatous overgrowth, lymphovascular invasion, necrosis, and the presence of heterologous elements including rhabdomyoblastic differentiation. Patients with sarcomatous overgrowth have significantly increased risk of recurrence 23 versus 77 % and decreased 5-year overall survival 50 to 60 %. Standard of care treatment is total hysterectomy with bilateral salpingo-oophorectomy without lymphadenectomy, as the incidence of lymph node metastasis is rare. Retrospective data does not support the use of adjuvant pelvic radiotherapy in uterine adenosarcomas as no survival benefit is seen. Insufficient data exists to recommend routinely neoadjuvant or adjuvant chemotherapy for uterine adenosarcomas. Limited evidence exists for the role of hormonal therapy in uterine adenosarcomas. The PIK3/AKT/PTEN pathway is mutated in ~70 % of adenosarcomas, and this may represent a possible therapeutic target. This article reviews the current state of knowledge concerning uterine adenosarcoma and discusses the management of this rare tumor. PMID- 27718187 TI - Purification of an Immunoadjuvant Saponin Fraction from Quillaja brasiliensis Leaves by Reversed-Phase Silica Gel Chromatography. AB - Saponins include a large variety of molecules that find several applications in pharmacology. The use of Quillaja saponaria saponins as immunological adjuvants in vaccines is of interest due to their capacity to stimulate both humoral and cellular responses. The congener species Q. brasiliensis has saponins with chemical similarities and adjuvant activity comparable to that of Q. saponaria fraction Quil-A(r), with additional advantages of showing lower toxicity and reduced hemolytic activity. Here we describe in detail the methods for preparing the aqueous extract from Q. brasiliensis leaves, as well as the purification of the bioactive saponin fraction QB-90 using silica reversed-phase chromatography. PMID- 27718185 TI - Semisynthesis of Analogues of the Saponin Immunoadjuvant QS-21. AB - Saponins are triterpene glycoside natural products that exhibit many different biological properties, including activation and modulation of the immune system, and have therefore attracted significant interest as immunological adjuvants for use in vaccines. QS-21 is the most widely used and promising saponin adjuvant but suffers from several liabilities, such as scarcity, dose-limiting toxicity, and hydrolytic instability. Chemical synthesis has emerged as a powerful approach to obtain homogeneous, pure samples of QS-21 and to improve its properties and therapeutic profile by providing access to optimized, synthetic saponin variants. Herein, we describe a general method for the semisynthesis of these molecules from QS-21, with detailed synthetic protocols for two saponin variants developed in our recent work. PMID- 27718188 TI - Biosynthetic Approaches to Squalene Production: The Case of Yeast. AB - Squalene is a precursor in the eukaryotic sterol biosynthesis. It is a valuable compound with several human health-related applications. Since the traditional natural resources of squalene are limited, alternatives for the production of squalene on industrial scale have been intensively explored during past years. The yeast Saccharomyces cerevisiae represents an attractive option due to elaborated techniques of genetic and metabolic engineering that can be applied to improve squalene yields. We discuss in this chapter some theoretical aspects of genetic manipulations of the ergosterol biosynthesis pathway aimed at increased squalene production and describe analytical methods for squalene purification and determination of its content in yeast cells. PMID- 27718189 TI - In Silico Adjuvant Design and Validation. AB - Adjuvants are substances that boost the protective immune response to vaccine antigens. The majority of known adjuvants have been identified through the use of empirical approaches. Our aim was to identify novel adjuvants with well-defined cellular and molecular mechanisms by combining a knowledge of immunoregulatory mechanisms with an in silico approach. CD4+CD25+FoxP3+ regulatory T cells (Tregs) inhibit the protective immune responses to vaccines by suppressing the activation of antigen presenting cells such as dendritic cells (DCs). In this chapter, we describe the identification and functional validation of small molecule antagonists to CCR4, a chemokine receptor expressed on Tregs. The CCR4 binds the chemokines CCL22 and CCL17 that are produced in large amounts by activated innate cells including DCs. In silico identified small molecule CCR4 antagonists inhibited the migration of Tregs both in vitro and in vivo and when combined with vaccine antigens, significantly enhanced protective immune responses in experimental models. PMID- 27718190 TI - Manufacturing Methods for Liposome Adjuvants. AB - A wide range of studies have shown that liposomes can act as suitable adjuvants for a range of vaccine antigens. Properties such as their amphiphilic character and biphasic nature allow them to incorporate antigens within the lipid bilayer, on the surface, or encapsulated within the inner core. However, appropriate methods for the manufacture of liposomes are limited and this has resulted in issues with cost, supply, and wider scale application of these systems. Within this chapter we explore manufacturing processes that can be used for the production of liposomal adjuvants, and we outline new manufacturing methods can that offer fast, scalable, and cost-effective production of liposomal adjuvants. PMID- 27718191 TI - Synthesis of Lymph Node-Targeting Adjuvants. AB - Molecular adjuvants based off of pattern recognition receptor agonists are capable of potently stimulating innate immunity and inducing protective immune responses to subunit antigens. One significant disadvantage to these small molecule adjuvants is their pharmacokinetic profile of entering the blood stream rather than the lymphatics after parental injection. In order to target molecular adjuvants to lymph nodes, we have developed nanoparticle carriers whose size has been optimized to avoid the blood and efficiently drain to lymph nodes (Hanson et al. Vaccine 33:861-8,2015; Hanson et al. J Clin Invest 125:2532-2546, 2015). This chapter describes in detail the materials and procedures necessary to synthesize liposome nanoparticle carriers of either hydrophobic or hydrophilic adjuvants, including synthesis tips, alternative equipment options, and pitfalls to avoid. PMID- 27718192 TI - Preparing an Adjuvanted Thermoresponsive Gel Formulation for Sublingual Vaccination. AB - Thermoresponsive gels have unique physicochemical properties that may enable more effective mucosal delivery of active compounds. The thermoresponsive gel (TRG) formulation developed by our group for sublingual delivery maintains fluid-like liquid properties at 2 degrees C-8 degrees C and forms a gel at the physiological temperature (~37 degrees C) within a few seconds. Here, we describe the preparation of a thermoresponsive gel vaccine formulation. Our preclinical studies with various antigens suggest that the mucoadhesive, adjuvanted TRG formulation enabled increased contact of the vaccine antigen with the mucosa, resulting in increased mucosal response(s) with a potential for antigen dose reduction. PMID- 27718193 TI - Manufacture of Oil-in-Water Emulsion Adjuvants. AB - Emulsion adjuvants for human vaccines have evolved gradually over the last century. Current formulations are the result of many refinements to their composition and manufacturing, as well as optimization for safety and efficacy. Squalene has emerged as being particularly suitable for the manufacturing of safe oil-in-water (O/W) adjuvants for parenteral applications due to its biocompatibility and ability to be metabolized. Emulsion particle size has been identified as an important parameter affecting the pharmaceutical performance of O/W emulsion adjuvants. Submicronic emulsions with sizes in the 80-200 nm range are preferred for potency, manufacturing consistency, and stability reasons. Two manufacturing processes, high pressure homogenization (HPH or microfluidization) and a phase inversion temperature method (PIT), are described to yield such fine and long-term stable emulsion adjuvants. PMID- 27718194 TI - Methods to Prepare Aluminum Salt-Adjuvanted Vaccines. AB - Many human vaccines contain certain insoluble aluminum salts such as aluminum oxyhydroxide and aluminum hydroxyphosphate as vaccine adjuvants to boost the immunogenicity of the vaccines. Aluminum salts have been used as vaccine adjuvants for decades and have an established, favorable safety profile. However, preparing aluminum salts and aluminum salt-adjuvanted vaccines in a consistent manner remains challenging. This chapter discusses methods to prepare aluminum salts and aluminum salt-adjuvanted vaccines, factors to consider during preparation, and methods to characterize the vaccines after preparation. PMID- 27718195 TI - Production of Adjuvant-Loaded Biodegradable Particles for Use in Cancer Vaccines. AB - Immune adjuvants, such as ligands for pathogen-associated molecular patterns (PAMPs), have been showing promise in boosting immune responses to tumor associated antigens, and delivering these adjuvants as discrete packages is considered advantageous over delivery in soluble form. Here we describe in detail, methods for independently loading a range of adjuvants into polymer-based biodegradable particles. We also describe the means by which to characterize these particles with respect to adjuvant loading and release kinetics as well as in terms of particle size, shape, and zeta-potential. These adjuvant-loaded particles have the potential to be used in dendritic cell-based uptake experiments performed in vitro or to be used in preclinical cancer vaccine research applications where they can be co-delivered with antigen-loaded particles or some other vaccine component comprising antigenic material. PMID- 27718196 TI - Lyophilization of Adjuvanted Vaccines: Methods for Formulation of a Thermostable Freeze-Dried Product. AB - Lyophilization of vaccines is advantageous for the distribution and storage of thermally labile products, particularly in regions where cold chain management is difficult. To date, current lyophilized vaccines do not contain an adjuvant. Instead, adjuvanted vaccines may be presented as a two vial system, that require bedside-mixing prior to immunization. Here we present an example of a lyophilization cycle that we have used to successfully freeze-dry an adjuvanted protein formulation in a single vial. PMID- 27718197 TI - Stressed Stability Techniques for Adjuvant Formulations. AB - Stressed stability testing is crucial to the understanding of mechanisms of degradation and the effects of external stress factors on adjuvant stability. These studies vastly help the development of stability indicating tests and the selection of stabilizing conditions for long term storage. In this chapter, we provide detailed protocols for the execution of forced degradation experiments that evaluate the robustness of adjuvant formulations against thermal, mechanical, freeze-thawing, and photo stresses. PMID- 27718198 TI - Particle Sizing of Nanoparticle Adjuvant Formulations by Dynamic Light Scattering (DLS) and Nanoparticle Tracking Analysis (NTA). AB - Dynamic light scattering (DLS) and nanoparticle tracking analysis (NTA) are two orthogonal and complementary methods of measuring size of particles in a sample. These technologies use the theory of Brownian motion by analyzing the random changes of light intensity scattered by particles in solution. Both techniques can be used to characterize particle size distribution of proteins and formulations in the nanometer to low micron range.Each method has benefits over the other. DLS is a quick and simple measurement that is ideal for monodisperse particles and can also analyze a distribution of particles over a wide range of sizes. NTA provides a size distribution that is less susceptible to the influence of a few large particles, and has the added benefit of being able to measure particle concentration. Here we describe methods for measuring the particle size and concentration of an oil-in-water nanoemulsion. PMID- 27718199 TI - Quantification of Multiple Components of Complex Aluminum-Based Adjuvant Mixtures by Using Fourier Transform Infrared Spectroscopy and Partial Least Squares Modeling. AB - Fourier transform infrared (FTIR) spectroscopy is widely used in the pharmaceutical industry for process monitoring, compositional quantification, and characterization of critical quality attributes in complex mixtures. Advantages over other spectroscopic measurements include ease of sample preparation, quantification of multiple components from a single measurement, and the ability to quantify optically opaque samples. This method describes the use of a multivariate model for quantifying a TLR4 agonist (GLA) adsorbed onto aluminum oxyhydroxide (Alhydrogel(r)) using FTIR spectroscopy that may be adapted to quantify other complex aluminum based adjuvant mixtures. PMID- 27718200 TI - Determination of Protein Content in Alhydrogel(r)-Based Vaccines by O Phthalaldehyde Assay. AB - The quantification of antigens adsorbed to aluminum-based adjuvants (alum) typically involves a method that first extracts antigen from the alum followed by the quantification of the antigen available in the extract. Extraction procedures often result in less than 100 % desorption of the antigen from the alum adjuvant and may alter the conformation of the antigen, reducing the accuracy of the subsequent method used for quantification. There is no generic method available for directly assessing the protein content when formulated on alum. Here we offer a method that can directly quantify protein adsorbed to Alhydrogel(r) using a simple fluorescence assay that is highly accurate and reproducible for Alhydrogel(r) formulations containing 25-400 MUg/mL of antigen. PMID- 27718201 TI - Staining and Transfer Techniques for SDS-PAGE Gels to Minimize Oil-in-Water Emulsion Adjuvant Interference. AB - Adjuvants in modern vaccines boost and shape immune responses and allow for antigen dose-sparing. Analysis of protein antigens in the presence of adjuvants can prove challenging, especially if the adjuvant interferes with visualization of the protein band on an SDS-PAGE gel. In this chapter, a variety of different techniques are presented to mitigate the interference of a nanoemulsion adjuvant, GLA-SE, with different recombinant proteins of varying molecular weight by addressing sample preparation and staining methods. PMID- 27718202 TI - Interactions Between Antigens and Nanoemulsion Adjuvants: Separation and Characterization Techniques. AB - Determining the association of vaccine components in a formulation is of interest for designing and optimizing well characterized vaccines. Three methods are described to assess interactions between protein antigens and oil-in-water nanoemulsion adjuvants. The methods include (1) ultracentrifugation to measure free versus adjuvant-associated protein, (2) size exclusion chromatography (SEC) to qualitatively assess existing interactions, and (3) Native PAGE as a means to visualize the formulation run in its native state on a polyacrylamide gel. As with many techniques, the methods alone are not definitive, but data from multiple orthogonal assays can provide a more complete picture of protein adjuvant interactions. PMID- 27718203 TI - Screening Vaccine Formulations in Fresh Human Whole Blood. AB - Monitoring the immunological functionality of vaccine formulations is critical for vaccine development. While the traditional approach using established animal models has been relatively effective, the use of animals is costly and cumbersome, and animal models are not always reflective of a human response. The development of a human-based approach would be a major step forward in understanding how vaccine formulations might behave in humans. Here, we describe a platform methodology using fresh human whole blood (hWB) to monitor adjuvant modulated, antigen-specific responses to vaccine formulations, which is amenable to analysis by standard immunoassays as well as a variety of other analytical techniques. PMID- 27718204 TI - Analysis of the Innate Response to Adjuvants: Characterization of the Draining Lymph Node by Fluorescence-Activated Cell Sorting. AB - A clear index for a response to adjuvants is a change in the cellular composition of lymph nodes draining the site of adjuvant injection (Didierlaurent et al., J Immunol 183:6186-6197, 2009; Caproni et al., J Immunol 188:3088-98, 2012; Desbien et al., Eur J Immunol 1-11, 2014). During the steady state, lymph nodes (LNs) are composed of a fixed ratio of innate and adaptive cells awaiting activation signals from tissue draining lymph. Upon exposure to innate stimulants, lymph nodes undergo dramatic changes. The most apparent change to the lymph node is an increase in size. Antigen-independent activation of naive T cells and B cells, as a consequence of type I interferon signaling, results in upregulation of CD69 (Sun and Zhang, J. Exp. Med 188:2335-2342, 1998), causing increased retention of cells in the lymph node and transient lymphopenia in the blood (Shiow et al., Nature 440:540-544, 2006). In addition tissue-resident dendritic cells, macrophages, as well as circulating inflammatory monocytes will migrate into draining LNs and display maturation markers associated with activation. Such features can provide powerful discrimination of adjuvant potencies.

AB - Quantification of cytokine production by CD4 and CD8 T cells after in vitro recall stimulation with the immunizing antigen is a powerful approach to characterize the cellular immune responses to immunization. Here we describe three complementary methods for such quantification including flow cytometric analysis of cytokine production by intracellular staining, ELISpot determination of the numbers of cytokine-producing cells, and generation of secreted cytokines and chemokines in culture supernatants for analysis by ELISA and/or cytometric bead arrays. PMID- 27718207 TI - Molecular Methods and Bioinformatic Tools for Adjuvant Characterization by High Throughput Sequencing. AB - Adjuvants in vaccine formulations are designed to enhance immune responses against a target antigen or pathogen. The ability of these vaccines to induce activation and differentiation of mature naive B cells to produce pathogen specific antibodies (immunoglobulins; Ig) helps guarantee long-lived humoral immunity. This process involves clonal expansion of antigen-specific B cells, genomic rearrangement of Ig heavy (IgH) and light (IgL) loci, somatic hypermutation (SHM), and clonal selection for affinity-matured antibody, resulting in a vast but directed repertoire of B cells expressing highly specific antibody proteins. High-throughput sequencing of the IgH and IgL complementary determining regions (CDRs) derived from various B cell populations provides an unprecedented way to observe dynamic responses of the humoral immune repertoire in response to vaccination. However, applying high-throughput sequencing (HTS) methodologies to multi-armed in vivo experiments requires careful coordination of sample preparation with downstream bioinformatics, particularly with regard to issues of quantitation, sequence fidelity, bar-coding, and multiplexing strategies. Here, we overview strategies of high-throughput sequencing and analysis of the adaptive immune complex loci applied to multi-armed, multiplexed experiments. PMID- 27718206 TI - Eliciting Epitope-Specific CD8+ T Cell Response by Immunization with Microbial Protein Antigens Formulated with alpha-Galactosylceramide: Theory, Practice, and Protocols. AB - CD8+ cytotoxic T lymphocytes confer protection against infectious diseases caused by viruses, bacteria, and parasites. Hence, significant efforts have been invested into devising ways to generate CD8+ T cell-targeted vaccines. Generation of microbe-free protein subunit vaccines requires a thorough knowledge of protective target antigens. Such antigens are proteolytically processed peptides presented by MHC class I molecules. To induce a robust antigen-specific CD8+ T cell response through vaccination, it is essential to formulate the antigen with an effective adjuvant. Here, we describe a versatile method for generating high frequency antigen-specific CD8+ T cells through immunization of mice using the invariant natural killer T cell agonist alpha-galactosylceramide as the adjuvant. PMID- 27718208 TI - Caricature generalization benefits for faces learned with enhanced idiosyncratic shape or texture. AB - Recent findings show benefits for learning and subsequent recognition of faces caricatured in shape or texture, but there is little evidence on whether this caricature learning advantage generalizes to recognition of veridical counterparts at test. Moreover, it has been reported that there is a relatively higher contribution of texture information, at the expense of shape information, for familiar compared to unfamiliar face recognition. The aim of this study was to examine whether veridical faces are recognized better when they were learned as caricatures compared to when they were learned as veridicals-what we call a caricature generalization benefit. Photorealistic facial stimuli derived from a 3 D camera system were caricatured selectively in either shape or texture by 50 %. Faces were learned across different images either as veridicals, shape caricatures, or texture caricatures. At test, all learned and novel faces were presented as previously unseen frontal veridicals, and participants performed an old-new task. We assessed accuracies, reaction times, and face-sensitive event related potentials (ERPs). Faces learned as caricatures were recognized more accurately than faces learned as veridicals. At learning, N250 and LPC were largest for shape caricatures, suggesting encoding advantages of distinctive facial shape. At test, LPC was largest for faces that had been learned as texture caricatures, indicating the importance of texture for familiar face recognition. Overall, our findings demonstrate that caricature learning advantages can generalize to and, importantly, improve recognition of veridical versions of faces. PMID- 27718210 TI - Renin-angiotensin system in vertebrates: phylogenetic view of structure and function. AB - Renin substrate, biological renin activity, and/or renin-secreting cells in kidneys evolved at an early stage of vertebrate phylogeny. Angiotensin (Ang) I and II molecules have been identified biochemically in representative species of all vertebrate classes, although variation occurs in amino acids at positions 1, 5, and 9 of Ang I. Variations have also evolved in amino acid positions 3 and 4 in some cartilaginous fish. Angiotensin receptors, AT1 and AT2 homologues, have been identified molecularly or characterized pharmacologically in nonmammalian vertebrates. Also, various forms of angiotensins that bypass the traditional renin-angiotensin system (RAS) cascades or those from large peptide substrates, particularly in tissues, are present. Nonetheless, the phylogenetically important functions of RAS are to maintain blood pressure/blood volume homeostasis and ion fluid balance via the kidney and central mechanisms. Stimulation of cell growth and vascularization, possibly via paracrine action of angiotensins, and the molecular biology of RAS and its receptors have been intensive research foci. This review provides an overview of: (1) the phylogenetic appearance, structure, and biochemistry of the RAS cascade; (2) the properties of angiotensin receptors from comparative viewpoints; and (3) the functions and regulation of the RAS in nonmammalian vertebrates. Discussions focus on the most fundamental functions of the RAS that have been conserved throughout phylogenetic advancement, as well as on their physiological implications and significance. Examining the biological history of RAS will help us analyze the complex RAS systems of mammals. Furthermore, suitable models for answering specific questions are often found in more primitive animals. PMID- 27718209 TI - Lipopolysaccharide Binding Protein and Oxidative Stress in a Multiple Sclerosis Model. AB - Recent findings in experimental autoimmune encephalomyelitis (EAE) suggest that altering certain bacterial populations present in the gut may lead to a proinflammatory condition, that could result in the development of multiple sclerosis (MS). Also, Reactive Oxygen Species seem to be involved in the course of MS. In this study, it has been aimed to relate all these variables starting from an analysis of the lipopolysaccharide (LPS) and LPS-binding protein (LBP) with the determination of parameters related to oxidative stress in the blood, brain and spinal cord. For this purpose, samples obtained from EAE rats and relapsing-remitting (RRMS) MS patients were used. In addition, EAE rats were treated with Natalizumab, N-acetyl-cysteine and dimethyl fumarate. Natalizumab was also employed in RRMS. The results of this study revealed an improvement in the clinical symptoms of the EAE and MS with the treatments, as well as a reduction in the oxidative stress parameters and in LBP. Correlations between the clinical variables of the disease, i.e. oxidative damage and LBP, were established. Although the conclusions of this research are indeed relevant, further investigation would be necessary to establish the intrinsic mechanisms of the MS-oxidative stress-microbiota relationship. PMID- 27718212 TI - Table of Phenylalanine Content of Foods: Comparative Analysis of Data Compiled in Food Composition Tables. AB - BACKGROUND: Knowing the phenylalanine (Phe) content of foods is essential for managing the diet of patients with phenylketonuria. Data on the Phe content of foods are scarce and sometimes vary between different Food Composition Tables (FCT). Brazil created its own table of the Phe contents of fruits and vegetables based exclusively on the chemical analysis of protein content, considering that proteins contain 3-4% Phe (TCFA/ANVISA). This study compared the protein and Phe contents of vegetables and fruits provided by the TCFA/ANVISA with those listed in international food composition tables. METHODS: The Phe content of 71 fruits and vegetables listed in TCFA/ANVISA was classified into four subgroups, and the Wilcoxon nonparametric test compared the Phe and mean protein contents provided by the FCTs. All tests considered the bilateral hypothesis, and the level of significance was set at 5%. The Spearman's correlation coefficient measured the statistical dependence between Phe and protein contents. RESULTS: The mean Phe content was <50 mg Phe/100 g for 15 fruits; >50 mg/100 g for 11 type-A vegetables; <50 mg/100 g for 8 type-B vegetables; <=50 mg/100 g for 7 type-C vegetables. The percentage of Phe in protein varied from 3.13 +/- 1.03% to 3.74 +/- 2.55% in fruits; 3.33 +/- 1.41 to 4.82 +/- 1.17 in type-A vegetables; 3.46 +/ 1.25% to 4.83 +/- 2.46 in type-B vegetables; and 3.14% +/- 1.49 to 4.62% +/- 2.26 in type-C vegetables. CONCLUSIONS: The Phe and protein contents provided by most FCTs were positively correlated, suggesting that it is possible to estimate the Phe content of fruits by multiplying its protein content by 3%. For type-A, B, and -C vegetables, 4% may be used. PMID- 27718211 TI - Review of functional MRI in HIV: effects of aging and medication. AB - HIV-associated neurocognitive disorder (HAND) is a frequently occurring comorbidity of HIV infection. Evidence suggests this condition starts subclinical before a progression to a symptomatic stage. Blood oxygenated level dependent (BOLD) fMRI has shown to be a sensitive tool to detect abnormal brain function in an early stage and might therefore be useful to evaluate the effect of HIV infection on brain function. An extensive literature search was performed in June 2015. Eligibility criteria for included studies were as follows: (1) conducting with HIV-positive patients, (2) using BOLD fMRI, and (3) including a HIV-negative control group. A total of 19 studies were included in the review including 931 participants. Differences in activation between HIV-positive and -negative participants were found when testing multiple domains, i.e., attention, (working) memory, and especially executive functioning. Overall, HIV-positive patients showed hyperactivation in task-related brain regions despite equal performances as controls. Task performance was degraded only for the most complex tasks. A few studies investigated the effect of aging on fMRI, and most of them found no interaction with HIV infection. Only three studies evaluated the effect of combination antiretroviral therapy (cART) on functional data suggesting an increase in activation with the use of cART. fMRI is a sensitive instrument to detect subtle cognitive changes in HIV patients. Open questions remain regarding the effects of cART on fMRI and the effects of aging on fMRI. PMID- 27718213 TI - Whole resting cells vs. cell free extracts of Candida parapsilosis ATCC 7330 for the synthesis of gold nanoparticles. AB - The cell free extracts of Candida parapsilosis ATCC 7330 are more efficient than the whole resting cells of the yeast in the synthesis of directly usable gold nanoparticles as revealed by this systematic study. Cell free extracts yielded gold nanoparticles of hydrodynamic diameter (50-200 nm). In this study, the total protein concentration influences the nanofabrication and not only the reductase enzymes as originally thought. Powder X-ray diffraction studies confirm the crystalline nature of the gold nanoparticles. Fourier Transform Infra Red spectroscopy and thermal gravimetric analysis suggests that the biosynthesized gold nanoparticles are capped by peptides/proteins. Dispersion experiments indicate a stable dispersion of gold nanoparticles in pH 12 solutions which is also confirmed by electron microscopic analysis and validated using a surface plasmon resonance assay. The effectiveness of the dispersed nanoparticles for the reduction of 4-nitrophenol using sodium borohydride as a reductant further confirms the formation of functional gold nanoparticles. It is also reported that gold nanoparticles with mean particle diameter of 27 nm are biosynthesized inside the whole cell by transmission electron microscopy analysis. With optimized reaction conditions, maximum gold bioaccumulation with the 24 h culture age of the yeast with cellular uptake of ~1010 gold atoms at the single cell level is achieved but it is not easy to extract the gold nanoparticles from the whole resting cells. PMID- 27718214 TI - Effect of textile dyes on activity and differential regulation of laccase genes from Pleurotus ostreatus grown in submerged fermentation. AB - This research was conducted to extend the knowledge on the differential regulation of laccase genes in response to dyes. In order to accomplish this, we analyzed both, the expression of five laccase genes by real time RT-qPCR, and also the laccase activity and isoforms patterns during the time-course of a Pleurotus ostreatus submerged fermentation supplemented with either acetyl yellow G (AYG) or remazol brilliant blue R (RBBR) dyes. For the purpose of obtaining a stable reference gene for optimal normalization of RT-quantitative PCR gene expression assays, we tested four candidate reference genes. As a result of this analysis, gpd was selected as reference index for data normalization. The addition of dyes had an induction effect on the enzymatic activity and also modified the zymogram profile. Fermentation with RBBR showed the highest laccase activity and number of isoforms along the course of the fermentation. Laccase gene expression profiles displayed up/down regulation along the fermentation time in four laccase genes (pox4, pox3, poxa1b and pox2), while pox1 was not expressed in either of the fermentation conditions. AYG addition caused the highest induction and repression levels for genes pox3 and poxa1b respectively. The expression level for all genes in the presence of RBBR were lower than in AYG, being in both conditions this response growth time dependent. These results show the influence of the nature of dyes on the induction level of laccase activity and on the differential regulation of the laccase genes expression in P. ostreatus. PMID- 27718215 TI - Pyruvate production using engineered Escherichia coli. AB - Pyruvate plays an essential role in the central carbon metabolism of multiple organisms and is used as a raw material in the chemical, biochemical and pharmaceutical industries. To meet demand, large amounts of pyruvate are produced through fermentation processes. Here we describe a simple and efficient method for producing pyruvate in Escherichia coli. To stop carbon flux from pyruvate to fatty acids, the accBC genes, which encode the enzyme that catalyzes the first step of fatty acid biosynthesis and is essential for vegetative growth, were manipulated within the genome; its native promoter was replaced with the tetracycline (or doxycycline)-regulated promoter and the corresponding transcriptional regulator genes. The resulting strain grew normally in the presence of doxycycline, but showed poor growth upon withdrawal of doxycycline. Using this strain, we developed a high pyruvate producing strain (strain LAFCPCPt accBC-aceE), in which the tetracycline-regulated promoter was also introduced upstream of aceE, and the ackA-pta, adhE, cra, ldhA, pflB and poxB genes were deleted. After determining the optimal culture conditions for this strain, the final pyruvate concentration reached 26.1 g L-1 after 72 h with a theoretical yield of 55.6 %. These levels are high enough to indicate that the developed strain has the potential for application to industrial production of pyruvate. PMID- 27718216 TI - Predictors of Progression in IgA Nephropathy in Childhood. AB - The aim of this retrospective study was to assess the usefulness of potential predictors of poor prognosis in IgA nephropathy in children. The study population consisted of 55 children aged 11 +/- 4 years, diagnosed on the basis of the Oxford classification and MEST score of kidney biopsy findings. Proteinuria, glomerular filtration rate (GFR), and the IgA/C3 serum ratio were assessed in all patients twice: at onset and at follow-up. The patients were treated with steroids, immunosuppressive drugs, and/or angiotensin-converting enzyme inhibitors. Follow-up was at 3.9 +/- 2.9 (median 2.7) years. The patients were subdivided into two groups: with GFR <90 and >=90 mL/min at follow-up. ROC AUC curves and logistic regression were used to evaluate the power of prognostic factors. The two groups did not differ regarding the level of proteinuria, MEST score, and the IgA/C3 ratio at onset of disease. There was a significant association between GFR reductions at onset and follow-up (AUC = 0.660; p < 0.05). In patients with nephrotic range proteinuria at onset, proteinuria at follow-up was more frequent compared with other patients (AUC = 0.760; p < 0.05), MEST score >=3 tended to be associated with reduced GFR (AUC = 0.650; p = 0.07) but not with proteinuria (AUC = 0.608; p = 0.47), and the IgA/C3 ratio was higher (p < 0.05) at follow-up. No significant associations were found between the IgA/C3 ratio at onset and reduced GFR (AUC = 0.565; p = 0.46) or proteinuria at follow-up (AUC = 0.263; p = 0.20). We conclude that predictors of poor outcome in childhood IgAN include the following: GFR reduction, nephrotic range proteinuria at onset of disease, and high MEST score in Oxford classification of kidney biopsy. Despite a higher serum IgA/C3 ratio in children with impaired renal function in long-term follow-up, we failed to demonstrate a significant association between this ratio at onset of disease and reduced GFR or persistent proteinuria at follow-up. Thus, IgA/C3 ratio is not a good foreteller of progression of IgA nephropathy in childhood. PMID- 27718217 TI - Animal Models of Implant-Related Low-Grade Infections. A Twenty-Year Review. AB - The demand for joint replacement and surgical treatment is continuously increasing, thus representing a clinical burden and a cost for the healthcare system. Among several pathogens involved in implant-related infections, staphylococci account for the two-thirds of clinically isolated bacteria. Despite most of them are highly virulent microorganisms (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa), low virulent bacteria (Staphylococcus epidermidis, Propionibacterium acnes) are responsible for delayed, low-grade infections without specific clinical signs and hardly distinguishable from aseptic prosthetic failure. Therefore, there is a real need to study the pathogenesis of orthopedic infections through in vivo animal models. The present review of the literature provides a 20-year overview of animal models of acute, subclinical or chronic orthopedic infections according to the pathogen virulence and inocula. Through this analysis, a great variety of conditions in terms of bacterial strains and inocula emerged, thus encouraging the development of more reproducible in vivo studies to provide relevant information for a translational approach to humans. PMID- 27718218 TI - Medication Adherence Contributes to an Improved Quality of Life in Type 2 Diabetes Mellitus Patients: A Cross-Sectional Study. AB - INTRODUCTION: Diabetes mellitus is a chronic disease with a high prevalence world wide. This disease has also been reported to affect the quality of life (QOL) of the patient and their family due to its chronic nature and multi organ involvement. The aim of this study was to analyze the association between adherence to prescribed diabetes medication and diabetes-specific QOL in patients attending Secondary Health Care Facility in Bandung City, Indonesia. METHODS: A cross-sectional survey was conducted in the Secondary Health Care Facility in Bandung City, Indonesia. Data were collected between February and April 2014 using consecutive sampling. Adherence was assessed using the eight-item Morisky Medication Adherence Scale while diabetes-specific-QOL was assessed using the Diabetes 39 instrument. RESULTS: The results showed that among the patients, 49.4% exhibited low adherence, 29.7% exhibited medium adherence, and 20.9% exhibited high adherence to diabetes medication. Diabetes-specific QOL proved to be highly affected in the sexual functioning domain. Social-burden domain scores were better than overall QOL scores. There was a significant association between adherence and diabetes-specific QOL (p = 0.009) using The Kruskall-Wallis test of significance. The results of the post hoc Mann-Whitney tests (high vs medium adherence, p = 0.084; medium vs low adherence, p = 0.86; and high vs low adherence, p = 0.001) indicated that higher adherence to prescribed diabetes medication contributed to an improved QOL. Multiple regression analysis showed that the predictors of diabetes-specific QOL were adherence and patient income. CONCLUSIONS: Adherence to prescribed medication showed a positive effect on diabetes-specific QOL in patients. Patients with a high adherence to medication had an improved QOL. This result is important not only in developing intervention programs for patients but also in improving their QOL through sustainable health promotion. PMID- 27718219 TI - Molecular heterogeneity of aggrecan-based perineuronal nets around five subclasses of parvalbumin-expressing neurons in the mouse hippocampus. AB - Subsets of GABAergic neurons are surrounded by perineuronal nets (PNNs), which play a critical role in the regulation of neural plasticity and neuroprotection. Although the plant lectin Wisteria floribunda agglutinin (WFA) has been commonly used to label PNNs, WFA only detects N-acetyl-d-galactosamine on aggrecan, a member of the lectican family. In this study, we used WFA and the antibody against the core protein of aggrecan (ACAN) to investigate the molecular heterogeneity of aggrecan-based PNNs around five subclasses of parvalbumin expressing (PV+) gamma-aminobutyric acid (GABA)ergic neurons in the CA1 and CA3 regions of the mouse hippocampus. The vast majority of ACAN+ PNNs were colocalized with WFA in the stratum pyramidale, whereas a substantial population of ACAN+ PNNs lacked WFA labeling in the stratum oriens. We then defined the subclasses of PV+ neurons based on their cellular locations, molecular expression, and septal projection. Like the WFA+ PNNs, ACAN+ PNNs surrounded PV+ basket cells and bistratified cells but not axo-axonic cells. Unlike the WFA+ PNNs, ACAN+ PNNs frequently surrounded PV+ oriens-lacunosum moleculare cells and hippocampo-septal cells. Interestingly, the relative densities of GABAergic synapses were higher around PV+ neurons with ACAN+ PNNs than around those without ACAN+ PNNs. Degradation of WFA+ PNNs by chondroitinase ABC did not affect the GABAergic synaptic densities around PV+ neurons. Our findings suggest that the molecular composition of aggrecan-based PNNs around PV+ neurons may differ in a subclass-specific manner, and also might help determine the functional involvement of PNNs in the regulation of GABAergic synapses around PV+ neurons in the hippocampus.

PMID- 27718220 TI - Discrimination, Internalized Homonegativity, and Attitudes Toward Children of Same-Sex Parents: Can Secure Attachment Buffer Against Stigma Internalization? AB - With increasing numbers of same-sex couples raising children in the United States, discriminatory attitudes toward children of same-sex parents (ACSSP) are of increasing concern. As with other forms of stigma and discrimination, lesbian, gay, and bisexual (LGB) individuals are at risk for internalizing these societal attitudes, which can negatively affect parenting-related decisions and behaviors and the mental and physical health of their children. Secure attachment is characterized by positive views of the self as loveable and worthy of care that are understood to develop in early relationships with caregivers. Secure attachment has been associated with positive mental and physical health, including among LGB individuals and couples. This study aimed to test the potential buffering role of secure attachment against stigma internalization by examining associations among secure attachment, discrimination, internalized homonegativity (IH), and ACSSP in an online survey study of 209 U.S. adults in same-sex relationships. Bootstrap analyses supported our hypothesized moderated mediation model, with secure attachment being a buffer. Greater discrimination was indirectly associated with more negative ACSSP through greater IH for individuals with mean or lower levels, but not for individuals with higher than average levels of secure attachment, specifically because among those with higher levels of secure attachment, discrimination was not associated with IH. These findings build on and extend past research, with important implications for future research and clinical work with LGB individuals, same-sex couples, and their families, including potential implementation of interventions targeting attachment security. PMID- 27718221 TI - Auditory toxicity in late preterm and term neonates with severe jaundice. AB - AIM: Jaundice may cause auditory toxicity (auditory neuropathy and hearing loss). However, total serum bilirubin (TSB) does not discriminate neonates at risk for auditory toxicity. We compared TSB, bilirubin:albumin molar ratio (BAMR), and unbound bilirubin for their association with auditory toxicity in neonates with severe jaundice (TSB >=342MUmol/L, or that met exchange transfusion). METHOD: Neonates greater or equal to 34 weeks gestational age with severe jaundice during the first 2 postnatal weeks were eligible for prospective cohort study, unless they had craniofacial malformations, chromosomal disorders, toxoplasmosis, other infections, rubella, cytomegalovirus, herpes simplex infections, surgery, or family history of congenital deafness. RESULTS: Twenty-eight out of 100 neonates (mean gestational age 37.4wks; 59 males, 41 females) had auditory toxicity. Peak unbound bilirubin, but not peak TSB and BAMR, was associated with auditory toxicity (p<0.05) in neonates with severe (TSB <427.5MUmol/L) and extreme hyperbilirubinemia (TSB >=427.5MUmol/L). Area under the receiver operating characteristic curve for unbound bilirubin (0.78) was significantly greater (p=0.03) than TSB (0.54) among neonates with severe but not extreme hyperbilirubinemia. INTERPRETATION: Unbound bilirubin is more strongly associated with auditory toxicity than TSB and/or BAMR in greater or equal to 34 weeks gestational age neonates with severe jaundice. Unbound bilirubin is a better predictor than TSB in neonates with severe hyperbilirubinemia. PMID- 27718222 TI - DNA-doxorubicin interaction: New insights and peculiarities. AB - We have investigated the interaction of the DNA molecule with the anticancer drug doxorubicin (doxo) by using three different experimental techniques: single molecule stretching, single molecule imaging, and dynamic light scattering. Such techniques allowed us to get new insights on the mechanical behavior of the DNA doxo complexes as well as on the physical chemistry of the interaction. First, the contour length data obtained from single molecule stretching were used to extract the physicochemical parameters of the DNA-doxo interaction under different buffer conditions. This analysis has proven that the physical chemistry of such interaction can be modulated by changing the ionic strength of the surrounding buffer. In particular we have found that at low ionc strengths doxo interacts with DNA by simple intercalation (no aggregation) and/or by forming bound dimers. For high ionic strengths, otherwise, doxo-doxo self-association is enhanced, giving rise to the formation of bound doxo aggregates composed by 3 to 4 molecules along the double-helix. On the other hand, the results obtained for the persistence length of the DNA-doxo complexes is strongly force-dependent, presenting different behaviors when measured with stretching or non-stretching techniques. PMID- 27718223 TI - Observed Mother- and Father-Child Interaction Differences in Families with Medically Assisted Reproduction-Conceived Twins and Singletons. AB - Increased medically assisted reproduction (MAR) use to treat infertility has resulted in a growing twin birth rate. Little is known about parent-child relationships for twin relative to singleton children in middle childhood. This study fills this gap by examining parent-child relationships in 57 families with eighty 6- to 12-year-old MAR twin and singleton children using observational data (warm and supportive communication, control, and hostility). Nested ANCOVAs indicate that while mothers exhibit similar interactional behaviors toward twins and singletons, fathers have less optimum behaviors toward twins relative to singletons. Twins displayed less engaged behavior with mothers and fathers relative to singletons. Given the vitality of parent-child relationships for family and child adjustment, future studies should examine determinants and outcomes of twin-singleton relationship differences to bolster twins' and their families' functioning. PMID- 27718224 TI - Active tuberculosis detection by pouched rats in 2014: More than 2,000 new patients found in two countries. AB - Tuberculosis (TB) is a major problem in poor countries because sensitive diagnostic tools are unavailable. In 2014, our pouched rats evaluated sputum from 21,600 Tanzanians and 9,048 Mozambicans whose sputum had previously been evaluated by microscopy, the standard diagnostic for TB. Evaluation by the rats revealed 1,412 new patients with active TB in Tanzania and 645 new patients in Mozambique, increases of 39% and 53%, respectively, when compared to detections by microscopy alone. These results provide further support for the applied use of scent-detecting rats. PMID- 27718225 TI - The evolution of coexistence: Reciprocal adaptation promotes the assembly of a simple community. AB - Species coexistence may result by chance when co-occurring species do not strongly interact or it may be an evolutionary outcome of strongly interacting species adapting to each other. Although patterns like character displacement indicate that coexistence has often been an evolutionary outcome, it is unclear how often the evolution of coexistence represents adaptation in only one species or reciprocal adaptation among all interacting species. Here, we demonstrate a strong role for evolution in the coexistence of guppies and killifish in Trinidadian streams. We experimentally recreated the temporal stages in the invasion and establishment of guppies into communities that previously contained only killifish. We combined demographic responses of guppies and killifish with a size-based integral projection model to calculate the fitness of the phenotypes of each species in each of the stages of community assembly. We show that guppies from locally adapted populations that are sympatric with killifish have higher fitness when paired with killifish than guppies from allopatric populations. This elevated fitness involves effects traceable to both guppy and killifish evolution. We discuss the implications of our results to the study of species coexistence and how it may be mediated through eco-evolutionary feedbacks. PMID- 27718226 TI - Hepatocyte growth factor reduces CXCL10 expression in keratinocytes. AB - Keratinocytes secrete vascular endothelial growth factor (VEGF) and angioregulatory chemokines during cutaneous wound healing. Hepatocyte growth factor (HGF) promotes skin re-epithelialization by increasing VEGF expression in keratinocytes. Here, we investigated the regulatory roles of HGF in the expression of genes encoding angiogenic and angiostatic chemokines in keratinocytes and found that HGF specifically inhibits mRNA expression of the angiostatic chemokine CXCL10 in both mouse primary keratinocytes and in the human keratinocyte cell line HaCaT through the MEK/ERK cascade. Furthermore, HGF inhibited tumor necrosis factor-alpha-induced CXCL10 expression at both mRNA and protein levels in HaCaT cells. Thus, HGF may orchestrate angiogenesis in wounded skin by modulating both VEGF and CXCL10 expression in keratinocytes. PMID- 27718227 TI - A parallel stranded G-quadruplex composed of threose nucleic acid (TNA). AB - G-rich sequences can adopt four-stranded helical structures, called G quadruplexes, that self-assemble around monovalent cations like sodium (Na+ ) and potassium (K+ ). Whether similar structures can be formed from xeno-nucleic acid (XNA) polymers with a shorter backbone repeat unit is an unanswered question with significant implications on the fold space of functional XNA polymers. Here, we examine the potential for TNA (alpha-l-threofuranosyl nucleic acid) to adopt a four-stranded helical structure based on a planar G-quartet motif. Using native polyacrylamide gel electrophoresis (PAGE), circular dichroism (CD) and solution state nuclear magnetic resonance (NMR) spectroscopy, we show that despite a backbone repeat unit that is one atom shorter than the backbone repeat unit found in DNA and RNA, TNA can self-assemble into stable G-quadruplex structures that are similar in thermal stability to equivalent DNA structures. However, unlike DNA, TNA does not appear to discriminate between Na+ and K+ ions, as G-quadruplex structures form equally well in the presence of either ion. Together, these findings demonstrate that despite a shorter backbone repeat unit, TNA is capable of self-assembling into stable G-quadruplex structures. PMID- 27718228 TI - Prediction of renal function upon reperfusion by ex situ controlled oxygenated rewarming. AB - BACKGROUND: Post-transplant function of suboptimal kidney grafts can be improved but not accurately predicted by hypothermic machine perfusion. Therefore, a new concept of ex situ pre-implantation machine perfusion with controlled rewarming up to subnormothermic temperatures was developed and evaluated. MATERIALS AND METHODS: Porcine kidneys (n = 6/group) were retrieved before or 30 min after cardiac arrest of the donor and subjected to 18 h of static cold storage. In some cases, 90 min of machine-controlled oxygenated rewarming (COR) was added thereafter. Functional integrity was evaluated in all kidneys by subsequent normothermic reperfusion in vitro. After supplementation of the preservation solution (Custodiol-N solution + 5 g/L dextran 40) with 10 mg/dL creatinine, ex situ renal function was assessed by monitoring urine output, urinary creatinine and creatinine clearance at 20 degrees C. Functional integrity was evaluated in all kidneys by normothermic reperfusion. RESULTS: COR resulted in a more than twofold improvement of postreperfusion creatinine clearance, oxygen consumption and enzyme release upon reperfusion, when compared with static cold storage. Predictive discrimination between kidneys with good or impaired function upon reperfusion based on parameters during perfusion at 4 degrees C was only moderate. This improved significantly at 20 degrees C. Correlation with renal clearance upon reperfusion was weak for vascular resistance at 8 degrees (r2 = 0.2) and 20 degrees C (r2 = 0.41). Best correlation was found for clearance measurements at 20 degrees (r2 = 0.81). CONCLUSIONS: Reconditioning by controlled oxygenated rewarming up to 20 degrees C improves renal function after reperfusion and can be utilized to assess graft integrity of predamaged donor kidneys. PMID- 27718229 TI - Nicotinic acetylcholine receptors regulate vestibular afferent gain and activation timing. AB - Little is known about the function of the cholinergic efferents innervating peripheral vestibular hair cells. We measured vestibular sensory evoked potentials (VsEPs) in alpha9 knockout (KO) mice, alpha10 KO mice, alpha7 KO mice, alpha9/10 and alpha7/9 double KO mice, and wild-type (WT) controls. We also studied the morphology and ultrastructure of efferent terminals on vestibular hair cells in alpha9, alpha10, and alpha9/10 KOs. Both type I and type ll vestibular hair cells express the alpha9 and alpha10 subunits. The efferent boutons on vestibular cells in alpha9, alpha10, and alpha9/10 KOs appeared normal, but a quantitative analysis was not performed. Mean VsEP thresholds were significantly elevated in alpha9 and alpha9/10 KO animals. Some alpha9 and alpha9/10 KO animals, however, had normal or near-normal thresholds, whereas others were greatly affected. Despite individual variability in threshold responses, latencies were consistently shortened. The double alpha7/9 KO resulted in decreased variance by normalizing waveforms and latencies. The phenotypes of the alpha7 and alpha10 single KOs were identical. Both alpha7 and alpha10 KO mice evidenced normal thresholds, decreased activation latencies, and larger amplitudes compared with WT mice. The data suggest a complex interaction of nicotinic acetylcholine receptors (nAChRs) in regulating vestibular afferent gain and activation timing. Although the alpha9/10 heteromeric nAChR is an important component of vestibular efferent activity, other peripheral or central nAChRs involving the alpha7 subunit or alpha10 subunit and alpha9 homomeric receptors are also important.

AB - BACKGROUND: A simplified computer vision-based application using artificial neural network (ANN) depending on multilayer perceptron (MLP) for accurately classifying wheat grains into bread or durum is presented. The images of 100 bread and 100 durum wheat grains are taken via a high-resolution camera and subjected to pre-processing. The main visual features of four dimensions, three colors and five textures are acquired using image-processing techniques (IPTs). A total of 21 visual features are reproduced from the 12 main features to diversify the input population for training and testing the ANN model. The data sets of visual features are considered as input parameters of the ANN model. The ANN with four different input data subsets is modelled to classify the wheat grains into bread or durum. The ANN model is trained with 180 grains and its accuracy tested with 20 grains from a total of 200 wheat grains. RESULTS: Seven input parameters that are most effective on the classifying results are determined using the correlation-based CfsSubsetEval algorithm to simplify the ANN model. The results of the ANN model are compared in terms of accuracy rate. The best result is achieved with a mean absolute error (MAE) of 9.8 * 10-6 by the simplified ANN model. CONCLUSION: This shows that the proposed classifier based on computer vision can be successfully exploited to automatically classify a variety of grains. (c) 2016 Society of Chemical Industry.

AB - Drug transporter research conducted over the last several decades has led to a greatly advanced understanding of the mechanisms underlying the principles of drug absorption and disposition. Although many transporters remain poorly characterized, there is ample evidence that the drug transporter field will ultimately provide vital support to routine patient management, and will play a key role in the discovery, development, and evaluation of innovative, cutting edge therapies. PMID- 27718235 TI - The soluble cytoplasmic tail of CD45 (ct-CD45) in human plasma contributes to keep T cells in a quiescent state. AB - The cytoplasmic tail of CD45 (ct-CD45) is proteolytically cleaved and released upon activation of human phagocytes. It acts on T cells as an inhibitory, cytokine-like factor in vitro. Here, we show that ct-CD45 is abundant in human peripheral blood plasma from healthy adults compared with plasma derived from umbilical cord blood and plasma from patients with rheumatoid arthritis or systemic lupus erythematosus. Plasma depleted of ct-CD45 enhanced T-cell proliferation, while addition of exogenous ct-CD45 protein inhibited proliferation and reduced cytokine production of human T lymphocytes in response to TCR signaling. Inhibition of T-cell proliferation by ct-CD45 was overcome by costimulation via CD28. T-cell activation in the presence of ct-CD45 was associated with an upregulation of the quiescence factors Schlafen family member 12 (SLFN12) and Krueppel-like factor 2 (KLF2) as well as of the cyclin-dependent kinase (CDK) inhibitor p27kip1. In contrast, positive regulators of the cell cycle such as cyclin D2 and D3 as well as CDK2 and CDK4 were found to be downregulated in response to ct-CD45. In summary, we demonstrate that ct-CD45 is present in human plasma and sets the threshold of T-cell activation. PMID- 27718236 TI - Production of chlorothalonil hydrolytic dehalogenase from agro-industrial wastewater and its application in raw food cleaning. AB - BACKGROUND: To reduce the fermentation cost for industrialization of chlorothalonil hydrolytic dehalogenase (Chd), agro-industrial wastewaters including molasses, corn steep liquor (CSL) and fermentation wastewater were used to substitute for expensive carbon and nitrogen sources and fresh water for lab preparation. RESULTS: The results showed that molasses and CSL could replace 5% carbon source and 100% organic nitrogen source respectively to maintain the same fermentation level. Re-fermentation from raffinate of ultra-filtered fermentation wastewater could achieve 61.03% of initial Chd activity and reach 96.39% activity when cultured in a mixture of raffinate and 50% of original medium constituent. Typical raw foods were chosen to evaluate the chlorothalonil removal ability of Chd. After Chd treatment for 2 h at room temperature, 97.40 and 75.55% of 30 mg kg-1 chlorothalonil on cherry tomato and strawberry respectively and 60.29% of 50 mg kg-1 chlorothalonil on Chinese cabbage were removed. Furthermore, the residual activity of the enzyme remained at 78-82% after treatment, suggesting its potential for reuse. CONCLUSION: This study proved the cost-feasibility of large scale production of Chd from agro-industrial wastewater and demonstrated the potential of Chd in raw food cleaning.

AB - Assortative mating is critical for reproductive isolation during speciation; however, the mechanisms underlying mating preferences are often unknown. Assortative mating can be mediated through preferences for condition-dependent and adaptive ("magic") traits, but rigorously testing these hypotheses has been impeded by trait covariation in living organisms. We used computer-generated models to examine the role of body shape in producing association preferences between fish populations undergoing ecological speciation in different habitat types. We demonstrate that body shape can serve as an adaptive trait (variation in head size between populations) and a condition-dependent signal (variation in abdominal distention among individuals). Female preferences for stimuli varying in only one aspect of body shape uncovered evidence for body shape as a magic trait across population pairs, but no evidence for body shape serving as a condition-dependent signal. Evolution of preferences only in females from one habitat type as well as stronger preferences in sympatric nonsulfidic as opposed to allopatric nonsulfidic populations suggests that reinforcement may have played a role in producing the observed patterns. PMID- 27718238 TI - Electrophilic nitro-fatty acids suppress allergic contact dermatitis in mice. AB - BACKGROUND: Reactions between nitric oxide (NO), nitrite (NO2-), and unsaturated fatty acids give rise to electrophilic nitro-fatty acids (NO2 -FAs), such as nitro oleic acid (OA-NO2 ) and nitro linoleic acid (LNO2 ). Endogenous electrophilic fatty acids (EFAs) mediate anti-inflammatory responses by modulating metabolic and inflammatory signal transduction reactions. Hence, there is considerable interest in employing NO2 -FAs and other EFAs for the prevention and treatment of inflammatory disorders. Thus, we sought to determine whether OA NO2 , an exemplary nitro-fatty acid, has the capacity to inhibit cutaneous inflammation. METHODS: We evaluated the effect of OA-NO2 on allergic contact dermatitis (ACD) using an established model of contact hypersensitivity in C57Bl/6 mice utilizing 2,4-dinitrofluorobenzene as the hapten. RESULTS: We found that subcutaneous (SC) OA-NO2 injections administered 18 h prior to sensitization and elicitation suppresses ACD in both preventative and therapeutic models. In vivo SC OA-NO2 significantly inhibits pathways that lead to inflammatory cell infiltration and the production of inflammatory cytokines in the skin. Moreover, OA-NO2 is capable of enhancing regulatory T-cell activity. Thus, OA-NO2 treatment results in anti-inflammatory effects capable of inhibiting ACD by inducing immunosuppressive responses. CONCLUSION: Overall, these results support the development of OA-NO2 as a promising therapeutic for ACD and provides new insights into the role of electrophilic fatty acids in the control of cutaneous immune responses potentially relevant to a broad range of allergic and inflammatory skin diseases. PMID- 27718239 TI - Long-term manure amendments and chemical fertilizers enhanced soil organic carbon sequestration in a wheat (Triticum aestivum L.)-maize (Zea mays L.) rotation system. AB - BACKGROUND: The carbon sequestration potential is affected by cropping system and management practices, but soil organic carbon (SOC) sequestration potential under fertilizations remains unclear in north China. This study examined SOC change, total C input to soil and, via integration of these estimates over years, carbon sequestration efficiency (CSE, the ratio of SOC change over C input) under no fertilization (control), chemical nitrogen fertilizer alone (N) or combined with phosphorus and potassium fertilizers (NP, NK, PK and NPK), or chemical fertilizers combined with low or high (1.5*) manure input (NPKM and 1.5NPKM). RESULTS: Results showed that, as compared with the initial condition, SOC content increased by 0.03, 0.06, 0.05, 0.09, 0.16, 0.26, 0.47 and 0.68 Mg C ha-1 year-1 under control, N, NK, PK, NP, NPK, NPKM and 1.5NPKM treatments respectively. Correspondingly, the C inputs of wheat and maize were 1.24, 1.34, 1.55, 1.33, 2.72, 2.96, 2.97 and 3.15 Mg ha-1 year-1 respectively. The long-term fertilization-induced CSE showed that about 11% of the gross C input was transformed into SOC pool. CONCLUSION: Overall, this study demonstrated that decade-long manure input combined with chemical fertilizers can maintain high crop yield and lead to SOC sequestration in north China.

AB - The quaternary-amino-ethyl 1 (QAE1) isoforms of type III antifreeze proteins (AFPs) prevent the growth of ice crystals within organisms living in polar regions. We determined the antifreeze activity of wild-type and mutant constructs of the Japanese notched-fin eelpout (Zoarces elongates Kner) AFP8 (nfeAFP8) and characterized the structural and dynamics properties of their ice-binding surface using NMR. We found that the three constructs containing the V20G mutation were incapable of stopping the growth of ice crystals and exhibited structural changes, as well as increased conformational flexibility, in the first 310 helix (residues 18-22) of the sequence. Our results suggest that the inactive nfeAFP8s are incapable of anchoring water molecules due to the unusual and flexible backbone conformation of their primary prism plane-binding surface. PMID- 27718247 TI - TIM29 is a subunit of the human carrier translocase required for protein transport. AB - Hydrophobic inner mitochondrial membrane proteins with internal targeting signals, such as the metabolite carriers, use the carrier translocase (TIM22 complex) for transport into the inner membrane. Defects in this transport pathway have been associated with neurodegenerative disorders. While the TIM22 complex is well studied in baker's yeast, very little is known about the mammalian TIM22 complex. Using immunoprecipitation, we purified the human carrier translocase and identified a mitochondrial inner membrane protein TIM29 as a novel component, specific to metazoa. We show that TIM29 is a constituent of the 440 kDa TIM22 complex and interacts with oxidized TIM22. Our analyses demonstrate that TIM29 is required for the structural integrity of the TIM22 complex and for import of substrate proteins by the carrier translocase. PMID- 27718248 TI - A cluster-randomised, controlled trial of the impact of Cogmed Working Memory Training on both academic performance and regulation of social, emotional and behavioural challenges. AB - BACKGROUND: We explored whether school-based Cogmed Working Memory Training (CWMT) may optimise both academic and psychological outcomes at school. Training of executive control skills may form a novel approach to enhancing processes that predict academic achievement, such as task-related attention, and thereby academic performance, but also has the potential to improve the regulation of emotion, social problems and behavioural difficulties. METHODS: Primary school children (Mean age = 12 years, N = 148) were cluster-randomised to complete active CWMT, a nonadaptive/placebo version of CWMT, or no training. RESULTS: No evidence was found for training effects on task-related attention when performing academic tasks, or performance on reading comprehension and mathematics tasks, or teacher-reported social, emotional and behavioural difficulties. CONCLUSIONS: CWMT did not improve control of attention in the classroom, or regulation of social, emotional and behavioural difficulties. PMID- 27718249 TI - Glutathione upregulates cAMP signalling via G protein alpha 2 during the development of Dictyostelium discoideum. AB - Despite the importance of glutathione in Dictyostelium, the role of glutathione synthetase (gshB/GSS) has not been clearly investigated. In this study, we observed that increasing glutathione content by constitutive expression of gshB leads to mound-arrest and defects in 3',5'-cyclic adenosine monophosphate (cAMP) mediated aggregation and developmental gene expression. The overexpression of gpaB encoding G protein alpha 2 (Galpha2), an essential component of the cAMP signalling pathway, results in a phenotype similar to that caused by gshB overexpression, whereas gpaB knockdown in gshB-overexpressing cells partially rescues the above-mentioned phenotypic defects. Furthermore, Galpha2 is highly enriched at the plasma membrane of gshB-overexpressing cells compared to wild type cells. Therefore, our findings suggest that glutathione upregulates cAMP signalling via Galpha2 modulation during Dictyostelium development. PMID- 27718250 TI - European Survey on Adverse Systemic Reactions in Allergen Immunotherapy (EASSI): a real-life clinical assessment. AB - BACKGROUND: Outside clinical trials, data on systemic reactions (SRs) due to allergen immunotherapy (AIT) are scarce. METHODS: A prospective, longitudinal, web-based survey of 'real-life' respiratory allergen immunotherapy (AIT) clinical practice was conducted in France, Germany and Spain. SRs were recorded and coded according to the Medical Dictionary for Regulatory Activities (MedDRA) and risk factors associated with SRs were identified. RESULTS: A total of 4316 patients (corresponding to 4363 ongoing courses of AIT) were included. A total of 109 SRs were recorded, and 90 patients (2.1%) presented at least one SR. Most of the SRs occurred in subcutaneous allergen immunotherapy (SCIT) (89%, n = 97). The most frequently reported symptoms were urticaria, rhinitis, dyspnoea and cough. Respiratory symptoms appeared before skin symptoms. Most SRs occurred during the up-dosing phase (75.8%) and were mild in severity (71.6%). Intramuscular adrenaline was administered in 17 SRs, but only 65% of these were subsequently classified as anaphylaxis. Independent risk factors for SRs during SCIT were as follows: the use of natural extracts (odds ratio, OR) [95% confidence interval (CI)] = 2.74 [1.61-4.87], P = 0.001), the absence of symptomatic allergy medications (1.707 [1.008-2.892], P = 0.047), asthma diagnosis (1.74 [1.05-2.88], P = 0.03), sensitization to animal dander (1.93 [1.21-3.09], P = 0.006) or pollen (1.16 [1.03-1.30], P = 0.012) and cluster regimens (vs rush) (4.18 [1.21-14.37], P = 0.023). A previous episode of anaphylaxis increased the risk for anaphylaxis in SCIT (OR [95% CI] = 17.35 [1.91-157.28], P = 0.01). CONCLUSION: AIT for respiratory allergy is safe, with a low number of SRs observed in real-life clinical practice. A personalized analysis of risk factors could be used to minimize SRs. PMID- 27718251 TI - Speciation is associated with changing ornamentation rather than stronger sexual selection. AB - Although sexual ornamentation mediates reproductive isolation, comparative evidence does not support the hypothesis that stronger sexual selection promotes speciation. Prior analyses have neglected the possibility that decreases in ornamentation may also promote speciation, such that both increases and decreases in the strength of sexual selection and associated changes in ornamentation promote speciation. To test this hypothesis, we studied color ornamentation in one of the largest and fastest avian radiations, the estrildid finches. We show that more ornamented lineages do not speciate more, even though they tend to have faster rates of ornamental evolution, whereas changes in ornamentation (i.e., increases or decreases) are associated with speciation. This indicates that divergence in sexually selected ornamentation, rather than stronger sexual selection, promotes or is otherwise associated with speciation. We also show that gregariousness and investment in reproduction are related to the elaboration of some ornamental traits, suggesting ecological influences on speciation mediated by ornamentation. We conclude that past work focusing specifically on the strength of sexual selection may have greatly underestimated the importance of sexual ornamentation for speciation. PMID- 27718253 TI - Probing gas adsorption in MOFs using an efficient ab initio widom insertion Monte Carlo method. AB - We propose a novel biased Widom insertion method that can efficiently compute the Henry coefficient, KH , of gas molecules inside porous materials exhibiting strong adsorption sites by employing purely DFT calculations. This is achieved by partitioning the simulation volume into strongly and weakly adsorbing regions and selectively biasing the Widom insertion moves into the former region. We show that only few thousands of single point energy calculations are necessary to achieve accurate statistics compared to many hundreds of thousands or millions of such calculations in conventional random insertions. The methodology is used to compute the Henry coefficient for CO2 , N2 , CH4 , and C2 H2 in M-MOF-74(M = Zn and Mg), yielding good agreement with published experimental data. Our results demonstrate that the DFT binding energy and the heat of adsorption are not accurate enough indicators to rank the guest adsorption properties at the Henry regime.

AB - AIMS: The aim of this systematic review was to assess the efficacy of bisphosphonate therapy as an adjunct to scaling and root planing (SRP) in the management of periodontitis. METHODS: Databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and Cochrane Oral Health Group Trials Register databases) were searched up to and including July 2016. The primary outcome was probing depth (PD), and the secondary outcomes were changes in clinical attachment level (CAL) and bone defect (BD) fill. The mean differences (MD) of outcomes and 95% confidence intervals (CI) for each variable were calculated using random effect model. RESULTS: Eight clinical studies were included. Seven studies used alendronate as an adjunct to SRP; of these, four studies used topical application and three used oral alendronate. Considering the effects of adjunctive bisphosphonates as compared to SRP alone, a high degree of heterogeneity for PD (Q value = 39.6, P < 0.0001, I2 = 87.38%), CAL (Q value = 13.65, P = 0.008, I2 = 70.71%), and BD fill (Q value = 53.26, P < 0.0001, I2 = 92.49%) was noticed among both the groups. Meta-analysis showed a statistically significant PD reduction (MD = -1.18, 95% CI = -1.91 to -0.44, P = 0.002), CAL gain (MD = -0.69, 95% CI = -1.20 to -0.18, P = 0.008) and BD fill (MD = -2.36, 95% CI = -3.64 to -1.08, P < 0.001) for SRP + bisphosphonate treatment vs. SRP alone. CONCLUSIONS: Adjunctive bisphosphonate therapy appears to be effective in managing periodontitis, however, due to the potential risk of osteonecrosis of the jaws and short-term follow-up of the studies, their clinical application is debatable. PMID- 27718254 TI - Immune Response of Healthy Adults to the Ingested Probiotic Lactobacillus casei Shirota. AB - Daily ingestion of a probiotic drink containing Lactobacillus casei Shirota (LcS; 1.3 * 1010 live cells) by healthy adults for (1) 4-week LcS, (2) 6-week discontinuation of LcS and (3) a final 4 weeks of LcS was investigated. There was a significant increase in expression of the T cell activation marker CD3+ CD69+ in ex vivo unstimulated blood cells at weeks 10 and 14, and there was a significant increase in the NK cell marker CD3+ CD16/56+ in ex vivo unstimulated blood cells at weeks 4, 10 and 14. Expression of the NK cell activation marker CD16/56+ CD69+ in ex vivo unstimulated blood cells was 62% higher at week 10 and 74% higher at week 14. Intracellular staining of IL-4 in ex vivo unstimulated and PMA-/ionomycin-stimulated CD3+ beta7+ integrin blood cells was significantly lower at weeks 10 and 14. Intracellular staining of IL-12 in ex vivo unstimulated and LPS-stimulated CD14+ blood cells was significantly lower at weeks 4, 10 and 14. Intracellular staining of TNF-alpha in LPS-stimulated CD14+ blood cells was significantly lower at weeks 4, 10 and 14. Mucosal salivary IFN-gamma, IgA1 and IgA2 concentrations were significantly higher at week 14, but LcS did not affect systemic circulating influenza A-specific IgA or IgG and tetanus-specific IgG antibody levels. In addition to the decrease in CD3+ beta7+ integrin cell IL-4 and a reduced CD14+ cell pro-inflammatory cytokine profile, at week 14 increased expression of activation markers on circulating T cells and NK cells and higher mucosal salivary IgA1 and IgA2 concentration indicated a secondary boosting effect of LcS.

PMID- 27718257 TI - CE-MS for metabolomics: Developments and applications in the period 2014-2016. AB - CE-MS can be considered a useful analytical technique for the global profiling of (highly) polar and charged metabolites in various samples. Over the past few years, significant advancements have been made in CE-MS approaches for metabolomics studies. In this paper, which is a follow-up of a previous review paper covering the years 2012-2014 (Electrophoresis 2015, 36, 212-224), recent CE MS strategies developed for metabolomics covering the literature from July 2014 to June 2016 are outlined. Attention will be paid to new CE-MS approaches for the profiling of anionic metabolites and the potential of SPE coupled to CE-MS is also demonstrated. Representative examples illustrate the applicability of CE-MS in the fields of biomedical, clinical, microbial, plant, and food metabolomics. A complete overview of recent CE-MS-based metabolomics studies is given in a table, which provides information on sample type and pretreatment, capillary coatings, and MS detection mode. Finally, general conclusions and perspectives are given. PMID- 27718259 TI - Copper as an antibacterial material in different facilities. AB - : The present study was performed in real life settings in different facilities (hospital, kindergarten, retirement home, office building) with copper and copper alloy touch surface products (floor drain lids, toilet flush buttons, door handles, light switches, closet touch surfaces, corridor hand rails, front door handles and toilet support rails) in parallel to reference products. Pure copper surfaces supported lower total bacterial counts (16 +/- 45 vs 105 +/- 430 CFU cm 2 , n = 214, P < 0.001) and a lower occurrence of Staphylococcus aureus (2.6 vs 14%, n = 157, P < 0.01) and Gram-negatives (21 vs 34%, n = 214, P < 0.05) respectively than did reference surfaces, whereas the occurrence of enterococci (15%, n = 214, P > 0.05) was similar. The studied products could be assigned to three categories according to their bacterial loads as follows (P < 0.001): floor drain lids (300 +/- 730 CFU cm-2 , n = 32), small area touch surfaces (8.0 +/- 7.1 to 62 +/- 160 CFU cm-2 , n = 90) and large area touch surfaces (1.1 +/- 1.1 to 1.7 +/- 2.4 CFU cm-2 , n = 92). In conclusion, copper touch surface products can function as antibacterial materials to reduce the bacterial load, especially on frequently touched small surfaces. SIGNIFICANCE AND IMPACT OF THE STUDY: The efficiency of copper as an antimicrobial material has been noted in laboratory studies and in the hospital environment. The present study further shows that copper exerted an antibacterial effect in different facilities, i.e. in a hospital, a kindergarten, an office building and in a retirement home for the elderly. The study suggests that copper has potential use as an antibacterial material and therefore might serve as a means to lower the incidence of transmission of infectious agents from inanimate surfaces in different facilities, with everyday functions. PMID- 27718258 TI - Zinc oxide nanoparticles as a novel anticancer approach; in vitro and in vivo evidence. AB - Currently, the outcomes of conventional chemotherapeutic approaches are unsatisfactory. Clinical application of nanoparticles seems promising. We aim to evaluate the possible antitumor activity of zinc oxide nanoparticles (ZnONPs) as a chemotherapeutic approach in in vitro and in vivo experimental models. An in vitro study was performed on three different cell lines, namely human hepatocellular carcinoma (HEPG2), human prostate cancer (PC3), and none-small cell lung cancer (A549) cell lines. An in vivo study using diethylnitrosamine (DENA)-induced HCC in adult male Wistar rats was conducted to investigate the potential antitumor activity of ZnONPs in HCC and the possible underlying mechanisms. Hepatocellular carcinoma (HCC) was induced by oral administration of DENA given in drinking water (100 mg/L) for 8 weeks. Rats were allocated into four groups, namely a control group, an HCC control group receiving DENA alone, a ZnONPs (10 MUg/kg per week, intravenous (i.v.) for 1 month) control group, and a ZnONPs treatment group (receiving ZnONPs + DENA). ZnONPs significantly reduced the elevated serum levels of HCC-related tumor markers alphafetoprotein and alpha l-fucosidase and the apoptotic marker caspase-3 compared with the untreated HCC rats. In addition, treatment with ZnONPs significantly decreased the elevated levels of hepatocyte integrity and oxidative stress markers as compared with the untreated HCC control group. Furthermore, the histopathological study revealed anaplasia and fibrous degenerations which were significantly corrected by ZnONPs treatment. In conclusion, administration of ZnONPs exhibited a promising preclinical anticancer efficacy in HCC and could be considered as a novel strategy for the treatment HCC in clinical practices. PMID- 27718260 TI - Hybrid microfluidics combined with active and passive approaches for continuous cell separation. AB - Microfluidics, which is classified as either active or passive, is capable of separating cells of interest from a complex and heterogeneous sample. Active methods utilise external fields such as electric, magnetic, acoustic, and optical to drive cells for separation, while passive methods utilise channel structures, intrinsic hydrodynamic forces, and steric hindrances to manipulate cells. However, when processing complex biological samples such as whole blood with rare cells, separation with a single module microfluidic device is difficult. Hybrid microfluidics is an emerging technique, which utilises active and passive methods whilst fulfilling higher requirements for stable performance, versatility, and convenience, including (i) the ability to process multi-target cells, (ii) enhanced ability for multiplexed separation, (iii) higher sensitivity, and (iv) tunability for a wider operational range. This review introduces the fundamental physics and typical formats for subclasses of hybrid microfluidic devices based on their different physical fields; presents current examples of cell sorting to highlight the advantage and usefulness of hybrid microfluidics on biomedicine, and then discusses the challenges and perspective of future development and the promising direction of research in this field.

PMID- 27718262 TI - A 12-week, randomized, parallel-group, proof-of-concept study of tulobuterol patch and salmeterol inhaler as add-on therapy in adult-onset mild-to-moderate asthma. AB - Patch formulation of tulobuterol has been used in asthma treatment as a long acting beta2 -agonist (LABA) through sustained skin absorption. Its treatment efficacy, especially in small airways, remains poorly understood. The study aim was to investigate LABA add-on effects of tulobuterol patch (TP) and salmeterol inhaler (SA) on pulmonary function, asthma control and health status. Patients who had adult-onset under-control asthma, despite taking inhaled corticosteroids, were enrolled in a randomized, open-label, parallel-group, proof-of-concept study of 12-week add-on treatment with TP (n=16) or SA (n=17). Spirometry, impulse oscillometry (IOS), exhaled nitric oxide levels, and clinical questionnaires of asthma control, health status (St. George's Respiratory Questionnaire: SGRQ), and symptoms were evaluated every 4 weeks. Add-on treatment of SA significantly improved the spirometric indices of small airway obstruction (forced expiratory flow between 25% and 75% of FVC: FEF25-75 , and maximum expiratory flow at 25% of FVC: MEF25 ) and IOS indices of whole respiratory resistance (resistance at 5 Hz) as compared to TP. In intra-group comparisons, add-on treatment of TP improved the scores of the asthma control test and the total SGRQ, as well as the symptom and impact components of the SGRQ. SA add-on treatment improved FEV1 and IOS parameters of resistance at 20 Hz and reactance at 5 Hz. Neither of the treatments improved exhaled nitric oxide levels. In conclusion, add-on treatment of TP improved asthma control and health status, whereas SA improved pulmonary function measures associated with large and small airway involvement among patients with adult-onset mild-to-moderate asthma.

AB - A quantum mechanical/molecular mechanical (QM/MM) approach based on the density functional tight-binding (DFTB) theory is a useful tool for analyzing chemical reaction systems in detail. In this study, an efficient QM/MM method is developed by the combination of the DFTB/MM and particle mesh Ewald (PME) methods. Because the Fock matrix, which is required in the DFTB calculation, is analytically obtained by the PME method, the Coulomb energy is accurately and rapidly computed. For assessing the performance of this method, DFTB/MM calculations and molecular dynamics simulation are conducted for a system consisting of two amyloid-beta(1-16) peptides and a zinc ion in explicit water under periodic boundary conditions. As compared with that of the conventional Ewald summation method, the computational cost of the Coulomb energy by utilizing the present approach is drastically reduced, i.e., 166.5 times faster. Furthermore, the deviation of the electronic energy is less than 10-6 Eh. (c) 2016 Wiley Periodicals, Inc. PMID- 27718265 TI - Does fingerprinting truly represent the diversity of wine yeasts? A case study with interdelta genotyping of Saccharomyces cerevisiae strains. AB - : Simple and efficient genotyping methods are widely used to assess the diversity of a large number of microbial strains, e.g. wine yeasts isolated from a specific geographical area or a vintage. Such methods are often also the first to be applied, to decrease the number of strains deemed interesting for a more time consuming physiological characterization. Here, we aimed to use a physiologically characterized strain collection of 69 Saccharomyces cerevisiae strains from Hungarian wine regions to determine whether geographical origin or physiological similarity can be recovered by clustering the strains with one or two simultaneously used variations of interdelta genotyping. Our results indicate that although a detailed clustering with high resolution can be achieved with this method, the clustering of strains is largely contrasting when different primer sets are used and it does not recover geographical or physiological groups. SIGNIFICANCE AND IMPACT OF THE STUDY: Genotyping is routinely used for assessing the diversity of a large number of isolates/strains of a single species, e.g. a collection of wine yeasts. We tested the efficiency of interdelta genotyping on a collection of Saccharomyces wine yeasts from four wine regions of Hungary that was previously characterized physiologically. Interdelta fingerprinting recovered neither physiological nor geographical similarities, and in addition, the two different primer pairs widely used for this method showed conflicting and barely comparable results. Thus, this method does not necessarily represent the true diversity of a strain collection, but detailed clustering may be achieved by the combined use of primer sets.

AB - Influenza A virus (IAV) infection induces a strong immune response and regulates the expression of many host proteins. The collagen triple helix repeat containing 1 (CTHRC1) protein is a secreted protein that exhibits increased expression during the viral infection process. However, the regulatory function of IAV on CTHRC1 expression is obscure. In this study, we investigated the effect of IAV on CTHRC1 expression and its regulatory mechanism. A total of 106 serum specimens from healthy people and 80 serum specimens from patients infected with IAV were collected. The CTHRC1 levels in the sera from the IVA patients and healthy individuals were measured using an enzyme-linked immunosorbent assay (ELISA), and the differences were statistically analysed. A549 cells were infected with the IAV or delNS1 virus. Additionally, A549 cells were cotransfected with a eukaryotic non-structural NS1 protein gene expression plasmid and the CTHRC1 gene promoter reporter plasmid (pCTHRC1-Luc), and, the luciferase activities were assessed. The CTHRC1 mRNA and protein expression were detected using reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting, respectively. The serum CTHRC1 level was significantly higher in the IAV patients than in the healthy individuals. IAV upregulated the CTHRC1 mRNA and protein expression. The non-structural NS1 protein specifically activated CTHRC1 gene promoter activity and upregulated CTHRC1 mRNA and protein expression. The activation function had a dose-dependent effect, indicating that influenza virus upregulated CTHRC1 expression through its NS1 protein. PMID- 27718268 TI - Rank aggregation of local expert knowledge for conservation planning of the critically endangered saola. AB - There has been much recent interest in using local knowledge and expert opinion for conservation planning, particularly for hard-to-detect species. Although it is possible to ask for direct estimation of quantities such as population size, relative abundance is easier to estimate. However, an expert's knowledge is often geographically restricted relative to the area of interest. Combining (or aggregating) experts' assessments of relative abundance is difficult when each expert only knows a part of the area of interest. We used Google's PageRank algorithm to aggregate ranked abundance scores elicited from local experts through a rapid rural-appraisal method. We applied this technique to conservation planning for the saola (Pseudoryx nghetinhensis), a poorly known bovid. Near a priority landscape for the species, composed of 3 contiguous protected areas, we asked groups of local people to indicate relative abundances of saola and other species by placing beans on community maps. For each village, we used this information to rank areas within the knowledge area of that village for saola abundance. We used simulations to compare alternative methods to aggregate the rankings from the different villages. The best-performing method was then used to produce a single map of relative abundance across the entire landscape, an area larger than that known to any one village. This map has informed prioritization of surveys and conservation action in the continued absence of direct information about the saola.

AB - The frequency of sandfly-host contacts can be measured by host antibody levels against sandfly salivary proteins. Recombinant salivary proteins are suggested to represent a valid replacement for salivary gland homogenate (SGH); however, it is necessary to prove that such antigens are recognized by antibodies against various populations of the same species. Phlebotomus perniciosus (Diptera: Psychodidae) is the main vector of Leishmania infantum (Trypanosomatida: Trypanosomatidae) in southwest Europe and is widespread from Portugal to Italy. In this study, sera were sampled from naturally exposed dogs from distant regions, including Campania (southern Italy), Umbria (central Italy) and the metropolitan Lisbon region (Portugal), where P. perniciosus is the unique or principal vector species. Sera were screened for anti-P. perniciosus antibodies using SGH and 43-kDa yellow-related recombinant protein (rSP03B). A robust correlation between antibodies recognizing SGH and rSP03B was detected in all regions, suggesting substantial antigenic cross-reactivity among different P. perniciosus populations. No significant differences in this relationship were detected between regions. Moreover, rSP03B and the native yellow-related protein were shown to share similar antigenic epitopes, as canine immunoglobulin G (IgG) binding to the native protein was inhibited by pre-incubation with the recombinant form. These findings suggest that rSP03B should be regarded as a universal marker of sandfly exposure throughout the geographical distribution of P. perniciosus. PMID- 27718269 TI - Characterization of human cytochrome P450 mediated bioactivation of amodiaquine and its major metabolite N-desethylamodiaquine. AB - AIMS: Oxidative bioactivation of amodiaquine (AQ) by cytochrome P450s to a reactive quinoneimine is considered as an important mechanism underlying its idiosyncratic hepatotoxicity. However, because internal exposure to its major metabolite N-desethylamodiaquine (DEAQ) is up to 240-fold higher than AQ, bioactivation of DEAQ might significantly contribute to covalent binding. The aim of the present study was to compare the kinetics of bioactivation of AQ and DEAQ by human liver microsomes (HLM) and to characterize the CYPs involved in bioactivation of AQ and DEAQ. METHODS: Glutathione was used to trap reactive metabolites formed in incubations of AQ and DEAQ with HLM and recombinant human cytochrome P450s (hCYPs). Kinetics of bioactivation of AQ and DEAQ in HLM and involvement of hCYPs were characterized by measuring corresponding glutathione conjugates (AQ-SG and DEAQ-SG) using a high-performance liquid chromatography method. RESULTS: Bioactivation of AQ and DEAQ in HLM both exhibited Michaelis Menten kinetics. For AQ bioactivation, enzyme kinetical parameters were Km , 11.5 +/- 2.0 MUmol l-1 , Vmax , 59.2 +/- 3.2 pmol min-1 mg-1 and CLint , 5.15 MUl min 1 mg-1 . For DEAQ, parameters for bioactivation were Km , 6.1 +/- 1.3 MUmol l-1 , Vmax , 5.5 +/- 0.4 pmol min-1 mg-1 and CLint 0.90 MUl min-1 mg-1 . Recombinant hCYPs and inhibition studies with HLM showed involvement of CYP3A4, CYP2C8, CYP2C9 and CYP2D6 in bioactivation. CONCLUSIONS: The major metabolite DEAQ is likely to be quantitatively more important than AQ with respect to hepatic exposure to reactive metabolites in vivo. High expression of CYP3A4, CYP2C8, CYP2C9, and CYP2D6 may be risk factors for hepatotoxicity caused by AQ therapy. PMID- 27718270 TI - The impact of surface area, volume, curvature, and Lennard-Jones potential to solvation modeling. AB - This article explores the impact of surface area, volume, curvature, and Lennard Jones (LJ) potential on solvation free energy predictions. Rigidity surfaces are utilized to generate robust analytical expressions for maximum, minimum, mean, and Gaussian curvatures of solvent-solute interfaces, and define a generalized Poisson-Boltzmann (GPB) equation with a smooth dielectric profile. Extensive correlation analysis is performed to examine the linear dependence of surface area, surface enclosed volume, maximum curvature, minimum curvature, mean curvature, and Gaussian curvature for solvation modeling. It is found that surface area and surfaces enclosed volumes are highly correlated to each other's, and poorly correlated to various curvatures for six test sets of molecules. Different curvatures are weakly correlated to each other for six test sets of molecules, but are strongly correlated to each other within each test set of molecules. Based on correlation analysis, we construct twenty six nontrivial nonpolar solvation models. Our numerical results reveal that the LJ potential plays a vital role in nonpolar solvation modeling, especially for molecules involving strong van der Waals interactions. It is found that curvatures are at least as important as surface area or surface enclosed volume in nonpolar solvation modeling. In conjugation with the GPB model, various curvature-based nonpolar solvation models are shown to offer some of the best solvation free energy predictions for a wide range of test sets. For example, root mean square errors from a model constituting surface area, volume, mean curvature, and LJ potential are less than 0.42 kcal/mol for all test sets. (c) 2016 Wiley Periodicals, Inc.

AB - Most major neuropsychiatric outcomes of concern to families are not detectable by prenatal ultrasound. The introduction of genome-wide chromosomal microarray analysis to prenatal clinical diagnostic testing has increased the detection of pathogenic 22q11.2 deletions, which cause the most common genomic disorder. The recent addition of this and other microdeletions to non-invasive prenatal screening methods using cell-free fetal DNA has further propelled interest in outcomes. Conditions associated with 22q11.2 deletions include intellect ranging from intellectual disability to average, schizophrenia and other treatable psychiatric conditions, epilepsy, and early-onset Parkinson's disease. However, there is currently no way to predict how severe the lifetime expression will be. Available evidence suggests no major role in these neuropsychiatric outcomes for the congenital cardiac or most other structural anomalies that may be detectable on ultrasound. This article provides an outline of the lifetime neuropsychiatric phenotype of 22q11.2 deletion syndrome that will be useful to clinicians involved in prenatal diagnosis and related genetic counselling. The focus is on information that will be most relevant to two common situations: detection of a 22q11.2 deletion in a fetus or newborn, and new diagnosis of 22q11.2 deletion syndrome in a parent without a previous molecular diagnosis.

AB - BACKGROUND: Currently, the role of UPR signaling in prostate cancer (PCa) is unclear. To evaluate the relationship between UPR signaling pathway and the prognosis of PCa, we explored the expression of IRE1, PERK, and ATF6 in tissues. METHODS: A total of 160 PCa and 30 benign prostate hyperplasia (BPH) tissues were collected. The expression of UPR signaling factors was assessed by immunohistochemistry. The staining characteristics were identified and evaluated for associations with clinicopathologic parameters, PSA recurrence survival, and prostate cancer-specific morality. RESULTS: The expressions of ATF6alpha, PERK, and IRE1alpha were significantly associated with Gleason grade, PSA level, T stages and M stage, while this association was not significant in N stage. Additionally, UPR signaling factors expressed correlatively with each other. In further studies, high expression level of UPR signaling factors was usually detected in patients who suffered poor prognosis. Patients with positive UPR signaling factors meet shorter survival duration both on cancer-specific morality and PSA recurrence. Multivariate analysis showed that IRE1alpha (HR = 4.461 95%CI = 1.270-15.670 P = 0.020) could be a potential factor in predicting PSA recurrence independently. CONCLUSIONS: UPR signaling factors were co-activated and activation of UPR signaling was implicated to the malignant progression and worse prognosis of PCa. The mechanism and function of UPR signaling in PCa are still to be determined. Prostate 77:274-281, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27718274 TI - The prognostic value of stromal FK506-binding protein 1 and androgen receptor in prostate cancer outcome. AB - BACKGROUND: Improving our ability to predict cancer progression and response to conservative or radical intent therapy is critical if we are to prevent under or over treatment of individual patients. Whereas the majority of solid tumors now have a range of molecular and/or immunological markers to help define prognosis and treatment options, prostate cancer still relies mainly on histological grading and clinical parameters. We have recently reported that androgen receptor (AR) expression in stroma inversely associates with prostate cancer-specific survival, and that stromal AR reduces metastasis. For this paper, we tested the hypothesis that the AR-regulated gene FKBP51 could be used as a marker of AR activity to better predict outcome. METHODS: Using immunohistochemistry on a cohort of 64 patient-matched benign and malignant prostate tissues, we assessed patient outcome by FKBP51 and AR levels. Immunoblot and RT-qPCR were used to demonstrate androgen regulation of FKBP51 in primary and primary human prostatic fibroblasts and fibroblast cell-lines. RESULTS: As predicted by FKBP51 level, high AR activity in cancer stroma was associated with longer median survival (1,306 days) compared with high AR alone (699 days), whereas those with low AR and/or low FKBP51 did poorly (384 and 338 days, respectively). Survival could not be predicted on the basis cancer epithelial AR levels or activity, and was not associated with immunoreactivity in patient matched benign tissues. CONCLUSION: FKBP51 improves the ability of stromal AR to predict prostate cancer-specific mortality. By adding additional immunological assessment, similar to what is already in place in a number of other cancers, we could better serve patients with prostate cancer in prognosis and informed treatment choices.

AB - The non-targeted metabolomics analysis of biological samples is very important to understand biological functions and diseases. LC combined with electrospray ionization-based MS has been a powerful tool and widely used for metabolomic analyses. However, the ionization efficiency of electrospray ionization fluctuates for various unexpected reasons such as matrix effects and intraday variations of the instrument performances. To remove these fluctuations, normalization methods have been developed. Such techniques include increasing the sensitivity, separating co-eluting components and normalizing the ionization efficiencies. Normalization techniques allow simultaneously correcting of the ionization efficiencies of the detected metabolite peaks and achieving quantitative non-targeted metabolomics. In this review paper, we focused on these normalization methods for non-targeted metabolomics by LC-MS. PMID- 27718275 TI - Performance of ZDOCK and IRAD in CAPRI rounds 28-34. AB - We report the performance of our protein-protein docking pipeline, including the ZDOCK rigid-body docking algorithm, on 19 targets in CAPRI rounds 28-34. Following the docking step, we reranked the ZDOCK predictions using the IRAD scoring function, pruned redundant predictions, performed energy landscape analysis, and utilized our interface prediction approach RCF. In addition, we applied constraints to the search space based on biological information that we culled from the literature, which increased the chance of making a correct prediction. For all but two targets we were able to find and apply biological information and we found the information to be highly accurate, indicating that effective incorporation of biological information is an important component for protein-protein docking.

PMID- 27718277 TI - Protective effect of alpha-lipoic acid, aerobic or resistance exercise from colitis in second hand smoke exposed young rats. AB - The role of second hand smoke (SHS) exposure on ulcerative colitis is not known. Our aim was to examine the effects of alpha-lipoic acid (ALA), chronic aerobic (AE) or resistance exercise (RE) on SHS exposed rats with colitis. Sprague-Dawley male rats (150-200 g, n=54) were selected for colitis induction. Among the colitis groups, one group was exposed to SHS (6 d/wk, 4 cigarettes/d) and the other was not. The SHS group was divided into subgroups as follows: sedentary; AE (swimming; 3 d/wk); and RE (climbing with weight; 3 d/wk). After 5 weeks, colitis was induced by intrarectal acetic acid. All groups had subgroups that were given subcutaneously ALA (50 mg/kg per day) or vehicle for 3 days. Following decapitation, colon tissues were sampled to examine malondialdehyde (MDA) and glutathione (GSH) levels, myeloperoxidase (MPO) activity, luminol and lucigenin chemiluminenscence, macroscopic scoring and histologic examination. ANOVA and Student's t-test were used for statistical analysis. The increased macroscopic and microscopic scores, MPO, MDA, luminol and lucigenin measurements in colitis and SHS-colitis groups were decreased via ALA (P<.05-.001). AE declined macroscopic and microscopic scores, MDA, lucigenin compared to colitis and SHS colitis groups (P<.01-.001). RE reduced microscopic score, MPO, MDA, luminol, lucigenin (P<.05-.001) that were increased with colitis. Decreased GSH levels (P<.01) in the SHS-colitis group approached to control levels when given ALA. According to our results SHS and colitis induction increased inflammatory damage. SHS did not worsen it more than colitis. Our results suggest that ALA, AE or RE might be protective for SHS exposed ulcerative colitis conditions.

AB - AIM: We compared the effectiveness of a combined treatment involving cervical pessary plus vaginal progesterone to vaginal progesterone alone in decreasing the rate of preterm birth in women with short cervix in the second gestational trimester. METHODS: This prospective, open-label, randomized clinical trial was conducted on 144 pregnant women with singleton pregnancy who had a cervical length <= 25 mm, at 18-22 gestational weeks (GW). Seventy-three patients were assigned to receive 400 mg of daily vaginal progesterone (group A), and 73 to receive cervical pessary plus 400 mg of daily vaginal progesterone (group B), until the 37th GW. The patients were then followed until delivery. RESULTS: The rates of preterm birth were 16.4% in group A and 19.7% in group B, which were not statistically different (P = 0.6). There were no statistically significant differences in the rates of preterm birth at <37, <34, <32, and <=26 GW between participants randomized to each group (P = 0.55). The rates of low-birthweight delivery were 17.8% in group A, and 23.9% in group B, which were not statistically different (P = 0.36). The rates of premature rupture of membranes, chorioamnionitis, the requirement for neonatal intensive care unit admission, and fetal and neonatal deaths were similar between the two groups. CONCLUSION: In pregnancies with short cervix at mid-pregnancy, combination therapy of cervical pessary plus daily vaginal progesterone does not have any additional benefit over daily vaginal progesterone alone in reducing the rate of preterm birth and adverse pregnancy outcomes. PMID- 27718281 TI - Development of the anatomical quality assessment (AQUA) tool for the quality assessment of anatomical studies included in meta-analyses and systematic reviews. AB - Critical appraisal of anatomical studies is essential before the evidence from them undergoes meta-epidemiological synthesis. However, no instrument for appraising anatomical studies with inherent applicability to different study designs is available. We aim to develop a generic yet comprehensive tool for assessing the quality of anatomical studies using a formal consensus method. The study steering committee formulated an initial conceptual design and generated items for a preliminary tool on the basis of a literature review and expert opinion. A Delphi procedure was then adopted to assess the validity of the preliminary tool. Feedback from the Delphi panelists was used to improve it. The Delphi procedure involved 12 experts in anatomical research. It comprised two rounds, after which unanimous consensus was reached about the items to be included. The preliminary tool consisted of 20 items, which were phrased as signaling questions and organized into five domains: 1. Aim and subject characteristics, 2. Study design, 3. Characterization of methods, 4. Descriptive anatomy, and 5. Results reporting. Each domain was set to end with a risk of bias question. Following round 1, some of the items underwent major revision, although agreement was reached regarding inclusion of all the domains and signaling questions in the preliminary tool. The tool was revised only for minor language inaccuracies after round 2. The AQUA Tool was designed to assess the quality and reliability of anatomical studies. It is currently undergoing a validation process. Clin. Anat. 30:6-13, 2017. (c) 2016 Wiley Periodicals, Inc. PMID- 27718282 TI - Into the Andes: multiple independent colonizations drive montane diversity in the Neotropical clearwing butterflies Godyridina. AB - Understanding why species richness peaks along the Andes is a fundamental question in the study of Neotropical biodiversity. Several biogeographic and diversification scenarios have been proposed in the literature, but there is confusion about the processes underlying each scenario, and assessing their relative contribution is not straightforward. Here, we propose to refine these scenarios into a framework which evaluates four evolutionary mechanisms: higher speciation rate in the Andes, lower extinction rates in the Andes, older colonization times and higher colonization rates of the Andes from adjacent areas. We apply this framework to a species-rich subtribe of Neotropical butterflies whose diversity peaks in the Andes, the Godyridina (Nymphalidae: Ithomiini). We generated a time-calibrated phylogeny of the Godyridina and fitted time-dependent diversification models. Using trait-dependent diversification models and ancestral state reconstruction methods we then compared different biogeographic scenarios. We found strong evidence that the rates of colonization into the Andes were higher than the other way round. Those colonizations and the subsequent local diversification at equal rates in the Andes and in non-Andean regions mechanically increased the species richness of Andean regions compared to that of non-Andean regions ('species-attractor' hypothesis). We also found support for increasing speciation rates associated with Andean lineages. Our work highlights the importance of the Andean slopes in repeatedly attracting non Andean lineages, most likely as a result of the diversity of habitats and/or host plants. Applying this analytical framework to other clades will bring important insights into the evolutionary mechanisms underlying the most species-rich biodiversity hotspot on the planet.

AB - AIM: The aim of this study was to compare the outcome of two single-incision mini slings (the Contasure-Needleless [C-NDL] and the endopelvic free anchorage) with the standard midurethral transobturator tension-free vaginal tape (TVT-O) procedure. METHODS: A double blind randomized controlled study was conducted at Ain Shams University Maternity Hospital from August 2014 until July 2015. A total of 209 patients were randomized into three groups. The first group underwent the TVT-O procedure, the second group underwent the endopelvic free anchorage procedure and the third group underwent the C-NDL procedure. Patients were followed up for 12 months in terms of subjective cure, objective cure, and complications rate. RESULTS: After 12 months of follow-up, there were no differences among the three groups in terms of objective cure rate, subjective cure rate, patient satisfaction, or incidence of complications (de novo urge, hemorrhage, infection, and mesh erosion). The C-NDL was associated with a shorter operative time (P < 0.001) and less blood loss (P = 0.021) than the standard TVT O. CONCLUSION: The new single-incision mini-slings showed similar efficacy and patient acceptance to that of the standard TVT-O for up to 12 months postoperatively with no difference in the complications rate. The C-NDL is associated with shorter operative time and less blood loss. PMID- 27718285 TI - Concealed heterotopic pregnancy at 12 weeks, with no coexisting risk factors: Lessons to be learned. AB - A woman presented at the gynecological emergency clinic with severe lower abdominal pain. Even though she reported normal menses and had no risk factors for ectopic pregnancy, pregnancy test was positive and vaginal sonogram indicated heterotopic pregnancy at 12 weeks of gestation, with rupture of the ectopic pregnancy. Laboratory results indicated significant blood loss, and emergency laparotomy with salpingo-ophorectomy was performed. The intrauterine pregnancy continued uneventfully. Interestingly, the previous month the patient had also undergone investigation for vague abdominal pain and anemia. This case, apart from being very interesting because of the rarity of naturally occurring heterotopic pregnancy, shows how a number of factors in patient management and investigation, when combined with rare and uncommon conditions, can lead to incorrect diagnosis with the associated implications for patient safety. This case therefore demonstrates the need for improved patient care and outcome. PMID- 27718286 TI - Abdominal ectopic pregnancy with undetectable serum beta-human chorionic gonadotropin 9 days following blastocyst transfer. AB - With the availability of the highly sensitive beta-human chorionic gonadotropin (beta-hCG) assays, all pregnancies, including ectopic pregnancies (EP), are expected to have detectable serum beta-hCG at 4 weeks' gestation or 9 days following blastocyst transfer. To our knowledge, this is the first report of a woman who underwent in vitro fertilization, had undetectable serum beta-hCG 9 days after blastocyst transfer, and was then diagnosed with a ruptured abdominal EP and intra-abdominal bleeding 19 days later. This case highlights that the rise in serum beta-hCG might be delayed in abdominal EP compared to intrauterine pregnancy. This delay should raise the suspicion for EP, thus meriting close monitoring. Moreover, in the absence of menstruation, an undetectable serum beta hCG 9 days post-blastocyst transfer should prompt beta-hCG measurement in 2-3 days to avoid the misdiagnosis of an EP. PMID- 27718287 TI - Obstetrical management of patients with extra-anatomic vascular bypass grafts due to Takayasu arteritis. AB - Little is known about the obstetrical management of patients with Takayasu arteritis (TA) who have undergone extra-anatomic vascular bypass (EAVB). We describe two cases of EAVB. Case 1 underwent EAVB due to renovascular hypertension associated with stenosis of the abdominal aorta, and Case 2 due to amaurosis fugax episodes associated with stenosis of the brachiocephalic and left common carotid arteries. Pregnancy outcomes were favorable for both cases, though the original symptoms recurred during the third trimester in each case, possibly due to increased blood flow to the pregnant uterus. Neither bypass occlusion nor anastomotic aneurysm formation was observed. Pregnancy outcomes of patients with EAVB due to TA are favorable, although pregnancies of patients with TA who have cardiovascular complications are associated with an increased risk of maternal and fetal morbidity. The obstetrical management of these patients, however, should include monitoring for complications related to the EAVB.

AB - The gold carbene generated from vinylidenecyclopropanes (VDCPs) can smoothly perform a C(sp3 )-H bond insertion reaction, stereoselectively affording the intramolecular C(sp3 )-H bond functionalized product, benzoxepine, with syn configuration in moderate to good yields under mild conditions.

PMID- 27718288 TI - Usefulness of a management protocol for patients with cervical multicystic lesions: A retrospective analysis of 94 cases and the significance of GNAS mutation. AB - AIM: The proper preoperative diagnosis and management of cervical proliferative disorders presenting with multiple cysts, including minimal deviation adenocarcinoma (MDA), lobular endocervical glandular hyperplasia (LEGH), and nabothian cyst (NC), have not been fully established. We previously proposed a management protocol comprising a diagnostic approach using cytology, magnetic resonance imaging, and gastric-type mucin and subsequent treatment. We herein evaluate the usefulness of this protocol and implications of GNAS mutations in LEGH. METHODS: The clinical courses of 94 patients with cervical multicystic lesions who visited our hospital between June 1995 and September 2014 were retrospectively analyzed. GNAS mutations were investigated in 10 LEGH, five LEGH with atypia, and two MDA cases. RESULTS: Of the 94 patients, the conditions of 10, 59, and 25 were clinically diagnosed as suspicious of MDA or carcinoma (S/O MDA-Ca), suspicious of LEGH (S/O LEGH), and NC, respectively. Ten patients each with S/O MDA-Ca and S/O LEGH underwent hysterectomy, and the correct ratio for diagnosis was 90% (18/20). Of the 42 S/O LEGH cases followed-up for more than 12 months, three showed an increase in tumor size. After hysterectomy, two were LEGH with atypia while one was NC. The GNAS mutation was detected in two cases of LEGH with atypia, one of which showed an increase in tumor size during follow-up. CONCLUSION: The management protocol we propose herein will be useful. An increase in tumor size is important to detect potentially malignant LEGH. GNAS mutations may be involved in the tumorigenesis of potentially malignant LEGH.

We used a rat experimental periodontitis (PD) model induced by ligature placement with a Porphyromonas gingivalis LPS injection (PD rat) and analyzed the therapeutic effects of C16, a PKR inhibitor, on bone loss in PD rats. RESULTS: Protein kinase is strongly upregulated and phosphorylated by LPS in the osteoclasts. The inhibition of PKR suppressed LPS-stimulated osteoclast formation and activation. PKR inhibition also suppressed the LPS mediated activation of NF-kappaB and MAPK, which are critical pathways for osteoclastogenesis. High expressions of PKR were detected in osteoclasts of PD rats, and the treatment with C16 effectively prevented alveolar bone destruction in PD rats. CONCLUSIONS: PKR plays a pivotal role in LPS-induced bone loss in PD and, thus, has potential as a therapeutic target for PD.

AB - BACKGROUND AND PURPOSE: Twenty-four-hour ambulatory blood pressure and heart rate monitoring (24-h ABPM) can provide vital information on circadian blood pressure (BP) profiles, which are commonly abnormal in Parkinson's disease with and without autonomic failure (PD + AF and PD) and multiple system atrophy (MSA). Twenty-four-hour ABPM has not been directly compared between these disorders regarding cardiovascular autonomic function. Our aim was to determine the usefulness of 24-h ABPM with diary compared to head-up tilting (HUT) in diagnosing orthostatic hypotension (OH) in these patients. METHODS: Seventy-four patients (23 MSA, 18 PD + AF, 33 PD) underwent cardiovascular autonomic screening followed by 24-h ABPM with diary. Standing tests were included during 24-h ABPM. The sensitivity and specificity in detecting OH from the 24-h ABPM standing test were compared with HUT. RESULTS: There was no difference in OH during HUT between MSA and PD + AF (P > 0.05). There was a higher proportion of abnormal BP circadian rhythms in MSA and PD + AF compared to PD (P < 0.05) but not between MSA and PD + AF (P > 0.05). Patients were divided into groups with OH (OH+) and without OH (OH-) on HUT. Using the standing test during 24-h ABPM, a systolic BP fall of >20 mmHg showed a sensitivity and specificity of 82% and 100% (area under the curve 0.91, 95% confidence interval 0.84-0.98) in differentiating OH+ from OH . CONCLUSIONS: Parkinson's disease with autonomic failure and MSA patients had similar circadian BP patterns suggesting that autonomic dysfunction influences abnormal BP circadian patterns similarly in these disorders. The higher sensitivity and specificity in detecting OH using a systolic BP fall of >20 mmHg compared to a diastolic BP fall of >10 mmHg during the standing test supports its usefulness to assess autonomic function in MSA and PD.

AB - We present a rare case of a complication after pessary insertion during pregnancy due to short cervix. A woman in the 35th week of gestation was admitted to the Department of Perinatology due to preterm labor. The patient's history revealed cervical pessary insertion during the 29th week of pregnancy due to a cervix of 18 mm in length. Because of threatened preterm labor, the pessary was removed. After pessary removal, a rupture of the cervix was diagnosed. Because of active labor and cervical rupture, a cesarean section was performed and a healthy newborn was delivered. After cesarean section the cervical rupture was sutured. Five days after the operation, the patient underwent surgery again due to a necrotically changed part of the cervix. This part of the cervix was removed. We present this case to emphasize that cervical pessaries can cause serious complications during pregnancy. Clinicians should take this into consideration before qualifying patients for pessary insertion. PMID- 27718294 TI - Expression of anti-Mullerian hormone in two rat models of polycystic ovary syndrome. AB - AIM: Anti-Mullerian hormone (AMH) levels are two to three times higher in patients with polycystic ovary syndrome (PCOS), but the mechanism of increased AMH levels in PCOS remains unclear. The purpose of our experiment was to investigate a change in AMH levels in two kinds of commonly used rat models and to determine an ideal model for future research of AMH in the pathogenesis of PCOS. METHODS: Thirty female Sprague Dawley rats were treated using two modeling methods: implantation of a levonorgestrel silastic implant or injection with sodium prasterone sulfate plus human chorionic gonadotropin (hCG). Rats in the control group were implanted with a blank silastic stick. Serum steroid concentrations, ovarian morphology and ovarian expression of AMH and AMH-receptor II (RII) proteins were determined and their correlations were studied. RESULTS: The results from the levonorgestrel and hCG group were closer to those displayed by human PCOS patients than the sodium prasterone sulfate and hCG group. Ovarian local expression of AMH and AMH-RII was increased in these both models compared with the control group; however, an elevation of serum AMH concentration was not observed (12.53 +/- 0.99 ng/ml and 13.22 +/- 1.09 ng/ml vs 16.30 +/- 0.98 ng/ml). CONCLUSION: The levonorgestrel and hCG model is more suitable for the study of PCOS in puberty.

AB - Mosquitoes are insects of interest because several species vector disease-causing pathogens to humans and other vertebrates. We previously reported that mosquitoes from long-term laboratory cultures require living bacteria in their gut to develop, but development does not depend on particular species of bacteria. Here, we focused on three distinct but interrelated areas of study to better understand the role of bacteria in mosquito development by studying field and laboratory populations of Aedes aegypti, Aedes albopictus and Culex quinquefasciatus from the southeastern United States. Sequence analysis of bacterial 16S rRNA gene amplicons showed that bacterial community composition differed substantially in larvae from different collection sites, whereas larvae from the same site shared similarities. Although previously unknown to be infected by Wolbachia, results also indicated that Ae. aegypti from one field site hosted a dual infection. Regardless of collection site or factors like Wolbachia infection, however, each mosquito species required living bacteria in their digestive tract to develop. Results also identified several concerns in using antibiotics to eliminate the bacterial community in larvae in order to study its developmental consequences. Altogether, our results indicate that several mosquito species require living bacteria for development. We also hypothesize these species do not rely on particular bacteria because larvae do not reliably encounter the same bacteria in the aquatic habitats they develop in. PMID- 27718296 TI - Which type of placenta previa requires blood transfusion more frequently? A new concept of indiscernible edge total previa. AB - AIM: During cesarean section (CS) for placenta previa (PP), the size/area/portion of the lower uterine segment occupied by the placenta may affect the bleeding amount and the subsequent need for a blood transfusion (BT). We propose a new concept, indiscernible edge total PP (IEPP), when vaginal ultrasound does not discern the lower placental edge because the placenta covers the visible lower segment. We characterized IEPP, focusing on its allogeneic BT requirement. METHODS: We classified PP (n = 307) into four types: marginal, partial, discernible edge total PP (DEPP) and IEPP: internal ostium (os)-placental edge distance measurable or unmeasurable on vaginal ultrasound in DEPP or IEPP, respectively. We determined the clinical characteristics according to the four types; the relationship between the intraoperative blood loss and os-edge distance in DEPP; and risk factors for allogeneic BT. RESULTS: The following were significantly higher/larger in cases of IEPP: previous CS; anterior placentation; lacunae; elective cesarean hysterectomy; intraoperative blood loss; autologous BT; allogeneic BT; intensive care unit admission; and an abnormally invasive placenta (AIP). In DEPP, the os-edge distance was weakly correlated with the bleeding amount (r = 0.214). Multivariate logistic regression analysis showed that previous CS, lacunae, AIP and IEPP were independent risk factors for allogeneic BT (odds ratios 3.8, 3.1, 13.8 and 4.6, respectively). After excluding patients undergoing hemostatic procedures during CS, IEPP remained the only independent risk factor for allogeneic BT (odds ratio 5.2). CONCLUSIONS: The new concept of IEPP may be useful for predicting BT in CS for patients with PP. PMID- 27718297 TI - TRPA1 receptor is upregulated in human oral lichen planus. AB - OBJECTIVE: Oral lichen planus (OLP) is a chronic inflammatory disease of unknown etiology with antigen-specific and non-specific mechanisms. Transient receptor potential ankyrin 1 (TRPA1) is a non-selective cation channel activated by noxious stimuli such as oxidative stress products evoking pain and release of proinflammatory mediators from sensory nerve endings culminating in neurogenic inflammation. Extraneuronal TRPA1s, for example, on immune cells possess yet unknown functions. SUBJECTS AND METHODS: We studied the buccal mRNA expression (qPCR) and protein localization (immunohistochemistry) of TRPA1 receptors and key OLP mediator transcripts in oral mucosa samples of healthy volunteers (n = 9), OLP patients (n = 43), and OLP-like hyperkeratotic patients (n = 12). RESULTS: We measured 27.7- and 25.5-fold TRPA1 mRNA increase in OLP and OLP-like hyperkeratotic patients compared to healthy controls. TRPA1 transcripts elevated 2.4-fold in hypertensive OLP but not in hyperkeratotic patients compared to counterparts, reduced by 1.6-fold by angiotensin-convertase inhibitor intake. TRPA1 messenger RNA was more coexpressed with transcripts of tumor necrosis factor alpha than with interferon gamma. Keratinocytes, macrophages but not T cells expressed TRPA1. CONCLUSIONS: We provided evidence for the extraneuronal presence and upregulation of the proinflammatory TRPA1 receptor in buccal samples of patients with OLP. This may implicate the ion channel in the pathomechanism of OLP. PMID- 27718299 TI - Duration of reproductive lifespan and age at menarche in relation to metabolic syndrome in postmenopausal Chinese women. AB - AIM: This study aimed to assess the associations between menstrual characteristics and the prevalence of metabolic syndrome (MetS) and non-alcoholic fatty liver disease. METHODS: A cross-sectional study was conducted with a sample of 1625 postmenopausal women in China. Subjects were classified into three groups according to the tertiles of some variables related to the reproductive life. We assessed associations in multivariable-adjusted analyses, using logistic regressions. RESULTS: After adjustments for confounding factors, the odds ratios (OR) for predicting the presence of MetS increased gradually: as the years of menstruation increased (18-34 years vs 35-37 years vs 38-46 years: OR [95% confidence interval (CI)] = 1 vs 1.231 [0.942-1.610] vs 1.309 [0.985-1.740], respectively); as age at menopause increased (31-48 years vs 49-51 years vs 52-59 years: OR [95%CI] = 1 vs 1.115 [0.846-1.469] vs 1.315 [0.986-1.753], respectively); and as age at menarche decrease (11-13 years vs 14-15 years vs 16 20 years: OR [95%CI] = 1 vs 0.950 [0.728-1.240] vs 0.862 [0.610-1.119], respectively). Among the components of MetS, the highest tertile of years of menstruation was significantly associated with elevated waist circumference (OR =1.401 [95%CI = 1.092-1.798]), and elevated triglyceride (OR =1.220 [95%CI = 0.934-1.593]). Nevertheless, the association between these reproductive factors and non-alcoholic fatty liver disease was not significant. CONCLUSION: Longer duration of menstruation and earlier age at menarche were significantly associated with a higher risk of central obesity and MetS in postmenopausal Chinese women.

PMID- 27718301 TI - Embolization of the inferior mesenteric artery for post-partum hemorrhage with a vaginal laceration: A case with unusual collateral supply. AB - A 36-year-old primipara woman was referred to the interventional department for management of severe primary post-partum hemorrhage with a vaginal laceration after a normal vaginal delivery. Angiography revealed that the superior rectal branch of the inferior mesenteric artery was one of the origins of persistent vaginal bleeding following embolization of both uterine arteries. The patient was successfully treated by selective embolization without other complications. Our case report highlights that the inferior mesenteric artery should be considered as an unusual extrauterine source for post-partum hemorrhage. PMID- 27718302 TI - Evaluation of new markers for minimal residual disease monitoring in B-cell precursor acute lymphoblastic leukemia: CD73 and CD86 are the most relevant new markers to increase the efficacy of MRD 2016; 00B: 000-000. AB - BACKGROUND: Multiparametric flow cytometry (MFC) is a popular technique for minimal residual disease (MRD) analysis. However, its applicability is still limited to 90% of B-cell precursor acute lymphoblastic leukemia (BCPALL) due to two major issues, i.e. a proportion of cases do not express adequate leukemia associated immunophenotype (LAIPs) with currently used markers and drug-induced antigen modulation. Hence, the incorporation of additional reliable markers is required for the further improvement of MFC-based MRD evaluation. We studied the utility of new markers in improvising MFC-based MRD detection in BCPALL. METHODS: Expression-patterns of six new markers, i.e. CD24, CD44, CD72, CD73, CD86, and CD200 were studied in leukemic-blasts from ninety childhood BCPALL patients and in hematogones from 20 uninvolved staging bone marrow (BM) and ten postinduction non-BCPALL BM samples using eight-color MFC. The utility of these new markers in the day 35 postinduction MRD evaluation was determined. RESULTS: Frequencies of LAIPs of CD73, CD86, CD72, CD44, CD200, and CD24 in diagnostic samples were 76.7, 56.7, 55.6, 50, 28.9, and 20%, respectively. Differential expression of all new markers was highly significant (P < 0.01) between early (CD10+ CD19+ CD34+) hematogones, late (CD10+ CD19+ CD34-) hematogones and BCPALL blasts except between early hematogones and BCPALL blasts for CD200 (P = 0.1). In MRD-positive samples, CD73 showed the maximum (83%) frequency of LAIP and CD86 showed the highest (100%) stability of aberrant expression. Inclusion of CD73 and CD86 increased the applicability of MFC-MRD assay to 98.9% MRD samples. CONCLUSION: CD73 and CD86 are the most relevant markers to incorporate in the routine MRD evaluation of BCPALL. (c) 2016 International Clinical Cytometry Society. PMID- 27718298 TI - Changes in the detergent-insoluble brain proteome linked to amyloid and tau in Alzheimer's Disease progression. AB - Despite a key role of amyloid-beta (Abeta) in Alzheimer's disease (AD), mechanisms that link Abeta plaques to tau neurofibrillary tangles and cognitive decline still remain poorly understood. The purpose of this study was to quantify proteins in the sarkosyl-insoluble brain proteome correlated with Abeta and tau insolubility in the asymptomatic phase of AD (AsymAD) and through mild cognitive impairment (MCI) and symptomatic AD. Employing label-free mass spectrometry-based proteomics, we quantified 2711 sarkosyl-insoluble proteins across the prefrontal cortex from 35 individual cases representing control, AsymAD, MCI and AD. Significant enrichment of Abeta and tau in AD was observed, which correlated with neuropathological measurements of plaque and tau tangle density, respectively. Pairwise correlation coefficients were also determined for all quantified proteins to Abeta and tau, across the 35 cases. Notably, six of the ten most correlated proteins to Abeta were U1 small nuclear ribonucleoproteins (U1 snRNPs). Three of these U1 snRNPs (U1A, SmD and U1-70K) also correlated with tau consistent with their association with tangle pathology in AD. Thus, proteins that cross-correlate with both Abeta and tau, including specific U1 snRNPs, may have potential mechanistic roles in linking Abeta plaques to tau tangle pathology during AD progression. PMID- 27718303 TI - Is Alcoholics Anonymous religious, spiritual, neither? Findings from 25 years of mechanisms of behavior change research. AB - BACKGROUND: Alcoholics Anonymous (AA) is a world-wide recovery mutual-help organization that continues to arouse controversy. In large part, concerns persist because of AA's ostensibly quasi-religious/spiritual orientation and emphasis. In 1990 the United States' Institute of Medicine called for more studies on AA's effectiveness and its mechanisms of behavior change (MOBC) stimulating a flurry of federally funded research. This paper reviews the religious/spiritual origins of AA and its program and contrasts its theory with findings from this latest research. METHOD: Literature review, summary and synthesis of studies examining AA's MOBC. RESULTS: While AA's original main text ('the Big Book', 1939) purports that recovery is achieved through quasi religious/spiritual means ('spiritual awakening'), findings from studies on MOBC suggest this may be true only for a minority of participants with high addiction severity. AA's beneficial effects seem to be carried predominantly by social, cognitive and affective mechanisms. These mechanisms are more aligned with the experiences reported by AA's own larger and more diverse membership as detailed in its later social, cognitive and behaviorally oriented publications (e.g. Living Sober, 1975) written when AA membership numbered more than a million men and women. CONCLUSIONS: Alcoholics Anonymous appears to be an effective clinical and public health ally that aids addiction recovery through its ability to mobilize therapeutic mechanisms similar to those mobilized in formal treatment, but is able to do this for free over the long term in the communities in which people live.

PMID- 27718305 TI - Mass spectrometry applied to the identification of Mycobacterium tuberculosis and biomarker discovery. AB - An adequate and effective tuberculosis (TB) diagnosis system has been identified by the World Health Organization as a priority in the fight against this disease. Over the years, several methods have been developed to identify the bacillus, but bacterial culture remains one of the most affordable methods for most countries. For rapid and accurate identification, however, it is more feasible to implement molecular techniques, taking advantage of the availability of public databases containing protein sequences. Mass spectrometry (MS) has become an interesting technique for the identification of TB. Here, we review some of the most widely employed methods for identifying Mycobacterium tuberculosis and present an update on MS applied for the identification of mycobacterial species. PMID- 27718306 TI - Common congenital anomalies: Environmental causes and prevention with folic acid containing multivitamins. AB - Congenital anomalies, congenital defects, or birth defects are significant causes of death in infants. The most common congenital defects are congenital heart defects (CHDs) and neural tube defects (NTDs). Defects induced by genetic mutations, environmental exposure to toxins, or a combination of these effects can result in congenital malformations, leading to infant death or long-term disabilities. These defects produce significant mortality and morbidity in the affected individuals, and families are affected emotional and financially. Also, society is impacted on many levels. Congenital anomalies may be reduced by dietary supplements of folic acid and other vitamins. Here, we review the evidence for specific roles of toxins (alcohol, cigarette smoke) in causing common severe congenital anomalies like CHDs, NTDs, and ocular defects. We also review the evidence for beneficial effects for dietary supplementation, and highlight gaps in our knowledge, where research may contribute to additional benefits of intervention that can reduce birth defects. Extensive discussion of common severe congenital anomalies (CHDs, NTDs, and ocular defects) illustrates the effects of diet on the frequency and severity of these defects.

PMID- 27718307 TI - Sen1, the homolog of human Senataxin, is critical for cell survival through regulation of redox homeostasis, mitochondrial function, and the TOR pathway in Saccharomyces cerevisiae. AB - Mutations in the Senataxin gene, SETX are known to cause the neurodegenerative disorders, ataxia with oculomotor apraxia type 2 (AOA2), and amyotrophic lateral sclerosis 4 (ALS4). However, the mechanism underlying disease pathogenesis is still unclear. The Senataxin N-terminal protein-interaction and C-terminal RNA/DNA helicase domains are conserved in the Saccharomyces cerevisiae homolog, Sen1p. Using genome-wide expression analysis, we first show alterations in key cellular pathways such as: redox, unfolded protein response, and TOR in the yeast sen1 DeltaN mutant (N-terminal truncation). This mutant exhibited growth defects on nonfermentable carbon sources, was sensitive to oxidative stress, and showed severe loss of mitochondrial DNA. The growth defect could be partially rescued upon supplementation with reducing agents and antioxidants. Furthermore, the mutant showed higher levels of reactive oxygen species, lower UPR activity, and alterations in mitochondrial membrane potential, increase in vacuole acidity, free calcium ions in the cytosol, and resistance to rapamycin treatment. Notably, the sen1 ?N mutant showed increased cell death and shortened chronological life span. Given the strong similarity of the yeast and human Sen1 proteins, our study thus provides a mechanism for the progressive neurological disorders associated with mutations in human senataxin. PMID- 27718308 TI - Digestive fate of dietary carrageenan: Evidence of interference with digestive proteolysis and disruption of gut epithelial function. AB - SCOPE: The objective of this study was to interrogate two mechanisms by which commercial Carrageenans (E407) (CGN) may adversely affect human health: (i) Through modification of gastric proteolysis and (ii) Through affecting gut epithelial structure and function. METHODS AND RESULTS: Three commercial CGN samples with distinct zeta-potentials (stable at the pH range of 3-7 and varied with physiological levels of CaCl2 ) were mixed with milk, soy or egg protein isolates, then subjected to a semi-dynamic in vitro digestion model and analyzed by SDS-PAGE. This revealed varying levels of interference with gastric digestive proteolysis and a significant decrease in pepsin activity. Further, a Caco-2 cell model was used to explore various effects of physiologically digested CGN (pdCGN) on various epithelial cell functions and characteristics. Samples of pdCGN (0.005 0.5 mg/mL) affected the epithelial barrier function, including redistribution of the tight-junction protein Zonula Occludens (Zo)-1, changes in cellular F-actin architecture and increased monolayer permeability to the transfer of macromolecules. Moreover, pdCGN induced elevation in the levels of the pro inflammatory IL-8 receptor CXCR1. CONCLUSION: This work raises the possibility that CGN may reduce protein and peptide bioaccessibility, disrupt normal epithelial function, promote intestinal inflammation, and consequently compromise consumer health. PMID- 27718309 TI - Band 3 nullVIENNA , a novel homozygous SLC4A1 p.Ser477X variant causing severe hemolytic anemia, dyserythropoiesis and complete distal renal tubular acidosis. AB - We describe the second patient with anionic exchanger 1/band 3 null phenotype (band 3 nullVIENNA ), which was caused by a novel nonsense mutation c.1430C>A (p.Ser477X) in exon 12 of SLC4A1. We also update on the previous band 3 nullCOIMBRA patient, thereby elucidating the physiological implications of total loss of AE1/band 3. Besides transfusion-dependent severe hemolytic anemia and complete distal renal tubular acidosis, dyserythropoiesis was identified in the band 3 nullVIENNA patient, suggesting a role for band 3 in erythropoiesis. Moreover, we also, for the first time, report that long-term survival is possible in band 3 null patients. PMID- 27718310 TI - Protection against vaccine preventable diseases in children treated for acute lymphoblastic leukemia. AB - BACKGROUND: The objective of this retrospective study was to assess protection against vaccine preventable diseases (VPDs) in children treated for acute lymphoblastic leukemia (ALL). PROCEDURE: Clinical characteristics and vaccination records were collected. Antibodies against VPDs were measured after completion of chemotherapy and after a booster dose of vaccine. Immunization status of household members was evaluated. RESULTS: Sixty children were included. Median interval between the end of chemotherapy and enrolment in the study was 13 months (range 1-145). At ALL diagnosis, 81.3% of the children were up to date with their vaccination schedule. This proportion decreased to 52.9% at enrolment. Among the parents, 21% were up to date with their immunization schedule and 42% had received seasonal influenza vaccination. After chemotherapy, less than 50% of the patients were seroprotected against tetanus, diphtheria, polio 3, Haemophilus influenzae type b (Hib), and mumps and no more than 80% were seroprotected against polio 1 and 2, measles, rubella, and varicella. After a booster dose of vaccine, the rate of protection increased to over 90% for each of the following antigens: TT, DT, polio 1, Hib, measles, and rubella. Nevertheless, polio 3, mumps, and varicella-zoster virus antibodies titers/concentrations remained below seroprotective thresholds in over 20% of the patients. CONCLUSIONS: After chemotherapy for ALL, most of the children were not protected against VPDs. As the majority mounted a robust response to booster vaccines, efforts need to be done to improve protection against VPDs by implementing a systematic vaccine booster schedule. This could also be helped by reinforcing household members' immunization. PMID- 27718311 TI - A rice jacalin-related mannose-binding lectin gene, OsJRL, enhances Escherichia coli viability under high salinity stress and improves salinity tolerance of rice. AB - Salinity, which is one of the most common abiotic stresses, may severely affect plant productivity and quality. Although plant lectins are thought to play important roles in plant defense signaling during pathogen attack, little is known about the contribution of plant lectins to stress resistance. We cloned and functionally characterized a rice jacalin-related mannose-binding lectin gene, OsJRL, from rice 'Nipponbare'. We analyzed the expression patterns of OsJRL under various stress conditions in rice. Furthermore, we overexpressed OsJRL in Escherichia coli and rice. The cDNA of OsJRL contained a 438 bp open reading frame, which encodes a polypeptide of 145 amino acids. OsJRL was localized in the nucleus and cytoplasm. Real time PCR analyses revealed that OsJRL expression showed tissue specificity in rice and was upregulated under diverse stresses, namely salt, drought, cold, heat and abscisic acid treatments. Overexpression of OsJRL in E. coli enhanced cell viability and dramatically improved tolerance of high salinity. Overexpression of OsJRL in rice also enhanced salinity tolerance and increased the expression levels of a number of stress-related genes, including three LEA (late embryogenesis abundant proteins) genes (OsLEA19a, OsLEA23 and OsLEA24), three Na+ transporter genes (OsHKT1;3, OsHKT1;4 and OsHKT1;5) and two DREB genes (OsDREB1A and OsDREB2B). Based on these results, we suggest that OsJRL plays an important role in cell protection and stress signal transduction. PMID- 27718312 TI - Extracting histones for the specific purpose of label-free MS. AB - Extracting histones from cells is the first step in studies that aim to characterize histones and their post-translational modifications (hPTMs) with MS. In the last decade, label-free quantification is more frequently being used for MS-based histone characterization. However, many histone extraction protocols were not specifically designed for label-free MS. While label-free quantification has its advantages, it is also very susceptible to technical variation. Here, we adjust an established histone extraction protocol according to general label-free MS guidelines with a specific focus on minimizing sample handling. These protocols are first evaluated using SDS-PAGE. Hereafter, a selection of extraction protocols was used in a complete histone workflow for label-free MS. All protocols display nearly identical relative quantification of hPTMs. We thus show that, depending on the cell type under investigation and at the cost of some additional contaminating proteins, minimizing sample handling can be done during histone isolation. This allows analyzing bigger sample batches, leads to reduced technical variation and minimizes the chance of in vitro alterations to the hPTM snapshot. Overall, these results allow researchers to determine the best protocol depending on the resources and goal of their specific study. Data are available via ProteomeXchange with identifier PXD002885. PMID- 27718313 TI - Abscisic acid regulates seed germination of Vellozia species in response to temperature. AB - The relationship between the phytohormones, gibberellin (GA) and abscisic acid (ABA) and light and temperature on seed germination is still not well understood. We aimed to investigate the role of the ABA and GA on seed germination of Vellozia caruncularis, V. intermedia and V. alutacea in response to light/dark conditions on different temperature. Seeds were incubated in GA (GA3 or GA4 ) or ABA and their respective biosynthesis inhibitors (paclobutrazol - PAC, and fluridone - FLU) solutions at two contrasting temperatures (25 and 40 degrees C). Furthermore, endogenous concentrations of active GAs and those of ABA were measured in seeds of V. intermedia and V. alutacea during imbibition/germination. Exogenous ABA inhibited the germination of Vellozia species under all conditions tested. GA, FLU and FLU + GA3 stimulated germination in the dark at 25 degrees C (GA4 being more effective than GA3 ). PAC reduced seed germination in V. caruncularis and V. alutacea, but did not affect germination of V. intermedia at 40 degrees C either under light or dark conditions. During imbibition in the dark, levels of active GAs decreased in the seeds of V. intermedia, but were not altered in those of V. alutacea. Incubation at 40 degrees C decreased ABA levels during imbibition in both V. caruncularis and V. alutacea. We conclude that the seeds of Vellozia species studied here require light or high temperature to germinate and ABA has a major role in the regulation of Vellozia seed germination in response to light and temperature. PMID- 27718314 TI - The assessment of data sources for influenza virologic surveillance in New York State. AB - BACKGROUND: Following the 2013 USA release of the Influenza Virologic Surveillance Right Size Roadmap, the New York State Department of Health (NYSDOH) embarked on an evaluation of data sources for influenza virologic surveillance. OBJECTIVE: To assess NYS data sources, additional to data generated by the state public health laboratory (PHL), which could enhance influenza surveillance at the state and national level. METHODS: Potential sources of laboratory test data for influenza were analyzed for quantity and quality. Computer models, designed to assess sample sizes and the confidence of data for statistical representation of influenza activity, were used to compare PHL test data to results from clinical and commercial laboratories, reported between June 8, 2013 and May 31, 2014. RESULTS: Sample sizes tested for influenza at the state PHL were sufficient for situational awareness surveillance with optimal confidence levels, only during peak weeks of the influenza season. Influenza data pooled from NYS PHLs and clinical laboratories generated optimal confidence levels for situational awareness throughout the influenza season. For novel influenza virus detection in NYS, combined real-time (rt) RT-PCR data from state and regional PHLs achieved >=85% confidence during peak influenza activity, and >=95% confidence for most of low season and all of off-season. CONCLUSIONS: In NYS, combined data from clinical, commercial, and public health laboratories generated optimal influenza surveillance for situational awareness throughout the season. Statistical confidence for novel virus detection, which is reliant on only PHL data, was achieved for most of the year. PMID- 27718315 TI - Comparison by multilocus variable-number tandem repeat analysis and antimicrobial resistance among atypical enteropathogenic Escherichia coli strains isolated from food samples and human and animal faecal specimens. AB - AIM: This study assessed whether multilocus variable-number tandem repeat analysis (MLVA) and antimicrobial susceptibility testing discriminated diarrhoeagenic atypical enteropathogenic Escherichia coli (aEPEC) from aEPEC indigenous to domestic animals or healthy people. METHODS AND RESULTS: MLVA genotyping of 142 aEPEC strains isolated from foods and faecal samples of domestic animals and humans revealed 126 distinct MLVA profiles that distributed to four clusters, yielding a Simpson's index of diversity (D) of 99.8%. Cluster 2 included 87% of cattle isolates and 67% of patient isolates. The plurality (15/34, 44%) of strains from healthy humans mapped to Cluster 1, while half (18/41, 44%) of the swine strains belonged to Cluster 4. Testing for antimicrobial susceptibility revealed that 52 strains (37%) of aEPEC were resistant to one or more agents; only 10 strains (7%) exhibited resistance to more than three agents. Strains isolated from swine or food exhibited a wider variety of resistance phenotypes than bovine or human strains. CONCLUSIONS: MLVA assigned the aEPEC isolates from cattle and patients to Cluster 2, distinct from aEPEC from other sources. Hog yards may be a larger source of drug-resistant strains than are cattle ranches. SIGNIFICANCE AND IMPACT OF THE STUDY: MLVA suggests that human diarrhoeagenic aEPEC are derived from cattle and are distinct from strains carried by healthy people and other animals. Cattle appear to be reservoirs of human diarrhoeagenic aEPEC.

AB - Population genetic studies in tropical plants are often challenging because of limited information on taxonomy, phylogenetic relationships and distribution ranges, scarce genomic information and logistic challenges in sampling. We describe a strategy to develop robust and widely applicable genetic markers based on a modest development of genomic resources in the ancient tropical tree species Symphonia globulifera L.f. (Clusiaceae), a keystone species in African and Neotropical rainforests. We provide the first low-coverage (11X) fragmented draft genome sequenced on an individual from Cameroon, covering 1.027 Gbp or 67.5% of the estimated genome size. Annotation of 565 scaffolds (7.57 Mbp) resulted in the prediction of 1046 putative genes (231 of them containing a complete open reading frame) and 1523 exact simple sequence repeats (SSRs, microsatellites). Aligning a published transcriptome of a French Guiana population against this draft genome produced 923 high-quality single nucleotide polymorphisms. We also preselected genic SSRs in silico that were conserved and polymorphic across a wide geographical range, thus reducing marker development tests on rare DNA samples. Of 23 SSRs tested, 19 amplified and 18 were successfully genotyped in four S. globulifera populations from South America (Brazil and French Guiana) and Africa (Cameroon and Sao Tome island, FST = 0.34). Most loci showed only population specific deviations from Hardy-Weinberg proportions, pointing to local population effects (e.g. null alleles). The described genomic resources are valuable for evolutionary studies in Symphonia and for comparative studies in plants. The methods are especially interesting for widespread tropical or endangered taxa with limited DNA availability. PMID- 27718317 TI - The development of SRM assays is transforming proteomics research. AB - Bottom-up targeted proteomics using SRM is a powerful analytical technology, but it requires the development of SRM assays, which is a complex procedure. Whereas proteome-wide SRM assays have recently been developed for a small number of species, this is not so for the mouse. In this issue, Percy et al. report the development of hundreds of mouse SRM assays. Their development required shotgun MS to identify proteotypic peptides, synthesis, and LC-MS characterization of peptide standards, and interlaboratory SRM to robustly assess the quality of the assays. The resulting SRM assays are intended to be used to analyze mouse plasma and cardiac tissue, primarily for cardiovascular disease and cancer research. PMID- 27718318 TI - Local paleoenvironmental controls on the carbon-isotope record defining the Bitter Springs Anomaly. AB - Large magnitude (>100/00) carbon-isotope (delta13 C) excursions recorded in carbonate-bearing sediments are increasingly used to monitor environmental change and constrain the chronology of the critical interval in the Neoproterozoic stratigraphic record that is timed with the first appearance and radiation of metazoan life. The ~100/00 Bitter Springs Anomaly preserved in Tonian-aged (1000 720 Ma) carbonate rocks in the Amadeus Basin of central Australia has been offered as one of the best preserved examples of a primary marine delta13 C excursion because it is regionally reproducible and delta13 C values covary in organic and carbonate carbon arguing against diagenetic exchange. However, here we show that delta13 C values defining the excursion coincide with abrupt lithofacies changes between regularly cyclic grainstone and microbial carbonates, and desiccated red bed mudstones with interbedded evaporite and dolomite deposits, recording local environmental shifts from restricted marine conditions to alkaline lacustrine and playa settings that preserve negative (-40/00) and positive (+60/00) delta13 C values, respectively. The stratigraphic delta13 C pattern in both organic and carbonate carbon recurs within the basin in a similar way to associated sedimentary facies, reflecting the linkage of local paleoenvironmental conditions and delta13 C values. These local excursions may be time transgressive or record a relative sea-level influence manifest through exposure of sub-basins isolated by sea-level fall below shallow sills, but are independent of secular seawater variation. As the shallow intracratonic setting of the Bitter Springs Formation is typical of other Neoproterozoic carbonate successions used to construct the present delta13 C seawater record, it identifies the potential for local influences on delta13 C excursions that are neither diagenetic nor representative of the global exogenic cycle. PMID- 27718319 TI - Measuring cancer-specific child adjustment difficulties: Development and validation of the Children's Oncology Child Adjustment Scale (ChOCs). AB - BACKGROUND: Childhood cancer is associated with child adjustment difficulties including, eating and sleep disturbance, and emotional and other behavioral difficulties. However, there is a lack of validated instruments to measure the specific child adjustment issues associated with pediatric cancer treatments. The aim of this study was to develop and evaluate the reliability and validity of a parent-reported, child adjustment scale. PROCEDURE: One hundred thirty-two parents from two pediatric oncology centers who had children (aged 2-10 years) diagnosed with cancer completed the newly developed measure and additional measures of child behavior, sleep, diet, and quality of life. Children were more than 4 weeks postdiagnosis and less than 12 months postactive treatment. Factor structure, internal consistency, and construct (convergent) validity analyses were conducted. RESULTS: Principal component analysis revealed five distinct and theoretically coherent factors: Sleep Difficulties, Impact of Child's Illness, Eating Difficulties, Hospital-Related Behavior Difficulties, and General Behavior Difficulties. The final 25-item measure, the Children's Oncology Child Adjustment Scale (ChOCs), demonstrated good internal consistency (alpha = 0.79-0.91). Validity of the ChOCs was demonstrated by significant correlations between the subscales and measures of corresponding constructs. CONCLUSION: The ChOCs provides a new measure of child adjustment difficulties designed specifically for pediatric oncology. Preliminary analyses indicate strong theoretical and psychometric properties. Future studies are required to further examine reliability and validity of the scale, including test-retest reliability, discriminant validity, as well as change sensitivity and generalizability across different oncology samples and ages of children. The ChOCs shows promise as a measure of child adjustment relevant for oncology clinical settings and research purposes. PMID- 27718320 TI - Hypertension and early menopause after the use of assisted reproductive technologies in women aged 43 years or older: Long-term follow-up study. AB - AIM: The aim of this study was to investigate the long-term consequences to women's health and the onset of menopause in healthy women of advanced reproductive age who conceived by assisted reproductive technologies (ART). METHODS: Healthy women who conceived by ART (72) and controls (80) were selected among 320 women >= 43 years, who delivered between January 2010 and December 2011 in the Department of Gynecological and Obstetrical Sciences and Urological Sciences of "Sapienza" University of Rome. Body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), and presence of hypertension and diabetes were analyzed at three days, six months, and three years after delivery. The onset of menopause was analyzed after three years. RESULTS: In the ART group, SBP, DBP and hypertension were higher at three days, six months, and three years after delivery. Menopausal age was significantly lower. CONCLUSION: The impact of ART in healthy women of advanced reproductive age in the years after delivery is not limited to the possible development of cardiovascular risk factors, such as hypertension, but can also influence the age of onset of menopause. PMID- 27718321 TI - Biliary diseases as main causes of pyogenic liver abscess caused by extended spectrum beta-lactamase-producing Enterobacteriaceae. AB - BACKGROUND & AIMS: Little is known about aetiology and morbidity and clinical characteristics of pyogenic liver abscess caused by extended-spectrum beta lactamase-producing Enterobacteriaceae. METHODS: An analysis between pyogenic liver abscess patients caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae isolates and those caused by non-extended-spectrum beta lactamase-producing Enterobacteriaceae was performed. RESULTS: Among 817 pyogenic liver abscess patients, there were 176 patients (21.5%) with pyogenic liver abscess of biliary origin, and 67 pyogenic liver abscess patients (8.2%) caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae isolates (mainly Escherichia coli and Klebsiella pneumoniae). Of 176 pyogenic liver abscess patients related to biliary disorders, there were 48 pyogenic liver abscess patients (27.3%) caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae. Within 67 pyogenic liver abscess patients caused by Enterobacteriaceae expressing extended-spectrum beta-lactamases, the occurrences of 48 pyogenic liver abscess patients (71.6%) were associated with biliary disorders. When compared with pyogenic liver abscess patients caused by non extended-spectrum beta-lactamase-producing Enterobacteriaceae, there were significantly greater incidences of polymicrobial infections, bacteremia, pulmonary infection, recurrence and death in pyogenic liver abscess patients caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae. Carbapenems remain mainstay drugs against extended-spectrum beta-lactamase producing E. coli and K. pneumoniae. Independent risk factors for occurrence of pyogenic liver abscess caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae were biliary disorders including extra- and intrahepatic cholangiolithiasis and an abnormal bilioenteric communication between bile and gut, a treatment history of malignancy such as operation and chemotherapy, pulmonary infection, and diabetes mellitus. CONCLUSIONS: Pyogenic liver abscess caused by extended-spectrum beta-lactamase-producing Enterobacteriaceae isolates mainly occurs in patients with biliary disorders or with a treatment history of malignancy. The mainstay of treatment remains carbapenems in combination with adequate aspiration or drainage. PMID- 27718322 TI - Longitudinal mutational analysis of a cerebellar pilocytic astrocytoma recurring as a ganglioglioma. AB - A cerebellar pilocytic astrocytoma (PA) in a child recurred first with a PA histology and then with features of a ganglioglioma (GG). Molecular genetic analyses of the tumors confirmed a BRAF V600E mutation in all. They also all harbored a T202M mutation in ERK1, a kinase downstream of BRAF that is implicated in glial versus neuronal differentiation. The GG sample contained several variants that were not present in the PA samples; in particular, it had a truncating mutation in MAP2. These findings not only underscore the role of BRAF as oncogenic driver but also suggest that other genes may influence tumor morphology.

AB - Childhood-onset chronic and refractory cytopenias are rare and may be genetic in etiology. We report three pediatric cases of severe autoimmune thrombocytopenia or anemia associated with growth retardation and spastic diplegia with intracranial calcification. The identification of platyspondyly and metaphyseal lesions suggested a potential diagnosis of spondyloenchondrodysplasia (SPENCD), which was confirmed with the identification of biallelic ACP5 mutations. Two patients demonstrated elevated serum interferon alpha levels. Our report highlights ACP5-associated disease as a cause of childhood-onset autoimmune cytopenia, particularly combined with growth retardation and/or spasticity. Furthermore, a role for type I interferon in the pathogenesis of autoimmune cytopenias is supported. PMID- 27718325 TI - First Report on Rare Unifloral Honey of Endemic Moltkia petraea (Tratt.) Griseb. from Croatia: Detailed Chemical Screening and Antioxidant Capacity. AB - Rare Moltkia petraea (Tratt.) Griseb. honey from Croatia was first time characterised. The spectrophotometric assays on CIE L*a*b*Cab *hab degrees colour coordinates, total phenol content and antioxidant capacity (FRAP, CUPRAC, DPPH* and ABTS*+ assays) determined higher honey values generally close to dark honeys ranges. Headspace solid-phase microextraction (HS-SPME) on two fibres after GC-FID and GC/MS revealed the major compounds 2-phenylacetaldehyde (12.8%; 15.6%), benzaldehyde (11.1%; 10.0%), octane (9.3%; 7.6%), nonane, propan-2-one, pentan-2-one, pentanal and nonanal (4.9%; 14.5%). Ultrasonic solvent extraction (USE) mainly isolated non-specific higher molecular compounds characteristic of the comb environment. Targeted HLPC-DAD analysis of the honey determined higher concentration of phenylalanine (212.08 mg/kg) and lumichrome (16.25 mg/kg) along with tyrosine and kojic acid. The headspace composition (chemical fingerprint) and high concentration of lumichrome can be considered particular for M. petraea honey. PMID- 27718326 TI - Potential use of metabolic breath tests to assess liver disease and prognosis: has the time arrived for routine use in the clinic? AB - The progression of liver disease may be unique among organ system diseases in that progressive fibrosis compromises not only the sufficiency of hepatocyte mass but also impairs blood flow to the liver, resulting in porto-systemic shunting. Although liver biopsy as an assessment of fibrosis has become the key biomarker of and target for new therapies, it is invasive and subject to sampling error, and cannot quantify metabolic function or porto-systemic shunting. Measurement of the hepatic venous pressure gradient accommodates some of the deficiencies of biopsy but requires expertise not widely available and misses minor changes in hepatocellular mass and thereby information about metabolic function. Thus, an unmet need in clinical hepatology remains unfulfilled: a noninvasive biomarker which quantitates both the hepatocellular insufficiency and porto-systemic shunting inherent in progressive hepatic fibrosis. Ideally, such a biomarker should correlate with clinical endpoints including liver-related survival and cirrhotic complications, be performed at the point-of-care, and be affordable and easy to use. This review, an expert opinion, summarizes background and recent data suggesting that metabolic breath tests may now meet these requirements and have a valid place in clinical hepatology to supplant the time-honoured assessment of hepatic fibrosis. PMID- 27718328 TI - RNA-Seq identifies redox balance related gene expression alterations under acute cadmium exposure in yeast. AB - The nonessential metal cadmium can cause cell toxicity and is associated with a range of human diseases including cardiovascular diseases, neurodegenerative diseases and cancers. In this study, cadmium-induced global gene expression profile of yeast was obtained using RNA Sequencing (RNA-Seq) and further analyzed by means of informatics and experiments. A total of 912 Differentially Expressed Genes (DEGs) (FDR of q < 0.01), including 415 Cd-inducible and 497 Cd-repressed genes were identified. Based on the DEGs, 25 cadmium responsive Clusters of Orthologous Group (COG) and three types of cadmium-induced Gene Ontology (GO) including cellular components, molecular functions and biological processes were analyzed in details. Thereafter, 79 Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways under cadmium exposure were assigned. Collectively, 108 redox balance related genes were extracted under cadmium exposure. Meanwhile, cadmium exposure lowered cellular Mitochondrial Membrane Potential (MMP) and increased Reactive Oxygen Species (ROS) levels significantly in the context of mitochondrial dysfunction. Furthermore, cadmium exposure increased cellular GSH levels and decreased GSSG levels and also lowered GSSG/GSH ratio of cells, which supports experimentally our claim that the redox balance is the primary mechanism for cadmium toxicity. The results present in this study may provide new strategies for cadmium detoxification and prevention or therapies of cadmium associated diseases. PMID- 27718327 TI - The newborn human NK cell repertoire is phenotypically formed but functionally reduced. AB - BACKGROUND: Infection is a leading cause of death worldwide in babies under 1 month of age. Better vaccines and therapeutics are desperately needed for this vulnerable population. METHODS: Because newborns rely heavily on the innate immune system, we evaluated cell phenotype and function of some of the earliest cellular responders during infection, natural killer (NK) cells. We used mass cytometry to provide a comprehensive comparison of NK cells from umbilical cord blood and adult peripheral blood. RESULTS: In unsupervised analyses, including viSNE and principal component analysis, the structure of the cord blood and adult NK cell repertoires are highly similar, distinguishable mainly by maturity related markers expressed on rare subpopulations of cells. However, in functional analyses, cord blood NK cells show reduced degranulation and cytokine production following target recognition, as well as antibody-dependent cell-mediated cytotoxicity and apoptosis induction in targets. CONCLUSIONS: These findings show that the structure of the NK cell repertoire is intact at birth, suggesting great potential for vaccine and therapeutic strategies targeting this cell population.

AB - BACKGROUND: Tomato bacterial wilt caused by Ralstonia solanacearum poses a serious threat to tomato production. However, no effective control measures are available. In this study, the bactericide Saisentong was combined with an effective biological control agent, Bacillus subtilis B-001, to control tomato bacterial wilt under greenhouse and field conditions. RESULTS: Growth of B-001 in vitro was unaffected by Saisentong. In greenhouse experiments, the combined application of B-001 and Saisentong via root irrigation or spray resulted in better disease control compared with either agent alone. In two field trials, at a Saisentong concentration of 400 or 500 mg kg-1 , the combined treatment was more effective than expected and showed a synergistic effect. A lower concentration of Saisentong (200 or 300 mg kg-1 ) in combination with B-001 resulted in an antagonistic effect. However, disease control was significantly greater compared with either treatment alone. CONCLUSION: The combination of Saisentong and B-001 effectively controls tomato bacterial wilt. The integrated strategy represents a promising new tool to control this disease. (c) 2016 Society of Chemical Industry. PMID- 27718331 TI - Ovarian clear cell carcinoma with plasma cell-rich inflammatory stroma: Cytological Findings of a Case. AB - We report a case of clear cell carcinoma (CCC) of the ovary with plasma cell-rich inflammatory stroma, a recently proposed subtype of CCC, and present the cytological findings. The patient was a 48-year-old woman, who was incidentally found to have a right ovarian tumor during the preoperative work-up for an early stage adenocarcinoma of the uterine cervix. Cytological examination of an imprint smear of the ovarian tumor and peritoneal washing revealed solid cell clusters of irregular, often dendritic shapes, which were intermingled with many inflammatory cells. "Raspberry bodies" were not found. Histopathological examination of the extirpated ovarian tumor showed the features of CCC with plasma cell-rich inflammatory stroma. This subtype of ovarian CCC poses cytological and histological diagnostic problems, and its differentiation from dysgerminoma is often difficult, because it mostly lacks the hyaline or mucoid stroma. Irregularly shaped clusters of large polyhedral cells, coarsely clumped nuclear chromatin, and plasma cell-rich inflammatory infiltrates suggest CCC, but the cytological differences between dysgerminoma and CCC are often subtle, and immunohistochemical examinations for cytokeratin 7 or epithelial membrane antigen may be necessary.

AB - The role and importance of pigs and pork as sources of zoonotic hepatitis E virus (HEV) has been debated in Canada and abroad for over 20 years. To further investigate this question, we compiled data to populate a risk profile for HEV in pigs or pork in Canada. We organized the risk profile (RP) using the headings prescribed for a foodborne microbial risk assessment and used research synthesis methods and inputs wherever possible in populating the fields of this RP. A scoping review of potential public health risks of HEV, and two Canadian field surveys sampling finisher pigs, and retail pork chops and pork livers, provided inputs to inform this RP. We calculated summary estimates of prevalence using the Comprehensive Meta-analysis 3 software, employing the method of moments. Overall, we found the incidence of sporadic locally acquired hepatitis E in Canada, compiled from peer-reviewed literature or from diagnosis at the National Microbiology Laboratory to be low relative to other non-endemic countries. In contrast, we found the prevalence of detection of HEV RNA in pigs and retail pork livers, to be comparable to that reported in the USA and Europe. We drafted risk categories (high/medium/low) for acquiring clinical hepatitis E from exposure to pigs or pork in Canada and hypothesize that the proportion of the Canadian population at high risk from either exposure is relatively small. PMID- 27718332 TI - Plant community, geographic distance and abiotic factors play different roles in predicting AMF biogeography at the regional scale in northern China. AB - Arbuscular mycorrhizal fungi (AMF) are ubiquitous mutualists of terrestrial plants and play key roles in regulating various ecosystem processes, but little is known about AMF biogeography at regional scale. This study aims at exploring the key predictors of AMF communities across a 5000-km transect in northern China. We determined the soil AMF species richness and community composition at 47 sites representative of four vegetation types (meadow steppe, typical steppe, desert steppe and desert) and related them to plant community characteristics, abiotic factors and geographic distance. The results showed that soil pH was the strongest predictor of AMF richness and phylogenetic diversity. However, abiotic factors only have a low predictive effect on AMF community composition or phylogenetic patterns. By contrast, we found a significant relationship between community composition of AMF and plants, which was a surprising result given the extent of heterogeneity in the plant community across this transect. Moreover, the geographic distance predominantly explained the AMF phylogenetic structure, implying that history evolutionary may play a role in shaping AMF biogeographic patterns. This study highlighted the different roles of main factors in predicting AMF biogeography, and bridge landscape-scale studies to more recent global-scale efforts.

AB - Pleuropulmonary blastoma (PPB) is a rare primitive intrathoracic malignant neoplasm that occurs almost exclusively in children and adolescents. PPB is classified into three types according to the presence of cystic and solid areas. We report a case of PPB with an intraocular metastasis diagnosed by fine needle aspiration (FNA): 3-year-old female was treated for type II PPB by neoadjuvant chemotherapy and surgery. Four years later, she presented with an intraocular lesion. To differentiate between metastasis or other malignancy, a transcleral FNA was performed and showed two cellular populations represented by roundish malignant cells and spindle-shaped cells. The patient was treated with chemotherapy and diode laser ablation. A year later, the patient had enucleation and rare residual cells were found on the histological specimen. Patient remains disease-free 66 months after the last surgical treatment. Diagn. Cytopathol. 2017;45:156-160. (c) 2016 Wiley Periodicals, Inc. PMID- 27718334 TI - Getting at the "what" and the "how" in symbiosis. AB - Symbioses are ubiquitous and have had a tremendous impact on the evolution of life on the planet. Indeed, endosymbiosis lead to the generation of the first eukaryotic cell and from that point onwards, eukaryotes have interacted with the other domains of life, sometimes forming persistent and necessary relationships that span generations. However, because the majority of hosts and symbionts are not easily manipulated, the intricate details of these symbioses, an understanding of the molecular underpinnings of these interactions, have not been elucidated. It is difficult to ask questions about the details of a host-microbe symbiosis if either member cannot be cultured, genetically manipulated, or even housed in a laboratory. Several technological advances in recent years may address these difficulties, making it easier for researchers to ask mechanistic questions in symbiotic systems. PMID- 27718335 TI - PSMC (pairwise sequentially Markovian coalescent) analysis of RAD (restriction site associated DNA) sequencing data. AB - The pairwise sequentially Markovian coalescent (PSMC) method uses the genome sequence of a single individual to estimate demographic history covering a time span of thousands of generations. Although originally designed for whole-genome data, we here use simulations to investigate its applicability to reference genome-aligned restriction site associated DNA (RAD) data. We find that RAD data can potentially be used for PSMC analysis, but at present with limitations. The key factor is the proportion (p) of the genome that the RAD data covers. In our simulations, a proportion of 10% can still retain a substantial amount of coalescent information, whereas for 1% estimation becomes unreliable. The performance depends strongly on mutation rate (MU) and recombination rate (r) and is proportional to MU*p/r. When the value of this term is low, increasing the amount of data and number of iterations helps restoring the power of the estimation. We subsequently analyse one whole-genome-sequenced and 17 RAD sequenced three-spined sticklebacks (Gasterosteus aculeatus) from a lake in Greenland. The whole-genome sequence suggests a relatively recent expansion and decline within ca. 4000-40 000 generations ago, possibly reflecting postglacial expansion and founding of the lake population. RAD data, where chromosomes from 10 individuals are combined, identify a similar pattern. Our study provides guidance about the use of PSMC analysis and suggests measures that can improve its utility for RAD data. Finally, the study shows that RAD loci in general contain coalescent information that can be used for developing more targeted methods.

AB - This study describes the molecular characterization of 47 foot-and-mouth disease (FMD) viruses recovered from field outbreaks in Nigeria between 2007 and 2014. Antigen ELISA of viral isolates was used to identify FMD virus serotypes O, A and SAT 2. Phylogenetic analyses of VP1 nucleotide sequences provide evidence for the presence of multiple sublineages of serotype SAT 2, and O/EAST AFRICA 3 (EA-3) and O/WEST AFRICA topotypes in the country. In contrast, for serotype A, a single monophyletic cluster of viruses has persisted within Nigeria (2009-2013). These results demonstrate the close genetic relatedness of viruses in Nigeria to those from other African countries, including the first formal characterization of serotype O/EA-3 viruses in Nigeria. The introductions and persistence of certain viral lineages in Nigeria may reflect transmission patterns via nomadic pastoralism and animal trade. Continuous monitoring of field outbreaks is necessary to dissect the complexity of FMD epidemiology in sub-Saharan Africa. PMID- 27718338 TI - Opossum peptide that can neutralize rattlesnake venom is expressed in Escherichia coli. AB - An eleven amino acid ribosomal peptide was shown to completely neutralize Western Diamondback Rattlesnake (Crotalus atrox) venom in mice when a lethal dose of the venom was pre-incubated with the peptide prior to intravenous injection. We have expressed the peptide as a concatenated chain of peptides and cleaved them apart from an immobilized metal affinity column using a protease. After ultrafiltration steps, the mixture was shown to partially neutralize rattlesnake venom in mice. Preliminary experiments are described here that suggest a potential life-saving therapy could be developed. To date, no recombinant therapies targeting cytotoxic envenomation have been reported.

AB - Porcine deltacoronavirus (PDCoV) was detected by RT-PCR in 12 of 97 (12.4%) intestinal samples collected during 2015 from piglets with diarrhoea in Thailand, Vietnam and Lao PDR. Spike, membrane and nucleocapsid genes were characterized, and phylogenetic analyses demonstrated that PDCoV isolates from Thai and Lao PDR form a novel cluster, separated from US and China isolates, but relatively were more closely related to China PDCoV than US isolates. Vietnam PDCoVs, however, were grouped together with US PDCoV. The analyses of amino acid changes suggested that they were from different lineage. PMID- 27718340 TI - A trend toward smaller optical angles and medial-ocular distance in schizophrenia spectrum, but not in bipolar and major depressive disorders. AB - Minor physical anomalies (MPAs) are subtle signs of fetal developmental abnormalities that have been considered to be among the most replicated risk markers for schizophrenia-spectrum disorders. However, quantitative approaches are needed to measure craniofacial MPAs. The present study adopted an imaging based quantitative approach to examine craniofacial MPAs across the spectrum of schizophrenia and affective disorders, to address their sensitivity and specificity. We sampled 31 patients with schizophrenia, 30 of their unaffected relatives, and 30 individuals with schizotypal personality traits, as well as 37 non-schizotypal controls. We also examined 17 patients with bipolar disorder and 19 patients with major depressive disorder. Five craniofacial MPAs were measured on anterior-posterior commissure-aligned T1-weighted images of an individual's native brain space: medial-ocular distance, lateral-ocular distance, optical angle, maximum skull length, and skull-base width. Compared to non-schizotypal controls, patients with schizophrenia and their relatives showed a trend toward having smaller optical angles and medial-ocular distance, while no difference was found in patients with bipolar or major depressive disorders, suggesting some degree of specificity to schizophrenia. Our approach may benefit future research on craniofacial MPAs as risk markers for schizophrenia-spectrum disorders, and may eventually be useful in strategies to enhance risk stratification using multiple risk markers. PMID- 27718339 TI - Recent advances in immobilization strategies for glycosidases. AB - Glycans play important biological roles in cell-to-cell interactions, protection against pathogens, as well as in proper protein folding and stability, and are thus interesting targets for scientists. Although their mechanisms of action have been widely investigated and hypothesized, their biological functions are not well understood due to the lack of deglycosylation methods for large-scale isolation of these compounds. Isolation of glycans in their native state is crucial for the investigation of their biological functions. However, current enzymatic and chemical deglycosylation techniques require harsh pretreatment and reaction conditions (high temperature and use of detergents) that hinder the isolation of native glycan structures. Indeed, the recent isolation of new endoglycosidases that are able to cleave a wider variety of linkages and efficiently hydrolyze native proteins has opened up the opportunity to elucidate the biological roles of a higher variety of glycans in their native state. As an example, our research group recently isolated a novel Endo-beta-N acetylglucosaminidase from Bifidobacterium longum subsp. infantis ATCC 15697 (EndoBI-1) that cleaves N-N'-diacetyl chitobiose moieties found in the N-linked glycan (N-glycan) core of high mannose, hybrid, and complex N-glycans. This enzyme is also active on native proteins, which enables native glycan isolation, a key advantage when evaluating their biological activities. Efficient, stable, and economically viable enzymatic release of N-glycans requires the selection of appropriate immobilization strategies. In this review, we discuss the state-of the-art of various immobilization techniques (physical adsorption, covalent binding, aggregation, and entrapment) for glycosidases, as well as their potential substrates and matrices.

AB - Time perspective is a fundamental dimension of the psychological time construct, with a pervasive and powerful influence on human behavior. However, the developmental trajectory of time perspective across a human lifespan remains unclear. The current study aimed to portray the developmental trajectory of all dimensions of time perspectives from children to older adults in a large sample. A total of 1,901 individuals (aged 9-84 years) completed measures of time perspective. They were then divided into five age groups: children, teenagers, young adults, middle-aged adults, and older adults. Results suggested that each time perspective showed a unique developmental pattern across the lifespan. Moreover, perceived economic situation and education were related to some dimensions of time perspective. PMID- 27718344 TI - Advances in Cardiac Biological Therapies 2016.

AB - Human adipose-derived stem cells (hADSCs) are a promising source of autologous stem cells for personalized cell-based therapies. Culture expansion of ADSCs provides an attractive opportunity for liver cirrhosis patients. However, safety and stability issues can pose big challenges for personalized autologous stem cell products. In the present study, we addressed whether the commercial production program could provide a consistent product for liver cirrhosis therapy. We collected adipose tissue from three human donors by lipoaspirate and isolated ADSCs, which were expanded in culture to reach 1 * 108 cells (an approximately 1,000-fold expansion) within four passages. We then examined their morphology, chromosome stability, surface markers, and differentiation ability after culture. Next, we explored their therapeutic potential using a rat model of thioacetamide-induced liver cirrhosis. Culture-expanded ADSCs were injected intrahepatically, and their biodistribution was tracked by immunohistochemistry using an antibody against human mitochondria. Finally, we tested for tumor development by subcutaneously injecting a 100-fold dose range of cultured ADSCs into immunocompromised mice. Taken together, we find that culture expansion of autologous ADSCs is a potentially suitable stem cell product for personalized cell-based therapy for patients with liver cirrhosis.

PMID- 27718346 TI - Prevalence of Auditory Processing Disorder in School-Aged Children in the Mid Atlantic Region. AB - BACKGROUND: Although auditory processing disorder (APD) is a widely recognized impairment, its prevalence and demographic characteristics are not precisely known in the pediatric population. PURPOSE: To examine the demographic characteristics of children diagnosed with APD at a tertiary health-care facility and the prevalence of pediatric APD. RESEARCH DESIGN: A cross-sectional study. STUDY SAMPLE: A total of 243 children (149 boys and 94 girls) who were referred to the Nemours Audiology Clinics in the Delaware Valley for an APD evaluation. The mean ages were 9.8 yr for boys and 9.7 yr for girls. Out of 243 children referred for an APD evaluation, 94 children exhibited one or more auditory processing deficits in the areas of auditory closure, auditory figure ground, binaural integration, binaural separation, and temporal processing. DATA COLLECTION AND ANALYSIS: Demographic and audiological data, clinical history (parental reports on prenatal and postnatal information, birth weight and height, medical and developmental history, otologic/audiological history, education information, behavioral characteristics), and results of the APD test battery were retrospectively obtained from the electronic medical records of each participant. The prevalence of APD was estimated using the total number of students enrolled in the same school attended by each participant in the 2011 academic year as cohort. RESULTS: The prevalence of APD was 1.94 per 1,000 children in this study. We found that prevalence of APD among the children who attended private schools was more than two times higher than the children who attended public schools. The results also revealed that the majority of children referred to the clinics were Caucasian (85.6%), whereas minority groups were underrepresented for this geographical area with only 3.7% of Hispanic or Latino children and 5.8% of Black or African American children. CONCLUSIONS: The estimated prevalence of APD in the current study was lower than the previously published estimates. The difference might be due to the diagnosis criteria of APD among studies as well as the use of school enrollment number as the referenced population to estimate prevalence in our study. We also found a significant difference in APD prevalence depending on the school types. The findings of higher prevalence rates among the children attending private schools and higher proportion of Caucasians children referred for APD evaluation suggest that more children among those in public schools and in the Hispanic and African American groups should have been referred for an APD evaluation. Hence, the current estimate is likely an underestimate of the actual APD prevalence. The low percentage of Hispanic or African American children referred to the clinic for APD evaluations may be related to the socioeconomic status and linguistic differences among the concerned families. The results of this study raise the importance of adapting the APD test battery for children with a different linguistic background as well as increasing awareness of available clinical resources to all families in our area. PMID- 27718347 TI - Behavioral Measures of Temporal Processing and Speech Perception in Cochlear Implant Users. AB - BACKGROUND: Although most cochlear implant (CI) users achieve improvements in speech perception, there is still a wide variability in speech perception outcomes. There is a growing body of literature that supports the relationship between individual differences in temporal processing and speech perception performance in CI users. Previous psychophysical studies have emphasized the importance of temporal acuity for overall speech perception performance. Measurement of gap detection thresholds (GDTs) is the most common measure currently used to assess temporal resolution. However, most GDT studies completed with CI participants used direct electrical stimulation not acoustic stimulation and they used psychoacoustic research paradigms that are not easy to administer clinically. Therefore, it is necessary to determine if the variance in GDTs assessed with clinical measures of temporal processing such as the Randomized Gap Detection Test (RGDT) can be used to explain the variability in speech perception performance. PURPOSE: The primary goal of this study was to investigate the relationship between temporal processing and speech perception performance in CI users. RESEARCH DESIGN: A correlational study investigating the relationship between behavioral GDTs (assessed with the RGDT or the Expanded Randomized Gap Detection Test) and commonly used speech perception measures (assessed with the Speech Recognition Test [SRT], Central Institute for the Deaf W-22 Word Recognition Test [W-22], Consonant-Nucleus-Consonant Test [CNC], Arizona Biomedical Sentence Recognition Test [AzBio], Bamford-Kowal-Bench Speech-in-Noise Test [BKB-SIN]). STUDY SAMPLE: Twelve postlingually deafened adult CI users (24 83 yr) and ten normal-hearing (NH; 22-30 yr) adults participated in the study. DATA COLLECTION AND ANALYSIS: The data were collected in a sound-attenuated test booth. After measuring pure-tone thresholds, GDTs and speech perception performance were measured. The difference in performance between-participant groups on the aforementioned tests, as well as the correlation between GDTs and speech perception performance was examined. The correlations between participants' biologic factors, performance on the RGDT and speech perception measures were also explored. RESULTS: Although some CI participants performed as well as the NH listeners, the majority of the CI participants displayed temporal processing impairments (GDTs > 20 msec) and poorer speech perception performance than NH participants. A statistically significant difference was found between the NH and CI test groups in GDTs and some speech tests (SRT, W-22, and BKB-SIN). For the CI group, there were significant correlations between GDTs and some measures of speech perception (CNC Phoneme, AzBio, BKB-SIN); however, no significant correlations were found between biographic factors and GDTs or speech perception performance. CONCLUSIONS: Results support the theory that the variability in temporal acuity in CI users contributes to the variability in speech performance. Results also indicate that it is reasonable to use the clinically available RGDT to identify CI users with temporal processing impairments for further appropriate rehabilitation. PMID- 27718348 TI - Brain Positron Emission Tomography-Computed Tomography Gender Differences in Tinnitus Patients. AB - BACKGROUND: Increased metabolism in the left auditory cortex has been reported in tinnitus patients. However, gender difference has not been addressed. PURPOSE: To assess the differences in Positron emission tomography-computed tomography (PET CT) results between the genders in tinnitus patients. RESEARCH DESIGN: Retrospective cohort. STUDY SAMPLE: Included were patients referred to our clinic between January 2011 and August 2013 who complained of tinnitus and underwent fluorodeoxyglucose (FDG)-PET to assess brain metabolism. DATA ANALYSIS: Univariate and multivariate nominal logistic regressions were used to evaluate the association between upper temporal gyrus (UTG; right and left) and gender. RESULTS: Included were 140 patients (87 males) with an average age of 52.5 yr (median = 53.1). Bilateral tinnitus was found in 85 patients (60.7%), left sided in 30 (21.4%), and right sided in 21(15%). Increased uptake in the UTG was found in 60% of the patients on either side. Males had a statistically significant increased uptake in the UTG in those with unilateral tinnitus and in the entire population. CONCLUSIONS: We present the largest study reported so far on tinnitus patients who have undergone FDG-PET-CT. We found a statistically significant difference between the genders in FDG uptake by the UTG. Further investigations should be undertaken to reveal the etiologies for these differences and to assess different therapeutic protocols according to gender. PMID- 27718349 TI - Validation of a Mobile Device for Acoustic Coordinated Reset Neuromodulation Tinnitus Therapy. AB - BACKGROUND: Sound-based tinnitus intervention stimuli include broad-band noise signals with subjectively adjusted bandwidths used as maskers delivered by commercial devices or hearing aids, environmental sounds broadly described and delivered by both consumer devices and hearing aids, music recordings specifically modified and delivered in a variety of different ways, and other stimuli. Acoustic coordinated reset neuromodulation therapy for tinnitus reduction has unique and more stringent requirements compared to all other sound based tinnitus interventions. These include precise characterization of tinnitus pitch and loudness, and effective provision of patient-controlled daily therapy signals at defined frequencies, levels, and durations outside of the clinic. PURPOSE: The purpose of this study was to evaluate an approach to accommodate these requirements including evaluation of a mobile device, validation of an automated tinnitus pitch-matching algorithm and assessment of a patient's ability to control stimuli and collect repeated outcome measures. RESEARCH DESIGN: The experimental design involved direct laboratory measurements of the sound delivery capabilities of a mobile device, comparison of an automated, adaptive pitch matching method to a traditional manual method and measures of a patient's ability to understand and manipulate a mobile device graphic user interface to both deliver the therapy signals and collect the outcome measures. STUDY SAMPLE: This study consisted of 5 samples of a common mobile device for the laboratory measures and a total of 30 adult participants: 15 randomly selected normal hearing participants with simulated tinnitus for validation of a tinnitus pitch matching algorithm and 15 sequentially selected patients already undergoing tinnitus therapy for evaluation of patient usability. INTERVENTION: No tinnitus intervention(s) were specifically studied as a component of this study. DATA COLLECTION AND ANALYSIS: Data collection involved laboratory measures of mobile devices, comparison of manual and automated adaptive tinnitus pitch-matching psychoacoustic procedures in the same participant analyzed for absolute differences (t test), variance differences (f test), and range comparisons, and assessment of patient usability including questionnaire measures and logs of patient observations. RESULTS: Mobile devices are able to reliably and accurately deliver the acoustic therapy signals. There was no difference in mean pitch matches (t test, p > 0.05) between an automated adaptive method compared to a traditional manual pitch-matching method. However, the variability of the automated pitch-matching method was much less (f test, p < 0.05) with twice as many matches within the predefined error range (+/-5%) compared to the manual pitch-matching method (80% versus 40%). After a short initial training, all participants were able to use the mobile device effectively and to perform the required tasks without further professional assistance. PMID- 27718350 TI - Smartphone-Based System for Learning and Inferring Hearing Aid Settings. AB - BACKGROUND: Previous research has shown that hearing aid wearers can successfully self-train their instruments' gain-frequency response and compression parameters in everyday situations. Combining hearing aids with a smartphone introduces additional computing power, memory, and a graphical user interface that may enable greater setting personalization. To explore the benefits of self-training with a smartphone-based hearing system, a parameter space was chosen with four possible combinations of microphone mode (omnidirectional and directional) and noise reduction state (active and off). The baseline for comparison was the "untrained system," that is, the manufacturer's algorithm for automatically selecting microphone mode and noise reduction state based on acoustic environment. The "trained system" first learned each individual's preferences, self-entered via a smartphone in real-world situations, to build a trained model. The system then predicted the optimal setting (among available choices) using an inference engine, which considered the trained model and current context (e.g., sound environment, location, and time). PURPOSE: To develop a smartphone-based prototype hearing system that can be trained to learn preferred user settings. Determine whether user study participants showed a preference for trained over untrained system settings. RESEARCH DESIGN: An experimental within-participants study. Participants used a prototype hearing system-comprising two hearing aids, Android smartphone, and body-worn gateway device-for ~6 weeks. STUDY SAMPLE: Sixteen adults with mild-to-moderate sensorineural hearing loss (HL) (ten males, six females; mean age = 55.5 yr). Fifteen had >=6 mo of experience wearing hearing aids, and 14 had previous experience using smartphones. INTERVENTION: Participants were fitted and instructed to perform daily comparisons of settings ("listening evaluations") through a smartphone-based software application called Hearing Aid Learning and Inference Controller (HALIC). In the four-week-long training phase, HALIC recorded individual listening preferences along with sensor data from the smartphone-including environmental sound classification, sound level, and location-to build trained models. In the subsequent two-week-long validation phase, participants performed blinded listening evaluations comparing settings predicted by the trained system ("trained settings") to those suggested by the hearing aids' untrained system ("untrained settings"). DATA COLLECTION AND ANALYSIS: We analyzed data collected on the smartphone and hearing aids during the study. We also obtained audiometric and demographic information. RESULTS: Overall, the 15 participants with valid data significantly preferred trained settings to untrained settings (paired-samples t test). Seven participants had a significant preference for trained settings, while one had a significant preference for untrained settings (binomial test). The remaining seven participants had nonsignificant preferences. Pooling data across participants, the proportion of times that each setting was chosen in a given environmental sound class was on average very similar. However, breaking down the data by participant revealed strong and idiosyncratic individual preferences. Fourteen participants reported positive feelings of clarity, competence, and mastery when training via HALIC. CONCLUSIONS: The obtained data, as well as subjective participant feedback, indicate that smartphones could become viable tools to train hearing aids. Individuals who are tech savvy and have milder HL seem well suited to take advantages of the benefits offered by training with a smartphone. PMID- 27718351 TI - An Estimation of the Whole-of-Life Noise Exposure of Adolescent and Young Adult Australians with Hearing Impairment. AB - BACKGROUND: Since amplified music gained widespread popularity, there has been community concern that leisure-noise exposure may cause hearing loss in adolescents and young adults who would otherwise be free from hearing impairment. Repeated exposure to personal stereo players and music events (e.g., nightclubbing, rock concerts, and music festivals) are of particular concern. The same attention has not been paid to leisure-noise exposure risks for young people with hearing impairment (either present from birth or acquired before adulthood). This article reports on the analysis of a subset of data (leisure participation measures) collected during a large, two-phase study of the hearing health, attitudes, and behaviors of 11- to 35-yr-old Australians conducted by the National Acoustic Laboratories (n = 1,667 hearing threshold level datasets analyzed). The overall aim of the two-phase study was to determine whether a relationship between leisure-noise exposure and hearing loss exists. PURPOSE: In the current study, the leisure activity profiles and accumulated ("whole-of life") noise exposures of young people with (1) hearing impairment and (2) with normal hearing were compared. RESEARCH DESIGN: Cross-sectional cohort study. STUDY SAMPLE: Hearing impaired (HI) group, n = 125; normal (nonimpaired) hearing (NH) group, n = 296, analyzed in two age-based subsets: adolescents (13- to 17-yr olds) and young adults (18- to 24-yr-olds). DATA COLLECTION AND ANALYSIS: Participant survey. The chi2 test was used to identify systematic differences between the leisure profiles and exposure estimates of the HI and NH groups. Whole-of-life noise exposure was estimated by adapting techniques described in ISO 1999. RESULTS: For adolescents, leisure profiles were similar for the two groups and few individuals exceeded the stated risk criterion. For young adults, participation was significantly lower for the HI group for 7 out of 18 leisure activities surveyed. Activity diversity and whole-of-life exposure were also significantly lower for the HI group young adults. A substantial number of individuals in both groups reported participation in leisure activities known to involve high noise levels (HI < NH). The individual whole-of-life exposures for the HI and NH participants were estimated and group median exposures were calculated. The median exposure for HI group young adults was significantly lower than that for the NH group (710 versus 1,615 Pa2 h [Pascal squared hours]). CONCLUSIONS: The number of young adults with estimated exposure above the chosen noise-risk criterion in the NH group is concerning. With respect to the goals of hearing loss prevention initiatives, the more conservative social behavior (e.g., less nightclubbing) observed among HI group young adults may be regarded as a positive finding, but it could also signify relative social disadvantage for some young adults with hearing impairment.

PMID- 27718352 TI - Utility of the Frequency Tuning Measure of oVEMP in Differentiating Meniere's Disease from BPPV. AB - BACKGROUND: Utility of frequency tuning of ocular vestibular evoked myogenic potential (oVEMP) for evaluation of utricular function in individuals with Meniere's disease is a recent development. However, there is dearth of studies regarding its utility in differential diagnosis of Meniere's disease from other vestibular pathologies. PURPOSE: The present study aimed at investigating the feasibility of frequency tuning of oVEMP in discriminating Meniere's disease from benign paroxysmal positional vertigo (BPPV). RESEARCH DESIGN: Static group comparison. STUDY SAMPLE: oVEMPs were acquired from 36 individuals, each with unilateral Meniere's disease and unilateral BPPV. Thirty-six age- and gender matched healthy individuals formed comparison group for each of the two clinical groups. INTERVENTION: Contralateral oVEMPs were recorded from both ears of all the participants. DATA COLLECTION AND ANALYSES: The responses pertaining to octave and mid-octave frequencies from 250 to 4000 Hz, one frequency presented at a time, were recorded from infra-orbital electrodes (noninverting placed 1 cm below the lower eyelid and inverting 2 cm below the inverting on the cheek) with forehead as ground. Starting intensity was 125 dB peSPL with subsequent reductions in 10-dB steps to arrive at threshold. The stimuli were delivered to the ear at a rate of 5.1 Hz. The frequency corresponding to the largest peak-to peak amplitude, best threshold, and/or largest peak-to-peak amplitude at thresholds was considered as the tuning frequency. Proportions of ears with frequency tuning at a particular frequency were compared between the groups. RESULTS: The frequency tuning at 1000 Hz was found to exist in a significantly higher proportion of affected ears with Meniere's disease than the comparison group as well as ears with BPPV (p < 0.05). Using a criterion point of frequency tuning at 875 Hz, the sensitivity and specificity for identifying Meniere's disease was found to be 68% and 100%, respectively. CONCLUSION: The shift in frequency tuning is an efficient parameter for not only discriminating Meniere's disease from healthy individuals but also distinguishing it from BPPV. Therefore, frequency tuning is recommended as a test parameter of oVEMP for identification of Meniere's disease. PMID- 27718354 TI - Response to Johnson. PMID- 27718358 TI - E. coli metabolic engineering for gram scale production of a plant-based anti inflammatory agent. AB - In this report, the heterologous production of salicylate (SA) is the basis for metabolic extension to salicylate 2-O-beta-d-glucoside (SAG), a natural product implicated in plant-based defense mechanisms. Production was optimized through a combination of metabolic engineering, gene expression variation, and co-culture design. When combined, SA and SAG production titers reached ~0.9g/L and ~2.5g/L, respectively. The SAG compound was then tested for anti-inflammatory properties relative to SA and acetylsalicylate (aspirin). Results indicate comparable activity between SAG and aspirin in reducing nitric oxide (NO) and reactive oxygen species (ROS) from macrophage cells while no discernable negative effects on cellular viability were observed. PMID- 27718357 TI - Ankyrin-B is a PI3P effector that promotes polarized alpha5beta1-integrin recycling via recruiting RabGAP1L to early endosomes. AB - Endosomal membrane trafficking requires coordination between phosphoinositide lipids, Rab GTPases, and microtubule-based motors to dynamically determine endosome identity and promote long-range organelle transport. Here we report that ankyrin-B (AnkB), through integrating all three systems, functions as a critical node in the protein circuitry underlying polarized recycling of alpha5beta1 integrin in mouse embryonic fibroblasts, which enables persistent fibroblast migration along fibronectin gradients. AnkB associates with phosphatidylinositol 3-phosphate (PI3P)-positive organelles in fibroblasts and binds dynactin to promote their long-range motility. We demonstrate that AnkB binds to Rab GTPase Activating Protein 1-Like (RabGAP1L) and recruits it to PI3P-positive organelles, where RabGAP1L inactivates Rab22A, and promotes polarized trafficking to the leading edge of migrating fibroblasts. We further determine that alpha5beta1 integrin depends on an AnkB/RabGAP1L complex for polarized recycling. Our results reveal AnkB as an unexpected key element in coordinating polarized transport of alpha5beta1-integrin and likely of other specialized endocytic cargos. PMID- 27718356 TI - A widely employed germ cell marker is an ancient disordered protein with reproductive functions in diverse eukaryotes. AB - The advent of sexual reproduction and the evolution of a dedicated germline in multicellular organisms are critical landmarks in eukaryotic evolution. We report an ancient family of GCNA (germ cell nuclear antigen) proteins that arose in the earliest eukaryotes, and feature a rapidly evolving intrinsically disordered region (IDR). Phylogenetic analysis reveals that GCNA proteins emerged before the major eukaryotic lineages diverged; GCNA predates the origin of a dedicated germline by a billion years. Gcna gene expression is enriched in reproductive cells across eukarya - either just prior to or during meiosis in single-celled eukaryotes, and in stem cells and germ cells of diverse multicellular animals. Studies of Gcna-mutant C. elegans and mice indicate that GCNA has functioned in reproduction for at least 600 million years. Homology to IDR-containing proteins implicated in DNA damage repair suggests that GCNA proteins may protect the genomic integrity of cells carrying a heritable genome. PMID- 27718359 TI - Projections from the lowest lumbar and sacral-caudal segments to the cerebellar cortex in the rat: An anterograde tracing study. AB - The crossed spinocerebellar tracts originate from neurons in the basolateral part of lamina V, the sacral nuclei of Stilling and the ventrolateral part of the ventral horn of the L6 to caudal segments. The present study examined their projection areas in the cerebellar cortex by using anterograde labeling of mossy fiber terminals with biotinylated dextran in the rat. Labeled terminals were distributed bilaterally in lobules I-V of the anterior lobe. They were most abundant in the apical parts of the lateral vermis and the intermediate region of lobules Ib and IIa, and the rostral side of lobule IIb. The number of labeled terminals in lobules Ib-IIb accounted for 56% and 81%, respectively, of the total 9783 and 7045 labeled terminals. The number of labeled terminals decreased in lobules III to V. In the posterior lobe labeled terminals were distributed exclusively to lobules VIIIa and VIIIb and copula pyramidis. The present study demonstrates that spinocerebellar neurons of the sacral-caudal segments project primarily to the lateral part of lobules I and II, and less densely to lobules III-V and VIII, and copula pyramidis. The projection pattern was essentially similar to that observed in the cat. PMID- 27718360 TI - Does Mandibular Distraction Vector Influence Airway Volumes and Outcome? AB - PURPOSE: The goal of mandibular distraction in the Pierre-Robin sequence is to maximally expand the oropharyngeal airway. It has been hypothesized that a steep oblique distraction vector might allow greater airway enlargement compared with horizontal distraction. This study compared vector orientation in relation to airway volume and overall clinical outcome. MATERIALS AND METHODS: Micrognathic infants who underwent mandibular distraction with sufficient computed tomographic data were retrospectively reviewed. Demographic, diagnostic, perioperative, and distraction data were recorded. Groups were separated based on distraction vector (group 1, horizontal; group 2, oblique). Airway and mandibular volumes were measured using Mimics (Materialise, Leuven, Belgium). Morphologic and outcomes data were analyzed. Statistics involved 2-tailed t test, Pearson correlation, and analysis of covariance (ANCOVA). RESULTS: Mean age at distraction was 40 days, with devices maintained for 82 days on average. Fifty percent of patients were girls and 65% had cleft palate. Forty computed tomograms were analyzed. Airway (1,234 vs 3,501 mm3; P < .01) and mandibular (5,457 vs 11,827 mm3; P < .01) volumes, minimal airway area (12.5 vs 63.7 mm2; P < .01), and posterior airway space distance (2.3 vs 9.8 mm; P = .04) were significantly increased after distraction. Patients also had clinically improved sleep studies after distraction (apnea hypopnea index, 51.3 vs 5.5; P < .01). Vector analysis showed an average of 5.3 degrees and 14.0 degrees in groups 1 and 2, respectively (n = 10 each). Intergroup analysis showed a trend toward increased airway volume in horizontal vectors (548 vs 255% of preoperative volume; P = .058), with slightly longer distraction length (20.3 vs 16.6 mm; P = .17). However, ANCOVA regression analysis showed no difference in the relation between vector and length. Other morphologic data and sleep study outcomes (apnea hypopnea index, 7.0 vs 3.9; P = .09) also were not statistically different between groups. Longer lengths of distraction correlated with narrower anterior mandibular angle and longer mandibular body length. CONCLUSIONS: Substantial airway enlargement occurs after mandibular distraction. Final airway volumes were similar between groups regardless of vector, which was confirmed by multivariate ANCOVA regression. The 2 methods achieved airway stabilization, with clinical outcomes similar between the 2 groups. PMID- 27718361 TI - The regulation of human globin promoters by CCAAT box elements and the recruitment of NF-Y. AB - CCAAT boxes are motifs found within the proximal promoter of many genes, including the human globin genes. The highly conserved nature of CCAAT box motifs within the promoter region of both alpha-like and beta-like globin genes emphasises the functional importance of the CCAAT sequence in globin gene regulation. Mutations within the beta-globin CCAAT box result in beta thalassaemia, while mutations within the distal gamma-globin CCAAT box cause the Hereditary Persistence of Foetal Haemoglobin, a benign condition which results in continued gamma-globin expression during adult life. Understanding the transcriptional regulation of the globin genes is of particular interest, as reactivating the foetal gamma-globin gene alleviates the symptoms of beta thalassaemia and sickle cell anaemia. NF-Y is considered to be the primary activating transcription factor which binds to globin CCAAT box motifs. Here we review recruitment of NF-Y to globin CCAAT boxes and the role NF-Y plays in regulating globin gene expression.

AB - Therapeutic protein kinase inhibitors are designed on the basis of kinase structures. Here, we define intrinsically disordered regions (IDRs) in structurally hybrid kinases. We reveal that 65% of kinases have an IDR adjacent to their kinase domain (KD). These IDRs are evolutionarily more conserved than IDRs distant to KDs. Strikingly, 36 kinases have adjacent IDRs extending into their KDs, defining a unique structural and functional subset of the kinome. Functional network analysis of this subset of the kinome uncovered FAK1 as topologically the most connected hub kinase. We identify that KD-flanking IDR of FAK1 is more conserved and undergoes more post-translational modifications than other IDRs. It preferentially interacts with proteins regulating scaffolding and kinase activity, which contribute to cytoskeletal remodeling. In summary, spatially and evolutionarily conserved IDRs in kinases may influence their functions, which can be exploited for targeted therapies in diseases including those that involve aberrant cytoskeletal remodeling.

AB - OBJECTIVE: To describe the breastfeeding experiences of mothers with preterm and low-birth-weight infants in a neonatal unit in Tanzania. DESIGN: A qualitative research design. SETTING: A neonatal unit at a referral hospital in rural Tanzania. PARTICIPANTS: Convenience sample of 10 new mothers with preterm infants. Additionally, to triangulate the data, five nurses affiliated with the neonatal unit were interviewed. METHODS: A semistructured interview guide was used for data collection. All interviews were audiotaped and transcribed verbatim. Data were analyzed with inductive qualitative content analysis. RESULTS: One main category, The mother has to adapt to the new situation to make breastfeeding natural, and three generic categories, The challenges of breastfeeding a premature infant, Enhancing the feeding situation, and The need for support, were used to describe breastfeeding challenges. Challenges consisted of the perception that the infant was different than healthy infants and the infant's and mother's health problems and needs. To improve the feeding situation, mothers learned how to feed their infants using timing strategies. Confidence and security were achieved with support from family and friends, the other mothers, and the health care staff. CONCLUSION: Mothers perceived breastfeeding as natural but needed support to overcome the challenges of breastfeeding preterm infants. Through support and education they were empowered, adapted to their new situations, and felt confident with breastfeeding. PMID- 27718364 TI - Uptake and metabolism of fluorescent steroids by mycobacterial cells. AB - Fluorescent steroids BODIPY-cholesterol (BPCh) and 7-nitrobenzoxadiazole-4-amino (NBD)-labeled 22-NBD-chelesterol (22NC) as well as synthesized 20-(NBD)-pregn-5 en-3beta-ol (20NP) were found to undergo bioconversions by Mycobacterium tuberculosis H37Rv and M. smegmatis mc2 155. The major fluorescent products were determined to be 4-en-3-one derivatives of the compounds. Degradation of NBD fluorophore was also detected in the cases of 22NC and 20NP, but neither NBD degradation nor steroidal part modification were observed for the synthesized 3 (NBD)-cholestane. Mycobacterial 3beta-hydroxysteroid dehydrogenases were concluded to be responsible for the formation of the 4-en-3-one derivatives. All the compounds tested were found to cause staining both membrane lipids and cytosolic lipid droplets when incubated with mycobacteria in different manner, demonstrating ability of the steroids to reside in the compartments. The findings reveal a potential of the compounds for monitoring of steroid interactions with mycobacteria and provide information for design of new probes for this purpose. PMID- 27718366 TI - Expert Panel to Track Nurses' Effect on Maternal Morbidity and Mortality. AB - Rates of maternal morbidity and mortality in the United States have increased since 1990. Registered nurses are members of the health care work force who provide essential care to women during pregnancy, during birth, and after birth. Tools are needed to more effectively measure and track the effect of nursing care on maternal health outcomes. The Association of Women's Health, Obstetric and Neonatal Nurses and the Association of Maternal & Child Health Programs co convened an expert panel to develop a set of tools for use by public health and clinical leaders to support this effort. PMID- 27718367 TI - A Concept Analysis on the Use of Yakson in the NICU. AB - In the NICU context, Yakson is defined as a mother's gentle, nurturing, and soothing touch that is meant to comfort her newborn and results in the newborn's physically relaxed and emotionally stable condition, the mother's satisfaction and confidence, and stronger mother-infant interaction and attachment. Although this concept analysis is based on Korean culture, the understanding of Yakson can help nurses promote this feasible practice to enhance mother-infant interaction and attachment in the NICU. PMID- 27718368 TI - Vicarious Posttraumatic Growth in Labor and Delivery Nurses. AB - OBJECTIVE: To investigate vicarious posttraumatic growth in labor and delivery nurses who cared for women during traumatic births. DESIGN: A convergent parallel mixed-methods design was used. PARTICIPANTS: The sample consisted of 467 labor and delivery nurses who completed the quantitative portion and 295 (63%) who completed the qualitative portion of this mixed-methods study via the Internet. METHODS: The Association of Women's Health, Obstetric and Neonatal Nurses sent out e-mails to members who were labor and delivery nurses with a link to the electronic survey. Labor and delivery nurses completed the Posttraumatic Growth Inventory and the Core Beliefs Inventory in the quantitative portion. For the qualitative portion, the nurses were asked to describe their experiences of any positive changes in their beliefs or life as a result of their care for women during traumatic births. RESULTS: Labor and delivery nurses who cared for women during traumatic births reported a moderate amount of vicarious posttraumatic growth as indicated by their Posttraumatic Growth Inventory scores. Appreciation of Life was the dimension of the Posttraumatic Growth Inventory that reflected the highest growth, followed by Relating to Others, Personal Strength, Spiritual Change, and New Possibilities. In the qualitative findings, Relating to Others was also the dimension of posttraumatic growth most frequently described. CONCLUSION: We compared our results with those of previous studies in which researchers assessed vicarious posttraumatic growth in clinicians, and we found that labor and delivery nurses who cared for women during traumatic births experienced growth levels that were scored between the lowest and highest reported levels of therapists and social workers. Nurses need to be aware of the potential to experience this growth despite the significant stress and unpredictability of the labor and delivery environment, which could decrease burnout and improve retention rates.

AB - Cholesterol crystalline domains characterize atherosclerotic membranes, altering vascular signaling and function. Omega-3 fatty acids reduce membrane lipid peroxidation and subsequent cholesterol domain formation. We evaluated non peroxidation-mediated effects of eicosapentaenoic acid (EPA), other TG-lowering agents, docosahexaenoic acid (DHA), and other long-chain fatty acids on membrane fluidity, bilayer width, and cholesterol domain formation in model membranes. In membranes prepared at 1.5:1 cholesterol-to-phospholipid (C/P) mole ratio (creating pre-existing domains), EPA, glycyrrhizin, arachidonic acid, and alpha linolenic acid promoted the greatest reductions in cholesterol domains (by 65.5%, 54.9%, 46.8%, and 45.2%, respectively) compared to controls; other treatments had modest effects. EPA effects on cholesterol domain formation were dose-dependent. In membranes with 1:1 C/P (predisposing domain formation), DHA, but not EPA, dose dependently increased membrane fluidity. DHA also induced cholesterol domain formation without affecting temperature-induced changes in-bilayer unit cell periodicity relative to controls (d-space; 57A-55A over 15-30 degrees C). Together, these data suggest simultaneous formation of distinct cholesterol-rich ordered domains and cholesterol-poor disordered domains in the presence of DHA. By contrast, EPA had no effect on cholesterol domain formation and produced larger d-space values relative to controls (60A-57A; p<0.05) over the same temperature range, suggesting a more uniform maintenance of lipid dynamics despite the presence of cholesterol. These data indicate that EPA and DHA had different effects on membrane bilayer width, membrane fluidity, and cholesterol crystalline domain formation; suggesting omega-3 fatty acids with differing chain length or unsaturation may differentially influence membrane lipid dynamics and structural organization as a result of distinct phospholipid/sterol interactions. PMID- 27718369 TI - Change in cytokine levels is not associated with rapid antidepressant response to ketamine in treatment-resistant depression. AB - Several pro-inflammatory cytokines have been implicated in depression and in antidepressant response. This exploratory analysis assessed: 1) the extent to which baseline cytokine levels predicted positive antidepressant response to ketamine; 2) whether ketamine responders experienced acute changes in cytokine levels not observed in non-responders; and 3) whether ketamine lowered levels of pro-inflammatory cytokines, analogous to the impact of other antidepressants. Data from double-blind, placebo-controlled studies of patients with major depressive disorder (MDD) or bipolar disorder (BD) who received a single infusion of sub-anesthetic dose ketamine were used (N = 80). Plasma levels of the eight cytokines were measured at baseline and at 230 min, 1 day, and 3 days post ketamine. A significant positive correlation was observed between sTNFR1 and severity of depression at baseline. Cytokine changes did not correlate with changes in mood nor predict mood changes associated with ketamine administration. Ketamine significantly increased IL-6 levels and significantly decreased sTNFR1 levels. IL-6 and TNF-alpha levels were also significantly higher-and sTNFR1 levels were significantly lower-in BD compared to MDD subjects. The functional significance of this difference is unknown. Changes in cytokine levels post ketamine were not related to antidepressant response, suggesting they are not a primary mechanism involved in ketamine's acute antidepressant effects. Taken together, the results suggest that further study of cytokine levels is warranted to assess their potential role as a surrogate outcome in the rapid antidepressant response paradigm. PMID- 27718371 TI - Has the great recession and its aftermath reduced traffic fatalities? AB - An analysis of state-level data from 1984 to 2014 provides evidence on the relationship between economic recessions and US traffic fatalities. While there are large reductions associated with decreases in household median income, other policy variables tend to have additional and in some cases, larger effects. An increase in the inequality of the income distribution, measured by the Gini index, has reduced traffic fatalities. Graduated licensing policies, cell phone laws, and motorcycle helmet requirements are all associated with reductions in fatalities. Other factors include a proxy for medical technology, and access to emergency medical services (based on the percent of vehicle miles traveled in rural areas); reductions in the latter accounted for a substantial reduction in fatalities and is likely another indicator of reduced economic activity. Changes in the road network, mainly increases in the percent of collector roads has increased fatalities. Population growth is associated with increased traffic fatalities and changes in age cohorts has a small negative effect. Overall, results suggest that there has been a beneficial impact on traffic fatalities from reduced economic activity, but various policies adopted by the states have also reduced traffic fatalities. PMID- 27718373 TI - The association between serum cathepsin L and mortality in older adults. AB - BACKGROUND AND AIMS: Research suggests that the protease cathepsin L is causally involved in atherosclerosis. However, data on cathepsin L as a risk marker are lacking. Therefore, we investigated associations between circulating cathepsin L and cardiovascular mortality. METHODS: Two independent community-based cohorts were used: Uppsala Longitudinal Study of Adult Men (ULSAM); n = 776; mean age 77 years; baseline 1997-2001; 185 cardiovascular deaths during 9.7 years follow-up, and Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS); n = 993; 50% women; mean age 70 years; baseline 2001-2004; 42 cardiovascular deaths during 10.0 years follow-up. RESULTS: Higher serum cathepsin L was associated with an increased risk for cardiovascular mortality in age- and sex-adjusted models in both cohorts (ULSAM: hazard ratio (HR) for 1-standard deviation (SD) increase, 1.17 [95% CI, 1.01-1.34], p = 0.032 PIVUS: HR 1.35 [95% CI, 1.07-1.72], p = 0.013). When merging the cohorts, these associations were independent of inflammatory markers and cardiovascular risk factors, but non-significant adjusting for kidney function. Individuals with a combination of elevated cathepsin L and increased inflammation, kidney dysfunction, or prevalent cardiovascular disease had a markedly increased risk, while no increased risk was associated with elevated cathepsin L, in the absence of these disease states. CONCLUSIONS: An association between higher serum cathepsin L and increased risk of cardiovascular mortality was found in two independent cohorts. Impaired kidney function appears to be an important moderator or mediator of these associations. Further studies are needed to delineate the underlying mechanisms and to evaluate whether the measurement of cathepsin L might have clinical utility. PMID- 27718372 TI - Carotid plaque fissure: An underestimated source of intraplaque hemorrhage. AB - BACKGROUND AND AIMS: Plaque fissuring, a phenomenon morphologically distinct from the classical rupture of a thinned fibrous cap, has not been well characterized in carotid atherosclerosis. The aim of this study was to establish the prevalence of plaque fissures in advanced carotid plaques with an otherwise intact luminal surface, and to determine whether they might be a source of intraplaque hemorrhage (IPH). METHODS: We evaluated 244 surgically intact, 'en bloc' embedded, serially sectioned carotid endarterectomy specimens and included only those plaques with a grossly intact luminal surface. RESULTS: Among the 67 plaques with grossly intact luminal surface, cap fissure was present in 39 (58%) plaques. A total of 60 individual fissures were present, and longitudinally mean fissure length was 1.3 mm. Most fissures were found distal to the bifurcation (63%), proximal to the stenosis (88%), and in the posterior (opposite the flow divider) or lateral quadrants (80%). 36% of the fissures remained in the superficial third of the plaque. 52% extended from the lumen surface to the middle third of the plaque and 12% reached the outer third of the plaque on cross section. Fissures often occurred between two tissue planes and were connected to IPH (fresh: 63%; any type: 92%) and calcifications (43%). No correlation was found with patient characteristics such as symptom status, carotid stenosis, hypertension, diabetes, smoking and medications (statins or antiplatelet agents). CONCLUSIONS: Plaque fissures are common in advanced carotid plaques with an otherwise grossly intact luminal surface and are associated with fresh intraplaque hemorrhage. As they occur on the interface between plaque components with different mechanical properties, further biomechanical studies are needed to unravel the underlying failure mechanisms. PMID- 27718375 TI - Screen for genes involved in radiation survival of Escherichia coli and construction of a reference database. AB - A set of 3907 single-gene knockout (Keio collection) strains of Escherichia coli K-12 was examined for strains with increased susceptibility to killing by X- or UV-radiation. After screening with a high-throughput resazurin-based assay and determining radiation survival with triplicate clonogenic assays, we identified 76 strains (and associated deleted genes) showing statistically-significant increased radiation sensitivity compared to a control strain. To determine gene novelty, we constructed a reference database comprised of genes found in nine similar studies including ours. This database contains 455 genes comprised of 103 common genes (found 2-7 times), and 352 uncommon genes (found once). Our 76 genes includes 43 common genes and 33 uncommon (potentially novel) genes, i.e., appY, atoS, betB, bglJ, clpP, cpxA, cysB, cysE, ddlA, dgkA, dppF, dusB, elfG, eutK, fadD, glnA, groL, guaB, intF, prpR, queA, rplY, seqA, sufC,yadG, yagJ, yahD, yahO, ybaK, ybfA, yfaL, yhjV, and yiaL. Of our 33 uncommon gene mutants, 4 (12%) were sensitive only to UV-radiation, 10 (30%) only to X-radiation, and 19 (58%) to both radiations. Our uncommon mutants vs. our common mutants showed more radiation specificity, i.e., 12% vs. 9% (sensitive only to UV-); 30% vs. 16% (X-) and 58% vs. 74% (both radiations). Considering just our radiation-sensitive mutants, the median UV-radiation survival (75Jm-2) for 23 uncommon mutants was 6.84E-3 compared to 1.85E-3 for 36 common mutants (P=0.025). Similarly, the average X-radiation survival for 29 uncommon mutants was 1.08E-2, compared to 6.19E-3 for 39 common mutants (P=0.010). Comparing gene functions using MultiFun terms, uncommon genes tended to show less involvement in DNA repair-relevant categories (information transfer and cell processes), but greater involvement in seven other categories. Our analysis of 455 genes suggests cell survival and DNA repair processes are more complex than previously understood, and may be compromised by deficiencies in other processes. PMID- 27718374 TI - Patient-reported outcomes and visual acuity after 12months of anti-VEGF-treatment for sight-threatening diabetic macular edema in a real world setting. AB - AIMS: To examine objective visual acuity measured with ETDRS, retinal thickness (OCT), patient reported outcome and describe levels of glycated hemoglobin and its association with the effects on visual acuity in patients treated with anti VEGF for visual impairment due to diabetic macular edema (DME) during 12months in a real world setting. METHODS: In this cross-sectional study, 58 patients (29 females and 29 males; mean age, 68years) with type 1 and type 2 diabetes diagnosed with DME were included. Medical data and two questionnaires were collected; an eye-specific (NEI VFQ-25) and a generic health-related quality of life questionnaire (SF-36) were used. RESULTS: The total patient group had significantly improved visual acuity and reduced retinal thickness at 4months and remains at 12months follow up. Thirty patients had significantly improved visual acuity, and 27 patients had no improved visual acuity at 12months. The patients with improved visual acuity had significantly improved scores for NEI VFQ-25 subscales including general health, general vision, near activities, distance activities, and composite score, but no significant changes in scores were found in the group without improvements in visual acuity. CONCLUSIONS: Our study revealed that anti-VEGF treatment improved visual acuity and central retinal thickness as well as patient-reported outcome in real world 12months after treatment start. PMID- 27718376 TI - Helical comb magnetostrictive patch transducers for inspecting spiral welded pipes using flexural guided waves. AB - A wavefront analysis indicates that a flexural wave propagates at a helix angle with respect to the pipe axis. The expression for calculation of the helix angle for each flexural mode is given, and the helix angle dispersion curves for flexural modes are calculated. According to the new understanding of flexural guided waves, a helical comb magnetostrictive patch transducer (HCMPT) is proposed for selectively exciting a single predominant flexural torsional guided wave in a pipe and inspecting spiral welded pipes using flexural waves. A HCMPT contains a pre-magnetized magnetostrictive patch that is helically coupled with the outer surface of a pipe, and a novel compound comb coil that is wrapped around the helical magnetostrictive patch. The proposed wideband HCMPT possesses the direction control ability. A verification experiment indicates that flexural torsional mode T(3,1) at center frequency f=64kHz is effectively actuated by a HCMPT with 13-degree helix angle. Flexural torsional modes T(N,1) with circumferential order N equals 1-5 are selected to inspect a seamless steel pipe, artificial defects are effectively detected by the proposed HCMPT. A 20-degree HCMPT is adopted to inspect a spiral welded pipe, an artificial notch with cross section loss CSL=2.7% is effectively detected by using flexural waves. PMID- 27718377 TI - Dissimilar trend of nonlinearity in ultrasound transducers and systems at resonance and non-resonance frequencies. AB - Several factors can affect performance of an ultrasound system such as quality of excitation signal and ultrasound transducer behaviour. Nonlinearity of piezoelectric ultrasound transducers is a key determinant in designing a proper driving power supply. Although, the nonlinearity of piezoelectric transducer impedance has been discussed in different literatures, the trend of the nonlinearity at different frequencies with respect to excitation voltage variations has not been clearly investigated in practice. In this paper, to demonstrate how the nonlinearity behaves, a sandwich piezoceramic transducer was excited at different frequencies. Different excitation signals were generated using a linear power amplifier and a multilevel converter within a range of 30 200V. Empirical relation was developed to express the resistance of the piezoelectric transducer as a nonlinear function of both excitation voltage and resonance frequency. The impedance measurements revealed that at higher voltage ranges, the piezoelectric transducer can be easily saturated. Also, it was shown that for the developed ultrasound system composed of two transducers (one transmitter and one receiver), the output voltage measured across receiver is a function of a voltage across the resistor in the RLC branches and is related to the resonance frequencies of the ultrasound transducer. PMID- 27718378 TI - Nonlinear imaging (NIM) of flaws in a complex composite stiffened panel using a constructive nonlinear array (CNA) technique. AB - Recently, there has been high interest in the capabilities of nonlinear ultrasound techniques for damage/defect detection as these techniques have been shown to be quite accurate in imaging some particular type of damage. This paper presents a Constructive Nonlinear Array (CNA) method, for the detection and imaging of material defects/damage in a complex composite stiffened panel. CNA requires the construction of an ultrasound array in a similar manner to standard phased arrays systems, which require multiple transmitting and receiving elements. The method constructively phase-match multiple captured signals at a particular position given multiple transmit positions, similar to the total focusing method (TFM) method. Unlike most of the ultrasonic linear techniques, a longer excitation signal was used to achieve a steady-state excitation at each capturing position, so that compressive and tensile stress at defect/crack locations increases the likelihood of the generation of nonlinear elastic waves. Moreover, the technique allows the reduction of instrumentation nonlinear wave generation by relying on signal attenuation to naturally filter these errors. Experimental tests were carried out on a stiffened panel with manufacturing defects. Standard industrial linear ultrasonic test were carried out for comparison. The proposed new method allows to image damages/defects in a reliable and reproducible manner and overcomes some of the main limitations of nonlinear ultrasound techniques. In particular, the effectiveness and robustness of CNA and the advantages over linear ultrasonic were clearly demonstrated allowing a better resolution and imaging of complex and realistic flaws. PMID- 27718379 TI - Negative emotional reactivity moderates the relations between family cohesion and internalizing and externalizing symptoms in adolescence. AB - Lower family cohesion is associated with adolescent internalizing and externalizing problems. However, there are likely individual differences in youth's responses to family processes. For example, adolescents higher in negative emotional reactivity, who often exhibit elevated physiological responsivity to context, may be differentially affected by family cohesion. We explored whether youth's negative emotional reactivity moderated the relation between family cohesion and youth's symptoms and tested whether findings were consistent with the diathesis-stress model or differential susceptibility hypothesis. Participants were 651 adolescents (M = 12.99 +/- .95 years old; 72% male) assessed at two time points (Time 1, ages 12-14; Time 2, age 16) in Pittsburgh, PA. At Time 1, mothers reported on family cohesion and youth reported on their negative emotional reactivity. At Time 2, youth reported on their symptoms. Among youth higher in negative emotional reactivity, lower family cohesion predicted higher symptoms than higher family cohesion, consistent with the diathesis-stress model. PMID- 27718381 TI - Molecular characterization of lake sediment WEON by Fourier transform ion cyclotron resonance mass spectrometry and its environmental implications. AB - The compositional properties of water-extractable organic nitrogen (WEON) affect its behavior in lake ecosystems. This work is the first comprehensive study using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) for the characterization of the molecular composition of WEON in lake sediment. In sediments of Erhai Lake in China, this study found complex WEON species, with N containing compounds in the northern, central, and southern regions contributing 34.47%, 42.44%, and 40.6%, respectively, of total compounds. Additionally, a van Krevelen diagram revealed that lignin components were dominant in sediment WEON structures (68% of the total), suggesting terrestrial sources. Furthermore, this study applied ESI-FT-ICR-MS to the examination of the environmental processes of lake sediment WEON on a molecular level. The results indicated that sediment depth impacted WEON composition and geochemical processes. Compared with other ecosystems, the double bond equivalent (DBE) value was apparently lower in Erhai sediment, indicating the presence of relatively fewer and smaller aromatic compounds. In addition, the presence of a large number of N-containing species and abundant oxidized nitrogen functional compounds that were likely to biodegrade may have further increased the potential releasing risk of WEON from Erhai sediment under certain environmental conditions. PMID- 27718380 TI - The sense of relational entitlement among adolescents toward their parents (SREap) - Testing an adaptation of the SRE. AB - The quality of the adolescent-parent relationship is closely related to the adolescent's sense of entitlement. Study 1 (458 central-Israel adolescents, 69% girls, ages: 11-16) developed the sense of relational entitlement among adolescents toward their parents (SREap, adapted from the original SRE on adults' romantic relationships) and provided initial validity evidence of its three factor structure: exaggerated, restricted and assertive - replicating the SRE's factor structure. Studies 2-5 (1237 adolescents, 56% girls) examined the link between the SREap factors and relevant psychological measures. Exaggerated and restricted SREap factors were associated with attachment insecurities. Restricted and exaggerated entitlement factors were related to higher levels of emotional problems, and lower levels of: wellbeing, positive mood and life satisfaction. Conversely, assertive entitlement was related to higher life satisfaction and self-efficacy and lower levels of emotional problems. The findings also indicate that SREap is not merely a form of narcissism. The implications of SREap are discussed. PMID- 27718382 TI - Determination of recharge fraction of injection water in combined abstraction injection wells using continuous radon monitoring. AB - The recharge fractions of injection water in combined abstraction-injection wells (AIW) were determined using continuous radon monitoring and radon mass balance model. The recharge system consists of three combined abstraction-injection wells, an observation well, a collection tank, an injection tank, and tubing for heating and transferring used groundwater. Groundwater was abstracted from an AIW and sprayed on the water-curtain heating facility and then the used groundwater was injected into the same AIW well by the recharge system. Radon concentrations of fresh groundwater in the AIWs and of used groundwater in the injection tank were measured continuously using a continuous radon monitoring system. Radon concentrations of fresh groundwater in the AIWs and used groundwater in the injection tank were in the ranges of 10,830-13,530 Bq/m3 and 1500-5600 Bq/m3, respectively. A simple radon mass balance model was developed to estimate the recharge fraction of used groundwater in the AIWs. The recharge fraction in the 3 AIWs was in the range of 0.595-0.798. The time series recharge fraction could be obtained using the continuous radon monitoring system with a simple radon mass balance model. The results revealed that the radon mass balance model using continuous radon monitoring was effective for determining the time series recharge fractions in AIWs as well as for characterizing the recharge system. PMID- 27718383 TI - Considering DNA damage when interpreting mtDNA heteroplasmy in deep sequencing data. AB - Resolution of mitochondrial (mt) DNA heteroplasmy is now possible when applying a massively parallel sequencing (MPS) approach, including minor components down to 1%. However, reporting thresholds and interpretation criteria will need to be established for calling heteroplasmic variants that address a number of important topics, one of which is DNA damage. We assessed the impact of increasing amounts of DNA damage on the interpretation of minor component sequence variants in the mtDNA control region, including low-level mixed sites. A passive approach was used to evaluate the impact of storage conditions, and an active approach was employed to accelerate the process of hydrolytic damage (for example, replication errors associated with depurination events). The patterns of damage were compared and assessed in relation to damage typically encountered in poor quality samples. As expected, the number of miscoding lesions increased as conditions worsened. Single nucleotide polymorphisms (SNPs) associated with miscoding lesions were indistinguishable from innate heteroplasmy and were most often observed as 1-2% of the total sequencing reads. Numerous examples of miscoding lesions above 2% were identified, including two complete changes in the nucleotide sequence, presenting a challenge when assessing the placement of reporting thresholds for heteroplasmy. To mitigate the impact, replication of miscoding lesions was not observed in stored samples, and was rarely seen in data associated with accelerated hydrolysis. In addition, a significant decrease in the expected transition:transversion ratio was observed, providing a useful tool for predicting the presence of damage-induced lesions. The results of this study directly impact MPS analysis of minor sequence variants from poorly preserved DNA extracts, and when biological samples have been exposed to agents that induce DNA damage. These findings are particularly relevant to clinical and forensic investigations. PMID- 27718384 TI - Advanced midwifery practice: An evolutionary concept analysis. AB - AIM: the concept of 'advanced midwifery practice' is explored to a limited extent in the international literature. However, a clear conception of advanced midwifery practice is vital to advance the discipline and to achieve both internal and external legitimacy. This concept analysis aims to clarify advanced midwifery practice and identify its components. METHODS: a review of the literature was executed using Rodgers' evolutionary method of concept analysis to analyze the attributes, references, related terms, antecedents and consequences of advanced midwifery practice. RESULTS: an international consensus definition of advanced midwifery practice is currently lacking. Four major attributes of advanced midwife practitioners (AMPs) are identified: autonomy in practice, leadership, expertise, and research skills. A consensus was found on the need of preparation at master's level for AMPs. Such midwives have a broad and internationally varied scope of practice, fulfilling different roles such as clinicians, clinical and professional leaders, educators, consultants, managers, change agents, researchers, and auditors. Evidence illustrating the important part AMPs play on a clinical and strategic level is mounting. KEY CONCLUSIONS: the findings of this concept analysis support a wide variety in the emergence, titles, roles, and scope of practice of AMPs. Research on clinical and strategic outcomes of care provided by AMPs supports further implementation of these roles. As the indistinctness of AMPs' titles and roles is one of the barriers for implementation, a clear conceptualization of advanced midwifery practice seems essential for successful implementation. IMPLICATIONS FOR PRACTICE: an international debate and consensus on the defining elements of advanced midwifery practice could enhance the further development of midwifery as a profession and is a prerequisite for its successful implementation. Due to rising numbers of AMPs, extension of practice and elevated quality requirements in healthcare, more outcomes research exclusively evaluating the contribution of AMPs to healthcare becomes possible and desirable. PMID- 27718385 TI - Tuberculosis around the tarsal navicular: A rare entity. AB - Osteoarticular TB around the tarsal navicular is a chronic, uncommon condition affecting the midfoot, which causes significant morbidity to the patient. Tuberculosis around the tarsal navicular is rarely described in the literature. A series of three cases - two involving the talo-navicular joint and one involving the naviculo-cuneiform joint is described. Biopsy was used in all the cases for achieving diagnosis. All patients had good to fair outcome following medical management with anti-tubercular therapy. Due to the pauci-bacillary nature of the disease, a positive culture of the disease is not always possible. The diagnosis depends on a positive histopathology finding. Once an early diagnosis is achieved, antitubercular therapy is usually the mainstay. Clinical awareness of the rare presentations of this disease can help in early detection, adequate treatment and good to fair outcomes. Due to the destruction of the midfoot joints, some patients report difficulty in walking on uneven surfaces and barefoot, for which triple arthrodesis may be offered. PMID- 27718386 TI - The burden of diabetes-related foot disorders in community-dwellers living in rural Ecuador: Results of the Atahualpa Project. AB - BACKGROUND/OBJECTIVES: Prevalence of diabetes-related foot disorders (DRFD) in rural areas of developing countries is unknown. The burden of these conditions in Atahualpa, a rural Ecuadorian village, were assessed. METHODS: Using a population based design, Atahualpa residents aged >=40 years with diabetes mellitus were identified. Ankle brachial index determinations were used to assess presence of peripheral arterial disease, and the Michigan Neuropathy Screening Instrument was used to estimate peripheral neuropathy. Ulcers in the foot/ankle as well as history of amputations were considered as evidence of active diabetic foot disease. Using a linear model of risk, factors that independently correlated with DRFD, were assessed. RESULTS: Mean age of 110 participants was 64+/-12years (59% women). Peripheral arterial disease was diagnosed in 24% of cases and peripheral neuropathy in 59% (15% had both conditions). In the adjusted model, increasing age and being men increased the risk for DRFD. Active diabetic foot disease was noted in 7% of participants, and another 60% were at moderate-to-high risk for developing this complication (according to NHS Borders Foot Classification System). CONCLUSIONS: The prevalence of DRFD is high in rural Ecuador, and most of the affected individuals are at risk for developing active diabetic foot disease. PMID- 27718387 TI - The cross-cultural (transcultural) adaptation and validation of the nursing image questionnaire. AB - Education of nurses in the Republic of Croatia is being developed as a result of compliance with education in the European Union and the implementation of nursing research that leads to the growth of the whole profession. However, prejudice against the nursing profession is still present and therefore it is necessary to explore the attitudes of the general population and the population of nurses in the nursing profession in order to discover the causes of such prejudices and act on them. Therefore, the aim of this paper was to present transcultural adaptation and validation of the Nursing Image Questionnaire, which was created by Toth and associates (1998). The questionnaire, which includes 30 items and measures how an individual looks at the roles, values, and professional activities of nurses, was conducted as part of a preliminary study and was culturally adapted. The final study included 905 students who in 2011 and 2012 enrolled in the first year of full-time and part-time nursing study; the questionnaire was completed by 725 students. Toth and associates assumed that the attitude toward nursing is expressed as the sum of the responses of all the items, which would mean a factor structure with high item intercorrelation, but they also split the questionnaire into five thematic units. Results showed that, contrary to expectations, intercorrelations of items were extremely low and that following the completion of factor analysis, no satisfactory construct validity was established. From the obtained results, it can be concluded that it is not justified to create a latent dimension as established by research of Toth and associates, and the items, although there is a correlation between some of them, should be interpreted and analysed as independent constructs. PMID- 27718389 TI - Delay-distribution-dependent Hinfinity state estimation for delayed neural networks with (x,v)-dependent noises and fading channels. AB - This paper deals with the Hinfinity state estimation problem for a class of discrete-time neural networks with stochastic delays subject to state- and disturbance-dependent noises (also called (x,v)-dependent noises) and fading channels. The time-varying stochastic delay takes values on certain intervals with known probability distributions. The system measurement is transmitted through fading channels described by the Rice fading model. The aim of the addressed problem is to design a state estimator such that the estimation performance is guaranteed in the mean-square sense against admissible stochastic time-delays, stochastic noises as well as stochastic fading signals. By employing the stochastic analysis approach combined with the Kronecker product, several delay-distribution-dependent conditions are derived to ensure that the error dynamics of the neuron states is stochastically stable with prescribed Hinfinity performance. Finally, a numerical example is provided to illustrate the effectiveness of the obtained results. PMID- 27718388 TI - The role of galectin-1 in in vitro and in vivo photodynamic therapy with a galactodendritic porphyrin. AB - Conventional photodynamic agents used in clinic are porphyrin-based photosensitizers. However, they have low tumour selectivity, which may induce unwanted side-effects and damage to healthy tissues. In this study, we used a porphyrin with dendritic units of galactose (PorGal8) developed by us, which can target the galactose-binding protein, galectin-1, known to be overexpressed in many tumour tissues. In vitro and in vivo studies had been conducted for the validation of PorGal8 effectiveness. We showed a specific uptake of PorGal8 and induction of apoptotic cell death by generating oxidative stress and alterations in the cytoskeleton of bladder cancer cells overexpressing galectin-1. We further validated the photodynamic efficiency of PorGal8 in athymic nude mice (Balb/c nu/nu) bearing subcutaneously implanted luciferase-positive bladder cancer xenografts, overexpressing galectin-1 protein. PorGal8 (5 MUmol/kg, intraperitoneal), injected 24 h before light delivery (50.4 J/cm2), inhibited tumour growth. We conclude that the use of PorGal8 enables selective target and cytotoxicity by photodynamic therapy in cancer cells overexpressing galectin-1, preventing undesired phototoxicity in the surrounding healthy tissues. PMID- 27718390 TI - A neurodynamic approach to convex optimization problems with general constraint. AB - This paper presents a neurodynamic approach with a recurrent neural network for solving convex optimization problems with general constraint. It is proved that for any initial point, the state of the proposed neural network reaches the constraint set in finite time, and converges to an optimal solution of the convex optimization problem finally. In contrast to the existing related neural networks, the convergence rate of the state of the proposed neural network can be calculated quantitatively via the Lojasiewicz exponent under some mild assumptions. As applications, we estimate explicitly some Lojasiewicz exponents to show the convergence rate of the state of the proposed neural network for solving convex quadratic optimization problems. And some numerical examples are given to demonstrate the effectiveness of the proposed neural network. PMID- 27718391 TI - Multistability of complex-valued neural networks with discontinuous activation functions. AB - In this paper, based on the geometrical properties of the discontinuous activation functions and the Brouwer's fixed point theory, the multistability issue is tackled for the complex-valued neural networks with discontinuous activation functions and time-varying delays. To address the network with discontinuous functions, Filippov solution of the system is defined. Through rigorous analysis, several sufficient criteria are obtained to assure the existence of 25n equilibrium points. Among them, 9n points are locally stable and 16n-9n equilibrium points are unstable. Furthermore, to enlarge the attraction basins of the 9n equilibrium points, some mild conditions are imposed. Finally, one numerical example is provided to illustrate the effectiveness of the obtained results. PMID- 27718392 TI - A Self-Organizing Incremental Neural Network based on local distribution learning. AB - In this paper, we propose an unsupervised incremental learning neural network based on local distribution learning, which is called Local Distribution Self Organizing Incremental Neural Network (LD-SOINN). The LD-SOINN combines the advantages of incremental learning and matrix learning. It can automatically discover suitable nodes to fit the learning data in an incremental way without a priori knowledge such as the structure of the network. The nodes of the network store rich local information regarding the learning data. The adaptive vigilance parameter guarantees that LD-SOINN is able to add new nodes for new knowledge automatically and the number of nodes will not grow unlimitedly. While the learning process continues, nodes that are close to each other and have similar principal components are merged to obtain a concise local representation, which we call a relaxation data representation. A denoising process based on density is designed to reduce the influence of noise. Experiments show that the LD-SOINN performs well on both artificial and real-word data. PMID- 27718393 TI - The effects of fatigue on lower extremity kinematics, kinetics and joint coupling in symptomatic female runners with iliotibial band syndrome. AB - BACKGROUND: Altered hip and knee kinematics and joint coupling have been documented in runners with iliotibial band syndrome. Symptoms often present themselves after several minutes of running, yet the effect of fatigue warrants further exploration. The purpose of this study was to determine the effect of a run to fatigue in runners with iliotibial band syndrome, as compared to healthy controls. METHODS: Twenty uninjured and 12 female runners with iliotibial band syndrome performed a treadmill run to fatigue. Prior-to and following a run to fatigue, overground running data were collected. Variables of interest included stance phase: peak hip adduction and internal rotation, peak hip abductor and external rotator joint moments and frontal-sagittal plane hip and knee joint coupling. FINDINGS: Fatigue resulted in decreased peak hip adduction angles in injured runners. Fatigue did not affect injured runners differently than controls with respect to the remaining variables. Coupling differences did not exist between healthy and injured runners with respect to the loading or propulsive phases of stance. INTERPRETATION: While clinicians often strengthen hip abductor muscles and provide gait re-training to decrease stance phase hip adduction, our results suggest that, when exerted, female runners with iliotibial band syndrome independently modify their running gait to decrease hip adduction, potentially as a result of pain. Fatigue did not have an effect on the remaining study variables. It is possible that reducing the length of the iliotibial band through minimizing hip adduction reduces pain, but the other variables examined are not sensitive to this phenomenon.

AB - Glycosylation is one of the most common and important post-translational modifications, influencing both the chemical and the biological properties of proteins. Studying the glycosylation of the entire protein population of a sample can be challenging because variations in the concentrations of certain proteins can enhance or obscure changes in glycosylation. Furthermore, alterations in the glycosylation pattern of individual proteins, exhibiting larger variability in disease states, have been suggested as biomarkers for different types of cancer, as well as inflammatory and neurodegenerative diseases. In this paper, we present a rapid and efficient method for glycosylation analysis of individual proteins focusing on changes in the degree of fucosylation or other alterations to the core structure of the glycans, such as the presence of bisecting N acetylglucosamines and a modified degree of branching. Streptavidin-coated magnetic beads are used in combination with genetically engineered immunoaffinity binders, called VHH antibody fragments. A major advantage of the VHHs is that they are nonglycosylated; thus, enzymatic release of glycans from the targeted protein can be performed directly on the beads. After deglycosylation, the glycans are analyzed by MALDI-TOF-MS. The developed method was evaluated concerning its specificity, and thereafter implemented for studying the glycosylation pattern of two different proteins, alpha-1-antitrypsin and transferrin, in human serum and cerebrospinal fluid. To our knowledge, this is the first example of a protein array-type experiment that employs bead-based immunoaffinity purification in combination with mass spectrometry analysis for fast and efficient glycan analysis of individual proteins in biological fluid.

AB - Recently it has been demonstrated that catanionic mixtures of oppositely charged surfactants have improved physicochemical-biological properties compared to the individual components. Isotherms of mixtures of an anionic biosurfactant (lichenysin) and a cationic aminoacid surfactant (C3(LA)2) indicate a strong interaction suggesting the formation of a new "pseudo-surfactant". The antimicrobial properties of the mixture lichenysin and C3(LA)2 M80:20, indicate a synergistic effect of the components. The mechanism of action on the bacterial envelope was assessed by flow cytometry and Transmission Electron Microscopy.

AB - Hybrid nanoassemblies of ferritin and silica-supported lipid bilayers (ferritin SLBs) have been prepared and tested for the adhesion, spreading and proliferation of retinal microvascular endothelial cells (ECs). Lipid membranes with varying surface charge were obtained by mixing cationic 1-palmitoyl-2-oleoyl-sn-glycero-3 ethylphosphocholine (POEPC) with zwitterionic 1-palmitoyl-2-oleoyl-sn-glycero-3 phosphocholine (POPC) at increasing POPC/POEPC ratios. The supported bilayer formation and their subsequent interaction processes with ferritin were studied at the pH of 7.4 at different protein concentrations, by using the quartz crystal microbalance with dissipation monitoring and by atomic force microscopy. Both kinetics and viscoelastic parameters of the protein-lipid membrane interface were scrutinized, as well as surface coverage. Phase-contrast optical microscopy analyses of the ferritin-SLBs substrates after their interaction with endothelial cells evidenced the highest cell adhesion (2-4h of incubation time) and proliferation (from 24h to 5 days) for the membranes of POPC/POEPC (75:25 ratio). Moreover, ferritin increased both cell adhesion and proliferation in comparison to control glass (respectively 1.5- and 1.75-fold) as well as proliferation in comparison to bare POPC/POEPC (95:5 ratio) (2 fold). Results are very promising in the goal of modulating the endothelial cell response through the interplay of viscoelastic/charge properties of the solid-supported membranes and the SLB conditioned ferritin activity. PMID- 27718397 TI - Removal of nutrients from undiluted anaerobically treated piggery wastewater by improved microalgae. AB - This study aimed at improving the adaptability and biodegradability of tested microalgae in undiluted anaerobic fermentation slurry of piggery wastewater. For that, a two-stage method based on UV irradiation followed by gradual domestication was developed. The distinctness of this method was the elimination of a screening procedure and just needed the UV-irradiated cells with appropriate survival to be subjected to gradual domestication. The microalgae treated with the method not only grew well in undiluted slurry, but achieved outstanding removal efficiencies in total nitrogen (TN) and total phosphorus (TP). Large scale application was conducted in an open raceway pond, and the concentrations of TN and TP after treatment were 43.80mg/L (removal rate of 89.5%) and 5.83mg/L (removal rate of 85.3%) respectively, which greatly excelled the Chinese discharge standards for livestock and poultry wastewater. The strategy is therefore a promising method for microalgae to purify piggery slurry containing high nutrient contents. PMID- 27718398 TI - Effect of aeration rate on performance and stability of algal-bacterial symbiosis system to treat domestic wastewater in sequencing batch reactors. AB - This study investigated aeration rate (0, 0.2, 0.4 and 1.0L/min) effects on algal bacterial symbiosis (ABS) and conventional activated sludge (CAS) systems while treating domestic wastewater in sequencing batch reactors. Experiment results showed that ABS system performed better on NH4+-N, total nitrogen and total phosphorus removal than CAS system, especially under lower aeration rate condition (0.2Lair/min), with removal efficiencies improvements of 18.90%, 12.45% and 46.66%, respectively. The mechanism study demonstrated that a favorable aeration rate reduction (half of traditional value in CAS system) could enhance algae growth but weaken hydraulic shear force, which contributed to the interactions between algae and sludge flocs and further stability of ABS system. In addition, algae growth protected both ammonia and nitrite oxidizing bacteria from optical damage. It is expected that the present study would provide some new insights into ABS system and be helpful for development of low-energy demand wastewater treatment process.

AB - Biodiesel is a valuable alternative to fossil fuels and many countries choose biodiesel as an unconventional energy source. A large number of investigations have been done on microalgae as a source of oil production. In recent years, wastewater pollutions have caused many ecological problems, and therefore, wastewater phycoremediation has attracted the international attention. This paper studied the cultivation of Chlorella vulgaris in a crude oil polluted environment for biodiesel production. Intended concentrations were 10 and 20gperliter (crude oil/water) at two times. The results showed that the growth of C. vulgaris was improved in wastewater and the maximum amount of dry mass and oil was produced at the highest concentration of crude oil (0.41g and 0.15g/l, respectively). In addition, dry mass and oil yield of the microalga were significantly enhanced by increasing the experiment duration. PMID- 27718399 TI - Excellent N-fixing and P-solubilizing traits in earthworm gut-isolated bacteria: A vermicompost based assessment with vegetable market waste and rice straw feed mixtures. AB - Vermicomposting is a dependable waste recycling technology which greatly augments N and P levels mainly through microbial action. This paper aims to identify efficient N-fixing (NFB) and P-solubilizing (PSB) bacteria from earthworm intestines. Various combinations of vegetable market waste, rice straw, and cowdung were fed to two earthworm species (Eisenia fetida and Perionyx excavatus). Total organic C decreased, pH shifted towards neutrality, and NPK availability, and microbial (NFB, PSB, and total bacteria) population increased remarkably during vermicomposting with E. fetida. Therefore, 45 NFB and 34 PSB strains isolated from Eisenia gut were initially screened, their inter-dominance assessed, and 8 prolific strains were identified through 16SrRNA sequencing. Interestingly, two novel N-fixing strains of Kluyvera ascorbata emerged as an efficient biofertilizer candidate. Moreover, both N-fixing and P-solubilizing strains of Serratia and Bacillus were isolated from earthworm gut. All the isolated strains significantly improved soil health and facilitated crop growth as compared to commercial biofertilizers.

AB - An integrated process based on ionic liquids ([Bmim]Cl and [Bmim]OAc) pretreatment and successive alkali post-treatments (0.5, 2.0, and 4.0% NaOH at 90 degrees C for 2h) was performed to isolate lignins from Eucalyptus. The structural features and spatial distribution of lignin in the Eucalyptus cell wall were investigated thoroughly. Results revealed that the ionic liquids pretreatment promoted the isolation of alkaline lignin from the pretreated samples without obvious structural changes. Additionally, the integrated process resulted in syringyl-rich lignin macromolecules with more beta-O-4' linkages and less phenolic hydroxyl groups. Confocal Raman microscopy analysis showed that the dissolution behavior of lignin was varied in the morphologically distinct regions during the successive alkali treatments, and lignin dissolved was mainly stemmed from the secondary wall regions. These results provided some useful information for understanding the mechanisms of delignification during the integrated process and enhancing the potential utilizations of lignin in future biorefineries. PMID- 27718403 TI - Simultaneous production of proteases and antioxidant compounds from agro industrial by-products. AB - The use of processes for simultaneous production of bioproducts as enzymes and bioactive compounds is an interesting alternative to reduce environmental impacts. Thus, the aim of this study was to produce simultaneously, using the biorefinery concept, both proteases and bioactive compounds with antioxidant activity from Bacillus sp. P45 cultivation by using different by-products. The integrated process developed in this study enabled to obtain enzymes with proteolytic and keratinolytic properties in a process with alternate substrates from agro-industrial by-products (feather meal, residual feather meal and biomass), thus, creating an interesting alternative to managing them. The residual biomass provided the highest protease activity (1306.6U/mL) and the reused feather meal reached the highest keratinolytic activity (89U/mL), both at 32h of cultivation. Moreover, hydrolysates produced in cultivation using feather meal and residual biomass had high antioxidant activity, they have great potential as natural antioxidants. PMID- 27718402 TI - Biodegradation of petroleum hydrocarbons by oleophilic strain of Pseudomonas aeruginosa NCIM 5514. AB - The aim of this work was to study the potential of an indigenous strain of Pseudomonas aeruginosa NCIM 5514, isolated from petroleum-polluted soil, for the biodegradation of crude petroleum oil. The isolate completely decolorized 2,6 dichlorophenol indophenol in 120h when grown at (37+/-1 degrees C), indicating its hydrocarbon utilizing nature. Ex situ biodegradation study was performed to find out quantitative utilization and biodegradation of paraffin(s) present in crude oil. When the culture was grown in Bushnell-Hass medium containing crude oil (3%,v/v) at 37 degrees C, 180rpm for 60days, the viscosity of the oil was reduced from 1883cp to 1002cp. Gravimetric and gas chromatographic analysis showed 61.03% and 60.63% of biodegradation of C8-C36+ hydrocarbons, respectively. These results indicated that the isolate has potential to be used for ex-situ and in-situ bioremediation of hydrocarbon pollutants and could have promising applications in petrochemical industry. PMID- 27718404 TI - Clarification of phosphorus fractions and phosphorus release enhancement mechanism related to pH during waste activated sludge treatment. AB - This study aimed to clarify phosphorus (P) fractions in waste activated sludge (WAS) and explore release performance and enhancement mechanism of different P species related to pH. Results showed that inorganic P (IP) was the major P fraction in raw sludge (87.86% of total solid P), and non-apatite inorganic P (NAIP), the most labile P forms, occupied 81.30% of IP, suggesting that WAS could be selected as potential substitution of phosphate rock. The optimized acid and alkaline conditions were pH=4 and pH=12 for molybdate reactive P accumulation, increased by 311.20mg/L and 479.18mg/L compared to raw sludge, which were 3.80 and 5.84 times higher than that of control, respectively. The mechanism study demonstrated that high pH promoted NAIP release, and apatite P was sensitive to low pH. Moreover, the releasable and recoverable P depended on both fractions of different P species in sludge and pH adjustment for sludge treatment. PMID- 27718405 TI - Electricity generation from macroalgae Enteromorpha prolifera hydrolysates using an alkaline fuel cell. AB - The goal of this work was to develop a method for the direct power generation using macroalgae Enteromorpha prolifera. The process conditions for the saccharification of macroalgae were optimized and a type of alkaline fuel cell contained no precious metal catalysts was developed. Under optimum conditions (170 degrees C and 2% hydrochloric acid for 45min), dilute acid hydrolysis of the homogenized plants yielded 272.25g reducing sugar/kg dry algal biomass. The maximum power density reached 3.81W/m2 under the condition of 3M KOH and 18.15g/L reducing sugar in hydrolysate, higher than any other reported algae-fed fuel cells. This study represents the first report on direct electricity generation from macroalgae using alkaline fuel cells, suggesting that there is great potential for the production of renewable energy using marine biomass. PMID- 27718406 TI - Crossing the invisible line: De-differentiation of wake, sleep and dreaming may engender both creative insight and psychopathology. AB - Writing about dreaming, the poet Raymond Carver said "I feel as if I've crossed some kind of invisible line". In creative people, the "line" between wake, dreaming and psychopathology may be porous, engendering a de-differentiated, super-critical, hybrid state. Evidence exists for a relationship between creativity and psychopathology but its nature has been elusive. De differentiation between wake, sleep and dreaming may be the common substrate, as dream-like cognition pervades wake and wake-like neurophysiology suffuses sleep. Chaos theory posits brain states as inherently labile, transient and dynamically unstable. Over and above transient dissociations, an enduring and, sometimes, progressive, de-differentiation may be possible. Evidence indicates that sleep and dreaming facilitate creative insight. In consequence, a mild to moderate form of de-differentiation may enhance creativity but if wake-like neurobiology permeates sleep this may disrupt sleep-dependent memory processing and emotional regulation. If de-differentiation is progressive and enduring, various forms of psychopathology may result. PMID- 27718407 TI - A template model of embodiment while dreaming: Proposal of a mini-me. AB - Dreams are usually centered around a dream self capable of tasks generally impossible in waking, e.g. flying or walking through walls. Moreover, the bodily dream self appears relatively stable and insensitive to changes of the embodied wake self, raising the question of whether and to what extent the dream self is embodied. To further explore its determinants, we tested whether the dream self would be affected by either pre-sleep focused attention to a body part or by its experimental alteration during the day. Choosing a repeated-measures design, we analyzed how often key words reflecting the experimental manipulations appeared in the dream reports. Results suggest that the dream self is not affected by these manipulations, strengthening the hypothesis that, in the majority of dreams, the dream self is only weakly embodied, utilizing a standard template of embodiment akin to a prototype of self operating independently from the physical waking self. PMID- 27718408 TI - Flexible thin-layer plasma inactivation of bacteria and mold survival in beef jerky packaging and its effects on the meat's physicochemical properties. AB - The aims of the present study were to examine the use of a flexible thin-layer plasma system in inactivating bacteria and mold on beef jerky in a commercial package and to evaluate the physicochemical changes of the jerky. After plasma treatment for 10min, Escherichia coli O157:H7, Listeria monocytogenes, Salmonella Typhimurium, and Aspergillus flavus populations on the beef jerky were reduced by approximately 2 to 3Log CFU/g. No significant changes in metmyoglobin content, shear force, and myofibrillar fragmentation index were found in the plasma treated beef jerky. On the other hand, the peroxide content and L* value were decreased whereas the a* and DeltaE value were increased in the plasma-treated sample. Sensory evaluation indicated negative effects of plasma treatment on flavor, off-odor, and overall acceptability of the beef jerky. In conclusion, the flexible thin-layer plasma system could be employed as a means for decontamination of beef jerky, with slight changes to the physicochemical quality of the product. PMID- 27718409 TI - New phagotrophic euglenoid species (new genus Decastava; Scytomonas saepesedens; Entosiphon oblongum), Hsp90 introns, and putative euglenoid Hsp90 pre-mRNA insertional editing. AB - We describe three new phagotrophic euglenoid species by light microscopy and 18S rDNA and Hsp90 sequencing: Scytomonas saepesedens; Decastava edaphica; Entosiphon oblongum. We studied Scytomonas and Decastava ultrastructure. Scytomonas saepesedens feeds when sessile with actively beating cilium, and has five pellicular strips with flush joints and Calycimonas-like microtubule-supported cytopharynx. Decastava, sister to Keelungia forming new clade Decastavida on 18S rDNA trees, has 10 broad strips with cusp-like joints, not bifurcate ridges like Ploeotia and Serpenomonas (phylogenetically and cytologically distinct genera), and Serpenomonas-like feeding apparatus (8-9 unreinforced microtubule pairs loop from dorsal jaw support to cytostome). Hsp90 and 18S rDNA trees group Scytomonas with Petalomonas and show Entosiphon as the earliest euglenoid branch. Basal euglenoids have rigid longitudinal strips; derived clade Spirocuta has spiral often slideable strips. Decastava Hsp90 genes have introns. Decastava/Entosiphon Hsp90 frameshifts imply insertional RNA editing. Petalomonas is too heterogeneous in pellicle structure for one genus; we retain Scytomonas (sometimes lumped with it) and segregate four former Petalomonas as new genus Biundula with pellicle cross section showing 2-8 smooth undulations and typified by Biundula (=Petalomonas) sphagnophila comb. n. Our taxon-rich site-heterogeneous rDNA trees confirm that Heteronema is excessively heterogeneous; therefore we establish new genus Teloprocta for Heteronema scaphurum. PMID- 27718410 TI - Interictal irritability and associated factors in epilepsy patients. AB - PURPOSE: Irritability has been reported in epilepsy patients. We identified associated factors for interictal irritability in epilepsy patients. METHOD: Adult epilepsy patients who received antiepileptic drugs (AEDs) for at least 1year were invited to participate in this study. For eligible patients, several questionnaires, such as the Irritability in Adult Patients with Epilepsy (I-Epi), the Korean version of the Neurological Disorders Depression Inventory for Epilepsy (K-NDDI-E), the Generalized Anxiety Disorder-7 (GAD-7), the Epworth Sleepiness Scale (ESS), and the Insomnia Severity Index (ISI), were administered. We investigated factors for determining the overall I-Epi score using univariate and multivariate analyses. RESULTS: A total of 276 patients with epilepsy were included in the study. Mean duration of epilepsy was 15.4 years (2-58 years), and 146 patients (52.9%) had a seizure freedom for 1year. Mean overall I-Epi score was 46.1 (18-105), and 163 patients (59.1%) had at least a moderate level of irritability. Although several factors, including demographic, socioeconomic, psychosomatic, epilepsy-related factors, and levetiracetam intake, were associated with the overall I-Epi score, the strongest factor was the K-NDDI-E score, followed by the ISI score, the GAD-7 score, the ESS score, seizure control, and duration of epilepsy. CONCLUSION: An appropriate management of psychosomatic problems and epileptic attacks is likely to reduce irritability in epilepsy patients. Acknowledgment of irritability by clinicians will reduce drug failure when they administer AEDs with negative psychotropic profiles, especially irritability and aggression. PMID- 27718412 TI - Early fluid resuscitation and volume therapy in venoarterial extracorporeal membrane oxygenation. AB - PURPOSE: For circulatory support, venoarterial extracorporeal membrane oxygenation (VA-ECMO) is dependent on sufficient venous drainage ensured by fluid therapy. Volume overload however is linked to poor prognosis. This study therefore evaluates volume therapy in VA-ECMO. MATERIAL AND METHODS: We report data of a single center registry of all patients after VA-ECMO implantation treated between 2010 and 2015. RESULTS: A total of 195 patients were included in this registry with a medium age of 58.2 +/- 1.1 years, 71.8% were male. A positive fluid balance was detected in 94.7% at day 1 (day 2: 93.7%, day 3: 92.6%). Consistently, survivors had a lower fluid balance when compared to non survivors (P < .001). Three hours post-implantation, patients above the 75th percentile had a hazard ratio of 6.03 when compared to average survival (P < .05). AUC at that time point was 0.726 as calculated by ROC. Patients below the 50th percentile (fluid balance below 8500 mL after 24 hours) had the best prognosis after VA-ECMO implantation (P < .001). CONCLUSIONS: Higher fluid balance was consistently linked to poor survival. We found no evidence to support a liberal fluid therapy in VA-ECMO patients, especially not the early after implantation. With a retrospective study, one cannot clarify if lower fluid balance might improve outcomes or represents a prognostic marker. PMID- 27718411 TI - Hematologic counts as predictors of delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage. AB - PURPOSE: Aneurysmal subarachnoid hemorrhage (SAH) is associated with high morbidity and mortality, but currently no single clinical method or ancillary test can reliably predict which subset of patients will develop delayed cerebral ischemia (DCI). The aim of this study was to find hematologic derangements and clinical factors present during the first 7 days after bleeding that could help identify patients at risk for development of DCI. MATERIALS AND METHODS: Databank analysis of patients with SAH admitted between 2010 and 2012 in a single center. Data from demographics, imaging, laboratory, and clinical factors were collected. Statistical testing was conducted to test for association to the outcome, and multivariate logistic regression was used to design a predictive model. RESULTS: Of 55 patients, 14 developed DCI (25%). Anemia and leukocytosis on the third day after bleeding were significantly correlated with the outcome (for anemia: P<.032; confidence interval, 1.12-15.16; odds ratio, 4.12; for leukocytosis: P<.046; confidence interval, 1.03-26.13; odds ratio, 5.18). Anemia and leukocytosis were still statistically significant after adjustment for age, sex, modified Fisher scale, and Hunt-Hess scale. CONCLUSION: The presence of leukocytosis and anemia during the third day after SAH was statistically correlated with the occurrence of DCI. PMID- 27718413 TI - Exploring the scope of new arylamino alcohol derivatives: Synthesis, antimalarial evaluation, toxicological studies, and target exploration. AB - Synthesis of new 1-aryl-3-substituted propanol derivatives followed by structure activity relationship, in silico drug-likeness, cytotoxicity, genotoxicity, in silico metabolism, in silico pharmacophore modeling, and in vivo studies led to the identification of compounds 22 and 23 with significant in vitro antiplasmodial activity against drug sensitive (D6 IC50 <= 0.19 MUM) and multidrug resistant (FCR-3 IC50 <= 0.40 MUM and C235 IC50 <= 0.28 MUM) strains of Plasmodium falciparum. Adequate selectivity index and absence of genotoxicity was also observed. Notably, compound 22 displays excellent parasitemia reduction (98 +/- 1%), and complete cure with all treated mice surviving through the entire period with no signs of toxicity. One important factor is the agreement between in vitro potency and in vivo studies. Target exploration was performed; this chemotype series exhibits an alternative antimalarial mechanism. PMID- 27718415 TI - Cross section measurement of alpha particle induced nuclear reactions on natural cadmium up to 52MeV. AB - Cross sections of alpha particle induced nuclear reactions have been measured on thin natural cadmium targets foils in the energy range from 11 to 51.2MeV. This work was a part of our systematic study on excitation functions of light ion induced nuclear reactions on different target materials. Regarding the cross sections, the alpha induced reactions are not deeply enough investigated. Some of the produced isotopes are of medical interest, others have application in research and industry. The radioisotope 117mSn is a very important theranostic (therapeutic + diagnostic) radioisotope, so special care was taken to the results for that isotope. The well-established stacked foil technique followed by gamma spectrometry with HPGe gamma spectrometers were used. The target and monitor foils in the stack were commercial high purity metal foils. From the irradiated targets 117mSn, 113Sn, 110Sn, 117m,gIn, 116mIn, 115mIn, 114mIn, 113mIn, 111In, 110m,gIn, 109mIn, 108m,gIn, 115gCd and 111mCd were identified and their excitation functions were derived. The results were compared with the data of the previous measurements from the literature and with the results of the theoretical nuclear reaction model code calculations TALYS 1.8 (TENDL-2015) and EMPIRE 3.2 (Malta). From the cross section curves thick target yields were calculated and compared with the available literature data. PMID- 27718414 TI - Reductions in experiential avoidance as a mediator of change in symptom outcome and quality of life in acceptance-based behavior therapy and applied relaxation for generalized anxiety disorder. AB - As a field, we lack information about specific mechanisms that are responsible for changes that occur over the course of treatments for anxiety disorders (Kazdin, 2007). Identifying these mechanisms would help streamline evidence-based approaches, increase treatment response rates, and aid in the dissemination and implementation of evidence-based approaches in diverse contexts. The current study examined reductions in experiential avoidance (EA; Hayes, Wilson, Gifford, Follette, & Strosahl, 1996), attempts to control or eliminate distressing internal experiences, regardless of behavioral consequences, as a potential mechanism of change in participants with a principal diagnosis of generalized anxiety disorder (GAD) receiving either acceptance-based behavior therapy (ABBT) or applied relaxation (AR). Participants' EA scores across treatment on the Acceptance and Action Questionnaire (AAQ) were used to calculate slopes, which were used as predictors in a series of linear regressions. Greater change in EA across treatment significantly predicted change in worry (PSWQ) and quality of life (QOLI) across both treatments. These results contribute to the body of literature on common mechanisms of change across traditional CBTs and mindfulness and acceptance-based approaches. PMID- 27718416 TI - When pathological and radiological correlation is achieved, excision of fibroadenoma with lobular neoplasia on core biopsy is not warranted. AB - BACKGROUND: The diagnosis and management of lobular neoplasia (LN) including lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) remains controversial. Current management options after a core needle biopsy (CNB) with lobular neoplasia (LN) incorporating both ALH and LCIS include excision biopsy or careful clinical and radiologic follow up. METHODS: A retrospective analysis of the surgical database at Cork University Hospital was performed to identify all core needle biopsies from January 1st 2010 to 31st December 2013 with a diagnosis of FA who subsequently underwent surgical excision biopsy. All cases with associated LN including ALH and classical LCIS were selected. We excluded cases with coexistent ductal carcinoma in situ (DCIS), invasive carcinoma, LN associated with necrosis, pleomorphic lobular carcinoma in situ (PLCIS) or lesions which would require excision in their own right (papilloma, radial scar, atypical ductal hyperplasia (ADH) or flat epithelial atypia (FEA)). Cases in which the radiologic targeted mass was discordant with a diagnosis of FA were also excluded. RESULTS: 2878 consecutive CNB with a diagnosis of FA were identified. 25 cases had a diagnosis of concomitant ALH or classical LCIS. Our study cohort consisted of 21 women with a mean age 53 years (age range 41-70 years). The core biopsy diagnosis was of LCIS and FA in 16 cases and ALH and FA in 5 cases. On excision biopsy, a FA was confirmed in all 21 cases. In addition to the FA, residual LCIS was present in 14 cases with residual ALH in 2 cases. One of the twenty-one cases (4.8%) was upgraded to invasive ductal carcinoma on excision. PMID- 27718417 TI - Initial experience of automated breast volume scanning (ABVS) and ultrasound elastography in predicting breast cancer subtypes and staging. AB - OBJECTIVES: Breast cancer is a heterogeneous disease consisting of distinct histopathological subtypes with different clinical outcomes. In this article, we identified the automated breast volume scanning (ABVS) and shear wave velocity (SWV) characteristics of different pathological types of breast carcinoma. METHODS: A retrospective review of both ABVS and SWV imaging of 118 consecutive breast masses was performed. The imaging features of both techniques were assessed with reference to histopathological results. RESULTS: Echo heterogeneity with a smooth and lobulated margin was a significant feature more frequently found in mucinous carcinoma groups (100%, P < 0.05). Between different stages of ductal carcinoma, echo homogeneity was more likely in high-grade ductal carcinomas (P < 0.05). SWV differences existed between inside tumor areas and either tumor boundary or tissues outside the tumors (P < 0.05), and values differed between different breast carcinoma stages. The central and tumor margin areas of ductal carcinomas were much harder than in tubular carcinoma and micro carcinoma, respectively (P < 0.05). SWV ROC curve analyses yielded a cut-off value of 3.015 m/s between ductal carcinoma in situ (DCIS) and invasive ductal carcinoma in the central part of lesions, with 83.5% sensitivity and 80% specificity for T0 vs T1-3 staging. CONCLUSIONS: Since some features were associated with different breast carcinoma types and stages, ABVS and SWV imaging has the potential to give clues about breast carcinoma differentiation in a non invasive manner. PMID- 27718418 TI - Comparative effects of Ni(II) and Cu(II) ions and their combinations on redox potential and hydrogen photoproduction by Rhodobacter sphaeroides. AB - The aim of the present work was the study of comparative effects of Cu(II) and Ni(II) and their mixture on growth, redox potential, hydrogen (H2) yield and ATPase activity in phototrophic purple bacteria R. sphaeroides MDC6522 from Jermuk mineral spring in Armenia. It was ascertained, that Cu2+ and Ni2+ have different effects on bacterial specific growth rate: in the presence of 5MUM Cu2+ growth rate was ~3.2-fold lower in comparison with control (no addition), and increased ~1.5-fold in medium with 5MUM Ni2+. These changes may be resulted by action of the ions on redox potential (Eh). Low concentrations of Ni2+ had an enhancing effect on the Eh drop and H2 production. The increase of concentration from 1 to 5MUM enhanced the stimulatory effect of Ni2+. H2 yield in R. sphaeroides (72h of growth) was enhanced ~3-fold with 5MUM Ni2+, whereas in the presence of 5MUM Cu2+ H2 yield was ~1.2 fold lower in comparison with control. Cu2++Ni2+ combinations effects were differed from the effect when ions used separately. When Cu2+ and Ni2+ were added together, the Ni2+ stimulatory effect disappeared, which indicated that heavy metal ions mixture may have different action mechanisms. Moreover, N,N'-dicyclohexylcarbodiimide-sensitive ATPase activity of R. sphaeroides membrane vesicles has been increased in the presence of both ions, but in the presence of Su2+ the influence was feebly marked in comparison with Ni2+. The results suggest an interaction between these ions and the FOF1-ATPase. Thus, the results obtained point out discrimination between Cu2+ and Ni2+ and their combinations effects and reveal new regulatory pathways to enhance H2 yield in R. sphaeroides. PMID- 27718419 TI - Spectroscopic characterization of the effect of mouse twinfilin-1 on actin filaments at different pH values. AB - The effect of mammalian twinfilin-1 on the structure and dynamics of actin filaments were studied with steady state fluorescence spectroscopy, total internal reflection fluorescence microscopy and differential scanning calorimetry techniques. It was proved before that the eukaryotic budding yeast twinfilin-1 can efficiently bind and severe actin filaments in vitro at low pH values. In the present work steady-state anisotropy measurements revealed that twinfilin can bind efficiently to F-actin. Dilution-induced depolymerization assay proved that mammalian twinfilin-1 has an actin filament severing activity. This severing activity was more pronounced at low pH values. Total internal reflection fluorescence microscopy measurements could support the severing activity of mouse twinfilin-1. The average rate of depolymerization was more apparent at low pH values. The differential scanning calorimetry measurements demonstrated that mammalian twinfilin-1 could reduce the stiffness within the actin filaments before the detachment of the actin protomers. The structural and dynamic reorganization of actin can support the twinfilin-1 induced separation of actin protomers. The measured data indicated that mammalian twinfilin-1 was able to accelerate the monomers dissociation and/or sever the filaments effectively at low pH values. It was concluded that twinfilin-1 can affect the F-actin in biological processes or under stress situations when the pH is markedly under the physiological level. PMID- 27718420 TI - Near-infrared laser increases MDPC-23 odontoblast-like cells proliferation by activating redox sensitive pathways. AB - Near infrared laser is known to induce biostimulatory effects, resulting in cell proliferation enhancement. Although such positive effect is widely exploited in various clinical applications, molecular mechanisms involved are still poorly understood. The aim of the study was to investigate the ability of laser stimulation to increase cell proliferation through an early activation of three redox sensitive pathways, namely Nrf-2, NF-kappaB and ERK in a rat odontoblast like cell line (MDPC-23 cells). MDPC-23 cells were irradiated with different energy settings (0-50J, corresponding to 0-32.47J/cm2) and cell proliferation was evaluated by cell counting. Nrf-2, NF-kappaB and ERK signaling pathways activation was investigated through Western blot analysis. Our results show that a single 25J laser stimulation is able to increase cell proliferation and that this effect could be increased by repeating the stimulation twice with a time lapse of 24h. Western blot experiments demonstrated that laser stimulation is able to induce an early activation response in intracellular signaling, with an overlapping time pattern between the three considered pathways. Results discussed in this paper reveal a complex mechanism underlying near-infrared induced increase in pre-odontoblasts proliferation, involving three survival pathways that can act both separately or through reciprocal crosstalk. In particular, data presented suggest an important role for ERK pathway that could act directly by stimulating cell proliferation but can also induce both Nrf-2 and NF-kappaB activation, acting as a critical cellular checkpoint in response to imbalanced redox state generated by a laser induced increase in ROS production. PMID- 27718421 TI - DNA damage protecting and free radical scavenging properties of mycosporine-2 glycine from the Dead Sea cyanobacterium in A375 human melanoma cell lines. AB - Mycosporine-like amino acids (MAAs) are a group of natural sunscreen compounds that possess highly photoprotective properties. The most commonly found MAAs in marine organisms is shinorine, porphyra-334, and mycosporine-glycine. However, the halophilic species accumulate mycosporine-2-glycine (M2G) as the major MAA. In this study, we have investigated the protective effect of M2G against oxidative stress. In vitro radical scavenging activity revealed that M2G exhibited a significant inhibition with scavenging concentration (SC) 50 value of 22+/-1.4MUM. In vivo analysis using the human melanoma A375 and a control cell line (NHSF) showed that M2G at low concentration (i.e. micromolar range) protected the cells against the oxidative stress (H2O2)-induced cell death. Comet assay to assess total DNA strand breaks demonstrated that M2G was not genotoxic and protected against the DNA damage by H2O2 treatment at the same level as ascorbic acid. To our knowledge, this is the first evidence demonstrating potential protective role of the natural sunscreen compound M2G against oxidative stress-induced DNA damage in human cell lines. The potent antioxidant activity combined with DNA protection ability of M2G may support its endorsement as a potential natural sunscreen with antioxidant property. These findings provide important clues for possible use of M2G in pharmaceutical and biotechnological applications. PMID- 27718422 TI - Low episodic memory performance in cognitively normal elderly subjects is associated with increased posterior cingulate gray matter N-acetylaspartate: a 1H MRSI study at 7 Tesla. AB - Low episodic memory performance characterizes elderly subjects at increased risk for Alzheimer's disease (AD) and may reflect neuronal dysfunction within the posterior cingulate cortex and precuneus (PCP) region. To investigate a potential association between cerebral neurometabolism and low episodic memory in the absence of cognitive impairment, tissue-specific magnetic resonance spectroscopic imaging at ultrahigh field strength of 7 Tesla was used to investigate the PCP region in a healthy elderly study population (n = 30, age 70 +/- 5.7 years, Mini Mental State Examination 29.4 +/- 4.1). The Verbal Learning and Memory Test (VLMT) was administered as part of a neuropsychological battery for assessment of episodic memory performance. Significant differences between PCP gray and white matter could be observed for glutamate-glutamine (p = 0.001), choline (p = 0.01), and myo-inositol (p = 0.02). Low Verbal Learning and Memory Test performance was associated with high N-acetylaspartate in PCP gray matter (p = 0.01) but not in PCP white matter. Our data suggest that subtle decreases in episodic memory performance in the elderly may be associated with increased levels of N acetylaspartate as a reflection of increased mitochondrial energy capacity in PCP gray matter. PMID- 27718423 TI - Fine-mapping the effects of Alzheimer's disease risk loci on brain morphology. AB - The neural substrate of genetic risk variants for Alzheimer's disease (AD) remains unknown. We studied their effect on healthy brain morphology to provide insight into disease etiology in the preclinical phase. We included 4071 nondemented, elderly participants of the population-based Rotterdam Study who underwent brain magnetic resonance imaging and genotyping. We performed voxel based morphometry (VBM) on all gray-matter voxels for 19 previously identified, common AD risk variants. Whole-brain expression data from the Allen Human Brain Atlas was used to examine spatial overlap between VBM association results and expression of genes in AD risk loci regions. Brain regions most significantly associated with AD risk variants were the left postcentral gyrus with ABCA7 (rs4147929, p = 4.45 * 10-6), right superior frontal gyrus by ZCWPW1 (rs1476679, p = 5.12 * 10-6), and right postcentral gyrus by APOE (p = 6.91 * 10-6). Although no individual voxel passed multiple-testing correction, we found significant spatial overlap between the effects of AD risk loci on VBM and the expression of genes (MEF2C, CLU, and SLC24A4) in the Allen Brain Atlas. Results are available online on www.imagene.nl/ADSNPs/. In this single largest imaging genetics data set worldwide, we found that AD risk loci affect cortical gray matter in several brain regions known to be involved in AD, as well as regions that have not been implicated before. PMID- 27718424 TI - Anxiety and autonomic response to social-affective stimuli in individuals with Williams syndrome. AB - BACKGROUND: Williams syndrome (WS) is a genetic condition characterized by an unusual "hypersocial" personality juxtaposed by high anxiety. Recent evidence suggests that autonomic reactivity to affective face stimuli is disorganised in WS, which may contribute to emotion dysregulation and/or social disinhibition. METHODS: Electrodermal activity (EDA) and mean interbeat interval (IBI) of 25 participants with WS (19 - 57 years old) and 16 typically developing (TD; 17-43 years old) adults were measured during a passive presentation of affective face and voice stimuli. The Beck Anxiety Inventory was administered to examine associations between autonomic reactivity to social-affective stimuli and anxiety symptomatology. RESULTS: The WS group was characterized by higher overall anxiety symptomatology, and poorer anger recognition in social visual and aural stimuli relative to the TD group. No between-group differences emerged in autonomic response patterns. Notably, for participants with WS, increased anxiety was uniquely associated with diminished arousal to angry faces and voices. In contrast, for the TD group, no associations emerged between anxiety and physiological responsivity to social-emotional stimuli. CONCLUSIONS: The anxiety associated with WS appears to be intimately related to reduced autonomic arousal to angry social stimuli, which may also be linked to the characteristic social disinhibition. PMID- 27718425 TI - Bacterial disinfection in a sunlight/visible-light-driven photocatalytic reactor by recyclable natural magnetic sphalerite. AB - A 5-L reactor was designed and used to enhance the sunlight/visible-light-driven (VLD) photocatalytic disinfection efficiency towards Gram-negative bacterium (Escherichia coli). Natural magnetic sphalerite (NMS) was used as the photocatalyst, which could be easily recycled by applying a magnetic field. Results showed that NMS with irradiation by the blue light emitting diode (LED) lamp could completely inactivate 1.5 * 105 cfu/mL of E. coli within 120 min in the first three runs. However, the inactivation efficiency of E. coli started to decrease in the 4th Run, while in the 5th run, the E. coli with the initial concentration of 5 logs was inactivated to 3.3 (blue-light) and 3.5 logs (sunlight), respectively. Moreover, the stability and deactivation mechanism of NMS during subsequent runs were also studied. The results showed that the decline of the photocatalytic activity was possibly attributed to adsorption of the bacterial decomposed compounds on the active sites. In addition, photocatalytic bactericidal mechanism of the NMS in the photocatalytic system was investigated by using multiple scavengers to remove the specific reactive species. Moreover, various Gram-positive bacteria including Staphylococcus aureus, Microbacterium barkeri, and Bacillus subtilis could also be efficiently inactivated in the photocatalytic system. PMID- 27718426 TI - Hair chemical element contents and influence factors of reproductive-age women in the West Ujimqin Banner, Inner Mongolia, China. AB - Women have an increased risk for chemical element deficiencies during reproductive age, particularly due to higher chemical element requirements and poor diets. Twenty-one chemical elements (Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Se, Si, Sn, Sr, Ti, V and Zn) in hair samples, which were collected from 71 non-pregnant and 236 pregnant women living in the West Ujimqin Banner, central Inner Mongolia, China, were measured, and the environment, dietary habits and ethnic group influence factors associated with the biomarker were analyzed. The results indicated that the average values of the chemical element contents from hair were greatly different compared to those from other areas, especially the Al, Cd, Pb, Ca and Sr contents. There was no significant difference among the three ethnicities for any element except Mn and Ti in non pregnant women. Compared to non-pregnant women, in the first trimester group, the levels of nine chemical elements (Ba, Cd, Cu, Pb, Se, Si, Sn and Ti) decreased, while the others increased, and the contents of all of the chemical elements decreased in the second trimester group, while in the third trimester, there was a slight increase. Three chemical elements (Cu, Mn and Zn) displayed a synergistic correlation between each other in the third trimester group, which may protect the placenta from some oxidant damage. The high levels of Cd and Pb in hair likely originate from house renovations and traffic pollution. This study provided basic and useful information on the levels of chemical elements in reproductive-age women, and the results of this study are helpful to control the contents and improve the health of pregnant and non-pregnant women. PMID- 27718427 TI - Accumulation and developmental toxicity of hexabromocyclododecanes (HBCDs) on the marine copepod Tigriopus japonicus. AB - The brominated flame retardants hexabromocyclododecanes (HBCDs) are ubiquitous environmental contaminants, widely distributed in aquatic systems including the marine environment and marine organisms. HBCDs are toxic to the development of both freshwater and marine fish. However, the impacts of HBCDs on marine invertebrates are not well known. In this study, the marine copepod, Tigriopus japonicus, was used to assess the bioaccumulation and developmental toxicity of technical HBCD (tHBCD) through water-borne exposure. The uptake rate constant of tHBCD by T. japonicus was high, which resulted in high bioaccumulation potential. The bioconcentration factors of tHBCD were 8.73 * 104 and 6.34 * 104 L kg-1 in T. japonicus, calculated using the kinetic and steady-state methods, respectively. Exposure of T. japonicus nauplii to tHBCD caused significant growth delay. The lowest-observable-effect-concentrations of tHBCD induced developmental delay were 30 and 8 MUg L-1 for the F0 and F1 generations, respectively, which suggested that the F1 generation was more sensitive to tHBCD than the F0 generation and warranted multiple-generation toxicity tests for future studies. Furthermore, exposure of the adult copepods to tHBCD induced the transcription of oxidative stress response genes and apoptotic genes, e.g., SOD,CAT, GST, OGG1, P53 and Caspase-3. It was therefore speculated that tHBCD exposure induced the generation of reactive oxygen species in T. japonicus, which activated the oxidative stress defense genes and meanwhile resulted in oxidative DNA damage. The damaged DNA activated the transcription of p53 and triggered the caspase-mediated apoptosis pathway, which may be the reason for the tHBCD induced developmental delay in T. japonicus nauplii. PMID- 27718428 TI - Zero-valent iron for the abatement of arsenate and selenate from flowback water of hydraulic fracturing. AB - Zero-valent iron (ZVI) was tested for the removal of 150 MUg L-1 As(V) and 350 MUg L-1 Se(VI) in high-salinity (ionic strength 0.35-4.10 M) flowback water of hydraulic fracturing. Over 90% As(V) and Se(VI) was removed by 2.5 g L-1 ZVI in Day-14 flowback water up to 96-h reaction, with the remaining concentration below the maximum contaminant level for As(V) and criterion continuous concentration for Se(VI) recommended by US EPA. The kinetics of As(V) and Se(VI) removal followed a pseudo-second-order rate expression with the observed rates of 4.51 * 10-2-4.91 * 10-1 and 3.48 * 10-2-6.58 * 10-1 h-1 (with 0.5-10 g L-1 ZVI), respectively. The results showed that Se(VI) removal significantly decreased with increasing ionic strength, while As(V) removal showed little variation. Common competing anions (nitrate, bicarbonate, silicate, and phosphate), present in shallow groundwater and stormwater, caused marginal Se(VI) desorption (2.42 +/- 0.13%) and undetectable As(V) desorption from ZVI. The competition between As(V) and Se(VI) for ZVI removal depended on the initial molar ratio and surface sites, which occurred when the Se(VI) concentration was higher than the As(V) concentration in this study. The characterization of As(V)- and Se(VI)-loaded ZVI by X-ray diffraction and Raman analysis revealed that ZVI gradually converted to magnetite/maghemite corrosion products with lepidocrocite in flowback water over 30 days. Similar corrosion compositions were confirmed in aerobic and anaerobic conditions regardless of the molar ratio of As(V) to Se(VI). The high reactivity and stability of ZVI showed its suitability for in-situ prevention of As(V) and Se(VI) migration due to accidental leakage, spillage, or overflow of flowback water. PMID- 27718429 TI - The role of Cu(II) in the reduction of N-nitrosodimethylamine with iron and zinc. AB - The role of Cu(II) in the reduction of N-nitrosodimethylamine (NDMA) with zero valent metals was investigated by determining the effects of Cu(II) on the removal, kinetics, products, and mechanism. NDMA removal was enhanced, and all reactions followed a pseudo-first-order kinetic model except for the Fe and Fe/0.1 mM Cu(II) systems. The iron mass-normalized pseudo-first-order rate constants (kMFe) increased with the Cu(II) concentration. The zinc mass normalized pseudo-first-order rate constants (kMZn) were identical to those with the Cu(II) concentrations from 0.1 mM to 1.0 mM and were higher with 2.0 mM Cu(II). The types of products detected were unchanged. Some unknown products were also found. NDMA was reduced to 1,1-dimethylhydrazine (unsymmetrical dimethylhydrazine, UDMH). Then, UDMH was reduced into dimethylamine (DMA) by the Fe/Cu(II) and Zn/Cu(II) systems. Catalytic hydrogenation was proposed as the reduction mechanism. Several copper species, such as Cu(OH)2 in the Fe/Cu(II) system and Cu2O and Cu(OH)2 in the Zn/Cu(II) system enhanced NDMA reduction. Differences between the Fe/Cu(II) and Zn/Cu(II) systems were caused by the reduction potentials and surface conditions of the different metals and the copper species in the various systems. PMID- 27718430 TI - Alkyl bicarbamates supramolecular organogelators with effective selective gelation and high oil recovery from oil/water mixtures. AB - A series of alkyl bicarbamates supramolecular organogelators were synthesized with different structures and lengths of alkyl chains. The driving forces for the self-assembly of small molecules, including the intermolecular H bonding, pi-pi stacking and van der Waals interactions, played an important role in the formation of different 3D network structures, i.e., fibers, ribbons, sheets, and prisms. And a probable formation process of the gel networks was proposed. Furthermore, the phase-selective gelling performances were investigated for oil removal from aqueous solution. Interestingly, the gelling properties were found to be affected by the length and structure of alkyl chains, while some gelators with intermediate alkyl chain lengths could effectively gel all the tested oils from water surface within 15 min, such as Russian crude oil, diesel, gasoline, soybean oil, peanut oil, olive oil, cyclohexane, hexane and ethyl acetate. Advantageously, fast gelation, high rate of oil removal (>95%) and excellent oil retention rate (close to 100%) were realized in the recovery of oil spills from water surface. This kind of supramolecular gelators demonstrates good potential applications in the delivery or removal of organic pollution from oil/water mixtures. PMID- 27718431 TI - IL-2 and polyoma BK virus infection; A systematic review article. AB - It has been demonstrated that IL-2 plays a dual role in induction/suppression of immune responses via activation of conventional and regulatory T lymphocytes, respectively. IL-2 contacts complete IL-2 receptor (IL-2R) which contains CD25 (alpha chain) on the antigen specific activated T helper and cytotoxic lymphocytes and also T regulatory cells. Additionally, previous investigations revealed that polyoma BK virus (PBK) reactivation and induction of PBK associated nephropathy (PBKAN) is a main complication following renal transplantation. Based on the important dual roles played by IL-2 in the immune responses, it may be hypothesized that IL-2/IL-2R interaction could be considered a potential mechanism against/toward PBK reactivation and also PBKAN. Accordingly, the aim of the current review article is to determine the roles of IL-2 IL-2/IL-2R interaction in PBK reactivation and PBKAN complications. PMID- 27718432 TI - Sarcomatoid carcinoma of the jejunum with gastric metastases: A case report and review of the literature. AB - INTRODUCTION: Sarcomatoid carcinoma (SCA) of jejunum is an extremely rare condition. To our knowledge, only 17 cases have been reported in the literature. PRESENTATION: We introduced an additional case of the sarcomatoid carcinoma of jejunum in a 62-year-old Chinese male who presented with epigastric pain for 3 weeks. Multiple tumors originated in the jejunum and metastases to mesentery lymph nodes and distal stomach were found during the laparotomy. The patient underwent palliative resection of the tumors. He died 11 days after the operation. DISCUSSION: Sarcomatoid carcinoma (SCA) of jejunum is an extremely poor prognostic tumor in human being. The diagnosis of SCA was based on pathological observations and immunohistochemical staining. There is no official treatment guideline for SCA, but wide excision including the tumor is the main goal of treatment. CONCLUSION: This is the first case of sarcomatoid carcinoma of jejunum with gastric metastases being reported and also the shortest survival period after the operation. Surgery is the cornerstones of treatment but the ideal means is still unknown due to the short survival and inadequate reports. PMID- 27718433 TI - Liver Angiosarcoma: Rare tumour associated with a poor prognosis, literature review and case report. AB - INTRODUCTION: Liver angiosarcoma is a very uncommon tumour of mesenchymal origin, representing between 0.1-2% of all primary tumours of the liver, affecting mainly men in their sixth or seventh decade of life, with a high mortality in the first years (Chaudhary et al., 2015). Literature reports of its surgical treatment vary from a total or partial hepatectomy with or without liver transplant. PRESENTATION OF CASE: A 37year old male, with a 7year history of a fatty liver, was found to have a 12cm diameter tumour in a cirrhotic liver, during an abdominal Computed Tomography (CT) scan. Patient was asymptomatic with negative tumour markers, yet tumour liver biopsy revealed a Liver Angiosarcoma with positive immunohistochemistry for neoplastic cells CD31 and CD34. Patient was deemed candidate for a partial hepatectomy of the affected liver segments which was done without complications and no evidence of other tumour lesions was found during surgery. Patient continued oncologic management with ongoing chemotherapy. DISCUSION: Liver Angiosarcoma, although rare, persists with a high mortality due to its aggressive nature. Never the less liver transplantation, although proven to be an effective treatment for many pathologies that culminate in liver failure, fails to improve patients' survival and prognosis, when compared to partial hepatectomy as surgical management to for liver Angiosarcoma, CONCLUSION: Partial hepatectomy as surgical management, followed by adjuvant therapy, for Liver Angiosarcoma continues to prove favourable results and prognosis compared to Liver Transplantation. PMID- 27718434 TI - Laparoscopic totally extra-peritoneal hernia repair for bilateral Spigelian hernias and coincident inguinal hernia: A case report. AB - INTRODUCTION: Spigelian hernia (SH) is a rare ventral hernia occurring near the lateral border of the rectus muscle. The treatment remains controversial and depends on institutional expertise. Although laparoscopic surgery is a good adaptation for the repair of ventral hernias, only a few cases have been reported in the literature. Here, we report a case of totally extra-peritoneal (TEP) repair for bilateral SHs. PRESENTATION OF CASE: A 74-year-old Japanese man presented with asymptomatic bulges in the right lower abdominal quadrant. On physical examination, the bulges were located to the right of the lateral border of the abdominal rectus muscle and the right inguinal region in an upright position. We diagnosed right SH and coincident homonymous ipsilateral inguinal hernia (IH) by abdominal computed tomography and planned a curative operation by laparoscopy. By first laparoscopic exploration, we found an asymptomatic SH to the left of the lateral border of the abdominal rectus muscle and performed TEP repair for all hernias. The second laparoscopic exploration after fixing the mesh in place revealed that the orifice of the right SH was scarred and stiffened by repeated prolapse. We finally eliminated the sac by ligation because of a fear causing of reduction en masse of the SH. DISCUSSION AND CONCLUSION: The use of laparoscopy simplified the diagnosis and facilitates the subsequent repair of the hernia. TEP approach is the ideal treatment for the simultaneous laparoscopic repair of SH and IH. PMID- 27718435 TI - Suspected total spinal in patient having emergent Caesarean section, a case report and literature review. AB - INTRODUCTION: Epidural analgesia is commonly used for management of pain during childbirth. Need for emergent Caesarean section e.g. because of signs of foetal distress or lack of progress is however not an uncommon event. In females having an established epidural; general anaesthesia, top-up of the epidural or putting a spinal are all possible options. Dosing of the spinal anaesthesia in females having epidural is a matter of discussion. PRESENTATION OF CASE: We describe a healthy 32 years, 0 para mother in gestation week 36 having labour epidural analgesia but due to foetal distress scheduled for an emergent Caesarean section category 2 that developed upper extremity weakness and respiratory depression after administration of standard dose high density bupivacaine/morphine/fentanyl intrathecal anaesthesia. She was emergent intubated and resumed motor function after 15-20min. DISCUSSION: A too extensive cephalic spread was the most plausible explanation to the event. Whether or not reducing the dose for a spinal anaesthesia in mothers having an established labour epidural analgesia is a matter of discussion. It is of course of importance to achieve a rapid and effective surgical anaesthesia but also avoiding overdosing with the risk for a too high cephalic spread. CONCLUIOSN: To perform spinal anaesthesia for emergent Caesarean in patients having an epidural for labour pain is a feasible option and should be considered in category 2-3 section. The dose for a convert spinal block should be assessed on an individual basis and reasonably reduced. PMID- 27718436 TI - Management of aggressive giant cell tumor of calcaneal bone: A case report. AB - INTRODUCTION: Prevalence of giant cell tumor (GCT) at atypical locations like bones of the feet are rare, seen in <1% of cases. GCT may have aggressive features, including cortical expansion or destruction with a soft-tissue component. Difficult diagnosis most often followed with complicated management and high recurrence rate remains a challenge that is rarely reported. PRESENTATION OF CASE: We presented a case of forty-six-year-old male patient with giant cell tumor of the right calcaneus Campanacci 3 with secondary aneurysmal bone cyst (ABC). Wide excision total calcaneoctomy, followed by reconstruction bone defect using femoral head allograft and soft tissue coverage with sural flap had been done. DISCUSSION: Conservative surgery with careful curettage and placement of bone cement should be considered the treatment of choice when feasible. However, aggressive GCTs may require wide excision and reconstruction or may be amputation. We decided to do salvage surgery since: traditionally curettage is not possible, adequately wide resection of local tumor could be achieved, neurovascular bundle was not involved, and also bone and soft tissue reconstructions could be done. In addition, he refused for amputation. CONCLUSION: Wide excision total calcaneoctomy, bone allograft reconstruction and soft tissue coverage with sural flap is a good option for surgical management in aggressive GCT of calcaneus instead of amputation. PMID- 27718437 TI - Extreme oncoplastic breast surgery: A case report. AB - INTRODUCTION: So called "extreme oncoplastic surgery" is emerging as a new promising concept in breast cancer surgery allowing successful breast conservation in selected patients with multicentric tumors. PRESENTATION OF CASE: We report the case of a 48-year-old woman presenting with a multicentric breast cancer and successfully treated with an oncoplastic technique consisting in three radical lumpectomies followed by breast reshaping and simultaneous contralateral symmetrization. DISCUSSION: According to our experience, oncoplastic conserving breast surgery could represent a better option than the combination of mastectomy, reconstruction and radiation therapy, in terms of quality of life for selected patients affected by multicentric breast cancer. CONCLUSION: The surgical treatment for multicentric breast cancers remains controversial even though emerging evidences show good oncological and aesthetic outcomes following oncoplastic conserving breast surgery. PMID- 27718438 TI - Urological injuries associated with pelvic fractures: A case report of a detached bone segment inside the bladder. AB - INTRODUCTION: Urological injuries in pelvic fractures are noticed in 6-15% of the cases. The bladder, due to its anatomical position, is prone to rupture in pelvic fractures. The majority of urinary bladder injuries are either extraperitoneal or intraperitoneal. Nonetheless, both types can occur simultaneously in 6% of the cases. PRESENTATION OF THE CASE: A 45-year-old male was brought to our emergency department after being struck by an automobile. In the absence of signs of urethral injury, a Foley's catheter was inserted revealing gross hematuria. The radiological assessment showed bilateral non-displacement sacral wing fractures, bilateral non-displacement anterior column fractures and bilateral comminuted superior and inferior pubic rami fractures, with a detached pubic bone fragment displaced posteriorly. A CT cystogram was performed showing intraperitoneal and extraperitoneal extravasation of contrast. The patient was taken to surgery. A sharp-edged bony fragment was discovered inside the bladder. A two-layer closure of the bladder was performed. DISCUSSION: Pelvic fractures with concomitant lower urinary tract injuries are associated with high morbidity and mortality. The signs indicative of bladder rupture include a more than one centimeter diastasis of the symphysis pubis and a displaced fracture of more than one centimeter involving the obturator ring. However, the signs may not be present as in our case. CONCLUSION: This unusual case illustrates the potential risk of bladder injury following stable pelvic fractures through a detached bone segment. It also emphasizes on having a high index of suspicion. The teamwork and multidisciplinary approach are essential for an optimal outcome. PMID- 27718439 TI - Case report of cadaveric kidney transplantation with renal-portal venous drainage: A feasible way for a venous drainage in a complex generalized thrombosed vessels setting. AB - INTRODUCTION: One of the frequent complications suffered by patients with chronic renal failure is the lack of vascular access due to venous thrombosis. This means that the transplant surgeon must have a detailed knowledge of the intra-abdominal venous system, and other alternative surgeries, at the time of performing the renal graft implant, in order to ensure a good venous drainage. PRESENTATION OF THE CASE: This article provides a case report regarding a patient with no vascular access and with surgical difficulties at the time of the kidney transplant, in whom a renal-portal venous drainage was performed with very good outcome. DISCUSION: Renal-portal venous drainage is a way to performe kidney transplant with good outcome. In Fundacion Valle del Lili we have overcome the lack of vascular access in patients that need a renal transplant by new surgical technics that improve the patients quality of life and survival. CONCLUSION: We can conclude that new surgical alternatives exist for those patients with chronic renal failure that have no vascular access. These patients are a priority for kidney transplants and the surgeon must take in to account the need for a new surgical assessment. PMID- 27718440 TI - An interesting case report of vertebral artery dissection following polytrauma. AB - INTRODUCTION: The authors present an interesting case of a 19-year-old male who presented as a polytrauma patient following a fall from a height. PRESENTATION OF CASE: He was initially managed on the intensive care unit with intracranial pressure bolt monitoring after being intubated and sedated and having his other traumatic injuries stabilized. Upon attempting to wean sedation and extubation a repeat CT scan of the head was undertaken and showed a new area suggested of cerebral infarction, this was a new finding. Further imaging found that he had a cervical vertebral artery dissection following this polytrauma mode of injury. DISCUSSION: The incidence of vertebral artery dissection following generalized or local trauma is rising but routine imaging/screening in these patients is not undertaken. CONCLUSION: Our report displays select images related to this case report and emphasizes the consideration of routine imaging in head and neck traumatic injuries to diagnose internal carotid and/or vertebral artery dissections much earlier. PMID- 27718441 TI - Promising in vitro and in vivo inhibition of multidrug-resistant Helicobacter pylori by linezolid and novel oxazolidinone analogues. AB - The objective of this study was to investigate the prevalence of drug-resistant Helicobacter pylori in Beijing Tian Tan Hospital (Beijing, China) and to determine the susceptibility of H. pylori to linezolid and novel oxazolidinone analogues. Minimum inhibitory concentrations (MICs) of amoxicillin, clarithromycin, metronidazole, ciprofloxacin, tetracycline and levofloxacin against H. pylori were determined by Etest. The in vitro antibacterial activities of linezolid and novel oxazolidinone analogues were assessed by the disk diffusion method. In vivo antibacterial activities were determined by intragastric administration and stomach CFU counting. Drug resistance patterns were serious among clinical H. pylori isolates, with a rate of multidrug resistant H. pylori of 10.1%. Linezolid was observed to exhibit in vitro activity, with MICs ranging from <=0.25mg/L to 32mg/L against clinical H. pylori isolates (MIC50, 2mg/L; MIC90, 8mg/L). The oxazolidinone analogue sy142 demonstrated better antimicrobial activity than linezolid in vitro. These results indicate that oxazolidinones may be appropriate agents to treat drug-resistant H. pylori. Further clinical trials should be performed to confirm this.

AB - BACKGROUND: Prognostic biomarkers are needed to improve the management of the heart failure (HF) epidemic, being the brain natriuretic peptides the most valuable. Here we evaluate 3 biomarkers, high sensitivity troponin T (hs-TnT), galectin-3 (Gal-3) and C-terminal propeptide of type I procollagen (CICP), compare them with a recently described new candidate (sAXL), and analyze their relationship with BNP. METHODS: HF patients with reduced ejection fraction (n=192) were included in this prospective observational study, with measurements of candidate biomarkers, functional, clinical and echocardiographic variables. A Cox regression model was used to determine predictors for clinical events, i.e. all-cause mortality and heart transplantation. RESULTS: Hs-TnT circulating values were correlated to clinical characteristics indicative of more advanced HF. When analyzing the event-free survival at a mean follow-up of 3.6years, patients in the higher quartile of either BNP, hs-TnT, CICP and sAXL had increased risk of suffering a clinical event, but not Gal-3. Combination of high sAXL and BNP values had greater predictive value (HR 6.8) than high BNP alone (HR 4.9). In a multivariate Cox regression analysis, BNP, sAXL and NYHA class were independent risk factors for clinical events. CONCLUSIONS: In this HF cohort, hs-TnT is a good HF marker and has a very significant prognostic value. The prognostic value of CICP and sAXL was of less significance. However, hs-TnT did not add predictive value to BNP, while sAXL did. This suggests that elevated troponin has a common origin with BNP, while sAXL could represent an independent pathological mechanism.

AB - BACKGROUND: The increasing use of conducted electronic weapons (CEW) cause concern regarding its secure application, specially regarding the implications in the cardiovascular system. METHODS: The objective was to determine Spark CEW safety through cardiovascular parameters analysis of healthy volunteers subjected to its use. RESULTS: Volunteers over 18years without cardiovascular disease or recent use of illegal drugs were submitted, before and after being affected with Spark CEW, to clinical evaluation; blood collection for serum laboratory tests; transthoracic electrocardiography at rest, transthoracic echodopplercardiogram and 24hour Holter. RESULTS: All 71 patients reported being incapable of any voluntary reaction during the shock of the application time. No arrhythmia or myocardial necrosis was related to the use of non-lethal weapon SPARK. Reported adverse events were self-limited, and mostly mild. CONCLUSIONS: SPARK brand CEW is effective in incapacitating individuals by the shock of the application time, without causing. PMID- 27718446 TI - Catheter-directed treatment for acute pulmonary embolism: Systematic review and single-arm meta-analyses. AB - BACKGROUND: We sought to estimate the efficacy and safety outcomes of catheter directed treatment (CDT) for patients with acute pulmonary embolism (PE). METHODS: We searched SCOPUS for studies reporting outcomes after CDT for acute PE. Studies were categorized in three groups for analyses due to heterogeneity in the classification of acute PE: 1) patients with PE causing right ventricular dysfunction and haemodynamic instability: unstable haemodynamic status, 2) patients with PE causing right ventricular dysfunction where study outcomes were not stratified by haemodynamic status: stable and unstable haemodynamic status, and 3) patients with PE causing right ventricular dysfunction who remained haemodynamically stable: stable haemodynamic status. Efficacy and safety outcomes were estimated and presented as point estimates with 95% confidence intervals. RESULTS: In 35 studies with 1253 patients, 1277 CDTs were performed. The in hospital mortality rates for the unstable haemodynamic status, stable and unstable haemodynamic status, and stable haemodynamic status groups were 18.1% (7.3-38.2%), 7.1% (5.0-10.1%), and 2.6% (0.8-7.3%), respectively. The major bleeding rates across the groups were estimated to be 4.5, 8.5 and 3.9 per 100 CDTs, respectively. Minor bleeding occurred in 6.2, 11.9 and 9.1 per 100 CDTs, respectively. After CDT, all groups had improvements in mean pulmonary artery pressure and right ventricular function. CONCLUSIONS: We provide descriptive measures of efficacy and safety for patients who underwent CDT for acute PE. PMID- 27718447 TI - Targeting B cells in treatment of autoimmunity. AB - B cells have emerged as effective targets for therapeutic intervention in autoimmunities in which the ultimate effectors are antibodies, as well as those in which T cells are primary drivers of inflammation. Proof of this principle has come primarily from studies of the efficacy of Rituximab, an anti-CD20 mAb that depletes B cells, in various autoimmune settings. These successes have inspired efforts to develop more effective anti-CD20s tailored for specific needs, as well as biologicals and small molecules that suppress B cell function without the risks inherent in B cell depletion. Here we review the current status of B cell targeted therapies for autoimmunity. PMID- 27718448 TI - Endoplasmic reticulum stress in beta cells and autoimmune diabetes. AB - Type 1 diabetes results from the autoimmune destruction of pancreatic beta cells, leading to insulin deficiency and hyperglycemia. Although multiple attempts have been made to slow the autoimmune process using immunosuppressive or immunomodulatory agents, there are still no effective treatments that can delay or reverse the progression of type 1 diabetes in humans. Recent studies support endoplasmic reticulum (ER) as a novel target for preventing the initiation of the autoimmune reaction, propagation of inflammation, and beta cell death in type 1 diabetes. This review highlights recent findings on ER stress in beta cells and development of type 1 diabetes and introduces potential new treatments targeting the ER to combat this disorder. PMID- 27718449 TI - AMECM/DCB scaffold prompts successful total meniscus reconstruction in a rabbit total meniscectomy model. AB - Tissue-engineered meniscus regeneration is a very promising treatment strategy for meniscus lesions. However, generating the scaffold presents a huge challenge for meniscus engineering as this has to meet particular biomechanical and biocompatibility requirements. In this study, we utilized acellular meniscus extracellular matrix (AMECM) and demineralized cancellous bone (DCB) to construct three different types of three-dimensional porous meniscus scaffold: AMECM, DCB, and AMECM/DCB, respectively. We tested the scaffolds' physicochemical characteristics and observed their interactions with meniscus fibrochondrocytes to evaluate their cytocompatibility. We implanted the three different types of scaffold into the medial knee menisci of New Zealand rabbits that had undergone total meniscectomy; negative control rabbits received no implants. The reconstructed menisci and corresponding femoral condyle and tibial plateau cartilage were all evaluated at 3 and 6 months (n = 8). The in vitro study demonstrated that the AMECM/DCB scaffold had the most suitable biomechanical properties, as this produced the greatest compressive and tensile strength scores. The AMECM/DCB and AMECM scaffolds facilitated fibrochondrocyte proliferation and the secretion of collagen and glycosaminoglycans (GAGs) more effectively than did the DCB scaffold. The in vivo experiments demonstrated that both the AMECM/DCB and DCB groups had generated neomeniscus at both 3 and 6 months post-implantation, but there was no obvious meniscus regeneration in the AMECM or control groups, so the neomeniscus analysis could not perform on AMECM and control group. At both 3 and 6 months, histological scores were better for regenerated menisci in the AMECM/DCB than in the DCB group, and significantly better for articular cartilage in the AMECM/DCB group compared with the other three groups. Knee MRI scores (Whole-Organ Magnetic Resonance Imaging Scores (WORMS)) were better in the AMECM/DCB group than in the other three groups at both 3 and 6 months. At both 3 and 6 months, RT-PCR demonstrated that aggrecan, Sox9, and collagen II content was significantly higher, and mechanical testing demonstrated greater tensile strength, in the AMECM/DCB group neomenisci compared with the DCB group. PMID- 27718450 TI - Interaction of imatinib mesylate with human serum transferrin: The comparative spectroscopic studies. AB - Imatinib mesylate (Imt) is a tyrosine kinase inhibitor mainly used in the treatment of Philadelphia chromosome-positive chronic myelogenous leukemia (Ph+CML). Human serum transferrin is the most abundant serum protein responsible for the transport of iron ions and many endogenous and exogenous ligands. In this study the mechanism of interactions between the imatinib mesylate and all states of transferrin (apo-Tf, Htf and holo-Tf) has been investigated by fluorescence, ultraviolet-visible (UV-vis), circular dichroism (CD) and zeta potential spectroscopic methods. Based on the experimental results it was proved that under physiological conditions the imatinib mesylate binds to the each form of transferrin with a binding constant c.a. 105M-1. The thermodynamic parameters indicate that hydrogen bonds and van der Waals were involved in the interaction of apo-Tf with the drug and hydrophobic and ionic strength participate in the reaction of Htf and holo-Tf with imatinib mesylate. Moreover, it was shown that common metal ions, Zn2+ and Ca2+ strongly influenced apo-Tf-Imt binding constant. The CD studies showed that there are no conformational changes in the secondary structure of the proteins. No significant changes in secondary structure of the proteins upon binding with the drug and instability of apo-Tf-Imt system are the desirable effects from pharmacological point of view. PMID- 27718451 TI - Hyperspectral Raman imaging of human prostatic cells: An attempt to differentiate normal and malignant cell lines by univariate and multivariate data analysis. AB - Hyperspectral Raman images of human prostatic cells have been collected and analysed with several approaches to reveal differences among normal and tumor cell lines. The objective of the study was to test the potential of different chemometric methods in providing diagnostic responses. We focused our analysis on the nu(CH) region (2800-3100cm-1) owing to its optimal Signal-to-Noise ratio and because the main differences between the spectra of the two cell lines were observed in this frequency range. Multivariate analysis identified two principal components, which were positively recognized as due to the protein and the lipid fractions, respectively. The tumor cells exhibited a modified distribution of the cytoplasmatic lipid fraction (mainly localized alongside the cell boundary) which may result very useful for a preliminary screening. Principal Component analysis was found to provide high contrast and to be well suited for image-processing purposes. Self-Modelling Curve Resolution made available meaningful spectra and relative-concentration values; it revealed a 97% increase of the lipid fraction in the tumor cell with respect to the control. Finally, a univariate approach confirmed significant and reproducible differences between normal and tumor cells. PMID- 27718452 TI - A post-decoding re-ranking algorithm for predicting interacting residues in proteins with hidden Markov models incorporating long-distance information. AB - Protein-protein interactions play a central role in the biological processes of cells. Accurate prediction of the interacting residues in protein-protein interactions enhances understanding of the interaction mechanisms and enables in silico mutagenesis, which can help facilitate drug design and deepen our understanding of the inner workings of cells. Correlations have been found among interacting residues as a result of selection pressure to retain the interaction during evolution. In previous work, incorporation of such correlations in the interaction profile hidden Markov models with a special decoding algorithm (ETB Viterbi) has led to improvement in prediction accuracy. In this work, we first demonstrated the sub-optimality of the ETB-Viterbi algorithm, and then reformulated the optimality of decoding paths to include correlations between interacting residues. To identify optimal decoding paths, we propose a post decoding re-ranking algorithm based on a genetic algorithm with simulated annealing and show that the new method gains an increase of near 14% in prediction accuracy over the ETB-Viterbi algorithm. PMID- 27718453 TI - Parental reflective functioning among mothers with eating disorder symptomatology. AB - OBJECTIVE: Reflective Functioning is a vital aspect of parental aptitude and its absence, especially in the presence of psychopathology, can impair attachment. This study sought to clarify the relationship of parental RF among mothers with eating disorder symptomatology. METHOD: We assessed 59 mothers for ED symptomatology using the Eating Disorder Examination Questionnaire (EDE-Q) and RF through the Parental Reflective Functioning Questionnaire (PRFQ). Bivariate and multivariate analyses compared PRFQ subscales between symptomatic and asymptomatic mothers, using a clinical cutoff score of 4 on the EDE-Q subscales. RESULTS: Greater weight and shape concerns were found to significantly predict higher RF (p=0.023; p=0.026). DISCUSSION: This finding could indicate a similar pattern seen among individuals with bulimia nervosa; individuals have higher RF scores, although affect regulation may still be limited. More research is needed with a larger sample to define the relationship between ED symptomatology and RF and identify potential mediators and moderators. PMID- 27718454 TI - Association of binge eating behavior and psychiatric comorbidity in ELSA-Brasil study: Results from baseline data. AB - OBJECTIVE: To estimate the association of binge eating behavior (BE) with common mental disorders (CMD). METHOD: Cross sectional investigation of 14,088 adults, aged 35-74years (ELSA-Brasil study). BE was assessed with Structured Clinical Interview for DSM Disorders (SCID - DSM IV) questions, and psychiatric morbidity with CIS-R (CIS R - Clinical Interview Schedule Revised). Poisson regression was used to estimate the association of BE and psychiatric morbidity. RESULTS: Adjusted prevalence ratios (PR) for CMD and BE were: PR=1.60 (1.34-1.91) for a CIS R score 12-18 (presence of CMD with lower clinical severity); PR=2.40 (2.06 2.80) for a CIS R score>=18 (severe symptom profile likely to require treatment); for psychiatric diagnoses: PR=2.24 (1.84-2.73) for depressive episodes; PR=1.77 (1.53-2.04) for anxiety disorders, and PR=1.42 (1.20-1.67) for mixed depressive anxiety disorder. CONCLUSION: BE was associated with higher prevalence of common mental disorders. Our findings highlight the need to investigate mechanisms involved in the relationship of BE, obesity and psychopathology in low/middle income countries. PMID- 27718455 TI - Molecular mechanisms in compatibility and mechanical properties of Polyacrylamide/Polyvinyl alcohol blends. AB - The objectives of this study were to develop a computational model based on molecular dynamics technique to investigate the compatibility and mechanical properties of Polyacrylamide (PAM)/Polyvinyl alcohol (PVA) blends. Five simulation models of PAM/PVA with different composition ratios (4/0, 3/1, 2/2, 1/3, 0/4) were constructed and simulated by using molecular dynamics (MD) simulation. The interaction mechanisms of molecular chains in PAM/PVA blend system were elaborated from the aspects of the compatibility, mechanical properties, binding energy and pair correlation function, respectively. The computed values of solubility parameters for PAM and PVA indicate PAM has a good miscibility with PVA. The results of the static mechanical analysis, based on the equilibrium structures of blends with differing component ratios, shows us that the elastic coefficient, engineering modulus, and ductility are increased with the addition of PVA content, which is 4/0 PAM/PVA<3/1 PAM/PVA<2/2 PAM/PVA<1/3 PAM/PVA<0/4 PAM/PVA. Moreover, binding energy results indicate that a stronger interaction exists among PVA molecular chains comparing with PAM molecular chains, which is why the mechanical properties of blend system increasing with the addition of PVA content. Finally, the results of pair correlation functions (PCFs) between polar functional groups and its surrounding hydrogen atoms, indicated they interact with each other mainly by hydrogen bonds, and the strength of three types of polar functional groups has the order of O(-OH)>O( C=O)>N(-NH2). This further elaborates the root reason why the mechanical properties of blend system increase with the addition of PVA content. PMID- 27718456 TI - Validation of the Seven Up Seven Down Inventory in bipolar offspring: screening and prediction of mood disorders. Findings from the Dutch Bipolar Offspring Study. AB - OBJECTIVE: To validate the Seven Up Seven Down (7U7D), an abbreviated version of the General Behavior Inventory (GBI), as screener for mood disorders and test its ability to predict mood disorders over time in individuals at risk for bipolar disorder (BD). METHODS: Bipolar offspring (n=108) were followed from adolescence into adulthood and assessed at baseline, 1-, 5- and 12 years follow-up (T1-T4 respectively). Offspring were assessed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children--Present and Lifetime Version, Structured Clinical Interview for DSM-IV Axis I Disorders and the GBI. RESULTS: Performance of the GBI and 7U7D was functionally similar for the depression (7D) scale, but variable for the mania (7U) scale. As screener for mood disorders (T4), the 7D showed fair diagnostic efficiency (area under the curve (AUC) 0.68, p<0.01, OR 1.53, 95% CI 1.15-2.03). The discriminative validity for BD and unipolar disorder was only close to significant (7D AUC 0.66, p=0.078; 7U AUC 0.67, p=0.067). In terms of prediction of mood disorder onset between T1 and T4, the 7D, but not the 7U, was associated with new onset (AUC 0.67, p<0.05; HR 1.14, 95% CI 1.07-1.23). The 7U7D did not achieve significant prediction of BD. LIMITATIONS: Relative small sample size and limited generalizability. CONCLUSIONS: Based on the current study, the 7U7D shows limited potential as screening instrument for mood disorders in bipolar offspring. The clinical utility of the 7U7D needs further exploration for use in clinical and research settings. PMID- 27718457 TI - Nuclear export signal of PRRSV NSP1alpha is necessary for type I IFN inhibition. AB - The nonstructural protein 1alpha (NSP1alpha) of porcine reproductive and respiratory syndrome virus (PRRSV) is a nucleo-cytoplasmic protein that suppresses the production of type I interferon (IFN). In this study, we investigated the relationship between the subcellular distribution of NSP1alpha and its inhibition of type I IFN. NSP1alpha was found to contain the classical nuclear export signal (NES) and NSP1alpha nuclear export was CRM-1-mediated. NSP1alpha was shuttling between the nucleus and cytoplasm. We also showed that the nuclear export of NSP1alpha was necessary for its ability for type I IFN inhibition. NSP1alpha was also found to interact with CBP, which implies a possible mechanism of CBP degradation by NSP1alpha. Taken together, our results describe a novel mechanism of PRRSV NSP1alpha for type I IFN inhibition and suppression of the host innate antiviral response. PMID- 27718459 TI - DIADECOMP: A new approach to analyze decompositions from projection spectroscopy. AB - We demonstrate for the first time a complete small protein characterization with the projection-decomposition approach, including full assignments as well as determination of the 3D fold. In TOCSY- and NOESY-type 4D experiments, pairing of signals from hydrogens and from their respective heavy atoms in decompositions represents a new problem. An approach, referred to as "DIADECOMP" (diagonal decomposition), is introduced to solve this problem; it consists of two separate decompositions of the input projections, differing in a 45 degrees rotation of the spectral axes. While DIADECOMP requires a somewhat complex formulation, in practice it results in observing signals in the rotated decompositions that correspond to sums or differences of frequencies. When applied to a small protein, human defensin beta6, the analysis of a HCC(CO)NH-TOCSY with DIADECOMP results in largely unambiguous assignments of the aliphatic side chain groups. Furthermore, DIADECOMP applied to a 15N-HSQC-NOESY-15N-HSQC provides all expected short distances between amide groups (defined as all HN-HN distances <3.5A in a reference structure). It is worth noting that short HN-HN distances unambiguously define alpha-helices, the alignment of beta-strands in sheets, as well as the presence of beta-bulges. This approach of using a minimal amount of NMR data, namely four projection experiments recorded in ~2.5days, resulted for the human defensin beta6 in complete assignments and a backbone fold with a RMSD of the non flexible structure of 0.6A. Uniqueness of decompositions specifically from TOCSY- and NOESY-type 4D experiments is discussed. PMID- 27718458 TI - Health-related quality of life assessment in contemporary phase III trials in advanced colorectal cancer. AB - BACKGROUND: Health-related quality of life (HRQOL) is often used as an endpoint in cancer clinical trials. We assessed the frequency and correlates of HRQOL use in phase III trials in advanced colorectal cancer. METHODS: We searched PubMed for phase III trials published between January 1998 and December 2014, as well as for companion papers reporting on HRQOL separately. We excluded papers reporting on correlative biology or prognostic factors in isolation from the main trial results, as well as trials on supportive care and on local therapy. RESULTS: We retrieved 111 trials that enrolled a total of 61,531 patients in 241 trial arms. HRQOL was reportedly used as an endpoint in 40 trials (36%), in all but two as a secondary endpoint. There was a significant decrease in the use of HRQOL, with frequencies of 46% in trials published between 1998 and 2006, and 27% between 2007 and 2014 (P=0.04). Trials with HRQOL as endpoint were significantly larger than trials without such endpoint. Formal statistical comparisons involving HRQOL parameters were reported in 36 of 40 trials (90%) with HRQOL assessment, with a significant difference between arms found in 14 (39%), six of which favoring the experimental arm. HRQOL gains were usually accompanied by improvements in efficacy endpoints, but were not related to the number of patients or chemotherapy line. CONCLUSIONS: HRQOL has been formally assessed in about one third of recent phase III trials in advanced colorectal cancer, with a significant gain in HRQOL in about 40% of cases. It is questionable whether HRQOL results may largely help select between competing treatments. This assumption may be one of the reasons for the apparent decreased use of HRQOL as an endpoint in phase III trials in this disease. PMID- 27718460 TI - Sculpting 3D spatial selectivity with pairs of 2D pulses: A comparison of methods. AB - Enhancing the specificity of the spins' excitation can improve the capabilities of magnetic resonance. Exciting voxels with tailored 3D shapes reduces partial volume effects and enhances contrast, particularly in cases where cubic voxels or other simple geometries do not provide an optimal localization. Spatial excitation profiles of arbitrary shapes can be implemented using so-called multidimensional RF pulses, which are often limited in practice to 2D implementations owing to their sensitivity to field inhomogeneities. Recent work has shown the potential of spatio-temporally encoded (SPEN) pulses towards alleviating these constraints. In particular, 2D pulses operating in a so-called hybrid scheme where the "low-bandwidth" spatial dimension is sculpted by a SPEN strategy while an orthogonal axis is shaped by regular k-space encoding, have been shown resilient to chemical shift and B0 field inhomogeneities. In this work we explore the use of pairs of 2D pulses, with one of these addressing geometries in the x-y plane and the other in the x-z dimension, to sculpt complex 3D volumes in phantoms and in vivo. To overcome limitations caused by the RF discretization demanded by these 2D pulses, a number of "unfolding" techniques yielding images from the centerband RF excitation while deleting sideband contributions - even in cases where center- and side-bands severely overlap - were developed. Thus it was possible to increase the gradient strengths applied along the low bandwidth dimensions, significantly improving the robustness of this kind of 3D sculpting pulses. Comparisons against conventional pulses designed on the basis of pure k space trajectories, are presented. PMID- 27718461 TI - Iptakalim induces mitochondria-dependent apoptosis in hypoxic rat pulmonary arterial smooth muscle cells. AB - OBJECTIVES: Pulmonary vascular medial hypertrophy in hypoxic pulmonary arterial hypertension (HPH) is caused in part by decreased apoptosis in pulmonary artery smooth muscle cells (PASMCs). Iptakalim (Ipt), an ATP sensitive potassium channel opener, ameliorates HPH in animal models. Here we investigated the effects of Ipt on proliferation and apoptosis of hypoxic rat PASMCs, and to determine the possible underlying mechanisms. METHODS: Primary rat PASMCs were isolated and cultured. PASMCs were cultured for 24h in normoxia or hypoxia (5% O2) conditions with and without Ipt. Cell proliferation and cycle were determined by MTT assay and flow cytometry, respectively. Mitochondrial membrane potential (Deltaym) was detected by fluorescence microscope Western blot assays were used to examine the expression of cyclin D, CDK4, endothelin-1 (ET-1), hypoxia-inducible factor-1 (HIF-1), platelet-derived growth factor-BB (PDGF-BB), Bax, Bcl-2, cytochrome c (Cyt c), caspase-9, and caspase-3 in PASMCs. RESULTS: We found that hypoxia significantly stimulated proliferation and rendered resistance to apoptosis in PASMCs. Ipt suppressed proliferation and induced cell cycle arrest in hypoxia PASMCs. Ipt decreased the expression of cyclin D, CDK4, HIF-1, ET-1, and PDGF-BB in hypoxia PASMCs. It reversed the depolarization of Deltapsim in hypoxia PASMCs too. Ipt significantly upregulated Bax expression and downregulated Bcl-2 expression, and promoted the release of Cyt c from mitochondria to cytoplasm in hypoxia PASMCs. Furthermore, Ipt significantly activated the caspase cascades evidenced by increased expression of caspase-9 and caspase-3 in hypoxia PASMCs. CONCLUSIONS: Ipt could inhibit cell proliferation and induce apoptosis associated with cell cycle arrest, decreased ET-1, HIF-1, cyclin D, CDK4, PDGF-BB and Deltapsim, increased Bax/Bcl-2 ratio, enhanced Cyt c release, and activation of caspases in PASMCs under hypoxia status. Our data indicated that Ipt could be a therapeutic candidate for treatment of HPH. PMID- 27718462 TI - Towards patient-specific modeling of mitral valve repair: 3D transesophageal echocardiography-derived parameter estimation. AB - Transesophageal echocardiography (TEE) is routinely used to provide important qualitative and quantitative information regarding mitral regurgitation. Contemporary planning of surgical mitral valve repair, however, still relies heavily upon subjective predictions based on experience and intuition. While patient-specific mitral valve modeling holds promise, its effectiveness is limited by assumptions that must be made about constitutive material properties. In this paper, we propose and develop a semi-automated framework that combines machine learning image analysis with geometrical and biomechanical models to build a patient-specific mitral valve representation that incorporates image derived material properties. We use our computational framework, along with 3D TEE images of the open and closed mitral valve, to estimate values for chordae rest lengths and leaflet material properties. These parameters are initialized using generic values and optimized to match the visualized deformation of mitral valve geometry between the open and closed states. Optimization is achieved by minimizing the summed Euclidean distances between the estimated and image-derived closed mitral valve geometry. The spatially varying material parameters of the mitral leaflets are estimated using an extended Kalman filter to take advantage of the temporal information available from TEE. This semi-automated and patient specific modeling framework was tested on 15 TEE image acquisitions from 14 patients. Simulated mitral valve closures yielded average errors (measured by point-to-point Euclidean distances) of 1.86 +/- 1.24 mm. The estimated material parameters suggest that the anterior leaflet is stiffer than the posterior leaflet and that these properties vary between individuals, consistent with experimental observations described in the literature. PMID- 27718463 TI - Simultaneous quantification of soman and VX adducts to butyrylcholinesterase, their aged methylphosphonic acid adduct and butyrylcholinesterase in plasma using an off-column procainamide-gel separation method combined with UHPLC-MS/MS. AB - This work describes a novel and sensitive non-isotope dilution method for simultaneous quantification of organophosphorus nerve agents (OPNAs) soman (GD) and VX adducts to butyrylcholinesterase (BChE), their aged methylphosphonic acid (MeP) adduct and unadducted BChE in plasma exposed to OPNA. OPNA-BChE adducts were isolated with an off-column procainamide-gel separation (PGS) from plasma, and then digested with pepsin into specific adducted FGES*AGAAS nonapeptide (NP) biomarkers. The resulting NPs were detected by UHPLC-MS/MS MRM. The off-column PGS method can capture over 90% of BChE, MeP-BChE, VX-BChE and GD-BChE from their respective plasma materials. One newly designed and easily synthesized phosphorylated BChE nonapeptide with one Gly-to-Ala mutation was successfully reported to serve as internal standard instead of traditional isotopically labeled BChE nonapeptide. The linear range of calibration curves were from 1.00 200ngmL-1 for VX-NP, 2.00-200ngmL-1 for GD-NP and MeP-NP (R2>=0.995), and 3.00 200ngmL-1 for BChE NP (R2>=0.990). The inter-day precision had relative standard deviation (%RSD) of <8.89%, and the accuracy ranged between 88.9-120%. The limit of detection was calculated to be 0.411, 0.750, 0.800 and 1.43ngmL-1 for VX-NP, GD-NP, MeP-NP and BChE NP, respectively. OPNA-exposed quality control plasma samples were characterized as part of method validation. Investigation of plasma samples unexposed to OPNA revealed no baseline values or interferences. Using the off-column PGS method combined with UHPLC-MS/MS, VX-NP and GD-NP adducts can be unambiguously detected with high confidence in 0.10ngmL-1 and 0.50ngmL-1 of exposed human plasma respectively, only requiring 0.1mL of plasma sample and taking about four hours without special sample preparation equipment. These improvements make it a simple, sensitive and robust PGS-UHPLC-MS/MS method, and this method will become an attractive alternative to immunomagnetic separation (IMS) method and a useful diagnostic tool for retrospective detection of OPNA exposure with high confidence. Furthermore, using the developed method, the adducted BChE levels from VX and GD-exposed (0.10-100ngmL-1) plasma samples were completely characterized, and the fact that VX being more active and specific to BChE than GD was re-confirmed. PMID- 27718464 TI - Validation of a novel and rapid method for the simultaneous determination of some phenolic organohalogens in human serum by GC-MS. AB - Over the last decades, more and more studies focused on the impact of endocrine disruptors on the environment and human health. Among them, phenolic organohalogens (POHs) are a particular concern because of their structural resemblance with natural hormones. There are different methods that are known to quantify these compounds in human serum, however, the current extraction techniques are long, fastidious and using harmfull chemicals such as diazomethane and sulfuric acid. Consequently, we developed an alternative, sensitive and faster method to simultaneously quantify pentachlorophenol (PCP), tetrabromobisphenol A (TBBPA), 4 bromophenols, 7 hydroxypolychlorinated biphenyls (OH-PCBs) and 3 hydroxy-polybrominated diphenyl ether (OH-PBDEs) in human serum sample. The clean-up and the enrichment of the sample were performed in a single extraction step using strong anion-exchange solid phase cartridge. After a rapid liquid-liquid extraction step to remove acidic traces, the extract was derivatized using trimethylsilyldiazomethane (TMSD) and finally analyzed by a gas chromatograph coupled with an electron negative capture chemical ionization source combined with a triple quadrupole mass spectrometer (GC-ENCI-MS) operating in single ion monitoring. The whole procedure was validated according to the total error approach. The inter and intra assay precision were demonstrated to be lower than 20% and the relative bias to be lower than 15% in the dosing range of concentrations. The limit of quantification (LOQ) ranged from 2pgmL-1 and 5pgmL 1, except for the PCP (44.6pgmL-1) and for the 2,4,6-tribromophenol (49.6pgmL-1). Finally, the method was successfully applied to measure the POH background contamination in serum samples collected from 20 Belgian blood donors recruited in CHU Mont-Godinne (Namur, Belgium) aged between 21 and 69 years old. PMID- 27718466 TI - Mental disorders in HIV/HCV coinfected patients under antiviral treatment for hepatitis C. AB - This paper aims to review the epidemiology and management of mental disorders in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfected patients, the need for antiviral therapy in this specific population, and current treatment strategies for HIV/HCV patients with psychiatric and/or substance use disorders. This is a narrative review. Data was sourced from electronic databases and was not limited by language or date of publication. HIV infection has become a survivable chronic illness. Prevalence of HCV infection among HIV-infected patients is high ranging from 50% to 90%. Patients with psychiatric diseases have also an increased risk for HIV/HCV coinfection. The most effective strategy to decrease HCV-related morbidity and mortality in coinfection is to achieve viral eradication. Although psychiatric symptoms often appear during antiviral treatment and may be associated with the use of interferon-alpha (IFN-alpha), recent evidence suggests that many patients with comorbid mental and substance use disorders can be treated safely. Recent data indicate that IFNalpha-induced psychiatric side effects have a similar prevalence in HIV/HCV coinfected patients than in monoinfected patients and they can be managed and even prevented successfully with psychopharmacological strategies in the frame of a multidisciplinary team. New antivirals offer INF-free therapies for this specific population. PMID- 27718465 TI - Analysis of beta-agonist residues in bovine hair: Development of a UPLC-MS/MS method and stability study. AB - Beta-sympathomimetic compounds are widely used in therapy because of the bronchodilator, smooth muscle-relaxant and tocolytic properties. However, their growth promoting and performance enhancing effects are often subject to illegal use. The present work describes the development of a fast and reliable analytical multiresidue method for the confirmation 20 beta-agonist compounds in animal hair. The procedure is based on alkaline digestion, LLE with organic solvents, SPE clean up and liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) analysis, and is suitable for the public Official control of beta-agonist residues in hair sample. Validation was performed according to Commission Decision 2002/657/EC requirements. Independent samples spiked with the investigated compounds in the range 0.2-10.0MUgkg-1 are showing intra-day and inter-day precision (RSD) lower than 17.8% and 19.7%, respectively. Linearity, measured in the range of 0.1-10.0MUgkg-1, resulted with a Pearson's r>0.996. The decision limits (CCalpha) for the all investigated beta agonists resulted in the range 0.2-1.0MUgkg-1. Furthermore, the method was tested on real hair samples obtained from cattle, known as positive to clenbuterol, in order to check its effectiveness and the beta-agonists stability. PMID- 27718467 TI - Typology of schizotypy in non-clinical young adults: Psychopathological and personality disorder traits correlates. AB - Few typological studies address schizotypy in young adults. Schizotypal traits were assessed on 466 college students using the Schizotypal Personality Questionnaire-Brief (SPQ-B). Other measures evaluated personality traits previously associated with schizotypy (borderline, obsessionnal, and autistic traits), psychopathological symptoms (suicidal ideations, depressive and obsessive-compulsive symptoms) and psychosocial functioning. A factor analysis was first performed on SPQ-B results, leading to four factors: negative schizotypy, positive schizotypy, social anxiety, and reference ideas. Based on these factors, a cluster analysis was conducted, which yielded four clearly distinct groups characterized by "Low" (non schizotypy), "High schizotypy" (mixed positive and negative), "Positive schizotypy", and "Social impairment". Regarding personality disorder traits and psychopathological symptoms, the "High schizotypy" cluster scored higher than the "Positive" and the "Social impairment" groups, which scored higher than the "Low" cluster. The "Positive" group had higher levels of interpersonal relationships than in the "High" and the "Social impairment" clusters, suggesting that positive schizotypy was associated to benefits such as perceived social relationships. Nevertheless the "Positive" cluster was also linked to high levels of personality disorder traits and psychopathological symptoms, and to low academic achievement, at levels similar those observed in the "Social impairment" cluster, confirming an unhealthy side to positive schizotypy. PMID- 27718468 TI - Neurocognition in help-seeking individuals at risk for psychosis: Prediction of outcome after 24 months. AB - An important aim in schizophrenia research is to optimize the prediction of psychosis and to improve strategies for early intervention. The objectives of this study were to explore neurocognitive performance in individuals at risk for psychosis and to optimize predictions through a combination of neurocognitive and psychopathological variables. Information on clinical outcomes after 24 months was available from 118 subjects who had completed an extensive assessment at baseline. Subjects who had converted to psychosis were compared with subjects who had not. Multivariate Cox regression analyses were used to determine which baseline measure best predicted a conversion to psychosis. The premorbid IQ and the neurocognitive domains of processing speed, learning/memory, working memory and verbal fluency significantly discriminated between converters and non converters. When entered into multivariate regression analyses, the combination of PANSS positive/negative symptom severity and IQ best predicted the clinical outcomes. Our results confirm previous evidence suggesting moderate premorbid cognitive deficits in individuals developing full-blown psychosis. Overall, clinical symptoms appeared to be a more sensitive predictor than cognitive performance. Nevertheless, the two might serve as complementary predictors when assessing the risk for psychosis. PMID- 27718469 TI - Depression and anxiety mediate the relationship between temperament and character and psychotic-like experiences in healthy subjects. AB - In this study we examined the hypothesis that depression and anxiety may mediate the relationship between personality traits and both positive and negative psychotic-like experiences (PLEs) in healthy adults. The Community Assessment of Psychic Experiences (CAPE) scale, Temperament and Character Inventory (TCI), Beck Depression Inventory (BDI) and State and Trait Anxiety Inventory (STAI) were administered to 492 healthy individuals. Multiple stepwise regression and mediation analyses were performed to examine whether depressive and anxiety symptoms influence the relationship between the TCI dimensions and positive and negative PLEs. Self-transcendence, persistence, novelty-seeking and self directedness significantly predicted positive PLEs; self-directedness and harm avoidance were predictable for negative PLEs. Self-transcendence, self directedness, persistence and harm avoidance also predicted the distress caused by positive PLEs, whereas self-directedness and harm avoidance predicted distress raised by negative PLEs. Depressive symptoms and the state of anxiety partially mediated the linkage between self-directedness and positive PLEs, and between self-directedness, harm avoidance and negative PLEs. Our findings confirm that the personality pattern influences both positive and negative PLEs as well as distress caused by experiencing positive and negative PLEs, and they indicate that certain personality traits may influence the development of PLEs via the emotional pathway of heightened depression and anxiety. PMID- 27718470 TI - Antagonizing STAT3 activation with benzo[b]thiophene 1, 1-dioxide based small molecules. AB - STAT3 is an attractive therapeutic target for cancer therapy. However, due to low potency or poor druggability, none of its inhibitors are clinically available. Herein, a series of aminobenzo[b]thiophene 1, 1-dioxides with good drug-likeness properties were designed, synthesized and evaluated as STAT3 inhibitors. Most of them exhibited higher antitumor activity than the small-molecule STAT3 inhibitor, Stattic. Compound 15 was the most potent and had an IC50 range in 0.33-0.75 MUM in various cancer cell lines. The overexpressed and IL-6 induced phosphorylation levels of STAT3 were both inhibited by 15 without influencing the phosphorylation levels of the upstream kinases Src and Jak2. 15 also suppressed the expressions of STAT3 downstream gene, Bcl-2. 15 effectively increased the ROS levels of cancer cells, induced cancer cell apoptosis and abolished the colony formation ability of cancer cells without affecting bypass kinase p-Erk. Furthermore, 15in vivo induced significant antitumor responses, and exhibited less toxicity than Doxorubicin. Together, this study described a class of new STAT3 inhibitors as antitumor agents. PMID- 27718471 TI - Pyrazole derived ultra-short antimicrobial peptidomimetics with potent anti biofilm activity. AB - In this study, we report on the first chemical synthesis of ultra-short pyrazole arginine based antimicrobial peptidomimetics derived from the newly synthesized N alkyl/aryl pyrazole amino acids. Through the systematic tuning of hydrophobicity, charge, and peptide length, we identified the shortest peptide Py11 with the most potent antimicrobial activity. Py11 displayed greater antimicrobial activity against antibiotic-resistant bacteria, including MRSA, MDRPA, and VREF, which was approximately 2-4 times higher than that of melittin. Besides its higher selectivity (therapeutic index) toward bacterial cells than LL-37, Py11 showed highly increased proteolytic stability against trypsin digestion and maintained its antimicrobial activity in the presence of physiological salts. Interestingly, Py11 exhibited higher anti-biofilm activity against MDRPA compared to LL-37. The results from fluorescence spectroscopy and transmission electron microscopy (TEM) suggested that Py11 kills bacterial cells possibly by integrity disruption damaging the cell membrane, leading to the cytosol leakage and eventual cell lysis. Furthermore, Py11 displayed significant anti-inflammatory (endotoxin neutralizing) activity by inhibiting LPS-induced production of nitric oxide (NO) and TNF-alpha. Collectively, our results suggest that Py11 may serve as a model compound for the design of antimicrobial and antisepsis agents. PMID- 27718472 TI - Discovery of nanomolar ligands with novel scaffolds for the histamine H4 receptor by virtual screening. AB - The involvement of histamine H4 receptor (H4R) in immune cells chemotaxis and mediator release makes it an attractive target for the treatment of inflammation disorders. A decade of medicinal chemistry efforts has led to several promising ligands, although the chemical structures described so far possesses a singular limited diversity. We report here the discovery of novel structures, belonging to completely different scaffolds. The virtual screening was planed as a two-steps process. First, using a "scout screening" methodology, we have experimentally probed the H4R ligand binding site using a small size chemical library with very diverse structures, and identified a hit that further assist us in refining a raw 3D homology model. Second, the refined 3D model was used to conduct a widened virtual screening. This two-steps strategy proved to be very successful, both in terms of structural diversity and hit rate (23%). Moreover, the hits have high affinity for the H4R, with most potent ligands in the nanomolar range. PMID- 27718473 TI - Synthesis and anti-mitotic activity of 6,7-dihydro-4H-isothiazolo[4,5-b]pyridin-5 ones: In vivo and cell-based studies. AB - A series of 3,7-diaryl-6,7-dihydroisothiazolo [4,5-b]pyridin-5(4H)-ones 8 and 9 was synthesized by multicomponent condensation of 3-aryl-5-isothiazolecarboxylic acid esters 4a-f with aromatic (or thienyl) aldehydes 7 and Meldrum's acid in an acidic medium. The targeted compounds were evaluated for their antimitotic microtubule destabilizing activity using in vivo phenotypic sea urchin embryo model and in vitro human cancer cell-based assays. Selected dihydroisothiazolopyridinones altered sea urchin egg cleavage in 2-10 nM concentrations together with significant cytotoxicity against cancer cells including chemoresistant cell lines (IC50 in submicromolar - low nanomolar concentration range). Both approaches confirmed antimitotic microtubule destabilizing mechanism of action of the izothiazole derivatives. Structure activity relationship study determined the importance of p-methoxybenzene A-ring for the antiproliferative effect. The most potent compound 9b containing p methoxybenzene A-ring and thiophene B-ring caused mitotic arrest and disintegration of cell microtubules. PMID- 27718474 TI - Synthesis and evaluation of N-substituted 2-amino-4,5-diarylpyrimidines as selective adenosine A1 receptor antagonists. AB - We report the synthesis and biological evaluation of new 2-amino-4,5 diarylpyrimidines as selective antagonists at the adenosine A1 receptor. The scaffold they are based upon is a deaza variation of a previously reported collection of 3-amino-5,6-diaryl-1,2,4-triazines, members of which had a subnanomolar affinity but limited selectivity over the A2A subtype. Initially, similar structure-affinity relationships at the 5-aryl ring were established, and then emphasis was put on increasing selectivity at the hA1AR by introducing substituents on the N2-position, all the while maintaining a nanomolar affinity. Compound 3z, bearing a trans 4-hydroxycyclohexyl substituent, was identified as a potent (Ki(hA1AR) = 7.7 nM) and selective (Ki(hA2AAR) = 1389 nM) antagonist at the human adenosine A1 receptor. Computational docking was effected at the A1 and A2A subtypes, rationalizing the effect of the 4-hydroxycyclohexyl substituent on selectivity, in relation with the nature of the substituent on the 5-position of the pyrimidine. PMID- 27718475 TI - Influence of the dominance of must fermentation by Torulaspora delbrueckii on the malolactic fermentation and organoleptic quality of red table wine. AB - Torulaspora delbrueckii can improve wine aroma complexity, but its impact on wine quality is still far from being satisfactory at the winery level, mainly because it is easily replaced by S. cerevisiae yeasts during must fermentation. New T. delbrueckii killer strains were selected to overcome this problem. These strains killed S. cerevisiae yeasts and dominated fermentation better than T. delbrueckii non-killer strains when they were single-inoculated into crushed red grape must. All the T. delbrueckii wines, but none of the S. cerevisiae wines, underwent malolactic fermentation. Putative lactic acid bacteria were always found in the T. delbrueckii wines, but none or very few in the S. cerevisiae wines. Malic acid degradation was the greatest in the wines inoculated with the killer strains, and these strains reached the greatest dominance ratios and had the slowest fermentation kinetics. The T. delbrueckii wines had dried-fruit/pastry aromas, but low intensities of fresh-fruit aromas. The aroma differences between the T. delbrueckii and the S. cerevisiae wines can be explained by the differences that were found in the amounts of some fruity aroma compounds such as isoamyl acetate, ethyl hexanoate, ethyl octanoate, and some lactones. This T. delbrueckii effect significantly raised the organoleptic quality scores of full-bodied Cabernet Sauvignon red wines inoculated with the killer strains. In particular, these wines were judged as having excellent aroma complexity, mouth-feel, and sweetness. PMID- 27718476 TI - Development of visual peak selection system based on multi-ISs normalization algorithm to apply to methamphetamine impurity profiling. AB - The aim of this study is to improve resolution of impurity peaks using a newly devised normalization algorithm for multi-internal standards (ISs) and to describe a visual peak selection system (VPSS) for efficient support of impurity profiling. Drug trafficking routes, location of manufacture, or synthetic route can be identified from impurities in seized drugs. In the analysis of impurities, different chromatogram profiles are obtained from gas chromatography and used to examine similarities between drug samples. The data processing method using relative retention time (RRT) calculated by a single internal standard is not preferred when many internal standards are used and many chromatographic peaks present because of the risk of overlapping between peaks and difficulty in classifying impurities. In this study, impurities in methamphetamine (MA) were extracted by liquid-liquid extraction (LLE) method using ethylacetate containing 4 internal standards and analyzed by gas chromatography-flame ionization detection (GC-FID). The newly developed VPSS consists of an input module, a conversion module, and a detection module. The input module imports chromatograms collected from GC and performs preprocessing, which is converted with a normalization algorithm in the conversion module, and finally the detection module detects the impurities in MA samples using a visualized zoning user interface. The normalization algorithm in the conversion module was used to convert the raw data from GC-FID. The VPSS with the built-in normalization algorithm can effectively detect different impurities in samples even in complex matrices and has high resolution keeping the time sequence of chromatographic peaks the same as that of the RRT method. The system can widen a full range of chromatograms so that the peaks of impurities were better aligned for easy separation and classification. The resolution, accuracy, and speed of impurity profiling showed remarkable improvement.

AB - We determined the extent to which DNA methylation mediates the effects of maternal cognitive appraisal of a natural disaster during pregnancy on offspring growth at age 13. Negative maternal cognitive appraisal predicted both lower BMI and central adiposity via DNA methylation of diabetes-related genes, suggesting a protective role of epigenetics. PMID- 27718478 TI - An experimental study of shear-dependent human platelet adhesion and underlying protein-binding mechanisms in a cylindrical Couette system. AB - Undesirable thrombotic reactions count among the most frequent and serious complications for patients who rely on the use of medical devices. To improve the design of medical devices, it is essential to develop a more precise understanding of platelet reactions. Clinical studies and experiments have shown a strong dependence of platelet deposition behavior on the flow. However, today the influence of hemodynamic parameters such as the shear rate on thrombotic reactions is not well understood. For the study of the shear-dependent mechanisms leading to the activation, adhesion and aggregation of platelets, a Couette flow system was used to investigate thrombocyte behavior with regard to well-defined flow conditions at shear-rate values between gamma=400 $?dot ?gamma = {?rm{400}}$ and 1400 1/s. Results were calculated for physiological temperature. It could be shown that the platelet adhesion density increased with increasing shear rates up to gamma=800 1/s $?dot ?gamma = {?rm{800 1/s}}$ and the adhesion pattern was homogeneous. At gamma=800 1/s, $?dot ?gamma = {?rm{800 1/s}},$ a sudden drop in platelet adhesion density occurred and platelets adhered in filaments. Fluorescence microscopy results of von Willebrand factor (vWF) confirm that a shear rate of gamma=800 1/s $?dot ?gamma = {?rm{800 1/s}}$ represents the threshold where a switch of the platelet-binding mechanism from fibrinogen mediated to vWF-mediated platelet adhesion takes place. PMID- 27718479 TI - Fabrication of multifunctional CaP-TC composite coatings and the corrosion protection they provide for magnesium alloys. AB - Two major problems with magnesium (Mg) alloy biomaterials are the poor corrosion resistance and infection associated with implantation. In this study, a novel calcium phosphate (CaP)/tetracycline (TC) composite coating for Mg implants that can both improve the corrosion resistance of Mg and release a drug in a durable way is reported. Scanning electron microscope (SEM) images showed that TC additives make the CaP coating more compact and uniform. Electrochemical tests indicated CaP/TC coatings can provide excellent corrosion protection for Mg alloy substrates. Besides, TC additives can also provide effective prevention of bone infection and inflammation due to its broad-spectrum antibacterial properties. The one-step hydrothermal process reported here greatly simplified the multi-step fabrication of smart coatings reported previously. PMID- 27718480 TI - Can non-cholesterol sterols and lipoprotein subclasses distribution predict different patterns of cholesterol metabolism and statin therapy response? AB - BACKGROUND: Cholesterol homeostasis disorders may cause dyslipidemia, atherosclerosis progression and coronary artery disease (CAD) development. Evaluation of non-cholesterol sterols (NCSs) as synthesis and absorption markers, and lipoprotein particles quality may indicate the dyslipidemia early development. This study investigates associations of different cholesterol homeostasis patterns with low-density (LDL) and high-density lipoproteins (HDL) subclasses distribution in statin-treated and statin-untreated CAD patients, and potential use of aforementioned markers for CAD treatment optimization. METHODS: The study included 78 CAD patients (47 statin-untreated and 31 statin-treated) and 31 controls (CG). NCSs concentrations were quantified using gas chromatography- flame ionization detection (GC-FID). Lipoprotein subclasses were separated by gradient gel electrophoresis. RESULTS: In patients, cholesterol synthesis markers were significantly higher comparing to CG. Cholesterol synthesis markers were inversely associated with LDL size in all groups. For cholesterol homeostasis estimation, each group was divided to good and/or poor synthetizers and/or absorbers according to desmosterol and beta-sitosterol median values. In CG, participants with reduced cholesterol absorption, the relative proportion of small, dense LDL was higher in those with increased cholesterol synthesis compared to those with reduced synthesis (p<0.01). LDL I fraction was significantly higher in poor synthetizers/poor absorbers subgroup compared to poor synthetizers/good absorbers (p<0.01), and good synthetizers/poor absorbers (p<0.01). Statin-treated patients with increased cholesterol absorption had increased proportion of LDL IVB (p<0.05). CONCLUSIONS: The results suggest the existence of different lipoprotein abnormalities according to various patterns of cholesterol homeostasis. Desmosterol/beta-sitosterol ratio could be used for estimating individual propensity toward dyslipidemia development and direct the future treatment.

PMID- 27718483 TI - Lyophilized hemoglobin E control material for the dichlorophenol-indophenol (DCIP) test. PMID- 27718484 TI - Progress and impact of enzyme measurement standardization. AB - International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) has established reference measurement procedures (RMPs) for the most popular enzymes. Manufacturers should assign values to commercial calibrators traceable to these RMPs to achieve equivalent results in clinical samples, independent of reagent kits, instruments, and laboratory where the measurement is carried out. The situation is, however, far from acceptable. Some manufacturers continue to market assays giving results that are not traceable to internationally accepted RMPs. Meanwhile, end-users often do not abandon assays with demonstrated insufficient quality. Of the enzyme measurements, creatine kinase (CK) is satisfactorily standardized and a substantial improvement in performance of marketed gamma glutamyltranspeptidase (GGT) assays has been demonstrated. Conversely, aminotransferase measurements often exceed the desirable analytical performance because of the lack of pyridoxal-5-phosphate addition in the commercial reagents. Measurements of lactate dehydrogenase (LDH), alkaline phosphatase (ALP), and alpha-amylase (AMY) still show major disagreement, suggesting the need for improvement in implementing traceability to higher-order references. This is mainly the result of using assays with different analytical selectivities for these enzymes. The definition by laboratory professionals of the clinically acceptable measurement uncertainty for each enzyme together with the adoption by EQAS of commutable materials and use of an evaluation approach based on trueness represent the way forward for reaching standardization in clinical enzymology.

AB - BACKGROUND: The fraction of an absorbed drug metabolized by the different hepatic cytochrome P450 (CYP) enzymes, relative to total hepatic CYP metabolism (fmCYP), can be estimated by measuring the inhibitory effects of presumably selective CYP inhibitors on the intrinsic metabolic clearance of a drug using human liver microsomes. However, the chemical inhibition data are often affected by cross reactivities of the chemical inhibitors used in this assay. METHODS: To overcome this drawback, the cross-reactivities exhibited by six chemical inhibitors (furafylline, montelukast, sulfaphenazole, ticlopidine, quinidine and ketoconazole) were quantified using specific CYP enzyme marker reactions. The determined cross-reactivities were used to correct the in vitro fmCYPs of nine marketed drugs. The corrected values were compared with reference data obtained by physiologically based pharmacokinetics simulation using the software SimCYP. RESULTS: Uncorrected in vitro fmCYPs of the nine drugs showed poor linear correlation with their reference data (R2=0.443). Correction by factoring in inhibitor cross-reactivities significantly improved the correlation (R2=0.736). CONCLUSIONS: Correcting in vitro chemical inhibition results for cross reactivities appear to offer a straightforward and easily adoptable approach to provide improved fmCYP data for a drug. PMID- 27718492 TI - Efficacy of growth hormone therapy in Kearns-Sayre syndrome: the KIGS experience. AB - Kearns-Sayre syndrome (KSS) is characterized by external ophthalmoplegia, retinal pigmentation and cardiac conduction defects due to mitochondrial DNA (mtDNA) deletions. Short stature and growth hormone (GH) deficiency have been reported in KSS, but data on GH treatment is limited. We describe the clinical presentation, phenotype evolution, and response to GH in a patient with KSS and report data on eight additional KSS patients from the KIGS database. Our patient with KSS and GH deficiency achieved a final adult height at -0.8 SDS. In the KIGS database GH treatment resulted in mean improvement in height from -3.9 to -2.9 SDS in patients with KSS. Two patients did not show growth improvement. Our data shows improvement in height SDS in our patient and mixed results in eight additional patients from the KIGS database after treatment with GH. Heterogeneity in responsiveness may relate to presence of GH deficiency or severity of underlying mitochondrial dysfunction. PMID- 27718491 TI - A 10-year experience using combined lipid-lowering pharmacotherapy in children and adolescents. AB - BACKGROUND: Current pediatric guidelines for heterozygous familial hypercholesterolemia (HeFH) propose pharmacotherapy (PT) with statins from age 8 to 10 years; however, schemes with absorption inhibitors combined with statins, could be started earlier. The aim of the study was to show the 10-year results of a combined treatment protocol. METHODS: Prospective, descriptive and analytical study. Pediatric patients (n=70; mean age at PT initiation 9.3 years [range, 2 17.5]) with HeFH who required PT between 2005 and 2015 were included. All patients >=10 years, with LDL >190 mg/dL or >160 mg/dL with one cardiovascular risk factor (CVRF) or >130 mg/dL with two or more CVRF; and those patients 5-10 years and with LDL-C >240 mg/dL or a family history of a cardiovascular event before 40 years, were medicated. After a period on a lipid-lowering diet (LLD), all patients were started on ezetimibe. Patients who did not achieve the treatment goal were given statins. The variables were: age, age at PT initiation, duration of PT, initial LDL-C, mean LDL-C during ezetimibe monodrug therapy, mean LDL-C during combined PT, and percentage of LDL decrease. RESULTS: LDL-C levels were: Baseline: 235 mg/dL+/-55; after 3 months on ezetimibe: 167 mg/dL+/-47 (decrease: -27.62%). In 18 patients who did not reach the treatment goal atorvastatin was added and their LDL-C decreased -41.5% (p: 0.02). Overall, mean final LDL-C was 155 mg/dL+/-30.4 (range, 98-257) and treatment goals were reached in 74% of the patients. No severe side effects were reported. CONCLUSIONS: Combined and sequential treatment starting at early ages was shown to be safe and effective over this follow-up period. PMID- 27718493 TI - Diagnostic accuracy of fetal scalp lactate for intrapartum acidosis compared with scalp pH. AB - OBJECTIVE: To determine the diagnostic accuracy of fetal scalp lactate sampling (FSLS) and to establish an optimal cut-off value for intrapartum acidosis compared with fetal scalp pH. METHODS: A 20-month retrospective cohort study was conducted of all neonates delivered in our institution for whom fetal scalp blood sampling (FSBS) was performed, matching their intrapartum gasometry to their cord gasometry at delivery (n=243). The time taken from the performance of scalp blood sampling to arterial umbilical cord gas acquisition was 45 min at most. Five arterial cord gasometry patterns were set for assessing the predictive ability of both techniques. Subsequent obstetric management for a pathological value was analysed considering the use of both techniques. RESULTS: The optimal cut-off value for FSLS was 4.8 mmol/L: this value has 100% sensitivity and 63% specificity for umbilical arterial cord gas pH<=7.0 and base deficit (BD)>=12 detection, and 100% sensitivity and 64% specificity for umbilical arterial cord gas pH<=7.10 and BD>=12 detection, with a false negative rate of <1.3%, improving fetal scalp pH performance. FSLS showed the best area under the curve (AUC) of 0.86 and 0.84 for both arterial cord gasometry patterns, respectively. Expedite birth following lactate criteria would have been the same as following pH criteria (92 obstetric interventions) with no cases of missed metabolic acidosis. In the cohort, 19.8% of cases were discordant, but no cases of metabolic acidosis were in this group. CONCLUSIONS: FSLS improves the detection of metabolic acidosis via fetal scalp pH with an optimal cut-off value of 4.8 mmol/L. FSLS can be used without increasing obstetrical interventions or missing metabolic acidosis. PMID- 27718494 TI - The value of ultrasound measurement of cervical length and parity in prediction of cesarean section risk in term premature rupture of membranes and unfavorable cervix. AB - AIM: To evaluate the influence of cervical length (CL) and parity as prediction factors for assessment of cesarean section (CS) risk in women with premature rupture of membranes (PROM) at term and unfavorable cervix, undergoing induction of labor (IOL) with dinoprostone intracervical gel. METHODS: A prospective study involved 50 nulliparous and 51 multiparous women admitted for IOL. Pre-induction CL was measured and delivery outcomes were recorded. RESULTS: Nulliparous women were younger than the multiparous (26.6+/-5.2 vs. 30.5+/-4.9; P<0.001) and had longer pre-induction CL (35.6+/-5.5 vs. 31.5+/-4.8; P<0.001) and induction delivery interval (582 vs. 420 min; P<0.001). There was no difference in the mode of delivery, CS indications, Apgar score, neonatal weight, the rate of neonatal intensive care unit admission and perinatal death in respect of parity. CL was significantly shorter in vaginal vs. cesarean deliveries regardless of parity (31.4 vs. 38.8 mm, P<0.001, respectively). Cut-off values of CL for predicting CS were 37.5 mm in nulliparae and 34.5 mm in multiparae. CONCLUSIONS: CLs of 37.5 mm in nulliparae and 34.5 mm in multiparae were determined as the cut-off values in predicting CS risk in women with PROM at term and unfavorable cervix. PMID- 27718495 TI - Risk of recurrent preterm birth among women according to change in partner. AB - There is well-established literature indicating change in partner as a risk for preeclampsia, yet the research on the risk of preterm birth after a change in partners has been sparse and inconsistent. Using a population of California live born singletons, we aimed to determine the risk of preterm birth after a change in partner between the first and second pregnancies. The risk of preterm and early term delivery in the second pregnancy was calculated for mothers who did or did not change partners between births with the referent group as women who delivered both pregnancies at term and did not change partners. Adjusted odds ratios (ORs) and their 95% confidence intervals (CIs) were calculated. Relative to women who delivered at 39 weeks or later in the second pregnancy and did not change partners, preterm birth risks were somewhat lower for women who changed partners between the first and second pregnancies compared to those women who did not change partners. For example, 10.6% of women who did not change partners and delivered their second pregnancy before 34 weeks also delivered their first pregnancy before 34 weeks, while 8.5% of women who changed partners delivered before 34 weeks. Findings suggest partner change may alter the risk of preterm birth. PMID- 27718496 TI - Effect of acute stress on auditory processing: a systematic review of human studies. AB - Stress is an integral part of modern life. Although there is a large body of literature regarding the harmful effects of chronic stress on different aspects of human life, acute stress is the most common form of stress, resulting from the demands and pressures of the recent past and the anticipated demands and pressures of the near future. In spite of its pervasive nature, less attention has been paid to the impact of acute stress on sensory processing than to the consequences of chronic stress, particularly concerning auditory processing. In this systematic review, the impact of experimental acute stress on the auditory processing of healthy adults was investigated. The results revealed the adverse effects of acute physical and psychological stresses on auditory processing. According to the open field of research on stress and the auditory system and the high possibility of experiencing different types of acute stresses in various life environments, including testing places, it seems that more investigations are needed to identify and manage different types of acute stresses in both clinical and research situations. PMID- 27718497 TI - The relationship between study strategies and academic performance. AB - Objectives: To investigate if and to what extent the Learning and Study Strategy Inventory (LASSI) and the Self-Directed Learning Readiness Scale (SDLRS) yield academic performance predictors; To examine if LASSI findings are consistent with previous research. Methods: Medical school students completed the LASSI and SDLRS before their first and second years (n = 168). Correlational and regression analyses were used to determine the predictive value of the LASSI and the SDLRS. Paired t-tests were used to test if the two measurement points differed. Bivariate correlations and R2s were compared with five other relevant studies. Results: The SDLRS was moderately correlated with all LASSI subscales in both measures (r(152) =.255, p=.001) to (r(152) =.592, p =.000). The first SDLRS, nor the first LASSI, were predictive of academic performance. The second LASSI measure was a significant predictor of academic performance (R2(138) = 0.188, p = .003). Six prior LASSI studies yielded a range of R2s from 10-49%. Conclusions: The SDLRS is moderately correlated with all LASSI subscales. However, the predictive value of the SDLRS and LASSI differ. The SDLRS does not appear to be directly related to academic performance, but LASSI subscales: Concentration, Motivation, Time Management, and Test Strategies tend to be correlated. The explained LASSI variance ranges from 10% to 49%, indicating a small to substantial effect. Utilizing the LASSI to provide medical school students with information about their strengths and weaknesses and implementing targeted support in specific study strategies may yield positive academic performance outcomes. PMID- 27718498 TI - The activity of class I, II, III and IV alcohol dehydrogenase isoenzymes and aldehyde dehydrogenase in the sera of bladder cancer patients. AB - OBJECTIVES: Studies on alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activity in the sera of patients with malignant neoplasms show that cancer cells in many organs may release ADH isoenzymes into the blood. The aim of this study was to investigate the differences in the activity of ADH isoenzymes and ALDH in the sera of patients with bladder cancer (BCa), and with different grades of the disease. MATERIAL AND METHODS: Blood samples were taken from 39 patients with BCa (15 patients with low-grade and 24 with high-grade BCa) and from 60 healthy subjects. Class III and IV of ADH and total ADH activity were measured using the photometric method, while class I and II ADH and ALDH activity using the fluorometric method with class-specific fluorogenic substrates. RESULTS: The activity of the class I ADH isoenzyme and total ADH was significantly higher in the sera of BCa patients as compared to control group. Analysis of ALDH activity did not show statistically significant differences between the tested groups. Significantly higher total activity of ADH in comparison to control was found in both, low-grade and high-grade BCa group. The activity of ADH class I was also significantly higher in high-grade BCa group when compared to low-grade patients and controls. CONCLUSION: The increase of total ADH activity in the sera of BCa patients seems to be caused by isoenzymes released from cancerous cells. The higher activity of ADH I probably resulted from metastatic tumors as significant increase was detected only in the sera of high-grade bladder cancer patients. PMID- 27718499 TI - Amentoflavone prevents sepsis-associated acute lung injury through Nrf2-GCLc mediated upregulation of glutathione. AB - Sepsis is a serious medical problem and is one of the main causes of high mortality in intensive care units. Fifty percent of patients with severe sepsis will develop acute lung injury (ALI). Amentoflavone (AMF) is a polyphenolic compound possessing potent anti-inflammatory activities. The study aimed to explore the protective effects of AMF against ALI in cecal ligation and puncture (CLP)-induced septic rats. The results showed that AMF administration protected against septic ALI, as reflected by marked amelioration of histological injury of lung tissues and decrease of pulmonary edema in CLP-treated rats. AMF ameliorated CLP-induced increase of systemic and lung TNFalpha and IL-1beta and binding activity of p65 NF-kappaB, indicating the inhibition of inflammation. Moreover, AMF prevented CLP-induced oxidative stress, as evidenced by increase of oxygen consumption rate, decrease of TBARS content, increase of SOD activity and GSH level in lung tissue of CLP-treated rats. CLP resulted in significant decrease of mRNA expression of Nrf2 and GCLc, which was inhibited by AMF. AMF-induced protective effects on ALI, inflammation, and oxidative stress were inhibited by lentivirus shRNA-mediated silence of Nrf2 and buthionine sulphoximine (BSO), an inhibitor of GSH synthesis. AMF increased Nrf2-binding activity in GCLc promoters in lung tissue of CLP-treated rats. The results suggested that AMF protected against ALI in septic rats through upregulation of Nrf2-GCLc signaling, enhancement of GSH antioxidant defense, reduction of oxidative stress and final amelioration of inflammation and histological injury of lung. The data provide new therapeutic options for the treatment of sepsis-associated ALI. PMID- 27718500 TI - Patients with lichen sclerosus experience moderate satisfaction with treatment and impairment of quality of life: results of a cross-sectional study. AB - BACKGROUND: Although they are considered relevant, little is known about satisfaction with treatment and health-related quality of life (HRQoL) among patients with lichen sclerosus (LS). OBJECTIVES: In a cross-sectional study, we aimed to examine (i) satisfaction with treatment, (ii) patient characteristics associated with satisfaction and (iii) HRQoL in Dutch patients with LS. METHODS: Members of the Dutch LS Patient Association (n = 750) were invited to complete a web-based survey. We measured satisfaction with treatment with a study-specific questionnaire, and HRQoL with the Skindex-29. We calculated domain scores for symptoms, emotions and functioning, and categorized scores into little, mildly, moderately or severely impaired HRQoL. We used a multiple linear regression analysis to examine whether patient characteristics were associated with treatment satisfaction. RESULTS: In total 303 patients (40.4%) were included. Patients under current treatment (n = 265, 87.5%) were moderately satisfied with their treatment. Patients rated 'treatment effectiveness' as most important, although 58 (22%) were dissatisfied with the effectiveness of their current treatment. More impairment on the HRQoL emotions domain and a higher degree of disease severity were both associated with lower satisfaction with treatment and explained in total 13.5% of the variance in treatment satisfaction. On all HRQoL domains, one-third of the patients (range 34.7-38.9%) reported severe impairment. CONCLUSIONS: Patients with LS are moderately satisfied with their treatment, and one-third of patients experience severe impairment of HRQoL. To improve dermatological care, we recommend enhancement of doctor-patient communication, information provision and organization, which may be more amenable to change than treatment effectiveness or safety. PMID- 27718501 TI - Progress toward reaction monitoring at variable temperatures: a new stopped-flow NMR probe design. AB - A stopped-flow NMR probe is described that enables fast flow rates, short transfer times, and equilibration of the reactant magnetization and temperature prior to reaction. The capabilities of the probe are demonstrated by monitoring the polymerization of lactide as catalyzed by the air-sensitive catalyst 1,3 dimesitylimidazol-2-ylidene (IMes) over the temperature range of -30 to 40 degrees C. The incorporation of stopped-flow capabilities into an NMR probe permits the rich information content of NMR to be accessed during the first few seconds of a fast reaction.

AB - OBJECTIVE: Pelvic floor muscle (PFM) dysfunction seems to play an important role in the pathophysiology of pelvic pain, including that associated with deep infiltrating endometriosis (DIE). The aim of this study was to evaluate the static and dynamic morphometry of the PFM using three-dimensional (3D) and four dimensional (4D) transperineal ultrasound in women with DIE compared with asymptomatic healthy women. METHODS: This was a pilot, prospective study conducted at our tertiary center between March and November 2015. Fifty nulliparous women with DIE (study group) and 35 nulliparous asymptomatic healthy women (control group) were included. 3D/4D transperineal ultrasound examination of the PFM was performed in both groups. Levator hiatal area (LHA) and anteroposterior and left-right transverse diameters were evaluated at rest, on maximum PFM contraction and on maximum Valsalva maneuver. Persistent levator ani muscle (LAM) coactivation during Valsalva maneuver was investigated. RESULTS: Compared with the control group, women with DIE had a smaller LHA at rest (P = 0.03) and during Valsalva maneuver (P < 0.01). Furthermore, reduction in LHA during PFM contraction (P < 0.001) and enlargement in LHA during Valsalva maneuver (P = 0.01) were significantly less marked. In comparison with controls, women with DIE presented a higher frequency of LAM coactivation during Valsalva maneuver, although this difference did not reach statistical significance (P = 0.05). CONCLUSIONS: 3D and 4D transperineal ultrasound is an objective and non invasive method for PFM morphometry and may have a role in detecting PFM dysfunction in women with DIE.

AB - BACKGROUND: Cutaneous malignant melanoma arises from transformed melanocytes de novo or from congenital or acquired melanocytic naevi. We have recently reported that T-type Ca2+ channels (TT-Cs) are upregulated in human melanoma and play an important role in cell proliferation. OBJECTIVES: To describe for the first time in formalin-fixed paraffin-embedded tissue the immunoexpression of TT-Cs in biopsies of normal skin, acquired melanocytic naevi and melanoma, in order to evaluate their role in melanomagenesis and/or tumour progression, their utility as prognostic markers and their possible use in targeted therapies. METHODS: Tissue samples from normal skin, melanocytic naevi and melanoma were subjected to immunohistochemistry for two TT-Cs (Cav3.1, Cav3.2); markers of proliferation (Ki67), the cell cycle (cyclin D1), hypoxia (Glut1), vascularization (CD31) and autophagy (LC3); BRAF V600E mutation (VE1) and phosphatase and tensin homologue (PTEN). Immunostaining was evaluated by histoscore. In silico analysis was used to assess the prognostic value of TT-C overexpression. RESULTS: TT-C immunoexpression increased gradually from normal skin to common naevi, dysplastic naevi and melanoma samples, but with differences in the distribution of both isoforms. Particularly, Cav3.2 expression was significantly higher in metastatic melanoma than in primary melanoma. Statistical correlation showed a linear interaction between PTEN loss/BRAF V600E/Cav3.1/LC3/ Ki67/cyclin D1/Cav3.2/Glut1. Disease-free survival (DFS) and overall survival correlated inversely with overexpression of Cav3.2. DFS also correlated inversely with overexpression of Cav3.1. CONCLUSIONS: TT-C immunoexpression on melanocytic neoplasms is consistent with our previous in vitro studies and appears to be related to tumour progression. TT-C upregulation can be considered as a prognostic marker using The Cancer Genome Atlas database. The high expression of Cav3.2 in metastatic melanoma encourages the investigation of the use of TT-C blockers in targeted therapies. PMID- 27718504 TI - Cancer-and-treatment-specific distress and its impact on posttraumatic stress in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). AB - BACKGROUND: In this prospective multicenter study, we investigated cancer-and treatment-specific distress (CTXD) and its impact on symptoms of posttraumatic stress disorder (PTSD) in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). METHODS: Patients were consulted before (T0, N = 239), 3 (T1, N = 150), and 12 months (T2, N = 102) after HSCT. Medical (eg, diagnosis and pretreatment) and demographic information, CTXD and PTSD (PCL-C) were assessed. RESULTS: Random intercept models revealed that the sum score of CTXD was highest pre-HSCT (T0), decreased by T1 (gamma = -.18, 95% CI [-.26/-.09]), and by T2 (gamma = -.10, 95% CI [-.20/-.00]). Uncertainty, family strain, and health burden were rated most distressing during HSCT. Uncertainty and family strain decreased from T0 to T1 (gamma = -.30, 95% CI [-.42/-.17]; gamma = -.10, 95% CI [-.20/ .00]) and health burden from T1 to T2 (gamma = -.21, 95% CI [-.36/.05]). Women were more likely to report uncertainty (gamma = .38, 95% CI [.19/.58]), family strain (gamma = .38, 95% CI [.19/.58]), and concerns regarding appearance and sexuality (gamma = .31, 95% CI [.14/.47]) than men. Uncertainty (gamma = .18, 95% CI [.12/.24]), appearance and sexuality (gamma = .09, 95% CI [.01/.16]), and health burden (gamma = .21, 95% CI [.14/.27]) emerged as predictors of PTSD symptomatology across the 3 assessment points. CONCLUSIONS: Our data provide first evidence regarding the course of 6 dimensions of CTXD during HSCT and their impact on PTSD symptomatology. Specifically, results emphasize the major burden of uncertainty pre-HSCT and the impact of uncertainty and concerns regarding appearance and sexuality on PTSD symptomatology. PMID- 27718505 TI - Optimization of techniques for multiple platform testing in small, precious samples such as human chorionic villus sampling. AB - BACKGROUND: Multiple testing to understand global changes in gene expression based on genetic and epigenetic modifications is evolving. Chorionic villi, obtained for prenatal testing, is limited, but can be used to understand ongoing human pregnancies. However, optimal storage, processing and utilization of CVS for multiple platform testing have not been established. RESULTS: Leftover CVS samples were flash-frozen or preserved in RNAlater. Modifications to standard isolation kits were performed to isolate quality DNA and RNA from samples as small as 2-5 mg. RNAlater samples had significantly higher RNA yields and quality and were successfully used in microarray and RNA-sequencing (RNA-seq). RNA-seq libraries generated using 200 versus 800-ng RNA showed similar biological coefficients of variation. RNAlater samples had lower DNA yields and quality, which improved by heating the elution buffer to 70 degrees C. Purification of DNA was not necessary for bisulfite-conversion and genome-wide methylation profiling. CVS cells were propagated and continue to express genes found in freshly isolated chorionic villi. CONCLUSIONS: CVS samples preserved in RNAlater are superior. Our optimized techniques provide specimens for genetic, epigenetic and gene expression studies from a single small sample which can be used to develop diagnostics and treatments using a systems biology approach in the prenatal period.

AB - AIM: This study aims to describe the variability of pre-dialysis troponin values in stable haemodialysis patients and compare the performance of single versus fluctuating or persistently elevated troponins in predicting a composite of mortality and cardiac arrest, myocardial infarction or stroke. METHODS: A total of 128 stable ambulatory chronic haemodialysis patients were enrolled. Pre dialysis troponin I was measured for three consecutive months. The patients were followed for 1 year. A troponin elevation (>0.06 MUg/L) was considered high risk, and patients were classified into three risk groups: (i) patients who had normal troponin levels on all three measurements; (ii) patients with at least one elevated and one normal troponin value; and (iii) patients with elevated troponin values on all measurements. RESULTS: A total of 81 patients had all three troponin values in the normal range; 29 had fluctuating values; 18 had all three values elevated. Twenty-seven deaths or composite events were observed: eight in the first risk group, 10 in the second and nine in the third. Persistently elevated and fluctuating troponin values were associated with higher mortality and cardiovascular event rate. Serial troponin measurement had a higher sensitivity for the composite outcome than single troponin measurement when either fluctuating or persistently elevated values were considered to confer high risk. CONCLUSION: Most haemodialysis patients do not have elevated troponin levels at baseline. Troponin levels that remain elevated or fluctuate are associated with worse outcomes. A serial troponin measurement strategy is associated with better sensitivity and higher negative predictive value compared with single troponin measurement. PMID- 27718507 TI - A resting-state fMRI study of obese females between pre- and postprandial states before and after bariatric surgery. AB - Past studies utilizing resting-state functional MRI (rsfMRI), have shown that obese humans exhibit altered activity in brain areas related to reward compared to normal-weight controls. However, to what extent bariatric surgery-induced weight loss alters resting-state brain activity in obese humans is less well studied. Thus, we measured the fractional amplitude of low-frequency fluctuations from eyes-closed, rsfMRI in obese females (n = 11, mean age = 42 years, mean BMI = 41 kg/m2 ) in both a pre- and postprandial state at two time points: four weeks before, and four weeks after bariatric surgery. Several brain areas showed altered resting-state activity following bariatric surgery, including the putamen, insula, cingulate, thalamus and frontal regions. Activity augmented by surgery was also dependent on prandial state. For example, in the fasted state, activity in the middle frontal and pre- and postcentral gyri was found to be decreased after surgery. In the sated state, activity within the insula was increased before, but not after surgery. Collectively, our results suggest that resting-state neural functions are rapidly affected following bariatric surgery and the associated weight loss and change in diet. PMID- 27718508 TI - Psoriasis, fracture risk and bone mineral density: the HUNT Study, Norway. AB - BACKGROUND: An association between psoriasis and osteoporosis has been reported. OBJECTIVES: To investigate, in a large prospective population-based Norwegian study, whether psoriasis is associated with increased risk of forearm or hip fracture; to investigate the cross-sectional association between psoriasis and bone mineral density (BMD) T-score in a subpopulation. METHODS: Hospital-derived fracture data from Nord-Trondelag County (1995-2013) were linked to psoriasis information, BMD measurements and lifestyle factors from the third survey of the Nord-Trondelag Health Study 2006-08 (HUNT3); socioeconomic data from the National Education Database; and use of medication from the Norwegian Prescription Database. RESULTS: Among 48 194 participants in HUNT3, we found no increased risk of forearm or hip fracture in 2804 patients with self-reported psoriasis [overall age- and sex-adjusted hazard ratio 1.03, 95% confidence interval (CI) 0.82-1.31]. No clear association was found between psoriasis and mean BMD T-score; overall age- and sex-adjusted differences in total hip, femoral neck and lumbar spine BMD T-scores were 0.02 (95% CI -0.11 to 0.14), 0.05 (95% CI -0.06 to 0.17) and 0.07 (95% CI -0.09 to 0.24), respectively. No clear association was found between psoriasis and prevalent osteoporosis in either total hip, femoral neck or lumbar spine; overall age- and sex-adjusted odds ratio was 0.77 (95% CI 0.54-1.10). Associations did not change substantially after adjustment for education, smoking, systemic steroid use and body mass index. CONCLUSIONS: We found no association between psoriasis and risk of fracture. The study did not indicate reduced BMD T-score or higher prevalence of osteoporosis among patients with psoriasis. PMID- 27718509 TI - Role of Wnt/beta-catenin pathway in the nucleus accumbens in long-term cocaine induced neuroplasticity: a possible novel target for addiction treatment. AB - Cocaine addiction is a chronic relapsing disorder characterized by the loss of control over drug-seeking and taking, and continued drug use regardless of adverse consequences. Despite years of research, effective treatments for psycho stimulant addiction have not been identified. Persistent vulnerability to relapse arises from a number of long-lasting adaptations in the reward circuitry that mediate the enduring response to the drug. Recently, we reported that the activity of the canonical or Wnt/beta-catenin pathway in the prefrontal cortex (PFC) is very important in the early stages of cocaine-induced neuroadaptations. In the present work, our main goal was to elucidate the relevance of this pathway in cocaine-induced long-term neuroadaptations that may underlie relapse. We found that a cocaine challenge, after a period of abstinence, induced an increase in the activity of the pathway which is revealed as an increase in the total and nuclear levels of beta-catenin (final effector of the pathway) in the nucleus accumbens (NAcc), together with a decrease in the activity of glycogen synthase kinase 3beta (GSK3beta). Moreover, we found that the pharmacological modulation of the activity of the pathway has long-term effects on the cocaine-induced neuroplasticity at behavioral and molecular levels. All the results imply that changes in the Wnt/beta-catenin pathway effectors are long-term neuroadaptations necessary for the behavioral response to cocaine. Even though more research is needed, the present results introduce the Wnt canonical pathway as a possible target to manage cocaine long-term neuroadaptations. PMID- 27718510 TI - Mechanomyographic responses during recruitment curves in the soleus muscle. AB - INTRODUCTION: In this study we examined relationships among mechanomyographic (MMG), electromyographic (EMG), and peak twitch torque (PTT) responses as well as test-retest reliability when recorded during recruitment curves in the soleus muscle. METHODS: PTT, EMG (M-wave, H-reflex), and MMG responses were recorded during recruitment curves in 16 subjects (age 24 +/- 2 years) on 2 separate days. The sum of the M-wave and H-reflex (M+H) was calculated. Correlations among variables and test-retest reliability were determined. RESULTS: MMG was correlated with PTT (mean r = 0.93, range r = 0.59-0.99), the M-wave (0.95, 0.04 0.98), and M+H (0.91, 0.42-0.97), but was unrelated to the H-reflex (-0.06, -0.56 to 0.47). Reliability was consistently high among most variables, but normalizing to the maximum value improved MMG reliability and the minimum detectable change. CONCLUSION: MMG responses predicted 86%-90% of the variability in PTT, M-wave, and M+H; thus, MMG may be a useful alternative for estimating twitch torque and maximal activation.

PMID- 27718511 TI - Oral probiotic treatment of Lactobacillus rhamnosus Lcr35(r) prevents visceral hypersensitivity to a colonic inflammation and an acute psychological stress. AB - AIMS: This study evaluated the efficacy of a repeated oral treatment with two active pharmaceutical ingredients (Lcr Lenio(r) and Lcr Restituo(r) ) derivated from the probiotic bacterial strain Lactobacillus rhamnosus Lcr35(r) in two animal models mimicking different features of irritable bowel syndrome (IBS). IBS is characterized by visceral pain associated with alteration of bowel transit. IBS patients present visceral hypersensitivity with peripheral and central origins. METHODS AND RESULTS: The injection of 2,4,6-trinitrobenzenesulfonic acid (TNBS) into the proximal colon as well as an acute partial restraint stress (PRS) produces colonic hypersensitivity measured in conscious rats by a decrease in pain threshold in response to distal colonic distension. Visceral hypersensitivity was produced by injection of TNBS 7 days before colonic distension or by acute PRS on testing day. Treatments were performed once a day during eight consecutive days. CONCLUSIONS: This study indicates that an 8-day probiotic treatment (Lcr Lenio and Lcr Restituo) produces an antihypersensitivity activity in both TNBS and PRS visceral pain models. As this probiotic strain attenuates peripherally and centrally induced visceral hypersensitivity in rats, it may be active in treatment of IBS symptoms. An immunomodulatory effect of the probiotics was highlighted in the TNBS model on the IL-23 secretion, suggesting a mechanism of action involving a regulation of the local IL-23/Th17 immune activation. SIGNIFICANCE AND IMPACT OF THE STUDY: Two formulas of Lcr35(r) probiotic strain show very encouraging results for the treatment of IBS patients. Further studies are needed to better understand the role and mechanisms of probiotics on the pathogenesis of IBS. PMID- 27718513 TI - Effects of ocean acidification increase embryonic sensitivity to thermal extremes in Atlantic cod, Gadus morhua. AB - Thermal tolerance windows serve as a powerful tool for estimating the vulnerability of marine species and their life stages to increasing temperature means and extremes. However, it remains uncertain to which extent additional drivers, such as ocean acidification, modify organismal responses to temperature. This study investigated the effects of CO2 -driven ocean acidification on embryonic thermal sensitivity and performance in Atlantic cod, Gadus morhua, from the Kattegat. Fertilized eggs were exposed to factorial combinations of two PCO2 conditions (400 MUatm vs. 1100 MUatm) and five temperature treatments (0, 3, 6, 9 and 12 degrees C), which allow identifying both lower and upper thermal tolerance thresholds. We quantified hatching success, oxygen consumption (MO2 ) and mitochondrial functioning of embryos as well as larval morphometrics at hatch and the abundance of acid-base-relevant ionocytes on the yolk sac epithelium of newly hatched larvae. Hatching success was high under ambient spawning conditions (3-6 degrees C), but decreased towards both cold and warm temperature extremes. Elevated PCO2 caused a significant decrease in hatching success, particularly at cold (3 and 0 degrees C) and warm (12 degrees C) temperatures. Warming imposed limitations to MO2 and mitochondrial capacities. Elevated PCO2 stimulated MO2 at cold and intermediate temperatures, but exacerbated warming-induced constraints on MO2 , indicating a synergistic interaction with temperature. Mitochondrial functioning was not affected by PCO2 . Increased MO2 in response to elevated PCO2 was paralleled by reduced larval size at hatch. Finally, ionocyte abundance decreased with increasing temperature, but did not differ between PCO2 treatments. Our results demonstrate increased thermal sensitivity of cod embryos under future PCO2 conditions and suggest that acclimation to elevated PCO2 requires reallocation of limited resources at the expense of embryonic growth. We conclude that ocean acidification constrains the thermal performance window of embryos, which has important implication for the susceptibility of cod to projected climate change. PMID- 27718514 TI - Elevated IL-17A and IL-22 regulate expression of inducible CD38 and Zap-70 in chronic lymphocytic leukemia. AB - BACKGROUND: In this study, we investigated the role and expression of interleukin (IL)-17A and IL-22 in chronic lymphocytic leukemia. METHODS: We evaluated the expression of markers above on CLL by ELISA, qRT-PCR, flow cytometric analysis and nonparametric Kruskal-Wallis test. RESULTS: Quantitative RT-PCR revealed that the mRNA levels of IL-17A and IL-22 in PBMCs of CLL patients were upregulated compared with those from healthy subjects (mean +/- SD: 1.96 +/- 0.232 vs.0.72 +/ 0.15, P < 0.001 and mean +/- SD: 2.45 +/- 0.534 vs.0.81 +/- 0.26, P < 0.001, respectivily). In addition, findings showed that the IL-17A and IL-22 plasma level was significantly elevated than that from healthy control group (P < 0.001). The median IL-17A and IL-22 in CLL patients and healthy control group were 48.28 +/- 17.2 pg mL-1 ; 20.01 +/- 11.16 pg mL-1 and 58.68 +/- 23.4 pg mL-1 ;16.47 +/- 10.31 P < 0.001, respectively. The levels of IL-17A and IL-22 was not significantly associated with the different stages of disease (Rai stages; Kruskal-Wallis test P > 0.05).No significant relationship was found between expression of CD38 and higher median serum levels of IL-17A in patients, but patients with negative expression of ZAP-70 showed a significant association with higher median serum levels of IL-17A compared with healthy subjects. (57.84 pg mL 1 vs. 31.67 pg mL-1 ; P = 0.016). CONCLUSION: IL-22 is elevated and associated with CD38 and Zap-70 expression in patients with CLL. No significant correlation was found between expression of CD38 and increased levels of IL-17A, negative expression of ZAP-70 showed a significant association with increased levels of IL 17A.

PMID- 27718512 TI - Feasibility and tolerability of whole-body, low-intensity vibration and its effects on muscle function and bone in patients with dystrophinopathies: a pilot study. AB - INTRODUCTION: Dystrophinopathies are X-linked muscle degenerative disorders that result in progressive muscle weakness complicated by bone loss. This study's goal was to evaluate feasibility and tolerability of whole-body, low-intensity vibration (WBLIV) and its potential effects on muscle and bone in patients with Duchenne or Becker muscular dystrophy. METHODS: This 12-month pilot study included 5 patients (age 5.9-21.7 years) who used a low-intensity Marodyne LivMD plate vibrating at 30-90 Hz for 10 min/day for the first 6 months. Timed motor function tests, myometry, and peripheral quantitative computed tomography were performed at baseline and at 6 and 12 months. RESULTS: Motor function and lower extremity muscle strength remained either unchanged or improved during the intervention phase, followed by deterioration after WBLIV discontinuation. Indices of bone density and geometry remained stable in the tibia. CONCLUSIONS: WBLIV was well tolerated and appeared to have a stabilizing effect on lower extremity muscle function and bone measures. Muscle Nerve 55: 875-883, 2017. PMID- 27718515 TI - Effect of a general practitioner management plan on health outcomes and hospitalisations in older patients with diabetes. AB - BACKGROUND: Little is known about the impact of a general practitioner management plan (GPMP) on health outcomes of patients with diabetes. AIM: To examine the impact of a GPMP on the risk of hospitalisation for diabetes. METHODS: A retrospective study using administrative data from the Australian Government Department of Veterans' Affairs was conducted (1 July 2006 to 30 June 2014) of diabetes patients either exposed or unexposed to a GPMP. The primary end-point was the risk of first hospitalisation for a diabetes-related complication and was assessed using Cox proportional hazard regression models with death as a competing risk. Secondary end-points included rates of receiving guideline care for diabetes, with differences assessed using Poisson regression analyses. RESULTS: A total of 16 214 patients with diabetes were included; 8091 had a GPMP, and 8123 did not. After 1 year, 545 (6.7%) patients with a GPMP and 634 (7.8%) of patients without a GPMP were hospitalised for a diabetes complication. There was a 22% reduction in the risk of being hospitalised for a diabetes complication (adjusted hazard ratio (HR) 0.78, 95% confidence interval (CI) 0.69-0.87, P < 0.0001) for those who received a GPMP by comparison to those who did not. Increased rates of diabetes guideline care, HbA1c claims (adjusted HR 1.29, 95% CI 1.25-1.33) and microalbuminura claims (adjusted HR 1.65, 95% CI 1.58-1.72) were observed after a GPMP. CONCLUSION: Provision of a GPMP in older patients with diabetes resulted in improved health outcomes, delaying the risk of hospitalisation at 12 months for diabetes complications. GPMP should be included as part of routine primary care for older patients with diabetes. PMID- 27718516 TI - Loss of the arginine methyltranserase PRMT7 causes syndromic intellectual disability with microcephaly and brachydactyly. AB - Post-translational protein modifications exponentially expand the functional complement of proteins encoded by the human genome. One such modification is the covalent addition of a methyl group to arginine or lysine residues, which is used to regulate a substantial proportion of the proteome. Arginine and lysine methylation are catalyzed by protein arginine methyltransferase (PRMTs) and protein lysine methyltransferase proteins (PKMTs), respectively; each methyltransferase has a specific set of target substrates. Here, we report a male with severe intellectual disability, facial dysmorphism, microcephaly, short stature, brachydactyly, cryptorchidism and seizures who was found to have a homozygous 15,309 bp deletion encompassing the transcription start site of PRMT7, which we confirmed is functionally a null allele. We show that the patient's cells have decreased levels of protein arginine methylation, and that affected proteins include the essential histones, H2B and H4. Finally, we demonstrate that patient cells have altered Wnt signaling, which may have contributed to the skeletal abnormalities. Our findings confirm the recent disease association of PRMT7, expand the phenotypic manifestations of this disorder and provide insight into the molecular pathogenesis of this new condition.

AB - BACKGROUND: Insect tolerance to low oxygen (hypoxia) and high carbon dioxide (hypercapnia) is critical for insect control. On the basis of bioassay, metabolism profiles were built to investigate adaptive mechanisms in bean weevil under hypoxia (2% O2 ), hypoxia/hypercapnia (2% O2 + 18% CO2 ) and normoxia (control, 20% O2 + 80% N2 ) using gas chromatography/time-of-flight mass spectrometry (GC/TOF-MS). RESULTS: The growth and development of bean weevils were significantly suppressed by the two hypoxia conditions; hypercapnia enhanced the mortality, but after 24 days of exposure, the surviving insects emerged as adults earlier than those under hypoxia only. Metabolism profiles also showed striking differences in metabolites among the treatment and control groups, both quantitatively and qualitatively. Pairwise comparisons of the three groups showed that 61 metabolites changed significantly, 40 in the hypoxia group and 37 in the hypoxia/hypercapnia group relative to the control group, while only 16 were shared equally by the hypoxia and hypoxia/hypercapnia groups. Increased metabolites were mainly carbohydrates, amino acids and organic acids, while free fatty acids were decreased. Furthermore, the changes were strengthened by the addition of hypercapnia, but excluding free fatty acids. CONCLUSION: The findings show that bean weevil has high tolerance to hypoxia or even hypoxia/hypercapnia at biologically achievable levels and provide more direct evidence for stored product insect mechanism regulation under hypoxia stress, especially free fatty acid regulation by hypercapnia but not by hypoxia.

AB - The HAS-BLED model is widely utilized to assess patients' bleed risk prior to anticoagulant therapy including warfarin. Some of the variables assessed in the model are also known to influence warfarin control, commonly measured by time in therapeutic range (TTR). The aim of the study was to determine whether the HAS BLED risk tool is a good predictor of bleed risk and warfarin control in deep vein thrombosis (DVT) patients. Retrospective data were collected for DVT warfarin care patients at Sullivan Nicolaides Pathology. Data included age, medical history and concurrent drug therapy to calculate HAS-BLED scores. INR results were used to calculate TTR with the Rosendaal method and mean TTR used for analysis and comparison. The eligible 533 patients had a mean TTR of 78.3%. Categorization according to HAS-BLED score resulted in 150 patients classified as low-risk, 331 as moderate-risk and 52 as high-risk with a haemorrhagic incidence per patient of 0.08, 0.53 and 0.54, respectively. Patients in the low-, moderate- and high-risk HAS-BLED categories had a mean TTR of 81%, 79% and 65%, respectively, with significant differences (p < 0.001) found in TTR between the low- and high-risk and moderate- and high-risk categories. In an Australian DVT population, the HAS-BLED score accurately predicts decreasing warfarin control with increasing risk category, and patients with scores >=3 achieve poor control as indicated by a TTR <70%. In addition to predicting bleed risk, the HAS-BLED tool may also predict the potential benefit of warfarin treatment and hence influence choice of anticoagulant therapy. PMID- 27718520 TI - Detecting pyrethroid resistance in predatory mites inhabiting soil and litter: an in vitro test. AB - BACKGROUND: While resistance against insecticides is widely known in pest arthropods, it remains poorly known in non-target arthropods of the same agrosystems. This may be of crucial importance in the context of organic pest management or integrated pest management. First, stopping of pesticide pressure during farm conversion may lead to important rearrangements of non-target communities due to fitness cost of resistance in populations of some species. Second, resistant biological agents may be useful to farms with low synthetic pesticide use. Communities of mesostigmatid mites, encompassing numerous predatory species, are supposed to be involved in important ecological processes in both crop soils and animal litter/manure. RESULTS: Here we provide a tarsal contact method for assessing resistance in different populations from various species of mesostigmatid mites. Analyses of data from repeated tests on three populations from different mesostigmatid families proved the method to be robust and able to generate consistent and reliable mortality percentages according to insecticide concentration. CONCLUSION: Our bioassay system allows for both one shot estimate of pyrethroid sensitivity in mite populations and estimation of how it changes over time, making possible survival analyses and assessment of recovery from knockdown. The rating system retained makes it possible to score response to insecticides in a consistent and standard way in species from different mesostigmatid families.

AB - BACKGROUND: Rosacea is currently diagnosed by consensus-defined primary and secondary features and managed by subtype. However, individual features (phenotypes) can span multiple subtypes, which has implications for clinical practice and research. Adopting a phenotype-led approach may facilitate patient centred management. OBJECTIVES: To advance clinical practice by obtaining international consensus to establish a phenotype-led rosacea diagnosis and classification scheme with global representation. METHODS: Seventeen dermatologists and three ophthalmologists used a modified Delphi approach to reach consensus on statements pertaining to critical aspects of rosacea diagnosis, classification and severity evaluation. All voting was electronic and blinded. RESULTS: Consensus was achieved for transitioning to a phenotype-based approach to rosacea diagnosis and classification. The following two features were independently considered diagnostic for rosacea: (i) persistent, centrofacial erythema associated with periodic intensification; and (ii) phymatous changes. Flushing, telangiectasia, inflammatory lesions and ocular manifestations were not considered to be individually diagnostic. The panel reached agreement on dimensions for phenotype severity measures and established the importance of assessing the patient burden of rosacea. CONCLUSIONS: The panel recommended an approach for diagnosis and classification of rosacea based on disease phenotype. PMID- 27718521 TI - Validation of the Simplified Psoriasis Index in Dutch children and adolescents with plaque psoriasis. AB - BACKGROUND: The Simplified Psoriasis Index (SPI) is a three-domain assessment measure for psoriasis, including separate indicators of current severity (SPI-s), psychosocial impact (SPI-p), and past history and interventions (SPI-i). There are two complementary versions available designed for completion by a health professional (proSPI) or by patient self-assessment (saSPI). The validity and reliability of the proSPI vs. saSPI have already been demonstrated in adults. To date, validated severity measures for paediatric psoriasis do not exist. OBJECTIVES: To validate the current severity (SPI-s) and psychosocial impact (SPI p) domains of the proSPI and saSPI in children and adolescents with psoriasis. METHODS: All patients aged < 18 years with plaque psoriasis visiting the dermatology outpatient department of Radboud University Medical Center, the Netherlands, between September 2013 and April 2014 were asked to complete Dutch versions of the saSPI and the Children's Dermatology Life Quality Index (CDLQI). The original English versions of the proSPI and Psoriasis Area and Severity Index (PASI) were completed by the physician at the same visit. RESULTS: In total, 113 patients (median age 12.0 years, range 4-17) were included. There was a close correlation between the proSPI-s and PASI (r = 0.87), which was higher than between the saSPI-s and PASI (r = 0.69). The correlation between the SPI-p and CDLQI was 0.78. The full range of scores was utilized in both proSPI-s and SPI-p, although the highest saSPI-s score was 30 (maximum 50). CONCLUSIONS: In paediatric psoriasis, the proSPI and saSPI are shown to be valid and usable. The SPI-s and SPI-p can be readily introduced into routine clinical practice.

PMID- 27718524 TI - Antisense locked nucleic acids targeting agrA inhibit quorum sensing and pathogenesis of community-associated methicillin-resistant Staphylococcus aureus. AB - AIM: Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is commonly associated with nonnosocomial skin and soft tissue infections due to its virulence, which is mainly controlled by the accessory gene regulator (agr) quorum sensing (QS) system. In this study (KFF)3 K peptide-conjugated locked nucleic acids (PLNAs) targeting agrA mRNA were developed to inhibit agr activity and arrest the pathogenicity of CA-MRSA. METHODS AND RESULTS: Two PLNAs were designed, and synthesized, after predicting the secondary structure of agrA mRNA. The influence on bacterial growth was tested using a growth curve assay. RT-qPCR, haemolysis assay, lactate dehydrogenase release assay and chemotaxis assay were used to evaluate the effects of the PLNAs on inhibiting agr QS. A mouse skin infection model was employed to test the protective effect of the PLNAs in vivo. None of the PLNAs were found to be bacteriostatic or bactericidal in vitro. However, one PLNA, PLNA34, showed strong ability to suppress expression of agrA and the effector molecule RNAIII in USA300 LAC strain. Furthermore, PLNA34 inhibited the expression of virulence genes that are upregulated by agr, including hla, psmalpha, psmbeta and pvl. The haemolytic activity of the supernatants from PLNA34-treated bacteria was also dramatically reduced, as well as the capacity to lyse and recruit neutrophils. Moreover, PLNA34 showed high levels of protection in the CA-MRSA mouse skin infection model. CONCLUSIONS: The anti-agrA PLNA34 can effectively inhibit the agr QS and suppress CA-MRSA pathogenicity. SIGNIFICANCE AND IMPACT OF THE STUDY: agrA is a promising target for the development of antisense oligonucleotides to block agr QS.

PMID- 27718526 TI - Multimorbidity patterns of oral clinical conditions, social position, and oral health-related quality of life in a population-based survey of 12-yr-old children. AB - The aim of this study was to describe the patterns of multimorbidities of oral clinical conditions in children. The association between social position and number of oral clinical conditions, and the relationship of social position and number of oral clinical conditions with oral health-related quality of life [OHRQoL, measured using the Brazilian Child-Oral Impacts on Daily Performance (Child-OIDP)] were also investigated. The study analysed data on 7,208 children, 12 yr of age, from the Brazilian Oral Health Survey (SBBrasil Project). Cluster analysis based on the observed/expected (O/E) ratios identified six significant clusters of oral clinical conditions: (i) dental caries and missing teeth; (ii) dental caries and dental trauma; (iii) dental trauma and gingivitis; (iv) dental caries, missing teeth, and dental trauma; (v) dental caries, dental trauma, and gingivitis; and (vi) all oral clinical conditions. Ordinal regression showed that poor social position was associated with a large number of oral clinical conditions. Poisson regression demonstrated that low social position and greater number of oral clinical conditions increased the likelihood of poor OHRQoL (Child OIDP extent). The four oral clinical conditions clustered into six distinct clusters among Brazilian children. Multimorbidity of oral clinical conditions predicted poor OHRQoL. Social position was of high relevance to multimorbidity of oral clinical conditions and children's OHRQoL. PMID- 27718527 TI - A descriptive survey of cancer helplines in the United Kingdom: Who they are, the services offered, and the accessibility of those services. AB - BACKGROUND: There are more than 1500 UK health helplines in operation, yet we have scant knowledge about the resources in place to support the seeking and delivering of cancer-related telephone help and support. This research aimed to identify and describe cancer and cancer-related helpline service provision: the number of helplines available, the variety of services provided, and the accessibility of those services. METHOD: This study used online national questionnaire survey sent to 95 cancer and cancer-related helplines in the United Kingdom. RESULTS: A total of 69 (73%) of 95 surveyed cancer and cancer-related helplines completed the survey. Most helplines/organizations were registered charities, supported by donations; 73.5% of helplines had national coverage. Most helplines served all age-groups, ethnic groups, and men and women. Only 13.4% had a number that was free from landlines and most mobile networks, and 56.6% could only be contacted during working hours. More than 50% of helplines reported no provisions for callers with additional needs, and 55% had no clinical staff available to callers. Ongoing support and training for helpline staff was available but variable. CONCLUSION: Although cancer helplines in the United Kingdom offer reasonably broad coverage across the country, there are still potential barriers to accessibility. There are also opportunities to optimize the training of staff/volunteers across the sector. There are further prospects for helplines to enhance services and sustain appropriate and realistic quality standards. PMID- 27718528 TI - Childhood body mass index growth trajectories and endometrial cancer risk. AB - Previously, we found that excess weight already in childhood has positive associations with endometrial cancer; however, associations with changes in body mass index (BMI) during childhood are not well understood. Therefore, we examined whether growth in childhood BMI is associated with endometrial cancer and its sub types. A cohort of 155,505 girls from the Copenhagen School Health Records Register with measured weights and heights at the ages of 6-14 years and born 1930-1989 formed the analytical population. BMI was transformed to age-specific z scores. Using linear spline multilevel models, each girl's BMI growth trajectory was estimated as the deviance from the average trajectory for three different growth periods (6.25-7.99, 8.0-10.99, 11.0-14.0 years). Via a link to health registers, 1,020 endometrial cancer cases were identified, and Cox regressions were performed. A greater gain in BMI during childhood was positively associated with endometrial cancer but no differences between the different growth periods were detected in models adjusted for baseline BMI. The hazard ratios for the associations with overall growth during childhood per 0.1 z score increase were 1.15 (95% confidence interval [CI]: 1.07-1.24) for all endometrial cancers, 1.12 (95% CI: 1.04-1.21) for estrogen-dependent cancers, 1.16 (95% CI: 1.06-1.26) for endometrioid adenocarcinomas and 1.46 (95% CI: 1.16-1.84) for non-estrogen dependent cancers. Growth in BMI in early life is positively linked to later endometrial cancer risk. We did not identify any sensitive childhood growth period, which suggests that excess gain in BMI during the entire childhood period should be avoided.

This case offers further insights into the possible pathogenesis of blepharochalasis, paving the way for more targeted, disease-modifying therapies. PMID- 27718530 TI - Anti-angiogenic potential of VEGF blocker dendron loaded on to gellan gum hydrogels for tissue engineering applications. AB - Damage of non-vascularised tissues such as cartilage and cornea can result in healing processes accompanied by a non-physiological angiogenesis. Peptidic aptamers have recently been reported to block the vascular endothelial growth factor (VEGF). However, the therapeutic applications of these aptamers are limited due to their short half-life in vivo. In this work, an enhanced stability and bioavailability of a known VEGF blocker aptamer sequence (WHLPFKC) was pursued through its tethering of molecular scaffolds based on hyperbranched peptides, the poly(E-lysine) dendrons, bearing three branching generations. The proposed design allowed simultaneous and orderly-spaced exposure of 16 aptamers per dendrimer to the surrounding biological microenvironent, as well as a relatively hydrophobic core based on di-phenylalanine aiming to promote an hydrophobic interaction with the hydrophobic moieties of ionically crosslinked methacrylated gellan gum (iGG-MA) hydrogels. The VEGF blocker dendrons were entrapped in iGG-MA hydrogels, and their capacity to prevent endothelial cell sprouting was assessed qualitatively and quantitatively using 3D in vitro models and the in vivo chick chorioallantoic membrane assay. The data demonstrate that at nanoscale concentrations, the dendronised structures were able to enhance control of the biological actvity of WHLPFKC at the material/tissue interface and hence the anti-angiogenic capacity of iGG-MA hydrogels not only preventing blood vessel invasion, but also inducing their regression at the tissue/iGG-MA interface. The in ovo study confirmed that iGG-MA functionalised with the dendron VEGF blockers do inhibit angiogenesis by controlling both size and ramifications of blood vessels in the proximity of the implanted gel surface.

AB - Urban environments are warmer, have higher levels of atmospheric CO2 and have altered patterns of disturbance and precipitation than nearby rural areas. These differences can be important for plant growth and are likely to create distinct selective environments. We planted a common garden experiment with seeds collected from natural populations of the native annual plant Lepidium virginicum, growing in five urban and nearby rural areas in the northern United States to determine whether and how urban populations differ from those from surrounding rural areas. When grown in a common environment, plants grown from seeds collected from urban areas bolted sooner, grew larger, had fewer leaves, had an extended time between bolting and flowering, and produced more seeds than plants grown from seeds collected from rural areas. Interestingly, the rural populations exhibited larger phenotypic differences from one another than urban populations. Surprisingly, genomic data revealed that the majority of individuals in each of the urban populations were more closely related to individuals from other urban populations than they were to geographically proximate rural areas - the one exception being urban and rural populations from New York which were nearly identical. Taken together, our results suggest that selection in urban environments favors different traits than selection in rural environments and that these differences can drive adaptation and shape population structure. PMID- 27718534 TI - Cargo rigidity affects the sensitivity of dynein ensembles to individual motor pausing. AB - Cytoplasmic dynein is a minus-end directed microtubule-based motor protein that drives intracellular cargo transport in eukaryotic cells. Although many intracellular cargos are propelled by small groups of dynein motors, the biophysical mechanisms governing ensemble motility remain largely unknown. To investigate the emergent motility of motor ensembles, we have designed a programmable DNA origami synthetic cargo "chassis" enabling us to control the number of dynein motors in the ensemble and vary the rigidity of the cargo chassis itself. Using total internal reflection fluorescence microscopy, we have observed dynein ensembles transporting these cargo chassis along microtubules in vitro. We find that ensemble motility depends on cargo rigidity: as the number of motors increases, ensembles transporting flexible cargos move comparatively faster than a single motor, whereas ensembles transporting rigid cargos move slower than a single motor. To explain this, we show that ensembles connected through flexible cargos are less sensitive to the pauses of individual motors within the ensemble. We conclude that cargo rigidity plays an important role in communicating and coordinating the states of motors, and consequently in the subsequent mechanisms of collective motility. The insensitivity of ensemble driven cargos to the pausing of individual motors may contribute to the robustness and versatility of intracellular cargo transport. (c) 2016 Wiley Periodicals, Inc. PMID- 27718532 TI - Identification of miRSNPs associated with the risk of multiple myeloma. AB - Multiple myeloma (MM) is a malignancy of plasma cells usually infiltrating the bone marrow, associated with the production of a monoclonal immunoglobulin (M protein) which can be detected in the blood and/or urine. Multiple lines of evidence suggest that genetic factors are involved in MM pathogenesis, and several studies have identified single nucleotide polymorphisms (SNPs) associated with the susceptibility to the disease. SNPs within miRNA-binding sites in target genes (miRSNPs) may alter the strength of miRNA-mRNA interactions, thus deregulating protein expression. MiRSNPs are known to be associated with risk of various types of cancer, but they have never been investigated in MM. We performed an in silico genome-wide search for miRSNPs predicted to alter binding of miRNAs to their target sequences. We selected 12 miRSNPs and tested their association with MM risk. Our study population consisted of 1,832 controls and 2,894 MM cases recruited from seven European countries and Israel in the context of the IMMEnSE (International Multiple Myeloma rESEarch) consortium. In this population two SNPs showed an association with p < 0.05: rs286595 (located in gene MRLP22) and rs14191881 (located in gene TCF19). Results from IMMEnSE were meta-analyzed with data from a previously published genome-wide association study (GWAS). The SNPs rs13409 (located in the 3'UTR of the POU5F1 gene), rs1419881 (TCF19), rs1049633, rs1049623 (both in DDR1) showed significant associations with MM risk. In conclusion, we sought to identify genetic polymorphisms associated with MM risk starting from genome-wide prediction of miRSNPs. For some mirSNPs, we have shown promising associations with MM risk. PMID- 27718533 TI - Improving anxiety regulation in patients with breast cancer at the beginning of the survivorship period: a randomized clinical trial comparing the benefits of single-component and multiple-component group interventions. AB - OBJECTIVE: To compare in a multicenter randomized controlled trial the benefits in terms of anxiety regulation of a 15-session single-component group intervention (SGI) based on support with those of a 15-session multiple-component structured manualized group intervention (MGI) combining support with cognitive behavioral and hypnosis components. METHODS: Patients with nonmetastatic breast cancer were randomly assigned at the beginning of the survivorship period to the SGI (n = 83) or MGI (n = 87). Anxiety regulation was assessed, before and after group interventions, through an anxiety regulation task designed to assess their ability to regulate anxiety psychologically (anxiety levels) and physiologically (heart rates). Questionnaires were used to assess psychological distress, everyday anxiety regulation, and fear of recurrence. Group allocation was computer generated and concealed till baseline completion. RESULTS: Compared with patients in the SGI group (n = 77), patients attending the MGI group (n = 82) showed significantly reduced anxiety after a self-relaxation exercise (P = .006) and after exposure to anxiety triggers (P = .013) and reduced heart rates at different time points throughout the task (P = .001 to P = .047). The MGI participants also reported better everyday anxiety regulation (P = .005), greater use of fear of recurrence-related coping strategies (P = .022), and greater reduction in fear of recurrence-related psychological distress (P = .017) compared with the SGI group. CONCLUSIONS: This study shows that an MGI combining support with cognitive-behavioral techniques and hypnosis is more effective than an SGI based only on support in improving anxiety regulation in patients with breast cancer. PMID- 27718535 TI - The rhythm of the executive gate of speech: subthalamic low-frequency oscillations increase during verbal generation. AB - We investigated neurophysiological mechanisms of subthalamic nucleus involvement in verbal fluency through a verbal generation task. The subthalamic nucleus is thought to act as a behavioural go/no-go instance by means of oscillatory communication in the theta band with the prefrontal cortex. Because subthalamic alpha-theta frequency stimulation has been shown to exert beneficial effects on verbal fluency in Parkinson's disease, we hypothesized that an alpha-theta oscillatory network involving the subthalamic nucleus underlies verbal generation task performance as a gating instance for speech execution. Postoperative subthalamic local field potential recordings were performed during a verbal generation compared to a control task. Time-frequency analysis revealed a significant alpha-theta power increase and enhanced alpha-theta coherence between the subthalamic nucleus and the frontal surface EEG during the verbal generation task. Beta and gamma oscillations were not significantly modulated by the task. Power increase significantly correlated with verbal generation performance. Our results provide experimental evidence for local alpha-theta oscillatory activity in the subthalamic nucleus and coherence to frontal associative areas as a neurophysiological mechanism underlying a verbal generation task. Thus, verbal fluency improvement during subthalamic alpha-theta stimulation in Parkinson's disease is likely due to an enhancement of alpha-theta oscillatory network activity. Alpha-theta oscillations can be interpreted as the rhythmic gating signature in a speech executing subthalamic-prefrontal network. PMID- 27718536 TI - Encoding of global visual motion in the nidopallium caudolaterale of behaving crows. AB - Songbirds possess acute vision. How higher brain centres represent basic and parameterised visual stimuli to process sensory signals according to their behavioural importance has not been studied in a systematic way. We therefore examined how carrion crows (Corvus corone) and their nidopallial visual neurons process global visual motion information in dynamic random-dot displays during a delayed match-to-sample (DMS) task. The behavioural data show that moderately fast motion speeds (16 degrees of visual angle/s) result in superior direction discrimination performance. To characterise how neurons encode and maintain task relevant visual motion information, we recorded the single-unit activity in the telencephalic association area 'nidopallium caudolaterale' (NCL) of behaving crows. The NCL is considered to be the avian analogue of the mammalian prefrontal cortex. Almost a third (28%) of randomly selected NCL neurons responded selectively to the motion direction of the sample stimulus, mostly to downward motions. Only few NCL neurons (7.5%) responded consistently to specific motion directions during the delay period. In error trials, when the crows chose the wrong motion direction, the encoding of motion direction was significantly reduced. This indicates that sensory representations of NCL neurons are relevant to the birds' behaviour. These data suggest that the corvid NCL, even though operating at the apex of the telencephalic processing hierarchy, constitutes a telencephalic site for global motion integration. PMID- 27718538 TI - Pregnancy as a driver for melanoma. AB - Whether or not pregnancy favours the occurrence and growth of melanoma is a source of controversy in the literature. Several case reports have shown dramatic courses of diseases in pregnancy. We present a case of a 36-year-old woman with multiple naevi with one melanoma detected in 2009 in the first trimester and a second primary melanoma in 2010 in the third trimester of her pregnancy. Both lesions have been present for at least 5 years and have been interpreted as dysplastic naevi. Because of their growth during pregnancy they were removed. No metastatic disease has been found between 2010 and early 2017. This case shows the difficulty of detecting melanomas in pregnancy, particularly when they mimic dysplastic naevi in women with multiple naevi, who are at higher risk. Therefore, we suggest that pregnant women with numerous naevi should be precautious of any changes of their naevi in size, shape and colour. Every suspicious lesion should be either excised or documented/monitored carefully, for example with sequential digital dermoscopy imaging. PMID- 27718537 TI - Adaptive dynamics of cuticular hydrocarbons in Drosophila. AB - Cuticular hydrocarbons (CHCs) are hydrophobic compounds deposited on the arthropod cuticle that are of functional significance with respect to stress tolerance, social interactions and mating dynamics. We characterized CHC profiles in natural populations of Drosophila melanogaster at five levels: across a latitudinal transect in the eastern United States, as a function of developmental temperature during culture, across seasonal time in replicate years, and as a function of rapid evolution in experimental mesocosms in the field. Furthermore, we also characterized spatial and temporal changes in allele frequencies for SNPs in genes that are associated with the production and chemical profile of CHCs. Our data demonstrate a striking degree of parallelism for clinal and seasonal variation in CHCs in this taxon; CHC profiles also demonstrate significant plasticity in response to rearing temperature, and the observed patterns of plasticity parallel the spatiotemporal patterns observed in nature. We find that these congruent shifts in CHC profiles across time and space are also mirrored by predictable shifts in allele frequencies at SNPs associated with CHC chain length. Finally, we observed rapid and predictable evolution of CHC profiles in experimental mesocosms in the field. Together, these data strongly suggest that CHC profiles respond rapidly and adaptively to environmental parameters that covary with latitude and season, and that this response reflects the process of local adaptation in natural populations of D. melanogaster. PMID- 27718539 TI - Effective cancer targeting and imaging using macrophage membrane-camouflaged upconversion nanoparticles. AB - Upconversion nanoparticles (UCNPs), with fascinating optical and chemical features, are a promising new generation of fluorescent probes. Although UCNPs have been widely used in diagnosis and therapy, there is an unmet need for a simple and effective surface engineering method that can produce cancer-targeting UCNPs. Here, we show that by coating particles with macrophage membranes, it becomes possible to utilize the adhesion between macrophages and cancer cells for effective cancer targeting. Natural macrophage membranes along with their associated membrane proteins were reconstructed into vesicles and then coated onto synthetic UCNPs. The resulting macrophage membrane-camouflaged particles (MM UCNPs) exhibited effective cancer targeting capability inherited from the source cells and were further used for enhanced in vivo cancer imaging. Finally, the blood biochemistry, hematology testing and histology analysis results suggested a good in vivo biocompatibility of MM-UCNPs. The combination of synthetic nanoparticles with biomimetic cell membranes embodies a novel design strategy toward developing biocompatible nanoprobes for potential clinical applications.

PMID- 27718542 TI - Dry-Processed, Binder-Free Holey Graphene Electrodes for Supercapacitors with Ultrahigh Areal Loadings. AB - For commercial applications, the need for smaller footprint energy storage devices requires more energy to be stored per unit area. Carbon nanomaterials, especially graphene, have been studied as supercapacitor electrodes and can achieve high gravimetric capacities affording high gravimetric energy densities. However, most nanocarbon-based electrodes exhibit a significant decrease in their areal capacitances when scaled to the high mass loadings typically used in commercially available cells (~10 mg/cm2). One of the reasons for this behavior is that the additional surface area in thick electrodes is not readily accessible by electrolyte ions due to the large tortuosity. Furthermore, the fabrication of such electrodes often involves complicated processes that limit the potential for mass production. Here, holey graphene electrodes for supercapacitors that are scalable in both production and areal capacitance are presented. The lateral surface porosity on the graphene sheets was created using a facile single-step air oxidation method, and the resultant holey graphene was compacted under ambient conditions into mechanically robust monolithic shapes that can be directly used as binder-free electrodes. In comparison, pristine graphene discs under similar binder-free compression molding conditions were extremely brittle and thus not deemed useful for electrode applications. The coin cell supercapacitors, based on these holey graphene electrodes exhibited small variations in gravimetric capacitance over a wide range of areal mass loadings (~1-30 mg/cm2) at current densities as high as 30 mA/cm2, resulting in the near linear increase of the areal capacitance (F/cm2) with the mass loading. The prospects of the presented method for facile binder-free ultrathick graphene electrode fabrication are discussed. PMID- 27718541 TI - Trafficking of adeno-associated virus vectors across a model of the blood-brain barrier; a comparative study of transcytosis and transduction using primary human brain endothelial cells. AB - Developing therapies for central nervous system (CNS) diseases is exceedingly difficult because of the blood-brain barrier (BBB). Notably, emerging technologies may provide promising new options for the treatment of CNS disorders. Adeno-associated virus serotype 9 (AAV9) has been shown to transduce cells in the CNS following intravascular administration in rodents, cats, pigs, and non-human primates. These results suggest that AAV9 is capable of crossing the BBB. However, mechanisms that govern AAV9 transendothelial trafficking at the BBB remain unknown. Furthermore, possibilities that AAV9 may transduce brain endothelial cells or affect BBB integrity still require investigation. Using primary human brain microvascular endothelial cells as a model of the human BBB, we performed transduction and transendothelial trafficking assays comparing AAV9 to AAV2, a serotype that does not cross the BBB or transduce endothelial cells effectively in vivo. Results of our in vitro studies indicate that AAV9 penetrates brain microvascular endothelial cells barriers more effectively than AAV2, but has reduced transduction efficiency. In addition, our data suggest that (i) AAV9 penetrates endothelial barriers through an active, cell-mediated process, and (ii) AAV9 fails to disrupt indicators of BBB integrity such as transendothelial electrical resistance, tight junction protein expression/localization, and inflammatory activation status. Overall, this report shows how human brain endothelial cells configured in BBB models can be utilized for evaluating transendothelial movement and transduction kinetics of various AAV capsids. Importantly, the use of a human in vitro BBB model can provide import insight into the possible effects that candidate AVV gene therapy vectors may have on the status of BBB integrity.

Here, a hybrid material is reported, in which tungsten carbide (WC) and ferberite (FeWO4) are attached to the Fe and N dual-doped ordered mesoporous carbon (WC-FeWO4@FeN-OMC) as a superior performance catalyst for the ORR in either acidic or basic media. In comparison with the frequently used Pt/C ORR catalyst (20 wt. %), our hybrid materials exhibit comparable electrocatalytic activity mainly via a 4e ORR process, better stability, and total tolerance to methanol in either acidic or basic media. These advantages, especially the outstanding stability in acidic media, render the WC-FeWO4@FeN-OMC as a promising potential non-precious-metal ORR catalyst in practical fuel cell applications.

Familial UM (FUM), defined as two or more family members diagnosed with UM, is rare and estimated at less than 1% of all UM. Currently, BAP1 is the only gene known to contribute significant risk for UM. In this study we aimed to estimate the frequency of BAP1 mutation in FUM and to characterize the family and personal histories of other cancers in these families. We identified 32 families with FUM, including seven families previously reported by our group. BAP1 mutation testing was carried out by direct sequencing of the coding exons and the adjacent untranslated regions of the gene. Germline deletion and duplication analysis of BAP1 was assessed by multiplex ligation-dependent probe amplification (MLPA). Germline BAP1 mutations were found in 6/32 (19%) families. No deletions or duplications were identified in any of the 24 samples tested by MLPA. Combined with published studies, the frequency of BAP1 mutations was 14/64 (22%) in FUM. FUM families without BAP1 mutations have distinct family histories with high rates of prostate cancer in first- and second-degree relatives. It is likely that additional genes conferring risk for FUM exist. It is important to understand key shared features of FUM to focus future research on identifying these additional tumor predisposition syndromes. Though BAP1 should be tested first in these families, FUM families without BAP1 mutation should be explored for additional predisposition genes. (c) 2016 Wiley Periodicals, Inc.

By using engineered processes to control the mixing, chemical energy stored in salinity gradients can be harnessed for useful work. In this critical review, we present an overview of the current progress in salinity gradient power generation, discuss the prospects and challenges of the foremost technologies - pressure retarded osmosis (PRO), reverse electrodialysis (RED), and capacitive mixing (CapMix) and provide perspectives on the outlook of salinity gradient power generation. Momentous strides have been made in technical development of salinity gradient technologies and field demonstrations with natural and anthropogenic salinity gradients (for example, seawater-river water and desalination brine-wastewater, respectively), but fouling persists to be a pivotal operational challenge that can significantly ebb away cost competitiveness. Natural hypersaline sources (e.g., hypersaline lakes and salt domes) can achieve greater concentration difference and, thus, offer opportunities to overcome some of the limitations inherent to seawater-river water. Technological advances needed to fully exploit the larger salinity gradients are identified. While seawater desalination brine is a seemingly attractive high salinity anthropogenic stream that is otherwise wasted, actual feasibility hinges on the appropriate pairing with a suitable low salinity stream. Engineered solutions are foulant-free and can be thermally regenerative for application in low-temperature heat utilization. Alternatively, PRO, RED, and CapMix can be coupled with their analog separation process (reverse osmosis, electrodialysis, and capacitive deionization, respectively) in salinity gradient flow batteries for energy storage in chemical potential of the engineered solutions. Rigorous techno-economic assessments can more clearly identify the prospects of low-grade heat conversion and large-scale energy storage. While research attention is squarely focused on efficiency and power improvements, efforts to mitigate fouling and lower membrane and electrode cost will be equally important to reduce levelized cost of salinity gradient energy production and, thus, boost PRO, RED, and CapMix power generation to be competitive with other renewable technologies. Cognizance of the recent key developments and technical progress on the different technological fronts can help steer the strategic advancement of salinity gradient as a sustainable energy source.

AB - Strong visible light absorption and high charge mobility are desirable properties for an efficient photocatalyst, yet they are hard to be realized simultaneously in a single semiconductor compound. In this work, we demonstrate that these properties coexist in homologous compounds ZnnIn2O3+n (n = 4, 5, and 7) with a peculiar layered structure that combines optical active segment and electrical conductive segment together. Their enhanced visible light absorption originates from tetrahedrally or trigonal-bipyramidally coordinated In atoms in Zn(In)O4(5) layers which enable p-d hybridization between In 4d and O 2p orbitals so that valence band minimum (VBM) is uplifted with a reduced band gap. Theoretical calculations reveal their anisotropic features in charge transport and functionality of different constituent segments, i.e., Zn(In)O4(5) layers and InO6 layers as being for charge generation and charge collection, respectively. Efficient photocatalytic hydrogen evolution was observed in these compounds under full range (lambda >= 250 nm) and visible light irradiation (lambda >= 420 nm). High apparent quantum efficiency ~2.79% was achieved for Zn4In2O7 under full range irradiation, which is almost 5-fold higher than their parent oxides ZnO and In2O3. Such superior photocatalytic activities of these homologous compounds can be understood as layer-by-layer packing of charge generation/collection functional groups that ensures efficient photocatalytic reactions.

AB - The PC12 cell line is a widely used in vitro model for screening the neuroprotective activity of small molecule libraries. External insult due to serum deprivation or addition of etoposide induces cell death by apoptosis. While this screening method is commonly used in early stage drug discovery no protocol accounting for cell passage number effect on neuroprotective activity has been disclosed. We herein report that passage variation results in false positive/false-negative identification of neuroprotective compounds; undifferentiated PC12 cells with high passage number are less sensitive to injury induced by serum-deprivation or etoposide treatment. In contrast, NGF differentiated PC12 cells of later passage number are more sensitive to injury induced by etoposide than lower passage number but only after 72 h. Passage number also affects the adherence phenotype of the PC12 cells, complicating screening assays. We report an optimized protocol for screening the neuroprotective activity of small molecules in PC12 cells, which accounts for passage number variations.

AB - We describe the application of photodetachable and recyclable dispersants for single-walled carbon nanotubes (SWNTs) in the fabrication of photopatterned SWNT thin films. Because adsorption and desorption of the dispersants on the SWNT surfaces affect not only their dispersibility in water but also their solubility, SWNT photopatterns were obtained on glass substrates in only three steps, i.e., casting the SWNT/dispersant solution, UV-light exposure of the casted SWNT/dispersant films through a photomask, and subsequent rinsing with neutral water. This patterning procedure is simple and scalable and will enable us to prepare microfabricated SWNT thin films. PMID- 27718548 TI - Isomeric Sc2O@C78 Related by a Single-Step Stone-Wales Transformation: Key Links in an Unprecedented Fullerene Formation Pathway. AB - It has been proposed that the fullerene formation mechanism involves either a top down or bottom-up pathway. Despite different starting points, both mechanisms approve that particular fullerenes or metallofullerenes are formed through a consecutive stepwise process involving Stone-Wales transformations (SWTs) and C2 losses or additions. However, the formation pathway has seldomly been defined at the atomic level due to the missing-link fullerenes. Herein, we present the isolation and crystallographic characterization of two isomeric clusterfullerenes Sc2O@C2v(3)-C78 and Sc2O@D3h(5)-C78, which are closely related via a single-step Stone-Wales (SW) transformation. More importantly, these novel Sc2O@C78 isomers represent the key links in a well-defined formation pathway for the majority of solvent-extractable clusterfullerenes Sc2O@C2n (n = 38-41), providing molecular structural evidence for the less confirmed fullerene formation mechanism. Furthermore, DFT calculations reveal a SWT with a notably low activation barrier for these Sc2O@C78 isomers, which may rationalize the established fullerene formation pathway. Additional characterizations demonstrate that these Sc2O@C78 isomers feature different energy bandgaps and electrochemical behaviors, indicating the impact of SW defects on the energetic and electrochemical characteristics of metallofullerenes.

AB - Potassium is an earth abundant alternative to lithium for rechargeable batteries, but a critical limitation in potassium ion battery anodes is the low capacity of KC8 graphite intercalation compounds in comparison to conventional LiC6. Here we demonstrate that nitrogen doping of few-layered graphene can increase the storage capacity of potassium from a theoretical maximum of 278 mAh/g in graphite to over 350 mAh/g, competitive with anode capacity in commercial lithium-ion batteries and the highest reported anode capacity so far for potassium ion batteries. Control studies distinguish the importance of nitrogen dopant sites as opposed to sp3 carbon defect sites to achieve the improved performance, which also enables > 6X increase in rate performance of doped versus undoped materials. Finally, in situ Raman spectroscopy studies elucidate the staging sequence for doped and undoped materials and demonstrate the mechanism of the observed capacity enhancement to be correlated with distributed storage at local nitrogen sites in a staged KC8 compound. This study demonstrates a pathway to overcome the limitations of graphitic carbons for anodes in potassium ion batteries by atomically precise engineering of nanomaterials.

AB - We investigated during the first lithiation/delithiation process the electrochemical reaction mechanisms at the surface of 30 nm n-doped amorphous silicon (a-Si) thin film used as a negative model electrode for Li-ion batteries. Usage of thin film allowed us to accurately discern the different reaction mechanisms occurring at the surface by avoiding interference from carbon and binder components. The potential dependency of the evolution of the solid electrolyte interphase (SEI) and the reactions on the a-Si and on the copper current collector were elucidated by coupling galvanostatic cycling with postmortem X-ray photoemission spectroscopy and scanning electron microscopy analyses. Our approach revealed the clear reversibility of lithiation/delithiation in the a-Si and native SiO2 layers; such a reaction for SiO2 has not been previously detected and was considered to be an irreversible process. Quantitative and qualitative analyses of the potential-dependent surface evolution revealed the decomposition products of both the salt (LiPF6) and solvent (dimethyl carbonate/ethylene carbonate), giving insight into the complex SEI formation mechanism on the a-Si film but also underlining the strong influence of "inert" materials such as the role of the current collector in the irreversible charge loss. A model mechanism describing the evolutionary complexity of the a-Si surface during the first galvanostatic cycle is proposed and discussed.

AB - Thiols and phosphines are the most widely used organic ligands to attain atomically precise metal nanoclusters (NCs). Here, we used simple hydrides (e.g., H-) as ligands along with phos-phines, such as triphenylphosphine (TPP), 1,2 bis(diphenylphosphino)ethane [DPPE], and tris(4-fluorophenyl)phosphine [TFPP] to design and synthesize a new class of hydride-rich silver NCs. This class includes [Ag18H16(TPP)10]2+, [Ag25H22(DPPE)8]3+, and [Ag26H22(TFPP)13]2+. Our work reveals a new family of atomi-cally precise NCs protected by H- ligands and labile phos phines, with potentially more accessible active metal sites for functionalization and provides a new set of stable NC sizes with simpler ligand-metal bonding for researchers to explore both experimentally and computationally. PMID- 27718550 TI - L30A Mutation of Phospholemman Mimics Effects of Cardiac Glycosides in Isolated Cardiomyocytes. AB - To determine if mutations introduced into phospholemman (PLM) could increase the level of PLM-Na,K-ATPase (NKA) binding, we performed scanning mutagenesis of the transmembrane domain of PLM and measured Forster resonance energy transfer (FRET) between each mutant and NKA. We observed an increased level of binding to NKA for several PLM mutants compared to that of the wild type (WT), including L27A, L30A, and I32A. In isolated cardiomyocytes, overexpression of WT PLM increased the amplitude of the Ca2+ transient compared to the GFP control. The Ca2+ transient amplitude was further increased by L30A PLM overexpression. The L30A mutation also delayed Ca2+ extrusion and increased the duration of cardiomyocyte contraction. This mimics aspects of the effect of cardiac glycosides, which are known to increase contractility through inhibition of NKA. No significant differences between WT and L30A PLM-expressing myocytes were observed after treatment with isoproterenol, suggesting that the superinhibitory effects of L30A are reversible with beta-adrenergic stimulation. We also observed a decrease in the extent of PLM tetramerization with L30A compared to WT using FRET, suggesting that L30 is an important residue for mediating PLM-PLM binding. Molecular dynamics simulations revealed that the potential energy of the L30A tetramer is greater than that of the WT, and that the transmembrane alpha helix is distorted by the mutation. The results identify PLM residue L30 as an important determinant of PLM tetramerization and of functional inhibition of NKA by PLM.

AB - We developed an in vitro DNA detection system using a pair of dCas9 proteins linked to split halves of luciferase. Luminescence was induced upon colocalization of the reporter pair to a ~44 bp target sequence defined by sgRNAs. We used the system to detect Mycobacterium tuberculosis DNA with high specificity and sensitivity. The reprogrammability of dCas9 was further leveraged in an array design that accesses sequence information across the entire genome. PMID- 27718554 TI - Reliable Memristive-Switching Memory Devices Enabled by Densely-Packed Silver Nanocone Arrays as Electric-Field Concentrators. AB - Memristor devices based on electrochemical metallization operate through electrochemical formation/dissolution of nanoscale metallic filaments, and they are considered a promising future nonvolatile memory because of their outstanding characteristics over conventional charge-based memories. However, nanoscale conductive paths or filaments precipitated from the redox process of metallic elements are randomly formed inside oxides resulting in unexpected and stochastic memristive switching parameters including the operating voltage and the resistance state. Here, we present the guided formation of conductive filaments in Ag nanocone/SiO2 nanomesh/Pt memristors fabricated by high-resolution nanotransfer printing. Consequently, the uniformity of the memristive switching behavior is significantly improved by the existence of electric field concentrator arrays consisting of Ag nanocones embedded in SiO2 nanomesh structures. This selective and controlled filament growth was experimentally supported by analyzing simultaneously the surface morphology and current-mapping results using conductive atomic-force microscopy. Moreover, stable multi-level switching operations with four discrete conduction states were achieved by the nanopatterned memristor device demonstrating its potential in high-density nanoscale memory devices.

AB - This article reports an effective method to regulate hydrophobic drug release rate from partially silica-coated bicellar nanodisc generated from proamphiphilic organoalkoxysilane and dihexanoylphosphatidylcholine by introducing different molar percentages of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-PEG2000 (DSPE-PEG2000) into planar bilayers of hybrid bicelles. It was found that the drug release rate increased with increasing the molar percentages of DSPE PEG2000, and 57.38%, 69.21%, 78.69%, 81.64%, and 82.23% of hydrophobic doxorubicin was released within 120 h from the nanodics incorporating with 0%, 2.5%, 5%, 10%, and 20% DSPE-PEG2000, respectively. Compared with the non PEGylated nanodisc and free doxorubicin, the PEGylated nanodiscs showed good biocompatibility, high cellular uptake, and adhesion, as well as high local drug accumulation. In addition, both in vitro and in vivo results demonstrated significantly improved antitumor efficacy of the PEGylated nanodisc than its control groups. Thus, the PEGylated nanodisc with partial silica coating offers a facile and efficient strategy of drug delivery for chemotherapy with improved patient acceptance and compliance.

AB - We report an in situ high-pressure NMR capability that permits natural abundance 17O and 25Mg NMR characterization of dissolved species in aqueous solution and in the presence of supercritical CO2 fluid (scCO2). The dissolution of Mg(OH)2 (brucite) in a multiphase water/scCO2 fluid at 90 atm pressure and 50 degrees C was studied in situ, with relevance to geological carbon sequestration. 17O NMR spectra allowed identification and distinction of various fluid species including dissolved CO2 in the H2O-rich phase, scCO2, aqueous H2O, and HCO3-. The widely separated spectral peaks for various species can all be observed both dynamically and quantitatively at concentrations as low as 20 mM. Measurement of the concentrations of these individual species also allows an in situ estimate of the hydrogen ion concentration, or pCH+ values, of the reacting solutions. The concentration of Mg2+ can be observed by natural abundance 25Mg NMR at a concentration as low as 10 mM. Quantum chemistry calculations of the NMR chemical shifts on cluster models aided in the interpretation of the experimental results. Evidence for the formation of polymeric Mg2+ clusters at high concentrations in the H2O-rich phase, a possible critical step needed for magnesium carbonate formation, was found.

AB - Monolayer transition-metal dichalcogenides (1L-TMDs) are atomically thin direct band gap semiconductors, from which the emission of light is determined by optical transitions of exciton complexes such as neutral excitons and trions. While the quantum yields of 1L-TMDs are quite low, the ability to control the populations of exciton complexes in 1L-TMDs through various doping processes is an interesting advantage, and provides ample possibilities for engineering the optical properties of these semiconductor monolayers. Here we demonstrate a simple method of controlling the populations of excitons and trions to enhance the light emission of 1L-TMDs by having them form heterostructures with ZnO thin films (TFs). 1Ls of MoS2 or MoSe2 showed up to 17-fold increases in photoluminescence (PL) when they were placed on ~50 nm thick ZnO TFs. This enhancement of the PL was due to charge exchanges occurring through the 1L TMD/ZnO interface. The PL enhancements and changes in the PL spectra of the 1L TMDs were greater when the 1L-TMD/ZnO heterostructures were subjected to 355 nm wavelength laser excitation than when they were excited with a 514 nm wavelength laser, which we attributed to the onset of energy transfer by photoexcited excitons and/or the additional p-doping by photoexcited holes in ZnO. The p doping phenomenon and the enhanced light emission of 1L-TMD/ZnO heterostructures were unambiguously visualized in spatially resolved PL and Raman spectral maps. Our approach using the 1L-TMD/ZnO TF heterostructure suggests that a rich variety of options for engineering the optical properties of 1L-TMDs may be made available by carrying out simple and intuitive manipulations of exciton complexes, and these endeavors may yield practical applications for 1L-TMDs in nanophotonic devices.

AB - As one of the most popular carbon-based nanomaterials, graphene oxide (GO) has the potential to be released in aquatic environment and interact with some coexistent organic pollutants, such as perfluorooctanesulfonate (PFOS), which is an emerging persistent organic pollutant. In this study, the adsorption of PFOS on GO in the presence of fulvic acid (FA), the impacts of GO and FA on PFOS toxicokinetics in carp (Cyprinus carpio), and in vitro digestion behaviors were examined. The results indicated that PFOS could be strongly adsorbed on GO with a Freundlich affinity coefficient KF of 580 +/- 205 (mg/g)/(mg/L)n, while the adsorption was suppressed by FA due to competitive adsorption. GO significantly enhanced the bioaccumulation of PFOS in blood, kidney, liver, gill, intestine, and muscle of carp, and the corresponding bioaccumulation factor (BAF) was in the range of 2026-53513 L/kg. The enhancement was greatest for liver and intestine, which was 10.3 and 9.33 times of that without GO, respectively. In vivo toxicokinetic and in vitro digestion-absorption experiments indicated that GO could carry PFOS to penetrate the intestine cells. There herein, PFOS absorption, especially via intestine, and the uptake rate coefficient (ku) were greatly enhanced, leading to distinctly promoted bioaccumulation of PFOS in fish. However, FA could facilitate the flocculation of GO in the intestine and also accelerate excretion of GO-PFOS complex. Thus, in the presence of FA, PFOS absorption was reduced and the promotion effect of GO on PFOS accumulation was remitted.

AB - Given that resistance to all drugs in clinical use has arisen, discovery of new antimalarial drug targets is eagerly anticipated. The Plasmodium mitochondrion has been considered a promising drug target largely based on its significant divergence from the host organelle as well as its involvement in ATP production and pyrimidine biosynthesis. However, the functions of Plasmodium mitochondrial protein complexes and associated metabolic pathways are not fully characterized. Here, we report the development of novel and robust bioenergetic assay protocols for Plasmodium falciparum asexual parasites utilizing a Seahorse Bioscience XFe24 Extracellular Flux Analyzer. These protocols allowed us to simultaneously assess the direct effects of metabolites and inhibitors on mitochondrial respiration and glycolytic activity in real-time with the readout of oxygen consumption rate and extracellular acidification rate. Using saponin-freed parasites at the schizont stage, we found that succinate, malate, glycerol-3-phosphate, and glutamate, but not pyruvate, were able to increase the oxygen consumption rate and that glycerol 3-phosphate dehydrogenase had the largest potential as an electron donor among tested mitochondrial dehydrogenases. Furthermore, we revealed the presence of a glucose-regulated metabolic shift between oxidative phosphorylation and glycolysis. We measured proton leak and reserve capacity and found bioenergetic evidence for oxidative phosphorylation in erythrocytic stage parasites but at a level much lower than that observed in mammalian cells. Lastly, we developed an assay platform for target identification and mode of action studies of mitochondria-targeting antimalarials. This study provides new insights into the bioenergetics and metabolomics of the Plasmodium mitochondria.

AB - A highly enantioselective allylic C-H alkylation reaction of allylarenes with pyrazol-5-ones has been established by the cooperative catalysis of a chiral palladium complex and chiral Bronsted acid to afford a wide spectrum of functionalized chiral N-heterocycles with an all-carbon quaternary stereogenic center in high yields and with high levels of enantioselectivity (up to 96% ee), wherein the chiral ligand and phosphoric acid showed synergistic effect on the control of stereoselectivity. In addition, a palladium-catalyzed asymmetric allylic C-H alkylation of 1,4-pentadienes with pyrazol-5-ones has been realized to furnish highly functionalized pyrazol-5-ones in high enantioselectivities. In this case, the chiral ligand controls the stereoselectivity while the achiral Bronsted acid, 2-fluorobenzoic acid, turns out to be a better cocatalyst than the chiral phosphoric acid. The installation of electron-deficient substituents at 3,3'-positions of binaphthyl backbone of chiral phosphoramidites is actually beneficial to the allylic C-H oxidation due to their survival in the presence of quinone derivative oxidants. These allylic C-H alkylation reactions undergo smoothly under mild conditions and tolerate a wide range of substrates. The resultant highly functionalized chiral pyrazol-5-ones have been applied to the preparation of more structurally diverse heterocycles by classical transformations. PMID- 27718561 TI - The Relevance of Oxygen for the Formation of Strecker Aldehydes during Beer Production and Storage. AB - Off-flavor in beer is often associated with the appearance of staling aldehydes. In this study, the factors amino acid concentration, carbohydrate concentration, Fe2+ concentration, and oxygen concentration were investigated in terms of their effect on the formation of carbonyl compounds during storage using response surface methodology. From all factors tested, only amino acid concentration and oxygen concentration promoted Strecker aldehyde formation during storage while all other carbonyls measured were unaffected. A mixture of glucose/xylose, representing carbohydrate sources, as well as Fe2+ concentration were insignificant factors; though, carbohydrate additions exhibited a significant role for the formation of 2-furfural. De novo formation of phenylacetaldehyde from phenylalanine during beer storage was observed using labeling experiments and a linear relationship between Strecker aldehydes formed and total packaged oxygen was identified. Capping beers with oxygen barrier crown corks and addition of 10 mg/L EDTA to beers effectively diminished Strecker aldehyde formation. Oxygen was additionally shown to significantly promote Strecker aldehyde formation during sweet wort production. A pathway for the reactive oxygen species induced degradation of amino acids yielding Strecker aldehydes was proposed and was further scrutinized in buffered model solutions. The insignificant role of Fe2+ in the response surface experiments is discussed.

AB - An inverse CeO2/Cu2O/Cu(111) catalyst is able to activate methane at room temperature producing C, CHx fragments and COx species on the oxide surface. The addition of water to the system leads to a drastic change in the selectivity of methane activation yielding only adsorbed CHx fragments. At a temperature of 450 K, in the presence of water, a CH4 ? CH3OH catalytic transformation occurs with a high selectivity. OH groups formed by the dissociation of water saturate the catalyst surface, removing sites that could decompose CHx fragments, and generating centers on which methane can directly interact to yield methanol.

This study examined the effects of nuciferine on fructose-induced renal injury and explored its possible mechanism. Rats consumed drinking water or 10% fructose for 12 wk. Fructose-fed rats were orally treated with water, or 7, 14 or 28 mg/kg nuciferine for the last 6 wk. HK-2 cells were exposed to 5 mM fructose alone or in combination with nuciferine (2.5-40 MUM) for 24 h. Nuciferine significantly attenuated fructose induced hyperuricemia, dyslipidemia and systemic inflammation in rats. More importantly, it alleviated renal pathological injury with proteinuria at 20 and 40 mg/kg (2.58 +/- 0.97 and 2.48 +/- 1.04 mg/mg.creatinine, P < 0.05) compared with fructose-vehicle group (4.10 +/- 1.18 mg/mg.creatinine). Furthermore, nuciferine reduced TLR4, MyD88, PI3K, ILK, p-AKT, p-P65 and NLRP3 inflammasome protein levels (P < 0.05 for all) in renal cortex of fructose-fed rats (14 and 28 mg/kg), and fructose-exposed HK-2 cells (5-40 MUM), being consistent with its reduction of inflammatory cytokines IL-1beta, IL-6, TNF-alpha, and MCP-1 (P < 0.05 for all) in vivo and in vitro. These findings suggested that nuciferine alleviated fructose-induced inflammation by inhibiting TLR4/PI3K/NF-kappaB signaling and NLRP3 inflammasome activation in rat renal cortex and HK-2 cells, which may contribute to the improvement of renal injury.

AB - A general and transition-metal-free access to the fused polycyclic pyrazoles via an intramolecular 1,3-dipolar cycloaddition reaction of alkyne-tethered tosylhydrazones has been reported. The pure solid products could be obtained without column chromatography in high to excellent yields, and the obtained products are useful bioactive molecules or could be used as the key intermediate for synthesis of these compounds in one or two steps. Additionally, a [3+2] cycloaddition followed by a direct H-shift aromatization reaction mechanism was proposed, which is different from the previously reported aryl or alkyl sequential [1,5]-sigmatropic rearrangement pathway.

AB - We report a combined experimental and modeling study of microwave-activated dilute CH4/N2/H2 plasmas, as used for chemical vapor deposition (CVD) of diamond, under very similar conditions to previous studies of CH4/H2, CH4/H2/Ar, and N2/H2 gas mixtures. Using cavity ring-down spectroscopy, absolute column densities of CH(X, v = 0), CN(X, v = 0), and NH(X, v = 0) radicals in the hot plasma have been determined as functions of height, z, source gas mixing ratio, total gas pressure, p, and input power, P. Optical emission spectroscopy has been used to investigate, with respect to the same variables, the relative number densities of electronically excited species, namely, H atoms, CH, C2, CN, and NH radicals and triplet N2 molecules. The measurements have been reproduced and rationalized from first-principles by 2-D (r, z) coupled kinetic and transport modeling, and comparison between experiment and simulation has afforded a detailed understanding of C/N/H plasma-chemical reactivity and variations with process conditions and with location within the reactor. The experimentally validated simulations have been extended to much lower N2 input fractions and higher microwave powers than were probed experimentally, providing predictions for the gas-phase chemistry adjacent to the diamond surface and its variation across a wide range of conditions employed in practical diamond-growing CVD processes. The strongly bound N2 molecule is very resistant to dissociation at the input MW powers and pressures prevailing in typical diamond CVD reactors, but its chemical reactivity is boosted through energy pooling in its lowest-lying (metastable) triplet state and subsequent reactions with H atoms. For a CH4 input mole fraction of 4%, with N2 present at 1-6000 ppm, at pressure p = 150 Torr, and with applied microwave power P = 1.5 kW, the near-substrate gas-phase N atom concentration, [N]ns, scales linearly with the N2 input mole fraction and exceeds the concentrations [NH]ns, [NH2]ns, and [CN]ns of other reactive nitrogen containing species by up to an order of magnitude. The ratio [N]ns/[CH3]ns scales proportionally with (but is 102-103 times smaller than) the ratio of the N2 to CH4 input mole fractions for the given values of p and P, but [N]ns/[CN]ns decreases (and thus the potential importance of CN in contributing to N-doped diamond growth increases) as p and P increase. Possible insights regarding the well-documented effects of trace N2 additions on the growth rates and morphologies of diamond films formed by CVD using MW-activated CH4/H2 gas mixtures are briefly considered.

Grazing-incidence X-ray diffraction depth profiling confirms the formation of a perovskite film with a PbI2-rich region close to the electron transport layer (ETL) due to the strong interaction of HMPA with PbI2, which successfully retarded the dissolution of the PbI2 phase when depositing the perovskite layer on top. These results are further confirmed by energy-dispersive X-ray spectroscopy performed in a scanning transmission electron microscope, which reveals that the I/Pb ratio in samples treated with the complex is indeed reduced in the vicinity of the ETL contact when compared to samples without the treatment. The engineered interface leads to an average power conversion efficiency of 19.2% (reverse scan, standard deviation SD < 0.2) over 30 cells (best cell at 19.5% with high FF of 0.80).

AB - The motion of self-propelled tubular micro- and nanojets has so far been achieved by bubble propulsion, e.g., O2 bubbles formed by catalytic decomposition of H2O2, which renders future biomedical applications inviable. An alternative self propulsion mechanism for tubular engines on the nanometer scale is still missing. Here, we report the fabrication and characterization of bubble-free propelled tubular nanojets (as small as 220 nm diameter), powered by an enzyme-triggered biocatalytic reaction using urea as fuel. We studied the translational and rotational dynamics of the nanojets as functions of the length and location of the enzymes. Introducing tracer nanoparticles into the system, we demonstrated the presence of an internal flow that extends into the external fluid via the cavity opening, leading to the self-propulsion. One-dimensional nanosize, longitudinal self-propulsion, and biocompatibility make the tubular nanojets promising for future biomedical applications.

AB - Rhenium diboride (ReB2), containing corrugated layers of covalently bonded boron, is a superhard metallic compound with a microhardness reaching as high as 40.5 GPa (under an applied load of 0.49 N). Tungsten diboride (WB2), which takes a structural hybrid between that of ReB2 and AlB2, where half of the boron layers are planar (as in AlB2) and half are corrugated (as in ReB2), has been shown not to be superhard. Here, we demonstrate that the ReB2-type structure can be maintained for solid solutions of tungsten in ReB2 with tungsten content up to a surprisingly large limit of nearly 50 atom %. The lattice parameters for the solid solutions linearly increase along both the a- and c-axes with increasing tungsten content, as evaluated by powder X-ray and neutron diffraction. From micro- and nanoindentation hardness testing, all of the compositions within the range of 0-48 atom % W are superhard, and the bulk modulus of the 48 atom % solid solution is nearly identical to that of pure ReB2. These results further indicate that ReB2-structured compounds are superhard, as has been predicted from first principles calculations, and may warrant further studies into additional solid solutions or ternary compounds taking this structure type.

AB - A recombinant anti-sarafloxacin ScFv antibody was produced by direct transformation of its gene into Rosetta-gami(DE3) for expression, and then its recognition mechanisms for 12 fluoroquinolones were studied by using molecular docking method. Based on the results of virtual mutation, the ScFv antibody was evolved by directional mutagenesis of contact amino acid residue Tyr99 to His. The ScFv mutant showed highly increased affinity for the 12 drugs with up to 7 folds improved sensitivity. Finally, the mutant was used to develop an indirect competitive enzyme linked immunosorbent assay for determination of the 12 drugs in milk. The limits of detection were in the range of 0.3-8.0 ng/mL, the crossreactivities were in the range of 5%-106%, and the recoveries from the standards fortified blank milk were in the range of 62.0%-89.3%. This is the first study reporting the evolution of a ScFv antibody by using directional mutagenesis strategy based on virtual mutation.

AB - Alkyl oxalates, prepared from their corresponding alcohols, are engaged for the first time as carbon radical fragments in metallaphotoredox catalysis. In this report, we demonstrate that alcohols, native organic functional groups, can be readily activated with simple oxalyl chloride to become radical precursors in a net redox-neutral Csp3-Csp2 cross-coupling with a broad range of aryl halides. This alcohol-activation coupling is successfully applied to the functionalization of a naturally occurring steroid and the expedient synthesis of a medicinally relevant drug lead. PMID- 27718571 TI - Assessment of DFT Functionals for QTAIM Topological Analysis of Halogen Bonds with Benzene. AB - Halogen bonding, a noncovalent interaction between a halogen atom and a nucleophilic site, is receiving a growing attention in the chemical community stimulating a large number of theoretical investigations. The density functional theory (DFT) approach revealed to be one of the most suitable methods owing to its accuracy and low computational cost. We report here a detailed analysis of the performance of an extensive set of DFT functionals in reproducing accurate binding energies and topological properties for the halogen-bonding interaction of either NCX or PhX molecules (X = F, Cl, Br, I) with the aromatic system of benzene in the T-shaped configuration. It was found that the better performance for both sets of properties is provided by a small subset of functionals able to take into account, implicitly or explicitly (by inclusion of an additive pairwise potential), the dispersion contribution, that is, omegaB97X, M06-2X, M11, mPW2PLYP-D, and B2PLYP-D3. PMID- 27718572 TI - Amino Acid Specific Effects on RNA Tertiary Interactions: Single-Molecule Kinetic and Thermodynamic Studies. AB - In light of the current models for an early RNA-based universe, the potential influence of simple amino acids on tertiary folding of ribozymal RNA into biochemically competent structures is speculated to be of significant evolutionary importance. In the present work, the folding-unfolding kinetics of a ubiquitous tertiary interaction motif, the GAAA tetraloop-tetraloop receptor (TL TLR), is investigated by single-molecule fluorescence resonance energy transfer spectroscopy in the presence of natural amino acids both with (e.g., lysine, arginine) and without (e.g., glycine) protonated side chain residues. By way of control, we also investigate the effects of a special amino acid (e.g., proline) and amino acid mimetic (e.g., betaine) that contain secondary or quaternary amine groups rather than a primary amine group. This combination permits systematic study of amino acid induced (or amino acid like) RNA folding dynamics as a function of side chain complexity, pKa, charge state, and amine group content. Most importantly, each of the naturally occurring amino acids is found to destabilize the TL-TLR tertiary folding equilibrium, the kinetic origin of which is dominated by a decrease in the folding rate constant (kdock), also affected by a strongly amino acid selective increase in the unfolding rate constant (kundock). To further elucidate the underlying thermodynamics, single-molecule equilibrium constants (Keq) for TL-TLR folding have been probed as a function of temperature, which reveal an amino acid dependent decrease in both overall exothermicity (DeltaDeltaH degrees > 0) and entropic cost (-TDeltaDeltaS degrees < 0) for the overall folding process. Temperature-dependent studies on the folding/unfolding kinetic rate constants reveal analogous amino acid specific changes in both enthalpy (DeltaDeltaH?) and entropy (DeltaDeltaS?) for accessing the transition state barrier. The maximum destabilization of the TL-TLR tertiary interaction is observed for arginine, which is consistent with early studies of arginine and guanidine ion-inhibited self-splicing kinetics for the full Tetrahymena ribozyme [ Yarus , M. ; Christian , E.

AB - 1,4-Dioxenes present interesting potential as synthetic intermediates and as unusual motifs for incorporation into biologically active compounds. Here, an efficient synthesis of functionalized 1,4-dioxenes is achieved in two steps. Using keto-diazo compounds, a ruthenium catalyzed O-H insertion with beta halohydrins followed by treatment with base results in cyclization with excellent selectivity, through O-alkylation of the keto-enolate. A variety of halohydrins and anion-stabilizing groups in the diazo-component are tolerated, affording novel functionalized dioxenes. Enantioenriched beta-bromohydrins provide enantioenriched 1,4-dioxenes. PMID- 27718574 TI - Benzoxazinoids in Prostate Cancer Patients after a Rye-Intensive Diet: Methods and Initial Results. AB - Rye bread contains high amounts of benzoxazinoids, and in vitro studies have shown suppressive effects of selected benzoxazinoids on prostate cancer cells. Thus, research into benzoxazinoids as possible suppressors of prostate cancer is demanded. A pilot study was performed in which ten prostate cancer patients received a rye-enriched diet 1 week prior to prostatectomy. Plasma and urine samples were collected pre- and postintervention. Ten prostate biopsies were obtained from each patient and histologically evaluated. The biopsies exhibited concentrations above the detection limit of seven benzoxazinoids ranging from 0.15 to 10.59 ng/g tissue. An OPLS-DA analysis on histological and plasma concentrations of benzoxazinoids classified the subjects into two clusters. A tendency of higher benzoxazinoid concentrations toward the benign group encourages further investigations. Benzoxazinoids were quantified by an optimized LC-MS/MS method, and matrix effects were evaluated. At low concentrations in biopsy and plasma matrices the matrix effect was concentration-dependent and nonlinear. For the urine samples the general matrix effects were small but patient-dependent. PMID- 27718573 TI - Antitumor Activity of Lankacidin Group Antibiotics Is Due to Microtubule Stabilization via a Paclitaxel-like Mechanism. AB - Lankacidin group antibiotics show strong antimicrobial activity against various Gram-positive bacteria. In addition, they were shown to have considerable antitumor activity against certain cell line models. For decades, the antitumor activity of lankacidin was associated with the mechanism of its antimicrobial action, which is interference with peptide bond formation during protein synthesis. This, however, was never confirmed experimentally. Due to significant similarity to paclitaxel-like hits in a previous computational virtual screening study, we suggested that the cytotoxic effect of lankacidin is due to a paclitaxel-like action. In this study, we tested this hypothesis computationally and experimentally and confirmed that lankacidin is a microtubule stabilizer that enhances tubulin assembly and displaces taxoids from their binding site. This study serves as a starting point for optimization of lankacidin derivatives for better antitumor activities. It also highlights the power of computational predictions and their aid in guiding experiments and formulating rigorous hypotheses. PMID- 27718576 TI - Revisiting the Dielectric Constant Effect on the Nucleophile and Leaving Group of Prototypical Backside Sn2 Reactions: a Reaction Force and Atomic Contribution Analysis. AB - The solvent effect on the nucleophile and leaving group atoms of the prototypical F- + CH3Cl -> CH3F + Cl- backside bimolecular nucleophilic substitution reaction (SN2) is analyzed employing the reaction force and the atomic contributions methods on the intrinsic reaction coordinate (IRC). Solvent effects were accounted for using the polarizable continuum solvent model. Calculations were performed employing eleven dielectric constants, epsilon, ranging from 1.0 to 78.5, to cover a wide spectrum of solvents. The reaction force data reveals that the solvent mainly influences the region of the IRC preceding the energy barrier, where the structural rearrangement to reach the transition state occurs. A detailed analysis of the atomic role in the reaction as a function of epsilon reveals that the nucleophile and the carbon atom are the ones that contribute the most to the energy barrier. In addition, we investigated the effect of the choice of nucleophile and leaving group on the DeltaE0 and DeltaE? of Y- + CH3X -> YCH3 + X- (X,Y= F, Cl, Br, I) in aqueous solution. Our analysis allowed us to find relationships between the atomic contributions to the activation energy and leaving group ability and nucleophilicity. PMID- 27718578 TI - Synthesis, Structure, and Reactivity of a Cylinder-Shaped Cyclo[12]orthophenylene[6]ethynylene: Toward the Synthesis of Zigzag Carbon Nanobelts. AB - Benzannulated cyclacenes (BCs) have been proposed as stable zigzag carbon nanobelts. Density functional theory (DFT) calculations revealed a closed-shell ground state for [12]BC, whereas an open-shell ground state was suggested for [12]cyclacene. The calculated strain energy and frontier molecular orbital energies of [12]BC also implied high stability. An unstrained macrocycle 1, consisting of orthophenylene and ethynylene moieties, was designed as a potential precursor for [12]BC and synthesized by sequential Suzuki-Miyaura cross-coupling of diphenylacetylene derivatives. While the conversion of 1 into [12]BC is still under investigation, an unexpected rearrangement of the triene moieties in 1, affording a tribenzo[f,k,m]tetraphene structure, was discovered during the screening of reaction conditions. An attempt was made to rationalize this result by proposing a plausible reaction mechanism that proceeds via intermediates containing cyclobutadiene or Dewar benzene moieties. The proposed mechanism is partially supported by DFT calculations.

AB - The ingestion of foods and food-derived substances that may mediate the immune system is widely studied. Evidence suggests cereal arabinoxylans (AXs) have immunomodulatory activities that may impart health benefits in terms of immune enhancement. This study extracted AXs from corn bran using alkali and developed a modification process using three endoxylanases to obtain fractions of lower molecular weight ranges. In vitro studies showed extracted and modified AXs significantly (P < 0.05) elevated nitric oxide (NO) synthesis by the human U937 monocytic cell line (ranging from 53.7 +/- 1.1 to 62.9 +/- 1.2 MUM per million viable cells) at all concentrations tested (5-1000 MUg/mL), indicative of immune enhancement compared to an untreated control (43.7 +/- 1.9 MUM per million viable cells). The study suggested the dose range and Mw distribution of AXs are key determinants of immune-modulatory activity. AXs in the low Mw range (0.1-10 KDa) were the most effective at inducing NO secretion by U937 macrophages at low AX concentration ranges (5-50 MUg/mL), with NO production peaking at 62.9 +/- 1.2 MUM per million viable cells with 5 MUg/mL of AX (P = 0.0009). In contrast, AXs in the high Mw range (100-794 kDa) were most effective at inducing NO at high AX concentration ranges (500-1000 MUg/mL) with NO production reaching a maximum of 62.7 +/- 1.3 MUM per million viable cells at 1000 MUg/mL of AX (P = 0.0011). The findings suggest that dietary AXs from corn bran may heighten innate immune responses in the absence of infection or disease. PMID- 27718579 TI - Superior Catalytic Performance of Gold Nanoparticles Within Small Cross-Linked Lysozyme Crystals. AB - Bionanomaterials synthesized by bio-inspired templating methods have emerged as a novel class of composite materials with varied applications in catalysis, detection, drug delivery, and biomedicine. In this study, two kinds of cross linked lysozyme crystals (CLLCs) of different sizes were applied for the in situ growth of Au nanoparticles (AuNPs). The resulting composite materials were characterized by light microscopy, scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, and X-ray photoelectron spectroscopy. The catalytic properties of the prepared materials were examined in the catalytic reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP). It was found that the size of the AuNPs increased with an increase in Au loading for both small and large crystals. In addition, small crystals favored homogeneous adsorption and distribution of the metal precursors. And the size of the AuNPs within small crystals could be maintained below 2.5 nm by managing the HAuCl4/lysozyme molar ratio. Furthermore, the lysozyme functional groups blocked the AuNP activity sites, therefore reducing their catalytic activity. This effect was more pronounced for small AuNPs. Moreover, the mass transfer of reactants (4 NP) from solution to AuNPs within the crystals restricted their catalytic reduction, leading to superior catalytic performance of the AuNPs within small cross-linked lysozyme crystals (Au@S-CLLCs) compared to those within large cross linked lysozyme crystals (Au@L-CLLCs) at similar Au loadings. Finally, an increase in Au loading clogged the crystal channels with increased quantities of larger aggregated AuNPs, thus impeding the catalytic performance of Au@S-CLLCs. PMID- 27718580 TI - Comparative proteomics implicates a role for multiple secretion systems in electrode-respiring Geobacter sulfurreducens biofilms. AB - Geobacter sulfurreducens is a dissimilatory metal-reducing bacterium capable of forming thick electron-conducting biofilms on solid electrodes. Here, we employ for the first time comparative proteomics to identify key physiological changes involved in G. sulfurreducens adaptation from fumarate-respiring planktonic cells to electron-conducting biofilms. Increased levels of proteins involved in outer membrane biogenesis, cell motility and secretion are expressed in biofilms. Of particular importance to the electron-conducting biofilms are proteins associated with secretion systems of Type I, II, V and Type IV pili. Furthermore, enzymes involved in lipopolysaccharide and peptidoglycan biosynthesis show increased levels of expression in electron-conducting biofilms compared to planktonic cells. These observations point to similarities in long-range electron transfer mechanisms between G. sulfurreducens and Shewanella oneidensis, while highlighting the wider significance of secretion systems beyond that of Type IV pili identified to date in the adaptation of G. sulfurreducens to electrode respiration.

PMID- 27718582 TI - All-Printed Differential Temperature Sensor for the Compensation of Bending Effects. AB - Because printed resistance temperature detectors (RTDs) are affected by tension and compression of metallic patterns on flexible or curved surfaces, a significant temperature-sensing error occurs in general. Hence, we propose a differential temperature sensor (DTS) to compensate the bending effect of the printed RTDs, which is composed of two serially connected similar meander patterns fabricated back-to-back on a polyimide polyethylene terephthalate substrate through a Dimatix DMP-3000 inkjet printer using silver nanoparticles. Under mechanical deformation, the resistance of the proposed DTS is not varied significantly under the same temperature environment because its patterns vary differentially as one side experiences tension while the opposite side experiences compression. A single meander pattern of the proposed DTS has a total length of 75 mm and device dimensions of 7 * 7 mm2. The total resistance variation is observed to be 15.5 Omega against the temperature variation from 0 to 100 degrees C, and the temperature coefficient of resistance is 1.076 * 10-3 degrees C-1. The proposed DTS exhibits no significant resistance change on bendability testing down to 2 mm diameter because of mechanical deformation. In addition, it is also used to detect the curvature of a body shape down to 2 mm diameter because its resistance changes by +/-8.22% using a single meander pattern of DTS. The proposed sensor can be applied on a curved or flexible surface to measure relatively accurate temperature when compared to a single meander pattern.

PMID- 27718586 TI - Enantioselective Protonation of Silyl Enol Ether Using Excited State Proton Transfer Dyes. AB - Enantiopure excited state proton transfer (ESPT) dyes were used for the asymmetric protonation of silyl enol ether. Under 365 nm irradiation, with 3,3' dibromo-VANOL as the ESPT dye, up to 49% enantioselectivity with a 68% yield of product was observed at room temperature. The reaction is effective with a range of silyl enol ethers and can also be achieved with visible light upon the addition of triplet sensitizer. The relatively low ee of the protonated product is due to the racemization/decomposition of the ESPT dye in the excited state as indicated by circular dichroism, HPLC, and UV-vis spectroscopy.

AB - The protein adsorption of two human plasma proteins-albumin (Alb) and fibronectin (Fn)-onto synthetic nanostructured bactericidal material-black silicon (bSi) surfaces (that contain an array of nanopillars) and silicon wafer (nonstructured) surfaces-was investigated. The adsorption behavior of Alb and Fn onto two types of substrata was studied using a combination of complementary analytical techniques. A two-step Alb adsorption mechanism onto the bSi surface has been proposed. At low bulk concentrations (below 40 MUg/mL), the Alb preferentially adsorbed at the base of the nanopillars. At higher bulk concentrations, the Alb adsorbed on the top of the nanopillars. In the case of Fn, the protein preferentially adsorbed on the top of the nanopillars, irrespective of its bulk concentration. PMID- 27718588 TI - Probing the Influence of Dielectric Environment on Excitons in Monolayer WSe2: Insight from High Magnetic Fields. AB - Excitons in atomically thin semiconductors necessarily lie close to a surface, and therefore their properties are expected to be strongly influenced by the surrounding dielectric environment. However, systematic studies exploring this role are challenging, in part because the most readily accessible exciton parameter-the exciton's optical transition energy-is largely unaffected by the surrounding medium. Here we show that the role of the dielectric environment is revealed through its systematic influence on the size of the exciton, which can be directly measured via the diamagnetic shift of the exciton transition in high magnetic fields. Using exfoliated WSe2 monolayers affixed to single-mode optical fibers, we tune the surrounding dielectric environment by encapsulating the flakes with different materials and perform polarized low-temperature magneto absorption studies to 65 T. The systematic increase of the exciton's size with dielectric screening, and concurrent reduction in binding energy (also inferred from these measurements), is quantitatively compared with leading theoretical models. These results demonstrate how exciton properties can be tuned in future 2D optoelectronic devices. PMID- 27718589 TI - Increased glucose utilization and cell growth of Corynebacterium glutamicum by modifying the glucose-specific phosphotransferase system (PTSGlc) genes. AB - The phosphoenolpyruvate:glucose phosphotransferase system (PTSGlc) is the major pathway of glucose uptake in Corynebacterium glutamicum. This study investigated glucose consumption rate, cell growth, and metabolite changes resulting from modification of PTSGlc. The classical l-lysine producer C. glutamicum XQ-8 exhibited low glucose consumption, cell growth, and l-lysine production rates, whereas these parameters were significantly increased during cultivating on glucose plus maltose, through inactivation of SugR, or by overexpression of PTSGlc genes. XQ-8sugR::cat/pDXW-8-ptsI exhibited the highest increase in glucose consumption, growth rate, and l-lysine production, followed by XQ-8sugR::cat/pDXW 8-ptsG. However, overexpression of ptsH had little effect on the above-mentioned factors. Although co-overexpression of ptsGHI led to the highest glucose consumption, growth rate, and final l-lysine production; the l-lysine production rate was lower than that of XQ-8sugR::cat/pDXW-8-ptsIH. In fed-batch fermentation, XQ-8sugR::cat/pDXW-8-ptsIH had a higher growth rate of 0.54 h-1 to a dry cell mass of 66 g.L-1 after 16 h, and had a higher l-lysine production rate of 159.2 g.L-1 after 36 h. These results indicate that modification of the sugar transport systems improves amino acid production, especially for mutants obtained by repeated physical and (or) chemical mutagenesis. However, modification of these systems needs to be performed on a case-by-case basis. PMID- 27718590 TI - Experiences With and Perceptions of Workplace Bullying Among Athletic Trainers in the Secondary School Setting. AB - CONTEXT: Workplace bullying (WPB) has recently received much attention in society. Research on WPB in athletic training practice settings is limited. OBJECTIVE: To determine the prevalence of WPB in the secondary school setting and explore the factors related to it. DESIGN: Mixed-methods study. SETTING: Secondary school. PATIENTS OR OTHER PARTICIPANTS: A total of 567 athletic trainers (women = 322 [56.8%], men = 245 [43.2%]), aged 36.5 +/- 11.1 years with 11.9 +/- 9.5 years of experience took part in phase I. Ten participants (7 women and 3 men), aged 39.3 +/- 10.1 years with 14.3 +/- 8.3 years of experience, took part in phase II. DATA COLLECTION AND ANALYSIS: For the online survey, we used the previously validated and reliable (Cronbach alpha = .84) Athletic Training Workplace Environment Survey, which included the Negative Acts Questionnaire Revised. The prevalence of WPB was measured with descriptive statistics, and chi2 analyses were used to compare differences between groups (ie, females and males, perpetrators' titles). The interview data were examined using an inductive content analysis. RESULTS: Of the participants, 44 (7.8%) were empirically identified as targets of bullying, though a higher percentage (12.4%, n = 70) self-identified as bullying targets. Men and women did not differ with respect to having experienced WPB, but more perpetrators were male (71.6%, n = 48) than female (28.4%, n = 19; chi21 = 12.55, P = <.001). We also observed a difference in perpetrators' titles, with the vast majority of bullies being coaches or administrators (chi26 = 33.82, P = <.001). Lack of administrator support and discrimination were antecedents of bullying. Stress, depression, and sleep disturbances were reported consequences. Participants coped with bullying by avoidance and role refocusing. CONCLUSIONS: Bullying was experienced by a small percentage of athletic trainers in the secondary school setting, a contrast to the findings in the collegiate practice setting. PMID- 27718591 TI - Probiotic Lactobacillus casei expressing porcine antimicrobial peptide PR39 elevates antibacterial activity in the gastrointestinal tract. AB - PR39, a 4.7 kDa proline-rich antimicrobial peptide, acts as a cationic host defense peptide. In addition to killing bacteria, PR39 mediates inflammatory reactions, including cell proliferation, migration, wound healing, and angiogenesis. Here, we examined the antibacterial effects of this peptide. The synthetic gene fragment PR39 was inserted into the secretory expression vector plasmid pPG:612 of Lactobacillus casei, yielding the recombinant strain pPG:612 PR39/L. casei 393. In vitro antibacterial tests showed that expression of the PR39 peptide in recombinant L. casei resulted in antibacterial activity against Escherichia coli and Salmonella but had only minor antibacterial effects in Staphylococcus aureus. In addition, BALB/c mice fed the recombinant pPG:612 PR39/L. casei 393 grew better and had increased peripheral blood lymphocyte percentages, white blood cell numbers, and spleen indices than mice in the control group. Scanning electron microscopy showed that jejunum and duodenum villus height, crypt depth, and the ratio of villus height/crypt depth in the intestinal villi also increased. Moreover, mice fed the recombinant strain showed significantly lower mortality rates than the control group mice when challenged with the enterotoxigenic E. coli K88+. Thus, this recombinant expression system had the beneficial characteristics of both L. casei and PR39, supporting its potential as an animal feed additive. PMID- 27718593 TI - Responsible behaviour.

AB - OBJECTIVE: To prospectively assess the role of whole-lesion apparent diffusion coefficient (ADC) metrics in the characterization of breast tumours by comparing ADC value with ADC entropy. METHODS: 49 patients with 53 breast lesions underwent phased-array breast coil 1.5-T MRI. Two radiologists experienced in breast MRI, blinded to the final diagnosis, reviewed the ADC maps and placed a volume of interest on all slices including each lesion on the ADC map to obtain whole lesion mean ADC value and ADC entropy. The mean ADC value and ADC entropy in benign and malignant lesions were compared by the Mann-Whitney U-test. Receiver operating characteristic analysis was performed to assess the sensitivity and specificity of the two variables in the characterization of the breast lesions. RESULTS: The benign (n = 19) and malignant lesions (n = 34) had mean diameters of 20.8 mm (10.1-31.5 mm) and 26.4 mm (10.5-42.3 mm), respectively. The mean ADC value of the malignant lesions was significantly lower than that of the benign ones (0.87 * 10-3 vs 1.49 * 10-3 mm2 s-1; p < 0.0001). Malignant ADC entropy was higher than benign entropy, without reaching levels of statistical significance (5.4 vs 5.0; p = 0.064). At a mean ADC cut-off value of 1.16 * 10-3 mm2 s-1, the sensitivity and specificity for diagnosing malignancy became optimal (97.1% and 93.7, respectively) with an area under the curve (AUC) of 0.975. With regard to ADC entropy, the sensitivity and specificity at a cut-off of 5.18 were 67.6 and 68.7%, respectively, with an AUC of 0.664. CONCLUSION: Whole-lesion mean ADC could be a helpful index in the characterization of suspicious breast lesions, with higher sensitivity and specificity than ADC entropy. Advances in knowledge: Two separate parameters of the whole-lesion histogram were compared for their diagnostic accuracy in characterizing breast lesions. Mean ADC was found to be able to characterize breast lesions, whereas entropy proved to be unable to differentiate benign from malignant breast lesions. It is, however, likely that entropy may distinguish these two groups if a larger cohort were used, or the fact that this may be influenced by the molecular subtypes of breast cancers included.

PMID- 27718605 TI - Dentofacial traits in association with lower incisor alveolar cancellous bone thickness: A multiple regression analysis. AB - OBJECTIVE: To identify dentofacial anatomic traits associated with lower incisor cancellous bone thickness (LICBT) and then to assess their separate contributions and their combined contributions to the variation in LICBT. MATERIALS AND METHODS: A consecutive sample of cone beam computed tomography (CBCT) data taken in a university hospital within the same setting was retrospectively reviewed. Within the sample, CBCT data of 252 eligible subjects were reconstructed and measured for LICBT, facial traits, and mandibular symphyseal traits. A backward multiple linear regression was employed to explore the association between LICBT and seven representative dentofacial traits. RESULTS: Four dentofacial traits (vertical facial pattern, transverse jaw relationship, lower incisor cervical diameter, and mandibular symphyseal width) were identified as significantly associated with LICBT. The combination of these four factors could predict 64.3% of variations in LICBT (adjusted R2 = 0.643). Further comparison of LICBT among different transverse jaw relationships suggested that the LICBT of the normal (5.94 +/- 1.58 mm) group and the inferior convergent group (5.38 +/- 1.32 mm) were significantly larger than that of the crossbite group (4.34 +/- 1.27 mm) and the superior convergent group (4.53 +/- 1.67 mm). CONCLUSIONS: The bony support of lower incisors is significantly associated with several dentofacial traits. Reduced lower incisor bony support was statistically associated with increased vertical facial pattern, transverse jaw discrepancy, thinner mandibular symphyseal width, and smaller lower incisor cervical diameter.

AB - The present study investigated the comparative effects of piperine (PIP) - the active ingredient of black and long peppers - and simvastatin (SIM) on hepatic steatosis in hyperlipidemic rats. Male Wistar rats were fed a cholesterol mixture daily by intragastric gavage for 8 weeks. Piperine was given by oral gavage 8 h after cholesterol feeding. The animals were divided into 4 groups: control, high fat (HF), high fat plus 40 mg PIP/kg, and high fat plus 2 mg SIM/kg. At the end of the treatment, liver cholesterol, triglyceride, thiobaribituric reacting substances, superoxide dismutase (SOD), serum aminotransferase (AST), and alanine transferase (ALT) were measured. The result demonstrated that PIP and SIM significantly reduced the accumulation of cholesterol, triglyceride, and lipid peroxidation in the liver, while elevation of SOD was observed. The activities of AST and ALT significantly decreased in PIP when compared with the HF group. Our in vitro study of pancreatic lipase also showed the inhibitory effect of PIP higher than 30% at 5 mmol/L. These results demonstrate that PIP has beneficial effects in the treatment and (or) prevention of fat accumulation in the liver and that this mechanism is due to the inhibition of pancreatic lipase and the improvement of oxidative status.

PMID- 27718637 TI - New levothyroxine formulation meeting 95-105% specification over the whole shelf life: results from two pharmacokinetic trials. AB - OBJECTIVE: Small levothyroxine (L-T4) dose changes can lead to significant clinical effects. To ensure thyroid hormone levels are safely maintained, authorities are increasingly adopting stricter potency specifications for L-T4, the most stringent of these being 95-105% of the labeled dose over the whole shelf-life. Levothyroxine sodium (Euthyrox, Eutirox, Levothyrox ) has been reformulated, and two studies performed, to ensure bioequivalence to the currently marketed formulation and dosage form proportionality of the new formulation. METHODS: The bioequivalence study was an open-label, randomized, single-dose, two-period, two-sequence crossover comparing the highest dosage strengths of the currently marketed and the new L-T4 formulation at a total dose of 600 MUg. The dosage form proportionality study was an open-label, randomized, three-period, six-sequence crossover, comparing 50 MUg, 100 MUg, and 200 MUg L-T4 tablets, at a total dose of 600 MUg. Blood samples were taken at predefined time intervals. Primary outcomes were area under the curve (AUC) and maximum concentration (Cmax) of thyroxine (T4) in plasma. RESULTS: In the bioequivalence study, comparing the T4 profiles for the new and current formulation of L-T4, the geometric least square mean ratio of the baseline-adjusted AUC0-72,adj was 99.3% (90% confidence interval [CI]: 95.6-103.2) and the Cmax,adj was 101.7% (90% CI: 98.8-104.6). Bioequivalence was established if the 90% CI lay within the predefined 0.9-1.11 limits. In the dosage form proportionality study, pairwise comparisons ranged from 99.3% to 104.8%, and all 95% CIs were within the predefined CI range (0.8-1.25): the three dose strengths were dosage form proportional. CONCLUSIONS: The new formulation of L-T4 meets the most stringent potency specification guidelines, and has been demonstrated to be bioequivalent to the current formulation and to show dosage form proportionality. The new formulation will enable patients to receive a dose fine tuned to their medical needs, contributing to improved safety in the use of L-T4. PMID- 27718638 TI - SET protein overexpression contributes to paclitaxel resistance in MCF-7/S cells through PI3K/Akt pathway. AB - Patient SE translation (SET) is a carcinogen in facilitating cellular growth and proliferation, and promoting tumorigenesis and metastasis. The present study was to investigate the resistance mechanisms associated with SET in paclitaxel induced human breast cancer cells. The different expressions of SET, ATP-binding cassette (ABC) transporters and PI3K/Akt pathway between paclitaxel sensitive MCF 7/S and paclitaxel resistant MCF-7/PTX cells were identified using western blotting. We adopted plasmid transfection to upregulate SET in MCF-7/S cells and a novel SET antagonist COG112 to decrease SET in MCF-7/PTX cells. Subsequently, cell viability to paclitaxel was assessed by MTT assay and cell apoptosis was analyzed by flow cytometry. We found that levels of SET, ABC transporters and PI3K/Akt pathway were elevated in MCF-7/PTX. Upregulation of SET in MCF-7/S cells expressed resistant to paclitaxel and decreased cell apoptosis. Moreover, overexpression of SET promoted the mRNA and protein level of ABC transporters and PI3K/Akt signal pathway in MCF-7/S cells. Conversely, decreased level of SET by COG112 not only significantly sensitized MCF-7/PTX cells to paclitaxel, but also enhanced paclitaxel-induced cell apoptosis. Additionally, the levels of the ABC transporters and PI3K/Akt signal pathway were also reduced in the COG112-treated MCF-7/PTX cells. The above results demonstrated that SET was associated with paclitaxel resistance in MCF-7/PTX cells. PMID- 27718639 TI - Perspective: 4beta-hydroxycholesterol as an emerging endogenous biomarker of hepatic CYP3A. AB - A key goal in the clinical development of a new molecular entity is to quickly identify whether it has the potential for drug-drug interactions. In particular, confirmation of in vitro data in the early stage of clinical development would facilitate the decision making and inform future clinical pharmacology study designs. Plasma 4beta-hydroxycholesterol (4beta-HC) is considered as an emerging endogenous biomarker for cytochrome P450 3A (CYP3A), one of the major drug metabolizing enzymes. Although there are increasing reports of the use of 4beta HC in academic- and industry-sponsored clinical studies, a thorough review, summary and consideration of the advantages and challenges of using 4beta-HC to evaluate changes in CYP3A activity has not been attempted. Herein, we review the biology of 4beta-HC, its response to treatment with CYP3A inducers, inhibitors and mixed inducer/inhibitors in healthy volunteers and patients, the association of 4beta-HC with other probes of CYP3A activity (e.g. midazolam, urinary cortisol ratios), and present predictive pharmacokinetic models. We provide recommendations for studying hepatic CYP3A activity in clinical pharmacology studies utilizing 4beta-HC at different stages of drug development. PMID- 27718640 TI - Targeted upper-limb Wii-based Movement Therapy also improves lower-limb muscle activation and functional movement in chronic stroke. AB - PURPOSE: Post-stroke hemiparesis may manifest as asymmetric gait, poor balance, and inefficient movement patterns. We investigated improvements in lower-limb muscle activation and function during Wii-based Movement Therapy (WMT), a rehabilitation program specifically targeting upper-limb motor-function. METHODS: Electromyography (EMG) was recorded bilaterally from tibialis anterior (TA) in 20 stroke patients during a 14-day WMT program. EMG amplitude and burst duration were analyzed during stereotypical movement sequences of WMT activities. Functional movement ability was assessed pre- and post-therapy including 6-min walk test (6MWT), stair-climbing speed, and Wolf Motor Function Test timed-tasks. RESULTS: TA EMG burst duration during Wii-golf increased by 30% on the more affected side (p = 0.04) and decreased by 28% on the less-affected side. Patients who did not step during Wii-tennis had a 16% decrease in more-affected TA burst sum (p = 0.047) resulting in more symmetrical activation ratio at late-therapy, with the ratio changing from 3.24 +/- 2.25 to 0.99 +/- 0.11 (p = 0.047). Six minute walk and stair-climbing speed improved (p = 0.005 and 0.03, respectively), as did upper-limb movement (p <= 0.001). CONCLUSION: This study provides physiological evidence for lower-limb improvements with WMT. Different patterns of muscle activation changes were evident across the WMT activities. Despite the relatively good pre-therapy lower-limb function, muscle activation and symmetry improved significantly with upper-limb WMT. Implications for rehabilitation WMT is an upper-limb neurorehabilitation program that also improves lower-limb motor function. We report a shift towards more symmetrical muscle activation of tibialis anterior on the more- and less-affected sides that were reflected in increased distance walked during the 6MWT. The use of standing during therapy not only improves lower-limb function but also permits larger and more powerful upper limb movements. Targeted upper-limb rehabilitation can also significantly improve mobility and balance, whether dynamic or static, that should reduce the risk of falls post-stroke. PMID- 27718641 TI - Discovery and optimization of peptide macrocycles. AB - INTRODUCTION: Macrocyclic peptides are generally more resistant to proteolysis and often have higher potency than linear peptides and so they are excellent leads in drug design. Their study is significant because they offer potential as a new generation of drugs that are potent and specific, and thus might have fewer side effects than traditional small molecule drugs. Areas covered: This article covers macrocyclic drug leads based on nature-derived cyclic peptides as well as synthetic cyclic peptides and close derivatives. The natural peptides include cyclotides, sunflower-derived peptides, theta-defensins and orbitides. Technologies to make engineered cyclic peptides covered here include cyclization via amino acid linkers, CLIPS, templates, and stapled peptides. Expert opinion: Macrocyclic peptides are promising drug leads and several are in clinical trials. The authors believe they offer key advantages over traditional small molecule drugs, as well as some advantages over protein-based 'biologics' such as antibodies or growth factors. These include the ability to penetrate cells and attack intracellular targets such as protein-protein interactions as well as to hit extracellular targets. Some macrocyclic peptides such as cyclotides offer the potential for production in plants, thus reducing manufacture costs and potentially increasing opportunities for their distribution to developing countries at low cost. PMID- 27718642 TI - Assessing subacute mild traumatic brain injury with a portable virtual reality balance device. AB - PURPOSE: Balance impairment is a common sensorimotor symptom in mild traumatic brain injury (mTBI). We designed an affordable, portable virtual reality (VR) based balance screening device (Virtual Environment TBI Screen [VETS]), which will be validated relative to the Neurocom Sensory Organization Test (SOT) to determine if it can replace commonly used postural assessments. METHODS: This preliminary study examines healthy adults (n = 56) and adults with mTBI (n = 11). Participants performed six upright postural tasks on the VETS and the SOT. Analysis of variance was used to determine between-group differences. Pearson's correlations were used to establish construct validity. Known-groups approach was used to establish classification accuracy. RESULTS: The mTBI cohort performed significantly worse than the healthy cohort on the new device (p = 0.001). The new device has 91.0% accuracy and an ROC curve with a significant area-under-the curve (AUC = 0.865, p < 0.001). Conditions with dynamic visual stimulation were the most sensitive to health status. The SOT had an 84.8% accuracy and AUC =0.703 (p = 0.034). CONCLUSIONS: The new VR-based device is a valid measure for detecting balance impairment following mTBI and can potentially replace more expensive and cumbersome equipment. Assessments that test visual-vestibular processing, such as VETS, increase sensitivity to mTBI-related balance deficits, which can be used to guide rehabilitation. Implications for rehabilitation Emerging technology using virtual reality can be economically integrated into the clinical setting for easy testing of postural control in neurologically impaired populations. Tailoring postural assessments to include tasks that rely on visual and vestibular integration will increase the accuracy of detecting balance impairment following mild traumatic brain injury. PMID- 27718643 TI - The effect of whole-body vibration therapy on bone metabolism, motor function, and anthropometric parameters in women with postmenopausal osteoporosis. AB - PURPOSE: To review the research literature on the effectiveness of whole-body vibration (WBV) therapy in women with postmenopausal osteoporosis. METHODS: A systematic review was conducted by two independent reviewers. Mean differences (MDs), standardized mean differences (SMDs), and 95% confidence intervals (CIs) were calculated, and heterogeneity was assessed with the I2 test. The Cochrane risk of bias tool was used to assess the methodological quality of the selected studies. RESULTS: Nine randomized controlled trials involving 625 patients met the inclusion criteria. No significant improvement was found in bone mineral density (BMD) (SMD = -0.06, 95%CI= -0.22-0.11, p = 0.50); bone turnover markers (MD = -0.25, 95%CI= -0.54-0.03, p = 0.08); anthropometric parameters, including muscle mass, fat mass, body mass index (BMI), and weight (SMD = 0.02, 95%CI= 0.16-0.21, p = 0.81); or maximal isotonic knee extensor strength (SMD = 0.16, 95%CI= -0.63-0.95, p = 0.69). However, maximal isometric knee extensor strength improved (SMD = 0.71, 95%CI = 0.34-1.08, p = 0.0002). CONCLUSIONS: WBV is beneficial for enhancing maximal isometric knee extensor strength, but it has no overall treatment effect on BMD, bone turnover markers, anthropometric parameters, or maximal isotonic knee extensor strength in women with postmenopausal osteoporosis. Implication of rehabilitation Osteoporosis is the leading underlying cause of fractures in postmenopausal women, whole body vibration (WBV) has received much attention as a potential intervention for the management of osteoporosis in recent years. Whole body vibration is beneficial for enhancing maximal isometric knee extensor strength in women with postmenopausal osteoporosis. Whole body vibration has no overall treatment effect on bone mineral density, bone turnover markers, anthropometric parameters and maximal isotonic knee extensor strength in women with postmenopausal osteoporosis.

AB - In the present study, the use of bacteriophages to prevent growth and/or biofouling by Pseudomonas aeruginosa PAO1 was investigated in microcosms containing Jet A aviation fuel as the carbon source. Bacteriophages were found to be effective at preventing biofilm formation but did not always prevent planktonic growth in the microcosms. This result was at odds with experiments conducted in nutrient-rich medium, demonstrating the necessity to test antimicrobial and antifouling strategies under conditions as near as possible to the 'real world'. The success of the bacteriophages at preventing biofilm formation makes them potential candidates as antifouling agents for fuel systems. PMID- 27718645 TI - Stroke as a clinical emergency.

AB - INTRODUCTION: Proximal femoral fractures with severe outcome are most common in the increasing group of elderly patients. AIM: Based on the regular data gathered by the EuroHOPE research, the most important aspects and results of the treatment of proximal femoral fractures were studied. METHOD: Data of hospital admissions due to proximal femoral fractures were analyzed. RESULTS: There was a slight increase in the number of hospitalized patients between 2004 and 2009 in Hungary. 88% of the patients received operative treatment, 41% suffered femoral neck fractures. Mortality rates did not change significantly in the analyzed period. Standardized annual mortality rates for patients who had suffered a femoral neck fracture were 28% when prosthesis was implanted; this result was somewhat more favorable than in case of other surgical procedures. Annual mortality rates were higher in the peritrochanteric fracture group where intramedullary nailing was performed (36%). The ratio of operated patients did not differ significantly from international results. Mortality rates in Hungary were significantly less favorable. 30 day standardized mortality rate was 13.6% in 2008, twice as high as the rate in Finland, The Netherlands, Norway, Scotland and Sweden. The 40% mortality rate calculated for 365 days was significantly higher than international results.

This paper presents the most important areas of the development, such as (1) the principles of the methodology, (2) the definition of available databases, code systems, (3) the events to be analysed, (4) the general rules of analyses and indicator development, (5) the exact methodology of data collection, processing, and analysis, (6) the methods of risk adjustment, (7) and the development of the standardised database. The databases which include all information of all patients and healthcare activities serve as perfect inexhaustible data sources for decision makers, healthcare personnel, and researchers. The indicator results of this program serve as starting point for further root cause analysis and development measures based on the results of the abovementioned analyses. Orv.

AB - INTRODUCTION: The EuroHOPE FP7 project analysed the effectiveness and efficiency of stroke care between 2010 and 2014. AIM: The study introduces Hungarian data in comparison with international results and explores the causes of differences. METHOD: The analysis was performed on data available from regular data collection in Finland, The Netherlands, Hungary, Italy, Scotland, and Sweden, with standardized indicators. Hungarian data was analysed between 2005 and 2009, and the international benchmarking in 2008, with multivariate logistic regression analysis for risk adjustment. RESULTS: Stroke incidence in Hungary was the double of the Italian or Finnish results (43.3/10,000 inhabitants), while comorbidities did not differ among countries. In Hungary, 19.9% of patients purchased anti coagulants, one-third of the rate in Finland. One-year mortality in Hungary was 30%, the worst among the countries. Possible causes are inadequate prevention, more severe status of patients, and deficiencies of hospital care and rehabilitation. CONCLUSION: Causal analysis of these results and corrective measurements are recommended. Orv. Hetil., 2016, 157(41), 1635-1641. PMID- 27718662 TI - [Editor's Commentary].

AB - INTRODUCTION: Care provision for very low birth weight and very low gestational age newborns requires high level clinical preparedness. Appropriate care and care management reduce mortality. AIM: To present Hungarian and international outcomes and local regional differences characterizing neonatal care in 2006-2008, based on the results of the EuroHOPE study. METHOD: Hungarian data were created by linking the obstetrics registry with the financing database of the Health Insurance Fund. Resulting from peculiarities of these databases and clinically justified exclusions, 3562 newborns were included. RESULTS: Hungarian risk adjusted 365-day mortality rate was significantly higher than in most of the studied countries. Incidence of diseases correlated with higher mortality risk was highest in Hungary. Mortality in two Hungarian counties was worse than expected based on modelling, while it was better in one county. CONCLUSIONS: Systematic factors might cause these results. Relatively low usage rate of steroid prophylaxis in Hungary might contribute to unfavorable mortality figures. A common unique identifier would help database linkage. Orv. Hetil., 2016, 157(41), 1649-1656. PMID- 27718664 TI - Eye emergencies.

AB - INTRODUCTION: The EuroHOPE research developed the standardised methodology of the analysis of the healthcare process. AIM: The aims of the authors were to analyze the care of acute myocardial infarction in Hungary and to compare the results to those of the partner countries. METHOD: The authors analyzed the application of early and late invasive interventions, medication purchase, and mortality. The results were compared to Finnish, Norwegian, Italian, Scottish and Swedish data. RESULTS: By the end of the observed period, approximately half of the patients received early treatment, which is an internationally acceptable result. Purchase of statins, angiotensin converting enzyme inhibitors, and angiotensin receptor blockers was around 90%, but the application of beta-blockers has decreased for unknown reason. The mortality rate has improved, but it was still significantly worse than that in the partnering countries. One year mortality in the early intervention group was 1.5 times higher, and in the late intervention group was 2 times higher than the second worst results. CONCLUSIONS: The causal analysis concerning the professional activities, operational practices, and the role of the patients in the observed period is highly recommended. For more detailed analysis it is necessary to follow the trends and to separate the diagnoses of ST elevation and non-ST-elevation acute myocardial infarction. Orv. Hetil., 2016, 157(41), 1626-1634.

AB - PURPOSE: Intestinal stoma formation profoundly changes the relationship between a person and their social world. The aim of this study was to understand the experience of living with a new stoma; this paper explores the theme "disrupted social world," highlighting how stoma-forming surgery impacts on individuals' abilities to participate and interact socially over time. METHOD: A longitudinal phenomenological approach. Twelve participants with a new stoma were recruited using purposeful sampling. Data were collected at three, nine and 15 months following surgery through in-depth, unstructured interviews and analysed using a bespoke iterative framework. RESULTS: Three categories were identified: participation in the social environment; interpersonal relationships: changes and challenges; and setting and achieving goals. CONCLUSIONS: Stoma-forming surgery changes the ways people relate to their social environment and connect with others, creating self-consciousness and impeding social confidence and autonomy. Understanding the social implications of stoma-forming surgery can help clinicians to provide responsive and appropriate support to facilitate social rehabilitation. Implications for Rehabilitation Assisting people with a stoma to develop competent stoma self-care skills will promote social adaptation and self acceptance. Clinicians should promote access to others with a stoma, an important source of support for many people adjusting to a new stoma. Graded exposure to social participation can engender feelings of control and confidence for people with a stoma. Clinicians can help individuals with a stoma to set realistic goals for their recovery, while encouraging a range of positive coping strategies. PMID- 27718732 TI - Smoking research.

AB - OBJECTIVE: To compare patients' and physicians' perceptions regarding effectiveness and tolerability of non-insulin hypoglycemic drugs in a cohort of type 2 diabetic patients; to verify whether a possible tridimensional link between effectiveness, tolerability, and adherence affects long-term therapeutic outcomes. METHODS: A two-year observational study was performed in 1389 Type 2 diabetic patients by involving general practitioner clinics and Diabetes Centers. A decimal scale and the Morisky questionnaire were used, respectively, to assess effectiveness and tolerability perceptions, and medication adherence. RESULTS: Physicians perceived therapy as more efficacious compared to their patients: perceived effectiveness was steady for physicians during the study whereas patients' perception not significantly decreased (mean score from >8 to 7.84 +/- 1.69). Physicians assigned higher tolerability scores compared to patients but only at the beginning of the study; interestingly, physicians' tolerability perception was poorer than patients' perception at last follow-up (mean score = 7.57 +/- 1.40 vs. 7.88 +/- 1.84). Favorable (score >7) patients' perceptions about treatment effectiveness and tolerability were associated with higher adherence. Patients showed medium adherence across the study. CONCLUSIONS: A mutual relationship between clinical effectiveness, adverse drug reactions, and adherence has been established, significantly impacting the clinical management of diabetic patients. A careful monitoring of this link by clinicians appears therefore necessary. PMID- 27718745 TI - Pharmacogenetics of neurological and psychiatric diseases at older age: has the time come? AB - INTRODUCTION: In recent years, a number of pharmacological approaches for treating neuropsychiatric conditions at older age have proven to be inadequate. The resulting increased prevalence of therapeutic failures (TF) and a worsening of clinical symptoms often linked to adverse reactions (ADRs), are perhaps among the major causes of the increasing rate of hospitalizations and institutionalizations observed in these patients. Areas covered: This review underlines the importance of pharmacogenetic data to fingerprint the pharmacological treatment of neuropsychiatric late-life conditions throughout the analysis of metabolizing enzymes and transporters of psychotropic drugs, mainly those of the cytochrome P450 (CYP) family. Pharmacodynamic response measures as treatment effects mediated through targets (i.e., receptors in the brain) may also contribute to this image. Expert opinion: CYP genetics is the basis of a continuum on which environmental and physiological factors act, modeling the phenotype observed in clinical practice with advancing age. Furthermore, other specific polymorphic genes influence drug response through differential effects of their functional genetic variants. The known genotypes associated with an altered metabolizer status and drug transporters may help clinical decision making to avoid concomitant treatments, reduce therapeutic attempts and increase drug safety in neuropsychiatric conditions in older age, after controlling for other clinical variables. PMID- 27718746 TI - Incidence and implications of chemotherapy related hand-foot syndrome. AB - INTRODUCTION: Hand-foot syndrome (HFS) is a well-established cutaneous adverse event of certain chemotherapeutic agents, mainly capecitabine, continuously infused 5-fluorouracil, docetaxel and pegylated liposomal doxorubicin. Erythema, dysesthesia, pain, cracking and desquamation located on palms and soles are the most characteristic manifestations. Although HFS is a reversible and non-life threatening clinical condition, it can often affect patient's quality of life significantly, hence necessitating therapeutic modifications or even treatment discontinuation. Areas covered: This is review article on current data regarding the clinical characteristics, grading and management of HFS. Special focus has been given to recent literature studying novel therapeutic strategies. Expert opinion: Early recognition, patient education and supportive measures are considered as the key elements in the management of HFS. Up to date, treatment interruption and dose intensity reduction are the mainstay of HFS management. Many topical formulations and systemic treatment regimens have been proposed, with COX-2 inhibitors being the most promising agents. Nevertheless, large prospective randomized controlled trials are needed in order to agree on solid, evidence-based treatment algorithms. PMID- 27718747 TI - Anti-CD20 monoclonal antibodies in multiple sclerosis. AB - INTRODUCTION: The therapeutic utility of the anti-CD20 monoclonal antibodies (mAbs) is currently being evaluated in multiple sclerosis (MS) in line with the better understanding of the role of B lymphocytes in MS pathogenesis. Area covered: We conducted a literature search using Medline/Pub Med database of basic research and available controlled trials about anti-CD20 mAbs in MS. Additionally, ongoing studies were identified in the ClinicalTrials.gov database. B cells exert multiple inflammatory and regulatory functions playing an important role in MS pathogenesis as is demonstrated by the production of autoantibodies, infiltration of B cells in MS lesions and the formation of ectopic B cell follicle-like structures in meninges, among others. B-cell depletion by anti-CD20 mAbs has been shown to have an impact on these pathogenic mechanisms. The efficacy of three of them, rituximab, ocrelizumab and ofatumumab in MS has been confirmed by placebo-controlled clinical trials demonstrating a significant reduction of the annualized relapsing rate (ARR), new gadolinium-enhancing (GdE) and T2 lesions. There have been no significant safety problems so far but the overall benefit to risk profile is still to be determined. Expert commentary: After recent good results of these agents in MS therapy, questions related to maintenance therapy, markers of response and control of B cells values remain unanswered.

AB - INTRODUCTION: Multiple sclerosis (MS) is a progressive disease of the central nervous system with unknown etiology. It could be associated with severe disability and losses of physical, psychological and social role functioning over time. People with MS share experiences in common with people affected by diseases with a shorter and clearer terminal phase. Therefore, it is appropriate to offer a palliative care approach to people with severe MS and their caregivers. Areas covered: Benefits for severe MS patients and their caregivers were shown when palliative care was included in their care. However, many neurologists show no interest toward palliative care services for people with severe MS. Misunderstandings about the services of palliative care are still prevalent. Expert commentary: When all results are considered, they show that palliative care for severe MS patients may be beneficial. The five-year view will discuss the barriers of palliative care inclusion for people with severe MS. PMID- 27718750 TI - Platelet proteomics applied to the search for novel antiplatelet therapeutic targets. AB - INTRODUCTION: Unwanted platelet activation is associated with numerous diseases, mainly thrombosis-related. In this context, proteomics has emerged as a novel tool with potential for drug target discovery and to scrutinize the effects of antiplatelet drugs. Areas covered: The present review presents the main findings of platelet proteomic studies to date in the context of drug target discovery and perspectives for the future ahead. It includes data and evidences obtained from literature searches on PubMed as well as commentaries derived from the authors' experience and opinions. Expert commentary: Platelet proteomics applied to drug target discovery is a young field. Recent studies have shown promising data, especially in the context of coronary artery disease. However, challenges remain such as establishing definitive guidelines for blood collection and platelet isolation, essential to guarantee data reproducibility. Recent advances in quantitative platelet proteomics should lead to novel studies with higher clinical impact in the near future.

AB - INTRODUCTION: Cystic fibrosis airways disease is characterized by chronic inflammation and infection resulting in bronchiectasis. Published guidelines recommend medications for use by CF patients to maintain lung health. There are conflicting recommendations regarding inhaled bronchodilators. This is primarily because of the interpretation of the available evidence, which suffers from studies using small numbers of subjects, varying doses and durations of treatment, and modest effects on clinically relevant endpoints. Areas covered: Herein we review the available evidence demonstrating the challenge in determining whether bronchodilators have benefit for patients. We examine the potential indications and the current guidance from clinical studies. We highlight the outstanding questions examining bronchodilator use in CF. Expert commentary: The use of bronchodilators in CF remains commonplace despite the lack of solid evidence. Further studies should define key endpoints to determine a role for bronchodilators in light of a substantial treatment burden endured by people with CF. PMID- 27718753 TI - Proteomics approach to identify biomarkers for upper gastrointestinal cancer. AB - INTRODUCTION: The prognosis for patients with upper gastrointestinal cancers remains dismal despite the development of multimodality therapies that incorporate surgery, chemotherapy, and radiotherapy. Early diagnosis and personalized treatment should lead to better prognosis. Given the advances in proteomic technologies over the past decades, proteomics promises to be the most effective technique to identify novel diagnostics and therapeutic targets. Areas covered: For this review, keywords were searched in combination with "proteomics" and "gastric cancer" or "esophageal cancer" in PubMed. Studies that evaluated proteomics associated with upper gastrointestinal cancer were identified through reading, with several studies quoted at second hand. We summarize the proteomics involved in upper gastrointestinal cancer and discuss potential biomarkers and therapeutic targets. Expert commentary: In particular, the development of mass spectrometry has enabled detection of multiple proteins and peptides in more biological samples over a shorter time period and at lower cost than was previously possible. In addition, more sophisticated protein databases have allowed a wider variety of proteins in samples to be quantified. Novel biomarkers that have been identified by new proteomic technologies should be applied in a clinical setting. PMID- 27718754 TI - Special considerations for the treatment of pulmonary exacerbations in children with cystic fibrosis. AB - Introduction Cystic fibrosis (CF) is a disease characterized by recurrent flares of respiratory symptoms, known as pulmonary exacerbations (PExs), which have a cumulative, detrimental effect on lung function decline and overall mortality. Although much research has been done on the effects of PExs in adults with CF, considerably less is known about these events in young children with CF. Areas covered This review describes the typical presentation of PExs in children and their impact on long-term clinical outcomes. Traditional and new monitoring techniques, such as pulmonary function testing using multiple breath washout, radiographic modalities and microbiological screening methods are reviewed. Finally, the choice, administration and duration of antimicrobial treatment as well as the potential use of antiviral therapy is discussed. Expert Commentary Although it is now well recognized that a significant proportion of patients do not recover their lung function following PExs, to date, little progress has been made to improve outcomes in this group. Additional therapies, to complement antimicrobials, may be required to treat infection and inflammation during PExs. Trials of anti-inflammatories such as corticosteroids or other novel drugs need to be done in the setting of PExs with the goal of complete lung function recovery for all individuals with CF.

AB - INTRODUCTION: Colon cancer is common and can be considered a disease of older adults with more than half of cases diagnosed in patients aged over 70 years. Decision-making about treatment with chemotherapy for older adults may be complicated by age-related physiological changes, impaired functional status, limited social supports, concerns regarding the occurrence of and ability to tolerate treatment toxicity, and the presence of comorbidities. This is compounded by a lack of high quality evidence guiding cancer treatment decisions for older adults. Areas covered: This narrative review evaluates the evidence for adjuvant and palliative systemic therapy in older adults with colon cancer. The value of an adequate assessment prior to making a treatment decision is addressed, with emphasis on the geriatric assessment. Guidance in making a treatment decision is provided. Expert commentary: Treatment decisions should consider goals of care, a patient's treatment preferences, and weigh up relative benefits and harms. PMID- 27718756 TI - Drug-eluting balloons in coronary interventions: the quiet revolution? AB - INTRODUCTION: Drug-eluting balloons (DEB) may be considered as a 'quiet revolution' in percutaneous coronary interventions. Early-generation DEB eluting paclitaxel proved to be very effective in animal models to reduce neointimal hyperplasia. Areas covered: Review of DEB efficacy in patients with coronary de novo lesions and in-stent restenosis (ISR). Expert opinion: Many randomized clinical trials and meta-analyses have demonstrated the value of DEB in patients with ISR. In this setting, DEB are safe and effective with clinical and angiographic results superior to plain balloon angioplasty and at least equivalent to first generation drug-eluting stents (DES). In selected 'de novo' lesions (bifurcation lesions, small vessels, diffuse disease, myocardial infarction) DEB represent an attractive alternative although additional evidence in these 'niche' indications is still required before a widespread clinical utilization can be recommended. Recently, new generation DEB have become available, offering interesting new possibilities (paclitaxel and also sirolimus) for coronary interventions. Further studies are required to compare the results of novel generation DEB with those of second-generation DES. PMID- 27718757 TI - Growth hormone delivery devices: current features and potential for enhanced treatment adherence. AB - INTRODUCTION: Adherence to daily growth hormone (GH) injections optimizes treatment benefit; however, adherence rates are sometimes poor. Reasons for poor adherence and persistence are multifaceted. GH injection devices are undergoing continual improvement to enhance adherence. Areas covered: This review evaluates published data on the evolution of GH injection devices to meet patients' needs and preferences, patients' perception of new devices and the projected impact of device developments on adherence. Published studies were identified through literature database searches including EMBASE and PubMed (January 1985-November 2015). Expert opinion: Patient needs and preferences trend towards convenient, easy-to-use devices that enable self-injection, minimize injection preparation steps by reducing the medication reconstitution and storage requirements, and reduce injection pain. In comparative studies, devices that patients considered easier to use than comparator devices were associated with reduced handling errors, fear of injection (needle anxiety/needle phobia) and pain upon needle insertion, and were thus preferred. A combination of the following items are expected to increase patient motivation to better adhere to therapy and improve treatment outcomes: advances in GH injection devices, educating patients regarding injection device and injection technique, and ongoing support from healthcare professionals, including comprehensive education about their condition, medication and expected outcomes. PMID- 27718759 TI - Early drug development: assessment of proarrhythmic risk and cardiovascular safety. AB - INTRODUCTION: hERG assays and thorough ECG trials have been mandated since 2005 to evaluate the QT interval and potential proarrhythmic risk of new chemical entities. The high cost of these studies and the shortcomings inherent in these binary and limited approaches to drug evaluation have prompted regulators to search for more cost effective and mechanistic paradigms to assess drug liability as exemplified by the CiPA initiative and the exposure response ICH E14(R3) guidance document. Areas covered: This review profiles the changing regulatory landscape as it pertains to early drug development and outlines the analyses that can be performed to characterize preclinical and early clinical cardiovascular risk. Expert commentary: It is further acknowledged that the narrow focus on the QT interval needs to be expanded to include a more comprehensive evaluation of cardiovascular risk since unanticipated off target effects have led to the withdrawal of multiple drugs after they had been approved and marketed. PMID- 27718760 TI - Brodalumab for the treatment of psoriasis. AB - INTRODUCTION: Psoriasis is a complex disease in which the alteration of the IL 23/Th17 axis appears to be crucial for its pathogenic mechanisms, and anti-IL17 agents are rapidly becoming important therapeutic tools. Brodalumab, a fully human Chinese hamster ovary cell-derived immunoglobulin G2 (IgG2) anti-IL-17RA monoclonal antibody, is currently the most-developed treatment that binds to the IL-17RA. The authors review and provide updates of efficacy and safety by several studies on brodalumab. Areas covered: A PubMed search was performed for relevant literature. Among the trials of brodalumab, the most common adverse events included nasopharyngitis, headache, upper respiratory tract infection, and arthralgia. Suicidal ideation and completed suicides had been observed in the brodalumab programme, although evidence to date was quoted as not suggesting a causal association. Expert commentary: By blocking the IL-17 receptor A, brodalumab antagonizes signaling from IL-17A, IL-17F, IL-17A/F and IL-25, and this probably contributes to the high efficacy observed in clinical trials. Considering the different therapeutic target and the potential biological implications that blocking IL-17RA instead of IL-17A might have, brodalumab may not necessarily belong to the same class that includes secukinumab and ixekizumab, but it may be classified in a distinct group. PMID- 27718758 TI - Challenges in treating patients with inflammatory bowel disease and concurrent viral hepatitis infection. AB - INTRODUCTION: Inflammatory bowel diseases (IBD) require long-term administration of immunomodulatory treatments to maintain disease remission. Due to the high worldwide prevalence of hepatitis B (HBV) or C (HCV) virus infections, presence of concurrent hepatitis can be a relevant clinical issue to manage when treating IBD. Areas covered: The paper summarizes epidemiological data about IBD and HBV/HCV infection and reviews current knowledge about the natural history of HBV and HCV in the IBD setting, concentrating on risk of hepatitis reactivation during immunosuppressive treatment. Most updated recommendations for management of HBV and HCV infections in IBD patients are discussed. Expert commentary: The development of new drugs for IBD with different molecular targets and the availability of potent and efficacious antiviral drugs for HBV and HCV will simplify management of hepatitis infection in IBD patients in the near future.

PMID- 27718762 TI - Low carbohydrate diet is associated with reduced risk of metabolic syndrome in Tehranian adults. AB - This cohort study was conducted to examine the association of low carbohydrate diet (LCD) score with risk of incident metabolic syndrome (MetS) and its components after 3.6 years of follow-up in 2044 healthy adults within framework of the Tehran Lipid and Glucose Study. The LCD was calculated according to intakes of carbohydrate, monounsaturated fatty acids, refined grains, vegetable protein, fiber, n3/n6 polyunsaturated fatty acids ratio and glycemic load (GL), using a food frequency questionnaire at baseline. In the final model, after adjustment for age, gender, smoking status, physical activity and energy intake, there was significant association between LCD score and fasting plasma glucose (beta: -0.002, 95%CI: -0.005, -0.001), triglycerides (TGs) (beta: -0.002, 95%CI: 0.004, -0.001), BP (beta: -0.001, 95%CI: -0.002, 0.000), WC-BMI (beta: -0.003, 95%CI: -0.005, -0.001) and MetS risk Z-scores (beta: -0.015, 95%CI: -0.021, 0.002). In conclusion, LCD may be associated with a decreased risk of MetS and its components in adults. PMID- 27718763 TI - Inhibitors of phospholipase A2 and their therapeutic potential: an update on patents (2012-2016). AB - INTRODUCTION: The regulation of the catalytic activity of the various phospholipase A2 enzymes is of high importance because these enzymes are involved in various pathological conditions such as arthritis, cardiovascular diseases, neurological diseases, and cancer. Thus, a great effort has been devoted in developing synthetic inhibitors as new agents to treat inflammatory diseases. Some of them have reached clinical trials. Areas covered: This review article discusses the phospholipase A2 inhibitors presented in patent literature from October 2012 to June 2016, their activities in vitro and in vivo as well as the results of clinical trials using synthetic PLA2 inhibitors. Expert opinion: None of the inhibitors studied in clinical trials have reached the market yet. The failure of lipoprotein-associated PLA2 inhibitor darapladib to reduce the risk of major coronary events suggests that this enzyme may be a biomarker of vascular inflammation rather than a causal pathway of cardiovascular diseases. These findings, together with the failure of secreted PLA2 inhibitor varespladib for the treatment of cardiovascular disease, indicate that deeper knowledge on these enzymes is needed. Inhibitors of cytosolic PLA2 are in clinical trials against psoriasis and atopic dermatitis. PMID- 27718765 TI - Vaginal alpha-lipoic acid shows an anti-inflammatory effect on the cervix, preventing its shortening after primary tocolysis. A pilot, randomized, placebo controlled study. AB - INTRODUCTION: Inflammation might be an important underlying cause of preterm birth. Our aim is to explore whether vaginal administration alpha-lipoic acid reduces cervical inflammation and shortening after primary tocolysis. MATERIALS AND METHODS: Singleton pregnancies between 24-30 weeks remaining undelivered after hospitalization for preterm labor were randomly allocated to placebo (20 women, 15 analyzed) or vaginal ALA 400 mg (active ingredient 10 mg) daily (20 women, 17 analyzed) for 30 days. A cervical swab to quantify pro-inflammatory (IL1, IL2, IL6, IL8, TNFalpha) and anti-inflammatory (IL4, IL10) cytokines as well as transvaginal ultrasound cervical length measurement (CL) were performed before and after treatment. RESULTS: The % changes of pro-inflammatory cytokines do not differ between treatment groups, while IL4 significantly increases by vaginal ALA in comparison to placebo (118.0 +/- 364.3% versus 29.9 +/- 103.5%, p = 0.012). Combined anti-inflammatory cytokines show same trend (292.5 +/- 208.5% versus 64.5 +/- 107.4, p = 0.03). CL remains similar in vaginal ALA group (from 23.1 +/- 6.6 to 20.80 +/- 7.9 mm), while it significantly decreased in placebo group (from 20.4 +/- 6.5 to 13.8 +/- 7.5 mm, p < 0.001 versus Baseline; p = 0.003 versus vaginal ALA). CONCLUSION: Vaginal ALA significantly stimulates anti inflammatory ILs in the cervix of undelivered women after a preterm labor episode. This effect is associated with a stabilization of the CL. PMID- 27718766 TI - Value of interim FDG PET/CT for predicting outcome of patients with angioimmunoblastic T-cell lymphoma. AB - Subjects were 45 patients with angioimmunoblastic T-cell lymphoma (AITL) who underwent 2-[18F]-fluoro-2-deoxy-d-glucose (FDG) positron-emission tomography/computed tomography (PET/CT) at baseline and interim after 2-4 cycles. Predictors of progression-free survival (PFS) and overall survival (OS) were assessed. Positive interim PET/CT (Deauville score >=3) was a significant independent predictor of poor PFS (Hazard ratio, 4.42; p=.028), and showed marginal significance to predict OS (p=.065). Less than 60% decrease in the average change of maximum standardized uptake value normalized by lean body mass (SULmax) also was a significant independent predictor of poor PFS (Hazard ratio, 12.96; p=.001) and poor OS (Hazard ratio, 24.11; p=.006). Interim PET/CT has a significant prognostic value for predicting PFS and OS in patients with AITL. Deauville score and percent decrease of SULmax have the potential to be useful parameter in classifying patients into good and poor responders. PMID- 27718767 TI - Neural Activity Elicited by a Cognitive Task can be Detected in Single-Trials with Simultaneous Intracerebral EEG-fMRI Recordings. AB - Recent studies have shown that it is feasible to record simultaneously intracerebral EEG (icEEG) and functional magnetic resonance imaging (fMRI) in patients with epilepsy. While it has mainly been used to explore the hemodynamic changes associated with epileptic spikes, this approach could also provide new insight into human cognition. However, the first step is to ensure that cognitive EEG components, that have lower amplitudes than epileptic spikes, can be appropriately detected under fMRI. We compared the high frequency activities (HFA, 50-150[Formula: see text]Hz) elicited by a reading task in icEEG-only and subsequent icEEG-fMRI in the same patients ([Formula: see text]), implanted with depth electrodes. Comparable responses were obtained, with 71% of the recording sites that responded during the icEEG-only session also responding during the icEEG-fMRI session. For all the remaining sites, nearby clusters (distant of 7[Formula: see text]mm or less) also demonstrated significant HFA increase during the icEEG-fMRI session. Significant HFA increases were also observable at the single-trial level in icEEG-fMRI recordings. Our results show that low-amplitude icEEG signal components such as cognitive-induced HFAs can be reliably recorded with simultaneous fMRI. This paves the way for the use of icEEG-fMRI to address various fundamental and clinical issues, notably the identification of the neural correlates of the BOLD signal. PMID- 27718768 TI - Influence of the Great East Japan Earthquake and the Fukushima Daiichi nuclear disaster on the birth weight of newborns in Fukushima Prefecture: Fukushima Health Management Survey. AB - OBJECTIVE: The Great East Japan Earthquake and Fukushima Daiichi nuclear disaster occurred on 11 March 2011. We investigated the incidence of SGA (small for gestational age) in the Fukushima Prefecture in newborns delivered by women who were pregnant at the time of the disasters and identified any risk factors for SGA. METHODS: Subjects were women who were pregnant at the time of the disasters. Questionnaires were sent to the women who lived in the Hamadori area (seaside and near to the nuclear power plant) at the time of the disasters as well as to a control group of women who lived outside the Hamadori area. The incidence of SGA was compared. Logistic regression analysis was performed to identify the risk factors for SGA. RESULTS: In total, 325(5.6%) women had infants with SGA. Neither area nor the trimester of pregnancy at the time of the disasters influenced the incidence of SGA. Pregnancy-induced hypertension (PIH) was higher in the SGA group. PIH was found to be an independent risk factor for SGA. CONCLUSION: We found no evidence that the Great East Japan Earthquake and the Fukushima Daiichi nuclear disaster increased the incidence of SGA in the Fukushima Prefecture. PMID- 27718769 TI - Podophyllum hexandrum ameliorates endosulfan-induced genotoxicity and mutagenicity in freshwater cyprinid fish crucian carp. AB - CONTEXT: Medicinal plants continue to act as a repository for novel drug leads with novel mechanisms of action. Podophyllum hexandrum Royale (Berberideceae) treats diverse conditions in folk medicine. OBJECTIVE: The antimutagenic potential of P. hexandrum was evaluated against endosulfan-induced clastogenicity in a piscine model by cytogenetic endpoints. MATERIALS AND METHODS: Podophyllum hexandrum rhizomes were subjected to successive solvent extraction. Fish were exposed to hexane, chloroform, ethyl acetate, methanol and aqueous extracts (15 mg/L each) of plant and endosulfan (0.05 mg/L) alone followed by their combination for antimutagenicity estimates. Chromosomal aberrations (CA) were made from kidney cells and micronuclei (MN) slides from peripheral blood erythrocytes at 48, 72 and 96 h. Antioxidant activity was analyzed by the DPPH assay. Phytochemical analyses were carried out using chromatographic and spectroscopic techniques. RESULTS: Endosulfan induced significant (p < .05) MN, authenticated by scanning electron microscopy, and CA in a time-dependent manner. However, methanol and ethyl acetate extracts revealed ameliorating effects. The column eluted methanolic fraction-2 (ME-F2) showed highest reduction profile of 83 and 84% in CA and MN, followed in its extent (73 and 72%) by ethyl acetate fraction-4 (EE-F4). ME-F2 and EE-F4 showed three and six major peaks when analyzed by GC-MS. To explore possible mechanism of action, ME-F2 showed potent antioxidant potential and strong correlation (R2 = .900) with antimutagenic activity, whereas EE-F4 seemed to act through a different mechanism. DISCUSSION AND CONCLUSION: This study confirms the antimutagenic potential of the subject plant with the identification of some novel compounds, justifying their use in folk medicine, and their corresponding benefit to mankind. PMID- 27718771 TI - Bolus feeding has no effect on cerebral hemodynamics, irrespective of gestational age. AB - OBJECTIVE: By multichannel near-infrared spectroscopy, we studied if gestational age has any influence on preterm cerebral hemodynamics, during bolus feeding. METHODS: Oxy-haemoglobin (HbO2), as cerebral blood flow estimate, and the ratio between HbO2 and total haemoglobin (HbO2/HbTot), as cerebral oxygenation estimate, were assessed in 40 stable premature infants, during a 10 min bolus feeding. RESULTS: We found no effect of any of the gestational ages studied (25 34 weeks) either on cerebral blood flow or on oxygenation, during a bolus feeding procedure. CONCLUSIONS: Bolus feeding appears not to affect cerebral hemodynamics of uncritically preterm infants, irrespective of gestational age. PMID- 27718772 TI - Relationship Between Frequent Recreational Cannabis (Marijuana and Hashish) Use and Periodontitis in Adults in the United States: National Health and Nutrition Examination Survey 2011 to 2012. AB - BACKGROUND: Recreational use of cannabis, following its legalization in some countries, poses emergent oral and periodontal health concerns. The objective of this study is to examine the relationship between frequent recreational cannabis (FRC) (marijuana and hashish) use and periodontitis prevalence among adults in the United States. METHODS: Data from the National Health and Nutrition Examination Survey (NHANES) 2011 to 2012 were analyzed. Primary outcome (periodontitis) was defined using the Centers for Disease Control and Prevention/American Academy of Periodontology classification as well as continuous measurements of probing depth (PD) and clinical attachment loss (AL). Exposure of interest was self-reported cannabis use, defined as "FRC use" versus "non-FRC use." Bivariate and multivariable regression models were performed using the entire analytical sample (model 1) as well as those who had never used tobacco (never-users) (model 2). RESULTS: Of 1,938 participants with available cannabis use data and essential covariates, 26.8% were FRC users. Mean number of sites per participant with PD >=4, >=6, and >=8 mm and AL >=3, >=5, and >=8 mm was significantly higher among FRC users than among non-FRC users (mean difference in number of PD sites: 6.9, 5.6, and 5.6; P <0.05; mean difference in number of AL sites: 12.7, 7.6, and 5.6; P <0.05). Average AL was higher among FRC users than among non-FRC users (1.8 versus 1.6 mm; P = 0.004). Bivariate analysis revealed positive (harmful) association between FRC use and severe periodontitis in the entire sample (odds ratio [OR]: 1.7, 95% confidence interval [CI]: 1.3 to 2.4; P = 0.002) as well as in never-smokers (OR: 2.0, 95% CI: 1.2 to 3.5; P = 0.01). This association was retained in multivariable models adjusted for demographics (age, sex, race/ethnicity, and income level), alcohol and tobacco use, diabetes mellitus, and past periodontal treatment (model 1: adjusted OR [aOR]: 1.4, 95% CI: 1.1 to 1.9; P = 0.07; model 2: aOR: 1.9, 95% CI: 1.1 to 3.2; P = 0.03). CONCLUSION: FRC use is associated with deeper PDs, more clinical AL, and higher odds of having severe periodontitis. PMID- 27718773 TI - Difference of hospital charges for stroke inpatients between hospitals with different levels and therapeutic modes in Beijing, China. AB - OBJECTIVES: The present study analyzed the hospital charges for stroke patients in China and determined the factors associated with hospital costs. METHODS: Medical records of hospitalized patients with a primary diagnosis of acute stroke were collected from 121 hospitals in Beijing (2012). Distribution characteristics of hospital charges for different stroke types, hospital levels and types were studied. Factors influencing total hospital charges were analyzed. RESULTS: 60.8% of the 94 906 stroke patients were male and the mean age of these patients was 66.5 +/- 13.2 years. The median length of hospital stay (LOHS) for these patients was 14 d (interquartile range, IQR 9-19). The mean hospital charge per patient was 19 270 Chinese Yuan. Forty-five percent of these charges were for medicine, 18% for laboratory and examination, 16% for material, 15% for therapy, 5% for service and 1% for blood product. The mean hospital charge for patients suffering from hemorrhagic stroke was significantly more than ischemic stroke (34 937 vs. 17 049, p < 0.001), and was significantly more for Level 3 than Level 2 hospitals (23 762 vs. 14 554, p < 0.001). LOHS, hospital level and stroke severity were key determinants of the hospital charge. CONCLUSIONS: Though hospital charges for stroke patients in China were low, it brought a heavy economic burden for the larger stroke population. Medicine accounted for the largest percentage of hospital charges in China. LOHS emerged to be the main predictor of the cost. Decreasing medicine charge and LOHS might be strategies to decrease hospital charges and reduce economic burden of stroke in China. PMID- 27718774 TI - External cephalic version in premature rupture of membranes: a systematic review. AB - BACKGROUND: External cephalic version (ECV) increases the likelihood of a vaginal delivery in patients with breech presentation. Our objective was to determine the rate of cephalic vaginal delivery in women undergoing ECV after PROM. METHODS: We performed a systematic review of all case reports, case series and clinical trials of patients undergoing an ECV after PROM >= 24 weeks. Maternal demographics and outcome data were obtained. The primary outcome was rate of cephalic vaginal delivery. Statistical analysis was performed for continuous outcomes by calculating mean and standard deviations for appropriate variables. RESULTS: The systematic review yielded six papers with 13 case reports and no clinical trials of ECV after PROM. The rate of success to cephalic presentation was 46.1% (six of 13 cases), with a subsequent vaginal delivery rate of 23.1% (three of 13 cases). The rate of umbilical cord prolapse was 33.3% (two of six cases). CONCLUSIONS: ECV after PROM has been reported in 13 cases in the literature. For the cases reported, 46.1% of ECV were successful in turning to cephalic position, but only 23.1% resulted in a vaginal delivery. There was a 33.3% incidence of umbilical cord prolapse. Given the high rate of umbilical cord prolapse, it would be imperative to offer an ECV in the setting of PROM only at an institution that has the ability to perform the indicated emergent cesarean delivery and only after appropriate counseling. PMID- 27718775 TI - Breaking the cycle of hair breakage: pearls for the management of acquired trichorrhexis nodosa. AB - Acquired trichorrhexis nodosa (TN) is a common cause of hair loss for patients of all ethnicities. It is especially prevalent in black patients with tightly curled hair types and can present unique diagnostic and therapeutic challenges due to structural differences in these hair types and the combination of various hair care and styling practices that contribute to hair damage. While scalp biopsies can help rule out other etiologies of hair loss, there is a paucity of histologic findings in acquired TN, making this primarily a clinical diagnosis. Instead of more traditional prescription based therapies, the management of this form of hair loss emphasizes protecting the hair shaft and minimizing further damage through the development of a healthy hair care regimen. This involves appropriate selection and use of cleansing products and conditioning agents that help protect the hair from the insults of daily grooming. This paper will review the current literature on acquired TN and will provide guidelines and recommendations for management by reviewing the different types of cleansing and conditioning products that can be used to prevent and/or halt the progression of hair breakage. PMID- 27718776 TI - Fetal intracranial hemorrhage: sonographic criteria and merits of prenatal diagnosis. AB - PURPOSE: To determine the sonographic criteria for diagnosis of fetal intracranial hemorrhage (ICH), using both gray scale ultrasound, and tomographic ultrasound imaging (TUI). MATERIALS AND METHODS: A prospective multicenter study, recruiting patients at risk of fetal ICH over four years. All cases with fetal ICH had serial ultrasound assessments, including TUI, fetal and postnatal MRIs. RESULTS: Twenty-one patients were diagnosed with fetal ICH, two cases had extracerebral (subdural) hemorrhage, 16 cases had intracerebral (intraventricular) hemorrhage and three cases had combined hemorrhage. The mean gestational age at which they were diagnosed was 29.8 +/- 5.2 weeks. Seventy-six percent of cases had no identifiable risk factors. IUGR was associated with 57.9% of cases. Using grey scale ultrasound, we demonstrated clear cut sonographic criteria for diagnosis of fetal ICH. TUI enabled us to detect some midline cerebral lesions not detected by grey scale 2D ultrasound alone. Fetal and postnatal MRI confirmed those findings. CONCLUSION: Ultrasonography can be used in the detection, classification and monitoring the progression of various types of ICH. TUI is an additional diagnostic tool that might help to detect the exact size, and extent of those lesions. Fetal MRI is not superior, but might aid in the diagnosis. PMID- 27718777 TI - Physical performance measures for predicting outcome in cancer patients: a systematic review. AB - BACKGROUND: Decision making regarding cancer treatment is challenging and there is a need for clinical parameters that can guide these decisions. As physical performance appears to be a reflection of health status, the aim of this systematic review is to assess whether physical performance tests (PPTs) are predictive of the clinical outcome and treatment tolerance in cancer patients. METHODS: A literature search was conducted on 2 April 2015 in the electronic databases Medline and Embase to identify studies focusing on the association between objectively measured PPTs and outcome. No limitations in language or publication dates were applied. RESULTS: The search retrieved 9680 articles, 16 publications were included involving 4187 patients with various cancer types and different treatments. Reported median or mean age varied from 58 to 78 years. Nine studies used the Timed Up & Go (TUG) test, five the Short Physical Performance Battery (SPPB) and five studies focused on gait speed. Poorer TUG, SPPB and gait speed outcome were associated with decreased survival. TUG, SPPB and gait speed were also associated with treatment-related complications. Furthermore, two studies reported an association between poorer TUG and SPPB outcome with higher rates of functional decline. CONCLUSION: PPTs appear to show a significant correlation with survival and these tests could be used as a prognostic tool, particular for older adult patients. A less explicit correlation for treatment-related complications and functional decline was also found. To optimize decision making, future research should focus on developing and validating individualized treatment algorithms that incorporate PPTs in addition to cancer- and treatment-related variables. PMID- 27718778 TI - Long-term refractive status of preterm infants from singleton and multiple pregnancies. AB - OBJECTIVE: To study the effect of plurality on refractive status in former preterm infants at age 8-12 years. METHODS: Refraction was compared in singletons and multiples, in very low birth weight infants (VLBW, <1500 g) at age 6 months and 8-12 years. Preterm infants were compared with a group of term infants. RESULTS: Thirty-seven of 104 (36%) VLBW infants were multiples. Comparison of refraction between singletons and multiples revealed no difference at age 6 months, while at age 8-12 years, multiples had significantly more refractive errors (singletons 28% versus multiples 54% p = 0.01), particularly myopia. In preterms, refractive status at age 6 months and multiple birth were significant predictors of refraction at 8-12 years, while birth weight (BW) and retinopathy of prematurity (ROP) were not predictive. Refractive errors were significantly more common in preterms (37%) than in term-born children (14%) (p = 0.0002). Overall, refraction moved from predominantly hyperopic at 6 months to normal or myopic at age 8-12 years in preterm. CONCLUSIONS: Multiple gestation in preterms is associated with increased risk for refractive errors, particularly myopia in childhood. Refraction in preterms during childhood progresses from hyperopia to myopia. Former preterms have more refractive errors than children born at term born children. PMID- 27718779 TI - Eosinophilia as the presenting sign in pancreatic cancer: an extremely rare occurrence. AB - A case of pancreatic adenocarcinoma diagnosed following work up for eosinophilia is reported. A 68-year-old female was referred to our Hematology clinic for an absolute eosinophil count of 1869 per microliter. No allergic signs or symptoms were reported. Laboratory studies for parasitic infestations autoimmune disease and collagen vascular disease were negative. Computed tomography of the abdomen revealed a mass in the neck of the pancreas with fine needle aspiration biopsy consistent with adenocarcinoma. The patient received one cycle of modified FOLFIRINOX with complete resolution of the eosinophilia. There are rare case reports of tumor-associated blood eosinophilia in solid malignancies. The finding may be indicative of rapid disease progression and poor prognosis. Our case is the third in published English literature with eosinophilia being the initial finding in pancreatic cancer. PMID- 27718780 TI - Preparation and optimization of glyceryl behenate-based highly porous pellets containing cilostazol. AB - The aim of this study was to prepare a highly porous multiparticulate dosage form containing cilostazol for gastroretentive drug delivery. The floating pellets were prepared with glyceryl behenate as a matrix former and camphor as a sublimating agent by extrusion/spheronization and sublimation under vacuum. Granules prepared with sublimation at 60 degrees C displayed a slower dissolution rate and smoother surface morphology than those prepared at lower temperatures. This was unexpected as the reported melting point of glyceryl behenate is higher than 69 degrees C. The DSC study revealed that melting began at a lower temperature owing to the multicomponent property of glyceryl behenate, which led to a sintering effect. The prepared pellets were spherical with unimodal size distribution. They also had porous structures with increased porosity, which led to immediate buoyancy. As cilostazol is a hydrophobic drug that has an erosion-based release mechanism, drug release profile was highly correlated with the percentage of disintegrated pellets. Various excipients were added to the glyceryl behenate-based formulation to increase the floating duration. When hydroxyethyl cellulose was added to the glyceryl behenate-based pellets, acceptable dissolution rate and buoyancy were acquired. This system could potentially be used for gastroretentive delivery of various hydrophobic drugs, which was generally considered difficult. PMID- 27718782 TI - Comparative pharmacokinetics of three SGLT-2 inhibitors sergliflozin, remogliflozin and ertugliflozin: an overview. AB - 1. Several sodium-glucose cotransporter-2 (SGLT-2) inhibitors are in clinical use for the management of type 2 diabetes. The objectives of the current review were: (a) to provide a comparative pharmacokinetics including absorption, distribution, metabolism and excretory (ADME) profiles of three SGLT-2 inhibitors namely: sergliflozin, remogliflozin and ertugliflozin; (b) to provide some perspectives on possible developmental issues. 2. Based on the half-life (t1/2) values observed in humans, the rank order of the three SGLT-2 inhibitors was ertugliflozin (16 h) > remogliflozin (2-4 h) > sergliflozin (1-1.5 h). Therefore, while once a day dosing of ertugliflozin is possible, the other two drugs need to be dosed more frequently. Perhaps, the short t1/2 of sergliflozin may have contributed for its discontinuation. 3. Although there was paucity of published data on the metabolism, transporter related and excretory aspects for sergliflozin, the other two drugs provided a differentiating profile. However, the compiled data suggested that there may be a minimal or no risk of pharmacokinetic drug interaction issues associated with any of the reviewed drugs. 4. Because of the crowded development pipeline and approved SGLT-2 inhibitors, the safety and efficacy of sergliflozin, remogliflozin and ertugliflozin appear to be a key from differentiation perspective. PMID- 27718781 TI - Adjuvant Sunitinib in High-Risk Renal-Cell Carcinoma after Nephrectomy. AB - BACKGROUND: Sunitinib, a vascular endothelial growth factor pathway inhibitor, is an effective treatment for metastatic renal-cell carcinoma. We sought to determine the efficacy and safety of sunitinib in patients with locoregional renal-cell carcinoma at high risk for tumor recurrence after nephrectomy. METHODS: In this randomized, double-blind, phase 3 trial, we assigned 615 patients with locoregional, high-risk clear-cell renal-cell carcinoma to receive either sunitinib (50 mg per day) or placebo on a 4-weeks-on, 2-weeks-off schedule for 1 year or until disease recurrence, unacceptable toxicity, or consent withdrawal. The primary end point was disease-free survival, according to blinded independent central review. Secondary end points included investigator-assessed disease-free survival, overall survival, and safety. RESULTS: The median duration of disease-free survival was 6.8 years (95% confidence interval [CI], 5.8 to not reached) in the sunitinib group and 5.6 years (95% CI, 3.8 to 6.6) in the placebo group (hazard ratio, 0.76; 95% CI, 0.59 to 0.98; P=0.03). Overall survival data were not mature at the time of data cutoff. Dose reductions because of adverse events were more frequent in the sunitinib group than in the placebo group (34.3% vs. 2%), as were dose interruptions (46.4% vs. 13.2%) and discontinuations (28.1% vs. 5.6%). Grade 3 or 4 adverse events were more frequent in the sunitinib group (48.4% for grade 3 events and 12.1% for grade 4 events) than in the placebo group (15.8% and 3.6%, respectively). There was a similar incidence of serious adverse events in the two groups (21.9% for sunitinib vs. 17.1% for placebo); no deaths were attributed to toxic effects. CONCLUSIONS: Among patients with locoregional clear-cell renal-cell carcinoma at high risk for tumor recurrence after nephrectomy, the median duration of disease-free survival was significantly longer in the sunitinib group than in the placebo group, at a cost of a higher rate of toxic events.

AB - Intrauterine growth restriction (IUGR) is defined as growth of fetus below its in utero growth potential. Small for gestational age (SGA) is defined as newborn with birth weight less than 10th centile as per the gestational age, sex and race. There exists major difference between IUGR and SGA. IUGR infants have multiple short-term and long-term complications and IUGR is a silent cause of various morbidities and mortalities in these infants. IUGR/SGA is usually end results of maternal, placental, fetal and genetic causes. With the advance of molecular biology, the list genetic cause of IUGR is increasing and these genetic causes include maternal, placental and fetal genes. Several metabolic and endocrinal causes are also responsible to cause IUGR. In this review, we will try to cover genetic, metabolic and endocrinal factors that are responsible for IUGR.

PMID- 27718784 TI - Nivolumab for Recurrent Squamous-Cell Carcinoma of the Head and Neck. AB - BACKGROUND: Patients with recurrent or metastatic squamous-cell carcinoma of the head and neck after platinum chemotherapy have a very poor prognosis and limited therapeutic options. Nivolumab, an anti-programmed death 1 (PD-1) monoclonal antibody, was assessed as treatment for this condition. METHODS: In this randomized, open-label, phase 3 trial, we assigned, in a 2:1 ratio, 361 patients with recurrent squamous-cell carcinoma of the head and neck whose disease had progressed within 6 months after platinum-based chemotherapy to receive nivolumab (at a dose of 3 mg per kilogram of body weight) every 2 weeks or standard, single agent systemic therapy (methotrexate, docetaxel, or cetuximab). The primary end point was overall survival. Additional end points included progression-free survival, rate of objective response, safety, and patient-reported quality of life. RESULTS: The median overall survival was 7.5 months (95% confidence interval [CI], 5.5 to 9.1) in the nivolumab group versus 5.1 months (95% CI, 4.0 to 6.0) in the group that received standard therapy. Overall survival was significantly longer with nivolumab than with standard therapy (hazard ratio for death, 0.70; 97.73% CI, 0.51 to 0.96; P=0.01), and the estimates of the 1-year survival rate were approximately 19 percentage points higher with nivolumab than with standard therapy (36.0% vs. 16.6%). The median progression-free survival was 2.0 months (95% CI, 1.9 to 2.1) with nivolumab versus 2.3 months (95% CI, 1.9 to 3.1) with standard therapy (hazard ratio for disease progression or death, 0.89; 95% CI, 0.70 to 1.13; P=0.32). The rate of progression-free survival at 6 months was 19.7% with nivolumab versus 9.9% with standard therapy. The response rate was 13.3% in the nivolumab group versus 5.8% in the standard-therapy group. Treatment related adverse events of grade 3 or 4 occurred in 13.1% of the patients in the nivolumab group versus 35.1% of those in the standard-therapy group. Physical, role, and social functioning was stable in the nivolumab group, whereas it was meaningfully worse in the standard-therapy group. CONCLUSIONS: Among patients with platinum-refractory, recurrent squamous-cell carcinoma of the head and neck, treatment with nivolumab resulted in longer overall survival than treatment with standard, single-agent therapy.

PMID- 27718847 TI - Pembrolizumab versus Chemotherapy for PD-L1-Positive Non-Small-Cell Lung Cancer. AB - BACKGROUND: Pembrolizumab is a humanized monoclonal antibody against programmed death 1 (PD-1) that has antitumor activity in advanced non-small-cell lung cancer (NSCLC), with increased activity in tumors that express programmed death ligand 1 (PD-L1). METHODS: In this open-label, phase 3 trial, we randomly assigned 305 patients who had previously untreated advanced NSCLC with PD-L1 expression on at least 50% of tumor cells and no sensitizing mutation of the epidermal growth factor receptor gene or translocation of the anaplastic lymphoma kinase gene to receive either pembrolizumab (at a fixed dose of 200 mg every 3 weeks) or the investigator's choice of platinum-based chemotherapy. Crossover from the chemotherapy group to the pembrolizumab group was permitted in the event of disease progression. The primary end point, progression-free survival, was assessed by means of blinded, independent, central radiologic review. Secondary end points were overall survival, objective response rate, and safety. RESULTS: Median progression-free survival was 10.3 months (95% confidence interval [CI], 6.7 to not reached) in the pembrolizumab group versus 6.0 months (95% CI, 4.2 to 6.2) in the chemotherapy group (hazard ratio for disease progression or death, 0.50; 95% CI, 0.37 to 0.68; P<0.001). The estimated rate of overall survival at 6 months was 80.2% in the pembrolizumab group versus 72.4% in the chemotherapy group (hazard ratio for death, 0.60; 95% CI, 0.41 to 0.89; P=0.005). The response rate was higher in the pembrolizumab group than in the chemotherapy group (44.8% vs. 27.8%), the median duration of response was longer (not reached [range, 1.9+ to 14.5+ months] vs. 6.3 months [range, 2.1+ to 12.6+]), and treatment-related adverse events of any grade were less frequent (occurring in 73.4% vs. 90.0% of patients), as were grade 3, 4, or 5 treatment-related adverse events (26.6% vs. 53.3%). CONCLUSIONS: In patients with advanced NSCLC and PD-L1 expression on at least 50% of tumor cells, pembrolizumab was associated with significantly longer progression-free and overall survival and with fewer adverse events than was platinum-based chemotherapy.

PMID- 27718877 TI - Using reflective writing to gain insight into practice with older people. AB - Much has been written about reflection and its potential to develop not only practitioners but an understanding of nursing practice and therapeutic working through theory that is embedded in practice ( Benner 1984 , Rolfe 1998 , 1996 , Schon 1991 ). A key skill needed by nurses is the ability to work in partnership with older people. To achieve this, it is important for nurses to be able to 'make sense' of their practice, and to understand their contribution in therapeutic working. Structured reflection can therefore be a tool to help nurses gain a greater insight not only into professional practice but into their working relationship with older people.

A four-group, repeated measures experimental design was devised, and a modified version of the Cohen-Mansfield Agitation Inventory was used to record the behavioural responses. The subjects were exposed to calming music (Pachelbel's Canon in D), hand massage (following a research-based protocol), a combination of the two, or no intervention (the control group). Each of the interventions reduced agitation more than the control, and this benefit was sustained. No additional benefit was shown from combining calming music with simultaneous hand massage.

AB - BACKGROUND: Autologous platelet-rich plasma (PRP) is gaining increasing use as a wound healing promoter in a variety of clinical settings, including dentistry. Fresh PRP is often used, necessitating daily draws. The present study investigates the possibility of using stored PRP without having to freeze it by storing PRP under variable conditions and assessing growth factor release as a surrogate marker of continued viability. METHODS: Freshly drawn PRP was stored in oxygen permeable and non-oxygen permeable containers under conditions of constant agitation with or without added prostaglandin, intermittent agitation and no agitation, over an 8-day period. Serial platelet counts, mean platelet volume, platelet distribution width and platelet-large cell ratio, and collagen-induced aggregometry were undertaken. Once collagen-induced aggregation had gone to completion, the plasma was centrifuged to pellet platelet material and the supernatants separated and frozen for batched analysis of released platelet derived growth factor-BB (PDGF-BB). RESULTS: As would be anticipated, platelet counts, percentage aggregation and PDGF-BB levels all reduced over time. Platelet parameters suggested that platelets were more stable in the non-oxygen permeable containers, possibly due to pH drift and a degree of microaggregate formation in the oxygen permeable containers. CONCLUSION: Although platelet integrity and PDGF BB fell over time, the intermittently agitated non-oxygen permeable container appeared to retain better platelet integrity and function, and PDGF-BB release, than other storage conditions, with potential for clinical use for 5-8 days. PMID- 27718889 TI - Masculinities on transnational journeys: sexual practices and risk management among male Chinese immigrants to Canada. AB - Recent critical studies of men and masculinities have encouraged greater consideration of global, international and transnational perspectives and processes. Drawing on interview data from a larger research study of transnationalism and HIV risk through the experiences of recent male Chinese immigrants to Canada, this article examines the intersection of masculinity, sexual practice and the HIV risk in a transnational context. As a gendered strategy, transnational mobility is not only employed by men to cope with the challenges of masculinity enactment encountered in Canada, but also to facilitate sexual activities back in China. By highlighting particular risk factors arising from transnational spaces these men inhabit, the paper reveals the interactive and interconnected effects that such experiences have on Chinese immigrant men's particular behavioural patterns associated with HIV risk, as well as their capacity to respond to this risk. PMID- 27718891 TI - Erythropoietin reduces white matter damage in two-day-old rats exposed to hypoxic/ischemia injury. AB - OBJECTIVE: The aim of the study was to investigate whether erythropoietin (EPO) could protect against white matter damage (WMD) in a preterm equivalent neonatal rat hypoxic-ischemia (HI) model. METHODS: 113 two-day-old male rat pups were divided randomly into three groups: sham-treated, bilateral carotid artery occlusion (BCAO)-treated, BCAO + EPO-treated group. EPO (50 U/10 g body weight) or saline alone was administered intraperitoneally immediately after BCAO surgery. Body weight, brain weight, brain water content, and expression of myelin basic protein (MBP) were assessed at day 1, 3, 7, and 14 after HI insult. Morris water-maze (MWM) test was used to assess neurological behavior from day 31 to 35 after HI insult. RESULTS: Body weights of BCAO + EPO group were greater than those of BCAO group rats (P < 0.05). Specifically, at day 3 and 7 after HI, brain weights of BCAO + EPO-treated rats were higher than BCAO-treated animals (P < 0.05); at day 7 and 14 after HI, MBP of BCAO + EPO-treated rats were higher than BCAO-treated animals (P < 0.05). Similarly, the brain water content at day 3 after HI in BCAO + EPO-treated rats was lower than BCAO-treated animals (P < 0.05). The body weight, brain weight, brain water content, and MBP expression in BCAO + EPO-treated group were comparable to those in the sham-treated group. Spatial learning and memory of BCAO + EPO-treated rats was significantly improved over the BCAO-treated group and was comparable to the sham-operated animals. CONCLUSION: EPO treatment could be a potential intervention in treating WMD for preterm infants.

AB - While the efficacy of mental visual imagery (MVI) to alleviate autobiographical memory (AM) impairment in multiple sclerosis (MS) patients has been documented, nothing is known about the brain changes sustaining that improvement. To explore this issue, 20 relapsing-remitting MS patients showing AM impairment were randomly assigned to two groups, experimental (n = 10), who underwent the MVI programme, and control (n = 10), who followed a sham verbal programme. Besides the stringent AM assessment, the patients underwent structural and functional MRI sessions, consisting in retrieving personal memories, within a pre-/post facilitation study design. Only the experimental group showed a significant AM improvement in post-facilitation, accompanied by changes in brain activation (medial and lateral frontal regions), functional connectivity (posterior brain regions), and grey matter volume (parahippocampal gyrus). Minor activations and functional connectivity changes were observed in the control group. The MVI programme improved AM in MS patients leading to functional and structural changes reflecting (1) an increase reliance on brain regions sustaining a self referential process; (2) a decrease of those reflecting an effortful research process; and (3) better use of neural resources in brain regions sustaining MVI. Functional changes reported in the control group likely reflected ineffective attempts to use the sham strategy in AM. PMID- 27718892 TI - Cephalometric risk factors of obstructive sleep apnea. AB - INTRODUCTION: Previous studies on risk factors of obstructive sleep apnea (OSA) are highly controversial and mostly identifying a few cephalometric risk factors. METHODS: OSA diagnosis was made according to the patients' apnea-hypopnea index (AHI). Included were 74 OSA patients (AHI > 10) and 52 control subjects (AHI <= 10 + free of other OSA symptoms). In both groups, 18 cephalometric parameters were traced (SNA, SNB, ANB, the soft palate's length (PNS-P), inferior airway space, the distance from the mandibular plane to the hyoid (MP-H), lengths of mandible (Go-Gn) and maxilla (PNS-ANS), vertical height of airway (VAL), vertical height of the posterior maxilla (S-PNS), superior posterior airway space (SPAS), middle airway space, distances from hyoid to third cervical vertebra and retrognathion (HH1), C3 (C3H), and RGN (HRGN), the maximum thickness of soft palate (MPT), tongue length (TGL), and the maximum height of tongue). These parameters were compared using t-test. RESULTS: Significant variables were SPAS (p = 0.027), MPT, TGL, HH1, C3H, HRGN, PNS-P, S-PNS, MP-H, VAL, and Go-Gn (all p values <= 0.006). CONCLUSION: OSA patients exhibited thicker and longer soft palates, hyoid bones more distant from the vertebrae, retrognathion, and mandibular plane, higher posterior maxillae, longer mandibles, and smaller superior-posterior airways.

AB - This month's article by Philip Woodrow on assessing blood pressure in older people (p29) makes clear the scale of hypertension among those in middle and later life - almost a third of people over 50 are hypertensive. While this site is not geared specifically towards older people or those who care for them, nurses working in the field will find plenty of the information it contains useful and relevant to their practice. PMID- 27718895 TI - ? AB - It is likely that a good standard of care in a nursing home will result from effective teamworking, but little research in this area has been carried out. This study employed focus group methodology to explore the perceptions of staff working in nursing homes in southern England. All the nurses in the sample described themselves as members of a team. Good communication was stressed as being crucial for effective teamworking, but the hierarchical nature of the teams they described sometimes impeded rather than promoted communication. PMID- 27718896 TI - Challenges in conducting research with acutely ill hospitalized older patients. AB - Older people are major users of acute hospital services, yet the research evidence devoted to issues which affect them does not reflect this situation. In this Australian paper, the authors reflect upon the issues raised by a study they undertook in an acute ward setting. This project used a questionnaire with Likert type scales, followed by open-ended questions, in order to explore perceptions of the relative importance of various aspects of nursing care. Issues encountered when the questionnaire was administered included fatigue, visual impairment and hearing difficulties. The authors stress that many of the problems they had to overcome reflected the changing nature of acute care, rather than the age of the subjects. Intensive treatment regimes and the constant pressure to achieve early discharge have both had a major impact on the opportunities a researcher may have to interview subjects. PMID- 27718897 TI - ? AB - This qualitative study was carried out in one practice in a socially deprived district of inner-city Manchester. Patients' personal accounts of the factors which caused them to accept or reject the offer of vaccination were studied in order to detect common influences. The three most important factors were identified as trust or mistrust in modern medicine, prior experience of vaccination, and the perceived risk from influenza. Current health promotion initiatives encouraging influenza vaccination were largely regarded in a negative light. The authors suggest that future campaigns should place vaccination in a wider context of health maintenance.

This study conducted in Scotland involved data collection from two sources. Semi-structured interviews were undertaken with service providers, including general practitioners and hospital consultants, community psychiatric nurses, and NHS and voluntary sector organisations providing mental health services for older people. The second aspect of the study involved four case studies of South Asian people who had a diagnosis of dementia. The results indicated that professionals had divided opinions on whether specialist services for people from ethnic minority groups should be developed. There was a wide measure of agreement that dementia should be discussed through the use of a 'physical illness' idiom. Service users focused on poor quality of life, and a desperate need for support.

PMID- 27719006 TI - Can we help persons with dementia find their way in a new environment? AB - There has been concern for many years that an older person with dementia is likely to experience increased disorientation if moved from one setting to another. A policy of rebuilding Canadian nursing homes and relocating their residents led these researchers to test a strategy for improving residents' ability to find their way in a new environment. A randomised controlled trial conducted in four nursing homes compared an intervention consisting of the use of a location map and a behavioural training technique called 'backward chaining' with a control group who did not receive it. 'Backward chaining' involved breaking the trip down into smaller sections which were rehearsed individually, with the section of the journey nearest the intended destination (the dining room) being learned first. The results indicated that residents in the treatment group demonstrated an increased ability to find their way to the dining room after one week, but that this effect was not maintained after three months.

AB - I work in a nursing home for older people whose physical and psychological disabilities have come about because of the normal process of ageing. In some clients, however, the ageing process is hastened or complicated by other diseases such as Parkinson's disease (PD). Reading the CPD article has helped me to gain more knowledge of the nature of PD.

In reality, when you have your own business you must be able to turn your hand to a number of jobs and tasks. Joy, our deputy, takes a share of the nursing responsibility from my shoulders, but basically I am responsible, with my husband, for 45 patients, all their needs and for all our staff.

PMID- 27719105 TI - Practice development trials and triumphs. AB - There are strong reasons for developing practice in older people's health care but the concept is complex. Practice development means helping practitioners within their 'real world' context: helping them to find creative and positive ways forward through the demanding, often confusing and draining day-to-day trials and tribulations of practice. Practice development is a continuous journey without a defined end point or final destination. There are always improvements to be made, new ways of seeing things, discoveries to be made and challenges that need to be met ( Pritchard and Cooney 2002 ). PMID- 27719106 TI - The influence of cycling intensity upon cognitive response during inferred practice and competition conditions. AB - In many sport and exercise situations, cognitive performance is required under conditions of high physiological load and high cognitive anxiety. However, few studies have assessed all these components in situ. The current study sought to address this issue. Fourteen adults (9 males, 5 females) completed 2 incremental exercise trials (perceived competition or perceived practice) in a counterbalanced order. Cognitive performance, via a test of visual discrimination, rating of perceived exertion (RPE), heart rate (HR), blood lactate (Bla), and anxiety scores, was recorded at rest, 70% [Formula: see text] and 90% [Formula: see text]. Visual discrimination response times were faster at rest compared to 70% (P = 0.001) and 90% [Formula: see text] (P = 0.002) and at 70% compared to 90% [Formula: see text] (P = 0.04) in the competitive condition. HR post-instructions (P = 0.0001), at 70% (P = 0.001) and 90% [Formula: see text] (P = 0.0001), was significantly higher in competition compared to practice. RPE was higher in the competitive condition compared to the practice condition (P = 0.023). Cognitive anxiety intensity was significantly higher in the competitive condition, at 70% and 90% [Formula: see text] (P = 0.001). This study suggests that cognitive performance is more negatively affected when physiological arousal and cognitive anxiety are at their highest. Coaches and athletes should be mindful of such effects and seek to develop skills to offset such responses or to structure training to better represent competition. PMID- 27719108 TI - 'Basically, it's sorcery for your vagina': unpacking Western representations of vaginal steaming. AB - Vaginal steaming made global headlines in 2015 after its promotion by celebrity Gwyneth Paltrow. One of many female genital modification practices currently on offer in Anglo-Western nations - practices both heavily promoted and critiqued - vaginal steaming is claimed to offer benefits for fertility and overall reproductive, sexual or even general health and wellbeing. We analysed a selection of online accounts of vaginal steaming to determine the sociocultural assumptions and logics within such discourse, including ideas about women, women's bodies and women's engagement with such 'modificatory' practices. Ninety items were carefully selected from the main types of website discussing vaginal steaming: news/magazines; health/lifestyle; spa/service providers; and personal blogs. Data were analysed using thematic analysis, within a constructionist framework that saw us focus on the constructions and rationalities that underpin the explicit content of the texts. Within an overarching theme of 'the self improving woman' we identified four themes: (1) the naturally deteriorating, dirty female body; (2) contemporary life as harmful; (3) physical optimisation and the enhancement of health; and (4) vaginal steaming for life optimisation. Online accounts of vaginal steaming appear both to fit within historico contemporary constructions of women's bodies as deficient and disgusting, and contemporary neoliberal and healthist discourse around the constantly improving subject.

AB - This study evaluated whether exposing junior netball players to greater amounts of competition relevant activity (playing form activity) had an effect on game play outcomes and session involvement. A group-randomised controlled trial in one junior netball club in the Hunter Region, NSW, Australia. Ninety female athletes (mean age = 9.04 years, SD 1.53) were randomised by team (n = 11) into the intervention (n = 41) or 9-week wait-list control (n = 49) condition. The Professional Learning for Understanding Games Education into Sport (PLUNGE into Sport) programme was undertaken in the first half of nine training sessions (9 * 30 min). The intervention exposed athletes to playing form activity through a coach development programme within training sessions. Athletes' decision-making, support and skill outcomes during a small-sided invasion game, and session involvement (pedometer step/min), were measured at baseline and 9-week follow-up. Linear mixed models revealed significant group-by-time intervention effects (P < 0.05) for decision-making (d = 0.4) and support (d = 0.5) during game play, and in-session activity (d = 1.2). An intervention exposing athletes to greater levels of playing form activity, delivered via a coach education programme, was efficacious in improving athlete decision-making and support skills in game play and increasing athlete involvement during sessions.

Introduced as part of the National Service Framework for Older People ( DoH 2000 ), the single assessment process(SAP) has generally been welcomed for its person centred approach and inclusion of older people. It is possible that with appropriate implementation older people will see less duplication and the avoidance of multiple professional assessments, which in turn could improve the care older people receive.

AB - The additional L1 billion funding to go into social services by 2006 has been warmly welcomed, along with the key reforms announced recently by health secretary Alan Milburn ( pages 4 , 6 ). Increased funding is urgently needed to stabilise the care home market, and specifically to increase the fees that social services can offer. Even with the relaxation in the enforcement of environmental standards, the real costs of providing care home places have long exceeded social services fee rates, and L1 billion was exactly the uplift recommended in the recent Joseph Rowntree Foundation analysis of care home provision costs.

AB - The thoughts of Simone de Beauvoir have retained an important place in feminist scholarship. In this Norwegian paper, de Beauvoir's ideas on the different experiences of men and women are applied to the case of stroke rehabilitation. The authors argue that traditional approaches to rehabilitation, which often place it in the context of athletic activity, are less appropriate for women than for men. Indeed, they discuss one Norwegian study in which women patients stayed by their beds reading, while men roamed the corridors discussing their athletic and hunting exploits. The authors argue that such evidence should challenge healthcare professionals to devise rehabilitation regimes which take gender-based preferences into account. 48 references.

AB - This study extends recent coach stress research by evaluating how coaches perceive their stress experiences to affect athletes, and the broader coach athlete relationship. A total of 12 coaches working across a range of team sports at the elite level took part in semi-structured interviews to investigate the 3 study aims: how they perceive athletes to detect signals of coach stress; how they perceive their stress experiences to affect athletes; and, how effective they perceive themselves to be when experiencing stress. Following content analysis, data suggested that coaches perceived athletes able to detect when they were experiencing stress typically via communication, behavioural, and stylistic cues. Although coaches perceived their stress to have some positive effects on athletes, the overwhelming effects were negative and affected "performance and development", "psychological and emotional", and "behavioural and interaction" factors. Coaches also perceived themselves to be less effective when stressed, and this was reflected in their perceptions of competence, self-awareness, and coaching quality. An impactful finding is that coaches are aware of how a range of stress responses are expressed by themselves, and to how they affect athletes, and their coaching quality. Altogether, findings support the emerging view that coach stress affects their own, and athlete performance. PMID- 27719329 TI - ABCB1 polymorphisms and steroid treatment in children with idiopathic nephrotic syndrome. AB - BACKGROUND: The most common cause of nephrotic syndrome (NS) is idiopathic nephrotic syndrome (INS), also called nephrosis. Although most patients respond to steroid therapy, there is unequal response to treatment suggesting the involvement of genetic factors. The current study was conducted to evaluate the influence of two single nucleotide polymorphisms (SNPs) in ABCB1 (C3435T and C1236T) on the steroid treatment response in INS children. MATERIALS AND METHODS: Genotyping of ABCB1 C3435T and C1236T polymorphisms by real time PCR were conducted on 120 INS children, 80 steroid sensitive (SS) and 40 steroid resistant (SR). RESULTS: A significant difference in the distribution of ABCB1 C3435T and C1236T genotypes was observed between SS and SR patients. C1236T polymorphism was associated with steroid resistance in INS children (odds ratio: 2.27, 95 % confidence interval: 1.2-4.4; P = 0.012). The frequency of the T allele was significantly higher in SR than in SS patients (81.2 vs. 65.6%, respectively). The odds ratio for the C3435T polymorphism in response to steroid treatment was smaller than that of the polymorphism C1236T, and did not reach statistical significance (odds ratio: 1.1, 95 % confidence interval: 0.6-1.9; P = 0.77). CONCLUSION: Our results suggested that C1236T polymorphism in ABCB1 gene was associated with steroid resistance. A higher proportion of SR children had C1236T TT genotype and T allele, these patients may require other therapeutic strategies. PMID- 27719379 TI - A model to assess the cost-effectiveness of pharmacogenomics tests in chronic heart failure: the case of ivabradine. AB - Pharmacogenomics (PGx) tests have the potential of improving the effectiveness of expensive new drugs by predicting the likelihood, for a particular patient, to respond to a treatment. The objective of this study was to develop a pharmacoeconomic model to determine the characteristics and the cost effectiveness of a hypothetical PGx test, which would identify patients who are most likely to respond to an expensive treatment for chronic heart failure. For this purpose, we chose the example of ivabradine. Our results suggest that the use of a PGx test that could select a subgroup of patients to be treated with an expensive drug has the potential to provide more efficient drug utilization. PMID- 27719380 TI - Linking Traumatic Childhood Experiences to the Physical Health of Korean Adolescents in Out-of-Home Care through Depression and Anxiety. AB - The main purpose of this study is to assess whether the physical health of Korean adolescents in out-of-home care is affected directly by traumatic childhood experiences and/or indirectly through depression and anxiety. Study participants are 460 adolescents who are included in the first and second wave of the Panel Study on Korean Children in Out-of-Home Care. The data are analyzed using structural equation modeling. Our structural model finds no direct effects of traumatic experiences on physical health. Among the two types of trauma experiences, namely, family instability and violence experiences, only violence experiences affect physical health indirectly through depression and anxiety. Based on the results, practice implications for Korean adolescents in care are discussed. PMID- 27719437 TI - Is three the magic number? The role of ergonomic principles in cross country comprehension of road traffic signs. AB - Road sign comprehension plays an important part in road safety management, particularly for those drivers who are travelling in an unfamiliar country. Previous research has established that comprehension can be improved if signs are designed to adhere to ergonomic principles. However, it may be difficult for sign designers to incorporate all the principles into a single sign and may thus have to make a judgement as to the most effective ones. This study surveyed drivers in three countries to ascertain their understanding of a range of road signs, each of which conformed in varying degrees and combinations to the ergonomic principles. We found that using three of the principles was the most effective and that the most important one was that relating to standardisation; the colours and shapes used were key to comprehension. Other concepts which related to physical and spatial characteristics were less important, whilst conceptual compatibility did not aid comprehension at all. Practitioner Summary: This study explores how road sign comprehension can be improved using ergonomic principles, with particular reference to cross-border drivers. It was found that comprehension can be improved significantly if standardisation is adhered to and if at least three principles are used. PMID- 27719441 TI - Personal Identity and the Schizophrenic Process. PMID- 27719438 TI - The Associations of Naturalistic Classic Psychedelic Use, Mystical Experience, and Creative Problem Solving. AB - Developing methods for improving creativity is of broad interest. Classic psychedelics may enhance creativity; however, the underlying mechanisms of action are unknown. This study was designed to assess whether a relationship exists between naturalistic classic psychedelic use and heightened creative problem solving ability and if so, whether this is mediated by lifetime mystical experience. Participants (N = 68) completed a survey battery assessing lifetime mystical experience and circumstances surrounding the most memorable experience. They were then administered a functional fixedness task in which faster completion times indicate greater creative problem-solving ability. Participants reporting classic psychedelic use concurrent with mystical experience (n = 11) exhibited significantly faster times on the functional fixedness task (Cohen's d = -.87; large effect) and significantly greater lifetime mystical experience (Cohen's d = .93; large effect) than participants not reporting classic psychedelic use concurrent with mystical experience. However, lifetime mystical experience was unrelated to completion times on the functional fixedness task (standardized beta = -.06), and was therefore not a significant mediator. Classic psychedelic use may increase creativity independent of its effects on mystical experience. Maximizing the likelihood of mystical experience may need not be a goal of psychedelic interventions designed to boost creativity.

AB - About 10 heavy elements were determined in 90 samples of baby food collected from Spanish and Serbian market. The results indicated that iron, manganese and copper were most frequently detected. Tin was the predominant toxic element in both Spanish and Serbian samples, with occurrence frequencies of 12.5% and 10.0%, respectively. Element intake for Spanish and Serbian infants were estimated and compared with the recommended reference values, for the majority of elements being lower than one. However, iron and manganese intake through consumption of infant/follow-on formulas were assessed to be higher than the respective daily intakes. Particular attention should be paid to the exposure of infants who consume porridges made of vegetables and fish or chicken, because they may ingest certain elements, particularly arsenic and lead, at levels that exceed the reference toxicological values. Principal component analysis (PCA) was applied to classify and distinguish the different types of baby food. PMID- 27719515 TI - Women, Career Changes, and the New Self.

AB - Substance use is an important clinical issue in the older adult population. As older adults are susceptible to cognitive disorders, the intersection of the fields of substance use and cognitive neuroscience is an active area of research. Prior studies of alcohol use and cognitive performance are mixed, and inconsistencies may be due to under- or over-adjustment for confounders. This article adds to this literature by conducting a secondary analysis of self reported lifetime history of alcohol use and cognitive performance in older adults (n = 133). It was hypothesized that current alcohol users would have poorer cognitive performance compared to never/minimal and former alcohol users. Older adult participants were classified into never/minimal alcohol users, former alcohol users, and current alcohol users. A neurocognitive battery included a global cognitive measure and individual measures of attention, memory, fluency, and executive function. A directed acyclic graph-based approach was used to select variables to be included in the multiple linear regression models. Though unadjusted analyses showed some significant associations between alcohol use and cognitive performance, all associations between alcohol use and cognitive performance were eliminated after adjusting for age, education, sex, race, and smoking pack years. Alcohol drink years were not significantly associated with cognitive performance among current and former alcohol users. These results suggest that lifetime alcohol use is not significantly associated with cognitive performance in older adults after adjustment for key confounders. Inconsistencies in prior studies may be due to uncontrolled confounding and/or unnecessary adjustment of mediators and/or colliders. PMID- 27719518 TI - Men in Extreme Conditions.

AB - To determine which graphic and color combination for a 3-dimensional visual illusion speed reduction marking scheme presents the best visual stimulus, five parameters were designed. According to the Balanced Incomplete Blocks-Law of Comparative Judgment, three schemes, which produce strong stereoscopic impressions, were screened from the 25 initial design schemes of different combinations of graphics and colors. Three-dimensional experimental simulation scenes of the three screened schemes were created to evaluate four different effects according to a semantic analysis. The following conclusions were drawn: schemes with a red color are more effective than those without; the combination of red, yellow and blue produces the best visual stimulus; a larger area from the top surface and the front surface should be colored red; and a triangular prism should be painted as the graphic of the marking according to the stereoscopic impression and the coordination of graphics with the road.

AB - Although job crafting has been linked repeatedly to positive employee and organizational outcomes, its detrimental side has not been well explored. To understand the way dark personality traits affect the type of crafting in which employees engage, this research focuses on two frameworks: the PEN (psychopathy, extraversion, and neuroticism) framework and the Dark Triad (narcissism, psychopathy, and Machiavellianism). In Study 1, we collected data on the PEN traits and job crafting from 155 individuals in various occupations. We found that neuroticism was negatively related to seeking structural job resources, whereas psychoticism was negatively related to seeking social job resources. We also found that extraversion was positively related to seeking structural and social job resources and to seeking challenging job demands. In Study 2, we examined how the Dark Triad traits predicted job crafting among police officers (N = 135). The results showed that narcissism was positively related to seeking social job resources and challenges, whereas psychopathy was negatively related to seeking social resources. Age and narcissism were positive predictors of reducing job demands. We conclude that personality plays an important role when choosing how to craft one's job. We discuss the practical implications of these findings.

AB - Shell cross-linked nanoparticles were fabricated by the complexation of poly(3 methacrylamido phenylboronic acid) (PMAPBA) and thiolated chitosan (chitosan-SH) via boronic acid-related reactions. The formation of PMAPBA/chitosan-SH nanoparticles was confirmed by transmission electron microscopy, dynamic light scattering, and UV spectroscopy. The nanoparticles had a narrow size distribution with a relatively high positive charge density, and the size and zeta potential of the nanoparticles correlated with the chitosan-SH concentration. Furthermore, owing to the cross-linking of the nanoparticle shell, insulin was encapsulated in the nanoparticles with a loading capacity of up to 18%. The release of insulin from the nanoparticles slowed down because of the presence of disulfide bonds and increased with increasing glucose level in the medium. The structure of the released insulin was not distorted. More importantly, the nanoparticles had good cytocompatibility, as demonstrated by in vitro experiments. The simplicity of this strategy along with a high loading capacity, glucose sensitivity, and cytocompatibility of the produced nanoparticles should significantly boost their application in self-regulated insulin delivery.

AB - Concentrations of six phthalates were determined in 69 plastic bottled non alcoholic beverages collected from marketplaces in China. Di-n-butyl phthalate (DBP) and di-(2-ethylhexyl)-phthalate (DEHP) were the most detected compounds with frequencies of 100%. Dimethyl phthalate was found less, with a mean frequency of almost 34%. The samples were divided into seven groups. The frequencies of phthalates in these groups ranged from 6.67% to 100%, which indicated that different types of beverages were differently contaminated by phthalates. DEHP contained the highest mean and median concentrations (1.60 ng g 1 and 0.62 ng g-1), followed by DBP (1.34 ng g-1 and 0.27 ng g-1). For DBP, the highest phthalate concentration of 14.3 ng g-1 was measured. The results of estimated daily intake (EDI) showed that the risk of Chinese adults exposed to these 6 phthalates in beverages examined was lower than the reference doses as suggested by the United States Environmental Protection Agency. The range of EDI values was between 1.77 * 10-4 MUg kg-bw-1 day-1 and 0.478 MUg kg-bw-1 day-1.

AB - AIM AND OBJECTIVE: Tetrahydrobenzo[b]pyran derivatives are considered as a special class in drug research because of their various biological and pharmacological benefiting usages. In the current work, we developed new synthetic methods for the preperation of tetrahydrobenzo[b]pyran derivatives using arylaldehydes 1, malononitrile 2 and dimedonein 3 in the presence of caffeine as catalyst as a cheap, easily accessible, biodegradable and green catalyst. Moreover, for the first time, we have described kinetic results together along with detailed mechanistic studies of the synthetic reaction of a derivative of 4Htetrahydrobenzo[ b]pyran based on a global kinetic analysis methodology using UVvis spectrophotometry apparatus. MATERIAL AND METHOD: Products were characterized by comparison of physical data with authentic samples and spectroscopic data (IR and NMR). Infrared (IR) spectra were recorded on a JASCO FT IR 460 plus spectrometer. 1H nuclear magnetic resonance (NMR) spectra were obtained with a Bruker DRX 400 Advance spectrometer and using deuterated dimethylsulfoxide (DMSO) and acetone as solvents. Thin layer chromatography (TLC) was performed on Silica-gel polygram SILG/UV 254 plates. Rate constants are presented as an average of several kinetic runs (at least 6-10) and are reproducible within +/- 3%. The overall rate of reaction is followed by monitoring the absorbance changes of the products versus time on a Varian (Model Cary Bio-300) UV-vis spectrophotometer with a 10 mm light-path cell. RESULTS: For optimization, the reaction of benzaldehyde (1 mmol), malonitrile (1 mmol) and dimedone (1 mmol) was investigated. The desired results were obtained at 70 degrees C in the presence of (20 mol %) caffeine in H2O: EtOH (2:1). Moreover, the overall order of reaction for the formation of a 4Htetrahydrobenzo[ b]pyran derivative in the presence of caffeine followed second-order kinetics and the partial orders with regard to 4-nitrobenzaldehyde 1, malononitrile 2 and dimedone 3 were one, one and zero, respectively. CONCLUSION: It was observed that the yield was a function of temperature, as the yield increased, the reaction temperature rose. At 70 oC, the product was obtained with an excellent yield and higher temperatures did not increase the reaction yield any more. Also, 20 mol% was elected as a suitable amount of catalyst for this reaction. It is understood from the result that the rate of reaction speeds up in a solvent with a high dielectric constant (H2O/EtOH, 2:1) compared to those with a low dielectric constant (Ethanol and methanol) at all temperatures. In the studied temperature range, the second-order rate constant of the reaction was inversely proportional to the temperature, which was in agreement with the Arrhenius and Eyring equations. It was obvious that the high positive values of the activation parameters leads to a stiff reaction progress. The first step of the proposed mechanism was identified as a rate-determining step (k1) and this was confirmed based on the steady-state approximation.

AB - Parkinson's disease (PD) is a progressive neurodegenerative disorder with prominent motor and non-motor symptoms. Psychosis develops in over 40% of PD patients and it is one of the most distressing symptoms for patients and caregivers alike. Until recently, atypical antipsychotics, clozapine and quetiapine were used to treat psychotic symptoms, but treatment was associated with substantial concerns for side-effects of clozapine and unfounded efficacy for quetiapine. Extensive research has shown that the antipsychotic effect of these drugs could be attributed to serotonin 2a receptor (5-HT2A) triggered mechanisms. A selective 5-HT2A inverse agonist, pimavanserin, has been developed, investigated and has gained approval in April 2016 in the US for the treatment of hallucinations and delusions in PD. In this review we primarily focus on psychosis in PD, the current treatment possibilities and the new, emerging therapy, pimavanserin, a selective 5-HT2A inverse agonist. All articles were reviewed in this topic and indexed in PubMed with keywords: Parkinson's disease psychosis, serotonin 2a receptor inverse agonist, clozapine, quetiapine, pimavanserin.

AB - Injuries to the spinal cord often have devastating physiological impacts due to the organ's vital role in neuro-impulse communications between muscles and the brain. Spinal Cord Injuries (SCIs) have recently been estimated to affect up to 80,000 individuals per year worldwide, with most occurring following a traumatic event. Unfortunately, effective treatments standardised globally for patients with SCIs have not yet been established. For many years, inadequate understanding of the complexities of the Central and Peripheral Nervous Systems and Neurogenesis has limited progression towards effective cures. However, in the last century, scientific advancements have generated new paradigms for medical treatments of SCIs. Basic as well as translational studies have progressed to such an extent that many kinds of protective and regenerative therapeutics are available in clinical trials. In particular, uncovering the mechanisms responsible for controlling the pluripotent state of Human Embryonic Stem Cells (hESCs) was proved vital for recognizing the prospective role in regenerative medicine for SCIs. Elucidating knowledge of neurogenesis alongside hESCs in relation to SCIs has been crucial for critical assessments of the existing translational therapeutic strategies for SCIs. PMID- 27719626 TI - Metabolic Inhibitors as Antiparasitic Drugs: Pharmacological, Biochemical and Molecular Perspectives. AB - BACKGROUND: Human diseases caused by the infectious parasites have been one of the major problems throughout the evolutionary journey. Protozoan and metazoan parasitic infections result in a large number of deaths, disabilities and socio economic loss worldwide to date. Despite the best efforts for developing suitable antiparasitics, these infections take a massive toll on human health. The prevalence of emerging resistance to the existing drugs, lack of efficacy and toxic side effects are as added complications. Being enlisted under 'neglected' category, serious diseases like leishmaniasis, filariasis, trypanosomiasis etc. have failed to draw attention of the governments as well as the pharmaceutical companies. Thus, target specific as well as cost-convenient therapy needs to be employed for the treatment of these diseases and selective targeting of metabolic pathways appears to be the most promising mean. METHODS: In this context, quality works have been explored for screening either anti-metabolic drugs or selective targets in different groups of parasites. Moreover, complete genome sequencing and metabolomic profiling have provided the initiatives to search for new lethal targets in parasites. RESULTS: New metabolic targets are being reported from different organelles and other sub-cellular compartments of parasites such as mitochondrion, kinetoplast, apicoplast, glycosome, hydrogenosome, acidocalcisome, plasma membrane, cytoskeleton, etc. Herein, unique findings achieved in identifying new antimetabolic drugs or targets and studying their molecular mode of actions have been reviewed by incorporating existing and upcoming approaches. CONCLUSION: Considering the alarming scenario of diseases caused by parasites globally, this paper provides a comprehensive review to the scientific community on the development of novel interventions based on metabolic targets to combat the challenges posed by parasites. PMID- 27719627 TI - Role of Reactive Oxygen Species in Premature Ageing of the Female Reproductive Function. AB - Industrial xenobitics, as well as endogenous damaging factors, such as L homocysteine, are a well-known source of reactive oxygen species that disrupt biological processes. Among many others, luteinizing hormone releasing hormone synthesis and secretion mediated by a variety of neurotransmitters, which are under control of the hypothalamus and pineal gland, may be put in peril by reactive oxygen species. Their formation can be one of the reasons for the reproductive function shutdown in ageing as the generic response to the damaging factors independent of their nature. We review recent findings demonstrating the role of reactive oxygen species in disrupting the circadian signal originated in the main pacemaker of the organism, the suprachiasmatic nuclei of the hypothalamus, on its way to the hypothalamic areas responsible for the luteinizing hormone preovulatory surge. PMID- 27719628 TI - Consciousness, Functional Networks and Delirium Screening. AB - BACKGROUND: Consciousness, the medium of sentient thought, requires integrity of functional networks and their connectivity. In health, they function as a co operative but mutually exclusive paradigm of introspection versus external awareness subserved via the Default Mode Network and Task Positive State, respectively. Higher thinking in the conscious state is then segregated according to need. There is research evidence to suggest that functional networks may be impacted in disorders of consciousness and conceptual support for a mechanistic role in delirium. This potentially central aspect of delirium manifestation is relatively unexplored. OBJECTIVE: This article describes the role of disrupted functional networks in delirium. How this relates to current understanding of delirium neurobiology and the ramifications for clinical diagnosis is discussed. METHOD: A review of the role of functional networks, particularly DMN and TPN, has been undertaken with respect to health and delirium. An exploration of how symptoms of delirium may be related to functional network aberrancy has been undertaken. Implications for research and clinical practice in delirium have been presented. RESULTS: In delirium, a disturbance of consciousness, the DMN is pathologically co-activated and functional cortical connectivity is compromised. The clinical correlate is of an experiential singularity where internal and external drivers become indistinguishable, reality and delusion merge and the notion of self is effaced. Our group propose that functional network disruption in conjunction with cortical disconnectivity is central to the mechanism of delirium. Clinical tools may exploit the neurobiology of delirium to improve its diagnosis and an example of such a simple screening instrument (SQeeC) is provided. CONCLUSION: Functional networks are critically disrupted in delirium and may be central to clinical features. A better understanding of the neurobiology of delirium will generate research opportunities with potential for therapeutic gains in detection, diagnosis, and management. PMID- 27719630 TI - Death by Insulin: Management of Self-Harm and Suicide in Diabetes Management. AB - Suicide is the tenth leading cause of death in Americans of all ages. Presence of a chronic medical illness (e.g. Diabetes mellitus) increases the risk of suicide. The goal of this review is to examine the relationship between diabetes and depression, as well as diabetes and suicide. Earlier this year, the U.S. Preventive Task Force (USPTF) escalated their recommendation for depression to include not only routine screening for depression but additional focus on active follow up that requires measurement based care. As a result, it is important that persons with diabetes are also screened for suicidal ideation in the presence of a mood disorder. Due to the higher risk and access to potentially lethal medications in persons with diabetes, risk mitigation procedures should be in place that includes not only depression and suicide screening but also the use of inter-disciplinary teams. Appropriate medical monitoring is essential following a suicide attempt to avoid death particularly because these patients are prone to repeat attempts. PMID- 27719629 TI - Human Umbilical Cord Stem Cell Xenografts Improve Cognitive Decline and Reduce the Amyloid Burden in a Mouse Model of Alzheimer's Disease. AB - INTRODUCTION: Alzheimer's disease (AD) is the most common cause of dementia. The search for new treatments is made more urgent given its increasing prevalence resulting from the aging of the global population. Over the past 20 years, stem cell technologies have become an increasingly attractive option to both study and potentially treat neurodegenerative diseases. Several investigators reported a beneficial effect of different types of stem or progenitor cells on the pathology and cognitive function in AD models. Mouse models are one of the most important research tools for finding new treatment for AD. We aimed to explore the possible therapeutic potential of human umbilical cord mesenchymal stem cell xenografts in a transgenic (Tg) mouse model of AD. METHODS: APP/PS1 Tg AD model mice received human umbilical cord stem cells, directly injected into the carotid artery. To test the efficacy of the umbilical cord stem cells in this AD model, behavioral tasks (sensorimotor and cognitive tests) and immunohistochemical quantitation of the pathology was performed. RESULTS: Treatment of the APP/PS1 AD model mice, with human umbilical cord stem cells, produced a reduction of the amyloid beta burden in the cortex and the hippocampus which correlated with a reduction of the cognitive loss. CONCLUSION: Human umbilical cord mesenchymal stem cells appear to reduce AD pathology in a transgenic mouse model as documented by a reduction of the amyloid plaque burden compared to controls. This amelioration of pathology correlates with improvements on cognitive and sensorimotor tasks. PMID- 27719631 TI - Understanding the Action of Indolizines as Biologically Active Moieties: A Molecular Dynamics Study. AB - BACKGROUND: Indolizines represent a class of heteroaromatic compounds, of pharmacological importance, containing two condensed 5- and 6-memebered rings bridged by a nitrogen atom. Despite indolizine is an important medicinal moiety, a detailed view on the mechanism of action of biologically active indolizines is unavailable. OBJECTIVE: The study of ligand-enzyme affinity is of high interest; description of characteristics (energetic and geometric ones) of ligand binding to the active sites of an enzyme could be useful in understanding the action mechanism of a given ligand on the concerned enzyme. METHOD: After conducting a QSAR study, to predict IC50 (on 15-LO protein from soybeans) of indolizine derivatives and a docking study of indolizines on Beta lactamase and Nicotinamide phosphoribosyltransferase proteins [1], a molecular dynamics analysis was performed on one of the indolizine derivatives, complexed to the above proteins. RESULTS: The performed molecular dynamics study led to the identification of interactions responsible for the stabilization of complexes of the chosen ligand (i.e., indolizine derivative) with the considered enzymes and the specificity of the ligand interaction as well. The structural data and enthalpy values clearly indicate the differences in the behavior of ligand at the active sites of the three investigated enzymes. Among the studied proteins, the hydrophobicity of the active site of Nicotinamide phosphoribosyltransferase seems to be the main factor in promoting the interaction enzyme-ligand, much more manifested in this case, in comparison to the other two proteins Beta lactamase and Nicotinamide phosphoribosyltransferase. CONCLUSION: The present paper discusses a possible mechanism of interaction of an indolizine derivative with three enzyme proteins, providing information for future work in this topic. PMID- 27719632 TI - Miconazole Nitrate-loaded Microparticles For Buccal Use: Immediate Drug Release and Antifungal Effect. AB - BACKGROUND: Miconazole nitrate has been widely employed in treatment of oral mycoses, however your immediate bio-availability and location in the affected area is critical. OBJECTIVE: The aim of this study was to prepare and evaluate Eudragit(r) L100 and Gantrez MS-955 microparticles containing miconazole nitrate for oral delivery. METHODS: Microparticles were prepared by spray-drying method to achieve high encapsulation efficiency and increase the drug solubility. The microparticles were formed containing 10% and 20% of drug on polymer Eudragit(r) L100 (E10 and E20), Gantrez MS-955 (G10 and G20) or their combination (EG10 and EG20). The influence of formulation factors (polymer:drug ratio, type of polymer) on yield percent, encapsulation efficiency, particle size, Fourier-transformed infrared spectroscopy (FTIR), X-ray diffraction, differential scanning calorimetry, in vitro drug release and antifungal activity were investigated. RESULTS: Acceptable yield, micrometer-sized and drug-loading efficiencies higher than 89% were obtained. No change in FTIR assignments was recorded after the microencapsulation procedure. X-ray and differential scanning calorimetry studies revealed amorphous/non-crystalline formulations. Miconazole nitrate microparticles provided a remarkable increase of dissolution rate of the drug. Miconazole nitrate and G10, G20 and EG20 microparticles fitted to biexponential kinetic model, and E10, E20 and EG10 microparticles, monoexponential kinetic model. The antifungal activity test demonstrated that miconazole nitrate microparticles possessed the same anti-Candida albicans activity as the pure drug. CONCLUSION: These results indicate that miconazole nitrate-microparticles are feasible carriers for increased release of miconazole at oral environment. PMID- 27719633 TI - The Efficiency of Tat Cell Penetrating Peptide for Intracellular Uptake of HIV-1 Nef Expressed in E. coli and Mammalian Cell. AB - BACKGROUND: Cell penetrating peptides (CPPs) or protein transduction domains (PTDs) have been known as a new field in cargo delivery. These peptides such as Tat, Pep-1 and Cady-2 are able to deliver genes and biologically active proteins to cytoplasmic compartments via the plasma membrane. METHODS: In current study, the efficiency of pEGFP-N1 eukaryotic vector for expression of HIV-1 Tat- Nef fusion was evaluated in HEK-293T cells using TurboFect transfection reagent. In addition, the recombinant GST-Tat-Nef protein was generated in E. coli and transfected using two amphipathic CPPs (Pep-1 and Cady-2) into mammalian cells. The size and morphology of the CPP/GST-Tat-Nef complexes were evaluated by scanning electron microscopy (SEM), Zetasizer, and SDS-PAGE. The transfection of HIV-1 GST-Tat-Nef protein was also analyzed using SDS-PAGE and western blotting. RESULTS: Our data indicated that the recombinant GST-Tat-Nef protein generated in BL21 strain migrated as a clear band of ~ 52 kDa in SDS-PAGE. The results of SEM and Zetasizer confirmed the formation of protein/ Pep-1 or protein/ Cady-2 nanoparticles less than 200 nm in diameter. Tat CPP fused to Nef protein could deliver the recombinant Nef protein alone and notably by forming the noncovalent complexes with TurboFect, Pep-1 and Cady-2 as detected in western blotting. Moreover, intracellular uptake of Tat-Nef gene and subsequently its expression in mammalian cells was considerably higher than that for Nef gene. CONCLUSION: This data indicated that the Tat gene sequence could also increase the transfection of Nef gene in vitro. Generally, the Tat-Nef interaction led to enhance further gene expression and also protein delivery. PMID- 27719634 TI - Outcomes with Dronedarone in Atrial Fibrillation: What Differences Between Real World Practice and Trials? A Meta-Analysis and Meta-Regression Analysis. AB - Dronedarone was found to have divergent safety profiles in randomized controlled trials (RCT) in term of cardiac death and overall mortality. We decided to evaluate all available evidence on the cardiovascular safety of this drug. A systematic search was made of the MEDLINE and the Cochrane Central Register of Controlled Trials from January 2003 through April 2016 for RCT comparing dronedarone to placebo/active control, to provide the most accurate estimate of the effects of this agent and observational cohort studies (OBS) reporting clinical outcomes in patients treated with dronedarone, according to current guidelines, to obtain a real-life comparator for the findings summarized by RTC analysis. The literature search yielded 2335 papers and after careful review we identified 12 RCT and 7 OBS studies. RCT meta-analysis showed that, despite high heterogeneity, dronedarone was not associated with increased all-cause mortality [OR (Odds Ratio) 1.36, 95%CI (Confidence Interval) 0.79-2.33; p=0.732, I2=57.0%] or cardiovascular mortality [OR 1.51 95%CI 0.74-3.08; p=0.860, I2=64.4%]. OBS studies had a trend toward a better survival with respect to RCT [ES (Effect Size) 2.03, 95%CI 0.53-3.53 vs. ES 3.03, 95%CI 1.23-4.83; p=0.115], reaching the significance when restricted to the cardiovascular mortality [ES 0.52, 95%CI 0.36 0.69 vs. ES 1.86, 95%CI 0.62-3.09; p<0.001]. Two variables, co-adiministration of digoxin and prevalence of non-permanent AF completely abolished the dishomogeneity among the analyzed RCT studies. In conclusion, use of dronedarone for prophylaxis of AF recurrences is not associated with an increased risk of death, either cardiovascular or total, and combination with digoxin should be avoided. PMID- 27719635 TI - Bile Acids as Novel Pharmacological Agents: The Interplay Between Gene Polymorphisms, Epigenetic Factors and Drug Response. AB - BACKGROUND: The field of bile acid research has become tremendously active. Bile acids have been shown to act as signaling molecules that are involved in many metabolic processes, but their role in carcinogenesis is also emerging. METHODS: The aim of this review was to summarize the present knowledge in the innovative field of bile acids pharmacology, to reveal the novel mechanisms of their action, particularly focusing on clinically relevant aspects, and to evaluate the role of both genetic and epigenetic variation in genes encoding bile acid-activated receptors in determining the therapy outcome. RESULTS: Most effects of bile acids are mediated by both nuclear and G protein-coupled receptors. Three natural bile acids have already been registered for the use in humans, but various semi synthetic bile acid analogues with improved pharmacokinetic and pharmacodynamic properties have been developed, which opens up new avenues in pharmacotherapy. Many efforts have been made to evaluate the impact of nuclear receptors on inter individual variation in responses to drugs, since nuclear receptors are significant mediators between environmental stimuli and pharmacokinetics. Genetic variation of bile acid-activated receptors is associated with both benign and malignant diseases, in terms of disease risk and severity, but also with pharmacokinetics and therapy outcome. Furthermore, the activity of these receptors may be masked or amplified by epigenetic modifications. CONCLUSION: Both genetic and epigenetic factors may alter complex and intricate network of bile acid signaling pathways, contributing to the development of several metabolic and non-metabolic diseases and altered activities of drug-metabolizing enzymes and transporters. These polymorphisms and epigenetic modifications may also impact the effectiveness and pharmacokinetics of bile acid analogues, which must be taken into account during the development of these compounds as novel therapeutic agents. PMID- 27719636 TI - RNF5, DAB2 and Friends: Novel Drug Targets for Cystic Fibrosis. AB - BACKGROUND: Deletion of phenylalanine 508 is the most frequent mutation causing cystic fibrosis. It causes multiple defects: 1) misfolding of the protein causing retention at the ER (processing defect); 2) reduced channel activity (gating defect); 3) reduced plasma membrane residency time due to increased internalization rate and defective recycling. METHODS: Druggability of F508del CFTR was demonstrated by several studies. Correctors are molecules able to improve maturation and trafficking to the membrane of F508del- CFTR. Correctors could act as pharmacological chaperones or as proteostasis regulators. Pharmacological chaperones act directly on mutant CFTR, while proteostasis regulators modify the proteostasis environment leading to beneficial effects on CFTR maturation. RESULTS: The use of a single compound is not sufficient to promote a therapeutically relevant F508del-CFTR rescue. Drug therapy for CF will require combinations of correctors exploiting different mechanisms of action, i.e. pharmacological chaperones combined together or with a proteostasis regulator. CONCLUSION: Development of more effective CF drugs could therefore rely on a better understanding of the molecular events underlying CFTR processing/degradation. This review will focus on most promising pathways and related targets for the development of novel CF pharmacotherapies. PMID- 27719638 TI - Targeting Signalling Pathways in Hepatocellular Carcinoma. AB - BACKGROUND: Hepatocellular carcinoma (HCC) represents the most common malignant liver tumor in humans, which incidence and mortality have increased in Europe and United States in the last years. Most patients are diagnosed at an advanced stage, when it is not amenable to curative therapies, so there is an urgent need for new, more effective therapeutic tools and strategies. The molecular mechanisms of hepatocarinogenesis and HCC progression have been increasingly understood with intense research in recent years. METHODS: The goal of this work is to discuss the different signalling pathways as important potential therapeutic targets. RESULTS: Disruption of pathways known to play roles in HCC, such as Wnt/beta-catenin, Hedgehog, RAF/MEK/ERK, tryosine kinase receptor-related pathway, Met-HGF, VEGF/ VEGF and ROR signalling pathways may be seminal for liver oncogenesis. CONCLUSION: This review reveals that oncogenes, especially microRNAs that are conserved across species and interfere with signalling pathways might be used as promising strategies for halting or reversing the progression of HCC. PMID- 27719637 TI - Targeting Notch as a Therapeutic Approach for Human Malignancies. AB - BACKGROUND: Notch is a multifaceted protein that plays a fundamental role in fetal development and tissue homeostasis by directing many cellular functions, including cell growth and differentiation, cell fate determination and regulation of stem cells maintenance. The Notch family consists of four receptors (Notch 1 4) and five ligands (Jagged1-2 and Delta-like 1-3-4) widely expressed in human tissues. Given the crucial contribution of Notch signaling in many physiological processes, it is not surprising that a variety of human malignancies is characterized by a dysregulation of one or more components of this pathway. METHODS: In this review, we are going to provide a broad overview on the role of Notch pathway in solid and hematological malignancies and a survey on possible Notch-directed therapeutic strategies. RESULTS: We present the most recent findings indicating that Notch signaling dysregulation in human cancers may be due to genetic and epigenetic alterations or to the interactions with other oncogenic pathways. Furthermore, Notch activity may have an oncogenic or a tumor suppressor effect. Finally, we describe the latest preclinical and clinical studies concerning the different pharmacological approaches targeting Notch. CONCLUSION: The provided evidence confirms the importance of Notch pathway in human malignancies indicating that a strong rationale exists for the development of a Notch-tailored therapy. PMID- 27719639 TI - Hedgehog Signaling Pathway as Genetic and Epigenetic Target in Ovarian Tumors. AB - BACKGROUND: Hedgehog signaling pathway is a developmental pathway mostly inactive in adult tissues, with the exception of stem cells. It is often found upregulated in various tumors, and associated with cancer stem cell maintenance. METHODS: This review focuses on different aspects of Hedgehog activation in tumors, with special emphasis on ovarian tumors and their treatment. RESULTS: Mutations in pathway components lead to a series of developmental malformations and syndromes. Aberrant activation of the pathway can be caused by mutations, noncanonical transcriptional regulation, or epigenetic changes. CONCLUSION: This pathway is an interesting target in cancer therapy, especially when combined with therapies targeting other signaling pathways. Combination therapy can be used to bypass resistance or to target cancer stem cells in a more efficient way. PMID- 27719640 TI - Casein Kinase II (CK2) as a Therapeutic Target for Hematological Malignancies. AB - BACKGROUND: Casein kinase II (CK2) is a pro-oncogenic protein, which is emerging as a promising therapeutic target in cancer. Recent studies have revealed an important role for CK2 in tumorigenesis. High levels of CK2 are noted in many malignancies including leukemia. Use of CK2 inhibitors in various malignancies including breast, prostate, and lung cancer are being tested. Although many CK2 inhibitors exist, only a few have emerged as selective inhibitors that are potent and effective. CX-4945 is a selective, orallybioavailable small molecule inhibitor, which has shown encouraging results in pre-clinical models of leukemia. METHODS: In this review we will elaborate on the structure and physiological function of the CK2 protein as well as its role in cancer. We will review, in depth, the role of CK2 in leukemia and its mechanisms of tumorigenesis via phosphorylation of the tumor suppressor protein Ikaros. We will discuss both the importance of Ikaros in leukemia suppression and the restoration of Ikaros' tumor suppressor function after CK2 inhibition by CX-4945 (a CK2-specific inhibitor). RESULTS: CK2 is an oncogene that is overexpressed in hematological malignancies. In high risk Pre-B ALL, CK2 phosphorylates Ikaros tumor suppressor and promotes leukemogenesis. Inhibition of CK2 using CX4945 restores Ikaros function and leads to anti leukemic effects in vitro and in pre-clinical leukemia models. CONCLUSION: CK2 is an attractive target in treatment of various cancers. Currently only a few specific CK2 inhibitors are available. Preclinical studies using CK2 inhibitor, CX4945 in high risk pediatric leukemias have shown promising results and warrants further testing in other types of leukemia. PMID- 27719641 TI - Predictive Biomarkers for Linking Disease Pathology and Drug Effect. AB - BACKGROUND: Productivity in drug R&D continues seeing significant attrition in clinical stage testing. Approval of new molecular entities proceeds with slow pace specifically when it comes to chronic, age-related diseases, calling for new conceptual approaches, methodological implementation and organizational adoption in drug development. METHODS: Detailed phenotyping of disease presentation together with comprehensive representation of drug mechanism of action is considered as a path forward, and a big data spectrum has become available covering behavioral, clinical and molecular characteristics, the latter combining reductionist and explorative strategies. On this basis integrative analytics in the realm of Systems Biology has emerged, essentially aiming at traversing associations into causal relationships for bridging molecular disease specifics and clinical phenotype surrogates and finally explaining drug response and outcome. RESULTS: From a conceptual perspective bottom-up modeling approaches are available, with dynamical hierarchies as formalism capable of describing clinical findings as emergent properties of an underlying molecular process network comprehensively resembling disease pathology. In such representation biomarker candidates serve as proxy of a molecular process set, at the interface of a corresponding representation of drug mechanism of action allowing patient stratification and prediction of drug response. In practical implementation network analytics on a protein coding gene level has provided a number of example cases for matching disease presentation and drug molecular effect, and workflows combining computational hypothesis generation and experimental evaluation have become available for systematically optimizing biomarker candidate selection. CONCLUSION: With biomarker-based enrichment strategies in adaptive clinical trials, implementation routes for tackling development attrition are provided. Predictive biomarkers add precision in drug development and as companion diagnostics in clinical practice. PMID- 27719642 TI - Bonafide Targets of Deregulated microRNAs in Non-Small Cell Lung Cancer as Tool to Identify Novel Therapeutic Targets: A Review. AB - BACKGROUND: Non-small-cell lung cancer (NSCLC) is an aggressive neoplasm with a poor survival and novel therapies are urgently needed. The study of deregulated micro- RNAs (dereg-miRs) could constitute a strategy helping to detect specific genes playing a relevant role in the disease. Thus, the oncoproteins encoded by these genes could be exploited as novel therapeutic targets to be inhibited by small molecules, aptamers, or monoclonal antibodies. METHODS: The present review is focused on candidate genes having convincing biological evidences to be both bona fide targets for dereg-miRs and playing a role in NSCLC progression. These genes were evaluated according to the molecular pathway they belong. Moreover, in the attempt to provide an even broader list of candidate therapeutic targets for NSCLC, the full list of genes was analyzed using the online tool Interactome DB. RESULTS: Among the identified targets, some of them belong to p53 or MAP kinase signaling pathways, and others include caspases, MCL1, and BCL2L2 (playing a role in apoptosis), ZEB1, ZEB2, and USP25 (epithelial-to-mesenchymal transition), EZH2, SOX9, and HOXA5 (differentiation), Paxillin, LIMK1 and MTDH (cytoskeleton remodeling), and HDGF (angiogenesis). In addition, other targets, such as TIMP-2, PIM-1, and components of the IGF-signaling pathways were suggested following the interactome analysis. CONCLUSION: Studies on dereg-miRs helped to identify a set of genes whose encoded proteins could constitute candidates for future therapeutic approaches. PMID- 27719643 TI - Curcumin: An Effective Inhibitor of Interleukin-6. AB - Curcumin is apolyphenolic compound found in the dietary spice turmeric. Anti inflammatory effects of turmeric have been known for centuries and extensive studies over the last two to three decades revealed that curcumin is a key component in the anti-inflammatory effects of turmeric. Chronic inflammation is involved in the various pathologic states and curcumin demonstrated therapeutic effects in different inflammation-related diseases in various in vivo, in vitro and human based studies through regulation of different signaling molecules including transcription factors, chemokines, cytokines, tumor suppressor genes, adhesion molecules and microRNAs. Interleukin-6 (IL-6) plays important roles in various events during inflammation including regulation of antibody (and autoantibody) production, activation of T cells, differentiation of B cells, increased production of acute-phase proteins, hematopoiesis and angiogenesis, vascular permeability, and osteoclast differentiation. IL-6 is also involved in pathogenesis of different inflammatory diseases. There are numerous studies demonstrating association of down-regulation of IL-6 and/or inhibition of IL-6 signaling with therapeutic effects of curcumin suggesting a role for modulation of IL-6 in anti-inflammatory effects of curcumin. Moreover, curcumin can be considered as potential therapy against IL-6 involved pathologic stats. In this narrative review, the in vitro, experimental and clinical studies that report association of IL-6 inhibition and therapeutic effects of curcumin are discussed. PMID- 27719644 TI - PPAR Agonists, Atherogenic Dyslipidemia and Cardiovascular Risk. AB - Peroxisome proliferator-activated receptors (PPAR) are implicated in the pathology of several metabolic diseases including obesity, diabetes, and atherosclerosis. PPAR agonists exert multiple lipid modifying actions which are beneficial to the prevention of atherosclerosis. Such benefits in lipid lowering actions include improvements in atherogenic dyslipidemia that seems to be particularly expressed in individuals at higher cardiovascular (CV) risk. In addition, the favorable effects of PPAR agonists on different cardio-metabolic parameters are established in several metabolic conditions, such as diabetes mellitus, insulin resistance, and heightened systemic inflammation. The goal of this review is to summarize the current evidence on PPAR agonists and their effects on atherogenic dyslipidemia and CV risk. The main findings indicate that PPAR agonists improve not only the lipid profile, but also lipoprotein subfractions associated with atherogenic dyslipidemia and other CV markers. However, future prospective studies are required to establish the long-term effects of such therapies on atherogenic lipoproteins and their benefit on CV outcomes. PMID- 27719645 TI - Impact of Statin Therapy on Plasma Vitamin D Levels: A Systematic Review and Meta Analysis. AB - BACKGROUND: During recent years, treatment with statins has been suggested to induce several effect on bone status and vitamin D metabolism, interpreted as statins pleiotropic effects. Actually, the available data are not conclusive and the characteristics of this association remains unclear. AIM: The purpose of this meta-analysis was therefore to investigate the possible effect of statins therapy on vitamin D serum levels based on the reported results from RCTs and observational studies. METHODS: PubMed-Medline, SCOPUS, Web of Science and Google Scholar databases were searched to identify studies evaluating the impact of statins on plasma vitamin D concentrations from inception to September 16, 2015. A systematic assessment of bias in the included randomized controlled trials was performed using the Cochrane criteria. A random-effects model (using DerSimonian Laird method) and the generic inverse variance method were used for the heterogeneity of studies in terms of demographic characteristics of populations being studied and also differences in study design and type of statin being studied. Sensitivity analysis was conducted using the leave-one-out method. RESULTS: Following a multiple database search, 1422 published studies were identified; among these, 7 studies were found to be eligible and included in the systematic review and meta-analysis. Our meta-analysis of data from seven studies (including 5 RCTs) did not indicate any significant effect of statins treatment on plasma vitamin D levels. CONCLUSION: Further well-designed trials are necessary to confirm these results and to define better a possible relationship between statins and vitamin D levels. PMID- 27719646 TI - Therapeutic Potential of Phytochemicals in Combination with Drugs for Cardiovascular Disorders. AB - The incidence of cardiovascular disorders is increasing worldwide. Heart disease is the leading cause of death for both men and women. High blood pressure, high low-density lipoprotein cholesterol level, and smoking are key risk factors for heart disease. Other medical conditions such as diabetes, overweight, obesity and lifestyle can put people at a higher risk for coronary heart disease. The preventive measures based on the common drugs may help reduce the risk of cardiovascular diseases. The present review highlights the contributions of therapeutic potential of phytochemicals in management of cardiovascular diseases. However, the delivery efficiency of therapeutic agents can be enhanced in order to improve the efficacy of phytochemicals as a therapeutic agent. The oral administration of phytochemicals as therapeutic agents is a common approach. The review highlights the recent development of natural products for the complementary treatment of cardiovascular diseases. These findings indicate that the combination of therapeutic drugs and natural products may improve the treatment efficacy of therapeutic agents. PMID- 27719647 TI - Cardiovascular Toxicity of Cyclooxygenase Inhibitors and Promising Natur a l Substitutes. AB - Non-steroidal anti-inflammatory drugs (NSAIDs) are a group of drugs which are used for a wide variety of diseases including pain and inflammatory conditions such as osteoarthritis, rheumatoid arthritis, musculoskeletal disorders, and other comorbid complications. However, this group of drugs have undesirable effects such as peptic ulcer, bleeding and renal failure. Some of these side effects are associated with or caused by generation of oxidative stress. Following the withdrawal of a cyclo-oxygenase-2 (COX-2) inhibitor drug, rofecoxib (VIOXX(r)) due to cardiovascular complications, scientists suggested that natural COX-2 inhibitors might provide valuable alternatives to COX inhibitors. Although, most of medicinal plants reduce pain and inflammation in a similar manner to synthetic medications, however, they often have fewer side effects and are better tolerated. The present review other than focusing on cardiovascular and some other complications of NSAIDs, is trying to introduce the natural alternative remedies for these medications. PMID- 27719648 TI - Therapeutic Interventions for Advanced Glycation-End Products and its Receptor- Mediated Cardiovascular Disease. AB - Advanced glycation end products (AGEs) are heterogeneous group of molecules formed from nonenzymatic reaction of reducing sugars with amino group of proteins, lipids, and nucleic acid. Interaction of AGEs with its cell-bound receptor (RAGE) results in generation of oxygen radicals, nuclear factor kappa beta, proinflammatory cytokines and cell adhesion molecules, and is involved in the pathophysiology of cardiovascular diseases (CVD). Circulating soluble forms of RAGE (sRAGE) and endo-secretory RAGE (esRAGE) compete with RAGE for ligand binding and function as a decoy. This paper describes the endogenous and exogenous (high dietary AGEs, and cooking food under high dry heat, elevated pH, and longer period) sources of AGEs. AGERAGE- mediated CVD includes atherosclerosis, coronary artery disease, carotid artery disease, hypertension, peripheral vascular diseases, heart failure, cardiomyopathy, and microangiopathy. The therapeutic interventions with reduction in AGEs and RAGE, and elevation in sRAGE has been reported for the treatment of AGE-RAGEmediated CVD. Reduction in levels of AGEs can be achieved by reduction in consumption of food containing low amount of AGEs, cooking food at low temperature, moist heat, and shorter duration. AGE formation can be reduced with drugs, vitamins and stoppage of cigarette smoking. Statins, telmisartan, and curcumin have been used for suppression of RAGE. Statins, ACE-inhibitors, Rosiglitazone and vitamin D have been used to increase levels of sRAGE. Finally exogenous administration of sRAGE can be helpful in amelioration of CVD. In conclusion, AGE-RAGE-mediated CVD could be attenuated with reduction in consumption of AGEs, suppression of RAGE and elevation of sRAGE. PMID- 27719649 TI - Precision Medicine and a Patient-Orientated Approach: Is this the Future for Tracking Cardiovascular Disorders? AB - The latest statistics from the 2016 heart disease and stroke statistics update shows that cardiovascular disease is the leading global cause of death, currently accounting for more than 17.3 million deaths per year. Type II diabetes is also on the rise with out-of-control numbers. To address these pandemics, we need to treat patients using an individualized patient care approach, but simultaneously gather data to support the precision medicine initiative. Last year the NIH announced the precision medicine initiative to generate novel knowledge regarding diseases, with a near-term focus on cancers, followed by a longer-term aim, applicable to a whole range of health applications and diseases. The focus of this paper is to suggest a combined effort between the latest precision medicine initiative, researchers and clinicians; whereby novel techniques could immediately make a difference in patient care, but long-term add to knowledge for use in precision medicine. We discuss the intricate relationship between individualized patient care and precision medicine and the current thoughts regarding which data is actually suitable for the precision medicine data gathering. The uses of viscoelastic techniques in precision medicine are discussed and how these techniques might give novel perspectives on the success of treatment regimes of cardiovascular patients are explored. Thrombo-embolic stroke, rheumathoid arthritis and type II diabetes are used as examples of diseases where precision medicine and a patient-orientated approach can possibly be implemented. In conclusion it is suggested that if all role players work together by embracing a new way of thought in treating and managing cardiovascular disease and diabetes will we be able to adequately address these out-ofcontrol conditions. PMID- 27719650 TI - The Insular Cortex and Takotsubo Cardiomyopathy. AB - Transient left ventricular dysfunction in patients under emotional stress, also known as Takotsubo cardiomyopathy, has been recognized as a distinct clinical entity. Recent studies have supported the concept notion that the cardiovascular system is regulated by cortical modulation. A network consisting of the insular cortex (Ic), anterior cingulate gyrus, and amygdala plays a crucial role in the regulation of the central autonomic nervous system in relation to emotional stress such as anxiety, fear and sadness. Because the Ic is located in the region of the middle cerebral arteries, its structure tends to be exposed to a higher risk of cerebrovascular disease. Ic damage has been associated with myocardial injury, increased brain natriuretic peptide, and the incidence of Takotsubo cardiomyopathy. Because Ic damage has been associated with increased sympathetic nervous system activity, Ic damage is suggested to have a pivotal role in the pathophysiology of Takotsubo cardiomyopathy. In this review, we focus on the role of the Ic as a mediator for the cardiovascular system in relation to emotional stress, and we summarizes the current knowledge on the relationships between the Ic and Takotsubo cardiomyopathy. PMID- 27719651 TI - Effect of Sibutramine on Plasma C-Reactive Protein, Leptin and Adipon ectin Concentrations: A Systematic Review and Meta-Analysis of Randomized Contr olled Trials. AB - Sibutramine is an anti-obesity medication whose effects on weight loss have been widely explored. Moreover, limited number of studies also evidenced its correlates on adipokines and proinflammatory markers; however, their results have not been conclusive. Hence, a systematic review and meta-analysis of available evidence was conducted in order to calculate the effect size of sibutramine therapy on C-reactive protein (CRP), leptin and adiponectin concentrations. Seven randomized clinical trials with a total of 601 subjects met the eligibility criteria. Random effect meta-analysis evidenced a significant decrease in plasma levels of CRP and leptin (weighted mean difference [WMD] -15.58%, 95% confidence interval [95%CI]: -28.84, -2.33, p=0.021 and WMD -9.25, 95%CI: -15.73, -2.78, p=0.005, respectively) and increase of adiponectin (WMD 9.86%, 95%CI: 1.76, 17.96, p=0.017) following sibutramine therapy. Subgroup analysis showed a greater CRP-lowering effect of sibutramine with doses <15 mg/day (WMD -17.26%, 95%CI: 31.02, -3.5, p=0.014) compared with doses .15 mg/day (WMD 6.01%, 95%CI: -43.38, 55.40, p=0.811). In meta-regression analysis, changes in CRP were found to be independent of baseline or percentage change in body mass index. These results suggest a significant improvement of plasma CRP, leptin and adiponectin levels following treatment with sibutramine. Possible impacts and relevance of these alterations on cardiovascular risk profile remain to be clarified, especially in post-hoc analyses of sibutramine outcome trials among people without pre-existing cardiovascular disease. PMID- 27719652 TI - Non-Invasive Assessment of Liver Injury in Non-Alcoholic Fatty Liver Disease: A Review of Literature. AB - NAFLD (Non-Alcoholic Fatty Liver Disease) is an increasingly significant public health issue, regarded as the most relevant liver disease of the twenty-first century. Approximately 20%-30% of NAFLD subjects develop a NASH (Non-Alcoholic Steato-Hepatitis), a condition which can potentially evolve to liver cirrhosis and hepatocellular carcinoma. For these reasons a proper evaluation of liver damage is a key point for diagnosis and prognosis and liver biopsy still remains the "gold standard" procedure both for discrimination between steatosis and steatohepatitis and assessment of the degree of liver fibrosis. Nonetheless, given it is an invasive, painful and costly procedure, a great research efforts have been made in order to develop non-invasive methods for the assessment of NAFLD presence and/or severity by serum markers and imaging techniques. In this review we aimed to perform a comprehensive review of the literature about strengths and weaknesses of the main tools available for the non-invasive assessment of NAFLD patients. PMID- 27719653 TI - Licochalcone B Arrests Cell Cycle Progression and Induces Apoptosis in Human Breast Cancer MCF-7 Cells. AB - BACKGROUND: Recent patent of licochalcone B (LCB) as an antiinflammatory agent has been developed. Emerging evidence shows that LCB may be a promising alternative compound with anti-cancer activities. However, the anticancer mechanism of LCB in MCF-7 cells has not been fully investigated. OBJECTIVE: We aimed to unearth the anti-cancer effect and mechanism of LCB in MCF-7 cells. METHOD: Cell proliferation activity and cell-cycle progression were determined by sulforhodamine B assay and flow cytometry, respectively. The mRNA and protein levels of cell cycle-related proteins and apoptosis-associated proteins were examined by RT-qPCR and western blot, respectively. Mitochondrial membrane potential (MMP) was measured by flow cytometry after JC-1 staining. RESULTS: We found that LCB inhibited MCF-7 cells proliferation in a concentration- and time dependent manner. Moreover, LCB-treatment led to S phase arrest in MCF-7 cells, which could be elucidated by the decreased mRNA and protein levels of Cyclin A, Cdk2 and Cdc25 A, and the increased protein level of p21. LCB also induced such apoptosis morphology as phosphatidylserine externalization, chromatin condensation and DNA fragmentation. Moreover, LCB led to the loss of MMP, resulting in the release of cytochrome C. The above apoptotic events were supported by the fact that LCB upregulated the mRNA and protein levels of Caspase 3, Caspase 9 and Bax, and downregulated the mRNA and protein level of Bcl-2, which was triggered by the increased p53 protein level in LCB-treated MCF-7 cells. CONCLUSION: These findings suggested that LCB could be a promising agent for treatment of human breast cancer. PMID- 27719654 TI - Leveraging Structural Diversity and Allosteric Regulatory Mechanisms of Protein Kinases in the Discovery of Small Molecule Inhibitors. AB - Protein kinases are versatile molecule switches that govern functional processes in signal transduction networks and regulate fundamental biological processes of cell cycle and organism development. The continuous growth of biological information and a remarkable breath of structural, genetic, and pharmacological studies on protein kinase genes have significantly advanced our knowledge of the kinase activation, drug binding and allosteric mechanisms underlying kinase regulation and interactions in signaling cascades.. Structural and biochemical studies of the genetic and molecular determinants of protein kinases binding with inhibitors have been the cornerstone of drug discovery efforts in clinical oncology leading to proliferation of effective anticancer therapies. Recent advances in understanding allosteric regulation of protein kinases have fueled unprecedented efforts aiming in the discovery of targeted and allosteric kinase inhibitors that can combat cancer mutants and are at the forefront of the precision medicine initiative in oncology. Despite diversity of regulatory scenarios underlying kinase functions, dimerization-driven activation is a common mechanism of allosteric regulation that is shared by many protein kinase families, most notably ErbB and BRAF kinases that play a central role in growth factor signaling and human disease. In this review, we focused on structural, biochemical and computational studies of the ErbB and BRAF kinases and discuss how diversity of the structural landscape for these kinase genes and dimerization dependent mechanisms of their regulation can be leveraged in the design and discovery of kinase inhibitors and allosteric modulators of kinase activation. The lessons from this analysis could inform discovery of specific targeted therapies and robust drug combinations for cancer treatment. PMID- 27719655 TI - Cardiac Biomarkers: Invasive to Non-invasive Assessments. AB - Cardiovascular disease (CVD) is a major threat to global health, estimated to be the cause 30 % (17.3 million in 2008) of deaths every year, and the number of deaths caused by CVD is expected to increase further, reaching 23.3 million by 2030. Hence, there is a growing demand for simpler sample extraction, rapid screening results, and intervention of the subsequent analysis in emergency units. In this paper, we reviewed CVD biomarkers in blood- and saliva-based specimens. The history of cardiac biomarkers indicates that in the beginning, cardiac troponin I (cTnI) was a widely accepted 'gold standard' marker due to its high specificity and selectivity. Considering the advantages of salivary-based cardiac biomarkers, we examined correlations between non-invasive (salivary) and invasive (blood) diagnoses, and it was found that C-reactive protein (CRP) provides a better correlation. Despite the low abundance of salivary CRP, several reports displayed the detection limit down to pg/ml using existing technologies. Thus, salivary CRP has the potential to be used for future forefront diagnostics for the early assessment of cardiac risks. PMID- 27719656 TI - Oil Palm Defensin: A Thermal Stable Peptide that Restricts the Mycelial Growth of Ganoderma boninense. AB - Plant defensins are plant defence peptides that have many different biological activities, including antifungal, antimicrobial, and insecticidal activities. A cDNA (EgDFS) encoding defensin was isolated from Elaeis guineensis. The open reading frame of EgDFS contained 231 nucleotides encoding a 71-amino acid protein with a predicted molecular weight at 8.69 kDa, and a potential signal peptide. The eight highly conserved cysteine sites in plant defensins were also conserved in EgDFS. The EgDFS sequence lacking 30 amino acid residues at its N-terminus (EgDFSm) was cloned into Escherichia coli BL21 (DE3) pLysS and successfully expressed as a soluble recombinant protein. The recombinant EgDFSm was found to be a thermal stable peptide which demonstrated inhibitory activity against the growth of G. boninense possibly by inhibiting starch assimilation. The role of EgDFSm in oil palm defence system against the infection of pathogen G. boninense was discussed. PMID- 27719657 TI - GENIUS In Silico Screening Technology for HCV Drug Discovery. AB - The various reported in silico screening protocols such as molecular docking are associated with various drawbacks as well as benefits. In molecular docking, on interaction with ligand, the protein or receptor molecule gets activated by adopting conformational changes. These conformational changes cannot be utilized to predict the 3D structure of a protein-ligand complex from unbound protein conformations rigid docking, which necessitates the demand for understanding protein flexibility. Therefore, efficiency and accuracy of docking should be achieved and various available/developed protocols may be adopted. One such protocol is GENIUS induced-fit docking and it is used effectively for the development of anti-HCV NS3-4A serine protease inhibitors. The present review elaborates the GENIUS docking protocol along with its benefits and drawbacks. PMID- 27719660 TI - Neuroprotective and Neurotoxic Implications of alpha7 Nicotinic Acetylcholine Receptor and Abeta Interaction: Therapeutic Options in Alzheimer's Disease. AB - BACKGROUND: Alzheimer's disease, a neurodegenerative disorder, is characterized by accumulation of amyloid beta (Abeta) plaques, neurofibrillary tangles and loss of cholinergic neurons. LITERATURE REVIEW: The localization of Abeta plaques particularly in the cholinergic neuron-rich areas has led to the discovery that Abeta binds to alpha7 nicotinic acetylcholine receptors (nAChRs) with very high affinity. This discovery has led to extensive exploration of the possible outcomes of this binding, ranging from the subcellular signaling pathways to its effects on behavioral and cognitive functions. Intriguingly, there are conflicting reports about the effects of this Abeta and alpha7 nAChR interaction; a few studies report a neuroprotective role of this interaction while others claim that it is neurotoxic. CONCLUSION: This review focuses on the neurotoxic and neuroprotective effects of Abeta and alpha7 nAChR interaction and its implications on different cell signaling pathways and other physiological functions. Moreover, the implications this interaction might have on Alzheimer's disease therapy are also discussed. PMID- 27719659 TI - Cardioprotective Effects of the Polyphenol Hydroxytyrosol from Olive Oil. AB - BACKGROUND: The Mediterranean diet includes olive oil as its primary source of fat. This diet is frequently associated to longevity and a lower incidence of chronic diseases due to its biological activities and health effects. Apart from oleic acid, olive oil contains many bioactive components including polyphenols that have been reported to exert antioxidant and anti-inflammatory activities. Polyphenols may almost in part be responsible for the protective effects against cardiovascular diseases associated with olive oil. OBJECTIVE: To review and discuss the available literature on hydroxytyrosol effects as a cardioprotective agent. Moreover, we also discuss the chemistry, nutritional aspects and bioavailability of hydroxytyrosol. RESULTS: Hydroxytyrosol is one of the major phenolic compounds in olive oil and has demonstrated strong radical-scavenging properties. Several studies have been performed in order to look further into the effects of the polyphenol hydroxytyrosol in relation to cardiovascular events and illnesses in animal trials and in vitro. However, no clinical trials have focused on the specific action of hydroxytyrosol and cardiovascular diseases, although some are being undertaken to look at olive oil or olive leaf extract properties. CONCLUSION: Hydroxytyrosol from olive oil exerts antioxidant, anti-inflammatory, anti-platelet aggregation and ati-atherogenic activities in in vitro and animal models. However, its possible therapeutic use in humans requires additional clinical trials. PMID- 27719658 TI - Aspirin Intolerance: Experimental Models for Bed-to-Bench. AB - Aspirin is the oldest non-steroidal anti-inflammatory drug (NSAID), and it sometimes causes asthma-like symptoms known as aspirin-exacerbated respiratory disease (AERD), which can be serious. Unwanted effects of aspirin (aspirin intolerance) are also observed in patients with food-dependent exercise-induced anaphylaxis, a type I allergy disease, and aspirin-induced urticaria (AIU). However the target and the mechanism of the aspirin intolerance are still unknown. There is no animal or cellular model of AERD, because its pathophysiological mechanism is still unknown, but it is thought that inhibition of cyclooxygenase by causative agents leads to an increase of free arachidonic acid, which is metabolized into cysteinyl leukotrienes (cysLTs) that provoke airway smooth muscle constriction and asthma symptoms. As the bed-tobench approach, to confirm the clinical discussion in experimental cellular models, we have tried to develop a cellular model of AERD using activated RBL-2H3 cells, a rat mast cell like cell line. Indomethacin (another NSAID and also causes AERD), enhances in vitro cysLTs production by RBL-2H3 cells, while there is no induction of cysLTs production in the absence of inflammatory activation. Since this suggests that all inflammatory cells with activation of prostaglandin and cysLT metabolism should respond to NSAIDs, and then I have concluded that aspirin intolerance should be separated from subsequent bronchoconstriction. Evidence about the cellular mechanisms of NSAIDs may be employed for development of in vitro AERD models as the approach from bench-to-bed. PMID- 27719661 TI - Neuroprotective Effects of Ellagitannins: A Brief Review. AB - BACKGROUND: Neurodegenerative diseases are increasingly inevitable as the population gets older, with enormous socio-economic costs. The World Health Organization (WHO) has reported that by 2040, neurodegenerative diseases will overtake cancer to become the second leading cause of death, after cardiovascular disease. OBJECTIVE: Herein, this review outlines the neuroprotective effects and clinical implications of ellagitannins, a class of hydrolysable tannins, for the management and treatment of neurodegenerative disorders. RESULTS: Recent investigations suggest that the combination of genes and environmental toxins may contribute to the risk of developing neurodegenerative disorders. Thus, intervention strategies aimed at reducing exposure to risk factors such as life style, smoking, diet, vitamin deficiencies, chemical exposure and pollution are warranted. Modulation of dietary components including ellagitannins, as a therapeutic strategy to slow down or attenuate the progression of neuronal degeneration has become a focus of interest in the last few decades. CONCLUSION: Polyphenolic plant phytochemicals and ellagitannins in particular, contain an array of neuroprotective properties useful to improve human health and protect against neurodegeneration. PMID- 27719663 TI - Astrocytes as an HIV Reservoir: Mechanism of HIV Infection. AB - If we have any hope of achieving a cure for HIV infection, close attention to the cell types capable of getting infected with HIV is necessary. Of these cell types, astrocytes are the most ideal cell type for the formation of such a reservoir. These are long-lived cells with a very low turnover rate and are found in the brain and the gastrointestinal tract. Although astrocytes are evidently resistant to infection of cell-free HIV in vitro, these cells are efficiently infected via cell-tocell contact by which immature HIV virions bud off lymphocytes and have the ability to directly bind to CXCR4, triggering the process of fusion in the absence of CD4. In this review, we closely examine the evidence for HIV infection of astrocytes in the brain and the mechanisms for viral entry and regulation in this cell type, and discuss an approach for controlling this viral reservoir. PMID- 27719664 TI - Overview on the Tricks of HIV Tat to Hit the Blood Brain Barrier. AB - HIV infection among AIDS patients is associated with dysfunctions in the central nervous system (CNS) at the late stages of the disease. HIV Tat protein is released extracellularly from the productively infected cells and play important role in successful HIV replication and activates the neighboring uninfected cells in the bystander fashion. The structural flexibility of Tat protein is one of the unique features, responsible for the diverse functions. The RNA binding ability and interacting domains are very important characteristic of the HIV-Tat protein. HIV Tat protein adversely affects the integrity of the blood brain barrier by a variety of mechanisms. Such compromise in the integrity of the blood brain barrier could affect the neuro-immune interactions within the brain, which results to the neuroinflammation. PMID- 27719665 TI - Plastid Molecular Pharming II. Production of Biopharmaceuticals by Plastid Transformation. AB - BACKGROUND: Higher plants have been used in medicine throughout human history. METHOD: While traditional medicinal uses relied on compounds produced naturally by plants, recent advances have enabled the use of plant-based factories to produce diverse agents including pharmaceuticals, antibiotics, and vaccines. The genes responsible for the production of these substances can be either transiently expressed in plants or integrated into their nuclear genome or plastid genome (plastome) by genetic transformation. This review focuses on the application of plastid transformation of higher plants to produce biopharmaceuticals for human applications that are neither antibiotics nor vaccines. Plastid transformation has several advantages over nuclear transformation and represents a minimal risk of transgene contamination to the environment via pollen grains because plastid genes are in most species normally maternally inherited and thus absent from pollen. Other advantages of sitedirected plastid insertion via homologous recombination include strong gene expression due to the plastid genome's high copy number and resistance to silencing, and the ability to achieve multi-gene expression with a single insertion step. RESULTS: Compared to bacterial systems, plant-based bioreactors offer lower production costs, lower risks of human pathogen contamination, and the possibility of exploiting post-translational modification. CONCLUSION: Consequently, sustainable plant systems based on different species, plastids, and tissues could become an important source of added value in pharmaceutical production. PMID- 27719666 TI - Cannabis: A Treasure Trove or Pandora's Box? AB - BACKGROUND & OBJECTIVE: Cannabis is one of the earliest cultivated plants. Cannabis of industrial utility and culinary value is generally termed as hemp. Conversely, cannabis that is bred for medical, spiritual and recreational purposes is called marijuana. The female marijuana plant produces a significant quantity of bio- and psychoactive phytocannabinoids, which regained the spotlight with the discovery of the endocannabinoid system of the animals in the early 90's. Nevertheless, marijuana is surrounded by controversies, debates and misconceptions related to its taxonomic classification, forensic identification, medical potential, legalization and its long-term health consequences. METHOD: In the first part, we provide an in-depth review of the botany and taxonomy of Cannabis. We then overview the biosynthesis of phytocannabinoids within the glandular trichomes with emphasis on the role of peculiar plastids in the production of the secreted material. We also compile the analytical methods used to determine the phytocannabinoid composition of glandular trichomes. In the second part, we revisit the psychobiology and molecular medicine of marijuana. RESULTS & CONCLUSION: We summarize our current knowledge on the recreational use of cannabis with respect to the modes of consumption, short-term effects, chronic health consequences and cannabis use disorder. Next, we overview the molecular targets of a dozen major and minor bioactive cannabinoids in the body. This helps us introduce the endocannabinoid system in an unprecedented detail: its up-todate molecular biology, pharmacology, physiology and medical significance, and beyond. In conclusion, we offer an unbiased survey about cannabis to help better weigh its medical value versus the associated risks. PMID- 27719667 TI - Plastid Molecular Pharming I. Production of Oral Vaccines via Plastid Transformation. AB - BACKGROUND: Vaccines produced in plants have opened up new opportunities in vaccination. OBJECTIVE: Among the various categories of vaccines, the recombinant vaccine is generally regarded as the most economical and safest type because it cannot cause disease and does not require large-scale cultivation of pathogens. Due to the low cost of their cultivation, plants may represent viable alternative platforms for producing subunit vaccines. Genetic engineering of plastids is the innovation of the last three decades and has numerous benefits when compared to nuclear transformation. Due to the high level of expression, oral vaccines produced in transplastomic plants do not have to be purified as they can be consumed raw, which, therefore, reduces the cost of preparation, transportation and handling of the vaccines. Oral vaccination also excludes the risk of other infections or contaminations, while compartmentation of the plant cell provides an excellent encapsulation to the antigen within the plastid. RESULTS & CONCLUSION: Herein we review the main biotechnological and immunological aspects of the progress achieved in the field of plastid derived edible vaccines during the last decade. As there is a public debate against genetically modified crops, the advantages and limitations of oral vaccines are also discussed. PMID- 27719668 TI - Chlorophylls and their Derivatives Used in Food Industry and Medicine. AB - BACKGROUND & OBJECTIVE: Thylakoids and chloroplasts harbor several vital metabolic processes, but are most importantly associated with photosynthesis. The undisturbed functioning of this process necessitates the ceaseless synthesis of photosynthetic pigments, including closed tetrapyrroles such as chlorophylls (Chls). Chls probably represent the most abundant natural pigment molecules which are via photosynthesis not only crucial for the autotrophic production of food sources for heterotrophic organisms but have also contributed to oxygen production essential for aerobic metabolism. This review first briefly discusses the physico-chemical properties, biosynthesis, occurrence, in vivo localization and roles of the different Chl pigments. Then we provide a detailed overview of their potential applications in the food industry and medicine. These include the use of Chls and their derivatives (different chlorophyllins) as food colorants (identified as E140 and E141 in the European Union). METHOD: Different sources used for industrial extraction as well as different factors influencing pigment stability during processing are also critically reviewed. The problems surrounding the nomenclature, the production and the composition of different chlorophyllin mixtures are also discussed. RESULTS & CONCLUSION: Finally, a comprehensive overview of the health benefits and potential medicinal applications of these pigments and the future directions of research in these fields are provided. PMID- 27719669 TI - Endocrine disruption: In silico perspectives of interactions of di-(2 ethylhexyl)phthalate and its five major metabolites with progesterone receptor. AB - BACKGROUND: Di-(2-ethylhexyl)phthalate (DEHP) is a common endocrine disrupting compound (EDC) present in the environment as a result of industrial activity and leaching from polyvinyl products. DEHP is used as a plasticizer in medical devices and many commercial and household items. Exposure occurs through inhalation, ingestion, and skin contact. DEHP is metabolized to a primary metabolite mono-(2-ethylhexyl)phthalate (MEHP) in the body, which is further metabolized to four major secondary metabolites, mono(2-ethyl-5 hydroxyhexyl)phthalate (5-OH-MEHP), mono(2-ethyl-5-oxyhexyl)phthalate (5-oxo MEHP), mono(2-ethyl-5-carboxypentyl)phthalate (5-cx-MEPP) and mono[2 (carboxymethyl)hexyl]phthalate (2-cx-MMHP). DEHP and its metabolites are associated with developmental abnormalities and reproductive dysfunction within the human population. Progesterone receptor (PR) signaling is involved in important reproductive functions and is a potential target for endocrine disrupting activities of DEHP and its metabolites. This study used in silico approaches for structural binding analyses of DEHP and its five indicated major metabolites with PR. METHODS: Protein Data bank was searched to retrieve the crystal structure of human PR (Id: 1SQN). PubChem database was used to obtain the structures of DEHP and its five metabolites. Docking was performed using Glide (Schrodinger) Induced Fit Docking module. RESULTS: DEHP and its metabolites interacted with 19-25 residues of PR with the majority of the interacting residues overlapping (82-95 % commonality) with the native bound ligand norethindrone (NET). DEHP and each of its five metabolites formed a hydrogen bonding interaction with residue Gln-725 of PR. The binding affinity was highest for NET followed by DEHP, 5-OH-MEHP, 5-oxo-MEHP, MEHP, 5-cx-MEPP, and 2-cx-MMHP. CONCLUSION: The high binding affinity of DEHP and its five major metabolites with PR as well as a high rate of overlap between PR interacting residues among DEHP and its metabolites and the native ligand, NET, suggested their disrupting potential in normal PR signaling, resulting in adverse reproductive effects. PMID- 27719670 TI - Characterization of left and right atrial function in healthy volunteers by cardiovascular magnetic resonance. AB - BACKGROUND: Left and right atrial function show a different pattern in advanced age in order to maintain adequate ventricular filling. It has been shown that left atrial (LA) function has a prognostic value in a number of heart conditions. Cardiovascular magnetic resonance (CMR) provides high quality images of the left and right atria using high temporal resolution steady state free precession (SSFP) cine sequences. We used SSFP cines to characterize atrial function in healthy, normotensive, volunteers. METHODS: We measured maximum, preatrial contraction and minimum left and right atrial volumes in 120 healthy subjects after careful exclusion of cardiovascular abnormality (60 men, 60 women; 20 subjects per age decile from 20 to 80 years). Data were generated from 3 dimensional modeling, including tracking of the atrioventricular ring motion and time-volume curves analysis. With those measurements, all the usual parameters for left and right atrial function were calculated. RESULTS: Gender had significant influence on some parameters of left and right atrial conduit and booster pump function. Age significantly influenced the majority of parameters of both left and right atrial function, with typically lower reservoir and conduit functions and higher booster pump function, both in males and females belonging to older age groups. CMR normal ranges were modelled for clinical use with normalization, where appropriate, for body surface area and gender, displaying parameters with respect to age. CONCLUSIONS: CMR normal reference ranges for components of left and right atrial function are provided for males and females for a wide age range.

AB - Biomedical journals continue to be the single most important conduit for disseminating biomedical knowledge. Unlike clinical medicine, where evidence is considered fundamental to practice, journals still operate largely in a 'black box' mode without sufficient evidence to drive their practice. We believe there is an immediate need to substantially increase the amount and quality of research by journals to ensure their practice is as evidence based as possible. To achieve this goal, we are proposing the development of an international 'best practice journal research network'. We invite journals and others to join the network. Such a network is likely to improve the quality of journals. It is also likely to address many unanswered questions in publication science, including peer review, which can provide robust and generalizable answers. PMID- 27719672 TI - Human sex hormone-binding globulin as a potential target of alternate plasticizers: an in silico study. AB - BACKGROUND: Currently, alternate plasticizers are used to replace phthalate plasticizers in children's toys, medical equipments and food packaging, due to the adverse effects of phthalate compounds on human health and laws prohibiting their use. Current information regarding the safety and potential adverse effects of alternate plasticizers is limited and recent studies have found alternate plasticizers to display similar characteristics to those observed in phthalate plasticizers. This study was undertaken to evaluate and predict the potential endocrine disrupting activity of the three most commonly used alternate plasticizers: di(2-ethylhexyl)terephthalate (DEHT), tris(2 ethylhexyl)trimellitate (TOTM), and diisononyl hexahydrophthalate (DINCH) against human sex hormone-binding globulin (SHBG) using in silico approaches. MATERIALS AND METHODS: The crystal structure of human SHBG (Id: 1D2S) was retrieved from Protein Data Bank. PubChem database was searched for the structures of alternate plasticizers, DEHT, TOTM, and DINCH. Docking was performed using Glide (Schrodinger) Induced Fit Docking module. RESULTS: Induced Fit Docking of three alternate plasticizer compounds indicated that each of the three compounds fitted well into the steroid binding pocket of SHBG. Docking displays showed interactions of alternate plasticizers with 25-30 amino-acid residues of SHBG; 18 20 amino residues overlapped between the natural ligand, DHT, and the three compounds (commonality of 82-91 %). The hydrogen-bonding interaction of the amino acid residue, Asn-82, of SHBG was also present in displays of DHT and all the three alternate phthalates. The binding affinity of all the three alternate phthalates was higher than DHT; maximum in DINCH followed by TOTM and DEHT. CONCLUSION: Our results suggested that the three alternate plasticizers have potential to engage the important interacting residues of SHBG and thus interfere in its steroid homeostatic function. PMID- 27719673 TI - Health care provider knowledge and routine management of pre-eclampsia in Pakistan. AB - BACKGROUND: Maternal mortality ratio is 276 per 100,000 live births in Pakistan. Eclampsia is responsible for one in every ten maternal deaths despite the fact that management of this disease is inexpensive and has been available for decades. Many studies have shown that health care providers in low and middle income countries have limited training to manage patients with eclampsia. Hence, we aimed to explore the knowledge of different cadres of health care providers regarding aetiology, diagnosis and treatment of pre-eclampsia and eclampsia and current management practices. METHODS: We conducted a mixed method study in the districts of Hyderabad and Matiari in Sindh province, Pakistan. Focus group discussions and interviews were conducted with community health care providers, which included Lady Health Workers and their supervisors; traditional birth attendants and facility care providers. In total seven focus groups and 26 interviews were conducted. NVivo 10 was used for analysis and emerging themes and sub-themes were drawn. RESULTS: All participants were providing care for pregnant women for more than a decade except one traditional birth attendant and two doctors. The most common cause of pre-eclampsia mentioned by community health care providers was stress of daily life: the burden of care giving, physical workload, short birth spacing and financial constraints. All health care provider groups except traditional birth attendants correctly identified the signs, symptoms, and complications of pre-eclampsia and eclampsia and were referring such women to tertiary health facilities. Only doctors were aware that magnesium sulphate is recommended for eclampsia management and prevention; however, they expressed fears regarding its use at first and secondary level health facilities. CONCLUSION: This study found several gaps in knowledge regarding aetiology, diagnosis and treatment of pre-eclampsia among health care providers in Sindh. Findings suggest that lesser knowledge regarding management of pre-eclampsia is due to lack of refresher trainings and written guidelines for management of pre eclampsia and presentation of fewer pre-eclamptic patients at first and secondary level health care facilities. We suggest to include management of pre-eclampsia in regular trainings of health care providers and to provide management protocols at all health facilities. TRIAL REGISTRATION: NCT01911494. PMID- 27719674 TI - Age, environment, object recognition and morphological diversity of GFAP immunolabeled astrocytes. AB - BACKGROUND: Few studies have explored the glial response to a standard environment and how the response may be associated with age-related cognitive decline in learning and memory. Here we investigated aging and environmental influences on hippocampal-dependent tasks and on the morphology of an unbiased selected population of astrocytes from the molecular layer of dentate gyrus, which is the main target of perforant pathway. RESULTS: Six and twenty-month-old female, albino Swiss mice were housed, from weaning, in a standard or enriched environment, including running wheels for exercise and tested for object recognition and contextual memories. Young adult and aged subjects, independent of environment, were able to distinguish familiar from novel objects. All experimental groups, except aged mice from standard environment, distinguish stationary from displaced objects. Young adult but not aged mice, independent of environment, were able to distinguish older from recent objects. Only young mice from an enriched environment were able to distinguish novel from familiar contexts. Unbiased selected astrocytes from the molecular layer of the dentate gyrus were reconstructed in three-dimensions and classified using hierarchical cluster analysis of bimodal or multimodal morphological features. We found two morphological phenotypes of astrocytes and we designated type I the astrocytes that exhibited significantly higher values of morphological complexity as compared with type II. Complexity = [Sum of the terminal orders + Number of terminals] * [Total branch length/Number of primary branches]. On average, type I morphological complexity seems to be much more sensitive to age and environmental influences than that of type II. Indeed, aging and environmental impoverishment interact and reduce the morphological complexity of type I astrocytes at a point that they could not be distinguished anymore from type II. CONCLUSIONS: We suggest these two types of astrocytes may have different physiological roles and that the detrimental effects of aging on memory in mice from a standard environment may be associated with a reduction of astrocytes morphological diversity. PMID- 27719675 TI - Impact of HIV infection on the presentation, outcome and host response in patients admitted to the intensive care unit with sepsis; a case control study. AB - BACKGROUND: Sepsis is a prominent reason for intensive care unit (ICU) admission in patients with HIV. We aimed to investigate the impact of HIV infection on presentation, outcome and host response in sepsis. METHODS: We performed a prospective observational study in the ICUs of two tertiary hospitals. For the current analyses, we selected all patients diagnosed with sepsis within 24 hours after admission. Host response biomarkers were analyzed in a more homogeneous subgroup of admissions involving HIV-positive patients with pneumosepsis, matched to admissions of HIV-negative patients for age, gender and race. Matching was done by nearest neighbor matching with R package "MatchIt". RESULTS: We analyzed 2251 sepsis admissions including 41 (1.8 %) with HIV infection (32 unique patients). HIV-positive patients were younger and admission of HIV-positive patients more frequently involved pneumonia (73.2 % versus 48.8 % of admissions of HIV-negative patients, P = 0.004). Disease severity and mortality up to one year after admission did not differ according to HIV status. Furthermore, sequential plasma levels of host response biomarkers, providing insight into activation of the cytokine network, the vascular endothelium and the coagulation system, were largely similar in matched admissions of HIV-positive and HIV negative patients with pneumosepsis. CONCLUSIONS: Sepsis is more often caused by pneumonia in HIV-positive patients. HIV infection has little impact on the disease severity, mortality and host response during sepsis. PMID- 27719677 TI - Community health workers' knowledge and practice in relation to pre-eclampsia in Ogun State, Nigeria: an essential bridge to maternal survival. AB - BACKGROUND: Pre-eclampsia is a leading cause of maternal and fetal morbidity and mortality worldwide. Early detection and treatment have been instrumental in reducing case fatality in high-income countries. To achieve this in a low-income country, like Nigeria, community health workers who man primary health centres must have adequate knowledge and skills to identify and provide emergency care for women with pre-eclampsia. This study aimed to determine community health workers' knowledge and practice in the identification and treatment of pre eclampsia, as they are essential providers of maternal care services in Nigeria. METHODS: This study was part of a multi-country evaluation of community treatment of pre-eclampsia. Qualitative data were obtained from four Local Government Areas of Ogun State, in south western Nigeria by focus group discussions (N = 15) and in-depth interviews (N = 19). Participants included a variety of community-based health care providers - traditional birth attendants, community health extension workers, nurses and midwives, chief nursing officers, medical officers - and health administrators. Data were transcribed and validated with field notes and analysed with NVivo 10.0. RESULTS: Community-based health care providers proved to be aware that pre-eclampsia was due to the development of hypertension and proteinuria in pregnant women. They had a good understanding of the features of the condition and were capable of identifying women at risk, initiating care, and referring women with this condition. However, some were not comfortable managing the condition because of the limitation in their 'Standing Order'; these guidelines do not explicitly authorize community health extension workers to treat pre-eclampsia in the community. CONCLUSION: Community-based health care providers were capable of identifying and initiating appropriate care for women with pre-eclampsia. These competencies combined with training and equipment availability could improve maternal health in the rural areas. There is a need for regular training and retraining to enable successful task-sharing with these cadres. TRIAL REGISTRATION: NCT01911494 . PMID- 27719678 TI - Community health worker knowledge and management of pre-eclampsia in rural Karnataka State, India. AB - BACKGROUND: In India, the hypertensive disorders of pregnancy and postpartum haemorrhage are responsible for nearly 40 % of all maternal deaths. Most of these deaths occur in primary health settings which frequently lack essential equipment and medication, are understaffed, and have limited or no access to specialist care. Community health care workers are regarded as essential providers of basic maternity care; and the quality of care they provide is dependent on the level of knowledge and skills they possess. However, there is limited research regarding their ability to manage pregnancy complications. This study aims to describe the current state of knowledge regarding pre-eclampsia and eclampsia among community health care workers (auxiliary nurse midwives, accredited social health activists, staff nurses) in northern Karnataka, India. Furthermore, this study describes the treatment approaches used by various cadres of community health workers for these conditions. The findings of this study can help plan focussed training sessions to build upon their strengths and to address the identified gaps. METHODS: Data were collected as part of a larger study aimed at assessing the feasibility of community-based treatment for pre-eclampsia. Eight focus group discussions were conducted in 2012-2013 in northern Karnataka State: four with staff nurses and auxiliary nurse midwives and four with accredited social health activists. In addition, twelve auxiliary nurse midwives and staff nurses completed questionnaires to explore their competence and self-efficacy in managing pre-eclampsia. Qualitative data were audio-recorded, transcribed verbatim and translated for thematic analysis using NVivo 10. RESULTS: Community health workers described their understanding of the origins of hypertension and seizures in pregnancy. Psychological explanations of hypertension were most commonly reported: stress, tension, and fear. The most common explanation for eclampsia was not receiving a tetanus vaccination. Despite some common misperceptions regarding aetiology, these community health workers demonstrated a good grasp of the potential consequences of hypertension in pregnancy. According to auxiliary nurse midwives and staff nurses, if hypertension was detected they encouraged rest, decreased salt intake, iron supplementation and tetanus vaccination. In addition, some staff nurses administered antihypertensives, MgSO4, or other anticonvulsants. All auxiliary nurse midwives had some awareness of MgSO4, but none had administered it themselves. CONCLUSIONS: This study showed that knowledge regarding the aetiology of pre-eclampsia was limited. Nevertheless, their basic knowledge and skills could be strengthened to more effectively manage the hypertensive disorders of pregnancy in their communities. TRIAL REGISTRATION: NCT01911494. PMID- 27719679 TI - Community perspectives on the determinants of maternal health in rural southern Mozambique: a qualitative study. AB - BACKGROUND: Mozambique has one of the highest rates of maternal mortality in sub Saharan Africa. The main influences on maternal health encompass social, economic, political, environmental and cultural determinants of health. To effectively address maternal mortality in the post-2015 agenda, interventions need to consider the determinants of health so that their delivery is not limited to the health sector. The objective of this exploratory qualitative study was to identify key community groups' perspectives on the perceived determinants of maternal health in rural areas of southern Mozambique. METHODS: Eleven focus group discussions were conducted with women of reproductive age, pregnant women, matrons, male partners, community leaders and health workers. Participants were recruited using sampling techniques of convenience and snow balling. Focus groups had an average of nine participants each. The heads of 12 administrative posts were also interviewed to understand the local context. Data were coded and analysed thematically using NVivo software. RESULTS: A broad range of political, economic, socio-cultural and environmental determinants of maternal health were identified by community representatives. It was perceived that the civil war has resulted in local unemployment and poverty that had a number of downstream effects including lack of funds for accessing medical care and transport, and influence on socio-cultural determinants, particularly gender relations that disadvantaged women. Socio-cultural determinants included intimate partner violence toward women, and strained relationships with in-laws and co-spouses. Social relationships were complex as there were both negative and positive impacts on maternal health. Environmental determinants included natural disasters and poor access to roads and transport exacerbated by the wet season and subsequent flooding. CONCLUSIONS: In rural southern Mozambique, community perceptions of the determinants of maternal health included political, economic, socio-cultural and environmental factors. These determinants were closely linked with one another and highlight the importance of including the local history, context, culture and geography in the design of maternal health programs.

The article describes the RRT techniques in detail with the relevant technology, procedures, and phases of treatment and key aspects of volume management/fluid balance in critically ill patients. In addition, the article describes recent developments in other extracorporeal therapies, including therapeutic plasma exchange, multiple organ support therapy, liver support, lung support, and blood purification in sepsis. This is a consensus report on nomenclature harmonization in extracorporeal blood purification therapies, such as hemofiltration, plasma exchange, multiple organ support therapies, and blood purification in sepsis. PMID- 27719681 TI - Human resource constraints and the prospect of task-sharing among community health workers for the detection of early signs of pre-eclampsia in Ogun State, Nigeria. AB - BACKGROUND: The dearth of health personnel in low income countries has attracted global attention. Ways as to how health care services can be delivered in a more efficient and effective way using available health personnel are being explored. Task-sharing expands the responsibilities of low-cadre health workers and allows them to share these responsibilities with highly qualified health care providers in an effort to best utilize available human resources. This is appropriate in a country like Nigeria where there is a shortage of qualified health professionals and a huge burden of maternal mortality resulting from obstetric complications like pre-eclampsia. This study examines the prospect for task-sharing among Community Health Extension Workers (CHEW) for the detection of early signs of pre eclampsia, in Ogun State, Nigeria. METHODS: This study is part of a larger community-based trial evaluating the acceptability of community treatment for severe pre-eclampsia in Ogun State, Nigeria. Data was collected between 2011 and 2012 using focus group discussions; seven with CHEWs (n = 71), three with male decision-makers (n = 35), six with community leaders (n = 68), and one with member of the Society of Obstetricians and Gynaecologists of Nigeria (n = 9). In addition, interviews were conducted with the heads of the local government administration (n = 4), directors of planning (n = 4), medical officers (n = 4), and Chief Nursing Officers (n = 4). Qualitative data were analysed using NVivo version 10.0 3 computer software. RESULTS: The non-availability of health personnel is a major challenge, and has resulted in a high proportion of facility based care performed by CHEWs. As a result, CHEWs often take on roles that are designated for senior health workers. This role expansion has exposed CHEWs to the basics of obstetric care, and has resulted in informal task-sharing among the health workers. The knowledge and ability of CHEWs to perform basic clinical assessments, such as measure blood pressure is not in doubt. Nevertheless, there were divergent views by senior and junior cadres of health practitioners about CHEWs' abilities in providing obstetric care. Similarly, there were concerns by various stakeholders, particularly the CHEWs themselves, on the regulatory restrictions placed on them by the Standing Order. CONCLUSION: Generally, the extent to which obstetric tasks could be shifted to community health workers will be determined by the training provided and the extent to which the observed barriers are addressed. TRIAL REGISTRATION: NCT01911494. PMID- 27719680 TI - Potential for task-sharing to Lady Health Workers for identification and emergency management of pre-eclampsia at community level in Pakistan. AB - BACKGROUND: An estimated 276 Pakistani women die for every 100,000 live births; with eclampsia accounting for about 10 % of these deaths. Community health workers contribute to the existing health system in Pakistan under the banner of the Lady Health Worker (LHW) Programme and are responsible to provide a comprehensive package of antenatal services. However, there is a need to increase focus on early identification and prompt diagnosis of pre-eclampsia in community settings, since women with mild pre-eclampsia often present without symptoms. This study aims to explore the potential for task-sharing to LHWs for the community-level management of pre-eclampsia and eclampsia in Pakistan. METHODS: A qualitative exploratory study was undertaken February-July 2012 in two districts, Hyderabad and Matiari, in the southern province of Sindh, Pakistan. Altogether 33 focus group discussions (FGDs) were conducted and the LHW curriculum and training materials were also reviewed. The data was audio-recorded, then transcribed verbatim for thematic analysis using QSR NVivo-version10. RESULTS: Findings from the review of the LHW curriculum and training program describe that in the existing community delivery system, LHWs are responsible for identification of pregnant women, screening women for danger signs and referrals for antenatal care. They are the first point of contact for women in pregnancy and provide nutritional counselling along with distribution of iron and folic acid supplements. Findings from FGDs suggest that LHWs do not carry a blood pressure device or antihypertensive medications; they refer to the nearest public facility in the event of a pregnancy complication. Currently, they provide tetanus toxoid in pregnancy. The health advice provided by lady health workers is highly valued and accepted by pregnant women and their families. Many Supervisors of LHWs recognized the need for increased training regarding pre-eclampsia and eclampsia, with a focus on identifying women at high risk. The entire budget of the existing lady health worker Programme is provided by the Government of Pakistan, indicating a strong support by policy makers and the government for the tasks undertaken by these providers. CONCLUSION: There is a potential for training and task-sharing to LHWs for providing comprehensive antenatal care; specifically for the identification and management of pre-eclampsia in Pakistan. However, the implementation needs to be combined with appropriate training, equipment availability and supervision. TRIAL REGISTRATION: ClinicalTrial.gov, NCT01911494. PMID- 27719683 TI - Community health worker knowledge and management of pre-eclampsia in southern Mozambique. AB - BACKGROUND: Mozambique has drastically improved an array of health indicators in recent years, including maternal mortality rates which decreased 63 % from 1990 2013 but the rates still high. Pre-eclampsia and eclampsia constitute the third major cause of maternal death in the country. Women in rural areas, with limited access to health facilities are at greatest risk. This study aimed to assess the current state of knowledge and the regular practices regarding pre-eclampsia and eclampsia by community health workers in southern Mozambique. METHODS: This mixed methods study was conducted from 2013 to 2014, in Maputo and Gaza Provinces, southern Mozambique. Self-administered questionnaires, in-depth interviews and focus group discussions were conducted with CHWs, district medical officers, community health workers' supervisors, Gynaecologists-Obstetricians and matrons. Quantitative data were entered into a database written in REDCap and subsequently analyzed using Stata 13. Qualitative data was imported into NVivo10 for thematic analysis. RESULTS: Ninety-three percent of CHW had some awareness of pregnancy complications. Forty-one percent were able to describe the signs and symptoms of hypertension. In cases of eclampsia, CHWs reported to immediately refer the women. The vast majority of the CHWs surveyed reported that they could neither measure blood pressure nor proteinuria (90 %). Fewer reported confidence in providing oral antihypertensives (14 %) or injections in pregnancy (5 %). The other community health care providers are matrons. They do not formally offer health services, but assists pregnant women in case of an emergency. Regarding pre-eclampsia and eclampsia, matrons were unable to recognise these biomedical terms. CONCLUSIONS: Although CHWs are aware of pregnancy complications, they hold limited knowledge specific to pre-eclampsia and eclampsia. There is a need to promote studies to evaluate the impact of enhancing their training to include additional content related to the identification and management of pre-eclampsia and eclampsia. PMID- 27719682 TI - Nomenclature for renal replacement therapy in acute kidney injury: basic principles. AB - This article reports the conclusions of a consensus expert conference on the basic principles and nomenclature of renal replacement therapy (RRT) currently utilized to manage acute kidney injury (AKI). This multidisciplinary consensus conference discusses common definitions, components, techniques, and operations of the machines and platforms used to deliver extracorporeal therapies, utilizing a "machine-centric" rather than a "patient-centric" approach. We provide a detailed description of the performance characteristics of membranes, filters, transmembrane transport of solutes and fluid, flows, and methods of measurement of delivered treatment, focusing on continuous renal replacement therapies (CRRT) which are utilized in the management of critically ill patients with AKI. This is a consensus report on nomenclature harmonization for principles of extracorporeal renal replacement therapies. Devices and operations are classified and defined in detail to serve as guidelines for future use of terminology in papers and research. PMID- 27719684 TI - Morphological and molecular identification of cryptic species in the Sergentomyia bailyi (Sinton, 1931) complex in Sri Lanka. AB - The correct identification of sand fly vectors of leishmaniasis is important for controlling the disease. Genetic, particularly DNA sequence data, has lately become an important adjunct to the use of morphological criteria for this purpose. A recent DNA sequencing study revealed the presence of two cryptic species in the Sergentomyia bailyi species complex in India. The present study was undertaken to ascertain the presence of cryptic species in the Se. bailyi complex in Sri Lanka using morphological characteristics and DNA sequences from cytochrome c oxidase subunits. Sand flies were collected from leishmaniasis endemic and non-endemic dry zone districts of Sri Lanka. A total of 175 Se. bailyi specimens were initially screened for morphological variations and the identified samples formed two groups, tentatively termed as Se. bailyi species A and B, based on the relative length of the sensilla chaeticum and antennal flagellomere. DNA sequences from the mitochondrial cytochrome c oxidase subunit I (COI) and subunit II (COII) genes of morphologically identified Se. bailyi species A and B were subsequently analyzed. The two species showed differences in the COI and COII gene sequences and were placed in two separate clades by phylogenetic analysis. An allele specific polymerase chain reaction assay based on sequence variation in the COI gene accurately differentiated species A and B. The study therefore describes the first morphological and genetic evidence for the presence of two cryptic species within the Se. bailyi complex in Sri Lanka and a DNA-based laboratory technique for differentiating them.

PMID- 27719687 TI - The Identification of Hereditary and Environmental Determinants of Frailty in a Cohort of UK Twins. AB - Our study examines the contribution of genetic and environmental factors (both shared and unique) to frailty, measured using the Rockwood Frailty Index (FI) in a sample of twins from the St Thomas' UK Adult Twin Registry. The FI was based on 39 items of potential health deficit. Study participants were 3,375 volunteer adult twins (840 monozygotic and 802 dizygotic twin-pairs) 40.0-84.5 years old. First, we used structural equation modeling to estimate the relative contribution of genetics and of the shared and unique environment to variance in FI adjusted for age. In a second analysis, multiple linear regression was used to examine variance in FI as a function of father's occupational class (a component of shared environment and a measure of childhood socioeconomic status [SES]), adjusting for age, birth weight, marital status, and health behaviors (smoking, alcohol consumption, and physical activity). Statistical analyses were conducted using IBM SPSS(r) Version 22 software and Mx open source software. Findings showed that 45% (95% confidence intervals [CIs] 30-53%) of the inter-individual variation in FI was heritable and 52% (95% CIs 47-57%) was due to the individual's unique environment. Multiple linear regression also showed a small but statistically significant inverse association between father's occupational class and FI, mediated by one's own educational attainment and birth weight. Our results indicate that frailty is both genetically and environmentally determined. Thus, its prevention and management call for a multifaceted approach that includes addressing deleterious environmental factors, some of which, like childhood SES, may act across the life course.

AB - INTRODUCTION: The onset of Alzheimer's disease (AD) affects couples' relationship. We investigated the perception of change and sexual satisfaction in spouse-caregivers and their partners diagnosed with AD. METHODS: We compared 74 dyads of people with Alzheimer's disease (PwAD)/spouse-caregivers and 21 elderly dyads control. We assessed sexual satisfaction with Questionnaire on Sexual Experience and Satisfaction (QSES), cognition using a Mini-Mental State Examination (MMSE), disease severity using a Clinical Dementia Rating scale (CDR), awareness of disease with Assessment Scale of Psychosocial Impact of the Diagnosis of Dementia (ASPIDD), functionality with Pfeffer Functional Activities Questionnaire (FAQ), depressive symptoms with Cornell Scale for Depression in Dementia (CSDD), quality of life using a Quality of Life in Alzheimer's Disease Scale (QoL-AD), and burden using a Zarit Burden Interview (ZBI). RESULTS: We found differences between the perception and no perception of change in sexual activity of PwAD (p < 0.001), spouse-caregivers (p < 0.01), and controls (p < 0.05). Moderate to severe sexual dissatisfaction was observed in 36.5% of PwAD, 65% of spouse-caregivers, and 31% of controls. PwAD sexual satisfaction was related to cognitive impairment (p < 0.05). Spouse-caregivers sexual satisfaction was related to gender (p < 0.05) and the presence of sexual activity (p < 0.001). CONCLUSIONS: The perception of change with higher sexual dissatisfaction, were significant in PwAD and their spouse-caregivers, in comparison with couples of elderly without dementia. PMID- 27719686 TI - Oral supplementation of healthy adults with 2'-O-fucosyllactose and lacto-N neotetraose is well tolerated and shifts the intestinal microbiota. AB - The gut microbiota has been established as an important player influencing many aspects of human physiology. Breast milk, the first diet for an infant, contains human milk oligosaccharides (HMO) that shape the infant's gut microbiota by selectively stimulating the growth of specific bacteria, especially bifidobacteria. In addition to their bifidogenic activity, the ability of HMO to modulate immune function and the gut barrier makes them prime candidates to restore a beneficial microbiota in dysbiotic adults and provide health benefits. We conducted a parallel, double-blind, randomised, placebo-controlled, HMO supplementation study in 100 healthy, adult volunteers, consuming chemically produced 2'-O-fucosyllactose (2'FL) and/or lacto-N-neotetraose (LNnT) at various daily doses and mixes or placebo for 2 weeks. All participants completed the study without premature discontinuation. Supplementation of 2'FL and LNnT at daily doses up to 20 g was shown to be safe and well tolerated, as assessed using the gastrointestinal symptoms rating scale. 16S rRNA sequencing analysis showed that HMO supplementation specifically modified the adult gut microbiota with the primary impact being substantial increases in relative abundance of Actinobacteria and Bifidobacterium in particular and a reduction in relative abundance of Firmicutes and Proteobacteria. This study provides the first set of data on safety, tolerance and impact of HMO on the adult gut microbiota. Collectively, the results from this study show that supplementing the diet with HMO is a valuable strategy to shape the human gut microbiota and specifically promote the growth of beneficial bifidobacteria. PMID- 27719689 TI - COST-EFFECTIVENESS OF STRUCTURED EDUCATION IN CHILDREN WITH TYPE-1 DIABETES MELLITUS. AB - OBJECTIVES: Kids in Control OF Food (KICk-OFF) is a 5-day structured education program for 11- to 16-year-olds with type 1 diabetes mellitus (T1DM) who are using multiple daily insulin injections. This study evaluates the cost effectiveness of the KICk-OFF education program compared with the usual care using data from the KICk-OFF trial. METHODS: The short-term within-trial analysis covers the 2-year postintervention period. Data on glycated hemoglobin (HbA1c), severe hypoglycemia, and diabetic ketoacidosis (DKA) were collected over a 2-year follow-up period. Sub-group analyses have been defined on the basis of baseline HbA1c being below 7.5 percent (58.5 mmol/mol) (low group), between 7.5 percent and 9.5 percent (80.3 mmol/mol) (medium group), and over 9.5 percent (high group). The long-term cost-effectiveness evaluation has been conducted by using The Sheffield Type 1 Diabetes Policy Model, which is a patient-level simulation model on T1DM. It includes long-term microvascular (retinopathy, neuropathy, and nephropathy) and macrovascular (myocardial infarction, stroke, revascularization, and angina) diabetes-related complications and acute adverse events (severe hypoglycemia and DKA). RESULTS: The most favorable within-trial scenario for the KICk-OFF arm led to an incremental cost-effectiveness ratio (ICER) of L23,688 (base year 2009) with a cost-effectiveness probability of 41.3 percent. Simulating the long-term complications using the full cohort data, the mean ICER for the base case was L28,813 (base year 2011) and the probability of the KICk OFF intervention being cost-effective at L20,000/QALY threshold was 42.6 percent, with considerable variation due to treatment effect duration. For the high HbA1c sub-group, the KICk-OFF arm was "dominant" (meaning it provided better health gains at lower costs than usual care) over the usual care arm in each scenario considered. CONCLUSIONS: For the whole study population, the cost-effectiveness of KICk-OFF depends on the assumption for treatment effect duration. For the high baseline HbA1c sub-group, KICk-OFF arm was estimated to be dominant over the usual care arm regardless of the assumption on the treatment effect duration. PMID- 27719690 TI - Impaired health status and increased incidence of diseases in Toxoplasma seropositive subjects - an explorative cross-sectional study. AB - The global seroprevalence of latent toxoplasmosis is estimated to be higher than 30%. The presence of slowly dividing parasites in tissue cysts located mainly in immunoprivileged organs was long considered asymptomatic. Recently, many studies have shown that latent Toxoplasma infections could have serious impacts on human health. Here we ran a cross-sectional study in a population of 1486 volunteers. The results showed that 333 infected subjects scored worse than 1153 controls in 28 of 29 health-related variables. Similarly, they reported higher rates of 77 of a list of 134 disorders reported by at least 10 participants of the study. Toxoplasmosis was associated most strongly with musculoskeletal (tau = 0.107, P < 0.0005), followed by neurological (tau = 0.088, P < 0.0005), immune (tau = 0.085, p < 0.0005), metabolic (tau = 0.079, P < 0.0005), respiratory (tau = 0.068, P = 0.0001), allergic (tau = 0.053, P = 0.004), digestive system (tau = 0.052, P = 0.004) and mental health disorders (tau = 0.050, P = 0.008). Results of the present cohort study, along with the previous data from many case-control studies or ecological studies suggest that latent toxoplasmosis represents a large and so far underrated public health problem.

AB - : Aim The aim of the present study was to determine general paediatrician knowledge, practices, and attitudes towards electrocardiogram (ECG) screening in school athletes during pre-participation screening exam (PPSE). METHODS: Paediatricians affiliated with a tertiary children's hospital completed a survey about ECGs for PPSE. RESULTS: In total, 205/498 (41%) responded; 92% of the paediatricians did not include an ECG as part of PPSE; 56% were aware of a case in which a student athlete in their own community had died of sudden unexplained death; 4% had an athlete in their practice die. Only 16% of paediatricians perform all 12 American Heart Association recommended elements of the PPSE. If any of these screening elements are abnormal, 69% obtain an ECG, 36% an echocardiogram, and 30% restrict patients from sports activity; 73% of them refer the patient to a cardiologist. CONCLUSION: Most of the general paediatricians surveyed did not currently perform ECGs for PPSE. In addition, there was a low rate of adherence to performing the 12 screening elements recommended by the American Heart Association. They have trouble obtaining timely, accurate ECG interpretations, worry about potential unnecessary exercise restrictions, and cost-effectiveness. The practical hurdles to ECG implementation emphasise the need for a fresh look at PPSE, and not just ECG screening. Improvements in ECG performance/interpretation would be necessary for ECGs to be a useful part of PPSE. PMID- 27719693 TI - The most brutal of human skulls: measuring and knowing the first Neanderthal. AB - A fossilized skeleton discovered in 1856 presented naturalists with a unique challenge. The strange, human-looking bones of the first recognized Neanderthal confronted naturalists with a new type of object for which they had no readily available interpretive framework. This paper explores the techniques and approaches used to understand these bones in the years immediately following the discovery, in particular 1856-1864. Historians have previously suggested that interpretations and debates about Neanderthals hinged primarily on social, political and cultural ideologies. In this paper, I will argue that much of the scientific controversy surrounding the first recognized Neanderthal centred on questions of methodology and practice, and will demonstrate this through an exploration of the tools and approaches naturalists utilized in their examinations of the fossils. This will contribute to a growing historical recognition of the complex exchange between disciplines including geology, archaeology and comparative anatomy in the early study of fossil hominins, and provide a future framework for histories of Neanderthal debates in the twentieth century. PMID- 27719694 TI - The beginnings of human palaeontology: prehistory, craniometry and the 'fossil human races'. AB - Since the nineteenth century, hominid palaeontology has offered critical information about prehistoric humans and evidence for human evolution. Human fossils discovered at a time when there was growing agreement that humans existed during the Ice Age became especially significant but also controversial. This paper argues that the techniques used to study human fossils from the 1850s to the 1870s and the way that these specimens were interpreted owed much to the anthropological examination of Stone, Bronze, and Iron Age skeletons retrieved by archaeologists from prehistoric tombs throughout Europe. What emerged was the idea that a succession of distinct human races, which were identified using techniques such as craniometry, had occupied and migrated into Europe beginning in the Ice Age and continuing into the historic period. This marks a phase in the history of human palaeontology that gradually gave way to a science of palaeoanthropology that viewed hominid fossils more from the perspective of evolutionary theory and hominid phylogeny. PMID- 27719695 TI - A translation of the Linnaean dissertation The Invisible World. AB - This study presents the first translation from Latin to English of the Linnaean dissertation Mundus invisibilis or The Invisible World, submitted by Johannes Roos in 1769. The dissertation highlights Linnaeus's conviction that infectious diseases could be transmitted by living organisms, too small to be seen. Biographies of Linnaeus often fail to mention that Linnaeus was correct in ascribing the cause of diseases such as measles, smallpox and syphilis to living organisms. The dissertation itself reviews the work of many microscopists, especially on zoophytes and insects, marvelling at the many unexpected discoveries. It then discusses and quotes at length the observations of Munchhausen suggesting that spores from fungi causing plant diseases germinate to produce animalcules, an observation that Linnaeus claimed to have confirmed. The dissertation then draws parallels between these findings and the contagiousness of many human diseases, and urges further studies of this 'invisible world' since, as Roos avers, microscopic organisms may cause more destruction than occurs in all wars. PMID- 27719696 TI - Stories of stones and bones: disciplinarity, narrative and practice in British popular prehistory, 1911-1935. AB - This paper explores how three central figures in the field of British prehistory Sir Arthur Keith, Sir Grafton Elliot Smith and Louis Leakey - deployed different disciplinary practices and narrative devices in the popular accounts of human bio cultural evolution that they produced during the early decades of the twentieth century. It shows how they used a variety of strategies, ranging from virtual witness through personal testimony to tactile demonstration, to ground their authority to interpret the increasingly wide range of fossil material available and to answer the bewildering variety of questions that could be asked about them. It investigates the way in which they positioned their own professional expertise in relation to fossil interpretation, particularly with regard to the - sometimes controversial - use they made of concepts, evidence and practices drawn from other disciplines. In doing so, they made claims that went beyond their original disciplinary boundaries. The paper argues that while none of these writers were able, ultimately, to support the wider claims they made regarding human prehistory, the nature of these claims deserves much closer attention, particularly with respect to the public role that historians of science can and should play in relation to present-day calls for greater interdisciplinarity. PMID- 27719697 TI - Introduction. PMID- 27719698 TI - Spain's magic mountain: narrating prehistory at Atapuerca. AB - The Sierra de Atapuerca in northern Spain is ranked among the most important excavation sites in human origins research worldwide. The project boasts not only spectacular hominid fossils, among them the 'oldest European', but also a fully fledged 'popularization industry'. This article interprets this multimedia industry as a generator of different narratives about the researchers as well as about the prehistoric hominids of Atapuerca. It focuses on the popular works of the three co-directors of the project. Juan Luis Arsuaga, Jose Maria Bermudez de Castro and Eudald Carbonell make deliberate use of a variety of narrative devices, resonant cultural references and strategies of scientific self commodification. All three, in different ways, use the history of science and of their own research project to mark their place in the field of human origins research, drawing on mythical elements to tell the story of the rise of a humble Spanish team overcoming all odds to achieve universal acclaim. Furthermore, the co-directors make skilful use of palaeofiction - that of Bjorn Kurten and Jean Auel, as well as writing their own - in order to tell gripping stories about compassion and solidarity in human prehistory. This mixture of nationalist and universalist narratives invites the Spanish audience to identify not just with 'their ancestors' but also with the scientists, as objects and subjects of research become conflated through popularization.

AB - Tooth wear has complex and multi-factorial etiologies that result in the surface loss of dental hard tissues. Clinic prevention and restorative technology of tooth wear are challenge for dentists with the increasing numbers of population and the transition of disease age. From the etiology and classification of tooth wear, it is crucial to accurately assess and diagnose a patient presenting with tooth wear. Fluoride application, sealant and resin bonded restoration are beneficial to manage the mild tooth wear. For severe tooth wear, it is need to fabricate the diagnostic wax-up, and resin mock-up is also used to verify the occlusal relationship and vertical dimension increase, and then an interim restoration is also used to adapt the patient to the change of occlusion. Finally, by means of contemporary adhesive technique and min-invasive treatment, the dentist can reconstruct the shape of worn tooth, effectively restore the function of chewing and improve the appearance and pronounciation. PMID- 27719700 TI - [A ten-year clinical study of cracked teeth restored with glass ceramic crowns]. AB - Objective: To evaluate the clinic performance of high strength glass ceramic crowns for the painful cracked teeth during a 10-year observation period. Methods: Forty-two posterior teeth from 36 patients were diagnosed as having a crack, biting painful and sensitivity to cold were selected in the Department of Prosthodontic, Institute and Hospital of Stomatology, Nanjing University Medical School. The lost-wax hot pressed glass ceramic crowns were bonded on the minimally invasive prepared teeth by modern adhesive technology. Patients were interviewed and went through clinic examination after one week, one month, and every six months. Results: The effectiveness of 42 glass ceramic crowns for cracked teeth was evaluated for a mean observation time over 10-year. At the first week, 29(81%) patients were free of pain, three still had sensitivity to cold and chewing pain, three still had sensitivity to cold, one had painful to cold and hot. After one month, two patients still had chewing pain, and one tooth needed endodontic treatment after six months. In 10 years, 2(5%) all ceramic crowns were broken, the other 40 restorations kept good clinical performances with a 10-year survival rate of 95%. Conclusions: The high strength glass ceramic crowns are very effective and successful in treating the cracked teeth and then keep the good mastication function and appearance.

PMID- 27719692 TI - The animal trypanosomiases and their chemotherapy: a review. AB - Pathogenic animal trypanosomes affecting livestock have represented a major constraint to agricultural development in Africa for centuries, and their negative economic impact is increasing in South America and Asia. Chemotherapy and chemoprophylaxis represent the main means of control. However, research into new trypanocides has remained inadequate for decades, leading to a situation where the few compounds available are losing efficacy due to the emergence of drug-resistant parasites. In this review, we provide a comprehensive overview of the current options available for the treatment and prophylaxis of the animal trypanosomiases, with a special focus on the problem of resistance. The key issues surrounding the main economically important animal trypanosome species and the diseases they cause are also presented. As new investment becomes available to develop improved tools to control the animal trypanosomiases, we stress that efforts should be directed towards a better understanding of the biology of the relevant parasite species and strains, to identify new drug targets and interrogate resistance mechanisms.

AB - Objective: To establish a computer-aided surgical simulation procedure based on the natural head position(NHP) for orthognathic surgery and to access the effect for correcting facial asymmetry for skeletal Class III deformity. Methods: Thirty five patients(male: 14 and female: 21, mean age: [21.5+/-2.3] years) of skeletal Class III deformity with facial asymmetry were included and divided into virtual group (16 patients) and control group(19 patients). The computer-aided surgical simulation procedure was used in the virtual group and the intermediate and final splints were fabricated using the rapid protyping technique. The traditional model surgery based on plaster casts was used in control group, and the splints were handmade. To evaluate the symmetry, three-dimensional(3D) photos were taken for all the patients before operation and 6 months after operation using the 3dMD face imaging system. Coordinate system was built based on mirror-original alignment method on the 3D photo. Thirteen soft tissue landmarks were marked on each 3D photo. The asymmetry index(AI) of those soft tissue landmarks was calculated. Results: There was no significant difference in the AI values between the two groups before surgery. Sixth month after operation, the mean AI values in the virtual group were (0.81+/-0.50) mm for subnasale, (1.01+/-0.80) mm for labiale superius, (1.94+/-1.30) mm for crista philtri, (1.60+/-1.20) mm for pogonion and (5.68+/-2.25) mm for gonion. The mean AI values in the control group were (1.49+/-1.10) mm for subnasale, (1.79+/-1.33) mm for labiale superius, (3.52+/-2.50) mm for crista philtri, (2.79+/-2.08) mm for pogonion and (8.43+/ 3.94) mm for gonion and those indexes were significantly different between the two groups(P<0.05). There was no significant difference in the AI values of the pronasale, alare, labiale inferius and cheilion between the two groups sixth month after operation. Conclusions: The introduced procedure of the virtual design based on the estimated NHP could more effectively correct the asymmetry deformity for the skeletal Class III patients. PMID- 27719704 TI - [Cone-beam CT evaluation of alveolar ridge modification subject to immediate implant with immediate loading and delayed loading]. AB - Objective: To assess and compare the radiographic outcomes of immediate implant placement with two different loading timing. Methods: The involved cases were collected from Department of Implantology, Peking University School and Hospital of Stomatology. Patients recieved immediate implant placement during 2010 Aug to 2012 Dec. The cases admitted delayed restoration program were assigned to Group I(18 patients with 21 implants), the cases admitted immediate restoration program were assigned to Group II (16 patients with 22 implants). Cone-beam CT(CBCT) was taken on the day after surgery and 6 months later. The thickness of the alveolar and the vertical alteration of marginal bone level were measured using the computer software subject to the CBCT. Wound closure was performed by single sutures in Group I. Provisional crown was delivered on the same day of implant insertion or the day after for Group II. Comparisons between baseline data and data from 6-month follow-up in both groups were conducted using paired t test(alpha=0.05). Results: The success rates of two groups were both 100%. The thickness got alteration after 6 months. The largest alteration position was at the 6 mm apical to the implant platform in Group I, which was (-0.75+/-1.31) mm. In Group II for each platform got similar alterations as -0.3 mm. There was no significant differences. Vertical alteration in two Groups showed significant difference, with (-0.73+/-1.88) mm(Group I) and (0.39+/-1.37) mm(Group II) respectively. Conclusions: Immediate restoration of dental implants which are placed in fresh extraction sockets has more advantages than delayed restoration protocol, for it shortens the course of treatment and preserves the alveolar bone.

AB - Objective: To compare and analyze the clinical outcomes of apically repositioned flap surgery and free gingival graft on keratinized gingival augmentation. Methods: Totally 30 partially edentulous patients treated with submerged implant surgery in mandibular molar area were recruited and divided into three groups: group 1(mean age: 41 years) and group 2 (mean age: 25 years) received free gingival graft 1 month after submerged implant surgery and second stage implant surgery3 months after submerged implant surgery; group 3(mean age: 44 years) received apically repositioned flap and second stage implant surgery 3 months after submerged implant surgery. The widths of keratinized gingiva were measured respectively at the time before the apically repositioned flap surgery/free gingival graft and 1 month, 6 months after the surgery. The thickness of keratinized gingiva was measured during the operation. Results: The widths of peri-implant keratinized gingiva of group 1 and group 2 were (3.1+/-1.2) mm and (3.5+/-1.0) mm 1 month after the free gingival graft surgery, (3.0+/-1.3) mm and (3.5+/-1.0) mm 6 months after the free gingival graft surgery, respectively. The widths of peri-implant keratinized gingiva in group 1 and group 2 demonstrated no statistically significant differences(P>0.05). The widths of peri-implant keratinized gingiva of group 3 was (2.6+/-0.5) mm 1 month after the apically repositioned flap surgery, (1.9+/-0.3) mm 6 months after the apically repositioned flap surgery, respectively. The widths of peri-implant keratinized gingiva(1 month and 6 months after the apically repositioned flap surgery) in group 3 showed statistically significant differences when compared with group 1 and group 2(P=0.008, P=0.000). Conclusions: The implant area treated with free gingival graft or apically repositioned flap exhibited increased width of the keratinized gingiva. The implants treated with free gingival graft exhibited more increased width of the keratinized gingiva compared with those treated with apically repositioned flap. Age showed little impact on keratinized gingival augmentation. PMID- 27719706 TI - [Accuracy of three methods for the rapid diagnosis of oral candidiasis]. AB - Objective: To explore a simple, rapid and efficient method for the diagnosis of oral candidiasis in clinical practice. Methods: Totally 124 consecutive patients with suspected oral candidiasis were enrolled from Department of Oral Medicine, Peking University School and Hospital of Stomatology, Beijing, China. Exfoliated cells of oral mucosa and saliva or concentrated oral rinse) obtained from all participants were tested by three rapid smear methods(10% KOH smear, gram-stained smear, Congo red stained smear). The diagnostic efficacy(sensitivity, specificity, Youden's index, likelihood ratio, consistency, predictive value and area under curve(AUC) of each of the above mentioned three methods was assessed by comparing the results with the gold standard(combination of clinical diagnosis, laboratory diagnosis and expert opinion). Results: Gram-stained smear of saliva(or concentrated oral rinse) demonstrated highest sensitivity(82.3%). Test of 10%KOH smear of exfoliated cells showed highest specificity(93.5%). Congo red stained smear of saliva(or concentrated oral rinse) displayed highest diagnostic efficacy(79.0% sensitivity, 80.6% specificity, 0.60 Youden's index, 4.08 positive likelihood ratio, 0.26 negative likelihood ratio, 80% consistency, 80.3% positive predictive value, 79.4% negative predictive value and 0.80 AUC). Conclusions: Test of Congo red stained smear of saliva(or concentrated oral rinse) could be used as a point-of-care tool for the rapid diagnosis of oral candidiasis in clinical practice.

AB - Objective: To investigate the concentrations and clinical significance of secreted frizzled-related protein-1(SFRP1) insaliva and gingival crevicular fluid of patients with oral submucous fibrosis (OSF) as well as the expression of SFRP1 in patients' OSF buccal mucosa. Methods: Twenty OSF patients aged 20 to 40 years old were recruited and randomly divided into two experimental groups, of which were triamcinolone acetonide group and combined triamcinolone acetonide and salvia miltiorrhiza group, respectively. Ten healthy volunteers matchable in sex and age with the patients were recruited as control group. Concentrations of SFRP1 in saliva and gingival crevicular fluid were detected by enzyme-linked immunosorbent assay before and after a continuous treatment of 4 weeks. The visual analogue scale(VAS) pain scores and opening size were also recorded. The expression of SFRP1 in samples from OSF patients' buccal mucosa was also detected using immunohistochemical method. SPSS 16.0 was applied to analyze the results of the experiments. Results: The concentrations of SFRP1 in saliva and gingival crevicular fluid before treatment were (105.8+/-27.6) ng/L and (84.7+/-33.2) ng/L in triamcinolone acetonide group, and (86.6+/-23.2) ng/L and (97.0+/-23.2) ng/L in combining group, which were both significantly lower(P<0.01) than that in normal group([153.0+/-32.8] ng/L and [157.5+/-31.1] ng/L), respectively. The positive expression rate of SFRP1 in OSF group(10%[2/20]) was significantly lower than that of the control group(10/10)(P<0.01). After the treatment for 4 weeks, the concentrations of SFRP1 increased to (141.2+/-35.3) ng/L and (130.6+/-31.3) ng/L in triamcinolone acetonide group, and to (148.5+/-65.9) ng/L and (123.0+/ 27.4) ng/L in combining group, which were both significantly higher than those of pre-treatment, respectively(P<0.01). Conclusions: The concentrations of SFRP1 in saliva and gingival crevicular fluid of OSF patients, which positively corelated to the expression of SFRP1 in OSF patients' buccal mucosa, were significantly lower than that of normal individuals and increased significantly after treatments of local injections of triamcinolone acetonide only or combined with salvia miltiorrhiza.

AB - Objective: To translate the adult comorbidity evaluation-27(ACE-27) index authored by professor JF Piccirillo into Chinese and for the purpose of assessing the possible impact of comorbidity on survival of oral cancer patients and improving cancer staging. Methods: The translation included the following steps, obtaining permission from professor Piccirillo, translation, back translation, language modification, adjusted by the advice from the professors of oral and maxillofacial surgery. The test population included 154 patients who were admitted to Peking University of Stomatology during March 2011. Questionnaire survey was conducted on these patients. Retest of reliability, internal consistency reliability, content validity, and structure validity were performed. Results: The simplified Chinese ACE-27 index was established. The Cronbach's alpha was 0.821 in the internal consistency reliability test. The Kaiser-Meyer Olkin (KMO) value of 8 items was 0.859 in the structure validity test. Conclusions: The simplified Chinese ACE-27 index has good feasibility and reliability. It is useful to assess the comorbidity of oral cancer patients. PMID- 27719709 TI - [Effect of three kinds of modelling of mandible on the finite element analysis of implant]. AB - Objective: To investigate the effect of three types of material homogeneities(isotropy, transverse isotropy, and orthotropy) of mandible on the finite element analysis of implant. Methods: Three-dimensional model of complete mandible containing an implant was constructed and analyzed with isotropic, transversely isotropic, and orthotropic models, respectively. Results: The effective stress, tensile stress, and compressive stress of cortical bone of the orthogonal model were 1.2, 1.2, and 1.1 times larger than that of the isotropic model. The effective stress, tensile stress, and compressive stress of cancellous bone of the orthogonal model were 1.6, 2.6, and 3.3 times larger than that of the isotropic model. The effective strain, tensile strain, and compressive strain of cortical bone of the transversely isotropic model were 1.1, 1.0, and 1.1 times larger than that of the isotropic model. The effective strain, tensile strain, and compressive strain of cortical bone of the orthogonal model were 2.2, 1.8, and 1.7 times larger than that of the isotropic model. The stress and strain of cancellous bone increased when the material homogeneity changed from isotropy to transverse isotropy and to orthotropy. Moreover, in term of stress and strain distribution, the orthotropic modelling of mandible was most uniform followed by the transverse isotropy and the isotropy. Conclusions: In the finite element analysis of implant system, the orthotropic property of the mandible can not be neglected.

AB - Objective: To investigate the effects of Wnt3a protein on proliferation and osteogenic differentiation of human dental pulp stem cells(DPSC). Methods: Intact human permanent teeth extracted for orthodontic reasons were collected and used as study models. The biological effects of Wnt3a on DPSC were investigated using methyl thiazolyl tetrazolium(MTT), alkaline phosphatase(ALP) activity assay, alizarin red S staining and realtime fluorescence quantitative PCR. Osteogenic related gene expression of induced DPSC was examinedby using tests of bone sialoprotein(BSP), osteocalcin(OCN), collagen type I (COL-I) and Runt-related transcription factor 2(RUNX-2). Results: Wnt3a proteininduced an increase of cell growth and treatment of DPSC with Wnt3a induced a highest increase in cell growth at the concentration of 5 MUg/L. 5 MUg/L Wnt3a proteins combined with the osteogenic medium treatment caused up-regulated osteogenic differentiation, ALP activity and express of osteogenic-related genes of DPSC, and the ALP activity(0.47+/-0.04) was significantly stronger than the other groups(osteogenic medium: 0.39+/-0.05; 20 MUg/L: 0.34+/-0.03; 50 MUg/L: 0.27+/-0.07; 100 MUg/L: 0.20+/-0.03). Conclusions: Exogenous Wnt3a protein treatment on DPSC could affect the proliferation and osteogenic differentiation.

AB - Objective: To evaluate the efficacy of gemcitabine, asparaginase , ifosfamide, dexamethasone and etoposide (GLIDE) combination for patients with newly diagnosed advanced-stage or relapsed/refractory extranodal natural killer cell lymphoma (ENKL). Methods: Fourty-two newly diagnosed advanced-stage or relapsed/refractory ENKL were enrolled from March 2010 to March 2016. Patients were treated with GLIDE for median 3 (2-6) cycles. Complete response (CR) rate, early CR (after 2 cycles) rate were evaluated after all treatment finished. Progression free survival (PFS) and overall survival (OS) were analyzed by Kaplan-Meier method and multivariate by Cox proportional hazards models. Results: Thirty-one (73.8%) patients achieved CR with 22 (52.4%) in early CR after 2 cycles of GLIDE, and 14 underwent autologous stem cell transplantation (ASCT) after achieved CR. One year PFS and OS were 65.6% and 82.7%, 4 year PFS and OS were 48.2% and 63.1%, respectively, with a median PFS of 30.5 months. Multivariate analysis indicated ECOG score 0-1 and ASCT after CR were independent prognostic factors for less relapse and longer survival. Conclusion: GLIDE is an effective regiment for newly diagnosed advanced-stage and relapsed/refractory ENKL. PMID- 27719717 TI - [Efficacy of additional two cycles of rituximab administration for patients with diffuse large B-cell lymphoma in first remission]. AB - Objective: To analyze the efficacy of additional two cycles of rituximab administration for Chinese patients with diffuse large B-cell lymphoma (DLBCL) in first complete remission (CR) after six cycles of standard 21-day rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP21). Methods: Retrospective analysis was performed in 351 patients with DLBCL diagnosed from March 2003 to March 2012. International Prognosis Index (IPI), Revised (R)-IPI and National Comprehensive Cancer Network (NCCN)-IPI were calculated for each patient. Patients were divided into GCB and non-GCB subtype according to Han's Classification. Progression-free survival (PFS) and overall survival (OS) were analyzed using Kaplan-Meier methods. Results: 282 (80.3%) patients achieved CR and 132 (46.8%) of 282 cases received additional two rituximab therapy. The other 150 (53.2%) patients entered into observation on the intention of the patients. No significant difference was observed in baseline characteristics between the two groups. 3-year estimated PFS for additional rituximab group and observation group were 80.0% and 78.1% (P=0.334), while 3-year estimated OS were 89.7% vs. 86.1% (P=0.452). By subgroup analysis, prolonged PFS were observed in R-IPI low risk and NCCN-IPI low-risk patients after additional two rituximab cycles. Conclusion: For patients with DLBCL in first remission after standard six cycles of R-CHOP21 regimen, additional two cycles of rituximab maintenance did not significantly improve the general prognosis, but low-risk subgroups of R-IPI and NCCN-IPI could benefit from this regimen.

Results: The median age was 56 years (range 30-77 years) with a male-to-female ratio of 2?1. Nobody had underlying diseases associated with immunosuppression. Primary extra nodal diseases were observed in 7 cases and only 1 patient had oral involvement. Two patients were in earlystage and 7 in advanced stage by the Ann Arbor stage system. Ki-67 index was 60%-90% in the 9 cases, and 80% or higher in 7 cases. Epstein-Barr virus-encoded RNA expression (EBER) was detected in 4 cases, and 2 of them were positive. Chemotherapy was documented in 9 patients, from which 8 received the cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP)-like regimens as the first-line chemotherapy and responses were observed in 5 (1 complete, 4 partial responses). Three elderly patients were treated with CHOP combined with thalidomide, and 2 of them achieved partial responses. One patient, failed three chemotherapy regimens, accepted thalidomide combined with etopside and achieved stable disease for 10 months. One patient with early stage had disease-free survival of 61.9 months after treatment. The other eight patients experienced recurrence or progression after the first-line chemotherapy, and 6 of them died of disease progression within 2 years after the diagnosis. Conclusion: The HIV-negative PBL patients in this study did not have an apparent association with immunosuppression. Primary extra nodal diseases were common, but only 1 patient had oral involvement. Most patients had advanced stage and poor prognosis. Effectiveness of thalidomide in the treatment of PBL deserves further investigation.

AB - Objective: To analyze the clinical features and outcomes of Burkitt lymphoma with testicular involvement and study the efficiency of high dose methotrexate (HD MTX: 5-8g/m2) in those patients without radiation therapy. Method: Retrospective analysis was conducted in 16 Burkitt's lymphoma cases with testicular lymphoma involvement between Jan 2009 and Dec 2014. We followed the BCH-NHL-2009 protocol, modified from FAB LMB 89 combined with rituximab. All patients were enrolled in high-risk group (treated by Group C protocol). Results: Of 137 Burkitt lymphoma, 16 (11.67% ) had testicular involvement. All the patients were in stage IV, the median age was 6.65 years (ranges: 2.25 to 13.5 years). 8 cases had bone marrow involvement, 9 with central nervous system involvement, 5 with bi-testicular involvement, 1 with EB virus infection (EBV-IgM+). The median follow-up was 31.8 months (ranges: 0.5 to 79 months). During the study period, 2 cases died, 1 due to the disease relapse, the other one due to chemo-related dead. 1 had disease relapse 32 months after off treatment; the other 13 cases were all event free survival. 3-year OS was 87.5%, 3-year EFS was 72.9%. We also found the level of testosterone in ten adolescent were normal before and after chemotherapy. Conclusion: For the Burkitt lymphoma with testicular involvement, we abandon radiotherapy, and administer HD-MTX to lower the toxicity. The short-term survival is better, long-term survival still needs to be clarified. PMID- 27719720 TI - [IGHV mutational statue in patients with splenic marginal zone lymphoma]. AB - Objective: To investigate the IGHV mutational status and its differences from Caucasian in splenic marginal zone lymphoma (SMZL). Methods: A retrospective study on 40 SMZL cases were performed to detect the V-D-J sequence of IGHV by plasmid cloning sequencing, comparing the data with the most homologous germ line V sequence in database, identifying the stereotype of patients through cluster analysis and alignment. The clinical and laboratory characteristics were compared between the patients with IGHV mutation and without mutations. Results: In SMZL patients, the proportion of IGHV mutations was 75%, consistent with data from Caucasian. In V region, the usage of V3-23 subtype was lower in Chinese patients compared with Caucasian (2.6% vs 18.0%, P=0.006), whereas the V2-70 subtype was used with high proportion (10.3% vs 0.8%, P=0.002). In D region, the D2-21 and D6 13 gene were used frequently (17.9% vs 2.3%, P<0.001; 12.8% vs 3.8%, P=0.046). One new stereotype was found, and the SMZL-biased V1-2 gene was mostly used (25.6%). The levels of IgG and IgA were significantly increased in IGHV without mutations as compared with mutations [10.70 (5.28-15.50) g/L vs 12.90 (7.71 23.50) g/L, 1.06 (0.21-3.13) g/L vs 1.66 (0.81-2.93) g/L, P=0.038, 0.040]. The only two 17p deletion patients were IGHV without mutaions. The progression free survival (PFS) was significantly prolonged in IGHV mutations (P=0.009), and there was no significant difference regarding to the overall survival between the two subgroups (P=0.430). Conclusion: The proportion of IGHV mutaions was similar to the data in Caucasian. There was disparity in the usage of V and D regions between Chinese and Caucasian, and the SMZL-biased V1-2 gene were used more frequently in Chinese patients. One new stereotype was identified. In the IGHV without mutations group, the levels of IgG and IgA were significantly increased. PMID- 27719721 TI - [T-bet in peripheral T-cell lymphoma]. AB - Objective: To evaluate the expression of transcription factor T-bet (T-box expressed in T cells) and explore its effects on prognosis in peripheral T-cell lymphoma (PTCL). Methods: This study included 109 previously untreated patients diagnosed with PTCL in the pathology system at Peking Union Medical College Hospital from 2007 to 2013. Formalin-fixed, paraffin-embedded blocks and clinical information of these patients were collected. T-bet expression was examined by immunohistochemical stain, while its relationship with clinical feature and prognosis was analyzed. Results: 109 PTCL patients included 60 PTCL-not other specified (PTCL-NOS) cases and 18 NK/T-cell lymphoma. The positive rate of T-bet was 42.2% overall, 43.3% in PTCL-NOS and 44.4% in NK/T lymphoma. T-bet high expression wasn't correlated with OS in PTCL patients (P=0.586) by Kaplan-Meier analysis. Further stratification by pathological subgroup implied a correlation of T-bet high expression with better survival in NK/T lymphoma (P=0.004), but not in PTCL-NOS (P=0.309). Multivariate analysis confirmed that high ECOG score (>=2) was an independent predictor of overall survival (HR=5.907, 95%CI 2.399~14.549, P<0.001 ). Conclusion: T-bet was detected in several PTCL subgroups with diversities, which is positively correlated with overall survival in NK/T-cell lymphoma. PMID- 27719722 TI - [Anti-tumor effects of 13-cis-retinoic acid combined with interferon alpha-2b in animal model of mantle cell lymphoma]. AB - Objective: To determine the anti-tumor effects of 13-cis-retinoic acid (13cRA) combined with interferonalpha-2b (IFNalpha-2b) in mantle cell lymphoma (MCL) animal model. Methods: The animal model of MCL was established by introducing Jeko-1 cell line into severe combined immunodeficiency disease mice. The successfully tumor-developed mice were assigned to different groups treated with negative control group (solvents), 13cRA (high dose: 200mg/kg; middle dose: 100mg/kg; low dose: 50 mg/kg) alone, IFNalpha-2b alone or combination of different dose of 13cRA with IFNalpha-2b, and positive control group (bortezomib, rituximab, cyclophosphamide), respectively. Variations of tumor volume were observed regularly. The relative tumor proliferation rate and tumor inhibition rate were calculated. Immunohistochemistry stain was used to detect the Ki-67 expression and TUNEL was applied to measure the apoptosis of tumor cells. Furthermore, the levels of Cyclin D1, caspase 9 and Rb protein were measured by Western-blot method. Results: 1 The relative tumor proliferation rates (T/C%)were 30%, 37%, 32% and 33% in middle dose, high dose groups of 13cRA as well as their combination with IFN alpha-2b, respectively. 2 Comparing with the negative control, both 13cRA at different doses and its combination with IFNalpha-2b remarkably inhibited the tumor growth (P<0.05), while no statistic significance existed in different dose group of 13cRA. IFN-alpha 2b alone didn't demonstrate the tumor-inhibition effects (P>0.05). Middle dose of 13cRA and its combination with IFN-alpha-2b demonstrated relatively high tumor-inhibition effects (59.2% and 62.6% respectively), which were similar to the effects in positive control (69.4%). 3 There was no statistic difference of Ki-67 in each experimental group. 4 Comparing with negative control group, all doses of 13cRA and their combinations with IFNalpha-2b remarkably increased the apoptosis (P<0.05), similar to the positive control group (P>0.05). However, IFNalpha-2b alone didn' t promote the apoptosis of tumor tissue (P=0.098). 5 Comparing with negative control group, IFNalpha-2b combined with each dose of 13cRA significantly decreased the levels of cycling D1 and procaspase-9, while increased the level of cleaved caspase-9 (P<0.05), which were similar to the positive control group (P>0.05). Nevertheless, 13cRA alone didn't demonstrate such effects. Conclusion: In the MCL animal model, IFNalpha-2b alone showed no effects, but combined with IFNalpha-2b, 13cRA displayed anti-tumor effects at different doses. The anti tumor mechanism of 13cRA combined with IFNalpha-2b was probably down-regulation of the cyclin D1 expression, inhibition of cell proliferation and induction of apoptosis by activating caspase-9. PMID- 27719723 TI - [Efficacy and survival analysis of DICE regimen for 97 patients with relapsed or refractory Non-Hodgkin's lymphoma]. AB - Objective: To investigate the efficacy and survival of the DICE regimen (cisplatin, ifosfamide, etoposide, dexamethasone) for relapsed and refractory NHL. Methods: Clinical data of 97 relapsed and refractory NHL patients treated with DICE regimen in Peking University Cancer Hospital between Sep 1. 2008 and Dec 31. 2013 were retrospectively analyzed, and then we evaluate the efficacy and safety of DICE regimen. Results: 1 There were 64 males and 33 females with a median age of 49 years. The most common pathological type was DLBCL (73.20%). There were 35 B-NHL patients used rituximab combined with DICE. Finally, a total of 26 patients underwent autologous stem cell transplantation (auto-HSCT) after the salvage chemotherapy. 2 The overall response rate (ORR) was 47.42%, the complete response (CR) rate was 22.68%. The ORR of the relapsed/progressive group was higher than the refractory group [67.57% (25/37) vs 35.00% (21/60), chi2= 9.736, P=0.002]. 3The median follow-up of these 97 patients was 15.0 months (1.5 80.0 months). The expected median progression-free survival (PFS) and overall survival (OS) was 12.0 (95% CI 5.0-19.0) months, 26.0 (95% CI 6.0-45.9) months. 4There was no difference between the auto-HSCT group and no auto-HSCT group in the median OS [41.0 (95%CI 8.9-73.1) vs 22.0 (95%CI 8.5-35.5) months, P=0.361]. The patients who achieved CR and PR after DICE regimen had longer OS than those patients who in stable or progressive disease (56.0 vs 18.5 months, P <0.001). Patients who used DICE combined with rituximab had longer OS than patients who only used DICE regimen (51.5 vs 28.5 months, P=0.041). The multiple-factor analysis showed that the efficacy of DICE was an independent prognostic factor of OS [HR=4.24 (95%CI 2.12-8.50), P<0.001 ]. 5 The major adverse events included neutropenia (84.54% ) , thrombocytopenia (41.24% ), anemia (68.04%), and nausea/vomiting (65.98%), 14 patients (14.43%) had liver function abnormality, 1 patient had acute renal function injury during the treatment period. There was no chemotherapy-related death occurred. Conclusion: The DICE regimen is effective in refractory and relapsed NHL, and DICE is safe and well-tolerated. The high response rate of DICE regimen may correlate with good prognosis. For the B-NHL patients who used DICE combined with rituximab had longer OS than those patients who used DICE regimen only. PMID- 27719725 TI - [The establishment and application of internal quality control system for real time quantitative PCR detection of BCR-ABL (P210) transcript levels]. AB - Objective: To set internal quality control system of BCR-ABL (P210) transcript levels for real-time quantitative PCR (RQ-PCR). Methods: Using K562 cells and HL 60 cells, we prepared high- and low-level BCR-ABL internal quality control substance. The BCR-ABL (P210) transcript levels of internal quality control substance have been determined for 184 times together with clinical samples from August 2013 to October 2015. The slope rate, intercept and correlation coefficient of standard curve were calculated according to different reagent lots (lots number 20130303, 20131212, 20140411 and 20150327 are called R1,R2,R3 and R4 for short respectively), and the detection results of quality control substance were calculated according to different reagent lots and quality control substance lots (lots number 20130725, 20140611 are called Q1,Q2 for short respectively). Then the results were analyzed by Levey-Jennings quality control chart combined with Westgard multi-rules theory. Results: 1We analyzed the slope rate and intercept of standard curve. Fifty-three times of the R1 reagent detection, 80 times of the R3 reagent detection and 14 times of the R4 reagent detection were all under control. For 37 times detection of R2 reagent, the slope rate was out of control for 6 times. It was lower than x-s for the 2-8 tests and upper the average for the 12-37 tests. The intercept was out of control for 9 times, upper the x+s for the 1-8 tests and lower the average for the 12-37 tests. 2 According to the detection results of quality control substance, for Q1 quality control substance, 49 tests by R1 reagent were under control, and 1 out of 23 tests by R2 reagent was out of control. For Q2 quality control substance, 14 tests by R2 reagent detection, 72 tests by R3 reagent detection and 14 tests by R4 reagent were all under control. Conclusion: The preparation of high- and low-level quality control substance using K562 and HL-60 cells was convenient and the detection results were reliable and stable. The application of quality control substance combined with slope rate and intercept in the internal quality control may contribute to quality assurance for quantitative detection of BCR-ABL (P210) transcript levels. PMID- 27719724 TI - [Effects of DNA methylation on ABO gene expression in leukemia]. AB - Objective: To investigate the impact of promoter CpG island methylation on ABO mRNA expression in leukemia. Methods: 25 cases of leukemia and 20 cases of normal control were studied, and the leukemia cell lines K562,HL-60 and Jurkat were treated with different concentrations of decitabine. PCR-SSP was used to identify ABO genotype, RQ-PCR for ABO mRNA expression and bisulfite sequencing PCR for DNA methylation status. Results: 1 The methylation of ABO promoter in acute myeloid leukemia patients (10 cases) and acute lymphoblastic leukemia patients (10 cases) were 53.85% and 18.22% respectively, which were obviously higher than those in control (20 cases, 2.33%) and chronic myeloid leukemia patients (5 cases, 2.12% ). 2 ABO genotype of K562 was O1O1, which has changed little before and after decitabine treatment. ABO genotype of HL-60 and Jurkat could not been identify before treatment, but showed as O1A1 and A1O2 after treatment. 3ABO mRNA expression of K562 was 1 275.67 +/- 35.86, which was obviously higher than that in HL-60 (0.54 +/- 0.07, P<0.05) and Jurkat (0.82+/-0.16, P<0.05). 4The methylation of ABO promoter in K562, HL-60 and Jurkat were 0, 58.14%, and 96.74%. As concentration of decitabine increased, the methylation of ABO promoter were decreased and the expressions of ABO mRNA were increased in HL-60 and Jurkat, which had significant differences compared with that before treatment (P<0.05). Conclusion: The methylation of ABO promoter shows a negative correlation with ABO mRNA expression. DNA methylation was an important aspect of ABO antigens decrease in acute leukemia.

PMID- 27719726 TI - [The clinical feature and outcomes of severe aplastic anemia patients suffered from bacteremia following antithymocyte globulin]. AB - Objective: To assess the clinical feature and outcomes of severe aplastic anemia (SAA) patients suffered from bacteremia following antithymocyte globulin (ATG). Methods: A total of 264 cases hospitalized in our hospital between Jan 2000 and July 2011 were enrolled into this study. We evaluated the associated pathogens of bacteremia, analyzed the risk factors by Logistic regression and estimated the overall survival (OS) by Kaplan-Meier method for the cohort of patients. Results: Bloodstream infections occurred in 49 patients, with a median age of 20 (4-62) years, including 38 cases with very SAA (VSAA) and 11 SAA patients. The median time of bacteremia was 13 (2-233) days following ATG administration. The most common microbiologically were Enterobacteriaceae (28.4% ), Pseudomonas aeruginosa (20.9% ) and Klebsiella pneumonia (14.9% ). Almost half (46.9% ) of these bacteria were resistant to most or all available antibacterial classes. Univariate and multivariate analyses demonstrated that VSAA, infections during previous week before ATG treatment were risk factors for bacteremia. The 3 and 6 months response rates (10.6% and 17.0% ) were poor in the patients with bloodstream infections, which were significantly lower than those patients without infections (35.6% and 55.6%, respectively, both P<0.001). The estimated 5 year OS were 36.4% (95%CI 21.3% to 51.5%) and 74.5% (95%CI 68.4% to 80.7%) in the two groups, respectively (P<0.001). Conclusions: 1VSAA has higher risk of bacteremia than SAA; 2Infections during previous week before ATG administration was a risk factor for bacteremia; 3 The outcomes of SAA or VSAA patients suffered from bacteremia following ATG was poor.

AB - Issue addressed The fly-in, fly-out (FIFO) work style has been linked to mental health and interpersonal issues and a need for strategies that maintain a healthy workforce. This study investigated whether 24/7 on-site chaplains deliver a service that promotes the health and well being of FIFO personnel. Methods A phenomenological approach was used to explore the perceptions of FIFO personnel working in different roles and organisational sections on a remote mine site in Western Australia. Multi-pronged strategies recruited 29 participants who represented management, supervisors, workers and support staff. Participants took part in semistructured interviews conducted either one-on-one or in pairs. Results Chaplains were described as making a valuable contribution to the physical and mental health of FIFO personnel. Specific aspects of the service such as active outreach, effective trust building and the on-site availability were identified as central to the service being accessed and overcoming barriers embedded in mining culture and masculinity. Conclusions On-site chaplaincy appears to be effective in promoting the physical and mental health of FIFO personnel working at a remote mine site. So what? This promising model of active on-site outreach offered by chaplains is set apart from existing FIFO support structures. We recommend further exploration of its potential to become part of an integrated health-support system in the mining sector and other industries. PMID- 27719734 TI - Reach, engagement, and effectiveness: a systematic review of evaluation methodologies used in health promotion via social networking sites. AB - Issue addressed Social networking sites (SNS) are increasingly popular platforms for health promotion. Advancements in SNS health promotion require quality evidence; however, interventions are often not formally evaluated. This study aims to describe evaluation practices used in SNS health promotion. Methods A systematic review was undertaken of Medline, PsycINFO, Scopus, EMBASE, CINAHL Plus, Communication and Mass Media Complete, and Cochrane Library databases. Articles published between 2006 and 2013 describing any health promotion intervention delivered using SNS were included. Results Forty-seven studies were included. There were two main evaluation approaches: closed designs (n=23), which used traditional research designs and formal recruitment procedures; and open designs (n=19), which evaluated the intervention in a real-world setting, allowing unknown SNS users to interact with the content without enrolling in research. Closed designs were unable to assess reach and engagement beyond their research sample. Open designs often relied on weaker study designs with no use of objective outcome measures and yielded low response rates. Conclusions Barriers to evaluation included low participation rates, high attrition, unknown representativeness and lack of comparison groups. Acceptability was typically assessed among those engaged with the intervention, with limited population data available to accurately assess intervention reach. Few studies were able to assess uptake of the intervention in a real-life setting while simultaneously assessing effectiveness of interventions with research rigour. So what? Through use of quasi-experimental or well designed before-after evaluations, in combination with detailed engagement metrics, it is possible to balance assessment of effectiveness and reach to evaluate SNS health promotion. PMID- 27719736 TI - Regression of vascular calcification in a parathyroidectomized patient on dialysis with untreated hypocalcemia over 12-year follow-up?. AB - Although some experimental targets involved in calcium deposition are emerging, no intervention has been described to reliably reverse vascular calcification (VC). We report a case of severe VC regression in a parathyroidectomized patient on hemodialysis over 12-year follow-up, highlighting the use of calcium-free phosphate binders and a 2.5 mEq/L calcium dialysate for reducing calcium loading, despite persistent asymptomatic hypocalcemia occurrences. This case suggests that phosphate-binder choice and calcium dialysate concentration could be influenced by other components of CKD-MBD besides biochemical parameters, such as the presence of VC, so concluding that asymptomatic hypocalcemia may not be as harmful as once supposed, and conferring greater prognostic weight to the presence of VC than to calcium levels.?. PMID- 27719735 TI - Applying systems theory to the evaluation of a whole school approach to violence prevention. AB - Issue addressed Our Watch led a complex 12-month evaluation of a whole school approach to Respectful Relationships Education (RRE) implemented in 19 schools. RRE is an emerging field aimed at preventing gender-based violence. This paper will illustrate how from an implementation science perspective, the evaluation was a critical element in the change process at both a school and policy level. Methods Using several conceptual approaches from systems science, the evaluation sought to examine how the multiple systems layers - student, teacher, school, community and government - interacted and influenced each other. A distinguishing feature of the evaluation included 'feedback loops'; that is, evaluation data was provided to participants as it became available. Evaluation tools included a combination of standardised surveys (with pre- and post-intervention data provided to schools via individualised reports), reflection tools, regular reflection interviews and summative focus groups. Results Data was shared during implementation with project staff, department staff and schools to support continuous improvement at these multiple systems levels. In complex settings, implementation can vary according to context; and the impact of evaluation processes, tools and findings differed across the schools. Interviews and focus groups conducted at the end of the project illustrated which of these methods were instrumental in motivating change and engaging stakeholders at both a school and departmental level and why. Conclusion The evaluation methods were a critical component of the pilot's approach, helping to shape implementation through data feedback loops and reflective practice for ongoing, responsive and continuous improvement. Future health promotion research on complex interventions needs to examine how the evaluation itself is influencing implementation. So what? The pilot has demonstrated that the evaluation, including feedback loops to inform project activity, were an asset to implementation. This has implications for other health promotion activities, where evaluation tools could be utilised to enhance, rather than simply measure, an intervention. The findings are relevant to a range of health promotion research activities because they demonstrate the importance of meta-evaluation techniques that seek to understand how the evaluation itself was influencing implementation and outcomes. PMID- 27719737 TI - The other side of vitamin D therapy: ?a case series of acute kidney injury due to malpractice-related vitamin D intoxication?. AB - BACKGROUND: Vitamin D deficiency is highly prevalent in Indian Kashmir. Many people get injectable vitamin D (600,000 IU/injection). At times, the dose prescribed is far above the permissible limit. We report 62 patients with malpractice-related vitamin D intoxication, presenting with hypercalcemia and acute kidney injury (AKI). METHODS: The diagnosis was made on basis of (1) history of multiple intramuscular vitamin D injections (2) toxic serum levels of 25-OH vitamin D and (3) exclusion of common causes of hypercalcemia (malignancy and hyperparathyroidism). Their presentation was either de novo AKI in 51 (group 1) or acute on top of chronic kidney disease in 11 (group 2). RESULTS: The mean age was 60 +/- 14 vs. 62 +/- 13 years, approximate number of vitamin D injections received ranged from 4 to 28 (2.4 - 16.8 million units) vs. 3 to 24 (1.8 - 14.4 million units), mean creatinine at presentation was 3.2 +/- 0.9 vs. 4.5 +/- 1.1 mg/dL, which decreased to 1.2 +/- 0.2 vs. 3.3 +/- 1.0 mg/dL, mean serum calcium on admission was 13.7 +/- 1.4 vs. 13.6 +/- 2.0 mg/dL which decreased to 10.7 +/- 1.2 vs. 11.0 +/- 1.0 mg/dL on follow-up of 7.2 +/- 0.6 months, mean vitamin D level was 313.3 +/- 54.8 (range 235 - 375) vs. 303.7 +/- 48.4 (range 210 - 375) nmol/L and mean PTH was 18.1 +/- 9.6 (range 6.2 - 32) vs. 52.3 +/- 12.6 (range 28 - 88) pg/mL in group 1 vs. group 2, respectively. The clinical presentation was weakness, constipation, abdominal pain, nausea, vomiting, anorexia, altered sensorium, and oliguria. The treatment received was intravenous fluids (normal saline) in all in group 1 and in 8/11 in group 2, short course of steroids (prednisolone) in 44, and bisphosphonate in 6. CONCLUSION: This is the largest case series of AKI secondary to vitamin D toxicity ever reported.?. PMID- 27719738 TI - Bendamustine-induced nephrogenic diabetes insipidus?. AB - A 59-year-old man presented with polyuria and polydipsia immediately following his sixth cycle of rituximab and bendamustine for chronic lymphocytic leukemia. He initially compensated by increasing his oral fluid intake at home, but later developed septic shock and was admitted with orders to be kept nil per os (NPO). This prompted an episode of acute hypernatremia during which he exhibited continued polyuria with inappropriately dilute urine. Desmopressin challenge yielded no response in the urine osmolality, indicating a nephrogenic source of his diabetes insipidus (DI). He had no known exposure to other causative agents and had demonstrated a robust response to chemotherapy. The patient became eunatremic once oral intake was resumed and his infection was treated. Two months after presentation, he remained symptomatic. A trial with hydrochlorothiazide resulted in a significant increase in urine osmolality and subsequent decrease in urine output. To our knowledge, this is the first case of nephrogenic diabetes insipidus after rituximab and bendamustine exposure. We propose that bendamustine, similar to the alkylating agent ifosfamide, is toxic to the glomerulus and proximal tubule cells and is the most likely cause of the patient's nephrogenic DI.?. PMID- 27719739 TI - Early recognition of gonadal dysgenesis in congenital nephrotic syndrome?. AB - Mutation of the Wilms tumor suppressor gene (WT1) has been recognized as one of the etiologies of steroid-resistant nephrotic syndrome (SRNS). The mutation is also responsible for gonadal dysgenesis in 46,XY individuals. Early recognition of the presence of Y chromosome is of particular importance because of the high risk of gonadal tumor. We present here three cases of steroid-resistant nephrotic syndrome with WT1 mutation and 46,XY karyotype. Patient 1 and 2 have intron splice site (IVS9+5G A) mutation. Patient 3 has c.1301GA (p. R434H) mutation. All cases had normal female external genitalia at birth and eluded the diagnosis of gonadal dysgenesis until later in life. We suggest that chromosomal analysis should be promptly performed in female patients with early-onset steroid resistant nephrotic syndrome.?. PMID- 27719740 TI - Berberine promotes antiproliferative effects of epirubicin in T24 bladder cancer cells by enhancing apoptosis and cell cycle arrest?. AB - OBJECTIVE: The present study was aimed to observe the effect of berberine (Ber) on epirubicin (EPI)-induced growth inhibition, apoptosis, and cell cycle arrest in T24 bladder cancer cells. METHODS: The cancer cells were exposed to EPI, with or without different concentrations of Ber. The viability of the cancer cells was measured by cell counting Kit-8, the apoptosis was determined by Hoechst 33258 staining and the expression of cleaved caspase-3, cleaved caspase-9, Bcl-2, Bax, and P53 proteins were detected by Western blot assay. In addition, cell cycle arrest and the production of reactive oxygen species (ROS) were also measured. RESULTS: We found that Ber enhanced the inhibitory effect of EPI on the viability of T24 cells and promoted EPI-induced cell cycle arrest at G0/G1 and apoptosis in T24 cells. EPI increased the expression of cleaved caspase-3, cleaved caspase-9, Bax, P53, and P21 proteins, all of which were enhanced by treatment with Ber. In contrast, Ber exposure further decreased the expression of Bcl-2 in EPI-treated T24 cells. Furthermore, we also demonstrated that Ber significantly increased ROS production in EPI-treated T24 cells. CONCLUSIONS: These data indicate that Ber enhances the antiproliferative effects of EPI in bladder cancer cells by promoting apoptosis and cell cycle arrest.?. PMID- 27719741 TI - Evaluation of the safety, pharmacokinetics, pharmacodynamics, and drug-drug interaction potential of a selective Lp-PLA2 inhibitor (GSK2647544) in healthy volunteers?. AB - OBJECTIVE: To evaluate in healthy volunteers the safety, pharmacokinetics (PK), pharmacodynamics (PD), and drug-drug interaction (DDI) potential of GSK2647544, (a selective lipoprotein-associated phospholipase A2 (Lp-PLA2) inhibitor). METHODS: Study 1 was a single-blind, randomized, placebo-controlled, crossover study with healthy male volunteers randomized to receive single escalating oral doses (0.5 - 750 mg) of GSK2647544. Study 2 was a single-blind, randomized, placebo-controlled study with healthy volunteers randomized to receive repeat doses (80 mg) of GSK2647544. The drug-drug interaction of GSK2647544 with simvastatin was also evaluated in study 2. RESULTS: Across both studies GSK2647544 doses were generally well tolerated with no GSK2647544-related clinically significant findings. GSK2647544 was readily absorbed and its plasma concentration declined bi-exponentially with a terminal half-life ranging from 8 to 16 hours. Plasma exposure of GSK2647544 increased approximately dose proportionally. There was GSK2647544 dose-dependent inhibition of plasma Lp-PLA2 activity, with a trough inhibition (12 hours after dose) of 85.6% after 7-day twice daily dosing. The administration of simvastatin concomitantly with GSK2647544 increased the overall exposure (area under the plasma concentration time curve and maximum plasma concentration) of simvastatin and simvastatin acid by 3.6- to 4.3-fold and 1.5- to 3.1-fold, respectively. CONCLUSIONS: GSK2647544 was generally well tolerated and had a reasonable PK-PD profile. The clinically significant drug-drug interaction led to an early termination of study 2.?. PMID- 27719742 TI - Blood lipid abnormality changes the rate of alveolar-capillary uptake of sevoflurane: a prospective, non-interventional, clinical study?. AB - OBJECTIVE: This research studied the influence of different blood lipid components on the rate of alveolar-capillary uptake of sevoflurane. Method: 104 patients aged 20 - 50 years undergoing elective operations under general anesthesia were mechanically ventilated through endotracheal intubation after intravenous injections of midazolam, vecuronium, fentanyl, and etomidate. They inhaled 2% sevoflurane at an oxygen flow of 2 L/min, then the inspired concentrations (FI) and expired concentrations (FA of sevoflurane were recorded at 1, 3, 5, 7, 10, 15, 20, and 30 minutes. These cases were divided into a normal group and an abnormal group according to the lipid levels. Then, based on the lipid criteria, those cases with abnormal lipid levels were classified into a high-triglyceride (TG) and total-cholesterol (TC) group (group TG+TC) and a group with decreased high-density lipoprotein cholesterol (group HDL-C).The values of FA/FI and the times required to reach the titration value FA/FI = 0.8 were calculated were calculated for each group. RESULTS: Compared with the normal group, FA/FI decreased within 7 - 10 minutes (p < 0.05) and the time taken to reach the titration value was prolonged in the abnormal group (p < 0.05). The value of FA/FI decreased during 7 - 10 minutes (p < 0.05) and the time taken to reach the titration value was longer (p < 0.05) in the group TG+TC. CONCLUSIONS: The increased value of blood/gas partition coefficients (B/G) was caused by the increase in the concentrations of TG and TC in blood lipids.?. PMID- 27719743 TI - Effect of food on the oral bioavailability of the angiotensin receptor - neprilysin inhibitor sacubitril/valsartan (LCZ696) in healthy subjects?. AB - OBJECTIVE: Sacubitril/valsartan (LCZ696) provides a novel therapeutic approach of neurohormonal modulation in heart failure via simultaneous inhibition of neprilysin and blockade of the angiotensin II type-1 receptor. This study was conducted to evaluate the effect of food on the oral bioavailability of LCZ696 analytes. MATERIALS AND METHODS: This was an open-label, randomized, 3-period crossover study in healthy subjects. Eligible subjects (N = 36) were randomized to 6 treatment sequences, each comprising 3 treatment periods during which subjects received a single oral dose of 400 mg LCZ696 under fasting condition and following a low- and high-fat meal. RESULTS: Following administration of LCZ696 after low- and high-fat meals, the mean Cmax of sacubitril and sacubitrilat (the active neprilysin inhibitor) decreased by 42 - 54% and 19 - 28%, respectively, while the tmax values increased. However, systemic exposure (AUCinf and AUClast) of sacubitril was slightly decreased (by 16% with low-fat meal) and that of sacubitrilat was unchanged in the presence of food. For valsartan, the Cmax decreased by ~ 40% when LCZ696 was administered after low- and high-fat meals. The systemic exposure of valsartan decreased by ~ 33% with a low-fat meal; however, it was unchanged with a high-fat meal. LCZ696 was generally safe and well tolerated in healthy subjects when administered under fasting or fed condition. CONCLUSION: Overall, administration of LCZ696 with meals decreased the rate and extent of absorption of sacubitril with little impact on the systemic exposure to sacubitrilat, its active metabolite. The systemic exposure to valsartan was decreased in the presence of food.?. PMID- 27719744 TI - Tolerability and safety of Octagam(r) (IVIG): a post-authorization safety analysis of four non-interventional phase IV trials?. AB - OBJECTIVE: To evaluate the tolerability and safety of Octagam(r) 5% and 10% across all indications, ages, and treatment regimens, using data from four non-interventional post-authorization safety studies (PASS); this analysis was performed following changes in the preparation of raw material used to manufacture Octagam. METHODS: All four studies included in- and out-patients prescribed Octagam for treatment of their medical condition. Physicians used case report forms to document baseline demographics, Octagam treatment details, and data on the efficacy of Octagam, and recorded all adverse drug reactions (ADRs) and other safety data. RESULTS: Altogether 21,780 infusions of Octagam in 2,397 patients were included in our analysis. The most frequent indication for Octagam was secondary immunodeficiencies (SID; n = 1,368, 11,348 infusions), followed by primary immunodeficiencies (PID; n = 363; 3,923 infusions). During the individual patient observation, 83% of SID and 67% of PID patients were free of any infection. In up to 85% of all investigator assessments, Octagam was rated to have a favorable effect. In autoimmune diseases, investigators assessed Octagam as being beneficial in 70% (immune thrombocytopenia) up to 100% (Guillain-Barre syndrome), depending on the indication. The majority of patients (92%) tolerated Octagam treatment without any ADR. The overall incidence of reported ADRs was 1.0% for all infusions. The majority of ADRs were considered non-serious (93%) and mild or moderate (87%) in severity. No unexpected ADR signal was detected. CONCLUSIONS: This analysis demonstrates that the changes in the preparation of raw material used to manufacture Octagam did not affect the safety profile of Octagam(r) 5% and 10%.? *At the time of study realization. PMID- 27719746 TI - Brain metastasis from gastrointestinal clear cell sarcoma. AB - Clear cell sarcoma (CCS) of the gastrointestinal tract presents a diagnostic challenge to the pathologist due to its morphological and immunohistochemical similarity to melanoma. It usually metastasizes to regional lymph nodes, liver, and lungs. Herein, we report the first known metastasis of a gastrointestinal CCS to the central nervous system. Cytogenetic testing showed the t(12,22) translocation corresponding to the presence of the EWS/ATF1 hybrid consistent with CCS. The literature that compares melanoma to CCS is reviewed in the context of this rare presentation to differentiate between the two diseases.?. PMID- 27719745 TI - Pathological background of subcortical hyperintensities on diffusion-weighted images in a case of neuronal intranuclear inclusion disease. AB - AIMS: Neuronal intranuclear inclusion disease (NIID) is a rare neurodegenerative disorder with eosinophilic intranuclear inclusion bodies. The variable symptoms of NIID increase the difficulty in an antemortem diagnosis. NIID shows leukoencephalopathy on brain magnetic resonance imaging MRI, but the significance of the radiological findings have not been clarified. METHODS: We examined an autopsied case of NIID with subcortical linear hyperintensities on diffusion weighted imaging (DWI) and leukoencephalopathy on fluid attenuation inversion recovery (FLAIR) imaging. Semiquantitative analysis was performed by merging coronal sections of DWI and identical hematoxylin-eosin (H & E) stained brain specimens. The severity of spongiotic changes, the common pathological findings of NIID, were quantified and compared with MRI lesions classified by DWI signals. RESULTS: The white matter showed diffuse myelin pallor, and multiple focal spongiotic changes were present in the subcortical white matter proximal to the U fibers. Spongiotic changes were restricted in the lesions with subcortical linear DWI high signals. CONCLUSION: Subcortical DWI high signals in NIID strongly correlate with pathological spongiotic changes of NIID. Subcortical spongiotic changes may be a characteristic finding of NIID.?. PMID- 27719747 TI - Mitochondrial proteomics reveal potential targets involved in mitochondrial abnormalities of desminopathy. AB - AIMS: To investigate the underlying mechanisms of how the defects of desmin cause mitochondrial abnormalities in desminopathy. MATERIAL AND METHODS: Primary myoblasts were isolated from muscle biopsy of a desminopathy patient with mitochondrial abnormalities. Two-dimensional gel electrophoresis analyses of mitochondrial proteins were performed in mitochondria isolated from myoblasts. Immunostaining, immunoblot, and mitochondrial function tests were carried out to confirm the proteomic results. RESULTS: 42 proteins were found with significant expression differences in the mitochondrial proteomics. Several proteins associated with regulation of the mitochondrial permeability transition pore (MPTP) complex were identified in functional cluster analysis. The patterns of protein expression were also confirmed by strong immunoreactivity, increased MPTP opening and elevated level of oxidative stress. CONCLUSIONS: The study provides an overall perspective of the mitochondrial proteome plasticity in a case of desminopathy with mitochondrial abnormalities. The expression patterns of protein associated with MPTP indicate that desmin might affect MPTP complex as potential targets involved in mitochondrial dysfunction in desminopathy. However, the precise underlying mechanism remains to be elucidated.?. PMID- 27719748 TI - Astrocytoma with extensive infiltration of Virchow-Robin spaces.

AB - A norovirus recombinant GII.P4_NewOrleans_2009/GII.4_Sydney_2012 was first detected in Victoria, Australia, in August 2015 at low frequency, and then re emerged in June 2016, having undergone genetic changes. Analysis of 14 years' surveillance data from Victoria suggests a typical delay of two to seven months between first detection of a new variant and occurrence of a subsequent epidemic linked to that variant. We consider that the current recombinant strain has the potential to become a pandemic variant. PMID- 27719751 TI - Increase in ECHOvirus 6 infections associated with neurological symptoms in the Netherlands, June to August 2016. AB - The Dutch virus-typing network VIRO-TypeNed reported an increase in ECHOvirus 6 (E-6) infections with neurological symptoms in the Netherlands between June and August 2016. Of the 31 cases detected from January through August 2016, 15 presented with neurological symptoms. Ten of 15 neurological cases were detected in the same province and the identified viruses were genetically related. This report is to alert medical and public health professionals of the circulation of E-6 associated with neurological symptoms.

PMID- 27719752 TI - VIRO-TypeNed, systematic molecular surveillance of enteroviruses in the Netherlands between 2010 and 2014. AB - VIRO-TypeNed is a collaborative molecular surveillance platform facilitated through a web-based database. Genetic data in combination with epidemiological, clinical and patient data are shared between clinical and public health laboratories, as part of the surveillance underpinning poliovirus eradication. We analysed the combination of data submitted from 2010 to 2014 to understand circulation patterns of non-polio enteroviruses (NPEV) of public health relevance. Two epidemiological patterns were observed based on VIRO-TypeNed data and classical surveillance data dating back to 1996: (i) endemic cyclic, characterised by predictable upsurges/outbreaks every two to four years, and (ii) epidemic, where rare virus types caused upsurges/outbreaks. Genetic analysis suggests continuous temporal displacement of virus lineages due to the accumulation of (silent) genetic changes. Non-synonymous changes in the antigenic B/C loop suggest antigenic diversification, which may affect population susceptibility. Infections were frequently detected at an age under three months and at an older, parenting age (25-49 years) pointing to a distinct role of immunity in the circulation patterns. Upsurges were detected in the summer and winter which can promote increased transmissibility underlying new (cyclic) upsurges and requires close monitoring. The combination of data provide a better understanding of NPEV circulation required to control and curtail upsurges and outbreaks. PMID- 27719755 TI - French Aedes albopictus are able to transmit yellow fever virus. AB - We assessed the ability of a French population of Aedes albopictus to transmit yellow fever virus (YFV). Batches of 30 to 40 female mosquitoes were analysed at 7, 14 and 21 days post-exposure (dpe). Bodies, heads and saliva were screened for YFV. Infectious viral particles were detected in bodies and heads at 7, 14 and 21 dpe whereas the virus was found in saliva only from 14 dpe. Our results showed that Ae. albopictus can potentially transmit YFV. PMID- 27719756 TI - 'European Antibiotics Awareness Day' wins 'European Health Award 2016' accolade.

PMID- 27719759 TI - Cortical flow aligns actin filaments to form a furrow. AB - Cytokinesis in eukaryotic cells is often accompanied by actomyosin cortical flow. Over 30 years ago, Borisy and White proposed that cortical flow converging upon the cell equator compresses the actomyosin network to mechanically align actin filaments. However, actin filaments also align via search-and-capture, and to what extent compression by flow or active alignment drive furrow formation remains unclear. Here, we quantify the dynamical organization of actin filaments at the onset of ring assembly in the C. elegans zygote, and provide a framework for determining emergent actomyosin material parameters by the use of active nematic gel theory. We characterize flow-alignment coupling, and verify at a quantitative level that compression by flow drives ring formation. Finally, we find that active alignment enhances but is not required for ring formation. Our work characterizes the physical mechanisms of actomyosin ring formation and highlights the role of flow as a central organizer of actomyosin network architecture. PMID- 27719762 TI - Local, Regional, and Spinal Anesthesia in Ruminants. AB - Local, regional, and spinal anesthesias are safe, effective, often more desirable procedures for ruminants than general anesthesia. Many procedures can be performed safely and humanely in ruminants using a combination of physical restraint, mild sedation, and local, regional, or spinal anesthesia. This article focuses on the use of local anesthetics for providing anesthesia for dehorning, procedures of the nose and eye, laparotomy, reproductive procedures, teat repair, and procedures on the distal limb. Local, regional, and spinal anesthesia techniques are safe effective methods for providing anesthesia for common surgical procedures and analgesia for painful conditions in cattle and small ruminants. PMID- 27719761 TI - Asymmetric effects of activating and inactivating cortical interneurons. AB - Bidirectional manipulations - activation and inactivation - are widely used to identify the functions supported by specific cortical interneuron types. Implicit in much of this work is the notion that tonic activation and inactivation will both produce valid, internally consistent insights into interneurons' computational roles. Here, using single-unit recordings in auditory cortex of awake mice, we show that this may not generally hold true. Optogenetically manipulating somatostatin-positive (Sst+) or parvalbumin-positive (Pvalb+) interneurons while recording tone-responses showed that Sst+ inactivation increased response gain, while Pvalb+ inactivation weakened tuning and decreased information transfer, implying that these neurons support delineable computational functions. But activating Sst+ and Pvalb+ interneurons revealed no such differences. We used a simple network model to understand this asymmetry, and showed how relatively small changes in key parameters, such as spontaneous activity or strength of the light manipulation, determined whether activation and inactivation would produce consistent or paradoxical conclusions regarding interneurons' computational functions. PMID- 27719763 TI - Surgery of the Sinuses and Eyes. AB - Conditions of the head requiring surgery in cattle are not uncommon when considering the incidence of conditions such as ocular squamous cell carcinoma and requests for surgical dehorning. Surgery involving the eyes in cattle is relatively common, whereas surgery of the paranasal sinuses is less common. Generally speaking, however, surgery for conditions of the head tend to have a more favorable prognosis when there is early intervention. PMID- 27719764 TI - Surgery of the Forestomach. AB - Indications for rumen surgery include rumen tympany (bloat), toxic plant ingestion, to provide enteral nutrition, to perform elective cannula placement, and to access other forestomach compartments (reticulum/omasum). The rumen is a highly contaminated viscus and special care should be taken to avoid peritoneal contamination from rumen contents. Diseases causing forestomach dysfunction and surgical procedures on the forestomach compartments are discussed here. PMID- 27719760 TI - BLOS2 negatively regulates Notch signaling during neural and hematopoietic stem and progenitor cell development. AB - Notch signaling plays a crucial role in controling the proliferation and differentiation of stem and progenitor cells during embryogenesis or organogenesis, but its regulation is incompletely understood. BLOS2, encoded by the Bloc1s2 gene, is a shared subunit of two lysosomal trafficking complexes, biogenesis of lysosome-related organelles complex-1 (BLOC-1) and BLOC-1-related complex (BORC). Bloc1s2-/- mice were embryonic lethal and exhibited defects in cortical development and hematopoiesis. Loss of BLOS2 resulted in elevated Notch signaling, which consequently increased the proliferation of neural progenitor cells and inhibited neuronal differentiation in cortices. Likewise, ablation of bloc1s2 in zebrafish or mice led to increased hematopoietic stem and progenitor cell production in the aorta-gonad-mesonephros region. BLOS2 physically interacted with Notch1 in endo-lysosomal trafficking of Notch1. Our findings suggest that BLOS2 is a novel negative player in regulating Notch signaling through lysosomal trafficking to control multiple stem and progenitor cell homeostasis in vertebrates. PMID- 27719765 TI - Urolithiasis. AB - Urolithiasis is the most common urinary problem in male ruminants, and one of the most common emergencies in male goats and sheep. This disease has substantial welfare implications because it causes severe pain and it has a high fatality rate. The expense associated with veterinary care and loss of affected animals has a strong economic impact on pet owners and farmers.

AB - Reproductive surgical techniques are considered by practitioners of theriogenology to be the best method to manage infertility-causing conditions or diseases of the bull. Injury or diseases of the reproductive tract may cause abnormalities that may result in substantial losses to the producers of beef and dairy cattle. The most cost-effective method of dealing with reproductive conditions or diseases of the bull is culling and replacement. Some injuries, diseases, or conditions are amenable to surgical management. Surgical management may preserve the genetic potential of the bull and economic productivity. The surgical procedures described are commonly used methods to restore fertility in bulls. PMID- 27719767 TI - Surgical Procedures of the Genital Organs of Cows. AB - Reproductive surgical techniques are considered by practitioners/clinicians of theriogenology to be the most beneficial reproductive management that can be performed to treat conditions of cows that may affect fertility. Conditions affecting the reproductive tract can cause pathologic changes that may result in substantial economic and genetic losses to beef and dairy producers. Some injuries and diseases are amenable to surgical treatment. Surgical restoration of fertility preserves genetic potential and economic productivity. The surgical procedures described in this article are some of the most commonly used to restore fertility in cows with injury or diseases affecting their reproductive tracts. PMID- 27719768 TI - Surgery of the Distal Limb. AB - Diseases of the bovine digit remain the major cause of painful lameness in cattle and commonly constitute a diagnostic and therapeutic challenge for clinicians. Prompt surgical wound revision is critical in acute injuries. Deep infections may be treated with debridement, resection of tendons, synovioscopy, joint lavage, arthrotomy and facilitated joint ankylosis. Postoperative care is more involved, lameness persists longer, and cost of treatment is higher after salvage techniques than after amputation of the digit. Luxations and fractures of the digits often are amenable to conservative treatment but may be treated surgically if indicated. PMID- 27719769 TI - Surgical Management of the Teat and the Udder. AB - Lacerations of the teat should be treated as emergency. First-intention repair should be attempted under sedation in lateral or dorsal recumbency. Surgeons should pay attention to the atraumatic manipulation of the tissue and the anatomic reconstruction using small-diameter absorbable suture material. Hand milking should be prohibited for 10 days postoperatively after laceration repair; prognosis is overall good. Ultrasound evaluation of the teat allows excellent understanding of the internal lesions and should be performed before planning any elective surgery. Milk outflow impairment originating from the rosette of Furstenberg or the streak canal is best treated using minimally invasive surgery (theloscopy). PMID- 27719770 TI - Ruminant Surgery.

AB - With more people having access to health care in the United States as a result of the Affordable Care Act, there is a greater need for nurses now than ever before. Generalist nurses will need to be educated, not just to care for people in hospitals, but also to promote health and help manage chronic conditions in a wide variety of health care settings. More advanced-practice nurses will be needed to provide primary care. Although the need for nurses educated at both the undergraduate and graduate levels in emerging health care systems is increasing, the number of nursing educators is decreasing. Nursing educators in the future will need to be nimble in addressing emerging health care needs while ensuring succession planning.

This article explores how Muslim women observe their religious beliefs during pregnancy and discusses implications for nursing care of pregnant Muslim women during Ramadan. Although pregnant Muslim women can be exempt from fasting, many still choose to fast during Ramadan. Factors that influence a woman's decision to fast include gravity and parity, maternal education, maternal age, body mass index, comprehension of Islamic Law, and gestational trimester. Nurses can tailor their care of pregnant Muslim women to include episodes of fasting and help them make informed decisions regarding fasting during Ramadan. PMID- 27719776 TI - Improving Breastfeeding Support by Understanding Women's Perspectives and Emotional Experiences of Breastfeeding. AB - Exclusive breastfeeding for at least 6 months is universally acknowledged as the optimal means of infant nutrition. However, current studies show that most women are not following this recommendation. Many studies address the issue of increasing breastfeeding rates, but fewer explore the perspectives and experiences of breastfeeding women. In this article we review the literature and identify common themes in women's breastfeeding experiences. Nurses and other health care providers stand to help or hinder breastfeeding women, and they must be aware of and sensitive to women's personal experiences and perspectives to understand how to best promote and support women in their attempts to meet their breastfeeding goals. PMID- 27719777 TI - A Literature Review on the Practice of Placentophagia. AB - Placentophagia (consuming the placenta) has historically not been a common practice among humans. Over the past few decades the practice has gained attention as more women, particularly educated, middle-class, White American women, choose to partake in this practice. Purported benefits of placentophagia include pain relief, increased breast milk production, and decreased risk of postpartum depression; however, there is a lack of evidence to support these claims. The placenta can be consumed raw, cooked, or encapsulated; it can be used for keepsakes; or it can be used to make topical applications such as dermatologic creams and hair-growth products. Placentophagia has typically been viewed as a personal choice, resulting in little rigorous scientific research on the topic. More research is necessary to determine if the purported health benefits of placentophagia are proven. PMID- 27719778 TI - Assessment and Care of Childbearing Women With Severe and Persistent Mental Illness. AB - Severe and persistent mental illness (SPMI) refers to complex mood disorders that include major depressive disorder with or without psychosis; severe anxiety disorders resistant to treatment; affective psychotic disorders including bipolar affective disorder, schizophrenia, and schizoaffective disorder; and other nonaffective subtypes of schizophrenia. SPMIs affect 1 in 17 people and are among the leading causes of disability and impaired health-related quality of life in the United States. Caring for childbearing women with preexisting SPMI can be challenging for maternal-child health clinicians. This article provides an overview of SPMI during pregnancy and challenges for clinicians, including early identification, accuracy of diagnoses, and appropriate management through care coordination among an interdisciplinary team that includes obstetric providers, psychiatrists, nurses, and others. PMID- 27719779 TI - von Willebrand disease in pregnancy. AB - von Willebrand disease is the most prevalent inherited bleeding disorder, affecting up to 1.3% of the population. It is caused by a defect or deficiency of the von Willebrand factor. Women with the condition may not be aware of their condition at the time of childbirth, but they are at high risk of postpartum hemorrhage even days after birth. In this article we briefly review the condition and specific considerations for the antepartum, intrapartum, and postpartum phases. It is important for nurses who care for women during childbirth to have a keen understanding of this condition. PMID- 27719781 TI - A Nonhormonal Treatment for Moderate to Severe Vasomotor Symptoms of Menopause. AB - It is estimated that up to 80% of women experience symptoms related to declining estrogen levels that occur with menopause. The most common bothersome symptoms reported by women during and after this transition are vasomotor symptoms, which can include hot flashes, flushing, night sweats, and sleep disturbances. These symptoms are the most common reason women seek care during menopause. Until recently, the mainstay of treatment and symptom relief has been estrogen supplementation. In 2013, the U.S. Food and Drug Administration approved paroxetine, a low-dose selective serotonin reuptake inhibitor, as the first nonhormonal treatment for moderate to severe vasomotor symptoms of menopause. This article provides an overview of the use of paroxetine to treat vasomotor symptoms of menopause, including potential adverse reactions, special considerations for use, and implications for nursing practice. PMID- 27719780 TI - Cue-Based Feeding in the NICU. AB - In NICU settings, caring for neonates born as early as 23 weeks gestation presents unique challenges for caregivers. Traditionally, preterm infants who are learning to orally feed take a predetermined volume of breast milk or formula at scheduled intervals, regardless of their individual ability to coordinate each feeding. Evidence suggests that this volume-driven feeding model should be replaced with a more individualized, developmentally appropriate practice. Evidence from the literature suggests that preterm infants fed via cue-based feeding reach full oral feeding status faster than their volume-feeding counterparts and have shorter lengths of stay in the hospital. Changing practice to infant-driven or cue-based feedings in the hospital setting requires staff education, documentation, and team-based communication.

While it is firstly important to understand the reasons for this refusal and what is at stake for the patient, there are a number of nursing strategies in place, not least of all dialogue and analysis. The role of the multi-disciplinary team is essential in such situations. PMID- 27719788 TI - [The refusal of nursing care by the families]. AB - Caregiving is complex. While it is not easy to admit that the process can be refused by the patient, it is no easier when it is refused by the patient's family. Accepting this fact is however an essential stage in the relational and care processes. The family must therefore be supported by professionals in order to be able to make an enlightened choice. PMID- 27719789 TI - [Remaining a caregiver in the face of a refusal of nursing care].

Sometimes contradictory to nurses' reflexes when dealing with emergencies, some basic precautions are nevertheless essential. PMID- 27719797 TI - ?

PMID- 27719828 TI - A 43-Year-Old Man With Daytime Sleepiness and a Heart Murmur. AB - A 43-year-old man was referred to our tertiary sleep center for the initiation of sleep apnea treatment. A prior diagnostic overnight polysomnography (Fig 1) had revealed an apnea-hypopnea index (AHI) of 22/h of sleep. The apneas were predominantly central (central AHI, 18.2/h; obstructive AHI, 3.8/h), more pronounced in the supine position (AHI supine, 36.6/h; AHI nonsupine, 11/h) and during non-rapid eye movement (non-REM) sleep (REM, 15.8/h; non-REM, 23.5/h). A continuous positive airway pressure (CPAP) trial in an outpatient setting had failed, as the fixed CPAP of 11 cm H2O was not tolerated by the patient because of a feeling of lightheadedness when wearing the mask. At referral, the patient complained about falling asleep in front of the computer in the afternoons despite regular bedtimes and 7 to 8 h of sleep per night. His Epworth Sleepiness Scale score was 11. He had no significant past history including cardiopulmonary disease. He was not taking any medication but had noticed a slow decline in general physical performance in the last year, with dyspnea (New York Heart Association class I) after running distances of 1 to 2 km. He had never experienced syncope. His family history was unremarkable. PMID- 27719829 TI - Deaths Related to Bronchial Arterial Embolization in Patients With Cystic Fibrosis: Three Cases and an Institutional Review. AB - Cystic fibrosis (CF) patients are at risk for life-threatening hemoptysis, sometimes necessitating bronchial arterial embolization (BAE). Spinal artery embolization and pulmonary infarction are commonly cited procedural risks, yet respiratory failure and death are underappreciated. We conducted a retrospective institutional review of our outcomes after BAE for hemoptysis in CF and present three cases highlighting this complication. From 2007 to 2015, 12 patients underwent 17 BAE procedures for hemoptysis at our institution. Three patients experienced respiratory failure and died within 3 months of BAE. Nonsurvivors had significantly lower baseline FEV1 values than survivors (21.8% vs 52.6%, P < .05). BAE as a treatment for life-threatening hemoptysis may precipitate respiratory failure in end-stage CF and should accelerate the evaluation for lung transplantation. Institutions should reevaluate their BAE practices to ensure preservation of the bronchial circulation, which contributes to gas exchange in these patients.

In non-HIV-endemic areas, where reactivation is the predominant mechanism of tuberculosis, pleural involvement occurs in 4% of cases. We present an extremely rare case of a 62-year-old immunocompetent patient with pleural tuberculosis confirmed by surgical pleural biopsies, who presented with a large mediastinal mass and evidence of pulmonary artery invasion on CT scanning and endobronchial ultrasonography imaging, highlighting a unique and malignant-like character of the disease. PMID- 27719831 TI - Psychologic theories in functional neurologic disorders. AB - In this chapter we review key psychologic theories that have been mooted as possible explanations for the etiology of functional neurologic symptoms, conversion disorder, and hysteria. We cover Freudian psychoanalysis and later object relations and attachment theories, social theories, illness behavior, classic and operant conditioning, social learning theory, self-regulation theory, cognitive-behavioral theories, and mindfulness. Dissociation and modern cognitive neuroscience theories are covered in other chapters in this series and, although of central importance, are omitted from this chapter. Our aim is an overview with the emphasis on breadth of coverage rather than depth. PMID- 27719833 TI - Voluntary or involuntary? A neurophysiologic approach to functional movement disorders. AB - Patients with functional movement disorders (FMD) experience movements as involuntary that share fundamental characteristics with voluntary actions. This apparent paradox raises questions regarding the possible sources of a subjective experience of action. In addition, it poses a yet unresolved diagnostic challenge, namely how to describe or even quantify this experience in a scientifically and clinically useful way. Here, we describe recent experimental approaches that have shed light on the phenomenology of action in FMD. We first outline the sources and content of a subjective experience of action in healthy humans and discuss how this experience may be created in the brain. Turning to FMD, we describe implicit, behavioral measures that have revealed specific abnormalities in the awareness of action in FMD. Based on these abnormalities, we propose a potential, new solution to the paradox of volition in FMD. PMID- 27719832 TI - Charcot, hysteria, and simulated disorders. AB - Jean-Martin Charcot (1825-1893) was the 19th-century's premier international neurologist. One of his areas of focused interest was the neurologic disorder, hysteria, a condition with distinctive neurologic signs, but no established structural lesions identified at autopsy. Charcot considered hysteria as a physiologic disorder that affected specific neuroanatomic areas of the brain comparable to the same areas that were damaged by structural neurologic disorders provoking the same or similar signs. He considered hysteria primarily a hereditary disorder, but environmental factors including physical and emotional stress served as provoking factors. Charcot drew the strict distinction between hysteria and consciously simulated neurologic disorders, although he was keenly aware that the two disorders could occur in the same patients or be difficult to distinguish at times. He developed specific experimental techniques to separate hysteria from simulation. His studies of hysteria and simulation offer a basis for studies of functional neurologic disorders applicable to the 21st century. PMID- 27719834 TI - Neurobiologic theories of functional neurologic disorders. AB - Although neurobiologic theories to explain functional neurologic symptoms have a long history, a relative lack of interest in the 20th century left them far behind neurobiologic understanding of other illness. Here we review the proposals for neurobiologic mechanisms of functional neurologic symptoms that have been made over time and consider how they might inform our diagnostic and treatment methods, and how they integrate with psychologic formulations of functional symptoms. Modern approaches map on to recent developments in theoretic models of brain function, and suggest a key role for processes affecting attention, beliefs/expectations, and a resultant impairment of sense of agency. PMID- 27719835 TI - Stress, childhood trauma, and cognitive functions in functional neurologic disorders. AB - Conversion disorder (CD) has traditionally been ascribed to psychologic factors such as trauma, stress, or emotional conflict. Although reference to the psychologic origin of CD has been removed from the criteria list in DSM-5, many theories still incorporate CD as originating from adverse events. This chapter provides a critical review of the literature on stressful life events in CD and discusses current cognitive and neurobiologic models linking psychologic stressors with conversion symptomatology. In addition, we propose a neurobiologic stress model integrating those cognitive models with neuroendocrine stress research and propose that stress and stress-induced changes in hypothalamus pituitary-adrenal (HPA) axis function may result in cognitive alterations, that in turn contribute to experiencing conversion symptoms. Experimental studies indeed suggest that basal as well as stress-induced changes in HPA axis responding lead to alterations in attentional processing in CD. Although those changes are stronger in traumatized patients, similar patterns have been observed in patients who do not report a history of traumatic events. We conclude that, whereas adverse events may play an important role in many cases of CD, a substantial proportion of patients do not report a history of traumatization or recent stressful events. Studies integrating effects of stress on cognitive functioning in CD are scarce. We propose that, instead of focusing research on defining etiologic events in terms of symptom-eliciting events, future research should work towards an integrated mechanistic account, assessing alterations in cognitive and biologic stress systems in an integrated manner in patients with CD. Such an account may not only serve early symptom detection, it might also provide a starting point for better-targeted interventions. PMID- 27719836 TI - Do (epi)genetics impact the brain in functional neurologic disorders? AB - Advances in neuropsychiatric research are supposed to lead to significant improvements in understanding functional neurologic disorders and their diagnosis. However, epigenetic and genetic research on conversion disorders and somatoform disorders is only at its start. This review demonstrates the current state within this field and tries to bridge a gap from what is known on gene stress interactions in other psychiatric disorders like depression. The etiology of conversion disorders is hypothesized to be multifactorial. These considerations also suggest that potential etiologic factors lead to alterations in brain function, either episodically or chronically, eventually leading to structural brain changes. In particular, the knowledge of how the environment influences brain structure and function, e.g., via epigenetic regulation, may be interesting for future research in functional neurologic disorders. Reviewing the literature results in evidence that childhood adversities play a role in the development of functional neurologic disorders, whereby at present no reports exist about the interactive effect between childhood adversity and genetic factors or about the impact of epigenetics. PMID- 27719837 TI - Assessment of patients with functional neurologic disorders. AB - We describe an overall approach and structure to the clinical assessment of the patient with a functional neurologic disorder. Whilst the primary purpose of the assessment is to make a diagnosis and develop a treatment plan, we believe the assessment also plays a key role in treatment in its own right, as it sets a tone and context for future clinical interactions. We aim to set up an atmosphere of collaboration based on taking the patient's problems seriously, and emphasizing that all facets of the patient's presentation - physical, psychologic, and social - are of importance. Patients with functional disorders can be perceived as difficult to help and yet with the correct approaches we believe the consultation can be much more satisfying for both patient and doctor. Finally, we discuss and list some of the common diagnostic pitfalls in the assessment of functional neurologic disorders, looking at features that lead to erroneous diagnosis of neurologic disease (such as old age, la belle indifference, and lack of psychiatric comorbidity) and an erroneous diagnosis of a functional disorder (such as "bizarre" gait in stiff-person syndrome). PMID- 27719838 TI - The classification of conversion disorder (functional neurologic symptom disorder) in ICD and DSM. AB - The name given to functional neurologic symptoms has evolved over time in the different editions of the International Classification of Diseases (ICD) and the Diagnostic and Statistical Manual of Mental Disorders (DSM), reflecting a gradual move away from an etiologic conception rooted in hysterical conversion to an empiric phenomenologic one, emphasizing the central role of the neurologic examination and testing in demonstrating that the symptoms are incompatible with recognized neurologic disease pathophysiology, or are internally inconsistent. PMID- 27719839 TI - Neurologic diagnostic criteria for functional neurologic disorders. AB - The diagnosis of functional neurologic disorders can be challenging. In this chapter we review the diagnostic criteria and rating scales reported for functional/psychogenic sensorimotor disturbances, psychogenic nonepileptic seizures (PNES) and functional movement disorders (FMD). A recently published scale for sensorimotor signs has some limitations, but may help in the diagnosis, and four motor and two sensory signs have been reported as highly reliable. There is good evidence using eight specific signs for the differentiation of PNES from seizures. Recently, diagnostic criteria were developed for PNES; their sensitivity and specificity need to be evaluated. The definitive diagnosis of PNES can be made by recording typical positive features during the spells, and in a low proportion of cases, where the distinction with an organic etiology cannot easily be done, a normal electroencephalogram suggests the diagnosis. FMD diagnosis relies on diagnostic criteria, which have been refined over time and may be supplemented by laboratory tests in some phenotypes. Rating scales for PNES and FMD could be useful for severity measures, but several limitations remain to be addressed. PMID- 27719841 TI - Functional tremor. AB - Functional tremor is the commonest reported functional movement disorder. A confident clinical diagnosis of functional tremor is often possible based on the following "positive" criteria: a sudden tremor onset, unusual disease course, often with fluctuations or remissions, distractibility of the tremor if attention is removed from the affected body part, tremor entrainment, tremor variability, and a coactivation sign. Many patients show excessive exhaustion during examination. Other somatizations may be revealed in the medical history and patients may show additional functional neurologic symptoms and signs. In cases where the clinical diagnosis remains challenging, providing a "laboratory supported" level of certainty aids an early positive diagnosis. In rare cases, in which the distinction from Parkinson's disease is difficult, dopamine transporter single-photon emission computed tomography (DAT-SPECT) can be indicated. PMID- 27719840 TI - Functional limb weakness and paralysis. AB - Functional (psychogenic) limb weakness describes genuinely experienced limb power or paralysis in the absence of neurologic disease. The hallmark of functional limb weakness is the presence of internal inconsistency revealing a pattern of symptoms governed by abnormally focused attention. In this chapter we review the history and epidemiology of this clinical presentation as well as its subjective experience highlighting the detailed descriptions of authors at the end of the 19th and early 20th century. We discuss the relevance that physiological triggers such as injury and migraine and psychophysiological events such as panic and dissociation have to understanding of mechanism and treatment. We review many different positive diagnostic features, their basis in neurophysiological testing and present data on sensitivity and specificity. Diagnostic bedside tests with the most evidence are Hoover's sign, the hip abductor sign, drift without pronation, dragging gait, give way weakness and co-contraction. PMID- 27719842 TI - Functional dystonia. AB - Although currently lacking a sensitive and specific electrophysiologic battery test, functional (psychogenic) dystonia can sometimes be diagnosed with clinically definite certainty using available criteria. Certain regional phenotypes have been recognized as distinctive, such as unilateral lip and jaw deviation, laterocollis with ipsilateral shoulder elevation and contralateral shoulder depression, fixed wrist and finger flexion with relative sparing of the thumb and index fingers, and fixed foot plantar flexion and inversion. The pathophysiologic abnormalities in functional dystonia overlap substantially with those of organic dystonia, with similar impairments in cortical and spinal inhibition and somatosensory processing, but with emerging data suggesting abnormalities in regional blood flow and activation patterns on positron emission tomography and functional magnetic resonance imaging, respectively. Management of functional dystonia begins with compassionate and assertive debriefing of the diagnosis to ensure full acceptance by the patient, a critical step in enhancing the likelihood of success with physical rehabilitation, and psychodynamic or cognitive therapy. Physical therapy, with or without cognitive behavioral therapy, appears to be of benefit but has not yet been examined in a controlled fashion. While the prognosis remains grim for a substantial majority of patients, partly stemming from restricted mobility, delayed diagnosis, and inappropriate pharmacotherapy, early recognition and initiation of therapy stand to minimize iatrogenic harm and unnecessary laboratory investigations, and potentially reduce the long-term neurologic disability. PMID- 27719843 TI - Functional jerks, tics, and paroxysmal movement disorders. AB - Functional jerks are among the most common functional movement disorders. The diagnosis of functional jerks is mainly based on neurologic examination revealing specific positive clinical signs. Differentiation from other jerky movements, such as tics, organic myoclonus, and primary paroxysmal dyskinesias, can be difficult. In support of a functional jerk are: acute onset in adulthood, precipitation by a physical event, variable, complex, and inconsistent phenomenology, suggestibility, distractibility, entrainment and a Bereitschaftspotential preceding the movement. Although functional jerks and tics share many similarities, characteristics differentiating tics from functional jerks are: urge preceding the tic, childhood onset, rostrocaudal development of the symptoms, a positive family history of tics, attention-deficit hyperactivity disorder or obsessive-compulsive symptoms, and response to dopamine antagonist medication. To differentiate functional jerks from organic myoclonus, localization of the movements can give direction. Further features in support of organic myoclonus include: insidious onset, simple and consistent phenomenology, and response to benzodiazepines or antiepileptic medication. Primary paroxysmal dyskinesias and functional jerks share a paroxysmal nature. Leading in the differentiation between the two are: a positive family history, in combination with video recordings revealing a consistent symptom pattern in primary paroxysmal dyskinesias. In this chapter functional jerks and their differential diagnoses will be discussed in terms of epidemiology, symptom characteristics, disease course, psychopathology, and supportive neurophysiologic tests. PMID- 27719844 TI - Neurologic approaches to hysteria, psychogenic and functional disorders from the late 19th century onwards. AB - The history of functional neurologic disorders in the 20th century from the point of view of the neurologist is U-shaped. A flurry of interest between the 1880s and early 1920s gave way to lack of interest, skepticism, and concern about misdiagnosis. This was mirrored by increasing professional and geographic divisions between neurology and psychiatry after the First World War. In the 1990s the advent of imaging and other technology highlighted the positive nature of a functional diagnosis. Having been closer in the early 20th century but later more separate, these disorders are now once again the subject of academic and clinical interest, although arguably still very much on the fringes of neurology and neuropsychiatry. Revisiting older material provides a rich source of ideas and data for today's clinical researcher, but also offers cautionary tales of theories and treatments that led to stagnation rather than advancement of the field. Patterns of treatment do have a habit of repeating themselves, for example, the current enthusiasm for transcranial magnetic stimulation compared to the excitement about electrotherapy in the 19th century. For these reasons, an understanding of the history of functional disorders in neurology is arguably more important than it is for other areas of neurologic practice. PMID- 27719845 TI - Psychogenic (functional) parkinsonism. AB - Psychogenic parkinsonism (PP), although often quite disabling, is one of the least commonly reported subtypes of psychogenic movement disorders. There are certain features that help distinguish PP from idiopathic Parkinson's disease, such as abrupt onset, early disability, bilateral shaking and slowness, nondecremental slowness when performing repetitive movements, voluntary resistance against passive movement without cogwheel rigidity, distractibility, "give-way" weakness, stuttering speech, bizarre gait, and a variety of behavioral symptoms. While the diagnosis of PP is clinical, functional imaging evaluating the integrity of nigrostriatal pathways can help distinguish PP from other types of parkinsonism. PP can coexist in patients with organic parkinsonism, adding to the challenge of making a diagnosis of PP. Being cognizant of the clinical signs of psychogenic movement disorders, including PP, will lead to earlier diagnosis and hopefully improved outcomes. PMID- 27719846 TI - Functional gait disorder. AB - Gait disorder is a common accompaniment of functional neurologic disorders. The diagnosis of a functional or psychogenic gait is complex. It requires a sound knowledge of the range of phenomenology observed in organic movement disorders, the ability to evaluate and diagnose nonmovement disorder neurologic symptoms and signs, but additionally knowledge of potential musculoskeletal causes of gait disturbance. A stepwise approach to the analysis of the phenomenology and separation into four (sometimes overlapping) psychogenic gait syndromes is suggested to aid diagnosis: (1) movement disorder mimics; (2) neurologic (nonmovement disorder) mimics; (3) musculoskeletal or biomechanical mimics; and (4) isolated disequilibrium or balance disorders. Accurate diagnosis can lead to effective therapy. PMID- 27719847 TI - Functional sensory symptoms. AB - Functional (psychogenic) sensory symptoms are those in which the patient genuinely experiences alteration or absence of normal sensation in the absence of neurologic disease. The hallmark of functional sensory symptoms is the presence of internal inconsistency revealing a pattern of symptoms governed by abnormally focused attention. In this chapter we review the history of this area, different clinical presentations, diagnosis (including sensitivity of diagnostic tests), treatment, experimental studies, and prognosis. Altered sensation has been a feature of "hysteria" since descriptions of witchcraft in the middle ages. In the 19th century hysteric sensory stigmata were considered a hallmark of the condition. Despite this long history, relatively little attention has been paid to the topic of functional sensory disturbance, compared to functional limb weakness or functional movement disorders, with which it commonly coexists. There are recognizable clinical patterns, such as hemisensory disturbance and sensory disturbance finishing at the groin or shoulder, but in keeping with the literature on reliability of sensory signs in neurology in general, the evidence suggests that physical signs designed to make a positive diagnosis of functional sensory disorder may not be that reliable. There are sensory symptoms which are unusual but not functional (such as synesthesia and allochiria) but also functional sensory symptoms (such as complete loss of all pain) which are most unusual and probably worthy of independent study. PMID- 27719848 TI - Nonepileptic seizures - subjective phenomena. AB - Psychogenic nonepileptic seizures (PNES) superficially resemble epileptic seizures or syncope and most patients with PNES are initially misdiagnosed as having one of the latter two types of transient loss of consciousness. However, evidence suggests that the subjective seizure experience of PNES and its main differential diagnoses are as different as the causes of these three disorders. In spite of this, and regardless of the fact that PNES are considered a mental disorder in the current nosologies, research has only given limited attention to the subjective symptomatology of PNES. Instead, most phenomenologic research has focused on the visible manifestations of PNES and on physiologic parameters, neglecting patients' symptoms and experiences. This chapter gives an overview of qualitative and quantitative studies providing insights into subjective symptoms associated with PNES, drawing on a wide range of methodologies (questionnaires, self-reports, physiologic measures, linguistic analyses, and neuropsychologic experiments). After discussing the scope and limitations of these approaches in the context of this dissociative phenomenon, we discuss ictal, peri-ictal and interictal symptoms described by patients with PNES. We particularly focus on impairment of consciousness. PNES emerges as a clinically heterogeneous condition. We conclude with a discussion of the clinical significance of particular subjective symptoms for the engagement of patients in treatment, the formulation of treatment, and prognosis. PMID- 27719849 TI - Nonepileptic seizures - objective phenomena. AB - This chapter describes the evaluation process for the diagnosis of psychogenic nonepileptic seizures (PNES), which is determined based on concordance of the composite evidence available, including historic and physical exam findings, seizure semiology, and ictal/interictal electroencephalogram (EEG). No single clinical feature is pathognomonic of PNES. The diagnosis of PNES can be at times challenging, such as when seizure documentation on video-EEG cannot be readily achieved. A multicomponent approach to the diagnosis of PNES, with use of all available evidence, may facilitate diagnosis and then care of patients with PNES. Emerging evidence supports the use of symptom identification by the patient as part of the treatment of these patients. With advances in diagnostic methods and criteria, the diagnosis of PNES can be made reliably. PMID- 27719850 TI - A brief history of hysteria: From the ancient to the modern. AB - In this paper we discuss the history of hysteria from the Babylonian and Assyrian texts through to the situation as it appears to us at the end of the 19th century. We note the shifting emphasis on causation, earlier ideas being linked to uterine theories, later speculations moving to the brain, and then the mind. We note the persistence of the condition referred to as hysteria over the millennia and the fascination that the condition has held for physicians, neurologists, and psychiatrists since the origins of known medical texts. PMID- 27719851 TI - Psychogenic nonepileptic seizures: EEG and investigation. AB - In the investigation of psychogenic nonepileptic seizures (PNES), the main differential diagnoses are between convulsive PNES and tonic-clonic seizures, between swoon PNES and syncope, and between pseudoabsence PNES and absence seizures. For the best diagnostic certainty, events must be captured, ideally using video-electroencephalogram (EEG), including an electrocardiographic channel. The "video" part of video-EEG allows EEG changes (or lack of them) to be interpreted in the appropriate clinical context. When the diagnosis is based on less good data (e.g., video alone or EEG alone), then the limitations and constraints of the tests should borne in mind, and a lesser degree of certainty must be accepted. Tests such as serum prolactin (PRL) level and postictal EEG should be regarded as adjunctive rather than definitive. Excluding additional epilepsy with a good probability is not possible using investigations alone. In particular, one standard interictal EEG recording is of little value in excluding additional epilepsy, though multiple or prolonged recordings may offer additional sensitivity. PMID- 27719852 TI - Functional coma. AB - Functional coma - here defined as a prolonged motionless dissociative attack with absent or reduced response to external stimuli - is a relatively rare presentation. In this chapter we examine a wide range of terms used to describe states of unresponsiveness in which psychologic factors are relevant to etiology, such as depressive stupor, catatonia, nonepileptic "pseudostatus," and factitious disorders, and discuss the place of functional or psychogenic coma among these. Historically, diagnosis of functional coma has sometimes been reached after prolonged investigation and exclusion of other diagnoses. However, as is the case with other functional disorders, diagnosis should preferably be made on the basis of positive findings that provide evidence of inconsistency between an apparent comatose state and normal waking nervous system functioning. In our review of physical signs, we find some evidence for the presence of firm resistance to eye opening as reasonably sensitive and specific for functional coma, as well as the eye gaze sign, in which patients tend to look to the ground when turned on to one side. Noxious stimuli such as Harvey's sign (application of high-frequency vibrating tuning fork to the nasal mucosa) can also be helpful, although patients with this disorder are often remarkably unresponsive to usually painful stimuli, particularly as more commonly applied using sternal or nail bed pressure. The use of repeated painful stimuli is therefore not recommended. We also discuss the role of general anesthesia and other physiologic triggers to functional coma. PMID- 27719853 TI - Functional and simulated visual loss. AB - Nonorganic visual loss (NOVL) is the cause of a large number of referrals to neurologists and ophthalmologists and is a frequent area of overlap between neurologists, ophthalmologists, and psychiatrists. NOVL is the presence of visual impairment without an organic cause for disease despite a thorough and comprehensive investigation. A diagnosis of NOVL requires both the absence of any findings on examination and proof of the integrity and functioning of the visual system. Although sometimes a challenging diagnosis to make, there are a number of techniques and maneuvers which can be utilized fairly easily, either at the bedside or in the clinic, to help determine if a patient has NOVL. In some instances specialized testing, such as formal visual field testing, optical coherence tomography, visual evoked responses, electroretinogram, and various imaging modalities (magnetic resonance imaging) are performed to help determine if the cause of visual loss is organic or nonorganic. Once a diagnosis of NOVL is made, treatment centers around reassurance of the patient, close follow-up, and, if necessary, referral to a psychiatrist, as these patients may have underlying psychiatric disorders and a preceding strong emotional event leading to the current symptoms, and may be more likely to develop depression and anxiety. PMID- 27719854 TI - Functional eye movement disorders. AB - Functional (psychogenic) eye movement disorders are perhaps less established in the medical literature than other types of functional movement disorders. Patients may present with ocular symptoms (e.g., blurred vision or oscillopsia) or functional eye movements may be identified during the formal examination of the eyes in patients with other functional disorders. Convergence spasm is the most common functional eye movement disorder, but functional gaze limitation, functional eye oscillations (also termed "voluntary nystagmus"), and functional convergence paralysis may be underreported. This chapter reviews the different types of functional eye movement abnormalities and provides a practical framework for their diagnosis and management. PMID- 27719855 TI - Functional facial and tongue movement disorders. AB - Functional movement disorders (FMDs) affecting the eyelids, tongue, and other facial muscles are often underrecognized because their phenomenology has not been fully characterized. Nevertheless, these disorders are more common than previously thought. In this chapter we will discuss the phenomenology as well as the clinical and instrumental diagnosis of facial FMDs. Facial FMDs should be considered when a patient exhibits any combination of the following features: (1) fixed unilateral facial contractions, especially with lower lip, with or without ipsilateral jaw involvement, of maximal severity at onset; (2) inconsistent features such as changes in side and pattern during or between examination; (3) associated somatoform or nonphysiologic sensory or motor findings; (4) reduction or abolition of facial spasm with distraction; (5) response to suggestion or psychotherapy; (6) rapid onset and/or spontaneous remissions; and (7) normal neurologic examination. Supportive features are young age, female gender, and associated medical conditions such as depression, headaches, facial pain, fibromyalgia, or irritable-bowel syndrome. Finally, the differential diagnosis with the organic counterparts will be also addressed, particularly with respect to blepharospasm, oromandibular dystonia, and hemifacial spasm. PMID- 27719856 TI - Functional auditory disorders. AB - There are a number of auditory symptom syndromes that can develop without an organic basis. Some of these, such as nonorganic hearing loss, affect populations similar to those presenting with functional somatosensory and motor symptoms, while others, such as musical hallucination, affect populations with a significantly different demographic and require different treatment strategies. Many of these conditions owe their origin to measurably abnormal peripheral sensory pathology or brain network activity, but their pathological impact is often due, at least in part, to overamplification of the salience of these phenomena. For each syndrome, this chapter briefly outlines a definition, demographics, investigations, putative mechanisms, and treatment strategies. Consideration is given to what extent they can be considered to have a functional basis. Treatments are in many cases pragmatic and rudimentary, needing more work to be done in integrating insights from behavioral and cognitive psychology to auditory neuroscience. The audiology literature has historically equated the term functional with malingering, although this perception is, thankfully, slowly changing. These disorders transcend the disciplines of audiology, otorhinolaryngology, neurology and psychiatry, and a multidisciplinary approach is often rewarding. PMID- 27719857 TI - Freud's hysteria and its legacy. AB - Though Freud was himself interested in neurologic disorders, the model of hysteria he developed - of the repression of painful experiences, and their conversion into physical symptoms - made the disorder psychiatric, as the increasingly complex explanations came to rely on the "meaning" of events, which could not easily be understood neurologically. This evolved to become a prototype for psychiatric illness more broadly, a model which, though challenged by the First World War, enjoyed great success, notably in the USA, dominating psychiatric thinking for most of the 20th century. Concerns about the empiric basis for his ideas latterly led to a rapid decline in their importance, however, exemplified by 1980's "etiologically neutral" DSM-III. Hysteria, now renamed conversion disorder, retained its Freudian explanation for another 30 years, but as psychiatry lost its faith in Freud, so psychiatrists stopped seeing the disorder he had made theirs, and returned it once more to neurology. PMID- 27719858 TI - Functional speech disorders: clinical manifestations, diagnosis, and management. AB - Acquired psychogenic or functional speech disorders are a subtype of functional neurologic disorders. They can mimic organic speech disorders and, although any aspect of speech production can be affected, they manifest most often as dysphonia, stuttering, or prosodic abnormalities. This chapter reviews the prevalence of functional speech disorders, the spectrum of their primary clinical characteristics, and the clues that help distinguish them from organic neurologic diseases affecting the sensorimotor networks involved in speech production. Diagnosis of a speech disorder as functional can be supported by sometimes rapidly achieved positive outcomes of symptomatic speech therapy. The general principles of such therapy are reviewed. PMID- 27719859 TI - Functional voice disorders: Clinical presentations and differential diagnosis. AB - In this chapter, an overview of the heterogeneous group of functional voice disorders is given, including the psychogenic voice disorder (PVD) and hyperfunctional or muscle tension voice disorder (MTVD) subgroups. Reference is made to prevalence and demographic data, with empiric evidence for psychosocial factors commonly associated with the onset and maintenance of these disorders. Clinical features that distinguish between the different presentations of PVD and MTVD are described. While there are some shared characteristics, key differences between these two subgroups indicate that PVD more closely resembles the psychogenic movement disorders and a range of other functional neurologic disorders. Assessment procedures and auditory-perceptual features of the voice that distinguish these disorders from the neurologically based voice disorders are discussed, with case examples highlighting ambiguous features that may influence differential diagnosis. The clinical profiles of PVD and MTVD affirm approaches to clinical management by speech-language pathologists that integrate symptomatic behavioral voice therapy with "top-down" models of counseling or psychotherapy. They also support the proposition that PVD may be construed as a subtype of functional neurologic disorders. PMID- 27719860 TI - Psychologic/functional forms of memory disorder. AB - In this chapter, we discuss the wide variety of patients who may attend a memory clinic or other health services presenting with memory symptoms but who do not have dementia. These diagnoses may include a wide range of neurologic and neuropsychiatric disorders; in this chapter we will focus on other causes of memory symptoms which may be labeled psychologic or functional, or be more obviously part of an established psychiatric disorder. We describe the differential categorization recently posited by Stone et al. (2015), and consider important aspects of assessment and management in these cases. PMID- 27719861 TI - Functional (dissociative) retrograde amnesia. AB - Retrograde amnesia is described as condition which can occur after direct brain damage, but which occurs more frequently as a result of a psychiatric illness. In order to understand the amnesic condition, content-based divisions of memory are defined. The measurement of retrograde memory is discussed and the dichotomy between "organic" and "psychogenic" retrograde amnesia is questioned. Briefly, brain damage-related etiologies of retrograde amnesia are mentioned. The major portion of the review is devoted to dissociative amnesia (also named psychogenic or functional amnesia) and to the discussion of an overlap between psychogenic and "brain organic" forms of amnesia. The "inability of access hypothesis" is proposed to account for most of both the organic and psychogenic (dissociative) patients with primarily retrograde amnesia. Questions such as why recovery from retrograde amnesia can occur in retrograde (dissociative) amnesia, and why long term new learning of episodic-autobiographic episodes is possible, are addressed. It is concluded that research on retrograde amnesia research is still in its infancy, as the neural correlates of memory storage are still unknown. It is argued that the recollection of episodic-autobiographic episodes most likely involves frontotemporal regions of the right hemisphere, a region which appears to be hypometabolic in patients with dissociative amnesia. PMID- 27719862 TI - Functional (psychogenic) dizziness. AB - Functional and psychiatric disorders that cause vestibular symptoms (i.e., vertigo, unsteadiness, and dizziness) are common. In fact, they are more common than many well-known structural vestibular disorders. Neurologists and otologists are more likely to encounter patients with vestibular symptoms due to persistent postural-perceptual dizziness or panic disorder than Meniere's disease or bilateral vestibular loss. Successful approaches to identifying functional and psychiatric causes of vestibular symptoms can be incorporated into existing practices without much difficulty. The greatest challenge is to set aside dichotomous thinking that strongly emphasizes investigations of structural diseases in favor of a three-pronged approach that assesses structural, functional, and psychiatric disorders simultaneously. The pathophysiologic mechanisms underlying functional and psychiatric causes of vestibular symptoms are better understood than many clinicians realize. Research methods such as advanced posturographic analysis and functional brain imaging will push this knowledge further in the next few years. Treatment plans that include patient education, vestibular rehabilitation, cognitive and behavioral therapies, and medications substantially reduce morbidity and offer the potential for sustained remission when applied systematically. Diagnostic and therapeutic approaches are necessarily multidisciplinary in nature, but they are well within the purview of collaborative care teams or networks of clinicians coordinated with the neurologists and otologists whom patients consult first. PMID- 27719863 TI - Urologic symptoms and functional neurologic disorders. AB - The term functional urologic disorders covers a wide range of conditions related broadly to altered function rather than structure of the lower urinary tract, mainly of impaired urine voiding or storage. Confusingly, for a neurologic readership, these disorders of function may often be due to a urologic, gynecologic, or neurologic cause. However, there is a subset of functional urologic disorders where the cause remains uncertain and, in this chapter, we describe the clinical features of these disorders in turn: psychogenic urinary retention; Fowler's syndrome; paruresis (shy-bladder syndrome); dysfunctional voiding; idiopathic overactive bladder, and interstitial cystitis/bladder pain syndrome. Some of these overlap in terms of symptoms, but have become historically separated. Psychogenic urinary retention in particular has now largely been abandoned as a concept, in part because of the finding of specific urethral electromyogram findings in patients with this symptom now described as having Fowler's syndrome, and their successful treatment with sacral neurostimulation. In this chapter we review the poorly researched interface between these "idiopathic" functional urologic disorders and other functional disorders (e.g., irritable-bowel syndrome, fibromyalgia) as well as specifically functional neurologic disorders. We conclude that there may be a relationship and overlap between them and that this requires further research, especially in those idiopathic functional urologic disorders which involve disorders of the urethral sphincter (i.e., voluntary muscle). PMID- 27719864 TI - Epidemiology. AB - The epidemiology of functional neurologic disorders (FND) is complex and has been hampered over the years by a lack of clear definition, with previous definitions struggling with an uneasy mix of both physical and psychologic components. The recent changes in DSM-5 to a definition based on positive identification of physical symptoms which are incongruent and inconsistent with neurologic disease and the lack of need for any associated psychopathology represent a significant step forward in clarifying the disorder. On this basis, FND account for approximately 6% of neurology outpatient contacts and putative community incidence rates of 4-12 per 100 000 per annum. Comorbid neurologic disease occurs in around 10% of cases. The diagnosis is reliable, with revision rates less than 5%. Of note, this revision rate was consistent prior to the widespread utilization of computed tomography and magnetic resonance imaging. FND symptoms are disabling and associated with significant distress. They are more common in women and have a peak incidence between the ages of 35 and 50; however the presentation is common in men and throughout the lifespan. The issues surrounding case definition, ascertainment, misdiagnosis, and risk factors are discussed in detail. PMID- 27719865 TI - Functional disorders of swallowing. AB - Swallowing involves complex coordination of the neuromuscular anatomy and physiology of the oropharynx and esophagus, controlled by the enteric and central nervous systems. Dysphagia is classified as either oropharyngeal or esophageal and results from mechanical or structural disturbances. Videofluoroscopy, fiberoptic endoscopic evaluation of swallowing, barium swallow, manometry, and endoscopy are common modalities utilized in diagnosis, but none is as important as a patient's history. Functional dysphagia is a diagnosis of exclusion and is based on Rome criteria. Its mechanism is unknown but potentially related to visceral hypersensitivity, inappropriate pain perception, or unidentified contraction abnormalities. Its management is mainly supportive; however, there is literature to suggest, but not confirm, benefit with the use of antidepressants. Continued understanding of functional dysphagia and other functional esophageal disorders, including globus sensation, will require further investigation into diagnostic algorithms and finding treatment methods. PMID- 27719866 TI - Pediatric functional neurologic symptoms. AB - Functional neurologic disorders (FND) of children have many similarities to those of adults, and there is a potential to learn much from the study of FND in children. In this chapter we discuss multiple aspects of pediatric FND. These include their frequency, historic features, the diagnosis, and controversies over the nature of FND and the "correct" name that should be used. We also discuss methods of informing the child and family of the diagnosis, treatment, and prognosis. FND of children typically affect girls in the 10-14-years age range. The presentation is often polysymptomatic, with pain and lethargy accompanying loss of motor function. A common situation is a perfectionistic child who has taken on too much in her academic, sporting, cultural, and social life. Some children respond readily to treatment, but others have a prolonged illness. PMID- 27719867 TI - Posttraumatic functional movement disorders. AB - Traumatic injury to the nervous system may account for a range of neurologic symptoms. Trauma location and severity are important determinants of the resulting symptoms. In severe head injury with structural brain abnormalities, the occurrence of trauma-induced movement disorders, most commonly hyperkinesias such as tremor and dystonia, is well recognized and its diagnosis straightforward. However, the association of minor traumatic events, which do not lead to significant persistent structural brain damage, with the onset of movement disorders is more contentious. The lack of clear clinical-neuroanatomic (or symptom lesion) correlations in these cases, the variable timing between traumatic event and symptom onset, but also the presence of unusual clinical features in a number of such patients, which overlap with signs encountered in patients with functional neurologic disorders, contribute to this controversy. The purpose of this chapter is to provide an overview of the movement disorders, most notably dystonia, that have been associated with peripheral trauma and focus on their unusual characteristics, as well as their overlap with functional neurologic disorders. We will then provide details on pathophysiologic views that relate minor peripheral injuries to the development of movement disorders and compare them to knowledge from primary organic and functional movement disorders. Finally, we will comment on the appropriate management of these disorders. PMID- 27719868 TI - Factitious disorders and malingering in relation to functional neurologic disorders. AB - Interest in malingering has grown in recent years, and is reflected in the exponential increase in academic publications since 1990. Although malingering is more commonly detected in medicolegal practice, it is not an all-or-nothing presentation and moreover can vary in the extent of presentation. As a nonmedical disorder, the challenge for clinical practice remains that malingering by definition is intentional and deliberate. As such, clinical skills alone are often insufficient to detect it and we describe psychometric tests such as symptom validity tests and relevant nonmedical investigations. Finally, we describe those areas of neurologic practice where symptom exaggeration and deception are more likely to occur, e.g., postconcussional syndrome, psychogenic nonepileptic seizures, motor weakness and movement disorders, and chronic pain. Factitious disorders are rare in clinical practice and their detection depends largely on the level of clinical suspicion supported by the systematic collection of relevant information from a variety of sources. In this chapter we challenge the accepted DSM-5 definition of factitious disorder and suggest that the traditional glossaries have neglected the extent to which a person's reported symptoms can be considered a product of intentional choice or selective psychopathology largely beyond the subject's voluntary control, or more likely, both. We present evidence to suggest that neurologists preferentially diagnose factitious presentations in healthcare workers as "hysterical," possibly to avoid the stigma of simulated illness. PMID- 27719869 TI - Prognosis of functional neurologic disorders. AB - The prognosis of functional (psychogenic) neurologic disorders is important in being able to help answer patients' and carers' questions, determine whether treatment is worthwhile, and to find out which factors predict outcome. We reviewed data on prognosis of functional neurologic disorders from two systematic reviews on functional motor disorders and dissociative (nonepileptic) seizures as well as additional studies on functional visual and sensory symptoms. Methodologic problems include heterogeneity in studied samples and outcome measures, diagnostic suspicion and referral bias, small size and retrospective design of available studies, possible treatments during follow-up, and literature review bias. With these caveats, the prognosis of functional neurologic disorders does appear to be generally unfavorable. In most studies, functional motor symptoms and psychogenic nonepileptic attacks remain the same or are worse in the majority of patients at follow-up. Measures of quality of life and working status were often poor at follow-up. Frequency of misdiagnosis at follow-up was as low as other neurologic and psychiatric disorders. Long duration of symptoms was the most distinct negative predictor. Early diagnosis and young age seem to predict good outcome. Emotional disorders and personality disorders were inconsistent predictors. Litigation and state benefits were found to be negative predictors in some studies, but others found they did not influence outcome. PMID- 27719870 TI - Explanation as treatment for functional neurologic disorders. AB - There is widespread agreement that the way health professionals communicate the diagnosis of functional neurologic disorders (FND) has a central role in treatment, as it does arguably for most conditions. In this chapter we discuss barriers to effective diagnosis, different models of explanation and evidence regarding the importance of effective communication of the diagnosis in FND, especially movement disorders, and dissociative (nonepileptic) seizures. Debates and disagreements about how to go about this task often reflect different theoretic models held by health professionals rather than evidence. More evidence is required to know whether an initial emphasis on one model is more or less effective than another (e.g., a functional model vs. a psychologic model). We conclude, however, that there are a number of generic components to effective explanation shared by most authors on the topic that form the basis of a consensus. These include taking the patient seriously, giving the problem a diagnostic label, explaining the rationale for the diagnosis, some discussion of how the symptoms arise, emphasis on the potential for reversibility (rather than damage), and effective triage and referral for other treatment where appropriate. Although explanation can sometimes be therapeutic on its own, its role is probably more important as a facilitator to other therapy, including self-help, physical treatments, and psychotherapy. PMID- 27719871 TI - Physical treatment of functional neurologic disorders. AB - Physical interventions are widely considered an important part of treatment of functional neurologic disorders (FNDs). The evidence base for physical interventions has been limited to a collection of case series, but the recent publication of several large cohort studies and a randomized controlled trial have provided stronger evidence to support its use. While the evidence for efficacy appears to be promising, details on how this should be delivered remain limited, perhaps due to the dominance of psychologically focused etiologic models. A move towards understanding how the symptoms of FND are generated on a neurobiologic level has resulted in an expansion of pathophysiologic models providing a clearer rationale for physical treatment. In this context, the motor symptoms of FND can be considered as learnt patterns of movement, driven by attention and belief. Physical treatment aims to retrain movement by redirecting attention and addressing unhelpful illness beliefs and behaviors. The patient's problems should be considered in a broad biopsychosocial framework where symptom predisposing, precipitating, and perpetuating factors can be addressed within a multidisciplinary environment as a gold standard. Further research is required to refine interventions and create evidence-based treatment guidelines. PMID- 27719872 TI - Psychologic treatment of functional neurologic disorders. AB - The management of patients with functional neurologic disorders poses many challenges. Psychologic treatments may well start at the point of delivery of the diagnosis, when careful explanations about the nature of the disorder have to be given to the patient and possibly also relatives/carers. Different conceptual models may assist in explaining the factors underlying the presentation, two of which (functional and dissociative) are briefly outlined here. The challenges for neurologists and psychiatrists of delivering a psychologic formulation as part of the diagnosis delivery are considered, along with the importance of clear communication between professionals involved in the patient's care. Existing literature on treatments incorporating psychologic components suggests that, despite limitations in the study designs and the potential bias in some outcome evaluations, there is evidence to support the use of psychologic interventions for at least some functional neurologic disorders, although larger and better designed studies are required in this area. PMID- 27719873 TI - Hypnosis as therapy for functional neurologic disorders. AB - Suggestion in hypnosis has been applied to the treatment of functional neurologic symptoms since the earliest descriptions of hypnosis in the 19th century. Suggestion in this sense refers to an intentional communication of beliefs or ideas, whether verbally or nonverbally, to produce subjectively convincing changes in experience and behavior. The recognition of suggestion as a psychologic process with therapeutic applications was closely linked to the derivation of hypnosis from earlier healing practices. Animal magnetism, the immediate precursor of hypnosis, arrived at a psychologic concept of suggestion along with other ideas and practices which were then incorporated into hypnosis. Before then, other forms of magnetism and ritual healing practices such as exorcism involved unintentionally suggestive verbal and nonverbal stimuli. We consider the derivation of hypnosis from these practices not only to illustrate the range of suggestive processes, but also the consistency with which suggestion has been applied to the production and removal of dissociative and functional neurologic symptoms over many centuries. Nineteenth-century practitioners treated functional symptoms with induction of hypnosis per se; imperative suggestions, or commands for specific effects; "medical clairvoyance" in hypnotic trance, in which patients diagnosed their own condition and predicted the time and manner of their recovery; and suggestion without prior hypnosis, known as "fascination" or "psychotherapeutics." Modern treatments largely involve different types of imperative suggestion with or without hypnosis. However, the therapeutic application of suggestion in hypnosis to functional and other symptoms waned in the first half of the 20th century under the separate pressures of behaviorism and psychoanalysis. In recent decades suggestion in hypnosis has been more widely applied to treating functional neurologic symptoms. Suggestion is typically applied within the context of other treatment approaches, such as cognitive behavioral, rehabilitative, or psychodynamic therapy. Suggestions are generally symptom-focused (designed to resolve a symptom) or exploratory (using methods such as revivification or age regression to explore experiences associated with symptom onset). The evidence base is dominated by case studies and series, with a paucity of randomized controlled trials. Future evaluation studies should allow for the fact that suggestion with or without hypnosis is a component of broader treatment interventions adapted to a wide range of symptoms and presentations. An important role of the concept of suggestion in the management of functional neurologic symptoms is to raise awareness of how interactions with clinicians and wider clinical contexts can alter expectancies and beliefs of patients in ways that influence the onset, course, and remission of symptoms. PMID- 27719874 TI - Nature of the placebo and nocebo effect in relation to functional neurologic disorders. AB - Placebos have long been considered a nuisance in clinical research, for they have always been used as comparators for the validation of new treatments. By contrast, today they represent an active field of research, and, due to the involvement of many mechanisms, the study of the placebo effect can actually be viewed as a melting pot of concepts and ideas for neuroscience. There is not a single placebo effect, but many, with different mechanisms across different medical conditions and therapeutic interventions. Expectation, anxiety, and reward are all involved, as well as a variety of learning phenomena and genetic variants. The most productive models to better understand the neurobiology of the placebo effect are pain and Parkinson's disease. In these medical conditions, several neurotransmitters have been identified, such as endogenous opioids, cholecystokinin, dopamine, as well as lipidic mediators, for example, endocannabinoids and prostaglandins. Since the placebo effect is basically a psychosocial context effect, these data indicate that different social stimuli, such as words and therapeutic rituals, may change the chemistry of the patient's brain, and these effects are similar to those induced by drugs. PMID- 27719875 TI - The role of placebo in the diagnosis and treatment of functional neurologic disorders. AB - Placebo therapy can produce meaningful, clinical relief for a variety of conditions. While placebos are not without their ethically fraught history, they continue to be used, largely covertly, even today. Because the prognosis for psychogenic disorders is often poor and recovery may be highly dependent on the patient's belief in the diagnosis and treatment regimen, some physicians find placebo therapy for psychogenic disorders compelling, but also particularly contentious. Yet placebos also have a long tradition of being used for provocative diagnosis (wherein placebo is used to elicit and/or terminate the symptoms as a way of diagnosing symptoms as "psychogenic"). In this chapter we discuss cases describing placebo as therapy for psychogenic disorders and the challenges related to embedded Cartesian beliefs in Western medicine. The legitimate ethical reservations against placebo therapy, in general, have been related to assumptions about their "inertness" and a requirement for deception, both which are being refuted by emerging data. In this chapter, we also re evaluate the concerns associated with placebo therapy for psychogenic disorders by asking, "Are we harming patients by withholding placebo treatment?" PMID- 27719876 TI - Neurophysiologic studies of functional neurologic disorders. AB - Functional neurologic disorders are largely genuine and represent conversion disorders, where the dysfunction is unconscious, but there are some that are factitious, where the abnormality is feigned and conscious. Malingering, which can have the same manifestations, is similarly feigned, but not considered a genuine disease. There are no good methods for differentiating these three entities at the present time. Physiologic studies of functional weakness and sensory loss reveal normal functioning of primary motor and sensory cortex, but abnormalities of premotor cortex and association cortices. This suggests a top down influence creating the dysfunction. Studies of functional tremor and myoclonus show that these disorders utilize normal voluntary motor structures to produce the involuntary movements, again suggesting a higher-level abnormality. Agency is abnormal and studies shows that dysfunction of the temporoparietal junction may be a correlate. The limbic system is overactive and might initiate involuntary movements, but the mechanism for this is not known. The limbic system would then be the source of top-down dysfunction. It can be speculated that the involuntary movements are involuntary due to lack of proper feedforward signaling. PMID- 27719877 TI - Transcranial magnetic stimulation and sedation as treatment for functional neurologic disorders. AB - Functional neurologic disorder (FND), also known as conversion disorder, is common and often associated with a poor prognosis. It has been relatively neglected by research and as such there is a conspicuous lack of evidence-based treatments. Physical and psychologic therapies are the main treatment modalities, over and above reassurance and sensitive explanation of the diagnosis. However there are two other historic treatments that have seen a recent resurgence of interest and use. The first is electric stimulation, which was initially pioneered with direct stimulation of nerves but now used indirectly (and therefore noninvasively) in the form of transcranial magnetic stimulation (TMS). The second is (therapeutic) sedation, previously known as "abreaction," where it was mostly used in the context of psychologic investigation and treatment, but now increasingly advocated during rehabilitation as a way to therapeutically demonstrate reversibility of symptoms. This chapter introduces the background of these treatment modalities, their evolution into their current applications before critically evaluating their current evidence base and exploring possible mechanisms of action. It also tentatively suggests when they should be considered in current practice and briefly considers their future potential. In summary there is encouraging preliminary evidence to suggest that both TMS and sedation may be effective treatments for FNDs. PMID- 27719878 TI - Inpatient treatment for functional neurologic disorders. AB - Patients with functional neurologic disorders present to clinicians with a variety of symptomatic manifestations, with various levels of severity, chronicity, and comorbidity, as well as with various degrees of past adversity, intrinsic resilience, and available external support. Clearly, treatment must be individualized. For those patients who have been severely or chronically impaired, especially if adequate prior outpatient treatments have failed, inpatient treatment that integrates the various modalities outlined here provides a rational route of rescue from a course otherwise potentially characterized by protracted dependence and disability. Based on the data currently available, we believe this treatment approach is worthy of further study to refine the component treatment strategies and enhance the potentially most effective ingredients. For patients with severe levels of disability, who could be managed in a multimodal day-treatment program, that approach also warrants further consideration. PMID- 27719879 TI - Imaging studies of functional neurologic disorders. AB - Brain imaging techniques provide unprecedented opportunities to study the neural mechanisms underlying functional neurologic disorder (FND, or conversion disorder), which have long remained a mystery and clinical challenge for physicians, as they arise with no apparent underlying organic disease. One of the first questions addressed by imaging studies concerned whether motor conversion deficits (e.g., hysteric paralysis) represent a form of (perhaps unconscious) simulation, a mere absence of voluntary movement, or more specific disturbances in motor control (such as abnormal inhibition). Converging evidence from several studies using different techniques and paradigms has now demonstrated distinctive brain activation patterns associated with functional deficits, unlike those seen in actors simulating similar deficits. Thus, patients with motor FND show consistent hypoactivation of both cortical and subcortical motor pathways, with frequent increases in other brain areas within the limbic system, but no recruitment of prefrontal regions usually associated with voluntary motor inhibition. Other studies point to a dysfunction in sensorimotor integration and agency - related to parietal dysfunction - and abnormal motor planning related to supplementary motor area and prefrontal areas. These findings not only suggest that functional symptoms reflect a genuine brain dysfunction, but also give new insights into how they are produced. However, fewer studies attempted to understand why these symptoms are produced and linked to potential psychologic or emotional risk/triggering factors. Results from such studies point towards abnormal limbic regulation with heightened emotional arousal and amygdalar activity, potentially related to engagement of defense systems and stereotyped motor behaviors, mediated by medial prefrontal cortex and subcortical structures, including the periaqueductal gray area and basal ganglia. In addition, across different symptom domains, several studies reported abnormal recruitment of ventromedial prefrontal cortex (vmPFC), a region known to regulate emotion appraisal, memory retrieval, and self-reflective representations. The vmPFC might provide important modulatory signals to both cortical and subcortical sensorimotor, visual, and even memory circuits, promoting maladaptive self protective behaviors based on personal affective appraisals of particular events. A better understanding of such a role of vmPFC in FND may help link how and why these symptoms are produced. Further research is also needed to determine brain activation patterns associated with FND across different types of deficits and different evolution stages (e.g., acute vs. chronic vs. recovered). PMID- 27719880 TI - Dissociation and functional neurologic disorders. AB - Dissociation has been cited as a possible psychologic mechanism underpinning functional neurologic disorders (FND) since the 19th century. Since that time, changes in psychiatric classification have created confusion about what the term dissociation actually means. The available evidence suggests that it now refers to at least two qualitatively distinct types of phenomena: detachment (an altered state of consciousness characterized by a sense of separation from the self or world) and compartmentalization (a reversible loss of voluntary control over apparently intact processes and functions), as well as their underlying mechanisms. This chapter considers some of the problems with conflating these phenomena under a single heading as well as the relationship between detachment, compartmentalization, and FND. It is argued that FNDs are fundamentally compartmentalization disorders, but that detachment is often part of the clinical picture and may contribute to the development and maintenance of functional symptoms in many cases. By this view, understanding compartmentalization requires an appreciation of the mechanisms involved in controlling and accessing mental processes and contents. Two possible mechanisms in this regard are described and the evidence for these is considered, followed by a discussion of clinical and empiric implications. PMID- 27719881 TI - Hypnosis as a model of functional neurologic disorders. AB - In the 19th century it was recognized that neurologic symptoms could be caused by "morbid ideation" as well as organic lesions. The subsequent observation that hysteric (now called "functional") symptoms could be produced and removed by hypnotic suggestion led Charcot to hypothesize that suggestion mediated the effects of ideas on hysteric symptoms through as yet unknown effects on brain activity. The advent of neuroimaging 100 years later revealed strikingly similar neural correlates in experiments matching functional symptoms with clinical analogs created by suggestion. Integrative models of suggested and functional symptoms regard these alterations in brain function as the endpoint of a broader set of changes in information processing due to suggestion. These accounts consider that suggestions alter experience by mobilizing representations from memory systems, and altering causal attributions, during preconscious processing which alters the content of what is provided to our highly edited subjective version of the world. Hypnosis as a model for functional symptoms draws attention to how radical alterations in experience and behavior can conform to the content of mental representations through effects on cognition and brain function. Experimental study of functional symptoms and their suggested counterparts in hypnosis reveals the distinct and shared processes through which this can occur. PMID- 27719882 TI - Preface. PMID- 27719883 TI - Foreword. PMID- 27719884 TI - Effect of molecular weight on the transepithelial transport and peptidase degradation of casein-derived peptides by using Caco-2 cell model. AB - The transepithelial transport routes of casein-derived peptides with different molecular weights (MWs) were investigated using a Caco-2 cell monolayer. The peptidase hydrolysis during transport was also studied. The results indicate that the paracellular route was the main pathway for F1 (1600-1300Da) and F2 (1000 500Da), and the bioavailabilities were 10.66% and 9.54%, respectively. Peptidase hydrolysis results reveal that brush-border peptidases (BBPs) as well as some other peptidases were responsible for peptide degradation in the paracellular route. The maximum hydrolysis rate of the former was 6.91 and 5.59MUM Gly/min for the latter. However, PepT1 was involved in the transport of F3 (<500Da) and its bioavailability was 16.23%. BBPs were the main peptidases involved in the PepT1 transport and the maximum hydrolysis rate was 11.4MUM Gly/min. Furthermore, we found that the amino acid sequence of di- and tripeptides might affect their bioavailabilities significantly. PMID- 27719885 TI - Contribution of individual phenolics to antioxidant activity and in vitro digestibility of wild rices (Zizania aquatica L.). AB - Zizania aquatica L. was analysed for total flavonoids, phenolics and HPLC profile in both free and bound phenolic fractions. The highest content of flavonoids (378 455mgRE/kg) was detected in bound fractions, while the highest polyphenols content (1061-2988mgGAE/kg) was determined in free fractions. Additionally, predominant phenolics were identified. To understand the contribution of individual phenolics to an antioxidant activity their mutual correlations were evaluated. Regarding free flavonoids, the main contributors to an antioxidant activity (r>0.7111) were epigallocatechin, epicatechin and rutin; while epicatechin, quercetin and rutin were the main contributors in bound fractions (r>0.6868). Concerning free phenolic acids, the main contributors to an antioxidant activity (r>0.7585) were ferulic, vanillic, ellagic, sinapic and syringic acids; while caffeic, sinapic, syringic, o-coumaric, p-hydroxy benzoic, vanillic, protocatechuic, gallic and cinnamic acids were the main contributors in bound fractions of wild rice (r>0.6538). Finally, in vitro organic matter and dry matter digestibility were assessed. PMID- 27719886 TI - Preparation and properties of octenyl succinate beta-cyclodextrin and its application as an emulsion stabilizer. AB - The aim of this study was to synthesize and characterize the octenyl succinic beta-cyclodextrin (OS-beta-CD) and assess its application as a potential emulsion stabilizer. OS-beta-CD was prepared by esterifying beta-CD with OSA under alkaline conditions. The properties of OS-beta-CD were characterized by Fourier transform infrared, 13C and 1H NMR spectroscopy, X-ray diffraction (XRD), which demonstrated that OS groups had been introduced into the beta-CD molecules and most of OS substitution occurred at the C-6 hydroxyl group of glycosyl units. The properties of emulsions stabilized by beta-CD and OS-beta-CD were evaluated via surface and interface tensiometry, determination of the creaming index and droplet size. The results showed that emulsions stabilized by beta-CD broke just after 24h storage at 25 degrees C. The emulsions prepared by OS-beta-CD with all degree of substitution (DS) possessed a smaller oil droplet size and improved storage stability compared with that of the emulsion generated using beta-CD.

AB - A new colorimetric pH indicator film was developed using agar, potato starch, and natural dyes extracted from purple sweet potato, Ipomoea batatas. Both agar and potato starch are solid matrices used to immobilize natural dyes, anthocyanins. The ultraviolet-visible (UV-vis) spectrum of anthocyanin extract solutions and agar/potato starch films with anthocyanins showed color variations to different pH values (pH 2.0-10.0). Fourier transform infrared (FT-IR) and UV-vis region spectra showed compatibility between agar, starch, and anthocyanin extracts. Color variations of pH indicator films were measured by a colorimeter after immersion in different pH buffers. An application test was conducted for potential use as a meat spoilage sensor. The pH indicator films showed pH changes and spoilage point of pork samples, changing from red to green. Therefore, the developed pH indicator films could be used as a diagnostic tool for the detection of food spoilage.

AB - Meat industry needs to reduce salt in their products due to health issues. The present study evaluated the effect of salt reduction from 6% to 3% in two Portuguese traditional blood dry-cured sausages. Physicochemical and microbiological parameters, biogenic amines, fatty acids and texture profiles and sensory panel evaluations were considered. Differences due to salt reduction were perceptible in a faint decline of water activity, which slightly favoured microbial growth. Total biogenic amines content ranged from 88.86 to 796.68mgkg-1 fresh matter, with higher amounts, particularly of cadaverine, histamine and tyramine, in low-salt products. Still, histamine and other vasoactive amines remained at low levels, thus not affecting consumers' health. Regarding fatty acids, no significant differences were observed due to salt. However, texture profile analysis revealed lower resilience and cohesiveness in low-salt products, although no textural changes were observed by the sensory panel. Nevertheless, low-salt sausages were clearly preferred by panellists. PMID- 27719889 TI - Influence of non-starchy polysaccharides on barley milling behavior and evaluating bioactive composition of milled fractions. AB - Hulless barley cultivars grown at various altitudes were subjected to different conditioning treatments prior to roller milling. Amongst all treatments, conditioning grains to a moisture content of 14% for 30min was found to be optimum. The bran fractions displayed greater levels of non-starchy polysaccharides and bioactive components as compared to refined flour fraction. The presence of greater levels of beta-glucan in whole barley flour and bran of high altitude cultivars affected the refined flour yield inversely. Cultivars having higher total and insoluble arabinoxylans also resulted in lower flour yields (R=-0.76; R=-0.73). The damaged starch content of barley cultivars ranged between 5.1% and 8.7% which correlated positively with the content of beta glucans (up to R=0.77) and arabinoxylans (up to R=0.80) in bran and refined flour fractions. The anthocyanin and total phenolic contents of refined flours ranged between 3.9-7.6MUg/g and 1299-1607MUg FAE/g and was higher for high altitude cultivars. PMID- 27719890 TI - Free radical scavenging potency of quercetin catecholic colonic metabolites: Thermodynamics of 2H+/2e- processes. AB - Reaction energetics of the double (2H+/2e-), i.e., the first 1H+/1e- (catechol-> phenoxyl radical) and the second 1H+/1e- (phenoxyl radical-> quinone) free radical scavenging mechanisms of quercetin and its six colonic catecholic metabolites (caffeic acid, hydrocaffeic acid, homoprotocatechuic acid, protocatechuic acid, 4-methylcatechol, and catechol) were computationally studied using density functional theory, with the aim to estimate the antiradical potency of these molecules. We found that second hydrogen atom transfer (HAT) and second sequential proton loss electron transfer (SPLET) mechanisms are less energy demanding than the first ones indicating 2H+/2e- processes as inherent to catechol moiety. The Gibbs free energy change for reactions of inactivation of selected free radicals indicate that catecholic colonic metabolites constitute an efficient group of more potent scavengers than quercetin itself, able to deactivate various free radicals, under different biological conditions. They could be responsible for the health benefits associated with regular intake of flavonoid-rich diet. PMID- 27719891 TI - Flavonoid composition of orange peel and its association with antioxidant and anti-inflammatory activities. AB - Dried citrus peel derived from Citrus reticulata, also called "chenpi", possesses a complex mixture of flavonoids and has a history of traditional use to treat a variety of digestive disorders. We compared three sources of conventional chenpi from California (USA), Guangxi, Zhejiang, and two sources of "nchenpi", which contain greater nobiletin content, from Sichuan and Xinhui (China). Xinhui orange peel extract (OPE) had highest content of polymethoxylated flavones, along with greatest capacity to scavenge 2,2-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS), 2,2-diphenyl-1-pcrylhydrazyl (DPPH), and 2,2'-azobis-2-methyl propanimidamide, dihydrochloride (AAPH) radicals and nitric oxide (NO). OPE also had higher NO, inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX-2) inhibitory activity than an equivalent mixture of flavonoids (P<0.05). In conclusion, nobiletin is a good chemical marker for assessing the anti inflammatory potential of OPE from different sources. Obtaining "nchenpi" from either Sichuan or Xinhui provided potentially superior health benefits compared to conventional chenpi sources. PMID- 27719892 TI - Subcritical ethanol extraction of flavonoids from Moringa oleifera leaf and evaluation of antioxidant activity. AB - A large-scale process to extract flavonoids from Moringa oleifera leaf by subcritical ethanol was developed and HPLC-MS analysis was conducted to qualitatively identify the compounds in the extracts. To optimize the effects of process parameters on the yield of flavonoids, a Box-Behnken design combined with response surface methodology was conducted in the present work. The results indicated that the highest extraction yield of flavonoids by subcritical ethanol extraction could reach 2.60% using 70% ethanol at 126.6 degrees C for 2.05h extraction. Under the optimized conditions, flavonoids yield was substantially improved by 26.7% compared with the traditional ethanol reflux method while the extraction time was only 2h, and obvious energy saving was observed. FRAP and DPPH assays showed that the extracts had strong antioxidant and free radical scavenging activities. PMID- 27719893 TI - Lipid composition and emulsifying properties of canola lecithin from enzymatic degumming. AB - This study investigated the polar lipid composition and emulsifying properties of canola lecithin from enzymatic degumming (CLED). Phospholipase A1 was used for enzymatic degumming of crude canola oil to collect lecithin sample. Canola lecithin from water degumming (CLWD) was also collected and served as the control. The results showed that the contents of phosphatidylethanolamine (PE) (2.99%) and phosphatidylcholine (PC) (6.59%) in CLED were significantly lower than that in CLWD (PE 15.55% and PC 21.93%); while the content of lysophosphatidylcholine (LPC) (19.45%) in CLED was significantly higher than that in CLWD (3.27%). Unsaturated fatty acids accounted for a higher percentage of the total fatty acids in CLED than in CLWD. CLED promoted more stable o/w emulsions than CLWD. This study provides a better understanding of the chemical nature of CLED, and important information for utilization of CLED as o/w emulsifier. PMID- 27719894 TI - Effects of ultrasound pre-treatment on the structure of beta-conglycinin and glycinin and the antioxidant activity of their hydrolysates. AB - The effect of power, time and temperature of ultrasound on the structure of beta conglycinin (7S) and glycinin (11S), and on the antioxidant activity of their hydrolysates were investigated. All ultrasound treated 7S and 11S fractions showed an increase in the alpha-helix and beta-turn proportions, and a decrease in beta-sheet and random coil proportions. The polarity of 7S and 11S microenvironment increased after ultrasound treatment. Ultrasound treatment significantly increased the reduction capacity and iron chelating capacity of 7S and 11S hydrolysates. The degree of hydrolysis and free SH groups of 7S and 11S hydrolysates increased after ultrasound pre-treatment. The relative content of high molecular weight peptides reduced, and the relative content of low molecular weight peptides increased in ultrasound treated 7S and 11S hydrolysates. The ultrasonication exposed certain groups of 7S and 11S fractions, improved contact with enzymes, and increased the content of highly active soybean antioxidant peptides. PMID- 27719895 TI - Simultaneous determination of atropine and scopolamine in buckwheat and related products using modified QuEChERS and liquid chromatography tandem mass spectrometry. AB - A method was developed for the determination of atropine and scopolamine in buckwheat and related products. A modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) extraction procedure was evaluated. Dispersive solid phase extraction (d-SPE) was studied as clean-up step, using graphitized black carbon (GBC) and primary secondary amine (PSA). The extract was diluted with water (50:50, v/v) prior to chromatographic analysis. The method was validated and recoveries (except chia samples spiked at 10MUg/kg) ranged from 75% to 92%. Intra and inter-day precision was lower than or equal to 17%. The limit of quantification of atropine and scopolamine was 0.4 and 2MUg/kg, respectively. Eight types of samples (buckwheat, wheat, soy, buckwheat flour, buckwheat noodle, amaranth grain, chia seeds and peeled millet) were analyzed. Target compounds were not found above the detection limits of the method, but three transformation products of scopolamine (norscopine, hydroscopolamine and dihydroxyscopolamine) were putative identified in the tested samples using high resolution mass spectrometry (Exactive-Orbitrap). PMID- 27719897 TI - Determination of eight pesticides in Lycium barbarum by LC-MS/MS and dietary risk assessment. AB - A LC-MS/MS method for determination of eight pesticides (triadimefon, sulfoxaflor, flusilazole, tebuconazole, difenoconazole, amitraz, azoxystrobin, and thiophanate-methyl) in Lycium barbarum was established. The samples were extracted with acetonitrile, and then cleaned up by primary secondary amine. The extracts were diluted with 0.1% formic acid in water. The results showed that at the fortified levels of 0.01-10mg/kg, the average recoveries of these pesticides ranged from 82.1% to 96.2% with the relative standard deviations lower than 7%. The half-lives of eight pesticides were 1.3-5.0days in Lycium barbarum fruits. The pre-harvest interval of all pesticides mentioned above were investigated. Tebuconazole (14days), sulfoxaflor (14days) and flusilazole (28days) have longer pre-harvest interval than the others which have 7days. The dietary risks, assessed as hazard quotients, were far below 100%. The results showed that the eight pesticides applied to Lycium barbarum were comparably safe for the consumer. PMID- 27719896 TI - Analysis of seven salad rocket (Eruca sativa) accessions: The relationships between sensory attributes and volatile and non-volatile compounds. AB - Sensory and chemical analyses were performed on accessions of rocket (Eruca sativa) to determine phytochemical influences on sensory attributes. A trained panel was used to evaluate leaves, and chemical data were obtained for polyatomic ions, amino acids, sugars and organic acids. These chemical data (and data of glucosinolates, flavonols and headspace volatiles previously reported) were used in Principal Component Analysis (PCA) to determine variables statistically important to sensory traits. Significant differences were observed between samples for polyatomic ion and amino acid concentrations. PCA revealed strong, positive correlations between glucosinolates, isothiocyanates and sulfur compounds with bitterness, mustard, peppery, warming and initial heat mouthfeel traits. The ratio between glucosinolates and sugars inferred reduced perception of bitter aftereffects. We highlight the diversity of E. sativa accessions from a sensory and phytochemical standpoint, and the potential for breeders to create varieties that are nutritionally and sensorially superior to existing ones. PMID- 27719898 TI - Crystallization and melting properties of mixtures of milk fat stearin and omega 3 rich oils. AB - Solid milk fat stearin (S25) can be a promising oxidation retarder due to its capacity to entrap liquid oils, especially for incorporating omega-3 (omega-3) rich oils into dairy products. Thermal properties of S25/omega-3 rich oil mixtures are necessary for such application. The effects of S25 on the crystallization and melting behaviours of omega-3 rich oils, namely fish oil (FO), linseed oil (LO) and krill oil (KO), were investigated by differential scanning calorimetry (DSC). Thermograms showed that with S25 concentration increasing, transitions of FO and LO shifted to lower and largely to higher temperatures, respectively, while crystallization temperature of KO slightly decreased. Negative, positive and low values of interaction enthalpy (DeltaHint) suggested the adverse, beneficial and limited effect of S25 on the crystallization of S25/FO, S25/LO and S25/KO mixtures, respectively. LO could have the best oxidative stability upon the addition of S25 since their interactions facilitated earlier and stronger crystallization. PMID- 27719899 TI - Alkali solution extraction of rice residue protein isolates: Influence of alkali concentration on protein functional, structural properties and lysinoalanine formation. AB - This study evaluated the nutrient property and safety of the rice residue protein isolates (RRPI) product (extracted by different alkali concentrations) by exploring the protein functional, structural properties and lysinoalanine (LAL) formation. The results showed that with the rising of alkali concentration from 0.03M to 0.15M, the solubility, emulsifying and foaming properties of RRPI increased at first and then descended. When the alkali concentration was greater than 0.03M, the RRPI surface hydrophobicity decreased and the content of thiol and disulfide bond, Lys and Cys significantly reduced. By the analysis of HPLC, the content of LAL rose up from 276.08 to 15,198.07mg/kg and decreased to 1340.98mg/kg crude protein when the alkali concentration increased from 0.03 to 0.09M and until to 0.15M. These results indicated that RRPI alkaline extraction concentration above 0.03M may cause severe nutrient or safety problems of protein. PMID- 27719900 TI - Characterization of polyphenol oxidase from blueberry (Vaccinium corymbosum L.). AB - Polyphenol oxidase (PPO) was extracted and characterized from high-bush blueberries. PPO showed an optimum activity at pH 6.1-6.3 and 35 degrees C, with the enzyme showing significant activity over a wide temperature range (25-60 degrees C). Catechol was the most readily oxidized substrate followed by 4 methylcatechol, DL-DOPA, and dopamine. Blueberry PPO showed a Km of 15mM and Vmax of 2.57 DeltaA420nm/min*10-1, determined with catechol. PPO was completely inactivated in 20min at 85 degrees C, however, after 30minat 75 degrees C it showed about 10% residual activity. Thermal treatment at 55 and 65 degrees C for 30min resulted in the partial inactivation of PPO. Ascorbic acid, sodium diethyldithiocarbamic acid, L-cysteine, and sodium metabisulfite were effective inhibitors of PPO at 1.0mM. Benzoic acid and cinnamic acid series inhibitors showed relatively weak inhibition of PPO (21.8-27.6%), even at as high as 2.0mM concentration. PMID- 27719901 TI - Free fatty acids and their esters modulate isothermal crystallization of anhydrous milk fat. AB - The effect of free fatty acids with different chain lengths or unsaturation degree on anhydrous milk fat (AMF) crystallization was evaluated. The impact of esterification was also studied using three triglycerides. Melted blends containing the additives at concentrations lower than 12wt.% were quenched at 25 degrees C and isothermal crystallization was monitored by pulsed low-resolution nuclear magnetic resonance. In parallel, polarized light microscopy was used to observe the microstructure. Compounds based on long chain saturated fatty acids, i.e. palmitic, stearic, eicosanoic acids, tripalmitin and tristearin accelerated crystallization. Conversely, propanoic, hexanoic and oleic acids slowed down the process, while triacetin had no impact. Interestingly, above a critical concentration, the addition of palmitic, stearic or eicosanoic acids caused a transition from a one-step to two-step process. Gompertz model was used to fit the experimental data and to assess the influence of the molecular properties of the additives on the kinetic parameters. PMID- 27719902 TI - Gel characteristics and microstructure of fish myofibrillar protein/cassava starch composites. AB - The changes in fish myofibrillar protein/cassava starch composites in the starch fraction range from 0 to 1, with their total content maintained at 60mg/mL, were investigated in terms of textural properties, rheological behaviours, morphology, spatial distribution and protein molecular structure. The results revealed that the starch fraction of 0.5 was a critical point for the conversion of the protein matrix to starch matrix and conversion of the gel from elastic to weak. Moreover, the protein-starch synergistic effect on the storage modulus was strongest at fractions of 0.5 and 0.6, due to the formation of a semi-interpenetrating network, with more amylose from the melted starch granules interpenetrated with the protein molecules, and the absorption of water by the starch granules to concentrate the protein matrix. Additionally, no covalent interaction between the protein and starch occurred with increasing starch fraction, thus having no significant influence on the protein secondary structure. PMID- 27719904 TI - Nutritional and mineral contents of honey extracted by centrifugation and pressed processes. AB - In this study, wild honey samples extracted by two different methods (centrifugation and pressed processing) were characterized and compared based on their physicochemical, and nutritional properties, macro- and micro-mineral contents, and pollen counts. Twelve colonies of Africanized Apis mellifera were used; six honey samples were obtained by centrifugation and six by honeycomb press. All physicochemical parameters of honey samples (moisture, pH, total acidity, ash, dry matter, and qualitative absence of hydroxymethylfurfural) were within the limits established by EU legislation, and all parameters in pressed honey were superior (p<0.05). Nutritional contents (total carbohydrates, total lipids, total proteins, flavonoids, and ascorbic acid) and minerals (K, Ca, Mg, Na, Fe, Li, Zn) were also higher in pressed honey. The quantity of pollen in pressed honey samples was 5.6-fold higher than in centrifuged samples. Pressed honey, can be marked as a differentiated product with a higher mineral content and several nutritional properties. PMID- 27719903 TI - Qualitative and quantitative detection of honey adulterated with high-fructose corn syrup and maltose syrup by using near-infrared spectroscopy. AB - Near-infrared spectroscopy (NIR) was used for qualitative and quantitative detection of honey adulterated with high-fructose corn syrup (HFCS) or maltose syrup (MS). Competitive adaptive reweighted sampling (CARS) was employed to select key variables. Partial least squares linear discriminant analysis (PLS LDA) was adopted to classify the adulterated honey samples. The CARS-PLS-LDA models showed an accuracy of 86.3% (honey vs. adulterated honey with HFCS) and 96.1% (honey vs. adulterated honey with MS), respectively. PLS regression (PLSR) was used to predict the extent of adulteration in the honeys. The results showed that NIR combined with PLSR could not be used to quantify adulteration with HFCS, but could be used to quantify adulteration with MS: coefficient (Rp2) and root mean square of prediction (RMSEP) were 0.901 and 4.041 for MS-adulterated samples from different floral origins, and 0.981 and 1.786 for MS-adulterated samples from the same floral origin (Brassica spp.), respectively. PMID- 27719905 TI - Improving the extraction of Ara h 6 (a peanut allergen) from a chocolate-based matrix for immunosensing detection: Influence of time, temperature and additives. AB - The extraction of Ara h 6 (a peanut allergen) from a complex chocolate-based food matrix was optimized by testing different temperatures, extraction times, and the influence of additives (NaCl and skimmed milk powder) in a total of 36 different conditions. Analyses were carried out using an electrochemical immunosensor. Three conditions were selected since they allowed the extraction of the highest levels of Ara h 6. These extractions were performed using 2g of sample and 20ml of Tris-HNO3 (pH=8) containing: a) 0.1M NaCl and 2g of skimmed milk powder at 21 degrees C for 60min; b) 1M NaCl and 1g of skimmed milk powder at 21 degrees C for 60min; and c) 2g of skimmed milk powder at 60 degrees C for 60min. Recoveries were similar or higher than 94.7%. This work highlights the importance to adjust extraction procedures regarding the target analyte and food matrix components. PMID- 27719906 TI - The dietary biogenic amines tyramine and histamine show synergistic toxicity towards intestinal cells in culture. AB - Tyramine and histamine are the biogenic amines (BA) most commonly found at high concentrations in food; they may even appear together at toxic concentrations. The present work examines, via real-time cell analysis, whether histamine and tyramine show synergistic toxicity towards intestinal cell cultures. Employing a constant equipotency ratio, their interaction was examined via the combination index (CI) method of Chou & Talalay. Co-treatment with tyramine and histamine was associated with a stronger cytotoxic effect than was treatment with either BA or on its own. Indeed, a synergistic interaction (CI<1) was observed in the range of concentrations found in foods. The results also show that histamine, at concentrations below the legal limit, increases the cytotoxicity of tyramine at concentrations frequently reached in some foods. The synergistic cytotoxicity of tyramine and histamine should be taken into account when establishing legal limits designed to ensure consumer safety. PMID- 27719907 TI - Compositional fingerprint of soy sauces via hydrophobic surface interaction. AB - In this work, the interaction of soy sauces with hydrophobic surfaces has been analyzed. Hydrophobic self-assembled monolayers on gold or silicon dioxide were used to harvest conditioning layers from soy sauce products with varying amounts of additives. The data was compared to adsorption of soy protein and glutamic acid as common ingredients. Spectral ellipsometry revealed that all tested sauces led to the formation of thin overlayers on hydrophobic surfaces. Products with less additives yielded adlayers in the same thickness range as pure soy protein. In contrast, sauces with more ingredients create distinctly thicker films. Using water contact angle goniometry, it is shown that all adlayers render the substrate more hydrophilic. Infrared spectroscopy provided a deeper insight into the adlayer chemistry and revealed that the adlayer composition is dominated by protein rich components. X-ray reflectivity on selected films provided further insight into the density profiles within the adlayers on the molecular scale. PMID- 27719908 TI - Effect of ultrasound followed by high pressure processing on prebiotic cranberry juice. AB - This work evaluated the effect of high pressure processing (HPP) and ultrasound (US) on the quality of prebiotic cranberry juice fortified with fructo oligosaccharides (FOS). The juice was subjected to HPP for 5min (450MPa) and to ultrasonic treatment for 5min (600 and 1200W/L) followed by HPP for 5min (450MPa). Chemical analyses were carried out to identify and quantify the anthocyanins, and to quantify FOS, organic acids, instrumental color, soluble solids, pH and antioxidant capacity. Both non-thermal treatments preserved the FOS content maintaining the prebiotic property of the juice. The retention of organic acids was high (>90%) and an increase in anthocyanin content (up to 24%) was observed when ultrasound was followed by HPP. The changes in instrumental color, soluble solids content and pH were negligible. The use of HPP and ultrasound processing has been proven satisfactory to treat prebiotic cranberry juice. PMID- 27719909 TI - Identification of the geographical origins of sea cucumber (Apostichopus japonicus) in northern China by using stable isotope ratios and fatty acid profiles. AB - Geographic traceability is an important issue for food quality and safety control of seafood. In this study,delta13C and delta15N values, as well as fatty acid (FA) content of 133 samples of A. japonicus from seven sampling points in northern China Sea were determined to evaluate their applicability in the origin traceability of A. japonicus. Principal component analysis (PCA) and discriminant analysis (DA) were applied to different data sets in order to evaluate their performance in terms of classification or predictive ability. delta13C and delta15N values could effectively discriminate between different origins of A. japonicus. Significant differences in the FA compositions showed the effectiveness of FA composition as a tool for distinguishing between different origins of A. japonicus. The two technologies, combined with multivariate statistical analysis, can be promising methods to discriminate A. japonicus from different geographical areas. PMID- 27719910 TI - Stability improvement of natural food colors: Impact of amino acid and peptide addition on anthocyanin stability in model beverages. AB - Anthocyanins are prone to chemical degradation and color fading in the presence of vitamin C. The potential of three amino acids (l-phenylalanine, l-tyrosine, l tryptophan) and a polypeptide (epsilon-poly-l-lysine) in prolonging the color stability of purple carrot anthocyanins (0.025%) in model beverages (0.05% l ascorbic acid, citric acid, pH 3.0) stored at elevated temperature (40 degrees C/7 days) was examined. In the absence of amino acids or peptides, anthocyanin degraded at first-order reaction rate. Addition of amino acids or peptide (0.1%) increased the color stability of anthocyanins, with the most significant improvement observed for l-tryptophan. The average half-life of anthocyanin color increased from 2 days to 6 days with l-tryptophan addition. Fluorescence quenching measurements revealed that the l-tryptophan interacted with anthocyanins mainly through hydrogen bonding, although some hydrophobic interaction may also have been involved. Overall, this study suggests that amino acid or peptide addition may prolong the color stability of anthocyanin in beverage products. PMID- 27719911 TI - iTRAQ analysis of low-phytate mung bean sprouts treated with sodium citrate, sodium acetate and sodium tartrate. AB - The effects of sodium citrate (SC), sodium acetate (SA) and sodium tartrate (ST) spraying on mung bean germination were investigated. Exogenous SC, ST and SA treatments significantly reduced the phytic acid content and increased the antioxidant enzyme activities. In this study, an iTRAQ-based proteomic approach was employed to explore the proteomes of mung bean sprouts, and 81, 101 and 90 differentially expressed proteins were identified in 4-day-old SC-, SA- and ST treated mung bean sprouts, with 38 proteins present in all samples. Functional classification analysis showed that most of the differentially expressed proteins in mung bean sprouts subjected to the three treatments were involved in carbohydrate and energy metabolism. The inhibitory effect of the SA treatment was probably due to impairments in protein biosynthesis, whereas enhanced energy metabolism, accelerated reserve hydrolysis and protein processing were very important strategies for growth stimulation in response to ST and SC treatments. PMID- 27719912 TI - Nutrient compositions and antioxidant capacity of kiwifruit (Actinidia) and their relationship with flesh color and commercial value. AB - The nutritional quality and antioxidant capacity of China domestic kiwifruit and imported kiwifruit with different prices and the relationships of retail price among cultivars, nutritional qualities and flesh color were investigated. Results showed that cultivar was the main factor influencing nutritional quality, though the product region could also affect the cultivar characteristics to some extent. Additionally, nutritional quality and antioxidant capacity of kiwifruit had no relationship to the product region. What's more, there was no correlation among the nutrient compositions, antioxidant capacity and retail price of kiwifruit. At the same time, the flesh color was associated with greater commercial value but was not higher nutritional quality or antioxidant capacity. Thus indicates to consumers that imported kiwifruit were not all superior to local versions, and the priciest kiwifruit did not equal to the most nutritious kiwifruit, also the color kiwifruit. There still need more research to help consumers to choose kiwifruit. PMID- 27719913 TI - Investigation of caking by fat bridging in aged infant formula. AB - Three commercial infant formulas (denoted as P1, P2 and P3) were stored at 25, 45 and 60 degrees C for up to 6weeks to study the caking phenomenon caused by fat bridging. At 60 degrees C, both the surface free-fat content and the caking strength increased significantly. Analysis of the fatty acid composition of P1 showed that high-melting-point fatty acids were present on powder surface whereas low-melting-point fatty acids remained within powder particles. There was no preferential migration or retention of specific fatty acids in P2. The stearic acid content in the surface free-fat of P3 increased, largely due to a concentration gradient which contributed to the increased caking strength. The melting characteristics of surface free-fat analyzed by DSC were consistent with their fatty acid compositions analyzed by GC-MS/FID. Confocal laser scanning microscopy (CLSM) showed higher occurrence of large fat globules after 6weeks' storage.

AB - Extracts with water:ethanol (100:0, 70:30, 50:50, 30:70, 0:100) solutions from fresh (F), just dried (JD), dried and stored for one year (DS) Justicia spicigera leaves were obtained using the stirring and ultrasound techniques. Extracts were analyzed in physicochemical and antioxidant characteristics. Identification of chemical compounds by gas chromatography-mass spectroscopy (GC-MS) was also performed. 2.14+/-0.91, 5.67+/-1.70, and 8.52+/-4.97g Gallic acid equivalents/100g dry weight (d.w.) of phenolic compounds were found, in average, for F, JD, and DS J. spicigera, respectively. 2.22+/-1.31, 2.58+/-2.11, and 8.48+/-3.78g Trolox equivalents/100g d.w. were detected with the ABTS method and 0.49+/-0.33, 1.23+/-0.87, and 0.88+/-0.94g with the DPPH method for F, JD and DS J. spicigera, respectively. Eucalyptol, phytol, and azulene were identified as the main compounds. J. spicigera showed colors (green-iridescent, green-yellow, or pink of different intensities) and antioxidant characteristics depending on the solvent concentration. Extracts could be used in the food and pharmaceutical industries. PMID- 27719915 TI - Evaluation of selenium in dietary supplements using elemental speciation. AB - Selenium-enriched dietary supplements containing various selenium compounds are readily available to consumers. To ensure proper selenium intake and consumer confidence, these dietary supplements must be safe and have accurate label claims. Varying properties among selenium species requires information beyond total selenium concentration to fully evaluate health risk/benefits A LC-ICP-MS method was developed and multiple extraction methods were implemented for targeted analysis of common "seleno-amino acids" and related oxidation products, selenate, selenite, and other species relatable to the quality and/or accuracy of the labeled selenium ingredients. Ultimately, a heated water extraction was applied to recover selenium species from non-selenized yeast supplements in capsule, tablet, and liquid forms. For selenized yeast supplements, inorganic selenium was monitored as a means of assessing selenium yeast quality. A variety of commercially available selenium supplements were evaluated and discrepancies between labeled ingredients and detected species were noted. PMID- 27719916 TI - Proteomic analysis of anti-nutritional factors (ANF's) in soybean seeds as affected by environmental and genetic factors. AB - The genotype (G), environment (E), and the relationship between G and E on soybean seed anti-nutritional factors (ANF's) were examined under three different agro-climatic conditions. The field trials were conducted at Maryland, South Carolina and South Dakota using nine region specific genotypes. At each location, the nine genotypes were grown with two planting/sowing dates. Differentially expressed protein spots from the two-dimensional gel electrophoresis were analyzed using mass spectrometry. Seven ANF's corresponding to soybean agglutinin and Kunitz trypsin inhibitor were identified based on the statistical significance levels at p<0.005. The G and E conditions (planting/sowing season) influences the ANF's content. This initial study suggests that early sowing reduces the total ANF's content irrespective of genotypes and their growing locations.

AB - Two Brassicaceae (Eruca sativa, Brassica oleracea var. sabauda) were stored in air and under a modified atmosphere for several days after their expiry date and then analyzed. The polyphenol content and composition, as well as the antioxidant activity of the extracts, were assessed, compared to the fresh products. Antimicrobial properties on tester strains (Bacillus cereus, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa) and in vitro anti-proliferative activity were evaluated. The cabbage extracts exhibited antimicrobial activity mainly on the ninth day after the expiry date and retained significant inhibitory effects against colon carcinoma (CaCo-2) cells. The rocket salad extract exhibited antiproliferative but not antimicrobial activity. Overall, our results indicated that they might represent a good source of natural antioxidants with antimicrobial and anti-proliferative activity, also after their expiry date, suggesting their exploitation for the recovery of important biomolecules used in the food and health industry.

AB - By squeezing electromagnetic energy into small volumes near a metal-dielectric interface, plasmonics provide many routes to enhance and manipulate light-matter interactions, which presents new strategies for signal enhancing technologies. As an extension of the ideas of plasmonics to the terahertz (THz) range, metamaterials have shown great potential in sensing applications. In this study, terahertz time-domain spectroscopy (THz-TDS) combined with metamaterials was used to detect chlorpyrifos-methyl (CM), which is one type of the broad-spectrum organophosphorus pesticides. The results demonstrate that sensitivity is greatly improved using THz metamaterials, with the limit of detection (LOD) of CM reaching 0.204mgL-1, which is lower than the World Health Organization's provisional guideline limit for CM in vegetables (1mgL-1). The results indicated that THz spectroscopy combined with metamaterials could be a valuable method for highly sensitive THz applications, presenting a new strategy for food quality and safety control in the future.

AB - This paper explored the causes of protein precipitate formation in blanched soymilk prepared by blanching soybeans through studying the changes in composition and amount of protein particles during its thermal processing. Compared with the traditional method of preparing soymilk, blanching changed the thermal aggregation behavior of protein particles. Results showed that when blanching was applied to soybeans, beta-conglycinin (7S) was denatured in the blanched soybeans, which resulted in the fixation and aggregation of 7S prior to the grinding processing. Therefore, 7S lost its inhibitory ability on the growth of other protein aggregation, explaining the increased insoluble precipitates in the blanched soymilk. PMID- 27719920 TI - Multi-element analysis of vegetal foodstuff by means of low power total reflection X-ray fluorescence (TXRF) spectrometry. AB - In this work, an analytical methodology in combination with a low power benchtop total reflection X-ray fluorescence (TXRF) system has been developed for multi elemental analysis of vegetal materials. An easy and rapid sample preparation consisting in suspending 20mg of sample in de-ionized water showed to be the most suitable for this kind of samples. However, for comparison purposes, two digestion procedures were also applied. A set of fifteen certified reference materials and three real vegetal samples were employed for the quantitative determination of K, Ca, Mn, Fe, Cu, Zn, Br, Rb, Sr, Pb, As and Sn. All the parameters affecting sample preparation and TXRF measurements conditions were carefully evaluated. Accurate and precise results were obtained for mid-high Z elements (Mn-Sr) using internal standardization as quantification approach, while for light Z elements (K and Ca), due to absorption effects, an improvement of analytical results by external calibration was necessary. PMID- 27719921 TI - Betalains increase vitexin-2-O-xyloside cytotoxicity in CaCo-2 cancer cells. AB - Vitexin-2-O-xyloside (XVX) from Beta vulgaris var. cicla L. (BVc) seeds, betaxanthin (R1) and betacyanin (R2) fractions from Beta vulgaris var. rubra L. (BVr) roots were combined and tested for cytotoxicity in CaCo-2 colon cancer cells. XVX was the most cytotoxic molecule, but the combination of XVX with R1 and R2 significantly prolonged its cytotoxicity. Cytotoxicity was mediated by the intrinsic apoptotic pathway, as shown by an increase in Bcl2-like protein 4, cleaved Poly ADP-Ribosyl Polymerase 1 and cleaved Caspase 3 levels with a parallel decrease in anti-apoptotic protein B-cell leukemia/lymphoma 2 levels. R1 and R2, used alone or in combination, reduced oxidative stress triggered by H2O2 in CaCo-2 cells. Betalains dampened cyclooxygenase-2 and interleukin-8 mRNA expression after lipopolysaccharide induction in CaCo-2, showing an anti inflammatory action. Our results support the use of a cocktail of R1, R2 and XVX as a chemopreventive tool against colon cancer. PMID- 27719922 TI - Drug-in-cyclodextrin-in-liposomes as a carrier system for volatile essential oil components: Application to anethole. AB - A combined approach based on cyclodextrin/drug inclusion complex formation and loading into liposomes was applied to improve the effectiveness of liposome loading with essential oils. Hydroxypropyl-beta-cyclodextrin/ANE (HP-beta-CD/ANE) inclusion complexes were prepared and encapsulated into liposomes (ACL). ANE double-loaded liposomes (ACL2) were obtained with the HP-beta-CD/ANE complex in the aqueous phase and ANE in the organic phase. Liposomes were prepared from saturated (Phospholipon 90H) or unsaturated (Lipoid S100) phospholipids and characterized for size, polydispersity index, zeta potential, morphology, loading rate (LR) and photo- and storage stabilities. All liposome batches were nanometric oligolamellar-type vesicles. Compared to ANE-loaded liposomes, ACL 90H, ACL2-90H and ACL2-S100 displayed significantly increased ANE LR, with ACL2 S100 exhibiting the highest LR. All formulations provided ANE photoprotection, were physically stable after 15months of storage at 4 degrees C (with the exception of ACL2-S100), and retained more than 25% of the ANE initially present in the liposome suspensions. PMID- 27719923 TI - Immunogenic inhibition of prominent ruminal bacteria as a means to reduce lipolysis and biohydrogenation activity in vitro. AB - Lipolysis and biohydrogenation in ruminal animals promote the accumulation of saturated fatty acids in their meat and milk. Antibodies were generated against key ruminal lipase contributors Anaerovibrio lipolyticus, Butyrivibrio fibrisolvens, Propionibacterium avidum and acnes. An anti-Pseudomonas lipase antibody was generated to determine if an antibody against a purified protein would be more effective. Each bacterium was cultured and assayed without or with increasing levels of each antibody. Butyrivibrio fibrisolvens H17C also participates in biohydrogenation and therefore the antibody was tested to determine if it could effectively reduce biohydrogenation. Butyrivibrio fibrisolvens was assayed without and with the anti-B. fibrisolvens antibody and linoleic or alpha-linolenic acid. All antibodies were effective at reducing lipolysis with the anti-Pseudomonas lipase averaging a 78% reduction. The anti-B. fibrisolvens showed a tendency for a reduction (P=0.0713) in biohydrogenation products of alpha-linolenic acid. Results demonstrate that lipolysis and biohydrogenation can be immunologically inhibited in vitro. PMID- 27719924 TI - An LC-MS/MS method for multi-mycotoxin quantification in cow milk. AB - The simultaneous quantification of 15 mycotoxins in cow milk by liquid chromatography-mass spectrometry, is presented. Extraction was performed with acidified acetonitrile, followed by a cleanup step with sodium acetate. During validation limits of detection (LOD) and quantification, linearity, precision, accuracy, recovery, matrix effect, and stability were studied. LOD values were between 0.02 and 10.14ng/mL for aflatoxins M1, B1, B2, G1, G2, ochratoxins A and B, HT-2 and T-2 toxins, deepoxy-deoxynivalenol, zearalenone, sterigmatocystin and fumonisins B1, B2 and B3. Recovery values were between 82.6 and 94.4% for all the mycotoxins, except for fumonisins. The recovery values for fumonisins were between 42.1% and 64.6%. Matrix effect, between 25.5 and 96.8%, appeared for all of the mycotoxins, especially for deepoxy-deoxynivalenol, zearalenone and sterigmatocystin. The validated method achieves the quantification of those mycotoxins of major concern and mycotoxins that are not frequently studied in milk, such as fumonisins, sterigmatocystin or ochratoxin B. PMID- 27719925 TI - Extraction optimization and identification of anthocyanins from Nitraria tangutorun Bobr. seed meal and establishment of a green analytical method of anthocyanins. AB - This study aimed to extract and identify anthocyanins from Nitraria tangutorun Bobr. seed meal and establish a green analytical method of anthocyanins. Ultrasound-assisted extraction of anthocyanins from N. tangutorun seed meal was optimized using response surface methodology. Extraction at 70 degrees C for 32.73 min using 51.15% ethanol rendered an extract with 65.04mg/100g of anthocyanins and 947.39mg/100g of polyphenols. An in vitro antioxidant assay showed that the extract exhibited a potent DPPH radical-scavenging capacity. Eight anthocyanins in N. tangutorun seed meal were identified by HPLC-MS, and the main anthocyanin was cyanidin-3-O-(trans-p-coumaroyl)-diglucoside (18.17mg/100g). A green HPLC-DAD method was developed to analyse anthocyanins. A mixtures of ethanol and a 5% (v/v) formic acid aqueous solution at a 20:80 (v/v) ratio was used as the optimized mobile phase. The method was accurate, stable and reliable and could be used to investigate anthocyanins from N. tangutorun seed meal. PMID- 27719926 TI - Bioactive peptides from Atlantic salmon (Salmo salar) with angiotensin converting enzyme and dipeptidyl peptidase IV inhibitory, and antioxidant activities. AB - The pH shift method was utilised for the recovery of proteins from salmon trimmings (ST), yielding 93% (w/w) protein. ST protein (STP) hydrolysates were generated with different enzyme preparations. STP incubated with Corolase PP for 1h (STP-C1) had the most potent angiotensin converting enzyme (ACE) and dipeptidyl peptidase IV (DPP-IV) inhibitory and oxygen radical absorbance capacity (ORAC) activities. Analysis of fractions of STP-C1 using UPLC-MS/MS identified sixteen peptides/amino acids. Tyr-Pro had the highest ACE inhibitory activity (ACE IC50=5.21+/-0.94MUM). The highest DPP-IV inhibitory activity was found with the amino acid Tyr (DPP-IV IC50=75.15+/-0.84MUM). Val-Pro had the highest ORAC activity (19.45+/-2.15MUmol of TEg-1). To our knowledge, the peptides Gly-Pro-Ala-Val, Val-Cys, and Phe-Phe have not been previously identified to have the activities tested in this study. These results indicate that STP hydrolysates are potential sources of bioactive peptides. PMID- 27719927 TI - Characterization of neural network generalization in the determination of pH and anthocyanin content of wine grape in new vintages and varieties. AB - The generalization ability of hyperspectral imaging combined with neural networks (NN) in estimating pH and anthocyanin content during ripening was evaluated for vintages and varieties not employed in the NN creation. A NN, from a previously published work, trained with grape samples of Touriga Franca (TF) variety harvested in 2012 was tested with TF from 2013 and two new varieties, Touriga Nacional (TN) and Tinta Barroca (TB) from 2013. Each sample contained a small number of whole berries. The present work results suggest that, under certain conditions, it might be possible for the NN to provide for new vintages and varieties results comparable to those of the vintages and varieties employed in the NN training. For pH, the results are state-of-the-art for the new vintage and varieties tested. For anthocyanin, generalization is bad for TB from 2013 but presents state-of-the-art absolute percentage error for TF and TN from 2013. PMID- 27719928 TI - Metabolomic analyses of banana during postharvest senescence by 1H-high resolution-NMR. AB - Banana is a tropical fruit widely accepted by people over the world. Its chemical composition is critical for its organoleptic properties and nutritional value. In this work, the metabolite changes during postharvest senescence were investigated using NMR spectroscopy. The 1D and 2D NMR spectroscopic information revealed the primary and secondary metabolites in banana fruit, including organic acids, amino acids, carbohydrates and phenolics. Bananas at five senescence stages showed similar chemical profiles, but the levels of the individual compounds varied to a large extent. The principal metabolites responsible for postharvest senescence of banana were valine, alanine, aspartic acid, choline, acetate, glucose, malic acid, gallic acid and dopamine. At stage V, ethanol was present due to the conversion of glucose. Salsolinol was generated due to the conversion of dopamine. This was a characteristic marker for the postharvest senescence of banana fruit. PMID- 27719929 TI - How to predict the sugariness and hardness of melons: A near-infrared hyperspectral imaging method. AB - Hyperspectral imaging (HSI) in the near-infrared (NIR) region (900-1700nm) was used for non-intrusive quality measurements (of sweetness and texture) in melons. First, HSI data from melon samples were acquired to extract the spectral signatures. The corresponding sample sweetness and hardness values were recorded using traditional intrusive methods. Partial least squares regression (PLSR), principal component analysis (PCA), support vector machine (SVM), and artificial neural network (ANN) models were created to predict melon sweetness and hardness values from the hyperspectral data. Experimental results for the three types of melons show that PLSR produces the most accurate results. To reduce the high dimensionality of the hyperspectral data, the weighted regression coefficients of the resulting PLSR models were used to identify the most important wavelengths. On the basis of these wavelengths, each image pixel was used to visualize the sweetness and hardness in all the portions of each sample. PMID- 27719930 TI - Highly selective and sensitive determination of several antioxidants in human breast milk using high-performance liquid chromatography based on Ag(III) complex chemiluminescence detection. AB - Ascorbic acid (AA), uric acid (UA) and glutathione (GSH) are the most important water-soluble antioxidants. The concentrations of GSH and glutathione disulfide (GSSG) and their molar ratio are the indicators of oxidative stress. Little is known about the contents of UA, GSH and GSSG in human milk; a reliable and sensitive method to monitor the concentrations of the four compounds simultaneously in human milk is of critical importance. A new method for separation and quantification of these water-soluble antioxidants by HPLC coupled with Ag(III) chemiluminescence detector has been developed in this work with better recoveries. The antioxidants contents were determined in different times of lactation utilizing this method. The results show that the levels of AA, UA, GSH and GSH/GSSG of human colostrum are significantly higher than those of mature milk (P<0.05). It is concluded that colostrum contains more water-soluble antioxidants than mature milk. PMID- 27719931 TI - Antibacterial polyketides from Bacillus amyloliquefaciens associated with edible red seaweed Laurenciae papillosa. AB - Heterotrophic Bacillus amyloliquefaciens associated with edible red seaweed, Laurenciae papillosa was used to isolate antibacterial polyketide compounds. Antibacterial activity studies integrated with the outcome obtained by polyketide synthetase (pks) coding genes established that seaweed-affiliated bacterial flora had a wide-ranging antibacterial activities and potential natural product diversity, which proved that the bacterium is valuable reservoir of novel bioactive metabolites. Bioactivity-guided isolation of 3-(octahydro-9-isopropyl 2H-benzo[h]chromen-4-yl)-2-methylpropyl benzoate and methyl 8-(2-(benzoyloxy) ethyl)-hexahydro-4-((E)-pent-2-enyl)-2H-chromene-6-carboxylate of polyketide origin, with activity against human opportunistic food pathogenic microbes, have been isolated from the ethyl acetate extract of B. amyloliquefaciens. Structure activity relationship analysis revealed that hydrophobic descriptor of the polyketide compounds significantly contribute towards its antibacterial activity. Seaweed-associated microorganisms were shown to represent a potential source of antimicrobial compounds for food and health benefits. The antibacterial polyketide compounds described in the present study may find potential applications in the food industry to reduce food-borne pathogens. PMID- 27719932 TI - Sardinian Boraginaceae are new potential sources of gamma-linolenic acid. AB - The aim of this work was to establish the richness in gamma-linolenic acid (GLA, 18:3n6) and stearidonic acid (SDA, 18:4n3) of several Sardinian Boraginaceae species. To this end, seeds of selected species were collected from their natural habitats and analysed. The highest GLA contents were found in the seed oils of two endemic Borago taxa, i.e. B. morisiana (24.4 and 24.6% GLA of total fatty acids for samples from San Pietro Island and Sardinia Island, respectively), and 22.9% GLA for B. pygmaea. Both Borago species contained more GLA than B. officinalis collected in the same ecosystems. SDA was found in significant amounts in Echium plantagineum seed oil from the Lattias Mountains (15% SDA of total fatty acids). It is notable that both Borago GLA-rich species are under threat of extinction, thus revealing the importance of the preservation of the natural Sardinian ecosystems for endangered species and human health. PMID- 27719933 TI - Antiradical activity of delphinidin, pelargonidin and malvin towards hydroxyl and nitric oxide radicals: The energy requirements calculations as a prediction of the possible antiradical mechanisms. AB - Naturally occurring flavonoids, delphinidin, pelargonidin and malvin, were investigated experimentally and theoretically for their ability to scavenge hydroxyl and nitric oxide radicals. Electron spin resonance (ESR) spectroscopy was used to determine antiradical activity of the selected compounds and M05-2X/6 311+G(d,p) level of theory for the calculation of reaction enthalpies related to three possible mechanisms of free radical scavenging activity, namely HAT, SET-PT and SPLET. The results obtained show that the molecules investigated reacted with hydroxyl radical via both HAT and SPLET in the solvents investigated. These results point to HAT as implausible for the reaction with nitric oxide radical in all the solvents investigated. SET-PT also proved to be thermodynamically unfavourable for all three molecules in the solvents considered. PMID- 27719934 TI - Multi-mycotoxin stable isotope dilution LC-MS/MS method for Fusarium toxins in beer. AB - A stable isotope dilution LC-MS/MS multi-mycotoxin method was developed for 12 different Fusarium toxins including modified mycotoxins in beer (deoxynivalenol-3 glucoside, deoxynivalenol, 3-acetyldeoxynivalenol, 15-acetyl-deoxynivalenol, HT2 toxin, T2-toxin, enniatin B, B1, A1, A, beauvericin and zearalenone). As sample preparation and purification of beer a combined solid phase extraction for trichothecenes, enniatins, beauvericin and zearalenone was firstly developed. The validation of the new method gave satisfying results: intra-day and inter-day precision and recoveries were 1-5%, 2-8% and 72-117%, respectively. In total, 61 different organic and conventional beer samples from Germany and all over the world were analyzed by using the newly developed multi-mycotoxin method. In summary, deoxynivalenol, deoxynivalenol-3-glucoside, 3-acetyldeoxynivaleneol and enniatin B were quantified in rather low contents in the investigated beer samples. None of the other monitored Fusarium toxins like 15 acetyldeoxynivalenol, HT2- and T2-toxin, zearalenone, enniatin B1, A1, A or beauvericin were detectable. PMID- 27719935 TI - Phosphorylation prevents in vitro myofibrillar proteins degradation by MU calpain. AB - Myofibrillar proteins degradation contributes to meat tenderisation during post mortem ageing. Protein phosphorylation has been revealed to be associated with meat tenderness in recent years. This study was undertaken to determine the impact of myofibrillar proteins phosphorylation on the degradation susceptibility by MU-calpain. Myofibrillar proteins were first incubated with protein kinase A (PKA) or alkaline phosphatase (AP) to increase or decrease the phosphorylation level, following MU-calpain hydrolysis. Myosin heavy chain, actin, desmin and troponin T showed different levels of degradation in control, AP and PKA groups under different Ca2+ concentrations. Generally, more degradation products were detected with the increase of Ca2+ concentration. Compared to the control, the protein degradation was higher in AP-treated group and lower in PKA-treated group. This study shows that phosphorylation prevents proteolytic susceptibility of myofibrillar proteins to degradation by MU-calpain, indicating that protein phosphorylation plays an important role in meat tenderisation during post-mortem ageing. PMID- 27719936 TI - A dual antibacterial mechanism involved in membrane disruption and DNA binding of 2R,3R-dihydromyricetin from pine needles of Cedrus deodara against Staphylococcus aureus. AB - The antibacterial activity and mechanism of 2R,3R-dihydromyricetin (DMY) against Staphylococcus aureus were investigated. The minimum inhibitory concentration of DMY against S. aureus was 0.125mg/ml, and the growth inhibitory assay also revealed that DMY showed a potent antibacterial activity against S. aureus. Massive nucleotide leakage and flow cytometric analysis demonstrated that DMY disrupted the membrane integrity of S. aureus. Morphological changes and membrane hyperpolarization of S. aureus cells treated with DMY further suggested that DMY destroyed cell membrane. Meanwhile, DMY probably interacted with membrane lipids and proteins, causing a significant reduction in membrane fluidity and changes in conformation of membrane protein. Moreover, DMY could interact with S. aureus DNA through the groove binding mode. Overall, the results suggested that DMY could be applied as a candidate for the development of new food preservatives as it achieved bactericidal activity by damaging cell membrane and binding to intracellular DNA. PMID- 27719937 TI - Changes in phenolic content of commercial potato varieties through industrial processing and fresh preparation. AB - Reported content and process stability of phenolics in potato products is inconsistent. Changes in phenolic content of select varieties through fresh and industrial preparation/reconstitution were assessed. Total chlorogenic acids (CQAs) ranged from 43 to 953mg/100g dw and were more concentrated in pigmented compared to white/yellow-fleshed potatoes. Anthocyanin (ANC) content ranged from 18.6 to 22.9mg/100g dw and were mainly present in the flesh of pigmented potatoes. Retention of phenolics through commercial processing ranged from 49 to 85% for pigmented varieties and 32-55% for white/yellow. CQA levels were reduced through processing but to a greater extent in white relative to pigmented potatoes. ANCs were well retained through industrial processing of pigmented potatoes (79-129%). Levels of CQA were significantly (p<0.05) lower in some industrially versus freshly processed products but not for all products. While some differences exist, overall, industrially processed potato products compare favorably to fresh preparation in levels and recovery of phenolics. PMID- 27719938 TI - Protection of folic acid through encapsulation in mesoporous silica particles included in fruit juices. AB - Folic acid (FA) is a synthetic vitamin commonly used for food fortification. However, its vulnerability to processing and storage implies loss of efficiency, which would induce over-fortification by processors to obtain a minimum dose upon consumption. Recent studies have indicated potential adverse effects of FA overdoses, and FA protection during processing and storage could lead to more accurate fortification. In addition, sustained vitamin release after consumption would help improve its metabolism. The objective of this work was to study controlled FA delivery and stability in fruit juices to reduce potential over fortification risks by using gated mesoporous silica particles (MSPs). The obtained results indicated that FA encapsulation in MSPs significantly improved its stability and contributed to controlled release after consumption by modifying vitamin bioaccessibility. These results confirmed the suitability of MSPs as support for controlled release and protection of bioactive molecules in food matrices in different food production and storage stages. PMID- 27719939 TI - Development of a biosensor telemetry system for monitoring fermentation in craft breweries. AB - The development and applications of biosensors in the food industry has had a rapid grown due to their sensitivity, specificity and simplicity of use with respect to classical analytical methods. In this study, glucose and ethanol amperometric biosensors integrated with a wireless telemetry system were developed and used for the monitoring of top and bottom fermentations in beer wort samples. The collected data were in good agreement with those obtained by reference methods. The simplicity of construction, the low cost and the short time of analysis, combined with easy interpretation of the results, suggest that these devices could be a valuable alternative to conventional methods for monitoring fermentation processes in the food industry. PMID- 27719940 TI - Mechanisms and kinetics of tryptophan N-nitrosation in a gastro-intestinal model. AB - The reaction of nitrite with different amino acids containing secondary amino groups was tested under simulated in-vitro conditions of the digestive tract. After treatment, tryptophan was the only amino acid that exhibited specific UV absorbance of nitrosamines at 335nm, supporting the assumption that it is the main source of endogenous nitrosamines. The combined effect of pH (from 2 to 6.5) and nitrite (from 0.1 to 20mM) was analyzed and the mechanisms and kinetic laws of tryptophan N-nitrosation were determined. The model was then completed by the addition of iron and various antioxidants in concentrations reflecting different diets. The results clearly demonstrated that, in the presence of iron, large amounts of N-nitroso-tryptophan can be formed even at neutral pH, as in the intestine. Antioxidants (ascorbic acid, trolox C, beta carotene, chlorogenic acid, phytic acid and butylated-hydroxytoluene) had various impacts on the extent of N-nitrosation, depending on the iron level. PMID- 27719941 TI - Chemometric approach to develop frying stable sunflower oil blends stabilized with oleoresin rosemary and ascorbyl palmitate. AB - The frying performance of sunflower oil blends (SOBs) stabilized with oleoresin rosemary (Rosmarinus officinalis L.) (ROSM) (200-1500mg/kg) and ascorbyl palmitate (AP) (100-300mg/kg) were tested for 18hopen pan-frying. Sunflower oil with TBHQ (SOTBHQ) (200mg/kg) and without additives (SOcontrol) served as positive and negative controls, respectively. The frying stability was monitored over time by estimating the levels of conjugated dienes, total polar compounds, polymeric compounds viz., triglyceride polymers, dimers, oxidized triglyceride monomers, diglycerides and free fatty acids, and induction period based on Rancimat. Chemometric tools were used to classify the oil samples based on frying stability. Thermo-oxidative changes were reduced significantly for blends stabilized with ROSM and AP (p<0.05). Principal component analysis (PCA) and hierarchical cluster analysis (HCA) distinguished SOBs from positive controls. A formulation consisting of 1309.62 and 129.29mg/kg of ROSM and AP, respectively, was optimized using a hybrid PCA-RSM approach. PMID- 27719942 TI - Synthesis of medium-chain length capsinoids from coconut oil catalyzed by Candida rugosa lipases. AB - A commercial preparation of Candida rugosa lipases (CRL) was tested for the production of capsinoids by esterification of vanillyl alcohol (VA) with free fatty acids (FA) and coconut oil (CO) as acyl donors. Screening of FA chain length indicated that C8-C12 FA (the most common FA found in CO triglycerides) are the best acyl-donors, yielding 80-85% of their specific capsinoids. Hence, when CO, which is rich in these FA, was used as the substrate, a mixture of capsinoids (vanillyl caprylate, vanillyl decanoate and vanillyl laurate) was obtained. The findings presented here suggest that our experimental method can be applied for the enrichment of CO with capsinoids, thus giving it additional health promoting properties. PMID- 27719943 TI - Effect of yeast mannan treatments on ripening progress and modification of cell wall polysaccharides in tomato fruit. AB - Yeast mannan treatments effectively delayed colour change and firmness decline and inhibited ethylene production in two cultivars of tomato fruit during storage. The yeast mannan treatment maintained the integrity of tomato pericarp cell wall architecture and suppressed the modification of water-soluble and insoluble pectic polysaccharides in the cell wall. A decrease in the neutral sugars, including d-galactose, l-arabinose and l-rhamnose, in water-insoluble pectin and an increase in these sugars in water-soluble pectin were inhibited by yeast mannan. The contents of d-xylose and d-mannose in the hemicellulose fraction were significantly higher in the yeast mannan-treated fruit after storage. The activities of several cell wall-modifying enzymes, including pectinmethylesterase, polygalacturonase and beta-galactosidase, were suppressed in fruit treated with yeast mannan during storage. Overall, the yeast mannan induced delay in the ripening progress of tomato fruit might occur via the strong suppression of ethylene synthesis, causing inhibition of solubilization and depolymerization of cell wall polysaccharides. PMID- 27719944 TI - Development, validation and application of an UFLC-DAD-ESI-MS method for determination of carbonyl compounds in soybean oil during continuous heating. AB - A method was developed for the extraction and UFLC-DAD-ESI-MS analysis of carbonyl compounds (CCs) in oils heated to 180 degrees C. Different parameters were evaluated, and the best results were 1.5ml of acetonitrile as the extraction solvent, manual stirring for 3min and 30min of sonication time. The method was validated using soybean oil samples spiked with CCs at concentration levels ranging from 0.2 to 10.0MUg.mL-1. The average recoveries in the lowest concentration level ranged from 70.7% to 85.0%. Detection limits ranged from 0.03 to 0.1MUg.mL-1, and the quantification limit was 0.2MUg.mL-1 for all compounds. When the method was applied to samples of heated oil, the CCs identified were 4 hydroxy-2-nonenal, 2,4-decadienal, 2,4-heptadienal, 4-hydroxy -2-hexenal, acrolein, 2-heptenal, 2-octenal, 4,5-epoxy-2-decadal, 2-decenal, and 2-undecenal, with the first three mentioned presenting the highest mean concentrations after heating, specifically 36.9, 34.8 and 22.6MUg.g-1 of oil, respectively. PMID- 27719945 TI - Ultrastructural deposition forms and bioaccessibility of carotenoids and carotenoid esters from goji berries (Lycium barbarum L.). AB - Goji berries (Lycium barbarum L.) have been known to contain strikingly high levels of zeaxanthin, while the physical deposition form and bioaccessibility of the latter was yet unknown. In the present study, we associated ripening-induced modifications in the profile of carotenoids with fundamental changes of the deposition state of carotenoids in goji berries. Unripe fruit contained common chloroplast-specific carotenoids being protein-bound within chloroplastidal thylakoids. The subsequent ripening-induced transformation of chloroplasts to tubular chromoplasts was accompanied by an accumulation of up to 36mg/100g FW zeaxanthin dipalmitate and further minor xanthophyll esters, prevailing in a presumably liquid-crystalline state within the nano-scaled chromoplast tubules. The in vitro digestion unraveled the enhanced liberation and bioaccessibility of zeaxanthin from these tubular aggregates in goji berries as compared to protein complexed lutein from spinach. Goji berries therefore might represent a more potent source of macular pigments than green leafy vegetables like spinach. PMID- 27719946 TI - Bacterial community succession and metabolite changes during doubanjiang-meju fermentation, a Chinese traditional fermented broad bean (Vicia faba L.) paste. AB - Doubanjiang-meju, a major ingredient of Chinese fermented food for several centuries, is produced using broad bean, wheat flour and salt. In this study, we investigated prokaryotic community succession and metabolite changes using high throughput sequencing and 1H-NMR methods. After 35 days, bacterial communities, except Lactobacillus and Acinetobacter, were relatively stable until the end of fermentation, and consisted predominantly of the genera Tetragenococcus, Lactobacillus, Staphylococcus, Acinetobacter, Pseudomonas and Streptococcus. Glucose, arabinose, fructose and mannitol were identified as major sugars, lactate and acetate as major organic acids, and amino acids as the major nitrogen compounds present in doubanjiang-meju. Correlation analysis revealed important links between bacterial populations and metabolites, e.g., Pseudomonas was significantly correlated with 10 nitrogenous metabolites, while Streptococcus was significantly correlated with six carbonic metabolite and eight nitrogenous metabolites. These results not only revealed bacterial succession and dynamic changes in metabolites as well as pH and color, but also elucidated their relationships during the doubanjiang-meju fermentation.

AB - Supervised principal component regression (SPCR) analysis was adopted to establish the evaluation model of peanut protein solubility. Sixty-six peanut varieties were analysed in the present study. Results showed there was intimate correlation between protein solubility and other indexes. At 0.05 level, these 11 indexes, namely crude fat, crude protein, total sugar, cystine, arginine, conarachin I, 37.5kDa, 23.5kDa, 15.5kDa, protein extraction rate, and kernel ratio, were correlated with protein solubility and were extracted to for establishing the SPCR model. At 0.01 level, a simper model was built between the four indexes (crude protein, cystine, conarachin I, and 15.5kDa) and protein solubility. Verification results showed that the coefficients between theoretical and experimental values were 0.815 (p<0.05) and 0.699 (p<0.01), respectively, which indicated both models can forecast the protein solubility effectively. The application of models was more convenient and efficient than traditional determination method.

AB - Surface-enhanced Raman scattering (SERS) imaging coupling with multivariate analysis in spectral region of 200 to 1800cm-1 was developed to quantify and visualize thiophanate-methyl (TM) and its metabolite carbendazim residues in red bell pepper (Capsicum annuum L.). Least squares support vector machines (LS-SVM) and support vector machines (SVM) models based on seven optimized characteristic peaks that showed SERS effects of TM and its metabolite carbendazim residues were employed to establish prediction models. SERS spectra with first derivative (1st) and second derivative (2nd) method were subsequently compared and the optimized model of 1st-LS-SVM acquired showed the best performance (RPD=6.08, R2P=0.986 and RMSEP=0.473). The results demonstrated that SERS imaging with multivariate analysis had the potential for rapid determination and visualization of the trace TM and its metabolite carbendazim residues in complex food matrices. PMID- 27719949 TI - Physicochemical properties of maca starch. AB - Maca (Lepidium meyenii Walpers) is gaining research attention due to its unique bioactive properties. Starch is a major component of maca roots, thus representing a novel starch source. In this study, the properties of three maca starches (yellow, purple and black) were compared with commercially maize, cassava, and potato starches. The starch granule sizes ranged from 9.0 to 9.6MUm, and the granules were irregularly oval. All the maca starches presented B-type X ray diffraction patterns, with the relative degree of crystallinity ranging from 22.2 to 24.3%. The apparent amylose contents ranged from 21.0 to 21.3%. The onset gelatinization temperatures ranged from 47.1 to 47.5 degrees C as indicated by differential scanning calorimetry. Significant differences were observed in the pasting properties and textural parameters among all of the studied starches. These characteristics suggest the utility of native maca starch in products subjected to low temperatures during food processing and other industrial applications. PMID- 27719950 TI - Synergistic effects of light quality, carbon dioxide and nutrients on metabolite compositions of head lettuce under artificial growth conditions mimicking a plant factory. AB - Carbon dioxide (CO2), nutrient supply, and light quality are amongst the major controlling factors to improve the biomass production and nutritional outputs in plant factory. The present study employed CE-MS to investigate the effects of high CO2, nutrient formulation, and LED on the accumulation of primary metabolites in head lettuce. Results suggested that high CO2 (1000ppm) and nutrient supply enhanced both the biomass and some amino acids. Hierarchical clustering analysis was used to evaluate effects of red LED in combination with high CO2 and Hoagland's formulation; distinctive cluster formation contained 14 amino acids (mostly branched-chain and aromatic amino acids, histidine and arginine). Thus, simultaneous treatments of monochromatic LED, high CO2 and nutrient formulation improved the amino acids accumulation, and likely reduced the inorganic nitrogen sources in planta. PMID- 27719952 TI - LED Blue Light-induced changes in phenolics and ethylene in citrus fruit: Implication in elicited resistance against Penicillium digitatum infection. AB - The objective was to investigate whether LED Blue Light (LBL) induces changes in phenolics and ethylene production of sweet oranges, and whether they participate in LBL-elicited resistance against the most important postharvest pathogen (Penicillium digitatum) of citrus fruit. The expression of relevant genes of the phenylpropanoid and ethylene biosynthetic pathways during elicitation of resistance was also determined. Different LBL (wavelength 450nm) quantum fluxes were used within the 60-630MUmolm-2s-1 range. The HPLC analysis showed that the most relevant increase in phenylpropanoids occurred in scoparone, which markedly increased 3days after exposing fruits to a very high quantum flux (630MUmolm-2s 1) for 18h. However, phenylpropanoids, including scoparone, were not critical factors in LBL-induced resistance. The genes involved in ethylene biosynthesis were differentially regulated by LBL. Ethylene is not involved in elicited resistance, although high LBL levels increased ethylene production in only 1h. PMID- 27719951 TI - Triacylglycerol compositions of sunflower, corn and soybean oils examined with supercritical CO2 ultra-performance convergence chromatography combined with quadrupole time-of-flight mass spectrometry. AB - A supercritical CO2 ultra-performance convergence chromatography (UPC2) system was utilized with a quadrupole time-of-flight mass spectrometry (Q-TOF MS) to examine the triacylglycerol compositions of sunflower, corn and soybean oils. UPC2 provided an excellent resolution and separation for the triacylglycerols, while the high performance Q-TOF MS system was able to provide the molecular weight and fragment ions information for triacylglycerol compound characterization. A total of 33 triacylglycerols were identified based on their elementary compositions and MS2 fragment ion profiles, and their levels in the three oils were estimated. The combination of UPC2 and Q-TOF MS may determine triacylglycerol compositions for oils and fats, and provide sn-position information for fatty acids, which may be important for food nutritional value and stability. PMID- 27719953 TI - Protein precipitating capacity and antioxidant activity of Turkish Tombul hazelnut phenolic extract and its fractions. AB - Natural (raw) hazelnut was extracted with 80% (v/v) acetone to obtain crude phenolic extract that was then fractionated for elution of low-molecular weight (LMW) and high-molecular weight (HMW) fractions. LMW fraction was further purified (LWM-FP) to remove sugars and organic acids. The crude extract and its fractions were determined by measuring their protein precipitating capacity (PPC) using two different proteins [bovine serum albumin (BSA) and gelatin], molecular weights, total phenolics, condensed tannins, and various antioxidant activities. Significant differences (p<0.05) existed in the contents of total phenolics, condensed tannins, antioxidant activities, and PPC among the crude extract and fractions, albeit to different extends. BSA and gelatin was effectively precipitated by HMW fraction. HMW fraction had the highest total phenolics, condensed tannins, and antioxidant activities, followed by crude extract, LWM-FP, and LMW, respectively. The present study suggests that HMW fraction could be utilised as a source of polyphenols for the food industry. PMID- 27719954 TI - Cytoprotective effect of seaweeds with high antioxidant activity from the Peniche coast (Portugal). AB - Screening of antioxidant potential of dichloromethane and methanolic extracts of twenty-seven seaweeds from the Peniche coast was performed by: total phenolic contents (TPC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity and oxygen radical absorbance capacity (ORAC). Seaweeds revealing the highest antioxidant activity were screened for cytoprotective potential in MCF-7 cells, including the mitochondrial membrane potential analysis and the caspase-9 activity. High correlation was found between TPC of seaweed extracts and their scavenging capacity on DPPH and peroxyl radicals. The highest antioxidant activity was displayed by the methanolic fraction of brown seaweeds belonging to Fucales, however Ulva compressa presented the highest cytoprotective effect by blunting the apoptosis process. These results suggest that high antioxidant activity may not be directly related with high cytoprotective potential. Thus, seaweeds reveal to be a promising source of compounds with potential against oxidative stress.

AB - We present a standardized, straightforward and efficient approach applicable in routine analysis of flavonoids combining sensitive NMR and HPLC experiments. The determination of the relative configuration of sugar moieties usually requires the acquisition of 13C NMR shift values. We use a combination of HPLC and sensitive NMR experiments (1D-proton, 2D-HSQC) for the unique identification of known flavones, flavanones, flavonols and their glycosides. Owing to their broad range of polarity, we developed HPLC and UHPLC methods (H2O/MeOH/MeCN/HCOOH) which we applied and validated by analyzing 46 common flavones and flavanones and exemplified for four plant extracts. A searchable data base is provided with full data comprising complete proton and carbon resonance assignments, expansions of HSQC-spectra, HPLC parameters (retention time, relative retention factor), UV/Vis and mass spectral data of all compounds, which enables a rapid identification and routine analysis of flavones and flavanones from plant extracts and other products in nutrition and food chemistry.

AB - Worldwide, barley is the main source of carbohydrate in the brewing process. However, corn is often used as an adjunct to improve and accelerate the fermentation process. Considering that, these two substrates are susceptible to fungal contamination as well as mycotoxins. The objective of the current study is to determine the incidence of the mycotoxins deoxynivalenol (DON) and fumonisin B1 (FB1) in industrial beers. The method applied for mycotoxin analyses included high performance liquid chromatography. The mean levels for recovery experiments were 89.6% for DON and 93.3% for FB1. DON was not detected in any of the analyzed samples whereas FB1 was found in 49% of the 114 samples. The current survey demonstrated levels of FB1 contamination in industrial beer, possibly due to the addition of contaminated adjuncts. It is necessary to establish maximum levels of mycotoxins in beer in Brazil and other countries in order to reduce health risks.

AB - This work aims at evaluating the main nutrients (proximate, minerals), their contribution for Dietary Reference Values in Italian population, and the antioxidant properties of some popular dishes prepared in a dedicated lab kitchen: spaghetti alle vongole, pomodori al riso, gateau di patate, carciofi alla romana, pan di Spagna. Results showed that nutrient contents and energy value varied extensively because of the variety and the nature of ingredients in the analyzed dishes, and thus defined different daily nutrient intakes and their association with health effects. A serving portion of either spaghetti alle vongole or carciofi alla romana showed to contribute to the daily nutritional recommendations respectively, with an appreciable percentage of available carbohydrates (30-22%) and a considerable content of dietary fibre (91%). Gateau di patate was particularly rich in calcium (343mg), both contributing 34% of the recommended intake, in addition to appreciable content of phosphorus and zinc. With regards to spaghetti alle vongole, pomodori al riso, gateau di patate and pan di Spagna, extractable polyphenols contributed less than 15% to total antioxidant activity, and hydrolysable polyphenols give a major contribution; carciofi alla romana showed an inverse trend. Findings provide an important contribution to the update of Italian Food Composition Databases. PMID- 27719960 TI - Rosmarinus eriocalyx: An alternative to Rosmarinus officinalis as a source of antioxidant compounds. AB - Rosmarinus eriocalyx is an aromatic evergreen bush endemic to Algeria where it is used as a condiment to flavour soups and meat and as a traditional remedy. In the present work we have analyzed for the first time the phenolic composition of polar extracts obtained from stems, leaves and flowers of R. eriocalyx by HPLC, and determined the antioxidant and antimicrobial effects by DPPH, ABTS, FRAP, ORAC and agar disc diffusion methods, respectively. Results showed that ethanolic extracts of leaves and flowers are a rich source of phenolic compounds, mainly rosmarinic acid, carnosic acid and carnosol that are the main responsible for the noteworthy antioxidant activity observed in the assays. This study showed that R. eriocalyx might be a spice to be included in the European food additive list and used as a preservative agent besides R. officinalis. PMID- 27719961 TI - Establishing the relative importance of damaged starch and fructan as sources of fermentable sugars in wheat flour and whole meal bread dough fermentations. AB - It is generally believed that maltose drives yeast-mediated bread dough fermentation. The relative importance of fructose and glucose, released from wheat fructan and sucrose by invertase, compared to maltose is, however, not documented. This is surprising given the preference of yeast for glucose and fructose over maltose. This study revealed that, after 2h fermentation of wheat flour dough, about 44% of the sugars consumed were generated by invertase mediated degradation of fructan, raffinose and sucrose. The other 56% were generated by amylases. In whole meal dough, 70% of the sugars consumed were released by invertase activity. Invertase-mediated sugar release seems to be crucial during the first hour of fermentation, while amylase-mediated sugar release was predominant in the later stages of fermentation, which explains why higher amylolytic activity prolonged the productive fermentation time only. These results illustrate the importance of wheat fructan and sucrose content and their degradation for dough fermentations. PMID- 27719962 TI - Selective enzymatic hydrolysis of chlorogenic acid lactones in a model system and in a coffee extract. Application to reduction of coffee bitterness. AB - Chlorogenic acid lactones have been identified as key contributors to coffee bitterness. These compounds are formed during roasting by dehydration and cyclization of their precursors, the chlorogenic acids (CGAs). In the present study, we investigated an approach to decompose these lactones in a selective way without affecting the positive coffee attributes developed during roasting. A model system composed of (3-caffeoylquinic acid lactone (3-CQAL), 4- caffeoyl quinic acid lactone (4-CQAL), and 4-feruloylquinic acid lactone (4-FQAL)) was used for the screening of enzymes before treatment of the coffee extracts. Hog liver esterase (HLE) hydrolyzed chlorogenic acid lactones (CQALs, FQALs) selectively, while chlorogenate esterase hydrolyzed all chlorogenic acids (CQAs, FQAs) and their corresponding lactones (CQALs, FQALs) in a non-selective way. Enzymatically treated coffee samples were evaluated for their bitterness by a trained sensory panel and were found significantly less bitter than the untreated samples.

AB - Over the last two decades, separation, identification and measurement of the total and individual content of phenolic compounds has been widely investigated. Recently, the presence of a wide range of phenolic compounds in oil-bearing plants has been shown to contribute to their therapeutic properties, including anti-cancer, anti-viral, anti-oxidant, hypoglycemic, hypo-lipidemic, and anti inflammatory activities. Phenolics in oil-bearing plants are now recognized as important minor food components due to several organoleptic and health properties, and they are used as food or sources of food ingredients. Variations in the content of phenolics in oil-bearing plants have largely been attributed to several factors, including the cultivation, time of harvest and soil types. A number of authors have suggested that the presence phenolics in extracted proteins, carbohydrates and oils may contribute to objectionable off flavors The objective of this study was to review the distribution, identification and occurrence of free and bound phenolic compounds in oil-bearing plants.

A special emphasis on Ginkgo biloba due to the controversy about its use and the approval by the European Medicines Agency is made. PMID- 27719969 TI - [Inflammation and oxidation: predictive and/or causative factors]. AB - Brain ageing leads to a series of changes that reduce the processes of adaptation and response. These transformations can end in cognitive impairment and/or dementia. Although the cause of these changes is diverse, inflammation and oxidative stress explain some of the pathophysiological mechanisms of these anomalies of brain functioning. Neuroinflammation triggers neuronal injury through the presence of inflammatory cytokines and the activation of microglia through membrane receptors and nuclear activation factors. This neuroinflammatory phenomenon also affects neuron plasticity, altering the genesis and maintenance of long-term potentiation, leading to impairment of hippocampus-dependent memory. Oxidative stress and the production of free oxygen radicals also cause toxic effects in aged brains, largely due to lipid peroxidation and DNA damage. The identification of the molecular mechanisms involved in the pathogenesis of these events could shed new light on possible therapeutic targets and offer strategies for the prevention of diseases related to brain ageing, cognitive impairment and dementia. PMID- 27719970 TI - [Neurophysiology and ageing. Definition and pathophysiological foundations of cognitive impairment]. AB - Brain ageing is produced by various morphological, biochemical, metabolic and circulatory changes, which are reflected in functional changes, whose impact depends on the presence or absence of cognitive impairment. Because of brain plasticity, together with redundancy of the distinct cerebral circuits, age- related deterioration of the brain at various levels does not always translate into loss of brain function. However, when the damage exceeds certain thresholds, there is age-related cognitive impairment, which increases the risk of developing various neurodegenerative diseases such as Alzheimer disease. Genetics, together with lifestyle, diet, and environmental factors, etc, can trigger the development of these diseases, which provoke cognitive impairment. This article discusses the most important age-related changes in the brain, as well as the pathophysiological foundations of cognitive impairment. PMID- 27719971 TI - [Prognosis and progression of cognitive impairment. Preventive measures]. AB - Because of the substantial increase in population ageing, age-related processes, such as dementia and Alzheimer disease (AD), are becoming highly prevalent. The course of this disease, including preprodromic phases, lasts at least 20 years. The presence of comorbidities, especially those of vascular origin, can trigger and aggravate disease progression. On the other hand, cognitive reserve, the absence or control of comorbid factors and healthy lifestyles can protect or modify -in the sense of slow down- disease progression. Knowledge of the phases of AD and their functional impact on affected individuals helps to identify the average prognosis and, in particular, to establish and predict care plans based on the individual's needs.

This figure is set to double by 2030, with 66 million patients, and by 2050 there will be 116 million affected persons. Dementia has an economic impact on individuals and health services and affects the global economy. It is important to evaluate costs to plan social services and healthcare and to provide information on the cost effectiveness of treatments. The economic cost of dementia was around 604 billion dollars in 2010 and estimates are obviously set to rise. PMID- 27719973 TI - Imaging of Pulmonary Manifestations of Connective Tissue Diseases.

Common CTDs with lung manifestations are rheumatoid arthritis, scleroderma or systemic sclerosis, Sjogren syndrome, polymyositis/dermatomyositis, systemic lupus erythematosis, mixed connective tissue disease, and undifferentiated connective tissue disease. The most common histopathologic patterns of CTD related interstitial lung disease are nonspecific interstitial pneumonia, usual interstitial pneumonia, organizing pneumonia, and lymphoid interstitial pneumonia. Drug treatment of CTDs can cause complications, including opportunistic infection. PMID- 27719974 TI - Imaging of Hypersensitivity Pneumonitis. AB - The management of hypersensitivity pneumonitis (HP) depends on early identification of the disease process, which is complicated by its nonspecific clinical presentation in addition to variable and diverse laboratory and radiologic findings. HP is the result of exposure and sensitization to myriad aerosolized antigens. HP develops in the minority of antigenic exposures, and conversely has been documented in patients with no identifiable exposure, complicating the diagnostic algorithm significantly. Prompt diagnosis and early intervention are critical in slowing the progression of irreversible parenchymal damage, and additionally in preserving the quality of life of affected patients.

AB - Childhood interstitial lung disease represents a rare and heterogeneous group of diseases that can result in significant morbidity and mortality, some leading to death during infancy. CT is the imaging test of choice. Although many CT findings are nonspecific and a definitive diagnosis usually cannot be reached by CT alone, the interpreting radiologist is instrumental in defining disease extent and refining the diagnosis. Chest CTs are of key importance in guiding site selection for lung biopsy and for following disease progression and response to treatment. Thus, from the radiologist's perspective, ensuring maximal quality of CT imaging and interpretation is paramount. PMID- 27719977 TI - Imaging of Occupational Lung Disease. AB - Occupational lung diseases span a variety of pulmonary disorders caused by inhalation of dusts or chemical antigens in a vocational setting. Included in these are the classic mineral pneumoconioses of silicosis, coal worker's pneumoconiosis, and asbestos-related diseases as well as many immune-mediated and airway-centric diseases, and new and emerging disorders. Although some of these have characteristic imaging appearances, a multidisciplinary approach with focus on occupational exposure history is essential to proper diagnosis. PMID- 27719978 TI - Pulmonary Vasculitis: Spectrum of Imaging Appearances. AB - Pulmonary vasculitis is a relatively uncommon disorder, usually manifesting as part of systemic vasculitis. Imaging, specifically computed tomography, is often performed in the initial diagnostic workup. Although the findings in vasculitis can be nonspecific, they can provide important clues in the diagnosis, and guide the clinical team toward the right diagnosis. Radiologists must have knowledge of common and uncommon imaging findings in various vasculitides. Also, radiologists should be able to integrate the clinical presentation and laboratory test findings together with imaging features, so as to provide a meaningful differential diagnosis. PMID- 27719979 TI - Imaging of Acute Lung Injury. AB - Acute lung injury (ALI) is the clinical syndrome associated with histopathologic diffuse alveolar damage. It is a common cause of acute respiratory symptoms and admission to the intensive care unit. Diagnosis of ALI is typically based on clinical and radiographic criteria; however, because these criteria can be nonspecific, diagnostic uncertainty is common. A multidisciplinary approach that synthesizes clinical, imaging, and pathologic data can ensure an accurate diagnosis. Radiologists must be aware of the radiographic and computed tomographic findings of ALI and its mimics. This article discusses the multidisciplinary diagnosis of ALI from the perspective of the imager. PMID- 27719980 TI - Imaging of Pulmonary Hypertension. AB - Multimodality, noninvasive imaging is increasingly used in the identification and management of pulmonary hypertension (PH). Chest radiography, ventilation perfusion scintigraphy, and Doppler echocardiography are frequently the initial studies used to evaluate patients suspected of having PH. However, their ability to evaluate the right ventricle (RV) and pulmonary vasculature is limited. Computed tomography (CT) and magnetic resonance (MR) imaging are increasingly used to identify causes of PH and assess the effect of PH on RV function. This article describes the noninvasive imaging techniques and findings, particularly CT and MR imaging, used in the diagnosis and management of suspected or known PH. PMID- 27719981 TI - Imaging of Eosinophilic Lung Diseases.

Many of these entities can be idiopathic or are secondary to parasitic infection, exposure to drugs, toxins, or radiation. These diseases exhibit a wide range of imaging findings, including consolidation, ground-glass opacities, nodules, and masses. Diagnoses often require bronchoalveolar lavage and/or biopsy to confirm respiratory eosinophilia and to exclude other entities, such as infection or malignancy. Treatment entails administration of corticosteroids, removal of inciting agents, and treatment of underlying infection. PMID- 27719982 TI - Imaging of Small Airways Diseases. AB - Small airways disease, or bronchiolitis, encompasses many conditions that result in bronchiolar inflammation and/or fibrosis. Bronchioles are distal airways within secondary pulmonary lobules that are only visible on imaging when abnormal. High-resolution computed tomography plays an important role in diagnosing small airways disease. The predominant direct high-resolution computed tomography sign of bronchiolitis includes centrilobular nodules, whereas air trapping is the main indirect finding. This article reviews bronchiolar anatomy, discusses the differential diagnosis for cellular and constrictive bronchiolitis with a focus on key imaging features, and discusses how to distinguish important mimics.

PMID- 27719987 TI - Childhood Vaccination: Implications for Global and Domestic Public Health. AB - The role of vaccination in the control and prevention of endemic and emerging diseases cannot be overemphasized. Induction of host protective immunity may be the most powerful tool and effective strategy in preventing the spread of potentially fatal disease and emerging illnesses, in particular in susceptible immunologically naive hosts. The strategy for vaccination programs is engrained in population studies recognizing benefit for the health and economic welfare of at-risk indigenous populations. Worldwide collaboration is a necessary aspect of vaccine-preventable diseases recognizing that even a small number of wild-type cases of an eradicated disease in one region presents opportunities for re emergence of the disease in geographically remote areas.

Zika is transmitted by different species of Aedes mosquitoes. Nonhuman primates and possibly rodents play a role as reservoirs. Direct interhuman transmission has also been reported. Human cases have been reported in Africa and Asia, Easter Island, the insular Pacific region, and Brazil. Its clinical profile is that of a dengue-like febrile illness, but recently associated Guillain-Barre syndrome and microcephaly have appeared. There is neither a vaccine nor prophylactic medications available to prevent Zika virus infection. PMID- 27719989 TI - Assessing the Public's Health.

PMID- 27719992 TI - Health Care in India. AB - Although a stated right for all Indians, equal access to health care in India is impeded by socioeconomic barriers. With its 3-tier system of public health care centers in villages, district hospitals, and tertiary care hospitals, government expenditure in India is inordinately low, with a disproportionate emphasis on private health spending. Accordingly, the poorest receive a minority of the available subsidies, whereas the richest obtain more than a third, fostering a divide in health care infrastructure across the rich and poor in urban and rural settings. This paradigm has implications for domestic Indian public health and global public health. PMID- 27719993 TI - Health Care in China. AB - China has recently emerged as an important global partner. However, like other developing nations, China has experienced dramatic demographic and epidemiologic changes in the past few decades. Population discontent with the health care system has led to major reforms. China's distinctive health care system, including its unique history, vast infrastructure, the speed of health reform, and economic capacity to make important advances in health care, nonetheless, has incomplete insurance coverage for urban and rural dwellers, uneven access, mixed quality of health care, increasing costs, and risk of catastrophic health expenditures.

With more health-insured whites than blacks and the proportion of gross national product spent on health care slowly increasing, two-thirds of health expenditures have been consumed by the private sector at a time when the cost of health insurance has risen to more than 3 times the rate of the consumer price index. PMID- 27719995 TI - Research Methods in Epidemiology. AB - Epidemiology is the study of the distribution and determinants of health-related states and in specified populations and the application to control health problems. Classified as either descriptive or analytical, a variety of epidemiologic approaches can be used to allow assessment of hypothesized risk factor exposure with disease outcomes. This article reviews salient aspects of epidemiologic research methods that are used repeatedly in articles in this volume on public health, neuroepidemiology, and health systems. PMID- 27719996 TI - The Epidemiology of Global Epilepsy. AB - The International League Against Epilepsy defines epilepsy as at least 2 unprovoked seizures more than 24 hours apart. It is a wide-reaching and complex illness affecting more than 70 million people worldwide and can take on a variety of forms, patterns, and severities. Geographic differences in the illness are often related to its etiology. A host of endemic illnesses and parasitic infections can lead to epilepsy syndromes. Management varies by region due to the availability of diagnostic modalities and medications. Treatment gaps in epilepsy care often are related to social and cultural factors that must also be understood. PMID- 27719997 TI - Epidemiology of Migraine. AB - Headache disorders cause significant disability. The public and most health professionals tend to perceive migraine as a minor or trivial complaint. In the past decade, important epidemiologic studies enjoining extensive surveys, pathophysiologic and genetic insights, and revised headache classification paradigms have produced clear evidence of the public health importance of headache disorders. The Global Campaign to reduce the burden of headache worldwide known as "Lifting the Burden" was launched in 2004 by the World Health Organization, the International Headache Society, the World Headache Alliance, and the European Headache Federation. This paper reviews salient progress in the neuroepidemiology of migraine headaches. PMID- 27719998 TI - I-Cubed (Infection, Immunity, and Inflammation) and the Human Microbiome. AB - Medical science is just now realizing the full importance of the microbial world. Thanks to developments such as low-cost high-throughput sequencing of microbial communities comprising the human microbiome, the identity and function of unculturable microbes are being unveiled. Public health officials and neuroepidemiology researchers will be called on to guide the understanding of I Cubed illnesses and the implications of the human microbiome for communicable and noncommunicable diseases, as the natural history is appreciated and the responsiveness of given medical and neurologic disorders to a variety of medical approaches, including strong antibiotics and immune-modulatory therapy is established. PMID- 27719999 TI - Epidemiology of Lyme Neuroborreliosis. AB - Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected blacklegged ticks. According to the Centers for Disease Control and Prevention, it is the most commonly reported vector-borne illness and the fifth most common disease in the National Notifiable Diseases Surveillance System. If left untreated, infection disseminates to the nervous system. The nonhuman primate model of Lyme disease of the nervous system, or Lyme neuroborreliosis, accurately mimics the aspects of the human illness. There is general recognition for the potential of infectious-related autoimmune inflammatory processes contributing to disease progression and clinical manifestations. PMID- 27720000 TI - Epidemiology of Neurovasculitis. AB - The epidemiology of vasculitis has witnessed extraordinary advances in the past decade influenced by the worldwide increased recognition and accurate classification and diagnosis of the vasculitides, and insights brought by genome wide association studies and other genetic investigations that contribute to the understanding of the heritable factors of some of the disorders. This article reviews the current knowledge of the epidemiology of vasculitides in different global regions. PMID- 27720001 TI - Epidemiology of Multiple Sclerosis. AB - The epidemiology of multiple sclerosis (MS) includes a consideration of genetic and environmental factors. Comparative studies of different populations have revealed prevalence and incidence rates that vary with geography and ethnicity. With a prevalence ranging from 2 per 100,000 in Japan to greater than 100 per 100,000 in Northern Europe and North America, the burden of MS is similarly unevenly influenced by longevity and comorbid disorders. Well-powered genome-wide association studies have investigated the genetic substrate of MS, providing insight into autoimmune mechanisms involved in the etiopathogenesis of MS and elucidating possible avenues of biological treatment. PMID- 27720003 TI - Epidemiology of Parkinson Disease. AB - Parkinson disease (PD) is a common progressive neurodegenerative condition, causing both motor and non motor symptoms. Motor symptoms include stiffness, slowness, rest tremor and poor postural reflexes, whereas nonmotor symptoms include abnormalities of mood, cognition, sleep and autonomic function. Affected patients show cell loss in the substantia nigra pars compacta, and accumulation of aggregated alpha-synuclein into intracellular structures called Lewy bodies, within specific brain regions. The main known non modifiable risk factor is age. The neuroepidemiology of PD is complex with susceptibility genes and a number of modifiable risk factors that can increase and others that can mitigate risk and outcome. PMID- 27720004 TI - Epidemiology of Ischemic Stroke. AB - Ischemic stroke is a heterogeneous multifactorial disorder recognized by the sudden onset of neurologic signs related directly to the sites of injury in the brain where the morbid process occurs. The evaluation of complex neurologic disorders, such as stroke, in which multiple genetic and epigenetic factors interact with environmental risk factors to increase the risk has been revolutionized by the genome-wide association studies (GWAS) approach. This article reviews salient aspects of ischemic stroke emphasizing the impact of neuroepidemiology and GWAS. PMID- 27720005 TI - Epidemiology of Brain Tumors. AB - Brain tumors are the commonest solid tumor in children, leading to significant cancer-related mortality. Several hereditary syndromes associated with brain tumors are nonfamilial. Ionizing radiation is a well-recognized risk factor for brain tumors. Several industrial exposures have been evaluated for a causal association with brain tumor formation but the results are inconclusive. A casual association between the common mutagens of tobacco, alcohol, or dietary factors has not yet been established. There is no clear evidence that the incidence of brain tumors has changed over time. This article presents the descriptive epidemiology of the commonest brain tumors of children and adults. PMID- 27720008 TI - Erratum. PMID- 27720002 TI - Alzheimer Disease and Its Growing Epidemic: Risk Factors, Biomarkers, and the Urgent Need for Therapeutics. AB - Alzheimer disease (AD) represents one of the greatest medical challenges of this century; the condition is becoming increasingly prevalent worldwide and no effective treatments have been developed for this terminal disease. Because the disease manifests at a late stage after a long period of clinically silent neurodegeneration, knowledge of the modifiable risk factors and the implementation of biomarkers is crucial in the primary prevention of the disease and presymptomatic detection of AD, respectively. This article discusses the growing epidemic of AD and antecedent risk factors in the disease process. Disease biomarkers are discussed, and the implications that this may have for the treatment of this currently incurable disease. PMID- 27720006 TI - The Epidemiology of Neuromuscular Diseases. AB - Neuromuscular disorders as a group are linked by anatomy with significant differences in pathogenetic mechanisms, clinical expression, and time course of disease. Each neuromuscular disease is relatively uncommon, yet causes a significant burden of disease socioeconomically. Epidemiologic studies in different global regions have demonstrated certain neuromuscular diseases have increased incidence and prevalence rates over time. Understanding differences in global epidemiologic trends will aid clinical research and policies focused on prevention of disease. There is a critical need to understand the global impact of neuromuscular diseases using metrics currently established for communicable and noncommunicable diseases. PMID- 27720009 TI - The Journey of Lipoproteins Through the Cell: One Birthplace, Multiple Destinations. AB - Bacterial lipoproteins are a very diverse group of proteins characterized by the presence of an N-terminal lipid moiety that serves as a membrane anchor. Lipoproteins have a wide variety of crucial functions, ranging from envelope biogenesis to stress response. In Gram-negative bacteria, lipoproteins can be targeted to various destinations in the cell, including the periplasmic side of the cytoplasmic or outer membrane, the cell surface or the external milieu. The sorting mechanisms have been studied in detail in Escherichia coli, but exceptions to the rules established in this model bacterium exist in other bacteria. In this chapter, we will present the current knowledge on lipoprotein sorting in the cell. Our particular focus will be on the surface-exposed lipoproteins that appear to be much more common than previously assumed. We will discuss the different targeting strategies, provide numerous examples of surface exposed lipoproteins and discuss the techniques used to assess their surface exposure. PMID- 27720011 TI - Polar Marine Microorganisms and Climate Change. AB - The large diversity of marine microorganisms harboured by oceans plays an important role in planet sustainability by driving globally important biogeochemical cycles; all primary and most secondary production in the oceans is performed by microorganisms. The largest part of the planet is covered by cold environments; consequently, cold-adapted microorganisms have crucial functional roles in globally important environmental processes and biogeochemical cycles cold-adapted extremophiles are a remarkable model to shed light on the molecular basis of survival at low temperature. The indigenous populations of Antarctic and Arctic microorganisms are endowed with genetic and physiological traits that allow them to live and effectively compete at the temperatures prevailing in polar regions. Some genes, e.g. glycosyltransferases and glycosylsynthetases involved in the architecture of the cell wall, may have been acquired/retained during evolution of polar strains or lost in tropical strains. This present work focusses on temperature and its role in shaping microbial adaptations; however, in assessing the impacts of climate changes on microbial diversity and biogeochemical cycles in polar oceans, it should not be forgotten that physiological studies need to include the interaction of temperature with other abiotic and biotic factors. PMID- 27720010 TI - The Impact of Gene Silencing on Horizontal Gene Transfer and Bacterial Evolution. AB - The H-NS family of DNA-binding proteins is the subject of intense study due to its important roles in the regulation of horizontally acquired genes critical for virulence, antibiotic resistance, and metabolism. Xenogeneic silencing proteins, typified by the H-NS protein of Escherichia coli, specifically target and downregulate expression from AT-rich genes by selectively recognizing specific structural features unique to the AT-rich minor groove. In doing so, these proteins facilitate bacterial evolution; enabling these cells to engage in horizontal gene transfer while buffering potential any detrimental fitness consequences that may result from it. Xenogeneic silencing and counter-silencing explain how bacterial cells can evolve effective gene regulatory strategies in the face of rampant gene gain and loss and it has extended our understanding of bacterial gene regulation beyond the classic operon model. Here we review the structures and mechanisms of xenogeneic silencers as well as their impact on bacterial evolution. Several H-NS-like proteins appear to play a role in facilitating gene transfer by other mechanisms including by regulating transposition, conjugation, and participating in the activation of virulence loci like the locus of enterocyte effacement pathogenicity island of pathogenic strains of E. coli. Evidence suggests that the critical determinants that dictate whether an H-NS-like protein will be a silencer or will perform a different function do not lie in the DNA-binding domain but, rather, in the domains that control oligomerization. This suggests that H-NS-like proteins are transcription factors that both recognize and alter the shape of DNA to exert specific effects that include but are not limited to gene silencing. PMID- 27720013 TI - Preface. PMID- 27720012 TI - The Making and Taking of Lipids: The Role of Bacterial Lipid Synthesis and the Harnessing of Host Lipids in Bacterial Pathogenesis. AB - In order to survive environmental stressors, including those induced by growth in the human host, bacterial pathogens will adjust their membrane physiology accordingly. These physiological changes also include the use of host-derived lipids to alter their own membranes and feed central metabolic pathways. Within the host, the pathogen is exposed to many stressful stimuli. A resulting adaptation is for pathogens to scavenge the host environment for readily available lipid sources. The pathogen takes advantage of these host-derived lipids to increase or decrease the rigidity of their own membranes, to provide themselves with valuable precursors to feed central metabolic pathways, or to impact host signalling and processes. Within, we review the diverse mechanisms that both extracellular and intracellular pathogens employ to alter their own membranes as well as their use of host-derived lipids in membrane synthesis and modification, in order to increase survival and perpetuate disease within the human host. Furthermore, we discuss how pathogen employed mechanistic utilization of host-derived lipids allows for their persistence, survival and potentiation of disease. A more thorough understanding of all of these mechanisms will have direct consequences for the development of new therapeutics, and specifically, therapeutics that target pathogens, while preserving normal flora.

PMID- 27720016 TI - Asthma phenotypes in inner-city children. AB - BACKGROUND: Children with asthma in low-income urban areas have high morbidity. Phenotypic analysis in these children is lacking, but may identify characteristics to inform successful tailored management approaches. OBJECTIVE: We sought to identify distinct asthma phenotypes among inner-city children receiving guidelines-based management. METHODS: Nine inner-city asthma consortium centers enrolled 717 children aged 6 to 17 years. Data were collected at baseline and prospectively every 2 months for 1 year. Participants' asthma and rhinitis were optimally managed by study physicians on the basis of guidelines. Cluster analysis using 50 baseline and 12 longitudinal variables was performed in 616 participants completing 4 or more follow-up visits. RESULTS: Five clusters (designated A through E) were distinguished by indicators of asthma and rhinitis severity, pulmonary physiology, allergy (sensitization and total serum IgE), and allergic inflammation. In comparison to other clusters, cluster A was distinguished by lower allergy/inflammation, minimally symptomatic asthma and rhinitis, and normal pulmonary physiology. Cluster B had highly symptomatic asthma despite high step-level treatment, lower allergy and inflammation, and mildly altered pulmonary physiology. Cluster C had minimally symptomatic asthma and rhinitis, intermediate allergy and inflammation, and mildly impaired pulmonary physiology. Clusters D and E exhibited progressively higher asthma and rhinitis symptoms and allergy/inflammation. Cluster E had the most symptomatic asthma while receiving high step-level treatment and had the highest total serum IgE level (median, 733 kU/L), blood eosinophil count (median, 400 cells/mm3), and allergen sensitizations (15 of 22 tested). CONCLUSIONS: Allergy distinguishes asthma phenotypes in urban children. Severe asthma often coclusters with highly allergic children. However, a symptomatic phenotype with little allergy or allergic inflammation was identified. PMID- 27720017 TI - Distinguishing characteristics of difficult-to-control asthma in inner-city children and adolescents. AB - BACKGROUND: Treatment levels required to control asthma vary greatly across a population with asthma. The factors that contribute to variability in treatment requirements of inner-city children have not been fully elucidated. OBJECTIVE: We sought to identify the clinical characteristics that distinguish difficult-to control asthma from easy-to-control asthma. METHODS: Asthmatic children aged 6 to 17 years underwent baseline assessment and bimonthly guideline-based management visits over 1 year. Difficult-to-control and easy-to-control asthma were defined as daily therapy with 500 MUg of fluticasone or greater with or without a long acting beta-agonist versus 100 MUg or less assigned on at least 4 visits. Forty four baseline variables were used to compare the 2 groups by using univariate analyses and to identify the most relevant features of difficult-to-control asthma by using a variable selection algorithm. Nonlinear seasonal variation in longitudinal measures (symptoms, pulmonary physiology, and exacerbations) was examined by using generalized additive mixed-effects models. RESULTS: Among 619 recruited participants, 40.9% had difficult-to-control asthma, 37.5% had easy-to control asthma, and 21.6% fell into neither group. At baseline, FEV1 bronchodilator responsiveness was the most important characteristic distinguishing difficult-to-control asthma from easy-to-control asthma. Markers of rhinitis severity and atopy were among the other major discriminating features. Over time, difficult-to-control asthma was characterized by high exacerbation rates, particularly in spring and fall; greater daytime and nighttime symptoms, especially in fall and winter; and compromised pulmonary physiology despite ongoing high-dose controller therapy. CONCLUSIONS: Despite good adherence, difficult-to-control asthma showed little improvement in symptoms, exacerbations, or pulmonary physiology over the year. In addition to pulmonary physiology measures, rhinitis severity and atopy were associated with high-dose asthma controller therapy requirement. PMID- 27720019 TI - Pharmacogenomics and adverse drug reactions: Primetime and not ready for primetime tests. AB - Adverse drug reactions (ADRs) are a relatively common cause of morbidity and mortality. Many factors can contribute to ADRs, including genetics. The degree to which genetics contributes to ADRs is not entirely clear and varies by drug, as well as the type of ADR. Pharmacogenetics and, more recently, pharmacogenomics have been applied to the field of ADRs for both predictable ADRs and hypersensitivity drug reactions. Evaluations for glucose-6-phosphate dehydrogenase and thiopurine S-methyltransferase are commonplace clinical tests to reduce hematologic problems associated with drugs, such as dapsone and azathioprine, respectively. Numerous pharmacogenetic associations have been discovered for immediate hypersensitivity reactions to beta-lactams, aspirin, and nonsteroidal anti-inflammatory drugs; however, the clinical utility of testing for these genetic associations has not been established. In contrast, pharmacogenetic testing for HLA-B*1502 before carbamazepine in patients of certain Asian ethnicities and testing for HLA-B*5701 before abacavir treatment are recommended. This review will focus on pharmacogenetics and pharmacogenomics and their role in reducing ADRs, especially those caused by drug hypersensitivity reactions. PMID- 27720018 TI - Pathways through which asthma risk factors contribute to asthma severity in inner city children. AB - BACKGROUND: Pathway analyses can be used to determine how host and environmental factors contribute to asthma severity. OBJECTIVE: To investigate pathways explaining asthma severity in inner-city children. METHODS: On the basis of medical evidence in the published literature, we developed a conceptual model to describe how 8 risk-factor domains (allergen sensitization, allergic inflammation, pulmonary physiology, stress, obesity, vitamin D, environmental tobacco smoke [ETS] exposure, and rhinitis severity) are linked to asthma severity. To estimate the relative magnitude and significance of hypothesized relationships among these domains and asthma severity, we applied a causal network analysis to test our model in an Inner-City Asthma Consortium study. Participants comprised 6- to 17-year-old children (n = 561) with asthma and rhinitis from 9 US inner cities who were evaluated every 2 months for 1 year. Asthma severity was measured by a longitudinal composite assessment of day and night symptoms, exacerbations, and controller usage. RESULTS: Our conceptual model explained 53.4% of the variance in asthma severity. An allergy pathway (linking allergen sensitization, allergic inflammation, pulmonary physiology, and rhinitis severity domains to asthma severity) and the ETS exposure pathway (linking ETS exposure and pulmonary physiology domains to asthma severity) exerted significant effects on asthma severity. Among the domains, pulmonary physiology and rhinitis severity had the largest significant standardized total effects on asthma severity (-0.51 and 0.48, respectively), followed by ETS exposure (0.30) and allergic inflammation (0.22). Although vitamin D had modest but significant indirect effects on asthma severity, its total effect was insignificant (0.01). CONCLUSIONS: The standardized effect sizes generated by a causal network analysis quantify the relative contributions of different domains and can be used to prioritize interventions to address asthma severity.

PMID- 27720022 TI - Lifetime effects of infection with bovine leukemia virus on longevity and milk production of dairy cows. AB - Enzootic bovine leukosis (EBL) is an economically important disease of dairy cattle caused by bovine leukemia virus (BLV). The economic impacts of the infection have been debated in the literature. The present study was conducted to determine the lifetime effects of BLV infection on longevity and milk production of dairy cows in Canada. The data were aggregated from a combination of two data sets: 1) BLV serum-ELISA test results from Canada-wide surveys of production limiting diseases, which took place between 1998 and 2003 in 8 provinces, and 2) longitudinal production data for all cows in the former study, extracted from the Canadian dairy herd improvement database. All participant cows had been culled or died by the onset of this study. A historical cohort study was designed, including cows which tested positive to BLV-antibodies in their first lactation (positive cohort, n=1858) and cows which tested negative in their second or later lactations (negative cohort, n=2194). To assess the impacts of infection with BLV on longevity (the number of lifetime lactations), a discrete-time survival analysis was carried out. The effect of BLV on the lifetime milk production (the sum of all life 305-day milk production) was evaluated using a multilevel linear regression model. Overall, 4052 cows from 348 herds met the eligibility criteria and were enrolled in the study. In the longevity model, the interaction term between time (lactation number) and BLV-status was highly significant. Cows which were positive to BLV had consistently greater probabilities of being culled (or dying) than the test-negative cows. In the milk production model, the interaction term between BLV-status and longevity of the cows was highly significant; indicating that lifetime BLV effects on the total milk production was dependent on the lactation in which the study cows were culled/died. Infected cows with 2 and 3 lactations showed significantly lower life milk productions [-2554kg (-3609 to -1500) and -1171kg (-2051 to -292), respectively] compared with their negative counterparts with 2 and 3 lactations. As the cows lived longer (>3 lactations), the differences in life milk production between the two cohorts were no longer significant. Overall, it was predicted that the test-positive cows produced substantially lower milk compared to the test-negative cows throughout their study lifespans. With the high prevalence of BLV in Canadian dairy cows and its detrimental economic impacts, pursuing broad-based control programs in Canada should be evaluated. PMID- 27720020 TI - Exome and genome sequencing for inborn errors of immunity. AB - The advent of next-generation sequencing (NGS) in 2010 has transformed medicine, particularly the growing field of inborn errors of immunity. NGS has facilitated the discovery of novel disease-causing genes and the genetic diagnosis of patients with monogenic inborn errors of immunity. Whole-exome sequencing (WES) is presently the most cost-effective approach for research and diagnostics, although whole-genome sequencing offers several advantages. The scientific or diagnostic challenge consists in selecting 1 or 2 candidate variants among thousands of NGS calls. Variant- and gene-level computational methods, as well as immunologic hypotheses, can help narrow down this genome-wide search. The key to success is a well-informed genetic hypothesis on 3 key aspects: mode of inheritance, clinical penetrance, and genetic heterogeneity of the condition. This determines the search strategy and selection criteria for candidate alleles. Subsequent functional validation of the disease-causing effect of the candidate variant is critical. Even the most up-to-date dry lab cannot clinch this validation without a seasoned wet lab. The multifariousness of variations entails an experimental rigor even greater than traditional Sanger sequencing-based approaches in order not to assign a condition to an irrelevant variant. Finding the needle in the haystack takes patience, prudence, and discernment. PMID- 27720023 TI - Perceptions of French private veterinary practitioners' on their role in organic dairy farms and opportunities to improve their advisory services for organic dairy farmers. AB - Veterinarians could be the expected sparring partners of organic dairy farmers in promoting animal health which is one of the main organic principles. However, in the past organic dairy farmers did not always consider veterinarians to be pertinent advisors for them. The objectives of this study are - from private veterinary practitioners' point of views- i) to describe the roles of veterinarians today in organic dairy farmers' animal health promotion strategies, ii) to identify factors related to organic farming which determine their role on organic dairy farms, and, iii) to identify opportunities for improvement of veterinarians' advisory services for organic dairy herds. Fourteen veterinarians, providing herd health advisory services to dairy farmers, were interviewed using qualitative semi-structured research interviews. A modified approach to Grounded Theory was used for data collection and analysis. Most often veterinarians had only contact with the organic dairy farmers in cases of individual ill animals or acute herd health problems. Even though certain veterinarians experienced situations and approaches of animal health and welfare on organic dairy farms not meeting their standards, they were not always able to establish themselves an advisory role supporting farmers in improving this. Indeed, organic production principles, regulations and farmers' health approaches challenged veterinarians' values on animal health and welfare and their perceptions of 'good veterinary practices'. Also, some veterinarians considered that there was no direct economic interest for them in the organic dairy sector and that could diminish their willingness to invest in this sector. Possible opportunities for improvement were identified; for example proposing more proactively advice via existing organisations, by making adaptations to advisory services for the organic sector and/or by dissociating veterinarians' curative role from their advisory role in disease prevention. PMID- 27720024 TI - Changes in perceptions and motivators that influence the implementation of on farm Salmonella control measures by pig farmers in England. AB - This study presents British farmers' perception of, and barriers to, implementing Salmonella control on pig farms. Four farms that had implemented interventions and their 33 close contacts (known to the intervention farmers) took part in interviews before (phase 1) and after (phase 2) intervention trials to assess the difference in perception over time. Their results were compared against those from nine randomly selected control farms. The hypothesis was that farms implementing interventions whether or not successful, would influence their close contacts' opinion over time. Based on a 'pathway to disease control' model, three intrinsic factors known to influence motivation - attitudes, social norms and self-efficacy - were evaluated. Farmers mentioned that successful interventions on a farm would attract their attention. The use of an appropriate communication strategy is therefore recommended to stimulate farmers' intent to implement control measures. Both before and after the intervention trials, all farmers had a positive attitude towards Salmonella control and felt that their peers and authorities were supportive of controlling Salmonella on farms. In phase 2, however, farmers were more likely to want to share the burden of control with other stakeholders along the food chain and their belief in self-efficacy had weakened. Whilst social norms were not associated with an intention to take action on control, a positive attitude towards Salmonella control and a belief in self-efficacy were more likely to result in an intent to control. In phase 2, farmers with an intent to implement an intervention appeared to have a greater, but not significant positive belief in self-efficacy (p=0.108). This study confirmed that farmers recognised their responsibility for controlling Salmonella in pork - even though their confidence in their ability to control Salmonella decreased over time - and believed that responsibility should be shared with the rest of the production chain. It showed that farmers trusted their veterinarian as a source of advice to guide them during the process of implementing change, though an increase in farms' Salmonella seroprevalence score (Zoonosis National Control Programme (ZNCP) score) especially for those with a low ZNCP score was also likely to influence their behaviour. Getting concrete feedback from customers or a tangible benefit from their action was a strong incentive especially for farms with a ZNCP score higher than 50%. The study also revealed a need to validate which measures are effective as farmers did not perceive that the current advised interventions were worth the additional effort. PMID- 27720025 TI - Evaluating the efficacy of regionalisation in limiting high-risk livestock trade movements. AB - Many countries implement regionalisation as a measure to control economically important livestock diseases. Given that regionalisation highlights the difference in disease risk between animal subpopulations, this may discourage herd managers in low-risk areas from purchasing animals from high-risk areas to protect the disease-free status of their herds. Using bovine tuberculosis (bTB) in New Zealand as a case example, we develop a novel network simulation model to predict how much the frequency of cattle movements between different disease control areas (DCAs) could theoretically change if herd managers adopted the safest practices (preferentially purchasing cattle from areas with the lowest risk of bTB), if herd managers adopted the riskiest practices (preferentially purchasing cattle from areas with the greatest risk of bTB), or if herd managers made trade decisions completely at random (purchasing cattle without consideration for bTB disease risk). A modified configuration wiring algorithm was used in the network simulation model to preserve key temporal, spatial, and demographic attributes of cattle movement patterns. The simulated frequencies of cattle movements between DCAs in each of the three behavioural scenarios were compared with the actual frequency of cattle movements that occurred between 1st July 2010 and 30th June 2011. Our results showed that the observed frequency of cattle movements from high-risk areas into low-risk areas was significantly less than if trade decisions were made completely at random, but still significantly greater than if herd managers made the safest possible trade decisions. This suggests that while New Zealand cattle farmers may have adopted risk-averse trading behaviour in response to regionalisation, there are other underlying factors driving livestock trade, such as established supplier-buyer relationships and heterogeneous individual perceptions towards disease risk, which may reduce the potential efficacy of regionalisation as a disease control strategy. Physical constraints and socio-psychological factors that determine herd managers' livestock trading behaviour warrant further studies to better understand how herd managers respond to future livestock disease regulations. The flexibility of a network re-wiring framework presented in this study allows such a behavioural response to be incorporated into a disease simulation model, which will in turn facilitate a better evaluation of disease control strategies. PMID- 27720026 TI - Application of slightly acidic electrolyzed water for decontamination of stainless steel surfaces in animal transport vehicles. AB - The effectiveness of slightly acidic electrolyzed water (SAEW) in reducing Escherichia coli, Salmonella typhimurim, Staphylococcus aureus or bacterial mixtures on stainless steel surfaces was evaluated and compared its efficacy with composite phenol solution for reducing total aerobic bacteria in animal transport vehicles. Stainless steel surfaces were inoculated with these strains individually or in a mixture, and sprayed with SAEW, composite phenol, or alkaline electrolyzed water for 0.5, 1, 1.5 and 2min. The bactericidal activity of SAEW increased with increasing available chlorine concentration and spraying duration. The SAEW solution of 50mgl-1 of available chlorine concentration showed significantly higher effectiveness than composite phenol in reducing the pathogens on stainless steel surfaces (P<0.05). Complete inactivation of pathogens on stainless steel surfaces were observed after treatment with alkaline electrolyzed water followed by SAEW at 50mgl-1 of available chlorine concentration for 2min or alkaline electrolyzed water treatment followed by SAEW treatment at 90mgl-1 of available chlorine concentration for 0.5min. The efficacy of SAEW in reducing total aerobic bacteria in animal transport vehicles was also determined. Vehicles in the disinfection booth were sprayed with the same SAEW, alkaline electrolyzed water and composite phenol solutions using the automatic disinfection system. Samples from vehicle surfaces were collected with sterile cotton swabs before and after each treatment. No significant differences in bactericidal efficiency were observed between SAEW and composite phenol for reducing total aerobic bacteria in the vehicles (P>0.05). SAEW was also found to be more effective when used in conjunction with alkaline electrolyzed water. Results suggest that the bactericidal efficiency of SAEW was higher than or equivalent to that of composite phenol and SAEW may be used as effective alternative for reducing microbial contamination of animal transport vehicles. PMID- 27720027 TI - Lameness in dairy heifers; impacts of hoof lesions present around first calving on future lameness, milk yield and culling risk. AB - The importance of lameness in primiparous dairy heifers is increasingly recognised. Although it is accepted that clinical lameness in any lactation increases the risk of future lameness, the impact of foot lesions during the first lactation on long-term lameness risk is less clear. This retrospective cohort study aimed to investigate the impacts of foot lesions occurring around the time of first calving in heifers on future lameness risk, daily milk yield and survival within a dairy herd. Records were obtained for 158 heifers from one UK dairy herd. Heifers were examined in 2 month blocks from 2 months pre-calving through to 4 months post-calving. Sole lesions and white line lesions were scored on a zero to 10 scale and digital dermatitis on a zero to 3 scale. Outcomes investigated were; lameness risk based on weekly locomotion scores, average daily milk yield and culling risk. Mixed effect models were used to investigate associations between maximum lesion scores and outcomes. Lesion scores in the highest score categories for claw horn lesions (sole lesions and white line lesions) in the 2 to 4 month post-calving period were associated with an increased risk of future lameness; heifers with white line lesion scores >=3 compared with scores zero to 1 and heifers with sole lesion scores >=4 compared with score 2, at this time point, had a predicted increased risk of future lameness of 1.6 and 2.6 respectively. Sole lesions >=4 were also associated with a reduction in average daily milk yield of 2.68kg. Managing heifers to reduce claw horn lesions during this time period post-calving may provide health, welfare and production benefits for the long-term future of those animals. A novel finding from the study was that mild lesion scores compared with scores zero to 1, were associated with a reduced risk of future lameness for white line lesions and sole lesions occurring in the pre-calving or 2 to 4 months post calving periods respectively. Mild sole lesions in the pre-calving period were also associated with a reduced risk of premature culling. One hypothesis for this result is that a mild insult may result in adaptive changes to the foot leading to greater biomechanical resilience and so increased longevity. PMID- 27720028 TI - A Bayesian micro-simulation to evaluate the cost-effectiveness of interventions for mastitis control during the dry period in UK dairy herds. AB - Importance of the dry period with respect to mastitis control is now well established although the precise interventions that reduce the risk of acquiring intramammary infections during this time are not clearly understood. There are very few intervention studies that have measured the clinical efficacy of specific mastitis interventions within a cost-effectiveness framework so there remains a large degree of uncertainty about the impact of a specific intervention and its costeffectiveness. The aim of this study was to use a Bayesian framework to investigate the cost-effectiveness of mastitis controls during the dry period. Data were assimilated from 77 UK dairy farms that participated in a British national mastitis control programme during 2009-2012 in which the majority of intramammary infections were acquired during the dry period. The data consisted of clinical mastitis (CM) and somatic cell count (SCC) records, herd management practices and details of interventions that were implemented by the farmer as part of the control plan. The outcomes used to measure the effectiveness of the interventions were i) changes in the incidence rate of clinical mastitis during the first 30days after calving and ii) the rate at which cows gained new infections during the dry period (measured by SCC changes across the dry period from <200,000cells/ml to >200,000cells/ml). A Bayesian one-step microsimulation model was constructed such that posterior predictions from the model incorporated uncertainty in all parameters. The incremental net benefit was calculated across 10,000 Markov chain Monte Carlo iterations, to estimate the cost-benefit (and associated uncertainty) of each mastitis intervention. Interventions identified as being cost-effective in most circumstances included selecting dry-cow therapy at the cow level, dry-cow rations formulated by a qualified nutritionist, use of individual calving pens, first milking cows within 24h of calving and spreading bedding evenly in dry-cow yards. The results of this study highlighted the efficacy of specific mastitis interventions in UK conditions which, when incorporated into a costeffectiveness framework, can be used to optimize decision making in mastitis control. This intervention study provides an example of how an intuitive and clinically useful Bayesian approach can be used to form the basis of an on-farm decision support tool. PMID- 27720029 TI - Bovine respiratory syncytial virus and bovine coronavirus antibodies in bulk tank milk - risk factors and spatial analysis. AB - Bovine respiratory syncytial virus (BRSV) and bovine coronavirus (BCoV) are considered widespread among cattle in Norway and worldwide. This cross-sectional study was conducted based on antibody-ELISA of bulk tank milk (BTM) from 1347 herds in two neighboring counties in western Norway. The study aims were to determine the seroprevalence at herd level, to evaluate risk factors for BRSV and BCoV seropositivity, and to assess how these factors were associated with the spatial distribution of positive herds. The overall prevalence of BRSV and BCoV positive herds in the region was 46.2% and 72.2%, respectively. Isopleth maps of the prevalence risk distribution showed large differences in prevalence risk across the study area, with the highest prevalence in the northern region. Common risk factors of importance for both viruses were herd size, geographic location, and proximity to neighbors. Seropositivity for one virus was associated with increased odds of seropositivity for the other virus. Purchase of livestock was an additional risk factor for BCoV seropositivity, included in the model as in degree, which was defined as the number of incoming movements from individual herds, through animal purchase, over a period of five years. Local dependence and the contribution of risk factors to this effect were assessed using the residuals from two logistic regression models for each virus. One model contained only the x- and y- coordinates as predictors, the other had all significant predictors included. Spatial clusters of high values of residuals were detected using the normal model of the spatial scan statistic and visualized on maps. Adjusting for the risk factors in the final models had different impact on the spatial clusters for the two viruses: For BRSV the number of clusters was reduced from six to four, for BCoV the number of clusters remained the same, however the log likelihood ratios changed notably. This indicates that geographical differences in proximity to neighbors, herd size and animal movements explain some of the spatial clusters of BRSV- and BCoV seropositivity, but far from all. The remaining local dependence in the residuals show that the antibody status of one herd is influenced by the antibody status of its neighbors, indicating the importance of indirect transmission and that increased biosecurity routines might be an important preventive strategy. PMID- 27720030 TI - Assessing, and understanding, European organic dairy farmers' intentions to improve herd health. AB - Many believe the health status of organic dairy herds in Europe should be improved to meet consumers' and legislators' expectations to improve animal welfare. This paper reports on a study in four countries that examined dairy farmers' intentions towards improving the health status of their organic herds through the use of the Theory of Planned Behaviour. It was found that farmers across the countries were positive about taking additional preventative measures to improve the health status of their herds. They believed this would not only improve herd physical performance, such as milk yield and fertility, but also achieve greater cost effectiveness and improved job satisfaction for them. Most study farmers would implement a tailored package of improvement measures designed by the study team with higher uptake most likely being by younger farmers, those who make greater use of veterinarians and professional advisory services, and those supplying specialist milk-marketing chains. Furthermore, farmers will be most likely to take-up additional health promotion if compatible with their everyday activities and if they have strong business performance goals aimed at maximising the physical performance of the herd.

AB - Newcastle Disease (ND) is a highly infectious disease of poultry that seriously impacts on food security and livelihoods of livestock farmers and communities in tropical regions of the world. ND is a constant problem in the eastern province of Zambia which has more than 740 000 rural poultry. Very few studies give a situational analysis of the disease that can be used for disease control planning in the region. With this background in mind, a retrospective epidemiological study was conducted using Newcastle Disease data submitted to the eastern province headquarters for the period from 1989 to 2014. The study found that Newcastle Disease cases in eastern Zambia followed a seasonal and cyclic pattern with peaks in the hot dry season (Overall Seasonal Index 1.1) as well as cycles every three years with an estimated provincial incidence range of 0.16 to 1.7% per year. Annual trends were compared with major intervention policies implemented by the Zambian government, which often received donor support from the international community during the study period. Aid delivered through government programmes appeared to have no major impact on ND trends between 1989 and 2014 and reasons for this are discussed. There were apparent spatial shifts in districts with outbreaks over time which could be as a result of veterinary interventions chasing outbreaks rather than implementing uniform control. Data was also fitted to a predictive time series model for ND which could be used to plan for future ND control. Time series modelling showed an increasing trend in ND annual incidence over 25 years if existing interventions continue. A different approach to controlling the disease is needed if this trend is to be halted. Conversely, the positive trend may be a function of improved reporting by farmers as a result of more awareness of the disease. PMID- 27720033 TI - Patient, Family Centred Care. PMID- 27720034 TI - Parent and nurse perceptions on the quality of family-centred care in 11 European NICUs. AB - BACKGROUND: Family-centred care (FCC) is a state-of-the-art practice in neonatal intensive care units (NICU) based on its shown benefits on the well-being of both infants and parents. However, there is no systematic knowledge about how FCC is implemented in different European contexts. OBJECTIVES: To describe parents' presence and the quality of FCC from the perspectives of mothers, fathers and nurses in 11 European NICUs. METHODS: A prospective survey was conducted in Finland, Sweden, Norway, Estonia, Spain and Italy. The perceived quality of FCC was measured using 8 text-message questions sent to the parents' mobile phones, one question each day, during the infant's hospital stay. Nurses answered corresponding questions through a Web questionnaire during a 3-month period. The responses were rated on a 7-point Likert scale. Parents who were not present in the unit during the day used a "0" response. RESULTS: A total of 262 families of preterm infants born before 35 gestational weeks participated in the study. Mothers gave 5045 responses, fathers gave 3971 responses and nurses gave 11,132 answers. The mothers were present during 92.7% and the fathers during 77.9% of the study days. The mothers rated the quality of FCC slightly higher than the fathers did (5.8 [95% CI 5.7-5.9] vs. 5.7 [95% CI 5.6-5.8], mean difference of 0.12 [95% CI 0.05-0.2], p<0.001). There was wide variation in the parents' presence and the quality of FCC between the units. The weakest aspects of FCC were emotional support, parents' participation in decision-making and fathers' participation in infant care. The perceived quality of FCC between the nurses and parents were comparable. CONCLUSIONS: This study showed a high perceived quality of FCC in 11 European units, as indicated by both parents and nurses. The innovative data-collection method and instrument successfully quantified each unit's FCC profile for further quality improvement and should be trialled in other NICUs and countries. PMID- 27720035 TI - Kinetics of docosahexaenoic acid ethyl ester accumulation in dog plasma and brain. AB - This study explores dog plasma and brain fatty acid composition achieved after long-term supplementation at high DHA doses. A 90% concentrate of DHA Ethyl Ester (DHA-EE) administered by oral gavage to Beagle dogs at doses of 100, 500, 1000, and 2000mg/kg bw/day for 8 weeks resulted in DHA increases in both plasma and brain. In a subsequent 9-month study, DHA-EE was administered at 150, 1000 and 2000mg/kg bw/day. Plasma DHA increased between 150 and 1000mg/kg bw/day but not between 1000 and 2000mg/kg bw/day and there were increases from Day 1to 92 but not between days 92 and 273. Doses >500mg/kg bw/day in the 8-week and all doses in the 9-month study resulted in DHA increases in the brain. The dose of 150mg/k gbw/day is sufficient to achieve maximal brain concentrations if DHA is administered chronically. For shorter than 6 months of supplementation, higher doses are required. PMID- 27720038 TI - The effect of n-3 LCPUFA supplementation on oxidative stress and inflammation in the placenta and maternal plasma during pregnancy. AB - Pregnancy represents a state of heightened oxidative stress and inflammation, and these processes are further increased in pregnancy complications. The quality of the maternal diet is directly associated with maternal health and wellbeing, pregnancy and fetal outcomes, as well as the risk of pregnancy complications. Long chain polyunsaturated fatty acids (LCPUFAs) have significant potential to modify placental and fetal lipid environments and thereby modulate health outcomes. The omega-3 (n-3) LCPUFA in particular have been shown to exhibit both antioxidant and anti-inflammatory properties, and have potential therapeutic applications in reducing oxidative damage and inflammation during pregnancy. The purpose of this review is to provide an overview of our current understanding of the impact of maternal n-3 LCPUFA supplementation on oxidative stress and inflammation during pregnancy, with a particular focus on effects on the mother and the placenta. PMID- 27720036 TI - Differences in long chain polyunsaturates composition and metabolism in male and female rats. AB - Human studies and some animal work have shown more docosahexaenoic acid (DHA) and arachidonic acid (ARA) was accumulated or converted from precursors in females compared to males. This study explored in-depth the effect of gender on fatty acid composition and polyunsaturated fatty acid metabolism in rats fed one of two well-defined diets containing 10% total fat. One diet contained 15% of linoleic acid (LA) and 3% of alpha-linolenic acid (ALA) of the total fatty acids (LA+ALA diet), while the other diet contained 15% LA and 0.05% ALA (LA diet). At the age of 20 weeks, all animals were orally administered a single dose of a mixture of deuterium-labeled LA and ALA. Caudal venous blood was then drawn at 0, 2, 4, 8, 12, 24, 48, 96 and 168h. The concentrations of the deuterated precursors and their metabolites in plasma total lipids were quantified by GC/MS negative chemical ionization. Endogenous fatty acids were quantified by GC/FID analysis. When expressed as the percentage of oral dosage, female rats accumulated more precursors and more products, deuterated DHA and deuterated n-6 docosapentaenoic acid (2H5-DPAn-6), in plasma than did male rats in both the LA+ALA diet and the LA diet. For the endogenous non-labeled PUFA, greater concentrations of DHA and DPAn-6 were similarly observed in female rats compared to males within each diet. A lower concentration of non-labeled ARA was observed only in female rats fed the LA+ALA diet. In summary, greater endogenous and exogenous DHA and DPAn-6 was observed in female rat plasma and this was independent of dietary ALA status. PMID- 27720037 TI - Inflammatory F2-isoprostane, prostaglandin F2alpha, pentraxin 3 levels and breast cancer risk: The Swedish Mammography Cohort. AB - INTRODUCTION: Breast cancer is a common cancer among women. Identifying cellular participation of F2-isoprostane, prostaglandin F2alpha (PGF2alpha) and pentraxin 3 (PTX3) in cancer we evaluated whether their prediagnostic systemic levels that originate from different inflammatory pathways were associated with breast cancer risk. METHODS: Seventy-eight breast cancer cases diagnosed after blood collection and 797 controls from the Swedish Mammography Cohort were analysed for urinary F2 isoprostane, PGF2alpha and plasma PTX3 levels. RESULTS: None of the biomarkers investigated were significantly associated with breast cancer risk. However, there was the suggestion of an inverse association with PTX3 with multivariable adjusted ORs (95% CI) of 0.56 (95% CI=0.29-1.06) and 0.67 (95% CI=0.35-1.28) for the second and third tertiles, respectively (ptrend=0.20). No associations were observed between F2-isoprostane (OR=0.87; 95% CI=0.48-1.57; ptrend=0.67) and PGF2alpha metabolite (OR=1.03; 95% CI=0.56-1.88; ptrend=0.91) comparing the top to bottom tertiles. CONCLUSIONS: The systemic levels of F2-isoprostane, PGF2alpha and PTX3 witnessed in women who later developed breast cancer may not provide prognostic information regarding tumor development in spite of their known involvement in situ cellular context. These observations may indicate that other mechanisms exist in controlling cellular formation of F2-isoprostane, PGF2alpha and PTX3 and their systemic availability in breast cancer patients. PMID- 27720039 TI - Risk factors associated with plasma omega-3 fatty acid levels in patients with suspected coronary artery disease. AB - INTRODUCTION: We sought to determine the associations between plasma eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels and various cardiovascular risk factors and with the use of fish oil supplements (FOS). PATIENTS AND METHODS: Patients with suspected coronary artery disease (CAD) undergoing cardiac catheterization (n=433) were studied. Serum fatty acid (FA) composition, the concentrations of lipids and biomarkers of oxidative stress, and dietary/lifestyle factors were measured. RESULTS: FOS use was associated with a higher plasma EPA+DHA levels (3.7+/-1.5 vs. 2.6+/-1.1%, p<0.0001). However, there was no relationship between FOS dose (mg/day) and EPA+DHA levels in 76 patients reporting FOS use (r=-0.21, p=0.07). Lower levels were inversely associated with risk factor profiles including lower ApoB100/ApoA1 ratios (p<0.001). DISCUSSION AND CONCLUSIONS: Higher EPA+DHA levels characterized patients with lower CAD risk. The lack of relations between FOS dose and plasma EPA+DHA levels likely reflects uncaptured variability in EPA+DHA content of supplements. PMID- 27720040 TI - Elevated prostaglandin E metabolites and abnormal plasma fatty acids at baseline in pediatric cystic fibrosis patients: a pilot study. AB - BACKGROUND: Airway inflammation is a significant contributor to the morbidity of cystic fibrosis (CF) disease. One feature of this inflammation is the production of oxygenated metabolites, such as prostaglandins. Individuals with CF are known to have abnormal metabolism of fatty acids, typically resulting in reduced levels of linoleic acid (LA) and docosahexaenoic acid (DHA). METHODS: This is a randomized, double-blind, cross-over clinical trial of DHA supplementation with endpoints of plasma fatty acid levels and prostaglandin E metabolite (PGE-M) levels. Patients with CF age 6-18 years with pancreatic insufficiency were recruited. Each participant completed 3 four-week study periods: DHA at two different doses (high dose and low dose) and placebo with a minimum 4 week wash out between each period. Blood, urine, and exhaled breath condensate (EBC) were collected at baseline and after each study period for measurement of plasma fatty acids as well as prostaglandin E metabolites. RESULTS: Seventeen participants were enrolled, and 12 participants completed all 3 study periods. Overall, DHA supplementation was well tolerated without significant adverse events. There was a significant increase in plasma DHA levels with supplementation, but no significant change in arachidonic acid (AA) or LA levels. However, at baseline, AA levels were lower and LA levels were higher than previously reported for individuals with CF. Urine PGE-M levels were elevated in the majority of participants at baseline, and while levels decreased with DHA supplementation, they also decreased with placebo. CONCLUSIONS: Urine PGE-M levels are elevated at baseline in this cohort of pediatric CF patients, but there was no significant change in these levels with DHA supplementation compared to placebo. In addition, baseline plasma fatty acid levels for this cohort showed some difference to prior reports, including higher levels of LA and lower levels of AA, which may reflect changes in clinical care, and consequently warrants further investigation. PMID- 27720041 TI - Enriched dairy fat matrix diet prevents early life lipopolysaccharide-induced spatial memory impairment at adulthood. AB - Polyunsaturated fatty acids (PUFAs) are essential fatty acids, which are critical for brain development and later life cognitive functions. The main brain PUFAs are docosahexaenoic acid (DHA) for the n-3 family and arachidonic acid (ARA) for the n-6 family, which are provided to the post-natal brain by breast milk or infant formula. Recently, the use of dairy lipids (DL) in replacement of vegetable lipids (VL) was revealed to potently promote the accretion of DHA in the developing brain. Brain DHA, in addition to be a key component of brain development, display potent anti-inflammatory activities, which protect the brain from adverse inflammatory events. In this work, we evaluated the protective effect of partial replacement of VL by DL, supplemented or not with DHA and ARA, on post-natal inflammation and its consequence on memory. Mice were fed with diets poor in vegetal n-3 PUFA (Def VL), balanced in vegetal n-3/n-6 PUFA (Bal VL), balanced in dairy lipids (Bal DL) or enriched in DHA and ARA (Supp VL; Supp DL) from the first day of gestation until adulthood. At post-natal day 14 (PND14), pups received a single administration of the endotoxin lipopolysaccharide (LPS) and brain cytokine expression, microglia phenotype and neurogenesis were measured. In a second set of experiments, memory and neurogenesis were measured at adulthood. Overall, our data showed that lipid quality of the diet modulates early life LPS effect on microglia phenotype, brain cytokine expression and neurogenesis at PND14 and memory at adulthood. In particular, Bal DL diet protects from the adverse effect of early life LPS exposure on PND14 neurogenesis and adult spatial memory. PMID- 27720042 TI - Endocrine uncoupling of the trade-off between reproduction and somatic maintenance in eusocial insects. AB - In most animals reproduction trades off with somatic maintenance and survival. Physiologically this trade-off is mediated by hormones with opposite effects on reproduction and maintenance. In many insects, this regulation is achieved by an endocrine network that integrates insulin-like/IGF-1 signaling (IIS), juvenile hormone (JH), and the yolk precursor vitellogenin (Vg) (or, more generally, yolk proteins [YPs]). Downregulation of this network promotes maintenance and survival at the expense of reproduction. Remarkably, however, queens of highly eusocial social insects exhibit both enormous reproductive output and longevity, thus escaping the trade-off. Here we argue - based on recent evidence - that the proximate reason for why eusocial insects can decouple this trade-off is that they have evolved a different 'wiring' of the IIS-JH-Vg/YP circuit. PMID- 27720043 TI - Why do social insect queens live so long? Approaches to unravel the sociality aging puzzle. AB - Social insects are characterized by an apparent reshaping of the fecundity/longevity trade-off with sociality. Currently, we have only sketchy information about the potential underlying causes and mechanisms of aging and senescence which in addition are restricted to few model insect organisms (mainly the fruit fly Drosophila melanogaster and the honey bee Apis mellifera). How can we gain a more thorough understanding how sociality shapes senescence and the fecundity/longevity trade-off? By reviewing available literature, I propose a comparative approach that offers the opportunity to gain fundamental insights into uncovering the basis for this life history trade-off and its reshaping with sociality. PMID- 27720044 TI - Temperature-dependent effects on the replication and transmission of arthropod borne viruses in their insect hosts. AB - The transmissibility of vector borne viruses can be affected by a combination of factors, both extrinsic (climatic changes, temperature, urbanization, among others) and intrinsic (genetics, life span, immunity, among others). Temperature is of particular importance since the insect vectors of arthropod-borne viruses (arboviruses) are ectothermic and acutely susceptible to temperature changes. Modeling suggests that with increasing global temperature and urbanization, arboviral diseases will continue to emerge or reemerge. This review highlights current literature regarding temperature-dependent effects on virus-vector interactions and their potential to influence the transmission dynamics and epidemiology of arboviral diseases. PMID- 27720046 TI - The male has done his work - the male may go. AB - Perennial social insects are famous for the extraordinary longevity of their queens. While the lifespan of termite kings matches those of queens, males of social Hymenoptera are usually considered to die after one or a few copulations. While this is true in species with highly synchronized nuptial flights, in others males mate over much longer periods. Male longevity is not correlated with the life span of queens but appears to be adapted to mating opportunities. This is demonstrated by the extreme life span of Cardiocondyla ant males, which monopolize mating with virgin queens over many months. Cardiocondyla offers the opportunity to investigate why male longevity varies even among closely related taxa and how male age affects sperm and offspring quality. PMID- 27720047 TI - Patterns of longevity across a sociality gradient in vespid wasps. AB - The reversal of the fecundity/longevity tradeoff in social insects is striking, but we lack understanding of when and how this reversal evolved. Vespid wasps are excellent models for studying social evolution because species show different levels of sociality from solitary to primitively to advanced eusocial. We provide the first synthesis of existing, but scanty, data available on longevity in vespids. We explore whether the fecundity/longevity tradeoff reversal is exaggerated in species with more derived sociality. Although the reversal is evident in primitively social wasps, the available data suggest it may be stronger in large-colonied species, which show a trend toward shorter worker longevity. More data are needed on additional species and underlying mechanisms, but vespids hold promise for understanding the evolution of the fecundity/longevity tradeoff reversal. PMID- 27720045 TI - Abiotic and biotic factors affecting the replication and pathogenicity of bee viruses. AB - Bees are important pollinators of plants in both agricultural and non agricultural landscapes. Recent losses of both managed and wild bee species have negative impacts on crop production and ecosystem diversity. Therefore, in order to mitigate bee losses, it is important to identify the factors most responsible. Multiple factors including pathogens, agrochemical exposure, lack of quality forage, and reduced habitat affect bee health. Pathogen prevalence is one factor that has been associated with colony losses. Numerous pathogens infect bees including fungi, protists, bacteria, and viruses, the majority of which are RNA viruses including several that infect multiple bee species. RNA viruses readily infect bees, yet there is limited understanding of their impacts on bee health, particularly in the context of other stressors. Herein we review the influence environmental factors have on the replication and pathogenicity of bee viruses and identify research areas that require further investigation. PMID- 27720048 TI - Manipulation of hosts and vectors by plant viruses and impact of the environment. AB - The effect of environmental factors on the efficiency of plant virus transmission is extremely difficult to predict, because they obviously impact concomitantly multiple steps of the complex three-way plant-virus-vector interaction. This review summarizes the diversity of the relationship between plants, viruses and insect vectors, and highlights the numerous phases of this process that can be altered by the virus in ways that can potentially enhance its transmission success. Many of the reported cases are often considered to be possible viral manipulations acting through modifications of the physiology of the host plant, indirectly reaching to the insect vector. Plants are extremely responsive to environmental fluctuations and so interferences with these putative viral manipulations are highly expected. The role of environmental factors in plant virus transmission can thus be envisaged solely in the context of this complexity. It is only briefly evoked here because this field of research is in its infancy and currently suffers from an impressive lack of experimental data.

Therapeutic strategies to treat or prevent diseases transmitted by the arthropods are limiting. Understanding the role of arthropod gut receptors in the interactions with various arboviruses would provide important means for the development of a strong anti-vector vaccine. In this review, we summarize some of the potential findings in the field of arthropod gut receptors for tick-borne or mosquito-borne viruses and discuss their relevance in the development of a broad spectrum transmission-blocking vaccine to treat or control various diseases caused by arboviruses. PMID- 27720050 TI - Life history evolution in social insects: a female perspective. AB - Social insects are known for their unusual life histories with fecund, long-lived queens and sterile, short-lived workers. We review ultimate factors underlying variation in life history strategies in female social insects, whose social life reshapes common trade-offs, such as the one between fecundity and longevity. Interspecific life history variation is associated with colony size, mediated by changes in division of labour and extrinsic mortality. In addition to the ratio of juvenile to adult mortality, social factors such as queen number influence life history trajectories. We discuss two hypotheses explaining why queen fecundity and lifespan is higher in single-queen societies and suggest further research directions on the evolution of life history variation in social insects. PMID- 27720051 TI - Fitness and aging in Cardiocondyla obscurior ant queens. AB - Easy maintenance, controlled mating and short generation time make Cardiocondyla obscurior an interesting model for social insect aging research. Using this ant we have begun to study the proximate genomic relationship between mating and aging. Although mating in general has a positive effect and results in fertile queens with long life but drastically reduced metabolic rates, mating can also dramatically reduce queen fitness. Here we review a decade of research on factors affecting queen aging rate and contrast these findings with studies on honeybees and solitary aging models. We conclude by giving a brief outlook of what is to be expected from this model in coming years. PMID- 27720053 TI - A critical look at proximate causes of social insect senescence: damage accumulation or hyperfunction? AB - Social insects have received attention for their extreme lifespan variation and reversal of the fecundity/longevity trade-off. However, proximate causes of senescence in general are disputed, and social insects often fail to meet the predictions of prevailing models. We present evidence for and against the long held free radical theory of aging in social insects, and consider the application of the competing hyperfunction theory. Current results present problems for both theories, and a more complex picture of the biological processes involved emerges. The eusocial life style might allow colonies to allocate damage in ways that create seemingly senescence-free life histories. Only experimental approaches characterizing multiple senescence factors simultaneously will shed light on how social insects defy the conventions of senescence. PMID- 27720052 TI - Ties between ageing plasticity and reproductive physiology in honey bees (Apis mellifera) reveal a positive relation between fecundity and longevity as consequence of advanced social evolution. AB - Honey bees (Apis mellifera) are the best studied model of ageing among the social insects. As in other social insects, the reproductive queen far outlives her non reproductive workers despite developing from the same genome in the same colony environment. Thus, the different social roles of the two female castes are critical for the profound phenotypic plasticity. In several special cases, such as the reproductive workers of Apis mellifera capensis, within-caste plasticity enables further studies of the fecundity-longevity syndrome in honey bees. At present, molecular evidence suggests that a reorganization of physiological control pathways may facilitate longevity of reproductive individuals. However, the social role and social environment of the different colony members are also very important and one of the key future questions is how much social facilitation versus internal regulation is responsible for the positive association between fecundity and longevity in honey bees. PMID- 27720054 TI - Lifespan divergence between social insect castes: challenges and opportunities for evolutionary theories of aging. AB - The extraordinarily long lifespans of queens (and kings) in eusocial insects and the strikingly large differences in life expectancy between workers and queens challenge our understanding of the evolution of aging and provide unique opportunities for studying the causes underlying adaptive variation in lifespan within species. Here we review the major evolutionary theories of aging, focusing on their scope and limitations when applied to social insects. We show that reproductive division of labor, interactions between kin, caste-specific gene regulation networks, and the integration of colony-level trade-offs with individual-level trade-offs provide challenges to the classical theories We briefly indicate how these challenges could be met in future models of adaptive phenotypic plasticity in lifespan between and within different castes. PMID- 27720055 TI - Evolutionary origin of pathogenic arthropod-borne viruses-a case study in the family Bunyaviridae. AB - Arthropod-borne viruses have a dual-host tropism and their transmission requires the infection of two disparate hosts, arthropods and vertebrates. Arboviruses occur in several RNA families that also contain viruses with a monotropism for either arthropods or vertebrates. The evolutionary origin of the dual-host tropism of arboviruses was recently identified for the family Bunyaviridae. Bunyaviruses were suggested to have evolved from viruses that are restricted to arthropods as hosts (arthropod-specific viruses). Additional findings of an immense genetic diversity of bunyaviruses in non-blood feeding arthropods support the hypothesis of an arthropod origin of vertebrate-pathogenic bunyaviruses. PMID- 27720056 TI - Chapter 6. Comparative genomic approaches to investigate molecular traits specific to social insects. AB - Ageing is a feature of nearly all known organisms and, by its connection to survival, appears to trade off with fecundity. However, in some organisms such as in queens of social insects, this negative relation appears reversed and individuals live long and reproduce much. Since new experimental techniques, transcriptomes and genomes of many social insects have recently become available, a comparison of these data in a phylogenetic framework becomes feasible. This allows the study of general trends, species specific oddities and evolutionary dynamics of the molecular properties and changes which underlie ageing, fecundity and the reversal of this negative association. In the framework of social insect evolution, we review the most important recent insights, computational methods, their applications and data resources which are available. PMID- 27720057 TI - Viral receptors of the gut: insect-borne propagative plant viruses of agricultural importance. AB - Insect-borne propagative plant viruses of agricultural importance are transmitted by sap-sucking insects. Although the infection routes of these viruses within the bodies of insect vectors are well established, cellular receptors on the microvilli, intercellular junctions, and basal lamina for mediating viral entry or spread in insect gut epithelium have not been well identified or characterized. Recent trends in the field are opening questions on how viruses exploit actin-based tubule motility to overcome insect gut epithelium barriers after viral entry in epithelium. Advances in insect cell lines, genome sequencing, reverse genetic systems and others not yet developed technologies are needed to find and characterize the counterpart receptors in vectors and to design strategies to interfere with viral transmission. PMID- 27720058 TI - Facultative social insects can provide insights into the reversal of the longevity/fecundity trade-off across the eusocial insects. AB - In eusocial insects, reversal of the fecundity/longevity trade-off and extreme differences in life histories between castes of the same species garner scientific and public interest. Facultative social species at the threshold of sociality, in which individuals are socially plastic, provide an excellent opportunity to understand the causes and mechanisms underlying this reversal in life history trade-off associated with eusociality. We briefly present the ultimate factors favoring sociality and the association between fecundity and longevity in facultative eusocial insects, including kin selection and disposable soma, as well as proximate mechanisms observed in such species, such as differences in hormone titers and functions. Potential genetic underpinnings of lifespan and fecundity differences between castes are discussed and future research directions are proposed.

AB - In Latin America, women account for more than 30% of all HIV cases. However, minimal research has been reported on women's beliefs about HIV in Latin America. The purpose of our qualitative study was to describe HIV beliefs in a sample of low-income Nicaraguan women living in a squatter settlement in Managua. Participants (N = 34) were women who participated in four focus groups. The mean age of the women was 40 years, and the mean education level was 5 years. Women reported a plurality of beliefs about HIV, some of which were biomedically accurate while others were not. Themes of stigma and rejection emerged across all focus group discussions. Younger women were more informed than older women. The findings are instructive for nurses working with Nicaraguan women and may be useful in developing HIV education interventions with similar populations in other Latin American countries or with immigrants from those countries. PMID- 27720065 TI - Morning blood pressure surge and markers of cardiovascular alterations in untreated middle-aged hypertensive subjects. AB - The purpose of the study was to evaluate the degree of morning blood pressure surge (MBPS) and its relationship with markers of cardiovascular alterations in untreated middle-aged hypertensives. We studied 241 patients (mean age, 36.6 +/- 10.7 years). Subjects with higher sleep-through MBPS (st-MBPS) were older (P = .003), had higher carotid intima-media thickness (cIMT) (P = .05) and lower E/A ratio (P = .01) than those with lower MBPS. Subjects with higher prewakening MBPS (pw-MBPS) had significantly higher deceleration time (P = .01) compared with those with lower pw-MBPS. St-MBPS correlated significantly with age, cIMT values, 24-hour systolic and diastolic BP, and systolic BP night-time fall. The significant correlations between pw-MBPS and cIMT values, deceleration time, 24 hour diastolic BP and systolic BP night-time fall were observed. A relationship between MBPS and cardiovascular alterations was observed both in dippers and nondippers, although in non-dippers, it was less pronounced. The results may imply a possible link between MBPS and markers of cardiovascular alterations in untreated hypertensive subjects. PMID- 27720066 TI - Effect of visit-to-visit blood pressure variability on cardiovascular events in patients with coronary artery disease and well-controlled blood pressure. AB - This post hoc analysis of CAMELOT and PREVENT analyzed the impact of blood pressure variability (BPV, assessed as within-subject standard deviation of SBP from 12 weeks onward) on the incidence of major adverse cardiovascular events (MACE, defined according to original studies). Patients (n = 1677 CAMELOT; n = 776 PREVENT) were stratified by BPV quartile. Regardless of study, BPV was significantly lower for amlodipine versus other treatments. In CAMELOT, a significant association between BPV quartile and MACE was observed with amlodipine treatment. Significant associations between BPV quartile and MACE were observed for both studies, when analyzed overall (adjusting for treatment). In CAMELOT, with amlodipine treatment, an increased risk for MACE was observed with high (BPV >= Q3) versus low BPV (< Q1; adjusting for characteristics and risk factors). In both studies, increased risk for MACE was observed for BPV >= Q3 versus BPV < Q1 (analyzed overall, adjusting for treatment and covariates). For both studies, BPV, but not mean SBP, was associated with cardiovascular events. BPV was associated with cardiovascular outcomes in patients with CAD and well controlled BP. PMID- 27720067 TI - Cuticle formation and pigmentation in beetles. AB - Adult beetles (Coleoptera) are covered primarily by a hard exoskeleton or cuticle. For example, the beetle elytron is a cuticle-rich highly modified forewing structure that shields the underlying hindwing and dorsal body surface from a variety of harmful environmental factors by acting as an armor plate. The elytron comes in a variety of colors and shapes depending on the coleopteran species. As in many other insect species, the cuticular tanning pathway begins with tyrosine and is responsible for production of a variety of melanin-like and other types of pigments. Tanning metabolism involves quinones and quinone methides, which also act as protein cross-linking agents for cuticle sclerotization. Electron microscopic analyses of rigid cuticles of the red flour beetle, Tribolium castaneum, have revealed not only numerous horizontal chitin protein laminae but also vertically oriented columnar structures called pore canal fibers. This structural architecture together with tyrosine metabolism for cuticle tanning is likely to contribute to the rigidity and coloration of the beetle exoskeleton. PMID- 27720068 TI - The mechanism controlling phenotypic plasticity of body color in the desert locust: some recent progress. AB - Schistocerca gregaria exhibits density-dependent body color polyphenism. Nymphs occurring at low population densities show green-brown polyphenism. They show phase polyphenism and develop black patterns at high population densities. Recent studies suggest a third type of polyphensim, that is, homochromy, a response to background color. Laboratory experiments that considered homochromy suggest that humidity is not directly involved in green-brown polyphenism and that odor from other individuals does not induce black patterns. Black patterns can be induced in isolated nymphs by video images of locusts and tadpoles. Juvenile hormone and [His7]-corazonin control body color in locusts. The gene encoding the latter has been identified for S. gregaria and Locusta migratoria, and its key role in controlling black patterning has been demonstrated. PMID- 27720070 TI - Genes controlling mimetic colour pattern variation in butterflies. AB - Butterfly wing patterns are made up of arrays of coloured scales. There are two genera in which within-species variation in wing patterning is common and has been investigated at the molecular level, Heliconius and Papilio. Both of these species have mimetic relationships with other butterfly species that increase their protection from predators. Heliconius have a 'tool-kit' of five genetic loci that control colour pattern, three of which have been identified at the gene level, and which have been repeatedly used to modify colour pattern by different species in the genus. By contrast, the three Papilio species that have been investigated each have different genetic mechanisms controlling their polymorphic wing patterns. PMID- 27720069 TI - Functional analysis of genes involved in color pattern formation in Lepidoptera. AB - In addition to the genome editing technology, novel functional analyses using electroporation are powerful tools to reveal the gene function in the color pattern formation. Using these methods, several genes involved in various larval color pattern formation are clarified in the silkworm Bombyx mori and some Papilio species. Furthermore, the coloration pattern mechanism underlying the longtime mystery of female-limited Batesian mimicry of Papilio polytes has been recently revealed. This review presents the recent progress on the molecular mechanisms and evolutionary process of coloration patterns contributing to various mimicry in Lepidoptera, especially focusing on the gene function in the silkworm and Papilio species. PMID- 27720071 TI - Color vision and color formation in dragonflies. AB - Dragonflies including damselflies are colorful and large-eyed insects, which show remarkable sexual dimorphism, color transition, and color polymorphism. Recent comprehensive visual transcriptomics has unveiled an extraordinary diversity of opsin genes within the lineage of dragonflies. These opsin genes are differentially expressed between aquatic larvae and terrestrial adults, as well as between dorsal and ventral regions of adult compound eyes. Recent topics of color formation in dragonflies are also outlined. Non-iridescent blue color is caused by coherent light scattering from the quasiordered nanostructures, whereas iridescent color is produced by multilayer structures. Wrinkles or wax crystals sometimes enhances multilayer structural colors. Sex-specific and stage-specific color differences in red dragonflies is attributed to redox states of ommochrome pigments. PMID- 27720072 TI - Molecular mechanisms of secondary sexual trait development in insects. AB - Secondary sexual traits are those traits other than the primary gametes that distinguish the sexes of a species. The development of secondary sexual traits occurs when sexually dimorphic factors, that is, molecules differentially produced by primary sex determination systems in males and females, are integrated into the gene regulatory networks responsible for sexual trait development. In insects, these molecular asymmetric factors were always considered to originate inside the trait-building cells, but recent work points to external factors, such as hormones, as potential candidates mediating secondary sexual trait development. Here, we review examples of the different molecular mechanisms producing sexually dimorphic traits in insects, and suggest a need to revise our understanding of secondary sexual trait development within the insect lineage. PMID- 27720073 TI - Complex responses of insect phenology to climate change. AB - Insect phenologies are changing in response to climate warming. Shifts toward earlier seasonal activity are widespread; however, responses of insect phenology to warming are often more complex. Many species have prolonged their activity periods; others have shown delays. Furthermore, because of interspecific differences in temperature sensitivity, warming can increase or decrease synchronization between insects and their food plants and natural enemies. Here, I review recent findings in three areas-shifts in phenology, changes in voltinism, and altered species interactions-and highlight counterintuitive responses to warming caused by the particularities of insect life cycles. Throughout, I emphasize how an appreciation of the evolutionary processes shaping insect life histories is necessary to forecast changes in insect phenology and their demographic consequences. PMID- 27720074 TI - Can we predict the effects of multiple stressors on insects in a changing climate? AB - The responses of insects to climate change will depend on their responses to abiotic and biotic stressors in combination. We surveyed the literature, and although synergistic stressor interactions appear common among insects, the thin taxonomic spread of existing data means that more multi-stressor studies and new approaches are needed. We need to move beyond descriptions of the effects of multiple stressors to a mechanistic, predictive understanding. Further, we must identify which stressor interactions, and species' responses to them, are sufficiently generalizable (i.e. most or all species respond similarly to the same stressor combination), and thus predictable (for new combinations of stressors, or stressors acting via known mechanisms). We discuss experimental approaches that could facilitate this shift toward predictive understanding. PMID- 27720075 TI - The use of occurrence data to predict the effects of climate change on insects. AB - Experimental information on the roles played by climatic factors in determining the ecology and distribution of insect species is scarce. This has stimulated the increasing use of the climatic characteristics of the localities in which the species are observed to derive predictions under different climatic scenarios (the so called species-distribution models or SDMs). This text reviews the main limitations of these correlative models when they are applied to organisms, such as insects, that are characterized by a high degree of collector bias and incompleteness. It is argued that SDMs must rely solely on presence information, rejecting the use of background or pseudoabsences, and that we are not predicting the future distribution of a species but exploring the future location of the climatic conditions in which a species was observed. The scarcity and bias of the available occurrence information in insects as well as our ignorance about the non-climatic factors delimiting species ranges forces us to be extremely careful. It is therefore desirable to avoid the use of central tendency measures reflecting supposed optimum niche conditions because they are particularly dependent on the quantity and biases of the occurrence information. The use of simple algorithms and procedures aimed at extracting information on environmental limits from the available occurrences would be more convenient in this case. PMID- 27720076 TI - The fingerprints of global climate change on insect populations. AB - Synthesizing papers from the last two years, I examined generalizations about the fingerprints of climate change on insects' population dynamics and phenology. Recent work shows that populations can differ in response to changes in climate means and variances. The part of the thermal niche occupied by an insect population, voltinism, plasticity and adaptation to weather perturbations, and interactions with other species can all exacerbate or mitigate responses to climate change. Likewise, land use change or agricultural practices can affect responses to climate change. Nonetheless, our knowledge of effects of climate change is still biased by organism and geographic region, and to some extent by scale of climate parameter. PMID- 27720077 TI - Molecular basis and ecological relevance of aphid body colors. AB - Aphids are small phloem sap-feeding insects, and show color polymorphism even within the same species. Crossing experiments have revealed the inheritance pattern of the body color. Coloration of aphids is determined by mainly three pigments, melanin, carotenoid, and aphin, and is influenced by both abiotic and biotic environmental factors. Aphid body colors also seem to correspond with specific biological functions under various environments. Partly due to the presence of natural enemies in the environment, a variety of physiological and behavioral responses have evolved in each color form. Thus, predation is one of the most significant external factors for maintaining body color polymorphisms. In addition, endosymbiont infections also influence aphid body color and prey predator interactions. However, many unsolved questions remain regarding the molecular basis for and biological functions of aphid body colors. Further work, including the development of molecular techniques for comprehensive functional analysis, is needed in these areas. PMID- 27720078 TI - Mechanistic models for predicting insect responses to climate change. AB - Mechanistic models of the impacts of climate change on insects can be seen as very specific hypotheses about the connections between microclimate, ecophysiology and vital rates. These models must adequately capture stage specific responses, carry-over effects between successive stages, and the evolutionary potential of the functional traits involved in complex insect life cycles. Here we highlight key considerations for current approaches to mechanistic modelling of insect responses to climate change. We illustrate these considerations within a general mechanistic framework incorporating the thermodynamic linkages between microclimate and heat, water and nutrient exchange throughout the life-cycle under different climate scenarios. We emphasise how such a holistic perspective will provide increasingly robust insights into how insects adapt and respond to changing climates. PMID- 27720079 TI - Will climate change affect insect pheromonal communication? AB - Understanding how climate change will affect species interactions is a challenge for all branches of ecology. We have only limited understanding of how increasing temperature and atmospheric CO2 and O3 levels will affect pheromone-mediated communication among insects. Based on the existing literature, we suggest that the entire process of pheromonal communication, from production to behavioural response, is likely to be impacted by increases in temperature and modifications to atmospheric CO2 and O3 levels. We argue that insect species relying on long range chemical signals will be most impacted, because these signals will likely suffer from longer exposure to oxidative gases during dispersal. We provide future directions for research programmes investigating the consequences of climate change on insect pheromonal communication. PMID- 27720080 TI - A call to insect scientists: challenges and opportunities of managing insect communities under climate change. AB - As climate change moves insect systems into uncharted territory, more knowledge about insect dynamics and the factors that drive them could enable us to better manage and conserve insect communities. Climate change may also require us to revisit insect management goals and strategies and lead to a new kind of scientific engagement in management decision-making. Here we make five key points about the role of insect science in aiding and crafting management decisions, and we illustrate those points with the monarch butterfly and the Karner blue butterfly, two species undergoing considerable change and facing new management dilemmas. Insect biology has a strong history of engagement in applied problems, and as the impacts of climate change increase, a reimagined ethic of entomology in service of broader society may emerge. We hope to motivate insect biologists to contribute time and effort toward solving the challenges of climate change. PMID- 27720081 TI - Evolutionary and ecological patterns of thermal acclimation capacity in Drosophila: is it important for keeping up with climate change? AB - Phenotypic plasticity of temperature tolerance (thermal acclimation) is often highlighted as an important component of the acute and evolutionary adaptation to temperatures in insects. For this reason, it is often suggested that thermal acclimation ability could be important for buffering the consequences of climate change. Based on data from Drosophila we discuss if and how phenotypic plasticity is likely to mitigate the effects of climate change. We conclude that plasticity of upper thermal limits is small in magnitude, evolves slowly and that acclimation ability is weakly correlated with latitude and environmental heterogeneity. Accordingly plasticity in upper thermal limits is unlikely to effectively buffer effects of global warming for species already close to their upper thermal boundaries.

PMID- 27720088 TI - Association Between Factor V Leiden Mutation, Small for Gestational Age, and Preterm Birth: A Systematic Review and Meta-Analysis. AB - OBJECTIVE: To estimate the association of a maternal factor V Leiden (FVL) mutation with SGA and preterm birth. DATA SOURCES: We performed a search of PubMed, Embase, Scopus, CINAHL, and the Cochrane Library from inception to April 2016 for cohort and case-control studies of women with FVL mutation and associated outcomes of SGA and preterm birth that included a reference group without FVL mutation. Additional studies were identified from reference lists of relevant research and review articles. STUDY SELECTION: Two authors (JKB, AMO) independently examined the abstracts of the potentially eligible studies, and full texts of eligible studies were retrieved for further evaluation. Disagreements were resolved by consensus. We identified 42 studies suitable for inclusion in the meta-analysis. DATA EXTRACTION: Thirty-two studies evaluated SGA, and 18 studies assessed preterm birth. Study quality was assessed using the Newcastle Ottawa Scale. A random effects model with inverse variance weighting was used to calculate pooled ORs and 95% CIs. Subgroup analyses were performed by study design. DATA SYNTHESIS: The overall OR associating FVL mutation with SGA was significant (OR 1.40, 95% CI 1.18 to 1.67). Analysis of 13 cohort studies resulted in an OR of 1.20 (95% CI 1.03 to 1.41), and data from 19 case-control studies yielded an OR of 1.86 (95% CI 1.35 to 2.56). There was no significant association between FVL mutation and preterm birth (OR 1.17, 95% CI 1.00 to 1.37) when all groups were studied, but the association was significant for case control studies alone (OR 1.40, 95% CI 1.05 to 1.86). CONCLUSION: There is an increased risk for SGA in pregnancies complicated by FVL mutation in both cohort and case-control study designs. The risk of preterm birth with FVL mutation is less clear, although there is conflicting evidence from cohort and case-control studies regarding the risk of preterm birth associated with FVL mutation. PMID- 27720089 TI - The Usefulness of the APACHE II Score in Obstetric Critical Care: A Structured Review. AB - OBJECTIVE: To assess the performance of the Acute Physiology and Chronic Health Evaluation II (APACHE II) mortality prediction model in pregnant and recently pregnant women receiving critical care in low-, middle-, and high-income countries during the study period (1985-2015), using a structured literature review. DATA SOURCES: Ovid MEDLINE, Embase, Web of Science, and Evidence-Based Medicine Reviews, searched for articles published between 1985 and 2015. STUDY SELECTION: Twenty-five studies (24 publications), of which two were prospective, were included in the analyses. Ten studies were from high-income countries (HICs), and 15 were from low- and middle-income countries (LMICs). Median study duration and size were six years and 124 women, respectively. DATA SYNTHESIS: ICU admission complicates 0.48% of deliveries, and pregnant and recently pregnant women account for 1.49% of ICU admissions. One quarter were admitted while pregnant, three quarters of these for an obstetric indication and for a median of three days. The median APACHE II score was 10.9, with a median APACHE II predicted mortality of 16.6%. Observed mortality was 4.6%, and the median standardized mortality ratio was 0.36 (interquartile range 0.23 to 0.73). The standardized mortality ratio was < 0.9 in 24 of 25 studies. Women in HICs were more frequently admitted with a medical comorbidity but were less likely to die than were women in LMICs. CONCLUSION: The APACHE II score consistently overestimates mortality risks for pregnant and recently pregnant women receiving critical care, whether they reside in HICs or LMICs. There is a need for a pregnancy-specific outcome prediction model for these women. PMID- 27720090 TI - Sex Ratios Among Births in British Columbia, 2000-2013. AB - OBJECTIVE: Previous studies have reported distorted sex ratios among live births within specific immigrant groups in Canada. We carried out an investigation into sex ratios in British Columbia. METHODS: All stillbirths and live births to residents of British Columbia from April 2000 to March 2013 were included in the study, with data obtained from the British Columbia Perinatal Data Registry. We examined sex ratios among births and among pregnancy terminations that resulted in a stillbirth or live birth. Analyses were stratified by congenital anomaly status, maternal residence, and parity. RESULTS: The study population included 567 225 stillbirths and live births. In the Fraser Health Authority, the sex ratio among births without congenital anomalies was 51.3% males (95% CI 51.1 to 51.5); this was significantly higher than the sex ratio of 40.7% males (95% CI 33.2 to 48.6) among late pregnancy terminations without congenital anomalies (P = 0.008). However, in British Columbia, excluding the Fraser Health Authority, the same sex ratios were 51.1% (95% CI 50.9 to 51.3) and 51.1% (95% CI 45.5 to 56.7), respectively (P = 0.99). Sex ratios among births to multiparous women were also significantly different in the Fraser Health Authority. Only a negligible fraction of the shortfall in female births in the Fraser Health Authority could be explained by sex ratio distortions among late pregnancy terminations. CONCLUSION: Sex ratios among stillbirths and live births to residents of the Fraser Health Authority are distorted relative to those observed elsewhere in British Columbia. This is likely due to sex differences in early pregnancy terminations. PMID- 27720091 TI - Ongoing Cases of Early-Onset Group B Streptococcal Disease in the Era of Screening and Prophylaxis. AB - OBJECTIVE: We reviewed cases of group B Streptococcus (GBS) sepsis in term infants at our institution to identify areas for potential prevention. METHODS: We identified cases by searching our institution's microbiology databases for all positive GBS blood and cerebrospinal fluid cultures taken from infants between 2008 and 2013. Patients were included if the timing of the positive culture met the criteria for early-onset GBS disease (age 7 days or under). Charts that met inclusion criteria were abstracted for details related to antepartum screening, intrapartum care, and postpartum outcome. RESULTS: There are an average of 10 000 deliveries per year in our institution. During the five-year period (2008-2013), we identified 13 cases representing early-onset GBS disease in term infants. Of the 13 cases, nine mothers screened negative for GBS, two screened positive, and two were screened unknown. Four cases qualified for intrapartum prophylaxis; of these, two did not receive appropriate prophylaxis, one because of parental refusal and one for unspecified reasons after the membranes had been ruptured for > 18 hours. All 13 infants had confirmed GBS bacteremia, and four had concurrent GBS meningitis. One infant died and one infant had neurologic sequelae. CONCLUSION: Early-onset GBS disease in term infants continues to occur at our institution, and consequences for the infant can be severe. The majority of cases identified were screened and managed in accordance with current guidelines. Most cases were GBS negative when screened in the antepartum period, raising the question of whether a more sensitive test or a test closer to delivery could prevent further cases of early-onset GBS disease. PMID- 27720092 TI - Evaluating the Postpartum Maternal Health Clinic: How Patient Characteristics Predict Follow-Up. AB - OBJECTIVE: At Kingston General Hospital, women who have pregnancy-related cardiovascular risk indicators (e.g., preeclampsia, gestational hypertension, gestational diabetes) are offered standardized six-month postpartum follow-up for cardiovascular disease risk screening and counselling. We sought to assess how patient characteristics predict attendance at follow-up. METHODS: We undertook a chart review of 650 patients who delivered between April 2011 and December 2014 and had preeclampsia, gestational hypertension, or gestational diabetes. Logistic regression was used to analyze the relationship between clinical and demographic variables and attendance at the follow-up clinic. RESULTS: Increasing age (in years) was significantly correlated with attendance at follow-up (adjusted OR [aOR] 1.08, 95% CI 1.04 to 1.12). Women who had preeclampsia were significantly more likely to attend than women who had gestational hypertension or gestational diabetes (aOR 1.54, 95% CI 1.05 to 2.26). Women who were known to be non-smokers or whose smoking status was not recorded were significantly more likely to attend follow-up (aOR 2.47, 95% CI 1.32 to 4.62). There was a trend towards lower follow up for women from census tracts or subdivisions with a greater proportion of individuals without educational certificate, diploma, or degree, but this was not statistically significant (aOR 0.10, 95% CI 0.01 to 1.22). CONCLUSION: There is significant selection bias among women who attend follow-up for postpartum cardiovascular disease risk screening and counselling after pregnancies complicated by preeclampsia, gestational hypertension, or gestational diabetes. PMID- 27720093 TI - Magnocaine: Physical Compatibility and Chemical Stability of Magnesium Sulphate and Lidocaine Hydrochloride in Prefilled Syringes. AB - OBJECTIVE: To evaluate the physical compatibility and chemical stability of mixtures of magnesium sulphate and lidocaine in order to determine the feasibility of manufacturing a prefilled syringe combining these two drugs for use as an intramuscular (IM) loading dose for eclampsia prevention and/or treatment. This ready-to-use mixture will provide a more tolerable and accessible route of administration appropriate for widespread use. METHODS: Physical compatibility (pH, colour, and formation of precipitate) and chemical stability (maintaining > 90% of initial concentrations) of mixtures of MgSO4, using both commercially available MgSO4 (50%) and MgSO4 reconstituted from salt (61%), with lidocaine hydrochloride (2%) were evaluated every 14 days over six months. The concentration of lidocaine was determined by a stability indicating high performance liquid chromatographic method, while the concentration of magnesium was determined by an automated chemistry analyzer. RESULTS: No changes in pH, color or precipitates were observed for up to 6 months. The 95% confidence interval of the slope of the curve relating concentration to time, determined by linear regression, indicated that only the admixtures of commercially-available magnesium sulfate and lidocaine as well as the 61% magnesium sulfate solution (reconstituted from salt) maintained at least 90% of the initial concentration of both drugs at 25 degrees C and 40 degrees C at 6 months. CONCLUSIONS: Commercially available MgSO4 and lidocaine hydrochloride, when combined, are stable in a pre-filled syringe for at least six months in high heat and humidity conditions. This finding represents the first step in improving the administration of magnesium sulphate in the treatment and prevention of eclampsia in under-resourced settings. PMID- 27720094 TI - Optimizing Participation of Pregnant Women in Clinical Trials: Factors Influencing Decisions About Participation in Medication and Vaccine Trials. AB - OBJECTIVE: To obtain information on women's attitudes and opinions about participation in vaccine and medication trials during pregnancy. METHODS: A quantitative, cross-sectional survey was administered to 110 consenting women over a four-week period in the waiting room of an ambulatory obstetrics and gynaecology clinic in Ontario. RESULTS: The final response rate was 74.8%, with the majority of participants agreeing with statements about the importance of obtaining safety data about products in pregnancy and the importance of a woman having the ability to choose whether to participate in such research. Of all participants, 16.3% indicated they would consider participating in vaccine research during pregnancy and 20.0% would consider participating in medication research during pregnancy. Factors relating to maternal or fetal/child health were the most frequently cited factors influencing willingness to participate, with lack of trust in researchers and pharmaceutical companies as factors that would discourage participation. CONCLUSION: A minority of pregnant women were willing to consider participating in medication or vaccine research during pregnancy. Optimizing participation requires providing women (and if appropriate, their partners) with detailed, multidisciplinary education about the maternal and fetal benefits and risks of such trials. Education about the principles of research ethics, including the limits of involvement of pharmaceutical companies, would be beneficial. PMID- 27720095 TI - Uterine Transplants in the Canadian Setting: A Theoretical Framework. AB - The uterine transplant is an innovative surgical procedure whereby a healthy uterus is transplanted into a woman with uterine factor infertility (UFI) for the purpose of procreation. Twelve uterine transplants have been attempted in the world in the last two decades, and five have led to viable births. While uterine transplantation is still in its experimental stages, it remains unclear whether Canadian centres plan to attempt the procedure in the near future. Herein, I raise several observations that are specific to the Canadian setting and apply the Montreal Criteria for the Ethical Feasibility of Uterine Transplantation to determine whether there is fertile ground for a uterine transplantation program to be adopted in Canada. PMID- 27720096 TI - Improving Communication in Obstetrics Practice. PMID- 27720097 TI - Implications of Applying Minimal Risk Standards in Clinical Research to Information Provision in Prenatal and Pre-conception Care. AB - BACKGROUND: There have long been minimal risk thresholds beneath which risks may not need to be discussed in clinical research. This threshold concept may be applied to clinical practice. Our research explored application of minimal risk standards in research regulations to providing information in prenatal and pre conception care. METHODS: A case study approach applied minimal risk standards in research regulations to prenatal and pre-conception care with respect to the risks of excess alcohol consumption, folic acid insufficiency, exposure to phthalate plasticizers, and exposure to brominated flame retardants (BFRs). RESULTS: Excess alcohol consumption and folic acid insufficiency were found to be above the minimal risk standards as outlined in research regulations, while exposure to phthalates and BFRs requires more evidence to determine whether they are above minimal risk. However, applying the minimal risk standard based on the daily life of a healthy adult or a fetus in a healthy pregnant woman, phthalates and BFRs are at the minimal risk threshold regardless of their potential harm since all pregnant women may be exposed to these chemicals in their daily life. Nevertheless, if there is demonstration of sufficient evidence of harm, they may be above minimal risk if such harm can be reduced by individual choice to avoid exposure. CONCLUSION: The minimal risk concept in research regulations as applied to clinical practice may be useful to help clinicians and professional organizations determine what risks need be discussed in prenatal and pre conception care. PMID- 27720098 TI - Contrast enhanced ultrasound (CEUS) in the prenatal evaluation of suspected invasive placenta percreta. AB - BACKGROUND: Morbidly adherent placentation now complicates approximately 1 in 500 pregnancies. Our group and others have demonstrated that antenatal diagnosis of invasive placentation and team-based delivery reduce severe morbidity. Ultrasound and magnetic resonance imaging (MRI) are both employed in the antenatal evaluation of pregnancies with suspected placenta increta/percreta. Accurate diagnosis in this context is essential to direct resources appropriately. Ultrasound methods, including colour and power Doppler, are the mainstays of screening at-risk women, whereas MRI is reserved for diagnostic purposes because of its cost and limited accessibility. In current practice, both methods are significantly limited by an inability to accurately define aberrant utero placental blood flow, the definitive sign of deeply invasive placentation. We describe here an adjunctive method to define aberrant blood flow using ultrasound. CASE: We employed contrast-enhanced ultrasound (CEUS) in the antenatal evaluation of suspected extensive invasive placentation in a woman at 18 weeks' gestation. Invasive placentation was confirmed following hysterectomy. CONCLUSION: CEUS, a technique that has been established as safe and well tolerated in the non-pregnant setting, has the potential to be deployed as a powerful adjunct to ultrasound to enhance both the screening and diagnostic components of care for women with suspected invasive placentation. PMID- 27720099 TI - Isolated Appendiceal Endometriosis. AB - BACKGROUND: Pain associated with appendiceal endometriosis can mimic other intra abdominal pathology. The diagnosis is usually obvious during gross inspection of the appendix; however, the absence of classical macroscopic appearances may lead to missed cases in which the patient's pain is misdiagnosed and inappropriately managed. CASE: A 34-year-old woman presented with cyclical right iliac fossa pain and an elevated serum C-reactive protein of 13 mg/L (normal < 5 mg/L). Diagnostic laparoscopy showed an isolated appendiceal mass with no pelvic endometriosis, and an appendectomy was performed. Histopathology demonstrated appendiceal endometriosis without macroscopic involvement of other pelvic organs. CONCLUSION: This case gives insight into the pathophysiology of endometriosis. We advocate routine appendectomy in women with unexplained recurrent abdominal pain because a diagnostic laparoscopy may miss isolated endometriosis of the appendix, and we now have evidence that this may have no external features suggesting the diagnosis. Additionally, endometriosis can involve the gastrointestinal tract without involvement of the reproductive organs. This is important information in the further progression of theories underlying the pathophysiology of endometriosis. PMID- 27720100 TI - Ultrasound Evaluation of First Trimester Complications of Pregnancy. AB - OBJECTIVE: OUTCOMES:: EVIDENCE: A MEDLINE search and review of bibliographies identified articles was conducted. VALUES: The evidence collected was reviewed by the Diagnostic Imaging Committee of the Society of Obstetricians and Gynaecologists of Canada. The recommendations were made according to the guidelines developed by The Canadian Task Force on Preventive Health Care (Table 1). BENEFITS, HARMS, AND COSTS: Women presenting with first trimester bleeding may be incorrectly diagnosed with a missed abortion, may have an ectopic pregnancy overlooked, or may be inappropriately reassured about viability. Improvement in the identification of the sonographic landmarks of normal embryonic development and awareness of the sonographic risk factors of pregnancy failure may lead to more case-specific management strategies. Diagnosis of suspected ectopic pregnancy often involves an assessment of both hormonal markers and sonographic features. Maternal morbidity and mortality can be reduced with an early diagnosis of ectopic pregnancy.

AB - OBJECTIFS: ReSULTATS: SOURCES DE DONNeES: Nous avons effectue des recherches dans MEDLINE et un examen de la bibliographie des articles recenses. VALEURS: Le Comite d'imagerie diagnostique de la Societe des obstetriciens et gynecologues du Canada a passe en revue les donnees probantes recueillies. Les recommandations reposent sur les lignes directrices elaborees par le Groupe d'etude canadien sur les soins de sante preventifs (tableau 1). AVANTAGES, DeSAVANTAGES ET COuTS: Les femmes qui presentent des saignements durant le premier trimestre peuvent recevoir un diagnostic incorrect d'avortement manque. En outre, on risque de ne pas detecter une grossesse ectopique ou de les rassurer a tort sur la viabilite de l'embryon. L'amelioration de la detection des reperes echographiques du developpement embryonnaire normal et de la connaissance des facteurs de risque lies a l'echec de grossesse sur le plan echographique pourrait donner lieu a l'elaboration de strategies de prise en charge mieux adaptees a chaque cas. Le diagnostic d'une grossesse ectopique suspectee repose souvent sur l'evaluation de marqueurs hormonaux et de caracteristiques echographiques. Par ailleurs, le diagnostic precoce de grossesse ectopique peut reduire la morbidite et la mortalite maternelles. RECOMMANDATIONS.

AB - OBJECTIVE: Picture books may facilitate parents' efforts to decrease pickiness and other undesirable food habits in children. This study conducted a content analysis of dietary behaviors and feeding strategies featured in fictional picture books compared with those discussed in the research literature. DESIGN: Several databases were searched for fictional picture books about dietary behavior, published between 2000 and 2016, accessible in the US, available in print format, and designated for 4- to 8-year-olds. PHENOMENON OF INTEREST: Messages about dietary behavior in picture book fiction. ANALYSIS: Stories were systematically coded using holistic, data-driven, and evaluation coding methods. The final set of codes was examined for themes and patterns. RESULTS: Of the 104 books, 50% featured a specific eating behavior, 21% lifestyle/eating patterns, 20% food-related sensations and emotions, and 9% table manners. CONCLUSIONS AND IMPLICATIONS: Books about dietary behaviors are abundant but the topic coverage is unbalanced. Problem behaviors portrayed in books overlap those discussed in the research literature. However, problem-solving strategies and actions do not align with those endorsed by nutrition professionals. Messages vary in their complexity (in terms of their plot and/or language), ranging from clear and direct to vague, sophisticated, unresolved, conflicting, or controversial. Recommendations for practitioners are discussed. PMID- 27720106 TI - Erratum. PMID- 27720105 TI - A Systematic Review of the Impact of Multi-Strategy Nutrition Education Programs on Health and Nutrition of Adolescents. AB - OBJECTIVE: To update evidence on the impact of multi-strategy nutrition education interventions on adolescents' health and nutrition outcomes and behaviors. DESIGN: Systematic review of randomized controlled studies of multi-strategy interventions encompassing nutrition education published from 2000 to 2014 guided by the Preferred Reported Items for Systematic Reviews and Meta-analyses statement. SETTING: Secondary schools in developed countries. PARTICIPANTS: Adolescents aged 10-18 years. MAIN OUTCOME MEASURES: Anthropometric and dietary intake. ANALYSIS: Systematic search of 7,009 unduplicated articles and review of 11 studies (13 articles) meeting inclusion criteria using qualitative comparison. RESULTS: Four studies reported significant changes in anthropometric measures and 9 showed significant changes in dietary intake. Type of nutrition education varied. Components of the interventions that showed statistically significant changes in anthropometric and dietary intake included facilitation of the programs by school staff and teachers, parental involvement, and using theoretical models to guide the intervention's development. Changes in canteens, food supply, and vending machines were associated with significant changes in dietary intake. CONCLUSIONS AND IMPLICATIONS: Multi-strategy interventions can have significant impacts on nutrition of adolescents when the nutrition education is theoretically based and facilitated by school staff in conjunction with parents and families, and includes changes to the school food environment. PMID- 27720107 TI - Nutrition Education Resources in North Carolina-Based Head Start Preschool Programs: Administrator and Teacher Perceptions of Availability and Use. AB - OBJECTIVE: The purpose of this study was to provide new insight into common barriers to the availability and use of nutrition education (NE) resources in Head Start preschool programs based on administrator and teacher perceptions. METHODS: In-depth, semistructured phone interviews (n = 63) were conducted with administrators (n = 31) and teachers (n = 32) from North Carolina-based Head Start programs. Interviews were audio-recorded and transcribed verbatim. Data were analyzed qualitatively using content analysis to identify common themes. RESULTS: Five emergent themes were identified within the areas of NE resource availability and use and barriers to NE resource availability and use. Participants expressed desire for greater organization of existing NE material resources, increased community support, and professional development opportunities for teachers specific to NE. Funding and time constraints were reported as affecting NE resources. CONCLUSIONS AND IMPLICATIONS: Creative strategies for addressing NE resource availability and use and barriers (eg, NE integration with educational standards) in Head Start are needed.

PMID- 27720112 TI - Development of chemical isotope labeling liquid chromatography mass spectrometry for silkworm hemolymph metabolomics. AB - Silkworm (Bombyx mori) is a very useful target insect for evaluation of endocrine disruptor chemicals (EDCs) due to mature breeding techniques, complete endocrine system and broad basic knowledge on developmental biology. Comparative metabolomics of silkworms with and without EDC exposure offers another dimension of studying EDCs. In this work, we report a workflow on metabolomic profiling of silkworm hemolymph based on high-performance chemical isotope labeling (CIL) liquid chromatography mass spectrometry (LC-MS) and demonstrate its application in studying the metabolic changes associated with the pesticide dichlorodiphenyltrichloroethane (DDT) exposure in silkworm. Hemolymph samples were taken from mature silkworms after growing on diet that contained DDT at four different concentrations (1, 0.1, 0.01, 0.001 ppm) as well as on diet without DDT as controls. They were subjected to differential 12C-/13C-dansyl labeling of the amine/phenol submetabolome, LC-UV quantification of the total amount of labeled metabolites for sample normalization, and LC-MS detection and relative quantification of individual metabolites in comparative samples. The total concentration of labeled metabolites did not show any significant change between four DDT-treatment groups and one control group. Multivariate statistical analysis of the metabolome data set showed that there was a distinct metabolomic separation between the five groups. Out of the 2044 detected peak pairs, 338 and 1471 metabolites have been putatively identified against the HMDB database and the EML library, respectively. 65 metabolites were identified by the dansyl library searching based on the accurate mass and retention time. Among the 65 identified metabolites, 33 positive metabolites had changes of greater than 1.20 fold or less than 0.83-fold in one or more groups with p-value of smaller than 0.05. Several useful biomarkers including serine, methionine, tryptophan, asymmetric dimethylarginine, N-Methyl-D-aspartic and tyrosine were identified. The changes of these biomarkers were likely due to the disruption of the endocrine system of silkworm by DDT. This work illustrates that the method of CIL LC-MS is useful to generate quantitative submetabolome profiles from a small volume of silkworm hemolymph with much higher coverage than conventional LC-MS methods, thereby facilitating the discovery of potential metabolite biomarkers related to EDC or other chemical exposure. PMID- 27720113 TI - A dual-response fluorescent probe for Zn2+ and Al3+ detection in aqueous media: pH-dependent selectivity and practical application. AB - A Schiff base-type fluorescent probe (1) consist of 2-hydroxynaphthaldehyde and glutamide moieties has been designed and synthesized for detection Zn2+ and Al3+. The probe shows pH dependent dual-selectivity for Zn2+ and Al3+ in Tris-HCl buffer, viz. that can selectively recognized Zn2+ at pH 7.4 and Al3+ at pH 6.0, respectively. From Job's plots and MS data, the stoichiometric ratios of the probe with Zn2+ and Al3+ appeared to be 1:1 and 2:1, respectively. The probe can detect as low as 5.5 * 10-8 M-1 Zn2+ and 1.27 * 10-7 M-1 Al3+, whereas respective association constants are 4.27 * 104 M-1 and 3.50 * 109 M-1. Furthermore, it is also confirmed that the probe has good cell-permeability and could thus be used to selectively sense intracellular Zn2+ and Al3+ by bioimaging in different pH environment. Finally the probe has been used successfully for determination of the analytes in real drug samples. PMID- 27720114 TI - Synthesizing a nano-composite of BSA-capped Au nanoclusters/graphitic carbon nitride nanosheets as a new fluorescent probe for dopamine detection. AB - A strong red fluorescent nanocomposite, consisting of graphite-like carbon nitride nanosheets (g-C3N4 NSs) and serum albumin-capped Au nanoclusters (AuNCs), was synthesized. Dopamine (DA) can quench the red fluorescence of the nanocomposite, based on the Forster resonance energy transfer (FRET) mechanism. In this quenching process, the energy is transferred from the fluorescent g-C3N4 NSs-AuNCs to the oxidized DA quinine molecules (DA is easily oxidated to form DA quinine in air). The red fluorescence emission at 420 nm decreases dramatically and the quenching ratio (F0 - F)/F0 is linearly related to the concentration of DA in the range of 0.05-8.0 MUmol L-1 with a detection limit of 0.018 MUmol L-1 (S/N = 3). Additionally, this sensor has a potential of application to assay the DA in the real samples, such as human serum and human urine.

AB - This paper is a review of ion chromatographic (IC) separations of inorganic oxyhalide disinfection by-products (DBPs) in water and beverages. The review outlines the chemical mechanisms of formation, regulation of maximum allowable levels, chromatographic column selection and speciation. In addition, this review highlights the application of IC coupled to mass spectrometry (MS) for trace and elemental composition analysis of oxyhalides, along with the analytical considerations associated to enable sensitive analysis. Furthermore, a review of literature concerning IC determination of inorganic oxyhalide DBPs in environmental matrices, including water, published since 2005 is presented, with a focus on MS detection, and a discussion on the relative performance of the methods. Finally some prospective areas for future research, including fast, selective, multi-analyte analysis, for this application are highlighted and discussed. PMID- 27720117 TI - Electrophoretic stacking for sensitive determination of antibiotic ceftazidime in human blood and microdialysates from diabetic foot. AB - An electrophoretic stacking method has been developed for monitoring the therapeutic level of the antibiotic ceftazidime in blood plasma and microdialysates taken from peripheral soft tissues of the lower limbs of patients with diabetic foot syndrome. The biological samples are treated by addition of acetonitrile in an amount of 75% v/v and injected into a capillary in a large volume; after turning on the separation voltage, the residual acetonitrile is forced out of the capillary by the application of hydrodynamic pressure. The clinical samples were separated in an optimised background electrolyte composed of 50 mM chloroacetic acid +20% v/v methanol +0.5% v/v INST coating solution. The attained LOD for ceftazidime equalled 0.42 MUg mL-1 (0.8 MUM) and the migration time equalled 3.75 min when using a 25 MUm capillary with minimum length of 31.5 cm. The separation was controlled by a maximum voltage of +30 kV and the movement of the analyte was accelerated by a pressure of 50 mbar. The RSD values for intra day repeatability of the migration time and peak area are 0.14% and 3.8%, respectively; the inter-day values equalled 0.25% for the migration time and 7.3% for peak area, respectively. Pharmacological studies revealed that ceftazidime passes from the blood circulation to the peripheral tissues of the lower limbs with an efficiency of 20%. The introduction of CE control of ceftazidime level in diabetic foot represents a very important improvement in achieving the targeted therapeutic effect. PMID- 27720116 TI - Multi-residue analysis of pesticides, plant hormones, veterinary drugs and mycotoxins using HILIC chromatography - MS/MS in various food matrices. AB - One of the recent trends in Analytical Chemistry is the development of economic, quick and easy hyphenated methods to be used in a field that includes analytes of different classes and physicochemical properties. In this work a multi-residue method was developed for the simultaneous determination of 28 xenobiotics (polar and hydrophilic) using hydrophilic interaction liquid chromatography technique (HILIC) coupled with triple quadrupole mass spectrometry (LC-MS/MS) technology. The scope of the method includes plant growth regulators (chlormequat, daminozide, diquat, maleic hydrazide, mepiquat, paraquat), pesticides (cyromazine, the metabolite of the fungicide propineb PTU (propylenethiourea), amitrole), various multiclass antibiotics (tetracyclines, sulfonamides quinolones, kasugamycin and mycotoxins (aflatoxin B1, B2, fumonisin B1 and ochratoxin A). Isolation of the analytes from the matrix was achieved with a fast and effective technique. The validation of the multi-residue method was performed at the levels: 10 MUg/kg and 100 MUg/kg in the following representative substrates: fruits-vegetables (apples, apricots, lettuce and onions), cereals and pulses (flour and chickpeas), animal products (milk and meat) and cereal based baby foods. The method was validated taking into consideration EU guidelines and showed acceptable linearity (r >= 0.99), accuracy with recoveries between 70 and 120% and precision with RSD <= 20% for the majority of the analytes studied. For the analytes that presented accuracy and precision values outside the acceptable limits the method still is able to serve as a semi-quantitative method. The matrix effect, the limits of detection and quantification were also estimated and compared with the current EU MRLs (Maximum Residue Levels) and FAO/WHO MLs (Maximum Levels) or CXLs (Codex Maximum Residue Limits). The combined and expanded uncertainty of the method for each analyte per substrate, was also estimated. PMID- 27720118 TI - Titanium dioxide nanoparticle coating of polymethacrylate-based chromatographic monoliths for phosphopetides enrichment. AB - Metal oxide affinity chromatography has been one of the approaches for specific enrichment of phosphopeptides from complex samples, based on specific phosphopeptide adsorption forming bidentate chelates between phosphate anions and the surface of a metal oxide, such as TiO2, ZrO2, Fe2O3, and Al2O3. Due to convective mass transfer, flow-independent resolution and high dynamic binding capacity, monolith chromatographic supports have become important in studies where high resolution and selectivity are required. Here, we report the first synthesis and characterization of immobilisation of rutile TiO2 nanoparticles onto organic monolithic chromatographic support (CIM-OH-TiO2). We demonstrate the specificity of CIM-OH-TiO2 column for enrichment of phosphopeptides by studying chromatographic separation of model phosphorylated and nonphosphorylated peptides as well as proving the phosphopeptide enrichment of digested bovine alpha-casein. The work described here opens the possibility for a faster, more selective enrichment of phosphopeptides from biological samples that will enable future advances in studying protein phosphorylation. PMID- 27720119 TI - Tutorial on estimating the limit of detection using LC-MS analysis, part I: Theoretical review. AB - A large body of literature exists on the limit of detection (LOD), but there is still a lot of confusion about this important validation parameter. This confusion mainly stems from its statistically complex background. The goal of this two-part tutorial is to discuss and clarify the topic of LOD for practitioners. The two main conclusions of this tutorial are: (1) the choice of how to estimate LOD should be based on the purpose of the analytical method that is being validated (e.g. considerable effort should not be made to estimate LOD for a method that is not used for detecting traces in the vicinity of LOD), and (2) LOD estimates are strongly dependent on different assumptions and the approach used, and therefore caution must be exercised when using the estimate or when comparing different estimates. Part I of the tutorial contains a theoretical discussion (without excessively sophisticated statistics) and part II contains examples based on experimental data. In Part I, LOD and other definitions related to it are reviewed, and their estimation and use are discussed. The assumptions and practicality of different approaches to estimate LOD are compared. Different aspects of the analytical method that strongly influence LOD estimates (e.g. linearity, scedasticity and day-to-day variability of LOD) together with experimental design considerations when estimating LOD are discussed. In part II, LOD is estimated for the LC-MS/MS analysis method to detect pesticides on separate days. The performance of different tests on the data necessary for LOD estimation are discussed and the results of different approaches under review in this tutorial are compared. In conclusion, a decision tree is proposed for estimating and monitoring LOD. A detailed working procedure for estimating LOD is presented. Several topics are pointed out in which further research and discussion is needed. PMID- 27720120 TI - Tutorial on estimating the limit of detection using LC-MS analysis, part II: Practical aspects. AB - In part II of this tutorial, the investigated approaches of estimating the limit of detection (LOD) are applied to experimental data from LC-MS measurements. Important practical aspects specific to LC-MS and related to LOD are reviewed. The results of different tests of estimating linearity and scedasticity are compared. LOD estimates obtained with different approaches (for both simple characterization of the analysis method and accurate interpretation of the results) are applied to the data and the obtained values are compared. As a conclusion, a decision tree is proposed for estimating LOD for analytical methods using the LC-MS technique. PMID- 27720121 TI - Rapid quantification of metabolic intermediates in blood by liquid chromatography tandem mass spectrometry to investigate congenital lactic acidosis. AB - A novel liquid chromatography-tandem mass spectrometry (LC-MS/MS) method has been established to quantify metabolic intermediates, including lactate (Lac), pyruvate (Pyr), acetoacetate (ACAC) and 3-hydroxybutyrate (3-HB) in blood. Samples were deproteinized with methanol-acetonitrile solution, and analytes were separated on an adamantyl group-bonded reverse phase column and detected in multiple reaction monitoring mode. Total analysis time was 4 min per sample. Method validation results displayed that limits of quantification were 10.0 MUmol L-1 for Lac and Pyr, and 5.0 MUmol L-1for ACAC and 3-HB. The within- and between run coefficients of variation were in the range of 1.2-6.4% for all analytes. The recoveries were ranged from 95.6 to 111.5%. The reference values of analytes were determined for the pediatric population. Duo to instability of Lac, Pyr and ACAC in vitro, a comprehensive stability assay was performed to determine optimal conditions for sample collection, pretreatment and storage. Results showed that precipitation of protein in blood at bedside combined with low storage temperature could effectively preserve the integrity of Lac, Pyr and 3-HB, but the precipitated protein accelerated degradation of ACAC. Isolation of supernatant fluid slowed degradation of ACAC. Supernatant samples could store at 20 degrees C for 10 days. The use of plasma or serum to determine these intermediates was not recommended. In this study, 450 samples from patients were analyzed, and 7 patients were diagnosed as congenital lactic acidosis. With the advantages of rapid, accurate and reliable, this method is very suitable for congenital lactic acidosis screening and researches related to energy metabolism. PMID- 27720122 TI - Plasma micro-nanotextured polymeric micromixer for DNA purification with high efficiency and dynamic range. AB - We present a polymeric microfluidic chip capable of purifying DNA through solid phase extraction. It is designed to be used as a module of an integrated Lab-on chip platform for pathogen detection, but it can also be used as a stand-alone device. The microfluidic channels are oxygen plasma micro-nanotextured, i.e. randomly roughened in the micro-nano scale, a process creating high surface area as well as high density of carboxyl groups (COOH). The COOH groups together with a buffer that contains polyethylene glycol (PEG), NaCl and ethanol are able to bind DNA on the microchannel surface. The chip design incorporates a mixer so that sample and buffer can be efficiently mixed on chip under continuous flow. DNA is subsequently eluted in water. The chip is able to isolate DNA with high recovery efficiency (96+/- 11%) in an extremely large dynamic range of prepurified Salmonella DNA as well as from Salmonella cell lysates that correspond to a range of 5 to 1.9 * 108 cells (0.263 fg to 2 * 500 ng). The chip was evaluated via absorbance measurements, polymerase chain reaction (PCR), and gel electrophoresis. PMID- 27720123 TI - Colorimetric detection of proteins based on target-induced activation of aptazyme. AB - The detection of protein is vital to fundamental research as well as practical applications. However, most detection methods depend on antibody-based assays which are faced with many shortcomings. Herein, we propose a colorimetric method for protein assays based on target-triggered activation of aptazyme, which may offer simple, rapid and cost-effective detection of the target protein. In this method, the conformation change of aptazyme induced by target protein is designed to be associated with aptazyme activation. Consequently, in the presence of the target protein, the designed DNA linkers will be cleaved into two fragments that fail to cross-link gold nanoparticles (GNPs), thus the color of GNP solution remains red, while the color will be changed in the absence of the target. Because of the advantages of aptazyme such as economic synthesis, stable, easy modification and its ability to accomplish signal recognition and signal amplification simultaneously, the method is thermostable, simple and cost efficient. In this work, we have taken the detection of vascular endothelial growth factor (VEGF) as an example, which can present an analytical performance with as low as 0.1 nM detection limit, spanning a detection range of 3 orders of magnitude. What is more, the principle of this proposed new method can be extended as a universal assay method not only for the detection of analytes which have an aptamer but also for those analytes that have ligands. PMID- 27720124 TI - Enhanced sensing of dengue virus DNA detection using O2 plasma treated-silicon nanowire based electrical biosensor. AB - Dengue Virus (DENV) has become one of the most serious arthropod-borne viral diseases, causing death globally. The existing methods for DENV detection suffer from the late stage treatment due to antibodies-based detection which is feasible only after five days following the onset of the illness. Here, we demonstrated the highly effective molecular electronic based detection utilizing silicon nanowire (SiNW) integrated with standard complementary metal-oxide-semiconductor (CMOS) process as a sensing device for detecting deoxyribonucleic acid (DNA) related to DENV in an early stage diagnosis. To transform the fabricated devices as a functional sensing element, three-step procedure consist of SiNW surface modification, DNA immobilization and DNA hybridization were employed. The detection principle works by detecting the changes in current of SiNW which bridge the source and drain terminal to sense the immobilization of probe DNA and their hybridization with target DNA. The oxygen (O2) plasma was proposed as an effective strategy for increasing the binding amounts of target DNA by modified the SiNW surface. It was found that the detection limit of the optimized O2 plasma treated-SiNW device could be reduced to 1.985 * 10-14 M with a linear detection range of the sequence-specific DNA from 1.0 * 10-9 M to 1.0 * 10-13 M. In addition, the developed biosensor device was able to discriminate between complementary, single mismatch and non-complementary DNA sequences. This highly sensitive assay was then applied to the detection of reverse transcription polymerase chain reaction (RT-PCR) product of DENV-DNA, making it as a potential method for disease diagnosis through electrical biosensor. PMID- 27720125 TI - One-pot synthesis of strongly fluorescent DNA-CuInS2 quantum dots for label-free and ultrasensitive detection of anthrax lethal factor DNA. AB - Herein, high quality DNA-CuInS2 QDs are facilely synthesized through a one-pot hydrothermal method with fluorescence quantum yield as high as 23.4%, and the strongly fluorescent DNA-CuInS2 QDs have been utilized as a novel fluorescent biosensor for label-free and ultrasensitive detection of anthrax lethal factor DNA. L-Cysteine (L-Cys) and a specific-sequence DNA are used as co-ligands to stabilize the CuInS2 QDs. The specific-sequence DNA consists of two domains: phosphorothiolates domain (sulfur-containing variants of the usual phosphodiester backbone) controls the nanocrystal passivation and serves as a ligand, and the functional domain (non-phosphorothioates) controls the biorecognition. The as prepared DNA-CuInS2 QDs have high stability, good water-solubility and low toxicity. Under the optimized conditions, a linear correlation was established between the fluorescence intensity ratio I/I0 (I0 is the original fluorescence intensity of DNA-CuInS2 QDs, and I is the fluorescence intensity of DNA-CuInS2 QDs/GO with the addition of various concentrations of anthrax lethal factor DNA) and the concentration of anthrax lethal factor DNA in the range of 0.029-0.733 nmol L-1 with a detection limit of 0.013 nmol L-1. The proposed method has been successfully applied to the determination of anthrax lethal factor DNA sequence in human serum samples with satisfactory results. Because of low toxicity and fine biocompatibility, DNA-CuInS2 QDs also hold potential applications in bioimaging. PMID- 27720126 TI - Colorimetric assay for on-the-spot alcoholic strength sensing in spirit samples based on dual-responsive lanthanide coordination polymer particles with ratiometric fluorescence. AB - This study demonstrates a new strategy for colorimetric detection of alcoholic strength (AS) in spirit samples based on dual-responsive lanthanide infinite coordination polymer (Ln-ICP) particles with ratiometric fluorescence. The ICP used in this study are composed of two components: one is the supramolecular Ln ICP network formed by the coordination between the ligand 2,2'-thiodiacetic acid (TDA) and central metal ion Eu3+; and the other is a fluorescent dye, i.e., coumarin 343 (C343), both as the cofactor ligand and as the sensitizer, doped into the Ln-ICP network through self-adaptive chemistry. Upon being excited at 300 nm, the red fluorescence of Ln-ICP network itself at 617 nm is highly enhanced due to the concomitant energy transfer from C343 to Eu3+, while the fluorescence of C343 at 495 nm is supressed. In pure ethanol solvent, the as formed C343@Eu-TDA is well dispersed and quite stable. However, the addition of water into ethanolic dispersion of C343@Eu-TDA destructs Eu-TDA network structure, resulting in the release of C343 from ICP network into the solvent. Consequently, the fluorescence of Eu-TDA turns off and the fluorescence of C343 turns on, leading to the fluorescent color change of the dispersion from red to blue, which constitutes a new mechanism for colorimetric sensing of AS in commercial spirit samples. With the method developed here, we could clearly distinguish the AS of different spirit samples within a wide linear range from 10% vol to 100% vol directly by "naked eye" with the help of UV-lamp (365 nm). This study not only offers a new method for on-the-spot visible detection of AS, but also provides a strategy for dual-responsive sensing mode by rational designing the optical properties of the Ln-ICP network and the guest, respectively. PMID- 27720127 TI - Measuring heterogeneity of reinjury risk assessments at the time of clearance to return to play: A feasibility study. AB - OBJECTIVES: Different individuals may make different return to play (RTP) decisions due to different risk assessments or risk tolerances. Our objectives were to determine the feasibility of eliciting reinjury risk assessments with Bayesian methods, and risk tolerance with questionnaires, from clinicians and athletes in a real-world RTP setting. DESIGN: Feasibility study with a descriptive prospective case-series. METHODS: We recruited the athlete, sport physician and physiotherapist caring for an athlete ("triplet") within on-going groin and hamstring injury studies. We applied Bayesian methods to elicit estimates for reinjury risk over the next 2 months, based on the available clinical knowledge, and projected activity level. We used a standardized questionnaire to elicit factors affecting risk tolerance. RESULTS: Although our methods appeared feasible in general, there were important challenges that included language, time availability of practicing clinicians, and general work flow issues related to embedding our study within an on-going larger study. We did obtain valuable data from more than one person on 10 of the 15 eligible athletes recruited. Despite the limited number of cases, there were clinically meaningful differences in risk estimates in some cases. In one triplet, participants estimated the reinjury risk between 1-10%, 20-50% and 30-40% for the same athlete. The most common factors modifying risk tolerance were "timing and season", "pressure from athlete", and "external pressure". CONCLUSIONS: Bayesian methods for risk elicitation in clinical sport medicine are feasible, and large differences in both risk estimation and risk tolerance sometimes occur. PMID- 27720128 TI - Deviation from goal pace, body temperature and body mass loss as predictors of road race performance. AB - OBJECTIVES: The purpose of this study was to examine the relationship between pacing, gastrointestinal temperature (TGI), and percent body mass loss (%BML) on relative race performance during a warm weather 11.3km road race. DESIGN: Observational study of a sample of active runners competing in the 2014 Falmouth Road Race. METHODS: Participants ingested a TGI pill and donned a GPS enabled watch with heart rate monitoring capabilities prior to the start of the race. Percent off predicted pace (%OFF) was calculated for seven segments of the race. Separate linear regression analyses were used to assess the relationship between pace, TGI, and %BML on relative race performance. One-way ANOVA was used to analyse post race TGI (>=40 degrees C vs <40 degrees C) on pace and %OFF. RESULTS: Larger %BML was associated with faster finish times (R2=0.19, p=0.018), faster average pace (R2=0.29, p=0.012), and a greater %OFF (R2=0.15, p=0.033). %OFF during the first mile (1.61km) significantly predicted overall finish time (R2=0.64, p<0.001) while %OFF during the second mile (3.22km) (R2 change=0.18, p<0.001) further added to the model (R2=0.82, p<0.001). Body temperature (pre race TGI and post race TGI) was not predictive of overall finish time (p>0.05). There was a trend in a slower pace (p=0.055) and greater %OFF (p=0.056) in runners finishing the race with a TGI>40 degrees C. CONCLUSIONS: Overall, finish time was influenced by greater variations in pace during the first two miles of the race. In addition, runners who minimized fluid losses and had lower TGI were associated with meeting self-predicted goals.

AB - INTRODUCTION: This paper presents race-specific breast cancer mortality rates and the corresponding rate ratios for the 50 largest U.S. cities for each of the 5 year intervals between 2005 and 2014. METHODS: The 50 largest cities in the U.S. were the units of analysis. Numerator data were abstracted from national death files where the cause was malignant neoplasm of the breast (ICD-10=C50) for women. Population-based denominators were obtained from the U.S. Census Bureau for 2010-2014. To measure the racial disparity, we calculated Black:White rate ratios (RRs) and confidence intervals for each 5-year period. To determine whether changes over time in the disparity were statistically significant, we calculated a 2-sided z score for the change in the relative percent difference between the Black and White rates for 2005-2009 and 2010-2014. RESULTS: At the most recent time point (2010-2014), the RR was significantly greater than 1.00 in the US and 24 cities. The change in the Black:White disparity was statistically significant in five cities and the US. The percent difference increased significantly in Atlanta, GA (from 4.1 to 117.4, p<0.001); San Antonio, TX (from 24.4 to 79.3, p=0.034); and the US (from 39.7 to 43.1, p=0.007). The percent difference decreased significantly in Memphis, TN (from 111.0 to 68.9, p=0.043); Philadelphia, PA (from 43.1 to 23.5, p=0.049); and Boston, MA (from 48.9 to 0.7, p=0.022). CONCLUSION: This analysis provides updated city-level breast cancer mortality data for Black and White women through 2014, and reveals that in the US and 24 of the 43 largest US cities, Black women continue to die from breast cancer at a higher rate than their White counterparts. Importantly, however, a few cities, Memphis, Boston and Philadelphia, showed a decrease in the Black:White breast cancer mortality disparity between 2005-2009 and 2010-2014.

AB - PURPOSE: Concurrent chemoradiotherapy (CRT) is the standard of care for many sites of locally advanced head and neck squamous cell carcinomas (LAHNC). However, on meta-analysis, the addition of chemotherapy did not improve survival for patients >70years. We hypothesized that elderly patients treated with CRT would have increased toxicity without similar improvements in survival. METHODS: A single-institution, IRB-approved retrospective study took place from 2005 to 2012 including 369 patients treated with CRT for LAHNC. Multivariate models for death at 3months and death over time were developed using logistic regression and Cox modeling, respectively. RESULTS: Patients >=70years were treated less often with concurrent cisplatin dosed every 3weeks (25.5% vs. 71.4%, respectively) and more often with weekly carboplatin (31.9% vs. 3.4%) than patients <70years (n=322; p<0.001). Patients >=70years experienced increased toxicity during treatment with more frequently hospitalizations (36.2% vs. 21.1%; p=0.02) and a lower rate of PEG removal at last follow-up or death (77.1% vs. 92.9%; p=0.004). A higher proportion of patients >=70years died within 3months (12.8% vs. 2.8%; p=0.001) following CRT. Patients >=70 had an increased risk of death at 3months following CRT (odds ratio 5.19, 95% CI 1.64-16.41; p=0.005) and worse survival over time (hazard ratio 2.30, 95% CI 1.34-3.93; p=0.002). CONCLUSIONS: Patients >=70years were more often treated with less toxic chemotherapy, yet experienced higher rates of hospitalization during treatment and increased rates of acute mortality following CRT. The efficacy of chemoradiotherapy for elderly patients should be evaluated in a prospective setting.

AB - Disseminated histiocytic sarcoma (HS) was diagnosed on post-mortem examination of a 1.5-year-old African hedgehog (Atelerix albiventris) that was presented in poor physical condition and with diarrhoea. Leucocytosis and a hypoechoic abdominal mass were noted on haematological and ultrasonographical examinations. Gross pathological, histopathological, immunohistochemical and ultrastructural evaluation of the mass supported a diagnosis of disseminated HS. To our knowledge, this report represents the first documentation of disseminated HS in this species. PMID- 27720132 TI - Sex specific influence on the relationship between maternal exposures to persistent chemicals and birth outcomes. AB - Prenatal exposure to persistent pollutants has been associated with adverse birth outcomes, although few studies have investigated the influence of the sex of the infant. Sex specific differences have been associated with neurobehavioural impacts from environmental exposures with limited and contrary findings in relation to persistent pollutants. This study investigated the relationships between maternal exposure to a range of metals, polychlorinated biphenyls and pesticides measured in biological samples and birth outcomes with a specific focus on the sex of the infant. Outcome measures used included birth weight, birth length and head circumference, proportion of optimal birth weight (POBW), proportion of optimal birth length, proportion of optimal head circumference (POHC) and ponderal index. In general maternal urinary and blood metals, plasma polychlorinated biphenyl and pesticide concentrations were low. In adjusted regression models, a ln-unit increase in plasma beta-hexachlorocyclohexane concentrations was associated with decreased birth weight (-76g, 95% CI -149, 33), ponderal index (-0.048, 95% CI 0.102, 0.007) and proportion of optimal birth weight (-1.5%, 95% CI -3.6, 0.5) in the whole study population, with stronger associations observed for male infants. Maternal p,p' dichlorodiphenyldichloroethylene concentrations were associated with reduced ponderal index in male infants (beta=-0.171, 95% CI -0.269, -0.074). A ln-unit increase in plasma hexachlorobenzene concentrations was associated with a 5% increase in POBW in male infants (95% CI 0.67, 9.5). Increased urinary barium was associated with increased birth length and POBL and decreased ponderal index in boys. Conversely, urinary concentrations of caesium and rubidium were found to be associated with decreased foetal growth in female infants. This study supports the growing body of evidence regarding the reductions in foetal growth associated with beta-hexachlorocyclohexane and p,p'-Dichlorodiphenyldichloroethylene as well as reporting new relationships between metals exposures and birth outcomes. The finding that maternal exposure to barium, strontium, rubidium and caesium was associated with birth outcomes requires confirmation in larger studies. Similarly the apparent differences in susceptibility based on sex of the infant requires further investigation. PMID- 27720133 TI - Assessing the impact of sanitation on indicators of fecal exposure along principal transmission pathways: A systematic review. AB - OBJECTIVE: Fecal-oral transmission of enteric and other pathogens due to poor sanitation is a major cause of morbidity and mortality, especially in low- or middle-income settings. Few studies have investigated the impact of sanitation on indicators of transmission, a prerequisite to achieving health gains. This review attempts to summarize the literature to date. METHODS: We searched leading databases to identify studies that address the effect of sanitation on various transmission pathways including fecal pathogens or indicator bacteria in drinking water, hand contamination, sentinel toys, food, household and latrine surfaces and soil, as well as flies and observations of human feces. This also included studies that assessed the impact of fecal contamination of water supplies based on distance from sanitation facilities. We identified 29 studies that met the review's eligibility criteria. RESULTS AND CONCLUSION: Overall, the studies found little to no effect from sanitation interventions on these transmission pathways. There was no evidence of effects on water quality (source or household), hand or sentinel toy contamination, food contamination, or contamination of surfaces or soil. There is some evidence that sanitation was associated with reductions in flies and a small effect on observations of feces (Risk Difference -0.03, 95%CI 0.06 to 0.01). Studies show an inverse relationship between the distance of a water supply from a latrine and level of fecal contamination of such water supply. Future evaluations of sanitation interventions should include assessments of effects along transmission pathways in order to better understand the circumstances under which interventions may be effective at preventing disease. PMID- 27720134 TI - L-plastin regulates the stability of the immune synapse of naive and effector T cells. AB - T-cells need to be tightly regulated during their activation and effector phase to assure an appropriate defence against cancer or pathogens and - vice versa - to avoid autoimmune reactions. Regulatory signals are provided via the immune synapse between T-cells and antigen-presenting cells (APCs) or target cells. The stability and kinetics of immune synapse formation is critical for proper T-cell functions. It requires dynamic rearrangements of the actin cytoskeleton necessary for organized spatio-temporal redistribution of receptors and adhesion molecules. We identified glucocorticoid-sensitive phosphorylation of serine 5 on the actin bundling protein L-plastin as one important signalling event for this regulation. Using imaging flow cytometry as well as confocal and super-resolution microscopy we showed that L-plastin relocalizes to the immune synapse upon antigen encounter, where it associates with the beta2-subunit of LFA-1 (CD11a/CD18). Interfering with L-plastin expression or activation leads to a defective LFA-1 recruitment and unstable T-cell/APC contacts. Consequently, the lack of L-plastin diminishes T-cell activation, proliferation and proximal effector responses such as cytokine production. On the other hand, a pro-oxidative milieu leads to prolonged activation of L-plastin resulting in a stronger enrichment of LFA-1 in the cytolytic immune synapse. Concomitant stabilization of conjugates formed by cytotoxic T-cells (CTLs) and their target cells impairs the ability of CTLs to kill more than one target cells (serial killing), which de facto leads to a downregulation of T-cell cytotoxicity. Together, we demonstrate that activation and spacial distribution of L-plastin regulates the maturation and stability of activating and cytolytic immune synapses important for T-cell activation and effector functions. PMID- 27720135 TI - [Toward a customized preservation for each kidney graft?] AB - The increased number of patients in waiting list for renal transplantation requires the establishment of recommendations regarding graft preservation techniques. The preservation method impacts graft function and survival particularly in case of extended criteria donors. Based on our experience, the aim of this review is to establish a decisional diagram to draw graft management to 5years in relation to donor type and graft quality. Novel biomarkers are necessary to evaluate graft quality. Nuclear magnetic resonance or transcriptomic analyses are promising. Thus, good quality organs will be preserved in static condition associated to hypothermia; while grafts from extended criteria donors need to be assessed early during dynamic perfusion through an evaluation of perfusion solution to discriminate: good organs, with acceptable risks without perfusion conditions modifications; tolerable risk grafts for which it will be recommended to use a supplementation of perfusion solution with oxygen or pharmacologic additives such as mitochondrion protectors or oxygen carriers; and elevated risks graft which will not be used. This diagram based on experimental data needs to be assessed in clinical trials but highlights the crucial role of kidney graft quality assessment for its management and placed dynamic perfusion preservation as the protocol of choice for extended criteria donors. PMID- 27720136 TI - IMA901, a multipeptide cancer vaccine, plus sunitinib versus sunitinib alone, as first-line therapy for advanced or metastatic renal cell carcinoma (IMPRINT): a multicentre, open-label, randomised, controlled, phase 3 trial. AB - BACKGROUND: In a phase 2 study in patients with metastatic renal cell carcinoma, overall survival was associated with T-cell responses against IMA901, a vaccine consisting of ten tumour-associated peptides. In this phase 3 trial, we aimed to determine the clinical effect of adding IMA901 to sunitinib, the standard first line treatment in metastatic renal cell carcinoma with postulated favourable immunomodulatory effects. METHODS: The IMPRINT study is an open-label, randomised, controlled, phase 3 trial done at 124 clinical sites in 11 countries. HLA-A*02-positive patients (aged >=18 years) with treatment-naive, histologically confirmed metastatic or locally advanced (or both) clear-cell renal cell carcinoma were randomly assigned (3:2) to receive sunitinib plus up to ten intradermal vaccinations of IMA901 (4.13 mg) and granulocyte macrophage colony stimulating factor (75 MUg), with one dose of cyclophosphamide (300 mg/m2) 3 days before the first vaccination, or to receive sunitinib alone. Sunitinib (50 mg) was given orally once daily, with each cycle defined as 4 weeks on treatment followed by 2 weeks off treatment, until progression of disease as determined by the investigator, death, or withdrawal of consent. Block randomisation (block size five) was done centrally using an interactive web response system, stratified by prognostic risk, geographical region, and previous nephrectomy. Patients and investigators were not masked to treatment allocation. The primary endpoint was overall survival from randomisation until death of any cause as determined by the investigator, analysed by intention to treat. This study is registered with ClinicalTrials.gov, number NCT01265901. FINDINGS: Between Dec 22, 2010, and Dec 15, 2012, we screened 1171 patients, of whom 339 were randomly assigned to receive sunitinib plus IMA901 (n=204) or sunitinib monotherapy (n=135). Patients had a median follow-up of 33.27 months (IQR 29.92-35.64). Median overall survival did not differ significantly between the groups (33.17 months [95% CI 27.81-41.36] in the sunitinib plus IMA901 group vs not reached [33.67-not reached] in the sunitinib monotherapy group; hazard ratio 1.34 [0.96 1.86]; p=0.087). 116 (57%) of 202 patients in the sunitinib plus IMA901 group and 62 (47%) of 132 in the sunitinib group had grade 3 or worse adverse events, the most common of which were hypertension, neutropenia, and anaemia in both groups, and mild-to-moderate transient injection-site reactions (eg, erythema, pruritus) were the most frequent IMA901-related side-effect in the sunitinib plus IMA901 group. Serious adverse events leading to death occurred in four (2%) patients (one respiratory failure and circulatory collapse [possibly related to sunitinib], one oesophageal varices haemorrhage [possibly related to sunitinib], one cardiac arrest [possibly related to sunitinib], and one myocardial infarction) and eight (6%) patients in the sunitinib group (one case each of renal failure, oesophageal varices haemorrhage, circulatory collapse, wound infection, ileus, cerebrovascular accident [possibly treatment related], and sepsis). INTERPRETATION: IMA901 did not improve overall survival when added to sunitinib as first-line treatment in patients with metastatic renal cell carcinoma. The magnitude of immune responses needs to be improved before further development of IMA901 in this disease is indicated. FUNDING: Immatics Biotechnologies. PMID- 27720137 TI - Vaccine therapy in renal cell carcinoma: attempting to leap over a rising bar. PMID- 27720138 TI - Physics of metabolic organization. AB - We review the most comprehensive metabolic theory of life existing to date. A special focus is given to the thermodynamic roots of this theory and to implications that the laws of physics-such as the conservation of mass and energy have on all life. Both the theoretical foundations and biological applications are covered. Hitherto, the foundations were more accessible to physicists or mathematicians, and the applications to biologists, causing a dichotomy in what always should have been a single body of work. To bridge the gap between the two aspects of the same theory, we (i) adhere to the theoretical formalism, (ii) try to minimize the amount of information that a reader needs to process, but also (iii) invoke examples from biology to motivate the introduction of new concepts and to justify the assumptions made, and (iv) show how the careful formalism of the general theory enables modular, self-consistent extensions that capture important features of the species and the problem in question. Perhaps the most difficult among the introduced concepts, the utilization (or mobilization) energy flow, is given particular attention in the form of an original and considerably simplified derivation. Specific examples illustrate a range of possible applications-from energy budgets of individual organisms, to population dynamics, to ecotoxicology. PMID- 27720139 TI - Patient portals and health apps: Pitfalls, promises, and what one might learn from the other. AB - Widespread use of health information technology (IT) could potentially increase patients' access to their health information and facilitate future goals of advancing patient-centered care. Despite having increased access to their health data, patients do not always understand this information or its implications, and digital health data can be difficult to navigate when displayed in a small format, complex interface. In this paper, we discuss two forms of patient-facing health IT tools-patient portals and applications (apps)-and highlight how, despite several limitations of each, combining high-yield features of mobile health (mHealth) apps with portals could increase patient engagement and self management and be more effective than either of them alone. Patient portal adoption is variable, and due to design and interface limitations and health literacy issues, many people find the portal difficult to use. Conversely, apps have experienced rapid adoption and traditionally have more consumer-friendly features with easy log-in access, real-time tracking, and simplified data display. These features make the applications more intuitive and easy-to-use than patient portals. While apps have their own limitations and might serve different purposes, patient portals could adopt some high-yield features and functions of apps that lead to engagement success with patients. We thus suggest that to improve user experience with future portals, developers could look towards mHealth apps in design, function, and user interface. Adding new features to portals may improve their use and empower patients to track their overall health and disease states. Nevertheless, both these health IT tools should be subjected to rigorous evaluation to ensure they meet their potential in improving patient outcomes. PMID- 27720141 TI - Harnessing Integrated Vector Management for Enhanced Disease Prevention. AB - The increasing global threat of emerging and re-emerging vector-borne diseases (VBDs) poses a serious health problem. The World Health Organization (WHO) recommends integrated vector management (IVM) strategy for combating VBD transmission. An IVM approach requires entomological knowledge, technical and infrastructure capacity, and systems facilitating stakeholder collaboration. In sub-Saharan Africa, successful operational IVM experience comes from relatively few countries. This article provides an update on the extent to which IVM is official national policy, the degree of IVM implementation, the level of compliance with WHO guidelines, and concordance in the understanding of IVM, and it assesses the operational impact of IVM. The future outlook encompasses rational and sustainable use of effective vector control tools and inherent improved return for investment for disease vector control. PMID- 27720140 TI - Disease Centered Around Calcified Taenia solium Granuloma. AB - Taenia solium (the pork tapeworm) is present in most developing countries, where it is a frequent cause of seizures and other neurological disease. Parasitic larvae invade the human brain, establish, and eventually resolve, leaving a calcified scar. While these lesions are common in endemic regions, and most of these are clinically silent, a proportion of individuals with calcified cysticerci develop seizures from these lesions, and 30-65% of these cases are associated with perilesional edema (PE), likely due to host inflammation. This manuscript summarizes the importance, characteristics, natural history, and potential prevention and treatments of symptomatic calcified neurocysticercosis (NCC). PMID- 27720143 TI - Sodium and potassium intake in South Africa: an evaluation of 24-hour urine collections in a white, black, and Indian population. AB - Limited number of studies on salt intake has been conducted in the South Africa. The present study established the sodium and potassium excretion (24-hour urine collection) of three different South African populations. In total, 692 successful 24-hour urine collections were analyzed for sodium, potassium, and iodine levels. The median sodium and potassium excretion was 122.9 and 33.5 mmol/d, respectively, and the median salt intake was 7.2 g/d. The majority (92.8%) of the population did not meet the recommended potassium intake/d, and 65.6% consumed more than 6 g of salt/d. Potassium excretion showed a linear relationship with salt intake (P-trend <= .001). The median sodium-to-potassium ratio was 3.5. These findings support the South African government's sodium reduction legislation, as well as global initiatives. More consideration should be given to promoting the intake of potassium-rich foods, as this may have a greater public health impact than focusing only on dietary sodium reduction. PMID- 27720142 TI - Patient characteristics associated with greater blood pressure control in a randomized trial of home blood pressure telemonitoring and pharmacist management. AB - This paper reports subgroup analysis of a successful cluster-randomized trial to identify attributes of hypertensive patients who benefited more or less from an intervention combining blood pressure (BP) telemonitoring and pharmacist management. The end point was BP < 140/90 mm Hg at 6-month follow-up. Fourteen baseline patient characteristics were selected a priori as subgroup variables. Among the 351 trial participants, 44% were female, 84% non-Hispanic white, mean age was 60.9 years, and mean BP was 149/86 mm Hg. The overall adjusted odds ratio for BP control in the intervention versus usual care group was 3.64 (P < .001). The effect of the intervention was significantly larger in patients who were younger (interaction P = .02), did not have diabetes (P = .005), had high baseline diastolic BP (P = .02), added salt less than daily in food preparation (P = .007), and took 0-2 (rather than 3-6) antihypertensive medication classes at baseline (P = .02). These findings may help prioritize patients for whom the intervention is most effective. PMID- 27720144 TI - A new cichlid fish in the Sahara: The Ounianga Serir lakes (Chad), a biodiversity hotspot in the desert. AB - In the rare perennial bodies of water of the Sahara desert, only a few fish species have survived to increasing aridification since the end of the last humid period at the Holocene, approximately 5000 years BP. Here, I report the occurrence of an undescribed haplochomine cichlid fish in Lake Boukou, one of the seven Ounianga Serir lakes (Chad). These lakes are located in one of the most arid areas of the Sahara desert, but they persist by virtue of subsurface inflow of fresh groundwater from a large fossil aquifer. Astatotilapia tchadensis sp. nov. is characterized by a black bar between eye and corner of mouth, rounded orange spots on anal fin, scales ctenoid, lower limb of first gill arch with 7-8 gill rackers, dorsal fin with 13-14 spines and 9-11 soft rays, anal fin with 3 spines and 8-9 soft rays, 29 or 30 lateral line scales, and lower pharyngeal dentition with enlarged molariform teeth. The new species is easily distinguished from A. desfontainii and A. flaviijosephii, the northernmost haplochromine species currently isolated from its other group members, and appears close to an unnamed species of Lake Chad basin. Ounianga Serir lakes and especially Lake Boukou present a remarkable diversity of fish, the highest known in the Sahara desert with a total of at least six fish species belonging to six genera and three families. They also constitute an exceptional natural landscape inscribed on the UNESCO world heritage list in 2012 and a biodiversity hotspot for desert vertebrate species. PMID- 27720145 TI - Archaeobotanical reconstructions of vegetation and report of mummified apple seeds found in the cellar of a first-century Roman villa on Elba Island. AB - In the late Roman Republic period (2nd-1st century BC), in the area of San Giovanni on Elba Island, previously subject to intense extraction of iron ore, a rustic villa was established by Marco Valerio Messalla, a supreme Roman magistrate. The foundations of the walls were discovered and excavated by an archaeological mission. Palaeobotanical analysis of a set of stratigraphic layers was performed. Palynological slides showed remains of palynomorphic and non pollen objects, while data combined with anthracological investigations confirmed the hypothesis that in the 1st century AD the villa was destroyed by a fire that created a compact crust under which were discovered four broken Roman amphorae containing about five hundred apple seeds. Comparisons of archaeological and fresh seeds from reference collections showed discontinuous morphology except for one group of archaeological samples. DNA was isolated from seeds that had well preserved embryos in all groups. DNA extracts from archaeological, wild and modern domestic seeds (controls) were amplified by PCR and tested with SSR molecular markers, followed by genome analysis. PMID- 27720146 TI - Short communication: Rumination and feeding behaviors differ between healthy and sick dairy cows during the transition period. AB - The objectives of this study were: (1) to describe the rumination and feeding behavior of freestall-housed Holstein dairy cows in the weeks around parturition, and (2) to determine the relationship between postpartum disease and precalving rumination and feeding behavior. Eighty cows were enrolled at approximately 2wk (18+/-7d, mean +/- standard deviation) before calving. Using automatic monitoring systems, rumination and feeding behavior were recorded continuously from 10d before until 3wk after calving. Postpartum health checks were performed each day, and metritis assessment was conducted 2 times/wk. Blood beta-hydroxybutyrate was measured 3 times/week, and cows with >=1.2mmol/L during the first 14d postpartum were diagnosed as having subclinical ketosis. The final data set included 64 cows in 5 groups: healthy (n=20), metritis (n=18), subclinical ketosis (SCK; n=9), metritis+SCK (n=9), and >1 health problem and not included before (MULT, n=8). We compared rumination and feeding data between healthy cows and the 4 categories of ill animals in each of 4 periods relative to calving: precalving (d -7 to -2), period 1 (d 3 to 8 postpartum), period 2 (d 9 to 14 postpartum), and period 3 (d 15 to 20 postpartum). Cows with SCK spent less time ruminating during the precalving period. Compared with healthy cows, those with SCK and metritis+SCK had lower dry matter intake during the precalving period and continued to eat less until d 14 and d 20 postpartum, respectively. Cows with metritis and MULT cows had lower dry matter intake during the first 2wk postpartum. Precalving feeding time was lower for SCK, metritis+SCK, and MULT cows compared with healthy cows. The difference in feeding time between healthy and metritis+SCK cows had disappeared by period 2 and between all health categories except MULT by period 3. MULT cows visited the feed bins less often and were less often replaced at the feed bin throughout all 4 periods of the study. Automatic monitoring of intake and rumination showed promise for the detection of health problems after calving. We observed differences in precalving rumination and feeding behavior. Further research is necessary to better understand the onset of behavioral changes and the relationship between rumination and disease. PMID- 27720147 TI - Adipose tissue remodeling in late-lactation dairy cows during feed-restriction induced negative energy balance. AB - Excessive rates of demand lipolysis in the adipose tissue (AT) during periods of negative energy balance (NEB) are associated with increased susceptibility to disease and limited lactation performance. Lipolysis induces a remodeling process within AT that is characterized by an inflammatory response, cellular proliferation, and changes in the extracellular matrix (ECMT). The adipose tissue macrophage (ATM) is a key component of the inflammatory response. Infiltration of ATM-forming cellular aggregates was demonstrated in transition cows, suggesting that ATM trafficking and phenotype changes may be associated with disease. However, it is currently unknown if ATM infiltration occurs in dairy cows only during NEB states related to the transition period or also during NEB-induced lipolysis at other stages of lactation. The objective of this study was to evaluate changes in ATM trafficking and inflammatory phenotypes, and the expression of genetic markers of AT remodeling in healthy late-lactation cows during feed restriction-induced NEB. After a 14-d (d -14 to d -1) preliminary period, Holstein cows were randomly assigned to 1 of 2 feeding protocols, ad libitum (AL) or feed restriction (FR), for 4 d (d 1-4). Caloric intake was reduced in FR to achieve a targeted energy balance of -15 Mcal/d of net energy for lactation. Omental and subcutaneous AT samples were collected laparoscopically to harvest stromal vascular fraction (SVF) cells on d -3 and 4. The FR induced a NEB of -14.1+/-0.62 Mcal/d of net energy for lactation, whereas AL cows remained in positive energy balance (3.2+/-0.66 Mcal/d of NEL). The FR triggered a lipolytic response reflected in increased plasma nonesterified fatty acids (0.65+/-0.05 mEq/L on d 4), enhanced phosphorylation of hormone sensitive lipase, and reduced adipocyte diameter. Flow cytometry and immunohistochemistry analysis revealed that on d 4, FR cows had increased numbers of CD172a+, an ATM (M1 and M2) surface marker, cells in SVF that were localized in aggregates. However, FR did not alter the number of SVF cells expressing M1 markers (CD14 and CD11c) or M2 markers (CD11b and CD163). This finding contrasts with the predominately M1 phenotype observed previously in ATM from clinically diseased cows. No changes were observed in the expression of ECMT-related or cell proliferation markers. In summary, an acute 4-d lipolytic stimulus in late lactation dairy cows led to ATM infiltration with minimal changes in inflammatory phenotype and no changes in ECMT. These results underscore that physiological changes related to parturition, the onset of lactation, extended periods of lipolysis, or a combination of these can induce intense AT remodeling with enhanced ATM inflammatory phenotype expression that may impair the metabolic function of AT in transition dairy cattle. PMID- 27720148 TI - Changes in the intestinal bacterial community, short-chain fatty acid profile, and intestinal development of preweaned Holstein calves. 2. Effects of gastrointestinal site and age. AB - The objective of this work was to assess the effects of age and gastrointestinal location (rumen vs. colon) on bacterial community diversity and composition, as well as short-chain fatty acid profiles of preruminant male Holstein calves on an intensive milk replacer feeding program. Thirty-two calves were fed at 2% of their body weight (dry matter basis) from d 10 until harvest. Sixteen calves were euthanized at 2wk and another 16 at 4wk of age to collect digesta samples from the rumen and colon. The rumen and colon bacterial communities of preruminant calves showed a similar degree of diversity (i.e., Shannon index) whereas composition differed considerably. The colonic bacterial population was characterized by dominance of lactic acid bacteria such as Lactobacillus, Streptococcus, Enterococcus, and Bifidobacterium. In addition, colonic short chain fatty acid and lactic acid concentrations were between 50 and 850% higher than in the rumen, indicating greater fermentative activity in the colon. On the other hand, in the rumen, no genus over-dominated and more variation was present among calves. Because of an active reticular groove and low starter grain intake during the first 1 to 3wk of life, ruminal fermentation may not contribute to significant metabolizable energy supply until after 4wk of life in intensively fed calves. Until then, calf hindgut fermentation, characterized by high abundance of lactic acid bacteria along with increased lactate and butyrate concentrations, could be beneficial for intestinal health and survival of the calf during the first weeks of life. PMID- 27720149 TI - Determination of ultra-low milk fat content using dual-wavelength ultraviolet spectroscopy. AB - A precise determination of milk fat content in dairy products is of great practical importance. Several studies have reported methods to determine the milk fat content in commercial dairy products. However, very few of them validated or tested cases where the fat milk fat content was ultra-low. Here we present an approach to determine ultra-low milk fat content. This method involves extracting milk fat using n-heptane and determining its content using dual-wavelength UV spectroscopy. The results showed that milk fat at ultra-low concentrations (i.e., as low as 0.148 g/L) could be extracted completely and quantified accurately using the proposed approach. This method is reproducible and sufficiently precise. We expect that this method can be adapted by industries to determine ultra-low concentration of fat in milk and other dairy products with confidence. PMID- 27720150 TI - Changes in the intestinal bacterial community, short-chain fatty acid profile, and intestinal development of preweaned Holstein calves. 1. Effects of prebiotic supplementation depend on site and age. AB - Digestive disorders are common during the first few weeks of life of newborn calves. Prebiotics are nondigestible but fermentable oligosaccharides that modulate growth and activity of beneficial microbial populations, which can result in enhanced gut health and function. Galactooligosaccharides (GOS) have demonstrated such prebiotic potential. In this study, the effect of GOS supplementation on intestinal bacterial community composition and fermentation profiles; intestinal health, development, and function; and growth was evaluated in dairy calves fed for high rates of growth. Eighty male Holstein calves were assigned either to a control treatment consisting of commercial milk replacer or to a GOS-rich (i.e., 3.4% of dry matter) milk replacer treatment. After 2 and 4wk, 8 calves per treatment were slaughtered at each age. Samples of intestinal digesta and tissue were collected for assessment of bacterial communities, short chain fatty acid concentrations, in vitro measurement of nutrient transport and permeability, histomorphology, and gastrointestinal organ size. The remaining 48 calves continued to wk 8 to measure body growth, nutrient intake, and fecal and respiratory scores. Calves fed GOS displayed greater Lactobacillus and Bifidobacterium relative abundance and more developed intestinal epithelial structures, but also had greater fecal scores presumably related to greater colonic water secretion. Control calves showed slightly better growth and milk dry matter intake. Size of intestinal organs, intestinal nutrient transport, and epithelium paracellular resistance were not affected by treatment. Excessive GOS supplementation had both prebiotic and laxative effects, which led to slightly lower growth performance while promoting commensal bacteria population and greater intestinal epithelium growth.

AB - The objective was to test the hypothesis that more frequent but less accurately analyzed milk components may give a more representative measure of a cow's total lactation production. Daily records for milk production and fat and protein concentration collected by the AfiLab recording system (Afimilk, Kibbutz Afikim, Israel) from January 2014 to January 2016 from 47 large kibbutz (communal) herds distributed throughout Israel with a total of 37,486 Israeli Holstein cows were compared with the same statistics derived from monthly test day records derived by Bentley and Foss milk analyzers at the central laboratory of the Israel Cattle Breeders Association. The lactation means for all traits were quite similar for the 2 methods in both parities, except for fat production, which was lower for the daily records. This finding corresponded to fat lactation curves, which showed that daily results were lower with low days in milk (DIM) but almost equal to the monthly results after 125 DIM. Relative to monthly records, daily records overestimated protein percentage before 150 DIM and underestimated protein percentage in the second half of the lactation. The standard deviation for first- and second-parity daily records scored by the monthly and daily system were least similar for fat percentage, but even for this trait the difference was no more than 0.1 percentage points. The standard deviations for complete lactation production were slightly lower for the daily results for all traits but protein production. First-parity heritabilities were higher for lactations computed from daily records for all traits except for protein percentage, but differences were not significant. For daily records, coefficients of determination to predict future milk, fat, and protein lactation production from truncated lactations were greatest and root mean squared errors were least if the mean production from the last 2 weeks before the truncation date was used to estimate future production. Daily first-parity partial lactations for milk, fat, and protein production with <150 DIM predicted future lactation more accurately than corresponding monthly partial lactations. With only 30 DIM, genetic correlations between predicted and actual lactations ranged from 0.73 to 0.79 for milk, fat, and protein production. Real-time daily recording of fat and protein concentration by the daily recording system may be preferable to monthly analysis for herd-management decisions and genetic evaluation. Further study is required to compare the results of individual cows in multiple lactations. PMID- 27720151 TI - Predicting the distribution of whey protein fouling in a plate heat exchanger using the kinetic parameters of the thermal denaturation reaction of beta lactoglobulin and the bulk temperature profiles. AB - Fouling of plate heat exchangers (PHE) is a severe problem in the dairy industry, notably because the relationship between the build-up of protein fouling deposits and the chemical reactions taking place in the fouling solution has not yet been fully elucidated. Experiments were conducted at pilot scale in a corrugated PHE, and fouling deposits were generated using a model beta-lactoglobulin (beta-LG) fouling solution for which the beta-LG thermal denaturation reaction constants had been previously determined experimentally. Then 18 different bulk temperature profiles within the PHE were imposed. Analysis of the fouling runs shows that the dry deposit mass per channel versus the ratio R=kunf/kagg (with kunf and kagg representing, respectively, the unfolding and aggregation rate constants computed from both the identification of the beta-LG thermal denaturation process and knowledge of the imposed bulk temperature profile into the PHE channel) is able to gather reasonably well the experimental fouling mass data into a unique master curve. This type of representation of the results clearly shows that the heat induced reactions (unfolding and aggregation) of the various beta-LG molecular species in the bulk fluid are essential to capture the trend of the fouling mass distribution inside a PHE. This investigation also illustrates unambiguously that the release of the unfolded beta-LG (also called beta-LG molten globule) within the bulk fluid (and the absence of its consumption in the form of aggregates) is a key phenomenon that controls the extent of protein fouling as well as its location inside the PHE. PMID- 27720153 TI - Short communication: Genetic variation in choice consistency for cows accessing automatic milking units. AB - Dairy cows milked in automatic milking systems (AMS) with more than 1 milking box may, as individuals, have a preference for specific milking boxes if allowed free choice. Estimates of quantitative genetic variation in behavioral traits of farmed animals have previously been reported, with estimates of heritability ranging widely. However, for the consistency of choice in dairy cows, almost no published estimates of heritability exist. The hypothesis for this study was that choice consistency is partly under additive genetic control and partly controlled by permanent environmental (animal) effects. The aims of this study were to obtain estimates of genetic and phenotypic parameters for choice consistency in dairy cows milked in AMS herds. Data were obtained from 5 commercial Danish herds (I-V) with 2 AMS milking boxes (A, B). Milking data were only from milkings where both the present and the previous milkings were coded as completed. This filter was used to fulfill a criterion of free-choice situation (713,772 milkings, 1,231 cows). The lactation was divided into 20 segments covering 15d each, from 5 to 305d in milk. Choice consistency scores were obtained as the fraction of milkings without change of box [i.e., 1.0 - u(box change)] for each segment. Data were analyzed for one part of lactation at a time using a linear mixed model for first parity cows alone and for all parities jointly. Choice consistency was found to be only weakly heritable (heritability=0.02 to 0.14) in first as well as in later parities, and having intermediate repeatability (repeatability coefficients=0.27 to 0.56). Heritability was especially low at early and late lactation states. These results indicate that consistency, which is itself an indication of repeated similar choices, is also repeatable as a trait observed over longer time periods. However, the genetic background seems to play a smaller role compared with that of the permanent animal effects, indicating that consistency could also be a learned behavior. We concluded that consistency in choices are quantifiable, but only under weak genetic control. PMID- 27720154 TI - Characterization of Escherichia coli and other Enterobacteriaceae in producer distributor bulk milk. AB - The current study was undertaken to characterize Escherichia coli and other Enterobacteriaceae in raw and pasteurized producer-distributor bulk milk (PDBM). A total of 258 samples were collected from purchase points in 8 provinces in South Africa. The samples were tested for antibiotic residues, phosphatase, total aerobic bacteria, coliforms, and E. coli counts. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was used for identification of isolates. Escherichia coli isolates were characterized for virulence factors, antimicrobial resistance, serotypes, and presumptive E. coli O157:H7. Antibiotic residues and alkaline phosphatase were detected in 2% of both raw and pasteurized PDBM (n=258) and 21% pasteurized PDBM (n=104) samples, respectively. A total of 729 isolates belonging to 21 genera and 59 species were identified. Escherichia coli, Enterobacter cloacae, Klebsiella oxytoca, and Raoultella ornithinolytica were the most abundant species. Spoilage Enterobacteriaceae species exceeded 50% of the total isolates. Escherichia coli was detected and isolated from 36% of the milk samples. Thirty-one E. coli isolates harbored virulence genes stx1/stx2 and 38% (n=121) were presumptive O157:H7. The prevalence of samples with presumptive shigatoxin producing E. coli was 10%. Antimicrobial-resistant E. coli isolates were detected in 70% of the milk samples with 36% of stx1/stx2 positive E. coli showing multi-drug resistance. Information obtained from the study will be used for modeling the public health risk posed by milkborne pathogens in PDBM, which in many cases is consumed by poor and vulnerable members of the population. PMID- 27720155 TI - Physiological predictors of ovulation and pregnancy risk in a fixed-time artificial insemination program. AB - The objective of this study was to determine the relative importance and contribution of several physiological factors as predictors of pregnancy risk in an Ovsynch (GnRH-1 - 7d - PGF2alpha - 56h - GnRH-2 - 16h - artificial insemination) timed artificial insemination program: (1) age of the corpus luteum (CL; original CL, new CL, or both in response to GnRH-1) and resulting progesterone concentrations as they affected luteolysis, ovulation after GnRH-2, and pregnancy risk; (2) progesterone concentration before GnRH-1 and GnRH-2 on subsequent ovulatory response to GnRH-1 and GnRH-2 as well as pregnancy risk; and (3) a combination of these factors in a multivariable logistic regression model to predict pregnancy risk. Original data from 7 published studies were combined including ovulatory responses to both GnRH injections, blood progesterone concentrations before GnRH-1, before PGF2alpha, and at 48h after PGF2alpha, pregnancy per artificial insemination at d 32 and 60 after artificial insemination, and intervening pregnancy loss. Ovulation outcomes were greater at lesser progesterone concentrations after both GnRH injections despite the fact that pregnancy outcomes were greatest when progesterone exceeded 3ng/mL before GnRH-1 and PGF2alpha, suggesting that greater progesterone concentration before GnRH-1 and incidence of ovulation act via different mechanisms to improve subsequent fertility. Ovulation after GnRH-2 and subsequent pregnancy outcome were positively related to lesser concentrations of progesterone at 48h after PGF2alpha; however, for maximal pregnancy outcome, progesterone should be <0.5ng/mL. Cows with a CL that also formed a new CL after GnRH-1 had the greatest pregnancy outcome, whereas cows with only a new CL (i.e., anovulatory cows and those at or near estrus without a CL at GnRH-1) had the poorest pregnancy outcome. Pregnancy loss was not affected by CL status during the timed artificial insemination program. Receiver operator curves produced cut points of progesterone concentration that predicted ovulation and pregnancy risk. Selected cut points of progesterone concentration 48h after PGF2alpha produced true positive risks greater than 90% and false positive risks less than 25%, thus demonstrating the high predictability of ovulation after GnRH-2 and subsequent pregnancy outcome based on progesterone concentration. We conclude that progesterone concentration is highly predictive of ovulation and pregnancy risk in addition to body condition, size of ovulatory follicle, and parity. PMID- 27720156 TI - Identification of factors influencing teat dip efficacy trial results by meta analysis. AB - Two meta-analyses were conducted using data from peer-reviewed natural exposure (NE) and experimental challenge (EC) teat dip efficacy trials to identify factors influencing the new intramammary infection (IMI) rate. A NE data set containing 16 studies and an EC data set containing 21 studies were created. New IMI rate was calculated based on the percentage of new quarter infections per month (PNQI/mo) for each observation, in both data sets, and used as the dependent variable for model derivation. A linear, mixed-effects model with a random study effect, weighted by number of quarters eligible for infection, was derived for each data set. The final NE model included the effects of experimental design (split herd or split udder), mastitis pathogen group (Staphylococcus aureus, Streptococcus agalactiae, environmental streptococci, gram-negative species, Corynebacterium spp., or coagulase-negative staphylococci), postmilking treatment (iodine, chlorhexidine, linear dodecyl benzene sulfonic acid, chlorine compounds, phenol compounds, or undipped negative controls), and the interaction between mastitis pathogen group and postmilking treatment. Overall, Corynebacterium spp. had the highest new IMI rate (0.0139+/-0.0018 PNQI/mo), and environmental streptococci and gram-negative species had the lowest (0.0023+/-0.0022 PNQI/mo). Additionally, trials utilizing a split herd experimental design had a 2-fold higher new IMI rate than trials using a split udder design. The final EC model included the effects of mastitis pathogen (Staph. aureus and Strep. agalactiae), postmilking treatment (iodine, chlorine compounds, "other" active ingredients, or undipped negative controls), geographic region of study (Eastern, Southern, and Pacific Northwest), and the 2-way interactions of region and pathogen group and postmilking treatment and pathogen group. Overall, Staph. aureus and Strep. agalactiae had similar new IMI rates. Quarters dipped postmilking in either iodine (0.0127+/-0.0099 PNQI/mo), chlorine compounds (0.0258+/-0.0095 PNQI/mo), or "other" active ingredient teat dips (0.0263+/-0.0106 PNQI/mo) had lower new IMI rates than undipped quarters (0.0859+/-0.0087 PNQI/mo). These results indicate that experimental design influences the new IMI rate of teat dip efficacy trials and that using an effective postmilking teat dip has a greater effect on controlling the new Staph. aureus and Strep. agalactiae IMI rate than the teat dip's active ingredient. PMID- 27720157 TI - Substantial replacement of lactose with fat in a high-lactose milk replacer diet increases liver fat accumulation but does not affect insulin sensitivity in veal calves. AB - In veal calves, the major portion of digestible energy intake originates from milk replacer (MR), with lactose and fat contributing approximately 45 and 35%, respectively. In veal calves older than 4 mo, prolonged high intakes of MR may lead to problems with glucose homeostasis and insulin sensitivity, ultimately resulting in sustained insulin resistance, hepatic steatosis, and impaired animal performance. The contribution of each of the dietary energy sources (lactose and fat) to deteriorated glucose homeostasis and insulin resistance is currently unknown. Therefore, an experiment was designed to compare the effects of a high lactose and a high-fat MR on glucose homeostasis and insulin sensitivity in veal calves. Sixteen male Holstein-Friesian calves (120+/-2.8kg of BW) were assigned to either a high-lactose (HL) or a high-fat (HF) MR for 13 consecutive weeks. After at least 7 wk of adaptation, whole-body insulin sensitivity and insulin secretion were assessed by euglycemic-hyperinsulinemic and hyperglycemic clamps, respectively. Postprandial blood samples were collected to assess glucose, insulin, and triglyceride responses to feeding, and 24-h urine was collected to quantify urinary glucose excretion. At the end of the trial, liver and muscle biopsies were taken to assess triglyceride contents in these tissues. Long-term exposure of calves to HF or HL MR did not affect whole-body insulin sensitivity (averaging 4.2+/-0.5*10-2 [(mg/kg?min)/(MUU/mL)]) and insulin secretion. Responses to feeding were greater for plasma glucose and tended to be greater for plasma insulin in HL calves than in HF calves. Urinary glucose excretion was substantially higher in HL calves (75+/-13g/d) than in HF calves (21+/-6g/d). Muscle triglyceride content was not affected by treatment and averaged 4.5+/ 0.6g/kg, but liver triglyceride content was higher in HF calves (16.4+/-0.9g/kg) than in HL calves (11.2+/-0.7g/kg), indicating increased hepatic fat accumulation. We conclude that increasing the contribution of fat to the digestible energy intake from the MR from 20 to 50%, at the expense of lactose does not affect whole-body insulin sensitivity and insulin secretion in calves. However, a high-lactose MR increases postprandial glucose and insulin responses, whereas a high-fat MR increases fat accumulation in liver but not muscle. PMID- 27720158 TI - Mortality risk factors for calves entering a multi-location white veal farm in Ontario, Canada. AB - Mortality in preweaned dairy-breed calves, whether they are replacement dairy heifers, veal animals, or dairy beef animals, represents both a welfare issue and a source of economic loss for the industries involved. Studies describing morbidity and mortality in veal calves have illustrated different management practices and requirements in terms of housing and nutrition around the world. Studies examining the rearing of replacement dairy heifers have shown that rates of morbidity and mortality can vary dramatically between farms, perhaps reflecting differences in management strategies. It has been over 2 decades since morbidity and mortality in veal calves in Ontario were described. The objective of this retrospective population cohort study was to describe mortality and determine whether on-arrival information could be used to predict mortality risk. Predictors could be used to both better classify and group calves on arrival and provide feedback to suppliers about the characteristics of the highest- and lowest-risk calves. We collected data from 10,910 calves entering 7 barns of a single white veal farm, all in Ontario, from January 1 to December 31, 2014. Calves were followed until death or marketing (typically 140 to 150 d). We developed logistic regression models to determine the effects of weight on arrival, season of arrival, supplier, sex, barn, and purchase price on the risk of total mortality, early mortality (0-21d after arrival), and late mortality (>21d after arrival). We identified significant associations between season, barn, supplier, weight, and total mortality risk, with lighter-weight calves arriving in winter being at increased risk. Early mortality was significantly associated with weight, season, barn, and supplier, and tended to be associated with standardized price; lighter-weight calves arriving in winter at lower prices were at increased risk. Late mortality was significantly associated with season of arrival, barn, and supplier. On-arrival measures better predicted early mortality compared with late or total mortality. A further exploration of risk factors from the dairy farm of origin for veal calf mortality would serve to improve the productivity and welfare of calves of both sexes born on dairy farms. PMID- 27720159 TI - Evaluation of dietary betaine in lactating Holstein cows subjected to heat stress. AB - Betaine (BET), a natural, organic osmolyte, improves cellular efficiency by acting as a chaperone, refolding denatured proteins. To test if dietary BET reduced the effect of heat stress (HS) in lactating dairy cows, multiparous, lactating Holstein cows (n=24) were blocked by days in milk (101.4+/-8.6 d) and randomly assigned to 1 of 3 daily intakes of dietary BET: the control (CON) group received no BET, mid intake (MID) received 57mg of BET/kg of body weight, and high dose (HI) received 114mg of BET/kg of body weight. Cows were fed twice daily and BET was top-dressed at each feeding. Cows were milked 2 times/d and milk samples were taken daily for analysis. Milk components, yield, feed intake, and water intake records were taken daily. Rectal temperature and respiration rate were taken 3 times/d at 0600, 1400, and 1800h. Cows were housed in environmentally controlled rooms and were allowed acclimation for 7d at thermoneutral (TN) conditions with a mean temperature-humidity index of 56.6. Cows were then exposed to 7d of TN followed by 7d of HS represented by a temperature-humidity index of 71.5 for 14d. This was followed by a recovery period of 3d at TN. Dietary BET increased milk yield during the TN period. No differences were found between BET and CON in total milk production or milk composition during HS. The increase in water intake during HS was not as great for cows fed BET compared with controls. The cows on CON diets had higher p.m. respiration rate than both MID and HI BET during HS, but lower rectal temperature compared with BET. No difference was found in serum glucose during TN, but cows given HI had elevated glucose levels during HS compared with CON. No differences were found in serum insulin levels between CON and BET but an intake by environment interaction was present with insulin increasing in HI-treated lactating dairy cows during HS. The heat shock response [heat shock protein (HSP) 27 and HSP70] was upregulated in bovine mammary epithelial cells in vitro. Blood leukocyte HSP27 was downregulated at the HI dose under TN conditions and HSP70 was upregulated at the HI dose and this effect was increased by HS. No effect was seen with the MID dose with HSP27 or HSP70. The lack of effect of BET at MID may be associated with uptake across the gut. We conclude that BET increased milk production under TN conditions and was associated with reduced feed and water intake and slightly increased body temperatures during HS of cows fed BET. The effect of BET on milk production was lost during HS with HI BET, whereas serum glucose levels increased during HS. PMID- 27720160 TI - Identifying management and disease priorities of Canadian dairy industry stakeholders. AB - The objective of this study was to identify the key management and disease issues affecting the Canadian dairy industry. An online questionnaire (FluidSurveys, http://fluidsurveys.com/) was conducted between March 1 and May 31, 2014. A total of 1,025 responses were received from across Canada of which 68% (n=698) of respondents were dairy producers, and the remaining respondents represented veterinarians, university researchers, government personnel, and other allied industries. Participants were asked to identify their top 3 management and disease priorities from 2 lists offered. Topics were subsequently ranked from highest to lowest using 3 different ranking methods based on points: 5-3-1 (5 points for first priority, 3 for second, and 1 for first), 3-2-1, and 1-1-1 (equal ranking). The 5-3-1 point system was selected because it minimized the number of duplicate point scores. Stakeholder groups showed general agreement with the top management issue identified as animal welfare and the number one health concern as lameness. Other areas identified as priorities were reproductive health, antibiotic use, bovine viral diarrhea, and Staphylococcus aureus mastitis with these rankings influenced by region, herd size, and stakeholder group. This is the first national comprehensive assessment of priorities undertaken in the Canadian dairy industry and will assist researchers, policymakers, program developers, and funding agencies make future decisions based on direct industry feedback. PMID- 27720161 TI - Effect of pasture versus indoor feeding systems on raw milk composition and quality over an entire lactation. AB - The aim of this study was to investigate the effects of different feeding systems on milk quality and composition. Fifty-four multiparous and primiparous Friesian lactating cows were divided into 3 groups (n=18) to study the effects of 3 feeding systems over a full lactation. Group 1 was housed indoors and offered a total mixed ration diet (TMR), group 2 was maintained outdoors on a perennial ryegrass pasture (referred to as grass), and group 3 was also grazed outdoors on a perennial ryegrass/white clover pasture (referred to as clover). Bulk milk samples were collected from each group at morning and afternoon milkings once weekly from March 11 to October 28 in 2015. Milk from pasture-fed cows (grass and clover) had significantly higher concentrations of fat, protein, true protein, and casein. The pasture feeding systems induced significantly higher concentrations of saturated fatty acids C11:0, C13:0, C15:0, C17:0, C23:0, and unsaturated fatty acids C18:2n-6 trans, C18:3n-3, C20:1, and C20:4n-6 and a greater than 2-fold increase in the conjugated linoleic acid C18:2 cis-9,trans-11 content of milk compared with that of the TMR feeding system. The TMR feeding system resulted in milks with increased concentrations of C16:0, C18:2n-6 cis, C18:3n-6 cis, C22:0 C22:1n-9, and C18:2 cis-10,trans-12. Principal component analysis of average fatty acid profiles showed clear separation of milks from the grazed pasture-based diets to that of a TMR system throughout lactation, offering further insight into the ability to verify pasture-derived milk by fatty acid profiling. PMID- 27720162 TI - Is subclinical hypothyroidism associated with lower live birth rates in women who have experienced unexplained recurrent miscarriage? AB - Thyroid disorders have been associated with recurrent miscarriage. Little evidence is available on the influence of subclinical hypothyroidism on live birth rates. In this cohort study, women who had experienced miscarriage and subclinical hypothyroidism (defined as thyroid-stimulating hormone >97.5th percentile mU/l with a normal thyroxine level) were investigated; the control group included women who had experienced recurrent miscarriage and normal thyroid function. Multivariable logistic regression was used to investigate the association of subclinical hypothyroidism. Data were available for 848 women; 20 (2.4%) had subclinical hypothyroidism; 818 women (96%) had euthyroidism; and 10 (1.2%) had overt hypothyroidism. The live birth rate was 45% in women with subclinical hypothyroidism and 52% in euthyroid women (OR 0.69, 95% CI 0.28 to 1.71). The ongoing pregnancy rate was 65% versus 69% (OR 0.82, 95% CI 0.32 to 2.10) and the miscarriage rate was 35% versus 28% (OR 1.43, 95% CI 0.56 to 3.68), respectively. No differences were found when thyroid stimulating hormone 2.5 mU/l was used as cut-off level to define subclinical hypothyroidism. In women with unexplained miscarriage, no differences were found in live birth, ongoing pregnancy and miscarriage rates between women with subclinical hypothyroidism and euthyroid women. PMID- 27720163 TI - The effect of intravenous immunoglobulin passive immunotherapy on unexplained recurrent spontaneous abortion: a meta-analysis. AB - The aim of this study was to investigate the effect of passive immunotherapy using intravenous immunoglobulin (IVIG) on unexplained recurrent spontaneous abortion (RSA). Live birth rates were analysed and binary data were calculated using risk ratio and 95% confidence interval. Meta-analysis of 11 studies showed that the difference in the live birth rate between the IVIG treatment and placebo groups was on the margin of significance (RR = 1.25, 95% CI 1.00 to 1.56, P = 0.05). Both cumulative and trial sequential meta-analyses indicated potential beneficial effect of IVIG but the evidence was inconclusive. Subgroup analysis showed that the live birth rate in primary (RR = 0.88, 95% CI 0.71 to 1.07) and secondary (RR = 1.26, 95% CI 0.99 to 1.61) RSA patients was not significantly different between the IVIG and placebo groups. Live birth rate was significantly different when IVIG was administered before conception (RR = 1.67, 95% CI 1.30 to 2.14, P < 0.0001) but not after implantation (RR = 1.10, 95% CI 0.93 to 1.29). Evidence is insufficient to support the beneficial effects of IVIG on an unexplained RSA. Further high quality studies are needed to elucidate the effectiveness of IVIG. PMID- 27720164 TI - Survival of Patients With Advanced or Metastatic Renal Cell Carcinoma in Routine Practice Differs From That in Clinical Trials-Analyses From the German Clinical RCC Registry. AB - INTRODUCTION: Because "real-life" patients often do not meet the strict eligibility criteria of clinical trials, we assessed the trial eligibility of patients with advanced or metastatic renal cell carcinoma (mRCC) in routine practice and compared the survival of "trial-ineligible" and potentially "trial eligible" patients. PATIENTS AND METHODS: The present prospective, multicenter German cohort study is recruiting patients from 110 oncology/urology outpatient centers and hospitals at initiation of systemic first-line treatment. The demographic, clinical, treatment, and survival data were collected. We defined patients as "trial-ineligible" when >= 1 exclusion criterion (Karnofsky performance status < 80%, hemoglobin less than the lower limit of normal, non clear cell carcinoma histology) was documented. Otherwise, the patients were considered "trial-eligible". RESULTS: Of 732 patients included, 57% were classified as "trial-ineligible". Overall, the median first-line progression-free survival (PFS) was 7.9 months (95% confidence interval [CI], 6.9-8.9 months). The median first-line PFS of "trial-eligible" and "trial-ineligible" patients was 11.0 months (95% CI, 9.6-13.1 months) and 5.3 months (95% CI, 4.6-6.5 months), respectively. The median OS of the "trial-eligible" and "trial-ineligible" patients was 26.0 months (95% CI, 22.1-29.7 months) and 12.6 months (95% CI, 10.6 15.8 months), respectively. CONCLUSION: Our data suggest that patients in routine practice differ from patients treated in clinical trials and that almost 60% of mRCC patients in German routine practice would be ineligible for participation in clinical trials. While their first-line PFS and OS were shorter than those of "trial-eligible" patients, the PFS and OS of "trial-eligible" patients were comparable with the results from clinical trials. Physicians should be aware of these differences when discussing treatment options and outcome expectations with patients. PMID- 27720165 TI - Policy interventions related to medicines: Survey of measures taken in European countries during 2010-2015. AB - BACKGROUND: Policy-makers can use a menu of pharmaceutical policy options. This study aimed to survey these measures that were implemented in European countries between 2010 and 2015. METHODS: We did bi-annual surveys with competent authorities of the Pharmaceutical Pricing and Reimbursement Information network. Additionally, we consulted posters produced by members of this network as well as further published literature. Information on 32 European countries (all European Union Member States excluding Luxembourg; Iceland, Norway, Serbia, Switzerland, Turkey) was included. RESULTS: 557 measures were reported between January 2010 and December 2015. The most frequently mentioned measure was price reductions and price freezes, followed by changes in patient co-payments, modifications related to the reimbursement lists and changes in distribution remuneration. Most policy measures were identified in Portugal, Greece, Belgium, France, the Czech Republic, Iceland, Spain and Germany. 22% of the measures surveyed could be classified as austerity. CONCLUSIONS: Countries that were strongly hit by the financial crisis implemented most policy changes, usually aiming to generate savings and briefly after the emergence of the crisis. Improvements in the economic situation tended to lead to an easing of austerity measures. Countries also implemented policies that aimed to enhance enforcement of existing measures and increase efficiency. PMID- 27720166 TI - Cardiac surgery in low-income settings: 10 years of experience from two countries. AB - BACKGROUND: Access to cardiac surgery is limited in low-income settings, and data on patient outcomes are scarce. AIMS: To assess characteristics, surgical procedures and outcomes in patients undergoing open-heart surgery in low-income settings. METHODS: This was a cohort study (2001-2011) in two low-income countries, Cambodia and Mozambique, where cardiac surgery had been promoted by visiting non-governmental organizations. RESULTS: In Cambodia and Mozambique, respectively, 1332 and 767 consecutive patients were included; 547 (41.16%) and 385 (50.20%) were men; median age at first surgery was 11 years (interquartile range [IQR] 4-14) and 11 years (IQR 3-18); rheumatic heart disease affected 490 (36.79%) and 268 (34.94%) patients; congenital heart disease (CHD) affected 834 (62.61%) and 390 (50.85%) patients, with increasingly more CHD patients over time (P<0.001); and the number of patients lost to follow-up reached 741 (55.63%) and 112 (14.6%) at 30 days. A total of 249 (32.46%) patients were lost to follow-up in Mozambique, remoteness being the only influencing factor (P<0.001). Among patients with known vital status, the early (<30 days) postoperative mortality rate was 6.10% (n=40) in Mozambique and 3.05% (n=18) in Cambodia. Overall, 109 (8.18%) patients in Cambodia and 94 (12.26%) patients in Mozambique underwent re do surgery. In Mozambique, a further 50/518 (9.65%) patients died at a median of 23months (IQR 7-43); in Cambodia, a further 34/591 (5.75%) patients died at a median of 11.5months (IQR 6-54.5). CONCLUSIONS: Cardiac surgery is feasible in low-income countries with acceptable in-hospital mortality and proof of capacity building. Patient outcomes after cardiac surgery in low-income countries remain unknown, given the strikingly high numbers of lost to follow-up. PMID- 27720167 TI - Coronary artery bypass grafting for left main disease and the risk of stroke: Incidence, aetiology and prevention. AB - This review explores the association between left main disease and the increased risk of perioperative stroke following coronary artery bypass grafting, specifically addressing the potential underlying mechanisms and its potential prevention. In particular, this correlation appears stronger for patients with left main disease when compared to patients with isolated triple vessel disease. Even though evidence on this topic is limited and of modest quality, there appears to be a significant association between ascending aorta atherosclerosis and coronary artery disease. Furthermore, there seems to be a relationship between the severity and extent of carotid artery stenosis and coronary artery disease. Carotid artery disease is itself associated with atherosclerosis of the ascending aorta, a well-recognised risk factor for postoperative atheroembolic stroke. The association between left main disease, ascending aorta atherosclerosis and carotid artery stenosis may reflect an increased systemic atherosclerotic burden and hence explain, at least partially, the higher risk of perioperative cerebrovascular events. Potential pre-, intra- and post-operative strategies for stroke prevention are discussed. PMID- 27720168 TI - Challenges for stem cell-based "regenerative prosthodontics".

AB - Drug-induced sleep endoscopy (DISE) is an upper airway evaluation technique in which fiberoptic examination is performed under conditions of unconscious sedation. Unique information obtained from this 3-dimensional examination of the airway potentially provides additive benefits to other evaluation methods to guide treatment selection. This article presents recommendations regarding DISE technique and the VOTE Classification system for reporting DISE findings and reviews the evidence concerning DISE test characteristics and the association between DISE findings and treatment outcomes.

AB - Low temperature and high hydrostatic pressure (HHP) are two of the most remarkable environmental factors influencing deep-sea ecosystem. The adaptive mechanisms of microorganisms which live in these extreme environments to low temperature and high pressure warrant investigation. In this study, the global gene expression patterns of the deep-sea bacterium Shewanella piezotolerans WP3 in response to cold (0 degrees C) and HHP (50 MPa) shock were evaluated through DNA microarray analysis. Results revealed that 22, 66, and 106 genes were differentially expressed after WP3 was respectively exposed to cold shock for 30, 60, and 90 min. Of these genes, 16 genes were identified as common differentially expressed genes (DEGs). After 30 min and 120 min of HHP shock, 5 and 10 genes were respectively identified as DEGs. The hierarchical clustering analysis of the DEG pattern indicated that WP3 may employ different adaptive strategies to cope with cold and HHP shock stress. Taken together, our study provided a transcriptome resource for deep-sea bacterial responses to cold and HHP stress. This study also established a basis for further investigations on environmental adaptive mechanisms utilized by benthic bacteria.

AB - New composite matrices have been suggested for the analysis of mixtures of different synthetic organic compounds (N-containing heterocycles and erectile dysfunction drugs) by thin layer chromatography/matrix-assisted laser desorption ionization time-of-flight mass spectrometry (TLC/MALDI-TOF). Different mixtures of classical MALDI matrices and graphite particles dispersed in glycerol were used for the registration of MALDI mass spectra directly from TLC plates after analytes separation. In most of cases, the mass spectra possessed [M+H]+ ions; however, for some analytes only [M+Na]+ and [M+K]+ ions were observed. These ions have been used to generate visualized TLC chromatograms. The described approach increases the desorption/ionization efficiencies of analytes separated by TLC, prevent spot blurring, simplifies and decrease time for sample preparation. PMID- 27720172 TI - Nonlinear model predictive control applied to the separation of praziquantel in simulated moving bed chromatography. AB - An adaptive nonlinear model predictive control of a simulated moving bed unit for the enantioseparation of praziquantel is presented. A first principle model was applied at the proposed purity control scheme. The main concern about this kind of model in a control framework is in regard to the computational effort to solve it; however, a fast enough solution was achieved. In order to evaluate the controller's performance, several cases were simulated, including external pumps and switching valve malfunctions. The problem of plant-model mismatch was also investigated, and for that reason a parameter estimation step was introduced in the control strategy. In every studied scenario, the controller was able to maintain the purity levels at their set points, which were set to 99% and 98.6% for extract and raffinate, respectively. Additionally, fast responses and smooth actuation were achieved. PMID- 27720173 TI - Simulation and experimental study of enzyme and reactant mixing in capillary electrophoresis based on-line methods. AB - The establishment of an efficient reaction mixture represents a crucial part of capillary electrophoresis based on-line enzymatic assays. For ketamine N demethylation to norketamine mediated by the cytochrome P450 3A4 enzyme, mixing of enzyme and reactants in the incubation buffer at physiological pH was studied by computer simulation. A dynamic electrophoretic simulator that encompasses Taylor-Aris diffusivity which accounts for dispersion due to the parabolic flow profile associated with pressure driven flow was utilized. The simulator in the diffusion mode was used to predict transverse diffusional reactant mixing occurring during hydrodynamic plug injection of configurations featuring four and seven plugs. The same simulator in the electrophoretic mode was applied to study electrophoretic reactant mixing caused by voltage application in absence of buffer flow. Resulting conclusions were experimentally verified with enantioselective analysis of norketamine in a background electrolyte at low pH. Furthermore, simulations visualize buffer changes that occur upon power application between incubation buffer and background electrolyte and have an influence on the reaction mixture. PMID- 27720174 TI - Towards a chromatographic similarity index to establish localized quantitative structure-retention models for retention prediction: Use of retention factor ratio. AB - Quantitative Structure-Retention Relationships (QSRR) have the potential to speed up the screening phase of chromatographic method development as the initial exploratory experiments are replaced by prediction of analyte retention based solely on the structure of the molecule. The present study offers further proof of-concept of localized QSRR modelling, in which the retention of any given compound is predicted using only the most chromatographically similar compounds in the available dataset. To this end, each compound in the dataset was sequentially removed from the database and individually utilized as a test analyte. In this study, we propose the retention factor k as the most relevant chromatographic similarity measure and compare it with the Tanimoto index, the most popular similarity measure based on chemical structure. Prediction error was reduced by up to 8 fold when QSRR was based only on chromatographically similar compounds rather than using the entire dataset. The study therefore shows that the design of a practically useful structural similarity index should select the same compounds in the dataset as does the k-similarity filter in order to establish accurate predictive localized QSRR models. While low average prediction errors (Mean Absolute Error (MAE)<0.5min) and slopes of the regression lines through the origin close to 1.00 were obtained using k-similarity searching, the use of the structural Tanimoto similarity index, considered as the gold standard in Quantitative Structure-Activity Relationships (QSAR) studies, generally resulted in much higher prediction errors (MAE>1min) and significant deviations from the reference slope of 1.0. The Tanomoto similarity index therefore appears to have limited general utility in QSRR studies. Future studies therefore aim at designing a more appropriate chromatographic similarity index that can then be applied for unknown compounds (that is, compounds which have not been tested previously on the chromatographic system used, but for which the chemical structures are known). PMID- 27720175 TI - Determination of 3'-phosphoadenosine-5'-phosphosulfate in cells and Golgi fractions using hydrophilic interaction liquid chromatography-mass spectrometry. AB - 3'-Phosphoadenosine-5'-phosphosulfate (PAPS) is a key player in the sulfation of biomolecules, but methods for selective measurements are lacking. A liquid chromatography-mass spectrometry (LC-MS) approach for measuring PAPS was developed. A central feature of the method was employing hydrophilic interaction liquid chromatography (HILIC), which is highly suited for separating very polar/charged compounds, and is compatible with electrospray MS. Using simple instrumentation, the analysis time per sample was below 10min and the method was characterized by easy sample preparation. The method was used to monitor decreasing levels of PAPS as function of sodium chlorate treatment (an inhibitor of PAPS synthesis) in whole-cell lysates as well as Golgi-fractions. The method allowed PAPS to be chromatographically separated from ADP and ATP, which can interfere with measurements if a less resolving LC-MS method is used. PMID- 27720176 TI - Presentations. PMID- 27720177 TI - Senescence of T Lymphocytes: Implications for Enhancing Human Immunity. AB - As humans live longer, a central concern is to find ways to maintain their health as they age. Immunity declines during ageing, as shown by the increased susceptibility to infection by both previously encountered and new pathogens and by the decreased efficacy of vaccination. It is therefore crucial to understand the mechanisms responsible for this decrease in immunity and to develop new strategies to enhance immune function in older humans. We discuss here how the induction of senescence alters leukocyte, and specifically T cell, function. An emerging concept is that senescence and nutrient sensing-signalling pathways within T cells converge to regulate functional responses, and the manipulation of these pathways may offer new ways to enhance immunity during ageing. PMID- 27720179 TI - Two new mutations of the CLMP gene identified in a newborn presenting congenital short-bowel syndrome. AB - Congenital short-bowel syndrome (CSBS) is a rare neonatal pathology associated with poor prognosis and high mortality rate. We describe a newborn presenting CSBS intestinal malrotation and chronic intestinal pseudo-obstruction syndrome (CIPS), compound heterozygous for two previously unreported heterozygous mutations in Coxsackie and adenovirus receptor-like membrane protein (CLMP) gene, one in intron 1 (c.28+1G>C), the other on exon 4 (c502C>T, p.R168X). Both mutations are predicted to be pathogenic, leading to impaired splicing and the appearance of a premature stop codon, respectively. Our case is remarkable in that it concerns two heterozygous truncating mutations associated with a good clinical prognosis with a favorable cerebral and gastrointestinal outcome and a substantial enteral input at 8 months of age, despite a small intestine measuring only 35cm. PMID- 27720180 TI - Feasibility of a low concentration test bolus in CT angiography. AB - AIM: To investigate the feasibility of using a low-concentration test bolus in abdominal aorta computed tomography (CT) angiography (CTA). MATERIALS AND METHODS: In 10 patients referred for CTA of the abdominal aorta with a body mass index (BMI) <=28 kg/m2, a standard test bolus of 10 ml contrast medium (CM; 350 mg iodine/ml) was compared with a low-concentration test bolus (5 ml CM; 350 mg iodine/ml; 1:1 diluted with saline) in terms of time to peak enhancement (tPE) and peak enhancement (PE). RESULTS: No significant differences were found between the standard and low-concentration test bolus in terms of tPE and PE. CONCLUSIONS: A low-concentration test bolus (5 ml, 1:1 diluted with saline) is feasible in patients with a BMI <=28 kg/m2. PMID- 27720178 TI - Child-onset and adolescent-onset acquired thrombotic thrombocytopenic purpura with severe ADAMTS13 deficiency: a cohort study of the French national registry for thrombotic microangiopathy. AB - BACKGROUND: Thrombotic thrombocytopenic purpura is a rare thrombotic microangiopathy, related to a severe ADAMTS13 deficiency (a disintegrin and metalloprotease with thromboSpondin type 1 repeats, member 13; activity <10% of normal). Childhood-onset thrombotic thrombocytopenic purpura is very rare and initially often misdiagnosed, especially when ADAMTS13 deficiency is acquired (ie, not linked to inherited mutations of the ADAMTS13 gene). We aimed to investigate initial presentation, management, and outcome of acquired thrombotic thrombocytopenic purpura in children. METHODS: Between Jan 1, 2000, and Dec 31, 2015, we studied a cohort of patients with child-onset and adolescent-onset acquired thrombotic thrombocytopenic purpura included in the French national registry for thrombotic microangiopathies at presentation and during follow up. The inclusion criteria were: first episode before age 18 years; ADAMTS13 activity less than 10% of normal at presentation; positive anti-ADAMTS13 autoantibodies during an episode, or a recovery of ADAMTS13 activity in remission, or both. ADAMTS13 activity and anti-ADAMTS13 autoantibodies were investigated by a central laboratory, and medical records were extensively reviewed to collect clinical and biological features with a standardised form. This study is registered with ClinicalTrials.gov, number NCT00426686. FINDINGS: We enrolled 973 patients with childhood-onset thrombotic microangiopathy, of whom 74 had a severe ADAMTS13 deficiency (activity <10%) at presentation. 24 patients had an inherited thrombotic thrombocytopenic purpura also known as Upshaw-Schulman syndrome and five did not have follow-up data available, thus 45 children had acquired thrombotic thrombocytopenic purpura and were included in our database at presentation. 25 (56%) patients had idiopathic disease and 20 (44%) had miscellaneous associated clinical conditions. At diagnosis, median age was 13 years (IQR 7-16, range 4 months-17 years), with a sex ratio of 2.5 girls to 1 boy. Anti-ADAMTS13 autoantibodies were positive in 37 (82%) of 45 patients (24 [96%] of 25 idiopathic cases and 13 [65%] of 20 non-idiopathic cases). 39 (87%) of 45 patients were given plasma therapy and 21 (47%) received additional rituximab. Four (9%) children died after the first thrombotic thrombocytopenic purpura episode. Long-term follow up of the 41 survivors showed that ten (24%) patients relapsed and systemic lupus erythematosus occurred in two (5%) patients. Preemptive rituximab was used in seven (17%) of 41 patients with acquired thrombotic thrombocytopenic purpura. INTERPRETATION: Our study shows that child onset and adolescent-onset acquired thrombotic thrombocytopenic purpura have specific clinical, biological and therapeutic features. Long-term follow-up is crucial to prevent relapses of the disease, to identify the occurrence of autoimmune disorders, and to evaluate consequences on social life. Child-onset and adolescent-onset acquired thrombotic thrombocytopenic purpura is a crucial diagnosis in the field of paediatric haematologic cytopenias because it is a life threatening disease requiring a specific management.

PMID- 27720181 TI - Association between ventricular filling patterns and the extent of late enhancement on magnetic resonance imaging in patients with hypertrophic cardiomyopathy. AB - OBJECTIVE: To explore the relationship between ventricular filling curves and the extent of late enhancement on cardiac magnetic resonance imaging (MRI) in patients with hypertrophic cardiomyopathy. MATERIAL AND METHODS: We retrospectively included consecutive patients with suspected and/or confirmed hypertrophic cardiomyopathy and a control group of patients matched for age and sex who underwent cardiac MRI with evaluation of late enhancement. Among other determinations, we evaluated the following parameters on cine sequences: peak filling rate, time to the first peak filling rate, and filling rate normalized to the filling volume. RESULTS: Late enhancement was observed in 29 (73%) of the 40 patients with hypertrophic cardiomyopathy. The normalized peak filling rate was significantly lower in patients with late enhancement (4.9 +/- 1.6 in those with hypertrophic cardiomyopathy positive for late enhancement vs. 5.8 +/- 2.2 in those with hypertrophic cardiomyopathy negative for late enhancement vs. 6.3 +/- 1.5 in controls, p = 0.008) and the time to peak filling was longer in patients with late enhancement (540.6 +/- 89.7 ms vs. 505.5 +/- 99.3 ms in those with hypertrophic cardiomyopathy negative for late enhancement vs. 486.9 +/- 86.3 ms in controls, p = 0.02). When the population was stratified into three groups in function of the normalized peak filling rate, significant differences were observed among groups for age (p = 0.002), mean wall thickness (p = 0.036), and myocardial mass (p = 0.046) and atrial dimensions, whereas no significant differences with respect to late enhancement were seen. CONCLUSIONS: In patients with hypertrophic cardiomyopathy, we found a significant association between ventricular filling patterns and age, wall thicknesses, and atrial dimensions, but not with the extent of late enhancement.

PMID- 27720182 TI - Plate fixation in periprosthetic femur fractures Vancouver type B1-Trochanteric hook plate or subtrochanterical bicortical locking? AB - INTRODUCTION: Proximal plate fixation in periprosthetic femur fractures can be improved by plate anchorage in the greater trochanter (lateral tension band principle) or bicortical locking screw placement beside the prosthesis stem in an embracement configuration. Both concepts were compared in a biomechanical test using a femoral hook plate (hook) or a locking attachment plate (LAP). METHODS: After bone mineral density (BMD) measurement in the greater trochanter, six pairs of fresh frozen human femora were assigned to two groups and instrumented with cemented hip endoprostheses. A transverse osteotomy was set distal to the tip of the prosthesis, simulating a Vancouver B1 fracture. Each pair was instrumented using a plate tensioner with either hook or LAP construct. Cyclic testing (2Hz) with physiologic profile and monotonically increasing load was performed until catastrophic failure. Plate stiffness was compared in a four-point-bending-test. Paired student's-t-test was used for statistical evaluation (p<0.05). RESULTS: Mean BMD was 250mgHA/ccm+/-47. The hook construct exhibited a significantly (p=0.015) lower number of cycles and load to failure (26'177cycles+/-2777; 3'118N+/-778) correlating significantly with BMD (R2=0.83; p=0.04) compared to the LAP construct (37'423cycles+/-5'299; 4'242N+/-1'030) (R2=0.71;p=0.11). BMD was a significant covariate (p=0.01). Plate stiffness was in a comparable range (hook Plate 468N/mm+/-7; LCP 445N/mm+/-6). CONCLUSION: Subtrochanterically placed LAP provides an increased fixation strength under repetitive loading compared to hook plate fixation in the greater trochanter. Trochanteric fixation is highly BMD dependent and may be restricted to major greater trochanteric involvement requiring stabilization.

PMID- 27720186 TI - Role of Soft-Tissue Heterogeneity in Computational Models of Deep Brain Stimulation. AB - BACKGROUND: Bioelectric field models of deep brain stimulation (DBS) are commonly utilized in research and industrial applications. However, the wide range of different representations used for the human head in these models may be responsible for substantial variance in the stimulation predictions. OBJECTIVE: Determine the relative error of ignoring cerebral vasculature and soft-tissue heterogeneity outside of the brain in computational models of DBS. METHODS: We used a detailed atlas of the human head, coupled to magnetic resonance imaging data, to construct a range of subthalamic DBS volume conductor models. We incrementally simplified the most detailed base model and quantified changes in the stimulation thresholds for direct activation of corticofugal axons. RESULTS: Ignoring cerebral vasculature altered predictions of stimulation thresholds by <10%, whereas ignoring soft-tissue heterogeneity outside of the brain altered predictions between -44 % and 174%. CONCLUSIONS: Heterogeneity in the soft tissues of the head, if unaccounted for, introduces a degree of uncertainty in predicting electrical stimulation of neural elements that is not negligible and thereby warrants consideration in future modeling studies. PMID- 27720187 TI - Elements of cultural competence in an Australian Aboriginal maternity program. AB - BACKGROUND: Pregnancy, labour and neonatal health outcomes for Australian Aboriginal women and their infants are frequently worse than those of the general population. Provision of culturally competent services may reduce these differences by improving access to timely and regular antenatal care. In an effort to address these issues, the Aboriginal Maternity Group Practice Program commenced in south metropolitan Perth, Western Australia, in 2011. The program employed Aboriginal Grandmothers, Aboriginal Health Officers and midwives working in a partnership model with pre-existing maternity services in the area. AIM: To identify elements of the Aboriginal Maternity Group Practice Program that contributed to the provision of a culturally competent service. METHODS: The Organisational Cultural Competence Assessment Tool was used to analyse qualitative data obtained from surveys of 16 program clients and 22 individuals from partner organisations, and interviews with 15 staff. FINDINGS: The study found that the partnership model positively impacted on the level of culturally appropriate care provided by other health service staff, particularly in hospitals. Two-way learning was a feature. Providing transport, team home visits and employing Aboriginal staff improved access to care. Grandmothers successfully brought young pregnant women into the program through their community networks, and were able to positively influence healthy lifestyle behaviours for clients. CONCLUSION: Many elements of the Aboriginal Maternity Group Practice Program contributed to the provision of a culturally competent service. These features could be considered for inclusion in antenatal care models under development in other regions with culturally diverse populations. PMID- 27720184 TI - Geriatric assault victims treated at U.S. trauma centers: Five-year analysis of the national trauma data bank. AB - INTRODUCTION: While geriatric trauma patients have begun to receive increased attention, little research has investigated assault-related injuries among older adults. Our goal was to describe characteristics, treatment, and outcomes of geriatric assault victims and compare them both to geriatric victims of accidental injury and younger assault victims. PATIENTS AND METHODS: We conducted a retrospective analysis of the 2008-2012 National Trauma Data Bank. We identified cases of assault-related injury admitted to trauma centers in patients aged >=60 using the variable "intent of injury." RESULTS: 3564 victims of assault related injury in patients aged >=60 were identified and compared to 200,194 geriatric accident victims and 94,511 assault victims aged 18-59. Geriatric assault victims were more likely than geriatric accidental injury victims to be male (81% vs. 47%) and were younger than accidental injury victims (67+/-7 vs. 74+/-9 years). More geriatric assault victims tested positive for alcohol or drugs than geriatric accident victims (30% vs. 9%). Injuries for geriatric assault victims were more commonly on the face (30%) and head (27%) than for either comparison group. Traumatic brain injury (34%) and penetrating injury (32%) occurred commonly. The median injury severity score (ISS) for geriatric assault victims was 9, with 34% having severe trauma (ISS>=16). Median length of stay was 3 days, 39% required ICU care, and in-hospital mortality was 8%. Injury severity was greater in geriatric than younger adult assault victims, and, even when controlling for injury severity, in-hospital mortality, length of hospitalization, and need for ICU-level care were significantly higher in older adults. CONCLUSIONS: Geriatric assault victims have characteristics and injury patterns that differ significantly from geriatric accidental injury victims. These victims also have more severe injuries, higher mortality, and poorer outcomes than younger victims. Additional research is necessary to improve identification of these victims and inform treatment strategies for this unique population. PMID- 27720188 TI - Usefulness of High-Frequency Ultrasound in the Classification of Histologic Subtypes of Primary Basal Cell Carcinoma. AB - INTRODUCTION: Incisional biopsy may not always provide a correct classification of histologic subtypes of basal cell carcinoma (BCC). High-frequency ultrasound (HFUS) imaging of the skin is useful for the diagnosis and management of this tumor. OBJECTIVES: The main aim of this study was to compare the diagnostic value of HFUS compared with punch biopsy for the correct classification of histologic subtypes of primary BCC. We also analyzed the influence of tumor size and histologic subtype (single subtype vs. mixed) on the diagnostic yield of HFUS and punch biopsy. METHODS: Retrospective observational study of primary BCCs treated by the Dermatology Department of Hospital Costa del Sol in Marbella, Spain, between october 2013 and may 2014. Surgical excision was preceded by HFUS imaging (Dermascan C(c), 20-MHz linear probe) and a punch biopsy in all cases. We compared the overall diagnostic yield and accuracy (sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV]) of HFUS and punch biopsy against the gold standard (excisional biopsy with serial sections) for overall and subgroup results. RESULTS: We studied 156 cases. The overall diagnostic yield was 73.7% for HFUS (sensitivity, 74.5%; specificity, 73%) and 79.9% for punch biopsy (sensitivity, 76%; specificity, 82%). In the subgroup analyses, HFUS had a PPV of 93.3% for superficial BCC (vs. 92% for punch biopsy). In the analysis by tumor size, HFUS achieved an overall diagnostic yield of 70.4% for tumors measuring 40mm2 or less and 77.3% for larger tumors; the NPV was 82% in both size groups. Punch biopsy performed better in the diagnosis of small lesions (overall diagnostic yield of 86.4% for lesions <=40mm2 vs. 72.6% for lesions >40mm2). CONCLUSIONS: HFUS imaging was particularly useful for ruling out infiltrating BCCs, diagnosing simple, superficial BCCs, and correctly classifying BCCs larger than 40mm2.

AB - Purulent pericarditis seldom occurs in Western countries, yet its mortality rate remains high between 20 and 35 % despite early treatment. We report the case of a 43-year-old patient admitted in the intensive cardiologic care unit with a pre tamponade, requiring an immediate percutaneous pericardiocentesis allowing the drainage of a purulent effusion. Evolution with antibiotic therapy adapted according to the bacteriological findings was favorable and 3-months follow-up shows a near complete regression of the effusion. This case recalls us this rare diagnosis entity and illustrates the possibility of a mere percutaneous pericardial drainage with the condition of a strict medical surveillance.

AB - To treat a worldwide common ear disease (OME), a device allowing fast grommet tube insertion has been designed in our earlier works (Gao et al., 2015 [1] and Liang et al., 2013 [2]). However, the instrument has to be manually placed as close as to the Tympanic Membrane before the insertion procedures. To realize a fully automated surgical process, the instrument shall be automatically manipulated to align to the axial direction of ear canal and proceed to complete the surgery. A vision-based servomechanism is proposed to solve the path planning problem. A fuzzy-gain-scheduled controller is proposed to minimize the projection error based on the image detection and the proximity measurement. The proposed controller is proven to outperform the traditional PI controller in pre-clinical trials. PMID- 27720192 TI - Is anterior glenoid bone block position reliably assessed by standard radiography? A cadaver study. AB - BACKGROUND: Standard radiography with an antero-posterior view and Bernageau's glenoid profile view is the method most widely reported in the literature to assess coracoid bone block position and fusion. OBJECTIVE: The aim of this cadaver study was to determine whether the antero-posterior and Bernageau's radiographs provide a reliable and reproducible evaluation of the position of a coracoid bone block and its fixation screws. METHOD: An isolated scapula showing no evidence of osteoarthritis or other abnormalities was used. The coracoid process was transferred to the anterior glenoid rim. Fixation was with two slightly diverging malleolar screws, chosen of different sizes for ease of identification. Computed tomography (CT) was performed as the reference imaging technique. The standard radiographs were then obtained, using fluoroscopy to accurately position the scapula for the antero-posterior and Bernageau's views. This position was defined as 0 degrees , and radiographs were taken at angles of 5 degrees , 10 degrees , and 15 degrees in all three planes. All radiographs were taken during a single session to ensure that the distance separating the tube from the scapula remained unchanged. The images were exported to OsiriX for analysis. We measured the angles formed by the screws and the glenoid surface, as well as bone block position and overhang. Finally, we used 1-mm thick disks to evaluate bone-to-bone contact. RESULTS: No correlations were found between values by CT and by standard radiography (both views) for the screw angles or overhang. A space<=1mm between the neck of the scapula and the bone block was not visible on the standard radiographs in any of the positions. CONCLUSION: Standard radiography does not provide an accurate analysis of bone block position or bone to-bone contact. CT is needed to assess bone block and screw position and bone-to bone contact. LEVEL OF EVIDENCE: Level III. PMID- 27720190 TI - Past Roadblocks and New Opportunities in Transcription Factor Network Mapping. AB - One of the principal mechanisms by which cells differentiate and respond to changes in external signals or conditions is by changing the activity levels of transcription factors (TFs). This changes the transcription rates of target genes via the cell's TF network, which ultimately contributes to reconfiguring cellular state. Since microarrays provided our first window into global cellular state, computational biologists have eagerly attacked the problem of mapping TF networks, a key part of the cell's control circuitry. In retrospect, however, steady-state mRNA abundance levels were a poor substitute for TF activity levels and gene transcription rates. Likewise, mapping TF binding through chromatin immunoprecipitation proved less predictive of functional regulation and less amenable to systematic elucidation of complete networks than originally hoped. This review explains these roadblocks and the current, unprecedented blossoming of new experimental techniques built on second-generation sequencing, which hold out the promise of rapid progress in TF network mapping. PMID- 27720193 TI - Peri-articular local infiltration analgesia versus femoral nerve block for postoperative pain control following anterior cruciate ligament reconstruction: Prospective, comparative, non-inferiority study. AB - INTRODUCTION: Femoral nerve block (FNB) is considered as a major advance in anterior cruciate ligament (ACL) reconstruction as it reduces the need for parenteral opioids. However, the incidence of transient or even permanent neurological deficits due to the FNB is estimated at 1.94% after knee surgery. The primary objective of this study was to compare local infiltration analgesia (LIA) to FNB during ACL reconstruction procedures. The study hypothesis was that LIA was not less effective than FNB on early postoperative pain. PATIENTS AND METHODS: A retrospective analysis of data collected prospectively in the FAST cohort included a series of continuous patients who underwent primary repair for isolated ACL with a hamstring graft in 2013-2014. Changes in our anesthesia practices over time allowed us to form three successive groups: Group 1 - FNB, Group 2 - FNB+LIA, Group 3 - LIA only. Ultrasound-guided FNB was done pre operatively. The LIA was done at the end of the procedure by the surgeon with systematic infiltration of all skin incisions and the hamstring donor site; no intra-articular injections were performed. The primary endpoint was the average early postoperative pain (Days 0-3) described by the patient on a visual analogue scale (0-10). Sample size calculation pointed to 36 subjects being needed per group for a non-inferiority study. RESULTS: The study involved 126 patients: G1=42, G2=38, G3=46. The patients were comparable at enrolment. The average early postoperative pain levels were 3.1+/-2.4, 2.8+/-2.0 and 2.5+/-2.2, respectively (P=0.66). A trend toward higher intake of tramadol was noted in the LIA group on D0 to D3, with a significant trend test on Day 1 (P=0.03) and Day 2 (P=0.02). CONCLUSION: After reconstruction of isolated ACL tears with a hamstring graft, FNB is not more effective than LIA on patients' early postoperative pain. Patients who received a FNB consumed significantly less opioid-like analgesics. LEVEL OF EVIDENCE: III - Prospective, comparative, non-randomized study.

AB - BACKGROUND: The efficacy of laparoscopic Roux-en-Y gastric bypass (LRYGB) in type 2 diabetes mellitus (T2D) is closely associated with the preoperative body mass index (BMI) of the patient. There is a lack of long-term and large sampling evidence on the efficacy of LRYGB in T2D patients with low BMI in China. OBJECTIVES: This retrospective study aimed to evaluate the efficacy of surgical treatment in a Chinese population with T2D (especially patients with BMI<27.5 kg/m2). SETTING: University-affiliated hospital, China METHODS: Seventy-eight patients with T2D were included in the study and evaluated before and after LRYGB surgery. No patients were lost to follow-up at any time points. RESULTS: Thirty eight T2D patients with BMI>=27.5 kg/m2 in group 1 (high BMI group) had significant improvements in waist circumference, blood glucose levels, homeostasis model assessment-insulin resistance index, and C-peptide levels after LRYGB (P<.05). Forty T2D patients with BMI<27.5 kg/m2 in group 2 (low BMI group, including 19 T2D patients with BMI<25 kg/m2) had significant improvements in waist circumference and waist-to-hip ratio after LRYGB (P< .05). CONCLUSIONS: LRYGB surgery may be beneficial in T2D patients with BMI<27.5 kg/m2 in China. PMID- 27720197 TI - Long-term and midterm outcomes of laparoscopic sleeve gastrectomy versus Roux-en Y gastric bypass: a systematic review and meta-analysis of comparative studies. AB - OBJECTIVE: This study aimed to compare midterm and long-term weight loss and resolution of co-morbidity with laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG). SUMMARY: LRYGB and LSG are the most common procedures performed in bariatric surgery. However, their weight loss efficacy in the midterm and long-term has not been well compared. METHODS: A meta-analysis was performed by systematically identifying comparative studies conducted until the end of June 2016 that investigated weight loss outcome and resolution of co morbidities (type 2 diabetes mellitus, hypertension, hyperlipidemia, hypertriglyceridemia, and obstructive sleep apnea) with LRYGB and LSG in the midterm (3-5 years) and long term (>=5 years). The primary endpoint was weight loss after LRYGB versus LSG. The secondary endpoint was resolution of co morbidities after these procedures. RESULTS: Fourteen studies comprising 5264 patients were eligible. Follow-up ranged from 36 months to 75.8+/-8.4 months. The pooled result for weight loss outcomes did not show any significant difference in midterm weight loss (standardized mean difference = -0.03; 95% confidence interval (CI), -0.38-.33; P = .88) but a significant difference in the long-term weight loss outcome favoring LRYGB (standardized mean difference = .17; 95% CI, .05-.28; P= .005). The pooled results demonstrated no significant difference for resolution of type 2 diabetes mellitus, hypertension, hyperlipidemia, and hypertriglyceridemia. CONCLUSION: Despite the insignificant difference between LRYGB and LSG in midterm weight loss, LRYGB produced better weight loss in the long-term. There was no significant difference between the 2 procedures for co morbidity resolution. PMID- 27720196 TI - Early improvement in obstructive sleep apnea and increase in orexin levels after bariatric surgery in adolescents and young adults. AB - BACKGROUND: Obstructive sleep apnea (OSA) associated with obesity is known to improve after bariatric surgery, but little is known about early changes in this condition after surgery. OBJECTIVES: To study the clinical course of OSA after bariatric surgery SETTING: Children's hospital in the United States METHODS: Adolescents and young adults with obstructive sleep apnea undergoing vertical sleeve gastrectomy (n = 6) or gastric bypass (n = 1) were enrolled in this prospective study. Participants underwent formal polysomnography before and at 3 and 5 weeks after bariatric surgery. Anthropometric measurements and assay for orexin and leptin were also performed at study visits. Thirty-one adolescents who underwent 2 polysomnography studies that were 4 weeks apart served as control patients. RESULTS: Baseline mean (range) age of participants was 17.8 (15.4-20.7) years, 71% were male, with body mass index of 55.2 (41.3-61.6) kg/m2 and had a median apnea hypopnea index (AHI) of 15.8 (7.1-23.8) events/hour. Differences in least-square means from longitudinal analysis did not show significant differences in AHI in the control group but showed significant postoperative decline in AHI relative to baseline. AHI declined postoperatively from baseline by 9.2 events/hour (95% confidence interval: 3.8 to 14.5) at 3 weeks (P = .002) and 9.1 events/hour (95% confidence interval: 3.8 to 14.5) at 5 weeks (P = .002); there was no significant change from 3 to 5 weeks in AHI. Leptin decreased and orexin levels increased significantly by 3 weeks postoperatively. CONCLUSIONS: These observations suggest that OSA responds early and out of proportion to weight loss after metabolic and or bariatric surgery, thus weight independent factors may at least in part be responsible for early improvement in OSA postoperatively. PMID- 27720199 TI - Connectome Disconnectivity and Cortical Gene Expression in Patients With Schizophrenia. AB - BACKGROUND: Genome-wide association studies have identified several common risk loci for schizophrenia (SCZ). In parallel, neuroimaging studies have shown consistent findings of widespread white matter disconnectivity in patients with SCZ. METHODS: We examined the role of genes in brain connectivity in patients with SCZ by combining transcriptional profiles of 43 SCZ risk genes identified by the recent genome-wide association study of the Schizophrenia Working Group of the Psychiatric Genomics Consortium with data on macroscale connectivity reductions in patients with SCZ. Expression profiles of 43 Psychiatric Genomics Consortium SCZ risk genes were extracted from the Allen Human Brain Atlas, and their average profile across the cortex was correlated to the pattern of cortical disconnectivity as derived from diffusion-weighted magnetic resonance imaging data of patients with SCZ (n = 48) and matched healthy controls (n = 43). RESULTS: The expression profile of SCZ risk genes across cortical regions was significantly correlated with the regional macroscale disconnectivity (r = .588; p = .017). In addition, effects were found to be potentially specific to SCZ, with transcriptional profiles not related to cortical disconnectivity in patients with bipolar I disorder (diffusion-weighted magnetic resonance imaging data; 216 patients, 144 controls). Further examination of correlations across all 20,737 genes present in the Allen Human Brain Atlas showed the set of top 100 strongest correlating genes to display significant enrichment for the disorder, potentially identifying new genes involved in the pathophysiology of SCZ. CONCLUSIONS: Our results suggest that under disease conditions, cortical areas with pronounced expression of risk genes implicated in SCZ form central areas for white matter disconnectivity. PMID- 27720200 TI - Facial Nerve Schwannomas: Review of 80 Cases Over 25 Years at Mayo Clinic. AB - OBJECTIVE: To elucidate the long-term clinical behavior, treatment, and outcomes of sporadic facial nerve schwannoma (FNS) in a large cohort of patients managed in the post-magnetic resonance imaging era. PATIENTS AND METHODS: Retrospective review at a single tertiary health care system (January 1, 1990, through December 31, 2015), evaluating 80 consecutive patients with sporadic FNS. RESULTS: Ninety eight patients with FNS were identified; 10 with incomplete data and 8 with neurofibromatosis type 2 were excluded. The remaining 80 patients (median age, 47 years; 58% women) were analyzed. Forty-three (54%) patients presented with asymmetrical hearing loss, 33 (41%) reported facial paresis, and 21 (26%) reported facial spasm. Seventeen (21%) exhibited radiologic features mimicking vestibular schwannoma, 14 (18%) presented as a parotid mass, and 5 (6%) were discovered incidentally. Factors predictive of facial nerve paresis or spasm before treatment were female sex and tumor involvement of the labyrinthine/geniculate and tympanic facial nerve segments. The median growth rate among growing FNS was 2.0 mm/y. Details regarding clinical outcome according to treatment modality are described. CONCLUSION: In patients with FNS, female sex and involvement of the labyrinthine/geniculate and tympanic segments of the facial nerve predict a higher probability of facial paresis or spasm. When isolated to the posterior fossa or parotid gland, establishing a preoperative diagnosis of FNS is challenging. Treatment should be tailored according to tumor location and size, existing facial nerve function, patient priorities, and age. A management algorithm is presented, prioritizing long-term facial nerve function. PMID- 27720198 TI - The Role of Genes, Stress, and Dopamine in the Development of Schizophrenia. AB - The dopamine hypothesis is the longest standing pathoetiologic theory of schizophrenia. Because it was initially based on indirect evidence and findings in patients with established schizophrenia, it was unclear what role dopamine played in the onset of the disorder. However, recent studies in people at risk of schizophrenia have found elevated striatal dopamine synthesis capacity and increased dopamine release to stress. Furthermore, striatal dopamine changes have been linked to altered cortical function during cognitive tasks, in line with preclinical evidence that a circuit involving cortical projections to the striatum and midbrain may underlie the striatal dopamine changes. Other studies have shown that a number of environmental risk factors for schizophrenia, such as social isolation and childhood trauma, also affect presynaptic dopaminergic function. Advances in preclinical work and genetics have begun to unravel the molecular architecture linking dopamine, psychosis, and psychosocial stress. Included among the many genes associated with risk of schizophrenia are the gene encoding the dopamine D2 receptor and those involved in the upstream regulation of dopaminergic synthesis, through glutamatergic and gamma-aminobutyric acidergic pathways. A number of these pathways are also linked to the stress response. We review these new lines of evidence and present a model of how genes and environmental factors may sensitize the dopamine system so that it is vulnerable to acute stress, leading to progressive dysregulation and the onset of psychosis. Finally, we consider the implications for rational drug development, in particular regionally selective dopaminergic modulation, and the potential of genetic factors to stratify patients. PMID- 27720201 TI - Undersized Mitral Annuloplasty Increases Strain in the Proximal Lateral Left Ventricular Wall. AB - BACKGROUND: Recurrence of mitral regurgitation (MR) after undersized mitral annuloplasty (MA) for ischemic MR is as high as 60%, with the recurrence rate likely due to continued dilation of the left ventricle (LV). To better understand the causes of recurrent MR, we studied the effect of undersized MA on strain in the LV wall. We hypothesize that the acute change in ventricular shape induced by MA will cause increased strain in regions nearest the mitral valve. METHODS: Finite element models were previously reported, based on cardiac magnetic resonance images of 5 sheep with mild to moderate ischemic MR. A 24-mm saddle shaped rigid annuloplasty ring was modeled and used to simulate virtual MA. Longitudinal and myofiber strains were calculated at end-diastole and end systole, with preoperative early diastolic geometry as the reference state. RESULTS: The undersized MA significantly increased longitudinal strain at end diastole in the lateral LV wall. The effect was greatest in the proximal-lateral endocardial surface, where longitudinal strain after MA was approximately triple the preoperative strain (11.17% +/- 2.15% vs 3.45% +/- 0.92%, p = 0.0057). In contrast, postoperative end-diastolic fiber strain decreased in this same region (2.53% +/- 2.14% vs 7.72% +/- 1.79%, p = 0.0060). There were no significant changes in either strain type at end-systole. CONCLUSIONS: Undersized MA increased longitudinal strain in the proximal lateral LV wall at end-diastole. This procedure-related strain at the proximal-lateral LV wall may foster continued LV enlargement and subsequent recurrence of mitral regurgitation. PMID- 27720202 TI - Time-driven activity-based costing of low-dose-rate and high-dose-rate brachytherapy for low-risk prostate cancer. AB - PURPOSE: Cost estimates through traditional hospital accounting systems are often arbitrary and ambiguous. We used time-driven activity-based costing (TDABC) to determine the true cost of low-dose-rate (LDR) and high-dose-rate (HDR) brachytherapy for prostate cancer and demonstrate opportunities for cost containment at an academic referral center. METHODS AND MATERIALS: We implemented TDABC for patients treated with I-125, preplanned LDR and computed tomography based HDR brachytherapy with two implants from initial consultation through 12 month followup. We constructed detailed process maps for provision of both HDR and LDR. Personnel, space, equipment, and material costs of each step were identified and used to derive capacity cost rates, defined as price per minute. Each capacity cost rate was then multiplied by the relevant process time and products were summed to determine total cost of care. RESULTS: The calculated cost to deliver HDR was greater than LDR by $2,668.86 ($9,538 vs. $6,869). The first and second HDR treatment day cost $3,999.67 and $3,955.67, whereas LDR was delivered on one treatment day and cost $3,887.55. The greatest overall cost driver for both LDR and HDR was personnel at 65.6% ($4,506.82) and 67.0% ($6,387.27) of the total cost. After personnel costs, disposable materials contributed the second most for LDR ($1,920.66, 28.0%) and for HDR ($2,295.94, 24.0%). CONCLUSIONS: With TDABC, the true costs to deliver LDR and HDR from the health system perspective were derived. Analysis by physicians and hospital administrators regarding the cost of care afforded redesign opportunities including delivering HDR as one implant. Our work underscores the need to assess clinical outcomes to understand the true difference in value between these modalities. PMID- 27720203 TI - Interstitial brachytherapy as a boost to patients with anal carcinoma and poor response to chemoradiation: Single-institution long-term results. AB - PURPOSE: To analyze the efficacy of a protocol-based brachytherapy (BT) boost after external beam radiation therapy (EBRT) with simultaneous chemotherapy in patients with anal carcinoma. METHODS AND MATERIALS: About 190 patients have been analyzed. Around 143 patients were identified with a good clinical response at the end of EBRT. Another 47 patients received an additional BT boost to the residual tumor at 6 weeks after end of chemoradiation. RESULTS: The 5-year incidence of local recurrence was 24% in patients with BT boost and 19% in patients without BT boost (p = 0.238). The 5-year disease-free survival rate, overall survival rate, and colostomy-free survival rate were 64% and 75% and 76.1% in the BT group and 69% (p = 0.212), 72% (p = 0.924), and 82.7% (p = 0.488) in the non-BT group. We found no differences in late toxicity between the groups. CONCLUSIONS: For patients with anal cancer with not a good response to 50-59 Gy EBRT with simultaneous chemotherapy, the further dose escalation using the BT boost up to a mean of 67.5 Gy seems to improve the clinical outcome to the same level as observed in patients with a good response to ERBT, without an increase in late side effects. PMID- 27720204 TI - Brachytherapy should not be omitted when treating locally advanced neuroendocrine cervical cancer with definitive chemoradiation therapy. AB - PURPOSE: Neuroendocrine cervical cancer is a rare malignancy with a poor prognosis, yet there is a paucity of data to guide treatment decisions when managing patients with this diagnosis. Specifically, there are little data to aid practitioners in deciding if there is added value to brachytherapy given the additional time, cost, discomfort, and toxicity to patients. METHODS AND MATERIALS: We used the National Cancer Data Base to identify women with locally advanced neuroendocrine cervical cancer treated with definitive chemoradiotherapy to determine if the addition of brachytherapy improves outcomes in this disease. We also assessed outcomes based on chemotherapy timing in this cohort. RESULTS: We identified 100 patients with locally advanced nonmetastatic neuroendocrine cervical cancer that were treated with definitive chemoradiotherapy between 2004 and 2012. There was a substantial improvement in overall survival when brachytherapy was administered in addition to external beam radiotherapy. In multivariate analysis, the addition of brachytherapy, compared with external beam radiotherapy alone, was associated with an improved median survival of 48.6 vs. 21.6 months (hazard ratio (HR), 0.475; 95% CI, 0.255-0.883; p = 0.019). We observed no difference in overall survival for patients treated with neoadjuvant chemotherapy compared with the group who received chemotherapy started concurrently with radiation (HR, 0.851; 95% CI, 0.483-1.500; p = 0.578). CONCLUSIONS: Brachytherapy should be considered an essential component of definitive chemoradiotherapy for the treatment of neuroendocrine cervical cancer. Chemotherapy timing, however, does not impact outcome. PMID- 27720205 TI - A novel conformal superficial high-dose-rate brachytherapy device for the treatment of nonmelanoma skin cancer and keloids. AB - PURPOSE: To develop a novel conformal superficial brachytherapy (CSBT) device as a treatment option for the patient-specific radiation therapy of conditions including superficial lesions, postsurgical positive margins, Dupuytren's contractures, keloid scars, and complex anatomic sites (eyelids, nose, ears, etc.). METHODS AND MATERIALS: A preliminary CSBT device prototype was designed, built, and tested using readily available radioactive seeds. Iodine-125 (125I) seeds were independently guided to the treatment surface to conform to the target. Treatment planning was performed via BrachyVision Planning System (BPS) and dose distributions measured with Gafchromic EBT3 film. Percent depth dose curves and profiles for Praseodymium-142 (142Pr), and Strontium-90/Yttrium-90 (90Sr-90Y) were also investigated as potential sources. Results achieved with 90Sr-90Y and electron external beam radiation therapy were compared and Monte Carlo N-Particle eXtended 2.6 simulations of 142Pr seeds were validated. RESULTS: BPS was able to predict clinical dose distributions for a multiple seeds matrix. Calculated and measured doses for the 125I seed matrix were 500 cGy and 473.5 cGy at 5 mm depth, and 171.0 cGy and 201.0 cGy at 10 mm depth, respectively. Results of 90Sr-90Y tests demonstrate a more conformal dose than electron EBRT (1.6 mm compared to 4.3 mm penumbra). Measured 142Pr doses were 500 cGy at surface and 17.4 cGy at 5 mm depth. CONCLUSIONS: The CSBT device provides a highly conformal dose to small surface areas. Commercially available BPS can be used for treatment planning, and Monte Carlo simulation can be used for plans using beta-emitting sources and complex anatomies. Various radionuclides may be used in this device to suit prescription depths and treatment areas. PMID- 27720206 TI - Performance of the Verigene(r) enteric pathogens test, Biofire FilmArrayTM gastrointestinal panel and Luminex xTAG(r) gastrointestinal pathogen panel for detection of common enteric pathogens. AB - BACKGROUND: Multiplex syndromic panels have the capability of identifying causes of diarrheal illness. This study evaluated the performance characteristics of three multiplex molecular assays for the detection of common stool pathogens. METHODS: A total of 152 stool specimens were tested using three platforms: Verigene Enteric Pathogens Test (Verigene), Biofire FilmArray Gastrointestinal Panel (Biofire) and Luminex xTAG(r) Gastrointestinal Pathogen Panel (Luminex). Assays were assessed only for the targets common among all three; namely, Campylobacter, Salmonella, Shigella, Shiga toxin-producing E. coli (STEC), norovirus, and rotavirus. RESULTS: The sensitivities (%) and specificities (%) of the assays were: Campylobacter, Biofire (100,100), Verigene (83.3,99.3), Luminex (91.7,100); Salmonella, Biofire (95.8,100), Verigene (83.3,100), Luminex (79.2,100); Shigella, Biofire (100,100), Verigene (95.4,99.1), Luminex (100,100); STEC, Biofire (100,100), Verigene (91.7,100), Luminex (91.7,100); norovirus, Biofire (94.7,99.3), Verigene (89.0,100), Luminex (89.5,100); and rotavirus, Biofire (100, 98.6), Verigene (71.4,100), Luminex (100,100). CONCLUSIONS: All multiplex panels detected the majority of gastrointestinal pathogens when compared to conventional methods. PMID- 27720207 TI - Identification, antimicrobial resistance and molecular characterization of the human emerging pathogen Streptococcus gallolyticus subsp. pasteurianus. AB - This study aimed to retrospectively identify 22Streptococcus bovis clinical strains based on the new taxonomy, as well as to investigate their antibiotic resistance and clonality. Strains were identified by Phoenix100 system, 16S rRNA sequencing, and two MALDI-TOF MS platforms (Bruker Biotyper, Vitek MS). Antibiotic resistance was determined both phenotypically and genotypically, and clonality was assessed by PFGE. Most of strains (63.6%) were isolated from urine, and diabetes was the most common underlying disease (31.8%). Phoenix100 system revealed all strains belonged to biotype II, and 16S rRNA sequencing identified all strains as S. gallolyticus subsp pasteurianus (SGSP). Although both MALDI-TOF MS systems correctly identified isolates to the species level, only Bruker Biotyper accurately identified to the subspecies level. Erythromycin-resistant strains (31.8%) were also clindamycin-resistant and positive for erm(B). Strains resistant to tetracycline (68.2%) were also resistant to erythromycin. PFGE showed high genetic variability identifying 17 different pulsotypes, most of which single.

Clinical characteristics and outcomes of M. chimaera lung disease were comparable to M. intracellulare lung disease. PMID- 27720209 TI - Decreasing prevalence of heterogeneous vancomycin-intermediate Staphylococcus aureus among blood isolates in Korean hospitals. AB - We investigated the prevalence of heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) among methicillin-resistant S. aureus (MRSA) blood isolates collected from Korean hospitals. The hVISA prevalence in Korean hospitals has decreased during the past decade and the most significant decrease of hVISA prevalence was observed among the ST5 MRSA. PMID- 27720211 TI - History of His bundle pacing. AB - Chronic right ventricular (RV) pacing has been shown over the years to exert detrimental physiological changes including increased risk for heart failure and atrial fibrillation. His bundle pacing offers the promise of physiological activation of the ventricular tissue, with the potential for reducing the detrimental effects of RV pacing. We describe His bundle pacing in a historical context and briefly highlight several clinical trials that have helped shape the landscape of permanent His bundle pacing. PMID- 27720210 TI - Measuring fear of falling among high-risk, urban, community-dwelling older adults. AB - Fear of falling (FOF) creates a psychological barrier to performing activities for many older adults. The negative impact of fear of falling increases risk of curtailment of activities, future falls, and injury. The specific aim for this study was to investigate the relationship between two fear of falling measures used in clinical research, the FOF Likert scale and Falls Self Efficacy Scale International (FES-I). The study included a convenience sample of 107 high-risk, community-dwelling, mostly Black (94%) members from one Program for All-Inclusive Care for the Elderly program. The FOF scale is one-item asking to rate overall concern about falling, while the FES-I is 16-items rating concern about falling during physical and social activities. One-way ANOVA and Kruskal-Wallis were highly significant (F-value = 22.25, R-squared = 0.39, p < 0.0001). The Graded Response Model statistics demonstrated one underlying latent factor, fear of falling. This study supports the use of both tools for thorough FOF measurement. PMID- 27720212 TI - Introduction: 50 years of evolution of contraceptive medicine. AB - The science of contraceptive medicine and reproductive medicine are similar. At present contraceptive medicine has moved beyond understanding the mechanism of action of steroid hormones with the introduction of many safe and effective methods. Long-acting reversible contraceptives are increasing in acceptance and providing very high efficacy. The science has pivoted toward optimization of family planning in selected high-risk populations, such as those with a high-risk of thrombosis, as well as addressing the challenge of obesity. The pipeline for male and female related methods will continue to advance the science and public health impact. PMID- 27720214 TI - [Ultrasound-guided facet block]. PMID- 27720215 TI - From Precaution to Peril: Public Relations Across Forty Years of Genetic Engineering. AB - The Asilomar conference on genetic engineering in 1975 has long been pointed to by scientists as a model for internal regulation and public engagement. In 2015, the organizers of the International Summit on Human Gene Editing in Washington, DC looked to Asilomar as they sought to address the implications of the new CRISPR gene editing technique. Like at Asilomar, the conveners chose to limit the discussion to a narrow set of potential CRISPR applications, involving inheritable human genome editing. The adoption by scientists in 2015 of an Asilomar-like script for discussing genetic engineering offers historians the opportunity to analyze the adjustments that have been made since 1975, and to identify the blind spots that remain in public engagement. Scientists did take important lessons from the fallout of their limited engagement with public concerns at Asilomar. Nonetheless, the scientific community has continued to overlook some of the longstanding public concerns about genetic engineering, in particular the broad and often covert genetic modification of food products. PMID- 27720213 TI - microRNA Therapeutics in Cancer - An Emerging Concept. AB - MicroRNAs (miRNAs) are an evolutionarily conserved class of small, regulatory non coding RNAs that negatively regulate protein coding gene and other non-coding transcripts expression. miRNAs have been established as master regulators of cellular processes, and they play a vital role in tumor initiation, progression and metastasis. Further, widespread deregulation of microRNAs have been reported in several cancers, with several microRNAs playing oncogenic and tumor suppressive roles. Based on these, miRNAs have emerged as promising therapeutic tools for cancer management. In this review, we have focused on the roles of miRNAs in tumorigenesis, the miRNA-based therapeutic strategies currently being evaluated for use in cancer, and the advantages and current challenges to their use in the clinic. PMID- 27720216 TI - Impact of a harbour construction on the benthic community of two shallow marine caves. AB - Marine caves are unique and vulnerable habitats, threatened by multiple global and local disturbances. Whilst the effects of climate change on marine caves have already been investigated, no information exists about the effects of local human impacts, such as coastal development, on these habitats. This study investigated the impact of the construction of a touristic harbour on two shallow underwater marine caves in the Ligurian Sea (NW Mediterranean). As a standard methodology for monitoring marine caves does not exist yet, changes over time on the benthic community were assessed adopting two different non-taxonomic descriptors: trophic guilds and growth forms. Harbour construction caused an increase of sediment load within the caves, with a consequent decline of filter feeder organisms. Abundance of small organisms, such as encrusting and flattened sponges, was greatly reduced in comparison to organisms with larger and erect growth forms, such as domed mounds and pedunculated sponges. Our study indicated that growth forms and trophic guilds are effective descriptors for evaluating changes over time in marine caves, and could be easily standardised and applied in monitoring plans. In addition, as the harbour construction impacted differently according to the cave topography, the use of a systematic sampling in different zones of an underwater cave is recommended. PMID- 27720218 TI - Management and environmental risk study of the physicochemical parameters of ballast water. AB - Shipping is a vital industry for the global economy. Stability of ships, provided by ballast water, is a crucial factor for cargo loading and unloading processes. Ballast water treatment has practical significance in terms of environmental issues, ecosystem, and human health, because ships discharge this water into the environment before loading their cargos. This study reviews the common methods for ballast water management - exchange, heating, filtration, ultrasonic treatment, ultraviolet irradiation, chemicals, and gas supersaturation - to select the best one. This study compares water temperature, salinity, dissolved oxygen, polycyclic aromatic hydrocarbons (PAHs), and heavy metals (Co, Cr, Ni, Pb) for ballast tanks of selected ships with the recipient port environment in the Persian Gulf as a case study. The exchange of ballast water in the ocean and/or its treatment on board to prevent inadvertent effects on the environment's physicochemical conditions is related to vessel characteristics, legislation, and the environmental condition. Ecological risk study showed that the salt content in ballast water is close to that of seawater, but the values of Cr (2.1mg/l) and Ni (0.029mg/l) in ballast water are higher than those in seawater (1 and 0.004mg/l, respectively). PMID- 27720219 TI - Mental health indicators fifty years later: A population-based study of men with histories of child sexual abuse. AB - Childhood sexual abuse (CSA) is a widely acknowledged trauma that affects a substantial number of boys/men and has the potential to undermine mental health across the lifespan. Despite the topic's importance, few studies have examined the long-term effects of CSA on mental health in middle and late life for men. Most empirical studies on the effects of CSA have been conducted with women, non probability samples, and samples of young or emerging adults with inadequate control variables. Based on complex trauma theory, the current study investigated: a) the effect of CSA on mental health outcomes (depressive symptoms, somatic symptom severity, hostility) in late life for men, and b) the moderating effects of childhood adversities and masculine norms in the relationship between CSA and the three mental health outcomes. Using a population based sample from the 2004-2005 Wisconsin Longitudinal Study, multivariate analyses found that CSA was positively related to both depressive and somatic symptoms and increased the likelihood of hostility for men who reported a history of CSA. Both childhood adversities and masculine norms were positively related to the three outcomes for the entire sample. Among CSA survivors, childhood adversities exerted a moderating effect in terms of depressive symptoms. Mental health practitioners should include CSA and childhood adversities in assessment and treatment with men. To more fully understand the effects of CSA, future studies are needed that use longitudinal designs, compare male and female survivors, and examine protective mechanisms such as social support.

PMID- 27720221 TI - Concurrent gemcitabine and radiotherapy for the treatment of muscle-invasive bladder cancer: A pooled individual data analysis of eight phase I-II trials. AB - PURPOSE: Although radical cystectomy is still considered the standard of care for most localized muscle-invasive bladder cancer (MIBC) patients, bladder-sparing strategies with chemoradiotherapy have demonstrated comparable local control and survival rates when adjusting for tumor stage. We present a pooled analysis of individual patient data out of published trials with gemcitabine-based chemoradiotherapy for MIBC. METHODS AND MATERIALS: Individual patient data were collected from Institutions that enrolled patients into trials that evaluated gemcitabine-based chemoradiotherapy for MIBC. RESULTS: We identified eight studies published on gemcitabine-based radiochemotherapy and 190 patients were included in this analysis. A complete response (CR) was observed in 166 patients (93%). After a median follow up of 44.5months, 36 patients (18.9%) presented a bladder recurrence and 14 subsequently underwent cystectomy. The 5-year overall survival (OS), disease-specific survival (DSS), and cystectomy-free survival (CFS) rates were 59%, 80.9%, and 93.3%, respectively. The achievement of CR after chemoradiotherapy was the main prognostic variable which was associated with improved OS, DSS, and CFS. The treatment was well tolerated. CONCLUSION: This pooled analysis strengthens the evidence that chemoradiotherapy regimens with concurrent gemcitabine are feasible and well tolerated. Prospective randomized controlled trials are on-going to definitively assess the efficacy of gemcitabine based chemoradiotherapy for MIBC. PMID- 27720223 TI - Bariatric surgery and intellectual disability: Furthering evidence-based practice. AB - BACKGROUND: Rates of morbid obesity are higher for individuals with intellectual disability (ID). Individuals with ID may find nutritional guidelines difficult to follow and many face personal and environmental barriers for physical activity. Bariatric surgery may reduce obesity related health comorbidities while promoting sustained weight loss in diverse populations. Yet no study has reviewed the feasibility of conducting bariatric surgery on individuals with ID. OBJECTIVES: To conduct a scoping review of literature on bariatric procedures performed on individuals with ID. METHODS: Authors searched electronic database via PubMED, Science Direct, Wiley and Medline (1975-2014). Extracted articles were evaluated independently following scoping reviews guidelines. RESULTS: Reviewers included sixteen studies. Nine surgical interventions were reported on 49 patients with ID. Studies followed either case report or case series design. The most common procedure patients received was biliopancreatic diversion (n = 24) followed by Roux-en-Y Gastric Bypass (n = 12). Degree of weight loss was the primary outcome in each study. Excess weight loss (%EWL) ranged from 12% to 86%. Further benefits included improved quality of life, decreased psychological tension within family and resolution of sleep apnea, hypertension, respiratory distress and type II diabetes. Six studies included a post-operative follow-up period below two years. CONCLUSIONS: Bariatric surgery may be a viable option to treat obesity in individuals with ID but there is no consensus which procedure is preferred and which associated interventions should be in place to warrant long lasting results. Further research featuring randomized control trials may be beneficial. PMID- 27720222 TI - Intestinal barrier dysfunction in human necrotizing enterocolitis. AB - BACKGROUND: Intestinal barrier dysfunction has been implicated in necrotizing enterocolitis (NEC), but has not been directly measured in human NEC. METHODS: Small intestines removed during surgery were immediately mounted in an Ussing chamber. mRNA expression of tight junction (TJ) proteins was measured with RT PCR. RESULTS: Fifteen infants were included, 5 with NEC and 10 with other diagnoses. Average transepithelial resistance (TER) was 11.61+/-1.65Omega/cm2 in NEC specimens, 23.36+/-1.48Omega/cm2 at resection margin, and 46.48+/ 5.65Omega/cm2 in controls. Average flux of permeability marker mannitol was 0.23+/-0.06MUMol/cm2 per h in NEC, 0.04+/-0.01 MUMol/cm2 per h at resection margin, and 0.017+/-0.004 MUMol/cm2 per h in control tissue (p<0.05). RT-PCR analysis showed marked decrease in mRNA expression of a TJ protein occludin in NEC affected tissue (p<0.03 vs. control). Additionally, mRNA expression of myosin light chain kinase (MLCK), an important regulator of TJ permeability, was increased in NEC specimens. CONCLUSION: These studies show for the first time that NEC intestinal tissue have increased intestinal permeability, even at grossly healthy-appearing resection areas. The increase in intestinal permeability in NEC appeared to be related in part to a decrease in occludin and an increase in MLCK expression. LEVEL OF EVIDENCE: Level 2.

PMID- 27720224 TI - Genome organization of the vg1 and nodal3 gene clusters in the allotetraploid frog Xenopus laevis. AB - Extracellular factors belonging to the TGF-beta family play pivotal roles in the formation and patterning of germ layers during early Xenopus embryogenesis. Here, we show that the vg1 and nodal3 genes of Xenopus laevis are present in gene clusters on chromosomes XLA1L and XLA3L, respectively, and that both gene clusters have been completely lost from the syntenic S chromosome regions. The presence of gene clusters and chromosome-specific gene loss were confirmed by cDNA FISH analyses. Sequence and expression analyses revealed that paralogous genes in the vg1 and nodal3 clusters on the L chromosomes were also altered compared to their Xenopus tropicalis orthologs. X. laevis vg1 and nodal3 paralogs have potentially become pseudogenes or sub-functionalized genes and are expressed at different levels. As X. tropicalis has a single vg1 gene on chromosome XTR1, the ancestral vg1 gene in X. laevis appears to have been expanded on XLA1L. Of note, two reported vg1 genes, vg1(S20) and vg1(P20), reside in the cluster on XLA1L. The nodal3 gene cluster is also present on X. tropicalis chromosome XTR3, but phylogenetic analysis indicates that nodal3 genes in X. laevis and X. tropicalis were independently expanded and/or evolved in concert within each cluster by gene conversion. These findings provide insights into the function and molecular evolution of TGF-beta family genes in response to allotetraploidization. PMID- 27720226 TI - Circadian-Time Sickness: Time-of-Day Cue-Conflicts Directly Affect Health. AB - A daily rhythm that is not in synchrony with the environmental light-dark cycle (as in jetlag and shift work) is known to affect mood and health through an as yet unresolved neural mechanism. Here, we combine Bayesian probabilistic 'cue conflict' theory with known physiology of the biological clock of the brain, entailing the insight that, for a functional pacemaker, it is sufficient to have two interacting units (reflecting environmental and internal time-of-day cues), without the need for an extra homuncular directing unit. Unnatural light-dark cycles cause a time-of-day cue-conflict that is reflected by a desynchronization between the ventral (environmental) and dorsal (internal) pacemaking signals of the pacemaker. We argue that this desynchronization, in-and-of-itself, produces health issues that we designate as 'circadian-time sickness', analogous to 'motion sickness'. PMID- 27720229 TI - Experimental method to characterize the strain dependent permeability of tissue engineering scaffolds. AB - Permeability is an overarching mechanical parameter encompassing the effects of porosity, pore size, and interconnectivity of porous structures. This parameter directly influences transport of soluble particles and indirectly regulates fluid pressure and velocity in tissue engineering scaffolds. The permeability also contributes to the viscoelastic behavior of visco-porous material under loading through frictional drag mechanism. We propose a straightforward experimental method for permeability characterization of tissue engineering scaffolds. In the developed set-up a step-wise spacer was designed to facilitate measurement of the permeability under different compressive strains while maintaining similar experimental conditions during the successive measurements. As illustration of the method, we measured the permeability of scaffolds presenting different average pore sizes and subjected to different compression values. Results showed an exponential relationship between the permeability and the average pore size of the scaffolds. Furthermore, the trend of the permeability decrease with compressive strains was depending on pore sizes of the scaffolds. The permeability also appeared to play a role in relaxation behavior of the scaffolds. PMID- 27720227 TI - Both intrinsic and extrinsic apoptotic pathways are involved in Toll-like receptor 4 (TLR4)-induced cell death in monocytic THP-1 cells. AB - Our previous study showed that TLR3 induces apoptosis via both death receptors and mitochondial in human endothelial cells. We report here that the activation of TLR4 induced dose- and time-dependent cell death in moncytic THP-1 cells. LPS treatment of THP-1 cells induced the activation of both caspase 8 and 9, suggesting the involvement of intrinsic and extrinsic apoptosis pathways. TNFalpha was induced by TLR4 activation at both mRNA and protein levels, but its neutralization did not down-regulated TLR4-induced cell death. TLR4 activation also induced the up-regulation of TRAIL and its receptors DR4 and DR5, and the neutralization of TRAIL ameliorated TLR4 induced apoptosis, suggesting the involvement of TRAIL and its receptors DR4 and DR5 in LPS-induced cell death. Meanwhile, LPS treatment down-regulated the expression of FLICE inhibitory protein (FLIP), a suppressor of death receptor-induced cell death. In addition, TLR4 activation down-regulated the anti-apoptotic protein bcl-2, and up-regulated the pro-apoptotic proteins Noxa and Puma, suggesting that mitochondrial apoptotic pathway was also involved in LPS-induced cell death. Furthermore, we found that TAP63alpha might confer to the activation of intrinsic and extrinsic apoptotic pathways. The treatment of THP-1 cells with LPS induced the translocation of TAP63alpha from cytoplasm to nucleus. Taken together, our study suggested that both death receptors and mitochondial were involved in TLR4-induced cell death, and TAP63alpha may be a target for the prevention of LPS-induced cell death. PMID- 27720228 TI - Postoperative time dependent tibiofemoral articular cartilage contact kinematics during step-up after ACL reconstruction. AB - This study was to investigate the in vivo tibiofemoral cartilage contact locations before and after anterior cruciate ligament (ACL) reconstruction at 6 and 36 months. Ten patients with unilateral ACL injury were included. A step-up motion was analyzed using a combined magnetic resonance modeling and dual fluoroscopic imaging techniques. The preoperative (i.e. ACL deficient and healthy contralateral) and postoperative cartilage contact locations at 6 and 36 months were analyzed. Similar patterns of the cartilage contact locations during the step-up motion were found for the preoperative and postoperative knee states as compared to the preoperative healthy contralateral side. At the end of step-up motion, the medial contact locations at postoperative 36 months were more anterior when compared to the preoperative healthy contralateral (p=0.02) and 6 months postoperative knee states (p=0.01). The changes of the cartilage contact locations at 36 months after ACL reconstruction compared to the healthy contralateral side were strongly correlated with the changes at 6 months postoperatively. This study showed that the tibiofemoral cartilage contact locations of the knee changes with time after ACL reconstruction, implying an ongoing recovery process within the 36 months after the surgery. There could be an association between the short-term (6 months) and longer-term (36 months) contact kinematics after ACL reconstruction. Future studies need to investigate the intrinsic relationship between knee kinematics at different times after ACL reconstruction. PMID- 27720230 TI - Neuropeptide Y accelerates post-fracture bone healing by promoting osteogenesis of mesenchymal stem cells. AB - Fracture repair is a complex yet well orchestrated regenerative process involving numerous signaling and cell types including osteoblasts. Here we showed that NPY, a neurotransmitter with regulatory functions in bone homeostasis, may contribute to the post-fracture bone healing in patients with traumatic brain injury fracture combined injuries. Our results suggested NPY levels were increased in patients with the combined injuries, accomplished by arising of bone healing markers, such as ALP, OC, PICP and ICTP, than in those with simple fractures, and NPY have direct actions on MSCs to promote their osteogenic differentiation. Our results provided clinical evidences for NPY participating in the bone healing process in a nonhypothalamic manner, most probably by directly promoting osteogenesis of mesenchymal stem cells. PMID- 27720231 TI - The association between reproductive and hormonal factors and ovarian cancer by estrogen-alpha and progesterone receptor status. AB - OBJECTIVE: We assessed the association between reproductive and hormonal factors and ovarian cancer incidence characterized by estrogen receptor-alpha (ERalpha) and progesterone receptor (PR) status. METHODS: Tissue microarrays were used to assess ERalpha and PR expression among 197 Nurses' Health Study (NHS), 42 NHSII and 76 New England Case-Control Study (NECC) ovarian cancer cases. NHS/NHSII cases were matched to up to 4 controls (n=954) on diagnosis date and birth year. NECC controls (n=725) were frequency matched on age. Cases were considered receptor positive if >=1% of tumor cells stained positive. Associations by ERalpha and PR status were assessed using polytomous logistic regression. p-Value for heterogeneity was calculated using a likelihood ratio test. RESULTS: 45% of ovarian tumors were PR(+), 78% were ERalpha(+) and 45% were ERalpha(+)/PR(+), while 22% were ERalpha(-)/PR(-). Postmenopausal status was associated with an increased risk of PR(-) tumors (OR: 2.07; 95%CI: 1.15-3.75; p-heterogeneity=0.01) and age at natural menopause was inversely associated with PR(-) tumors (OR, per 5years: 0.77; 95%CI: 0.61-0.96; p-het=0.01). Increasing duration of postmenopause was differentially associated by PR status (p-het=0.0009). Number of children and tubal ligation were more strongly associated with ERalpha(-) versus ERalpha(+) tumors (p-het=0.002 and 0.05, respectively). No differential associations were observed for oral contraceptive or hormone therapy use. CONCLUSIONS: Postmenopausal women have an increased risk of developing PR(-) ovarian tumors compared to premenopausal women. The associations observed for ovarian cancer differ from those seen for breast cancer suggesting that the biology for tumor development through ERalpha and PR pathways may differ. PMID- 27720233 TI - Are Antibiotics Necessary for Dental Pain Without Overt Infection? PMID- 27720232 TI - Distance from a Comprehensive Cancer Center: A proxy for poor cervical cancer outcomes? AB - OBJECTIVE: To evaluate the potential relationship between outcomes in cervical cancer patients based on distance from our Comprehensive Cancer Center (CCC). METHODS: A retrospective cohort study of cervical cancer patients was performed. Abstracted data included: demographics, clinicopathologic variables, treatment, and survival. Analyses both by quartiles and distance <100 and >=100miles from our institution were performed. Data were analyzed using SAS version 9.2. RESULTS: 390 patients living a median distance of 58.1miles (range 1.2-571miles) from our CCC were identified. Patients were generally white (n=249), non-smokers (n=226), with Stage IB disease (n=222), squamous histology (n=295) and underwent primary surgical therapy (n=229). Patients were divided into both quartiles as well as two strata: <100 and >=100miles for comparison. Progression-free survival (PFS) and overall survival (OS) favored patients living closer to our center with a lower median OS for patients living >=100miles (65.4vs. 99.4months; p=0.040). Cox proportional hazard modeling noted that advanced stage was predictive of inferior PFS and OS, while other clinical covariates including age, BMI, race, smoking status and histology had a variable impact on outcomes and distance >100miles was associated with a higher risk of death (hazard ratio [HR]=1.68, 95% confidence interval [CI] 1.11-2.54). CONCLUSION: Overall survival for patients living >100miles from our CCC was worse when compared to patients in closer proximity. Outreach efforts and utilization of navigators may help decrease the impact of geographic and racial disparities on outcomes. PMID- 27720235 TI - Perioperative Risk in Patients With Epilepsy Undergoing Total Joint Arthroplasty. AB - BACKGROUND: Epilepsies is a spectrum of brain disorders ranging from severe, life threatening, and disabling to more benign, but little is known about its impact in the perioperative arthroplasty setting. We sought to determine whether epileptic patients undergoing elective total joint arthroplasty (TJA) would be at increased risk for in-hospital complications and death, prolonged stay, and nonroutine discharge. METHODS: Using discharge records from the Nationwide Inpatient Sample (2002-2011), we identified 6,054,344 patients undergoing elective primary TJA, of whom 31,865 (0.5%) were identified as having epilepsy. Comparisons of perioperative outcomes were performed by multivariable logistic regression modeling. RESULTS: Patients with epilepsy were associated with increased in-hospital mortality (odds ratio [OR] 2.03, 95% confidence interval [CI] 1.57-2.62) and morbidity, including (in decreasing order of magnitude of effect estimate): mechanical ventilation (OR 1.74, 95% CI 1.56-1.94), induced mental disorder (OR 1.70, 95% CI 1.56-1.85), stroke (OR 1.63, 95% CI 1.23-2.15), pneumonia (OR 1.34, 95% CI 1.21-1.49), and ileus or gastrointestinal events (OR 1.26, 95% CI 1.12-1.42). Epilepsy was associated with higher risk for blood transfusion (OR 1.30, 95% CI 1.27-1.33), prolonged hospital stay (OR 1.14, 95% CI 1.11-1.17), and nonroutine discharge (OR 1.54, 95% CI 1.50-1.58). We found no association with inpatient thromboembolic events, acute renal failure, and myocardial infarction. CONCLUSION: Patients with epilepsy are at increased risk for early postoperative complications (especially mechanical ventilation, induced mental disorder, and stroke) and resource utilization after elective joint arthroplasty. Greater awareness of epilepsy and its health consequences may contribute to improvements in the perioperative management of TJA patients. PMID- 27720234 TI - Metabolic control of immune tolerance in health and autoimmunity. AB - The filed that links immunity and metabolism is rapidly expanding. The adipose tissue, by secreting a series of immune regulators called adipokines, represents the common mediator linking metabolic processes and immune system functions. The dysregulation of adipokine secretion, occurring in obese individuals or in conditions of malnutrition or dietary restriction, affects the activity of immune cells resulting in inflammatory autoimmune responses or increased susceptibility to infectious diseases. Alterations of cell metabolism that characterize several autoimmune diseases strongly support the idea that the immune tolerance is also regulated by metabolic pathways. The comprehension of the molecular mechanisms underlying these alterations may lead to the development of novel therapeutic strategies to control immune cell differentiation and function in conditions of autoimmunity. PMID- 27720236 TI - Evaluation of foot position and orientation as manipulated variables to control external knee adduction moments in leg extension training. AB - BACKGROUND AND OBJECTIVE: Effective leg extension training at a leg press requires high forces, which need to be controlled to avoid training-induced damage. In order to avoid high external knee adduction moments, which are one reason for unphysiological loadings on knee joint structures, both training movements and the whole reaction force vector need to be observed. In this study, the applicability of lateral and medial changes in foot orientation and position as possible manipulated variables to control external knee adduction moments is investigated. As secondary parameters both the medio-lateral position of the center of pressure and the frontal-plane orientation of the reaction force vector are analyzed. METHODS: Knee adduction moments are estimated using a dynamic model of the musculoskeletal system together with the measured reaction force vector and the motion of the subject by solving the inverse kinematic and dynamic problem. Six different foot conditions with varying positions and orientations of the foot in a static leg press are evaluated and compared to a neutral foot position. RESULTS: Both lateral and medial wedges under the foot and medial and lateral shifts of the foot can influence external knee adduction moments in the presented study with six healthy subjects. Different effects are observed with the varying conditions: the pose of the leg is changed and the direction and center of pressure of the reaction force vector is influenced. Each effect results in a different direction or center of pressure of the reaction force vector. CONCLUSIONS: The results allow the conclusion that foot position and orientation can be used as manipulated variables in a control loop to actively control knee adduction moments in leg extension training. PMID- 27720237 TI - Novel volatiles of skin-borne bacteria inhibit the growth of Gram-positive bacteria and affect quorum-sensing controlled phenotypes of Gram-negative bacteria. AB - The skin microbiota is import for body protection. Here we present the first comprehensive analysis of the volatile organic compound (VOC) profiles of typical skin-resident corynebacterial and staphylococcal species. The VOC profile of Staphylococcus schleiferi DSMZ 4807 was of particular interest as it is dominated by two compounds, 3-(phenylamino)butan-2-one and 3-(phenylimino)butan-2-one (schleiferon A and B, respectively). Neither of these has previously been reported from natural sources. Schleiferon A and B inhibited the growth of various Gram-positive species and affected two quorum-sensing-dependent phenotypes - prodigiosin accumulation and bioluminescence - of Gram-negative bacteria. Both compounds were found to inhibit the expression of prodigiosin biosynthetic genes and stimulate the expression of prodigiosin regulatory genes pigP and pigS. This study demonstrates that the volatile schleiferons A and B emitted by the skin bacterium S. schleiferi modulate differentially and specifically its interactions with members of diverse bacterial communities. A network of VOC-mediated interspecies interactions and communications must be considered in the establishment of the (skin) microbiome and both compounds are interesting candidates for further investigations to better understand how VOCs emitted by skin bacteria influence and modulate the local microbiota and determine whether they are relevant to antibiotic and anti-virulence therapies. PMID- 27720238 TI - [Cross sectional study of comorbidities and concomitant medications in a cohort of human immunodeficiency virus-infected patients]. AB - AIM: To assess the prevalence of comorbidities, concomitant therapies and adverse effects associated with the medication in a cohort of patients with HIV infection. DESIGN: Multicentre cross-sectional study. SETTINGS: Infectious Diseases or Internal Medicine outpatient Clinics of 3 hospitals in the Basque Country. PARTICIPANTS: During a 3 month period, patients with the following inclusion criteria were randomly selected: HIV infection, age>18years, antiretroviral treatment (ART) for at least 6months, and no changes in ART in the previous 4weeks. A total of 224 patients (of the 225 expected) were included. MEASUREMENTS: Data were collected using a form, and include, epidemiological and anthropometric data, data related to HIV infection, comorbidities, current therapies, and adverse effects. RESULTS: Of the 224 patients, 95.5% had at least one comorbidity, the most common being HCV infection (51.3%), dyslipidaemia (37.9%), diabetes mellitus or impaired fasting glucose (21.9%), and hypertension (21.9%). A total of 155 patients (69.2%) were taking concomitant medication: anxiolytics (21.4%), antihypertensives (19.6%), proton pump inhibitors (17.9%), statins (17%), and antidepressants (16.5%). Adverse effects (AE) were observed in 62.9% of subjects, the most common being, changes in body fat distribution (32.6%) and gastrointestinal (24.1%). CONCLUSIONS: Patients with HIV infection are getting older, with more comorbidities, with very frequent use of concomitant treatments, and high number of adverse effects. This requires a multidisciplinary approach and a coordinated effort within the Primary Care setting.

AB - OBJECTIVE: To evaluate the association between handgrip strength and ideal cardiovascular health (CVH) in Colombian children and adolescents. STUDY DESIGN: During the 2014-2015 school years, we examined a cross-sectional component of the FUPRECOL (Association for Muscular Strength with Early Manifestation of Cardiovascular Disease Risk Factors among Colombian Children and Adolescents) study. Participants included 1199 (n = 627 boys) youths from Bogota (Colombia). Handgrip strength was measured with a standard adjustable hand held dynamometer and expressed relative to body mass (handgrip/body mass) and as absolute values in kilograms. Ideal CVH, as defined by the American Heart Association, was determined as meeting ideal levels of the following components: 4 behaviors (smoking status, body mass index, cardiorespiratory fitness, and diet) and 3 factors (total cholesterol, blood pressure, and glucose). RESULTS: Higher levels of handgrip strength (both absolute and relative values) were associated with a higher frequency of ideal CVH metrics in both sexes (P for trend <= .001). Also, higher levels of handgrip strength were associated with a greater number of ideal health behaviors (P for trend < .001 in both boys and girls), and with a higher number of ideal health factors in boys (P for trend < .001). Finally, levels of handgrip strength were similar between ideal versus nonideal glucose or total cholesterol groups in girls. CONCLUSIONS: Handgrip strength was strongly associated with ideal CVH in Colombian children and adolescents, and thus supports the relevance of early targeted interventions to promote strength adaptation and preservation as part of primordial prevention. PMID- 27720243 TI - Quality of Life in Type 1 Diabetes and Celiac Disease: Role of the Gluten-Free Diet. AB - OBJECTIVE: To evaluate quality of life (QoL) and glycemic control in youth with type 1 diabetes (T1D) and celiac disease vs T1D only. We hypothesized that QoL scores would be lower in youth with T1D and celiac disease and those nonadherent to the gluten-free diet (GFD). STUDY DESIGN: This case control study included 35 youth with T1D and 35 with T1D and celiac disease matched for age, sex, diabetes duration, and hemoglobin A1c level. QoL was assessed in participants and parents using the Pediatric Quality of Life Inventory Generic Core Scale, Pediatric Quality of Life Inventory Diabetes Module. and the General Well-Being Scale; youth with T1D and celiac disease also completed the celiac disease specific DUX questionnaire and parents completed the Pediatric Quality of Life Inventory Family Impact Scale. Questionnaires were scored from 0 to 100; higher scores indicate better QoL or well-being. Scores were compared between T1D vs T1D with celiac disease, with subgroup analysis by GFD adherence vs nonadherence and therapy (continuous subcutaneous insulin infusion vs multiple daily injections). RESULTS: Youth with T1D and celiac disease reported similar generic and diabetes specific QoL to T1D only. GFD nonadherent vs adherent youth reported lower diabetes-specific QoL (mean score 58 vs 75, P = .003) and lower general well being (57 vs 76, P = .02), as did their parents (50 vs 72, P = .006), and hemoglobin A1c was higher (9.6% vs 8.0%, P = .02). Youth with T1D and celiac disease using continuous subcutaneous insulin infusion vs multiple daily injections had similar generic and diabetes-specific QoL and A1C (8.6 vs 8.2%, P = .44), but were less happy having to follow a lifelong diet (59 vs 29, P = .007). CONCLUSIONS: Youth with T1D and celiac disease who do not adhere to the GFD have lower QoL and worse glycemic control. Novel strategies are required to understand and improve adherence in those with both conditions. PMID- 27720244 TI - Child- and Parent-Reported Health: The Rashomon Effect of Multiple Realities.

PMID- 27720247 TI - Time-lapse embryo imaging and morphokinetic profiling: Towards a general characterisation of embryogenesis. AB - In vitro fertilisation is an effective method of assisted reproductive technology in both humans and certain non-human animal species. In most species, specifically, in humans and livestock, high in vitro fertilisation success rates are achieved via the transfer of embryos with the highest implantation and subsequent developmental potential. In order to reduce the risk of multiple gestation, which could be a result of the transfer of several embryos per cycle, restrictive transfer policies and methods to improve single embryo selection have been implemented. A non-invasive alternative to standard microscopic observation of post-fertilisation embryo morphology and development is time-lapse technology; this enables continuous, uninterrupted observation of embryo development from fertilisation to transfer. Today, there are several time-lapse devices that are commercially available for clinical use, and methods in which time-lapse could be used to improve embryology are continually being assessed. Here we review the use of time-lapse technology in the characterisation of embryogenesis and its role in embryo selection. Furthermore, the prospect of using this technology to identify aneuploidy in human embryos, as well as the use of time-lapse to improve embryological procedures in agriculturally important species such as the pig and cow are discussed. PMID- 27720246 TI - Extra-central nervous system target for assessment and treatment in refractory anti-N-methyl-d-aspartate receptor encephalitis. AB - Anti-N-methyl-d-aspartate-type glutamate receptor autoimmune encephalitis can arise in the setting of ovarian teratoma and often responds to resection. When it occurs in the absence of tumor, failure to respond to treatment may be more likely, and affected patients often require intensive care. To further understand the mechanisms and potential management, we present findings from an autopsy conducted on a young woman who died of refractory autoimmune encephalitis of this type. Rituximab was administered 70 days before death, and both 37 and 14 days before death, CD19+ lymphocytes were only 0.1% of blood cells. Ten sessions of plasmapheresis were performed after rituximab treatment. Nonetheless, the autoantibodies were present in serum 4 days before death, demonstrating ongoing antibody production. The hippocampus and medial temporal lobe demonstrated inflammation with T cell and prominent microglial involvement, but no plasma cells or plasmablasts were found there, or anywhere in the brain, despite an extensive search. Examination of lymph node tissue identified many plasma cells along sinusoids. These findings demonstrate that the antibody-producing cells are long-lived and can reside in lymphoid tissue. Awareness of continuing antibody production, the extra-central nervous system site, the indication for cytotoxic therapy, and the potential for biopsy assessment may lead to more effective treatment. PMID- 27720250 TI - Differentiating the sources of fine sediment, organic matter and nitrogen in a subtropical Australian catchment. AB - Understanding the sources of sediment, organic matter and nitrogen (N) transferred from terrestrial to aquatic environments is important for managing the deleterious off-site impacts of soil erosion. In particular, investigating the sources of organic matter associated with fine sediment may also provide insight into carbon (C) and N budgets. Accordingly, the main sources of fine sediment, organic matter (indicated by total organic carbon), and N are determined for three nested catchments (2.5km2, 75km2, and 3076km2) in subtropical Australia. Source samples included subsoil and surface soil, along with C3 and C4 vegetation. All samples were analysed for stable isotopes (delta13C, delta15N) and elemental composition (TOC, TN). A stable isotope mixing model (SIAR) was used to determine relative source contributions for different spatial scales (nested catchments), climatic conditions and flow stages. Subsoil was the main source of fine sediment for all catchments (82%, SD=1.15) and the main N source at smaller scales (55-76%, SD=4.6-10.5), with an exception for the wet year and at the larger catchment, where surface soil was the dominant N source (55-61%, SD=3.6-9.9), though contributions were dependent on flow (59 680m3/s). C3 litter was the main source of organic C export for the two larger catchments (53%, SD=3.8) even though C4 grasses dominate the vegetation cover in these catchments. The sources of fine sediment, organic matter and N differ in subtropical catchments impacted by erosion, with the majority of C derived from C3 leaf litter and the majority of N derived from either subsoil or surface soil. Understanding these differences will assist management in reducing sediment, organic matter and N transfers in similar subtropical catchments while providing a quantitative foundation for testing C and N budgets. PMID- 27720248 TI - Allergen-specific IgE to food molecular components and age: From early childhood to adulthood. AB - BACKGROUND: Respiratory allergy is characterised by an IgE-mediated reaction. The immune system functions, including IgE production, progressively decline over time with growing up and ageing. Molecular-based allergy diagnostic defines sensitisation profile. This study aimed to evaluate the impact of age on serum allergen-specific IgE to molecular component levels in a large sample of subjects. METHODS: Serum IgE to: rCor a11, rPru p3, nJug r3, rAra h8, rGly m4, rCor a8, nPen m1, nAct d8, Bos d 8, and nGal d2 were assessed by ISAC method. Sera from 2795 patients, 1234 males (44.1%) and 1561 females (55.9%), median age 23 years (1st and 3rd quartiles: 9.7-43.7 years; age range: 1 month-103 years) were analysed. RESULTS: The number of positive tests (i.e. sensitisation) tended to increase between birth and school-age until young adulthood and then decreased. A similar age-dependent trend was observed considering the levels of each allergen components: the levels of each allergen component tended to increase until early adulthood, but Gal d 2 and Bos d 8 (rapidly diminishing), and then to decrease over time. However, the pattern is significantly dependent on each single tested food. CONCLUSIONS: Allergen-specific IgE production to food molecular components tend to reduce with ageing, but with differences between allergens. This phenomenon should be adequately evaluated managing allergic patients. PMID- 27720249 TI - Assessment of the performance of SMFCs in the bioremediation of PAHs in contaminated marine sediments under different redox conditions and analysis of the associated microbial communities. AB - The biodegradation of naphthalene, 2-methylnaphthalene and phenanthrene was evaluated in marine sediment microbial fuel cells (SMFCs) under different biodegradation conditions, including sulfate reduction as a major biodegradation pathway, employment of anode as terminal electron acceptor (TEA) under inhibited sulfate reducing bacteria activity, and combined sulfate and anode usage as electron acceptors. A significant removal of naphthalene and 2-methylnaphthalene was observed at early stages of incubation in all treatments and was attributed to their high volatility. In the case of phenanthrene, a significant removal (93.83+/-1.68%) was measured in the closed circuit SMFCs with the anode acting as the main TEA and under combined anode and sulfate reduction conditions (88.51+/ 1.3%). A much lower removal (40.37+/-3.24%) was achieved in the open circuit SMFCs operating with sulfate reduction as a major biodegradation pathway. Analysis of the anodic bacterial community using 16S rRNA gene pyrosequencing revealed the enrichment of genera with potential exoelectrogenic capability, namely Geoalkalibacter and Desulfuromonas, on the anode of the closed circuit SMFCs under inhibited SRB activity, while they were not detected on the anode of open circuit SMFCs. These results demonstrate the role of the anode in enhancing PAHs biodegradation in contaminated marine sediments and suggest a higher system efficiency in the absence of competition between microbial redox processes (under SRB inhibition), namely due to the anode enrichment with exoelectrogenic bacteria, which is a more energetically favorable mechanism for PAHs oxidation than sulfate. PMID- 27720251 TI - Elimination of the antibiotic norfloxacin in municipal wastewater, urine and seawater by electrochemical oxidation on IrO2 anodes. AB - The electrochemical degradation of the fluoroquinolone antibiotic norfloxacin (NOR) on Ti/IrO2 anodes, in several aqueous matrices was evaluated. For this purpose, initially the performance and degradation routes of the technology at several pH values (3.0, 6.5, 7.5 and 9.0) and in the presence of some of the most common anions in real water matrices (Cl-, HCO3-, SO42- and NO3-) were determined. The results showed that the degradation of NOR can occur through both direct elimination at the electrode surface and mediated oxidation, via the electrogeneration of oxidative agents, such as active chlorine species and percarbonate ions, which come from chloride and bicarbonate oxidation, respectively. Conversely, nitrate ions showed to inhibit the efficiency of the system. Concerning the pH, the efficiency of the process in the presence of chloride ions followed the order: 9.0>7.5>6.5>3.0; showing a strong dependence of the NOR speciation, and being the anionic form of the antibiotic the more susceptible to be oxidized. Furthermore, the identification of three primary NOR by-products demonstrated that the initial attack of the active chlorine species, mainly HOCl, occurred at the secondary amine of the piperazine ring followed by chlorination of the benzene ring. The precedent findings were crucial to understand the efficiency of the technology to eliminate NOR in synthetic complex matrices such as seawater, municipal wastewater and urine. The electrochemical oxidation showed to be promissory to eliminate NOR, and its associated antimicrobial activity, in such complexes matrices. Waters at basic pH containing chloride or bicarbonate ions, such as seawater or municipal wastewater showed to be the most adapted to the application of the technology. Additionally, nitrate ions or urea, found in some matrices like fresh urine, reduce the efficiency of the process. PMID- 27720252 TI - A framework for planning sustainable seawater desalination water supply. AB - A quantitative framework for sustainable desalination planning in metropolitan areas, which integrates the tools of mixed integer linear programming and life cycle assessment, is presented. The life cycle optimisation framework allows for optimal desalination planning by considering choices over intake type, staging and location of the infrastructure under different land-use, environmental and economic policies. Optimality is defined by the decision maker's selected objective function, being either an environmental impact or a levelised cost indicator. The framework was tested for future desalination planning scenarios in the northern metropolitan area of Perth, Western Australia. Results indicate that multi-staged construction and decentralised planning solutions may produce lower life cycle environmental impacts (58%) and at a lower levelised cost (24%) than a centralised desalination solution currently being considered by Western Australian water planners. Sensitivity analysis results suggest that the better environmental and economic performance of decentralised planning over centralised planning is highly sensitive to the proportion of land that can be made available for the siting of decentralised plants near the demand zone. Insight into land use policies is a critical factor to the initiation and success of decentralised solution in developed metropolitan areas. PMID- 27720253 TI - Biomonitoring of genotoxic effects and elemental accumulation derived from air pollution in community urban gardens. AB - Urban gardening is a growing global phenomenon with a positive impact on society. Despite several associated benefits, growing vegetables in urban gardens that are localized in highly polluted areas poses questions about the safety of the produced food. Therefore, the identification of risk factors that result in possible deleterious effects to human health is important for realizing all of the benefits to society. We evaluated the use of two biomonitoring methods in ten urban gardens of Sao Paulo city and one control site: the micronuclei frequencies for early tetrads of Tradescantia pallida (Rose) Hunt. cv. "Purpurea" Boom (hereafter, Trad-MCN) as a short-term indicator of genotoxic response and tree barks to quantify the accumulation of traffic-related chemical elements as a long term biomarker of air pollution in urban gardens. Mature plants of Tradescantia pallida were exposed in each garden, and their inflorescences were sampled over three months. A random set of 300 early tetrads in 13 to 21 slides per garden were evaluated for micronuclei frequencies. Elemental concentrations in 428 tree barks samples from 107 different trees in the areas surrounding urban gardens were quantified using an energy dispersive X-ray fluorescence spectrometer. The frequency of Trad-MCN has a significant correlation with traffic variables and chemical elements related to road dust and tailpipe emissions deposited in tree barks. Negative associations between Trad-MCN and both the distance through traffic and the presence of vertical obstacles were observed in the community gardens. The Mn/Zn concentrations in tree barks were associated with increased Trad-MCN. PMID- 27720254 TI - The application of iron-based technologies in uranium remediation: A review. AB - Remediating uranium contamination is of worldwide interest because of the increasing release of uranium from mining and processing, nuclear power leaks, depleted uranium components in weapons production and disposal, and phosphate fertilizer in agriculture activities. Iron-based technologies are attractive because they are highly efficient, inexpensive, and readily available. This paper provides an overview of the current literature that addresses the application of iron-based technologies in the remediation of sites with elevated uranium levels. The application of iron-based materials, the current remediation technologies and mechanisms, and the effectiveness and environmental safety considerations of these approaches were discussed. Because uranium can be reduced and reoxidized in the environment, the review also proposes strategies for long-term in situ remediation of uranium. Unfortunately, iron-based materials (nanoscale zerovalent iron and iron oxides) can be toxic to microorganisms. As such, further studies exploring the links among the fates, ecological impacts, and other environmentally relevant factors are needed to better understand the constraints on using iron-based technologies for remediation. PMID- 27720255 TI - Low-drift nozzles vs. standard nozzles for pesticide application in the biological efficacy trials of pesticides in apple pest and disease control. AB - The coarse spray air-induction nozzles have documented pesticide drift reducing potential and hence pose lower risk of environmental pollution than the standard fine spray hollow cone nozzles. However, it is questioned that use of the low drift nozzles might not provide as effective crop protection as the standard nozzles. The objective of work was to assess the pest and disease control efficacy as affected by spray volume rate and nozzle type. The experiment was carried out in apple orchard, cv Jonagold/M26. The evaluated treatments were combinations of three spray volume rates: 250, 500 and 750lha-1, and two types of nozzles: hollow cone nozzles generating very fine spray, and flat fan air induction nozzles producing coarse droplets. The biological performance of treatments was determined based on severity of diseases: apple scab (Venturia inaequalis), powdery mildew (Podosphaera leucotricha) and bull's eye rot (Pezicula spp.), as well as population or damage caused by pests: green apple aphid (Aphis pomi), rosy apple aphid (Dysaphis plantaginea Pass.), woolly apple aphid (Eriosoma lanigerum), apple rust mite (Aculus schlechtendali) and apple blossom weevil (Anthonomus pomorum L.). In general apple scab was equally controlled by all treatments. Only in the years of high infection pressure efficacy of powdery mildew control was better for fine spray nozzles and high volume rates. Green and rosy apple aphids were better controlled with higher volume rates, though significance of the advantage over the lower rates was occasional. No effect of spray quality on efficacy of aphid and mite control was found for any spray volume rate. Better control of apple blossom weevil and woolly apple aphid was achieved with the high spray volume rate providing heavy coverage to the point of run-off. The air induction nozzles having drift reducing potential are biologically efficacious alternative to conventional hollow cone nozzles. PMID- 27720256 TI - Hydrological and thermal effects of hydropeaking on early life stages of salmonids: A modelling approach for implementing mitigation strategies. AB - Alterations in hydrological and thermal regimes can potentially affect salmonid early life stages development and survival. The dewatering of salmon spawning redds due to hydropeaking can lead to mortality in early life stages, with higher impact on the alevins as they have lower tolerance to dewatering than the eggs. Flow-related mitigation measures can reduce early life stage mortality. We present a set of modelling tools to assess impacts and mitigation options to minimise the risk of mortality in early life stages in hydropeaking rivers. We successfully modelled long-term hydrological and thermal alterations and consequences for development rates. We estimated the risk of early life stages mortality and assessed the cost-effectiveness of implementing three release related mitigation options (A,B,C). The economic cost of mitigation was low and ranged between 0.7% and 2.6% of the annual hydropower production. Options reducing the flow during spawning (B and C) in addition to only release minimum flows during development (A) were considered more effective for egg and alevin survival. Options B and C were however constraint by water availability in the system for certain years, and therefore only option A was always feasible. The set of modelling tools used in this study were satisfactory and their applications can be useful especially in systems where little field data is available. Targeted measures built on well-informed modelling tools can be tested on their effectiveness to mitigate dewatering effects vs. the hydropower system capacity to release or conserve water for power production. Environmental flow releases targeting specific ecological objectives can provide better cost effective options than conventional operational rules complying with general legislation. PMID- 27720257 TI - The drinking water contamination crisis in Flint: Modeling temporal trends of lead level since returning to Detroit water system. AB - Since Flint returned to its pre-crisis source of drinking water close to 25,000 water samples have been collected and tested for lead and copper in >10,000 residences. This paper presents the first analysis and time trend modeling of lead data, providing new insights about the impact of this intervention. The analysis started with geocoding all water lead levels (WLL) measured during an 11 month period following the return to the Detroit water supply. Each data was allocated to the corresponding tax parcel unit and linked to secondary datasets, such as the composition of service lines, year built, or census tract poverty level. Only data collected on residential parcels within the City limits were used in the analysis. One key feature of Flint data is their collection through two different sampling initiatives: (i) voluntary or homeowner-driven sampling whereby concerned citizens decided to acquire a testing kit and conduct sampling on their own (non-sentinel sites), and (ii) State-controlled sampling where data were collected bi-weekly at selected sites after training of residents by technical teams (sentinel sites). Temporal trends modeled from these two datasets were found to be statistically different with fewer sentinel data exceeding WLL thresholds ranging from 10 to 50MUg/L. Even after adjusting for housing characteristics the odds ratio (OR) of measuring WLL above 15MUg/L at non sentinel sites is significantly >1 (OR=1.480) and it increases with the threshold (OR=2.055 for 50MUg/L). Joinpoint regression showed that the city-wide percentage of WLL data above 15MUg/L displayed four successive trends since the return to Detroit Water System. Despite the recent improvement in water quality, the culprit for differences between sampling programs needs to be identified as it impacts exposure assessment and might influence whether there is compliance or not with the Lead and Copper Rule. PMID- 27720258 TI - Abnormal increase of Mn and TP concentrations in a temperate reservoir during fall overturn due to drought-induced drawdown. AB - Due to global warming, some regions of Earth may face frequent and severe droughts in the future, leading to the deterioration of surface water quality. In this study, we investigated the effects of drought-induced drawdown on the water quality of the Zhoucun Reservoir, Shandong Province, East China, during the fall overturn. Field surveys were conducted during stratification (April-November) over three standard years 2012, 2013, and 2014, and over the El Nino event of 2015. Temporal and vertical variations of the physical and chemical indexes were investigated during monitoring. Results show that after the formation of stratification, the hypolimnion rapidly shifted to anaerobic conditions, with the accumulation of pollutants such as manganese (Mn) and total phosphorous (TP). Due to the extreme El Nino event in 2015, both the upper and lower metalimnion limits moved down along with the water level in summer, which resulted in the transfer of hypolimnion water to the metalimnion. In summer 2015, large amounts of pollutants were measured in the metalimnion: a phenomenon that did not occur at the same period of the standard years. At the beginning of the overturn in 2015, the water quality of the whole reservoir deteriorated when the metalimnion water shifted to the epilimnion. Mn and TP concentrations in the epilimnion reached 0.202mg/L and 0.086mg/L, respectively, which are significantly higher than those in the standard years. Although the tributary rivers entered the epilimnion of the reservoir during the overturn, Mn and TP concentrations of the inflow were only of 0.049-0.072mg/L and 0.033-0.047mg/L, respectively, indicating that these rivers were not the source of the high TP and high Mn concentrations in the epilimnion. Hence, we conclude that more attention should be paid to the metalimnion position and the vertical distribution of pollutants when studying lakes and reservoirs experiencing droughts. PMID- 27720259 TI - TGF-beta1 promotes linear invadosome formation in hepatocellular carcinoma cells, through DDR1 up-regulation and collagen I cross-linking. AB - Transforming growth factor-beta1 (TGF-beta1) is an important player in chronic liver diseases inducing fibrogenesis and hepatocellular carcinoma (HCC) development. TGF-beta1 promotes pleiotropic modifications at the cellular and matrix microenvironment levels. TGF-beta1 was described to enhance production of type I collagen and its associated cross-linking enzyme, the lysyl oxidase-like2 (LOXL2). In addition, TGF-beta1 and type I collagen are potent inducers of invadosomes. Indeed, type I collagen fibers induce the formation of active linear invadosomes through the discoidin domain receptor 1 (DDR1). The goal of our study was to address the role of TGF-beta1 in collagen cross-linking and its impact on the formation of linear invadosomes in liver cancer cells. We first report a significant correlation between expressions of TGF-beta1, and type I collagen, LOXL2, DDR1 and MT1-MMP in human HCCs. We demonstrate that TGF-beta1 promotes a Smad4-dependent up-regulation of DDR1, together with LOXL2, in cultured HCC cells. Moreover, we show that LOXL2-induced collagen cross-linking enhances linear invadosome formation. Altogether, our data demonstrate that TGF-beta1 favors linear invadosome formation through the expressions of both the inducers, such as collagen and LOXL2, and the components such as DDR1 and MT1-MMP of linear invadosomes in cancer cells. Meanwhile, our data uncover a new TGF-beta1 dependent regulation of DDR1 expression. PMID- 27720261 TI - Health inequalities: Mexico's greatest challenge. PMID- 27720260 TI - Dissonant health transition in the states of Mexico, 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013. AB - BACKGROUND: Child and maternal health outcomes have notably improved in Mexico since 1990, whereas rising adult mortality rates defy traditional epidemiological transition models in which decreased death rates occur across all ages. These trends suggest Mexico is experiencing a more complex, dissonant health transition than historically observed. Enduring inequalities between states further emphasise the need for more detailed health assessments over time. The Global Burden of Diseases, Injuries, and Risk Factors Study 2013 (GBD 2013) provides the comprehensive, comparable framework through which such national and subnational analyses can occur. This study offers a state-level quantification of disease burden and risk factor attribution in Mexico for the first time. METHODS: We extracted data from GBD 2013 to assess mortality, causes of death, years of life lost (YLLs), years lived with disability (YLDs), disability-adjusted life-years (DALYs), and healthy life expectancy (HALE) in Mexico and its 32 states, along with eight comparator countries in the Americas. States were grouped by Marginalisation Index scores to compare subnational burden along a socioeconomic dimension. We split extracted data by state and applied GBD methods to generate estimates of burden, and attributable burden due to behavioural, metabolic, and environmental or occupational risks. We present results for 306 causes, 2337 sequelae, and 79 risk factors. FINDINGS: From 1990 to 2013, life expectancy from birth in Mexico increased by 3.4 years (95% uncertainty interval 3.1-3.8), from 72.1 years (71.8-72.3) to 75.5 years (75.3-75.7), and these gains were more pronounced in states with high marginalisation. Nationally, age-standardised death rates fell 13.3% (11.9-14.6%) since 1990, but state-level reductions for all-cause mortality varied and gaps between life expectancy and years lived in full health, as measured by HALE, widened in several states. Progress in women's life expectancy exceeded that of men, in whom negligible improvements were observed since 2000. For many states, this trend corresponded with rising YLL rates from interpersonal violence and chronic kidney disease. Nationally, age standardised YLL rates for diarrhoeal diseases and protein-energy malnutrition markedly decreased, ranking Mexico well above comparator countries. However, amid Mexico's progress against communicable diseases, chronic kidney disease burden rapidly climbed, with age-standardised YLL and DALY rates increasing more than 130% by 2013. For women, DALY rates from breast cancer also increased since 1990, rising 12.1% (4.6-23.1%). In 2013, the leading five causes of DALYs were diabetes, ischaemic heart disease, chronic kidney disease, low back and neck pain, and depressive disorders; the latter three were not among the leading five causes in 1990, further underscoring Mexico's rapid epidemiological transition. Leading risk factors for disease burden in 1990, such as undernutrition, were replaced by high fasting plasma glucose and high body-mass index by 2013. Attributable burden due to dietary risks also increased, accounting for more than 10% of DALYs in 2013. INTERPRETATION: Mexico achieved sizeable reductions in burden due to several causes, such as diarrhoeal diseases, and risks factors, such as undernutrition and poor sanitation, which were mainly associated with maternal and child health interventions. Yet rising adult mortality rates from chronic kidney disease, diabetes, cirrhosis, and, since 2000, interpersonal violence drove deteriorating health outcomes, particularly in men. Although state inequalities from communicable diseases narrowed over time, non-communicable diseases and injury burdens varied markedly at local levels. The dissonance with which Mexico and its 32 states are experiencing epidemiological transitions might strain health-system responsiveness and performance, which stresses the importance of timely, evidence-informed health policies and programmes linked to the health needs of each state.

PMID- 27720263 TI - Characteristics and outcomes of patients with postoperative cardiovascular pseudoaneurysms. AB - BACKGROUND: Data regarding long-term outcomes in cardiovascular pseudoaneurysms are sparse. In patients with prior cardiovascular surgery, we sought to assess characteristics and outcomes in patients with cardiovascular pseudoaneurysms (excluding ischemic left ventricular pseudoaneurysms). METHODS: We included 114 patients (mean age, 57 +/- 16 years; 70% were men) with prior cardiovascular surgery who presented with paravalvular (n = 71, 59 aortic and 12 mitral valve) and ascending aortic (n = 43) pseudoaneurysms (27% with systemic infection). Baseline, surgical, and follow-up data were recorded. A composite end point of stroke or death during follow-up was recorded. RESULTS: Additive European System for Cardiac Operative Risk Evaluation was high (10%), and 81% of patients underwent another redo cardiovascular surgery. Over a mean follow-up period of 5.2 +/- 4 years, there were 37 (32%) composite events (32 deaths and 5 strokes). Within the surgical subgroup, there were 10 (11%) composite events during the in hospital stay. The 1-, 2-, 5-, and 10-year freedom from composite events were 86%, 82%, 74%, and 55%, respectively. Additive European System for Cardiac Operative Risk Evaluation (hazard ratio, 1.14) and presence of a documented systemic infection (hazard ratio, 3.90) were associated with a higher rate of composite events, whereas subsequent cardiovascular surgery as a time-dependent covariate hazard ratio (hazard ratio, 0.30) was associated with improved freedom from composite events (all P < .05). CONCLUSIONS: Patients with a history of cardiovascular surgery in whom cardiovascular pseudoaneurysms subsequently develop have a high rate of short- and long-term adverse events. A higher additive European System for Cardiac Operative Risk Evaluation and documented systemic infection were associated with a higher rate of composite events, whereas cardiovascular surgery (to correct cardiovascular pseudoaneurysms) during follow-up was associated with improved freedom from adverse events. PMID- 27720265 TI - Brain parenchymal fraction in an age-stratified healthy population - determined by MRI using manual segmentation and three automated segmentation methods. AB - BACKGROUND AND PURPOSE: Brain atrophy is a prominent feature in many neurodegenerative diseases, such as multiple sclerosis, but age-related decrease of brain volume occurs regardless of pathological neurodegeneration. Changes in brain volume can be described by use of the brain parenchymal fraction (BPF), most often defined as the ratio of total brain parenchyma to total intracranial space. The BPF is of interest both in research and in clinical practice. To be able to properly interpret this variable, the normal range of BPF must be known. The objective of this study is to present normal values for BPF, stratified by age, and compare manual BPF measurement to three automated methods. MATERIALS AND METHODS: The BPFs of 106 healthy individuals aged 21 to 85 years were determined by the automated segmentation methods SyMap, VBM8 and SPM12. In a subgroup of 54 randomly selected individuals, the BPF was also determined by manual segmentation. RESULTS: The median (IQR) BPFs of the whole study population were 0.857 (0.064), 0.819 (0.028) and 0.784 (0.073) determined by SyMap, VBM8 and SPM12, respectively. The BPF decreased with increasing age. The correlation coefficients between manual segmentation and SyMap, VBM8 and SPM12 were 0.93 (P<0.001), 0.77 (P<0.001) and 0.56 (P<0.001), respectively. CONCLUSIONS: There was a clear relationship between increasing age and decreasing BPF. Knowledge of the range of normal BPF in relation to age group will help in the interpretation of BPF data. The automated segmentation methods displayed varying degrees of similarity to the manual reference, with SyMap being the most similar. PMID- 27720266 TI - Burn leads to long-term elevated admissions to hospital for gastrointestinal disease in a West Australian population based study. AB - BACKGROUND: While the most obvious impact of burn is on the skin, systemic responses also occur after burn, including intestinal inflammation. The objective of this study was to assess if burns are associated with increased long-term admissions for gastrointestinal diseases. METHODS: A population-based longitudinal study using linked hospital morbidity and death data from Western Australia was undertaken of adults aged at least 15 years when hospitalized for a first burn (n=20,561) in 1980-2012. A frequency matched non-injury comparison cohort was randomly selected from Western Australia's birth registrations and electoral roll (n=80,960). Crude admission rates and summed days in hospital for digestive diseases were calculated. Negative binomial and Cox proportional hazards regression modeling were used to generate incidence rate ratios (IRR) and hazard ratios (HR), respectively. RESULTS: After adjustment for demographic factors and pre-existing health status, the burn cohort had 1.54 times (95% confidence interval (CI): 1.47-1.62) as many admissions and almost three times the number of days in hospital with a digestive system diagnosis (IRR, 95% CI: 2.90, 2.60-3.25) than the uninjured cohort. Significantly elevated adjusted post burn incident rates were identified, with the risk decreasing with increasing time: in the first month (HR, 95% CI: 3.02, 1.89-4.82), from one month to five years (HR, 95% CI: 1.42, 1.31-1.54), and from five to twenty years after burn (HR, 95% CI: 1.13, 1.06-1.20). CONCLUSIONS: Findings of increased hospital admission rates and prolonged length of hospital stay for gastrointestinal diseases in the burn cohort provide evidence to support that burns have effects that persist long after the initial injury. PMID- 27720267 TI - Enhancement of stem cell differentiation to osteogenic lineage on hydroxyapatite coated hybrid PLGA/gelatin nanofiber scaffolds. AB - A combination of polymeric materials and bioceramics has recently received a great deal of attention for bone tissue engineering applications. In the present study, hybrid nanofibrous scaffolds were fabricated from PLGA and gelatin via electrospinning and then were coated with hydroxyapatite (HA). They were then characterized and used in stem cell culture studies for the evaluation of their biological behavior and osteogenic differentiation in vitro. This study showed that all PLGA, hybrid PLGA/gelatin and HA-PLGA/gelatin scaffolds were composed of ultrafine fibers with smooth morphology and interconnected pores. The MTT assay confirmed that the scaffolds can support the attachment and proliferation of stem cells. During osteogenic differentiation, bone-related gene expression, ALP activity and biomineralization on HA-PLGA/gelatin scaffolds were higher than those observed on other scaffolds and TCPS. PLGA/gelatin electrospun scaffolds also showed higher values of these markers than TCPS. Taking together, it was shown that nanofibrous structure enhanced osteogenic differentiation of adipose tissue derived stem cells. Furthermore, surface-coated HA stimulated the effect of nanofibers on the commitment of stem cells toward osteolineage. In conclusion, HA-PLGA/gelatin electrospun scaffolds were demonstrated to have significant potential for bone tissue engineering applications. PMID- 27720268 TI - Development of inactivated poliovirus vaccine from Sabin strains: A progress report. AB - The Global Polio Eradication Initiative (GPEI) has seen significant progress since it began in 1988, largely due to the worldwide use of oral poliovirus vaccine (OPV). In order to achieve polio eradication the global cessation of OPV is necessary because OPV contains live attenuated poliovirus, which in rare circumstances could re-gain wild poliovirus (WPV) characteristics with potential to establish transmission. The GPEI endgame strategy for the period 2013-2018 recommends the globally synchronised sequential cessation of the Sabin strains contained in the OPV, starting with type 2 Sabin. The withdrawal of Sabin type 2 took place in April 2016, with the introduction of at least one dose of inactivated poliovirus vaccine (IPV) as a risk mitigation strategy. The introduction of IPV into 126 countries since 2013 has required a rapid scale-up of IPV production by the two manufacturers supplying the global public sector market. This scale-up has been fraught with challenges, resulting in reductions of 40-50% of initial supply commitments. Consequently, 22 countries will not be supplied until 2018, and another 23 countries will experience serious stock-outs. In the last decade repeated calls-for-action were made to the global community to invigorate their vision and investment in developing "new poliovirus vaccines" including the development of IPV from less-virulent strains, such as Sabin-IPV (S IPV). The conventional Salk-IPV production is limited to high-income industrialized-country manufacturers due to the containment requirements (i.e., high sanitation, low force-of-poliovirus-infection, and high population immunity). The use of Sabin strains in the production of S-IPV carries a lower biosafety risk, and was determined to be suitable for production in developing countries, expanding the manufacturing base and making IPV more affordable and accessible in the long term. Significant progress in the S-IPV has been made since 2006. S-IPV is now licensed as S-IPV in Japan and as standalone S-IPV in China, demonstrating the feasibility of this vaccine. In addition, production process improvements can further reduce the cost of production. The latter are critical to the economic success of this vaccine in the global market. We summarize the progress made to date in S-IPV technology, the scientific data and economic evidence in support of S-IPV development. PMID- 27720269 TI - Introduction. PMID- 27720270 TI - Use of computer-assisted sperm analysis and flow cytometry to detect seasonal variations of bovine semen quality. AB - Seasonal fluctuations of climate are considered a major factor affecting spermatogenesis and semen quality in the bovine. Our study aimed to investigate the effect of season on functional parameters of frozen-thawed bovine semen using computer-assisted sperm analysis (CASA) and flow cytometry. For this purpose, 86 ejaculates were collected from five mature Holstein-Friesian bulls kept under subtropical conditions during summer (August to September; n = 43) and winter (December to January; n = 43) months. Semen was diluted with a Tris-egg yolk based extender and frozen at -196 degrees C. Computer-assisted sperm analysis was performed immediately after thawing (0h) and after 3 hours of incubation (3h) to evaluate the percentage (%) of total motile, progressively motile, and rapidly motile sperm. In addition, the average path, curvilinear, and straight-line velocities as well as the amplitude of lateral head displacement of sperm were determined. The percentages of sperm with intact plasma membrane and acrosome (PMAI, %), with high mitochondrial membrane potential (HMMP, %), with low intracellular Ca+2 levels (LOW-Ca+2, %), and with high DNA fragmentation index (DFI%, %) were flow cytometrically determined at 0 and 3h. The survival rate of sperm under hypotonic conditions (HYPO-SURV, %) and the percentage of sperm with inducible acrosome reaction (IAR, %) were assessed using flow cytometry at 0 and 3h, respectively. The fixed effect of season (winter vs. summer) on the quality parameters of sperm was explored by applying linear mixed-effects models. The results showed an improvement of all CASA parameters, except for the straight line velocity (P > 0.05) in winter compared with summer for both unincubated and incubated sperm (P < 0.01 in all cases). Ejaculates collected in summer had lower values of IAR (P < 0.001) as well as PMAI, HMMP, and LOW-Ca+2 at 0 and 3h (P < 0.01 in all cases). On the contrary, HYPO-SURV and DFI% (at 0 and 3h) were not affected by season (P > 0.05 in all cases). Concluding, the employment of CASA and flow cytometry revealed season-related alterations in the functional status of cryopreserved bovine sperm, which suggest an adverse effect of summer heat stress on motility, plasma membrane and acrosome integrity, inducibility of acrosome reaction, mitochondrial function and intracellular Ca+2 content, but not on the DNA integrity of sperm after freezing-thawing. PMID- 27720271 TI - Sustained Elevation of Vascular Endothelial Growth Factor and Angiopoietin-2 Levels After Transcatheter Aortic Valve Replacement. AB - BACKGROUND: Transcatheter aortic valve replacement (TAVR) exposes the systemic vasculature to increased mechanical forces. Endothelial adaptation to mechanical stimuli is associated with angiogenic activation through various growth factors. We studied the potential angiogenic shift evoked by TAVR. METHODS: From a cohort of 69 consecutive patients undergoing TAVR, we excluded patients with conditions known to affect angiogenic factors, and serum vascular endothelial growth factor (VEGF) and angiopoietin (Ang)-1 and Ang-2 were assessed by ELISA. We assessed in vitro the properties of endothelial cells after exposure to serum collected from patients undergoing TAVR using adhesion, migration, and Matrigel angiogenesis assays. The correlation between changes in angiogenic factors and cardiac functions was evaluated on 30- day echocardiograms. RESULTS: The study population consisted of 46 patients (82 +/- 5 years). Two days after TAVR the post/pre TAVR ratio of VEGF, Ang-1, and Ang-2 was 5.38 +/- 4 (P < 0.001), 1.05 +/- 0.49 (P = 0.27), and 4.65 +/- 2.01 (P < 0.001), respectively. The increase in VEGF and Ang 2 showed a significant correlation (r = 0.609; P < 0.001), but no correlation was found with hemolysis or tissue injury markers. Patients with relatively low levels of VEGF or an Ang-2 rise had more severe aortic stenosis and coronary disease at baseline. Exposure of endothelial cells to post-TAVR serum induced adhesion, migration, and tube formation compared with pre-TAVR serum. An increase in VEGF levels correlated with improvement in pulmonary systolic pressure and a right ventricular fractional area change at 30 days, (r = 0.54 and r = 0.48, respectively; P < 0.01). CONCLUSIONS: Sustained elevation of VEGF and Ang-2 levels occur after TAVR, reflecting a systemic angiogenic shift. A rise in VEGF levels is associated with a decrease in pulmonary blood pressure in patients undergoing TAVR.

AB - BACKGROUND: Although epicardial adipose tissue (EAT) volume is associated with increased incidence of coronary artery disease (CAD), its role in myocardial systolic dysfunction is unclear. The present study aimed to identify independent determinants of EAT volume in patients without obstructive CAD, and to evaluate the association between EAT volume (vs other measures of obesity) and myocardial systolic strain analysis. METHODS: We prospectively recruited 130 patients without obstructive CAD on contrast-enhanced cardiac computed tomography imaging and normal left ventricular ejection fraction on 3-dimensional (3D) echocardiography. EAT volume was quantified from cardiac computed tomography imaging, and 3D multidirectional (longitudinal, circumferential, radial, and area) strain were measured. RESULTS: The mean EAT volume was 97.5 +/- 43.7 cm3. In multivariable analysis, measures of obesity (body mass index [P = 0.007] and waist/hip ratio [P = 0.001]) were independently associated with larger EAT volume. EAT volume was correlated with 3D global longitudinal (r = 0.601; P < 0.001), circumferential (r = 0.375; P < 0.001), radial (r = -0.546; P < 0.001), and area (r = 0.558; P < 0.001) strain. In multivariable analyses, epicardial fat volume was the strongest predictor of 3D global longitudinal (standardized beta = 0.512; P < 0.001), circumferential (standardized beta = 0.242; P = 0.006), radial (standardized beta = -0.422; P < 0.001), and area (standardized beta = 0.428; P < 0.001) strain. In contrast, other measures of obesity including body mass index and waist/hip ratio were not independent determinants of 3D multidirectional global strain (all P > 0.05). CONCLUSIONS: EAT volume is independently associated with impaired myocardial systolic function despite preserved 3D left ventricular ejection fraction and absence of obstructive CAD, and might play a significant role in the pathophysiology of diabetic, obesity, and metabolic heart disease. PMID- 27720273 TI - Inflammatory and metabolic responses to dietary intervention differ among individuals at distinct cardiometabolic risk levels. AB - OBJECTIVE: The aim of this study was to investigate the effects of two interventions in breakfast with different fatty acid content on metabolic and inflammatory biomarkers in individuals at different cardiovascular risk levels. METHODS: This crossover clinical trial included 80 overweight participants who were grouped according to the presence of metabolic syndrome (MetS). The participants received two isocaloric breakfast interventions for 4 wk, with a 2 wk washout. The "Brazilian" breakfast was enriched with saturated fat, whereas the "modified" meal was enriched with unsaturated fatty acids and fibers. Repeated-measures analysis of variance was used to compare dietary data, and Student's t or Wilcoxon tests were used to compare clinical and inflammatory variables. A chi2 test was employed to compare frequencies. RESULTS: Frequencies of MetS increased after the Brazilian breakfast and decreased after the modified meal. Significant reduction in mean values of WC and diastolic blood pressure (DBP) and elevation in high-density lipoprotein cholesterol were detected at the end of the modified intervention. Participants with or without the MetS exhibited contrasting responses to the modified breakfast: respectively, significant changes in DBP levels (-3.7 +/- 6.9 versus -0.5 +/- 6.9 mm Hg; P < 0.05), plasma glucose (-3 +/- 7.3 versus 3 +/- 7.4 mg/dL; P < 0.05), and apolipoprotein-B (-0.1 +/- 0.6 versus 0.2 +/- 0.3 mg/mL; P < 0.05), interferon-gamma (-0.6 +/- 1.2 versus 0.1 +/- 1.3 pg/mL; P < 0.05), and tumor necrosis factor-alpha concentrations (0.4 +/- 3.6 versus -0.8 +/- 2.8 pg/mL; P < 0.05) were observed. CONCLUSIONS: Dietary intervention of small magnitude, for a short period, was able to improve traditional risk factors for cardiovascular disease and inflammatory markers, as well as the frequency of MetS. Responses to dietary interventions of individuals at different levels of cardiovascular risk should be examined through different biomarkers. PMID- 27720274 TI - Tumor necrosis factor-alpha inhibitor-induced psoriasis: Systematic review of clinical features, histopathological findings, and management experience. AB - BACKGROUND: Tumor necrosis factor-alpha (TNF-alpha) inhibitors have been reported to induce new-onset psoriasis. OBJECTIVE: To better define the demographic, clinical features, and treatment approach of TNF-alpha inhibitor-induced psoriasis. METHODS: Systematic review of published cases of TNF-alpha inhibitor induced psoriasis. RESULTS: We identified 88 articles with 216 cases of new-onset TNF-alpha inhibitor-induced psoriasis. The mean age at psoriasis onset was 38.5 years. The most common underlying diseases were Crohn disease (40.7%) and rheumatoid arthritis (37.0%). Patients underwent TNF-alpha therapy for an average of 14.0 months before psoriasis onset with 69.9% of patients experiencing onset within the first year. The majority of patients received skin-directed therapy, though patients who discontinued TNF therapy had the greatest resolution of symptoms (47.7%) compared with those who switched to a different TNF agent (36.7%) or continued therapy (32.9%). LIMITATIONS: Retrospective review that relies on case reports and series. CONCLUSION: While TNF-alpha inhibitor cessation may result in resolution of induced psoriasis, lesions may persist. Decisions regarding treatment should be weighed against the treatability of TNF alpha inhibitor-induced psoriasis, the severity of the background rheumatologic or gastrointestinal disease, and possible loss of efficacy with cessation followed by retreatment. Skin-directed therapy is a reasonable initial strategy except in severe cases.

AB - PURPOSE: To evaluate postoperative variation trends of unilateral cleft lip by stages, and to analyze influential factors of nasolabial symmetry. MATERIALS AND METHODS: A total of 145 patients with unilateral cleft lip were treated by the modified Mohler or Tennison-Randall technique, and received routine anti-scarring treatment postoperatively. Photogrammetry was applied to respectively measure 5 indices by stages preoperatively, the first week (1 w), the third month (3 m), the sixth month (6 m), and the first year (1 y) postoperatively. Then we calculated the symmetry ratio and drew line charts. Student t tests were used for any group differences; linear regression analysis was used to examine which postoperative stage correlated best with the preoperative stage; cluster analysis was used to classify the severity of the cleft according to preoperative SRsn cphi, which was used to predict the operative difficulty and to select an appropriate technique. RESULTS: The Mohler technique yielded a more symmetric result. With the Tennison-Randall technique, the alar base was more lateral and downward, and the lip height on cleft side seemed longer. A stable effect emerged around 1 year after surgery with both techniques. Conspicuous scars appeared at 3 months, most scars gradually fade at 6 months, and the total evolution took around 1 year. Scars from the Mohler technique fluctuated across a larger range. Preoperative SRsn-cphi of the two techniques had statistical significance and was adopted as the basis for cluster analysis. The critical value was 0.670. The Mohler technique attained an almost identical effect in each interval, whereas the Tennison-Randall technique was better in the interval that SRsn-cphi <0.670. CONCLUSIONS: Preoperative SRsn-cphi can be the evaluation index of severity; the modified Mohler technique is more broadly applicable to differences in severity than is the Tennison-Randall technique. PMID- 27720275 TI - Combined soft and skeletal tissue modelling of normal and dysmorphic midface postnatal development. AB - BACKGROUND: Midface hypoplasia as exemplified by Treacher Collins Syndrome (TCS) can impair appearance and function. Reconstruction involves multiple invasive surgeries with variable long-term outcomes. This study aims to describe normal and dysmorphic midface postnatal development through combined modelling of skeletal and soft tissues and to develop a surgical evaluation tool. MATERIALS AND METHODS: Midface skeletal and soft tissue surfaces were extracted from computed tomography scans of 52 control and 14 TCS children, then analysed using dense surface modelling. The model was used to describe midface growth, morphology, and asymmetry, then evaluate postoperative outcomes. RESULTS: Parameters responsible for the greatest variation in midface size and shape showed differences between TCS and controls with close alignment between skeletal and soft tissue models. TCS children exhibited midface dysmorphology and hypoplasia when compared with controls. Asymmetry was also significantly higher in TCS midfaces. Combined modelling was used to evaluate the impact of surgery in one TCS individual who showed normalisation immediately after surgery but reversion towards TCS dysmorphology after 1 year. CONCLUSION: This is the first quantitative analysis of postnatal midface development using combined modelling of skeletal and soft tissues. We also provide an approach for evaluation of surgical outcomes, laying the foundations for future development of a preoperative planning tool. PMID- 27720277 TI - Dosimetric and radiobiological comparison of TG-43 and Monte Carlo calculations in 192Ir breast brachytherapy applications. AB - PURPOSE: To investigate the clinical significance of introducing model based dose calculation algorithms (MBDCAs) as an alternative to TG-43 in 192Ir interstitial breast brachytherapy. MATERIALS AND METHODS: A 57 patient cohort was used in a retrospective comparison between TG-43 based dosimetry data exported from a treatment planning system and Monte Carlo (MC) dosimetry performed using MCNP v. 6.1 with plan and anatomy information in DICOM-RT format. Comparison was performed for the target, ipsilateral lung, heart, skin, breast and ribs, using dose distributions, dose-volume histograms (DVH) and plan quality indices clinically used for plan evaluation, as well as radiobiological parameters. RESULTS: TG-43 overestimation of target DVH parameters is statistically significant but small (less than 2% for the target coverage indices and 4% for homogeneity indices, on average). Significant dose differences (>5%) were observed close to the skin and at relatively large distances from the implant leading to a TG-43 dose overestimation for the organs at risk. These differences correspond to low dose regions (<50% of the prescribed dose), being less than 2% of the prescribed dose. Detected dosimetric differences did not induce clinically significant differences in calculated tumor control probabilities (mean absolute difference <0.2%) and normal tissue complication probabilities. CONCLUSION: While TG-43 shows a statistically significant overestimation of most indices used for plan evaluation, differences are small and therefore not clinically significant. Improved MBDCA dosimetry could be important for re-irradiation, technique inter comparison and/or the assessment of secondary cancer induction risk, where accurate dosimetry in the whole patient anatomy is of the essence. PMID- 27720279 TI - Bone Marrow Aspirate Evaluation. AB - Important steps in bone marrow aspirate evaluation include determining if bone marrow evaluation is indicated; using appropriate aspirate collection, smear preparation, and staining techniques; and performing a systematic approach for the cytologic evaluation. The cytologic evaluation of bone marrow requires knowledge of the morphology of bone marrow cell types, the proportion of these cell types normally present, and the ability to evaluate overall cellularity of bone marrow. Accurate interpretation of bone marrow cytologic findings depends on evaluation of a current complete blood cell count. These components are the pillars of getting the most useful information in the diagnosis of hematologic disorders. PMID- 27720280 TI - Preanalytical Considerations for Joint Fluid Evaluation. AB - Synovial fluid analysis is a key component of the minimum database needed to diagnose and manage primary and secondary articular joint disorders. Unfortunately, preanalytical variables can drastically alter samples submitted for evaluation to veterinary laboratories and it is considered the stage at which most laboratory error occurs. This article addresses common sources of preanalytical variability and error that are seen in veterinary medicine. With consistent quality control and reporting of specimens, downstream clinical decision making and management of patients can be accelerated and improved. PMID- 27720278 TI - Histopathologic Validation of Grayscale Carotid Plaque Characteristics Related to Plaque Vulnerability. AB - Inflammation and angiogenesis play major roles in carotid plaque vulnerability. The purpose of this study was to determine whether gray-scale features of carotid plaques are associated with histologic markers for inflammation. Thirty-eight individuals completed a dedicated research carotid ultrasound exam before carotid endarterectomy. Gray-scale analysis was performed on plaque images to measure plaque echogenicity (gray-scale median [GSM] pixel brightness), plaque area, presence of discrete white areas (DWAs) and the percent of black area near the lumen on any one component of the plaque. Plaques with higher ultrasound GSM had greater percent calcification (p = 0.013) on histopathology. Presence of an ultrasound DWA was associated with more plaque hemosiderin (p = 0.0005) and inflammation (p = 0.019) on histopathology examination. The percent of plaque black area in any one component was associated with a higher score for macroscopic ulceration (p = 0.028). Ultrasound plaque characteristics (GSM, DWAs and black areas) represent histopathologic markers associated with plaque vulnerability. ClinicalTrials.gov identifier: NCT02476396. PMID- 27720281 TI - The predictive value of dendritic cells in early squamous cell carcinoma of the tongue. AB - OBJECTIVES: The aim of this study was to evaluate the relationship between dendritic cell density in early squamous cell carcinoma (SCC) of the tongue and patients' clinical outcome. METHODS: Representative samples of low-risk SCC of the tongue (T1-2,N0,M0) from a homogeneous group of 18 patients following local complete excision and elective selective neck dissection, were immunostained with antibodies against S100 and CD1a. Dendritic cell density was analyzed by outcome. RESULTS: Mean dendritic cell densities were 17 cells/HPF for tumoral S100 and CD1a counts, and 10 cells/HPF for peritumoral S100 and CD1a counts. Better disease-free survival was associated with low peritumoral S100- and CD1a- positive cell counts (p=0.006 and p=0.004, respectively), and with low tumoral S100- and CD1a- positive cell counts (p=0.037 and p=0.04, respectively). Lymphocytic response was decreased in tumors with high dendritic cell density (p=NS). There was no association of dendritic cell density with patient age, tumor size and depth of invasion. CONCLUSIONS: These results may suggest an association between dendritic cell accumulation and functional immunologic impairment.

PMID- 27720282 TI - [Clitoral reconstruction after female genital mutilation at CHU Yalgado of Ouagadougou, Burkina Faso. About 68 patients operated]. AB - OBJECTIVE: The objective of this survey was to assess the results of a new clitoral transposition technique in the obstetrics and gynecology department of CHUYO. MATERIALS AND METHOD: A cohort of 68 women victims of genital mutilation has received clitoral reconstruction by a new technique of transposition of the clitoris. They were operated and followed for 12 months in CHUYO gynecology ward in Ouagadougou. We evaluated the management of pain, anatomical aspect, functional and occurrence of complications. RESULTS: Anatomically have no new increase was within a neoclitoris, and a very satisfactory ratio of 100 % of women with clitoral massif visible in the 12th month assessment. Functionally, before clitoral reconstruction half of the women had mild pain or discomfort during sexual intercourse. However, clitoral reconstruction after the 6th month and 12th month this pain or mild discomfort were 3.18 % and 0 % respectively. In addition, we noted a sensitive neoclitoris in all women, after one year. Very few postoperative complications were observed in this series compared to previous series. CONCLUSION: These results are of interest in this new clitoral transposition technique in favor of women victims of genital mutilation.

AB - BACKGROUND: The release of the Center for Medicare and Medicaid Service's (CMS) latest quality measure, Severe Sepsis/Septic Shock Early Management Bundle (SEP 1), has intensified the long-standing debate over optimal care for severe sepsis and septic shock. Although the last decade of research has demonstrated the importance of comprehensive bundled care in conjunction with compliance mechanisms to reduce patient mortality, it is not clear that SEP-1 achieves this aim. The heterogeneous and often cryptic presentation of severe sepsis and septic shock, along with the multifaceted criteria for the definition of this clinical syndrome, pose a particular challenge for fitting requirements to this disease, and implementation could have unintended consequences. OBJECTIVE: Following a simulated reporting exercise, in which 50 charts underwent expert review, we aimed to detail the challenges of, and offer suggestions on how to rethink, measuring performance in severe sepsis and septic shock care. DISCUSSION: There were several challenges associated with the design and implementation of this measure. The ambiguous definition of severe sepsis and septic shock, prescriptive fluid volume requirements, rigid reassessment, and complex abstraction logic all raise significant concern. CONCLUSIONS: Although SEP-1 represents an important first step in requiring hospitals to improve outcomes for patients with severe sepsis and septic shock, the current approach must be revisited. The volume and complexity of the currently required SEP-1 reporting elements deserve serious consideration and revision before they are used as measures of accountability and tied to reimbursement. PMID- 27720288 TI - Variation in the Intensity of Care for Patients with Uncomplicated Renal Colic Presenting to U.S. Emergency Departments. AB - BACKGROUND: Renal colic results in > 1 million ED visits per year, yet there exists a gap in understanding how the majority of these visits, namely uncomplicated cases, are managed. OBJECTIVE: We assessed patient- and hospital level variation for emergency department (ED) management of uncomplicated kidney stones. METHODS: We identified ED visits from non-elderly adults (aged 19-79 years) with a primary diagnosis indicating renal stone or colic from the 2011 Nationwide Emergency Department Sample. Patients with additional diagnostic codes indicating infection, sepsis, and abdominal aortic aneurysm were excluded. We used sample-weighted logistic regression to determine the association between hospital admission and having a urologic procedure with patient and hospital characteristics. RESULTS: Of the 1,061,462 ED visits for uncomplicated kidney stones in 2011, 8.0% of visits resulted in admission and 6.3% resulted in an inpatient urologic procedure. Uninsured patients compared to Medicaid insured patients were less likely to be admitted or have an inpatient urologic procedure (odds ratio [OR] = 0.72; 95% confidence interval [CI] 0.65-0.81 and OR = 0.80; 95% CI 0.72-0.87, respectively). Private- and Medicare-insured patients compared to Medicaid-insured patients were more likely to have an inpatient urologic procedure (OR = 1.20; 95% CI 1.11-1.30 and OR = 1.14; 95% CI 1.04-1.25, respectively). CONCLUSIONS: For patients with uncomplicated renal colic, there is variation in the management associated with nonclinical factors, namely insurance. No consensus guidelines exist yet to address when to admit or utilize inpatient urologic procedures. PMID- 27720290 TI - Prognosis of Prolonged Intensive Care Unit Stay After Aortic Valve Replacement for Severe Aortic Stenosis in Octogenarians. AB - OBJECTIVES: Octogenarians considered for cardiac surgery encounter more complications than other patients. Postoperative complications raise the question of continuation of high-cost care for patients with limited life expectancy. Duration of hospitalization in intensive care after cardiac surgery may differ between octogenarians and other patients. The objectives were evaluating the mortality rate of octogenarians experiencing prolonged hospitalization in intensive care and defining the best cut-off for prolonged intensive care unit length of stay. DESIGN: A single-center observational study. SETTING: A postoperative surgical intensive care unit in a tertiary teaching hospital in Paris, France. PARTICIPANTS: All consecutive patients older than 80 years considered for aortic valve replacement for aortic stenosis were included. MEASUREMENTS AND MAIN RESULTS: Mortality rate was determined among patients experiencing prolonged stay in intensive care with organ failure and without organ failure. An ROC curve determined the optimal cut-off defining prolonged hospitalization in intensive care according to the occurrence of postoperative complications. Multivariate analysis determined risk factors for early death or prolonged intensive care stay. The optimal cut-off defining prolonged intensive care unit length of stay was 4 days. Low ventricular ejection fraction (odds ratio [OR] = 0.95; 95% confidence interval [CI] 0.96-0.83; p = 0.0016), coronary disease (OR = 2.34; 95% CI 1.19-4.85; p = 0.014), and need for catecholamine (OR = 2.79; 95% CI 1.33-5.88; p = 0.0068) were associated with eventful postoperative course. There was not a hospitalization duration beyond which the prognosis significantly worsened. CONCLUSIONS: Prolonged length of stay in ICU without organ failure is not associated with increased mortality. No specific duration of hospitalization in intensive care was associated with increased mortality. Continuation of care should be discussed on an individual basis. PMID- 27720291 TI - Impact of Milrinone Administration in Adult Cardiac Surgery Patients: Updated Meta-Analysis. AB - OBJECTIVE: To determine the effects of milrinone on short-term mortality in cardiac surgery patients with focus on the presence or absence of heterogeneity of the effect. DESIGN: A systematic review and meta-analysis. SETTING AND PARTICIPANTS: Five hundred thirty-seven adult cardiac surgery patients from 12 RCTs. INTERVENTIONS: Milrinone administration. MEASUREMENTS AND MAIN RESULTS: The authors conducted a systematic Medline and Pubmed search to assess the effect of milrinone on short-term mortality in adult cardiac surgery patients. Subanalysis was performed according to the timing for commencement of milrinone administration and the type of comparators. The primary outcome was any short term mortality. Overall analysis showed no difference in mortality rates in patients who received milrinone and patients who received comparators (odds ratio = 1.25, 95% CI 0.45-3.51, p = 0.67). In subanalysis for the timing to commence milrinone administration and the type of comparators, odds ratio for mortality varied from 0.19 (placebo as control drug, start of administration after cardiopulmonary bypass) to 2.58 (levosimendan as control drug, start of administration after cardiopulmonary bypass). CONCLUSIONS: Among RCTs to assess the effect of milrinone administration in adult cardiac surgery patients, there are wide variations of the odds ratios of administration of milrinone for short term mortality according to the comparators and the timing of administration. This fact may suggest that a simple pooling meta-analysis is not applicable for assessing the risk and benefit of milrinone administration in an adult cardiac surgery cohort.

AB - A number of new 3,7-disubstituted pyrazolo[3,4-c]pyridines have been designed and synthesized from suitable 2-aminopyridines. The antiproliferative activity of the derivatives was determined against the pancreatic MIA PaCa-2 and ovarian SCOV3 cancer cell-lines. IC50 values of the most promising analogue 46 lie in the submicromolar or low micromolar range. Furthermore, compound 46 shows similar inhibitory activities against DU145, A2058 and PC-3 cancer cells, blocks the cell cycle at the G0/G1 phase and induce apoptosis, as determined by the appearance of apoptotic nuclei.

AB - A focused N-substituted 3-(2-piperazin-1-yl-2-oxoethyl)-2-(pyridin-2-yl)iso indolin-1-ones small library was synthesized for modulation of GABA-A receptor function and compared to Zopiclone for the ability to increase GABA-activated chloride currents. All compounds were tested for their effects on GABA-activated chloride currents in rat cerebellar granule cells by use of the whole-cell patch clamp technique. Electrophysiological studies on cultured cerebellar granule cells revealed 3-[2-(4-methylpiperazin-1-yl)-2-oxoethyl]-2-(5-nitropyridin-2 yl)iso-indolin-1-one (Id) as a partial agonist displaying 34% increase of the 10MUM GABA evoked peak chloride currents, antagonized by flumazenil. Moreover, a second group of compounds, with bulky functional groups at N-4 position of piperazine, have shown inverse agonist effects. The simple synthetic procedure and the possibility of modulating the efficacy of this class of ligands through additional structural modifications pave the way for further development of new molecules as a novel class of compounds able to interfere with benzodiazepine receptors.

Interpretation of the results suggest different modes of action in antifungal activity for the two classes of compounds. PMID- 27720295 TI - Targeting the HSP60/10 chaperonin systems of Trypanosoma brucei as a strategy for treating African sleeping sickness. AB - Trypanosoma brucei are protozoan parasites that cause African sleeping sickness in humans (also known as Human African Trypanosomiasis-HAT). Without treatment, T. brucei infections are fatal. There is an urgent need for new therapeutic strategies as current drugs are toxic, have complex treatment regimens, and are becoming less effective owing to rising antibiotic resistance in parasites. We hypothesize that targeting the HSP60/10 chaperonin systems in T. brucei is a viable anti-trypanosomal strategy as parasites rely on these stress response elements for their development and survival. We recently discovered several hundred inhibitors of the prototypical HSP60/10 chaperonin system from Escherichia coli, termed GroEL/ES. One of the most potent GroEL/ES inhibitors we discovered was compound 1. While examining the PubChem database, we found that a related analog, 2e-p, exhibited cytotoxicity to Leishmania major promastigotes, which are trypanosomatids highly related to Trypanosoma brucei. Through initial counter-screening, we found that compounds 1 and 2e-p were also cytotoxic to Trypanosoma brucei parasites (EC50=7.9 and 3.1MUM, respectively). These encouraging initial results prompted us to develop a library of inhibitor analogs and examine their anti-parasitic potential in vitro. Of the 49 new chaperonin inhibitors developed, 39% exhibit greater cytotoxicity to T. brucei parasites than parent compound 1. While many analogs exhibit moderate cytotoxicity to human liver and kidney cells, we identified molecular substructures to pursue for further medicinal chemistry optimization to increase the therapeutic windows of this novel class of chaperonin-targeting anti-parasitic candidates. An intriguing finding from this study is that suramin, the first-line drug for treating early stage T. brucei infections, is also a potent inhibitor of GroEL/ES and HSP60/10 chaperonin systems.

AB - A series of novel pyrido[2',3':3,4] pyrazolo[1,5-a]pyrimidine derivatives 6-9 were prepared in single step starting from 3-amino-6-(trifluoromethyl)-1H pyrazolo[3,4-b]pyridine-5-carboxylate 5 on reaction with symmetrical and unsymmetrical aliphatic and aromatic 1,3-diketones/alpha,beta unsaturated ketones/alpha,beta unsaturated keto ethers under conventional method. All the final compounds 6a-c, 8a-b and 9a-l were screened for anticancer activity against five human cancer cell lines such as PC-3 (CRL-1435), MDA-MB-231 (HTB-26), Hep G2 (HB-8065), HeLa (CCL-2) and normal HUVEC (CRL-1730). Compounds 8a, 9f and 9k which showed promising anticancer activity have been identified. Further, the promising compounds (8a and 9f) were able to inhibit the human topoisomerase I (TopI) activity similar to that of camptothecin. PMID- 27720297 TI - Marek's disease herpesvirus vaccines integrate into chicken host chromosomes yet lack a virus-host phenotype associated with oncogenic transformation. AB - Marek's disease (MD) is a lymphotropic and oncogenic disease of chickens that can lead to death in susceptible and unvaccinated host birds. The causative pathogen, MD virus (MDV), a highly oncogenic alphaherpesvirus, integrates into host genome near the telomeres. MD occurrence is controlled across the globe by biosecurity, selective breeding for enhanced MD genetic resistance, and widespread vaccination of flocks using attenuated serotype 1 MDV or other serotypes. Despite over 40 years of usage, the specific mechanism(s) of MD vaccine-related immunity and anti tumor effects are not known. Here we investigated the cytogenetic interactions of commonly used MD vaccine strains of all three serotypes (HVT, SB-1, and Rispens) with the host to determine if all were equally capable of host genome integration. We also studied the dynamic profiles of chromosomal association and integration of the three vaccine strains, a first for MD vaccine research. Our cytogenetic data provide evidence that all three MD vaccine strains tested integrate in the chicken host genome as early as 1 day after vaccination similar to oncogenic strains. However, a specific, transformation-associated virus-host phenotype observed for oncogenic viruses is not established. Our results collectively provide an updated model of MD vaccine-host genome interaction and an improved understanding of the possible mechanisms of vaccinal immunity. Physical integration of the oncogenic MDV genome into host chromosomes along with cessation of viral replication appears to have joint signification in MDV's ability to induce oncogenic transformation. Whereas for MD vaccine serotypes, a sustained viral replication stage and lack of the chromosome-integrated only stage were shared traits during early infection.

AB - PURPOSE: To determine the isolated function of the pubofemoral ligament of the hip capsule and its contribution to hip stability in external/internal rotational motion during flexion greater than 30 degrees and abduction. METHODS: Thirteen hips from 7 fresh-frozen pelvis-to-toe cadavers were skeletonized from the lumbar spine to the distal femur with the capsular ligaments intact. Computed tomographic imaging was performed to ensure no occult pathological state existed, and assess bony anatomy. Specimens were placed on a surgical table in supine position with lower extremities resting on a custom-designed polyvinylchloride frame. Hip internal and external rotation was measured with the hip placed into a combination of the following motions: 30 degrees , 60 degrees , 110 degrees hip flexion and 0 degrees , 20 degrees , 40 degrees abduction. Testing positions were randomized. The pubofemoral ligament was released and measurements were repeated, followed by releasing the ligamentum teres. RESULTS: Analysis of the 2,106 measurements recorded demonstrates the pubofemoral ligament as a main controller of hip internal rotation during hip flexion beyond 30 degrees and abduction. Hip internal rotation was increased up to 438.9% (P < .001) when the pubofemoral ligament was released and 412.9% (P < .001) when both the pubofemoral and teres ligament were released, compared with the native state. CONCLUSIONS: The hypothesis of the pubofemoral ligament as one of the contributing factors of anterior inferior hip stability by controlling external rotation of the hip in flexion beyond 30 degrees and abduction was disproved. The pubofemoral ligament maintains a key function in limiting internal rotation in the position of increasing hip flexion beyond 30 degrees and abduction. This cadaveric study concludes previous attempts at understanding the anatomical and biomechanical function of the capsular ligaments and their role in hip stability. CLINICAL RELEVANCE: The present study contributes to the understanding of hip stability and biomechanical function of the pubofemoral ligament.

AB - PURPOSE: To compare the outcome of labral repair versus labral reconstruction in patients presenting to a single surgeon for revision hip arthroscopy following previous labral treatment. METHODS: Patients who underwent revision labral repair or labral reconstruction using iliotibial band allograft, after previous labral debridement or repair, between 2009 and 2013 were identified. Hips that underwent revision labral reconstruction were further stratified into 2 graft groups (freeze-dried vs frozen allograft). Exclusion criteria were age <16 years, previous open hip surgery, or previous labral reconstruction. Failure was defined by subsequent intra-articular hip surgery. RESULTS: 113 hips (15 repair, 98 reconstruction) met the inclusion criteria. Patients who underwent revision labral repair were younger than patients who underwent revision labral reconstruction (27.8 years vs 34.6 years; P = .02). Follow-up was obtained from 14 (93%) labral repairs at an average of 4.7 years postoperation (range: 2.0-6.0 years) and 90 (92%) labral reconstructions at an average of 2.4 years postoperation (range: 2.0-4.0 years). Seven of 14 (50%) labral repair hips failed compared with 11/90 (12%) labral reconstruction hips (P < .01). Six of 61 (10%) frozen allografts failed compared with 5/29 (17%) freeze-dried allografts (P = .32). Patients who underwent revision labral repair were 4.1 (95% confidence interval 1.9, 8.8) times more likely to fail than patients who underwent revision labral reconstruction. CONCLUSIONS: Patients who underwent revision labral repair following previous repair or debridement were 2.6 times more likely to fail than patients who underwent revision labral reconstruction, controlling for calendar time. In addition, revision labral reconstruction with frozen allograft had lower propensity of failure than freeze-dried allograft. However, there was no statistically significant difference in patient-reported outcome scores between the 2 groups. Based on these results, complete labral reconstruction with longer, nonsegmental graft led to a lower failure rate in this study population and can be considered for treatment of patients presenting for revision labral treatment.

PMID- 27720303 TI - Does the Hip Capsule Remain Closed After Hip Arthroscopy With Routine Capsular Closure for Femoroacetabular Impingement? A Magnetic Resonance Imaging Analysis in Symptomatic Postoperative Patients. AB - PURPOSE: The purpose of this study was to examine the hip capsule in a subset of symptomatic patients who underwent capsular closure during hip arthroscopy. METHODS: All patients undergoing primary hip arthroscopy for femoroacetabular impingement (FAI) with routine capsular closure between January 1, 2012, and December 31, 2015, were eligible. Only patients with unilateral surgery and a postoperative magnetic resonance imaging (MRI; ordered for persistent symptoms) were included. Four independent reviewers evaluated each hip capsule for thickness and the absence or presence of defects. RESULTS: During the study, 1,463 patients had hip arthroscopy for FAI with routine capsular closure, and 53 (3.6%) underwent a postoperative MRI. Fourteen of the 53 were excluded owing to revision status or additional procedures. The final study population included 39 patients (23 female patients and 16 male patients), with an average patient age of 31.7 +/- 11.4 years and an average body mass index of 23.3 +/- 2.9. There were 3 (7.5%) capsular defects, and the intraclass correlation coefficient (ICC) was 0.82. The operative hip capsule was significantly thicker in the zone of capsulotomy, and subsequent repair as compared with the unaffected, contralateral hip capsule (5.0 +/- 1.2 mm vs 4.6 +/- 1.4 mm; P = .02), ICC 0.83. Additionally, males had thicker hip capsules as compared with their female counterparts, on the operative side (5.4 +/- 1.1 mm vs 4.5 +/- 1.2 mm; P = .02) and the nonoperative side (4.8 +/- 1.6 mm vs 4.1 +/- 0.9 mm; P = .08). CONCLUSIONS: In a subset of symptomatic patients after hip arthroscopy for FAI, the majority (92.5%) of the repaired hip capsules remained closed at greater than 1 year of follow-up. The hip capsule adjacent to the capsulotomy and subsequent repair is thickened compared with the same location on the contralateral, nonoperative hip. Aside from gender, patient-related and FAI-related factors do not correlate with capsular thickness nor do they seem to correlate with the propensity to develop a capsular defect.

PMID- 27720307 TI - Self-organization in development, regeneration and organoids. AB - Self-organization of cells is a fundamental design principle in biology, yet the inherent non-linearity of self-organizing systems often poses significant challenges in deciphering the underlying mechanisms. Here, we discuss recent progress in this respect, focusing on examples from development, regeneration and organoid differentiation. Together, these three paradigms emphasize the active material properties of tissues that result from the functional coupling between individual cells as active units. Further, we discuss the challenge of obtaining reproducible outcomes on the basis of self-organizing systems, which development and regeneration, but not the current organoid culture protocols, achieve. PMID- 27720306 TI - Epigenetic regulation of pro-inflammatory cytokine secretion by sphingosine 1 phosphate (S1P) in acute lung injury: Role of S1P lyase. AB - Cellular level of sphingosine-1-phosphate (S1P), the simplest bioactive sphingolipid, is tightly regulated by its synthesis catalyzed by sphingosine kinases (SphKs) 1 & 2 and degradation mediated by S1P phosphatases, lipid phosphate phosphatases, and S1P lyase. The pleotropic actions of S1P are attributed to its unique inside-out (extracellular) signaling via G-protein coupled S1P1-5 receptors, and intracellular receptor independent signaling. Additionally, S1P generated in the nucleus by nuclear SphK2 modulates HDAC1/2 activity, regulates histone acetylation, and transcription of pro-inflammatory genes. Here, we present data on the role of S1P lyase mediated S1P signaling in regulating LPS-induced inflammation in lung endothelium. Blocking S1P lyase expression or activity attenuated LPS-induced histone acetylation and secretion of pro-inflammatory cytokines. Degradation of S1P by S1P lyase generates Delta2 hexadecenal and ethanolamine phosphate and the long-chain fatty aldehyde produced in the cytoplasmic compartment of the endothelial cell seems to modulate histone acetylation pattern, which is different from the nuclear SphK2/S1P signaling and inhibition of HDAC1/2. These in vitro studies suggest that S1P derived long-chain fatty aldehyde may be an epigenetic regulator of pro-inflammatory genes in sepsis induced lung inflammation. Trapping fatty aldehydes and other short chain aldehydes such as 4-hydroxynonenal derived from S1P degradation and lipid peroxidation, respectively by cell permeable agents such as phloretin or other aldehyde trapping agents may be useful in treating sepsis-induced lung inflammation via modulation of histone acetylation. . PMID- 27720309 TI - Role of uteroplacental and fetal Doppler in identifying fetal growth restriction at term. AB - Identification of the fetus at risk of adverse outcome at term is a challenge to both clinicians and researchers alike. Despite the fact that fetal growth restriction (FGR) is a known risk factor for stillbirth, at least two thirds of the stillbirth cases at term are not small for gestational age (SGA) - a commonly used proxy for FGR. However, the majority of SGA fetuses are constitutionally small babies and do not suffer from adverse perinatal outcome. The cerebroplacental ratio (CPR) is emerging as a marker of failure to reach growth potential at term. CPR is an independent predictor of intrapartum fetal distress, admission to the neonatal unit at term, stillbirth, perinatal death and neonatal morbidity. Raised uterine artery Doppler resistance in the third trimester is independently associated with significantly lower birthweight and CPR. The combination of the estimated fetal weight, CPR and uterine Doppler in the third trimester can identify the majority of fetuses at risk of stillbirth. PMID- 27720308 TI - Re-establishment of nucleosome occupancy during double-strand break repair in budding yeast. AB - Homologous recombination (HR) is an evolutionarily conserved pathway in eukaryotes that repairs a double-strand break (DSB) by copying homologous sequences from a sister chromatid, a homologous chromosome or an ectopic location. Recombination is challenged by the packaging of DNA into nucleosomes, which may impair the process at many steps, from resection of the DSB ends to the re-establishement of nucleosomes after repair. However, nucleosome dynamics during DSB repair have not been well described, primarily because of a lack of well-ordered nucleosomes around a DSB. We designed a system in budding yeast Saccharomyces cerevisiae to monitor nucleosome dynamics during repair of an HO endonuclease-induced DSB. Nucleosome occupancy around the break is lost following DSB formation, by 5'-3' resection of the DSB end. Soon after repair is complete, nucleosome occupancy is partially restored in a repair-dependent but cell cycle independent manner. Full re-establishment of nucleosome protection back to the level prior to DSB induction is achieved when the cell cycle resumes following repair. These findings may have implications to the mechanisms by which cells sense the completion of repair. PMID- 27720310 TI - Sensitivity of clinically relevant dosimetric parameters to contouring uncertainty in postimplant dosimetry of low-dose-rate prostate permanent seed brachytherapy. AB - PURPOSE: There is strong evidence relating postimplant dosimetry for low-dose rate prostate seed brachytherapy to local control rates. The delineation of the prostate on CT images, however, represents a challenge due to the lack of soft tissue contrast to identify the prostate borders. This study aims at quantifying the sensitivity of prostate V100 and D90 to contouring uncertainty as clinically relevant parameters for evaluation of target coverage in postimplant dosimetry. METHODS AND MATERIALS: CT images, postoperative plans, and contours of a cohort of patients (n = 43; low risk = 55.8%, intermediate risk = 39.5%, high risk = 4.7%), who had received prostate seed brachytherapy, were imported into MIM Symphony treatment planning system. The prostate contours in postimplant CT images were expanded or contracted uniformly in extents of +/-1.00 mm, +/-2.00 mm, +/-3.00 mm, +/-4.00 mm, and +/-5.00 mm. The values for V100 and D90 were extracted from dose-volume histograms for each contour and compared. RESULTS: Significant changes were observed in the values of D90 and V100 as well as the number of inacceptable plans for expansion or contraction of only few millimeters. Evaluation of a plan coverage based on D90 was found to be less sensitive to systematic contouring errors compared with V100. Number of plans incorrectly identified for lack or adequacy of coverage is lower using D90 compared with V100 for the same margin of error. CONCLUSIONS: Evaluation of a plan coverage based on V100 is too sensitive to systematic contouring errors of prostate. D90 increases the accuracy of CT-based postimplant quality assurance in identifying plans with insufficient coverage compared with V100. PMID- 27720311 TI - Predictive factors of rectal toxicity after permanent iodine-125 seed implantation: Prospective cohort study in 2339 patients. AB - PURPOSE: To evaluate the incidence and the associated factors of rectal toxicity in patients with prostate cancer undergoing permanent seed implantation (PI) with or without external beam radiation therapy (EBRT) in a nationwide prospective cohort study in Japan (J-POPS) during the first 2 years. METHODS AND MATERIALS: A total of 2,339 subjects were available for the analyses. Rectal toxicity was evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. RESULTS: The 3-year cumulative incidence for grade >=2 rectal toxicity was 2.88%, 1.76%, and 6.53% in all subjects, PI group and EBRT combination therapy group, respectively. On multivariate analysis, among all subjects, grade >=2 rectal toxicity was associated with rectal volumes receiving 100% of the prescribed dose (R100; p < 0.0001) and EBRT combination therapy (p = 0.0066). R100 in the PI group (p = 0.0254), and R100 (p = 0.0011) and interactive planning (p = 0.0267) in the EBRT combination therapy group were also associated with grade >=2 toxicity. The 3-year cumulative incidence of grade >=2 rectal toxicity was 3.80% and 1.37% for R100 >= 1 mL and R100 < 1 mL, respectively, in the PI group (p = 0.0068), and 14.09% and 5.52% for R100 >= 1 mL and R100 < 1 mL, respectively, in the EBRT combination therapy group (p = 0.0070). CONCLUSIONS: Rectal toxicity was relatively rare in this study compared with previous reports. For Japanese prostate cancer patients, R100 < 1 mL in both PI and EBRT combination therapy groups and interactive planning in EBRT combination therapy group may be effective in decreasing the incidence of rectal toxicity. PMID- 27720312 TI - The surgical management of patients with clinical stage T4 bladder cancer: A single institution experience. AB - INTRODUCTION: Patients with clinical T4 (cT4) bladder cancer (BCa) infrequently undergo radical cystectomy (RC). We investigated the reliability of preoperative clinical staging, perioperative and survival outcomes in patients treated with RC due to cT4a-b BCa disease at a single tertiary care institution. METHODS: The study relied on 917 BCa patients treated with RC and pelvic lymph node dissection (PLND) at a single institution between January 1995 and December 2012. We compared the accuracy of the clinical assessment with final pathology results. Moreover, we evaluated perioperative outcomes, complication rates and survival after surgery. RESULTS: The median follow-up was 62 months. Overall, 74 (8.1%) patients presented cT4 stage at preoperative evaluation. Conversely, a pathological T4 disease was confirmed only in 68.9% patients staged initially as cT4. No differences were recorded in complications, 30 days readmission or 30 days death rates between cT1-T3 vs. cT4a vs. cT4b (p > 0.1). At multivariable Cox regression analyses predicting cancer specific mortality, clinical T4 stage vs. clinical T1-2, clinical T3 stage vs. clinical T1-2 and age were predictors of worst survival after RC (all p < 0.04). CONCLUSIONS: We recorded poor concordance between preoperative imaging and pathology in cT4 patients. No differences in major perioperative outcomes and acceptable survival expectancies were reported in patients treated for cT4 disease. PMID- 27720313 TI - [Surgical complications of renal transplantation]. AB - OBJECTIVE: To report the nature, incidence, diagnosis and treatment options of surgical complications after renal transplantation. MATERIAL AND METHODS: Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov/) and Embase (http://www.embase.com/) database from 1960 to 2016 using the following keywords "fistula; lymphocele; stricture; thrombosis", in association with "renal transplantation" in Title/Abstract field. Articles were selected according to methods, language of publication and relevance. A total of 7618 articles were identified including specifically 981 for vascular complications, 1016 for urologic complications and 239 for lymphocele; after careful selection 190 publications were eligible for our review. RESULTS: Surgical complications occur in 1 to 30% of renal transplantations while being incompletely reported without consensual management. Angioplasty techniques led to a significant improvement of short- and long-term vascular complications outcome. Risk factors for transplant thrombosis are a right allotransplant, multiple renal arteries or vasculopathy in the donor, diabetes, arterial disease or thrombophilia in the recipient and hemodynamic changes during procedure. Urinary complications and lymphocele significantly impair overall outcome and recipients quality of life with no demonstrated impact on allotransplant survival. Immediate or salvage pelvi-ureterostomy is a main treatment option for ureteral strictures and fistula. CONCLUSION: Prevention of surgical complications following renal transplantation relies on careful allotransplant preparation and strict respect of surgical best practices. Increasing comorbidities in recipients as well as marginal donors are significant limits for the improvement of post-transplant surgical outcome. PMID- 27720314 TI - A pilot study of cognitive insight and structural covariance in first-episode psychosis. AB - Cognitive insight is described as a balance between one's self-reflectiveness (recognition and correction of dysfunctional reasoning), and self-certainty (overconfidence). Neuroimaging studies have linked the ventrolateral prefrontal cortex (VLPFC) to cognitive insight in people with psychosis. However, the relationship between cognitive insight and structural connectivity between the VLPFC and other brain areas is unknown. Here, we investigated the modulation of cognitive insight on structural covariance networks involving the VLPFC in a first-episode psychosis sample. Fifteen patients with a first-episode psychosis provided magnetic resonance (MR) scans and completed the Beck Cognitive Insight Scale (BCIS). MR scans were also available for 15 historical controls. Seed-based analysis of structural covariance was conducted using the Mapping Anatomical Correlations Across the Cerebral Cortex (MACACC) methodology, whereby Pearson correlation coefficients were extracted between seed regions in left and right VLPFC and cortical thickness across the brain. Structural covariance maps between groups were compared at each vertex. In first-episode subjects, we evaluated the modulation of BCIS scores on cortical covariance between VLPFC and every other vertex. Findings showed no significant group difference between first-episode psychosis subjects and controls in thickness covariance seeded from left or right VLPFC. However, in first-episode psychosis subjects, a positive association with self-certainty was found in networks seeded from both left and right VLPFC with thickness in medial frontal cortex and right pars triangularis. No significant associations were found for self-reflectiveness. These results suggest that self certainty, but not self-reflectiveness, positively modulated cortical covariance in a frontal network in patients with a first-episode psychosis. PMID- 27720315 TI - Environmental pollution and risk of psychotic disorders: A review of the science to date. AB - Environmental pollution is a global problem with diverse and substantial public health implications. Although many environmental (i.e., non-genetic) risk factors for schizophrenia and other psychotic disorders have been identified, there has been comparatively little research on pollution as a possible risk factor. This is despite the fact that gene-by-environment interactions and epigenetic mechanisms are now recognized as likely facets of the etiology of schizophrenia, and the fact that pollution could potentially mediate the association between urban birth/upbringing and elevated risk. We conducted a review of the literature to date in order to summarize and synthesize work in this area. We identified 13 research reports and 16 review articles. Based on the extant knowledge in this area and what is known about the pathophysiology of schizophrenia, it is feasible that exposure to xenobiotic heavy metals such as lead and cadmium, constituents of air pollution such as particulate matter and nitrogen and sulfur oxides, organic solvents, and other constituents of environmental pollution could be component causes. Further research-from the cellular to epidemiological levels-is clearly needed. If causation is proven, enhancements of policy intended to reduce human exposure to environmental pollution could reduce the burden of schizophrenia and possibly other mental illnesses. PMID- 27720316 TI - Temporal persistence of anomalous self-experience: A 5years follow-up. AB - BACKGROUND: The concept of self-disorders in schizophrenia has gained substantial interest and it has now been established empirically that self-disorders aggregate in schizophrenia-spectrum disorders but not in other mental disorders or in healthy controls. Yet, the issue of temporal persistence has not been addressed. AIM: The aim of this study is to examine the temporal persistence of self-disorders. METHODS: 96 first admission patients were thoroughly assessed for psychopathology including SD at baseline and again 5years later. We created a 25 item self-disorder scale which was used both at baseline and follow-up to assess self-disorders. The scale was a pre-cursor of the later published EASE-scale. Additionally, we examined the development of positive and negative syndromes and of the Global Assessment of Functioning (GAF). RESULTS: There was a high correlation between self-disorders at baseline and at follow-up, and the majority of the items in self-disorders scale showed equal proportions between baseline and follow-up. CONCLUSION: Self-disturbances showed a high level of persistence at 5-year follow-up. PMID- 27720317 TI - Developing professional habits of hand hygiene in intensive care settings: An action-research intervention. AB - OBJECTIVES: To explore perceptions and unconscious psychological processes underlying handwashing behaviours of intensive care nurses, to implement organisational innovations for improving hand hygiene in clinical practice. RESEARCH METHODOLOGY: An action-research intervention was performed in 2012 and 2013 in the intensive care unit of a public hospital in Italy, consisting of: structured interviews, semantic analysis, development and validation of a questionnaire, team discussion, project design and implementation. Five general workers, 16 staff nurses and 53 nurse students participated in the various stages. RESULTS: Social handwashing emerged as a structured and efficient habit, which follows automatically the pattern "cue/behaviour/gratification" when hands are perceived as "dirty". The perception of "dirt" starts unconsciously the process of social washing also in professional settings. Professional handwashing is perceived as goal-directed. The main concern identified is the fact that washing hands requires too much time to be performed in a setting of urgency. These findings addressed participants to develop a professional "habit-directed" hand hygiene procedure, to be implemented at beginning of workshifts. CONCLUSIONS: Handwashing is a ritualistic behaviour driven by deep and unconscious patterns, and social habits affect professional practice. Creating professional habits of hand hygiene could be a key solution to improve compliance in intensive care settings. PMID- 27720318 TI - Heterogeneous histomorphology, yet homogeneous vascular smooth muscle cell dedifferentiation, characterize human aneurysm disease. AB - OBJECTIVE: Abdominal aortic aneurysm (AAA) is a frequent, potentially life threatening, disease that can only be treated by surgical means such as open surgery or endovascular repair. No alternative treatment is currently available, and despite expanding knowledge about the pathomechanism, clinical trials on medical aneurysm abrogation have led to inconclusive results. The heterogeneity of human AAA based on histologic examination is thereby generally neglected. In this study we aimed to further elucidate the role of these differences in aneurysm disease. METHODS: Tissue samples from AAA and popliteal artery aneurysm patients were examined by histomorphologic analysis, immunohistochemistry, Western blot, and polymerase chain reaction. The results were correlated with clinical data such as aneurysm diameter and laboratory results. RESULTS: The morphology of human AAA vessel wall probes varies tremendously based on the grade of inflammation. This correlates with increasing intima/media thickness and upregulation of the vascular endothelial growth factor cascade but not with any clinical parameter or the aneurysm diameter. The phenotypic switch of vascular smooth muscle cells occurred regardless of the inflammatory state and expressional changes of the transcription factors Kruppel-like factor-4 and transforming growth factor-beta lead to differential protein localization in aneurysmal compared with control arteries. These changes were in similar manner also observed in samples from popliteal artery aneurysms, which, however, showed a more homogenous phenotype. CONCLUSIONS: Heterogeneity of AAA vessel walls based on inflammatory morphology does not correlate with AAA diameter yet harbors specific implications for basic research and possible aneurysm detection. PMID- 27720319 TI - A multicenter experience with infected abdominal aortic endograft explantation. AB - OBJECTIVE: Endovascular aneurysm repair (EVAR) is widely used with excellent results, but its infectious complications can be devastating. In this paper, we report a multicenter experience with infected EVAR, symptoms, and options for explantation and their outcome. METHODS: We have reviewed all consecutive endograft explants for infection at 11 French university centers following EVAR, defined as index EVAR, from 1998 to 2015. Diagnosis of infected aortic endograft was made on the basis of clinical findings, cultures, imaging studies, and intraoperative findings. RESULTS: Thirty-three patients with an infected aortic endograft were identified. In this group, at index EVAR, six patients (18%) presented with a groin or psoas infection and six patients (18%) presented with a general infection, including catheter-related infection (n = 3), prostatitis (n = 1), cholecystitis (n = 1), and pneumonia (n = 1). After index EVAR, eight patients underwent successful inferior mesenteric artery embolization for a type II endoleak within 6 months of index EVAR and one patient received an additional stent for a type Ib endoleak 1 week after index EVAR. Median time between the first clinical signs of infection and endograft explantation was 30 days (range, 1 day to 2.2 years). The most common presenting characteristics were pain and fever in 21 patients (64%) and fever alone in 8 patients (24%). Suprarenal fixation was present in 20 of 33 endografts (60%). All patients underwent endograft explantation, with bowel resection in 12 patients (36%) presenting with an endograft-enteric fistula. Methods of reconstruction were graft placement in situ in 30 patients and extra-anatomic bypass in 3 patients. In situ conduits were aortic cryopreserved allografts in 23, polyester silver graft in 5, and autogenous femoral vein in 2. Microbiology specimens obtained from the endograft and the aneurysm were positive in 24 patients (74%). Gram-positive organisms were the most commonly found in 18 patients (55%). Early mortality (30 days or in the hospital) was 39% (n = 13) in relation to graft blowout (n = 3), multiple organ failure (n = 6), colon necrosis (n = 3), and peripheral embolism (n = 1). At 1 year, the rates of patient survival, graft-related complications, and reinfection were 44%, 10%, and 5%, respectively. CONCLUSIONS: Abdominal aortic endograft explantation for infection is high risk and associated with graft-enteric fistula in one-third of the cases. Larger multicenter studies are needed to better understand the risk factors and to improve preventive measures at index EVAR and during follow-up. PMID- 27720320 TI - Description of a risk predictive model of 30-day postoperative mortality after elective abdominal aortic aneurysm repair. AB - OBJECTIVE: Despite vast improvement in the field of vascular surgery, elective abdominal aortic aneurysm (AAA) repair still leads to perioperative death. Patients with asymptomatic AAAs, therefore, would benefit from an individual risk assessment to help with decisions regarding operative intervention. The purpose of this study was to describe such a 30-day postoperative (POD) risk prediction model using American College of Surgeons National Surgical Quality Improvement Project (NSQIP) data. METHODS: The NSQIP database (2005-2011) was queried for patients undergoing elective AAA repair using open or endovascular techniques. Clinical variables and known predictors of mortality were included in a full prediction model. These variables included procedure type, patient's age, functional dependence and comorbidities, and surgeon's specialty. Backward elimination with alpha-level of 0.2 was used to construct a parsimonious model. Model discrimination was evaluated in equally sized risk quintiles. RESULTS: The overall mortality rate for 18,917 elective AAA patients was 1.7%. In this model, surgeon's specialty was not predictive of POD. The most significant factors affecting POD included open repair (odds ratio [OR], 2.712; 95% confidence interval [CI], 2.119-3.469; P < .001), age >70 (OR, 2.243; 95% CI, 1.695-3.033; P < .001), functional dependency (OR, 2.290; 95% CI, 1.442-3.637; P < .001), creatinine above 2.0 mg/dL (OR, 2.1; 95% CI, 1.403-3.142; P < .001) and low hematocrit levels (OR, 2.157; 95% CI, 1.365-3.408; P = .001).The discriminating ability of the NSQIP model was reasonable (C-statistic = 0.751) and corrected to 0.736 after internal validation. The NSQIP model performed well predicting mortality among risk-group quintiles. CONCLUSIONS: The NSQIP risk prediction model is a robust vehicle to predict POD among patient undergoing elective AAA repair. This model can be used for risk stratification of patients undergoing elective AAA repair. PMID- 27720321 TI - Continuous alternating inhaled antibiotic therapy in CF: A single center retrospective analysis. AB - INTRODUCTION: The efficacy of inhaled antibiotics to treat chronic Pseudomonas aeruginosa pulmonary infection in patients with cystic fibrosis (CF) has been well established. Few data are available on the value of continuous alternating inhaled antibiotic therapy (CAIT), a strategy increasingly used in the management of CF. OBJECTIVE: To investigate the effect of CAIT on clinical outcome in adult CF patients treated at the University Hospital Leuven. METHODS: Patients with a documented CF diagnosis who received inhaled antibiotics between March 2010 and January 2015 were retrospectively evaluated. In patients receiving CAIT patient characteristics, recorded spirometry data and number of IV antibiotic days were collected retrospectively at fixed time intervals, from 6months before to one year after the start of the 2nd inhaled antibiotic. For patients on inhaled antibiotic monotherapy (IAMT), the same data were obtained at similar intervals during the study period. RESULTS: A total of 49 of 89 patients using chronic inhaled antibiotic therapy received CAIT. Patients receiving CAIT had a lower baseline FEV1 and were more likely to be homozygous for F508del compared to patients receiving IAMT. FEV1 deteriorated on average by a factor of 0.904 per year (95% CI: 0.851-0.960) prior to the start of CAIT. The initiation of CAIT was associated with an average improvement in FEV1 by a factor of 1.148 per year (95% CI: 1.068-1.236, p=0.0002). The analysis of specific types of antibiotics revealed evidence of positive effects of adding COLI to TOBI and COLI to AZLI. We found no effect of the initiation of CAIT on the number of IV antibiotic days (p=0.80). CONCLUSION: CF patients with more advanced lung disease are more likely to receive CAIT. In this patient group, CAIT was associated with a significant improvement in FEV1. Further data are warranted to identify the value of CAIT. PMID- 27720322 TI - RE: "Low back pain misdiagnosis or missed diagnosis: Core principles" (Monie AP, Fazey PJ, Singer KP. Manual Therapy 22 (2016) 68-71). PMID- 27720323 TI - Relationship between time to treatment and mortality among patients undergoing primary percutaneous coronary intervention according to Korea Acute Myocardial Infarction Registry. AB - BACKGROUND: Despite large reductions in door-to-balloon times over the period, several studies from regional and national data showed that annual mortality rates were not decreased among patients who underwent primary percutaneous coronary intervention (PCI). However, these studies mostly focused on door-to balloon time, and there was no consideration of total ischemic time in a trend of mortality. The aim of this study was to assess the annual trend between time to treatment and 1-month mortality among patients undergoing primary PCI. METHODS AND RESULTS: The study population consisted of 8040 patients who underwent primary PCI at hospitals participating in the nationwide prospective Korea Acute Myocardial Infarction Registry (KAMIR) between January 2008 and December 2011. The primary end point of this study was 1-month all-cause mortality, and time to treatment (door-to-balloon time, symptom-to-balloon time). One-month death occurred in 452 patients (5.6%) from 2008 to 2011. Additional reductions in door to-balloon time were not translated into parallel reductions in mortality rate and total ischemic time. After adjustment using clinical risk, shorter total ischemic time was an independent predictor of 1-month mortality [adjusted odds ratio (OR) 0.78, 95% confidential interval (CI) 0.62-0.99, p=0.04]. Total ischemic time could be reduced by using emergency medical services. CONCLUSION: Despite improvements in door-to-balloon time, no parallel reductions in mortality rate and total ischemic time were observed. Total ischemic time was associated with mortality. The present study suggests that additional efforts are needed to shorten total ischemic time including patient and pre-hospital systemic delay for better prognosis after primary PCI.

AB - A series of 1,4-diazabicyclo[2.2.2]octane derivatives differing by linker moiety was evaluated for activity against several strains of both Gram-positive and Gram negative bacteria including drug-resistant strains, one strain of fungus and influenza virus A/Puerto Rico/8/34 (H1N1). All compounds exhibited high antibacterial activity against all bacteria except Proteus vulgaris. The minimum inhibitory concentrations (MICs) of compound 1c with an o-phenylenebismethyl linker and compound 1e with a propylene aliphatic linker were found to be low and were comparable or better to the reference drug ciprofloxacin for Pseudomonas aeruginosa and Staphylococcus aureus. Additionally, a time-kill assay was performed to examine the bactericidal kinetics. Compounds 1c and 1e displayed rapid killing effects against St. aureus and Ps. aeruginosa after 2h. Furthermore, compounds 1a-c with aromatic linkers and compound 1e showed the highest antiviral activity. PMID- 27720325 TI - Novel approach of fragment-based lead discovery applied to renin inhibitors. AB - A novel approach was conducted for fragment-based lead discovery and applied to renin inhibitors. The biochemical screening of a fragment library against renin provided the hit fragment which showed a characteristic interaction pattern with the target protein. The hit fragment bound only to the S1, S3, and S3SP (S3 subpocket) sites without any interactions with the catalytic aspartate residues (Asp32 and Asp215 (pepsin numbering)). Prior to making chemical modifications to the hit fragment, we first identified its essential binding sites by utilizing the hit fragment's substructures. Second, we created a new and smaller scaffold, which better occupied the identified essential S3 and S3SP sites, by utilizing library synthesis with high-throughput chemistry. We then revisited the S1 site and efficiently explored a good building block attaching to the scaffold with library synthesis. In the library syntheses, the binding modes of each pivotal compound were determined and confirmed by X-ray crystallography and the library was strategically designed by structure-based computational approach not only to obtain a more active compound but also to obtain informative Structure Activity Relationship (SAR). As a result, we obtained a lead compound offering synthetic accessibility as well as the improved in vitro ADMET profiles. The fragments and compounds possessing a characteristic interaction pattern provided new structural insights into renin's active site and the potential to create a new generation of renin inhibitors. In addition, we demonstrated our FBDD strategy integrating highly sensitive biochemical assay, X-ray crystallography, and high-throughput synthesis and in silico library design aimed at fragment morphing at the initial stage was effective to elucidate a pocket profile and a promising lead compound. PMID- 27720328 TI - Multitarget-directed oxoisoaporphine derivatives: Anti-acetylcholinesterase, anti beta-amyloid aggregation and enhanced autophagy activity against Alzheimer's disease. AB - A series of 8- and 11-substituted oxoisoaporphine derivatives have been designed, synthesized, and tested for their ability to inhibit cholinesterase (ChE) in vitro and in vivo, and self-induced beta-amyloid (Abeta) aggregation. Their autophagy activity and blood-brain barrier (BBB) permeability were also assessed. The new derivatives exhibited high AChE inhibitory activity in vivo and in intro. Over half the derivatives exhibited a significant in vitro inhibitory activity toward the self-induced Abeta aggregation. While, treatment of SH-SY5Y cells overexpressing the Swedish mutant form of human beta-amyloid precursor protein (APPsw) with derivatives was associated with significant reduction of Abeta secretion levels. Moreover, one-third of the synthetic compounds were predicted to be able to cross the BBB to reach their targets in the central nervous system (CNS) according to a parallel artificial membrane permeation assay for BBB. Compounds 5b and 6b were chosen for assessing their autophagy activity. The fluorescence intensity of the BC12921 was decreased significantly after treatment with compounds. The result encourages us to study such compounds thoroughly and systematically. PMID- 27720327 TI - Design and synthesis of purine analogues as highly specific ligands for FcyB, a ubiquitous fungal nucleobase transporter. AB - In the course of our study on fungal purine transporters, a number of new 3 deazapurine analogues have been rationally designed, based on the interaction of purine substrates with the Aspergillus nidulans FcyB carrier, and synthesized following an effective synthetic procedure. Certain derivatives have been found to specifically inhibit FcyB-mediated [3H]-adenine uptake. Molecular simulations have been performed, suggesting that all active compounds interact with FcyB through the formation of hydrogen bonds with Asn163, while the insertion of hydrophobic fragments at position 9 and N6 of 3-deazaadenine enhanced the inhibition. PMID- 27720326 TI - Exploration of bivalent ligands targeting putative mu opioid receptor and chemokine receptor CCR5 dimerization. AB - Modern antiretroviral therapies have provided HIV-1 infected patients longer lifespans and better quality of life. However, several neurological complications are now being seen in these patients due to HIV-1 associated injury of neurons by infected microglia and astrocytes. In addition, these effects can be further exacerbated with opiate use and abuse. One possible mechanism for such potentiation effects of opiates is the interaction of the mu opioid receptor (MOR) with the chemokine receptor CCR5 (CCR5), a known HIV-1 co-receptor, to form MOR-CCR5 heterodimer. In an attempt to understand this putative interaction and its relevance to neuroAIDS, we designed and synthesized a series of bivalent ligands targeting the putative CCR5-MOR heterodimer. To understand how these bivalent ligands may interact with the heterodimer, biological studies including calcium mobilization inhibition, binding affinity, HIV-1 invasion, and cell fusion assays were applied. In particular, HIV-1 infection assays using human peripheral blood mononuclear cells, macrophages, and astrocytes revealed a notable synergy in activity for one particular bivalent ligand. Further, a molecular model of the putative CCR5-MOR heterodimer was constructed, docked with the bivalent ligand, and molecular dynamics simulations of the complex was performed in a membrane-water system to help understand the biological observation.

When pumping is stopped in a closed mine, the process of flooding should be anticipated in order to avoid environmentally undesirable or unexpected mine water discharges at the surface, particularly in populated areas. The Candin Fondon mining reservoir in Asturias (NW Spain) has an estimated void volume of 8 million m3 and some urban areas are susceptible to be flooded if the water is freely released from the lowest mine adit/pithead. A conceptual model of this reservoir was undertaken and the flooding process was numerically modelled in order to estimate the time that the flooding would take. Additionally, the maximum safe height for the filling of the reservoir is discussed. PMID- 27720331 TI - Thermodynamic parameters for adsorption equilibrium of heavy metals and dyes from wastewaters: Research updated. AB - The standard Gibbs free energy, enthalpy and entropy change data for adsorption equilibrium reported in biosorption literature during January 2013-May2016 were listed. Since the studied biosorption systems are all near-equilibrium processes, the enthalpy and entropy change data evaluated by fitting temperature-dependent free energy data using van Hoff's equation reveal a compensation artifact. Additional confusion is introduced with arbitrarily chosen adsorbate concentration unit in bulk solution that added free energy change of mixing into the reported free energy and enthalpy change data. Different standard states may be chosen for properly describing biosorption processes; however, this makes the general comparison between data from different systems inappropriate. No conclusion should be drawn based on unjustified thermodynamic parameters reported in biosorption studies. PMID- 27720332 TI - Neuronal SOCE: Myth or Reality? AB - Store-operated Ca2+ entry (SOCE) is the primary Ca2+ influx pathway in non excitable cells. Long thought to be absent in nerve cells, neuronal SOCE is gaining popularity. We argue here that the evidence for SOCE in neurons remains contentious, mostly because SOCE imaging assays are inadequate in these cells. PMID- 27720333 TI - Evaluation of a refill synchronization program in two community pharmacies. AB - OBJECTIVES: To describe medication adherence by the proportion of days covered before and after enrollment in a refill synchronization program. METHODS: We conducted a retrospective analysis of medication adherence in 2 pharmacies offering a refill synchronization program. The study population consisted of individuals who received 2 or more medications from any of 15 predefined medication classes within 6 months of enrollment in the synchronization program. Medication adherence and refill consolidation were measured over 6 months before and after enrollment. Optimal adherence was defined as proportion of days covered >=80%. RESULTS: Among 109 patients who enrolled in the program between 2009 and 2014, 68 were included in a pre-post analysis of medication adherence. In the preenrollment period, optimal adherence was observed in 85% (217/254) of the medications taken by the 68 patients, increasing to 93% (237/254) in the postenrollment period (P <0.01). In addition, the percentage maintaining optimal adherence to all of their medications increased significantly from 60% (n = 41) to 83% (n = 57; P <0.01). CONCLUSION: Among a small group of patients who voluntarily participated in refill synchronization programs, high levels of medication adherence were observed in the preenrollment period. These results combined with previous studies suggest that voluntary participants of these programs are at a low risk for nonadherence; therefore, current estimates of benefit from refill synchronization programs may be overestimated. PMID- 27720335 TI - Inattentional blindness and failures to rescue the deteriorating patient in critical care, emergency and perioperative settings: Four case scenarios. AB - BACKGROUND: Failure to identify and respond to clinical deterioration is an important measure of patient safety, hospital performance and quality of care. Although studies have identified the role of patient, system and human factors in failure to rescue events, the role of 'inattentional blindness' as a possible contributing factor has been overlooked. OBJECTIVES: To explore the nature and possible patient safety implications of inattentional blindness in critical care, emergency and perioperative nursing contexts. METHODS: Analysis of four case scenarios drawn from a naturalistic inquiry investigating how nurses identify and manage gaps (discontinuities) in care. Data were collected via in-depth interviews from a purposeful sample of 71 nurses, of which 20 were critical care nurses, 19 were emergency nurses and 16 were perioperative nurses. Case scenarios were identified, selected and analysed using inattentional blindness as an interpretive frame. RESULTS: The four case scenarios presented here suggest that failures to recognise and act upon patient observations suggestive of clinical deterioration could be explained by inattentional blindness. In all but one of the cases reported, vital signs were measured and recorded on a regular basis. However, teams of nurses and doctors failed to 'see' the early signs of clinical deterioration. The high-stress, high-complexity nature of the clinical settings in which these cases occurred coupled with high cognitive workload, noise and frequent interruptions create the conditions for inattentional blindness. CONCLUSIONS: The case scenarios considered in this report raise the possibility that inattentional blindness is a salient but overlooked human factor in failure to rescue events across the critical care spectrum. Further comparative cross disciplinary research is warranted to enable a better understanding of the nature and possible patient safety implications of inattentional blindness in critical care nursing contexts. PMID- 27720334 TI - Extracellular Vesicle Biogenesis in Helminths: More than One Route to the Surface? AB - The recent discovery that parasites release extracellular vesicles (EVs) that can transfer a range of effector molecules to host cells has made us re-think our understanding of the host-parasite interface. In this opinion article we consider how recent proteomics and transcriptomics studies, together with ultrastructural observations, suggest that more than one mechanism of EV biogenesis can occur in helminths. We propose that distinct EV subtypes have roles in immune modulation and repair of drug-induced damage, and put forward the case for targeting EV biogenesis pathways to achieve parasite control. In doing so we raise a number of outstanding research questions that must be addressed before this can happen. PMID- 27720336 TI - Assessment of accessory canals of the canalis sinuosus: a study of 1000 cone beam computed tomography examinations. AB - The aim of this study was to verify the presence, spatial location, and calibre of the accessory canals (AC) of the canalis sinuosus by cone beam computed tomography, and their relationship to the anterior maxilla. This retrospective analysis included the scans of 1000 subjects. Parameters registered were sex, age, number of AC, presence or absence of AC with a diameter <1.0mm, AC diameter (only for AC with a diameter >1.0mm), and AC location in relation to the adjacent teeth. Males showed a statistically higher frequency of AC than females. The difference in age distribution was not statistically significant. Twenty percent of all AC presented a diameter of a least 1.0mm. The end of the AC trajectory was most frequently located palatal to the anterior maxillary teeth. All relationships analyzed here were very weak (age vs. number of AC, age vs. AC diameter, number of AC vs. sex). Overall, the results of this study showed that AC of the canalis sinuosus are a common anatomical structure in the anterior maxilla, regardless of age and sex. PMID- 27720337 TI - A mathematical method for precisely calculating the radiographic angles of the cup after total hip arthroplasty. AB - We established a mathematical method to precisely calculate the radiographic anteversion (RA) and radiographic inclination (RI) angles of the acetabular cup based on anterior-posterior (AP) pelvic radiographs after total hip arthroplasty. Using Mathematica software, a mathematical model for an oblique cone was established to simulate how AP pelvic radiographs are obtained and to address the relationship between the two-dimensional and three-dimensional geometry of the opening circle of the cup. In this model, the vertex was the X-ray beam source, and the generatrix was the ellipse in radiographs projected from the opening circle of the acetabular cup. Using this model, we established a series of mathematical formulas to reveal the differences between the true RA and RI cup angles and the measurements results achieved using traditional methods and AP pelvic radiographs and to precisely calculate the RA and RI cup angles based on post-operative AP pelvic radiographs. Statistical analysis indicated that traditional methods should be used with caution if traditional measurements methods are used to calculate the RA and RI cup angles with AP pelvic radiograph. The entire calculation process could be performed by an orthopedic surgeon with mathematical knowledge of basic matrix and vector equations. PMID- 27720339 TI - Acculturation and Dental Service Use Among Asian Immigrants in the U.S. AB - INTRODUCTION: The objective of this study was to assess dental service utilization across different Asian immigrant groups and to examine the relationship between acculturation and dental service utilization among Asian immigrants in the U.S. METHODS: Data were from the 2013 and 2014 National Health Interview Surveys. Multiple logistic regression models were used to examine the association between acculturation and having a dental visit in the previous 12 months, controlling for predisposing, enabling, and need factors. Acculturation was measured by length of stay in the U.S., English language proficiency, and U.S. citizenship. The sample was 2,948 adult Asian immigrants who were dentate. Data were analyzed in 2016. RESULTS: Dental service utilization varied across Asian immigrant groups. High English proficiency and longer length of stay were significantly associated with having a dental visit (p<0.05). In the final model, after adding enabling factors-dental insurance and family income levels-length of stay in the U.S. (>=5 years) remained significant, whereas English language proficiency was not a significant correlate of having a dental visit. CONCLUSIONS: Length of stay in the U.S. is a significant factor affecting dental service utilization among Asian immigrants. PMID- 27720338 TI - Built Environment and Depression in Low-Income African Americans and Whites. AB - INTRODUCTION: Urban environments are associated with a higher risk of adverse mental health outcomes; however, it is unclear which specific components of the urban environment drive these associations. METHODS: Using data collected in 2002 2009 from 73,225 low-income, racially diverse individuals across the Southeastern U.S., analyses evaluated the cross-sectional relationship between a walkability index and depression. Walkability was calculated from population density, street connectivity, and destination count in the 1,200-meter area around participants' homes, and depression was measured using the Center for Epidemiologic Studies Depression Scale for depression symptomatology and questionnaire responses regarding doctor-diagnosed depression and antidepressant use. Data were analyzed in 2015. RESULTS: Participants living in neighborhoods with the highest walkability index had 6% higher odds of moderate or greater depression symptoms (score >=15, 95% CI=0.99, 1.14), 28% higher odds of doctor-diagnosed depression (95% CI=1.20, 1.36), and 16% higher odds of current antidepressant use (95% CI=1.08, 1.25), compared with those in the lowest walkability index. Higher walkability was associated with higher odds of depression symptoms in the most deprived neighborhoods only, whereas walkability was associated with lower odds of depression symptoms in the least deprived neighborhoods. CONCLUSIONS: Living in a more walkable neighborhood was associated with modestly higher levels of doctor-diagnosed depression and antidepressant use, and walkability was associated with greater depression symptoms in neighborhoods with higher deprivation. Although dense urban environments may provide opportunities for physical activity, they may also increase exposure to noise, air pollution, and social stressors that could increase levels of depression. PMID- 27720340 TI - A Systematic Review of Interventions to Increase Stair Use. AB - CONTEXT: Stair climbing is an accessible activity that can be incorporated into one's daily lifestyle to increase physical activity levels and provide health benefits. This review summarizes the effectiveness of stair interventions and explores key differences that may influence intervention effectiveness. EVIDENCE ACQUISITION: Interventions to increase stair use published from January 1990 to July 2015 were identified in PubMed, Sport Discus, Web of Science, Environment Complete, CINAHL, Trial Register of Promoting Health Interventions, Embase, Scopus, and PsycINFO. Eligibility criteria included original studies, published in peer-reviewed journals, targeting adult samples, and clearly describing intervention design and results. Studies were also required to measure the use of stairs compared with an elevator, escalator, or moving stairway at baseline and during at least one timepoint when the intervention was in effect. Studies were required to provide data to determine if the intervention resulted in significant changes in stair use/climbing. EVIDENCE SYNTHESIS: The search results yielded 2,136 articles in total; 54 articles met the criteria, which resulted in a final sample of 67 studies included in the analyses. Interventions settings included public sites (75%), worksites (21%), or a combination of both (4%). For Phase 1 results, 72% of studies reported significant improvements in stair use (n=10 of 14) and stair climbing (n=38 of 53). CONCLUSIONS: Evidence from the review demonstrates support for the effectiveness of interventions to increase stair use and stair climbing. Although evidence supports the effectiveness of stair interventions in public settings, less support is provided for worksites. PMID- 27720341 TI - Non-Cognitive Personality Assessment and Risk of Injuries Among Army Trainees. AB - INTRODUCTION: Low levels of pre-accession physical fitness and activity are risk factors for stress fractures and other overuse musculoskeletal injuries among military trainees. One dimension in the Tailored Adaptive Personality Assessment System (TAPAS), a non-cognitive personality test given to Army applicants, specifically assesses propensity to engage in physical activity. This dimension may serve as a surrogate measure for activity or fitness. The study examines the associations between TAPAS dimension scores and risk of musculoskeletal injuries. METHODS: Fifteen TAPAS dimension scores for 15,082 U.S. Army trainees entering military service in 2010 were provided by the U.S. Army Research Institute for Social and Behavioral Sciences. During 2013-2015, the associations between TAPAS dimension scores (as a continuous variable) and injuries in the first 6 months of service were evaluated using logistic regression, with the measure of association being the OR. RESULTS: The TAPAS physical conditioning dimension was associated with musculoskeletal injuries and stress fractures among both men (musculoskeletal injury, OR=0.83, 95% CI=0.79, 0.86; stress fracture, OR=0.68, 95% CI=0.57, 0.80) and women (musculoskeletal injury, OR=0.77, 95% CI=0.70, 0.85; stress fracture, OR=0.60, 95% CI=0.43, 082). No other dimensions were both significantly and consistently associated with either injury. CONCLUSIONS: The TAPAS physical conditioning dimension is a strong predictor of musculoskeletal injury and stress fracture among male and female U.S. Army trainees, and may serve as a pre-accession screen for self-reported physical activity.

PMID- 27720342 TI - National and State-Specific Shingles Vaccination Among Adults Aged >=60 Years. AB - INTRODUCTION: Shingles (herpes zoster) causes substantial morbidity, especially among older adults. The shingles vaccine has been recommended for people aged >=60 years since 2006. This study assessed recent shingles vaccination at national and state levels among adults aged >=60 years. METHODS: The 2014 Behavioral Risk Factor Surveillance System data were analyzed in 2015 to assess shingles vaccination coverage among adults aged >=60 years at national and state levels. Multivariable logistic regression and predictive marginal models identified factors independently associated with vaccination. RESULTS: Shingles vaccination coverage among adults aged >=60 years was 31.8% (95% CI=31.4%, 32.2%). Among states, shingles vaccination coverage ranged from 17.8% (95% CI=15.8%, 20.0%) in Mississippi to 46.6% (95% CI=44.3%, 48.8%) in Vermont, with a median of 33.3%. Coverage was <25% in four states and >40% in nine states. For all states, coverage was significantly higher among non-Hispanic whites compared with non-white races except for Oregon, with coverage differences ranging from 33.2% in the District of Columbia to 0.9% in Oregon and a median of -16.0%. Characteristics independently associated with vaccination were age, race/ethnicity, sex, education, employment status, household income, region, perceived health status, health insurance status, personal healthcare provider, routine checkup status, and whether reporting that cost was a barrier to seeing a doctor. CONCLUSIONS: Coverage varied dramatically by state. State-level comparisons may aid in designing tailored intervention programs through sharing of best practices. Strategies are needed to mitigate financial barriers for both provider and patients, improve awareness, and increase provider recommendation of the vaccine. PMID- 27720344 TI - Long-term outcomes of hepatitis B virus-related cirrhosis treated with nucleos(t)ide analogs. AB - BACKGROUND/PURPOSE: This study aimed to evaluate the outcomes of chronic hepatitis B patients with cirrhosis who received long-term nucleos(t)ide analog therapy. METHODS: A total of 546 consecutive cirrhotic patients treated with entecavir (n = 359), telbivudine (n = 104), or tenofovir (n = 83) for chronic hepatitis B were enrolled. The incidence of hepatocellular carcinoma (HCC) and overall survival were evaluated. RESULTS: During a median follow-up of 39 months, 56 (10.3%) patients developed HCC and 14 (2.6%) patients died. These outcomes were not associated with different antiviral use. Cox proportional hazard analysis showed that old age (>=60 years) [hazard ratio (HR), 1.74; p = 0.046], statin use (HR, 2.42; p = 0.017), low platelet count (<100,000/MUL; HR, 2.00; p = 0.039), and variceal bleeding history (HR, 5.12; p < 0.001) were independent factors for HCC development. With regard to survival, Child-Pugh B/C (HR, 3.78; p = 0.039) and low platelet count (<105/MUL; HR, 7.82; p = 0.049) were independent factors. The estimated glomerular filtration rate significantly increased in patients receiving telbivudine (p = 0.047), but decreased in those receiving tenofovir (p < 0.001) at Year 2. Tenofovir use (HR, 1.98; p = 0.005) was one of the independent factors associated with the progression of chronic kidney disease stage. CONCLUSION: Long-term nucleos(t)ide analog therapy does not guarantee against the HCC development and mortality in chronic hepatitis B-related cirrhotic patients. Careful HCC surveillance is necessary in patients with old age, statin use, low platelet count, and variceal bleeding history. PMID- 27720345 TI - Transforming growth factor beta 1 increases collagen content, and stimulates procollagen I and tissue inhibitor of metalloproteinase-1 production of dental pulp cells: Role of MEK/ERK and activin receptor-like kinase-5/Smad signaling. AB - BACKGROUND/PURPOSE: In order to clarify the role of transforming growth factor beta 1 (TGF-beta1) in pulp repair/regeneration responses, we investigated the differential signaling pathways responsible for the effects of TGF-beta1 on collagen turnover, matrix metalloproteinase-3 (MMP-3), and tissue inhibitor of metalloproteinase-1 (TIMP-1) production in human dental pulp cells. METHODS: Pulp cells were exposed to TGF-beta1 with/without pretreatment and coincubation by 1,4 diamino-2,3-dicyano-1,4-bis(o-aminophenyl mercapto)butadiene (U0126; a mitogen activated protein kinase kinase [MEK]/extracellular signal-regulated kinase [ERK] inhibitor) and 4-(5-benzol[1,3]dioxol-5-yl-4-pyrldin-2-yl-1H- imidazol-2-yl) benzamide hydrate (SB431542; an activin receptor-like kinase-5/Smad signaling inhibitor). Sircol collagen assay was used to measure cellular collagen content. Culture medium procollagen I, TIMP-1, and MMP-3 levels were determined by enzyme linked immunosorbent assay. RESULTS: TGF-beta1 increased the collagen content, procollagen I, and TIMP-1 production, but slightly decreased MMP-3 production of pulp cells. SB431542 and U0126 prevented the TGF-beta1-induced increase of collagen content and TIMP-1 production of dental pulp cells. CONCLUSION: These results indicate that TGF-beta1 may be involved in the healing/regeneration processes of dental pulp in response to injury by stimulation of collagen and TIMP-1 production. These events are associated with activin receptor-like kinase 5/Smad2/3 and MEK/ERK signaling. PMID- 27720346 TI - A fatal case of melioidosis with pancytopenia in a traveler from Indonesia. AB - Melioidosis, an infectious disease with high mortality, caused by Burkholderia pseudomallei, is endemic in southeast Asia and northern Australia. In Indonesia, autochthonous cases have been rarely reported, with most cases being sporadic and occurring in travelers. Herein, we report a fatal case of neurological melioidosis in a traveler from Indonesia presenting with septic shock. PMID- 27720347 TI - Counselling adults who experience a first seizure. AB - PURPOSE: A first seizure can result in significant uncertainty, fear and apprehension. One of the key roles of the clinician in the setting of first seizure is to provide accurate, timely information and counselling. METHOD: We review the numerous components to be considered when counselling an adult patient after a first seizure. RESULTS: We provide a framework and manner to provide that counselling. We focus on an individualized approach and provide recommendations and information on issues of diagnosis, etiology, prognosis, the role and importance of medical testing, lifestyle considerations, driving, medication and other key counselling considerations. CONCLUSION: Accurate, timely counselling can allay fears and anxieties, remove misconceptions and reduce the risk for injury in seizure recurrence. PMID- 27720348 TI - Scientific evidence and daily food for a better life: Milan, 19 June 2015. AB - This paper presents a report of a nutrition conference held at EXPO 2015 in Milan. Over the course of a day, seven speakers from four continents discussed the evidence and scientific processes that underpin the development of dietary guidelines, highlighting issues and challenges at each stage. These include the quality of studies associating disease outcomes with diet, specifically a reliance on observational studies, short duration of intervention trials, low statistical power and lack of follow-up. Concerns were raised over the oversimplification of dietary messages which promote carbohydrates in general without evidence of benefit, while restricting fats when meta-analyses suggests that different fatty acids have different effects on disease risk. The merits of food-based dietary guidelines and holistic dietary patterns were described, whereas the impact of increasing or reducing consumption of individual food groups or macronutrients remains unclear. The meeting ended with a restatement of the importance of dietary guidelines, and associated education, to improve public health, but a plea was made to ensure that the process of setting guidelines is evidence based, responsive and considers the impact of the whole diet. PMID- 27720349 TI - Modulators of the extracellular matrix and risk of anterior cruciate ligament ruptures. AB - OBJECTIVES: The extracellular matrix (ECM) of ligaments continuously undergoes remodelling in order to maintain tissue homeostasis. Several key mediators of ECM remodelling were chosen for investigation in the present study. It is thought that polymorphisms within genes encoding signalling molecules may contribute to inter-individual variation in the responses to mechanical loading, potentially altering risk of injury. DESIGN: A genetic association study was conducted on 232 asymptomatic controls (CON) and 234 participants with surgically diagnosed anterior cruciate ligament (ACL) ruptures; of which 135 participants reported a non-contact mechanism of injury (NON subgroup). METHODS: All participants were genotyped for ten variants in eight genes encoding ECM remodelling proteins. Haplotypes and allele combinations were also inferred. RESULTS: The CASP8 rs3834129 ins allele was significantly over-represented in the male CON group compared to the male NON subgroup (p=0.047, OR: 1.46, 95% CI: 1.01-2.12). In female participants, the IL1B rs16944 TT genotype was significantly under represented in the CON group compared to the NON subgroup (p=0.039, OR: 3.06, 95% CI: 1.09-8.64). Haplotype analysis revealed an under-representation of the CASP8 rs3834129-rs1045485 del-G haplotype in the CON group compared to both the ACL group (p=0.042; haplo.score:2.03) and the NON subgroup (p=0.037; haplo.score:2.09). Furthermore, following a pathway-based approach, genetic variants involved in the cell signalling cascade were associated with ACL injury risk. CONCLUSIONS: The novel independent associations and allele combinations observed implicate the apoptosis and cell signalling cascades as potential contributors to ACL injury susceptibility. Furthermore, these genetic variants may potentially modulate ECM remodelling in response to loading and ultimately contribute to ligament capacity. PMID- 27720350 TI - Cytogenetic and immunohistochemical characterization of mammary analogue secretory carcinoma of salivary glands. AB - OBJECTIVES: Mammary analogue secretory carcinoma (MASC), initially considered a subset of acinic cell carcinoma (ACC), harbors an ETV6 translocation [t(12:15)(p13:25 q)] and is now regarded as a distinct entity. Several putative markers to differentiate MASC from ACC have been reported; however, the immunohistochemical profile is still being explored and updated. The purpose of this study was to further explore the cytogenetic and immunohistochemical profile of MASC. STUDY DESIGN: Cases were analyzed for ETV6 translocation using fluorescent in situ hybridization and stained for CK8, amylase, mammaglobin, GCDFP-15, MUC1, MUC4, STAT5a, Ki-67 (n = 37), CK7, Cam5.2, CK14, SMA, p63, S100, vimentin and DOG1 (n = 42). Histochemical stains for mucins were also performed and data collected for age, sex, and site. RESULTS: Fluorescent in situ hybridization showed 9 cases with ETV6 rearrangement and 2 with increased ETV6 copies. These 11 cases showed an absence of PAS-D-resistant granules, with 10 of 11 showing strong S100, mammaglobin, and STAT5a staining. All ACCs showed diffuse DOG1 staining, whereas 8/11 MASCs were negative and 3 showed only focal DOG1 staining. CONCLUSION: DOG1 can be used in conjunction with PAS-D, S100, and mammaglobin to identify MASCs. Cases with increased ETV6 copies are a novel finding with a similar immunostaining profile and should be considered as MASCs. PMID- 27720351 TI - Scalp mass in a 66-year-old female.

PMID- 27720354 TI - Simple protein precipitation extraction technique followed by validated chromatographic method for linezolid analysis in real human plasma samples to study its pharmacokinetics. AB - Fast and sensitive HPLC method was developed, optimized and validated for quantification of linezolid (LNZ) in human plasma using guaifenesin as an internal standard (IS). Analyte and IS were extracted from plasma by simple protein precipitation extraction technique using methanol as the precipitating solvent. The pretreated samples were injected in a mobile phase formed of acetonitrile:water:methanol (20:70:10v/v/v) in an isocratic mode at a flow rate of 1.5mL/min with UV detection at 251nm. Separation was done using Aglient ODS C18. The method showed linearity in the range of 0.75-50MUg/mL with correlation coefficients equals to 0.9991. Precision and accuracy were in conformity with the criteria normally accepted in bio-analytical method validation. The RSDs for intra- and inter-day assays were <3.56 and 4.63%, respectively. The intra- and inter-day accuracies were 94.67-98.28% and 91.25-96.18%, respectively. The mean absolute recoveries ranged from 92.56+/-1.78 to 95.24+/-2.84. According to stability results, LNZ was stable in human plasma during the storage and analysis. LNZ a pharmacokinetic behavior was studied by applying the proposed analytical method. PMID- 27720355 TI - Bioanalytical method development and validation: Critical concepts and strategies. AB - Bioanalysis is an essential part in drug discovery and development. Bioanalysis is related to the analysis of analytes (drugs, metabolites, biomarkers) in biological samples and it involves several steps from sample collection to sample analysis and data reporting. The first step is sample collection from clinical or preclinical studies; then sending the samples to laboratory for analysis. Second step is sample clean-up (sample preparation) and it is very important step in bioanalysis. In order to reach reliable results, a robust and stable sample preparation method should be applied. The role of sample preparation is to remove interferences from sample matrix and improve analytical system performance. Sample preparation is often labor intensive and time consuming. Last step is the sample analysis and detection. For separation and detection, liquid chromatography-tandem mass spectrometry (LC-MS/MS) is method of choice in bioanalytical laboratories. This is due to high selectivity and high sensitivity of the LC-MS/MS technique. In addition the information about the analyte chemical structure and chemical properties is important to be known before the start of bioanalytical work. This review provides an overview of bioanalytical method development and validation. The main principles of method validation will be discussed. In this review GLP and regulated bioanalysis are described. Commonly used sample preparation techniques will be presented. In addition the role of LC MS/MS in modern bioanalysis will be discussed. In the present review we have our focus on bioanalysis of small molecules. PMID- 27720356 TI - Relationships Between Demographic, Clinical, and Health Care Provider Social Support Factors and Internalized Stigma in People Living With HIV. AB - Internalized HIV stigma (IHS) threatens people living with HIV (PLWH) and the public. Our purpose was to identify relationships between PLWH perceptions of IHS and demographic, clinical, overall health, health-related quality of life, and perceived health care provider (HCP) social support. Using survey data from PLWH (n = 292) in an urban HIV clinic, we first examined the reliability and validity of an existing IHS measure. Exploratory factor analysis revealed that the IHS score was composed of three factors: (a) Perception of Negative Societal Beliefs, (b) Fear of Disclosure, and (c) Perception of Negative HCP Beliefs, which were used as dependent variables in the multivariate analysis. In multivariate regression models, gender, education, quality of life, Getting Needed Care, and Trust in HCP were significantly related to at least one IHS factor. Our findings advance the measurement of IHS and provide a foundation for intervention development to reduce IHS in care settings. PMID- 27720357 TI - A Medical Care Missed Opportunity: Preexposure Prophylaxis and Young Black Men Who Have Sex With Men. AB - PURPOSE: HIV disproportionately impacts young black men who have sex with men (YBMSM). Preexposure prophylaxis (PrEP) is an effective strategy that can avert new HIV infections in YBMSM. Barriers exist for YBMSM to access PrEP. METHODS: We sought to determine factors associated with awareness of and willingness to take PrEP in a sample of YBMSM. RESULTS: Only 8% were currently on PrEP despite many (66%) reporting condomless anal sex, a recent provider visit (54%), disclosing their sexual orientation to their regular medical provider (62%), or a willingness to take PrEP (62%). In bivariate analysis, increased number of lifetime partners, current PrEP use, and disclosure of sexual orientation to a doctor were associated with awareness of PrEP, while condomless anal sex and higher perceived risk was associated with willingness to take PrEP. Sex with females was associated with lower willingness. CONCLUSIONS: Providers may be missing key opportunities to educate YBMSM about PrEP and incorporate PrEP into comprehensive sexual health care. PMID- 27720359 TI - Comparison the effects of two types of therapeutic exercises Frenkele vs. Swiss ball on the clinical balance measures in patients with type II diabetic neuropathy. AB - BACKGROUND: The number of diabetic patients is increasing in the world. Peripheral neuropathy is the most important problem of diabetes. Neuropathy eventually leads to balance impairment which is the main cause of falling down in these patients However, not sufficient evidences available to compare different protocols for improving balance in diabetic patients. OBJECTIVE: This study aimed to compare the effects of two therapeutic exercises on clinical balance measures in patients with type II diabetic peripheral neuropathy. METHODS: The study was performed on 60 patients with diabetes categorized randomly into three groups: an intervention group (N=20) that received ball training exercise, another intervention group (N=20) that received Frenkel exercise and a control group (N=20) that received no interventions. Exercise training session was performed for 3 weeks. Then, clinical balance measures were computed in the three groups. Paired t-test and one-way ANOVA were used to analyze the collected data. RESULTS: Both types of therapeutic exercise programs significantly improved balance in single leg stance, star excursion test, and Berg balance scale test (P?0.05) compared to the control group. Besides, this was more significant in the ball training group (P?0.05). CONCLUSIONS: To improve balance in diabetic neuropathy, Swiss ball exercise is preferred compared to Frenkel training. PMID- 27720358 TI - Association Between Electronic Cigarette Marketing Near Schools and E-cigarette Use Among Youth. AB - PURPOSE: Electronic cigarettes (e-cigarettes) are now the most popular tobacco product among youth. Little is known about the relationship between exposure to e cigarette marketing at the point-of-sale and youth e-cigarette use. METHODS: Research staff collected data on e-cigarette availability and promotion in tobacco retailers within a half-mile of 41 schools participating in the 2014 New Jersey Youth Tobacco Survey. These data were linked with participant responses from the New Jersey Youth Tobacco Survey (n = 3,909) and log-Poisson regression models estimated adjusted prevalence ratios for ever and past-month e-cigarette use. RESULTS: Nearly a quarter of high school students in New Jersey have tried e cigarettes (24.1%) and 12.1% were past-month users. Prevalence was highest among males, non-Hispanic whites, and students who have used other tobacco products. After controlling for covariates and the clustered nature of the data, e cigarette retailer density around schools was positively associated with ever and past-month use of e-cigarettes (p < .05). E-cigarette advertising volume significantly increased the probability of being a past-month e-cigarette user (adjusted prevalence ratio: 1.03, p = .031). CONCLUSIONS: This study suggests that the point-of-sale environment around schools may contribute to e-cigarette use among youth. Policy efforts to restrict tobacco promotion at the point-of sale may play a role in reducing the use of e-cigarettes.

AB - AIMS: Nasal carriage of Staphylococcus aureus in diabetic patients may be a risk factor for diabetic foot lesion infections. The aims of this study were to compare the genotypic profiles of S. aureus strains isolated from nares and diabetic foot ulcers (DFUs) using microarray technology. METHODS: Patients were included if they were admitted for diabetic foot infection (DFI) at any of three diabetology departments of Montpellier and Nimes University Hospitals between 1 September 2010 to 30 June 2012. All S. aureus isolates were analyzed using oligonucleotides arrays; S. aureus resistance and virulence genes were determined and each isolate was affiliated to a clonal complex. RESULTS: The prevalence of S. aureus nasal carriage among the 276 included patients was 39.5% (n=109), while 36.6% (n=101) had S. aureus at both sites (nares and foot wounds) and, of these patients, 65.3% of patients harboured the same strain at both sites. In addition, the spread of the methicillin-resistant S. aureus (MRSA) ST398 clone in DFI and its tropism for bone were also further confirmed. CONCLUSION: These findings appear to provide new arguments in favour of the systematic detection of nasal S. aureus carriage to anticipate the management of DFI. PMID- 27720362 TI - Cancer of Unknown Primary: a Cancer Registry Study of Factors Affecting Access to Diagnosis. AB - AIM: A potential impact of the centralisation of cancer services in the UK is difficulty in gaining access for members of the population living far from them. This could lead to delayed presentation of cancer with more advanced disease and clinical deterioration at diagnosis. A patient may be recorded in the cancer registry as having cancer of unknown primary (CUP) if the clinical state at presentation precludes investigation. Other patients may be so recorded if investigation identifies sites of metastatic tumour but the primary is not found. We hypothesised that the first group would include more patients who experienced difficulties in gaining access to health services through residing in deprived areas or through poorer geographical access to healthcare facilities. MATERIALS AND METHODS: We compared the diagnosis of CUP with a comparator tumour, carcinoma of the rectum, where diagnosis is facilitated by an alarm symptom and where variations in access are lower. Records from the Northern and Yorkshire Cancer Registry from 1994 to 2002 with ICD 10 C77-C80 (CUP, including categories where investigations may have been incomplete or no primary cancer was found) and C20 (malignant neoplasm of rectum) were combined with travel time to services (primary care, secondary and tertiary services) and the Index of Multiple Deprivation. Logistic regression modelled predictors of CUP were compared with C20 and, within CUP, the odds of a histological basis of diagnosis. RESULTS: The registry classified 7428 patients as C80, 8849 as C77-C79, and 10 804 as C20. Compared with C20, the number of cases of C80 showed a statistically significant increasing trend with increasing travel time to primary care. Risk also increased strongly with age and deprivation. The results for C77-C79 were similar to those for C80, except that the travel time to primary care showed no effect. Considering all CUP alone, histological diagnosis significantly declined with travel time to the nearest hospital. There was no association with gender and the likelihood of histological diagnosis, but a marked decline with age, a downward trend with deprivation, and an increase when the nearest hospital was a cancer centre. CONCLUSIONS: These findings facilitate the understanding of factors associated with the group of patients that includes those with the least effective access to cancer services. PMID- 27720364 TI - Editorial overview: Growth and development: prokaryotes. PMID- 27720363 TI - Blood pressure and urolithiasis in children. AB - INTRODUCTION: Urolithiasis is a condition that is most commonly found in adults, but is becoming increasingly prevalent in children. Little is known about the relationship between blood pressure (BP) and urolithiasis in children. OBJECTIVES: The aim was to evaluate the relationship between urolithiasis and BP, and to determine the association of BP with 24-h urine parameters in children. METHODS: We retrospectively analyzed BP and 24-h urine data from children <18 years with and without urolithiasis from 2004 to 2015 at a single tertiary center. Children with a diagnosis of non-glomerular hematuria without history of urolithiasis were chosen as the control group. Non-stone formers were excluded if they presented with any abnormal 24-h urine data or kidney disease. Casual BP, BP index (BPi), and 24-h urine parameters were compared between groups using t tests. Multiple regression analyses adjusting for age, sex and body mass index (BMI) z-score evaluated the association of BP with urolithiasis and urine electrolytes. RESULTS: The urolithiasis group (N = 71) was significantly older, taller and heavier than the non-stone former group (N = 53) (Table). Systolic BP and diastolic BP in stone formers were significantly greater than in non-stone formers, respectively (p = 0.019). Additionally, systolic BPi was significantly higher in the urolithiasis group (p = 0.03) but there was no significant difference in diastolic BPi (p = 0.45). Urolithiasis was a significant predictor of systolic BPi in the adjusted model (beta = 0.04, 95% CI 0.001-0.07). In stone formers, systolic BP and systolic BPi were directly associated with 24-h urine sodium, oxalate/1.73 m2, and uric acid (all p < 0.05). Urine calcium was not associated with any BP parameter. DISCUSSION: The findings are consistent with previous studies in adults that examined the correlation between blood pressure and kidney stones. The results of this study also showed that blood pressure was positively associated with urine sodium, oxalate, and uric acid. Interestingly, contrary to adult literature, our hypothesis which postulated that blood pressure would be associated with an increase in urine calcium was not supported by our findings. The small sample size is a study limitation and the use of healthy controls as a comparison would have been ideal. CONCLUSIONS: Blood pressure was directly associated with urolithiasis children. Greater BP values were also associated with abnormalities in 24-h urine oxalate, uric acid, and sodium values. Interestingly, BP was not associated with urine calcium in this population. PMID- 27720365 TI - Circumventing Brain Barriers: Nanovehicles for Retroaxonal Therapeutic Delivery. AB - In addition to safeguarding the central nervous system (CNS) from the vast majority of pathogens and toxins, transvascular barriers impose immense challenges to the delivery of beneficial cargo. A few toxins and neurotropic viruses capable of penetrating the brain have proved to be potentially valuable for neuron targeting and enhanced transfer of restorative medicine and therapeutic genes. Here we review molecular concepts and implications of the highly neurotropic tetanus toxin (TeTx) and botulinum neurotoxins (BoNTs) and their ability to infiltrate and migrate throughout neurons. We discuss recent applications of their detoxified variants as versatile nanovehicles for retroaxonal delivery of therapeutics to motor neurons and synapses. Continued advances in research on these remarkable agents in preclinical trials might facilitate their future use for medical benefit. PMID- 27720366 TI - Causes and estimated incidences of sex-chromosome misdiagnosis in preimplantation genetic diagnosis of aneuploidy. AB - Preimplantation genetic diagnosis of aneuploidy (PGD-A) with comprehensive chromosome analysis has been known to improve pregnancy outcomes. Accuracy in detecting sex chromosomes becomes important when selecting against embryos at risk for sex-linked disorders. A total of 21,356 PGD-A cycles consisting of day-3 (cleavage) or day-5 (blastocyst) biopsies were received at the same laboratory for PGD-A via fluorescence in situ hybridization (FISH) or array comparative genome hybridization (aCGH) from multiple fertility centres. The misdiagnosis rates were 0.12% (Wilson 95% CI 0.05 to 0.25%) in day-3 FISH cycles, 0.48% (Wilson 95% CI 0.19 to 1.22%) in day-3 aCGH cycles and 0.0% (Wilson 95% CI 0 to 0.26) in day-5 aCGH cycles. Although rare, the likely causative biological event for true misdiagnosis is embryonic XX/XY mosaicism. Reanalysis of 1219 abnormal cleavage-stage research embryos revealed a 73% incidence of minor and major mosaicism. Only four (0.3%) embryos were found to be diploid and contained XX and XY cells that could potentially account for the misdiagnosis of sex. Our investigation identified errors leading to misdiagnosis and their attribution to specific events during PGD-A testing. The reported misdiagnosis rates suggest that PGD-A for sex determination is highly accurate, particularly when using aCGH applied to blastocyst biopsies. PMID- 27720367 TI - Neuroendocrine Tumors of the Thymus: Analysis of Factors Affecting Survival in 254 Patients. AB - BACKGROUND: Neuroendocrine tumors of the thymus (NETT) constitute less than 5% of all anterior mediastinal masses but are aggressive and lead to poor overall survival. This study was designed to evaluate factors that influence the prognosis of patients with NETT and the role of surgical intervention in survival. METHODS: We analyzed the Surveillance, Epidemiology, and End Results cancer database to identify patients with NETT. We performed univariate and multivariate analyses to identify prognostic factors among demographic, tumor, and treatment variables. RESULTS: In 254 patients identified with NETT, the median overall survival time was 73 months, with a 5-year survival rate of 56%. Patients who underwent surgical therapy had a significantly longer median survival time than did those who did not undergo surgical therapy (109 months vs 46 months, p < 0.001). In multivariate analysis, surgical resection, Masaoka-Koga stage, and tumor size were significant predictors of survival. CONCLUSIONS: Our study found that surgical resection, Masaoka-Koga stage, and tumor size are significant prognostic factors in patients with NETT. Complete surgical resection continues, rightfully, to be the mainstay in the treatment of this rare disease. PMID- 27720369 TI - Extubation Failure in Neonates After Cardiac Surgery: Prevalence, Etiology, and Risk Factors. AB - BACKGROUND: The purpose of this study was to explore the prevalence, etiology, and risk factors of extubation failure (EF) in post-cardiac surgery neonates. METHODS: Neonates (30 days old or younger) who underwent cardiac surgery and were admitted to the cardiac intensive care unit between September 2010 and February 2016 were included. The prevalence and etiology of EF, defined as reintubation within 48 hours, were reviewed. Demographic, operative, and perioperative data were retrospectively collected. Multiple logistic regression models were constructed to identify the risk factors for EF. RESULTS: The median age at surgery was 10 days. Extubation failure occurred in 25 of 156 cases (16.0%; 95% confidence interval: 10.6% to 22.7%), because of respiratory dysfunction (n = 16), hemodynamic instability (n = 4), upper airway obstruction (n = 4), or gastrointestinal bleeding (n = 1). Subsequent extubations were successful in 17 cases (68%) because of medical optimization of the causes of reintubation. The remaining 8 cases needed surgical reintervention, including tracheostomy and cardiac surgery. The inhospital mortality rate was 2.6%. In a bivariate analysis, younger age, airway diseases, ventilation before surgery, prolonged mechanical ventilation, and delayed sternal closure were associated with EF. The multivariable analysis identified airway diseases (adjusted odds ratio 18.2, 95% confidence interval: 3.8 to 88.6, p = 0.0003) and mechanical ventilation longer than 7 days (adjusted odds ratio 8.2, 95% confidence interval: 1.9 to 34.9, p = 0.0046) as risk factors for EF. CONCLUSIONS: The prevalence of EF is relatively high in neonatal cardiac surgery. The etiologies can be diverse. Extubation of neonates at high risk after cardiac surgery, based on these possible risk factors, requires more diligent approaches. PMID- 27720368 TI - Screening for Frailty in Thoracic Surgical Patients. AB - BACKGROUND: The presence of frailty or prefrailty in older adults is a risk factor for postsurgical complications. The frailty phenotype can be improved through long-term resistance and aerobic training. It is unknown whether short term preoperative interventions targeting frailty will help to mitigate surgical risk. The purpose of this study was to determine the proportion of frail and prefrail patients presenting to a thoracic surgical clinic who could benefit from a frailty reduction intervention. METHODS: A prospective cohort study was performed at a single-site thoracic surgical clinic. Starting October 1, 2014, surgical candidates 60 years of age or older who consented to be screened were included. Patients were screened using an adapted version of Fried's phenotypic frailty criteria: weakness (grip strength), slow gait (15-foot walk), unintentional weight loss, self-reported exhaustion, and low self-reported physical activity (Physical Activity Scale for the Elderly). Prefrailty was identified when participants demonstrated one to two frailty characteristics; frailty was identified when participants demonstrated three to five frailty characteristics. RESULTS: Of 180 eligible patients, 126 consented, and 125 completed screening. Thirty-nine participants (31%) were not frail, 71 (57%) were prefrail, and 15 (12%) were frail. Exhaustion was the most common frailty symptom (34%). Frailty prevalence did not significantly differ among men and women (men: 10%, women: 14%; p = 0.75). CONCLUSIONS: We found a high proportion of prefrail and frail patients among patients deemed candidates for thoracic surgical procedures. This finding indicates that frailty may be underrecognized. Substantial numbers of patients may be considered for a presurgical frailty reduction intervention. PMID- 27720370 TI - How Does Mitral Valve Repair Fail in Patients With Prolapse?-Insights From Longitudinal Echocardiographic Follow-Up. AB - BACKGROUND: Repair of mitral regurgitation (MR) caused by prolapse has been well validated. Although favorable early and late results after repair have been reported, few data are available that mechanistically describe how a mitral repair fails beyond the mere need for mitral valve reoperation. We therefore sought to determine the modes of valve repair failure in patients who underwent surgical correction of MR caused by prolapse. METHODS: Between 2001 and 2015, 855 patients underwent repair of MR caused by prolapse. Patients were a mean age of 63.7 +/- 12.7 years, and 380 (44%) had bileaflet prolapse. The overall repair rate was 97.2%. These patients were monitored as part of a cohort initiative and underwent serial clinical and echocardiographic assessments at 1, 3 to 6, and 12 months after the operation. Beyond the first year of the MR repair, patients were assessed by echocardiography every 1 to 2 years or when clinically indicated. Clinical and echocardiographic follow-up averaged 4.3 +/- 3.5 years. RESULTS: Freedom from recurrent MR of 2+ or higher was 92.4% +/- 1.3% at 5 years and 86.6% +/- 2.4% at 10 years. Overall, recurrent MR of 2+ or higher developed in 49 patients (5.7%) at a mean of 3.1 +/- 2.5 years after the repair, of whom 14 (1.6%) had recurrent MR of 3+ or 4+. Among patients with bileaflet prolapse, recurrent MR of 2+ or higher was observed in 24, of whom 9 had 3+ or 4+ MR., The development of recurrent MR of 2+ or higher was categorized as prolapse in 6 and nonprolapse in 43. Severe mitral stenosis occurred in 3 patients at 8.2 years after the MR repair. Mitral reoperation was ultimately performed in 21 patients. Patients who had recurrent MR 2+ or higher within the first year after the operation were more likely to undergo a subsequent mitral valve reoperation (incident rate ratio, 5.2 +/- 2.9; p = 0.003), although no association between recurrent MR and reoperation was observed after the first year. CONCLUSIONS: Severe MR after repair is rare, although some may have recurrent moderate MR. Patients who required a subsequent mitral valve reoperation were most likely to have recurrent MR of 2+ or higher within the first year after the operation. PMID- 27720371 TI - Delayed Sternal Closure in Infant Heart Surgery-The Importance of Where and When: An Analysis of the STS Congenital Heart Surgery Database. AB - BACKGROUND: Delayed sternal closure (DSC) is commonly used to optimize hemodynamic stability after neonatal and infant heart surgery. We hypothesized that duration of sternum left open (SLO) was associated with rate of infection complications, and that location of sternal closure may mitigate infection risk. METHODS: Infants (age <=365 days) undergoing index operations with cardiopulmonary bypass and DSC at STS Congenital Heart Surgery Database centers (from 2007 to 2013) with adequate data quality were included. Primary outcome was occurrence of infection complication, defined as one or more of the following: endocarditis, pneumonia, wound infection, wound dehiscence, sepsis, or mediastinitis. Multivariable regression models were fit to assess association of infection complication with: duration of SLO (days), location of DSC procedure (operating room versus elsewhere), and patient and procedural factors. RESULTS: Of 6,127 index operations with SLO at 100 centers, median age and weight were 8 days (IQR, 5-24) and 3.3 kg (IQR, 2.9-3.8); 66% of operations were STAT morbidity category 4 or 5. At least one infection complication occurred in 18.7%, compared with 6.6% among potentially eligible neonates and infants without SLO. Duration of SLO (median, 3 days; IQR, 2-5) was associated with an increased rate of infection complications (p < 0.001). Location of DSC procedure was operating room (16%), intensive care unit (67%), or other (17%). Location of DSC was not associated with rate of infection complications (p = 0.45). CONCLUSIONS: Rate of occurrence of infectious complications is high among infants with sternum left open following cardiac surgery. Longer duration of SLO is associated with increased infection complications. PMID- 27720372 TI - How to perform 3D reconstruction of skull base tumours. AB - The surgical management of skull base lesions is difficult due to the complex anatomy of the region and the intimate relations between the lesion and adjacent nerves and vessels. Minimally invasive approaches are increasingly used in skull base surgery to ensure an optimal functional prognosis. Three-dimensional (3D) computed tomography (CT) reconstruction facilitates surgical planning by visualizing the anatomical relations of the lesions in all planes (arteries, veins, nerves, inner ear) and simulation of the surgical approach in the operating position. Helical CT angiography is performed with optimal timing of the injection in terms of tumour and vessel contrast enhancement. 3D definition of each structure is based on colour coding by automatic thresholding (bone, vessels) or manual segmentation on each slice (tumour, nerves, inner ear). Imaging is generally presented in 3 dimensions (superior, coronal, sagittal) with simulation of the surgical procedure (5 to 6 reconstructions in the operating position at different depths). PMID- 27720373 TI - Diagnostic and prognostic contribution of laryngeal electromyography in unilateral vocal-fold immobility in adults. AB - OBJECTIVES: To study the diagnostic and prognostic contribution of laryngeal electromyography in unilateral vocal-fold immobility in adults. MATERIAL AND METHODS: A retrospective study included patients with unilateral vocal-fold immobility undergoing laryngeal electromyography between 2007 and 2015. Neurogenic, normal or myogenic findings were compared to the clinical aspect. Prognosis for recovery was assessed from motor unit potentials on laryngeal electromyography, and compared to subsequent progress on laryngoscopy. RESULTS: Sixty-three patients (mean age, 59 years) were initially included; 2 were subsequently excluded from analysis. Mean time from onset of immobility to laryngeal electromyography was 7 months. 85% of the 61 patients showed neurogenic findings, indicating neural lesion; 13% showed normal electromyography, indicating cricoarytenoid joint ankylosis; and 1 patient showed a myogenic pattern. Neurogenic cases were usually secondary to cervical surgery. Thirty eight patients were followed up. In total, 75% of patients showing reinnervation potentials recovered. The positive predictive value of laryngeal electromyography was 69.2%. CONCLUSION: Laryngeal electromyography is effective in specifying the origin of unilateral vocal-fold immobility in adults. It also has a prognostic role, lack of reinnervation potentials being a possible indication for early medialization surgery. PMID- 27720374 TI - Trauma networks and rural trauma. PMID- 27720375 TI - Coracoid bone block fixation with cortical buttons: An alternative to screw fixation? AB - BACKGROUND: The purpose of this study was to evaluate suture button fixation in a bone block (Bristow and Latarjet) procedure. We hypothesize that (1) cortical button fixation will allow predictable and reproducible bone union and (2) minimize the complications reported with screw fixation. MATERIALS AND METHODS: Seventy patients (mean age, 27 years) underwent an arthroscopic bone block procedure with a guided surgical approach and suture button fixation for recurrent anterior shoulder instability. There were two groups of patients: 35 Bristow procedures (group A) and 35 Latarjet procedures (group B). Bone graft union and positioning accuracy were assessed by postoperative computed tomography imaging at 2 weeks and 6 months, respectively. RESULTS: The coracoid graft was positioned below the equator in 93% and strictly tangential to the glenoid surface in 94% of the cases. Bone healing was observed in 83% of the cases (58/70) with 74% bone union in group A and 91% in group B. Neurologic and hardware complications, classically reported with screw fixation, were not observed with this novel fixation method. CONCLUSIONS: (1) Suture button fixation can be an alternative to screw fixation, obtaining bone block union, (2) in the lying position (Latarjet) bone healing was better than in the standing position (Bristow), and (3) complications classically reported with screw fixation were not observed. LEVEL OF EVIDENCE: Level IV. PMID- 27720376 TI - Anterior cervical interbody fusion using polyetheretherketone cage filled with synthetic bone graft in acute cervical spine injury. AB - PURPOSE: The aim of this study was to assess the interbody fusion rate for patients treated by anterior cervical interbody fusion (ACIF) using polyetheretherketone (PEEK) cages filled with synthetic bone graft in acute cervical spine injury. MATERIALS AND METHODS: Twenty-nine patients (mean age: 49 years) with monosegmental instability due to cervical spine injury were followed. We assessed the rate of and time to interbody fusion at 1-year follow-up. In case of secondary displacement, we analysed its causes and surgical management. RESULTS: The rate of fusion was 86.2%. The mean time to fusion was 7.2 months. Interbody fusion was observed at 3 months in 4 patients, at 6 months in 14 and at 1 year in 7. Four patients had secondary displacement within 3 months. CONCLUSION: ACIF with a PEEK cage filled with synthetic bone graft seems to be an alternative to iliac crest bone graft with no morbidity related to the harvest site. PMID- 27720378 TI - Metformin: Candidate host-directed therapy for tuberculosis in diabetes and non diabetes patients. AB - Despite major advances in tuberculosis (TB) control, TB continues to be a leading cause of death worldwide. The discovery of new anti-TB treatment drugs and regimens that target drug-sensitive and drug-resistant TB are being complemented with a search for adjunct host-directed therapies that synergize for Mycobacterium tuberculosis (Mtb) elimination. The goal of host-directed therapies is to boost immune mechanisms that diminish excess inflammation to reduce lung tissue damage and limit Mtb growth. Metformin is the most commonly-used medication for type 2 diabetes, and a candidate for host-directed therapy for TB. Preliminary data suggests metformin may be beneficial for TB control by reducing the deleterious inflammation associated with immune pathology and enhancing the anti-mycobacterial activity of immune cells. In this review I summarize current findings, knowledge gaps and the potential benefits as well as points of caution for using metformin as adjunct therapy for TB in patients with and without type 2 diabetes.

PMID- 27720377 TI - Predictive value of serum bradykinin and desArg9-bradykinin levels for chemotherapeutic responses in active tuberculosis patients: A retrospective case series. AB - BACKGROUND: There is an urgent need for methods that can rapidly and accurately assess therapeutic responses in patients with active tuberculosis (TB) in order to predict treatment outcomes. Exposure to bacterial pathogens can rapidly activate the plasma contact system, triggering the release of bradykinin (BK) and its metabolite desArg9-bradykinin (DABK) to induce inflammation and innate immune responses. We hypothesized that serum BK and DABK levels might act as sensitive immune response signatures for changes in Mycobacterium tuberculosis (Mtb) burden, and therefore examined how serum levels of these markers corresponded with anti-TB therapy in a small cohort of active TB cases. METHODS: Nanotrap Mass Spectrometry (MS) was used to analyze serial blood specimens from 13 HIV-negative adults with microbiologically confirmed active TB who were treated with first line anti-TB chemotherapy. MS signal for BK (m/z 1060.5) and DABK (m/z 904.5) serum peptides were evaluated at multiple time-points (before, during, and after treatment) to evaluate how BK and DABK levels corresponded with disease status. RESULTS: Serum BK levels declined from pretreatment baseline levels during the early stage anti-TB therapy (induction phase) and tended to remain below baseline levels during extended treatment (consolidation phase) and after therapy completion. BK levels were consistent with induction phase sputum culture conversions indicative of decreased Mtb burden reflecting good treatment responses. Serum DABK levels tended to increase during the induction phase and decrease at consolidation and post-therapy time points, which may indicate a shift from active disease to chronic inflammation to a disease free state. Elevated BK and DABK levels after treatment completion in one patient may be related to the subsequent recurrent TB disease. CONCLUSIONS: Our pilot data suggests that changes in the circulating BK and DABK levels in adult TB patients can be used as potential surrogate markers of the host response both early and late in anti-TB treatment for both pulmonary and extrapulmonary TB patients. We will further exploit these host-response signatures in the future as biomarkers in combination with other clinical and microbiologic tools which may improve treatment efficacy and facilitate the development of host-directed therapy. PMID- 27720380 TI - Twenty-four hour Holter monitoring in finishing cattle housed outdoors. AB - INTRODUCTION: Atrial premature complexes have been reported to be the most common arrhythmia in cattle and is suspected to be secondary to systemic disease, especially gastrointestinal disease. In order to properly identify pathologic arrhythmia in cattle, the normal rhythm and arrhythmia prevalence should be defined. The objective of this study was to determine the normal heart rate, rhythm, number of ventricular premature complexes (VPCs), and atrial premature complexes (APCs) in unrestrained Angus steers. ANIMALS: Twenty-seven client owned steers with unremarkable physical examinations and serum biochemical analyses were used. MATERIALS AND METHODS: Twenty-four hour Holter monitors, attached by a custom-made harness, were retrospectively evaluated. Three lead electrocardiographic registrations of good quality and normal sinus rhythm were obtained from all steers in the study. RESULTS: The mean heart rate was 66.8 bpm +/- 16.4 bpm. Ventricular premature complexes were rare (noted in 14.8% of steers), and APCs were common (noted in 85% of the steers). Simple second degree AV block was observed in 18.5% of the steers. CONCLUSION: In summary, healthy steers have rare single VPCs, although it is possible for an individual animal to have apparent more frequent VPCs. Mean heart rate varies with a diurnal pattern similar to other species. Atrial premature complexes are the most prevalent abnormality observed in feedlot steers. PMID- 27720381 TI - Borrelia burgdorferi DNA absent, multiple Rickettsia spp. DNA present in ticks collected from a teaching forest in North Central Florida. AB - Tick-borne diseases are an emerging public health threat in the United States. In Florida, there has been public attention directed towards the possibility of locally acquired Borrelia burgdorferi sensu stricto, the causative agent of Lyme disease, in association with the lone star tick. The aim of this study was to determine the prevalence of ticks and the pathogens they carry and potentially transmit, such as B. burgdorferi, in a highly utilized teaching and research forest in North Central Florida. Ticks were collected by dragging and flagging methods over a four month period in early 2014, identified, and tested by PCR for multiple pathogens including Anaplasma, Borrelia, Rickettsia, and Ehrlichia species. During the study period the following ticks were collected: 2506 (96.5%) Amblyomma americanum L., 64 (2.5%) Ixodes scapularis Say, 19 (0.7%) Dermacentor variabilis Say, and 5 (0.2%) Ixodes affinis Neuman. Neither Borrelia spp. (0/846) nor Anaplasma spp. (0/69; Ixodes spp. only) were detected by PCR in any of the ticks tested. However, Rickettsia DNA was present in 53.7% (86/160), 62.5% (40/64), 60.0% (3/5) and 31.6% (6/19) of A. americanum, I. scapularis, I. affinis and D. variabilis, respectively. Furthermore, E. chaffeensis and E. ewingii DNA were detected in 1.3% and 4.4% of adult A. americanum specimens tested, respectively. Although receiving an A. americanum bite is likely in wooded areas in North Central Florida due to the abundance of this tick, the risk of contracting a tick-borne pathogen in this specific area during the spring season appears to be low. The potential for pathogen prevalence to be highly variable exists, even within a single geographical site and longitudinal studies are needed to assess how tick-borne pathogen prevalence is changing over time in North Central Florida. PMID- 27720382 TI - Detection of Candidatus Neoehrlichia mikurensis and Ehrlichia muris in Estonian ticks. AB - So far neglected bacteria like Candidatud Neoehrlichia mikurensis and Ehrlichia muris-like agents get increased attention in the recent past. Ixodid ticks were demonstrated to harbor both of these pathogens. Estonia is populated by two medically important tick species, I. ricinus and I. persulcatus. In this study the presence of E. muris and Candidatus N. mikurensis in these two tick species was investigated. Tick DNA was analyzed by nested PCR and subsequent sequencing for the presence of 16S rRNA of E. muris and Candidatus N. mikurensis. Positive samples were further confirmed by amplification and sequencing of the partial groESL-operon. The obtained partial groESL sequences were used for construction of a maximum likelihood tree. In total, 776 ticks from 36 collection sites situated in 7 counties on the mainland of Estonia and 2 sites situated in one county on the island Saaremaa were collected. 548 were I. ricinus and 228 were I. persulcatus. Only in 5 counties (11 sites) samples positive for the Anaplasmataceae 16S rRNA gene were found. The percentage of Candidatus N. mikurensis positive ticks varied from 1% to 9.1% at different sites. In Eastern and South-Eastern Estonia, the area where I. ricinus and I. persulcatus are sympatric, no Candidatus N. mikurensis was found. Ticks carrying E. muris were found in three counties, the site-specific percentage of positive ticks varied from 1.2% to 25.6%. This is the first study revealing the presence of Candidatus N. mikurensis and E. muris in Estonian ticks. Candidatus N. mikurensis was found only in the western part of the country exclusively in I. ricinus and the phylogenetic analysis revealed close relatedness of the Estonian sequences to other European Candidatus N. mikurensis strains. E. muris was detected mostly in I. persulcatus and only in one I. ricinus in the sympatric area of both tick species. This is in correspondence with the observation that this pathogen is more often found in I. persulcatus than in I. ricinus. This study demonstrates the presence of Candidatus N. mikurensis and E. muris in Estonian ticks and highlights the necessity to raise awareness of symptoms by healthcare professionals.

AB - BACKGROUND: There is no consensual opinion regarding the percutaneous coronary intervention (PCI) procedure for unprotected distal left main (UDLM) lesion. METHODS: Between April 2005 and August 2011, 586 consecutive patients with UDLM stenosis treated with drug-eluting stents were recruited for this study to clarify the impact of combination of full-coverage stenting and proximal optimization technique (POT) for UDLM lesion. An optimal strategy of full coverage stenting and POT was performed in 353 patients and the other 233 patients were not optimally treated. Major adverse cardiovascular events (MACEs) were defined as all-cause death, myocardial infarction, or target lesion revascularization (TLR) during follow-up period. TLRs were also evaluated for main branch (MB) restenosis. RESULTS: At 1615days of follow-up, MACE occurred in 166 (28.3%) patients. The occurrence of MACE and TLR had a trend to being lower in the optimal strategy [propensity score-adjusted HR, 0.73 (95% CI, 0.53-1.01), p=0.05 and propensity score-adjusted HR, 0.69 (95% CI, 0.46-1.02), p=0.06, respectively]. TLR of the MB occurred significantly less frequently in the optimal strategy [propensity score-adjusted HR, 0.34 (95% CI, 0.15-0.76), p=0.008]. Cardiac death occurred in 28 (4.8%) patients. There was no significant difference in cardiac death between the two groups. These results were sustained after propensity-score matching. CONCLUSIONS: An optimal PCI strategy of full coverage stenting and POT might be effective for UDLM lesion to reduce the occurrence of MACE, especially driven by TLR of the MB.

AB - BACKGROUND: Large congenital melanocytic nevi entail significant medical and cosmetic ramifications for patients and families. Reconstruction is a challenging endeavor, especially when the lesion is present on the limbs. The literature describes various methods by which a plastic surgeon can address reconstruction; yet, to date, there has been no series describing a method that provides consistent results with low complication rates. In this study, we describe our surgical technique for reconstruction of the upper extremity after excision of large circumferential CNM with a pre-expanded bi-pedicled flap, namely the "sleeve" flap. METHODS: A systematic review of our database of pediatric patients treated for large and giant nevi was performed. Patients with large and giant circumferential upper extremity nevi were retrieved, and their charts reviewed for demographics, number of procedures performed, duration of follow-up, and complications. RESULTS: Over a course of 12 years, eight patients with large or giant circumferential nevi of the upper extremity were treated at our institution with "sleeve" flap reconstruction. Mean follow-up time was 36 months. A single complication was seen. All reconstructions achieved satisfactory results, both functionally and cosmetically. DISCUSSION: We describe our surgical approach for treating upper extremity large and giant circumferential nevi with pre-expanded bi-pedicled "sleeve" flaps. When properly planned and executed, this technique enables successful treatment of large and giant nevi of the arm and the forearm. Although arduous and complex, the process yields excellent aesthetic results with low complication rates. This technique is promising as the reconstructive option of choice for these difficult lesions. PMID- 27720390 TI - Succession Planning and Management: The Backbone of the Radiology Group's Future. AB - The transition of leadership within radiology practices is often not a planned replacement process with formal development of potential future leaders. To ensure their ongoing success, however, practices need to develop comprehensive succession plans that include a robust developmental program for potential leaders consisting of mentoring, coaching, structured socialization, 360-degree feedback, developmental stretch assignments, job rotation, and formal education. Succession planning and leadership development will be necessary in the future for a practice to be successful in its business relationships and to be financially viable.

AB - The dopamine hypothesis of schizophrenia is supported by a large number of imaging studies that have identified an increase in dopamine binding at the D2 receptor selectively in the striatum. We review a decade of work using a regionally restricted and temporally regulated transgenic mouse model to investigate the behavioral, molecular, electrophysiological, and anatomical consequences of selective D2 receptor upregulation in the striatum. These studies have identified new and potentially important biomarkers at the circuit and molecular level that can now be explored in patients with schizophrenia. They provide an example of how animal models and their detailed level of neurobiological analysis allow a deepening of our understanding of the relationship between neuronal circuit function and symptoms of schizophrenia, and as a consequence generate new hypotheses that are testable in patients. PMID- 27720393 TI - Utility of virtual reality environments to examine physiological reactivity and subjective distress in adults who stutter. AB - PURPOSE: Virtual reality environments (VREs) allow for immersion in speaking environments that mimic real-life interactions while maintaining researcher control. VREs have been used successfully to engender arousal in other disorders. The purpose of this study was to investigate the utility of virtual reality environments to examine physiological reactivity and subjective ratings of distress in persons who stutter (PWS). METHOD: Subjective and objective measures of arousal were collected from 10PWS during four-minute speeches to a virtual audience and to a virtual empty room. RESULTS: Stuttering frequency and physiological measures (skin conductance level and heart rate) did not differ across speaking conditions, but subjective ratings of distress were significantly higher in the virtual audience condition compared to the virtual empty room. CONCLUSION: VREs have utility in elevating subjective ratings of distress in PWS. VREs have the potential to be useful tools for practicing treatment targets in a safe, controlled, and systematic manner. PMID- 27720394 TI - G Protein-coupled Receptor Kinase 2 (GRK2) Promotes Breast Tumorigenesis Through a HDAC6-Pin1 Axis. AB - In addition to oncogenic drivers, signaling nodes can critically modulate cancer related cellular networks to strength tumor hallmarks. We identify G-protein coupled receptor kinase 2 (GRK2) as a relevant player in breast cancer. GRK2 is up-regulated in breast cancer cell lines, in spontaneous tumors in mice, and in a proportion of invasive ductal carcinoma patients. Increased GRK2 functionality promotes the phosphorylation and activation of the Histone Deacetylase 6 (HDAC6) leading to de-acetylation of the Prolyl Isomerase Pin1, a central modulator of tumor progression, thereby enhancing its stability and functional interaction with key mitotic regulators. Interestingly, a correlation between GRK2 expression and Pin1 levels and de-acetylation status is detected in breast cancer patients. Activation of the HDAC6-Pin1 axis underlies the positive effects of GRK2 on promoting growth factor signaling, cellular proliferation and anchorage independent growth in both luminal and basal breast cancer cells. Enhanced GRK2 levels promote tumor growth in mice, whereas GRK2 down-modulation sensitizes cells to therapeutic drugs and abrogates tumor formation. Our data suggest that GRK2 acts as an important onco-modulator by strengthening the functionality of key players in breast tumorigenesis such as HDAC6 and Pin1. PMID- 27720397 TI - A local mechanism by which alcohol consumption causes cancer. AB - Epidemiological data indicate that 5.8% of cancer deaths world-wide are attributable to alcohol consumption. The risk of cancer is higher in tissues in closest contact on ingestion of alcohol, such as the oral cavity, pharynx and esophagus. However, since ethanol is not mutagenic and the carcinogenic metabolite of ethanol (acetaldehyde) is mostly produced in the liver, it is not clear why alcohol use preferentially exerts a local carcinogenic effect. It is well known that ethanol causes cell death at the concentrations present in alcoholic beverages; however, this effect may have been overlooked because dead cells cannot give rise to cancer. Here I discuss that the cytotoxic effect of ethanol on the cells lining the oral cavity, pharynx and esophagus activates the division of the stem cells located in deeper layers of the mucosa to replace the dead cells. Every time stem cells divide, they become exposed to unavoidable errors associated with cell division (e.g., mutations arising during DNA replication and chromosomal alterations occurring during mitosis) and also become highly vulnerable to the genotoxic activity of DNA-damaging agents (e.g., acetaldehyde and tobacco carcinogens). Alcohol consumption may increase the risk of developing cancer of the oral cavity, pharynx and esophagus by promoting the accumulation of cell divisions in the stem cells that maintain these tissues in homeostasis. Understanding the mechanisms of carcinogenicity of alcohol is important to reinforce the epidemiological evidence and to raise public awareness of the strong link between alcohol consumption and cancer. PMID- 27720395 TI - Fenofibrate Inhibits Cytochrome P450 Epoxygenase 2C Activity to Suppress Pathological Ocular Angiogenesis. AB - Neovascular eye diseases including retinopathy of prematurity, diabetic retinopathy and age-related-macular-degeneration are major causes of blindness. Fenofibrate treatment in type 2 diabetes patients reduces progression of diabetic retinopathy independent of its peroxisome proliferator-activated receptor (PPAR)alpha agonist lipid lowering effect. The mechanism is unknown. Fenofibrate binds to and inhibits cytochrome P450 epoxygenase (CYP)2C with higher affinity than to PPARalpha. CYP2C metabolizes omega-3 long-chain polyunsaturated fatty acids (LCPUFAs). While omega-3 LCPUFA products from other metabolizing pathways decrease retinal and choroidal neovascularization, CYP2C products of both omega-3 and omega-6 LCPUFAs promote angiogenesis. We hypothesized that fenofibrate inhibits retinopathy by reducing CYP2C omega-3 LCPUFA (and omega-6 LCPUFA) pro angiogenic metabolites. Fenofibrate reduced retinal and choroidal neovascularization in PPARalpha-/-mice and augmented omega-3 LCPUFA protection via CYP2C inhibition. Fenofibrate suppressed retinal and choroidal neovascularization in mice overexpressing human CYP2C8 in endothelial cells and reduced plasma levels of the pro-angiogenic omega-3 LCPUFA CYP2C8 product, 19,20 epoxydocosapentaenoic acid. 19,20-epoxydocosapentaenoic acid reversed fenofibrate induced suppression of angiogenesis ex vivo and suppression of endothelial cell functions in vitro. In summary fenofibrate suppressed retinal and choroidal neovascularization via CYP2C inhibition as well as by acting as an agonist of PPARalpha. Fenofibrate augmented the overall protective effects of omega-3 LCPUFAs on neovascular eye diseases. PMID- 27720398 TI - Comparative genome analysis of two Streptococcus phocae subspecies provides novel insights into pathogenicity. AB - Streptococcus phocae is a beta-hemolytic, Gram-positive bacterium that was first isolated in Norway from clinical specimens of harbor seal (Phoca vitulina) affected by pneumonia or respiratory infection, and in 2005, this bacterium was identified from disease outbreaks at an Atlantic salmon farm. A recent comparative polyphasic study reclassified Streptococcus phocae as subsp. phocae and subsp. salmonis, and there are currently two S. phocae NCBI sequencing projects for the type strains ATCC 51973T and C-4T. The present study compared these genome sequences to determine shared properties between the pathogenic mammalian and fish S. phocae subspecies. Both subspecies presented genomic islands, prophages, CRISPRs, and multiple gene activator and RofA regulator regions that could play key roles in the pathogenesis of streptococcal species. Likewise, proteins possibly influencing immune system evasion and virulence strategies were identified in both genomes, including Streptokinases, Streptolysin S, IgG endopeptidase, Fibronectin binding proteins, Daunorubicin, and Penicillin resistance proteins. Comparative differences in phage, non-phage, and genomic island sequences may form the genetic basis for the virulence, pathogenicity, and ability of S. phocae subsp. salmonis to infect and cause disease in Atlantic salmon, in contrast to S. phocae subsp. phocae. This comparative genomic study between two S. phocae subsp. provides novel insights into virulence factors and pathogenicity, offering important information that will facilitate the development of preventive and treatment measures against this pathogen.

AB - The human gut microbiome is a complex ecosystem of fundamental importance to human health. Our increased understanding of gut microbial composition and functional interactions in health and disease states has spurred research efforts examining the gut microbiome as a valuable target for therapeutic intervention. This review provides updated insight into the state of the gut microbiome in recurrent Clostridium difficile infection (CDI), ulcerative colitis (UC), and obesity while addressing the rationale for the modulation of the gut microbiome using fecal microbiota transplant (FMT)-based therapies. Current microbiome-based therapeutics in pre-clinical or clinical development are discussed. We end by putting this within the context of the current regulatory framework surrounding FMT and related therapies. PMID- 27720399 TI - Becoming a sexual being: The 'elephant in the room' of adolescent brain development. AB - The onset of adolescence is a time of profound changes in motivation, cognition, behavior, and social relationships. Existing neurodevelopmental models have integrated our current understanding of adolescent brain development; however, there has been surprisingly little focus on the importance of adolescence as a sensitive period for romantic and sexual development. As young people enter adolescence, one of their primary tasks is to gain knowledge and experience that will allow them to take on the social roles of adults, including engaging in romantic and sexual relationships. By reviewing the relevant human and animal neurodevelopmental literature, this paper highlights how we should move beyond thinking of puberty as simply a set of somatic changes that are critical for physical reproductive maturation. Rather, puberty also involves a set of neurobiological changes that are critical for the social, emotional, and cognitive maturation necessary for reproductive success. The primary goal of this paper is to broaden the research base and dialogue about adolescent romantic and sexual development, in hopes of advancing understanding of sex and romance as important developmental dimensions of health and well-being in adolescence. PMID- 27720400 TI - Evaluation of quail and turkey egg yolk for cryopreservation of Nili-Ravi buffalo bull semen. AB - Egg yolk is used as a cryoprotectant for semen in different mammalian species including buffalo. Egg yolk from different sources may affect freezability of buffalo bull semen. Quail egg yolk (QEY) and turkey egg yolk (TEY) in Tris-citric acid extender was evaluated for post-thaw quality and in vivo fertility rate of cryopreserved buffalo bull semen. Ejaculates were collected on weekly basis from six Nili-Ravi buffalo bulls (12 ejaculates/bull) for a period of 6 weeks and diluted at 37 degrees C with tris-citric egg yolk extender (50 * 106 motile spermatozoa mL-1) containing different levels of QEY or TEY (5%, 10%, 15%, and 20%) or 20% chicken egg yolk (CEY; controls) and cryopreserved. Percent post-thaw sperm motility (48.3 +/- 3.8), plasma membrane integrity (67.9 +/- 5.3), live/dead ratio (68.2 +/- 5.0), and viability (50.5 +/- 3.7) were recorded higher (P < 0.05) in extender containing 5% QEY compared with control. However, TEY at 10% in extender improved (P < 0.05) the post-thaw sperm motility (57.5 +/- 5.2), plasma membrane integrity (53.5 +/- 4.5), livability (75.3 +/- 6.0), and viability (73.5 +/- 6.5) compared with higher concentrations of TEY and controls (20% CEY). The chromatin damage (2.0 +/- 0.9) and intracellular enzymes, glutamic oxaloacetic transaminase (24.8 +/- 3.5) and lactic dehydrogenase (77.7 +/- 4.5), release were lower (P < 0.05) in extender containing 10% TEY compared with the controls. Invivo fertility was compared after artificial insemination with semen from two buffalo bulls that was cryopreserved in extenders containing 5% QEY, 10% TEY, or 20% CEY. A total of 600 inseminations (200 inseminations per extender) were recorded; the overall fertility rate was significantly higher (P < 0.05) with semen cryopreserved in extender containing 5% QEY (57.5 vs. 42%) and 10% TEY (57.5 vs. 42%). compared with 20% chiken egg yolk. In conclusion, QEY at 5% and TEY at 10% offers advantages over 20% CEY in terms of in vitro post-thaw semen quality and in vivo fertility of buffalo. PMID- 27720401 TI - Schizophrenia and metabolic dysregulation: shared roots? PMID- 27720402 TI - The association between first-episode psychosis and abnormal glycaemic control: systematic review and meta-analysis. AB - BACKGROUND: Schizophrenia might share intrinsic inflammatory disease pathways with type 2 diabetes. We aimed to assess whether first-episode psychosis, which could be described as developing schizophrenia, is associated with prediabetic markers, or developing diabetes, to determine whether intrinsic disease links could cause the disorders to develop in unison. We hypothesised that biochemical measures of prediabetic states would be more common in antipsychotic naive patients with first-episode psychosis than in healthy matched controls. METHODS: For this systematic review and meta-analysis, using PRISMA criteria, we searched Embase, MEDLINE, PsycINFO, Web of Science, and Google Scholar for clinical studies published between database inception and Jan 6, 2016. We assessed case control studies with biochemical assessment of prediabetic states in patients with first-episode psychosis alongside matched controls. We sought data at the summary estimate level. Several measurements were used to test for prediabetes, including fasting plasma glucose, insulin resistance (measured by the Homeostatic Model Assessment), and impaired glucose tolerance. We calculated standardised mean differences for each outcome. We used the inverse variance method, for which the weight given to each study was the inverse of the variance of the effect estimate. For dichotomous outcomes, we entered the number of events and number in each group into RevMan 5.3 and used the Mantel-Haenszel method to pool studies. FINDINGS: We identified 1436 studies, of which 12 were included in final analysis, including 1137 participants. Pooled analyses found first-episode psychosis to be related to insulin resistance (mean difference 0.30 [95% CI 0.18 to 0.42]), impaired glucose tolerance (mean difference 1.31 [0.37 to 2.25]), and the number of patients with impaired glucose tolerance (odds ratio 5.44 [2.63 to 11.27]), but not fasting plasma glucose (mean difference 0.03 mmol/L [-0.04 to 0.09]). INTERPRETATION: Our findings suggest a potential link between prediabetic markers, in particular impaired glucose tolerance and insulin resistance, and first-episode psychosis. However, we cannot establish causality, and the studies contributing to this review were at some risk of bias. Nevertheless, the findings might help to explain the increased prevalence of type 2 diabetes in patients with schizophrenia and could have implications for the management of patients with schizophrenia. FUNDING: None. PMID- 27720403 TI - Effect of daily calcitriol supplementation with and without calcium on disease regression in non-alcoholic fatty liver patients following an energy-restricted diet: Randomized, controlled, double-blind trial. AB - BACKGROUND & AIMS: Despite evidence for beneficial effects of vitamin D, to our knowledge, no study has compared the effects of calcium supplementation with vitamin D on non-alcoholic fatty liver disease (NAFLD) regression during a hypo energetic program. We compared the effect of the vitamin D supplementation with and without calcium on anthropometric measures and biochemical parameters in NAFLD patients during a weight-loss program. METHODS: A 12-week, randomized, controlled, double-blind trial was conducted in 120 NAFLD patients randomly assigned to receive 25 MUg calcitriol (n = 37), 500 mg calcium carbonate + 25 MUg calcitriol (n = 37), or placebo (n = 36) every day with their lunch meals while following a weight-loss program. RESULTS: Weight, BMI and fat mass reduction were significant in each group after 12 wk of intervention (p < 0.001), but differences among the groups was not significant after 12 wk of the study, adjusted to the baseline measurements. Significant reduction in fasting plasma glucose (FPG), insulin, insulin resistance (by HOMA-IR) and TG concentrations and an increase in HDL.C was seen over the 12 wk of study in each group (p < 0.001). Adjusting to the baseline measurements, there was significant difference in FPG (p < 0.001), HOMA-IR (p < 0.001), serum insulin (p = 0.01), TG (p = 0.01) and HDL.C (p < 0.001) among the groups after 12 wk of the study. The calcium plus calcitriol group showed a significant decrease in ALT and FPG and increase in HDL.C level compared with the calcitriol group, adjusted to the baseline measures (p < 0.001). CONCLUSIONS: Our results suggest that calcium plus calcitriol supplementation for 12 weeks may be potentially effective for biochemical parameters in NAFLD patients. Further additional larger controlled trials are needed to confirm these findings. REGISTRATION: Registered under ClinicalTrials.gov Identifier no. IRCT201408312709N29. PMID- 27720404 TI - Video Coaching as an Efficient Teaching Method for Surgical Residents-A Randomized Controlled Trial. AB - BACKGROUND: As surgical training is evolving and operative exposure is decreasing, new, effective, and experiential learning methods are needed to ensure surgical competency and patient safety. Video coaching is an emerging concept in surgery that needs further investigation. DESIGN: In this randomized controlled trial conducted at a single teaching hospital, participating residents were filmed performing a side-to-side intestinal anastomosis on cadaveric dog bowel for baseline assessment. The Surgical Video Coaching (SVC) group then participated in a one-on-one video playback coaching and debriefing session with a surgeon, during which constructive feedback was given. The control group went on with their normal clinical duties without coaching or debriefing. All participants were filmed making a second intestinal anastomosis. This was compared to their first anastomosis using a 7-category-validated technical skill global rating scale, the Objective Structured Assessment of Technical Skills. A single independent surgeon who did not participate in coaching or debriefing to the SVC group reviewed all videos. A satisfaction survey was then sent to the residents in the coaching group. SETTING: Department of Surgery, HopitalMaisonneuve-Rosemont, tertiary teaching hospital affiliated to the University of Montreal, Canada. PARTICIPANTS: General surgery residents from University of Montreal were recruited to take part in this trial. A total of 28 residents were randomized and completed the study. RESULTS: After intervention, the SVC group (n = 14) significantly increased their Objective Structured Assessment of Technical Skills score (mean of differences 3.36, [1.09-5.63], p = 0.007) when compared to the control group (n = 14) (mean of differences 0.29, p = 0.759). All residents agreed or strongly agreed that video coaching was a time efficient teaching method. CONCLUSIONS: Video coaching is an effective and efficient teaching intervention to improve surgical residents' technical skills. PMID- 27720405 TI - Construct Validity, Assessment of the Learning Curve, and Experience of Using a Low-Cost Arthroscopic Surgical Simulator. AB - OBJECTIVE: We have developed a low-cost, portable shoulder simulator designed to train basic arthroscopic skills. This study aimed to establish the construct validity of the simulator by determining which parameters discriminated between experience levels and to assess the experience of using the simulator. DESIGN: Participants were given an introductory presentation and an untimed practice run of a 6-step triangulation task using hooks and rubber bands. A total of 6 consecutive attempts at the task were timed, and the number of times the participant looked at their hands during the task was recorded. Participants then completed a questionnaire on their experience of using the simulator. SETTING: St George's Hospital, London and the South West London Elective Orthopaedic Centre, Surrey. PARTICIPANTS: Medical students, trainee doctors and surgeons, and consultant surgeons were approached to use the simulator. Participation was voluntary and nonincentivized. In total, 7 orthopedic consultants, 12 trainee doctors (ranging from foundation year 1 to clinical fellow post-Certificate of Completion of Training), and 9 medical students were recruited. RESULTS: The average time for medical students to complete the task was 161 seconds, compared to 118 seconds for trainees, and 84 seconds for consultants. The average fastest time for medical students was 105 seconds, 73 seconds for trainees, and 52 seconds for consultants. Students were significantly slower than trainees (p = 0.026) and consultants (p = 0.001). However, times did not differ significantly between trainees and consultants. Consultants looked at their hands 0.7 times on average during the task compared with 2.8 and 3.4 times for trainees and students, respectively. More than 95% of participants found the exercise interesting and agreed or strongly agreed that the simulator was easy to use, easily portable, and well designed and constructed. DISCUSSION: This study has established construct validity of the simulator by demonstrating the ability to distinguish between surgical experience levels. The learning curve shows improvement in individuals with or without arthroscopic or surgical experience. Simulation is becoming increasingly important in the training of medical students and surgical trainees; this study has established that low-cost portable arthroscopic box trainers may play a significant role.

PMID- 27720409 TI - Fourth-Grade Children's Reporting Accuracy for Amounts Eaten at School-Provided Meals: Insight from a Reporting-Error-Sensitive Analytic Approach Applied to Validation Study Data. AB - BACKGROUND: Validation studies that have directly assessed reporting accuracy for amounts eaten have provided results in various ways. OBJECTIVE: To analyze amount categories of a reporting-error-sensitive approach for insight concerning reporting accuracy for amounts eaten. DESIGN: For a cross-sectional validation study, children were observed eating school-provided breakfast and lunch, and randomized to one of eight 24-hour recall conditions (two retention intervals [short and long] crossed with four prompts [forward, meal name, open, and reverse]). PARTICIPANTS/SETTING: Data collected during 3 school years (2011-2012 to 2013-2014) on 455 children from 10 schools (four districts) in a southern US state. MAIN OUTCOME MEASURES: Items were classified as matches (observed and reported), omissions (observed but unreported), or intrusions (unobserved but reported). Within amount categories (matches [corresponding, overreported, and underreported], intrusions [overreported], and omissions [underreported]), item amounts were converted to kilocalories. STATISTICAL ANALYSES PERFORMED: A multilevel model was fit with food-level explanatory variables (amount category and meal) and child-level explanatory variables (retention interval, prompt, sex, and race/ethnicity). To investigate inaccuracy differences, t tests on three contrasts were performed. RESULTS: Inaccuracy differed by amount category (P<0.001; in order from largest to smallest: omission, intrusion, underreported match, and overreported match), meal (P=0.01; larger for breakfast), retention interval (P=0.003; larger for long), sex (P=0.004; larger for boys), race/ethnicity (P=0.045; largest for non-Hispanic whites), and amount category*meal interaction (P=0.046). Overreported amounts were larger for intrusions than overreported matches (P<0.0001). Underreported amounts were larger for omissions than underreported matches (P<0.0001). Overall underreported amounts (from omissions and underreported matches) exceeded overall overreported amounts (from intrusions and overreported matches) (P<0.003). CONCLUSIONS: Amount categories provide a standard way to analyze validation study data on reporting accuracy for amounts eaten, and compare results across studies. Multilevel analytic models reflecting the data structure are recommended for inference. To enhance reporting accuracy for amounts eaten, focus on increasing reports of correct items, thereby yielding more matches with fewer intrusions and omissions.

AB - Sarcoidosis is an inflammatory disease with unknown cause characterized by non caseating granuloma formations. It may present with bilateral hilar lymphadenopathy, skin lesions, eye and musculoskeletal system involvement. Hypercalcemia and hypercalciuria are important electrolyte imbalances resulting from sarcoidosis and sometimes they may cause nephrolitiasis and kidney failure. Hyponatremia, although being quite rare, has been found in some patients with sarcoidosis. Herein, we have reported a patient with neurosarcoidosis who presented with hyponatremia and responded well to corticosteroid treatment. PMID- 27720412 TI - Suture spanning augmentation of single-row rotator cuff repair: a biomechanical analysis. AB - BACKGROUND: This in vitro study evaluated the biomechanical benefit of adding spanning sutures to single-row rotator cuff repair. METHODS: Mechanical testing was performed to evaluate 9 pairs of cadaveric shoulders with complete rotator cuff repairs, with a single-row technique used on one side and the suture spanning technique on the other. The spanning technique included sutures from 2 lateral anchors securing tendon near the musculotendinous junction, spanning the same anchor placement from single-row repair. The supraspinatus muscle was loaded to 100 N at 0.25 Hz for 100 cycles, followed by a ramp to failure. Markers and a video tracking system measured anterior and posterior gap formation across the repair at 25-cycle intervals. The force at which the stiffness decreased by 50% and 75% was determined. Data were compared using paired t-tests. RESULTS: One single-row repair failed at <25 cycles. Both anterior and posterior gap distances tended to be 1 to 2 mm larger for the single-row repairs than for the suture spanning technique. The difference was statistically significant at all cycles for the posterior gap formation (P <= .02). The trends were not significant for the anterior gap (P >= .13). The loads at which the stiffness decreased by 50% and 75% did not differ significantly between the 2 types of repair (P >= .10). CONCLUSIONS: The suture spanning technique primarily improved posterior gap formation. Decreased posterior gap formation could reduce failure rates for rotator cuff repair. PMID- 27720413 TI - Neer Award 2015: Analysis of cytokine profiles in the diagnosis of periprosthetic joint infections of the shoulder. AB - BACKGROUND: Periprosthetic joint infection (PJI) after shoulder arthroplasty can present a diagnostic and therapeutic challenge. This study evaluated the diagnostic utility of broader synovial fluid cytokine analysis for identifying PJI in patients undergoing revision shoulder arthroplasty. METHODS: Synovial fluid levels of 9 cytokines (interleukin [IL] 6, granulocyte-macrophage colony stimulating factor, IL-1beta, IL-12, IL-2, IL-8, interferon-gamma, IL-10, and tumor necrosis factor-alpha) were measured in 75 cases of revision shoulder arthroplasty with a multiplex immunoassay. Cases were classified into infection categories and groups based on objective perioperative findings. Differences in cytokine levels among infection groups were evaluated. Receiver operating characteristic curves were used to assess the diagnostic utility of the individual synovial fluid cytokines and combinations of cytokines in determining infection status. RESULTS: Synovial IL-6, granulocyte-macrophage colony stimulating factor, interferon-gamma, IL-1beta, IL-2, IL-8, and IL-10 were significantly elevated in cases of revision shoulder arthroplasty classified as infected. Individually, IL-6, IL-1beta, IL-8, and IL-10 showed the best combination of sensitivity and specificity for predicting infection, and a combined cytokine model consisting of IL-6, tumor necrosis factor-alpha, and IL-2 showed better diagnostic test characteristics than any cytokine alone, with sensitivity of 0.80, specificity of 0.93,, positive and negative predictive values of 0.87 and 0.89, and positive and negative likelihood ratios of 12.0 and 0.21. CONCLUSIONS: Individual and combined synovial fluid cytokine analysis were both more effective than routine perioperative testing, such as serum erythrocyte sedimentation rate and C-reactive protein, in the diagnosis of PJI of the shoulder. Once validated, combined synovial fluid cytokine analysis could be used as a predictive tool to determine the probability of PJI in patients undergoing revision shoulder arthroplasty and better guide treatment. PMID- 27720414 TI - Rotator cuff surgery in patients older than 75 years with large and massive tears. AB - BACKGROUND: The purpose of this study was to evaluate whether rotator cuff repair improves subjective and functional outcomes in patients aged >=75 years. METHODS: From May 2005 to March 2013, 121 elderly patients who underwent rotator cuff repair for large and massive rotator cuff tears were evaluated retrospectively. Patients with an American Society of Anesthesiologists physical status classification system grade >=4 were excluded. The patients were evaluated using visual analog scales, subjective satisfaction surveys, American Shoulder and Elbow Surgeons scores, and Constant scores. The Katz index of activity of daily living (ADL) and functional independence measure motor score were used to evaluate ADLs. Postoperative magnetic resonance imaging (MRI) was performed to investigate the structural integrity of repaired cuffs. RESULTS: In total, 64 patients were enrolled in the study; 80% were satisfied with their results. Visual analog scale scores improved from 6.4 to 2.3, American Shoulder and Elbow Surgeons scores from 42 to 84, and Constant scores from 42 to 76. Katz ADL scores improved from 3.4 to 5.0. Functional independence measure motor score improved from 22 to 51. Of the 64 patients, 46 underwent MRI 1 year postoperatively. Follow-up MRI revealed retears in 26% of patients. All patients with retears had improved subjective outcomes and functional scores. No patients died or experienced complications requiring intensive care or extended hospitalization. CONCLUSIONS: Surgical treatment for large to massive rotator cuff tears in elderly patients with American Society of Anesthesiologists grade <4 provides good functional outcomes without morbidity, even in those with retears. PMID- 27720415 TI - Subscapularis tendon loading during activities of daily living. AB - BACKGROUND: The purpose of this study was to determine the relative amount of load that is transmitted through the superior portion of the subscapularis during activities of daily living as compared with the load that is transmitted through the middle and inferior portions in a normal shoulder and in a shoulder with a supraspinatus tear. METHODS: By use of the Newcastle shoulder model, the subscapularis was modeled with 3 lines of action encircling the humeral head. The load was measured in the entire subscapularis, and the percentage of this load in each of the 3 tendinous bands was calculated. Subsequently, a supraspinatus tear was simulated, and the forces generated by the subscapularis and glenohumeral joint contact forces were measured. RESULTS: The maximum force produced by the entire subscapularis muscle for the various activities ranged from 3 to 43 N. Load sharing between the 3 subscapularis bands showed that the superior band bore the largest percentage of the total load of the muscle (95% +/- 2%). The load in the subscapularis, particularly in the superior band, increased significantly when a supraspinatus tear was simulated (P < .0001). CONCLUSION: The superior band of the subscapularis tendon bears the highest percentage of load compared with the middle or inferior band. The load in the subscapularis increased significantly in the presence of a simulated supraspinatus tear. Because a disproportionate amount of force is transmitted through the superior subscapularis, more clinical research is warranted to determine whether tears in this region should be routinely repaired.

PMID- 27720417 TI - Maintaining a clinical weight loss after intensive lifestyle intervention is the key to cardiometabolic health. AB - OBJECTIVE: Intensive lifestyle interventions (ILI) are criticised for ineffective obesity treatment because weight loss over time is modest and thus of limited clinical relevance. However, a subgroup (5-30%) maintains a clinical weight loss >10%, but it is not clear if cardiometabolic health follows this pattern. The aim was to study the effect of different magnitudes of weight loss maintenance after ILI on cardiometabolic health. METHODS: Eighty out of 2420 former participants (age: 36+/-1, BMI: 38+/-1, (means +/-SE)) in an 11-12-week ILI were recruited into 3 groups; clinical weight loss maintenance (>10% weight loss), moderate maintenance (1-10%), and weight regain based on weight loss at follow-up (5.3+/ 0.4years). Weight loss during the ILI was achieved by increased physical activity and hypo-caloric diet. Dual X-ray Absorptiometry, blood sample, skeletal muscle biopsy and VO2max test were used to determine cardiometabolic health at follow up. RESULTS: At follow-up, the clinical weight loss maintenance group scored better in the following variables compared to the other groups: BMI (31+/-1, 33+/ 2, 43+/-2kg/m2), composition (34+/-2, 40+/-1, 49+/-1% fat), visceral adipose tissue (0.8+/-0.2, 1.7+/-0.5, 2.4+/-0.4kg), plasma triglycerides (0.8+/-0.2, 1.3+/-0.4, 1.6+/-0.3mmol/L), plasma glucose (4.9+/-0.1, 5.9+/-0.4, 5.9+/ 0.1mmol/L), Hb1Ac (5.1+/-0.0, 5.6+/-0.2, 5.8+/-0.2%), protein content in skeletal muscle of GLUT4 (1.5+/-0.2, 0.9+/-0.1, 1.0+/-0.1 AU) and hexokinase II (1.6+/ 0.2, 1.0+/-0.2, 0.7+/-0.1 AU), citrate synthase activity (155+/-6, 130+/-5, 113+/ 5MUmol/g/min) and VO2max (49+/-1, 43+/-1, 41+/-1mL/min/FFM) (p<0.05). CONCLUSION: Cardiometabolic health is better in participants who have maintained >10% weight loss compared to moderate weight loss and weight regain.

PMID- 27720418 TI - A comparative study of the metabolic effects of LSG and LRYGB in Chinese diabetes patients with BMI<35 kg/m2. AB - BACKGROUND: The metabolic effects of laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in type 2 diabetes (T2D) patients who do not meet National Institutes of Health indications has not been well studied. OBJECTIVES: To compare the effectiveness of LSG and LRYGB in Chinese T2D patients with body mass index (BMI)<35 kg/m2. SETTING: University hospital, China. METHODS: A nonrandomized cohort of patients who underwent LRYGB (n = 64) and LSG (n = 19) were followed up for 3 years and the outcomes (weight loss and remission of diabetes and other metabolic parameters) were compared. Univariate and multivariate analyses were applied to find associated parameters of T2D remission. RESULTS: In total, 5 patients (6%) were lost to follow-up. No significant differences in mean percentage of excess weight loss and BMI were observed between the 2 groups at 2 years. At 3-year follow-up, the LRYGB group had significantly higher percentage of excess weight loss and lower BMI. The total (complete and partial) remission rate achieved with both bariatric procedures was 75.9% at 1 year and 56.4% at 3 years. Surgical safety, diabetes remission, and remission of other obesity-related co-morbidities were comparable between the 2 groups. Patients who achieved complete or partial remission had lower fasting plasma glucose, lower plasma glucose at 2 hours, lower glycated hemoglobin, and higher fasting C peptide than the other patients at baseline. High recurrence rates of hypertension and hyperuricemia were observed at 3 years postoperation. CONCLUSIONS: Both LSG and LRYGB are safe and effective bariatric procedures for T2D in this Chinese population with diabetes and BMI<35 kg/m2. PMID- 27720420 TI - Perioperative thromboprophylaxis in severely obese patients undergoing bariatric surgery: insights from a French national survey. AB - BACKGROUND: Venous thromboembolism (VTE) is a leading cause of death in obese patients undergoing bariatric surgery (BS), but there is neither consensus nor high-level guidelines yet on VTE prophylaxis in this specific population. OBJECTIVE: We aimed to evaluate patterns of BS perioperative thromboprophylaxis practices. SETTING: French obesity specialized care centers (CSO), which are tertiary care referral hospitals for the most severe cases of obesity METHODS: A detailed questionnaire survey (11 opened, 15 closed questions) investigating their prophylactic schemes of anticoagulation (molecule, dose, weight-adjustment, duration, associated measures, follow-up) was sent to the 37 CSO. RESULTS: Completion rate was 92%. Over 90% of respondents indicated using low molecular weight heparin. Enoxaparin was the most commonly used molecule (89%), twice daily (71%), started mostly 6 hours after BS (74%), whereas fondaparinux (9%), dalteparin (6%), and tinzaparin (6%) were less often prescribed. Dosing varied significantly according to centers from 4000 to 12,000 IU/d, with the most commonly used dose being 8000 IU once daily, 83%, as well as treatment duration (1 week, 9%; 3 weeks, 47%). Half CSO adjusted low molecular weight heparin dose to weight. Biological monitoring was performed in 88%. Only 1 center followed systematically anti-Xa activity. Associated measures such as elastic stoking or intermittent pneumatic compression were used in 32% and 26%, respectively, and both were used in 39%. CONCLUSION: This study finds significant discrepancies in thromboprophylaxis practices in obese patients undergoing BS, particularly with respect to treatment duration and dose adjustment, highlighting the urgent need for improved implementation of existing clinical practice guidelines in this VTE high-risk population. PMID- 27720421 TI - Experimental evaluation of chromatographic performance of capillary and microfluidic columns with linear or curved channels. AB - We prepared 0.3 or 0.15mm i.d. columns from both fused silica capillaries and planar titanium wafers with machined grooves. Both types of devices were packed with sub-two micron C18 sorbent. Chromatographic efficiency and peak capacity were tested using LC instruments with low extra column dispersion (300nL2 or 30nL2 for 0.3 or 0.15mm i.d. columns, respectively). Micro column testing in gradient mode was less affected by extra column (pre-column) dispersion. To exploit this feature we developed a method for estimation of column efficiency from gradient analysis using the theoretical relationship (Pc-1)=N0.5*const. The validity of this relationship was experimentally verified using 2.1mm i.d. and 0.3mm i.d. columns. The (Pc-1) versus N relationship was experimentally determined with straight columns, which in turn was employed for the estimation of microfluidic column efficiency. Microfluidic devices with serpentine channels exhibited lower isocratic efficiency than straight capillary columns, but the loss of peak capacity was less significant. The loss chromatographic efficiency due to zone dispersion in serpentine microfluidic channels was more apparent for 0.3 than 0.15mm i.d. devices. Gradient performance of 0.15*100mm microfluidic columns was comparable to state-of-the-art 2.1*100mm columns packed with the same sorbent. PMID- 27720422 TI - Hollow molecular imprinted polymers towards rapid, effective and selective extraction of caffeic acid from fruits. AB - Rapid and selective extraction and enrichment of trace bioactive analytes from complex matrices were of significant importance for efficient and accurate quantification. Here, novel hollow molecular imprinted polymers (HMIPs) were prepared using caffeic acid (CA) as template, 4-vinylpyridine (4-VP) as functional monomer, and Fe3O4@SiO2 as sacrificial support. Fourier transform infrared spectrometer (FT-IR), transmission electron microscopy (TEM), nitrogen adsorption and thermo-gravimetric analysis (TGA) were used to verify the successful synthesis of HMIPs. Hollow structure with large surface area (325.8m2/g) made most recognition sites locate on the surface of HMIPs, resulting in high binding capacity (21.10mg/g) and fast kinetic binding (35min) in comparison with magnetic MIPs (MMIPs) and solid MIPs. The equilibrium data fitted well to Freundlich equation and the adsorption process could be described by pseudo-second order model. The selectivity performance of HMIPs was favorable. Finally, HMIPs were successfully used as adsorbent to rapidly and selectively extract and enrich CA from fruits with a relatively satisfactory recovery (85.6 103.5%). Coupling with high-performance liquid chromatography (HPLC), the content of CA in four kinds of fruits (kiwifruit, apple, papaya and waxberry) was determined as less than 1.0MUg/g fresh fruit. Results indicated the superiority of HMIPs in the selective extraction of target compound from complex matrices. PMID- 27720423 TI - Filler characteristics of modern dental resin composites and their influence on physico-mechanical properties. AB - OBJECTIVE: The mechanical properties of dental resin-based composites (RBCs) are highly dependent on filler characteristics (size, content, geometry, composition). Most current commercial materials are marketed as "nanohybrids" (i.e. filler size <1MUm). In the present study, filler characteristics of a selection of RBCs were described, aiming at identifying correlations with physico mechanical properties and testing the relevance of the current classification. METHODS: Micron/sub-micron particles (> or <500nm) were isolated from 17 commercial RBCs and analyzed by laser diffractrometry and/or electron microscopy. Filler and silane content were evaluated by thermogravimetric analysis and a sedimentation technique. The flexural modulus (Eflex) and strength (sigmaflex) and micro-hardness were determined by three-point bending or with a Vickers indenter, respectively. Sorption was also determined. All experiments were carried out after one week of incubation in water or 75/25 ethanol/water. RESULTS: Average size for micron-sized fillers was almost always higher than 1MUm. Ranges for mechanical properties were: 3.775wt%) were associated with the highest mechanical properties (Eflex and sigmaflex>12GPa and 130MPa, respectively) and lowest solvent sorption (~0.3%). SIGNIFICANCE: Mechanical properties and filler characteristics significantly vary among modern RBCs and the current classification does not accurately illustrate either. Further, the chemical stability of RBCs differed, highlighting differences in resin and silane composition. Since Eflex and sorption were well correlated to the filler content, a simple and unambiguous classification based on such characteristic is suggested, with three levels (ultra-low fill, low-fill and compact resin composites). PMID- 27720424 TI - The network substrate of confabulatory tendencies in Alzheimer's disease. AB - Confabulatory phenomena are rare in the early stage of Alzheimer's disease (AD), are often provoked and are triggered by questions or in response to neuropsychological testing. In this retrospective study functional connectivity alterations were investigated for the first time in a group of patients with early AD who had shown evidence of verbal and non-verbal confabulatory tendencies. Resting-state functional magnetic resonance imaging (fMRI) scans of 18 confabulating patients were compared with those of 18 non confabulators. The finding showed that confabulators had decreased connectivity between a seed region in the right inferolateral frontal cortex and right mediotemporal and insular regions, and increased connectivity with frontal areas and a homologous region on the left. The seed control region in the left inferolateral frontal cortex showed increased connectivity with midline frontal and anterior cingulate regions, while a decrease was found in temporal areas. Confabulatory tendencies appear in early AD as a result of disconnection between crucial computational hubs in frontal and mediotemporal regions. This disconnection is coupled with the presence of up-regulation of frontal activity, and especially of midline and anterior cingulate regions, which might disrupt efficient output monitoring in confabulators. PMID- 27720425 TI - Sperm head shaping in ratites: New insights, yet more questions. AB - Head shaping in mammalian sperm is regulated by a number of factors including acrosome formation, nuclear condensation and the action of the microtubular manchette. A role has also been suggested for the attendant Sertoli cells and the perinuclear theca (PT). In comparison, relatively little information is available on this topic in birds and the presence of a PT per se has not been described in this vertebrate order. This study revealed that a similar combination of factors contributed to head shaping in the ostrich, emu and rhea, although the Sertoli cells seem to play a limited role in ratites. A fibro-granular structure analogous to the mammalian PT was identified, consisting of sub- and post acrosomal components. The latter was characterized by stage-specific finger-like projections that appeared to emanate from the cytoplasmic face of the nuclear envelope. They were particularly obvious beneath the base of the acrosome, and closely aligned, but not connected to, the manchette microtubules. During the final stages of chromatin condensation and elongation of the sperm head the projections abruptly disappeared. They appear to play a role in stabilizing the shape of the sperm head during the caudal translocation of the spermatid cytoplasm. PMID- 27720426 TI - Rho GTPases operating at the Golgi complex: Implications for membrane traffic and cancer biology. AB - The Golgi complex is the central unit of the secretory pathway, modifying, processing and sorting proteins and lipids to their correct cellular localisation. Changes to proteins at the Golgi complex can have deleterious effects on the function of this organelle, impeding trafficking routes through it, potentially resulting in disease. It is emerging that several Rho GTPase proteins, namely Cdc42, RhoBTB3, RhoA and RhoD are at least in part localised to the Golgi complex, and a number of studies have shown that dysregulation of their levels or activity can be associated with cellular changes which ultimately drive cancer progression. In this mini-review we highlight some of the recent work that explores links between form and function of the Golgi complex, Rho GTPases and cancer. PMID- 27720427 TI - Using trip diaries to mitigate route risk and risky driving behavior among older drivers. AB - To reduce exposure to risky and challenging driving situations and prolong mobility and independence, older drivers self-regulate their driving behavior. But self-regulation can be challenging because it depends on drivers' ability to assess their limitations. Studies using self-reports, survey data, and hazard and risk perception tests have shown that driving behavior feedback can help older drivers assess their limitations and adjust their driving behavior. But only limited work has been conducted in developing feedback technology interventions tailored to meet the information needs of older drivers, and the impact these interventions have in helping older drivers self-monitor their driving behavior and risk outcomes. The vehicles of 33 drivers 65 years and older were instrumented with OBD2 devices. Older drivers were provided access to customized web-based Trip Diaries that delivered post-trip feedback of the routes driven, low-risk route alternatives, and frequency of their risky driving behaviors. Data were recorded over four months, with baseline driving behavior collected for one month. Generalized linear mixed effects regression models assessed the effects of post-trip feedback on the route risk and driving behaviors of older drivers. Results showed that post-trip feedback reduced the estimated route risk of older drivers by 2.9% per week, and reduced their speeding frequency on average by 0.9% per week. Overall, the Trip Diary feedback reduced the expected crash rate from 1 in 6172 trips to 1 in 7173 trips, and the expected speeding frequency from 46% to 39%. Thus providing older drivers with tailored feedback of their driving behavior and crash risk could help them appropriately self-regulate their driving behavior, and improve their crash risk outcomes.

AB - BACKGROUND/PURPOSE: There is currently no unified view regarding whether liver transplantation or splenectomy should be performed for hypersplenism before liver transplantation in biliary atresia (BA) patients. We herein describe the efficacy of splenectomy before liver transplantation. METHODS: Splenectomy was performed in ten patients with hypersplenism associated with BA. We retrospectively reviewed their perioperative and postoperative courses, the number of leukocytes and thrombocytes, and the MELD score. RESULTS: The mean age was 17.5+/-7.0years (range 11-31years), and the male-to-female ratio was 1:1. The platelet and leukocyte levels increased after splenectomy and returned to normal levels one month postoperatively. The mean MELD score after splenectomy was significantly decreased after splenectomy: 10+/-2.1 vs 7.6+/-1.8. In particular, PT-INR improved. Five patients underwent liver transplantation because of hepatopulmonary syndrome and repeated bouts of cholangitis, whereas the remaining five patients did not undergo liver transplantation because of improvements in the liver function (the mean follow-up period was 56months). The postoperative complications included portal vein thrombosis and intestinal perforation, but the patient survival rates remained at 100%. CONCLUSION: After splenectomy, both pancytopenia and the liver function clearly improved. Splenectomy should therefore be a treatment option for patients with hypersplenism before liver transplantation. LEVEL OF EVIDENCE: Retrospective Comparative Study - Level III. PMID- 27720431 TI - [Common physiological basis for post-traumatic stress disorder and dependence to drugs of abuse: Implications for new therapeutic approaches]. AB - Post-traumatic stress disorder (PTSD) and addiction to drugs of abuse are two common diseases, showing high comorbidity rates. This review presents a number of evidence showing similarities between these two pathologies, especially the hyper responsiveness to environmental cues inducing a reactivation of the target memory leading either to re-experiencing (PTSD), or drug craving. Accordingly, PTSD and addiction to drug of abuse might by considered as memory pathologies, underlined by the same physiological process. We propose that these two pathologies rely on an uncoupling of the monoaminergic systems. According to this hypothesis, exposure to extreme conditions, either negative (trauma) or positive (drugs) induced a loss of the reciprocal control that one system usually exerts on the other monoaminergic system, resulting to an uncoupling between the noradrenergic and the serotonergic systems. Results obtained in our laboratory, using animal models of these pathologies, demonstrate that after a trauma, such as after repeated drug injections, rats developed both a behavioral sensitization (increases of the locomotion in response to a stimulation of the monoaminergic systems) and a pharmacological sensitization (increases of noradrenergic release within the prefrontal cortex). These results support our hypothesis and led us to propose new and innovative therapeutic approaches consisting either to induce a re-coupling of the monoaminergic systems, or to modify the pathological memories by using an emotional memory remodeling. Extremely encouraging results have already been obtained in rats and in humans, opening new and promising therapeutic avenues. PMID- 27720432 TI - Multidetector Computed Tomographic Angiography Imaging of Congenital Pulmonary Venous Anomalies: A Pictorial Review. AB - Congenital pulmonary venous anomalies are not uncommon that can occur either in isolation or in association with different forms of congenital heart disease. Clinical presentation of these anomalies may vary from the relatively benign single anomalous partial pulmonary venous return to life-threatening critical obstructed total anomalous pulmonary venous return. Accurate delineation of these anomalies and accompanied cardiovascular anomalies are crucial to guide decision making in these patients. Low-dose high-pitch dual-source 256-detector multidetector computed tomographic angiography is a fast and reliable imaging modality allowing comprehensive noninvasive anatomic imaging in neonates and children with congenital pulmonary venous anomalies with lower radiation doses and should be preferred for these patients after transthoracic echocardiography. PMID- 27720433 TI - Autumnalamide targeted proteins of the immunophilin family. AB - Previous works with autumnalamide reported that Store Operated Calcium (SOC) channels were blocked through mitochondrial modulation. In the present paper we studied the effect of autumnalamide on ionomycin Ca2+ fluxes. Thus, autumnalamide did not modify ionomycin-sensitive intracellular pools while the ionomycin induced Ca2+ influx was blocked with similar potency whether the incubation was done before or after ionomycin-sensitive pools depletion. Nevertheless, autumnalamide was not able to inhibit ionomycin-induced Ca2+ influx once the membrane channels were activated. Moreover, the compound efficiently inhibited flufenamic acid (FFA) Ca2+ release induced in this organelle but no the next influx. Since in previous work the effect of autumnalamide was inhibited by cyclosporine A (CsA), structures that target this drug were studied. Therefore, the affinity of autumnalamide for cyclophilin D (Cyp D) was examined. The KD obtained for Cyp D- autumnalamide was 1.51+/-1.399. Moreover, the KD for Cyp A- autumnalamide was calculated. The peptide had a similar order of Cyp A binding affinity than CsA (8.08+/-1.23 and 6.85+/-1.1MUM respectively). After testing autumnalamide-binding capacity for Cyp A, the activity of this compound on Cyp A pathway was tested. Thus, the effect on interleukin (IL)-2 release on activated T lymphocytes was checked. Autumnalamide was able to reduce IL-2 levels near to T cells in resting conditions. Next, the effect over calcineurin and NFATc1 was also evaluated. While CsA inhibits both calcineurin and NFATc1, autumnalamide did not produce any effect. From these results we can conclude that, autumnalamide targeted mitochondrion and prevent T-cells from IL-2 production through the modulation of SOC Ca2+ channels.

Six previously undescribed natural products, naringenin(3 -> 6")luteolin, naringenin(3 -> 6")chrysoeriol, liovil 4-O-beta-glucopyranoside, 2,6 dimethoxy cinnamic acid, (E)-4-(3-hydroxy-2,2-dimethylchroman-6-yl)but-3-en-2-one and (E)-4-(4-(((E)-4-hydroxy-3-methylbut-2-en-1-yl)oxy)phenyl)but-3-en-2-one, have been identified from fruits of N. ossifragum for the first time. In addition, the rare natural product 4-hydroxy-3-(3-methylbut-2-enyl)benzaldehyde and the five known compounds 4-hydroxycinnamic acid, quercetin 3,3'-dimethyl ether, quercetin 3,7-dimethyl ether, chrysoeriol 7-O-beta-glucopyranoside and the di-C-glycosylflavone isoschaftoside were all characterized for the first time from the fruits of N. ossifragum. The discovery of sufficient amounts of 4 hydroxy-3-(3-methylbut-2-enyl)benzaldehyde in fresh plant material of N. ossifragum to allow complete structure elucidation by NMR and HRMS supports the possibility that fungi associated with N. ossifragum may be able to produce enough toxins to play a significant role in the pathogenicity of N. ossifragum. 4 Hydroxy-3-(3-methylbut-2-enyl)benzaldehyde showed mild toxicity towards normal rat kidney (NRK) and more profound activity towards MOLM13 acute myeloid leukemia cells (IC50 = 430 MUM and 68 MUM, respectively). Naringenin(3 -> 6")luteolin had IC50 of 230 MUM towards NRK cells, and 115 MUM towards MOLM13 cells. Microscopic evaluation suggests that these two compounds induce cell death by different mechanisms. PMID- 27720438 TI - Surgery for postinfarction ventricular septal rupture.

AB - Recent studies show a substantial incidence of Pneumocystis jirovecii colonization and infection in patients with chronic inflammatory lung conditions. However, little is known about the impact of Pneumocystis upon the regulation of pulmonary immunity. We demonstrate here that Pneumocystis polarizes macrophages towards an alternatively activated macrophage-like phenotype. Genetically engineered mice that lack the ability to signal through IL-4 and IL-13 were used to show that Pneumocystis alternative macrophage activation is dependent upon signaling through these cytokines. To determine whether Pneumocystis-induced macrophage polarization would impact subsequent immune responses, we infected mice with Pneumocystis and then challenged them with Pseudomonas aeruginosa 14 days later. In co-infected animals, a higher proportion of macrophages in the alveolar and interstitial spaces expressed both classical and alternatively activated markers and produced the regulatory cytokines TGFbeta and IL-10, as well as higher arginase levels than in mice infected with P. aeruginosa alone. Our results suggest that Pneumocystis reprograms the overall macrophage repertoire in the lung to that of a more alternatively-activated setpoint, thereby altering subsequent immune responses. These data may help to explain the association between Pneumocystis infection and decline in pulmonary function. PMID- 27720436 TI - Supply chain management of health commodities for reducing global disease burden. AB - PURPOSE: Reducing global disease burden requires improving access to medicines, thus the need for efficient and effective supply chain management for medicines. The Nigerian government came up with new policies on Mega Drug Distribution Centres and National Drug Distribution Guidelines to improve access to quality medicines with pharmacists having a key role to play. However, pharmacists in Nigeria seem not to be aware and adequately equipped to handle the medicines supply chain. This article aimed at assessing the awareness and readiness of Nigerian pharmacists on supply chain management practices for improving access to medicines. METHODS: Pharmacists in Nigeria's Capital were randomly sampled. Semi structured questionnaires were administered. Descriptive statistics was used in data analysis. P values less than 0.05 were considered to be significant. RESULTS: 29.3%, 20.7% and 53.7% were not aware of supply chain management, National Drug Distribution Guidelines and Mega Drug Distribution Centres, respectively. 85.46% do not have a copy of the National Drug Distribution Guidelines. 78% were not aware that Mega Drug Distribution Centres are already operational. 35.4% have never been involved in any supply chain management practice. 69.5% often experience stock out of vital and essential medicines, of which 85.2% were in hospitals. 15.9% were successful in managing their facility's supply chains. 84.1% opined that pharmacists in Nigeria are not yet ready to handle the medicines supply chain. CONCLUSIONS: Findings showed limited awareness and readiness on supply chain management of medicines. This may be due to inadequate supply chain management skills and infrastructure, poor financing, lack of accountability and poor management. Tackling these as well as pharmacists showing more interest in the country's health policies and obtaining necessary postgraduate certifications will lead to improvements. This will improve access to quality medicines and thus help in the fight to reduce disease burden both locally and globally. PMID- 27720439 TI - Etiology of Heart Failure and Outcomes in Patients Hospitalized for Acute Decompensated Heart Failure With Preserved or Reduced Ejection Fraction. AB - In the setting of acute decompensated heart failure (HF), relations among the etiology of HF, left ventricular systolic function, and outcomes are unclear. The aim of this study was to investigate the association of HF etiology with outcomes in patients with acute decompensated HF with a preserved or reduced ejection fraction (EF). Of the 4,842 patients enrolled in the Acute Decompensated Heart Failure Syndromes registry, 3,810 patients (1,601 with a preserved EF and 2,209 with a reduced EF) who had a hypertensive, ischemic, valvular, or idiopathic dilated etiology of HF were investigated to assess the association of etiology with a composite end point (all-cause mortality and readmission for HF). The median follow-up period after admission was 502 (381 to 759) days. The composite end point was reached in 44.6% and 41.7% of the preserved and reduced EF groups, respectively. After adjustment for multiple co-morbidities, the risk of the composite end point was comparable among hypertensive, ischemic, and valvular etiologies in the preserved EF group. In contrast, in the reduced EF group, ischemic etiology was associated with a tendency toward greater risk of the composite end point than hypertensive etiology (but this difference was not significant), whereas valvular etiology was associated with a significantly greater risk of the composite end point relative to hypertensive or idiopathic dilated etiology. In conclusion, this study demonstrated that taking the etiology of HF into account may help to reduce the heterogeneity of acute decompensated HF and assist in identifying patients at risk of adverse outcomes, especially among patients with reduced EF. PMID- 27720440 TI - Allergic rhinitis and allergy are risk factors for otitis media with effusion: A meta-analysis. AB - OBJECTIVE/HYPOTHESIS: We systematically reviewed the associations between allergic rhinitis or allergy and otitis media with effusion, by reference to published data. STUDY DESIGN: A meta-analysis of case-controlled studies. DATA SOURCE: Five databases (Pubmed, Highwire, Medline, Wanfang, and China National Knowledge Infrastructure) were searched for relevant studies in the English language published prior to November 12, 2015. STUDIES CHOSEN: Studies with clearly defined experimental and control groups, in which the experimental groups had otitis media with effusion together with allergic rhinitis or allergy, were selected. METHODS: We performed a meta-analysis on data from the identified cross sectional and case-controlled studies using fixed- or random-effects models (depending on heterogeneity). We used Reviewer Manager 5.3 software to this end. RESULTS: Seven studies met the inclusion criteria. The prevalence of allergic rhinitis in patients with otitis media with effusion and the control groups differed significantly in three studies (P<0.00001), as did the prevalence of allergy (in six studies; P=0.003). CONCLUSION: Allergic rhinitis and allergy appear to be risk factors for otitis media with effusion. PMID- 27720441 TI - Aetiology, imaging features, and evolution of spontaneous perirenal haemorrhage. AB - AIM: To evaluate the aetiology, imaging features, and the evolution of spontaneous perirenal haemorrhage detected by imaging. MATERIALS AND METHODS: In this retrospective study, the hospital database was searched for all cases of spontaneous perinephric haemorrhage detected by imaging between January 2000 and December 2012. Imaging examinations were reviewed and the following parameters were recorded: the location, extension, and total volume of the haematoma, presence of active extravasation, the haematocrit effect, and highest density. The resolution time was calculated using follow-up imaging. The final aetiology for all cases was assessed via clinical, radiological, and histopathological data. Differences in imaging features of haemorrhage according to aetiology group were analysed with independent samples test and Fisher's exact test. RESULTS: Eighty-one haematomas were identified in 78 patients during this 13-year period. Causes of perirenal haemorrhage included coagulation disorders (22/81, 27.1%), ruptured renal cyst (11/81, 13.6%), rupture of abdominal aortic aneurysm (9/81, 11.1%), renal cell carcinoma (9/81, 11.1%), adrenal masses (9/81, 11.1%), polycystic kidney disease (7/81, 8.6%), angiomyolipoma (6/81, 7.4%), renal vascular diseases (2/81, 2.4%), and recurrent pyelonephritis (1/81, 1.2%). Haematomas associated with coagulation abnormalities and vascular diseases presented with larger volumes and were more likely to extent to the pararenal space more so than other groups; ruptured renal cyst and renal cell carcinomas tended to be more associated with subcapsular haematomas. The haematocrit effect and haemorrhage involving renal parenchyma were more often observed in the group with coagulation abnormalities. CONCLUSION: Imaging features, such as location and extension, could help radiologists identify possible aetiologies of spontaneous perirenal haemorrhage.

PMID- 27720443 TI - Development of a convenient and supersensitive high-throughput screening system for genetically encoded fluorescent probes of small molecules using a confocal microscope. AB - Monitoring the dynamic patterns of intracellular signaling molecules, such as inositol 1,4,5-trisphosphate (IP3) and Ca2+, that control many diverse cellular processes, provides us significant information to understand the regulatory mechanism of cellular functions. For searching more sensitive and higher dynamic range probes for signaling molecules, convenient and supersensitive high throughput screening systems are required. Here we show the optimal "in Escherichia coli (E. coli) colony" screening method based on the twin-arginine translocase (Tat) pathway and introduce a novel application of a confocal microscope as a supersensitive detection system to measure changes in the fluorescence intensity of fluorescent probes in E. coli grown on an agar plate. To verify the performance of the novel detection system, we compared the changes detected in the fluorescent intensity of genetically encoded Ca2+ indicator after Ca2+ exposure to two kinds of conventional fluorescence detection systems (luminescent image analyzer and fluorescence stereomicroscope). The rate of fluorescence change between Ca2+ binding and unbinding detected by novel supersensitive detection system was almost double than those measured by conventional detection systems. We also confirmed that the Tat pathway-based screening method is applicable to the development of genetically encoded probes for IP3. Our convenient and supersensitive screening system improves the speed of developing florescent probes for small molecules. PMID- 27720444 TI - Calcium/calmodulin-dependent serine protein kinase CASK modulates the L-type calcium current. AB - AIM: The L-type voltage-gated calcium channel Cav1.2 mediates the calcium influx into cells upon membrane depolarization. The list of cardiopathies associated to Cav1.2 dysfunctions highlights the importance of this channel in cardiac physiology. Calcium/calmodulin-dependent serine protein kinase (CASK), expressed in cardiac cells, has been identified as a regulator of Cav2.2 channels in neurons, but no experiments have been performed to investigate its role in Cav1.2 regulation. METHODS AND RESULTS: Full length or the distal C-terminal truncated of the pore-forming Cav1.2 channel (Cav1.2alpha1c), both present in cardiac cells, were expressed in TsA-201 cells. In addition, a shRNA silencer, or scramble as negative control, of CASK was co-transfected in order to silence CASK endogenously expressed. Three days post-transfection, the barium current was increased only for the truncated form without alteration of the steady state activation and inactivation biophysical properties. The calcium current, however, was increased after CASK silencing with both types of Cav1.2alpha1c subunits suggesting that, in absence of calcium, the distal C-terminal counteracts the CASK effect. Biochemistry experiments did not reveals neither an alteration of Cav1.2 channel protein expression after CASK silencing nor an interaction between Cav1.2alpha1c subunits and CASK. Nevertheless, after CASK silencing, single calcium channel recordings have shown an increase of the voltage-gated calcium channel Cav1.2 open probability explaining the increase of the whole-cell current. CONCLUSION: This study suggests CASK as a novel regulator of Cav1.2 via a modulation of the voltage-gated calcium channel Cav1.2 open probability. PMID- 27720445 TI - Outcomes with volume-based dose specification in CT-planned high-dose-rate brachytherapy for stage I-II cervical carcinoma: A 10-year institutional experience. AB - OBJECTIVE: To determine prognostic factors for progression-free survival (PFS) and overall survival (OS) for stage I-II cervical-cancer patients treated using computed-tomography (CT)-planned high-dose-rate (HDR) intracavitary brachytherapy (BT). METHODS: A total of 150 patients were treated for Stage I-II cervical cancer using CT-planned BT between 4/2004 and 10/2014. Of these, 128 were eligible for inclusion. Kaplan-Meier local control (LC), pelvic control (PC), overall survival (OS), and PFS estimates were calculated. RESULTS: After a median follow-up of 30months, the 2-year LC rate was 96%, PFS was 88%, and OS was 88%. Overall, 18 patients (14%) experienced any recurrence (AR), 8 had distant recurrence only and 10 had a combination of local, pelvic, regional, and distant recurrence. No patients had LR only. A prognostic factor for AR was tumor size >4cm (p=0.01). Patients with tumors >4cm were 3.3 times more likely to have AR than those with tumors <=4cm (hazard ratio [HR]=3.3; 95% confidence interval [CI] 1.28-9.47). Point A was 85% of prescription for tumors < 4 cm and decreased approximately 3% over 5 fractions compared to 90% of prescription for tumors > 4 cm that decreased approximately 4% over 5 fractions. Two patients (2%) experienced grade>=2 late toxicity. There were no acute or late grade>=3 toxicities. CONCLUSION: CT-planned BT resulted in excellent local control and survival. Large tumor size was associated with an increased risk of recurrence outside the radiation field and worse PFS and OS. A volume-optimized plan treated a smaller area than a point A standard plan for patients with Stage I-II cervical cancer that have received chemoradiation. Given the outstanding LC achieved with modern therapy including chemoradiation, HDR, and image-based BT, further efforts to combat spread outside the radiation field with novel therapies are warranted. PMID- 27720446 TI - Use of clinical prediction rules and D-dimer tests in the diagnostic management of pregnant patients with suspected acute pulmonary embolism. AB - Because pregnant women have an increased risk of venous thromboembolism (VTE) and at the same time normal pregnancy is associated with symptoms, mimicking those present in the setting of acute pulmonary embolism (PE), the latter diagnosis is frequently suspected in this patient category. Since imaging tests expose both mother and foetus to ionizing radiation, the ability to rule out PE based on non radiological diagnostic tests is of paramount importance. However, clinical decision rules have only been scarcely evaluated in the pregnant population with suspected PE, while D-dimer levels lose diagnostic accuracy due to a physiological increase during normal pregnancy. Consequently, clinical guidelines provide contradicting and weak recommendations on this subject and the optimal diagnostic strategy remains highly debated. With this systematic review, we aimed to summarize current evidence on the safety and efficacy of clinical decision rules and biomarkers used in the diagnostic management of suspected acute PE in pregnant patients. PMID- 27720447 TI - Changes in childhood immunization decisions in the United States: Results from 2012 & 2014 National Parental Surveys. AB - OBJECTIVE: Understanding the current status of parents' vaccine decision making is crucial to inform public policy. We sought to assess changes in vaccine decisions among parents of young children. METHODS: We conducted a web-based national poll of parents of children <7years in 2012 and 2014. Participants reported vaccine decisions for their youngest child. We calculated survey weighted population estimates of overall immunizations decisions, and delay/refusal rates for specific vaccines. RESULTS: In 2012, 89.2% (95% CI, 87.3 90.8%) reported accepting or planning to accept all recommended non-influenza childhood vaccines, 5.5% (4.5-6.6%) reported intentionally delaying one or more, and 5.4% (4.1-6.9%) reported refusing one or more vaccines. In 2014, the acceptance, delay, and refusal rates were 90.8% (89.3-92.1%), 5.6% (4.6-6.9%), and 3.6% (2.8-4.5%), respectively. Between 2012 and 2014, intentional vaccine refusal decreased slightly among parents of older children (2-6years) but not younger children (0-1years). The proportion of parents working to catch up on all vaccines increased while those refusing some but not all vaccines decreased. The South experienced a significant increase in estimated acceptance (90.1-94.1%) and a significant decrease in intentional ongoing refusal (5.0-2.1%). Vaccine delay increased in the Northeast (3.2-8.8%). CONCLUSIONS: Nationally, acceptance and ongoing intentional delay of recommended non-influenza childhood vaccines were stable. These findings suggest that more effort is warranted to counter persistent vaccine hesitancy, particularly at the local level. Longitudinal monitoring of immunization attitudes is also warranted to evaluate temporal shifts over time and geographically. PMID- 27720448 TI - Risk factors associated with hospitalisation for influenza-associated severe acute respiratory illness in South Africa: A case-population study. AB - BACKGROUND: Influenza is a common cause of severe respiratory illness, but risk factors for hospitalisation in low income settings with a high HIV prevalence are not well described. We aimed to assess risk factors associated with influenza associated severe acute respiratory illness (SARI) hospitalisation in South Africa. METHODS: We conducted a case-population study using data on risk conditions in patients hospitalised with SARI and the national prevalence of these conditions. Data on hospitalised cases were from the national SARI surveillance program while data on the referent population were from the latest national census or health and demographic surveillance surveys. FINDINGS: From 2009 to 2012, we identified 3646 (7.9%) of 46,031 enrolled cases of SARI that were associated with influenza infection. Risk factors associated with hospitalisation included previous history of smoking [case-population ratio (CPR) 3.82, 95% confidence interval (CI) 3.5-4.16], HIV infection (CPR 3.61, 95% CI 3.5 3.71), asthma (CPR 2.45, 95% CI 2.19-2.73), previous history of hospital admission in the past 12months (CPR 2.07, 95% CI 1.92-2.23), and tuberculosis (CPR 1.85, 95% CI 1.68-2.02). When stratified by age, there is increased risk of hospitalisation in those ?5yearsof age (CPR 3.07, 95% CI 2.93-3.21) and among those 35yearsof age and above (CPR 1.23, 95% CI 1.28-1.18). Male sex (CPR 0.85, 95% CI 0.82-0.88) and completion of pneumococcal conjugate vaccination schedule in children <5yearsof age (CPR 0.74, 95% CI 0.71-0.77) were associated with decreased risk of hospitalisation. CONCLUSION: These results identify groups at high-risk for severe influenza who should be considered potential targets for influenza vaccination in South Africa and similar settings. PMID- 27720449 TI - Ligand-Dependent Modulation of G Protein Conformation Alters Drug Efficacy. AB - G protein-coupled receptor (GPCR) signaling, mediated by hetero-trimeric G proteins, can be differentially controlled by agonists. At a molecular level, this is thought to occur principally via stabilization of distinct receptor conformations by individual ligands. These distinct conformations control subsequent recruitment of transducer and effector proteins. Here, we report that ligand efficacy at the calcitonin GPCR (CTR) is also correlated with ligand dependent alterations to G protein conformation. We observe ligand-dependent differences in the sensitivity of the G protein ternary complex to disruption by GTP, due to conformational differences in the receptor-bound G protein hetero trimer. This results in divergent agonist-dependent receptor-residency times for the hetero-trimeric G protein and different accumulation rates for downstream second messengers. This study demonstrates that factors influencing efficacy extend beyond receptor conformation(s) and expands understanding of the molecular basis for how G proteins control/influence efficacy. This has important implications for the mechanisms that underlie ligand-mediated biased agonism. VIDEO ABSTRACT. PMID- 27720450 TI - Competitive Disinhibition Mediates Behavioral Choice and Sequences in Drosophila. AB - Even a simple sensory stimulus can elicit distinct innate behaviors and sequences. During sensorimotor decisions, competitive interactions among neurons that promote distinct behaviors must ensure the selection and maintenance of one behavior, while suppressing others. The circuit implementation of these competitive interactions is still an open question. By combining comprehensive electron microscopy reconstruction of inhibitory interneuron networks, modeling, electrophysiology, and behavioral studies, we determined the circuit mechanisms that contribute to the Drosophila larval sensorimotor decision to startle, explore, or perform a sequence of the two in response to a mechanosensory stimulus. Together, these studies reveal that, early in sensory processing, (1) reciprocally connected feedforward inhibitory interneurons implement behavioral choice, (2) local feedback disinhibition provides positive feedback that consolidates and maintains the chosen behavior, and (3) lateral disinhibition promotes sequence transitions. The combination of these interconnected circuit motifs can implement both behavior selection and the serial organization of behaviors into a sequence. PMID- 27720452 TI - Kinetic Analysis of Protein Stability Reveals Age-Dependent Degradation. AB - Do young and old protein molecules have the same probability to be degraded? We addressed this question using metabolic pulse-chase labeling and quantitative mass spectrometry to obtain degradation profiles for thousands of proteins. We find that >10% of proteins are degraded non-exponentially. Specifically, proteins are less stable in the first few hours of their life and stabilize with age. Degradation profiles are conserved and similar in two cell types. Many non exponentially degraded (NED) proteins are subunits of complexes that are produced in super-stoichiometric amounts relative to their exponentially degraded (ED) counterparts. Within complexes, NED proteins have larger interaction interfaces and assemble earlier than ED subunits. Amplifying genes encoding NED proteins increases their initial degradation. Consistently, decay profiles can predict protein level attenuation in aneuploid cells. Together, our data show that non exponential degradation is common, conserved, and has important consequences for complex formation and regulation of protein abundance. PMID- 27720453 TI - [New patterns of substance use and abuse among French adolescents, a knowledge synthesis]. AB - AIM: There have been significant changes in adolescent consumption habits over the past fifteen years. New molecules have been synthesized, new devices created and a number of products have increased in popularity; and as a result clinicians sometimes lack information. We chose to focus on this population because of its vulnerability, as adolescents show low sensitivity to long-term outcomes of their actions and may be easily influenced by peers as regards experimentation of new drugs. The most consumed products by adolescents in France are tobacco, alcohol and cannabis with the physiological effects and consumption patterns of these drugs well documented. The purpose of this review is to identify and describe other products that are frequently used by adolescents to get high, to increase performance, for purposes of self-medication or because of peer pressure. We summarized the current scientific evidence regarding drug availability, physical and chemical properties, pharmacodynamics and adverse effects. METHOD: A literature review was conducted from 2000 to 2015 based on Pudmed, Google Scholar and governmental websites, using the following keyword alone or in combination: "adolescent", "new", "misuse", "abuse", "toxicity", "pharmacology" "cocaine", "MDMA", "inhalant", "poppers", "magic mushroom", "psilocybin", "designer drug", "legal high", "smart drug", "cathinone", "mephedrone", "cannabinoid", "prescription drug", "codeine", "opioid", "methylphenidate", "cough syrup", "purple drank". RESULTS: New products, including synthetic cannabis, cathinone or purple drank seem to be the most dangerous. They are easily accessible and may lead to short-term severe or lethal complications. Other substances do not pose a major short-term health risk by themselves. However, their consumption may be an indication of other unhealthy risk behaviors, such as prescription drug use, which may be related to psychiatric comorbidity. Unfortunately, we do not have enough data to determine the long-term consequences of the use of these substances. Moreover, these products have a strong addictive potential and may be a risk factor for other addictions. For this reason, increased supervision is justified, both for surveillance and reduction of harm. CONCLUSION: Taking care of an adolescent with substance abuse can be difficult. Updated information regarding these new substances and the particular danger they pose to adolescent health is needed. Informed clinicians can provide up to date and accurate information to the patient and family, assess potential risk factors and comorbidities, and provide appropriate support. Furthermore, because of the high prevalence of substance abuse in the adolescent population, systematic screening of adolescent consumption habit is useful to avoid or anticipate complications. Often, problematic substance consumption behaviors are signs of more complicated psychological or psychiatric issues. Substance abuse behaviors will often disappear over time but they can also become a major problem as the adolescent moves into adulthood. If problems persist, consultation with an addiction specialist may be warranted. PMID- 27720451 TI - Chemical Hybridization of Glucagon and Thyroid Hormone Optimizes Therapeutic Impact for Metabolic Disease. AB - Glucagon and thyroid hormone (T3) exhibit therapeutic potential for metabolic disease but also exhibit undesired effects. We achieved synergistic effects of these two hormones and mitigation of their adverse effects by engineering chemical conjugates enabling delivery of both activities within one precisely targeted molecule. Coordinated glucagon and T3 actions synergize to correct hyperlipidemia, steatohepatitis, atherosclerosis, glucose intolerance, and obesity in metabolically compromised mice. We demonstrate that each hormonal constituent mutually enriches cellular processes in hepatocytes and adipocytes via enhanced hepatic cholesterol metabolism and white fat browning. Synchronized signaling driven by glucagon and T3 reciprocally minimizes the inherent harmful effects of each hormone. Liver-directed T3 action offsets the diabetogenic liability of glucagon, and glucagon-mediated delivery spares the cardiovascular system from adverse T3 action. Our findings support the therapeutic utility of integrating these hormones into a single molecular entity that offers unique potential for treatment of obesity, type 2 diabetes, and cardiovascular disease. PMID- 27720455 TI - Myocardial Fibrosis in Athletes. AB - Myocardial fibrosis (MF) is a common phenomenon in the late stages of diverse cardiac diseases and is a predictive factor for sudden cardiac death. Myocardial fibrosis detected by magnetic resonance imaging has also been reported in athletes. Regular exercise improves cardiovascular health, but there may be a limit of benefit in the exercise dose-response relationship. Intense exercise training could induce pathologic cardiac remodeling, ultimately leading to MF, but the clinical implications of MF in athletes are unknown. For this comprehensive review, we performed a systematic search of the PubMed and MEDLINE databases up to June 2016. Key Medical Subject Headings terms and keywords pertaining to MF and exercise (training) were included. Articles were included if they represented primary MF data in athletes. We identified 65 athletes with MF from 19 case studies/series and 14 athletic population studies. Myocardial fibrosis in athletes was predominantly identified in the intraventricular septum and where the right ventricle joins the septum. Although the underlying mechanisms are unknown, we summarize the evidence for genetic predisposition, silent myocarditis, pulmonary artery pressure overload, and prolonged exercise induced repetitive micro-injury as contributors to the development of MF in athletes. We also discuss the clinical implications and potential treatment strategies of MF in athletes. PMID- 27720454 TI - Physical Activity and Cognitive Function in Middle-Aged and Older Adults: An Analysis of 104,909 People From 20 Countries. AB - OBJECTIVE: To examine the associations of physical activity (PA) frequency (both moderate and vigorous intensity) and PA levels with cognitive function. PATIENTS AND METHODS: Data of individuals 50 years or older, from 20 European countries (along with Israel), were collected from 2004 to November 2013 in the biannual Survey of Health, Ageing and Retirement in Europe. A total of 104,909 participants were assessed for cognitive function at least once (mean follow-up length, 29.5+/-35.7 months). Baseline moderate- and vigorous-intensity PA were reported by participants as more than once a week, once a week, one to three times a month, or hardly ever or never. With regard to PA frequency, participants were categorized as inactive, low active, intermediate active, or high active. The main outcome measure is a cognitive composite score created by summing the z scores of 4-item temporal orientation, 10-word list for delayed recall, and verbal fluency. RESULTS: Adjusted, 2-level mixed-effect regressions found that compared with doing no PA, doing PA more than once a week, once a week, or one to three times a month was positively associated with the composite score (beta coefficients varied from 0.52 to 0.75 for moderate-intensity PA and from 0.26 to 0.33 for vigorous-intensity PA). Similarly, compared with the inactive category, high-active, intermediate-active, and low-active categories had positive associations with the composite score (beta varied from 0.77 to 1.10). Positive associations were also obtained between PA variables and the raw scores of cognitive tests. CONCLUSION: Physical activity has dose-response associations with cognitive function, with even low PA frequencies (few times per month) being positively associated with cognitive function during aging. PMID- 27720456 TI - Impact of Stress Testing for Coronary Artery Disease Screening in Asymptomatic Patients With Diabetes Mellitus: A Community-Based Study in Olmsted County, Minnesota. AB - OBJECTIVE: To evaluate the impact of screening stress testing for coronary artery disease in asymptomatic patients with diabetes in a community-based population. PATIENTS AND METHODS: This observational study included 3146 patients from Olmsted County, Minnesota, with no history of coronary artery disease or cardiac symptoms in whom diabetes was newly diagnosed from January 1, 1992, through December 31, 2008. With combined all-cause mortality and myocardial infarction as the primary outcome, weighted Cox proportional hazards regression was performed with screening stress testing within 2 years of diabetes diagnosis as the time dependent covariate. For descriptive analysis, participants were classified by their clinical experience during the first 2 years postdiagnosis as screened (asymptomatic, underwent stress test), unscreened (asymptomatic, no stress test), or symptomatic (experienced symptoms or event). RESULTS: Among the screened and unscreened participants, 54% (1358 of 2538) were men; the mean (SD) age at diabetes diagnosis was 55 years (13.8 years), and 97% (2442 of 2520) had type 2 diabetes. In event-free survival analysis, 292 patients comprised the screened cohort and 2246 patients comprised the unscreened cohort. Death or myocardial infarction occurred in 454 patients (32 patients in the screened cohort and 422 in the unscreened cohort [5-year rate, 1.9% and 5.3%, respectively]) during median (interquartile range) follow-up of 9.1 years (5.3-12.5 years). Screening stress testing was associated with improved event-free survival (hazard ratio, 0.61; P=.004), independent of cardiac risk factors. However, while stress test results were abnormal in 47 of the 292 screened patients (16%), only 6 (2%) underwent coronary revascularization. CONCLUSION: Although screening cardiac stress testing in asymptomatic patients with diabetes in this community-based population was associated with improvement in long-term event-free survival, this result does not appear to occur by coronary revascularization alone. PMID- 27720457 TI - Positive Airway Pressure Therapy for Obstructive Sleep Apnea. AB - Positive airway pressure (PAP) is considered first-line therapy for moderate to severe obstructive sleep apnea and may also be considered for mild obstructive sleep apnea, particularly if it is symptomatic or there are concomitant cardiovascular disorders. Continuous PAP is most commonly used. Other modes, such as bilevel airway pressure, autotitrating positive airway pressure, average volume assured pressure support, and adaptive support ventilation, play important roles in the management of sleep-related breathing disorders. This article outlines the indications, description, and comfort features of each mode. Despite the proven efficacy of PAP in treating obstructive sleep apnea syndrome and its sequelae, adherence to therapy is low. Close follow-up of patients for evaluation of adherence to and effectiveness of treatment is important. PMID- 27720458 TI - Upper Airway Stimulation Therapy. AB - Traditional upper airway surgery directly modifies skeletal and soft tissue structures surrounding the airway to treat obstructive sleep apnea (OSA). Upper airway stimulation (UAS) attempts to treat upper airway obstruction and OSA by stimulating the hypoglossal nerve. The Inspire II implant has been approved for clinical UAS. Basic science data support that UAS prevents obstruction and improves airflow. Clinical results demonstrate that UAS improves respiratory sleep metrics and improves both objective and subjective self-reported sleep and quality-of-life outcomes. In a substantial number of individuals who meet inclusion criteria, UAS appears to be a viable, long-term, low-morbidity treatment of moderate-to-severe OSA. PMID- 27720459 TI - Skeletal Surgery for Obstructive Sleep Apnea. AB - Multilevel surgery has been established as the mainstay of treatment for the surgical management of obstructive sleep apnea (OSA). Combined with uvulopalatopharyngoplasty, tongue-base surgeries, including the genioglossus advancement (GA), sliding genioplasty, and hyoid myotomy and suspension, have been developed to target hypopharyngeal obstruction. Total airway surgery consisting of maxillomandibular advancement (MMA) with/without GA has shown significant success. Skeletal procedures for OSA with or without a palatal procedure is a proven technique for relieving airway obstruction during sleep. A case study demonstrating the utility of virtual surgical planning for MMA surgery is presented. PMID- 27720460 TI - Palatal Procedures for Obstructive Sleep Apnea. AB - Uvulopalatopharyngoplasty was the first surgical procedure described, other than tracheostomy, for the treatment of obstructive sleep apnea (OSA) in 1981. It was recognized then that there were responders who were cured of OSA with the procedure and others that were not. It took many years for a staging system to be described that categorized patients based on Mallampati score, tonsil size, and body mass index to better predict success rates. It was recognized that individuals with retro-palatal obstruction as the cause of the airway obstruction responded well but that the morbidity associated with the inpatient procedure was often problematic. PMID- 27720461 TI - Oral Appliances in Obstructive Sleep Apnea. AB - Oral appliance therapy (OAT) has become an increasingly popular nonsurgical option for the treatment of obstructive sleep disorders. Recent research supports its efficacy and high levels of compliance for patients with obstructive sleep disorders. Common side effects of OAT include temporomandibular joint-related symptoms, bite changes, and tooth movement. These side effects can be minimized by the use of exercises. The American Academy of Dental Sleep Medicine and the American Academy of Sleep Medicine have released joint clinical practice guidelines for the treatment of obstructive sleep apnea and snoring with OAT. PMID- 27720462 TI - An Introduction to Obstructive Sleep Apnea. AB - Obstructive sleep apnea (OSA) is a prevalent disease entity that has become commonplace over the past few decades. Its surge in diagnosis can be linked to a better understanding of the process with a concurrent increase in prevalence. The social, economic, and personal impacts are significant; there continues to be a need to improve our treatment modalities for OSA. PMID- 27720463 TI - Nasal Surgery for Obstructive Sleep Apnea Syndrome. AB - Obstructive sleep apnea is a common condition, primarily caused by narrowing of the nasal and pharyngeal airway. Treatment with continuous positive airway pressure (CPAP) is considered the first line of therapy, but long-term compliance is only about 40%, often because of nasal obstruction. Any nasal obstruction can worsen CPAP compliance. Treatment of the nasal obstruction with topical nasal steroid sprays or nasal dilators has been shown to improve sleep disordered breathing. Surgical treatment of nasal obstruction, has been shown to improve sleep disordered breathing, as well as CPAP requirement and compliance with CPAP. PMID- 27720464 TI - The skin aging exposome. AB - The term "exposome" describes the totality of exposures to which an individual is subjected from conception to death. It includes both external and internal factors as well as the human body's response to these factors. Current exposome research aims to understand the effects all factors have on specific organs, yet today, the exposome of human skin has not received major attention and a corresponding definition is lacking. This review was compiled with the collaboration of European scientists, specialized in either environmental medicine or skin biology. A comprehensive review of the existing literature was performed using PubMed. The search was restricted to exposome factors and skin aging. Key review papers and all relevant, epidemiological, in vitro, ex vivo and clinical studies were analyzed to determine the key elements of the exposome influencing skin aging. Here we propose a definition of the skin aging exposome. It is based on a summary of the existing scientific evidence for the role of exposome factors in skin aging. We also identify future research needs which concern knowledge about the interaction of distinct exposomal factors with each other and the resulting net effects on skin aging and suggest some protective measures.

AB - BACKGROUND: Dioxins and other environmental pollutants are toxic and remain in biological tissues for a long time leading to various levels of oxidative stress. Although the toxicity of these agents has been linked to activation of the aryl hydrocarbon receptor (AHR), no effective treatment has been developed. OBJECTIVE: To explore novel phytochemicals that inhibit AHR activation in keratinocytes. METHODS: Keratinocytes were used in this study because the skin is one of the organs most affected by dioxin and other environmental pollutants. HaCaT cells, which are a human keratinocyte cell line, and normal human epidermal keratinocytes were stimulated with benzo[a]pyrene to induce AHR activation, and the effects of traditional Japanese Kampo herbal formulae were analyzed. Quantification of mRNA, western blotting, immunofluorescence localization of molecules, siRNA silencing, and visualization of oxidative stress were performed. RESULTS: Cinnamomum cassia extract and its major constituent cinnamaldehyde significantly inhibited the activation of AHR. Cinnamaldehyde also activated the NRF2/HO1 pathway and significantly alleviated the production of reactive oxygen species in keratinocytes. The inhibition of AHR signaling and the activation of antioxidant activity by cinnamaldehyde operated in a mutually independent manner as assessed by siRNA methods In addition, AHR signaling was effectively inhibited by traditional Kampo formulae containing C. cassia. CONCLUSION: Cinnamaldehyde has two independent biological activities; namely, an inhibitory action on AHR activation and an antioxidant effect mediated by NRF2/HO1 signaling. Through these dual functions, cinnamaldehyde may be beneficial for the treatment of disorders related to oxidative stress such as dioxin intoxication, acne, and vitiligo.

AB - Pipelines are one of the most popular and effective ways of transporting hazardous materials, especially natural gas. However, the rapid development of gas pipelines and stations in urban areas has introduced a serious threat to public safety and assets. Although different methods have been developed for risk analysis of gas transportation systems, a comprehensive methodology for risk analysis is still lacking, especially in natural gas stations. The present work is aimed at developing a dynamic and comprehensive quantitative risk analysis (DCQRA) approach for accident scenario and risk modeling of natural gas stations. In this approach, a FMEA is used for hazard analysis while a Bow-tie diagram and Bayesian network are employed to model the worst-case accident scenario and to assess the risks. The results have indicated that the failure of the regulator system was the worst-case accident scenario with the human error as the most contributing factor. Thus, in risk management plan of natural gas stations, priority should be given to the most probable root events and main contribution factors, which have identified in the present study, in order to reduce the occurrence probability of the accident scenarios and thus alleviate the risks. PMID- 27720468 TI - Superb adsorption capacity of hierarchical calcined Ni/Mg/Al layered double hydroxides for Congo red and Cr(VI) ions. AB - The preparation of hierarchical porous materials as catalysts and sorbents has attracted much attention in the field of environmental pollution control. Herein, Ni/Mg/Al layered double hydroxides (NMA-LDHs) hierarchical flower-like hollow microspheres were synthesized by a hydrothermal method. After the NMA-LDHs was calcined at 600 degrees C, NMA-LDHs transformed into Ni/Mg/Al layered double oxides (NMA-LDOs), which maintained the hierarchical flower-like hollow structure. The crystal phase, morphology, and microstructure of the as-prepared samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy elemental mapping, Fourier transform infrared spectroscopy, and nitrogen adsorption desorption methods. Both the calcined and non-calcined NMA-LDHs were examined for their performance to remove Congo red (CR) and hexavalent chromium (Cr(VI)) ions in aqueous solution. The maximum monolayer adsorption capacities of CR and Cr(VI) ions over the NMA-LDOs sample were 1250 and 103.4mg/g at 30 degrees C, respectively. Thermodynamic studies indicated that the adsorption process was endothermic in nature. In addition, the addition of coexisting anions negatively influenced the adsorption capacity of Cr(VI) ions, in the following order: CO32 >SO42->H2PO4->Cl-. This work will provide new insight into the design and fabrication of advanced adsorption materials for water pollutant removal. PMID- 27720469 TI - Complete removal of arsenic and zinc from a heavily contaminated acid mine drainage via an indigenous SRB consortium. AB - Acid mine drainages (AMD) are major sources of pollution to the environment. Passive bio-remediation technologies involving sulfate-reducing bacteria (SRB) are promising for treating arsenic contaminated waters. However, mechanisms of biogenic As-sulfide formation need to be better understood to decontaminate AMDs in acidic conditions. Here, we show that a high-As AMD effluent can be decontaminated by an indigenous SRB consortium. AMD water from the Carnoules mine (Gard, France) was incubated with the consortium under anoxic conditions and As, Zn and Fe concentrations, pH and microbial activity were monitored during 94days. Precipitated solids were analyzed using electron microscopy (SEM/TEM-EDXS), and Extended X-Ray Absorption Fine Structure (EXAFS) spectroscopy at the As K-edge. Total removal of arsenic and zinc from solution (1.06 and 0.23mmol/L, respectively) was observed in two of the triplicates. While Zn precipitated as ZnS nanoparticles, As precipitated as amorphous orpiment (am-AsIII2S3) (33-73%), and realgar (AsIIS) (0-34%), the latter phase exhibiting a particular nanowire morphology. A minor fraction of As is also found as thiol-bound AsIII (14-23%). We propose that the formation of the AsIIS nanowires results from AsIII2S3 reduction by biogenic H2S, enhancing the efficiency of As removal. The present description of As immobilization may help to set the basis for bioremediation strategies using SRB. PMID- 27720470 TI - Metagenomic insight into the bioaugmentation mechanism of Phanerochaete chrysosporium in an activated sludge system treating coking wastewater. AB - Phanerochaete chrysosporium was seeded to a sequencing batch reactor treating phenol wastewater. Compared to the contrast reactor (R1), the bioaugmented reactor (R2) exhibits better performance in sludge settling ability, as well as biomass and phenol removal, even though the added fungus is not persistently surviving in the reactor. Bioaugmentation improved bacterial population, growing up to 10,000 times higher than that of eukaryotes. Metagenomic sequencing results show the bioaugmentation finally increases bacterial and eukaryotic richness, but reduces their community diversity. In contrast to R1, bacterial distribution in R2 is more concentrated in Proteobacteria. The relative abundances of filamentous fungi, yeast and microalgae in R2 are all higher than those in R1 at different treatment phases, and two reactors are finally dominated by different protozoan and metazoan. In conclusion, P. chrysosporium improves reactor performances by influencing microbial community structure, and this phenomenon might be attributed to the ecological competition in sludge and toxicity reduction of phenol wastewater. The novelty of this study emphasizes why a species which is not persistently active in bioreactor still plays a crucial role in enhancing reactor performance. Results obtained here impact the conventional criteria for selection of bioaugmentation microbes used in activated sludge systems. PMID- 27720471 TI - Physiological and behavioural impacts of Pacific ciguatoxin-1 (P-CTX-1) on marine medaka (Oryzias melastigma). AB - Ciguatoxins (CTXs) are natural biotoxins produced by benthic dinoflagellates of the genus Gambierdiscus, which are bioaccumulated and biotransformed along food chains in coral ecosystems. They are neurotoxins that activate voltage-gated sodium channels and disrupt ion conductance in the excitable tissues. Pacific ciguatoxin-1 (P-CTX-1) is the most prevalent and potent CTX congener present in fishes from the Pacific Ocean. In this study, P-CTX-1 was administrated to larval marine medaka (2h post-hatch) via microinjection. Exposure to P-CTX-1 at sub-ppb levels led to adverse behavioural changes, altered physiological performances and reduced survivability of the larval marine medaka as early as 24h after exposure. P-CTX-1 decreased the rate of heartbeat and locomotion of the exposed larvae, probably owing to a series of physiological processes and morphological changes such as pericardial oedema, failure of swim bladder inflation and spinal curvature. The exposed larval marine medaka also demonstrated reduced, delayed and paralyzed responses to external stimulations. This may render them more susceptible to predation. P-CTX-1 could be effectively distributed from the yolk sac to all parts of the fish body, including head and trunk, 24h after exposure. Repeated low-dose P-CTX-1 exposure resulted in larval mortality comparable to that of a single high-dose exposure. PMID- 27720472 TI - Viability of a nanoremediation process in single or multi-metal(loid) contaminated soils. AB - The effectiveness of single- and multi-metal(loid) immobilization of As, Cd, Cr, Pb and Zn using different doses of nanoscale zero-valent iron (nZVI) was evaluated and compared in two different soils, a calcareous and an acidic one. The effectiveness of nZVI to immobilize metal(loid)s in soil strongly depended on the metal characteristics, soil properties, dose of nZVI and presence of other metal(loid)s. In the case of single contamination, this nanoremediation strategy was effective for all of the metal(loid)s studied except for Cd. When comparing the two soils, anionic metal(loid)s (As and Cr) were more easily retained in acidic soil, whereas cationic metal(loid)s (Cd, Pb and Zn), were immobilized more in calcareous soil. In multi-metal(loid) contaminated soils, the presence of several metal(loid)s affected their immobilization, which was probably due to the competitive phenomenon between metal(loid) ions, which can reduce their sorption or produce synergistic effects. At 10% of nZVI, As, Cr and Pb availability decreased more than 82%, for Zn it ranged between 31 and 75% and for Cd between 13 and 42%. Thus, the application of nZVI can be a useful strategy to immobilize As, Cr, Pb and Zn in calcareous or acidic soils in both single- or multi metal(loid) contamination conditions. PMID- 27720473 TI - Microaerobic degradation of 2-Mercaptobenzothiazole present in industrial wastewater. AB - Microaerobic degradation of 2-Mercaptobenzothiazole (2-MBT) was investigated using an isolated bacterial strain CSMB1. It was identified as Alcaligenes sp. MH146 by genomic analysis. The isolate degraded 50mg/L concentration of 2-MBT which was measured in terms of Total organic carbon (TOC) (700mg/L). A maximum degradation of 86% with a residual TOC concentration of 101mg/L was obtained after 72h, with the biomass growth of 290mg/L. The presence of specific activity of catechol 2, 3 oxygenase was observed in all the tested derivatives of benzothiazoles and the benzene ring opening was observed through meta cleavage. By analyzing the 72h incubated culture supernatant, 2-MBT, and all its biotransformed products were degraded into polar compounds. With the analytical results obtained, a possible microaerobic degradative pathway was proposed and illustrated for 2-MBT. It is concluded that microaerophilic isolate CSMB1 was able to degrade 2-MBT and its intermediates by utilizing them as sole carbon and energy. PMID- 27720474 TI - Modeling and Elucidation of the Kinetics of Multiple Consecutive Photoreactions AB4(4Phi) With Phi-order Kinetics. Application to the Photodegradation of Riboflavin. AB - New semi-empirical rate-law system of equations is proposed for the first time for consecutive photoreactions that involve up to 4 photoreaction steps, AB4(4Phi). The equation system was developed, tested, and validated against synthetic kinetic traces generated by fifth-order Runge-Kutta calculations. The model accurately fitted the kinetic traces of Riboflavin photodegradation in ethanol which decomposes via the AB2(2Phi) mechanism involving 2 consecutive photoreaction steps. A kinetic elucidation methodology useful for consecutive photoreactions was also proposed to determine all the kinetic parameters and reaction attributes defining AB2(2Phi) reactions. The quantum yields of photodegradation, determined for wavelengths in the visible region 400-480 nm, ranged from 0.005 to 0.00756 and 0.0012 to 8 10-5 for the first and second photoreaction steps, respectively. They were found to increase with wavelength in defined sigmoid functions. For this monochromatic irradiation range, riboflavin proved to be a useful actinometer. Finally, a photodegradation scale based on pseudo-rate-constant values was also proposed for drugs. This scale (including 4 groups) is thought to contribute to rationalizing photodegradation testing and might prove useful in categorizing drugs' photodegradation reactivity.

PMID- 27720476 TI - Nanominerals and potentially hazardous elements from coal cleaning rejects of abandoned mines: Environmental impact and risk assessment. AB - Soils around coal mining are important reservoir of hazardous elements (HEs), nanominerals, and ultrafine compounds. This research reports and discusses the soil concentrations of HEs (As, Cd, Cr, Cu, Ni, Pb, and Zn) in coal residues of abandoned mines. To assess differences regarding environmental impact and risk assessment between coal abandoned mines from the Santa Catarina state, eighteen coal cleaning rejects with different mineralogical and chemical composition, from eight abandoned mines were collected. Nanominerals and ultra-fine minerals from mining-contaminated areas were analyzed by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and high-resolution transmission electron microscope (HR-TEM), providing new information on the mineralogy and nano-mineralogy of these coal residues. The total contents of 57 elements (HEs, alkali metals, and rare earth elements) were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The calculation of NWACs (Normalized Average Weighted Concentration), together with the chemometric analysis by Principal component analysis (PCA) confirmed the variability of the samples regarding their city and their mine of origin. Moreover, the results confirmed the existence of hotspots in mines near urban areas. PMID- 27720477 TI - Hybrid controller with observer for the estimation and rejection of disturbances. AB - In this paper, a hybrid controller with observer is introduced for the estimation and rejection of a disturbance. It is based on the combination of the sliding mode technique and the output feedback strategy. It is divided into two designs: (1) the observer and (2) the controller with observer. The observer is selected to reach two objectives: (a) to assure its stability and (b) for the estimation of a disturbance. The controller with observer is selected to reach three objectives: (a) to assure its stability, (b) for the rejection of a disturbance, and (c) for the decreasing of chattering in the sliding mode behavior. The proposed method is applied for the estimation and rejection of the disturbance in a plotter and a suspension system.

PMID- 27720479 TI - Two cases of thermal burns of the larynx in older men. AB - Cases of thermal burns of the larynx in infants and in patients with mental illness have been reported, but those in older people are rare. We report two cases of thermal burns of the larynx in older people caused by ingestion of microwave-heated food (meat and potato stew or a bean-jam filled bun). Both patients were users of full dentures. Conservative therapy was effective in one patient, while tracheotomy was performed in the other patient at the time of the initial examination. Hot food is expelled from the mouth as a reflective response, preventing thermal burns of the larynx. However, in older individuals, sense perception is impaired and reflexes are slowed. Further, the oral mucosa is protected if full dentures are placed. Therefore, heat is likely to not be perceived and reflexes occur only after the food has reached the larynx, thereby causing thermal burns of the larynx. The number of such cases may increase as the number of older patients rises in the current aging society. Therefore, raising awareness of such cases is important. PMID- 27720480 TI - Basaloid squamous cell carcinoma arising in an inverted papilloma in the nasal cavity: A case report and review. AB - Basaloid squamous cell carcinoma (BSCC) is a histologically distinctive variant of squamous cell carcinoma comprising basal cell carcinoma and squamous cell carcinoma. BSCC is aggressive and shows a poor prognosis because of frequent lymph node invasion and distant metastases. BSCC preferentially occurs in the cervix, thymus, and esophagus and is uncommonly found in the head and neck region. BSCC in the nasal cavity or paranasal sinus is particularly rare. Inverted papilloma is an uncommon, benign tumor with a propensity to be associated with malignancy; however, BSCC arising in an inverted papilloma has never been reported. Here we report a case of a 56-year-old woman with BSCC arising in an inverted papilloma in the nasal cavity. The woman was referred to our hospital for epistaxis, nasal congestion, and dysphagia. A tumor was observed to completely occupy the left nasal cavity. The biopsy specimen was histologically diagnosed as papilloma. Computed tomography demonstrated a tumor with heterogeneous contrast effect occupying the left nasal cavity; however, extra-nasal tract extension was not observed. We performed endoscopic excision of the tumor. Microscopic findings confirmed the diagnosis of BSCC arising from an inverted papilloma. No tumor recurrence has been observed for 13 months after surgery. PMID- 27720482 TI - Laminar Module Cascade from Layer 5 to 6 Implementing Cue-to-Target Conversion for Object Memory Retrieval in the Primate Temporal Cortex. AB - The cerebral cortex computes through the canonical microcircuit that connects six stacked layers; however, how cortical processing streams operate in vivo, particularly in the higher association cortex, remains elusive. By developing a novel MRI-assisted procedure that reliably localizes recorded single neurons at resolution of six individual layers in monkey temporal cortex, we show that transformation of representations from a cued object to a to-be-recalled object occurs at the infragranular layer in a visual cued-recall task. This cue-to target conversion started in layer 5 and was followed by layer 6. Finally, a subset of layer 6 neurons exclusively encoding the sought target became phase locked to surrounding field potentials at theta frequency, suggesting that this coordinated cell assembly implements cortical long-distance outputs of the recalled target. Thus, this study proposes a link from local computation spanning laminar modules of the temporal cortex to the brain-wide network for memory retrieval in primates. PMID- 27720481 TI - Poly(GR) in C9ORF72-Related ALS/FTD Compromises Mitochondrial Function and Increases Oxidative Stress and DNA Damage in iPSC-Derived Motor Neurons. AB - GGGGCC repeat expansions in C9ORF72 are the most common genetic cause of both ALS and FTD. To uncover underlying pathogenic mechanisms, we found that DNA damage was greater, in an age-dependent manner, in motor neurons differentiated from iPSCs of multiple C9ORF72 patients than control neurons. Ectopic expression of the dipeptide repeat (DPR) protein (GR)80 in iPSC-derived control neurons increased DNA damage, suggesting poly(GR) contributes to DNA damage in aged C9ORF72 neurons. Oxidative stress was also increased in C9ORF72 neurons in an age dependent manner. Pharmacological or genetic reduction of oxidative stress partially rescued DNA damage in C9ORF72 neurons and control neurons expressing (GR)80 or (GR)80-induced cellular toxicity in flies. Moreover, interactome analysis revealed that (GR)80 preferentially bound to mitochondrial ribosomal proteins and caused mitochondrial dysfunction. Thus, poly(GR) in C9ORF72 neurons compromises mitochondrial function and causes DNA damage in part by increasing oxidative stress, revealing another pathogenic mechanism in C9ORF72-related ALS and FTD. PMID- 27720483 TI - The Calcium Channel Subunit Alpha2delta2 Suppresses Axon Regeneration in the Adult CNS. AB - Injuries to the adult CNS often result in permanent disabilities because neurons lose the ability to regenerate their axon during development. Here, whole transcriptome sequencing and bioinformatics analysis followed by gain- and loss of-function experiments identified Cacna2d2, the gene encoding the Alpha2delta2 subunit of voltage-gated calcium channels (VGCCs), as a developmental switch that limits axon growth and regeneration. Cacna2d2 gene deletion or silencing promoted axon growth in vitro. In vivo, Alpha2delta2 pharmacological blockade through Pregabalin (PGB) administration enhanced axon regeneration in adult mice after spinal cord injury (SCI). As PGB is already an established treatment for a wide range of neurological disorders, our findings suggest that targeting Alpha2delta2 may be a novel treatment strategy to promote structural plasticity and regeneration following CNS trauma. PMID- 27720484 TI - A LRRK2-Dependent EndophilinA Phosphoswitch Is Critical for Macroautophagy at Presynaptic Terminals. AB - Synapses are often far from the soma and independently cope with proteopathic stress induced by intense neuronal activity. However, how presynaptic compartments turn over proteins is poorly understood. We show that the synapse enriched protein EndophilinA, thus far studied for its role in endocytosis, induces macroautophagy at presynaptic terminals. We find that EndophilinA executes this unexpected function at least partly independent of its role in synaptic vesicle endocytosis. EndophilinA-induced macroautophagy is activated when the kinase LRRK2 phosphorylates the EndophilinA-BAR domain and is blocked in animals where EndophilinA cannot be phosphorylated. EndophilinA-phosphorylation promotes the formation of highly curved membranes, and reconstitution experiments show these curved membranes serve as docking stations for autophagic factors, including Atg3. Functionally, deregulation of the EndophilinA phosphorylation state accelerates activity-induced neurodegeneration. Given that EndophilinA is connected to at least three Parkinson's disease genes (LRRK2, Parkin and Synaptojanin), dysfunction of EndophilinA-dependent synaptic macroautophagy may be common in this disorder. PMID- 27720485 TI - Reduction of Nuak1 Decreases Tau and Reverses Phenotypes in a Tauopathy Mouse Model. AB - Many neurodegenerative proteinopathies share a common pathogenic mechanism: the abnormal accumulation of disease-related proteins. As growing evidence indicates that reducing the steady-state levels of disease-causing proteins mitigates neurodegeneration in animal models, we developed a strategy to screen for genes that decrease the levels of tau, whose accumulation contributes to the pathology of both Alzheimer disease (AD) and progressive supranuclear palsy (PSP). Integrating parallel cell-based and Drosophila genetic screens, we discovered that tau levels are regulated by Nuak1, an AMPK-related kinase. Nuak1 stabilizes tau by phosphorylation specifically at Ser356. Inhibition of Nuak1 in fruit flies suppressed neurodegeneration in tau-expressing Drosophila, and Nuak1 haploinsufficiency rescued the phenotypes of a tauopathy mouse model. These results demonstrate that decreasing total tau levels is a valid strategy for mitigating tau-related neurodegeneration and reveal Nuak1 to be a novel therapeutic entry point for tauopathies. PMID- 27720486 TI - A Designer AAV Variant Permits Efficient Retrograde Access to Projection Neurons. AB - Efficient retrograde access to projection neurons for the delivery of sensors and effectors constitutes an important and enabling capability for neural circuit dissection. Such an approach would also be useful for gene therapy, including the treatment of neurodegenerative disorders characterized by pathological spread through functionally connected and highly distributed networks. Viral vectors, in particular, are powerful gene delivery vehicles for the nervous system, but all available tools suffer from inefficient retrograde transport or limited clinical potential. To address this need, we applied in vivo directed evolution to engineer potent retrograde functionality into the capsid of adeno-associated virus (AAV), a vector that has shown promise in neuroscience research and the clinic. A newly evolved variant, rAAV2-retro, permits robust retrograde access to projection neurons with efficiency comparable to classical synthetic retrograde tracers and enables sufficient sensor/effector expression for functional circuit interrogation and in vivo genome editing in targeted neuronal populations. VIDEO ABSTRACT. PMID- 27720487 TI - Stress Increases Ethanol Self-Administration via a Shift toward Excitatory GABA Signaling in the Ventral Tegmental Area. AB - Stress is a well-known risk factor for subsequent alcohol abuse, but the neural mechanisms underlying interactions between stress and alcohol remain largely unknown. Addictive drug reinforcement and stress signaling involve common neural circuitry, including the mesolimbic dopamine system. We demonstrate in rodents that pre-exposure to stress attenuates alcohol-induced dopamine responses and increases alcohol self-administration. The blunted dopamine signaling resulted from ethanol-induced excitation of GABA neurons in the ventral tegmental area. Excitation of GABA neurons was mediated by GABAA receptor activation and involved stress-induced functional downregulation of the K+, Cl- cotransporter, KCC2. Blocking stress hormone receptors, enhancing KCC2 function, or preventing excitatory GABA signaling by alternative methods all prevented the attenuated alcohol-induced dopamine response and prevented the increased alcohol self administration. These results demonstrate that stress alters the neural and behavioral responses to alcohol through a neuroendocrine signal that shifts inhibitory GABA transmission toward excitation.

PMID- 27720488 TI - Amygdala and Ventral Striatum Make Distinct Contributions to Reinforcement Learning. AB - Reinforcement learning (RL) theories posit that dopaminergic signals are integrated within the striatum to associate choices with outcomes. Often overlooked is that the amygdala also receives dopaminergic input and is involved in Pavlovian processes that influence choice behavior. To determine the relative contributions of the ventral striatum (VS) and amygdala to appetitive RL, we tested rhesus macaques with VS or amygdala lesions on deterministic and stochastic versions of a two-arm bandit reversal learning task. When learning was characterized with an RL model relative to controls, amygdala lesions caused general decreases in learning from positive feedback and choice consistency. By comparison, VS lesions only affected learning in the stochastic task. Moreover, the VS lesions hastened the monkeys' choice reaction times, which emphasized a speed-accuracy trade-off that accounted for errors in deterministic learning. These results update standard accounts of RL by emphasizing distinct contributions of the amygdala and VS to RL. PMID- 27720490 TI - A Retrospective Analysis of the Influence of Ventricular Morphology on the Perioperative Outcomes After Fontan Surgery. AB - OBJECTIVES: The objectives of this study were to evaluate the effect of ventricular morphology on perioperative outcomes during Fontan surgery. DESIGN: Retrospective cohort study. SETTING: Single standing, not-for-profit pediatric hospital. PARTICIPANTS: A total of 72 patients who underwent Fontan surgery using cardiopulmonary bypass without aortic cross-clamp between January 1, 2009 and December 31, 2014. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The patients were divided into 3 categories depending on their single-ventricle lesions: (1) LV group (n = 20): left dominant and hypoplastic right ventricle; (2) RV group (n = 37): right dominant and hypoplastic left ventricle; and (3) BV group (n = 15): biventricular or indeterminate dominance. Perioperative major adverse events were collected based on the Society of Thoracic Surgeons database. The need for perioperative allogeneic blood transfusions also was determined. The mean age was 3.3+/-1.7 years and the mean weight was 13.6+/-4.0 kg. All patients had extracardiac lateral tunnel or conduit Fontan procedures. Sixty-nine of the patients (96%) underwent tracheal extubation in the operating room. Anesthesia, surgery, and CPB times were 326+/-68, 239+/-73, and 70+/-41 minutes, respectively. Eleven patients (15%) required allogeneic blood products intraoperatively, while 30 patients (42%) required allogeneic blood products during the perioperative period. Length of cardiac intensive care unit stay and hospital stay (median [IQR]) were 1 [1,2] and 12 [9,18] days, respectively. There was no mortality and no significant differences between groups in major postoperative complications, anesthetic or surgical variables. CONCLUSIONS: No difference in the immediate perioperative outcomes was noted based on ventricular morphology.

AB - OBJECTIVE: To identify risks factors associated with acute kidney injury (AKI) after esophageal cancer surgery. DESIGN: This was a retrospective study. SETTING: Single academic center. PARTICIPANTS: Subjects with non-metastatic esophageal cancer. Patients were excluded if they were younger than 18 years and had missing data. MEASUREMENTS AND MAIN RESULTS: Primary outcome of the study was AKI according to AKI Network criteria. Demographic and perioperative variables were compared in patients with and without AKI. A multivariate Cox proportional model was used to assess the association between perioperative variables and AKI; p<0.05 was considered statistically significant. AKI was found in 107 (11.9%) of the 898 patients included in the study. The multivariate analysis also showed that BMI (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.03-1.11), number of comorbidities (OR 1.52, 95% CI 1.20-1.93, p = 0.001), and preoperative creatinine concentrations (OR 2.37, 95% CI 1.14-4.92, p = 0.02) were independent predictors for AKI. The use of dexamethasone was associated with a reduced risk for AKI. CONCLUSIONS: In support of previous reports in the literature, the authors found that AKI was not an uncommon complication after esophageal surgery. Obesity, cardiovascular comorbidities, and high preoperative concentrations were predictors of AKI. Dexamethasone administration during surgery appeared to have a protective effect. This finding opens an opportunity to further study in a randomized controlled trial the efficacy of dexamethasone in the prevention of AKI.

PMID- 27720493 TI - Epidural Hematoma and Abscess Related to Thoracic Epidural Analgesia: A Single Center Study of 2,907 Patients Who Underwent Lung Surgery. AB - OBJECTIVE: To report the major complications (epidural hematoma and abscess) of postoperative thoracic epidural analgesia in patients who underwent lung surgery. DESIGN: Prospective, monocentric study. SETTING: A university hospital. PARTICIPANTS: All lung surgical patients who received postoperative thoracic epidural analgesia between November 2007 and November 2015. INTERVENTIONS: Thoracic epidural analgesia for patients who underwent lung surgery. MEASUREMENTS AND MAIN RESULTS: During the study period, data for 2,907 patients were recorded. The following 3 major complications were encountered: 1 case of epidural hematoma (0.34 case/1,000; 95% confidence interval 0.061-1.946), for which surgery was performed, and 2 cases of epidural abscesses (0.68 case/1,000; 95% confidence interval 0.189-2.505), which were treated medically. CONCLUSIONS: The risk range of serious complications was moderate; only the patient who experienced an epidural hematoma also experienced permanent sequelae. PMID- 27720494 TI - Assessment of Changes in Hemodynamics and Intrathoracic Fluid Using Electrical Cardiometry During Autologous Blood Harvest. AB - OBJECTIVE: To evaluate the effect of autologous blood harvest (ABH)-induced volume shifts using electrical cardiometry (EC) in patients with pulmonary artery hypertension secondary to left heart disease. DESIGN: Prospective, randomized, controlled trial. SETTING: A tertiary care hospital. PARTICIPANTS: The study comprised 50 patients scheduled to undergo heart valve replacement. INTERVENTIONS: Patients were divided randomly into 2 experimental groups that were distinguished by whether ABH was performed. Blood volume extracted in the test group was replaced simultaneously with 1:1 colloid (Tetraspan; B Braun Melsungen, Melsungen, Germany). Hemodynamic, respiratory, and EC-derived parameters were recorded at predefined set points (T1 [post-induction/pre-ABH] and T2 [20 minutes post-ABH]). MEASUREMENTS AND MAIN RESULTS: Withdrawal of 15% of blood volume in the ABH group caused significant reductions in thoracic fluid content (TFC) (-10.1% [-15.0% to -6.1%]); right atrial pressure (-23% [-26.6% to 17.6%]); mean arterial pressure (-12.6% [-22.2% to -3.8%]); airway pressures: (peak -6.2% [-11.7% to -2.8%] and mean -15.4% [-25.0% to -8.3%]); and oxygenation index (-10.34% [-16.4% to -4.8%]). Linear regression analysis showed good correlation between the percentage change in TFC after ABH and the percentage of change in right atrial pressure, stroke volume variation, autologous blood extracted, peak and mean airway pressures, and oxygen index. CONCLUSIONS: In addition to its proven role in blood conservation, therapeutic benefits derived from ABH include decongestion of volume-loaded patients, decrease in TFC, and improved gas exchange. EC tracks beat-to-beat fluid and hemodynamic fluctuations during ABH and helps in the execution of an early patient-specific, goal-directed therapy, allowing for its safe implementation in patients with pulmonary hypertension secondary to left heart disease. PMID- 27720495 TI - A New Modified Evans Blue Dye Test as Screening Test for Aspiration in Tracheostomized Patients. AB - OBJECTIVE: The authors assessed the diagnostic accuracy of a new modified Evans blue dye test (MEBDT) as a screening test for aspiration in tracheostomized patients. DESIGN: Monocentric retrospective study performed between October 2013 and December 2015. SETTING: Anesthesia and Intensive Care Unit, Second University of Naples. PARTICIPANTS: Among 62 eligible patients, 5 were excluded. The authors' study population included 57 patients. INTERVENTIONS: Patients underwent both fiberoptic endoscopic examination of the swallow (FEES) and MEBDT to evaluate swallow. The MEBDT results were compared with those of FEES and the diagnostic accuracy of MEBDT was calculated using the FEES as the gold standard. MEASUREMENTS AND MAIN RESULTS: The authors found that both FEES and MEBDT were positive for aspiration in 40 patients (true-positive MEBDT); FEES and MEBDT were negative in 10 (true-negative MEBDT). On the other hand, FEES was positive with an MEBDT negative in 7 patients (false-negative MEBDT), and there were no FEES negative and MEBDT positive (false-positive MEBDT). MEBDT had a sensitivity, specificity, positive, and negative predicted value of 85%, 100%, 100%, and 58.82%, respectively. CONCLUSIONS: MEBDT could be a supplementary diagnostic test for aspiration. Patients with positive MEBDT should not undergo oral feeding, while patients with negative MEBDT should undergo FEES before starting oral feeding.

PMID- 27720497 TI - Low-molecular-weight heparin and recurrent placenta-mediated pregnancy complications: a meta-analysis of individual patient data from randomised controlled trials. AB - BACKGROUND: Placenta-mediated pregnancy complications include pre-eclampsia, late pregnancy loss, placental abruption, and birth of a small-for-gestational-age (SGA) neonate. These complications are leading causes of maternal, fetal, and neonatal morbidity and mortality in high-income countries. Affected women are at high risk of recurrence in subsequent pregnancies; however, effective strategies to prevent recurrence are absent. Findings from our previous study-level meta analysis suggested that low-molecular-weight heparin reduced the risk of recurrent placenta-mediated pregnancy complications. However, we identified significant heterogeneity in the results, possibly due to trial design or inclusion criteria. To identify which patients benefit from, and which outcomes are prevented by, low-molecular-weight heparin, we did an individual patient data meta-analysis. METHODS: We did a systematic review in May, 2013, which identified eight eligible randomised trials done between 2000 and 2013 of low-molecular weight heparin to prevent recurrent placenta-mediated pregnancy complications. We excluded studies on the basis of the wrong population, the study being ongoing, inability to confirm eligibility of participants, intervention stopped too early, and no response from the principal investigator. We requested individual patient data from the study authors for eligible women (women pregnant at the time of the study with a history of previous pregnancy that had been complicated by one or more of the following: pre-eclampsia, placental abruption, birth of an SGA neonate [<10th percentile], pregnancy loss after 16 weeks' gestation, or two losses after 12 weeks' gestation) and recoded, combined, and analysed the data for our meta-analysis. The primary outcome was a composite of early-onset (<34 weeks) or severe pre-eclampsia, birth of an SGA neonate (<5th percentile), late pregnancy loss (>=20 weeks' gestation), or placental abruption leading to delivery, assessed on an intention-to-treat basis. We assessed risk of bias with the Cochrane Risk of Bias tool. This study is registered with PROSPERO, number CRD42013006249. FINDINGS: We analysed data from 963 eligible women in eight trials: 480 randomly assigned to low-molecular-weight heparin and 483 randomly assigned to no low-molecular-weight heparin. Overall, the risk of bias was not substantial enough to affect decisions regarding trial inclusion. Participants were mostly white (795/905; 88%) with a mean age of 30.9 years (SD 5.0) and 403/963 (42%) had thrombophilia. In the primary analysis, low-molecular-weight heparin did not significantly reduce the risk of recurrent placenta-mediated pregnancy complications (low-molecular-weight heparin 62/444 [14%] versus no low molecular-weight heparin 95/443 (22%) absolute difference -8%, 95% CI -17.3 to 1.4, p=0.09; relative risk 0.64, 95% CI 0.36-1.11, p=0.11). We noted significant heterogeneity between single-centre and multicentre trials. In subgroup analyses, low-molecular-weight heparin in multicentre trials reduced the primary outcome in women with previous abruption (p=0.006) but not in any of the other subgroups of previous complications. INTERPRETATION: Low-molecular-weight heparin does not seem to reduce the risk of recurrent placenta-mediated pregnancy complications in at-risk women. However, some decreases in event rates might have been too small for the power of our study to explore. FUNDING: Canadian Institutes of Health Research. PMID- 27720499 TI - Trajectories of health-related quality of life among family caregivers of individuals with dementia: A home-based caregiver-training program matters. AB - : To determine distinct courses of change in health-related quality of life (HRQoL) among family caregivers of individuals with dementia and how participating in a home-based caregiver-training program affects the probability of belonging to each course. Sixty three caregivers were in the intervention group, and 66 caregivers were in the control group of a single-blinded randomized clinical trial. Two distinct trajectories of HRQoL were identified: a well functioning trajectory and a poor-functioning trajectory. Caregivers who received the training program were more likely than those who did not have a well functioning trajectory of HRQoL over 18 months. This trajectory included bodily pain (b = 1.02, odds ratio [OR] = 2.76), general health perception (b = 1.28, OR = 3.60), social functioning (b = 1.12, OR = 3.05), vitality (b = 1.51, OR = 4.49), general mental health (b = 1.08, OR = 2.94), and mental component summary (b = 1.27, OR = 3.55). Home-based caregiver training can be considered as part of the protocol for managing patients with dementia and their caregivers. TRIAL REGISTRATION NUMBER: NCT02667951. PMID- 27720501 TI - Putting negative attitudes on the agenda? Not Criminally Responsible Reform Act publicity and juror decision-making. AB - The current study examined the effect of publicity about Canada's recent Not Criminally Responsible (NCR) Reform Act - legislation surrounding accused in insanity cases that purportedly aims to enhance public safety - on juror decision making. In line with agenda-setting theory, we expected that NCR Reform Act publicity might reinforce certain fears about the insanity defence, dependent on whether it had either a positive or negative evaluative slant. Contrary to previous work on the insanity defence, participants in this study generally favoured a NCR verdict. The evaluative slant of the NCR publicity had no effect on verdict decisions or insanity defence attitudes, but there was a significant difference in participants' evaluations of the fairness of the Reform Act, such that those exposed to a positive or control article viewed the act as fairer than those exposed to a negative article. This study may aid future researchers in evaluating potential unintended consequences of the NCR Reform Act. PMID- 27720500 TI - Stimuli associated with the presence or absence of amphetamine regulate cytoskeletal signaling and behavior. AB - Drug-paired stimuli rapidly enlarge dendritic spines in the nucleus accumbens (NAcc). While increases in spine size and shape are supported by rearrangement of the actin cytoskeleton and facilitate the synaptic expression of AMPA-type glutamate receptors, it remains unclear whether drug-related stimuli can influence signaling pathways known to regulate these changes in spine morphology. These pathways were studied in rats trained on a discrimination learning paradigm using subcellular fractionation and protein immunoblotting to isolate proteins within dendritic spine compartments in the NAcc shell. An open field chamber was repeatedly associated with amphetamine in one group (Paired) and explicitly unpaired with amphetamine in another (Unpaired). Rats in a third group were exposed to the open field but never administered amphetamine (Control). When administered saline and returned to the open field one week later, Paired rats as expected displayed a conditioned locomotor response relative to rats in the other two groups. NAcc shell tissues were harvested immediately after this 30-minute test. Re-exposing Paired rats to the drug-paired excitatory context significantly decreased p-GluA2(S880), an effect consistent with reduced internalization of this subunit and increased spine proliferation in these rats. In contrast, re exposing Unpaired rats to the drug-unpaired context, capable of inhibiting conditioned responding in these animals, significantly decreased levels of both actin binding protein Arp2/3 and p-cofilin, consistent with spine volatility, shrinkage, and inhibition of spine proliferation in these rats. These findings show that contextual stimuli previously associated with either the presence or absence of amphetamine differentially regulate cytoskeletal signaling pathways in the NAcc. PMID- 27720502 TI - Focus on Autism Spectrum Disorder: Issues and Treatment Approaches. PMID- 27720503 TI - Severe Childhood Autism: The Family Lived Experience. AB - This research examined the experiences of families living with a child with severe autism. There is limited literature on the experiences of families when a child has severe autism as distinct from milder autism and includes the voices of multiple family members. Van Manen's phenomenological approach was used for data collection and analysis. This approach allowed for the use of innovative data sources, including unstructured individual and family interviews, observations, and family lifelines (a pictorial, temporal picture with comments of the families lives). This study included 29 interviews with 22 participants from 11 families. All data were creatively triangulated and interpreted. Six essential themes were identified. First, families experienced autism as mysterious and complex because it is an invisible and unpredictable condition with diagnostic challenges. Second, families described severe autism behaviors that often caused self-injury, harm to others and damaged homes. Third, profound communication deficits resulted in isolation between the family and child. Fourth, families discussed the unrelenting stress from lack of sleep, managing the child's developmental delays, coordinating and financing services, and concern for the child's future. Fifth, families described consequences of isolation from friends, school, the public, and health providers. Sixth, families portrayed their need for compassionate support and formed 'hybrid families' (nuclear, extended families and friends) to gain support. Study results can be utilized to educate nurses/other providers about the unique needs of families with children with severe autism and could influence health care policies to improve the care for families caring for children with severe autism. PMID- 27720504 TI - Some Reflections on Hypertension and Its Treatment. PMID- 27720505 TI - Comparison of the Efficacy and Safety of Fixed-dose S-Amlodipine/Telmisartan and Telmisartan in Hypertensive Patients Inadequately Controlled with Telmisartan: A Randomized, Double-blind, Multicenter Study. AB - PURPOSE: The objective of this study was to evaluate the efficacy and safety of the fixed-dose combination S-amlodipine plus telmisartan (S-AM/TEL) compared with TEL monotherapy in patients with hypertension inadequately controlled by TEL monotherapy. METHODS: this study was a randomized, multicenter, double-blind, parallel group, Phase III, 8-week clinical trial to compare the superiority of the S-AM/TEL 2.5/40-mg and S-AM/TEL 5/40-mg combinations with TEL 80-mg mono therapy. The primary end point was the change in the mean sitting diastolic blood pressure from baseline (week 0) after 8 weeks of therapy between treatment groups. FINDINGS: Of 325 patients screened, 183 were randomly assigned to 3 groups (61 in the S-AM/TEL 2.5/40-mg group, 60 in the S-AM/TEL 5/40-mg group, and 62 in the TEL 80-mg group). Mean (SD) age was 53.9 (7.5) years, and male patients comprised 87%. No significant differences were found among the 3 groups in baseline characteristics. The primary end points, the changes of mean (SD) diastolic blood pressure at week 8 from the baseline were -10.56 (7.23) mm Hg in the S-AM/TEL 2.5/40-mg group, -12.32 (9.23) mm Hg in the S-AM/TEL 5/40-mg group, and -2.44 (7.92) mm Hg in the TEL 80-mg group. Both the S-AM/TEL 2.5/40-mg group and the S-AM/TEL 5/40-mg group had a statistically superior hypotensive effect compared with the TEL 80-mg group (P < 0.0001 for both). For evaluation of the safety profile, the frequencies of adverse events (AEs) among the groups were also not significantly different (S-AM/TEL 2.5/40-mg group, 18.6%; S-AM/TEL 5/40 mg group, 20%; and TEL 80-mg group, 22.6%), and the incidences of AEs were not different among the groups. The most common AEs were respiratory disorders, followed by headache, dizziness, and peripheral edema. IMPLICATIONS: Treatment with S-AM/TEL 2.5/40 mg and S-AM/TEL 5/40 mg was superior to increasing the TEL dose in terms of hypotensive effect in patients with hypertension inadequately controlled by TEL monotherapy. S-AM/TEL fixed-dose combinations are an effective and tolerable option for patients inadequately responding to TEL monotherapy and also a good option for improving patients' medication adherence.

PMID- 27720506 TI - Effect of the premedication with oral clonidine on surgical comfort in patients undergoing fess due to advanced nasal polyposis: A randomized double blind clinical trial. AB - : OBJECTiVE: The objective of this randomized double blind study was to evaluate effect of the premedication with oral clonidine on blood pressure, cleaning of surgical site and bleeding in the ESS performed due to advanced NP. METHODS: A total of 52 patients who underwent functional endoscopic sinus surgery (FESS) due to Kennedy grade 4 nasal polyposis (NP) were included. Patients were randomized into two groups. Group 1 (n=26) received 0.2mg oral clonodine one hour before the operation in addition to standard anesthesia procedure. Group 2 (n=26) was administered standard anesthesia procedure alone. The amount of bleeding during surgery, cleaning of surgical site and surgeon's satisfaction were evaluated in comparison between the groups. RESULTS: The amount of bleeding and mean arterial pressure were significantly lower in the Group 1 compared to the Group 2. The cleaning of surgical site was found to be significantly better and surgeon's satisfaction significantly higher in the Group 1 than in the Group 2. Systolic, diastolic and mean arterial pressures during surgery were significantly lower in the Group 1 compared to the Group 2. CONCLUSION: Premedication with oral clonidine provides a clearer view of surgical site, reduces the amount of bleeding and significantly increases surgeon's satisfaction during the operation in FESS performed due to NP. Premedication with oral clonidine is a safe, inexpensive and effective methods in order to increase the surgical success and comfort and reduce complications in the FESS surgery.

PMID- 27720510 TI - Anterolateral femoral bowing and loss of thigh muscle are associated with occurrence of atypical femoral fracture: Effect of failed tension band mechanism in mid-thigh. AB - BACKGROUND: The purpose of this study was to characterize anterolateral bowing of the femur using X-rays and muscular atrophy in the mid-thigh using computed tomography (CT) in patients with atypical femoral fractures (AFFs). We then compared the results with those of an intertrochanteric fracture to understand whether these measures act as causative factors of AFFs. METHODS: From January 2009 to December 2015, 37 patients with complete AFF and 12 patients with incomplete AFF were enrolled in this study. Lateral femoral bowing, anterior femoral bowing, cross-sectional area (CSA), and attenuation coefficient of thigh muscles in the AFF group are measured and compare with those in the intertrochanteric fracture group. RESULTS: Lateral and anterior femoral bowing in the AFF group were significantly higher than those in the intertrochanteric fracture group. The level of fracture was found to be significantly associated with lateral and anterior femoral bowing (r = 0.569, r2 = 0.324, p < 0.001; r = 0.530, r2 = 0.281, p < 0.001, respectively). Total CSA and CSA of anterior and medial compartments were significantly lower in the AFF group (p < 0.05). The attenuation coefficient of the total thigh muscle and all three compartments in the AFF group were significantly lower than those in the intertrochanteric fracture group (p < 0.05). CONCLUSIONS: This study demonstrated that anterolateral femoral bowing and loss of thigh muscle were highly associated with the occurrence of AFFs. PMID- 27720511 TI - Prevalence of pincer, cam, and combined deformities in Japanese hip joints evaluated with the Japanese Hip Society diagnostic guideline for femoroacetabular impingement: A CT-based study. AB - BACKGROUND: Femoroacetabular impingement (FAI) is thought to be associated with hip osteoarthritis. We investigated the prevalences of radiologic deformities of the pincer, cam, and their combinations in Japanese hip joints using computed tomography (CT) according to the Japanese Hip Society diagnostic guideline for FAI. METHODS: Multi-slice CT images were evaluated. Pincer deformities were defined as: type 1: center-edge angle (CE) >=40 degrees ; type 2: CE >= 30 degrees and acetabular roof obliquity <=0 degrees ; type 3: CE >= 25 degrees and retroverted acetabulum. Cam deformities were defined as: type 1: CE >= 25 degrees , alpha-angle >=55 degrees , and head-neck offset ratio <0.14; type 2: CE >= 25 degrees , alpha-angle >=55 degrees , and herniation pit positive; type 3: CE >= 25 degrees , alpha-angle >=55 degrees , and pistol grip deformity positive. RESULTS: We studied 128 hips. Pincer was detected in 35.9% (type 1, 12.5%; type 2, 18.0%; type 3, 13.3%). Cam was detected in 24.2% (type 1, 23.4%; type 2, 7.8%; type 3, 10.9%). Combined deformities were detected in 10.2%. Type 3 pincer/type 1 cam was the most frequent combined deformity compared with all combined deformities. All of the cam deformities, total combined deformities, and all radiological FAIs appeared significantly more often in men. CONCLUSIONS: When we used this guideline to diagnose FAI in a Japanese population, radiological FAI was common, and pincer deformities were more common than cam deformities. The most frequent seen pincer, cam, and combined deformities was type 2 pincer, type 1 cam, and the combination of type 3 pincer/type 1 cam, respectively.

PMID- 27720512 TI - Incidence and survival of sebaceous carcinoma in the United States. AB - BACKGROUND: Information on risk factors, epidemiology, and clinical characteristics of sebaceous carcinoma (SC) is limited. OBJECTIVE: We sought to analyze trends in SC in the United States from 2000 through 2012. METHODS: We used data from the 18 registries of the Surveillance, Epidemiology, and End Results (SEER) Program from 2000 to 2012 to calculate the cause of death, relative frequencies/incidences, 5-/10-year Kaplan-Meier survival, hazard ratios, and incidence rates for SC. Each parameter was analyzed by age, location of occurrence (ocular/extraocular), race, sex, and SEER registry. RESULTS: Overall incidence was 0.32 (male) and 0.16 (female) per 100,000 person-years. Incidence significantly increased, primarily because of an increase among men. Incidence among whites was almost 3 times the rate among non-whites. Male sex (P < .0001), black race (P = .01), and extraocular anatomic location (P < .0001) were associated with significantly higher all-cause mortality. However, overall case specific mortality for SC decreased significantly. LIMITATIONS: Underregistration of patients in SEER registries, lack of verification of individual diagnoses, and low levels of staging data because of low stage-classification rate are limitations. CONCLUSIONS: The overall incidence of SC is increasing significantly. Male sex, black race, and extraocular occurrences are associated with significantly greater mortality. PMID- 27720514 TI - Do Changes in Patellofemoral Joint Offset Lead to Adverse Outcomes in Total Knee Arthroplasty With Patellar Resurfacing? A Radiographic Review. AB - BACKGROUND: Patellofemoral joint biomechanics contribute to anterior knee pain, instability, and dysfunction following total knee arthroplasty (TKA). Information about specific factors leading to anterior knee pain and dysfunction is currently limited. Changes in patellofemoral joint offset (PFO) refers to a mismatch between the preoperative and postoperative anteroposterior geometry of the patellofemoral joint. It remains unclear whether these changes lead to adverse outcomes in TKA. METHODS: A retrospective radiographic review of 970 knees pre TKA and post-TKA was completed to correlate the radiographic and clinical outcomes of changing the PFO using a posterior-stabilized single knee design with patellar resurfacing. RESULTS: A total of 970 patients were reviewed. Postoperatively, the anterior femoral offset, anteroposterior femoral size, and anterior patellar offset were changed in 40%, 60%, and 71% of knees, respectively, compared to preoperative values. The Western Ontario and McMasters Osteoarthritis Index total score as well as subscale scores for pain and function were not significantly affected by an increase or decrease in PFO. Similarly, Knee Society Scores and range of motion were not significantly affected. Increased anterior patellar offset was, however, associated with increased postoperative patellar tilt. Postoperative patellar tilt was not correlated with adverse patient satisfaction scores or loss of range of motion. CONCLUSION: Changes in PFO (decreased, maintained, or increased) are common post-TKA and are not associated with a difference in clinical outcomes. Increases in anterior patellar offset led to increased patellar tilt, which was not associated with adverse patient satisfaction scores. PMID- 27720515 TI - [Assessment of restrictive episiotomy use and impact on perineal tears in the Burgundy's Perinatal Network]. AB - OBJECTIVES: To analyse episiotomy and perineal tears rates in Burgundy after French National College of Obstetricians and Gynecologists (CNGOF) guidelines in 2005. MATERIALS AND METHOD: Multicenter retrospective study, between 2003-2005 (period 1) et 2012-2014 (period 2), conducted on singletons vaginal deliveries, in cephalic presentation from 37 weeks. We compared the episiotomy rate (ER), and perineal lesions in normal deliveries (ND) and instrumental deliveries (ID) between the two periods. RESULTS: A total of 74,268 women were included. The overall ER significantly decreased from 35.8 to 16.7% (P<0.01), without increasing third degree perineal tears (0.73% vs. 0.66%) or fourth degree (0.14% vs 0.14%). First degree perineal tears rose (42.1% vs 17.6%, P<0.001), second degree decreased (13.5% vs 20.5%, P<0.001). ER decreased whatever the level of motherhood, healthcare ward, vaginal delivery type, or the instrument used. CONCLUSION: Our study found a strong impact in Burgundy of the French guidelines for the practice of restrictive episiotomy for both ND and for ID without increasing sphincter tears and in decreasing spontaneous morbidity.

Development of maternity hospitals to make them accessible to spinal cord injured pregnant women to improve their care in pre-, per- and post-partum. METHODS: Cross-sectional declarative study based on a questionnaire distributed to health professionals in the maternity hospital of the University Hospital of Nantes and liberal midwives of Nantes conurbation, based on their knowledge, their difficulties and their expectations for obstetrical care for spinal cord injured women. An inventory was carried out in parallel at the maternity hospital of the University Hospital of Nantes. RESULTS: Seventy-two percent of health professionals surveyed rated their level of knowledge on spinal cord injuries insufficient or even non-existent. Among the professionals, 84.8% said they encountered difficulties to take care of spinal cord injured women. The main cited difficulty relates to unsuitable equipment or premises, obstacle indeed found during the inventory made on the maternity hospital. CONCLUSION: Several proposals are being considered, including specific trainings, the execution of a management protocol for spinal cord injured women, the establishment of a situation's form of handicap, the layout of the maternity hospitals premises, and finally, the creation of reference's centers in the region to optimize the follow-up of these patients.

PMID- 27720519 TI - Segmentation of Skin Tumors in High-Frequency 3-D Ultrasound Images. AB - High-frequency 3-D ultrasound imaging is an informative tool for diagnosis, surgery planning and skin lesion examination. The purpose of this article was to describe a semi-automated segmentation tool providing easy access to the extent, shape and volume of a lesion. We propose an adaptive log-likelihood level-set segmentation procedure using non-parametric estimates of the intensity distribution. The algorithm has a single parameter to control the smoothness of the contour, and we describe how a fixed value yields satisfactory segmentation results with an average Dice coefficient of D = 0.76. The algorithm is implemented on a grid, which increases the speed by a factor of 100 compared with a standard pixelwise segmentation. We compare the method with parametric methods making the hypothesis of Rayleigh or Nakagami distributed signals, and illustrate that our method has greater robustness with similar computational speed. Benchmarks are made on realistic synthetic ultrasound images and a data set of nine clinical 3-D images acquired with a 50-MHz imaging system. The proposed algorithm is suitable for use in a clinical context as a post-processing tool. PMID- 27720520 TI - Three-Dimensional Ultrasound-Guided Real-Time Midline Epidural Needle Placement with Epiguide: A Prospective Feasibility Study. AB - Current 2-D ultrasound technology is unable to perform a midline neuraxial needle insertion under real-time ultrasound guidance using a standard needle and without an assistant. The aim of the work described here was to determine the feasibility of a new technology providing such capability, starting with a study evaluating the selected puncture site. A novel 3-D ultrasound imaging technique was designed using thick-slice rendering in conjunction with a custom needle guide (3DUS + Epiguide). A clinical feasibility study evaluated the ability of 3DUS + Epiguide to identify the epidural needle puncture site for a midline insertion in the lumbar spine. We hypothesized that (i) the puncture site identified by 3DUS + Epiguide was within a 5-mm radius from the site chosen by standard palpation, and (ii) the difference between the two puncture sites was not correlated to the patient characteristics age, weight, height, body mass index and gestational age. The mean (+/-standard deviation) distances between puncture sites determined by 3DUS + Epiguide and palpation were 3.1 (+/-1.7) mm and 2.8 (+/-1.3) mm, for the L2-3 and L3-4 interspaces of 20 patients, respectively. Distances were comparable to intra-observer variability, indicating the potential for a thick-slice rendering of 3-D ultrasound along the Epiguide trajectory to select the puncture site of a midline neuraxial needle insertion. The long-term potential benefits of this system include increased efficiency and use of anesthesia, and a reduction in the frequency and severity of the complications from incorrect needle insertions. Epidural success in the most difficult cases (e.g., the obese) will be the focus of future work. PMID- 27720521 TI - A Novel Elastographic Frame Quality Indicator and its use in Automatic Representative-Frame Selection from a Cine Loop. AB - This study was aimed at developing a method for automatically selecting a few representative frames from several hundred axial-shear strain elastogram frames typically obtained during freehand compression elastography of the breast in vivo. This may also alleviate some inter-observer variations that arise at least partly because of differences in selection of representative frames from a cine loop for evaluation and feature extraction. In addition to the correlation coefficient and frame-average axial strain that have been previously used as quality indicators for axial strain elastograms, we incorporated the angle of compression, which has unique effects on axial-shear strain elastogram interpretation. These identified quality factors were computed for every frame in the elastographic cine loop. The algorithm identifies the section having N contiguous frames (N = 10) that possess the highest cumulative quality scores from the cine loop as the one containing representative frames. Data for total of 40 biopsy-proven malignant or benign breast lesions in vivo were part of this study. The performance of the automated algorithm was evaluated by comparing its selection against that by trained radiologists. The observer- identified frame that consisted of a sonogram, axial strain elastogram and axial-shear strain elastogram was compared with the respective images in the frames of the algorithm identified section using cross-correlation as a similarity measure. It was observed that there was, on average (~standard deviation), 82.2% (~2.2%), 83.4% (~3.8%) and 78.4% (~3.6%) correlation between corresponding images of the observer-selected and algorithm-selected frames, respectively. The results indicate that the automatic frame selection method described here may provide an objective way to select a representative frame while saving time for the radiologist. Furthermore, the frame quality metric described and used here can be displayed in real time as feedback to guide elastographic data acquisition and for training purposes. PMID- 27720522 TI - Fully Automated Muscle Ultrasound Analysis (MUSA): Robust and Accurate Muscle Thickness Measurement. AB - Musculoskeletal ultrasound imaging allows non-invasive measurement of skeletal muscle thickness. Current techniques generally suffer from manual operator dependency, while all the computer-aided approaches are limited to be semi automatic or specifically optimized for a single muscle. The aim of this study was to develop and validate a fully automatic method, named MUSA (Muscle UltraSound Analysis), for measurement of muscle thickness on longitudinal ultrasound images acquired from different skeletal muscles. The MUSA algorithm was tested on a database of 200 B-mode ultrasound images of rectus femoris, vastus lateralis, tibialis anterior and medial gastrocnemius. The automatic muscle thickness measurements were compared to the manual measurements obtained by three operators. The MUSA algorithm achieved a 100% segmentation success rate, with mean differences between the automatic and manual measurements in the range of 0.06-0.45 mm. MUSA performance was statistically equal to the operators and its measurement accuracy was independent of the muscle thickness value.

PMID- 27720524 TI - Depression and Functional Status Among African American Stroke Survivors in Inpatient Rehabilitation. AB - PURPOSE: To examine the prevalence of poststroke depression (PSD) among African American stroke survivors and the association of depression with functional status at inpatient rehabilitation facility (IRF) discharge. METHODS: Secondary data analysis was conducted of a patient cohort who received care at 3 IRFs in the United States from 2009 to 2011. Functional status was measured by the Functional Independence Measure (FIM). Multiple linear regression models were used to examine associations of PSD and FIM motor and cognitive scores. RESULTS: Of 458 African American stroke survivors, 48.5% were female, 84% had an ischemic stroke, and the mean age was 60.8 +/- 13.6 years. Only 15.4% (n = 71) had documentation of PSD. Bivariate analyses to identify factors associated with depression identified a higher percentage of patients with depression than without who were retired due to disability (17.1% versus 11.6%) or employed (31.4% versus 19.6%) prestroke (P = .041). Dysphagia, cognitive deficits, and a lower admission motor FIM score were also significantly more common among those with depression. There was no significant relationship between depression and functional status after adjusting for patient characteristics. CONCLUSIONS: In this study, 15% of the African Americans who received rehabilitation after a stroke had documentation of PSD but this was not associated with functional status at discharge. PMID- 27720525 TI - Predictive Value of Modifications of the Prehospital Rapid Arterial Occlusion Evaluation Scale for Large Vessel Occlusion in Patients with Acute Stroke. AB - BACKGROUND: Prehospital clinical scales to identify patients with acute stroke with a large vessel occlusion (LVO) and direct them to an endovascular-capable stroke center are needed. We evaluated whether simplification of the Rapid Arterial oCclusion Evaluation (RACE) scale, a 5-item scale previously validated in the field, could maintain its high performance to identify patients with LVO. METHODS: Using the original prospective validation cohort of the RACE scale, 7 simpler versions of the RACE scale were designed and retrospectively recalculated for each patient. National Institutes of Health Stroke Scale score and proximal LVO were evaluated in hospital. Receiver operating characteristic analysis was performed to test performance of the simplified versions to identify LVO. For each version, the threshold with sensitivity closest to the original scale (85%) was used, and the variation in specificity and correct classification were assessed. RESULTS: The study included 341 patients with suspected stroke; 20% had LVO. The 7 simpler versions of the RACE scale had slightly lower area under the curve for detecting LVO because of lower specificity at the chosen sensitivity level. Correct classification rate decreased 9% if facial palsy was simplified or if eye or gaze deviation was removed, and decreased 4.5% if the aphasia or agnosia cortical sign was removed. CONCLUSIONS: We recommend the original RACE scale for prehospital assessment of patients with suspected stroke for its ease of use and its high performance to predict the presence of a LVO. The use of simplified versions would reduce its predictive value. PMID- 27720526 TI - Histological Examination of Trousseau Syndrome-Related Thrombus Retrieved Through Acute Endovascular Thrombectomy: Report of 2 Cases. AB - The mechanism of thrombus formation in Trousseau syndrome remains unclear. The purpose of this study was to investigate specific pathological findings of the thrombi in Trousseau syndrome. The authors report on 2 cases of thrombi in Trousseau syndrome from large cerebral vessels removed by endovascular therapy and compared with thrombi in atherosclerosis or cardiac embolism. The first patient, a 67-year-old man, was transferred to our hospital for sudden onset consciousness disturbance and tetraparesis. He had been diagnosed with stage IV lung cancer. The magnetic resonance (MR) angiography demonstrated basilar artery occlusion. An endovascular thrombectomy was performed. The second patient, an 84 year-old woman, was transferred to our hospital for sudden onset motor aphasia and right-sided motor weakness. She has a history of stage IV pancreatic body cancer. The MR angiography demonstrated left middle cerebral artery occlusion. An endovascular thrombectomy was performed for the floating thrombus. Macroscopic findings of retrieved thrombi were observed immediately after thrombectomy. The thrombi in Trousseau syndrome were white in color and solid against manual compression, whereas thrombi from other causes were red and fragile. In terms of microscopic findings, the thrombi in Trousseau syndrome mainly contained fibrin. On the other hand, thrombi associated with atherosclerosis or cardiac embolism had smaller area of fibrin with a considerable amount of red and white blood cells. The thrombi in Trousseau syndrome, which caused occlusion of large cerebral vessel, almost exclusively consisted of fibrin. PMID- 27720527 TI - Climate influence on juvenile European sea bass (Dicentrarchus labrax, L.) populations in an estuarine nursery: A decadal overview. AB - Estuarine systems support the life cycle stages of commercially important marine fish and are influenced by large and local-scale climatic patterns. In this study, performed in the Mondego estuary, Portugal, we used an 11-year database (2003-2013) for analyzing the variability in the population of a marine juvenile migrant fish, the European sea bass Dicentrarchus labrax, regarding changes in abundance, population structure, growth rates, secondary production and annual day of peak abundance. Higher densities and production occurred in 2003, but no differences in 0-group growth could be observed. In order to detect change points in both biological and climatic data, the cumulative sum (CUSUM) of the deviations from the mean for the 2003-2013 period were determined for each parameter. The relationship between large and local-scale drivers and 0-group biological attributes were evaluated using a Spearman rank correlation analysis of CUSUM of biological and environmental data, considering the correspondent yearly values and with a time-lag of 1 year. The North Atlantic Oscillation (NAO) index, sea surface temperature (SST) and their respective winter values were tested as large-scale factors, while river runoff, salinity and estuarine water temperature were considered as local climate patterns. The significant factors explaining D. labrax 0-group abundance and production were salinity and the NAO, the latter being also a significant predictor considering the 1-year lag. The NAO with 1-year lag was also positively correlated with the day of peak abundance. The early stages of European sea bass were demonstrated to have a climate dependent life cycle, controlled by variations in both large-scale climatic patterns and local features. In southern European marine populations, the effects of the NAO seem less direct, and dependent on the magnitude of its expressions and on the time scale considered. PMID- 27720528 TI - Distinct community dynamics at two artificial habitats in a recreational marina. AB - Man-made facilities along coastlines modify water circulation and sedimentation dynamics which can affect the structure of marine benthic and pelagic communities. To test how environmental heterogeneity associated with a recreational marina affects the structure of the fouling community and the benthic-pelagic link, we conducted an experiment in which predation effects on recruitment and community structure were assessed in two artificial habitats: inside the marina, an area of calm waters and often disturbed by boating activity, and the breakwater, a more hydrodynamic area. Using visual censuses and video footages we also described the predation pressure and the identity of predators on the two areas. Inside the marina, the recruitment of ascidians and serpulids, but not of bryozoans, was restricted in some occasions, possibly due to reduced water circulation. Predation, mainly by the silver porgy fish Diplodus argenteus, reduced the survivor of didemnid ascidians on both areas, but predation intensity was 40 times higher in the breakwater than inside the marina. While the two artificial habitats did not necessarily support distinct communities, low recruitment coupled to weak predation inside the marina, a less dynamic environment, likely imply lower resilience and more susceptibility to disturbance. PMID- 27720529 TI - Publication Rates of Podium Versus Poster Presentations at the Arthroscopy Association of North America Meetings 2008-2012. AB - PURPOSE: To analyze the publication rate of poster and podium presentations at Arthroscopy Association of North America (AANA) annual meetings from 2008 to 2012. METHODS: An online search using PubMed and Google Scholar for all published manuscripts associated with abstracts presented from 2008 to 2012 AANA annual meetings was performed. Abstracts were classified by presentation type (poster vs podium), and the journal and publication date were recorded for all published abstracts. Descriptive statistics, logistic regression, and Fisher's exact tests were performed, with P < .05 considered significant. RESULTS: A total of 1,508 abstracts were submitted to AANA annual meetings from 2008 to 2012, with 976 abstracts accepted for presentation (65% overall acceptance rate). There were 328 podium (22% acceptance rate) and 648 poster (43% acceptance rate) presentations. Of the 976 accepted abstracts, 479 (49%) were published within 3 years in peer reviewed journals. The overall publication rates for podium and poster presentations were 59% (n = 193) and 44% (n = 286), respectively. Podium presentations were significantly more likely to be published within 3 years compared with poster presentations (P < .0001; odds ratio 1.8095, confidence interval 1.3826-2.3682). There were no differences in time to publication between podium and poster presentations (1.3 +/- 1.2 vs 1.1 +/- 1.3 years, P = .0633). Over the 5-year study period, the overall abstract acceptance rate (P < .0001) and the rate of abstracts accepted for poster presentation (P < .0001) increased significantly over time, whereas there was no increase in the rate of abstracts accepted for podium presentation (P = .5638). The most common journals of publication were Arthroscopy (n = 157, 32.7%) followed by American Journal of Sports Medicine (n = 93, 19.4%). CONCLUSIONS: The overall publication rate of abstracts presented at AANA annual meetings is 49%, with podium presentations 1.8 times more likely to be published than poster presentations. The overall abstract acceptance rate and the rate of abstracts accepted for poster presentation increased significantly over time, whereas there was no significant increase in the rate of abstracts accepted for podium presentation. CLINICAL RELEVANCE: The publication rates of abstracts presented at the AANA annual meetings demonstrate the meetings' impact and importance to the advancement of the scientific literature.

PMID- 27720532 TI - Setting an Agenda for Assessment of Health-related Quality of Life Among Men with Prostate Cancer on Active Surveillance: A Consensus Paper from a European School of Oncology Task Force. AB - BACKGROUND: Literature on the health-related quality of life (HRQoL) for men with localized prostate cancer (PCa) on active surveillance (AS) shows a need for methodological guidance regarding HRQoL issues and how to address them. OBJECTIVE: The European School of Oncology Task Force (ESO TF) aimed to identify a core set of research questions and related measures to include in AS HRQoL studies. DESIGN, SETTING, AND PARTICIPANTS: A modified Delphi study was used to reach consensus on AS HRQoL research topics and tools between 2014 and 2015. Data were collected by engaging a multidisciplinary team of 15 experts. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: An open-ended questionnaire was used to collect information from ESO TF members regarding issues in AS HRQoL research. Then a structured questionnaire was used to collect ratings on the usefulness/importance of different AS HRQoL aspects. Items that >=80% of ESO TF members rated as useful/important were retained. Items with a 50-80% rating were discussed to reach final agreement. RESULTS AND LIMITATIONS: Six main research questions concerning the selection of outcome measures, measurement tools, and comparison groups were identified as relevant. The core set of measures identified were related to individual characteristics, psychological dimensions; decision-making-related issues, and physical functioning. The multidisciplinary expertise of ESO TF members was a significant asset, even if bringing different backgrounds to the discussion table represented a challenge. CONCLUSIONS: HRQoL measures have to be sensitive to the specific needs of men on AS. The definition of HRQoL outcomes will enhance a broader understanding of the HRQoL of men on AS and sustain patient-centered medicine. PATIENT SUMMARY: An international panel agreed on a set of health-related quality-of-life aspects to be assessed among men on active surveillance for prostate cancer. Valid relevant questionnaires were identified. The experts' indications lay a foundation for future research and clinical practice. PMID- 27720531 TI - Focal High Intensity Focused Ultrasound of Unilateral Localized Prostate Cancer: A Prospective Multicentric Hemiablation Study of 111 Patients. AB - BACKGROUND: Up to a third of patients with localized prostate cancer have unilateral disease that may be suitable for partial treatment with hemiablation. OBJECTIVE: To evaluate the ability of high intensity focused ultrasound (HIFU) to achieve local control of the tumor in patients with unilateral localized prostate cancer. DESIGN, SETTING, AND PARTICIPANTS: The French Urological Association initiated a prospective IDEAL multi-institutional study (2009-2015), to evaluate HIFU-hemiablation as a primary treatment. INTERVENTION: Multiparametric magnetic resonance imaging and biopsy were used for unilateral cancer diagnosis and control, and HIFU-hemiablation. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary: absence of clinically significant cancer (CSC) on control biopsy at 1 yr (CSC: Gleason score >= 7 or cancer core length>3mm regardless of grade or > 2 positive cores). Secondary: presence of any cancer on biopsy, biochemical response, radical treatment free survival, adverse events, continence (no pad), erectile function (International Index of Erectile Function-5 >= 16), and quality of life (European Organization for Research and Treatment of Cancer QLQ-C28) questionnaires. RESULTS AND LIMITATIONS: One hundred and eleven patients were treated (mean age: 64.8 yr [standard deviation 6.2]; mean prostate-specific antigen: 6.2 ng/ml [standard deviation 2.6]; 68% low risk, 32% intermediate risk). Of the 101 patients with control biopsy, 96 (95%) and 94 (93%) had no CSC in the treated and contralateral lobes, respectively. Mean prostate-specific antigen at 2 yr was 2.3 ng/ml (standard deviation 1.7). The radical treatment free survival rate at 2 years was 89% (radical treatments: six radical prostatectomies, three radiotherapies, and two HIFU). Adverse events were Grade 3 in 13%. At 12 mo continence and erectile functions were preserved in 97% and 78%. No significant decrease in quality of life score was observed at 12 mo. One limitation is the number of low-risk patients included in this study. CONCLUSIONS: At 1 yr, HIFU-hemiablation was efficient with 95% absence of clinically significant cancer associated with low morbidity and preservation of quality of life. Radical treatment-free survival rate was 89% at 2 yr. PATIENT SUMMARY: This report shows that high intensity focused ultrasound half-gland treatment of unilateral prostate cancer provides promising results with high cancer control and low morbidity.

PMID- 27720534 TI - Systematic Review on the Fate of the Remnant Urothelium after Radical Cystectomy. AB - CONTEXT: Urothelial carcinoma is considered a pan-urothelial disease. As such, the remnant urothelium in the upper urinary tract and urethra following radical cystectomy (RC) remains at risk for secondary urothelial tumors (SUTs). OBJECTIVE: To describe the incidence, diagnosis, treatment, and outcomes of patients with SUTs after RC. EVIDENCE ACQUISITION: A systematic search was conducted using PubMed database according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines to identify studies between 1970 and 2016 reporting on malignant diseases of the urothelium after RC for bladder cancer. The search strategy separated between upper and lower tract urothelial tumors. EVIDENCE SYNTHESIS: Of a total of 1069 studies, 57 were considered for evidence synthesis. SUTs occured in approximately 4-10% of patients after RC. Carcinoma in situ of the bladder, a history of nonmuscle invasive bladder cancer, and tumor involvement of the distal ureter are the strongest risk factors for secondary upper tract tumors. Risk factors for secondary urethral tumors represent urothelial malignancy in the prostatic urethra/prostate and bladder neck (in women), nonorthotopic diversions, and positive findings on permanent sections. The majority of patients (84%) with SUTs, presented with urothelial recurrence without evidence of metastasis. Of those, 84.0% were treated with surgery, 10.5% with systemic chemotherapy and/or radiotherapy, and 5.6% with topical chemotherapy and/or immunotherapy. After a median follow-up of 91 mo (range: 26-155), 65.9% of patients died of disease and 21.5% died of other causes. Detection and treatment of SUTs at an asymptomatic stage can reduce the risks of cancer-specfific and overall mortality by 30%. A limitation of the study is that the available data were retrospective. CONCLUSIONS: SUTs are rare oncological events and most patients have an adverse prognosis despite absence of distant disease at diagnosis. Therefore, surveillance of the remnant urothelium should be implemented for patients with histological features of panurothelial disease as it may improve timely detection and treatment. PATIENT SUMMARY: Secondary tumors of the renal pelvis, ureters, and urethra occur in approximately 4-10% of patients after radical removal of the bladder for bladder cancer. These patients' prognoses are reduced, likely due to delayed diagnosis. Therefore, routine surveillance might be important to detect tumors at an early stage. PMID- 27720536 TI - Pathophysiology and Contributing Factors in Postprostatectomy Incontinence: A Review. AB - CONTEXT: The incidence and awareness of postprostatectomy incontinence (PPI) has increased during the past few years, probably because of an increase in prostate cancer surgery. Many theories have been postulated to explain the pathophysiology of PPI. OBJECTIVE: The current review scrutinizes various pathophysiologic mechanisms underlying the occurrence of PPI. EVIDENCE ACQUISITION: A search was conducted on PubMed and EMBASE for publications on PPI. The primary search returned 2518 publications. Animal and basic research studies, letters, publications on prostatectomy for benign reasons, pathology of prostatic carcinoma, radiotherapy and hormone therapy of prostatic carcinoma, and review articles were all used as criteria for exclusion from the study. A total of 128 publications were selected for final analysis. EVIDENCE SYNTHESIS: Neuromuscular anatomic elements and pelvic support are known to influence PPI as evidenced by multiple publications. A number of non-anatomic and surgical elements have been postulated as contributing factors to PPI. Biological factors and preoperative parameters include: functional bladder changes, age, body mass index (BMI), pre existing lower urinary tract symptoms (LUTS), prostate size, and oncologic factors. Multiple studies reported the impact of specific anatomic/surgical factors, including fibrosis, shorter membranous urethral length (MUL), anastomotic stricture, damage to the neurovascular bundle, and extensive dissection, all of which have a negative impact on the continence status of patients following radical prostatectomy (RP). Investigation of the impact of techniques to spare the bladder neck and additional procedures to reconstruct the posterior or anterior support structures (eg, the Rocco stitch) on continence status is ongoing. CONCLUSIONS: Anatomic support and pelvic innervation appear to be important factors in the etiology of PPI. Biological/preoperative factors including greater age at time of surgery, pre-existing LUTS, high BMI, shorter MUL, and functional bladder changes have a negative impact on continence after RP. Extensive dissection during surgery, damage to the neurovascular bundle, and postoperative fibrosis also have a substantial negative impact on the continence status of men undergoing RP. Sparing of the bladder neck and anterior fixation of the bladder-urethra anastomosis are associated with better continence rates. There is still debate about whether posterior pelvic reconstruction leads to better postoperative continence rates. PATIENT SUMMARY: Radical prostatectomy is an oncologic procedure and thus requires removal of the entire prostate gland and seminal vesicles, ideally with negative surgical margins. This sometimes results in urinary incontinence. The factors contributing to urinary incontinence are explained in this article.

AB - BACKGROUND: Early detection and treatment of asymptomatic men with advanced and high-risk prostate cancer (PCa) may improve survival rates. OBJECTIVE: To determine outcomes for men diagnosed with advanced PCa following prostate specific antigen (PSA) testing who were excluded from the ProtecT randomised trial. DESIGN, SETTING, AND PARTICIPANTS: Mortality was compared for 492 men followed up for a median of 7.4 yr to a contemporaneous cohort of men from the UK Anglia Cancer Network (ACN) and with a matched subset from the ACN. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: PCa-specific and all-cause mortality were compared using Kaplan-Meier analysis and Cox's proportional hazards regression. RESULTS AND LIMITATIONS: Of the 492 men excluded from the ProtecT cohort, 37 (8%) had metastases (N1, M0=5, M1=32) and 305 had locally advanced disease (62%). The median PSA was 17MUg/l. Treatments included radical prostatectomy (RP; n=54; 11%), radiotherapy (RT; n=245; 50%), androgen deprivation therapy (ADT; n=122; 25%), other treatments (n=11; 2%), and unknown (n=60; 12%). There were 49 PCa specific deaths (10%), of whom 14 men had received radical treatment (5%); and 129 all-cause deaths (26%). In matched ProtecT and ACN cohorts, 37 (9%) and 64 (16%), respectively, died of PCa, while 89 (22%) and 103 (26%) died of all causes. ProtecT men had a 45% lower risk of death from PCa compared to matched cases (hazard ratio 0.55, 95% confidence interval 0.38-0.83; p=0.0037), but mortality was similar in those treated radically. The nonrandomised design is a limitation. CONCLUSIONS: Men with PSA-detected advanced PCa excluded from ProtecT and treated radically had low rates of PCa death at 7.4-yr follow-up. Among men who underwent nonradical treatment, the ProtecT group had a lower rate of PCa death. Early detection through PSA testing, leadtime bias, and group heterogeneity are possible factors in this finding. PATIENT SUMMARY: Prostate cancer that has spread outside the prostate gland without causing symptoms can be detected via prostate-specific antigen testing and treated, leading to low rates of death from this disease. PMID- 27720541 TI - The pathways of genetic transformation in cholangiocarcinogenesis. AB - Cholangiocarcinoma (CCA) is an aggressive malignancy that originates from the epithelial cells of the biliary duct system. Depending on the anatomical location, CCA can be considered extrahepatic (eCCA) or intrahepatic (iCCA) (1). Two thirds of CCAs involve the extrahepatic biliary system, whereas the rest are confined within the liver parenchyma, beyond the secondary biliary radicals (2). Due to its biological aggressiveness and difficulty in diagnosis, the majority of patients with CCA are unresectable at presentation and the overall 5-year survival is approximately five percent (4). This article focuses on the genetic and epigenetic alterations present in cholangiocarcinomas, their occasional relationship to external stimuli, and with an emphasis on those unanswered questions about cholangiocarcinogenesis and future directions in the comprehension of epigenetic DNA methylation in patients with CCA. PMID- 27720540 TI - Best Clinical Practice: Current Controversies in Pulmonary Embolism Imaging and Treatment of Subsegmental Thromboembolic Disease. AB - BACKGROUND: Pulmonary embolism (PE) affects >600,000 patients per year in the United States. Evaluation includes clinical decision rules, laboratory tests, and several imaging modalities. The diagnosis of PE has risen in recent years, particularly subsegmental PE (SSPE). Controversy exists concerning the diagnosis and treatment of these lesions. OBJECTIVE: We sought to provide emergency physicians with a review of the controversies surrounding PE testing and the diagnosis and treatment of SSPE. DISCUSSION: With the rise of computed tomography (CT) testing for PE, diagnosis has increased. Providers often omit risk stratification in favor of D-dimer or imaging, which does not have literature support. The detection of PE has risen by 80%, and this increased testing is associated with several risks, including contrast reaction, nephropathy, and increased radiation. SSPE diagnosis has risen with improved imaging technology, but the literature shows low interobserver agreement with diagnosis of true SSPE. Studies disagree on the clinical significance and dangers of this PE subset. The American College of Chest Physicians 2016 guidelines recommend withholding anticoagulation for SSPE with low risk for recurrent thrombus and no concurrent deep vein thrombosis. Patients at high risk for recurrent venous thromboembolism or with deep vein thrombosis warrant anticoagulation. The provider is ultimately responsible for appropriate evaluation with risk stratification and selective testing. CONCLUSIONS: SSPE presents a quandary, because the literature differs in showing harm despite increased diagnosis. American College of Chest Physicians guidelines for the treatment of SSPE take into account the patient, the imaging, and other imaging modalities. Providers should use risk stratification with shared decision-making in the evaluation and treatment of SSPE.

AB - The uptake and metabolism of ibuprofen (IBU) by plants at the cellular level was investigated using a suspension culture of A. thaliana. Almost all IBU added to the medium (200 MUM) was metabolized or bound to insoluble structures in 5 days. More than 300 metabolites were determined by liquid chromatography-high resolution mass spectrometry (LC-HRMS) analysis, and most of these are first reported for plants here. Although hydroxylated derivatives formed by oxidation on the isobutyl side chain were the main first-step products of IBU degradation, conjugates of these products with sugar, methyl and amino acid groups were the dominant metabolites in the culture. The main portion of total added IBU (81%) was accumulated in the extractable intracellular pool, whereas the cultivation medium fraction contained only 19%. The amount of the insoluble cell-wall-bound IBU was negligible (0.005% of total IBU). PMID- 27720544 TI - Phosphorus leakage from fisheries sector - A case study in Thailand. AB - Although phosphorus (P) is an essential element needed for all lives, excess P can be harmful to the environment. The objective of this study aims to determine P flows in the fisheries sector of Thailand consisting of both sea and freshwater activities of captures and cultures. Currently, the annual fisheries catch averages 3.44 +/- 0.50 Mt. Most comes from marine capture 1.95 +/- 0.46 Mt, followed by coastal aquaculture 0.78 +/- 0.09 Mt, freshwater aquaculture 0.49 +/- 0.05 Mt, and inland capture 0.22 +/- 0.01 Mt. Of this total, about 11% is contained in fresh products directly sold in local markets for consumption, while 89% is sent to processing factories prior to being sold in local markets and exported. The quantities of P entering the fisheries sector come from captures, import of fisheries products and feed produced from agriculture. This P input to the fisheries sector is found to average 28,506 t P.y-1 based on the past ten year records. Of this total, P input from captures accounts for 76%; while, 11% represents aquatic feeds from agriculture and animal manures. About 13% is obtained from the imports of fishery products. Coastal and freshwater aquacultures are found to be P consumers because their feeds are almost all produced from agricultural crops grown inland. Moreover, these activities cause most of P losses, approximately 10,188 t P.y-1, which account for 89% of the total P loss from the fisheries sector. Overall, P in the fisheries sector is found to mobilize through three channels: (a) 44% is consumed within the country; (b) about 16% is exported; and, (c) 40% is lost from the ecosystem. Based on the results of this work it is recommended that future research be directed on ways to minimize P loss and maximize P recycle in Thailand's fisheries sector as to enhance its food security and curtail water pollution.

We investigated the agglomeration of 14C-labeled few-layer graphene (FLG) at concentrations spanning nearly four orders of magnitude (2 MUg/L to 10 mg/L) using dynamic light scattering and sedimentation measurements. FLG agglomerates formed rapidly in deionized water at concentrations >3 mg/L. From 1 mg/L to 3 mg/L, salt-induced agglomeration was decreased with dilution of FLG suspensions; the critical coagulation concentration of the more concentrated suspension (3 mg/L) was significantly lower than the dilute suspension (1 mg/L) in the presence of NaCl (1.6 mmol/L and 10 mmol/L, respectively). In contrast, FLG underwent slow agglomeration and settling at concentrations <=0.1 mg/L in NaCl solutions and ambient waters with low ionic strength (<10 mmol/L). FLG nanoparticles with smaller lateral sizes (25 nm-75 nm) were shown to agglomerate more slowly than larger FLG, and these small FLG particles exhibited greater bioaccumulation in zebrafish embryo and stronger chorion penetration ability than larger FLG particles. These findings suggest that FLG at more environmentally relevant concentration is relatively stable and may have implications for exposure of small FLG to ecological receptors.

AB - This paper is a part of a multi-disciplinary research "Application of Decentralized On-Site Water Treatment System in Egypt for Use in Agriculture and Producing Safe Fish and Animal Proteins". The project aimed to investigate the environmental impact of implementing sewage water before and after treatment using the effluent of the on-site decentralized Japanese' Johkasou system, in agriculture and producing fish protein. The aim is to establish such system in Egypt to strengthen the sanitary conditions of water resources. In the present study, the impact of the sewage pollution in some fish farms at El-Fayyum, Port Said and El-Dakahlia governorates in Egypt was carried out. Water and fish (Oreochromis niloticus and Mugil cephalus) samples were collected from private fish farms of such localities. Bacteriological and chemical examination of water samples revealed the existence of coliforms and many other bacterial species of significant human health hazards. The chemical parameters of water showed a marked deviation from normal levels while examination of fish flesh specimens indicated contamination with Streptococcus Sp., Staphylococcus Sp., and Salmonella in all examined localities. Other bacterial isolates of human health importance (Morganella morganii, Pseudomonas cepacia and Enterococcos durans) were identified. The parasitological examination revealed the presence of encysted metacercariae (EMC); Diplostomatidae, Prohemistomatidae and Heterphyidae. Moreover, two protozoan parasites (Mxyoboulus tilapiae and Ichthyophthirius multifilis) were also recorded. The histopathological examination revealed mild tissue reaction in case of bacterial infection and severe pathological lesions in different organs in case of EMC infection. Lamellar hyperplasia and mononuclear cell infiltration in branchial tissue was common findings. In skeletal muscles, atrophy of muscle fibres, myolysis and myophagia were detected.

AB - Previous studies have shown that biochar enhances microbial reduction of iron (Fe) oxyhydroxide under anaerobic incubation. However, there is a lack of data on its influence on arsenic (As) release from As-contaminated paddy soils. In this study, paddy soil slurries (120 mg As kg-1) were incubated under anaerobic conditions for 60 days with and without the addition of biochar (3%, w/w) prepared from rice straw at 500 degrees C. Arsenic release, Fe reduction, and As fractionation were determined at 1, 10, 20, 30, and 60 d, while Illumina sequencing and real-time PCR were used to characterize changes in soil microbial community structure and As transformation function genes. During the first month of incubation, As released into soil solution increased sharply from 27.9 and 55.9 to 486 and 630 MUg kg-1 in unamended and biochar amended slurries, with inorganic trivalent As (AsIII) being the dominant specie (52.7-91.0% of total As). Compared to unamended slurries, biochar addition increased As and ferrous ion (Fe2+) concentrations in soil solution but decreased soil As concentration in the amorphous Fe/Al oxide fraction (F3). Difference in released As between biochar and unamended treatments (DeltaAs) increased with incubation time, showing strong linear relationships (R2 = 0.23-0.33) with DeltaFe2+ and DeltaF3, confirming increased As release due to enhanced Fe reduction. Biochar addition increased the abundance of Fe reducing bacteria such as Clostridum (27.3% vs. 22.7%), Bacillus (3.34% vs. 2.39%), and Caloramator (4.46% vs. 3.88%). In addition, copy numbers in biochar amended slurries of respiratory As reducing (arrA) and detoxifying reducing genes (arsC) increased 19.0 and 1.70 fold, suggesting microbial reduction of pentavalent As (AsV) adsorbed on Fe oxides to AsIII, further contributing to increased As release. PMID- 27720547 TI - Hyperspectral leaf reflectance of Carpinus betulus L. saplings for urban air quality estimation. AB - In urban areas, the demand for local assessment of air quality is high. The existing monitoring stations cannot fulfill the needs. This study assesses the potential of hyperspectral tree leaf reflectance for monitoring traffic related air pollution. Hereto, 29 Carpinus betulus saplings were exposed to an environment with either high or low traffic intensity. The local air quality was estimated by leaf saturation isothermal remanent magnetization (SIRM). The VIS NIR leaf reflectance spectrum (350-2500 nm) was measured using a handheld AgriSpec spectroradiometer (ASD Inc.). Secondary, leaf chlorophyll content index (CCI), specific leaf area (SLA) and water content (WC) were determined. To gain insight in the link between leaf reflectance and air quality, the correlation between SIRM and several spectral features was determined. The spectral features that were tested are plain reflectance values, derivative of reflectance, two band indices using the NDVI formula and PCA components. Spectral reflectance for wavelength bands in the red and short wave IR around the red edge, were correlated to SIRM with Pearson correlations of up to R = -0.85 (R2 = 0.72). Based on the spectral features and combinations thereof, binomial logistic regression models were trained to classify trees into high or low traffic pollution exposure, with classification accuracies up to 90%. It can be concluded that hyperspectral reflectance of C. betulus leaves can be used to detect different levels of air pollution within an urban environment. PMID- 27720548 TI - Synthesis, structure determination, and biological evaluation of phenylsulfonyl hydrazide derivatives as potential anti-inflammatory agents. AB - In our previous research, a novel series of phenylsulfonyl hydrazide derivatives were found to reduce LPS-induced PGE2 levels in RAW 264.7 macrophage cells via an inhibition of mPGES-1 enzyme. Recently, it was found that a regioisomeric mixture of phenylsulfonyl hydrazide was formed depending on the reaction conditions, which favor either of two regioisomers. One regioisomer corresponds to a kinetic product (7a-7c) and the other regioisomer corresponds to a thermodynamic product (8a-8c). Among them, the structure of kinetic product 7b was confirmed by measuring single X-ray crystallography. In vitro PGE2 assay studies showed that the kinetic product (7a and 7b; IC50=0.69 and 0.55MUM against PGE2) is generally more potent than the thermodynamic product (8a and 8b; IC50=>10 and 0.79MUM against PGE2). A molecular docking study also exhibited that the kinetic product (7a) has a higher MolDock Score (-147.4) than that of 8a (-142.4), which is consistent with the PGE2 assay results. A new potent phenylsulfonyl hydrazide (7d; IC50=0.06MUM against PGE2) without affecting COX-1 and COX-2 enzyme activities was identified based on these overall results.

AB - Monocyclic analog of neuroexcitatory neodysiherbaine has been designed and stereoselectively synthesized in 0.40% yield over total 24 steps starting from d ribose, by employing domino aldol-Cannizzaro reaction and stereoselective aldol reaction for construction of two quaternary carbon stereogenic centers at C4 and C6 positions, respectively. The hyperactivity of neodysiherbaine in mice was found to deteriorate in the novel analog, upon intracerebroventricular injection. PMID- 27720551 TI - Associations with Retinal Pigment Epithelium Thickness Measures in a Large Cohort: Results from the UK Biobank. AB - PURPOSE: To describe associations of ocular and systemic factors with retinal pigment epithelium (RPE)-Bruch's membrane (BM) complex thickness as measured by spectral-domain (SD) optical coherence tomography (OCT). DESIGN: Multisite community-based study. This research has been conducted using the UK Biobank Resource. PARTICIPANTS: Sixty-seven thousand three hundred eighteen people 40 to 69 years old received questionnaires, physical examination, and eye examination, including macular SD OCT. Systematic selection process identified 34 652 eyes with high-quality SD OCT images from normal individuals for analysis. METHODS: We included people with no self-reported ocular disease, diabetes, or neurologic disorders; visual acuity of >=20/25; refraction between -6 diopters (D) to 6 D, and IOP of 6 to 21 mmHg. Only high-quality, well-centered SD OCT images with central, stable fixation were included. Descriptive statistics, t tests, and regression analyses were performed. Multivariate regression modeling was used to adjust for covariates and to identify relationships between RPE-BM thickness and ocular and systemic features. MAIN OUTCOME MEASURES: Retinal pigment epithelium BM thickness, as measured by SD OCT segmentation using Topcon Advanced Boundary Segmentation at 9 Early Treatment of Diabetic Retinopathy Study subfields. RESULTS: Mean RPE-BM thickness was 26.3 MUm (standard deviation, 4.8 MUm) at central subfield. Multivariate regression with age stratification showed that RPE thinning became apparent after age 45. Among those aged <=45, RPE-BM was significantly thicker among those of black or mixed/other race (+3.61 and +1.77 MUm vs. white, respectively; P < 0.001) and higher hyperopia (+0.4 MUm/D; P < 0.001), but not for other variables considered. Among those age >45, RPE-BM was significantly thinner with older age (-0.10 MUm/year; P < 0.001), Asian ethnicity (-0.45 MUm vs. white; P = 0.02), taller height (-0.02 MUm/cm; P < 0.001), higher IOP (-0.03 MUm/mmHg; P < 0.001), and regular smoking (-0.27 MUm vs. nonsmokers; P = 0.02). In contrast, RPE-BM was significantly thicker among black or mixed/other race (+3.29 MUm and +0.81 MUm vs. white, respectively; P < 0.001) and higher hyperopia (+0.28 MUm/D; P < 0.001). There was no significant association with sex or Chinese ethnicity. CONCLUSIONS: We describe novel findings of RPE-BM thickness in normal individuals, a structure that varies with age, ethnicity, refraction, IOP, and smoking. The significant association with IOP is especially interesting and may have relevance for the etiology of glaucoma, while the association between age and smoking may have relevance for the etiology of age-related macular degeneration. PMID- 27720553 TI - Illuminating the lifecourse of place in the longitudinal study of neighbourhoods and health. AB - Place and health are inextricably entwined. Whilst insights have been gained into the associations between places, such as neighbourhoods, and health, the understanding of these relationships remains only partial. One of the reasons for this relates to time and change and the inter-relationships between the dynamic nature of both neighbourhoods and health. This paper argues that the lifecourse of place can be used as a conceptual framework to understand the evolution and ongoing development of neighbourhoods, and their impact on the geographies of health, past, present and future. Moreover, this paper discusses the capacity of a longitudinal form of enquiry - latent transition analysis - that is able to operationalise conceptual models of the lifecourse of place. To date, latent transition analysis has not been applied to the study of neighbourhoods and health. Drawing on research across a range of disciplines including developmental psychology, sociology, geography and epidemiology, this paper also considers praxis-based implications and recommendations for applications of latent transition analysis that aim to advance understanding of how neighbourhoods affect health in and over time.

PMID- 27720550 TI - IGF-I in the clinics: Use in retinopathy of prematurity. AB - Retinopathy of prematurity is a potentially blinding disease, which is associated with low neonatal IGF-I serum concentrations and poor growth. In severe cases impaired retinal vessel growth is followed by pathologic neovascularization, which may lead to retinal detachment. IGF-I may promote growth even in catabolic states. Treating preterm infants with recombinant human (rh) IGF-I to concentrations normally found during gestation has been suggested to have a preventative effect on ROP. A recent phase 2 study treating infants (gestational age between 23weeks+0days and 27weeks +6days) with rhIGF-I/IGF binding protein-3 until 30 postmenstrual weeks showed no effect on ROP but a 53% reduction in severe bronchopulmonary dysplasia and 44% reduction in severe intraventricular hemorrhage. Oxygen is a major risk factor for ROP and during the phase 2 study oxygen saturation targets were increased to 90-95%, due to national guidelines, which might have affected ROP rate and severity making increased IGF-I a weaker preventative factor for ROP. PMID- 27720552 TI - Aqueous Chlorhexidine for Intravitreal Injection Antisepsis: A Case Series and Review of the Literature. AB - PURPOSE: To determine the incidence of endophthalmitis in a large clinical series using aqueous chlorhexidine for antisepsis before intravitreal injection and to review the ophthalmic literature regarding chlorhexidine efficacy and safety. DESIGN: Multicenter retrospective case series. PARTICIPANTS: All patients receiving intravitreal injections from 7 retinal specialists. METHODS: An audit of intravitreal injections performed by retinal specialists who exclusively used aqueous chlorhexidine 0.05% or 0.1% for prophylaxis of infective endophthalmitis was undertaken. The incidence of endophthalmitis was determined from August 1, 2011, to February 28, 2015. A literature review was performed to critically appraise the ocular safety and efficacy of aqueous chlorhexidine. MAIN OUTCOME MEASURES: Incidence of endophthalmitis after intravitreal injections. RESULTS: A total of 40 535 intravitreal injections were performed by 7 retinal specialists across 3 centers. Chlorhexidine was well tolerated, and only 1 patient with a suspected allergic reaction was noted. Three cases of endophthalmitis were identified with 1 culture-positive case. The 0.0074% (1 in 13 512) per-injection rate of endophthalmitis in this series compares favorably with previous series in which povidone-iodine has been used. CONCLUSIONS: Aqueous chlorhexidine was associated with a low rate of postinjection endophthalmitis and was well tolerated by patients. PMID- 27720555 TI - Structure-based design of ester compounds to inhibit MLL complex catalytic activity by targeting mixed lineage leukemia 1 (MLL1)-WDR5 interaction. AB - WDR5 is an essential protein for enzymatic activity of MLL1. Targeting the protein-protein interaction (PPI) between MLL1 and WDR5 represents a new potential therapeutic strategy for MLL leukemia. Based on the structure of reported inhibitor WDR5-0103, a class of ester compounds were designed and synthetized to disturb MLL1-WDR5 PPI. These inhibitors efficiently inhibited the histone methyltransferase activity in vitro. Especially, WL-15 was one of the most potent inhibitors, blocking the interaction of MLL1-WDR5 with IC50 value of 26.4nM in competitive binding assay and inhibiting the catalytic activity of MLL1 complex with IC50 value of 5.4MUM. Docking model indicated that ester compounds suitably occupied the central cavity of WDR5 protein and recapitulated the interactions of WDR5-0103 and the hydrophobic groups and key amino greatly increased the activity in blocking MLL1-WDR5 PPI. PMID- 27720556 TI - Insights into tyrosinase inhibition by compounds isolated from Greyia radlkoferi Szyszyl using biological activity, molecular docking and gene expression analysis. AB - Greyia radlkoferi ethanol extract and its five compounds were tested for their inhibitory activity against the mushroom tyrosinase enzyme and melanin production on melanocytes. The crude extract showed significant tyrosinase inhibition with IC50 of 17.96MUg/ml. This is the first report of the isolation of these 5 compounds from Greyia radlkoferi. 2',4',6'-Trihydroxydihydrochalcone showed the highest tyrosinase inhibition at 17.70MUg/ml (68.48MUM), with low toxicity when compared with crude extract. This compound is therefore, a key component in the crude extract, which is responsible for tyrosinase inhibitory activity. The RT qPCR indicated that the mechanism of action is most likely post transcriptional. Further, the molecular docking study showed that tyrosinase inhibitory activity depends on interaction of the compound with Cu2+ ions at the active site. This is the first report of the tyrosinase inhibitory activity of the G. radlkoferi extract and molecular insights on interaction of its compounds with Cu2+ ions as the driving factor for tyrosinase inhibition. These results suggest that the extract of G. radlkoferi and the compound 2',4',6'-trihydroxydihydrochalcone have great potential to be further developed as pharmaceutical or cosmetic agents for use against dermatological disorders associated with melanin.

AB - Protein lysine methyltransferase G9a is widely considered as an appealing antineoplastic target. Herein we present an integrated workflow combining shape based virtual screening and structure-based molecular modification for the identification of novel G9a inhibitors. The shape-based similarity screening through ROCS overlay on the basis of the structure of UNC0638 was performed to identify CPUY074001 contained a 6H-anthra[1,9-cd]isoxazol-6-one scaffold as a hit. Analysis of the binding mode of CPUY074001 with G9a and 3D-QSAR results, two series compounds were designed and synthesized. The derivatives were confirmed to be active by in vitro assay and the SAR was explored by docking stimulations. Besides, several analogues showed acceptable anti-proliferative effects against several cancer cell lines. Among them, CPUY074020 displayed potent dual G9a inhibitory activity and anti-proliferative activity. Furthermore, CPUY074020 induced cell apoptosis in a dose-dependent manner and displayed a significant decrease in dimethylation of H3K9. Simultaneously, CPUY074020 showed reasonable in vivo PK properties. Altogether, our workflow supplied a high efficient strategy in the identification of novel G9a inhibitors. Compounds reported here can serve as promising leads for further study. PMID- 27720558 TI - Critical Review of Current Approaches for Echocardiographic Reproducibility and Reliability Assessment in Clinical Research. AB - BACKGROUND: There is no broadly accepted standard method for assessing the quality of echocardiographic measurements in clinical research reports, despite the recognized importance of this information in assessing the quality of study results. METHODS: Twenty unique clinical studies were identified reporting echocardiographic data quality for determinations of left ventricular (LV) volumes (n = 13), ejection fraction (n = 12), mass (n = 9), outflow tract diameter (n = 3), and mitral Doppler peak early velocity (n = 4). To better understand the range of possible estimates of data quality and to compare their utility, reported reproducibility measures were tabulated, and de novo estimates were then calculated for missing measures, including intraclass correlation coefficient (ICC), 95% limits of agreement, coefficient of variation (CV), coverage probability, and total deviation index, for each variable for each study. RESULTS: The studies varied in approaches to reproducibility testing, sample size, and metrics assessed and values reported. Reported metrics included mean difference and its SD (n = 7 studies), ICC (n = 5), CV (n = 4), and Bland Altman limits of agreement (n = 4). Once de novo estimates of all missing indices were determined, reasonable reproducibility targets for each were identified as those achieved by the majority of studies. These included, for LV end-diastolic volume, ICC > 0.95, CV < 7%, and coverage probability > 0.93 within 30 mL; for LV ejection fraction, ICC > 0.85, CV < 8%, and coverage probability > 0.85 within 10%; and for LV mass, ICC > 0.85, CV < 10%, and coverage probability > 0.60 within 20 g. CONCLUSIONS: Assessment of data quality in echocardiographic clinical research is infrequent, and methods vary substantially. A first step to standardizing echocardiographic quality reporting is to standardize assessments and reporting metrics. Potential benefits include clearer communication of data quality and the identification of achievable targets to benchmark quality improvement initiatives. PMID- 27720559 TI - Humeral head osteotomy in shoulder arthroplasty: a comparison between anterosuperior and inferoanterior resection techniques. AB - BACKGROUND: The best chance that a shoulder arthroplasty will restore motion and muscle balance across the glenohumeral joint is by closely replicating natural articular morphology. Defining the humeral osteotomy plane along clear landmarks at the anatomic neck is critical. We hypothesized that a new osteotomy, based on alternative landmarks on the anatomic neck, would restore 3-dimensional humeral head morphology more reliably than the traditional osteotomy. METHODS: The anatomic neck was digitized in 30 human cadaver shoulders and compared with its 3 dimensional computed tomography reconstruction. Two different osteotomy techniques were virtually performed: the traditional, following the anterosuperior anatomic neck; and a new technique, defined by the inferoanterior anatomic neck. The length-width difference and orientation (retroversion, inclination) of the resection area were compared between the techniques and with native anatomy. RESULTS: Length-width difference of the anterosuperior resection area was higher than in the inferoanterior osteotomy (6 +/- 2 mm vs. 3 +/- 1 mm; P < .001). Retroversion of the anterosuperior resection plane was higher than the native head (50 degrees +/- 12 degrees vs. 37 degrees +/- 11 degrees ; P < .001), whereas retroversion after the inferoanterior osteotomy (32 degrees +/- 12 degrees ) did not differ from native (P = .057). Inclination differed after the anterosuperior osteotomy (129 degrees +/- 5 degrees ) and the inferoanterior osteotomy (127 degrees +/- 4 degrees ) compared with the native head (134 degrees +/- 4 degrees ; P <= .001). CONCLUSION: The inferoanterior referenced osteotomy generated a more circular resection area, matching the native humeral head retroversion more closely than in the anterosuperior technique. This study suggests that in shoulder arthroplasty, the humeral resection level should be referenced at the inferoanterior rather than the anterosuperior anatomic neck. Further studies should investigate the biomechanical effects of this alternative resection plane. PMID- 27720560 TI - Glenoid deformity in the coronal plane correlates with humeral head changes in osteoarthritis: a radiographic analysis. AB - BACKGROUND: A variety of measurements can be used to assess radiographic osteoarthritic changes of the shoulder. This study aimed to analyze the correlation between the radiographic humeral-sided Samilson and Prieto classification system and 3 different radiographic classifications describing the changes of the glenoid in the coronal plane. METHODS: The study material included standardized radiographs of 50 patients with idiopathic osteoarthritis before anatomic shoulder replacement. On the basis of radiographic measurements, the cases were evaluated using the Samilson and Prieto grading system, angle beta, inclination type, and critical shoulder angle by 2 independent observers. RESULTS: Classification measurements showed an excellent agreement between observers. Our results showed that the humeral-sided Samilson and Prieto grading system had a statistically significant good correlation with angle beta (observer 1, r = 0.74; observer 2, r = 0.77; P < .05) and a statistically significant excellent correlation with the inclination type of the glenoid (observer 1, r = 0.86; observer 2, r = 0.8; P < .05). A poor correlation to the critical shoulder angle was observed (r = -0.14, r = 0.03; P > .05). CONCLUSIONS: The grade of humeral-sided osteoarthritis according to Samilson and Prieto correlates with the glenoid-sided osteoarthritic changes of the glenoid in the coronal plane described by the angle beta and by the inclination type of the glenoid. Higher glenoid-sided inclination is associated with higher grade of osteoarthritis in primary shoulder osteoarthritis. PMID- 27720561 TI - Histiocytic proliferations. AB - The study of Histiocytic lesions has been a passion of Pepper Dehner over the years. He has contributed several case series and reviews on various categories of these diseases for over 4 decades, with his earliest articles in the 1970s. He has written on all aspects of the disease including seminal articles on Langerhans cell histiocytosis (LCH) and their prognostic features, his experiences with regressing atypical histiocytosis, his encounters with malignant histiocytosis, and classic articles on juvenile xanthogranuloma. His contributions in the form of chapters in his 2 editions of the unique Pediatric Pathology textbook are no less important than his many articles. His experience with these lesions is highlighted in the 2 editions of the book, and the author and the audience is left wishing for more in a more current version. This article is more of a journey from descriptions and understanding of these various histiocytic syndromes to the current understanding and classifications with molecular inputs and recent advances. This article is dedicated to a master Clinician, Pathologist, and mentor whose contributions to the field of Pediatric Pathology makes him deserve beyond all doubt the title of "Father of Modern Pediatric Pathology." PMID- 27720562 TI - Pediatric renal and genitourinary tract tumors and the contributions of Dr. Louis "Pepper" Dehner therewith. AB - Dr. Louis "Pepper" Dehner is an internationally renowned surgical pathologist, especially in the subspecialty of pediatric pathology. Although his clinical and academic expertise are broad, with over 400 published articles, some of his most intriguing contributions have been in the area of pediatric renal and genitourinary pathology. This review focuses on the entities in these following organ systems where he has focused his efforts: malignant rhabdoid tumor, renal medullary carcinoma, Ewing sarcoma/peripheral neuroectodermal tumor, and the DICER1-related lesions cystic nephroma, embryonal rhabdomyosarcoma of the uterine cervix, and Sertoli-Leydig cell tumor. PMID- 27720563 TI - Contributions of Dr. Louis "Pepper" Dehner to the art of cutaneous pathology, the first pediatric dermatopathologist. AB - Dr. Louis "Pepper" Dehner has been one of the most influential surgical pathologists of the last century. Authoring more than 450 publications, he is the premier modern pediatric pathologist. Perhaps, an area that he is less recognized and in which we would like to describe his contributions, is his role as a creator of the art of pediatric dermatopathology. Dr. Dehner has had at least 50 major publications describing, discovering, and orienting the discipline in the fields of fibrohistiocytic disorders of childhood, vascular tumors, and histiocytosis among many others. Dr. Dehner has clearly manifested that while many similarities between adult and pediatric surgical pathology exist, "children get different diseases." It is because of his mindful analysis and translation of the clinico-pathologic and biologic correlative between specific entities and advances in the field he has made that we are honored to describe some of his contributions to this particular area. PMID- 27720564 TI - Correlation between lymph node count and survival and a reappraisal of lymph node ratio as a predictor of survival in gastric cancer: A multi-institutional cohort study. AB - PURPOSE: The purpose of this study is to evaluate the correlation between lymph node count (LNC) and survival and to evaluate whether lymph node ratio (LNR) which is related to LNC is a better predictor of survival for gastric cancer than the N category of UICC/AJCC through a multi-institutional cohort study. METHODS: The study cohort included 3284 patients from eight institutions. Lower and upper quartiles of LNC were used for comparisons. The cut-off values (0, 0.06, 0.27, and 0.49) for the LNR categories were based on Classification and Regression Trees techniques. Akaike information criteria (AIC) for Cox regression models was used to evaluate goodness of fit between competing predictor variables (LNR vs. N category). RESULTS: The 5-year disease-specific survival (DSS) rates of lower and upper quartiles of LNC were 82.2% and 84.8%. In the subgroup analysis of pN category, the upper quartile of LNC showed better survival than the lower quartile in pN2, pN3a, and pN3b subgroups. Regarding LNR, 5-year DSS of LNR 0, 0 0.06, 0.06-0.27, 0.27-0.49, and >0.49 was 95.3%, 88.7%, 70.6%, 42.7%, and 17.2% respectively. Multivariate analysis showed that pT, pN, LNR, residual tumor status, distant metastasis, and tumor differentiation significantly affected survival. The analysis also confirmed superiority of LNR compared with N category in the AIC analysis. CONCLUSION: Higher LNC correlated with better survival in patients with pN2, pN3a, and pN3b gastric cancer. Our data indicate that LNR is a better predictor of survival than N category of UICC/AJCC.

PMID- 27720566 TI - Analyses of pressure ulcer incidence in inpatient setting in a Portuguese hospital. AB - AIM: To gain more insight into the magnitude of the problem of pressure ulcer incidence in general wards of a Portuguese hospital. MATERIAL AND METHODS: Retrospective cohort analysis of electronic health record database from 7132 adult patients admitted to medical and surgical wards of Aveiro Hospital during 2012. The development of (at least) one pressure ulcer during the length of stay was associated with age, gender, type of admission, specialty units, first Braden Scale score, length of stay, patient discharge outcome and ICD-9 diagnosis. RESULTS: An incidence of 3.4% participants with pressure ulcer category I-IV in inpatient setting during 2012. During the length of stay, 320 new pressure ulcers were developed, most of them category/stage II. The sacrum/coccyx and the trochanters were the most problematic areas. CONCLUSIONS: The major risk factor for the development of a new pressure ulcer during the length of stay was the presence of (at least) one pressure ulcer at the first skin assessment. The length of stay itself, age and lower Braden Scale scores of our participants also played an important role in the odds of developing a pressure ulcer. Infectious diseases, traumatism and fractures and respiratory diseases were the ICD-9 diagnoses with higher frequency of participants that developed (at least) one pressure ulcer during the length of stay. It's important to standardize procedures and documentation in all care settings. The documentation of nursing interventions is vital to evaluate the impact of evidence-based nursing. PMID- 27720567 TI - Bacterial meningitis without pleocytosis. PMID- 27720568 TI - The impact of push-dose phenylephrine use on subsequent preload expansion in the ED setting. AB - BACKGROUND: The utilization of bolus-dose phenylephrine (PHE) has transitioned to the emergency department (ED) for the treatment of acutely hypotensive patients, despite a paucity of literature in this setting. METHODS: This was a single center retrospective chart review of the utilization of bolus-dosed PHE for acute hypotension in the ED at an academic non-forprofit hospital. The primary objective of this study is to report the frequency of patients that were initiated on a continuous vasopressor infusion (CVI) within 30 minutes after the first administration of bolus-dose PHE. Secondary objectives included an observational description of the impact of early preload expansion (fluids) on the initiation of CVIs in the setting of bolus-dose PHE in the ED. RESULTS: Seventy-three patients met inclusion criteria for analysis. The primary outcome, 46.5% (n = 34) of patients were initiated on a CVI within 30 minutes following bolus-dose PHE. Initial preload expansion (30 mL/kg of IV fluids) was found to be significantly disproportionate with 34.2% appropriately fluid challenged vs 65.8% (P = .0048). In addition, a significant decrease in the number of PHE bolus doses were required [1.5 vs 2.3 (P = .01)] in the adequately IVF challenged group. For secondary endpoints, PHE was most commonly indicated for peri-intubation hypotension (n = 52, 71.2%). Significant adverse events were documented for 15 (20.5%) patients, with bradycardia (n = 7; 9.6%) as the most common adverse event. CONCLUSIONS: Initial preload IVF expansion was found to be significantly disproportionate, and appears to be associated with an increase number of phenylephrine bolus doses in our study population.

AB - PURPOSE: To review the outcome of epilepsy after stopping antiepileptic drugs in remission. RESULTS: Stopping antiepileptic drugs (AEDs) in remission is routinely done in many patients. Although the consequences of an unexpected relapse seizure in the 2 years after stopping AEDs may cause anguish and social issues, the impact on the long term seizure outlook of the epilepsy is minimal, if any. Discontinuation of drug treatment does not seem to affect the long-term prognosis but exposes patients who were seizure-free for years to a transient two-fold risk of seizures for the first 2 years after stopping AEDs. In addition, 20% of patients who were seizure-free for years, do not become seizure-free immediately after restarting AED treatment after relapse. The list of potential pitfalls is long. Patients with juvenile myoclonic epilepsy, those with prior withdrawal attempts and late remission have a higher risk of relapse. CONCLUSION: Stopping AEDs in remission does not affect the long-term patterns of epilepsy and some patients report a better general health in a life without AEDs. High-risk patients should not be generally encouraged to stop their AEDs in remission. We need new drugs that combine anti-seizure and antiepileptogenic effects to prevent seizure relapse and flare up of epilepsy after stopping AEDs in remission.

AB - PURPOSE: To study the ability of a human operator to manually correct for errors in the needle insertion path without partial withdrawal of the needle by means of an active, tip-articulated steerable needle. MATERIALS AND METHODS: The needle is composed of a 1.32-mm outer-diameter cannula, with a flexure joint near the tip, and a retractable stylet. The bending stiffness of the needle resembles that of a 20-gauge hypodermic needle. The needle functionality was evaluated in manual insertions by steering to predefined targets and a lateral displacement of 20 mm from the straight insertion line. Steering tasks were conducted in 5 directions and 2 tissue simulants under image guidance from a camera. The repeatability in instrument actuations was assessed during 100 mm deep automated insertions with a linear motor. In addition to tip position, tip angles were tracked during the insertions. RESULTS: The targeting error (mean absolute error +/- standard deviation) during manual steering to 5 different targets in stiff tissue was 0.5 mm +/- 1.1. This variability in manual tip placement (1.1 mm) was less than the variability among automated insertions (1.4 mm) in the same tissue type. An increased tissue stiffness resulted in an increased lateral tip displacement. The tip angle was directly controlled by the user interface, and remained unaffected by the tissue stiffness. CONCLUSIONS: This study demonstrates the ability to manually steer needles to predefined target locations under image guidance. PMID- 27720574 TI - Optimizing radiation exposure for CT localizer radiographs. AB - INTRODUCTION: The trend towards submillisievert CT scans leads to a higher dose fraction of localizer radiographs in CT examinations. The already existing technical capabilities make dose optimization of localizer radiographs worthwhile. Modern CT scanners apply automatic exposure control (AEC) based on attenuation data in such a localizer. Therefore not only this aspect but also the detectability of anatomical landmarks in the localizer for the desired CT scan range adjustment needs to be considered. MATERIALS AND METHODS: The effective dose of a head, chest, and abdomen-pelvis localizer radiograph with standard factory settings and user-optimized settings was determined using Monte Carlo simulations. CT examinations of an anthropomorphic phantom were performed using multiple sets of acquisition parameters for the localizer radiograph and the AEC for the subsequent helical CT scan. Anatomical landmarks were defined to assess the image quality of the localizer. CTDIvol and effective mAs per slice of the helical CT scan were recorded to examine the impact of localizer settings on a helical CT scan. RESULTS: The dose of the localizer radiograph could be decreased by more than 90% while the image quality remained sufficient when selecting the lowest available settings (80kVp, 20mA, pa tube position). The tube position during localizer acquisition had a greater impact on the AEC than the reduction of tube voltage and tube current. Except for the use of a pa tube position, all changes of acquisition parameters for the localizer resulted in a decreased total radiation exposure. CONCLUSION: A dose reduction of CT localizer radiograph is necessary and possible. In the examined CT system there was no negative impact on the modulated helical CT scan when the lowest tube voltage and tube current were used for the localizer. PMID- 27720575 TI - Transoral Stensen's Duct Approach: A 22-case retrospective study. AB - INTRODUCTION: Parotid gland duct lithiasis is preferentially managed using minimally-invasive techniques such as sialendoscopy and lithotripsy. However, these 2 techniques cannot remedy all obstructions and other techniques such as the Transoral Stensen's Duct Approach (TSDA) may sometimes be helpful. MATERIAL AND METHODS: A retrospective study of patients treated with TSDA was conducted to evaluate this procedure between 2006 and 2013. Criteria for inclusion were: failures for lithiases (22 patients and 28 lithiases) treated with sialendoscopy and/or lithotripsy for parotid gland duct obstruction. Mean follow-up was 47.4 months. Pain intensity, swelling and occurrence of infectious episodes were evaluated immediately and after middle-term and long-term follow-up (up to 36 months). RESULTS: The best results were obtained for anterior lithiasis, with an 87.5% immediate success rate. Morbidity was low with 2 transient facial nerve upper buccal branch palsies and 2 post-operative stenoses. DISCUSSION: TSDA is an easy-to-perform and safe technique that can be recommended in cases of sialendoscopy or lithotripsy failure for anterior-third parotid duct lithiasis. Even if this technique has shown limitations for more posterior lithiases, or other causes of obstruction (stenosis, megaduct), it requires no specific material and may be useful. It may avoid an external combined approach or a parotidectomy. PMID- 27720576 TI - Concordance of immune checkpoints within tumor immune contexture and their prognostic significance in gastric cancer. AB - Checkpoint blockade therapy has emerged as a novel approach for cancer immunotherapy in several malignancies. However, patient prognosis and disease progression relevant to immune checkpoints in gastric tumor microenvironment are not defined. This study aims to investigate the expression and prognostic significance of immune checkpoints within gastric cancer. In the study, a cohort of 398 cancer tissues from stage I to IV gastric cancer patients were assessed for programmed cell death 1 ligand 1 (PD-L1) expression and tumor-infiltrating lymphocyte (TIL) infiltration using immunohistochemistry to ascertain their survival correlation. The data revealed that higher TIL density correlated with less risk of disease progression, and exhibited survival benefits in gastric cancer patients, and PD-L1 positivity showed a significant association with the presence of high TIL infiltration. Furthermore, real-time quantitative polymerase chain reaction was performed to detect expression of multiple immune checkpoints with the relation to clinical outcome in 139 samples randomly selected from the same cohort, and higher messenger RNA levels of most immune checkpoints were associated with favorable outcome, while consistently showing a positive correlation with interferon gamma levels. In situ hybridization was used to determine the localization of Epstein-Barr virus (EBV) in 97 specimens, and showed EBV-positive gastric cancer samples correlated with PD-L1 expression and increased TIL density. These results suggest that induction of immune checkpoint within gastric cancer patients reflects a high immune infiltration density, especially in those with EBV-associated gastric cancer, which may direct patient selection for checkpoint blockade therapy. PMID- 27720577 TI - Early use of chemotherapy in metastatic prostate cancer. AB - Since 2010, five new antineoplastic therapies have been FDA approved for the treatment of metastatic prostate cancer. With additional treatment options, questions arose about the optimal sequence of these agents. Until recently, chemotherapy has been deferred until later in the disease course in favor of next generation androgen deprivation therapy. Prior to the development of abiraterone acetate and enzalutamide, clinical trials were opened investigating the combination of chemotherapy with androgen deprivation therapy in patients with metastatic hormone-sensitive disease. With the development of new oral therapies used to treat castration-resistant disease, these trials were largely forgotten or felt to be obsolete. Recently, two trials have been reported showing an overall survival benefit of the early use of chemotherapy in patients with hormone-naive prostate cancer, changing the treatment paradigm for metastatic disease. Here we review the history of chemotherapy in treating prostate cancer and the emerging evidence favoring its use as first-line therapy against metastatic hormone-sensitive disease. PMID- 27720579 TI - Site-specific diel mercury emission fluxes in landfill: Combined effects of vegetation and meteorological factors. AB - Mercury emission fluxes (MEFs) under different surface coverage conditions in a landfill were investigated in this study. The results show similar diel patterns of Hg emission flux under different coverage conditions, with peak fluxes occurring at midday and decreasing during night. We examined the effects of environmental factors on MEFs, such as the physiological characteristics of vegetation and meteorological conditions. The results suggest that growth of vegetation in the daytime facilitates the release of Hg in the anaerobic unit, while in the semi-aerobic unit, where vegetation had been removed, the higher mercury content of the cover soil prompted the photo-reduction pathway to become the main path of mercury release and increased MEFs. MEFs are positively correlated with solar radiation and air temperature, but negatively correlated with relative humidity. The correlation coefficients for MEFs with different environmental parameters indicate that in the anaerobic unit, solar radiation was the main influence on MEFs in September, while air temperature became the main determining factor in December. These observations suggest that the effects of meteorological conditions on the mercury release mechanism varies depending on the vegetation and soil pathways. PMID- 27720578 TI - Panic attacks and panic disorder in the American Indian community. AB - Panic disorder is a common mental health condition, but little is known about panic disorder in non-Caucasian populations. The purpose of this study is to describe the epidemiology, clinical features, and comorbidities of panic attacks and panic disorder in two large American Indian (AI) tribes (N=3084). A culturally-adapted version of the Composite International Diagnostic Interview assessed panic attacks, panic disorder, and various psychiatric comorbidities. After adjusting for age, gender, and tribe, linear and logistic regression analyses were conducted to compare AIs with panic disorder to those with panic attacks only on clinical characteristics and panic symptoms. Approximately 8.5% (N=234) of American Indians reported a lifetime history of panic attacks. Among individuals with panic attacks, comorbid posttraumatic stress disorder was higher in females (p=0.03) and comorbid alcohol-related disorders were higher in males (p<=0.001). The prevalence and clinical features of panic attacks and panic disorder in American Indians were similar to epidemiologic studies with majority populations. However, in contrast to earlier research, panic symptoms were similar in both males and females, and different patterns of comorbidity emerged. Future research should examine the availability and accessibility of evidence based panic treatments for this traditionally underserved population. PMID- 27720580 TI - Modelling of composting process of different organic waste at pilot scale: Biodegradability and odor emissions. AB - The composting process of six different compostable substrates and one of these with the addition of bacterial inoculums carried out in a dynamic respirometer was evaluated. Despite the heterogeneity of the compostable substrates, cumulative oxygen demand (OD, mgO2kgVS) was fitted adequately to an exponential regression growing until reaching a maximum in all cases. According to the kinetic constant of the reaction (K) values obtained, the wastes that degraded more slowly were those containing lignocellulosic material (green wastes) or less biodegradable wastes (sewage sludge). The odor emissions generated during the composting processes were also fitted in all cases to a Gaussian regression with R2 values within the range 0.8-0.9. The model was validated representing real odor concentration near the maximum value against predicted odor concentration of each substrate, (R2=0.9314; 95% prediction interval). The variables of maximum odor concentration (ouE/m3) and the time (h) at which the maximum was reached were also evaluated statistically using ANOVA and a post-hoc Tukey test taking the substrate as a factor, which allowed homogeneous groups to be obtained according to one or both of these variables. The maximum oxygen consumption rate or organic matter degradation during composting was directly related to the maximum odor emission generation rate (R2=0.9024, 95% confidence interval) when only the organic wastes with a low content in lignocellulosic materials and no inoculated waste (HRIO) were considered. Finally, the composting of OFMSW would produce a higher odor impact than the other substrates if this process was carried out without odor control or open systems.

PMID- 27720583 TI - Ovarian Cancer: An Evidence-Based, Easy-to-Use Prediction Rule to Optimize the Use of Follow-up Chest CT. AB - PURPOSE: To create and validate an evidence-based prediction rule to optimize use of follow-up chest CT for ovarian cancer. METHODS: In this Institutional Review Board-approved retrospective study performed at two academic medical centers, electronic medical records from January through December 2013 at center 1 (USA) and January 2012 through December 2013 at center 2 (South Korea) were searched to identify consecutive chest CTs performed within 5 years of initial cytoreductive surgery in patients with pathologically proven ovarian cancer. Three separate study cohorts were created: cohort 1, 316 CTs (in 150 patients) with high-grade serous ovarian cancer (HGSC) from center 1; cohort 2, 374 CTs (81 patients) with HGSC from center 2; and cohort 3, 87 CTs (56 patients) with non-HGSC histologies from center 1. A radiologist blinded to outcome of CT, using a prediction rule that utilized previously available information, categorized each CT into "high risk" (stage 4 at presentation and/or preexisting abdominal disease [disease below diaphragmatic dome, visualized on abdominal CT]) or "low-risk" (neither of above). A blinded radiologist then reviewed chest CTs in random order to record thoracic metastases above the diaphragmatic dome, and outcome was compared with prediction rule risk category. RESULTS: Among the three cohorts and in the total population, the prediction rule identified 94 of 316 (30%), 170 of 374 (45%), 53 of 87 (61%), and 317 of 777 (41%) CTs as "low-risk," respectively. The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were as follows: cohort 1: 95%, 35%, 24%, 97%, 1.46, 0.14; cohort 2: 88%, 53%, 29%, 95%, 1.87, 0.22; cohort 3: 88%, 66%, 21%, 98%, 2.59, 0.18; total population: 91%, 47%, 26%, 96%, 1.72, 0.19. False-negative rate in the three cohorts and in total population was 3 of 94 (3%), 8 of 170 (5%), 1 of 53 (2%), and 12 of 317 (4%); however, in each of these cases there was concurrent new abdominal disease. CONCLUSIONS: The easy to-use prediction rule helps avoid unnecessary chest CTs in patients with ovarian cancer with high sensitivity and negative predictive value, and with minimal risk of missing thoracoabdominal metastases. PMID- 27720584 TI - Growing up in wartime: Evidence from the era of two world wars. AB - We document the association between war-related shocks in childhood and adult outcomes for Europeans born during the first half of the twentieth century. Using a variety of data, at both the macro- and the micro-level, we address the following questions: What are the patterns of mortality among Europeans born during this period? Do war-related shocks in childhood and adolescence help predict adult health, human capital and wellbeing of the survivors? Are there differences by sex, socio-economic status in childhood, and age when the shocks occurred? At the macro-level, we show that the secular trend towards lower mortality was interrupted by dramatic increases in mortality during World War I, the Spanish Flu, the Spanish Civil War, and World War II, and we quantify the size of these mortality shocks. Different patterns characterize these high mortality episodes, with substantial variation by country, sex and age group. At the micro-level, we show that war-related hardship in childhood or adolescence, in particular exposure to war events and experience of hunger, is associated with worse physical and mental health, education, cognitive ability and subjective wellbeing at older ages. The strength of the association differs by sex and type of hardship, with war exposure being more important for females and experience of hunger for males. We also show that hardships matter more if experienced in childhood, and have stronger consequences if they last longer. PMID- 27720585 TI - Updated feasibility and reproducibility results of multi-institutional study of noninvasive breast tumor bed boost. AB - PURPOSE: To report updated feasibility and reproducibility results for high-dose rate noninvasive breast brachytherapy (NIBB) for tumor bed boost with whole breast radiation therapy (WBRT) in the setting of expanded patient and treatment facility number. METHODS AND MATERIALS: Fifteen independent community-based and academic centers reported 518 early-stage breast cancer patients from July 2007 to February 2015 on a privacy-encrypted online data registry. All patients' treatment included lumpectomy followed by combination of WBRT and NIBB. NIBB was completed with commercially available (AccuBoost, Billerica, MA) mammography based system using high-dose-rate 192Ir emissions along orthogonal axes. Harvard scale was used to grade cosmesis. RESULTS: Total patient cohort had median followup of 12 months (1-75 months) with subset of 268 having available cosmesis. Greater than 2- and 3-year followup was 29% and 14%, respectively. Entire cohort had 97.4% excellent/good (E/G) breast cosmesis and freedom from recurrence of 97.6% at the final followup. WBRT timing with respect to NIBB delivery demonstrated no statistically significant difference in E/G cosmesis. Achieved E/G cosmesis rate was also not statistically significant (chi2p-value = 0.86) between academic and community institutions with 97.8% vs. 96.6%. CONCLUSIONS: NIBB represents an alternative method for delivery of breast tumor cavity boost that has shown feasibility in a diverse group of both academic and community based practices with reproducible early cosmesis and tumor control results. Recommendations are updated noting ideal timing of boost delivery likely to be before or early during WBRT given equal cosmesis and less documented treatment discomfort. PMID- 27720587 TI - Composition of growth factors and cytokines in lysates obtained from fresh versus stored pathogen-inactivated platelet units. AB - BACKGROUND: Platelet lysate is a readily available source of growth factors, and other mediators, which has been used in a variety of clinical applications. However, the product remains poorly standardized and the present investigation evaluates the composition of platelet lysate obtained from either fresh or stored pathogen-inactivated platelet units. MATERIALS AND METHODS: Platelet pooled units (n = 10) were obtained from healthy blood donors and tested according to standard procedures. All units were pathogen inactivated using amotosalen hydrochloride and UVA exposure. Platelet lysate was subsequently produced at two separate time points, either from fresh platelet units or after 5 days of storage, by repeated freeze-thaw cycles. The following mediators were determined at each time-point: EGF, FGF-2, VEGF, IGF-1, PDGF-AB/BB, BMP-2, PF4, TGF-beta isoform 1, IL-1beta, IL 2, IL-6, IL-10, IL-12p70, 1L-17A, TNF-alpha, and IFN-gamma. RESULTS: The concentration of growth factors and cytokines was affected by time in storage. Notably, TGF-beta, PDGF-AB/BB, and PF4 showed an increase of 27.2% (p < 0.0001), 29.5% (p = 0.04) and 8.2% (p = 0.0004), respectively. A decrease was seen in the levels of IGF-1 and FGF-2 with 22% (p = 0.041) and 11% (p = 0.01), respectively. Cytokines were present only in very low concentrations and all other growth factors remained stable with time in storage. CONCLUSION: The composition of mediators in platelet lysate obtained from pathogen-inactivated platelet units differs when produced from fresh and stored platelet units, respectively. This underscores the need for further standardization and optimization of this important product, which potentially may influence the clinical effects. PMID- 27720586 TI - Endoplasmic Reticulum Proteostasis Influences the Oligomeric State of an Amyloidogenic Protein Secreted from Mammalian Cells. AB - Transthyretin (TTR) is a tetrameric serum protein associated with multiple systemic amyloid diseases. In these disorders, TTR aggregates in extracellular environments through a mechanism involving rate-limiting dissociation of the tetramer to monomers, which then misfold and aggregate into soluble oligomers and amyloid fibrils that induce toxicity in distal tissues. Using an assay established herein, we show that highly destabilized, aggregation-prone TTR variants are secreted as both native tetramers and non-native conformations that accumulate as high-molecular-weight oligomers. Pharmacologic chaperones that promote endoplasmic reticulum (ER) proteostasis of destabilized TTR variants increase their fraction secreted as a tetramer and reduce extracellular aggregate populations. In contrast, disrupting ER proteostasis reduces the fraction of destabilized TTR secreted as a tetramer and increases extracellular aggregates. These results identify ER proteostasis as a factor that can affect conformational integrity and thus toxic aggregation of secreted amyloidogenic proteins associated with the pathology of protein aggregation diseases. PMID- 27720588 TI - A Highly Conserved Yet Flexible Linker Is Part of a Polymorphic Protein-Binding Domain in Myosin-Binding Protein C. AB - The nuclear magnetic resonance (NMR) structure of the tri-helix bundle (THB) of the m-domain plus C2 (DeltamC2) of myosin-binding protein C (MyBP-C) has revealed a highly flexible seven-residue linker between the structured THB and C2. Bioinformatics shows significant patterns of conservation across the THB-linker sequence, with the linker containing a strictly conserved serine in all MyBP-C isoforms. Clinically linked mutations further support the functional significance of the THB-linker region. NMR, small-angle X-ray scattering, and binding studies show the THB-linker plus the first ten residues of C2 undergo dramatic changes when DeltamC2 binds Ca2+-calmodulin, with the linker and C2 N-terminal residues contributing significantly to the affinity. Modeling of all available experimental data indicates that the THB tertiary structure must be disrupted to form the complex. These results are discussed in the context of the THB-linker and the N-terminal residues of C2 forming a polymorphic binding domain that could accommodate multiple binding partners in the dynamic sarcomere. PMID- 27720590 TI - Sono-crystallization kinetics of K2SO4: Estimation of nucleation, growth, breakage and agglomeration kinetics. AB - Application of ultrasound in crystallization has showed improved process characteristics. Although several attempts have been made in the past to study the sono-crystallization kinetics, only nucleation and crystal growth were considered, neglecting breakage and agglomeration of crystals. In this study, an attempt is made for the estimation of the kinetic parameters of all the phenomena occurring simultaneously during sono-crystallization. For this, both conventional and ultrasonic crystallization of K2SO4-water system has been reported. Sono crystallization experiments were carried out using ultrasonic horn operating at 20 kHz frequency. Reduction in the induction time, reduction in metastable zone width (MSZW), narrowing of crystal size distribution (CSD) were the key observations of sono-crystallization experiments. Population balance equations (PBE) were used to model the crystallization system and the various kinetic parameters have been estimated. The kinetic parameters obtained for conventional crystallization and sonocrystallization were compared. The estimated parameters suggest an increase in nucleation and breakage rate during sono-crystallization. Growth rates were observed to be of the same order of magnitude for both conventional and sonocrystallization. While agglomeration during sono crystallization was found to be negligible. PMID- 27720589 TI - Crystal Structure of the Neuropilin-1 MAM Domain: Completing the Neuropilin-1 Ectodomain Picture. AB - Neuropilins (NRPs) are single-pass transmembrane receptors involved in several signaling pathways that regulate key physiological processes such as vascular morphogenesis and axon guidance. The MAM domain of NRP, which has previously been implicated in receptor multimerization, was the only portion of the ectopic domain of the NRPs for which the structure, until now, has been elusive. Using site-directed mutagenesis in the linker region preceding the MAM domain we generated a protein construct amenable to crystallization. Here we present the crystal structure of the MAM domain of human NRP1 at 2.24 A resolution. The protein exhibits a jellyroll topology, with Ca2+ ions bound at the inter-strand space enhancing the thermostability of the domain. We show that the MAM domain of NRP1 is monomeric in solution and insufficient to drive receptor dimerization, which leads us to propose a different role for this domain in the context of NRP membrane assembly and signaling. PMID- 27720592 TI - Sonochemical synthesis and structural determination of novel the nano-card house Cu(II) metal-organic coordination system. AB - A sonochemical method by using various time and concentrations of initial reagents and power of irradiation, was used to synthesize nano-card house of a new copper(II) metal-organic coordination system, {[Cu2(p-2yeinh)2Cl2].(H2O)}n (1), where p-2yeinh=pyridin-2-yl ethylidene-isonicotinohydrazide. The compound was characterized by scanning electron microscopy (SEM), elemental analysis, IR spectroscopy, X-ray powder diffraction (XPRD), and single crystal X-ray analysis. The X-ray structure revealed that the Cu(II) atom is coordinated by one oxygen and three nitrogen atoms from two p-2yeinh ligands and one chloride anion with a CuN3OCl donor set with square pyramid geometry. This arrangement produces a large quadric nuclear square ring composed of four square pyramid Cu(II) moieties linked together by two p-2yeinh units (M4L4). The adjacent frameworks connected by strong hydrogen bonding interactions of methanol molecules that interact together and with the rings and pi-pi interactions of adjacent aromatic rings of p-2yeinh and other weak interactions. Consequently, the labile interactions also allow the discrete structure to form a 3D metal-organic coordination network. CuO nanoparticles were obtained by thermolysis of 1 at 180 degrees C with oleic acid as a surfactant. The average diameter of the nanoparticles was estimated by XPRD to be 38nm. The morphology and size of the prepared CuO nanoparticles were further studied using SEM. PMID- 27720591 TI - Ultrasound-assisted CO2 flooding to improve oil recovery. AB - CO2 flooding process as a common enhanced oil recovery method may suffer from interface instability due to fingering and gravity override, therefore, in this study a method to improve the performance of CO2 flooding through an integrated ultraosund-CO2 flooding process is presented. Ultrasonic waves can deliver energy from a generator to oil and affect its properties such as internal energy and viscosity. Thus, a series of CO2 flooding experiments in the presence of ultrasonic waves were performed for controlled and uncontrolled temperature conditions. Results indicate that oil recovery was improved by using ultrasound assisted CO2 flooding compared to conventional CO2 flooding. However, the changes were more pronounced for uncontrolled temperature conditions of ultrasound assisted CO2 flooding. It was found that ultrasonic waves create a more stable interface between displacing and displaced fluids that could be due to the reductions in viscosity, capillary pressure and interfacial tension. In addition, higher CO2 injection rates, increases the recovery factor in all the experiments which highlights the importance of injection rate as another factor on reduction of the fingering effects and improvement of the sweep efficiency. PMID- 27720593 TI - Sonocatalytic degradation of ciprofloxacin using synthesized TiO2 nanoparticles on montmorillonite. AB - TiO2/Montmorillonite (TiO2/MMT) nanocomposite as sonocatalyst was produced by immobilizing synthesized TiO2 on the surface of montmorillonite. The characteristics of produced nanocomposite were investigated using XRD, XRF, FTIR, TEM, SEM, EDX, UV-vis DRS and nitrogen adsorption-desorption analyses. The synthesized TiO2 and TiO2/MMT samples were applied as catalysts for sonocatalytic degradation of ciprofloxacin (CIP). The performance of the TiO2/MMT was greater than pure TiO2 sample in treatment of CIP solution. The degradation efficiency of the CIP by sonocatalytic process was affected by solution pH, catalyst dosage, initial CIP concentrations and ultrasonic power. Degradation efficiency of 65.01% was obtained at the pH of 6, catalyst dosage of 0.2gL-1, initial CIP concentration of 10mgL-1 and ultrasonic power of 650WL-1. It was observed that the presence of inorganic and organic scavengers suppressed the performance of sonocatalytic process. The stability of the nanocomposite was studied in several successive experiments, and the degradation efficiency declined only 61.48% after 4 repeated experiments. The main degradation by-products were recognized by GC-MS method to propose the possible sonocatalytic mechanism for the degradation of CIP. PMID- 27720594 TI - Photoelectrocatalytic degradation of oxalic acid using WO3 and stratified WO3/TiO2 photocatalysts under sunlight illumination. AB - The WO3 and stratified WO3/TiO2 thin films are successfully prepared by the spray pyrolysis method. The structural, morphological, compositional and photoelectrocatalytic properties of WO3 and stratified WO3/TiO2 thin films are studied. XRD analysis confirms that films are polycrystalline with monoclinic and tetragonal crystal structures for WO3 and TiO2 respectively. The SEM images clearly show 3D sheeted porous structure of the as-prepared TiO2 forms on WO3 in stratified WO3/TiO2 samples. The synthesized photoelectrodes was used as catalyst for photoelectrocatalytic degradation of oxalic acid in aqueous medium. The rate constant (k) was evaluated as a function of the initial concentration of species. A significant decrease in concentrations of organic species was observed from COD analysis. The photoelectrocatalytic degradation effect is relatively higher in the case of the stratified WO3/TiO2 than WO3 thin film photoelectrode in the degradation of oxalic acid and 83% removal efficiency of oxalic acid is obtained after 180min. Based on the obtained experimental data, the possible photoelectrocatalytic reaction mechanism was proposed. The photoelectrocatalytic experimental results indicate that stratified WO3/TiO2 photoelectrode is the promising material for removing of water pollutants. PMID- 27720595 TI - Drug therapy problems and medication discrepancies during care transitions in super-utilizers. AB - OBJECTIVES: First, to investigate the prevalence and types of drug therapy problems and medication discrepancies among super-utilizers, and associated patient characteristics. Second, to examine the outcomes of pharmacist recommendations and estimated cost avoidance through care transitions support focused on medication management. DESIGN: Retrospective analysis of the pharmacist-led interventions as part of the SafeMed Program. SETTING: A large nonprofit health care system serving the major medically underserved areas in Memphis, Tennessee. PARTICIPANTS: Three hundred seventy-four super-utilizing SafeMed participants with multiple chronic conditions and polypharmacy. INTERVENTION: Comprehensive medication review, medication therapy management, enhanced discharge planning, home visits, telephone follow-up, postdischarge medication reconciliation, and care coordination with physicians. MAIN OUTCOME MEASURES: Types of drug therapy problems, outcomes of pharmacist recommendations, estimated cost avoided, medication discrepancies, and self-reported medication adherence. RESULTS: Prevalence of drug therapy problems and postdischarge medication discrepancies was 80.7% and 75.4%, respectively. The most frequently occurring drug therapy problems were enrollee not receiving needed medications (33.4%), underuse of medications (16.9%), and insufficient dose or duration (11.2%). Overall 50.8% of the pharmacist recommendations were accepted by physicians and patients, resulting in an estimated cost avoidance of $293.30 per drug therapy problem identified. Multivariate analysis indicated that participants with a higher number of comorbidities were more likely to have medication discrepancies (odds ratio 1.23 [95% CI 1.05-1.44]). Additional contributors to postdischarge medication discrepancies were difficulty picking up and paying for medications and not being given necessary prescriptions before discharge. CONCLUSION: Drug therapy problems and medication discrepancies are common in super-utilizers with multiple chronic conditions and polypharmacy during transitions of care, and greater levels of comorbidity magnify risk. Pharmacist-led interventions in the SafeMed Program have demonstrated success in resolving enrollees' medication-related issues, resulting in substantial estimated cost savings. Preliminary evidence suggests that the SafeMed model's focus on medication management has great potential to improve outcomes while reducing costs for vulnerable super-utilizing populations nationwide. PMID- 27720596 TI - Enhanced bio-catalytic performance and dye degradation potential of chitosan encapsulated horseradish peroxidase in a packed bed reactor system. AB - In this study, horseradish peroxidase (HRP) was immobilized onto chitosan beads by entrapment method and employed for the degradation of textile dyes. Stable and firm quality chitosan beads developed with 2.5% chitosan concentration exhibited maximum immobilization yield (~92.54+/-2.53%). The pH optimum of chitosan immobilized HRP (CTS-HRP) was marginally displaced towards alkaline region (pH7.5) than that of F-HRP which displayed its optimum activity at pH7.0. The free HRP (F-HRP) and CTS-HRP enzyme presented their maximum catalytic activities at 30 degrees C and 70 degrees C, respectively. Relative activities of F-HRP and CTS-HRP were decreased following pre-incubation above 30 degrees C and 50 degrees C, respectively and after 120min at 70 degrees C, the F-HRP, and CTS-HRP retained 19.3+/-1.3 and 48.3+/-2.4% activities, accordingly. The CTS-HRP exhibited remarkably better resistance towards heavy metal induced activity inhibition. The effect of potential inhibitors on the activity of F-HRP and CTS-HRP was investigated and found that CTS-HRP was significantly less vulnerable to the denaturation caused by urea, ethylenediaminetetraacetic acid (EDTA), cysteine, 1, 4-dithiothreitol and Triton X-100. Moreover, the CTS-assisted entrapped-HRP was also employed for the decolorization of four different textile dyes i.e. Remazol Brilliant Blue R (RBBR), Reactive Black 5 (RB5), Congo Red (CR) and Crystal Violet (CV). The CTS-HRP showed considerable decolorization efficacy in six consecutive batch operations. Results suggest that CTS-HRP is an attractive choice for use as industrial biocatalyst in larger scale bioremediation of textile dyes and effluents. PMID- 27720597 TI - Global warming increases the interspecific competitiveness of the invasive plant alligator weed, Alternanthera philoxeroides. AB - Global warming could accelerate the spread of invasive species to higher latitudes and intensify their effects on native species. Here, we report results of two years of field surveys along a latitudinal gradient (21 degrees N to 31 degrees N) in southern China, to determine the species structure of the invasive plant Alternanthera philoxeroides community. We also performed a replacement series experiment (mono and mixed) to evaluate the effects of elevated temperature on the competitiveness of A. philoxeroides with the native co occurring species Digitaria sanguinalis. In the field survey, we found that the dominance of A. philoxeroides increased with increasing of latitude gradient while cover of D. sanguinalis decreased. In monospecific plantings, artificial warming reduced the length of D. sanguinalis roots. In mixed plantings, warming reduced both A. philoxeroides abundance and D. sanguinalis stem length when A. philoxeroides was more prevalent in the planting. Warming also significantly reduced D. sanguinalis biomass, but increased that of A. philoxeroides. In addition, elevated temperatures significantly reduced the relative yield (RY) of D. sanguinalis, particularly when A. philoxeroides was planted in higher proportion in the plot. These results suggest that the invasiveness of A. philoxeroides increased with increasing latitude, and that warming may increase the effectiveness of its interspecific competition with D. sanguinalis. Hence, under global warming conditions, the harm to native species from A. philoxeroides would increase at higher latitudes. Our findings are critical for predicting the invasiveness of alien species under climate change. PMID- 27720598 TI - Giant reed growth and effects on soil biological fertility in assisted phytoremediation of an industrial polluted soil. AB - Phytoremediation is a cost-effective "green technology" that uses plants to improve the soil properties of polluted sites, preventing the dispersion of pollutants and reducing the mobility of potentially toxic elements (PTEs) through their adsorption and accumulation by roots or precipitation within the root zone. Being highly tolerant to pollutants and other abiotic stresses, giant reed (Arundo donax L.) is a suitable biomass crop for phytoremediation of contaminated soils. We report the results of a two-year open-air lysimeter study aimed at assessing the adaptability of giant reed to grow on industrial substrates polluted by Pb and Zn and at testing commercial humic acids from leonardite as improvers of plant performance. We evaluated giant reed potential for: 1) biomass production for energy or biomaterial recovery; 2) PTE phytoextraction and 3) soil fertility restoration. Chemical fertility was monitored by measuring soil C while soil biological fertility was estimated by quantifying the abundance of bacterial functional genes regulating nitrogen fixation (nifH) and nitrification (amoA). Giant reed above-ground growth on the polluted soils was slightly lower (-16%) than on a non-polluted soil, with a preferential storage of biomass in the rhizome acting as a survival strategy in limiting growing conditions. Humic acids improved plant stress tolerance and production levels. As aerial biomass (shoots) did not accumulate PTEs, the plant in question can be used for bioenergy or biopolymer production. In contrast, below-ground biomass (rhizomes) accumulated PTEs, and can thus be harvested and removed from soil to improve phytoremediation protocols and also used as industrial biofuel. Giant reed growth increased the abundance of N-cycling bacteria and soil C in the rhizospheric soil, as well as reduced soil Pb and Zn EDTA extractable fraction. PMID- 27720599 TI - Persistence in the longitudinal distribution of lotic insects in a changing climate: a tale of two rivers. AB - The longitudinal distribution of many taxa in rivers is influenced by temperature. Here we took advantage of two older datasets on net-spinning caddisflies (Hydropsychidae) from contrasting European rivers to assess changes in species occurrence and relative abundance along the river by resampling the same sites, postulating that an increase in river temperature over the intervening period should have resulted in cool-adapted species retreating into the headwaters and warm adapted species expanding upstream. Distributional changes in the Welsh Usk were slight between 1968/69 and 2010, one rare species appearing at a single headwater site and one warm-adapted species disappearing from the main river. Distributional changes in the French Loire, between 1989-93 and 2005, were similarly modest, with no consistent movement of species up- or downstream. We estimate that the decadal rate of increase in the mean summer daily maximum in the Usk was only 0.1 degrees C at one 'summer cool' headwater site, while a neighbouring 'summer warm' tributary increased by 0.16 degrees C per decade, and the main river by 0.22 degrees C. The Loire is warmer than the Usk and the mean decadal rates of increase, over the period 1989-2005, at three sites along the lower reaches were 0.39, 0.48 and 0.77 degrees C. Increases in stream and river temperature, therefore, were spatially variable and were not associated with consistent upstream movement of species in either of these (very different) rivers. We conclude that either the temperature increases have hitherto been insufficient to affect species distribution or, more speculatively, that it may not be possible for river organisms (that do not respond only to temperature) to move upstream because of a developing spatial mismatch between key habitat characteristics, some of them changing with the climate but others not. PMID- 27720600 TI - Relationship Between Energy Drink Consumption and Nutrition Knowledge in Student Athletes. AB - OBJECTIVE: To identify the relationships between energy drink consumption, nutrition knowledge, and socio-demographic characteristics in a convenience sample of student-athletes. DESIGN: Cross-sectional. SETTING: Online survey. PARTICIPANTS: A total of 194 student-athletes (112 female and 82 male). MAIN OUTCOME MEASURES: Socio-demographic characteristics, knowledge of human nutrition, energy drink consumption habits. ANALYSIS: Chi-square tests of independence, independent t tests, and hierarchical regression analyses were applied. RESULTS: Most student-athletes in the sample (85.5%) did not consume energy drinks, but those who did tended to be male (P = .004), had lower overall knowledge of nutrition (P = .02), and had a lower grade point average (P < .001) than did nonusers. Also, energy drink consumption was associated with the overall nutrition knowledge score when adjusted for socio-demographic characteristics, with nonusers having greater nutrition knowledge (P = .007) than users. CONCLUSIONS AND IMPLICATIONS: Student-athletes tend to refrain from energy drink use but those who use it have a tendency to have lower nutrition knowledge than do nonusers. Therefore, nutrition education targeted toward student-athletes should encompass the consumption of energy drinks because limited evidence shows the benefits of collegiate athletes consuming energy drinks. PMID- 27720601 TI - Low Nutrient Intake and Frailty Among Overweight and Obese Migrant Women From Ethnically Diverse Backgrounds Ages 60 Years and Older: A Mixed-Methods Study. AB - OBJECTIVE: To examine associations between energy/nutrient intakes and frailty in older migrant women, and to explore perceptions of body weight, dietary intake, and physical function. DESIGN: Cross-sectional, mixed-methods study. SETTING: Birmingham, United Kingdom. PARTICIPANTS: Seventy-six first-generation migrant women >= 60 years of age. MAIN OUTCOME MEASURES: Energy/nutrient intakes (assessed by 24-hour dietary recall), frailty (using the frailty phenotype), and links between perceptions of body weight, dietary intake, and physical function (via semi-structured interviews). ANALYSIS: Bivariate and logistic regression analyses examined associations between frailty and low energy/nutrient intakes. Interviews were analyzed using inductive thematic analysis. RESULTS: Seventy-six women completed a 24-hour dietary recall; 46 participated in a semi-structured interview. Low energy intake was associated with frailty (odds ratio [OR], 11.71; 95% confidence interval [CI], 2.36-57.97). After adjusting for energy and other confounders, a low intake of > 3 nutrients was associated with frailty (OR, 6.58; 95% CI, 1.01-43.08). Qualitative data suggest that dietary intake was influenced by concerns about body weight and perceptions that unhealthy foods reduce mobility. CONCLUSIONS AND IMPLICATIONS: Among older migrant women with high prevalence of overweight/obesity, an inadequate dietary intake may be a stronger predictor of frailty than weight loss. Dietary interventions should focus on healthy weight maintenance and optimization of nutritional adequacy and physical function. PMID- 27720602 TI - Evaluating the efficacy of epinastine ophthalmic solution using a conjunctivitis allergen challenge model in patients with birch pollen allergic conjunctivitis. AB - BACKGROUND: The efficacy of epinastine 0.05% ophthalmic solution for pollen allergic conjunctivitis has already been shown in a conjunctival allergen challenge (CAC) test using cedar pollen as a challenge. The present study investigated the efficacy of this solution against birch pollen conjunctivitis in a CAC test. METHODS: Ten adult subjects (eight males and two females) with asymptomatic birch pollen conjunctivitis were enrolled in this study. The average age of the subjects was 41.1 years. This study was conducted during a period without birch pollen dispersion. In each subject, the epinastine 0.05% ophthalmic solution was instilled in one eye, and an artificial tear fluid was instilled in the fellow eye in a double-blind manner. Five minutes or 4 h after the drug instillation, both eyes were challenged with an optimal concentration of birch pollen, and ocular itching and conjunctival hyperemia were then graded. Tears were collected before the drug instillation and 20 min after the pollen challenge, and the histamine level was measured. RESULTS: The ocular itching scores and palpebral conjunctival hyperemia scores of the epinastine-treated eyes were significantly lower than those of the contralateral control eyes when the eyes were pretreated with the drug 4 h before the CAC. There was a significant correlation between the tear histamine level and mean ocular itching score of three time points (3, 5 and 10 min) following the CAC in the control eyes but not the epinastine-treated eyes. CONCLUSIONS: Epinastine is effective in suppressing ocular itching and conjunctival hyperemia in birch pollen conjunctivitis. PMID- 27720603 TI - DSM-IV and DSM-5 Prevalence of Social Anxiety Disorder in a Population Sample of Older People. AB - OBJECTIVES: To examine the prevalence of social anxiety disorders (SAD) with (DSM IV) and without (DSM-5) the person's own assessment that the fear was unreasonable, in a population sample of older adults. Further, to determine whether clinical and sociodemographic correlates of SAD differ depending on the criteria applied. DESIGN: Cross-sectional. SETTING: General population in Gothenburg, Sweden. PARTICIPANTS: A random population-based sample of 75- and 85 year olds (N = 1200) without dementia. MEASUREMENTS: Psychiatric research nurses carried out a semi-structured psychiatric examination including the Comprehensive Psychopathological Rating Scale. DSM-IV SAD was diagnosed with the Mini International Neuropsychiatric Interview. SAD was diagnosed according to DSM-IV and DSM-5 criteria. The 6-month duration criterion in DSM-5 was not applied because of lack of information. Other assessments included the Global Assessment of Functioning (GAF), the Brief Scale for Anxiety (BSA), and the Montgomery Asberg Depression Rating Scale (MADRS). RESULTS: The 1-month prevalence of SAD was 2.5% (N = 30) when the unreasonable fear criterion was defined in accordance with DSM-IV and 5.1% (N = 61) when the DSM-5 criterion was applied. Clinical correlates (GAF, MADRS, and BSA) were worse in SAD cases identified by either procedure compared with all others, and ratings for those reporting unreasonable fear suggested greater (albeit nonsignificant) overall psychopathology. CONCLUSIONS: Shifting the judgment of how reasonable the fear was, from the individual to the clinician, doubled the prevalence of SAD. This indicates that the DSM-5 version might increase prevalence rates of SAD in the general population. Further studies strictly applying all DSM-5 criteria are needed in order to confirm these findings. PMID- 27720604 TI - The electro/Fe3+/peroxydisulfate (PDS) process coupled to activated sludge culture for the degradation of tetracycline. AB - The removal of tetracycline (TC) by electro/Fe3+/peroxydisulfate process combined to the biological treatment is reported in this study. Effect of current density, peroxydisulfate (PDS) concentration, Fe3+ ions concentration and initial tetracycline concentration were investigated. The results indicated that the removal efficiency of TC increased with increasing current density and decreases with tetracycline initial concentration. This effect is attributed to the competition of TC and electrogenerated intermediate compounds for the consumption of oxidizing SO4- radicals. The TC degradation efficiency was improved significantly when the PDS and Fe3+ concentrations increased from 1 to 10 mM and 1-2 mM, respectively. Above 10 mM PDS and 2 mM Fe3+ concentrations, a decrease of TC degradation efficiency was observed. The optimal operating conditions were: 2 mM Fe3+, 0.06 mM TC, 10 mM PDS concentrations and 40 mA cm-2 current density. Under these conditions a total degradation of TC within only 40 min of reaction time and 98% of mineralization yield after 3 h electrolysis were obtained. The biodegradability of the solution after electro/Fe3+/peroxydisulfate pre-treatment showed that BOD5/COD ratio increased from 0.00 initially to 0.42, 0.46 and 0.83 after 4 h, 5 h and 6 h, respectively, namely above the limit of biodegradability (0.4). The enhancement of biodegradability initially from 0.00 to 0.42 and 0.46 after 4 h and 5 h of electrolysis respectively, was confirmed by the biological treatment, since 77.51% and 92.54% of the dissolved organic carbon was removed respectively by coupling Electro/Fe3 +/PDS pre-treatment and a biological treatment. PMID- 27720605 TI - A fuzzy-logic based decision-making approach for identification of groundwater quality based on groundwater quality indices. AB - Due to inherent uncertainties in measurement and analysis, groundwater quality assessment is a difficult task. Artificial intelligence techniques, specifically fuzzy inference systems, have proven useful in evaluating groundwater quality in uncertain and complex hydrogeological systems. In the present study, a Mamdani fuzzy-logic-based decision-making approach was developed to assess groundwater quality based on relevant indices. In an effort to develop a set of new hybrid fuzzy indices for groundwater quality assessment, a Mamdani fuzzy inference model was developed with widely-accepted groundwater quality indices: the Groundwater Quality Index (GQI), the Water Quality Index (WQI), and the Ground Water Quality Index (GWQI). In an effort to present generalized hybrid fuzzy indices a significant effort was made to employ well-known groundwater quality index acceptability ranges as fuzzy model output ranges rather than employing expert knowledge in the fuzzification of output parameters. The proposed approach was evaluated for its ability to assess the drinking water quality of 49 samples collected seasonally from groundwater resources in Iran's Sarab Plain during 2013 2014. Input membership functions were defined as "desirable", "acceptable" and "unacceptable" based on expert knowledge and the standard and permissible limits prescribed by the World Health Organization. Output data were categorized into multiple categories based on the GQI (5 categories), WQI (5 categories), and GWQI (3 categories). Given the potential of fuzzy models to minimize uncertainties, hybrid fuzzy-based indices produce significantly more accurate assessments of groundwater quality than traditional indices. The developed models' accuracy was assessed and a comparison of the performance indices demonstrated the Fuzzy Groundwater Quality Index model to be more accurate than both the Fuzzy Water Quality Index and Fuzzy Ground Water Quality Index models. This suggests that the new hybrid fuzzy indices developed in this research are reliable and flexible when used in groundwater quality assessment for drinking purposes. PMID- 27720606 TI - Influence of high temperature on the performance of aerobic granular sludge in biological treatment of wastewater. AB - The effect of temperature on the efficiency of organics and nutrients removal during the cultivation of aerobic granular sludge (AGS) in biological treatment of synthetic wastewater was studied. With this aim, three 3 L sequencing batch reactors (SBRs) with influent loading rate of 1.6 COD g (L d)-1 were operated at different high temperatures (30, 40 and 50 degrees C) for simultaneous COD, phosphate and ammonia removal at a complete cycle time of 3 h. The systems were successfully started up and progressed to steady state at different cultivation periods. The statistical comparison of COD, phosphate and ammonia for effluent from the three SBRs revealed that there was a significant difference between groups of all the working temperatures of the bioreactors. The AGS cultivated at different high temperatures also positively correlated with the accumulation of elements including carbon, oxygen, phosphorus, silicon, iron, aluminium, calcium and magnesium that played important roles in the granulation process. PMID- 27720607 TI - The Germ Cell Fate of Cynomolgus Monkeys Is Specified in the Nascent Amnion. AB - The germ cell lineage ensures reproduction and heredity. The mechanism for germ cell specification in primates, including humans, has remained unknown. In primates, upon implantation the pluripotent epiblast segregates the amnion, an extra-embryonic membrane eventually ensheathing an embryo, and thereafter initiates gastrulation to generate three germ layers. Here, we show that in cynomolgus monkeys, the SOX17/TFAP2C/BLIMP1-positive primordial germ cells (cyPGCs) originate from the dorsal amnion at embryonic day 11 (E11) prior to gastrulation. cyPGCs appear to migrate down the amnion and, through proliferation and recruitment from the posterior amnion, expand in number around the posterior yolk sac by E17. Remarkably, the amnion itself expresses BMP4 and WNT3A, cytokines potentially critical for cyPGC specification, and responds primarily to them. Moreover, human PGC-like cells in vitro exhibit a transcriptome similar to cyPGCs just after specification. Our study identifies the origin of PGCs and a unique function of the nascent amnion in primates. PMID- 27720609 TI - A C. elegans Thermosensory Circuit Regulates Longevity through crh-1/CREB Dependent flp-6 Neuropeptide Signaling. AB - Sensory perception, including thermosensation, shapes longevity in diverse organisms, but longevity-modulating signals from the sensory neurons are largely obscure. Here we show that CRH-1/CREB activation by CMK-1/CaMKI in the AFD thermosensory neuron is a key mechanism that maintains lifespan at warm temperatures in C. elegans. In response to temperature rise and crh-1 activation, the AFD neurons produce and secrete the FMRFamide neuropeptide FLP-6. Both CRH-1 and FLP-6 are necessary and sufficient for longevity at warm temperatures. Our data suggest that FLP-6 targets the AIY interneurons and engages DAF-9 sterol hormone signaling. Moreover, we show that FLP-6 signaling downregulates ins 7/insulin-like peptide and several insulin pathway genes, whose activity compromises lifespan. Our work illustrates how temperature experience is integrated by the thermosensory circuit to generate neuropeptide signals that remodel insulin and sterol hormone signaling and reveals a neuronal-endocrine circuit driven by thermosensation to promote temperature-specific longevity. PMID- 27720608 TI - Acetylation of VGLL4 Regulates Hippo-YAP Signaling and Postnatal Cardiac Growth. AB - Binding of the transcriptional co-activator YAP with the transcription factor TEAD stimulates growth of the heart and other organs. YAP overexpression potently stimulates fetal cardiomyocyte (CM) proliferation, but YAP's mitogenic potency declines postnatally. While investigating factors that limit YAP's postnatal mitogenic activity, we found that the CM-enriched TEAD1 binding protein VGLL4 inhibits CM proliferation by inhibiting TEAD1-YAP interaction and by targeting TEAD1 for degradation. Importantly, VGLL4 acetylation at lysine 225 negatively regulated its binding to TEAD1. This developmentally regulated acetylation event critically governs postnatal heart growth, since overexpression of an acetylation refractory VGLL4 mutant enhanced TEAD1 degradation, limited neonatal CM proliferation, and caused CM necrosis. Our study defines an acetylation-mediated, VGLL4-dependent switch that regulates TEAD stability and YAP-TEAD activity. These insights may improve targeted modulation of TEAD-YAP activity in applications from cardiac regeneration to cancer. PMID- 27720610 TI - Tbx2 and Tbx3 Act Downstream of Shh to Maintain Canonical Wnt Signaling during Branching Morphogenesis of the Murine Lung. AB - Numerous signals drive the proliferative expansion of the distal endoderm and the underlying mesenchyme during lung branching morphogenesis, but little is known about how these signals are integrated. Here, we show by analysis of conditional double mutants that the two T-box transcription factor genes Tbx2 and Tbx3 act together in the lung mesenchyme to maintain branching morphogenesis. Expression of both genes depends on epithelially derived Shh signaling, with additional modulation by Bmp, Wnt, and Tgfbeta signaling. Genetic rescue experiments reveal that Tbx2 and Tbx3 function downstream of Shh to maintain pro-proliferative mesenchymal Wnt signaling, in part by direct repression of the Wnt antagonists Frzb and Shisa3. In combination with our previous finding that Tbx2 and Tbx3 repress the cell-cycle inhibitors Cdkn1a and Cdkn1b, we conclude that Tbx2 and Tbx3 maintain proliferation of the lung mesenchyme by way of at least two molecular mechanisms: regulating cell-cycle regulation and integrating the activity of multiple signaling pathways. PMID- 27720611 TI - Cellular Allometry of Mitochondrial Functionality Establishes the Optimal Cell Size. AB - Eukaryotic cells attempt to maintain an optimal size, resulting in size homeostasis. While cellular content scales isometrically with cell size, allometric laws indicate that metabolism per mass unit should decline with increasing size. Here we use elutriation and single-cell flow cytometry to analyze mitochondrial scaling with cell size. While mitochondrial content increases linearly, mitochondrial membrane potential and oxidative phosphorylation are highest at intermediate cell sizes. Thus, mitochondrial content and functional scaling are uncoupled. The nonlinearity of mitochondrial functionality is cell size, not cell cycle, dependent, and it results in an optimal cell size whereby cellular fitness and proliferative capacity are maximized. While optimal cell size is controlled by growth factor signaling, its establishment and maintenance requires mitochondrial dynamics, which can be controlled by the mevalonate pathway. Thus, optimization of cellular fitness and functionality through mitochondria can explain the requirement for size control, as well as provide means for its maintenance. PMID- 27720613 TI - An open-label randomized controlled clinical trial for comparison of continuous phenylephrine versus norepinephrine infusion in prevention of spinal hypotension during cesarean delivery. AB - BACKGROUND: During spinal anesthesia for cesarean delivery phenylephrine is the vasopressor of choice but can cause bradycardia. Norepinephrine has both beta- and alpha-adrenergic activity suitable for maintaining blood pressure with less bradycardia. We hypothesized that norepinephrine would be superior to phenylephrine, requiring fewer rescue bolus interventions to maintain blood pressure. METHODS: Eighty-five parturients having spinal anesthesia for elective cesarean delivery were randomized to Group P (phenylephrine 0.1MUg/kg/min) or Group N (norepinephrine 0.05MUg/kg/min) fixed-rate infusions. Rescue bolus interventions of phenylephrine 100MUg for hypotension, or ephedrine 5mg for bradycardia with hypotension, were given as required to maintain systolic blood pressure. Maternal hemodynamic variables were measured non-invasively. RESULTS: There was no difference between groups in the proportion of patients who required rescue vasopressor boluses (Group P: 65.8% [n=25] vs. Group N: 48.8% [n=21], P=0.12). The proportion of patients who received ?1 bolus of phenylephrine was similar between groups (Group P: 52.6% [n=20] vs. Group N: 46.5% [n=20], P=0.58). However, more patients received ?1 bolus of ephedrine in the phenylephrine group (Group P: 23.7% [n=9] vs. Group N: 2.3% [n=1], P<0.01). The incidence of emesis was greater in the phenylephrine group (Group P: 26.3% vs. Group P: 16.3%, P<0.001). Hemodynamic parameters including heart rate, the incidence of bradycardia, blood pressure, cardiac output, cardiac index, stroke volume, and systemic vascular resistance and neonatal outcome were similar between groups (all P<0.05). CONCLUSION: Norepinephrine fixed-rate infusion has efficacy for preventing hypotension and can be considered as an alternative to phenylephrine. PMID- 27720614 TI - Stimulation of contractions in pregnant human myometrium is associated with 5-HT3 receptors. AB - BACKGROUND: Serotonin (5-HT) is known to play an important role in regulating uterine contractions. However, the specific receptors involved have not been well characterized. We evaluated whether 5-HT3 receptors exist in human myometrium, and their effects on myometrial contractility when stimulated by a 5-HT3 agonist. METHODS: Four tissue samples taken from patients undergoing hysterectomy (n=2) and elective cesarean delivery (n=2) were used to detect expression of 5-HT3 receptors on the myometrium using western blotting. For isometric tension measurement, another 12 myometrial strips obtained from patients undergoing elective cesarean delivery were randomly divided into a control group (Group CON) and an RS56812 group (Group RG). In increasing doses from 10-7M to 10-4M, RS56812, a 5-HT3 receptor agonist, was used to investigate the contractile effects after bonding to the 5-HT3 receptor, following which the effects of granisetron were assessed. Amplitude, interval and duration of myometrial contractions were recorded. RESULTS: Proteins with a molecular mass of 55kDa, consistent with 5-HT3 receptors, were detected both on non-pregnant and late pregnant human uteri. RS56812 increased the contractile amplitude at concentrations of 10-6M, 10-5M and 10-4M, achieving maximum effect at 10-5M. A prolonged contractile interval was detected at the concentration of 10-4M. However, RS56812 showed no significant effect on contraction duration. Granisetron did not reverse the contractile effects induced by RS56812. CONCLUSION: 5-HT3 receptors are expressed on non-pregnant and pregnant uteri. RS56812 enhanced myometrial contractions, but this was not affected by granisetron, the mechanism of which requires further investigation.

AB - The amyloid state of protein organization is typically associated with debilitating human neuropathies and is seldom observed in physiology. Here, we uncover a systemic program that leverages the amyloidogenic propensity of proteins to regulate cell adaptation to stressors. On stimulus, cells assemble the amyloid bodies (A-bodies), nuclear foci containing heterogeneous proteins with amyloid-like biophysical properties. A discrete peptidic sequence, termed the amyloid-converting motif (ACM), is capable of targeting proteins to the A bodies by interacting with ribosomal intergenic noncoding RNA (rIGSRNA). The pathological beta-amyloid peptide, involved in Alzheimer's disease, displays ACM like activity and undergoes stimuli-mediated amyloidogenesis in vivo. Upon signal termination, elements of the heat-shock chaperone pathway disaggregate the A bodies. Physiological amyloidogenesis enables cells to store large quantities of proteins and enter a dormant state in response to stressors. We suggest that cells have evolved a post-translational pathway that rapidly and reversibly converts native-fold proteins to an amyloid-like solid phase.

AB - Four to six percent of plants, distributed over different angiosperm families, entice pollinators by deception [1]. In these systems, chemical mimicry is often used as an efficient way to exploit the olfactory preferences of animals for the purpose of attracting them as pollinators [2,3]. Here, we report a very specific type of chemical mimicry of a food source. Ceropegia sandersonii (Apocynaceae), a deceptive South African plant with pitfall flowers, mimics attacked honeybees. We identified kleptoparasitic Desmometopa flies (Milichiidae) as the main pollinators of C. sandersonii. These flies are well known to feed on honeybees that are eaten by spiders, which we thus predicted as the model chemically mimicked by the plant. Indeed, we found that the floral scent of C. sandersonii is comparable to volatiles released from honeybees when under simulated attack. Moreover, many of these shared compounds elicited physiological responses in antennae of pollinating Desmometopa flies. A mixture of four compounds-geraniol, 2-heptanone, 2-nonanol, and (E)-2-octen-1-yl acetate-was highly attractive to the flies. We conclude that C. sandersonii is specialized on kleptoparasitic fly pollinators by deploying volatiles linked to the flies' food source, i.e., attacked and/or freshly killed honeybees. The blend of compounds emitted by C. sandersonii is unusual among flowering plants and lures kleptoparasitic flies into the trap flowers. This study describes a new example of how a plant can achieve pollination through chemical mimicry of the food sources of adult carnivorous animals. PMID- 27720618 TI - Stomatal Function Requires Pectin De-methyl-esterification of the Guard Cell Wall. AB - Stomatal opening and closure depends on changes in turgor pressure acting within guard cells to alter cell shape [1]. The extent of these shape changes is limited by the mechanical properties of the cells, which will be largely dependent on the structure of the cell walls. Although it has long been observed that guard cells are anisotropic due to differential thickening and the orientation of cellulose microfibrils [2], our understanding of the composition of the cell wall that allows them to undergo repeated swelling and deflation remains surprisingly poor. Here, we show that the walls of guard cells are rich in un-esterified pectins. We identify a pectin methylesterase gene, PME6, which is highly expressed in guard cells and required for stomatal function. pme6-1 mutant guard cells have walls enriched in methyl-esterified pectin and show a decreased dynamic range in response to triggers of stomatal opening/closure, including elevated osmoticum, suggesting that abrogation of stomatal function reflects a mechanical change in the guard cell wall. Altered stomatal function leads to increased conductance and evaporative cooling, as well as decreased plant growth. The growth defect of the pme6-1 mutant is rescued by maintaining the plants in elevated CO2, substantiating gas exchange analyses, indicating that the mutant stomata can bestow an improved assimilation rate. Restoration of PME6 rescues guard cell wall pectin methyl-esterification status, stomatal function, and plant growth. Our results establish a link between gene expression in guard cells and their cell wall properties, with a corresponding effect on stomatal function and plant physiology. PMID- 27720620 TI - Awakening of a Dormant Cyanobacterium from Nitrogen Chlorosis Reveals a Genetically Determined Program. AB - The molecular and physiological mechanisms involved in the transition of microbial cells from a resting state to the active vegetative state are critically relevant for solving problems in fields ranging from microbial ecology to infection microbiology. Cyanobacteria that cannot fix nitrogen are able to survive prolonged periods of nitrogen starvation as chlorotic cells in a dormant state. When provided with a usable nitrogen source, these cells re-green within 48 hr and return to vegetative growth. Here we investigated the resuscitation of chlorotic Synechocystis sp. PCC 6803 cells at the physiological and molecular levels with the aim of understanding the awakening process of a dormant bacterium. Almost immediately upon nitrate addition, the cells initiated a highly organized resuscitation program. In the first phase, they suppressed any residual photosynthetic activity and activated respiration to gain energy from glycogen catabolism. Concomitantly, they restored the entire translational apparatus, ATP synthesis, and nitrate assimilation. After only 12-16 hr, the cells re-activated the synthesis of the photosynthetic apparatus and prepared for metabolic re wiring toward photosynthesis. When the cells reached full photosynthetic capacity after ~48 hr, they resumed cell division and entered the vegetative cell cycle. An analysis of the transcriptional dynamics during the resuscitation process revealed a perfect match to the observed physiological processes, and it suggested that non-coding RNAs play a major regulatory role during the lifestyle switch in awakening cells. This genetically encoded program ensures rapid colonization of habitats in which nitrogen starvation imposes a recurring growth limitation. PMID- 27720619 TI - A Surveillance System Ensures Crossover Formation in C. elegans. AB - Crossover (CO) recombination creates a physical connection between homologs that promotes their proper segregation at meiosis I (MI). Failure to realize an obligate CO causes homologs to attach independently to the MI spindle and separate randomly, leading to nondisjunction. However, mechanisms that determine whether homolog pairs have received crossovers remain mysterious. Here we describe a surveillance system in C. elegans that monitors recombination intermediates and couples their formation to meiotic progression. Recombination intermediates are required to activate the system, which then delays further processing if crossover precursors are lacking on even one chromosome. The synaptonemal complex, a specialized, proteinaceous structure connecting homologous chromosomes, is stabilized in cis on chromosomes that receive a crossover and is destabilized on those lacking crossovers, a process that is dependent on the function of the polo-like kinase PLK-2. These results reveal a new layer of communication between crossover-committed intermediates and the synaptonemal complex that functions as a cis-acting, obligate, crossover-counting mechanism. PMID- 27720621 TI - Males Can Benefit from Sexual Cannibalism Facilitated by Self-Sacrifice. AB - In a number of species, males are cannibalized by females after mating (reviewed in [1, 2]), and some males actually appear to facilitate their own cannibalism (reviewed in [3]). Such self-sacrifice can evolve if being eaten sufficiently enhances either fertilization success (mating effort) or offspring number or fitness (paternal effort). While there is some support for the mating-effort hypothesis, few studies have found support for paternal effort. We used two experiments to test the paternal-effort hypothesis in the dark fishing spider, Dolomedes tenebrosus. Males of this species provide themselves as a material contribution: they spontaneously die during copulation and are subsequently eaten by females. In support of the paternal-effort predictions, when females were allowed to consume their mating partner, we found large and significant increases in (1) the number, (2) the size, and (3) the survivorship of the offspring. Similar benefits were not seen when females were allowed to consume a cricket in lieu of a male, suggesting that it is the consumption of the male's body per se that is responsible for these fitness benefits. Together, our results suggest that D. tenebrosus males can benefit from self-sacrifice behavior through paternal effort. Such behavior may be particularly likely to evolve when high rates of postcopulatory cannibalism trap males into investing in their first mate instead of investing in acquiring additional matings and/or if strong first-male sperm precedence reduces the benefits of both investing in additional matings and paternity protection.

AB - Beer is one of the oldest alcoholic beverages and is produced by the fermentation of sugars derived from starches present in cereal grains. Contrary to lager beers, made by bottom-fermenting strains of Saccharomyces pastorianus, a hybrid yeast, ale beers are closer to the ancient beer type and are fermented by S. cerevisiae, a top-fermenting yeast. Here, we use population genomics to investigate (1) the closest relatives of top-fermenting beer yeasts; (2) whether top-fermenting yeasts represent an independent domestication event separate from those already described; (3) whether single or multiple beer yeast domestication events can be inferred; and (4) whether top-fermenting yeasts represent non recombinant or recombinant lineages. Our results revealed that top-fermenting beer yeasts are polyphyletic, with a main clade composed of at least three subgroups, dominantly represented by the German, British, and wheat beer strains. Other beer strains were phylogenetically close to sake, wine, or bread yeasts. We detected genetic signatures of beer yeast domestication by investigating genes previously linked to brewing and using genome-wide scans. We propose that the emergence of the main clade of beer yeasts is related with a domestication event distinct from the previously known cases of wine and sake yeast domestication. The nucleotide diversity of the main beer clade more than doubled that of wine yeasts, which might be a consequence of fundamental differences in the modes of beer and wine yeast domestication. The higher diversity of beer strains could be due to the more intense and different selection regimes associated to brewing. PMID- 27720623 TI - Intraspinal Sensory Neurons Provide Powerful Inhibition to Motor Circuits Ensuring Postural Control during Locomotion. AB - In the vertebrate spinal cord, cerebrospinal fluid-contacting neurons (CSF-cNs) are GABAergic neurons whose functions are only beginning to unfold. Recent evidence indicates that CSF-cNs detect local spinal bending and relay this mechanosensory feedback information to motor circuits, yet many CSF-cN targets remain unknown. Using optogenetics, patterned illumination, and in vivo electrophysiology, we show here that CSF-cNs provide somatic inhibition to fast motor neurons and excitatory sensory interneurons involved in the escape circuit. Ventral CSF-cNs respond to longitudinal spinal contractions and induce large inhibitory postsynaptic currents (IPSCs) sufficient to silence spiking of their targets. Upon repetitive stimulation, these IPSCs promptly depress, enabling the mechanosensory response to the first bend to be the most effective. When CSF-cNs are silenced, postural control is compromised, resulting in rollovers during escapes. Altogether, our data demonstrate how GABAergic sensory neurons provide powerful inhibitory feedback to the escape circuit to maintain balance during active locomotion. PMID- 27720624 TI - Starvation-Induced Depotentiation of Bitter Taste in Drosophila. AB - Nutrient deprivation can lead to dramatic changes in feeding behavior, including acceptance of foods that are normally rejected. In flies, this behavioral shift depends in part on reciprocal sensitization and desensitization of sweet and bitter taste, respectively. However, the mechanisms for bitter taste modulation remain unclear. Here, we identify a set of octopaminergic/tyraminergic neurons, named OA-VLs, that directly modulate bitter sensory neuron output in response to starvation. OA-VLs are in close proximity to bitter sensory neuron axon terminals and show reduced tonic firing following starvation. We find that octopamine and tyramine potentiate bitter sensory neuron responses, suggesting that starvation induced reduction in OA-VL activity depotentiates bitter taste. Consistent with this model, artificial silencing of OA-VL activity induces a starvation-like reduction in bitter sensory neuron output. These results demonstrate that OA-VLs mediate a critical step in starvation-dependent bitter taste modulation, allowing flies to dynamically balance the risks associated with bitter food consumption against the threat of severe starvation. PMID- 27720625 TI - Design, construction and validation of a Plasmodium vivax microarray for the transcriptome profiling of clinical isolates. AB - High density oligonucleotide microarrays have been used on Plasmodium vivax field isolates to estimate whole genome expression. However, no microarray platform has been experimentally optimized for studying the transcriptome of field isolates. In the present study, we adopted both bioinformatics and experimental testing approaches to select best optimized probes suitable for detecting parasite transcripts from field samples and included them in designing a custom 15K P. vivax microarray. This microarray has long oligonucleotide probes (60mer) that were in-situ synthesized onto glass slides using Agilent SurePrint technology and has been developed into an 8X15K format (8 identical arrays on a single slide). Probes in this array were experimentally validated and represents 4180 P. vivax genes in sense orientation, of which 1219 genes have also probes in antisense orientation. Validation of the 15K array by using field samples (n=14) has shown 99% of parasite transcript detection from any of the samples. Correlation analysis between duplicate probes (n=85) present in the arrays showed perfect correlation (r2=0.98) indicating the reproducibility. Multiple probes representing the same gene exhibited similar kind of expression pattern across the samples (positive correlation, r>=0.6). Comparison of hybridization data with the previous studies and quantitative real-time PCR experiments were performed to highlight the microarray validation procedure. This array is unique in its design, and results indicate that the array is sensitive and reproducible. Hence, this microarray could be a valuable functional genomics tool to generate reliable expression data from P. vivax field isolates. PMID- 27720626 TI - Detection of Leishmania DNA and blood meal sources in phlebotomine sand flies (Diptera: Psychodidae) in western of Spain: Update on distribution and risk factors associated. AB - Leishmaniosis caused by Leishmania infantum is present in Mediterranean countries, with high prevalence in areas of the center and south of Spain. However, in some regions such as Extremadura (in southwest of Spain), data has not been updated since 1997. The aim of this work was (i) to provide information about the distribution of phlebotomine sand fly species in western of Spain (Extremadura region), (ii) to determine risk factors for the presence of sand fly vectors and (iii) to detect Leishmania DNA and identify blood meal sources in wild caught females. During 2012-2013, sand flies were surveyed using CDC miniature light-traps in 13 of 20 counties in Extremadura. Specimens were identified morphologically and females were used for molecular detection of Leishmania DNA by kDNA, ITS-1 and cyt-B. In addition, blood meals origins were analyzed by a PCR based in vertebrate cyt b gene. A total of 1083 sand flies of both gender were captured and identified. Five species were collected, Phlebotomus perniciosus (60.76%), Sergentomyia minuta (29.92%), P. ariasi (7.11%), P. papatasi (1.48%) and P. sergenti (0.74%). The last three species constitute the first report in Badajoz, the most southern province of Extremadura region. Leishmania DNA was detected in three out of 435 females (one P. pernicious and two S. minuta). Characterization of obtained DNA sequences by phylogenetic analyses revealed close relatedness with Leishmania tarentolae in S. minuta and L. infantum in P. perniciosus. Haematic preferences showed a wide range of hosts, namely: swine, humans, sheep, rabbits, horses, donkeys and turkeys. The simultaneous presence of P. perniciosus and P. ariasi vectors, the analysis of blood meals, together with the detection of L. infantum and in S. minuta of L. tarentolae, confirms the ideal conditions for the transmission of this parasitosis in the western of Spain. These results improve the epidemiological knowledge of leishmaniosis and its vectors in this part of Spain, highlighting the need for ongoing entomological and parasitological surveillance. PMID- 27720627 TI - [Challenges in renal transplantation]. AB - OBJECTIVES: To describe kidney transplantation surgical techniques and to propose strategies in high-risk recipients. MATERIAL AND METHODS: Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov/) and Embase (http://www.embase.com/) database using the following keywords, alone or in association, "renal transplantation; peripheral arterial disease; obesity; third and fourth transplantation; robotic-assisted kidney transplant; anticoagulant therapy; dual kidney transplant". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and case-reports were selected. A total of 1949 articles were analyzed for arterial disease and anticoagulant therapy, 1083 for obesity, 663 for dual kidney transplants, 458 for third and subsequent procedures and 84 for robotic-assisted kidney transplantation. After careful selection, 304 publications were eligible for our review. RESULTS: Surgical assessment of future recipients is a pivotal step to anticipate technical difficulties, to interrupt clopidogrel or direct oral anticoagulants and to propose a revascularization procedure when necessary. Lack of data regarding obese recipients does not allow us to conclude about best surgical care or optimal timing but suggest that an early global management of obesity in chronic kidney disease patients is mandatory to improve access to a successful transplantation. In neurologic bladder and congenital anomalies, urodynamics and bladder function must be assessed prior to the onset of oliguria to intend an early treatment. Urinary diversion may be performed prior to or after transplantation with similar survival outcome and comparable rates of infections. Because of a rigorous selection of donors, the French dual kidney transplant program provides satisfactory outcomes, but fails in convincing surgical teams nationwide. Third and subsequent transplant procedures remain a surgical and immunological challenge, with an increased morbidity and a moderate decline in transplant survival only when donors are extended criteria' with extensive duration of waiting time between procedures. Robotic-assisted kidney transplantation is a recent technique requiring methodical evaluation. CONCLUSION: Kidney transplantation in challenging recipients implies a global understanding of patients' prognosis and benefits versus dialysis, in the context of the attribution of a valuable resource awaited by other patients on waiting list. PMID- 27720628 TI - [Simultaneous pancreas and kidney transplantation]. AB - OBJECTIVES: To perform a State of The Art about the different aspects of pancreas transplantation such as indications, technical features, immunosuppressive strategies and outcomes of simultaneous pancreas-kidney transplantation. MATERIAL AND METHODS: An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords (MESH) : " pancreas transplantation; kidney transplantation; simultaneous pancreas-kidney transplantation; immunosuppression ". Publications obtained were selected based on methodology, language, date of publication (last 20 years) and relevance. Prospective and retrospective studies, in English or French, review articles; meta-analysis and guidelines were selected and analyzed. This search found 2736 articles. After reading titles and abstracts, 23 were included in the text, based on their relevance. RESULTS: These last few years, considerable progresses were done in optimizing indication for pancreas transplantation, as well as surgical improvement and a better used of immunosuppression. In the first part of this article, demographics, indication and pre-transplant evaluation will be described. The different techniques of procurement, preparation and transplantation will then be discussed. Finally, the results and outcomes of pancreas transplantation will be reported. CONCLUSIONS: Despite its morbidity, pancreas transplantation is the optimal treatment of end stage renal disease in diabetic patients under 55. Long-term results and quality of life improvement after pancreas transplantation are excellent. LEVEL OF EVIDENCE: NA. PMID- 27720629 TI - [Living kidney donation]. AB - OBJECTIVES: To review ethical, legal and technical aspects of living kidney donor surgery. MATERIAL AND METHODS: An exhaustive systematic review of the scientific literature was performed in the Medline database (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) using different associations of the following keywords: Donor nephrectomy; Kidney paired donation; Kidney transplantation; Laparoscopic nephrectomy; Living donor; Organs trafficking; Robotic assisted nephrectomy; Vaginal extraction. French legal documents have been reviewed using the government portal (http://www.legifrance.gouv.fr). Articles were selected according to methods, language of publication and relevance. A total of 6421 articles were identified; after careful selection, 161 publications were considered of interest and were eligible for our review. RESULTS: The ethical debate focuses on organ shortage, financial incentive, organ trafficking and the recent data suggesting a small but significant increase risk for late renal disease in donor population. Legal decisions aim to increase the number of kidneys available for donation, such as kidney-paired donation that faces several obstacles in France. Laparoscopic approach became widely used, while robotic assisted donor nephrectomy failed to demonstrate improved outcome as compared with other minimal invasive techniques. CONCLUSION: Minimally invasive living donor nephrectomy aims to limit side effects in the donor without increasing the morbidity in this specific population of healthy persons; long term surveillance to prevent the onset of renal disease in mandatory. PMID- 27720630 TI - An unusual case of Pigmented Villo-Nodular Synovitis of the second toe: A case report and review of literature. AB - Pigmented villo-nodular synovitis (PVNS) is a common disease entity particularly in the knee joint but its incidence in the foot is quite rare. A case of PVNS of the second toe that presented at the outpatient department with an insidious onset and slowly progressive painful swelling of the toe associated with stiffness is presented. The mass was subsequently excised and the diagnosis confirmed by histo-pathology samples. The patient's symptoms improved significantly after the operation. This case is one of the very few reported cases of PVNS involvement of flexor tendon sheath of the foot. It also signifies the importance of clinical suspicions based on the symptoms and examination in reaching to the presumptive diagnosis of the foot pathology and its confirmation by histo-pathological evaluation. PMID- 27720631 TI - Early chemotherapy discontinuation and mortality in older patients with metastatic bladder cancer: The AGEVIM multicenter cohort study. AB - PURPOSE: Median age for the diagnosis of metastatic bladder cancer (MBC) is 73 years. The feasibility of chemotherapy in older patients is controversial. Our objectives were to assess associations linking age to first line chemotherapy regimen selection, early chemotherapy discontinuation, and 1-year mortality in everyday practice. MATERIALS AND METHODS: Between 1999 and 2011, 197 consecutive patients aged>=70 years with MBC referred to 4 hospitals were included in the AGEVIM multicenter cohort. At baseline, we recorded performance status (PS); tumor characteristics; the Charlson Comorbidity Index; and plasma creatinine, hemoglobin, and albumin. Early discontinuation data were available for 193 patients, and overall 1-year mortality for 180 patients. We assessed the probabilities of initial cisplatin-based combination chemotherapy (CCC), early discontinuation (<=2 cycles), and 1-year mortality, using multivariate logistic regression and Cox proportional hazards modeling. RESULTS: Among the 193 patients (mean age: 76+/-4.3y), with 2 metastatic site in median 43.5% received CCC, 36.3% gemcitabine and carboplatin, and 20.2% gemcitabine alone. The probability of CCC decreased with age independently from sex, PS, creatinine clearance, and Charlson Comorbidity Index (P<0.0001), early discontinuation occurred in 24.9% of patients. Factors independently associated with global chemotherapy early discontinuation were age (adjusted odds ratioper additional year = 1.11; 95% CI: 1.02-1.20; P = 0.01) and higher metastatic-site number (adjusted odds ratioper additional site = 1.45; 95% CI: 1.08-1.95; P = 0.01). The number of patients was too small for a robust analysis of factors associated with early chemotherapy discontinuation in each chemotherapy regiment subgroup. Independent predictors of 1-year mortality (median = 9.6 mo) were early discontinuation (adjusted hazard ratio [aHR] = 4.77 [2.85-7.96] when PS<2 and 20.6 [9.43-44.82] when PS>=2; P<0.0001), albumin<35g/l (aHR = 3.06 [1.81-5.17], P = 0.0001), creatinine clearance<30ml/min (aHR = 2.96 [1.45-6.06], P = 0.009), and higher metastatic site number (aHR = 1.34 [1.14-1.56], P<0.0001). CONCLUSION: Less than half of older patients with MBC received initial CCC and 25% had<=2 cycles of chemotherapy. Older age was associated with decreased CCC prescription, independently from known contraindications, and with global chemotherapy early discontinuation, but not with 1-year mortality. PMID- 27720632 TI - Extended Twilight among Isogenic C. elegans Causes a Disproportionate Scaling between Lifespan and Health. AB - Although many genetic factors and lifestyle interventions are known to affect the mean lifespan of animal populations, the physiological variation displayed by individuals across their lifespans remains largely uncharacterized. Here, we use a custom culture apparatus to continuously monitor five aspects of aging physiology across hundreds of isolated Caenorhabditis elegans individuals kept in a constant environment from hatching until death. Aggregating these measurements into an overall estimate of senescence, we find two chief differences between longer- and shorter-lived individuals. First, though long- and short-lived individuals are physiologically equivalent in early adulthood, longer-lived individuals experience a lower rate of physiological decline throughout life. Second, and counter-intuitively, long-lived individuals have a disproportionately extended "twilight" period of low physiological function. While longer-lived individuals experience more overall days of good health, their proportion of good to bad health, and thus their average quality of life, is systematically lower than that of shorter-lived individuals. We conclude that, within a homogeneous population reared under constant conditions, the period of early-life good health is comparatively uniform, and the most plastic period in the aging process is end of-life senescence. PMID- 27720633 TI - Return to sports and functional results after revision anterior cruciate ligament reconstruction by fascia lata autograft. AB - INTRODUCTION: The surgical revision rate following anterior cruciate ligament (ACL) surgery is 3% at 2 years and 4% at 5 years. Revision ACL surgery raises the question of the type of graft to be used. The present study assessed return to sports and functional results after revision ACL reconstruction by fascia lata graft. The hypothesis was that fascia lata provides a reliable graft in revision ACL surgery. MATERIAL AND METHODS: A single-center retrospective continuous study included 30 sports players with a mean age of 26.8+/-8 years undergoing surgical revision for iterative ACL tear between 2004 and 2013. Multi-ligament lesions were excluded. Type and level of sports activity were assessed preoperatively, after primary surgery and at end of follow-up. Clinical assessment used subjective IKDC, Lysholm and KOOS scores. RESULTS: At a mean 4.6+/-1.6 years' follow-up, all patients had resumed sport activity, but only 12 with the same sport at the same level. Median subjective IKDC score increased from 57 [54.3; 58.5] preoperatively to 82 [68.3; 90] at last follow-up, and Lysholm score from 46 [42.3; 51] to 90.5 [80.8; 96.8]; KOOS score at last follow-up was 94.7 [83; 100]. CONCLUSION: Functional results in revision ACL reconstruction by fascia lata graft were satisfactory, with similar return-to-sports rates as with other techniques. Fascia lata provides a reliable graft in revision ACL surgery. LEVEL OF EVIDENCE: IV, retrospective study. PMID- 27720635 TI - Isolated effects of external bath osmolality, solute concentration, and electrical charge on solute transport across articular cartilage. AB - The metabolic function of cartilage primarily depends on transport of solutes through diffusion mechanism. In the current study, we use contrast enhanced micro computed tomography to determine equilibrium concentration of solutes through different cartilage zones and solute flux in the cartilage, using osteochondral plugs from equine femoral condyles. Diffusion experiments were performed with two solutes of different charge and approximately equal molecular weight, namely iodixanol (neutral) and ioxaglate (charge=-1) in order to isolate the effects of solute's charge on diffusion. Furthermore, solute concentrations as well as bath osmolality were changed to isolate the effects of steric hindrance on diffusion. Bath concentration and bath osmolality only had minor effects on the diffusion of the neutral solute through cartilage at the surface, middle and deep zones, indicating that the diffusion of the neutral solute was mainly Fickian. The negatively charged solute diffused considerably slower through cartilage than the neutral solute, indicating a large non-Fickian contribution in the diffusion of charged molecules. The numerical models determined maximum solute flux in the superficial zone up to a factor of 2.5 lower for the negatively charged solutes (charge=-1) as compared to the neutral solutes confirming the importance of charge-matrix interaction in diffusion of molecules across cartilage. PMID- 27720636 TI - Design and biomechanical study of a novel adjustable hemipelvic prosthesis. AB - A pelvic endoprosthesis is commonly used in orthopedic surgeries to reconstruct the pelvis after internal hemipelvectomy. This study presents the detailed design of a novel type I+II+III adjustable hemipelvic prosthesis based on the geometrical features of massive human pelvises. Finite element analysis is conducted to estimate the biomechanical performance of the newly designed adjustable hemipelvic prosthesis. Detailed numerical models of the natural and reconstructed pelvises including related soft tissues are developed. Hip contact forces during normal walking, which is one of the most frequent dynamic activities in daily living, are imposed on the pelvis. Results show that the peak stress observed in the reconstructed pelvis model is still within a low and elastic range below the yielding strength of the cortical bone and Ti6Al4V. No significant difference of the stress transferring route, displacement distributions and principal stress vectors is observed between the reconstructed and natural pelvises. The results indicate that the load transferring function of the partially resected pelvis is able to be reliably recovered by the adjustable hemipelvic prosthesis. The principal stress vectors in both pelvis models predict that bone absorption may not apparently occur in the long run. Long-term biomechanical performance of this newly designed prosthesis may be stability. PMID- 27720634 TI - Coarse-grained simulations of hemolytic peptide delta-lysin interacting with a POPC bilayer. AB - delta-lysin, secreted by a Gram-positive bacterium Staphylococcus aureus, is a 26 residue membrane active peptide that shares many common features with antimicrobial peptides (AMPs). However, it possesses a few unique features that differentiate itself from typical AMPs. In particular, delta-lysin has zero net charge, even though it has many charged residues, and it preferentially lyses eukaryotic cells over bacterial cells. Here, we present the results of coarse grained molecular dynamics simulations of delta-lysin interacting with a zwitterionic membrane over a wide range of peptide concentrations. When the peptides concentration is low, spontaneous dimerization of peptides is observed on the membrane surface, but deep insertion of peptides or pore formation was not observed. However, the calculated free energy of peptide insertion suggests that a small fraction of peptides is likely to be present inside the membrane at the peptide concentrations typically seen in dye efflux experiments. When the simulations with multiple peptides are carried out with a single pre-inserted transmembrane peptide, spontaneous pore formation occurs with a peptide-to-lipid ratio (P/L) as low as P/L=1:42. Inter-peptide salt bridges among the transmembrane peptides seem to play a role in creating compact pores with very low level of hydration. More importantly, the transmembrane peptides making up the pore are constantly pushed to the opposite side of the membrane when the mass imbalance between the two sides of membrane is significant. Thus, the pore is very dynamic, allowing multiple peptides to translocate across the membrane simultaneously. PMID- 27720637 TI - Intraspinal stem cell transplantation for amyotrophic lateral sclerosis: Ready for efficacy clinical trials? AB - Intraspinal stem cell (SC) transplantation represents a new therapeutic approach for amyotrophic lateral sclerosis (ALS) clinical trials. There are considerable difficulties in designing future efficacy trials, some related to the field of ALS and some that are specific to SCs or the mode of delivery. In October 2015, the most controversial points on SC transplantation were addressed during an international workshop intended to bring together international SC and ALS researchers in a public discussion on a topic for which expertise is limited. During the meeting, a discussion was started on the basic structure of the ideal clinical trial testing the efficacy and safety of SC transplantation. The current document includes a number of consensus points reflecting the design of phase II/III clinical trials. PMID- 27720638 TI - Genetic modification of H2AX renders mesenchymal stromal cell-derived dopamine neurons more resistant to DNA damage and subsequent apoptosis. AB - BACKGROUND AIMS: Aberrant production of reactive oxygen species (ROS) and its impact on the integrity of genomic DNA have been considered one of the major risk factors for the loss of dopaminergic neurons in Parkinson's disease (PD). Stem cell transplantation as a strategy to replenish new functional neurons has great potential for PD treatment. However, limited survival of stem cells post transplantation has always been an obstacle ascribed to the existence of neurotoxic environment in PD patients. METHODS: To improve the survival of transplanted stem cells for PD treatment, we explored a new strategy based on the function of the H2AX gene (H2A histone family, member X) in determination of DNA repair and cell apoptosis. We introduced a mutant form Y142F of H2AX into dopamine (DA) neuron-like cells differentiated from bone marrow-derived mesenchymal stromal cells (BMSCs). RESULTS: Expression of H2AX(Y142F) renders DA neuron-like cells more resistant to DNA damage and subsequent cell death induced by ultraviolet irradiation and 1-methyl-4-phenylpyridinium (MPP+) treatment. DISCUSSION: This is a meaningful attempt to improve the sustainability of BMSC derived dopamine neurons under a brain neurotoxic environment. Further studies are needed to evaluate the implications of our findings in stem cell therapy for PD and related diseases. PMID- 27720639 TI - Irradiation of breast cancer cells enhances CXCL16 ligand expression and induces the migration of natural killer cells expressing the CXCR6 receptor. AB - BACKGROUND AIMS: Few studies have examined the migration pattern of natural killer (NK) cells, especially after radiation treatment for cancer. We investigated whether irradiation can modulate the expression of chemokines in cancer cells and the migration of NK cells to irradiated tumor cells. METHODS: The expression of chemokine receptors (CXCR3, CXCR4 and CXCR6) on interleukin-2 (IL-2)/IL-15-activated NK cells was assessed using flow cytometry. Related chemokine ligands (CXCL11, CXCL12 and CXCL16) in human breast cancer cell lines (MCF7, SKBR3 and MDA-MB231) irradiated at various doses were assessed using reverse transcription-polymerase chain reaction (RT-PCR), fluorescence-activated cell sorting (FACS) and enzyme-linked immunosorbent assay (ELISA). The cell-free culture supernatant was collected 96 h after irradiation of breast cancer cell lines for migration and blocking assays. RESULTS: The activated NK cells expressed CXCR6. Expression of the CXCR6 ligand CXCL16 increased in a time- and dose-dependent manner in all analyzed cancer cell lines. CXCL16 expression was statistically significantly enhanced in all breast cancer cell lines on day 3 after 20 Gy irradiation. Activated NK cells migration correlated with CXCL16 concentration (R2 = 0.91; P <0.0001). Significantly enhanced migration of NK cells to irradiated cancer cells was observed for a dose of 20 Gy in MCF7 (P = 0.043) and SKBR3 (P = 0.043) cells, but not in MDA-MB231 (P = 0.225) cells. A blocking assay using a CXCR6 antibody showed a significant decrease in the migration of activated NK cells in all cancer cell lines. CONCLUSIONS: Our data indicate that irradiation induces CXCL16 chemokine expression in cancer cells and enhances the migration of activated NK cells expressing CXCR6 to irradiated breast cancer cells. These results suggest that radiation would improve the anti tumor effect of NK cells through enhanced migration of NK cells to tumor site for the treatment of patients with breast cancer. PMID- 27720641 TI - Magnitude and causes of loss to follow-up among patients with viral hepatitis at a tertiary care hospital in Saudi Arabia. AB - BACKGROUND: Non-adherence with recommended follow-up visits is a major barrier for completing treatment of viral hepatitis and is consequently associated with unfavorable outcomes of health services. OBJECTIVES: To estimate the magnitude and identify perceived reasons and patient characteristics associated with loss to follow-up in a tertiary care setting. METHODS: A two-step cross-sectional study design was used, including a chart review (2011) followed by phone survey (2012). Loss to follow-up was recorded among those who were diagnosed with hepatitis B (HBV) or C (HCV) during 2009-2010 but never returned for recommended/scheduled follow-up appointment(s). RESULTS: A total of 328 patients (202 HBV and 126 HCV) were included in the current analysis. The average age was 49.6+/-17.9years, and 57% were males. Out of 328, 131 (40%) were not advised to do follow-up, and 98 (30%) were not doing follow-up. Perceived reasons for loss to follow-up were as follows: unaware that a follow-up appointment was scheduled (69%), never informed of need for follow-up by healthcare provider (15%), personal belief that follow-up was not necessary (9%), logistical reasons (3%) and other reasons (5%). Loss to follow-up was higher among those who had been diagnosed with HBV, referred by non-liver-related specialty, never advised to follow-up, unaware of their diagnosis, incorrectly identified their type of hepatitis, lacking hepatitis complications, having full medical coverage, pregnant, and those with low knowledge or negative attitude towards hepatitis. CONCLUSIONS: Loss to follow-up is a significant problem among patients with hepatitis in a tertiary care center, with several patient and system failures being implicated. PMID- 27720640 TI - Endophilin-A Deficiency Induces the Foxo3a-Fbxo32 Network in the Brain and Causes Dysregulation of Autophagy and the Ubiquitin-Proteasome System. AB - Endophilin-A, a well-characterized endocytic adaptor essential for synaptic vesicle recycling, has recently been linked to neurodegeneration. We report here that endophilin-A deficiency results in impaired movement, age-dependent ataxia, and neurodegeneration in mice. Transcriptional analysis of endophilin-A mutant mice, complemented by proteomics, highlighted ataxia- and protein-homeostasis related genes and revealed upregulation of the E3-ubiquitin ligase FBXO32/atrogin 1 and its transcription factor FOXO3A. FBXO32 overexpression triggers apoptosis in cultured cells and neurons but, remarkably, coexpression of endophilin-A rescues it. FBXO32 interacts with all three endophilin-A proteins. Similarly to endophilin-A, FBXO32 tubulates membranes and localizes on clathrin-coated structures. Additionally, FBXO32 and endophilin-A are necessary for autophagosome formation, and both colocalize transiently with autophagosomes. Our results point to a role for endophilin-A proteins in autophagy and protein degradation, processes that are impaired in their absence, potentially contributing to neurodegeneration and ataxia. PMID- 27720642 TI - RNA Sequence Context Effects Measured In Vitro Predict In Vivo Protein Binding and Regulation. AB - Many RNA binding proteins (RBPs) bind specific RNA sequence motifs, but only a small fraction (~15%-40%) of RBP motif occurrences are occupied in vivo. To determine which contextual features discriminate between bound and unbound motifs, we performed an in vitro binding assay using 12,000 mouse RNA sequences with the RBPs MBNL1 and RBFOX2. Surprisingly, the strength of binding to motif occurrences in vitro was significantly correlated with in vivo binding, developmental regulation, and evolutionary age of alternative splicing. Multiple lines of evidence indicate that the primary context effect that affects binding in vitro and in vivo is RNA secondary structure. Large-scale combinatorial mutagenesis of unfavorable sequence contexts revealed a consistent pattern whereby mutations that increased motif accessibility improved protein binding and regulatory activity. Our results indicate widespread inhibition of motif binding by local RNA secondary structure and suggest that mutations that alter sequence context commonly affect RBP binding and regulation. PMID- 27720643 TI - Molecular Architecture of SF3b and Structural Consequences of Its Cancer-Related Mutations. AB - SF3b is a heptameric protein complex of the U2 small nuclear ribonucleoprotein (snRNP) that is essential for pre-mRNA splicing. Mutations in the largest SF3b subunit, SF3B1/SF3b155, are linked to cancer and lead to alternative branch site (BS) selection. Here we report the crystal structure of a human SF3b core complex, revealing how the distinctive conformation of SF3b155's HEAT domain is maintained by multiple contacts with SF3b130, SF3b10, and SF3b14b. Protein protein crosslinking enabled the localization of the BS-binding proteins p14 and U2AF65 within SF3b155's HEAT-repeat superhelix, which together with SF3b14b forms a composite RNA-binding platform. SF3b155 residues, the mutation of which leads to cancer, contribute to the tertiary structure of the HEAT superhelix and its surface properties in the proximity of p14 and U2AF65. The molecular architecture of SF3b reveals the spatial organization of cancer-related SF3b155 mutations and advances our understanding of their effects on SF3b structure and function. PMID- 27720647 TI - Sanger Confirmation Is Required to Achieve Optimal Sensitivity and Specificity in Next-Generation Sequencing Panel Testing. AB - Next-generation sequencing (NGS) has rapidly replaced Sanger sequencing as the method of choice for diagnostic gene-panel testing. For hereditary-cancer testing, the technical sensitivity and specificity of the assay are paramount as clinicians use results to make important clinical management and treatment decisions. There is significant debate within the diagnostics community regarding the necessity of confirming NGS variant calls by Sanger sequencing, considering that numerous laboratories report having 100% specificity from the NGS data alone. Here we report our results from 20,000 hereditary-cancer NGS panels spanning 47 genes, in which all 7845 nonpolymorphic variants were Sanger- sequenced. Of these, 98.7% were concordant between NGS and Sanger sequencing and 1.3% were identified as NGS false-positives, located mainly in complex genomic regions (A/T-rich regions, G/C-rich regions, homopolymer stretches, and pseudogene regions). Simulating a false-positive rate of zero by adjusting the variant-calling quality-score thresholds decreased the sensitivity of the assay from 100% to 97.8%, resulting in the missed detection of 176 Sanger-confirmed variants, the majority in complex genomic regions (n = 114) and mosaic mutations (n = 7). The data illustrate the importance of setting quality thresholds for panel testing only after thousands of samples have been processed and the necessity of Sanger confirmation of NGS variants to maintain the highest possible sensitivity. PMID- 27720644 TI - Single-Molecule Imaging Reveals that Rad4 Employs a Dynamic DNA Damage Recognition Process. AB - Nucleotide excision repair (NER) is an evolutionarily conserved mechanism that processes helix-destabilizing and/or -distorting DNA lesions, such as UV-induced photoproducts. Here, we investigate the dynamic protein-DNA interactions during the damage recognition step using single-molecule fluorescence microscopy. Quantum dot-labeled Rad4-Rad23 (yeast XPC-RAD23B ortholog) forms non-motile complexes or conducts a one-dimensional search via either random diffusion or constrained motion. Atomic force microcopy analysis of Rad4 with the beta-hairpin domain 3 (BHD3) deleted reveals that this motif is non-essential for damage specific binding and DNA bending. Furthermore, we find that deletion of seven residues in the tip of beta-hairpin in BHD3 increases Rad4-Rad23 constrained motion at the expense of stable binding at sites of DNA lesions, without diminishing cellular UV resistance or photoproduct repair in vivo. These results suggest a distinct intermediate in the damage recognition process during NER, allowing dynamic DNA damage detection at a distance. PMID- 27720646 TI - Pairing beyond the Seed Supports MicroRNA Targeting Specificity. AB - To identify endogenous miRNA-target sites, we isolated AGO-bound RNAs from Caenorhabditis elegans by individual-nucleotide resolution crosslinking immunoprecipitation (iCLIP), which fortuitously also produced miRNA-target chimeric reads. Through the analysis of thousands of reproducible chimeras, pairing to the miRNA seed emerged as the predominant motif associated with functional interactions. Unexpectedly, we discovered that additional pairing to 3' sequences is prevalent in the majority of target sites and leads to specific targeting by members of miRNA families. By editing an endogenous target site, we demonstrate that 3' pairing determines targeting by specific miRNA family members and that seed pairing is not always sufficient for functional target interactions. Finally, we present a simplified method, chimera PCR (ChimP), for the detection of specific miRNA-target interactions. Overall, our analysis revealed that sequences in the 5' as well as the 3' regions of a miRNA provide the information necessary for stable and specific miRNA-target interactions in vivo. PMID- 27720645 TI - SONAR Discovers RNA-Binding Proteins from Analysis of Large-Scale Protein-Protein Interactomes. AB - RNA metabolism is controlled by an expanding, yet incomplete, catalog of RNA binding proteins (RBPs), many of which lack characterized RNA binding domains. Approaches to expand the RBP repertoire to discover non-canonical RBPs are currently needed. Here, HaloTag fusion pull down of 12 nuclear and cytoplasmic RBPs followed by quantitative mass spectrometry (MS) demonstrates that proteins interacting with multiple RBPs in an RNA-dependent manner are enriched for RBPs. This motivated SONAR, a computational approach that predicts RNA binding activity by analyzing large-scale affinity precipitation-MS protein-protein interactomes. Without relying on sequence or structure information, SONAR identifies 1,923 human, 489 fly, and 745 yeast RBPs, including over 100 human candidate RBPs that contain zinc finger domains. Enhanced CLIP confirms RNA binding activity and identifies transcriptome-wide RNA binding sites for SONAR-predicted RBPs, revealing unexpected RNA binding activity for disease-relevant proteins and DNA binding proteins. PMID- 27720648 TI - Common variant of PDZ domain containing 1 (PDZK1) gene is associated with gout susceptibility: A replication study and meta-analysis in Japanese population. AB - PDZ domain containing 1 (PDZK1) is a scaffold protein that organizes a transportsome and regulates several transporters' functions including urate and drug transporters. Therefore, PDZK1 in renal proximal tubules may affect serum uric acid levels through PDZK1-binding renal urate transporters. Two previous studies in Japanese male population reported that a PDZK1 single nucleotide polymorphism (SNP), rs12129861, was not associated with gout. In the present study, we performed a further association analysis between gout and rs12129861 in a different large-scale Japanese male population and a meta-analysis with previous Japanese population studies. We genotyped rs12129861 in 1210 gout cases and 1224 controls of a Japanese male population by TaqMan assay. As a result, we showed that rs12129861 was significantly associated with gout susceptibility (P = 0.016, odds ratio [OR] = 0.80, 95% confidence interval [CI] 0.67-0.96). The result of the meta-analysis among Japanese populations also showed a significant association (P = 0.013, OR = 0.85, 95%CI 0.75-0.97). Our findings show the significant association between gout susceptibility and common variant of PDZK1 which reportedly regulates the functions of urate transporters in the urate transportsome. PMID- 27720649 TI - Clinicopathologic evaluation of malignancy adjacent to dental implants. AB - OBJECTIVE: The aim of this study was to describe a new case series of peri implant malignancy, review the literature, and discuss the implications of malignancies resembling peri-implantitis. STUDY DESIGN: This study was a retrospective analysis of cases from 2000 to 2016. RESULTS: Seven patients (two males and five females), aged 44 to 89 years, were included, representing 1.5% of oral malignancy cases. Five cases were squamous carcinoma, one of basal cell carcinoma, and one of carcinoma of metastatic origin. Six cases presented with nonulcerated overgrowth, with bone loss in three and massive osteolysis in one. Misinterpretation as peri-implantitis delayed diagnosis in six cases. Risk factors included previous oral malignancy (2), potentially malignant conditions (2), and smoking (1). Of the 47 cases in the English language literature, 85% were squamous cell carcinoma and 8.5% had distant metastasis. Most cases had one or more risk factors. CONCLUSIONS: Peri-implant malignancy may represent up to 1.5% of oral malignancy cases. Clinical features imitating peri-implantitis may delay diagnosis. Lesions failing to respond to treatment, especially in patients with pre-existing risk factors, should significantly increase suspicion. Histopathology is crucial for diagnosis. PMID- 27720650 TI - Clinicobiochemical evaluation of turmeric with black pepper and nigella sativa in management of oral submucous fibrosis-a double-blind, randomized preliminary study. AB - OBJECTIVE: To investigate the effectiveness of turmeric with black pepper and nigella sativa in oral submucous fibrosis (OSMF). STUDY DESIGN: Forty OSMF patients were randomly divided into two groups. The study was performed under a double-blind, randomized design. Group A received turmeric with black pepper and group B received nigella sativa for 3 months. Clinical evaluation was done every 15 days. Patients' serum superoxide dismutase (SOD) levels were assessed before and after treatment and also compared with healthy controls. The response to treatment was analyzed using analysis of variance, paired t test, and unpaired t test. RESULTS: After the treatment, groups A and B showed 3.85 +/- 0.22 mm and 3.6 +/- 0.07 mm improvement in mouth opening, respectively (P < .01); 87.90% and 78.91% reduction in burning sensation, respectively (P < .01); and +0.62 U/mL and +0.74 U/mL improvement in serum SOD levels, respectively (P < .05). The maximum mouth opening achieved was 8 mm in group A and 7 mm in group B. The mean pretreatment SOD level for controls and patients was 3.61 +/- 0.24 U/mL in group A and 2.63 +/- 0.18 U/mL in group B. CONCLUSION: Turmeric with black pepper and nigella sativa improved mouth opening, burning sensation, and SOD levels in the present OSMF study patients; however, further investigations are needed. PMID- 27720651 TI - Second primary cancer after index head and neck squamous cell carcinoma in Northern China. AB - OBJECTIVE: To evaluate the clinicopathologic features, prognostic factors, and management of patients in the North Chinese population with head and neck squamous cell carcinoma (HNSCC) who developed a second primary malignancy (SPM). METHODS: This was a retrospective study including 1818 eligible patients between June 1999 and April 2011. RESULTS: A total of 188 HNSCC patients developed SPM. Multiple oral dysplastic lesions (MODLs) (P < .001) were among the risk factors for occurrence of SPM. However, MODLs were closely associated with many mild pathologic features, such as early T stage (P < .001), early N stage (P = .036), good pathologic differentiation (P < .001), and mild growth pattern (P < .001). Interestingly, multivariate survival analysis showed that SPM patients had a better prognosis if they had the characteristics of MODLs (P = .020). CONCLUSIONS: MODLs were a crucial risk factor leading to the occurrence of oral SPM after an index HNSCC in patients in Northern China. However, SPM patients with the characteristics of MODLs had a better prognosis. PMID- 27720652 TI - In vivo reflectance confocal microscopy for evaluating melanoma of the lip and its differential diagnoses. AB - OBJECTIVE: To improve prebiopsy diagnostic accuracy and surgical management of pigmented appearing lesions on the lips, particularly melanoma, using in vivo reflectance confocal microscopy (RCM). STUDY DESIGN: Prospective case series over a 12-month period between 2015 and 2016. The setting was two specialist dermatology referral centers with expertise in confocal microscopy. The study population was a consecutive sample of patients with pigmentation of the lip for which the cause was uncertain clinically, whose differential diagnosis included melanoma, and who had undergone both in vivo RCM and subsequent biopsy. The outcome measures were RCM features, dermoscopy features, and histopathological diagnosis. Results were reported by descriptive analysis and correlations made between RCM features and histopathology. RESULTS: Eight patients were recruited for the study. In vivo RCM facilitated the targeting of small biopsies to identify two in situ oral melanoma recurrences and successfully mapped an in situ oral melanoma before wide excision. Suprabasal dendritic pagetoid cells and epidermal disarray on RCM were useful indicators for in situ melanoma of the lip. Previously described dermoscopy features for mucosal melanoma were not very helpful in diagnosing melanoma in our series. Challenges included evaluating inflamed lesions with pigment incontinence. CONCLUSIONS: RCM can assist in the diagnosis and management of pigmented lip lesions, but additional studies are required to further evaluate these initial observations.

PMID- 27720655 TI - Osteoblast-like cells with different embryologic origins behave differently in increasing zoledronic acid concentrations: a pilot study in pigs. AB - OBJECTIVE: We compared the intraindividual effects of increasing zoledronic acid (ZA) concentrations on osteoblast-like cells with different embryologic origins. STUDY DESIGN: Cultured osteoblast-like cells from mandible and iliac crest bone samples of domestic pigs were exposed to increasing concentrations of ZA (0, 10 8, 10-6, and 10-4 M). Proliferation was assessed by cell counting. Receptor activator of nuclear factor kB ligand and osteoprotegerin (OPG) messenger RNA expression were assessed at 0, 1, 4, 7, and 10 days. RESULTS: The OPG expression level was higher in the iliac crest than in the mandible. Neither ZA concentration nor the cells' origin affected the expression of receptor activator of nuclear factor kB ligand. At 10-6 M, OPG expression from both locations reached the same level after 7 days of cultivation, as OPG expression increased to a greater extent in the mandible in comparison to the iliac crest. CONCLUSION: Cultured mandibular osteoblast-like cells reacted more sensitively to high ZA concentrations than did osteoblast-like cells from the iliac crest. PMID- 27720657 TI - Tumor mass in the palate after bone marrow transplantation. PMID- 27720656 TI - MicroRNA-375 as a biomarker for malignant transformation in oral lesions. AB - OBJECTIVE: Malignant transformation of oral premalignant lesions is the key process in the progression to oral squamous cell carcinoma (OSCC). Previously, we identified miR-7 and miR-21 as candidate oncogenes and miR-375 and miR-494 as candidate tumor suppressors in OSCC. We aim to evaluate these microRNAs as biomarkers of malignant transformation in oral premalignant lesions. STUDY DESIGN: Formalin-fixed, paraffin-embedded samples from progressive premalignant lesions and paired sequential OSCC tumors at the same site were obtained from same patients (n = 31). Total RNA was extracted and analyzed for microRNA levels using real-time polymerase chain reaction. RESULTS: MiR-375 expression in progressive lesions was clearly lower than in nonprogressive control lesions (average eightfold difference, P = .0004). Furthermore, the expression of miR-375 decreased significantly after the progression from premalignant lesion to OSCC (P < .0001). Receiver operating characteristic curve analysis revealed that miR-375 was able to differentiate between progressive and nonprogressive premalignant lesions (P < .0001). CONCLUSIONS: MiR-375 downregulation in oral premalignant lesions is associated with a higher risk of malignant transformation.

PMID- 27720659 TI - A randomized control trial measuring the effectiveness of a mouth-exercising device for mucosal burning in oral submucous fibrosis. AB - OBJECTIVES: To evaluate effect of ice-cream stick exercise regimen with or without a mouth-exercising device (MED) on mucosal burning sensation in oral submucous fibrosis. STUDY DESIGN: In total, 282 patients with oral submucous fibrosis were treated with topical corticosteroid and oral antioxidant and the ice-cream stick exercise regimen. Patients in subgroups A1, A2, and A3 were additionally given a new MED. Patients in subgroups A1 and B1 patients with interincisal distance (IID) of 20 to 35 mm were managed without any additional therapy; patients in subgroups A2 and B2 with IID of 20 to 35 mm were additionally managed with intralesional injections; and those in subgroups A3 and B3 with IID less than 20 mm were managed surgically. Subjective evaluation of decrease in the oral mucosal burning was measured on a visual analogue scale (VAS). Analysis of variance and Tukey's multiple post hoc analysis were carried out to present the results. RESULTS: Patients using the MED, that is, subgroups A1, A2, and A3, showed reduction in burning sensation in the range of 64.8% to 71.1% and 27.8% to 30.9%, whereas in subgroups B1, B2, and B3, reduction in burning sensation ranged from 64.7% to 69.9% and from 29.3% to 38.6% after 6 months. The wo-way analysis of variance indicated statistically significant results in changes in initial VAS scores to 6-monthly VAS scores between MED users and non-MED users. CONCLUSIONS: The MED helps to enhance the rate of reduction of mucosal burning sensation, in addition to the conventional ice-cream stick regimen, as an adjunct to local and surgical treatment.

PMID- 27720661 TI - Comparison of intraoperative blood loss between four different surgical procedures in the treatment of bimaxillary protrusion. AB - OBJECTIVE: This study was aimed at investigating the correlation between intraoperative blood loss and operation-related factors in the treatment of bimaxillary protrusion with four different procedures. STUDY DESIGN: Ninety-four patients were separated into the following four surgical groups: group 1: anterior subapical osteotomy of the maxilla (ASO Mx) + bilateral parasymphyseal osteotomy of the mandible (BPsO Md) + genioplasty (GeP); group 2: ASO Mx + BPsO Md; group 3: ASO Mx + ASO Md + GeP; and group 4: ASO Mx + ASO Md. Patient- and operation-related factors (age, intraoperative blood loss, operation time, and preoperative and postoperative blood parameters) were compared among the four groups. RESULTS: The mean operation time and intraoperative blood loss were 438.7 minutes and 369.9 mL in group 1; 432.5 minutes and 356.5 mL in group 2; 393.3 minutes and 387.3 mL in group 3; and 353.5 minutes and 289.5 mL in group 4. Intergroup differences in intraoperative blood loss were not significant. A significant correlation between intraoperative blood loss and operation time was found in group 4 but not in the other groups. CONCLUSIONS: No significant differences in blood loss were found among the four different surgical procedures in the treatment of bimaxillary protrusion. PMID- 27720662 TI - Inappropriate Fentanyl Prescribing Among Nursing Home Residents in the United States. AB - OBJECTIVE: We quantified transdermal fentanyl prescribing in elderly nursing home residents without prior opioid use or persistent pain, and the association of individual and facility traits with opioid-naive prescribing. DESIGN: Cross sectional study. SETTING: Linked Minimum Data Set (MDS) assessments; Online Survey, Certification and Reporting (OSCAR) records; and Medicare Part D claims. PARTICIPANTS: From a cross-section of all long-stay US nursing home residents in 2008 with an MDS assessment and Medicare Part D enrollment, we identified individuals (>=65 years old) who initiated transdermal fentanyl, excluding those with Alzheimer disease, severe cognitive impairment, cancer, or receipt of hospice care. MEASUREMENTS: We used Medicare Part D to select beneficiaries initiating transdermal fentanyl in 2008 and determined whether they were "opioid naive," defined as no opioid dispensing during the previous 60 days. We obtained resident and facility characteristics from MDS and OSCAR records and defined persistent pain as moderate-to-severe, daily pain on consecutive MDS assessments at least 90 days apart. We estimated associations of patient and facility attributes and opioid-naive fentanyl initiation using multilevel mixed effects logistic regression modeling. RESULTS: Among 17,052 residents initiating transdermal fentanyl, 6190 (36.3%) were opioid-naive and 15,659 (91.8%) did not have persistent pain. In the regression analysis with adjustments, residents who were older (ages >=95 odds ratio [OR] 1.69, 95% confidence interval [CI] 1.46 1.95) or more cognitively impaired (moderate-to-severe cognitive impairment, OR 1.99, 95% CI 1.73-2.29) were more likely to initiate transdermal fentanyl without prior opioid use. CONCLUSION: Most nursing home residents initiating transdermal fentanyl did not have persistent pain and many were opioid-naive. Changes in prescribing practices may be necessary to ensure Food and Drug Administration warnings are followed, particularly for vulnerable subgroups, such as the cognitively impaired. PMID- 27720663 TI - Performance-Based Assessment of Instrumental Activities of Daily Living: Validation of the Sydney Test of Activities of Daily Living in Memory Disorders (STAM). AB - OBJECTIVES: The distinction between dementia and mild cognitive impairment (MCI) relies upon the evaluation of independence in instrumental activities of daily living (IADL). Self- and informant reports are prone to bias. Clinician-based performance tests are limited by long administration times, restricted access, or inadequate validation. To close this gap, we developed and validated a performance-based measure of IADL, the Sydney Test of Activities of Daily Living in Memory Disorders (STAM). DESIGN: Prospective cohort study (Sydney Memory and Ageing Study). SETTING: Eastern Suburbs, Sydney, Australia. PARTICIPANTS: 554 community-dwelling individuals (54% female) aged 76 and older with normal cognition, MCI, or dementia. MEASUREMENTS: Activities of daily living were assessed with the STAM, administered by trained psychologists, and the informant based Bayer-Activities of Daily Living Scale (B-ADL). Depressive symptoms were measured with the Geriatric Depression Scale (15-item version). Cognitive function was assessed with a comprehensive neuropsychological test battery. Consensus diagnoses of MCI and dementia were made independently of STAM scores. RESULTS: The STAM showed high interrater reliability (r = 0.854) and test-retest reliability (r = 0.832). It discriminated significantly between the diagnostic groups of normal cognition, MCI, and dementia with areas under the curves ranging from 0.723 to 0.948. A score of 26.5 discriminated between dementia and nondementia with a sensitivity of 0.831 and a specificity of 0.864. Correlations were low with education (r = 0.230) and depressive symptoms (r = -0.179), moderate with the B-ADL (r = -0.332), and high with cognition (ranging from r = 0.511 to r = 0.594). The mean time to complete the STAM was 16 minutes. CONCLUSIONS: The STAM has good psychometric properties. It can be used to differentiate between normal cognition, MCI, and dementia and can be a helpful tool for diagnostic classification both in clinical practice and research. PMID- 27720664 TI - Pharmacological management of acute kidney injury and chronic kidney disease in neonates. AB - Both acute kidney injury (AKI) and chronic kidney disease (CKD) are seen more frequently in the neonatal intensive care unit (NICU) as advances in supportive care improve the survival of critically ill infants as well as those with severe, congenital kidney and urinary tract anomalies. Many aspects of the infant's care, including fluid balance, electrolyte and mineral homeostasis, acid-base balance, and growth and nutrition require close monitoring by and collaboration among neonatologists, nephrologists, dieticians, and pharmacologists. This educational review summarizes the therapies widely used for neonates with AKI and CKD. Use of these therapies is extrapolated from data in older children and adults or based on clinical experience and case series. There is a critical need for more research on the use of therapies in infants with kidney disease as well as for the development of drug delivery systems and preparations scaled more appropriately for these small patients.

AB - Over the last century, many surgical treatments have been developed in the orthopedic field, including treatments of anterior cruciate ligament (ACL) injuries. These treatments ideally evolve in a process of trial and error with prospective comparison of new treatments to the current treatment standard. However, these evolutions are sometimes not linear and periodically undergo paradigm shifts. In this article, we review the evolution of ACL treatment and explain how it underwent a paradigm shift. Open primary ACL repair was the most common treatment in the 1970s and 1980s, but because multiple studies noted deterioration of outcomes at mid-term follow-up, in addition to several randomized clinical trials (RCTs) that noted better outcomes following ACL reconstruction, the open primary repair technique was abandoned. At the end of the primary repair era, however, several studies showed that outcomes of open primary repair were good to excellent and did not deteriorate when this technique was selectively performed in patients with proximal ACL tears, whereas primary repair led to disappointing and unpredictable results in patients with mid substance tears. Unfortunately, enrollment of patients in the aforementioned RCTs was already finished, ultimately leading to abandoning of open primary repair, despite the advantages of ligament preservation. In this review, we discuss (I) why the evolution of ACL treatment underwent a paradigm shift, (II) which factors may have played a role in this and (III) what the future role of arthroscopic primary ACL repair is in the evolution of ACL treatments.

PMID- 27720669 TI - 13C dynamic nuclear polarization for measuring metabolic flux in endothelial progenitor cells. AB - Endothelial progenitor cells (EPCs) represent a heterogeneous cell population that is believed to be involved in vasculogenesis. With the purpose of enhancing endothelial repair, EPCs could have a potential for future cell therapies. Due to the low amount of EPCs in the peripheral circulating blood, in vitro expansion is needed before administration to recipients and the effects of in vitro culturing is still an under-evaluated field with little knowledge of how the cells change over time in culture. The aim of this study was to use hyperpolarised carbon-13 magnetic resonance spectroscopy to profile important metabolic pathways in a population of progenitor cells and to show that cell culturing in 3D scaffolds seem to block the metabolic processes that leads to cell senescence. The metabolic breakdown of hyperpolarized [1-13C]pyruvate was followed after injection of the substrate to a bioreactor system with EPCs either adhered to 3D printed scaffolds or kept in cell suspension. The pyruvate-to-lactate conversion was elevated in suspension of EPCs compared to the EPCs adhered to scaffolds. Furthermore in the setup with EPCs in suspension, an increase in lactate production was seen over time indicating that the older the cultures of EPCs was before using the cells for cell suspension experiments, the more lactate they produce, compared to a constant lactate level in the cells adhered to scaffolds. It could therefore be stated that cells grown first in 2D culture and subsequent prepared for cell suspension show a metabolism with higher lactate production consistent with cells senescence processes compared to cells grown first at 2D culture and subsequent in the 3D printed scaffolds, where metabolism shows no sign of metabolic shifting during the monitored period. PMID- 27720670 TI - Overexpression of soluble ADAM33 promotes a hypercontractile phenotype of the airway smooth muscle cell in rat. AB - A disintegrin and metalloproteinase 33 (ADAM33) has been identified as a susceptibility gene for asthma, but details of the causality are not fully understood. We hypothesize that soluble ADAM33 (sADAM33) overexpression can alter the mechanical behaviors of airway smooth muscle cells (ASMCs) via regulation of the cell's contractile phenotype, and thus contributes to airway hyperresponsiveness (AHR) in asthma. To test this hypothesis, we either overexpressed or knocked down the sADAM33 in rat ASMCs by transfecting the cells with sADAM33 coding sequence or a small interfering RNA (siRNA) that specifically targets the ADAM33 disintegrin domain, and subsequently assessed the cells for stiffness, contractility and traction force, together with the expression level of contractile and proliferative phenotype markers. We also investigated whether these changes were dependent on Rho/ROCK pathway by culturing the ASMCs either in the absence or presence of ROCK inhibitor (H1152). The results showed that the ASMCs with sADAM33 overexpression were stiffer and more contractile, generated greater traction force, exhibited increased expression levels of contractile phenotype markers and markedly enhanced Rho activation. Furthermore these changes were largely attenuated when the cells were cultured in the presence of H-1152. However, the knock-down of ADAM33 seemed insufficient to influence majority of the mechanical behaviors of the ASMCs. Taken together, we demonstrated that sADAM33 overexpression altered the mechanical behaviors of ASMCs in vitro, which was most likely by promoting a hypercontractile phenotype transition of ASMCs through Rho/ROCK pathway. This revelation may establish the previously missing link between ADAM33 expression and AHR, and also provide useful insight for targeting sADAM33 in asthma prevention and therapy. PMID- 27720671 TI - Genotoxic and cytotoxic effects of the environmental pollutant 3 nitrobenzanthrone on bladder cancer cells. AB - 3-Nitrobenzanthrone (3-NBA), a potential human carcinogen, is present in diesel exhaust. The main metabolite of 3-NBA, 3-aminobenzanthrone, was detected in urine of miners occupationally exposed to diesel emissions. Environmental and occupational factors play an important role in development of bladder cancer (BC), one of the most frequent malignancies. It is expected that exposure of urothelium to 3-NBA and its metabolites may induce BC initiation and/or progression. To test this hypothesis, we studied geno- and cytotoxicity of 3-NBA using an in vitro BC model. 3-NBA induced higher levels of DNA adducts, reactive oxygen species and DNA breaks in aggressive T24 cells than in more differentiated RT4 cells. To understand the nature of this difference we examined the role of several enzymes that were identified as 3-NBA bio activators. However, the difference in DNA adduct formation cannot be directly linked to the different activity of any of the examined enzymes. Conversely, the difference of tested cell lines in p53 status can partly explain the distinct levels of 3-NBA-DNA adducts and DNA damage induced by 3-NBA. Therefore, we assume that more aggressive T24 cells are more predisposed for DNA adduct formation, DNA damage and, possibly, mutations and as a result further tumorigenesis.

AB - BACKGROUND/PURPOSE: Gastric cancer (GC) is one of the most common malignant cancers worldwide. However, little is known about the molecular process underlying this disease and its progression. This study investigated correlations between the expression of a mitochondrial inner membrane protein translocase of inner mitochondrial membrane 9 homolog (TIMM9) and various clinicopathologic parameters as well as patients' survival. METHODS: Gastric tissue samples were obtained from 140 patients with GC and expression levels of TIMM9 were analyzed through immunohistochemistry. Paired t tests were used to analyze the differences in the expression levels of TIMM9 in both tumor and nontumor tissues for each patient. Two-tailed chi2 tests were performed to determine whether the differences in TIMM9 expression and clinicopathologic parameters were significant. Time-to-event endpoints for clinicopathologic parameters were plotted using the Kaplan-Meier method, and statistical significance was determined using univariate log-rank tests. Cox proportional hazard model was used for multivariate analysis to determine the independence of prognostic effects of TIMM9 expression. RESULTS: A borderline association was found between overexpression of TIMM9 and vascular invasion (p = 0.0887). Patients with high expression levels of TIMM9 achieved a significantly lower disease-free survival rate compared with those with low expression levels (p = 0.005). Multivariate Cox regression analysis showed that overexpression of TIMM9 was an independent prognostic marker for GC (p = 0.011). CONCLUSION: Overexpression of TIMM9 can be used as a marker to predict the outcome of patients with GC. PMID- 27720674 TI - No increase in childhood leukaemia near UK nuclear sites.

AB - Methylobacterium species are methylotrophic bacteria that widely inhabit plant surfaces. In addition to studies on methylotrophs as model organisms, research has also been conducted on their mechanism of plant growth promotion as well as the species-species specificity of plant-microbe interaction. We employed whole cell matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (WC MS) analysis, which enables the rapid and accurate identification of bacteria at the species level, to identify Methylobacterium isolates collected from the rice seeds of different cultivars harvested in Japan, Thailand, and Kenya. Rice seeds obtained from diverse geographical locations showed different communities of Methylobacterium species. We found that M. fujisawaense, M. aquaticum, M. platani, and M. radiotolerans are the most frequently isolated species, but none were isolated as common species from 18 seed samples due to the highly biased communities in some samples. These findings will contribute to the development of formulations containing selected species that promote rice growth, though it may be necessary to customize the formulations depending on the cultivars and farm conditions. PMID- 27720676 TI - The Assembly Pathway of Mitochondrial Respiratory Chain Complex I. AB - Mitochondrial complex I is the largest integral membrane enzyme of the respiratory chain and consists of 44 different subunits encoded in the mitochondrial and nuclear genome. Its biosynthesis is a highly complicated and multifaceted process involving at least 14 additional assembly factors. How these subunits assemble into a functional complex I and where the assembly factors come into play is largely unknown. Here, we applied a dynamic complexome profiling approach to elucidate the assembly of human mitochondrial complex I and its further incorporation into respiratory chain supercomplexes. We delineate the stepwise incorporation of all but one subunit into a series of distinct assembly intermediates and their association with known and putative assembly factors, which had not been implicated in this process before. The resulting detailed and comprehensive model of complex I assembly is fully consistent with recent structural data and the remarkable modular architecture of this multiprotein complex. PMID- 27720678 TI - A novel missense mutation of NDP in a Chinese family with X-linked familial exudative vitreoretinopathy. AB - Familial exudative vitreoretinopathy (FEVR) is a hereditary ocular disorder characterized by a failure of peripheral retinal vascularization. In this report, we describe a novel missense mutation of the Norrie disease gene (NDP) in a Chinese family with X-linked FEVR. Ophthalmologic evaluation was performed on four male patients and seven unaffected individuals after informed consent was obtained. Venous blood was collected from the 11 members of this family, and genomic DNA was extracted using standard methods. The coding exons 2 and 3 and their corresponding exon-intron junctions of NDP were amplified by polymerase chain reaction and then subjected to direct DNA sequencing. A novel missense mutation (c.310A>C) in exon 3, leading to a lysine-to-glutamine substitution at position 104 (p.Lys104Gln), was identified in all four patients with X-linked FEVR. Three unaffected female individuals (III2, IV3, and IV11) were found to be carriers of the mutation. This mutation was not detected in other unaffected individuals. The mutation c.310A>C (p.Lys104Gln) in exon 3 of NDP is associated with FEVR in the studied family. This result further enriches the mutation spectrum of FEVR. PMID- 27720677 TI - Phagocytosis of bone marrow derived macrophages is controlled by phosphoinositide 3-kinase gamma. AB - Due to their ability to phagocytise invading microbes macrophages play a key role in the innate and acquired immune system. In this article the role of phosphoinositide 3-kinase gamma (PI3Kgamma) for phagocytosis was studied in bone marrow derived macrophages (BMDM). By using genetic and pharmacological approaches our data clearly demonstrate PI3Kgamma is acting as a mediator of macrophage phagocytosis. Phagocytosis of LPS activated BMDM was reduced in PI3Kgamma depleted primary BMDM or macrophage cell line J774. Depletion of other class I phosphoinositide 3-kinases did not alter phagocytic activity. Partial reduction of the phagocytic index of BMDM expressing kinase inactive PI3Kgamma indicate a lipid-kinase independent role of the PI3Kgamma protein. Since inhibition of PI3Kgamma interaction partner phosphodiesterase PDE3B reduced BMDM phagocytosis and PI3Kgamma knock out super stimulated cAMP level, our data reveal that PI3Kgamma protein mediated suppression of cAMP signalling is a critical for efficient phagocytosis of macrophages. PMID- 27720679 TI - Fetuin-A downregulates adiponectin through Wnt-PPARgamma pathway in lipid induced inflamed adipocyte. AB - Adiponectin secreted from adipocytes is an anti-diabetic and anti-atherogenic adipokine. Adiponectin level is known to fall significantly in obesity induced type 2 diabetes which worsen insulin sensitivity because of aberrant lipid management. However, underlying mechanism of adiponectin decrease in obese diabetic condition is yet unclear. We report here that lowering of plasma adiponectin coincided with the higher Fetuin A (FetA) level in high fat diet (HFD) induced obese diabetic mice. Knock down of FetA gene (FetAKD) elevated adiponectin level markedly in HFD mice, while reinforcement of FetA into FetAKDHFD mice reduced its level again. These results indicate FetA's involvement in the lowering of adiponectin level in obesity induced diabetic mice. Our findings to understand how FetA could affect adiponectin decrease demonstrated that FetA could enhance Wnt3a expression in the adipocyte of HFD mice. FetA addition to 3T3L1 adipocyte incubation elevated Wnt3a expression in a dose dependent manner. Overexpression of Wnt3a by FetA inhibited PPARgamma and adiponectin. FetA failed to reduce PPARgamma and adiponectin in Wnt3a gene knocked down 3T3L1' adipocytes. All these suggest that FetA mediate its inhibitory effect on adiponectin through Wnt3a-PPARgamma pathway. Inhibition of adiponectin expression through FetA and Wnt3a significantly compromised with the activation of AMPK and its downstream signalling molecules which adversely affected lipid management causing loss of insulin sensitivity. Downregulation of adiponectin in inflamed adipocyte by FetA through the mediation of Wnt3a and PPARgamma is a new report. PMID- 27720680 TI - High throughput solid phase microextraction: A new alternative for analysis of cellular lipidome? AB - A new SPME method for untargeted lipidomic study of cell line cultures was proposed for the first time. In this study the feasibility to monitor changes in lipid profile after external stimuli was demonstrated and compared to the conventional Bligh & Dyer method. The human hepatocellular carcinoma (HCC) cell line was used as a model. The obtained results provided a list of up-regulated and down-regulated lipids through a comparison between control (non-stimulated) cells versus the group of cells treated with polyunsaturated fatty acid (20:5). Use of the SPME technique yielded a list of 77 lipid species whose concentrations were recognized to be significantly different between control and treated cells, from which 63 lipids were up-regulated in treated cells. In general, the list was comparable to the peer list obtained by the Bligh & Dyer method. However, more diversity of lipid classes and subclasses such as LPC, sphingomyelins, ceramides, and prenol lipids were observed with the application of the SPME method. Method precision for the SPME approach was within the acceptable analytical range (5-18% RSD) for all detected lipids, which was advantageous over solvent extraction applied. The evaluation of ionization efficiency indicated no matrix effect for the SPME technique, while Bligh & Dyer presented significant ionization suppression for low abundant species such as LysoPC, PG, ceramides, and sphingomyelins, and ionization enhancement for high abundant phospholipids such as PE. PMID- 27720681 TI - Palmitoylethanolamide reduces inflammation and itch in a mouse model of contact allergic dermatitis. AB - In mice, 2,4-dinitrofluorobenzene (DNFB) induces contact allergic dermatitis (CAD), which, in a late phase, is characterized by mast cell (MC) infiltration and angiogenesis. Palmitoylethanolamide (PEA), an endogenous anti-inflammatory molecule, acts by down-modulating MCs following activation of the cannabinoid CB2 receptor and peroxisome proliferator-activated receptor-alpha (PPAR-alpha). We have previously reported the anti-inflammatory effect of PEA in the early stage of CAD. Here, we examined whether PEA reduces the features of the late stage of CAD including MC activation, angiogenesis and itching. After sensitization to DNFB, female C57BL/6J mice underwent to three DNFB challenges at days 5, 12 and 19 and treatments were given at each challenge and for two more days. CAD was expressed as Delta increase in ear thickness between challenged and un-challenged mice. PEA (5mg/kg/i.p.) reduced: i) the DNFB-induced Delta increase; ii) the number of MCs per tissue area; iii) the expression of VEGF and its receptor Flk 1. These effects were reversed by co-administration of AM630 (1mg/kg/i.p.), a CB2 antagonist, but not GW6471 (1mg/kg/i.p.), a PPAR-alpha antagonist. Finally, PEA reduced the number of ear scratchings 48h after DNFB challenge and this effect was reversed by both CB2 and PPAR-alpha antagonists, suggesting the involvement of both receptors. PEA, by reducing the features of late stage CAD in mice, may be beneficial in this pathological condition. PMID- 27720682 TI - Updated mitochondrial phylogeny of Pteriomorph and Heterodont Bivalvia, including deep-sea chemosymbiotic Bathymodiolus mussels, vesicomyid clams and the thyasirid clam Conchocele cf. bisecta. AB - The mitochondrial genomes of bivalves have often been used for comparative genomics and for resolving phylogenetic relationships. More than 100 bivalve complete mitochondrial genomes have been sequenced to date. However, few mitochondrial genomes have been reported for deep-sea chemosymbiotic bivalves, which belong to the subclasses Pteriomorphia and Heterodonta. In the present study, we sequenced the mitochondrial genomes of eight deep-sea chemosymbiotic bivalve species: three species of Bathymodiolus mussels (B. japonicus, B. platifrons, and B. septemdierum), four species of vesicomyid clams (Abyssogena mariana, A. phaseoliformis, Isorropodon fossajaponicum, and Phreagena okutanii, all of which were formerly classified in the genus Calyptogena), and one species of thyasirid clam (Conchocele cf. bisecta). With a few exceptions, these mitochondrial genomes contained genes that are typical of metazoans: 13 protein coding genes, two rRNA genes, and 22 tRNA genes. The major non-coding region with a high A+T content of each genome, which contained tandem repeats and hairpins, was hypothesized to function as a control region. The phylogenetic trees of Pteriomorphia and Heterodonta were reconstructed based on the concatenated sequences of 14 shared genes. Bathymodiolus formed a monophyletic clade with asymbiotic Mytilidae mussels, the vesicomyid clams formed a monophyly that was sister to the Veneridae, and C. cf. bisecta branched basally in the Heterodonta. It is known that the gene orders of mitochondrial genomes vary among bivalves. To examine whether gene order variation exhibits phylogenetic signals, tree topologies based on the minimum number of gene rearrangements were reconstructed for two clades (superfamily Tellinoidea, which includes the Psammobiidae, Semelidae, Solecurtidae, and Tellinidae; and the clade comprising the Myidae, Mactridae, Arcticidae, Vesicomyidae, and Veneridae) with high statistical support in sequence-based phylogenies. The resulting tree topologies were almost identical to those of the sequence-based trees. Our present findings suggest that the evolution of bivalves could be precisely traced back through the analysis of mitochondrial genomes, and that such an analysis could contribute to understanding bivalve evolution and diversity. PMID- 27720683 TI - The role of face transplantation in the self-inflicted gunshot wound. AB - BACKGROUND: Facial self-inflicted gunshot wounds (SIGSWs) cause a devastating midfacial defect and pose a challenging problem to the reconstructive surgeon. Face transplantation (FT) has the potential for near-normal restoration in otherwise non-reconstructible defects. Two out of 7 FT recipients at Brigham and Women's Hospital (BWH) sustained SIGSWs. In this study, we illustrate the role of FT in the management of SIGSWs through an aesthetic, functional, and psychosocial examination of outcomes. METHODS: We performed a retrospective analysis of individuals with SIGSWs who were screened at BWH between 2008 and 2015. We then collected data of the injuries, modes of conventional reconstruction (CR), and deficits. For the FT recipients, we critically reviewed the psychosocial screening process and post-transplantation aesthetic, functional, and psychosocial outcomes. RESULTS: A total of six individuals post-SIGSWs were screened for FT. All of them had undergone CR, with five receiving loco-regional flaps and free tissue transfers, and one undergoing serial debridement and primary soft-tissue repair. Following CR, all suffered from residual functional and aesthetic deficits. Two underwent partial FT and one is currently undergoing FT screening. We describe the pre-transplant psychosocial screening process and the aesthetic, functional, and psychosocial outcomes of the SIGSW FT recipients. CONCLUSIONS: We examined the facial SIGSW injury, outcomes of CR, and the mechanism of FT to offer a potential solution to the shortcomings of CR. More importantly, we highlight the critical nature of the psychosocial component of the multidisciplinary evaluation given the history of mental illness and suicidal behavior in this subset of patients. PMID- 27720684 TI - Anti-inflammatory signaling actions of electrophilic nitro-arachidonic acid in vascular cells and astrocytes. AB - Nitrated derivatives of unsaturated fatty acids (nitro-fatty acids) are being formed and detected in human plasma, cell membranes and tissue, triggering signaling cascades via covalent and reversible post-translational modifications of nucleophilic amino acids in transcriptional regulatory proteins. Arachidonic acid (AA) represents a precursor of potent signaling molecules, i.e., prostaglandins and thromboxanes through enzymatic and non-enzymatic oxidative pathways. Arachidonic acid can be nitrated by reactive nitrogen species leading to the formation of nitro-arachidonic acid (NO2-AA). A critical issue is the influence of NO2-AA on prostaglandin endoperoxide H synthases, modulating inflammatory processes through redirection of AA metabolism and signaling. In this prospective article, we describe the key chemical and biochemical actions of NO2-AA in vascular and astrocytes. This includes the ability of NO2-AA to mediate unique redox signaling anti-inflammatory actions along with its therapeutic potential. PMID- 27720685 TI - Insight into the impact of two structural calcium ions on the properties of Pleurotus eryngii versatile ligninolytic peroxidase. AB - Two structural Ca2+ (proximal and distal) is known to be important for ligninolytic peroxidases. However, few studies toward impact of residues involved in two Ca2+ on properties of ligninolytic peroxidases have been done, especially the proximal one. In this study, mutants of nine residues involved in liganding two Ca2+ of Pleurotus eryngii versatile peroxidase (VP) were investigated. Most mutants almost completely lost activities, except the mutants of proximal Ca2+ - S170A and V192T. In comparison with WT (wild type), optimal pH values of S170A, S170D, and V192T shifted from pH 3.0 to pH 3.5. The order of thermal and pH stabilities of WT, V192T, S170A, and S170D is similar to that of their specific activities: WT > V192T > S170A > S170D. The CD (circular dichroism) results of WT and several mutants indicated that mutations had some effects on secondary structures. For the first time, it was observed that the thermostability of ligninolytic peroxidases is related with proximal Ca2+ too, and the mutant containing distal Ca2+ only was obtained. Our results clearly demonstrated that enzymatic activities, pH and thermal stabilities, Ca2+content, and secondary structures of VP have close relationship with the residues involved in two structural Ca2+. PMID- 27720686 TI - Role of pannexin 1 in Clostridium perfringens beta-toxin-caused cell death. AB - BACKGROUND: Beta-toxin produced by Clostridium perfringens is a key virulence factor of fatal hemorrhagic enterocolitis and enterotoxemia. This toxin belongs to a family of beta-pore-forming toxins (PFTs). We reported recently that the ATP gated P2X7 receptor interacts with beta-toxin. The ATP-release channel pannexin 1 (Panx1) is an important contributor to P2X7 receptor signaling. Hence, we investigated the involvement of Panx1 in beta-toxin-caused cell death. METHODS: We examined the effect of Panx1 in beta-toxin-induced cell death utilizing selective antagonists, knockdown of Panx1, and binding using dot-blot analysis. Localization of Panx1 and the P2X7 receptor after toxin treatment was determined by immunofluorescence staining. RESULTS: Selective Panx1 antagonists (carbenoxolone [CBX], probenecid, and Panx1 inhibitory peptide) prevented beta toxin-caused cell death in THP-1 cells. CBX did not block the binding of the toxin to cells. Small interfering knockdown of Panx1 blocked beta-toxin-mediated cell death through inhibiting the oligomer formation of the toxin. Beta-toxin triggered a transient ATP release from THP-1 cells, but this early ATP release was blocked by CBX. ATP scavengers (apyrase and hexokinase) inhibited beta-toxin induced cytotoxicity. Furthermore, co-administration of ATP with beta-toxin enhanced the binding and cytotoxicity of the toxin. CONCLUSIONS: Based on our results, Panx1 activation is achieved through the interaction of beta-toxin with the P2X7 receptor. Then, ATP released by the Panx1 channel opening promotes oligomer formation of the toxin, leading to cell death. GENERAL SIGNIFICANCE: Pannexin 1 is a novel candidate therapeutic target for beta-toxin-mediated disease. PMID- 27720687 TI - Putting numbers on the End TB Strategy-an impossible dream?

PMID- 27720690 TI - Aluminum trichloride induces bone impairment through TGF-beta1/Smad signaling pathway. AB - Aluminum (Al) is recognized worldwide as serious inorganic contaminants. Exposure to Al is associated with low BMD and an increased risk of osteoporosis. However, the precise molecular mechanisms remains unclear. Thus, in this study, rats were orally exposed to 0 (control group, CG) and 0.4g/L AlCl3 (AlCl3 treated group, AG) in drinking water for 120days; osteoblasts were treated with AlCl3 (0.12mg/mL) and/or TGF-beta1 (4.5ng/mL) for 24h. We found that AlCl3 decreased the BMD, damaged femoral ultrastructure, decreased the activities of GSH-Px and SOD, and increased the levels of ROS and MDA in bone, decreased the activity of B ALP and content of PINP, and increased the activity of TRACP-5b and content of NTX-I in serum, decreased mRNA expressions of TGF-beta1, TbetaRI, TbetaRII and Smad4, protein expressions of TGF-beta1, p-Smad2/3 and Smad2/3/4 complex, and increased Smad7 mRNA expression in bone and in osteoblasts. Moreover, we found exogenous TGF-beta1 application reversed the inhibitory effect of AlCl3 on osteoblasts activity by activating the TGF-beta1/Smad signaling pathway and increasing the mRNA expressions of ALP and Col I in osteoblasts. These results demonstrate that AlCl3 induces bone impairment through inactivation of TGF beta1/Smad signaling pathway. PMID- 27720688 TI - Feasibility of achieving the 2025 WHO global tuberculosis targets in South Africa, China, and India: a combined analysis of 11 mathematical models. AB - BACKGROUND: The post-2015 End TB Strategy proposes targets of 50% reduction in tuberculosis incidence and 75% reduction in mortality from tuberculosis by 2025. We aimed to assess whether these targets are feasible in three high-burden countries with contrasting epidemiology and previous programmatic achievements. METHODS: 11 independently developed mathematical models of tuberculosis transmission projected the epidemiological impact of currently available tuberculosis interventions for prevention, diagnosis, and treatment in China, India, and South Africa. Models were calibrated with data on tuberculosis incidence and mortality in 2012. Representatives from national tuberculosis programmes and the advocacy community provided distinct country-specific intervention scenarios, which included screening for symptoms, active case finding, and preventive therapy. FINDINGS: Aggressive scale-up of any single intervention scenario could not achieve the post-2015 End TB Strategy targets in any country. However, the models projected that, in the South Africa national tuberculosis programme scenario, a combination of continuous isoniazid preventive therapy for individuals on antiretroviral therapy, expanded facility-based screening for symptoms of tuberculosis at health centres, and improved tuberculosis care could achieve a 55% reduction in incidence (range 31-62%) and a 72% reduction in mortality (range 64-82%) compared with 2015 levels. For India, and particularly for China, full scale-up of all interventions in tuberculosis programme performance fell short of the 2025 targets, despite preventing a cumulative 3.4 million cases. The advocacy scenarios illustrated the high impact of detecting and treating latent tuberculosis. INTERPRETATION: Major reductions in tuberculosis burden seem possible with current interventions. However, additional interventions, adapted to country-specific tuberculosis epidemiology and health systems, are needed to reach the post-2015 End TB Strategy targets at country level.

PMID- 27720692 TI - Modelling late stool frequency and rectal pain after radical radiotherapy in prostate cancer patients: Results from a large pooled population. AB - AIM: To investigate late gastrointestinal toxicity in a large pooled population of prostate cancer patients treated with radical radiotherapy. Normal tissue complication probability models were developed for late stool frequency and late rectal pain. METHODS AND MATERIALS: Population included 1336 patients, 3-year minimum follow-up, treated with 66-80Gy. Toxicity was scored with LENT-SOMA scale. Two toxicity endpoints were considered: grade ?2 rectal pain and mean grade (average score during follow-up) in stool frequency >1. DVHs of anorectum were reduced to equivalent uniform dose (EUD). The best-value of the volume parameter n was determined through numerical optimization. Association between EUD/clinical factors and the endpoints was investigated by logistic analyses. Likelihood, Brier-score and calibration were used to evaluate models. External calibration was also carried out. RESULTS: 4% of patients (45/1122) reported mean stool frequency grade >1; grade ?2 rectal pain was present in the TROG 03.04 RADAR population only (21/677, 3.1%): for this endpoint, the analysis was limited to this population. Analysis of DVHs highlighted the importance of mid-range doses (30-50Gy) for both endpoints. EUDs calculated with n=1 (OR=1.04) and n=0.35 (OR=1.06) were the most suitable dosimetric descriptors for stool frequency and rectal pain respectively. The final models included EUD and cardiovascular diseases (OR=1.78) for stool frequency and EUD and presence of acute gastrointestinal toxicity (OR=4.2) for rectal pain. CONCLUSION: Best predictors of stool frequency and rectal pain are consistent with findings previously reported for late faecal incontinence, indicating an important role in optimization of mid-range dose region to minimize these symptoms highly impacting the quality-of-life of long surviving patients. PMID- 27720694 TI - The power of capturing and using information at the point of care. AB - Historically, the process of scientific discovery and the process of clinical delivery have been poorly integrated. As a result of the Decade of Health Information Technology (2004-2014), many of the former barriers to capturing, processing, and retrieving medical information at the point of care have been surmounted. This change has the potential to both transform how new medical discoveries are made and how evidence-based medicine is put into practice. To illustrate the impact of this ongoing change, several examples are provided of institutions which have innovatively used information at the point of care. PMID- 27720693 TI - Ethnic and sex-specific cut-off values for adult obesity in the Suriname Health Study. AB - BACKGROUND: Sex-specific body mass index (BMI) and waist circumference (WC) cut off values have been validated for a limited number of ethnic groups. We aimed to derive these cut-off values for Amerindians, Creoles, Hindustani, Javanese, Maroons and Mixed living in Suriname. METHODS: Data from individuals aged 20-65, in the Suriname Health Study was used to derive optimal cut-off values for BMI and WC for the prediction of hypertension (n=4910) and cardio-metabolic risk (n=2924). Results from the analysis with Receiver Operating Curves were calculated and compared these with recommended values. RESULTS: The area under the ROC curve was consistently higher for WC compared to BMI among Creoles, Hindustani, Maroons and Mixed. The BMI cut-off values ranged from 24.8kg/m2 for Creole men and 26.9kg/m2 for Maroon women to 28.4kg/m2 and 30.2kg/m2 for Amerindian men and women, respectively. The WC cut-off values ranged from 80.7cm for Maroon men, 86.7cm for Javanese women to 90.8cm for Hindustani men and 95.7cm for Amerindian women. Optimal BMI cut-off values approximated Asian cut-off values from the World Health Organization whilst those of WC for men approximated and for women exceeded cut-off values from the International Diabetes Federation. CONCLUSION: In most ethnic groups, we found better discriminatory power for WC compared to BMI in the relation with cardiovascular risk factors. The estimated BMI and WC cut-off values differed between ethnic groups. Further studies are needed to identify cut-off values related to the future risk of cardiovascular disease and mortality. PMID- 27720696 TI - Transcriptome analysis of grey mullet (Mugil cephalus) after challenge with Lactococcus garvieae. AB - Grey mullet (Mugil cephalus) is an economically important fish species in Taiwan mariculture industry. Moreover, grey mullet are common hosts of a bacterial infection by Lactococcus garvieae. However, until now the information related to the immune system of grey mullet is unclear. Therefore, to understand the molecular basis underlying the host immune response to L. garvieae infection, Illumina HiSeqTM 2000 was used to analyse the head kidney and spleen transcriptome of infected grey mullet. De novo assembly of paired-end reads yielded 55,203 unigenes. Comparative analysis of the expression profiles between bacterial challenge fish and control fish identified a total of 7192 from head kidney and 7280 in spleen differentially expressed genes (P < 0.05), including 4211 upregulated genes and 2981 downregulated genes in head kidney, while in spleen 3598 genes were upregulated and 3682 downregulated. A significant enrichment analysis of these differentially expressed genes (DEG) in spleen and head kidney revealed major immune-related pathways, including complement and coagulation cascades, Toll-like receptor signalling, and antigen processing and presentation. Moreover, selected DEGs were validated using qPCR. Altogether, the results obtained on immune-related genes may allow for a better understanding of immunity in grey mullet to Lactococcus garvieae, carrying out detailed functional analysis of these genes and developing strategies for efficient immune protection against infections in grey mullet. PMID- 27720695 TI - CD94 of tongue sole Cynoglossus semilaevis binds a wide arrange of bacteria and possesses antibacterial activity. AB - In this study, we examined the expression patterns and the functions of the tongue sole Cynoglossus semilaevis CD94, CsCD94. CsCD94 is composed of 209 amino acid residues and shares 43.0-50.2% overall identities with known teleost CD94 sequence. CsCD94 has a C-type lectin-like domain. Expression of CsCD94 occurred in multiple tissues and was upregulated during bacterial infection. Recombinant CsCD94 (rCsCD94) exhibited apparent binding and agglutinating activities against both Gram-positive and Gram-negative bacteria in a Ca2+-dependent manner. Treatment of bacteria with rCsCD94 enhanced phagocytosis of the bacteria by peripheral blood leukocytes. Furthermore, incubation of rCsCD94 with bacteria reduced the survival of the bacteria in vitro. Taken together, these results indicate that rCsCD94 is a key factor in the bactericidal and phagocytic effects of tongue sole, and reveal for the first time an essential role of fish CD94 in antibacterial immunity, thereby adding insight into the function of CD94.

PMID- 27720689 TI - Cost-effectiveness and resource implications of aggressive action on tuberculosis in China, India, and South Africa: a combined analysis of nine models. AB - BACKGROUND: The post-2015 End TB Strategy sets global targets of reducing tuberculosis incidence by 50% and mortality by 75% by 2025. We aimed to assess resource requirements and cost-effectiveness of strategies to achieve these targets in China, India, and South Africa. METHODS: We examined intervention scenarios developed in consultation with country stakeholders, which scaled up existing interventions to high but feasible coverage by 2025. Nine independent modelling groups collaborated to estimate policy outcomes, and we estimated the cost of each scenario by synthesising service use estimates, empirical cost data, and expert opinion on implementation strategies. We estimated health effects (ie, disability-adjusted life-years averted) and resource implications for 2016-35, including patient-incurred costs. To assess resource requirements and cost effectiveness, we compared scenarios with a base case representing continued current practice. FINDINGS: Incremental tuberculosis service costs differed by scenario and country, and in some cases they more than doubled existing funding needs. In general, expansion of tuberculosis services substantially reduced patient-incurred costs and, in India and China, produced net cost savings for most interventions under a societal perspective. In all three countries, expansion of access to care produced substantial health gains. Compared with current practice and conventional cost-effectiveness thresholds, most intervention approaches seemed highly cost-effective. INTERPRETATION: Expansion of tuberculosis services seems cost-effective for high-burden countries and could generate substantial health and economic benefits for patients, although substantial new funding would be required. Further work to determine the optimal intervention mix for each country is necessary. FUNDING: Bill & Melinda Gates Foundation.

PMID- 27720699 TI - A 15-year experience of two hundred and twenty five consecutive right hepatectomies. AB - BACKGROUND: In case of liver tumor, surgical resection is the therapeutic gold standard to increase patient survival. Among liver resections, right hepatectomy (RH) is defined as a major hepatectomy. The first aim of this study was to analyze the overall morbidity and mortality of patients undergoing RH, the second aim was to assess changes in both patients characteristic and surgical parameters and mortality rates in a single center institution. MATERIALS: From 2001 to December 2015, 225 RH were performed in our center. We analyzed two time period: 2001-2007 and 2008-2015. RESULTS: Ninety days post operative mortality was observed in 9 cases (4%) for the overall cohort. We observed a difference between the two groups in the use of Pringle Maneuver (p<0,001). This result is consistent in each major surgical indication: HCC (p=0,001), CLM (p=0,015) and BT (p=0,015). The estimated blood losses improved (p=0,028), particularly for the HCC cases (p=0,024). No difference was observed in terms of number of transfusions received between the two groups. Reduced length of stay was observed in the second group (p<0,001), more markedly for CLM cases (p=0,001). CONCLUSION: To further improve the outcomes of RH, it is important to performed this major hepatectomy in hepatobiliary centers with an overall liver resection experience of at least few hundred cases. PMID- 27720700 TI - Manometric evaluation of anorectal function in patients treated with neoadjuvant chemoradiotherapy and total mesorectal excision for rectal cancer. AB - BACKGROUND: An altered anorectal function is reported after chemoradiotherapy (CRT) and surgery for rectal cancer. AIM: The aim of this study was to clarify the relative contribution of neoadjuvant chemoradiation and surgical resection on the impairment of anorectal function as evaluated by anorectal manometry. METHODS: Thirty-nine patients with rectal cancer, who underwent neoadjuvant CRT and laparoscopic rectal resection, were evaluated with the Pescatori Faecal Incontinence score, and with anorectal manometry: before neoadjuvant therapy (T0), after neoadjuvant therapy and before surgery (T1), 12 months after stoma closure (T2). RESULTS: Resting and/or maximum squeeze pressure and/or volume thresholds for urgency were below the normal values in 12 (30%) patients at baseline. After CRT the mean resting pressure significantly decreased (p=0.007). Surgery determined a significantly decrease of the resting pressure (p=0.001), of the maximum squeeze pressure (p=0.001) and of the volume threshold for urgency (p=0.001). Impairment of continence was reported by 5, 11 and 18 patients at T0, T1 and T2, with a mean incontinence score of 3, 3.8 and 3.9 respectively. CONCLUSIONS: CRT is detrimental to the function of the internal anal sphincter. Rectal resection significantly affects both internal and external anal sphincter function and the maximum tolerated volume of the neo-rectum, particularly in patients with low rectal cancer, significantly impairing anal continence. PMID- 27720701 TI - Detailed prospective peer review in a community radiation oncology clinic. AB - PURPOSE: In 2012, we instituted detailed prospective peer review of new cases. We present the outcomes of peer review on patient management and time required for peer review. METHODS AND MATERIALS: Peer review rounds were held 3 to 4 days weekly and required 2 physicians to review pertinent information from the electronic medical record and treatment planning system. Eight aspects were reviewed for each case: 1) workup and staging; 2) treatment intent and prescription; 3) position, immobilization, and simulation; 4) motion assessment and management; 5) target contours; 6) normal tissue contours; 7) target dosimetry; and 8) normal tissue dosimetry. Cases were marked as, "Meets standard of care," "Variation," or "Major deviation." Changes in treatment plan were noted. As our process evolved, we recorded the time spent reviewing each case. RESULTS: From 2012 to 2014, we collected peer review data on 442 of 465 (95%) radiation therapy patients treated in our hospital-based clinic. Overall, 91 (20.6%) of the cases were marked as having a variation, and 3 (0.7%) as major deviation. Forty-two (9.5%) of the cases were altered after peer review. An overall peer review score of "Variation" or "Major deviation" was highly associated with a change in treatment plan (P < .01). Changes in target contours were recommended in 10% of cases. Gastrointestinal cases were significantly associated with a change in treatment plan after peer review. Indicators on position, immobilization, simulation, target contours, target dosimetry, motion management, normal tissue contours, and normal tissue dosimetry were significantly associated with a change in treatment plan. The mean time spent on each case was 7 minutes. CONCLUSIONS: Prospective peer review is feasible in a community radiation oncology practice. Our process led to changes in 9.5% of cases. Peer review should focus on technical factors such as target contours and dosimetry. Peer review required 7 minutes per case. PMID- 27720702 TI - Preoperative short-course radiation therapy for rectal cancer provides excellent disease control and toxicity: Results from a single US institution. AB - PURPOSE: Preoperative short-course radiation therapy (SCRT) has rarely been used for rectal cancer in the United States, although 2 randomized phase 3 trials demonstrate equivalence to conventional chemoradiation (CRT), and recent updates to national guidelines include this regimen as a treatment option. We sought to evaluate the efficacy and safety of preoperative SCRT followed by immediate surgery within 1 week to treat rectal cancer in the US setting. METHODS AND MATERIALS: All patients treated with preoperative SCRT (4 Gy * 5 fractions for total 20 Gy) followed by planned surgery within 1 week at our institution were retrospectively evaluated. Censored cases with >=2 years of follow-up were included along with any disease failure or death. Patients with cM1 disease were excluded. Patients with yp stage II/III disease typically received adjuvant chemotherapy from the 1990s onwards. The primary outcomes were actuarial (Kaplan Meier) 5-year locoregional control (LC), disease-free survival (DFS), and overall survival (OS) as well as late severe (greater than or equal to grade 3) toxicity. RESULTS: Our analysis included 202 consecutive patients with clinical stage I-III disease treated from 1977 through 2011. Median follow-up was 6.5 years (range, 2 29.2). Five-year disease outcomes were 95.9% +/- 1.5% for LC, 76.4% +/- 3.1% for DFS, and 84.6% +/- 2.6% for OS. For patients with locally advanced rectal cancer (cT3-4 and/or cN+), 5-year LC, DFS, and OS were 95.1% +/- 2.1%, 73.3% +/- 4.3%, and 80.6% +/- 3.7%, respectively. The late severe toxicity rate was 11.4%. CONCLUSIONS: SCRT followed by immediate surgery is a safe and effective treatment for patients with rectal cancer in the United States. Though SCRT has not been widely adopted, recent updates to the national guidelines for rectal cancer as well as financial pressures to reduce healthcare costs may lead to increased utilization of this treatment regimen in the future. PMID- 27720703 TI - Margin of error for a frameless image guided radiosurgery system: Direct confirmation based on posttreatment MRI scans. AB - PURPOSE: To report on radiosurgery delivery positioning accuracy in the treatment of tremor patients with frameless image guided radiosurgery using the linear accelerator (LINAC) based ExacTrac system and to describe quality assurance (QA) procedures used. METHODS AND MATERIALS: Between 2010 and 2015, 20 patients underwent radiosurgical thalamotomy targeting the ventral intermediate nucleus for the treatment of severe tremor. The median prescription dose was 140 Gy (range, 120-145 Gy) in a single fraction. The median maximum dose was 156 Gy (range, 136-162 Gy). All treatment planning was performed with the iPlan system using a 4-mm circular cone with multiple arcs. Before each treatment, QA procedures were performed, including the imaging system. As a result of the extremely high dose delivered in a single fraction, a well-defined circular mark developed on the posttreatment magnetic resonance imaging (MRI). Eight of these 20 patients were selected to evaluate treatment localization errors because their circular marks were available in posttreatment MRI. In this study, the localization error is defined as the distance between the center of the intended target and the center of the posttreatment mark. RESULTS: The mean error of distance was found to be 1.1 mm (range, 0.4-1.5 mm). The mean errors for the left right, anteroposterior, and superoinferior directions are 0.5 mm, 0.6 mm, and 0.7 mm, respectively. CONCLUSIONS: The result reported in this study includes all tremor patients treated at our institution when their posttreatment MRI data were available for study. It represents a direct confirmation of target positioning accuracy in radiosurgery with a LINAC-based frameless system and its limitations. This level of accuracy is only achievable with an appropriate QA program in place for a LINAC-based frameless radiosurgery system.

PMID- 27720706 TI - The effect of parental rejection on the emotional eating behaviour of youngsters: A laboratory-based study. AB - Results from survey studies demonstrate a relationship between parental rejection and self-reported emotional eating of youngsters. The aim of the current study was to build on this research by examining the relationship between parental rejection and actual emotional eating, using an experimental laboratory paradigm. Participants were 46 youngsters between the ages of 10 and 17 years old. Participants first completed online questionnaires at home, measuring parental rejection and emotional eating style. At the laboratory, participants were randomly assigned to a neutral condition or negative mood condition, followed by a multi-item snack buffet. The interaction effect maternal rejection * condition on energy intake from savoury food was significant. More maternal rejection predicted more energy intake from savoury food in the negative mood condition, but not in the neutral condition. The results highlight the importance of assessing, and if mandatory, improving the emotional bond between parent and child in the prevention and intervention of emotional eating. PMID- 27720707 TI - Perspectives on learning to cook and public support for cooking education policies in the United States: A mixed methods study. AB - Declines in cooking skills in the United States may contribute to poor diet quality and high obesity rates. Little is known about how Americans learn to cook or their support for cooking education policies. The objective of this study was to examine how Americans learn to cook, attributions of responsibility for teaching children how to cook, and public support for policies to teach cooking skills. We used a concurrent, triangulation mixed-methods design that combined qualitative focus group data (from 7 focus groups in Baltimore, MD (N = 53)) with quantitative survey data from a nationally representative, web-based survey (N = 1112). We analyzed focus group data (using grounded theory) and survey data (using multivariable logistic regression). We find that relatively few Americans learn to cook from formal instruction in school or community cooking classes; rather, they primarily learn from their parents and/or by teaching themselves using cookbooks, recipe websites or by watching cooking shows on television. While almost all Americans hold parents and other family members responsible for teaching children how to cook, a broad majority of the public supports requiring cooking skills to be taught in schools either through existing health education (64%) or through dedicated home economics courses (67%). Slightly less than half of all Americans (45%) support increasing funding for cooking instruction for participants in the Supplemental Nutrition Assistance Program (SNAP). Broad public support for teaching cooking skills in schools suggests that schools are one promising avenue for policy action. However, school-based strategies should be complemented with alternatives that facilitate self-learning. More research is needed to identify effective means of teaching and disseminating the key cooking skills and knowledge that support healthy eating. PMID- 27720709 TI - Neutral point testing of color vision in the domestic cat. AB - Despite extensive study, the basic nature of feline spectral sensitivity is still unresolved. Most electrophysiological studies have demonstrated two photopic receptors within the cat's retina, one most sensitive to longer wavelengths near 560 nm and the other most sensitive to shorter wavelengths near 460 nm, providing the neuroretinal basis for dichromatic vision. A few studies, however, have detected a third photopic receptor most sensitive to medium wavelengths between 500 and 520 nm, overlapping in spectrally sensitivity with the feline scotopic receptor, that potentially could allow trichromatic vision. Indeed, one behavioral study has demonstrated trichromatic vision in cats, but a flaw within its experimental design raises the possibility that achromatic intensity cues might have allowed the accurate identification of medium wavelength targets. This study tested for a spectral neutral point in the domestic cat using a two-choice discrimination task. The positive targets were created using monochromatic light from various single wavelength light emitting diodes (LEDs) combined with a white light of variable intensity, while the negative targets were created using white light of variable intensity. Trials were performed with varying intensities of positive and negative targets, from brighter positive targets to brighter negative targets, to eliminate achromatic intensity cues. Two cats with prior experience with two-choice discrimination tasks, one male and one female, successfully discriminated monochromatic light from 456 nm to 497 nm and from 510 nm to 524 nm, but both failed to discriminate monochromatic light at 505 nm over multiple trials. These results provide strong evidence that cats are dichromatic with a neutral point near 505 nm. This neutral point is nearly identical to the neutral point of the human deuteuranope, making feline vision a more accurate a model for red-green colorblind individuals than normal trichromats. PMID- 27720708 TI - Invariant natural killer T cells play dual roles in the development of experimental autoimmune uveoretinitis. AB - Experimental autoimmune uveoretinitis (EAU) represents an experimental model for human endogenous uveitis, which is caused by Th1/Th17 cell-mediated inflammation. Natural killer T (NKT) cells recognize lipid antigens and produce large amounts of cytokines upon activation. To examine the role of NKT cells in the development of uveitis, EAU was elicited by immunization with a peptide from the human interphotoreceptor retinoid-binding protein (hIRBP1-20) in complete Freund's adjuvant and histopathology scores were evaluated in C57BL/6 (WT) and NKT cell deficient mice. NKT cell-deficient mice developed more severe EAU pathology than WT mice. When WT mice were treated with ligands of the invariant subset of NKT cells (alpha-GalCer or RCAI-56), EAU was ameliorated in mice treated with RCAI-56 but not alpha-GalCer. IRBP-specific Th1/Th17 cytokines were reduced in RCAI-56 treated compared with vehicle-treated mice. Although the numbers of IRBP-specific T cells detected by hIRBP3-13/I-Ab tetramers in the spleen and the draining lymph node were the same for vehicle and RCAI-56 treatment groups, RORgammat expression by tetramer-positive cells in RCAI-56-treated mice was lower than in control mice. Moreover, the eyes of RCAI-56-treated mice contained fewer IRBP-specific T cells compared with control mice. These results suggest that invariant NKT (iNKT) cells suppress the induction of Th17 cells and infiltration of IRBP-specific T cells into the eyes, thereby reducing ocular inflammation. However, in sharp contrast to the ameliorating effects of iNKT cell activation during the initiation phase of EAU, iNKT cell activation during the effector phase exacerbated disease pathology. Thus, we conclude that iNKT cells exhibit dual roles in the development of EAU. PMID- 27720710 TI - The Nurse's Role in the Promotion of Safe Sleep for Infants. PMID- 27720711 TI - Posterior Reversible Encephalopathy Syndrome: A Comparative Study of Pediatric Versus Adult Patients. AB - BACKGROUND: Posterior reversible encephalopathy syndrome (PRES) is an acute neurotoxic syndrome that, although characteristically reversible, can result in long-term disability. Our aim was to identify the clinical and radiological factors that are unique to children with PRES compared with adults with the syndrome in a single center. METHODS: We retrospectively reviewed the clinical and radiological records of all patients with PRES admitted at a tertiary care medical center from 2007 to 2014. All patients who met the clinical and radiological criteria for PRES were dichotomized into children (less than 18 years) and adults (18 years or older) based on their age groups, and comparison of their baseline variables, clinical, laboratory, and imaging features was performed. RESULTS: During this study period, 19 pediatric patients and 100 adult patients with PRES were identified. On univariate analysis, factors significantly associated with pediatric patients with the syndrome were multiorgan failure (84.2% vs 50%, P = 0.006), temporal lobe involvement (63.3% vs 39%, P = 0.04), restricted diffusion (42.1% vs 18%, P = 0.02), and less likelihood of cerebellar involvement (21.1% vs 57%, P = 0.004). On bivariate logistic regression analysis, all these factors remained significantly associated with pediatric PRES; multiorgan failure (odds ratio: 5.80, 95% confidence interval: 1.45 to 29.41, P = 0.03), temporal lobe involvement (odds ratio: 5.08, 95% confidence interval: 1.17 to 22.17, P = 0.03), restricted diffusion (odds ratio: 2.48, 95% confidence interval: 1.61 to 10.10, P = 0.02), and less likely to have cerebellar involvement (odds ratio: 0.08, 95% confidence interval: 0.002 to 0.39, P = 0.002). CONCLUSIONS: Factors unique to PRES in children compared with adults include a greater propensity with multi-organ failure, involvement of the temporal lobe, and restricted diffusion on imaging. PMID- 27720712 TI - Relapsing Acute Axonal Neuropathy in Hereditary Fructose Intolerance. AB - BACKGROUND: A severe neurological abnormality has not been previously described in individuals with hereditary fructose intolerance, which typically presents early in childhood with severe metabolic acidosis and hypoglycemia. PATIENT DESCRIPTION: We describe a boy who by age five years had required multiple admissions to the pediatric intensive care unit for an aggressive and atypical, relapsing and remitting neuropathy with features of acute motor axonal neuropathy (AMAN). It was later discovered that he also had undiagnosed hereditary fructose intolerance, and the severity and frequency of his neurological episodes diminished following an exclusion diet. His asymptomatic younger brother was diagnosed with hereditary fructose intolerance on screening. He is on a fructose free diet and has not developed neurological symptoms. CONCLUSIONS: Ongoing low level exposure to fructose prior to diagnosis may have contributed to our patient's neurological dysfunction. Early diagnosis and treatment may prevent neurological complications of hereditary fructose intolerance. PMID- 27720713 TI - Up-regulation of GTPBP4 in colorectal carcinoma is responsible for tumor metastasis. AB - GTP binding protein 4(GTPBP4), a member of GTP-binding protein family, was previously characterized as a tumor suppressor that regulates and requires merlin to suppress cell proliferation. However, the role of GTPBP4 in the metastasis of colorectal carcinoma (CRC) remains unelucidated. Here, we observed that GTPBP4 was detected at higher levels in CRC metastatic tissues than that in the primary tumor tissues. Notably, up-regulation of GTPBP4 was closely correlated with tumor metastasis in CRCs. Kaplan-Meier and multivariate Cox regression analysis indicated GTPBP4 as an independent prognostic factor for CRC patients (hazard ratio = 2.693, 95% confident interval: 1.193-6.083, p = 0.017). Functional studies established that knockdown of GTPBP4 impeded, whereas ectopic expression of GTPBP4 enhanced cell motility and tumor metastasis in CRC cells. Interestingly, mechanistic investigations suggested that GTPBP4 may disorganize actin cytoskeleton through repressing RhoA signaling. Taken together, our research uncovered that GTPBP4 promotes CRC metastasis by disrupting actin cytoskeleton, which is mediated by the reduced RhoA activity. Strategies targeting GTPBP4 will be promising for CRC patients with metastases. PMID- 27720714 TI - Visual assessment of parasitic burden in infected macrophage by plasmonic detection of leishmania specific marker RNA. AB - Visceral leishmaniasis is a neglected tropical disease and may prove fatal if not diagnosed and treated early. The amastigotes of Leishmania donovani nest in the macrophage of human host and thus, determination of parasitic burden in the infected macrophages has been the most crucial step in diagnosis, dose determination and medical management of relapse cases of this fatal disease. Microscopic count following Giemsa staining and other morphological analysis are the classical ways vastly used in the resource stringent endemic areas. The current method introduced a high throughput, rapid, cheap, non-gel, non-PCR and nonculture based visual detection platform employing salt triggered aggregation of gold nanoparticle in presence of extracted total RNA from infected macrophages and leishmania specific oligo-nucleotide probe to determine the parasite burden in macrophages. Amastigote's small subunit ribosomal RNA (SSU rRNA, PMID 1565128) was used as the leishmania specific marker and its abundance in the total RNA extracts of infected macrophages were determined by this visual colorimetric assay. PMID- 27720715 TI - miR-216b suppresses breast cancer growth and metastasis by targeting SDCBP. AB - Breast cancer is the most deadly cancer among women and the second leading cause of cancer death worldwide. Treatment effectiveness is complicated with tumor invasiveness/drug resistance. To tailor treatments more effectively to individual patients, it is important to define tumor growth and metastasis at molecular levels. SDCBP is highly overexpressed and associated with a strikingly poor prognosis in breast cancer. However the post transcriptional regulation of SDCBP overexpression remains to be an unexplored area. Our study reveals that miR-216b directly regulates SDCBP expression by binding to its 3'UTR region. miR-216b is a tumor suppressive miRNA and it is underexpressed during metastatic breast cancer. Consequently, overexpression of miR-216b resulted in decreased proliferation, migration and invasion in BC cell lines by modulating the expression of SDCBP. Inhibition of miR-216b divergent the tumor suppressive role by inducing the growth proliferation, migration and invasion in vitro. There is therefore a negative correlation between the expression of miR-216b and its target gene SDCBP in the BC tissue samples as well as cell lines. Simultaneous expression of miR 216b and SDCBP rescued the growth, migration and invasion effect suggesting that tumor suppressive action of miR-216b may be directly mediated by SDCBP. In summary, the study identifies miR-216b as a regulator of SDCBP expression in breast cancer which can potentially be targeted for developing newer therapies for the effective treatment of this killer disease. PMID- 27720717 TI - A variety of human monoclonal antibodies against epidermal growth factor receptor isolated from a phage antibody library. AB - When the technology for constructing human antibody (Ab) libraries using a phage display system was developed, many researchers in Ab-related fields anticipated that it would be widely applied to the development of pharmaceutical drugs against various diseases, including cancers. However, successful examples of such applications are very limited. Moreover, researchers who utilize phage-display technology now show divergent ways of thinking about phage Ab libraries. For example, there is debate about what should be the source of VH and VL genes for the construction of libraries to cover the whole repertoire of Abs present in the human body. In the immune system, the introduction of mutations into V genes followed by selection based on binding activity, termed Ab maturation, is required for the production of Abs exhibiting high affinity to the antigen (Ag). Therefore, introduction of mutations and selection are required for isolation of Abs with high affinity after isolation of clones from phage Ab libraries. We constructed a large human Ab library termed AIMS, developed a screening method termed ICOS, and succeeded in isolating many human monoclonal Abs (mAbs) that specifically and strongly bind to various tumor-associated Ags. Eight anti-EGFR mAbs were included, which we characterized. These mAbs showed various different activities against EGFR-expressing cancer cells. In this paper, we describe these data and discuss the possibility and necessity that the mAbs isolated from the AIMS library might be developed as therapeutic drugs against cancers without introduction of mutations. PMID- 27720716 TI - Possible pathogenic engagement of soluble Semaphorin 4D produced by gammadeltaT cells in medication-related osteonecrosis of the jaw (MRONJ). AB - Prior consensus held that medication-related osteonecrosis of the jaw (MRONJ) lesion was composed of necrotic bone; however, more recent studies have identified inflammatory infiltrates in the lesion. Herein, we report that remarkably elevated infiltrating gammadeltaT cells (90% of lymphocytes) express Semaphorin 4D (Sema4D) in human patient with MRONJ lesion, whereas gammadeltaT cells only account for 2-5% of lymphocytes in blood. Importantly, Sema4D is implicated in the pathogenesis of T cell-mediated inflammatory diseases, such as rheumatoid arthritis and multiple sclerosis. Indeed, in a mouse model of MRONJ, an elevated number of gammadeltaT, but not alphabetaT, cells infiltrating in the MRONJ-like lesion was observed. Both elevated soluble Sema4D (sSema4D) production accompanied by pro-inflammatory cytokines, including TNF-alpha IFN-gamma and IL 1beta, and Sema4D-expressing gammadeltaT cells were detected in mouse MRONJ-like lesion. Activated gammadeltaT cells produced sSema4D in vitro, which could promote TNF-alpha production from macrophages. Meanwhile, gammadeltaT cell-KO mice were resistant to the induction of MRONJ and, hence, showed no elevation of local productions of Sema4D and TNF-alpha. Finally, systemic administration of anti-Sema4D neutralizing mAb suppressed the onset of MRONJ in wild-type mice in conjunction with diminished level of TNF-alpha. These results suggested a critical pathogenic engagement of Sema4D produced by gammadeltaT cells in the development of MRONJ. PMID- 27720718 TI - Therapeutic efficacy of an anti-PD-L1 antibody based immunocytokine in a metastatic mouse model of colorectal cancer. AB - Immunocytokines (antibody-cytokine fusions) have been proved to be a promising class of therapeutic agents for tumors. Anti-PD-L1 antibodies or IL-2 have been used to treat a variety of cancers. Here, in order to remove T cell inhibition and increasing the IL-2 concentration in the tumor microenvironment, we engineered a novel anti-PD-L1 antibody based immunocytokine by fusing hIL-2 to the C-Term of atezolizumab, denoted as BIPI. Our results revealed that BIPI was effective in stimulating T cell activation in vitro and could selectively localize to the tumor. Furthermore, tumor regression and prolonged survival were also observed in the metastatic colorectal cancer mouse model. The obviously longer survival mice in BIPI treatment group turned out depending on the function of CD8+ T cells. The IFN- secreted from CD8+ T cells in the spleen also contributed to the better tumor inhibition profile in BIPI treatment group than in anti-PD-L1 or IL-2 treatment alone. Taken together, our data evidenced the enhanced antitumor potency of BIPI, suggesting its potential use for cancers with a low response to the anti-PD-L1 or IL-2 treatment. PMID- 27720719 TI - History of antimicrobial drug discovery: Major classes and health impact. AB - The introduction of antibiotics into clinical practice revolutionized the treatment and management of infectious diseases. Before the introduction of antibiotics, these diseases were the leading cause of morbidity and mortality in human populations. This review presents a brief history of discovery of the main antimicrobial classes (arsphenamines, beta-lactams, sulphonamides, polypeptides, aminoglycosides, tetracyclines, amphenicols, lipopeptides, macrolides, oxazolidinones, glycopeptides, streptogramins, ansamycins, quinolones, and lincosamides) that have changed the landscape of contemporary medicine. Given within a historical timeline context, the review discusses how the introduction of certain antimicrobial classes affected the morbidity and mortality rates due to bacterial infectious diseases in human populations. Problems of resistance to antibiotics of different classes are also extensively discussed. PMID- 27720720 TI - Comparative Evaluation of Condylar Volume Between Patients With Unilateral Condylar Hyperplasia and Class III Dentofacial Deformity. AB - PURPOSE: To compare the condylar volume of patients with unilateral condylar hyperplasia (UCH) with that of patients with a Class III skeletal relation. MATERIALS AND METHODS: Twenty cone-beam computed tomograms of patients were analyzed. Images were divided into 2 groups: 10 from patients with transverse asymmetry of the face and 10 from patients with a Class III facial deformity. Patients' ages ranged from 15 to 30 years. Volumetric data were reconstructed using Dolphin 3D software (Dolphin Imaging & Management Solutions, Chatsworth, CA). This software measured the condylar volume above the deepest point of the sigmoid notch, the lower arch midline deviation, and the overjet. RESULTS: The condyle with hyperplasia exhibited the largest volume (1.97 +/- 0.52 cm3) and a statistically significant difference compared with the contralateral condyle (chi2 = 14.30; P < .01). The Class III condyle exhibited relative symmetry of volume between the left and right sides. These condyles exhibited a larger volume compared with the non-hyperplastic condyles in the UCH group, with a statistically significant difference (chi2 = 6.22; P = .013; chi2 = 5.50; P = .019). CONCLUSIONS: Hyperplastic condyles were similar in volume to the condyles of patients with mandibular prognathism, suggesting that patients with a Class III skeletal relation could exhibit bilateral condylar hyperplasia. PMID- 27720721 TI - What Name Best Represents Our Specialty? Oral and Maxillofacial Surgeon Versus Oral and Facial Surgeon. AB - PURPOSE: To determine whether changing "oral and maxillofacial surgeon" (OMS) to "oral and facial surgeon" improves the perception and awareness of the OMS's role and surgical scope of practice in undergraduate biomedical and dental students. MATERIALS AND METHODS: This cross-sectional study requested undergraduate and dental students to select 1 of 5 specialists to treat 21 conditions. Two different surveys were presented: 1 designating specialists as "oral and maxillofacial surgeons" and 1 designating specialists as "oral and facial surgeons." The independent variable was the specialist "oral and maxillofacial surgeon" or "oral and facial surgeon." The dependent variables included specialists chosen for the procedure (ear, nose, and throat surgeon; OMS vs oral and facial surgeon; plastic surgeon; periodontist; and "other"). The test of proportions (z test) with the Yates correction was performed. RESULTS: The sample was composed of 1,671 undergraduate upper division science students and 568 senior dental students. Results showed that undergraduate students' perception of an OMS's surgical scope increased significantly from 28 to 33% when "oral and facial surgeon" was used instead of "oral and maxillofacial surgeon." Dental students' perception of an OMS's surgical scope remained the same whether "oral and maxillofacial surgeon" or "oral and facial surgeon" was used. CONCLUSION: The results of this study suggest that using "oral and facial surgeon" instead of "oral and maxillofacial surgeon" increases awareness of an OMS's surgical scope of practice in undergraduate upper division science students, which could be an important step toward increasing the recognition of the profession by the general public and other non-dental medical colleagues. PMID- 27720722 TI - Compartmentalization of the Cell Membrane. AB - Many cell-membrane-associated processes require transient spatiotemporal separation of components on scales ranging from a couple of molecules to micrometers in size. Understanding these processes mechanistically involves understanding how lipids and proteins self-organize and interact with the cell cortex. Here, we review recent advances in dissecting the mechanisms of cell membrane compartmentalization. We introduce the challenges in studying cell membrane organization, the current understanding of how complex membranes self organize to form transient domains, and the role of protein scaffolds in membrane organization. We discuss the formation of signaling domains as an important example of transient membrane compartmentalization. We conclude by pointing to the current limitations of measuring membrane organization in living cells and the steps that are required to advance the field. PMID- 27720724 TI - Brain oscillations and connectivity in autism spectrum disorders (ASD): new approaches to methodology, measurement and modelling. AB - Although atypical social behaviour remains a key characterisation of ASD, the presence of sensory and perceptual abnormalities has been given a more central role in recent classification changes. An understanding of the origins of such aberrations could thus prove a fruitful focus for ASD research. Early neurocognitive models of ASD suggested that the study of high frequency activity in the brain as a measure of cortical connectivity might provide the key to understanding the neural correlates of sensory and perceptual deviations in ASD. As our review shows, the findings from subsequent research have been inconsistent, with a lack of agreement about the nature of any high frequency disturbances in ASD brains. Based on the application of new techniques using more sophisticated measures of brain synchronisation, direction of information flow, and invoking the coupling between high and low frequency bands, we propose a framework which could reconcile apparently conflicting findings in this area and would be consistent both with emerging neurocognitive models of autism and with the heterogeneity of the condition. PMID- 27720723 TI - Direct loop mediated isothermal amplification on filters for quantification of Dehalobacter in groundwater. AB - Nucleic acid amplification of biomarkers is increasingly used to monitor microbial activity and assess remedial performance in contaminated aquifers. Previous studies described the use of filtration, elution, and direct isothermal amplification (i.e. no DNA extraction and purification) as a field-able means to quantify Dehalococcoides spp. in groundwater. This study expands previous work with direct loop mediated isothermal amplification (LAMP) for the detection and quantification of Dehalobacter spp. in groundwater. Experiments tested amplification of DNA with and without crude lysis and varying concentrations of humic acid. Three separate field-able methods of biomass concentration with eight aquifer samples were also tested, comparing direct LAMP with traditional DNA extraction and quantitative PCR (qPCR). A new technique was developed where filters were amplified directly within disposable Gene-Z chips. The direct filter amplification (DFA) method eliminated an elution step and provided a detection limit of 102Dehalobacter cells per 100mL. LAMP with crudely lysed Dehalobacter had a negligible effect on threshold time and sensitivity compared to lysed samples. The LAMP assay was more resilient than traditional qPCR to humic acid in sample, amplifying with up to 100mg per L of humic acid per reaction compared to 1mg per L for qPCR. Of the tested field-able concentrations methods, DFA had the lowest coefficient of variation among Dehalobacter spiked groundwater samples and lowest threshold time indicating high capture efficiency and low inhibition. While demonstrated with Dehalobacter, the DFA method can potentially be used for a number of applications requiring field-able, rapid (<60min) and highly sensitive quantification of microorganisms in environmental water samples.

AB - BACKGROUND: The determination of glycated albumin (GA) has been suggested as an additional parameter having an independent added value respect to that of HbA1c. The determination of glycation gap (gg) has also been proposed, but few studies have addressed its potential impact in the routine evaluation of glycometabolic control. METHODS: A total of 157 subjects presenting normal whole blood cell count, no hemoglobin variants, normal creatinine levels and serum protein electrophoresis patterns were studied. In a second phase, a total of 205 subjects with no restrictions as those of the first phase study, were analyzed. HbA1cwas measured by capillary electrophoresis, glycated albumin by an enzymatic method and their gg were then calculated. RESULTS: The correlation between HbA1c and GA for the subjects of phase 1 was strong (r=0.8927) and significant correlation between gg and age was remarked (r=0.4486). We found 17.1% of phase 2 subjects with gg falling outside the 95% prediction intervals. Various clinical conditions seemed to affect these subjects, in our experience mostly often related to impaired renal function. CONCLUSION: The glycation gap may be useful to alert clinicians about patients under unstable glycemic control or when various pre analytical conditions my affect the reliability of the measurement of GA or HbA1c.

PMID- 27720726 TI - Biomarkers of Morbid Obesity and Prediabetes by Metabolomic Profiling of Human Discordant Phenotypes. AB - Metabolomic studies aimed to dissect the connection between the development of type 2 diabetes and obesity are still scarce. In the present study, fasting serum from sixty-four adult individuals classified into four sex-matched groups by their BMI [non-obese versus morbid obese] and the increased risk of developing diabetes [prediabetic insulin resistant state versus non-prediabetic non-insulin resistant] was analyzed by LC- and FIA-ESI-MS/MS-driven metabolomic approaches. Altered levels of [lyso]glycerophospholipids was the most specific metabolic trait associated to morbid obesity, particularly lysophosphatidylcholines acylated with margaric, oleic and linoleic acids [lysoPC C17:0: R=-0.56, p=0.0003; lysoPC C18:1: R=-0.61, p=0.0001; lysoPC C18:2 R=-0.64, p<0.0001]. Several amino acids were biomarkers of risk of diabetes onset associated to obesity. For instance, glutamate significantly associated with fasting insulin [R=0.5, p=0.0019] and HOMA-IR [R=0.46, p=0.0072], while glycine showed negative associations [fasting insulin: R=-0.51, p=0.0017; HOMA-IR: R=-0.49, p=0.0033], and the branched chain amino acid valine associated to prediabetes and insulin resistance in a BMI-independent manner [fasting insulin: R=0.37, p=0.0479; HOMA IR: R=0.37, p=0.0468]. Minority sphingolipids including specific [dihydro]ceramides and sphingomyelins also associated with the prediabetic insulin resistant state, hence deserving attention as potential targets for early diagnosis or therapeutic intervention.

AB - The sesquiterpenoid methyl farnesoate (MF) is the unepoxidized form of insect juvenile hormone (JH) III, and is considered an equivalent of JH in crustaceans. Degradation of MF is similar to that of JH which occurs through ester hydrolysis by specific carboxylesterases (CXEs). In this study, the full-length cDNAs of two JH esterase-like CXEs were cloned from the swimming crab, Portunus trituberculatus. The predicted amino acid sequences of the two PtCXEs contain the conserved motifs including catalytic triad and oxyanion hole, which are the hallmark of the CXE family proteins. The phylogenetic analysis showed that the two PtCXEs may belong to the hormone/semiochemical processing group of CXE family, indicating their possible roles on metabolism of hormones. Transcripts of both PtCXEs were most abundant in hepatopancreas and the PtCXE2 was also highly expressed in ovary. The mRNA levels of two PtCXEs in hepatopancreas were induced by in vivo MF treatment and eyestalk ablation, further indicating their potential in degrading MF. However, during the ovarian maturation, expression of the two PtCXEs increased significantly in the early-vitellogenic stage, prior to the remarkable rise in hemolymph MF titer reported by our previous studies. Taken together, our results suggest that the two PtCXEs can potentially serve as the MF esterases, but their catalytic activity may not be restricted to MF.

PMID- 27720730 TI - No definite clinical features of immunoglobulin G4-related disease in patients with pulmonary nodular lymphoid hyperplasia. AB - Pulmonary nodular lymphoid hyperplasia (PNLH) may show heavy lymphoplasmacytic infiltrates with increased immunoglobulin G4 (IgG4)-positive plasma cells as in IgG4-related disease (IgG4-RD). However, it is unclear whether PNLH could be a manifestation of IgG4-RD. A recent study reported the presence of Epstein-Barr virus (EBV) in IgG4-related lymphadenopathy. We postulated that a subset of PNLH might represent IgG4-related lung disease with EBV-positive lymphocytes as has been reported in IgG4-related lymphadenopathy. IgG and IgG4 immunohistochemistries were performed on 26 PNLH cases in our files (1994-2014) and on 9 controls including diffuse lymphoid hyperplasia of the lung without nodularity (n=2), usual interstitial pneumonia with increased lymphoplasmacytic infiltrates (n=5), and thoracic lymphadenopathy (n=2). EBV in situ hybridization was performed in the cases with the highest IgG4+ count (n=15). Median IgG4+ plasma cell count in PNLH was 36 cells per high-power field (interquartile range, 7-65) with median IgG4+/IgG+ ratio of 0.24 (interquartile range, 0.12-0.37). Three of 26 cases had a markedly increased IgG4+ count (range, 55-139) and IgG4+/IgG+ ratio (>0.4). Serum IgG4 level available in 1 of these cases was not elevated, and all 3 patients had alternate medical diagnoses. Absolute counts of IgG4+ plasma cells in PNLH did not significantly differ from the other control groups. Result of EBV in situ hybridization was negative in all cases tested. In conclusion, most PNLH cases had low IgG4+ cells, and there was no clinical evidence of IgG4-RD or EBV among those with increased IgG4+ cells.

AB - Prostate cancer management changed in recent times given the recommendation against prostate-specific antigen screening, adherence to active surveillance, and "cytoreductive" surgery. We hypothesized that radical prostatectomy (RP) findings changed as well. All consecutive RPs (n=1348) and first time prostate needle biopsies (n=1719) in a period of 9 years were reviewed. The cohort was separated into 3 groups: (1) from May 2006 to April 2009, (2) from May 2009 to April 2012, and (3) from May 2012 to April 2015. The number of RPs decreased 15% from 551 in group 1 to 476 in group 2 and decreased a further 35% to 311 in group 3. Pure Gleason 6 (grade group 1) decreased from 46% in group 1 to 24% in group 2 (P<.001) to 12% in group 3 (P<.001). Gleason score 4+3=7 (grade group 3) increased from 9.8% in group 1 to 13.4% in group 2 (P=.07) to 20.6% in group 3 (P=.01). Gleason score 8, 9, or 10 (grade groups 4 and 5) increased from 0.9% in group 1 to 8.4% in group 2 (P<.001) to 13.2% in group 3 (P=.04). Pathologic stage pT3 or above increased from 15.5% in group 1 to 29.2% in group 2 (P<.01) to 38.3% in group 3 (P=.01). In needle biopsies, there was no difference in number of cancer diagnoses, number of positive cores, or distribution of grades among 3 groups. More patients with low-risk disease are opting for active surveillance, and patients with high-risk disease are offered cytoreductive surgery. Lack of similar changes in needle biopsies suggests that a decrease in screening is not playing a role in the changes seen at RPs.

AB - Mantle cell lymphoma (MCL) usually harbors the t(11;14)(q13;q32) with overexpression of CCND1 mRNA and transcription of the cyclin D1 nuclear protein. Regardless of CCND1 status, most MCLs also express the SOX11 nuclear protein, which is thus helpful in the diagnosis of the rare CCND1-negative MCLs. Recently, SOX11 has been reported to be often negative in MCLs clinically resembling marginal zone lymphoma and recently defined as "leukemic non-nodal" MCL in the incoming revision of the WHO classification of lymphoid tumors, for which the bone marrow biopsy is commonly the first diagnostic approach. Due to the less aggressive clinical behavior of the latter MCLs, the reliable determination of the SOX11 antigen in decalcified tissue is mandatory. To this end, since little data are available in the literature, four commercially available anti-SOX11 antibodies (two polyclonal and two monoclonal) were tested on 21 positive staging bone marrow (BM) biopsies from cyclin D1/SOX11-positive MCL patients (17 fixed in B5, 4 in 10% buffered formalin) and on 9 positive BM biopsies from leukemic non nodal MCL patients. The results were compared for specificity, sensitivity, staining strength and degree of an additional staining on myeloid precursors, also evaluating possible impact of the different fixatives used. Non-mantle cell lymphomas were also tested to address specificity. All reagents showed high sensitivity but the monoclonal code CMC38221001 provided the highest specificity and the lowest degree of non-lymphoid staining on myeloid cells. Formalin fixation generally improved the performance of most antibodies when compared to B5 fixation. PMID- 27720735 TI - Hypothalamic-pituitary-adrenal axis function in Fragile X Syndrome and its relationship to behaviour: A systematic review. AB - Fragile X Syndrome (FXS) is characterised by features including anxiety and autistic-like behaviour, which led to early hypotheses that aberrant physiological arousal may underlie the behavioural phenotype. In line with this, several lines of evidence suggest that the hypothalamic-pituitary-adrenal (HPA) axis may be altered in the syndrome. This review collates evidence to determine the nature of HPA axis baseline activity and reactivity (as measured by glucocorticoid levels) differences in FXS, and its relationship to behaviour. Through a search of electronic databases, 15 papers were identified which provided data on humans with FXS or the FMR1 knockout mouse model. The findings across studies are mixed, though trends in the findings can be seen, including elevations in cortisol levels, particularly in males. Preliminary findings also highlight associations between cortisol levels and key behaviours associated with the syndrome, such as gaze avoidance. Areas for future research are discussed. PMID- 27720736 TI - The effect of a crunchy pseudo-chewing sound on perceived texture of softened foods. AB - Elderly individuals whose ability to chew and swallow has declined are often restricted to unpleasant diets of very soft food, leading to a poor appetite. To address this problem, we aimed to investigate the influence of altered auditory input of chewing sounds on the perception of food texture. The modified chewing sound was reported to influence the perception of food texture in normal foods. We investigated whether the perceived sensations of nursing care foods could be altered by providing altered auditory feedback of chewing sounds, even if the actual food texture is dull. Chewing sounds were generated using electromyogram (EMG) of the masseter. When the frequency properties of the EMG signal are modified and it is heard as a sound, it resembles a "crunchy" sound, much like that emitted by chewing, for example, root vegetables (EMG chewing sound). Thirty healthy adults took part in the experiment. In two conditions (with/without the EMG chewing sound), participants rated the taste, texture and evoked feelings of five kinds of nursing care foods using two questionnaires. When the "crunchy" EMG chewing sound was present, participants were more likely to evaluate food as having the property of stiffness. Moreover, foods were perceived as rougher and to have a greater number of ingredients in the condition with the EMG chewing sound, and satisfaction and pleasantness were also greater. In conclusion, the "crunchy" pseudo-chewing sound could influence the perception of food texture, even if the actual "crunchy" oral sensation is lacking. Considering the effect of altered auditory feedback while chewing, we can suppose that such a tool would be a useful technique to help people on texture-modified diets to enjoy their food. PMID- 27720737 TI - Relational and procedural memory systems in the goldfish brain revealed by trace and delay eyeblink-like conditioning. AB - The presence of multiple memory systems supported by different neural substrata has been demonstrated in animal and human studies. In mammals, two variants of eyeblink classical conditioning, differing only in the temporal relationships between the conditioned stimulus (CS) and the unconditioned stimulus (US), have been widely used to study the neural substrata of these different memory systems. Delay conditioning, in which both stimuli coincide in time, depends on a non relational memory system supported by the cerebellum and associated brainstem circuits. In contrast, trace conditioning, in which a stimulus-free time gap separates the CS and the US, requires a declarative or relational memory system, thus depending on forebrain structures in addition to the cerebellum. The distinction between the explicit or relational and the implicit or procedural memory systems that support trace and delay classical conditioning has been extensively studied in mammals, but studies in other vertebrate groups are relatively scarce. In the present experiment we analyzed the differential involvement of the cerebellum and the telencephalon in delay and trace eyeblink like classical conditioning in goldfish. The results show that whereas the cerebellum lesion prevented the eyeblink-like conditioning in both procedures, the telencephalon ablation impaired exclusively the acquisition of the trace conditioning. These data showing that comparable neural systems support delay and trace eyeblink conditioning in teleost fish and mammals suggest that these separate memory systems and their neural bases could be a shared ancestral brain feature of the vertebrate lineage.

AB - We recorded neuronal activity from the nidopallium caudolaterale, the avian equivalent of mammalian prefrontal cortex, and the entopallium, the avian equivalent of the mammalian visual cortex, in four birds trained on a differential outcomes delayed matching-to-sample procedure in which one sample stimulus was followed by reward and the other was not. Despite similar incidence of reward-specific and reward-unspecific delay cell types across the two areas, overall entopallium delay activity occurred following both rewarded and non rewarded stimuli, whereas nidopallium caudolaterale delay activity tended to occur following the rewarded stimulus but not the non-rewarded stimulus. These findings are consistent with the view that delay activity in entopallium represents a code of the sample stimulus whereas delay activity in nidopallium caudolaterale represents a code of the possibility of an upcoming reward. However, based on the types of delay cells encountered, cells in NCL also code the sample stimulus and cells in ENTO are influenced by reward. We conclude that both areas support the retention of information, but that the activity in each area is differentially modulated by factors such as reward and attentional mechanisms.

PMID- 27720743 TI - Cognitive correlates of spatial navigation: Associations between executive functioning and the virtual Morris Water Task. AB - Although effective spatial navigation requires memory for objects and locations, navigating a novel environment may also require considerable executive resources. The present study investigated associations between performance on the virtual Morris Water Task (vMWT), an analog version of a nonhuman spatial navigation task, and neuropsychological tests of executive functioning and spatial performance in 75 healthy young adults. More effective vMWT performance (e.g., lower latency and distance to reach hidden platform, greater distance in goal quadrant on a probe trial, fewer path intersections) was associated with better verbal fluency, set switching, response inhibition, and ability to mentally rotate objects. Findings also support a male advantage in spatial navigation, with sex moderating several associations between vMWT performance and executive abilities. Overall, we report a robust relationship between executive functioning and navigational skill, with some evidence that men and women may differentially recruit cognitive abilities when navigating a novel environment. PMID- 27720744 TI - The association of serotonin receptor 3A methylation with maternal violence exposure, neural activity, and child aggression. AB - BACKGROUND: Methylation of the serotonin 3A receptor gene (HTR3A) has been linked to child maltreatment and adult psychopathology. The present study examined whether HTR3A methylation might be associated with mothers' lifetime exposure to interpersonal violence (IPV), IPV-related psychopathology, child disturbance of attachment, and maternal neural activity. METHODS: Number of maternal lifetime IPV exposures and measures of maternal psychopathology including posttraumatic stress disorder (PTSD), major depression and aggressive behavior (AgB), and a measure of child attachment disturbance known as "secure base distortion" (SBD) were assessed in a sample of 35 mothers and children aged 12-42 months. Brain fMRI activation was assessed in mothers using 30-s silent film excerpts depicting menacing adult male-female interactions versus prosocial and neutral interactions. Group and continuous analyses were performed to test for associations between clinical and fMRI variables with DNA methylation. RESULTS: Maternal IPV exposure-frequency was associated with maternal PTSD; and maternal IPV-PTSD was in turn associated with child SBD. Methylation status of several CpG sites in the HTR3A gene was associated with maternal IPV and IPV-PTSD severity, AgB and child SBD, in particular, self-endangering behavior. Methylation status at a specific CpG site (CpG2_III) was associated with decreased medial prefrontal cortical (mPFC) activity in response to film-stimuli of adult male-female interactions evocative of violence as compared to prosocial and neutral interactions. CONCLUSIONS: Methylation status of the HTR3A gene in mothers is linked to maternal IPV-related psychopathology, trauma-induced brain activation patterns, and child attachment disturbance in the form of SBD during a sensitive period in the development of self-regulation. PMID- 27720745 TI - SHH ventralizes the otocyst by maintaining basal PKA activity and regulating GLI3 signaling. AB - During development of the inner ear, secreted morphogens act coordinately to establish otocyst dorsoventral polarity. Among these, Sonic hedgehog (SHH) plays a critical role in determining ventral polarity. However, how this extracellular signal is transduced intracellularly to establish ventral polarity is unknown. In this study, we show that cAMP dependent protein kinase A (PKA) is a key intracellular factor mediating SHH signaling through regulation of GLI3 processing. Gain-of-function experiments using targeted gene transfection by sonoporation or electroporation revealed that SHH signaling inactivates PKA, maintaining a basal level of PKA activity in the ventral otocyst. This, in turn, suppresses partial proteolytic processing of GLI3FL, resulting in a low GLI3R/GLI3FL ratio in the ventral otocyst and the expression of ventral-specific genes required for ventral otocyst morphogenesis. Thus, we identify a molecular mechanism that links extracellular and intracellular signaling, determines early ventral polarity of the inner ear, and has implications for understanding the integration of polarity signals in multiple organ rudiments regulated by gradients of signaling molecules. PMID- 27720746 TI - The role of the autonomic nervous system in control of cardiac and air-breathing responses to sustained aerobic exercise in the African sharptooth catfish Clarias gariepinus. AB - Clarias gariepinus is a facultative air-breathing catfish that exhibits changes in heart rate (fH) associated with air-breaths (AB). A transient bradycardia prior to the AB is followed by sustained tachycardia during breath-hold. This study evaluated air-breathing and cardiac responses to sustained aerobic exercise in juveniles (total length~20cm), and how exercise influenced variations in fH associated with AB. In particular, it investigated the role of adrenergic and cholinergic control in cardiac responses, and effects of pharmacological abolition of this control on air-breathing responses. Sustained exercise at 15, 30 and 45cms-1 in a swim tunnel caused significant increases in fAB and fH, from approximately 5breathsh-1 and 60heartbeatsmin-1 at the lowest speed, to over 60breathsh-1 and 100beatsmin-1 at the highest, respectively. There was a progressive decline in the degree of variation in fH, around each AB, as fAB increased with exercise intensity. Total autonomic blockade abolished all variation in fH during exercise, and around each AB, but fAB responses were the same as in untreated animals. Cardiac responses were exclusively due to modulation of inhibitory cholinergic tone, which varied from >100% at the lowest speed to <10% at the highest. Cholinergic blockade had no effect on fAB compared to untreated fish. Excitatory beta-adrenergic tone was approximately 20% and did not vary with swimming speed, but its blockade increased fAB at all speeds, compared to untreated animals. This reveals complex effects of autonomic control on air-breathing during exercise in C. gariepinus, which deserve further investigation.

AB - The contribution of the Big-Five personality dimensions and locus of control to examinees' physiological responses in the Concealed Information polygraph Test (CIT) was examined for the first time. One hundred and twenty undergraduate students who completed Big Five personality and locus of control questionnaires were instructed to commit a mock theft. They were subsequently tested in the Guilty Actions polygraph Test, a modified version of the CIT. Each of the six sets of items (questions) was repeated twice. Results showed that introversion predicted enhanced Skin Conductance Responses (SCRs) to the critical items only for the first repetition of the first 3 questions which was explained by sensitivity to orienting responses. In contrast, extraversion was linked to Finger Pulse Waveform Length (FPWL) responses to the first repetition of the first 3 questions and was explained by extended and more deliberate information processing due to increased interest in the experiment. Participants high in openness to experience, characterized by intellectual curiosity, responded more strongly on FPWL throughout the test. Lower Neuroticism scores predicted enhanced Respiration Line Length (RLL) responses in the first repetition of the first 3 questions. Internal locus of control predicted higher tonic skin conductance level before and throughout the test. Results were explained by different information processing styles associated with these personality dimensions during various stages of the test. PMID- 27720750 TI - Specificity characterization of the alpha-mating factor hormone by Kex2 protease. AB - Kex2 is a Ca2+-dependent serine protease from S. cerevisiae. Characterization of the substrate specificity of Kex2 is of particular interest because this protease serves as the prototype of a large family of eukaryotic subtilisin-related proprotein-processing proteases that cleave sites consisting of pairs or clusters of basic residues. Our goal was to study the prime region subsite S' of Kex2 because previous studies have only taken into account non-prime sites using AMC substrates but not the specificity of prime sites identified through structural modeling or predicted cleavage sites. Therefore, we used peptides derived from Abz-KR?EADQ-EDDnp and Abz-YKR?EADQ-EDDnp based on the pro-alpha-mating factor sequence. The specificity of Kex2 due to basic residues at P1' is affected by the type of residue in the P3 position. Some residues in P1' with large or bulky side chains yielded poor substrate specificity. The kcat/KM values for peptides with P2' substitutions containing Tyr in P3 were higher than those obtained for the peptides without Tyr. In fact, P' and P modifications mainly promoted changes in kcat and KM, respectively. The pH profile of Kex2 was fit to a double-sigmoidal pH-titration curve. The specificity results suggest that Kex2 might be involved in the processing of the putative cleavage sites in a polypeptide involved in cell elongation, hyphal formation and the processing of a toxin, which result in host cell lysis. In summary, the specificity of Kex2 is dependent on the set of interactions with prime and non-prime subsites, resulting in synergism.

AB - Variability in drug responsivity has prompted the development of Personalized Medicine, which has shown great promise in utilizing genotypic information to develop safer and more effective drug regimens for patients. Similarly, individual variability in learning outcomes has puzzled researchers who seek to create optimal learning environments for students. "Personalized Learning" seeks to identify genetic, neural and behavioral predictors of individual differences in learning and aims to use predictors to help create optimal teaching paradigms. Evidence for Personalized Learning can be observed by connecting research in pharmacogenomics, cognitive genetics and behavioral experiments across domains of learning, which provides a framework for conducting empirical studies from the laboratory to the classroom and holds promise for addressing learning effectiveness in the individual learners. Evidence can also be seen in the subdomain of speech learning, thus providing initial support for the applicability of Personalized Learning to language. PMID- 27720751 TI - Effects of interface mutations on the dimerization of alanine glyoxylate aminotransferase and implications in the mistargeting of the pathogenic variants F152I and I244T. AB - In this work the dimerization process of the minor allelic form of human alanine glyoxylate aminotransferase, a pyridoxal 5'-phosphate enzyme, was investigated. Bioinformatic analyses followed by site-directed mutagenesis, size exclusion chromatography and catalytic activity experiments allowed us to identify Arg118, Phe238 and Phe240 as interfacial residues not essential for transaminase activity but important for dimer-monomer dissociation. The apo and the holo forms of the triple mutant R118A-Mi/F238S-Mi/F240S-Mi display a dimer-monomer equilibrium dissociation constant value at least ~260- and 31-fold larger, respectively, than the corresponding ones of AGT-Mi. In the presence of PLP, the apomonomer of the triple mutant undergoes a biphasic process: the fast phase represents the formation of an inactive PLP-bound monomer, while the slow phase depicts the monomer-monomer association that parallels the regain of transaminase activity. The latter events occur with a rate constant of ~0.02 MUM-1min-1. In the absence of PLP, the apomonomer is also able to dimerize but with a rate constant value ~2700-fold lower. Thereafter, the possible interference with the dimerization process of AGT-Mi exerted by the mutated residues in the I244T-Mi and F152I-Mi variants associated with Primary Hyperoxaluria type 1 was investigated by molecular dynamics simulations. On the basis of the present and previous studies, a model for the dimerization process of AGT-Mi, I244T-Mi and F152I-Mi, which outlines the structural defects responsible for the complete or partial mistargeting of the pathogenic variants, was proposed and discussed. PMID- 27720752 TI - In vivo induction of human chorionic gonadotropin by osmotic pump advances sexual maturation during pre-spawning phase in adult catfish. AB - Gonadal maturation is a critical event wherein gonads, under the influence of several hormones and factors, undergo cyclic morphological and physiological changes to produce functional gametes during the spawning phase. However, artificial induction can be effectively used to advance the maturation of gonad vis-a-vis spawning like behavior in seasonal breeders during the off-breeding season. In the present study, osmotic pumps loaded with 5000IU of human chorionic gonadotropin (hCG) or saline as control were implanted intraperitoneally for 21days during the pre-spawning phase (May-June) in catfish Clarias batrachus and C. gariepinus. Significant increase in gonado-somatic index and sperm motility, and in the levels of certain sex steroids were observed in the hCG treated catfish when compared to control while estradiol-17beta (E2) was low. Histological analysis in hCG treated testis revealed densely packed sperm and/or spermatids inside the lumen wherein the control testis displayed normal characteristics of the pre-spawning phase. In females, histological analysis showed a significant increase in post-vitellogenic full-grown immature follicles as seen in the spawning phase. In accordance with this, the steroid hormone profile correlated well with steroidogenic shift from E2 to 17alpha,20beta-DP indicating oocyte maturation. However, in the control ovaries of C. batrachus, perinucleolar and pre-vitellogenic oocytes were seen to be predominant. In addition, when compared with the control, the hCG treated group displayed a significant increase in the transcripts of several genes associated with gonadal growth. Taken together, artificial induction by slow release of hCG is an effective strategy to advance sexual maturation in catfish in a programmed manner. PMID- 27720753 TI - Ovaprim, a commercial spawning inducer, stimulates gonadotropin subunit gene transcriptional activity: A study correlated with plasma steroid profile, ovulation and fertilization in the catfish Heteropneustes fossilis. AB - The commercial fish spawning inducer Ovaprim (OVP) containing a salmon gonadotropin-releasing hormone analogue and domperidone (a dopamine receptor-2 antagonist) has been widely used as an effective spawning inducer in artificial breeding of fishes. It induces a preovulatory LH surge resulting in final oocyte maturation (FOM) and ovulation through a mechanism involving a steroidogenic shift to secrete a maturation-inducing steroid (MIS). In the present study, a 0.5MUL/g body weight dose of OVP each injected at 0h and 24h intraperitoneally into gravid female catfish, Heteropneustes fossilis resulted in periovulatory changes in gonadotropin (GtH) subunit gene expression and steroid hormone levels. The OVP injections induced ovulation time-dependently from 6h onwards with 100% ovulation recorded from 24h to 48h. The fertilization rate was high from 6h to 18h and declined from 24h onwards. The OVP treatment up regulated the expression of GtH subunit genes differentially. The expression of glycoprotein-alpha (GPalpha) and luteinizing hormone (LHbeta) peaked at 6h and 12h, and declined at 18h and 24h after the first injection. The second OVP injection at 24h elicited only a transient increase in the GPalpha expression at 6h and a sustained increase in the LHbeta expression from 6h to 18h after the second injection, but both transcripts decreased subsequently. The follicle-stimulating hormone (FSHbeta) expression responded to the OVP treatment from 12h onwards and maintained a constant level from 18h to 36h after the first injection; the second dose had little effect. Plasma steroids were differentially altered: the levels of estradiol-17beta decreased while that of the MIS 17,20beta-dihydroxy-4-pregnen 3-one; 17,20beta-DP increased, causing the steroidogenic shift preceding FOM and ovulation. The present results indicate that LHbeta expression coincides with the ovulation response and the late induction and maintenance of the FSH expression may be related to post-ovulatory events in the ovary.

Since many subtypes of P2X receptors are distributed in the mouse retina, it is likely that the modulatory effects of P2X receptor mediated signaling can occur at multiple synaptic levels in the retina. In this study, we investigated whether P2X receptors expressed between the photoreceptor layer and the inner nuclear layer in the mouse retina were physiologically functional, by electroretinography (ERG). In the combined rod-cone ERG and the scotopic ERG, intravitreal injection of PPADS, an antagonist of P2X receptors, had no effects on the amplitude of the a-wave, but decreased the amplitude of the b-wave. In the photopic ERG, intravitreal injection of PPADS significantly decreased the amplitude of both the a-wave and the b-wave. In ex vivo recordings, a decrease in the b-wave amplitude was observed at 20MUM PPADS, confirming that the inhibition of the b-wave by intravitreal injection of PPADS is due to the inhibition of P2X receptors. Our findings suggest that P2X receptor-mediated signaling has a physiological effect in both the rod and the cone pathways in postreceptoral processing.

AB - Socially monogamous prairie voles (Microtus ochrogaster) display remarkable individual variation in social behaviors, which has been associated with differences in early life experience and neuropeptide receptor densities. These differences are also seen in the wild, where approximately 70% of young voles remain in their natal group as non-breeding alloparents, while the other 30% disperse. We investigated whether natural variation in early parental care could contribute to offspring's willingness to "disperse" (willingness to explore) in a laboratory context. Behavioral differences between dispersers and residents could also provide a way to interpret individual variation in other behaviors commonly observed under laboratory conditions. Breeder pairs ranked as high, medium or low contact, according to the amount of early parental care they provided to offspring, were used to produce and rear experimental subjects. Effects of early parental care on the offspring's willingness to disperse were seen at post-natal day 21, with high-contact offspring spending more time in the start cage and low contact offspring spending more time exploring. Variations in parental care were also associated with differences in juvenile and adult behaviors that could potentially encourage philopatry or dispersal behavior in the wild. High-contact offspring displayed less anxiety-like behavior compared to low-contact animals. Low-contact offspring displayed the lowest amount of alloparental care. High contact offspring spent more time in side-by-side contact with a potential partner compared to medium and low-contact offspring. These results suggest that variations in early parental care can impact weanlings' exploratory behavior, but that philopatry is not driven by high anxiety. PMID- 27720756 TI - Behavioural responses of Pacific salmon to chemical disturbance cues during the spawning migration. AB - Many fish that are exposed to a threat release disturbance cues, which are chemicals that alert conspecifics to the presence of the threat. The release of disturbance cues has been well demonstrated in various species of laboratory reared fish. Migratory fish species often exhibit increased cortisol levels and are exposed to numerous stressors during their migrations, which could trigger the release of disturbance cues. We tested the responses of wild migrating sockeye salmon (Oncorhynchus nerka) and pink salmon (O. gorbuscha) to the odours of disturbed and undisturbed conspecifics to determine whether these fish release disturbance cues following exposure to a simulated stressor. Furthermore, we tested the responses of sockeye salmon to water-borne cortisol, following evidence from past studies that this chemical is excreted through the gills of stressed fish, and speculation that endogenous correlates of stress might function as disturbance cues. We found that sockeye salmon avoid the odour of disturbed conspecifics, whereas pink salmon do not. Avoidance occurred in both female and male sockeye salmon, and was associated with an increase in plasma cortisol levels in females, but not in males. We also found no behavioural response to water-borne cortisol, which suggests this chemical does not act as an exogenous disturbance cue in sockeye salmon. Avoidance of disturbed conspecifics could limit exposure to risks during the sockeye salmon spawning migration, but could also delay the rate of migration and thereby accrue reproductive costs.

AB - Seeds of Maackia amurensis constitutes two sialic acid specific agglutinins known as leukagglutinin and hemagglutinin. Maackia amurensis leukagglutinin (MAL) recognizes alpha2-3-linked sialic acid present mainly in N-glycans and composed of two disulfide linked monomers. It exhibits potential N-glycosylation sites (four PNGs) which have been assumed to undergo differential occupancy. In this study we have characterized the site specific macro- and microheterogeneity of monomers in detail by analysing N-glycopeptides and peptides through liquid chromatography coupled to ion trap mass spectrometer in MS3 mode (LC-MSn). We observed the presence of mainly paucimannose N-glycans at Asn61, Asn113 and Asn191 whereas a high mannose type with varying Man5-9 occurs at Asn179. Interestingly Asn179 and Asn191 exhibited differential occupancy which was evident by the presence of non-glycosylated peptides. This has contributed to the difference in molecular mass of monomers upon SDS-PAGE. Further the presence of disulfide linked peptides confirmed the covalent linkage of monomers which also undergoes uniform C-terminal processing. PMID- 27720758 TI - Characterization of a novel protease from Aeribacillus pallidus strain VP3 with potential biotechnological interest. AB - The present study investigates the purification and physico-chemical characterization of an extracellular protease from the Aeribacillus pallidus strain VP3 previously isolated from a geothermal oil-field (Sfax, Tunisia). The maximum protease activity recorded after 22h of incubation at 45 degrees C was 3000U/ml. Pure enzyme, designated as SPVP, was obtained after ammonium sulfate fractionation (40-60%)-dialysis followed by heat-treatment (70 degrees C for 30min) and UNO Q-6 FPLC anion-exchange chromatography. The purified enzyme is a monomer of molecular mass about 29kDa. The sequence of the 25 NH2-terminal residues of SPVP showed a high homology with those of Bacillus proteases. The almost complete inhibition by PMSF and DIFP confirmed that SPVP is a member of serine protease family. Its optima of pH and temperature were pH 10 and 60 degrees C, respectively. Its half-life times at 70 and 80 degrees C were 8 and 4h, respectively. Its catalytic efficiency was higher than those of SAPCG, Alcalase Ultra 2.5L, and Thermolysin type X. SPVP exhibited excellent stability to detergents and wash performance analysis revealed that it could remove blood stains effectively and high resistance against organic solvents. These properties make SPVP a potential candidate for applications in detergent formulations and non-aqueous peptide biocatalysis.

PMID- 27720761 TI - The cutaneous secretion of the casque-headed tree frog Corythomantis greeningi: Biochemical characterization and some biological effects. AB - Corythomantis greeningi is a tree-frog endemic of the Brazilian semi-arid (Caatinga), mainly characterized by the flat, mineralized and spiny head, which is associated with phragmotic habits. It is already known that the skin secretion of this amphibian from both head and body is quite toxic and is used as an efficient chemical defence against predators. However, the biochemical characteristics and pharmacological effects of this secretion are still very little studied. We have tested the crude skin secretion, as well as the ten major fractions obtained by RP-HPLC for nociceptive and edema activity and for in vitro cytotoxicity using murine models. SDS-PAGE analyses demonstrated that the majority of proteins ranging through the gel lie between 55 and 30 kDa. LC-MS analysis showed multiple low molecular mass molecules (200-500 Da), which are consistent with masses of alkaloids and steroids. The crude skin secretion was able to induce fast and persistent edema accompanied by intense dose-dependent nociception. From the 10 tested fractions, five induced both edema and nociception, six fractions were able to induce only edema (80-170% control), and seven fractions induced only nociception (15-30 times compared to control). In addition, inhibition of cell growth (IC50) was demonstrated in murine fibroblasts and melanoma cells. From the data obtained, we confirmed that the skin secretion of C. greeningi is very toxic and is rich in compounds able to directly provoke local inflammation and nociception. Such characteristics are important as part of the chemical defensive repertory of this species. PMID- 27720762 TI - Pharmacological analysis of hemodynamic responses to Lachesis muta (South American bushmaster) snake venom in anesthetized rats. AB - In this work, we examined some mechanisms involved in the hypotension caused by Lachesis muta (South American bushmaster) venom in anesthetized rats. Venom (1.5 mg/kg, i.v.) caused immediate hypotension that was maximal after 5 min and gradually returned to baseline over 60 min. Pretreatment of rats with the non selective nitric oxide synthase (NOS) inhibitor Nomega-nitro-L-arginine methyl ester (L-NAME) did not attenuate the early phase of venom-induced hypotension, but abolished the recovery phase and resulted in rapid death; a similar effect was observed with the soluble guanylate cyclase (sGC) inhibitor ODQ. In contrast, the hemodynamic responses to venom were not attenuated by the non-selective NOS inhibitor NG-monomethyl-L-arginine, the inducible NOS inhibitor aminoguanidine, the phosphodiesterase 5 inhibitor sildenafil, the adenylate cyclase (AC) inhibitor SQ-22.536, the non-selective muscarinic receptor antagonist atropine, the bradykinin B2 receptor antagonist HOE-140 and the non-selective cyclooxygenase inhibitor indomethacin. Preincubation of venom with the PLA2 inhibitor pBPB had no effect on the immediate hypotension but tended to improve the recovery phase. Neither AEBSF (a serine proteinase inhibitor) nor EDTA (a metalloproteinase inhibitor) prevented the venom-induced hypotension, but AEBSF and not EDTA protected against the lethality of a high dose (3.0 mg/kg, i.v.). There were no marked changes in the ECG parameters with the various treatments, except with L-NAME and ODQ that increased the RR interval. Pulmonary thrombus formation was markedly enhanced by L-NAME and ODQ, and to a lesser extent by pBPB, especially in small vessels, whereas AEBSF and EDTA inhibited thrombus formation. Venom relaxed phenylephrine-precontracted thoracic aorta and pulmonary artery in vitro, with the latter being more sensitive. The relaxation was endothelium-dependent and was inhibited by ODQ but not by H-89, a protein kinase A (PKA) inhibitor. Together, these findings indicate involvement of the NO/sGC/cGMP, but not the AC/cAMP/PKA signaling pathway, in the hemodynamic responses to L. muta venom in rats. Muscarinic mechanisms, kinins and arachidonic acid metabolites are apparently not involved. PMID- 27720760 TI - Trim32 Deficiency Enhances Th2 Immunity and Predisposes to Features of Atopic Dermatitis. AB - Altered innate immunity is a feature of certain skin inflammatory diseases such as psoriasis and atopic dermatitis (AD). In this study, we provide evidence that deficiency in Trim32 (a tripartite motif [TRIM] protein with innate antiviral activity) contributes to a T helper type 2 biased response and predisposes to features of AD in mice. On treatment with the toll-like receptor 7 agonist imquimod (IMQ), Trim32 knockout mice displayed compromised psoriasiform phenotypes and defective T helper type 17 response. Instead, IMQ treatment of Trim32 knockout mice induced AD-like phenotypes with enhanced skin infiltration of eosinophils and mast cells, elevation of T helper type 2 cytokines/chemokines expression, and reduced expression of filaggrin protein expression. Furthermore, although the induction of phosphorylated Stat3 and RelA was compromised after IMQ treatment in the knockout mice, phosphorylated Stat6 was elevated. CC chemokine ligand 20 induction by tumor necrosis factor-alpha and IL-17A was reduced in Trim32-deficient keratinocytes, whereas CC chemokine ligand 5 induction by tumor necrosis factor-alpha and IL-4 was enhanced. In addition, Trim32 protein levels were elevated in mice treated with IMQ. Unlike Trim32 overexpression in psoriasis, TRIM32 levels were low in patients with AD. Based on Trim32 induction by IMQ, the lower levels of TRIM32 in AD skin compared with healthy control and psoriatic skin suggest a defective TRIM32 pathway in AD pathogenesis. PMID- 27720763 TI - Hemodynamic responses to Lachesis muta (South American bushmaster) snake venom in anesthetized rats. AB - In this work, we examined the hemodynamic responses to Lachesis muta (South American bushmaster) venom in anesthetized male Wistar rats. Venom (1.5 mg/kg, i.v.) caused immediate hypotension that was followed by a gradual return towards baseline over 60 min; there were no significant changes in heart rate, ECG parameters and respiratory rate. A higher dose (3 mg/kg, i.v.) caused sustained hypotension, variable bradycardia, respiratory depression and fluctuations in ECG; death occurred within 10-60 min. Venom injected intramuscularly (15 mg/kg) produced a smaller decrease in blood pressure that was more persistent than with 1.5 mg/kg (i.v.). Pre-treatment with atenolol (selective beta1-adrenergic receptor antagonist) potentiated the response to venom (1.5 mg/kg, i.v.) and resulted in a hemodynamic profile similar to that seen with 3 mg/kg (i.v.). Macroscopically, systemic hemorrhage was seen only in the ileum, whereas histological analysis revealed extensive pulmonary hemorrhage; the heart, liver and kidney were generally unaffected. Intravascular pulmonary thrombosis occurred with venom given i.v. and i.m., but was less marked with the latter route. In rat isolated perfused hearts, venom caused a persistent decrease in left ventricular developed pressure but no change in heart rate, coronary flow or ECG; there was tissue necrosis and release of CK-MB that were abolished by pre-treating venom with the PLA2 inhibitor p-bromophenacyl bromide. These results show that in rats L. muta venom causes hypotension, bradycardia and respiratory depression, depending on the dose and route of administration. The hemodynamic responses apparently do not involve direct cardiotoxicity and are modulated by the adrenergic system. PMID- 27720764 TI - Activity correlations between on-like and off-like cells of the rostral ventromedial medulla and simultaneously recorded wide-dynamic-range neurons of the spinal dorsal horn in rats. AB - Considerable evidence supports the notion that on- and off-cells of the rostral ventromedial medulla (RVM) facilitate and depress, respectively, spinal nociceptive transmission. This notion stems from a covariation of on- or off-cell activities and spinal nocifensive reflexes. Such covariation could theoretically be due to their independently responding to a common source, or to an RVM-derived modulation of ventral horn neurons. Here, we tested whether on- and off-cells indeed modulate spinal nociceptive neurons. In deeply anesthetized rats, unitary recordings were simultaneously made from an RVM on-like or off-like cell and a spinal nociceptive neuron that shared a receptive field (RF) at a hind paw. Action potential firing in RVM/spinal neuron pairs was highly correlated, positively for on-like cells and negatively for off-like cells, both during ongoing activity and during application of calibrated noxious pressure to the RF. Microinjection of morphine into RVM induced a correlated decrease in on-like cell/spinal neuron ongoing activity and response to noxious stimulation. RVM morphine induced changes in off-like cell activity that were not correlated with spinal neuronal activity. These results suggest that on-cells exert a positive modulation upon spinal nociceptive neurons, upstream to ventral horn circuits and plausibly at the origin of nociceptive information that eventually reaches the cerebral cortex. On-cells may in this manner contribute to inflammation- and neuropathy-induced increases in withdrawal reflexes. Most significantly, on-cell modulation of nociceptive neurons may be a key factor in clinical pain conditions such as hyperalgesia and allodynia. PMID- 27720765 TI - Induced Neural Differentiation of MMP-2 Cleaved (RADA)4 Drug Delivery Systems. AB - (RADA)4 self-assembling peptides (SAPs) are promising for neural nanoscaffolds with on-demand drug delivery capabilities due to their automated synthesis, in situ assembly, and potential for interaction with and release of biomolecules. Neuroinflammation cued on-demand drug release, due to up-regulated proteases, may well be vital in the treatment of several neurological diseases. In these conditions, releasing neurotrophic growth factors (NTFs) could potentially lead to neuroprotection and neurogenesis. As such, (RADA)4 was made with the high and low activity matrix metalloproteinase 2 (MMP-2) cleaved sequences, GPQG+IASQ (CP1) and GPQG+PAGQ (CP2), the brain-derived NTF secretion stimulating peptide MVG (DP1) and the ciliary NTF analogue DGGL (DP2). PC-12 cell culture was performed to assess bioactive substrate cell adhesion and NTF specific neuronal differentiation. The laminin-derived IKVAV peptide, known for neural cell attachment and interaction, was tethered to (RADA)4-IKVAV and mixed in increasing increments with (RADA)4 for this purpose. With 1 nanomolar MMP-2 treatment, product formation was observed to increase over a three day period, with (RADA)4/(RADA)4-CP1/CP2 mixture, however there was little difference between groups. Smaller CP1/CP2 concentrations displayed comparable (RADA)4 nanoscale morphology to higher concentrations. Acetylcholine esterase and neural differentiation was observed over 3 days with 1 nM MMP-2 treatment according to the following makeup: 8/1/1 (RADA)4/(RADA)4-IKVAV/(RADA)4-CP1/CP2-DP1/DP2. Signalling gradually increased in all groups, and neurite outgrowth was visible after three days. PMID- 27720766 TI - Metformin: An anti-diabetic drug to fight cancer. AB - Since epidemiologic data have highlighted the positive effects of metformin to reduce cancer incidence and mortality, many in vitro and in vivo studies as well as a large number of clinical trials have been conducted in order to study its potential. The many anticancer actions of metformin lead to a cytostatic effect. Two distinct but not exclusive mechanisms can be implicated in these actions. First, by decreasing insulinemia and glycaemia, metformin can block the PI3K/MAPK signalling pathway implicated in cell growth. Second, metformin can directly act on cancer cells by targeting various pathways including tumour metabolism, inflammation, angiogenesis or cancer stem cells, mainly through the activation of the AMPK pathway. Nonetheless, although metformin alone displays chemopreventive properties, it does not seem to be sufficient to treat cancer, raising the need to be combined with other drugs (e.g. chemotherapy or glycolysis inhibitors) in order to synergistically reveal its cytotoxic action. However, in particular conditions such as specific mutations (e.g. LKB, p53 or OCT1) or low glucose availability, metformin alone does have cytotoxic effects. Thus, it is essential to consider the associated biomarkers in order to determine the potential of metformin in different types of cancers. PMID- 27720767 TI - Eyes on systems pharmacology. PMID- 27720768 TI - Application of immuno-PCR assay for the detection of serum IgE specific to Bermuda allergen. AB - In vivo and in vitro tests are the two major ways of identifying the triggering allergens in sensitized individuals with allergic symptoms. Both methods are equally significant in terms of sensitivity and specificity. However, in certain circumstances, in vitro methods are highly preferred because they circumvent the use of sensitizing drugs in patients. In current study, we described a highly sensitive immuno-PCR (iPCR) assay for serum IgE specific to Bermuda allergens. Using oligonucleotide-labelled antibody, we used iPCR for the sensitive detection of serum IgE. The nucleotide sequence was amplified using conventional PCR and the bands were visualized on 2.5% agarose gel. Results demonstrated a 100-fold enhancement in sensitivity of iPCR over commercially available enzyme-linked immunosorbent assay (ELISA) kit. Our iPCR method was highly sensitive for Bermuda specific serum IgE and could be beneficial in allergy clinics. PMID- 27720770 TI - Transurethral Resection Alone Vs Resection Combined With Therapeutic Hydrodistention as Treatment for Ulcerative Interstitial Cystitis: Initial Experience With Propensity Score Matching Studies. AB - OBJECTIVE: To compare the therapeutic efficacy of transurethral resection (TUR) alone with that of TUR combined with therapeutic hydrodistention in patients with ulcerative interstitial cystitis (IC). METHODS: The study subjects were 44 female patients newly diagnosed with IC who underwent TUR to treat ulcerative IC and who were available for follow-up, without recurrence of disease for 12 months. We retrospectively studied both patients who underwent TUR alone (group I) and those who underwent TUR combined with therapeutic hydrodistention (group II). Improvements in pain and voiding symptoms were retrospectively evaluated using a 10-point visual analog scale for pain and a 3-day micturition chart. RESULTS: Group I included 22 patients and group II included 22 patients of mean ages 58.45 +/- 11.01 and 56.27 +/- 11.86 years, respectively. Use of a 10-point visual analog scale showed that pain decreased after the procedures in both groups, but the improvement did not differ between groups. The maximum functional bladder capacities of patients in group I were 161.36, 192.47, and 204.12 mL, respectively, before, at 6 months, and at 12 months after the operation; the maximum functional bladder capacities of patients in group II were 175.45, 263.14, and 291.17 mL, respectively. The voiding frequencies of group I were 12.59, 10.67, and 9.89 times daily, respectively, before, at 6 months, and at 12 months after the operation; the voiding frequencies of group II were 12.95, 9.5, and 8.29 times daily, respectively. CONCLUSION: TUR combined with therapeutic hydrodistention increased bladder capacity and improved voiding symptoms more so than did TUR alone for ulcerative IC. PMID- 27720771 TI - Giant Pheochromocytoma With Leukemoid Reaction: A Case Report. AB - We present a rare case of silent giant pheochromocytoma with leukemoid reaction that has not been reported before. The patient was a 61-year-old woman who complained of progressive weight loss for 3 months. Preoperatively the urine vanillylmandelic acid was 105.54 mg/24 hours. White blood cell count was 56.9 * 109/L. Abdominal ultrasound and computed tomography revealed a mass measuring 18 * 11 cm in the left adrenal area. The patient underwent adrenal gland neoplasm resection. Postoperative histopathologic evaluation confirmed the diagnosis of pheochromocytoma. The leukocyte dropped to normal gradually in 10 days after the operation. Giant pheochromocytoma with leukemoid reaction was very rare. Resection is the only curative treatment. PMID- 27720769 TI - Fear conditioning selectively disrupts noradrenergic facilitation of GABAergic inhibition in the basolateral amygdala. AB - Inappropriate fear memory formation is symptomatic of many psychopathologies, and delineating the neurobiology of non-pathological fear learning may provide critical insight into treating these disorders. Fear memory formation is associated with decreased inhibitory signaling in the basolateral amygdala (BLA), and disrupted noradrenergic signaling may contribute to this decrease. BLA noradrenergic neurotransmission has been implicated in fear memory formation, and distinct adrenoreceptor (AR) subtypes modulate excitatory and inhibitory neurotransmission in this region. For example, alpha1-ARs promote GABA release from local inhibitory interneurons, while beta3-ARs potentiate neurotransmission at lateral paracapsular (LPC) GABAergic synapses. Conversely, beta1/2-ARs amplify excitatory signaling at glutamatergic synapses in the BLA. As increased BLA excitability promotes fear memory formation, we hypothesized that fear learning shifts the balanced regional effects of noradrenergic signaling toward excitation. To test this hypothesis, we used the fear-potentiated startle paradigm in combination with whole cell patch clamp electrophysiology to examine the effects of AR activation on BLA synaptic transmission following fear conditioning in male Long-Evans rats. We first demonstrated that inhibitory neurotransmission is decreased at both local and LPC synapses following fear conditioning. We next measured noradrenergic facilitation of BLA inhibitory signaling at local and LPC synapses using alpha1-and beta3-AR agonists (1 MUM A61603 and 10 MUM BRL37344), and found that the ability of these agents to facilitate inhibitory neurotransmission is disrupted following fear conditioning. Conversely, we found that fear learning does not disrupt noradrenergic modulation of glutamatergic signaling via a beta1/2-AR agonist (1 MUM isoproterenol). Taken together, these studies suggest that fear learning increases BLA excitability by selectively disrupting the inhibitory effects of noradrenaline. PMID- 27720772 TI - Sustained-release Formulation of Mitomycin C to the Upper Urinary Tract Using a Thermosensitive Polymer: A Preclinical Study. AB - OBJECTIVE: To evaluate the safety and feasibility of single and serial instillations of MitoGel into the upper urinary tract using a preclinical swine animal model. MitoGel is a novel sustained release formulation of mitomycin C (MMC) based on RTGel, a proprietary thermosensitive hydrogel technology. MitoGel is liquid at cold temperatures and solidifies to gel state at body temperature. It is intended as a treatment for upper tract urothelial carcinoma, given its ability to provide sustained release of MMC in the upper urinary tract. MATERIALS AND METHODS: We utilized 23 pigs in a 3-phase design. All animals underwent bilateral nephrostomy tube placement. During phase 1, 3 animals underwent antegrade RTGel instillation, imaging, and euthanasia within 12 hours. In phase 2, 10 pigs underwent single antegrade instillation, unilateral nephrectomy 3 days following instillation, and contralateral nephrectomy and euthanasia 30 days following instillation. During phase 3, 10 animals underwent 6 instillations over 3 weeks, followed by bilateral nephrectomy and necropsy 30 days postinstillation. MitoGel (2 mg/mL and 4 mg/mL), aqueous MMC (2 mg/mL and 4 mg/mL), and RTGel alone were evaluated. RESULTS: MitoGel remained visible within the pelvicalyceal system on fluoroscopic and computed tomography imaging for 4-6 hours. MMC plasma levels were well within acceptable safety thresholds. There was no evidence of urinary obstruction, acute kidney injury, sepsis, or myelosuppression. Histologic changes in the urinary system were mild and transient. CONCLUSION: Antegrade MitoGel delivery to the pelvicalyceal system of Yorkshire swine is feasible and safe. Further evaluation of MitoGel in human clinical trials is warranted. PMID- 27720773 TI - Long-term Impacts of Concurrent Posterior Urethral Valve Ablation and Bladder Neck Incision on Urinary Continence and Ejaculation. AB - OBJECTIVE: To assess the long-term impacts of bladder neck incision (BNI) on continence and ejaculatory function of adults who underwent concurrent posterior urethral valve (PUV) ablation and BNI during childhood. MATERIALS AND METHODS: A retrospective chart review was performed to find all adult patients with relevant history. All patients had undergone BNI at 6 o'clock proximal to the verumontanum with caution to leave the adventitia and verumontanum untouched. Charts were reviewed and attempts were made to contact those >=18 years old for follow-up. Patients were specifically evaluated for lower urinary tract symptoms and ejaculatory condition. RESULTS: Among patients treated for PUV between 1998 and 2015 in our center, 21 were >=18 years old at the time of assessment. Until February 2016, we were able to contact 18 patients, all of whom agreed to participate. Mean age was 21.1 +/- 2.9 years with a mean follow-up of 12.5 +/- 4.8 years. None of those contacted had incontinence or dry ejaculations. All considered their ejaculations normal and only one complained of weak ejaculations. Four of 5 patients who consented to perform a semen analysis had normal tests and 1 had low sperm count with abnormal motility. CONCLUSION: BNI is not associated with additional risk of incontinence and dry ejaculation in early adulthood and preserves antegrade ejaculation. Concomitant valve ablation with BNI may provide additional benefits in care of PUV children, especially those with prominent bladder neck and poor bladder function at presentation. PMID- 27720775 TI - The Effect of Anticoagulation on Bleeding-related Complications Following Ureteroscopy. AB - OBJECTIVE: To analyze bleeding-related complications among patients on long-term anticoagulation (AC) undergoing ureteroscopy (URS). Current American Urological Association/International Consultation on Urological Diseases guidelines state that it is safe to continue AC in routine URS; however, these recommendations are based on small case series. PATIENTS AND METHODS: There were 4799 identified URS procedures performed at our institution between June 2009 and February 2016. Records were then retrospectively reviewed to confirm AC use and identify periprocedural complications. Anticoagulant agents evaluated included warfarin, enoxaparin, and non-vitamin K antagonists (ie, rivaroxaban, dabigatran, apibaxan). Patients were excluded if they were taking a concurrent antiplatelet (AP) agent or if additional non-URS procedures were performed. RESULTS: Of the 4799 URS procedures, 272 (5.6%) were done on patients taking chronic AC. Of these, 193 (71%) held AC, 53 (19%) were bridged with enoxaparin, and 26 (10%) continued AC. The median age was 70.2 years and the majority of patients (64.2%) underwent a stone procedure with a stone-free rate of 73%. The overall bleeding related complication rate was 8.1% whereas the significant bleeding-related event rate was 5.9%. Patients continuing AC had the highest significant bleeding related event rate at 15.4% compared to 9% and 3% for those bridged with enoxaparin and those who held, respectively (P = .01). CONCLUSION: Continuation or bridging of AC may increase the risk of perioperative bleeding. The risks and benefits of proceeding with URS on AC must be weighed carefully. Pending external validation, this information may be used for patient counseling and risk stratification. PMID- 27720774 TI - Outcomes and Prognostic Factors of Primary Urethral Cancer. AB - OBJECTIVE: To identify prognostic and treatment factors for primary urethral cancer using a nationwide database. MATERIALS AND METHODS: The National Cancer Database was queried for all cases of primary urethral cancer from 2004 to 2013. Patients with other cancer diagnoses, metastasis, or diagnosis on autopsy were excluded. Proportional hazards regression was used to identify independent predictors of overall survival in patients with primary urethral cancer. Because we hypothesized that predictors may covary by sex, we also performed regression analysis stratified by sex. RESULTS: We identified 1268 men and 869 women with primary urethral cancer. Women tended to have more advanced tumors and adenocarcinoma histology. Median survival for the entire cohort was 49 months (43 55), with 5- and 10-year survival rates of 46% and 31%, respectively. On multivariate analysis, age, race, stage, grade, and Charlson comorbidity index were independent predictors of overall survival. Histology was not a predictor of overall survival in the combined model; however, adenocarcinoma in women increased hazards of death, whereas it decreased hazards of death in men when compared with squamous cell carcinoma. CONCLUSION: Men and women with primary urethral cancer had significant differences in histology, grade, and nodal status. In addition to several expected disease-related factors, black race was associated with increased mortality for patients with primary urethral cancer. PMID- 27720776 TI - X-ray-free Ultrasound-guided Percutaneous Nephrolithotomy: How to Select the Right Patient? AB - OBJECTIVE: To identify factors associated with successful ultrasound guidance for each surgical step of ultrasound-guided percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: Consecutive patients undergoing PCNL between March 2015 and June 2016 were prospectively enrolled. An attempt was made to use ultrasound guidance in renal access, tract dilation, and nephrostomy tube placement for each patient. For steps during which ultrasound guidance was unsuccessful, fluoroscopic screening was applied. Regression analysis identified patient characteristics associated with successful use of ultrasound guidance. RESULTS: A total of 96 patients composed this cohort, with a mean body mass index of 28.7 kg/m2. Mean stone size was 33.1 +/- 18.9 mm, and no hydronephrosis was found in 63.5% of cases. Fluoroscopic screening was required for renal access in 27 cases (28.1%), tract dilation in 38 (39.6%), and nephrostomy tube placement in 80 (83.3%). Multivariate analysis demonstrated that successful ultrasound guidance was significantly associated with the presence of hydronephrosis for renal access and the absence of staghorn calculi for tract dilation. Ultrasound-guided nephrostomy tube placement appeared linked to surgeon experience. CONCLUSION: To achieve completely x-ray-free ultrasound-guided PCNL, the ideal patient should have a hydronephrotic collecting system with no staghorn stone present. For practitioners looking to adopt ultrasound guidance into their PCNL practice, these represent the most appropriate patients to safely initiate a surgical experience. PMID- 27720777 TI - Complementary and Conventional Health-care Utilization Among Young Australian Women With Urinary Incontinence. AB - OBJECTIVE: To examine the relationship between health status and health service utilization (including conventional and complementary and alternative medicine [CAM]) accessed by women experiencing urinary incontinence (UI). Although a high number of younger women report symptoms of UI, such as leaking urine, only a small proportion seek help for these symptoms. MATERIALS AND METHODS: The Australian Longitudinal Study on Women's Health is a large nationally representative study that investigates the health and well-being of women. The 2 most recent surveys (2006 and 2009) of the young cohort (women aged 28-33 and 31 36 respectively) were analyzed. RESULTS: The presence of UI was 8.5% in 2006 (n = 859) and 23.3% in 2009 (n = 1878), whereas the percentage of women who sought help for their UI was 18.6% (n = 160) and 2.2% (n = 182) respectively. Women with UI had poorer health compared with women without UI (P < .005), and women who sought help for their symptoms had poorer physical functioning than women who did not (P < .005). Women who sought help were greater users of conventional and CAM health services (P < .005), including a general practitioner, specialist, hospital doctor, physiotherapist, and naturopath. CONCLUSION: UI is relatively common in younger women. However, many do not seek help. Of the women who do seek care, a large number visit CAM professionals as well as conventional medical professionals, despite a lack of research evaluating the efficacy of CAM treatment. Research is needed to explore CAM practitioner approaches to the treatment of UI and to evaluate the efficacy of these treatments. PMID- 27720778 TI - PBA2, a novel inhibitor of imatinib-resistant BCR-ABL T315I mutation in chronic myeloid leukemia. AB - Chronic Myeloid Leukemia (CML) is largely caused by the Philadelphia (Ph) chromosome carrying the Break point Cluster Region-Abelson (BCR-ABL) oncogene. Imatinib is a BCR-ABL-targeted therapy and considered the standard of care in CML management. Resistance to imatinib therapy often develops because of mutations in the BCR-ABL kinase domain. In this study, we evaluated PBA2, a novel BCR-ABL inhibitor, for its anti-cancer activity against BCR-ABL expressing BaF3 cells. PBA2 shows potent activity against wild-type and T315I mutated BaF3 cells as compared with imatinib. PBA2 inhibited the phosphorylation of BCR-ABL and its downstream signaling in BaF3/WT and BaF3/T315I cells. PBA2 inhibited the mRNA expression of BCR-ABL in BaF3/WT and BaF3/T315I cells. Mechanistically, PBA2 increased the cell population in sub G1 phase of the cell cycle, induced apoptosis and elevated ROS production in both BaF3/WT and BaF3/T315I cells. Taken together, our results indicate that PBA2 exhibits anti-proliferative effects and inhibits the imatinib-resistant T315I BCR-ABL mutation. PBA2 may be a novel drug candidate for overcoming the resistance to imatinib in CML patients. PMID- 27720779 TI - Riboflavin, MTHFR genotype and blood pressure: A personalized approach to prevention and treatment of hypertension. AB - Hypertension is the leading risk factor contributing to mortality worldwide, primarily from cardiovascular disease (CVD), while effective treatment of hypertension is proven to reduce CVD events. Along with the well recognized nutrition and lifestyle determinants, genetic factors are implicated in the development and progression of hypertension. In recent years genome-wide association studies have identified a region near the gene encoding the folate metabolizing enzyme methylenetetrahydrofolate reductase (MTHFR) among eight loci associated with blood pressure. Epidemiological studies, which provide a separate line of evidence to link this gene with blood pressure, show that the 677C->T polymorphism in MTHFR increases the risk of hypertension by 24-87% and CVD by up to 40%, albeit with a large geographical variation in the extent of excess disease risk suggestive of a gene-environment interaction. Emerging evidence indicates that the relevant environmental factor may be riboflavin, the MTHFR co factor, via a novel and genotype-specific effect on blood pressure. Randomized trials conducted in hypertensive patients (with and without overt CVD) pre screened for this polymorphism show that targeted riboflavin supplementation in homozygous individuals (MTHFR 677TT genotype) lowers systolic blood pressure by 6 to 13 mmHg, independently of the effect of antihypertensive drugs. The latest evidence, that the blood pressure phenotype associated with this polymorphism is modifiable by riboflavin, has important clinical and public health implications. For hypertensive patients, riboflavin supplementation can offer a non-drug treatment to effectively lower blood pressure in those identified with the MTHFR 677TT genotype. For sub-populations worldwide with this genotype, better riboflavin status may prevent or delay the development of high blood pressure. Thus riboflavin, targeted at those homozygous for a common polymorphism in MTHFR, may offer a personalized treatment or preventative strategy for hypertension. Further investigations of this novel gene-nutrient interaction in relation to blood pressure, hypertension and hypertension in pregnancy are required. PMID- 27720780 TI - Epigenetics in fibrosis. AB - Fibrosis is a common and important disease. It is a pathological state due to excessive scar formation mediated by an increase in activated fibroblasts that express alpha smooth muscle actin and copious amounts of extracellular matrix molecules. Epigenetics is an area of research that encompasses three main mechanisms: methylation, histone modifications to the tails of histones and also non-coding RNAs including long and short non-coding RNAs. These three mechanisms all seek to regulate gene expression without a change in the underlying DNA sequence. In recent years an explosion of research, aided by deep sequencing technology becoming available, has demonstrated a role for epigenetics in fibrosis, either organ specific like lung fibrosis or more widespread as in systemic sclerosis. While the great majority of epigenetic work in fibrosis is centered on histone codes, more recently the non-coding RNAs have been examined in greater detail. It is known that one modification can affect the other and cross-talk among all three adds a new layer of complexity. This review aims to examine the role of epigenetics in fibrosis, evaluating all three mechanisms, and to suggest possible areas where epigenetics could be targeted therapeutically. PMID- 27720781 TI - Failed Primary Bladder Exstrophy Closure with Osteotomy: Multivariable Analysis of a 25-Year Experience. AB - PURPOSE: Successful primary bladder exstrophy closure provides the best opportunity for patients to achieve a functional closure and urinary continence regardless of the method of repair. Use of osteotomy during initial closure has significantly improved success rates. However, failures can still occur. We identify factors that contribute to a failed primary exstrophy closure with osteotomy. MATERIALS AND METHODS: We reviewed a prospectively maintained institutional database for classic bladder exstrophy cases primarily closed with osteotomy at our institution or referred after primary closure between 1990 and 2015. Data were collected regarding patient gender, closure, osteotomy, immobilization, orthopedics and perioperative pain control. Univariate and multivariable analyses were performed to determine predictors of failure. RESULTS: A total of 156 patients met inclusion criteria. Overall failure rate was 30% (13% from our institution and 87% from referrals). On multivariable analysis use of Buck traction (OR 0.11, 95% CI 0.02-0.60, p = 0.011) and immobilization time greater than 4 weeks (OR 0.19, 95% CI 0.04-0.86, p = 0.031) had significantly lower odds of failure. Osteotomy performed by general orthopedic surgeons had significantly higher odds of failure (OR 23.47, 95% CI 1.45-379.19, p = 0.027). Type of osteotomy and use of epidural anesthesia did not significantly impact failure rates. CONCLUSIONS: Proper immobilization with modified Buck traction and external fixation, immobilization time greater than 4 weeks and undergoing osteotomy performed by a pediatric orthopedic surgeon are crucial factors for successful primary closure with osteotomy. PMID- 27720783 TI - Clinical Outcome of Patients with Fibrosis/Necrosis at Post-Chemotherapy Retroperitoneal Lymph Node Dissection for Advanced Germ Cell Tumors. AB - PURPOSE: Fibrosis accounts for approximately 50% of histological findings at post chemotherapy retroperitoneal lymph node dissection, and is associated with reported relapse rates of 10% to 15%. We characterized patients with fibrosis at post-chemotherapy retroperitoneal lymph node dissection and identified predictors of adverse outcomes in this group. MATERIALS AND METHODS: We reviewed the medical records of men who underwent post-chemotherapy retroperitoneal lymph node dissection between 1989 and 2013 with histological findings of necrosis/fibrosis. With few exceptions post-chemotherapy retroperitoneal lymph node dissection after 1999 was performed with a bilateral template. Clinical, pathological and treatment related data were reported. Cox regression models were built to identify predictors of disease recurrence. RESULTS: The study cohort included 598 men with a median age of 32 years (IQR 25-38). Most cases (397 of 547, 73%) were classified as IGCCCG good risk, with no significant differences in risk classification before and after 1999 (p=0.55). Median followup was 7.3 years (IQR 3.2-12.3). The 5-year recurrence-free and overall survival rates were 94% and 96%, respectively. Overall 36 patients had disease recurrence, most of which was distant or outside the retroperitoneal lymph node dissection template. Procedures performed after 1999 and the presence of embryonal cell carcinoma on primary histology were associated with improved recurrence-free survival on multivariate analysis (p <0.01). CONCLUSIONS: Disease recurrence in patients with fibrosis at post-chemotherapy retroperitoneal lymph node dissection is an uncommon yet significant event, which is less likely to occur in patients treated after 1999 and in those with embryonal carcinoma on primary histology. PMID- 27720782 TI - Comparative Effectiveness of Cancer Control and Survival after Robot-Assisted versus Open Radical Prostatectomy. AB - PURPOSE: Robot-assisted surgery has been rapidly adopted in the U.S. for prostate cancer. Its adoption has been driven by market forces and patient preference, and debate continues regarding whether it offers improved outcomes to justify the higher cost relative to open surgery. We examined the comparative effectiveness of robot-assisted vs open radical prostatectomy in cancer control and survival in a nationally representative population. MATERIALS AND METHODS: This population based observational cohort study of patients with prostate cancer undergoing robot-assisted radical prostatectomy and open radical prostatectomy during 2003 to 2012 used data captured in the SEER (Surveillance, Epidemiology, and End Results)-Medicare linked database. Propensity score matching and time to event analysis were used to compare all cause mortality, prostate cancer specific mortality and use of additional treatment after surgery. RESULTS: A total of 6,430 robot-assisted radical prostatectomies and 9,161 open radical prostatectomies performed during 2003 to 2012 were identified. The use of robot assisted radical prostatectomy increased from 13.6% in 2003 to 2004 to 72.6% in 2011 to 2012. After a median followup of 6.5 years (IQR 5.2-7.9) robot-assisted radical prostatectomy was associated with an equivalent risk of all cause mortality (HR 0.85, 0.72-1.01) and similar cancer specific mortality (HR 0.85, 0.50-1.43) vs open radical prostatectomy. Robot-assisted radical prostatectomy was also associated with less use of additional treatment (HR 0.78, 0.70-0.86). CONCLUSIONS: Robot-assisted radical prostatectomy has comparable intermediate cancer control as evidenced by less use of additional postoperative cancer therapies and equivalent cancer specific and overall survival. Longer term followup is needed to assess for differences in prostate cancer specific survival, which was similar during intermediate followup. Our findings have significant quality and cost implications, and provide reassurance regarding the adoption of more expensive technology in the absence of randomized controlled trials. PMID- 27720784 TI - Resolving incongruence: Species of hybrid origin in Columnea (Gesneriaceae). AB - Speciation by hybridization has long been recognized among plants and includes both homoploid and allopolyploid speciation. The numbers of presumed hybrid species averages close to 11% and tends to be concentrated in a subset of angiosperm families. Recent advances in molecular methods have verified species of hybrid origin that had been presumed on the basis of morphology and have identified species that were not initially considered hybrids. Identifying species of hybrid origin is often a challenge and typically based on intermediate morphology, or discrepancies between molecular datasets. Discrepancies between data partitions may result from several factors including poor support, incomplete lineage sorting, or hybridization. A phylogenetic analysis of species in Columnea (Gesneriaceae) indicated significant incongruencies between the cpDNA and nrDNA datasets. Tests that examined whether one or both of the datasets had the phylogenetic signal to reject the topology of the alternate dataset (Shimodaira and Hasegawa [SH] and approximately unbiased [AU] tests) indicated significant differences between the topologies. Splitstree analyses also showed that there was support for the placement of the discrepant taxa in both datasets and that the combined data placed the putative hybrid species in an intermediate position between the two datasets. The genealogical sorting index (GSI) implied that coalescence in nrDNA had occurred in all species where more than a single individual had been sampled, but the GSI value was lower for the cpDNA of most of the putative hybrids, implying that these regions have not yet coalesced in these lineages despite being haploid. The JML test that evaluates simulated species pairwise distances against observed distances also implies that observed nrDNA data generate shorter distances than simulated data, implying hybridization. It is most likely that C. gigantifolia, C. rubriacuta, and C. sp. nov. represent a lineage from a hybrid ancestor, but C. moorei may be a more recent hybrid and may still be undergoing hybridization with sympatric species. PMID- 27720785 TI - Phylogenomics and species delimitation in the knob-scaled lizards of the genus Xenosaurus (Squamata: Xenosauridae) using ddRADseq data reveal a substantial underestimation of diversity. AB - Middle American knob-scaled lizards of the genus Xenosaurus are a unique radiation of viviparous species that are generally characterized by a flattened body shape and a crevice-dwelling ecology. Only eight species of Xenosaurus, one of them with five subspecies (X. grandis), have been formally described. However, species limits within Xenosaurus have never been examined using molecular data, and no complete phylogeny of the genus has been published. Here, we used ddRADseq data from all of the described and potentially undescribed taxa of Xenosaurus to investigate species limits, and to obtain a phylogenetic hypothesis for the genus. We analyzed the data using a variety of phylogenetic models, and were able to reconstruct a well-resolved and generally well-supported phylogeny for this group. We found Xenosaurus to be composed of four major, allopatric clades concordant with geography. The first and second clades that branch off the tree are distributed on the Atlantic slopes of the Sierra Madre Oriental and are composed of X. mendozai, X. platyceps, and X. newmanorum, and X. tzacualtipantecus and an undescribed species from Puebla, respectively. The third clade is distributed from the Atlantic slopes of the Mexican Transvolcanic Belt in west-central Veracruz south to the Pacific slopes of the Sierra Madre del Sur in Guerrero and Oaxaca, and is composed of X. g. grandis, X. rectocollaris, X. phalaroanthereon, X. g. agrenon, X. penai, and four undescribed species from Oaxaca. The last clade is composed of the four taxa that are geographically closest to the Isthmus of Tehuantepec (X. g. arboreus, X. g. rackhami, X. g. sanmartinensis, and an undescribed species from Oaxaca). We also utilized a variety of molecular species delimitation approaches, including analyses with GMYC, PTP, BPP, and BFD*, which suggested that species diversity in Xenosaurus is at least 30% higher than currently estimated. PMID- 27720786 TI - Impact of Radiation Therapy on Aggressive Care and Quality of Life Near Death. AB - CONTEXT: Radiation therapy (RT) is used with palliative intent in patients with advanced stage cancer. Prior studies, primarily in patients with poor performance status (PS), suggest that RT is associated with aggressive medical care, which may impact patients' quality of life near death (QoD) adversely. OBJECTIVE: This study examines associations between RT use and patients' receipt of aggressive care and QoD based on patients' PS. METHODS: This is a multi-institutional, prospective cohort study of patients with end-stage cancers (N = 312) who were identified as terminally ill at study enrollment. RT use (n = 24; 7.7%) and Eastern Cooperative Oncology Group (ECOG) PS were assessed at study entry (median = 3.8 months before death). Aggressive care near death was operationalized as use of mechanical ventilation and/or resuscitation in the last week of life. QoD was determined using validated caregiver ratings of patients' physical and mental distress in their final week. RESULTS: RT use was associated with higher QoD (8/8, 100.0%, vs. 58/114, 50.9%; P = 0.006) among patients with good PS (ECOG = 1), more aggressive care near death (3/9, 33.3%, vs. 6/107, 5.6%; P = 0.020) among patients with moderate PS (ECOG = 2), and lower QoD (1/7, 14.3%, vs. 28/51, 54.9%; P = 0.046) among patients with poor PS (ECOG = 3). CONCLUSIONS: Targeted use of RT in end-of-life cancer care may benefit patients with good PS, but its use may adversely affect patients with poorer PS. Decisions about RT use in this setting should consider likely end-of-life outcomes based on patients' current PS. PMID- 27720788 TI - Remaining Lifetime After Recognition of Terminal Illness Depends on Diagnosis: A Nationwide Population-Based Cohort Study. AB - CONTEXT: Timely recognition of the terminal phase of life will benefit patients and caregivers as it may facilitate advance care planning and support. OBJECTIVES: The objective of this study was to investigate the remaining lifetime of patients entering a physician-assessed terminal phase and to analyze variation in remaining lifetime according to diagnosis and sociodemographic factors. METHODS: Danish National Health Registers were used to establish a prospective cohort of adult patients formally registered with drug reimbursement due to terminal illness in 2012 and followed until June 2014. RESULTS: Of the 11,062 included patients, the median remaining lifetime was 55 days and 37% of the patients died within the first month. The majority suffered from cancer (89%). Patients with a noncancer disease had the shortest remaining lifetime (17 days), considerably shorter than patients with cancer (59 days). Patients with prostate cancer had the longest remaining lifetime (76 days), whereas those with hematologic cancer had the shortest among cancer patients (41 days). Compared with lung cancer patients, the probability of death within 30 days were higher for patients with noncancer disease and lower for those with prostate or colorectal cancer. Male gender and high age were associated with higher risk of dying within 30 days. CONCLUSION: This study found a median remaining lifetime of 55 days after recognition of terminal illness. Remaining lifetime differed between cancer and noncancer patients and according to age and gender. Increased attention should be directed toward timely recognition of the transition into the terminal phase, especially for patients with noncancer disease. PMID- 27720787 TI - Associations Between Neurotransmitter Genes and Fatigue and Energy Levels in Women After Breast Cancer Surgery. AB - CONTEXT: Fatigue is a common problem in oncology patients. Less is known about decrements in energy levels and the mechanisms that underlie both fatigue and energy. OBJECTIVES: In patients with breast cancer, variations in neurotransmitter genes between lower and higher fatigue latent classes and between the higher and lower energy latent classes were evaluated. METHODS: Patients completed assessments before and monthly for six months after surgery. Growth mixture modeling was used to identify distinct latent classes for fatigue severity and energy levels. Thirty candidate genes involved in various aspects of neurotransmission were evaluated. RESULTS: Eleven single-nucleotide polymorphisms or haplotypes (i.e., ADRB2 rs1042718, BDNF rs6265, COMT rs9332377, CYP3A4 rs4646437, GALR1 rs949060, GCH1 rs3783642, NOS1 rs9658498, NOS1 rs2293052, NPY1R Haplotype A04, SLC6A2 rs17841327, and 5HTTLPR + rs25531 in SLC6A4) were associated with latent class membership for fatigue. Seven single-nucleotide polymorphisms or haplotypes (i.e., NOS1 rs471871, SLC6A1 rs2675163, SLC6A1 Haplotype D01, SLC6A2 rs36027, SLC6A3 rs37022, SLC6A4 rs2020942, and TAC1 rs2072100) were associated with latent class membership for energy. Three of 13 genes (i.e., NOS1, SLC6A2, and SLC6A4) were associated with latent class membership for both fatigue and energy. CONCLUSIONS: Molecular findings support the hypothesis that fatigue and energy are distinct, yet related symptoms. Results suggest that a large number of neurotransmitters play a role in the development and maintenance of fatigue and energy levels in breast cancer patients. PMID- 27720789 TI - Assessment of Breathlessness in Lung Cancer: Psychometric Properties of the Dyspnea-12 Questionnaire. AB - CONTEXT: The Dyspnea-12 (D-12) Questionnaire is a well-validated instrument in respiratory illnesses for breathlessness assessment, but its psychometric properties have not been tested in lung cancer. OBJECTIVE: To demonstrate the psychometric properties of the D-12 in lung cancer patients. METHODS: Baseline data from a lung cancer feasibility trial were adopted for this analysis. D-12 and a series of patient-reported tools, including five Numeric Rating Scales (NRS), the Hospital Anxiety and Depression Scale (HADS), and the Lung Cancer Symptom Scale (LCSS), were used for the psychometric assessment. Spearman's correlation coefficients (rs) were used to estimate the convergent validity of the D-12 with the NRS, HADS, and LCSS. Exploratory factor analysis was performed to examine construct validity. Reliability was tested by Cronbach's alpha and item-to-total correlations. D-12 score difference between patients with or without anxiety, depression, and chronic obstructive pulmonary disease (COPD) was explored to identify its discriminate performance. RESULTS: One hundred and one lung cancer patients were included. There were significantly positive correlations between the D-12 and the HADS, LCSS, and NRS measuring breathlessness severity and its associated affective distress. Factor analysis clearly identified two components (physical and emotional) of the D-12. Cronbach's alpha for D-12 total, physical, and emotional subscales was 0.95, 0.92, and 0.94, respectively. Patients with anxiety or depression demonstrated significantly higher D-12 scores than those without it, and patients with COPD reported significantly more severe breathlessness than those without COPD. CONCLUSION: The D-12 is a valid and reliable self-reported questionnaire for use in breathlessness assessment in lung cancer patients. PMID- 27720792 TI - Capturing the Palliative Home Care Experience From Bereaved Caregivers Through Qualitative Survey Data: Toward Informing Quality Improvement. AB - CONTEXT: Measuring palliative care experience using patient-reported outcomes is becoming important for assessing and improving quality, although most validated outcome tools solely use scaled questions. OBJECTIVES: We analyzed open-text survey responses from bereaved caregivers to identify strengths and weaknesses in the quality of end-of-life care services and to assess the usefulness of qualitative survey data for quality improvement. METHODS: This was a retrospective observational study involving bereaved caregivers of decedents who had received palliative home care services in one of six health care regions in Ontario, Canada. Using the U.K.'s validated Views of Informal Carers-Evaluation of Services survey, respondents were asked what was good and what was bad about the services provided in the last three months of life as separate open-text questions. A qualitative constant comparison approach was used to derive themes from the responses. RESULTS: Among 330 caregivers who completed the survey, 271 (82%) caregivers responded to the open-text questions: 93% of those commented on something that was good about care and 55% on something that was bad. The care experiences were generally positive, with the exception of specific individuals or settings that were perceived as adverse. The qualitative data were more informative about deficiencies in care compared with the quantitative data. CONCLUSION: The qualitative survey data in this study provided key recommendations toward making care more responsive to the needs of dying patients and their families. Capturing the narrative responses of bereaved caregivers is feasible and informative for palliative care program development. PMID- 27720790 TI - Validation of the Family Inpatient Communication Survey. AB - CONTEXT: Although many family members who make surrogate decisions report problems with communication, there is no validated instrument to accurately measure surrogate/clinician communication for older adults in the acute hospital setting. OBJECTIVES: The objective of this study was to validate a survey of surrogate-rated communication quality in the hospital that would be useful to clinicians, researchers, and health systems. METHODS: After expert review and cognitive interviewing (n = 10 surrogates), we enrolled 350 surrogates (250 development sample and 100 validation sample) of hospitalized adults aged 65 years and older from three hospitals in one metropolitan area. The communication survey and a measure of decision quality were administered within hospital days 3 and 10. Mental health and satisfaction measures were administered six to eight weeks later. RESULTS: Factor analysis showed support for both one-factor (Total Communication) and two-factor models (Information and Emotional Support). Item reduction led to a final 30-item scale. For the validation sample, internal reliability (Cronbach's alpha) was 0.96 (total), 0.94 (Information), and 0.90 (Emotional Support). Confirmatory factor analysis fit statistics were adequate (one-factor model, comparative fit index = 0.981, root mean square error of approximation = 0.62, weighted root mean square residual = 1.011; two-factor model comparative fit index = 0.984, root mean square error of approximation = 0.055, weighted root mean square residual = 0.930). Total score and subscales showed significant associations with the Decision Conflict Scale (Pearson correlation -0.43, P < 0.001 for total score). Emotional Support was associated with improved mental health outcomes at six to eight weeks, such as anxiety ( 0.19 P < 0.001), and Information was associated with satisfaction with the hospital stay (0.49, P < 0.001). CONCLUSION: The survey shows high reliability and validity in measuring communication experiences for hospital surrogates. The scale has promise for measurement of communication quality and is predictive of important outcomes, such as surrogate satisfaction and well-being. PMID- 27720791 TI - Impact of Palliative Care Screening and Consultation in the ICU: A Multihospital Quality Improvement Project. AB - CONTEXT: There are few multicenter studies that examine the impact of systematic screening for palliative care and specialty consultation in the intensive care unit (ICU). OBJECTIVE: To determine the outcomes of receiving palliative care consultation (PCC) for patients who screened positive on palliative care referral criteria. METHODS: In a prospective quality assurance intervention with a retrospective analysis, the covariate balancing propensity score method was used to estimate the conditional probability of receiving a PCC and to balance important covariates. For patients with and without PCCs, outcomes studied were as follows: 1) change to "do not resuscitate" (DNR), 2) discharge to hospice, 3) 30-day readmission, 4) hospital length of stay (LOS), 5) total direct hospital costs. RESULTS: In 405 patients with positive screens, 161 (40%) who received a PCC were compared to 244 who did not. Patients receiving PCCs had higher rates of DNR-adjusted odds ratio (AOR) = 7.5; 95% CI 5.6-9.9) and hospice referrals-(AOR = 7.6; 95% CI 5.0-11.7). They had slightly lower 30-day readmissions-(AOR = 0.7; 95% CI 0.5-1.0); no overall difference in direct costs or LOS was found between the two groups. When patients receiving PCCs were stratified by time to PCC initiation, early consultation-by Day 4 of admission-was associated with reductions in LOS (1.7 days [95% CI -3.1, -1.2]) and average direct variable costs (-$1815 [95% CI -$3322, -$803]) compared to those who received no PCC. CONCLUSION: Receiving a PCC in the ICUs was significantly associated with more frequent DNR code status and hospice referrals, but not 30-day readmissions or hospital utilization. Early PCC was associated with significant LOS and direct cost reductions. Providing PCC early in the ICU should be considered. PMID- 27720793 TI - Timing of Advance Directive Completion and Relationship to Care Preferences. AB - CONTEXT: Given recent Medicare rules reimbursing clinicians for engaging in advance care planning, there is heightened need to understand factors associated with the timing of advance directive (AD) completion before death and how the timing impacts care decisions. OBJECTIVE: The purpose of this study was to investigate patterns in timing of AD completion and the relationship between timing and documented care preferences. We hypothesize that ADs completed late in the course of illness or very early in the disease trajectory will reflect higher preferences for aggressive care. METHODS: We conducted a retrospective study using logistic regressions to analyze data from the Health and Retirement Study, a nationally representative longitudinal survey of older adults. RESULTS: The analytic sample included exit interviews conducted from 2000 to 2012 among 2904 proxy reporters of deceased participants who had an AD. Nearly three-quarters (71%) of ADs were completed a year or more before death. Being younger or a racial/ethnic minority, and having lower education, a diagnosis of cancer or lung disease, and an expected death were associated with completing an AD within the three months before death, while having the lowest quartile of assets and memory problems were inversely associated with AD completion. Minorities, those with lower education, expected death, and timing of AD completion were associated with electing aggressive care. CONCLUSION: Early documentation of care wishes may not be associated with an increased likelihood of electing aggressive care; however, ADs completed in the last months of life have higher rates of election of aggressive care. PMID- 27720794 TI - Mindfulness-Based Stress Reduction in Post-treatment Breast Cancer Patients: Immediate and Sustained Effects Across Multiple Symptom Clusters. AB - CONTEXT: Breast cancer survivors (BCS) face adverse physical and psychological symptoms, often co-occurring. Biologic and psychological factors may link symptoms within clusters, distinguishable by prevalence and/or severity. Few studies have examined the effects of behavioral interventions or treatment of symptom clusters. OBJECTIVES: The aim of this study was to identify symptom clusters among post-treatment BCS and determine symptom cluster improvement following the Mindfulness-Based Stress Reduction for Breast Cancer (MBSR(BC)) program. METHODS: Three hundred twenty-two Stage 0-III post-treatment BCS were randomly assigned to either a six-week MBSR(BC) program or usual care. Psychological (depression, anxiety, stress, and fear of recurrence), physical (fatigue, pain, sleep, and drowsiness), and cognitive symptoms and quality of life were assessed at baseline, six, and 12 weeks, along with demographic and clinical history data at baseline. A three-step analytic process included the error-accounting models of factor analysis and structural equation modeling. RESULTS: Four symptom clusters emerged at baseline: pain, psychological, fatigue, and cognitive. From baseline to six weeks, the model demonstrated evidence of MBSR(BC) effectiveness in both the psychological (anxiety, depression, perceived stress and QOL, emotional well-being) (P = 0.007) and fatigue (fatigue, sleep, and drowsiness) (P < 0.001) clusters. Results between six and 12 weeks showed sustained effects, but further improvement was not observed. CONCLUSION: Our results provide clinical effectiveness evidence that MBSR(BC) works to improve symptom clusters, particularly for psychological and fatigue symptom clusters, with the greatest improvement occurring during the six-week program with sustained effects for several weeks after MBSR(BC) training. TRIAL REGISTRATION: Name and URL of Registry: ClinicalTrials.gov. Registration number: NCT01177124. PMID- 27720795 TI - Chronic 14-day exposure to insecticides or methylmercury modulates neuronal activity in primary rat cortical cultures. AB - There is an increasing demand for in vitro test systems to detect neurotoxicity for use in chemical risk assessment. In this study, we evaluated the applicability of rat primary cortical cultures grown on multi-well micro electrode arrays (mwMEAs) to detect effects of chronic 14-day exposure to structurally different insecticides or methylmercury on neuronal activity (mean spike rate; MSR). Effects of chronic exposure to alpha-cypermethrin, endosulfan, carbaryl, chlorpyrifos(-oxon), methylmercury or solvent control [14days exposure, initiated after baseline recording at day in vitro (DIV)7] were studied in five successive recordings between DIV10 and DIV21. The results were compared to effects of acute exposure to these same compounds (activity recorded immediately after the start of exposure after baseline recording at DIV10-11). Chronic 14-day exposure to methylmercury, chlorpyrifos and alpha-cypermethrin inhibited MSR, all with a lowest-observed effect concentration (LOEC) of 0.1MUM, while exposure to endosulfan increased MSR [LOEC: 1MUM]. No significant effects were observed for chlorpyrifos-oxon and carbaryl. Similar to the observations in the chronic 14-day exposure studies, MSR was inhibited by acute 30-min exposure to methylmercury, chlorpyrifos, and alpha-cypermethrin [LOECs: 1MUM, 10MUM, and 1MUM, respectively], whereas endosulfan increased MSR [LOEC: 0.3MUM]. While not observed in the chronic 14-day exposure study, acute exposure to chlorpyrifos oxon and carbaryl resulted in inhibition of MSR [LOECs: 10MUM, and100 MUM, respectively]. Effects on median interspike intervals (mISI; a measure for neuronal firing pattern) were not detected following chronic 14-day or acute 30 min exposure, except for increased mISI at acute chlorpyrifos and alpha cypermethrin exposures at concentrations that also inhibited MSR. These data indicate that the effects of chronic 14-day exposures to methylmercury and insecticides at low concentrations on spontaneous neuronal activity in vitro can be predicted in rapid acute screening studies using mwMEAs.

AB - INTRODUCTION: Manganese is an essential nutrient which can cause adverse effects if ingested to excess or in insufficient amounts, leading to a U-shaped exposure response relationship. Methods have recently been developed to describe such relationships by simultaneously modeling the exposure-response curves for excess and deficiency. These methods incorporate information from studies with diverse adverse health outcomes within the same analysis by assigning severity scores to achieve a common response metric for exposure-response modeling. OBJECTIVE: We aimed to provide an estimate of the optimal dietary intake of manganese to balance adverse effects from deficient or excess intake. METHODS: We undertook a systematic review of the literature from 1930 to 2013 and extracted information on adverse effects from manganese deficiency and excess to create a database on manganese toxicity following oral exposure. Although data were available for seven different species, only the data from rats was sufficiently comprehensive to support analytical modelling. The toxicological outcomes were standardized on an 18-point severity scale, allowing for a common analysis of all available toxicological data. Logistic regression modelling was used to simultaneously estimate the exposure-response profile for dietary deficiency and excess for manganese and generate a U-shaped exposure-response curve for all outcomes. RESULTS: Data were available on the adverse effects of 6113 rats. The nadir of the U-shaped joint response curve occurred at a manganese intake of 2.70mg/kgbw/day with a 95% confidence interval of 2.51-3.02. The extremes of both deficient and excess intake were associated with a 90% probability of some measurable adverse event. CONCLUSION: The manganese database supports estimation of optimal intake based on combining information on adverse effects from systematic review of published experiments. There is a need for more studies on humans. Translation of our results from rats to humans will require adjustment for interspecies differences in sensitivity to manganese. PMID- 27720797 TI - Neuronal prolyl-4-hydroxylase 2 deficiency improves cognitive abilities in a murine model of cerebral hypoperfusion. AB - Episodes of cerebral hypoxia/ischemia increase the risk of dementia, which is associated with impaired learning and memory. Previous studies in rodent models of dementia indicated a favorable effect of the hypoxia-inducible factor (HIF) targets VEGF (vascular endothelial growth factor) and erythropoietin (Epo). In the present study we thus investigated whether activation of the entire adaptive HIF pathway in neurons by cell-specific deletion of the HIF suppressor prolyl-4 hydroxylase 2 (PHD2) improves cognitive abilities in young (3months) and old (18 28months) mice suffering from chronic brain hypoperfusion. Mice underwent permanent occlusion of the left common carotid artery, and cognitive function was assessed using the Morris water navigation task. Under conditions of both normal and decreased brain perfusion, neuronal PHD2 deficiency resulted in improved and faster spatial learning in young mice, which was preserved to some extent also in old animals. The loss of PHD2 in neurons resulted in enhanced hippocampal mRNA and protein levels of Epo and VEGF, but did not alter local microvascular density, dendritic spine morphology, or expression of synaptic plasticity-related genes in the hippocampus. Instead, better cognitive function in PHD2 deficient animals was accompanied by an increased number of neuronal precursor cells along the subgranular zone of the dentate gyrus. Overall, our current pre-clinical findings indicate an important role for the endogenous oxygen sensing machinery, encompassing PHDs, HIFs and HIF target genes, for proper cognitive function. Thus, pharmacological compounds affecting the PHD-HIF axis might well be suited to treat cognitive dysfunction and neurodegenerative processes. PMID- 27720799 TI - Deletion of exons 3 and 4 in the mouse Nr1d1 gene worsens high-fat diet-induced hepatic steatosis. AB - AIMS: To elucidate the role of nuclear receptor subfamily 1, group D, member 1 (Nr1d1) in hepatic lipid metabolism and pathogenesis of nonalcoholic fatty liver diseases, Nr1d1 gene mutant mice, in which the DNA-binding domain (exons 3 and 4) was deleted (Nr1d1 Deltaex3/4), were challenged with a high-fat diet (HFD), and the gene expression patterns that responded to this alteration were profiled. MAIN METHODS: The Nr1d1 Deltaex3/4 mice were fed an HFD for 12weeks. Liver tissues were examined by histology, and lipid droplets were detected by Oil-Red O staining. Serum biochemical analyses were performed to assess markers of liver injury. Microarray analysis was used to profile hepatic gene expression patterns. Functional annotation, upstream prediction, and gene coexpression prediction analyses were performed. KEY FINDINGS: The Nr1d1 Deltaex3/4 mice showed enhanced hepatic steatosis after being challenged with an HFD, but not with a low-fat diet, indicating an interaction between diet and genotype for this phenotypic change. Gene expression profiling revealed that this interaction might involve neutrophil recruitment and the cyclic adenosine monophosphate metabolic pathway. A study of transcription factor binding site enrichment suggested that CCAAT/enhancer-binding protein alpha and hepatocyte nuclear factor 4 alpha were associated with this phenotypic change. SIGNIFICANCE: Loss of DNA binding of Nr1d1 was associated with a deterioration in hepatic steatosis. The interaction between the Nr1d1 Deltaex3/4 genotype with an HFD might mediate these phenotypic changes, probably through a nonclassical transcriptional function of Nr1d1. PMID- 27720798 TI - Blast waves from detonated military explosive reduce GluR1 and synaptophysin levels in hippocampal slice cultures. AB - Explosives create shockwaves that cause blast-induced neurotrauma, one of the most common types of traumatic brain injury (TBI) linked to military service. Blast-induced TBIs are often associated with reduced cognitive and behavioral functions due to a variety of factors. To study the direct effects of military explosive blasts on brain tissue, we removed systemic factors by utilizing rat hippocampal slice cultures. The long-term slice cultures were briefly sealed air tight in serum-free medium, lowered into a 37 degrees C water-filled tank, and small 1.7-gram assemblies of cyclotrimethylene trinitramine (RDX) were detonated 15cm outside the tank, creating a distinct shockwave recorded at the culture plate position. Compared to control mock-treated groups of slices that received equal submerge time, 1-3 blast impacts caused a dose-dependent reduction in the AMPA receptor subunit GluR1. While only a small reduction was found in hippocampal slices exposed to a single RDX blast and harvested 1-2days later, slices that received two consecutive RDX blasts 4min apart exhibited a 26-40% reduction in GluR1, and the receptor subunit was further reduced by 64-72% after three consecutive blasts. Such loss correlated with increased levels of HDAC2, a histone deacetylase implicated in stress-induced reduction of glutamatergic transmission. No evidence of synaptic marker recovery was found at 72h post blast. The presynaptic marker synaptophysin was found to have similar susceptibility as GluR1 to the multiple explosive detonations. In contrast to the synaptic protein reductions, actin levels were unchanged, spectrin breakdown was not detected, and Fluoro-Jade B staining found no indication of degenerating neurons in slices exposed to three RDX blasts, suggesting that small, sub-lethal explosives are capable of producing selective alterations to synaptic integrity. Together, these results indicate that blast waves from military explosive cause signs of synaptic compromise without producing severe neurodegeneration, perhaps explaining the cognitive and behavioral changes in those blast-induced TBI sufferers that have no detectable neuropathology. PMID- 27720800 TI - Redox signaling in rheumatoid arthritis and the preventive role of polyphenols. AB - Rheumatoid arthritis (RA) is an autoimmune, inflammatory joint disease whose exact cause is still not completely known. Reactive oxygen species (ROS) are believed to be involved in the pathogenesis of RA. ROS are produced mostly by the phagocytic cells during oxidative burst and oxidative phosphorylation. Lipids, proteins and nucleic acids get damaged by the overproduction of ROS. Damaging effects of ROS are taken care by the enzymatic and non-enzymatic defence system of the body. Overproduction or inadequate elimination of reactive species leading to oxidative stress has been positively correlated with the disease severity in RA patients. ROS activates signal transduction pathways involved in the inflammatory response in RA. Understanding the complex interplay between signaling pathways might be useful for the development of new and effective therapeutics for RA. In this review we discuss the involvement of reactive species in the pathogenesis of RA and their elimination by antioxidant defence system. Role of various antioxidants/polyphenols which looks quite promising in the treatment of RA have also been discussed. PMID- 27720801 TI - Acute bouts of wheel running decrease cocaine self-administration: Influence of exercise output. AB - Exercise is associated with lower rates of drug use in human populations and decreases drug self-administration in laboratory animals. Most of the existing literature examining the link between exercise and drug use has focused on chronic, long-term exercise, and very few studies have examined the link between exercise output (i.e., amount of exercise) and drug self-administration. The purpose of this study was to examine the effects of acute bouts of exercise on cocaine self-administration, and to determine whether these effects were dependent on exercise output and the time interval between exercise and drug self administration. Female rats were trained to run in automated running wheels, implanted with intravenous catheters, and allowed to self-administer cocaine on a fixed ratio (FR1) schedule of reinforcement. Immediately prior to each test session, subjects engaged in acute bouts of exercise in which they ran for 0, 30, or 60min at 12m/min. Acute bouts of exercise before test sessions decreased cocaine self-administration in an output-dependent manner, with the greatest reduction in cocaine intake observed in the 60-min exercise condition. Exercise did not reduce cocaine self-administration when wheel running and test sessions were separated by 12h, and exercise did not reduce responding maintained by food or responding during a saline substitution test. These data indicate that acute bouts of exercise decrease cocaine self-administration in a time- and output dependent manner. These results also add to a growing body of literature suggesting that physical activity may be an effective component of drug abuse treatment programs. PMID- 27720802 TI - In silico metabolic engineering of Clostridium ljungdahlii for synthesis gas fermentation. AB - Synthesis gas fermentation is one of the most promising routes to convert synthesis gas (syngas; mainly comprised of H2 and CO) to renewable liquid fuels and chemicals by specialized bacteria. The most commonly studied syngas fermenting bacterium is Clostridium ljungdahlii, which produces acetate and ethanol as its primary metabolic byproducts. Engineering of C. ljungdahlii metabolism to overproduce ethanol, enhance the synthesize of the native byproducts lactate and 2,3-butanediol, and introduce the synthesis of non-native products such as butanol and butyrate has substantial commercial value. We performed in silico metabolic engineering studies using a genome-scale reconstruction of C. ljungdahlii metabolism and the OptKnock computational framework to identify gene knockouts that were predicted to enhance the synthesis of these native products and non-native products, introduced through insertion of the necessary heterologous pathways. The OptKnock derived strategies were often difficult to assess because increase product synthesis was invariably accompanied by decreased growth. Therefore, the OptKnock strategies were further evaluated using a spatiotemporal metabolic model of a syngas bubble column reactor, a popular technology for large-scale gas fermentation. Unlike flux balance analysis, the bubble column model accounted for the complex tradeoffs between increased product synthesis and reduced growth rates of engineered mutants within the spatially varying column environment. The two-stage methodology for deriving and evaluating metabolic engineering strategies was shown to yield new C. ljungdahlii gene targets that offer the potential for increased product synthesis under realistic syngas fermentation conditions.

AB - BACKGROUND & AIMS: A strong association between human inflammatory biliary diseases and gut inflammation has led to the hypothesis that gut microbes and lymphocytes activated in the intestine play a role in biliary inflammation. The NOD.c3c4 mouse model develops spontaneous biliary inflammation in extra- and intrahepatic bile ducts. We aimed to clarify the role of the gut microbiota in the biliary disease of NOD.c3c4 mice. METHODS: We sampled cecal content and mucosa from conventionally raised (CONV-R) NOD.c3c4 and NOD control mice, extracted DNA and performed 16S rRNA sequencing. NOD.c3c4 mice were rederived into a germ free (GF) facility and compared with CONV-R NOD.c3c4 mice. NOD.c3c4 mice were also co-housed with NOD mice and received antibiotics from weaning. RESULTS: The gut microbial profiles of mice with and without biliary disease were different both before and after rederivation (unweighted UniFrac-distance). GF NOD.c3c4 mice had less distended extra-hepatic bile ducts than CONV-R NOD.c3c4 mice, while antibiotic treated mice showed reduction of biliary infarcts. GF animals also showed a reduction in liver weight compared with CONV-R NOD.c3c4 mice, and this was also observed in antibiotic treated NOD.c3c4 mice. Co-housing of NOD and NOD.c3c4 mice indicated that the biliary phenotype was neither transmissible nor treatable by co-housing with healthy mice. CONCLUSIONS: NOD.c3c4 and NOD control mice show marked differences in the gut microbiota. GF NOD.c3c4 mice develop a milder biliary affection compared with conventionally raised NOD.c3c4 mice. Our findings suggest that the intestinal microbiota contributes to disease in this murine model of biliary inflammation. LAY SUMMARY: Mice with liver disease have a gut microflora (microbiota) that differs substantially from normal mice. In a normal environment, these mice spontaneously develop disease in their bile ducts. However, when these mice, are raised in an environment devoid of bacteria, the disease in the bile ducts diminishes. Overall this clearly indicates that the bacteria in the gut (the gut microbiota) influences the liver disease in these mice. PMID- 27720805 TI - Gadolinium tissue deposition in brain and bone. AB - Until recognition of the association of nephrogenic systemic fibrosis (NSF) and gadolinium based contrast agents (GBCA) in 2006, these agents were considered extremely safe and without major adverse effects. Even after the recognition of NSF, most physicians considered all GBCAs to be safe when used in patients with normal renal function. This belief has been called into question with the discovery by Kanda in 2014 that gadolinium (Gd) is deposited in brain tissue in patients with normal kidney function. Since that initial report, there have been a number of important studies analyzing the effects of various GBCAs in brain using MR T1 signal intensity measurements and postmortem tissue analyses with inductively coupled plasma mass spectrometry. From these our knowledge and understanding of some key issues surrounding these observations has rapidly evolved. This report reviews and summarizes many recent human and animal studies in combination with past studies to better understand Gd tissue deposition not only in brain but also in bone and skin. Brain tissue deposition was initially demonstrated to occur with less stable group 1 linear agents but recent postmortem studies now confirm that Gd deposition also occurs with more stable linear agents as well as with macrocyclic agents although at much lower levels. Although no adverse health effects have been documented to date, even for the group 1 agents that deposit Gd in higher amounts, the implications for possible unrecognized toxicity is discussed. Future studies are being pursued that may provide better understanding of the various chemical forms of Gd that are deposited in tissues. This may help elucidate relative risks of different types of agents, mechanisms involved and even recognition of potential downstream toxic effects. PMID- 27720806 TI - Cluster analysis of quantitative MRI T2 and T1rho relaxation times of cartilage identifies differences between healthy and ACL-injured individuals at 3T. AB - PURPOSE: To identify focal lesions of elevated MRI T2 and T1rho relaxation times in articular cartilage of an ACL-injured group using a novel cluster analysis technique. MATERIALS AND METHODS: Eighteen ACL-injured patients underwent 3T MRI T2 and T1rho relaxometry at baseline, 6 months and 1 year and six healthy volunteers at baseline, 1 day and 1 year. Clusters of contiguous pixels above or below T2 and T1rho intensity and area thresholds were identified on a projection map of the 3D femoral cartilage surface. The total area of femoral cartilage plate covered by clusters (%CA) was split into areas above (%CA+) and below (%CA ) the thresholds and the differences in %CA(+ or -) over time in the ACL-injured group were determined using the Wilcoxon signed rank test. RESULTS: %CA+ was greater in the ACL-injured patients than the healthy volunteers at 6 months and 1 year with average %CA+ of 5.2 +/- 4.0% (p = 0.0054) and 6.6 +/- 3.7% (p = 0.0041) for T2 and 6.2 +/- 7.1% (p = 0.063) and 8.2 +/- 6.9% (p = 0.042) for T1rho, respectively. %CA- at 6 months and 1 year was 3.0 +/- 1.8% (p > 0.1) and 5.9 +/- 5.0% (p > 0.1) for T2 and 4.4 +/- 4.9% (p > 0.1) and 4.5 +/- 4.6% (p > 0.1) for T1rho, respectively. CONCLUSION: With the proposed cluster analysis technique, we have quantified cartilage lesion coverage and demonstrated that the ACL-injured group had greater areas of elevated T2 and T1rho relaxation times as compared to healthy volunteers. PMID- 27720808 TI - Immune and inflammatory responses to DNA damage in cancer and aging. AB - Genome instability is a hallmark of both cancer and aging processes. Beyond cell autonomous responses, it is known that DNA damage also elicits systemic mechanisms aimed at favoring survival and damaged cells clearance. Among these mechanisms, immune activation and NF-kappaB-mediated inflammation play central roles in organismal control of DNA damage. We focus herein on the different experimental evidences that have allowed gaining mechanistic insight about this relationship. We also describe the functional consequences of defective immune function in cancer development and age-related alterations. Finally, we discuss different intervention strategies based on enhancing immunity or on the modulation of the inflammatory response to improve organism homeostasis in cancer and aging. PMID- 27720807 TI - Mechanical sensitivity and electrophysiological properties of acutely dissociated dorsal root ganglion neurons of rats. AB - Primary afferent fibers use mechanically activated (MA) currents to transduce innocuous and noxious mechanical stimuli. However, it is largely unknown about the differences in MA currents between the afferents for sensing innocuous and noxious stimuli. In the present study, we used dorsal root ganglion (DRG) neurons acutely dissociated from rats and studied their MA currents and also their intrinsic membrane properties. Recorded from small-sized DRG neurons, we found that most of these neurons were mechanically sensitive (MS) showing MA currents. The MS neurons could be classified into nociceptive-like mechanically sensitive (Noci-MS) and non-nociceptive-like mechanically sensitive (nonNoci-MS) neurons based on their action potential shapes. Noci-MS neurons responded to mechanical stimulation with three types of MA currents, rapidly adapting (RA), intermediately adapting (IA), and slowly adapting (SA) currents. In contrast, almost all nonNoci-MS neurons showed RA current type in response to mechanical stimulation. Mechanical thresholds had a broad range for both nonNoci-MS and Noci MS neurons, and the thresholds were not significantly different between them. However, MA current densities were significantly smaller in Noci-MS than in nonNoci-MS neurons. Noci-MS and nonNoci-MS neurons also showed significant differences in their electrophysiological properties including action potential (AP) thresholds and AP firing patterns. These differences may contribute to the differential sensory encoding for innocuous and noxious mechanical stimuli. PMID- 27720809 TI - Persistent strengthening of the prefrontal cortex - nucleus accumbens pathway during incubation of cocaine-seeking behavior. AB - High rates of relapse after prolonged abstinence are often triggered by exposure to drug-associated cues that induce drug craving. Incubation of drug craving is a phenomenon that consists of time-dependent increases in cue-induced drug craving during withdrawal. Plasticity mechanisms in the nucleus accumbens (NAc) underlie drug-seeking responses and involve changes in excitatory synaptic transmission's efficacy. In particular, the prefrontal cortex (PFC) glutamatergic input to the NAc core has been well characterized regarding cocaine-evoked plasticity following non-contingent versus contingent exposure to cocaine or alternatively after protracted abstinence. Still, the synaptic strength during the course of withdrawal compared to drug-naive condition is unknown, since electrophysiological characterizations are mainly performed in brain slices or focus on distinct time points during cocaine-evoked plasticity in vivo. Here we used an incubation paradigm, in which rats had extended accessed to cocaine self administration, and underwent cue-induced reinstatement at withdrawal day 1 and 30. Longitudinal in vivo field potential recordings in awake rats showed that chronic contingent exposure to cocaine strengthened the prelimbic PFC to NAc core pathway when compared to pre-cocaine condition. This strengthening was associated with decreased paired-pulse ratios (PPR), indicative of presynaptic enhancement of glutamate release, which persisted throughout withdrawal. Moreover, both field potential increase and PPR reduction after chronic cocaine exposure correlated with the number of cocaine infusions received during training. The present results together with previous findings of withdrawal-dependent postsynaptic enhancement of the PFC-NAc core pathway, suggest an additional presynaptic strengthening that is initiated during self-administration and maintained throughout abstinence in drug-seeking rats. These cocaine-driven neuroadaptations may provide a neural substrate for maladaptive processing of cues that can ultimately trigger craving and relapse. PMID- 27720810 TI - Impaired fear extinction retention and increased anxiety-like behaviours induced by limited daily access to a high-fat/high-sugar diet in male rats: Implications for diet-induced prefrontal cortex dysregulation. AB - Anxiety disorders and obesity are both common in youth and young adults. Despite increasing evidence that over-consumption of palatable high-fat/high-sugar "junk" foods leads to adverse neurocognitive outcomes, little is known about the effects of palatable diets on emotional memories and fear regulation. In the present experiments we examined the effects of daily 2h consumption of a high-fat/high sugar (HFHS) food across adolescence on fear inhibition and anxiety-like behaviour in young adult rats. Rats exposed to the HFHS diet exhibited impaired retention of fear extinction and increased anxiety-like behaviour in an emergence test compared to rats fed a standard diet. The HFHS-fed rats displayed diet induced changes in prefrontal cortex (PFC) function which were detected by altered expression of GABAergic parvalbumin-expressing inhibitory interneurons and the stable transcription factor DeltaFosB which accumulates in the PFC in response to chronic stimuli. Immunohistochemical analyses of the medial PFC revealed that animals fed the HFHS diet had fewer parvalbumin-expressing cells and increased levels of FosB/DeltaFosB expression in the infralimbic cortex, a region implicated in the consolidation of fear extinction. There was a trend towards increased IBA-1 immunoreactivity, a marker of microglial activation, in the infralimbic cortex after HFHS diet exposure but expression of the extracellular glycoprotein reelin was unaffected. These findings demonstrate that a HFHS diet during adolescence is associated with reductions of prefrontal parvalbumin neurons and impaired fear inhibition in adulthood. Adverse effects of HFHS diets on the mechanisms of fear regulation may precipitate a vulnerability in obese individuals to the development of anxiety disorders. PMID- 27720811 TI - Differential gene expression underlying ovarian phenotype determination in honey bee, Apis mellifera L., caste development. AB - Adult honey bee queens and workers drastically differ in ovary size. This adult ovary phenotype difference becomes established during the final larval instar, when massive programmed cell death leads to the degeneration of 95-99% of the ovariole anlagen in workers. The higher juvenile hormone (JH) levels in queen larvae protect the ovaries against such degeneration. To gain insights into the molecular architecture underlying this divergence critical for adult caste fate and worker sterility, we performed a microarray analysis on fourth and early fifth instar queen and worker ovaries. For the fourth instar we found nine differentially expressed genes (DEGs) with log2FC > 1.0, but this number increased to 56 in early fifth-instar ovaries. We selected 15 DEGs for quantitative PCR (RT-qPCR) analysis. Nine differed significantly by the variables caste and/or development. Interestingly, genes with enzyme functions were higher expressed in workers, while those related to transcription and signaling had higher transcript levels in queens. For the RT-qPCR confirmed genes we analyzed their response to JH. This revealed a significant up-regulation for two genes, a short chain dehydrogenase reductase (sdr) and a heat shock protein 90 (hsp90). Five other genes, including hsp60 and hexamerin 70b (hex70b), were significantly down-regulated by JH. The sdr gene had previously come up as differentially expressed in other transcriptome analyses on honey bee larvae and heat shock proteins are frequently involved in insect hormone responses, this making them interesting candidates for further functional assays. PMID- 27720812 TI - Exercises and Dry Needling for Subacromial Pain Syndrome: A Randomized Parallel Group Trial. AB - : This randomized clinical trial investigated the effectiveness of exercise versus exercise plus trigger point (TrP) dry needling (TrP-DN) in subacromial pain syndrome. A randomized parallel-group trial, with 1-year follow-up was conducted. Fifty subjects with subacromial pain syndrome were randomly allocated to receive exercise alone or exercise plus TrP-DN. Participants in both groups were asked to perform an exercise program of the rotator cuff muscles twice daily for 5 weeks. Further, patients allocated to the exercise plus TrP-DN group also received dry needling to active TrPs in the muscles reproducing shoulder symptoms during the second and fourth sessions. The primary outcome was pain-related disability assessed using the Disabilities of the Arm, Shoulder, and Hand questionnaire. Secondary outcomes included mean current pain and the worst pain experienced in the shoulder during the previous week. They were assessed at baseline, 1 week, and 3, 6, and 12 months after the end of treatment. Analysis was according to intention to treat with mixed analysis of covariance adjusted for baseline outcomes. At 12 months, 47 patients (94%) completed follow-up. Statistically larger improvements (all, P < .01) in shoulder disability was found for the exercise plus TrP-DN group at all follow-up periods (post: Delta -20.6 [95% confidence interval (CI) -23.8 to -17.4]; 3 months: Delta -23.2 [95% CI 28.3 to -18.1)]; 6 months: Delta -23.6 [95% CI -28.9 to -18.3]; 12 months: Delta 13.9 [95% CI -17.5 to -10.3]). Both groups exhibited similar improvements in shoulder pain outcomes at all follow-up periods. The inclusion of TrP-DN with an exercise program was effective for improving disability in subacromial pain syndrome. No greater improvements in shoulder pain were observed. PERSPECTIVE: This study found that the inclusion of 2 sessions of TrP-DN into an exercise program was effective for improving shoulder pain-related disability at short-, medium-, and long-term; however, no greater improvement in shoulder pain was observed. PMID- 27720813 TI - Contribution of amygdala to the pressor response elicited by microinjection of angiotensin II into the bed nucleus of the stria terminalis. AB - The bed nucleus of the stria terminalis (BST) is part of the limbic system located in the rostral forebrain. BST is involved in behavioral, neuroendocrine and autonomic functions, including cardiovascular regulation. The amygdala, plays an important role in mediating the behavioral and physiological responses associated with fear and anxiety, including cardiovascular responses. In a previous study, we showed that microinjection of AngII into the BST produced a pressor and two types of single-unit responses in the BST, short excitatory and long inhibitory. This study was performed to find possible involvement of amygdala in cardiovascular responses elicited by microinjection of AngII into the BST, using blockade of the central nucleus of amygdala (CeA) and single unit recording from the CeA, while injecting AngII into the BST in anesthetized rat. Blockade of CeA attenuated the pressor response to microinjection of AngII into the BST. Eighty-six AngII microinjections were given into the BST and 198 single unit responses were recorded from CeA simultaneously, from which 89 showed a short duration excitatory response and 109 showed no responses. In conclusion, microinjection of AngII into the BST produces a short excitatory single unit response in the CeA, resulting in contribution of amygdala to the resulted pressor response. Taken together, our study and previous studies suggest a plausible hypothesis that these two nuclei perform their cardiovascular functions in cooperation with each other. PMID- 27720814 TI - Live imaging of inhibitory axons: Synapse formation as a dynamic trial-and-error process. AB - In this review I discuss recent live imaging studies that demonstrate that synapses, and in particular inhibitory synapses, are highly dynamic structures. The ongoing changes of presynaptic boutons within axons emphasize the stochastic aspect of inhibitory synapse formation and paint a picture of a dynamic trial-and error process. Furthermore, I discuss recent and previous insights in the molecular and mechanistic pathways that underlie synapse formation, with a specific focus on the formation of inhibitory presynaptic boutons. PMID- 27720817 TI - Microencapsulation of grape polyphenols using maltodextrin and gum arabic as two alternative coating materials: Development and characterization. AB - Phenolic compounds obtained from fruits have recently gained a great attention due to their bioactive roles. However, they are sensitive and they can be easily affected by physicochemical factors that create a great challenge to incorporate them into the food products. Hence, this work aimed to investigate microencapsulation of these compounds to provide a solution for this problem by improving their stability and protecting them against oxidation, light, moisture and temperature. A lab scale spray-dryer was chosen to produce microcapsules of polyphenols using different dextrose equivalents of maltodextrin and gum arabic as a coating material. Two different core: coating material ratios (1:1 and 1:2), three different maltodextrin: gum arabic ratios (10:0, 8:2 and 6:4), and four different inlet temperatures (120, 140, 160, 180 degrees C) were investigated. When all parameters (yields, hygroscopicity, total and surface phenolic contents, antioxidant activity, individual phenolic compounds and particle morphology) were evaluated; the most efficient microcapsules were obtained with an 8:2 ratio of maltodextrin: gum arabic at 140 degrees C inlet temperature. Microcapsules were also comprehensively studied and characterized using scanning electron microscopy (SEM) and high performance liquid chromatography (HPLC). PMID- 27720816 TI - Cytomegalovirus serostatus, inflammation, and antibody response to influenza vaccination in older adults: The moderating effect of beta blockade. AB - Cytomegalovirus (CMV) has been implicated as a factor in immunosenescence, including poor antibody response to vaccination and higher immune activation and inflammation. Some people may be more or less vulnerable to the negative effects of CMV. The present investigation tested the effects of beta-blocker use and chronological age on the associations between CMV and immunity in adults aged 60 91 (N=98; 69% CMV seropositive) who were administered the trivalent influenza vaccine for up to 5years. Peak antibody response, corrected for baseline, and spring (persistent) antibody response, corrected for peak, were assessed, as well as beta-2 microglobulin (beta2MU) and interleukin-6 (IL-6). In multi-level models with years at Level 1 and people at Level 2, CMV serostatus did not predict peak antibody response, but there was a 3-way interaction between CMV serostatus, age, and beta-blockers. Age was negatively associated with peak antibody, but only among adults who were CMV seropositive and taking beta-blockers. CMV seronegative adults who were not taking beta-blockers had the highest antibody persistence. CMV serostatus was not associated with beta2MU or IL-6. Results suggest that CMV+ serostatus may negatively compromise antibody response to a greater degree than inflammatory markers in older adults. Furthermore, older adults who take beta blockers may be more vulnerable to negative effects of age and CMV on peak antibody response, perhaps by virtue of their underlying health condition. PMID- 27720818 TI - SCT: Spinal Cord Toolbox, an open-source software for processing spinal cord MRI data. AB - For the past 25 years, the field of neuroimaging has witnessed the development of several software packages for processing multi-parametric magnetic resonance imaging (mpMRI) to study the brain. These software packages are now routinely used by researchers and clinicians, and have contributed to important breakthroughs for the understanding of brain anatomy and function. However, no software package exists to process mpMRI data of the spinal cord. Despite the numerous clinical needs for such advanced mpMRI protocols (multiple sclerosis, spinal cord injury, cervical spondylotic myelopathy, etc.), researchers have been developing specific tools that, while necessary, do not provide an integrative framework that is compatible with most usages and that is capable of reaching the community at large. This hinders cross-validation and the possibility to perform multi-center studies. In this study we introduce the Spinal Cord Toolbox (SCT), a comprehensive software dedicated to the processing of spinal cord MRI data. SCT builds on previously-validated methods and includes state-of-the-art MRI templates and atlases of the spinal cord, algorithms to segment and register new data to the templates, and motion correction methods for diffusion and functional time series. SCT is tailored towards standardization and automation of the processing pipeline, versatility, modularity, and it follows guidelines of software development and distribution. Preliminary applications of SCT cover a variety of studies, from cross-sectional area measures in large databases of patients, to the precise quantification of mpMRI metrics in specific spinal pathways. We anticipate that SCT will bring together the spinal cord neuroimaging community by establishing standard templates and analysis procedures.

AB - The excessive accumulation of specific cellular proteins or autophagic vacuoles (AVs) within neurons is a pathologic hallmark of neurodegenerative diseases. Constitutive autophagy in neurons prevents abnormal intracellular protein aggregation and is critical for maintaining cell survival. Since our previous study showed that Toll-interacting protein (Tollip)-deficient macrophages had constitutive disruption of endosome-lysosome fusion, we hypothesize that Tollip deficiency may also promote neuron death via blockage of autophagy completion. Indeed, we observed significantly higher levels of neuron death in the brain regions of cerebral cortex, hippocampus, and cerebellum from ApoE-/-/Tollip-/- mice as compared to ApoE-/- mice fed with high fat diet (HFD). We further documented diminished density of neurons and increased ratios of TUNEL positive cells in the hippocampus of ApoE-/-/Tollip-/- mice. The ultrastructural electron microscopy analyses revealed neuron cell shrinkage as well as loss of intracellular structure in brain tissues from ApoE-/-/Tollip-/- mice. There was dramatic accumulation of autophagosomes in the cytoplasm, elevated accumulation of beta-amyloid and alpha-synuclein, and increased levels of p62 and Parkin in the brain tissues from ApoE-/-/Tollip-/- mice as compared to ApoE-/- mice. Our data suggest that Tollip may play a crucial role in sustaining neuron health by facilitating the completion of autophagy, and that Tollip-deficiency may accelerate neuron death related to neurological disease such as Alzheimer's disease. PMID- 27720820 TI - The norepinephrine system and its relevance for multi-component behavior. AB - The ability to execute several actions in a specific temporal order to achieve an overarching goal, a process often termed action cascading or multi-component behavior, is essential for everyday life requirements. We are only at the beginning to understand the neurobiological mechanisms important for these cognitive processes. However, it is likely that the locus coeruleus norepinephrine (LC-NE) system may be of importance. In the current study we examine the relevance of the LC-NE system for action cascading processes using a system neurophysiological approach combining high-density EEG recordings and source localization to analyze event-related potentials (ERPs) with recordings of pupil diameter as a proximate of LC-NE system activity. N=25 healthy participants performed an action cascading stop-change paradigm. Integrating ERPs and pupil diameter using Pearson correlations, the results show that the LC-NE system is important for processes related to multi-component behavior. However, the LC-NE system does not seem to be important during the time period of response selection processes during multi-component behavior (reflected in the P3) as well as during perceptual and attentional selection (P1 and N1 ERPs). Rather, it seems that the neurophysiological processes in the fore period of a possibly upcoming imperative stimulus to initiate multi-component behavior are correlated with the LC-NE system. It seems that the LC-NE system facilitates responses to task-relevant processes and supports task-related decision and response selection processes by preparing cognitive control processes in case these are required during multi component behavior rather than modulating these processes once they are operating.

AB - Despite the wide applications of functional magnetic resonance imaging (fMRI) to mapping brain activation and connectivity in cortical gray matter, it has rarely been utilized to study white-matter functions. In this study, we investigated the spatiotemporal characteristics of fMRI data within the white matter acquired from humans both in the resting state and while watching a naturalistic movie. By using independent component analysis and hierarchical clustering, resting-state fMRI data in the white matter were de-noised and decomposed into spatially independent components, which were further assembled into hierarchically organized axonal fiber bundles. Interestingly, such components were partly reorganized during natural vision. Relative to resting state, the visual task specifically induced a stronger degree of temporal coherence within the optic radiations, as well as significant correlations between the optic radiations and multiple cortical visual networks. Therefore, fMRI contains rich functional information about the activity and connectivity within white matter at rest and during tasks, challenging the conventional practice of taking white-matter signals as noise or artifacts. PMID- 27720822 TI - Genetic basis for high population diversity in Protea-associated Knoxdaviesia. AB - Sexual reproduction is necessary to generate genetic diversity and, in ascomycete fungi, this process is controlled by a mating type (MAT) locus with two complementary idiomorphs. Knoxdaviesia capensis and K. proteae (Sordariomycetes; Microascales; Gondwanamycetaceae) are host-specific saprophytic fungi that show high population diversity within their Protea plant hosts in the Cape Floristic Region of South Africa. We hypothesise that this diversity is the result of outcrossing driven by a heterothallic mating system and sought to describe the MAT1 loci of both species. The available genome assembly of each isolate contained only one of the MAT1 idiomorphs necessary for sexual reproduction, implying that both species are heterothallic. Idiomorph segregation during meiosis, a 1:1 ratio of idiomorphs in natural populations and mating experiments also supported heterothallism as a sexual strategy. Long-range PCR and shot-gun sequencing to identify the opposite idiomorph in each species revealed no sequence similarity between MAT1-1 and MAT1-2 idiomorphs, but the homologous idiomorphs between the species were almost identical. The MAT1-1 idiomorph contained the characteristic MAT1-1-1 and MAT1-1-2 genes, whereas the MAT1-2 idiomorph consisted of the genes MAT1-2-7 and MAT1-2-1. This gene content was similar to that of the three species in the Ceratocystidaceae (Microascales) with characterized MAT loci. The Knoxdaviesia MAT1-2-7 protein contained and alpha domain and predicted intron, which suggests that this gene arose from MAT1-1-1 during a recombination event. In contrast to the Ceratocystidaceae species, Knoxdaviesia conformed to the ancestral Sordariomycete arrangement of flanking genes and is, therefore, a closer reflection of the structure of this locus in the Microascalean ancestor. PMID- 27720821 TI - Field strength dependence of grey matter R2* on venous oxygenation. AB - The relationship between venous blood oxygenation and change in transverse relaxation rate (DeltaR2*) plays a key role in calibrated BOLD fMRI. This relationship, defined by the parameter beta, has previously been determined using theoretical simulations and experimental measures. However, these earlier studies have been confounded by the change in venous cerebral blood volume (CBV) in response to functional tasks. This study used a double-echo gradient echo EPI scheme in conjunction with a graded isocapnic hyperoxic sequence to assess quantitatively the relationship between the fractional venous blood oxygenation (1-Yv) and transverse relaxation rate of grey matter (DeltaR2?GM*), without inducing a change in vCBV. The results demonstrate that the relationship between DeltaR2* and fractional venous oxygenation at all magnet field strengths studied was adequately described by a linear relationship. The gradient of this relationship did not increase monotonically with field strength, which may be attributed to the relative contributions of intravascular and extravascular signals which will vary with both field strength and blood oxygenation. PMID- 27720824 TI - Mechanisms of temperature sensitivity of attenuated Urabe mumps virus. AB - Temperature sensitivity is a phenotype often associated with attenuation of viruses. Previously, we purified several mumps variants from an incompletely attenuated Urabe strain live attenuated vaccine. Here we characterize one isolate that is sensitive to growth at high temperature. This virus was attenuated in a small animal model of mumps virulence, and we identified unique coding substitutions in the hemagglutinin-neuraminidase (HN), the viral polymerase (L) gene, and a non-coding substitution close to the anti-genome promoter sequences. At the non-permissive temperature, transcription of viral mRNAs and production of the replication intermediate were reduced compared to events at the permissive temperature and to a non-ts virulent Urabe virus. As well, synthesis of viral proteins was also reduced at the higher temperature. While the actual sequence substitutions in the ts virus were unique, the pattern of substitutions in HN, L and genome end sequences is similar to another attenuated Urabe virus previously described by us. PMID- 27720823 TI - Higher prevalence of cancer related mutations 1762T/1764A and PreS deletions in hepatitis B virus (HBV) isolated from HBV/HIV co-infected compared to HBV-mono infected Chinese adults. AB - In the era of combination therapy for human immunodeficiency virus (HIV), liver disease including hepatocellular carcinoma (HCC), are the major causes of death for patients co-infected with hepatitis B virus (HBV) and HIV. However, the mechanisms remain obscure. We aimed to determine whether HCC-related HBV mutations including 1762T/1764A double mutation and pre-S deletions occur more frequently in HBV/HIV co-infected individuals compared to HBV mono-infected individuals. In this study, the basic core promoter (BCP) and the preS/S regions of HBV isolated from 61 pairs of HBV/HIV co-infected and HBV mono-infected participants were analyzed. We found that the prevalence of HBV isolates with 1762T/1764A and/or preS deletion mutations was 37.7% (95% CI: 29.1-46.3). The prevalence of these mutations in HBV/HIV co-infected group (52.5%, 95% CI: 40.0 65.0) was significantly higher than in the HBV mono-infected group (23.0%, 95% CI: 12.4-33.6) (X2=11.307, P<0.05). HBV/HIV co-infection was associated with higher viral loads but these higher viral loads were not associated with the higher prevalence of HCC-related HBV mutations. Individually 1762T1764A (44.3%) or preS deletions (23%) occurred more frequently in isolates from co-infected compared to mono-infected individuals (21.3%, 4.9%, respectively) (X2=7.290, P<0.05; X2=8.270, P<0.05). Moreover, 1762T/1764A and preS deletions occurred more frequently in genotypes C and I compared to genotype B (p<0.05). Multivariate analysis revealed that co-infection with HIV was associated with the development of both 1762T/1764A ((RR: 2.932(1.325-6.488)) and preS deletions ((RR: 5.759(1.562-21.235)). These results demonstrate that co-infection with HIV was associated with increased prevalence of HCC-related mutations in HBV isolates from Chinese patients. PMID- 27720825 TI - Importance of latency and amplitude values of recurrent laryngeal nerve during thyroidectomy in diabetic patients. AB - BACKGROUND: Diabetes mellitus may cause degeneration in the myelin and/or axonal structures of peripheral nerves. The aim of this study was to investigate the effects of diabetic neuropathy on intraoperative neuromonitoring findings such as latency and amplitude values of the recurrent laryngeal nerves during thyroidectomy. To our knowledge this is the first study to report comparison of the electrophysiologic features of diabetic and non-diabetic patients. MATERIALS AND METHODS: One-hundred-and-eleven consecutive patients who received neuromonitoring during thyroidectomy between 2013 and 2015 were included to study. The patients were divided into two groups according to the presence of diabetes mellitus. Pre-thyroidectomy and post thyroidectomy motor response latency and amplitude values of recurrent laryngeal nerves were compared between groups. Neuromonitoring findings, demographic data and postoperative complications were evaluated. RESULTS: The diabetic group consisted of 29 (26.1%) patients while 82 (73.9%) patients were in non-diabetic group. The mean post thyroidectomy amplitude values (millivolts-mV) of the recurrent laryngeal nerve were significantly lower in diabetic group (0.51 +/- 0.26 mV vs. 0,70 +/- 0,46 mV, p < 0.05), whereas the latency values were significantly higher (2.50 +/- 0.86 ms vs. 1.85 +/- 0.59 ms, p < 0.01) compared to non-diabetic group. Additionally, post-thyroidectomy latency values were significantly increased compared to the pre-thyroidectomy latency values (2.50 +/- 0.86 ms vs. 2.02 +/- 0.43 ms) in diabetic group patients (p < 0.05). Although postoperative complication rates were higher in diabetic group (10.3% vs. 5.9%), there were no statistical significance differences. CONCLUSIONS: Prolonged latency and decreased amplitude values in recurrent laryngeal nerves of diabetic patients show that diabetic neuropathy of the recurrent laryngeal nerves develop similarly to the peripheral nerves. Increased post-thyroidectomy latency values reveal that the recurrent laryngeal nerve is more susceptible to surgical trauma in diabetic patients. PMID- 27720826 TI - The Ciona intestinalis cleavage clock is independent of DNA methylation. AB - The initiation of embryonic gene expression in ascidian embryos appears to be tightly regulated by the number of DNA replication cycles. DNA methylation is thought to contribute to the clock mechanism that counts the rounds of DNA replication. We used mass spectrometry and whole genome bisulfite sequencing to characterize DNA methylation changes that occur in early developmental stages of the ascidian, Ciona intestinalis. We found that global DNA methylation in early Ciona development was static, and a base-wise comparison between the genomes of consecutive developmental stages found no DNA demethylation that was related to zygotic gene activation. Additionally, 5hmC was hardly detected by mass spectrometry in the developmental samples, suggesting a lack of demethylation mediated by ten eleven translocation (TET) methylcytosine dioxygenase in C. intestinalis. We conclude that DNA methylation is not involved in regulating DNA replication-dependent transcriptional activation. PMID- 27720827 TI - Timing of Surgery after Neoadjuvant Chemoradiation in Locally Advanced Non-Small Cell Lung Cancer. AB - INTRODUCTION: A subset of patients with potentially resectable clinical stage IIIA NSCLC are managed with trimodality therapy. However, little data exist to guide the timing of surgery after neoadjuvant therapy. This study examined whether the time interval between neoadjuvant chemoradiation (NCRT) and surgical resection affects overall survival. METHODS: Patients with clinical stage IIIA disease (T1-3 N2) NSCLC who underwent NCRT were identified in the National Cancer Data Base (NCDB) between 2004 and 2012 and categorized on the basis of the interval between chemoradiation and surgery (0 to <=3, >3 to <=6, >6 to <=9, and >9 to <=12 weeks). Other clinical stages were excluded. The Kaplan-Meier method and log-rank tests were used to compare overall survival rates, and a bootstrapped Cox proportional hazards model was used to determine significant contributors to overall survival. RESULTS: Of the 1623 patients identified, 7.9% underwent an operation 0 to 3 weeks or less after NCRT, 50.5% underwent an operation greater than 3 and less than or equal to 6 weeks after NCRT, 31.9% underwent an operation greater than 6 and less than or equal to 9 weeks after NCRT, and 9.6% underwent an operation greater than 9 and less than or equal to 12 weeks after NCRT. Multivariate survival analysis demonstrated no significant difference in survival in those who underwent an operation within 6 weeks of NCRT. However, significant drops in overall survival were observed in those who had an operation greater than 6 and less than or equal to 9 weeks after NCRT (hazard ratio = 1.33, 95% confidence interval: 1.01-1.76, p = 0.043) and greater than 9 and less than or equal to 12 weeks after NCRT (hazard ratio = 1.44, 95% confidence interval: 1.04-2.01, p = 0.030). CONCLUSIONS: The findings from this retrospective study suggest that overall survival may be significantly lower in patients with clinical stage IIIA N2 NSCLC who undergo an operation later than 6 weeks after NCRT. These results discourage unnecessary delays in surgery. PMID- 27720828 TI - Wild type agr-negative livestock-associated MRSA exhibits high adhesive capacity to human and porcine cells. AB - Methicillin-resistant Staphylococcus aureus (MRSA) is one of the leading causes of nosocomial infections and a major public health concern worldwide. During the last decade, MRSA of CC398 have emerged as important colonizers of livestock. These strains also represent an increasing cause of human infections. A recent study reporting a new dominant spa type among MRSA from Finish fattening pigs (CC398/t2741) identified a strain lacking both the global virulence regulator gene locus agr and the adhesion gene fnbB. The aim of this study was to characterize this agr/fnbB-negative livestock-associated MRSA strain in terms of growth, hemolysis and adhesive capacity, and to provide data on its genomic background. To this end, growth curves and hemolysis patterns were generated and adhesion assays on human keratinocyte and porcine nasal mucosa cell lines were performed. Whole genome sequencing was used to determine the nature and extent of the relevant deletions in the livestock strains. For comparison, an agr-positive, fnbB-negative CC398/t2741 strain from the same pig herd, an agr/fnbB- positive CC398/t034 strain from another pig herd and one human MRSA strain and its isogenic Deltaagr knockout mutant were used. The agr-negative strains adhered significantly better to human and porcine host cells than the agr-positive control strains. For the agr-positive porcine MRSA strains, cytotoxic effects on porcine mucosal cells were observed. The strong adhesive capacity of the naturally agr-negative livestock-associated MRSA, in combination with diminished cytotoxic effects, is likely favorable for inducing persistent colonization in pigs. Independently of the host cell type, similar adhesive capacities of the naturally agr-negative livestock-associated MRSA and the human MRSA strain were shown. Our results indicate that loss of agr in the livestock-associated MRSA strain investigated in this study may have increased its potential to be transmitted to and amongst humans. PMID- 27720829 TI - The SULSA Assay Development Fund: accelerating translation of new biology from academia to pharma. AB - With industry increasingly sourcing preclinical drug discovery projects from academia it is important that new academic discoveries are enabled through translation with HTS-ready assays. However, many scientifically interesting, novel molecular targets lack associated high-quality, robust assays suitable for hit finding and development. To bridge this gap, the Scottish Universities Life Sciences Alliance (SULSA) established a fund to develop assays to meet quality criteria such as those of the European Lead Factory. A diverse project portfolio was quickly assembled, and a review of the learnings and successful outcomes showed this fund as a new highly cost-effective model for leveraging significant follow-on resources, training early-career scientists and establishing a culture of translational drug discovery in the academic community. PMID- 27720830 TI - Transcriptome analysis of the responses to methyl methanesulfonate treatment in mouse pachytene spermatocytes and round spermatids. AB - Spermatogenesis is threatened by DNA alkylating agents, one major category of DNA damaging agents. Currently, little is known about the alterations in transcriptome profiling of the mouse spermatogenic cells in response to DNA alkylation at distinct stages of spermatogenesis. In this study, RNA sequencing (RNA-seq) was performed in pachytene spermatocytes (PS) and round spermatids (RS) at 0 or 30min following Methyl Methanesulfonate (MMS) treatment and with untreated controls. A large number of differentially expressed genes (DEGs) were identified by comparison of the three groups in PS and RS, respectively. Functional analyses of all DEGs highlighted the protein ubiquitination pathway and DNA damage response (DDR) network being the two main biological processes in common in the two cell types. Further analyses of the DEGs with 2-fold or more changes between 30min repair and control group indicated that several cytokine signaling pathways were the most strongly affected in PS and DDR related pathways in RS, respectively. Gene ontology (GO) analyses directly showed differential biological process (BP) affected between PS and RS, with "regulation of transcription" being most overrepresented in PS and "cellular response to stress" in RS, respectively. Moreover, 374 DDR-related genes in PS and 158 in RS among all DEGs were filtered and clustered, which showed dynamic expression patterns in PS and RS. Our analyses provide a transcriptional landscape for male germ cells in response to MMS during spermatogenesis. PMID- 27720831 TI - Imaging flow cytometry in the assessment of leukocyte-platelet aggregates. AB - Platelets are subcellular blood elements with a well-established role in haemostasis. Upon activation platelets undergo granule exocytosis, resulting in alpha-granule P-Selectin being expressed on the cell membrane. This allows binding of activated platelets to P-Selectin glycoprotein ligand 1 (PSGL-1) expressing leukocytes, forming leukocyte-platelet aggregates (LPAs). Whole blood flow cytometry (FCM) has demonstrated that elevated circulating LPAs (especially monocyte LPAs) are linked to atherothrombosis in high risk patients, and that activated platelet binding influences monocytes towards a pro-adhesive and pro atherogenic phenotype. However, a limitation of conventional FCM is the potential for coincident events to resemble LPAs despite no tethering. Imaging cytometry can be used to characterize LPA formation and distinguish circulating MPAs from coincidental events. Platelets and leukocyte subsets are identified by expression of surface markers (e.g. the lipopolysachharide receptor CD14 on monocytes, glycoprotein Ib CD42b on platelets). In conventional FCM, all events with both leukocyte and platelet characteristics are designated as LPAs. However, by using an 'internal' mask based on the brightfield image and the fluorescent platelet identifier, imaging flow cytometry is able to distinguish leukocytes with tethered platelets (genuine LPAs) from leukocyte with coincidental, untethered platelets nearby. Mechanisms (e.g. adhesion molecules) or consequences (e.g. signal transduction) can then be separately analysed in platelet tethered and untethered leukocytes. Imaging flow cytometry therefore provides a more accurate approach for both enumeration and analysis of LPAs than conventional FCM.

PMID- 27720832 TI - Effects of renal sympathetic denervation on the stellate ganglion and brain stem in dogs. AB - BACKGROUND: Renal sympathetic denervation (RD) is a promising method of neuromodulation for the management of cardiac arrhythmia. OBJECTIVE: We tested the hypothesis that RD is antiarrhythmic in ambulatory dogs because it reduces the stellate ganglion nerve activity (SGNA) by remodeling the stellate ganglion (SG) and brain stem. METHODS: We implanted a radiotransmitter to record SGNA and electrocardiogram in 9 ambulatory dogs for 2 weeks, followed by a second surgery for RD and 2 months SGNA recording. Cell death was probed by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. RESULTS: Integrated SGNA at baseline and 1 and 2 months after RD were 14.0 +/- 4.0, 9.3 +/ 2.8, and 9.6 +/- 2.0 MUV, respectively (P = .042). The SG from RD but not normal control dogs (n = 5) showed confluent damage. An average of 41% +/- 10% and 40% +/- 16% of ganglion cells in the left and right SG, respectively, were TUNEL positive in RD dogs compared with 0% in controls dogs (P = .005 for both). The left and right SG from RD dogs had more tyrosine hydroxylase-negative ganglion cells than did the left SG of control dogs (P = .028 and P = .047, respectively). Extensive TUNEL-positive neurons and glial cells were also noted in the medulla, associated with strongly positive glial fibrillary acidic protein staining. The distribution was heterogeneous, with more cell death in the medial than lateral aspects of the medulla. CONCLUSION: Bilateral RD caused significant central and peripheral sympathetic nerve remodeling and reduced SGNA in ambulatory dogs. These findings may in part explain the antiarrhythmic effects of RD. PMID- 27720835 TI - Variation of fermentation redox potential during cell-recycling continuous ethanol operation. AB - Fermentation redox potential was monitored during cell-recycling continuous ethanol operation. The cell-recycling system (CRS) was operated using two hollow fibre (HF) membranes (pore sizes 0.20 and 0.65MUm) at three dilution rates (0.02, 0.04 and 0.08h-1). Saccharomyces cerevisiae NP 01 were recycled in the fermenter at a recycle ratio of 0.625. Aeration was provided at 2.5vvm for the first 4h and then further supplied continuously at 0.25vvm. As steady state was established, results showed that the fermentation redox potential was lower for processes employing CRS than those without. At the same dilution rates, the sugar utilization and ethanol production with CRS were higher than those without CRS. The highest fermentation efficiency (87.94g/l of ethanol, ~90% of theoretical yield) was achieved using a 0.2-MUm HF membrane CRS at a dilution rate of 0.02h 1. It was found that 7.53-10.07% of the carbon derived from glucose was incorporated into the yeast. Further, at the same dilution rates, yeast in the processes with CRS incorporated less carbon into ethanol than in those grown without CRS. This result suggests that processes involving CRS utilize more carbon for metabolite synthesis than biomass formation. This indicated that the processes with CRS could utilize more carbon for metabolite synthesis than biomass formation. PMID- 27720836 TI - Nitrosothiol formation and S-nitrosation signaling through nitric oxide synthases. AB - Nitric oxide (NO) is a gaseous signaling molecule impacting many biological pathways. NO is produced in mammals by three nitric oxide synthase (NOS) isoforms: neuronal (nNOS), endothelial (eNOS), and inducible (iNOS). nNOS and eNOS produce low concentrations of NO for paracrine signaling; NO produced and released from one cell diffuses to a neighboring cell where it binds and activates soluble guanylyl cyclase (sGC). iNOS produces high concentrations of NO using NO toxicity to amplify the innate immune response. Recent work has also defined protein cysteine S-nitrosation as a pathway of sGC-independent NO signaling. Though many studies have shown that S-nitrosation regulates the activity of NOS isoforms and other proteins in vivo, many issues need to be resolved to establish S-nitrosation as a viable signaling mechanism. Several chemical mechanisms result in S-nitrosation including transition metal-catalyzed pathways, NO oxidation followed by thiolate reaction, and thiyl radical recombination with NO. Once formed, nitrosothiols can be transferred between cellular cysteine residues via transnitrosation reactions. However, it is largely unclear how these chemical processes result in selective S-nitrosation of specific cellular cysteine residues. S-nitrosation site selectivity may be imparted via direct interactions or colocalization with NOS isoforms that focus chemical or transnitrosation mechanisms of nitrosothiol formation or transfer. Here, we discuss chemical mechanisms of nitrosothiol formation, S-nitrosation of NOS isoforms, and potential S-nitrosation signaling cascades resulting from NOS S nitrosation.

AB - A rapid separation of the ten nuclearly-encoded subunits of mitochondrial cytochrome c oxidase, and ten out of the eleven subunits of cytochrome bc1, was achieved using a short, 50 mm C18-reversed-phase column. The short column decreased the elution time 4-7 fold while maintaining the same resolution quality. Elution was similar to a previously published protocol, i.e., a water/acetonitrile elution gradient containing trifluoroacetic acid. Isolated subunits were identified by MALDI-TOF. The rapidity of the described method makes it extremely useful for determining the subunit composition of isolated mitochondrial complexes. The method can be used for both analytical and micro preparative purposes. PMID- 27720838 TI - Effectiveness of Elbasvir and Grazoprevir Combination, With or Without Ribavirin, for Treatment-Experienced Patients With Chronic Hepatitis C Infection. AB - BACKGROUND & AIMS: Patients infected with hepatitis C virus (HCV) genotype 1, 4, or 6, with or without cirrhosis, previously treated with peg-interferon and ribavirin, are a challenge to treat. We performed a phase 3 randomized controlled open-label trial to assess the effects of 12 or 16 weeks of treatment with once daily elbasvir (an HCV NS5A inhibitor, 50 mg) and grazoprevir (an HCV NS3/4A protease inhibitor, 100 mg), in a fixed-dose combination tablet, with or without twice-daily ribavirin, in this patient population. METHODS: We analyzed data from 420 patients (35% with cirrhosis, 64% with a null or partial response to peg interferon and ribavirin) who were randomly assigned (1:1:1:1) to groups given elbasvir and grazoprevir once daily, with or without twice-daily ribavirin, for 12 or 16 weeks, at 65 study centers in 15 countries in Europe, Asia, and Central and North America. Randomization was stratified by cirrhosis status and type of peg-interferon and ribavirin treatment failure. HCV RNA was measured using COBAS TaqMan v2.0. The primary end point was HCV RNA <15 IU/mL, 12 weeks after completion of treatment (SVR12). We aimed to determine whether the proportion of patients achieving an SVR12 in any group was greater than the reference rate (58%). RESULTS: With 12 weeks of treatment, an SVR12 was achieved by 92.4% of patients given elbasvir and grazoprevir and 94.2% of patients given elbasvir and grazoprevir with ribavirin. With 16 weeks of treatment, an SVR12 was achieved by 92.4% of patients given elbasvir and grazoprevir and 98.1% of patients given elbasvir and grazoprevir with ribavirin. Among patients treated for 12 weeks without ribavirin, virologic failure occurred in 6.8%, 0%, and 12.5% of patients with HCV genotype 1a, 1b, or 4 infection, respectively. Among patients given elbasvir and grazoprevir for 12 weeks, virologic failure occurred in 0% of patients infected with HCV genotypes 1 and 4 who relapsed after completing peg interferon and ribavirin, and 7.5% infected with HCV genotypes 1 and 4, respectively, with a null or partial response to peg-interferon and ribavirin. Among patients treated for 16 weeks who received ribavirin, there were no incidences of virologic failure. Common adverse events were fatigue (23.1%), headache (19.8%), and nausea (11.0%). CONCLUSIONS: The combination tablet of elbasvir and grazoprevir, with or without ribavirin, was highly efficacious in inducing an SVR12 in patients with HCV genotype 1, 4, or 6 infection failed by previous treatment with peg-interferon and ribavirin, including patients with cirrhosis and/or a prior null response. The treatment was generally well tolerated. ClinicalTrials.gov Number: NCT02105701. PMID- 27720841 TI - Linking gene regulation to cell behaviors in the posterior growth zone of sequentially segmenting arthropods. AB - Virtually all arthropods all arthropods add their body segments sequentially, one by one in an anterior to posterior progression. That process requires not only segment specification but typically growth and elongation. Here we review the functions of some of the key genes that regulate segmentation: Wnt, caudal, Notch pathway, and pair-rule genes, and discuss what can be inferred about their evolution. We focus on how these regulatory factors are integrated with growth and elongation and discuss the importance and challenges of baseline measures of growth and elongation. We emphasize a perspective that integrates the genetic regulation of segment patterning with the cellular mechanisms of growth and elongation. PMID- 27720840 TI - Management Strategies to Improve Outcomes of Patients With Inflammatory Bowel Diseases. AB - Strategies for management of inflammatory bowel diseases are shifting from simple control of symptoms toward full control of these diseases (clinical and endoscopic remission), with the final aim of blocking their progression and preventing bowel damage and disability. New goals have been proposed for treatment, such as treat to target and tight control based on therapeutic monitoring and early intervention. For patients who achieve clinical remission, there is often interest in discontinuation of therapy due to safety or economic concerns. We review the evidence supporting these emerging paradigms, the reasons that early effective treatment can alter progression of inflammatory bowel diseases, the importance of examining objective signs of inflammation, and the safety of reducing treatment dosage. We also discuss recent findings regarding personalization of care, including factors that predict patient outcomes and response to therapies, as well as preventative strategies. PMID- 27720842 TI - Redox sensitivity of the MyD88 immune signaling adapter. AB - The transcription factor nuclear factor-kappaB (NF-kappaB) mediates expression of key genes involved in innate immunity and inflammation. NF-kappaB activation has been repeatedly reported to be modulated by hydrogen peroxide (H2O2). Here, we show that the NF-kappaB-activating signaling adapter myeloid differentiation primary response gene 88 (MyD88) is highly sensitive to oxidation by H2O2 and may be redox-regulated in its function, thus facilitating an influence of H2O2 on the NF-kappaB signaling pathway. Upon oxidation, MyD88 forms distinct disulfide linked conjugates which are reduced by the MyD88-interacting oxidoreductase nucleoredoxin (Nrx). MyD88 cysteine residues functionally modulate MyD88 dependent NF-kappaB activation, suggesting a link between MyD88 thiol oxidation state and immune signaling. PMID- 27720843 TI - Hospital-Based Health Care After Traumatic Brain Injury. AB - OBJECTIVE: To investigate trends of hospital-based health care utilization after admission to a level I trauma center after acute traumatic brain injury (TBI). DESIGN: Retrospective review. SETTING: Large urban trauma hospital and a hospital council data registry consisting of 88 member institutions (>150 hospitals) covering 15,000 square miles. PARTICIPANTS: All patients (N=5291) admitted to a level I trauma center between January 1, 2006, and June 30, 2014, who experienced an acute TBI based on International Classification of Diseases, Ninth Revision coding. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Included the incidence and type of select hospital-based services received. Analyses were also categorized based on demographic and injury-related information. RESULTS: Of the 5291 patients with newly acquired TBI who were admitted, 512 died, leaving 4779 patients for inclusion in the final analysis. Additional health care utilization from January 1, 2006, and June 30, 2014, was recorded for 3158 patients (66%), totaling 12,307 encounters, with a median of 3 encounters (interquartile range, 1 5) and a maximum of 102 encounters. Most nonadmission urgent or procedural visits (96%) and inpatient encounters (93%) occurred in the first year. Of all the additional encounters, 9769 visits were nonadmission urgent or procedural visits (79%) with a median charge of $1955. The most common type of encounter was elective (46%), followed by medical emergency (29%). Of the remaining 2538 inpatient encounters (21%), the mean length of stay was 6 days with a median charge of $28,450. Medical emergency (39%) and elective admissions (33%) again were the most common encounter type. CONCLUSIONS: This analysis encompasses health care utilization across the range of TBI severity and numerous hospital systems, allowing for a more comprehensive and objective identification of reasons for readmission. This represents an initial step to developing a preventive intervention to manage secondary complications postinjury. PMID- 27720844 TI - Arogenate Dehydratase Isoforms Differentially Regulate Anthocyanin Biosynthesis in Arabidopsis thaliana. AB - Anthocyanins, a group of L-phenylalanine (Phe)-derived flavonoids, have been demonstrated to play important roles in plant stress resistance and interactions between plants and insects. Although the anthocyanin biosynthetic pathway and its regulatory mechanisms have been extensively studied, it remains unclear whether the level of Phe supply affects anthocyanin biosynthesis. Here, we investigated the roles of arogenate dehydratases (ADTs), the key enzymes that catalyze the conversion of arogenate into Phe, in sucrose-induced anthocyanin biosynthesis in Arabidopsis. Genetic analysis showed that all six ADT isoforms function redundantly in anthocyanin biosynthesis but have differential contributions. ADT2 contributes the most to anthocyanin accumulation, followed by ADT1 and ADT3, and ADT4-ADT6. We found that anthocyanin content is positively correlated with the levels of Phe and sucrose-induced ADT transcripts in seedlings. Consistently, addition of Phe to the medium could dramatically increase anthocyanin content in the wild-type plants and rescue the phenotype of the adt1 adt3 double mutant regarding the anthocyanin accumulation. Moreover, transgenic plants overexpressing ADT4, which appears to be less sensitive to Phe than overexpression of ADT2, hyperaccumulate Phe and produce elevated level of anthocyanins. Taken together, our results suggest that the level of Phe is an important regulatory factor for sustaining anthocyanin biosynthesis. PMID- 27720839 TI - Mechanisms, Management, and Treatment of Fibrosis in Patients With Inflammatory Bowel Diseases. AB - In the last 10 years, we have learned much about the pathogenesis, diagnosis, and management of intestinal fibrosis in patients with inflammatory bowel diseases. Just a decade ago, intestinal strictures were considered to be an inevitable consequence of long-term inflammation in patients who did not respond to anti inflammatory therapies. Inflammatory bowel diseases-associated fibrosis was seen as an irreversible process that frequently led to intestinal obstructions requiring surgical intervention. This paradigm has changed rapidly, due to the antifibrotic approaches that may become available. We review the mechanisms and diagnosis of this serious complication of inflammatory bowel diseases, as well as factors that predict its progression and management strategies. PMID- 27720845 TI - Identification of a gene expression signature in peripheral blood of multiple sclerosis patients treated with disease-modifying therapies. AB - Multiple Sclerosis (MS) is an inflammatory disease with neurodegenerative alterations, ultimately progressing to neurological handicap. Therapies are effective in counteracting inflammation but not neurodegeneration. Biomarkers predicting disease course or treatment response are lacking. We investigated whether altered gene and protein expression profiles were detectable in the peripheral blood of 78 relapsing remitting MS (RR-MS) patients treated by disease modifying therapies. A discovery/validation study on RR-MS responsive to glatiramer acetate identified 8 differentially expressed genes: ITGA2B, ITGB3, CD177, IGJ, IL5RA, MMP8, P2RY12, and S100beta. A longitudinal study on glatiramer acetate, Interferon-beta, or Fingolimod treated RR-MS patients confirmed that 7 out of 8 genes were downregulated with reference to the different therapies, whereas S100beta was always upregulated. Thus, we identified a peripheral gene signature associated with positive response in RR-MS which may also explain drug immunomodulatory effects. The usefulness of this signature as a biomarker needs confirmation on larger series of patients.

PMID- 27720847 TI - Extraction, characterization and evaluation of Kaempferia galanga L. (Zingiberaceae) rhizome extracts against acute and chronic inflammation in rats. AB - ETHNOPHARMACOLOGICAL RELEVANCE: The rhizomes of an acaulescent perennial herb, Kaempferia galanga Linn (Family: Zingiberaceae), used as traditional ayurvedic herb to get relief from indigestion, swelling, pain, high blood pressure and dyslipidemia. AIM OF THE STUDY: To prepare and characterize various extracts of Kaempferia galanga (K. galanga) for their comparative evaluation for the identification of the most efficacious extract and its possible pharmacological implication in acute and chronic inflammatory paradigm. MATERIALS AND METHODS: Dried and powdered rhizome of K. galanga was subjected to alcoholic extraction as well as successive extractions with various solvents. After phytochemical characterization, all the extracts were standardized for the presence of ethyl-p methoxycinnamate. The extracts, and the isolated compound, were tested against carrageenan-induced acute inflammation in rats. The most promising extract was tested against adjuvant-induced chronic inflammation in rats. Further, local myeloperoxidase (MPO) levels were investigated to establish the possible mechanism of action. RESULTS: Among the extracts, petroleum ether extract (SKG-1) and crude alcoholic extract (KG) had the maximum quantity of ethyl-p methoxycinnamate. SKG-1 (300mg/kg) was found effective against acute inflammation in rats. Further, SKG-1 (100mg/kg) reversed the inflammation and elevated MPO levels found in the chronic model. CONCLUSIONS: The results suggest that among all the extracts of K. galanga, SKG-1 effectively suppresses the progression of acute and chronic inflammation in rats by inhibition of neutrophil infiltration. PMID- 27720849 TI - Beneficial effect of commercial Rhodiola extract in rats with scopolamine-induced memory impairment on active avoidance. AB - : Rhodiola rosea L., family Crassulaceae also known as Golden Root or Arctic root is one of the most widely used medicinal plants with effect on cognitive dysfunction, psychological stress and depression. The aim of the study was to examine the effect of a standardized commercial Rhodiola extract on learning and memory processes in naive rats as well as its effects in rats with scopolamine induced memory impairment. MATERIALS AND METHODS: Sixty male Wistar rats were used in the study. The experiment was conducted in two series - on naive rats and on rats with scopolamine-induced model of impaired memory. The active avoidance test was performed in an automatic conventional shuttle box set-up. The criteria used were the number of conditional stimuli (avoidances), the number of unconditioned stimuli (escapes) as well as the number of intertrial crossings. RESULTS: The chemical fingerprinting of the standardized commercial Rhodiola extract was performed by means of nuclear magnetic resonance (NMR). Naive rats treated with standardized Rhodiola extract increased the number of avoidances during the learning session and memory retention test compared to the controls. Rats with scopolamine-induced memory impairment treated with Rhodiola extract showed an increase in the number of avoidances during the learning session and on the memory tests compared to the scopolamine group. The other two parameters were not changed in rats treated with the extract of Rhodiola in the two series. CONCLUSION: It was found that the studied Rhodiola extract exerts a beneficial effect on learning and memory processes in naive rats and rats with scopolamine induced memory impairment. The observed effect is probably due to multiple underlying mechanisms including its modulating effect on acetylcholine levels in the brain and MAO-inhibitory activity leading to stimulation of the monoamines' neurotransmission. In addition the pronounced stress-protective properties of Rhodiola rosea L. could also play a role in the improvement of cognitive functions. PMID- 27720848 TI - Evaluation of anti-hypertensive activity of Ulmus wallichiana extract and fraction in SHR, DOCA-salt- and L-NAME-induced hypertensive rats. AB - ETHNOPHARMACOLOGICAL RELEVANCE: Ulmus wallichiana Planchon (Himalayan Elm), a traditional medicinal plant, used in fracture healing in folk tradition of Uttarakhand, Himalaya, India. It is also used as diuretic. U. rhynchophylla, native to China, known as Gou Teng in Chinese medicine, is used for hypertension (WHO). U. macrocarpa has antihypertensive and vasorelaxant activity. However, no detailed studies related to hypertension have been reported previously, so we have explored the antihypertensive activity of U. wallichiana. AIM OF THE STUDY: To investigate the pharmacological effect of ethanolic extract (EE) and butanolic fraction (BF) of U. wallichiana in hypertensive rats. MATERIALS AND METHODS: SHR, DOCA-salt- and L-NAME-induced hypertension models were used. Treatment was performed by oral administration of EE and BF of U. wallichiana (500mg/kg/day and 50mg/kg/day) for 14 days. Then blood pressure was measured by non-invasive blood pressure (NIBP) measurement technique. Invasive blood pressure (IBP) was also reported to support the NIBP data. Concentrations of plasma renin, angiotensin II (Ang II), nitrate/nitrite (NO), cGMP were estimated. Angiotensin-converting enzyme (ACE) activity and ROS activity were also estimated. RESULTS: Blood pressure was significantly higher in SHR as compared to normotensive wistar group (170.59+/-0.83mmHg vs 121.54+/-1.24mmHg, respectively). SBP was increased in DOCA salt induced group compared to their control (132.77+/-3.90mmHg vs 107.85+/ 5.95mmHg, respectively) and L-NAME-induced group compared to their control (168.55+/-5.07mmHg vs 113.03+/-4.13mmHg, respectively). The treatment of extract and fraction of U. wallichiana significantly decreased the blood pressure in SHR+EE (151.26+/-1.85mmHg, p<0.001), SHR+BF (140.44+/-1.16mmHg, p<0.001); DOCA+EE (113.43+/-5.44mmHg, p<0.05), DOCA+BF (105.09+/-5.12mmHg, p<0.05) and L-NAME+EE (119.76+/-4.39mmHg, p<0.001), L-NAME+BF (117.50+/-7.27mmHg, p<0.001) compared to their respective diseased control groups. The plasma renin, Ang II and ACE activity were also significantly decreased and augmented the NO and cGMP levels. It also down regulated the expression of Renin, ACE, NOS3 and TGF-beta1 at mRNA levels. CONCLUSIONS: The EE and BF probably reducing the BP via Renin-angiotensin aldosterone system and NO/cGMP signaling pathway. The decrease in blood pressure may be due to presence of quercetin analogue flavonoids (2S,3S)-(+)-3',4',5,7 tetrahydroxydihydroflavonol-6-C-beta-D-glucopyranoside; 6-Glucopyranosyl 3,3',4',5,7-pentahydroxyflavone; 6-Glucopyranosyl-4',5,7-trihydroxyflavanone and (2S,3S)-(+)-4',5,7-trihydroxydihydroflavonol-6-C-beta-D-glucopyranoside, may be due to its antioxidant activity. Thus EE and BF of U. wallichiana found to have the potential ability to be used as herbal medicament to treat hypertension. PMID- 27720850 TI - An optimized protocol for adenosine triphosphate quantification in T lymphocytes of lymphopenic patients. AB - In several clinical contexts, the measurement of ATP concentration in T lymphocytes has been proposed as a biomarker of immune status, predictive of secondary infections. However, the use of such biomarker in lymphopenic patients requires some adaptations in the ATP dosage protocol. We used blood from healthy volunteers to determine the optimal experimental settings. We investigated technical aspects such as the type of anticoagulant for blood sampling, the effect of freeze and thaw cycles, the reagent and sample mixing sequence, and the optimal dilution buffer. We also shortened the incubation time to 8h, and even showed that a 30min incubation may be sufficient. To evaluate the ATP rise upon lymphocyte activation, the optimal dose of stimulant was defined to be 4MUg/mL of phytohaemagglutinin. Lastly, we determined that the number of T cells needed for this measurement was as low as 50,000, which is compatible with the existing lymphopenia in clinical settings. This optimized protocol appears ready to be assessed in lymphopenic patients to further investigate the interconnection between T lymphocyte metabolism and impaired phenotype and functions. PMID- 27720851 TI - Vaginal Extrusion of a Ventriculoperitoneal Shunt: A Case Report and Review of Literature. AB - BACKGROUND: Ventriculoperitoneal shunting is the most common treatment for hydrocephalus (excessive cerebrospinal fluid accumulation in the brain), but has the potential for serious complications such as shunt migration. Potential migration sites include the lateral ventricle mediastinum, gastrointestinal tract, abdominal wall, bladder, vagina, and scrotum. CASE: Here, we present a rare case of vaginal extrusion of a ventriculoperitoneal shunt. SUMMARY AND CONCLUSION: Neurosurgeons and gynecologists should be aware of the potential occurrence of this rare complication. PMID- 27720852 TI - Intermittent Nitrate Use and Risk of Hip Fracture. AB - PURPOSE: Nitrates, commonly used antianginal medications, also have a beneficial effect on bone remodeling and bone density, particularly with intermittent use. However, their effect on fracture risk is not clear. We examined the relation of short-acting nitrate use (proxy for intermittent use) with the risk of hip fracture in a large cohort of older adults with ischemic heart disease. METHODS: Participants aged 60 years or more with ischemic heart disease and without a history of hip fracture from The Health Improvement Network, an electronic medical records database in the United Kingdom, were included. The association of incident (new) use of short-acting nitrate formulations (nitroglycerin sublingual/spray/ointment or isosorbide dinitrate injection/sprays) with incident (new-onset) hip fracture risk was examined by plotting Kaplan-Maier curves and calculating hazard ratios using Cox proportional hazards regression models. Competing risk by death was analyzed in separate analyses. RESULTS: Among 14,451 pairs of matched nitrate users and nonusers (mean age, 72 +/- 7.6 years, 41% women for each cohort), 573 fractures occurred during follow-up (257 nitrate users; 316 nonusers). Hip fracture risk was 33% lower among short-acting nitrate users compared with nonusers (hazard ratio, 0.67; 95% confidence interval, 0.53 0.85; P = .0008). Competing risk analysis by death did not change effect estimates. CONCLUSIONS: In this large population-based cohort of older adults with ischemic heart disease, we found a significant reduction in hip fracture risk with the use of short-acting nitrates (intermittent use). Future studies are warranted given the potential for nitrates to be potent, inexpensive, and readily available antiosteoporotic agents. PMID- 27720853 TI - Association Between Gout and Aortic Stenosis. AB - BACKGROUND: An independent association between gout and coronary artery disease is well established. The relationship between gout and valvular heart disease, however, is unclear. The aim of this study was to assess the association between gout and aortic stenosis. METHODS: We performed a retrospective case-control study. Aortic stenosis cases were identified through a review of outpatient transthoracic echocardiography (TTE) reports. Age-matched controls were randomly selected from patients who had undergone TTE and did not have aortic stenosis. Charts were reviewed to identify diagnoses of gout and the earliest dates of gout and aortic stenosis diagnosis. RESULTS: Among 1085 patients who underwent TTE, 112 aortic stenosis cases were identified. Cases and nonaortic stenosis controls (n = 224) were similar in age and cardiovascular comorbidities. A history of gout was present in 21.4% (n = 24) of aortic stenosis subjects compared with 12.5% (n = 28) of controls (unadjusted odds ratio 1.90, 95% confidence interval 1.05-3.48, P = .038). Multivariate analysis retained significance only for gout (adjusted odds ratio 2.08, 95% confidence interval 1.00-4.32, P = .049). Among subjects with aortic stenosis and gout, gout diagnosis preceded aortic stenosis diagnosis by 5.8 +/- 1.6 years. The age at onset of aortic stenosis was similar among patients with and without gout (78.7 +/- 1.8 vs 75.8 +/- 1.0 years old, P = .16). CONCLUSIONS: Aortic stenosis patients had a markedly higher prevalence of precedent gout than age-matched controls. Whether gout is a marker of, or a risk factor for, the development of aortic stenosis remains uncertain. Studies investigating the potential role of gout in the pathophysiology of aortic stenosis are warranted and could have therapeutic implications. PMID- 27720854 TI - Neural correlates of judgments of learning - An ERP study on metacognition. AB - Metacognitive assessment of performance has been revealed to be one of the most powerful predictors of human learning success and academic achievement. Yet, little is known about the functional nature of cognitive processes supporting judgments of learning (JOLs). The present study investigated the neural underpinnings of JOLs, using event-related brain potentials. Participants were presented with picture pairs and instructed to learn these pairs. After each pair, participants received a task cue, which instructed them to make a JOL (the likelihood of remembering the target when only presented with the cue) or to make a control judgment. Results revealed that JOLs were accompanied by a positive slow wave over medial frontal areas and a bilateral negative slow wave over occipital areas between 350ms and 700ms following the task cue. The results are discussed with respect to recent accounts on the neural correlates of judgments of learning. PMID- 27720855 TI - Second-language learning effects on automaticity of speech processing of Japanese phonetic contrasts: An MEG study. AB - We examined discrimination of a second-language (L2) vowel duration contrast in English learners of Japanese (JP) with different amounts of experience using the magnetoencephalography mismatch field (MMF) component. Twelve L2 learners were tested before and after a second semester of college-level JP; half attended a regular rate course and half an accelerated course with more hours per week. Results showed no significant change in MMF for either the regular or accelerated learning group from beginning to end of the course. We also compared these groups against nine L2 learners who had completed four semesters of college-level JP. These 4-semester learners did not significantly differ from 2-semester learners, in that only a difference in hemisphere activation (interacting with time) between the two groups approached significance. These findings suggest that targeted training of L2 phonology may be necessary to allow for changes in processing of L2 speech contrasts at an early, automatic level. PMID- 27720856 TI - Sleep's role in the reconsolidation of declarative memories. AB - Sleep is known to support the consolidation of newly encoded and initially labile memories. Once consolidated, remote memories can return to a labile state upon reactivation and need to become reconsolidated in order to persist. Here we asked whether sleep also benefits the reconsolidation of remote memories after their reactivation and how reconsolidation during sleep compares to sleep-dependent consolidation processes. In three groups, participants were trained on a visuo spatial learning task in the presence of a contextual odor. Participants in the 'reconsolidation' group learned the task on day 1. On day 2, they were subjected to a reactivation procedure by presenting the odor cue and a mock recall test in the learning context before a 40-min sleep or wake period. Participants in the 'remote consolidation' group followed the same procedure but did not receive reactivation on day 2. Participants in the 'recent consolidation' group skipped the procedure on day 1 and learned the task immediately before the sleep or wake period. After the sleep or wake interval, memory stability was tested in all subjects. The results show that this short 40-min sleep period significantly facilitated the reconsolidation of reactivated memories, whereas the consolidation of non-reactivated remote memories was less affected and recently encoded memories did not benefit at all. These findings tentatively suggest that sleep has a beneficial effect on the reconsolidation of remote memories, acting at a faster rate than sleep-associated consolidation. PMID- 27720858 TI - Ocular parasitoses: A comprehensive review. AB - Parasitic infections of the eyes are a major cause of ocular diseases across the globe. The causative agents range from simple organisms such as unicellular protozoans to complex metazoan helminths. The disease spectrum varies depending on the geographic location, prevailing hygiene, living and eating habits of the inhabitants, and the type of animals that surround them. They cause enormous ocular morbidity and mortality not because they are untreatable, but largely due to late or misdiagnosis, often from unfamiliarity with the diseases produced. We provide an up-to-date comprehensive overview of the ophthalmic parasitoses. Each section describes the causative agent, mode of transmission, geographic distribution, ocular pathologies, and their management for common parasites with brief mention of the ones that are rare. PMID- 27720857 TI - Low protein to carbohydrate ratio diet delays onset of Parkinsonism like phenotype in Drosophila melanogaster parkin null mutants. AB - Dietary management plays a key role in the treatment of many diseases. However, no prospective studies have critically investigated the potential for dietary modification to delay the onset, or slow the progression, of Parkinson's Disease (PD). To study whether manipulating the Protein to Carbohydrate (P:C) ratio in the diet could affect the progression of PD, we compared Drosophila melanogaster parkin null mutants and their experimental controls fed with diets differing in their P:C ratio. We considered lifespan and feeding behaviors as well as motor and cellular functions on the 1:2 and 1:16 P:C diets. We observe that parkin mutants have a longer lifespan when fed the 1:16 P:C compared to those fed the 1:2 P:C diet. Parkin mutants fed the 1:16 P:C diet have delayed climbing deficit, increased resistance to starvation. Mutant flies fed the 1:16 P:C diet also have improved mitochondrial functions as evidenced by increased respiratory control ratio and mitochondrial membrane potential and decreased reactive oxygen species production and superoxide activity especially in old parkin mutants. Combined, these results suggest that dietary management has potential to delay the progression of PD. PMID- 27720859 TI - Involvement of P2X7 receptors in retinal ganglion cell apoptosis induced by activated Muller cells. AB - Muller cell reactivation (gliosis) is an early response in glaucomatous retina. Previous studies have demonstrated that activation of P2X7 receptors results in retinal ganglion cell (RGC) apoptosis. Here, the issues of whether and how activated Muller cells may contribute to RGC apoptosis through P2X7 receptors were investigated. Either intravitreal injection of (S)-3,5 dihydroxyphenylglycine (DHPG), a group I metabotropic glutamate receptor (mGluR I) agonist, in normal rat retinas, or DHPG treatment of purified cultured rat retinal Muller cells induced an increase in glial fibrillary acidic protein (GFAP) expression, indicative of Muller cell gliosis. In addition, an increase in adenosine triphosphate (ATP) release from purified cultured Muller cells was detected during DHPG treatment (for 10 min to 48 h), which was mediated by the intracellular mGluR5/Gq/PI-PLC/PKC signaling pathway. Intravitreal injection of DHPG mimicked the reduction in the number of fluorogold retrogradely labeled RGCs in chronic ocular hypertension (COH) rats. Treatment with the conditioned culture medium (CM) obtained from the DHPG-activated Muller cell medium induced an increase in the number of TUNEL-positive cells in cultured RGCs, which was mimicked by benzoylbenzoyl adenosine triphosphate (BzATP), a P2X7 receptor agonist, but was partially blocked by brilliant blue G (BBG), a P2X7 receptor antagonist. Moreover, the CM treatment of cultured RGCs significantly increased Bax protein level and decreased Bcl-2 protein level, which was also mimicked by BzATP and partially blocked by BBG, respectively. These results suggest that reactivated Muller cells may release excessive ATP, in turn leading to RGC apoptosis through activating P2X7 receptors in these cells. PMID- 27720861 TI - A Burkholderia sacchari cell factory: production of poly-3-hydroxybutyrate, xylitol and xylonic acid from xylose-rich sugar mixtures. AB - Efficient production of poly-3-hydroxybutyrate (P(3HB)) based on glucose-xylose mixtures simulating different types of lignocellulosic hydrolysate (LCH) was addressed using Burkholderia sacchari, a wild strain capable of metabolizing both sugars and producing P(3HB). Carbon catabolite repression was avoided by maintaining glucose concentration below 10g/L. Xylose concentrations above 30g/L were inhibitory for growth and production. In fed-batch cultivations, pulse size and feed addition rate were controlled in order to reach high productivities and efficient sugar consumptions. High xylose uptake and P(3HB) productivity were attained with glucose-rich mixtures (glucose/xylose ratio in the feed=1.5w/w) using high feeding rates, while with xylose-richer feeds (glucose/xylose=0.8w/w), a lower feeding rate is a robust strategy to avoid xylose build-up in the medium. Xylitol production was observed with xylose concentrations in the medium above 30 40g/L. With sugar mixtures featuring even lower glucose/xylose ratios, i.e. xylose-richer feeds (glucose/xylose=0.5), xylonic acid (a second byproduct) was produced. This is the first report of the ability of Burkholderia sacchari to produce both xylitol and xylonic acid. PMID- 27720860 TI - The adult zebrafish retina: In vivo optical sectioning with Confocal Scanning Laser Ophthalmoscopy and Spectral-Domain Optical Coherence Tomography. AB - Non-invasive imaging is an invaluable diagnostic tool in ophthalmology. Two imaging devices, the scanning laser ophthalmoscope (SLO) and spectral domain optical coherence tomography (SDOCT), emerged from the clinical realm to provide research scientists with a real-time view of ocular morphology in living animals. We utilized these two independent imaging modalities in a complementary manner to perform in vivo optical sectioning of the adult zebrafish retina. Due to the very high optical power of the zebrafish lens, the confocal depth of field is narrow, allowing for detailed en face views of specific retinal layers, including the cone mosaic. Moreover, we demonstrate that both native reflectance, as well as fluorescent features observed by SLO, can be combined with axial in-depth information obtained by SDOCT. These imaging approaches can be used to screen for ocular phenotypes and monitor retinal pathology in a non-invasive manner. PMID- 27720862 TI - Urinary incontinence in nulliparous women aged 25-64 years: a national survey. AB - BACKGROUND: A systematic survey of pelvic floor disorders in nulliparous women has not been presented previously. OBJECTIVE: The purpose of this study was to determine the prevalence of urinary incontinence parameters in a large cohort of nonpregnant, nulliparous women, and thereby construct a reference group for comparisons with parous women. STUDY DESIGN: This postal and World Wide Web-based questionnaire survey was conducted in 2014. The study population was identified from the Total Population Register in Sweden and comprised women who had not given birth and were aged 25-64 years. Four independent age-stratified, random samples comprising 20,000 women were obtained from the total number of eligible nullipara (n = 625,810). A 40-item questionnaire about pelvic floor symptoms, its severity, and its consequences were used. Age-dependent differences for various aspects of urinary incontinence were analyzed with the youngest group (25-34 years) serving as reference. Crude and body mass index-adjusted prevalence and its 95% confidence limits were calculated for each 10-year category. RESULTS: The response rate was 52% and the number of study participants was 9197. Urinary incontinence increased >5-fold from 9.7% in the youngest women with a body mass index <25 kg/m2 to 48.4% among the oldest women with a body mass index >=35 kg/m2. The prevalence of bothersome urinary incontinence almost tripled from 2.8 7.9% among all nulliparas. The proportion with bothersome urinary incontinence among incontinent women increased from 24.4% in the youngest age group to 32.3% in the age group 55-64 years. Nocturia >=2/night increased 4-fold to 17.0% and leakage >=1/wk increased 3-fold to 12.8% among the oldest women. Mixed urinary incontinence increased from 22.9-40.9% among the oldest 0-para with incontinence, whereas stress urinary incontinence decreased inversely from 43.6-33.0%. In the total cohort surgical treatment for urinary incontinence occurred in 3 per thousand. CONCLUSION: Almost every aspect of urinary incontinence was present in nulliparous women of all ages and prevalence increased with advancing age between 25-64 years. This must be taken into account when using nullipara as a control group in comparisons with parous women to estimate the effect of pregnancy and childbirth. PMID- 27720863 TI - Parity, weight change, and maternal risk of cardiovascular events. AB - BACKGROUND: High parity has been suggested to increase risk of maternal cardiovascular disease independent of body mass index measured after childbearing. Pregnancy is, however, associated with persistent weight gain and metabolic changes that, independent of parity, increase the risk of cardiovascular disease. It could therefore be questioned if high parity independently increases the risk of cardiovascular disease or if this association may be confounded, mediated, or modified by other parity-related factors. OBJECTIVE: We sought to investigate the association between parity and risk of cardiovascular disease, and secondary outcomes in terms of myocardial infarction and cerebral infarction, with particular focus on potential mediation by anthropometric measures and effect modification by lactation. STUDY DESIGN: We used data from 16,515 female participants (age 44.5-73.6 years) of the population based Malmo Diet and Cancer Study with baseline examination from 1991 through 1996. The Malmo Diet and Cancer Study was followed up throughout 2010, with a median follow-up of 15.8 years. We used Cox proportional hazards model to examine the association between parity and cardiovascular disease. RESULTS: Adjusted for age and other potential confounders, grand multiparous women (>=5 children) had an increased risk of cardiovascular disease (hazard ratio, 1.60; 95% confidence interval, 1.20-2.14), myocardial infarction (hazard ratio, 1.68; 95% confidence interval, 1.15-2.45), and cerebral infarction (hazard ratio, 1.74; 95% confidence interval, 1.18-2.58) compared to women with 2 children. Additional adjustment for baseline body mass index and weight change since age 20 years attenuated the risk, but the increased risk for cardiovascular disease (hazard ratio, 1.38; 95% confidence interval, 1.02-1.87) and myocardial infarction (hazard ratio, 1.53; 95% confidence interval, 1.04-2.26) in grand multiparous women remained significant. Models stratified by lactation time showed that risk was only raised in grand multiparous women who had a mean lactation time of <4 mo/child. In sensitivity analyses excluding women with a history of diabetes at baseline, risk estimates for grand multiparous women became nonsignificant in the full model. CONCLUSION: Part of the increased risk of cardiovascular disease and myocardial infarction in grand multiparous women seems to be mediated by weight gain and potentially by higher likelihood of type 2 diabetes mellitus. Lactation may modify the increased risk of grand multiparity in that longer duration might offset the cardiovascular disease risk. PMID- 27720864 TI - Application of cement on strategic vertebrae in the treatment of the osteoporotic spine. AB - BACKGROUND CONTEXT: The application of pedicle screws with cement to strengthen the fixation of the osteoporotic spine has increasingly gained popularity. However, the technique has also led to an increase in cement-related complications. PURPOSE: The aim of the present study was to compare the clinical and radiological results of the patients with degenerative spinal pathologies who were treated with pedicle screws and cement injections on all segments versus those who were treated with cement injections only on the strategic vertebrae selected. STUDY DESIGN: A retrospective clinical study. PATIENT SAMPLE: The sample consists of 31 patients who underwent spinal surgery due to degenerative spinal pathologies. OUTCOME MEASURES: Patients were assessed for the adequate spinal fusion and cement-related complication parameters. METHODS: Thirty-one patients with a minimum follow-up period of 2 years were divided into two groups and evaluated. Group A consisted of 17 patients (14 females, 3 males; mean age: 68.1 years) with cemented pedicle screws and Group B consisted of 14 patients (12 females, 2 males; mean age: 67.2 years) with cemented screws on selected vertebrae alone. Selection of the strategic vertebrae was made by taking the most stressed regions in the fusion site into account. Prophylactic vertebroplasty was performed in all patients in Group A and on strategic segments in Group B to avoid an adjacent segment fracture. Early- and late-term complications during the follow-up period were recorded. RESULTS: Mean follow-up period was 51.8 (range: 31 to 80) months in Group A and 41.2 (range: 26 to 61) months in Group B. Cemented pedicle screws were bilaterally placed on 94 vertebrae in Group A. In Group B, cement was applied on 28 of 80 vertebrae. Including the prophylactic vertebroplasties, a total of 111 cement applications were performed in Group A and 38 in Group B. Cement embolism, symptomatic chest discomfort, and duration of surgery were significantly higher in Group A (p<.05). No adjacent segment fracture in the proximal or distal vertebra, implant failure, or loss of correction was seen throughout the follow-up period. CONCLUSIONS: The application of cemented pedicle screws on all segments of the osteoporotic spine increases the cement volume and rate of cement-related complications. Cementing the strategic vertebrae alone will enhance the fixation strength and endurance and decrease the complications caused by cement application. PMID- 27720865 TI - Cytomegalovirus reactivation enhances the virulence of Staphylococcus aureus pneumonia in a mouse model. AB - OBJECTIVES: Cytomegalovirus (CMV) reactivation in intensive care unit patients may increase mortality and favour bacterial pneumonia. We developed a murine model to compare the severity of staphylococcal pneumonia after CMV reactivation and in CMV-negative mice. METHODS: Balb/c mice were primo-infected with murine cytomegalovirus (MCMV n=90) or received saline (control n=90). After latency, all mice underwent caecal ligation and puncture to trigger MCMV reactivation in MCMV primary-infected mice. Surviving animals received an intra-nasal inoculation with methicillin-susceptible Staphylococcus aureus (MSSA) to induce pneumonia. Mortality, lung bacterial count, histology and interferon-alpha and gamma serum levels were compared in MCMV reactivated and control mice 2, 5 and 15 days after pneumonia. RESULTS: After MSSA pneumonia, MCMV mice showed a trend towards a higher mortality (9.4% versus 0%; p 0.09) and a higher weight loss (2.2 (0.6-4.1 g) versus 0.7 (-0.3 to 1.3 g); p 0.005). The lung bacterial count was higher in MCMV mice 2 days (5*103 (103 to 3*105) versus 102 (0 to 4*102) CFU/lung; p 0.007) and 5 days (2.5*104 (1.6*104 to 6.5*105) versus 15 (10-40) CFU/lung; p 0.005) after MSSA pneumonia. 8/40 (20%) MCMV mice developed lung abscesses compared to 0% in control (p 0.011). Interferon-alpha serum levels 2 days after staphylococcal pneumonia were higher in MCMV mice. CONCLUSIONS: MCMV reactivation decreased lung bacterial clearance and favoured the development of staphylococcal abscessing pneumonia. CMV reactivation may be responsible for a higher susceptibility to bacterial sepsis. PMID- 27720866 TI - Morphological changes induced by beta-lactam antibiotics observed on Gram staining. PMID- 27720867 TI - The role of test-retest reliability in measuring individual and group differences in executive functioning. AB - BACKGROUND: Studies testing for individual or group differences in executive functioning can be compromised by unknown test-retest reliability. NEW METHOD: Test-retest reliabilities across an interval of about one week were obtained from performance in the antisaccade, flanker, Simon, and color-shape switching tasks. There is a general trade-off between the greater reliability of single mean RT measures, and the greater process purity of measures based on contrasts between mean RTs in two conditions. The individual differences in RT model recently developed by Miller and Ulrich was used to evaluate the trade-off. RESULTS: Test retest reliability was statistically significant for 11 of the 12 measures, but was of moderate size, at best, for the difference scores. The test-retest reliabilities for the Simon and flanker interference scores were lower than those for switching costs. COMPARISON WITH EXISTING METHODS: Standard practice evaluates the reliability of executive-functioning measures using split-half methods based on data obtained in a single day. Our test-retest measures of reliability are lower, especially for difference scores. These reliability measures must also take into account possible day effects that classical test theory assumes do not occur. CONCLUSIONS: Measures based on single mean RTs tend to have acceptable levels of reliability and convergent validity, but are "impure" measures of specific executive functions. The individual differences in RT model shows that the impurity problem is worse than typically assumed. However, the "purer" measures based on difference scores have low convergent validity that is partly caused by deficiencies in test-retest reliability. PMID- 27720868 TI - The use of the Emotional-Object Recognition as an assay to assess learning and memory associated to an aversive stimulus in rodents. AB - BACKGROUND: Emotionally salient experiences induce the formation of explicit memory traces, besides eliciting automatic or implicit emotional memory in rodents. This study aims at investigating the implementation of a novel task for studying the formation of limbic memory engrams as a result of the acquisition- and retrieval- of fear-conditioning - biased declarative memory traces, measured by animal discrimination of an "emotional-object". Moreover, by using this new method we investigated the potential interactions between stimulation of cannabinoid transmission and integration of emotional information and cognitive functioning. NEW METHOD: The Emotional-Object Recognition task is composed of 3 following sessions: habituation; cued fear-conditioned learning; emotional recognition. Rats are exposed to Context "B chamber" for habituation and cued fear-conditioning, and tested in Context "A chamber" for emotional-object recognition. RESULTS: Cued fear-conditioning induces a reduction in emotional object exploration time during the Emotional-Object Recognition task in controls. The activation of cannabinoid signalling impairs limbic memory formation, with respect to vehicle. COMPARISON TO EXISTING METHODS: The Emotional-Object Recognition test overcomes several limitations of commonly employed methods that explore declarative-, spatial memory and fear-conditioning in a non-integrated manner. It allows the assessment of unbiased cognitive indicators of emotional learning and memory. CONCLUSIONS: The Emotional-Object Recognition task is a valuable tool for investigating whether, and at what extent, specific drugs or pathological conditions that interfere with the individual affective/emotional homeostasis, can modulate the formation of emotionally salient explicit memory traces, thus jeopardizing control and regulation of animal behavioural strategy. PMID- 27720869 TI - Caffeic acid attenuated acetaminophen-induced hepatotoxicity by inhibiting ERK1/2 mediated early growth response-1 transcriptional activation. AB - Caffeic acid (CA) is a natural compound abundant in fruits, coffee and plants. This study aims to investigate the involved mechanism of the therapeutic detoxification of CA against acetaminophen (APAP)-induced hepatotoxicity. CA (10, 30 mg/kg) was orally given to mice at 1 h after mice were pre-administrated with APAP (300 mg/kg). The therapeutic detoxification of CA against APAP-induced hepatotoxicity was observed by detecting serum aminotransferases, liver malondialdehyde (MDA) amount and liver histological evaluation in vivo. CA reduced APAP-induced increase in the mRNA expression of early growth response 1 (Egr1) in hepatocytes, and inhibited APAP-induced Egr1 transcriptional activation in vitro and in vivo. CA reduced the increased expression of growth arrest and DNA-damage-inducible protein (Gadd45)alpha induced by APAP in hepatocytes. Moreover, Egr1 siRNA reduced Gadd45alpha expression and reversed APAP-induced cytotoxicity in hepatocytes. Further results showed that CA blocked APAP-induced activation of extracellular-regulated protein kinase (ERK1/2) signaling cascade in vivo and in vitro. In addition, the application of ERK1/2 inhibitors (PD98059 and U0126) abrogated the nuclear translocation of Egr1 induced by APAP in hepatocytes. In conclusion, this study demonstrated the therapeutic detoxification of CA against APAP-induced liver injury, and the inhibition of CA on ERK1/2-mediated Egr1 transcriptional activation was involved in this process. PMID- 27720870 TI - Achieving resistance specificity in prostate cancer. AB - Prostate (CaP) cancer is the second-leading cause of cancer-related mortality in men in Western societies. Androgen receptor (AR) signaling is a critical survival pathway for prostate cancer cells, and androgen-deprivation therapy (ADT) remains the principal treatment for patients with locally advanced and metastatic disease. Although a majority of patients initially respond to ADT, most will eventually develop castrate resistance. The recent discovery that AR signaling persists during systemic castration via intratumoral production of androgens led to the development of novel anti-androgen therapies. Although these therapies effectively palliate symptoms and prolong life, metastatic castration-resistant prostate cancer remains incurable. Recent studies suggest that epithelial plasticity, which covers a range of changes in differentiation and cell behavior, with full epithelial integrity at one end and epithelial-mesenchymal Transition (EMT) as the full realization of a plasticity is regulated by microRNAs (miRNAs). MicroRNAs are involved in human tumourigenesis and are aberrantly expressed in CaP cell lines, xenografts and clinical tissues and is associated with enhanced survival signaling, proliferation, migration, invasion, integrin-mediated adhesion, EMT, and drug resistance. Due to the oncogenic or tumor suppressive properties of CaP-related miRNAs, they are likely to be of clinical use as therapeutic targets for prostate cancer treatment in the near future. This review summarizes our current understanding of CaP and castration-recurrent CaP (CR-CaP) to earlier studies that characterized ADT and the molecular mechanisms that facilitate the transition from androgen-stimulated CaP to CR-CaP. PMID- 27720871 TI - Tunable doxorubicin release from polymer-gated multiwalled carbon nanotubes. AB - Two pH and temperature controlled drug delivery systems for cancer therapy are here reported by using vapour phase and liquid phase functionalized multiwalled carbon nanotubes (MWCNT). Both oxidized MWCNT were functionalized at the carboxyl groups with a short hydrophilic polyethylene glycol (PEG) chain. The nanosystems were loaded with doxorubicin and covered with the biocompatible polymer polylactide, able to form hydrogen bonding with PEG and to entrape the drug inside the two polymeric chains. The different oxidative reaction conditions of MWCNT have demonstrated to deeply affect their agglomeration ability and the available reactive surface area for drug loading which in turn, affected the drug release abilities of the synthesized polymer-gated drug delivery systems. The in vitro release abilities as well as their antiproliferative effect on three different human cancer cell lines were evaluated and compared, highlighting the possibility to tune the amount of drug released by controlling the functionalization degree of the carbon nanotube based material. Biological tests highlighted the high biocompatibility of both systems and their ability to deliver doxorubicin to cancer cells. PMID- 27720873 TI - Mechanisms of cellular uptake and endosomal escape of calcium-siRNA nanocomplexes. AB - Ca2+-siRNA nanocomplexes represent a simple yet an effective platform for siRNA delivery into the cell cytoplasm, with subsequent successful siRNA-induced target gene silencing. Herein, we aimed to elucidate the roles played by calcium ions in siRNA nanocomplex formation, cell uptake, and endosomal escape. We investigated whether the replacement of Ca2+in the nanocomplex by other bivalent cations would affect their cell entry and subsequent gene silencing. Our results indicate that Mg2+ and Ba2+ lead to the formation of nanocomplexes of similar physical features (size=100nm, surface charge zeta=-8mV) as the Ca2+-siRNA nanocomplexes. Yet, these nanocomplexes were not uptaken by the cells to the same extent as those prepared with Ca2+, and siRNA-induced target gene silencing was not obtained. Cell internalization of Ca2+--siRNA nanocomplexes, examined by employing chemical inhibitors to clathrin-, caveolin- and dynamin-mediated endocytosis pathways, indicated the involvement of all mechanisms in the process. Inhibition of endosome acidification by bafilomycin completely abolished the siRNA-mediated silencing by Ca2+-siRNA nanocomplexes. Collectively, our results indicate that Ca2+ promotes cell internalization and rapid endosomal escape, thus leading to the efficient siRNA-induced target gene silencing elicited by the Ca2+-siRNA nanocomplexes. PMID- 27720872 TI - LARETH-25 and beta-CD improve central transitivity and central pharmacological effect of the GLP-2 peptide. AB - Depression is a common mental disorder. More than 350 million people of all ages suffer from depression worldwide. Although a number of antidepressants are available, >20% of patients with major depressive disorder suffer from treatment resistant depression. Therefore, development of novel therapeutics to overcome this condition is required. We reported that intracerebroventricular administration of glucagon-like peptide-2 (GLP-2) exerts antidepressant-like effects treated with or without adrenocorticotropic hormone. In the present study, we developed a nasal formulation of GLP-2 containing 5% polyoxyethylene (25) lauryl ether and 1% beta-cyclodextrin that enhanced the resistance of GLP-2 to inactivation by dipeptidyl peptidase-4. Intranasal administration of this formulation (60MUg/kg) increased the delivery of GLP-2 to the brain and had antidepressant-like effects on rats. These results suggest the potential of the GLP-2 nasal formulation for use as a novel antidepressant. PMID- 27720875 TI - The effect of structurally related impurities on crystallinity reduction of sulfamethazine by grinding. AB - In this study, the effect of structurally related impurities on crystallinity reduction of sulfamethazine by grinding was evaluated. The crystallinity of sulfamethazine was not decreased when it was ground alone. However, when structurally related impurities with sulfonamide derivatives were blended, the crystallinity of sulfamethazine was decreased by grinding. Other materials without a sulfonamide moiety showed no such effect. The Raman spectra of sulfamethazine demonstrated that there was a difference between its crystalline and amorphous states within its sulfonamide structure. It was suggested that the sulfonamide structure of the impurities was important in causing the inhibition of recrystallization of sulfamethazine during grinding. PMID- 27720874 TI - Continuous production of itraconazole-based solid dispersions by hot melt extrusion: Preformulation, optimization and design space determination. AB - The purpose of this work was to increase the solubility and the dissolution rate of itraconazole, which was chosen as the model drug, by obtaining an amorphous solid dispersion by hot melt extrusion. Therefore, an initial preformulation study was conducted using differential scanning calorimetry, thermogravimetric analysis and Hansen's solubility parameters in order to find polymers which would have the ability to form amorphous solid dispersions with itraconazole. Afterwards, the four polymers namely Kollidon(r) VA64, Kollidon(r) 12PF, Affinisol(r) HPMC and Soluplus(r), that met the set criteria were used in hot melt extrusion along with 25wt.% of itraconazole. Differential scanning confirmed that all four polymers were able to amorphize itraconazole. A stability study was then conducted in order to see which polymer would keep itraconazole amorphous as long as possible. Soluplus(r) was chosen and, the formulation was fine-tuned by adding some excipients (AcDiSol(r), sodium bicarbonate and poloxamer) during the hot melt extrusion process in order to increase the release rate of itraconazole. In parallel, the range limits of the hot melt extrusion process parameters were determined. A design of experiment was performed within the previously defined ranges in order to optimize simultaneously the formulation and the process parameters. The optimal formulation was the one containing 2.5wt.% of AcDiSol(r) produced at 155 degrees C and 100rpm. When tested with a biphasic dissolution test, more than 80% of itraconazole was released in the organic phase after 8h. Moreover, this formulation showed the desired thermoformability value. From these results, the design space around the optimum was determined. It corresponds to the limits within which the process would give the optimized product. It was observed that a temperature between 155 and 170 degrees C allowed a high flexibility on the screw speed, from about 75 to 130rpm. PMID- 27720876 TI - ATR-FTIR spectroscopic imaging to study the drying and dissolution of pharmaceutical polymer-based films. AB - Pharmaceutical film dosage forms have recently become of interest to pharmaceutical formulation development, particularly for patients who experience difficulty in swallowing tablets or capsules. Furthermore, formulation scientists require a reliable analytical approach to reveal vital insight and investigate the drying process of these films to consolidate suitable quality control. Since most of the polymer-based films containing a drug are produced via solution or dispersion states, an estimation of the physicochemical properties of drugs during drying and dissolution is critical to design novel formulations with the consideration to control drug release, i.e. safety and efficacy to patients. This work presents the novel application of attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopic imaging to study the drying process and dissolution behaviour of polymer-based films. Two types of the ibuprofen containing films, hydroxypropyl methylcellusose (HPMC) based films for immediate release and polyvinylpyrrolidone (PVP) based films for extended release, were studied in modified pH environments and changing hydrophobicity. ATR-FTIR imaging has revealed important information on water ingress into the films and the presence, distribution, and physicochemical state of the drug. ATR-FTIR imaging is a powerful technique to investigate and to deeply understand physicochemical processes for pharmaceutical polymer-based films. PMID- 27720877 TI - Near-infrared chemical imaging (NIR-CI) of 3D printed pharmaceuticals. AB - Hot-melt extrusion and 3D printing are enabling manufacturing approaches for patient-centred medicinal products. Hot-melt extrusion is a flexible and continuously operating technique which is a crucial part of a typical processing cycle of printed medicines. In this work we use hot-melt extrusion for manufacturing of medicinal films containing indomethacin (IND) and polycaprolactone (PCL), extruded strands with nitrofurantoin monohydrate (NFMH) and poly (ethylene oxide) (PEO), and feedstocks for 3D printed dosage forms with nitrofurantoin anhydrate (NFAH), hydroxyapatite (HA) and poly (lactic acid) (PLA). These feedstocks were printed into a prototype solid dosage form using a desktop 3D printer. These model formulations were characterized using near infrared chemical imaging (NIR-CI) and, more specifically, the image analytical data were analysed using multivariate curve resolution-alternating least squares (MCR-ALS). The MCR-ALS algorithm predicted the spatial distribution of IND and PCL in the films with reasonable accuracy. In the extruded strands both the chemical mapping of the components in the formulation as well as the solid form of the active compound could be visualized. Based on the image information the total nitrofurantoin and PEO contents could be estimated., The dehydration of NFMH to NFAH, a process-induced solid form change, could be visualized as well. It was observed that the level of dehydration increased with increasing processing time (recirculation during the mixing phase of molten PEO and nitrofurantoin). Similar results were achieved in the 3D printed solid dosage forms produced from the extruded feedstocks. The results presented in this work clearly demonstrate that NIR-CI in combination with MCR-ALS can be used for chemical mapping of both active compound and excipients, as well as for visualization of solid form variation in the final product. The suggested NIR-CI approach is a promising process control tool for characterization of innovative patient-centred medicinal products. PMID- 27720878 TI - Theoretical modeling of actin-retrograde-flow passing clusters of confined T cell receptors. AB - Through the activation process of T cells, actin filaments move from the cell periphery toward the cell center. The moving filaments engage with T cell receptors and thus contribute to transportation of the signaling molecules. To study the connection between the moving actin filaments and T cell receptors, an experiment available in the literature has measured filaments flow velocity passing over a region of confined clusters of receptors. It shows that flow velocity decreases in the proximity of the receptors, and then regains its normal value after traversing the region, suggesting a dissipative friction-like connection. In this work, we develop a minimal theoretical model to re-examine this experiment. The model brings the insight that, in contrast to the first impression that the experiment gives, the direct necessity of having a minimum in the velocity profile is not the locally high friction region, but a combined driving force of push from upstream and pull from within and downstream of the system. The predicted driving force integrates our current understanding of the spatially dependent role of the myosin motor proteins and the actin polymerization-machinery, which make the pulling and pushing forces, respectively. PMID- 27720879 TI - Detrended cross-correlation coefficient: Application to predict apoptosis protein subcellular localization. AB - Apoptosis, or programed cell death, plays a central role in the development and homeostasis of an organism. Obtaining information on subcellular location of apoptosis proteins is very helpful for understanding the apoptosis mechanism. The prediction of subcellular localization of an apoptosis protein is still a challenging task, and existing methods mainly based on protein primary sequences. In this paper, we introduce a new position-specific scoring matrix (PSSM)-based method by using detrended cross-correlation (DCCA) coefficient of non-overlapping windows. Then a 190-dimensional (190D) feature vector is constructed on two widely used datasets: CL317 and ZD98, and support vector machine is adopted as classifier. To evaluate the proposed method, objective and rigorous jackknife cross-validation tests are performed on the two datasets. The results show that our approach offers a novel and reliable PSSM-based tool for prediction of apoptosis protein subcellular localization. PMID- 27720880 TI - Kinetics of the formation of a protein corona around nanoparticles. AB - Interaction of metal or oxide nanoparticles (NPs) with biological soft matter is one of the central phenomena in basic and applied biology-oriented nanoscience. Often, this interaction includes adsorption of suspended proteins on the NP surface, resulting in the formation of the protein corona around NPs. Structurally, the corona contains a "hard" monolayer shell directly contacting a NP and a more distant weakly associated "soft" shell. Chemically, the corona is typically composed of a mixture of distinct proteins. The corresponding experimental and theoretical studies have already clarified many aspects of the corona formation. The process is, however, complex, and its understanding is still incomplete. Herein, we present a kinetic mean-field model of the formation of the "hard" corona with emphasis on the role of (i) protein-diffusion limitations and (ii) interplay between competitive adsorption of distinct proteins and irreversible reconfiguration of their native structure. The former factor is demonstrated to be significant only in the very beginning of the corona formation. The latter factor is predicted to be more important. It may determine the composition of the corona on the time scales comparable or longer than a few hours. PMID- 27720881 TI - Bronchiectasis Severity Is an Independent Risk Factor for Vascular Disease in a Bronchiectasis Cohort. AB - BACKGROUND: Interest in the association of vascular disease with COPD and pneumonia has increased, but there is a lack of research in this area with patients with bronchiectasis. METHODS: A retrospective study of 400 patients attending a specialist bronchiectasis clinic in NHS Lothian (Edinburgh, UK) between May 2013 and September 2014 was conducted. The study assessed the prevalence of vascular disease (ischemic heart disease, cerebrovascular disease, peripheral vascular disease, and atrial fibrillation). Using multivariable models, independent risk factors were identified for vascular disease that developed following the diagnosis of bronchiectasis. RESULTS: The study included 400 patients. There was preexisting vascular disease (ie, before the diagnosis of bronchiectasis) in 44 patients (11%), and vascular disease occurred after the diagnosis of bronchiectasis after a mean of 9.4 years (95% CI, 6.0-12.8 years) in 45 patients (11%). Independent factors associated with all-cause vascular disease after the diagnosis of bronchiectasis included male sex, hypertension, receiving long-term statin therapy, and having moderate-severity bronchiectasis or worse. CONCLUSIONS: In conclusion, bronchiectasis severity is independently associated with the development of vascular disease after the diagnosis of bronchiectasis. Future studies addressing the impact of primary and secondary prevention are warranted. PMID- 27720884 TI - Histopathological subgroups in knee osteoarthritis. AB - OBJECTIVE: Osteoarthritis (OA) is a heterogeneous, multi-tissue disease. We hypothesised that different histopathological features characterise different stages during knee OA progression, and that discrete subgroups can be defined based on validated measures of OA histopathological features. DESIGN: Medial tibial plateaux and synovium were from 343 post-mortem (PM) and 143 OA arthroplasty donations. A 'chondropathy/osteophyte' group (n = 217) was classified as PM cases with osteophytes or macroscopic medial tibiofemoral chondropathy lesions >=grade 3 to represent pre-surgical (early) OA. 'Non arthritic' controls (n = 48) were identified from the remaining PM cases. Mankin histopathological scores were subjected to Rasch analysis and supplemented with histopathological scores for subchondral bone marrow replacement and synovitis. Item weightings were derived by principle components analysis (PCA). Histopathological subgroups were sought using latent class analysis (LCA). RESULTS: Chondropathy, synovitis and osteochondral pathology were each associated with OA at arthroplasty, but each was also identified in some 'non-arthritic' controls. Tidemark breaching in the chondropathy/osteophyte group was greater than in non-arthritic controls. Three histopathological subgroups were identified, characterised as 'mild OA', or 'severe OA' with mild or moderate/severe synovitis. CONCLUSIONS: Presence and severity of synovitis helps define distinct histopathological OA subgroups. The absence of a discrete 'normal' subgroup indicates a pathological continuum between normality and OA status. Identifying specific pathological processes and their clinical correlates in OA subgroups has potential to accelerate the development of more effective therapies. PMID- 27720882 TI - Association Between Insomnia and Asthma Burden in the Severe Asthma Research Program (SARP) III. AB - BACKGROUND: Sleep difficulties are commonly reported by patients with asthma; however, the prevalence of insomnia and its association with disease burden and well-being is unknown. We aimed to determine the prevalence of insomnia, defined as combined sleep-specific complaints with associated daytime symptoms, among a large sample of adults with asthma, and to compare well-being, asthma control, and asthma-related health care utilization in individuals with asthma and insomnia and those without insomnia. METHODS: Baseline data from adults with physician-confirmed asthma enrolled in the Severe Asthma Research Program III was used for analyses (N = 714). Participants completed the Insomnia Severity Index (ISI), Asthma Control Test, Asthma Quality of Life Questionnaire, and Hospital Anxiety and Depression Scale. RESULTS: Insomnia (ISI >= 10) was identified in 263 participants (37%). Presence of insomnia was associated with higher levels of depression and anxiety symptoms and poorer quality of life. Those with insomnia had a 2.4-fold increased risk for having not well-controlled asthma and a 1.5 fold increased risk for asthma-related health care utilization in the past year compared with those without insomnia. CONCLUSIONS: Insomnia is highly prevalent in asthma and is associated with adverse outcomes. Further studies are needed to gain a better understanding of the interaction between insomnia and asthma control. PMID- 27720883 TI - Pediatric OSA Syndrome Morbidity Biomarkers: The Hunt Is Finally On! AB - Since initial reports 40 years ago on pediatric OSA syndrome (OSAS) as a distinct and prevalent clinical entity, substantial advances have occurred in the delineation of diagnostic and treatment approaches. However, despite emerging and compelling evidence that OSAS increases the risk for cognitive, cardiovascular, and metabolic end-organ morbidities, routine assessment of such morbidities is seldom conducted in clinical practice. One of the major reasons for such discrepancies resides in the relatively labor-intensive and onerous steps that would be required to detect the presence of any of such morbidities, further adding to the already elevated cost of diagnosing the disorder. To circumvent these obstacles, the search for biomarker signatures of pediatric OSA and its cognitive and cardiometabolic consequences was launched, and considerable progress has occurred since then. Here, we review the current evidence for the presence of morbidity-related biomarkers among children with OSAS, and explore future opportunities in this promising arena. PMID- 27720886 TI - Maternal cortical response to baby pain and postpartum depressive symptoms. AB - Decreased maternal empathic abilities toward infants have been reported with postpartum depression (PPD). The aims of this study were: (1) To identify mothers' cortical regions activated by the observation of their own newborn's pain; (2) To study the relation between such cortical activation and PPD symptoms. By optical topography, a functional neuroimaging system, we assessed mothers' cortical activation when watching their own newborns during a heel prick. PPD symptoms and newborn's pain expression were also assessed. Watching their newborn in pain activated mothers' left somatosensory cortex (P=0.003) and right superior temporal cortex (P=0.002). PPD score showed a negative correlation with left somatosensory cortex activation (rs=-0.41; P=0.026), that decreased as PPD symptoms increased. To conclude, an activation of cortical areas, previously associated with empathy for pain, can be demonstrated in the mother shortly after birth. Such response appeared to be dampened by PPD symptoms. PMID- 27720885 TI - C57BL/6 mice are resistant to joint degeneration induced by whole-body vibration. AB - OBJECTIVE: Whole-body vibration (WBV) platforms are commercially available devices that are used clinically to treat numerous musculoskeletal conditions based on their reported ability to increase bone mineral density and muscle strength. Despite widespread use, there is an alarming lack of understanding of the direct effects of WBV on joint health. Previous work by our lab demonstrated that repeated exposure to WBV using protocols that model those used clinically, induces intervertebral disc (IVD) degeneration and osteoarthritis-like damage in the knee of skeletally mature, male mice of a single outbred strain (CD-1). The present study examined whether exposure to WBV induces similar deleterious effects in a genetically different strain of mouse (C57BL/6). DESIGN: Male 10 week-old C57BL/6 mice were exposed to vertical sinusoidal WBV for 30 min/day, 5 days/week, for 4 or 8 weeks using previously reported protocols (45 Hz, 0.3 g peak acceleration). Following WBV, joint tissues were examined using histological analysis and gene expression was quantified using real-time PCR (qPCR). RESULTS: Our analyses show a lack of WBV-induced degeneration in either the knee or IVDs of C57BL/6 mice exposed to WBV for 4 or 8 weeks, in direct contrast to the WBV induced damage previously reported by our lab in CD-1 mice. CONCLUSIONS: Together with previous studies from our group, the present study demonstrates that the effects of WBV on joint tissues vary in a strain-specific manner. These findings highlight the need to examine genetic or physiological differences that may underlie susceptibility to the deleterious effects of WBV on joint tissues.

PMID- 27720889 TI - Molecular evolution and phylogenetic analysis of biocontrol genes acquired from SCoT polymorphism of mycoparasitic Trichoderma koningii inhibiting phytopathogen Rhizoctonia solani Kuhn. AB - The biocontrol agent Trichoderma (T. harzianum, T. viride, T. virens, T. hamantum, T. koningii, T. pseudokoningii and Trichoderma species) inhibited variably (15.32 - 88.12%) the in vitro growth of Rhizoctonia solani causing root rot in cotton. The T. koningii MTCC 796 evidenced highest (88.12%) growth inhibition of test pathogen followed by T. viride NBAII Tv23 (85.34%). Scanning electron microscopic study confirmed mycoparasitism for MTCC 796 and Tv23 which were capable of completely overgrowing on R. solani by degrading mycelia, coiling around the hyphae with hook-like structures. The antagonists T. harzianum NBAII Th1 and, T. virens NBAII Tvs12 exhibited strong antibiosis and formed 2-4 mm zone of inhibition for 70.28% and 46.62%, respectively growth inhibition of test pathogen. Mycoparasitism is a strong mode of action for biocontrol activity compared with antibiosis. The antagonists Trichoderma strains were performed for start codon targeted (SCoT) polymorphism to acquire biocontrol genes from potent antagonist. The six unique SCoT fragments amplified by genomic DNA of best mycoparasitic antagonist MTCC 796 strain are subjected to DNA sequencing resulted to confirm two functional sequences for activity related to biocontrol genes. The phylogenetic and molecular evolution of functional 824 bp of SCoT-3(920) and 776 bp of SCoT-6(806) fragments signify sequence homology with biocontrol genes endochitinase (partial cds of 203 amino acids) and novel hmgR genes (partial cds of 239 amino acids), respectively and the same were annotated and deposited in NCBI GenBank database. The hmgR gene is liable to be express hmg - CoA reductase which is a key enzyme for regulation of terpene biosynthesis and mycoparasitic strains produced triterpenes during antagonism to inhibit growth of fungal pathogen as evidenced with GC-MS profile. The biocontrol genes are found in best antagonist T. koningii MTCC 796 for mycoparasitic activity to restrain the growth of test pathogen R. solani. PMID- 27720890 TI - SIRT1 overexpression in cervical squamous intraepithelial lesions and invasive squamous cell carcinoma. AB - Invasive squamous cell carcinoma (SCC) of the cervix involves the progression of premalignant cervical intraepithelial neoplasia (CIN) and is associated with persistent human papillomavirus infection. Most CINs will regress, and the challenge is to identify the lesions likely to progress to invasive cancer. We evaluated Sirtuin 1 (SIRT1) expression in nonneoplastic cervix, CINs, and SCCs as a potential biomarker to predict disease progression. A total of 101 cases were selected including 29 CIN 1s, 32 CIN 2s, 16 CIN 3s, 2 microinvasive SCCs, and 22 invasive SCCs. Cervical nonneoplastic squamous epithelium showed weak positivity of SIRT1 in the basal layer. SIRT1 cytoplasmic overexpression was found in 13.8% of CIN 1s (4/29), 40.6% of CIN 2s (13/32), and 50% of CIN 3s (8/16), and it was statistically significant between CIN 1 and CIN 2/3 lesions (P=.01). All 24 cases of invasive and microinvasive SCC showed SIRT1 overexpression, with 25% (6/24) showing cytoplasmic staining only, 4.2% (1/24) showing nuclear staining only, and 70.8% (17/24) showing both nuclear and cytoplasmic staining. From CIN 1 to SCC, SIRT1 expression showed steady and statistically significant increase (CIN 1 versus CIN 2-3, P=.01; CIN 2-3 versus SCC, P=.0001). Thus, SIRT1 may serve as a potential biomarker for predicting the progression of CIN to invasive SCC. PMID- 27720891 TI - Effects of competition outcome on testosterone concentrations in humans: An updated meta-analysis. AB - A contribution to a special issue on Hormones and Human Competition. Since Archer's (2006) influential meta-analysis, there has been a major increase in the number of studies investigating the effect of competition outcome on testosterone reactivity patterns in humans. Despite this increased research output, there remains debate as to whether competition outcome modulates testosterone concentrations. The present paper examines this question using a meta-analytic approach including papers published over the last 35years. Moreover, it provides the first meta-analytic estimate of the effect of competition outcome on testosterone concentrations in women. Results from a meta-analysis involving 60 effect sizes and >2500 participants indicated that winners of a competition demonstrated a larger increase in testosterone concentrations relative to losers (D=0.20)-an effect that was highly heterogeneous. This 'winner-loser' effect was most robust in studies conducted outside the lab (e.g., in sport venues) (D=0.43); for studies conducted in the lab, the effect of competition outcome on testosterone reactivity patterns was relatively weak (D=0.08), and only found in studies of men (D=0.15; in women: D=-0.04). Further, the 'winner-loser' effect was stronger among studies in which pre-competition testosterone was sampled earlier than (D=0.38, after trim and fill correction) rather than within (D=0.09) 10min of the start of the competition. Therefore, these results also provide important insight regarding study design and methodology, and will be a valuable resource for researchers conducting subsequent studies on the 'winner loser' effect. PMID- 27720892 TI - Carbon monoxide releasing molecule induces endothelial nitric oxide synthase activation through a calcium and phosphatidylinositol 3-kinase/Akt mechanism. AB - The production of nitric oxide (NO) by endothelial NO synthase (eNOS) plays a major role in maintaining vascular homeostasis. This study elucidated the potential role of carbon monoxide (CO)-releasing molecules (CORMs) in NO production and explored the underlying mechanisms in endothelial cells. We observed that 25MUM CORM-2 could increase NO production and stimulate an increase in the intracellular Ca2+ level. Furthermore, ethylene glycol-bis(beta-aminoethyl ether)-N,N,N',N'-tetra acetic acid caused CORM-2-induced NO production, which was abolished by 1,2-bis(2-aminophenoxy) ethane-N,N,N',N'-tetraacetic acid tetraacetoxy-methyl ester (BAPTA-AM), indicating that intracellular Ca2+ release plays a major role in eNOS activation. The inhibition of the IP3 receptor diminished the CORM-2-induced intracellular Ca2+ increase and NO production. Furthermore, CORM-2 induced eNOS Ser1179 phosphorylation and eNOS dimerization, but it did not alter eNOS expression. CORM-2 (25MUM) also prolonged Akt phosphorylation, lasting for at least 12h. Pretreatment with phosphatidylinositol 3-kinase inhibitors (wortmannin or LY294002) inhibited the increases in NO production and phosphorylation but did not affect eNOS dimerization. CORM-2 induced eNOS Ser1179 phosphorylation was intracellularly calcium-dependent, because pretreatment with an intracellular Ca2+ chelator (BAPTA-AM) inhibited this process. Although CORM-2 increases intracellular reactive oxygen species (ROS), pretreatment with antioxidant enzyme catalase and N-acetyl-cysteine did not abolish the CORM-2-induced eNOS activity or phosphorylation, signifying that ROS is not involved in this activity. Hence, CORM-2 enhances eNOS activation through intracellular calcium release, Akt phosphorylation, and eNOS dimerization. PMID- 27720893 TI - Aerobic exercise-related attenuation of arterial pulmonary hypertension: A right arrow targets the disease? AB - Characterized by progressive elevation of mean pulmonary artery pressure and pulmonary vascular resistance, pulmonary arterial hypertension (PAH) is an important health problem that contributes to right heart failure. Pulmonary arterial remodeling and constriction are two prominent features of PAH. It is a traditional view that increasing pulmonary blood flow and pressure, aerobic exercise does more harm than good to the pulmonary vasculature in PAH. However, recent studies have documented a potential benefit of low-intensity aerobic exercise for PAH patients. Here the current mini-review outlines the evidence and challenges for this additional tool in our armamentarium to combat this ominous disease. PMID- 27720895 TI - Stem cells and their role in pituitary tumorigenesis. AB - The presence of adult pituitary stem cells (PSCs) has been described in murine systems by comprehensive cellular profiling and genetic lineage tracing experiments. PSCs are thought to maintain multipotent capacity throughout life and give rise to all hormone-producing cell lineages, playing a role in pituitary gland homeostasis. Additionally, PSCs have been proposed to play a role in pituitary tumorigenesis, in both adenomas and adamantinomatous craniopharyngiomas. In this manuscript, we discuss the different approaches used to demonstrate the presence of PSCs in the murine adult pituitary, from marker analyses to genetic tracing. In addition, we review the published literature suggesting the existence of tumor stem cells in mouse and human pituitary tumors. Finally, we discuss the potential role of PSCs in pituitary tumorigenesis in the context of current models of carcinogenesis and present evidence showing that in contrast to pituitary adenoma, which follows a classical cancer stem cell paradigm, a novel mechanism has been revealed for paracrine, non-cell autonomous tumor initiation in adamantinomatous craniopharyngioma, a benign but clinically aggressive pediatric tumor. PMID- 27720896 TI - Genetic programs of the developing tuberal hypothalamus and potential mechanisms of their disruption by environmental factors. AB - The hypothalamus is a critical regulator of body homeostasis, influencing the autonomic nervous system and releasing trophic hormones to modulate the endocrine system. The developmental mechanisms that govern formation of the mature hypothalamus are becoming increasingly understood as research in this area grows, leading us to gain appreciation for how these developmental programs are susceptible to disruption by maternal exposure to endocrine disrupting chemicals or other environmental factors in utero. These vulnerabilities, combined with the prominent roles of the various hypothalamic nuclei in regulating appetite, reproductive behaviour, mood, and other physiologies, create a window whereby early developmental disruption can have potent long-term effects. Here we broadly outline our current understanding of hypothalamic development, with a particular focus on the tuberal hypothalamus, including what is know about nuclear coalescing and maturation. We finish by discussing how exposure to environmental or maternally-derived factors can perhaps disrupt these hypothalamic developmental programs, and potentially lead to neuroendocrine disease states. PMID- 27720894 TI - Melanoma antigen-A11 regulates substrate-specificity of Skp2-mediated protein degradation. AB - Melanoma antigen-A11 (MAGE-A11) is a proto-oncogene involved in androgen receptor signaling and androgen-dependent cell growth. In this report we provide evidence that MAGE-A11 interacts with Skp2 (S phase kinase-associated protein), the substrate recognition protein of the Skp1-Cullin1-F-box E3 ubiquitin ligase, and with Skp2 binding protein, cyclin A. A similar cyclin A binding motif in MAGE-A11 and Skp2 was consistent with a competitive relationship between MAGE-A11 and Skp2 in binding cyclin A. Skp2 inhibited MAGE-A11 interaction with cyclin A. Differential effects of MAGE-A11 on Skp2-mediated protein degradation were also revealed. MAGE-A11 increased Skp2-mediated degradation of cyclin A and retinoblastoma-related protein p130. In contrast, MAGE-A11 decreased Skp2 mediated degradation of E2F1 and Skp2 self-ubiquitination. Stabilization of E2F1 by MAGE-A11 was associated with sequestration and inactivation of Skp2 through the formation of an E2F1-MAGE-A11-Skp2 complex. We conclude that direct interactions of MAGE-A11 with Skp2 and cyclin A regulate the substrate specificity of Skp2-mediated protein degradation. PMID- 27720897 TI - Cell type-specific and common characteristics of exosomes derived from mouse cell lines: Yield, physicochemical properties, and pharmacokinetics. AB - Exosomes are small membrane vesicles secreted from cells and are expected to be used as drug delivery systems. Important characteristics of exosomes, such as yield, physicochemical properties, and pharmacokinetics, may be different among different cell types. However, there is limited information about the effect of cell type on these characteristics. In the present study, we evaluated these characteristics of exosomes derived from five different types of mouse cell lines: B16BL6 murine melanoma cells, C2C12 murine myoblast cells, NIH3T3 murine fibroblasts cells, MAEC murine aortic endothelial cells, and RAW264.7 murine macrophage-like cells. Exosomes were collected using a differential ultracentrifugation method. The exosomes collected from all the cell types were negatively charged globular vesicles with a diameter of approximately 100nm. C2C12 and RAW264.7 cells produced more exosomes than the other types of cells. The exosomes were labeled with a fusion protein of Gaussia luciferase and lactadherin to evaluate their pharmacokinetics. After intravenous injection into mice, all the exosomes rapidly disappeared from the systemic circulation and mainly distributed to the liver. In conclusion, the exosome yield was significantly different among the cell types, and all the exosomes evaluated in this study showed comparable physicochemical and pharmacokinetic properties. PMID- 27720898 TI - The isolated perfused human skin flap model: A missing link in skin penetration studies? AB - Development of effective (trans)dermal drug delivery systems requires reliable skin models to evaluate skin drug penetration. The isolated perfused human skin flap remains metabolically active tissue for up to 6h during in vitro perfusion. We introduce the isolated perfused human skin flap as a close-to-in vivo skin penetration model. To validate the model's ability to evaluate skin drug penetration the solutions of a hydrophilic (calcein) and a lipophilic (rhodamine) fluorescence marker were applied. The skin flaps were perfused with modified Krebs-Henseleit buffer (pH7.4). Infrared technology was used to monitor perfusion and to select a well-perfused skin area for administration of the markers. Flap perfusion and physiological parameters were maintained constant during the 6h experiments and the amount of markers in the perfusate was determined. Calcein was detected in the perfusate, whereas rhodamine was not detectable. Confocal images of skin cross-sections shoved that calcein was uniformly distributed through the skin, whereas rhodamine accumulated in the stratum corneum. For comparison, the penetration of both markers was evaluated on ex vivo human skin, pig skin and cellophane membrane. The proposed perfused flap model enabled us to distinguish between the penetrations of the two markers and could be a promising close-to-in vivo tool in skin penetration studies and optimization of formulations destined for skin administration. PMID- 27720899 TI - Identification of novel peptides against TNF-alpha using phage display technique and in silico modeling of their modes of binding. AB - The aim of this study was to identify novel TNF-alpha blocking peptide(s) using phage display technology. Two novel 7-mer TNF-alpha binding peptides P51 and P52 with Kd values of 1.47 and 0.51nM were identified. Phage particles displaying P51 and P52 peptides at 0.318nM concentration prevent cytotoxic effect of TNF-alpha on L929 cells by 8.2% and 16.15%, respectively. Synthesized P51 and P52 peptides also inhibited TNF-alpha induced cytotoxicity with IC50 values of 25.15+/-2.18 and 7.08+/-2.24MUM, respectively. The result of RT-PCR also supports the inhibitory activity of the identified peptides, where P51 and P52 significantly inhibit the inductive effect of TNF-alpha on IkappaB-alpha mRNA levels. The inhibitory effects of the peptides were attributed to their abilities of binding at the inter-subunit interfaces leading to TNF-alpha dissociation. The results of molecular docking studies revealed that the peptides-TNF-alpha complexes are mostly stabilized by hydrophobic contacts. PMID- 27720900 TI - Robust at-line quantification of poly(3-hydroxyalkanoate) biosynthesis by flow cytometry using a BODIPY 493/503-SYTO 62 double-staining. AB - Poly(3-hydroxyalkanoates) (PHAs) are bio-based and biodegradable polyesters which have been considered as a promising alternative to petrol-based plastics. Their bacterial production is a dynamic process in which intracellular polymerization and depolymerization are closely linked and depend on the availability of carbon substrates and other nutrients. These dynamics require a fast and quantitative method to determine the optimal harvest-time of PHA containing cells or to adjust carbon supply. In principle, flow cytometry (FCM) is an ideal tool that suits these requirements and, in addition, provides data on the PHA content of different cell populations. However, FCM-based PHA quantification methods have often relied on laborious sample preparation including washing steps and long incubation times. Here, we introduce a fast method based on double-staining using BODIPY 493/503 for PHA staining and SYTO 62 for DNA that allows acquiring reliable fluorescence and cell count data in <10min. Finally, fed-batch experiments with Pseudomonas putida KT2440 and Rhodospirillum rubrum S1 revealed that the method was robust and independent of the strain and type of PHA (medium chain-length [mcl-] and short-chain-length [scl-] PHA, respectively). Interestingly, the specific PHA fluorescence was in case of mcl-PHA larger than for scl-PHA, probably reflecting the different material properties (e.g., specific density, hydrophilicity and crystallinity). PMID- 27720901 TI - Guarana (Paullinia cupana) ameliorates memory impairment and modulates acetylcholinesterase activity in Poloxamer-407-induced hyperlipidemia in rat brain. AB - Hyperlipidemia is a risk factor for the development of cognitive dysfunction and atherosclerosis. Natural compounds have recently received special attention in relation to the treatment of disease due to their low cost and wide margin of safety. Thus, the aim of this study was to determine the possible preventive effect of guarana powder (Paullinia cupana) on memory impairment and acetylcholinesterase (AChE) activity in the brain structures of rats with Poloxamer-407-induced hyperlipidemia. Adult male Wistar rats were pretreated with guarana (12.5, 25 and 50mg/kg/day) and caffeine (0.2mg/kg/day) by gavage for a period of 30days. Simvastatin (0.04mg/kg) was administered as a comparative standard. Acute hyperlipidemia was induced with intraperitoneal injections of 500mg/kg of Poloxamer-407. Memory tests and evaluations of anxiety were performed. The cortex, cerebellum, hippocampus, hypothalamus and striatum were separated to assess acetylcholinesterase activity. Our results revealed that guarana powder was able to reduce the levels of TC and LDL-C in a manner similar to simvastatin. Guarana powder also partially reduced the liver damage caused by hyperlipidemia. Guarana was able to prevent changes in the activity of AChE and improve memory impairment due to hyperlipidemia. Guarana powder may therefore be a source of promising phytochemicals that can be used as adjuvant therapy in the management of hyperlipidemia and cognitive disorders. PMID- 27720902 TI - Targeted Differentiation of Regional Ventral Neuroprogenitors and Related Neuronal Subtypes from Human Pluripotent Stem Cells. AB - Embryoid body (EB) formation and adherent culture (AD) paradigms are equivalently thought to be applicable for neural specification of human pluripotent stem cells. Here, we report that sonic hedgehog-induced ventral neuroprogenitors under EB conditions are fated to medial ganglionic eminence (MGE), while the AD cells mostly adopt a floor-plate (FP) fate. The EB-MGE later on differentiates into GABA and cholinergic neurons, while the AD-FP favors dopaminergic neuron specification. Distinct developmental, metabolic, and adhesion traits in AD and EB cells may potentially account for their differential patterning potency. Gene targeting combined with small-molecule screening experiments identified that concomitant inhibition of Wnts, STAT3, and p38 pathways (3i) could largely convert FP to MGE under AD conditions. Thus, differentiation paradigms and signaling regulators can be integrated together to specify distinct neuronal subtypes for studying and treating related neurological diseases, such as epilepsy, Alzheimer's disease, and Parkinson's disease. PMID- 27720903 TI - Early Development of Definitive Erythroblasts from Human Pluripotent Stem Cells Defined by Expression of Glycophorin A/CD235a, CD34, and CD36. AB - The development of human erythroid cells has been mostly examined in models of adult hematopoiesis, while their early derivation during embryonic and fetal stages is largely unknown. We observed the development and maturation of erythroblasts derived from human pluripotent stem cells (hPSCs) by an efficient co-culture system. These hPSC-derived early erythroblasts initially showed definitive characteristics with a glycophorin A+ (GPA+) CD34lowCD36- phenotype and were distinct from adult CD34+ cell-derived ones. After losing CD34 expression, early GPA+CD36- erythroblasts matured into GPA+CD36low/+ stage as the latter expressed higher levels of beta-globin along with a gradual loss of mesodermal and endothelial properties, and terminally suppressed CD36. We establish a unique in vitro model to trace the early development of hPSC-derived erythroblasts by serial expression of CD34, GPA, and CD36. Our findings may provide insight into the understanding of human early erythropoiesis and, ultimately, therapeutic potential. PMID- 27720904 TI - Endogenous DNA Damage Leads to p53-Independent Deficits in Replicative Fitness in Fetal Murine Fancd2-/- Hematopoietic Stem and Progenitor Cells. AB - Our mechanistic understanding of Fanconi anemia (FA) pathway function in hematopoietic stem and progenitor cells (HSPCs) owes much to their role in experimentally induced DNA crosslink lesion repair. In bone marrow HSPCs, unresolved stress confers p53-dependent apoptosis and progressive cell attrition. The role of FA proteins during hematopoietic development, in the face of physiological replicative demand, remains elusive. Here, we reveal a fetal HSPC pool in Fancd2-/- mice with compromised clonogenicity and repopulation. Without experimental manipulation, fetal Fancd2-/- HSPCs spontaneously accumulate DNA strand breaks and RAD51 foci, associated with a broad transcriptional DNA-damage response, and constitutive activation of ATM as well as p38 stress kinase. Remarkably, the unresolved stress during rapid HSPC pool expansion does not trigger p53 activation and apoptosis; rather, it constrains proliferation. Collectively our studies point to a role for the FA pathway during hematopoietic development and provide a new model for studying the physiological function of FA proteins. PMID- 27720907 TI - Molecular beacons with JOE dye: Influence of linker and 3' couple quencher. AB - Molecular beacons carrying JOE dye (4',5'-dichloro-2',7'-dimethoxy-6 carboxyfluorescein) on a rigid or flexible linker and one or two BHQ1 quenchers have been prepared and tested in real-time PCR using Fusarium avenaceum elongation factor 1alpha DNA template. The probes were different in their structures (loop size and stem length), linkers for dye attachment (6 aminohexanol or trans-4-aminocyclohexanol), quencher composition (single and double BHQ1) to elucidate the influence of all these features. Fluorogenic properties of the probes were studied and compared to those of FAM (fluorescein) based probes. All the factors - stem length, JOE vs FAM, rigid vs flexible linker, single vs double quencher - appeared to play a considerable role in the probe's fluorescent properties and determine the usability of the probe at two different temperatures of fluorescence detection (55 degrees S and 64 degrees S). PMID- 27720906 TI - Transient RUNX1 Expression during Early Mesendodermal Differentiation of hESCs Promotes Epithelial to Mesenchymal Transition through TGFB2 Signaling. AB - The transition of human embryonic stem cells (hESCs) from pluripotency to lineage commitment is not fully understood, and a role for phenotypic transcription factors in the initial stages of hESC differentiation remains to be explored. From a screen of candidate factors, we found that RUNX1 is selectively and transiently upregulated early in hESC differentiation to mesendodermal lineages. Transcriptome profiling and functional analyses upon RUNX1 depletion established a role for RUNX1 in promoting cell motility. In parallel, we discovered a loss of repression for several epithelial genes, indicating that loss of RUNX1 impaired an epithelial to mesenchymal transition during differentiation. Cell biological and biochemical approaches revealed that RUNX1 depletion specifically compromised TGFB2 signaling. Both the decrease in motility and deregulated epithelial marker expression upon RUNX1 depletion were rescued by reintroduction of TGFB2, but not TGFB1. These findings identify roles for RUNX1-TGFB2 signaling in early events of mesendodermal lineage commitment. PMID- 27720908 TI - Molecular detection of Mycoplasma haemomuris subspecies using dnaK-targeted real time PCR with SYBR Green I and melting curve analysis. AB - Hemoplasmas cause severe infections in mammals, but these pathogens are difficult to detect and identify at the species and subspecies level because of the need for time-consuming sequence based methods. Here, we used real-time PCR with SYBR Green I targeting of the dnaK gene followed by standard melting curve analysis to achieve rapid detection and differentiation of the Mycoplasma haemomuris subspecies 'Candidatus Mycoplasma haemomuris subsp. musculi' and 'Candidatus M. haemomuris subsp. ratti'. The melting temperatures of the PCR products, 84.63 +/- 0.14 degrees C for 'Candidatus M. haemomuris subsp. musculi', and 80.72 +/- 0.16 degrees C for 'Candidatus M. haemomuris subsp. ratti', provided clear differentiation between them. Murine hemoplasma DNA samples, which were used as references, were confirmed for species by an analysis of 16S rRNA sequences. The protocol described herein provides a new rapid detection and identification method suitable for use with two recognized subspecies of M. haemomuris. PMID- 27720905 TI - A Dynamic WNT/beta-CATENIN Signaling Environment Leads to WNT-Independent and WNT Dependent Proliferation of Embryonic Intestinal Progenitor Cells. AB - Much of our understanding about how intestinal stem and progenitor cells are regulated comes from studying the late fetal stages of development and the adult intestine. In this light, little is known about intestine development prior to the formation of stereotypical villus structures with columnar epithelium, a stage when the epithelium is pseudostratified and appears to be a relatively uniform population of progenitor cells with high proliferative capacity. Here, we investigated a role for WNT/beta-CATENIN signaling during the pseudostratified stages of development (E13.5, E14.5) and following villus formation (E15.5) in mice. In contrast to the well-described role for WNT/beta-CATENIN signaling as a regulator of stem/progenitor cells in the late fetal and adult gut, conditional epithelial deletion of beta-catenin or the Frizzled co-receptors Lrp5 and Lrp6 had no effect on epithelial progenitor cell proliferation in the pseudostratified epithelium. Mutant embryos displayed obvious developmental defects, including loss of proliferation and disruptions in villus formation starting only at E15.5. Mechanistically, our data suggest that WNT signaling-mediated proliferation at the time of villus formation is driven by mesenchymal, but not epithelial, WNT ligand secretion. PMID- 27720909 TI - Mercury sulfides are much less nephrotoxic than mercury chloride and methylmercury in mice. AB - Mercury sulfides (alpha-HgS, beta-HgS) are frequently included in traditional medicines. Mercury is known for nephrotoxicity, their safety is of concern. To address this question, mice were orally administrated with Zuotai (54% beta-HgS, 30mg/kg), alpha-HgS (HgS, 30mg/kg), HgCl2 (33.6mg/kg), or MeHgCl (3.1mg/kg) for 7days, and nephrotoxicity was examined. Animal body weights were decreased by HgCl2 and to a lesser extent by MeHg, but unaltered after Zuotai and HgS. HgCl2 and MeHg produced renal tubular vacuolation, interstitial inflammation and cell degeneration with protein cysts in the tubular lumen, while these pathological lesions were mild in Zuotai and HgS-treated mice. Electron microscopy showed that HgCl2 and MeHg produced spotted swelling endothelium reticulum, while these lesions were mild or absent in Zuotai and HgS-treated mice. Renal Hg contents reached 250-300ng/mg kidney in HgCl2 and MeHg groups as compared to 2-3ng/mg in Zuotai and HgS groups. The expression of kidney injury biomarkers, kidney injury molecule-1 (Kim-1) and neutrophil gelatinase-associated lipocalin (Ngal), were increased after HgCl2 and MeHg, but unaltered after Zuotai and HgS. The expression of renal influx transporters Oat3 and Oatp4c1 was decreased, while the expression of renal efflux transporter such as Mrp2, Mrp4, and Mate2 was increased following HgCl2 and MeHg. These gene expressions were unchanged after Zuotai and HgS. In summary, both alpha-HgS and beta-HgS are less nephrotoxic than HgCl2 and MeHg, indicating that chemical forms of mercury are a major determinant of mercury disposition and toxicity. PMID- 27720911 TI - Predicted Increases in Incidence of Colorectal Cancer in Developed and Developing Regions, in Association With Ageing Populations. AB - BACKGROUND & AIMS: Population growth and changes in demographic structure are linked to trends in colorectal cancer (CRC) incidence. The aim of this study is to estimate future CRC incidence in the ageing population, and compare trends across developing and developed regions. METHODS: Cancer and population data were extracted from the International Agency for Research on Cancer. Annual incidence rates for the major types of cancer in 118 selected populations were extracted from 102 cancer registries in 39 countries worldwide. We selected 8 jurisdictions (from the United States, Europe, and Asia) that reported 20-year cancer incidence rates since 1988. Time series models were constructed to project cancer incidence, by sex and age, to 2030. Incidence rates for persons older than 65 years were combined and further adjusted for change of ageing population. We compared age-adjusted incidence rates among the jurisdictions. RESULTS: The total population older than 65 years old was 12,917,794 in 1988, and the number increased by almost 40% to 17,950,115 in 2007. In developed countries in the West CRC incidence is predicted to decrease by 16.3% in the United States, increase by 4.8% in the United Kingdom, and increase by 4.7% in Sweden by 2030. In developing countries, such as China (Shanghai), Croatia, and Costa Rica, CRC incidence is predicted to increase in a steep curve by 2030 because of the growing population and ageing effect; in 2030, the incidence increases were 60.5% for China, 47.0% for Croatia, and 18.5% for Costa Rica. We also predict CRC incidence will increase greatly by 2030 in Japan and Hong Kong, which are developed regions. CONCLUSIONS: With the exception of the United States, the incidence of CRC is expected to continue to rise in most regions in the coming decades, due to population growth and changes in demographic structure. The predicted increases are more marked in developing regions with limited health care resources. PMID- 27720910 TI - Implementing the Concept of Continuous Clinical Response Into Clinical Practice for Ulcerative Colitis. AB - BACKGROUND & AIMS: Ulcerative colitis (UC) is a complex and progressive disease that has a significant humanistic and economic impact in patients and the wider society. Disease control is still an unmet need for a large proportion of patients. The aim of this article was to review the current evidence to assess the feasibility, value, and impact of integrating continuous clinical response (CCR) as a patient-reported outcome into routine management of UC. METHODS: Literature searches in PubMed, Google Scholar, and conference proceedings were undertaken to retrieve the relevant articles regarding burden and course of disease, outcome measures in UC, tools for measuring disease activity, and models for patient's self-monitoring. RESULTS: The concept of CCR was first introduced during the PURSUIT-M trial, where evidence was provided to support the clinical and quality of life benefits of achieving CCR. However, patient monitoring as implemented during the trial was not feasible for its use in the real world. Thus, a simple self-reported score (eg, PRO2) to monitor CCR, with good correlation with more complex procedure-driven indices, was identified for its use in routine patient care. Feasibility of introducing this easy-to-use tool over time as an integral part of patient management was also explored. CONCLUSIONS: The introduction of CCR as a management goal for UC patients may pose the step change needed to improve disease course and patient's life. Providing patients with simple tools to continuously monitor their disease activity is the first step for an integrated self-monitoring model of care in UC.

AB - BACKGROUND & AIMS: Contrary to conventional wisdom, the rectoanal gradient during evacuation is negative in many healthy people, undermining the utility of anorectal high-resolution manometry (HRM) for diagnosing defecatory disorders. We aimed to compare HRM and magnetic resonance imaging (MRI) for assessing rectal evacuation and structural abnormalities. METHODS: We performed a retrospective analysis of 118 patients (all female; 51 with constipation, 48 with fecal incontinence, and 19 with rectal prolapse; age, 53 +/- 1 years) assessed by HRM, the rectal balloon expulsion test (BET), and MRI at Mayo Clinic, Rochester, Minnesota, from February 2011 through March 2013. Thirty healthy asymptomatic women (age, 37 +/- 2 years) served as controls. We used principal components analysis of HRM variables to identify rectoanal pressure patterns associated with rectal prolapse and phenotypes of patients with prolapse. RESULTS: Compared with patients with normal findings from the rectal BET, patients with an abnormal BET had lower median rectal pressure (36 vs 22 mm Hg, P = .002), a more negative median rectoanal gradient (-6 vs -29 mm Hg, P = .006) during evacuation, and a lower proportion of evacuation on the basis of MRI analysis (median of 40% vs 80%, P < .0001). A score derived from rectal pressure and anorectal descent during evacuation and a patulous anal canal was associated (P = .005) with large rectoceles (3 cm or larger). A principal component (PC) logistic model discriminated between patients with and without prolapse with 96% accuracy. Among patients with prolapse, there were 2 phenotypes, which were characterized by high (PC1) or low (PC2) anal pressures at rest and squeeze along with higher rectal and anal pressures (PC1) or a higher rectoanal gradient during evacuation (PC2). CONCLUSIONS: In a retrospective analysis of patients assessed by HRM, measurements of rectal evacuation by anorectal HRM, BET, and MRI were correlated. HRM alone and together with anorectal descent during evacuation may identify rectal prolapse and large rectoceles, respectively, and also identify unique phenotypes of rectal prolapse. PMID- 27720915 TI - Validation of a Staging System for Acute Kidney Injury in Patients With Cirrhosis and Association With Acute-on-Chronic Liver Failure. AB - BACKGROUND & AIMS: In patients with cirrhosis of the liver, acute kidney injury (AKI) is classified into 3 stages. Recent studies indicate that there are 2 subgroups of stage 1 disease, associated with different outcomes and serum levels of creatinine (SCr): stage 1A (SCr <1.5 mg/dL) and stage 1B (SCr >=1.5 mg/dL). We performed a prospective study to validate, in a large series of patients with cirrhosis, the association between this new description and patient outcomes, and assess the relationship between AKI stage and the presence of acute-on-chronic liver failure. METHODS: We collected data from 547 consecutive patients admitted for cirrhosis with acute decompensation to 2 tertiary hospitals (Italy and Spain), from February 2011 through June 2015. A total of 290 patients had AKI (53%; 197 had stage 1 disease); AKI stages were determined based on levels of SCr at diagnosis. Patients were followed up until death, liver transplantation, or for 90 days. The primary outcome was 90-day survival; secondary outcomes were progression and resolution of AKI and association with acute-on-chronic liver failure. RESULTS: Based on level of sCr at diagnosis, 58 patients had stage 1A disease and 139 had stage 1B disease. Of patients with stage 1A disease, 82% survived for 90 days; of patients with stage 1B disease, 55% survived for 90 days (P = .001). Hepatorenal syndrome and acute tubular necrosis were the most common causes of stage 1B AKI, and hypovolemia was the most common cause of stage 1A AKI. AKI progressed in a higher proportion of patients with 1B than 1A AKI (31% vs 15%; P = .017) and resolved in a higher proportion of patients with 1A disease (90% vs 52% of patients with stage 1B; P < .001). Stage 1B disease, but not 1A, was an independent predictor of AKI progression and mortality. ACLF developed in a significantly greater proportion of patients with stage 1B disease (76%) than stage 1A disease (22%; P < .001), which could account for the poor outcomes of patients with stage 1B disease. CONCLUSIONS: In a large group of patients with decompensated cirrhosis, we validated the association between AKI stages IA and IB (based on level of sCR) with survival times and AKI progression. We also associated these subgroups of AKI with development of acute-on-chronic liver failure. These findings are important for management of patients with decompensated cirrhosis. PMID- 27720917 TI - Tetrahydrocannabinol Does Not Reduce Pain in Patients With Chronic Abdominal Pain in a Phase 2 Placebo-controlled Study. AB - BACKGROUND & AIMS: Delta-9-tetrahydrocannabinol (THC) is the most abundant cannabinoid from the plant Cannabis sativa. There is only equivocal evidence that THC has analgesic effects. We performed a phase 2 controlled trial to evaluate the analgesic efficacy, pharmacokinetics, safety, and tolerability of an oral tablet containing purified THC in patients with chronic abdominal pain. METHODS: Sixty-five patients with chronic abdominal pain for 3 months or more (numeric rating scale scores of 3 or more) after surgery or because of chronic pancreatitis were randomly assigned to groups given the THC tablet or identical matching placebos for 50-52 days. Subjects in the THC group were given the tablet first in a step-up phase (3 mg 3 times daily for 5 days and then 5 mg 3 times daily for 5 days), followed by a stable dose phase (8 mg 3 times daily until days 50-52). Preceding and during the entire study period, patients were asked to continue taking their medications (including analgesics) according to prescription. Patients reported any additional pain medications in a diary. Efficacy and safety assessments were conducted preceding medication intake (day 1), after 15 days, and at 50-52 days. Plasma samples were collected on study days 1, 15, and 50-52; mean plasma concentration curves of THC and 11-OH-THC were plotted. The primary end point was pain relief, which was measured by a visual analogue scale (VAS) of the mean pain (VAS mean scores) on the basis of information from patient diaries. Secondary end points included pain and quality of life (determined from patient questionnaires), pharmacokinetics, and safety. RESULTS: At days 50-52, VAS mean scores did not differ significantly between the THC and placebo groups (F1,46 = 0.016; P = .901). Between the start and end of the study, VAS mean scores decreased by 1.6 points (40%) in the THC group compared with 1.9 points (37%) in the placebo group. No differences were observed in secondary outcomes. Oral THC was generally well-absorbed. Seven patients in the THC group stopped taking the tablets because of adverse events, compared with 2 patients in the placebo group. All (possibly) related adverse events were mild or moderate. CONCLUSIONS: In a phase 2 study, we found no difference between a THC tablet and a placebo tablet in reducing pain measures in patients with chronic abdominal pain. THC, administered 3 times daily, was safe and well tolerated during a 50-day to 52-day treatment period. ClinicalTrials.gov number: NCT01562483 and NCT01551511. PMID- 27720916 TI - Hepatic Encephalopathy Is Associated With Mortality in Patients With Cirrhosis Independent of Other Extrahepatic Organ Failures. AB - BACKGROUND & AIMS: Although survival times have increased for patients with cirrhosis, hepatic encephalopathy (HE) remains a major complication and its relative contribution toward mortality in North America is unclear. We investigated whether HE is associated with mortality independent of extrahepatic organ failures (EHOFs). METHODS: We collected data from the North American Consortium for Study of End-stage Liver Disease database of hospitalized patients with cirrhosis at tertiary-care centers. EHOFs were defined as need for ventilation (respiratory failure), dialysis (renal failure), or shock (circulatory failure). We analyzed in-hospital and 30-day mortality for patients with varying HE grades and EHOF using adjusted models. RESULTS: We analyzed data from 1560 patients, 516 with HE (371 grade 1-2 and 145 grade 3-4). Patients with maximum HE grade 3-4 HE during hospitalization had a higher median model for end stage liver disease (MELD) score (22) than patients with HE grade 1-2 (MELD score, 19) or no HE (MELD score, 18) (P < .0001). Thirty-day mortality for patients with HE grade 3-4 was significantly higher (38%) than for patients with HE grade 1-2 (8%) or no HE (7%). A total of 107 patients had 2 or more EHOFs, with or without HE; 151 had 1 EHOF and 1302 had no organ failure. Unadjusted mortality was highest for patients with HE of grade 3-4 with 2 EHOFs (n = 44). On regression analysis, HE severity was significantly associated with in-hospital and 30-day mortality, independent of any EHOF, white blood cell count, systemic inflammatory response syndrome, or MELD score (odds ratio, 3.3; P < .0001). CONCLUSIONS: In an analysis of more than 1500 patients hospitalized for cirrhosis, HE of grade 3 or 4 was associated with higher in-hospital and 30-day mortality, independently of failure of other organs. PMID- 27720919 TI - Evaluation of the Tobacco Heating System 2.2. Part 2: Chemical composition, genotoxicity, cytotoxicity, and physical properties of the aerosol. AB - The chemical composition, in vitro genotoxicity, and cytotoxicity of the mainstream aerosol from the Tobacco Heating System 2.2 (THS2.2) were compared with those of the mainstream smoke from the 3R4F reference cigarette. In contrast to the 3R4F, the tobacco plug in the THS2.2 is not burnt. The low operating temperature of THS2.2 caused distinct shifts in the aerosol composition compared with 3R4F. This resulted in a reduction of more than 90% for the majority of the analyzed harmful and potentially harmful constituents (HPHCs), while the mass median aerodynamic diameter of the aerosol remained similar. A reduction of about 90% was also observed when comparing the cytotoxicity determined by the neutral red uptake assay and the mutagenic potency in the mouse lymphoma assay. The THS2.2 aerosol was not mutagenic in the Ames assay. The chemical composition of the THS2.2 aerosol was also evaluated under extreme climatic and puffing conditions. When generating the THS2.2 aerosol under "desert" or "tropical" conditions, the generation of HPHCs was not significantly modified. When using puffing regimens that were more intense than the standard Health Canada Intense (HCI) machine-smoking conditions, the HPHC yields remained lower than when smoking the 3R4F reference cigarette with the HCI regimen. PMID- 27720920 TI - Antispasmodic effect of selected Citrus flavonoids on rat isolated jejunum specimens. AB - Citrus flavonoids are acknowledged for numerous pharmacological activities, including the myorelaxant effect on various smooth muscles. However, there is no data on their effect on jejunum contractility. Therefore, the aim of the study at hand was to evaluate the impact of hesperetin and diosmetin along with their glycosides on the motoric activity of intestine and to verify the possible mechanism of hesperetin-induced effect. The experiments were performed on rat isolated jejunum strips and were conducted under isometric conditions. Hesperetin and diosmetin, but not hesperidin and diosmin, dose-dependently (10-100uM) and reversibly inhibited acetylcholine (1uM) and KCl (80mM) induced contractile activity. The antispasmodic effect of hesperetin was partially blocked by 4 aminopyridine (100uM), glibenclamide (100uM) and NG-nitro-L-arginine methyl ester (L-NAME, 100uM). By contrast, apamin (0.1uM), tetraethylammonium (500uM) and methylene blue (10uM) did not affect the magnitude of hesperetin-induced myorelaxant effect. Indomethacin (10uM) increased the force of hesperetin-evoked reaction. In conclusion, hesperetin and diosmetin are potent myorelaxant agents. The antispasmodic effect of hesperetin is partially mediated by fast current low voltage activated K+ channels, voltage-independent K+ channels and involves the nitric oxide pathway. Finally, hesperetin shows a synergistic effect with indomethacin towards jejunal KCl-precontracted smooth muscle. PMID- 27720918 TI - Methylmercury induces an initial increase in GABA-evoked currents in Xenopus oocytes expressing alpha1 and alpha6 subunit-containing GABAA receptors. AB - Early onset effects of methylmercury (MeHg) on recombinant alpha1beta2gamma2S or alpha6beta2gamma2S subunit-containing GABAA receptors were examined. These are two of the most prevalent receptor types found in cerebellum-a consistent target of MeHg-induced neurotoxicity. Heterologously expressed receptors were used in order to: (1) isolate receptor-mediated events from extraneous effects of MeHg due to stimulation of the receptor secondary to increased release of GABA seen with MeHg in neurons in situ and (2) limit the phenotypes of GABAA receptors present at one time. Initial changes in IGABA in Xenopus laevis oocytes expressing either alpha1beta2gamma2S or alpha6beta2gamma2S receptors were compared during continuous bath application of MeHg. A time-dependent increase in IGABA mediated by both receptor subtypes occurred following the first 25-30min of MeHg (5MUM) exposure. In alpha6beta2gamma2S containing receptors, the MeHg induced increase in IGABA was less pronounced compared to that mediated by alpha1beta2gamma2S containing receptors, although the pattern of effects was generally similar. Washing with MeHg-free solution reversed the increase in current amplitude. Application of bicuculline at the time of peak potentiation of IGABA rapidly and completely reversed the MeHg-induced currents. Therefore these MeHg-increased inward currents are mediated specifically by the two subtypes of GABAA receptors and appear to entail direct actions of MeHg on the receptor. However bicuculline did not affect stimulation by MeHg of oocyte endogenous Cl- mediated current, which presumably results from increased [Ca2+]i. Thus, MeHg initially potentiates IGABA in oocytes expressing either alpha1beta2gamma2S or alpha6beta2gamma2S receptors prior to its more defined later effects, suggesting that MeHg may initially interact directly with GABAA receptors in a reversible manner to cause this potentiation. PMID- 27720921 TI - Hesperidin derivative-11 inhibits fibroblast-like synoviocytes proliferation by activating Secreted frizzled-related protein 2 in adjuvant arthritis rats. AB - Hesperidin (HDN), a flavanone glycoside derived from the citrus cultivation, has a multitude of pharmacological properties, which include antioxidant, anti inflammatory, hypolipidaemic and anti-carcinogenic actions, but the underlying mechanisms by which treatment of HDN attenuates Rheumatoid Arthritis (RA) remain elusive. Here we engaged to determine whether Hesperidin derivative-11(HDND-11), a HDN derivative with enhanced water-solubility and bioavailability, is effective on treating arthritis in rats. In this study, results of 3-(4, 5-dimethylthiazol 2-yl)-2, 5-diphenyltetra-zolium bromide (MTT) assay and Flow cytometry indicated that administration of HDND-11 inhibited proliferation of fibroblast-like synoviocytes (FLS). Results of Western blot, Real-time quantitative PCR (RT-qPCR) analysis and Immunofluorescence staining demonstrated that HDND-11 was able to up regulate the expression of Secreted frizzled-related proteins 2 (SFRP2) and diminish DNA methyltransferase 1(DNMT1) expression. We also identified that the effect of DNMT1 inhibition was completely similar to the effects of HDND-11 on SFRP2 gene expression. Furthermore, our results indicated that treatment with HDND-11 could suppress activation of Wnt pathway. Taken together, we found that the HDND-11diminished inhibitory effect of DNMT1 on SFRP2, thereby down-regulated beta-catenin expression and inhibited the activation of Wnt signaling pathways to inhibit FLS growth. PMID- 27720922 TI - Interaction between G Protein-Coupled Receptor 143 and Tyrosinase: Implications for Understanding Ocular Albinism Type 1. AB - Developmental eye defects in X-linked ocular albinism type 1 are caused by G protein coupled receptor 143 (GPR143) mutations. Mutations result in dysfunctional melanosome biogenesis and macromelanosome formation in pigment cells, including melanocytes and retinal pigment epithelium. GPR143, primarily expressed in pigment cells, localizes exclusively to endolysosomal and melanosomal membranes unlike most G protein-coupled receptors, which localize to the plasma membrane. There is some debate regarding GPR143 function and elucidating the role of this receptor may be instrumental for understanding neurogenesis during eye development and for devising therapies for ocular albinism type I. Many G protein-coupled receptors require association with other proteins to function. These G protein-coupled receptor-interacting proteins also facilitate fine-tuning of receptor activity and tissue specificity. We therefore investigated potential GPR143 interaction partners, with a focus on the melanogenic enzyme tyrosinase. GPR143 coimmunoprecipitated with tyrosinase, while confocal microscopy demonstrated colocalization of the proteins. Furthermore, tyrosinase localized to the plasma membrane when coexpressed with a GPR143 trafficking mutant. The physical interaction between the proteins was confirmed using fluorescence resonance energy transfer. This interaction may be required in order for GPR143 to function as a monitor of melanosome maturation. Identifying tyrosinase as a potential GPR143 binding protein opens new avenues for investigating the mechanisms that regulate pigmentation and neurogenesis. PMID- 27720923 TI - Sperm-less males modulate female behaviour in Ceratitis capitata (Diptera: Tephritidae). AB - In the Mediterranean fruit fly, Ceratitis capitata (Wiedemann)(Diptera: Tephritidae), mating has a strong impact on female biology, leading to a decrease in sexual receptivity and increased oviposition and fecundity. Previous studies suggest that sperm transfer may play a role in inducing these behavioural changes. Here we report the identification of a medfly innexin gene, Cc-inx5, whose expression is limited to the germ-line of both sexes. Through RNA interference of this gene, we generated males without testes and, consequently, sperm, but apparently retaining all the other reproductive organs intact. These sperm-less males were able to mate and, like their wild-type counterparts, to induce in their partners increased oviposition rates and refractoriness to remating. Interestingly, matings to sperm-less males results in oviposition rates higher than those induced by copulation with control males. In addition, the observed female post-mating behavioural changes were congruent with changes in transcript abundance of genes known to be regulated by mating in this species. Our results suggest that sperm transfer is not necessary to reduce female sexual receptivity and to increase oviposition and fecundity. These data pave the way to a better understanding of the role/s of seminal components in modulating female post-mating responses. In the long term, this knowledge will be the basis for the development of novel approaches for the manipulation of female fertility, and, consequently, innovative tools to be applied to medfly control strategies in the field. PMID- 27720924 TI - Five new lactone derivatives from the stems of Dendrobium nobile. AB - Five new lactone derivatives decumbic acids A and B (1 and 2), (-)-decumbic acid (3a), (-)- and (+)-dendrolactone (4a and 4b) together with four known compounds (3b and 5-7) were isolated from the stems of Dendrobium nobile. Their structures were elucidated using comprehensive spectroscopic methods. Compounds 3a and 3b, 4a and 4b were isolated as two pair of enantiomers by chiral HPLC. The absolute configurations of 1, 2, 3a, 4a and 4b were determined by optical rotation and X ray crystallographic analysis. The inhibitory activities of all compounds against nine phytopathogenic fungi and three cancer cell lines were evaluated. PMID- 27720925 TI - Broadening the antibacterial spectrum of histidine kinase autophosphorylation inhibitors via the use of epsilon-poly-L-lysine capped mesoporous silica-based nanoparticles. AB - Two-component systems (TCS) regulate diverse processes such as virulence, stress responses, metabolism and antibiotic resistance in bacteria but are absent in humans, making them promising targets for novel antibacterials. By incorporating recently described TCS histidine kinase autophosphorylation inhibitors (HKAIs) into epsilon-poly-L-lysine capped nanoparticles (NPs) we could overcome the Gram negative (Gr-) permeability barrier for the HKAIs. The observed bactericidal activity against Gr- bacteria was shown to be due to the enhanced delivery and internalization of the HKAIs and not an inhibitory or synergistic effect of the NPs. The NPs had no adverse effects on mammalian cell viability or the immune function of macrophages in vitro and showed no signs of toxicity to zebrafish larvae in vivo. These results show that HKAIs are promising antibacterials for both Gr- and Gr+pathogens and that NPs are a safe drug delivery technology that can enhance the selectivity and efficacy of HKAIs against bacteria. PMID- 27720926 TI - Profiling the relationship between tumor-associated macrophages and pharmacokinetics of liposomal agents in preclinical murine models. AB - The mononuclear phagocyte system (MPS) has previously been shown to significantly affect the clearance, tumor delivery, and efficacy of nanoparticles (NPs). This study profiled MPS cell infiltration in murine preclinical tumor models and evaluated how these differences may affect tumor disposition of PEGylated liposomal doxorubicin (PLD) in models sensitive and resistant to PLD. Significant differences in MPS presence existed between tumor types (e.g. ovarian versus endometrial), cell lines within the same tumor type, and location of tumor implantation (i.e. flank versus orthotopic xenografts). Further, the differences in MPS presence of SKOV-3 ovarian and HEC1A endometrial orthotopic cancer models may account for the 2.6-fold greater PLD tumor exposure in SKOV-3, despite similar plasma, liver and spleen exposures. These findings suggest that profiling the presence of MPS cells within and between tumor types is important in tumor model selection and in tumor types and patients likely to respond to NP treatment. PMID- 27720927 TI - Facile and phase-defined determination of HLA alleles with morpholino functionalized nanoparticle probes. AB - A number of human leukocyte antigen (HLA) gene alleles have been found to be genetic risk markers for immunologically mediated drug hypersensitivity. Clinical adoption of HLA pharmacogenomics requires facile and accurate allele screening assays. As HLA genes are highly polymorphic, currently available methods are usually labor-intensive and liable to generate false positives. Herein we report a general strategy for screening HLA alleles with nanoparticle probes. Specific HLA alleles can be identified by gauging three to five sequence variants. Single polymerase chain reaction (PCR) and dual-PCR methods have been proposed to achieve phase-defined determination of the sequence variants. Morpholino functionalized gold nanoparticle probes allow for colorimetric and highly specific detection. Assays for HLA-B*58:01 and HLA-B*15:02 have been developed and validated with 49 selected human genomic DNA samples. The facile nanoparticle probe-based assays can be implemented easily in molecular diagnostic laboratories for accurate and cost-effective screening of HLA alleles. PMID- 27720928 TI - In vivo tumor targeting and biodistribution evaluation of paramagnetic solid lipid nanoparticles for magnetic resonance imaging. AB - The current study was performed to evaluate the in vivo efficiency of a new nano sized contrast agent called paramagnetic Solid Lipid Nanoparticles, pSLNs, having promising relaxivity properties for Magnetic Resonance Imaging application. Good stability and stealth properties toward macrophage uptake have been demonstrated. An in vivo MRI study resulted in an improved signal enhancement in the tumor tissue particularly when folate as targeting ligand was used to decorate the nanoparticles surface. Afterward, the biodistribution of pSLNs in several organs was investigated. The accumulation of pSLNs in kidneys, femoral bones, spleen and brain was quite low while high tropism of pSLNs was found for the liver. In this regard, approaches to improve the rate of the hepatic clearance have been proposed. PMID- 27720929 TI - Bio-based polyurethane for tissue engineering applications: How hydroxyapatite nanoparticles influence the structure, thermal and biological behavior of polyurethane composites. AB - In this work, thermoset polyurethane composites were prepared by the addition of hydroxyapatite nanoparticles using the reactants polyol polyether and an aliphatic diisocyanate. The polyol employed in this study was extracted from the Euterpe oleracea Mart. seeds from the Amazon Region of Brazil. The influence of hydroxyapatite nanoparticles on the structure and morphology of the composites was studied using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS), the structure was evaluated by Fourier transform infrared spectroscopy (FT-IR), thermal properties were analyzed by thermogravimetry analysis (TGA), and biological properties were studied by in vitro and in vivo studies. It was found that the addition of HA nanoparticles promoted fibroblast adhesion while in vivo investigations with histology confirmed that the composites promoted connective tissue adherence and did not induce inflammation. In this manner, this study supports the further investigation of bio-based, polyurethane/hydroxyapatite composites as biocompatible scaffolds for numerous tissue engineering applications. PMID- 27720930 TI - Adaptation of targeted nanocarriers to changing requirements in antimalarial drug delivery. AB - The adaptation of existing antimalarial nanocarriers to new Plasmodium stages, drugs, targeting molecules, or encapsulating structures is a strategy that can provide new nanotechnology-based, cost-efficient therapies against malaria. We have explored the modification of different liposome prototypes that had been developed in our group for the targeted delivery of antimalarial drugs to Plasmodium-infected red blood cells (pRBCs). These new models include: (i) immunoliposome-mediated release of new lipid-based antimalarials; (ii) liposomes targeted to pRBCs with covalently linked heparin to reduce anticoagulation risks; (iii) adaptation of heparin to pRBC targeting of chitosan nanoparticles; (iv) use of heparin for the targeting of Plasmodium stages in the mosquito vector; and (v) use of the non-anticoagulant glycosaminoglycan chondroitin 4-sulfate as a heparin surrogate for pRBC targeting. The results presented indicate that the tuning of existing nanovessels to new malaria-related targets is a valid low-cost alternative to the de novo development of targeted nanosystems. PMID- 27720931 TI - CysLT1R downregulation reverses intracerebroventricular streptozotocin-induced memory impairment via modulation of neuroinflammation in mice. AB - Our previous studies showed that cysteinyl leukotrienes receptor 1 (CysLT1R) is upregulated in amyloid-beta (Abeta)-induced neurotoxicity and that administration of CysLT1R antagonists such as pranlukast or montelukast can ameliorate memory impairment in mice. In the current study, we sought to explore the role of CysLT1R in intracerebroventricular streptozotocin (STZ-ICV)-induced mouse model of memory impairment and neuroinflammation through shRNA-mediated knockdown of CysLT1R and also its pharmacological blockade by pranlukast. ICR mice were infused with STZ (3.0mg/kg) by a single bilateral stereotaxic ICV microinjection followed by administration of CysLT1R-shRNA (intra-hippocampal) or pranlukast (intragastric, IG). After 21days, a set of behavioral and biochemical tests were performed in order to assess the degree of memory impairment and neuroinflammation in mice. STZ-infused mice spent less time in the target quadrant of Morris water maze test and took more time to find the shock-free arm in modified Y-maze test, which were rescued in the CysLT1R-knockdowned or pranlukast-treated mice. STZ-induced memory impairment was also accompanied by an elevated level of hippocampal CysLT1R, microglial activation, increased IL-1beta, and TNF-alpha. Such elevation of these factors was found to be mediated through the classical NF-kappaB pathway and administration of CysLT1R-shRNA or pranlukast for 21days reversed all these parameters, suggesting a role of CysLT1R in STZ induced memory deficit and neuroinflammation. PMID- 27720932 TI - Hydrogen sulfide donors alleviate itch secondary to the activation of type-2 protease activated receptors (PAR-2) in mice. AB - Hydrogen sulfide (H2S) has been highlighted as an endogenous signaling molecule and we have previously found that it can inhibit histamine-mediated itching. Pruritus is the most common symptom of cutaneous diseases and anti-histamines are the usual treatment; however, anti-histamine-resistant pruritus is common in some clinical settings. In this way, the involvement of mediators other than histamine in the context of pruritus requires new therapeutic targets. Considering that the activation of proteinase-activated receptor 2 (PAR-2) is involved in pruritus both in rodents and humans, in this study we investigated the effect of H2S donors on the acute scratching behavior mediated by PAR-2 activation in mice, as well as some of the possible pharmacological mechanisms involved. The intradermal injection of the PAR-2 peptide agonist SLIGRL-NH2 (8-80nmol) caused a dose dependent scratching that was unaffected by intraperitoneal pre-treatment with the histamine H1 antagonist pyrilamine (30mg/kg). Co-injection of SLIGRL-NH2 (40nmol) with either the slow-release H2S donor GYY4137 (1 and 3nmol) or the spontaneous donor NaHS (1 and 0.3nmol) significantly reduced pruritus. Co treatment with the KATP channel blocker glibenclamide (200nmol) or the nitric oxide (NO) donor sodium nitroprusside (10nmol) abolished the antipruritic effects of NaHS; however, the specific soluble guanylyl cyclase inhibitor ODQ (30MUg) had no significant effects. The transient receptor potential ankyrin type 1 (TRPA1) antagonist HC-030031 (20MUg) significantly reduced SLIGRL-NH2-induced pruritus; however pruritus induced by the TRPA1 agonist AITC (1000nmol) was unaffected by NaHS. Based on these data, we conclude that pruritus secondary to PAR-2 activation can be reduced by H2S, which acts through KATP channel opening and involves NO in a cyclic guanosine monophosphate (cGMP)-independent manner. Furthermore, TRPA1 receptors mediate the pruritus induced by activation of PAR-2, but H2S does not interfere with this pathway. These results provide additional support for the development of new therapeutical alternatives, mainly intended for treatment of pruritus in patients unresponsive to anti-histamines. PMID- 27720933 TI - Activation of the pro-migratory bone morphogenetic protein receptor 1B gene in human MDA-MB-468 triple-negative breast cancer cells that over-express CYP2J2. AB - Secondary metastases are the leading cause of mortality in patients with breast cancer. Cytochrome P450 (CYP) 2J2 (CYP2J2) is upregulated in many human tumors and generates epoxyeicosanoids from arachidonic acid that promote tumorigenesis and metastasis, but at present there is little information on the genes that mediate these actions. In this study MDA-MB-468 breast cancer cells were stably transfected with CYP2J2 (MDA-2J2 cells) and Affymetrix microarray profiling was undertaken. We identified 182 genes that were differentially expressed in MDA-2J2 cells relative to control (MDA-CTL) cells (log[fold of control] >=2). From gene ontology pathway analysis bone morphogenetic protein (BMP) receptor 1B (BMPR1B) emerged as an important upregulated gene in MDA-2J2 cells. Addition of the BMPR1B ligand BMP2 stimulated the migration of MDA-2J2 cells, but not MDA-CTL cells, from 3D-matrigel droplets. Migration of MDA-2J2 cells was prevented by the BMPR antagonist dorsomorphin. These findings indicate that over-expression of CYP2J2 in MDA-MB-468-derived breast cancer cells activates BMPR1B expression that may contribute to increased migration. Targeting BMPR1B may be a novel approach to inhibit the metastatic activity of breast cancers that contain high levels of CYP2J2. PMID- 27720934 TI - In-vivo organ engineering: Perfusion of hepatocytes in a single liver lobe scaffold of living rats. AB - Organ decellularization is emerging as a promising regenerative medicine approach as it is able to provide an acellular, three-dimensional biological scaffold material that can be seeded with living cells for organ reengineering. However this application is currently limited to donor-derived decellularized organs for reengineering in vitro and no study has been conducted for re-engineering the decellularized organ in vivo. We developed a novel technique of a single liver lobe decellularization in vivo in live animals. Using a surgical method to generate a by-pass circulation through the portal vein and infra-hepatic vena cava with a perfusion chamber system, we decellularized the single liver lobe and recellularized it with allogenic primary hepatocytes. Our results showed that the decellularization process in vivo can preserve the vascular structural network and functional characteristics of the native liver lobe. It allows for efficient recellularization of the decellularized liver lobe matrix with allogenic primary hepatocytes. Upon the re-establishment of blood circulation, the recellularized liver lobe is able to gain the function and the allogenic hepatocytes are able to secret albumin. Our findings provide a proof of principle for the in vivo reengineering of liver. PMID- 27720935 TI - Systemic inflammatory profiles and their relationships with demographic, behavioural and clinical features in acute low back pain. AB - Systemic inflammation is linked with development and persistence of many pathological pain states. Although chronic phase inflammatory responses are well reported, the acute phase has received limited attention. Here we investigated circulating pro-inflammatory cytokines and C-reactive protein (CRP), and explored their relationships with symptom severity and other factors in acute low back pain (LBP). Ninety-nine individuals within two weeks of onset of acute LBP and 55 pain-free controls completed questionnaires related to their pain (visual analogue scale, VAS) and disability, behaviour, sleep quality and psychological status. CRP, interleukin-6 (IL-6), tumor necrosis factor (TNF) and interleukin 1beta (IL-1beta) were measured from serum samples. Biomarkers were compared between LBP and control participants, and in a separate analysis, for those with "high-pain" (VAS ?4) and "low-pain" (VAS <4). The relationships between biomarkers and all other variables, including other cytokines/CRP were assessed. CRP was higher in LBP than controls and in those with high- than low-pain (p<0.01). IL-6 was higher in those with high- than low-pain (p<0.05), but not controls. Various pain and non-pain factors were associated with each biomarker differently. These findings suggest systemic CRP and IL-6 are important contributors to inflammation in the early post-onset phase of LBP and that various factors can shape these responses.

AB - B-cell receptor (BCR) signaling plays a pivotal role in the pathogenesis of diffuse large B-cell lymphoma (DLBCL) and targeting the BCR pathway is a highly promising therapeutic strategy in this malignancy. The oncogenic microRNA miR-17 92 modulates multiple cellular processes such as survival, proliferation, apoptosis, angiogenesis, and BCR signaling. In the present study, we identified new targets of miR-17-92, PTPROt (protein phosphatase, receptor type O, truncated) and PP2A (protein phosphatase 2A) phosphatases, which regulate the activity of spleen tyrosine kinase (SYK) and AKT, critical components of BCR signal transduction in DLBCL cells. Introduction of miR-17-92 into DLBCL cells dampened the expression of the PTPROt and PP2A regulatory subunits PPP2R2A (protein phosphatase 2, regulatory subunit B, alpha) and PPP2R5E (protein phosphatase 2, regulatory subunit B, epsilon isoform) and increased the magnitude of SYK and AKT phosphorylation upon BCR ligation. Finally, we found that miR-17 92 expression modulates response to inhibitors of BCR signaling because downregulation of miR-17-92 increased SYK inhibitor-mediated toxicity in DLBCL cells. Our study reveals novel posttranscriptional regulatory pathways that contribute to the deregulation of BCR signaling and modulate SYK inhibitor activity in DLBCL.

AB - Current treatment strategies for acute leukemias largely rely on nonspecific cytotoxic drugs that result in high therapy-related morbidity and mortality. Cost effective, pertinent animal models are needed to link in vitro studies with the development of new therapeutic agents in clinical trials on a high-throughput scale. However, targeted therapies have had limited success moving from bench to clinic, often due to unexpected off-target effects. The zebrafish has emerged as a reliable in vivo tool for modeling human leukemia. Zebrafish genetic and xenograft models of acute leukemia provide an unprecedented opportunity to conduct rapid, phenotype-based screens. This allows for the identification of relevant therapies while simultaneously evaluating drug toxicity, thus circumventing the limitations of target-centric approaches. PMID- 27720938 TI - Identification of gene expression profiling associated with erlotinib-related skin toxicity in pancreatic adenocarcinoma patients. AB - Erlotinib is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor that showed activity against pancreatic ductal adenocarcinoma (PDAC). The drug's most frequently reported side effect as a result of EGFR inhibition is skin rash (SR), a symptom which has been associated with a better therapeutic response to the drug. Gene expression profiling can be used as a tool to predict which patients will develop this important cutaneous manifestation. The aim of the present study was to identify which genes may influence the appearance of SR in PDAC patients. The study included 34 PDAC patients treated with erlotinib: 21 patients developed any grade of SR, while 13 patients did not (controls). Before administering any chemotherapy regimen and the development of SR, we collected RNA from peripheral blood samples of all patients and studied the differential gene expression pattern using the Illumina microarray platform HumanHT-12 v4 Expression BeadChip. Seven genes (FAM46C, IFITM3, GMPR, DENND6B, SELENBP1, NOL10, and SIAH2), involved in different pathways including regulatory, migratory, and signalling processes, were downregulated in PDAC patients with SR. Our results suggest the existence of a gene expression profiling significantly correlated with erlotinib-induced SR in PDAC that could be used as prognostic indicator in this patients. PMID- 27720939 TI - Differential expression of microRNAs from miR-17 family in the cerebellum of mucopolysaccharidosis type I mice. AB - Mucopolysaccharidosis type I (MPS I) is caused by deficiency of alpha-l iduronidase, involved in degradation of glycosaminoglycans. Clinical manifestations are widely variable and patients with severe phenotype present developmental delay and cognitive decline, among other systemic alterations. MPS I patients present secondary accumulation of gangliosides in neuronal cells, besides accumulation of undegraded glycosaminoglycans. Reduction of Neu1 expression has been previously observed in the cerebellum of MPS I mice; to be active, neuraminidase 1 forms the lysosomal multienzyme complex (LMC) with two other proteins, beta-galactosidase and protective protein/cathepsin A, involved in stepwise degradation of gangliosides in the lysosomes. In this study, we evaluated relative expression of LMC genes and six possible regulators of their expression, microRNAs (miRNAs) from miR-17 family, which are predicted to target at least two LMC components, in the cerebellum of MPS I mice by real-time PCR. Neu1 was significantly underexpressed in MPS I mice cerebellum, whereas expression of other LMC genes was similar to controls. miR-20b and miR-106b were differentially expressed in MPS I mice, suggesting that they may be involved in the reduction of Neu1 expression; miR-20b-5p was overexpressed while miR-20b-3p and miR-106b-5p were underexpressed. The ratio between miR-20b-3p and miR-20b-5p was also altered in cerebellum of MPS I mice. Confirmation of binding predictions and analysis of the direct role of these miRNAs in the regulation of Neu1 expression could bring important information regarding LMC function. Since miRNAs from miR-17 family are involved in regulation of diverse biological processes, our results also point to new pathogenic cascades to be investigated in MPS I. PMID- 27720940 TI - Differentially expressed mitochondrial genes in breast cancer cells: Potential new targets for anti-cancer therapies. AB - It has been reported that tumor growth and proliferation correspond to mitochondrial dysfunction and that the tumor cellular microenvironment plays a key role in tumor progression, representing an area that might be manipulated to confer therapeutic anti-tumor benefits. In this article, we have identified mitochondrial genes, largely nuclear-encoded genes, which are differentially expressed in breast cancer epithelial and stromal cells compared to cells from normal breast tissues. We determined that gene expression of the mitochondrial membrane respiratory chain complex I and IV and ATP synthesis were reduced in both in epithelial and stromal cancer cells compared to normal breast cells. We also found transport-related genes were significantly more highly expressed in breast cancer epithelial cells. Our data also suggest that mitochondria are likely to proliferate in breast cancer stromal cells, which is supported by the observation that MRPL12, POLG, and RNASEH1 are all up-regulated in cancerous stromal cells. In addition, we present an improved simulated annealing algorithm, SANetWalker, which can be used to detect the functional module. At the same time, this method has a minimal effect on network topology and can be used to identify the highest confidence functional module. Using SANetWalker, we obtained the highest confidence (90%) functional module with a fumarate hydratase (FH) centered network with 40 nodes and 107 edges. Functional analysis revealed that glutamine metabolism genes were significantly up-regulated in both epithelial and stromal cells from breast cancer tissues, which implicates glutamine metabolism in breast cancer growth and metastasis. PMID- 27720941 TI - The synergistic effect of photodynamic therapy and photothermal therapy in the presence of gold-gold sulfide nanoshells conjugated Indocyanine green on HeLa cells. AB - BACKGROUND: Photodynamic therapy (PDT) and photothermal therapy (PTT) are two known optical remedies of cancer. PTT can be combined with other therapies. One of the limitations of optical therapies is the penetration of light into biological tissues, which reduces its effectiveness due to usage of photosensitizers and PTT agents, which are absorbed in the NIR region that provides the maximum penetration. For instance, Indocyanine green (ICG) serves as a photosensitizer and Gold nanostructures as agents for PTT. GGS is a gold nanoshell with two absorption peaks in the NIR and visible regions. The aim of this study is to evaluate the synergistic effect of PDT and PTT in the presence of GGS conjugated with ICG. METHODS: After synthesizing GGS, ICG was conjugated with GGS. The specifications and cytotoxicity of agents were identified. Cells were irradiated by an 808nm laser with or without the agents and three laser outputs were achieved, with each having four different exposure times. The viability of treated cells was determined via MTT assay. RESULT: The irradiation of the laser did not produce any significant effect by itself or in the presence of GGS. The maximum cell death recorded for GGS, ICG and GGS-ICG were 15+/-7%, 50+/-3% and 31+/-3% respectively. ICG and GGS-ICG differs significantly for exposures higher than 2250J/cm2. CONCLUSION: The conjugate was provided through a simple process and a greater chemical stability compared to GGS was achieved. Moreover, it induced a stronger photodynamic and photothermal effect on the cells. This is a promising result which can help enhance the effectiveness of a minimally invasive treatment. PMID- 27720942 TI - Treatment of unresectable extrahepatic cholangiocarcinoma using hematoporphyrin photodynamic therapy: A prospective study. AB - BACKGROUND: The available evidence of Photodynamic therapy (PDT) combined with stent placement treatment for unresectable extrahepatic cholangiocarcinoma (EHCC) is still insufficient. It also remains unclear whether PDT influences systemic inflammatory response. AIM: To explore the clinical efficacy and safety of the combination treatment and the systemic inflammatory response in patients with EHCC. METHODS: Patients with unresectable EHCC underwent either the combined treatment using Hematoporphyrin PDT and stent placement (PDT+stent group, n=12) or stent-only (stent group, n=27). The primary end-point was overall survival. Tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 levels were measured. Quality of life was assessed using the Karnofsky performance scale (KPS) every 3 months. RESULTS: Average survival time (13.8 vs. 9.6 months), and 6-month (91.7% vs. 74.1%), and 1-year (58.3% vs. 3.7%) survival rates of PDT+stent group were significantly increased compared with the stent group. KPS scores in the PDT+stent group were significantly improved. TNF-alpha and IL-6 levels were significantly increased in the PDT+stent group. CONCLUSION: Hematoporphyrin-PDT combined with stent placement is an effective and safe treatment for EHCC. The treatment might promote systemic inflammatory response.

CONCLUSION: This is the first report of CVA16 in Peru and provides valuable baseline data about its potential distribution in South America, as well as evidence of a potential divergent genotype that has never before been reported. PMID- 27720945 TI - Evaluation of the rapid influenza detection tests GOLD SIGN FLU and Quick Navi Flu for the detection of influenza A and B virus antigens in adults during the influenza season. AB - As the characteristics and accuracy of rapid influenza detection tests (RIDTs) vary, the development of a high-performance RIDT has been eagerly anticipated. In this study, the new RIDT GOLD SIGN FLU and the existing RIDT Quick Navi-Flu were evaluated in terms of detecting the antigens of influenza viruses A and B in Japanese adults with influenza-like symptoms. The study was performed from December 2013 to March 2014. Among the 123 patients from whom nasopharyngeal swab specimens were collected, 59 tested positive by viral isolation as the gold standard method (influenza A, n=38; influenza B, n=21). For GOLD SIGN FLU, the sensitivities were 73.7% and 81.0%, and the specificities were 97.6% and 98.0% for influenza A and B, respectively. For Quick Navi-Flu, the sensitivities were 86.8% and 85.7%, and the specificities were 98.8% and 100% for influenza A and B, respectively. The time to the appearance of the line on the test strip was less than 3min for influenza A and less than 2min for influenza B with both RIDTs in more than 90% of cases. GOLD SIGN FLU was useful for diagnosing influenza A, and the result was readily available for influenza B particularly among adult patients. Quick Navi-Flu showed better sensitivities and specificities than GOLD SIGN FLU. PMID- 27720943 TI - The V-motifs facilitate the substrate capturing step of the PTS elevator mechanism. AB - We propose that the alternative crystal forms of outward open UlaA (which are experimental, not simulated, and contain the substrate in the cavity) can be used to interpret/validate the MD results from MalT (the substrate capture step, which involves the mobile second TMSs of the V-motifs, TMSs 2 and 7). Since the crystal contacts are the same between the two alternative crystal forms of outward open UlaA, the striking biological differences noted, including rearranged hydrogen bonds and salt bridge coordination, are not attributable to crystal packing differences. Using transport assays, we identified G58 and G286 as essential for normal vitamin C transport, but the comparison of alternative crystal forms revealed that these residues to unhinge TMS movements from substrate-binding side chains, rendering the mid-TMS regions of homologous TMSs 2 and 7 relatively immobile. While the TMS that is involved in substrate binding in MalT is part of the homologous bundle that holds the two separate halves of the transport assembly (two proteins) together, an unequal effect of the two knockouts was observed for UlaA where both V-motifs are free from such dimer interface interactions. PMID- 27720946 TI - 6-(3,4-Dihydro-1H-isoquinoline-2-yl)-N-(6-methoxypyridine-2-yl) nicotinamide-26 (DIMN-26) decreases cell proliferation by induction of apoptosis and downregulation of androgen receptor signaling in human prostate cancer cells. AB - Previously, we reported that 6-(3,4-dihydro-1H-isoquinolin-2-yl)-N-(6 methylpyridin-2-yl) nicotinamide (DIMN) analogues inhibited the growth of prostate cancer cells as an anti-androgenic compound. In the present study, we evaluated cytotoxic effects of these DIMN derivatives and found that DIMN-26 most potently inhibited the proliferation of the LNCap-LN3 androgen-dependent and DU145 androgen-independent prostate cancer cells through induction of G2/M phase cell cycle arrest and subsequent apoptosis. The G2/M phase arrest was found due to increases in the activation of cdc2 (also known as cyclin-dependent kinase 1, CDK1)/cyclin B1 complex. DIMN-26 also induced apoptosis in LNCap-LN3 and DU145 prostate cancer cells through activation of caspase-3, -8, and -9, and cleavage of poly(ADP-ribose) polymerase-1 (PARP-1). In addition, DIMN-26 caused the dephosphorylation and mitochondrial accumulation of Bad protein and induced the loss of mitochondria membrane potential, consequently releasing cytochrome c into the cytosol of the cell. Furthermore, overexpression of AKT protein significantly reduced DIMN-26-induced PARP-1 cleavage and p-Bad decrease and cdc2 activation. In addition, DIMN-26 inhibited the 5alpha-dihydrotestosterone (DHT)-induced cell growth and proliferation and nuclear translocation and transcriptional activities of androgen receptor (AR) in LNCap-LN3 prostate cancer cells. Consistent with these findings, DIMN-26 significantly inhibited the DHT-induced expression of AR response genes (ARGs), such as prostate-specific antigen (PSA), AR, beta2 microglobulin (B2M), selenoprotein P (SEPP1), and ste20-related proline-alanine rich kinase (SPAK) in LNCap-LN3 prostate cancer cells. Taken together, these results suggest that DIMN-26 plays a therapeutic role not only in induction of G2/M arrest and apoptosis but also in suppression of androgen receptor signaling in androgen-dependent and androgen-independent prostate cancer cells. PMID- 27720947 TI - The plant-derived triterpenoid tingenin B is a potent anticancer agent due to its cytotoxic activity on cancer stem cells of breast cancer in vitro. AB - Despite the rapid advances in chemotherapy regimens, the outcome of patients with breast cancer is not satisfactory. One of the reasons of this dissatisfaction is that subsets of cells in tumors which referred as cancer stem cells (CSCs) show and/or gain resistance to therapies. Thus, compounds that target CSCs are urgently needed. Since some are already used in the clinic, natural products have great potential for further development as anti cancer drugs. The aim of this study is to investigate the cytotoxic activity of tingenin b (or 22beta hydroxytingenone) which is a quinone-methide triterpenoid structurally related to tingenone, against breast CSCs (stem-cell enriched population from MCF-7 cell line, MCF-7s). It has been found that tingenin b was cytotoxic against MCF-7s (IC50 value for 48 h was found to be 2.38 MUM) by inducing apoptosis. It was evident by Annexin V staining positivity, decreased mitochondrial membrane potential and Bcl-2 dephosphorylation with a concomitant increase in Bax protein expression. In addition, endoplasmic reticulum stress was also found to be involved in tingenin b-induced cell death. In conclusion, the results warrant further studies aimed at elucidating and corroborating its possible use in the treatment of breast cancer. PMID- 27720948 TI - Functional changes in brain activity after hypnosis in patients with dental phobia. AB - Visiting the dentist is often accompanied by apprehension or anxiety. People, who suffer from specific dental phobia (a disproportional fear of dental) procedures show psychological and physiological symptoms which make dental treatments difficult or impossible. For such purposes, hypnosis is often used in dental practice as an alternative for a number of treatments adjuvant or instead of sedation or general anaesthetics, as medication is often associated with risks and side effects. This is the first study to address the effects of a brief dental hypnosis on the fear processing structures of the brain in dental phobics using functional magnetic resonance imaging (fMRI). 12 dental phobics (DP; mean 34.9years) and 12 healthy controls (CO; mean 33.2years) were scanned with a 3T MRI whole body-scanner observing brain activity changes after a brief hypnotic invervention. An fMRI event-related design symptom provocation task applying animated audio-visual pseudorandomized strong phobic stimuli was presented in order to maximize the fearful reactions during scanning. Control videos showed the use of familiar electronic household equipment. In DP group, main effects of fear condition were found in the left amygdala and bilaterally in the anterior cingulate cortex (ACC), insula and hippocampu (R
